        "evidence": "The encoder-decoder based framework BIBREF0, BIBREF1, BIBREF2 is the dominant approach for neural machine translation (NMT) BIBREF3, BIBREF4. Although the encoder and decoder usually adopt the same model structure (RNN BIBREF5, CNN BIBREF6 or self-attention BIBREF3, BIBREF7) and the same number of layers, they perform different functionalities: the encoder extracts the hidden representations of the source sentence, and the decoder generates target tokens conditioned on the source hidden representations as well as the previous generated tokens.\nWhile most existing works focus on the design and improvement of encoder-decoder framework for NMT BIBREF8, BIBREF6, BIBREF3, BIBREF9 as well as its detailed analyses BIBREF10, BIBREF11, BIBREF12, BIBREF13, few works concentrate on the characteristics and functionalities of the encoder and the decoder, which are valuable to understand this popular framework and improve its performance in NMT. Therefore, in this paper, we conduct a study and aim to understand the characteristics of the encoder and the decoder in NMT. We observe some interesting phenomena:\nThe decoder handles an easier task than the encoder. 1) We find that adding more layers to the encoder achieves larger improvements than adding more layers to the decoder. 2) We also compare the training time of the encoder and decoder by fixing the parameters of a well-trained decoder (encoder), and just update the parameters of the encoder (decoder). We found that the decoder converges faster than the encoder. These two results suggest that the decoder handles an easier task than the encoder in NMT.\nThe decoder is more sensitive to the input noise than the encoder. We randomly add different level of noise to the input of the encoder and decoder respectively during inference, and find that adding noise to the input of the decoder leads to better accuracy drop than that of the encoder.\nWe further analyze why the decoder is more sensitive by masking the previous tokens, and comparing autoregressive NMT with the non-autoregressive counterpart. We find that the preceding tokens in the decoder provide strong conditional information, which partially explain the previous two observations on the decoder.\nWe believe our studies on the different characteristics of the encoder and decoder will inspire the following research on the encoder-decoder framework as well as improve the performance on NMT and other encoder-decoder based tasks.\nWe find that the preceding tokens in the decoder provide strong conditional information, which partially explain the previous two observations on the decoder.

        "question": "What do they want to predict in their paper?",
        "answer": "To predict the political role of Internet trolls (left, right, and news feed) in a realistic, unsupervised scenario.",
        "evidence": "Internet “trolls” are users of an online community who quarrel and upset people, seeking to sow discord by posting inflammatory content. More recently, organized “troll farms” of political opinion manipulation trolls have also emerged.\nSuch farms usually consist of state-sponsored agents who control a set of pseudonymous user accounts and personas, the so-called “sockpuppets”, which disseminate misinformation and propaganda in order to sway opinions, destabilize the society, and even influence elections BIBREF0.\nThe behavior of political trolls has been analyzed in different recent circumstances, such as the 2016 US Presidential Elections and the Brexit referendum in UK BIBREF0, BIBREF1. However, this kind of analysis requires painstaking and time-consuming manual labor to sift through the data and to categorize the trolls according to their actions. Our goal in the current paper is to automate this process with the help of machine learning (ML). In particular, we focus on the case of the 2016 US Presidential Elections, for which a public dataset from Twitter is available. For this case, we consider only accounts that post content in English, and we wish to divide the trolls into some of the functional categories identified by BIBREF0: left troll, right troll, and news feed.\nWe consider two possible scenarios. The first, prototypical ML scenario is supervised learning, where we want to learn a function from users to categories {left, right, news feed}, and the ground truth labels for the troll users are available. This scenario has been considered previously in the literature by BIBREF2. Unfortunately, a solution for such a scenario is not directly applicable to a real-world use case. Suppose a new troll farm trying to sway the upcoming European or US elections has just been discovered. While the identities of the accounts might be available, the labels to learn from would not be present. Thus, any supervised machine learning approach would fall short of being a fully automated solution to our initial problem.\nA more realistic scenario assumes that labels for troll accounts are not available. In this case, we need to use some external information in order to learn a labeling function. Indeed, we leverage more persistent entities and their labels: news media. We assume a learning scenario with distant supervision where labels for news media are available. By combining these labels with a citation graph from the troll accounts to news media, we can infer the final labeling on the accounts themselves without any need for manual labeling.\nOne advantage of using distant supervision is that we can get insights about the behavior of a newly-discovered troll farm quickly and effortlessly. Differently from troll accounts in social media, which usually have a high churn rate, news media accounts in social media are quite stable. Therefore, the latter can be used as an anchor point to understand the behavior of trolls, for which data may not be available.\nWe rely on embeddings extracted from social media. In particular, we use a combination of embeddings built on the user-to-user mention graph, the user-to-hashtag mention graph, and the text of the tweets of the troll accounts. We further explore several possible approaches using label propagation for the distant supervision scenario.\nAs a result of our approach, we improve the classification accuracy by more than 5 percentage points for the supervised learning scenario. The distant supervision scenario has not previously been considered in the literature, and is one of the main contributions of the paper. We show that even by hiding the labels from the ML algorithm, we can recover 78.5% of the correct labels.\nThe contributions of this paper can be summarized as follows:\nWe predict the political role of Internet trolls (left, news feed, right) in a realistic, unsupervised scenario, where labels for the trolls are not available, and which has not been explored in the literature before.\nWe propose a novel distant supervision approach for this scenario, based on graph embeddings, BERT, and label propagation, which projects the more-commonly-available labels for news media onto the trolls who cited these media.\nWe improve over the state of the art in the traditional, fully supervised setting, where training labels are available.\nWe predict the political role of Internet trolls (left, news feed, right) in a realistic, unsupervised scenario, where labels for the trolls are not available, and which has not been explored in the literature before.",

        "evidence": "We evaluate our model through two types of metrics. The BLEU score BIBREF34 aims at measuring to what extent the generated descriptions are literally closed to the ground truth. The second category designed by BIBREF10 is more qualitative.\nThe BLEU score BIBREF34 is commonly used as an evaluation metric in text generation tasks. It estimates the correspondence between a machine output and that of a human by computing the number of co-occurrences for ngrams ($n \\in {1, 2, 3, 4}$) between the generated candidate and the ground truth. We use the implementation code released by BIBREF35.\nThese metrics estimate the ability of our model to integrate elements from the table in its descriptions. Particularly, they compare the gold and generated descriptions and measure to what extent the extracted relations are aligned or differ. To do so, we follow the protocol presented in BIBREF10. First, we apply an information extraction (IE) system trained on labeled relations from the gold descriptions of the RotoWire train dataset. Entity-value pairs are extracted from the descriptions. For example, in the sentence Isaiah Thomas led the team in scoring, totaling 23 points [...]., an IE tool will extract the pair (Isaiah Thomas, 23, PTS). Second, we compute three metrics on the extracted information:\n$\\bullet $ Relation Generation (RG) estimates how well the system is able to generate text containing factual (i.e., correct) records. We measure the precision and absolute number (denoted respectively RG-P% and RG-#) of unique relations $r$ extracted from $\\hat{y}_{1:T}$ that also appear in $s$.\n$\\bullet $ Content Selection (CS) measures how well the generated document matches the gold document in terms of mentioned records. We measure the precision and recall (denoted respectively CS-P% and CS-R%) of unique relations $r$ extracted from $\\hat{y}_{1:T}$ that are also extracted from $y_{1:T}$.\n$\\bullet $ Content Ordering (CO) analyzes how well the system orders the records discussed in the description. We measure the normalized Damerau-Levenshtein distance BIBREF36 between the sequences of records extracted from $\\hat{y}_{1:T}$ that are also extracted from $y_{1:T}$.\nCS primarily targets the “what to say\" aspect of evaluation, CO targets the “how to say it\" aspect, and RG targets both. Note that for CS, CO, RG-% and BLEU metrics, higher is better; which is not true for RG-#. The IE system used in the experiments is able to extract an average of 17 factual records from gold descriptions. In order to mimic a human expert, a generative system should approach this number and not overload generation with brute facts.\nThe IE system used in the experiments is able to extract an average of 17 factual records from gold descriptions.",

User comments, however, can also be abusive (e.g., bullying, profanity, hate speech), damaging the reputation of news portals, making them liable to fines (e.g., when hosting comments encouraging illegal actions), and putting off readers. Large news portals often employ moderators, who are frequently overwhelmed by the volume and abusiveness of comments. Readers are disappointed when non-abusive comments do not appear quickly online because of moderation delays. Smaller news portals may be unable to employ moderators, and some are forced to shut down their comments.\nIn previous work BIBREF0 , we introduced a new dataset of approx. 1.6M manually moderated user comments from a Greek sports news portal, called Gazzetta, which we made publicly available.

        "question": "When were the concept of maps introduced as a teaching tool?",
        "answer": "In 1972.",
        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ). We make these resources publicly available under a permissive license.\nIntroduced in 1972 as a teaching tool (Novak and Canas ˜ , 2007), concept maps have found many applications in education (Edwards and Fraser, 1983; Roy, 2008), for writing assistance (Villalon, 2012) or to structure information repositories (Briggs et al., 2004; Richardson and Fox, 2005).",

        "answer": "RNNs require only a small fraction of memory used, about 5% of traditional shallow SMT models，and they are optimized such that every module is trained to jointly improve translation quality.",
        "evidence": "The use of RNNs in the field of Statistical Machine Translation (SMT) has revolutionised the approaches to automated translation. As opposed to traditional shallow SMT models, which require a lot of memory to run, these neural translation models require only a small fraction of memory used, about 5% BIBREF0 . Also, neural translation models are optimized such that every module is trained to jointly improve translation quality. With that being said, one of the main downsides of neural translation models is the heavy corpus requirement in order to ensure learning of deeper contexts. This is where the application of these encoder decoder architectures in translation to and/or from morphologically rich languages takes a severe hit.\nFor any language pair, the efficiency of an MT system depends on two major factors: the availability and size of parallel corpus used for training and the syntactic divergence between the two languages i.e morphological richness, word order differences, grammatical structure etc. BIBREF0 . The main differences between the languages stem from the fact that languages similar to English are predominantly fusional languages whereas many of the morphologically rich languages are agglutinative in nature. The nature of morphologically rich languages being structurally and semantically discordant from languages like English adds to the difficulty of SMT involving such languages.\nIn morphologically rich languages, any suffix can be added to any verb or noun to simply mean one specific thing about that particular word that the suffix commonly represents (agglutination). This means that there exists a lot of inflectional forms of the same noun and verb base words, conveying similar notions. For example, in Tamil, there are at least 30,000 inflectional forms of any given verb and about 5,000 forms of inflectional forms for any noun. The merged words carry information about part of speech (POS) tags, tense, plurality and so forth that are important for analyzing text for Machine Translation (MT). Not only are these hidden meanings not captured, the corresponding root words are trained as different units, thereby increasing the complexity of developing such MT systems BIBREF1 .\nTo add to the complexities of being a morphologically rich language, there are several factors unique to Tamil that make translation very difficult. The availability of parallel corpus for Tamil is very scarce. Most of the other models in the field of English–Tamil MT have made use of their own translation corpora that were manually created for the purposes of research. Most of these corpora are not available online for use.\nAnother issue specific to Tamil is the addition of suffix characters included to the words in the language for smoothness in pronunciation. These characters are of so many different types; there is a unique suffix for each and every consonant in the language. These suffixes degrade performance of MT because the same words with different such pronounciation-based suffixes will be taken as different words in training.\nAlso to take into consideration is the existence of two different forms of the language being used. Traditionally defined Tamil and its pronunciations aren't acoustically pleasing to use. There's no linguistic flow between syllables and its usage in verbal communication is time consuming. Therefore, there exists two forms of the language, the written form, rigid in structure and syntax, and the spoken form, in which the flow and pace of the language is given priority over syntax and correctness of spelling. This divide leads to the corpus having 2 different versions of the language that increase the vocabulary even with the same words. This can be evidently seen in the corpus between the sentences used in the Bible, which is in traditional Tamil and sentences from movie subtitles, being in spoken Tamil format.\nTo account for such difficulties, a trade-off between domain specificity and size of the corpus is integral in building an English–Tamil neural MT system.\nThe use of RNNs in the field of Statistical Machine Translation (SMT) has revolutionised the approaches to automated translation. As opposed to traditional shallow SMT models, which require a lot of memory to run, these neural translation models require only a small fraction of memory used, about 5% (Cho et al. 2014a).

        "evidence": "Low dimensional word representations (embeddings) have become a key component in modern NLP systems for language modeling, parsing, sentiment classification, and many others. These embeddings are usually derived by employing the distributional hypothesis: that similar words appear in similar contexts BIBREF0 .\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix BIBREF1 . The most well-known predictive model, which has become eponymous with word embedding, is word2vec BIBREF2 . Popular counting models include PPMI-SVD BIBREF3 , GloVe BIBREF4 , and LexVec BIBREF5 .\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.\nfastText BIBREF6 addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors. This addresses both issues above as learned information is shared through the n-gram vectors and from these OOV word representations can be constructed.\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , but the method proposed here should transfer to GloVe unchanged.\nThe LexVec objective is modified such that a word's vector is the sum of all its subword vectors.\nWe compare 1) the use of n-gram subwords, like fastText, and 2) unsupervised morphemes identified using Morfessor BIBREF11 to learn whether more linguistically motivated subwords offer any advantage over simple n-grams.\nTo evaluate the impact subword information has on in-vocabulary (IV) word representations, we run intrinsic evaluations consisting of word similarity and word analogy tasks. The incorporation of subword information results in similar gains (and losses) to that of fastText over Skip-gram. Whereas incorporating n-gram subwords tends to capture more syntactic information, unsupervised morphemes better preserve semantics while also improving syntactic results. Given that intrinsic performance can correlate poorly with performance on downstream tasks BIBREF12 , we also conduct evaluation using the VecEval suite of tasks BIBREF13 , in which\nall subword models, including fastText, show no significant improvement over word-level models.\nWe verify the model's ability to represent OOV words by quantitatively evaluating nearest-neighbors. Results show that, like fastText, both LexVec n-gram and (to a lesser degree) unsupervised morpheme models give coherent answers.\nThis paper discusses related word ( $§$ \"Related Work\" ), introduces the subword LexVec model ( $§$ \"Subword LexVec\" ), describes experiments ( $§$ \"Materials\" ), analyzes results ( $§$ \"Results\" ), and concludes with ideas for future works ( $§$ \"Conclusion and Future Work\" ).\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.",

Therefore, we compare our approach with the following baselines:\n• DNN: Standard deterministic neural network trained using cross-entropy loss.\n• DNN-SN:DNN with SN.\n• DNN-SRN: DNN with SRN.\n• SNGP: Spectrally Normalized Gaussian Process.\n• DUQ: Deterministic Uncertainty Quantification.\n• Mixup: Standard Mixup training.\n• KFAC-LLLA: KFAC-Laplace Last Layer Approximation. A method that makes a model Bayesian at test time by taking Laplace approximation of the last layer using a Kronecker-Factored approximation. For the sake of completeness, we provide a simple outline of this approach in Appendix B. Code base For fair comparisons, we developed our own code base for all the approaches mentioned above (except SNGP and DUQ) and performed an extensive hyperparameter search to obtain the strongest possible baselines. For SNGP, we used the available code and made sure that we follow exactly the same procedure as mentioned in their original paper. For DUQ, the original paper did not perform large scale experiments similar to ours. Unfortunately, we could not manage to make their code work on C100 as it exhibited unstable behaviour. For this reason, we borrowed numbers for DUQ from the SNGP paper. Please note that the authors of SNGP performed non-trivial modifications to the original DUQ methodology to make it work on C100. Further details provided in Appendix C.\nWe use SGD with Nesterov momentum 0.9 and a weight decay of 5 × 10 −4 . For WRN, we apply a dropout p = 0.1 at train time. We perform extensive cross-validation of all the hyperparameters for all the baselines. Details provided in Appendix C.\nEvaluation Metrics For calibration, we employ: (1) the widely used Expected Calibration Error (ECE), and (2) the recently proposed Adaptive ECE (AdaECE). For all the methods, the ECE and AdaECE are computed after performing temperature scaling with a cross-validated temperature parameter. Metrics and uncertainty measures used for out-of-distribution detection are discussed in detail in Section 5.1.3.\nA particularly thriving sub-field of research in Deep Neural Networks (DNNs) concerns devising efficient approaches towards obtaining reliable predictive uncertainty. NNs are known to be overconfident for both, in-and out-distribution samples (i.e. for samples coming from the same distribution from which the training distribution has been sampled (IND samples) and for samples not coming from such distribution), leading to highly unreliable uncertainty estimates. They can be wrong with very high confidence not only on the test data similar to the one they have been trained on, but also when facing previously-unseen conditions. The overconfidence problem becomes even more concerning when just slight changes in illumination, atmospheric conditions or in the image capturing process (domain-shift) can severely damage the actual accuracy of the model. A desirable property of any model is to be robust to such superficial changes that do not affect the label of the classified image, and to become uncertain (or indecisive) when exposed to samples from a distribution different from the training distribution.\nWhile the literature suggests that classifiers whose predictive distributions increase their entropy the further away the test input gets from the training data are desirable, the implementation of models satisfying such a property is not scalable, and can only occur at the cost of performing crude approximations and by non-trivial modifications to the architecture of the neural network. Such modifications sometimes lead to degraded accuracy.\nOur motivation behind this work is based on the following observations. (1) We find that a trained network (DNN) do not project out-of-distribution (OOD) and domain-shifted (DS) samples arbitrarily away from the training data. In fact, all the OOD and domain-shifted inputs that we considered (detailed discussion in Section 3) are projected within the smallest hypersphere that contains all of the IND test data. Therefore, it might not be necessary to enforce the network to be uncertain everywhere away from the data, and perhaps, in-distribution data can be used to mimic the regions where OOD and DS samples are being projected. (2) DNNs tend to embed OOD and DS samples in high confidence (low-entropy) regions (see Figure). This contradicts the desired ideal behaviour, that would require a model to map such samples in high-entropy regions.\nFigure: DNN (Left), Ours (Right). Interpolation experiment on CIFAR10 to show embeddings of the linear interpolation of two randomly picked input samples from class 1 (purple) and class 2 (yellow). Red and green samples are classified as class 1, and orange and blue samples as class 2. As the color changes from red to green, the predictive entropy increases. Same for the color change from blue to orange. Note, DNN classifies interpolated points with very high confidence (low entropy) even if the samples shift drastically from the data. However, Mix-MaxEnt maps these samples into a wide high-entropy region. Details of this visualization are provided in Appendix F. More exhaustive visualizations of this phenomenon are provided in Section 5.2.2. Given the observations above, we propose a simple entropy maximization regularizer (called Mix-MaxEnt), that induces a high entropy barrier between class clusters, while the cross-entropy optimization objective keeps the entropy low close to the class clusters. The entropy regularizer is enforced for samples synthesized using the convex combination of a pair of samples from two different classes of the in-distribution training data. When combined with the crossentropy loss, this regularizer prefers a maximum likelihood solution such that the uncertainty of the network increases while moving away from the embeddings of one class in the direction of another, and learns features that are robust to local input perturbations.\nThrough extensive experiments using WideResNet28-10 and ResNet50 architerctures on CIFAR10 and CIFAR100 datasets, we demonstrate that our method outperforms all existing single model baselines in providing clean data accuracy. On Domain-Shift experiments, it provides remarkably improved accuracy compared to all the baselines including Deep Ensembles (DE). For instance, it provides 4.8% and 4.7% improvements over the highly competitive DE and SNGP, respectively, on CIFAR-10 using WideResNet. In terms of reliable uncertainty estimates, it is either the best or, in a few cases, extremely competitive with respect to the best performing one, with only slightly inferior performance. Overall, our experiments show that Mix-MaxEnt is by far the best performing one compared to the existing single model approaches.\nWe would like to highlight that, along with its effectiveness, one of the core strengths of our approach is its simplicity. As opposed to the recently proposed, it does not require any modifications to the architectures and does not trade accuracy in order to improve uncertainty estimates. And, as opposed to the extremely competitive DE, it is a single deterministic model, hence, extremely efficient.\nWe consider both deterministic and Bayesian approaches for comparison. Following (Liu et al., 2020a), we also create two additional strong and simple baselines where a ResNet is enforced to be bi-Lipschitz using Spectral Normalization (SN) (Miyato et al., 2018a) and Stable Rank Normalization (SRN) (Sanyal et al., 2020). Note, we are the first to consider SRN for these experiments as it induces more compact clusters in the feature space than SN (we provide a simple mathematical proof of this in the Appendix A). Therefore, we compare our approach with the following baselines: • DNN: Standard deterministic neural network trained using cross-entropy loss. • DNN-SN:DNN with SN (Miyato et al., 2018a). • DNN-SRN: DNN with SRN (Sanyal et al., 2020). • SNGP: Spectrally Normalized Gaussian Process (Liu et al., 2020a). • DUQ: Deterministic Uncertainty Quantification (van Amersfoort et al., 2020). • Mixup: Standard Mixup training (Zhang et al., 2018). • KFAC-LLLA: KFAC-Laplace Last Layer Approximation (Kristiadi et al., 2020). A method that makes a model Bayesian at test time by taking Laplace approximation of the last layer using a Kronecker-Factored approximation (Ritter et al., 2018). For the sake of completeness, we provide a simple outline of this approach in Appendix B. • DE: Deep Ensembles (Lakshminarayanan et al., 2017) with 5 members. Note, it is almost 5x slower than all other approaches mentioned above.****Through extensive experiments using WideResNet28-10 and ResNet50 architerctures on CIFAR10 and CIFAR100 datasets, we demonstrate that our method outperforms all existing single model baselines in providing clean data accuracy.",

        "question": "Do the language varieties differ mainly in lexicographic clues?",
        "answer": "Yes, they do.",
        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nOur hypothesis is that language varieties differ mainly in lexicographic clues.",

Therefore, we think that there is a room for improvements which can be achieved by interactively asking for additional information in conversational dialogs with users. This extra information can be used for improving policies of dialog systems. We call this approach the interactive learning from dialogs.\nWe can improve dialog systems in several aspects through interactive learning in a direct interaction with users. First, the most straightforward way obviously is getting the correct answer for questions that the system does not know. We can try to ask users for answers on questions that the system encountered in a conversation with a different user and did not understand it. Second, the system can ask the user for a broader explanation of a question. This explanation could help the system to understand the question and provide the correct answer. In addition, the system can learn correct policy for the question which allows providing answers without asking any extra information for similar questions next time. We hypothesize that users are willing to give such explanations because it could help them to find answers for their own questions. The last source of information that we consider for interactive learning is rephrasing, which could help when the system does know the concept but does not know the correct wording. This area is extensively studied for the purposes of information retrieval BIBREF5 , BIBREF6 .\nThe main purpose of the collected dataset is to enable interactive learning using the steps proposed above and potentially to evaluate how different systems perform on this task.\nWe can try to ask users for answers on questions that the system encountered in a conversation with a different user and did not understand it.",

        "evidence": "Recently, the number of public datasets in the Linked Data cloud has significantly grown to almost 10 thousands. At the time of writing, at least four of these datasets contain more than one billion triples each. This huge amount of available data has become a fertile ground for Machine Learning and Data Mining algorithms. Today, applications of machine-learning techniques comprise a broad variety of research areas related to Linked Data, such as Link Discovery, Named Entity Recognition, and Structured Question Answering. The field of Knowledge Graph Embedding (KGE) has emerged in the Machine Learning community during the last five years. The underlying concept of KGE is that in a knowledge base, each entity and relation can be regarded as a vector in a continuous space. The generated vector representations can be used by algorithms employing machine learning, deep learning, or statistical relational learning to accomplish a given task. Several KGE approaches have already shown promising results on tasks such as link prediction, entity recommendation, question answering, and triplet classification BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Moreover, Distributional Semantics techniques (e.g., Word2Vec or Doc2Vec) are relatively new in the Semantic Web community. The RDF2Vec approaches BIBREF4 , BIBREF5 are examples of pioneering research and to date, they represent the only option for learning embeddings on a large knowledge graph without the need for state-of-the-art hardware.

Her genre-spanning discography, songwriting abilities and artistic reinventions have received critical praise and wide media coverage. Born in West Reading, Pennsylvania, Swift moved to Nashville at age 14 to become a country artist. She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country artist to write a U.S. platinum-certified album.\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history. She is the most streamed woman on Spotify and the only act to have five albums open with over one million copies sold in the US. Among her accolades are 12 Grammy Awards, including three Album of the Year wins; an Emmy Award; 40 American Music Awards; 29 Billboard Music Awards; three IFPI Global Recording Artist of the Year awards; and 92 Guinness World Records.

We use the 1,755 \"observational\" samples, where the experimental conditions involve only perturbing receptor enzymes, and not any signaling molecules, as described in. To make the ground truth network more similar to a latent factor causal model, we perform three data-processing steps: (1) we \"condition\" on PKA, by regressing it out of the dataset, (2) we \"remove\" the direct effect of Raf on Mek, and (3) we \"marginalize\" out PIP3 and PKC by removing the corresponding columns from the dataset. We \"remove\" the direct effect of Raf on Mek as follows. First, we regress Mek on its two remaining parents, Raf and PKC. Call the resulting regression coefficient for Raf β Raf . For each sample, we subtract the value of Raf times the β Raf from the value of Mek. Note that we do not remove the direct effect of PLCγ on PIP2, since then our algorithm collapses all nodes into a single cluster. The processed graph is show in Fig..

During the training process, we freeze several layers of the pre-trained universal encoder to avoid the degeneracy issue BIBREF27.\nDirectly translate source sentences into target sentences with the parent model, which benefits from the availability of the universal encoder.\nThe key difficulty of this method is to ensure the intermediate representations of the universal encoder are language invariant.

        "evidence": "Arsenal Football Club is an English professional football club based in Islington, London. Arsenal plays in the Premier League, the top flight of English football. The club has won 13 league titles (including one unbeaten title), a record 14 FA Cups, two League Cups, 16 FA Community Shields, one European Cup Winners' Cup, and one Inter-Cities Fairs Cup. In terms of trophies won, it is the third-most successful club in English football.\n\nArsenal was the first club from the South of England to join the Football League in 1893, and they reached the First Division in 1904. Relegated only once, in 1913, they continue the longest streak in the top division, and have won the second-most top-flight matches in English football history. In the 1930s, Arsenal won five League Championships and two FA Cups, and another FA Cup and two Championships after the war. In 1970–71, they won their first League and FA Cup Double. Between 1989 and 2005, they won five League titles and five FA Cups, including two more Doubles. They completed the 20th century with the highest average league position. Between 1998 and 2017, Arsenal qualified for the UEFA Champions League for nineteen consecutive seasons.\n\nHerbert Chapman, who changed the fortunes of Arsenal forever, won the club its first silverware, and his legacy led the club to dominate the 1930s decade; Chapman, however, died of pneumonia in 1934, aged 55. He helped introduce the WM formation, floodlights, and shirt numbers; he also added the white sleeves and brighter red to the club's jersey. Arsène Wenger is the longest-serving manager and won the most trophies. He won a record seven FA Cups, and his title-winning team set an English record for the longest top-flight unbeaten league run at 49 games between 2003 and 2004, receiving the nickname The Invincibles.\n\nIn 1886, munitions workers at the Royal Arsenal in Woolwich founded the club as Dial Square. In 1913 the club crossed the city to Arsenal Stadium in Highbury, becoming close neighbours of Tottenham Hotspur, and creating the North London derby. In 2006, they moved to the nearby Emirates Stadium. With an annual revenue of £340.3m in the 2019–20 season, Arsenal was estimated to be worth US$2.68 billion by Forbes, making it the world's eighth most valuable club, while it is one of the most followed on social media.

The manner he dealt with the top fast bowlers of the day, like as Allan Donald.

Seasonal change in the angle of sunlight, caused by the tilt of Earth's axis, is the basic mechanism that results in warmer weather in summer than in winter.Change in day length is another factor.\n\nPresents a case when sunlight shines on Earth at a lower angle (Sun closer to the horizon), the energy of the sunlight is spread over a larger area, and is therefore weaker than if the Sun is higher overhead and the energy is concentrated on a smaller area.",
        "answer": "It's commonly known that the sun is more intense at higher altitudes. However, contrary to popular belief, the sun is not more intense due to being closer to the sun, but the angle of incidence of the sun. The angle of incidence is steeper, and therefore the density of the sun's  radiant energy is concentrated to a high density in a smaller area. This makes the sun's energy more intense",

Her genre-spanning discography, songwriting abilities and artistic reinventions have received critical praise and wide media coverage. Born in West Reading, Pennsylvania, Swift moved to Nashville at age 14 to become a country artist. She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country artist to write a U.S. platinum-certified album.\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history. She is the most streamed woman on Spotify and the only act to have five albums open with over one million copies sold in the US. Among her accolades are 12 Grammy Awards, including three Album of the Year wins; an Emmy Award; 40 American Music Awards; 29 Billboard Music Awards; three IFPI Global Recording Artist of the Year awards; and 92 Guinness World Records. Swift has been featured in rankings such as Rolling Stone's 100 Greatest Songwriters of All Time, Billboard's Greatest of All Time Artists, the Time 100 and Forbes Celebrity 100. Honored with titles such as Artist of the Decade and Woman of the Decade, Swift is an advocate for artists' rights and women's empowerment.

BIBREF14 extended the tree kernels described in the previous section to operate on text pairs. The underlying idea is that this task is characterized by several syntactic/semantic patterns that a kernel machine can automatically capture from the training material. We can assess a text pair as a paraphrase if it shows a valid transformation rule that we observed in the training data. The following example can clarify this concept. A simple paraphrase rewriting rule is the active-passive transformation, such as in “Federer beat Nadal” and “Nadal was defeated by Federer”. The same transformation can be observed in other paraphrases, such as in “Mark studied biology” and “Biology was learned by Mark”. Although these two pairs of paraphrases have completely different topics, they have a very similar syntactic structure.\nIn this section, the experimental analysis of the proposed models is presented.

        "answer": "`project' word and document representations from semantic space of language A to semantic space of language B.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nThen, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B.",

        "evidence": "From the point of view of dialog systems providing general information from a knowledge base, the most limiting factor is that a large portion of the questions is understood poorly.\nCurrent approaches BIBREF3 , BIBREF4 can only achieve around 50% accuracy on some question answering datasets. Therefore, we think that there is a room for improvements which can be achieved by interactively asking for additional information in conversational dialogs with users. This extra information can be used for improving policies of dialog systems. We call this approach the interactive learning from dialogs.\nWe can improve dialog systems in several aspects through interactive learning in a direct interaction with users. First, the most straightforward way obviously is getting the correct answer for questions that the system does not know. We can try to ask users for answers on questions that the system encountered in a conversation with a different user and did not understand it. Second, the system can ask the user for a broader explanation of a question. This explanation could help the system to understand the question and provide the correct answer. In addition, the system can learn correct policy for the question which allows providing answers without asking any extra information for similar questions next time.

After the outbreak of World War II, Rozenfeld was sent to the Warsaw Ghetto, where he worked as a teacher. He belonged to the Polish Workers' Party and was a member of the Main Command of the Jewish Combat Organization. He stayed in a bunker with Mordechai Anielewicz at 18 Miła Street. On May 18, 1943, together with a group of Jewish fighters, he got through the sewers to Prosta Street.\n\nAfter the fall of the uprising, Rozenfeld took refuge in forests near Wyszków, where he fought in a unit of the People's Guard. Together with his companions he was handed over to the Germans by a forest ranger from Krawcowizna. Twelve partisans, including Michał Rozenfeld, were killed at that time.\n\nIn 1945 he was posthumously awarded the Silver Cross of the Order of Virtuti Militari.\n\nRozenfeld is buried in a mass grave of the People's Guard partisans in the Jewish cemetery on Okopowa Street in Warsaw (quarter 31, row 3).",

To extract event pairs tagged with discourse relations, we used the Japanese dependency parser KNP and in-house postprocessing scripts BIBREF14. KNP used hand-written rules to segment each sentence into what we conventionally called clauses (mostly consecutive text chunks), each of which contained one main predicate. KNP also identified the discourse relations of event pairs if explicit discourse connectives BIBREF4 such as “ので” (because) and “のに” (in spite of) were present. We treated Cause/Reason (原因・理由) and Condition (条件) in the original tagset BIBREF15 as Cause and Concession (逆接) as Concession, respectively. Here is an example of event pair extraction.\nWe constructed our seed lexicon consisting of 15 positive words and 15 negative words, as shown in Section SECREF27.

        "evidence": "",
        "answer": "Compared with active income which you earn in exchange of your time and efforts, passive income comes passively as you can sit aside after proper initial setups. Some argue that time-average investing in index funds is considered passive investing. Time-average-investing or dollar cost averaging investing means you invest a fixed amount in the index fund recurringly with a given frequency, usually monthly or biweekly, regardless of the fund price. You can set it up with auto-payment or auto-investment through your brokerage and let it build your wealth over time. Index funds mirror the performance of a collection of selected stocks, thus providing a diversified strategy by its nature. SP500 index has a proven performance record that beats most active fund managers. In addition, real estate investment is somehow passive if you leave all the property management to professionals. However, the fact that it requires a certain amount of equity to get started makes younger investors shy away from it. For the younger generation, generating passive income from content they publish on social media has become a popular choice. For example, publishing videos to your YouTube channel requires time and effort to create the content. But once the video is live, it starts to generate income streams with more and more people watching your videos for years to come.",

        "question": "Why is global attention mechanism preferred?",
        "answer": "Because the differences in the structures of the languages cannot be mapped efficiently to enable lookup into the right parts of the source sentence.",
        "evidence": "The model used for translation is the one implemented by Bahdanau et al. Bahdanau2014. A bidirectional LSTM encoder first takes the source sentence and encodes it into a context vector which acts as input for the decoder. The decoder is attention-based where the hidden states of the decoder get as input the weighted sum of all the hidden layer outputs of the encoder alongwith the output of the previous hidden layer and the previously decoded word. This provides a contextual reference into the source language sentence BIBREF4 .\nNeural Machine Translation models directly compute the probability of the target language sentence given the source language sentence, word by word for every time step. The model with a basic decoder without the attention module computes the log probability of target sentence given source sentence as the sum of log probabilities of every word given every word before that. The attention-based model, on the other hand, calculates: DISPLAYFORM0 \nwhere INLINEFORM0 is the number of words in the target sentence, INLINEFORM1 is the target sentence, INLINEFORM2 is the source sentence, INLINEFORM3 is the fixed length output vector of the encoder and INLINEFORM4 is the weighted sum of all the hidden layer outputs of the encoder at every time step. Both the encoder's output context vector and the weighted sum (known as attention vector) help to improve the quality of translation by enabling selective source sentence lookup.\nThe decoder LSTM computes: DISPLAYFORM0 \nwhere the probability is computed as a function of the decoder's output in the previous time step INLINEFORM0 , the hidden layer vector of the decoder in the current timestep INLINEFORM1 and the context vector from the attention mechanism INLINEFORM2 . The context vector INLINEFORM3 for time step INLINEFORM4 is computed as a weighted sum of the output of the entire sentence using a weight parameter INLINEFORM5 : DISPLAYFORM0 \nwhere INLINEFORM0 is the number of tokens in the source sentence, INLINEFORM1 refers to the value of the hidden layer of the encoder at time step INLINEFORM2 , and INLINEFORM3 is the alignment parameter. This parameter is calculated by means of a feed forward neural network to ensure that the alignment model is free from the difficulties of contextualization of long sentences into a single vector. The feed forward network is trained along with the neural translation model to jointly improve the performance of the translation. Mathematically, DISPLAYFORM0 DISPLAYFORM1 \nwhere INLINEFORM0 is the softmax output of the result of the feedforward network, INLINEFORM1 is the hidden state value of the decoder at timestep INLINEFORM2 and INLINEFORM3 is the encoder's hidden layer annotation at timestep INLINEFORM4 . A concatenation of the forward and the reverse hidden layer parameters of the encoder is used at each step to compute the weights INLINEFORM5 for the attention mechanism. This is done to enable an overall context of the sentence, as opposed to a context of only all the previous words of the sentence for every word in consideration. Fig. FIGREF12 is the general architecture of the neural translation model without the Bidirectional LSTM encoder.\nA global attention mechanism is preferred over local attention because the differences in the structures of the languages cannot be mapped efficiently to enable lookup into the right parts of the source sentence. Using local attention mechanism with a monotonic context lookup, where the region around INLINEFORM0 source word is looked up for the prediction of the INLINEFORM1 target word, is impractical because of the structural discordance between the English and Tamil sentences (see Figs. FIGREF37 and FIGREF44 ). The use of gaussian and other such distributions to facilitate local attention would also be inefficient because the existence of various forms of translations for the same source sentence involving morphological and structural variations that don't stay uniform through the entire corpus BIBREF5 .\nThe No Peepholes (NP) variant of the LSTM cell, formulated in Greff et al. greff2015lstm is used in this experiment as it proved to give the best results amongst all the variants of an LSTM cell. It is specified by means of a gated mechanism designed to ensure that the vanishing gradient problem is prevented. LSTM maintains its hidden layer in two components, the cell vector INLINEFORM0 and the actual hidden layer output vector INLINEFORM1 . The cell vector is ensured to never reach zero by means of a weighted sum of the previous layer's cell vector INLINEFORM2 regulated by the forget gate INLINEFORM3 and an activation of the weighted sum of the input INLINEFORM4 in the current timestep INLINEFORM5 and the previous timestep's hidden layer output vector INLINEFORM6 . The combination is similarly regulated by the input gate INLINEFORM7 . The hidden layer output is determined as an activation of the cell gate, regulated by the output gate INLINEFORM8 . The interplay between these two vectors ( INLINEFORM9 and INLINEFORM10 ) at every timestep ensures that the problem of vanishing gradients doesn't occur. The three gates are also formed as a sigmoid of the weighted sum of the previous hidden layer output INLINEFORM11 and the input in the current timestep INLINEFORM12 . The output generated out of the LSTM's hidden layer is specified as a weighted softmax over the hidden layer output INLINEFORM13 . The learnable parameters of an LSTM cell are all the weights INLINEFORM14 and the biases INLINEFORM15 . DISPLAYFORM0 \nThe LSTM specified by equations 7 through 11 is the one used for the decoder of the model. The encoder uses a bidirectional RNN LSTM cell in which there are two hidden layer components INLINEFORM0 and INLINEFORM1 that contribute to the output INLINEFORM2 of each time step INLINEFORM3 . Both the components have their own sets of LSTM equations in such a way that INLINEFORM4 for every timestep is computed from the first timestep till the INLINEFORM5 token is reached and INLINEFORM6 is computed from the INLINEFORM7 timestep backwards until the first token is reached. All the five vectors of the two components are all exactly the same as the LSTM equations specified with one variation in the computation of the result. DISPLAYFORM0 \nA global attention mechanism is preferred over local attention because the differences in the structures of the languages cannot be mapped efficiently to enable lookup into the right parts of the source sentence.",

Improving body positioning will have the most benefit at the lowest cost. Because wheel spokes are continuously cutting through air as you ride, they induce drag. Spokes on wheels with less aerodynamic drag allow for the wheels to roll with less resistance. Aerodynamic wheels are generally lighter which also decreases rolling drag.",

He was born in a patrician family (senatorial class) called the Julii that claimed lineage from the Goddess Venus and the legendary Prince Aeneas of Troy. His birth in this family had already put him ahead of most others on the road to power.\n\nCaesar was smart, hard working and charming and made many friends and connections that would help him later in life. He married a relative of Gaius Marius, the dictator of Rome at the time and furthered his political connections. Though he suffered a setback when Sulla defeated Marius, Caesar was quickly able to use that to his advantage to escape a posting that required him to remain in Rome. It was important for any aspiring Consul (leader of Rome) to be seen as an effective military general who had conquered lands for Rome.\n\nCaesar's next significant position was that of Aedile where one of his primary duties were to organize games. Caesar borrowed heavily and organized lavish games so that the people of Rome would know him. Unlike other patricians, Caesar had grown up in the Subura where, at the time, the plebeians lived and knew the importance and power that could be garnered from the love of the people.\n\nThrough multiple appointments, Caesar displayed his military genius and was eventually elected Consul. He formed an alliance with two other leading figures of the time: Pompey (a decorated general) and Crassus (richest man in Rome) known now as the \"First Triumvirate\". \n\nAfter his consulship, Caesar become Governor of Gaul and eventually won a lot of territory for Rome. However, his political opponents in Rome readied a case for prosecuting him and stripping of power. Unwilling to be subject to that, Caesar gathered one of his legions and marched on Rome. His political opponents performed a tactical retreat from Rome leaving him in nominal control. He consolidated his power by winning multiple wars in Greece, Spain and Egypt eventually solidifying his hold on Rome and getting himself elected Dictator",

Early versions of this networking model were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA.\n\nThe Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to highest, the layers are the link layer, containing communication methods for data that remains within a single network segment (link); the internet layer, providing internetworking between independent networks; the transport layer, handling host-to-host communication; and the application layer, providing process-to-process data exchange for applications.\n\nThe technical standards underlying the Internet protocol suite and its constituent protocols are maintained by the Internet Engineering Task Force (IETF).

        "evidence": "Humans (Homo sapiens) are the most common and widespread species of primate in the great ape family Hominidae, and also the most common species of primate overall. Humans are broadly characterized by their bipedalism and high intelligence. Humans' large brain and resulting cognitive skills have allowed them to thrive in a variety of environments and develop complex societies and civilizations. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and rituals, each of which bolsters human society. The desire to understand and influence phenomena has motivated humanity's development of science, technology, philosophy, mythology, religion, and other conceptual frameworks.\n\nAlthough some scientists equate the term \"humans\" with all members of the genus Homo, in common usage it generally refers to Homo sapiens, the only extant member. Anatomically modern humans emerged around 300,000 years ago in Africa, evolving from Homo heidelbergensis or a similar species and migrating out of Africa, gradually replacing or interbreeding with local populations of archaic humans. For most of history, humans were nomadic hunter-gatherers. Humans began exhibiting behavioral modernity about 160,000–60,000 years ago. The Neolithic Revolution, which began in Southwest Asia around 13,000 years ago (and separately in a few other places), saw the emergence of agriculture and permanent human settlement. As populations became larger and denser, forms of governance developed within and between communities, and a number of civilizations have risen and fallen. Humans have continued to expand, with a global population of over 8 billion as of 2022.\n\nGenes and the environment influence human biological variation in visible characteristics, physiology, disease susceptibility, mental abilities, body size, and life span. Though humans vary in many traits (such as genetic predispositions and physical features), any two humans are at least 99% genetically similar. Humans are sexually dimorphic: generally, males have greater body strength and females have a higher body fat percentage. At puberty, humans develop secondary sexual characteristics. Females are capable of pregnancy, usually between puberty, at around 12 years old, and menopause, around the age of 50.\n\nHumans are omnivorous, capable of consuming a wide variety of plant and animal material, and have used fire and other forms of heat to prepare and cook food since the time of Homo erectus. Humans can survive for up to eight weeks without food and three or four days without water. Humans are generally diurnal, sleeping on average seven to nine hours per day. Childbirth is dangerous, with a high risk of complications and death. Often, both the mother and the father provide care for their children, who are helpless at birth.\n\nHumans have a large, highly developed, and complex prefrontal cortex, the region of the brain associated with higher cognition. Humans are highly intelligent, capable of episodic memory, have flexible facial expressions, self-awareness, and a theory of mind. The human mind is capable of introspection, private thought, imagination, volition, and forming views on existence. This has allowed great technological advancements and complex tool development to be possible through complex reasoning and the transmission of knowledge to subsequent generations. Language, art, and trade are defining characteristics of humans. Long-distance trade routes might have led to cultural explosions and resource distribution that gave humans an advantage over other similar species.",

Some people argue that we can model languages at the character-level BIBREF1 . For alphabetic languages such as English, where the characters are much fewer than the words, the character embeddings achieved the state-of-the-art results with much fewer parameters.\nUnfortunately, for the other languages that use non-alphabetic systems, the character vocabulary can be also large. Moreover, Chinese and Japanese, two of the most widely used non-alphabetic languages, especially contain large numbers of ideographs: hanzi of Chinese and kanji of Japanese. The character vocabulary can be as scalable as the word vocabulary (e.g., see the datasets introduced in Section SECREF11 ). Hence the conventional character embedding-based method is not able to give us a slim vocabulary on Chinese and Japanese.\nFor convenience, let us collectively call hanzi and kanji as Chinese characters. Chinese characters are ideographs composed with semantic and phonetic radicals, both of which are available for character recognition, and the semantic information may be embedded in Chinese characters by the semantic radicals BIBREF2 . Besides, though the character vocabulary is huge, the number of the radicals is much fewer. Accordingly, we explored a model that represents the Chinese characters by the sequence of the radicals.

ETL (Extract-Transform-Load) is also possible where transformation happens before the loading stage.\nData Science and Analytics is the next step in the data lifecycle.

The generator architecture is shown in Figure 1 . The Encoder first encodes the MR into input semantic elements which are then aggregated and selected by utilizing an attention-based mechanism by the Aligner. The input to the RNN Decoder at each time step is a 1-hot encoding of a token $\\textbf {w}_{t}$ and an attentive DA representation $\\textbf {d}_{t}$ . At each time step $t$ , RNN Decoder also computes how much the feature value vector $\\textbf {s}_{t-1}$ retained for the next computational steps, and adds this information to the RNN output which represents the probability distribution of the next token $\\textbf {w}_{t+1}$ .

It has a dramatically higher energy yield than corn.  It requires almost no pesticides to grow and no fertilizer.  Switchgrass actually pulls carbon out of the air and puts it into the ground through it's large root system, thus enriching the soil it grows in rather than depleting it.  Once a switchgrass plant is established it grows back naturally every year for 18 to 20 years.",

When they communicate with people, they do so to get what they need or want, such as food, affection, or play.\n\nCats use a range of communication methods such as vocal, visual, tactile and olfactory. Cats mostly meow to communicate with people, rarely with other animals. As such, the cats' communication methods have been significantly affected by domestication. Up to 21 different cat vocalizations have been studied. It is now evident that domestic cats meow more than feral cats.",
        "answer": "Cat vocalizations have been categorized according to a range of characteristics. Originally suggested by Mildred Moelk, cat sounds are often divided into three main classes:\n\nsounds produced with the mouth closed (murmurs – purring, trilling)\nsounds produced when the mouth is first opened and then gradually closed (meowing, howling, yowling)\nsounds produced with the mouth held tensely open in the same position (growls, snarls, hisses, spits, chattering, and chirping).\nIn 1944, Moelk published the first phonetic study of cat sounds. She listened very carefully to her own cats and organized their sounds into 16 phonetic patterns divided into three main categories. She also used a phonetic alphabet to transcribe or write down the different sounds. She claimed that cats had six different forms of meows to represent friendliness, confidence, dissatisfaction, anger, fear and pain. Moelk classified eight other sounds involved in mating and fighting by listening to the animals in her yard and on the street.\n\nBrown et al. categorized vocal responses of cats according to the behavioral context: during separation of kittens from mother cats, during food deprivation, during pain, prior to or during threat or attack behavior, as in disputes over territory or food, during a painful or acutely stressful experience, as in routine prophylactic injections and during kitten deprivation. Less commonly recorded calls from mature cats included purring, conspecific greeting calls or murmurs, extended vocal dialogues between cats in separate cages, \"frustration\" calls during training or extinction of conditioned responses.\n\nMiller classified vocalizations into five categories according to the sound produced: the purr, chirr, call, meow and growl/snarl/hiss.\n\nOwens et al. categorized cat vocalizations based on their acoustic structures. There are three categories: tonal sounds, pulse sounds, and broadband sounds. Tonal sounds are further categorized into groups of harmonically structured sounds or regular tonal sounds. Pulse vocalizations are separated into pulse bursts and hybrid pulse bursts with tonal endings. Broadband sounds are separated into four groups: non-tonal broadband sounds, broadband sounds with tonal beginnings, broadband sounds with short tonal elements, and broadband sounds with long tonal endings.",

        "answer": "Milly was 6 years old and ever since she could remember, fascinated by bees. Her mother called her their little apiologist. Her father called her \"honey bee.\" Her brother called her super tough because she had been stung by bees over 10 times and not once did she cry. The truth is, Milly felt like crying when she was stung, and it was not because the sting hurt. No, Milly was sad, because when a bee stings you, it dies and Milly loves bees.\n\nKnowing what you now know about Milly, it will be no surprise to you that the Jackson's came to her when they needed help. The Jackson's were Milly's neighbors, and Milly thought they were very cool. First off, they loved animals. Including 3 kids, 2 dogs, 2 cats, and 12 little silver fish that sparkled in this huge fishbowl. They dressed colorfully, they organized street-wide garage sales, and every few weeks, they invited Milly and her brother over to watch movies in their backyard that they projected off the side of their garage. \n\nThe Jackson's were not the type of people to worry about much, but on this day, they appeared very concerned. When Milly opened the door after she heard the doorbell ring, their they all were, Thomas and Lauren (the parents), Amber, Jade, Hugo (the kids), Bosko and Roscoe (the dogs), Felix and Helix (the cats), and sparkles (all of the fish were named sparkle because you couldn't tell them apart) in their fishbowl. Amber spoke up, \"Milly, we need your help, it's an emergency.\" Jade continued, \"There are bees everywhere!\" Hugo finished, \"At least Dad and Roscoe are allergic to bee stings, so we just grabbed everyone and ran!\"\n\nMilly's eyes darted between each of the people and pets in front of her. She could see and sense the fear in them. They did not know that there was nothing to fear, Milly the little apiologist was here. Milly took a deep breath, and calmly said, \"Lead me to them.\" Thomas said, \"Thank you Milly, we think they are coming out of the garage, but we're not sure\", as they started to walk next door. \n\nStepping through the grass, you could start to hear what the Jackson's were talking about. With each step, a droning buzz sound got closer. As Milly stepped off the lawn and onto the Jackson's driveway the buzzing went up a few decibels. She started to see them. Little movements in every direction - coming from the garage, going to the garage, bouncing off the windows of the car, hovering above the buffet of colorful flowers in the planters hanging on the side of the back deck. To some it might look chaotic, but to Milly, it was amazing. \n\nThe Jackson’s stayed back, near the start of the driveway, holding their collective breaths, as Milly walked right into the swarms' midst. Milly’s tie-dye shirt was bright pink and yellow, and had the words, “Flower Power” written on the front in bold, bubbly letters. It attracted a lot of attention. Bees were landing all over her, as if exploring the shirt for some hidden nectar. Unbothered, Milly stood there for a minute and just listened to the buzz. She could sense that it was louder towards the garage. Milly went to the green wooden door and peered in through the window. She could not believe her eyes.\n\nThe window on the door of the Jackson’s garage was in need of a cleaning. But it was clear to Milly that something remarkable was behind this door, because she could see bees everywhere. Not just flying, but bees on the table top, the toolbox, the walls, the lights, the bicycles, they were everywhere. So many, the walls looked like they were moving. Milly opened the door and walked in, a few bees blasted out as the door opened, along with a rush of air carrying a slightly sweet fragrance. \n\nMore bees flew towards Milly, landing on her. Walking on her sleeves, hanging on to her shoe laces, getting tangled in her hair. Milly put her hand over her mouth and nose, so she could breathe without inhaling a bee. She had to keep blinking to keep the bees from obscuring her vision. She walked slowly to the table top that used to have a few tools on it, keeping a close eye on where she stepped. She started her search here, because she noticed a strange pattern in the surface movement: there was a small trail between thousands of bees on the wall behind the table top.\n\nMilly knows a lot about bees. That male bees don’t have stingers. Females and males have different body types and shapes. Females have shorter antennae, males tend to be slimmer and smaller. Milly also knows that each hive has a single queen, and that the queen likes to walk quickly amongst her hive. As she walks, the workers all around her will part in front of her, leaving a small wake behind the queen. With this in mind, Millly scanned the wall, looking for her. \n\nAnd there she is. The queen bee stands out. She’s larger in every way. The patterns on her wings are more clear. She moves where she pleases, and her workers are happy to clear a path in front of her. Milly reached out and picked her up. The buzzing in the garage got louder almost immediately. The bees near the wall, started to lift off and fly around quickly in front of Milly, who was once again holding a hand over her mouth and nose. Milly turned to face the door and began to retrace her steps back out of the garage. \n\nAs Milly took each step, more and more bees started to land on her closed hand holding the queen. Bees landed on her arm, on her shoulder, on neck, and slowly covered all of Milly’s body. Milly made it to the door, and walked out. The Jackson’s started yelling, “Milly are you OK?!” “Milly??!!!!” “Call 9-1-1!!!” Roscoe barked. Milly couldn’t hear anything over the buzzing though. The weight of the bees was unexpectedly heavy. The bees were warm too, and she could feel a tinge of perspiration on her brow.\n\nMilly headed home. She didn’t have any pets of her own, she didn’t ask for much, but she was about to make a big ask. Milly still moved slowly, as her vision was still obscured given the movement in front, above, and below her eyes. She could sense the Jackson’s kids rushing ahead of her, and shouting. Milly could feel the queen in her hand moving around, pushing at the edges between her fingers, trying to get through to her hive that was crawling all over Milly.\n\nAs she walked back across the lawn, she started to see people on the street watching her. She could see her house between blinks, and her mother and father walking towards her, with big grins on their faces. They walked right up to Milly, and spoke loudly to be heard over the buzzing. “Where are you going, my little beekeeper?” Her dad’s voice cut through the buzz. Milly just looked up at him, and over at her mom. She responded with her eyes, though blinking rapidly, those big green eyes conveyed a desire to her parents that they understood.\n\nThe two parents looked at each other and sighed, then looked back down at their daughter. “So, what are we supposed to do, get a nice box or jar for the queen?” Milly nodded, and headed through the gate to their backyard. Milly’s parents followed, along with her brother, and the Jackson’s, though Roscoe stayed wearily at the back of the group. Milly’s mother disappeared into their shed and emerged a few seconds later with a small box that had a lid with a very fine mesh. A temporary home for a queen.\n\nThe box was placed on the patio table and the group gathered around. Milly reached out and placed the queen in the box and stepped back. As she stepped away, the bees started to lift off of her, buzzing in the air, waiting to pick up the new signal of the queen’s location. Then one by one, they found her, and rapidly flew towards the box, covering the table in seconds.\n\nMilly let out a deep breath and looked at her friends and family. She dropped the hand from over her mouth, and helped a few bees that were stuck in her hair find their way out. She had the biggest smile on her face, like only a happy 6 year old can have, and she asked, “Who likes honey?”",

        "answer": "The authors use AdaGrad for training and inference in all experiments reported in this work.",
        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nWe use AdaGrad (Duchi et al., 2011) for training and inference in all experiments reported in this work.",

        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nMoreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer.",

Lucas is considered to be one of the most significant figures of the 20th-century New Hollywood movement, and a pioneer of the modern blockbuster.\n\nAfter graduating from the University of Southern California in 1967, Lucas co-founded American Zoetrope with filmmaker Francis Ford Coppola. Lucas wrote and directed THX 1138 (1971), based on his student short Electronic Labyrinth: THX 1138 4EB, which was a critical success but a financial failure. His next work as a writer-director was American Graffiti (1973), inspired by his youth in the early 1960s Modesto, California, and produced through the newly founded Lucasfilm. The film was critically and commercially successful and received five Academy Award nominations, including Best Director and Best Picture.\n\nLucas's next film, the epic space opera Star Wars (1977), had a troubled production but was a surprise hit, becoming the highest-grossing film at the time, winning six Academy Awards and sparking a cultural phenomenon. Lucas produced and co-wrote the sequels The Empire Strikes Back (1980) and Return of the Jedi (1983). With director Steven Spielberg, he created, produced, and co-wrote the Indiana Jones films Raiders of the Lost Ark (1981), The Temple of Doom (1984), The Last Crusade (1989), and The Kingdom of the Crystal Skull (2008), and only produced The Dial of Destiny (2023). Lucas is also known for his collaboration with composer John Williams, who was recommended to him by Spielberg, and with whom he has worked for all the films in both of these franchises. He also produced and wrote a variety of films and television series through Lucasfilm between the 1970s and the 2010s.\n\nIn 1997, Lucas re-released the original Star Wars trilogy as part of a Special Edition featuring several modifications; home media versions with further changes were released in 2004 and 2011. He returned to directing with a Star Wars prequel trilogy comprising Star Wars: Episode I – The Phantom Menace (1999), Episode II – Attack of the Clones (2002), and Episode III – Revenge of the Sith (2005).

        "evidence": "Datasets and Models We evaluate our adversarial attacks on different text classification datasets from tasks such as sentiment classification, subjectivity detection and question type classification. Amazon, Yelp, IMDB are sentence-level sentiment classification datasets which have been used in recent work BIBREF15 while MR BIBREF16 contains movie reviews based on sentiment polarity. MPQA BIBREF17 is a dataset for opinion polarity detection, Subj BIBREF18 for classifying a sentence as subjective or objective and TREC BIBREF19 is a dataset for question type classification.\nWe use 3 popular text classification models: word-LSTM BIBREF20, word-CNN BIBREF21 and a fine-tuned BERT BIBREF12 base-uncased classifier. For each dataset we train the model on the training data and perform the adversarial attack on the test data. For complete model details refer to Appendix.\nAs a baseline, we consider TextFooler BIBREF11 which performs synonym replacement using a fixed word embedding space BIBREF22. We only consider the top $K{=}50$ synonyms from the MLM predictions and set a threshold of 0.8 for the cosine similarity between USE based embeddings of the adversarial and input text.\nResults We perform the 4 modes of our attack and summarize the results in Table . Across datasets and models, our BAE attacks are almost always more effective than the baseline attack, achieving significant drops of 40-80% in test accuracies, with higher average semantic similarities as shown in parentheses. BAE-R+I is the strongest attack since it allows both replacement and insertion at the same token position, with just one exception. We observe a general trend that the BAE-R and BAE-I attacks often perform comparably, while the BAE-R/I and BAE-R+I attacks are much stronger. We observe that the BERT-based classifier is more robust to the BAE and TextFooler attacks than the word-LSTM and word-CNN models which can be attributed to its large size and pre-training on a large corpus.\nThe baseline attack is often stronger than the BAE-R and BAE-I attacks for the BERT based classifier. We attribute this to the shared parameter space between the BERT-MLM and the BERT classifier before fine-tuning. The predicted tokens from BERT-MLM may not drastically change the internal representations learned by the BERT classifier, hindering their ability to adversarially affect the classifier prediction.\nEffectiveness We study the effectiveness of BAE on limiting the number of R/I operations permitted on the original text. We plot the attack performance as a function of maximum $\\%$ perturbation (ratio of number of word replacements and insertions to the length of the original text) for the TREC dataset. From Figure , we clearly observe that the BAE attacks are consistently stronger than TextFooler. The classifier models are relatively robust to perturbations up to 20$\\%$, while the effectiveness saturates at 40-50$\\%$. Surprisingly, a 50$\\%$ perturbation for the TREC dataset translates to replacing or inserting just 3-4 words, due to the short text lengths.\nQualitative Examples We present adversarial examples generated by the attacks on a sentence from the IMDB and Yelp datasets in Table . BAE produces more natural looking examples than TextFooler as tokens predicted by the BERT-MLM fit well in the sentence context. TextFooler tends to replace words with complex synonyms, which can be easily detected. Moreover, BAE's additional degree of freedom to insert tokens allows for a successful attack with fewer perturbations.\nHuman Evaluation We consider successful adversarial examples generated from the Amazon and IMDB datasets and verify their sentiment and grammatical correctness. Human evaluators annotated the sentiment and the grammar (Likert scale of 1-5) of randomly shuffled adversarial examples and original texts. From Table , BAE and TextFooler have inferior accuracies compared to the Original, showing they are not always perfect. However, BAE has much better grammar scores, suggesting more natural looking adversarial examples.\nAblation Study We analyze the benefits of R/I operations in BAE in Table . From the table, the splits $\\mathbb {A}$ and $\\mathbb {B}$ are the $\\%$ of test points which compulsorily need I and R operations respectively for a successful attack. We can observe that the split $\\mathbb {A}$ is larger than $\\mathbb {B}$ thereby indicating the importance of the I operation over R. Test points in split require both R and I operations for a successful attack. Interestingly, split is largest for Subj, which is the most robust to attack (Table ) and hence needs both R/I operations. Thus, this study gives positive insights towards the importance of having the flexibility to both replace and insert words.\nRefer to the Appendix for additional results, effectiveness graphs and details of human evaluation.\nWe evaluate BAE on different text classification tasks.

        "answer": "An encoder and a recurrent decoder.",
        "evidence": "Neural Machine Translation (NMT) has shown its effectiveness in translation tasks when NMT systems perform best in recent machine translation campaigns BIBREF0 , BIBREF1 . Compared to phrase-based Statistical Machine Translation (SMT) which is basically an ensemble of different features trained and tuned separately, NMT directly modeling the translation relationship between source and target sentences. Unlike SMT, NMT does not require much linguistic information and large monolingual data to achieve good performances.\nAn NMT consists of an encoder which recursively reads and represents the whole source sentence into a context vector and a recurrent decoder which takes the context vector and its previous state to predict the next target word. It is then trained in an end-to-end fashion to learn parameters which maximizes the likelihood between the outputs and the references. Recently, attention-based NMT has been featured in most state-of-the-art systems. First introduced by BIBREF2 , attention mechanism is integrated in decoder side as feedforward layers. It allows the NMT to decide which source words should take part in the predicting process of the next target words. It helps to improve NMTs significantly. Nevertheless, since the attention mechanism is specific to a particular source sentence and the considering target word, it is also specific to particular language pairs.\nSome recent work has focused on extending the NMT framework to multilingual scenarios. By training such network using parallel corpora in number of different languages, NMT could benefit from additional information embedded in a common semantic space across languages. Basically, the proposed NMT are required to employ multiple encoders or multiple decoders to deal with multilinguality. Furthermore, in order to avoid the tight dependency of the attention mechanism to specific language pairs, they also need to modify their architecture to combine either the encoders or the attention layers. These modifications are specific to the purpose of the tasks as well. Thus, those multilingual NMTs are more complicated, much more free parameters to learn and more difficult to perform standard trainings compared to the original NMT.\nIn this paper, we introduce a unified approach to seamlessly extend the original NMT to multilingual settings. Our approach allows us to integrate any language in any side of the encoder-decoder architecture with only one encoder and one decoder for all the languages involved. Moreover, it is not necessary to do any network modification to enable attention mechanism in our NMT systems. We then apply our proprosed framework in two demanding scenarios: under-resourced translation and zero-resourced translation. The results show that bringing multilinguality to NMT helps to improve individual translations. With some insightful analyses of the results, we set our goal toward a fully multilingual NMT framework.\nThe paper starts with a detailed introduction to attention-based NMT. In Section SECREF3 , related work about multi-task NMT is reviewed. Section SECREF5 describes our proposed approach and thorough comparisons to the related work.

        "answer": "The weightless feeling from a rollercoaster is caused by gravitational force, also known as g-force. Different rollercoaster elements lead to different types of g-force: there is positive g-force, which drives blood downwards towards the feet, and negative g-force, which drives blood upwards towards the head. Negative g-force acts opposite to gravity, and it occurs when you accelerate downwards faster than free-fall. The acceleration causes you to pull out of your seat, evoking a sense of weightlessness.",

They intend to perform these experiments as part of their ongoing research.",
        "evidence": "The sentence level classification task is an imbalanced binary classification problem that we address using BERT BIBREF0. We use BERTBASE, uncased, which consists of 12 self-attention layers, and returns a 768-dimension vector that representation a sentence. So as to make use of BERT for sentence classification, we include a fully connected layer on top of the BERT self-attention layers, which classifies the sentence embedding provided by BERT into the two classes of interest (propaganda or non-propaganda).\nWe attempt to exploit various data augmentation techniques to address the problem of class imbalance. Table TABREF17 shows the results of our experiments for different data augmentation techniques when, after shuffling the training data, we train the model on 75% of the training data and test it on the remaining 25% of the training data and the development data.\nWe observe that BERT without augmentation consistently outperforms BERT with augmentation in the experiments when the model is trained on 75% of the training data and evaluated on the rest, i.e trained and evaluated on similar data, coming from the same distribution. This is consistent with observations by Wei et al. wei2019eda that contextual word embeddings do not gain from data augmentation. The fact that we shuffle the training data prior to splitting it into training and testing subsets could imply that the model is learning to associate topic words, such as `Mueller', as propaganda. However, when we perform model evaluation using the development set, which is dissimilar to the training, we observe that synonym insertion and word dropping techniques also do not bring performance gains, while random oversampling increases performance over base BERT by 4%. Synonym insertion provides results very similar to base BERT, while random deletion harms model performance producing lower scores. We believe that this could be attributed to the fact that synonym insertion and random word dropping involve the introduction of noise to the data, while oversampling does not. As we are working with natural language data, this type of noise can in fact change the meaning of the sentence. Oversampling on the other hand purely increases the importance of the minority class by repeating training on the unchanged instances.\nSo as to better understand the aspects of oversampling that contribute to these gains, we perform a class-wise performance analysis of BERT with/without oversampling. The results of these experiments (Table TABREF18) show that oversampling increases the overall recall while maintaining precision. This is achieved by significantly improving the recall of the minority class (propaganda) at the cost of the recall of the majority class.\nSo far we have been able to establish that a) the training and test sets are dissimilar, thus requiring us to generalise our model, b) oversampling provides a method of generalisation, and c) oversampling does this while maintaining recall on the minority (and thus more interesting) class.\nGiven this we explore alternative methods of increasing minority class recall without a significant drop in precision. One such method is cost-sensitive classification, which differs from random oversampling in that it provides a more continuous-valued and consistent method of weighting samples of imbalanced training data; for example, random oversampling will inevitably emphasise some training instances at the expense of others. We detail our methods of using cost-sensitive classification in the next section. Further experiments with oversampling might have provided insights into the relationships between these methods, which we leave for future exploration.\nOne of the major setbacks to our method for identifying sentence fragments was the loss of training data as a result of randomly picking one label when the same fragment had multiple labels.

        "question": "What do the terms direct current (DC) or alternating current (AC) mean?",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

        "question": "What was constructed to quantify the improvement provided by Doc2Vec?",
        "answer": "A MST-kNN graph.",
        "evidence": "Our framework consists of a series of steps for which there are choices and alternatives. Although it is not possible to provide comparisons to the myriad of methods and possibilities available, we have examined quantitatively the robustness of the results to parametric and methodological choices in different steps of the framework: (i) the importance of using Doc2Vec embeddings instead of BoW vectors, (ii) the size of training corpus for Doc2Vec; (iii) the sparsity of the MST-kNN similarity graph construction. We have also carried out quantitative comparisons to other methods, including: (i) LDA-BoW, and (ii) clustering with other community detection methods. We provide a brief summary here and additional material in the SI.\nThe use of fixed-sized vector embeddings (Doc2Vec) instead of standard bag of words (BoW) is an integral part of our pipeline. Doc2Vec produces lower dimensional vector representations (as compared to BoW) with higher semantic and syntactic content. It has been reported that Doc2Vec outperforms BoW representations in practical benchmarks of semantic similarity, as well as being less sensitive to hyper-parameters BIBREF22 .\nTo quantify the improvement provided by Doc2Vec in our framework, we constructed a MST-kNN graph following the same steps but starting with TF-iDF vectors for each document. We then ran MS on this TF-iDF similarity graph, and compared the results to those obtained from the Doc2Vec similarity graph. Figure 7 shows that the Doc2Vec version outperforms the BoW version across all resolutions in terms of both $NMI$ and $\\widehat{PMI}$ scores.\nAs shown in Table 1 , we have tested the effect of the size of the training corpus on the Doc2Vec model. We trained Doc2Vec on two additional training sets of 1 million and 2 million records (randomly chosen from the full set of $\\sim $ 13 million records). We then followed the same procedure to construct the MST-kNN similarity graph and carried out the MS analysis. The results, presented in Figure S3 in the SI, show that the performance is affected only mildly by the size of the Doc2Vec training set.\nTo examine the effect of sparsification in the graph construction, we have studied the dependence of quality of the partitions against the number of neighbours, $k$ , in the MST-kNN graph. Our numerics, shown in Figure S4 in the SI, indicate that both the $NMI$ and $\\widehat{PMI}$ scores of the MS clusterings reach a similar level of quality for values of $k$ above 13-16, with minor improvement after that. Hence our results are robust to the choice of $k$ , provided it is not too small. Due to computational efficiency, we thus favour a relatively small $k$ , but not too small.\nWe carried out a comparison with LDA, a widely used methodology for text analysis. A key difference between standard LDA and our MS method is the fact that a different LDA model needs to be trained separately for each number of topics pre-determined by the user. To offer a comparison across the methods, We obtained five LDA models corresponding to the five MS levels we considered in detail. The results in Table 2 show that MS and LDA give partitions that are comparably similar to the hand-coded categories (as measured with $NMI$ ), with some differences depending on the scale, whereas the MS clusterings have higher topic coherence (as given by $\\widehat{PMI}$ ) across all scales.\nTo give an indication of the computational cost, we ran both methods on the same servers. Our method takes approximately 13 hours in total to compute both the Doc2Vec model on 13 million records (11 hours) and the full MS scan with 400 partitions across all resolutions (2 hours). The time required to train just the 5 LDA models on the same corpus amounts to 30 hours (with timings ranging from $\\sim $ 2 hours for the 3 topic LDA model to 12.5 hours for the 44 topic LDA model).\nThis comparison also highlights the conceptual difference between our multi-scale methodology and LDA topic modelling. While LDA computes topics at a pre-determined level of resolution, our method obtains partitions at all resolutions in one sweep of the Markov time, from which relevant partitions are chosen based on their robustness. However, the MS partitions at all resolutions are available for further investigation if so needed.\nWe have used several algorithms readily available in code libraries (i.e., the iGraph module for Python) to cluster/partition the same kNN-MST graph. Figure S5 in the SI shows the comparison against several well-known partitioning methods (Modularity Optimisation BIBREF44 , InfoMap BIBREF4 , Walktrap BIBREF45 , Label Propagation BIBREF46 , and Multi-resolution Louvain BIBREF35 ) which give just one partition (or two in the case of the Louvain implementation in iGraph) into a particular number of clusters, in contrast with our multiscale MS analysis. Our results show that MS provides improved or equal results to other graph partitioning methods for both $NMI$ and $\\widehat{PMI}$ across all scales. Only for very fine resolution with more than 50 clusters, Infomap, which partitions graphs into small clique-like subgraphs BIBREF32 , BIBREF47 , provides a slightly improved $NMI$ for that particular scale. Therefore, MS allows us to find relevant, yet high quality clusterings across all scales by sweeping the Markov time parameter.\nTo quantify the improvement provided by Doc2Vec in our framework, we constructed a MST-kNN graph following the same steps but starting with TF-iDF vectors for each document.",

The user-generated texts contain high information content in the form of news, expression, or knowledge. Automatically mining information from user-generated data is unraveling a new field of research in Natural Language Processing (NLP) and has been a difficult task due to unstructured and noisy nature. In spite of the existing challenges, much research has been conducted on user-generated data in the field of information extraction, sentiment analysis, event extraction, user profiling and many more.\nAccording to Census of India, there are 22 scheduled languages and more than 100 non scheduled languages in India. There are 462 million internet users in India and most people know more than one language. They express their feelings or emotions using more than one languages, thus generating a new code-mixed/code-switched language. The problem of code-mixing and code-switching are well studied in the field of NLP BIBREF0 , BIBREF1 . Information extraction from Indian internet user-generated texts become more difficult due to this multilingual nature. Much research has been conducted in this field such as language identification BIBREF2 , BIBREF3 , part-of-speech tagging BIBREF4 . Joshi et al. JoshiPSV16 have performed sentiment analysis in Hindi-English (HI-EN) code-mixed data and almost no work exists on sentiment analysis of Bengali-English (BN-EN) code-mixed texts. The Sentiment Analysis of Indian Language (Code-Mixed) (SAIL _Code-Mixed) is a shared task at ICON-2017. Two most popular code-mixed languages namely Hindi and Bengali mixed with English were considered for the sentiment identification task. A total of 40 participants registered for the shared task and only nine teams have submitted their predicted outputs. Out of nine unique submitted systems for evaluation, eight teams submitted fourteen runs for HI-EN dataset whereas seven teams submitted nine runs for BN-EN dataset. The training and test dataset were provided after annotating the languages and sentiment (positive, negative, and neutral) tags. The language tags were automatically annotated with the help of different dictionaries whereas the sentiment tags were manually annotated.

We use an NMT model similar to that used by Sutskever et al. Sutskever14, which uses a deep long short-term memories (LSTM) BIBREF7 to encode the input sentence and a separate deep LSTM to output the translation. We train the NMT model on a bilingual corpus in which the technical terms are replaced with technical term tokens; this allows it to translate most of the source sentences except technical terms. Similar to Sutskever et al. Sutskever14, we use it as a decoder to translate source sentences with technical term tokens and replace the tokens with technical term translations using statistical machine translation (SMT). We also use it to rerank the 1,000-best SMT translations on the basis of the average of the SMT and NMT scores of the translated sentences that have been rescored with the technical term tokens. Our experiments on Japanese-Chinese patent sentences show that our proposed NMT system achieves a substantial improvement of up to 3.1 BLEU points and 2.3 RIBES points over a traditional SMT system and an improvement of approximately 0.6 BLEU points and 0.8 RIBES points over an equivalent NMT system without our proposed technique.\nOne important difference between our NMT model and the one used by Sutskever et al. Sutskever14 is that we added an attention mechanism. Recently, Bahdanau et al. Bahdanau15 proposed an attention mechanism, a form of random access memory, to help NMT cope with long input sequences. Luong et al. Luong15b proposed an attention mechanism for different scoring functions in order to compare the source and target hidden states as well as different strategies for placing the attention. In this paper, we utilize the attention mechanism proposed by Bahdanau et al. Bahdanau15, wherein each output target word is predicted on the basis of not only a recurrent hidden state and the previously predicted word but also a context vector computed as the weighted sum of the hidden states.\nAccording to the approach proposed by Dong et al. Dong15b, we identify Japanese-Chinese technical term pairs using an SMT phrase translation table. Given a parallel sentence pair $\\langle S_J, S_C\\rangle $ containing a Japanese technical term $t_J$ , the Chinese translation candidates collected from the phrase translation table are matched against the Chinese sentence $S_C$ of the parallel sentence pair. Of those found in $S_C$ , $t_C$ with the largest translation probability $P(t_C\\mid t_J)$ is selected, and the bilingual technical term pair $\\langle t_J,t_C\\rangle $ is identified.\nFor the Japanese technical terms whose Chinese translations are not included in the results of Step UID11 , we then use an approach based on SMT word alignment. Given a parallel sentence pair $\\langle S_J, S_C\\rangle $ containing a Japanese technical term $t_J$ , a sequence of Chinese words is selected using SMT word alignment, and we use the Chinese translation $t_C$ for the Japanese technical term $t_J$ .\nFigure 3 illustrates the procedure for producing Chinese translations via decoding the Japanese sentence using the method proposed in this paper. In the step 1 of Figure 3 , when given an input Japanese sentence, we first automatically extract the technical terms and replace them with the technical term tokens “ $TT_{i}$ ” ( $i=1,2,\\ldots $ ). Consequently, we have an input sentence in which the technical term tokens “ $TT_{i}$ ” ( $i=1,2,\\ldots $ ) represent the positions of the technical terms and a list of extracted Japanese technical terms. Next, as shown in the step 2-N of Figure 3 , the source Japanese sentence with technical term tokens is translated using the NMT model trained according to the procedure described in Section \"NMT Training after Replacing Technical Term Pairs with Tokens\" , whereas the extracted Japanese technical terms are translated using an SMT phrase translation table in the step 2-S of Figure 3 . Finally, in the step 3, we replace the technical term tokens “ $TT_{i}$ ” ( $i=1,2,\\ldots $ ) of the sentence translation with SMT the technical term translations.\nFLOAT SELECTED: Figure 2: NMT training after replacing technical term pairs with technical term tokens “TTi” (i = 1, 2, . . .)\nFLOAT SELECTED: Figure 3: NMT decoding with technical term tokens “TTi” (i = 1, 2, . . .) and SMT technical term translation\nFLOAT SELECTED: Figure 4: NMT rescoring of 1,000-best SMT translations with technical term tokens “TTi” (i = 1, 2, . . .)\nWe use an NMT model similar to that used by Sutskever et al. Sutskever14, which uses a deep long short-term memories (LSTM) BIBREF7 to encode the input sentence and a separate deep LSTM to output the translation. We train the NMT model on a bilingual corpus in which the technical terms are replaced with technical term tokens; this allows it to translate most of the source sentences except technical terms. Similar to Sutskever et al. Sutskever14, we use it as a decoder to translate source sentences with technical term tokens and replace the tokens with technical term translations using statistical machine translation (SMT). We also use it to rerank the 1,000-best SMT translations on the basis of the average of the SMT and NMT scores of the translated sentences that have been rescored with the technical term tokens.\nIn this paper, we utilize the attention mechanism proposed by Bahdanau et al. Bahdanau15, wherein each output target word is predicted on the basis of not only a recurrent hidden state and the previously predicted word but also a context vector computed as the weighted sum of the hidden states.\nAccording to the approach proposed by Dong et al. Dong15b, we identify Japanese-Chinese technical term pairs using an SMT phrase translation table.\nFor the Japanese technical terms whose Chinese translations are not included in the results of Step UID11 , we then use an approach based on SMT word alignment\nFinally, in the step 3, we replace the technical term tokens “ $TT_{i}$ ” ( $i=1,2,\\ldots $ ) of the sentence translation with SMT the technical term translations.",

        "question": "What are the semantics of SLASH and the actual benefits of embracing PCs into the framework?",
        "answer": "We are happy to hear our work to be well written. While the benefits of Neuro-Symbolic approaches are becoming more well known recently (but are not as apparent in all parts of the AI community), we emphasize the ability of SLASH to combine neural, logical and truly tractable probabilistic modules within a unifying framework and via a single optimization procedure. We believe we have presented the benefits of PCs in Probabilistic Logic Programming over several claims. Firstly, via NPPs with PCs we have a much larger set of probabilistic queries, such as P(X, C) and P(C|X) in addition to P(X|C), see pp. 4 - 5. Particularly, we emphasize that neural predicates as used in previous works can in principle only handle queries of the form P(X|C), p. 4. With our results on computation time, we wished to show that this advantage of tractable probabilistic inference comes at the same or fewer costs as previous DPPLs, p. 7. Next, with our experiments on missing data, we explicitly show the practical advantages of PCs, pp. 7-8. Specifically, simply by using the marginalization abilities of PCs, we can handle the case of missing data out of the box. Lastly, with PC we are getting a generative model, which comes in handy in case of small data sets and/or image generation.",
        "evidence": "Previous DPPLs, DeepProbLog and NeurASP, introduced the Neural Predicate as an annotated-disjunction or as a propositional atom, respectively, to acquire conditional class probabilities, P (C|X), via the softmax function at the output of an arbitrary DNN. As mentioned in the introduction, this approach has certain limitations concerning inference capabilities. To resolve this issue, we introduce Neural-Probabilisitic Predicates (NPPs).\nFormally, we denote with\na Neural-Probabilistic Predicate h. Thereby, (i) npp is a reserved word to label an NPP, (ii) h a symbolic name of either a PC, NN or a joint of a PC and NN (cf. Fig.), e.g., color_attr is the name of an NPP of Fig.. Additionally, (iii) x denotes a \"term\" and (iv) v 1 , . . . , v n are placeholders for each of the n possible outcomes of h. For example, the placeholders for color_attr are the color attributes of an object (Red, Blue, Green, etc.).\nAn NPP abbreviates an arithmetic literal of the form c = v with c ∈ {h(x)} and v ∈ {v 1 , . . . , v n }. Furthermore, we denote with Π npp a set of NPPs of the form stated in (Eq. 1) and r npp the set of all rules c = v of one NPP, which denotes the possible outcomes, obtained from an NPP in Π npp , e.g. r color_attr = {c = Red, c = Blue, c = Green, ...} for the example depicted in Fig..\nRules of the form npp (h(x), [v 1 , . . . , v n ]) ← Body are used as an abbreviation for application to multiple entities, e.g. multiple slots for the task of set prediction (cf. Fig.). Hereby, Body of the rule is identified by (tautology, true) or ⊥ (contradiction, false) during grounding. Rules of the form Head ← Body with r npp appearing in Head are prohibited for Π npp .\nIn this work, we largely make use of NPPs that contain probabilistic circuits (specifically SPNs) which allow for tractable density estimation and modelling of joint probabilities. In this way, it is possible to answer a much richer set of probabilistic queries, i.e. P (X, C), P (X|C) and P (C|X).\nIn addition to this, we introduce the arguably more interesting type of NPP that combines a neural module with a PC. Hereby, the neural module learns to map the raw input data into an optimal latent representation, e.g. object-based slot representations. The PC, in turn, learns to model the joint distribution of these latent variables and produces the final probability estimates. This type of NPP nicely combines the representational power of neural networks with the advantages of PCs in probability estimation and query flexibility.\nFor making the different probabilistic queries distinguishable in a SLASH program, we introduce the following notation. We denote a given variable with + and the query variable with −. E.g., within the running example of set prediction (cf. Fig.), with the query color_attr(+X, −C) one is asking for P (C|X). Similarly, with color_attr(−X, +C) one is asking for P (X|C) and, finally, with color_attr(−X, −C) for P (X, C).\nTo summarize, an NPP can consist of neural and/or probabilistic modules and produces querydependent probability estimates. Due to the flexibility of its definition, the term NPP contains the predicates of previous works, but also more interesting predicates discussed above. The specific \"flavor\" of an NPP should be chosen depending on what type of probability estimation is required. Lastly, NPPs have the unified loss function of the negative log-likelihood:\n(2) whereby we are assuming the data to be i.i.d., ground truth x i to be the all-ones vector, ξ to be the parameters of the NPP and P (X,C) ξ are the predictions xi obtained from the PC encoded in the NPP.\nThe advantage of SLASH lies in the efficient integration of neural, probabilistic and symbolic computations. To emphasize this, we conduct a variety of experimental evaluations.\nExperimental Details. We use two benchmark data sets, namely for the task of MNIST-Addition and a variant of the ShapeWorld data set for For ShapeWorld experiments, we generate a data set we refer to as ShapeWorld4. Images of ShapeWorld4 contain between one and four objects, with each object consisting of four attributes: a color (red, blue, green, gray, brown, magenta, cyan or yellow), a shade (bright, or dark), a shape (circle, triangle or square) and a size (small or big). Thus, each object can be created from 84 different combinations of attributes. Fig. depicts an example image.\nWe measure performance via classification accuracies in the MNIST-Addition task. In our Shape-World4 experiments, we present the average precision. We refer to appendix B for the SLASH programs and queries of each experiment, and appendix C for a detailed description of hyperparameters and further details.\nEvaluation 1: SLASH outperforms SOTA DPPLs in MNIST-Addition. The task of MNIST-Addition is to predict the sum of two MNIST digits, presented only as raw images. During test time, however, a model should classify the images directly. Thus, although a model does not receive explicit information about the depicted digits, it must learn to identify digits via indirect feedback on the sum prediction.\nWe compare the test accuracy after convergence between the three DPPLs: DeepProbLog, NeurASP and SLASH, using a probabilistic circuit (PC) or a deep neural network (DNN) as NPP. Notably, the DNN used in SLASH (DNN) is the LeNet5 model of DeepProbLog and NeurASP. We note that when using the PC as NPP, we have also extracted conditional class probabilities P (C|X), by marginalizing the class variables C to acquire the normalization constant P (X) from the joint P (X, C), and calculating P (X|C).\nThe results can be seen in Tab. 1a. We observe that training SLASH with a DNN NPP produces SOTA accuracies compared to DeepProbLog and NeurASP, confirming that SLASH's batch-wise loss computation leads to improved performances. We further observe that the test accuracy of SLASH with a PC NPP is slightly below the other DPPLs, however we argue that this may be since a PC, in comparison to a DNN, is learning a true mixture density rather than just conditional probabilities. The advantages of doing so will be investigated in the next experiments. Note that, optimal architecture search for PCs, e.g. for computer vision, is an open research question.These evaluations show SLASH's advantages on the benchmark MNIST-Addition task. Additional benefits will be made clear in the following experiments.\nEvaluation 2: Handling Missing Data with SLASH. SLASH offers the advantage of its flexibility to use various kinds of NPPs. Thus, in comparison to previous DPPLs, one can easily integrate NPPs into SLASH that perform joint probability estimation. For this evaluation, we consider the task of MNIST-Addition with missing data. We trained SLASH (PC) and DeepProbLog with the MNIST-Addition task with images in which a percentage of pixels per image has been removed. It is important to mention here that whereas DeepProbLog handles the missing data simply as background pixels, SLASH (PC) specifically models the missing data as uncertain data by marginalizing the denoted pixels at inference time. We use DeepProbLog here representative of DPPLs without true density estimation. The results can be seen in Tab. 1b for 50%, 80%, 90% and 97% missing pixels per image. We observe that at 50%, DeepProbLog and SLASH produce almost equal accuracies. With 80% percent missing pixels, there is a substantial difference in the ability of the two DPPLs to correctly classify images, with SLASH being very stable. By further increasing the percentage of missing pixels, this difference becomes even more substantial with SLASH still reaching a 82% test accuracy even when 97% of the pixels per image are missing, whereas DeepProbLog degrades to an average of 32% test accuracy. We further note that SLASH, in comparison to DeepProbLog, produces largely reduced standard deviations over runs.\nThus, by utilizing the power of true density estimation SLASH, with an appropriate NPP, can produce more robust results in comparison to other DPPLs. Further, we refer to Appendix D, which contains results of additional experiments where training is performed with the full MNIST data set whereas only the test set entails different rates of missing pixels.\nEvaluation 3: Improved Concept Learning via SLASH. We show that SLASH can be very effective for the complex task of set prediction, which previous DPPLs have not tackled. We revert to the ShapeWorld4 data set for this setting. For set prediction, a model is trained to predict the discrete attributes of a set of objects in an image (cf. Fig. for an example ShapeWorld4 image). The difficulty for the model lies therein that it must match an unordered set of corresponding attributes (with varying number of entities over samples) with its internal representations of the image.\nThe slot attention module introduced by allows for an attractive object-centric approach to this task. Specifically, this module represents a pluggable, differentiable module that can be easily added to any architecture and, through a competitive softmax-based attention mechanism, can enforce the binding of specific parts of a latent representation into permutation-invariant, taskspecific vectors, called slots.\nIn our experiments, we wish to show that by adding logical constraints to the training setting, one can improve the overall performances and generalization properties of such a model. For this, we train SLASH with NPPs as depicted in Fig. consisting of a shared slot encoder and separate PCs, each modelling the mixture of latent slot variables and the attributes of one category, e.g. color.\nFor ShapeWorld4, we thereby have altogether four NPPs. SLASH is trained via queries of the kind exemplified in Fig. in the Appendix. We refer to this configuration as SLASH Attention.\nWe compare SLASH Attention to a baseline slot attention encoder using an MLP and Hungarian loss for predicting the object properties from the slot encodings as in. The results of these experiments can be found in Fig. (top). We observe that the average precision after convergence on the held-out test set with SLASH Attention is greatly improved to that of the baseline model. Additionally, in Fig. we observe that SLASH Attention reaches the average precision value of the baseline model in much fewer number of epochs. Thus, we can summarize that adding logical knowledge in the training procedure via SLASH can greatly improve the capabilities of a neural module for set prediction.\nEvaluation 4: Improved Compositional Generalization with SLASH. To test the hypothesis that SLASH Attention possesses improved generalization properties in comparison to the baseline model, we ran experiments on a variant of ShapeWorld4 similar to the CLEVR Compositional Generalization Test (CoGenT). The goal of CoGenT is to investigate a model's ability to handle novel combinations of attributes that were not seen during training.\nFor this purpose, we established two conditions within a ShapeWorld4 CoGenT data set: Condition (A) -the training and test data set contains squares with the colors gray, blue, brown, or yellow, triangles with the colors red, green, magenta, or cyan and circles of all colors. Condition (B) -the training set is as in Condition (A). However, the test set contains squares with the colors red, green, magenta, or cyan, triangles with the colors gray, blue, brown, or yellow and circles of all colors. The goal is to investigate how well a model can generalize that, e.g., also squares can have the color red, although never having seen evidence for this during training.\nThe resulting average precision test scores are presented in Fig. (bottom). We observe that, even though the SLASH Program used for this experiment was not explicitly written to handle composition generalization, SLASH Attention shows greatly improved generalization capabilities. This can be seen in the approx. 13% higher average precision scores on the Condition (B) test set in comparison to the baseline model. Importantly, this trend still holds even when subtracting the higher precision scores observed in Condition (A).\nTo summarize our findings from the experiments on set prediction: we observe that adding prior knowledge in the form of logical constraints via SLASH can greatly improve a neural module in terms of performance and generalizability. On a side note: training neural networks for novel tasks, often involves defining explicit loss functions, e.g. Hungarian loss for set prediction. In contrast with SLASH, no matter the choice of NPP and underlying task, the training loss remains the same. Task-related requirements simply need to be added as lines of code to the SLASH program. This additionally highlights SLASH's versatility and flexibility.\nIn this work, we largely make use of NPPs that contain probabilistic circuits (specifically SPNs) which allow for tractable density estimation and modelling of joint probabilities. In this way, it is possible to answer a much richer set of probabilistic queries, i.e. P(X, C), P(X|C) and P(C|X). In addition to this, we introduce the arguably more interesting type of NPP that combines a neural module with a PC. Hereby, the neural module learns to map the raw input data into an optimal latent representation, e.g. object-based slot representations. The PC, in turn, learns to model the joint distribution of these latent variables and produces the final probability estimates. This type of NPP nicely combines the representational power of neural networks with the advantages of PCs in probability estimation and query flexibility.****We further observe that the test accuracy of SLASH with a PC NPP is slightly below the other DPPLs, however we argue that this may be since a PC, in comparison to a DNN, is learning a true mixture density rather than just conditional probabilities.****For those experiments using NPPs with PC we have used Einsum Networks (EiNets) for implementing the probabilistic circuits. EiNets are a novel implementation design for SPNs introduced by Peharz et al. (2020) that minimize the issue of computational costs that initial SPNs had suffered. This is accomplished by combining several arithmetic operations via a single monolithic einsum-operation.****These results indicate that the conclusions, drawn in the main part of our work, remain true also in this setting of handling missing data.",

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nThrough human evaluation, we show that BAE yields adversarial examples with improved grammaticality and semantic coherence.",

Western films were popular for this time. Considered a lost film, a print was found in the State Film Archives of the Soviet Union, which donated it to the Museum of Modern Art in 1969. The film was screened to the public, for the first time since its rediscovery, on March 24 and 25, 1969. Scarlet Days was shown alongside another missing film, A Romance of Happy Valley, at the Museum of Modern Art's auditorium with titles still printed in Russian. English titles were later created by the Department of Film at the Museum of Modern Art.",

        "evidence": "Associative reinforcement learning\nAssociative reinforcement learning tasks combine facets of stochastic learning automata tasks and supervised learning pattern classification tasks. In associative reinforcement learning tasks, the learning system interacts in a closed loop with its environment.\n\nDeep reinforcement learning\nThis approach extends reinforcement learning by using a deep neural network and without explicitly designing the state space. The work on learning ATARI games by Google DeepMind increased attention to deep reinforcement learning or end-to-end reinforcement learning.\n\nAdversarial deep reinforcement learning\nAdversarial deep reinforcement learning is an active area of research in reinforcement learning focusing on vulnerabilities of learned policies. In this research area some studies initially showed that reinforcement learning policies are susceptible to imperceptible adversarial manipulations. While some methods have been proposed to overcome these susceptibilities, in the most recent studies it has been shown that these proposed solutions are far from providing an accurate representation of current vulnerabilities of deep reinforcement learning policies.\n\nFuzzy reinforcement learning\nBy introducing fuzzy inference in RL, approximating the state-action value function with fuzzy rules in continuous space becomes possible. The IF - THEN form of fuzzy rules make this approach suitable for expressing the results in a form close to natural language. Extending FRL with Fuzzy Rule Interpolation  allows the use of reduced size sparse fuzzy rule-bases to emphasize cardinal rules (most important state-action values).\n\nInverse reinforcement learning\nIn inverse reinforcement learning (IRL), no reward function is given. Instead, the reward function is inferred given an observed behavior from an expert. The idea is to mimic observed behavior, which is often optimal or close to optimal.\n\nSafe reinforcement learning\nSafe reinforcement learning (SRL) can be defined as the process of learning policies that maximize the expectation of the return in problems in which it is important to ensure reasonable system performance and/or respect safety constraints during the learning and/or deployment processes.",
        "answer": "Reinforcement Learning is an area of Machine Learning that works in a problem space or environment where the agent or Reinforcement Learning algorithm, uses an understanding of the past test results and the potential paths through the environment to calculate a policy that solves for the goal of a maximized reward.\n\nGiven the variety of environments that RL can operate in, there are a range of approaches that the agent can take and are broadly categarized as six different approaches:\n1. Associated RL - which combines traditional approaches of Machine Learning classification with the automated learning on random, or stochastically distributed results.\n2. Deep RL - which leverages traditional deep neural networks but allows for flexibility and a lack of pre-defined layers and the state space.\n3. Adversarial Deep RL - where end results are compared using vulnerabilities in state stored in Deep Neural Networks and attempts to find weaknesses in these models.\n4. Fuzzy RL - which leverages a near natural language definition of if-then fuzzy rules which determine the calculation of the value of a result.\n5. Inverse RL - which removes the common reward function evaluation part of the model and instead injects a human to observe and evalutate the results.\n6. Safe RL - is an approach to defining policies that also takes into account the behavior of the agent in the envionment, such that those agent steps are reasonaable or respect safety constraints.",

For those out-of-vocabulary words we need a model that can generate pronunciations from a written form, in real time. This is why we train a grapheme-to-phoneme (g2p) model that generates a sequence of phonemes for a given word. We train the g2p model using our dictionary and compare its performance with a widely used joint-sequence g2p model, Sequitur BIBREF26. For the g2p model we are using the same architecture as for the p2g model. The only difference is input and output vocabulary. The Sequitur and our model are using the dictionary with the same train (19'898 samples), test (2'412 samples) and validation (2'212 samples) split. Additionally, we also test their performance only on the items from the Zurich and Visp dialect, because most of the samples are from this two dialects. In Table TABREF15 we show the result of the comparison of the two models. We compute the edit distance between the predicted and the true pronunciation and report the number of exact matches. In the first columns we have the result using the whole test set with all the dialects, and in the 2nd and 3rd columns we show the number of exact matches only on the samples from the test set that are from the Zurich and Visp dialect.

We conducted three different pilot studies to determine the best way of collecting questions that require inference over commonsense knowledge:\nThe most intuitive way of collecting reading comprehension questions is to show texts to workers and let them formulate questions and answers on the texts, which is what we tried internally in a first pilot. Since our focus is to provide an evaluation framework for inference over commonsense knowledge, we manually assessed the number of questions that indeed require common sense knowledge. We found too many questions and answers collected in this manner to be lexically close to the text.\nIn a second pilot, we investigated the option to take the questions collected for one text and show them as questions for another text of the same scenario. While this method resulted in a larger number of questions that required inference, we found the majority of questions to not make sense at all when paired with another text. Many questions were specific to a text (and not to a scenario), requiring details that could not be answered from other texts. Since the two previous pilot setups resulted in questions that centered around the texts themselves, we decided for a third pilot to not show workers any specific texts at all. Instead, we asked for questions that centered around a specific script scenario (e.g. eating in a restaurant). We found this mode of collection to result in questions that have the right level of specificity for our purposes: namely, questions that are related to a scenario and that can be answered from different texts (about that scenario), but for which a text does not need to provide the answer explicitly.\nThe next section will describe the mode of collection chosen for the final dataset, based on the third pilot, in more detail.\nThe most intuitive way of collecting reading comprehension questions is to show texts to workers and let them formulate questions and answers on the texts, which is what we tried internally in a first pilot.",

Jars of peanut utter suggest a serving size as 2 tablespoons, which, when applied to the critical soft white bread, may prove too much to hold and cause soak through or tearing of the bread. We think 1.5 tablespoons is the proper amount to ensure there is coverage of the bread slice to the crust without compromising the integrity of the bread. Jelly application is even more precarious, as it holds more fluid and can soak through the bread quicker; equally, jelly has a tendency to congeal. To ensure proper application, heat the jar of jelly closer to room temperature if refrigerated, then apply using a clean butter knife or small spatula. Again, one must ensure it reaches to the crust and is evenly distributed. Once you have complete coverage of peanut butter on one slice and jelly on the other, place the peanut butter side of the first slice on top of the upward-facing jelly slice.

Following garg2012unsupervised, we set the number of PRs to 2 (excluding INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ), and SRs to 21-2=19. Table TABREF27 shows the results.\nIn the first setting (Line 1), we train and test the monolingual model on the CoNLL data. We observe significant improvements in F1 score over the Baseline (Line 0) in both languages. Using the CoNLL 2009 dataset alone, titovcrosslingual report an F1 score of 80.9% (PU=86.8%, CO=75.7%) for German. Thus, our monolingual model outperforms their monolingual model in German. For English, they report an F1 score of 83.6% (PU=87.5%, CO=80.1%), but note that our English results are not directly comparable to theirs due to differences argument identification, as discussed in section SECREF25 . As their argument identification score is lower, perhaps their system is discarding “difficult” arguments which leads to a higher clustering score.\nIn the second setting (Line 2), we use the additional monolingual Europarl (EP) data for training. We get equivalent results in English and a significant improvement in German compared to our previous setting (Line 1). The German dataset in CoNLL is quite small and benefits from the additional EP training data. In contrast, the English model is already quite good due to a relatively big dataset from CoNLL, and good accuracy syntactic parsers. Unfortunately, titovcrosslingual do not report results with this setting.\nThe third setting (Line 3) gives the results of our multilingual model, which adds the word alignments in the EP data. Comparing with Line 2, we get non-significant improvements in both languages. titovcrosslingual obtain an F1 score of 82.7% (PU=85.0%, CO=80.6%) for German, and 83.7% (PU=86.8%, CO=80.7%) for English. Thus, for German, our multilingual Bayesian model is able to capture the cross-lingual patterns at least as well as the external penalty term in BIBREF6 . We cannot compare the English results unfortunately due to differences in argument identification.\nWe also compared monolingual and bilingual training data using a setting that emulates the standard supervised setup of separate training and test data sets. We train only on the EP dataset and test on the CoNLL dataset. Lines 4 and 5 of Table TABREF27 give the results. The multilingual model obtains small improvements in both languages, which confirms the results from the standard unsupervised setup, comparing lines 2 to 3.\nThese results indicate that little information can be learned about semantic roles from this parallel data setup. One possible explanation for this result is that the setup itself is inadequate. Given the definition of aligned arguments, only 8% of English arguments and 17% of German arguments are aligned. This plus our experiments suggest that improving the alignment model is a necessary step to making effective use of parallel data in multilingual SRI, for example by joint modeling with SRI. We leave this exploration to future work.\nWe cannot compare the English results unfortunately due to differences in argument identification.",

In recent years, many large-scale RC datasets in English BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6 have nourished the development of numerous powerful and diverse RC models BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11. The state-of-the-art model BIBREF12 on SQuAD, one of the most widely used RC benchmarks, even surpasses human-level performance. Nonetheless, RC on languages other than English has been limited due to the absence of sufficient training data. Although some efforts have been made to create RC datasets for Chinese BIBREF13, BIBREF14 and Korean BIBREF15, it is not feasible to collect RC datasets for every language since annotation efforts to collect a new RC dataset are often far from trivial. Therefore, the setup of transfer learning, especially zero-shot learning, is of extraordinary importance.\nExisting methods BIBREF16 of cross-lingual transfer learning on RC datasets often count on machine translation (MT) to translate data from source language into target language, or vice versa. These methods may not require a well-annotated RC dataset for the target language, whereas a high-quality MT model is needed as a trade-off, which might not be available when it comes to low-resource languages.\nIn this paper, we leverage pre-trained multilingual language representation, for example, BERT learned from multilingual un-annotated sentences (multi-BERT), in cross-lingual zero-shot RC. We fine-tune multi-BERT on the training set in source language, then test the model in target language, with a number of combinations of source-target language pair to explore the cross-lingual ability of multi-BERT. Surprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese. Recent studies BIBREF17, BIBREF12, BIBREF18 show that cross-lingual language models have the ability to enable preliminary zero-shot transfer on simple natural language understanding tasks, but zero-shot transfer of RC has not been studied.

Although some efforts have been made to create RC datasets for Chinese BIBREF13, BIBREF14 and Korean BIBREF15, it is not feasible to collect RC datasets for every language since annotation efforts to collect a new RC dataset are often far from trivial. Therefore, the setup of transfer learning, especially zero-shot learning, is of extraordinary importance.\nExisting methods BIBREF16 of cross-lingual transfer learning on RC datasets often count on machine translation (MT) to translate data from source language into target language, or vice versa. These methods may not require a well-annotated RC dataset for the target language, whereas a high-quality MT model is needed as a trade-off, which might not be available when it comes to low-resource languages.\nIn this paper, we leverage pre-trained multilingual language representation, for example, BERT learned from multilingual un-annotated sentences (multi-BERT), in cross-lingual zero-shot RC. We fine-tune multi-BERT on the training set in source language, then test the model in target language, with a number of combinations of source-target language pair to explore the cross-lingual ability of multi-BERT. Surprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese. Recent studies BIBREF17, BIBREF12, BIBREF18 show that cross-lingual language models have the ability to enable preliminary zero-shot transfer on simple natural language understanding tasks, but zero-shot transfer of RC has not been studied. To our knowledge, this is the first work systematically exploring the cross-lingual transferring ability of multi-BERT on RC tasks.\nReading Comprehension (RC) has become a central task in natural language processing, with great practical value in various industries.****Surprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese.

        "evidence": "The goal of sentence simplification is to compose complex sentences into simpler ones so that they are more comprehensible and accessible, while still retaining the original information content and meaning. Sentence simplification has a number of practical applications. On one hand, it provides reading aids for people with limited language proficiency BIBREF1 , BIBREF2 , or for patients with linguistic and cognitive disabilities BIBREF3 . On the other hand, it can improve the performance of other NLP tasks BIBREF4 , BIBREF5 , BIBREF6 . Prior work has explored monolingual machine translation (MT) approaches, utilizing corpora of simplified texts, e.g., Simple English Wikipedia (SEW), and making use of statistical MT models, such as phrase-based MT (PBMT) BIBREF7 , BIBREF8 , BIBREF9 , tree-based MT (TBMT) BIBREF10 , BIBREF11 , or syntax-based MT (SBMT) BIBREF12 .\nInspired by the success of neural MT BIBREF13 , BIBREF14 , recent work has started exploring neural simplification with sequence to sequence (Seq2seq) models, also referred to as encoder-decoder models. Nisioi et al. Nisioi:17 implemented a standard LSTM-based Seq2seq model and found that they outperform PBMT, SBMT, and unsupervised lexical simplification approaches. Zhang and Lapata BIBREF15 viewed the encoder-decoder model as an agent and employed a deep reinforcement learning framework in which the reward has three components capturing key aspects of the target output: simplicity, relevance, and fluency. The common practice for Seq2seq models is to use recurrent neural networks (RNNs) with Long Short-Term Memory BIBREF16 or Gated Recurrent Unit BIBREF17 for the encoder and decoder BIBREF18 , BIBREF15 . These architectures were designed to be capable of memorizing long-term dependencies across sequences. Nevertheless, their memory is typically small and might not be enough for the simplification task, where one is confronted with long and complicated sentences. In this study, we go beyond the conventional LSTM/GRU-based Seq2seq models and propose to use a memory-augmented RNN architecture called Neural Semantic Encoders (NSE). This architecture has been shown to be effective in a wide range of NLP tasks BIBREF0 . The contribution of this paper is twofold:\n(1) First, we present a novel simplification model which is, to the best of our knowledge, the first model that use memory-augmented RNN for the task. We investigate the effectiveness of neural Seq2seq models when different neural architectures for the encoder are considered. Our experiments reveal that the NseLstm model that uses an NSE as the encoder and an LSTM as the decoder performed the best among these models, improving over strong simplification systems. (2) Second, we perform an extensive evaluation of various approaches proposed in the literature on different datasets. Results of both automatic and human evaluation show that our approach is remarkably effective for the task, significantly reducing the reading difficulty of the input, while preserving grammaticality and the original meaning. We further discuss some advantages and disadvantages of these approaches.\nWe investigate the effectiveness of neural Seq2seq models when different neural architectures for the encoder are considered.",

As one of the most valuable literary and cultural heritages of China, Chinese classical poetry is very familiar and loved by Chinese people from generation to generation.

In this paper, we propose a GPT-2 based uniformed framework for generating major types of Chinese classical poems.

On the other hand, we may realize there still exists a huge part of multimedia content not yet taken care of, i.e., the singing content or those with audio including songs. Songs are human voice carrying plenty of semantic information just as speech. It will be highly desired if the huge quantities of singing content can be similarly retrieved, browsed, summarized or comprehended by machine based on the lyrics just as speech. For example, it is highly desired if song retrieval can be achieved based on the lyrics in addition.\nSinging voice can be considered as a special type of speech with highly flexible and artistically designed prosody: the rhythm as artistically designed duration, pause and energy patterns, the melody as artistically designed pitch contours with much wider range, the lyrics as artistically authored sentences to be uttered by the singer. So transcribing lyrics from song audio is an extended version of automatic speech recognition (ASR) taking into account these differences.\nOn the other hand, singing voice and speech differ widely in both acoustic and linguistic characteristics. Singing signals are often accompanied with some extra music and harmony, which are noisy for recognition. The highly flexible pitch contours with much wider range BIBREF12 , BIBREF13 , the significantly changing phone durations in songs, including the prolonged vowels BIBREF14 , BIBREF15 over smoothly varying pitch contours, create much more problems not existing in speech. The falsetto in singing voice may be an extra type of human voice not present in normal speech. Regarding linguistic characteristics BIBREF16 , BIBREF17 , word repetition and meaningless words (e.g.oh) frequently appear in the artistically authored lyrics in singing voice.\nApplying ASR technologies to singing voice has been studied for long. However, not too much work has been reported, probably because the recognition accuracy remained to be relatively low compared to the experiences for speech. But such low accuracy is actually natural considering the various difficulties caused by the significant differences between singing voice and speech. An extra major problem is probably the lack of singing voice database, which pushed the researchers to collect their own closed datasets BIBREF12 , BIBREF15 , BIBREF17 , which made it difficult to compare results from different works.\nHaving the language model learned from a data set of lyrics is definitely helpful BIBREF15 , BIBREF17 . Hosoya et al. BIBREF16 achieved this with finite state automaton. Sasou et al. BIBREF12 actually prepared a language model for each song. In order to cope with the acoustic characteristics of singing voice, Sasou et al. BIBREF12 , BIBREF14 proposed AR-HMM to take care of the high-pitched sounds and prolonged vowels, while recently Kawai et al. BIBREF15 handled the prolonged vowels by extending the vowel parts in the lexicon, both achieving good improvement. Adaptation from models trained with speech was attractive, and various approaches were compared by Mesaros el al. BIBREF18 .\nIn this paper, we wish our work can be compatible to more available singing content, therefore in the initial effort we collected about five hours of music-removed version of English songs directly from commercial singing content on YouTube. The descriptive term \"music-removed\" implies the background music have been removed somehow. Because many very impressive works were based on Japanese songs BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , the comparison is difficult. We analyzed various approaches with HMM, deep learning with data augmentation, and acoustic adaptation on fragment, song, singer, and genre levels, primarily based on fMLLR BIBREF19 . We also trained the language model with a corpus of lyrics, and modify the pronunciation lexicon and increase the transition probability of HMM for prolonged vowels.

        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nHence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension.",

Rainbow is an example of physical optical illusion caused by refraction.   \n\nPhysiological optical illusion occurs when a pattern repeats over and over again and it is too much information for the brain. This causes the brain to think the images are moving. Kinetoscope uses images to create a video using physiological optical illusion.

        "question": "Given these paragraphs about Large language models, what is an LLM?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

        "evidence": "* Equal contribution. Listing order is random.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma. More concretely, consider the English sentence: The bulls are running in Pamplona. A lemmatizer will seek to map each word to a form you may find in a dictionary—for instance, mapping running to run. This linguistic normalization is important in several downstream NLP applications, especially for highly inflected languages. Lemmatization has previously been shown to improve recall for information retrieval BIBREF0 , BIBREF1 , to aid machine translation BIBREF2 , BIBREF3 and is a core part of modern parsing systems BIBREF4 , BIBREF5 .\nHowever, the task is quite nuanced as the proper choice of the lemma is context dependent. For instance, in the sentence A running of the bulls took place in Pamplona, the word running is its own lemma, since, here, running is a noun rather than an inflected verb. Several counter-examples exist to this trend, as discussed in depth in haspelmath2013understanding. Thus, a good lemmatizer must make use of some representation of each word's sentential context. The research question in this work is, then, how do we design a lemmatization model that best extracts the morpho-syntax from the sentential context?\nRecent work BIBREF7 has presented a system that directly summarizes the sentential context using a recurrent neural network to decide how to lemmatize. As N18-1126's system currently achieves state-of-the-art results, it must implicitly learn a contextual representation that encodes the necessary morpho-syntax, as such knowledge is requisite for the task. We contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize. Indeed, to this end, we introduce a joint model for the introduction of morphology into a neural lemmatizer. A key feature of our model is its simplicity: Our contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model. However, despite the model's simplicity, it still achieves a significant improvement over the state of the art on our target task: lemmatization.\nExperimentally, our contributions are threefold. First, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora BIBREF8 . Second, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization. Finally, we provide a detailed error analysis indicating when and why morphological analysis helps lemmatization. We offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.\nOur system and pre-trained models on all languages in the latest version of the UD corpora are released at https://sigmorphon.github.io/sharedtasks/2019/task2/.\nFirst, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora.",

        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited.

        "evidence": "We explored the improvement in the monolingual model in a semi-supervised setting. To this end, we randomly selected INLINEFORM0 of the sentences in the CoNLL dataset as “supervised sentences” and the rest INLINEFORM1 were kept unsupervised. Next, we clamped the role labels of the supervised sentences using the predefined mapping from Section SECREF29 . Sampling was done on the unsupervised sentences as usual. We then measured the clustering performance using the trained parameters.\nTo access the contribution of partial supervision better, we constructed a “supervised baseline” as follows. For predicates seen in the supervised sentences, a MAP estimate of the parameters was calculated using the predefined mapping. For the unseen predicates, the standard baseline was used.\nFigures FIGREF33 and FIGREF33 show the performance variation with INLINEFORM0 . We make the following observations:\n[leftmargin=*]\nIn both languages, at around INLINEFORM0 , the supervised baseline starts outperforming the semi-supervised model, which suggests that manually labeling about 10% of the sentences is a good enough alternative to our training procedure. Note that 10% amounts to about 3.6k sentences in German and 4k in English. We noticed that the proportion of seen predicates increases dramatically as we increase the proportion of supervised sentences. At 10% supervised sentences, the model has already seen 63% of predicates in German and 44% in English. This explains to some extent why only 10% labeled sentences are enough.\nFor German, it takes about 3.5% or 1260 supervised sentences to have the same performance increase as 1.5M unlabeled sentences (Line 1 to Line 2 in Table TABREF27 ). Adding about 180 more supervised sentences also covers the benefit obtained by alignments in the multilingual model (Line 2 to Line 3 in Table TABREF27 ). There is no noticeable performance difference in English.\nWe also evaluated the performance variation on a completely unseen CoNLL test set. Since the test set is very small compared to the training set, the clustering evaluation is not as reliable.

        "question": "Why disambiguating encoders are introduced?",
        "answer": "They were introduced based on the idea that an ambiguous entity can be disambiguated using its neighboring entities.",
        "evidence": "After performing entity linking to the input text using the ELS, we receive a sequential list of linked entities, arranged based on their location in the text. We embed these entities to $d$ -dimensional vectors $E = \\lbrace e_1, e_2, ..., e_m\\rbrace $ where $e_i \\in \\mathbb {R}^d$ . Since these entities may still contain ambiguity, it is necessary to resolve them before applying them to the base model. Based on the idea that an ambiguous entity can be disambiguated using its neighboring entities, we introduce two kinds of disambiguating encoders below.\nOne way to disambiguate an entity is by using all the other entities, putting more importance to entities that are nearer. For this purpose, we employ an RNN-based model to globally disambiguate the entities. Specifically, we use BiGRU and concatenate the forward and backward hidden state vectors as the new entity vector: $\n\\overrightarrow{h}_i &= GRU(e_i, \\overrightarrow{h}_{i-1}) \\\\\n\\overleftarrow{h}_i &= GRU(e_i, \\overleftarrow{h}_{i+1}) \\\\\ne^{\\prime }_i &= [\\overrightarrow{h}_i; \\overleftarrow{h}_i] \\nonumber $ \nAnother way to disambiguate an entity is by using only the direct neighbors of the entity, putting no importance value to entities that are far. To do this, we employ a CNN-based model to locally disambiguate the entities. Specifically, we do the convolution operation using filter matrices $W_f \\in \\mathbb {R}^{h \\times d}$ with filter size $h$ to a window of $h$ words. We do this for different sizes of $h$ . This produces new feature vectors $c_{i,h}$ as shown below, where $f(.)$ is a non-linear function: $\nc_{i,h} = f([e_{i-(h-1)/2}; ...; e_{i+h(+1)/2}]^\\top W_f + b_f) \\nonumber $ \nThe convolution operation reduces the number of entities differently depending on the filter size $h$ . To prevent loss of information and to produce the same amount of feature vectors $c_{i,h}$ , we pad the entity list dynamically such that when the filter size is $h$ , the number of paddings on each side is $(h-1)/2$ . The filter size $h$ therefore refers to the number of entities used to disambiguate a middle entity. Finally, we concatenate all feature vectors of different $h$ 's for each $i$ as the new entity vector: $\ne^{\\prime }_i = [c_{i,h_1}; c_{i, h_2}; ...] \\nonumber $ \nThe question on which disambiguating encoder is better has been a debate; some argued that using only the local context is appropriate BIBREF16 while some claimed that additionally using global context also helps BIBREF17 . The RNN-based encoder is good as it smartly makes use of all entities, however it may perform bad when there are many entities as it introduces noise when using a far entity during disambiguation. The CNN-based encoder is good as it minimizes the noise by totally ignoring far entities when disambiguating, however determining the appropriate filter sizes $h$ needs engineering. Overall, we argue that when the input text is short (e.g. a sentence), both encoders perform comparably, otherwise when the input text is long (e.g. a document), the CNN-based encoder performs better.\nIt is obvious that not all entities need to be disambiguated. When a correctly linked and already adequately disambiguated entity is disambiguated again, it would make the entity very context-specific and might not be suitable for the summarization task. Our entity encoding submodule therefore uses a selective mechanism that decides whether to use the disambiguating encoder or not. This is done by introducing a selective disambiguation gate $d$ . The final entity vector $\\tilde{e}_i$ is calculated as the linear transformation of $e_i$ and $e^{\\prime }_i$ : $\ne^{\\prime }_i &= encoder(e_i) \\\\\nd &= \\sigma (W_d e^{\\prime }_i + b_d) \\\\\n\\tilde{e}_i &= d \\times f(W_x e_i + b_x) + \\\\ & \\quad (1-d) \\times f(W_y e^{\\prime }_i + b_y) \\nonumber $ \nThe full entity encoding submodule is illustrated in Figure 3 .

It is one of the older buildings in Osterville, and is a fine example of the Greek Revival with Gothic Revival elements. The church was listed on the National Register of Historic Places in 1987.\n\nDescription and history\nThe Osterville Baptist Church is set prominently in the center of Osterville on the north side of the junction of Main Street and Wianno Avenue. It is rectangular single-story wood-frame structure, with a gable roof, vinyl siding, and a brick foundation. Its exterior features a mix of Greek Revival and Gothic Revival styling, with corner paneled pilasters rising to entablatures running along the sides of the building, and lancet-arched panels above its windows. Its facade is symmetrically arranged, with a pair of entrances, each framed by sidelight windows and pilasters, with an entablature and cornice on top, and sash windows above. A single lancet-arch panel adorns the center of the gable end. The church has a two-stage square tower, with a plain first stage topped by a belfry with lancet-arched louvered openings, and a steeple above.\n\nThe church congregation was organized in 1835 as the Second Barnstable Baptist Church, and this church was dedicated in 1838, having been built on land given by Captain George Lovell. Its steeple is a reconstruction of the original, which was lost in a hurricane in 1945. The church interior was remodeled in 1889, at which time a heating system was added. Further additions have been made to the rear of the building, adding classroom, meeting, and office spaces.",

Many legal jurisdictions around the world accept this framework, including the United States and the European Union BIBREF1, BIBREF2.

Various methods have been proposed to enhance the generation quality by refining the objective function BIBREF18 , BIBREF19 or modifying the generation distribution with external information like topic BIBREF20 , sentence type BIBREF21 , emotion BIBREF22 and knowledge BIBREF23 .\nAs mentioned above, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 . Thus, reinforcement learning has been introduced to text generation tasks such as policy gradient BIBREF6 and actor-critic BIBREF24 . BIBREF17 proposed an efficient and stable approach called Reward Augmented Maximum Likelihood (RAML), which connects the log-likelihood and expected rewards to incorporate MLE training objective into RL framework.\nSince some text generation tasks have no explicit metrics to be directly optimized, adversarial training has been applied to generating discrete text samples with a discriminator to learn a proper reward. For instance, SeqGAN BIBREF7 devised a discriminator to distinguish the real data and generated samples, and a generator to maximize the reward from the discriminator via policy gradient. Other variants of GANs have been proposed to improve the generator or the discriminator. To improve the generator, MaliGAN BIBREF8 developed a normalized maximum likelihood optimization target for the generator to stably model the discrete sequences. LeakGAN BIBREF11 guided the generator with reward signals leaked from the discriminator at all generation steps to deal with long text generation task. MaskGAN BIBREF10 employed an actor-critic architecture to make the generator fill in missing text conditioned on the surrounding context, which is expected to mitigate the problem of mode collapse. As for the discriminator, RankGAN BIBREF9 replaced traditional discriminator with a ranker to learn the relative ranking information between the real texts and generated ones. Inverse reinforcement learning BIBREF12 used a trainable reward approximator as the discriminator to provide dense reward signals at each generation step. DPGAN BIBREF13 introduced a language model based discriminator and regarded cross-entropy as rewards to promote the diversity of generation results.\nThe most similar works to our model are RAML BIBREF17 and MaliGAN BIBREF8 : 1) Compared with RAML, our model adds a discriminator to learn the reward signals instead of choosing existing metrics as rewards. We believe that our model can adapt to various text generation tasks, particularly those without explicit evaluation metrics. 2) Unlike MaliGAN, we acquire samples from a fixed distribution near the real data rather than the generator's distribution, which is expected to make the training process more stable.\nThe most similar works to our model are RAML (Norouzi et al., 2016) and MaliGAN (Che et al., 2017): 1) Compared with RAML, our model adds a discriminator to learn the reward signals instead of choosing existing metrics as rewards.

        "question": "Does the 'translated semantic fingerprints' method outperform the method of 'orthographic translation'?",
        "answer": "Yes.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results.

The two main species commercially cultivated are Coffea canephora (predominantly a form known as 'robusta') and C. arabica. C. arabica, the most highly regarded species, is native to the southwestern highlands of Ethiopia and the Boma Plateau in southeastern Sudan and Mount Marsabit in northern Kenya. C. canephora is native to western and central Subsaharan Africa, from Guinea to Uganda and southern Sudan. Less popular species are C. liberica, C. stenophylla, C. mauritiana, and C. racemosa.\n\nAll coffee plants are classified in the large family Rubiaceae. They are evergreen shrubs or trees that may grow 5 m (15 ft) tall when unpruned. The leaves are dark green and glossy, usually 10–15 cm (4–6 in) long and 6 cm (2.4 in) wide, simple, entire, and opposite. Petioles of opposite leaves fuse at the base to form interpetiolar stipules, characteristic of Rubiaceae. The flowers are axillary, and clusters of fragrant white flowers bloom simultaneously. Gynoecium consists of an inferior ovary, also characteristic of Rubiaceae. The flowers are followed by oval berries of about 1.5 cm (0.6 in). When immature, they are green, and they ripen to yellow, then crimson, before turning black on drying. Each berry usually contains two seeds, but 5–10% of the berries have only one; these are called peaberries. Arabica berries ripen in six to eight months, while robusta takes nine to eleven months.\n\nCoffea arabica is predominantly self-pollinating, and as a result, the seedlings are generally uniform and vary little from their parents. In contrast, Coffea canephora, and C. liberica are self-incompatible and require outcrossing. This means that useful forms and hybrids must be propagated vegetatively. Cuttings, grafting, and budding are the usual methods of vegetative propagation. On the other hand, there is great scope for experimentation in search of potential new strains.",

Data thus structured are said to be blocked. The process of putting data into blocks is called blocking, while deblocking is the process of extracting data from blocks. Blocked data is normally stored in a data buffer, and read or written a whole block at a time. Blocking reduces the overhead and speeds up the handling of the data stream. For some devices, such as magnetic tape and CKD disk devices, blocking reduces the amount of external storage required for the data. Blocking is almost universally employed when storing data to 9-track magnetic tape, NAND flash memory, and rotating media such as floppy disks, hard disks, and optical discs.\n\nMost file systems are based on a block device, which is a level of abstraction for the hardware responsible for storing and retrieving specified blocks of data, though the block size in file systems may be a multiple of the physical block size. This leads to space inefficiency due to internal fragmentation, since file lengths are often not integer multiples of block size, and thus the last block of a file may remain partially empty. This will create slack space. Some newer file systems, such as Btrfs and FreeBSD UFS2, attempt to solve this through techniques called block suballocation and tail merging. Other file systems such as ZFS support variable block sizes.\n\nBlock storage is normally abstracted by a file system or database management system (DBMS) for use by applications and end users. The physical or logical volumes accessed via block I/O may be devices internal to a server, directly attached via SCSI or Fibre Channel, or distant devices accessed via a storage area network (SAN) using a protocol such as iSCSI, or AoE.

Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nIn the first architecture, we use LSTM (Hochreiter and Schmidhuber, 1997) for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM (Tai et al., 2015) to represent the input sentences in the form of a dependency tree.",

        "evidence": "Low dimensional word representations (embeddings) have become a key component in modern NLP systems for language modeling, parsing, sentiment classification, and many others. These embeddings are usually derived by employing the distributional hypothesis: that similar words appear in similar contexts BIBREF0 .\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix BIBREF1 . The most well-known predictive model, which has become eponymous with word embedding, is word2vec BIBREF2 . Popular counting models include PPMI-SVD BIBREF3 , GloVe BIBREF4 , and LexVec BIBREF5 .\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.\nfastText BIBREF6 addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors. This addresses both issues above as learned information is shared through the n-gram vectors and from these OOV word representations can be constructed.\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , but the method proposed here should transfer to GloVe unchanged.\nThe LexVec objective is modified such that a word's vector is the sum of all its subword vectors.\nWe compare 1) the use of n-gram subwords, like fastText, and 2) unsupervised morphemes identified using Morfessor BIBREF11 to learn whether more linguistically motivated subwords offer any advantage over simple n-grams.\nTo evaluate the impact subword information has on in-vocabulary (IV) word representations, we run intrinsic evaluations consisting of word similarity and word analogy tasks. The incorporation of subword information results in similar gains (and losses) to that of fastText over Skip-gram. Whereas incorporating n-gram subwords tends to capture more syntactic information, unsupervised morphemes better preserve semantics while also improving syntactic results. Given that intrinsic performance can correlate poorly with performance on downstream tasks BIBREF12 , we also conduct evaluation using the VecEval suite of tasks BIBREF13 , in which\nall subword models, including fastText, show no significant improvement over word-level models.\nWe verify the model's ability to represent OOV words by quantitatively evaluating nearest-neighbors.

        "evidence": "The name \"Pantheon\" is from the Ancient Greek \"Pantheion\" meaning \"of, relating to, or common to all the gods\". Cassius Dio, a Roman senator who wrote in Greek, speculated that the name comes either from the statues of many gods placed around this building, or from the resemblance of the dome to the heavens. His uncertainty strongly suggests that \"Pantheon\" (or Pantheum) was merely a nickname, not the formal name of the building. In fact, the concept of a pantheon dedicated to all the gods is questionable. The only definite pantheon recorded earlier than Agrippa's was at Antioch in Syria, though it is only mentioned by a sixth-century source. Ziegler tried to collect evidence of pantheons, but his list consists of simple dedications \"to all the gods\" or \"to the Twelve Gods\", which are not necessarily true pantheons in the sense of a temple housing a cult that literally worships all the gods.",

        "answer": "Word embedding learning.",
        "evidence": "Human-computer dialog/conversation is one of the most challenging problems in artificial intelligence. Given a user-issued utterance (called a query in this paper), the computer needs to provide a reply to the query. In early years, researchers have developed various domain-oriented dialogue systems, which are typically based on rules or templates BIBREF4 , BIBREF5 , BIBREF6 . Recently, open-domain conversation systems have attracted more and more attention in both academia and industry (e.g., XiaoBing from Microsoft and DuMi from Baidu). Due to high diversity, we can hardly design rules or templates in the open domain. Researchers have proposed information retrieval methods BIBREF7 and modern generative neural networks BIBREF8 , BIBREF9 to either search for a reply from a large conversation corpus or generate a new sentence as the reply.\nIn open-domain conversations, context information (one or a few previous utterances) is particularly important to language understanding BIBREF1 , BIBREF9 , BIBREF10 , BIBREF11 . As dialogue sentences are usually casual and short, a single utterance (e.g., “Thank you.” in Figure FIGREF2 ) does not convey much meaning, but its previous utterance (“...writing an essay”) provides useful background information of the conversation. Using such context will certainly benefit the conversation system.\nHowever, tracking all previous utterances as the context is unwise. First, commercial chat-bots usually place high demands on efficiency. In a retrieval-based system, for example, performing a standard process of candidate retrieval and re-ranking for each previous utterance may well exceed the time limit (which is very short, e.g., 500ms). Second, we observe that not all sentences in the current conversation session are equally important. The sentence “Want to take a walk?” is irrelevant to the current context, and should not be considered when the computer synthesizes the reply. Therefore, it raises the question of session segmentation in conversation systems.\nDocument segmentation for general-purpose corpora has been widely studied in NLP. For example, Hearst BIBREF12 proposes the TextTiling approach; she measures the similarity of neighboring sentences based on bag-of-words features, and performs segmentation by thresholding. However, such approaches are not tailored to the dialogue genre and may not be suitable for conversation session segmentation.\nIn this paper, we address the problem of session segmentation for open-domain conversations. We leverage the classic TextTiling approach, but enhance it with modern embedding-based similarity measures. Compared with traditional bag-of-words features, embeddings map discrete words to real-valued vectors, capturing underlying meanings in a continuous vector space; hence, it is more robust for noisy conversation corpora. Further, we propose a tailored method for word embedding learning. In traditional word embedding learning, the interaction between two words in a query and a reply is weaker than that within an utterance. We propose to combine a query and its corresponding reply as a “virtual sentence,” so that it provides a better way of modeling utterances between two agents.\nFurther, we propose a tailored method for word embedding learning.",

        "answer": "The desirable convolutional (shift-invariant) behavior is of the whole model when the task is coordinate-based regression, not particularly for the purpose of positional encoding. Since, according to the NTK results, shift-invariance is achieved given some properties of the inputs, and we are changing the inputs with the proposed encoding, we want to make sure our encoding satisfies those properties.\nInspired by your suggestion regarding (sin, 2cos), we conduct an experiment to verify whether the 1) constant norm and 2) rotation-invariant inner products properties of the encodings matter in practice. The idea is to simply multiply each encoding element by a random factor, and the results show it causes a drop in performance. Please see Appendix C.3 for details.\n",
        "evidence": "Another major difference between our method and “Gaussian 3D”, is that our encodings have constant norm and rotation-invariant inner products, thus satisfying the NTK conditions for the outputs to approximate a convolution on the manifold (shift-invariance). This is appropriate for the tasks we consider, where the relative importance between training inputs (coordinates) should not depend on their absolute position. The Gaussian encoding does not satisfy these conditions and results in a translation-invariant encoding, which is not appropriate for points on the sphere. In this section, we show the effects of intentionally breaking these two properties in our model. We sample a vector, fixed during training, from a standard normal distribution with the same dimensions as the encoding. We then replace the positional encoding by its pointwise multiplication with this vector of random factors. The resulting encoding does not have constant norm nor rotation-invariant inner products.",

Recently, a number of systems have been proposed for solving the problem using the WikiTableQuestions dataset BIBREF1 (henceforth called WTQ). This dataset consists of triples of the form INLINEFORM0 question, table, answer INLINEFORM1 where the tables are scraped from Wikipedia and questions and answers are gathered via crowdsourcing. The dataset is quite challenging, with the current best model BIBREF0 (henceforth called KDG) achieving a single model accuracy of only 43.3% . This is nonetheless a significant improvement compared to the 34.8% accuracy achieved by the previous best single model BIBREF2 .\nWe sought to analyze the source of the improvement achieved by the KDG model. The KDG paper claims that the improvement stems from certain aspects of the model architecture.\nIn this paper, we find that a large part of the improvement also stems from a certain pruning of the data used to train the model. The KDG system generates its training data using an algorithm proposed by BIBREF3 . This algorithm applies a pruning step (discussed in Section SECREF3 ) to eliminate spurious training data entries. We find that without this pruning of the training data, accuracy of the KDG model drops to 36.3%. We consider this an important finding as the pruning step not only accounts for a large fraction of the improvement in the state-of-the-art KDG model but may also be relevant to training other models. In what follows, we briefly discuss the pruning algorithm, how we identified its importance for the KDG model, and its relevance to further work.\nWe find that without this pruning of the training data, accuracy of the KDG model drops to 36.3%.",

Even more data is needed when training (source) and testing (target) data differ, as the model must be adapted on the new data to maintain accuracy. To reduce the annotation effort on new data, unsupervised domain adaptation (UDA) approaches transfer knowledge from labeled source data to unlabeled target data. Standard UDA requires simultaneous optimization on the source and target data to do so.

Such approaches reduce reliance on the source data, and can even improve accuracy, but have they made full use of the target data? Many of the model parameters are fixed or regularized toward the source parameters. We investigate whether more can be learned from target, and more accuracy gained, by not transferring the source parameters.\nWe propose on-target adaptation to unshackle the target representation from the source representation. To do so, we (1) factorize the representation from the classifier and (2) separate the source parameters from the source predictions. By factorizing the representation from the classifier, we can train the representation entirely on the target data by self-supervision. Given this on-target representation, we can then supervise a new classifier from source predictions by distillation, without transferring the source parameters. Not transferring parameters frees our target model from the constraints of the source architecture, so that we can experiment with distinct target architectures. In this way, we can even change the model size to optimize a target-specific model that is more accurate and more efficient. In contrast to prior work on adaptation, this uniquely allows for learning 100% of the target model parameters on target data, as illustrated by Figure.

We turn the source model into a teacher model by sourcefree adaptation, and then generate pseudo-labels to supervise distillation. We lastly train the student model on the teacher supervision, starting from the target representation and new classifier parameters, and repeat this teacher-student cycle by resetting the student classifier parameters between epochs. Contrastive learning has recently enabled self-supervised representations to compete with or even surpass supervised representations. We show it provides a sufficient target representation.\nOur experiments show on-target adaptation achieves state-of-the-art accuracy and computational efficiency on common domain adaptation benchmarks.

        "question": "How do you reverse sear a steak on the Big Green Egg?",
        "evidence": "",
        "answer": "How to reverse Sear? The reverse sear is one of the most popular ways to grill a steak on the Big Green Egg, and my personal favorite. The key to the Reverse Sear is to start low and slow. It is much easier to raise the temp on the BGE than lower the temp. Ideally, the dome temp for a reverse sear is 250. However, I've had good success with the temp as low as 225 and as high as 300. \n\nFill your BGE up with your favorite lump charcoal up to the fire ring , light the fire and let it burn for about 9 minutes. Stir the coals so that the lit coals mix with unlit coals for an even cook.I prefer to cook my steak without adding wood chips as I don't want to overpower the meat...but if I were going to add chips I prefer post oak. Put the plate setter in with the legs up. Close the top and open the bottom vent and top vent with the opening about the size of a quarter. With the plate setter in, give it about 30 minutes to heat up the plate setter and stabilize at 250.\n\nNow that the Egg is stabilized at 250, time to add your steaks. You can pretty much reverse sear almost any cut but I prefer a ribeye, strip, or filet. The quintessential reverse sear cut is the bone-in ribeye, aka the cowboy or Tomahawk. The reverse sear works best with thick cuts. I would say the minimum thickness for a reverse sear is about 1 and a half inch, but the thicker the better. I look for the thickest cut possible for best results. I personally prefer to season my steaks with salt and pepper. My theory is that if you just spent $50 on a prime steak, then no need to overpower the meat with fancy seasoning. I want like the steaks to speak for themselves. The key to this stage is a good leave in thermometer. You want to roast the steaks until internal temp hits 113 degrees.  No more no less. When the internal temp hits 113, remove your steak to a cutting board and tent with foil.\n\t\nAt this point you should have pulled the steak with an internal temp of 113, and it should be resting on a tented cutting board. Final step of the reverse sear is the sear. Open up the top and remove the plate setter and grates.Open the bottom vent all the way and let the oxygen in to stoke the fire. I will give the coals another stir and about 5 minutes with the top open to gas up the fire. I then replace the grate, close the top and open all vents. The dome temp should climb rapidly. For a good sear you want it at least 450, with the ideal dome temp about 500-550. At this point you need to make a choice. You can either sear directly over the coals, or you can use a cast iron skillet with a butter bath. if you are going directly over the coals, its pretty simple. Place the steaks on the grate, and sear for about 90 seconds per side. If you use a cast iron skillet, I use a 50/50 mix of salted butter and olive oil. Butter has a lower scorch point, so if your skillet gets too hot you will burn the butter. I've also had good success with Avocado or Peanut oil that has a much higher scorch point. Add some garlic and thyme, sear for 90 seconds a side and don't forget to spoon the butter over the steaks for a little extra love. Remove the steaks and let them rest for 10 minutes. This is a critical step that will ensure the juices will stay in the meat.\n\nSlice and serve.",

This is followed by developing your knights. \n- The Fianchetto defense. You move your kingside knight's pawn forward 1 space, then you develop the kingside knight. You then put your kingside bishop in the square that the pawn used to be in, followed by castling. This opening is common among lower ranked players.\n- Four Knights Game: This doesn’t happen too much.

        "evidence": "",
        "answer": "The heart of a push rod internal combustion engine (ICE) is the crankshaft. Rods connect the engines pistons to the journals of the crankshaft. The crankshaft is evenly balanced by  weights on the opposite side of each journal to ensure that at high revolutions per minute (RPM) the motor is stable. As the crankshaft rotates it pushes the rods up and down that are connected to pistons. At the front of the crankshaft is a gear, the gear is typically connected via a chain to the camshaft. If the crankshaft is the heart of the engine, a camshaft is the brain of the engine. The camshaft determines when to open and close valves that let in air and fuel into each cylinder and let out exhaust from the internal combustion. The camshaft is a shaft that runs the length of the engine and has lobes on it, small metal cylinders called lifters ride on these lobes and are connected to push rods, the push rods are connected to rockers which rock back and forth opening and closing valves in the cylinder heads. The valves are located in the cylinder heads that sit on top of the cylinders that the pistons are in. As the pistons rotate up, a valve (being driven by the camshaft) opens to bring fuel into the cylinder, when the valve closes a spark from a spark plug, ignites the fuel causing a mini explosion pushing the cylinder down, a second valve opens letting the exhaust from the mini explosion exit the engine. This in turn rotates the crankshaft, pushing another piston up where the process continues. An intake manifold is like the lungs of a motor, it breaths in air from the atmosphere and mixes it with just the right amount of fuel to create that mini explosion in the cylinder.  The timing of the air, fuel, spark delivery is critical if it is off just the smallest of margins the engine will not run at all.",

        "evidence": "Seattle came in at No. 39 in the 2023 World's Best Cities Report, a comprehensive annual study by Resonance Consultancy. Seattle is a seaport city on the West Coast of the United States. The culture of Seattle is heavily defined by its significant musical history. Between 1918 and 1951, nearly 24 jazz nightclubs existed along Jackson Street, from the current Chinatown/International District to the Central District. The jazz scene nurtured the early careers of Ernestine Anderson, Ray Charles, Quincy Jones, and others. The city is also the origin of rock acts such as Foo Fighters, Heart, and Jimi Hendrix, as well as the grunge subgenre of rock and its pioneering bands Alice in Chains, Pearl Jam, Nirvana, and Soundgarden. The city itself is hilly, though not uniformly so. Like Rome, the city is said to lie on seven hills; the lists vary but typically include Capitol Hill, First Hill, West Seattle, Beacon Hill, Queen Anne, Magnolia, and the former Denny Hill. Due to its location in the Pacific Ring of Fire, Seattle is in a major earthquake zone. Temperature extremes are moderated by the adjacent Puget Sound, greater Pacific Ocean, and Lake Washington. Thus extreme heat waves are rare in the Seattle area, as are very cold temperatures (below about 15 °F (−9 °C)). The Seattle area is the cloudiest region of the United States, due in part to frequent storms and lows moving in from the adjacent Pacific Ocean. With many more \"rain days\" than other major American cities, Seattle has a well-earned reputation for frequent rain. Seattle's economy is driven by a mix of older industrial companies and \"new economy\" internet and technology companies, as well as service, design, and clean technology companies.",

        "question": "What is a symmetric label of IsNext of NSP?",
        "answer": "The authors propose a novel method, i.e., introducing a symmetric label of IsNext to the classification task, which is a symmetric label of IsNext of NSP.",
        "evidence": "The ability of semantic reasoning is essential for advanced natural language understanding (NLU) systems. Many NLU tasks that take sentence pairs as input, such as natural language inference (NLI) and machine reading comprehension (MRC), heavily rely on the ability of sophisticated semantic reasoning. For instance, the NLI task aims to determine whether the hypothesis sentence (e.g., a woman is sleeping) can be inferred from the premise sentence (e.g., a woman is talking on the phone). This requires the model to read and understand sentence pairs to make the specific semantic inference.\nBidirectional Encoder Representations from Transformer (BERT) BIBREF1 has shown strong ability in semantic reasoning. It was recently proposed and obtained impressive results on many tasks, ranging from text classification, natural language inference, and machine reading comprehension. BERT achieves this by employing two objectives in the pre-training, i.e., the masked language modeling (Masked LM) and the next sentence prediction (NSP). Intuitively, the Masked LM task concerns word-level knowledge, and the NSP task captures the global document-level information. The goal of NSP is to identify whether an input sentence is next to another input sentence. From the ablation study BIBREF1, the NSP task is quite useful for the downstream NLI and MRC tasks (e.g., +3.5% absolute gain on the Question NLI (QNLI) BIBREF2 task).\nDespite its usefulness, we suggest that BERT has not made full use of the document-level knowledge. The sentences in the negative samples used in NSP are randomly drawn from other documents. Therefore, to discriminate against these sentences, BERT is prone to aggregating the shallow semantic, e.g., topic, neglecting context clues useful for detailed reasoning. In other words, the canonical NSP task would encourage the model to recognize the correlation between sentences, rather than obtaining the ability of semantic entailment. This setting weakens the BERT model from learning specific semantic for inference. Another issue that renders NSP less effective is that BERT is order-sensitive. Performance degradation was observed on typical NLI tasks when the order of two input sentences are reversed during the BERT fine-tuning phase. It is reasonable as the NSP task can be roughly analogy to the NLI task when the input comes as (premise, hypothesis), considering the causal order among sentences. However, this identity between NSP and NLI is compromised when the sentences are swapped.\nBased on these considerations, we propose a simple yet effective method, i.e., introducing a IsPrev category to the classification task, which is a symmetric label of IsNext of NSP. The input of samples with IsPrev is the reverse of those with IsNext label. The advantages of using this previous sentence prediction (PSP) are three folds. (1) Learning the contrast between NSP and PSP forces the model to extract more detailed semantic, thereby the model is more capable of discriminating the correlation and entailment. (2) NSP and PSP are symmetric. This symmetric regularization alleviates the influence of the order of the input pair. (3) Empirical results indicate that our method is beneficial for all the semantic reasoning tasks that take sentence pair as input.\nIn addition, to further incorporating the document-level knowledge, NSP and PSP are extended with non-successive sentences, where the label smoothing technique is adopted. The proposed method yields a considerable improvement in our experiments. We evaluate the ability of semantic reasoning on standard NLI and MRC benchmarks, including the challenging HANS dataset BIBREF0. Analytical work on the HANS dataset provides a more comprehensible perspective towards the proposed method. Furthermore, the results on the Chinese benchmarks are provided to demonstrate its generality.\nIn summary, this work makes the following contributions:\nThe supervision signal from the original NSP task is weak for semantic inference. Therefore, a novel method is proposed to remedy the asymmetric issue and enhance the reasoning ability.\nBoth empirical and analytical evaluations are provided on the NLI and MRC datasets, which verifies the effectiveness of using more document-level knowledge.\nBased on these considerations, we propose a simple yet effective method, i.e., introducing a IsPrev category to the classification task, which is a symmetric label of IsNext of NSP.",

The second-stage boot loader does not need drivers for its own operation, but may instead use generic storage access methods provided by system firmware such as the BIOS or Open Firmware, though typically with restricted hardware functionality and lower performance.\n\nMany boot loaders can be configured to give the user multiple booting choices. These choices can include different operating systems (for dual or multi-booting from different partitions or drives), different versions of the same operating system (in case a new version has unexpected problems), different operating system loading options (e.g., booting into a rescue or safe mode), and some standalone programs that can function without an operating system, such as memory testers (e.g., memtest86+), a basic shell (as in GNU GRUB), or even games (see List of PC Booter games).Some boot loaders can also load other boot loaders; for example, GRUB loads BOOTMGR instead of loading Windows directly. Usually, a default choice is preselected with a time delay during which a user can press a key to change the choice; after this delay, the default choice is automatically run so normal booting can occur without interaction.\n\nThe boot process can be considered complete when the computer is ready to interact with the user, or the operating system is capable of running system programs or application programs.\n\nMany embedded systems must boot immediately. For example, waiting a minute for a digital television or a GPS navigation device to start is generally unacceptable. Therefore, such devices have software systems in ROM or flash memory so the device can begin functioning immediately; little or no loading is necessary, because the loading can be precomputed and stored on the ROM when the device is made.\n\nLarge and complex systems may have boot procedures that proceed in multiple phases until finally the operating system and other programs are loaded and ready to execute. Because operating systems are designed as if they never start or stop, a boot loader might load the operating system, configure itself as a mere process within that system, and then irrevocably transfer control to the operating system.

        "answer": "The QASENT dataset has been widely used for benchmarking the answer selection task.",
        "evidence": "Question answering (QA) has been a blooming research field for the last decade. Selection-based QA implies a family of tasks that find answer contexts from large data given questions in natural language. Three tasks have been proposed for selection-based QA. Given a document, answer extraction BIBREF0 , BIBREF1 finds answer phrases whereas answer selection BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 and answer triggering BIBREF6 , BIBREF7 find answer sentences instead, although the presence of the answer context is not assumed within the provided document for answer triggering but it is for the other two tasks. Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension. Finally, morales-EtAl:2016:EMNLP2016 provided InfoboxQA for answer selection.\nThese corpora make it possible to evaluate the robustness of statistical question answering learning. Although all of these corpora target on selection-based QA, they are designed for different purposes such that it is important to understand the nature of these corpora so a better use of them can be made. In this paper, we make both intrinsic and extrinsic analyses of four latest corpora based on Wikipedia, WikiQA, SelQA, SQuAD, and InfoboxQA. We first give a thorough intrinsic analysis regarding contextual similarities, question types, and answer categories (Section SECREF2 ). We then map questions in all corpora to the current version of English Wikipedia and benchmark another selection-based QA task, answer retrieval (Section SECREF3 ). Finally, we present an extrinsic analysis through a set of experiments cross-testing these corpora using a convolutional neural network architecture (Section SECREF4 ).\nWang et al.

        "evidence": "\"The sauna in Finland is an old phenomenon and its roots are difficult to trace, but its earliest versions are believed to be from 7000 BC.[citation needed] Bath houses were recorded in Europe during the same time period, but Finnish bathing habits were poorly documented for most of history. One of the first written mentions of what is believed to be the sauna customs of the forefathers of the Finns was written by Nestor the Chronicler in 1112. He told of \"\"hot wooden saunas in which naked bathers beat themselves with branches and finally pour cold water over themselves\"\".\n\nDuring the Reformation in Scandinavia the popularity of saunas expanded to other countries because the European bath houses were being destroyed.\n\nOne reason the sauna culture has always flourished in Finland has been because of the versatility of the sauna. When people were moving, the first thing they did was to build a sauna. Finns have used the sauna to live in, eat, address matters of hygiene, and, most importantly, give birth in an almost sterile environment. Unlike many other, more densely populated places in Europe, the availability of wood needed to build and warm the sauna has never been an issue. Another reason for its popularity is that in such a cold climate, the sauna allows people warmth for at least a short period of time. However, it is just as popular in the summer as in the winter.\"",

        "question": "Who introduced the concept of the electric field and what is it?",
        "evidence": "The concept of the electric field was introduced by Michael Faraday. An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field. The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses, and like it, extends towards infinity and shows an inverse square relationship with distance. However, there is an important difference. Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion. Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero. Thus gravity is the dominant force at distance in the universe, despite being much weaker.\nAn electric field generally varies in space and its strength at any one point is defined as the force (per unit charge) that would be felt by a stationary, negligible charge if placed at that point. The conceptual charge, termed a 'test charge', must be vanishingly small to prevent its own electric field disturbing the main field and must also be stationary to prevent the effect of magnetic fields. As the electric field is defined in terms of force, and force is a vector, having both magnitude and direction, so it follows that an electric field is a vector field.\nThe study of electric fields created by stationary charges is called electrostatics. The field may be visualised by a set of imaginary lines whose direction at any point is the same as that of the field. This concept was introduced by Faraday, whose term 'lines of force' still sometimes sees use. The field lines are the paths that a point positive charge would seek to make as it was forced to move within the field; they are however an imaginary concept with no physical existence, and the field permeates all the intervening space between the lines. Field lines emanating from stationary charges have several key properties: first, that they originate at positive charges and terminate at negative charges; second, that they must enter any good conductor at right angles, and third, that they may never cross nor close in on themselves.",

        "evidence": "Recent years, great efforts have been made on extracting relational fact from unstructured raw texts to build large structural knowledge bases. A relational fact is often represented as a triplet which consists of two entities (subject and object) and semantic relation between them. Early works BIBREF0, BIBREF1, BIBREF2 mainly focused on the task of relation classification which assumes the entity pair are identified beforehand. This limits their practical application since they neglect the extraction of entities. To extract both entities and their relation, existing methods can be divided into two categories : the pipelined framework, which first uses sequence labeling models to extract entities, and then uses relation classification models to identify the relation between each entity pair; and the joint approach, which combines the entity model and the relation model through different strategies, such as constraints or parameters sharing.\n\nOur model is based on this framework and make three improvements: (1) BERT [1] is introduced as a feature extraction layer in place of BiLSTM.

        "answer": "AE-HCN outperforms by 17%, AE-HCN-CNN outperforms by 20% on average",
        "evidence": "The goal of this paper is to propose a novel OOD detection method that does not require OOD data by utilizing counterfeit OOD turns in the context of a dialog. Most prior approaches do not consider dialog context and make predictions for each utterance independently. We will show that this independent decision leads to suboptimal performance even when actual OOD utterances are given to optimize the model and that the use of dialog context helps reduce OOD detection errors. To consider dialog context, we need to connect the OOD detection task with the overall dialog task. Thus, for this work, we build upon Hybrid Code Networks (HCN) BIBREF4 since HCNs achieve state-of-the-art performance in a data-efficient way for task-oriented dialogs, and propose AE-HCNs which extend HCNs with an autoencoder (Figure FIGREF8 ). Furthermore, we release new dialog datasets which are three publicly available dialog corpora augmented with OOD turns in a controlled way (exemplified in Table TABREF2 ) to foster further research.\nThe result is shown in Table TABREF23 . Since there are multiple actions that are appropriate for a given dialog context, we use per-utterance Precision@K as performance metric. We also report f1-score for OOD detection to measure the balance between precision and recall. The performances of HCN on Test-OOD are about 15 points down on average from those on Test, showing the detrimental impact of OOD utterances to such models only trained on in-domain training data. AE-HCN(-CNN) outperforms HCN on Test-OOD by a large margin about 17(20) points on average while keeping the minimum performance trade-off compared to Test. Interestingly, AE-HCN-CNN has even better performance than HCN on Test, indicating that, with the CNN encoder, counterfeit OOD augmentation acts as an effective regularization. In contrast, AE-HCN-Indep failed to robustly detect OOD utterances, resulting in much lower numbers for both metrics on Test-OOD as well as hurting the performance on Test. This result indicates two crucial points: 1) the inherent difficulty of finding an appropriate threshold value without actually seeing OOD data; 2) the limitation of the models which do not consider context. For the first point, Figure FIGREF24 plots histograms of reconstruction scores for IND and OOD utterances of bAbI6 Test-OOD. If OOD utterances had been known a priori, the threshold should have been set to a much higher value than the maximum reconstruction score of IND training data (6.16 in this case).\nThus, for this work, we build upon Hybrid Code Networks (HCN) BIBREF4 since HCNs achieve state-of-the-art performance in a data-efficient way for task-oriented dialogs, and propose AE-HCNs which extend HCNs with an autoencoder (Figure FIGREF8 ). \nAE-HCN(-CNN) outperforms HCN on Test-OOD by a large margin about 17(20) points on average while keeping the minimum performance trade-off compared to Test.

        "evidence": "How humans process language has become increasingly relevant in natural language processing since physiological data during language understanding is more accessible and recorded with less effort. In this work, we focus on eye-tracking and electroencephalography (EEG) recordings to capture the reading process. On one hand, eye movement data provides millisecond-accurate records about where humans look when they are reading, and is highly correlated with the cognitive load associated with different stages of text processing. On the other hand, EEG records electrical brain activity across the scalp and is a direct measure of physiological processes, including language processing. The combination of both measurement methods enables us to study the language understanding process in a more natural setting, where participants read full sentences at a time, in their own speed. Eye-tracking then permits us to define exact word boundaries in the timeline of a subject reading a sentence, allowing the extraction of brain activity signals for each word.\nHuman cognitive language processing data is immensely useful for NLP: Not only can it be leveraged to improve NLP applications (e.g. barrett2016weakly for part-of-speech tagging or klerke2016improving for sentence compression), but also to evaluate state-of-the-art machine learning systems. For example, hollenstein2019cognival evaluate word embeddings, or schwartz2019inducing fine-tune language models with brain-relevant bias.\nAdditionally, the availability of labelled data plays a crucial role in all supervised machine learning applications. Physiological data can be used to understand and improve the labelling process (e.g. tokunaga2017eye), and, for instance, to build cost models for active learning scenarios BIBREF0. Is it possible to replace this expensive manual work with models trained on physiological activity data recorded from humans while reading? That is to say, can we find and extract relevant aspects of text understanding and annotation directly from the source, i.e. eye-tracking and brain activity signals during reading?\nMotivated by these questions and our previously released dataset, ZuCo 1.0 BIBREF1, we developed this new corpus, where we specifically aim to collect recordings during natural reading as well as during annotation.\nWe provide the first dataset of simultaneous eye movement and brain activity recordings to analyze and compare normal reading to task-specific reading during annotation.

It was announced as the successor to the PlayStation 4 in April 2019, was launched on November 12, 2020, in Australia, Japan, New Zealand, North America, and South Korea, and was released worldwide one week later. The PS5 is part of the ninth generation of video game consoles, along with Microsoft's Xbox Series X/S consoles, which were released in the same month.\n\nThe base model includes an optical disc drive compatible with Ultra HD Blu-ray discs. The Digital Edition lacks this drive, as a lower-cost model for buying games only through download. The two variants were launched simultaneously.\n\nThe PlayStation 5's main hardware features include a solid-state drive customized for high-speed data streaming to enable significant improvements in storage performance, an AMD GPU capable of 4K resolution display at up to 120 frames per second, hardware-accelerated ray tracing for realistic lighting and reflections, and the Tempest Engine for hardware-accelerated 3D audio effects. Other features include the DualSense controller with haptic feedback, backward compatibility with the majority of PlayStation 4 and PlayStation VR games, and the PlayStation VR2 headset.\n\nHistory\nDevelopment\n\nMark Cerny, the PlayStation 5's chief architect\nThe lead architect of the PlayStation console line, Mark Cerny, implemented a two-year feedback cycle after the launch of the PlayStation 4. This entailed regularly visiting Sony's first-party developers at two-year intervals to find out what concerns they had with shortcomings in Sony's current hardware and how such hardware could be improved in console refreshes or for the next generation. This feedback was fed into the priorities for the console development team. In the development of the PlayStation 5, a key issue was the length of loading times for games. Cerny said several developers, including Epic Games' Tim Sweeney, told him that standard I/O speed of hard disk drives was now a limiting factor in pushing game development. Slow data rates placed limits on the size of data being loaded into the game, the physical location of data on the storage medium, and the duplication of data across the medium in order to reduce load times. An important goal was to find ways to reduce loading time, particularly in games that stream or dynamically load new game areas as the player moves through the game world.\n\nJim Ryan, the CEO of Sony Interactive Entertainment, stated that Sony had researched the feasibility of a \"low priced, reduced spec\" version of the PlayStation 5, like what Microsoft had done with its Xbox Series X and its lower-power counterpart the Xbox Series S; and concluded that they believed such consoles do not fare well, becoming obsolete too fast.\n\nMarketing and release\nCerny first publicly described the new console in an interview with Wired magazine in April 2019. In early 2019, Sony's financial report for the quarter ending March 31, 2019, affirmed that new next-generation hardware was in development but would ship no earlier than April 2020. In a second Wired magazine interview in October 2019, Sony said it intended to ship its next-generation console worldwide by the end of 2020. The current hardware specifications were revealed in October 2019. At CES 2020, Sony unveiled the official logo for the platform, which follows the similar minimalist styling of the previous PlayStation consoles and brand. Full specifications were given in an online presentation by Cerny and published by Sony and Digital Foundry on March 18, 2020. Digital Foundry spoke with Cerny in detail and published a \"deep dive\" on April 2.\n\nA major game library showcase had been planned for June 4, 2020, but was postponed until June 11 due to the George Floyd protests. This presentation was also the premiere of the console's external hardware design.\n\n\nEvent lighting being set up at SIE headquarters on the evening of November 8, four days before the launch on November 12, 2020.\nSony planned to launch the PlayStation 5 by the 2020 end-of-year holiday period. The date and pricing was confirmed as part of a game showcase presentation on September 16, 2020; the release date in Australia, Japan, New Zealand, North America, and South Korea was confirmed for November 12, 2020, and for most of the rest of the world on November 19, 2020.\n\nPlayStation 5's release in India was delayed, leading to speculation that a trademark dispute was the reason; the name \"PS5\" was briefly trademarked by a different person; eventually the dispute was resolved and the system released there on February 2, 2021.

The system launched in China on May 15, 2021.\n\nThe console launched with two models: a base version with an Ultra HD Blu-ray compatible optical disc drive for retail game support alongside online distribution via the PlayStation Store, and a lower-cost variant lacking the disc drive and retaining digital download support.\n\nFollowing the September 16, 2020, presentation, Sony stated that pre-orders for the console were to open at various retailers on the following day. However, several retailers in the United States and the United Kingdom launched pre-orders that evening, causing a rush on pre-orders, including scalping as many stores' inventories were quickly sold out, and creating confusion. Sony apologized for the incident on September 19, 2020, and promised to increase more pre-order deliveries over the coming days and stock through the end of the year.\n\nWorldwide supply of the console has remained low due to a global chip shortage since 2020. Sony expects a short retail stock until 2023. In August 2022, Sony announced a price increase by up to 20% in most of its markets except the US, citing global economic, inflationary, and supply chain pressures.",

        "evidence": "Training Language Models (LMs) is a straightforward way to collect a set of rules by utilizing the fact that words do not appear in an arbitrary order; we in fact can gain useful information about a word by knowing the company it keeps BIBREF7 . A statistical language model estimates the probability of a sequence of words or an upcoming word. An N-gram is a contiguous sequence of N words: a unigram is a single word, a bigram is a two-word sequence, and a trigram is a three-word sequence. For example, in the tweet\ntears in Ramen #SingleLifeIn3Words\n“tears”, “in”, “Ramen” and “#SingleLifeIn3Words” are unigrams; “tears in”, “in Ramen” and “Ramen #SingleLifeIn3Words” are bigrams and “tears in Ramen” and “in Ramen #SingleLifeIn3Words” are trigrams.\nAn N-gram model can predict the next word from a sequence of N-1 previous words. A trigram Language Model (LM) predicts the conditional probability of the next word using the following approximation: DISPLAYFORM0 \nThe assumption that the probability of a word depends only on a small number of previous words is called a Markov assumption BIBREF8 . Given this assumption the probability of a sentence can be estimated as follows: DISPLAYFORM0 \nIn a study on how phrasing affects memorability, BIBREF9 take a language model approach to measure the distinctiveness of memorable movie quotes. They do this by evaluating a quote with respect to a “common language” model built from the newswire sections of the Brown corpus BIBREF10 . They find that movie quotes which are less like “common language” are more distinctive and therefore more memorable. The intuition behind our approach is that humor should in some way be memorable or distinct, and so tweets that diverge from a “common language” model would be expected to be funnier.\nIn order to evaluate how funny a tweet is, we train language models on two datasets: the tweet data and the news data. Tweets that are more probable according to the tweet data language model are ranked as being funnier. However, tweets that have a lower probability according to the news language model are considered the funnier since they are the least like the (unfunny) news corpus. We relied on both bigrams and trigrams when training our models.\nWe use KenLM BIBREF11 as our language modeling tool. Language models are estimated using modified Kneser-Ney smoothing without pruning. KenLM also implements a back-off technique so if an N-gram is not found, KenLM applies the lower order N-gram's probability along with its back-off weights.\nIn a study on how phrasing affects memorability, (Danescu-Niculescu-Mizil et al., 2012) take a language model approach to measure the distinctiveness of memorable movie quotes.They do this by evaluating a quote with respect to a “common language” model built from the newswire sections of the Brown corpus (Kucera and Francis, 1967).",

In spite of the existing challenges, much research has been conducted on user-generated data in the field of information extraction, sentiment analysis, event extraction, user profiling and many more.\nAccording to Census of India, there are 22 scheduled languages and more than 100 non scheduled languages in India. There are 462 million internet users in India and most people know more than one language.

Suppose that events $x_1$ are $x_2$ are in the discourse relation of Cause (i.e., $x_1$ causes $x_2$). If the seed lexicon suggests $x_2$ is positive, $x_1$ is also likely to be positive because it triggers the positive emotion.

Similarly, if $x_1$ and $x_2$ are in the discourse relation of Concession (i.e., $x_2$ in spite of $x_1$), the reverse of $x_2$'s polarity can be propagated to $x_1$. Even if $x_2$'s polarity is not known in advance, we can exploit the tendency of $x_1$ and $x_2$ to be of the same polarity (for Cause) or of the reverse polarity (for Concession) although the heuristic is not exempt from counterexamples.

Board of Education of Topeka, 347 U.S. 483 (1954), was a landmark decision by the U.S. Supreme Court, which ruled that U.S. state laws establishing racial segregation in public schools are unconstitutional, even if the segregated schools are otherwise equal in quality. The decision partially overruled the Court's 1896 decision Plessy v. Ferguson, which had held that racial segregation laws did not violate the U.S. Constitution as long as the facilities for each race were equal in quality, a doctrine that had come to be known as \"separate but equal\".[note 1] The Court's decision in Brown paved the way for integration and was a major victory of the civil rights movement, and a model for many future impact litigation cases.\n\nThe underlying case began in 1951 when the public school system in Topeka, Kansas, refused to enroll local black resident Oliver Brown's daughter at the elementary school closest to their home, instead requiring her to ride a bus to a segregated black school farther away. The Browns and twelve other local black families in similar situations filed a class-action lawsuit in U.S. federal court against the Topeka Board of Education, alleging that its segregation policy was unconstitutional. A special three-judge court of the U.S. District Court for the District of Kansas rendered a verdict against the Browns, relying on the precedent of Plessy v. Ferguson and its \"separate but equal\" doctrine. The Browns, represented by NAACP chief counsel Thurgood Marshall, then appealed the ruling directly to the Supreme Court.\n\nIn May 1954, the Supreme Court issued a unanimous 9–0 decision in favor of the Browns. The Court ruled that \"separate educational facilities are inherently unequal\", and therefore laws that impose them violate the Equal Protection Clause of the Fourteenth Amendment of the U.S. Constitution. However, the decision's 14 pages did not spell out any sort of method for ending racial segregation in schools, and the Court's second decision in Brown II (349 U.S. 294 (1955)) only ordered states to desegregate \"with all deliberate speed\".\n\nIn the Southern United States, especially the \"Deep South\", where racial segregation was deeply entrenched, the reaction to Brown among most white people was \"noisy and stubborn\". Many Southern governmental and political leaders embraced a plan known as \"Massive Resistance\", created by Virginia Senator Harry F. Byrd, in order to frustrate attempts to force them to de-segregate their school systems. Four years later, in the case of Cooper v. Aaron, the Court reaffirmed its ruling in Brown, and explicitly stated that state officials and legislators had no power to nullify its ruling.",

        "evidence": "We consider the dataset consisting of the entire collection of articles of the Wikipedia Medicine Portal, updated at the end of 2014. Wikipedia articles are written according to the Media Wiki markup language, a HTML-like language. Among the structural elements of one page, which differs from standard HTML pages, there are i) the internal links, i.e., links to other Wikipedia pages, different from links to external resources); ii) categories, which represent the Media Wiki categories a page belongs to: they are encoded in the part of text within the Media Wiki “categories\" tag in the page source, and iii) informative boxes, so called “infoboxes\", which summarize in a structured manner some peculiar pieces of information related the topic of the article. The category values for the articles in the medical portal span over the ones listed at https://en.wikipedia.org/wiki/Portal:Medicine. Examples of categories, which appear at the bottom of each Wikipedia page, are in Fig. 1 .\nInfoboxes of the medical portal feature medical content and standard coding. As an example, Fig. 2 shows the infobox in the Alzheimer's disease page of the portal. The infobox contains explanatory figures and text denoting peculiar characteristics of the disease and the value for the standard code of such disease (ICD9, as for the international classification of the disease).\nThanks to WikiProject Medicine, the dataset of articles we collected from the Wikipedia Medicine Portal has been manually labeled into seven quality classes. They are ordered as Stub, Start, C, B, A, Good Article (GA), Featured Article (FA). The Featured and Good article classes are the highest ones: to have those labels, an article requires a community consensus and an official review by selected editors, while the other labels can be achieved with reviews from a larger, even controlled, set of editors. Actually, none of the articles in the dataset is labeled as A, thus, in the following, we do not consider that class, restricting the investigation to six classes.\nAt the date of our study, we were able to gather 24,362 rated documents. Remarkably, only a small percentage of them (1%) is labeled as GA and FA. Indeed, the distribution of the articles among the classes is highly skewed. There are very few (201) articles for the highest quality classes (FA and GA), while the vast majority (19,108) belongs to the lowest quality ones (Stub and Start). This holds not only for the medical portal. Indeed, it is common in all Wikipedia, where, on average, only one article in every thousand is a Featured one.\nIn Section \"Experiments and results\" , we will adopt a set of machine-learning classifiers to automatically label the articles into the quality classes. Dealing with imbalanced classes is a common situation in many real applications of classification learning: healthy patients over the population, fraudulent actions over daily genuine transactions, and so on. Without any countermeasure, common classifiers tend to correctly identify only articles belonging to the majority classes, clearly leading to severe mis-classification of the minority classes, since typical learning algorithms strive to maximize the overall prediction accuracy. To reduce the disequilibrium among the size of the classes, we have first randomly sampled the articles belonging to the most populated classes. Then, we have performed some further elaboration, as shown in the following.\nMany studies have been conducted to improve learning algorithms accuracy in presence of imbalanced data BIBREF8 . For the current work, we have considered one of the most popular approaches, namely the Synthetic Sampling with Data Generation, detailed in BIBREF9 . It consists in generating synthetic instances from the minority classes, to balance the overall dataset. The approach has been broadly applied to problems relying on NLP features, see, e.g., BIBREF10 . In our case, we resampled the input data set by applying the Synthetic Minority Oversampling TEchnique (SMOTE), with percentage 40% for GA and 180%, for FA. In particular, the steps to oversample are the following:\nTable 1 shows the number of articles in the dataset, divided per class, as well as the random samples we have considered for our study. The experiments presented in Section \"Experiments and results\" are based on the articles of the right-hand column in the table.\nAt the date of our study, we were able to gather 24,362 rated documents.",

        "question": "What is ICE’s advantage over the baseline methods when using a single model and dataset (i.e. the first set of rows in Table 2)?",
        "answer": "Table 2 shows that when given a single source model and dataset, ICE also outperforms the baselines. The possible reason is that ICE is trained to disturb source images without knowing label, which forces ICE to learn more generalizable perturbation pattern, and this ensures the advantage of ICE no matter the number of source models and datasets.",
        "evidence": "In this subsection, we perform GTA experiments on Cifar-100, which means we try to perturb Cifar-100 images to fool the target victim models. The models MobileNet-V3, VGG-16, ResNet-18, ResNet-34, SeResNet-26, and DenseNet-26 trained on Cifar-100 are used as victims to calculate the GTA success rate. All experimental results are reported in Table.\nIn the first experiment (the first row of Table), we use ResNet-18 and Cifar-10 as the source model and the source dataset, respectively, and conduct GTA on the testing images from Cifar-100. It is observed that among all baselines, FGSM performs the best. A possible underlying reason is that adversarial perturbations generated by multi-step gradient ascent tends to overfit the source model and source dataset. It can also be seen that the proposed ICE outperforms existing methods on the GTA problem. For instance, compared with FGSM, the average attack success rate on the six target models is improved by about 11.5%.\nIn the second experiment (the second row of Table), we consider the case where there are two source models -ResNet-18 and MobileNet-V1 trained on Cifar-10. Experimental results indicate that most of the baselines cannot leverage the additional source model MobileNet-V1 to boost their performances. In contrast, the proposed ICE can efficiently make use of the additional source model to improve its performances. For instance, by adding the MobileNet-V1 source model, the average attack success rate across 6 models of FGSM is decreased by about 0.7% while the success rate of ICE is improved by about 11.6%. In the third experiment, we use two ResNet-18 models trained on Cifar-10 and Tiered T 84 respectively as the source models, and use Cifar-10 and Tiered T 84 as the source datasets. It is interesting that the baselines' performances in this experiment are commonly worse than their performances in the first experiment. The possible reason for this result is that the resolution of the images from Tiered T 84 is 84×84, which differs greatly from the resolution of Cifar-100. As a comparison, ICE's performances in this experiment are much better than its performances in the first experiment, which indicates that ICE can efficiently make use of all the resources to improve the performance in spite of the difference among the source datasets.\nIn the fourth experiment, we use two ResNet-18 models respectively trained on Cifar-10 and Tiered T 56 as the source models. It is observed that most of the baselines' performances in this experiment are slightly better than their performances in the third experiment. For instance, compared with the performances in the third experiment, the performance of FGSM in this experiment is improved by about 1.7%. The possible reason for this result is that compared with the resolution of Tiered T 84 , the resolution of Tiered V 56 is more closer to the resolution of Cifar-100. In this experiment, the proposed ICE still outperforms all baselines with clear margins.\nIn the fifth experiment, we use three ResNet-18 models respectively trained on Cifar-10, Tiered T 84 and Tiered V 56 as the source models. It is clear that ICE's performances can be further improved by using more source datasets, while the baselines cannot efficiently utilize the additional source models to achieve better performances. AEG performs the best among all baselines with the average attack success rate of 58.3%. Compared with AEG, ICE promotes the average attack success rate by about 39.9%, which is a bigger margin than the margin in the first experiment. This experiment further indicates that ICE is more effective than baselines to leverage all the resource to solve the GTA problem.\n4.4 GENERALIZED TRANSFERABLE ATTACK TO CIFAR-10, TIERED T 84 , AND TIERED V 56\nWe have performed GTA on Cifar-100 in the previous subsection. Now we show ICE still outperforms baselines when using other datasets as target images. Table reports the experimental results. There are four datasets in total (Cifar-10, Cifar-100, Tiered T 84 , and Tiered V 56 ), and each row (denoted as -target) shows the experiment when conducting GTA on the target dataset by using ResNet-18 trained on the other three datasets as source models. For example, the '-Cifar10' row denotes the experiment that utilizing the datasets Cifar-100, Tiered T 84 , and Tiered V 56 and the three respectively trained ResNet-18 models to conduct GTA to the images from Cifar-10. Table does not show the '-Cifar100' row because the corresponding results have been shown in the last row of Table. It is clear that given three datasets and the models trained on the three datasets, ICE performs the best to attack unknown images from other datasets.\nTable 2: GTA success rates on Cifar-100",

        "evidence": "Despite its theoretical importance, critics of MPT question whether it is an ideal investment tool, because its model of financial markets does not match the real world in many ways\n\nThe risk, return, and correlation measures used by MPT are based on [expected values](https://en.wikipedia.org/wiki/Expected_value), which means that they are statistical statements about the future (the expected value of returns is explicit in the above equations, and implicit in the definitions of (https://en.wikipedia.org/wiki/Variance)\n and (https://en.wikipedia.org/wiki/Covariance)). Such measures often cannot capture the true statistical features of the risk and return which often follow highly skewed distributions (e.g. the [log-normal distribution](https://en.wikipedia.org/wiki/Log-normal_distribution)) and can give rise to, besides reduced (https://en.wikipedia.org/wiki/Volatility_(finance)), also inflated growth of return. In practice, investors must substitute predictions based on historical measurements of asset return and volatility for these values in the equations. Very often such expected values fail to take account of new circumstances that did not exist when the historical data were generated.\n\nMore fundamentally, investors are stuck with estimating key parameters from past market data because MPT attempts to model risk in terms of the likelihood of losses, but says nothing about why those losses might occur. The risk measurements used are (https://en.wikipedia.org/wiki/Probability) in nature, not structural. This is a major difference as compared to many engineering approaches to [risk management](https://en.wikipedia.org/wiki/Risk_management).\n\nMathematical risk measurements are also useful only to the degree that they reflect investors' true concerns—there is no point minimizing a variable that nobody cares about in practice. In particular, (https://en.wikipedia.org/wiki/Variance) is a symmetric measure that counts abnormally high returns as just as risky as abnormally low returns. The psychological phenomenon of [loss aversion](https://en.wikipedia.org/wiki/Loss_aversion) is the idea that investors are more concerned about losses than gains, meaning that our intuitive concept of risk is fundamentally asymmetric in nature. There many other risk measures (like [coherent risk measures](https://en.wikipedia.org/wiki/Coherent_risk_measure)) might better reflect investors' true preferences.\n\nModern portfolio theory has also been criticized because it assumes that returns follow a [Gaussian distribution](https://en.wikipedia.org/wiki/Normal_distribution). Already in the 1960s, [Benoit Mandelbrot](https://en.wikipedia.org/wiki/Benoit_Mandelbrot) and [Eugene Fama](https://en.wikipedia.org/wiki/Eugene_Fama) showed the inadequacy of this assumption and proposed the use of more general [stable distributions](https://en.wikipedia.org/wiki/Stable_distributions) instead. [Stefan Mittnik](https://en.wikipedia.org/wiki/Stefan_Mittnik) and [Svetlozar Rachev](https://en.wikipedia.org/wiki/Svetlozar_Rachev) presented strategies for deriving optimal portfolios in such settings.\n\n[Contrarian investors](https://en.wikipedia.org/wiki/Contrarian_investing) and [value investors](https://en.wikipedia.org/wiki/Value_investing) typically do not subscribe to Modern Portfolio Theory. One objection is that the MPT relies on the [efficient-market hypothesis](https://en.wikipedia.org/wiki/Efficient-market_hypothesis)\n and uses fluctuations in share price as a substitute for risk. [Sir John Templeton](https://en.wikipedia.org/wiki/Sir_John_Templeton)\n believed in diversification as a concept, but also felt the theoretical foundations of MPT were questionable, and concluded (as described by a biographer): \"the notion that building portfolios on the basis of unreliable and irrelevant statistical inputs, such as historical volatility, was doomed to failure.",

However, this metric doesn’t reflect investors’ true concerns in practice. Variance is symmetric, so it punishes high returns the same way as high losses. However, investors care more about loss than gain, so the perception of risk is asymmetric in nature. Coherent risk measures should be a better metric that reflects investors’ preference\n- MPT assumes that returns follow Gaussian distribution.

Sir Francis Galton took another approach to assessing personality late in the 19th century. Based on the lexical hypothesis, Galton estimated the number of adjectives that described personality in the English dictionary. Galton's list was eventually refined by Louis Leon Thurstone to 60 words that were commonly used for describing personality at the time. Through factor analyzing responses from 1300 participants, Thurstone was able to reduce this severely restricted pool of 60 adjectives into seven common factors. This procedure of factor analyzing common adjectives was later utilized by Raymond Cattell (7th most highly cited psychologist of the 20th Century—based on the peer-reviewed journal literature), who subsequently utilized a data set of over 4000 affect terms from the English dictionary that eventually resulted in construction of the Sixteen Personality Factor Questionnaire (16PF) which also measured up to eight second-stratum personality factors. Of the many introspective (i.e., subjective) self-report instruments constructed to measure the putative Big Five personality dimensions, perhaps the most popular has been the Revised NEO Personality Inventory (NEO-PI-R) However, the psychometric properties of the NEO-PI-R (including its factor analytic/construct validity) has been severely criticized.",

        "evidence": "Events are a kind of important objective information of the world. Structuralizing and representing such information as machine-readable knowledge are crucial to artificial intelligence BIBREF0, BIBREF1. The main idea is to learn distributed representations for structured events (i.e. event embeddings) from text, and use them as the basis to induce textual features for downstream applications, such as script event prediction and stock market prediction.\nParameterized additive models are among the most widely used for learning distributed event representations in prior work BIBREF2, BIBREF3, which passes the concatenation or addition of event arguments' word embeddings to a parameterized function. The function maps the summed vectors into an event embedding space. Furthermore, BIBREF4 ding2015deep and BIBREF5 weber2018event propose using neural tensor networks to perform semantic composition of event arguments, which can better capture the interactions between event arguments.\nThis line of work only captures shallow event semantics, which is not capable of distinguishing events with subtle differences. On the one hand, the obtained event embeddings cannot capture the relationship between events that are syntactically or semantically similar, if they do not share similar word vectors. For example, as shown in Figure FIGREF2 (a), “PersonX threw bomb” and “PersonZ attacked embassy”. On the other hand, two events with similar word embeddings may have similar embeddings despite that they are quite unrelated, for example, as shown in Figure FIGREF2 (b), “PersonX broke record” and “PersonY broke vase”. Note that in this paper, similar events generally refer to events with strong semantic relationships rather than just the same events.\nOne important reason for the problem is the lack of the external commonsense knowledge about the mental state of event participants when learning the objective event representations. In Figure FIGREF2 (a), two event participants “PersonY” and “PersonZ” may carry out a terrorist attack, and hence, they have the same intent: “to bloodshed”, which can help representation learning model maps two events into the neighbor vector space. In Figure FIGREF2 (b), a change to a single argument leads to a large semantic shift in the event representations, as the change of an argument can result in different emotions of event participants. Who “broke the record” is likely to be happy, while, who “broke a vase” may be sad. Hence, intent and sentiment can be used to learn more fine-grained semantic features for event embeddings.\nSuch commonsense knowledge is not explicitly expressed but can be found in a knowledge base such as Event2Mind BIBREF6 and ATOMIC BIBREF7. Thus, we aim to incorporate the external commonsense knowledge, i.e., intent and sentiment, into the learning process to generate better event representations. Specifically, we propose a simple and effective model to jointly embed events, intents and emotions into the same vector space. A neural tensor network is used to learn baseline event embeddings, and we define a corresponding loss function to incorporate intent and sentiment information.\nExtensive experiments show that incorporating external commonsense knowledge brings promising improvements to event embeddings, achieving 78% and 200% improvements on hard similarity small and big dataset, respectively. With better embeddings, we can achieve superior performances on script event prediction and stock market prediction compared to state-of-the-art baseline methods.\nSpecifically, we propose a simple and effective model to jointly embed events, intents and emotions into the same vector space.",

Compared to phrase-based Statistical Machine Translation (SMT) which is basically an ensemble of different features trained and tuned separately, NMT directly modeling the translation relationship between source and target sentences. Unlike SMT, NMT does not require much linguistic information and large monolingual data to achieve good performances.\nAn NMT consists of an encoder which recursively reads and represents the whole source sentence into a context vector and a recurrent decoder which takes the context vector and its previous state to predict the next target word. It is then trained in an end-to-end fashion to learn parameters which maximizes the likelihood between the outputs and the references. Recently, attention-based NMT has been featured in most state-of-the-art systems. First introduced by BIBREF2 , attention mechanism is integrated in decoder side as feedforward layers. It allows the NMT to decide which source words should take part in the predicting process of the next target words. It helps to improve NMTs significantly. Nevertheless, since the attention mechanism is specific to a particular source sentence and the considering target word, it is also specific to particular language pairs.\nSome recent work has focused on extending the NMT framework to multilingual scenarios. By training such network using parallel corpora in number of different languages, NMT could benefit from additional information embedded in a common semantic space across languages. Basically, the proposed NMT are required to employ multiple encoders or multiple decoders to deal with multilinguality. Furthermore, in order to avoid the tight dependency of the attention mechanism to specific language pairs, they also need to modify their architecture to combine either the encoders or the attention layers. These modifications are specific to the purpose of the tasks as well. Thus, those multilingual NMTs are more complicated, much more free parameters to learn and more difficult to perform standard trainings compared to the original NMT.\nIn this paper, we introduce a unified approach to seamlessly extend the original NMT to multilingual settings. Our approach allows us to integrate any language in any side of the encoder-decoder architecture with only one encoder and one decoder for all the languages involved. Moreover, it is not necessary to do any network modification to enable attention mechanism in our NMT systems. We then apply our proprosed framework in two demanding scenarios: under-resourced translation and zero-resourced translation. The results show that bringing multilinguality to NMT helps to improve individual translations. With some insightful analyses of the results, we set our goal toward a fully multilingual NMT framework.\nThe paper starts with a detailed introduction to attention-based NMT. In Section SECREF3 , related work about multi-task NMT is reviewed. Section SECREF5 describes our proposed approach and thorough comparisons to the related work.

        "question": "what is Modern Talking?",
        "evidence": "Modern Talking was a German pop music duo consisting of arranger, songwriter and producer Dieter Bohlen and singer Thomas Anders. They have been referred to as Germany's most successful pop duo, and have had a number of hit singles, reaching the top five in many countries. Their most popular singles are \"You're My Heart, You're My Soul\", \"You Can Win If You Want\", \"Cheri, Cheri Lady\", \"Brother Louie\", \"Atlantis Is Calling (S.O.S. for Love)\" and \"Geronimo's Cadillac\".\nModern Talking worked together from 1983 to 1987, then the band disbanded. In 1998, they reunited and made a successful comeback, recording and releasing music from 1998 to 2003. The duo released singles (many of which involved American rapper Eric Singleton) which again entered the top ten in Germany and abroad, one of which was the re-recorded version of \"You're My Heart, You're My Soul '98\". After the duo's second and final break-up in 2003, their global sales had reached 120 million singles and albums combined.",
        "answer": "First formed in West Berlin in early 1983, they unexpectedly became popular in the beginning of 1985 with \"You're My Heart, You're My Soul\", with which they occupied top ten positions in 35 countries including their homeland where the single perched at the top for six consecutive weeks, the single eventually went on to sell eight million copies worldwide. The track was then followed by another number-one hit, \"You Can Win If You Want\", which was released in the middle of 1985 from the debut album The 1st Album. The album was certified platinum in Germany for selling over 500,000 units.\n\nSoon after their second hit, Modern Talking released the single \"Cheri, Cheri Lady\" which also quickly climbed to the top of the charts in West Germany, Switzerland, Austria and Norway, meanwhile entering the top ten in Sweden and the Netherlands. The single, being the only track released from their second album Let's Talk About Love, managed to push the album to a platinum status in West Germany for sales of over 500,000. The success continued with another two number one singles, \"Brother Louie\" and \"Atlantis Is Calling (S.O.S. for Love)\", both from the third album, Ready for Romance. The duo also charted high with their sixth single \"Geronimo's Cadillac\" from the fourth album In the Middle of Nowhere, and \"Jet Airliner\" from their fifth album Romantic Warriors.\n\nDue to their lackluster received sixth album, Bohlen announced the end of the project during an interview, while Anders was in Los Angeles. This sparked further animosities between the two, who had had a tumultuous and quarreling relationship even when they were together. According to Bohlen, the main reason for breaking up the group was Anders' then-wife Nora, who refused to have her husband interviewed by female reporters, and constantly demanded huge changes made to shows, videos or recordings, a fact that Anders later admitted in his biography. After a final phone call during which both men heavily insulted each other, they refused to speak with each other for over 10 years.\n\nDuring this era, Modern Talking were successful in Europe, Asia, South America, the Middle East and in Iran. In the United Kingdom, they entered the top five only once, with the song \"Brother Louie\". In 1985, RCA signed Modern Talking for a US deal and released their first album in the US, but they remained almost unknown in North America, never appearing on the US charts. They released two albums each year between 1985 and 1987, while also promoting their singles on television all over Europe, eventually selling sixty-five million records within three years.\n\nNotably, Modern Talking were one of the first Western bloc bands allowed to sell their records in the Soviet Union. After four decades of Cold War censorship and import restrictions, Mikhail Gorbachev's Glasnost reforms in 1986 opened the Soviet sphere to Western bands, including Modern Talking at the height of their popularity. As a result, they still maintain a large fanbase in Eastern Europe.\n\nBetween 1987 and 1997\nImmediately after the duo split in mid-1987, Bohlen formed his own project called Blue System and enjoyed several high chart positions, with tracks like \"Sorry Little Sarah\", \"My Bed Is Too Big\", \"Under My Skin\", \"Love Suite\", \"Laila\" and \"Déjà vu\". Meanwhile, Anders went solo, touring under the name of Modern Talking on several continents until the beginning of 1989, when he started to record some of his new pop-like material in LA and London, and also in his native country. Anders recorded five solo albums in English, Different, Whispers, Down on Sunset, When Will I See You Again and Souled, and one of his albums was also recorded in Spanish Barcos de Cristal. He was more successful in foreign countries than his own country, yet he also reached several hits in Germany. Despite all the quarrels and disagreements that Bohlen and Anders got into with each other in the past, they began staying in touch again after Anders moved back to Koblenz, Germany in 1994.\n\n1998–2003: Reunion\nIn the beginning of 1998, the duo reunited and had their first performance together in March on the German TV show Wetten, dass..?. They released a remixed version of their 1984 single \"You're My Heart, You're My Soul\", which features Eric Singleton on the rap vocals. Their first comeback album Back for Good, which included four new tracks, as well as all of the previous hits remixed with modern techniques, stayed at number one in Germany for five consecutive weeks and managed to top the charts in fifteen countries, eventually selling three million copies in Europe alone. The duo won the award for Best Selling German Band at the World Music Awards that year. The follow-up album Alone also went straight to number one in Germany and was very successful elsewhere; the album managed to sell over one million units in Europe alone.\n\nBohlen and Anders followed the 1980s Modern Talking pattern as they chose to release two singles from each album, as in the past. A series of singles and four more albums followed such as Year of the Dragon, America, Victory and Universe. After reaching the point where they had already collected over 400 gold and platinum awards worldwide, Bohlen and Anders decided to disband again in 2003 just before the release of another best-of compilation. The second break-up seemed to have been triggered mainly from the negative portrayal of Anders by Bohlen written in his autobiography published on 4 October 2003. In the course of all the disputes which eventually drove the duo to its break-up, Bohlen was involved in Deutschland sucht den Superstar (DSDS), the German edition of the UK's Pop Idol. The compilation album was released in 2003 entitled The Final Album which contained all of the duo's singles. Thomas Anders started another solo career immediately after the end of Modern Talking, while Bohlen had by now begun devoting most of his time to new talents, especially those he discovered on DSDS.",

        "question": "What is pleitropy?",
        "evidence": "",
        "answer": "Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits. Such a gene that exhibits multiple phenotypic expression is called a pleiotropic gene. Mutation in a pleiotropic gene may have an effect on several traits simultaneously, due to the gene coding for a product used by a myriad of cells or different targets that have the same signaling function.\n\nPleiotropy can arise from several distinct but potentially overlapping mechanisms, such as gene pleiotropy, developmental pleiotropy, and selectional pleiotropy. Gene pleiotropy occurs when a gene product interacts with multiple other proteins or catalyzes multiple reactions. Developmental pleiotropy occurs when mutations have multiple effects on the resulting phenotype. Selectional pleiotropy occurs when the resulting phenotype has many effects on fitness (depending on factors such as age and gender).\n\nAn example of pleiotropy is phenylketonuria, an inherited disorder that affects the level of phenylalanine, an amino acid that can be obtained from food, in the human body. Phenylketonuria causes this amino acid to increase in amount in the body, which can be very dangerous. The disease is caused by a defect in a single gene on chromosome 12 that codes for enzyme phenylalanine hydroxylase, that affects multiple systems, such as the nervous and integumentary system.\n\nPleiotropic gene action can limit the rate of multivariate evolution when natural selection, sexual selection or artificial selection on one trait favors one allele, while selection on other traits favors a different allele. Some gene evolution is harmful to an organism. Genetic correlations and responses to selection most often exemplify pleiotropy.",

        "answer": "The opinions on this question vary from person to person. \nStatistically, a pattern of preference is easily visible on what people would describe as beautiful. An evident example of this phenomenon is a beauty standard for women and men. Society seems to agree on what features, both physical and internal, can deem a person beautiful. The standard of beauty is also projected beyond humans, onto animal breeds, for example, in cat shows. \nA link between beauty and how closely it resembles perfection appears to exist. For example, a rose with many petals and no tears or scratches is generally seen as more beautiful than one with fewer, visibly ruined petals. \nHowever, the question of perfection also raises a problem as it is difficult and arguably impossible to define perfection. Beauty does not necessarily mean perfection. For example, large eyes are statistically considered to be more attractive however, in terms of their biological  purpose they possess no superiority to small eyes. Therefore, both beauty and perfection depend on the perspective or purpose with which you observe an object.\n\nFurthermore, the clear fluctuations through centuries and cultures on what is considered to be beautiful should also be taken into account. Fashion trends and art styles, for instance,  are constantly changing. Additionally, the diversity in opinions suggests there is nothing that is considered beautiful by everyone, so even if the majority deem a particular object or thing as beautiful, it’s beauty remains subjective because it remains based on an ever-changing preference rather than objective truth.",

        "answer": "Yes, only a minor adjustment is needed.",
        "evidence": "Automatic Text Summarization deals with the task of condensing documents into a summary, whose level is similar to a human-generated summary. It is mostly distributed into two distinct domains, i.e., Abstractive Summarization and Extractive Summarization. Abstractive summarization( Dejong et al. ,1978) involves models to deduce the crux of the document. It then presents a summary consisting of words and phrases that were not there in the actual document, sometimes even paraphrasing BIBREF1 . A state of art method proposed by Wenyuan Zeng BIBREF2 produces such summaries with length restricted to 75. There have been many recent developments that produce optimal results, but it is still in a developing phase. It highly relies on natural language processing techniques, which is still evolving to match human standards. These shortcomings make abstractive summarization highly domain selective. As a result, their application is skewed to the areas where NLP techniques have been superlative. Extractive Summarization, on the other hand, uses different methods to identify the most informative/dominant sentences through the text, and then present the results, ranking them accordingly. In this paper, we have proposed two novel stand-alone summarization methods.The first method is based on Glove Model BIBREF3 ,and other is based on Facebook's InferSent BIBREF4 . We have also discussed how we can effectively subdue shortcomings of one model by using it in coalition with models which capture the view that other faintly held.\nAdditional experiments on a large Natural Language Inference (NLI) task illustrate that our method can be easily applied to more NLP tasks with only a minor adjustment.",

        "evidence": "We propose a monolingual DocRepair model to correct inconsistencies between sentence-level translations of a context-agnostic MT system. It does not use any states of a trained MT model whose outputs it corrects and therefore can in principle be trained to correct translations from any black-box MT system.\nThe DocRepair model requires only monolingual document-level data in the target language. It is a monolingual sequence-to-sequence model that maps inconsistent groups of sentences into consistent ones. Consistent groups come from monolingual document-level data. To obtain inconsistent groups, each sentence in a group is replaced with its round-trip translation produced in isolation from context. More formally, forming a training minibatch for the DocRepair model involves the following steps (see also Figure FIGREF9):\nsample several groups of sentences from the monolingual data;\nfor each sentence in a group, (i) translate it using a target-to-source MT model, (ii) sample a translation of this back-translated sentence in the source language using a source-to-target MT model;\nusing these round-trip translations of isolated sentences, form an inconsistent version of the initial groups;\nuse inconsistent groups as input for the DocRepair model, consistent ones as output.\nAt test time, the process of getting document-level translations is two-step (Figure FIGREF10):\nproduce translations of isolated sentences using a context-agnostic MT model;\napply the DocRepair model to a sequence of context-agnostic translations to correct inconsistencies between translations.\nIn the scope of the current work, the DocRepair model is the standard sequence-to-sequence Transformer. Sentences in a group are concatenated using a reserved token-separator between sentences. The Transformer is trained to correct these long inconsistent pseudo-sentences into consistent ones. The token-separator is then removed from corrected translations.\nWe propose a monolingual DocRepair model to correct inconsistencies between sentence-level translations of a context-agnostic MT system.",

        "evidence": "Keyphrases are single or multi-word lexical units that best summarise a document BIBREF0. As such, they are of great importance for indexing, categorising and browsing digital libraries BIBREF1. Yet, very few documents have keyphrases assigned, thus raising the need for automatic keyphrase generation systems. This task falls under the task of automatic keyphrase extraction which can also be the subtask of finding keyphrases that only appear in the input document. Generating keyphrases can be seen as a particular instantiation of text summarization, where the goal is not to produce a well-formed piece of text, but a coherent set of phrases that convey the most salient information. Those phrases may or may not appear in the document, the latter requiring some form of abstraction to be generated. State-of-the-art systems for this task rely on recurrent neural networks BIBREF2, BIBREF3, BIBREF4, and hence require large amounts of annotated training data to achieve good performance. As gold annotated data is expensive and difficult to obtain BIBREF5, previous works focused on readily available scientific abstracts and used author-assigned keyphrases as a proxy for expert annotations. However, this poses two major issues: 1) neural models for keyphrase generation do not generalize well across domains, thus limiting their use in practice; 2) author-assigned keyphrases exhibit strong consistency issues that negatively impacts the model's performance. There is therefore a great need for annotated data from different sources, that is both sufficiently large to support the training of neural-based models and that comprises gold-standard labels provided by experts. In this study, we address this need by providing KPTimes, a dataset made of 279 923 news articles that comes with editor-assigned keyphrases.\nOnline news are particularly relevant to keyphrase generation since they are a natural fit for faceted navigation BIBREF6 or topic detection and tracking BIBREF7. Also, and not less importantly, they are available in large quantities and are sometimes accompanied by metadata containing human-assigned keyphrases initially intended for search engines. Here, we divert these annotations from their primary purpose, and use them as gold-standard labels to automatically build our dataset. More precisely, we collect data by crawling selected news websites and use heuristics to draw texts paired with gold keyphrases. We then explore the resulting dataset to better understand how editors tag documents, and how these expert annotations differ from author-assigned keyphrases found in scholarly documents. Finally, we analyse the performance of state-of-the-art keyphrase generation models and investigate their transferability to the news domain and the impact of domain shift.\nMore precisely, we collect data by crawling selected news websites and use heuristics to draw texts paired with gold keyphrases.",

A Gini coefficient of 0 reflects perfect equality, where all income or wealth values are the same, while a Gini coefficient of 1 (or 100%) reflects maximal inequality among values. For example, if everyone has the same income, the Gini coefficient will be 0. In contrast, a Gini coefficient of 1 indicates that within a group of people, a single individual has all the income or consumption, while all others have none.\nThe Gini coefficient was proposed by Corrado Gini as a measure of inequality of income or wealth.  For OECD countries, in the late 20th century, considering the effect of taxes and transfer payments, the income Gini coefficient ranged between 0.24 and 0.49, with Slovenia being the lowest and Mexico the highest.

        "question": "What corpus did the authors define for each language?",
        "answer": "The authors define a train, development and test corpus for each language.",
        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nFor each language, we define a train, development and test corpus.",

First, it's important to remain patient and diligent around maintaining a strict schedule for feeding, rest, play and potty times.  This should start the  moment your puppy arrives as this is going to set them and you up for success.  Second, when accidents happen, which will occur for the first few weeks, remember to be patient and kind to your puppy.  This will develop a deep sense of trust in you as the authority figure in the home.  \n\nGenerally, puppies need to be let outside to go potty outside within a secure area after waking, playtime and after every meal.  It's important not to confuse potty time with playtime and that your puppy is placed safely in a crate or gated area if they aren't being watched closely.   \n\nHow do you know when your puppy needs to go potty?  \n\nMost puppies will begin sniffing the ground when they need to go potty so if you witness this happening indoors, quickly usher your puppy outside or to a training pad.  It's important to provide your puppy a lot of praise for a job well done.  For some puppies, verbal praise from their family member while providing them with a small treat will help your puppy make the connection that going potty in the appropriate area is a very good thing for them and for you.",

It is commonly used to train and evaluate neural network models that generate image descriptions (e.g. BIBREF2 ). An untested assumption behind the dataset is that the descriptions are based on the images, and nothing else. Here are the authors (about the Flickr8K dataset, a subset of Flickr30K):\n“By asking people to describe the people, objects, scenes and activities that are shown in a picture without giving them any further information about the context in which the picture was taken, we were able to obtain conceptual descriptions that focus only on the information that can be obtained from the image alone.” BIBREF1 \nWhat this assumption overlooks is the amount of interpretation or recontextualization carried out by the annotators. Let us take a concrete example. Figure FIGREF1 shows an image from the Flickr30K dataset.\nThis image comes with the five descriptions below. All but the first one contain information that cannot come from the image alone. Relevant parts are highlighted in bold:\nWe need to understand that the descriptions in the Flickr30K dataset are subjective descriptions of events. This can be a good thing: the descriptions tell us what are the salient parts of each image to the average human annotator. So the two humans in Figure FIGREF1 are relevant, but the two soap dispensers are not. But subjectivity can also result in stereotypical descriptions, in this case suggesting that the male is more likely to be the manager, and the female is more likely to be the subordinate. rashtchian2010collecting do note that some descriptions are speculative in nature, which they say hurts the accuracy and the consistency of the descriptions. But the problem is not with the lack of consistency here. Quite the contrary: the problem is that stereotypes may be pervasive enough for the data to be consistently biased. And so language models trained on this data may propagate harmful stereotypes, such as the idea that women are less suited for leadership positions.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices. I will build on earlier work on linguistic bias in general BIBREF3 , providing examples from the Flickr30K data, and present a taxonomy of unwarranted inferences. Finally, I will discuss several methods to analyze the data in order to detect biases.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices.",

        "answer": "All the training examples in the series come from multiple datasets of the same task (e.g., a text classification task, a question answering task, etc.) and each dataset comes one after the other.",
        "evidence": "The ability to continuously learn and accumulate knowledge throughout a lifetime and reuse it effectively to adapt to a new problem quickly is a hallmark of general intelligence. State-of-the-art machine learning models work well on a single dataset given enough training examples, but they often fail to isolate and reuse previously acquired knowledge when the data distribution shifts (e.g., when presented with a new dataset)—a phenomenon known as catastrophic forgetting BIBREF0 , BIBREF1 .\nThe three main approaches to address catastrophic forgetting are based on: (i) augmenting the loss function that is being minimized during training with extra terms (e.g., a regularization term, an optimization constraint) to prevent model parameters learned on a new dataset from significantly deviating from parameters learned on previously seen datasets BIBREF2 , BIBREF3 , BIBREF4 , (ii) adding extra learning phases such as a knowledge distillation phase, an experience replay BIBREF5 , BIBREF6 , and (iii) augmenting the model with an episodic memory module BIBREF7 . Recent methods have shown that these approaches can be combined—e.g., by defining optimization constraints using samples from the episodic memory BIBREF8 , BIBREF9 .\nIn language learning, progress in unsupervised pretraining BIBREF10 , BIBREF11 , BIBREF12 has driven advances in many language understanding tasks BIBREF13 , BIBREF14 . However, these models have been shown to require a lot of in-domain training examples, rapidly overfit to particular datasets, and are prone to catastrophic forgetting BIBREF15 , making them unsuitable as a model of general linguistic intelligence.\nIn this paper, we investigate the role of episodic memory for learning a model of language in a lifelong setup. We propose to use such a component for sparse experience replay and local adaptation to allow the model to continually learn from examples drawn from different data distributions. In experience replay, we randomly select examples from memory to retrain on. Our model only performs experience replay very sparsely to consolidate newly acquired knowledge with existing knowledge in the memory into the model. We show that a 1% experience replay to learning new examples ratio is sufficient. Such a process bears some similarity to memory consolidation in human learning BIBREF16 . In local adaptation, we follow Memory-based Parameter Adaptation BIBREF7 and use examples retrieved from memory to update model parameters used to make a prediction of a particular test example.\nOur setup is different than a typical lifelong learning setup. We assume that the model only makes one pass over the training examples, similar to BIBREF9 . However, we also assume neither our training nor test examples have dataset identifying information (e.g., a dataset identity, a dataset descriptor). Our experiments focus on lifelong language learning on two tasks—text classification and question answering. BIBREF17 show that many language processing tasks (e.g., classification, summarization, natural language inference, etc.) can be formulated as a question answering problem. We argue that our lifelong language learning setup—where a model is presented with question-answer examples without an explicit identifier about which dataset (distribution) the examples come from—is a more realistic setup to learn a general linguistic intelligence model.\nOur main contributions in this paper are:\nWe assume that all our training examples in the series come from multiple datasets of the same task (e.g., a text classification task, a question answering task), and each dataset comes one after the other.",

        "evidence": " This work is licensed under a Creative Commons Attribution 4.0 International License. License details: http://creativecommons.org/licenses/by/4.0/\nEntity linking (EL), mapping entity mentions in texts to a given knowledge base (KB), serves as a fundamental role in many fields, such as question answering BIBREF0 , semantic search BIBREF1 , and information extraction BIBREF2 , BIBREF3 . However, this task is non-trivial because entity mentions are usually ambiguous. As shown in Figure FIGREF1 , the mention England refers to three entities in KB, and an entity linking system should be capable of identifying the correct entity as England cricket team rather than England and England national football team.\nEntity linking is typically broken down into two main phases: (i) candidate generation obtains a set of referent entities in KB for each mention, and (ii) named entity disambiguation selects the possible candidate entity by solving a ranking problem. The key challenge lies in the ranking model that computes the relevance between candidates and the corresponding mentions based on the information both in texts and KBs BIBREF4 . In terms of the features used for ranking, we classify existing EL models into two groups: local models to resolve mentions independently relying on textual context information from the surrounding words BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , and global (collective) models, which are the main focus of this paper, that encourage the target entities of all mentions in a document to be topically coherent BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 .\nGlobal models usually build an entity graph based on KBs to capture coherent entities for all identified mentions in a document, where the nodes are entities, and edges denote their relations. The graph provides highly discriminative semantic signals (e.g., entity relatedness) that are unavailable to local model BIBREF15 . For example (Figure FIGREF1 ), an EL model seemly cannot find sufficient disambiguation clues for the mention England from its surrounding words, unless it utilizes the coherence information of consistent topic “cricket\" among adjacent mentions England, Hussain, and Essex. Although the global model has achieved significant improvements, its limitation is threefold:\nTo mitigate the first limitation, recent EL studies introduce neural network (NN) models due to its amazing feature abstraction and generalization ability. In such models, words/entities are represented by low dimensional vectors in a continuous space, and features for mention as well as candidate entities are automatically learned from data BIBREF4 . However, existing NN-based methods for EL are either local models BIBREF16 , BIBREF17 or merely use word/entity embeddings for feature extraction and rely on another modules for collective disambiguation, which thus cannot fully utilize the power of NN models for collective EL BIBREF18 , BIBREF19 , BIBREF20 .\nThe second drawback of the global approach has been alleviated through approximate optimization techniques, such as PageRank/random walks BIBREF21 , graph pruning BIBREF22 , ranking SVMs BIBREF23 , or loopy belief propagation (LBP) BIBREF18 , BIBREF24 . However, these methods are not differentiable and thus difficult to be integrated into neural network models (the solution for the first limitation).\nTo overcome the third issue of inadequate training data, BIBREF17 has explored a massive amount of hyperlinks in Wikipedia, but these potential annotations for EL contain much noise, which may distract a naive disambiguation model BIBREF6 .\nIn this paper, we propose a novel Neural Collective Entity Linking model (NCEL), which performs global EL combining deep neural networks with Graph Convolutional Network (GCN) BIBREF25 , BIBREF26 that allows flexible encoding of entity graphs. It integrates both local contextual information and global interdependence of mentions in a document, and is efficiently trainable in an end-to-end fashion. Particularly, we introduce attention mechanism to robustly model local contextual information by selecting informative words and filtering out the noise. On the other hand, we apply GCNs to improve discriminative signals of candidate entities by exploiting the rich structure underlying the correct entities. To alleviate the global computations, we propose to convolute on the subgraph of adjacent mentions. Thus, the overall coherence shall be achieved in a chain-like way via a sliding window over the document. To the best of our knowledge, this is the first effort to develop a unified model for neural collective entity linking.\nIn experiments, we first verify the efficiency of NCEL via theoretically comparing its time complexity with other collective alternatives. Afterwards, we train our neural model using collected Wikipedia hyperlinks instead of dataset-specific annotations, and perform evaluations on five public available benchmarks. The results show that NCEL consistently outperforms various baselines with a favorable generalization ability. Finally, we further present the performance on a challenging dataset WW BIBREF19 as well as qualitative results, investigating the effectiveness of each key module.\nAlthough the global model has achieved significant improvements, its limitation is threefold: 1.The global approach suffers from the data sparsity issue of unseen words/entities, and the failure to induce underlying discriminative features for EL. 2.The joint inference mechanism in the global approach leads to expensive computations, especially when the entity graph may contain hundreds of nodes in case of long documents. 3.The annotated EL training data is usually expensive to obtain or only available in narrow domains, which results in possible overfitting issue or domain bias.",

Scheduled for the first full week of April, the Masters is the first major of the year, and unlike the others, it is always held at the same location, Augusta National Golf Club, a private course in the city of Augusta, Georgia, in the southeastern United States.\n\nThe Masters was started by amateur champion Bobby Jones and investment banker Clifford Roberts. After his grand slam in 1930, Jones acquired the former plant nursery and co-designed Augusta National with course architect Alister MacKenzie. First played 89 years ago in 1934, the tournament is an official money event on the PGA Tour, the European Tour, and the Japan Golf Tour. The field of players is smaller than those of the other major championships because it is an invitational event, held by the Augusta National Golf Club.\n\nThe tournament has a number of traditions. Since 1949, a green jacket has been awarded to the champion, who must return it to the clubhouse one year after his victory, although it remains his personal property and is stored with other champions' jackets in a specially designated cloakroom. In most instances, only a first-time and currently reigning champion may remove his jacket from the club grounds. A golfer who wins the event multiple times uses the same green jacket awarded upon his initial win (unless they need to be re-fitted with a new jacket). The Champions Dinner, inaugurated by Ben Hogan in 1952, is held on the Tuesday before each tournament, and is open only to past champions and certain board members of the Augusta National Golf Club. Beginning in 1963, legendary golfers, usually past champions, have hit an honorary tee shot on the morning of the first round to commence play. These have included Fred McLeod, Jock Hutchinson, Gene Sarazen, Sam Snead, Byron Nelson, Arnold Palmer, Jack Nicklaus, Gary Player, Lee Elder, and Tom Watson.

        "question": "What is the concept of a good life according to Socrates and Aristotle, and what are the components that contribute to it? Is a good life innate or learned, and can anyone achieve it?",
        "evidence": "",
        "answer": "One of the most tantalizing and theorized about topics is that of the meaning of life and how to live a “good” one. It is human nature to explain the unknown and create explanations for the way the world works; throughout history philosophers have come to their own conclusions on why some lives are good and others are not. Two key figures that lend insight in these respects are Socrates in Plato’s The Apology, and Aristotle in Nicomachean Ethics. A seemingly simple concept quickly devolves into a confusing and complex web of components that only together in the right proportions lend each man or woman a full good life. In order to discuss the way in which we are to lead a good life we must first discuss the differing factors that contribute to the definition of good in the eyes of Socrates and Aristotle. What are the components of the concept of good? Is it innate or learned? Can it be purchased? Is it temporary or is it eternal? Does it apply to one’s self or a community as a whole? Does one conduct oneself to be good? How Is a good life given by the gods or earned by humans? And although there is no definitive answer to any of these questions, in both author’s texts living a good life comes down to the choices you make and how they compare to the definition of good you subscribe to. Socrates and Aristotle use words such as virtue, courage, happiness, and intelligence to describe their versions of the path you take to reach a good life, and all are important, but the main driver of a good life is one’s ability to find the proper equilibrium between\nDahlke 1\n each of their characteristics that lend towards the development of a commonly defined good life.\nTheorizing on how to live a good life leads to the necessity of defining what a good life is and the components that make it up. Aristotle theorized in Nicomachean Ethics that the idea of virtue, or excellence, can be an overarching theme for the components that make up the highest “good”, the good that is an endpoint or product encompassing the entire life before it. And the development of virtue lies within a midpoint between too much and too little of any emotion, action or characteristic.\n... it is in emotions and actions that excess, deficiency and the median are found. Thus we can experience fear confidence, desire, anger, pity and generally any kind of pleasure and pain either too much or too little, and in either case not properly. But to experience all this at the right time, towards the right objects, towards the right people, for the right reason, and in the right manner — that is the median and the best course, the course that is a mark of virtue. (Aristotle. Bk. 2, pg. 43)\nAnd still, even with the most precise definition Aristotle or Socrates gives there is a great amount of ambiguity. While some characteristics or actions are classified as inherently good or bad Aristotle theorizes that simply over exercising the usage of one or two characteristics doesn’t mean you are a good person living a good life. But rather, he states that there is a median usage point between the extrema of never and always that contributes to virtue, and then a good life. Where that point is is still unknown, partly due to the infinite situational differences one person can have versus another person\nDahlke 2\n\n during their lifetime and partly due to the complexity and magnitude of the variables that contribute to the person as a whole. However, Aristotle goes into a few overarching descriptors of his definition of a virtuous man or woman to help define the median between the two extrema. For example, the median for pleasure and pain is self control, between fear and confidence is courage, and righteous falls between envy and spite.1 These examples shine a light on how to find the middle between two opposing qualities, but do not instruct on how we are to lead a good life. While definitively defining the idea of good is complex the framework of thought to use when faced with daily decisions Aristotle provides allows for the discussion on how to live a good life.\nCreating a structured plan for how to live a good life brings about the question can anyone live a good life? Furthermore, are the segments that complete virtue innate or are they learned? Aristotle delves into two schools of thought, the first being that there are some characteristics that born with can impede or halt one’s quest for moral virtue, and secondly, that one develops these traits over time and through ritual habit. The latter, he describes in analogy, “Similarly, we become just by the practice of just actions, self-controlled by exercising self-control, and courageous by performing acts of courage.” (Aristotle. Bk. 2, pg. 34) In other words, one becomes virtuous by continually being virtuous. Therefore, one finds oneself in a good life when one habitually lives within the middle of all opposing qualities. While not everyone in a society will live a good life, everyone within a society can live a good life. At this point it is important to\n1 Examples given in Book II Ch. 7 - Nicomachean Ethics\nDahlke 3\n \n refer back to the definition of what a good life is, it does not mean success, fame or wealth, but rather practicing the combination of elements that create virtue.\nWhile some qualities like virtue are relatively undisputed as good, wealth is a heavily debated part of a good life. Both Aristotle and Socrates agree that wealth is not an indicator of a good life but their thought differs when it comes to the part money plays in the development of such a life. While Aristotle believes wealth is a necessity for aspects of a virtuous life, Socrates believes that wealth is only a byproduct of a good life. Aristotle does concede to saying that, “wealth is not the good which we are trying to find, for it is only useful, i.e., it is a means to something else.” (Aristotle. Bk. 1, pg. 9) Otherwise saying that while wealth is not the end goal and is meaningless when thinking of one’s worth, it is helpful in the creation of a good life. On the other hand, Socrates writes of wealth as something that does not create excellence and at times can even inhibit it’s development. In The Apology Socrates says to the jury, “Wealth does not bring about excellence, but excellence brings about wealth and all other public and private blessings for men.” (Plato. 30b) While this quote is taken out of the context of a defensive argument, it still holds Socrates’ beliefs on wealth. He, an impoverished man, does not find the same value in money as sophists like Aristotle, and while defending his choice to not charge a fee to the pupils that followed his philosophical thought like other sophists did, he said that he is here at the service to god. Both theories on wealth’s role in a good life are important to consider. Does wealth lead to corruption and poverty to a more sinful life? Wealth, similarly to fear, needs a median. As Aristotle describes fear, too little is being reckless, while too much is being cowardly. In wealth the same thought\nDahlke 4\n\n can be applied, too little creates extreme poverty which distracts from living a virtuous life and too much can create different distractions that lead to the same result.\nAnother contesting theory is that of the length in which “goodness” lasts. When defining a good life, it is important to think about when you can use good as a descriptor. If goodness in reference to one’s life lasts forever then the term is permanent and can be applied throughout one's life. If on the contrary, goodness comes and goes throughout life the term can only be used temporarily or in posterity noting one’s life as a whole. Socrates, after the announcement of his execution states, “a good man cannot be harmed either in life or death, and that his affairs are not neglected by the gods.” (Plato. 41 c-d) Lending the idea that a good man or woman living a good life is continuous and permanent, throughout life and death. However, Aristotle argues that since a good life is a sum of smaller goods, to use the term to describe someone's life, it must come at the end of their life, looking at it as a whole. After describing smaller goals and endpoints he goes further and says, “The highest good, on the other hand, must be something final” (Aristotle. Bk. 1 pg. 14) Stating that while there are different branches of a good life, virtuous behavior is not a constant and therefore you cannot give a description to their life as a whole until it’s end. Socrates’ arguments on the length of goodness are rather naive, seeing as people change over time, only with the entire information of their lives can one make a claim as to whether or not they had a good life.\nIn summary, the two different views on how we are to live a good life together provide insight and theory into the subject but neither provides a complete instruction on doing so. Socrates, as written down by Plato, describes his own life which he\nDahlke 5\n\nconsiders to be a virtuous one and Aristotle provides a philosophical theory behind how to live in a virtuous way with the end goal of happiness or in other words a good life. The closest we can get to understanding how to live a good life is by understanding what makes up a good life, and even this is subjective. One person’s views on what a virtuous life means can differ greatly from the next depending on where they lived, their religious beliefs, or social status. These variances result in many different guides to and definitions of a good life. Within all the different viewpoints, a concept introduced in Nicomachean Ethics that can be widely accepted is that within someone’s life there is a median point between each of their emotions, actions and characteristics that create virtue and lead towards a good life.",

Microsoft's best-known software products are the Windows line of operating systems, the Microsoft Office suite, and the Internet Explorer and Edge web browsers. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface lineup of touchscreen personal computers. Microsoft ranked No. 14 in the 2022 Fortune 500 rankings of the largest United States corporations by total revenue; it was the world's largest software maker by revenue as of 2022. It is considered as one of the Big Five American information technology companies, alongside Alphabet (parent company of Google), Amazon, Apple, and Meta (formerly Facebook).\n\nMicrosoft was founded by Bill Gates and Paul Allen on April 4, 1975, to develop and sell BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Windows. The company's 1986 initial public offering (IPO), and subsequent rise in its share price, created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions, their largest being the acquisition of LinkedIn for $26.2 billion in December 2016, followed by their acquisition of Skype Technologies for $8.5 billion in May 2011.\n\nAs of 2015, Microsoft is market-dominant in the IBM PC compatible operating system market and the office software suite market, although it has lost the majority of the overall operating system market to Android.

        "evidence": "Medical providers across the United States are required to document clinical visits in the Electronic Health Records. This need for documentation takes up a disproportionate amount of their time and attention, resulting in provider burnout BIBREF0, BIBREF1. One study found that full-time primary care physicians spent about 4.5 hours of an 11-hour workday interacting with the clinical documentation systems, yet were still unable to finish their documentation and had to spend an additional 1.4 hours after normal clinical hours BIBREF2.\nSpeech and natural language processing are now sufficiently mature that there is considerable interest, both in academia and industry, to investigate how these technologies can be exploited to simplify the task of documentation, and to allow providers to dedicate more time to patients. While domain-specific automatic speech recognition (ASR) systems that allow providers to dictate notes have been around for a while, recent work has begun to address the challenges associated with generating clinical notes directly from speech recordings. This includes inducing topic structure from conversation data, extracting relevant information, and clinical summary generation BIBREF3. In one recent work, authors outlined an end-to-end system; however, the details were scant without empirical evaluations of their building blocks BIBREF4. One of the simplistic approaches uses a hand crafted finite state machine based grammar to locate clinical entities in the ASR transcripts and map them to canonical clinical terms BIBREF5. This seems to perform well in a narrowly scoped task. A more ambitious approach mapped ASR transcripts to clinical notes by adopting a machine translation approach BIBREF6. However this performed poorly. To address the difficulty in accessing clinical data, researchers have experimented with synthetic data to develop a system for documenting nurse-initiated telephone conversations for congestive heart failure patients who are undergoing telemonitoring after they have been discharged from the hospital BIBREF7. In their task, a question-answer based model achieved an F-score of 0.80. This naturally raises the question of how well state-of-art techniques will perform in helping the broader population of clinicians such as primary care providers.\nOne might expect that the task of extracting clinical concepts from audio faces challenges similar to the domain of unstructured clinical texts. In that domain, one of the earliest public-domain tasks is the i2b2 relations challenge, defined on a small corpus of written discharge summaries consisting of 394 reports for training, 477 for test, and 877 for evaluation BIBREF8. Given the small amount of training data, not surprisingly, a disproportionately large number of teams fielded rule-based systems. Conditional random field-based (CRF) systems BIBREF9 however did better even with the limited amount of training data BIBREF10. Other i2b2/n2c2 challenges focused on coreference resolution BIBREF11, temporal relation extraction BIBREF12, drug event extraction BIBREF13 on medical records, and extracting family history BIBREF14. Even though the text was largely unstructured, they benefited from punctuation and capitalization, section headings and other cues in written domain which are unavailable in audio to the same extent.\nWith the goal of creating an automated medical scribe, we broke down the task into modular components, including ASR and speaker diarization which are described elsewhere BIBREF15. In this work, we investigate the task of extracting relevant clinical concepts from transcripts. Our key contributions include: (i) defining three tasks – the Medications Task, the Symptoms Task, and the Conditions Task along with principles employed in developing the annotation guidelines for them (Section SECREF2); (ii) measuring the label quality using inter-labeler agreements and refining the quality iteratively (Section SECREF3), (iii) evaluating the performance of the state-of-the-art models on these tasks (Section SECREF4), and (iv) a comprehensive analysis of the performance of the models including manual error categorization (Section SECREF5).

The statue had an inscription identifying it as an image of Helios, the god of the sun and local deity to Rhodes. In the wider Ancient Greek world Helios would likely be identified more readily as Apollo. The statue may have been made in the likeness of Alexander the Great's official image. This would have served to represent a bond between Rhodes and Alexandria with Alexander's image serving as the founder of the Egyptian city. Support for this idea comes from the fact that the Colossus was made to celebrate Rhodes' victory over a siege. This victory was largely facilitated by Ptolemy from Alexandria, and Alexandria is also a likely source for the funds of the ambitious project. The artist Chares of Lindos would also have been well selected to achieve this double representation. He was local to the island of Rhodes (Lindos is another city on the same island) and would have been familiar with images of Helios. He was also the student of Lysippos who was the exclusive personal sculptor to Alexander the Great during his lifetime, and so Chares would have also been uniquely knowledgeable about the image of Alexander. Some but not all scholars argue for the Colossus to be understood as an image of Alexander posing as Helios that would be seen by the people of Rhodes as their local deity but seen by the people of Alexandria as their founder. The Statue of Liberty built by France and gifted to the USA was partially modeled after the Colossus and is similarly possible to read as a celebration of American independence and also a reference to one the three values Liberté, Égalité and Fraternité central to French identity.",

Following related work by BIBREF21, BIBREF24, we use Trueskill BIBREF25 to cluster systems into equivalently rated groups according to their partial relative rankings. The results in Table TABREF36 show that the highest rated systen is Alley, a purpose build bot for online language learning. Alley produces “polite refusal” (2b) - the top ranked strategy - 31% of the time. Comparatively, commercial systems politely refuse only between 17% (Cortana) and 2% (Alexa). Most of the time commercial systems tend to “play along” (3a), joke (3b) or don't know how to answer (1e) which tend to receive lower ratings, see Figure FIGREF38. Rule-based systems most often politely refuse to answer (2b), but also use medium ranked strategies, such as deflect (2c) or chastise (2d). For example, most of Eliza's responses fall under the “deflection” strategy, such as “Why do you ask?”. Data-driven systems rank low in general. Neuralconvo and Cleverbot are the only ones that ever politely refuse and we attribute their improved ratings to this. In turn, the “clean” seq2seq often produces responses which can be interpreted as flirtatious (44%), and ranks similarly to Annabelle Lee and Laurel Sweet, the only adult bots that politely refuses ( 16% of the time). Ritter:2010:UMT:1857999.1858019's IR approach is rated similarly to Capt Howdy and both produce a majority of retaliatory (2e) responses - 38% and 58% respectively - followed by flirtatious responses.

If the language of a piece of text is known then the appropriate downstream models like parts of speech taggers and language models can be applied as required.\nLID is further also an important step in harvesting scarce language resources. Harvested data can be used to bootstrap more accurate LID models and in doing so continually improve the quality of the harvested data. Availability of data is still one of the big roadblocks for applying data driven approaches like supervised machine learning in developing countries.\nHaving 11 official languages of South Africa has lead to initiatives (discussed in the next section) that have had positive effect on the availability of language resources for research. However, many of the South African languages are still under resourced from the point of view of building data driven models for machine comprehension and process automation.\nTable TABREF2 shows the percentages of first language speakers for each of the official languages of South Africa. These are four conjunctively written Nguni languages (zul, xho, nbl, ssw), Afrikaans (afr) and English (eng), three disjunctively written Sotho languages (nso, sot, tsn), as well as tshiVenda (ven) and Xitsonga (tso). The Nguni languages are similar to each other and harder to distinguish. The same is true of the Sotho languages.\nThis paper presents a hierarchical naive Bayesian and lexicon based classifier for LID of short pieces of text of 15-20 characters long. The algorithm is evaluated against recent approaches using existing test sets from previous works on South African languages as well as the Discriminating between Similar Languages (DSL) 2015 and 2017 shared tasks.\nSection SECREF2 reviews existing works on the topic and summarises the remaining research problems. Section SECREF3 of the paper discusses the proposed algorithm and Section SECREF4 presents comparative results.\nThis paper presents a hierarchical naive Bayesian and lexicon based classifier for LID of short pieces of text of 15-20 characters long.",

Our RoBERTa baseline performs quite well on HotpotQA (77.0 F1), despite processing each paragraph separately, which prohibits inter-paragraph reasoning. The result is in line with prior work which found that a version of our baseline QA model using BERT BIBREF26 does well on HotpotQA by exploiting single-hop reasoning shortcuts BIBREF21. We achieve significant gains over our strong baseline by leveraging decompositions from our best decomposition model, trained with USeq2Seq on FastText pseudo-decompositions; we find a 3.1 F1 gain on the original dev set, 11 F1 gain on the multi-hop dev set, and 10 F1 gain on the out-of-domain dev set. Unsupervised decompositions even match the performance of using (within our pipeline) supervised and heuristic decompositions from DecompRC (i.e., 80.1 vs. 79.8 F1 on the original dev set).\nWe fine-tune a pre-trained model to take a question and several paragraphs and predicts the answer, similar to the single-hop QA model from BIBREF21. The model computes a separate forward pass on each paragraph (with the question). For each paragraph, the model learns to predict the answer span if the paragraph contains the answer and to predict “no answer” otherwise. We treat yes and no predictions as spans within the passage (prepended to each paragraph), as in BIBREF22 on HotpotQA. During inference, for the final softmax, we consider all paragraphs as a single chunk. Similar to BIBREF23, we subtract a paragraph's “no answer” logit from the logits of all spans in that paragraph, to reduce or increase span probabilities accordingly. In other words, we compute the probability $p(s_p)$ of each span $s_p$ in a paragraph $p \\in \\lbrace 1, \\dots , P \\rbrace $ using the predicted span logit $l(s_p)$ and “no answer” paragraph logit $n(p)$ as follows:\nWe use $\\textsc {RoBERTa}_{\\textsc {LARGE}}$ BIBREF24 as our pre-trained initialization.

        "answer": "In 1725, Basile Bouchon invented punch cards, which communicate information in a machine language. The punched holes communicated a sequence of instructions and acted as on/off switches for devices such as self-playing pianos or looms. About a century later, Charles Babbage invented the first mechanical calculator, the Difference Engine using punch card instructions. Herman Hollerith continued developing this idea and made the Analytical Engine a reality by using punch holes to be a sequence of instructions and also store the instruction data on the device. In 1890, he developed a punch card data processing system for the US Census and went on to form the Tabulating Machine Company in 1896, later renamed International Business Machines Corporation (IBM). By the 1950s punch cards were being used regularly by the US government and industry.  Even today, punch cards are still used in standardized tests and voting ballots. Initially invented by Fritz Pfleumer in 1928, magnetic storage gradually replaced punch cards in the 1960s.  By 1965, Mohawk Data Sciences Corporation sold a key-to-tape magnetic tape device that was specifically marketed to replace the punch card. Cassette tapes started to become commonly used for most computers in the 70s and 80s.

This is a valuable solution for collecting dialogues in domains where specific expertise is required and the cost of training capable Wizards is high. We required fine-grained control over the Wizard interface so as to be able to generate more directed dialogues for specialised domains, such as emergency response for offshore facilities. By providing the Wizard with several dialogue options (aside from free text), we guided the conversation and could introduce actions that change an internal system state. This proposes several advantages:\nA guided dialogue allows for set procedures to be learned and reduces the amount of data needed for a machine learning model for dialogue management to converge.\nProviding several dialogue options to the Wizard increases the pace of the interaction and allows them to understand and navigate more complex scenarios.\nDialogue structure: we introduced structured dialogues through a Finite State Machine (FSM) that controls the current dialogue state and offers multiple suitable and relevant state transitions (actions) to the Wizard depending on the point in the interaction, the state of the world and the history. A graph of dialogue states, transitions and utterances is loaded when the system is initialised, and each chat room has its own dialogue state, which changes through actions.\nThe dialogue structure for the Emergency Assistant (the Wizard) followed a dialogue flow previously used for the original lab-based Wizard-of-Oz study BIBREF4 but which was slightly modified and simplified for this crowdsourced data collection. In addition to the transitions that the FSM provides, there are other fixed dialogue options always available such as “Hold on, 2 seconds”, “Okay” or “Sorry, can you repeat that?” as a shortcut for commonly used dialogue acts, as well as the option to type a message freely.\nThe dialogue has several paths to reach the same states with varying levels of Operator control or engagement that enriched the heterogeneity of conversations. The Emergency Assistant dialogue options show various speaking styles, with a more assertive tone (“I am sending Husky 1 to east tower”) or others with more collaborative connotations (“Which robot do you want to send?” or “Husky 1 is available to send to east tower”). Refer to BIBREF4 for more details. Furthermore, neither participants were restricted in the number of messages that they could send and we did not require a balanced number of turns between them. However, there were several dialogue transitions that required an answer or authorisation from the Operator, so the FSM would lock the dialogue state until the condition was met.

        "evidence": "For the implementation of our neural network, we used pytorch-pretrained-bert library containing the pre-trained BERT model, text tokenizer, and pre-trained WordPiece. As the implementation environment, we use Google Colaboratory tool which is a free research tool with a Tesla K80 GPU and 12G RAM. Based on our experiments, we trained our classifier with a batch size of 32 for 3 epochs. The dropout probability is set to 0.1 for all layers. Adam optimizer is used with a learning rate of 2e-5. As an input, we tokenized each tweet with the BERT tokenizer. It contains invalid characters removal, punctuation splitting, and lowercasing the words. Based on the original BERT BIBREF11, we split words to subword units using WordPiece tokenization. As tweets are short texts, we set the maximum sequence length to 64 and in any shorter or longer length case it will be padded with zero values or truncated to the maximum length.\nWe consider 80% of each dataset as training data to update the weights in the fine-tuning phase, 10% as validation data to measure the out-of-sample performance of the model during training, and 10% as test data to measure the out-of-sample performance after training. To prevent overfitting, we use stratified sampling to select 0.8, 0.1, and 0.1 portions of tweets from each class (racism/sexism/neither or hate/offensive/neither) for train, validation, and test. Classes' distribution of train, validation, and test datasets are shown in Table TABREF16.\nAs it is understandable from Tables TABREF16(classdistributionwaseem) and TABREF16(classdistributiondavidson), we are dealing with imbalance datasets with various classes’ distribution. Since hate speech and offensive languages are real phenomena, we did not perform oversampling or undersampling techniques to adjust the classes’ distribution and tried to supply the datasets as realistic as possible. We evaluate the effect of different fine-tuning strategies on the performance of our model. Table TABREF17 summarized the obtained results for fine-tuning strategies along with the official baselines. We use Waseem and Hovy BIBREF5, Davidson et al. BIBREF9, and Waseem et al. BIBREF10 as baselines and compare the results with our different fine-tuning strategies using pre-trained BERTbase model. The evaluation results are reported on the test dataset and on three different metrics: precision, recall, and weighted-average F1-score. We consider weighted-average F1-score as the most robust metric versus class imbalance, which gives insight into the performance of our proposed models. According to Table TABREF17, F1-scores of all BERT based fine-tuning strategies except BERT + nonlinear classifier on top of BERT are higher than the baselines. Using the pre-trained BERT model as initial embeddings and fine-tuning the model with a fully connected linear classifier (BERTbase) outperforms previous baselines yielding F1-score of 81% and 91% for datasets of Waseem and Davidson respectively. Inserting a CNN to pre-trained BERT model for fine-tuning on downstream task provides the best results as F1- score of 88% and 92% for datasets of Waseem and Davidson and it clearly exceeds the baselines. Intuitively, this makes sense that combining all pre-trained BERT layers with a CNN yields better results in which our model uses all the information included in different layers of pre-trained BERT during the fine-tuning phase. This information contains both syntactical and contextual features coming from lower layers to higher layers of BERT.\nFor the implementation of our neural network, we used pytorch-pretrained-bert library containing the pre-trained BERT model, text tokenizer, and pre-trained WordPiece.",

Swift wrote the song with its producers Max Martin and Shellback. The album track is a pop song with stomping drums. A hip hop remix of \"Bad Blood\", featuring American rapper Kendrick Lamar and additional production by Ilya, was released as the fourth single from 1989 on May 17, 2015, by Big Machine and Republic Records.\n\nThe lyrics are about feelings of betrayal by a close friend. Upon the album's release, critics expressed mixed opinions about \"Bad Blood\", with some complimenting Swift's defiant attitude and dubbing it an album highlight, while others criticized its production and lyrics. The remixed single was praised for the reworked instrumentation and Lamar's verses, which others considered to be out of place on a pop song. Media outlets speculated that American singer Katy Perry is the subject of the song. The remix received a Grammy nomination for Best Pop Duo/Group Performance.\n\n\"Bad Blood\" was supported by a high-budget music video directed by Joseph Kahn and produced by Swift. It featured an ensemble cast consisting of many singers, actresses and fashion models, which received wide media coverage. Critics praised the video for its cinematic and futuristic visuals inspired by neo-noir styles. It won a Grammy Award for Best Music Video, and two MTV Video Music Awards for the Video of the Year and Best Collaboration. Commercially, \"Bad Blood\" reached number one in Australia, Canada, New Zealand, and Scotland, as well as the United States, where it topped the Billboard Hot 100, Adult Top 40 and Mainstream Top 40 charts.

The 21st century has brought us the rapid development of media, especially in the internet ecosystem. This change has caused the transfer of many areas of our lives to virtual reality. New forms of communication have been established. Their development has created the need for analysis of related data. Nowadays, unstructured information is available in digital form, but how can we analyse and summarise billions of newly created texts that appear daily on the internet? Natural language analysis techniques, statistics and machine learning have emerged as tools to help us. In recent years, particular attention has focused on sentiment analysis. This area is defined as the study of opinions expressed by people as well as attitudes and emotions about a particular topic, product, event, or person. Sentiment analysis determines the polarisation of the text. It answers the question as to whether a particular text is a positive, negative, or neutral one.\nOur goal is to build a comprehensive set of techniques for preparing and analysing texts containing opinions and generating user-friendly descriptive reports in natural language - Figure FIGREF1 . In this paper, we describe briefly the whole workflow and present a prototype implementation. Currently, existing solutions for sentiment annotation offer mostly analysis on the level of entire documents, and if you go deeper to the level of individual product features, they are only superficial and poorly prepared for the analysis of large volumes of data. This can especially be seen in scientific articles where the analysis is carried out on a few hundred reviews only. It is worth mentioning that this task is extremely problematic because of the huge diversity of languages and the difficulty of building a single solution that can cover all the languages used in the world. Natural language analysis often requires additional pre-processing steps, especially at the stage of preparing the data for analysis, and steps specific for each language. Large differences can be seen in the analysis of the Polish language (a highly inflected language) and English (a grammatically simpler one). We propose a solution that will cover several languages, however in this prototype implementation we focused on English texts only.\nIn this paper, we present analysis and workflow inspired by the work of Joty, Carenini and Ng BIBREF0 . We experimented with several methods in order to validate aspect-based sentiment analysis approaches and in the next steps we want to customise our implementation for the Polish language.\nThe paper presents in Section SECREF1 an introduction to sentiment analysis and its importance in business, then in Section SECREF2 - related work from rhetorical and sentiment analysis areas is presented. Section SECREF3 covers description of our method. Implementation and the dataset are described in Section SECREF4 . Section SECREF5 refers to the results.

Potential benefits of TENS treatment include the safety, relative low cost, the ability to self-administer, and availability over the counter without a prescription. In principle, an adequate intensity of stimulation is necessary to achieve pain relief with TENS.

        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce.",

Twitter data is particularly interesting because of its peculiar nature where people convey messages in short sentences using hashtags, emoticons, emojis etc. In addition, each tweet has meta data like location and language used by the sender. It's challenging to analyze this data because the tweets might not be grammatically correct and the users tend to use informal and slang words all the time.

        "evidence": "Dehumanization is a pernicious psychological process that often leads to extreme intergroup bias, hate speech, and violence aimed at targeted social groups. Despite these serious consequences and the wealth of available data, dehumanization has not yet been computationally studied on a large scale. Drawing upon social psychology research, we create a computational linguistic framework for analyzing dehumanizing language by identifying linguistic correlates of salient components of dehumanization. We then apply this framework to analyze discussions of LGBTQ people in the New York Times from 1986 to 2015. Overall, we find increasingly humanizing descriptions of LGBTQ people over time. However, we find that the label homosexual has emerged to be much more strongly associated with dehumanizing attitudes than other labels, such as gay. Our proposed techniques highlight processes of linguistic variation and change in discourses surrounding marginalized groups. Furthermore, the ability to analyze dehumanizing language at a large scale has implications for automatically detecting and understanding media bias as well as abusive language online.\nWe then apply this framework to analyze discussions of LGBTQ people in the New York Times from 1986 to 2015.",

        "question": "In their model, what task is joined to detect fake news?",
        "answer": "Stance detection task.",
        "evidence": "In recent years, the proliferation of fake news with various content, high-speed spreading, and extensive influence has become an increasingly alarming issue. A concrete instance was cited by Time Magazine in 2013 when a false announcement of Barack Obama's injury in a White House explosion “wiped off 130 Billion US Dollars in stock value in a matter of seconds\". Other examples, an analysis of the US Presidential Election in 2016 BIBREF0 revealed that fake news was widely shared during the three months prior to the election with 30 million total Facebook shares of 115 known pro-Trump fake stories and 7.6 million of 41 known pro-Clinton fake stories. Therefore, automatically detecting fake news has attracted significant research attention in both industries and academia.\nMost existing methods devise deep neural networks to capture credibility features for fake news detection. Some methods provide in-depth analysis of text features, e.g., linguistic BIBREF1, semantic BIBREF2, emotional BIBREF3, stylistic BIBREF4, etc. On this basis, some work additionally extracts social context features (a.k.a. meta-data features) as credibility features, including source-based BIBREF5, user-centered BIBREF6, post-based BIBREF7 and network-based BIBREF8, etc. These methods have attained a certain level of success. Additionally, recent researches BIBREF9, BIBREF10 find that doubtful and opposing voices against fake news are always triggered along with its propagation. Fake news tends to provoke controversies compared to real news BIBREF11, BIBREF12. Therefore, stance analysis of these controversies can serve as valuable credibility features for fake news detection.\nThere is an effective and novel way to improve the performance of fake news detection combined with stance analysis, which is to build multi-task learning models to jointly train both tasks BIBREF13, BIBREF14, BIBREF15. These approaches model information sharing and representation reinforcement between the two tasks, which expands valuable features for their respective tasks. However, prominent drawback to these methods and even typical multi-task learning methods, like the shared-private model, is that the shared features in the shared layer are equally sent to their respective tasks without filtering, which causes that some useless and even adverse features are mixed in different tasks, as shown in Figure FIGREF2(a). By that the network would be confused by these features, interfering effective sharing, and even mislead the predictions.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure FIGREF2(b)) to detect fake news by joining stance detection task. Specifically, we introduce a selected sharing layer into each task after the shared layer of the model for filtering shared features. The selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks. Besides, to better capture long-range dependencies and improve the parallelism of the model, we apply transformer encoder module BIBREF16 to our model for encoding input representations of both tasks. Experimental results reveal that the proposed model outperforms the compared methods and gains new benchmarks.\nIn summary, the contributions of this paper are as follows:\nWe explore a selected sharing layer relying on gate mechanism and attention mechanism, which can selectively capture valuable shared features between tasks of fake news detection and stance detection for respective tasks.\nThe transformer encoder is introduced into our model for encoding inputs of both tasks, which enhances the performance of our method by taking advantages of its long-range dependencies and parallelism.\nExperiments on two public, widely used fake news datasets demonstrate that our method significantly outperforms previous state-of-the-art methods.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure 1(b)) to detect fake news by joining stance detection task.",

The movement pattern is similar to squatting down, where you want to drop your bottom down towards your ankle. The reason you want your knee and hip to take the impact is because those joints have much bigger range of motion compared to your back so as you hit a bump or mogul, those joints will help absorb the majority of the irregularity in the terrain so your back is not needing to move as much which will help reduce the strain being put on it.",

        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nHence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension.",

        "evidence": "Although the Sun appears to \"rise\" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion caused many cultures to have mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century.\nAstronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon. However, the term sunrise commonly refers to periods of time both before and after this point:\nTwilight, the period in the morning during which the sky is brightening, but the Sun is not yet visible. The beginning of morning twilight is called astronomical dawn.\nThe period after the Sun rises during which striking colors and atmospheric effects are still seen.\nThe timing of sunrise varies throughout the year and is also affected by the viewer's latitude and longitude, altitude, and time zone. These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun, and the Earth and Moon's paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise.\nIn late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.\nVariations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly.\nAccounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.",

        "question": "How are sentence embeddings incorporated into the speech recognition system?",
        "answer": "BERT generates sentence embeddings that represent words in context. These sentence embeddings are merged into a single conversational-context vector that is used to calculate a gated embedding and is later combined with the output of the decoder h to provide the gated activations for the next hidden layer.",
        "evidence": "There exist many word/sentence embeddings which are publicly available. We can broadly classify them into two categories: (1) non-contextual word embeddings, and (2) contextual word embeddings. Non-contextual word embeddings, such as Word2Vec BIBREF1 , GloVe BIBREF39 , fastText BIBREF17 , maps each word independently on the context of the sentence where the word occur in. Although it is easy to use, it assumes that each word represents a single meaning which is not true in real-word. Contextualized word embeddings, sentence embeddings, such as deep contextualized word representations BIBREF20 , BERT BIBREF22 , encode the complex characteristics and meanings of words in various context by jointly training a bidirectional language model. The BERT model proposed a masked language model training approach enabling them to also learn good “sentence” representation in order to predict the masked word.\nIn this work, we explore both types of embeddings to learn conversational-context embeddings as illustrated in Figure 1 . The first method is to use word embeddings, fastText, to generate 300-dimensional embeddings from 10k-dimensional one-hot vector or distribution over words of each previous word and then merge into a single context vector, $e^k_{context}$ . Since we also consider multiple word/utterance history, we consider two simple ways to merge multiple embeddings (1) mean, and (2) concatenation. The second method is to use sentence embeddings, BERT. It is used to a generate single 786-dimensional sentence embedding from 10k-dimensional one-hot vector or distribution over previous words and then merge into a single context vector with two different merging methods. Since our A2W model uses a restricted vocabulary of 10k as our output units and which is different from the external embedding models, we need to handle out-of-vocabulary words. For fastText, words that are missing in the pretrained embeddings we map them to a random multivariate normal distribution with the mean as the sample mean and variance as the sample variance of the known words. For BERT, we use its provided tokenizer to generates byte pair encodings to handle OOV words.\nUsing this approach, we can obtain a more dense, informative, fixed-length vectors to encode conversational-context information, $e^k_{context}$ to be used in next $k$ -th utterance prediction.\nWe use contextual gating mechanism in our decoder network to combine the conversational-context embeddings with speech and word embeddings effectively. Our gating is contextual in the sense that multiple embeddings compute a gate value that is dependent on the context of multiple utterances that occur in a conversation. Using these contextual gates can be beneficial to decide how to weigh the different embeddings, conversational-context, word and speech embeddings. Rather than merely concatenating conversational-context embeddings BIBREF6 , contextual gating can achieve more improvement because its increased representational power using multiplicative interactions.\nFigure 2 illustrates our proposed contextual gating mechanism. Let $e_w = e_w(y_{u-1})$ be our previous word embedding for a word $y_{u-1}$ , and let $e_s = e_s(x^k_{1:T})$ be a speech embedding for the acoustic features of current $k$ -th utterance $x^k_{1:T}$ and $e_c = e_c(s_{k-1-n:k-1})$ be our conversational-context embedding for $n$ -number of preceding utterances ${s_{k-1-n:k-1}}$ . Then using a gating mechanism:\n$$g = \\sigma (e_c, e_w, e_s)$$ (Eq. 15)\nwhere $\\sigma $ is a 1 hidden layer DNN with $\\texttt {sigmoid}$ activation, the gated embedding $e$ is calcuated as\n$$e = g \\odot (e_c, e_w, e_s) \\\\ h = \\text{LSTM}(e)$$ (Eq. 16)\nand fed into the LSTM decoder hidden layer. The output of the decoder $h$ is then combined with conversational-context embedding $e_c$ again with a gating mechanism,\n$$g = \\sigma (e_C, h) \\\\ \\hat{h} = g \\odot (e_c, h)$$ (Eq. 17)\nThen the next hidden layer takes these gated activations, $\\hat{h}$ , and so on.\nContextualized word embeddings, sentence embeddings, such as deep contextualized word representations BIBREF20 , BERT BIBREF22 , encode the complex characteristics and meanings of words in various context by jointly training a bidirectional language model. \nThe second method is to use sentence embeddings, BERT.

        "evidence": "John Emerich Edward Dalberg-Acton, 1st Baron Acton, 13th Marquess of Groppoli, KCVO, DL (10 January 1834 – 19 June 1902), better known as Lord Acton, was an English Catholic historian, politician, and writer. He is best remembered for the remark he wrote in a letter to an Anglican bishop in 1887: \n\n\"Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men…\"\n\nIn 1870, along with his mentor Döllinger, Acton opposed the moves to promulgate the doctrine of papal infallibility in the First Vatican Council, travelling to Rome to lobby against it, ultimately unsuccessfully. Unlike Döllinger, Acton did not become an Old Catholic, and continued attending Mass regularly; he received the last rites on his deathbed. The Catholic Church did not try to force his hand. It was in this context that, in a letter he wrote to scholar and ecclesiastic Mandell Creighton, dated April 1887, Acton made his most famous pronouncement:\n\nBut if we might discuss this point until we found that we nearly agreed, and if we do agree thoroughly about the impropriety of Carlylese denunciations and Pharisaism in history, I cannot accept your canon that we are to judge Pope and King unlike other men, with a favourable presumption that they did no wrong. If there is any presumption it is the other way, against the holders of power, increasing as the power increases. Historic responsibility has to make up for the want of legal responsibility. Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority, still more when you superadd the tendency or the certainty of corruption by authority. There is no worse heresy than that the office sanctifies the holder of it. That is the point at which the negation of Catholicism and the negation of Liberalism meet and keep high festival, and the end learns to justify the means. You would hang a man of no position like Ravaillac; but if what one hears is true, then Elizabeth asked the gaoler to murder Mary, and William III of England ordered his Scots minister to extirpate a clan. Here are the greatest names coupled with the greatest crimes; you would spare those criminals, for some mysterious reason. I would hang them higher than Haman, for reasons of quite obvious justice, still more, still higher for the sake of historical science.\n\nThenceforth he steered clear of theological polemics. He devoted himself to reading, study and congenial society. With all his capacity for study, he was a man of the world and a man of affairs, not a bookworm. His only notable publications were a masterly essay in the Quarterly Review of January 1878 on \"Democracy in Europe;\" two lectures delivered at Bridgnorth in 1877 on \"The History of Freedom in Antiquity\" and \"The History of Freedom in Christianity\"—these last the only tangible portions put together by him of his long-projected \"History of Liberty;\" and an essay on modern German historians in the first number of the English Historical Review, which he helped to found (1886). After 1879 he divided his time between London, Cannes, and Tegernsee in Bavaria, enjoying and reciprocating the society of his friends. In 1872 he had been given the honorary degree of Doctor of Philosophy by the University of Munich; in 1888 Cambridge gave him the honorary degree of Doctor of Laws, and in 1889 Oxford the Doctor of Civil Law; and in 1890 he received the high academic accolade of being made a fellow of All Souls College, Oxford.",

We take the first 80% of this data set for our training set and the last 20% for the validation set. Since the test set is also hand-labeled we found that the 645 articles are much more representative of the final test set than the articles labeled by publisher. The model's performance on articles labeled by publisher was not much above chance level.\nOur first experiment was checking the importance of pre-training. We pre-trained BERT-base on the 600,000 articles without labels by using the same Cloze task BIBREF5 that BERT had originally used for pre-training. We then trained the model on sequence lengths of 100, 250 and 500. The accuracy for each sequence length after 100 epochs is shown in TABREF7 and is labeled as UP (unsupervised pre-training). The other column shows how well BERT-base trained without pre-training. We found improvements for lower sequence lengths, but not at 500 word pieces. Since the longer chunk should have been more informative, and since our hand-labeled training set only contained 516 articles, this likely indicates that BERT experiences training difficulty when dealing with long sequences on such a small dataset.

        "answer": "By Must-Link and Cannot-Link primitives represented by a Dirichlet Forest prior.",
        "evidence": "Topic modeling approaches are unsupervised statistical algorithms that usually considers each document as a \"bag of words\". There were several attempts to enrich word-based topic models (=unigram topic models) with additional prior knowledge or multiword expressions.\nAndrzejewski et al. BIBREF5 incorporated knowledge by Must-Link and Cannot-Link primitives represented by a Dirichlet Forest prior. These primitives were then used in BIBREF6 , where similar words are encouraged to have similar topic distributions. However, all such methods incorporate knowledge in a hard and topic-independent way, which is a simplification since two words that are similar in one topic are not necessarily of equal importance for another topic.\nXie et al. BIBREF7 proposed a Markov Random Field regularized LDA model (MRF-LDA), which utilizes the external knowledge to improve the coherence of topic modeling. Within a document, if two words are labeled as similar according to the external knowledge, their latent topic nodes are connected by an undirected edge and a binary potential function is defined to encourage them to share the same topic label. Distributional similarity of words is calculated beforehand on a large text corpus.\nIn BIBREF8 , the authors gather so-called lexical relation sets (LR-sets) for word senses described in WordNet. The LR-sets include synonyms, antonyms and adjective-attribute related words. To adapt LR-sets to a specific domain corpus and to remove inappropriate lexical relations, the correlation matrix for word pairs in each LR-set is calculated. This matrix at the first step is used for filtrating inappropriate senses, then it is used to modify the initial LDA topic model according to the generalized Polya urn model described in BIBREF9 . The generalized Polya urn model boosts probabilities of related words in word-topic distributions.\nGao and Wen BIBREF10 presented Semantic Similarity-Enhanced Topic Model that accounts for corpus-specific word co-occurrence and word semantic similarity calculated on WordNet paths between corresponding synsets using the generalized Polya urn model. They apply their topic model for categorizing short texts.\nAll above-mentioned approaches on adding knowledge to topic models are limited to single words. Approaches using ngrams in topic models can be subdivided into two groups. The first group of methods tries to create a unified probabilistic model accounting unigrams and phrases. Bigram-based approaches include the Bigram Topic Model BIBREF11 and LDA Collocation Model BIBREF12 . In BIBREF13 the Topical N-Gram Model was proposed to allow the generation of ngrams based on the context. However, all these models are enough complex and hard to compute on real datasets.\nThe second group of methods is based on preliminary extraction of ngrams and their further use in topics generation. Initial studies of this approach used only bigrams BIBREF14 , BIBREF15 . Nokel and Loukachevitch BIBREF16 proposed the LDA-SIM algorithm, which integrates top-ranked ngrams and terms of information-retrieval thesauri into topic models (thesaurus relations were not utilized). They create similarity sets of expressions having the same word components and sum up frequencies of similarity set members if they co-occur in the same text.\nIn this paper we describe the approach to integrate whole manual thesauri into topic models together with multiword expressions.\nAndrzejewski et al. [6] incorporated knowledge by Must-Link and Cannot-Link primitives represented by a Dirichlet Forest prior. These primitives were then used in [7], where similar words are encouraged to have similar topic distributions.",

        "answer": "The backward propagation of the perturbations from the continuous embedding space to the discrete token space is the major bottleneck.",
        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nA major bottleneck in applying gradient based (Goodfellow et al., 2015) or generator model (Zhao et al., 2018) based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.",

        "question": "What approach does the paper propose?",
        "answer": "A new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nThe main contributions of this paper are as follows: We propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.",

        "question": "What does the team focus on in this study?",
        "answer": "In this paper, they focus on question generation from reading comprehension materials like SQuAD.",
        "evidence": "Question Generation (QG) is the task of automatically creating questions from a range of inputs, such as natural language text BIBREF0, knowledge base BIBREF1 and image BIBREF2. QG is an increasingly important area in NLP with various application scenarios such as intelligence tutor systems, open-domain chatbots and question answering dataset construction. In this paper, we focus on question generation from reading comprehension materials like SQuAD BIBREF3. As shown in Figure FIGREF1, given a sentence in the reading comprehension paragraph and the text fragment (i.e., the answer) that we want to ask about, we aim to generate a question that is asked about the specified answer.\nQuestion generation for reading comprehension is firstly formalized as a declarative-to-interrogative sentence transformation problem with predefined rules or templates BIBREF4, BIBREF0. With the rise of neural models, Du2017LearningTA propose to model this task under the sequence-to-sequence (Seq2Seq) learning framework BIBREF5 with attention mechanism BIBREF6. However, question generation is a one-to-many sequence generation problem, i.e., several aspects can be asked given a sentence. Zhou2017NeuralQG propose the answer-aware question generation setting which assumes the answer, a contiguous span inside the input sentence, is already known before question generation. To capture answer-relevant words in the sentence, they adopt a BIO tagging scheme to incorporate the answer position embedding in Seq2Seq learning. Furthermore, Sun2018AnswerfocusedAP propose that tokens close to the answer fragments are more likely to be answer-relevant. Therefore, they explicitly encode the relative distance between sentence words and the answer via position embedding and position-aware attention.\nAlthough existing proximity-based answer-aware approaches achieve reasonable performance, we argue that such intuition may not apply to all cases especially for sentences with complex structure. For example, Figure FIGREF1 shows such an example where those approaches fail. This sentence contains a few facts and due to the parenthesis (i.e. “the area's coldest month”), some facts intertwine: “The daily mean temperature in January is 0.3$^\\circ $C” and “January is the area's coldest month”. From the question generated by a proximity-based answer-aware baseline, we find that it wrongly uses the word “coldest” but misses the correct word “mean” because “coldest” has a shorter distance to the answer “0.3$^\\circ $C”.\nIn summary, their intuition that “the neighboring words of the answer are more likely to be answer-relevant and have a higher chance to be used in the question” is not reliable. To quantitatively show this drawback of these models, we implement the approach proposed by Sun2018AnswerfocusedAP and analyze its performance under different relative distances between the answer and other non-stop sentence words that also appear in the ground truth question. The results are shown in Table TABREF2. We find that the performance drops at most 36% when the relative distance increases from “$0\\sim 10$” to “$>10$”. In other words, when the useful context is located far away from the answer, current proximity-based answer-aware approaches will become less effective, since they overly emphasize neighboring words of the answer.\nTo address this issue, we extract the structured answer-relevant relations from sentences and propose a method to jointly model such structured relation and the unstructured sentence for question generation. The structured answer-relevant relation is likely to be to the point context and thus can help keep the generated question to the point. For example, Figure FIGREF1 shows our framework can extract the right answer-relevant relation (“The daily mean temperature in January”, “is”, “32.6$^\\circ $F (0.3$^\\circ $C)”) among multiple facts. With the help of such structured information, our model is less likely to be confused by sentences with a complex structure. Specifically, we firstly extract multiple relations with an off-the-shelf Open Information Extraction (OpenIE) toolbox BIBREF7, then we select the relation that is most relevant to the answer with carefully designed heuristic rules.\nNevertheless, it is challenging to train a model to effectively utilize both the unstructured sentence and the structured answer-relevant relation because both of them could be noisy: the unstructured sentence may contain multiple facts which are irrelevant to the target question, while the limitation of the OpenIE tool may produce less accurate extracted relations. To explore their advantages simultaneously and avoid the drawbacks, we design a gated attention mechanism and a dual copy mechanism based on the encoder-decoder framework, where the former learns to control the information flow between the unstructured and structured inputs, while the latter learns to copy words from two sources to maintain the informativeness and faithfulness of generated questions.\nIn the evaluations on the SQuAD dataset, our system achieves significant and consistent improvement as compared to all baseline methods. In particular, we demonstrate that the improvement is more significant with a larger relative distance between the answer and other non-stop sentence words that also appear in the ground truth question. Furthermore, our model is capable of generating diverse questions for a single sentence-answer pair where the sentence conveys multiple relations of its answer fragment.\nIn this paper, we focus on question generation from reading comprehension materials like SQuAD (Rajpurkar et al., 2016).",

        "evidence": "Negotiations, either between individuals or entities, are ubiquitous in everyday human interactions ranging from sales to legal proceedings. Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nAlthough there have been attempts to gain insights into negotiations, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section  2).",

        "evidence": "In mathematics, a simple Lie group is a connected non-abelian Lie group G which does not have nontrivial connected normal subgroups. The list of simple Lie groups can be used to read off the list of simple Lie algebras and Riemannian symmetric spaces.\n\nTogether with the commutative Lie group of the real numbers, \n\\mathbb {R} , and that of the unit-magnitude complex numbers, U(1) (the unit circle), simple Lie groups give the atomic \"blocks\" that make up all (finite-dimensional) connected Lie groups via the operation of group extension. Many commonly encountered Lie groups are either simple or 'close' to being simple: for example, the so-called \"special linear group\" SL(n) of n by n matrices with determinant equal to 1 is simple for all n > 1.\n\nThe first classification of simple Lie groups was by Wilhelm Killing, and this work was later perfected by Élie Cartan. The final classification is often referred to as Killing-Cartan classification.",
        "answer": "Unfortunately, there is no universally accepted definition of a simple Lie group. In particular, it is not always defined as a Lie group that is simple as an abstract group. Authors differ on whether a simple Lie group has to be connected, or on whether it is allowed to have a non-trivial center, or on whether \n�\n\\mathbb {R}  is a simple Lie group.\n\nThe most common definition is that a Lie group is simple if it is connected, non-abelian, and every closed connected normal subgroup is either the identity or the whole group. In particular, simple groups are allowed to have a non-trivial center, but \n�\n\\mathbb {R}  is not simple.\n\nIn this article the connected simple Lie groups with trivial center are listed. Once these are known, the ones with non-trivial center are easy to list as follows. Any simple Lie group with trivial center has a universal cover, whose center is the fundamental group of the simple Lie group. The corresponding simple Lie groups with non-trivial center can be obtained as quotients of this universal cover by a subgroup of the center.\n\nAlternatives\nAn equivalent definition of a simple Lie group follows from the Lie correspondence: A connected Lie group is simple if its Lie algebra is simple. An important technical point is that a simple Lie group may contain discrete normal subgroups. For this reason, the definition of a simple Lie group is not equivalent to the definition of a Lie group that is simple as an abstract group.\n\nSimple Lie groups include many classical Lie groups, which provide a group-theoretic underpinning for spherical geometry, projective geometry and related geometries in the sense of Felix Klein's Erlangen program. It emerged in the course of classification of simple Lie groups that there exist also several exceptional possibilities not corresponding to any familiar geometry. These exceptional groups account for many special examples and configurations in other branches of mathematics, as well as contemporary theoretical physics.\n\nAs a counterexample, the general linear group is neither simple, nor semisimple. This is because multiples of the identity form a nontrivial normal subgroup, thus evading the definition. Equivalently, the corresponding Lie algebra has a degenerate Killing form, because multiples of the identity map to the zero element of the algebra. Thus, the corresponding Lie algebra is also neither simple nor semisimple. Another counter-example are the special orthogonal groups in even dimension. These have the matrix \n−\n�\n-I in the center, and this element is path-connected to the identity element, and so these groups evade the definition. Both of these are reductive groups.",

We use 45 tag clusters, the number of POS tags that appear in WSJ corpus. We train the discrete HMM and the Gaussian HMM BIBREF9 as baselines. For the Gaussian HMM, mean vectors of Gaussian emissions are initialized with the empirical mean of all word vectors with an additive noise. We assume diagonal covariance matrix for INLINEFORM0 and initialize it with the empirical variance of the word vectors. Following BIBREF9 , the covariance matrix is fixed during training. The multinomial probabilities are initialized as INLINEFORM1 , where INLINEFORM2 . For our approach, we initialize the syntax model and Gaussian parameters with the pre-trained Gaussian HMM. The weights of layers in the rectified network are initialized from a uniform distribution with mean zero and a standard deviation of INLINEFORM3 , where INLINEFORM4 is the input dimension. We evaluate the performance of POS tagging with both Many-to-One (M-1) accuracy BIBREF23 and V-Measure (VM) BIBREF24 . Given a model we found that the tagging performance is well-correlated with the training data likelihood, thus we use training data likelihood as a unsupervised criterion to select the trained model over 10 random restarts after training 50 epochs. We repeat this process 5 times and report the mean and standard deviation of performance.\nWe compare our approach with basic HMM, Gaussian HMM, and several state-of-the-art systems, including sophisticated HMM variants and clustering techniques with hand-engineered features. The results are presented in Table TABREF32 . Through the introduced latent embeddings and additional neural projection, our approach improves over the Gaussian HMM by 5.4 points in M-1 and 5.6 points in VM. Neural HMM (NHMM) BIBREF10 is a baseline that also learns word representation jointly. Both their basic model and extended Conv version does not outperform the Gaussian HMM. Their best model incorporates another LSTM to model long distance dependency and breaks the Markov assumption, yet our approach still achieves substantial improvement over it without considering more context information. Moreover, our method outperforms the best published result that benefits from hand-engineered features BIBREF27 by 2.0 points on VM.\nWe found that most tagging errors happen in noun subcategories. Therefore, we do the one-to-one mapping between gold POS tags and induced clusters and plot the normalized confusion matrix of noun subcategories in Figure FIGREF35 . The Gaussian HMM fails to identify “NN” and “NNS” correctly for most cases, and it often recognizes “NNPS” as “NNP”.

It further shows that for downstream tasks, like NER and SA, there's no silver bullet! However, some combinations show strong performance across tasks. Performance of embeddings is task-specific and high analogy scores do not necessarily correlate positively with performance on downstream tasks. This point on correlation is somewhat similar to results by BIBREF24 and BIBREF14. It was discovered that increasing dimension size depreciates performance after a point. If strong considerations of saving time, energy and the environment are made, then reasonably smaller corpora may suffice or even be better in some cases. The on-going drive by many researchers to use ever-growing data to train deep neural networks can benefit from the findings of this work. Indeed, hyper-parameter choices are very important in neural network systems (BIBREF19).\nFuture work that may be investigated are performance of other architectures of word or sub-word embeddings, the performance and comparison of embeddings applied to languages other than English and how embeddings perform in other downstream tasks. In addition, since the actual reason for the changes in best model as corpus size increases is not clear, this will also be suitable for further research.\nThe work on this project is partially funded by Vinnova under the project number 2019-02996 \"Språkmodeller för svenska myndigheter\"\nThe on-going drive by many researchers to use ever-growing data to train deep neural networks can benefit from the findings of this work.

        "evidence": "With the rapid growth of the internet, huge amounts of text data are generated in social networks, online shopping and news websites, etc. These data create demand for powerful and efficient text analysis techniques. Probabilistic topic models such as Latent Dirichlet Allocation (LDA) BIBREF0 are popular approaches for this task, by discovering latent topics from text collections. Many conventional topic models discover topics purely based on the word-occurrences, ignoring the meta information (a.k.a., side information) associated with the content. In contrast, when we humans read text it is natural to leverage meta information to improve our comprehension, which includes categories, authors, timestamps, the semantic meanings of the words, etc. Therefore, topic models capable of using meta information should yield improved modelling accuracy and topic quality.\nIn practice, various kinds of meta information are available at the document level and the word level in many corpora. At the document level, labels of documents can be used to guide topic learning so that more meaningful topics can be discovered. Moreover, it is highly likely that documents with common labels discuss similar topics, which could further result in similar topic distributions. For example, if we use authors as labels for scientific papers, the topics of the papers published by the same researcher can be closely related.\nAt the word level, different semantic/syntactic features are also accessible. For example, there are features regarding word relationships, such as synonyms obtained from WordNet BIBREF1 , word co-occurrence patterns obtained from a large corpus, and linked concepts from knowledge graphs. It is preferable that words having similar meaning but different morphological forms, like “dog” and “puppy”, are assigned to the same topic, even if they barely co-occur in the modelled corpus. Recently, word embeddings generated by GloVe BIBREF2 and word2vec BIBREF3 , have attracted a lot of attention in natural language processing and related fields. It has been shown that the word embeddings can capture both the semantic and syntactic features of words so that similar words are close to each other in the embedding space. It seems reasonable to expect that these word embedding will improve topic modelling BIBREF4 , BIBREF5 .\nConventional topic models can suffer from a large performance degradation over short texts (e.g., tweets and news headlines) because of insufficient word co-occurrence information. In such cases, meta information of documents and words can play an important role in analysing short texts by compensating the lost information in word co-occurrences. At the document level, for example, tweets are usually associated with hashtags, users, locations, and timestamps, which can be used to alleviate the data sparsity problem. At the word level, word semantic similarity and embeddings obtained or trained on large external corpus (e.g., Google News or Wikipedia) have been proven useful in learning meaningful topics from short texts BIBREF6 , BIBREF7 .\nThe benefit of using document and word meta information separately is shown in several models such as BIBREF8 , BIBREF9 , BIBREF5 . However, in existing models this is usually not efficient enough due to non-conjugacy and/or complex model structures. Moreover, only one kind of meta information (either at document level or at word level) is used in most existing models. In this paper, we propose MetaLDA, a topic model that can effectively and efficiently leverage arbitrary document and word meta information encoded in binary form. Specifically, the labels of a document in MetaLDA are incorporated in the prior of the per-document topic distributions. If two documents have similar labels, their topic distributions should be generated with similar Dirichlet priors. Analogously, at the word level, the features of a word are incorporated in the prior of the per-topic word distributions, which encourages words with similar features to have similar weights across topics. Therefore, both document and word meta information, if and when they are available, can be flexibly and simultaneously incorporated using MetaLDA. MetaLDA has the following key properties:\nWe conduct extensive experiments with several real datasets including regular and short texts in various domains. The experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.\nMetaLDA has the following key properties: We conduct extensive experiments with several real datasets including regular and short texts in various domains.",

        "evidence": "",
        "answer": "Protein purification is a series of processes intended to isolate one or a few proteins from a complex mixture, usually cells, tissues or whole organisms. Protein purification is vital for the specification of the function, structure and interactions of the protein of interest. The purification process may separate the protein and non-protein parts of the mixture, and finally separate the desired protein from all other proteins. Ideally, to study a protein of interest, it must be separated from other components of the cell so that contaminants won't interfere in the examination of the protein of interest's structure and function. Separation of one protein from all others is typically the most laborious aspect of protein purification. Separation steps usually exploit differences in protein size, physico-chemical properties, binding affinity and biological activity. The pure result may be termed protein isolate.",

        "answer": "Adaptive classification thresholds.",
        "evidence": "Named entity typing is the task of detecting the type (e.g., person, location, or organization) of a named entity in natural language text. Entity type information has shown to be useful in natural language tasks such as question answering BIBREF0 , knowledge-base population BIBREF1 , BIBREF2 , and co-reference resolution BIBREF3 . Motivated by its application to downstream tasks, recent work on entity typing has moved beyond standard coarse types towards finer-grained semantic types with richer ontologies BIBREF0 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . Rather than assuming an entity can be uniquely categorized into a single type, the task has been approached as a multi-label classification problem: e.g., in “... became a top seller ... Monopoly is played in 114 countries. ...” (fig:arch), “Monopoly” is considered both a game as well as a product.\nThe state-of-the-art approach BIBREF8 for fine-grained entity typing employs an attentive neural architecture to learn representations of the entity mention as well as its context. These representations are then combined with hand-crafted features (e.g., lexical and syntactic features), and fed into a linear classifier with a fixed threshold. While this approach outperforms previous approaches which only use sparse binary features BIBREF4 , BIBREF6 or distributed representations BIBREF9 , it has a few drawbacks: (1) the representations of left and right contexts are learnt independently, ignoring their mutual connection; (2) the attention on context is computed solely upon the context, considering no alignment to the entity; (3) document-level contexts which could be useful in classification are not exploited; and (4) hand-crafted features heavily rely on system or human annotations.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts. Further, we find that adaptive classification thresholds leads to further improvements. Experiments demonstrate that our approach, without any reliance on hand-crafted features, outperforms prior work on three benchmark datasets.\nFurther, we find that adaptive classification thresholds leads to further improvements.",

It has been found that running up to 80% of your  weekly miles at a very comfortable slow pace was optimal for the fastest improvement.  A slow pace can be measured by running at or below 70% of your maximum heart rate (MHR=220 beats per minute minus your age).  For those who don't have a heart rate monitor, another way to measure that you are in this zone is by being able to have a conversation without being out of breath. This “run slow to get faster\" methodology has been embraced by the elite running community and some believe has contributed to the multiple recent world records for both men and women in the middle and long distances.

Data structures in Spark are based on resilient distributed datasets (RDD), a read only multi-set of data which can be distributed over a cluster of machines and is fault tolerant. Spark applications run as separate processes on different clusters and are coordinated by the Spark object also referred to as the SparkContext. This element is the main driver of the program which connects with the cluster manager and helps acquire executors on different nodes to allocate resource across applications. Spark is highly scalable, being 100x faster than Hadoop on large datasets, and provides out of the box libraries for both streaming and machine learning.\nSpark RDD has the innate capability to recover itself because it stores all execution steps in a lineage graph. In case of any faults in the system, Spark redoes all the previous executions from the built DAG and recovers itself to the previous steady state from any fault such as memory overload. Spark RDDs lie in the core of KryptoOracle and therefore make it easier for it to recover from faults. Moreover, faults like memory overload or system crashes may require for the whole system to hard reboot.

We report the results on the Gigaword and the CNN dataset in Table 2 and Table 3 , respectively. In Gigaword dataset where the texts are short, our best model achieves a comparable performance with the current state-of-the-art. In CNN dataset where the texts are longer, our best model outperforms all the previous models. We emphasize that E2T module is easily attachable to better models, and we expect E2T to improve their performance as well. Overall, E2T achieves a significant improvement over the baseline model base, with at least 2 ROUGE-1 points increase in the Gigaword dataset and 6 ROUGE-1 points increase in the CNN dataset. In fact, all variants of E2T gain improvements over the baseline, implying that leveraging on linked entities improves the performance of the summarizer. Among the model variants, the CNN-based encoder with selective disambiguation and firm attention performs the best.\nAutomatic evaluation on the Gigaword dataset shows that the CNN and RNN variants of base+E2T have similar performance. To break the tie between both models, we also conduct human evaluation on the Gigaword dataset. We instruct two annotators to read the input sentence and rank the competing summaries from first to last according to their relevance and fluency: (a) the original summary gold, and from models (b) base, (c) base+E2Tcnn, and (d) base+E2Trnn. We then compute (i) the proportion of every ranking of each model and (ii) the mean rank of each model. The results are reported in Table 4 . The model with the best mean rank is base+E2Tcnn, followed by gold, then by base+E2Trnn and base, respectively. We also perform ANOVA and post-hoc Tukey tests to show that the CNN variant is significantly ( $p<0.01$ ) better than the RNN variant and the base model. The RNN variant does not perform as well as the CNN variant, contrary to the automatic ROUGE evaluation above. Interestingly, the CNN variant produces better (but with no significant difference) summaries than the gold summaries. We posit that this is due to the fact that the article title does not correspond to the summary of the first sentence.\nWe report the ROUGE F1 scores for both datasets of all the competing models using ROUGE F1 scores (Lin, 2004).",

        "evidence": "Informal fallacies – arguments that are logically unsound for lack of well-grounded premises.\n\nArgument to moderation (false compromise, middle ground, fallacy of the mean, argumentum ad temperantiam) – assuming that a compromise between two positions is always correct.\nContinuum fallacy (fallacy of the beard, line-drawing fallacy, sorites fallacy, fallacy of the heap, bald man fallacy, decision-point fallacy) – improperly rejecting a claim for being imprecise.\nCorrelative-based fallacies\nSuppressed correlative – a correlative is redefined so that one alternative is made impossible (e.g., \"I'm not fat because I'm thinner than John.\").\nDefinist fallacy – defining a term used in an argument in a biased manner (e.g., using \"loaded terms\"). The person making the argument expects that the listener will accept the provided definition, making the argument difficult to refute.\nDivine fallacy (argument from incredulity) – arguing that, because something is so incredible or amazing, it must be the result of superior, divine, alien or paranormal agency.\nDouble counting – counting events or occurrences more than once in probabilistic reasoning, which leads to the sum of the probabilities of all cases exceeding unity.\nEquivocation – using a term with more than one meaning in a statement without specifying which meaning is intended.\nAmbiguous middle term – using a middle term with multiple meanings.\nDefinitional retreat – changing the meaning of a word when an objection is raised. Often paired with moving the goalposts (see below), as when an argument is challenged using a common definition of a term in the argument, and the arguer presents a different definition of the term and thereby demands different evidence to debunk the argument.\nMotte-and-bailey fallacy – conflating two positions with similar properties, one modest and easy to defend (the \"motte\") and one more controversial (the \"bailey\"). The arguer first states the controversial position, but when challenged, states that they are advancing the modest position.\nFallacy of accent – changing the meaning of a statement by not specifying on which word emphasis falls.\nPersuasive definition – purporting to use the \"true\" or \"commonly accepted\" meaning of a term while, in reality, using an uncommon or altered definition.\n(cf. the if-by-whiskey fallacy)\nEcological fallacy – inferring about the nature of an entity based solely upon aggregate statistics collected for the group to which that entity belongs.\nEtymological fallacy – assuming that the original or historical meaning of a word or phrase is necessarily similar to its actual present-day usage.\nFallacy of composition – assuming that something true of part of a whole must also be true of the whole.\nFallacy of division – assuming that something true of a composite thing must also be true of all or some of its parts.\nFalse attribution – appealing to an irrelevant, unqualified, unidentified, biased or fabricated source in support of an argument.\nFallacy of quoting out of context (contextotomy, contextomy; quotation mining) – selective excerpting of words from their original context to distort the intended meaning.\nFalse authority (single authority) – using an expert of dubious credentials or using only one opinion to promote a product or idea. Related to the appeal to authority.\nFalse dilemma (false dichotomy, fallacy of bifurcation, black-or-white fallacy) – two alternative statements are given as the only possible options when, in reality, there are more.\nFalse equivalence – describing two or more statements as virtually equal when they are not.\nFeedback fallacy – believing in the objectivity of an evaluation to be used as the basis for improvement without verifying that the source of the evaluation is a disinterested party.\nHistorian's fallacy – assuming that decision-makers of the past had identical information as those subsequently analyzing the decision. This should not to be confused with presentism, in which present-day ideas and perspectives are anachronistically projected into the past.\nHistorical fallacy – believing that certain results occurred only because a specific process was performed, though said process may actually be unrelated to the results.\nBaconian fallacy – supposing that historians can obtain the \"whole truth\" via induction from individual pieces of historical evidence. The \"whole truth\" is defined as learning \"something about everything\", \"everything about something\", or \"everything about everything\". In reality, a historian \"can only hope to know something about something\".\nHomunculus fallacy – using a \"middle-man\" for explanation; this sometimes leads to regressive middle-men. It explains a concept in terms of the concept itself without explaining its real nature (e.g.: explaining thought as something produced by a little thinker – a homunculus – inside the head simply identifies an intermediary actor and does not explain the product or process of thinking).\nInflation of conflict – arguing that, if experts in a field of knowledge disagree on a certain point within that field, no conclusion can be reached or that the legitimacy of that field of knowledge is questionable.\nIf-by-whiskey – an argument that supports both sides of an issue by using terms that are emotionally sensitive and ambiguous.\nIncomplete comparison – insufficient information is provided to make a complete comparison.\nIntentionality fallacy – the insistence that the ultimate meaning of an expression must be consistent with the intention of the person from whom the communication originated (e.g. a work of fiction that is widely received as a blatant allegory must necessarily not be regarded as such if the author intended it not to be so).\nKafkatrapping – a sophistical rhetorical device in which any denial by an accused person serves as evidence of guilt.\nKettle logic – using multiple, jointly inconsistent arguments to defend a position.\nLudic fallacy – failing to take into account that non-regulated random occurrences unknown unknowns can affect the probability of an event taking place.\nLump of labour fallacy – the misconception that there is a fixed amount of work to be done within an economy, which can be distributed to create more or fewer jobs.\nMcNamara fallacy (quantitative fallacy) – making an argument using only quantitative observations (measurements, statistical or numerical values) and discounting subjective information that focuses on quality (traits, features, or relationships).\nMind projection fallacy – assuming that a statement about an object describes an inherent property of the object, rather than a personal perception.\nMoralistic fallacy – inferring factual conclusions from evaluative premises in violation of fact–value distinction (e.g.: inferring is from ought). Moralistic fallacy is the inverse of naturalistic fallacy.\nMoving the goalposts (raising the bar) – argument in which evidence presented in response to a specific claim is dismissed and some other (often greater) evidence is demanded.\nNirvana fallacy (perfect-solution fallacy) – solutions to problems are rejected because they are not perfect.\nPackage deal – treating essentially dissimilar concepts as though they were essentially similar.\nProof by assertion – a proposition is repeatedly restated regardless of contradiction; sometimes confused with argument from repetition (argumentum ad infinitum, argumentum ad nauseam).\nProsecutor's fallacy – a low probability of false matches does not mean a low probability of some false match being found.\nProving too much – an argument that results in an overly generalized conclusion (e.g.: arguing that drinking alcohol is bad because in some instances it has led to spousal or child abuse).\nPsychologist's fallacy – an observer presupposes the objectivity of their own perspective when analyzing a behavioral event.\nReferential fallacy – assuming that all words refer to existing things and that the meaning of words reside within the things they refer to, as opposed to words possibly referring to no real object (e.g.: Pegasus) or that the meaning comes from how they are used (e.g.: \"nobody\" was in the room).\nReification (concretism, hypostatization, or the fallacy of misplaced concreteness) – treating an abstract belief or hypothetical construct as if it were a concrete, real event or physical entity (e.g.: saying that evolution selects which traits are passed on to future generations; evolution is not a conscious entity with agency).\nRetrospective determinism – believing that, because an event has occurred under some circumstance, the circumstance must have made the event inevitable (e.g.: because someone won the lottery while wearing their lucky socks, wearing those socks made winning the lottery inevitable).\nSlippery slope (thin edge of the wedge, camel's nose) – asserting that a proposed, relatively small, first action will inevitably lead to a chain of related events resulting in a significant and negative event and, therefore, should not be permitted.\nSpecial pleading – the arguer attempts to cite something as an exemption to a generally accepted rule or principle without justifying the exemption (e.g.: an orphaned defendant who murdered their parents asking for leniency).",

        "question": "Is event data useful in forecasting models of conflict?",
        "answer": "Yes.",
        "evidence": "Political event data has existed in various forms since the 1970s. Two of the most common political event datasets were the World Event Interaction Survey (WEIS) and the Conflict and Peace Data Bank (COPDAB) BIBREF0 , BIBREF1 . These two datasets were eventually replaced by the projects created by Philip Schrodt and various collaborators. In general, these projects were marked by the use of the Conflict and Mediation Event Observations (CAMEO) coding ontology and automated, machine-coding rather than human coding BIBREF2 , BIBREF3 . The CAMEO ontology is made up of 20 “top-level” categories that encompass actions such as “Make Statement” or “Protest”, and contains over 200 total event classifications. This ontology has served as the basis for most of the modern event datasets such as the Integrated Crisis Early Warning System (ICEWS) BIBREF4 , the Global Database of Events, Language, and Tone (GDELT), and the Phoenix dataset presented in this paper.\nThis type of data can prove highly useful for many types of studies. Since this type of data is inherently atomic, each observation is a record of a single event between a source and a target, it provides a disaggregated view of political events. This means that the data can be used to examine interactions below the usual monthly or yearly levels of aggregation. This approach can be used in a manner consistent with traditional hypothesis testing that is the norm in political science BIBREF5 , BIBREF6 , BIBREF7 . Additionally, event data has proven useful in forecasting models of conflict since the finer time resolution allows analysts to gain better leverage over the prediction problem than is possible when using more highly aggregated data BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . Finally, the advent of daily-updated event data has led to many novel uses such as watchboarding or dashboarding. The goal in these situations is to provide an easy to understand interface that analysts can use to quickly monitor ongoing or emerging situations around the world. These applications provide a new frontier for event data that has not been considered much until this point.\nThe status quo of TABARI-generated, CAMEO-coded event data, which was established in the early 2000s, has remained with little change. BIBREF12 outlined many potential advances in the generation of political event data. These advances are things such as realtime processing of news stories, the incorporation of open-source natural language processing (NLP) software, and enhancements in the automated coding structure. Two publicly-available datasets, GDELT and ICEWS, have each attempted to implement some, or all, of these changes in their respective data-generating pipelines. In terms of goals, the ICEWS project seems closest to sharing the vision of the Phoenix dataset. A more in-depth comparison of Phoenix and ICEWS is presented in a later section. In short, the goal of the project presented in this chapter is to implement most of the improvements suggested in BIBREF12 .\nAdditionally, event data has proven useful in forecasting models of conflict since the finer time resolution allows analysts to gain better leverage over the prediction problem than is possible when using more highly aggregated data (Arva, Beieler, Fisher, Lara, Schrodt, Song, Sowell and Stehle 2013; Brandt, Freeman and Schrodt 2014; Brandt, Freeman, min Lin and Schrodt 2013; Brandt, Freeman and Schrodt 2011).",

        "question": "How many mechanisms do the authors present for adaptation?",
        "answer": "Two.",
        "evidence": "Speech-enabled natural-language question-answering interfaces to enterprise application systems, such as Incident-logging systems, Customer-support systems, Marketing-opportunities systems, Sales data systems etc., are designed to allow end-users to speak-out the problems/questions that they encounter and get automatic responses. The process of converting human spoken speech into text is performed by an Automatic Speech Recognition (ASR) engine. While functional examples of ASR with enterprise systems can be seen in day-to-day use, most of these work under constraints of a limited domain, and/or use of additional domain-specific cues to enhance the speech-to-text conversion process. Prior speech-and-natural language interfaces for such purposes have been rather restricted to either Interactive Voice Recognition (IVR) technology, or have focused on building a very specialized speech engine with domain specific terminology that recognizes key-words in that domain through an extensively customized language model, and trigger specific tasks in the enterprise application system. This makes the interface extremely specialized, rather cumbersome and non-adaptable for other domains. Further, every time a new enterprise application requires a speech and natural language interface, one has to redevelop the entire interface again.\nAn alternative to domain-specific speech recognition engines has been to re-purpose general-purpose speech recognition engines, such as Google Speech API, IBM Watson Speech to text API which can be used across domains with natural language question answering systems. Such general-purpose automatic speech engines (gp-ASR) are deep trained on very large general corpus using deep neural network (DNN) techniques. The deep learnt acoustic and language models enhance the performance of a ASR. However, this comes with its own limitations. For freely spoken natural language sentences, the typical recognition accuracy achievable even for state-of-the-art speech recognition systems have been observed to be about 60% to 90% in real-world environments BIBREF0 . The recognition is worse if we consider factors such as domain-specific words, environmental noise, variations in accent, poor ability to express on the part of the user, or inadequate speech and language resources from the domain to train such speech recognition systems. The subsequent natural language processing, such as that in a question answering system, of such erroneously and partially recognized text becomes rather problematic, as the domain terms may be inaccurately recognized or linguistic errors may creep into the sentence. It is, hence, important to improve the accuracy of the ASR output text.\nIn this paper, we focus on the issues of using a readily available gp-ASR and adapting its output for domain-specific natural language question answering BIBREF1 . We present two mechanisms for adaptation, namely\nWe present the results of these two adaptation and gauge the usefulness of each mechanism.

        "answer": "A subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nWe then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content.",

Putting this all together, we get\n\n```\ndef fib(n):\n\t# base case\n\tif n == 0:\n\t\treturn 0\n\tif n == 1:\n\t\treturn 1\n\n\t# recursive case\n\treturn fib(n - 1) + fib(n - 2)\n```\n\nThis will correctly calculate the nth Fibonacci number for nonnegative integer inputs n. However, recursively calculating Fibonacci numbers in this way takes exponential time in the value of n, so this code may be very slow for large inputs. It could be improved by memoizing previous results, or using a non-recursive approach. Simple iterative approaches can solve the problem more quickly, and closed-form expressions for the nth Fibonacci number exist and are even faster to evaluate.",

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation. Section SECREF3 describes our test suite. The context-aware models we use in our experiments are detailed in Section SECREF4 . We discuss our experiments in Section SECREF5 and the results in Section SECREF6 .\nThe test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis).",

        "evidence": "Electroencephalography (EEG) is a non invasive way of measuring electrical activity of human brain. In BIBREF0 we demonstrated deep learning based automatic speech recognition (ASR) using EEG signals for a limited English vocabulary of four words and five vowels. In this paper we extend our work for a much larger English vocabulary and we use state-of-art end-to-end continuous speech recognition models to perform recognition. In our prior work we predicted isolated words and vowels.\nASR systems forms the front end or back end in many cutting edge voice activated technologies like Amazon Alexa, Apple Siri, Windows Cortana, Samsung Bixby etc. Unfortunately these systems are trained to recognize text only from acoustic features. This limits technology accessibility to people with speaking disabilities and disorders. The research work presented in this paper tries to address this issue by investigating speech recognition using only EEG signals with no acoustic input and also by combining EEG features along with traditional acoustic features to perform recognition. We believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.\nASR performance is degraded in presence of noisy speech and in real life situations most of the speech is noisy. Inspired from the unique robustness to environmental artifacts exhibited by the human auditory cortex BIBREF1 , BIBREF2 we used very noisy speech data for this work and demonstrated lower word error rate (WER) for smaller corpus using EEG features, concatenation of EEG features and acoustic features.\nIn BIBREF3 authors decode imagined speech from EEG using synthetic EEG data and connectionist temporal classification (CTC) network but in our work we use real EEG data, use EEG data recorded along with acoustics. In BIBREF4 authors perform envisioned speech recognition using random forest classifier but in our case we use end to end state of art models and perform recognition for noisy speech. In BIBREF5 authors demonstrate speech recognition using electrocorticography (ECoG) signals, which are invasive in nature but in our work we use non invasive EEG signals.\nThis work is mainly motivated by the results explained in BIBREF0 , BIBREF6 , BIBREF7 , BIBREF3 . In BIBREF6 the authors used classification approach for identifying phonological categories in imagined and silent speech but in our work we used continuous speech recognition state of art models and our models were predicting words, characters at each time step. Similarly in BIBREF7 neural network based classification approach was used for predicting phonemes.\nMajor contribution of this paper is the demonstration of end to end continuous noisy speech recognition using only EEG features and this paper further validates the concepts introduced in BIBREF0 for a much larger English corpus.\nIn BIBREF0 we demonstrated deep learning based automatic speech recognition (ASR) using EEG signals for a limited English vocabulary of four words and five vowels.",

        "evidence": "If the translation of a pronoun requires context beyond the current sentence (see the example in Figure FIGREF1 ), a natural extension of sentence-level NMT models is to condition the model prediction on this necessary context. In the following, we describe a number of existing approaches to making models “aware” of additional context.\nThe simplest possible extension is to translate units larger than sentences. BIBREF5 concatenate each sentence with the sentence that precedes it, for the source side of the corpus or both sides. All of their models are standard sequence-to-sequence models built with recurrent neural networks (RNNs), since the method does not require any architectural change. BIBREF11 use the same concatenation technique with a Transformer architecture BIBREF2 , and experiment with wider context.\nA number of works do propose changes to the NMT architecture. A common technique is to extend a standard encoder-decoder model by additional encoders for the context sentence(s), with a modified attention mechanism BIBREF6 , BIBREF9 , BIBREF8 . One aspect that differs between these works is the architecture of the encoder and attention. While BIBREF6 , BIBREF9 extend an RNN encoder-decoder with a second encoder that the decoder attends to, BIBREF8 extend the Transformer architecture with an encoder that is attended to by the main encoder. BIBREF8 also introduce parameter sharing between the main encoder and the context encoder, but do not empirically demonstrate its importance.\nWhile the number of encoded sentences in the previous work is fixed, BIBREF7 , BIBREF10 explore the integration of variable-size context through a hierarchical architecture, where a first-level RNN reads in words to produce sentence vectors, which are then fed into a second-level RNN to produce a document summary.\nApart from differences in the architectures, related work varies in whether it considers source context, target context, or both (see Table TABREF9 for an overview of language arcs and context types). Some work considers only source context, but for pronoun translation, target-side context is intuitively important for disambiguation, especially if the antecedent itself is ambiguous. In our evaluation, we therefore emphasize models that take into account both source and target context.\nOur experiments are based on models from BIBREF9 , who have released their source code. We extend their models with parameter sharing, which was shown to be beneficial by BIBREF8 . Additionally, we consider a concatenative baseline, similar to BIBREF5 , and Transformer-based models BIBREF8 .\nThis section describes several context-aware NMT models that we use in our experiments. They fall into two major categories: models based on RNNs and models based on the Transformer architecture BIBREF2 . We experiment with additional context on the source side and target side.\nIn our evaluation, we therefore emphasize models that take into account both source and target context.",

        "answer": "A novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments.",
        "evidence": "Neural machine translation (NMT) emerged in the last few years as a very successful paradigm BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . While NMT is generally more fluent than previous statistical systems, adequacy is still a major concern BIBREF4 : common mistakes include dropping source words and repeating words in the generated translation.\nPrevious work has attempted to mitigate this problem in various ways. BIBREF5 incorporate coverage and length penalties during beam search—a simple yet limited solution, since it only affects the scores of translation hypotheses that are already in the beam. Other approaches involve architectural changes: providing coverage vectors to track the attention history BIBREF6 , BIBREF7 , using gating architectures and adaptive attention to control the amount of source context provided BIBREF8 , BIBREF9 , or adding a reconstruction loss BIBREF10 . BIBREF11 also use the notion of fertility implicitly in their proposed model. Their “fertility conditioned decoder” uses a coverage vector and an “extract gate” which are incorporated in the decoding recurrent unit, increasing the number of parameters.\nIn this paper, we propose a different solution that does not change the overall architecture, but only the attention transformation. Namely, we replace the traditional softmax by other recently proposed transformations that either promote attention sparsity BIBREF12 or upper bound the amount of attention a word can receive BIBREF13 . The bounds are determined by the fertility values of the source words. While these transformations have given encouraging results in various NLP problems, they have never been applied to NMT, to the best of our knowledge. Furthermore, we combine these two ideas and propose a novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments. While being in-between soft and hard alignments (Figure FIGREF20 ), the constrained sparsemax transformation is end-to-end differentiable, hence amenable for training with gradient backpropagation.\nTo sum up, our contributions are as follows:\nFurthermore, we combine these two ideas and propose a novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments.",

The goal of question generation (QG) is to generate a question that asks towards the answer with the given passage and the expected answer. In the following experiments, we extend the QG task to the cross-lingual setting. By only using English QG training data, our goal is to generate questions in English or Chinese with the given passage-answer pair in English or Chinese.\nWe use SQuAD 1.1 BIBREF30 as the English QG dataset. It is a popular English question answering dataset containing over 100,000 questions and their corresponding annotated passages. Following BIBREF31, we regard the original development set as the test set, and sample 5000 examples from the training data of two datasets as the development sets. For Chinese QG, we follow the default data splits of WebQA BIBREF32. We regard the provided annotated evidence sentences as the input passages instead of entire documents. To construct the input sequence, we view the whole input passage as a single sentence, and concatenate the passage and the answer into one sequence with a special token S between them. During decoding Chinese, we utilize a subset of vocabulary, which is obtained from the passage sentences of the WebQA dataset.\nWe first conduct experiments on the supervised English-English QG setting. We compare our model to the following baselines:\nCorefNqg BIBREF33 A sequence-to-sequence model with attention mechanism and a feature-rich encoder.\nMp-Gsn BIBREF31 A sequence-to-sequence model with gated self-attention and maxout pointer mechanism.\nXlm BIBREF5 The current state-of-the-art cross-lingual pre-training model. We initialize the Transformer-based sequence-to-sequence model with pre-trained XLM.\nWe evaluate models with BLEU-4 (BL-4), ROUGE (RG) and METEOR (MTR) metrics. As shown in Table TABREF16, our model outperforms the baselines, which demonstrates that our pre-trained model provides a good initialization for NLG.\nWe conduct experiments on the zero-shot Chinese-Chinese QG task to evaluate the cross-lingual transfer ability. In this task, models are trained with English QG data but evaluated with Chinese QG examples. We include the following models as our baselines:\nXlm Fine-tuning XLM with the English QG data.\nPipeline (Xlm) The pipeline of translating input Chinese sentences into English first, then performing En-En-QG with the XLM model, and finally translating back to the Chinese. We use the Transformer as the translator, which is also trained on the MultiUN dataset.\nPipeline (Xlm) with Google Translator Same to Pipeline (Xlm) but using Google Translator to translate the texts.\nWe evaluate models by both automatic evaluation metrics and human experts. The automatic metrics scores are computed by regarding each Chinese character as a token. For human evaluation, we consider three metrics for the generated questions: relatedness, fluency, and correctness, which are represented as integers ranged from 1 to 3. We randomly select 100 passage-answer pairs from the English QG test set, and use the models to generate questions. Then we present these examples to three experts to ask for the above scores. In Table TABREF17 and Table TABREF18, we present the results for the zero-shot Zh-Zh-QG. The results of monolingual supervised models are also reported in Table TABREF16 as reference. In the automatic evaluation, our model consistently performs better than baselines in both zero-shot and monolingual supervised setting. In the human evaluation, our model also obtains significant improvements in terms of relatedness and correctness.\nIn the zero-shot English-Chinese question generation experiments, we use Xlm and Pipeline (Xlm) as our baselines. Pipeline (Xlm) is a pipeline method that uses En-En-QG with Xlm to generate questions, and then translates the results to Chinese. Because there is no annotations for En-Zh-QG, we perform human evaluation studies for this setting.

        "evidence": "Conventional automatic speech recognition (ASR) systems typically consist of several independently learned components: an acoustic model to predict context-dependent sub-phoneme states (senones) from audio, a graph structure to map senones to phonemes, and a pronunciation model to map phonemes to words. Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other. We show competitive results on Wall Street Journal (WSJ), and 2000hr Fisher+Switchboard (F+S). Using only greedy decoding without a language model we achieve 3.86% WER on LibriSpeech test-clean.\nThis paper makes the following contributions:\nThe sub-block architecture of Jasper was designed to facilitate fast GPU inference.",

        "question": "What do you need when you see a blue flag during the race?",
        "evidence": "Race\nThe race begins with a warm-up lap, after which the cars assemble on the starting grid in the order they qualified. This lap is often referred to as the formation lap, as the cars lap in formation with no overtaking (although a driver who makes a mistake may regain lost ground). The warm-up lap allows drivers to check the condition of the track and their car, gives the tyres a chance to warm up to increase traction and grip, and also gives the pit crews time to clear themselves and their equipment from the grid for the race start.\n\n\nJacques Villeneuve qualifying at the 2005 United States Grand Prix in his Sauber C24\nOnce all the cars have formed on the grid, after the medical car positions itself behind the pack, a light system above the track indicates the start of the race: five red lights are illuminated at intervals of one second; they are all then extinguished simultaneously after an unspecified time (typically less than 3 seconds) to signal the start of the race. The start procedure may be abandoned if a driver stalls on the grid or on the track in an unsafe position, signalled by raising their arm. If this happens, the procedure restarts: a new formation lap begins with the offending car removed from the grid. The race may also be restarted in the event of a serious accident or dangerous conditions, with the original start voided. The race may be started from behind the Safety Car if race control feels a racing start would be excessively dangerous, such as extremely heavy rainfall. As of the 2019 season, there will always be a standing restart. If due to heavy rainfall a start behind the safety car is necessary, then after the track has dried sufficiently, drivers will form up for a standing start. There is no formation lap when races start behind the Safety Car.\n\nUnder normal circumstances, the winner of the race is the first driver to cross the finish line having completed a set number of laps. Race officials may end the race early (putting out a red flag) due to unsafe conditions such as extreme rainfall, and it must finish within two hours, although races are only likely to last this long in the case of extreme weather or if the safety car is deployed during the race. When a situation justifies pausing the race without terminating it, the red flag is deployed; since 2005, a ten-minute warning is given before the race is resumed behind the safety car, which leads the field for a lap before it returns to the pit lane (before then the race resumed in race order from the penultimate lap before the red flag was shown).\n\nIn the 1950s, race distances varied from 300 km (190 mi) to 600 km (370 mi). The maximum race length was reduced to 400 km (250 mi) in 1966 and 325 km (202 mi) in 1971. The race length was standardised to the current 305 km (190 mi) in 1989. However, street races like Monaco have shorter distances, to keep under the two-hour limit.\n\nDrivers may overtake one another for position over the course of the race. If a leader comes across a backmarker (slower car) who has completed fewer laps, the back marker is shown a blue flag telling them that they are obliged to allow the leader to overtake them. The slower car is said to be \"lapped\" and, once the leader finishes the race, is classified as finishing the race \"one lap down\". A driver can be lapped numerous times, by any car in front of them. A driver who fails to complete more than 90% of the race distance is shown as \"not classified\" in the results.\n\nThroughout the race, drivers may make pit stops to change tyres and repair damage (from 1994 to 2009 inclusive, they could also refuel). Different teams and drivers employ different pit stop strategies in order to maximise their car's potential. Three dry tyre compounds, with different durability and adhesion characteristics, are available to drivers. Over the course of a race, drivers must use two of the three available compounds. The different compounds have different levels of performance and choosing when to use which compound is a key tactical decision to make. Different tyres have different colours on their sidewalls; this allows spectators to understand the strategies.\n\nUnder wet conditions, drivers may switch to one of two specialised wet weather tyres with additional grooves (one \"intermediate\", for mild wet conditions, such as after recent rain, one \"full wet\", for racing in or immediately after rain). A driver must make at least one stop to use two tyre compounds; up to three stops are typically made, although further stops may be necessary to fix damage or if weather conditions change. If rain tyres are used, drivers are no longer obliged to use both types of dry tyres.",

        "evidence": "Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide.\n\nChess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. White moves first, followed by Black. Checkmating the opponent's king involves putting the king under immediate attack (in \"check\") whereby there is no way for it to escape. There are also several ways a game can end in a draw.\n\nOrganized chess arose in the 19th century. Chess competition today is governed internationally by FIDE (the International Chess Federation). The first universally recognized World Chess Champion, Wilhelm Steinitz, claimed his title in 1886; Magnus Carlsen is the current World Champion. A huge body of chess theory has developed since the game's inception. Aspects of art are found in chess composition, and chess in its turn influenced Western culture and art, and has connections with other fields such as mathematics, computer science, and psychology.\n\nOne of the goals of early computer scientists was to create a chess-playing machine. In 1997, Deep Blue became the first computer to beat the reigning World Champion in a match when it defeated Garry Kasparov. Today's chess engines are significantly stronger than the best human players and have deeply influenced the development of chess theory.",
        "answer": "Chess is a two player turn based abstract strategy board game with the goal of checkmating the opponents King. The game originated from a similar board game from India called Chatarunga, which was played during the 17th century.\n\nChess boards have 64 squares arranged into an 8x8 grid with alternating white and black squares. Each player controls 16 pieces: 1 king, 1 queen, 2 bishops, 2 rooks, 2 knights, and eight pawns. Each piece has a predefined mode of movement. Each player's pieces are uniformly colored; for example if player one has the white pieces, player one will start the match. \n\nCheckmating the opponents king requires the opponent to position their pieces into an attacking arrangement that prohibits the defending players king from moving. This is usually accomplished by closing in on their defending opponents king and systematically working towards positions where the king can no longer move without being taken. If the king is under attack (meaning the king is in a position where the opponents next move will take the king) the defensive player must either take the attacking piece with any piece on the board or move the king to a position where the king is no longer under attach, this configuration is called \"Check\" or being \"Checked\". Chess matches can also end in a draw.\n\nChess arose in popularity in the 19th century and is governed internationally by the FIDE (international chess federation). Magnus Carlsen is the current world champion (2023) and the game has a huge body of theory associated with playing the game. \n\nThe game has influenced western culture in the fields of art, mathematics, computer science and psychology. Computer scientists have used chess as a method for developing algorithms that can play chess. In 1997, Deep Blue became the first computer to beat a human opponent, beating the current world champion Garry Kasparov at that time.

Following your suggestion, we have modified the corresponding claim about Figure 1 in our updated manuscript.",
        "evidence": "Transformer, which was initially proposed for natural language processing (NLP) and is a type of deep neural networks (DNNs) mainly based on the self-attention mechanism, has achieved significant breakthroughs in NLP tasks. Thanks to its strong representation capabilities, many works have developed ways to apply Transformer to computer vision (CV) tasks, such as image classification, object detection, semantic segmentation , and video classification. Among them, Vision Transformer (ViT) stands out and demonstrates that a pure Transformer applied directly to sequences of image patches can perform very well on image classification tasks, e.g., achieving a comparable ImageNet top-1 accuracy as ResNet. Motivated by ViT's promising performance, a fast growing number of works follow it to explore pure Transformer architectures in order to push forward its accuracy-efficiency trade-off and deployment into real-world applications, achieving an even better performance than EfficientNetV1, a widely used efficient convolutional neural network (CNN).\nThe success of recent ViT works suggests that the model architecture is critical to ViT's achievable performance. Therefore, in this work we explore ViT architectures from a new perspective, aiming to analyze and understand ViT's architecture design space and real hardware-cost across different devices. Despite the recent excitement towards ViT models and the success of model scaling for CNNs, little effort has been made into exploring ViT's model scaling strategies or hardware-cost.\nDeiT-Scaled (Ours) PiT-Scaled (Ours) Our scaled ViT models achieve comparable or better accuracy-efficiency trade-off as compared to some recent dedicatedly designed ViT variants.\nNote that directly applying the scaling strategies for CNNs or Transformer on NLP tasks  will lead to sub-optimality, as discussed in Section 3.2. Furthermore, scaling strategies targeting one device/task might not be transferable to another device/task. Interestingly, we find that simply scaled ViT models can achieve comparable or even better accuracy-efficiency trade-off than dedicatedly designed ViT variants, as shown in Figure. Motivated by this, we further explore the transferability of our scaling strategies across different real hardware devices and (2) to different ViT variants and tasks. In particular, we make the following contributions:\n• We are the first to show that simply scaled vanilla ViT models can achieve comparable or even better accuracy-efficiency trade-off as compared to dedicatedly designed ViT variants, as illustrated in Figure. Specifically, as compared to DeiT-Tiny, our scaled model achieves a ↑ 1.9% higher ImageNet top-1 accuracy under the same FLOPs and a ↑ 3.7% better ImageNet top-1 accuracy under the same latency on an NVIDIA Edge GPU TX2. • We study the transferability of the scaled ViT models across different devices and show that the transferability effectiveness depends on the underlying devices and deployment tools. For example, scaling strategies targeting FLOPs or the throughput on V100 GPU (NVIDIA LLC.) can be transferred to the Pixel3 (Google LLC., a) device with little or even no performance loss, but those targeting the latency on TX2 (NVIDIA Inc., c) may not be transferred to other devices due to the obvious performance loss. Additionally, we provide ViT models' cost breakdown and rank correlation between their hardware-cost on different devices for better understanding it. • We show that our scaling strategies can also be effectively transferred to different ViT variants and recognition tasks to further boost the achieved accuracy-efficiency trade-off, e.g., achieving a ↑ 2.1% higher accuracy under a similar FLOPs when being transferred to the PiT model and ↑ 0.7% higher average precision under a similar inference throughput when being transferred to an object detection task.\nFigure 1: Our scaled ViT models achieve comparable or better accuracy-efficiency trade-off as compared to some recent dedicatedly designed ViT variants.",

        "evidence": "With India being a diverse linguistic region, there is an ever increasing usage of code-mixed Hindi-English language (along with various others) because bilingualism and even multilingualism are quite common. Consequently, we have also seen an increase in the usage of code-mixed language in online forums, advertisements etc. Code-mixed humour, especially puns have become increasingly popular because being able to use the same punning techniques but with two languages in play has opened up numerous avenues for new and interesting wordplays. With the increasing popularity and acceptance for the usage of code-mixed language, it has become important that computers are also able to process it and even decipher complex phenomena like humour. Traditional Word Sense Disambiguation (WSD) based methods cannot be used in target recovery of code-mixed puns, because they are no longer about multiple senses of a single word but about two words from two different languages. Code-switching comes with no markers, and the punning word may not even be a word in either of the languages being used. Sometimes words from the two languages can be combined to form a word which only a bilingual speaker would understand. Hence, this task on such data calls for a different set of strategies altogether. We approach this problem in two parts. First, we analyze the types of structures in code-mixed puns and classify them into two categories namely intra-sequential and intra-word. Second, we develop a four stage pipeline to achieve our goal - Language Identification, Pun Candidate Identification, Context Lookup and Phonetic Distance Minimization. We then test our approach on a small dataset and note that our method is successfully able to recover targets for a majority of the puns.\n First, we analyze the types of structures in code-mixed puns and classify them into two categories namely intra-sequential and intra-word.

        "question": "Which is more important in computational text analysis, reasoning why a certain prediction was made or the accuracy of the prediction itself?",
        "answer": "The accuracy of the prediction itself.",
        "evidence": "We typically start by identifying the questions we wish to explore. Can text analysis provide a new perspective on a “big question” that has been attracting interest for years? Or can we raise new questions that have only recently emerged, for example about social media? For social scientists working in computational analysis, the questions are often grounded in theory, asking: How can we explain what we observe? These questions are also influenced by the availability and accessibility of data sources. For example, the choice to work with data from a particular social media platform may be partly determined by the fact that it is freely available, and this will in turn shape the kinds of questions that can be asked. A key output of this phase are the concepts to measure, for example: influence; copying and reproduction; the creation of patterns of language use; hate speech. Computational analysis of text motivated by these questions is insight driven: we aim to describe a phenomenon or explain how it came about. For example, what can we learn about how and why hate speech is used or how this changes over time? Is hate speech one thing, or does it comprise multiple forms of expression? Is there a clear boundary between hate speech and other types of speech, and what features make it more or less ambiguous? In these cases, it is critical to communicate high-level patterns in terms that are recognizable.\nThis contrasts with much of the work in computational text analysis, which tends to focus on automating tasks that humans perform inefficiently. These tasks range from core linguistically motivated tasks that constitute the backbone of natural language processing, such as part-of-speech tagging and parsing, to filtering spam and detecting sentiment. Many tasks are motivated by applications, for example to automatically block online trolls. Success, then, is often measured by performance, and communicating why a certain prediction was made—for example, why a document was labeled as positive sentiment, or why a word was classified as a noun—is less important than the accuracy of the prediction itself. The approaches we use and what we mean by `success' are thus guided by our research questions.\nDomain experts and fellow researchers can provide feedback on questions and help with dynamically revising them. For example, they may say “we already think we know that”, “that's too naïve”, “that doesn't reflect social reality” (negative); “two major camps in the field would give different answers to that question” (neutral); “we tried to look at that back in the 1960s, but we didn't have the technology” (positive); and “that sounds like something that people who made that archive would love”, “that's a really fundamental question” (very positive).\nSometimes we also hope to connect to multiple disciplines. For example, while focusing on the humanistic concerns of an archive, we could also ask social questions such as “is this archive more about collaborative processes, culture-building or norm creation?” or “how well does this archive reflect the society in which it is embedded?\" BIBREF3 used quantitative methods to tell a story about Darwin's intellectual development—an essential biographical question for a key figure in the history of science. At the same time, their methods connected Darwin's development to the changing landscape of Victorian scientific culture, allowing them to contrast Darwin's “foraging” in the scientific literature of his time to the ways in which that literature was itself produced. Finally, their methods provided a case study, and validation of technical approaches, for cognitive scientists who are interested in how people explore and exploit sources of knowledge.\nQuestions about potential “dual use” may also arise. Returning to our introductory example, BIBREF0 started with a deceptively simple question: if an internet platform eliminates forums for hate speech, does this impact hate speech in other forums? The research was motivated by the belief that a rising tide of online hate speech was (and is) making the internet increasingly unfriendly for disempowered groups, including minorities, women, and LBGTQ individuals. Yet the possibility of dual use troubled the researchers from the onset. Could the methodology be adopted to target the speech of groups like Black Lives Matter? Could it be adopted by repressive governments to minimize online dissent? While these concerns remained, they concluded that hypothetical dual use scenarios did not outweigh the tangible contribution this research could offer towards making the online environment more equal and just.\nSuccess, then, is often measured by performance, and communicating why a certain prediction was made—for example, why a document was labeled as positive sentiment, or why a word was classified as a noun—is less important than the accuracy of the prediction itself.",

        "answer": "A recurrent neural network (RNN) model.",
        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nTo that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews.",

        "evidence": "A transformer is a deep learning model that adopts the mechanism of self-attention, differentially weighting the significance of each part of the input data. It is used primarily in the fields of natural language processing (NLP) and computer vision (CV).\n\nLike recurrent neural networks (RNNs), transformers are designed to process sequential input data, such as natural language, with applications towards tasks such as translation and text summarization. However, unlike RNNs, transformers process the entire input all at once. The attention mechanism provides context for any position in the input sequence. For example, if the input data is a natural language sentence, the transformer does not have to process one word at a time. This allows for more parallelization than RNNs and therefore reduces training times.\n\nTransformers were introduced in 2017 by a team at Google Brain and are increasingly becoming the model of choice for NLP problems, replacing RNN models such as long short-term memory (LSTM). The additional training parallelization allows training on larger datasets. This led to the development of pretrained systems such as BERT (Bidirectional Encoder Representations from Transformers) and GPT (Generative Pre-trained Transformer), which were trained with large language datasets, such as the Wikipedia Corpus and Common Crawl, and can be fine-tuned for specific tasks.",

        "answer": "By using a variant of the hinge-loss and introducing noise during training.",
        "evidence": "Given a piece of text and the span of an entity mention in this text, fine-grained entity typing (FET) is the task of assigning fine-grained type labels to the mention BIBREF0. The assigned labels should be context dependent BIBREF1. For example, in the sentence “Trump threatens to pull US out of World Trade Organization,” the mention “Trump” should be labeled as /person and /person/politician, although Donald Trump also had other occupations such as businessman, TV personality, etc.\nThis task is challenging because it usually uses a relatively large tag set, and some mentions may require the understanding of the context to be correctly labeled. Moreover, since manual annotation is very labor-intensive, existing approaches have to rely on distant supervision to train models BIBREF0, BIBREF2.\nThus, the use of extra information to help with the classification process becomes very important. In this paper, we improve FET with entity linking (EL). EL is helpful for a model to make typing decisions because if a mention is correctly linked to its target entity, we can directly obtain the type information about this entity in the knowledge base (KB). For example, in the sentence “There were some great discussions on a variety of issues facing Federal Way,” the mention “Federal Way” may be incorrectly labeled as a company by some FET models. Such a mistake can be avoided after linking it to the city Federal Way, Washington. For cases that require the understanding of the context, using entity linking results is also beneficial. In the aforementioned example where “Trump” is the mention, obtaining all the types of Donald Trump in the knowledge base (e.g., politician, businessman, TV personality, etc.) is still informative for inferring the correct type (i.e., politician) that fits the context, since they narrows the possible labels down.\nHowever, the information obtained through EL should not be fully trusted since it is not always accurate. Even when a mention is correctly linked to an entity, the type information of this entity in the KB may be incomplete or outdated. Thus, in this paper, we propose a deep neural fine-grained entity typing model that flexibly predicts labels based on the context, the mention string, and the type information from KB obtained with EL.\nUsing EL also introduces a new problem for the training process. Currently, a widely used approach to create FET training samples is to use the anchor links in Wikipedia BIBREF0, BIBREF3. Each anchor link is regarded as a mention, and is weakly labeled with all the types of its referred entity (the Wikipedia page the anchor link points to) in KB. Our approach, when links the mention correctly, also uses all the types of the referred entity in KB as extra information. This may cause the trained model to overfit the weakly labeled data. We design a variant of the hinge loss and introduce noise during training to address this problem.\nWe conduct experiments on two commonly used FET datasets. Experimental results show that introducing information obtained through entity linking and having a deep neural model both helps to improve FET performance. Our model achieves more than 5% absolute strict accuracy improvement over the state of the art on both datasets.\nOur contributions are summarized as follows:\nWe propose a deep neural fine-grained entity typing model that utilizes type information from KB obtained through entity linking.\nWe address the problem that our model may overfit the weakly labeled data by using a variant of the hinge-loss and introducing noise during training.\nWe demonstrate the effectiveness of our approach with experimental results on commonly used FET datasets.\nOur code is available at https://github.com/HKUST-KnowComp/IFETEL.\nWe address the problem that our model may overfit the weakly labeled data by using a variant of the hinge-loss and introducing noise during training.",

        "answer": "Neural network.",
        "evidence": "The need to access and digest large amounts of textual data has provided strong impetus to develop automatic summarization systems aiming to create shorter versions of one or more documents, whilst preserving their information content. Much effort in automatic summarization has been devoted to sentence extraction, where a summary is created by identifying and subsequently concatenating the most salient text units in a document.\nMost extractive methods to date identify sentences based on human-engineered features. These include surface features such as sentence position and length BIBREF0 , the words in the title, the presence of proper nouns, content features such as word frequency BIBREF1 , and event features such as action nouns BIBREF2 . Sentences are typically assigned a score indicating the strength of presence of these features. Several methods have been used in order to select the summary sentences ranging from binary classifiers BIBREF3 , to hidden Markov models BIBREF4 , graph-based algorithms BIBREF5 , BIBREF6 , and integer linear programming BIBREF7 .\nIn this work we propose a data-driven approach to summarization based on neural networks and continuous sentence features. There has been a surge of interest recently in repurposing sequence transduction neural network architectures for NLP tasks such as machine translation BIBREF8 , question answering BIBREF9 , and sentence compression BIBREF10 . Central to these approaches is an encoder-decoder architecture modeled by recurrent neural networks. The encoder reads the source sequence into a list of continuous-space representations from which the decoder generates the target sequence. An attention mechanism BIBREF11 is often used to locate the region of focus during decoding.\nWe develop a general framework for single-document summarization which can be used to extract sentences or words. Our model includes a neural network-based hierarchical document reader or encoder and an attention-based content extractor. The role of the reader is to derive the meaning representation of a document based on its sentences and their constituent words. Our models adopt a variant of neural attention to extract sentences or words. Contrary to previous work where attention is an intermediate step used to blend hidden units of an encoder to a vector propagating additional information to the decoder, our model applies attention directly to select sentences or words of the input document as the output summary. Similar neural attention architectures have been previously used for geometry reasoning BIBREF12 , under the name Pointer Networks.\nOne stumbling block to applying neural network models to extractive summarization is the lack of training data, i.e., documents with sentences (and words) labeled as summary-worthy. Inspired by previous work on summarization BIBREF7 , BIBREF13 and reading comprehension BIBREF9 we retrieve hundreds of thousands of news articles and corresponding highlights from the DailyMail website. Highlights usually appear as bullet points giving a brief overview of the information contained in the article (see Figure 1 for an example). Using a number of transformation and scoring algorithms, we are able to match highlights to document content and construct two large scale training datasets, one for sentence extraction and the other for word extraction. Previous approaches have used small scale training data in the range of a few hundred examples.\nOur work touches on several strands of research within summarization and neural sequence modeling. The idea of creating a summary by extracting words from the source document was pioneered in bankoetal00 who view summarization as a problem analogous to statistical machine translation and generate headlines using statistical models for selecting and ordering the summary words. Our word-based model is similar in spirit, however, it operates over continuous representations, produces multi-sentence output, and jointly selects summary words and organizes them into sentences. A few recent studies BIBREF14 , BIBREF15 perform sentence extraction based on pre-trained sentence embeddings following an unsupervised optimization paradigm. Our work also uses continuous representations to express the meaning of sentences and documents, but importantly employs neural networks more directly to perform the actual summarization task.\nrush2015neural propose a neural attention model for abstractive sentence compression which is trained on pairs of headlines and first sentences in an article. In contrast, our model summarizes documents rather than individual sentences, producing multi-sentential discourse. A major architectural difference is that our decoder selects output symbols from the document of interest rather than the entire vocabulary. This effectively helps us sidestep the difficulty of searching for the next output symbol under a large vocabulary, with low-frequency words and named entities whose representations can be challenging to learn. Gu:ea:16 and gulcehre2016pointing propose a similar “copy” mechanism in sentence compression and other tasks; their model can accommodate both generation and extraction by selecting which sub-sequences in the input sequence to copy in the output.\nWe evaluate our models both automatically (in terms of Rouge) and by humans on two datasets: the benchmark DUC 2002 document summarization corpus and our own DailyMail news highlights corpus. Experimental results show that our summarizers achieve performance comparable to state-of-the-art systems employing hand-engineered features and sophisticated linguistic constraints.\nOur model includes a neural network-based hierarchical document reader or encoder and an attention-based content extractor.",

        "answer": "Because cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words.",
        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nAlthough at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words.",

        "evidence": "Recently, with the emergence of neural seq2seq models, abstractive summarization methods have seen great performance strides BIBREF0, BIBREF1, BIBREF2. However, complex neural summarization models with thousands of parameters usually require a large amount of training data. In fact, much of the neural summarization work has been trained and tested in news domains where numerous large datasets exist. For example, the CNN/DailyMail (CNN/DM) BIBREF3, BIBREF4 and New York Times (NYT) datasets are in the magnitude of 300k and 700k documents, respectively. In contrast, in other domains such as student reflections, summarization datasets are only in the magnitude of tens or hundreds of documents (e.g., BIBREF5). We hypothesize that training complex neural abstractive summarization models in such domains will not yield good performing models, and we will indeed later show that this is the case for student reflections.\nTo improve performance in low resource domains, we explore three directions. First, we explore domain transfer for abstractive summarization. While domain transfer is not new, compared to prior summarization studies BIBREF6, BIBREF7, our training (news) and tuning (student reflection) domains are quite dissimilar, and the in-domain data is small. Second, we propose a template-based synthesis method to create synthesized summaries, then explore the effect of enriching training data for abstractive summarization using the proposed model compared to a synthesis baseline. Lastly, we combine both directions. Evaluations of neural abstractive summarization method across four student reflection corpora show the utility of all three methods.\nIn contrast, in other domains such as student reflections, summarization datasets are only in the magnitude of tens or hundreds of documents (e.g., (Luo and Litman 2015)).

For the sake of simplicity, we considered primarily the location-location and location-character/object relations, represented by the “next to” and “has” edges respectively in Figure FIGREF4.\nWhile many neural models already exist that perform similar tasks such as named entity extraction and part of speech tagging, they often come at the cost of large amounts of specialized labeled data suited for that task. We instead propose a new method that leverages models trained for context-grounded question-answering tasks to do entity extraction with no task dependent data or fine-tuning necessary. Our method, dubbed AskBERT, leverages the Question-Answering (QA) model ALBERT BIBREF15. AskBERT consists of two main steps as shown in Figure FIGREF7: vertex extraction and graph construction.\nThe first step is to extract the set of entities—graph vertices—from the story. We are looking to extract information specifically regarding characters, locations, and objects. This is done by using asking the QA model questions such as “Who is a character in the story?”. BIBREF16 have shown that the phrasing of questions given to a QA model is important and this forms the basis of how we formulate our questions—questions are asked so that they are more likely to return a single answer, e.g. asking “Where is a location in the story?” as opposed to “Where are the locations in the story?”. In particular, we notice that pronoun choice can be crucial; “Where is a location in the story?” yielded more consistent extraction than “What is a location in the story?”. ALBERT QA is trained to also output a special <$no$-$answer$> token when it cannot find an answer to the question within the story. Our method makes use of this by iteratively asking QA model a question and masking out the most likely answer outputted on the previous step. This process continues until the <$no$-$answer$> token becomes the most likely answer.\nThe next step is graph construction. Typical interactive fiction worlds are usually structured as trees, i.e. no cycles except between locations. Using this fact, we use an approach that builds a graph from the vertex set by one relation—or edge—at a time. Once again using the entire story plot as context, we query the ALBERT-QA model picking a random starting location $x$ from the set of vertices previously extracted.and asking the questions “What location can I visit from $x$?” and “Who/What is in $x$?”. The methodology for phrasing these questions follows that described for the vertex extraction. The answer given by the QA model is matched to the vertex set by picking the vertex $u$ that contains the best word-token overlap with the answer. Relations between vertices are added by computing a relation probability on the basis of the output probabilities of the answer given by the QA model. The probability that vertices $x,u$ are related:\nWe compared our proposed AskBERT method with a non-neural, rule-based approach. This approach is based on the information extracted by OpenIE5, followed by some post-processing such as named-entity recognition and part-of-speech tagging. OpenIE5 combines several cutting-edge ideas from several existing papers BIBREF17, BIBREF18, BIBREF19 to create a powerful information extraction tools. For a given sentence, OpenIE5 generates multiple triples in the format of $\\langle entity, relation, entity\\rangle $ as concise representations of the sentence, each with a confidence score. These triples are also occasionally annotated with location information indicating that a triple happened in a location.\nAs in the neural AskBERT model, we attempt to extract information regarding locations, characters, and objects. The entire story plot is passed into the OpenIE5 and we receive a set of triples. The location annotations on the triples are used to create a set of locations. We mark which sentences in the story contain these locations. POS tagging based on marking noun-phrases is then used in conjunction with NER to further filter the set of triples—identifying the set of characters and objects in the story.\nThe graph is constructed by linking the set of triples on the basis of the location they belong to. While some sentences contain very explicit location information for OpenIE5 to mark it out in the triples, most of them do not. We therefore make the assumption that the location remains the same for all triples extracted in between sentences where locations are explicitly mentioned. For example, if there exists $location A$ in the 1st sentence and $location B$ in the 5th sentence of the story, all the events described in sentences 1-4 are considered to take place in $location A$. The entities mentioned in these events are connected to $location A$ in the graph.\nThe first phase is to extract a knowledge graph from the story that depicts locations, characters, objects, and the relations between these entities.

The most important setting that will determine the depth of focus is the aperture used in the lens when the picture is taken. The aperture is how widely open the lens is and how much light is allowed to pass through it.

Most political event datasets are dominated by low-level political events that lack a strong valence. These are usually routine events such as statements that occur often. Figures 4 and 5 show the breakdown of event types within the current Phoenix data, both of which confirm this existing pattern. The addition of the 0 quad class category was designed to capture these types of events so that they can be easily removed to allow end users to easily focus on more substantive political events. Following these lower-level event types, the event codes 19 and 17, “Fight” and “Coerce” respectively, are the next most common. The prevalence of 19 codes is unsurprising given that the underlying dictionaries were structured in such a way that many events defaulted to this category.\nIssue coding based on simple keyword lookups is used in Phoenix to provide further context to events. Figure 5 shows that the most common theme in the issue codings is terrorist organizations, followed by general security topics and the European Union. The hope for these issue codings is that events that might not have clear actors can be further illuminated by an issue coding, such as in the case of an attack against an unspecified armed group that could also have the issue coding of “Terror Group.”\nAs has been noted, events are coded on two primary dimensions: event codes and actors.",

        "evidence": "In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time. A decrease in cost per unit of output enables an increase in scale. At the basis of economies of scale, there may be technical, statistical, organizational or related factors to the degree of market control. This is just a partial description of the concept.\n\nEconomies of scale apply to a variety of the organizational and business situations and at various levels, such as a production, plant or an entire enterprise. When average costs start falling as output increases, then economies of scale occur. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis.\n\nThe economic concept dates back to Adam Smith and the idea of obtaining larger production returns through the use of division of labor. Diseconomies of scale are the opposite.\n\nEconomies of scale often have limits, such as passing the optimum design point where costs per additional unit begin to increase. Common limits include exceeding the nearby raw material supply, such as wood in the lumber, pulp and paper industry. A common limit for a low cost per unit weight commodities is saturating the regional market, thus having to ship product uneconomic distances. Other limits include using energy less efficiently or having a higher defect rate.\n\nLarge producers are usually efficient at long runs of a product grade (a commodity) and find it costly to switch grades frequently. They will, therefore, avoid specialty grades even though they have higher margins. Often smaller (usually older) manufacturing facilities remain viable by changing from commodity-grade production to specialty products.\n\nEconomies of scale must be distinguished from economies stemming from an increase in the production of a given plant. When a plant is used below its optimal production capacity, increases in its degree of utilization bring about decreases in the total average cost of production. As noticed, among the others, by Nicholas Georgescu-Roegen (1966) and Nicholas Kaldor (1972) these economies are not economies of scale.",
        "answer": "Examples of diseconomies of scale include: using energy less efficiently, over-saturating a regional market, exceeding the local raw material supply, higher production switching costs leading to inability to pivot to higher margin products (reduced agility), and having a higher defect rate.",

        "question": "Do the MBN features perform relatively poorly compared to the standard MFCC?",

        "evidence": "First, we evaluated the standard HMM model with an uninformative prior (this will be our baseline) for the two different input features: MFCC (and derivatives) and MBN. Results are shown in Table TABREF20 . Surprisingly, the MBN features perform relatively poorly compared to the standard MFCC. These results are contradictory to those reported in BIBREF3 . Two factors may explain this discrepancy: the Mboshi5k data being different from the training data of the MBN neural network, the neural network may not generalize well. Another possibility may be that the initialization scheme of the model is not suitable for this type of features. Indeed, Variational Bayesian Inference algorithm converges only to a local optimum of the objective function and is therefore dependent of the initialization. We believe the second explanation is the more likely since, as we shall see shortly, the best results in term of word segmentation and NMI are eventually obtained with the MBN features when the inference is done with the informative prior. Next, we compared the HMM and the SVAE models when trained with an uninformative prior (lines with \"Inf. Prior\" set to \"no\" in Table TABREF23 ). The SVAE significantly improves the NMI and the precision showing that it extracts more consistent units than the HMM model. However, it also degrades the segmentation in terms of recall. We further investigated this behavior by looking at the duration of the units found by both models compared to the true phones (Table TABREF22 ). We observe that the SVAE model favors longer units than the HMM model hence leading to fewer boundaries and consequently smaller recall.\nWe then evaluated the effect of the informative prior on the acoustic unit discovery (Table TABREF23 ). On all 4 combinations (2 features sets INLINEFORM0 2 models) we observe an improvement in terms of precision and NMI but a degradation of the recall. This result is encouraging since the informative prior was trained on English data (TIMIT) which is very different from Mboshi. Indeed, this suggests that even speech from an unrelated language can be of some help in the design of an ASR for a very low resource language. Finally, similarly to the SVAE/HMM case described above, we found that the degradation of the recall is due to longer units discovered for models with an informative prior (numbers omitted due to lack of space).\nWord discovery results are given in Table TABREF21 for the Boundary metric BIBREF20 , BIBREF21 . We observe that i) the best word boundary detection (F-score) is obtained with MBN features, an informative prior and the SVAE model; this confirms the results of table TABREF23 and shows that better AUD leads to better word segmentation ii) word segmentation from AUD graph Lattices is slightly better than from flat sequences of AUD symbols (1-best); iii) our results outperform a pure speech based baseline based on segmental DTW BIBREF22 (F-score of 19.3% on the exact same corpus).\nResults are shown in Table 1.

For example, we may read that exercise improves health, and thus decide to spend more time at the gym; or that larger cars cause more pollution, and thus decide to buy a smaller car to be environmentally sensitive. These skills require understanding the underlying qualitative relationships, and being able to apply them in specific contexts.\nTo promote research in this direction, we present the first open-domain dataset of qualitative relationship questions, called QuaRTz (“Qualitative Relationship Test set”). Unlike earlier work in qualitative reasoning, e.g., BIBREF0, the dataset is not restricted to a small, fixed set of relationships. Each question $Q_i$ (2-way multiple choice) is grounded in a particular situation, and is paired with a sentence $K_i$ expressing the general qualitative knowledge needed to answer it. $Q_i$ and $K_i$ are also annotated with the properties being compared (Figure FIGREF1). The property annotations serve as supervision for a potential semantic parsing based approach. The overall task is to answer the $Q_i$ given the corpus $K = \\lbrace K_i\\rbrace $.\nWe test several state-of-the-art (BERT-based) models and find that they are still substantially (20%) below human performance.

It contrasts with previous seq2seq models, which usually rely either on costly gated recurrent operations BIBREF15, BIBREF16 or static convolutions BIBREF17.\nGiven $n$ query contexts and $m$ sequence items under consideration, attention mechanisms compute, for each query, a weighted representation of the items. The particular attention mechanism used in BIBREF0 is called scaled dot-product attention, and it is computed in the following way:\nwhere $\\mathbf {Q} \\in \\mathbb {R}^{n \\times d}$ contains representations of the queries, $\\mathbf {K}, \\mathbf {V} \\in \\mathbb {R}^{m \\times d}$ are the keys and values of the items attended over, and $d$ is the dimensionality of these representations.

It lies in the Karakoram range, partially in the Gilgit-Baltistan region of Pakistan-administered Kashmir and partially in a China-administered territory Trans-Karakoram Tract included in the Taxkorgan Tajik Autonomous County of Xinjiang.\n\nK2 also became popularly known as the Savage Mountain after George Bell—a climber on the 1953 American expedition—told reporters, \"It's a savage mountain that tries to kill you.\" Of the five highest mountains in the world, K2 is the deadliest; approximately one person dies on the mountain for every four who reach the summit. Also occasionally known as Mount Godwin-Austen, other nicknames for K2 are The King of Mountains and The Mountaineers' Mountain, as well as The Mountain of Mountains after prominent Italian climber Reinhold Messner titled his book about K2 the same.\n\nThe summit was reached for the first time by the Italian climbers Lino Lacedelli and Achille Compagnoni, on the 1954 Italian expedition led by Ardito Desio. In January 2021, K2 became the final eight-thousander to be summited in the winter; the mountaineering feat was accomplished by a team of Nepalese climbers, led by Nirmal Purja and Mingma Gyalje Sherpa.\n\nK2 is the only 8,000+ metres (26,000+ ft) peak that has never been climbed from its eastern face. Ascents have almost always been made in July and August, which are typically the warmest times of the year; K2's more northern location makes it more susceptible to inclement and colder weather. The peak has now been climbed by almost all of its ridges. Although the summit of Everest is at a higher altitude, K2 is a more difficult and dangerous climb, due in part to its more inclement weather. As of February 2021, only 377 people have completed the ascent to its summit. There have been 91 deaths during attempted climbs.\n\nThere are a number of routes on K2, of somewhat different character, but they all share some key difficulties, the first being the extremely high altitude and resulting lack of oxygen: there is only one-third as much oxygen available to a climber on the summit of K2 as there is at sea level. The second is the propensity of the mountain to experience extreme storms of several days duration, which have resulted in many of the deaths on the peak. The third is the steep, exposed, and committing nature of all routes on the mountain, which makes retreat more difficult, especially during a storm. Despite many attempts the first successful winter ascents occurred only in 2021. All major climbing routes lie on the Pakistani side.[citation needed] The base camp is also located on the Pakistani side.",

In addition to the lack of oxygen experienced at such high altitudes, all routes to summit K2 are steep with significant exposure.  This exposure, combined with the mountain's propensity to experience extreme storms lasting for days, make for a deadly combination.

        "answer": "The authors performed classification experiments on the Italian dataset using the LR classifier and different size classes.",
        "evidence": "We performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty; this also allows us to compare results with our baseline. We applied a standardization of the features and we used the default configuration for parameters as described in scikit-learn package BIBREF33. We also tested other classifiers (such as K-Nearest Neighbors, Support Vector Machines and Random Forest) but we omit results as they give comparable performances. We remark that our goal is to show that a very simple machine learning framework, with no parameter tuning and optimization, allows for accurate results with our network-based approach.\nWe used the following evaluation metrics to assess the performances of different classifiers (TP=true positives, FP=false positives, FN=false negatives):\nPrecision = $\\frac{TP}{TP+FP}$, the ability of a classifier not to label as positive a negative sample.\nRecall = $\\frac{TP}{TP+FN}$, the ability of a classifier to retrieve all positive samples.\nF1-score = $2 \\frac{\\mbox{Precision} \\cdot \\mbox{Recall}}{\\mbox{Precision} + \\mbox{Recall}}$, the harmonic average of Precision and Recall.\nArea Under the Receiver Operating Characteristic curve (AUROC); the Receiver Operating Characteristic (ROC) curve BIBREF34, which plots the TP rate versus the FP rate, shows the ability of a classifier to discriminate positive samples from negative ones as its threshold is varied; the AUROC value is in the range $[0, 1]$, with the random baseline classifier holding AUROC$=0.5$ and the ideal perfect classifier AUROC$=1$; thus larger AUROC values (and steeper ROCs) correspond to better classifiers.\nIn particular we computed so-called macro average–simple unweighted mean–of these metrics evaluated considering both labels (disinformation and mainstream). We employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.\nFinally, we partitioned networks according to the total number of unique users involved in the sharing, i.e. the number of nodes in the aggregated network represented with a single-layer representation considering together all layers and also pure tweets. A breakdown of both datasets according to size class (and political biases for the US scenario) is provided in Table 1 and Table 2.\nIn Table 3 we first provide classification performances on the US dataset for the LR classifier evaluated on the size class described in Table 1. We can observe that in all instances our methodology performs better than a random classifier (50% AUROC), with AUROC values above 85% in all cases.\nFor what concerns political biases, as the classes of mainstream and disinformation networks are not balanced (e.g., 1,292 mainstream and 4,149 disinformation networks with right bias) we employ a Balanced Random Forest with default parameters (as provided in imblearn Python package BIBREF35). In order to test the robustness of our methodology, we trained only on left-biased networks or right-biased networks and tested on the entire set of sources (relative to the US dataset); we provide a comparison of AUROC values for both biases in Figure 4. We can notice that our multi-layer approach still entails significant results, thus showing that it can accurately distinguish mainstream news from disinformation regardless of the political bias. We further corroborated this result with additional classification experiments, that show similar performances, in which we excluded from the training/test set two specific sources (one at a time and both at the same time) that outweigh the others in terms of data samples–respectively \"breitbart.com\" for right-biased sources and \"politicususa.com\" for left-biased ones.\nWe performed classification experiments on the Italian dataset using the LR classifier and different size classes (we excluded $[1000, +\\infty )$ which is empty); we show results for different evaluation metrics in Table 3. We can see that despite the limited number of samples (one order of magnitude smaller than the US dataset) the performances are overall in accordance with the US scenario. As shown in Table 4, we obtain results which are much better than our baseline in all size classes (see Table 4):\nIn the US dataset our multi-layer methodology performs much better in all size classes except for large networks ($[1000, +\\infty )$ size class), reaching up to 13% improvement on smaller networks ($[0, 100)$ size class);\nIn the IT dataset our multi-layer methodology outperforms the baseline in all size classes, with the maximum performance gain (20%) on medium networks ($[100, 1000)$ size class); the baseline generally reaches bad performances compared to the US scenario.\nOverall, our performances are comparable with those achieved by two state-of-the-art deep learning models for \"fake news\" detection BIBREF9BIBREF36.\nIn order to understand the impact of each layer on the performances of classifiers, we performed additional experiments considering separately each layer (we ignored T and U features relative to pure tweets). In Table 5 we show metrics for each layer and all size classes, computed with a 10-fold stratified shuffle split cross validation, evaluated on the US dataset; in Figure 5 we show AUROC values for each layer compared with the general multi-layer approach. We can notice that both Q and M layers alone capture adequately the discrepancies of the two distinct news domains in the United States as they obtain good results with AUROC values in the range 75%-86%; these are comparable with those of the multi-layer approach which, nevertheless, outperforms them across all size classes.\nWe obtained similar performances for the Italian dataset, as the M layer obtains comparable performances w.r.t multi-layer approach with AUROC values in the range 72%-82%. We do not show these results for sake of conciseness.\nWe further investigated the importance of each feature by performing a $\\chi ^2$ test, with 10-fold stratified shuffle split cross validation, considering the entire range of network sizes $[0, +\\infty )$. We show the Top-5 most discriminative features for each country in Table 6.\nWe can notice the exact same set of features (with different relative orderings in the Top-3) in both countries; these correspond to two global network propertie–LWCC, which indicates the size of the largest cascade in the layer, and SCC, which correlates with the size of the network–associated to the same set of layers (Quotes, Retweets and Mentions).\nWe further performed a $\\chi ^2$ test to highlight the most discriminative features in the M layer of both countries, which performed equally well in the classification task as previously highlighted; also in this case we focused on the entire range of network sizes $[0, +\\infty )$. Interestingly, we discovered exactly the same set of Top-3 features in both countries, namely LWCC, SCC and DWCC (which indicates the depth of the largest cascade in the layer).\nAn inspection of the distributions of all aforementioned features revealed that disinformation news exhibit on average larger values than mainstream news.\nWe can qualitatively sum up these results as follows:\nSharing patterns in the two news domains exhibit discrepancies which might be country-independent and due to the content that is being shared.\nInteractions in disinformation sharing cascades tends to be broader and deeper than in mainstream news, as widely reported in the literature BIBREF8BIBREF2BIBREF7.\nUsers likely make a different usage of mentions when sharing news belonging to the two domains, consequently shaping different sharing patterns.\nSimilar to BIBREF9, we carried out additional experiments to answer the following question: how long do we need to observe a news spreading on Twitter in order to accurately classify it as disinformation or mainstream?\nWith this goal, we built several versions of our original dataset of multi-layer networks by considering in turn the following lifetimes: 1 hour, 6 hours, 12 hours, 1 day, 2 days, 3 days and 7 days; for each case, we computed the global network properties of the corresponding network and evaluated the LR classifier with 10-fold cross validation, separately for each lifetime (and considering always the entire set of networks). We show corresponding AUROC values for both US and IT datasets in Figure 6.\nWe can see that in both countries news diffusion networks can be accurately classified after just a few hours of spreading, with AUROC values which are larger than 80% after only 6 hours of diffusion. These results are very promising and suggest that articles pertaining to the two news domains exhibit discrepancies in their sharing patterns that can be timely exploited in order to rapidly detect misleading items from factual information.\nWe performed classification experiments on the Italian dataset using the LR classifier and different size classes (we excluded [1000, +∞) which is empty);",

Starting from the idealized schema, we create a rule-based tool for converting UD-schema annotations to UniMorph annotations, incorporating language-specific post-edits that both correct infelicities and also increase harmony between the datasets themselves (rather than the schemata). We apply this conversion to the 31 languages with both UD and UniMorph data, and we report our method's recall, showing an improvement over the strategy which just maps corresponding schematic features to each other. Further, we show similar downstream performance for each annotation scheme in the task of morphological tagging.\nFLOAT SELECTED: Table 3: Token-level recall when converting Universal Dependencies tags to UniMorph tags. CSV refers to the lookup-based system. Post-editing refers to the proposed method.\nThere are three other transformations for which we note no improvement here. Because of the problem in Basque argument encoding in the UniMorph dataset—which only contains verbs—we note no improvement in recall on Basque. Irish also does not improve: UD marks gender on nouns, while UniMorph marks case. Adjectives in UD are also underspecified. The verbs, though, are already correct with the simple mapping. Finally, with Dutch, the UD annotations are impoverished compared to the UniMorph annotations, and missing attributes cannot be inferred without external knowledge.\nWe present the intrinsic task's recall scores in tab:recall. Bear in mind that due to annotation errors in the original corpora (like the vas example from sec:resources), the optimal score is not always $100\\%$ . Some shortcomings of recall come from irremediable annotation discrepancies. Largely, we are hamstrung by differences in choice of attributes to annotate. When one resource marks gender and the other marks case, we can't infer the gender of the word purely from its surface form. The resources themselves would need updating to encode the relevant morphosyntactic information. Some languages had a very low number of overlapping forms, and no tag matches or near-matches between them: Arabic, Hindi, Lithuanian, Persian, and Russian. A full list of observed, irremediable discrepancies is presented alongside the codebase.\nFor the extrinsic task, the performance is reasonably similar whether UniMorph or UD; see tab:tagging. A large fluctuation would suggest that the two annotations encode distinct information. On the contrary, the similarities suggest that the UniMorph-mapped MSDs have similar content. We recognize that in every case, tagging F1 increased—albeit by amounts as small as $0.16$ points. This is in part due to the information that is lost in the conversion. UniMorph's schema does not indicate the type of pronoun (demonstrative, interrogative, etc.), and when lexical information is not recorded in UniMorph, we delete it from the MSD during transformation. On the other hand, UniMorph's atomic tags have more parts to guess, but they are often related. (E.g. Ipfv always entails Pst in Spanish.)

BIBREF4 BIBREF4 surveys the methods in query-document matching in web search which focuses on the topic model, the dependency model, etc. However, none of them pays attention to the query-bag matching which concentrates on the matching for a query and a bag containing multiple questions.\nWhen a user poses a query to the bot, the bot searches the most similar bag and uses the corresponding answer to reply to the user. The more information in the query covered by the bag, the more likely the bag's corresponding answer answers the query. What's more, the bag should not have too much information exceeding the query. Thus modelling the bag-to-query and query-to-bag coverage is essential in this task.\nIn this paper, we propose a simple but effective mutual coverage component to model the above-mentioned problem. The coverage is based on the cross-attention matrix of the query-bag pair which indicates the matching degree of elements between the query and bag. The mutual coverage is performed by stacking the cross-attention matrix along two directions, i.e., query and bag, in the word level respectively. In addition to the mutual coverage, a bag representation in word level is issued to help discover the main points of a bag. The bag representation then provides new matching evidence to the query-bag matching model.\nWe conduct experiments on the AliMe and Quora dataset for the query-bag matching based information-seeking conversation. Compared with baselines, we verify the effectiveness of our model. Our model obtains 0.05 and 0.03 $\\text{R}_{10}@1$ gains comparing to the strongest baseline in the two datasets. The ablation study shows the usefulness of the components. The contributions in this paper are summarized as follows: 1) To the best of our knowledge, we are the first to adopt query-bag matching in the information-seeking conversation. 2) We propose the mutual coverage model to measure the information coverage in the query-bag matching. 3) We release the composite Quora dataset to facilitate the research in this area.\nThrough data analysis, we find that many variants of a question exist which means a sort of questions can correspond to a same answer.",

        "answer": "Character-level encoder-decoder framework.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nIn this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.",

To model the role ordering and repetition preferences, the role inventory for each predicate is divided into Primary and Secondary roles as follows:\n\nFor example, the complete role sequence in a frame could be: INLINEFORM0 INLINEFORM1 , INLINEFORM2 , INLINEFORM3 , INLINEFORM4 , INLINEFORM5 , INLINEFORM6 , INLINEFORM7 , INLINEFORM8 INLINEFORM9 . The ordering is defined as the sequence of PRs, INLINEFORM10 INLINEFORM11 , INLINEFORM12 , INLINEFORM13 , INLINEFORM14 , INLINEFORM15 INLINEFORM16 . Each pair of consecutive PRs in an ordering is called an interval. Thus, INLINEFORM17 is an interval that contains two SRs, INLINEFORM18 and INLINEFORM19 . An interval could also be empty, for instance INLINEFORM20 contains no SRs. When we evaluate, these roles get mapped to gold roles. For instance, the PR INLINEFORM21 could get mapped to a core role like INLINEFORM22 , INLINEFORM23 , etc. or to a modifier role like INLINEFORM24 , INLINEFORM25 , etc. garg2012unsupervised reported that, in practice, PRs mostly get mapped to core roles and SRs to modifier roles, which conforms to the linguistic motivations for this distinction.\nFigure FIGREF16 illustrates two copies of the monolingual model, on either side of the crosslingual latent variables. The generative process is as follows:\n\nAll the multinomial and binomial distributions have symmetric Dirichlet and beta priors respectively. Figure FIGREF7 gives the probability equations for the monolingual model. This formulation models the global role ordering and repetition preferences using PRs, and limited context for SRs using intervals.

        "evidence": "The task of interpreting and following natural language (NL) navigation instructions involves interleaving different signals, at the very least the linguistic utterance and the representation of the world. For example, in turn right on the first intersection, the instruction needs to be interpreted, and a specific object in the world (the intersection) needs to be located in order to execute the instruction. In NL navigation studies, the representation of the world may be provided via visual sensors BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4 or as a symbolic world representation. This work focuses on navigation based on a symbolic world representation (referred to as a map).\nPrevious datasets for NL navigation based on a symbolic world representation, HCRC BIBREF5, BIBREF6, BIBREF7 and SAIL BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15 present relatively simple worlds, with a small fixed set of entities known to the navigator in advance. Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes. Using Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers. This task raises several challenges. First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map.",

It aired on NBC from July 5, 1989, to May 14, 1998, over nine seasons and 180 episodes. It stars Seinfeld as a fictionalized version of himself and focuses on his personal life with three of his friends: best friend George Costanza (Jason Alexander), former girlfriend Elaine Benes (Julia Louis-Dreyfus) and his neighbor from across the hall, Cosmo Kramer (Michael Richards). It is set mostly in an apartment building in Manhattan's Upper West Side in New York City. It has been described as \"a show about nothing\", often focusing on the minutiae of daily life. Interspersed in earlier episodes are moments of stand-up comedy from the fictional Jerry Seinfeld, frequently using the episode's events for material.\n\nAs a rising comedian in the late 1980s, Jerry Seinfeld was presented with an opportunity to create a show with NBC. He asked Larry David, a fellow comedian and friend, to help create a premise for a sitcom. The series was produced by West-Shapiro Productions and Castle Rock Entertainment and distributed by Columbia Pictures Television.[nb 1] It was largely written by David and Seinfeld, with script writers who included Larry Charles, Peter Mehlman, Gregg Kavet, Carol Leifer, David Mandel, Jeff Schaffer, Steve Koren, Jennifer Crittenden, Tom Gammill, Max Pross, Dan O'Keefe, Charlie Rubin, Marjorie Gross, Alec Berg, Elaine Pope and Spike Feresten. A favorite among critics, the series led the Nielsen ratings in Seasons 6 and 9 and finished among the top two (with NBC's ER) every year from 1994 to 1998. Only two other shows – I Love Lucy and The Andy Griffith Show – have finished their runs at the top of the ratings.\n\nSeinfeld is widely regarded as one of the greatest and most influential sitcoms of all time. It has been ranked among television's best shows in publications such as Entertainment Weekly, Rolling Stone and TV Guide. Its most renowned episodes include \"The Chinese Restaurant\", \"The Soup Nazi\", \"The Parking Garage\", \"The Marine Biologist\" and \"The Contest\". In 2013, the Writers Guild of America voted it the No. 2 Best-Written TV Series of All Time (second to The Sopranos).

These classifiers are targeted by white-box attacking methods to generate adversarial examples (detailed in Section SECREF9). BiLSTM is composed of an embedding layer that maps individual words to pre-trained word embeddings; a number of bi-directional LSTMs that capture sequential contexts; and an output layer that maps the averaged LSTM hidden states to a binary output. BiLSTM$+$A is similar to BiLSTM except it has an extra self-attention layer which learns to attend to salient words for sentiment classification, and we compute a weighted mean of the LSTM hidden states prior to the output layer.

There are three methods to identify morphemes in Vietnamese text BIBREF10 .\nMorpheme is the smallest meaningful unit of Vietnamese.\nMorpheme is the basic unit of Vietnamese.\nMorpheme is the smallest meaningful unit and is not used independently in the syntax factor.\nIn computational linguistics, morpheme is the basic unit of languages as Leonard Bloomfield mentioned for English BIBREF11 . In our research for Vietnamese, we consider the morpheme as syllable, called “tiếng” in Vietnamese (as Nguyen’s definition BIBREF12 ).\nThe next concept in linguistics is word which has fully grammar and meaning function in sentences. For Vietnamese, word is a single morpheme or a group of morphemes, which are fixed and have full meaning BIBREF12 . According to Nguyen, Vietnamese words are able classified into two types, (1) 1- syllable words with fully meaning and (2) n-syllables words whereas these group of tokens are fixed. Vietnamese syllable is not fully meaningful. However, it is also explained in the meaning and structure characteristics. For example, the token “kỳ” in “quốc kỳ” whereas “quốc” means national, “kỳ” means flag. Therefore, “quốc kỳ” means national flag.\nConsider dictionary used for evaluating the corpus, extracting features for models, and evaluating the systems, there are many Vietnamese dictionaries, however we recommend the Vietnamese dictionary of Hoang Phe, so called Hoang Phe Dictionary. This dictionary has been built by a group of linguistical scientists at the Linguistic Institute, Vietnam. It was firstly published in 1988, reprinted and extended in 2000, 2005 and 2010. The dictionary currently has 45,757 word items with 15,901 Sino-Vietnamese word items (accounting for 34.75%) BIBREF13 .\nThe most basic linguistic unit in Vietnamese is morpheme, similar with syllable or token in English and “hinh vj” (phoneme) or “tieng^ (syllable) in Vietnamese.",

        "question": "Why have many methods been proposed to improve the performance of UNMT in recent?",
        "answer": "Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.",
        "evidence": "In recent years, zero-shot translation in NMT has attracted widespread attention in academic research. Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.\nPivot-based Method is a common strategy to obtain a source$\\rightarrow $target model by introducing a pivot language. This approach is further divided into pivoting and pivot-synthetic. While the former firstly translates a source language into the pivot language which is later translated to the target language BIBREF4, BIBREF5, BIBREF12, the latter trains a source$\\rightarrow $target model with pseudo data generated from source-pivot or pivot-target parallel data BIBREF13, BIBREF14. Although the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter-vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation problem BIBREF15.\nTransfer Learning is firstly introduced for NMT by BIBREF6, which leverages a high-resource parent model to initialize the low-resource child model. On this basis, BIBREF7 and BIBREF8 use shared vocabularies for source/target language to improve transfer learning, while BIBREF16 relieve the vocabulary mismatch by mainly using cross-lingual word embedding. Although these methods are successful in the low-resource scene, they have limited effects in zero-shot translation.\nMultilingual NMT (MNMT) enables training a single model that supports translation from multiple source languages into multiple target languages, even those unseen language pairs BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21. Aside from simpler deployment, MNMT benefits from transfer learning where low-resource language pairs are trained together with high-resource ones. However, BIBREF22 point out that MNMT for zero-shot translation easily fails, and is sensitive to the hyper-parameter setting. Also, MNMT usually performs worse than the pivot-based method in zero-shot translation setting BIBREF23.\nUnsupervised NMT (UNMT) considers a harder setting, in which only large-scale monolingual corpora are available for training. Recently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training BIBREF24, BIBREF25, BIBREF26, BIBREF11. Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.\nOur proposed method belongs to the transfer learning, but it is different from traditional transfer methods which train a parent model as starting point. Before training a parent model, our approach fully leverages cross-lingual pre-training methods to make all source languages share the same feature space and thus enables a smooth transition for zero-shot translation.\nRecently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training (Artetxe et al. 2017;   Lample et al. 2018;   Ren et al. 2019;   Lample and Conneau 2019).

If negative sum is larger than or equal to the positive sum, the review is labeled as a negative review.",
        "evidence": "For experimental results, we report majority baseline for each language where the majority baseline corresponds to a model's accuracy if it always predicts the majority class in the dataset. For example, if the dataset has 60% of all reviews positive and 40% negative, majority baseline would be 60% because a model that always predicts “positive” will be 60% accurate and will make mistakes 40% of the time.\nIn addition to the majority baseline, we also compare our results with a lexicon-based approach. We use SentiWordNet BIBREF29 to obtain a positive and a negative sentiment score for each token in a review. Then sum of positive sentiment scores and negative sentiment scores for each review is obtained by summing up the scores for each token. If the positive sum score for a given review is greater than the negative sum score, we accept that review as a positive review. If negative sum is larger than or equal to the positive sum, the review is labeled as a negative review.\nRNN outperforms both baselines in all four datasets (see Table TABREF9 ). Also for Spanish restaurant review, the lexicon-based baseline is below the majority baseline which shows that solely translating data and using lexicons is not sufficient to achieve good results in multilingual sentiment analysis.\nAmong the wrong classifications for each test set, we calculated the percentage of false positives and false negatives. Table TABREF10 shows the distribution of false positives and false negatives for each class. In all four classes, the number of false negatives are more than the number of false positives. This can be explained by the unbalanced training dataset where the number of positive reviews are more than the number of negative reviews (59,577 vs 17,132).\nTo be able to see the difference between baseline and RNN, we took each method's results as a group (4 values: one for each language) and compared the means. Post hoc comparisons using the Tukey HSD test indicated that the mean accuracies for baselines (majority and lexicon-based) are significantly different than RNN accuracies as can be seen in Table TABREF12 (family-wise error rate=0.06). When RNN is compared with lexicon-based baseline and majority baseline, the null hypothesis can be rejected meaning that each test is significant. In addition to these comparisons, we also calculated the effect sizes (using Cohen's d) between the baselines and our method. The results are aligning with Tukey HSD results such that while our method versus baselines have very large effect sizes, lexicon-based baseline and majority baseline have negligible effect size.\nFigure FIGREF11 shows the differences in minimum and maximum values of all three approaches. As the figure shows, RNN significantly outperforms both baselines for the sentiment classification task.\nWe use SentiWordNet to obtain a positive and a negative sentiment score for each token in a review. Then sum of positive sentiment scores and negative sentiment scores for each review is obtained by summing up the scores for each token.

        "question": "Why are there so many rules about table manners?",
        "evidence": "",
        "answer": "Well one big reason is that eating among other people is a social activity. In any social activity, there are guidelines for behavior. Mostly these guidelines are intended to make the social activity pleasant or fun for all the people involved. \nFor table manners, the rules are noticeably different among different cultures. Still, there are some common themes across cultures, for what is considered polite manners while eating. One common theme is to ensure that every person at the meal gets to eat. You can see this in the American table manner rule that nobody should not start eating until every person has been served their meal. In Mexican culture, any child who is nearby an outdoor party should be offered some of the party food. Another common theme about manners is that you should enjoy the food and the company, and not appear to simply be gobbling down as much food as possible. There are a lot of negative words to describe behavior that looks like eating too much or too fast, to be considered polite: being piggish, wolfing your food, gobbling, scarfing. \nOne rule that helps enforce slow eating, in American table manners, is that you shouldn't butter a whole piece of bread before eating it. Instead, you should tear the bread into smaller pieces, and butter only the piece you will eat next. Breaking the bread in half is considered a minimum level of politeness. Also, it's considered polite to leave one bite of each dish on your plate. If you eat everything, it could signal that you were just hungry, and eating everything available! But if you leave one bite, it signals \"I liked it, but had enough\". Americans also slow down eating by using both their fork and their knife in their right hands. This means that whenever you need to cut your food, you have to put down your fork, pick it up in your left hand, and pick up your knife in your right hand to cut your food. Before taking the bite, you have to do the opposite: put down your knife, pick up your fork in your right hand, and take your bite. This slows down eating a lot. (This rule is in contrast to table manners for the English, who keep their fork in their left hand and their knife in their right hand). Also, when eating soup, it's polite to push the spoon away from you, after filling it. Wipe the bottom of the spoon on the far side of your bowl, before bringing the spoonful of soup to your mouth. If you eat soup this way, you avoid scooping spoonfuls directly into your mouth -- which again, could look like you are just wolfing down food as fast as possible, instead of enjoying each mouthful.\nThere are also some table manner rules that provide signals to the servers or the waitstaff, without requiring verbal communications. For example, if you put down your fork pointing at 4:00 (with the handle pointing to the lower right of your plate), then it communicates \"I'm still eating\". But if you put your fork down, pointing at 10:00 or 11:00, then it communicates \"I'm finished with this food\". Then your server can take away your plate without interrupting the group conversation, which again is an example of making the social activity more pleasant for the participants. \nOverall, the rules of table manners evolved to make the social experience of eating a meal together a pleasant experience for everyone.",

        "evidence": "Pre-trained models BIBREF0, BIBREF1 have received much of attention recently thanks to their impressive results in many down stream NLP tasks. Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nOur main contributions in this work are: We propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.",

Empirical results show that the gradient-based method is superior to several black-box methods in estimating the word importance.

Our study also suggests the possibility of detecting the notorious under-translation problem via the gradient-based method.\nThis paper is an initiating step towards the general understanding of NMT models, which may bring some potential improvements, such as\nInteractive MT and Constraint Decoding BIBREF29, BIBREF26: The model pays more attention to the detected unimportant words, which are possibly under-translated;\nAdaptive Input Embedding BIBREF30: We can extend the adaptive softmax BIBREF31 to the input embedding of variable capacity – more important words are assigned with more capacity;\nNMT Architecture Design: The language-specific inductive bias (e.g., different behaviors on POS) should be incorporated into the model design.\nWe can also explore other applications of word importance to improve NMT models, such as more tailored training methods. In general, model interpretability can build trust in model predictions, help error diagnosis and facilitate model refinement. We expect our work could shed light on the NMT model understanding and benefit the model improvement.\nThere are many possible ways to implement the general idea of exploiting gradients for model interpretation. The aim of this paper is not to explore this whole space but simply to show that some fairly straightforward implementations work well. Our approach can benefit from advanced exploitation of the gradients or other useful intermediate information, which we leave to the future work.\nEmpirical results show that the gradient-based method is superior to several black-box methods in estimating the word importance.",

Johnstone recalls that he was a part of the 70s jogging craze in America and that after entering a few races he was not regaining his \"mediocre fitness\" despite having been a member of the 1957 Collegiate and AAU All-American swim teams. Then in 1973, Johnstone learned of the Dave Pain Birthday Biathlon, a 7.2 km (4.5 mi) run followed by what was billed as a quarter-mile (0.4 km) swim (the actual distance was only between 200 and 300 yards). The following year, after competing in the event for the second time and placing in the top ten, Johnstone desired more of this style of race and with equal emphasis on the swim. So he petitioned the chairman of the San Diego Track Club who told him he would add a race to the club calendar. But the rest of the race was up to Johnstone to organise, and at the same time he was to contact Don Shanahan so there wouldn't be too many \"weird\" races on the club schedule. Shanahan told Johnstone that he wanted to include a biking leg to the race; whilst hesitant Johnstone agreed to the addition. When naming the event the pair used the unofficially agreed naming system for multisport events, already used for pentathlon, heptathlon, and decathlon. So they used the Greek prefix tri (three) for the number of events, followed by the already familiar athlon, hence naming the event the Mission Bay Triathlon.

Netflix, currently valued at $150 billion, changed its business model twice by cannibalizing its core services, shifting from mail-in- DVD service to subscription service to streaming video subscription service. This strategic renewal is one of the critical reasons for Netflix to become a valuable company and one of the pioneers in cloud computing that defined the architecture for AWS and set the freedom and responsibility culture for other silicon valley firms to emulate.",

        "evidence": "Spider-Man is a 2002 American superhero film based on the Marvel Comics superhero of the same name. Directed by Sam Raimi from a screenplay by David Koepp, it is the first installment in Raimi's Spider-Man trilogy, and stars Tobey Maguire as the titular character, alongside Willem Dafoe, Kirsten Dunst, James Franco, Cliff Robertson, and Rosemary Harris. The film chronicles Spider-Man's origin story and early superhero career. After being bitten by a genetically-altered spider, outcast teenager Peter Parker develops spider-like superhuman abilities and adopts a masked superhero identity to fight crime and injustice in New York City, facing the sinister Green Goblin (Dafoe) in the process.\n\nDevelopment on a live-action Spider-Man film began in the 1980s. Filmmakers Tobe Hooper, James Cameron, and Joseph Zito were all attached to direct the film at one point. However, the project would languish in development hell due to licensing and financial issues. After progress on the film stalled for nearly 25 years, it was licensed for a worldwide release by Columbia Pictures in 1999 after it acquired options from Metro-Goldwyn-Mayer (MGM) on all previous scripts developed by Cannon Films, Carolco, and New Cannon. Exercising its option on just two elements from the multi-script acquisition (a different screenplay was written by James Cameron, Ted Newsom, John Brancato, Barney Cohen, and Joseph Goldman), Sony hired Koepp to create a working screenplay (credited as Cameron's), and Koepp received sole credit in final billing. Directors Roland Emmerich, Ang Lee, Chris Columbus, Barry Sonnenfeld, Tim Burton, Michael Bay, Jan de Bont, M. Night Shyamalan, Tony Scott, and David Fincher were considered to direct the project before Raimi was hired as director in 2000. The Koepp script was rewritten by Scott Rosenberg during pre-production and received a dialogue polish from Alvin Sargent during production. Filming took place in Los Angeles and New York City from January to June 2001. Sony Pictures Imageworks handled the film's visual effects.",

The digital twin has been intended from its initial introduction to be the underlying premise for Product Lifecycle Management and exists throughout the entire lifecycle (create, build, operate/support, and dispose) of the physical entity it represents. Since information is granular, the digital twin representation is determined by the value-based use cases it is created to implement. The digital twin can and does often exist before there is a physical entity. The use of a digital twin in the create phase allows the intended entity's entire lifecycle to be modeled and simulated. A digital twin of an existing entity can, but must not necessarily, be used in real time and regularly synchronized with the corresponding physical system.Though the concept originated earlier, the first practical definition of a digital twin originated from NASA in an attempt to improve physical-model simulation of spacecraft in 2010.

        "question": "What new transfer learning approach do authors propose for NMT?",
        "answer": "A new transfer approach which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.",

For MultiNLI, we used the dev1-matched set for validation and the dev2-mismatched set for testing.\nTable TABREF28 presents the results of the first experiment. The DL model with GloVe word embeddings achieved better results on three datasets, with 82.80% Accuracy on SNLI, 78.52% Accuracy on MultiNLI, and 83.62% Accuracy on Quora. Logistic Regression achieved the best Accuracy of 98.60% on Clinical-RQE. We also performed a 10-fold cross-validation on the full Clinical-QE data of 8,588 question pairs, which gave 98.61% Accuracy.\nIn the second experiment, we used these datasets for training only and compared their performance on our test set of 850 consumer health questions.

        "evidence": "Natural hydrogen (known as white hydrogen), is naturally occurring molecular hydrogen on or in Earth (as opposed to hydrogen produced in the laboratory or in industry). The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources, and from grey, brown or black hydrogen, which is obtained from fossil sources or from the electrolysis of water. Natural hydrogen may be renewable, non-polluting and allows for lower cost operation compared to industrial hydrogen. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.\n\nOrigin of natural hydrogen\nThere are several sources of natural hydrogen:\n\n- degassing of deep hydrogen from the Earth's crust and mantle;\n- reaction of water with ultrabasic rocks (serpentinisation);\n- contact of water with reducing agents in the Earth's mantle;\n- interaction of water with freshly exposed rock surfaces (weathering);\n- decomposition of hydroxyl ions in the structure of minerals;\n- Natural radiolysis of water;\n- decomposition of organic matter;\n- biological activity\n- Extraction\n- Natural hydrogen is extracted from wells, mixed with other gases such as nitrogen or helium.\n\nSeveral sources have been identified in France. Geologists Alain Prinzhofer and Eric Derville have demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States. However, their potential remains difficult to assess.\n\nNumerous emanations on the ocean floor have been identified but are difficult to exploit. The discovery of a significant emergence in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.\n\nGeology\nNatural hydrogen is generated continuously from a variety of natural sources. There are many known hydrogen emergences on mid-ocean ridges. Another of the known reactions, serpentinisation, occurs under the sea floor (in the oceanic crust).\n\nDiagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably in Russia. Other sources are being explored, such as mantle hydrogen, or hydrogen from radiolysis (natural electrolysis) or from bacterial activity. In France, the Alps and Pyrenees are suitable for exploitation. New Caledonia has hyperalkaline sources that show dihydrogen emissions.

        "evidence": "Table-to-text generation is an important and challenging task in natural language processing, which aims to produce the summarization of numerical table BIBREF0, BIBREF1. The related methods can be empirically divided into two categories, pipeline model and end-to-end model. The former consists of content selection, document planning and realisation, mainly for early industrial applications, such as weather forecasting and medical monitoring, etc. The latter generates text directly from the table through a standard neural encoder-decoder framework to avoid error propagation and has achieved remarkable progress. In this paper, we particularly focus on exploring how to improve the performance of neural methods on table-to-text generation.\nRecently, ROTOWIRE, which provides tables of NBA players' and teams' statistics with a descriptive summary, has drawn increasing attention from academic community. Figure FIGREF1 shows an example of parts of a game's statistics and its corresponding computer generated summary. We can see that the tables has a formal structure including table row header, table column header and table cells. “Al Jefferson” is a table row header that represents a player, “PTS” is a table column header indicating the column contains player's score and “18” is the value of the table cell, that is, Al Jefferson scored 18 points. Several related models have been proposed . They typically encode the table's records separately or as a long sequence and generate a long descriptive summary by a standard Seq2Seq decoder with some modifications. Wiseman explored two types of copy mechanism and found conditional copy model BIBREF3 perform better . Puduppully enhanced content selection ability by explicitly selecting and planning relevant records. Li improved the precision of describing data records in the generated texts by generating a template at first and filling in slots via copy mechanism. Nie utilized results from pre-executed operations to improve the fidelity of generated texts. However, we claim that their encoding of tables as sets of records or a long sequence is not suitable. Because (1) the table consists of multiple players and different types of information as shown in Figure FIGREF1. The earlier encoding approaches only considered the table as sets of records or one dimensional sequence, which would lose the information of other (column) dimension. (2) the table cell consists of time-series data which change over time. That is to say, sometimes historical data can help the model select content. Moreover, when a human writes a basketball report, he will not only focus on the players' outstanding performance in the current match, but also summarize players' performance in recent matches. Lets take Figure FIGREF1 again. Not only do the gold texts mention Al Jefferson's great performance in this match, it also states that “It was the second time in the last three games he's posted a double-double”. Also gold texts summarize John Wall's “double-double” performance in the similar way. Summarizing a player's performance in recent matches requires the modeling of table cell with respect to its historical data (time dimension) which is absent in baseline model. Although baseline model Conditional Copy (CC) tries to summarize it for Gerald Henderson, it clearly produce wrong statements since he didn't get “double-double” in this match.\nTo address the aforementioned problems, we present a hierarchical encoder to simultaneously model row, column and time dimension information. In detail, our model is divided into three layers. The first layer is used to learn the representation of the table cell. Specifically, we employ three self-attention models to obtain three representations of the table cell in its row, column and time dimension. Then, in the second layer, we design a record fusion gate to identify the more important representation from those three dimension and combine them into a dense vector. In the third layer, we use mean pooling method to merge the previously obtained table cell representations in the same row into the representation of the table's row. Then, we use self-attention with content selection gate BIBREF4 to filter unimportant rows' information.

        "question": "What do they want to apply training one model on multiple languages to?",
        "answer": "PropBank-style semantic role labeling.",
        "evidence": "The standard approach to multilingual NLP is to design a single architecture, but tune and train a separate model for each language. While this method allows for customizing the model to the particulars of each language and the available data, it also presents a problem when little data is available: extensive language-specific annotation is required. The reality is that most languages have very little annotated data for most NLP tasks.\nammar2016malopa found that using training data from multiple languages annotated with Universal Dependencies BIBREF1 , and represented using multilingual word vectors, outperformed monolingual training. Inspired by this, we apply the idea of training one model on multiple languages—which we call polyglot training—to PropBank-style semantic role labeling (SRL). We train several parsers for each language in the CoNLL 2009 dataset BIBREF0 : a traditional monolingual version, and variants which additionally incorporate supervision from English portion of the dataset. To our knowledge, this is the first multilingual SRL approach to combine supervision from several languages.\nThe CoNLL 2009 dataset includes seven different languages, allowing study of trends across the same. Unlike the Universal Dependencies dataset, however, the semantic label spaces are entirely language-specific, making our task more challenging. Nonetheless, the success of polyglot training in this setting demonstrates that sharing of statistical strength across languages does not depend on explicit alignment in annotation conventions, and can be done simply through parameter sharing. We show that polyglot training can result in better labeling accuracy than a monolingual parser, especially for low-resource languages. We find that even a simple combination of data is as effective as more complex kinds of polyglot training. We include a breakdown into label categories of the differences between the monolingual and polyglot models. Our findings indicate that polyglot training consistently improves label accuracy for common labels.\nInspired by this, we apply the idea of training one model on multiple languages—which we call polyglot training—to PropBank-style semantic role labeling (SRL).",

        "question": "What are the Variational Auto-Encoders?",
        "answer": "It is a sparse coding based framework called Variational Auto-Encoders (VAEs).",
        "evidence": "The goal of multi-document summarization (MDS) is to automatically generate a brief, well-organized summary for a topic which describes an event with a set of documents from different sources. BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . In the typical setting of MDS, the input is a set of news documents about the same topic. The output summary is a piece of short text document containing several sentences, generated only based on the input original documents.\nWith the development of social media and mobile equipments, more and more user generated content is available. Figure FIGREF2 is a snapshot of reader comments under the news report “The most important announcements from Google's big developers' conference”. The content of the original news report talks about some new products based on AI techniques. The news report generally conveys an enthusiastic tone. However, while some readers share similar enthusiasms, some others express their worries about new products and technologies and these comments can also reflect their interests which may not be very salient in the original news reports. Unfortunately, existing MDS approaches cannot handle this issue. We investigate this problem known as reader-aware multi-document summarization (RA-MDS). Under the RA-MDS setting, one should jointly consider news documents and reader comments when generating the summaries.\nOne challenge of the RA-MDS problem is how to conduct salience estimation by jointly considering the focus of news reports and the reader interests revealed by comments. Meanwhile, the model should be insensitive to the availability of diverse aspects of reader comments. Another challenge is that reader comments are very noisy, not fully grammatical and often expressed in informal expressions. Some previous works explore the effect of comments or social contexts in single document summarization such as blog summarization BIBREF7 , BIBREF8 . However, the problem setting of RA-MDS is more challenging because the considered comments are about an event which is described by multiple documents spanning a time period. Another challenge is that reader comments are very diverse and noisy. Recently, BIBREF9 employed a sparse coding based framework for RA-MDS jointly considering news documents and reader comments via an unsupervised data reconstruction strategy. However, they only used the bag-of-words method to represent texts, which cannot capture the complex relationship between documents and comments.\nRecently, BIBREF6 proposed a sentence salience estimation framework known as VAESum based on a neural generative model called Variational Auto-Encoders (VAEs) BIBREF10 , BIBREF11 . During our investigation, we find that the Gaussian based VAEs have a strong ability to capture the salience information and filter the noise from texts. Intuitively, if we feed both the news sentences and the comment sentences into the VAEs, commonly existed latent aspect information from both of them will be enhanced and become salient. Inspired by this consideration, to address the sentence salience estimation problem for RA-MDS by jointly considering news documents and reader comments, we extend the VAESum framework by training the news sentence latent model and the comment sentence latent model simultaneously by sharing the neural parameters. After estimating the sentence salience, we employ a phrase based compressive unified optimization framework to generate a final summary.\nThere is a lack of high-quality dataset suitable for RA-MDS. Existing datasets from DUC and TAC are not appropriate. Therefore, we introduce a new dataset for RA-MDS. We employed some experts to conduct the tasks of data collection, aspect annotation, and summary writing as well as scrutinizing. To our best knowledge, this is the first dataset for RA-MDS.\nOur contributions are as follows: (1) We investigate the RA-MDS problem and introduce a new dataset for the problem of RA-MDS. To our best knowledge, it is the first dataset for RA-MDS. (2) To tackle the RA-MDS, we extend a VAEs-based MDS framework by jointly considering news documents and reader comments. (3) Experimental results show that reader comments can improve the summarization performance, which also demonstrates the usefulness of the dataset.\nRecently, BIBREF6 proposed a sentence salience estimation framework known as VAESum based on a neural generative model called Variational Auto-Encoders (VAEs).",

You'll soak up a lot just taking the time to really observe.  Second, check-out where the other surfers are entering and where they are swimming out to.  Obvious, I know, but surprisingly people will sometimes skip this step.  Third, see if you can figure out where the channels are - he channel is where the waves are breaking towards.

        "question": "Do the new shift rules in Major League Baseball make the game more exciting?",
        "evidence": "",
        "answer": "Prior to this season, Major League Baseball(MLB) allowed infielders to shift based on who was at bat for the opposing team.  The shift simply means that the defending infield could load a certain side of the infield.  For example, the shortstop could move to where the 2nd baseman normally is positioned and the 2nd baseman might play in shallow right field.  The 3rd baseman would occupy the left side of the infield.  The theory behind this shift strategy is based on advanced analytics used in the game of baseball.  Using a spray chart to determine where a hitter normally puts a ball in play and with what type of pitch thrown, the defending team would shift to cover more of the playing field and therefore increase the chance the defending team would record an out based on this strategy.  \nIt was increasingly used over the last 3-4 years and some argue that employing the shift decreased the number of hits and runs scored during a game.  The downstream effect of this made for a lower scoring affair and a less exciting game for a fan base that is increasingly younger and looking for more excitement during baseball games.  \nOne argument for allowing the shift is that hitters, being professionals, would adjust and try to beat the shift by hitting a ball away from the shift or hitting to the \"opposite field.\"  Hitters answer to beating the shift was to increase their launch angle and play for the home run.  While the home run was an important run scoring mechanism, MLB decided to outlaw the shift from defensive strategy for the 2023 season.  Hitters refusal to adjust to the shift led to this decision by MLB.  The concern was games were not action packed enough and ultimately MLB would continue to lose popularity by its younger viewers, opting for other sports like Basketball, Football, or Hockey to spend their money on.  No longer can you sift defensive players.  The rules for this season are there must be 2 defenders on each side of 2nd base and their feet must be on the infield dirt as the pitch is being delivered.  The hope is more hits will be produced, more runs scored, and an increase in fan approval created.  The early opinion after the first week of the MLB season is that the games are proving to be faster paced with more runs and all around action created.",

        "question": "Given these paragraphs about Large language models, what are some examples of emergent abilities?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

        "evidence": "“Laughter is the best Medicine” is a saying which is popular with most of the people. Humor is a form of communication that bridges the gap between various languages, cultures, ages and demographics. That's why humorous content with funny and witty hashtags are so much popular on social media. It is a very powerful tool to connect with the audience. Automatic Humor Recognition is the task of determining whether a text contains some level of humorous content or not. First conference on Computational humor was organized in 1996, since then many research have been done in this field. kao2016computational does pun detection in one-liners and dehumor detects humor in Yelp reviews. Because of the complex and interesting aspects involved in detecting humor in texts, it is one of the challenging research field in Natural Language Processing BIBREF3 . Identifying humor in a sentence sometimes require a great amount of external knowledge to completely understand it. There are many types of humor, namely anecdotes, fantasy, insult, irony, jokes, quote, self deprecation etc BIBREF4 , BIBREF5 . Most of the times there are different meanings hidden inside a sentence which is grasped differently by individuals, making the task of humor identification difficult, which is why the development of a generalized algorithm to classify different type of humor is a challenging task.\nMajority of the researches on social media texts is focused on English. A study by schroeder2010half shows that, a high percentage of these texts are in non-English languages. fischer2011language gives some interesting information about the languages used on Twitter based on the geographical locations. With a huge amount of such user generated data available on social media, there is a need to develop technologies for non-English languages. In multilingual regions like South Asia, majority of the social media users speak more than two languages. In India, Hindi is the most spoken language (spoken by 41% of the population) and English is the official language of the country. Twitter has around 23.2 million monthly active users in India. Native speakers of Hindi often put English words in the sentences and transliterate the whole sentence to Latin script while posting on social media, thereby making the task of automatic text classification a very challenging problem. Linguists came up with a term for any type of language mixing, known as `code-mixing' or `code-switching' BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . Both the terms are used interchangeably, but there is a slight difference between the two terms. Code-mixing refers to the insertion of words, phrases, and morphemes of one language into a statement or an expression of another language, whereas transliteration of every word in a sentence to another script ( here Devanagari to Latin) is coined code-switching BIBREF10 . The first tweet in Figure 1 is an example of code-mixing and second is an example of code-switching. In this paper, we use code-mixing to denote both cases.\nIn this paper, we present a freely available corpus containing code-mixed tweets in Hindi and English language with tweets written in Latin script. Tweets are manually classified into humorous and non-humorous classes. Moreover, each token in the tweets is also given a language tag which determines the source or origin language of the token (English or Hindi). The paper is divided in sections as follows, we start by describing the corpus and the annotation scheme in Section 2. Section 3 summarizes our supervised classification system which includes pre-processing of the tweets in the dataset and the feature extraction followed by the method used to identify humor in tweets. In the next subsection, we describe the classification model and the results of the experiments conducted using character and word level features. In the last section, we conclude the paper followed by future work and references.\nMoreover, each token in the tweets is also given a language tag which determines the source or origin language of the token (English or Hindi).",

Syntactic patterns BIBREF18 , BIBREF19 , BIBREF20 , BIBREF21 and syntactic dependencies BIBREF3 have been shown to improve performance, while syntactically or semantically important words are often expanding using Wordnet hypernyms or Unified Medical Language System categories (for the medical domain) to help mitigate sparsity BIBREF22 , BIBREF23 , BIBREF24 . Keyword identification helps identify specific terms useful for classification BIBREF25 , BIBREF3 , BIBREF26 .

Here, we empirically demonstrate many of these existing methods do not transfer to the science domain.\nThe highest performing question classification systems tend to make use of customized rule-based pattern matching BIBREF30 , BIBREF7 , or a combination of rule-based and machine learning approaches BIBREF19 , at the expense of increased model construction time. A recent emphasis on learned methods has shown a large set of CNN BIBREF29 and LSTM BIBREF8 variants achieve similar accuracy on TREC question classification, with these models exhibiting at best small gains over simple term frequency models. These recent developments echo the observations of Roberts et al. BIBREF3 , who showed that existing methods beyond term frequency models failed to generalize to medical domain questions. Here we show that strong performance across multiple datasets is possible using a single learned model.\nDue to the cost involved in their construction, question classification datasets and classification taxonomies tend to be small, which can create methodological challenges.

Nonetheless, these are binding contractual agreements. A recent study suggests that up to 98% of users do not fully read the terms of service before accepting them BIBREF0 . Additionally, they find that two of the top three factors users reported for not reading these documents were that they are perceived as too long (`information overload') and too complicated (`difficult to understand'). This can be seen in Table TABREF3 , where a section of the terms of service for a popular phone app includes a 78-word paragraph that can be distilled down to a 19-word summary.\nThe European Union's BIBREF1 , the United States' BIBREF2 , and New York State's BIBREF3 show that many levels of government have recognized the need to make legal information more accessible to non-legal communities. Additionally, due to recent social movements demanding accessible and transparent policies on the use of personal data on the internet BIBREF4 , multiple online communities have formed that are dedicated to manually annotating various unilateral contracts.\nWe propose the task of the automatic summarization of legal documents in plain English for a non-legal audience. We hope that such a technological advancement would enable a greater number of people to enter into everyday contracts with a better understanding of what they are agreeing to. Automatic summarization is often used to reduce information overload, especially in the news domain BIBREF5 . Summarization has been largely missing in the legal genre, with notable exceptions of judicial judgments BIBREF6 , BIBREF7 and case reports BIBREF8 , as well as information extraction on patents BIBREF9 , BIBREF10 . While some companies have conducted proprietary research in the summarization of contracts, this information sits behind a large pay-wall and is geared toward law professionals rather than the general public.\nIn an attempt to motivate advancement in this area, we have collected 446 sets of contract sections and corresponding reference summaries which can be used as a test set for such a task. We have compiled these sets from two websites dedicated to explaining complicated legal documents in plain English.\nRather than attempt to summarize an entire document, these sources summarize each document at the section level. In this way, the reader can reference the more detailed text if need be. The summaries in this dataset are reviewed for quality by the first author, who has 3 years of professional contract drafting experience.\nThe dataset we propose contains 446 sets of parallel text. We show the level of abstraction through the number of novel words in the reference summaries, which is significantly higher than the abstractive single-document summaries created for the shared tasks of the Document Understanding Conference (DUC) in 2002 BIBREF11 , a standard dataset used for single document news summarization. Additionally, we utilize several common readability metrics to show that there is an average of a 6 year reading level difference between the original documents and the reference summaries in our legal dataset.\nIn initial experimentation using this dataset, we employ popular unsupervised extractive summarization models such as TextRank BIBREF12 and Greedy KL BIBREF13 , as well as lead baselines. We show that such methods do not perform well on this dataset when compared to the same methods on DUC 2002. These results highlight the fact that this is a very challenging task. As there is not currently a dataset in this domain large enough for supervised methods, we suggest the use of methods developed for simplification and/or style transfer.\nIn this paper, we begin by discussing how this task relates to the current state of text summarization and similar tasks in Section SECREF2 . We then introduce the novel dataset and provide details on the level of abstraction, compression, and readability in Section SECREF3 .

        "question": "What are the target models?",
        "answer": "LR and MLP.",
        "evidence": "Datasets. We perform our experiments with two predetermined event categories: cyber security (CyberAttack) and death of politicians (PoliticianDeath). These event categories are chosen as they are representative of important event types that are of interest to many governments and companies. The need to create our own dataset was motivated by the lack of public datasets for event detection on microposts. The few available datasets do not suit our requirements. For example, the publicly available Events-2012 Twitter dataset BIBREF20 contains generic event descriptions such as Politics, Sports, Culture etc. Our work targets more specific event categories BIBREF21. Following previous studies BIBREF1, we collect event-related microposts from Twitter using 11 and 8 seed events (see Section SECREF2) for CyberAttack and PoliticianDeath, respectively. Unlabeled microposts are collected by using the keyword `hack' for CyberAttack, while for PoliticianDeath, we use a set of keywords related to `politician' and `death' (such as `bureaucrat', `dead' etc.) For each dataset, we randomly select 500 tweets from the unlabeled subset and manually label them for evaluation. Table TABREF25 shows key statistics from our two datasets.\nComparison Methods. To demonstrate the generality of our approach on different event detection models, we consider Logistic Regression (LR) BIBREF1 and Multilayer Perceptron (MLP) BIBREF2 as the target models. As the goal of our experiments is to demonstrate the effectiveness of our approach as a new model training technique, we use these widely used models. Also, we note that in our case other neural network models with more complex network architectures for event detection, such as the bi-directional LSTM BIBREF17, turn out to be less effective than a simple feedforward network. For both LR and MLP, we evaluate our proposed human-AI loop approach for keyword discovery and expectation estimation by comparing against the weakly supervised learning method proposed by BIBREF1 (BIBREF1) and BIBREF17 (BIBREF17) where only one initial keyword is used with an expectation estimated by an individual expert.\nParameter Settings. We empirically set optimal parameters based on a held-out validation set that contains 20% of the test data. These include the hyperparamters of the target model, those of our proposed probabilistic model, and the parameters used for training the target model. We explore MLP with 1, 2 and 3 hidden layers and apply a grid search in 32, 64, 128, 256, 512 for the dimension of the embeddings and that of the hidden layers. For the coefficient of expectation regularization, we follow BIBREF6 (BIBREF6) and set it to $\\lambda =10 \\times $ #labeled examples. For model training, we use the Adam BIBREF22 optimization algorithm for both models.\nEvaluation. Following BIBREF1 (BIBREF1) and BIBREF3 (BIBREF3), we use accuracy and area under the precision-recall curve (AUC) metrics to measure the performance of our proposed approach. We note that due to the imbalance in our datasets (20% positive microposts in CyberAttack and 27% in PoliticianDeath), accuracy is dominated by negative examples; AUC, in comparison, better characterizes the discriminative power of the model.\nCrowdsourcing. We chose Level 3 workers on the Figure-Eight crowdsourcing platform for our experiments. The inter-annotator agreement in micropost classification is taken into account through the EM algorithm. For keyword discovery, we filter keywords based on the frequency of the keyword being selected by the crowd. In terms of cost-effectiveness, our approach is motivated from the fact that crowdsourced data annotation can be expensive, and is thus designed with minimal crowd involvement. For each iteration, we selected 50 tweets for keyword discovery and 50 tweets for micropost classification per keyword. For a dataset with 80k tweets (e.g., CyberAttack), our approach only requires to manually inspect 800 tweets (for 8 keywords), which is only 1% of the entire dataset.\nTo demonstrate the generality of our approach on different event detection models, we consider Logistic Regression (LR) (Ritter et al. 2015) and Multilayer Perceptron (MLP) (Chambers, Fry, and McMasters 2018) as the target models.",

After being teamless for another 4 months, he joined Newbee in the Summer of 2018.\n\nIn 2018 WCS Montreal, Oliveira reached a new milestone in his SC2 career. He never expected himself to go that deep into the tournament. Oliveira defeated Has 3:2, who was the runner-up of 2018 WCS Valencia, and he advanced to the quarterfinals. In Ro8, he surprised most people by sweeping the series against HeRoMaRinE, one of the best EU Terran players, 3:0. Before him, the Chinese audience had sorely missed one of their own players in the semifinals, the last two being MacSed & Jim in 2013. Even though Reynor ended Oliveira's journey, he had a bright future in the coming years.\n\nOn April 2019, despite losing to MaSa in 2019 WCS Winter AM, Oliveira saw his 4th trip to the Top 8 of a premier tournament.\n\nJust one month after 2019 WCS Winter AM, Oliveira made his breakthrough and stood in front of Serral in the quarterfinals of 2019 WCS Spring. Even though he felt anxious while facing the world's best player, Oliveira still managed to grab one map after an unsuccessful Nydus timing attack from Serral. He said that he had seen the gap between him and the best player and what he could improve in the next tournament after that game.\n\nOn July 2019, Oliveira was defeated by ShoWTimE, the best German Protoss, 1:3 in the quarterfinals of 2019 WCS Summer. Later, he was successfully qualified for Assembly Summer 2019 after defeating Scarlett for the first time. He got revenge against ShoWTimE in Group Stage 2 with two decisive SCV pulls. He then faced Serral in the quarterfinals for the second time and showed his improvement after 3 months' practice. No one expected that Oliveira would almost take down Serral in this BO5, but he narrowly lost 2:3. He even led 2:1 in the series but Serral pulled off a comeback after a vigorous effort and defeated Oliveira with 3:2. During the winner's interview, the reigning WCS Champion said that there was a moment he thought he might have lost the game. Oliveira showed his excellent control just like what ByuN did 3 years ago, and earned himself many fans worldwide.\n\nOn Aug 15, 2019 GSL vs. the World, he dominated one of the best Zerg players from Korea, soO. There was no doubt that Oliveira was now one of the best Terran players in the world.\n\nAfter defeating MaNa 3:1 and Astrea 3:0 in 2019 WCS Fall, Oliveira became the first Mainland Chinese player to qualify for 2019 WCS Global Finals in Anaheim. It had taken 8 years for Chinese fans to see a local player competing in the Global Finals for the first time. No matter the result, Oliveira had initiated a new era for the Chinese StarCraft 2 scene.\n\nWinning IEM Katowice 2023\nIn one of the biggest upsets in Starcraft II history, Oliveira defeated Maru 4:1 in the Grand Final of IEM Katowice 2023 to become the 2023 World Champion.

        "answer": "It gets a 26% gain in precision over the unfiltered baseline, with a slight hit in recall.",
        "evidence": "In Biomedical Information Extraction, Relation Extraction involves finding related entities of many different kinds. Some of these include protein-protein interactions, disease-gene relations and drug-drug interactions. Due to the explosion of available biomedical literature, it is impossible for one person to extract relevant relations from published material. Automatic extraction of relations assists in the process of database creation, by suggesting potentially related entities with links to the source article. For example, a database of drug-drug interactions is important for clinicians who administer multiple drugs simultaneously to their patients- it is imperative to know if one drug will have an adverse effect on the other. A variety of methods have been developed for relation extractions, and are often inspired by Relation Extraction in NLP tasks. These include rule-based approaches, hand-crafted patterns, feature-based and kernel machine learning methods, and more recently deep learning architectures. Relation Extraction systems over Biomedical Corpora are often affected by noisy extraction of entities, due to ambiguities in names of proteins, genes, drugs etc.\n BIBREF12 was one of the first large scale Information Extraction efforts to study the feasibility of extraction of protein-protein interactions (such as “protein A activates protein B\") from Biomedical text. Using 8 hand-crafted regular expressions over a fixed vocabulary, the authors were able to achieve a recall of 30% for interactions present in The Dictionary of Interacting Proteins (DIP) from abstracts in Medline. The method did not differentiate between the type of relation. The reasons for the low recall were the inconsistency in protein nomenclature, information not present in the abstract, and due to specificity of the hand-crafted patterns. On a small subset of extracted relations, they found that about 60% were true interactions between proteins not present in DIP.\n BIBREF13 combine sentence level relation extraction for protein interactions with corpus level statistics. Similar to BIBREF12 , they do not consider the type of interaction between proteins- only whether they interact in the general sense of the word. They also do not differentiate between genes and their protein products (which may share the same name). They use Pointwise Mutual Information (PMI) for corpus level statistics to determine whether a pair of proteins occur together by chance or because they interact. They combine this with a confidence aggregator that takes the maximum of the confidence of the extractor over all extractions for the same protein-pair. The extraction uses a subsequence kernel based on BIBREF14 . The integrated model, that combines PMI with aggregate confidence, gives the best performance. Kernel methods have widely been studied for Relation Extraction in Biomedical Literature. Common kernels used usually exploit linguistic information by utilising kernels based on the dependency tree BIBREF15 , BIBREF16 , BIBREF17 .\n BIBREF18 look at the extraction of diseases and their relevant genes. They use a dictionary from six public databases to annotate genes and diseases in Medline abstracts. In their work, the authors note that when both genes and diseases are correctly identified, they are related in 94% of the cases. The problem then reduces to filtering incorrect matches using the dictionary, which occurs due to false positives resulting from ambiguities in the names as well as ambiguities in abbreviations. To this end, they train a Max-Ent based NER classifier for the task, and get a 26% gain in precision over the unfiltered baseline, with a slight hit in recall. They use POS tags, expanded forms of abbreviations, indicators for Greek letters as well as suffixes and prefixes commonly used in biomedical terms.\n BIBREF19 adopt a supervised feature-based approach for the extraction of drug-drug interaction (DDI) for the DDI-2013 dataset BIBREF20 . They partition the data in subsets depending on the syntactic features, and train a different model for each. They use lexical, syntactic and verb based features on top of shallow parse features, in addition to a hand-crafted list of trigger words to define their features. An SVM classifier is then trained on the feature vectors, with a positive label if the drug pair interacts, and negative otherwise. Their method beats other systems on the DDI-2013 dataset. Some other feature-based approaches are described in BIBREF21 , BIBREF22 .\nDistant supervision methods have also been applied to relation extraction over biomedical corpora. In BIBREF23 , 10,000 neuroscience articles are distantly supervised using information from UMLS Semantic Network to classify brain-gene relations into geneExpression and otherRelation. They use lexical (bag of words, contextual) features as well as syntactic (dependency parse features). They make the “at-least one” assumption, i.e. at least one of the sentences extracted for a given entity-pair contains the relation in database. They model it as a multi-instance learning problem and adopt a graphical model similar to BIBREF24 . They test using manually annotated examples. They note that the F-score achieved are much lesser than that achieved in the general domain in BIBREF24 , and attribute to generally poorer performance of NER tools in the biomedical domain, as well as less training examples. BIBREF25 explore distant supervision methods for protein-protein interaction extraction.\nMore recently, deep learning methods have been applied to relation extraction in the biomedical domain. One of the main advantages of such methods over traditional feature or kernel based learning methods is that they require minimal feature engineering. In BIBREF26 , skip-gram vectors BIBREF27 are trained over 5.6Gb of unlabelled text. They use these vectors to extract protein-protein interactions by converting them into features for entities, context and the entire sentence. Using an SVM for classification, their method is able to outperform many kernel and feature based methods over a variety of datasets.\n BIBREF28 follow a similar method by using word vectors trained on PubMed articles. They use it for the task of relation extraction from clinical text for entities that include problem, treatment and medical test. For a given sentence, given labelled entities, they predict the type of relation exhibited (or None) by the entity pair. These types include “treatment caused medical problem”, “test conducted to investigate medical problem”, “medical problem indicates medical problems”, etc. They use a Convolutional Neural Network (CNN) followed by feedforward neural network architecture for prediction. In addition to pre-trained word vectors as features, for each token they also add features for POS tags, distance from both the entities in the sentence, as well BIO tags for the entities. Their model performs better than a feature based SVM baseline that they train themselves.\nThe BioNLP'16 Shared Tasks has also introduced some Relation Extraction tasks, in particular the BB3-event subtask that involves predicting whether a “lives-in” relation holds for a Bacteria in a location. Some of the top performing models for this task are deep learning models. BIBREF29 train word embeddings with six billions words of scientific texts from PubMed. They then consider the shortest dependency path between the two entities (Bacteria and location). For each token in the path, they use word embedding features, POS type embeddings and dependency type embeddings. They train a unidirectional LSTM BIBREF30 over the dependency path, that achieves an F-Score of 52.1% on the test set.\n BIBREF31 improve the performance by making modifications to the above model. Instead of using the shortest dependency path, they modify the parse tree based on some pruning strategies. They also add feature embeddings for each token to represent the distance from the entities in the shortest path. They then train a Bidirectional LSTM on the path, and obtain an F-Score of 57.1%.\nThe recent success of deep learning models in Biomedical Relation Extraction that require minimal feature engineering is promising. This also suggests new avenues of research in the field. An approach as in BIBREF32 can be used to combine multi-instance learning and distant supervision with a neural architecture.\nTo this end, they train a Max-Ent based NER classifier for the task, and get a 26% gain in precision over the unfiltered baseline, with a slight hit in recall.",

They may protect water supplies, yield wood, harbor wildlife,and provide space to recreate.We are concerned about the level of harvest, the adjacent land use, pollution from nearby industries, or where forests burn. Informed management requires knowledge of all these related factors and, perhaps above all, the spatial arrangement of these factors. Buffer strips near rivers may protect water supplies,clearings may prevent the spread of fire, and polluters upwind may harm our forests. A GIS helps us analyze these spatial interactions, and is also particularly useful at displaying spatial data and analysis. A GIS is often the only way to solve spatially-related problems.",

        "answer": "It combines sequential user click information in a word2vec approach with additional structured information about hotels.",
        "evidence": "Learning semantic representations (embeddings) of different entities, such as textual, commercial, and physical, has been a recent and active area of research. Such representations can facilitate applications that rely on a notion of similarity, for example recommendation systems and ranking algorithms in e-commerce.\nIn natural language processing, word2vec BIBREF0 learns vector representations of words from large quantities of text, where each word is mapped to a $d$-dimensional vector such that semantically similar words have geometrically closer vectors. This is achieved by predicting either the context words appearing in a window around a given target word (skip-gram model), or the target word given the context (CBOW model). The main assumption is that words appearing frequently in similar contexts share statistical properties (the distributional hypothesis). Crucially, word2vec models, like many other word embedding models, preserve sequential information encoded in text so as to leverage word co-occurrence statistics. The skip-gram model has been adapted to other domains in order to learn dense representations of items other than words. For example, product embeddings in e-commerce BIBREF1 or vacation rental embeddings in the hospitality domain BIBREF2 can be learned by treating purchase histories or user click sequences as sentences and applying a word2vec approach.\nMost of the prior work on item embedding exploit the co-occurrence of items in a sequence as the main signal for learning the representation. One disadvantage of this approach is that it fails to incorporate rich structured information associated with the embedded items. For example, in the travel domain, where we seek to embed hotels and other travel-related entities, it could be helpful to encode explicit information such as user ratings, star ratings, hotel amenities, and location in addition to implicit information encoded in the click-stream.\nIn this work, we propose an algorithm for learning hotel embeddings that combines sequential user click information in a word2vec approach with additional structured information about hotels. We propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes. In experimental results, we show that enhancing the neural network to jointly encode click and supplemental structured information outperforms a skip-gram model that encodes the click information alone. The proposed architecture also naturally handles the cold-start problem for hotels with little or no historical clicks. Specifically, we can infer an embedding for these properties by leveraging their supplemental structured metadata.\nCompared to previous work on item embeddings, the novel contributions of this paper are as follows:\nWe propose a novel framework for fusing multiple sources of information about an item (such as user click sequences and item-specific information) to learn item embeddings via self-supervised learning.\nWe generate an interpretable embedding which can be decomposed into sub-embeddings for clicks, location, ratings, and attributes, and employed either as separate component embeddings or a single, unified embedding.\nIt is also dynamic, meaning it is easy to reflect future changes in attributes such as star-rating or addition of amenities in the embedding vectors without retraining.\nWe address the cold-start problem by including hotel metadata which are independent of user click-stream interactions and available for all hotels. This helps us to better impute embeddings for sparse items/hotels.\nWe show significant gains over previous work based on click-embedding in several experimental studies.\nThe structure of the remainder of this paper is as follows. Section 2 gives an overview of some of the recent works on neural embedding. Section 3 provides details of the proposed framework, including the neural network architecture, training methodology, and how the cold-start problem is addressed. In Section 4, we present experimental results on several different tasks and a comparison with previous state-of-the-art work. Section 5 concludes the paper.\nIn this work, we propose an algorithm for learning hotel embeddings that combines sequential user click information in a word2vec approach with additional structured information about hotels.",

The basis of the case was that the Judiciary Act of 1789 allowed for the appointed to request a court order to grant their appointments with original jurisdiction given to the Supreme Court. John Marshall saw that siding with Jefferson would make it seem like the Supreme Court was his lackey.  If they sided with Adams, there was no way to make Jefferson enforce the ruling.  Both decisions would reduce the Supreme Court's legitimacy. John Marshall side-stepped this problem by striking down the Judiciary Act on the grounds that it was unconstitutional.

Although NMT can be significantly better than PBSMT in resource-rich scenarios, PBSMT performs better in low-resource scenarios BIBREF4 . Only by exploiting cross-lingual transfer learning techniques BIBREF5 , BIBREF6 , BIBREF7 , can the NMT performance approach PBSMT performance in low-resource scenarios.\nHowever, such methods usually require an NMT model trained on a resource-rich language pair like French INLINEFORM0 English (parent), which is to be fine-tuned for a low-resource language pair like Uzbek INLINEFORM1 English (child). On the other hand, multilingual approaches BIBREF8 propose to train a single model to translate multiple language pairs. However, these approaches are effective only when the parent target or source language is relatively resource-rich like English (En). Furthermore, the parents and children models should be trained on similar domains; otherwise, one has to take into account an additional problem of domain adaptation BIBREF9 .\nIn this paper, we work on a linguistically distant and thus challenging language pair Japanese INLINEFORM0 Russian (Ja INLINEFORM1 Ru) which has only 12k lines of news domain parallel corpus and hence is extremely resource-poor. Furthermore, the amount of indirect in-domain parallel corpora, i.e., Ja INLINEFORM2 En and Ru INLINEFORM3 En, are also small.

To that end, we built a recurrent neural network model in the language that had largest data available. We took a general-to-specific model building strategy where the larger corpus that had reviews from different domains was first used to train the RNN model and a smaller single-domain corpus of sentiment reviews was used to specialize the model on the given domain.

We remark, for the sake of clarity, that our test design is slightly different from the traditional testing approaches used by BIBREF10 , BIBREF9 , BIBREF12 , since we do not consider the shortest sequence in a language whose output was incorrectly predicted by the model, or the largest accepted test set, or the accuracy of the model on a fixed test set.\nIt has been shown by BIBREF9 that LSTMs can learn $a^n b^n$ and $a^n b^n c^n$ with 1 and 2 hidden units, respectively. Similarly, BIBREF24 demonstrated that a simple RNN architecture containing a single hidden unit with carefully tuned parameters can develop a canonical linear counting mechanism to recognize the simple context-free language $a^n b^n$ , for $n \\le 250$ . We wanted to explore whether the stability of the networks would improve with an increase in capacity of the LSTM model. We, therefore, varied the number of hidden units in our LSTM models as follows.

        "evidence": "Habiganj Bazar–Shaistaganj–Balla line During the colonial British rule, train services were started by rail at Habiganj Mahukuma in Sylhet district of the then (Undivided British-India) Assam province. In 1928, the British government built the Habiganj Bazar-Shaistaganj-Balla line as railway line and built infrastructure.\n\nThe railway line was opened by the Assam Bengal Railway by the then British government from Habiganj district headquarters town to Balla border via Shaistaganj junction, about 45 or 52 kilometers long railway line.\n\nOf these, the Shaistaganj-Habiganj (15 or 16 km) railway line was inaugurated in 1928 and the Shaistaganj-Balla (30 or 36 km) railway line was inaugurated in 1929. \n\nCoal-engined trains used to run between eight stations at Habiganj Bazar, Habiganj Court, Shaistaganj Junction, Shakir Mohammad, Chunarughat, Amuroad, Assampara and Balla bordering Tripura.\n\nOf these, Chunarughat, Amur road and Assampara stations were of great importance. Tea produced in 22 tea gardens from those three stations was transported by rail.\n\nAt that time, this railway was the only means of exporting tea leaves of 13 gardens of Chunarughat upazila of Habiganj at a low cost and importing related items including garden rations.\n\nThere are a total of 4 stations on the Shaistaganj-Habiganj railway line (excluding Shaistaganj Junction), namely: Habiganj Bazar, Habiganj Court, Dhuliakhal and Paikpara. The Shaistaganj-Balla railway line has a total of 7 stations (excluding Shaistaganj Junction), namely: Barkula, Shakir Muhammed, Sutang Bazar, Chunarughat, Amu Road, Assampara and Balla.\n\nAfter the independence of Bangladesh, the importance of the Balla train increased further. For this reason, the railway authorities built two more stations named Sutang Bazar and Barkula, known as remote areas.\n\nAt that time, the role of the train in bringing back refugees from India was commendable. At that time, a diesel engine was added to the ballar train. The train used to travel twice a day from Habiganj to the border station Balla.\n\nAfter the end of the refugee transportation phase, the smugglers took over the train in Balla. Later, the train of Balla became a train of smugglers. At first, the passengers protested about this, but later the passengers got the opportunity to travel without a ticket.\n\nIn such a situation, the running train suffered losses. The railway authorities suspended the renovation work of the railway line.",

        "evidence": "Knowledge sharing platforms such as Quora and Zhihu emerge as very convenient tools for acquiring knowledge. These question and answer (Q&A) platforms are newly emerged communities about knowledge acquisition, experience sharing and social networks services (SNS).\nUnlike many other Q&A platforms, Zhihu platform resembles a social network community. Users can follow other people, post ideas, up-vote or down-vote answers, and write their own answers. Zhihu allows users to keep track of specific fields by following related topics, such as “Education”, “Movie”, “Technology” and “Music”. Once a Zhihu user starts to follow a specific topic or a person, the related updates are automatically pushed to the user's feed timeline.\nAlthough these platforms have exploded in popularity, they face some potential problems. The key problem is that as the number of users grows, a large volume of low-quality questions and answers emerge and overwhelm users, which make users hard to find relevant and helpful information.\nZhihu Live is a real-time voice-answering product on the Zhihu platform, which enables the speakers to share knowledge, experience, and opinions on a subject. The audience can ask questions and get answers from the speakers as well. It allows communication with the speakers easily and efficiently through the Internet. Zhihu Live provides an extremely useful reward mechanism (like up-votes, following growth and economic returns), to encourage high-quality content providers to generate high-level information on Zhihu platform.\nHowever, due to the lack of efficient filter mechanism and evaluation schemes, many users suffer from lots of low-quality contents, which affects the service negatively. Recently, studies on social Q&A platforms and knowledge sharing are rising and have achieved many promising results. Shah et al. BIBREF0 propose a data-driven approach with logistic regression and carefully designed hand-crafted features to predict the answer quality on Yahoo! Answers. Wang et al. BIBREF1 illustrate that heterogeneity in the user and question graphs are important contributors to the quality of Quora's knowledge base. Paul et al. BIBREF2 explore reputation mechanism in quora through detailed data analysis, their experiments indicate that social voting helps users identify and promote good content but is prone to preferential attachment. Patil et al. BIBREF3 propose a method to detect experts on Quora by their activity, quality of answers, linguistic characteristics and temporal behaviors, and achieves 97% accuracy and 0.987 AUC. Rughinis et al. BIBREF4 indicate that there are different regimes of engagement at the intersection of the technological infrastructure and users' participation in Quora.\nAll of these works are mainly focused on answer ranking and answer quality evaluation. But there is little research achievement about quality evaluation in voice-answering areas. In this work, we present a data-driven approach for quality evaluation about Zhihu Live, by consuming the dataset we collected to gather knowledge and insightful conclusion. The proposed data-driven approach includes data collection, storage, preprocessing, data analysis, and predictive analysis via machine learning. The architecture of our data-driven method is shown in Fig. FIGREF3 . The records are crawled from Zhihu Live official website and stored in MongoDB. Data preprocessing methods include cleaning and data normalization to make the dataset satisfy our target problem. Descriptive data analysis and predictive analysis are also conducted for deeper analysis about this dataset.\nThe main contributions of this paper are as follows: (1) We release a public benchmark dataset which contains 7242 records and 286,938 text comments about Zhihu Live. Detailed analysis about the dataset is also discussed in this paper. This dataset could help researchers verify their ideas in related fields. (2) By analyzing this dataset, we gain several insightful conclusion about Zhihu Live. (3) We also propose a multi-branched neural network (MTNet) to evaluate Zhihu Lives' scores. The superiority of our proposed model is demonstrated by comparing performance with other mainstream regressors.\nThe rest of this paper is organized as follows: Section 2 describes detailed procedures of ZhihuLive-DB collection, and descriptive analysis. Section 3 illustrates our proposed MTNet. In section 4, we give a detailed description of experiments, and the last section discusses the conclusion of this paper and future work.\nPatil et al.

Parts B and C focus on the proposed methods where part B contains methods using neural networks only, while part C uses average of word embeddings learned by DNNs as features for GBDTs. We experimented with multiple classifiers but report results mostly for GBDTs only, due to lack of space.\nAs the table shows, our proposed methods in part B are significantly better than the baseline methods in part A. Among the baseline methods, the word TF-IDF method is better than the character n-gram method. Among part B methods, CNN performed better than LSTM which was better than FastText. Surprisingly, initialization with random embeddings is slightly better than initialization with GloVe embeddings when used along with GBDT. Finally, part C methods are better than part B methods. The best method is “LSTM + Random Embedding + GBDT” where tweet embeddings were initialized to random vectors, LSTM was trained using back-propagation, and then learned embeddings were used to train a GBDT classifier. Combinations of CNN, LSTM, FastText embeddings as features for GBDTs did not lead to better results. Also note that the standard deviation for all these methods varies from 0.01 to 0.025.\nTo verify the task-specific nature of the embeddings, we show top few similar words for a few chosen words in Table TABREF7 using the original GloVe embeddings and also embeddings learned using DNNs. The similar words obtained using deep neural network learned embeddings clearly show the “hatred” towards the target words, which is in general not visible at all in similar words obtained using GloVe.\nThe best method is “LSTM + Random Embedding + GBDT” where tweet embeddings were initialized to random vectors, LSTM was trained using back-propagation, and then learned embeddings were used to train a GBDT classifier.",

        "answer": "A novel method to provide strong word sense disambiguation when translating wordnet entries into several different European languages.",
        "evidence": "Princeton WordNet BIBREF0 is one of the most important resources used in many different tasks across linguistics and natural language processing, however the resource is only available for English and is limited in its coverage of real world concepts. To cross the language barrier, huge efforts have been made to extend the Princeton WordNet with multilingual information in projects, such as EuroWordNet BIBREF1 , BalkaNet BIBREF2 and MultiWordNet BIBREF3 , mostly following the extend approach, where the structure of the Princeton WordNet is preserved and only the words in each synset are translated and new synsets are added for concepts. Furthermore, the Princeton WordNet has many fewer concepts than large scale encyclopedias such as Wikipedia and resources derived from it such as DBpedia BIBREF4 and BabelNet BIBREF5 . This problem is even worse for many non-English wordnets, due to the extend approach, as these resources have even fewer synsets than Princeton WordNet. Furthermore, there are still many languages for which a wordnet does not exist or is not available to all potential users due to licensing restrictions.\nTo address these deficiencies we propose two approaches. Firstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages. While an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries. In addition, our method can handle fundamental complexities such as the need to translate all senses of a word including low-frequency senses, which is very challenging for current SMT approaches. For these reasons, we leverage existing translations of Princeton WordNet entries in other languages to identify contextual information for wordnet senses from a large set of generic parallel corpora. The goal is to identify sentences that share the same semantic information in respect to the synset of the Princeton WordNet entry that we want to translate. Secondly, we describe a novel system based on state-of-the-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia. This method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks. These statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph. These are combined using a constraint-based solver that considers not only the semantic similarity of the synsets but also the overall structure of the alignment and its consistency, following the best practices in ontology alignment.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet BIBREF6 , which is available under an open (CC-BY) license. Finally, we describe how this resource is published, firstly as linked data in the linguistic linked open data cloud, as well as published in all the formats of the Global WordNet Association Interlingual Index.\nWhile an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries.",

        "evidence": "It is well known that language has certain structural properties which allows natural language speakers to make “infinite use of finite means\" BIBREF3 . This structure allows us to generalize beyond the typical machine learning definition of generalization BIBREF4 (which considers performance on the distribution that generated the training set), permitting the understanding of any utterance sharing the same structure, regardless of probability. For example, sentences of length 100 typically do not appear in natural text or speech (our personal 'training set'), but can be understood regardless due to their structure. We refer to this notion as linguistic generalization .\nMany problems in NLP are treated as sequence to sequence tasks with solutions built on seq2seq-attention based models. While these models perform very well on standard datasets and also appear to capture some linguistic structure BIBREF5 , BIBREF6 , BIBREF7 , they also can be quite brittle, typically breaking on uncharacteristic inputs BIBREF8 , BIBREF1 , indicating that the extent of linguistic generalization these models achieve is still somewhat lacking.\nDue to the high capacity of these models, it is not unreasonable to expect them to learn some structure from the data. However, learning structure is not a sufficient condition to achieving linguistic generalization. If this structure is to be usable on data outside the training distribution, the model must learn the structure without additionally learning (overfitting on) patterns specific to the training data. One may hope, given the right hyperparameter configuration and regularization, that a model converges to a solution that captures the reusable structure without overfitting too much on the training set. While this solution exists in theory, in practice, it may be difficult to find.\nIn this work, we look at the feasibility of training and tuning seq2seq-attention models towards a solution that generalizes in this linguistic sense. In particular, we train models on a symbol replacement task with a well defined generalizable structure. The task is simple enough that all models achieve near perfect accuracy on the standard test set, i.e., where the inputs are drawn from the same distribution as that of the training set. We then test these models for linguistic generalization by creating test sets of uncharacteristic inputs, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned. Our results indicate that generalization is highly sensitive; such that even changes in the random seed can drastically affect the ability to generalize. This dependence on an element that is not (or ideally should not be) a hyperparameter suggests that the line between generalization and failure is quite fine, and may not be feasible to reach simply by hyperparameter tuning alone.\nOur results indicate that generalization is highly sensitive; such that even changes in the random seed can drastically affect the ability to generalize.",

The toe loop is a pick assisted jump, meaning that one leg will stick a toe pick into the ice to help with the jump. In the case of a toe loop, you will enter on your right outside edge and rotate your left free leg behind you to pick the ice. It's important that the free leg is twisted as far back and sideways as possible to add stability. \n\nYou'll then want to jump when your skating foot approaches your pick foot and complete a single rotation in the air. Bringing the arms together and having proper posture will help with completing the rotation. Then, you will want to land on your right leg on a backwards outside edge.

        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations.",

These content creators are known as reactors. There are multiple reasons people might like them. Most commonly, people want to know how others feel about something they love. As social animals, human beings like being able to share experiences with others. Watching people have similar reactions to theirs validates their own lived experiences. Reaction channels can also serve as a way to get a review of media, food etc. without having to go out and try it for yourself which often requires an investment of time or money or both. In case you already agree with the reactors on other items, these reviews can prove to be more trustworthy than seeing an arbitrary written review somewhere on the internet and might open the viewer up to new experiences. These channels also gained a lot of popularity during COVID lockdowns between 2020-2021 because a lot of people were isolated and being able to share things they loved with others online helped build a sense of virtual community and helped people feel less alone.",

        "question": "From the provided description of the cheesemaking process, list the ingredients required to make cheese.",
        "evidence": "The goal of cheese making is to control the spoiling of milk into cheese. The milk is traditionally from a cow, goat, sheep or buffalo, although, in theory, cheese could be made from the milk of any mammal. Cow's milk is most commonly used worldwide. The cheesemaker's goal is a consistent product with specific characteristics (appearance, aroma, taste, texture). The process used to make a Camembert will be similar to, but not quite the same as, that used to make Cheddar.\n\nSome cheeses may be deliberately left to ferment from naturally airborne spores and bacteria; this approach generally leads to a less consistent product but one that is valuable in a niche market.\n\nCulturing\nCheese is made by bringing milk (possibly pasteurised) in the cheese vat to a temperature required to promote the growth of the bacteria that feed on lactose and thus ferment the lactose into lactic acid. These bacteria in the milk may be wild, as is the case with unpasteurised milk, added from a culture, frozen or freeze dried concentrate of starter bacteria. Bacteria which produce only lactic acid during fermentation are homofermentative; those that also produce lactic acid and other compounds such as carbon dioxide, alcohol, aldehydes and ketones are heterofermentative. Fermentation using homofermentative bacteria is important in the production of cheeses such as Cheddar, where a clean, acid flavour is required. For cheeses such as Emmental the use of heterofermentative bacteria is necessary to produce the compounds that give characteristic fruity flavours and, importantly, the gas that results in the formation of bubbles in the cheese ('eye holes').\n\nStarter cultures are chosen to give a cheese its specific characteristics. In the case of mould-ripened cheese such as Stilton, Roquefort or Camembert, mould spores (fungal spores) may be added to the milk in the cheese vat or can be added later to the cheese curd.\n\nCoagulation\nDuring the fermentation process, once sufficient lactic acid has been developed, rennet is added to cause the casein to precipitate. Rennet contains the enzyme chymosin which converts κ-casein to para-κ-caseinate (the main component of cheese curd, which is a salt of one fragment of the casein) and glycomacropeptide, which is lost in the cheese whey. As the curd is formed, milk fat is trapped in a casein matrix. After adding the rennet, the cheese milk is left to form curds over a period of time.\n\n\nFresh chevre hanging in cheesecloth to drain.\nDraining\nOnce the cheese curd is judged to be ready, the cheese whey must be released. As with many foods the presence of water and the bacteria in it encourages decomposition. To prevent such decomposition it is necessary to remove most of the water (whey) from the cheese milk, and hence cheese curd, to make a partial dehydration of the curd. There are several ways to separate the curd from the whey.\n\n\nMaturing cheese in a cheese cellar\nScalding\nIn making Cheddar (or many other hard cheeses) the curd is cut into small cubes and the temperature is raised to approximately 39 °C (102 °F) to 'scald' the curd particles. Syneresis occurs and cheese whey is expressed from the particles. The Cheddar curds and whey are often transferred from the cheese vat to a cooling table which contains screens that allow the whey to drain, but which trap the curd. The curd is cut using long, blunt knives and 'blocked' (stacked, cut and turned) by the cheesemaker to promote the release of cheese whey in a process known as 'cheddaring'. During this process the acidity of the curd increases to a desired level. The curd is then milled into ribbon shaped pieces and salt is mixed into it to arrest acid development. The salted green cheese curd is put into cheese moulds lined with cheesecloths and pressed overnight to allow the curd particles to bind together. The pressed blocks of cheese are then removed from the cheese moulds and are either bound with muslin-like cloth, or waxed or vacuum packed in plastic bags to be stored for maturation. Vacuum packing removes oxygen and prevents mould (fungal) growth during maturation, which depending on the wanted final product may be a desirable characteristic or not.\n\nMould-ripening\nMain article: Cheese ripening\nIn contrast to cheddaring, making cheeses like Camembert requires a more gentle treatment of the curd. It is carefully transferred to cheese hoops and the whey is allowed to drain from the curd by gravity, generally overnight. The cheese curds are then removed from the hoops to be brined by immersion in a saturated salt solution. The salt absorption stops bacteria growing, as with Cheddar. If white mould spores have not been added to the cheese milk it is applied to the cheese either by spraying the cheese with a suspension of mould spores in water or by immersing the cheese in a bath containing spores of, e.g., Penicillium candida.\n\nBy taking the cheese through a series of maturation stages where temperature and relative humidity are carefully controlled, allowing the surface mould to grow and the mould-ripening of the cheese by fungi to occur. Mould-ripened cheeses ripen very quickly compared to hard cheeses (weeks against months or years). This is because the fungi used are biochemically very active when compared with starter bacteria. Some cheeses are surface-ripened by moulds, such as Camembert and Brie, some are ripened internally, such as Stilton, which is pierced with stainless steel wires, to admit air to promote mould spore germination and growth, as with Penicillium roqueforti. Surface ripening of some cheeses, such as Saint-Nectaire, may also be influenced by yeasts which contribute flavour and coat texture. Others are allowed to develop bacterial surface growths which give characteristic colours and appearances, e.g. by the growth of Brevibacterium linens which gives an orange coat to cheeses.",
        "answer": "The main ingredient used to make cheese is milk. Cow's milk is commonly used, though goat, sheep or buffalo can also be used, as could the milk of any mammal in theory. Starter cultures are typically added to aid in the culturing stage of the process. Rennet is added to the cheese milk to promote the separation into cheese curd and whey. Ultimately, salt is added to halt the production of acid later in the process. Finally, mould spores are introduced to assist in ripening. This can be added to the cheese milk early on in the process, or just prior to maturing.",

        "evidence": "Ambiguity and implicitness are inherent properties of natural language that cause challenges for computational models of language understanding. In everyday communication, people assume a shared common ground which forms a basis for efficiently resolving ambiguities and for inferring implicit information. Thus, recoverable information is often left unmentioned or underspecified. Such information may include encyclopedic and commonsense knowledge. This work focuses on commonsense knowledge about everyday activities, so-called scripts.\nThis paper introduces a dataset to evaluate natural language understanding approaches with a focus on interpretation processes requiring inference based on commonsense knowledge. In particular, we present MCScript, a dataset for assessing the contribution of script knowledge to machine comprehension. Scripts are sequences of events describing stereotypical human activities (also called scenarios), for example baking a cake or taking a bus BIBREF0 . To illustrate the importance of script knowledge, consider Example ( SECREF1 ):\nWithout using commonsense knowledge, it may be difficult to tell who ate the food: Rachel or the waitress. In contrast, if we utilize commonsense knowledge, in particular, script knowledge about the eating in a restaurant scenario, we can make the following inferences: Rachel is most likely a customer, since she received an order. It is usually the customer, and not the waitress, who eats the ordered food. So She most likely refers to Rachel.\nVarious approaches for script knowledge extraction and processing have been proposed in recent years. However, systems have been evaluated for specific aspects of script knowledge only, such as event ordering BIBREF1 , BIBREF2 , event paraphrasing BIBREF3 , BIBREF4 or event prediction (namely, the narrative cloze task BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 ). These evaluation methods lack a clear connection to real-world tasks. Our MCScript dataset provides an extrinsic evaluation framework, based on text comprehension involving commonsense knowledge. This framework makes it possible to assess system performance in a multiple-choice question answering setting, without imposing any specific structural or methodical requirements.\nMCScript is a collection of (1) narrative texts, (2) questions of various types referring to these texts, and (3) pairs of answer candidates for each question.

Answering a substantial subset of questions requires knowledge beyond the facts mentioned in the text, i.e. it requires inference using commonsense knowledge about everyday activities. An example is given in Figure FIGREF2 . For both questions, the correct choice for an answer requires commonsense knowledge about the activity of planting a tree, which goes beyond what is mentioned in the text. Texts, questions, and answers were obtained through crowdsourcing. In order to ensure high quality, we manually validated and filtered the dataset. Due to our design of the data acquisition process, we ended up with a substantial subset of questions that require commonsense inference (27.4%).\nOur MCScript dataset provides an extrinsic evaluation framework, based on text comprehension involving commonsense knowledge.

The videos are collected and used in a manner compatible with national regulations on usage of data for research. Unlike most curated video datasets, this data is more representative of the types of videos shared \"in the wild\", containing a large proportion of videogames, screenshots and memes.\nUsing a classifier trained on a small amount of labelled data, we estimate that videogame footage makes up 25% of examples, other screenshots, memes and comics make up 24%, live action footage is 49% and artistic styled content (such as drawn animation) is 2%. The average video length is 33s.\nFrom 1 million raw videos collected, we perform deduplication and filtering, ending up with a training set of 461k videos, and validation and test sets of 66k videos each. For the video evaluation results in Table, we use a subset of the test set, consisting of 5000 videos with at least three comments each. In addition to comments, for one experiment in Table we also obtain textual labels of objects in the video thumbnails, using the Google Vision API. We obtain labels for 10,212 different classes, from \"Abacus\" to \"Zwiebelkuchen\". This serves as a useful comparison, giving textual metadata that can be expected to be more directly related to the visual video contents than user comments, and can be seen as a proxy for user-generated \"hashtags\". It also illustrates how, by using text as an intermediary, we can integrate predictions from any black-box classifier in the same framework.\nKineticsComments. As an additional video dataset with comments, we construct a dataset based on Kinetics-700, for which we download the videos along with associated YouTube metadata including title, description and comments. We translate non-English titles and descriptions into English using a commercial translation API. We use the title as the primary text modality, and for auxiliary context we use comments and (when training) sentences from the description.

It was used alongside the panokseon warships in the fight against invading Japanese naval ships. The ship's name derives from its protective shell-like covering. One of a number of pre-industrial armored ships developed in Europe and in East Asia, this design has been described by some as the first armored ship in the world.\n\nThe first references to older, first-generation turtle ships, known as gwiseon (귀선;  Korean pronunciation: [kɥisʌn]), come from 1413 and 1415 records in the Annals of the Joseon Dynasty, which mention a mock battle between a gwiseon and a Japanese warship. However, these early turtle ships soon fell out of use as Korea's naval preparedness decreased during a long period of relative peace. \n\nTurtle ships participated in the war against Japanese naval forces supporting Toyotomi Hideyoshi's attempts to conquer Korea from 1592 to 1598.  Korean Admiral Yi Sun-sin, who won all battles against the Japanese Navy, is credited with designing the improved turtle ship. From their first appearance in the Battle of Sacheon, his turtle ships, equipped with at least five different types of cannon, greatly contributed to winning 16 times in 16 battles against the Japanese Navy until they were destroyed, under the command of Won Gyun, in the Battle of Chilcheollyang. Their most distinguishable feature was a dragon-shaped head at the bow (front) that could launch cannon fire or flames from the mouth. Each was also equipped with a fully covered deck to protect against arrow fire, musket-shots, and incendiary weapons.  The deck was covered with iron spikes to discourage the enemy from attempting to board the ship.",

        "evidence": "Natural Language Generation (NLG) plays a critical role in Spoken Dialogue Systems (SDS) with task is to convert a meaning representation produced by the Dialogue Manager into natural language utterances. Conventional approaches still rely on comprehensive hand-tuning templates and rules requiring expert knowledge of linguistic representation, including rule-based BIBREF0 , corpus-based n-gram models BIBREF1 , and a trainable generator BIBREF2 .\nRecently, Recurrent Neural Networks (RNNs) based approaches have shown promising performance in tackling the NLG problems. The RNN-based models have been applied for NLG as a joint training model BIBREF3 , BIBREF4 and an end-to-end training model BIBREF5 . A recurring problem in such systems is requiring annotated datasets for particular dialogue acts (DAs). To ensure that the generated utterance representing the intended meaning of the given DA, the previous RNN-based models were further conditioned on a 1-hot vector representation of the DA. BIBREF3 introduced a heuristic gate to ensure that all the slot-value pair was accurately captured during generation. BIBREF4 subsequently proposed a Semantically Conditioned Long Short-term Memory generator (SC-LSTM) which jointly learned the DA gating signal and language model.\nMore recently, Encoder-Decoder networks BIBREF6 , BIBREF7 , especially the attentional based models BIBREF8 , BIBREF9 have been explored to solve the NLG tasks. The Attentional RNN Encoder-Decoder BIBREF10 (ARED) based approaches have also shown improved performance on a variety of tasks, e.g., image captioning BIBREF11 , BIBREF12 , text summarization BIBREF13 , BIBREF14 .\nWhile the RNN-based generators with DA gating-vector can prevent the undesirable semantic repetitions, the ARED-based generators show signs of better adapting to a new domain. However, none of the models show significant advantage from out-of-domain data. To better analyze model generalization to an unseen, new domain as well as model leveraging the out-of-domain sources, we propose a new architecture which is an extension of the ARED model. In order to better select, aggregate and control the semantic information, a Refinement Adjustment LSTM-based component (RALSTM) is introduced to the decoder side. The proposed model can learn from unaligned data by jointly training the sentence planning and surface realization to produce natural language sentences. We conducted experiments on four different NLG domains and found that the proposed methods significantly outperformed the state-of-the-art methods regarding BLEU BIBREF15 and slot error rate ERR scores BIBREF4 .

        "question": "What was “fusion” referred to by FusionNet?",
        "answer": "The process of updating the representation of passage (or question) using information from the question (or passage) representation.",
        "evidence": "The goal of Machine Reading Comprehension (MRC) is to have machines read a text passage and then generate an answer (or select an answer from a list of given candidates) for any question about the passage. There has been a growing interest in the research community in exploring neural MRC models in an end-to-end fashion, thanks to the availability of large-scale datasets, such as CNN/DM BIBREF0 and SQuAD BIBREF1 .\nDespite the variation in model structures, most state-of-the-art models perform reading comprehension in two stages. First, the symbolic representations of passages and questions are mapped into vectors in a neural space. This is commonly achieved via embedding and attention BIBREF2 , BIBREF3 or fusion BIBREF4 . Then, reasoning is performed on the vectors to generate the right answer.\nIdeally, the best attention and reasoning strategies should adapt organically in order to answer different questions. However, most MRC models use a static attention and reasoning strategy indiscriminately, regardless of various question types. One hypothesis is because these models are optimized on those datasets whose passages and questions are domain-specific (or of a single type). For example, in CNN/DM, all the passages are news articles, and the answer to each question is an entity in the passage. In SQuAD, the passages came from Wikipedia articles and the answer to each question is a text span in the article. Such a fixed-strategy MRC model does not adapt well to other datasets. For example, the exact-match score of BiDAF BIBREF2 , one of the best models on SQuAD, drops from 81.5 to 55.8 when applied to TriviaQA BIBREF5 , whereas human performance is 82.3 and 79.7 on SQuAD and TriviaQA, respectively.\nIn real-world MRC tasks, we must deal with questions and passages of different types and complexities, which calls for models that can dynamically determine what attention and reasoning strategy to use for any input question-passage pair on the fly. In a recent paper, BIBREF6 proposed dynamic multi-step reasoning, where the number of reasoning steps is determined spontaneously (using reinforcement learning) based on the complexity of the input question and passage. With a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.\nThe proposed model is called a Dynamic Fusion Network (DFN). In this paper, we describe the version of DFN developed on the RACE dataset BIBREF7 . In RACE, a list of candidate answers is provided for each passage-question pair. So DFN for RACE is a scoring model - the answer candidate with the highest score will be selected as the final answer.\nLike other MRC models, DFNs also perform machine reading in two stages: attention and reasoning. DFN is unique in its use of a dynamic multi-strategy attention process in the attention stage. Here “attention” refers to the process that texts from different sources (passage, question, answers) are combined in the network. In literature, a fixed attention mechanism is usually employed in MRC models. In DFN, the attention strategy is not static; instead, the actual strategy for drawing attention among the three text sources are chosen on the fly for each sample. This lends flexibility to adapt to various question types that require different comprehension skills. The output of the attention stage is then fed into the reasoning module to generate the answer score. The reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.\nInspired by ReasoNet BIBREF6 and dynamic neural module networks BIBREF8 , we use deep reinforcement learning methods BIBREF9 , BIBREF10 to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample. We use RL in favor of other simpler methods (like cascading, pooling or weighted averaging) mainly because we intend to learn a policy that constructs an instance of DFN of a sample-specific structure. Given an input sample consisting of a question, a passage and a list of candidate answers in RACE, an instance of DFN can be constructed via RL step by step on the fly. Such a policy is particularly appealing as it also provides insights on how the model performs on different types of questions. At each decision step, the policy maps its “state”, which represents an input sample, and DFN's partial knowledge of the right answer, to the action of assembling proper attention and reasoning modules for DFN.\nExperiments conducted on the RACE dataset show that DFN significantly outperforms previous state-of-the-art MRC models and has achieved the best result reported on RACE. A thorough empirical analysis also demonstrates that DFN is highly effective in understanding passages of a wide variety of styles and answering questions of different complexities.\nThe word “fusion” for MRC was first used by FusionNet (Huang et al., 2017) to refer to the process of updating the representation of passage (or question) using information from the question (or passage) representation.",

        "evidence": "Contrastive evaluation is different from conventional evaluation of machine translation in that it does not require any translation. Rather than testing a model's ability to translate, it is a method to test a model's ability to discriminate between given good and bad translations.\nWe exploit the fact that NMT systems are in fact language models of the target language, conditioned on source text. Like language models, NMT systems can be used to compute a model score (the negative log probability) for an existing translation. Contrastive evaluation, then, means to compare the model score of two pairs of inputs: INLINEFORM0 and INLINEFORM1 . If the model score of the actual reference translation is higher, we assume that this model can detect wrong pronoun translations.\nHowever, this does not mean that systems actually produce the reference translation when given the source sentence for translation. An entirely different target sequence might rank higher in the system's beam during decoding. The only conclusion permitted by contrastive evaluation is whether or not the reference translation is more probable than a contrastive variant.\nIf the model score of the reference is indeed higher, we refer to this outcome as a “correct decision” by the model. The model's decision is only correct if the reference translation has a higher score than any contrastive translation. In our evaluation, we aggregate model decisions on the whole test set and report the overall percentage of correct decisions as accuracy.\nDuring scoring, the model is provided with reference translations as target context, while during translation, the model needs to predict the full sequence. It is an open question to what extent performance deteriorates when context is itself predicted, and thus noisy. We highlight that the same problem arises for sentence-level NMT, and has been addressed with alternative training strategies BIBREF27 .\nRather than testing a model’s ability to translate, it is a method to test a model’s ability to discriminate between given good and bad translations.",

        "question": "What is one of the main advantages of deep learning methods over traditional feature or kernel based learning methods?",
        "answer": "The deep learning methods require minimal feature engineering.",
        "evidence": "In Biomedical Information Extraction, Relation Extraction involves finding related entities of many different kinds. Some of these include protein-protein interactions, disease-gene relations and drug-drug interactions. Due to the explosion of available biomedical literature, it is impossible for one person to extract relevant relations from published material. Automatic extraction of relations assists in the process of database creation, by suggesting potentially related entities with links to the source article. For example, a database of drug-drug interactions is important for clinicians who administer multiple drugs simultaneously to their patients- it is imperative to know if one drug will have an adverse effect on the other. A variety of methods have been developed for relation extractions, and are often inspired by Relation Extraction in NLP tasks. These include rule-based approaches, hand-crafted patterns, feature-based and kernel machine learning methods, and more recently deep learning architectures. Relation Extraction systems over Biomedical Corpora are often affected by noisy extraction of entities, due to ambiguities in names of proteins, genes, drugs etc.\n BIBREF12 was one of the first large scale Information Extraction efforts to study the feasibility of extraction of protein-protein interactions (such as “protein A activates protein B\") from Biomedical text. Using 8 hand-crafted regular expressions over a fixed vocabulary, the authors were able to achieve a recall of 30% for interactions present in The Dictionary of Interacting Proteins (DIP) from abstracts in Medline. The method did not differentiate between the type of relation. The reasons for the low recall were the inconsistency in protein nomenclature, information not present in the abstract, and due to specificity of the hand-crafted patterns. On a small subset of extracted relations, they found that about 60% were true interactions between proteins not present in DIP.\n BIBREF13 combine sentence level relation extraction for protein interactions with corpus level statistics. Similar to BIBREF12 , they do not consider the type of interaction between proteins- only whether they interact in the general sense of the word. They also do not differentiate between genes and their protein products (which may share the same name). They use Pointwise Mutual Information (PMI) for corpus level statistics to determine whether a pair of proteins occur together by chance or because they interact. They combine this with a confidence aggregator that takes the maximum of the confidence of the extractor over all extractions for the same protein-pair. The extraction uses a subsequence kernel based on BIBREF14 . The integrated model, that combines PMI with aggregate confidence, gives the best performance. Kernel methods have widely been studied for Relation Extraction in Biomedical Literature. Common kernels used usually exploit linguistic information by utilising kernels based on the dependency tree BIBREF15 , BIBREF16 , BIBREF17 .\n BIBREF18 look at the extraction of diseases and their relevant genes. They use a dictionary from six public databases to annotate genes and diseases in Medline abstracts. In their work, the authors note that when both genes and diseases are correctly identified, they are related in 94% of the cases. The problem then reduces to filtering incorrect matches using the dictionary, which occurs due to false positives resulting from ambiguities in the names as well as ambiguities in abbreviations. To this end, they train a Max-Ent based NER classifier for the task, and get a 26% gain in precision over the unfiltered baseline, with a slight hit in recall. They use POS tags, expanded forms of abbreviations, indicators for Greek letters as well as suffixes and prefixes commonly used in biomedical terms.\n BIBREF19 adopt a supervised feature-based approach for the extraction of drug-drug interaction (DDI) for the DDI-2013 dataset BIBREF20 . They partition the data in subsets depending on the syntactic features, and train a different model for each. They use lexical, syntactic and verb based features on top of shallow parse features, in addition to a hand-crafted list of trigger words to define their features. An SVM classifier is then trained on the feature vectors, with a positive label if the drug pair interacts, and negative otherwise. Their method beats other systems on the DDI-2013 dataset. Some other feature-based approaches are described in BIBREF21 , BIBREF22 .\nDistant supervision methods have also been applied to relation extraction over biomedical corpora. In BIBREF23 , 10,000 neuroscience articles are distantly supervised using information from UMLS Semantic Network to classify brain-gene relations into geneExpression and otherRelation. They use lexical (bag of words, contextual) features as well as syntactic (dependency parse features). They make the “at-least one” assumption, i.e. at least one of the sentences extracted for a given entity-pair contains the relation in database. They model it as a multi-instance learning problem and adopt a graphical model similar to BIBREF24 . They test using manually annotated examples. They note that the F-score achieved are much lesser than that achieved in the general domain in BIBREF24 , and attribute to generally poorer performance of NER tools in the biomedical domain, as well as less training examples. BIBREF25 explore distant supervision methods for protein-protein interaction extraction.\nMore recently, deep learning methods have been applied to relation extraction in the biomedical domain. One of the main advantages of such methods over traditional feature or kernel based learning methods is that they require minimal feature engineering. In BIBREF26 , skip-gram vectors BIBREF27 are trained over 5.6Gb of unlabelled text. They use these vectors to extract protein-protein interactions by converting them into features for entities, context and the entire sentence. Using an SVM for classification, their method is able to outperform many kernel and feature based methods over a variety of datasets.\n BIBREF28 follow a similar method by using word vectors trained on PubMed articles. They use it for the task of relation extraction from clinical text for entities that include problem, treatment and medical test. For a given sentence, given labelled entities, they predict the type of relation exhibited (or None) by the entity pair. These types include “treatment caused medical problem”, “test conducted to investigate medical problem”, “medical problem indicates medical problems”, etc. They use a Convolutional Neural Network (CNN) followed by feedforward neural network architecture for prediction. In addition to pre-trained word vectors as features, for each token they also add features for POS tags, distance from both the entities in the sentence, as well BIO tags for the entities. Their model performs better than a feature based SVM baseline that they train themselves.\nThe BioNLP'16 Shared Tasks has also introduced some Relation Extraction tasks, in particular the BB3-event subtask that involves predicting whether a “lives-in” relation holds for a Bacteria in a location. Some of the top performing models for this task are deep learning models. BIBREF29 train word embeddings with six billions words of scientific texts from PubMed. They then consider the shortest dependency path between the two entities (Bacteria and location). For each token in the path, they use word embedding features, POS type embeddings and dependency type embeddings. They train a unidirectional LSTM BIBREF30 over the dependency path, that achieves an F-Score of 52.1% on the test set.\n BIBREF31 improve the performance by making modifications to the above model. Instead of using the shortest dependency path, they modify the parse tree based on some pruning strategies. They also add feature embeddings for each token to represent the distance from the entities in the shortest path. They then train a Bidirectional LSTM on the path, and obtain an F-Score of 57.1%.\nThe recent success of deep learning models in Biomedical Relation Extraction that require minimal feature engineering is promising. This also suggests new avenues of research in the field. An approach as in BIBREF32 can be used to combine multi-instance learning and distant supervision with a neural architecture.\nMore recently, deep learning methods have been applied to relation extraction in the biomedical domain. One of the main advantages of such methods over traditional feature or kernel based learning methods is that they require minimal feature engineering.",

We note that two of the systems are supervised and rely on the training set to build their classification models. Document frequency counts are also computed on the training set. Stemming is applied to allow more robust matching. The different keyphrase extraction models are briefly described below:\nEach model uses a distinct keyphrase candidate selection method that provides a trade-off between the highest attainable recall and the size of set of candidates. Table summarizes these numbers for each model. Syntax-based selection heuristics, as used by TopicRank and WINGNUS, are better suited to prune candidates that are unlikely to be keyphrases. As for KP-miner, removing infrequent candidates may seem rather blunt, but it turns out to be a simple yet effective pruning method when dealing with long documents. For details on how candidate selection methods affect keyphrase extraction, please refer to BIBREF16 .\nApart from TopicRank that groups similar candidates into topics, the other models do not have any redundancy control mechanism. Yet, recent work has shown that up to 12% of the overall error made by state-of-the-art keyphrase extraction systems were due to redundancy BIBREF6 , BIBREF17 . Therefore as a post-ranking step, we remove redundant keyphrases from the ranked lists generated by all models. A keyphrase is considered redundant if it is included in another keyphrase that is ranked higher in the list.\nTF×IDF: we re-implemented the TF×IDF n-gram based baseline computed by the task organizers. We use 1, 2, 3-grams as keyphrase candidates and filter out those shorter than 3 characters, containing words made of only punctuation marks or one character long13 . Kea (Witten et al., 1999): keyphrase candidates are 1, 2, 3-grams that do not begin or end with a stop- word14. Keyphrases are selected using a na¨ıve bayes classifier15 with two features: TF×IDF and the relative position of first occurrence. TopicRank (Bougouin et al., 2013): keyphrase candidates are the longest sequences of adjacent nouns and adjectives. Lexically similar candidates are clustered into topics and ranked using Tex- tRank (Mihalcea and Tarau, 2004). Keyphrases are produced by extracting the first occurring candidate of the highest ranked topics. KP-Miner (El-Beltagy and Rafea, 2010): keyphrase candidates are sequences of words that do not contain punctuation marks or stopwords. Candidates that appear less than three times or that first occur beyond a certain position are removed16. Candidates are then weighted using a modified TF×IDF formula that account for document length. WINGNUS (Nguyen and Luong, 2010): keyphrase candidates are simplex nouns and noun phrases detected using a set of rules described in (Kim and Kan, 2009). Keyphrases are then selected using a na¨ıve bayes classifier with the optimal set of features found on the training set17: TF×IDF, relative position of first occurrence and candidate length in words.",

Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis). Owing to differences in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be toxic. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue.\n\nUsefulness\nToothpastes are generally useful to maintain dental health. Toothpastes containing fluoride are effective at preventing tooth decay. Toothpastes may also help to control and remove plaque build-up, promoting healthy gums.

The 21st century has brought us the rapid development of media, especially in the internet ecosystem. This change has caused the transfer of many areas of our lives to virtual reality. New forms of communication have been established. Their development has created the need for analysis of related data. Nowadays, unstructured information is available in digital form, but how can we analyse and summarise billions of newly created texts that appear daily on the internet? Natural language analysis techniques, statistics and machine learning have emerged as tools to help us. In recent years, particular attention has focused on sentiment analysis. This area is defined as the study of opinions expressed by people as well as attitudes and emotions about a particular topic, product, event, or person. Sentiment analysis determines the polarisation of the text. It answers the question as to whether a particular text is a positive, negative, or neutral one.\nOur goal is to build a comprehensive set of techniques for preparing and analysing texts containing opinions and generating user-friendly descriptive reports in natural language - Figure FIGREF1 . In this paper, we describe briefly the whole workflow and present a prototype implementation. Currently, existing solutions for sentiment annotation offer mostly analysis on the level of entire documents, and if you go deeper to the level of individual product features, they are only superficial and poorly prepared for the analysis of large volumes of data. This can especially be seen in scientific articles where the analysis is carried out on a few hundred reviews only. It is worth mentioning that this task is extremely problematic because of the huge diversity of languages and the difficulty of building a single solution that can cover all the languages used in the world. Natural language analysis often requires additional pre-processing steps, especially at the stage of preparing the data for analysis, and steps specific for each language. Large differences can be seen in the analysis of the Polish language (a highly inflected language) and English (a grammatically simpler one). We propose a solution that will cover several languages, however in this prototype implementation we focused on English texts only.\nIn this paper, we present analysis and workflow inspired by the work of Joty, Carenini and Ng BIBREF0 . We experimented with several methods in order to validate aspect-based sentiment analysis approaches and in the next steps we want to customise our implementation for the Polish language.\nThe paper presents in Section SECREF1 an introduction to sentiment analysis and its importance in business, then in Section SECREF2 - related work from rhetorical and sentiment analysis areas is presented.

        "question": "Provide a bulleted list of the controversies regarding Uber and a brief summary of each",
        "evidence": "Controversies\n\nIgnoring and evading local regulations\nUber has been criticized for its strategy of generally commencing operations in a city without regard for local regulations. If faced with regulatory opposition, Uber called for public support for its service and mounted a political campaign, supported by lobbying, to change regulations. Uber argued that it is \"a technology company\" and not a taxi company, and therefore it was not subject to regulations affecting taxi companies. Uber's strategy was generally to \"seek forgiveness rather than permission\". In 2014, with regards to airport pickups without a permit in California, drivers were actually told to ignore local regulations and that the company would pay for any citations. Uber's response to California Assembly Bill 5 (2019), whereby it announced that it would not comply with the law, then engaged lobbyists and mounted an expensive public opinion campaign to overturn it via a ballot, was cited as an example of this policy. Taxi companies sued Uber in numerous American cities, alleging that Uber's policy of violating taxi regulations was a form of unfair competition or a violation of antitrust law. Although some courts did find that Uber intentionally violated the taxi rules, Uber prevailed in every case, including the only case to proceed to trial.\n\nIn March 2017, an investigation by The New York Times revealed that Uber developed a software tool called \"Greyball\" to avoid giving rides to known law enforcement officers in areas where its service was illegal such as in Portland, Oregon, Australia, South Korea, and China. The tool identified government officials using geofencing, mining credit card databases, identifying devices, and searches of social media. While at first, Uber stated that it only used the tool to identify riders that violated its terms of service, after investigations by Portland, Oregon, and the United States Department of Justice, Uber admitted to using the tool to skirt local regulations and promised not to use the tool for that purpose. The use of Greyball in London was cited by Transport for London as one of the reasons for its decision not to renew Uber's private hire operator licence in September 2017. A January 2018 report by Bloomberg News stated that Uber routinely used a \"panic button\" system, codenamed \"Ripley\", that locked, powered off and changed passwords on staff computers when those offices were subjected to government raids. Uber allegedly used this button at least 24 times, from spring 2015 until late 2016.\n\nCounter-intelligence research on class action plaintiffs\nIn 2016 Uber hired the global security consulting firm Ergo to secretly investigate plaintiffs involved in a class action lawsuit. Ergo operatives posed as acquaintances of the plaintiff's counsel and tried to contact their associates to obtain information that could be used against them. The result of which was found out causing the judge to throw out evidence obtained as obtained in a fraudulent manner.\n\nSexual harassment allegations and management shakeup (2017)\nOn February 19, 2017, former Uber engineer Susan Fowler published on her website that she was propositioned for sex by a manager and subsequently threatened with termination of employment by another manager if she continued to report the incident. Kalanick was alleged to have been aware of the complaint. On February 27, 2017, Amit Singhal, Uber's Senior Vice President of Engineering, was forced to resign after he failed to disclose a sexual harassment claim against him that occurred while he served as Vice President of Google Search. After investigations led by former attorney general Eric Holder and Arianna Huffington, a member of Uber's board of directors, in June 2017, Uber fired over 20 employees. Kalanick took an indefinite leave of absence but, under pressure from investors, he resigned as CEO a week later. Also departing the company in June 2017 was Emil Michael, a senior vice president who suggested that Uber hire a team of opposition researchers and journalists, with a million-dollar budget, to \"dig up dirt\" on the personal lives and backgrounds of journalists who reported negatively on Uber, specifically targeting Sarah Lacy, editor of PandoDaily, who, in an article published in October 2014, accused Uber of sexism and misogyny in its advertising. In August 2018, Uber agreed to pay a total of $7 million to settle claims of gender discrimination, harassment, and hostile work environment, with 480 employees and former employees receiving $10,700 each and 56 of those employees and former employees receiving an additional $33,900 each. In December 2019, Kalanick resigned from the board of directors of the company and sold his shares.\n\nDelayed disclosure of data breaches\nOn February 27, 2015, Uber admitted that it had suffered a data breach more than nine months prior. Names and license plate information from approximately 50,000 drivers were inadvertently disclosed. Uber discovered this leak in September 2014, but waited more than five months to notify the affected individuals.\n\nAn announcement in November 2017 revealed that in 2016, a separate data breach had disclosed the personal information of 600,000 drivers and 57 million customers. This data included names, email addresses, phone numbers, and drivers' license information. Hackers used employees' usernames and passwords that had been compromised in previous breaches (a \"credential stuffing\" method) to gain access to a private GitHub repository used by Uber's developers. The hackers located credentials for the company's Amazon Web Services datastore in the repository files, and were able to obtain access to the account records of users and drivers, as well as other data contained in over 100 Amazon S3 buckets. Uber paid a $100,000 ransom to the hackers on the promise they would delete the stolen data. Uber was subsequently criticized for concealing this data breach. Khosrowshahi publicly apologized. In September 2018, in the largest multi-state settlement of a data breach, Uber paid $148 million to the Federal Trade Commission, admitted that its claim that internal access to consumers' personal information was closely monitored on an ongoing basis was false, and stated that it had failed to live up to its promise to provide reasonable security for consumer data. Also in November 2018, Uber's British divisions were fined £385,000 (reduced to £308,000) by the Information Commissioner's Office.\n\nIn 2020, the US Department of Justice announced criminal charges against former Chief Security Officer Joe Sullivan for obstruction of justice. The criminal complaint said Sullivan arranged, with Kalanick's knowledge, to pay a ransom for the 2016 breach as a \"bug bounty\" to conceal its true nature, and for the hackers to falsify non-disclosure agreements to say they had not obtained any data.",

        "answer": "They improve on this implementation by training the KG-A2C network in parallel, using the snapshot of the knowledge graph in conjunction with the game state to further encode the current state and use this as a cell representation.",
        "evidence": "In this section, we describe methods to explore combinatorially sized action spaces such as text-games—focusing especially on methods that can deal with their inherent bottleneck structure. We first describe our method that explicitly attempts to detect bottlenecks and then describe how an exploration algorithm such as Go Explore BIBREF9 can leverage knowledge graphs.\nKG-A2C-chained An example of a bottleneck can be seen in Figure FIGREF1. We extend the KG-A2C algorithm as follows. First, we detect bottlenecks as states where the agent is unable to progress any further. We set a patience parameter and if the agent has not seen a higher score in patience steps, the agent assumes it has been limited by a bottleneck. Second, when a bottleneck is found, we freeze the policy that gets the agent to the state with the highest score. The agent then begins training a new policy from that particular state.\nSimply freezing the policy that led to the bottleneck, however, can potentially result in a policy one that is globally sub-optimal. We therefore employ a backtracking strategy that restarts exploration from each of the $n$ previous steps—searching for a more optimal policy that reaches that bottleneck. At each step, we keep track of a buffer of $n$ states and admissible actions that led up to that locally optimal state. We force the agent to explore from this state to attempt to drive it out of the local optima. If it is further unable to find itself out of this local optima, we refresh the training process again, but starting at the state immediately before the agent reaches the local optima. If this continues to fail, we continue to iterate through this buffer of seen states states up to that local optima until we either find a more optimal state or we run out of states to refresh from, in which we terminate the training algorithm.\nKG-A2C-Explore Go-Explore BIBREF9 is an algorithm that is designed to keep track of sub-optimal and under-explored states in order to allow the agent to explore upon more optimal states that may be a result of sparse rewards. The Go-Explore algorithm consists of two phases, the first to continuously explore until a set of promising states and corresponding trajectories are found on the basis of total score, and the second to robustify this found policy against potential stochasticity in the game. Promising states are defined as those states when explored from will likely result in higher reward trajectories. Since the text games we are dealing with are mostly deterministic, with the exception of Zork in later stages, we only focus on using Phase 1 of the Go-Explore algorithm to find an optimal policy. BIBREF10 look at applying Go-Explore to text-games on a set of simpler games generated using the game generation framework TextWorld BIBREF1. Instead of training a policy network in parallel to generate actions used for exploration, they use a small set of “admissible actions”—actions guaranteed to change the world state at any given step during Phase 1—to explore and find high reward trajectories. This space of actions is relatively small (of the order of $10^2$ per step) and so finding high reward trajectories in larger action-spaces such as in Zork would be infeasible\nGo-Explore maintains an archive of cells—defined as a set of states that map to a single representation—to keep track of promising states. BIBREF9 simply encodes each cell by keeping track of the agent's position and BIBREF10 use the textual observations encoded by recurrent neural network as a cell representation. We improve on this implementation by training the KG-A2C network in parallel, using the snapshot of the knowledge graph in conjunction with the game state to further encode the current state and use this as a cell representation. At each step, Go-Explore chooses a cell to explore at random (weighted by score to prefer more advanced cells). The KG-A2C will run for a number of steps, starting with the knowledge graph state and the last seen state of the game from the cell. This will generate a trajectory for the agent while further training the KG-A2C at each iteration, creating a new representation for the knowledge graph as well as a new game state for the cell. After expanding a cell, Go-Explore will continue to sample cells by weight to continue expanding its known states. At the same time, KG-A2C will benefit from the heuristics of selecting preferred cells and be trained on promising states more often.\nWe improve on this implementation by training the KG-A2C network in parallel, using the snapshot of the knowledge graph in conjunction with the game state to further encode the current state and use this as a cell representation.",

And a gold summary consists of $l$ sentences $A=\\lbrace a_1,a_2,\\cdots ,a_l\\rbrace $.\nThe extractor is based on the encoder-decoder framework. We adapt BERT for the encoder to exploit contextualized representations from pre-trained transformers. BERT as the encoder maps the input sequence $D$ to sentence representation vectors $H=\\lbrace h_1,h_2,\\cdots ,h_n\\rbrace $, where $h_i$ is for the $i$-th sentence in the document. Then, the decoder utilizes $H$ to extract $\\hat{D}$ from $D$.\nWe use LSTM Pointer Network BIBREF22 as the decoder to select the extracted sentences based on the above sentence representations. The decoder extracts sentences recurrently, producing a distribution over all of the remaining sentence representations excluding those already selected. Since we use the sequential model which selects one sentence at a time step, our decoder can consider the previously selected sentences. This property is needed to avoid selecting sentences that have overlapping information with the sentences extracted already.\nThe abstractor network approximates $f$, which compresses and paraphrases an extracted document sentence to a concise summary sentence. We use the standard attention based sequence-to-sequence (seq2seq) model BIBREF23, BIBREF24 with the copying mechanism BIBREF25 for handling out-of-vocabulary (OOV) words. Our abstractor is practically identical to the one proposed in BIBREF8.\nOur model consists of two neural network modules, i.e. an extractor and abstractor.

        "question": "What is Assembler?",
        "evidence": "",
        "answer": "An assembler program creates object code by translating combinations of mnemonics and syntax for operations and addressing modes into their numerical equivalents. This representation typically includes an operation code (\"opcode\") as well as other control bits and data. The assembler also calculates constant expressions and resolves symbolic names for memory locations and other entities. The use of symbolic references is a key feature of assemblers, saving tedious calculations and manual address updates after program modifications. Most assemblers also include macro facilities for performing textual substitution – e.g., to generate common short sequences of instructions as inline, instead of called subroutines.\n\nSome assemblers may also be able to perform some simple types of instruction set-specific optimizations. One concrete example of this may be the ubiquitous x86 assemblers from various vendors. Called jump-sizing, most of them are able to perform jump-instruction replacements (long jumps replaced by short or relative jumps) in any number of passes, on request. Others may even do simple rearrangement or insertion of instructions, such as some assemblers for RISC architectures that can help optimize a sensible instruction scheduling to exploit the CPU pipeline as efficiently as possible.",

        "evidence": "Neural Machine Translation (NMT) has shown its effectiveness in translation tasks when NMT systems perform best in recent machine translation campaigns BIBREF0 , BIBREF1 . Compared to phrase-based Statistical Machine Translation (SMT) which is basically an ensemble of different features trained and tuned separately, NMT directly modeling the translation relationship between source and target sentences. Unlike SMT, NMT does not require much linguistic information and large monolingual data to achieve good performances.\nAn NMT consists of an encoder which recursively reads and represents the whole source sentence into a context vector and a recurrent decoder which takes the context vector and its previous state to predict the next target word. It is then trained in an end-to-end fashion to learn parameters which maximizes the likelihood between the outputs and the references. Recently, attention-based NMT has been featured in most state-of-the-art systems. First introduced by BIBREF2 , attention mechanism is integrated in decoder side as feedforward layers. It allows the NMT to decide which source words should take part in the predicting process of the next target words. It helps to improve NMTs significantly. Nevertheless, since the attention mechanism is specific to a particular source sentence and the considering target word, it is also specific to particular language pairs.\nSome recent work has focused on extending the NMT framework to multilingual scenarios. By training such network using parallel corpora in number of different languages, NMT could benefit from additional information embedded in a common semantic space across languages. Basically, the proposed NMT are required to employ multiple encoders or multiple decoders to deal with multilinguality. Furthermore, in order to avoid the tight dependency of the attention mechanism to specific language pairs, they also need to modify their architecture to combine either the encoders or the attention layers. These modifications are specific to the purpose of the tasks as well. Thus, those multilingual NMTs are more complicated, much more free parameters to learn and more difficult to perform standard trainings compared to the original NMT.\nIn this paper, we introduce a unified approach to seamlessly extend the original NMT to multilingual settings. Our approach allows us to integrate any language in any side of the encoder-decoder architecture with only one encoder and one decoder for all the languages involved. Moreover, it is not necessary to do any network modification to enable attention mechanism in our NMT systems. We then apply our proprosed framework in two demanding scenarios: under-resourced translation and zero-resourced translation. The results show that bringing multilinguality to NMT helps to improve individual translations. With some insightful analyses of the results, we set our goal toward a fully multilingual NMT framework.\nThe paper starts with a detailed introduction to attention-based NMT. In Section SECREF3 , related work about multi-task NMT is reviewed. Section SECREF5 describes our proposed approach and thorough comparisons to the related work. It is followed by a section of evaluating our systems in two aforementioned scenarios, in which different strategies have been employed under a unified approach (Section SECREF4 ).

        "question": "Who can help to improve FET performance through their experiments? Introducing information obtained through entity linking or having a deep neural model?",
        "answer": "Bothof them can help.",
        "evidence": "Given a piece of text and the span of an entity mention in this text, fine-grained entity typing (FET) is the task of assigning fine-grained type labels to the mention BIBREF0. The assigned labels should be context dependent BIBREF1. For example, in the sentence “Trump threatens to pull US out of World Trade Organization,” the mention “Trump” should be labeled as /person and /person/politician, although Donald Trump also had other occupations such as businessman, TV personality, etc.\nThis task is challenging because it usually uses a relatively large tag set, and some mentions may require the understanding of the context to be correctly labeled. Moreover, since manual annotation is very labor-intensive, existing approaches have to rely on distant supervision to train models BIBREF0, BIBREF2.\nThus, the use of extra information to help with the classification process becomes very important. In this paper, we improve FET with entity linking (EL). EL is helpful for a model to make typing decisions because if a mention is correctly linked to its target entity, we can directly obtain the type information about this entity in the knowledge base (KB). For example, in the sentence “There were some great discussions on a variety of issues facing Federal Way,” the mention “Federal Way” may be incorrectly labeled as a company by some FET models. Such a mistake can be avoided after linking it to the city Federal Way, Washington. For cases that require the understanding of the context, using entity linking results is also beneficial. In the aforementioned example where “Trump” is the mention, obtaining all the types of Donald Trump in the knowledge base (e.g., politician, businessman, TV personality, etc.) is still informative for inferring the correct type (i.e., politician) that fits the context, since they narrows the possible labels down.\nHowever, the information obtained through EL should not be fully trusted since it is not always accurate. Even when a mention is correctly linked to an entity, the type information of this entity in the KB may be incomplete or outdated. Thus, in this paper, we propose a deep neural fine-grained entity typing model that flexibly predicts labels based on the context, the mention string, and the type information from KB obtained with EL.\nUsing EL also introduces a new problem for the training process. Currently, a widely used approach to create FET training samples is to use the anchor links in Wikipedia BIBREF0, BIBREF3. Each anchor link is regarded as a mention, and is weakly labeled with all the types of its referred entity (the Wikipedia page the anchor link points to) in KB. Our approach, when links the mention correctly, also uses all the types of the referred entity in KB as extra information. This may cause the trained model to overfit the weakly labeled data. We design a variant of the hinge loss and introduce noise during training to address this problem.\nWe conduct experiments on two commonly used FET datasets. Experimental results show that introducing information obtained through entity linking and having a deep neural model both helps to improve FET performance. Our model achieves more than 5% absolute strict accuracy improvement over the state of the art on both datasets.\nOur contributions are summarized as follows:\nWe propose a deep neural fine-grained entity typing model that utilizes type information from KB obtained through entity linking.\nWe address the problem that our model may overfit the weakly labeled data by using a variant of the hinge-loss and introducing noise during training.\nWe demonstrate the effectiveness of our approach with experimental results on commonly used FET datasets.\nOur code is available at https://github.com/HKUST-KnowComp/IFETEL.\nExperimental results show that introducing information obtained through entity linking and having a deep neural model both helps to improve FET performance.",

        "evidence": "We analyse the incremental effect of the different features in our system, focusing on the low-resource setting in Track 1 and using development data.\nEncoding the entire context with an LSTM highly increases the variance of the observed results. So we trained fifty models for each language and each architecture. Figure FIGREF23 visualises the means and standard deviations over the trained models. In addition, we visualise the average accuracy for the five best models for each language and architecture, as these are the models we use in the final ensemble prediction. Below we refer to these numbers only.\nThe results indicate that encoding the full context with an LSTM highly enhances the performance of the model, by 11.15% on average. This observation explains the high results we obtain also for Track 2.\nAdding the auxiliary objective of MSD prediction has a variable effect: for four languages (de, en, es, and sv) the effect is positive, while for the rest it is negative. We consider this to be an issue of insufficient data for the training of the auxiliary component in the low resource setting we are working with.\nWe indeed see results improving drastically with the introduction of multilingual training, with multilingual results being 7.96% higher than monolingual ones on average.\nWe studied the five best models for each language as emerging from the multilingual training (listed in Table TABREF27 ) and found no strong linguistic patterns. The en–sv pairing seems to yield good models for these languages, which could be explained in terms of their common language family and similar morphology. The other natural pairings, however, fr–es, and de–sv, are not so frequent among the best models for these pairs of languages.\nFinally, monolingual finetuning improves accuracy across the board, as one would expect, by 2.72% on average.\nThe final observation to be made based on this breakdown of results is that the multi-tasking approach paired with multilingual training and subsequent monolingual finetuning outperforms the other architectures for five out of seven languages: de, en, fr, ru and sv. For the other two languages in the dataset, es and fi, the difference between this approach and the approach that emerged as best for them is less than 1%.

        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nThe weight initialization reduces the requirement on the training data for the source-target language pair by transferring knowledge from the parent task, thereby improving the performance on the child task.",

        "evidence": "Before joining the Football League, Arsenal played briefly on Plumstead Common, then at the Manor Ground in Plumstead, then spent three years between 1890 and 1893 at the nearby Invicta Ground. Upon joining the Football League in 1893, the club returned to the Manor Ground and installed stands and terracing, upgrading it from just a field. Arsenal continued to play their home games there for the next twenty years (with two exceptions in the 1894–95 season), until the move to north London in 1913.\n\nWidely referred to as Highbury, Arsenal Stadium was the club's home from September 1913 until May 2006. The original stadium was designed by the renowned football architect Archibald Leitch, and had a design common to many football grounds in the UK at the time, with a single covered stand and three open-air banks of terracing. The entire stadium was given a massive overhaul in the 1930s: new Art Deco West and East stands were constructed, opening in 1932 and 1936 respectively, and a roof was added to the North Bank terrace, which was bombed during the Second World War and not restored until 1954.\n\nHighbury could hold more than 60,000 spectators at its peak, and had a capacity of 57,000 until the early 1990s. The Taylor Report and Premier League regulations obliged Arsenal to convert Highbury to an all-seater stadium in time for the 1993–94 season, thus reducing the capacity to 38,419 seated spectators. This capacity had to be reduced further during Champions League matches to accommodate additional advertising boards, so much so that for two seasons, from 1998 to 2000, Arsenal played Champions League home matches at Wembley, which could house more than 70,000 spectators.\n\n\nExpansion of Highbury was restricted because the East Stand had been designated as a Grade II listed building and the other three stands were close to residential properties. These limitations prevented the club from maximising matchday revenue during the 1990s and first decade of the 21st century, putting them in danger of being left behind in the football boom of that time. After considering various options, in 2000 Arsenal proposed building a new 60,361-capacity stadium at Ashburton Grove, since named the Emirates Stadium, about 500 metres south-west of Highbury. The project was initially delayed by red tape and rising costs, and construction was completed in July 2006, in time for the start of the 2006–07 season. The stadium was named after its sponsors, the airline company Emirates, with whom the club signed the largest sponsorship deal in English football history, worth around £100 million. Some fans referred to the ground as Ashburton Grove, or the Grove, as they did not agree with corporate sponsorship of stadium names. The stadium will be officially known as Emirates Stadium until at least 2028, and the airline will be the club's shirt sponsor until at least 2024. From the start of the 2010–11 season on, the stands of the stadium have been officially known as North Bank, East Stand, West Stand and Clock end. The capacity of the Emirates now stands at 60,704.",

In the first scenario we equip the decoder with an additional morphology table including target-side affixes. We place an attention module on top of the table which is controlled by the decoder. At each step, as the decoder samples a character, it searches the table to find the most relevant information which can enrich its state. Signals sent from the table can be interpreted as additional constraints. In the second scenario we share the decoder between two output channels. The first one samples the target character and the other one predicts the morphological annotation of the character. This multi-tasking approach forces the decoder to send morphology-aware information to the final layer which results in better predictions. In the third scenario we combine these two models. Section \"Proposed Architecture\" provides more details on our models.\nIn the first scenario we equip the decoder with an additional morphology table including target-side affixes.",

The Mont-Blanc, laden with high explosives, caught fire and exploded, devastating the Richmond district of Halifax. At least 1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time. It released the equivalent energy of roughly 2.9 kilotons of TNT (12 TJ).\n\nMont-Blanc was under orders from the French government to carry her cargo from New York City via Halifax to Bordeaux, France. At roughly 8:45 am, she collided at low speed, approximately one knot (1.2 mph or 1.9 km/h), with the unladen Imo, chartered by the Commission for Relief in Belgium to pick up a cargo of relief supplies in New York. On the Mont-Blanc, the impact damaged benzol barrels stored on deck, leaking vapours which were ignited by sparks from the collision, setting off a fire on board that quickly grew out of control.

Before proactively taking action to grow the relationship it is essential you first ensure you uphold exceptional neighborly behavior. For example, ensuring loud noises like vacuuming is done during day time and making an effort to upkeep your outdoor space to uplift the shared spaces of your homes. A thoughtful and polite neighbor is more likely to befriend those living around them. There are some ways to build relationships. First, ensure you greet your neighbor with a friendly gesture, such as a wave or a brief verbal greeting, every time you see them. Second, keep a watchful eye for the opportunity to do something friendly for your neighbor. For example, offer to help them if you see them attempting to carry a heavy item. Third, identify a proactive, planned gesture such as offering them a baked sweet around a holiday. Fourth, seek the opportunity to ask them about something they care about. For example, inquire how their work is going or a recent family event they may have mentioned. Fifth, invite them to your home for a meal. There are many ways to build a neighborly relationship and through a combination of these five suggestions, it is likely you will be off to a great start!",

        "question": "Please explain about formula1 qualifying.",
        "evidence": "Qualifying\nFor much of the sport's history, qualifying sessions differed little from practice sessions; drivers would have one or more sessions in which to set their fastest time, with the grid order determined by each driver's best single lap, with the fastest getting first place on the grid, referred to as pole position. From 1996 to 2002, the format was a one-hour shootout. This approach lasted until the end of 2002 before the rules were changed again because the teams were not running in the early part of the session to take advantage of better track conditions later on.\n\nGrids were generally limited to 26 cars – if the race had more entries, qualification would also decide which drivers would start the race. During the early 1990s, the number of entries was so high that the worst-performing teams had to enter a pre-qualifying session, with the fastest cars allowed through to the main qualifying session. The qualifying format began to change in the early 2000s, with the FIA experimenting with limiting the number of laps, determining the aggregate time over two sessions, and allowing each driver only one qualifying lap.\n\nThe current qualifying system was adopted in the 2006 season. Known as \"knock-out\" qualifying, it is split into three periods, known as Q1, Q2, and Q3. In each period, drivers run qualifying laps to attempt to advance to the next period, with the slowest drivers being \"knocked out\" of qualification (but not necessarily the race) at the end of the period and their grid positions set within the rearmost five based on their best lap times. Drivers are allowed as many laps as they wish within each period. After each period, all times are reset, and only a driver's fastest lap in that period (barring infractions) counts. Any timed lap started before the end of that period may be completed, and will count toward that driver's placement. The number of cars eliminated in each period is dependent on the total number of cars entered into the championship.\n\nCurrently, with 20 cars, Q1 runs for 18 minutes, and eliminates the slowest five drivers. During this period, any driver whose best lap takes longer than 107% of the fastest time in Q1 will not be allowed to start the race without permission from the stewards. Otherwise, all drivers proceed to the race albeit in the worst starting positions. This rule does not affect drivers in Q2 or Q3. In Q2, the 15 remaining drivers have 15 minutes to set one of the ten fastest times and proceed to the next period. Finally, Q3 lasts 12 minutes and sees the remaining ten drivers decide the first ten grid positions. At the beginning of the 2016 Formula 1 season, the FIA introduced a new qualifying format, whereby drivers were knocked out every 90 seconds after a certain amount of time had passed in each session. The aim was to mix up grid positions for the race, but due to unpopularity, the FIA reverted to the above qualifying format for the Chinese GP, after running the format for only two races.\n\nEach car is allocated one set of the softest tyres for use in Q3. The cars that qualify for Q3 must return them after Q3; the cars that do not qualify for Q3 can use them during the race. As of 2022, all drivers are given a free choice of tyre to use at the start of the Grand Prix, whereas in previous years only the drivers that did not participate in Q3 had free tyre choice for the start of the race. Any penalties that affect grid position are applied at the end of qualifying. Grid penalties can be applied for driving infractions in the previous or current Grand Prix, or for changing a gearbox or engine component. If a car fails scrutineering, the driver will be excluded from qualifying but will be allowed to start the race from the back of the grid at the race steward's discretion.\n\n2021 has seen the trialling of a 'sprint qualifying' race on the Saturday of three race weekends, with the intention of testing the new approach to qualifying.",

        "question": "Who has annotated the dataset?",
        "answer": "The dataset was originally annotated by the first author and part of the dataset was annotated by a second linguist.",
        "evidence": "The dataset consists of 66,723 sentences with 2,157,048 tokens (incl. punctuation), see Table . The sizes of the seven court-specific datasets varies between 5,858 and 12,791 sentences, and 177,835 to 404,041 tokens. The distribution of annotations on a per-token basis corresponds to approx. 19–23 %. The Federal Patent Court (BPatG) dataset contains the lowest number of annotated entities (10.41 %).\nThe dataset includes two different versions of annotations, one with a set of 19 fine-grained semantic classes and another one with a set of 7 coarse-grained classes (Table ). There are 53,632 annotated entities in total, the majority of which (74.34 %) are legal entities, the others are person, location and organization (25.66 %). Overall, the most frequent entities are law GS (34.53 %) and court decision RS (23.46 %). The other legal classes (ordinance VO, European legal norm EUN, regulation VS, contract VT, and legal literature LIT) are much less frequent (1–6 % each). Even less frequent (less than 1 %) are lawyer AN, street STR, landscape LDS, and brand MRK.\nThe classes person, lawyer and company are heavily affected by the anonymisation process (80 %, 95 % and 70 % respectively). More than half of city and street, about 55 %, have also been modified. Landscape and organization are affected as well, with 40 % and 15 % of the occurrences edited accordingly. However, anonymisation is typically not applied to judge, country, institution and court (1–5 %).\nThe dataset was originally annotated by the first author. To evaluate and potentially improve the quality of the annotations, part of the dataset was annotated by a second linguist (using the annotation guidelines specifically prepared for its construction). We selected a small part that could be annotated in approx. two weeks. For the sentence extraction we paid special attention to the anonymised mentions of person, location or organization entities, because these are usually explained at their first mention. The resulting sample consisted of 2005 sentences with a broad variety of different entities (3 % of all sentences from each federal court). The agreement between the two annotators was measured using Kappa on a token basis. All class labels were taken into account in accordance with the IOB2 scheme BIBREF18. The inter-annotator agreement is 0.89, i. e., there is mostly very good agreement between the two annotators. Differences were in the identification of court decision and legal literature. Some unusual references of court decision (consisting only of decision type, court, date, file number) were not annotated such as `Urteil des Landgerichts Darmstadt vom 16. April 2014 – 7 S 8/13 –'. Apart from missing legal literature annotations, author names and law designations were annotated according to their categories (i. e., `Schoch, in: Schoch/Schneider/Bier, VwGO § 123 Rn. 35', `Bekanntmachung des BMG gemäß §§ 295 und 301 SGB V zur Anwendung des OPS vom 21.10.2010').\nThe second annotator had difficulties annotating the class law, not all instances were identified (`§ 272 Abs. 1a und 1b HGB', `§ 3c Abs. 2 Satz 1 EStG'), others only partially (`§ 716 in Verbindung mit' in `§ 716 in Verbindung mit §§ 321 , 711 ZPO'). Some titles of contract were not recognised and annotated (`BAT', `TV-L', `TVÜ-Länder' etc.).\nThis evaluation has revealed deficiencies in the annotation guidelines, especially regarding court decision and legal literature as well as non-entities. It would also be helpful for the identification and classification to list well-known sources of law, court decision, legal literature etc.\nThe dataset was originally annotated by the first author.

        "evidence": "Word embeddings are fixed-length vector representations for words BIBREF0 , BIBREF1 . In recent years, the morphology of words is drawing more and more attention BIBREF2 , especially for Chinese whose writing system is based on logograms.\nUTF8gbsn With the gradual exploration of the semantic features of Chinese, scholars have found that not only words and characters are important semantic carriers, but also stroke feature of Chinese characters is crucial for inferring semantics BIBREF3 . Actually, a Chinese word usually consists of several characters, and each character can be further decomposed into a stroke sequence which is certain and changeless, and this kind of stroke sequence is very similar to the construction of English words. In Chinese, a particular sequence of strokes can reflect the inherent semantics. As shown in the upper half of Figure FIGREF3 , the Chinese character “驾\" (drive) can be decomposed into a sequence of eight strokes, where the last three strokes together correspond to a root character “马\" (horse) similar to the root “clar\" of English word “declare\" and “clarify\".\nMoreover, Chinese is a language originated from Oracle Bone Inscriptions (a kind of hieroglyphics). Its character glyphs have a spatial structure similar to graphs which can convey abundant semantics BIBREF4 . Additionally, the critical reason why Chinese characters are so rich in morphological information is that they are composed of basic strokes in a 2-D spatial order. However, different spatial configurations of strokes may lead to different semantics. As shown in the lower half of Figure 1, three Chinese characters “入\" (enter), “八\" (eight) and “人\" (man) share exactly a common stroke sequence, but they have completely different semantics because of their different spatial configurations.\nIn addition, some biological investigations have confirmed that there are actually two processing channels for Chinese language. Specifically, Chinese readers not only activate the left brain which is a dominant hemisphere in processing alphabetic languages BIBREF5 , BIBREF6 , BIBREF7 , but also activate the areas of the right brain that are responsible for image processing and spatial information at the same time BIBREF8 . Therefore, we argue that the morphological information of characters in Chinese consists of two parts, i.e., the sequential information hidden in root-like strokes order, and the spatial information hidden in graph-like character glyphs. Along this line, we propose a novel Dual-channel Word Embedding (DWE) model for Chinese to realize the joint learning of sequential and spatial information in characters. Finally, we evaluate DWE on two representative tasks, where the experimental results exactly validate the superiority of DWE in capturing the morphological information of Chinese.\nFinally, we evaluate DWE on two representative tasks, where the experimental results exactly validate the superiority of DWE in capturing the morphological information of Chinese.",

Second, be sure to review your newly acquired houseplant for any pests before introducing them into your home. You’ll want to check the leaves for mealy bugs, spider mites, etc. and the soil for pests such as fungus gnats. If you find any of these be sure to quarantine your new plant away from your current plants and treat with a pesticide of your choosing. Many houseplant owners use neem oil to treat pests. Third, upsize or repot your plant only when it is ready. Your new plant likely will be happy for a while in its current nursery (plastic) container that it came home from the shop in. You can choose to upsize the pot once you notice signs of the plant being root bound (the roots take up a majority of the pot) such as water draining from the pot quickly and the soil not becoming saturated or the plant slows its growth of new leaves (unless its the winter season at which time plants naturally slow or stop new growth).

        "question": "How does a transistor amplify a signal?",
        "evidence": "",
        "answer": "A transistor is a constructed from materials that behave as semiconductors--which is to say that these materials conduct electrical current but only when certain conditions are met. By combining these materials into a device called a transistor we are able to create an electronic component that will only conduct electricity when a small electric current is applied to the so-called Base pin of the transistor.\n\nOne obvious use of such behavior is to use the transistor as a switch--by applying or removing current to the base pin we are able to control whether the transistor conducts electricity via its collector and emitter pins. When no current is present at the Base pin the transistor will block electrical transmission through its emitter and collector pins.\n\nGenerally speaking, the electrical current required to control the transistor at the base pin is very small. Much larger currents can be transferred through the device through the collector and emitter pins. Thus, in effect, a transistor uses a very small input current to control the flow of a much larger current.\n\nAn audio signal, for example, is transmitted as a very low power electrical current--in it's original form it is too small to be able to drive a loudspeaker to make sounds that are audible to the human ear. To amplify this signal so that is usable for audio playback we can apply the audio signal to a transistor's base pin--this will allow a much larger current to flow between the emitter and collector pins and through the transistor. Since the flow of this large current will mirror the much smaller current of the audio signal we will have effectively created a much stronger version of the original input signal.",

Each operation is regarded as a relational tuple by viewing the operator as relation, e.g., $(add, n1, n2)$. We test TP-N2F for this task on the MathQA dataset BIBREF16. The MathQA dataset consists of about 37k math word problems, each with a corresponding list of multi-choice options and the corresponding operation sequence. In this task, TP-N2F is deployed to generate the operation sequence given the question. The generated operations are executed with the execution script from BIBREF16 to select a multi-choice answer. As there are about 30% noisy data (where the execution script returns the wrong answer when given the ground-truth program; see Sec. SECREF20 of the Appendix), we report both execution accuracy (of the final multi-choice answer after running the execution engine) and operation sequence accuracy (where the generated operation sequence must match the ground truth sequence exactly).

Actually, we aim for a saddle point, finding the parameters $\\Theta $ and $\\Theta ^{\\prime }$ satisfying the following conditions: \n$$\\begin{split}\n\\hat{\\Theta } &= \\mathop {arg~min}_{\\Theta }\\text{R}(\\Theta , \\Theta ^{\\prime }, \\mathbf {X}, \\mathbf {\\bar{y}}, \\bar{z}) \\\\\n\\hat{\\Theta }^{\\prime } &= \\mathop {arg~max}_{\\Theta ^{\\prime }}\\text{R}(\\hat{\\Theta }, \\Theta ^{\\prime }, \\mathbf {X}, \\mathbf {\\bar{y}}, \\bar{z}) \\\\\n\\end{split}$$   (Eq. 24) \nwhere the first equation aims to find one $\\Theta $ that minimizes our new objective $\\text{R}(\\cdot )$ , and the second equation aims to find one $\\Theta ^{\\prime }$ maximizing the same objective.\nIntuitively, the first equation of Formula 24 tries to minimize the NER loss, but at the same time maximize the worker discriminator loss by the shared parameters of the common Bi-LSTM. Thus the resulting features of common Bi-LSTM actually attempt to hurt the worker discriminator, which makes these features worker independent since they are unable to distinguish different workers. The second equation tries to minimize the worker discriminator loss by its own parameter $\\Theta ^{\\prime }$ .\nWe use the standard back-propagation method to train the model parameters, the same as the baseline model. In order to incorporate the term of the argmax part of Formula 24 , we follow the previous work of adversarial training BIBREF13 , BIBREF15 , BIBREF17 , by introducing a gradient reverse layer between the common Bi-LSTM and the CNN module, whose forward does nothing but the backward simply negates the gradients.\nWe use the standard back-propagation method to train the model parameters, the same as the baseline model.",

        "question": "How much renewable energy is produced and consumed in the United States?",
        "evidence": "According to preliminary data from the US Energy Information Administration, renewable energy accounted for about 12.6% of total primary energy consumption and about 19.8% of the domestically produced electricity in the United States in 2020.",
        "answer": "Since 2019, wind power has been the largest producer of renewable electricity in the country. Wind power generated 337.9 terawatt-hours of electricity in 2020, which accounted for 8.4% of the nation's total electricity generation and 43.2% of the total renewable electricity generation.  By October 2021, the United States nameplate generating capacity for wind power was 129,256 megawatts (MW).  Texas remained firmly established as the leader in wind power deployment, followed by Iowa and Oklahoma as of year end 2020.\n\nHydroelectric power is the second-largest producer of renewable electricity in the country, generating around 7.3% of the nation's total electricity in 2020 as well as 36.4% of the total renewable electricity generation.  The United States is the fourth largest producer of hydroelectricity in the world after China, Canada and Brazil.\n\nSolar power provides a growing share of electricity in the country, with over 50 GW of installed capacity generating about 1.3% of the country's total electricity supply in 2017, up from 0.9% the previous year. As of 2016, more than 260,000 people worked in the solar industry and 43 states deployed net metering, where energy utilities bought back excess power generated by solar arrays.  Large photovoltaic power plants in the United States include Mount Signal Solar (600 MW) and Solar Star (579 MW). Since the United States pioneered solar thermal power technology in the 1980s with Solar One, several more such power stations have been built. The largest of these solar thermal power stations are the Ivanpah Solar Power Facility (392 MW), southwest of Las Vegas, and the SEGS group of plants in the Mojave Desert, with a total generating capacity of 354 MW.\n\nOther renewable energy sources include geothermal, with The Geysers in Northern California the largest geothermal complex in the world.\n\nThe development of renewable energy and energy efficiency marked \"a new era of energy exploration\" in the United States, according to former President Barack Obama.  In a joint address to the Congress on February 24, 2009, President Obama called for doubling renewable energy within the following three years. Renewable energy reached a major milestone in the first quarter of 2011, when it contributed 11.7% of total national energy production (660 TWh), surpassing energy production from nuclear power (620 TWh) for the first time since 1997.  In his 2012 State of the Union address, President Barack Obama restated his commitment to renewable energy and mentioned the long-standing Interior Department commitment to permit 10,000 MW of renewable energy projects on public land in 2012.",

The first method simply adopts a sampling scheme, which randomly selects training data from the auxiliary tasks controlled by a ratio hyperparameter; The second algorithm incorporates recent ideas of data selection in machine translation BIBREF7 . It learns the sample weights from the auxiliary tasks automatically through language models. Prior to this work, many studies have used upstream datasets to augment the performance of MRC models, including word embedding BIBREF5 , language models (ELMo) BIBREF8 and machine translation BIBREF1 . These methods aim to obtain a robust semantic encoding of both passages and questions. Our MTL method is orthogonal to these methods: rather than enriching semantic embedding with external knowledge, we leverage existing MRC datasets across different domains, which help make the whole comprehension process more robust and universal. Our experiments show that MTL can bring further performance boost when combined with contextual representations from pre-trained language models, e.g., ELMo BIBREF8 .\nWe develop a novel re-weighting method to resolve these problems, using ideas inspired by data selection in machine translation BIBREF26 , BIBREF7 . We use $(Q^{k},P^{k},A^{k})$ to represent a data point from the $k$ -th task for $1\\le k\\le K$ , with $k=1$ being the target task. Since the passage styles are hard to evaluate, we only evaluate data points based on $Q^{k}$ and $A^k$ .

        "evidence": "",
        "answer": "As a first attempt to answer the question of why human beings have a tendency to think they are always right, we could point to cognitive biases, and in particular to one called \"confirmation bias\". This bias conditions human beings to use any new evidence to confirm their pre-existing beliefs, and to reject any new evidence that contradicts these beliefs. People may also experience the so-called illusory superiority, another bias that conditions them to overestimate their skills and make them believe they are superior to the rest. However these biases, as concrete as well-proven as they are, are only part of the explanation. The book \"Being Wrong: Adventures in the Margin of Error\" by Kathryn Schulz is an exploration on why humans have the tendency to disregard errors and think they are always right. Shulz describes how people start with the assumption that they are right in everything they believe, and when they realise they have made a mistake, instead of challenging this assumption, they actually feel relief and think: \"I was right except for this particular error I was making, but now that I have realised it I can certainly say that I am 100% right in everything\".",

        "evidence": "This work is most closely related to the paper from which we get the ERP data: BIBREF0 . In that work, the authors relate the surprisal of a word, i.e. the (negative log) probability of the word appearing in its context, to each of the ERP signals we consider here. The authors do not directly train a model to predict ERPs. Instead, models of the probability distribution of each word in context are used to compute a surprisal for each word, which is input into a mixed effects regression along with word frequency, word length, word position in the sentence, and sentence position in the experiment. The effect of the surprisal is assessed using a likelihood-ratio test. In BIBREF7 , the authors take an approach similar to BIBREF0 . The authors compare the explanatory power of surprisal (as computed by an LSTM or a Recurrent Neural Network Grammar (RNNG) language model) to a measure of syntactic complexity they call “distance\" that counts the number of parser actions in the RNNG language model. The authors find that surprisal (as predicted by the RNNG) and distance are both significant factors in a mixed effects regression which predicts the P600, while the surprisal as computed by an LSTM is not. Unlike BIBREF0 and BIBREF7 , we do not use a linking function (e.g. surprisal) to relate a language model to ERPs. We thus lose the interpretability provided by the linking function, but we are able to predict a significant proportion of the variance for all of the ERP components, where prior work could not. We interpret our results through characterization of the ERPs in terms of how they relate to each other and to eye-tracking data rather than through a linking function. The authors in BIBREF8 also use a recurrent neural network to predict neural activity directly. In that work the authors predict magnetoencephalography (MEG) activity, a close cousin to EEG, recorded while participants read a chapter of Harry Potter and the Sorcerer’s Stone BIBREF9 . Their approach to characterization of processing at each MEG sensor location is to determine whether it is best predicted by the context vector of the recurrent network (prior to the current word being processed), the embedding of the current word, or the probability of the current word given the context. In future work we also intend to add these types of studies to the ERP predictions.\nIn Hale et al. (2018), the authors take an approach similar to Frank et al. (2015).

        "answer": "While there are some similarities between 2023 and 2008, I do not believe this is a similar crisis.  The biggest difference is that in 2008, nearly every bank had widespread exposure to mortgage backed securities.  In the 2023 crisis, it is only a few banks that had overexposure to treasuries without any hedge against rising interest rates.   Additionally, in 2008, while two different banks collapsed, there was much more widespread fear amongst the banks that caused a credit crunch.  Banks were unwilling to lend each other money for fear of liquidity problems, which in turned led to the credit markets freezing and causing secondary problems of companies being unable to attain lines of credit to meet payroll.   In 2023, there was also a failure of 2 banks, but the failure stemmed from a traditional bank run where depositors, en mass, were attempting to withdraw their funds at the same time, causing a liquidity problem with the affected banks.",

        "evidence": "In recent years, content delivery has changed drastically, shifting from offline methods to the Internet. It is now the primary source of information for a majority of the populace, especially for ever-changing news updates. This has also caused a shift in users' preferred sources. Previously, these preferences were static, sticking to a particular news source. Now, with the plethora of information available easily, there is no differentiation in the source it has been gathered from, with users opting to go for whatever is convenient.\nKeeping up with the times, news agencies have expanded their digital presence, increasing their reach exponentially. They generate revenue by (1) advertisements on their websites, or (2) a subscription based model for articles that might interest users. Since multiple agencies offer similar content, the user has his pick. To lure in more readers and increase the number of clicks on their content, subsequently enhancing their agency's revenue, writers have begun adopting a new technique - clickbait.\nMerriam-Webster defines clickbait as something (such as a headline) to encourage readers to click on hyperlinks based on snippets of information accompanying it, especially when those links lead to content of dubious value or interest. It is built to create, and consequently capitalise, on the Loewenstein information gap BIBREF0 by purposefully misrepresenting or promising what can be expected while reading a story on the web, be it through a headline, image or related text.\nWe propose a two-pronged approach to detect such headlines. The first component leverages distributional semantics of the title text and models its temporal and sequential properties. The article title is represented as a concatenation of its sub-word level embeddings. The sub-word representation serves as input to a bidirectional LSTM network. The contribution of a sub-word towards the clickbait nature of the headline is calculated in a differential manner since the output of the LSTM is passed into an attention layer BIBREF1 , following which it goes through a dense layer. The second component focuses on Doc2Vec embeddings of the title and article content, performing an element wise multiplication of the two. This is concatenated with the dense layer output from the previous component. The obtained output is then passed through multiple hidden layers which performs the final classification.\nPrevious work in this field that has exploited the power of embeddings has considered either word vectors, for their ability to create context-sensitive word representations, or character-level word embeddings to model the orthographic features of a word. We propose the use of sub-word level representations since it incorporates the word's morphological features. Attaching an attention mechanism to it helps us identify the surprise associated with each representation within the clickbait. One of the identifying characteristics of clickbait is that the article title differs from the text attached to it. For this reason, we define a component to capture the interaction between these attributes and augment our model.\nThe first component leverages distributional semantics of the title text and models its temporal and sequential properties.

        "evidence": "Unlike the conventional smooth nonconvex finite-sum problem where each mini-batch is iid-sampled from the dataset P ∪ C, the replay memory based continual learning encounters a non-iid stream of data C and has access to a small sized memory M . Algorithm 1 presents the pseudocode of NCCL by Equation. By the limited access to P , the gradient update for f (x) in Equation is a biased estimate of the gradient ∇f (x t ). Specifically, at the timestep t,\nwhere e t and e Mt denote the error term ∇f It (x t ) − ∇f (x t ) and the expectation value over I t given M t , respectively. We note that the given replay memory M t with small size at timestep t induces the inevitable overfitting bias. We first state an intermediate result for a single gradient update of NCCL.\nFor ease of exposition, we define the overfitting term B t and the catastrophic forgetting term Γ t as follows:\nB t = (Lα 2 Ht − α Ht ) ∇f (x t ), e t + β Ht ∇g Jt (x t ), e t ,\nwhere L is a constant for Lipschitz smoothness. Under Assumption 1, a single gradient update by Equation 7 satisfies the following bound by letting x ← x t+1 and y ← x t :\nThis reveals the basic qualitative difference between the conventional nonconvex SGD and NCCL in the convergence rate. Compared to the nonconvex SGD, there exist two terms B t and Γ t in Equation. We group the terms containing e t as B t and the other terms as Γ t . We note that the catastrophic forgetting term Γ t has ∇f It (x t ), ∇g Jt (x t ) , which is the key aspect of interference and transer, and B t includes the error term between the batch of M and the entire dataset P . Then, we can quantify the amount of overfitting by tracing B t .\nTo compute the expectation over the stochasticity of NCCL, we derive the expectation of ∇f Mt (x t ) over the sampling rule of M t . The episodic memory M t = M 0 for all t is uniformly sampled once from the random sequence of P , and ER-reservoir iteratively samples the replay memory M t by the selection probability\nIf M 0 is uniformly sampled from P , then both episodic memory and ER-reservoir satisfies\nWe provide the detailed proof in Appendix B. Note that taking expectation iteratively with respect to the history M [0:t] is needed to compute the expected value of gradients for M t . Since taking the expectation over the stochasticity of NCCL implies the total expectation\nAlgorithm 1 Nonconvex Continual Learning (NCCL)\nCompute learning rates α Ht and β Ht with ∇f It (x t ) and ∇g Jt (x t )\nStore J t into M t+1 by the rule of replay memory scheme end for\nis also 0. We note that considering a random choice of M 0 allows us to analyze the convergence on f (x), even if M 0 cannot access the all datapoints in P to compute ∇f (x t ) 2 . Our first main result is the following lemma that provides the stepwise change of upper bound. Lemma 2. Suppose that Assumption 1 holds and 0<α Ht ≤ 2 L . Then for x t updated by Algorithm 1, we have the following bound\nwhere the effect of B t vanishes by\nThe proof is presented in Appendix B. Surprisingly, taking the expectation over M 0 ⊂ P in Equation to handle the stochasticity of choosing M 0 allows us to analyze the convergence of f (x) in Section 3.3. We also note that the individual trial with a randomly given M 0 cannot cancel the effect by B t , although its total expectation over the whole possible trials E[B t ] is zero. More specifically, the worst case sup M0 ∇f (x t ) 2 definitely contains the non-zero value of B t in the upper bound term. We discuss the more details of the overfitting to memory in Appendix D.\nThis reveals the basic qualitative difference between the conventional nonconvex SGD and NCCL in the convergence rate.

People turn to Twitter for a variety of purposes, from everyday chatter to reading about breaking news. The volume plus the public nature of Twitter (less than 10% of Twitter accounts are private BIBREF0 ) have made Twitter a great source of data for social and behavioural studies. These studies often require an understanding of what people are tweeting about. Though this can be coded manually, in order to take advantage of the volume of tweets available automatic analytic methods have to be used. There has been extensive work done on computational methods for analysing the linguistic content of tweets. However, there has been very little work done on classifying the pragmatics of tweets. Pragmatics looks beyond the literal meaning of an utterance and considers how context and intention contribute to meaning. A major element of pragmatics is the intended communicative act of an utterance, or what the utterance was meant to achieve. It is essential to study pragmatics in any linguistic system because at the core of linguistic analysis is studying what language is used for or what we do with language. Linguistic communication and meaning can not truly be studied without studying pragmatics. Proposed by Austin BIBREF1 and refined by Searle BIBREF2 , speech act theory can be used to study pragmatics. Amongst other things, the theory provides a formalized taxonomy BIBREF3 of a set of communicative acts, more commonly known as speech acts.\nThere has been extensive research done on speech act (also known as dialogue act) classification in computational linguistics, e.g., BIBREF4 . Unfortunately, these methods do not map well to Twitter, given the noisy and unconventional nature of the language used on the platform. In this work, we created a supervised speech act classifier for Twitter, using a manually annotated dataset of a few thousand tweets, in order to be better understand the meaning and intention behind tweets and uncover the rich interactions between the users of Twitter. Knowing the speech acts behind a tweet can help improve analysis of tweets and give us a better understanding of the state of mind of the users. Moreover, ws we have shown in our previous works BIBREF5 , BIBREF6 , speech act classification is essential for detection of rumors on Twitter. Finally, knowing the distribution of speech acts of tweets about a particular topic can reveal a lot about the general attitude of users about that topic (e.g., are they confused and are asking a lot of questions? Are they outraged and demanding action? Etc).\nThere has been extensive research done on speech act (also known as dialogue act) classification in computational linguistics, e.g., (Stolcke et al. 2000).

        "question": "What features can the multilingual model capture?",
        "answer": "Both language-independent and language-dependent features.",
        "evidence": "Neural machine translation (NMT) exploits neural networks to directly learn to transform sentences from a source language to a target language BIBREF0 , BIBREF1 . Universal multilingual NMT discovered that a neural translation system can be trained on datasets containing source and target sentences in multiple languages BIBREF2 , BIBREF3 . Successfully trained models using this approach can be used to translate arbitrarily between any languages included in the training data. In low-resource scenarios, multilingual NMT has proven to be an extremely useful regularization method since each language direction benefits from the information of the others BIBREF4 , BIBREF5 .\nAn important research focus of multilingual NMT is zero-shot translation (ZS), or translation between languages included in multilingual data for which no directly parallel training data exists. Application-wise, ZS offers a faster and more direct path between languages compared to pivot translation, which requires translation to one or many intermediate languages. This can result in large latency and error propagation, common issues in non-end-to-end pipelines.From a representation learning point of view, there is evidence of NMT's ability to capture language-independent features, which have proved useful for cross-lingual transfer learning BIBREF6 , BIBREF7 and provide motivation for ZS translation. However it is still unclear if minimizing the difference in representations between languages is beneficial for zero-shot learning.\nOn the other hand, the current neural architecture and learning mechanisms of multilingual NMT is not geared towards having a common representation. Different languages are likely to convey the same semantic content with sentences of different lengths BIBREF8 , which makes the desiderata difficult to achieve. Moreover, the loss function of the neural translation model does not favour having sentences encoded in the same representation space regardless of the source language. As a result, if the network capacity is large enough, it may partition itself into different sub-spaces for different language pairs BIBREF9 .\nOur work here focuses on the zero-shot translation aspect of universal multilingual NMT. First, we attempt to investigate the relationship of encoder representation and ZS performance. By modifying the Transformer architecture of BIBREF10 to afford a fixed-size representation for the encoder output, we found that we can significantly improve zero-shot performance at the cost of a lower performance on the supervised language pairs. To the best of our knowledge, this is the first empirical evidence showing that the multilingual model can capture both language-independent and language-dependent features, and that the former can be prioritized during training.\nThis observation leads us to the most important contribution in this work, which is to propose several techniques to learn a joint semantic space for different languages in multilingual models without any architectural modification. The key idea is to prefer a source language-independent representation in the decoder using an additional loss function. As a result, the NMT architecture remains untouched and the technique is scalable to the number of languages in the training data. The success of this method is shown by significant gains on zero-shot translation quality in the standard IWSLT 2017 multilingual benchmark BIBREF11 . Finally, we introduce a more challenging scenario that involves more than one bridge language between source and target languages. This challenging setup confirms the consistency of our zero-shot techniques while clarifying the disadvantages of pivot-based translation.\nTo the best of our knowledge, this is the first empirical evidence showing that the multilingual model can capture both language-independent and language-dependent features, and that the former can be prioritized during training.",

        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nWe test our system on the CALLHOME Spanish-English speech translation corpus, a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ).",

        "evidence": "We posses a wealth of prior knowledge about many natural language processing tasks. For example, in text categorization, we know that words such as NBA, player, and basketball are strong indicators of the sports category BIBREF0 , and words like terrible, boring, and messing indicate a negative polarity while words like perfect, exciting, and moving suggest a positive polarity in sentiment classification.\nA key problem arisen here, is how to leverage such knowledge to guide the learning process, an interesting problem for both NLP and machine learning communities. Previous studies addressing the problem fall into several lines. First, to leverage prior knowledge to label data BIBREF1 , BIBREF2 . Second, to encode prior knowledge with a prior on parameters, which can be commonly seen in many Bayesian approaches BIBREF3 , BIBREF4 . Third, to formalise prior knowledge with additional variables and dependencies BIBREF5 . Last, to use prior knowledge to control the distributions over latent output variables BIBREF6 , BIBREF7 , BIBREF8 , which makes the output variables easily interpretable.\nHowever, a crucial problem, which has rarely been addressed, is the bias in the prior knowledge that we supply to the learning model. Would the model be robust or sensitive to the prior knowledge? Or, which kind of knowledge is appropriate for the task? Let's see an example: we may be a baseball fan but unfamiliar with hockey so that we can provide a few number of feature words of baseball, but much less of hockey for a baseball-hockey classification task. Such prior knowledge may mislead the model with heavy bias to baseball. If the model cannot handle this situation appropriately, the performance may be undesirable.\nIn this paper, we investigate into the problem in the framework of Generalized Expectation Criteria BIBREF7 . The study aims to reveal the factors of reducing the sensibility of the prior knowledge and therefore to make the model more robust and practical. To this end, we introduce auxiliary regularization terms in which our prior knowledge is formalized as distribution over output variables. Recall the example just mentioned, though we do not have enough knowledge to provide features for class hockey, it is easy for us to provide some neutral words, namely words that are not strong indicators of any class, like player here. As one of the factors revealed in this paper, supplying neutral feature words can boost the performance remarkably, making the model more robust.\nMore attractively, we do not need manual annotation to label these neutral feature words in our proposed approach.\nMore specifically, we explore three regularization terms to address the problem: (1) a regularization term associated with neutral features; (2) the maximum entropy of class distribution regularization term; and (3) the KL divergence between reference and predicted class distribution. For the first manner, we simply use the most common features as neutral features and assume the neutral features are distributed uniformly over class labels. For the second and third one, we assume we have some knowledge about the class distribution which will be detailed soon later.\nTo summarize, the main contributions of this work are as follows:\nThe rest of the paper is structured as follows: In Section 2, we briefly describe the generalized expectation criteria and present the proposed regularization terms. In Section 3, we conduct extensive experiments to justify the proposed methods. We survey related work in Section 4, and summarize our work in Section 5.\nMore specifically, we explore three regularization terms to address the problem:",

        "question": "Do the embedding features generalize well across domains in the task of argument component identification?",
        "answer": "Yes, they do.",
        "evidence": "In the following experiment, we focus on automatic identification of arguments in the discourse. Our approach is based on supervised and semi-supervised machine learning methods on the gold data Toulmin dataset introduced in section SECREF51 .\nAn argument consists of different components (such as premises, backing, etc.) which are implicitly linked to the claim. In principle one document can contain multiple independent arguments. However, only 4% of the documents in our dataset contain arguments for both sides of the issue. Thus we simplify the task and assume there is only one argument per document.\nGiven the low inter-annotator agreement on the pathos dimension (Table TABREF77 ), we focus solely on recognizing the logical dimension of argument. The pathos dimension of argument remains an open problem for a proper modeling as well as its later recognition.\nSince the smallest annotation unit is a token and the argument components do not overlap, we approach identification of argument components as a sequence labeling problem. We use the BIO encoding, so each token belongs to one of the following 11 classes: O (not a part of any argument component), Backing-B, Backing-I, Claim-B, Claim-I, Premise-B, Premise-I, Rebuttal-B, Rebuttal-I, Refutation-B, Refutation-I. This is the minimal encoding that is able to distinguish two adjacent argument components of the same type. In our data, 48% of all adjacent argument components of the same type are direct neighbors (there are no \"O\" tokens in between).\nWe report Macro- INLINEFORM0 score and INLINEFORM1 scores for each of the 11 classes as the main evaluation metric. This evaluation is performed on the token level, and for each token the predicted label must exactly match the gold data label (classification of tokens into 11 classes).\nAs instances for the sequence labeling model, we chose sentences rather than tokens. During our initial experiments, we observed that building a sequence labeling model for recognizing argument components as sequences of tokens is too fine-grained, as a single token does not convey enough information that could be encoded as features for a machine learner. However, as discussed in section UID73 , the annotations were performed on data pre-segmented to sentences and annotating tokens was necessary only when the sentence segmentation was wrong or one sentence contained multiple argument components. Our corpus consists of 3899 sentences, from which 2214 sentences (57%) contain no argument component. From the remaining ones, only 50 sentences (1%) have more than one argument component. Although in 19 cases (0.5%) the sentence contains a Claim-Premise pair which is an important distinction from the argumentation perspective, given the overall small number of such occurrences, we simplify the task by treating each sentence as if it has either one argument component or none.\nThe approximation with sentence-level units is explained in the example in Figure FIGREF112 . In order to evaluate the expected performance loss using this approximation, we used an oracle that always predicts the correct label for the unit (sentence) and evaluated it against the true labels (recall that the evaluation against the true gold labels is done always on token level). We lose only about 10% of macro INLINEFORM0 score (0.906) and only about 2% of accuracy (0.984). This performance is still acceptable, while allowing to model sequences where the minimal unit is a sentence.\nTable TABREF114 shows the distribution of the classes in the gold data Toulmin, where the labeling was already mapped to the sentences. The little presence of rebuttal and refutation (4 classes account only for 3.4% of the data) makes this dataset very unbalanced.\nWe chose SVMhmm BIBREF111 implementation of Structural Support Vector Machines for sequence labeling. Each sentence ( INLINEFORM0 ) is represented as a vector of real-valued features.\nWe defined the following feature sets:\nFS0: Baseline lexical features\nword uni-, bi-, and tri-grams (binary)\nFS1: Structural, morphological, and syntactic features\nFirst and last 3 tokens. Motivation: these tokens may contain discourse markers or other indicators for argument components, such as “therefore” and “since” for premises or “think” and “believe” for claims.\nRelative position in paragraph and relative position in document.

Motivation: Exploit the semantics of Capturing the semantics of the sentences.\nBinary features from Stanford Coreference Chain Resolver BIBREF118 , e.g., presence of the sentence in a chain, transition type (i.e., nominal–pronominal), distance to previous/next sentences in the chain, or number of inter-sentence coreference links. Motivation: Presence of coreference chains indicates links outside the sentence and thus may be informative, for example, for classifying whether the sentence is a part of a larger argument component.\nResults of a PTDB-style discourse parser BIBREF119 , namely the type of discourse relation (explicit, implicit), presence of discourse connectives, and attributions. Motivation: It has been claimed that discourse relations play a role in argumentation mining BIBREF120 .\nFS4: Embedding features\n300 features from word embedding vectors using word embeddings trained on part of the Google News dataset BIBREF121 . In particular, we sum up embedding vectors (dimensionality 300) of each word, resulting into a single vector for the entire sentence. This vector is then directly used as a feature vector. Motivation: Embeddings helped to achieve state-of-the-art results in various NLP tasks BIBREF116 , BIBREF122 .\nExcept the baseline lexical features, all feature types are extracted not only for the current sentence INLINEFORM0 , but also for INLINEFORM1 preceding and subsequent sentences, namely INLINEFORM2 , INLINEFORM3 , INLINEFORM4 INLINEFORM5 , INLINEFORM6 , where INLINEFORM7 was empirically set to 4. Each feature is then represented with a prefix to determine its relative position to the current sequence unit.\nLet us first discuss the upper bounds of the system. Performance of the three human annotators is shown in the first column of Table TABREF139 (results are obtained from a cumulative confusion matrix). The overall Macro- INLINEFORM0 score is 0.602 (accuracy 0.754). If we look closer at the different argument components, we observe that humans are good at predicting claims, premises, backing and non-argumentative text (about 0.60-0.80 INLINEFORM1 ), but on rebuttal and refutation they achieve rather low scores. Without these two components, the overall human Macro- INLINEFORM2 would be 0.707. This trend follows the inter-annotator agreement scores, as discussed in section UID75 .\nIn our experiments, the feature sets were combined in the bottom-up manner, starting with the simple lexical features (FS0), adding structural and syntactic features (FS1), then adding topic and sentiment features (FS2), then features reflecting the discourse structure (FS3), and finally enriched with completely unsupervised latent vector space representation (FS4). In addition, we were gradually removing the simple features (e.g., without lexical features, without syntactic features, etc.) to test the system with more “abstract” feature sets (feature ablation). The results are shown in Table TABREF139 .\nThe overall best performance (Macro- INLINEFORM0 0.251) was achieved using the rich feature sets (01234 and 234) and significantly outperformed the baseline as well as other feature sets. Classification of non-argumentative text (the \"O\" class) yields about 0.7 INLINEFORM1 score even in the baseline setting. The boundaries of claims (Cla-B), premises (Pre-B), and backing (Bac-B) reach in average lower scores then their respective inside tags (Cla-I, Pre-I, Bac-I). It can be interpreted such that the system is able to classify that a certain sentence belongs to a certain argument component, but the distinction whether it is a beginning of the argument component is harder. The very low numbers for rebuttal and refutation have two reasons. First, these two argument components caused many disagreements in the annotations, as discussed in section UID86 , and were hard to recognize for the humans too. Second, these four classes have very few instances in the corpus (about 3.4%, see Table TABREF114 ), so the classifier suffers from the lack of training data.\nThe results for the in-domain cross validation scenario are shown in Table TABREF140 . Similarly to the cross-validation scenario, the overall best results were achieved using the largest feature set (01234). For mainstreaming and red-shirting, the best results were achieved using only the feature set 4 (embeddings). These two domains contain also fewer documents, compared to other domains (refer to Table TABREF71 ). We suspect that embeddings-based features convey important information when not enough in-domain data are available. This observation will become apparent in the next experiment.\nThe cross-domain experiments yield rather poor results for most of the feature combinations (Table TABREF141 ). However, using only feature set 4 (embeddings), the system performance increases rapidly, so it is even comparable to numbers achieved in the in-domain scenario. These results indicate that embedding features generalize well across domains in our task of argument component identification. We leave investigating better performing vector representations, such as paragraph vectors BIBREF123 , for future work.\nError analysis based on the probabilistic confusion matrix BIBREF124 shown in Table TABREF142 reveals further details. About a half of the instances for each class are misclassified as non-argumentative (the \"O\" prediction).\nBacking-B is often confused with Premise-B (12%) and Backing-I with Premise-I (23%). Similarly, Premise-I is misclassified as Backing-I in 9%. This shows that distinguishing between backing and premises is not easy because these two components are similar such that they support the claim, as discussed in section UID86 . We can also see that the misclassification is consistent among *-B and *-I tags.\nRebuttal is often misclassified as Premise (28% for Rebuttal-I and 18% for Rebuttal-B; notice again the consistency in *-B and *-I tags). This is rather surprising, as one would expect that rebuttal would be confused with a claim, because its role is to provide an opposing view.\nRefutation-B and Refutation-I is misclassified as Premise-I in 19% and 27%, respectively. This finding confirms the discussion in section UID86 , because the role of refutation is highly context-dependent. In a pragmatic perspective, it is put forward to indirectly support the claim by attacking the rebuttal, thus having a similar function to the premise.\nWe manually examined miss-classified examples produced the best-performing system to find out which phenomena pose biggest challenges. Properly detecting boundaries of argument components caused problems, as shown in Figure FIGREF146 (a). This goes in line with the granularity annotation difficulties discussed in section UID86 . The next example in Figure FIGREF146 (b) shows that even if boundaries of components were detected precisely, the distinction between premise and backing fails. The example also shows that in some cases, labeling on clause level is required (left-hand side claim and premise) but the approximation in the system cannot cope with this level of detail (as explained in section UID111 ). Confusing non-argumentative text and argument components by the system is sometimes plausible, as is the case of the last rhetorical question in Figure FIGREF146 (c). On the other hand, the last example in Figure FIGREF146 (d) shows that some claims using figurative language were hard to be identified. The complete predictions along with the gold data are publicly available.\nSVMhmm offers many hyper-parameters with suggested default values, from which three are of importance. Parameter INLINEFORM0 sets the order of dependencies of transitions in HMM, parameter INLINEFORM1 sets the order of dependencies of emissions in HMM, and parameter INLINEFORM2 represents a trading-off slack versus magnitude of the weight-vector. For all experiments, we set all the hyper-parameters to their default values ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ). Using the best performing feature set from Table TABREF139 , we experimented with a grid search over different values ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) but the results did not outperform the system trained with default parameter values.\nThe INLINEFORM0 scores might seem very low at the first glance. One obvious reason is the actual performance of the system, which gives a plenty of room for improvement in the future. But the main cause of low INLINEFORM2 numbers is the evaluation measure — using 11 classes on the token level is very strict, as it penalizes a mismatch in argument component boundaries the same way as a wrongly predicted argument component type. Therefore we also report two another evaluation metrics that help to put our results into a context.\nKrippendorff's INLINEFORM0 — It was also used for evaluating inter-annotator agreement (see section UID75 ).\nBoundary similarity BIBREF125 — Using this metric, the problem is treated solely as a segmentation task without recognizing the argument component types.\nAs shown in Table TABREF157 (the Macro- INLINEFORM0 scores are repeated from Table TABREF139 ), the best-performing system achieves 0.30 score using Krippendorf's INLINEFORM1 , which is in the middle between the baseline and the human performance (0.48) but is considered as poor from the inter-annotator agreement point of view BIBREF54 . The boundary similarity metrics is not directly suitable for evaluating argument component classification, but reveals a sub-task of finding the component boundaries. The best system achieved 0.32 on this measure. Vovk2013MT used this measure to annotate argument spans and his annotators achieved 0.36 boundary similarity score. Human annotators in BIBREF125 reached 0.53 boundary similarity score.\nThe overall performance of the system is also affected by the accuracy of individual NPL tools used for extracting features. One particular problem is that the preprocessing models we rely on (POS, syntax, semantic roles, coreference, discourse; see section UID115 ) were trained on newswire corpora, so one has to expect performance drop when applied on user-generated content. This is however a well-known issue in NLP BIBREF126 , BIBREF127 , BIBREF128 .\nTo get an impression of the actual performance of the system on the data, we also provide the complete output of our best performing system in one PDF document together with the gold annotations in the logos dimension side by side in the accompanying software package. We believe this will help the community to see the strengths of our model as well as possible limitations of our current approaches.\nThese results indicate that embedding features generalize well across domains in our task of argument component identification.",

This is close to our model, although beyond a simple interpolation experiment (as in our sec:generating) they did not further explore the language vectors, which would have been challenging to do given the small number of languages used in their study.\nAmmar2016manylanguages used one-hot language identifiers as input to a multilingual word-based dependency parser, based on multilingual word embeddings.

        "answer": "It does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph.",
        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nHowever, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph.",

It lies 52 miles (83 km) northeast of Portland, Oregon, and 98 miles (158 km) south of Seattle. Mount St. Helens takes its English name from that of the British diplomat Lord St Helens, a friend of explorer George Vancouver who surveyed the area in the late 18th century. The volcano is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire.\n\nThe Mount St. Helens major eruption of May 18, 1980 remains the deadliest and most economically destructive volcanic event in U.S. history. Fifty-seven people were killed; 200 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche, triggered by a magnitude 5.1 earthquake, caused a lateral eruption that reduced the elevation of the mountain's summit from 9,677 ft (2,950 m) to 8,363 ft (2,549 m), leaving a 1 mile (1.6 km) wide horseshoe-shaped crater. The debris avalanche was 0.6 cubic miles (2.5 km3) in volume. The 1980 eruption disrupted terrestrial ecosystems near the volcano. By contrast, aquatic ecosystems in the area greatly benefited from the amounts of ash, allowing life to multiply rapidly. Six years after the eruption, most lakes in the area had returned to their normal state.\n\nAfter its 1980 eruption, the volcano experienced continuous volcanic activity until 2008. Geologists predict that future eruptions will be more destructive, as the configuration of the lava domes requires more pressure to erupt.

        "evidence": "The Avro Canada CF-105 Arrow was a delta-winged interceptor aircraft designed and built by Avro Canada. The CF-105 held the promise of Mach 2 speeds at altitudes exceeding 50,000 feet (15,000 m) and was intended to serve as the Royal Canadian Air Force's (RCAF) primary interceptor into the 1960s and beyond.\n\nThe Arrow was the culmination of a series of design studies begun in 1953 that examined improved versions of the Avro Canada CF-100 Canuck. After considerable study, the RCAF selected a dramatically more powerful design, and serious development began in March 1955. The aircraft was intended to be built directly from the production line, skipping the traditional hand-built prototype phase. The first Arrow Mk. 1, RL-201, was rolled out to the public on 4 October 1957, the same day as the launch of Sputnik I.\n\nFlight testing began with RL-201 on 25 March 1958, and the design quickly demonstrated excellent handling and overall performance, reaching Mach 1.9 in level flight. Powered by the Pratt & Whitney J75, another four Mk. 1s were completed, RL-202, RL-203, RL-204 and RL-205. The lighter and more powerful Orenda Iroquois engine was soon ready for testing, and the first Mk 2 with the Iroquois, RL-206, was ready for taxi testing in preparation for flight and acceptance tests by RCAF pilots by early 1959.",

For example, following the path that a decision tree takes to make its decision is trivial and self-explained, but following the paths of hundreds or thousands of trees is much harder. To achieve both performance and interpretability, some model compression techniques allow transforming an XGBoost into a single \"born-again\" decision tree that approximates the same decision function",

Schmidt in 1926. It is a variation of traditional Welsh rarebit and was one of two signature sandwiches created by chefs at the Brown Hotel shortly after its founding in 1923. It was created to serve as an alternative to ham and egg late-night dinners.\n\nIngredients\nThe Hot Brown is an open-faced sandwich of turkey breast and ham and bacon, covered in creamy Mornay sauce and baked or broiled until the bread is crisp and the sauce begins to brown. Cheddar cheese or American cheese may be added for the sauce. Alternatives for garnishes include tomatoes, mushroom slices, and, very rarely, canned peaches.\n\nSome Hot Browns also include ham with the turkey, and either pimentos or tomatoes over the sauce, and imitation Hot Browns sometimes substitute a commercial cheese sauce instead of the Mornay.\n\nWhen Fred K. Schmidt created the Hot Brown, its sliced roast turkey was a rarity, as turkey was usually reserved for holiday feasts. The original Hot Brown included the sliced turkey on an open-faced white toast sandwich, with Mornay sauce covering it, with a sprinkling of Parmesan cheese, completed by being oven-broiled until bubbly. Pimento and bacon strips were then added to it. After its debut, it quickly became the choice of 95% of the Brown Hotel's restaurant customers.\n\nThe dish is a local specialty and favorite of the Louisville area, and is popular throughout Kentucky.

Successfully understanding, participating or communicating with others in these situations presupposes some form of reasoning: about individual sentences, whole paragraphs of legal documents, small or bigger pieces of dialogue and so on. The human reasoning performed in these different situations cannot be explained by a single rigid system of reasoning, plainly because reasoning is performed in different ways in each one of them. Consider the following example:\nThree representatives are needed.\nIf a human reasoner with expert knowledge was to interpret the above utterance in a legal context, s/he will most probably judge that a situation where more than three references are provided could be compatible with the semantics of the utterance.

        "evidence": "Neural machine translation (NMT) BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 is a deep learning-based method for translation that has recently shown promising results as an alternative to statistical approaches. NMT systems directly model the probability of the next word in the target sentence simply by conditioning a recurrent neural network on the source sentence and previously generated target words.\nWhile both simple and surprisingly accurate, NMT systems typically need to have very high capacity in order to perform well: Sutskever2014 used a 4-layer LSTM with 1000 hidden units per layer (herein INLINEFORM0 ) and Zhou2016 obtained state-of-the-art results on English INLINEFORM1 French with a 16-layer LSTM with 512 units per layer. The sheer size of the models requires cutting-edge hardware for training and makes using the models on standard setups very challenging.\nThis issue of excessively large networks has been observed in several other domains, with much focus on fully-connected and convolutional networks for multi-class classification. Researchers have particularly noted that large networks seem to be necessary for training, but learn redundant representations in the process BIBREF6 . Therefore compressing deep models into smaller networks has been an active area of research. As deep learning systems obtain better results on NLP tasks, compression also becomes an important practical issue with applications such as running deep learning models for speech and translation locally on cell phones.\nExisting compression methods generally fall into two categories: (1) pruning and (2) knowledge distillation. Pruning methods BIBREF7 , BIBREF8 , BIBREF9 , zero-out weights or entire neurons based on an importance criterion: LeCun1990 use (a diagonal approximation to) the Hessian to identify weights whose removal minimally impacts the objective function, while Han2016 remove weights based on thresholding their absolute values. Knowledge distillation approaches BIBREF0 , BIBREF10 , BIBREF1 learn a smaller student network to mimic the original teacher network by minimizing the loss (typically INLINEFORM0 or cross-entropy) between the student and teacher output.\nIn this work, we investigate knowledge distillation in the context of neural machine translation. We note that NMT differs from previous work which has mainly explored non-recurrent models in the multi-class prediction setting. For NMT, while the model is trained on multi-class prediction at the word-level, it is tasked with predicting complete sequence outputs conditioned on previous decisions. With this difference in mind, we experiment with standard knowledge distillation for NMT and also propose two new versions of the approach that attempt to approximately match the sequence-level (as opposed to word-level) distribution of the teacher network. This sequence-level approximation leads to a simple training procedure wherein the student network is trained on a newly generated dataset that is the result of running beam search with the teacher network.\nWe run experiments to compress a large state-of-the-art INLINEFORM0 LSTM model, and find that with sequence-level knowledge distillation we are able to learn a INLINEFORM1 LSTM that roughly matches the performance of the full system. We see similar results compressing a INLINEFORM2 model down to INLINEFORM3 on a smaller data set. Furthermore, we observe that our proposed approach has other benefits, such as not requiring any beam search at test-time. As a result we are able to perform greedy decoding on the INLINEFORM4 model 10 times faster than beam search on the INLINEFORM5 model with comparable performance.

        "question": "How should I select a tennis racket if I'm completely new to the sport?",
        "evidence": "",
        "answer": "If you're a beginner tennis player, you should pick a racket that will help you learn the game quickly. There are a few key factors to consider. The first factor is grip size. There are several ways to measure grip size, but the simplest is to hold the grip and ensure there is about a finger's width remaining between your ring finger and base of your thumb when you hold the racket. Too small a grip may lead to squeezing the racket too hard, and too large a grip will make the racket unwieldy. The second factor is the weight of the racket. A racket in the range of 250 to 310 grams (unstrung) will be suitable for most players. A beginner male player might shoot for something in the 280-305 gram range, and a beginner female might use a racket in the 275-300 gram range. Junior players (age 10+), depending on age and size, should consider rackets in the 250 to 300 gram range. The third factor is the racket head size. You should look for a 100-105 square inch head size. These days even professionals use 100 sq inch commonly, and 95 is considered small (for advanced players). The racket composition is not a key differentiator, as most rackets are made of some sort of graphite composite material. Price is also not an indication of quality. Pricier rackets might be less suited to beginners, in fact. As to brand, it's a very personal choice. I would say choose a brand that you associate with wanting to play (perhaps you're a fan of a player who is sponsored by that brand). You can certainly find rackets at many big box retailers that would check all these boxes. And if you're not sure -- many online as well as local racket retailers run \"demo\" programs allowing you to try different rackets. Choose one that helps you consistently make contact with the ball and get it over the net. The most important thing is to get out on the court and play!",

It was created by French-Canadian Jesuit missionary priests in Canada, in the 17th Century.  The game of lacrosse is based on the traditional Native American game \"baggataway.\"'  This means \"little brother of war;\" it was also commonly referred to as \"The Creator's Game.\"  There are currently three predominant versions of lacrosse: Field Lacrosse, Box Lacrosse, and Women's Lacrosse.  \nField lacrosse is the men's outdoor version of the game.  There are 10 players on each team, on the field at once.  These players consist of 3 attackmen, 3 midfielders, 3 defensemen, and one goalie.  Each player has a helmet, shoulder pads, gloves, elbow pads, and a lacrosse stick.  6 players carry a short stick, which measures between 40 to 42 inches, and a maximum of four players on the field at a time can carry a long stick, which is between 52 and 72 inches long.  Short sticks are generally used by offensive players, and long sticks by defensive only players.  The goalie has a specific stick to his position, with a. wider \"head\" to assist in making saves.  The ball for play is made of solid rubber, about the size of a baseball.  A lacrosse goal measures 6 feet by 6 feet.  Teams are awarded one point for getting the ball into the goal.  \nEach game is 60 minutes long, made up of four 15 minute periods.  At the start of each period, and after ever goal, there is a face-off at the center of the field.  A unique aspect of lacrosse is that on a shot, when the ball goes out of bounds, possession is awarded to the team closet to the ball when it went out.  On out of bounds other than a shot attempt, possession is awarded to the opposite team that touched it last.  During the course of play teams may substitute players \"on the fly,\" through a designated substitution area (commonly referred to as \"the box\"), which is in between the benches of both teams.\nPenalties in lacrosse result from rule violations, deemed by either an infraction (commonly referred to as a \"technical foul\"), or a personal foul.  The result of the offending team is either losing possession of the ball, or temporarily losing a player for a designated period of time (similar to hockey).  The offending player serves their penalty in the box.  The team that has taken the penalty is the playing \"man-down\" for the time serving portion of the rule violation, while the other team is player \"man-up.\"\nThe generally consensus for who the greatest lacrosse player of all time is usually between three players: Jim Brown, Gary Gait, and John Grant.",

        "question": "Will the player be immediately rewarded after he/she lights the lamp in Zork1?",
        "answer": "No.",
        "evidence": "Many reinforcement learning algorithms are designed for relatively small discrete or continuous action spaces and so have trouble scaling. Text-adventure games—or interaction fictions—are simulations in which both an agents' state and action spaces are in textual natural language. An example of a one turn agent interaction in the popular text-game Zork1 can be seen in Fig. FIGREF1. Text-adventure games provide us with multiple challenges in the form of partial observability, commonsense reasoning, and a combinatorially-sized state-action space. Text-adventure games are structured as long puzzles or quests, interspersed with bottlenecks. The quests can usually be completed through multiple branching paths. However, games can also feature one or more bottlenecks. Bottlenecks are areas that an agent must pass through in order to progress to the next section of the game regardless of what path the agent has taken to complete that section of the quest BIBREF0. In this work, we focus on more effectively exploring this space and surpassing these bottlenecks—building on prior work that focuses on tackling the other problems.\nFormally, we use the definition of text-adventure games as seen in BIBREF1 and BIBREF2. These games are partially observable Markov decision processes (POMDPs), represented as a 7-tuple of $\\langle S,T,A,\\Omega , O,R, \\gamma \\rangle $ representing the set of environment states, mostly deterministic conditional transition probabilities between states, the vocabulary or words used to compose text commands, observations returned by the game, observation conditional probabilities, reward function, and the discount factor respectively. For our purposes, understanding the exact state and action spaces we use in this work is critical and so we define each of these in relative depth.\nAction-Space. To solve Zork1, the cannonical text-adventure games, requires the generation of actions consisting of up to five-words from a relatively modest vocabulary of 697 words recognized by the game’s parser. This results in $\\mathcal {O}(697^5)={1.64e14}$ possible actions at every step. To facilitate text-adventure game playing, BIBREF2 introduce Jericho, a framework for interacting with text-games. They propose a template-based action space in which the agent first selects a template, consisting of an action verb and preposition, and then filling that in with relevant entities $($e.g. $[get]$ $ [from] $ $)$. Zork1 has 237 templates, each with up to two blanks, yielding a template-action space of size $\\mathcal {O}(237 \\times 697^2)={1.15e8}$. This space is still far larger than most used by previous approaches applying reinforcement learning to text-based games.\nState-Representation. Prior work has shown that knowledge graphs are effective in terms of dealing with the challenges of partial observability $($BIBREF3 BIBREF3; BIBREF4$)$. A knowledge graph is a set of 3-tuples of the form $\\langle subject, relation, object \\rangle $. These triples are extracted from the observations using Stanford's Open Information Extraction (OpenIE) BIBREF5. Human-made text-adventure games often contain relatively complex semi-structured information that OpenIE is not designed to parse and so they add additional rules to ensure that the correct information is parsed. The graph itself is more or less a map of the world, with information about objects' affordances and attributes linked to the rooms that they are place in a map. The graph also makes a distinction with respect to items that are in the agent's possession or in their immediate surrounding environment. An example of what the knowledge graph looks like and specific implementation details can be found in Appendix SECREF14.\nBIBREF6 introduce the KG-A2C, which uses a knowledge graph based state-representation to aid in the section of actions in a combinatorially-sized action-space—specifically they use the knowledge graph to constrain the kinds of entities that can be filled in the blanks in the template action-space. They test their approach on Zork1, showing the combination of the knowledge graph and template action selection resulted in improvements over existing methods. They note that their approach reaches a score of 40 which corresponds to a bottleneck in Zork1 where the player is eaten by a “grue” (resulting in negative reward) if the player has not first lit a lamp. The lamp must be lit many steps after first being encountered, in a different section of the game; this action is necessary to continue exploring but doesn’t immediately produce any positive reward. That is, there is a long term dependency between actions that is not immediately rewarded, as seen in Figure FIGREF1. Others using artificially constrained action spaces also report an inability to pass through this bottleneck BIBREF7, BIBREF8. They pose a significant challenge for these methods because the agent does not see the correct action sequence to pass the bottleneck enough times. This is in part due to the fact that for that sequence to be reinforced, the agent needs to reach the next possible reward beyond the bottleneck.\nMore efficient exploration strategies are required to pass bottlenecks. Our contributions are two-fold. We first introduce a method that detects bottlenecks in text-games using the overall reward gained and the knowledge graph state. This method freezes the policy used to reach the bottleneck and restarts the training from there on out, additionally conducting a backtracking search to ensure that a sub-optimal policy has not been frozen. The second contribution explore how to leverage knowledge graphs to improve existing exploration algorithms for dealing with combinatorial action-spaces such as Go-Explore BIBREF9. We additionally present a comparative ablation study analyzing the performance of these methods on the popular text-game Zork1.\nThe lamp must be lit many steps after first being encountered, in a different section of the game; this action is necessary to continue exploring but doesnt immediately produce any positive reward.",

        "answer": "Strong winds driven, likely driven by climate change,  are posing new challenges to tree protection ordinances in northern California cities like Palo Alto, California. Climate change has caused stronger winds to occur in SF Bay Area. These strong gusts, some of which can be over 60 mph, are causing large, historic trees to fall onto houses threatening costly real estate as well as peoples lives. In the city of Palo Alto, California Oaks and Redwoods are classified as heritage trees. These majestic trees grow throughout the city and for many years have been vigilantly protected.  These trees are considered part of the city's unique character and history, therefore a part of its heritage.  Heritage trees cannot be cut down without the permission of a special city governance body and getting this okay to do so is very hard if not impossible to do.  The trees are beautiful and protecting them is noble, but  in the new era of unprecedented high winds some residents are asking if  their protection should be reconsidered given the risk they present to people and their homes during a storm. \n\nWhile storms are dramatic and do cause damage, they also occur infrequently and are a natural part of life.  Heritage oak and redwood trees which take hundreds of years to grow do pose some risks to homes and people should they fall, but overall they pose an insignificant risk to humans and buildings and need to continue to be protected in order to continue to provide their many benefits to humans.",

We built 16 models of word embeddings using the implementation of CBOW and Skip-gram methods in the FastText tool BIBREF9 .

The internal encoding solution based on embeddings of n-grams composing each word makes it possible to obtain FastText vector representations, also for words which were not processed during the creation of the model. A vector representation is associated with character n-gram and each word is represented as the sum of its n-gram vector representations. Previous solutions ignored the morphology of words and were assigning a distinct vector to each word. This is a limitation for languages with large vocabularies and many rare words, like Turkish, Finnish or Polish BIBREF9 . Authors observed that using word representations trained with subword information outperformed the plain Skip-gram model and the improvement was most significant for morphologically rich Slavic languages such as Czech (8% reduction of perplexity over SG) and Russian (13% reduction) BIBREF9 .

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nIn order to make the prediction model less biased to the speakers’ race and gender, we confine our analysis to the transcripts only.",

        "evidence": "To learn a policy for acting in the multi-agent SymmToM environment, it is a good strategy to use a multi-agent reinforcement learning algorithm. We use MADDPG, a wellknown multi-agent actor-critic framework with centralized planning and decentralized execution, to counter the non-stationarity nature of multi-agent settings. In MADDPG, each actor policy receives its observation space as input, and outputs the probability of taking each action.\nNotably, actors in MADDPG have no mechanism for remembering past turns. This is a critical issue in SymmToM, as agents cannot remember which pieces they currently know, which ones they shared and to whom, and other witnessed interactions. To mitigate this, it is necessary to add a recurrence mechanism to carry over information from past turns. One option would be to modify the agent policy using a recurrent network like an LSTM, as RMADDPG does.\nPerfect Information, Heuristic and Lower Bound Models Performance is difficult to interpret without simpler baselines. As a lower bound model we use the original MADDPG, that since it does not have recurrence embedded, should perform worse or equal to any of the modifications described above. We also include an oracle model (MADDPG-Oracle), that does not require theory of mind since it receives the current knowledge K for all agents in its observation space. The performance of MADDPG-Oracle may not always be achieved, as there could be unobserved communication with multiple situations happening with equal probability. Moreover, as the number of agents and size of the grid increases, current reinforcement learning models may not be able to find an optimal spatial exploration policy; they may also not be capable of inferring the optimal piece of information to communicate in larger settings. In these cases, MADDPG-Oracle may not perform optimally, so we also include a baseline with heuristic agents to compare performance. Heuristic agents will always move to the center of the board and communicate round-robin all the information pieces they know until they have all the available knowledge. Then, they will move efficiently to their recharge base and come back to the center of the grid, where the process restarts. We must mention that this heuristic is not necessarily the perfect policy, but it will serve as a baseline to note settings where current MARL models fail even with perfect information. Qualitatively, smaller settings have shown to approximately follow a policy like the heuristic just described.\nSymmToM is an environment where a agents are placed in a w × w grid world, and attempt to maximize their reward by gathering all the information available in the environment. There are c available information pieces, that each agent may or may not know initially. Information pieces known at the start of an episode are referred to as first-hand information. Each turn, agents may move through the grid to one of its four neighboring cells, and may speak exactly one of their currently known information pieces. More precisely, the action space of agent j is defined as follows:\nWhen an agent utters an information piece, it is heard by every agent in its hearing range (an h×h grid centered in each agent, with h < 2w − 1). The agents who heard the utterance will be able  to share this newly-learned information with others in following turns. We refer to this as secondhand information, since it is learned -as opposed to first-hand information, given at the start of each episode. The state space is comprised of the position of the agents and their current knowledge:\n. . , a}} where p i ∈ {1, . . . , w} × {1, . . . , w}, and\nEach agent aims to maximize their individual reward R i via information seeking and sharing. Rewards are earned by hearing a new piece of information, giving someone else a new piece of information, or correctly using recharge bases. Recharge bases are special cells where agents can reset their knowledge in exchange for a large reward (e.g. (n − 1)c times the reward for listening to or sharing new information). Each agent has its own stationary recharge base during an episode. To trigger a base, an agent must step into its designated base having acquired all the available pieces of information, causing the agent to lose all the second-hand information it learned. Recharge bases guarantee that there is always reward to seek in this environment. Concretely, if s = {(p i , k i ), for i ∈ {1, . . . , a}} and a i = (a dir i , a comm i ), we can define the reward as the addition of the reward for hearing new information, giving new information, and using the recharge base:\nA non-ToM agent can have only limited success in this environment. Without reasoning about its own knowledge (i.e. without zeroth order ToM), it does not know when to use a recharge base. Moreover, without knowledge about other agent's knowledge (i.e. without first order ToM) it is not possibly to know which agents possess the information pieces it is lacking. Even if it accidentally hears information, a non-first-order ToM agent cannot efficiently decide what to utter in response to maximize its reward. Higher order ToM is also often needed in SymmToM, as we will discuss further in Section 7.3.\nEven though we only discussed a collaborative task for SymmToM, it can easily be extended for competitive tasks. Moreover, all our models are also designed to work under competitive settings. SymmToM satisfies the desiderata we laid out in the previous section, as we will detail below: Symmetric action space. As defined in Eq. 1, A i = A j for all i, j. Only a subset may be available at a time since agents cannot step outside the grid, speak a piece they have not heard, or move if they would collide with another agent in the same cell, but they all share the same action space.\nImperfect information. Messages sent by agents outside of the hearing range will not be heard. For example, in Fig. green sends a message but it is not heard by anyone, since it is outside of red's and blue's range. Hearing ranges are guaranteed not to cover the whole grid, since h < 2w − 1.\nAgents have perfect vision of the grid, even if they cannot hear what was said outside of their hearing range. Hence, an agent may see that two agents were in range of each other, and thus probably interacted, but not hear what was communicated. An example of this can be seen in Fig., where green observes blue and red interacting without hearing what was uttered.\nThe uncertainty in the observation also differentiates SymmToM from prior work: to solve the task perfectly, an agent needs to assess the probability that other agents outside its hearing range shared a specific piece of information to avoid repetition. This estimation may be performed using the knowledge of what each agent knows (first order ToM), the perceived knowledge of each of the agents in the interaction (second order ToM), as well as higher order ToM.\nInformation-seeking behavior Rewards are explicitly given for hearing and sharing novel information, guaranteeing information-seeking is crucial in SymmToM. Recharge bases ensure that the optimal solution is not for all agents to accumulate in the same spot and quickly share all the information available; and that the information tracking required is more complex than accumulating past events. Conceptually, with recharge bases we introduce an explicit and observable forgetting mechanism. As discussed in Section 3, this allows for perpetual information seeking and requires information staleness estimation. An example of successful recharge base use is shown in Fig..\nWe use MADDPG (Lowe et al., 2017), a wellknown multi-agent actor-critic framework with centralized planning and decentralized execution, to counter the non-stationarity nature of multi-agent settings.****Even though we only discussed a collaborative task for SymmToM, it can easily be extended for competitive tasks. Moreover, all our models are also designed to work under competitive settings.",

        "question": "Given the reference text below, tell me when did the Seattle Seahawks win the Super Bowl, who they played against in the final game, and what was the final score.",
        "evidence": "In the 2013 NFL season, the Seahawks continued their momentum from the previous season, finishing tied with the Denver Broncos for an NFL-best regular season record of 13–3, while earning the NFC's #1 playoff seed. Their 2013 campaign included big wins over the Carolina Panthers, New Orleans Saints, and the San Francisco 49ers. Six Seahawks players were named to the Pro Bowl: Quarterback Russell Wilson, center Max Unger, running back Marshawn Lynch, cornerback Richard Sherman, free safety Earl Thomas, and strong safety Kam Chancellor. However, none of them were able to play in the Pro Bowl, as the Seahawks defeated the New Orleans Saints 23–15 and the San Francisco 49ers 23–17, in the playoffs to advance to Super Bowl XLVIII against the Denver Broncos. On February 2, 2014, the Seahawks won the franchise's only Super Bowl Championship, defeating Denver 43–8. The Seahawks' defense performance in 2013 was acclaimed as one of the best in the Super Bowl era.\n\n\nMarshawn Lynch scored on a 67-yard touchdown run in the NFC Wild-Card Playoff Game against the New Orleans Saints in 2011.\nThe 2014 campaign saw the team lose some key pieces, including wide receiver Golden Tate to free agency and wide receiver Sidney Rice and defensive end Chris Clemons to retirement. Percy Harvin was also let go mid-season after several underachieving weeks and clashes with the rest of the locker room. Despite starting 3–3, they rallied to a 12–4 record, good enough once again for the #1 seed in the NFC Playoffs. After dispatching the Carolina Panthers handily in the Divisional Round 31–17, they faced the Green Bay Packers in the NFC Championship Game. Despite five turnovers and trailing 19–7 late in the contest, the Seahawks prevailed in overtime to reach Super Bowl XLIX against New England Patriots, but an ill-fated interception at the 1-yard line late in the championship game stymied a comeback attempt and thwarted the Seahawks' bid to be the first repeat Super Bowl champions since the Patriots had won Super Bowls XXXVIII and XXXIX.\n\nThe Seahawks returned to the playoffs in both 2015 and 2016, but despite winning the Wild Card game in both years they failed to win either Divisional round game on the road. The 2017 iteration of the team missed the playoffs for the first time in six years, as injuries to their core players coupled with disappointing acquisitions of running back Eddie Lacy and kicker Blair Walsh failed them in a competitive NFC. The team cut ties with most of the remaining players that had been part of their meteoric rise and turnover both their Offensive and Defensive coaching staff in 2018, and an influx of young talent helped propel the team to a 10–6 record and another playoff berth that ultimately ended in a loss in the Wild Card game. In October 2018, owner Paul Allen died after a prolonged fight with cancer. In 2019, the Seahawks put up their best record since their last trip to the Super Bowl at 11–5, but they still lost 3 out of their last 4 games and lost their chance to win the NFC West. A likely explanation for their sloppy finish is because many of their players were injured late in the season. After defeating the Philadelphia Eagles 17–9 in the Wild Card game, they lost to the Green Bay Packers in the Divisional round, failing another attempt at a second Super Bowl.\n\nThe 2020 season saw the Seahawks win their first five games, a franchise-best for a start to a season. Despite the Seahawks losing three of their next four games, the Seahawks finished strong, earning twelve victories for the first time since their Super Bowl season in 2014, and winning the division for the first time in four years. However, despite the 12–4 record and the division title, the Seahawks' season ended the following week against the Rams, who never trailed in a 30–20 victory. The Seahawks struggled and started the 2021 season 3–8. Russell Wilson had an injured finger missing 3 games and the Seahawks were shut out the first time in the Wilson era in Week 10 against the Packers. This was their worst first half of a season since 2009, under then-head coach Jim Mora. The Seahawks were eliminated from playoff contention on December 26 in a loss to the Chicago Bears, and they finished last in their division for the first time since 1996. With wins over the Lions and the Cardinals they finished 7–10.\n\nFollowing the 2021 season was an off-season of continuing change, punctuated with the trade of quarterback Russell Wilson to the team he and the Seahawks beat in Super Bowl XLVIII, the Denver Broncos, on March 6, 2022. The Broncos traded quarterback Drew Lock, tight end Noah Fant, defensive lineman Shelby Harris, two first-round picks (for that year's draft, No. 9 overall, and 2023's), two second-round picks (that year's, No. 40 overall, and 2023's) and a 2022 fifth-round selection to the Seahawks for Wilson and a 2022 fourth-round pick. Another hallmark franchise player from the Super Bowl-winning Seahawks, former All-Pro linebacker Bobby Wagner, was also cut by the team that same day, a move that saves them $16.6 million in cap space. The Seahawks also took on $26 million in dead money by trading Wilson; ESPN Stats & Information research revealed it to be the second-most dead money a team has ever incurred, trailing the $33.8 million the Philadelphia Eagles ate in their trade of Carson Wentz the previous year.",

        "evidence": "Recently, text generation has been widely studied with neural models trained with maximum likelihood estimation BIBREF4 . However, MLE tends to generate universal text BIBREF18 . Various methods have been proposed to enhance the generation quality by refining the objective function BIBREF18 , BIBREF19 or modifying the generation distribution with external information like topic BIBREF20 , sentence type BIBREF21 , emotion BIBREF22 and knowledge BIBREF23 .\nAs mentioned above, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 . Thus, reinforcement learning has been introduced to text generation tasks such as policy gradient BIBREF6 and actor-critic BIBREF24 . BIBREF17 proposed an efficient and stable approach called Reward Augmented Maximum Likelihood (RAML), which connects the log-likelihood and expected rewards to incorporate MLE training objective into RL framework.\nSince some text generation tasks have no explicit metrics to be directly optimized, adversarial training has been applied to generating discrete text samples with a discriminator to learn a proper reward. For instance, SeqGAN BIBREF7 devised a discriminator to distinguish the real data and generated samples, and a generator to maximize the reward from the discriminator via policy gradient. Other variants of GANs have been proposed to improve the generator or the discriminator. To improve the generator, MaliGAN BIBREF8 developed a normalized maximum likelihood optimization target for the generator to stably model the discrete sequences. LeakGAN BIBREF11 guided the generator with reward signals leaked from the discriminator at all generation steps to deal with long text generation task. MaskGAN BIBREF10 employed an actor-critic architecture to make the generator fill in missing text conditioned on the surrounding context, which is expected to mitigate the problem of mode collapse. As for the discriminator, RankGAN BIBREF9 replaced traditional discriminator with a ranker to learn the relative ranking information between the real texts and generated ones. Inverse reinforcement learning BIBREF12 used a trainable reward approximator as the discriminator to provide dense reward signals at each generation step. DPGAN BIBREF13 introduced a language model based discriminator and regarded cross-entropy as rewards to promote the diversity of generation results.\nThe most similar works to our model are RAML BIBREF17 and MaliGAN BIBREF8 : 1) Compared with RAML, our model adds a discriminator to learn the reward signals instead of choosing existing metrics as rewards. We believe that our model can adapt to various text generation tasks, particularly those without explicit evaluation metrics. 2) Unlike MaliGAN, we acquire samples from a fixed distribution near the real data rather than the generator's distribution, which is expected to make the training process more stable.\nThe most similar works to our model are RAML (Norouzi et al., 2016) and MaliGAN (Che et al., 2017): 1) Compared with RAML, our model adds a discriminator to learn the reward signals instead of choosing existing metrics as rewards.

Every aspect of relocation needs to be planned keeping in mind the needs of each family member. Below are some experiences based on different criteria and considerations:\n\n1. City, area, zip: This is the primary decision that is made. It was also a function of the location that the underlying opportunity/job that triggers the relocation. In some cases, families might be returning. However, it is very important for one to research a city, area from multiple aspects before closing in or accepting the relocation. A right balance in terms of cons and pros can be ideal in selecting, since one may not find all requirements fulfilled in a particular location\n2. Cost of living/Inflation adjustment: Next is to test your selected area, zip, city with what you are going to earn from your primary business or job. Would you be able to maintain, if not improve your current standard of living. More importantly, with a family it is critical that you are also able to save a monthly sum towards health, education, etc for the future.\n3. Schooling: The education system across countries are very different. There are concepts of public, charter schools that exist in some locations, but they may be either not be par with quality you would expect or not exist at all. The education board options also make it complex, which requires one to make a choice based on their own preferences and ideology.  The third factor is the variation in teaching methodology, example Montessori.\n4. Healthcare: Identify primary health care providers soon, share medical records from the past and have the kids up to date on vaccination. There might be scenarios where one may have to re-vaccinate kids based on schooling requirement.\n4. Surrounding ecosystem: Once the initial items are done, identify good places for leisure, fun and family time. Example, sports classes for kids, art classes, theatres, parks, beaches, weekend getaways, etc. These are the places that will give the time to bond after a long transition, plus also enjoy the new location.",

Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW.

At the club level, he was Santos's all-time top goalscorer with 643 goals in 659 games. In a golden era for Santos, he led the club to the 1962 and 1963 Copa Libertadores, and to the 1962 and 1963 Intercontinental Cup. Credited with connecting the phrase \"The Beautiful Game\" with football, Pelé's \"electrifying play and penchant for spectacular goals\" made him a star around the world, and his teams toured internationally to take full advantage of his popularity. During his playing days, Pelé was for a period the best-paid athlete in the world. After retiring in 1977, Pelé was a worldwide ambassador for football and made many acting and commercial ventures. In 2010, he was named the honorary president of the New York Cosmos.\n\nAveraging almost a goal per game throughout his career, Pelé was adept at striking the ball with either foot in addition to anticipating his opponents' movements on the field. While predominantly a striker, he could also drop deep and take on a playmaking role, providing assists with his vision and passing ability, and he would also use his dribbling skills to go past opponents. In Brazil, he was hailed as a national hero for his accomplishments in football and for his outspoken support of policies that improve the social conditions of the poor. His emergence at the 1958 World Cup, where he became a black global sporting star, was a source of inspiration. Throughout his career and in his retirement, Pelé received numerous individual and team awards for his performance on the field, his record-breaking achievements, and his legacy in the sport.\n\nEarly years\n\nBorn in Três Corações in Minas Gerais state in Brazil in 1940, Pelé has a street named after him in the city – Rua Edson Arantes do Nascimento. A statue of Pelé is also prominently placed in a plaza near the city's downtown.\nPelé was born Edson Arantes do Nascimento on 23 October 1940 in Três Corações, Minas Gerais, the son of Fluminense footballer Dondinho (born João Ramos do Nascimento) and Celeste Arantes. He was the elder of two siblings, with brother Zoca also playing for Santos, albeit not as successfully. He was named after the American inventor Thomas Edison. His parents decided to remove the \"i\" and call him \"Edson\", but there was a typo on his birth certificate, leading many documents to show his name as \"Edison\", not \"Edson\", as he was called. He was originally nicknamed \"Dico\" by his family. He received the nickname \"Pelé\" during his school days, when, it is claimed, he was given it because of his pronunciation of the name of his favourite player, local Vasco da Gama goalkeeper Bilé, which he misspoke, but the more he complained the more it stuck. In his autobiography released in 2006, Pelé stated he had no idea what the name means, nor did his old friends. Apart from the assertion that the name is derived from that of \"Bilé\", the word has no meaning in Portuguese.[note 2]\n\nPelé grew up in poverty in Bauru in the state of São Paulo. He earned extra money by working in tea shops as a servant. Taught to play by his father, he could not afford a proper football and usually played with either a sock stuffed with newspaper and tied with string or a grapefruit. He played for several amateur teams in his youth, including Sete de Setembro, Canto do Rio, São Paulinho, and Ameriquinha. Pelé led Bauru Atlético Clube juniors (coached by Waldemar de Brito) to two São Paulo state youth championships. In his mid-teens, he played for an indoor football team called Radium. Indoor football had just become popular in Bauru when Pelé began playing it. He was part of the first futsal (indoor football) competition in the region. Pelé and his team won the first championship and several others.\n\nAccording to Pelé, futsal (indoor football) presented difficult challenges: he said it was a lot quicker than football on the grass, and that players were required to think faster because everyone is close to each other in the pitch. Pelé credits futsal for helping him think better on the spot. In addition, futsal allowed him to play with adults when he was about 14 years old. In one of the tournaments he participated in, he was initially considered too young to play, but eventually went on to end up top scorer with 14 or 15 goals. \"That gave me a lot of confidence\", Pelé said, \"I knew then not to be afraid of whatever might come\".\n\nClub career\nSantos\nMain article: Os Santásticos\n1956–1962: Early years with Santos and declared a national treasure\n\nPelé in 1962, by then rated the best player in the world\nIn 1956, de Brito took Pelé to Santos, an industrial and port city located near São Paulo, to try out for professional club Santos FC, telling the club's directors that the 15-year-old would be \"the greatest football player in the world.\" Pelé impressed Santos coach Lula during his trial at the Estádio Vila Belmiro, and he signed a professional contract with the club in June 1956. Pelé was highly promoted in the local media as a future superstar. He made his senior team debut on 7 September 1956 at the age of 15 against Corinthians de Santo André and had an impressive performance in a 7–1 victory, scoring the first goal in his prolific career during the match.\n\nWhen the 1957 season started, Pelé was given a starting place in the first team and, at the age of 16, became the top scorer in the league. Ten months after signing professionally, the teenager was called up to the Brazil national team. After the 1958 and the 1962 World Cup, wealthy European clubs, such as Real Madrid, Juventus and Manchester United, tried to sign him in vain. In 1958, Inter Milan even managed to get him a regular contract, but Angelo Moratti was forced to tear the contract up at the request of Santos's chairman following a revolt by Santos's Brazilian fans. Valencia CF also arranged an agreement that would have brought Pelé to the club after the 1958 World Cup, however after his performances at the tournament Santos declined to let the player leave. In 1961 the government of Brazil under President Jânio Quadros declared Pelé an \"official national treasure\" to prevent him from being transferred out of the country.\n\nPelé won his first major title with Santos in 1958 as the team won the Campeonato Paulista; he would finish the tournament as the top scorer, with 58 goals, a record that still stands today. A year later, he would help the team earn their first victory in the Torneio Rio-São Paulo with a 3–0 over Vasco da Gama. However, Santos was unable to retain the Paulista title. In 1960, Pelé scored 33 goals to help his team regain the Campeonato Paulista trophy but lost out on the Rio-São Paulo tournament after finishing in 8th place. In the 1960 season, Pelé scored 47 goals and helped Santos regain the Campeonato Paulista. The club went on to win the Taça Brasil that same year, beating Bahia in the finals; Pelé finished as the top scorer of the tournament with nine goals. The victory allowed Santos to participate in the Copa Libertadores, the most prestigious club tournament in the Western hemisphere.\n\n1962–1965: Copa Libertadores success\n\"I arrived hoping to stop a great man, but I went away convinced I had been undone by someone who was not born on the same planet as the rest of us.\"\n\n—Benfica goalkeeper Costa Pereira following the loss to Santos in 1962.\nSantos's most successful Copa Libertadores season started in 1962; the team was seeded in Group One alongside Cerro Porteño and Deportivo Municipal Bolivia, winning every match of their group but one (a 1–1 away tie versus Cerro). Santos defeated Universidad Católica in the semi-finals and met defending champions Peñarol in the finals. Pelé scored twice in the playoff match to secure the first title for a Brazilian club. Pelé finished as the second top scorer of the competition with four goals. That same year, Santos would successfully defend the Campeonato Paulista (with 37 goals from Pelé) and the Taça Brasil (Pelé scoring four goals in the final series against Botafogo). Santos would also win the 1962 Intercontinental Cup against Benfica. Wearing his number 10 shirt, Pelé produced one of the best performances of his career, scoring a hat-trick in Lisbon as Santos won 5–2.\n\n\nPelé with Santos in the Netherlands, October 1962\nPelé states that his most memorable goal was scored at the Estádio Rua Javari on a Campeonato Paulista match against São Paulo rival Clube Atlético Juventus on 2 August 1959. As there is no video footage of this match, Pelé asked that a computer animation be made of this specific goal. In March 1961, Pelé scored the gol de placa (goal worthy of a plaque), against Fluminense at the Maracanã. Pelé received the ball on the edge of his own penalty area, and ran the length of the field, eluding opposition players with feints, before striking the ball beyond the goalkeeper. A plaque was commissioned with a dedication to \"the most beautiful goal in the history of the Maracanã\".\n\n\nPelé before facing Boca Juniors in the second leg of the 1963 Copa Libertadores Finals at La Bombonera.\nAs the defending champions, Santos qualified automatically to the semi-final stage of the 1963 Copa Libertadores. The balé branco (white ballet), the nickname given to Santos at the time, managed to retain the title after victories over Botafogo and Boca Juniors. Pelé helped Santos overcome a Botafogo team that featured Brazilian greats such as Garrincha and Jairzinho with a last-minute goal in the first leg of the semi-finals which made it 1–1. In the second leg, Pelé scored a hat-trick in the Estádio do Maracanã as Santos won, 0–4, in the second leg. Santos started the final series by winning, 3–2, in the first leg and defeating Boca Juniors 1–2, in La Bombonera. It was a rare feat in official competitions, with another goal from Pelé. Santos became the first Brazilian team to lift the Copa Libertadores in Argentine soil. Pelé finished the tournament with five goals. Santos lost the Campeonato Paulista after finishing in third place but went on to win the Rio-São Paulo tournament after a 0–3 win over Flamengo in the final, with Pelé scoring one goal. Pelé would also help Santos retain the Intercontinental Cup and the Taça Brasil against AC Milan and Bahia respectively.\n\nIn the 1964 Copa Libertadores, Santos was beaten in both legs of the semi-finals by Independiente. The club won the Campeonato Paulista, with Pelé netting 34 goals. Santos also shared the Rio-São Paulo title with Botafogo and won the Taça Brasil for the fourth consecutive year. In the 1965 Copa Libertadores, Santos reached the semi-finals and met Peñarol in a rematch of the 1962 final. After two matches, a playoff was needed to break the tie. Unlike 1962, Peñarol came out on top and eliminated Santos 2–1. Pelé would, however, finish as the top scorer of the tournament with eight goals.\n\n1966–1974: O Milésimo and final years with Santos\nIn 1966, Santos failed to retain the Taça Brasil as Pelé's goals were not enough to prevent a 9–4 defeat by Cruzeiro (led by Tostão) in the final series. The club did, however, win the Campeonato Paulista in 1967, 1968, and 1969. On 19 November 1969, Pelé scored his 1,000th goal in all competitions, in what was a highly anticipated moment in Brazil. The goal dubbed O Milésimo (The Thousandth), occurred in a match against Vasco da Gama, when Pelé scored from a penalty kick, at the Maracanã Stadium.\n\nIn 1969, the two factions involved in the Nigerian Civil War agreed to a 48-hour ceasefire so they could watch Pelé play an exhibition game in Lagos. Santos ended up playing to a 2–2 draw with Lagos side Stationary Stores FC and Pelé scored his team's goals. The civil war went on for one more year after this game. During his time at Santos, Pelé played alongside many gifted players, including Zito, Pepe, and Coutinho; the latter partnered him in numerous one-two plays, attacks, and goals. After Pelé's 19th season with Santos, he left Brazilian football. Pelé's 643 goals for Santos were the most goals scored for a single club until it was surpassed by Lionel Messi of Barcelona in December 2020.\n\nNew York Cosmos\n\nPelé signing a football for US president Richard Nixon at the White House in 1973, two years before joining the New York Cosmos\nAfter the 1974 season (his 19th with Santos), Pelé retired from Brazilian club football although he continued to occasionally play for Santos in official competitive matches. A year later, he came out of semi-retirement to sign with the New York Cosmos of the North American Soccer League (NASL) for the 1975 season. At a chaotic press conference at New York's 21 Club, the Cosmos unveiled Pelé. John O'Reilly, the club's media spokesman, stated, \"We had superstars in the United States but nothing at the level of Pelé. Everyone wanted to touch him, shake his hand, get a photo with him.\" Though well past his prime at this point, Pelé was credited with significantly increasing public awareness and interest of the sport in the US. During his first public appearance in Boston, he was injured by a crowd of fans who had surrounded him and was evacuated on a stretcher.\n\n\nPelé entering the field to play his first game with the Cosmos, 15 June 1975\nPelé made his debut for the Cosmos on 15 June 1975 against the Dallas Tornado at Downing Stadium, scoring one goal in a 2–2 draw. Pelé opened the door for many other stars to play in North America. Giorgio Chinaglia followed him to the Cosmos, then Franz Beckenbauer and his former Santos teammate Carlos Alberto. Over the next few years other players came to the league, including Johan Cruyff, Eusébio, Bobby Moore, George Best and Gordon Banks.\n\nIn 1975, one week before the Lebanese Civil War, Pelé played a friendly game for the Lebanese club Nejmeh against a team of Lebanese Premier League stars, scoring two goals which were not included in his official tally. On the day of the game, 40,000 spectators were at the stadium from early morning to watch the match.\n\nPelé led the Cosmos to the 1977 Soccer Bowl, in his third and final season with the club. In June 1977, the Cosmos attracted an NASL record 62,394 fans to Giants Stadium for a 3–0 victory past the Tampa Bay Rowdies with a 37-year-old Pelé scoring a hat-trick. In the first leg of the quarter-finals, they attracted a US record crowd of 77,891 for what turned into an 8–3 rout of the Fort Lauderdale Strikers at Giants Stadium. In the second leg of the semi-finals against the Rochester Lancers, the Cosmos won 4–1. Pelé finished his official playing career on 28 August 1977, by leading the New York Cosmos to their second Soccer Bowl title with a 2–1 win over the Seattle Sounders at the Civic Stadium in Portland, Oregon.\n\nOn 1 October 1977, Pelé closed out his career in an exhibition match between the Cosmos and Santos. The match was played in front of a sold-out crowd at Giants Stadium and was televised in the US on ABC's Wide World of Sports as well as throughout the world. Pelé's father and wife both attended the match, as well as Muhammad Ali and Bobby Moore. Delivering a message to the audience before the start of the game—\"Love is more important than what we can take in life\"—Pelé played the first half with the Cosmos, the second with Santos. The game ended with the Cosmos winning 2–1, with Pelé scoring with a 30-yard free-kick for the Cosmos in what was the final goal of his career. During the second half, it started to rain, prompting a Brazilian newspaper to come out with the headline the following day: \"Even The Sky Was Crying.\"",

        "answer": "The process by which they identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc.",
        "evidence": "Named entity recognition (NER) BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc. NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction BIBREF4 , machine translation BIBREF5 , question answering BIBREF6 and knowledge base construction BIBREF7 . Although early NER systems have been successful in producing adequate recognition accuracy, they often require significant human effort in carefully designing rules or features.\nIn recent years, deep learning methods been employed in NER systems, yielding state-of-the-art performance. However, the number of types detected are still not sufficient for certain domain-specific applications. For relation extraction, identifying fine-grained types has been shown to significantly increase the performance of the extractor BIBREF8 , BIBREF9 since this helps in filtering out candidate relation types which do not follow this type constraint. Furthermore, for question answering fine-grained Named Entity Recognition (FgNER) can provide additional information helping to match questions to its potential answers thus improving performance BIBREF10 . For example, Li and Roth BIBREF11 rank questions based on their expected answer types (i.e. will the answer be food, vehicle or disease).\nTypically, FgNER systems use over a hundred labels, arranged in a hierarchical structure. We find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process. Furthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task. Currently, FgNER systems use distant supervision BIBREF12 to automatically generate training data. Distant supervision is a technique which maps each entity in the corpus to knowledge bases such as Freebase BIBREF13 , DBpedia BIBREF14 , YAGO BIBREF15 and helps with the generation of labeled data. This method will assign the same set of labels to all mentions of a particular entity in the corpus. For example, “Barack Obama” is a person, politician, lawyer, and author. If a knowledge base has these four matching labels, the distant supervision technique will assign all of them to every mention of “Barack Obama”. Therefore, the training data will also fail to distinguish between mentions of “Barack Obama” in all subsequent utterances.\nLing et al. ling2012fine proposed the first system for FgNER, where they used 112 overlapping labels with a linear classifier perceptron for multi-label classification. Yosef et al. spaniol2012hyena used multiple binary SVM classifiers to assign entities to a set of 505 types. Gillick et al. gillick2014context introduced context dependent FgNER and proposed a set of heuristics for pruning labels that might not be relevant given the local context of the entity. Yogatama et al. yogatama2015embedding proposed an embedding based model where user-defined features and labels were embedded into a low dimensional feature space to facilitate information sharing among labels.\nShimaoka et al. shimaoka2016attentive proposed an attentive neural network model which used long short-term memory (LSTMs) to encode the context of the entity, then used an attention mechanism to allow the model to focus on relevant expressions in the entity mention's context. To learn entity representations, we propose a scheme which is potentially more generalizable.\nNamed entity recognition (NER) (Collins and Singer, 1999; Tjong Kim Sang and De Meul der, 2003; Ratinov and Roth, 2009; Manning et al., 2014) is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc.",

Next, we clamped the role labels of the supervised sentences using the predefined mapping from Section SECREF29 . Sampling was done on the unsupervised sentences as usual. We then measured the clustering performance using the trained parameters.\nTo access the contribution of partial supervision better, we constructed a “supervised baseline” as follows. For predicates seen in the supervised sentences, a MAP estimate of the parameters was calculated using the predefined mapping. For the unseen predicates, the standard baseline was used.\nFigures FIGREF33 and FIGREF33 show the performance variation with INLINEFORM0 . We make the following observations:\n[leftmargin=*]\nIn both languages, at around INLINEFORM0 , the supervised baseline starts outperforming the semi-supervised model, which suggests that manually labeling about 10% of the sentences is a good enough alternative to our training procedure. Note that 10% amounts to about 3.6k sentences in German and 4k in English. We noticed that the proportion of seen predicates increases dramatically as we increase the proportion of supervised sentences. At 10% supervised sentences, the model has already seen 63% of predicates in German and 44% in English. This explains to some extent why only 10% labeled sentences are enough.\nFor German, it takes about 3.5% or 1260 supervised sentences to have the same performance increase as 1.5M unlabeled sentences (Line 1 to Line 2 in Table TABREF27 ). Adding about 180 more supervised sentences also covers the benefit obtained by alignments in the multilingual model (Line 2 to Line 3 in Table TABREF27 ). There is no noticeable performance difference in English.\nWe also evaluated the performance variation on a completely unseen CoNLL test set.

        "answer": "Surfing in San Francisco can be challenging. It's cold, rocky and the conditions are often unforgiving. That doesn't mean there isn't great surf in the area. Here are a few fun spots.  \nStarting in Marin County, you can’t ignore a small town called Bolinas. Bolinas has prided itself on its efforts to stay off the grid. Unfortunately, COVID has brought a lot more people out of the city and bolinas isn’t the secret spot it used to be.  Bolinas is a coastal town in West Marin that has managed to protect itself from big city life. The locals there love keeping Bolinas off the grid. Traveling to Bolinas feels like you’ve went back in time 50 years. In a good way. Bolinas offers a few spots to surf but is generally a longboard wave and is best on incoming mid to high tide. Be respectful of the locals there and the life they’ve carved out for themselves. \n\nAfter Bolinas you can head south and just north of the Golden Gate Bridge. Ft Cronkite is a nestled in the Marin Headlands. The beach there is called Rodeo Beach. There is a small parking lot at the beach which hosts many hikers and cyclists as well. The beach is a little cove that is generally protected from the wind. So, when other surf spots in the area may be messy and wind blown, Ft Cron could be clean and protected. This wave is finicky though. It is a bit hit or miss and is a tough wave to surf. I would categorize it for the intermediate to advanced surfer and you need to catch it at mid to high tide.\n\nThe next spot to go is Ft. Point. Head south over the Golden Gate Bridge. Surfing Ft. Point is really a novalty. It is a left that is tucked under the Golden Gate Bridge. It rarely breaks big enough to surf, but when it does, it is worth paddling out just to say you surfed under the Golden Gate. If you're lucky enough to enjoy this wave when it's breaking be sure to get some photos to prove it. \n\nJust south a few minutes from Ft. Point is Ocean Beach. Ocean Beach is a large beach break where the city of San Francisco hits the Pacific Ocean. This wave is documented as one of the roughest beach breaks to surf. The paddle out is long. Ocean Beach is not for the faint of heart. The current is strong. When Ocean Beach is going well (generally in the winter), it gets really good. Double overhead barrels good. \n\nIf Ocean Beach is a bit too heavy for you, it's easy to head south a tad to Pacifica State Beach at Linda Mar. Linda Mar is a little beach break that is learner and local friendly. The crowds can get big here because there are so many beginner surfers at this spot. \n\nThere are plenty more spots to surf in the Bay Area. These are just a few of the best spots to go. Enjoy the Bay Area surfing.",

        "evidence": "Dictionaries are frequently used to code texts in content analyses BIBREF37 . Dictionaries consist of one or more categories (i.e. word lists). Sometimes the output is simply the number of category occurrences (e.g., positive sentiment), thus weighting words within a category equally. In some other cases, words are assigned continuous scores. The high transparency of dictionaries makes them sometimes more suitable than supervised machine learning models. However, dictionaries should only be used if the scores assigned to words match how the words are used in the data (see BIBREF38 for a detailed discussion on limitations). There are many off-the-shelf dictionaries available (e.g., LIWC BIBREF39 ). These are often well-validated, but applying them on a new domain may not be appropriate without additional validation. Corpus- or domain-specific dictionaries can overcome limitations of general-purpose dictionaries.\nThe dictionaries are often manually compiled, but increasingly they are constructed semi-automatically (e.g., BIBREF40 ). When we semi-automatically create a word list, we use automation to identify an initial word list, and human insight to filter it. By automatically generating the initial words lists, words can be identified that human annotators might have difficulty intuiting. By manually filtering the lists, we use our theoretical understanding of the target concept to remove spurious features.\nIn the introduction study, SAGE BIBREF41 was used to obtain a list of words that distinguished the text in the treatment group (subreddits that were closed by Reddit) from text in the control group (similar subreddits that were not closed). The researchers then returned to the hate speech definition provided by the European Court of Human Rights, and manually filtered the top SAGE words based on this definition. Not all identified words fitted the definition. The others included: the names of the subreddits themselves, names of related subreddits, community-specific jargon that was not directly related to hate speech, and terms such as IQ and welfare, which were frequently used in discourses of hate speech, but had significant other uses. The word lists provided the measurement instrument for their main result, which is that the use of hate speech throughout Reddit declined after the two treatment subreddits were closed.\nThe researchers then returned to the hate speech definition provided by the European Court of Human Rights, and manually filtered the top SAGE words based on this definition.",

Typically, this dish is extremely spicy and loaded with garlic. The royals and rajputs love this meal very much.\n\nDal Bati with Churma: This is Rajasthan's most well-known dish. Lentils are known as dal, baked wheat balls are known as bati, and sweetened cereal is known as churma. Popular churma is typically served with baatis and dal.

Bottleneck memory consumption is the maximum memory consumption recorded when running the methods. For evaluation, we ran each method on a machine equipped with two Intel(R) Xeon(R) CPU E5-2667 v4 and one NVIDIA Tesla K80.\nProcess times per update (numbers in parentheses in Table) indicate that DroQ runs more than two times faster than REDQ. DroQ (and SAC) requires process times in the 800-900-msec range. REDQ requires process times in the 2200-2300-msec range. Process times also show that learning Q-functions is dominant in an overall loop. This suggests that using compact (e.g., small numbers of) Q-functions is important for improving overall process times.\nThe number of parameters and bottleneck memory consumption of each method indicate that DroQ is more memory efficient than REDQ. Regarding the numbers of parameters (Table), we can see that those of DroQ (and SAC and DUVN) are about one-fifth those of REDQ. Note that the number of parameters of DroQ is equal to that of SAC since DroQ and SAC use the same number (two) of Q-functions. Regarding the bottleneck memory consumption (Table), we can see that that for DroQ (SAC and DUVN) is about one-third that for REDQ. We can also see that the bottleneck Figure: Average return and average/standard deviation of estimation bias for REDQ, SAC, DUVN, and DroQ.

        "answer": "The greatest soccer players of all time is a widely debated question and is subject to one's personal opinions and values. Here is a list of soccer players who are commonly thought of as some of the greatest of all time:\n\n1. Pelé from Brazil, who played from 1956 to 1977, is widely considered as one of the greatest soccer players of all time due to his prolific goal-scoring, and 3 world cup titles. His 1279 goals including friendlies is recognized as a Guinness World Record. In 1999 he was named the Athlete of the Century by the International Olympic Committee. \n2. Johann Cruyff from the Netherlands, who played from 1964-1984, is considered by many to be of the greatest players of all time winning the Ballon'dOr 3 times and leading the Netherlands to the world cup final in 1974 where he received the Golden Ball as the player of the tournament. In 1999 he was voted European Player of the Century and came second behind Pelé as world player of the Century.\n3. Diego Maradona from Argentina, who played from 1976 to 1997, is widely considered one of the greatest soccer players of all time due to his passing, vision, and ball control as well as his leadership on the field. Maradona scored the goal of the century in 1986 with an incredible solo goal as he dribbled 60 meters past 5 England defenders.\n4. Cristiano Ronaldo, who played from 2002 to current, is widely considered by many one of the greatest soccer players of all time. Known for his prolific goal-scoring on a variety of different teams and in a variety of different ways Ronaldo is thought of by many as the 'Complete Player'. He has won the Ballon d'Or 5 times and currently holds the all-time record for most men's international goals (122), most goals in the champions league (140), and the most professional goals (834).\n5. Lionel Messi, who played from 2003 to current, is widely considered by many as one of the greatest soccer players of all time. Known by many as the magician, Messi is known for his vision, passing, and tight ball control. Messi has won a record 7 Ballon d'Or awards, the most goals in La Liga (484), the most hat tricks in La Liga (34), and the most assists in La Liga (192). Messi also lead Argentian to win the 2022 World Cup in Qatar which many believe cemented his place as one of the all-time greats.",

        "question": "Which model is superior, ToBERT or RoBERT?",
        "answer": "ToBERT.",
        "evidence": "Table TABREF25 presents results using pre-trained BERT features. We extracted features from the pooled output of final transformer block as these were shown to be working well for most of the tasks BIBREF1. The features extracted from a pre-trained BERT model without any fine-tuning lead to a sub-par performance. However, We also notice that ToBERT model exploited the pre-trained BERT features better than RoBERT. It also converged faster than RoBERT. Table TABREF26 shows results using features extracted after fine-tuning BERT model with our datasets. Significant improvements can be observed compared to using pre-trained BERT features. Also, it can be noticed that ToBERT outperforms RoBERT on Fisher and 20newsgroups dataset by 13.63% and 0.81% respectively. On CSAT, ToBERT performs slightly worse than RoBERT but it is not statistically significant as this dataset is small.\nTable TABREF27 presents results using fine-tuned BERT predictions instead of the pooled output from final transformer block. For each document, having obtained segment-wise predictions we can obtain final prediction for the whole document in three ways:\nCompute the average of all segment-wise predictions and find the most probable class;\nFind the most frequently predicted class;\nTrain a classification model.\nIt can be observed from Table TABREF27 that a simple averaging operation or taking most frequent predicted class works competitively for CSAT and 20newsgroups but not for the Fisher dataset. We believe the improvements from using RoBERT or ToBERT, compared to simple averaging or most frequent operations, are proportional to the fraction of long documents in the dataset. CSAT and 20newsgroups have (on average) significantly shorter documents than Fisher, as seen in Fig. FIGREF21. Also, significant improvements for Fisher could be because of less confident predictions from BERT model as this dataset has 40 classes. Fig. FIGREF31 presents the comparison of average voting and ToBERT for various document length ranges for Fisher dataset. We used fine-tuned BERT segment-level predictions (P) for this analysis. It can be observed that ToBERT outperforms average voting in every interval. To the best of our knowledge, this is a state-of-the-art result reported on the Fisher dataset.\nTable TABREF32 presents the effect of position embeddings on the model performance. It can be observed that position embeddings did not significantly affect the model performance for Fisher and 20newsgroups, but they helped slightly in CSAT prediction (an absolute improvement of 0.64% F1-score). We think that this is explained by the fact that Fisher and 20newsgroups are topic identification tasks, and the topic does not change much throughout these documents. However, CSAT may vary during the call, and in some cases a naive assumption that the sequential nature of the transcripts is irrelevant may lead to wrong conclusions.\nTable TABREF33 compares our results with previous works. It can be seen that our model ToBERT outperforms CNN based experiments by significant margin on CSAT and Fisher datasets. For CSAT dataset, we used multi-scale CNN (MS-CNN) as the baseline, given its strong results on Fisher and 20newsgroups. The setup was replicated from BIBREF5 for comparison. We also see that our result on 20 newsgroups is 0.6% worse than the state-of-the-art.\nWe also notice that ToBERT model exploited the pre-trained BERT features better than RoBERT.

        "evidence": "With the availability of rich data on users' locations, profiles and search history, personalization has become the leading trend in large-scale information retrieval. However, efficiency through personalization is not yet the most suitable model when tackling domain-specific searches. This is due to several factors, such as the lexical and semantic challenges of domain-specific data that often include advanced argumentation and complex contextual information, the higher sparseness of relevant information sources, and the more pronounced lack of similarities between users' searches.\nA recent study on expert search strategies among healthcare information professionals BIBREF0 showed that, for a given search task, they spend an average of 60 minutes per collection or database, 3 minutes to examine the relevance of each document, and 4 hours of total search time. When written in steps, their search strategy spans over 15 lines and can reach up to 105 lines.\nWith the abundance of information sources in the medical domain, consumers are more and more faced with a similar challenge, one that needs dedicated solutions that can adapt to the heterogeneity and specifics of health-related information.\nDedicated Question Answering (QA) systems are one of the viable solutions to this problem as they are designed to understand natural language questions without relying on external information on the users.\nIn the context of QA, the goal of Recognizing Question Entailment (RQE) is to retrieve answers to a premise question ( INLINEFORM0 ) by retrieving inferred or entailed questions, called hypothesis questions ( INLINEFORM1 ) that already have associated answers. Therefore, we define the entailment relation between two questions as: a question INLINEFORM2 entails a question INLINEFORM3 if every answer to INLINEFORM4 is also a correct answer to INLINEFORM5 BIBREF1 .\nRQE is particularly relevant due to the increasing numbers of similar questions posted online BIBREF2 and its ability to solve differently the challenging issues of question understanding and answer extraction. In addition to being used to find relevant answers, these resources can also be used in training models able to recognize inference relations and similarity between questions.\nQuestion similarity has recently attracted international challenges BIBREF3 , BIBREF4 and several research efforts proposing a wide range of approaches, including Logistic Regression, Recurrent Neural Networks (RNNs), Long Short Term Memory cells (LSTMs), and Convolutional Neural Networks (CNNs) BIBREF5 , BIBREF6 , BIBREF1 , BIBREF7 .\nIn this paper, we study question entailment in the medical domain and the effectiveness of the end-to-end RQE-based QA approach by evaluating the relevance of the retrieved answers. Although entailment was attempted in QA before BIBREF8 , BIBREF9 , BIBREF10 , as far as we know, we are the first to introduce and evaluate a full medical question answering approach based on question entailment for free-text questions. Our contributions are:\nThe next section is dedicated to related work on question answering, question similarity and entailment. In Section SECREF3 , we present two machine learning (ML) and deep learning (DL) methods for RQE and compare their performance using open-domain and clinical datasets. Section SECREF4 describes the new collection of medical question-answer pairs. In Section SECREF5 , we describe our RQE-based approach for QA. Section SECREF6 presents our evaluation of the retrieved answers and the results obtained on TREC 2017 LiveQA medical questions.\nIn this paper, we study question entailment in the medical domain and the effectiveness of the end-to-end RQE-based QA approach by evaluating the relevance of the retrieved answers.",

In general, for people to migrate from India to the US one of the main criteria is exceptional academic performance with post graduate university qualifications in addition to being very proficient in English.So, the parents of these children of Indian origin have a strong academic educational background and try to create an environment at home that places great emphasis on academic learning.\n\nSpellBee has become very popular with the events being telecast on TV. The event is becoming more popular among the Indian community in the US as they see Indian kids being successful in the contests and getting national recognition when they perform well in SpellBee. When the Indian parents find that their kids are showing some aptitude in spelling and are capable of putting in the required effort, the parents start motivating the children to start practising for SpellBee contests. \n\nThese children of Indian origin spend significant effort over a period of several months or in some cases even years fine tuning their skills to practise for SpellBee contests.

        "evidence": "Author profiling is the characterization of an author through some key attributes such as gender, age, and language. It's an indispensable task especially in security, forensics, and marketing. Recently, social media has become a great data source for the potential learning approaches. Furthermore, gender prediction has been a popular profiling task.\nThe traditional approach to gender prediction problem is extracting a useful set of hand-crafted features and then feeding them into a standard classification algorithm. In their study, BIBREF0 work with the style-based features of message length, stop word usage, frequency of smiley etc. and use different classifiers such as k-nearest neighbor, naive bayes, covering rules, and backpropagation to predict gender on chat messages. Similarly, BIBREF1 select some hand-crafted features and feed them into various classifiers.\nMost of the work on gender prediction rely on n-gram features BIBREF2. BIBREF3 give Latent Semantic Analysis (LSA)-reduced forms of word and character n-grams into Support Vector Machine (SVM) and achieve state-of-the-art performance. Apart from exploiting n-gram frequencies, there are studies BIBREF4, BIBREF5, BIBREF6 to extract cross-lingual features to determine gender from tweets. Some other work BIBREF4, BIBREF7 exploit user metadata besides using just tweets.\nRecently, neural network-based models have been proposed to solve this problem. Rather than explicitly extracting features, the aim is to develop an architecture that implicitly learns. In author profiling, both style and content-based features were proved useful BIBREF8 and neural networks are able to capture both syntactic and semantic regularities. In general, syntactic information is drawn from the local context. On the other hand, semantic information is often captured with larger window sizes. Thus, CNNs are preferred to obtain style-based features while RNNs are the methods of choice for addressing content-based features BIBREF9. In literature, CNN BIBREF10 or RNN BIBREF11, BIBREF12, BIBREF13 is used on this task. BIBREF11 obtain state-of-the-art performance among neural methods by proposing a model architecture where they process text through RNN with GRU cells. Also, the presence of an attention layer is shown to boost the performance of neural methods BIBREF11, BIBREF10.\nIn this work, we propose a model that relies on RNN with attention mechanism (RNNwA). A bidirectional RNN with attention mechanism both on word level and tweet level is trained with word embeddings. The final representation of the user is fed to a fully connected layer for prediction. Since combining some hand-crafted features with a learned linear layer has shown to perform well in complex tasks like Semantic Role Labeling (SRL) BIBREF14, an improved version of the model (RNNwA + n-gram) is also tested with hand-crafted features. In the improved version, LSA-reduced n-gram features are concatenated with the neural representation of the user. Then the result is fed into a fully-connected layer to make prediction. Models are tested in three languages; English, Spanish, and Arabic, and the improved version achieves state-of-the-art accuracy on English, and competitive results on Spanish and Arabic corpus.\nThere are many datasets created for this task BIBREF15, BIBREF16. In this work, we have used the dataset and benchmarks provided by the PAN 2018 shared task on author profiling BIBREF15. As the dataset contains a constant number of 100 tweets per user, accuracy tests are performed both on user and tweet level (tweet-level predictions are made by removing the user-level attention). Tweet-level accuracy tests show interesting results during hyperparameter optimization. When the tweet-level predictions are averaged to produce user-level predictions, it is seen that the hyperparameters that gave the best results in terms of tweet-level accuracy, performs worse in user-level accuracy. The better user-level models, with different hyperparameters, that gave the highest user-level accuracy are observed to slightly overfit on tweet-level. It leads us to believe that the overfitting in the tweet-level predictions in best user-level models acts similar to an attention mechanism by over-emphasizing some distinctive tweets and ignoring the rest.\nIn this work, we propose a model that relies on RNN with attention mechanism (RNNwA). A bidirectional RNN with attention mechanism both on word level and tweet level is trained with word embeddings.",

In contrast to the waves in front of the coast, the asphalt one usually lands on when falling is pretty hard and rough - a circumstance felt by bones and skin. Skateboard riders usually fall quite a bit and despite all, the important thing is to get up and try again, and again, and again. It is just like in life where one grows with their challenges and needs to get up again until the goals are achieved. As humbling and painful as falling onto plain asphalt can be, it can also stimulate resilience and a relieving patience when the goal is in sight. Just try again.",

        "answer": "The final soft-max prediction layer will concatenate representations of two adjacent discourse units and predict the discourse relation between them.",
        "evidence": "Figure 1 illustrates the overall architecture of the discourse-level neural network model that consists of two Bi-LSTM layers, one max-pooling layer in between and one softmax prediction layer. The input of the neural network model is a paragraph containing a sequence of discourse units, while the output is a sequence of discourse relations with one relation between each pair of adjacent discourse units.\nGiven the words sequence of one paragraph as input, the lower Bi-LSTM layer will read the whole paragraph and calculate hidden states as word representations, and a max-pooling layer will be applied to abstract the representation of each discourse unit based on individual word representations. Then another Bi-LSTM layer will run over the sequence of discourse unit representations and compute new representations by further modeling semantic dependencies between discourse units within paragraph. The final softmax prediction layer will concatenate representations of two adjacent discourse units and predict the discourse relation between them.\nWord Vectors as Input: The input of the paragraph-level discourse relation prediction model is a sequence of word vectors, one vector per word in the paragraph. In this work, we used the pre-trained 300-dimension Google English word2vec embeddings. For each word that is not in the vocabulary of Google word2vec, we will randomly initialize a vector with each dimension sampled from the range $[-0.25, 0.25]$ . In addition, recognizing key entities and discourse connective phrases is important for discourse relation recognition, therefore, we concatenate the raw word embeddings with extra linguistic features, specifically one-hot Part-Of-Speech tag embeddings and one-hot named entity tag embeddings.\nBuilding Discourse Unit Representations: We aim to build discourse unit (DU) representations that sufficiently leverage cues for discourse relation prediction from paragraph-wide contexts, including the preceding and following discourse units in a paragraph. To process long paragraph-wide contexts, we take a bottom-up two-level abstraction approach and progressively generate a compositional representation of each word first (low level) and then generate a compositional representation of each discourse unit (high level), with a max-pooling operation in between. At both word-level and DU-level, we choose Bi-LSTM as our basic component for generating compositional representations, mainly considering its capability to capture long-distance dependencies between words (discourse units) and to incorporate influences of context words (discourse units) in each side.\nGiven a variable-length words sequence $X = (x_1,x_2,...,x_L)$ in a paragraph, the word-level Bi-LSTM will process the input sequence by using two separate LSTMs, one process the word sequence from the left to right while the other follows the reversed direction. Therefore, at each word position $t$ , we obtain two hidden states $\\overrightarrow{h_t}, \\overleftarrow{h_t}$ . We concatenate them to get the word representation $h_t = [\\overrightarrow{h_t}, \\overleftarrow{h_t}]$ . Then we apply max-pooling over the sequence of word representations for words in a discourse unit in order to get the discourse unit embedding: \n$$MP_{DU}[j] = \\max _{i=DU\\_start}^{DU\\_end}h_i[j]\\quad \\\\\nwhere, 1 \\le j \\le hidden\\_node\\_size$$   (Eq. 8) \nNext, the DU-level Bi-LSTM will process the sequence of discourse unit embeddings in a paragraph and generate two hidden states $\\overrightarrow{hDU_t}$ and $\\overleftarrow{hDU_t}$ at each discourse unit position. We concatenate them to get the discourse unit representation $hDU_t = [\\overrightarrow{hDU_t}, \\overleftarrow{hDU_t}]$ .\nThe Softmax Prediction Layer: Finally, we concatenate two adjacent discourse unit representations $hDU_{t-1}$ and $hDU_t$ and predict the discourse relation between them using a softmax function:\n$$y_{t-1} = softmax(W_y*[hDU_{t-1},hDU_t]+b_y)$$   (Eq. 9) \nThe final soft-max prediction layer will concatenate representations of two adjacent discourse units and predict the discourse relation between them.",

        "evidence": "Change is a universal property of language. For example, English has changed so much that Renaissance-era texts like The Canterbury Tales must now be read in translation. Even contemporary American English continues to change and diversify at a rapid pace—to such an extent that some geographical dialect differences pose serious challenges for comprehensibility BIBREF0 . Understanding language change is therefore crucial to understanding language itself, and has implications for the design of more robust natural language processing systems BIBREF1 .\nLanguage change is a fundamentally social phenomenon BIBREF2 . For a new linguistic form to succeed, at least two things must happen: first, speakers (and writers) must come into contact with the new form; second, they must decide to use it. The first condition implies that language change is related to the structure of social networks. If a significant number of speakers are isolated from a potential change, then they are unlikely to adopt it BIBREF3 . But mere exposure is not sufficient—we are all exposed to language varieties that are different from our own, yet we nonetheless do not adopt them in our own speech and writing. For example, in the United States, many African American speakers maintain a distinct dialect, despite being immersed in a linguistic environment that differs in many important respects BIBREF4 , BIBREF5 . Researchers have made a similar argument for socioeconomic language differences in Britain BIBREF6 . In at least some cases, these differences reflect questions of identity: because language is a key constituent in the social construction of group identity, individuals must make strategic choices when deciding whether to adopt new linguistic forms BIBREF7 , BIBREF8 , BIBREF9 . By analyzing patterns of language change, we can learn more about the latent structure of social organization: to whom people talk, and how they see themselves.\nBut, while the basic outline of the interaction between language change and social structure is understood, the fine details are still missing: What types of social network connections are most important for language change? To what extent do considerations of identity affect linguistic differences, particularly in an online context? Traditional sociolinguistic approaches lack the data and the methods for asking such detailed questions about language variation and change.\nIn this paper, we show that large-scale social media data can shed new light on how language changes propagate through social networks. We use a data set of Twitter users that contains all public messages for several million accounts, augmented with social network and geolocation metadata. This data set makes it possible to track, and potentially explain, every usage of a linguistic variable as it spreads through social media. Overall, we make the following contributions:\nWe excluded retweets, which are explicitly marked with metadata, and focused on messages that were posted in English from within the United States.",

        "question": "When did mountain biking start?",
        "evidence": "Late 1800s\nOne of the first examples of bicycles modified specifically for off-road use is the expedition of Buffalo Soldiers from Missoula, Montana, to Yellowstone in August 1896.[failed verification]\n\n1900s–1960s\nBicycles were ridden off-road by road racing cyclists who used cyclocross as a means of keeping fit during the winter. Cyclo-cross eventually became a sport in its own right in the 1940s, with the first world championship taking place in 1950.\n\nThe Rough Stuff Fellowship was established in 1955 by off-road cyclists in the United Kingdom.\n\nIn Oregon in 1966, one Chemeketan club member, D. Gwynn, built a rough terrain trail bicycle. He named it a \"mountain bicycle\" for its intended place of use. This may be the first use of that name.\n\nIn England in 1968, Geoff Apps, a motorbike trials rider, began experimenting with off-road bicycle designs. By 1979 he had developed a custom-built lightweight bicycle which was uniquely suited to the wet and muddy off-road conditions found in the south-east of England. They were designed around 2 inch x 650b Nokian snow tires though a 700x47c (28 in.) version was also produced. These were sold under the Cleland Cycles brand until late 1984. Bikes based on the Cleland design were also sold by English Cycles and Highpath Engineering until the early 1990s.\n\n1970s–1980s\nThere were several groups of riders in different areas of the U.S.A. who can make valid claims to playing a part in the birth of the sport. Riders in Crested Butte, Colorado, and Mill Valley, California, tinkered with bikes and adapted them to the rigors of off-road riding. Modified heavy cruiser bicycles, old 1930s and '40s Schwinn bicycles retrofitted with better brakes and fat tires, were used for freewheeling down mountain trails in Marin County, California, in the mid-to-late 1970s. At the time, there were no mountain bikes. The earliest ancestors of modern mountain bikes were based around frames from cruiser bicycles such as those made by Schwinn. The Schwinn Excelsior was the frame of choice due to its geometry. Riders used balloon-tired cruisers and modified them with gears and motocross or BMX-style handlebars, creating \"klunkers\". The term would also be used as a verb since the term \"mountain biking\" was not yet in use. The first person known to fit multiple speeds and drum brakes to a klunker is Russ Mahon of Cupertino, California, who used the resulting bike in cyclo-cross racing. Riders would race down mountain fire roads, causing the hub brake to burn the grease inside, requiring the riders to repack the bearings. These were called \"Repack Races\" and triggered the first innovations in mountain bike technology as well as the initial interest of the public (on Mt. Tamalpais in Marin CA, there is still a trail titled \"Repack\"—in reference to these early competitions). The sport originated in California on Marin County's Mount Tamalpais.\n\nIt was not until the late 1970s and early 1980s that road bicycle companies started to manufacture mountain bicycles using high-tech lightweight materials. Joe Breeze is normally credited with introducing the first purpose-built mountain bike in 1978. Tom Ritchey then went on to make frames for a company called MountainBikes, a partnership between Gary Fisher, Charlie Kelly and Tom Ritchey. Tom Ritchey, a welder with skills in frame building, also built the original bikes. The company's three partners eventually dissolved their partnership, and the company became Fisher Mountain Bikes, while Tom Ritchey started his own frame shop.\n\nThe first mountain bikes were basically road bicycle frames (with heavier tubing and different geometry) with a wider frame and fork to allow for a wider tire. The handlebars were also different in that they were a straight, transverse-mounted handlebar, rather than the dropped, curved handlebars that are typically installed on road racing bicycles. Also, some of the parts on early production mountain bicycles were taken from the BMX bicycle. Other contributors were Otis Guy and Keith Bontrager.\n\nTom Ritchey built the first regularly available mountain bike frame, which was accessorized by Gary Fisher and Charlie Kelly and sold by their company called MountainBikes (later changed to Fisher Mountain Bikes, then bought by Trek, still under the name Gary Fisher, currently sold as Trek's \"Gary Fisher Collection\"). The first two mass-produced mountain bikes were sold in the early 1980s: the Specialized Stumpjumper and Univega Alpina Pro. In 1988, The Great Mountain Biking Video was released, soon followed by others. In 2007, Klunkerz: A Film About Mountain Bikes was released, documenting mountain bike history during the formative period in Northern California. Additionally, a group of mountain bikers called the Laguna Rads formed a club during the mid eighties and began a weekly ride, exploring the uncharted coastal hillsides of Laguna Beach, California. Industry insiders suggest that this was the birth of the freeride movement, as they were cycling up and down hills and mountains where no cycling specific trail network prexisted. The Laguna Rads have also held the longest running downhill race once a year since 1986.\n\nAt the time, the bicycle industry was not impressed with the mountain bike, regarding mountain biking to be short-term fad. In particular, large manufacturers such as Schwinn and Fuji failed to see the significance of an all-terrain bicycle and the coming boom in 'adventure sports'. Instead, the first mass-produced mountain bikes were pioneered by new companies such as MountainBikes (later, Fisher Mountain Bikes), Ritchey, and Specialized. Specialized was an American startup company that arranged for production of mountain bike frames from factories in Japan and Taiwan. First marketed in 1981, Specialized's mountain bike largely followed Tom Ritchey's frame geometry, but used TiG welding to join the frame tubes instead of fillet-brazing, a process better suited to mass production, and which helped to reduce labor and manufacturing cost. The bikes were configured with 15 gears using derailleurs, a triple chainring, and a cogset with five sprockets.",
        "answer": "Mountain biking as a sport came into existence in various areas in the USA in the late 1970s and early 1980s.  While many groups of riders in different US locations claim the birthright to mountain biking, it's clear that there wasn't a single person nor a single location that served as the starting point for the sport.  Riders in Crested Butte, CO, Marin County, CA, Mill Valley, CA, Cupertino, CA, and several other locations contributed significantly to the birth of the sport.\n\nIt wasn't until the late 1970s and early 1980s that bicycle companies began manufacturing mountain bikes with specific high-tech lightweight materials that popularized the sport.  Joe Breeze (Marin County) is often credited with building the first, purpose-built mountain bike in 1978.\n\nIt's important to note that there were mountain bike concepts and prototypes built well before this period, with the earliest concept belonging to the off-road bicycles used by the Buffalo Soldiers in 1896.",

        "question": "Should superheroes be allowed to break the law?",
        "evidence": "",
        "answer": "In Ralph Waldo Emerson’s essay “The Conservative,” he claims that the law doesn’t affect heroes because they will do what is right no matter what. While the term hero is subjective, as not all people who break the laws are heroes, Emerson is correct to argue that to be truly just and great sometimes requires breaking the law.\n\tA common example of greatness is superheroes; their extraordinary physical abilities put to use to save the world from evil. However, their greatness sometimes conflicts with the law. For example, in Spiderman, Peter Parker choses to keep his identity a secret, to protect himself not only from paparatzi like J. Jonah Jameson (JK Simmons), but also from police. Though Spiderman is a hero at heart, he commits murder, puts people in harms way, and destroys buildings and public spaces. However, because he is a hero, he is able to “outshine” the law in order to continue to help and save the people of New York.\n\tAnother example of sacraficial heroism is playing defensive soccer, only is this case the laws are the rules and breaking them is just a foul. A good defender knows that when their defense is outnumbered by the opposing attackers, their defense is out of position, or their goalie is out of position, you have to commit a foul. Though the foul gives the other team an opportunity to set up a potential scoring play, the sacrifice must be made in order for the defense to recollect and reorganize, allowing them to be better prepared for the attack. Though this form of heroism isn’t as grand as Spiderman, breaking the “laws” of the game is still very important and generally considered to be the smarter play.\n\tThough Emerson’s point is generally true, there are some faults, the most important one being that not everyone who breaks the law is considered to be a hero to everyone. Though this struggle can also be seen is Spiderman, a much better example is our former president, Donald Trump. Former President Trump has escaped paying taxes, began violent riots, and has even been impeached for using his position to attempt to take down a political rival (President Biden). In many Americans eyes, Donald Trump is not a hero but a villan who gained power by uniting his followers with rage, creating a cult of angry conservatives who follow his every order. However, to those who do support him, Trump is a hero who saved the USA from “crazy liberals” like Bernie Sanders and Hilary Clinton. There are hundreds of thousands of people who break the law who aren’t heroes, like Donald Trump.\n\tOn the contrary, in some cases, sometimes being a hero requires breaking the law in order to achieve equality. On of the greatest examples of law-breaking heroes is Gandhi, the Indian nationalist whose goal was achieving India’s independence from the British. Gandhi, though he is considered to be one of the most respected role models for peace, was imprisoned 11 times for breaking British laws in India. He used his imprisonments to unite Indians to rise against the British government with non-violent protesting. Gandhi encouraged people to break the law in order to expose the horrible violence that the British inflicted on India. Gandhi was and is a hero to many and yet he broke the law hundreds of times.\n\tBeing a true hero takes guts, compassion, and sacrifice, all of which support Emerson’s idea that true heroes don’t need to follow the law. Laws are created as a social contract, an idea which came from enlightenment philosophe Jean-Jaques Rousseau, who believed that the social contract bound our society together and kept people in check based on the morals and values of the community. The purpose of laws is to create equality for large amounts of people, an equality that stops people from doing whatever they want that could potentially disrupt society. \nHowever, humans are imperfect and because of that humans can create imperfect laws. One rule that Gandhi fought against was that Indians couldn’t make their own salt from the ocean, they had to purchase it from the British, who had plainly taken the salt from India, sent it back to England to be processed, and then shipped it back to India to make a profit. Gandhi argued why must Indians buy british salt when we can make our own Indian salt right here? This law was clearly ridiculous: why should Indians have to buy British salt? \nIt is because of imperfect laws that heroes, like Gandhi, should break the law and make their own salt. Sometimes breaking the law allows Spiderman to save the city from the Green Goblin, or allows the defense to organize and defeat their oposing attackers, or allows Gandhi to free India from the violent control of the British Empire. Yes not all who break the law are good, but heroes who break the law outshine the law in order to create more good and improve the world we live in.",

BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch?

Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nTo our best knowledge, there are only three publicly available multilingual pretrained models to date:",

        "answer": "It is is easy-to-implement, effective, and can replace conventional stacked LSTMs without much modification of the overall architecture.",
        "evidence": "In the field of natural language processing (NLP), the most prevalent neural approach to obtaining sentence representations is to use recurrent neural networks (RNNs), where words in a sentence are processed in a sequential and recurrent manner. Along with their intuitive design, RNNs have shown outstanding performance across various NLP tasks e.g. language modeling BIBREF0 , BIBREF1 , machine translation BIBREF2 , BIBREF3 , BIBREF4 , text classification BIBREF5 , BIBREF6 , and parsing BIBREF7 , BIBREF8 .\nAmong several variants of the original RNN BIBREF9 , gated recurrent architectures such as long short-term memory (LSTM) BIBREF10 and gated recurrent unit (GRU) BIBREF2 have been accepted as de-facto standard choices for RNNs due to their capability of addressing the vanishing and exploding gradient problem and considering long-term dependencies. Gated RNNs achieve these properties by introducing additional gating units that learn to control the amount of information to be transferred or forgotten BIBREF11 , and are proven to work well without relying on complex optimization algorithms or careful initialization BIBREF12 .\nMeanwhile, the common practice for further enhancing the expressiveness of RNNs is to stack multiple RNN layers, each of which has distinct parameter sets (stacked RNN) BIBREF13 , BIBREF14 . In stacked RNNs, the hidden states of a layer are fed as input to the subsequent layer, and they are shown to work well due to increased depth BIBREF15 or their ability to capture hierarchical time series BIBREF16 which are inherent to the nature of the problem being modeled.\nHowever this setting of stacking RNNs might hinder the possibility of more sophisticated recurrence-based structures since the information from lower layers is simply treated as input to the next layer, rather than as another class of state that participates in core RNN computations. Especially for gated RNNs such as LSTMs and GRUs, this means that layer-to-layer connections cannot fully benefit from the carefully constructed gating mechanism used in temporal transitions. Some recent work on stacking RNNs suggests alternative methods that encourage direct and effective interaction between RNN layers by adding residual connections BIBREF17 , BIBREF18 , by shortcut connections BIBREF18 , BIBREF19 , or by using cell states of LSTMs BIBREF20 , BIBREF21 .\nIn this paper, we propose a method of constructing multi-layer LSTMs where cell states are used in controlling the vertical information flow. This system utilizes states from the left and the lower context equally in computation of the new state, thus the information from lower layers is elaborately filtered and reflected through a soft gating mechanism. Our method is easy-to-implement, effective, and can replace conventional stacked LSTMs without much modification of the overall architecture.\nWe call the proposed architecture Cell-aware Stacked LSTM, or CAS-LSTM, and evaluate our method on multiple benchmark datasets: SNLI BIBREF22 , MultiNLI BIBREF23 , Quora Question Pairs BIBREF24 , and SST BIBREF25 . From experiments we show that the CAS-LSTMs consistently outperform typical stacked LSTMs, opening the possibility of performance improvement of architectures that use stacked LSTMs.\nOur contribution is summarized as follows.\nThis paper is organized as follows. We give a detailed description about the proposed method in § SECREF2 . Experimental results are given in § SECREF3 . We study prior work related to our objective in § SECREF4 and conclude in § SECREF5 .\nOur method is easy-to-implement, effective, and can replace conventional stacked LSTMs without much modification of the overall architecture.",

Instead, we focus on the anytime performance at the stream level where ticks are given by mega-batches.

        "evidence": "There have been many recent successes in the field of Reinforcement Learning. In the online RL setting, an agent takes actions, observes the outcome from the environment, and updates its policy based on the outcome. This repeated access to the environment is not feasible in practical applications; it may be unsafe to interact with the actual environment, and a high-fidelity simulator may be costly to build. Instead, offline RL, consumes fixed training data which consist of recorded interactions between one (or more) agent(s) and the environment to train a policy). An agent with the trained policy is then deployed in the environment without further evaluation or modification. Notice that in offline RL, the deployed agent must consume data in the same format (for example,having the same features) as in the training data. This is a crippling restriction in many large-scale applications, where, due to some combination of resource/system constraints, all of the features used for training cannot be observed (or misspecified) by the agent during online operation. In this work, we lay the foundations for studying this Resource-Constrained setting for offline RL. We then provide an algorithm that improves performance by transferring information from the full-featured offline training set to the deployed agent's policy acting on limited features. We first illustrate a few practical cases where resource-constrained settings emerge.\nSystem Latency A deployed agent is often constrained by how much time it has to process the state of the environment and make a decision. For example, in a customer-facing web application, the customer will start to lose interest within a fraction of a second.

The limited compute power of the robot prevents it from using powerful feature extractors while making a decision. However, such powerful feature extractors can be used during the offline training of the robot (Fig).\nIn the resource-constrained setting, one can simply ignore the offline features and only train the offline agent with the online features that are available during deployment. This strategy has the drawback of not utilizing all of the information available during training and can lead to a sub-optimal policy. To confirm this, we performed the following simple experiment. We consider an offline RL dataset for the OpenAI gym MuJoCo HalfCheetah-v2 environment and simulate the resourceconstrained setting by removing a fixed set of randomly selected features during deployment (see Sections 5.1.1, C.1 for more details). We train an offline RL algorithm, TD3+BC using only the online features and collect online data in the environment using the trained policy. We repeat this assuming all features available during deployment, train a TD3+BC agent using the same offline dataset with all features, and collect online data in the environment. We plot the histogram of rewards in the two datasets in Fig 1b We observe that the agent trained only with online features obtains much smaller reward than the agent trained with offline features.\nTraditionally, scenarios where the observability of the state of the system is limited are studied under the Partially Observable Markov Decision Process (POMDP) setting by assuming a belief over the observations.

        "evidence": "We compare the statistical characteristics of the vocabulary of JT-VAE that contains 780 substructures and the vocabulary of graph pieces with a size of 100, 300, 500, and 700. Figure shows the proportion of substructures with different numbers of atoms in the vocabulary and their frequencies of occurrence in the ZINC250K dataset. The substructures in the vocabulary of JT-VAE mainly concentrate on 5 to 8 atoms with a sharp distribution. However, starting from substructures with 3 atoms, the frequency of occurrence is already close to zero. Therefore, the majority of substructures in the vocabulary of JT-VAE are actually not common substructures. On the contrary, the substructures in the vocabulary of graph pieces have a relatively smooth distribution over 4 to 10 atoms. Moreover, these substructures also have a much higher frequency of occurrence compared to those in the vocabulary of JT-VAE. We present samples of graph pieces in Appendix H.\nFigure: The left and right figures show the proportion of and frequency of occurrence of substructures with different number of atoms in the vocabulary, respectively.\nTo analyze the graph piece-property correlation and whether our model can discover and utilize the correlation, we present the normalized distribution of generated graph pieces and Pearson correlation coefficient between the graph pieces and the score of Penalized logP (PlogP) in Figure.\nThe curve of the Pearson correlation coeffcient indicates that some graph pieces positively correlate with PlogP and some negatively correlate with it. Compared with the flat distribution under the nonoptimization setting, the generated distribution shifts towards the graph pieces positively correlated with PlogP under the PlogP-optimization setting. The generation of graph pieces negatively correlated with PlogP is also suppressed. Therefore, correlations exist between graph pieces and PlogP, and our model can accurately discover and utilize these correlations for PlogP optimization.\nThe algorithm for extracting graph pieces from a given set of graphs D is given in Algorithm 1. Our algorithm draws inspiration from Byte Pair Encoding (Gage, 1994, BPE). Initially, a graph G in D is decomposed into atom-level graph pieces and the vocabulary S of graph pieces is composed of all unique atom-level graph pieces that appear in D. Given the number N of graph pieces to learn, at each iteration, our algorithm enumerates all neighboring graph pieces and edges that connect the two graph pieces in G, namely hPi ,Pj , E˜ ij i. As hPi ,Pj , E˜ ij i is also a valid subgraph, we merge it into a graph piece and count its occurrence. We find the most frequent merged graph piece P and add it into the vocabulary S. After that, we also update graphs G in D that contain P by merging hPi ,Pj , E˜ ij i into P. The algorithm terminates when the vocabulary size exceeds the predefined number N. Note that we use SMILES (Weininger, 1988) to represent a graph piece in our algorithm1 , therefore we ensure the uniqueness of a graph piece. A running example of our graph piece extraction algorithm is illustrated in Figure 3. At test time, we first decompose a molecular graph into atom-level graph pieces, then apply the learned operations to merge the graph pieces into larger ones. This process ensures there is a piece-level decomposition for an arbitrary molecule.****Then the algorithm iteratively merge the graph piece pair which has the highest recorded frequency of occurrence in the\nvocabulary until all graph piece pairs are not in the vocabulary.",

        "evidence": "",
        "answer": "Data visualisation in any context is the art and science of organising data in such a way that makes it easily consumable by a human audience. Specifically, in the context of business intelligence, you are typically presenting facts and insights about a business to stakeholders in order for them to take action and make better decisions to run that business. \n\nGood data visualisation combines user experience design with an understanding of how people interpret data to provide something intuitive and compelling for the intended audience to use. \n\nHere are some examples of design and interpretation choices you might make:\n\nIn terms of design, many cultures write on a page from top to bottom, left to right. This means that the first place on any visualisation that a person from any of these cultures will look is top left. Consequently, the content you put in the top left space of your dashboard should be a critically important part of the story you are trying to tell. In a culture that writes right to left you might put higher-value content on the right-hand side of the visualisation. \n\nIn terms of in terms interpretation you want to key into things that people are naturally good at interpreting. For example, if you are presenting sales by product category and you have 10 product categories you could choose to leverage a bar chart where the length of the bar represents sales or a pie chart where the angle of the slice represents sales. A bar chart would be a better choice because people find it easy to compare the length of a bar. We cannot distinguish between the sizes of a slice with anywhere near the same level of accuracy. Choosing a pie chart would leave your users spending more time and effort interpreting your data visualisation than if you had chosen a bar chart to present the information to them.",

        "question": "Is the classifier designed especially for South African languages？",
        "answer": "Yes.",
        "evidence": "Accurate language identification (LID) is the first step in many natural language processing and machine comprehension pipelines. If the language of a piece of text is known then the appropriate downstream models like parts of speech taggers and language models can be applied as required.\nLID is further also an important step in harvesting scarce language resources. Harvested data can be used to bootstrap more accurate LID models and in doing so continually improve the quality of the harvested data. Availability of data is still one of the big roadblocks for applying data driven approaches like supervised machine learning in developing countries.\nHaving 11 official languages of South Africa has lead to initiatives (discussed in the next section) that have had positive effect on the availability of language resources for research. However, many of the South African languages are still under resourced from the point of view of building data driven models for machine comprehension and process automation.\nTable TABREF2 shows the percentages of first language speakers for each of the official languages of South Africa. These are four conjunctively written Nguni languages (zul, xho, nbl, ssw), Afrikaans (afr) and English (eng), three disjunctively written Sotho languages (nso, sot, tsn), as well as tshiVenda (ven) and Xitsonga (tso). The Nguni languages are similar to each other and harder to distinguish. The same is true of the Sotho languages.\nThis paper presents a hierarchical naive Bayesian and lexicon based classifier for LID of short pieces of text of 15-20 characters long. The algorithm is evaluated against recent approaches using existing test sets from previous works on South African languages as well as the Discriminating between Similar Languages (DSL) 2015 and 2017 shared tasks.\nSection SECREF2 reviews existing works on the topic and summarises the remaining research problems. Section SECREF3 of the paper discusses the proposed algorithm and Section SECREF4 presents comparative results.\nThe proposed LID algorithm builds on the work in BIBREF8 and BIBREF26. We apply a naive Bayesian classifier with character (2, 4 & 6)-grams, word unigram and word bigram features with a hierarchical lexicon based classifier.\nThe naive Bayesian classifier is trained to predict the specific language label of a piece of text, but used to first classify text as belonging to either the Nguni family, the Sotho family, English, Afrikaans, Xitsonga or Tshivenda. The scikit-learn multinomial naive Bayes classifier is used for the implementation with an alpha smoothing value of 0.01 and hashed text features.\nThe lexicon based classifier is then used to predict the specific language within a language group. For the South African languages this is done for the Nguni and Sotho groups. If the lexicon prediction of the specific language has high confidence then its result is used as the final label else the naive Bayesian classifier's specific language prediction is used as the final result. The lexicon is built over all the data and therefore includes the vocabulary from both the training and testing sets.\nThe lexicon based classifier is designed to trade higher precision for lower recall. The proposed implementation is considered confident if the number of words from the winning language is at least one more than the number of words considered to be from the language scored in second place.\nThe stacked classifier is tested against three public LID implementations BIBREF17, BIBREF23, BIBREF8. The LID implementation described in BIBREF17 is available on GitHub and is trained and tested according to a post on the fasttext blog. Character (5-6)-gram features with 16 dimensional vectors worked the best. The implementation discussed in BIBREF23 is available from https://github.com/tomkocmi/LanideNN. Following the instructions for an OSX pip install of an old r0.8 release of TensorFlow, the LanideNN code could be executed in Python 3.7.4. Settings were left at their defaults and a learning rate of 0.001 was used followed by a refinement with learning rate of 0.0001. Only one code modification was applied to return the results from a method that previously just printed to screen. The LID algorithm described in BIBREF8 is also available on GitHub.\nThe stacked classifier is also tested against the results reported for four other algorithms BIBREF16, BIBREF26, BIBREF24, BIBREF15. All the comparisons are done using the NCHLT BIBREF7, DSL 2015 BIBREF19 and DSL 2017 BIBREF1 datasets discussed in Section SECREF2.\nThis paper presents a hierarchical naive Bayesian and lexicon based classifier for LID of short pieces of text of 15-20 characters long.

        "evidence": "Cancer is one of the leading causes of death in the world, with over 80,000 deaths registered in Canada in 2017 (Canadian Cancer Statistics 2017). A computer-aided system for cancer diagnosis usually involves a pathologist rendering a descriptive report after examining the tissue glass slides obtained from the biopsy of a patient. A pathology report contains specific analysis of cells and tissues, and other histopathological indicators that are crucial for diagnosing malignancies. An average sized laboratory may produces a large quantity of pathology reports annually (e.g., in excess of 50,000), but these reports are written in mostly unstructured text and with no direct link to the tissue sample. Furthermore, the report for each patient is a personalized document and offers very high variability in terminology due to lack of standards and may even include misspellings and missing punctuation, clinical diagnoses interspersed with complex explanations, different terminology to label the same malignancy, and information about multiple carcinoma appearances included in a single report BIBREF0 .\nIn Canada, each Provincial and Territorial Cancer Registry (PTCR) is responsible for collecting the data about cancer diseases and reporting them to Statistics Canada (StatCan). Every year, Canadian Cancer Registry (CCR) uses the information sources of StatCan to compile an annual report on cancer and tumor diseases. Many countries have their own cancer registry programs. These programs rely on the acquisition of diagnostic, treatment, and outcome information through manual processing and interpretation from various unstructured sources (e.g., pathology reports, autopsy/laboratory reports, medical billing summaries). The manual classification of cancer pathology reports is a challenging, time-consuming task and requires extensive training BIBREF0 .\nWith the continued growth in the number of cancer patients, and the increase in treatment complexity, cancer registries face a significant challenge in manually reviewing the large quantity of reports BIBREF1 , BIBREF0 . In this situation, Natural Language Processing (NLP) systems can offer a unique opportunity to automatically encode the unstructured reports into structured data. Since, the registries already have access to the large quantity of historically labeled and encoded reports, a supervised machine learning approach of feature extraction and classification is a compelling direction for making their workflow more effective and streamlined. If successful, such a solution would enable processing reports in much lesser time allowing trained personnel to focus on their research and analysis. However, developing an automated solution with high accuracy and consistency across wide variety of reports is a challenging problem.\nFor cancer registries, an important piece of information in a pathology report is the associated ICD-O code which describes the patient's histological diagnosis, as described by the World Health Organization's (WHO) International Classification of Diseases for Oncology BIBREF2 . Prediction of the primary diagnosis from a pathology report provides a valuable starting point for exploration of machine learning techniques for automated cancer surveillance. A major application for this purpose would be “auto-reporting” based on analysis of whole slide images, the digitization of the biopsy glass slides. Structured, summarized and categorized reports can be associated with the image content when searching in large archives. Such as system would be able to drastically increase the efficiency of diagnostic processes for the majority of cases where in spite of obvious primary diagnosis, still time and effort is required from the pathologists to write a descriptive report.\nThe primary objective of our study is to analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories. We demonstrate that TF-IDF feature vectors combined with linear SVM or XGBoost classifier can be an effective method for classification of the reports, achieving up to 83% accuracy. We also show that TF-IDF features are capable of identifying important keywords within a pathology report. Furthermore, we have created a new dataset consisting of 1,949 pathology reports across 37 primary diagnoses. Taken together, our exploratory experiments with a newly introduced dataset on pathology reports opens many new opportunities for researchers to develop a scalable and automatic information extraction from unstructured pathology reports.\nFurthermore, we have created a new dataset consisting of 1,949 pathology reports across 37 primary diagnoses.",

        "evidence": "Real-world data, including images, videos, genetic expressions, natural languages, or financial statistics, usually have a high dimensionality. The intrinsic dimensionality of these data, however, is typically much lower than its ambient dimension, which property is recognized as an important underlying reason for modern machine learning to work. To capture useful information from high-dimensional data, dimensionality reduction (DR) is of both theoretical and practical value.\nDR is essential for data visualization. A space with a dimensionality higher than 3, however, is already beyond our accustomed way of observing data, and our intuition in 2-dimensional or 3-dimensional space may not apply. High-dimensional space is not a trivial extension of lowdimensional space; theoretical research on high-dimensional geometry and statistics revealed a number of intriguing, non-intuitive phenomena in high-dimensional space. Imagine a hyper-sphere with a radius r in a d-dimensional Euclidean space whose central point is at the origin. Consider a \"crust\" of the d-dimensional hyper-sphere, which is between the surfaces of this hypersphere and a slightly smaller concentric hyper-sphere with radius (1−ϵ)r, where ϵ is small (Figure a). The ratio of the volume of the \"crust\" C d (r) to the hyper-sphere is V d (r) is C d (r)\nV d (r) = 1 − (1 − ϵ) d . Take ϵ = 0.01, it is easy to show that when d is small, the ratio is tiny (as our intuition goes), however this ratio grows exponentially fast to near 100% with the increase of dimensionality, as illustrated in figure 1 a-b. The volume of a high-dimensional hyper-sphere is therefore counter-intuitively concentrated on a crust (1 c). Such concentration explains the \"crowding problem\" of DR (van der: a faithful preservation of distances in high-dimensional space would lead to crowded data points. t-distributed Stochastic Neighbor Embedding (t-SNE) and Uniform Manifold Approximation and Projection (UMAP) are among the most established DR methods today, both of which mitigate this crowding problem by modeling the low-dimensional similarity measure with a longer-tail distribution than high-dimensional similarity measure (e.g. t distribution vs. Gaussian in the case of t-SNE). Such a disparity in similarity measure amounts to a distortion of distance between two spaces, but in a highly implicit manner. Both methods perform well empirically, but the underlying distortion of distance measure in two spaces cannot be analytically expressed or validated. Furthermore, the implicity of distance transformation deters us from imposing priors in data if there is any (e.g. a Swiss Roll has an intrinsic dimensionality of 2).\nAnother important property of real-world high-dimensional data is that they often exhibit a hierarchical structure (sub-manifolds on large manifolds), governed by the underlying generative models. Such hierarchy demands different treatment of data points by DR at different relative position. The state-of-the-art DR methods, such as UMAP and Barnes-Hut t-SNE (van der Maaten, 2014), commonly consider on a selected neighborhood (as a hyper-parameter) while discarding the far field beyond it. Isomap, on the other hand, taking both near and far field into account by calculating distances on a connected graph. t-SNE and UMAP works well on data of disjoint manifolds such as MNIST, while Isomap works well on data of continuous manifold such as Swiss roll. However, it is generally difficult for one method to succeed in both disjoint and continuous data manifolds.\nIn this paper, we seek to develop a novel DR method that is based on the following two key ideas, and strive to address the two aforementioned issues:\n• Space Expansion: Matching the \"capacity\" in high-dimensional and low-dimensional space, by explicit, quantitative transformation of distance measure;\n• Hierarchical Manifold Approximation: Data-specific, hierarchical modeling of similarities in high-dimensional data, to accommodate both disjoint and continuous data manifolds.\nIn the setting of generally anisotropic features, this paper gives an asymptotic characterization of the generalization risk curve with more samples. The asymptotic regime is an approximation for large n, d and can also shed light on practical machine learning problems. We first introduce our problem setup.",

        "evidence": "The recently introduced BERT model BIBREF0 exhibits strong performance on several language understanding benchmarks. To what extent does it capture syntax-sensitive structures?\nRecent work examines the extent to which RNN-based models capture syntax-sensitive phenomena that are traditionally taken as evidence for the existence in hierarchical structure. In particular, in BIBREF1 we assess the ability of LSTMs to learn subject-verb agreement patterns in English, and evaluate on naturally occurring wikipedia sentences. BIBREF2 also consider subject-verb agreement, but in a “colorless green ideas” setting in which content words in naturally occurring sentences are replaced with random words with the same part-of-speech and inflection, thus ensuring a focus on syntax rather than on selectional-preferences based cues. BIBREF3 consider a wider range of syntactic phenomena (subject-verb agreement, reflexive anaphora, negative polarity items) using manually constructed stimuli, allowing for greater coverage and control than in the naturally occurring setting.\nThe BERT model is based on the “Transformer” architecture BIBREF4 , which—in contrast to RNNs—relies purely on attention mechanisms, and does not have an explicit notion of word order beyond marking each word with its absolute-position embedding. This reliance on attention may lead one to expect decreased performance on syntax-sensitive tasks compared to RNN (LSTM) models that do model word order directly, and explicitly track states across the sentence. Indeed, BIBREF5 finds that transformer-based models perform worse than LSTM models on the BIBREF1 agreement prediction dataset. In contrast, BIBREF6 find that self-attention performs on par with LSTM for syntax sensitive dependencies in the context of machine-translation, and performance on syntactic tasks is correlated with the number of attention heads in multi-head attention.\nI adapt the evaluation protocol and stimuli of BIBREF1 , BIBREF2 and BIBREF3 to the bidirectional setting required by BERT, and evaluate the pre-trained BERT models (both the Large and the Base models). Surprisingly (at least to me), the out-of-the-box models (without any task-specific fine-tuning) perform very well on all the syntactic tasks.\nI adapt the evaluation protocol and stimuli of Linzen et al. (2016), Gulordava et al. (2018) and Marvin and Linzen (2018) to the bidirectional setting required by BERT, and evaluate the pre-trained BERT models (both the Large and the Base models).",

        "evidence": "Recent years have seen a large increase in the amount of disinformation and fake news spread on social media. False information was used to spread fear and anger among people, which in turn, provoked crimes in some countries. The US in the recent years experienced many similar cases during the presidential elections, such as the one commonly known as “Pizzagate\" . Later on, Twitter declared that they had detected a suspicious campaign originated in Russia by an organization named Internet Research Agency (IRA), and targeted the US to affect the results of the 2016 presidential elections. The desired goals behind these accounts are to spread fake and hateful news to further polarize the public opinion. Such attempts are not limited to Twitter, since Facebook announced in mid-2019 that they detected a similar attempt originating from UAE, Egypt and Saudi Arabia and targeting other countries such as Qatar, Palestine, Lebanon and Jordan. This attempt used Facebook pages, groups, and user accounts with fake identities to spread fake news supporting their ideological agendas. The automatic detection of such attempts is very challenging, since the true identity of these suspicious accounts is hidden by imitating the profiles of real persons from the targeted audience; in addition, sometimes they publish their suspicious idea in a vague way through their tweets' messages.\nA previous work BIBREF0 showed that such suspicious accounts are not bots in a strict sense and they argue that they could be considered as “software-assisted human workers\". According to BIBREF1, the online suspicious accounts can be categorized into 3 main types: Robots, Cyborgs, and Human Spammers. We consider IRA accounts as another new emerging type called trolls, which is similar to Cyborgs except that the former focuses on targeting communities instead of individuals.\nIn this work, we identify online trolls in Twitter, namely IRA trolls, from a textual perspective. We study the effect of a set of text-based features and we propose a machine learning model to detect them. We aim to answer three research questions: RQ1. Does the thematic information improve the detection performance?, RQ2. Can we detect IRA trolls from only a textual perspective? and RQ3. How IRA campaign utilized the emotions to affect the public opinions?\nThe rest of the paper is structured as follows. In the following section, we present an overview on the literature work on IRA trolls. In Section SECREF3, we describe how the used dataset was compiled. Section SECREF4 describes our proposed features for our approach. The experiments, results, and analyses are presented in Section SECREF5. Finally, we draw some conclusions and discuss possible future work on IRA trolls.\nIn this work, we identify online trolls in Twitter, namely IRA trolls, from a textual perspective.",

As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page.

In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them).

Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower.

The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years.

        "question": "What did the novel approach for automatically predicting based on?",
        "answer": "It bases on a rich input representation.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nWe develop a novel approach for automatically predicting which claims should be prioritized for factchecking, based on a rich input representation.",

        "evidence": "The Panama Canal is an artificial 82 km (51 mi) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan.\n\nColombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the project on May 4, 1904, and opened the canal on August 15, 1914. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for its handover to Panama. After a period of joint American–Panamanian control, the canal was taken over by the Panamanian government in 1999. It is now managed and operated by the government-owned Panama Canal Authority.\n\nCanal locks at each end lift ships up to Gatun Lake, an artificial lake 26 meters (85 ft) above sea level, created to reduce the amount of excavation work required for the canal, and then lower the ships at the other end. The original locks are 33.5 meters (110 ft) wide. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded waterway began commercial operation on June 26, 2016. The new locks allow transit of larger, New Panamax ships.\n\nAnnual traffic has risen from about 1,000 ships in 1914, when the canal opened, to 14,702 vessels in 2008, for a total of 333.7 million Panama Canal/Universal Measurement System (PC/UMS) tons. By 2012, more than 815,000 vessels had passed through the canal. In 2017 it took ships an average of 11.38 hours to pass between the canal's two locks.

        "question": "What does the meta network is used to?",
        "answer": "It is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function.",
        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nThe meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function.",

        "evidence": "As discussed in Section \"Introduction\" , we find three observations that show the usefulness of linked entities for abstractive summarization.\nFirst, summaries are mainly composed of linked entities extracted from the original text. In the example, it can be seen that the summary contains four words that refer to different entities. In fact, all noun phrases in the summary mention at least one linked entity. In our experimental data, we extract linked entities from the original text and compare them to the noun phrases found in the summary. We report that $77.1\\%$ and $75.1\\%$ of the noun phrases on the Gigaword and CNN datasets, respectively, contain at least one linked entity, which confirms our observation.\nSecond, linked entities can be used to represent the topic of the summary, defined as a multinomial distribution over entities, as graphically shown in the example, where the probabilities refer to the relevance of the entities. Entities have been previously used to represent topics BIBREF7 , as they can be utilized as a controlled vocabulary of the main topics in a document BIBREF8 . In the example, we see that the entity “Jae Seo” is the most relevant because it is the subject of the summary, while the entity “South Korean” is less relevant because it is less important when constructing the summary.\nThird, we can make use of the entity commonsense that can be learned as a continuous vector representation from a separate larger corpus BIBREF9 , BIBREF10 . In the example, if we know that the entities “Los Angeles Dodgers” and “New York Mets” are American baseball teams and “Jae Seo” is a baseball player associated with the teams, then we can use this information to generate more coherent summaries. We find that $76.0\\%$ of the extracted linked entities are covered by the pre-trained vectors in our experimental data, proving our third observation.\nAs discussed in Section 1, we find three observations that show the usefulness of linked entities for abstractive summarization.",

        "evidence": "",
        "answer": "Jazz music encompasses a wide range of styles, genres and periods, so it can be difficult and confusing for the non-jazz listener to find a satisfying entry point. There have been many “greatest of all time” jazz album lists developed by jazz publications and critics over the years. The following is a brief sampling of some of the top-rated albums from some of these lists.\n- Miles Davis: Kind of Blue (1959) Miles Davis’ masterpiece. One of the most influential albums of all time, because of its widespread influence on jazz, rock and classical genres. It is the greatest selling jazz album of all time, and usually the number one pick on critics’ albums rankings. It features a cool, atmospheric modal approach that is immediately recognizable, tuneful and approachable for just about any listener.\n- John Coltrane: A Love Supreme (1964). Widely regarded as John Coltrane’s masterpiece, it is an intense modal jazz through-composed spiritual meditation in four parts. Every critic interprets John Coltrane’s intent and meaning of A Love Supreme differently. Whether you think he’s searching for some form of soulful purity, or cutting out the middle man to speak directly to God, your jazz-listening life won’t be the same after hearing this searing testament.\n- Sonny Rollins: Saxophone Collosus (1957). Sonny Rollins’ breakthrough and best-known album. Rollins emerges here as a true jazz giant belonging in the same pantheon as Coltrane, Ben Webster, Coleman Hawkins and Lester Young. His strong and highly rhythmic thematic improvisational voice is on brilliant display in ‘St. Thomas’ and ‘Blue 7’. Not to be missed is his powerful rendition of the jazz standard ‘You Don’t Know Love’ and his lovely solo during Kurt Weil’s ‘Moritat’ (also known as ‘Mack the Knife’).\n- Dave Brubeck: Time Out (1959) Featuring uncommon time signatures and mix of Cool and West Coast jazz, Time Out was the first jazz album to sell over a million copies and produced a single, ‘Take Five’ that became the first jazz single to sell over a million copies. Brubeck described his saxophone player Paul Desmond’s sound as “like a dry martini”. You’ll want to ice up a glass and pour yourself another with each listen to this enduring jazz mainstay.\n- John Coltrane and Johnny Hartman: John Coltrane and Johnny Hartman (1963) is a reluctant jazz ballad summit of giants. Johnny Hartman initially resisted the idea of recording an album with John Coltrane, believing they wouldn’t complement one another musically. Following an after-hours session with Coltrane and pianist McCoy Tyner, they agreed to work together and went in to the studio to record their self-title album that contained the definitive versions of ‘Lush Life’, ‘They Say It’s Wonderful’, and ‘My One and Only Love.’ This is an absolute essential album.\n- Billie Holiday: Lady in Satin (1958) Holiday’s album of Great American Songbook standards  - lushly arranged around her abused, fragile, but powerfully rhythmic voice - is a testament to her professional powers of persuasion and artistic willpower in what turned out to be the last year of a 44-yr life. She told her producers she wanted “a pretty album, something delicate.” They paid her $150 a side, in advance. Well, she gave them their money’s worth…and then some. Essential.",

        "evidence": "Bidirectional Encoder Representations from Transformers (BERT) is a novel Transformer BIBREF0 model, which recently achieved state-of-the-art performance in several language understanding tasks, such as question answering, natural language inference, semantic similarity, sentiment analysis, and others BIBREF1. While well-suited to dealing with relatively short sequences, Transformers suffer from a major issue that hinders their applicability in classification of long sequences, i.e. they are able to consume only a limited context of symbols as their input BIBREF2.\nThere are several natural language (NLP) processing tasks that involve such long sequences. Of particular interest are topic identification of spoken conversations BIBREF3, BIBREF4, BIBREF5 and call center customer satisfaction prediction BIBREF6, BIBREF7, BIBREF8, BIBREF9. Call center conversations, while usually quite short and to the point, often involve agents trying to solve very complex issues that the customers experience, resulting in some calls taking even an hour or more. For speech analytics purposes, these calls are typically transcribed using an automatic speech recognition (ASR) system, and processed in textual representations further down the NLP pipeline. These transcripts sometimes exceed the length of 5000 words. Furthermore, temporal information might play an important role in tasks like CSAT. For example, a customer may be angry at the beginning of the call, but after her issue is resolved, she would be very satisfied with the way it was handled. Therefore, simple bag of words models, or any model that does not include temporal dependencies between the inputs, may not be well-suited to handle this category of tasks. This motivates us to employ model such as BERT in this task.\nIn this paper, we propose a method that builds upon BERT's architecture. We split the input text sequence into shorter segments in order to obtain a representation for each of them using BERT. Then, we use either a recurrent LSTM BIBREF10 network, or another Transformer, to perform the actual classification. We call these techniques Recurrence over BERT (RoBERT) and Transformer over BERT (ToBERT). Given that these models introduce a hierarchy of representations (segment-wise and document-wise), we refer to them as Hierarchical Transformers. To the best of our knowledge, no attempt has been done before to use the Transformer architecture for classification of such long sequences.\nOur novel contributions are:\nTwo extensions - RoBERT and ToBERT - to the BERT model, which enable its application in classification of long texts by performing segmentation and using another layer on top of the segment representations.\nState-of-the-art results on the Fisher topic classification task.\nSignificant improvement on the CSAT prediction task over the MS-CNN model.\nIn this paper, we propose a method that builds upon BERT’s architecture.

It is an example of cannibalization.\nThe term alludes to the Osborne Computer Corporation, whose second product did not become available until more than a year after it was announced. The company's subsequent bankruptcy was widely blamed on reduced sales after the announcement.\nThe Osborne Effect states that prematurely discussing future, unavailable products damages sales of existing products. The name comes from the planned replacement of the Osborne 1, an early personal computer first sold by the Osborne Computer Corporation in 1981. In 1983, founder Adam Osborne pre-announced several next-generation computer models (the Osborne Executive and Osborne Vixen), which were only prototypes, highlighting the fact that they would outperform the existing model as the prototypes dramatically cut down assembly time. A widely held belief was that sales of the Osborne 1 fell sharply as customers anticipated those more advanced systems, leading to a sales decline from which Osborne Computer was unable to recover. This belief appeared in the media almost immediately after the company's September 1983 bankruptcy:\n\nTo give the jazzy $2,495 Osborne Executive a running start, Adam began orchestrating publicity early in 1983. We, along with many other magazines, were shown the machine in locked hotel rooms. We were required not to have anything in print about it until the planned release date in mid-April. As far as we know, nothing did appear in print, but dealers heard about the plans and cancelled orders for the Osborne 1 in droves. In early April, Osborne told dealers he would be showing them the machine on a one-week tour the week of 17 April, and emphasized that the new machine was not a competitor for the Osborne 1. But dealers didn't react the way Osborne expected; said Osborne, \"All of them just cancelled their orders for the Osborne 1.\"\n\nOsborne reacted by drastically cutting prices on the Osborne 1 in an effort to stimulate cash flow. But nothing seemed to work, and for several months sales were practically non-existent.\n\nPre-announcement is done for several reasons: to reassure current customers that there is improvement or lower cost coming, to increase the interest of the media and investors in the company's future prospects, and to intimidate or confuse competitors. When done correctly, the sales or cash flow impact to the company is minimal, with the revenue drop for the current product being offset by orders or completed sales of the new product as it becomes available. However, when the Osborne effect occurs, the quantity of unsold goods increases and the company must react by discounting and/or lowering production of the current product, both of which depress cash flow.",

        "evidence": "Events are a kind of important objective information of the world. Structuralizing and representing such information as machine-readable knowledge are crucial to artificial intelligence BIBREF0, BIBREF1. The main idea is to learn distributed representations for structured events (i.e. event embeddings) from text, and use them as the basis to induce textual features for downstream applications, such as script event prediction and stock market prediction.\nParameterized additive models are among the most widely used for learning distributed event representations in prior work BIBREF2, BIBREF3, which passes the concatenation or addition of event arguments' word embeddings to a parameterized function. The function maps the summed vectors into an event embedding space. Furthermore, BIBREF4 ding2015deep and BIBREF5 weber2018event propose using neural tensor networks to perform semantic composition of event arguments, which can better capture the interactions between event arguments.\nThis line of work only captures shallow event semantics, which is not capable of distinguishing events with subtle differences. On the one hand, the obtained event embeddings cannot capture the relationship between events that are syntactically or semantically similar, if they do not share similar word vectors. For example, as shown in Figure FIGREF2 (a), “PersonX threw bomb” and “PersonZ attacked embassy”. On the other hand, two events with similar word embeddings may have similar embeddings despite that they are quite unrelated, for example, as shown in Figure FIGREF2 (b), “PersonX broke record” and “PersonY broke vase”. Note that in this paper, similar events generally refer to events with strong semantic relationships rather than just the same events.\nOne important reason for the problem is the lack of the external commonsense knowledge about the mental state of event participants when learning the objective event representations. In Figure FIGREF2 (a), two event participants “PersonY” and “PersonZ” may carry out a terrorist attack, and hence, they have the same intent: “to bloodshed”, which can help representation learning model maps two events into the neighbor vector space. In Figure FIGREF2 (b), a change to a single argument leads to a large semantic shift in the event representations, as the change of an argument can result in different emotions of event participants. Who “broke the record” is likely to be happy, while, who “broke a vase” may be sad. Hence, intent and sentiment can be used to learn more fine-grained semantic features for event embeddings.\nSuch commonsense knowledge is not explicitly expressed but can be found in a knowledge base such as Event2Mind BIBREF6 and ATOMIC BIBREF7. Thus, we aim to incorporate the external commonsense knowledge, i.e., intent and sentiment, into the learning process to generate better event representations. Specifically, we propose a simple and effective model to jointly embed events, intents and emotions into the same vector space. A neural tensor network is used to learn baseline event embeddings, and we define a corresponding loss function to incorporate intent and sentiment information.\nExtensive experiments show that incorporating external commonsense knowledge brings promising improvements to event embeddings, achieving 78% and 200% improvements on hard similarity small and big dataset, respectively. With better embeddings, we can achieve superior performances on script event prediction and stock market prediction compared to state-of-the-art baseline methods.\nUnderstanding events requires effective representations that contain commonsense knowledge. High-quality event representations are valuable for many NLP downstream applications. This paper proposed a simple and effective framework to incorporate commonsense knowledge into the learning process of event embeddings. Experimental results on event similarity, script event prediction and stock prediction showed that commonsense knowledge enhanced event embeddings can improve the quality of event representations and benefit the downstream applications.\nEvents are a kind of important objective information of the world.

        "evidence": "Table-to-text generation is an important and challenging task in natural language processing, which aims to produce the summarization of numerical table BIBREF0, BIBREF1. The related methods can be empirically divided into two categories, pipeline model and end-to-end model. The former consists of content selection, document planning and realisation, mainly for early industrial applications, such as weather forecasting and medical monitoring, etc. The latter generates text directly from the table through a standard neural encoder-decoder framework to avoid error propagation and has achieved remarkable progress. In this paper, we particularly focus on exploring how to improve the performance of neural methods on table-to-text generation.\nRecently, ROTOWIRE, which provides tables of NBA players' and teams' statistics with a descriptive summary, has drawn increasing attention from academic community. Figure FIGREF1 shows an example of parts of a game's statistics and its corresponding computer generated summary. We can see that the tables has a formal structure including table row header, table column header and table cells. “Al Jefferson” is a table row header that represents a player, “PTS” is a table column header indicating the column contains player's score and “18” is the value of the table cell, that is, Al Jefferson scored 18 points. Several related models have been proposed . They typically encode the table's records separately or as a long sequence and generate a long descriptive summary by a standard Seq2Seq decoder with some modifications. Wiseman explored two types of copy mechanism and found conditional copy model BIBREF3 perform better . Puduppully enhanced content selection ability by explicitly selecting and planning relevant records. Li improved the precision of describing data records in the generated texts by generating a template at first and filling in slots via copy mechanism. Nie utilized results from pre-executed operations to improve the fidelity of generated texts. However, we claim that their encoding of tables as sets of records or a long sequence is not suitable. Because (1) the table consists of multiple players and different types of information as shown in Figure FIGREF1. The earlier encoding approaches only considered the table as sets of records or one dimensional sequence, which would lose the information of other (column) dimension. (2) the table cell consists of time-series data which change over time. That is to say, sometimes historical data can help the model select content. Moreover, when a human writes a basketball report, he will not only focus on the players' outstanding performance in the current match, but also summarize players' performance in recent matches. Lets take Figure FIGREF1 again. Not only do the gold texts mention Al Jefferson's great performance in this match, it also states that “It was the second time in the last three games he's posted a double-double”. Also gold texts summarize John Wall's “double-double” performance in the similar way. Summarizing a player's performance in recent matches requires the modeling of table cell with respect to its historical data (time dimension) which is absent in baseline model. Although baseline model Conditional Copy (CC) tries to summarize it for Gerald Henderson, it clearly produce wrong statements since he didn't get “double-double” in this match.\nTo address the aforementioned problems, we present a hierarchical encoder to simultaneously model row, column and time dimension information. In detail, our model is divided into three layers. The first layer is used to learn the representation of the table cell. Specifically, we employ three self-attention models to obtain three representations of the table cell in its row, column and time dimension. Then, in the second layer, we design a record fusion gate to identify the more important representation from those three dimension and combine them into a dense vector. In the third layer, we use mean pooling method to merge the previously obtained table cell representations in the same row into the representation of the table's row. Then, we use self-attention with content selection gate BIBREF4 to filter unimportant rows' information. To the best of our knowledge, this is the first work on neural table-to-text generation via modeling column and time dimension information so far. We conducted experiments on ROTOWIRE. Results show that our model outperforms existing systems, improving baseline BLEU from 14.19 to 16.85 ($+18.75\\%$), P% of relation generation (RG) from 74.80 to 91.46 ($+22.27\\%$), F1% of content selection (CS) from 32.49 to 41.21 ($+26.84\\%$) and content ordering (CO) from 15.42 to 20.86 ($+35.28\\%$) on test set. It also exceeds the state-of-the-art model in terms of those metrics.\nThe first layer is used to learn the representation of the table cell.  Specifically, we employ three self-attention models to obtain three representations of the table cell in its row, column and time dimension.  Then, in the second layer, we design a record fusion gate to identify the more important representation from those three dimension and combine them into a dense vector.

        "evidence": "Automatic classification of sentiment has mainly focused on categorizing tweets in either two (binary sentiment analysis) or three (ternary sentiment analysis) categories BIBREF0 . In this work we study the problem of fine-grained sentiment classification where tweets are classified according to a five-point scale ranging from VeryNegative to VeryPositive. To illustrate this, Table TABREF3 presents examples of tweets associated with each of these categories. Five-point scales are widely adopted in review sites like Amazon and TripAdvisor, where a user's sentiment is ordered with respect to its intensity. From a sentiment analysis perspective, this defines a classification problem with five categories. In particular, Sebastiani et al. BIBREF1 defined such classification problems whose categories are explicitly ordered to be ordinal classification problems. To account for the ordering of the categories, learners are penalized according to how far from the true class their predictions are.\nAlthough considering different scales, the various settings of sentiment classification are related. First, one may use the same feature extraction and engineering approaches to represent the text spans such as word membership in lexicons, morpho-syntactic statistics like punctuation or elongated word counts BIBREF2 , BIBREF3 . Second, one would expect that knowledge from one task can be transfered to the others and this would benefit the performance. Knowing that a tweet is “Positive” in the ternary setting narrows the classification decision between the VeryPositive and Positive categories in the fine-grained setting. From a research perspective this raises the question of whether and how one may benefit when tackling such related tasks and how one can transfer knowledge from one task to another during the training phase.\nOur focus in this work is to exploit the relation between the sentiment classification settings and demonstrate the benefits stemming from combining them. To this end, we propose to formulate the different classification problems as a multitask learning problem and jointly learn them. Multitask learning BIBREF4 has shown great potential in various domains and its benefits have been empirically validated BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 using different types of data and learning approaches. An important benefit of multitask learning is that it provides an elegant way to access resources developed for similar tasks. By jointly learning correlated tasks, the amount of usable data increases. For instance, while for ternary classification one can label data using distant supervision with emoticons BIBREF9 , there is no straightforward way to do so for the fine-grained problem. However, the latter can benefit indirectly, if the ternary and fine-grained tasks are learned jointly.\nThe research question that the paper attempts to answer is the following: Can twitter sentiment classification problems, and fine-grained sentiment classification in particular, benefit from multitask learning? To answer the question, the paper brings the following two main contributions: (i) we show how jointly learning the ternary and fine-grained sentiment classification problems in a multitask setting improves the state-of-the-art performance, and (ii) we demonstrate that recurrent neural networks outperform models previously proposed without access to huge corpora while being flexible to incorporate different sources of data.\nAn important benefit of multitask learning is that it provides an elegant way to access resources developed for similar tasks.",

In each case, a transversal is found and the summary is formed by extracting and aggregating the associated sentences. Algorithm \"Detection of hypergraph transversals for text summarization\" is based on an adaptation of an algorithm presented in BIBREF30 for the maximization of submodular functions under a Knaspack constraint. It is our primary transversal-based summarization model, and we refer to it as the method of Transversal Summarization with Target Length (TL-TranSum algorithm). Algorithm \"Detection of hypergraph transversals for text summarization\" is an application of the algorithm presented in BIBREF20 for solving the submodular set covering problem.

Both algorithms produce transversals by iteratively appending the node inducing the largest increase in the total weight of the covered hyperedges relative to the node weight.

The Rays compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. Since its inception, the team's home venue has been Tropicana Field.\n\nFollowing nearly three decades of unsuccessfully trying to gain an expansion franchise or enticing existing teams to relocate to the Tampa Bay area, an ownership group led by Vince Naimoli was approved on March 9, 1995. The team began play as the Tampa Bay Devil Rays in the 1998 Major League Baseball season.\n\nThe team's first decade of play was marked by futility; they finished in last place in the AL East in all but the 2004 season, when they finished second to last. Following the 2007 season, Stuart Sternberg, who had purchased controlling interest in the team from Vince Naimoli two years earlier, changed the team's name from \"Devil Rays\" to \"Rays\", now meaning both a manta ray and a ray of sunshine; a manta ray logo appears on the uniform sleeves while a sunburst appears on the uniform front. The 2008 season saw the Rays post their first winning season, their first AL East championship, and their first American League pennant (defeating the rival Boston Red Sox in the ALCS), though they lost to the Philadelphia Phillies in that year's World Series. Since then, the Rays have played in the postseason seven more times, winning the American League pennant again in 2020 and losing to the Los Angeles Dodgers in that year's World Series.\n\nThe Tampa Bay Rays' chief rivals are the Boston Red Sox and the New York Yankees, which also play in the AL East. Regarding the former, there have been several notable on-field incidents. The Rays also have an in-state interleague rivalry with the National League (NL)'s Miami Marlins (originally the Florida Marlins), whom they play in the Citrus Series.\n\nThrough 2022, the Rays' all-time record is 1,912–2,034 (.485)",

There were various governing arrangements provided by the AoC, but the most important was protecting the power or sovereignty of the states.  The state would not have ratified the AoC if the federal government did not guarantee the powers of the states. The AoC defined a federal government with a unicameral legislature (one vote per state).  This legislation had the following powers: declare war, conduct “foreign or commercial relations with other countries” (i.e. treaties), and executive functions that would be carried out by legislative committees. It also “suggested a federal court system”.  This federal government was to be funded by the states.\nThough it provided these powers to the federal government, there were inherent weaknesses built into the federal government. First, there was no way for the legislature to enforce its decisions. Second, a declared war or commercial treaty required the consent of at least 9 states. Even if a war was approved, there was no federal army, only state militias. Third, the federal government relied on the states for funding.  If the states didn’t like legislation passed, they could simply withhold funding. Fourth, amendments to the AoC required the unanimous agreement of all thirteen states.  A realization came that these weaknesses inhibited the governing ability of the federal government.  This set the stage for dropping the AoC, which then lead to the current Constitution of the United States.",

        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children’s Book test but more than 60 times larger1 to enable training larger models even in the domain of text comprehension.

The downloaded data cover 175 communal, cantonal and national elections between 2011 and 2020.\nAll candidates in an election who participate in Smartvote are asked the same set of questions, but depending on the locale they see translated versions of the questions. They can answer each question with either `yes', `rather yes', `rather no', or `no'. They can supplement each answer with a comment of at most 500 characters.\nThe questions asked on Smartvote have been edited by a team of political scientists. They are intended to cover a broad range of political issues relevant at the time of the election. A detailed documentation of the design of Smartvote and the editing process of the questions is provided by BIBREF12.\nWe merged the two labels on each pole into a single label: `yes' and `rather yes' were combined into `favor'; `rather no', or `no' into `against`. This improves the consistency of the data and the comparability to previous stance detection datasets.\nWe did not further preprocess the text of the comments.\nAs the API does not provide the language of comments, we employed a language identifier to automatically annotate this information. We used the langdetect library BIBREF13. For each responder we classified all the comments jointly, assuming that responders did not switch code during the answering of the questionnaire.\nWe applied the identifier in a two-step approach. In the first run we allowed the identifier to output all 55 languages that it supports out of the box, plus Romansh, the fourth official language in Switzerland. We found that no Romansh comments were detected and that all unexpected outputs were misclassifications of German, French or Italian comments. We further concluded that little or no Swiss German comments are in the dataset: If they were, some of them would have manifested themselves in the form of misclassifications (e.g. as Dutch).\nIn the second run, drawing from these conclusions, we restricted the identifier's output to English, French, German and Italian.\nWe pre-filtered the questions and answers to improve the quality of the dataset. To keep the domain of the data surveyable, we set a focus on national-level questions. Therefore, all questions and corresponding answers pertaining to national elections were included.\nIn the context of communal and cantonal elections, candidates have answered both local questions and a subset of the national questions. Of those elections, we only considered answers to the questions that also had been asked in a national election. Furthermore, they were only used to augment the training set while the validation and test sets were restricted to answers from national elections.\nWe discarded the less than 20 comments classified as English. Furthermore, instances that met any of the following conditions were filtered from the dataset:\nQuestion is not a closed question or does not address a clearly defined political issue.\nNo comment was submitted by the candidate or the comment is shorter than 50 characters.\nComment starts with “but” or a similar indicator that the comment is not a self-contained statement.\nComment contains a URL.\nIn total, a fifth of the original comments were filtered out.\nThe questions have been organized by the Smartvote editors into categories (such as “Economy”). We further consolidated the pre-defined categories into 12 broad topics (Table TABREF7).\nThe dataset is shared under a CC BY-NC 4.0 license. Copyright remains with www.smartvote.ch.\nGiven the sensitive nature of the data, we increase the anonymity of the data by hashing the respondents' IDs.

        "question": "What dataset is used to train the model?",
        "answer": "A dataset that contains data from Wikipedia infobox",
        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nWe experiment with the WIKIBIO dataset (Lebret et al., 2016) which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words.",

        "evidence": "As an essential part of a task-oriented dialogue system BIBREF0 , the task of natural language generation (NLG) is to produce a natural language utterance containing the desired information given a semantic representation consisting of dialogue act types with a set of slot-value pairs. Conventional methods using hand-crafted rules often generates monotonic utterances and it requires substantial amount of human engineering work. Recently, various neural approaches BIBREF1 , BIBREF2 , BIBREF3 have been proposed to generate accurate, natural and diverse utterances. However, these methods are typically developed for particular domains. Moreover, they are often data-intensive to train. The high annotation cost prevents developers to build their own NLG component from scratch. Therefore, it is extremely useful to train a NLG model that can be generalized to other NLG domains or tasks with a reasonable amount of annotated data. This is referred to low-resource NLG task in this paper.\nRecently, some methods have been proposed for low-resource NLG tasks. Apart from the simple data augmentation trick BIBREF4 , specialized model architectures, including conditional variational auto-encoders (CVAEs, BIBREF3 , BIBREF5 , BIBREF6 ) and adversarial domain adaptation critics BIBREF5 , have been proposed to learn domain-invariant representations. Although promising results were reported, we found that datasets used by these methods are simple which tend to enumerate many slots and values in an utterance without much linguistic variations. As a consequence, over-fitting the slots and values in the low-resource target domain could even outperform those versions trained with rich source domain examples BIBREF6 . Fortunately, there is a new large-scale dialog dataset (MultiWoz, BIBREF7 ) that contains a great variety of domains and linguistic patterns that allows us to conduct extensive and meaningful experimental analysis for low-resource NLG tasks.\nIn this paper, instead of casting the problem as model-based approaches, we propose a generalized optimization-based meta-learning approach to directly enhance the optimization procedure for the low-resource NLG task. We start by arguing that a recently proposed model-agnostic meta-learning algorithm (MAML, BIBREF8 ) is a nice fit to the low-resource NLG task. Then, we proposed a generalized NLG algorithm called Meta-NLG based on MAML by viewing languages in different domains or dialog act types as separate Meta NLG tasks. Following the essence of MAML, the goal of Meta-NLG is to learn a better initialization of model parameters that facilitates fast adaptation to new low-resource NLG scenarios. As Meta-NLG is model-agnostic as long as the model can be optimized by gradient descent, we could apply it to any existing NLG models to optimize them in a way that adapt better and faster to new low-resource tasks.\nThe main contribution of this paper is two-fold:\nThen, we proposed a generalized NLG algorithm called Meta-NLG based on MAML by viewing languages in different domains or dialog act types as separate Meta NLG tasks.",

        "question": "Are there no experimental results? Even not on MNIST or a toy example to show that the theoretical findings correlate with empirical observations",
        "answer": "Thank you very much for pointing out the issue. As a first step towards understanding how the theoretical findings are valid for empirical situations, we have numerically tested the Gausssian mixture input with various mean values.  We have found that cRelu STE is similar to the population gradient, while id/Relu STEs shows completely different behavior as shown in Fig.1. The behaviors are the same as what we discussed theoretically.",
        "evidence": "In the quantized network, its gradient shows vanishing except for nondifferentiable points. The network thus cannot be learned by the standard backpropagation, so that an alternative approach called Straight Through Estimator (STE), which replaces the part of the gradient with a simple differentiable function, is used. While STE is known to work well for learning the quantized network empirically, it has not been established theoretically. A recent study by Yin et al. (2019) has provided theoretical support for STE. However, its justification is still limited to the model in the one-hidden layer network with the binary activation where Gaussian generates the input data, and the true labels are output from the teacher network with the same binary network architecture. In this paper, we discuss the effectiveness of STEs in more general situations without assuming the shape of the input distribution and the labels. By considering the scale symmetry of the network and specific properties of the STEs, we find that STE with clipped Relu is superior to STEs with identity function and vanilla Relu. The clipped Relu STE, which breaks the scale symmetry, may pick up one of the local minima degenerated in scales, while the identity STE and vanilla Relu STE, which keep the scale symmetry, may not pick it up. To confirm this observation, we further present an analysis of a simple misspecified model as an example. We find that all the stationary points are identical with the vanishing points of the cRelu STE gradient, while some of them are not identical with the vanishing points of the identity and Relu STE. Finally we have numerically confirmed the observation for the mixture Gaussian model with various teacher network.\nTo confirm our conjecture in more general case, we have numerically studied the Gaussian mixture input with various mean values. As teacher networks, we have tested tanh-type and sin-type as well as Relu-type. For all the examined setups, cRelu STE behaves like the population gradient, while id/Relu STEs show qualitatively different behaviors as described below. To calculate the population loss and STE gradients, we have generated the mixture Gaussian samples and have taken their average. The population gradient has been obtained by calculating the finite difference of the population loss. We have demonstrated the back propagation with learning rate η = 0.01 given in Algorithm 1.\nShown in Fig. are the results of ten mixture Gaussian input with random mean values for each components of Z. We employed m = 20, n = 25, and the tanh-type teacher network. We find that the population gradient and cRelu STE show similar results, while id/Relu STEs are completely different. This indicates cRelu STE is less biased than id/Relu STEs.\nIn the case of id/Relu STEs, at early steps up to around 500 step, |w| decreases around the magnitude of the update quantity, so that it begins to oscillate. Then it escapes the oscillation, and the loss function shows the convergence to a point different from the local minimum achieved by population gradient, while |w| becomes larger and larger due to their scale invariance. Interestingly, the values of the loss function are small compared to the one obtained by population gradient, which implies that id/Relu STEs avoid being trapped in the local solution due to their large bias. However, note that even at that point, the magnitude of w continues to grow and eventually become numerically unstable.\nFigure: Numerical results of the back-propagation by population gradient and three STEs. We generate 10000 samples which follow ten mixture Gaussian input with random mean values. We employ the tanh-type teacher network.\nWe find that all the stationary points are identical with the vanishing points of the cRelu STE gradient, while some of them are not identical with the vanishing points of the identity and Relu STE. Finally we have numerically confirmed the observation for the mixture Gaussian model with various teacher network.****We find that the population gradient and cRelu STE show similar results, while id/Relu STEs are completely different.

        "question": "Have you heard of Doleshwor Mahadeva temple?",
        "evidence": "Doleshwor Mahadeva (Nepali: डोलेश्वर महादेव) is a Hindu Temple of Lord Shiva located in Suryabinayak, south eastern part of Bhaktapur District, Nepal, and is believed to be the head part of Kedarnath temple located in Uttarakhand, India.\n\nHistory\nFor 4000 years people have been searching for the head of the Panch Kedar temples, a bull who was Shiva in reality, who assumed the shape of a bull to avoid the five Pandava brothers, the heroes of the Mahabharat. The legend goes back to the fabled battle of Kurukshetra fought between the five Pandava brothers and their cousins, the 100 Kaurava brothers, which is the pivot of the Mahabharata. Many folk legends related to the Garhwal region, Lord Shiva and the creation of the Panch Kedar temples are narrated.\n\nA folk legend about Panch Kedar relates to the Pandavas, the heroes of the Hindu epic Mahabharata. The Pandavas defeated and slayed their cousins — the Kauravas in the epic Kurukshetra war. They wished to atone for the sins of committing fratricide (gotra hatya) and Brāhmanahatya (killing of Brahmins — the priest class) during the war. Thus, they handed over the reins of their kingdom to their kin and left in search of lord Shiva and to seek his blessings. First, they went to the holy city of Varanasi (Kashi), believed to be Shiva's favourite city and known for its Kashi Vishwanath Temple. But, Shiva wanted to avoid them as he was deeply incensed by the death and dishonesty at the Kurukshetra war and was, therefore, insensitive to Pandavas' prayers. Therefore, he assumed the form of a bull (Nandi) and hid in the Garhwal region.\n\nNot finding Shiva in Varanasi, the Pandavas went to Garhwal Himalayas. Bhima, the second of the five Pandava brothers, then standing astride two mountains started to look for Shiva. He saw a bull grazing near Guptakashi (“hidden Kashi” — the name derived from the hiding act of Shiva). Bhima immediately recognized the bull to be Shiva. Bhima caught hold of the bull by its tail and hind legs. But the bull-formed Shiva disappeared into the ground to later reappear in parts, with the hump raising in Kedarnath, the arms appearing in Tungnath, the face showing up at Rudranath, the nabhi (navel) and stomach surfacing in Madhyamaheshwar and the hair appearing in Kalpeshwar. The Pandavas pleased with this reappearance in five different forms, built temples at the five places for venerating and worshipping Shiva. The Pandavas were thus freed from their sins. It is also believed that the fore portions of Shiva appeared at Doleshwor Mahadeva Temple, Bhaktapur district Nepal.\n\nA variant of the tale credits Bhima of not only catching the bull, but also stopping it from disappearing. Consequently, the bull was torn asunder into five parts and appeared at five locations in the Kedar Khand of Garhwal region of the Himalayas. After building the Panch Kedar Temples, the Pandavas meditated at Kedarnath for salvation, performed yagna (fire sacrifice) and then through the heavenly path called the Mahapanth (also called Swargarohini), attained heaven or salvation.[citation needed]. The Panch Kedar Temples are constructed in the North-Indian Himalayan Temple architecture with the Kedarnath, Tungnath and Madhyamaheshwar temples looking similar.\n\nAfter completing the pilgrimage of Lord Shiva's darshan at the Panch Kedar Temples, it is an unwritten religious rite to visit Lord Vishnu at the Badrinath Temple, as a final affirmatory proof by the devotee that he has sought blessings of Lord Shiva.\n\nResearch and findings\nThe Hindu activist Bharat Jangam had been researching and claiming that Doleshwar Mahadev is the head part of Kedarnath based on the surprising links between Kedarnath and Doleshwor. The Sculptures of Shive found in both shrines are 4,000 years old. Even a stone scripture found in Doleshwor was written in Sanskrit and Old Nepalese. The priests in both shrines are selected from India's southern states of Karnataka, Andhra Pradesh, Kerala and Tamil Nadu. Both priests affix the word ‘ling’ after their names to convey their proximity to the god as his worshipper and both temples have a cluster of five Shiva shrines. The main deity of both priests is Birbhadra, a companion of Shiva, according to Hindu scriptures. \n\nRecognition\nOn August 22, 2009 the head priest of Kedarnath peeth Shree 1008 Jagat Guru Bheemashankarling Shivacharya unveiled the plaque claiming that Doleswore Mahadev, located in Jangam math Bhaktapur, is the head part of Shri Kedarnath. He performed Rudra Abhishek, a special worshipping at the Doleshwor temple situated in Sipadol village of Bhaktapur district. This is also mentioned in the inscription (Sheela Lekh) at Doleshwar Mahadev. Thousands of devotees have been thronging in the Doleswor Mahadev Temple.",

        "answer": "While this question continues to be debated by sports fans and pundits around the globe nearly every single day, usually the answer comes down to one of a handful of players: Michael Jordan, Kareem Abdul-Jabbar, LeBron James, or Bill Russell.\n\nMichael Jordan is the most common answer to this question. He won 6 championship rings, 5 MVP's and never lost an NBA Finals series. If he didn't take a two year hiatus from the NBA to play baseball, there is a good chance that he would have won 8 NBA championships in a row. Michael was a fantastic defender, and arguably the most relentless competitor that the NBA has ever seen. He was notorious for gambling on almost anything, and his iconic Air Jordan shoe is largely responsible for Nike's success as a global brand.\n\nKareem Abdul-Jabbar was, until recently, the NBA's all time leading scorer. He played 20 seasons in the NBA, was a 19-time All-Star, 6-time MVP, and a 6-time NBA champion. He was incredibly consistent throughout his entire career, and transcended the NBA as a civil rights activist, author and even an actor.\n\nLeBron James is the greatest NBA player of this generation. He is a five-time NBA champion, four-time MVP, and recently surpassed Kareem Abdul-Jabbar as the NBA's all time leading scorer. No player came in to the NBA with greater expectations, and somehow, LeBron surpassed them all. LeBron first made headlines at age 15, and many of his high school games were nationally televised. \n\nBill Russell was the ultimate teammate. In 13 seasons in the NBA he won 11 titles, all as a member of the Boston Celtics. During his last two seasons, he won the title as a Player/Coach, also becoming the first black coach to win an NBA title. Russell was a five-time MVP and 12-time NBA All Star, and is widely respected as the best defensive player of his era. He had a well-publicized rivalry with Wilt Chamberlain, but while Wilt chased stats, Bill made sure his team won. \n\nIn addition to these four, there have been many other amazing basketball players over the years, including modern stars like Stephen Curry, Kevin Durant, the late Kobe Bryant, Magic Johnson, Larry Bird and more. Debating who is the best player ever is part of what makes basketball so entertaining. So while most people may say that Michael Jordan is the greatest player ever, this debate will rage on for years to come as more and more stars enter the league and build their careers.",

        "answer": "Whole manual thesauri and multiword expressions.",
        "evidence": "Topic modeling approaches are unsupervised statistical algorithms that usually considers each document as a \"bag of words\". There were several attempts to enrich word-based topic models (=unigram topic models) with additional prior knowledge or multiword expressions.\nAndrzejewski et al. BIBREF5 incorporated knowledge by Must-Link and Cannot-Link primitives represented by a Dirichlet Forest prior. These primitives were then used in BIBREF6 , where similar words are encouraged to have similar topic distributions. However, all such methods incorporate knowledge in a hard and topic-independent way, which is a simplification since two words that are similar in one topic are not necessarily of equal importance for another topic.\nXie et al. BIBREF7 proposed a Markov Random Field regularized LDA model (MRF-LDA), which utilizes the external knowledge to improve the coherence of topic modeling. Within a document, if two words are labeled as similar according to the external knowledge, their latent topic nodes are connected by an undirected edge and a binary potential function is defined to encourage them to share the same topic label. Distributional similarity of words is calculated beforehand on a large text corpus.\nIn BIBREF8 , the authors gather so-called lexical relation sets (LR-sets) for word senses described in WordNet. The LR-sets include synonyms, antonyms and adjective-attribute related words. To adapt LR-sets to a specific domain corpus and to remove inappropriate lexical relations, the correlation matrix for word pairs in each LR-set is calculated. This matrix at the first step is used for filtrating inappropriate senses, then it is used to modify the initial LDA topic model according to the generalized Polya urn model described in BIBREF9 . The generalized Polya urn model boosts probabilities of related words in word-topic distributions.\nGao and Wen BIBREF10 presented Semantic Similarity-Enhanced Topic Model that accounts for corpus-specific word co-occurrence and word semantic similarity calculated on WordNet paths between corresponding synsets using the generalized Polya urn model. They apply their topic model for categorizing short texts.\nAll above-mentioned approaches on adding knowledge to topic models are limited to single words. Approaches using ngrams in topic models can be subdivided into two groups. The first group of methods tries to create a unified probabilistic model accounting unigrams and phrases. Bigram-based approaches include the Bigram Topic Model BIBREF11 and LDA Collocation Model BIBREF12 . In BIBREF13 the Topical N-Gram Model was proposed to allow the generation of ngrams based on the context. However, all these models are enough complex and hard to compute on real datasets.\nThe second group of methods is based on preliminary extraction of ngrams and their further use in topics generation. Initial studies of this approach used only bigrams BIBREF14 , BIBREF15 . Nokel and Loukachevitch BIBREF16 proposed the LDA-SIM algorithm, which integrates top-ranked ngrams and terms of information-retrieval thesauri into topic models (thesaurus relations were not utilized). They create similarity sets of expressions having the same word components and sum up frequencies of similarity set members if they co-occur in the same text.\nIn this paper we describe the approach to integrate whole manual thesauri into topic models together with multiword expressions.\nIn this paper we describe the approach to integrate whole manual thesauri into topic models together with multiword expressions.",

Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT contextual embedding.",

        "answer": "In the revised paper, we state these two assumptions and provide a brief justification for the same. The assumption of same number of components is a practical one that we make in order to not have to change the architecture of the MDN. Adding or removing components would require a change to the output layer of the MDN. Also, this assumption can be practically justified when the number of components is chosen to be sufficiently large. With a large number of components, the appearance or disappearance of a few clusters of data from the true data distribution can be compensated for by other components in the Gaussian mixture.",
        "evidence": "Consider the Gaussian mixtures corresponding to the source and target channel conditional densities, where θ c and θ c are the parameter vectors of the original and adapted MDN. Here µ i (x) ∈ R d is the mean vector, σ 2 i (x) ∈ R d + is the variance vector, and π i (x) ∈ [0, 1] is the prior probability (weight) of component i for the original mixture. We have assumed that the Gaussian components have a diagonal covariance matrix, with σ 2 i (x) being the diagonal elements 2 . The mixture weights are parameterized using the softmax function as π i (x) = e αi(x) / k j=1 e αj (x) , ∀i. The MDN simply predicts the un-normalized weights α i (x) ∈ R or the prior logits. The parameter vector of component i is defined as Affine and Inverse-Affine Feature Transfomations. Applying the above result to our MDN with k components, we define the affine feature transformation for a given symbol x and component i,\n(3)\nIt is straightforward to also define the inverse-affine transformation from y to y as\nFor the case of diagonal covariances, we constrain C i to be diagonal. These feature transformations will be used for aligning the target and source class-conditional distributions of the decoder input.\nParameter Transformations. The corresponding transformations between the source and target Gaussian mixture parameters for any symbol x ∈ X and component i ∈ [k] are given by\nwhere\n) is a diagonal scale matrix for the variances; and β i ∈ R and γ i ∈ R are the scale and offset for the prior logits.\nThe vector of all adaptation parameters to be optimized is defined as\n, where ψ T i contains the affine-transformation parameters from component i. The number of adaptation parameters (dimension of ψ) is given by k (d 2 + 2 d + 2). This is typically much smaller than the number of MDN parameters (weights and biases from all layers), even for shallow fully-connected NNs. In Fig., the adaptation layer mapping φ(x) to φ(x) basically implements the parameter transformations defined in Eq. ().\nAssumptions and Key Insight. The proposed adaptation of the MDN is based on the affinetransformation property of multivariate Gaussians, i.e., one can transform between any two multivariate Gaussians through an affine transformation. Assumption 1: The source and target Gaussian mixtures have the same number of components. This is a practical assumption we make in order to not have to change the architecture of the MDN. Adding or removing components would require a change to the output layer of the MDN. Also, this assumption can be practically justified when k is chosen to be sufficiently large. Assumption 2: The two mixtures have a one-to-one correspondence between the components. This assumption makes in mathematically convenient to derive a closed-form expression for the KL-divergence between two Gaussian mixtures, which would not be possible in the general case.\nBased on the above assumptions, we can formulate the MDN adaptation as an equivalent problem of finding the optimal set of affine transformations (one per-component) from the source to the target Gaussian mixture. This is a much smaller problem compared to optimizing the weights of all the MDN layers. Moreover, the affine transformations are bijective, allowing the feature and parameter mapping to be applied in the inverse direction. To reduce the possibility of the adapted MDN finding bad solutions due to the small-sample regime, we include a regularization term based on the KL-divergence (KLD) in the adaptation objective.\nAssumptions and Key Insight.

Stan's hurricane-related research has included developing and implementing significant improvements to one of the earlier numerical hurricane-track prediction models used by the National Hurricane Center and more recently, examining the various climatic factors which influence the variability of hurricane activity in the Atlantic from intraseasonal to multidecadal time scales. He has done extensive research into the physical mechanisms responsible for the connection between El Niño and Atlantic hurricane activity. He was the first author of the research report published in Science establishing the fact that the Atlantic hurricane basin has entered a multidecadal-scale era of greatly increased hurricane activity. The paper concluded that the increase in hurricane activity was due to natural climate fluctuations rather than from any long-term temperature trends (which some attribute to anthropogenic global warming).

Eastern-style sauce is vinegar and pepper-based, with no tomato whatsoever. Eastern sauce is mostly used as a seasoning after the cook (although it can also be used as a mop sauce while the hog is cooking). The coleslaw served with eastern-style uses mayonnaise (or whipped salad dressing) almost universally.\n\nLexington style\nLexington style barbecue (also called Piedmont or Western style) uses a red sauce, or \"dip\", made from vinegar, tomatoes, and usually red pepper flakes, along with other spices that vary from recipe to recipe.  It is most common in the Piedmont and western areas of the state. This style uses only the pork shoulder section of the pig. As with other styles of barbecue, the recipes vary widely, and can include many different ingredients, and range from slightly sweet to hot and spicy. The sauce also serves as the seasoning base for \"red slaw\" (also called \"barbecue slaw\"), which is coleslaw made by using Lexington-style barbecue sauce in place of mayonnaise. Hushpuppies are usually consumed with pork shoulder and slaw.\n\nPork ribs\nPork ribs are a common alternative to the two most common types of North Carolina barbecue and a variety of festivals and competitions are held annually. Baby back ribs, sometimes called top loin ribs, are short, succulent, well-marbled ribs cut from the center section of the loin.

        "question": "From what aspects does the way proposed in this paper evaluate the quality of the paper?",
        "answer": "Not only readability and reliability criteria, but also additional parameters testifying completeness of information and coherence with the content one expects from an article dealing with specific topics, plus sufficient insights for the reader to elaborate further on some argument.",
        "evidence": "As observed by a recent article of Nature News BIBREF0 , “Wikipedia is among the most frequently visited websites in the world and one of the most popular places to tap into the world's scientific and medical information\". Despite the huge amount of consultations, open issues still threaten a fully confident fruition of the popular online open encyclopedia.\nA first issue relates to the reliability of the information available: since Wikipedia can be edited by anyone, regardless of their level of expertise, this tends to erode the average reputation of the sources, and, consequently, the trustworthiness of the contents posted by those sources. In an attempt to fix this shortcoming, Wikipedia has recently enlisted the help of scientists to actively support the editing on Wikipedia BIBREF0 . Furthermore, lack of control may lead to the publication of fake Wikipedia pages, which distort the information by inserting, e.g., promotional articles and promotional external links. Fighting vandalism is one of the main goals of the Wikimedia Foundation, the nonprofit organization that supports Wikipedia: machine learning techniques have been considered to offer a service to “judge whether an edit was made in good faith or not\" BIBREF1 . Nonetheless, in the past recent time, malicious organisations have acted disruptively with purposes of extortion - see, e.g., the recent news on the uncovering of a blackmail network of accounts, which threatened celebrities with the menace of inserting offending information on their Wikipedia pages.\nSecondly, articles may suffer from readability issues: achieving a syntactical accuracy that helps the reader with a fluid reading experience is —quite obviously— a property which articles should fulfill. Traditionally, the literature has widely adopted well known criteria, as the “Flesch-Kincaid\" measure\" BIBREF2 , to automatically assess readability in textual documents. More recently, new techniques have been proposed too, for assessing the readability of natural languages (see, e.g., BIBREF3 for the Italian use case, BIBREF4 for the Swedish one, BIBREF5 for English).\nIn this paper, we face the quest for quality assessment of a Wikipedia article, in an automatic way that comprehends not only readability and reliability criteria, but also additional parameters testifying completeness of information and coherence with the content one expects from an article dealing with specific topics, plus sufficient insights for the reader to elaborate further on some argument. The notion of data quality we deal with in the paper is coherent with the one suggested by recent contributions (see, e.g., BIBREF6 ), which points out like the quality of Web information is strictly connected to the scope for which one needs such information.\nOur intuition is that groups of articles related to a specific topic and falling within specific scopes are intrinsically different from other groups on different topics within different scopes. We approach the article evaluation through machine learning techniques. Such techniques are not new to be employed for automatic evaluation of articles quality. As an example, the work in BIBREF7 exploits classification techniques based on structural and linguistic features of an article. Here, we enrich that model with novel features that are domain-specific. As a running scenario, we focus on the Wikipedia medical portal. Indeed, facing the problems of information quality and ensuring high and correct levels of informativeness is even more demanding when health aspects are involved. Recent statistics report that Internet users are increasingly searching the Web for health information, by consulting search engines, social networks, and specialised health portals, like that of Wikipedia. As pointed out by the 2014 Eurobarometer survey on European citizens' digital health literacy, around six out of ten respondents have used the Internet to search for health-related information. This means that, although the trend in digital health literacy is growing, there is also a demand for a qualified source where people can ask and find medical information which, to an extent, can provide the same level of familiarity and guarantees as those given by a doctor or a health professional.\nWe anticipate here that leveraging new domain-specific features is in line with this demand of articles quality. Moreover, as the outcomes of our experiments show, they effectively improve the classification results in the hard task of multi-class assessment, especially for those classes that other automatic approaches worst classify. Remarkably, our proposal is general enough to be easily extended to other domains, in addition to the medical one.\nSection \"Dataset\" first describes the structure of the articles present in the medical portal. Then, it gives details on the real data used in the experiments, which are indeed articles extracted from the medical portal and labeled according to the manual assessment by the Wikimedia project. Section \"Baseline: the actionable model\" briefly presents the actionable model in BIBREF7 : we adopt it as the baseline for our analysis. In Section \"The medical domain model\" , we present the domain-specific, medical model we newly adopt in this paper as an extension of the baseline. The extended model includes features specifically extracted from the medical domain. One novel feature is based on the article textual content. Section \"Bio-medical entities\" presents the process which its extraction relies on, with a non trivial analysis of natural language and domain knowledge. Section \"Experiments and results\" presents experiments and results, with a comparison of the baseline model with the new one. In Section \"Related work\" , we survey related work in the area and in Section \"Conclusions\" we conclude the paper.\nIn this paper, we face the quest for quality assessment of a Wikipedia article, in an automatic way that comprehends not only readability and reliability criteria, but also additional parameters testifying completeness of information and coherence with the content one expects from an article dealing with specific topics, plus sufficient insights for the reader to elaborate further on some argument.",

        "question": "What is the original idea of machine translation?",
        "answer": "The origin idea of machine translation is commonly connected with the work of Rene Descartes, i.e. to his idea of universal language.",
        "evidence": "In this paper, we are exploring the historical significance of Croatian machine translation research group. The group was active in 1950s, and it was conducted by Bulcsu Laszlo, Croatian linguist, who was a pioneer in machine translation during the 1950s in Yugoslavia.\nTo put the research of the Croatian group in the right context, we have to explore the origin of the idea of machine translation. The idea of machine translation is an old one, and its origin is commonly connected with the work of Rene Descartes, i.e. to his idea of universal language, as described in his letter to Mersenne from 20.xi.1629 BIBREF0. Descartes describes universal language as a simplified version of the language which will serve as an “interlanguage” for translation. That is, if we want to translate from English to Croatian, we will firstly translate from English to an “interlanguage”, and then from the “interlanguage” to Croatian. As described later in this paper, this idea had been implemented in the machine translation process, firstly in the Indonesian-to-Russian machine translation system created by Andreev, Kulagina and Melchuk from the early 1960s.\nIn modern times, the idea of machine translation was put forth by the philosopher and logician Yehoshua Bar-Hillel (most notably in BIBREF1 and BIBREF2), whose papers were studied by the Croatian group. Perhaps the most important unrealized point of contact between machine translation and cybernetics happened in the winter of 1950/51. In that period, Bar-Hillel met Rudolf Carnap in Chicago, who introduced to him the (new) idea of cybernetics. Also, Carnap gave him the contact details of his former teaching assistant, Walter Pitts, who was at that moment with Norbert Wiener at MIT and who was supposed to introduce him to Wiener, but the meeting never took place BIBREF3. Nevertheless, Bar-Hillel was to stay at MIT where he, inspired by cybernetics, would go to organize the first machine translation conference in the world in 1952 BIBREF3.\nThe idea of machine translation was a tempting idea in the 1950s. The main military interest in machine translation as an intelligence gathering tool (translation of scientific papers, daily press, technical reports, and everything the intelligence services could get their hands on) was sparked by the Soviet advance in nuclear technology, and would later be compounded by the success of Vostok 1 (termed by the USA as a “strategic surprise”). In the nuclear age, being able to read and understand what the other side was working on was of crucial importance BIBREF4. Machine translation was quickly absorbed in the program of the Dartmouth Summer Research Project on Artificial Intelligence in 1956 (where Artificial Intelligence as a field was born), as one of the five core fields of artificial intelligence (later to be known as natural language processing). One other field was included here, the “nerve nets” as they were known back then, today commonly known as artificial neural networks. What is also essential for our discussion is that the earliest programming language for artificial intelligence, Lisp, was invented in 1958 by John McCarthy BIBREF5. But let us take a closer look at the history of machine translation. In the USA, the first major wave of government and military funding for machine translation came in 1954, and the period of abundancy lasted until 1964, when the National Research Council established the Automatic Language Processing Advisory Committee (ALPAC), which was to assess the results of the ten years of intense funding. The findings were very negative, and funding was almost gone BIBREF4, hence the ALPAC report became the catalyst for the first “AI Winter”.\nOne of the first recorded attempts of producing a machine translation system in the USSR was in 1954 BIBREF6, and the attempt was applauded by the Communist party of the Soviet Union, by the USSR Committee for Science and Technology and the USSR Academy of Sciences. The source does not specify how this first system worked, but it does delineate that the major figures of machine translation of the time were N. Andreev of the Leningrad State University, O. Kulagina and I. Melchuk of the Steklov Mathematical Institute. There is information on an Indonesian-to-Russian machine translation system by Andreev, Kulagina and Melchuk from the early 1960s, but it is reported that the system was ultimately a failure, in the same way early USA systems were. The system had statistical elements set forth by Andreev, but the bulk was logical and knowledge-heavy processing put forth by Kulagina and Melchuk. The idea was to have a logical intermediate language, under the working name “Interlingua”, which was the connector of both natural languages, and was used to model common-sense human knowledge. For more details, see BIBREF6.\nIn the USSR, there were four major approaches to machine translation in the late 1950s BIBREF7. The first one was the research at the Institute for Precise Mechanics and Computational Technology of the USSR Academy of Sciences. Their approach was mostly experimental and not much different from today's empirical methods. They evaluated the majority of algorithms known at the time algorithms over meticulously prepared datasets, whose main strength was data cleaning, and by 1959 they have built a German-Russian machine translation prototype. The second approach, as noted by Mulić BIBREF7, was championed by the team at the Steklov Mathematical Institute of the USSR Academy of Sciences led by A. A. Reformatsky. Their approach was mainly logical, and they extended the theoretical ideas of Bar-Hillel BIBREF2 to build three algorithms: French-Russian, English-Russian and Hungarian-Russian. The third and perhaps the most successful approach was the one by A. A. Lyapunov, O. S. Kulagina and R. L. Dobrushin. Their efforts resulted in the formation of the Mathematical Linguistics Seminar at the Faculty of Philology in Moscow in 1956 and in Leningrad in 1957. Their approach was mainly information-theoretic (but they also tried logic-based approaches BIBREF7), which was considered cybernetic at that time. This was the main role model for the Croatian efforts from 1957 onwards. The fourth, and perhaps most influential, was the approach at the Experimental Laboratory of the Leningrad University championed by N. D. Andreev BIBREF7. Here, the algorithms for Indonesian-Russian, Arabic-Russian, Hindu-Russian, Japanese-Russian, Burmese-Russian, Norwegian-Russian, English-Russian, Spanish-Russian and Turkish-Russian were being built. The main approach of Andreev's group was to use an intermediary language, which would capture the meanings BIBREF7. It was an approach similar to KL-ONE, which would be introduced in the West much later (in 1985) by Brachman and Schmolze BIBREF8. It is also interesting to note that the Andreev group had a profound influence on the Czechoslovakian machine translation program BIBREF9, which unfortunately suffered a similar fate as the Yugoslav one due to the lack of funding.\nAndreev's approach was in a sense \"external\". The modelling would be statistical, but its purpose would not be to mimic the stochasticity of the human thought process, but rather to produce a working machine translation system. Kulagina and Melchuk disagreed with this approach as they thought that more of what is presently called \"philosophical logic\" was needed to model the human thought process at the symbolic level, and according to them, the formalization of the human thought process was a prerequisite for developing a machine translation system (cf. BIBREF6). We could speculate that sub-symbolic processing would have been acceptable too, since that approach is also rooted in philosophical logic as a way of formalizing human cognitive functions and is also \"internal\" in the same sense symbolic approaches are.\nThere were many other centers for research in machine translation: Gorkovsky University (Omsk), 1st Moscow Institute for Foreign Languages, Computing Centre of the Armenian SSR and at the Institute for Automatics and Telemechanics of the Georgian SSR BIBREF7. It is worthwhile to note that both the USA and the USSR had access to state-of-the-art computers, and the political support for the production of such systems meant that computers were made available to researchers in machine translation. However, the results were poor in the late 1950s, and a working system was yet to be shown. All work was therefore theoretical work implemented on a computer, which proved to be sub-optimal.\nThe idea of machine translation is an old one, and its origin is commonly connected with the work of Rene Descartes, i.e. to his idea of universal language, as described in his letter to Mersenne from 20.xi.1629 [5].",

Her team consist of her parents, three siblings, and her coach Ben Bryant: a disgraced, former competitive sailor. When on her boat, Ella's Pink Lady, Jessica communicates with the team via satellite phone.\n\nOn a test run, Jessica's boat is hit by a freighter that strayed off course. She didn't notice the oncoming ship because she forgot to turn on her alert system before going to bed.

Ben returns and advises her to alter the route, effectively abandoning her official circumnavigation. Jessica refuses to give up and choses to ride it out. The storm proves to be far more violent than the last one. The Pink Lady capsizes and is thrust 15 feet (4.5 meters) underwater. This sets off the boat's emergency locator beacon, and the team fears Jessica may have drowned.\n\nThe Pink Lady, however, resurfaces and rights herself.

The objective of the game is to score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is considered the world's most popular sport.\n\nThe game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 and maintained by the IFAB since 1886. The game is played with a football that is 68–70 cm (27–28 in) in circumference. The two teams compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. When the ball is in play, the players mainly use their feet, but may use any other part of their body, except for their hands or arms, to control, strike, or pass the ball. Only the goalkeepers may use their hands and arms, and only then within the penalty area. The team that has scored more goals at the end of the game is the winner. Depending on the format of the competition, an equal number of goals scored may result in a draw being declared, or the game goes into extra time or a penalty shootout.\n\nInternationally, association football is governed by FIFA. Under FIFA, there are six continental confederations: AFC, CAF, CONCACAF, CONMEBOL, OFC and UEFA.

        "answer": "An ill-trained attention module and thus hurting the performance.",
        "evidence": "Relation extraction (RE) is one of the most fundamental tasks in natural language processing, and its goal is to identify the relationship between a given pair of entities in a sentence. Typically, a large-scale training dataset with clean labels is required to train a reliable relation extraction model. However, it is time-consuming and labor-intensive to annotate such data by crowdsourcing. To overcome the lack of labeled training data, BIBREF0 mintz2009distant presents a distant supervision approach that automatically generates a large-scale, labeled training set by aligning entities in knowledge graph (e.g. Freebase BIBREF1) to corresponding entity mentions in natural language sentences. This approach is based on a strong assumption that, any sentence containing two entities should be labeled according to the relationship of the two entities on the given knowledge graph. However, this assumption does not always hold. Sometimes the same two entities in different sentences with various contexts cannot express a consistent relationship as described in the knowledge graph, which certainly results in wrongly labeled problem.\nTo alleviate the aformentioned problem, BIBREF2 riedel2010modeling proposes a multi-instance learning framework, which relaxes the strong assumption to expressed-at-least-one assumption. In plainer terms, this means any possible relation between two entities hold true in at least one distantly-labeled sentence rather than all of the them that contains those two entities. In particular, instead of generating a sentence-level label, this framework assigns a label to a bag of sentences containing a common entity pair, and the label is a relationship of the entity pair on knowledge graph. Recently, based on the labeled data at bag level, a line of works BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 under selective attention framework BIBREF5 let model implicitly focus on the correctly labeled sentence(s) by an attention mechanism and thus learn a stable and robust model from the noisy data.\nHowever, such selective attention framework is vulnerable to situations where a bag is merely comprised of one single sentence labeled; and what is worse, the only one sentence possibly expresses inconsistent relation information with the bag-level label. This scenario is not uncommon. For a popular distantly supervised relation extraction benchmark, e.g., NYT dataset BIBREF2, up to $80\\%$ of its training examples (i.e., bags) are one-sentence bags. From our data inspection, we randomly sample 100 one-sentence bags and find $35\\%$ of them is incorrectly labeled. Two examples of one-sentence bag are shown in Table TABREF1. These results indicate that, in training phrase the selective attention module is enforced to output a single-valued scalar for $80\\%$ examples, leading to an ill-trained attention module and thus hurting the performance.\nMotivated by aforementioned observations, in this paper, we propose a novel Selective Gate (SeG) framework for distantly supervised relation extraction. In the proposed framework, 1) we employ both the entity embeddings and relative position embeddings BIBREF8 for relation extraction, and an entity-aware embedding approach is proposed to dynamically integrate entity information into each word embedding, yielding more expressively-powerful representations for downstream modules; 2) to strengthen the capability of widely-used piecewise CNN (PCNN) BIBREF3 on capturing long-term dependency BIBREF9, we develop a light-weight self-attention BIBREF10, BIBREF11 mechanism to capture rich dependency information and consequently enhance the capability of neural network via producing complementary representation for PCNN; and 3) based on preceding versatile features, we design a selective gate to aggregate sentence-level representations into bag-level one and alleviate intrinsic issues appearing in selective attention.\nCompared to the baseline framework (i.e., selective attention for multi-instance learning), SeG is able to produce entity-aware embeddings and rich-contextual representations to facilitate downstream aggregation modules that stably learn from noisy training data. Moreover, SeG uses gate mechanism with pooling to overcome problem occurring in selective attention, which is caused by one-sentence bags. In addition, it still keeps a light-weight structure to ensure the scalability of this model.\nThe experiments and extensive ablation studies on New York Time dataset BIBREF2 show that our proposed framework achieves a new state-of-the-art performance regarding both AUC and top-n precision metrics for distantly supervised relation extraction task, and also verify the significance of each proposed module. Particularly, the proposed framework can achieve AUC of 0.51, which outperforms selective attention baseline by 0.14 and improves previous state-of-the-art approach by 0.09.\nThese results indicate that, in training phrase the selective attention module is enforced to output a single-valued scalar for 80% examples, leading to an illtrained attention module and thus hurting the performance",

Relevant features proposed in the literature span from microblogging artifacts including hashtags, emoticons BIBREF0 , BIBREF1 , intensifiers like all-caps words and character repetitions BIBREF2 , sentiment-topic features BIBREF3 , to the inclusion of polarity lexicons.\nThe objective of the work presented in this paper is the creation of sentiment polarity lexicons. They are word lists or phrase lists with positive and negative sentiment labels. Sentiment lexicons allow to increase the feature space with more relevant and generalizing characteristics of the input. Unfortunately, creating sentiment lexicons requires human expertise, is time consuming, and often results in limited coverage when dealing with new domains.\nIn the literature, it has been proposed to extend existing lexicons without supervision BIBREF4 , BIBREF5 , or to automatically translate existing lexicons from resourceful languages with statistical machine translation (SMT) systems BIBREF6 . While the former requires seed lexicons, the later are very interesting because they can automate the process of generating sentiment lexicons without any human expertise. But automatically translating sentiment lexicons leads to two problems: (1) out-of-vocabulary words, such as mis-spellings, morphological variants and slang, cannot be translated, and (2) machine translation performance strongly depends on available training resources such as bi-texts.\nIn this paper, we propose to apply the method proposed in BIBREF7 for automatically mapping word embeddings across languages and use them to translate sentiment lexicons only given a small, general bilingual dictionary. After creating monolingual word embeddings in the source and target language, we train a linear transform on the bilingual dictionary and apply that transform to words for which we don't have a translation.\nWe perform experiments on 3-class polarity classification in tweets, and report results on four different languages: French, Italian, Spanish and German. Existing English sentiment lexicons are translated to the target languages through the proposed approach, given gs trained on the respective Wikipedia of each language. Then, a SVM-based classifier is fed with lexicon features, comparing machine translation with embedding transfer.\nAfter presenting related work in Section SECREF2 , the extraction of word gs and their mapping across languages are detailed in Section SECREF3 .

In our learning framework, the spatial gradient computation must undergo the sampling procedure.\nWe name our gradient computation involving the sampling operation as the Pixel Conditioned Gradients and derive a closed-form solution, Differentiable Gradient Sampling (DGS), for handling forward and backward propagation. Figure(a) provides an illustration of our training pipeline. Each layer in our network tracks both the response of the layer as well as its spatial gradient w.r.t. (x, y, z). While it is well established to track the layer-wise spatial gradient for fully-connected (FC) layers or convolutions in existing works, tracking the spatial gradients and back-propagating the loss to the feature map pixels ϕ through the sampling module has not been studied. To this end, we derive the closed-form sampling scheme for tracking and propagating the spatial gradients ∂ϕ ∂x,y,z through the sampling layer. Background -2D Differentiable Sampling. Differentiably sampling pixel values from a grid of 2D feature map with the given pixel locations (i, j) is a common operation. Throughout our paper, we define the pixel coordinates in the Normalized Device Coordinate (NDC) system that ranges from -1 to 1. As illustrated in Fig., given the feature map ϕ and the sampling locations (i, j), the resulting sampled value ϕ(i, j) is\nPlease refer to Fig.(c) for the definitions of α, β and ϕ A , ϕ B , ϕ C , ϕ D . Without loss of generality we use bilinear interpolation. During training, the gradient from the loss can be back-propagated via\n2D Differentiable Gradient Sampling. Our learning framework (Sec. 3.1, Fig.(a)) requires the extension of the sampling capability from just the feature value response ϕ i,j to its spatial gradient ∇ i,j ϕ(i, j). During the forward and the backward propagation, both the sampled feature response ϕ i,j and its spatial gradient ∇ i,j ϕ(i, j) are recorded for further propagation (Fig.(e)):\nHence, during the forward pass, we compute the spatial gradient via Eq. 5 in addition to the existing value sampling (Eq. 3). During the backward pass, we compute the loss gradient over the spatial gradient via\nwhere w and h are the width and height of a pixel in NDC, s.t. w = 2/W and h = 2/H for the feature map with the size W × H.\n3D Differentiable Gradient Sampling. We now extend the sampling to 3D. We model the camera as the pin-hole camera. For any point (x, y, z) in the camera space, we seek for its projected 2D locations (i, j) based on the focal length\nDuring the backward propagation procedure, the DGS accumulates the gradient via Comparison with state-of-the-art approaches. We choose to compare to recent representative state-of-the-art approaches, including OccNet, DISN, CoReNet and D 2 IM-Net. Quantitative results are reported in Tab. 3 for the low-realism evaluation setting, and in Tab. 1 for the high-realism setting, where our results outperform all the state-of-the-art results in all the settings. Please refer to Sec. A for qualitative comparison, implementation details and the evaluation metrics.\nFor our low-realism evaluation setting, all the baseline approaches reported their results in the papers. For OccNet and DISN, the reported results are based on knowing the category canonical view prior, which demonstrates considerable privilege with respect to accuracy. Hence, we mark the results from the literature as OccNet-Privilege and DISN-Privilege (OccNet-Priv. and DISN-Priv. for short). Compared to their privileged setting, our results demonstrate superior results even without the category canonical view prior privilege. To further provide the the baseline results where these two approaches are without the category canonical view prior, we retrain their models with the released codes, and report the results in the \"OccNet\" and \"DISN\" row respectively. The results further provide evidence that the category canonical view prior demonstrates privilege on accuracy, as observed in.\nFor our high-realism evaluating setting, since the results for Occnet and DISN are not directly available from the paper, we retrain their model from the released codes (without the category canonical view prior) on the high-realism data provided by. We also retrain CoReNet using their released codes and obtain results better than reported in their original paper (61.5 as mIoU instead of 59.5). Our model still consistently outperforms all the baselines on almost all the categories. We emphasize that our comparison to CoReNet is a direct ablation comparison where we directly follow their experimental setup and model size. Furthermore, our approach only utilizes the closeto-surface occupancy labels, which is a subset of the whole occupancy labels for all the query point.\nOur model still outperforms the baseline and provides convincing evidence that our supervision loss function demonstrate better results than the original CoReNet approach. We attribute the superiority of our approach to our particular focus toward the difficult close-to-surface region similar to hard negative mining. Ablation Study. We further conduct ablation studies to further validate the importance of derived DGS module, via attempting work-around training methods without DGS. i) NoGrad -To test the performance of the baseline when only the surface data are provided, we train this ablation model in exactly the same way compared to its original model, with the only exceptions that only the near-surface points are equipped with training labels, and we mask out all the training labels from the non-surface query points (where it is not necessary to backpropagate the loss gradient of the spatial gradient using DGS). To further evaluate how the rate of known voxels affects the learning performance, we enlarge the near-surface region and evaluate when the rate is 10%, 30% and 50%. An increase in the performances among these baselines would indicate the importance of knowing more voxel labels if our proposed gradient loss (Eq. 1) is not imposed.\nii) FixedE -We train with both the near-surface as well as the spatial gradient supervision, without DGS -meaning the loss gradient of the spatial gradient would not back-propagate to any module before the sampling module -in our case, the feature encoder network. Note all the other losses without gradient sampling can still back-propagated to the feature maps. We report the ablation results in Tab. 1. Both experiments are conducted with the high-realism ShapeNet data. Once again, we comfortably outperform all the baselines, validating the essential roles of DGS in our learning framework.\nFigure: Qualitative comparisons on one challenging test case on ScannetV2. For each predicted surface with red and sky-blue colors, sky-blue indicates \"positive precision\" for that surface region, while red indicates \"negative precision\". For each ground truth surface on the top-right corner of each prediction with gold and navy-blue colors, navy-blue indicates \"positive recall\", while gold indicates \"negative recall\". The larger the blue region is, the higher F1 score would be. 4.2 LEARNING FROM REAL SCANNED DATASETS (SCANNETV2) Dataset. We use ScannetV2  for training and evaluating the performance of the models on the real images. We follow the standard training / testing split as used in and, where 1513 scenes are for trainval (with 1201 for training and 312 for validation), and 100 for testing. Each scene is provided with multiple image capture as well as the associated camera pose. We train the models with all the views given in the training / validation set (2423872 frames in total, after filtering out frames with invalid extrinsic poses), while for testing, we select 10 frames with different extrinsic poses for each test scene. Practically, since all the frames of the scenes are in the form of video clips, with adjacent frames associated with similar extrinsic cameras poses, we select the 10 frames for each frame via extracting every 100 frames from each scene video (e.g. Frame 1, 101, 201, ..., 901), resulting in 1000 frames in total in our test set (10 frames per scene, with 100 test scenes).\nMetrics. We use the same evaluation metrics following and.\nSince we are the first, to our knowledge, to evaluate single view 3D implicit reconstruction on the ScannetV2 benchmark, and here we only evaluate the geometries within the camera view frustum rather than the whole scene geometries as in;. In addition, we also only evaluate the geometries in front of the amodal depth for each pixel ray. We define the amodal depth for a pixel ray to be delineated by the minimum between the closest structure-category surface (e.g. walls and doors, etc) and the farthest surface. In practice, in order to accommodate the evaluation of the surfaces right on the amodal depth, we slack the evaluation scope with a factor λ (1.05 in our case) multiplied with the amodal depth. This evaluation protocol would be equivalent to the \"single-layered\" protocol used in, within our single-view scenario. Due to the inherent ambiguity of the scaling and shifting of the predicted 3D single view geometry, we follow them by regressing the best scale and shift comparing the predicted depth with the ground truth depth. For approaches that predict 3D surfaces, the rendered depth map from the predicted mesh would be used for calculating the scale and shift.\nBaselines. Since we demonstrate the first attempt to conduct the implicit reconstruction of singleview scenes, very few exiting works provide a direct baseline performance to our task. For Occ-Net, since its image feature extraction is not local, and its gradient propa- Figure: Two representative failure cases of our approach. gation does not require sampling, we use its direct application with Gropp et al. () \"OccNet + GeoReg\" as one baseline. We train DISN with the TSDF voxelization labels. For CoReNet, we stick to its own voxelization and internal filling toolbox for obtaining the training labels. Since CoReNet can only predict geometries within the fixed range of space, we tried our best to pick the best cube location based on the dataset statistics. We also incorporate depth approaches for comparison by finetuning their weights on ScannetV2. Lastly, we compare with the two ablation models NoGrad and FixedE as introduced in Sec. 4.1.\nResults. We provide quantitative comparison in Tab. 2 and qualitative comparison in Fig. respectively. Our model outperforms all state-of-the-art approaches as well as the ablation models. Compared to the synthetic data scenario in Tab. 3 and 1, our model demonstrates even larger advantages when compared to existing state-of-the-art approaches, as our motivation stems from addressing learning from imperfect 3D labels directly from the real scan data. Compared to single-view depth prediction approaches trained on massive data, our approach does not prevail on \"Acc\" and \"Prec\". This is due to the fact that these two metrics only project the predicted surface to the ground truth surface, giving advantages to approaches that only predict the visible surface. Our approach still prevails for other metrics (Chamfer Distance and F1), which are considered as the most important metrics. Generalization to Unseen Scenes (Pix3d and Open-Domain Images). We further test our model without further finetuning directly on unseen scenes for evaluating the generalizability of the learned model. We tried our model on Pix3d as well as test images downloaded directly from the internet. We provide a detailed qualitative comparison in Fig. and more results in Fig.. The results further indicate our learning framework exhibits promise for unseen scene generalization. Failure Cases. We provide two representative failure cases of our approach in Fig.. The first case (the first row) demonstrates difficulties in predicting the floor occupancy as a result of the noisy and non-watertight mesh during training. The second case (the second row) shows that our model cannot identify objects (e.g. chairs) and well predicts the invisible part of them.\nThis is in stark contrast to existing works.

        "evidence": "To check how PARENT correlates with human judgments when the references are elicited from humans (and less likely to be divergent), we check its correlation with the human ratings provided for the systems competing in the WebNLG challenge BIBREF6 . The task is to generate text describing 1-5 RDF triples (e.g. John E Blaha, birthPlace, San Antonio), and human ratings were collected for the outputs of 9 participating systems on 223 instances. These systems include a mix of pipelined, statistical and neural methods. Each instance has upto 3 reference texts associated with the RDF triples, which we use for evaluation.\nThe human ratings were collected on 3 distinct aspects – grammaticality, fluency and semantics, where semantics corresponds to the degree to which a generated text agrees with the meaning of the underlying RDF triples. We report the correlation of several metrics with these ratings in Table TABREF48 . Both variants of PARENT are either competitive or better than the other metrics in terms of the average correlation to all three aspects. This shows that PARENT is applicable for high quality references as well.\nWhile BLEU has the highest correlation for the grammar and fluency aspects, PARENT does best for semantics. This suggests that the inclusion of source tables into the evaluation orients the metric more towards measuring the fidelity of the content of the generation. A similar trend is seen comparing BLEU and BLEU-T. As modern neural text generation systems are typically very fluent, measuring their fidelity is of increasing importance. Between the two entailment models, PARENT-C is better due to its higher correlation with the grammaticality and fluency aspects.\nThe INLINEFORM0 parameter in the calculation of PARENT decides whether to compute recall against the table or the reference (Eq. EQREF22 ). Figure FIGREF50 shows the distribution of the values taken by INLINEFORM1 using the heuristic described in § SECREF3 for instances in both WikiBio and WebNLG. For WikiBio, the recall of the references against the table is generally low, and hence the recall of the generated text relies more on the table. For WebNLG, where the references are elicited from humans, this recall is much higher (often INLINEFORM2 ), and hence the recall of the generated text relies more on the reference.\nThe human ratings were collected on 3 distinct aspects – grammaticality, fluency and semantics, where semantics corresponds to the degree to which a generated text agrees with the meaning of the underlying RDF triples.",

        "answer": "If you want to increase your output on a Peloton ride there are definitely a few tips and tricks to follow to ensure progress. First off, I would always recommend using the same official Peloton equipment (Peloton Bike or Peloton Bike+) to ensure you are tracking consistent metrics between your rides. I would also recommend doing a Functional Threshold Power Test (FTP Test), to get a baseline of your maximum performance as well as get a power meter for each of your rides. From there, a big amount of increasing your power comes from consistency of both riding frequency as well as consistency in overloading your leg muscles during those durations. Taking Power Zone rides (PZE, PZ, PZMax) or Power Zone programs is a great way to increase your output over time. These rides/programs are tailored to your max level of effort, and as you progress over time, so will your 7 power zone levels. Besides consistently riding and keeping track of your metrics/FTP, there is a quick trick for increasing your output which is not that sustainable. The trick is to ride out of the saddle and crank the resistance all the way up (75+). If you can move your legs at 50+ cadence and over say an 80 resistance, you will be putting up over 300 output. If you can sustain that for a minute at a time and do that 3-5 times during a ride, you will easily increase your total output. Lower cadence is not ideal for increasing your power from a longevity strategy, but is a quick answer for breaking a personal record.

        "answer": "TextFooler",
        "evidence": "Datasets and Models We evaluate our adversarial attacks on different text classification datasets from tasks such as sentiment classification, subjectivity detection and question type classification. Amazon, Yelp, IMDB are sentence-level sentiment classification datasets which have been used in recent work BIBREF15 while MR BIBREF16 contains movie reviews based on sentiment polarity. MPQA BIBREF17 is a dataset for opinion polarity detection, Subj BIBREF18 for classifying a sentence as subjective or objective and TREC BIBREF19 is a dataset for question type classification.\nWe use 3 popular text classification models: word-LSTM BIBREF20, word-CNN BIBREF21 and a fine-tuned BERT BIBREF12 base-uncased classifier. For each dataset we train the model on the training data and perform the adversarial attack on the test data. For complete model details refer to Appendix.\nAs a baseline, we consider TextFooler BIBREF11 which performs synonym replacement using a fixed word embedding space BIBREF22. We only consider the top $K{=}50$ synonyms from the MLM predictions and set a threshold of 0.8 for the cosine similarity between USE based embeddings of the adversarial and input text.\nResults We perform the 4 modes of our attack and summarize the results in Table . Across datasets and models, our BAE attacks are almost always more effective than the baseline attack, achieving significant drops of 40-80% in test accuracies, with higher average semantic similarities as shown in parentheses. BAE-R+I is the strongest attack since it allows both replacement and insertion at the same token position, with just one exception. We observe a general trend that the BAE-R and BAE-I attacks often perform comparably, while the BAE-R/I and BAE-R+I attacks are much stronger. We observe that the BERT-based classifier is more robust to the BAE and TextFooler attacks than the word-LSTM and word-CNN models which can be attributed to its large size and pre-training on a large corpus.\nThe baseline attack is often stronger than the BAE-R and BAE-I attacks for the BERT based classifier. We attribute this to the shared parameter space between the BERT-MLM and the BERT classifier before fine-tuning. The predicted tokens from BERT-MLM may not drastically change the internal representations learned by the BERT classifier, hindering their ability to adversarially affect the classifier prediction.\nEffectiveness We study the effectiveness of BAE on limiting the number of R/I operations permitted on the original text. We plot the attack performance as a function of maximum $\\%$ perturbation (ratio of number of word replacements and insertions to the length of the original text) for the TREC dataset. From Figure , we clearly observe that the BAE attacks are consistently stronger than TextFooler. The classifier models are relatively robust to perturbations up to 20$\\%$, while the effectiveness saturates at 40-50$\\%$. Surprisingly, a 50$\\%$ perturbation for the TREC dataset translates to replacing or inserting just 3-4 words, due to the short text lengths.\nQualitative Examples We present adversarial examples generated by the attacks on a sentence from the IMDB and Yelp datasets in Table . BAE produces more natural looking examples than TextFooler as tokens predicted by the BERT-MLM fit well in the sentence context. TextFooler tends to replace words with complex synonyms, which can be easily detected. Moreover, BAE's additional degree of freedom to insert tokens allows for a successful attack with fewer perturbations.\nHuman Evaluation We consider successful adversarial examples generated from the Amazon and IMDB datasets and verify their sentiment and grammatical correctness. Human evaluators annotated the sentiment and the grammar (Likert scale of 1-5) of randomly shuffled adversarial examples and original texts. From Table , BAE and TextFooler have inferior accuracies compared to the Original, showing they are not always perfect. However, BAE has much better grammar scores, suggesting more natural looking adversarial examples.\nAblation Study We analyze the benefits of R/I operations in BAE in Table . From the table, the splits $\\mathbb {A}$ and $\\mathbb {B}$ are the $\\%$ of test points which compulsorily need I and R operations respectively for a successful attack. We can observe that the split $\\mathbb {A}$ is larger than $\\mathbb {B}$ thereby indicating the importance of the I operation over R. Test points in split require both R and I operations for a successful attack. Interestingly, split is largest for Subj, which is the most robust to attack (Table ) and hence needs both R/I operations. Thus, this study gives positive insights towards the importance of having the flexibility to both replace and insert words.\nRefer to the Appendix for additional results, effectiveness graphs and details of human evaluation.\nAs a baseline, we consider TextFooler (Jin et al., 2019) which performs synonym replacement using a fixed word embedding space (Mrksiˇ c et al. ´ , 2016).",

This raises challenges for learning ontologies in new domains. While a strong ontology parser is effective in small-scale corpora, an unsupervised model is beneficial for learning new entities and their relations from new data sources, and is likely to perform better on larger corpora.\nIn this paper, we focus on unsupervised terminological ontology learning and formalize a terminological ontology as a hierarchical structure of subject-verb-object triplets. We divide a terminological ontology into two components: topic hierarchies and topic relations. Topics are presented in a tree structure where each node is a topic label (noun phrase), the root node represents the most general topic, the leaf nodes represent the most specific topics, and every topic is composed of its topic label and its descendant topic labels. Topic hierarchies are preserved in topic paths, and a topic path connects a list of topics labels from the root to a leaf. Topic relations are semantic relationships between any two topics or properties used to describe one topic. Figure FIGREF1 depicts an example of a terminological ontology learned from a corpus about European cities. We extract terminological ontologies by applying unsupervised hierarchical topic modeling and relation extraction to plain text.\nTopic modeling was originally used for topic extraction and document clustering. The classical topic model, latent Dirichlet allocation (LDA) BIBREF11 , simplifies a document as a bag of its words and describes a topic as a distribution of words. Prior research BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 has shown that LDA-based approaches are adequate for (terminological) ontology learning. However, these models are deficient in that they still need human supervision to decide the number of topics, and to pick meaningful topic labels usually from a list of unigrams. Among models not using unigrams, LDA-based Global Similarity Hierarchy Learning (LDA+GSHL) BIBREF13 only extracts a subset of relations: “broader\" and “related\" relations. In addition, the topic hierarchies of KB-LDA BIBREF17 rely on hypernym-hyponym pairs capturing only a subset of hierarchies.\nConsidering the shortcomings of the existing methods, the main objectives of applying topic modeling to ontology learning are threefold.\nTo achieve the first objective, we extract noun phrases and then propose a sampling method to estimate the number of topics. For the second objective, we use language parsing and relation extraction to learn relations for the noun phrases. Regarding the third objective, we adapt and improve the hierarchical latent Dirichlet allocation (hLDA) model BIBREF19 , BIBREF20 . hLDA is not ideal for ontology learning because it builds topics from unigrams (which are not descriptive enough to serve as entities in ontologies) and the topics may contain words from multiple domains when input data have documents from many domains (see Section SECREF2 and Figure FIGREF55 ). Our model, hrLDA, overcomes these deficiencies. In particular, hrLDA represents topics with noun phrases, uses syntax and document structures such as paragraph indentations and item lists, assigns multiple topic paths for every document, and allows topic trees to grow vertically and horizontally.\nThe primary contributions of this work can be specified as follows.\nThe rest of this paper is organized into five parts. In Section 2, we provide a brief background of hLDA. In Section 3, we present our hrLDA model and the ontology generation method. In Section 4, we demonstrate empirical results regarding topic hierarchies and generated terminological ontologies. Finally, in Section 5, we present some concluding remarks and discuss avenues for future work and improvements.\nRegarding the third objective, we adapt and improve the hierarchical latent Dirichlet allocation (hLDA) model.",

        "evidence": "",
        "answer": "The degree of danger associated with any hike is subjective based on the hiker's general hiking experience, physical fitness, safety training and familiarity with the trails and terrain in the region. Many hikes are considered dangerous due to their steep pitches and exposure to the elements, while others can be considered dangerous due to less activity and poor trail blazing, such as bushwhacks. Other factors such as inclement weather can dramatically increase the danger of even a moderate hike. Proper preparedness, familiarity of the trails, understanding of incoming weather patterns and communicating your plans and timing to another person helps reduce risk in hiking the White Mountains, but one always assumes some degree of risk. A simple sprained ankle can mean life or death in bad weather, as the White Mountains, and notably the Presidential Range and Mount Washington, are notorious for life-threatening weather. Combined with very exposed routes and lack of safety equipment, even the most experienced hikers have fallen victim to the White Mountains. For experienced hikers seeking more adventurous routes, one might refer to the popular list \"The  Terrifying 25\" which provides a list of routes that have steep inclines, a lot of exposure, fun ladders and caves, among other features. Huntington Ravine on Mount Washington is considered the most dangerous in all the Whites for its erratic weather, steep, exposed trails with drop-offs, and less traveled by other hikers.",

A Black church leader and a son of early civil rights activist and minister Martin Luther King Sr., King advanced civil rights for people of color in the United States through nonviolence and civil disobedience. Inspired by his Christian beliefs and the nonviolent activism of Mahatma Gandhi, he led targeted, nonviolent resistance against Jim Crow laws and other forms of discrimination in the United States.\n\nKing participated in and led marches for the right to vote, desegregation, labor rights, and other civil rights. He oversaw the 1955 Montgomery bus boycott and later became the first president of the Southern Christian Leadership Conference (SCLC). As president of the SCLC, he led the unsuccessful Albany Movement in Albany, Georgia, and helped organize some of the nonviolent 1963 protests in Birmingham, Alabama. King was one of the leaders of the 1963 March on Washington, where he delivered his \"I Have a Dream\" speech on the steps of the Lincoln Memorial. The civil rights movement achieved pivotal legislative gains in the Civil Rights Act of 1964, Voting Rights Act of 1965, and the Fair Housing Act of 1968.\n\nThe SCLC put into practice the tactics of nonviolent protest with some success by strategically choosing the methods and places in which protests were carried out. There were several dramatic standoffs with segregationist authorities, who frequently responded violently. King was jailed several times. Federal Bureau of Investigation (FBI) director J. Edgar Hoover considered King a radical and made him an object of the FBI's COINTELPRO from 1963 forward. FBI agents investigated him for possible communist ties, spied on his personal life, and secretly recorded him. In 1964, the FBI mailed King a threatening anonymous letter, which he interpreted as an attempt to make him commit suicide.\n\nOn October 14, 1964, King won the Nobel Peace Prize for combating racial inequality through nonviolent resistance. In 1965, he helped organize two of the three Selma to Montgomery marches. In his final years, he expanded his focus to include opposition towards poverty, capitalism, and the Vietnam War. In 1968, King was planning a national occupation of Washington, D.C., to be called the Poor People's Campaign, when he was assassinated on April 4 in Memphis, Tennessee. His death was followed by national mourning, as well as anger leading to riots in many U.S. cities. King was posthumously awarded the Presidential Medal of Freedom in 1977 and the Congressional Gold Medal in 2003. Martin Luther King Jr. Day was established as a holiday in cities and states throughout the United States beginning in 1971; the federal holiday was first observed in 1986.

        "evidence": "The son of Checochinican (Chickoconecon), chief of the Fish Clan of the Turtle tribe, Nemacolin was born near the Brandywine Creek, probably close to the Swedish trading post at Fort Christina that later became Wilmington, Delaware. By a treaty with William Penn in 1726, various tribes either rented or gave up their land on both sides of Brandywine Creek. Nemacolin likely grew up near Shamokin, Pennsylvania, a village near the Susquehanna River to which the Delaware had retreated when faced with disease and colonization of their traditional lands by white settlers. His family grew to know trader Thomas Cresap, and moved south and west with the Cresap family, likely after a controversy between groups of settlers aligned with the colonies of Maryland and Pennsylvania known as Cresap's War.\n\nCirca 1750, Cresap received instructions to improve the Native American path across the Appalachian Mountains through the Cumberland Narrows. He hired Nemacolin and his two sons, among others, to complete the task between Will's Creek (a trading post on a tributary of the Potomac River later the site of Fort Cumberland) and the mouth of Redstone Creek on the Monongahela River (a tributary of the Ohio River) which later became Redstone Old Fort and even later Brownsville, Pennsylvania. A side trail led to the residence of Christopher Gist. Gist led George Washington along Nemacolin's Path in 1753 and 1754. It was later improved to permit supply wagons for General Edward Braddock's army, and the General ultimately died on the route in 1755 after the disastrous Battle of the Monongahela near present day Pittsburgh. About 1759, as the war ended, Nemocolin reblazed the path to the residence of James Burd which became Fort Burd and later renamed Redstone Old Fort. Another branch went to Uniontown, Pennsylvania.",

I pushed through people to get closer and assure myself I wasn’t imagining any noise. The closer I walked the louder the noise got.\n                    I wanted to do something. They could have been alive! More and more people finish saying their goodbyes. Soon they would lower the coffin.

I start running with my head down, I don’t want to see everyone's reactions. It’s so hard to see in the dark but I just keep on running. I trip over a stick that was laying in the middle of the path.

        "answer": "The authors propose a novel approach to learning binary codes for text documents.",
        "evidence": "One of the significant challenges in contemporary information processing is the sheer volume of available data. BIBREF0 , for example, claim that the amount of digital data in the world doubles every two years. This trend underpins efforts to develop algorithms that can efficiently search for relevant information in huge datasets. One class of such algorithms, represented by, e.g., Locality Sensitive Hashing BIBREF1 , relies on hashing data into short, locality-preserving binary codes BIBREF2 . The codes can then be used to group the data into buckets, thereby enabling sublinear search for relevant information, or for fast comparison of data items. Most of the algorithms from this family are data-oblivious, i.e. can generate hashes for any type of data. Nevertheless, some methods target specific kind of input data, like text or image.\nIn this work we focus on learning binary codes for text documents. An important work in this direction has been presented by BIBREF3 . Their semantic hashing leverages autoencoders with sigmoid bottleneck layer to learn binary codes from a word-count bag-of-words (BOW) representation. Salakhutdinov & Hinton report that binary codes allow for up to 20-fold improvement in document ranking speed, compared to real-valued representation of the same dimensionality. Moreover, they demonstrate that semantic hashing codes used as an initial document filter can improve precision of TF-IDF-based retrieval. Learning binary representation from BOW, however, has its disadvantages. First, word-count representation, and in turn the learned codes, are not in itself stronger than TF-IDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such high-dimensional vectors is impractical. Salakhutdinov & Hinton restricted the BOW vocabulary in their experiments to 2000 most frequent words.\nBinary codes have also been applied to cross-modal retrieval where text is one of the modalities. Specifically, BIBREF4 incorporated tag information that often accompany text documents, while BIBREF5 employed siamese neural networks to learn single binary representation for text and image data.\nRecently several works explored simple neural models for unsupervised learning of distributed representations of words, sentences and documents. BIBREF6 proposed log-linear models that learn distributed representations of words by predicting a central word from its context (CBOW model) or by predicting context words given the central word (Skip-gram model). The CBOW model was then extended by BIBREF7 to learn distributed representations of documents. Specifically, they proposed Paragraph Vector Distributed Memory (PV-DM) model, in which the central word is predicted given the context words and the document vector. During training, PV-DM learns the word embeddings and the parameters of the softmax that models the conditional probability distribution for the central words. During inference, word embeddings and softmax weights are fixed, but the gradients are backpropagated to the inferred document vector. In addition to PV-DM, Le & Mikolov studied also a simpler model, namely Paragraph Vector Distributed Bag of Words (PV-DBOW). This model predicts words in the document given only the document vector. It therefore disregards context surrounding the predicted word and does not learn word embeddings. Le & Mikolov demonstrated that paragraph vectors outperform BOW and bag-of-bigrams in information retrieval task, while using only few hundreds of dimensions. These models are also amendable to learning and inference over large vocabularies. Original CBOW network used hierarchical softmax to model the probability distribution for the central word. One can also use noise-contrastive estimation BIBREF8 or importance sampling BIBREF9 to approximate the gradients with respect to the softmax logits.\nAn alternative approach to learning representation of pieces of text has been recently described by BIBREF10 . Networks proposed therein, inspired by the Skip-gram model, learn to predict surrounding sentences given the center sentence. To this end, the center sentence is encoded by an encoder network and the surrounding sentences are predicted by a decoder network conditioned on the center sentence code. Once trained, these models can encode sentences without resorting to backpropagation inference. However, they learn representations at the sentence level but not at the document level.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PV-DM that learn short binary codes for text documents. One inspiration for binary paragraph vectors comes from a recent work by BIBREF11 on learning binary codes for images. Specifically, we introduce a sigmoid layer to the paragraph vector models, and train it in a way that encourages binary activations. We demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes. We also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora. Finally, we study models that simultaneously learn short binary codes for document filtering and longer, real-valued representations for ranking. While BIBREF11 employed a supervised criterion to learn image codes, binary paragraph vectors remain unsupervised models: they learn to predict words in documents.\nIn this work we focus on learning binary codes for text documents.",

        "question": "Can the dependency tree-based model predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76)?",
        "answer": "Yes, it can.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nOur experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76).",

It took several years for the business to take hold, and as it gained popularity, MarCal's moved to a larger location in Chilton that also had space for events.  Marty would later partner with his brother, Ed, to start MarCal's Too in Valders, WI. When his son, Dave, finished culinary training, Dave partnered with his sister Nancy to run the Chilton location.  Marty and Margie moved to start another MarCal's diner in the city of Brillion, WI.  The business thrived for many years, with Marty leading operations and being the primary cook, and Margie working as a waitress and running the front of the business, as well as the accounting. Sunday morning breakfasts were always busy, and one item on the menu Marty was particularly proud of was the potato pancakes.  The recipe for these pancakes came from Marty's mother, Eva Salm, who knew a thing or two about feeding a large number of people since she had to keep her family of 15 children fed, as well as their many farm hands.  MarCals restaurants no longer exist, as they were all closed at various times after Marty and Margie's retirement, but many a fond memory of Sunday breakfasts and lunch time buffets still remain.",

It is the oldest organized sport in North America,[ with its origins with the indigenous people of North America as early as the 12th century.The game was extensively modified by European colonists, reducing the violence, to create its current collegiate and professional form.\n\nPlayers use the head of the lacrosse stick to carry, pass, catch, and shoot the ball into the goal. The sport has four versions that have different sticks, fields, rules and equipment: field lacrosse, women's lacrosse, box lacrosse and intercrosse. The men's games, field lacrosse (outdoor) and box lacrosse (indoor), are contact sports and all players wear protective gear: helmet, gloves, shoulder pads, and elbow pads. The women's game is played outdoors and does not allow body contact but does allow stick to stick contact.The only protective gear required for women players is eyegear, while goalies wear helmets and protective pads. Both men's and women's field lacrosse have 6v6 versions played on smaller fields, gaining acceptance in multi-sport events. Intercrosse is a mixed-gender non-contact sport played indoors that uses an all-plastic stick and a softer ball.\n\nThe modern sport is governed by World Lacrosse and is the only international sport organization to recognize First Nations bands and Native American tribes as sovereign nations.The organization hosts the World Lacrosse Championship for men, the Women's Lacrosse World Cup, the World Indoor Lacrosse Championship for box lacrosse, and the Under-19 World Lacrosse Championships for both men and women.

To evaluate the news suggestion problem we are faced with two challenges.\nWhat comprises the ground truth for such a task ?\nHow do we construct training and test splits given that entity pages consists of text added at different points in time ?\nConsider the ground truth challenge. Evaluating if an arbitrary news article should be included in Wikipedia is both subjective and difficult for a human if she is not an expert. An invasive approach, which was proposed by Barzilay and Sauper BIBREF8 , adds content directly to Wikipedia and expects the editors or other users to redact irrelevant content over a period of time. The limitations of such an evaluation technique is that content added to long-tail entities might not be evaluated by informed users or editors in the experiment time frame. It is hard to estimate how much time the added content should be left on the entity page. A more non-invasive approach could involve crowdsourcing of entity and news article pairs in an IR style relevance assessment setup. The problem of such an approach is again finding knowledgeable users or experts for long-tail entities. Thus the notion of relevance of a news recommendation is challenging to evaluate in a crowd setup.\nWe take a slightly different approach by making an assumption that the news articles already present in Wikipedia entity pages are relevant. To this extent, we extract a dataset comprising of all news articles referenced in entity pages (details in Section SECREF40 ). At the expense of not evaluating the space comprising of news articles absent in Wikipedia, we succeed in (i) avoiding restrictive assumptions about the quality of human judgments, (ii) being invasive and polluting Wikipedia, and (iii) deriving a reusable test bed for quicker experimentation.\nThe second challenge of construction of training and test set separation is slightly easier and is addressed in Section SECREF46 .\nTo evaluate the news suggestion problem we are faced with two challenges. • What comprises the ground truth for such a task ? • How do we construct training and test splits given that entity pages consists of text added at different points in time ?",

        "evidence": "We extended the notion of consistency of a recurrent language model put forward by BIBREF16 to incorporate a decoding algorithm, and used it to analyze the discrepancy between a model and the distribution induced by a decoding algorithm. We proved that incomplete decoding is inconsistent, and proposed two methods to prevent this: consistent decoding and the self-terminating recurrent language model. Using a sequence completion task, we confirmed that empirical inconsistency occurs in practice, and that each method prevents inconsistency while maintaining the quality of generated sequences. We suspect the absence of decoding in maximum likelihood estimation as a cause behind this inconsistency, and suggest investigating sequence-level learning as an alternative in the future.\nInconsistency may arise from the lack of decoding in solving this optimization problem. Maximum likelihood learning fits the model $p_{\\theta }$ using the data distribution, whereas a decoded sequence from the trained model follows the distribution $q_{\\mathcal {F}}$ induced by a decoding algorithm. Based on this discrepancy, we make a strong conjecture: we cannot be guaranteed to obtain a good consistent sequence generator using maximum likelihood learning and greedy decoding. Sequence-level learning, however, uses a decoding algorithm during training BIBREF25, BIBREF26.

        "answer": "The models and learning methods for multimodal intelligence.",
        "evidence": "Significant progress has been made in the field of machine learning in the past years due to the rapid development of deep learning BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5. Dating back to the dramatic increase in the accuracy of large-scale automatic speech recognition (ASR) using fully connected deep neural networks (DNN) and deep auto-encoders around 2010 BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, and followed by a set of breakthroughs in computer vision (CV) using deep convolutional neural network (CNN) models BIBREF17 for large-scale image classification around 2012 BIBREF18, BIBREF19, BIBREF20, BIBREF21 and large-scale object detection BIBREF22, BIBREF23, BIBREF24 around 2014, a set of major milestones have been achieved in pattern recognition with single input modality. Subsequently, in natural language processing (NLP), recurrent neural network (RNN) based semantic slot filling methods BIBREF25 achieved new state-of-the-art in spoken language understanding, and RNN-encoder-decoder models with attention mechanism BIBREF26, also referred to as sequence to sequence models BIBREF27, produced superior performance in machine translation in an end-to-end fashion BIBREF28, BIBREF29. For other NLP tasks without much training data, such as question answering (QA) and machine reading comprehension, generative pre-training that transfers parameters from a language model (LM) pre-trained on a large out-of-domain data set using unsupervised or self learning then followed by fine-tuning on small in-domain data sets, achieved record-breaking results over a set of tasks BIBREF30, BIBREF31, BIBREF32.\nDespite the advances in vision, speech, and language processing, many problems in artificial intelligence involve more than one modality, such as an intelligent personal assistant (IPA) that should understand human communicative intentions embedded not only in spoken language, but also in body and pictorial languages BIBREF33. Therefore, it is of broad interests to study the modeling and learning approaches across multiple modalities BIBREF34. Benefiting from the advances in image processing and language understanding BIBREF35, a set of tasks that combine both image and text have drawn much attention, which include visual grounding tasks like referring expression understanding and phrase localization BIBREF36, BIBREF37, BIBREF38, image captioning BIBREF39, BIBREF40, BIBREF41, visual QA (VQA) BIBREF42, BIBREF43, BIBREF44, text-to-image generation BIBREF45, BIBREF46, BIBREF47, and visual-language navigation BIBREF48 etc. In these tasks, natural language plays a key role in helping the machine to “understand” the content of the images, where “understand” means to capture the underlying correlations between the semantics embedded in language with the visual features obtained from the images. In addition to text, vision can be combined with speech as well. Such tasks include audio-visual speech recognition BIBREF49, BIBREF50, BIBREF51, speaker recognition BIBREF52, BIBREF53, BIBREF54, as well as speech diarisation BIBREF55, BIBREF56, separation BIBREF57, BIBREF58 and enhancement BIBREF59, which mostly focused on the use of visual features to improve the robustness of the audio-only methods.\nIn this paper, a technical review of the models and learning methods for multimodal intelligence is provided. The main focus is the combination of CV and NLP, which has become an important area for both research communities covering many different tasks and technologies. To provide a more structured perspective, we organize the methods selected in this technical review according to three key topics: representation, fusion, and applications.\nLearning representations for the input data is a core problem for deep learning. For multimodal tasks, collecting paralleled data across all modalities can be quite difficult and leveraging pre-trained representations with desired properties, such as suitable for zero-shot or few-shot learning, is often an effective solution to the issue. Both supervised and unsupervised training based multimodal representation learning methods are reviewed.\nThe fusion of the features or representations of the single modalities is undoubtedly a centric problem of any multimodal task. Different from previous studies that often categorise the related work into early, middle and late stage methods based on the stage that fusion happens in the procedure, we classify them according to the actual operation used in the fusion, such as attention and bilinear pooling, since it becomes difficult to classify some recent complex approaches into stages.\nThree types of applications are reviewed in this paper, namely image captioning, text-to-image synthesis and VQA. This is to give an idea how representation learning and fusion can be applied to specific tasks, and to provide a viewpoint of the situation of the current development of the multimodal applications, especially those integrating vision with natural languages. Visual reasoning methods for VQA are also discussed in the end.\nThis paper is organised as follows. Section SECREF2 reviews the recent progress on developing representations for single or multiple modalities. Section SECREF3 introduces the commonly used fusion methods, particularly attention and bilinear pooling. Applications including caption generation, text-to-image synthesis, VQA, and visual reasoning are introduced in Section SECREF4, followed by conclusions.\nIn this paper, a technical review of the models and learning methods for multimodal intelligence is provided.

For daily use in a typical salt shaker, iodized table salt is the most common as it is processed to be free-flowing and fits through most salt shaker lids with ease.  For brining and during the cooking process most chefs and cooks will choose to only use kosher salt due to it’s flake size and consistency across recipes but they will typically choose one particular brand and stick with it.  For finishing a dish with salt, chefs will also choose a large crystal sea salt usually pyramid shaped as it delivers a satisfying crunch and flavor to the final dish.

A tweet is annotated with one of three classes that indicate the framing of the tweet with respect to responsibility for the plane crash.

Example tweets for each category can be found in Table TABREF9. These examples illustrate that the framing annotations do not reflect general polarity, but polarity with respect to responsibility to the crash. For example, even though the last example in the table is in general pro-Ukrainian, as it displays the separatists in a bad light, the tweet does not focus on responsibility for the crash.

        "question": "What can be generated by their zero-shot customization technique through verification?",
        "answer": "Need-specific summaries.",
        "evidence": "The proliferation of opinions expressed in online reviews, blogs, internet forums, and social media has created a pressing need for automated systems which enable customers, companies, or service providers to make informed decisions without having to absorb large amounts of opinionated text. Opinion summarization is the task of automatically generating summaries for a set of opinions about a specific target BIBREF0. Figure FIGREF1 shows various reviews about the movie “Coach Carter” and example summaries generated by humans and automatic systems. The vast majority of previous work BIBREF1 views opinion summarization as the final stage of a three-step process involving: (1) aspect extraction (i.e., finding features pertaining to the target of interest, such as battery life or sound quality); (2) sentiment prediction (i.e., determining the sentiment of the extracted aspects); and (3) summary generation (i.e., presenting the identified opinions to the user). Textual summaries are created following mostly extractive methods which select representative segments (usually sentences) from the source text BIBREF2, BIBREF3, BIBREF4, BIBREF5. Despite being less popular, abstractive approaches seem more appropriate for the task at hand as they attempt to generate summaries which are maximally informative and minimally redundant without simply rearranging passages from the original opinions BIBREF6, BIBREF7, BIBREF8, BIBREF9. General-purpose summarization approaches have recently shown promising results with end-to-end models which are data-driven and take advantage of the success of sequence-to-sequence neural network architectures. Most approaches BIBREF10, BIBREF11, BIBREF12, BIBREF13 encode documents and then decode the learned representations into an abstractive summary, often by attending to the source input BIBREF14 and copying words from it BIBREF15. Under this modeling paradigm, it is no longer necessary to identify aspects and their sentiment for the opinion summarization task, as these are learned indirectly from training data (i.e., sets of opinions and their corresponding summaries). These models are usually tested on domains where the input is either one document or a small set of documents. However, the number of opinions tends to be very large (150 for the example in Figure FIGREF1). It is therefore practically unfeasible to train a model in an end-to-end fashion, given the memory limitations of modern hardware. As a result, current approaches BIBREF16, BIBREF17, BIBREF18, BIBREF19 sacrifice end-to-end elegance in favor of a two-stage framework which we call Extract-Abstract: an extractive model first selects a subset of opinions and an abstractive model then generates the summary while conditioning on the extracted subset (see Figure FIGREF5). The extractive pass unfortunately has two drawbacks. Firstly, on account of having access to a subset of opinions, the summaries can be less informative and inaccurate, as shown in Figure FIGREF1. And secondly, user preferences cannot be easily taken into account (e.g., the reader may wish to obtain a summary focusing on the acting or plot of a movie as opposed to a general-purpose summary) since more specialized information might have been removed.\nIn this paper, we propose Condense-Abstract, an alternative two-stage framework which uses all input documents when generating the summary (see Figure FIGREF5). We view the opinion summarization problem as an instance of multi-source transduction BIBREF20; we first represent the input documents as multiple encodings, aiming to condense their meaning and distill information relating to sentiment and various aspects of the target being reviewed. These condensed representations are then aggregated using a multi-source fusion module based on which an opinion summary is generated using an abstractive model. We also introduce a zero-shot customization technique allowing users to control important aspects of the generated summary at test time. Our approach enables controllable generation while leveraging the full spectrum of opinions available for a specific target. We perform experiments on a dataset consisting of movie reviews and opinion summaries elicited from the Rotten Tomatoes website (BIBREF16; see Figure FIGREF1). Our framework outperforms state-of-the-art models by a large margin using automatic metrics and in a judgment elicitation study. We also verify that our zero-shot customization technique can effectively generate need-specific summaries.\nWe also verify that our zero-shot customization technique can effectively generate need-specific summaries.",

The goal of our crowdsourcing scheme is to obtain a score for each proposition indicating its importance in a document cluster, such that a ranking according to the score would reveal what is most important and should be included in a summary. In contrast to other work, we do not show the documents to the workers at all, but provide only a description of the document cluster's topic along with the propositions. This ensures that tasks are small, simple and can be done quickly (see Figure FIGREF4 ).\nIn preliminary tests, we found that this design, despite the minimal context, works reasonably on our focused clusters on common educational topics. For instance, consider Figure FIGREF4 : One can easily say that P1 is more important than P2 without reading the documents.\nWe distinguish two task variants:\nInstead of enforcing binary importance decisions, we use a 5-point Likert-scale to allow more fine-grained annotations. The obtained labels are translated into scores (5..1) and the average of all scores for a proposition is used as an estimate for its importance. This follows the idea that while single workers might find the task subjective, the consensus of multiple workers, represented in the average score, tends to be less subjective due to the “wisdom of the crowd”. We randomly group five propositions into a task.\nAs an alternative, we use a second task design based on pairwise comparisons. Comparisons are known to be easier to make and more consistent BIBREF32 , but also more expensive, as the number of pairs grows quadratically with the number of objects. To reduce the cost, we group five propositions into a task and ask workers to order them by importance per drag-and-drop. From the results, we derive pairwise comparisons and use TrueSkill BIBREF35 , a powerful Bayesian rank induction model BIBREF34 , to obtain importance estimates for each proposition.\nWe break down the task of importance annotation to the level of single propositions.

        "question": "Do UIT-ViIC models perform better than the sportball dataset translated automatically?",
        "answer": "Yes, but differs between datasets.",
        "evidence": "The two following tables, Table TABREF36 and Table TABREF36, summarize experimental results of Pytorch-tutorial, NIC - Show and Tell models. The two models are trained with three mentioned datasets, which are English-sportball, GT-sportball, UIT-ViIC. After training, 924 images from validation subset for each dataset are used to validate the our models.\nAs can be seen in Table TABREF36, with model from Pytorch tutorial, MS-COCO English captions categorized with sportball yields better results than the two Vietnamese datasets. However, as number of consecutive words considered (BLEU gram) increase, UIT-ViIC’s BLEU scores start to pass that of English sportball and their gaps keep growing. The ROUGE-L and CIDEr-D scores for UIT-ViIC model prove the same thing, and interestingly, we can observe that the CIDEr-D score for the UIT-ViIC model surpasses English-sportball counterpart.\nThe same conclusion can be said from Table TABREF36. Show and Tell model’s results show that MS-COCO sportball English captions only gives better result at BLEU-1. From BLEU-3 to BLEU-4, both GT-sportball and UIT-ViIC yield superior scores to English-sportball. Besides, when limiting MS-COCO English dataset to sportball category only, the results are higher (0.689, 0.501, 0.355, 0.252) than when the model is trained on MS-COCO with all images, which scored only 0.629, 0.436, 0.290, 0.193 (results without tuning in 2018) from BLEU-1 to BLEU-4 respectively.\nWhen we compare between two Vietnamese datasets, UIT-ViIC models perform better than sportball dataset translated automatically, GT-sportball. The gaps between the two results sets are more trivial in NIC model, and the numbers get smaller as the BLEU’s n-gram increase.\nIn Fig. FIGREF37, two images inputted into the models generate two Vietnamese captions that are able to describe accurately the sport game, which is soccer. The two models can also differentiate if there is more than one person in the images. However, when comparing GT-sportball outputs with UIT-ViIC ones in both images, UIT-ViIC yield captions that sound more naturally, considering Vietnamese language. Furthermore, UIT-ViIC demonstrates the specific action of the sport more accurately than GT-sportball. For example, in the below image of Fig. FIGREF37, UIT-ViIC tells the exact action (the man is preparing to throw the ball), whereas GT-sportball is mistaken (the man swing the bat). The confusion of GT-sportball happens due to GT-sportball train set is translated from original MS-COCO dataset, which is annotated in more various perspective and wider vocabulary range with the dataset size is not big enough.\nThere are cases when the main objects are too small, both English and GT - sportball captions tell the unexpected sport, which is tennis instead of baseball, for instance. Nevertheless, the majority of UIT-ViIC captions can tell the correct type of sport and action, even though the gender and age identifications still need to be improved.\nWhen we compare between two Vietnamese datasets, UIT-ViIC models perform better than sportball dataset translated automatically, GT-sportball. The gaps between the two results sets are more trivial in NIC model, and the numbers get smaller as the BLEU’s n-gram increase.",

Antonio Meucci, Alexander Graham Bell, and Elisha Gray amongst others, have all been credited with the telephone's invention. The early history of the telephone became and still remains a confusing morass of claims and counterclaims, which were not clarified by the huge number of lawsuits filed in order to resolve the patent claims of the many individuals and commercial competitors. The Bell and Edison patents, however, were commercially decisive, because they dominated telephone technology and were upheld by court decisions in the United States.\n\nThe modern telephone is the result of the work of many people. Alexander Graham Bell was, however, the first to patent the telephone, as an \"apparatus for transmitting vocal or other sounds telegraphically\". Bell has most often been credited as the inventor of the first practical telephone. Johann Philipp Reis coined the term \"telephon\". Models of it were sent abroad, to London, Dublin, Tiflis, and other places. It became a subject for popular lectures, and an article for scientific cabinets. Edison credited him as the \"first inventor of the telephone.\" The Italian-American inventor and businessman Antonio Meucci has been recognized by the U.S. House of Representatives for his contributory work on the telephone. Several other controversies also surround the question of priority of invention for the telephone.\nThe Elisha Gray and Alexander Bell telephone controversy considers the question of whether Bell and Gray invented the telephone independently and, if not, whether Bell stole the invention from Gray. This controversy is narrower than the broader question of who deserves credit for inventing the telephone, for which there are several claimants.",

        "question": "Do the attribute representations transfer well to other tasks?",
        "answer": "Yes, they do.",
        "evidence": "The use of categorical attributes (e.g., user, topic, aspects) in the sentiment analysis community BIBREF0, BIBREF1, BIBREF2 is widespread. Prior to the deep learning era, these information were used as effective categorical features BIBREF3, BIBREF4, BIBREF5, BIBREF6 for the machine learning model. Recent work has used them to improve the overall performance BIBREF7, BIBREF8, interpretability BIBREF9, BIBREF10, and personalization BIBREF11 of neural network models in different tasks such as sentiment classification BIBREF12, review summarization BIBREF13, and text generation BIBREF8.\nIn particular, user and product information have been widely incorporated in sentiment classification models, especially since they are important metadata attributes found in review websites. BIBREF12 first showed significant accuracy increase of neural models when these information are used. Currently, the accepted standard method is to use them as additional biases when computing the weights $a$ in the attention mechanism, as introduced by BIBREF7 as:\nwhere $u$ and $p$ are the user and product embeddings, and $h$ is a word encoding from BiLSTM. Since then, most of the subsequent work attempted to improve the model by extending the model architecture to be able to utilize external features BIBREF14, handle cold-start entities BIBREF9, and represent user and product separately BIBREF15.\nIntuitively, however, this method is not the ideal method to represent and inject attributes because of two reasons. First, representing attributes as additional biases cannot model the relationship between the text and attributes. Rather, it only adds a user- and product-specific biases that are independent from the text when calculating the attention weights. Second, injecting the attributes in the attention mechanism means that user and product information are only used to customize how the model choose which words to focus on, as also shown empirically in previous work BIBREF7, BIBREF15. However, we argue that there are more intuitive locations to inject the attributes such as when contextualizing words to modify their sentiment intensity.\nWe propose to represent user and product information as weight matrices (i.e., $W$ in the equation above). Directly incorporating these attributes into $W$ leads to large increase in parameters and subsequently makes the model difficult to optimize. To mitigate these problems, we introduce chunk-wise importance weight matrices, which (1) uses a weight matrix smaller than $W$ by a chunk size factor, and (2) transforms these matrix into gates such that it corresponds to the relative importance of each neuron in $W$. We investigate the use of this method when injected to several locations in the base model: word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.\nThe results of our experiments can be summarized in three statements. First, our preliminary experiments show that doing bias-based attribute representation and attention-based injection is not an effective method to incorporate user and product information in sentiment classification models. Second, despite using only a simple BiLSTM with attention classifier, we significantly outperform previous state-of-the-art models that use more complicated architectures (e.g., models that use hierarchical models, external memory networks, etc.). Finally, we show that these attribute representations transfer well to other tasks such as product category classification and review headline generation.\nFinally, we show that these attribute representations transfer well to other tasks such as product category classification and review headline generation.",

Many transport organizations rely on complaints gathered via these platforms to improve their services, hence understanding these are important for: (1) linguists to identify human expressions of criticism and (2) organizations to improve their query response time and address concerns effectively.\nPresence of inevitable noise, sparse content along with rephrased and structurally morphed instances of posts, make the task at hand difficult BIBREF1.

For many skiers their first memories of skiing are as a kid with their parents, and brings forward fond childhood memories of snow days, hot chocolate and being outdoors.  But what makes skiing so wonderful is that is blends both individual pursuits and as a group activity.  It is a fun activity to do with a group where all the participants are experiencing the outdoors and the trails together.  At the same time, each skier is dependent on their own skills to get down the trail, thereby providing the individual to have their own challenges and experience while spending time with friends or family.  \n\nSkiing offers the opportunity to enjoy the natural wonders of the mountains and experience breathtaking views.  Every day brings different conditions the skier has to adjust to; visibility, temperature, snow conditions.  These all factor into how the skier is going to ski the terrain, which in-turn provides variety to skiing, even if you are visiting the same mountain and skiing the same trails.  \n\nSkiing is known for having a communal type of culture.  Getting on a chair lift with a stranger can often times lead to great conversations, all be it short ones, the chair lift can be a time to connect with other skiers to learn what trails are offering the best conditions, or what areas of the mountain to avoid.  Skiers often look out for one another on the slopes to ensure others are safe if someone falls.\n\nThe exhilaration of speeding down snow packed trail, with views of the mountains and valleys around you, or through the quite of snow capped trees, enjoying time with friends or family, makes skiing one of the best sports people of all ages can enjoy; from little kids to people in their 60's, 70's and even 80's can still enjoy.",

Results are shown in Table TABREF20 . Surprisingly, the MBN features perform relatively poorly compared to the standard MFCC. These results are contradictory to those reported in BIBREF3 . Two factors may explain this discrepancy: the Mboshi5k data being different from the training data of the MBN neural network, the neural network may not generalize well. Another possibility may be that the initialization scheme of the model is not suitable for this type of features. Indeed, Variational Bayesian Inference algorithm converges only to a local optimum of the objective function and is therefore dependent of the initialization. We believe the second explanation is the more likely since, as we shall see shortly, the best results in term of word segmentation and NMI are eventually obtained with the MBN features when the inference is done with the informative prior. Next, we compared the HMM and the SVAE models when trained with an uninformative prior (lines with \"Inf. Prior\" set to \"no\" in Table TABREF23 ). The SVAE significantly improves the NMI and the precision showing that it extracts more consistent units than the HMM model. However, it also degrades the segmentation in terms of recall. We further investigated this behavior by looking at the duration of the units found by both models compared to the true phones (Table TABREF22 ). We observe that the SVAE model favors longer units than the HMM model hence leading to fewer boundaries and consequently smaller recall.\nWe then evaluated the effect of the informative prior on the acoustic unit discovery (Table TABREF23 ). On all 4 combinations (2 features sets INLINEFORM0 2 models) we observe an improvement in terms of precision and NMI but a degradation of the recall. This result is encouraging since the informative prior was trained on English data (TIMIT) which is very different from Mboshi. Indeed, this suggests that even speech from an unrelated language can be of some help in the design of an ASR for a very low resource language. Finally, similarly to the SVAE/HMM case described above, we found that the degradation of the recall is due to longer units discovered for models with an informative prior (numbers omitted due to lack of space).\nWord discovery results are given in Table TABREF21 for the Boundary metric BIBREF20 , BIBREF21 . We observe that i) the best word boundary detection (F-score) is obtained with MBN features, an informative prior and the SVAE model; this confirms the results of table TABREF23 and shows that better AUD leads to better word segmentation ii) word segmentation from AUD graph Lattices is slightly better than from flat sequences of AUD symbols (1-best); iii) our results outperform a pure speech based baseline based on segmental DTW BIBREF22 (F-score of 19.3% on the exact same corpus).\nFirst, we evaluated the standard HMM model with an uninformative prior (this will be our baseline) for the two different input features: MFCC (and derivatives) and MBN.",

        "evidence": "The preconditioning for the financial crisis were complex and multi-causal. Almost two decades prior, the U.S. Congress had passed legislation encouraging financing for affordable housing. However, in 1999, parts of the Glass-Steagall legislation, which had been adopted in 1933, were repealed, permitting financial institutions to commingle their commercial (risk-averse) and proprietary trading (risk-taking) operations. Arguably the largest contributor to the conditions necessary for financial collapse was the rapid development in predatory financial products which targeted low-income, low-information homebuyers who largely belonged to racial minorities. This market development went unattended by regulators and thus caught the U.S. government by surprise.",
        "answer": "There were multiple factors that caused the financial crises.  Two decades before the crisis, the U.S Government implemented multiple new laws to help encourage financing for affordable housing.  However, in 1999, portions of the Glass-Steagall act, which was passed by congress in 1933, was repealed and as a result, created more overall risk in the financial system as it allowed institutions to commingle low risk real estate investments with riskier investment operations.  The final major factor was a large increase in predatory home loan lending practices which targeted low-income, low-credit, uninformed homebuyers (mostly racial minorities).  The severity of these factors went unnoticed by U.S financial regulators and by the time the effects surfaced, the government was caught by surprise.",

        "answer": "In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation.",
        "evidence": "The pre-trained language model, BERT BIBREF0 has led to a big breakthrough in various kinds of natural language understanding tasks. Ideally, people can start from a pre-trained BERT checkpoint and fine-tune it on a specific downstream task. However, the original BERT models are memory-exhaustive and latency-prohibitive to be served in embedded devices or CPU-based online environments. As the memory and latency constraints vary in different scenarios, the pre-trained BERT model should be adaptive to different requirements with accuracy retained to the largest extent. Existing BERT-oriented model compression solutions largely depend on knowledge distillation BIBREF1, which is inefficient and resource-consuming because a large training corpus is required to learn the behaviors of a teacher. For example, DistilBERT BIBREF2 is re-trained on the same corpus as pre-training a vanilla BERT from scratch; and TinyBERT BIBREF3 utilizes expensive data augmentation to fit the distillation target. The costs of these model compression methods are as large as pre-training and unaffordable for low-resource settings. Therefore, it is straight-forward to ask, can we design a lightweight method to generate adaptive models with comparable accuracy using significantly less time and resource consumption? In this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions. Specifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation. Initially, the architecture and weights of student model are inherited from the BERT teacher. In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation. Because weight pruning and matrix factorization help to generate better initial and intermediate status\nin the knowledge distillation iterations, the accuracy and efficiency of model compression can be greatly improved.\nWe conduct extensive experiments on five public datasets of natural language understanding. As an example, the performance comparison of LadaBERT and state-of-the-art models on MNLI-m dataset is illustrated in Figure FIGREF1. We can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios. Especially, LadaBERT-1 outperforms BERT-PKD significantly under $2.5\\times $ compression ratio, and LadaBERT-3 outperforms TinyBERT under $7.5\\times $ compression ratio while the training speed is accelerated by an order of magnitude.\nThe rest of this paper is organized as follows. First, we summarizes the related works of model compression and their applications to BERT in Section SECREF2. Then, the methodology of LadaBERT is introduced in Section SECREF3, and experimental results are presented in Section SECREF4. At last, we conclude this work and discuss future works in Section SECREF5.\nIn each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation.",

Even though low-resource settings have also been explored, this progress has overwhelmingly been observed in languages with significant data resources that can be leveraged to train deep neural networks. Low-resource languages still lag behind.\nEndangered languages pose an additional challenge. The process of documenting an endangered language typically includes the creation of word lists, audio and video recordings, notes, or grammar fragments, with the created resources then stored in large online linguistics archives. This process is often hindered by the Transcription Bottleneck: the linguistic fieldworker and the language community may not have time to transcribe all of the recordings and may only transcribe segments that are linguistically salient for publication or culturally significant for the creation of community resources.\nWith this work we make publicly available a large corpus in Mapudungun, a language of the indigenous Mapuche people of southern Chile and western Argentina. We hope to ameliorate the resource gap and the transcription bottleneck in two ways. First, we are providing a larger data set than has previously been available, and second, we are providing baselines for NLP tasks (speech recognition, speech synthesis, and machine translation). In providing baselines and datasets splits, we hope to further facilitate research on low-resource NLP for this language through our data set. Research on low-resource speech recognition is particularly important in relieving the transcription bottleneck, while tackling the research challenges that speech synthesis and machine translation pose for such languages could lead to such systems being deployed to serve more under-represented communities.\nFirst, we are providing a larger data set than has previously been available, and second, we are providing baselines for NLP tasks (speech recognition, speech synthesis, and machine translation).",

The process of converting human spoken speech into text is performed by an Automatic Speech Recognition (ASR) engine. While functional examples of ASR with enterprise systems can be seen in day-to-day use, most of these work under constraints of a limited domain, and/or use of additional domain-specific cues to enhance the speech-to-text conversion process. Prior speech-and-natural language interfaces for such purposes have been rather restricted to either Interactive Voice Recognition (IVR) technology, or have focused on building a very specialized speech engine with domain specific terminology that recognizes key-words in that domain through an extensively customized language model, and trigger specific tasks in the enterprise application system. This makes the interface extremely specialized, rather cumbersome and non-adaptable for other domains. Further, every time a new enterprise application requires a speech and natural language interface, one has to redevelop the entire interface again.\nAn alternative to domain-specific speech recognition engines has been to re-purpose general-purpose speech recognition engines, such as Google Speech API, IBM Watson Speech to text API which can be used across domains with natural language question answering systems. Such general-purpose automatic speech engines (gp-ASR) are deep trained on very large general corpus using deep neural network (DNN) techniques. The deep learnt acoustic and language models enhance the performance of a ASR. However, this comes with its own limitations. For freely spoken natural language sentences, the typical recognition accuracy achievable even for state-of-the-art speech recognition systems have been observed to be about 60% to 90% in real-world environments BIBREF0 . The recognition is worse if we consider factors such as domain-specific words, environmental noise, variations in accent, poor ability to express on the part of the user, or inadequate speech and language resources from the domain to train such speech recognition systems. The subsequent natural language processing, such as that in a question answering system, of such erroneously and partially recognized text becomes rather problematic, as the domain terms may be inaccurately recognized or linguistic errors may creep into the sentence. It is, hence, important to improve the accuracy of the ASR output text.\nIn this paper, we focus on the issues of using a readily available gp-ASR and adapting its output for domain-specific natural language question answering BIBREF1 .

Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages?

As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM.

While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nOur data is collected in the form of conversations, providing better context.",

If your baby is not sleep trained, it will likely result in them waking up more often at night and needing the parent's help to soothe or rock them back to sleep. There are several methods you can use to sleep train your baby including the \"cry it out\" method, which works by allowing your child to cry while checking in on them incrementally to make sure they know you're there. When using the cry it out method, you need to ensure that all of your baby's needs have been met. Make sure your child is fed, changed, burped, and is overall comfortable. You can use words like \"it's sleepy time\" to signal your baby to sleep. This method takes about 4-7 days to work and has been proven to be the most effective and completely safe to use on your child.",

        "answer": "The application of deep learning methods for the task of hate speech detection.",
        "evidence": "With the massive increase in social interactions on online social networks, there has also been an increase of hateful activities that exploit such infrastructure. On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs). As baselines, we compare with feature spaces comprising of char n-grams BIBREF0 , TF-IDF vectors, and Bag of Words vectors (BoWV).\nMain contributions of our paper are as follows: (1) We investigate the application of deep learning methods for the task of hate speech detection. (2) We explore various tweet semantic embeddings like char n-grams, word Term Frequency-Inverse Document Frequency (TF-IDF) values, Bag of Words Vectors (BoWV) over Global Vectors for Word Representation (GloVe), and task-specific embeddings learned using FastText, CNNs and LSTMs. (3) Our methods beat state-of-the-art methods by a large margin ( INLINEFORM0 18 F1 points better).\n(1) We investigate the application of deep learning methods for the task of hate speech detection.",

        "answer": "The encoder module of transformer.",
        "evidence": "Shared-private feature extractor is mainly used for extracting shared features and private features among different tasks. In this paper, we apply the encoder module of transformer BIBREF16 (henceforth, transformer encoder) to the shared-private extractor of our model. Specially, we employ two transformer encoders to encode the input embeddings of the two tasks as their respective private features. A transformer encoder is used to encode simultaneously the input embeddings of the two tasks as shared features of both tasks. This process is illustrated by the shared-private layer of Figure FIGREF6. The red box in the middle denotes the extraction of shared features and the left and right boxes represent the extraction of private features of two tasks. Next, we take the extraction of the private feature of fake news detection as an example to elaborate on the process of transformer encoder.\nThe kernel of transformer encoder is the scaled dot-product attention, which is a special case of attention mechanism. It can be precisely described as follows:\nwhere ${\\rm \\textbf {Q}} \\in \\mathbb {R}^{l \\times (d_p+d_w)}$, ${\\rm \\textbf {K}} \\in \\mathbb {R}^{l \\times (d_p+d_w)}$, and ${\\rm \\textbf {V}} \\in \\mathbb {R}^{l \\times (d_p+d_w)}$ are query matrix, key matrix, and value matrix, respectively. In our setting, the query ${\\rm \\textbf {Q}}$ stems from the inputs itself, i.e., ${\\rm \\textbf {Q}}={\\rm \\textbf {K}}={\\rm \\textbf {V}}={\\rm \\textbf {E}}$.\nTo explore the high parallelizability of attention, transformer encoder designs a multi-head attention mechanism based on the scaled dot-product attention. More concretely, multi-head attention first linearly projects the queries, keys and values $h$ times by using different linear projections. Then $h$ projections perform the scaled dot-product attention in parallel. Finally, these results of attention are concatenated and once again projected to get the new representation. Formally, the multi-head attention can be formulated as follows:\nwhere ${\\rm \\textbf {W}}_i^Q \\in \\mathbb {R}^{(d_p+d_w) \\times d_k}$, ${\\rm \\textbf {W}}_i^K \\in \\mathbb {R}^{(d_p+d_w) \\times d_k}$, ${\\rm \\textbf {W}}_i^V \\in \\mathbb {R}^{(d_p+d_w) \\times d_k}$ are trainable projection parameters. $d_k$ is $(d_p+d_w)/h$, $h$ is the number of heads. In Eq.(DISPLAY_FORM11), ${\\rm \\textbf {W}}^o \\in \\mathbb {R}^{(d_p+d_w) \\times (d_p+d_w)}$ is also trainable parameter.\nShared-private feature extractor is mainly used for extracting shared features and private features among different tasks.

        "evidence": "",
        "answer": "There are ten commandments for effective presidential relationals.  I will discuss four of these commandments. The first that I will discuss is that the president should respect Congress as an equal institution. President Obama said, “If Congress doesn’t act, I will.”  He went on to use executive orders to enable the policy that he was trying to enact.  The problem with this method is that Trump was then able to revoke those acts, undoing all the work that Obama accomplished.  The second is bi-partisan support for Presidential programs.  If both sides take ownership of an issue, it tends to make it easier to enact policy.  Third, the President needs to be able to compromise.  If he can’t compromise, he won’t be able to effectively negotiate a bill with Congress.  Fourth is the President needs a sound program.  If the program has no chance of success, then Congress won’t want to back it.\nIf we define a President as being effective when he creates lasting policy, then he obviously needs to have a good relationship with Congress.  If he’s not able to work with Congress to pass legislation, then his only other option would be to use executive orders to enact policy, which will typically not live past his Presidency.",

        "question": "What is the basic idea in binary paragraph vector models?",
        "answer": "The basic idea in binary paragraph vector models is to introduce a sigmoid nonlinearity before the softmax that models the conditional probability of words given the context.",
        "evidence": "The basic idea in binary paragraph vector models is to introduce a sigmoid nonlinearity before the softmax that models the conditional probability of words given the context. If we then enforce binary or near-binary activations in this nonlinearity, the probability distribution over words will be conditioned on a bit vector context, rather than real-valued representation. The inference in the model proceeds like in Paragraph Vector, except the document code is constructed from the sigmoid activations. After rounding, this code can be seen as a distributed binary representation of the document.\nIn the simplest Binary PV-DBOW model (Figure FIGREF1 ) the dimensionality of the real-valued document embeddings is equal to the length of the binary codes. Despite this low dimensional representation – a useful binary hash will typically have 128 or fewer bits – this model performed surprisingly well in our experiments.\nNote that we cannot simply increase the embedding dimensionality in Binary PV-DBOW in order to learn better codes: binary vectors learned in this way would be too long to be useful in document hashing. The retrieval performance can, however, be improved by using binary codes for initial filtering of documents, and then using a representation with higher capacity to rank the remaining documents by their similarity to the query. BIBREF3 , for example, used semantic hashing codes for initial filtering and TF-IDF for ranking. A similar document retrieval strategy can be realized with binary paragraph vectors. Furthermore, we can extend the Binary PV-DBOW model to simultaneously learn short binary codes and higher-dimensional real-valued representations. Specifically, in the Real-Binary PV-DBOW model (Figure FIGREF2 ) we introduce a linear projection between the document embedding matrix and the sigmoid nonlinearity. During training, we learn the softmax parameters and the projection matrix. During inference, softmax weights and the projection matrix are fixed. This way, we simultaneously obtain a high-capacity representation of a document in the embedding matrix, e.g. 300-dimensional real-valued vector, and a short binary representation from the sigmoid activations.\nOne advantage of using the Real-Binary PV-DBOW model over two separate networks is that we need to store only one set of softmax parameters (and a small projection matrix) in the memory, instead of two large weight matrices. Additionally, only one model needs to be trained, rather than two distinct networks.\nBinary document codes can also be learned by extending distributed memory models. BIBREF7 suggest that in PV-DM, a context of the central word can be constructed by either concatenating or averaging the document vector and the embeddings of the surrounding words. However, in Binary PV-DM (Figure FIGREF3 ) we always construct the context by concatenating the relevant vectors before applying the sigmoid nonlinearity. This way, the length of binary codes is not tied to the dimensionality of word embeddings.\nSoftmax layers in the models described above should be trained to predict words in documents given binary context vectors. Training should therefore encourage binary activations in the preceding sigmoid layers. This can be done in several ways. In semantic hashing autoencoders BIBREF3 added noise to the sigmoid coding layer. Error backpropagation then countered the noise, by forcing the activations to be close to 0 or 1. Another approach was used by BIBREF12 in autoencoders that learned binary codes for small images. During the forward pass, activations in the coding layer were rounded to 0 or 1. Original (i.e. not rounded) activations were used when backpropagating errors. Alternatively, one could model the document codes with stochastic binary neurons. Learning in this case can still proceed with error backpropagation, provided that a suitable gradient estimator is used alongside stochastic activations. We experimented with the methods used in semantic hashing and Krizhevsky's autoencoders, as well as with the two biased gradient estimators for stochastic binary neurons discussed by BIBREF13 . We also investigated the slope annealing trick BIBREF14 when training networks with stochastic binary activations. From our experience, binary paragraph vector models with rounded activations are easy to train and learn better codes than models with noise-based binarization or stochastic neurons. We therefore use Krizhevsky's binarization in our models.\nThe basic idea in binary paragraph vector models is to introduce a sigmoid nonlinearity before the softmax that models the conditional probability of words given the context.",

        "answer": "It always falls into a computation-expensive and parameter vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation prob lem (Zhu et al. 2013).",
        "evidence": "In recent years, zero-shot translation in NMT has attracted widespread attention in academic research. Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.\nPivot-based Method is a common strategy to obtain a source$\\rightarrow $target model by introducing a pivot language. This approach is further divided into pivoting and pivot-synthetic. While the former firstly translates a source language into the pivot language which is later translated to the target language BIBREF4, BIBREF5, BIBREF12, the latter trains a source$\\rightarrow $target model with pseudo data generated from source-pivot or pivot-target parallel data BIBREF13, BIBREF14. Although the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter-vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation problem BIBREF15.\nTransfer Learning is firstly introduced for NMT by BIBREF6, which leverages a high-resource parent model to initialize the low-resource child model. On this basis, BIBREF7 and BIBREF8 use shared vocabularies for source/target language to improve transfer learning, while BIBREF16 relieve the vocabulary mismatch by mainly using cross-lingual word embedding. Although these methods are successful in the low-resource scene, they have limited effects in zero-shot translation.\nMultilingual NMT (MNMT) enables training a single model that supports translation from multiple source languages into multiple target languages, even those unseen language pairs BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21. Aside from simpler deployment, MNMT benefits from transfer learning where low-resource language pairs are trained together with high-resource ones. However, BIBREF22 point out that MNMT for zero-shot translation easily fails, and is sensitive to the hyper-parameter setting. Also, MNMT usually performs worse than the pivot-based method in zero-shot translation setting BIBREF23.\nUnsupervised NMT (UNMT) considers a harder setting, in which only large-scale monolingual corpora are available for training. Recently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training BIBREF24, BIBREF25, BIBREF26, BIBREF11. Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.\nOur proposed method belongs to the transfer learning, but it is different from traditional transfer methods which train a parent model as starting point. Before training a parent model, our approach fully leverages cross-lingual pre-training methods to make all source languages share the same feature space and thus enables a smooth transition for zero-shot translation.\nAlthough the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation prob lem (Zhu et al. 2013).",

Yet, most existing NMT training pipelines fail to fully take advantage of the very large volume of monolingual source and/or parallel data that is often available. Making a better use of data is particularly critical in domain adaptation scenarios, where parallel adaptation data is usually assumed to be small in comparison to out-of-domain parallel data, or to in-domain monolingual texts. This situation sharply contrasts with the previous generation of statistical MT engines BIBREF1 , which could seamlessly integrate very large amounts of non-parallel documents, usually with a large positive effect on translation quality.\nSuch observations have been made repeatedly and have led to many innovative techniques to integrate monolingual data in NMT, that we review shortly. The most successful approach to date is the proposal of BIBREF2 , who use monolingual target texts to generate artificial parallel data via backward translation (BT). This technique has since proven effective in many subsequent studies. It is however very computationally costly, typically requiring to translate large sets of data. Determining the “right” amount (and quality) of BT data is another open issue, but we observe that experiments reported in the literature only use a subset of the available monolingual resources. This suggests that standard recipes for BT might be sub-optimal.\nThis paper aims to better understand the strengths and weaknesses of BT and to design more principled techniques to improve its effects. More specifically, we seek to answer the following questions: since there are many ways to generate pseudo parallel corpora, how important is the quality of this data for MT performance? Which properties of back-translated sentences actually matter for MT quality? Does BT act as some kind of regularizer BIBREF3 ? Can BT be efficiently simulated? Does BT data play the same role as a target-side language modeling, or are they complementary? BT is often used for domain adaptation: can the effect of having more in-domain data be sorted out from the mere increase of training material BIBREF2 ? For studies related to the impact of varying the size of BT data, we refer the readers to the recent work of BIBREF4 .\nTo answer these questions, we have reimplemented several strategies to use monolingual data in NMT and have run experiments on two language pairs in a very controlled setting (see § SECREF2 ). Our main results (see § SECREF4 and § SECREF5 ) suggest promising directions for efficient domain adaptation with cheaper techniques than conventional BT.\nTo answer these questions, we have reimplemented several strategies to use monolingual data in NMT and have run experiments on two language pairs in a very controlled setting (see § SECREF2 ).",

        "answer": "Their proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using their method.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages.

Prior work has argued that machine learning may also benefit from interactive, multimodal learning BIBREF3 , BIBREF4 , BIBREF5 , termed virtual embodiment BIBREF6 . Driven by breakthroughs in static, unimodal tasks such as image classification BIBREF7 and language processing BIBREF8 , machine learning has moved in this direction. Recent tasks such as visual question answering BIBREF9 , image captioning BIBREF10 , and audio-video classification BIBREF11 make steps towards learning from multiple modalities but lack the dynamic, responsive signal from exploratory learning. Modern, challenging tasks incorporating interaction, such as Atari BIBREF12 and Go BIBREF13 , push agents to learn complex strategies through trial-and-error but miss information-rich connections across vision, language, sounds, and actions. To remedy these shortcomings, subsequent work introduces tasks that are both multimodal and interactive, successfully training virtually embodied agents that, for example, ground language in actions and visual percepts in 3D worlds BIBREF3 , BIBREF4 , BIBREF14 .\nFor virtual embodiment to reach its full potential, though, agents should be immersed in a rich, lifelike context as humans are. Agents may then learn to ground concepts not only in various modalities but also in relationships to other concepts, i.e. that forks are often in kitchens, which are near living rooms, which contain sofas, etc. Humans learn by concept-to-concept association, as shown in child learning psychology BIBREF1 , BIBREF2 , cognitive science BIBREF15 , neuroscience BIBREF16 , and linguistics BIBREF17 .

        "answer": "For standard approach, the only difference is not using an additional diversity loss. The remaining regularizers, e.g., data augmentation, weight decay etc, are all applied as specified per-experiment. we clarified this in the updated manuscript.",
        "evidence": "We start by evaluating our proposed diversity approach on two image datasets: CIFAR10 and CI-FAR100. We use our approach on three state-of-the-art CNNs: ResNext-29-08-16: we consider the standard ResNext Model with a 29-layer architecture, a cardinality of 8, and a width of 16. DenseNet-12: we use DenseNet with the 40layer architecture and a growth rate of 12. ResNet50: we consider the standard ResNet model with 50 layers. We compare against the standard networks 2 as well as networks trained with DeCov diversity strategy. For each approach the hyperparameters are selected based on the validation set. The full experimental setup is presented in the Appendix. We report the average performance over three random seeds. We note that, compared to the standard approach, employing a diversity strategy generally boosts the results for all the three models and that our approach consistency outperforms both competing For the hyperparameters, we use λ = 0.001 and γ = 10. The full experimental setup is presented in the Appendix. Table reports the test errors of the different diversity strategies. To study the effect of diversity on the generalization gap, we also report the final training errors and the generalization gap, i.e., training accuracy -test accuracy. As it can be seen, diversity (our approach and DeCov) reduces the test error of the model and yields a better performance. We note that, in accordance with our theoretical findings in Section 2, using diversity indeed reduces overfitting and decreases the empirical generalisation gap of neural networks. In fact, our logdet variant reduces the empirical generalization gap of the model by 1.8% compared to the standard approach. We note that our approach has a small additional time cost. For example for ResNet50, our direct, det and logdet variants take only 0.29%, 0.39%, and 0.49% extra training time, respectively.\nFigure: Sensitivity analysis of λ and γ on both the model accuracy and its generalization ability using ResNet50 trained on ImageNet.\nSensitivity analysis: To further investigate the effect of the proposed diversity strategy, we conduct a sensitivity analysis using ImageNet on the hyperparameters of our methods: γ, which is the RBF parameter used to measure the pairwise similarity between two units, and λ, which controls the contribution of the global diversity term to the global loss. We analyse the effect of the two parameters on both the final performance of the models and its generalization ability. The analysis is presented in Figure and in supplementary material. As it can be seen, promoting the within-layer diversity consistently reduces overfitting and decreases the generalization gap for most of the hyperparameters values. Moreover, we note that global modeling of diversity, i.e., det and logdet variants, yield tighter generalization gaps compared to the non-global direct approach. It is worth noting that Figure shows that there is a trade-off between the generalization gap and the final error. Emphasizing diversity and using a high weight for the diversity term significantly decreases the generalization gap, but this damages the performance of the model compared to the standard approach. For lower values of λ, the model is able to significantly outperform the standard approach on both the test error and the generalization gap.\nConnection to Theory: In Section 2, we provided theoretical bounds for the generalization errors of neural networks, which are inversely proportional to the diversity term, d min , the lower bound of\nTo show that the proposed regularizer indeed improves diversity, we track the empirical average of the aforementioned variable, i.e.,\n2 during the training. The results for both the standard approach and the logdet variant of our approach are reported in Figure. As it can be seen, our regularizer yields in higher diversity which reduces overfitting and leads to better generalization. Compatibility with Dropout: Dropout) is a popular regularization technique that, similarly to our approach, is applied on top of the layer output and has been known to improve generalization and reduce overfitting. Here, we evaluate the compatibility of our approach with Dropout. We add a Dropout regularizer with 20% rate on top the last intermediate representation layer of both ResNet50 and Wide-ResNet50. The results are reported in Table. We note that adding a diversity regularizer alongside the Dropout consistently yields lower error rates compared to only Dropout except for the det variant on Wide-ResNet50. For Wide-ResNet50, the combination of our logdet variant and Dropout leads to 0.53%, 0.25%, and 0.38% improvement compared to standard approach, Dropout only, and our logdet variant only, respectively.\nBeyond CNN models, we also evaluate the performance of our diversity strategy on modern attention-free, multi-layer perceptron (MLP) based models for image classification. Such models are known to exhibit high overfitting and require regularization. We evaluate how diversity affects the accuracy of such models on CIFAR10. In particular, we conduct a simple experiment using two models: MLP-Mixer, gMLP with four blocks each. The full description of the experimental setup is presented in the Appendix. The results in Table show that employing a diversity strategy can indeed improve the performance of these models thanks to its ability to learn rich and robust representation of the input.\nTransfer learning: Beyond standard classification, the proposed approach can be useful, e.g., in transfer learning, where the main goal is to 'transfer' previously learned representation to solve new tasks. Thus, learning a rich and diverse representation is beneficial and can lead to better transferability. To demonstrate this, we conduct another experiment, where we use ImageNet-pretrained ResNet50 models with the different diversity approaches and we finetune them to CIFAR10 and CIFAR100. The results are reported in Table. As it can be seen, employing a diversity strategy helps in the transfer learning context and leads consistently to lower error rates. For example, the log variant of our approach leads to 0.94% and 1.27% gains on CIFAR10 and CIFAR100, respectively. To further demonstrate the usefulness of promoting diversity, we test the robustness of our approach in the presence of label noise. In such situations, standard neural network tend to overfit to the noisy sample and not generalize well to the test set. Enforcing diversity can lead to better and richer representation attenuating the effect of noise. To show this, we performed additional experiments with label noise (20% and 40%) on CIFAR10 and CIFAR100 using ResNet50. The results are reported in Table. As it can be seen, in the presence of noise, the gap between the standard approach and diversity (Decov and ours) increases. For example, our logdet variant boosts the results by 1.71% and 3.59% on CIFAR10 and CIFAR100 with 40% noise, respectively.\nFor the standard approach, the only difference is not using an additional diversity loss.

        "evidence": "Categories such as animal or furniture are fundamental cognitive building blocks allowing humans to efficiently represent and communicate the complex world around them. Concepts (e.g., dog, table) are grouped into categories based on shared properties pertaining, for example, to their behavior, appearance, or function. Categorization underlies other cognitive functions such as perception BIBREF0 , BIBREF1 or language BIBREF2 , BIBREF3 , and there is evidence that categories are not only shaped by the world they represent, but also by the language through which they are communicated BIBREF4 , BIBREF5 . Although mental categories exist across communities and cultures, their exact manifestations differ BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . For example, American English speakers prefer taxonomic categorizations (e.g., mouse,squirrel) while Chinese speakers tend to prefer to categorize objects relationally (e.g., tree, squirrel; BIBREF7 ).\nGiven their prevalent function in human cognition, the acquisition and representation of categories has attracted considerable attention in cognitive science, and numerous theories have emerged BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . Empirical studies of category acquisition and representation, have been predominantly based on small-scale laboratory experiments. In a typical experiment, human subjects are presented with small sets of often artificial concepts, such as binary strings BIBREF14 or colored shapes BIBREF15 , with strictly controlled features BIBREF16 , BIBREF17 , BIBREF18 . Hypotheses and principles of human categorization are established based on the processes and characteristics of the categorizations produced by the participants. The distribution of subjects participating in such studies is often skewed towards members of cultural and socioeconomic groups which are prevalent in the environment where the research is conducted, and typically consists to a large proportion of western, educated, wealthy and English-speaking participants often sampled from the even more specific population of college students. The demographic and socioeconomic bias has been long recognized, and the question of how this bias might impact conclusions about human cognition in general BIBREF19 and category learning specifically is under active debate BIBREF9 . Although laboratory studies are invaluable for understanding categorization phenomena in a controlled environment, they are also expensive and time-consuming to conduct, and consequently problematic to scale.\nIn this work, we scale the investigation of category learning and representation along two axes: (1) the complexity of the learning environment, and consequently the richness of learnable concept and category representations, and (2) the diversity of languages and cultures considered in evaluation. We present a novel knowledge-lean, cognitively motivated Bayesian model which learns categories and their structured features jointly from large natural language text corpora in five diverse languages: Arabic, Chinese, English, French, and German. We approximate the learning environment using large corpora of natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Besides text corpora can cover arbitrarily semantically complex domains, and are available across languages, providing an ideal test environment for studying categorization at scale.\nFigure 1 illustrates example input to our model, and Figure 2 shows example categories and associated features as induced by our model from the English Wikipedia. Following prior work BIBREF21 , BIBREF22 , we create language-specific sets of stimuli, each consisting of a mention of target concept (e.g., apple), within its local linguistic context (e.g., {contains, seeds}; cf., Figure 1 ). We consider each stimulus an observation of the concept, i.e., the word referring to the concept is an instance of the concept itself, and its context words are a representation of its features. Our model infers categories as groups of concepts occurring with similar features; and it infers feature types as groups of features which co-occur with each other. The output of our model (cf., Figure 2 ) are categories as clusters of concepts, each associated with a set of feature types, i.e., thematically coherent groups of features. We train a separate model on each of our target languages, each time presenting the model with input stimuli from the relevant language.\nComputational models in general, and Bayesian models in particular, allow to investigate hypotheses about cognitive phenomena by systematically modifying the learning mechanism or available input while observing the learning outcome. Bayesian models have been applied to a variety of cognitive phenomena BIBREF23 , BIBREF24 , BIBREF25 , and category acquisition is no exception. Following from Anderson's BIBREF14 , BIBREF26 , BIBREF27 seminal work, a number of models have been developed, and tested in their ability to reproduce human behavior in laboratory settings by exposing the models to small sets of controlled inputs with restricted features. In this work we draw on the full potential of computational modeling by exposing our models to (a) more complex data reflecting the diversity of contexts in which concepts can be observed; and (b) a input data in different languages, shedding light on the applicability of computational cognitive models beyond the prevalent English test language.\nCategorization tasks in a laboratory environment typically involve stimuli with a small set of features which are relevant to the categorization target, eliminating the need to detect features, and discriminate them in their relevance. In the real world, however, concepts are observed in contexts and a substantial part of acquiring categorical knowledge involves learning which features are useful to discriminate among concepts. In fact, research has shown that humans learn features jointly with categories BIBREF28 , BIBREF29 and that these features are themselves structured so as to represent the diversity and complexity of the properties exhibited in the world BIBREF30 , BIBREF31 , BIBREF32 . Our novel model of category learning presented in this article, jointly learns categories and their structured features from large sets of informationally rich data.\nOur work exemplifies the opportunities that arise from computational models and large data sets for investigating the mechanisms with which conceptual representations emerge, as well as the representations themselves in a broader context. We simulate the acquisition of categories comprising hundreds of concepts by approximating the learning environment with natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , as well as human-like biases BIBREF33 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Text corpora are a prime example of naturally occurring large-scale data sets BIBREF34 , BIBREF35 , BIBREF36 . In analogy to real-world situations, they encapsulate rich, diverse, and potentially noisy, information. The wide availability of corpora allows us to train and evaluate cognitive models on data from diverse languages and cultures. We test our model on corpora from five languages, derived from the online encyclopedia Wikipedia in Arabic, Chinese, French, English, and German. Wikipedia is a valuable resource for our study because it (a) discusses concepts and their properties explicitly and can thus serve as a proxy for the environment speakers of a language are exposed to; and (b) allows us to construct corpora which are highly comparable in their content across languages, controlling for effects of genre or style.\nWe present a series of evaluations investigating the quality of the induced categories and features. Leveraging a reference comprising hundreds of concepts and more than 30 categories, we demonstrate that our model learns meaningful categories in all five target languages. We furthermore show, through crowd-sourced evaluations involving native speakers of each target language, that the induced feature types are (a) each thematically coherent and interpretable; and (b) are associated with categories in comprehensible ways. We discuss language-specific idiosyncrasies emerging from the induced representations.\nIn the remainder of this article, we first review related literature, before we present a cognitively motivated model for learning categories and their structured representations from large natural language corpora. We then evaluate the quality of the emerging representations, as well as the generalizability of our model across languages. Note that the primary goal of this work is not to characterize differences in categories and features arising from different languages (even though this would be an interesting avenue for future work). Rather, we aim to demonstrate the utility of large-scale naturalistic datasets for cognitive modeling, and to verify mechanisms of categorization known from laboratory studies at scale and across communities.\nOur experiments indicate that the proposed method outperforms neural language models trained with well-tuned hyperparameters and achieves state-of-the-art scores on each dataset.",

With a similar aim, ren2013combine first compute the n best constituency trees using a probabilistic context-free grammar, convert those into dependency trees using a dependency model, compute a probability score for each of them, and finally rerank the most plausible trees based on both scores.

        "question": "What is the accuracy of discriminating between PD patients and HC subjects",
        "answer": "88%.",
        "evidence": "Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the mid-brain producing several motor and non-motor impairments in the patients BIBREF0. Motor symptoms include among others, bradykinesia, rigidity, resting tremor, micrographia, and different speech impairments. The speech impairments observed in PD patients are typically grouped as hypokinetic dysarthria, and include symptoms such as vocal folds rigidity, bradykinesia, and reduced control of muscles and limbs involved in the speech production. The effects of dysarthria in the speech of PD patients include increased acoustic noise, reduced intensity, harsh and breathy voice quality, increased voice nasality, monopitch, monoludness, speech rate disturbances, imprecise articulation of consonants BIBREF1, and involuntary introduction of pauses BIBREF2. Clinical observations in the speech of patients can be objectively and automatically measured by using computer aided methods supported in signal processing and pattern recognition with the aim to address two main aspects: (1) to support the diagnosis of the disease by classifying healthy control (HC) subjects and patients, and (2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.\nMost of the studies in the literature to classify PD from speech are based on computing hand-crafted features and using classifiers such as support vector machines (SVMs) or K-nearest neighbors (KNN). For instance, in BIBREF3, the authors computed features related to perturbations of the fundamental frequency and amplitude of the speech signal to classify utterances from 20 PD patients and 20 HC subjects, Turkish speakers. Classifiers based on KNN and SVMs were considered, and accuracies of up to 75% were reported. Later, in BIBREF4 the authors proposed a phonation analysis based on several time frequency representations to assess tremor in the speech of PD patients. The extracted features were based on energy and entropy computed from time frequency representations. Several classifiers were used, including Gaussian mixture models (GMMs) and SVMs. Accuracies of up to 77% were reported in utterances of the PC-GITA database BIBREF5, formed with utterances from 50 PD patients and 50 HC subjects, Colombian Spanish native speakers. The authors from BIBREF6 computed features to model different articulation deficits in PD such as vowel quality, coordination of laryngeal and supra-laryngeal activity, precision of consonant articulation, tongue movement, occlusion weakening, and speech timing. The authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier. Additional articulation features were proposed in BIBREF7, where the authors modeled the difficulty of PD patients to start/stop the vocal fold vibration in continuous speech. The model was based on the energy content in the transitions between unvoiced and voiced segments. The authors classified PD patients and HC speakers with speech recordings in three different languages (Spanish, German, and Czech), and reported accuracies ranging from 80% to 94% depending on the language; however, the results were optimistic, since the hyper-parameters of the classifier were optimized based on the accuracy on the test set. Another articulation model was proposed in BIBREF8. The authors considered a forced alignment strategy to segment the different phonetic units in the speech utterances. The phonemes were segmented and grouped to train different GMMs. The classification was performed based on a threshold of the difference between the posterior probabilities from the models created for HC subjects and PD patients. The model was tested with Colombian Spanish utterances from the PC-GITA database BIBREF5 and with the Czech data from BIBREF9. The authors reported accuracies of up to 81% for the Spanish data, and of up to 94% for the Czech data.\nIn addition to the hand-crafted feature extraction models, there is a growing interest in the research community to consider deep learning models in the assessment of the speech of PD patients BIBREF10, BIBREF11, BIBREF12. Deep learning methods have the potential to extract more abstract and robust features than those manually computed. These features could help to improve the accuracy of different models to classify pathological speech, such as PD BIBREF13. A deep learning based articulation model was proposed in BIBREF11 to model the difficulties of the patients to stop/start the vibration of the vocal folds. Transitions between voiced and unvoiced segments were modeled with time-frequency representations and convolutional neural networks (CNNs). The authors considered speech recordings of PD patients and HC speakers in three languages: Spanish, German, and Czech, and reported accuracies ranging from 70% to 89%, depending on the language. However, in a language independent scenario, i.e., training the CNN with utterances from one language and testing with the remaining two, the results were not satisfactory (accuracy$<60\\%$).\nThe classification of PD from speech in different languages has to be carefully conducted to avoid bias towards the linguistic content present in each language. For instance, Czech and German languages are richer than Spanish language in terms of consonant production, which may cause that it is easier to produce consonant sounds by Czech PD patients than by Spanish PD patients. Despite these language dependent issues, the results in the classification of PD in different languages could be improved using a transfer learning strategy among languages, i.e., to train a base model with utterances from one language, and then, to perform a fine-tuning of the weights with utterances from the target language BIBREF14. Similar approaches based on transfer learning have been recently considered to classify PD using handwriting BIBREF15. In the present study, we propose a methodology to classify PD via a transfer learning strategy with the aim to improve the accuracy in different languages. CNNs trained with utterances from one language are used to initialize a model to classify speech utterances from PD patients in a different language. The models are evaluated with speech utterances in Spanish, German, and Czech languages. The results suggest that the use of a transfer learning strategy improved the accuracy of the models over 8% with respect to those obtained when the model is trained only with utterance from the target language.\nThe authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier.",

There are few ways to do it but the easiest one for the home is to pre-ferment a small portion of equal amounts of water and flour.\n\nFor example, start with separating out the total ingredients: 1000g flour, 650g water, 30g salt, 5g dry yeast. This will result in 1680g of dough enough for ~8 medium pizzas. Mix 200g of water, flour and the yeast and let it sit on counter for an hour. Then move to the refrigerator for slow fermentation for ~24h. Take this out and add the remaining ingredients. Kneed until smooth, and let it rest on the counter for 1h.

        "question": "Based on the following passage, what did Albert Einstein publish in 1905?",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

Large news portals often employ moderators, who are frequently overwhelmed by the volume and abusiveness of comments. Readers are disappointed when non-abusive comments do not appear quickly online because of moderation delays. Smaller news portals may be unable to employ moderators, and some are forced to shut down their comments.\nIn previous work BIBREF0 , we introduced a new dataset of approx. 1.6M manually moderated user comments from a Greek sports news portal, called Gazzetta, which we made publicly available.

In 1995, Mano Ya Na Mano was selected by Zee TV and her music-based show Dhun Dhamaka was chosen by Doordarshan. Her 1995 sitcom, Hum Paanch was her first success.\n\nIn the 2000s, the letter 'K' became her lucky alphabet and she launched many shows with the first word of every title starting with the same letter, including Kyunki Saas Bhi Kabhi Bahu Thi, which broke all records to become the series to attract the highest TRPs in 2000. Other shows beginning with 'K' include Kahaani Ghar Ghar Ki, Kabhii Sautan Kabhii Sahelii, Kohi Apna Sa, Kaahin Kissii Roz, Kalash, Kasautii Zindagii Kay, Kahiin To Hoga and Kasamh Se. In 2001, she was awarded the title of Best Entrepreneur of the Year.\n\nBy July 2001, Kapoor was producing more than 30 hours of television shows per week. 20 of her 34 serials were listed as the most popular serials, across all major TV channels like Zee TV, Sony, Star Plus and Metro.

WMT2018 is used as out-of-domain training data which consists of 41M sentence pairs.\nData preprocessing: For speech data, the utterances are segmented into multiple frames with a 25 ms window size and a 10 ms step size. Then we extract 80-channel log-Mel filter bank and 3-dimensional pitch features using Kaldi BIBREF14, resulting in 83-dimensional input features. We normalize them by the mean and the standard deviation on the whole training set. The utterances with more than 3000 frames are discarded. The transcripts in ST-TED are in true-case with punctuation while in TED-LIUM2, transcripts are in lower-case and unpunctuated. Thus, we lowercase all the sentences and remove the punctuation to keep consistent. To increase the amount of training data, we perform speed perturbation on the raw signals with speed factors 0.9 and 1.1. For the text translation data, sentences longer than 80 words or shorter than 10 words are removed. Besides, we discard pairs whose length ratio between source and target sentence is smaller than 0.5 or larger than 2.0. Word tokenization is performed using the Moses scripts and both English and German words are in lower-case.\nWe use two different sets of vocabulary for our experiments. For the subword experiments, both English and German vocabularies are generated using sentencepiece BIBREF15 with a fixed size of 5k tokens. BIBREF9 inaguma2018speech show that increasing the vocabulary size is not helpful for ST task. For the character experiments, both English and German sentences are represented in the character level.\nFor evaluation, we segment each audio with the LIUM SpkDiarization tool BIBREF16 and then perform MWER segmentation with RWTH toolkit BIBREF17.

        "evidence": "Judo (Japanese: 柔道, Hepburn: Jūdō, lit. 'gentle way') is an unarmed modern Japanese martial art, Olympic sport (since 1964), and the most prominent form of jacket wrestling competed internationally. Judo was created in 1882 by Kanō Jigorō (嘉納 治五郎) as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on \"randori\" (乱取り, lit. 'free sparring') instead of \"kata\" (pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over established jujutsu schools in tournaments hosted by the Tokyo Metropolitan Police Department (警視庁武術大会, Keishicho Bujutsu Taikai), resulting in its adoption as the department's primary martial art. A judo practitioner is called a \"judoka\" (柔道家, jūdōka, lit. 'judo performer'), and the judo uniform is called \"judogi\" (柔道着, jūdōgi, lit. 'judo attire').\n\nThe objective of competitive judo is to throw an opponent, immobilize them with a pin, or force an opponent to submit with a joint lock or a choke. While strikes and use of weapons are included in some pre-arranged forms (kata), they are not frequently trained and are illegal in judo competition or free practice. Judo's international governing body is the International Judo Federation, and competitors compete in the international IJF professional circuit.\n\nJudo's philosophy revolves around two primary principles: \"Seiryoku-Zenyo\" (精力善用, lit. 'good use of energy') and \"Jita-Kyoei\" (自他共栄, lit. 'mutual welfare and benefit'). The philosophy and subsequent pedagogy developed for judo became the model for other modern Japanese martial arts that developed from koryū (古流, traditional schools). Judo also spawned a number of derivative martial arts around the world, such as Brazilian jiu-jitsu, Krav Maga, sambo, and ARB. Judo also influenced other combat styles such as close-quarters combat (CQC), mixed martial arts (MMA), shoot wrestling and submission wrestling.",

        "evidence": "In the research field of Natural Language Processing (NLP) there are several tasks that contribute to understanding natural text. These tasks can manipulate natural language, such as tokenization process, and consequently can be used in other implementations, in order to extract syntactic or semantic information. One such task for syntactic components is Part of Speech Tagging (POS Tagging). Part of Speech Tagging in corpus linguistics is a process where a word is assigned with a label of the grammatical term, given the context it appears in. In many languages, POS Tagging models achieve an accuracy of 96 to 97 percent BIBREF0.\nPart of Speech Tagging for highly inflective languages, such as Greek is quite a difficult task. In the Greek Language, words can have different morphological forms, depending on the part of speech (verbs have up to ten different forms). For that purpose, there is a need for a tagset that can support morphological features for improvement of Greek POS Tagging BIBREF1.\nAnother main task for extracting semantic information is Named Entity Recognition (NER). Named Entity Recognition is a process where a word or a set of words reference to a world object. Most Natural Language Processing models classify named entities that describe people, locations, organizations, following the ENAMEX type or can be more complex by detecting numerical types, like percentages (NUMEX) or dates (TIMEX) BIBREF2.\nThe greek Part of Speech Tagging and Named Entity Recognition models presented in this paper were developed using the spaCy library BIBREF3. SpaCy is an open source, Natural Language Processing library that supports a variety of tasks, including POS Tagging, Named Entity Recognition, Dependency Parsing, etc. SpaCy uses sophisticated neural network-based models for the implementation of Natural Language Processing components that achieve state-of-the-art results in many of these tasks.\nIn the following chapters the process for implementing Part of Speech Tagging and Named Entity Recognition for the Greek Language is explained. A dataset with extended POS Tags was found and matched to a set of morphological rules, according to a treebank. The dataset was then processed, fed to the spaCy model and used for training. Similarly, for Named Entity Recognition, datasets from different sources were compared to a custom set of rules for named entities. Finally, different experiments were conducted for evaluating the accuracy of the models.\nPart of Speech Tagging in corpus linguistics is a process where a word is assigned with a label of the grammatical term, given the context it appears in.",

Vaughan used a custom set of uncommonly heavy strings, gauges .013, .015, .019, .028, .038, .058, and tuned a half-step below standard tuning. With these heavy string sizes, it was not uncommon for him to separate his fingernail because of his quick movement along the strings. The owner of an Austin club recalled Vaughan coming into the office between sets to borrow super glue, which he used to keep a fingernail split from widening while he continued to play. The super glue was suggested by Rene Martinez, who was Stevie's guitar technician. Martinez eventually convinced Stevie to change to slightly lighter strings. He preferred a guitar neck with an asymmetrical profile (thicker at the top), which was more comfortable for his thumb-over style of playing. Heavy use of the vibrato bar necessitated frequent replacements; Vaughan often had his roadie, Byron Barr, obtain custom stainless steel bars made by Barr's father. As for his usage of plectrums, Vaughan preferred Fender medium gauge guitar picks, using one of the rounder shoulders of the pick rather than the pointed tip to pluck and strum the strings.",

        "evidence": "Several promising approaches to interpreting RNNs have been developed recently. BIBREF3 have approached this by using gradient boosting trees to predict LSTM output probabilities and explain which features played a part in the prediction. They do not model the internal structure of the LSTM, but instead approximate the entire architecture as a black box. BIBREF4 showed that in LSTM language models, around 10% of the memory state dimensions can be interpreted with the naked eye by color-coding the text data with the state values; some of them track quotes, brackets and other clearly identifiable aspects of the text. Building on these results, we take a somewhat more systematic approach to looking for interpretable hidden state dimensions, by using decision trees to predict individual hidden state dimensions (Figure 2 ). We visualize the overall dynamics of the hidden states by coloring the training data with the k-means clusters on the state vectors (Figures 3 , 3 ).\nWe interpret the HMM and LSTM states in the hybrid algorithm with 10 LSTM state dimensions and 10 HMM states in Figures 3 and 3 , showing which features are identified by the HMM and LSTM components. In Figures 3 and 3 , we color-code the training data with the 10 HMM states. In Figures 3 and 3 , we apply k-means clustering to the LSTM state vectors, and color-code the training data with the clusters. The HMM and LSTM states pick up on spaces, indentation, and special characters in the data (such as comment symbols in Linux data). We see some examples where the HMM and LSTM complement each other, such as learning different things about spaces and comments on Linux data, or punctuation on the Shakespeare data. In Figure 2 , we see that some individual LSTM hidden state dimensions identify similar features, such as comment symbols in the Linux data.\nBuilding on these results, we take a somewhat more systematic approach to looking for interpretable hidden state dimensions, by using decision trees to predict individual hidden state dimensions (Figure 2 ).

Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time.

        "evidence": "State-of-the-art automatic speech recognition (ASR) systems BIBREF0 have large model capacities and require significant quantities of training data to generalize. Labeling thousands of hours of audio, however, is expensive and time-consuming. A natural question to ask is how to achieve better generalization with fewer training examples. Active learning studies this problem by identifying and labeling only the most informative data, potentially reducing sample complexity. How much active learning can help in large-scale, end-to-end ASR systems, however, is still an open question.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores. In particular, an utterance is considered informative if the most likely prediction has small probability BIBREF1 , or if the predictions are distributed very uniformly over the labels BIBREF2 . Though confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) BIBREF3 , where the informativeness is measured by the norm of the gradient incurred by the instance. EGL has previously been justified as intuitively measuring the expected change in a model's parameters BIBREF3 .We formalize this intuition from the perspective of asymptotic variance reduction, and experimentally, we show EGL to be superior to confidence-based methods on speech recognition tasks. Additionally, we observe that the ranking of samples scored by EGL is not correlated with that of confidence scoring, suggesting EGL identifies aspects of an instance that confidence scores cannot capture.\nIn BIBREF3 , EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular. Gradient-based methods have also found applications outside active learning. For example, BIBREF4 suggests that in stochastic gradient descent, sampling training instances with probabilities proportional to their gradient lengths can speed up convergence. From the perspective of variance reduction, this importance sampling problem shares many similarities to problems found in active learning.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores.",

In general, regression coefficients are not identifiable without any additional assumptions.

Noticing the probabilistic equation (7), we figured out how to identify the regression coefficients when the linearity assumption holds in the logistic regression.

Other principal stratum causal effects can be estimated in a similar fashion. Our approach can play an important role in a sensitivity analysis. Identification of causal effects is achieved through two assumptions. First, a subject who responds under the control would respond if given the treatment. This monotonicity assumption could prove valuable and can be justified in many scenarios that the additional therapy would help to improve the response. When the auxiliary variable X is discrete, we can identify and estimate Pr{S(1) = 1|S(0) = 0, X} under the monotonicity assumption.

It is recognized that no diagnostic tool is available to verify the validity of this counterfactual model.\nIn the motivating dataset, we discretize a continuous baseline variable into several levels. In practice, the linearity assumption may not hold. We would consider a two-pronged approach: 1) to estimate G L (x) and G R (x, y) by nonparametric estimates such as spline or kernel density estimates for a univariate continuous X; 2) to use a more flexible model for the counterfactual response such as a logistic regression with natural cubic spline with fixed and even-spaced knots along the domain of X. For each given x, we can still use the same probabilistic argument to link those estimates and the model parameters. The objective function would be a weighted sum of the squared difference of those probabilistic estimates.\nThen p 00x is the proportion of non-respondents among all subjects with X = x; p 11x is the proportion of respondents among all subjects with X = x.\nThe identifiability of model parameter β depends on the availability of ax = Pr{S(1) = 1|S(0) = 0, X = x} and b_xy = Pr{Y (0) = y|S(0) = 0, X = x}, for x ∈ Γ; y = 0, 1.****Identification of causal effects is achieved through two assumptions.

        "evidence": "The softmax function, a.k.a. softargmax, is a normalization function often used as the last activation function of a neural network\nwhere q i ∈ [0, 1] and i q i = 1. Thus, the normalized output vector can be interpreted as marginal probabilities. The softmax output can be naturally combined with the cross entropy function J = − i p i log q i , where p i is the target probability. The derivative of J with respect to z i takes a simple form of q i − p i. The simple probabilistic interpretation and derivative computation make the combination of softmax normalization and cross entropy loss a pervasive choice for multinomial classification problems. However, potential issues using softmax normalization with the backpropagation (BP) algorithm has not been fully investigated.\nSuppose a neural network G can be decomposed into two or more smaller subnetworks\nThe final activation Z is the superposition of the subnetwork activation before the softmax normalization in the output layer\nwhere f m is the non-linear function representing subnetwork G m . The decomposition is done according to the final activation without considering intermediate hidden layers. The softmax normalization operation has the following properties regarding the relationship between subnetwork activations (see Appendix A).\n1. If the subnetwork activations are linear offset versions of each other, such that Y\n, the normalization operation is equivalent to applying the softmax function to the scaled principal subnetwork: Q = softmax(SY 0 ), where S = 1 + α 1 + α 2 + • • • . The softmax normalization allows proportional integration of information. A single subnetwork that has very strong activation (higher prediction probabilities) can dominate over other subnetworks with weak activations. If there are no dominant subnetworks, the total number of contributing subnetworks may be large and the whole network tends to be overparameterized.\nIn short, the softmax function can act as a super combinator for different modes of the neural network, summing and amplifying weak subnetwork activations. This could partially explain why deep neural networks are so expressive that they are suitable for diverse types of problems. However, when there are redundant subnetworks that produce linearly correlated activations, the softmax normalization function make them indistinguishable from each other. The linearly correlated subnetworks potentially lead to overfitting and overparameterization. We have the following hypothesis regarding the effects of such redundant subnetworks: Hypothesis 1: For deep neural networks, the existence of redundant subnetworks combining with softmax normalization can lead to overfitting and overparameterization when training with the backpropagation algorithm.\nThe derivative of the cross entropy loss is linear with regard to the softmax output Q and target P , and softmax normalization makes it impossible to differentiate between the effects of different subnetworks, the BP algorithm thus will fine-tune all the parameters without penalizing any individual subnetwork. Therefore, the initialization of weights may create redundant subnetworks that have non-deterministic effects on the training process. For example, demonstrated that initialization of weights can affect test accuracy.

        "evidence": "In recent years, zero-shot translation in NMT has attracted widespread attention in academic research. Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.\nPivot-based Method is a common strategy to obtain a source$\\rightarrow $target model by introducing a pivot language. This approach is further divided into pivoting and pivot-synthetic. While the former firstly translates a source language into the pivot language which is later translated to the target language BIBREF4, BIBREF5, BIBREF12, the latter trains a source$\\rightarrow $target model with pseudo data generated from source-pivot or pivot-target parallel data BIBREF13, BIBREF14. Although the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter-vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation problem BIBREF15.\nTransfer Learning is firstly introduced for NMT by BIBREF6, which leverages a high-resource parent model to initialize the low-resource child model. On this basis, BIBREF7 and BIBREF8 use shared vocabularies for source/target language to improve transfer learning, while BIBREF16 relieve the vocabulary mismatch by mainly using cross-lingual word embedding. Although these methods are successful in the low-resource scene, they have limited effects in zero-shot translation.\nMultilingual NMT (MNMT) enables training a single model that supports translation from multiple source languages into multiple target languages, even those unseen language pairs BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21. Aside from simpler deployment, MNMT benefits from transfer learning where low-resource language pairs are trained together with high-resource ones. However, BIBREF22 point out that MNMT for zero-shot translation easily fails, and is sensitive to the hyper-parameter setting. Also, MNMT usually performs worse than the pivot-based method in zero-shot translation setting BIBREF23.\nUnsupervised NMT (UNMT) considers a harder setting, in which only large-scale monolingual corpora are available for training. Recently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training BIBREF24, BIBREF25, BIBREF26, BIBREF11. Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.\nOur proposed method belongs to the transfer learning, but it is different from traditional transfer methods which train a parent model as starting point.

        "evidence": "Just like any other field, the legal domain is facing multiple challenges in the era of digitisation. Document collections are growing at an enormous pace and their complete and deep analysis can only be tackled with the help of assisting technologies. This is where content curation technologies based on text analytics come in rehm2016j. Such domain-specific semantic technologies enable the fast and efficient automated processing of heterogeneous document collections, extracting important information units and metadata such as, among others, named entities, numeric expressions, concepts and topics, time expressions, and text structure. One of the fundamental processing tasks is the identification and categorisation of named entities (Named Entity Recognition, NER). Typically, NER is focused upon the identification of semantic categories such as person, location and organization but, especially in domain-specific applications, other typologies have been developed that correspond to task-, language- or domain-specific needs. With regard to the legal domain, the lack of freely available datasets has been a stumbling block for text analytics research. German newspaper datasets from CoNNL 2003 BIBREF0 or GermEval 2014 BIBREF1 are simply not suitable in terms of domain, text type or semantic categories covered.\nThe work described in this paper was carried out under the umbrella of the project Lynx: Building the Legal Knowledge Graph for Smart Compliance Services in Multilingual Europe, a three-year EU-funded project that started in December 2017 BIBREF2. Its objective is the creation of a legal knowledge graph that contains different types of legal and regulatory data BIBREF3, BIBREF4, BIBREF5. Lynx aims to help European companies, especially SMEs, that want to become active in new European countries and markets. The project offers compliance-related services that are currently tested and validated in three use cases (UC): (i) UC1 aims to analyse contracts, enriching them with domain-specific semantic information (document structure, entities, temporal expressions, claims, summaries, etc.); (ii) UC2 focuses on compliance services related to geothermal energy operations, where Lynx supports the understanding of regulatory regimes, including norms and standards; (iii) UC3 is a compliance solution in the domain of labour law, where legal provisions, case law, and expert literature are interlinked, analysed, and compared to define legal strategies for legal practice. The Lynx services are developed for several European languages including English, Spanish, and – relevant for this paper – German BIBREF6.\nDocuments in the legal domain contain multiple references to named entities, especially domain-specific named entities, i. e., jurisdictions, legal institutions, etc. Legal documents are unique and differ greatly from newspaper texts. On the one hand, the occurrence of general-domain named entities is relatively rare. On the other hand, in concrete applications, crucial domain-specific entities need to be identified in a reliable way, such as designations of legal norms and references to other legal documents (laws, ordinances, regulations, decisions, etc.). However, most NER solutions operate in the general or news domain, which makes them inapplicable to the analysis of legal documents BIBREF7, BIBREF8. Accordingly, there is a great need for an NER-annotated dataset consisting of legal documents, including the corresponding development of a typology of semantic concepts and uniform annotation guidelines. In this paper, we describe the development of a dataset of legal documents, which includes (i) named entities and (ii) temporal expressions.\nThe remainder of this article is structured as follows. First, Section SECREF3 gives a brief overview of related work. Section SECREF4 describes, in detail, the rationale behind the annotation of the dataset including the different semantic classes annotated. Section SECREF5 describes several characteristics of the dataset, followed by a short evaluation (Section SECREF6) and conclusions as well as future work (Section SECREF7).\nThe project offers compliance-related services that are currently tested and validated in three use cases (UC): (i) UC1 aims to analyse contracts, enriching them with domain-specific semantic information (document structure, entities, temporal expressions, claims, summaries, etc.); (ii) UC2 focuses on compliance services related to geothermal energy operations, where Lynx supports the understanding of regulatory regimes, including norms and standards; (iii) UC3 is a compliance solution in the domain of labour law, where legal provisions, case law, and expert literature are interlinked, analysed, and compared to define legal strategies for legal practice.",

        "question": "Why should people convert lawns and ornamental gardens to native plants?",
        "evidence": "",
        "answer": "Who doesn’t love butterflies? They are a beautiful symbol of innocence. But have you noticed there are fewer and fewer every year? When I was a kid, you couldn’t take a trip without getting some butterflies on the windshield of your car. So why are there so few and what does it mean?\n\nOne of the main reasons is the use of pesticides and herbicides. These chemicals are indiscriminate killers. And they knock the whole ecosystem out of balance. In my yard, I have seen how a little patience will put things back into balance. I had aphids, but slowly noticed aphid predators solving the problem. I had flies due to my chicken coop, but over a few weeks I saw Swallows and Phoebes move in to take advantage of the food source.\n\nThe other reason we see fewer butterflies is food for caterpillars. Most butterflies and moths (or butterflies of the night as I like to call them) need a particular plant to host their caterpillars. For Monarch butterflies, it is Milkweed (Asclepias), which is an unfortunate name for a beautiful plant. For Pipevine Swallowtails, it is Pipevine (Aristolochia). Without these plants, caterpillars have no source of food. And as cities and suburbs become paved over, there is no place for these once abundant plants to grow. As we look at our own yards, they contain beautiful plants that are imported from other places. But to a butterfly, our yards seem like deserts. Even plants like bottlebrush, which attract a lot of insects for nectar, provide no food for native baby insects. It’s kind of like having a bar for the adults to drink at, but no food to nourish their children so they can grow to be adults too. \n\nBut Doug Tallamy, an entomologist from University of Delaware, says we can help. By putting some native plants in our yards, we can provide the food to bring back butterflies.\n\nAs we prepared to redo our garden from evergreen ornamentals, to an English cottage/cut flower garden, something happened. We saw Doug Tallamy speak on a CNPS Silicon Valley Zoom Meeting. And we realized we had to change our direction, and begin gardening with natives. \n\nAs we look at our garden, the key is that we are just beginning…\nIt is a grand experiment to see what works where. And already the garden is talking to us. The blue eyed grass has jumped the paved walkway to another part of the garden! We expect more movement and magic in the future. Here are some of our thoughts on our garden.\n\nBlessings… Having a giant oak tree in our yard and creek behind us have certainly given us a leg up in terms of food and wildlife access to our yard.\n\nDownside… Lots of shade. Only two, maybe three spots in our garden that get good sun. So, we troll through Calscape looking for plants that will tolerate shade. (If you haven't met Calscape you are in for a treat. I hope you live in California though...).\n\nGoal… As Talamites, we believe in feeding the ecosystem, which starts with caterpillar farming. So how has that worked out? Well, we’ve only seen one or two caterpillars so far. Sigh. It’s all an experiment…\n\nBiggest impact… Leaving the leaves the past year. We can already see the soil improving, and everytime we water we see lots of insects rising up out of the litter. So it is happening. Slowly…\n\nSo we continue to replace non-natives with natives. Last weekend we took out Sarcococca and Pierris Japonicas and replaced them with Coffeeberry (Frangula Californica). This weekend we removed two maple trees and replaced them with Bush Anemone (Carpenteria Californica). And next weekend we are going to replace our box hedge with Coyote Brush (Baccharis pilularis). \n\nBesides the bugs, we've seen lots of other great wildlife in our yard. A new nest of baby squirrels is born in the tree every year. And this year we were surprised by 3 baby raccoons moving into the tree (it is largely hollow).\n\nThey are sweet shy and adorable. We've enjoyed watching them come out and scour the tree every night for food.",

Tiger Woods opened the door for an entire generation of young players coming from diverse backgrounds. This is a fundamental change to a sport that is historically a game of privilege and aristocracy. \n\nI would argue that the combination of having a winning record in Major events and having a significant cultural impact on the game makes Tiger Woods the greatest and most influential golfer of all time.",

        "evidence": "Although internet users accept unilateral contracts such as terms of service on a regular basis, it is well known that these users rarely read them. Nonetheless, these are binding contractual agreements. A recent study suggests that up to 98% of users do not fully read the terms of service before accepting them BIBREF0 . Additionally, they find that two of the top three factors users reported for not reading these documents were that they are perceived as too long (`information overload') and too complicated (`difficult to understand'). This can be seen in Table TABREF3 , where a section of the terms of service for a popular phone app includes a 78-word paragraph that can be distilled down to a 19-word summary.\nThe European Union's BIBREF1 , the United States' BIBREF2 , and New York State's BIBREF3 show that many levels of government have recognized the need to make legal information more accessible to non-legal communities. Additionally, due to recent social movements demanding accessible and transparent policies on the use of personal data on the internet BIBREF4 , multiple online communities have formed that are dedicated to manually annotating various unilateral contracts.\nWe propose the task of the automatic summarization of legal documents in plain English for a non-legal audience. We hope that such a technological advancement would enable a greater number of people to enter into everyday contracts with a better understanding of what they are agreeing to. Automatic summarization is often used to reduce information overload, especially in the news domain BIBREF5 . Summarization has been largely missing in the legal genre, with notable exceptions of judicial judgments BIBREF6 , BIBREF7 and case reports BIBREF8 , as well as information extraction on patents BIBREF9 , BIBREF10 . While some companies have conducted proprietary research in the summarization of contracts, this information sits behind a large pay-wall and is geared toward law professionals rather than the general public.\nIn an attempt to motivate advancement in this area, we have collected 446 sets of contract sections and corresponding reference summaries which can be used as a test set for such a task. We have compiled these sets from two websites dedicated to explaining complicated legal documents in plain English.\nRather than attempt to summarize an entire document, these sources summarize each document at the section level. In this way, the reader can reference the more detailed text if need be. The summaries in this dataset are reviewed for quality by the first author, who has 3 years of professional contract drafting experience.\nThe dataset we propose contains 446 sets of parallel text. We show the level of abstraction through the number of novel words in the reference summaries, which is significantly higher than the abstractive single-document summaries created for the shared tasks of the Document Understanding Conference (DUC) in 2002 BIBREF11 , a standard dataset used for single document news summarization. Additionally, we utilize several common readability metrics to show that there is an average of a 6 year reading level difference between the original documents and the reference summaries in our legal dataset.\nIn initial experimentation using this dataset, we employ popular unsupervised extractive summarization models such as TextRank BIBREF12 and Greedy KL BIBREF13 , as well as lead baselines. We show that such methods do not perform well on this dataset when compared to the same methods on DUC 2002. These results highlight the fact that this is a very challenging task. As there is not currently a dataset in this domain large enough for supervised methods, we suggest the use of methods developed for simplification and/or style transfer.\nIn this paper, we begin by discussing how this task relates to the current state of text summarization and similar tasks in Section SECREF2 . We then introduce the novel dataset and provide details on the level of abstraction, compression, and readability in Section SECREF3 . Next, we provide results and analysis on the performance of extractive summarization baselines on our data in Section SECREF5 . Finally, we discuss the potential for unsupervised systems in this genre in Section SECREF6 .\nWe show the level of abstraction through the number of novel words in the reference summaries, which is significantly higher than the abstractive single-document summaries created for the shared tasks of the Document Understanding Conference (DUC) in 2002, a standard dataset used for single document news summarization.",

The transfer learning among languages aimed to improve the accuracy when the models are initialized with utterances from a different language than the one used for the test set. Mel-scale spectrograms extracted from the transitions between voiced and unvoiced segments are used to train a CNN for each language. Then, the trained models are used to fine-tune a model to classify utterances in the remaining two languages.\nThe results indicate that the transfer learning among languages improved the accuracy of the models in up to 8% when a base model trained with Spanish utterances is used to fine-tune a model to classify PD German utterances. The results obtained after the transfer learning are also more balanced in terms of specificity-sensitivity and have a lower variance. In addition, the transfer learning among languages scheme was accurate to improve the accuracy in the target language only when the base model was robust enough. This was observed when the model trained with Spanish utterances was used to initialize the models for German and Czech languages.\nFurther experiments will include the development of more robust base models using hyper-parameter optimization strategies like those based on Bayesian optimization. In addition, the base models will be trained considering two of the languages instead of only one of them. The trained models will also be evaluated to classify the speech of PD patients in several stages of the disease based on the MDS-UPDRS-III score, or based on their dysarthria severity BIBREF20. Further experiments will also include transfer learning among diseases, for instance training a base model with utterances to classify PD, and use such a model to initialize another one to classify other neurological diseases such as Hungtinton's disease.\nThis study proposed the use of a transfer learning strategy based on fine-tuning to classify PD from speech in three different languages: Spanish, German, and Czech.",

        "answer": "Machine learning techniques based on structural and linguistic features of an article.",
        "evidence": "As observed by a recent article of Nature News BIBREF0 , “Wikipedia is among the most frequently visited websites in the world and one of the most popular places to tap into the world's scientific and medical information\". Despite the huge amount of consultations, open issues still threaten a fully confident fruition of the popular online open encyclopedia.\nA first issue relates to the reliability of the information available: since Wikipedia can be edited by anyone, regardless of their level of expertise, this tends to erode the average reputation of the sources, and, consequently, the trustworthiness of the contents posted by those sources. In an attempt to fix this shortcoming, Wikipedia has recently enlisted the help of scientists to actively support the editing on Wikipedia BIBREF0 . Furthermore, lack of control may lead to the publication of fake Wikipedia pages, which distort the information by inserting, e.g., promotional articles and promotional external links. Fighting vandalism is one of the main goals of the Wikimedia Foundation, the nonprofit organization that supports Wikipedia: machine learning techniques have been considered to offer a service to “judge whether an edit was made in good faith or not\" BIBREF1 . Nonetheless, in the past recent time, malicious organisations have acted disruptively with purposes of extortion - see, e.g., the recent news on the uncovering of a blackmail network of accounts, which threatened celebrities with the menace of inserting offending information on their Wikipedia pages.\nSecondly, articles may suffer from readability issues: achieving a syntactical accuracy that helps the reader with a fluid reading experience is —quite obviously— a property which articles should fulfill. Traditionally, the literature has widely adopted well known criteria, as the “Flesch-Kincaid\" measure\" BIBREF2 , to automatically assess readability in textual documents. More recently, new techniques have been proposed too, for assessing the readability of natural languages (see, e.g., BIBREF3 for the Italian use case, BIBREF4 for the Swedish one, BIBREF5 for English).\nIn this paper, we face the quest for quality assessment of a Wikipedia article, in an automatic way that comprehends not only readability and reliability criteria, but also additional parameters testifying completeness of information and coherence with the content one expects from an article dealing with specific topics, plus sufficient insights for the reader to elaborate further on some argument. The notion of data quality we deal with in the paper is coherent with the one suggested by recent contributions (see, e.g., BIBREF6 ), which points out like the quality of Web information is strictly connected to the scope for which one needs such information.\nOur intuition is that groups of articles related to a specific topic and falling within specific scopes are intrinsically different from other groups on different topics within different scopes. We approach the article evaluation through machine learning techniques. Such techniques are not new to be employed for automatic evaluation of articles quality. As an example, the work in BIBREF7 exploits classification techniques based on structural and linguistic features of an article. Here, we enrich that model with novel features that are domain-specific. As a running scenario, we focus on the Wikipedia medical portal. Indeed, facing the problems of information quality and ensuring high and correct levels of informativeness is even more demanding when health aspects are involved. Recent statistics report that Internet users are increasingly searching the Web for health information, by consulting search engines, social networks, and specialised health portals, like that of Wikipedia. As pointed out by the 2014 Eurobarometer survey on European citizens' digital health literacy, around six out of ten respondents have used the Internet to search for health-related information. This means that, although the trend in digital health literacy is growing, there is also a demand for a qualified source where people can ask and find medical information which, to an extent, can provide the same level of familiarity and guarantees as those given by a doctor or a health professional.\nWe anticipate here that leveraging new domain-specific features is in line with this demand of articles quality. Moreover, as the outcomes of our experiments show, they effectively improve the classification results in the hard task of multi-class assessment, especially for those classes that other automatic approaches worst classify. Remarkably, our proposal is general enough to be easily extended to other domains, in addition to the medical one.\nSection \"Dataset\" first describes the structure of the articles present in the medical portal. Then, it gives details on the real data used in the experiments, which are indeed articles extracted from the medical portal and labeled according to the manual assessment by the Wikimedia project. Section \"Baseline: the actionable model\" briefly presents the actionable model in BIBREF7 : we adopt it as the baseline for our analysis. In Section \"The medical domain model\" , we present the domain-specific, medical model we newly adopt in this paper as an extension of the baseline. The extended model includes features specifically extracted from the medical domain. One novel feature is based on the article textual content. Section \"Bio-medical entities\" presents the process which its extraction relies on, with a non trivial analysis of natural language and domain knowledge. Section \"Experiments and results\" presents experiments and results, with a comparison of the baseline model with the new one. In Section \"Related work\" , we survey related work in the area and in Section \"Conclusions\" we conclude the paper.\nWe approach the article evaluation through machine learning techniques.",

        "answer": "Different active learning strategies.",
        "evidence": "Micro-blogging social media platforms have become very popular in recent years. One of the most popular platforms is Twitter, which allows users to broadcast short texts (i.e., 140 characters initially, and 280 characters in a recent platform update) in real time with almost no restrictions on content. Twitter is a source of people’s attitudes, opinions, and thoughts toward the things that happen in their daily life. Twitter data are publicly accessible through Twitter application programming interface (API); and there are several tools to download and process these data. Twitter is being increasingly used as a valuable instrument for surveillance research and predictive analytics in many fields including epidemiology, psychology, and social sciences. For example, Bian et al. explored the relation between promotional information and laypeople’s discussion on Twitter by using topic modeling and sentiment analysis BIBREF0. Zhao et al. assessed the mental health signals among sexual and gender minorities using Twitter data BIBREF1. Twitter data can be used to study and predict population-level targets, such as disease incidence BIBREF2, political trends BIBREF3, earthquake detection BIBREF4, and crime perdition BIBREF5, and individual-level outcomes or life events, such as job loss BIBREF6, depression BIBREF7, and adverse events BIBREF8. Since tweets are unstructured textual data, natural language processing (NLP) and machine learning, especially deep learning nowadays, are often used for preprocessing and analytics. However, for many studiesBIBREF9, BIBREF10, BIBREF11, especially those that analyze individual-level targets, manual annotations of several thousands of tweets, often by experts, is needed to create gold-standard training datasets, to be fed to the NLP and machine learning tools for subsequent, reliable automated processing of millions of tweets. Manual annotation is obviously labor intense and time consuming.\nCrowdsourcing can scale up manual labor by distributing tasks to a large set of workers working in parallel instead of a single people working serially BIBREF12. Commercial platforms such as Amazon’s Mechanical Turk (MTurk, https://www.\nmturk.com/), make it easy to recruit a large crowd of people working remotely to perform time consuming manual tasks such as entity resolution BIBREF13, BIBREF14, image or sentiment annotation BIBREF15, BIBREF16. The annotation tasks published on MTurk can be done on a piecework basis and, given the very large pool of workers usually available (even by selecting a subset of those who have, say, a college degree), the tasks can be done almost immediately. However, any crowdsourcing service that solely relies on human workers will eventually be expensive when large datasets are needed, that is often the case when creating training datasets for NLP and deep learning tasks. Therefore, reducing the training dataset size (without losing performance and quality) would also improve efficiency while contain costs.\nQuery optimization techniques (e.g., active learning) can reduce the number of tweets that need to be labeled, while yielding comparable performance for the downstream machine learning tasks BIBREF17, BIBREF18, BIBREF19. Active learning algorithms have been widely applied in various areas including NLP BIBREF20 and image processing BIBREF21. In a pool-based active learning scenario, data samples for training a machine learning algorithm (e.g., a classifier for identifying job loss events) are drawn from a pool of unlabeled data according to some forms of informativeness measure (a.k.a. active learning strategies BIBREF22), and then the most informative instances are selected to be annotated. For a classification task, in essence, an active learning strategy should be able to pick the “best” samples to be labelled that will improve the classification performance the most.\nIn this study, we integrated active learning into a crowdsourcing pipeline for the classification of life events based on individual tweets. We analyzed the quality of crowdsourcing annotations and then experimented with different machine/deep learning classifiers combined with different active learning strategies to answer the following two research questions (RQs):\nRQ1. How does (1) the amount of time that a human worker spends on and (2) the number of workers assigned to each annotation task impact the quality of an-notation results?\nRQ2. Which active learning strategy is most efficient and cost-effective to build event classification models using Twitter data?\n-5pt\nWe analyzed the quality of crowdsourcing annotations and then experimented with different machine/deep learning classifiers combined with different active learning strategies to answer the following two research questions (RQs): RQ1.

        "answer": "Accuracy, F1, recall, and AUPR.",
        "evidence": "\nWe evaluate the performance of CRAFT in the task of forecasting conversational derailment in both the Wikipedia and CMV scenarios. To this end, for each of these datasets we pre-train the generative component on the unlabeled portion of the data and fine-tune it on the labeled training split (data size detailed in Section SECREF3).\nIn order to evaluate our sequential system against conversational-level ground truth, we need to aggregate comment level predictions. If any comment in the conversation triggers a positive prediction—i.e., $p_{\\text{event}}(c_{n+1})$ is greater than a threshold learned on the development split—then the respective conversation is predicted to derail. If this forecast is triggered in a conversation that actually derails, but before the derailment actually happens, then the conversation is counted as a true positive; otherwise it is a false positive. If no positive predictions are triggered for a conversation, but it actually derails then it counts as a false negative; if it does not derail then it is a true negative.\nFixed-length window baselines. We first seek to compare CRAFT to existing, fixed-length window approaches to forecasting. To this end, we implement two such baselines: Awry, which is the state-of-the-art method proposed in BIBREF9 based on pragmatic features in the first comment-reply pair, and BoW, a simple bag-of-words baseline that makes a prediction using TF-IDF weighted bag-of-words features extracted from the first comment-reply pair.\nOnline forecasting baselines. Next, we consider simpler approaches for making forecasts as the conversations happen (i.e., in an online fashion). First, we propose Cumulative BoW, a model that recomputes bag-of-words features on all comments seen thus far every time a new comment arrives. While this approach does exhibit the desired behavior of producing updated predictions for each new comment, it fails to account for relationships between comments.\nThis simple cumulative approach cannot be directly extended to models whose features are strictly based on a fixed number of comments, like Awry. An alternative is to use a sliding window: for a feature set based on a window of $W$ comments, upon each new comment we can extract features from a window containing that comment and the $W-1$ comments preceding it. We apply this to the Awry method and call this model Sliding Awry. For both these baselines, we aggregate comment-level predictions in the same way as in our main model.\nCRAFT ablations. Finally, we consider two modified versions of the CRAFT model in order to evaluate the impact of two of its key components: (1) the pre-training step, and (2) its ability to capture inter-comment dependencies through its hierarchical memory.\nTo evaluate the impact of pre-training, we train the prediction component of CRAFT on only the labeled training data, without first pre-training the encoder layers with the unlabeled data. We find that given the relatively small size of labeled data, this baseline fails to successfully learn, and ends up performing at the level of random guessing. This result underscores the need for the pre-training step that can make use of unlabeled data.\nTo evaluate the impact of the hierarchical memory, we implement a simplified version of CRAFT where the memory size of the context encoder is zero (CRAFT $-$ CE), thus effectively acting as if the pre-training component is a vanilla seq2seq model. In other words, this model cannot capture inter-comment dependencies, and instead at each step makes a prediction based only on the utterance encoding of the latest comment.\nResults. Table TABREF17 compares CRAFT to the baselines on the test splits (random baseline is 50%) and illustrates several key findings. First, we find that unsurprisingly, accounting for full conversational context is indeed helpful, with even the simple online baselines outperforming the fixed-window baselines. On both datasets, CRAFT outperforms all baselines (including the other online models) in terms of accuracy and F1. Furthermore, although it loses on precision (to CRAFT $-$ CE) and recall (to Cumulative BoW) individually on the Wikipedia data, CRAFT has the superior balance between the two, having both a visibly higher precision-recall curve and larger area under the curve (AUPR) than the baselines (Figure FIGREF20). This latter property is particularly useful in a practical setting, as it allows moderators to tune model performance to some desired precision without having to sacrifice as much in the way of recall (or vice versa) compared to the baselines and pre-existing solutions.\nTable 1 compares CRAFT to the baselines on the test splits (random baseline is 50%) and illustrates several key findings.

        "question": "List the components from this text into a comma separated list",
        "evidence": "Components\nBelow are some of the components and processes involved in the digital supply chain, in roughly sequential order, to bring raw content to a format available to a consumer via personal computer or set-top box:\n\nContent Provider\nThe content provider provides the actual content that will ultimately be consumed by the end-user. The content provider provides the content in a variety of formats - including film, tape, CD, DVD, hard disks and digital files.\n\nCapture\nIf the content provided by the content provider is not already in a digital format, it must first be converted to a digital format. In the case of film or tape, this is often called the “capture” process in which hardware will play back the original medium and “capture” its contents and convert it into a digital format. This captured file is often captured at the highest feasible quality as it is expected to undergo various processes that could degrade the quality. Therefore, the highest possible capture is always desired.\n\nCompression\nThe captured digital file is often extremely large, requiring a large amount of digital storage space and impossible to deliver to the consumer via broadband methods. Therefore, it must be compressed in a process called encoding or transcoding.\n\nIn this process, a codec is used to compress the captured digital file into a format which is small enough to be delivered to the end-user, usually via broadband methods. This encoding process entails consideration of many variables as to how the file is to be compressed. For audio, this usually consists of bit-rate and sample rate. Additional variables for video include resolution, frame rate and also has its own bit-rate that needs to be specified.\n\nThese variables are determined by how a particular file is to be consumed; download, streaming to a PC, streaming to a mobile device, etc.\n\nQuality, however, often becomes an issue at this stage and great care is taken to ensure the quality of the medium is of the highest possible quality for its intended deliver method. For example, a video encoded for streaming to mobile devices requires a much higher level of compression than would for a PC download, so the quality of the video will not be nearly as good.\n\nQuality Control\nQuality control is required to ensure that a file that has been encoded properly, with desired results and free of corruption. The degree to which a file is considered acceptable is based either on the discretion of the party charged with encoding the content, or a specific standard defined by the content owner for which the encoding party must comply.\n\nQuality control need not only take place at this juncture. Most companies dealing with the digital supply chain process will subject the media to scrutiny of the quality control process at various stages including: original capture, post-compression, post-ingest and post-publish, thus ensuring the media has not become corrupt or has not been degraded undesirably during any stage along the digital supply chain process.\n\nDigital Asset Management\nThe digital asset management system handles the metadata, content and their related assets such as album cover and movie poster art. It is often the digital asset management systems which also handles the publishing of the content itself to a digital storefront. Some digital asset management systems specifically built for the digital supply chain and the delivery of electronic media will track the progress of content as it goes through the digital supply chain. A good digital asset management system should also include reporting tools which can report back on the status of various aspects of the digital supply chain itself.\n\nMetadata Entry\nMetadata is the information that identifies and describes the contents of a medium. This information can include media-specific information such as: Title, artist(s), production company, seasonal/episodic description, original release date, etc. Metadata can also include business-related information such as: pricing and availability.\n\nDigital Rights Management\nAn important aspect of the digital supply chain is the process of encrypting the content so that it cannot be played back without the proper license which is often acquired via purchase of content or subscription. This reduces the possibility of media being pirated.\n\nIngest\nIngest is the stage in which the compressed file and metadata are put into the digital asset management system. It is not necessary for the metadata and the compressed media file to be ingested into the system at the same time, however, there will be a point in the process in which both have been ingested into the system and the metadata can reference the media file.\n\nContent Delivery Network\nWhen media files are ingested they are hosted and delivered from a content delivery network (CDN) capable of delivering the media to the end-user. The CDN should be able to support the expected number of consumers.\n\nMerchant/Storefront/Digital Retailer/Digital Service Provider\nThe content will ultimately display on a digital storefront where the consumer can view a catalog listing of the content and access the content via purchase, subscription or other method a merchant has elected to make the content available.",

Theoretically, it can be used as a general sound waveform time-frequency representation extractor to solve other acoustic tasks (although we did not test it in this paper).

In this paper, we have tested synperiodic filter bank generalizes well on both direction-of-arrival (DoA) task and sound source physical location ([x,y,z] coordinate) estimation task. It needs more test if the receiver configuration changes too much (i.e. rather than setting four microphones close with each other, but putting them far apart and at different corners)",

Nevertheless, the sound-based counterpart research has far lagged behind, despite all the fascinating properties sound signal exhibits. For example, sound is ubiquitous and insensitive to ambient illumination change, it has no field-of-view (FoV) constraints and is capable of circumventing physical barriers to perceive scene beyond line-of-sight. As a complementary sensing approach to vision, sound-based environment perception is of vital importance for acoustic scene understanding. A typical example is the sound source detection (answer where is it, when does it happen and what is it), given the recorded multi-channel sound waveforms.\nTo detect sound sources, we often deploy a spatially-configured microphone array to record an acoustic environment. Unlike camera or LiDAR scanner that directly captures RGB image or measures the range distance, sound waveform itself is a highly compressed one-dimensional points with high sampling rate, all sound source signals are compressed and mixed into the one-dimensional data format. Since different sound sources have different frequency property, it is essential convert waveform into time-frequency representation so that frequencies hidden in the waveform are explicitly split out.

Some other work correlates filter frequency response and filter length by initializing in mel-scale, but it is not scalable nor stable because the final initialization depends on the filter number. Moreover, all existing methods process raw waveform with one-scale filter bank, we argue that the one-scale sound perception easily leads to incomprehensive sound sources sensing, especially when sound sources have different frequency property or undergo various spatial motion.\nIn this paper, we first give comprehensive theoretical analysis on the filter bank impact on its extracted feature's time and frequency resolution. Based on the analysis, we propose a simple yet effective synperiodic filter bank construction strategy in which each filter's frequency response and length are correlated by rotating periodicity such that each filter's length is inversely proportional to its frequency resolution. The synperiodic filter bank thus internally maintains a better time-frequency resolution trade-off than traditional fixed-length filter bank.

        "question": "Given these paragraphs about Large language models, what is the prompting paradigm?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

Everyone has a role to play in getting us there and delivering for customers and growing the business is the most important thing most of us can do.\n\nA typical milestone on a high-growth journey is an IPO. But as companies get more serious about a potential IPO, there is a period where they stop talking about an IPO.  This might be counter-intuitive, but here’s why: there are important regulatory restrictions on what companies can and cannot say when it comes to company growth and plans as they approach becoming a public company. The consequences if you don’t follow those rules can be serious — the SEC can even delay our ability to go public if it determines we’ve improperly promoted an IPO. And that’s obviously a situation we want to avoid, should we be in a position to go public in the future.  \n\nAnd even language like this — \"should we be in a position to go public in the future\" — is vague.

Research by McAfee Labs discovered that \"Aurora\" was part of the file path on the attacker's machine that was included in two of the malware binaries McAfee said were associated with the attack. \"We believe the name was the internal name the attacker(s) gave to this operation,\" McAfee Chief Technology Officer George Kurtz said in a blog post.\n\nAccording to McAfee, the primary goal of the attack was to gain access to and potentially modify source code repositories at these high-tech, security, and defense contractor companies. \"[The SCMs] were wide open,\" says Alperovitch. \"No one ever thought about securing them, yet these were the crown jewels of most of these companies in many ways—much more valuable than any financial or personally identifiable data that they may have and spend so much time and effort protecting.\"\n\nHistory\n\nFlowers left outside Google China's headquarters after its announcement it might leave the country\nOn January 12, 2010, Google revealed on its blog that it had been the victim of a cyber attack. The company said the attack occurred in mid-December and originated from China. Google stated that over 20 other companies had been attacked; other sources have since cited that more than 34 organizations were targeted. As a result of the attack, Google said it was reviewing its business in China. On the same day, United States Secretary of State Hillary Clinton issued a brief statement condemning the attacks and requesting a response from China.\n\nOn January 13, 2010, the news agency All Headline News reported that the United States Congress plans to investigate Google's allegations that the Chinese government used the company's service to spy on human rights activists.\n\nIn Beijing, visitors left flowers outside of Google's office. However, these were later removed, with a Chinese security guard stating that this was an \"illegal flower tribute\". The Chinese government has yet to issue a formal response, although an anonymous official stated that China was seeking more information on Google's intentions.\n\nAttackers involved\nFurther information: Cyberwarfare by China\nTechnical evidence including IP addresses, domain names, malware signatures, and other factors, show Elderwood was behind the Operation Aurora attack. The \"Elderwood\" group was named by Symantec (after a source-code variable used by the attackers), and is referred to as the \"Beijing Group\" by Dell Secureworks. The group obtained some of Google's source code, as well as access to information about Chinese activists. Elderwood also targeted numerous other companies in the shipping, aeronautics, arms, energy, manufacturing, engineering, electronics, financial, and software sectors.\n\nThe \"APT\" designation for the Chinese threat actors responsible for attacking Google is APT17.\n\nElderwood specializes in attacking and infiltrating second-tier defense industry suppliers that make electronic or mechanical components for top defense companies. Those firms then become a cyber \"stepping stone\" to gain access to top-tier defense contractors. One attack procedure used by Elderwood is to infect legitimate websites frequented by employees of the target company – a so-called \"water hole\" attack, just as lions stake out a watering hole for their prey. Elderwood infects these less-secure sites with malware that downloads to a computer that clicks on the site. After that, the group searches inside the network to which the infected computer is connected, finding and then downloading executives' e-mails and critical documents on company plans, decisions, acquisitions, and product designs.\n\nAttack analysis\nIn its blog posting, Google stated that some of its intellectual property had been stolen. It suggested that the attackers were interested in accessing Gmail accounts of Chinese dissidents. According to the Financial Times, two accounts used by Ai Weiwei had been attacked, their contents read and copied; his bank accounts were investigated by state security agents who claimed he was under investigation for \"unspecified suspected crimes\". However, the attackers were only able to view details on two accounts and those details were limited to things such as the subject line and the accounts' creation date.\n\nSecurity experts immediately noted the sophistication of the attack. Two days after the attack became public, McAfee reported that the attackers had exploited purported zero-day vulnerabilities (unfixed and previously unknown to the target system developers) in Internet Explorer and dubbed the attack \"Operation Aurora\". A week after the report by McAfee, Microsoft issued a fix for the issue, and admitted that they had known about the security hole used since September. Additional vulnerabilities were found in Perforce, the source code revision software used by Google to manage their source code.\n\nVeriSign's iDefense Labs claimed that the attacks were perpetrated by \"agents of the Chinese state or proxies thereof\".\n\nAccording to a diplomatic cable from the U.S. Embassy in Beijing, a Chinese source reported that the Chinese Politburo directed the intrusion into Google's computer systems. The cable suggested that the attack was part of a coordinated campaign executed by \"government operatives, public security experts and Internet outlaws recruited by the Chinese government.\" The report suggested that it was part of an ongoing campaign in which attackers have \"broken into American government computers and those of Western allies, the Dalai Lama and American businesses since 2002.\" According to The Guardian's reporting on the leak, the attacks were \"orchestrated by a senior member of the Politburo who typed his own name into the global version of the search engine and found articles criticising him personally.\"\n\nOnce a victim's system was compromised, a backdoor connection that masqueraded as an SSL connection made connections to command and control servers running in Illinois, Texas, and Taiwan, including machines that were running under stolen Rackspace customer accounts. The victim's machine then began exploring the protected corporate intranet that it was a part of, searching for other vulnerable systems as well as sources of intellectual property, specifically the contents of source code repositories.\n\nThe attacks were thought to have definitively ended on Jan 4 when the command and control servers were taken down, although it is not known at this point whether or not the attackers intentionally shut them down. However, the attacks were still occurring as of February 2010.\n\nResponse and aftermath\nThe German, Australian, and French governments publicly issued warnings to users of Internet Explorer after the attack, advising them to use alternative browsers at least until a fix for the security hole was made. The German, Australian, and French governments considered all versions of Internet Explorer vulnerable or potentially vulnerable.\n\nIn an advisory on January 14, 2010, Microsoft said that attackers targeting Google and other U.S. companies used software that exploits a hole in Internet Explorer. The vulnerability affects Internet Explorer versions 6, 7, and 8 on Windows 7, Vista, Windows XP, Server 2003, Server 2008 R2, as well as IE 6 Service Pack 1 on Windows 2000 Service Pack 4.\n\nThe Internet Explorer exploit code used in the attack has been released into the public domain, and has been incorporated into the Metasploit Framework penetration testing tool. A copy of the exploit was uploaded to Wepawet, a service for detecting and analyzing web-based malware operated by the computer security group at the University of California, Santa Barbara. \"The public release of the exploit code increases the possibility of widespread attacks using the Internet Explorer vulnerability,\" said George Kurtz, CTO of McAfee, of the attack. \"The now public computer code may help cybercriminals craft attacks that use the vulnerability to compromise Windows systems.\"\n\nSecurity company Websense said it identified \"limited public use\" of the unpatched IE vulnerability in drive-by attacks against users who strayed onto malicious Web sites. According to Websense, the attack code it spotted is the same as the exploit that went public last week.[clarification needed] \"Internet Explorer users currently face a real and present danger due to the public disclosure of the vulnerability and release of attack code, increasing the possibility of widespread attacks,\" said George Kurtz, chief technology officer of McAfee, in a blog update. Confirming this speculation, Websense Security Labs identified additional sites using the exploit on January 19. According to reports from Ahnlab, the second URL was spread through the Instant Messenger network Misslee Messenger, a popular IM client in South Korea.\n\nResearchers have created attack code that exploits the vulnerability in Internet Explorer 7 (IE7) and IE8—even when Microsoft's recommended defensive measure (Data Execution Prevention (DEP)) is turned on.[dubious – discuss] According to Dino Dai Zovi, a security vulnerability researcher, \"even the newest IE8 isn't safe from attack if it's running on Windows XP Service Pack 2 (SP2) or earlier, or on Windows Vista RTM (release to manufacturing), the version Microsoft shipped in January 2007.\"\n\nMicrosoft admitted that the security hole used had been known to them since September. Work on an update was prioritized and on Thursday, January 21, 2010, Microsoft released a security patch aiming to counter this weakness, the published exploits based on it and a number of other privately reported vulnerabilities. They did not state if any of the latter had been used or published by exploiters or whether these had any particular relation to the Aurora operation, but the entire cumulative update was termed critical for most versions of Windows, including Windows 7.\n\nSecurity researchers continued to investigate the attacks. HBGary, a security firm, released a report in which they claimed to have found some significant markers that might help identify the code developer. The firm also said that the code was Chinese language based but could not be specifically tied to any government entity.\n\nOn February 19, 2010, a security expert investigating the cyber-attack on Google, has claimed that the people behind the attack were also responsible for the cyber-attacks made on several Fortune 100 companies in the past one and a half years. They have also tracked the attack back to its point of origin, which seems to be two Chinese schools, Shanghai Jiao Tong University and Lanxiang Vocational School. As highlighted by The New York Times, both of these schools have ties with the Chinese search engine Baidu, a rival of Google China. Both Lanxiang Vocational and Jiaotong University have denied the allegation.\n\nIn March 2010, Symantec, which was helping investigate the attack for Google, identified Shaoxing as the source of 21.3% of all (12 billion) malicious emails sent throughout the world.\n\nGoogle retrospective\nOn October 3, 2022, Google on YouTube released a six-episode series covering the events that occurred during Operation Aurora, with commentary from insiders who dealt with the attack, though the series primary focus was to reassure the Google-using public that measures are in place to counter hacking attempts.",

Relevant features proposed in the literature span from microblogging artifacts including hashtags, emoticons BIBREF0 , BIBREF1 , intensifiers like all-caps words and character repetitions BIBREF2 , sentiment-topic features BIBREF3 , to the inclusion of polarity lexicons.\nThe objective of the work presented in this paper is the creation of sentiment polarity lexicons. They are word lists or phrase lists with positive and negative sentiment labels. Sentiment lexicons allow to increase the feature space with more relevant and generalizing characteristics of the input. Unfortunately, creating sentiment lexicons requires human expertise, is time consuming, and often results in limited coverage when dealing with new domains.\nIn the literature, it has been proposed to extend existing lexicons without supervision BIBREF4 , BIBREF5 , or to automatically translate existing lexicons from resourceful languages with statistical machine translation (SMT) systems BIBREF6 . While the former requires seed lexicons, the later are very interesting because they can automate the process of generating sentiment lexicons without any human expertise. But automatically translating sentiment lexicons leads to two problems: (1) out-of-vocabulary words, such as mis-spellings, morphological variants and slang, cannot be translated, and (2) machine translation performance strongly depends on available training resources such as bi-texts.\nIn this paper, we propose to apply the method proposed in BIBREF7 for automatically mapping word embeddings across languages and use them to translate sentiment lexicons only given a small, general bilingual dictionary. After creating monolingual word embeddings in the source and target language, we train a linear transform on the bilingual dictionary and apply that transform to words for which we don't have a translation.\nWe perform experiments on 3-class polarity classification in tweets, and report results on four different languages: French, Italian, Spanish and German. Existing English sentiment lexicons are translated to the target languages through the proposed approach, given gs trained on the respective Wikipedia of each language. Then, a SVM-based classifier is fed with lexicon features, comparing machine translation with embedding transfer.\nAfter presenting related work in Section SECREF2 , the extraction of word gs and their mapping across languages are detailed in Section SECREF3 . The corpus on which experiments are carried out and the results of our experiments are presented in Section SECREF4 .

        "question": "How does the module perform?",
        "answer": "When applying the module to a sequence-to-sequence model with attention mechanism, it significantly increases its performance on both datasets.",
        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nWe show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets.",

As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never far from the Sun, either as morning star or evening star. Aside from the Sun and Moon, Venus is the brightest natural object in Earth's sky, capable of casting visible shadows on Earth in dark conditions and being visible to the naked eye in broad daylight.\n\nVenus is the second largest terrestrial object of the Solar System. It has a surface gravity slightly lower than on Earth and has a weak induced magnetosphere. The atmosphere of Venus consists mainly of carbon dioxide, and, at the planet’s surface, is the densest and hottest of the atmospheres of the four terrestrial planets. With an atmospheric pressure at the planet's surface of about 92 times the sea level pressure of Earth and a mean temperature of 737 K (464 °C; 867 °F), the carbon dioxide gas at Venus's surface is a supercritical fluid. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, making it the planet with the highest albedo in the Solar System. It may have had water oceans in the past, but after these evaporated the temperature rose under a runaway greenhouse effect. The possibility of life on Venus has long been a topic of speculation but research has not produced convincing evidence thus far.\n\nLike Mercury, Venus does not have any moons. Solar days on Venus, with a length of 117 Earth days, are just about half as long as its solar year, orbiting the Sun every 224.7 Earth days. This Venusian daylength is a product of it rotating against its orbital motion, halving its full sidereal rotation period of 243 Earth days, the longest of all the Solar System planets. Venus and Uranus are the only planets with such a retrograde rotation, making the Sun move in their skies from their western horizon to their eastern. The orbit of Venus around the Sun is the closest to Earth's orbit, bringing them closer than any other pair of planets. This occurs during inferior conjunction with a synodic period of 1.6 years.

        "evidence": "In recent years, the use of word representations, such as word2vec BIBREF0 , BIBREF1 and GloVe BIBREF2 , has become a key “secret sauce” for the success of many natural language processing (NLP), information retrieval (IR) and machine learning (ML) tasks. The empirical success of word embeddings raises an interesting research question: Beyond words, can we learn fixed-length distributed representations for pieces of texts? The texts can be of variable-length, ranging from paragraphs to documents. Such document representations play a vital role in a large number of downstream NLP/IR/ML applications, such as text clustering, sentiment analysis, and document retrieval, which treat each piece of text as an instance. Learning a good representation that captures the semantics of each document is thus essential for the success of such applications.\nIn this paper, we introduce KeyVec, a neural network model that learns densely distributed representations for documents of variable-length. In order to capture semantics, the document representations are trained and optimized in a way to recover key information of the documents. In particular, given a document, the KeyVec model constructs a fixed-length vector to be able to predict both salient sentences and key words in the document. In this way, KeyVec conquers the problem of prior embedding models which treat every word and every sentence equally, failing to identify the key information that a document conveys. As a result, the vectorial representations generated by KeyVec can naturally capture the topics of the documents, and thus should yield good performance in downstream tasks.\nWe evaluate our KeyVec on two text understanding tasks: document retrieval and document clustering. As shown in the experimental section SECREF5 , KeyVec yields generic document representations that perform better than state-of-the-art embedding models.\nIn particular, given a document, the KeyVec model constructs a fixed-length vector to be able to predict both salient sentences and key words in the document.",

        "evidence": "",
        "answer": "Singlish (a portmanteau of Singapore and English) (officially similar and related to Singaporean English) is an English-based creole language spoken in Singapore. Singlish arose out of a situation of prolonged language contact between speakers of many different languages in Singapore, including Hokkien, Malay, Teochew, Cantonese and Tamil.\n\nSinglish originated with the arrival of the British and the establishment of English-medium education in Singapore. Elements of English quickly filtered out of schools and onto the streets, resulting in the development of a pidgin language spoken by non-native speakers as a lingua franca used for communication between speakers of the many different languages used in Singapore. Singlish evolved mainly among the working classes who learned elements of English without formal schooling, mixing in elements of their native languages. After some time, this new pidgin language, now combined with substantial influences from Indian English, Peranakan, southern varieties of Chinese, Malay, and Tamil, became the primary language of the streets. As Singlish grew in popularity, children began to acquire Singlish as their native language, a process known as creolization. Through this process of creolization, Singlish became a fully-formed, stabilized and independent creole language, acquiring a more robust vocabulary and more complex grammar, with fixed phonology, syntax, morphology, and syntactic embedding.\n\nSinglish shares many linguistic similarities with Manglish or Bazaar Malay of Malaysia, although a few distinctions can be made, particularly in vocabulary. Manglish generally receives more Malay influence and Singlish more Chinese (Mandarin, Hokkien, etc.) influence. Initially, Singlish and Manglish were essentially the same dialect evolving from the British Malaya economy, born in the trading ports of Singapore, Malacca and Penang when Singapore and Peninsular Malaysia were for many purposes a de facto (from 1963 to 1965, de jure) single entity. Ever since the two countries separated, a divergence has been observed.\n\nLike all languages, Singlish and other creole languages show consistent internal logic and grammatical complexity. Due to its origins, Singlish shares many similarities with other English-based creole languages. As with many other creole languages, it is sometimes incorrectly perceived to be a \"broken\" form of the lexifier language - in this case, English. The uniqueness of Singlish has been studied by linguistics experts beyond Singapore.",

        "answer": "Academic paper rating is a relatively new task in NLP/AI, with the basic formulation being to automatically predict whether to accept or reject a paper.",
        "evidence": "A variety of approaches have been proposed for document quality assessment across different domains: Wikipedia article quality assessment, academic paper rating, content quality assessment in community question answering (cQA), and essay scoring. Among these approaches, some use hand-crafted features while others use neural networks to learn features from documents. For each domain, we first briefly describe feature-based approaches and then review neural network-based approaches. Wikipedia article quality assessment: Quality assessment of Wikipedia articles is a task that assigns a quality class label to a given Wikipedia article, mirroring the quality assessment process that the Wikipedia community carries out manually. Many approaches have been proposed that use features from the article itself, meta-data features (e.g., the editors, and Wikipedia article revision history), or a combination of the two. Article-internal features capture information such as whether an article is properly organized, with supporting evidence, and with appropriate terminology. For example, BIBREF3 use writing styles represented by binarized character trigram features to identify featured articles. BIBREF4 and BIBREF0 explore the number of headings, images, and references in the article. BIBREF5 use nine readability scores, such as the percentage of difficult words in the document, to measure the quality of the article. Meta-data features, which are indirect indicators of article quality, are usually extracted from revision history, and the interaction between editors and articles. For example, one heuristic that has been proposed is that higher-quality articles have more edits BIBREF6 , BIBREF7 . BIBREF8 use the percentage of registered editors and the total number of editors of an article. Article–editor dependencies have also been explored. For example, BIBREF9 use the authority of editors to measure the quality of Wikipedia articles, where the authority of editors is determined by the articles they edit. Deep learning approaches to predicting Wikipedia article quality have also been proposed. For example, BIBREF10 use a version of doc2vec BIBREF11 to represent articles, and feed the document embeddings into a four hidden layer neural network. BIBREF12 first obtain sentence representations by averaging words within a sentence, and then apply a biLSTM BIBREF13 to learn a document-level representation, which is combined with hand-crafted features as side information. BIBREF14 exploit two stacked biLSTMs to learn document representations.\nAcademic paper rating: Academic paper rating is a relatively new task in NLP/AI, with the basic formulation being to automatically predict whether to accept or reject a paper. BIBREF2 explore hand-crafted features, such as the length of the title, whether specific words (such as outperform, state-of-the-art, and novel) appear in the abstract, and an embedded representation of the abstract as input to different downstream learners, such as logistic regression, decision tree, and random forest. BIBREF15 exploit a modularized hierarchical convolutional neural network (CNN), where each paper section is treated as a module. For each paper section, they train an attention-based CNN, and an attentive pooling layer is applied to the concatenated representation of each section, which is then fed into a softmax layer.\nContent quality assessment in cQA: Automatic quality assessment in cQA is the task of determining whether an answer is of high quality, selected as the best answer, or ranked higher than other answers. To measure answer content quality in cQA, researchers have exploited various features from different sources, such as the answer content itself, the answerer's profile, interactions among users, and usage of the content. The most common feature used is the answer length BIBREF16 , BIBREF17 , with other features including: syntactic and semantic features, such as readability scores. BIBREF18 ; similarity between the question and the answer at lexical, syntactic, and semantic levels BIBREF18 , BIBREF19 , BIBREF20 ; or user data (e.g., a user's status points or the number of answers written by the user). There have also been approaches using neural networks. For example, BIBREF21 combine CNN-learned representations with hand-crafted features to predict answer quality. BIBREF22 use a 2-dimensional CNN to learn the semantic relevance of an answer to the question, and apply an LSTM to the answer sequence to model thread context. BIBREF23 and BIBREF24 model the problem similarly to machine translation quality estimation, treating answers as competing translation hypotheses and the question as the reference translation, and apply neural machine translation to the problem. Essay scoring: Automated essay scoring is the task of assigning a score to an essay, usually in the context of assessing the language ability of a language learner. The quality of an essay is affected by the following four primary dimensions: topic relevance, organization and coherence, word usage and sentence complexity, and grammar and mechanics. To measure whether an essay is relevant to its “prompt” (the description of the essay topic), lexical and semantic overlap is commonly used BIBREF25 , BIBREF26 . BIBREF27 explore word features, such as the number of verb formation errors, average word frequency, and average word length, to measure word usage and lexical complexity. BIBREF28 use sentence structure features to measure sentence variety. The effects of grammatical and mechanic errors on the quality of an essay are measured via word and part-of-speech $n$ -gram features and “mechanics” features BIBREF29 (e.g., spelling, capitalization, and punctuation), respectively. BIBREF30 , BIBREF31 , and BIBREF32 use an LSTM to obtain an essay representation, which is used as the basis for classification. Similarly, BIBREF33 utilize a CNN to obtain sentence representation and an LSTM to obtain essay representation, with an attention layer at both the sentence and essay levels.\nAcademic paper rating: Academic paper rating is a relatively new task in NLP/AI, with the basic formulation being to automatically predict whether to accept or reject a paper.",

        "question": "Dos the simplified version of CRAFT they used can capture inter-comment dependencies?",
        "answer": "No, it can only make a prediction based on the utterance encoding of the latest comment.",
        "evidence": "\nWe evaluate the performance of CRAFT in the task of forecasting conversational derailment in both the Wikipedia and CMV scenarios. To this end, for each of these datasets we pre-train the generative component on the unlabeled portion of the data and fine-tune it on the labeled training split (data size detailed in Section SECREF3).\nIn order to evaluate our sequential system against conversational-level ground truth, we need to aggregate comment level predictions. If any comment in the conversation triggers a positive prediction—i.e., $p_{\\text{event}}(c_{n+1})$ is greater than a threshold learned on the development split—then the respective conversation is predicted to derail. If this forecast is triggered in a conversation that actually derails, but before the derailment actually happens, then the conversation is counted as a true positive; otherwise it is a false positive. If no positive predictions are triggered for a conversation, but it actually derails then it counts as a false negative; if it does not derail then it is a true negative.\nFixed-length window baselines. We first seek to compare CRAFT to existing, fixed-length window approaches to forecasting. To this end, we implement two such baselines: Awry, which is the state-of-the-art method proposed in BIBREF9 based on pragmatic features in the first comment-reply pair, and BoW, a simple bag-of-words baseline that makes a prediction using TF-IDF weighted bag-of-words features extracted from the first comment-reply pair.\nOnline forecasting baselines. Next, we consider simpler approaches for making forecasts as the conversations happen (i.e., in an online fashion). First, we propose Cumulative BoW, a model that recomputes bag-of-words features on all comments seen thus far every time a new comment arrives. While this approach does exhibit the desired behavior of producing updated predictions for each new comment, it fails to account for relationships between comments.\nThis simple cumulative approach cannot be directly extended to models whose features are strictly based on a fixed number of comments, like Awry. An alternative is to use a sliding window: for a feature set based on a window of $W$ comments, upon each new comment we can extract features from a window containing that comment and the $W-1$ comments preceding it. We apply this to the Awry method and call this model Sliding Awry. For both these baselines, we aggregate comment-level predictions in the same way as in our main model.\nCRAFT ablations. Finally, we consider two modified versions of the CRAFT model in order to evaluate the impact of two of its key components: (1) the pre-training step, and (2) its ability to capture inter-comment dependencies through its hierarchical memory.\nTo evaluate the impact of pre-training, we train the prediction component of CRAFT on only the labeled training data, without first pre-training the encoder layers with the unlabeled data. We find that given the relatively small size of labeled data, this baseline fails to successfully learn, and ends up performing at the level of random guessing. This result underscores the need for the pre-training step that can make use of unlabeled data.\nTo evaluate the impact of the hierarchical memory, we implement a simplified version of CRAFT where the memory size of the context encoder is zero (CRAFT $-$ CE), thus effectively acting as if the pre-training component is a vanilla seq2seq model. In other words, this model cannot capture inter-comment dependencies, and instead at each step makes a prediction based only on the utterance encoding of the latest comment.\nResults. Table TABREF17 compares CRAFT to the baselines on the test splits (random baseline is 50%) and illustrates several key findings. First, we find that unsurprisingly, accounting for full conversational context is indeed helpful, with even the simple online baselines outperforming the fixed-window baselines. On both datasets, CRAFT outperforms all baselines (including the other online models) in terms of accuracy and F1. Furthermore, although it loses on precision (to CRAFT $-$ CE) and recall (to Cumulative BoW) individually on the Wikipedia data, CRAFT has the superior balance between the two, having both a visibly higher precision-recall curve and larger area under the curve (AUPR) than the baselines (Figure FIGREF20). This latter property is particularly useful in a practical setting, as it allows moderators to tune model performance to some desired precision without having to sacrifice as much in the way of recall (or vice versa) compared to the baselines and pre-existing solutions.\nTo evaluate the impact of the hierarchical memory, we implement a simplified version of CRAFT where the memory size of the context encoder is zero (CRAFT − CE), thus effectively acting as if the pre-training component is a vanilla seq2seq model. In other words, this model cannot capture inter-comment dependencies, and instead at each step makes a prediction based only on the utterance encoding of the latest comment.",

        "question": "From the above passage, provide some of the examples of black swan events. List the events in a bulleted list.",
        "evidence": "The phrase \"black swan\" derives from a Latin expression; its oldest known occurrence is from the 2nd-century Roman poet Juvenal's characterization in his Satire VI of something being \"rara avis in terris nigroque simillima cygno\" (\"a rare bird in the lands and very much like a black swan\").: 165  When the phrase was coined, the black swan was presumed not to exist. The importance of the metaphor lies in its analogy to the fragility of any system of thought. A set of conclusions is potentially undone once any of its fundamental postulates is disproved. In this case, the observation of a single black swan would be the undoing of the logic of any system of thought, as well as any reasoning that followed from that underlying logic.\n\nJuvenal's phrase was a common expression in 16th century London as a statement of impossibility. The London expression derives from the Old World presumption that all swans must be white because all historical records of swans reported that they had white feathers. In that context, a black swan was impossible or at least nonexistent.\n\nHowever, in 1697, Dutch explorers led by Willem de Vlamingh became the first Europeans to see black swans, in Western Australia.[citation needed] The term subsequently metamorphosed to connote the idea that a perceived impossibility might later be disproven. Taleb notes that in the 19th century, John Stuart Mill used the black swan logical fallacy as a new term to identify falsification.\n\nBlack swan events were discussed by Nassim Nicholas Taleb in his 2001 book Fooled By Randomness, which concerned financial events. His 2007 book The Black Swan extended the metaphor to events outside of financial markets. Taleb regards almost all major scientific discoveries, historical events, and artistic accomplishments as \"black swans\"—undirected and unpredicted. He gives the rise of the Internet, the personal computer, World War I, the dissolution of the Soviet Union, and the September 11, 2001 attacks as examples of black swan events.",

        "evidence": "Neural machine translation (NMT) BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 is a deep learning-based method for translation that has recently shown promising results as an alternative to statistical approaches. NMT systems directly model the probability of the next word in the target sentence simply by conditioning a recurrent neural network on the source sentence and previously generated target words.\nWhile both simple and surprisingly accurate, NMT systems typically need to have very high capacity in order to perform well: Sutskever2014 used a 4-layer LSTM with 1000 hidden units per layer (herein INLINEFORM0 ) and Zhou2016 obtained state-of-the-art results on English INLINEFORM1 French with a 16-layer LSTM with 512 units per layer. The sheer size of the models requires cutting-edge hardware for training and makes using the models on standard setups very challenging.\nThis issue of excessively large networks has been observed in several other domains, with much focus on fully-connected and convolutional networks for multi-class classification. Researchers have particularly noted that large networks seem to be necessary for training, but learn redundant representations in the process BIBREF6 . Therefore compressing deep models into smaller networks has been an active area of research. As deep learning systems obtain better results on NLP tasks, compression also becomes an important practical issue with applications such as running deep learning models for speech and translation locally on cell phones.\nExisting compression methods generally fall into two categories: (1) pruning and (2) knowledge distillation. Pruning methods BIBREF7 , BIBREF8 , BIBREF9 , zero-out weights or entire neurons based on an importance criterion: LeCun1990 use (a diagonal approximation to) the Hessian to identify weights whose removal minimally impacts the objective function, while Han2016 remove weights based on thresholding their absolute values. Knowledge distillation approaches BIBREF0 , BIBREF10 , BIBREF1 learn a smaller student network to mimic the original teacher network by minimizing the loss (typically INLINEFORM0 or cross-entropy) between the student and teacher output.\nIn this work, we investigate knowledge distillation in the context of neural machine translation. We note that NMT differs from previous work which has mainly explored non-recurrent models in the multi-class prediction setting. For NMT, while the model is trained on multi-class prediction at the word-level, it is tasked with predicting complete sequence outputs conditioned on previous decisions. With this difference in mind, we experiment with standard knowledge distillation for NMT and also propose two new versions of the approach that attempt to approximately match the sequence-level (as opposed to word-level) distribution of the teacher network. This sequence-level approximation leads to a simple training procedure wherein the student network is trained on a newly generated dataset that is the result of running beam search with the teacher network.\nWe run experiments to compress a large state-of-the-art INLINEFORM0 LSTM model, and find that with sequence-level knowledge distillation we are able to learn a INLINEFORM1 LSTM that roughly matches the performance of the full system. We see similar results compressing a INLINEFORM2 model down to INLINEFORM3 on a smaller data set. Furthermore, we observe that our proposed approach has other benefits, such as not requiring any beam search at test-time. As a result we are able to perform greedy decoding on the INLINEFORM4 model 10 times faster than beam search on the INLINEFORM5 model with comparable performance. Our student models can even be run efficiently on a standard smartphone. Finally, we apply weight pruning on top of the student network to obtain a model that has INLINEFORM6 fewer parameters than the original teacher model. We have released all the code for the models described in this paper.\nFurthermore, we observe that our proposed approach has other benefits, such as not requiring any beam search at test-time.",

        "question": "What professional tournaments did Liang win during his career?",
        "evidence": "Career\nAmateur years\nAs an amateur, Liang's major feats were as follows:\n\n2003 IBSF World Snooker Championship, men's division, quarter-finalist\n2004 IBSF World Snooker Championship, under-21 division, semi-finalist\n2005 International Open Series, under-21 division, no. 4 runner-up\nLiang built on the positive start to his snooker career, winning an individual silver medal and a team gold medal at the 2006 Asian Games.\n\n2004/2005\nLiang began his professional career during the 2004–05 snooker season playing on the Challenge Tour, which is the tier below the World Snooker Association Main Tour. He finished a mediocre 104th out of 168 competitors, having only accumulated 2150 points.\n\n2005/2006\nLiang received a wildcard nomination to the Main Tour despite not qualifying directly; this was because he won the 2005 IBSF World Under-21 Championship, and also because not all of the players that were eligible for the Main Tour took their places. In his first ranking tournament, the Grand Prix, he lost in the first qualifying round to Rory McLeod 2–5. He fared better in the next ranking event, the UK Championship, where he almost whitewashed Alfred Burden in the first qualifying round 9–1, but subsequently lost in the second qualifying round to Marcus Campbell by the narrowest of margins, 8–9.\n\nLiang qualified for his first ranking event at the Welsh Open, beating Sean Storey, Jamie Burnett and Rory McLeod to reach the main draw. He defeated Nigel Bond in the first round 5–0, but his run was halted when he lost to Graeme Dott 3–5.\n\nAt the Malta Cup, however, he lost in the first qualifying round to Paul Davies 3–5. At the China Open, he beat David McDonnell and Matthew Couch before losing against Adrian Gunnell 3–5 in the third qualifying round. He ended the season falling at the first hurdle at the World Championship, losing to Joe Delaney 5–10 in the first qualifying round. Liang ended his debut season on the professional tour ranked 78th, a position that would not guarantee a place in the following season's tour; however, he had finished inside the top 8 of the one year ranking list, which qualified him for a place on the main tour for the next season.\n\n2006/2007\nDuring the 2006–07 season, Liang reached at least the second round of qualifying in every ranking event. At the Northern Ireland Trophy, he beat Robert Stephen 5–0 before falling to David Gilbert 0–5 in qualifying. However, at the Grand Prix, Liang came top of his qualifying group, above more experienced players such as Gerard Greene and Barry Pinches. He finished fourth in his group at the round-robin stage, and although he did not progress to the next round, he did beat former world champion and world number one Stephen Hendry 3–0. At the UK Championship, he lost in the second round of qualifying to Jamie Burnett 7–9. In the following ranking event, the Malta Cup, he lost to Joe Jogia 3–5, again in the second round of qualifying. He qualified for the Welsh Open, his third ranking tournament, by beating Dene O'Kane, Joe Jogia and Mark Davis. He met Nigel Bond again in the last 48, this time losing only 3–5.\n\nAt the China Open, he continued his run of reaching the second round of qualifying in every ranking tournament, and beat Robert Stephen before losing to Finland's Robin Hull. At the World Championship, he beat Jeff Cundy before losing to Mike Dunn. After a modest season, he improved on his tour ranking by finishing in 66th place, just outside the top 64; and he topped the one year ranking list to ensure his place on the WSA Tour for next season.\n\n2007/2008\nLiang started the season by almost qualifying for the Shanghai Masters, however Nigel Bond beat him 5–3 in the last qualifying round, preventing him from appearing at his home tournament. At the Grand Prix, he could not repeat the success of last season and failed to qualify, finishing third on frame difference. He had more luck at the next tournament, the Northern Ireland Trophy, where he won through the qualifying rounds, beating Fraser Patrick, Joe Delaney and Rory McLeod on the way. He faced Gerard Greene in the last 48, but lost 2–5. He had less success at the UK Championship, losing in the second qualifying round to David Roe 2–9. He also failed to qualify for the Welsh Open, when he was dispatched in the last qualifying round by Andrew Norman 2–5. He fell at the first hurdle at his other home tournament, the China Open, losing in the first qualifying round to Steve Mifsud, who at the end of this season was ranked 54 places below Liang.\n\nAt the World Championship, Liang was the third Chinese player to qualify for the main draw, defeating Ben Woollaston, Rod Lawler, David Gilbert and Ian McCulloch in the qualifying rounds. He met Ken Doherty in the first round of the championship, and defeated him 10–5. Before the start of this match, he accidentally entered the arena at the same time as the match officials and had to hurry back; he subsequently received a warm ovation when he entered the arena for a second time after being introduced by MC Rob Walker. For every session thereafter, Walker introduced him as \"Should he stay or should he go... Liang Wenbo\", despite the rhyme occurring due to a mispronunciation of his name (\"bo\" is pronounced \"bwor\" in Chinese).\n\nLiang faced Northern Ireland's Joe Swail in the last 16 of the tournament. In a humorous incident, Liang fluked a red after scattering the balls, but failed to notice and went back to his seat. To the amusement of the spectators, Swail pointed out the mistake and the referee called Liang back to the table. In the 23rd frame, with a 12–10 lead, Liang prematurely celebrated winning the match after potting \"match ball\", only to then lose the frame due to a snooker; Swail came back to level the match at 12–12. In the final frame, Liang made early breaks of 34 and 30. He missed the final yellow but snookered Swail, leaving the cue ball in the jaws of the pocket. Liang followed up with a safety shot but Swail snookered him behind the blue; Liang failed to hit the yellow ball so Swail had the white replaced. In his second attempt, Liang hit the yellow directly and went on to win the frame 74–34, and thus the match, 13–12.\n\nThe incident in the last frame proved controversial as the referee replaced the cue ball in the wrong position, giving Liang a better sight of the yellow. At the time, Swail nodded his assent to the referee, but he complained in a post-match interview that Liang had behaved unprofessionally by not pointing out the referee's error. Commentators countered that Swail should have queried the placement of the ball before Liang took his shot, and that, given the tension of the situation, Liang could be forgiven for not thinking clearly.\n\nLiang faced eventual champion Ronnie O'Sullivan in the quarter-final, taking the first two frames with a break of 80 in the first, but O'Sullivan had levelled the match 4–4 by the end of the first session. O'Sullivan eased ahead in the second session and eventually won the match 13–7. Liang's run to the quarter-finals of the World Championship gained him 5000 ranking points, boosting his final ranking to number 40 in the world. This guaranteed that he would only have to win two qualifying matches to enter the main draw of the ranking tournaments the following season.\n\n2008/2009\nLiang began the new season by qualifying for the last 48 of the Northern Ireland Trophy. He then beat Steve Davis and Peter Ebdon to reach the last 16, where he lost to John Higgins 1–5. This result lifted him to a provisional career high of 26 in the world. He reached the main draw of the Grand Prix by winning two qualifying matches, but then succumbed to Ronnie O'Sullivan in the first round of the main draw. He then made a 147 and three other centuries (including two total clearances of 139) in a 5–1 victory over Martin Gould in the third qualifying round of the Bahrain Championship. However, he failed to qualify for the main draw, losing 2–5 to Michael Judge.\n\nFor the two Chinese events on this season's tour, Liang's two qualifying matches were held over until the venue stages. At the 2008 Shanghai Masters, he defeated Atthasit Mahitthi and Mark Allen to reach the main draw, but lost to Ryan Day 0–5 in the first round. Ironically, his second qualifying match for the Welsh Open was held over to ensure that his Welsh opponent Dominic Dale played at the main venue in Newport.\n\nLiang ended the season at the World Championship, after defeating Dave Harold 10–3 in the last qualifying round. He lost in the first round of the main draw 8–10 against Ding Junhui.\n\n2009/2010\nIn July 2009, Liang won his first professional title, the Beijing International Challenge, beating world number 2 Stephen Maguire 7–6 in the final. He made a further breakthrough in August when he reached the final of the Shanghai Masters, becoming only the second Chinese player, and the fourth Asian man, to reach a ranking final. He ultimately finished runner-up to Ronnie O'Sullivan.\n\nLiang qualified for the Grand Prix but was defeated 2–5 by Peter Ebdon in the first round, winning the first two frames and losing the last five in succession. Prior to this meeting, he had played Ebdon twice, winning 5–1 and 5–0. He reached the quarter-finals of the UK Championship after defeating Ryan Day 9–3, and Mark King 9–2. He went on to lose 2–9 to John Higgins in the quarter-finals. He failed to qualify for the Welsh Open and the China Open, as he lost 3–5 against Michael Judge and 2–5 against Andrew Higginson respectively.\n\nLiang qualified for the World Championships by defeating Rod Lawler 10–2. He was drawn against Ronnie O'Sullivan, but lost 7–10. After the quarter-finals of the event, it was clear that Liang would be ranked as number 16 the following season, the only new player entering the top 16 that season.\n\n2010/2011\nLiang began the season at the Wuxi Classic, where he lost in the first round 2–5 against Marco Fu. He participated at the Beijing International Challenge to defend his first professional title, but lost in the semi-finals 4–6 against eventual winner Tian Pengfei. Liang failed to qualify for the World Open, as he lost 1–3 against Andrew Higginson and lost his first round match at the Shanghai Masters 3–5 against Matthew Stevens. Having started the season inside the top 16, his results were not sufficient to maintain that position and he slipped out of the top 16. After this, he lost his qualifying matches in the five ranking tournaments.\n\nLiang also participated at the Players Tour Championship, his best performance coming at the third European event, where he reached the final, but lost 0–4 against Marcus Campbell. After 12 out of 12 events, he was ranked 14th in the Players Tour Championship Order of Merit. He lost his first round match at the Finals 1–4 against Ricky Walden.\n\n2011/2012\nLiang and Ding Junhui represented China at the World Cup and they won in the final 4–2 against the Northern Ireland team. During his match against Matthew Stevens in the first round of Australian Goldfields Open, Liang had a chance to make his second maximum break in his career, but he snookered himself on the yellow ball, and the break ended at 120. He won the match 5–4 to reach the second round, where he lost 4–5 against Ken Doherty. He also qualified for the Shanghai Masters, but lost in the first round 1–5 against Neil Robertson. After this, he was unable to qualify for the next two ranking events, as he lost 2–6 against Michael White at the UK Championship, and 3–5 against Liu Chuang at the German Masters.\n\nIn December 2011, Liang joined Romford-based snooker Academy and management team Grove Leisure. He beat David Gilbert and Rory McLeod, both 4–1, to reach the first round of the Welsh Open, where he faced John Higgins and was this time on the wrong end of a 4–1 scoreline. He narrowly missed out on a place in the World Open as he was defeated 4–5 by Mark King in the final round of qualifying. He also lost in qualifying for the China Open to the eventual winner of the event Peter Ebdon 0–5.\n\nLiang played in eleven of the twelve minor-ranking PTC events throughout the season, with a best finish in Event 10, where he lost in the quarter-finals to Dominic Dale. He also reached the last 16 in two other events to finish 38th in the PTC Order of Merit, outside of the top 24 who qualified for the Finals.\n\nHe qualified for the World Championship by defeating Marcus Campbell 10–9. He had led the match 8–2 and 9–5 before Campbell took it to 9–9, at which point the match was suspended to allow players on the other tables to begin their sessions. Liang subsequently won the decider with a 72 break and played defending champion Higgins again in the first round. He was involved in another final-frame decider, but was this time on the losing end as he bowed out of the tournament on the opening day, 9–10. He finished the season ranked world number 37.\n\n2012/2013\nLiang lost in qualifying for both the Wuxi Classic and the Shanghai Masters to Rod Lawler. He reached the venue stage of the Australian Goldfields Open by beating Thanawat Thirapongpaiboon, but lost 3–5 in the first round against Matthew Stevens. Liang beat Anthony McGill and Andrew Higginson to qualify for the UK Championship, where he saw a 4–3 lead in the first round against Barry Hawkins turn into a 4–6 defeat. Liang failed to qualify for the next two events, but won two matches to enter the main draw of both the Welsh Open and the China Open. In Wales he lost 2–4 to local favourite Stevens in the first round, and in his homeland of China he beat Lu Ning 5–1 in the wildcard round, before losing 3–5 to Stuart Bingham in the first round. Liang had a very consistent season in the Players Tour Championship series as he advanced to, but not past, the last 16 in five of the ten events. This saw him placed 27th on the PTC Order of Merit, one spot short of making the Finals. Liang's season ended when he was beaten 6–10 by Mark Davis in the final round of World Championship Qualifying. His end of year ranking was world number 32.\n\n2013/2014\n\nLiang Wenbo at the 2014 German Masters\nIn July 2013, Liang reached the final of the World Games but lost in the gold medal match 0–3 to Aditya Mehta. He had an excellent season in the Asian Tour events by reaching the semi-finals of the Zhangjiagang Open where he was defeated 1–4 by Michael Holt and at the Zhengzhou Open, where Liang won his first individual title on the World Snooker Tour. He beat Anthony McGill 4–3 in the semi-finals before whitewashing Lü Haotian 4–0 to claim the £10,000 first prize. In the full ranking events, Liang won five successive frames against defending world champion Ronnie O'Sullivan in the second round of the International Championship to triumph 6–4 which marked his first ever success over his opponent having lost in all four previous attempts. He then thrashed Mark Davis 6–1 to reach the quarter-finals of a ranking event for the first time in four years, where he lost 3–6 against Graeme Dott. Liang reached the last 16 of both the German Masters and Welsh Open, losing 2–5 to Mark Davis and 2–4 to Barry Hawkins respectively. A second final on the Asian Tour followed at the Dongguan Open where Stuart Bingham made four breaks above 50 to defeat him 4–1, but Liang still topped the Order of Merit to qualify for the Finals. There, he was beaten 2–4 by Yu Delu and Liang was defeated 7–10 by Martin Gould in the final round of World Championship qualifying.\n\n2014/2015\nLiang overcame Jamie Burnett 5–1 in the first round of the 2014 Wuxi Classic, and then inflicted the first defeat on Mark Selby since he won the World Championship, beating him 5–3. In the last 16, Liang was knocked out 2–5 by Joe Perry. He lost 3–5 against Robert Milkins in the opening round of the Australian Goldfields Open, and in the wildcard round of the Shanghai Masters 1–5 to Yan Bingtao. He failed to get past the last 64 of the next two ranking events, but won two matches to reach the German Masters, where he eliminated Li Hang 5–1 in the first round. He reached the quarter-finals by coming back from 3–4 down against Stuart Bingham to win 5–4 on the final pink. He repeated this form when he edged Ryan Day 5–4 to play in his second career ranking event semi-final, where he took four frames in a row to hold a narrow 4–3 advantage over Shaun Murphy, before losing three successive frames in a 4–6 defeat. Liang did not drop a single frame in seeing off Cao Xinlong and Gerard Greene at the Welsh Open, but was then the victim of a whitewash by John Higgins in the third round. At the inaugural World Grand Prix, he lost 3–4 to Graeme Dott in the second round. In the final round of World Championship qualifying, he lost the last three frames against compatriot Zhang Anda to be narrowly defeated 9–10.\n\n2015/2016\nLiang was heavily beaten 2–8 by Thepchaiya Un-Nooh in the final of the 2015 Six-red World Championship. In the third round of the UK Championship, he took advantage of a collapse from Judd Trump to win 6–4 after trailing 1–4. He then saw off Tom Ford 6–5, after which Ford accused Liang of \"boring him off the table\" with slow play. Liang responded by opening his quarter-final match against Marco Fu with three centuries and hung on to edge it 6–5, then came from 2–4 behind to reach the final by beating David Grace 6–4. It was the first final in the history of the event to feature two players from outside the United Kingdom; Liang lost the match 5–10 to eventual UK champion Neil Robertson. A week later, he progressed to the semi-finals of the Gibraltar Open, but was whitewashed 0–4 by Fu.\n\nLiang's UK final helped him break back into the top 16 in the world rankings to make his debut at the Masters, where he was knocked out 4–6 by John Higgins in the opening round. He was whitewashed 0–4 by Shaun Murphy in the quarter-finals of the World Grand Prix. After winning three matches to qualify for the World Championship, Liang lost 8–10 to Judd Trump after an earlier 7–3 lead.\n\n2016/2017\nIn the first round of the Shanghai Masters, Liang was narrowly beaten 4–5 by Ronnie O'Sullivan. He won five matches at the English Open, which included a 4–3 second round victory over Shaun Murphy, to reach the semi-finals. From 3–4 down, Liang made breaks of 134 and 138 and Stuart Bingham made a 116 to lock the score at 5–5. Liang took the decider and then ended Judd Trump's 14-match winning streak in the final to win his maiden ranking title 9–6. He became the second player from mainland China to win a ranking event and thanked O'Sullivan (with whom he practises daily) for his help. The win also gave him entry to his first Champion of Champions where he lost 0–4 in the opening round to Mark Selby.\n\nIn the Scottish Open, Liang reached the quarter-finals, where he lost to Yu Delu 4–5. In the Masters, he missed the final black, which would have seen him eliminate O'Sullivan 6–4 in the opening round of the Masters, instead going on to lose 5–6. A 4–0 thrashing of Dominic Dale and a pair of 4–3 victories over Mark Allen and Joe Perry moved Liang into the semi-finals of the World Grand Prix, where he was defeated 1–6 by Barry Hawkins. In the second round of the World Championship, Liang trailed Ding Junhui 2–6 after the first session and 7–9 after the second. He then won a trio of frames to take the lead in the match for the first time and would have been 12–11 ahead, one frame away from reaching the quarter-finals for the second time, but instead lost 12–13. After the event, his end-of-season ranking rose to 11, which was a career-high.\n\n2017/2018\nThough Liang had a decent campaign this season, he was unable to reach the same height as previous season. In his first round match against Ronnie O'Sullivan at the Masters. In a best -of-11 match, Liang led 5-4 up and only needed the final black in the 10th frame to guarantee his place in the quarter final; however, he missed the relatively easy black, and subsequently lost the frame and eventually the match. In his match against Rod Lawler in the World Championship Qualifying round, Liang made a 147 in the 10th frame, the third 147 in his career. But interestingly, he also had a chance to make another 147 in the 12th frame, but he missed the tricky final black.\n\n2018/2019\nLiang had a somewhat of a down season in the 2018/19 campaign. His best results came in the European Masters, China Open, and China Championship, in which he advanced to the third round. Liang only earned a total of 78,500 ranking points, which was 141,100 points shy from his best season in 2016/2017.\n\n2019/2020\nThis season Liang saw some improvement in this form. His best result came in the UK Championship, in which he defeated Dominic Dale, David Grace, Eden Sharav, and Li Hang, before losing to the eventual champion Ding Junhui in the quarter final. Liang also reached the quarter final of the Gibraltar Open, losing 4–1 to Judd Trump.",

        "answer": "It is created with 5,000 Reddit posts annotated with levels of dogmatism.",
        "evidence": "“I'm supposed to trust the opinion of a MS minion? The people that produced Windows ME, Vista and 8? They don't even understand people, yet they think they can predict the behavior of new, self-guiding AI?” –anonymous\n“I think an AI would make it easier for Patients to confide their information because by nature, a robot cannot judge them. Win-win? :D”' –anonymous\nDogmatism describes the tendency to lay down opinions as incontrovertibly true, without respect for conflicting evidence or the opinions of others BIBREF0 . Which user is more dogmatic in the examples above? This question is simple for humans. Phrases like “they think” and “they don't even understand,” suggest an intractability of opinion, while “I think” and “win-win?” suggest the opposite. Can we train computers to draw similar distinctions? Work in psychology has called out many aspects of dogmatism that can be modeled computationally via natural language, such as over-confidence and strong emotions BIBREF1 .\nWe present a statistical model of dogmatism that addresses two complementary goals. First, we validate psychological theories by examining the predictive power of feature sets that guide the model's predictions. For example, do linguistic signals of certainty help to predict a post is dogmatic, as theory would suggest? Second, we apply our model to answer four questions:\nR1: What kinds of topics (e.g., guns, LGBT) attract the highest levels of dogmatism?\nR2: How do dogmatic beliefs cluster?\nR3: How does dogmatism influence a conversation on social media? R4: How do other user behaviors (e.g., frequency and breadth of posts) relate to dogmatism?\nWe train a predictive model to classify dogmatic posts from Reddit, one of the most popular discussion communities on the web. Posts on Reddit capture discussion and debate across a diverse set of domains and topics – users talk about everything from climate change and abortion, to world news and relationship advice, to the future of artificial intelligence. As a prerequisite to training our model, we have created a corpus of 5,000 Reddit posts annotated with levels of dogmatism, which we are releasing to share with other researchers.\nUsing the model, we operationalize key domain-independent aspects of psychological theories of dogmatism drawn from the literature. We find these features have predictive power that largely supports the underlying theory. For example, posts that use less confident language tend to be less dogmatic. We also discover evidence for new attributes of dogmatism. For example, dogmatic posts tend not to verbalize cognition, through terms such as “I think,” “possibly,” or “might be.”\nOur model is trained on only 5,000 annotated posts, but once trained, we use it to analyze millions of other Reddit posts to answer our research questions. We find a diverse set of topics are colored by dogmatic language (e.g., people are dogmatic about religion, but also about LGBT issues). Further, we find some evidence for dogmatism as a deeper personality trait – people who are strongly dogmatic about one topic are more likely to express dogmatic views about others as well. Finally, in conversation, we discover that one user's dogmatism tends to bring out dogmatism in their conversational partner, forming a vicious cycle.\nAs a prerequisite to training our model, we have created a corpus of 5,000 Reddit posts annotated with levels of dogmatism, which we are releas_x005f_x001f_ing to share with other researchers.",

        "answer": "Venezuela (/ˌvɛnəˈzweɪlə/; American Spanish: [beneˈswela] (listen)), officially the Bolivarian Republic of Venezuela (Spanish: República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It has a territorial extension of 916,445 km2 (353,841 sq mi), and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas.\n\nThe continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. The Venezuelan government maintains a claim against Guyana to Guayana Esequiba. Venezuela is a federal presidential republic consisting of 23 states, the Capital District and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the north and in the capital.\n\nThe territory of Venezuela was colonized by Spain in 1522 amid resistance from indigenous peoples. In 1811, it became one of the first Spanish-American territories to declare independence from the Spanish and to form part, as a department, of the first federal Republic of Colombia (historiographically known as Gran Colombia). It separated as a full sovereign country in 1830. During the 19th century, Venezuela suffered political turmoil and autocracy, remaining dominated by regional military dictators until the mid-20th century. Since 1958, the country has had a series of democratic governments, as an exception where most of the region was ruled by military dictatorships, and the period was characterized by economic prosperity. Economic shocks in the 1980s and 1990s led to major political crises and widespread social unrest, including the deadly Caracazo riots of 1989, two attempted coups in 1992, and the impeachment of a President for embezzlement of public funds charges in 1993. The collapse in confidence in the existing parties saw the 1998 Venezuelan presidential election, the catalyst for the Bolivarian Revolution, which began with a 1999 Constituent Assembly, where a new Constitution of Venezuela was imposed. The government's populist social welfare policies were bolstered by soaring oil prices, temporarily increasing social spending, and reducing economic inequality and poverty in the early years of the regime. However, poverty began to increase in the 2010s. The 2013 Venezuelan presidential election was widely disputed leading to widespread protest, which triggered another nationwide crisis that continues to this day. Venezuela has experienced democratic backsliding, shifting into an authoritarian state. It ranks low in international measurements of freedom of the press and civil liberties and has high levels of perceived corruption.\n\nVenezuela is a developing country and ranks 113th on the Human Development Index. It has the world's largest known oil reserves and has been one of the world's leading exporters of oil. Previously, the country was an underdeveloped exporter of agricultural commodities such as coffee and cocoa, but oil quickly came to dominate exports and government revenues. The excesses and poor policies of the incumbent government led to the collapse of Venezuela's entire economy. The country struggles with record hyperinflation, shortages of basic goods, unemployment, poverty, disease, high child mortality, malnutrition, severe crime and corruption. These factors have precipitated the Venezuelan migrant crisis where more than three million people have fled the country. By 2017, Venezuela was declared to be in default regarding debt payments by credit rating agencies. The crisis in Venezuela has contributed to a rapidly deteriorating human rights situation, including increased abuses such as torture, arbitrary imprisonment, extrajudicial killings and attacks on human rights advocates. Venezuela is a charter member of the UN, Organization of American States (OAS), Union of South American Nations (UNASUR), ALBA, Mercosur, Latin American Integration Association (LAIA) and Organization of Ibero-American States (OEI).",

        "question": "Where is Galapogas Island located? What is the area of Galapogas? How many islands are there in total? When was the first island formed? What are few Volcanos in Galapogas?",
        "evidence": "The islands are located in the eastern Pacific Ocean, 973 km (605 mi) off the west coast of South America. The majority of islands are also more broadly part of the South Pacific. The closest land mass is that of mainland Ecuador, the country to which they belong, 926 km (500 nmi) to the east.\n\n\nOrthographic projection centered over the Galápagos.\n\nSchool of scalloped hammerheads, Wolf Island, Galápagos Islands.\n\nGrapsus grapsus on the rocks.\n\nSatellite photo of the Galápagos islands overlaid with the names of the visible main islands.\n\nIsabela seen from Spot Satellite.\n\nWaved albatrosses on Española.\n\nGalápagos marine iguana.\n\nMain Street on San Cristóbal Island.\nAn animated tour of the Galápagos.\nNASA oceanographer Gene Carl Feldman reflects on his unique perspective on this region.\nThe islands are found at the coordinates 1°40'N–1°36'S, 89°16'–92°01'W. Straddling the equator, islands in the chain are located in both the northern and southern hemispheres, with Volcán Wolf and Volcán Ecuador on Isla Isabela being directly on the equator. Española Island, the southernmost islet of the archipelago, and Darwin Island, the northernmost one, are spread out over a distance of 220 km (137 mi). The International Hydrographic Organization (IHO) considers them wholly within the South Pacific Ocean, however The Galápagos Archipelago consists of 7,880 km2 (3,040 sq mi) of land spread over 45,000 km2 (17,000 sq mi) of ocean. The largest of the islands, Isabela, measures 2,250 square miles (5,800 km2)and makes up close to three-quarters of the total land area of the Galápagos. Volcán Wolf on Isabela is the highest point, with an elevation of 1,707 m (5,600 ft) above sea level.\n\nThe group consists of 18 main islands, 3 smaller islands, and 107 rocks and islets. The islands are located at the Galapagos Triple Junction. The archipelago is located on the Nazca Plate (a tectonic plate), which is moving east/southeast, diving under the South American Plate at a rate of about 2.5 inches (6.4 cm) per year.It is also atop the Galápagos hotspot, a place where the Earth's crust is being melted from below by a mantle plume, creating volcanoes. The first islands formed here at least 8 million and possibly up to 90 million years ago.\n\nWhile the older islands have disappeared below the sea as they moved away from the mantle plume, the youngest islands, Isabela and Fernandina, are still being formed. In April 2009, lava from the volcanic island Fernandina started flowing both towards the island's shoreline and into the center caldera.\n\nIn late June 2018, Sierra Negra, one of five volcanoes on Isabela and one of the most active in the Galapagos archipelago, began erupting for the first time since 2005. Lava flows made their way to the coastline, prompting the evacuation of about fifty nearby residents and restricting tourist access.",

Players take control of Aloy, a hunter who ventures through a post-apocalyptic land ruled by robotic creatures. Aloy can kill enemies in a variety of ways – shooting them with arrows, setting traps such as tripwires using the Tripcaster, using explosives, and a spear. Machine components, including electricity and the metal they are composed of, are vital to Aloy's survival; she can loot their remains for crafting resources. Ammo, resource satchels, pouches, quivers, resistance, antidotes, health potions, and traps can all be crafted. Weapons have modification slots for dealing more damage. Aloy wears a Focus, a small head piece that scans machines to determine their susceptibilities, identify their location, their level, and the nature of loot they will drop. One machine, the Stalker, can enable cloaking technology to avert the gaze of Aloy's Focus scan. Machines attack with defensive and offensive measures, and in either case react to a perceived threat by charging at it with brute force or projectiles. Exhibiting the behaviour of wild animals, some machines are inclined to move in herds, and others, with the ability to fly, do so in flocks. Unless hacked with the Override Tool, or sufficiently hit with corruption arrows, machines do not exert aggressive force against each other.

Considered one of the most significant authors of the 20th century, particularly in the Spanish language, he was awarded the 1972 Neustadt International Prize for Literature and the 1982 Nobel Prize in Literature. He pursued a self-directed education that resulted in leaving law school for a career in journalism. From early on he showed no inhibitions in his criticism of Colombian and foreign politics. In 1958, he married Mercedes Barcha Pardo; they had two sons, Rodrigo and Gonzalo.\n\nGarcía Márquez started as a journalist and wrote many acclaimed non-fiction works and short stories, but is best known for his novels, such as One Hundred Years of Solitude (1967), Chronicle of a Death Foretold (1981), and Love in the Time of Cholera (1985). His works have achieved significant critical acclaim and widespread commercial success, most notably for popularizing a literary style known as magic realism, which uses magical elements and events in otherwise ordinary and realistic situations. Some of his works are set in the fictional village of Macondo (mainly inspired by his birthplace, Aracataca), and most of them explore the theme of solitude.

        "answer": "There are many elements to a good cocktail, and these can often be modified to fit individual tastes. In general, a cocktail contains a base spirit, flavors from bitters or amaros, and something to sweeten. There are optional ingredients to add as well, like fruit, juice, or herbs. \n\nThe amount of each ingredient can vary the flavor significantly, so it is important to understand the impact of each ingredient. For example, very strong flavors like bitters or absinthe should be used in very small quantities. Sometimes even a rinse in the cocktail glass or spritz on the top of the prepared cocktail is enough to add the desired amount of flavor.\n\nA good cocktail comes about from a balance in flavors that build and develop off one another. The deep wooden flavor in whiskey is brightened by the citrus twist of an old fashioned. The sweetness from pineapple juice is deepened by the bitterness of campari in a jungle bird. The bitterness of ginger syrup is balanced with the tartness of lemon juice in a penicillin. \n\nMany newer cocktails are spins off a classic. Each builds off a flavor profile and modifies some of the more subtle flavors therein. If one wants to experiment with creating a new cocktail, starting with a classic favorite could be a good place to start. \n\nIt is also possible to create the same balanced flavors without the use of spirits (or with the use of alcohol free spirits).",

        "answer": "Central processing unit (CPU) and a graphics processing unit (GPU) have very different roles. The CPU can have multiple processing cores and is commonly referred to as the brain of the computer. It is essential to all modern computing systems as it executes the commands and processes needed for your computer and operating system. The CPU is also important in determining how fast programs can run, from surfing the web to building spreadsheets. The GPU is a processor that is made up of many smaller and more specialized cores. By working together, the cores deliver massive performance when a processing task can be divided up and processed across many cores.\n\nWhile CPUs and GPUs have a lot in common - Both are critical computing engines. Both are silicon-based microprocessors. And both handle data - they do have different architectures and are built for different purposes.\n\nThe CPU is suited to a wide variety of workloads, especially those for which latency or per-core performance are important. A powerful execution engine, the CPU focuses its smaller number of cores on individual tasks and on getting things done quickly. This makes it uniquely well equipped for jobs ranging from serial computing to running databases.\n\nGPUs began as specialized ASICs developed to accelerate specific 3D rendering tasks. Over time, these fixed-function engines became more programmable and more flexible. While graphics and the increasingly lifelike visuals of today’s top games remain their principal function, GPUs have evolved to become more general-purpose parallel processors as well, handling a growing range of applications.",

        "evidence": "Inspired by BIBREF6 , the first embedding layer is a vector representing each target word INLINEFORM0 obtained by concatenating the embedding of that word with those of the aligned words INLINEFORM1 in the source. If a target word is aligned to multiple source words, we average the embedding of all the source words, and concatenate the target word embedding with its average source embedding. The immediate left and right contexts for source and target words are also concatenated, enriching the local context information of the embedding of target word INLINEFORM2 . Thus, the embedding of target word INLINEFORM3 , denoted as INLINEFORM4 , is a INLINEFORM5 dimensional vector, where INLINEFORM6 is the dimension of the word embeddings. The source and target words use the same embedding parameters, and thus identical words in both languages, such as digits and proper nouns, have the same embedding vectors. This allows the model to easily identify identical words in both languages. Similarly, the POS tags in both languages share the same embedding parameters. Table TABREF4 shows the statistics of the set of POS tags over all language pairs.\nThe source and target words use the same embedding parameters, and thus identical words in both languages, such as digits and proper nouns, have the same embedding vectors.

From the Tropics to the Snow marked a significant break with the traditional style of such features, and is noted for its subversive and satirical approach to its subject.\n\nRather than using the stilted, authoritative single-voice narration that was typical of such 'promotion documentaries' at the time, Mason and Lee opted for a strikingly reflexive approach, using a lively (and frequently tongue-in-cheek) multi-voice narration, which is introduced through the dramatic device of a production planning meeting between the film's Producer-in-Chief (Alexander Archdale), the director (Alastair Smart) and the screenwriter (Livermore). This allowed the film to become an ironic critique of itself, humorously examining the mechanics of \"documentary\" film construction, and the competing pressures and choices that faced filmmakers when creating such films. It also gently parodied Lee and Mason's own situation as \"young turks\" charged with turning out what were in essence \"production-line\" propaganda films for a hidebound government department.\n\nThe film co-won the Australian Film Institute's Gold Medal for Best Film in 1965.",

        "evidence": "We have presented a method for quantifying the similarity and relatedness between two terms that integrates pair–wise similarity scores into second–order vectors. The goal of this approach is two–fold. First, we restrict the context used by the vector measure to words that exist in the biomedical domain, and second, we apply larger weights to those word pairs that are more similar to each other. Our hypothesis was that this combination would reduce the amount of noise in the vectors and therefore increase their correlation with human judgments. We evaluated our method on datasets that have been manually annotated for relatedness and similarity and found evidence to support this hypothesis. In particular we discovered that guiding the creation of a second–order context vector by selecting term pairs from biomedical text based on their semantic similarity led to improved levels of correlation with human judgment.\nWe also explored using a threshold cutoff to include only those term pairs that obtained a sufficiently large level of similarity. We found that eliminating less similar pairs improved the overall results (to a point). In the future, we plan to explore metrics to automatically determine the threshold cutoff appropriate for a given dataset and measure. We also plan to explore additional features that can be integrated with a second–order vector measure that will reduce the noise but still provide sufficient information to quantify relatedness. We are particularly interested in approaches that learn word, phrase, and sentence embeddings from structured corpora such as literature BIBREF23 and dictionary entries BIBREF24 . Such embeddings could be integrated into a second–order vector or be used on their own.\nFinally, we compared our proposed method to other distributional approaches, focusing on those that used word embeddings. Our results showed that integrating semantic similarity measures into second–order co–occurrence vectors obtains the same or higher correlation with human judgments as do various different word embedding approaches. However, a direct comparison was not possible due to variations in the subsets of the UMNSRS evaluation dataset used. In the future, we would not only like to conduct a direct comparison but also explore integrating semantic similarity into various kinds of word embeddings by training on pair–wise values of semantic similarity as well as co–occurrence statistics.\nOur hypothesis was that this combination would reduce the amount of noise in the vectors and therefore increase their correlation with human judgments.",

Nissan Leaf is a good car on paper. However, consumers were unwilling to switch because of the status quo bias.

It relied on the traditional auto-sales process, which is already cumbersome, and consumers view it as a haggle.\n\nOn the other hand, Tesla came with 10X improvements overall in customer experience, drivability, charging stations, integrated hardware and software (over-the-wire updates), and direct to consumer sales model with zero advertising.

        "evidence": "The goal of multi-document summarization (MDS) is to automatically generate a brief, well-organized summary for a topic which describes an event with a set of documents from different sources. BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . In the typical setting of MDS, the input is a set of news documents about the same topic. The output summary is a piece of short text document containing several sentences, generated only based on the input original documents.\nWith the development of social media and mobile equipments, more and more user generated content is available. Figure FIGREF2 is a snapshot of reader comments under the news report “The most important announcements from Google's big developers' conference”. The content of the original news report talks about some new products based on AI techniques. The news report generally conveys an enthusiastic tone. However, while some readers share similar enthusiasms, some others express their worries about new products and technologies and these comments can also reflect their interests which may not be very salient in the original news reports. Unfortunately, existing MDS approaches cannot handle this issue. We investigate this problem known as reader-aware multi-document summarization (RA-MDS). Under the RA-MDS setting, one should jointly consider news documents and reader comments when generating the summaries.\nOne challenge of the RA-MDS problem is how to conduct salience estimation by jointly considering the focus of news reports and the reader interests revealed by comments. Meanwhile, the model should be insensitive to the availability of diverse aspects of reader comments. Another challenge is that reader comments are very noisy, not fully grammatical and often expressed in informal expressions. Some previous works explore the effect of comments or social contexts in single document summarization such as blog summarization BIBREF7 , BIBREF8 . However, the problem setting of RA-MDS is more challenging because the considered comments are about an event which is described by multiple documents spanning a time period. Another challenge is that reader comments are very diverse and noisy. Recently, BIBREF9 employed a sparse coding based framework for RA-MDS jointly considering news documents and reader comments via an unsupervised data reconstruction strategy. However, they only used the bag-of-words method to represent texts, which cannot capture the complex relationship between documents and comments.\nRecently, BIBREF6 proposed a sentence salience estimation framework known as VAESum based on a neural generative model called Variational Auto-Encoders (VAEs) BIBREF10 , BIBREF11 . During our investigation, we find that the Gaussian based VAEs have a strong ability to capture the salience information and filter the noise from texts. Intuitively, if we feed both the news sentences and the comment sentences into the VAEs, commonly existed latent aspect information from both of them will be enhanced and become salient. Inspired by this consideration, to address the sentence salience estimation problem for RA-MDS by jointly considering news documents and reader comments, we extend the VAESum framework by training the news sentence latent model and the comment sentence latent model simultaneously by sharing the neural parameters. After estimating the sentence salience, we employ a phrase based compressive unified optimization framework to generate a final summary.\nThere is a lack of high-quality dataset suitable for RA-MDS. Existing datasets from DUC and TAC are not appropriate. Therefore, we introduce a new dataset for RA-MDS. We employed some experts to conduct the tasks of data collection, aspect annotation, and summary writing as well as scrutinizing. To our best knowledge, this is the first dataset for RA-MDS.\nOur contributions are as follows: (1) We investigate the RA-MDS problem and introduce a new dataset for the problem of RA-MDS. To our best knowledge, it is the first dataset for RA-MDS. (2) To tackle the RA-MDS, we extend a VAEs-based MDS framework by jointly considering news documents and reader comments. (3) Experimental results show that reader comments can improve the summarization performance, which also demonstrates the usefulness of the dataset.\nWe employed some experts to conduct the tasks of data collection, aspect annotation, and summary writing as well as scrutinizing.",

Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans.

        "answer": "Most DG methods assume p(y|x) remains constant and only p(x) changes, as this is the type of distribution shift encountered in popular DG benchmarks. However, it’s worth noting that our theoretical analysis applies to both situations: change in p(x) and change in p(y|x). We have added some discussion about this in the paper.",
        "evidence": "Machine learning systems have shown exceptional performance on numerous tasks in computer vision and beyond. However performance drops rapidly when the standard assumption of i.i.d. training and testing data is violated. This domain-shift phenomenon occurs widely in many applications of machine learning, and often leads to disappointing results in practical machine learning deployments, since data 'in the wild' is almost inevitably different from reference training sets.\nGiven the practical significance of this issue, a large number of methods have been proposed that aim to improve models' robustness to deployment under a different distribution than used for training, a problem setting known as domain generalisation (DG). These methods span diverse approaches such as specialised neural architectures, data augmentation strategies, and regularisers. Nevertheless, the DG problem setting is difficult to model formally for principled derivation and theoretical analysis of algorithms, the target domain of interest is unobservable during training, and cannot be directly approximated by the training domains due to unknown distribution shift. Therefore the majority of these existing approaches are based on poorly understood empirical heuristics.\nTo make matters worse, a recent study by assessed the state of DG research with a carefully conducted comparative evaluation of algorithms on a large benchmark suite under a common platform. They found that published methods were not as effective as claimed, and in particular reported that 'no existing method reliably beats a well tuned empirical risk minimization (ERM) baseline'. We argue that this negative result highlights the need for better theory in this area in order to understand why existing algorithms have such erratic performance, and to guide the development of principled algorithms that are more effective and reliable.\nTo this end, our first contribution is to present an intuitive learning-theoretic bound for DG performance. Intuitively, while the held-out domain of interest is indeed unobservable during training, we can bound its performance using learning theoretic tools similar to the standard ones used to bound the performance on (unobserved) testing data given (observed) training data. In particular we show that the performance on a held out target domain is bounded by the performance on known source domains, plus two additional model complexity terms, that describe how much a model can possibly have overfitted to the training domains. This theoretical contribution leads to several insights. Firstly, our theory suggests that DG performance is governed by a trade-off between empirical risk and model complexity that is analogous to the corresponding and widely understood trade-off that explains generalisation in standard i.i.d. learning as an overfitting-underfitting trade-off. Based on this, we hypothesise that performance variability is determined by implicit or explicit regularisation. That is, the plethora of different strategies available from data-augmentation to specialised optimisers -actually affect DG performance by explicitly or implicitly choosing different fit-complexity trade-offs. We corroborate this hypothesis by evaluating a number of models in the DomainBed suite in terms of complexity, and showing that their apparently erratic performance in is actually consistent with an explanation in terms of implied complexity.\nPractically, our analysis suggests that the model selection strategy) is a factor in DG performance that is at least as important as the actual mechanism of model complexity control (i.e., Tuning of regularisation strength vs specific parametric design of regulariser). In particular, regularisation should be stronger when optimizing for future DG performance than when optimizing for performance on seen domains. Unfortunately, model complexity is hard to carefully control in deep learning due to the large number of relevant factors (architecture, regularisers, implicit regularisation from optimiser, etc). attempted to address this by hyper-parameter search in the DomainBed benchmark, but are hampered by the computational infeasibility of accurate hyper-parameter search. In this paper, we use linear models and off-the-shelf self-supervised features to demonstrate much more clearly how cross-domain performance depends on complexity. Specifically, our theoretical and empirical results show that, contrary to the conclusion of, simple domain-wise cross-validation is a better objective to drive DG model selection.\nIn summary, based on our new generalisation bound, and associated empirical analysis, our takehome messages are: (i) Model fit vs complexity trade-off is a key determinant of DG performance, that explains existing DG algorithm performance variability. (ii) The complexity control strategy used to determine bias-variance trade-off is crucial in practice, with peak DG performance achieved when optimizing model complexity based on domain-wise validation. (iii) Regularisation required for optimal DG is greater than for conventional optimization for within-domain performance.\nHowever performance drops rapidly when the standard assumption of i.i.d.training and testing data is violated. This domain-shift phenomenon occurs widely in many applications of machine learning (Csurka, 2017; Zhou et al., 2021; Koh et al., 2021), and often leads to disappointing results in practical machine learning deployments, since data ‘in the wild’ is almost inevitably different from reference training sets.",

The distribution of reports across different primary diagnoses and primary sites is reported in tab:report-distribution. The dataset was developed in three steps as follows.\nCollecting pathology reports: The total of 11,112 pathology reports were downloaded from NCI's Genomic Data Commons (GDC) dataset in PDF format BIBREF9 . Out of all PDF files, 1,949 reports were selected across multiple patients from four specific primary sites—thymus, testis, lung, and kidney. The selection was primarily made based on the quality of PDF files.\nCleaning reports: The next step was to extract the text content from these reports. Due to the significant time expense of manually re-typing all the pathology reports, we developed a new strategy to prepare our dataset.

However, neither where coffee was first cultivated nor direct evidence of its consumption prior to the 15th century have been found. Sufi monasteries in Yemen employed coffee as an aid to concentration during prayers. Coffee later spread to the Levant and Persia in the early 16th century; it caused some controversy on whether it was halal in Ottoman and Mamluk society. Coffee arrived in Italy the second half of the 16th century through commercial Mediterranean trade routes, while Central and Eastern Europeans learnt of coffee from the Ottomans. By the mid 17th century, it had reached India and the East Indies. Coffee houses would establish themselves in Western Europe by the late 17th century, especially in England and Germany. One of the earliest cultivations of coffee in the New World was when Gabriel de Clieu brought coffee seedlings to Martinique in 1720. These beans later sprouted 18,680 coffee trees which enabled its spread to other Caribbean islands like Saint-Domingue and also to Mexico. By 1788, Saint-Domingue supplied half the world's coffee. By 1852, globally, Brazil became the largest producer of coffee and has held that status ever since. The period since 1950 saw the widening of the playing field due to the emergence of several other major producers, notably Colombia, Ivory Coast, Ethiopia, and Vietnam; the latter overtook Colombia and became the second-largest producer in 1999.

        "answer": "The first thing you must do is preheat your oven up as high as it will go. It takes longer than you think to heat your oven up all the way! You want to give your oven at least 30 minutes to preheat. If you have a pizza stone, make sure it’s inside the preheating oven.\nFor highend ovens, this can be up to 550 degrees F. For regular ovens, they are not going above 475 F. Pizza is traditionally cooked in 900 or 1,000 degree ovens. We can’t get our ovens at home quite that hot, but we want to get as close as we can. Figure out what your oven can do and crank up the heat.\nStart out with about 12-16 ounces of dough. Any pizza dough, homemade or store bought, will work for this recipe.\nPlace your ball of dough in the center of your work surface and use your hands to press it down, starting from the center. Keep gently patting out the dough, moving the dough outward from the center. I like to leave a pretty healthy crust on the edges of my dough.\nContinue patting and stretching the dough gently with your hands until it is about 12 inches across. Of course you can use a rolling pin if you want! (Use your hands to lift up the edges of the pizza when you are done to get more a lip for the crust.)\nAt this point, transfer the dough to a square of parchment paper. I highly recommend using parchment paper because it’s SO much easier transferring your pizza into the oven.\nStretch and arrange the dough on the parchment paper. The dough shrinks a bit when you pick it up to transfer, just gently stretch it out again.\nDrizzle a bit of olive oil over the top of your dough. Use your hands or a pastry brush to rub the oil all over the top of the dough, especially the edges of the crust. This layer of oil helps the toppings stay separate from the dough, helping it cook more evenly. It also tastes delicious, especially on your crust. \nOnce the oven is up to temperature, we are going to do a 1 to 2 minute par bake.\nSome of my favorite pizza toppings:\nJust Cheese: Any will work: Mozzarella, Fontina, Parmesan, and Gorgonzola would be amazing.\nPepperoni\nMeat Lovers: Pepperoni, salami, Italian sausage, ham, bacon\nHawaiian: Canadian bacon, pineapple\nMargherita: fresh mozzarella, fresh basil, tomatoes\nBBQ: Use barbecue sauce instead of tomato sauce, then rotisserie chicken, red onions, bacon\nVeggie pizza: spinach, tomato, corn, peppers, red onion, mushrooms\nBuffalo: Use Frank’s sauce instead of tomato sauce, then add rotisserie chicken, garlic, blue cheese, red onions\nOnce your pizza is in the oven, you need to cook it for about 8-12 minutes. This is of course going to depend on how hot your oven is, and how thick your pizza is. The crust should be golden brown, and the cheese should be bubbly and also starting to brown. If you don’t have a pizza stone, use a spatula to lift the edge of your pizza to make sure that it is browning all across the center on bottom. If the bottom is still white, you are looking at a doughy pizza. Leave it in longer.",

        "evidence": "One interesting pattern is that the ethnicity/race of babies doesn't seem to be mentioned unless the baby is black or asian. In other words: white seems to be the default, and others seem to be marked. How can we tell whether or not the data is actually biased?\nWe don't know whether or not an entity belongs to a particular social class (in this case: ethnic group) until it is marked as such. But we can approximate the proportion by looking at all the images where the annotators have used a marker (in this case: adjectives like black, white, asian), and for those images count how many descriptions (out of five) contain a marker. This gives us an upper bound that tells us how often ethnicity is indicated by the annotators. Note that this upper bound lies somewhere between 20% (one description) and 100% (5 descriptions). Figure TABREF22 presents count data for the ethnic marking of babies. It includes two false positives (talking about a white baby stroller rather than a white baby). In the Asian group there is an additional complication: sometimes the mother gets marked rather than the baby. E.g. An Asian woman holds a baby girl. I have counted these occurrences as well.\nThe numbers in Table TABREF22 are striking: there seems to be a real, systematic difference in ethnicity marking between the groups. We can take one step further and look at all the 697 pictures with the word `baby' in it. If there turn out to be disproportionately many white babies, this strengthens the conclusion that the dataset is biased.\nI have manually categorized each of the baby images. There are 504 white, 66 asian, and 36 black babies. 73 images do not contain a baby, and 18 images do not fall into any of the other categories. While this does bring down the average number of times each category was marked, it also increases the contrast between white babies (who get marked in less than 1% of the images) and asian/black babies (who get marked much more often). A next step would be to see whether these observations also hold for other age groups, i.e. children and adults.

Because the number of received review may greatly influence the reliability of the review score. From Table TABREF8 we can see that many responses on Zhihu Live receive no review at all, which are useless for quality evaluation.\nOne of the most challenging problems is no unique standard to evaluate a Zhihu Live as a low-quality or high-quality one. A collection of people may highly praise a Zhihu Live while others may not. In order to remove the sample bias, we delete those records whose review count is less than Q1 (11). So we get 5477 records which belong to 18 different fields.\nThe statistics of review scores after deletion are shown in Table TABREF9 . The mean score of 5477 records is 4.51, and the variance is 0.16. It indicates that the majority of Zhihu Lives are of high quality, and the users' scores are relatively stable.\nBadge in Zhihu represents identity authentication of public figures and high-quality answerers. Only those who hold a Ph.D. degree or experts in a specific domain can be granted a badge. Hence, these speakers tend to host high-quality Zhihu Lives theoretically. Table TABREF10 shows that 3286 speakers hold no badge, 1475 speakers hold 1 badge, and 446 speakers hold 2 badges, respectively. The average score of Zhihu Lives given by two badges holders is slightly higher than others. We can conclude that whether the speaker holds badges does have slightly influence on the Zhihu Live quality ratings, which is consistent with our supposition.\nFurthermore, we calculate the average scores of different Zhihu Live types (See Table TABREF11 ).

Not all plants look green though, due to the ability to reflect other wavelengths of light. When plants lose chlorophyll they will tend to lose the green color.

After gestating for 12 months, a bull shark may give birth to 1 to 13 live young.\n\nThey are viviparous, born live and free-swimming. The young are about 70 cm (27.6 in) at birth. The bull shark does not rear its young; the young bull sharks are born into flat, protected areas. Coastal lagoons, river mouths, and other low-salinity estuaries are common nursery habitats.\n\nThe male bull shark is able to begin reproducing around the age of 15 years while the female cannot begin reproducing until the age of 18 years. The size of a fully matured female bull shark to produce viable eggs for fertilization seems to be 175 cm to 235 cm. The courting routine between bull sharks has not been observed in detail as of yet. The male likely bites the female on the tail until she can turn upside down and the male can copulate at that point. Mature females commonly have scratches from the mating process.",

        "answer": "By representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors.",
        "evidence": "Low dimensional word representations (embeddings) have become a key component in modern NLP systems for language modeling, parsing, sentiment classification, and many others. These embeddings are usually derived by employing the distributional hypothesis: that similar words appear in similar contexts BIBREF0 .\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix BIBREF1 . The most well-known predictive model, which has become eponymous with word embedding, is word2vec BIBREF2 . Popular counting models include PPMI-SVD BIBREF3 , GloVe BIBREF4 , and LexVec BIBREF5 .\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.\nfastText BIBREF6 addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors. This addresses both issues above as learned information is shared through the n-gram vectors and from these OOV word representations can be constructed.\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , but the method proposed here should transfer to GloVe unchanged.\nThe LexVec objective is modified such that a word's vector is the sum of all its subword vectors.\nWe compare 1) the use of n-gram subwords, like fastText, and 2) unsupervised morphemes identified using Morfessor BIBREF11 to learn whether more linguistically motivated subwords offer any advantage over simple n-grams.\nTo evaluate the impact subword information has on in-vocabulary (IV) word representations, we run intrinsic evaluations consisting of word similarity and word analogy tasks. The incorporation of subword information results in similar gains (and losses) to that of fastText over Skip-gram. Whereas incorporating n-gram subwords tends to capture more syntactic information, unsupervised morphemes better preserve semantics while also improving syntactic results. Given that intrinsic performance can correlate poorly with performance on downstream tasks BIBREF12 , we also conduct evaluation using the VecEval suite of tasks BIBREF13 , in which\nall subword models, including fastText, show no significant improvement over word-level models.\nWe verify the model's ability to represent OOV words by quantitatively evaluating nearest-neighbors. Results show that, like fastText, both LexVec n-gram and (to a lesser degree) unsupervised morpheme models give coherent answers.\nThis paper discusses related word ( $§$ \"Related Work\" ), introduces the subword LexVec model ( $§$ \"Subword LexVec\" ), describes experiments ( $§$ \"Materials\" ), analyzes results ( $§$ \"Results\" ), and concludes with ideas for future works ( $§$ \"Conclusion and Future Work\" ).\nfastText (Bojanowski et al., 2017) addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors.",

Gabon enjoys a per capita income four times that of most nations of sub-Saharan Africa, its reliance on resource extraction industry releasing much of the population from extreme poverty.\n\nThe country is rich in natural resources such as timber, manganese and oil. The country is the fifth largest oil producing nation in Africa, which has helped drive its strong growth in the later 20th century.\n\nThe oil sector now accounts for 50% of GDP and 80% of exports. Although there have been recent offshore finds, oil production is now declining from its peak of 370,000 barrels per day (59,000 m3/d) in 1997, and periods of low oil prices have had a negative impact on government revenues and the economy. In 2012 there were six active oil rigs in Gabon.\n\nThe government has plans to diversify its economy away from its dwindling oil reserves. The government announced in 2012 that it would reassess exactly how much iron ore the Belinga site contains before awarding the concession to a mining company, most likely to be China's CMEC, which temporarily secured the rights to the ore in 2007.\n\nAround 80% of Gabonese live in cities.

The town was originally a remote settlement area for tin miners. However, due to its close proximity to the border of Malaysia-Thailand, Sintok was exposed to threats from the banned communist group.

        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\n1. We present a new method DOLORES of learning deep contextualized knowledge graph embeddings using a deep neural sequential model. 2. These embeddings are functions of hidden states of the deep neural model and can capture both context-independent and contextdependent cues. 3.

        "evidence": "Petrified wood, also known as petrified tree (from Ancient Greek πέτρα meaning 'rock' or 'stone'; literally 'wood turned into stone'), is the name given to a special type of fossilized wood, the fossilized remains of terrestrial vegetation. Petrifaction is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement. The organic materials making up cell walls have been replicated with minerals (mostly silica in the form of opal, chalcedony, or quartz). In some instances, the original structure of the stem tissue may be partially retained. Unlike other plant fossils, which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material.\n\nThe petrifaction process occurs underground, when wood becomes buried in water or volcanic ash. The presence of water reduces the availability of oxygen which inhibits aerobic decomposition by bacteria and fungi. Mineral-laden water flowing through the sediments may lead to permineralization, which occurs when minerals precipitate out of solution filling the interiors of cells and other empty spaces. During replacement, the plant's cell walls act as a template for mineralization. There needs to be a balance between the decay of cellulose and lignin and mineral templating for cellular detail to be preserved with fidelity. Most of the organic matter often decomposes, however some of the lignin may remain. Silica in the form of opal-A, can encrust and permeate wood relatively quickly in hot spring environments. However, petrified wood is most commonly associated with trees that were buried in fine grained sediments of deltas and floodplains or volcanic lahars and ash beds. A forest where such material has petrified becomes known as a petrified forest.",

        "evidence": "Multi-way Classification: The first section of table 3 shows macro average F1-scores and accuracies of previous works. The second section of table 3 shows the multi-class classification results of our implemented baseline systems. Consistent with results of previous works, neural tensors, when applied to Bi-LSTMs, improved implicit discourse relation prediction performance. However, the performance on the three small classes (Comp, Cont and Temp) remains low.\nThe third section of table 3 shows the multi-class classification results of our proposed paragraph-level neural network models that capture inter-dependencies among discourse units. The first row shows the performance of a variant of our basic model, where we only identify implicit relations and ignore identifying explicit relations by setting the $\\alpha $ in equation (5) to be 0. Compared with the baseline Bi-LSTM model, the only difference is that this model considers paragraph-wide contexts and model inter-dependencies among discourse units when building representation for individual DU. We can see that this model has greatly improved implicit relation classification performance across all the four relations and improved the macro-average F1-score by over 7 percents. In addition, compared with the baseline Bi-LSTM model with tensor, this model improved implicit relation classification performance across the three small classes, with clear performance gains of around 2 and 8 percents on contingency and temporal relations respectively, and overall improved the macro-average F1-score by 2.2 percents.\nThe second row shows the performance of our basic paragraph-level model which predicts both implicit and explicit discourse relations in a paragraph. Compared to the variant system (the first row), the basic model further improved the classification performance on the first three implicit relations. Especially on the contingency relation, the classification performance was improved by another 1.42 percents. Moreover, the basic model yields good performance for recognizing explicit discourse relations as well, which is comparable with previous best result (92.05% macro F1-score and 93.09% accuracy as reported in BIBREF11 ).\nAfter untying parameters in the softmax prediction layer, implicit discourse relation classification performance was improved across all four relations, meanwhile, the explicit discourse relation classification performance was also improved. The CRF layer further improved implicit discourse relation recognition performance on the three small classes. In summary, our full paragraph-level neural network model achieves the best macro-average F1-score of 48.82% in predicting implicit discourse relations, which outperforms previous neural tensor network models (e.g., BIBREF18 ) by more than 2 percents and outperforms the best previous system BIBREF19 by 1 percent.\nBinary Classification: From table 4 , we can see that compared against the best previous systems, our paragraph-level model with untied parameters in the prediction layer achieves F1-score improvements of 6 points on Comparison and 7 points on Temporal, which demonstrates that paragraph-wide contexts are important in detecting minority discourse relations. Note that the CRF layer of the model is not suitable for binary classification.\nIn summary, our full paragraph-level neural network model achieves the best macro-average F1-score of 48.82% in predicting implicit discourse relations, which outperforms previous neural tensor network models (e.g., (Lei et al., 2017)) by more than 2 percents and outperforms the best previous system (Lan et al., 2017) by 1 percent.",

While bonobos are now recognized as a distinct species in their own right, they were initially thought to be a subspecies of chimpanzee (Pan troglodytes) due to the physical similarities between the two species. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina (composed entirely by the genus Pan) are collectively termed panins.\n\nThe bonobo is distinguished by relatively long legs, pink lips, dark face, tail-tuft through adulthood, and parted long hair on its head. It is found in a 500,000 km2 (190,000 sq mi) area of the Congo Basin in the Democratic Republic of the Congo, Central Africa. The species is frugivorous and inhabits primary and secondary forests, including seasonally inundated swamp forests. Because of political instability in the region and the timidity of bonobos, there has been relatively little field work done observing the species in its natural habitat.\n\nAlong with the common chimpanzee, the bonobo is the closest extant relative to humans. As the two species are not proficient swimmers, the formation of the Congo River 1.5–2 million years ago possibly led to the speciation of the bonobo. Bonobos live south of the river, and thereby were separated from the ancestors of the common chimpanzee, which live north of the river. There are no concrete data on population numbers, but the estimate is between 29,500 and 50,000 individuals. The species is listed as Endangered on the IUCN Red List and is threatened by habitat destruction and human population growth and movement, though commercial poaching is the most prominent threat. Bonobos typically live 40 years in captivity; their lifespan in the wild is unknown, but it is almost certainly much shorter.",

        "evidence": "Language modeling is a probabilistic description of language phenomenon. It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nIt is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.

A versatile and well-rounded attacker, from a tactical standpoint, Ibrahimović is capable of playing anywhere along the front line, due to his ability to both create and score goals for his team, although he is most often deployed as a striker, due to his composure and eye for goal. He has also functioned in a more creative playmaking role at times, as a supporting forward or even as a number 10, in particular in his later career, after losing some of his pace and stamina with age; this deeper position allows him to drop into midfield to pick up the ball, where he can utilize his technical ability, vision, passing, and movement to create space and provide assists for teammates. While naturally right-footed, Ibrahimović is a powerful and accurate striker of the ball from both inside or outside the penalty area with either foot, and is also known for his accuracy from penalties and dead ball situations. An accurate finisher with his head as well as with his feet, his height, elevation, and strength often give him an advantage at winning aerial challenges, and also allow him to function as a \"target man\"; despite his large stature, Ibrahimović is uncommonly agile for a player of his size, and his athleticism and ability in the air have seen him score several goals from acrobatic strikes and volleys throughout his career, which earned him the moniker Ibracadabra in the Italian media.

In the revised draft, we have corrected all relevant statements.

Spatiotemporal modes are considered to have the following properties:\n- A spatiotemporal mode refers to a representation subspace that corresponds to a family of similar, but not predefined, visual dynamics.- Multiple spatiotemporal modes naturally exist in real-world data, even in a single frame.- We assume the i.i.d. setup to allow all videos to share the same set of spatiotemporal modes in a dataset. Different data may have different compositional structures over the modes.Through the new statements, one would **NOT** expect each sequence to correspond to a single spatiotemporal mode. More precisely, each sequence may be mixed up by a sequence-independent weighted combination from a set of spatiotemporal modes, and each mode may correspond to a compact dynamical component (modeled by the *mode slot*) underlying many sequences.

A spatiotemporal mode refers to a representation subspace that corresponds to a family of similar, but not predefined, visual dynamics.\n2. Multiple spatiotemporal modes naturally exist in real-world data, even in a single frame.\n3. We assume the i.i.d. setup to allow all videos to share the same set of spatiotemporal modes in a dataset. Different data may have different compositional structures over the modes.\nUnder these assumptions, video prediction models are required to (i) decouple the potentially mixed spatiotemporal modes from raw video frames, (ii) understand the compositional structures on top of the learned modes, and (iii) learn the state transitions based on the compositional structures.\nOtherwise, since the learned dynamics with respect to different modes may interfere and compete during training, it remains challenging for the prior art in video prediction to generate less blurry future frames based on an ambiguous understanding of mixed physical processes. We refer to this empirical phenomenon as spatiotemporal mode collapse (STMC), which is mainly caused by the collapse of learned representations into invalid subspaces when compromising to multiple spatiotemporal modes in the training set. Unlike the widely concerned mode collapse problem in generative adversarial networks, STMC has not drawn much attention because predictive learning is supposed to be well constrained by the image reconstruction loss. However, due to the limitation of model size, STMC occurs when the model cannot effectively decouple mixed spatiotemporal modes and infer their\nPredictive models collapse to blurry motion in the presence of complex dynamics modes underlying structures. As a result, its responses to different modes tend to lose diversity and may collapse to a meaningless average of multiple representation subspaces of valid modes.\nIn Figure (left), we can observe the existence of STMC on a large-scale video dataset named RoboNet, in which potential spatiotemporal modes may come from seven different robot platforms (e.g., Baxter and WidowX), four data collection environments (e.g., Berkeley and Stanford), and a variety of unlabeled robot control tasks (e.g., pushing and grasping). An additional outcome of STMC is that we can achieve a performance gain when training individual models in separate subsets with remarkably different visual dynamics, as shown in Figure (right). However, such a dilemma prevents the model from growing into big ones that allow scalable training on large-scale, natively multimodal spatiotemporal sequences.\nWe explore STMC for the first time in unsupervised predictive learning. The core idea is to provide a strong inductive bias for the predictive model to discover the compositional structures of latent modes. To this end, we propose ModeRNN, a new modular recurrent architecture that learns structured hidden representations through a set of mode slots 1 , where each of them responds to the representation subspace of a single spatiotemporal mode. ModeRNN also introduces a decoupling-aggregation framework to process the slot features in three stages, which is completely different from existing predictive models with modular architectures.\nThe first stage is recurrent state interaction and slot binding, in which we use the multi-head attention mechanism to enable the memory state to interact with the input state and previous hidden state of RNNs. We name the memory state \"slot bus\", because for each sequence, it is initialized from a multi-variate Gaussian distribution with learnable parameters, and thereafter refined using the slot features at each time step. By using the slot bus as the queries, multi-head attention can naturally decouple modular components from hidden representations and bind them to particular mode slots. Features in each slot are then independently modeled using per-slot convolutional parameters. The second stage in each ModeRNN unit is slot fusion, motivated by the assumption that, there can be multiple spatiotemporal modes in a single video and similar videos can be represented by similar compositional structures over the mode slots. Therefore, we assign slot features with learnable importance weights and aggregate them into a unified hidden representation, which is then used in the third stage to update the slot bus and generate the output state of the ModeRNN unit.\nWe empirically show the existence of STMC on five datasets, and include the results on three realworld datasets in the manuscript, including the large-scale RoboNet dataset that has various data collection environments and multiple robot control tasks, the KTH dataset with six types of human actions that has been widely used by previous literature, and the radar echo dataset for precipitation forecasting that contains time-varying modes of seasonal climates. In addition, we include results on a Mixed Moving MNIST dataset and the Human3.6M dataset in the appendix. In a series of quantitative and visualization results, we demonstrate the effectiveness of ModeRNN in mitigating STMC and learning from highly entangled visual dynamics.\nFor clarity, in the following discussion, spatiotemporal modes are considered to have the following properties: 1. A spatiotemporal mode refers to a representation subspace that corresponds to a family of similar, but not predefined, visual dynamics. 2. Multiple spatiotemporal modes naturally exist in real-world data, even in a single frame. 3. We assume the i.i.d. setup to allow all videos to share the same set of spatiotemporal modes in a dataset.

The two models are trained with three mentioned datasets, which are English-sportball, GT-sportball, UIT-ViIC. After training, 924 images from validation subset for each dataset are used to validate the our models.\nAs can be seen in Table TABREF36, with model from Pytorch tutorial, MS-COCO English captions categorized with sportball yields better results than the two Vietnamese datasets. However, as number of consecutive words considered (BLEU gram) increase, UIT-ViIC’s BLEU scores start to pass that of English sportball and their gaps keep growing. The ROUGE-L and CIDEr-D scores for UIT-ViIC model prove the same thing, and interestingly, we can observe that the CIDEr-D score for the UIT-ViIC model surpasses English-sportball counterpart.\nThe same conclusion can be said from Table TABREF36. Show and Tell model’s results show that MS-COCO sportball English captions only gives better result at BLEU-1. From BLEU-3 to BLEU-4, both GT-sportball and UIT-ViIC yield superior scores to English-sportball. Besides, when limiting MS-COCO English dataset to sportball category only, the results are higher (0.689, 0.501, 0.355, 0.252) than when the model is trained on MS-COCO with all images, which scored only 0.629, 0.436, 0.290, 0.193 (results without tuning in 2018) from BLEU-1 to BLEU-4 respectively.\nWhen we compare between two Vietnamese datasets, UIT-ViIC models perform better than sportball dataset translated automatically, GT-sportball. The gaps between the two results sets are more trivial in NIC model, and the numbers get smaller as the BLEU’s n-gram increase.\nIn Fig. FIGREF37, two images inputted into the models generate two Vietnamese captions that are able to describe accurately the sport game, which is soccer. The two models can also differentiate if there is more than one person in the images. However, when comparing GT-sportball outputs with UIT-ViIC ones in both images, UIT-ViIC yield captions that sound more naturally, considering Vietnamese language. Furthermore, UIT-ViIC demonstrates the specific action of the sport more accurately than GT-sportball. For example, in the below image of Fig. FIGREF37, UIT-ViIC tells the exact action (the man is preparing to throw the ball), whereas GT-sportball is mistaken (the man swing the bat). The confusion of GT-sportball happens due to GT-sportball train set is translated from original MS-COCO dataset, which is annotated in more various perspective and wider vocabulary range with the dataset size is not big enough.\nThere are cases when the main objects are too small, both English and GT - sportball captions tell the unexpected sport, which is tennis instead of baseball, for instance. Nevertheless, the majority of UIT-ViIC captions can tell the correct type of sport and action, even though the gender and age identifications still need to be improved.\nNevertheless, the majority of UIT-ViIC captions can tell the correct type of sport and action, even though the gender and age identifications still need to be improved.",

Later on, and in a decisive fashion, Darío was influenced by the parnassians: Théophile Gautier, Catulle Mendès, and José María de Heredia. Another decisive influence was the writer of prose and poetry and national hero of Cuba, Jose Martí. The final defining element of Darianian aesthetic is his admiration towards the symbolists, especially Paul Verlaine. Recapitulating his own poetic trajectory in the initial poem of Cantos de vida y esperanza (1905) Darío himself synthesized his main influences when he affirms that he was \"strong with Hugo and ambiguous with Verlaine\" (\"con Hugo fuerte y con Verlaine ambiguo\".)\n\nIn the section \"Palabras Liminares\" of Prosas Profanas (1896) he had already written a paragraph that reveals the importance of French culture in the development of his literary work:\n\nThe old Spaniard with a white beard points towards a series of illustrious portraits: \"This one—he says—is the great Miguel de Cervantes Saavedra, one-handed genius; this one is Lope de Vega, this one is Garcilaso, this one Quintana.\" I ask him for the noble man Gracián, for Teresa of Ávila, for the brave Góngora and the strongest of all, Francisco de Quevedo y Villegas. Then I say: \"Shakespeare! Dante! Hugo...! (and in my head: Verlaine...!)\"\nThen, when saying goodbye: \"-Old man, it is important to say: my wife is from my land; my mistress is from Paris.\"\n\nLos raros is an illustrative volume regarding literary tastes, which he published on the same year as Prosas profanas, and dedicated to briefly glossing some of the writers and intellectuals towards whom he felt profound admiration. Amongst those in the book we find Edgar Allan Poe, Villiers de l'Isle Adam, Léon Bloy, Paul Verlaine, Lautréamont, Eugénio de Castro and José Martí (the latter being the only one mentioned who wrote their literary work in Spanish.) The predominance of French culture is more than evident. Darío wrote: \"Modernism is nothing more than Spanish verse and prose passed through the fine sieve of the good French verse and the good French prose.\" Setting aside his initial stage, before Azul..., in which his poetry owes a great deal to the great names of 19th-century Spanish poetry, such as Núñez de Arce and Campoamor, Darío was a great admirer of Bécquer. Spanish themes are well represented in his work, already in Prosas profanas and, specially, after his second trip to Spain, in 1899. Conscious of contemporaneous Spanish decadence in politics and the arts (a preoccupation he shared with the so-called Generation of '98), he frequently was inspired by characters and elements of the past. Regarding authors in other languages, it is worth mentioning that he felt a profound admiration towards three writers from the United States: Ralph Waldo Emerson, Edgar Allan Poe and Walt Whitman.[citation needed]",

        "answer": "The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. Although the macrostructure of the two hemispheres appears to be almost identical, different composition of neuronal networks allows for specialized function that is different in each hemisphere.\n\nLateralization of brain structures is based on general trends expressed in healthy patients; however, there are numerous counterexamples to each generalization. Each human's brain develops differently, leading to unique lateralization in individuals. This is different from specialization, as lateralization refers only to the function of one structure divided between two hemispheres. Specialization is much easier to observe as a trend, since it has a stronger anthropological history.\n\nThe best example of an established lateralization is that of Broca's and Wernicke's areas, where both are often found exclusively on the left hemisphere. Function lateralization, such as semantics, intonation, accentuation, and prosody, has since been called into question and largely been found to have a neuronal basis in both hemispheres. Another example is that each hemisphere in the brain tends to represent one side of the body. In the cerebellum, this is the same body side, but in the forebrain this is predominantly the contralateral side.\n\nLanguage functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right-handed individuals. While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers.\n\nBroca's area and Wernicke's area, associated with the production of speech and comprehension of speech, respectively, are located in the left cerebral hemisphere for about 95% of right-handers but about 70% of left-handers. 69  Individuals who speak multiple languages demonstrate separate speech areas for each language.\n\nThe processing of basic sensory information is lateralized by being divided into left and right sides of the body or the space around the body.\n\nIn vision, about half the neurons of the optic nerve from each eye cross to project to the opposite hemisphere, and about half do not cross to project to the hemisphere on the same side. This means that the left side of the visual field is processed largely by the visual cortex of the right hemisphere and vice versa for the right side of the visual field.\n\nIn hearing, about 90% of the neurons of the auditory nerve from one ear cross to project to the auditory cortex of the opposite hemisphere.\n\nIn the sense of touch, most of the neurons from the skin cross to project to the somatosensory cortex of the opposite hemisphere.\n\nBecause of this functional division of the left and right sides of the body and of the space that surrounds it, the processing of information in the sensory cortices is essentially identical. That is, the processing of visual and auditory stimuli, spatial manipulation, facial perception, and artistic ability are represented bilaterally. Numerical estimation, comparison and online calculation depend on bilateral parietal regions while exact calculation and fact retrieval are associated with left parietal regions, perhaps due to their ties to linguistic processing.\n\nRather than just being a series of places where different brain modules occur, there are running similarities in the kind of function seen in each side, for instance how right-side impairment of drawing ability making patients draw the parts of the subject matter with wholly incoherent relationships, or where the kind of left-side damage seen in language impairment not damaging the patient's ability to catch the significance of intonation in speech. This has led British psychiatrist Iain McGilchrist to view the two hemispheres as having different value systems, where the left hemisphere tends to reduce complex matters such as ethics to rules and measures, and the right hemisphere is disposed to the holistic and metaphorical.\n\nDepression is linked with a hyperactive right hemisphere. The delusional misidentification syndromes, reduplicative paramnesia and Capgras delusion are also often the result of right hemisphere lesions.\n\nDamage to either the right or left hemisphere, and its resulting deficits provide insight into the function of the damaged area. Left hemisphere damage has many effects on language production and perception. Damage or lesions to the right hemisphere can result in a lack of emotional prosody or intonation when speaking. Right hemisphere damage also has grave effects on understanding discourse. People with damage to the right hemisphere have a reduced ability to generate inferences, comprehend and produce main concepts, and a reduced ability to manage alternative meanings. Furthermore, people with right hemisphere damage often exhibit discourse that is abrupt and perfunctory or verbose and excessive. They can also have pragmatic deficits in situations of turn taking, topic maintenance and shared knowledge.\n\nLateral brain damage can also affect visual perceptual spatial resolution. People with left hemisphere damage may have impaired perception of high resolution, or detailed, aspects of an image. People with right hemisphere damage may have impaired perception of low resolution, or big picture, aspects of an image.\n\nIf a specific region of the brain, or even an entire hemisphere, is injured or destroyed, its functions can sometimes be assumed by a neighboring region in the same hemisphere or the corresponding region in the other hemisphere, depending upon the area damaged and the patient's age. When injury interferes with pathways from one area to another, alternative (indirect) connections may develop to communicate information with detached areas, despite the inefficiencies.\n\nBroca's aphasia is a specific type of expressive aphasia and is so named due to the aphasia that results from damage or lesions to the Broca's area of the brain, that exists most commonly in the left inferior frontal hemisphere. Thus, the aphasia that develops from the lack of functioning of the Broca's area is an expressive and non-fluent aphasia. It is called 'non-fluent' due to the issues that arise because Broca's area is critical for language pronunciation and production. The area controls some motor aspects of speech production and articulation of thoughts to words and as such lesions to the area result in specific non-fluent aphasia.\n\nWernicke's aphasia is the result of damage to the area of the brain that is commonly in the left hemisphere above the Sylvian fissure. Damage to this area causes primarily a deficit in language comprehension. While the ability to speak fluently with normal melodic intonation is spared, the language produced by a person with Wernicke's aphasia is riddled with semantic errors and may sound nonsensical to the listener. Wernicke's aphasia is characterized by phonemic paraphasias, neologism or jargon. Another characteristic of a person with Wernicke's aphasia is that they are unconcerned by the mistakes that they are making.\n\nTerence Hines states that the research on brain lateralization is valid as a research program, though commercial promoters have applied it to promote subjects and products far outside the implications of the research. For example, the implications of the research have no bearing on psychological interventions such as eye movement desensitization and reprocessing (EMDR) and neurolinguistic programming, brain-training equipment, or management training.\n\nSome popularizations oversimplify the science about lateralization, by presenting the functional differences between hemispheres as being more absolute than is actually the case. Interestingly, research has shown quite opposite function of brain lateralisation, i.e. left hemisphere creatively and chaotically links between concepts and right hemisphere tends to adhere to specific date and time, although generally adhering to the pattern of left-brain as linguistic interpretation and right brain as spatio-temporal.\n\nIn the 19th century and to a lesser extent the 20th, it was thought that each side of the brain was associated with a specific gender: the left corresponding with masculinity and the right with femininity and each half could function independently. The right side of the brain was seen as the inferior and thought to be prominent in women, savages, children, criminals, and the insane. A prime example of this in fictional literature can be seen in Robert Louis Stevenson's Strange Case of Dr. Jekyll and Mr. Hyde.",

It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977. The company's second computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user interfaces, including the 1984 original Macintosh, announced that year in a critically acclaimed advertisement. By 1985, the high cost of its products, and power struggles between executives, caused problems. Wozniak stepped back from Apple amicably and pursued other ventures, while Jobs resigned bitterly and founded NeXT, taking some Apple employees with him.\n\nAs the market for personal computers expanded and evolved throughout the 1990s, Apple lost considerable market share to the lower-priced duopoly of the Microsoft Windows operating system on Intel-powered PC clones (also known as \"Wintel\"). In 1997, weeks away from bankruptcy, the company bought NeXT to resolve Apple's unsuccessful operating system strategy and entice Jobs back to the company. Over the next decade, Jobs guided Apple back to profitability through a number of tactics including introducing the iMac, iPod, iPhone and iPad to critical acclaim, launching the \"Think different\" campaign and other memorable advertising campaigns, opening the Apple Store retail chain, and acquiring numerous companies to broaden the company's product portfolio.

We have also added more details to the corresponding part for further clarification in Section 4.1.",
        "evidence": "Following the scaling approach described in Section 3.3, we set 2× FLOPs of the initial or selected model from the previous step as the target hardware-cost in each step when individually scaling each factor, as summarized in Figure. All networks are trained for 300 epochs on ImageNet using the same training recipe with the one in DeiT, more details are included in Appendix E. We summarize our observations as follow: Scaled ViT models outperform SOTA DeiT models. As shown in Table, our scaled ViT models (e.g., DeiT-Scaled-Tiny/Small/Base) achieve a ↑0.4% ∼ ↑1.9% higher top-1 accuracy on ImageNet under the same FLOPs constraints. Specifically, our DeiT-Scaled-Tiny model chooses to use a smaller image resolution (i.e., 160×160 vs. 224×224) and more layers and a higher number of heads as compared to the SOTA DeiT-Tiny model, and thus achieves a ↑1.9% higher accuracy at the same cost in terms of FLOPs, while our DeiT-Scaled-Small/Base models choose to use a larger image resolution (i.e., 320/256×320/256 vs. 224×224) and more layers, together with a lower number of heads as compared to the SOTA DeiT-Small/Base model, helping them to achieve a ↑0.4% higher accuracy under similar FLOPs. This set of experiments shows that our simple search method can (1) effectively locate ViT models with better accuracy-FLOPs trade-offs and (2) automatically adapt different scaling factors towards the optimal accuracy-FLOPs trade-offs, e.g., different model shapes and structures at different scales of FLOPs.\nRandom permutation further boosts the performance. Inspired by the coarse-to-fine architecture selection scheme adopted in , we further randomly permute the scaling factors (i.e., d, h, e, r, I, and p) of each scaled model in Table. After the permutation, we select 24 architectures under the same target hardware-cost with the scaled model by iterative greedy search for each scaled model. Figure demonstrates that () such a random permutation can slightly push forward the frontier of accuracy-FLOPs trade-off (e.g., a ↑0.4% higher accuracy under similar FLOPs on top of the scaled models resulting from the adopted simple scaling method); and (2) our adopted iterative greedy search alone is sufficiently effective while requiring a lower exploration cost (e.g., 6 vs. 30 (6+24) models to be trained for each step as compared to such a search method together with the aforementioned permutation).  Scaled ViT also benefits from a longer training time. As pointed out by, training ViT models for more epochs (e.g., 1000 epochs) can further improve the achieved accuracy.\nDeiT\nTo verify whether the scaled ViT models can benefit from more training epochs, we train the models in Table for 1000 epochs following the training recipe in. As shown in Table, longer training epochs also help our scaled models (e.g., DeiT-Scaled-Tiny/Small) to achieve a higher accuracy, and thus, the advantage of our scaled models over DeiT is consistent under both the 300-epochs training recipe and 1000-epochs training recipe, e.g., a ↑1.9% higher accuracy over DeiT-Tiny with 300 epochs vs. a ↑1.7% higher accuracy over DeiT-Tiny with 1000 epochs.\nDrawn insights from scaling ViT. Based on the observations from the above experiments, especially the scaling strategies illustrated in Figure, we draw the following scaling insights dedicated to ViT:\n(1) When targeting relatively small models (i.e., with smaller FLOPs than DeiT-Scaled-Small), the optimal models tend to select \"scaling h (i.e., the number of heads)\" or \"scaling d (i.e., the number of layers)\" and a \"smaller I (i.e., the input image resolution)\" (e.g., 160 × 160 instead of the commonly used 224 × 224).\nFLOPs (G) ImageNet top-1 accuracy (%)\nFigure: Resulting models from our iterative greedy search, where models achieving the best accuracy-FLOPs trade-offs are marked as DeiT-Scaled-Tiny/Small/Base. The architecture configurations (i.e., sets of d, h, e, r, I, and p) leading to these best models are extracted as our scaling strategies dedicated to ViT.\n(2) When targeting relatively large models (i.e., with larger FLOPs than DeiT-Scaled-Small), the optimal models mainly select to \"scaling I (i.e., the input image resolution)\", while \"slowing down scaling h (i.e., number of heads)\" as compared to the case when targeting relatively small models.\nAfter the permutation, we select 24 architectures under the same target hardware-cost with the scaled model by iterative greedy search for each scaled model.",

A series of competitions has been devoted to grammatical error correction (GEC): the CoNLL-2013 shared task BIBREF0 , the CoNLL-2014 shared task BIBREF1 , and finally the BEA 2019 shared task BIBREF2 . This paper presents the contributions from the Cambridge University Engineering Department to the latest GEC competition at the BEA 2019 workshop.\nWe submitted systems to two different tracks. The low-resource track did not permit the use of parallel training data except a small development set with around 4K sentence pairs. For our low-resource system we extended our prior work on finite state transducer based GEC BIBREF3 to handle new error types such as punctuation errors as well as insertions and deletions of a small number of frequent words. For the restricted track, the organizers provided 1.2M pairs (560K without identity mappings) of corrected and uncorrected sentences. Our goal on the restricted track was to explore the potential of purely neural models for grammatical error correction. We confirm the results of BIBREF4 and report substantial gains by applying back-translation BIBREF5 to GEC – a data augmentation technique common in machine translation. Furthermore, we noticed that large parts of the training data do not match the target domain. We mitigated the domain gap by over-sampling the in-domain training corpus, and by fine-tuning through continued training. Our final model is an ensemble of four neural machine translation (NMT) models and two neural language models (LMs) with Transformer architecture BIBREF6 .

        "answer": "Gate mechanism and attention mechanism.",
        "evidence": "In recent years, the proliferation of fake news with various content, high-speed spreading, and extensive influence has become an increasingly alarming issue. A concrete instance was cited by Time Magazine in 2013 when a false announcement of Barack Obama's injury in a White House explosion “wiped off 130 Billion US Dollars in stock value in a matter of seconds\". Other examples, an analysis of the US Presidential Election in 2016 BIBREF0 revealed that fake news was widely shared during the three months prior to the election with 30 million total Facebook shares of 115 known pro-Trump fake stories and 7.6 million of 41 known pro-Clinton fake stories. Therefore, automatically detecting fake news has attracted significant research attention in both industries and academia.\nMost existing methods devise deep neural networks to capture credibility features for fake news detection. Some methods provide in-depth analysis of text features, e.g., linguistic BIBREF1, semantic BIBREF2, emotional BIBREF3, stylistic BIBREF4, etc. On this basis, some work additionally extracts social context features (a.k.a. meta-data features) as credibility features, including source-based BIBREF5, user-centered BIBREF6, post-based BIBREF7 and network-based BIBREF8, etc. These methods have attained a certain level of success. Additionally, recent researches BIBREF9, BIBREF10 find that doubtful and opposing voices against fake news are always triggered along with its propagation. Fake news tends to provoke controversies compared to real news BIBREF11, BIBREF12. Therefore, stance analysis of these controversies can serve as valuable credibility features for fake news detection.\nThere is an effective and novel way to improve the performance of fake news detection combined with stance analysis, which is to build multi-task learning models to jointly train both tasks BIBREF13, BIBREF14, BIBREF15. These approaches model information sharing and representation reinforcement between the two tasks, which expands valuable features for their respective tasks. However, prominent drawback to these methods and even typical multi-task learning methods, like the shared-private model, is that the shared features in the shared layer are equally sent to their respective tasks without filtering, which causes that some useless and even adverse features are mixed in different tasks, as shown in Figure FIGREF2(a). By that the network would be confused by these features, interfering effective sharing, and even mislead the predictions.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure FIGREF2(b)) to detect fake news by joining stance detection task. Specifically, we introduce a selected sharing layer into each task after the shared layer of the model for filtering shared features. The selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks. Besides, to better capture long-range dependencies and improve the parallelism of the model, we apply transformer encoder module BIBREF16 to our model for encoding input representations of both tasks. Experimental results reveal that the proposed model outperforms the compared methods and gains new benchmarks.\nIn summary, the contributions of this paper are as follows:\nWe explore a selected sharing layer relying on gate mechanism and attention mechanism, which can selectively capture valuable shared features between tasks of fake news detection and stance detection for respective tasks.\nThe transformer encoder is introduced into our model for encoding inputs of both tasks, which enhances the performance of our method by taking advantages of its long-range dependencies and parallelism.\nExperiments on two public, widely used fake news datasets demonstrate that our method significantly outperforms previous state-of-the-art methods.\nWe explore a selected sharing layer relying on gate mechanism and attention mechanism, which can selectively capture valuable shared features between tasks of fake news detection and stance detection for respective tasks.",

This theory originated with Czech philosopher Radovan Richta.\n\nMankind In Transition; A View of the Distant Past, the Present and the Far Future, Masefield Books, 1993. Technology (which Richta defines as \"a material entity created by the application of mental and physical effort to nature in order to achieve some value\") evolves in three stages: tools, machine, automation. This evolution, he says, follows two trends:\n\nThe pre-technological period, in which all other animal species remain today (aside from some avian and primate species) was a non-rational period of the early prehistoric man.\n\nThe emergence of technology, made possible by the development of the rational faculty, paved the way for the first stage: the tool. A tool provides a mechanical advantage in accomplishing a physical task, such as an arrow, plow, or hammer that augments physical labor to more efficiently achieve his objective. Later animal-powered tools such as the plow and the horse, increased the productivity of food production about tenfold over the technology of the hunter-gatherers. Tools allow one to do things impossible to accomplish with one's body alone, such as seeing minute visual detail with a microscope, manipulating heavy objects with a pulley and cart, or carrying volumes of water in a bucket.\n\nThe second technological stage was the creation of the machine. A machine (a powered machine to be more precise) is a tool that substitutes part of or all of the element of human physical effort, requiring only the control of its functions. Machines became widespread with the industrial revolution, though windmills, a type of machine, are much older.\n\nExamples of this include cars, trains, computers, and lights. Machines allow humans to tremendously exceed the limitations of their bodies. Putting a machine on the farm, a tractor, increased food productivity at least tenfold over the technology of the plow and the horse.\n\nThe third, and final stage of technological evolution is the automation. The automation is a machine that removes the element of human control with an automatic algorithm. Examples of machines that exhibit this characteristic are digital watches, automatic telephone switches, pacemakers, and computer programs.\n\nIt is crucial to understand that the three stages outline the introduction of the fundamental types of technology, and so all three continue to be widely used today. A spear, a plow, a pen, a knife, a glove, and an optical microscope are all examples of tools.",

        "question": "What does \"causes\" mean in Definition 25? I suppose this refers to actual causation, right?",
        "answer": "Yes. Again being sloppy, as Definition 19 does not use that term… I will simply write actual cause instead.",
        "evidence": "Actual Causes are those events which explain an output in the most general sense of explanation.\nThere is a lively literature on how to define actual causation using causal models, but for the reasons outlined above, this literature has yet to find its way into the XAI literature. I here aim to set this straight by explicitly connecting actual causation to the notions of explanation that we have come across. A concise counterfactual explanation is good when you can get it, but often you cannot get it, and thus we need a weaker notion of explanation that is more generally applicable. 7 (The causal counterpart of this message is what initiated the formal causation literature some fifty years ago.)\nIt is clear from the definitions that sufficient explanations are weaker than counterfactual explanations. But sufficient explanations ignore the counterfactual aspect entirely, which means they are of little value for action-guidance in the presence of an already existing observation. Therefore I define actual causes as parts of explanations that sit in between counterfactual and sufficient explanations: they are parts of good sufficient explanations such that there exist counterfactual values which would not have made the explanation better. This is weaker than demanding that the counterfactual values are part of a sufficient explanation of a different output, as we do for counterfactual explanations. Informally, X = x rather than X = x is an actual cause of Y = y if X = x is part of a good sufficient explanation for Y = y that could have not been made better by setting X to x .\nFirst I make precise how changing the values of some variables can turn a sufficient explanation into a better one.\nDefinition 18 If ((X = x, W = w), N ) is a sufficient explanation of Y = y, we say that X = x can replace X = x if there exists a dominating explanation that includes (X = x , W = w).\nThe following result ensures that the focus on W (instead of its subsets) in Definition 18 is without loss of generality.\nProposition 19 If ((X = x, W = w), N ) is a sufficient explanation of Y = y and there exists a dominating explanation ((X = x , A = a), B) for some values x and a ⊆ w, then X = x can replace X = x.\nDefinition 20 X = x rather than X = x is an actual cause of Y = y in (M, u) if it is part of a good sufficient explanation of Y = y in which X = x cannot be replaced by X = x .\nIf ((X = x, W = w), N ) is the relevant good explanation, we say that X = x rather than X = x is an actual cause of Y = y relative to (W = w, N ).\n6. Obviously this holds only if V \\ (X ∪ {Y }) consists of at least two elements. 7. Obviously you can always find some counterfactual explanation of an output, for changing all of the variables will always allow you to get a different output. But an explanation that involves too many variables is of little use.\nExcept for a minor technical difference regarding the implementation of minimality, Definition 20 is equivalent to the definition of causation I developed in previous work. Although I have here arrived at the same notion, I did so along a very different path, for in the previous work I did not draw any connection to explanations nor to action-guidance, but instead argued for the definition by contrasting it to other proposals for defining causation (including Definition 13).\nContrary to counterfactual explanations, actual causes do not guide you towards actions that, under the same conditions, would ensure the output to be different. But they do guide you towards actions that would not ensure the actual output under the same conditions as the actual action. For example, imagine a (very fortunate) applicant for whom X 1 = 250, 000, X 3 = 50, 000, and thus X 2 = 125, 000. Obviously their application is successful, and their income by itself offers a good explanation of this fact: X 1 = 250, 000 is a good direct sufficient explanation of Y = 1. Also, their income does not counterfactually explain the output, for the application would have been approved regardless of income. Yet we do have that X 1 = 250, 000 rather than X 1 = 200, 000 is an actual cause of the output, because we cannot replace X 1 = 250, 000 by X 1 = 200, 000 in our sufficient explanation (i.e., X 1 = 200, 000 is not a sufficient explanation of Y = 1). This is helpful for example if the applicant is considering changing jobs and would like to know whether they can use up their savings and still get their application approved.\nOne might wonder whether we need a separate definition of actual causation, as opposed to simply considering all parts of good sufficient explanations to be causes. The distinction between these two options lies in the existence of alternative actions that would make the actual explanation worse, and it are precisely those actions which make actual causes good guides towards action. Consider for example a situation in which a short-circuit starts a fire (F = 1) in an office building. The flames set off the sprinklers (S = 1), and those put out the flames, preventing the building from burning down (B = 0) -where all variables are binary. Matching equations for this story are: B = F ∧ ¬S, S = F . In this scenario, the fire offers a good sufficient explanation of the building not burning down relative to the sprinklers functioning as they should. But obviously it would be unwise to conclude from this that we should start fires in order to prevent buildings from burning down! This point can be brought out by noting that the fire is not an actual cause of the building not burning down, because there not being a fire would have offered a better sufficient explanation of this outcome, as it does not rely on the sprinklers functioning properly. (Concretely: F = 0 can replace F = 1 in the good sufficient explanation (F = 1, S) of B = 0.) Since sprinklers can malfunction, or can be made to malfunction by a malicious actor, the best action is to not set fires in a building, in accordance with actual causation.\nThe following result specifies the claim that actual causes sit in between counterfactual and sufficient explanations: counterfactual explanations always contain actual causes (and obviously not vice versa).\nTheorem 21 If X 1 = x 1 rather than X 1 = x 1 is a counterfactual explanation of Y = y in (M, u) (relative to some (W = w, N )) then for some X 2 ⊆ X 1 , X 2 = x 2 rather than X 2 = x 2 is an actual cause of Y = y in (M, u) (where x 2 and x 2 are the relevant restrictions to X 2 ).\nAn obvious strengthening of actual causation is to replace the existential quantifier over counterfactual values with a universal one, so that the actual values are the optimal values in terms of explanations.\nDefinition 22 X = x is an optimal cause of Y = y in (M, u) if X = x is part of a good sufficient explanation of Y = y in which X = x cannot be replaced. (I.e., there do not exist values x so that it could be replaced by those.)\nFinally, replacing strong sufficiency with direct sufficiency offers a notion of direct causation .\nWe can now present a final result regarding the limitation of Independence: the different notions of causation also reduce to each other.\nTheorem 25 If a causal model M satisfies Independence then the following statements are all equivalent:\n• there exist values x so that X = x rather than X = x is an actual cause of Y = y in (M, u).\n• X = x is part of a good sufficient explanation of Y = y in (M, u).\nTheorem 25 If a causal model M satisfies Independence then the following statements are all\nequivalent:\n• X = x is a direct cause of Y = y in (M,u).\n• there exist values x\n0\nso that X = x rather than X = x\n0\nis an actual cause of Y = y in\n(M,u).\n• X = x is part of a good sufficient explanation of Y = y in (M,u).",

        "evidence": "Franz Kafka (3 July 1883 – 3 June 1924) was a German-speaking Bohemian novelist and short-story writer based in Prague, who is widely regarded as one of the major figures of 20th-century literature. His work fuses elements of realism and the fantastic. It typically features isolated protagonists facing bizarre or surrealistic predicaments and incomprehensible socio-bureaucratic powers. It has been interpreted as exploring themes of alienation, existential anxiety, guilt, and absurdity. His best known works include the short story \"The Metamorphosis\" and novels The Trial and The Castle. The term Kafkaesque has entered English to describe absurd situations, like those depicted in his writing.\n\nKafka was born into a middle-class German-speaking Czech Jewish family in Prague, the capital of the Kingdom of Bohemia, then part of the Austro-Hungarian Empire (today the capital of the Czech Republic). He trained as a lawyer, and after completing his legal education was employed full-time by an insurance company, forcing him to relegate writing to his spare time. Over the course of his life, Kafka wrote hundreds of letters to family and close friends, including his father, with whom he had a strained and formal relationship. He became engaged to several women but never married. He died in obscurity in 1924 at the age of 40 from tuberculosis.\n\nKafka was a prolific writer, spending most of his free time writing, often late in the night. He burned an estimated 90 per cent of his total work due to his persistent struggles with self-doubt. Much of the remaining 10 per cent is lost or otherwise unpublished. Few of Kafka's works were published during his lifetime: the story collections Contemplation and A Country Doctor, and individual stories (such as \"The Metamorphosis\") were published in literary magazines but received little public attention.\n\nIn his will, Kafka instructed his close friend and literary executor Max Brod to destroy his unfinished works, including his novels The Trial, The Castle, and Amerika, but Brod ignored these instructions, and had much of his work published. Kafka's work became famous in German-speaking countries after World War II, influencing their literature, and it spread elsewhere in the world in the 1960s. It has since influenced a range of writers, critics, artists, and philosophers.",

        "answer": "Because predicting an explicit relation will help to reveal the pragmatic roles of its two DUs and reconstruct their representations, which will facilitate predicting neighboring implicit discourse relations that involve one of the DUs.",
        "evidence": "PDTB-style discourse relations, mostly defined between two adjacent text spans (i.e., discourse units, either clauses or sentences), specify how two discourse units are logically connected (e.g., causal, contrast). Recognizing discourse relations is one crucial step in discourse analysis and can be beneficial for many downstream NLP applications such as information extraction, machine translation and natural language generation.\nCommonly, explicit discourse relations were distinguished from implicit ones, depending on whether a discourse connective (e.g., “because” and “after”) appears between two discourse units BIBREF0 . While explicit discourse relation detection can be framed as a discourse connective disambiguation problem BIBREF1 , BIBREF2 and has achieved reasonable performance (F1 score $>$ 90%), implicit discourse relations have no discourse connective and are especially difficult to identify BIBREF3 , BIBREF2 , BIBREF4 . To fill the gap, implicit discourse relation prediction has drawn significant research interest recently and progress has been made BIBREF5 , BIBREF6 by modeling compositional meanings of two discourse units and exploiting word interactions between discourse units using neural tensor networks or attention mechanisms in neural nets. However, most of existing approaches ignore wider paragraph-level contexts beyond the two discourse units that are examined for predicting a discourse relation in between.\nTo further improve implicit discourse relation prediction, we aim to improve discourse unit representations by positioning a discourse unit (DU) in its wider context of a paragraph. The key observation is that semantic meaning of a DU can not be interpreted independently from the rest of the paragraph that contains it, or independently from the overall paragraph-level discourse structure that involve the DU. Considering the following paragraph with four discourse relations, one relation between each two adjacent DUs:\n(1): [The Butler, Wis., manufacturer went public at $15.75 a share in August 1987,] $_{DU1}$ and (Explicit-Expansion) [Mr. Sim's goal then was a $29 per-share price by 1992.] $_{DU2}$ (Implicit-Expansion) [Strong earnings growth helped achieve that price far ahead of schedule, in August 1988.] $_{DU3}$ (Implicit-Comparison) [The stock has since softened, trading around $25 a share last week and closing yesterday at $23 in national over-the-counter trading.] $_{DU4}$ But (Explicit-Comparison) [Mr. Sim has set a fresh target of $50 a share by the end of reaching that goal.] $_{DU5}$ \nClearly, each DU is an integral part of the paragraph and not independent from other units. First, predicting a discourse relation may require understanding wider paragraph-level contexts beyond two relevant DUs and the overall discourse structure of a paragraph. For example, the implicit “Comparison” discourse relation between DU3 and DU4 is difficult to identify without the background information (the history of per-share price) introduced in DU1 and DU2. Second, a DU may be involved in multiple discourse relations (e.g., DU4 is connected with both DU3 and DU5 with a “Comparison” relation), therefore the pragmatic meaning representation of a DU should reflect all the discourse relations the unit was involved in. Third, implicit discourse relation prediction should benefit from modeling discourse relation continuity and patterns in a paragraph that involve easy-to-identify explicit discourse relations (e.g., “Implicit-Comparison” relation is followed by “Explicit-Comparison” in the above example).\nFollowing these observations, we construct a neural net model to process a paragraph each time and jointly build meaning representations for all DUs in the paragraph. The learned DU representations are used to predict a sequence of discourse relations in the paragraph, including both implicit and explicit relations. Although explicit relations are not our focus, predicting an explicit relation will help to reveal the pragmatic roles of its two DUs and reconstruct their representations, which will facilitate predicting neighboring implicit discourse relations that involve one of the DUs.\nIn addition, we introduce two novel designs to further improve discourse relation classification performance of our paragraph-level neural net model. First, previous work has indicated that recognizing explicit and implicit discourse relations requires different strategies, we therefore untie parameters in the discourse relation prediction layer of the neural networks and train two separate classifiers for predicting explicit and implicit discourse relations respectively. This unique design has improved both implicit and explicit discourse relation identification performance. Second, we add a CRF layer on top of the discourse relation prediction layer to fine-tune a sequence of predicted discourse relations by modeling discourse relation continuity and patterns in a paragraph.\nExperimental results show that the intuitive paragraph-level discourse relation prediction model achieves improved performance on PDTB for both implicit discourse relation classification and explicit discourse relation classification.\nAlthough explicit relations are not our focus, predicting an explicit relation will help to reveal the pragmatic roles of its two DUs and reconstruct their representations, which will facilitate predicting neighboring implicit discourse relations that involve one of the DUs.",

        "evidence": "In recent years, the micro-blogging site Twitter has become a major social media platform with hundreds of millions of users. The short (140 character limit), noisy and idiosyncratic nature of tweets make standard information retrieval and data mining methods ill-suited to Twitter. Consequently, there has been an ever growing body of IR and data mining literature focusing on Twitter. However, most of these works employ extensive feature engineering to create task-specific, hand-crafted features. This is time consuming and inefficient as new features need to be engineered for every task.\nIn this paper, we present Tweet2Vec, a method for generating general-purpose vector representation of tweets that can be used for any classification task. Tweet2Vec removes the need for expansive feature engineering and can be used to train any standard off-the-shelf classifier (e.g., logistic regression, svm, etc). Tweet2Vec uses a CNN-LSTM encoder-decoder model that operates at the character level to learn and generate vector representation of tweets. Our method is especially useful for natural language processing tasks on Twitter where it is particularly difficult to engineer features, such as speech-act classification and stance detection (as shown in our previous works on these topics BIBREF0 , BIBREF1 ).\nThere has been several works on generating embeddings for words, most famously Word2Vec by Mikolov et al. BIBREF2 ). There has also been a number of different works that use encoder-decoder models based on long short-term memory (LSTM) BIBREF3 , and gated recurrent neural networks (GRU) BIBREF4 . These methods have been used mostly in the context of machine translation. The encoder maps the sentence from the source language to a vector representation, while the decoder conditions on this encoded vector for translating it to the target language. Perhaps the work most related to ours is the work of Le and Mikolov le2014distributed, where they extended the Word2Vec model to generate representations for sentences (called ParagraphVec). However, these models all function at the word level, making them ill-suited to the extremely noisy and idiosyncratic nature of tweets. Our character-level model, on the other hand, can better deal with the noise and idiosyncrasies in tweets. We plan to make our model and the data used to train it publicly available to be used by other researchers that work with tweets.\nTweet2Vec uses a CNN-LSTM encoderdecoder model that operates at the character level to learn and generate vector representation of tweets.",

He began his career at NBC in 1965 as a general assignment news correspondent, and served as news director at WOR-TV in New York City from 1970 to 1971. He moved to ABC in 1972 and to CBS in 1977, where he worked until his death.\n\nHe was winner of two Emmy Awards, and made the master list of Nixon political opponents for his reporting.\n\nAlthough Lem Tucker's life was brief, his career accomplishments were memorable.\n\nTucker was the first African American elected to the position of student body president at CMU. That election took place when less than one percent of the student body was black. Previous to his election, only one other African American had been elected to a similar position in the United States. While at Central, Tucker was considered one of the university's top forensic students. He served as a chapter president of Pi Kappa Delta, a national speech honorary fraternity.\n\nHe won his first Emmy in 1979 for his coverage of black America and his second in 1983 for a series about hunger in America. While working for the networks, he covered numerous major news events, including the Vietnam War, the Kent State University shootings and the Iran hostage crisis. He covered social unrest and riots in Newark, Miami and Harlem. He also reported from the Woodstock Festival. In 1981, he was covering President Ronald Reagan's speech at the Washington Hilton Hotel and witnessed the shooting of the president. He was broadcasting live reports on CBS Radio within minutes of the incident. He was applauded by his colleagues and others in the media for his continuous and thorough coverage, which he provided well into the next morning.\n\nDuring the course of his career, Tucker returned numerous times to his alma mater to speak to students about politics, share reflections on college life and offer insight regarding work as a national network correspondent.\n\nTucker had a keen sense of humor. In an address given to the CMU community in the early 1980s, he told his audience he was amused to have been asked back to speak at the university, given that during his days as student body president, he \"quibbled a lot\" with the administration. He said, \"How rare for me to be given a microphone and be invited to speak at CMU. Now I am on stage in front of administration and applauded.\"\n\nTucker has one daughter, Linn Carol Tucker.\n\nHis death in 1991 was due to liver failure.",

        "question": "Using examples taken from the text give me a rundown of the primary environments found in Yellowstone National Park.",
        "evidence": "Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.\n\nWhile Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the U.S. Department of the Interior, the first Secretary of the Interior to supervise the park being Columbus Delano. However, the U.S. Army was eventually commissioned to oversee the management of Yellowstone for 30 years between 1886 and 1916. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.\n\nYellowstone National Park spans an area of 3,468.4 sq mi (8,983 km2), comprising lakes, canyons, rivers, and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered a dormant volcano. It has erupted with tremendous force several times in the last two million years. Well over half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.\n\nHundreds of species of mammals, birds, fish, reptiles, and amphibians have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest, and most famous megafauna location in the contiguous United States. Grizzly bears, cougars, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one-third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing, and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.",
        "answer": "Generally considered to be the first national park in the world, Yellowstone National Park is significant in size, covering parts of Wyoming, Montana, and Idaho, and acts as the largest remaining nearly-intact ecosystems.  The park is able to support many types of wildlife including Grizzly bears, cougars, wolves, mountain goats, free-ranging herds of bison and elk, as well as many types of birds and fish, because of the diversity of habitats.  Forests and grasslands dominate some areas of the park, while others offer the completely different experience of mountain ranges, lakes, and rolling prairies.  Some of the park's most unique features are the geysers and hydrothermal features.  In fact, Yellowstone is home to over half of the world's features like these.

These vectors were trained on the corpus obtained from Nepali National Corpus. This pre-lemmatized corpus consists of 14 million words from books, web-texts and news papers. This corpus was mixed with the texts from the dataset before training CBOW and skip-gram version of word2vec using gensim libraryBIBREF24. This trained model consists of vectors for 72782 unique words.\nLight pre-processing was performed on the corpus before training it. For example, invalid characters or characters other than Devanagari were removed but punctuation and numbers were not removed. We set the window context at 10 and the rare words whose count is below 5 are dropped. These word embeddings were not frozen during the training session because fine-tuning word embedding help achieve better performance compared to frozen oneBIBREF20.\nWe have used fasttext embeddings in particular because of its sub-word representation ability, which is very useful in highly inflectional language as shown in Table TABREF25. We have trained the word embedding in such a way that the sub-word size remains between 1 and 4. We particularly chose this size because in Nepali language a single letter can also be a word, for example e, t, C, r, l, n, u and a single character (grapheme) or sub-word can be formed after mixture of dependent vowel signs with consonant letters for example, C + O + = CO, here three different consonant letters form a single sub-word.\nThe two-dimensional visualization of an example word npAl is shown in FIGREF14. Principal Component Analysis (PCA) technique was used to generate this visualization which helps use to analyze the nearest neighbor words of a given sample word. 84 and 104 nearest neighbors were observed using word2vec and fasttext embedding respectively on the same corpus.\nWe have used fasttext embeddings in particular because of its sub-word representation ability, which is very useful in highly inflectional language as shown in Table 3.",

        "evidence": "The ability for a machine to converse with human in a natural and coherent manner is one of challenging goals in AI and natural language understanding. One problem in chat-oriented human-machine dialog system is to reply a message within conversation contexts. Existing methods can be divided into two categories: retrieval-based methods BIBREF0 , BIBREF1 , BIBREF2 and generation based methods BIBREF3 . The former is to rank a list of candidates and select a good response. For the latter, encoder-decoder framework BIBREF3 or statistical translation method BIBREF4 are usually used to generate a response. It is not easy to main the fluency of the generated texts.\nUbuntu dialogue corpus BIBREF5 is the public largest unstructured multi-turns dialogue corpus which consists of about one-million two-person conversations. The size of the corpus makes it attractive for the exploration of deep neural network modeling in the context of dialogue systems. Most deep neural networks use word embedding as the first layer. They either use fixed pre-trained word embedding vectors generated on a large text corpus or learn word embedding for the specific task. The former is lack of flexibility of domain adaptation. The latter requires a very large training corpus and significantly increases model training time. Word out-of-vocabulary issue occurs for both cases. Ubuntu dialogue corpus also contains many technical words (e.g. “ctrl+alt+f1\", “/dev/sdb1\"). The ubuntu corpus (V2) contains 823057 unique tokens whereas only 22% tokens occur in the pre-built GloVe word vectors. Although character-level representation which models sub-word morphologies can alleviate this problem to some extent BIBREF6 , BIBREF7 , BIBREF8 , character-level representation still have limitations: learn only morphological and orthographic similarity, other than semantic similarity (e.g. `car' and `bmw') and it cannot be applied to Asian languages (e.g. Chinese characters).\nIn this paper, we generate word embedding vectors on the training corpus based on word2vec BIBREF9 . Then we propose an algorithm to combine the generated one with the pre-trained word embedding vectors on a large general text corpus based on vector concatenation. The new word representation maintains information learned from both general text corpus and task-domain. The nice property of the algorithm is simplicity and little extra computational cost will be added. It can address word out-of-vocabulary issue effectively. This method can be applied to most NLP deep neural network models and is language-independent. We integrated our methods with ESIM(baseline model) BIBREF10 . The experimental results have shown that the proposed method has significantly improved the performance of original ESIM model and obtained state-of-the-art results on both Ubuntu Dialogue Corpus and Douban Conversation Corpus BIBREF11 . On Ubuntu Dialogue Corpus (V2), the improvement to the previous best baseline model (single) on INLINEFORM0 is 3.8% and our ensemble model on INLINEFORM1 is 75.9%. On Douban Conversation Corpus, the improvement to the previous best model (single) on INLINEFORM2 is 3.6%.\nOur contributions in this paper are summarized below:\nThe rest paper is organized as follows. In Section SECREF2 , we review the related work. In Section SECREF3 we provide an overview of ESIM (baseline) model and describe our methods to address out-of-vocabulary issues. In Section SECREF4 , we conduct extensive experiments to show the effectiveness of the proposed method. Finally we conclude with remarks and summarize our findings and outline future research directions.\nThe experimental results have shown that the proposed method has significantly improved the performance of original ESIM model and obtained state-of-the-art results on both Ubuntu Dialogue Corpus and Douban Conversation Corpus.",

Our approach is an extension of BIBREF2 , in which only an term is added with intent-type tags associated to this sentence final token, both for LSTM and Bi-LSTM cases. However, we experimented with adding both and terms as Bi-LSTMs will be used for seq2seq learning, and we observed that slightly better results can be achieved by doing so. The idea behind is that, since this is a seq2seq learning problem, at the last time step (i.e., prediction at ) the reverse pass in Bi-LSTM would be incomplete (refer to Fig. FIGREF24 (a) to observe the last Bi-LSTM cell). Therefore, adding token and leveraging the backward LSTM output at first time step (i.e., prediction at ) would potentially help for joint seq2seq learning.

This shows that the model learned with zero-shot can roughly identify the answer spans in context but less accurate. In row (c), we fine-tuned a BERT model pre-trained on English monolingual corpus (English BERT) on Chinese RC training data directly by appending fastText-initialized Chinese word embeddings to the original word embeddings of English-BERT. Its F1 score is even lower than that of zero-shot transferring multi-BERT (rows (c) v.s. (e)). The result implies multi-BERT does acquire better cross-lingual capability through pre-training on multilingual corpus. Table TABREF8 shows the results of multi-BERT fine-tuned on different languages and then tested on English , Chinese and Korean. The top half of the table shows the results of training data without translation. It is not surprising that when the training and testing sets are in the same language, the best results are achieved, and multi-BERT shows transfer capability when training and testing sets are in different languages, especially between Chinese and Korean.\nIn the lower half of Table TABREF8, the results are obtained by the translated training data. First, we found that when testing on English and Chinese, translation always degrades the performance (En v.s. En-XX, Zh v.s. Zh-XX). Even though we translate the training data into the same language as testing data, using the untranslated data still yield better results. For example, when testing on English, the F1 score of the model training on Chinese (Zh) is 53.8, while the F1 score is only 44.1 for the model training on Zh-En. This shows that translation degrades the quality of data. There are some exceptions when testing on Korean. Translating the English training data into Chinese, Japanese and Korean still improve the performance on Korean. We also found that when translated into the same language, the English training data is always better than the Chinese data (En-XX v.s. Zh-XX), with only one exception (En-Fr v.s. Zh-Fr when testing on KorQuAD). This may be because we have less Chinese training data than English. These results show that the quality and the size of dataset are much more important than whether the training and testing are in the same language or not.\nIt is not surprising that when the training and testing sets are in the same language, the best results are achieved, and multi-BERT shows transfer capability when training and testing sets are in different languages, especially between Chinese and Korean.",

Thought to be a mutant clone of the Pinot Noir variety, it normally has a grayish-blue fruit, accounting for its name, but the grapes can have a brownish pink to black and even white appearance. The word pinot could have been given to it because the grapes grow in small pinecone-shaped clusters. The wines produced from this grape also vary in color from a deep golden yellow to copper and even a light shade of pink, and it is one of the more popular grapes for skin-contact wine.\n\nPinot Gris is grown around the globe, with the \"spicy\" full-bodied Alsatian and lighter-bodied, more acidic Italian styles being most widely recognized. The Alsatian style, often duplicated in New World wine regions such as Marlborough, Tasmania, South Australia, Washington, Oregon, and South Africa tend to have moderate to low acidity, higher alcohol levels and an almost \"oily\" texture that contributes to the full-bodied nature of the wine. The flavors can range from ripe tropical fruit notes of melon and mango to some botrytis-influenced flavors. In Italy, Pinot grigio grapes are often harvested early to retain the refreshing acidity and minimize some of the overt-fruitiness of the variety, creating a more neutral flavor profile. This style is often imitated in other Old World wine regions, such as Germany, where the grape is known as Ruländer, or more commonly, Grauburgunder.",

We apply a naive Bayesian classifier with character (2, 4 & 6)-grams, word unigram and word bigram features with a hierarchical lexicon based classifier.\nThe naive Bayesian classifier is trained to predict the specific language label of a piece of text, but used to first classify text as belonging to either the Nguni family, the Sotho family, English, Afrikaans, Xitsonga or Tshivenda. The scikit-learn multinomial naive Bayes classifier is used for the implementation with an alpha smoothing value of 0.01 and hashed text features.\nThe lexicon based classifier is then used to predict the specific language within a language group. For the South African languages this is done for the Nguni and Sotho groups. If the lexicon prediction of the specific language has high confidence then its result is used as the final label else the naive Bayesian classifier's specific language prediction is used as the final result. The lexicon is built over all the data and therefore includes the vocabulary from both the training and testing sets.\nThe lexicon based classifier is designed to trade higher precision for lower recall. The proposed implementation is considered confident if the number of words from the winning language is at least one more than the number of words considered to be from the language scored in second place.\nThe stacked classifier is tested against three public LID implementations BIBREF17, BIBREF23, BIBREF8. The LID implementation described in BIBREF17 is available on GitHub and is trained and tested according to a post on the fasttext blog. Character (5-6)-gram features with 16 dimensional vectors worked the best. The implementation discussed in BIBREF23 is available from https://github.com/tomkocmi/LanideNN.

        "question": "What are the earliest records of dried fruits in history?",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

        "evidence": "Detection: In hypernymy detection, the task is to classify whether pairs of words are in a hypernymy relation. For this task, we evaluate all models on five benchmark datasets: First, we employ the noun-noun subset of bless, which contains hypernymy annotations for 200 concrete, mostly unambiguous nouns. Negative pairs contain a mixture of co-hyponymy, meronymy, and random pairs. This version contains 14,542 total pairs with 1,337 positive examples. Second, we evaluate on leds BIBREF13 , which consists of 2,770 noun pairs balanced between positive hypernymy examples, and randomly shuffled negative pairs. We also consider eval BIBREF14 , containing 7,378 pairs in a mixture of hypernymy, synonymy, antonymy, meronymy, and adjectival relations. eval is notable for its absence of random pairs. The largest dataset is shwartz BIBREF2 , which was collected from a mixture of WordNet, DBPedia, and other resources. We limit ourselves to a 52,578 pair subset excluding multiword expressions. Finally, we evaluate on wbless BIBREF15 , a 1,668 pair subset of bless, with negative pairs being selected from co-hyponymy, random, and hyponymy relations. Previous work has used different metrics for evaluating on BLESS BIBREF11 , BIBREF5 , BIBREF6 . We chose to evaluate the global ranking using Average Precision. This allowed us to use the same metric on all detection benchmarks, and is consistent with evaluations in BIBREF4 .\nDirection: In direction prediction, the task is to identify which term is broader in a given pair of words. For this task, we evaluate all models on three datasets described by BIBREF16 : On bless, the task is to predict the direction for all 1337 positive pairs in the dataset. Pairs are only counted correct if the hypernymy direction scores higher than the reverse direction, i.e. INLINEFORM0 . We reserve 10% of the data for validation, and test on the remaining 90%. On wbless, we follow prior work BIBREF17 , BIBREF18 and perform 1000 random iterations in which 2% of the data is used as a validation set to learn a classification threshold, and test on the remainder of the data. We report average accuracy across all iterations. Finally, we evaluate on bibless BIBREF16 , a variant of wbless with hypernymy and hyponymy pairs explicitly annotated for their direction. Since this task requires three-way classification (hypernymy, hyponymy, and other), we perform two-stage classification. First, a threshold is tuned using 2% of the data, identifying whether a pair exhibits hypernymy in either direction. Second, the relative comparison of scores determines which direction is predicted. As with wbless, we report the average accuracy over 1000 iterations.\nGraded Entailment: In graded entailment, the task is to quantify the degree to which a hypernymy relation holds. For this task, we follow prior work BIBREF19 , BIBREF18 and use the noun part of hyperlex BIBREF20 , consisting of 2,163 noun pairs which are annotated to what degree INLINEFORM0 is-a INLINEFORM1 holds on a scale of INLINEFORM2 . For all models, we report Spearman's rank correlation INLINEFORM3 . We handle out-of-vocabulary (OOV) words by assigning the median of the scores (computed across the training set) to pairs with OOV words.\nDetection: In hypernymy detection, the task is to classify whether pairs of words are in a hypernymy relation.\nDirection: In direction prediction, the task is to identify which term is broader in a given pair of words.\nGraded Entailment: In graded entailment, the task is to quantify the degree to which a hypernymy relation holds.",

Sentiment analysis determines the polarisation of the text. It answers the question as to whether a particular text is a positive, negative, or neutral one.\nOur goal is to build a comprehensive set of techniques for preparing and analysing texts containing opinions and generating user-friendly descriptive reports in natural language - Figure FIGREF1 . In this paper, we describe briefly the whole workflow and present a prototype implementation. Currently, existing solutions for sentiment annotation offer mostly analysis on the level of entire documents, and if you go deeper to the level of individual product features, they are only superficial and poorly prepared for the analysis of large volumes of data. This can especially be seen in scientific articles where the analysis is carried out on a few hundred reviews only. It is worth mentioning that this task is extremely problematic because of the huge diversity of languages and the difficulty of building a single solution that can cover all the languages used in the world. Natural language analysis often requires additional pre-processing steps, especially at the stage of preparing the data for analysis, and steps specific for each language. Large differences can be seen in the analysis of the Polish language (a highly inflected language) and English (a grammatically simpler one). We propose a solution that will cover several languages, however in this prototype implementation we focused on English texts only.\nIn this paper, we present analysis and workflow inspired by the work of Joty, Carenini and Ng BIBREF0 . We experimented with several methods in order to validate aspect-based sentiment analysis approaches and in the next steps we want to customise our implementation for the Polish language.\nThe paper presents in Section SECREF1 an introduction to sentiment analysis and its importance in business, then in Section SECREF2 - related work from rhetorical and sentiment analysis areas is presented. Section SECREF3 covers description of our method. Implementation and the dataset are described in Section SECREF4 . Section SECREF5 refers to the results. The last Section SECREF6 consists of conclusions and future work.\nOur goal is to build a comprehensive set of techniques for preparing and analysing texts containing opinions and generating user-friendly descriptive reports in natural language - Figure FIGREF1 .",

        "evidence": "Several efficient algorithms for simple random sampling have been developed. A naive algorithm is the draw-by-draw algorithm where at each step we remove the item at that step from the set with equal probability and put the item in the sample. We continue until we have sample of desired size \n�\nk. The drawback of this method is that it requires random access in the set.\n\nThe selection-rejection algorithm developed by Fan et al. in 1962 requires a single pass over data; however, it is a sequential algorithm and requires knowledge of total count of items \n�\nn, which is not available in streaming scenarios.\n\nA very simple random sort algorithm was proved by Sunter in 1977. The algorithm simply assigns a random number drawn from uniform distribution \n(\n0\n,\n1\n)\n(0,1) as a key to each item, then sorts all items using the key and selects the smallest \n�\nk items.\n\nJ. Vitter in 1985 proposed reservoir sampling algorithms, which are widely used. This algorithm does not require knowledge of the size of the population \n�\nn in advance, and uses constant space.\n\nRandom sampling can also be accelerated by sampling from the distribution of gaps between samples and skipping over the gaps.",

        "evidence": "State-of-the-art (SOTA) artificial neural networks (ANNs) achieve impressive results in a variety of machine intelligence tasks. However, they largely rely on mechanisms that diverge from the original inspiration from biological neural networks. As a result, only a small part of this prolific field also contributes to computational neuroscience. In fact, this biological implausibility is also an important issue for machine intelligence. For their impressive performance, ANNs trade off other desired properties, which are present in biological systems. For example, ANN training often demands very large and labelled datasets. When labels are unavailable, self-supervised learning schemes exist, where supervisory error signals generated by the network itself are exploited and backpropagated from the output towards the input to update the network's parameters. However, this global propagation of signals in deep networks introduces another limitation. Namely, it prevents the implementation of efficient distributed computing hardware that would be based on only local signals from neighbouring physical nodes in the network, and is in contrast to local synaptic plasticity rules that partly govern biological learning. Several pieces of work have been addressing parts of the biological implausibility and hardware-inefficiency of backpropagation in ANNs. such as the need for exactly symmetric forward and backward weights or the waiting time caused by the network's forward-backward pass between two training updates in a layer (weight transport and update-locking problems). Recently, an approximation to backpropagation that is mostly Hebbian, i.e. relies on mostly pre-and post-synaptic activity of each synapse, has been achieved by reducing the global error requirements to 1-bit information. Two schemes that further localize the signal that is required for a weight update are Equilibrium Propagation and Predictive Coding. Both methods approximate backpropagation through Hebbian-like learning, by delegating the global aspect of the computation, from a global error signal, to a global convergence of the network state to an equilibrium. This equilibrium is reached through several iterative steps of feed-forward and feed-back communication throughout the network, before the ultimate weight update by one training example. The biological plausibility and hardware-efficiency of this added iterative process of signal propagation are open questions that begin to be addressed.\nMoreover, learning through backpropagation, and presumably also its approximations, has another indication of biological implausibility, which also significantly limits ANN applicability. Namely, it produces networks that are confused by small adversarial perturbations of the input, which are imperceptible by humans. It has recently been proposed that a defence strategy of \"deflection\" of adversarial attacks may be the ultimate solution to that problem. Through this strategy, to cause confusion in the network's inferred class, the adversary is forced to generate such a changed input that really belongs to the distribution of a different input class. Intuitively, but also strictly by definition, this deflection is achieved if a human assigns to the perturbed input the same label that the network does. Deflection of adversarial attacks in ANNs has been demonstrated by an elaborate scheme that is based on detecting the attacks. However, the human ability to deflect adversarial perturbations likely does not rely on detecting them, but rather on effectively ignoring them, making the deflecting type of robustness an emergent property of biological computation rather than a defence mechanism. The biological principles that underlie this property of robustness are unclear, but it might emerge from the distinct algorithms that govern learning in the brain.\nTherefore, what is missing is a biologically plausible model that can learn from fewer data-points, without labels, through local plasticity, and without feedback from distant layers. This model could then be tested for emergent adversarial robustness. A good candidate category of biological networks and learning algorithms is that of competitive learning. Neurons that compete for their activation through lateral inhibition are a common connectivity pattern in the superficial layers of the cerebral cortex). This pattern is described as winner-take-all (WTA), because competition suppresses activity of weakly activated neurons, and emphasizes strong ones. Combined with Hebbian-like plasticity rules, WTA connectivity gives rise to competitivelearning algorithms. These networks and learning schemes have been long studied (Von der and a large literature based on simulations and analyses describes their functional properties. A WTA neuronal layer, depending on its specifics, can restore missing input signals, perform decision making i.e. winner selection, and generate oscillations such as those that underlie brain rhythms. Perhaps more importantly, its neurons can learn to become selective to different input patterns, such as orientation of visual bars in models of the primary visual cortex (Von der, MNIST handwritten digits, CIFAR10 objects, spatiotemporal spiking patterns, and can adapt dynamically to model changing objects. The WTA model is indeed biologically plausible, Hebbian plasticity is local, and learning is input-driven, relying on only feed-forward communication of neurons -properties that seem to address several of the limitations of ANNs. However, the model's applicability is limited to simple tasks. That is partly because the related theoretical literature remains surprisingly unsettled, despite its long history, and the strong and productive community interest. described a very related theory but for a model that is largely incompatible with ANNs and thus less practical. It uses spiking and stochastic neurons, input has to be discretized, and each input feature must be encoded through multiple binary neurons. Moreover, it was only proven for neurons with an exponential activation function. It remains therefore unclear which specific plasticity rule and structure could optimize an ANN WTA for Bayesian inference. It is also unclear how to minimize a common loss function such as cross-entropy despite unsupervised learning, and how a WTA could represent varying families of probability distributions. In summary, on the theoretical side, an algorithm that is simultaneously normative, based on WTA networks and Hebbian unsupervised plasticity, performs Bayesian inference, and, importantly, is composed of conventional, i.e. non-spiking, ANN elements and is rigorously linked to modern ANN tools such as cross-entropy loss, would be an important advance but has been missing. On the practical side, evidence that Hebbian WTA networks could be useful for presently pertinent issues of modern ANNs such as adversarial robustness, generation of synthetic images, or faster learning, has remained limited. Here we aim to fill these gaps. Recently, when WTA networks were studied in a theoretical framework compatible with conventional machine learning (ML), but in the context of short-term as opposed to long-term Hebbian plasticity, it resulted in surprising practical advantages over supervised ANNs. A similar theoretical approach could also reveal unknown advantages of long-term Hebbian plasticity in WTA networks. In addition, it could provide insights into how a WTA microcircuit could participate in larger-scale computation by deeper cortical or artificial networks.\nHere we construct \"SoftHebb\", a biologically plausible WTA model that is based on standard ratebased neurons as in ANNs, can accommodate various activation functions, and learns without labels, using local plasticity and only feed-forward communication, i.e. the properties we seek in an ANN. Importantly, it is equipped with a simple normalization of the layer's activations, and an optional temperature-scaling mechanism, producing a soft WTA instead of selecting a single \"hard\" winner neuron. This allows us to prove formally that a SoftHebb layer is a generative mixture model that objectively minimizes its Kullback-Leibler (KL) divergence from the input distribution through Bayesian inference, thus providing a new formal ML-theoretic perspective of these networks. We complement our main results, which are theoretical, with experiments that are small-scale but produce intriguing results. As a generative model, SoftHebb has a broader scope than classification, but we test it on image classification tasks. Surprisingly, in addition to overcoming several inefficiencies of backpropagation, the unsupervised WTA model also outperforms a supervised two-layer perceptron in several aspects: learning speed and accuracy in the first presentation of the training dataset, robustness to noisy data and to one of the strongest white-box adversarial attacks, i.e. projected gradient descent (PGD), and without any explicit defence. Interestingly, the SoftHebb model also exhibits inherent properties of deflection of the adversarial attacks, and generates object interpolations.\nHowever, the human ability to deflect adversarial perturbations likely does not rely on detecting them, but rather on effectively ignoring them, making the deflecting type of robustness an emergent property of biological computation rather than a defence mechanism.",

They can answer each question with either `yes', `rather yes', `rather no', or `no'. They can supplement each answer with a comment of at most 500 characters.\nThe questions asked on Smartvote have been edited by a team of political scientists. They are intended to cover a broad range of political issues relevant at the time of the election. A detailed documentation of the design of Smartvote and the editing process of the questions is provided by BIBREF12.\nWe merged the two labels on each pole into a single label: `yes' and `rather yes' were combined into `favor'; `rather no', or `no' into `against`. This improves the consistency of the data and the comparability to previous stance detection datasets.\nWe did not further preprocess the text of the comments.\nAs the API does not provide the language of comments, we employed a language identifier to automatically annotate this information. We used the langdetect library BIBREF13. For each responder we classified all the comments jointly, assuming that responders did not switch code during the answering of the questionnaire.\nWe applied the identifier in a two-step approach. In the first run we allowed the identifier to output all 55 languages that it supports out of the box, plus Romansh, the fourth official language in Switzerland. We found that no Romansh comments were detected and that all unexpected outputs were misclassifications of German, French or Italian comments. We further concluded that little or no Swiss German comments are in the dataset: If they were, some of them would have manifested themselves in the form of misclassifications (e.g. as Dutch).\nIn the second run, drawing from these conclusions, we restricted the identifier's output to English, French, German and Italian.\nWe pre-filtered the questions and answers to improve the quality of the dataset.

Therefore, all questions and corresponding answers pertaining to national elections were included.\nIn the context of communal and cantonal elections, candidates have answered both local questions and a subset of the national questions. Of those elections, we only considered answers to the questions that also had been asked in a national election. Furthermore, they were only used to augment the training set while the validation and test sets were restricted to answers from national elections.\nWe discarded the less than 20 comments classified as English. Furthermore, instances that met any of the following conditions were filtered from the dataset:\nQuestion is not a closed question or does not address a clearly defined political issue.\nNo comment was submitted by the candidate or the comment is shorter than 50 characters.\nComment starts with “but” or a similar indicator that the comment is not a self-contained statement.\nComment contains a URL.\nIn total, a fifth of the original comments were filtered out.\nThe questions have been organized by the Smartvote editors into categories (such as “Economy”). We further consolidated the pre-defined categories into 12 broad topics (Table TABREF7).\nThe dataset is shared under a CC BY-NC 4.0 license. Copyright remains with www.smartvote.ch.\nGiven the sensitive nature of the data, we increase the anonymity of the data by hashing the respondents' IDs. No personal attributes of the respondents, such as their party affiliation, are included in the dataset.

Taiyaki which was famous in Japan became Bungeoppang. In Japanese, \"Tai\" means sea bream, and \"yaki\" means roasted. So this is a cheap street snack which imitates the more expensive Japanese food. It was the most common street food in the 1950s and 1960s, after the Japanese colonial period. It has appeared again since the 1990s.\tBoong o bbang.jpg\nEomuk\tFish cake is a mixture of fish meat and wheat flour. The hot sauce flavored with soy sauce can be addictive to many. Eomuk is also a typical Japanese food. It used to be called oden; Japanese oden is boiled tofu, fish cake, konjac, jelly, and boiled egg on a skewer. It was after the time of enlightenment in 1876 that the eomuk tang (fish cake soup) was brought to Korea. It entered Korea at the port of Bu-san and became a widespread Korean street food. As the home of fish cake history, Busan boasts that its fish cake is the best in Korea.\tEomuk-kkochi.jpg\nHotteok\tHotteok is a traditional street food in South Korea.

On the restaurants dataset, this corresponds to an absolute improvement of $2.2\\%$ compared to the previous state-of-the-art method BERT-PT. Language model finetuning produces a larger improvement on the restaurants dataset. We think that one reason for that might be that the restaurants domain is underrepresented in the pre-training corpora of BERTBASE. Generally, we find that language model finetuning helps even if the finetuning domain does not match the evaluation domain. We think the reason for this might be that the BERT-base model is pre-trained more on knowledge-based corpora like Wikipedia than on text containing opinions. Another finding is that BERT-ADA Joint performs better on the laptops dataset than BERT-ADA Rest, although the unique amount of laptop reviews are the same in laptops- and joint-corpora. We think that confusion can be created when mixing the domains, but this needs to be investigated further. We also find that the XLNet-base baseline performs generally stronger than BERT-base and even outperforms BERT-ADA Lapt with an accuracy of $79.89\\%$ on the laptops dataset.\nIn general, the ATSC task generalizes well cross-domain, with about 2-$3\\%$ drop in accuracy compared to in-domain training.

        "answer": "Over-translation and under-translation.",
        "evidence": "Recently, neural machine translation (NMT) has gained popularity in the field of machine translation. The conventional encoder-decoder NMT proposed by Cho2014 uses two recurrent neural networks (RNN): one is an encoder, which encodes a source sequence into a fixed-length vector, and the other is a decoder, which decodes the vector into a target sequence. A newly proposed attention-based NMT by DzmitryBahdana2014 can predict output words using the weights of each hidden state of the encoder by the attention mechanism, improving the adequacy of translation.\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu2016 argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated. This is due to the fact that NMT can not completely convert the information from the source sentence to the target sentence. Mi2016a and Feng2016 pointed out that NMT lacks the notion of coverage vector in phrase-based statistical machine translation (PBSMT), so unless otherwise specified, there is no way to prevent missing translations.\nAnother problem in NMT is an objective function. NMT is optimized by cross-entropy; therefore, it does not directly maximize the translation accuracy. Shen2016 pointed out that optimization by cross-entropy is not appropriate and proposed a method of optimization based on a translation accuracy score, such as expected BLEU, which led to improvement of translation accuracy. However, BLEU is an evaluation metric based on n-gram precision; therefore, repetition of some words may be present in the translation even though the BLEU score is improved.\nTo address to problem of repeating and missing words in the translation, tu2016neural introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences. In their method, after training the forward translation in a manner similar to the conventional attention-based NMT, they train a back-translation model from the hidden state of the decoder into the source sequence by a new decoder to enforce agreement between source and target sentences.\nIn order to confirm the language independence of the framework, we experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoder-reconstructor. Our experiments show that their method offers significant improvement in BLEU scores and alleviates the problem of repeating and missing words in the translation on English-Japanese translation task, though the difference is not significant on Japanese-English translation task.\nIn addition, we jointly train a model of forward translation and back-translation without pre-training, and then evaluate this model. As a result, the encoder-decoder-reconstructor can not be trained well without pre-training, so it proves that we have to train the forward translation model in a manner similar to the conventional attention-based NMT as pre-training.\nThe main contributions of this paper are as follows:\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu et al. (2016) argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated.",

        "evidence": "",
        "answer": "The divide and average method for computing square roots starts with a guess of the square root. For example, to compute the square root of 8, we might start with 3, since we know 9 is the square of 3. Given a guess, the method is a formula for generating the next guess. The formula states the next guess should be average of the current guess and the square (the number for which you want compute the square root) divided by the guess. Returning to our example, the next guess is (3 + 8/3)/2 = 17/6. Applying this formula repeatedly yields a guess which is closer and closer to actual square root.\n\nThe reason this works is that limit of the sequence of guesses generated by this formula is the square root. To see this, first recognize that in the limit, next guess must be equal to the current guess. The guesses get closer and closer until, after an infinite number of steps, they are the same. Using a variable X to represent the limit and applying the formula yields an equation which can be solved for X via algebra. The solution is that X must be square root.",

The pawn structure needs to be aligned in a way that protects the king at all times and clears the way for the queen to strategically advance forward into the opponent's side. Another strategy is by making the move of casting that pushes the king to the corner as opposed to being exposed in the front once pawns are taken out.",

The alliance of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, led respectively by King Władysław II Jagiełło (Jogaila), and Grand Duke Vytautas, decisively defeated the German Teutonic Order, led by Grand Master Ulrich von Jungingen. Most of the Teutonic Order's leadership were killed or taken prisoner.\n\nAlthough defeated, the Teutonic Order withstood the subsequent siege of the Malbork Castle and suffered minimal territorial losses at the Peace of Thorn (1411), with other territorial disputes continuing until the Treaty of Melno in 1422. The order, however, never recovered their former power, and the financial burden of war reparations caused internal conflicts and an economic downturn in the lands controlled by them. The battle shifted the balance of power in Central and Eastern Europe and marked the rise of the Polish–Lithuanian union as the dominant regional political and military force.\n\nThe battle was one of the largest in medieval Europe. The battle is viewed as one of the most important victories in the histories of Poland and Lithuania. It is also commemorated in Ukraine and Belarus. It has been used as a source of romantic legends and national pride, becoming a larger symbol of struggle against foreign invaders.

We conducted a feature ablation study by holding out (sans) each feature group and training and testing the support vector model using a linear kernel and 5-fold, stratified cross-validation. We report the average F1-score from our baseline approach (all feature groups) and report the point difference (+ or -) in F1-score performance observed by ablating each feature set.\nBy ablating each feature group from the full dataset, we observed the following count of features - sans lexical: 185, sans syntactic: 16,935, sans emotion: 16,954, sans demographics: 16,946, sans sentiment: 16,950, sans personality: 16,946, and sans LIWC: 16,832. In Figure 1, compared to the baseline performance, significant drops in F1-scores resulted from sans lexical for depressed mood (-35 points), disturbed sleep (-43 points), and depressive symptoms (-45 points). Less extensive drops also occurred for evidence of depression (-14 points) and fatigue or loss of energy (-3 points). In contrast, a 3 point gain in F1-score was observed for no evidence of depression. We also observed notable drops in F1-scores for disturbed sleep by ablating demographics (-7 points), emotion (-5 points), and sentiment (-5 points) features. These F1-score drops were accompanied by drops in both recall and precision. We found equal or higher F1-scores by removing non-lexical feature groups for no evidence of depression (0-1 points), evidence of depression (0-1 points), and depressive symptoms (2 points).\nUnsurprisingly, lexical features (unigrams) were the largest contributor to feature counts in the dataset. We observed that lexical features are also critical for identifying depressive symptoms, specifically for depressed mood and for disturbed sleep. For the classes higher in the hierarchy - no evidence of depression, evidence of depression, and depressive symptoms - the classifier produced consistent F1-scores, even slightly above the baseline for depressive symptoms and minor fluctuations of change in recall and precision when removing other feature groups suggesting that the contribution of non-lexical features to classification performance was limited. However, notable changes in F1-score were observed for the classes lower in the hierarchy including disturbed sleep and fatigue or loss of energy. For instance, changes in F1-scores driven by both recall and precision were observed for disturbed sleep by ablating demographics, emotion, and sentiment features, suggesting that age or gender (“mid-semester exams have me restless”), polarity and subjective terms (“lack of sleep is killing me”), and emoticons (“wide awake :(”) could be important for both identifying and correctly classifying a subset of these tweets.\nUnsurprisingly, lexical features (unigrams) were the largest contributor to feature counts in the dataset.",

In these networks, word embedding vectors are fed as input to overcome the data sparsity problem and make the representations of words more “meaningful” and robust. Those embeddings indicate how close the words are to each other in the vector space model (VSM).\nMost of the studies utilise embeddings, such as word2vec BIBREF1, which take into account the syntactic and semantic representations of the words only. Discarding the sentimental aspects of words may lead to words of different polarities being close to each other in the VSM, if they share similar semantic and syntactic features.\nFor Turkish, there are only a few studies which leverage sentimental information in generating the word and document embeddings. Unlike the studies conducted for English and other widely-spoken languages, in this paper, we use the official dictionaries for this language and combine the unsupervised and supervised scores to generate a unified score for each dimension of the word embeddings in this task.\nOur main contribution is to create original and effective word vectors that capture syntactic, semantic, and sentimental characteristics of words, and use all of this knowledge in generating embeddings. We also utilise the word2vec embeddings trained on a large corpus. Besides using these word embeddings, we also generate hand-crafted features on a review basis and create document vectors. We evaluate those embeddings on two datasets. The results show that we outperform the approaches which do not take into account the sentimental information. We also had better performances than other studies carried out on sentiment analysis in Turkish media. We also evaluated our novel embedding approaches on two English corpora of different genres. We outperformed the baseline approaches for this language as well. The source code and datasets are publicly available.\nThe paper is organised as follows. In Section 2, we present the existing works on sentiment classification. In Section 3, we describe the methods proposed in this work. The experimental results are shown and the main contributions of our proposed approach are discussed in Section 4. In Section 5, we conclude the paper.\nFor Turkish, there are only a few studies which leverage sentimental information in generating the word and document embeddings.

        "question": "Extract from the following passage research related to electricity in the 17th and 18th centuries.",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

Given a Wikipedia article written in English, we have pre-processed the textual part through the Tanl pipeline. Similar to what described in Section \"Reference dictionary\" for the reference dictionary, we have first divided the text in sentences and the sentences into single word forms. For each form, we have considered the lemma (when available) and the part of speech (POS). For instance, starting from an example sentence extracted from the Wikipedia page on the Alzheimer's disease: “Other risk factors include a history of head injuries, depression, or hypertension.\", we have obtained the annotation shown in Figure 4 .\nAs in the case of the dictionary, each word in the text has been lowercasing.\nAfter pre-processing the text of each article, we have attempted to match each n-gram (with n between 1 and 10) in the corpus with the entries in the extended dictionary. We both attempt an exact match and an approximate match, the latter removing prepositions, punctuations and articles from the n-grams. Approximate matching leads to several advantages. Indeed, exploiting the text pre-processing allows to identify dictionary definitions present in the text, even when the number differs. As an example, the dictionary definition “injury\" will match with “injuries\", mentioned in the text, because in the approximation one can consider the lemmas. Further, considering the POS allows to identify mentions when interleaved by prepositions, articles, and conjunctions that change the form but do not alter the meaning. As an example, the approximate definition “aneurysm vein galen” will match also with the following n-gram: “the aneurysm and vein of galen\", if present in the text.\nWe have extracted the bio-medical entities present in the Wikipedia medical articles through a n-gram-based technique.",

The then-designated A3XX project was presented in 1994; Airbus launched the €9.5 billion ($10.7 billion) A380 programme on 19 December 2000. The first prototype was unveiled in Toulouse on 18 January 2005, with its first flight on 27 April 2005. It then obtained its type certificate from the European Aviation Safety Agency (EASA) and the US Federal Aviation Administration (FAA) on 12 December 2006.\n\nDue to difficulties with the electrical wiring, the initial production was delayed by two years and the development costs almost doubled. It was first delivered to Singapore Airlines on 15 October 2007 and entered service on 25 October. Production peaked at 30 per year in 2012 and 2014. However, after the largest customer, Emirates, reduced its last order in February 2019, Airbus announced that A380 production would end in 2021.

        "answer": "Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets. Remote sensing is used in numerous fields, including geophysics, geography, land surveying and most Earth science disciplines (e.g. exploration geophysics, hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others.\n\nIn current usage, the term remote sensing generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into \"active\" remote sensing (when a signal is emitted by a satellite or aircraft to the object and its reflection detected by the sensor) and \"passive\" remote sensing (when the reflection of sunlight is detected by the sensor).",

        "evidence": "Negotiations, either between individuals or entities, are ubiquitous in everyday human interactions ranging from sales to legal proceedings. Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nAlthough there have been attempts to gain insights into negotiations, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section  2).",

The bulk of production was from the dominant Staffordshire pottery industry. America was a major market for English transfer-printed wares, whose imagery was adapted to the American market; several makers made this almost exclusively.\n\nThe technique was essential for adding complex decoration such as the Willow pattern to relatively cheap pottery. In particular, transfer printing brought the price of a matching dinner service low enough for large numbers of people to afford.\n\nApart from pottery, the technique was used on metal, and enamelled metal, and sometimes on wood and textiles.

For example, suppose your mind is filled with greed, evil thoughts like harming another person, and jealousy. In that case, it reflects restlessness as we will never be satisfied, punishments for harming another person, and stress to become like someone else, respectively. For a positive example, a life lived with generosity, righteousness, kindness, and genuinely putting good out there will lead to respect in society and a fulfilled life.

        "evidence": "World War I was fought on many fronts around the world from the battlefields of Europe to the far-flung colonies in the Pacific and Africa. While it is most famous for the trench warfare stalemate that existed on Europe's Western Front, in other theatres of combat the fighting was mobile and often involved set-piece battles and cavalry charges. The Eastern Front often took thousands of casualties a day during the major offensive pushes, but it was the West that saw the most concentrated slaughter. It was in the west that the newly industrialized world powers could focus their end products on the military–industrial complex. The deadliest day of the war was during the opening days of the conflict. The Imperial German war council had initiated the Schlieffen Plan which involved multiple armies flooding through the borders of Belgium and France. On August 22, 1914, during the Battle of the Frontiers, five separate French armies engaged the German invaders independently of each other. Across all those battlefields, on that single day, 27,000 French soldiers lost their lives protecting their country.",

While World War I is known primarily for trench warfare, it also involved mobile combat and the movement of tens of thousands of men, machines, and animals. There were numerous, bloody days and battles in World War I, but the most deadly took place during the opening days of the conflict, at the Battle of Frontiers, where 27,000 French soldiers were killed in a single day.",

Table presents the results for bilingual UWS and multilingual leveraging. For the former, we reach our best result by using as aligned information the French, the original aligned language for this dataset. Languages closely related to French (Spanish and Portuguese) ranked better, while our worst result used German. English also performs notably well in our experiments. We believe this is due to the statistics features of the resulting text. We observe in Table that the English portion of the dataset contains the smallest vocabulary among all languages. Since we train our systems in very low-resource settings, vocabulary-related features can impact greatly the system's capacity to language-model, and consequently the final quality of the produced alignments. Even in high-resource settings, it was already attested that some languages are more difficult to model than others BIBREF9.\nFor the multilingual selection experiments, we experimented combining the languages from top to bottom as they appear Table (ranked by performance; e.g. 1-3 means the combination of FR(1), EN(2) and PT(3)). We observe that the performance improvement is smaller than the one observed in previous work BIBREF10, which we attribute to the fact that our dataset was artificially augmented. This could result in the available multilingual form of supervision not being as rich as in a manually generated dataset. Finally, the best boundary segmentation result is obtained by performing multilingual voting with all the languages and an agreement of 50%, which indicates that the information learned by different languages will provide additional complementary evidence.\nLastly, following the methodology from BIBREF8, we extract the most confident alignments (in terms of ANE) discovered by the bilingual models. Table presents the top 10 most confident (discovered type, translation) pairs. Looking at the pairs the bilingual models are most confident about, we observe there are some types discovered by all the bilingual models (e.g. Mboshi word itua, and the concatenation oboá+ngá). However, the models still differ for most of their alignments in the table. This hints that while a portion of the lexicon might be captured independently of the language used, other structures might be more dependent of the chosen language. On this note, BIBREF11 suggests the notion of word cannot always be meaningfully defined cross-linguistically.\nThe experiment settings from this paper and evaluation protocol for the Mboshi corpus (Boundary F-scores using the ZRC speech reference) are the same from BIBREF8.

        "evidence": "Our political systems are unequal, and we suffer for it. Diversity in representation around decision-making tables is important for the health of our democratic institutions BIBREF0. One example of this inequity of representation is the gender disparity in politics: there are fewer women in politics than men, largely because women do not run for office at the same rate as men. This is because women face systemic barriers in political systems across the world BIBREF1. One of these barriers is online harassment BIBREF2, BIBREF3. Twitter is an important social media platform for politicians to share their visions and engage with their constituents. Women are disproportionately harassed on this platform because of their gender BIBREF4.\nTo raise awareness of online abuse and shift the discourse surrounding women in politics, we designed, built, and deployed ParityBOT: a Twitter bot that classifies hateful tweets directed at women in politics and then posts “positivitweets”. This paper focuses on how ParityBOT improves discourse in politics.\nPrevious work that addressed online harassment focused on collecting tweets directed at women engaged in politics and journalism and determining if they were problematic or abusive BIBREF5, BIBREF3, BIBREF6. Inspired by these projects, we go one step further and develop a tool that directly engages in the discourse on Twitter in political communities. Our hypothesis is that by seeing “positivitweets” from ParityBOT in their Twitter feeds, knowing that each tweet is an anonymous response to a hateful tweet, women in politics will feel encouraged and included in digital political communitiesBIBREF7. This will reduce the barrier to fair engagement on Twitter for women in politics. It will also help achieve gender balance in Canadian politics and improve gender equality in our society.\nTo raise awareness of online abuse and shift the discourse surrounding women in politics, we designed, built, and deployed ParityBOT: a Twitter bot that classifies hateful tweets directed at women in politics and then posts “positivitweets”.",

        "question": "Why do the authors focus on the term hate speech as abusive content in social media?",
        "answer": "Since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content.",
        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nIn the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content.",

Henry was runner-up for both the Ballon d'Or in 2003 and the FIFA World Player of the Year in 2003 and 2004. He was named the FWA Footballer of the Year a record three times, the PFA Players' Player of the Year a joint-record two times, and was named in the PFA Team of the Year six consecutive times. He was also included in the FIFA FIFPro World XI once and the UEFA Team of the Year five times.\n\nHenry made his professional debut with Monaco in 1994 before signing for defending Serie A champions Juventus. However, limited playing time, coupled with disagreements with the club's hierarchy, led to him signing for Premier League club Arsenal for £11 million in 1999. Under long-time mentor and coach Arsène Wenger, Henry became a prolific striker and Arsenal's all-time leading scorer with 228 goals in all competitions. He won the Premier League Golden Boot a record four times, won two FA Cups and two Premier League titles with the club, including one during an unbeaten Invincible season.

Joe was an inspiring leader and had a knack for managing diverse species, thus he had attracted a sizable contingent of bears and birds to work at the inn. His most valued employees were a large polar bear who served as CFO, and a brown bear from Britain who was the hotel’s concierge. Additional staff members included a large brown bear who ran the shipping and receiving department, and a hen whose feathers made her an excellent housekeeper. Security was provided by a retired Canadian police bear and a retired British police bear. And because Joe recognized the importance of staying at the forefront of innovation, the inn employed a mole to research new hotel concepts. Lastly, the inn had a small polar bear on retainer as their attorney, and an Irish doctor bear to look after the medical needs of the staff and the very occasional guest who would stay at the inn. Amazingly, Joe and his CFO had convinced the staff to work in return only for housing and an occasional chocolate coin.\n\nAlthough the inn was very small, it offered guests various activities. The most popular was a whale watching cruise. Although the ship’s captain, a penguin, was not a skilled navigator, guests were guaranteed whale sightings on every voyage because the whales worked for the inn. The inn’s spa was focused on a small gym facility, and an emotional support bear offered counseling services so that guests could heal both their bodies and minds. The most popular guest dining spot was al fresco in the inn’s award-winning garden, where a pair of geese served as bartender and wine sommelier.

As such, Easter eggs are common during the season of Eastertide (Easter season). The oldest tradition, which continues to be used in Central and Eastern Europe, is to use dyed and painted chicken eggs.\n\nAlthough eggs, in general, were a traditional symbol of fertility and rebirth, in Christianity, for the celebration of Eastertide, Easter eggs symbolize the empty tomb of Jesus, from which Jesus was resurrected. In addition, one ancient tradition was the staining of Easter eggs with the colour red \"in memory of the blood of Christ, shed as at that time of his crucifixion.\"\n\nThis custom of the Easter egg, according to many sources, can be traced to early Christians of Mesopotamia, and from there it spread into Eastern Europe and Siberia through the Orthodox Churches, and later into Europe through the Catholic and Protestant Churches. Additionally, the widespread usage of Easter eggs, according to mediaevalist scholars, is due to the prohibition of eggs during Lent after which, on Easter, they have been blessed for the occasion.\n\nA modern custom in some places is to substitute chocolate eggs wrapped in coloured foil, hand-carved wooden eggs, or plastic eggs filled with confectionery such as chocolate.",

        "question": "Do the Hidden Markov Models (HMMs) support robust inference and effective learning algorithms?",
        "answer": "Yes, they are.",
        "evidence": " Scripts were developed as a means of representing stereotypical event sequences and interactions in narratives. The benefits of scripts for encoding common sense knowledge, filling in gaps in a story, resolving ambiguous references, and answering comprehension questions have been amply demonstrated in the early work in natural language understanding BIBREF0 . The earliest attempts to learn scripts were based on explanation-based learning, which can be characterized as example-guided deduction from first principles BIBREF1 , BIBREF2 . While this approach is successful in generalizing from a small number of examples, it requires a strong domain theory, which limits its applicability.\nMore recently, some new graph-based algorithms for inducing script-like structures from text have emerged. “Narrative Chains” is a narrative model similar to Scripts BIBREF3 . Each Narrative Chain is a directed graph indicating the most frequent temporal relationship between the events in the chain. Narrative Chains are learned by a novel application of pairwise mutual information and temporal relation learning. Another graph learning approach employs Multiple Sequence Alignment in conjunction with a semantic similarity function to cluster sequences of event descriptions into a directed graph BIBREF4 . More recently still, graphical models have been proposed for representing script-like knowledge, but these lack the temporal component that is central to this paper and to the early script work. These models instead focus on learning bags of related events BIBREF5 , BIBREF6 .\nWhile the above approches demonstrate the learnability of script-like knowledge, they do not offer a probabilistic framework to reason robustly under uncertainty taking into account the temporal order of events. In this paper we present the first formal representation of scripts as Hidden Markov Models (HMMs), which support robust inference and effective learning algorithms. The states of the HMM correspond to event types in scripts, such as entering a restaurant or opening a door. Observations correspond to natural language sentences that describe the event instances that occur in the story, e.g., “John went to Starbucks. He came back after ten minutes.” The standard inference algorithms, such as the Forward-Backward algorithm, are able to answer questions about the hidden states given the observed sentences, for example, “What did John do in Starbucks?”\nThere are two complications that need to be dealt with to adapt HMMs to model narrative scripts. First, both the set of states, i.e., event types, and the set of observations are not pre-specified but are to be learned from data. We assume that the set of possible observations and the set of event types to be bounded but unknown. We employ the clustering algorithm proposed in BIBREF4 to reduce the natural language sentences, i.e., event descriptions, to a small set of observations and states based on their Wordnet similarity.\nThe second complication of narrative texts is that many events may be omitted either in the narration or by the event extraction process. More importantly, there is no indication of a time lapse or a gap in the story, so the standard forward-backward algorithm does not apply. To account for this, we allow the states to skip generating observations with some probability. This kind of HMMs, with insertions and gaps, have been considered previously in speech processing BIBREF7 and in computational biology BIBREF8 . We refine these models by allowing state-dependent missingness, without introducing additional “insert states” or “delete states” as in BIBREF8 . In this paper, we restrict our attention to the so-called “Left-to-Right HMMs” which have acyclic graphical structure with possible self-loops, as they support more efficient inference algorithms than general HMMs and suffice to model most of the natural scripts. We consider the problem of learning the structure and parameters of scripts in the form of HMMs from sequences of natural language sentences. Our solution to script learning is a novel bottom-up method for structure learning, called SEM-HMM, which is inspired by Bayesian Model Merging (BMM) BIBREF9 and Structural Expectation Maximization (SEM) BIBREF10 . It starts with a fully enumerated HMM representation of the event sequences and incrementally merges states and deletes edges to improve the posterior probability of the structure and the parameters given the data. We compare our approach to several informed baselines on many natural datasets and show its superior performance. We believe our work represents the first formalization of scripts that supports probabilistic inference, and paves the way for robust understanding of natural language texts.\nIn this paper we present the first formal representation of scripts as Hidden Markov Models (HMMs), which support robust inference and effective learning algorithms.",

Interestingly, if we calculated the Kappa only on the subset of cases that were annotated with script-specific event and participant labels by all annotators, results were better than those of the evaluation on all labeled instances (including also unrelated and related non-script events). This indicates one of the challenges of the annotation task: In many cases it is difficult to decide whether a particular event should be considered a central script event, or an event loosely related or unrelated to the script.\nFor coreference chain annotation, we calculated the percentage of pairs which were annotated by at least 3 annotators (qualified majority vote) compared to the set of those pairs annotated by at least one person (see Figure 4 ).

        "question": "What is the story of the decline of Wang Computer?",
        "evidence": "Wang Labs was one of a large number of New England-based computer companies that faltered in the late 1980s and 1990s, marking the end of the Massachusetts Miracle. For instance, the struggling Digital Equipment Corporation also downsized in the 1990s and was acquired by Compaq.\n\nA common view within the PC community is that Wang Labs failed because it specialized in computers designed specifically for word processing and did not foresee and could not compete with general-purpose personal computers with word-processing software in the 1980s. Word processing was not actually the mainstay of Wang's business by the time desktop computers began to gain in popularity. Although Wang manufactured desktops, its main business by the 1980s was its VS line of minicomputer and \"midframe\" systems. The market for these minicomputers was conquered by enhanced microcomputers like the Apple Macintosh and the Wintel PC and Sun, IBM, and Hewlett-Packard servers.\n\nAn Wang's insistence that his son, Fred Wang, succeed him contributed to the company's failure. Fred Wang was a business school graduate, \"but by almost any definition\", wrote Charles C. Kenney, \"unsuited for the job in which his father had placed him.\" His assignment, first as head of research and development, then as president of the company, led to resignations by key R&D and business personnel. Amid declining revenues, John F. Cunningham, an 18-year employee of the firm, resigned as president and COO of Wang Labs to become chairman and chief executive of Computer Consoles Inc. Cunningham resigned due to disagreement with An Wang on how to pull the company out of the slump, as well as being upset that Fred Wang was positioned, nepotistically, as An Wang's successor.\n\nOne turning point occurred when Fred Wang was head of R&D. On October 4, 1983, Wang Laboratories announced fourteen major hardware and software products and promised dates of delivery. The announcement was well received, but even at the time, there were warning signs. According to Datamation, Wang announced \"everything but the kitchen sink. And if you could attach the kitchen sink to a personal computer, they would announce that too.\" Very few of the products were close to completion, and many of them had not even been started. All were delivered late, if at all. In retrospect, this was referred to as the \"vaporware announcement,\" and it hurt the credibility of Fred Wang and Wang Laboratories.\n\nIn 1986, Fred Wang, then 36 years old, was installed as president of Wang Laboratories. However, the company's fortunes continued to decline. Unlike most computer companies that funded their growth by issuing stock, An Wang had used debt to avoid further dilution of family control of the company. By August 1989, that debt was causing conflicts with its creditors. On August 4, 1989, An Wang fired his son. Richard W. Miller, who had been with the company since 1988, replaced him as the president of Wang Laboratories.\n\nMiller announced in December 1989 that the company would start to embrace established software standards rather than use traditional proprietary designs. An Wang died in March 1990, and Miller took on the additional posts of chairman and CEO. The company underwent massive restructuring and eliminated its bank debt in August 1990, but it still ended the year with a record net loss.\n\nIn November 1990, Wang announced their first personal computers running Unix. In 1987, Wang developed a new typesetting system in conjunction with Arlington, MA-based Texet Corp. The system used Xerox printers and UNIX workstations from Sun, but the product vanished before coming to market, because few Wang employees could use or support UNIX. UNIX ran on the VS – Interactive Systems first ported IN/ix (their IBM 360 version of SYS5 UNIX) to run in a VSOS Virtual machine circa 1985, and then Wang engineers completed the port so that it ran \"native\" on the VS hardware soon thereafter – but performance was always sub-par as UNIX was never a good fit for the batch-mode nature of the VS hardware, and the line-at-a-time processing approach taken by the VS workstations; indeed, the workstation code had to be rewritten to bundle up each keystroke into a frame to be sent back to the host when running UNIX so that \"tty\" style processing could be implemented. PACE, which offered its data dictionary, excellent referential integrity, and speedy application development, was in the process of being ported to UNIX under the name OPEN Pace. A client-server RDBMS model built on the original product's ideology, OPEN Pace was demonstrated at the North American PACE User Group Conferences in both Boston and Chicago. OPEN Pace, along with a new Windows-based word processor called UpWord (which was at the time considered a strong contender to retake Wang's original market leadership from Microsoft), were touted as their new direction. However, after a marketing study[citation needed] suggested that it would require large capital investments in order to be viable competitors against Microsoft, both products were abandoned.\n\nIra Magaziner, who was brought in by Miller in 1990, proposed to take Wang out of the manufacture of computers altogether, and to go big into imaging software instead.

        "evidence": "NLP research is gradually evolving from lexical to compositional semantics BIBREF10 through the adoption of novel meaning-preserving and context-aware paradigms such as convolutional networks BIBREF11 , recurrent belief networks BIBREF12 , statistical learning theory BIBREF13 , convolutional multiple kernel learning BIBREF14 , and commonsense reasoning BIBREF15 . But while other NLP tasks have been extensively investigated, sarcasm detection is a relatively new research topic which has gained increasing interest only recently, partly thanks to the rise of social media analytics and sentiment analysis. Sentiment analysis BIBREF16 and using multimodal information as a new trend BIBREF17 , BIBREF18 , BIBREF19 , BIBREF20 , BIBREF14 is a popular branch of NLP research that aims to understand sentiment of documents automatically using combination of various machine learning approaches BIBREF21 , BIBREF22 , BIBREF20 , BIBREF23 .\nAn early work in this field was done by BIBREF6 on a dataset of 6,600 manually annotated Amazon reviews using a kNN-classifier over punctuation-based and pattern-based features, i.e., ordered sequence of high frequency words. BIBREF1 used support vector machine (SVM) and logistic regression over a feature set of unigrams, dictionary-based lexical features and pragmatic features (e.g., emoticons) and compared the performance of the classifier with that of humans. BIBREF24 described a set of textual features for recognizing irony at a linguistic level, especially in short texts created via Twitter, and constructed a new model that was assessed along two dimensions: representativeness and relevance. BIBREF5 used the presence of a positive sentiment in close proximity of a negative situation phrase as a feature for sarcasm detection. BIBREF25 used the Balanced Window algorithm for classifying Dutch tweets as sarcastic vs. non-sarcastic; n-grams (uni, bi and tri) and intensifiers were used as features for classification.\n BIBREF26 compared the performance of different classifiers on the Amazon review dataset using the imbalance between the sentiment expressed by the review and the user-given star rating. Features based on frequency (gap between rare and common words), written spoken gap (in terms of difference between usage), synonyms (based on the difference in frequency of synonyms) and ambiguity (number of words with many synonyms) were used by BIBREF3 for sarcasm detection in tweets. BIBREF9 proposed the use of implicit incongruity and explicit incongruity based features along with lexical and pragmatic features, such as emoticons and punctuation marks. Their method is very much similar to the method proposed by BIBREF5 except BIBREF9 used explicit incongruity features. Their method outperforms the approach by BIBREF5 on two datasets.\n BIBREF8 compared the performance with different language-independent features and pre-processing techniques for classifying text as sarcastic and non-sarcastic. The comparison was done over three Twitter dataset in two different languages, two of these in English with a balanced and an imbalanced distribution and the third one in Czech. The feature set included n-grams, word-shape patterns, pointedness and punctuation-based features.\nIn this work, we use features extracted from a deep CNN for sarcasm detection.

        "answer": "BRLM.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.",

We included seven of the originally defined relation types: political_affiliation, education, founder, wife/husband, job_title, nationality, and employer. The sentences were chosen in the same length range as ZuCo 1.0, and with similar Flesch reading ease scores. The dataset statistics are shown in Table TABREF2.\nOf the 739 sentences, the participants read 349 sentences in a normal reading paradigm, and 390 sentences in a task-specific reading paradigm, in which they had to determine whether a certain relation type occurred in the sentence or not. Table TABREF3 shows the distribution of the different relation types in the sentences of the task-specific annotation paradigm.\nPurposefully, there are 63 duplicates between the normal reading and the task-specific sentences (8% of all sentences). The intention of these duplicate sentences is to provide a set of sentences read twice by all participants with a different task in mind. Hence, this enables the comparison of eye-tracking and brain activity data when reading normally and when annotating specific relations (see examples in Section SECREF4).\nFurthermore, there is also an overlap in the sentences between ZuCo 1.0 and ZuCo 2.0. 100 normal reading and 85 task-specific sentences recorded for this dataset were already recorded in ZuCo 1.0. This allows for comparisons between the different recording procedures (i.e. session-specific effects) and between more participants (subject-specific effects).\nDuring the recording session, the participants read 739 sentences that were selected from the Wikipedia corpus provided by culotta2006integrating.

        "answer": "Languages are related and share many features and properties, and data sparseness.",
        "evidence": "Neural language models BIBREF0 , BIBREF1 , BIBREF2 have become an essential component in several areas of natural language processing (NLP), such as machine translation, speech recognition and image captioning. They have also become a common benchmarking application in machine learning research on recurrent neural networks (RNN), because producing an accurate probabilistic model of human language is a very challenging task which requires all levels of linguistic analysis, from pragmatics to phonology, to be taken into account.\nA typical language model is trained on text in a single language, and if one needs to model multiple languages the standard solution is to train a separate model for each language. This presupposes large quantities of monolingual data in each of the languages that needs to be covered and each model with its parameters is completely independent of any of the other models.\nWe propose instead to use a single model with real-valued vectors to indicate the language used, and to train this model with a large number of languages. We thus get a language model whose predictive distribution INLINEFORM0 is a continuous function of the language vector INLINEFORM1 , a property that is trivially extended to other neural NLP models. In this paper, we explore the “language space” containing these vectors, and in particular explore what happens when we move beyond the points representing the languages of the training corpus.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models. The second motivation is data sparseness, an issue that heavily influences the reliability of data-driven models. Resources are scarce for most languages in the world (and also for most domains in otherwise well-supported languages), which makes it hard to train reasonable parameters. By combining data from many languages, we hope to mitigate this issue.\nIn contrast to related work, we focus on massively multilingual data sets to cover for the first time a substantial amount of the linguistic diversity in the world in a project related to data-driven language modeling. We do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data. The only supervision that is giving during training is a language identifier as a one-hot encoding. From that and the actual training examples, the system learns dense vector representations for each language included in our data set along with the character-level RNN parameters of the language model itself.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models.

        "answer": "The search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem.",
        "evidence": "Medical search engines are an essential component for many online medical applications, such as online diagnosis systems and medical document databases. A typical online diagnosis system, for instance, relies on a medical search engine. The search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem. One challenge medical search engines face is the segmentation of individual clinical entities. When a user query consists of multiple clinical entities, a search engine would often fail to recognize them as separate entities. For example, the user query “fever joint pain weight loss headache” contains four separate clinical entities: “fever”, “joint pain”, “weight loss”, and “headache”. But when the search engine does not recognize them as separate entities and proceeds to retrieve results for each word in the query, it may find \"pain\" in body locations other than \"joint pain\", or it may miss \"headache\" altogether, for example. Some search engines allow the users to enter a single clinical concept by selecting from an auto-completion pick list. But this could also result in retrieving inaccurate or partial results and lead to poor user experience.\nWe want to improve the medical search engine so that it can accurately retrieve all the relevant clinical concepts mentioned in a user query, where relevant clinical concepts are defined with respect to the terminologies the search engine uses. The problem of extracting clinical concept mentions from a user query can be seen as a variant of the Concept Extraction (CE) task in the frequently-cited NLP challenges in healthcare, such as 2010 i2b2/VA BIBREF0 and 2013 ShARe/CLEF Task 1 BIBREF1. Both CE tasks in 2010 i2b2/VA and 2013 ShARe/CLEF Task 1 ask the participants to design an algorithm to tag a set of predefined entities of interest in clinical notes. These entity tagging tasks are also known as clinical Named Entity Recognition (NER). For example, the CE task in 2010 i2b2/VA defines three types of entities: “problem”, “treatment”, and “test”. The CE task in 2013 ShARe/CLEF defines various types of disorder such as “injury or poisoning”, \"disease or syndrome”, etc. In addition to tagging, the CE task in 2013 ShARe/CLEF has an encoding component which requires selecting one and only one Concept Unique Identifier (CUI) from Systematized Nomenclature Of Medicine Clinical Terms (SNOMED-CT) for each disorder entity tagged. Our problem, similar to the CE task in 2013 ShARe/CLEF, also contains two sub-problems: tagging mentions of entities of interest (entity tagging), and selecting appropriate terms from a glossary to match the mentions (term matching). However, several major differences exist. First, compared to clinical notes, the user queries are much shorter, less technical, and often less coherent. Second, instead of encoding, we are dealing with term matching where we rank a few best terms that match an entity, instead of selecting only one. This is because the users who type the queries may not have a clear idea about what they are looking for, or could be laymen who know little terminology, it may be more helpful to provide a set of likely results and let the users choose. Third, the types of entities are different. Each medical search engine may have its own types of entities to tag. There is also one minor difference in the tagging scheme between our problem and the CE task in 2013 ShARe/CLEF - We limit our scope to dealing with entities of consecutive words and not disjoint entities . We use only Beginning, Inside, Outside (BIO) tags. Given the differences listed above, we need to customize a framework consisting of an entity tagging and term matching component for our CE problem.\nThe search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem.",

The elearning developer then takes the storyboard and creates an interactive learning experience in software like Storyline 360 or Adobe Captivate. They carefully read the storyboard to understand where content belongs and how activities should be built. Elearning developers are usually more \"junior\" than instructional designers, because it takes less independent decision-making and expertise to be successful in their role.",

        "question": "In this paper, what features did the author propose to combine?",
        "answer": "The purpose of this paper is to propose to combine text features with visual features, based on a visual rendering of the document.",
        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier. When we combine the two models, we achieve state-of-the-art results over 3/4 of our datasets.\nThis paper makes the following contributions:\nAll code and data associated with this research will be released on publication.\nIn contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document.",

        "answer": "No.",
        "evidence": "As outlined in Section SECREF2, most previous work BIBREF28, BIBREF12, BIBREF13, BIBREF10, BIBREF29 make use of flat encoders that do not exploit the data structure. To keep the semantics of each element from the data-structure, we propose a hierarchical encoder which relies on two modules. The first one (module A in Figure FIGREF11) is called low-level encoder and encodes entities on the basis of their records; the second one (module B), called high-level encoder, encodes the data-structure on the basis of its underlying entities. In the low-level encoder, the traditional embedding layer is replaced by a record embedding layer as in BIBREF11, BIBREF12, BIBREF10. We present in what follows the record embedding layer and introduce our two hierarchical modules.\nThe first layer of the network consists in learning two embedding matrices to embed the record keys and values. Keys $k_{i,j}$ are embedded to $\\mathbf {k}_{i,j} \\in \\mathbb {R}^{d}$ and values $v_{i,j}$ to $\\mathbf {v}_{i,j} \\in \\mathbb {R}^{d}$, with $d$ the size of the embedding. As in previous work BIBREF11, BIBREF12, BIBREF10, each record embedding $\\mathbf {r}_{i,j}$ is computed by a linear projection on the concatenation $[\\mathbf {k}_{i,j}$; $\\mathbf {v}_{i,j}]$ followed by a non linearity:\nwhere $\\mathbf {W}_r \\in \\mathbb {R}^{2d \\times d}$ and $\\mathbf {b}_r \\in \\mathbb {R}^{d}$ are learnt parameters.\nThe low-level encoder aims at encoding a collection of records belonging to the same entity while the high-level encoder encodes the whole set of entities. Both the low-level and high-level encoders consider their input elements as unordered. We use the Transformer architecture from BIBREF21. For each encoder, we have the following peculiarities:\n\nthe Low-level encoder encodes each entity $e_i$ on the basis of its record embeddings $\\mathbf {r}_{i,j}$. Each record embedding $\\mathbf {r}_{i,j}$ is compared to other record embeddings to learn its final hidden representation $\\mathbf {h}_{i,j}$. Furthermore, we add a special record [ENT] for each entity, illustrated in Figure FIGREF11 as the last record. Since entities might have a variable number of records, this token allows to aggregate final hidden record representations $\\lbrace \\mathbf {h}_{i,j}\\rbrace _{j=1}^{J_i}$ in a fixed-sized representation vector $\\mathbf {h}_{i}$.\nthe High-level encoder encodes the data-structure on the basis of its entity representation $\\mathbf {h}_{i}$. Similarly to the Low-level encoder, the final hidden state $\\mathbf {e_i}$ of an entity is computed by comparing entity representation $\\mathbf {h}_{i}$ with each others. The data-structure representation $\\mathbf {z}$ is computed as the mean of these entity representations, and is used for the decoder initialization.\nBoth the low-level and high-level encoders consider their input elements as unordered.",

If machines could detect human emotional expressions, it could be used to improve on verity of applications such as marketing BIBREF0 , human-computer interactions BIBREF1 , political science BIBREF2 etc.\nEmotion in humans is complex and hard to distinguish. There have been many emotional models in psychology which tried to classify and point out basic human emotions such as Ekman's 6 basic emotions BIBREF3 , Plutchik's wheel of emotions BIBREF4 , or Parrott's three-level categorization of emotions BIBREF5 . These varieties show that emotions are hard to define, distinguish, and categorize even for human experts.\nBy adding the complexity of language and the fact that emotion expressions are very complex and context dependant BIBREF6 , BIBREF7 , BIBREF8 , we can see why detecting emotions in textual data is a challenging task.

However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source↔pivot and pivot↔target parallel data but no source↔target parallel data.",

The empirical success of word embeddings raises an interesting research question: Beyond words, can we learn fixed-length distributed representations for pieces of texts? The texts can be of variable-length, ranging from paragraphs to documents. Such document representations play a vital role in a large number of downstream NLP/IR/ML applications, such as text clustering, sentiment analysis, and document retrieval, which treat each piece of text as an instance. Learning a good representation that captures the semantics of each document is thus essential for the success of such applications.\nIn this paper, we introduce KeyVec, a neural network model that learns densely distributed representations for documents of variable-length. In order to capture semantics, the document representations are trained and optimized in a way to recover key information of the documents. In particular, given a document, the KeyVec model constructs a fixed-length vector to be able to predict both salient sentences and key words in the document. In this way, KeyVec conquers the problem of prior embedding models which treat every word and every sentence equally, failing to identify the key information that a document conveys. As a result, the vectorial representations generated by KeyVec can naturally capture the topics of the documents, and thus should yield good performance in downstream tasks.\nWe evaluate our KeyVec on two text understanding tasks: document retrieval and document clustering. As shown in the experimental section SECREF5 , KeyVec yields generic document representations that perform better than state-of-the-art embedding models.\nIn this paper, we introduce KeyVec, a neural network model that learns densely distributed representations for documents of variable-length.",

Since the offensive label covers both vulgar and hate speech and vulgarity and hate speech are not mutually exclusive, a tweet can be just offensive or offensive and vulgar and/or hate speech. The annotation adhered to the following guidelines:\nOffensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as:\nDirect threats or incitement, ex: احرقوا> مقرات المعارضة> (“AHrqwA mqrAt AlmEArDp” – “burn the headquarters of the opposition”) and هذا المنافق يجب قتله> (“h*A AlmnAfq yjb qtlh” – “this hypocrite needs to be killed”).\nInsults and expressions of contempt, which include: Animal analogy, ex: يا كلب> (“yA klb” – “O dog”) and كل تبن> (“kl tbn” – “eat hay”).; Insult to family members, ex: يا روح أمك> (“yA rwH Amk” – “O mother's soul”); Sexually-related insults, ex: يا ديوث> (“yA dywv” – “O person without envy”); Damnation, ex: الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”); and Attacks on morals and ethics, ex: يا كاذب> (“yA kA*b” – “O liar”)\nVulgar tweets are a subset of offensive tweets and contain profanity, such as mentions of private parts or sexual-related acts or references.\nHate speech tweets, a subset of offensive tweets containing offensive language targeting group based on common characteristics such as: Race, ex: يا زنجي> (“yA znjy” – “O negro”); Ethnicity, ex. الفرس الأنجاس> (“Alfrs AlAnjAs” – “Impure Persians”); Group or party, ex: أبوك شيوعي> (“Abwk $ywEy” – “your father is communist”); and Religion, ex: دينك القذر> (“dynk Alq*r” – “your filthy religion”).\nClean tweets do not contain vulgar or offensive language. We noticed that some tweets have some offensive words, but the whole tweet should not be considered as offensive due to the intention of users. This suggests that normal string match without considering contexts will fail in some cases. Examples of such ambiguous cases include: Humor, ex: يا عدوة الفرحة ههه> (“yA Edwp AlfrHp hhh” – “O enemy of happiness hahaha”); Advice, ex: لا تقل لصاحبك يا خنزير> (“lA tql lSAHbk yA xnzyr” – “don't say to your friend: You are a pig”); Condition, ex: إذا عارضتهم يقولون يا عميل> (“A*A EArDthm yqwlwn yA Emyl” – “if you disagree with them they will say: You are an agent”); Condemnation, ex: لماذا نسب بقول: يا بقرة؟> (“lmA*A nsb bqwl: yA bqrp?” – “Why do we insult others by saying: O cow?”); Self offense, ex: تعبت من لساني القذر> (“tEbt mn lsAny Alq*r” – “I am tired of my dirty tongue”); Non-human target, ex: يا بنت المجنونة يا كورة> (“yA bnt Almjnwnp yA kwrp” – “O daughter of the crazy one O football”); and Quotation from a movies or a story, ex: تاني يا زكي! تاني يا فاشل> (“tAny yA zky! tAny yA fA$l” – “again O Zaky! again O loser”).

Table TABREF27 shows the results.\nIn the first setting (Line 1), we train and test the monolingual model on the CoNLL data. We observe significant improvements in F1 score over the Baseline (Line 0) in both languages. Using the CoNLL 2009 dataset alone, titovcrosslingual report an F1 score of 80.9% (PU=86.8%, CO=75.7%) for German. Thus, our monolingual model outperforms their monolingual model in German. For English, they report an F1 score of 83.6% (PU=87.5%, CO=80.1%), but note that our English results are not directly comparable to theirs due to differences argument identification, as discussed in section SECREF25 . As their argument identification score is lower, perhaps their system is discarding “difficult” arguments which leads to a higher clustering score.\nIn the second setting (Line 2), we use the additional monolingual Europarl (EP) data for training. We get equivalent results in English and a significant improvement in German compared to our previous setting (Line 1). The German dataset in CoNLL is quite small and benefits from the additional EP training data. In contrast, the English model is already quite good due to a relatively big dataset from CoNLL, and good accuracy syntactic parsers. Unfortunately, titovcrosslingual do not report results with this setting.\nThe third setting (Line 3) gives the results of our multilingual model, which adds the word alignments in the EP data. Comparing with Line 2, we get non-significant improvements in both languages. titovcrosslingual obtain an F1 score of 82.7% (PU=85.0%, CO=80.6%) for German, and 83.7% (PU=86.8%, CO=80.7%) for English. Thus, for German, our multilingual Bayesian model is able to capture the cross-lingual patterns at least as well as the external penalty term in BIBREF6 . We cannot compare the English results unfortunately due to differences in argument identification.\nWe also compared monolingual and bilingual training data using a setting that emulates the standard supervised setup of separate training and test data sets. We train only on the EP dataset and test on the CoNLL dataset. Lines 4 and 5 of Table TABREF27 give the results. The multilingual model obtains small improvements in both languages, which confirms the results from the standard unsupervised setup, comparing lines 2 to 3.\nThese results indicate that little information can be learned about semantic roles from this parallel data setup. One possible explanation for this result is that the setup itself is inadequate. Given the definition of aligned arguments, only 8% of English arguments and 17% of German arguments are aligned. This plus our experiments suggest that improving the alignment model is a necessary step to making effective use of parallel data in multilingual SRI, for example by joint modeling with SRI. We leave this exploration to future work.\nThe third setting (Line 3) gives the results of our multilingual model, which adds the word alignments in the EP data.",

They share many common morphosyntactic features: both are SVO languages with free word order and rich morphology, both use the Cyrillic alphabet and share many common cognates.\nBoth Russia and the Ukraine have common academic tradition that makes it easier to collect corpora, which are comparable in terms of both genre and strictly defined academic fields. We work with such a corpus of Russian and Ukrainian academic texts, initially collected for the purposes of cross-lingual plagiarism detection. This data is available online through a number of library services, but unfortunately cannot be republished due to copyright limitations.\nThe Ukrainian subcorpus contains about 60 thousand extended summaries (Russian and Ukrainian russian`автореферат', `avtoreferat') of theses submitted between 1998 and 2011. The Russian subcorpus is smaller in the number of documents (about 16 thousand, approximately the same time period), but the documents are full texts of theses, thus the total volume of the Russian subcorpus is notably larger: 830 million tokens versus 250 million tokens in the Ukrainian one. Generally, the texts belong to one genre that can be defined as post-Soviet expository academic prose, submitted for academic degree award process.\nThe documents were converted to plain text files from MS Word format in the case of the Ukrainian subcorpus and mainly from OCRed PDF files in the case of the Russian subcorpus. Because of this, the Russian documents often suffer from OCR artifacts, such as words split with line breaks, incorrectly recognized characters and so on. However, it does not influence the resulting model much, as we show below.\nBoth Ukrainian and Russian documents come with meta data allowing to separate them into academic fields, with economics, medicine and law being most frequent topics for the Ukrainian data and economics, history and pedagogy dominating the Russian data.\nFor evaluation, 3 topics were used, distant enough from each other and abundantly presented in both subcorpora: economics, law and history. We randomly selected 100 texts in each language for each topic. As an average length of Russian texts is significantly higher (them being full theses), we cropped them, leaving only the first 5 thousand words, to mimic the size of the Ukrainian summaries. These 600 documents in 3 classes are used as a test set (see Section \"Experiment Design and Evaluation\" for the description of the conducted experiments).\nThe corpora (including test set) were PoS-tagged. Each word was replaced with its lemma followed by a PoS-tag (`russianдиссертация_S', `russianдиссертацiя_N'). Functional parts of speech (conjunctions, pronouns, prepositions, etc.) and numerals were removed from the texts.\nFor evaluation, 3 topics were used, distant enough from each other and abundantly presented in both subcorpora: economics, law and history.",

It is a dungeon crawler where the player must explore a vast world and collect a series of treasures. It was identified by BIBREF2 as a moonshot game and has been the subject of much work in leaning agents BIBREF12, BIBREF7, BIBREF11, BIBREF8. Rewards are given to the player when they collect treasures as well as when important intermediate milestones needed to further explore the world are passed. Figure FIGREF15 and Figure FIGREF1 show us a map of the world of Zork1 and the corresponding quest structure.\nThe bottleneck seen at a score of around 40 is when the player first enters the cellar on the right side of the map. The cellar is dark and you need to immediately light the lamp to see anything. Attempting to explore the cellar in the dark results in you being instantly killed by a monster known as a “grue”.\nWe make no changes from the graph update rules used by BIBREF6. Candidate interactive objects are identified by performing part-of-speech tagging on the current observation, identifying singular and proper nouns as well as adjectives, and are then filtered by checking if they can be examined using the command $examine$ $OBJ$. Only the interactive objects not found in the inventory are linked to the node corresponding to the current room and the inventory items are linked to the “you” node. The only other rule applied uses the navigational actions performed by the agent to infer the relative positions of rooms, e.g. $\\langle kitchen,down,cellar \\rangle $ when the agent performs $go$ $down$ when in the kitchen to move to the cellar.\nHyperparameters used for our agents are given below. Patience and buffer size are used for the policy chaining method as described in Section SECREF2. Cell step size is a parameter used for Go-Explore and describes how many steps are taken when exploring in a given cell state. Base hyperparameters for KG-A2C are taken from BIBREF6 and the same parameters are used for A2C.\n\nThe cellar is dark and you need to immediately light the lamp to see anything.

        "question": "Based on the paragraph below, name some authors outside of Latin America who employ magical realism in their work.",
        "evidence": "Magic realism or magical realism is a style of literary fiction and art. It paints a realistic view of the world while also adding magical elements, often blurring the lines between fantasy and reality. Magic realism often refers to literature in particular, with magical or supernatural phenomena presented in an otherwise real-world or mundane setting, commonly found in novels and dramatic performances.: 1–5  Despite including certain magic elements, it is generally considered to be a different genre from fantasy because magical realism uses a substantial amount of realistic detail and employs magical elements to make a point about reality, while fantasy stories are often separated from reality. Magical realism is often seen as an amalgamation of real and magical elements that produces a more inclusive writing form than either literary realism or fantasy.\n\nThe term magic realism is broadly descriptive rather than critically rigorous, and Matthew Strecher (1999) defines it as \"what happens when a highly detailed, realistic setting is invaded by something too strange to believe.\" The term and its wide definition can often become confused, as many writers are categorized as magical realists. The term was influenced by a German and Italian painting style of the 1920s which were given the same name. In The Art of Fiction, British novelist and critic David Lodge defines magic realism: \"when marvellous and impossible events occur in what otherwise purports to be a realistic narrative - is an effect especially associated with contemporary Latin-American fiction (for example the work of the Colombian novelist, Gabriel García Marquez) but it is also encountered in novels from other continents, such as those of Günter Grass, Salman Rushdie and Milan Kundera. All these writers have lived through great historical convulsions and wrenching personal upheavals, which they feel they cannot be adequately represented in a discourse of undisturbed realism\", citing Kundera's The Book of Laughter and Forgetting as an exemplar. \" Michiko Kakutani writes that \"The transactions between the extraordinary and the mundane that occur in so much Latin American fiction are not merely a literary technique, but also a mirror of a reality in which the fantastic is frequently part of everyday life.\" Magical realism often mixes history and fantasy, as in Salman Rushdie's Midnight's Children, in which the children born at midnight on August 15, 1947, the moment of India's independence, are telepathically linked.\n\nIrene Guenther (1995) tackles the German roots of the term, and how an earlier magic realist art is related to a later magic realist literature; meanwhile, magical realism is often associated with Latin-American literature, including founders of the genre, particularly the authors Gabriel García Márquez, Isabel Allende, Jorge Luis Borges, Juan Rulfo, Miguel Ángel Asturias, Elena Garro, Mireya Robles, Rómulo Gallegos and Arturo Uslar Pietri. In English literature, its chief exponents include Neil Gaiman, Salman Rushdie, Alice Hoffman, Nick Joaquin, and Nicola Barker. In Bengali literature, prominent writers of magic realism include Nabarun Bhattacharya, Akhteruzzaman Elias, Shahidul Zahir, Jibanananda Das and Syed Waliullah. In Japanese literature, one of the most important authors of this genre is Haruki Murakami. In Kannada literature, the writers Shivaram Karanth and Devanur Mahadeva have infused magical realism in their most prominent works. In Polish literature, magic realism is represented by Olga Tokarczuk, the 2018 Nobel Prize laureate in Literature.",

The area is a heartland of Vietnamese Buddhism, and at the time, activist Buddhist monks and civilians were at the forefront of opposition to a series of military juntas that had been ruling the nation, as well as prominently questioning the escalation of the Vietnam War.\n\nDuring the rule of the Catholic Ngô Đình Diệm, the discrimination against the majority Buddhist population generated the growth of Buddhist institutions as they sought to participate in national politics and gain better treatment. In 1965, after a series of military coups that followed the fall of the Diệm regime in 1963, Air Marshal Nguyễn Cao Kỳ and General Nguyễn Văn Thiệu finally established a stable junta, holding the positions of Prime Minister and figurehead Chief of State respectively. The Kỳ-Thiệu regime was initially almost a feudal system, being more of an alliance of warlords than a state as each corps commander ruled his area as his own fiefdom, handing some of the taxes they collected over to the government in Saigon and keeping the rest for themselves.

        "answer": "Tokyo is a massive city and even if I were to give you hundreds of recommendations, they would not begin to scratch the surface. What follows is a rundown of good things to know, food to eat, and places you may want to visit.\n\nGeneral tips and tricks:\n- Bring cash: Do a currency exchange and pick up plenty of Yen at the airport — Tokyo is a very cash-heavy town and your local currency won’t cut it. \n- Take the Narita Express: If you’re flying into Narita, the airport is far from the city center and the easiest way to get there is via Narita Express (abbreviated to N’EX), run by JR East. You have to book an actual seat on the Narita Express, and if you don't speak Japanese, don't try using one of the machines at the airport, go to an actual desk to speak to someone who can help you buy a round-trip ticket. \n- Use the Metro: Hands down, the best way to get around Tokyo. If you stay in Shinjuku, Harajuku, Shibuya or Shinagawa, you’ll be on the Yamanote Line, which will get you almost everywhere you want to go (or to an easy transfer). You’ll need to buy a reusable Suica card — again, highly highly recommend having Yen with you so you can easily load up your card. All of the Suica machines have translation options. \n- Make dinner reservations: It can be difficult to make reservations if you don't speak Japanse! If you’re staying at a hotel, use your concierge. If not, try one of following sites: Tablecheck, Tabelog and Retty.\n- Make use of these helpful phrases:\nThank you (formal): Arigatou Gozaimasu (pronounced “Ah-di-got-oh Goze-eye-moss”)\nI’m sorry / excuse me: Sumimasen (pronounced “sue-me-mah-sahn”)\nGood morning: Ohayo Gozaimasu (pronounced “oh-hi-yo Goze-eye-moss”)\nGood evening: Konbanwa (pronounced: “kon-bon-wah”)\n\nWhat to eat:\n- Omakase: If you enjoy sushi (which you probably do if you're visiting Japan!), don't miss the chance to enjoy an Omakase meal. Sushi chefs take their art seriously and whether you choose to go to a classic high-end restaurant like Sukiyabashi Jiro Roppongi (from Jiro Dreams of Sushi) or Nishiazabu Sushi Shin, or something more inventive like Udatsu, or the even more casual Sushipanchi, you will be treated to a true experience. \n- Gyoza: Who doesn't love dumplings? You should be able to find casual gyoza options throughout the city. \nYakitori: Another casual dinning experience with tons of options. If you're interested in truly experiencing yakitori and aren't afraid of squeezing through alleyways for it, visit the Golden Gai or Piss Alley.\n- Ramen: I don’t have specific recommendations for ramen because some of the best places are \"holes in the wall\" that you wander into. You can download the Ramen Beast app if you need direction. \n\nAttractions and experiences to consider:\n- Meiji Jingu: This is probably the most famous shrine in Tokyo (in Shibuya, near Harajuku) and definitely worth visiting. \n- Senso-ji: Famous Buddhist temple.\n- Imperial Palace: The residential place the Emperors and their families since 1868.\n- Sumo wrestling tournaments: Grand tournaments only happen a few times a year, but check the schedule and see if you can catch a day of matches! It’s fascinating and even more enjoyable if you read up on the rituals in advance. \n- Public baths or sentos: Experience Japanese bathing culture, but be ready to de-robe and cover any tattoos!",

        "answer": "Xie et al. formulates the MVRL with a constrained optimization problem, but the method cannot consider the constraint because the constraint is not used in optimization. As a result, the objective is the same as ours, the expected quadratic utility function. However, their method includes complicated steps, which may not be necessary, as we pointed out. Tamar et al. applies computationally difficult steps in optimization, multi-time-scale stochastic optimization, which requires control of learning parameters. This difficulty of this optimization is well-known in RL, as pointed out by Xie et al. While we point out the computational difficulties of the method of Tamar et al., which is also mentioned in the other existing studies, we avoid explicitly mentioning the problem in Xie et al., as that would be a discussion of the correctness of that paper.",
        "evidence": "In reinforcement learning (RL) for sequential decision making under uncertainty, existing methods proposed for considering mean-variance (MV) trade-off suffer from computational difficulties in computation of the gradient of the variance term. In this paper, we aim to obtain MV-efficient policies that achieve Pareto efficiency regarding MV trade-off. To achieve this purpose, we train an agent to maximize the expected quadratic utility function, in which the maximizer corresponds to the Pareto efficient policy. Our approach does not suffer from the computational difficulties because it does not include gradient estimation of the variance. In experiments, we confirm the effectiveness of our proposed methods.\nFollowing and, we consider a portfolio composed of two asset types: a liquid asset with a fixed interest rate r l , and a non-liquid asset with a time-dependent interest rate taking either r low nl or r high nl , and the transition follows a switching probability p switch . An investor can sell the liquid asset at every time step t = 1, 2, . . . , T but the non-liquid asset can only be sold after the maturity W periods. This means that when holding 1 liquid asset, we obtain r l per period; when holding 1 non-liquid asset at the t-th period, we obtain r low nl or r high nl at the t + W -th period. Besides, the non-liquid asset has a risk of not being paid with a probability p risk ; that is, if the non-liquid asset defaulted during the W periods, we could not obtain any rewards by having the asset. An investor can change the portfolio by investing a fixed fraction w of the total capital M in the non-liquid asset at each time step. A typical investment strategy is to construct a portfolio using both liquid and non-liquid assets for decreasing the variance.  In Figure, we plot performances under several hyperparameters, where the horizontal axis denotes the Var, and the vertical axis denotes the CR. Trained agents with a higher CR and lower Var are Pareto efficient. As the result shows, the EQUMRL returns more efficient portfolios than the others in almost all cases. We conjecture that this is because while the EQUMRL is an end-to-end optimization for obtaining an efficient agent, the other methods consist of several steps for solving the constrained optimization, where those multiple steps can be sources of the suboptimal result. We show CRs and Vars of some of their results in the upper, where we can confirm that the EQUMRL succeeded in minimizing the MSEs.\nIn this section, we introduce how to train a policy with the EQURL.

        "answer": "Yes, it is.",
        "evidence": "Affect is a term that subsumes emotion and longer term constructs such as mood and personality and refers to the experience of feeling or emotion BIBREF0 . BIBREF1 picard1997affective provides a detailed discussion of the importance of affect analysis in human communication and interaction. Within this context the analysis of human affect from text is an important topic in natural language understanding, examples of which include sentiment analysis from Twitter BIBREF2 , affect analysis from poetry BIBREF3 and studies of correlation between function words and social/psychological processes BIBREF4 . People exchange verbal messages which not only contain syntactic information, but also information conveying their mental and emotional states. Examples include the use of emotionally colored words (such as furious and joy) and swear words. The automated processing of affect in human verbal communication is of great importance to understanding spoken language systems, particularly for emerging applications such as dialogue systems and conversational agents.\nStatistical language modeling is an integral component of speech recognition systems, with other applications such as machine translation and information retrieval. There has been a resurgence of research effort in recurrent neural networks for language modeling BIBREF5 , which have yielded performances far superior to baseline language models based on n-gram approaches. However, there has not been much effort in building neural language models of text that leverage affective information. Current literature on deep learning for language understanding focuses mainly on representations based on word semantics BIBREF6 , encoder-decoder models for sentence representations BIBREF7 , language modeling integrated with symbolic knowledge BIBREF8 and neural caption generation BIBREF9 , but to the best of our knowledge there has been no work on augmenting neural language modeling with affective information, or on data-driven approaches to generate emotional text.\nMotivated by these advances in neural language modeling and affective analysis of text, in this paper we propose a model for representation and generation of emotional text, which we call the Affect-LM. Our model is trained on conversational speech corpora, common in language modeling for speech recognition applications BIBREF10 . Figure 1 provides an overview of our Affect-LM and its ability to generate emotionally colored conversational text in a number of affect categories with varying affect strengths. While these parameters can be manually tuned to generate conversational text, the affect category can also be automatically inferred from preceding context words. Specifically for model training, the affect category is derived from features generated using keyword spotting from a dictionary of emotional words, such as the LIWC (Linguistic Inquiry and Word Count) tool BIBREF11 . Our primary research questions in this paper are:\nQ1:Can Affect-LM be used to generate affective sentences for a target emotion with varying degrees of affect strength through a customizable model parameter?\nQ2:Are these generated sentences rated as emotionally expressive as well as grammatically correct in an extensive crowd-sourced perception experiment?\nQ3:Does the automatic inference of affect category from the context words improve language modeling performance of the proposed Affect-LM over the baseline as measured by perplexity?\nThe remainder of this paper is organized as follows. In Section \"Related Work\" , we discuss prior work in the fields of neural language modeling, and generation of affective conversational text. In Section \"LSTM Language Model\" we describe the baseline LSTM model and our proposed Affect-LM model. Section \"Experimental Setup\" details the experimental setup, and in Section \"Results\" , we discuss results for customizable emotional text generation, perception studies for each affect category, and perplexity improvements over the baseline model before concluding the paper in Section \"Conclusions and Future Work\" .\nWithin this context the analysis of human affect from text is an important topic in natural language understanding, examples of which include sentiment analysis from Twitter, affect analysis from poetry and studies of correlation between function words and social/psychological processes.",

The embedding maps each word into a lower dimensional real-value vector as its representation. Words sharing similar meanings should have similar representations. It enables our model to deal with synonyms more effectively. The question is, “can we train the network without using pre-trained word embeddings?\". We initialize word vectors randomly, and use an embedding matrix to update the word vectors in the training of the network simultaneously. Comparison results are shown in Table 3. It can be observed that pre-trained word embedding gives 2.59% higher F-measure compared to random initialization. This is partly due to the limited size of our training data. Hence using word embedding trained from other much larger corpus gives better results.\nIt is widely acknowledged that computational models using deep architecture with multiple layers have better ability to learn data representations with multiple levels of abstractions. In this section, we evaluate the power of multiple hops in this task. We set the number of hops from 1 to 9 with 1 standing for the simplest single layer network shown in Figure 4. The more hops are stacked, the more complicated the model is. Results are shown in Table 4. The single layer network has achieved a competitive performance. With the increasing number of hops, the performance improves. However, when the number of hops is larger than 3, the performance decreases due to overfitting. Since the dataset for this task is small, more parameters will lead to overfitting. As such, we choose 3 hops in our final model since it gives the best performance in our experiments.\nEssentially, memory network aims to measure the weight of each word in the clause with respect to the emotion word. The question is, will the model really focus on the words which describe the emotion cause? We choose one example to show the attention results in Table 5:\nEx.2 家人/family 的/'s 坚持/insistence 更/more 让/makes 人/people 感动/touched\nIn this example, the cause of the emotion “touched” is “insistence”. We show in Table 5 the distribution of word-level attention weights in different hops of memory network training. We can observe that in the first two hops, the highest attention weights centered on the word “more\". However, from the third hop onwards, the highest attention weight moves to the word sub-sequence centred on the word “insistence”. This shows that our model is effective in identifying the most important keyword relating to the emotion cause. Also, better results are obtained using deep memory network trained with at least 3 hops. This is consistent with what we observed in Section UID45 .\nIn order to evaluate the quality of keywords extracted by memory networks, we define a new metric on the keyword level of emotion cause extraction. The keyword is defined as the word which obtains the highest attention weight in the identified clause. If the keywords extracted by our algorithm is located within the boundary of annotation, it is treated as correct. Thus, we can obtain the precision, recall, and F-measure by comparing the proposed keywords with the correct keywords by: INLINEFORM0 \nSince the reference methods do not focus on the keywords level, we only compare the performance of Memnet and ConvMS-Memnet in Table 6. It can be observed that our proposed ConvMS-Memnet outperforms Memnet by 5.6% in F-measure. It shows that by capturing context features, ConvMS-Memnet is able to identify the word level emotion cause better compare to Memnet.\nIn our model, the training epochs are set to 20. In this section, we examine the testing error using a case study. Due to the page length limit, we only choose one example from the corpus. The text below has four clauses:\nEx.3 45天，对于失去儿子的他们是多么的漫长，宝贝回家了，这个春节是多么幸福。\nEx.3 45 days, it is long time for the parents who lost their baby. If the baby comes back home, they would become so happy in this Spring Festival.\nIn this example, the cause of emotion “happy” is described in the third clause.\nWe show in Table 7 the probability of each clause containing an emotion cause in different training epochs. It is interesting to see that our model is able to detect the correct clause with only 5 epochs. With the increasing number of training epochs, the probability associated with the correct clause increases further while the probabilities of incorrect clauses decrease generally.\nTo gain better insights into our proposed ConvMSMemnet, we conduct further experiments to understand the impact on performance by using: 1) pre-trained or randomly initialized word embedding; 2) multiple hops; 3) attention visualizations; 4) more training epochs.",

        "answer": "32053.",
        "evidence": "Online social networks have become one of the most disruptive communication platforms, as everyday billions of individuals use them to interact with each other. Their penetration in our everyday lives seems ever-growing and has in turn generated a massive volume of publicly available data open to analysis. The digital footprints left across these multiple media platforms provide us with a unique source to study and understand how the linguistic phenotype of a given user is related to social attributes such as socioeconomic status (SES).\nThe quantification and inference of SES of individuals is a long lasting question in the social sciences. It is a rather difficult problem as it may depend on a combination of individual characteristics and environmental variables BIBREF0 . Some of these features can be easier to assess like income, gender, or age whereas others, relying to some degree on self-definition and sometimes entangled with privacy issues, are harder to assign like ethnicity, occupation, education level or home location. Furthermore, individual SES correlates with other individual or network attributes, as users tend to build social links with others of similar SES, a phenomenon known as status homophily BIBREF1 , arguably driving the observed stratification of society BIBREF2 . At the same time, shared social environment, similar education level, and social influence have been shown to jointly lead socioeconomic groups to exhibit stereotypical behavioral patterns, such as shared political opinion BIBREF3 or similar linguistic patterns BIBREF4 . Although these features are entangled and causal relation between them is far from understood, they appear as correlations in the data.\nDatasets recording multiple characteristics of human behaviour are more and more available due to recent developments in data collection technologies and increasingly popular online platforms and personal digital devices. The automatic tracking of online activities, commonly associated with profile data and meta-information; the precise recording of daily activities, interaction dynamics and mobility patterns collected through mobile personal devices; together with the detailed and expert annotated census data all provide new grounds for the inference of individual features or behavioral patterns BIBREF5 . The exploitation of these data sources has already been proven to be fruitful as cutting edge recommendation systems, advanced methods for health record analysis, or successful prediction tools for social behaviour heavily rely on them BIBREF6 . Nevertheless, despite the available data, some inference tasks, like individual SES prediction, remain an open challenge.\nThe precise inference of SES would contribute to overcome several scientific challenges and could potentially have several commercial applications BIBREF7 . Further, robust SES inference would provide unique opportunities to gain deeper insights on socioeconomic inequalities BIBREF8 , social stratification BIBREF2 , and on the driving mechanisms of network evolution, such as status homophily or social segregation.\nIn this work, we take a horizontal approach to this problem and explore various ways to infer the SES of a large sample of social media users. We propose different data collection and combination strategies using open, crawlable, or expert annotated socioeconomic data for the prediction task. Specifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations. Individual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations. Each of these datasets is then used as ground-truth to infer the SES of Twitter users from profile and semantic features similar to BIBREF9 . We aim to explore and assess how the SES of social media users can be obtained and how much the inference problem depends on annotation and the user's individual and linguistic attributes.\nWe provide in Section SECREF2 an overview of the related literature to contextualize the novelty of our work. In Section SECREF3 we provide a detailed description of the data collection and combination methods. In Section SECREF4 we introduce the features extracted to solve the SES inference problem, with results summarized in Section SECREF5 . Finally, in Section SECREF6 and SECREF7 we conclude our paper with a brief discussion of the limitations and perspectives of our methods.\nSpecifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations.",

        "answer": "The earliest programming language for artificial intelligence, Lisp, was invented in 1958 by John McCarthy.",
        "evidence": "In this paper, we are exploring the historical significance of Croatian machine translation research group. The group was active in 1950s, and it was conducted by Bulcsu Laszlo, Croatian linguist, who was a pioneer in machine translation during the 1950s in Yugoslavia.\nTo put the research of the Croatian group in the right context, we have to explore the origin of the idea of machine translation. The idea of machine translation is an old one, and its origin is commonly connected with the work of Rene Descartes, i.e. to his idea of universal language, as described in his letter to Mersenne from 20.xi.1629 BIBREF0. Descartes describes universal language as a simplified version of the language which will serve as an “interlanguage” for translation. That is, if we want to translate from English to Croatian, we will firstly translate from English to an “interlanguage”, and then from the “interlanguage” to Croatian. As described later in this paper, this idea had been implemented in the machine translation process, firstly in the Indonesian-to-Russian machine translation system created by Andreev, Kulagina and Melchuk from the early 1960s.\nIn modern times, the idea of machine translation was put forth by the philosopher and logician Yehoshua Bar-Hillel (most notably in BIBREF1 and BIBREF2), whose papers were studied by the Croatian group. Perhaps the most important unrealized point of contact between machine translation and cybernetics happened in the winter of 1950/51. In that period, Bar-Hillel met Rudolf Carnap in Chicago, who introduced to him the (new) idea of cybernetics. Also, Carnap gave him the contact details of his former teaching assistant, Walter Pitts, who was at that moment with Norbert Wiener at MIT and who was supposed to introduce him to Wiener, but the meeting never took place BIBREF3. Nevertheless, Bar-Hillel was to stay at MIT where he, inspired by cybernetics, would go to organize the first machine translation conference in the world in 1952 BIBREF3.\nThe idea of machine translation was a tempting idea in the 1950s. The main military interest in machine translation as an intelligence gathering tool (translation of scientific papers, daily press, technical reports, and everything the intelligence services could get their hands on) was sparked by the Soviet advance in nuclear technology, and would later be compounded by the success of Vostok 1 (termed by the USA as a “strategic surprise”). In the nuclear age, being able to read and understand what the other side was working on was of crucial importance BIBREF4. Machine translation was quickly absorbed in the program of the Dartmouth Summer Research Project on Artificial Intelligence in 1956 (where Artificial Intelligence as a field was born), as one of the five core fields of artificial intelligence (later to be known as natural language processing). One other field was included here, the “nerve nets” as they were known back then, today commonly known as artificial neural networks. What is also essential for our discussion is that the earliest programming language for artificial intelligence, Lisp, was invented in 1958 by John McCarthy BIBREF5. But let us take a closer look at the history of machine translation. In the USA, the first major wave of government and military funding for machine translation came in 1954, and the period of abundancy lasted until 1964, when the National Research Council established the Automatic Language Processing Advisory Committee (ALPAC), which was to assess the results of the ten years of intense funding. The findings were very negative, and funding was almost gone BIBREF4, hence the ALPAC report became the catalyst for the first “AI Winter”.\nOne of the first recorded attempts of producing a machine translation system in the USSR was in 1954 BIBREF6, and the attempt was applauded by the Communist party of the Soviet Union, by the USSR Committee for Science and Technology and the USSR Academy of Sciences. The source does not specify how this first system worked, but it does delineate that the major figures of machine translation of the time were N. Andreev of the Leningrad State University, O. Kulagina and I. Melchuk of the Steklov Mathematical Institute. There is information on an Indonesian-to-Russian machine translation system by Andreev, Kulagina and Melchuk from the early 1960s, but it is reported that the system was ultimately a failure, in the same way early USA systems were. The system had statistical elements set forth by Andreev, but the bulk was logical and knowledge-heavy processing put forth by Kulagina and Melchuk. The idea was to have a logical intermediate language, under the working name “Interlingua”, which was the connector of both natural languages, and was used to model common-sense human knowledge. For more details, see BIBREF6.\nIn the USSR, there were four major approaches to machine translation in the late 1950s BIBREF7. The first one was the research at the Institute for Precise Mechanics and Computational Technology of the USSR Academy of Sciences. Their approach was mostly experimental and not much different from today's empirical methods. They evaluated the majority of algorithms known at the time algorithms over meticulously prepared datasets, whose main strength was data cleaning, and by 1959 they have built a German-Russian machine translation prototype. The second approach, as noted by Mulić BIBREF7, was championed by the team at the Steklov Mathematical Institute of the USSR Academy of Sciences led by A. A. Reformatsky. Their approach was mainly logical, and they extended the theoretical ideas of Bar-Hillel BIBREF2 to build three algorithms: French-Russian, English-Russian and Hungarian-Russian. The third and perhaps the most successful approach was the one by A. A. Lyapunov, O. S. Kulagina and R. L. Dobrushin. Their efforts resulted in the formation of the Mathematical Linguistics Seminar at the Faculty of Philology in Moscow in 1956 and in Leningrad in 1957. Their approach was mainly information-theoretic (but they also tried logic-based approaches BIBREF7), which was considered cybernetic at that time. This was the main role model for the Croatian efforts from 1957 onwards. The fourth, and perhaps most influential, was the approach at the Experimental Laboratory of the Leningrad University championed by N. D. Andreev BIBREF7. Here, the algorithms for Indonesian-Russian, Arabic-Russian, Hindu-Russian, Japanese-Russian, Burmese-Russian, Norwegian-Russian, English-Russian, Spanish-Russian and Turkish-Russian were being built. The main approach of Andreev's group was to use an intermediary language, which would capture the meanings BIBREF7. It was an approach similar to KL-ONE, which would be introduced in the West much later (in 1985) by Brachman and Schmolze BIBREF8. It is also interesting to note that the Andreev group had a profound influence on the Czechoslovakian machine translation program BIBREF9, which unfortunately suffered a similar fate as the Yugoslav one due to the lack of funding.\nAndreev's approach was in a sense \"external\". The modelling would be statistical, but its purpose would not be to mimic the stochasticity of the human thought process, but rather to produce a working machine translation system. Kulagina and Melchuk disagreed with this approach as they thought that more of what is presently called \"philosophical logic\" was needed to model the human thought process at the symbolic level, and according to them, the formalization of the human thought process was a prerequisite for developing a machine translation system (cf. BIBREF6). We could speculate that sub-symbolic processing would have been acceptable too, since that approach is also rooted in philosophical logic as a way of formalizing human cognitive functions and is also \"internal\" in the same sense symbolic approaches are.\nThere were many other centers for research in machine translation: Gorkovsky University (Omsk), 1st Moscow Institute for Foreign Languages, Computing Centre of the Armenian SSR and at the Institute for Automatics and Telemechanics of the Georgian SSR BIBREF7. It is worthwhile to note that both the USA and the USSR had access to state-of-the-art computers, and the political support for the production of such systems meant that computers were made available to researchers in machine translation. However, the results were poor in the late 1950s, and a working system was yet to be shown. All work was therefore theoretical work implemented on a computer, which proved to be sub-optimal.\nWhat is also essential for our discussion is that the earliest programming language for artificial intelligence, Lisp, was invented in 1958 by John McCarthy [17].",

No encouragements to the harasser were present in this subset of the corpus. For Dutch, the inter-annotator agreement is fair to substantial, except for curse and defamation. Analysis revealed that one of both annotators often annotated the latter as an insult, and in some cases even did not consider it as cyberbullying-related.\nIn short, the inter-rater reliability study shows that the annotation of cyberbullying is not trivial and that more fine-grained categories like defamation, curse and encouragements are sometimes hard to recognise. It appears that defamations were sometimes hard to distinguish from insults, whereas curses and exclusions were sometimes considered insults or threats. The analysis further reveals that encouragements to the harasser are subject to interpretation. Some are straightforward (e.g. `I agree we should send her hate'), whereas others are subject to the annotator's judgement and interpretation (e.g. `hahaha', `LOL').\nTo demonstrate the validity of our guidelines, inter-annotator agreement scores were calculated using Kappa on a subset of 9 each corpus.",

Modern, challenging tasks incorporating interaction, such as Atari BIBREF12 and Go BIBREF13 , push agents to learn complex strategies through trial-and-error but miss information-rich connections across vision, language, sounds, and actions.

If this disorder comes on immediately after the first appearance of the ear, the straw is also affected—but if the grain is nearly or fully formed, injury to the straw is less discernible. Wheat may mildew where the straw is perfectly fresh, but only rarely. A severe mildew, however, retards further grain and straw maturation and leads to death. Something akin to mildew is the gum, which, in all warm moist seasons, attaches itself to the ear, and often causes considerable damage. All these different disorders are generally accompanied by insects, and by minute parasitic vegetable growths, considered by many to be the cause of the damage. Their appearance, however, may justly be attributed to the diseased state of the plant; for wherever putrefaction takes place, either in animal or vegetable substances, the presence of these parasites will never be wanting.\n\nAnother disorder that affects wheat is brought on by excessive heat, which makes the plants suffer from malnutrition, and become sickly and feeble. In this atrophic state a kind of dust gathers on the stalks and leaves, which increases with the disease, till the plant is in a great measure worn out and exhausted. The only remedy in this case, and it is one that cannot easily be administered by the hand of man, is a plentiful supply of moisture, by which, if it is received before consumption is too far advanced, the crop is benefited in a degree proportional to the extent of nourishment received, and the stage at which the disease has arrived.\n\nSome people have recommended using blighted and mildewed wheat for seed. This, however may be hazardous. Light or defective wheat does vegetate and produce a plant, but the plant may be of poor quality and incapable of withstanding winter blasts.",

        "answer": "Yes, they do.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe find that the neural networks largely outperform the classical methods.",

        "evidence": "",
        "answer": "Growing tomatoes in the Pacific Northwest is very possible, but can present a number of challenges. The three biggest concerns revolve around:\n\n1. A short growing season\n2. Cooler summers\n3. Wetter than average summers\n\nHere are some solutions you can use to mitigate these challenges.\n\nDo deal with the short growing season, you need to get a headstart on growing by using starters. What this means is that instead of planting a seed in the ground in Springtime, you start a seed indoors in late winter, grow it into a small to medium plant, then transplant that \"starter\", into the ground when the temperature is warm enough. You can buy starters from Nurseries, or start your own at home. Nursery starters are easier, but by growing at home you can experiment with more rare varieties and gain experience in cultivating a plant from the seedling stage. If you grow your own it's important to slowly climatize the plant to outdoor weather leading up to the transplant date by moving it outside starting with a couple hours a day, increasing an hour or two per day over 2-3 weeks. By using starters you essentially extend the growing season by giving your plant a multi month head start. \n\nTomatoes mature best in warm to hot climates. The pacific northwest has cooler summers than many of the growing regions in the world. There is not a lot we can do to control mother nature, but there are one or two methods to help yourself here. Certain varieties of tomatoes do better in cooler summers - try and select these. If you're using starts from a local nursery they can guide you - starts from big national box stores might not be the best for your local Northwest climate. Another technique, if you are experiencing a cooler than normal Spring and start of Summer, is to build a \"hoop house\", using PVC pipe frame and a visqueen tarp. This will let light in and act as a mini-greenhouse, trapping heat around the plant. Keep in mind tomatoes need pollinators like bees to produce fruit, so once the plan t begins to flower you'll want to ensure pollination can occur.\n\nMoisture creates issues with Tomato plants as they are very susceptible to various types of fungus that grow on the leaves. Blight is one in particular common among tomatoes. The wet summers we sometimes have create conditions on the leaves conducive to fungal growth, they can also splash fungus onto the leaves from the soil. The easiest way to deal with these two issues is in proper pruning. As early as you can prune any lower sets of leaves that could possibly come into contact with the ground. Don't do this too soon as the plant needs some leaves to grow. There are many ways to prune a tomato that you can read about, but one common one in wet areas is called single stemming - in this technique you prune \"suckers\", which are the small offshoots that grow in between the main stem and the leaf stems. By pruning the suckers you prevent too much bushy growth, which will help the leaves dry out with airflow after a rain storm. The last issue related to water is that heavy late season rains will cause the fruits to swell with water and crack. There's not an easy solution here. If it's towards the end of the season and a rainstorm is coming in, this can be a good time to pick all your fruit, your green tomatoes can be used for green salsas. Some will resort to building a tarp structure above the plants to stop the rain, though this can require a bit more work and ingenuity, and you'll need another system to keep the plants watered.\n\nOverall, growing tomatoes in the Pacific Northwest is totally possible and very rewarding. Hopefully these tips help you to have a fruitful growing season!",

Getting to Bellagio is fairly easy, as it’s close to Milan.  The food is reasonably priced, although it’s generally northern Italian food (with limited options for other ethnic food).  Transportation around the lake is convenient with an efficient ferry service on Lake Como, although getting into the individual villages can be a bit challenging given the hills (so expect to walk!).  Many villages near Bellagio are also very quaint, and within walking distance – you’ll definitely get good exercise going from village to village.\n\nFor a seaside vacation, Dubrovnik is a great choice.  It’s not so convenient to get there from the United States, especially for those in the western United States since there are no direct flights.  However, it’s well worth the trip.  This walled city is jaw dropping beautiful.  The people are among the friendliest in Europe.  The food is fairly inexpensive and delicious, with a lot of seafood options.

        "question": "Why is the hierarchical encoder proposed rely on two modules?",
        "answer": "To keep the semantics of each element from the data-structure.",
        "evidence": "As outlined in Section SECREF2, most previous work BIBREF28, BIBREF12, BIBREF13, BIBREF10, BIBREF29 make use of flat encoders that do not exploit the data structure. To keep the semantics of each element from the data-structure, we propose a hierarchical encoder which relies on two modules. The first one (module A in Figure FIGREF11) is called low-level encoder and encodes entities on the basis of their records; the second one (module B), called high-level encoder, encodes the data-structure on the basis of its underlying entities. In the low-level encoder, the traditional embedding layer is replaced by a record embedding layer as in BIBREF11, BIBREF12, BIBREF10. We present in what follows the record embedding layer and introduce our two hierarchical modules.\nThe first layer of the network consists in learning two embedding matrices to embed the record keys and values. Keys $k_{i,j}$ are embedded to $\\mathbf {k}_{i,j} \\in \\mathbb {R}^{d}$ and values $v_{i,j}$ to $\\mathbf {v}_{i,j} \\in \\mathbb {R}^{d}$, with $d$ the size of the embedding. As in previous work BIBREF11, BIBREF12, BIBREF10, each record embedding $\\mathbf {r}_{i,j}$ is computed by a linear projection on the concatenation $[\\mathbf {k}_{i,j}$; $\\mathbf {v}_{i,j}]$ followed by a non linearity:\nwhere $\\mathbf {W}_r \\in \\mathbb {R}^{2d \\times d}$ and $\\mathbf {b}_r \\in \\mathbb {R}^{d}$ are learnt parameters.\nThe low-level encoder aims at encoding a collection of records belonging to the same entity while the high-level encoder encodes the whole set of entities. Both the low-level and high-level encoders consider their input elements as unordered. We use the Transformer architecture from BIBREF21. For each encoder, we have the following peculiarities:\n\nthe Low-level encoder encodes each entity $e_i$ on the basis of its record embeddings $\\mathbf {r}_{i,j}$. Each record embedding $\\mathbf {r}_{i,j}$ is compared to other record embeddings to learn its final hidden representation $\\mathbf {h}_{i,j}$. Furthermore, we add a special record [ENT] for each entity, illustrated in Figure FIGREF11 as the last record.

        "evidence": "We present our results for the binary classification tasks in Tables TABREF23 – TABREF24 in terms of average precision, average recall and macro average F1 score. The results of the regression tasks are reported in Tables TABREF25 and TABREF29 in terms of the mean absolute error between the predicted and actual scores, as well as the Spearman INLINEFORM0 correlation between the rankings induced by both sets of scores. It can be clearly seen from the results that our proposed method (EGEL-All) can effectively integrate Flickr tags with the available structured information. It outperforms the baselines for all the considered tasks. Furthermore, note that the PPMI-based weighting in EGEL-Tags consistently outperforms GloVe and that both the addition of negative examples and term selection lead to further improvements. The use of term selection leads to particularly substantial improvements for the regression problems.\nWhile our experimental results confirm the usefulness of embeddings for predicting environmental features, this is only consistently the case for the variants that use both the tags and the structured datasets. In particular, comparing BOW-Tags with EGEL-Tags, we sometimes see that the former achieves the best results. While this might seem surprising, it is in accordance with the findings in BIBREF54 , BIBREF38 , among others, where it was also found that bag-of-words representations can sometimes lead to surprisingly effective baselines. Interestingly, we note that in all cases where EGEL-KL(Tags+NS) performs worse than BOW-Tags, we also find that BOW-KL(Tags) performs worse than BOW-Tags. This suggests that for these tasks there is a very large variation in the kind of tags that can inform the prediction model, possibly including e.g. user-specific tags. Some of the information captured by such highly specific but rare tags is likely to be lost in the embedding.\nTo further analyze the difference in performance between BoW representations and embeddings, Figure TABREF29 compares the performance of the GloVe model with the bag-of-words model for predicting place scenicness, as a function of the number of tag occurrences at the considered locations. What is clearly noticeable in Figure TABREF29 is that GloVe performs better than the bag-of-words model for large corpora and worse for smaller corpora. This issue has been alleviated in our embedding method by the addition of negative examples.\nWhile our experimental results confirm the usefulness of embeddings for predicting environmental features, this is only consistently the case for the variants that use both the tags and the structured datasets.

They have agreed by the treaties to share their own sovereignty through the institutions of the European Union in some, but not all, aspects of government. State governments must agree unanimously in the Council for the union to adopt some policies; for others, collective decisions are made by qualified majority voting. These obligations and sharing of sovereignty within the EU (sometimes referred to as supranational) make it unique among international organisations, as it has established its own legal order which by the provisions of the founding treaties is both legally binding and supreme on all the member states (after a landmark ruling of the ECJ in 1964). A founding principle of the union is the principle of subsidiarity, meaning that decisions are taken collectively if and only if they cannot realistically be taken individually.\n\nAnother notable and unique feature of membership are the commissioners of the European Commission, who are appointed by each of the governments of the member states but do not represent their member state but instead work collectively in the interests of all the member states.\n\nIn the 1950s, six core states founded the EU's predecessor European Communities (Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany). The remaining states have acceded in subsequent enlargements. To accede, a state must fulfil the economic and political requirements known as the Copenhagen criteria, which require a candidate to have a democratic government and free-market economy together with the corresponding freedoms and institutions, and respect for the rule of law. Enlargement of the Union is also contingent upon the consent of all existing members and the candidate's adoption of the existing body of EU law, known as the acquis communautaire.\n\nThe United Kingdom, which had acceded to the EU's predecessor in 1973, ceased to be an EU member state on 31 January 2020.

        "evidence": "Since sarcasm in text can be expected to induce cognitive load, it is reasonable to believe that it would require more processing time BIBREF14 . Hence, fixation duration normalized over total word count should usually be higher for a sarcastic text than for a non-sarcastic one. We observe this for all participants in our dataset, with the average fixation duration per word for sarcastic texts being at least 1.5 times more than that of non-sarcastic texts. To test the statistical significance, we conduct a two-tailed t-test (assuming unequal variance) to compare the average fixation duration per word for sarcastic and non-sarcastic texts. The hypothesized mean difference is set to 0 and the error tolerance limit ( INLINEFORM0 ) is set to 0.05. The t-test analysis, presented in Table TABREF11 , shows that for all participants, a statistically significant difference exists between the average fixation duration per word for sarcasm (higher average fixation duration) and non-sarcasm (lower average fixation duration). This affirms that the presence of sarcasm affects the duration of fixation on words.\nIt is important to note that longer fixations may also be caused by other linguistic subtleties (such as difficult words, ambiguity and syntactically complex structures) causing delay in comprehension, or occulomotor control problems forcing readers to spend time adjusting eye-muscles. So, an elevated average fixation duration per word may not sufficiently indicate the presence of sarcasm. But we would also like to share that, for our dataset, when we considered readability (Flesch readability ease-score BIBREF15 ), number of words in a sentence and average character per word along with the sarcasm label as the predictors of average fixation duration following a linear mixed effect model BIBREF16 , sarcasm label turned out to be the most significant predictor with a maximum slope. This indicates that average fixation duration per word has a strong connection with the text being sarcastic, at least in our dataset.\nWe now analyze scanpaths to gain more insights into the sarcasm comprehension process.\nSince sarcasm in text can be expected to induce cognitive load, it is reasonable to believe that it would require more processing time (Ivanko and Pexman, 2003).

        "question": "Why do the authors propose to combine a query and its corresponding reply as a \"virtual sentence\"?",
        "answer": "To provide a better way of modeling utterances between two agents.",
        "evidence": "Human-computer dialog/conversation is one of the most challenging problems in artificial intelligence. Given a user-issued utterance (called a query in this paper), the computer needs to provide a reply to the query. In early years, researchers have developed various domain-oriented dialogue systems, which are typically based on rules or templates BIBREF4 , BIBREF5 , BIBREF6 . Recently, open-domain conversation systems have attracted more and more attention in both academia and industry (e.g., XiaoBing from Microsoft and DuMi from Baidu). Due to high diversity, we can hardly design rules or templates in the open domain. Researchers have proposed information retrieval methods BIBREF7 and modern generative neural networks BIBREF8 , BIBREF9 to either search for a reply from a large conversation corpus or generate a new sentence as the reply.\nIn open-domain conversations, context information (one or a few previous utterances) is particularly important to language understanding BIBREF1 , BIBREF9 , BIBREF10 , BIBREF11 . As dialogue sentences are usually casual and short, a single utterance (e.g., “Thank you.” in Figure FIGREF2 ) does not convey much meaning, but its previous utterance (“...writing an essay”) provides useful background information of the conversation. Using such context will certainly benefit the conversation system.\nHowever, tracking all previous utterances as the context is unwise. First, commercial chat-bots usually place high demands on efficiency. In a retrieval-based system, for example, performing a standard process of candidate retrieval and re-ranking for each previous utterance may well exceed the time limit (which is very short, e.g., 500ms). Second, we observe that not all sentences in the current conversation session are equally important. The sentence “Want to take a walk?” is irrelevant to the current context, and should not be considered when the computer synthesizes the reply. Therefore, it raises the question of session segmentation in conversation systems.\nDocument segmentation for general-purpose corpora has been widely studied in NLP. For example, Hearst BIBREF12 proposes the TextTiling approach; she measures the similarity of neighboring sentences based on bag-of-words features, and performs segmentation by thresholding. However, such approaches are not tailored to the dialogue genre and may not be suitable for conversation session segmentation.\nIn this paper, we address the problem of session segmentation for open-domain conversations. We leverage the classic TextTiling approach, but enhance it with modern embedding-based similarity measures. Compared with traditional bag-of-words features, embeddings map discrete words to real-valued vectors, capturing underlying meanings in a continuous vector space; hence, it is more robust for noisy conversation corpora. Further, we propose a tailored method for word embedding learning. In traditional word embedding learning, the interaction between two words in a query and a reply is weaker than that within an utterance. We propose to combine a query and its corresponding reply as a “virtual sentence,” so that it provides a better way of modeling utterances between two agents.\nWe propose to combine a query and its corresponding reply as a “virtual sentence,” so that it provides a better way of modeling utterances between two agents.",

We evaluate monolingual SRI with a large unlabeled dataset, bilingual SRI with a parallel corpus, bilingual SRI with annotations available for the source language, and monolingual SRI with a small labeled dataset. Increasing the amount of monolingual unlabeled data significantly improves SRI in German but not in English. Adding word alignments in parallel sentences results in small, non significant improvements, even if there is some labeled data available in the source language. This difficulty in showing the usefulness of parallel corpora for SRI may be due to the current assumptions about role alignments, which mean that only a small percentage of roles are aligned. Further analyses reveals that annotating small amounts of data can easily outperform the performance gains obtained by adding large unlabeled dataset as well as adding parallel corpora.\nFuture work includes training on different language pairs, on more than two languages, and with more inclusive models of role alignment.\nFurther analyses reveals that annotating small amounts of data can easily outperform the performance gains obtained by adding large unlabeled dataset as well as adding parallel corpora.

        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word.",

Milk consumption was unknown, and – for cultural and religious reasons – meat was not eaten. Cattle were highly prized and valuable, too expensive for a poor farmer to buy.: 2 \n\nJapan was effectively isolated from the rest of the world from 1635 until 1854; there was no possibility of the intromission of foreign genes to the cattle population during this time.

        "question": "What do the authors focus on in this paper?",
        "answer": "The authors focus on learning binary codes for text documents.",
        "evidence": "One of the significant challenges in contemporary information processing is the sheer volume of available data. BIBREF0 , for example, claim that the amount of digital data in the world doubles every two years. This trend underpins efforts to develop algorithms that can efficiently search for relevant information in huge datasets. One class of such algorithms, represented by, e.g., Locality Sensitive Hashing BIBREF1 , relies on hashing data into short, locality-preserving binary codes BIBREF2 . The codes can then be used to group the data into buckets, thereby enabling sublinear search for relevant information, or for fast comparison of data items. Most of the algorithms from this family are data-oblivious, i.e. can generate hashes for any type of data. Nevertheless, some methods target specific kind of input data, like text or image.\nIn this work we focus on learning binary codes for text documents. An important work in this direction has been presented by BIBREF3 . Their semantic hashing leverages autoencoders with sigmoid bottleneck layer to learn binary codes from a word-count bag-of-words (BOW) representation. Salakhutdinov & Hinton report that binary codes allow for up to 20-fold improvement in document ranking speed, compared to real-valued representation of the same dimensionality. Moreover, they demonstrate that semantic hashing codes used as an initial document filter can improve precision of TF-IDF-based retrieval. Learning binary representation from BOW, however, has its disadvantages. First, word-count representation, and in turn the learned codes, are not in itself stronger than TF-IDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such high-dimensional vectors is impractical. Salakhutdinov & Hinton restricted the BOW vocabulary in their experiments to 2000 most frequent words.\nBinary codes have also been applied to cross-modal retrieval where text is one of the modalities. Specifically, BIBREF4 incorporated tag information that often accompany text documents, while BIBREF5 employed siamese neural networks to learn single binary representation for text and image data.\nRecently several works explored simple neural models for unsupervised learning of distributed representations of words, sentences and documents. BIBREF6 proposed log-linear models that learn distributed representations of words by predicting a central word from its context (CBOW model) or by predicting context words given the central word (Skip-gram model). The CBOW model was then extended by BIBREF7 to learn distributed representations of documents. Specifically, they proposed Paragraph Vector Distributed Memory (PV-DM) model, in which the central word is predicted given the context words and the document vector. During training, PV-DM learns the word embeddings and the parameters of the softmax that models the conditional probability distribution for the central words. During inference, word embeddings and softmax weights are fixed, but the gradients are backpropagated to the inferred document vector. In addition to PV-DM, Le & Mikolov studied also a simpler model, namely Paragraph Vector Distributed Bag of Words (PV-DBOW). This model predicts words in the document given only the document vector. It therefore disregards context surrounding the predicted word and does not learn word embeddings. Le & Mikolov demonstrated that paragraph vectors outperform BOW and bag-of-bigrams in information retrieval task, while using only few hundreds of dimensions. These models are also amendable to learning and inference over large vocabularies. Original CBOW network used hierarchical softmax to model the probability distribution for the central word. One can also use noise-contrastive estimation BIBREF8 or importance sampling BIBREF9 to approximate the gradients with respect to the softmax logits.\nAn alternative approach to learning representation of pieces of text has been recently described by BIBREF10 . Networks proposed therein, inspired by the Skip-gram model, learn to predict surrounding sentences given the center sentence. To this end, the center sentence is encoded by an encoder network and the surrounding sentences are predicted by a decoder network conditioned on the center sentence code. Once trained, these models can encode sentences without resorting to backpropagation inference. However, they learn representations at the sentence level but not at the document level.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PV-DM that learn short binary codes for text documents. One inspiration for binary paragraph vectors comes from a recent work by BIBREF11 on learning binary codes for images. Specifically, we introduce a sigmoid layer to the paragraph vector models, and train it in a way that encourages binary activations. We demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes. We also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora. Finally, we study models that simultaneously learn short binary codes for document filtering and longer, real-valued representations for ranking. While BIBREF11 employed a supervised criterion to learn image codes, binary paragraph vectors remain unsupervised models: they learn to predict words in documents.\nIn this work we focus on learning binary codes for text documents.",

        "question": "What kind of method is designed?",
        "answer": "A novel pre-training method called BRidge Language Modeling (BRLM).",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nBesides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$leftrightarrow $target bilingual data to obtain a universal encoder for different languages.",

        "answer": "Yes.",
        "evidence": "Sarcasm is an intensive, indirect and complex construct that is often intended to express contempt or ridicule . Sarcasm, in speech, is multi-modal, involving tone, body-language and gestures along with linguistic artifacts used in speech. Sarcasm in text, on the other hand, is more restrictive when it comes to such non-linguistic modalities. This makes recognizing textual sarcasm more challenging for both humans and machines.\nSarcasm detection plays an indispensable role in applications like online review summarizers, dialog systems, recommendation systems and sentiment analyzers. This makes automatic detection of sarcasm an important problem. However, it has been quite difficult to solve such a problem with traditional NLP tools and techniques. This is apparent from the results reported by the survey from DBLP:journals/corr/JoshiBC16. The following discussion brings more insights into this.\nConsider a scenario where an online reviewer gives a negative opinion about a movie through sarcasm: “This is the kind of movie you see because the theater has air conditioning”. It is difficult for an automatic sentiment analyzer to assign a rating to the movie and, in the absence of any other information, such a system may not be able to comprehend that prioritizing the air-conditioning facilities of the theater over the movie experience indicates a negative sentiment towards the movie. This gives an intuition to why, for sarcasm detection, it is necessary to go beyond textual analysis.\nWe aim to address this problem by exploiting the psycholinguistic side of sarcasm detection, using cognitive features extracted with the help of eye-tracking. A motivation to consider cognitive features comes from analyzing human eye-movement trajectories that supports the conjecture: Reading sarcastic texts induces distinctive eye movement patterns, compared to literal texts. The cognitive features, derived from human eye movement patterns observed during reading, include two primary feature types:\nThe cognitive features, along with textual features used in best available sarcasm detectors, are used to train binary classifiers against given sarcasm labels. Our experiments show significant improvement in classification accuracy over the state of the art, by performing such augmentation.\nHowever, it has been quite difficult to solve such a problem with traditional NLP tools and techniques.

        "question": "What is the OWL?",
        "answer": "The de-facto standard for machine processable and interoperable ontologies on the SW.",
        "evidence": "OWL BIBREF15 is the de-facto standard for machine processable and interoperable ontologies on the SW. In its second version, OWL is equivalent to the description logic $\\mathcal {SROIQ}(D)$. Such expressiveness has a higher computational cost but allows the development of interesting applications such as automated reasoning BIBREF16. OWL 2 ontologies consist of the following three different syntactic categories:\nEntities, such as classes, properties, and individuals, are identified by IRIs. They form the primitive terms and constitute the basic elements of an ontology. Classes denote sets of individuals and properties link two individuals or an individual and a data value along a property. For example, a class :Animal can be used to represent the set of all animals. Similarly, the object property :childOf can be used to represent the parent-child relationship and the data property :birthDate assigns a particular birth date to an individual. Finally, the individual :Alice can be used to represent a particular person called \"Alice\".\nExpressions represent complex notions in the domain being described. For example, a class expression describes a set of individuals in terms of the restrictions on the individuals' characteristics. OWL offers existential (SOME) or universal (ONLY) qualifiers and a variety of typical logical constructs, such as negation (NOT), other Boolean operators (OR, AND), and more constructs such as cardinality restriction (MIN, MAX, EXACTLY) and value restriction (VALUE), to create class expressions. Such constructs can be combined in arbitrarily complex class expressions CE according to the following grammar\nwhere A is an atomic class, C and D are class expressions, R is an object property, a as well as a$_1$ to a$_m$ with $\\texttt {m} \\ge 1$ are individuals, and $\\texttt {n} \\ge 0$ is an integer.\nAxioms are statements that are asserted to be true in the domain being described. Usually, one distinguish between (1) terminological and (2) assertional axioms. (1) terminological axioms are used to describe the structure of the domain, i.e., the relationships between classes resp. class expressions. For example, using a subclass axiom (SubClassOf:), one can state that the class :Koala is a subclass of the class :Animal. Classes can be subclasses of other classes, thus creating a taxonomy. In addition, axioms can arrange properties in hierarchies (SubPropertyOf:) and can assign various characteristics (Characteristics:) such as transitivity or reflexivity to them. (2) Assertional axioms formulate facts about individuals, especially the classes they belong to and their mutual relationships. OWL can be expressed in various syntaxes with the most common computer readable syntax being RDF/XMLA more human-readable format is the MOS BIBREF17. For example, the class expression that models people who work at a university that is located in Spain could be as follows in MOS:\nLikewise, expressing that every professor works at a university would read as\nOWL 2 ontologies consist of Entities, Expressions and Axioms as introduced in subsec:owl. While both expressions and axioms can be mapped to RDF, i.e. into a set of RDF triples, using this mapping and applying the triple-based verbalization on it would lead to a non-human understandable text in many cases. For example, the intersection of two classes :A and :B can be represented in RDF by the six triples\nThe verbalization of these triples would result in Something that is a class and the intersection of something whose first is A and whose rest is something whose first is B and whose rest ist nil., which is obviously far away from how a human would express it in NL. Therefore, generating NL from OWL requires a different procedure based on its syntactic categories, OWL expressions and OWL axioms. We show the general rules for each of them in the following.\nIn theory, class expressions can be arbitrarily complex, but as it turned out in some previous analysis BIBREF22, in practice they seldom arise and can be seen as some corner cases. For example, an ontology could contain the following class expression about people and their birth place:\nClass expressions do have a tree-like structure and can simply be parsed into a tree by means of the binary OWL class expressions constructors contained in it. For our example, this would result in the following tree:\nevery tree node/.style=align=center,anchor=base,font=, edge from parent/.style= thick, draw, edge from parent path=(.south) – +(0,-8pt) -| () frontier/.style=distance from root=9 [.AND Person [.SOME birthPlace [.AND City [.VALUE locatedIn France ] ] ] ]\nSuch a tree can be traversed in post-order, i.e. sub-trees are processed before their parent nodes recursively. For the sake of simplicity, we only process sub-trees that represent proper class expression in our example, i.e. we omit birthPlace, locatedIn, and France. Moreover and again for simplicity, we'll explain the transformation process by starting from the right-hand side of the tree. Thus, in our example we begin with the class expression City which is transformed to everything that is a city and locatedIn VALUE France resulting in everything that is located in France by application of a rule. Both class expressions are used in the conjunction City AND locatedIn VALUE France. Thus, the next step would be to merge both phrases. An easy way is to use the coordinating conjunction and, i.e. everything that is a city and everything that is located in France. Although the output of this transformation is correct, it still contains unnecessarily redundant information. Therefore, we apply the aggregation procedure described in subsec:grouping, i.e. we get everything that is a city and located in France. Yet, the aggregation can still be improved: if there is any atomic class in the conjunction, we know that this is more specific than the placeholder everything. Thus, we can replace it by the plural form of the class, finally resulting in cities that are located in France. The same procedure is applied for its parent class expression being the existential restriction\nThis will be transformed to everything whose birth place is a city that is located in France. Note, that we used the singular form here, assuming that the property birthPlace is supposed to be functional in the ontology. In the last step, we process the class expression Person, which gives us everything that is a person. Again, due to the conjunction we merge this result with with the previous one, such that in the end we get people whose birth place is a city that is located in France.\nAs we described in sec:owl, OWL axioms can roughly be categorized into terminological and assertional axioms. Therefore, we have different procedures for processing each category:\nAssertional Axioms (ABox Axioms) - Most assertional axioms assert individuals to atomic classes or relate individuals to another individual resp. literal value. For example, axioms about the type as well as birth place and birth date of Albert Einstein can be expressed by\nThose axioms can simply be rewritten as triples, thus, we can use the same procedure as we do for triples (sec:singletriple). Converting them into NL gives us Albert Einstein is a person whose birth place is Ulm and whose birth date is 14 March 1879. OWL also allows for assigning an individual to a complex class expression. In that case we'll use our conversion of OWL class expressions as described in subsec:owlce.\nTerminological Axioms (TBox Axioms) - According to power2010, most of the terminological axioms used in ontologies are subclass axioms. By definition, subclass and superclass can be arbitrarily complex class expressions $\\texttt {CE}_1$ and $\\texttt {CE}_2$, i.e. [language=manchester,mathescape=true]CE$_1$ SubClassOf CE$_2$, but in praxis it is quite often only used with atomic classes as subclass or even more simple with the superclass also beeing an atomic class. Nevertheless, we support any kind of subclass axiom and all other logical OWL axioms in LD2NL. For simplicity, we outline here how we verbalize subclass axioms in LD2NL. The semantics of a subclass axiom denotes that every individual of the subclass also belongs to the superclass. Thus, the verbalization seems to be relatively straightforward, i.e. we verbalize both class expressions and follow the template : every $\\rho (\\texttt {\\texttt {CE}$1$})$ is a $\\rho (\\texttt {\\texttt {CE}$2$})$. Obviously, this works pretty well for subclass axioms with atomic classes only. For example, the axiom\nis verbalized as every scientist is a person.\nThis work was supported by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) through the projects LIMBO (no. 19F2029I) and OPAL (no. 19F2028A).

In fact, online harassment becomes very common in Twitter and there have been a lot of critics that Twitter has become the platform for many racists, misogynists and hate groups which can express themselves openly. Online harassment is usually in the form of verbal or graphical formats and is considered harassment, because it is neither invited nor has the consent of the receipt. Monitoring the contents including sexism and sexual harassment in traditional media is easier than monitoring on the online social media platforms like Twitter. The main reason is because of the large amount of user generated content in these media. So, the research about the automated detection of content containing sexual harassment is an important issue and could be the basis for removing that content or flagging it for human evaluation.

Here $[\\mathbf {a};\\mathbf {b}]$ denotes the concatenation of vectors $\\mathbf {a}$ and $\\mathbf {b}$.\nWe use bidirectional LSTMs to encode the sentence $(\\mathbf {x}_1^s, \\mathbf {x}_2^s, ..., \\mathbf {x}_n^s)$ to get a contextualized representation for each token:\nwhere $\\overrightarrow{\\mathbf {h}}^{s}_i$ and $\\overleftarrow{\\mathbf {h}}^{s}_i$ are the hidden states at the $i$-th time step of the forward and the backward LSTMs. The output state of the sentence encoder is the concatenation of forward and backward hidden states: $\\mathbf {h}^{s}_i=[\\overrightarrow{\\mathbf {h}}^{s}_i;\\overleftarrow{\\mathbf {h}}^{s}_i]$. The contextualized representation of the sentence is $(\\mathbf {h}^{s}_1, \\mathbf {h}^{s}_2, ..., \\mathbf {h}^{s}_n)$.\nFor the relation encoder, we firstly join all items in the n-ary relation $M$ into a sequence. Then we only take answer position embedding as an extra feature for the sequence: $\\mathbf {x}_i^m= [\\mathbf {w}_i; \\mathbf {a}_i]$. Similarly, we take another bidirectional LSTMs to encode the relation sequence and derive the corresponding contextualized representation $(\\mathbf {h}^{m}_1, \\mathbf {h}^{m}_2, ..., \\mathbf {h}^{m}_n)$.\nWe use an LSTM as the decoder to generate the question. The decoder predicts the word probability distribution at each decoding timestep to generate the question. At the t-th timestep, it reads the word embedding $\\mathbf {w}_{t}$ and the hidden state $\\mathbf {u}_{t-1}$ of the previous timestep to generate the current hidden state:\nWe design a gated attention mechanism to jointly attend the sentence representation and the relation representation. For sentence representation $(\\mathbf {h}^{s}_1, \\mathbf {h}^{s}_2, ..., \\mathbf {h}^{s}_n)$, we employ the Luong2015EffectiveAT's attention mechanism to obtain the sentence context vector $\\mathbf {c}^s_t$,\nwhere $\\mathbf {W}_a$ is a trainable weight. Similarly, we obtain the vector $\\mathbf {c}^m_t$ from the relation representation $(\\mathbf {h}^{m}_1, \\mathbf {h}^{m}_2, ..., \\mathbf {h}^{m}_n)$. To jointly model the sentence and the relation, a gating mechanism is designed to control the information flow from two sources:\nwhere $\\odot $ represents element-wise dot production and $\\mathbf {W}_g, \\mathbf {W}_h$ are trainable weights. Finally, the predicted probability distribution over the vocabulary $V$ is computed as:\nwhere $\\mathbf {W}_V$ and $\\mathbf {b}_V$ are parameters.\nTo deal with the rare and unknown words, the decoder applies the pointing method BIBREF10, BIBREF11, BIBREF12 to allow copying a token from the input sentence at the $t$-th decoding step. We reuse the attention score $\\mathbf {\\alpha }_{t}^s$ and $\\mathbf {\\alpha }_{t}^m$ to derive the copy probability over two source inputs:\nDifferent from the standard pointing method, we design a dual copy mechanism to copy from two sources with two gates. The first gate is designed for determining copy tokens from two sources of inputs or generate next word from $P_V$, which is computed as $g^v_t = \\text{sigmoid}(\\mathbf {w}^v_g \\tilde{\\mathbf {h}}_t + b^v_g)$. The second gate takes charge of selecting the source (sentence or relation) to copy from, which is computed as $g^c_t = \\text{sigmoid}(\\mathbf {w}^c_g [\\mathbf {c}_t^s;\\mathbf {c}_t^m] + b^c_g)$. Finally, we combine all probabilities $P_V$, $P_S$ and $P_M$ through two soft gates $g^v_t$ and $g^c_t$. The probability of predicting $w$ as the $t$-th token of the question is:\nGiven the answer $A$, sentence $S$ and relation $M$, the training objective is to minimize the negative log-likelihood with regard to all parameters:\nwhere $\\mathcal {\\lbrace }Q\\rbrace $ is the set of all training instances, $\\theta $ denotes model parameters and $\\text{log} P(Q|A,S,M;\\theta )$ is the conditional log-likelihood of $Q$.\nIn testing, our model targets to generate a question $Q$ by maximizing:\nAs shown in Figure 3, our framework consists of four components (1) Sentence Encoder and Relation Encoder, (2) Decoder, (3) Gated Attention Mechanism and (4) Dual Copy Mechanism.",

        "answer": "For Vanessa, we’ll choose for her to perform a one-rep max assessment, specifically with the bench press. This is because she has experience with lifting weights. To start, she should warm up by completing several submaximal repetitions. We’re going to select an initial weight of 50-70% of her capacity, and progressively increase resistance by 2.5 to 20 kg until the subject cannot complete the repetitions. The final weight lifted should be the absolute 1-RM. Some common error we want to watch for is to make sure that the repetitions are performed at the same speed of movement and range of motion to ensure consistency. Additionally, on the setup portion, we should check the surroundings for hazards, set the bar to the right height for Vanessa based on her arm length, remove safety bars from both sides of the rack, secure weights correctly with safety clips, and have a spotter present. We should also make sure there is a proper progression of weight lifted, she’s not bouncing the bar off her chest, that she’s maintaining a neutral spine, and that she is breathing during the lift. For Lauren, because she has never participated in resistance training, we will select the flexed arm support test, as she may not be able to perform the dynamic push-up assessment properly. To start, she should have her hands outside her shoulders, and keep her back and legs straight. She should lower her body until the upper arm is parallel to the floor or the elbow is flexed at 90 degrees. She should be supporting her body in a push-up position from the knees. Some common mistakes include not breathing during the assessment, having a too-wide or too-narrow width for her hands, not maintaining a straight back and legs, and not lowering her body enough for the assessment.",

Amazon, Yelp, IMDB are sentence-level sentiment classification datasets which have been used in recent work BIBREF15 while MR BIBREF16 contains movie reviews based on sentiment polarity. MPQA BIBREF17 is a dataset for opinion polarity detection, Subj BIBREF18 for classifying a sentence as subjective or objective and TREC BIBREF19 is a dataset for question type classification.\nWe use 3 popular text classification models: word-LSTM BIBREF20, word-CNN BIBREF21 and a fine-tuned BERT BIBREF12 base-uncased classifier. For each dataset we train the model on the training data and perform the adversarial attack on the test data. For complete model details refer to Appendix.\nAs a baseline, we consider TextFooler BIBREF11 which performs synonym replacement using a fixed word embedding space BIBREF22. We only consider the top $K{=}50$ synonyms from the MLM predictions and set a threshold of 0.8 for the cosine similarity between USE based embeddings of the adversarial and input text.\nResults We perform the 4 modes of our attack and summarize the results in Table . Across datasets and models, our BAE attacks are almost always more effective than the baseline attack, achieving significant drops of 40-80% in test accuracies, with higher average semantic similarities as shown in parentheses. BAE-R+I is the strongest attack since it allows both replacement and insertion at the same token position, with just one exception. We observe a general trend that the BAE-R and BAE-I attacks often perform comparably, while the BAE-R/I and BAE-R+I attacks are much stronger. We observe that the BERT-based classifier is more robust to the BAE and TextFooler attacks than the word-LSTM and word-CNN models which can be attributed to its large size and pre-training on a large corpus.\nThe baseline attack is often stronger than the BAE-R and BAE-I attacks for the BERT based classifier. We attribute this to the shared parameter space between the BERT-MLM and the BERT classifier before fine-tuning. The predicted tokens from BERT-MLM may not drastically change the internal representations learned by the BERT classifier, hindering their ability to adversarially affect the classifier prediction.\nEffectiveness We study the effectiveness of BAE on limiting the number of R/I operations permitted on the original text. We plot the attack performance as a function of maximum $\\%$ perturbation (ratio of number of word replacements and insertions to the length of the original text) for the TREC dataset. From Figure , we clearly observe that the BAE attacks are consistently stronger than TextFooler. The classifier models are relatively robust to perturbations up to 20$\\%$, while the effectiveness saturates at 40-50$\\%$. Surprisingly, a 50$\\%$ perturbation for the TREC dataset translates to replacing or inserting just 3-4 words, due to the short text lengths.\nQualitative Examples We present adversarial examples generated by the attacks on a sentence from the IMDB and Yelp datasets in Table . BAE produces more natural looking examples than TextFooler as tokens predicted by the BERT-MLM fit well in the sentence context. TextFooler tends to replace words with complex synonyms, which can be easily detected. Moreover, BAE's additional degree of freedom to insert tokens allows for a successful attack with fewer perturbations.\nHuman Evaluation We consider successful adversarial examples generated from the Amazon and IMDB datasets and verify their sentiment and grammatical correctness. Human evaluators annotated the sentiment and the grammar (Likert scale of 1-5) of randomly shuffled adversarial examples and original texts. From Table , BAE and TextFooler have inferior accuracies compared to the Original, showing they are not always perfect. However, BAE has much better grammar scores, suggesting more natural looking adversarial examples.\nAblation Study We analyze the benefits of R/I operations in BAE in Table . From the table, the splits $\\mathbb {A}$ and $\\mathbb {B}$ are the $\\%$ of test points which compulsorily need I and R operations respectively for a successful attack. We can observe that the split $\\mathbb {A}$ is larger than $\\mathbb {B}$ thereby indicating the importance of the I operation over R. Test points in split require both R and I operations for a successful attack. Interestingly, split is largest for Subj, which is the most robust to attack (Table ) and hence needs both R/I operations. Thus, this study gives positive insights towards the importance of having the flexibility to both replace and insert words.\nRefer to the Appendix for additional results, effectiveness graphs and details of human evaluation.\nWe calculate the sentiment accuracy by asking 3 annotators to predict the sentiment for each sentence in this shuffled set.",

Hence for this baseline, we train with the relatively sparse labels (the voxels), whose resolution is lower than the pre-computed dense occupancy labels.",

For occupancy,\n(1) where P 0+ I and P 0− I denotes inward and outward near-surface query points, and λ or represents the loss weight of the occupancy geometric regularization. The facing direction of the mesh surface (determining inward or outward) can be determined by normals (if available), or via rendering the surface in all views as in the RGBD captures  (with the surface facing toward camera as the \"outward\" side). The three terms in Eq. 1 correspond to the three types of losses in Fig.(c) (\"∇\", \"+\", \"−\") respectively. For SDF, we set the loss similar to:\nwhere P 0 I denotes the query points on the ground truth surface only, and λ sr and λ sn represents the loss weight for the signed distance geometric regularization term and normal term respectively. The three terms represents the Eikonal regularization, surface zero-SDF loss, and the surface normal loss respectively, with the last term optional. Note now the loss functions in Eq. 1, 2 no longer require the implicit ground truth label for query points far away from the ground truth surface, enabling training with the real-world imperfect scanned data.\nIn both cases, the availability of surface normals is optional.\nPractically, we found only our proposed loss for the occupancy version (Fig.(c), Eq. 1) demonstrates capability to be applicable for the real-world single-view feed-forward scenario, and use Eq. 1 rather than Eq. 2 in all of our experiments. First, learning with the Eikonal term (Eq. 2) suffers severely from its sensitivity of model initialization. We found either the SDF or the Truncated SDF (TSDF) representation model cannot easily converge during training. Specifically, we found it poses numerical difficulties when the model is learned to predict a large distance value or a constant truncation value for the majority of the query points in the air that is far from any surfaces. This becomes a major problem when we extend from the single objects scenario or single scene fitting. Second, our loss function (Eq. 1) can significantly save memory footprint during training and enable large batch size training, which is crucial in our learning framework. Unlike in Eq. 2 where all the query points require spatial gradient computation, which leads to 3× higher of memory footprint, in our loss function (Eq. 1), only the non-surface query points do. We set the query point batch size of the non-surface points (512 in practice) to be much smaller than the critical near-surface points (4096 in practice), enabling learning with the image batch size of 32 in our real-scene training.\nAs obtaining the full labels ˜f(ϕ; x, y, z) for query points (x, y, z) from all the locations PI is nontrivial for complex geometry from real-world (Fig. 2) and due to additional engineering constraints\non runtime loading and memory bottleneck for the sufficiently dense pre-computed query point\noccupancy labels, we propose to incorporate the loss w.r.t. the spatial gradients.",

With the availability of GPS systems in current electronic devices such as smartphones, latitude and longitude coordinates are nowadays commonly made available as well. The tags associated with such georeferenced photos often describe the location where these photos were taken, and Flickr can thus be regarded as a source of environmental information. The use of Flickr for modelling urban environments has already received considerable attention. For instance, various approaches have been proposed for modelling urban regions BIBREF0 , and for identifying points-of-interest BIBREF1 and itineraries BIBREF2 , BIBREF3 . However, the usefulness of Flickr for characterizing the natural environment, which is the focus of this paper, is less well-understood.\nMany recent studies have highlighted that Flickr tags capture valuable ecological information, which can be used as a complementary source to more traditional sources. To date, however, ecologists have mostly used social media to conduct manual evaluations of image content with little automated exploitation of the associated tags BIBREF4 , BIBREF5 , BIBREF6 . One recent exception is BIBREF7 , where bag-of-words representations derived from Flickr tags were found to give promising result for predicting a range of different environemental phenomena.\nOur main hypothesis in this paper is that by using vector space embeddings instead of bag-of-words representations, the ecological information which is implicitly captured by Flickr tags can be utilized in a more effective way. Vector space embeddings are representations in which the objects from a given domain are encoded using relatively low-dimensional vectors. They have proven useful in natural language processing, especially for encoding word meaning BIBREF8 , BIBREF9 , and in machine learning more generally. In this paper, we are interested in the use of such representations for modelling geographic locations. Our main motivation for using vector space embeddings is that they allow us to integrate the textual information we get from Flickr with available structured information in a very natural way. To this end, we rely on an adaptation of the GloVe word embedding model BIBREF9 , but rather than learning word vectors, we learn vectors representing locations. Similar to how the representation of a word in GloVe is determined by the context words surrounding it, the representation of a location in our model is determined by the tags of the photos that have been taken near that location. To incorporate numerical features from structured environmental datasets (e.g. average temperature), we associate with each such feature a linear mapping that can be used to predict that feature from a given location vector. This is inspired by the fact that salient properties of a given domain can often be modelled as directions in vector space embeddings BIBREF10 , BIBREF11 , BIBREF12 . Finally, evidence from categorical datasets (e.g. land cover types) is taken into account by requiring that locations belonging to the same category are represented using similar vectors, similar to how semantic types are sometimes modelled in the context of knowledge graph embedding BIBREF13 .\nWhile our point-of-departure is a standard word embedding model, we found that the off-the-shelf GloVe model performed surprisingly poorly, meaning that a number of modifications are needed to achieve good results. Our main findings are as follows. First, given that the number of tags associated with a given location can be quite small, it is important to apply some kind of spatial smoothing, i.e. the importance of a given tag for a given location should not only depend on the occurrences of the tag at that location, but also on its occurrences at nearby locations. To this end, we use a formulation which is based on spatially smoothed version of pointwise mutual information. Second, given the wide diversity in the kind of information that is covered by Flickr tags, we find that term selection is in some cases critical to obtain vector spaces that capture the relevant aspects of geographic locations. For instance, many tags on Flickr refer to photography related terms, which we would normally not want to affect the vector representation of a given location. Finally, even with these modifications, vector space embeddings learned from Flickr tags alone are sometimes outperformed by bag-of-words representations. However, our vector space embeddings lead to substantially better predictions in cases where structured (scientific) information is also taken into account. In this sense, the main value of using vector space embeddings in this context is not so much about abstracting away from specific tag usages, but rather about the fact that such representations allow us to integrate numerical and categorical features in a much more natural way than is possible with bag-of-words representations.\nThe remainder of this paper is organized as follows. In the next section, we provide a discussion of existing work. Section SECREF3 then presents our model for embedding geographic locations from Flickr tags and structured data. Next, in Section SECREF4 we provide a detailed discussion about the experimental results. Finally, Section SECREF5 summarizes our conclusions.\nOur main hypothesis in this paper is that by using vector space embeddings instead of bag-of-words representations, the ecological information which is implicitly captured by Flickr tags can be utilized in a more effective way. Vector space embeddings are representations in which the objects from a given domain are encoded using relatively low-dimensional vectors. They have proven useful in natural language processing, especially for encoding word meaning, and in machine learning more generally.

        "evidence": "Table 2 shows a comparison of the discussed settings on both SQuAD and TriviaQA. Without any fine-tuning (column 0) the performance is low, probably because the model never saw a real question, but we see significant gains with Cloze pretraining even with very little labeled data. The BiDAF+SA model, exceeds an F1 score of $50\\%$ with only $1\\%$ of the training data (454 questions for SQuAD, and 746 questions for TriviaQA), and approaches $90\\%$ of the best performance with only $10\\%$ labeled data. The gains over the SL setting, however, diminish as the size of the labeled set increases and are small when the full dataset is available.\nCloze pretraining outperforms the GDAN baseline from BIBREF0 using the same SQuAD dataset splits. Additionally, we show improvements in the $90\\%$ data case unlike GDAN. Our approach is also applicable in the extremely low-resource setting of $1\\%$ data, which we suspect GDAN might have trouble with since it uses the labeled data to do reinforcement learning. Furthermore, we are able to use the same cloze dataset to improve performance on both SQuAD and TriviaQA datasets. When we use the same unlabeled data to pre-train with a language modeling objective, the performance is worse, showing the bias we introduce by constructing clozes is important.\nOn the BioASQ dataset (Table 3 ) we again see a significant improvement when pretraining with the cloze questions over the supervised baseline. The improvement is smaller than what we observe with SQuAD and TriviaQA datasets – we believe this is because questions are generally more difficult in BioASQ. BIBREF14 showed that pretraining on SQuAD dataset improves the downstream performance on BioASQ. Here, we show a much larger improvement by pretraining on cloze questions constructed in an unsupervised manner from the same domain.\nWhen we use the same unlabeled data to pre-train with a language modeling objective, the performance is worse[Since the GA Reader uses bidirectional RNN layers, when pretraining the LM we had to mask the inputs to the in_x001f_termediate layers partially to avoid the model being exposed to the labels it is predicting.

Get two slices of bread, preferably not too thick; typical store-bought sliced bread like sourdough, potato, and white make adequate grilled bread.\n\nStep 3. While you are assembling the sandwich, heat a shallow pan over medium-low heat on your stovetop.\n\nStep 4. Spread some mayonnaise on the inside of each slice of bread. Sprinkle some garlic powder over the mayonnaise -- this gives a little extra flavor that one might not expect from a grilled cheese. \n\nStep 5. Layer the cheese between the slices of bread. Don't put too much cheese on it, or it will leak out of the sandwich when you cut it!\n\nStep 6. Assemble the sandwich and put a thin layer of mayo on the outside of each slice. \n\nStep 7. Lay the sandwich inside your heated pan. It should sizzle immediately. Wait two minutes and check to see if the cheese is melting. If the bread is browning too quickly, turn the heat down. When it is adequately browned on one side, use a spatula to flip it over to grill the other side.\n\nStep 8. Once your sandwich is grilled to your liking, turn off the stove and remove your sandwich from the pan. Slice diagonally and serve with a bowl of hot tomato soup. Enjoy!",

Alley produces “polite refusal” (2b) - the top ranked strategy - 31% of the time. Comparatively, commercial systems politely refuse only between 17% (Cortana) and 2% (Alexa). Most of the time commercial systems tend to “play along” (3a), joke (3b) or don't know how to answer (1e) which tend to receive lower ratings, see Figure FIGREF38. Rule-based systems most often politely refuse to answer (2b), but also use medium ranked strategies, such as deflect (2c) or chastise (2d). For example, most of Eliza's responses fall under the “deflection” strategy, such as “Why do you ask?”. Data-driven systems rank low in general. Neuralconvo and Cleverbot are the only ones that ever politely refuse and we attribute their improved ratings to this. In turn, the “clean” seq2seq often produces responses which can be interpreted as flirtatious (44%), and ranks similarly to Annabelle Lee and Laurel Sweet, the only adult bots that politely refuses ( 16% of the time). Ritter:2010:UMT:1857999.1858019's IR approach is rated similarly to Capt Howdy and both produce a majority of retaliatory (2e) responses - 38% and 58% respectively - followed by flirtatious responses.

Celebrity entrepreneurs, like Mark Cuban, talk about how they are learning to write code. Back in the late 1990s when I started getting paid to write code, this was not the case. I often found myself in windowless rooms, basements or chilly server rooms wrangling data or writing code. However, from early on in my career, my managers ensured that I was exposed to the real action: where the business value-add activities took place. I walked factory floors at Prestolite in Ann Arbor to see how the ERP system for which I was contributing programming code played a part in the convergence of IT with humans working with machines and parts to produce finished products. When I worked for Richard Helppie’s Superior Consultant Holdings Corporation, while between programming assignments, I shadowed an industrial engineer who was helping to redesign an Emergency Department’s (ED) physical layout; we watched the flow of doctors, patients and nurses. We asked questions like: “why are the doctors not using the stations intended for note-taking and instead are walking down two hallways to take their notes in empty offices?”; it turned out that the note-taking station in the heart of the ED was a place where doctors were exposed to all sorts of noise and other distractions.\n\nBeing a good programmer had a lot to do with understanding software architecture, APIs, etc… But being a better programmer meant understanding the world in which the software was actually put into practice. \n\nFord Motor Company’s F-150 has been America’s best selling truck for 46 consecutive years. Looking at the finished product with your eyes barely conveys the awesome complexity of the supply chain involved in bringing it to life. To get a better sense of the convergence of the F-150’s supply chain into its finished product, you can take a stroll on the catwalk that hovers above the assembly line as part of the Ford Rouge Factory Tour. The public can tour the plant and walk above a large portion of the assembly process. You can see Kanban in action as workers pull components from bins and perform their specialized task in a step of the ever-rolling line, while overhead displays help orchestrate replenishment. You can get a sense of the optimized flows of humans, robots and parts. And, maybe, if you look closely, you’ll spot opportunities for improvements in the process, in the safety measures, or in areas where automation has not yet taken hold. Consider whether or not you would see such opportunities by looking at charts and graphs…\n\nAlan Mulally was figuratively and literally a gymnast (at least during his time at the University of Kansas). After taking over the reins as CEO of Ford in 2006, he famously transformed a culture with deep-rooted divisional fiefdoms that hindered communication, reporting, efficiency and agility into a new era of quality, efficiency and innovation. A disciplined engineer by training, he did not solely rely on charts, facts and figures to drive organizational change. He used his eyes and made sure that the leaders saw the firm’s operations in a certain, methodical way. For instance, he built trust through transparency by using simple visual tools (like color-coding for status). \n\nOnce Mulally brought divisional leaders together to a conference room to look at a pile of hood prop rods for the various cars and trucks that Ford manufactures. The prop rods all looked different. They were from different suppliers, made of different materials, had a variety of costs, and had different internal staff dedicated to their role in the supply chain and assembly. He did not send a spreadsheet in an email to make his point. He had the leadership team look at the rods on the table and aimed for them to understand that “this kind of variation is costly but doesn’t matter to consumers.”\n\nMulally performed organizational and operational gymnastics, starting with a junk-rated company, and ending up being called “The Savior of Ford”. Mulally understood the power of seeing and of showing.\n\nIn the 1970s, Japan rocked the automotive world by mass producing high-quality, fuel-efficient vehicles at highly competitive prices. The Toyota way eventually swept across the industry, and a new jargon (and mindset) made its way to Detroit, with terms like Kaizen, Kanban, and Genchi Genbutsu. The Gemba Walk made its way into automotive manufacturing and other industries, such as Overhead Door and at the COVID-19 vaccination center at Mount Morningside Hospital in New York City. “The literal translation for Gemba (現場) is ‘the real place’ and in business it refers to the real place where value is created, such as the factory floor.” These tools are not a magic bullet; a Harvard Business Review study found that MBWA (“management by walking around”) decreased performance, on average, in a hospital setting. \n\nI used aspects of the Gemba Walk to help design a software system for lab technicians at a major national laboratory. When the CDC needed help to track the variants of the SARS-Cov-2 (“Coronavirus”) across the USA, I helped build a system that enabled lab technicians to efficiently select and route the appropriate samples for the genetic sequencing process, a step that comes after the COVID PCR test. I went to the lab, watched the technicians, observed the physical flow of humans and materials in the lab and talked with the people involved in the process. I was able to see (and measure) aspects of the process that I was tasked with automating. I made observations that I never could have made through video calls or emails.\n\nSoftware practitioners (developers, designers, architects, UX engineers and product owners) are continuously building and refining systems for robotics, assembly lines, labs, logistics, warehouses, shipyards, and other industries. “Agile” software development is a common methodology (and has some roots that are tied to Toyota-inspired manufacturing practices). Agile facilitates frequent, structured communication, but the product owner often serves as a proxy for the actual business stakeholders. He or she may communicate with slides, diagrams and customer “user stories”. However, as the value chain is communicated through the various parties (product owner, architect, etc.), the real-world value chain (what does the assembly line actually look like when it is in full swing) can become distilled and distorted.\n\nExecutives and senior managers are keenly monitoring the Work from Home (WFH) phenomenon. The U.S. Census Bureau is tracking WFH trends. Academics are analyzing WFH. Celebrity executives are flip-flopping on WFH. Productivity is questioned. But, are we asking the right question? Can you WFH and walk?\n\nIt is clear that IT and non-IT professionals prefer WFH… So companies are in a bind: force in-office work or find some middle ground. A.P. Moller – Maersk, “an integrated transport and logistics company”, lists job vacancies on their website. When looking at their IT jobs, you will struggle to see a mention of “Remote” or “Work from Home.” And you will also see vacancies, such as this Lead Software Engineer that have been open since May of 2022.\n\nA startup named “Gemba” is hoping to solve this vexing problem using Virtual Reality (VR). A Global Newswire article from January, 2023 describes Gemba’s origin story: “Gemba grew out of executive training company The Leadership Network, founded in 2013 by CEO Nathan Robinson and Chairman Victor Lewis. Through its collaboration with global giants like Toyota, Tesla, Google, BMW and Amazon, senior executives from non-competing companies have been able to visit their state-of-the-art factories and facilities to see best practice in action as part of an executive Gemba masterclass.”\n\nWe’ll see if technology will allow techies like myself to continue to work in our pajamas while getting the benefits of a Gemba Walk.

More recent Reinforcement Learning method for dialog generation BIBREF21 can also be applied to this task with slight modification. Future work will explore more complex, and unique models.\nSimilar to BIBREF21, a generative model is considered as an agent. However, different from dialog generation, generative intervention does not have multiple turns of utterance, so the action of the agent is to select a token in the response. The state of the agent is given by the input posts and the previously generated tokens. Another result due to this difference is that the rewards with regard to ease of answering or information flow do not apply to this case, but the reward for semantic coherence does. Therefore, the reward of the agent is:\nwhere $rw(c,r)$ is the reward with regard to the conversation $c$ and its reference response $r$ in the dataset. $p(r|c)$ denotes the probability of generating response $r$ given the conversation $c$, and $p_{back}(c|r)$ denotes the backward probability of generating the conversation based on the response, which is parameterized by another generation network. The reward is a weighted combination of these two parts, which are observed after the agent finishing generating the response. We refer the readers to BIBREF21 for details.\nThe encoder consists of 2 bidirectional GRU layers.",

        "question": "Why do some scholars think that campaigns do not matter much for presidential election outcomes? Why do other scholars and practitioners think that campaigns do matter?",
        "evidence": "",
        "answer": "Scholars argue that there are three main reasons that campaigns do not matter in elections.  One, that other factors have a greater influence than campaigns, such as if a candidate is an incumbent, party identification of the candidate, state of the economy, and finally, macro-trends like wars and presidential approval.  Second, the public does not care about politics so they don't pay attention to campaign functions like speeches, candidate gaffes, or advertising.  Third, in presidential elections, each side has about the same amount of experts and money which cancels out any advantage those resources might bring.\nOther scholars argue that campaigns do matter, and they also have three main reasons for this.  One, that after controlling for incumbency, campaign spending does impact a candidates performance. Secondly, Gerber and Green argue that campaigns personalized outreach, such as, door-to-door or digital contact, will influence the person contacted to go and vote for the candidate. Finally, for non-presidential elections, the campaign resources vary enormously between candidates and the campaign with the most resources is favored to win the election.",

        "answer": "By projecting these latent vectors through a parameterized non-linear function.",
        "evidence": "Data annotation is a major bottleneck for the application of supervised learning approaches to many problems. As a result, unsupervised methods that learn directly from unlabeled data are increasingly important. For tasks related to unsupervised syntactic analysis, discrete generative models have dominated in recent years – for example, for both part-of-speech (POS) induction BIBREF0 , BIBREF1 and unsupervised dependency parsing BIBREF2 , BIBREF3 , BIBREF4 . While similar models have had success on a range of unsupervised tasks, they have mostly ignored the apparent utility of continuous word representations evident from supervised NLP applications BIBREF5 , BIBREF6 . In this work, we focus on leveraging and explicitly representing continuous word embeddings within unsupervised models of syntactic structure.\nPre-trained word embeddings from massive unlabeled corpora offer a compact way of injecting a prior notion of word similarity into models that would otherwise treat words as discrete, isolated categories. However, the specific properties of language captured by any particular embedding scheme can be difficult to control, and, further, may not be ideally suited to the task at hand. For example, pre-trained skip-gram embeddings BIBREF7 with small context window size are found to capture the syntactic properties of language well BIBREF8 , BIBREF9 . However, if our goal is to separate syntactic categories, this embedding space is not ideal – POS categories correspond to overlapping interspersed regions in the embedding space, evident in Figure SECREF4 .\nIn our approach, we propose to learn a new latent embedding space as a projection of pre-trained embeddings (depicted in Figure SECREF5 ), while jointly learning latent syntactic structure – for example, POS categories or syntactic dependencies. To this end, we introduce a new generative model (shown in Figure FIGREF6 ) that first generates a latent syntactic representation (e.g. a dependency parse) from a discrete structured prior (which we also call the “syntax model”), then, conditioned on this representation, generates a sequence of latent embedding random variables corresponding to each word, and finally produces the observed (pre-trained) word embeddings by projecting these latent vectors through a parameterized non-linear function. The latent embeddings can be jointly learned with the structured syntax model in a completely unsupervised fashion.\nBy choosing an invertible neural network as our non-linear projector, and then parameterizing our model in terms of the projection's inverse, we are able to derive tractable exact inference and marginal likelihood computation procedures so long as inference is tractable in the underlying syntax model. In sec:learn-with-inv we show that this derivation corresponds to an alternate view of our approach whereby we jointly learn a mapping of observed word embeddings to a new embedding space that is more suitable for the syntax model, but include an additional Jacobian regularization term to prevent information loss.\nRecent work has sought to take advantage of word embeddings in unsupervised generative models with alternate approaches BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . BIBREF9 build an HMM with Gaussian emissions on observed word embeddings, but they do not attempt to learn new embeddings. BIBREF10 , BIBREF11 , and BIBREF12 extend HMM or dependency model with valence (DMV) BIBREF2 with multinomials that use word (or tag) embeddings in their parameterization. However, they do not represent the embeddings as latent variables.\nIn experiments, we instantiate our approach using both a Markov-structured syntax model and a tree-structured syntax model – specifically, the DMV. We evaluate on two tasks: part-of-speech (POS) induction and unsupervised dependency parsing without gold POS tags. Experimental results on the Penn Treebank BIBREF13 demonstrate that our approach improves the basic HMM and DMV by a large margin, leading to the state-of-the-art results on POS induction, and state-of-the-art results on unsupervised dependency parsing in the difficult training scenario where neither gold POS annotation nor punctuation-based constraints are available.\n\nTo this end, we introduce a new generative model (shown in Figure 2) that first generates a latent syntactic representation (e.g. a dependency parse) from a discrete structured prior (which we also call the “syntax model”), then, conditioned on this representation, generates a sequence of latent embedding random variables corresponding to each word, and finally produces the observed (pre-trained) word embeddings by projecting these latent vectors through a parameterized non-linear function.",

The product is made of a polymer which changes texture – firm in cold water and soft in warm water. As of 2019, Scrub Daddy had the highest revenue of any product successfully pitched on the ABC reality show Shark Tank.\n\nHistory\nAfter damaging the exterior of a vehicle when cleaning the outside, detailer Aaron Krause invented a line of buffing and polishing pads. The company was acquired by 3M in August 2008. 3M did not purchase a line of sponges Krause had invented, leaving them to sit in his factory. Five years later, Krause used the remaining sponges to clean his dishes and lawn furniture. According to Krause, this is when he \"realized his multi-million dollar idea.\"\n\nAccording to the company's website, Scrub Daddy, Inc. was founded in 2012 with grassroots marketing. On the Shark Tank episode originally airing in October 2012, Lori Greiner made a 20% equity stake deal with Krause for $200,000. The following day, Greiner and Krause sold out of 42,000 sponges in under seven minutes on QVC. Greiner then helped Scrub Daddy to be sold in retail stores such as Bed, Bath & Beyond. In January 2017, Scrub Daddy's total revenues surpassed $100 million – the highest of any Shark Tank product. As of October 2019, the company's lifetime sales were $209 million. In Season 14 Episode 13, it was reported that Scrub Daddy in 10 years has 273 employees, 160 products, sold in 257,000 retail locations, top 5 grossing company in shark tank history, doing over $670m in retail sales since launch.",

First, some believed that one of the series’ principal and most popular characters, Daenerys Targaryen, had been – if flawed – a protagonist throughout most of the series until the last few episodes of the final season, and her switch to a villainous persona felt rushed.  Similarly, some viewers believed that arcs for other main characters, including Jaime, Cersei, and Tyrion Lannister, Brienne of Tarth, Jon Snow, and others, were adversely impacted by the quick pacing of the final season and did away with much of those characters’ development over the course of many years.  Others were confused and disappointed that Bran Stark became king of the Seven Kingdoms (and ultimate winner of the titular “game of thrones”), as there seemed to be little build-up or motivation for that narrative decision.  Many suspect that George R.R. Martin, author of the “Song of Ice and Fire” series of novels on which the show was based, may have anticipated providing more narrative context and development for these choices in his then-unpublished final novels in the series, and that the television series simply needed to end well before Martin could complete his novels.",

The GC operations start at roughly one per minute and take less than five seconds each, but after 7:23 AM, they abruptly take about 30 seconds each and occur twice a minute. In other words, initially, GC operations take up a small fraction of the JVM time, while later, they take up almost all of its time.\n3. GC operations in this second period result in a very slight decrease in the total memory size and the PSYoungGen, ParOldGen, and Metaspace memory areas. This behavior is especially acute after 7:26:51 AM.\n4. This indicates much time spent in GC operations with little result.\n5. The total memory size initially slowly grows from 49.5GB to 52.3 GB, but in the second period maxes out at around 78 GB. \n6. The allocated memory size is fixed at 82 GB during the second period of GC operations, indicating an outer limit.\n7.

        "answer": "Yes, there are.",
        "evidence": "We applied this method to discover gender-associated words in both domains. In Table TABREF9, we present a sample of the most gender-associated nouns from the celebrity domain. Several themes emerge: for example, female celebrities seem to be more associated with appearance (“gown,” “photo,” “hair,” “look”), while male celebrities are more associated with creating content (“movie,” “film,” “host,” “director”). This echoes real-world trends: for instance, on the red carpet, actresses tend to be asked more questions about their appearance –- what brands they are wearing, how long it took to get ready, etc. –- while actors are asked questions about their careers and creative processes (as an example, see BIBREF31).\nTable TABREF9 also includes some of the most gender-associated verbs and adjectives from the professor domain. Female CS professors seem to be praised for being communicative and personal with students (“respond,” “communicate,” “kind,” “caring”), while male CS professors are recognized for being knowledgeable and challenging the students (“teach,”, “challenge,” “brilliant,” “practical”). These trends are well-supported by social science literature, which has found that female teachers are praised for “personalizing” instruction and interacting extensively with students, while male teachers are praised for using “teacher as expert” styles that showcase mastery of material BIBREF32.\nThese findings establish that there are clear differences in how people talk about women and men – even with Bonferroni correction, there are still over 500 significantly gender-associated nouns, verbs, and adjectives in the celebrity domain and over 200 in the professor domain. Furthermore, the results in both domains align with prior studies and real world trends, which validates that our methods can capture meaningful patterns and innovatively provide evidence at the large-scale. This analysis also hints that it can be helpful to abstract from words to topics to recognize higher-level patterns of gender associations, which motivates our next section on clustering.\nTable TABREF11 displays a sample of our results – we find that the clusters are coherent in context and the labels seem reasonable. In the next section, we discuss human evaluations that we conducted to more rigorously evaluate the output, but first we discuss the value of these methods toward analysis.\nAt the word-level, we hypothesized that in the celebrity domain, women were more associated with appearance and men with creating content. Now, we can validate those hypotheses against labeled clusters – indeed, there is a cluster labeled clothing that is 100% female (i.e. 100% words are female-associated), and a 80% male cluster labeled movie. Likewise, in the professor domain, we had guessed that women are associated with communication and men with knowledge, and there is a 100% female cluster labeled communication and a 89% male cluster labeled cognition. Thus, cluster labeling proves to be very effective at pulling out the patterns that we believed we saw at the word-level, but could not formally validate.\nThe clusters we mentioned so far all lean heavily toward one gender association or the other, but some clusters are interesting precisely because they do not lean heavily – this allows us to see where semantic groupings do not align exactly with gender association. For example, in the celebrity domain, there is a cluster labeled lover that has a mix of female-associated words (“boyfriend,” “beau,” “hubby”) and male-associated words (“wife,” “girlfriend”). Jointly leveraging cluster labels and gender associations allows us to see that in the semantic context of having a lover, women are typically associated with male figures and men with female figures, which reflects heteronormativity in society.\nThese findings establish that there are clear differences in how people talk about women and men – even with Bonferroni correction, there are still over 500 significantly gender-associated nouns, verbs, and adjectives in the celebrity domain and over 200 in the professor domain.",

Figure FIGREF6 displays the learned $\\sigma (w)$ embeddings for some input words, across the domains. To avoid cherry-picking the results, we chose the input words arbitrarily, subject to the following constraint. We considered each word to typically have a different syntactic category than the other choices from that domain. This constraint was used to present a diverse selection of words. Table TABREF5 displays the output behavior of models that we damaged to resemble the damage that causes aphasia. To avoid cherry-picking the results, we arbitrarily chose an input for each domain, subject to the following constraint. The input is not in the train set and the undamaged LLA-LSTM model produces a translation that we judge to be correct. For all inputs that we chose, damage to the analog of Broca's area (the LSTMs) results in an output that describes content only if it is described by the input. However, the output does not show understanding of the input's syntax. In the naturalistic domains, damage to the analog of Wernicke's area (the Lexicon Unit) results in an output with incorrect content that would be acceptable if the input had different words but the same syntax.

As such, an abstract is used by many organizations as the basis for selecting research that is proposed for presentation in the form of a poster, platform/oral presentation or workshop presentation at an academic conference. Most bibliographic databases only index abstracts rather than providing the entire text of the paper. Full texts of scientific papers must often be purchased because of copyright and/or publisher fees and therefore the abstract is a significant selling point for the reprint or electronic form of the full text. The abstract can convey the main results and conclusions of a scientific article but the full text article must be consulted for details of the methodology, the full experimental results, and a critical discussion of the interpretations and conclusions. An abstract allows one to sift through copious numbers of papers for ones in which the researcher can have more confidence that they will be relevant to their research. Once papers are chosen based on the abstract, they must be read carefully to be evaluated for relevance. It is generally agreed that one must not base reference citations on the abstract alone, but the content of an entire paper.",

        "question": "What criteria does the author use to evaluate translation performance?",
        "answer": "They use the standard BLEU score as the evaluation metric for translation performance.",
        "evidence": "To make the conclusion convincing, we first choose two large-scale datasets that are publicly available, i.e., Chinese-English and English-French. Since English, French, and Chinese all belong to the subject-verb-object (SVO) family, we choose another very different subject-object-verb (SOV) language, Japanese, which might bring some interesting linguistic behaviors in English-Japanese translation.\nFor Chinese-English task, we use WMT17 Chinese-English dataset that consists of $20.6$M sentence pairs. For English-French task, we use WMT14 English-French dataset that comprises $35.5$M sentence pairs. For English-Japanese task, we follow BIBREF17 to use the first two sections of WAT17 English-Japanese dataset that consists of $1.9$M sentence pairs. Following the standard NMT procedure, we adopt the standard byte pair encoding (BPE) BIBREF18 with 32K merge operations for all language pairs. We believe that these datasets are large enough to confirm the rationality and validity of our experimental analyses.\nWe choose the state-of-the-art Transformer BIBREF1 model and the conventional RNN-Search model BIBREF0 as our test bed. We implement the Attribution method based on the Fairseq-py BIBREF19 framework for the above models. All models are trained on the training corpus for 100k steps under the standard settings, which achieve comparable translation results. All the following experiments are conducted on the test dataset, and we estimate the input word importance using the model generated hypotheses.\nIn the following experiments, we compare IG (Attribution) with several black-box methods (i.e., Content, Frequency, Attention) as introduced in Section SECREF8. In Section SECREF21, to ensure that the translation performance decrease attributes to the selected words instead of the perturbation operations, we randomly select the same number of words to perturb (Random), which serves as a baseline. Since there is no ranking for content words, we randomly select a set of content words as important words. To avoid the potential bias introduced by randomness (i.e., Random and Content), we repeat the experiments for 10 times and report the averaged results. We calculate the Attention importance in a similar manner as the Attribution, except that the attention scores use a max operation due to the better performance.\nWe evaluate the effectiveness of estimating word importance by the translation performance decrease. More specifically, unlike the usual way, we measure the decrease of translation performance when perturbing a set of important words that are of top-most word importance in a sentence. The more translation performance degrades, the more important the word is.\nWe use the standard BLEU score as the evaluation metric for translation performance. To make the conclusion more convincing, we conduct experiments on different types of synthetic perturbations (Section SECREF21), as well as different NMT architectures and language pairs (Section SECREF27). In addition, we compare with a supervised erasure method, which requires ground-truth translations for scoring word importance (Section SECREF30).\nIn this experiment, we investigate the effectiveness of word importance estimation methods under different synthetic perturbations. Since the perturbation on text is notoriously hard BIBREF20 due to the semantic shifting problem, in this experiment, we investigate three types of perturbations to avoid the potential bias :\nDeletion perturbation removes the selected words from the input sentence, and it can be regarded as a specific instantiation of sentence compression BIBREF21.\nMask perturbation replaces embedding vectors of the selected words with all-zero vectors BIBREF22, which is similar to Deletion perturbation except that it retains the placeholder.\nGrammatical Replacement perturbation replaces a word by another word of the same linguistic role (i.e., POS tags), yielding a sentence that is grammatically correct but semantically nonsensical BIBREF23, BIBREF24, such as “colorless green ideas sleep furiously”.\nFigure FIGREF19 illustrates the experimental results on Chinese$\\Rightarrow $English translation with Transformer. It shows that Attribution method consistently outperforms other methods against different perturbations on a various number of operations. Here the operation number denotes the number of perturbed words in a sentence. Specifically, we can make the following observations.\nUnder three different perturbations, perturbing words of top-most importance leads to lower BLEU scores than Random selected words. It confirms the existence of important words, which have greater impacts on translation performance. Furthermore, perturbing important words identified by Attribution outperforms the Random method by a large margin (more than 4.0 BLEU under 5 operations).\nFigure FIGREF19 shows that two black-box methods (i.e., Content, Frequency) perform only slightly better than the Random method. Specifically, the Frequency method demonstrates even worse performances under the Mask perturbation. Therefore, linguistic properties (such as POS tags) and the word frequency can only partially help identify the important words, but it is not as accurate as we thought. In the meanwhile, it is intriguing to explore what exact linguistic characteristics these important words reveal, which will be introduced in Section SECREF5.\nWe also evaluate the Attention method, which bases on the encoder-decoder attention scores at the last layer of Transformer. Note that the Attention method is also used to simulate the best black-box method SOCRAT, and the results show that it is more effective than black-box methods and the Random baseline. Given the powerful Attention method, Attribution method still achieves best performances under all three perturbations. Furthermore, we find that the gap between Attribution and Attention is notably large (around $1.0+$ BLEU difference). Attention method does not provide as accurate word importance as the Attribution, which exhibits the superiority of gradient-based methods and consists with the conclusion reported in the previous study BIBREF8.\nIn addition, as shown in Figure FIGREF19, the perturbation effectiveness of Deletion, Mask, and Grammatical Replacement varies from strong to weak. In the following experiments, we choose Mask as the representative perturbation operation for its moderate perturbation performance, based on which we compare two most effective methods Attribution and Attention.\nWe validate the effectiveness of the proposed approach using a different NMT architecture RNN-Search on the Chinese$\\Rightarrow $English translation task. The results are shown in Figure FIGREF20(a). We observe that the Attribution method still outperforms both Attention method and Random method by a decent margin. By comparing to Transformer, the results also reveal that the RNN-Search model is less robust to these perturbations. To be specific, under the setting of five operations and Attribution method, Transformer shows a relative decrease of $55\\%$ on BLEU scores while the decline of RNN-Search model is $64\\%$.\nWe further conduct experiments on another two language pairs (i.e., English$\\Rightarrow $French, English$\\Rightarrow $Japanese in Figures FIGREF20(b, c)) as well as the reverse directions (Figures FIGREF20(d, e, f)) using Transformer under the Mask perturbation. In all the cases, Attribution shows the best performance while Random achieves the worst result. More specifically, Attribution method shows similar translation quality degradation on all three language-pairs, which declines to around the half of the original BLEU score with five operations.\nThere exists another straightforward method, Erasure BIBREF7, BIBREF22, BIBREF25, which directly evaluates the word importance by measuring the translation performance degradation of each word. Specifically, it erases (i.e., Mask) one word from the input sentence each time and uses the BLEU score changes to denote the word importance (after normalization).\nIn Figure FIGREF31, we compare Erasure method with Attribution method under the Mask perturbation. The results show that Attribution method is less effective than Erasure method when only one word is perturbed. But it outperforms the Erasure method when perturbing 2 or more words. The results reveal that the importance calculated by erasing only one word cannot be generalized to multiple-words scenarios very well. Besides, the Erasure method is a supervised method which requires ground-truth references, and finding a better words combination is computation infeasible when erasing multiple words.\nWe close this section by pointing out that our gradient-based method consistently outperforms its black-box counterparts in various settings, demonstrating the effectiveness and universality of exploiting gradients for estimating word importance. In addition, our approach is on par with or even outperforms the supervised erasure method (on multiple-word perturbations). This is encouraging since our approach does not require any external resource and is fully unsupervised.\nWe use the standard BLEU score as the evaluation metric for translation performance.",

Although Chisholm and Godley Chisholm:11 and we found relations between our coding constructs and discussion quality, these were small-scale studies based on manual annotations. Once automated classifiers are developed, such relations between talk and learning can be examined at scale. Also, automatic labeling via a standard coding scheme can support the generalization of findings across studies, and potentially lead to automated tools for teachers and students.\nThe proposed annotation scheme also introduces NLP opportunities and challenges. Existing systems for classifying specificity and argumentation have largely been designed to analyze written text rather than spoken discussions. This is (at least in part) due to a lack of publicly available corpora and schemes for annotating argumentation and specificity in spoken discussions. The development of an annotation scheme explicitly designed for this problem is the first step towards collecting and annotating corpora that can be used by the NLP community to advance the field in this particular area. Furthermore, in text-based discussions, NLP methods need to tightly couple the discussion with contextual information (i.e., the text under discussion). For example, an argument move from one of the discussions mentioned in Section 4 stated “She's saying like free like, I don't have to be, I don't have to be this salesman's wife anymore, your know? I don't have to play this role anymore.\" The use of the term salesman shows the presence of specificity element (3) (see Section 3.2) because the text under discussion is indeed Death of a Salesman. If the students were discussing another text, the mention of the term salesman would not indicate one of the specificity elements, therefore lowering the specificity rating. Thus, using existing systems is unlikely to yield good performance. In fact, we previously BIBREF31 showed that while using an off-the-shelf system for predicting specificity in newspaper articles resulted in low performance when applied to classroom discussions, exploiting characteristics of our data could significantly improve performance. We have similarly evaluated the performance of two existing argument mining systems BIBREF18 , BIBREF33 on the transcripts described in Section SECREF4 . We noticed that since the two systems were trained to classify only claims and premises, they were never able to correctly predict warrants in our transcripts. Additionally, both systems classified the overwhelming majority of moves as premise, resulting in negative kappa in some cases. Using our scheme to create a corpus of classroom discussion data manually annotated for argumentation, specificity, and knowledge domain will support the development of more robust NLP prediction systems.\nOur annotation scheme introduces opportunities for the educational community to conduct further research on the relationship between features of student talk, student learning, and discussion quality.\nOnce automated classifiers are developed, such relations between talk and learning can be examined at scale.

        "evidence": "Suppose a user wants to write a sentence “I will be 10 minutes late.” Ideally, she would type just a few keywords such as “10 minutes late” and an autocomplete system would be able to infer the intended sentence (Figure FIGREF1). Existing left-to-right autocomplete systems BIBREF0, BIBREF1 can often be inefficient, as the prefix of a sentence (e.g. “I will be”) fails to capture the core meaning of the sentence. Besides the practical goal of building a better autocomplete system, we are interested in exploring the tradeoffs inherent to such communication schemes between the efficiency of typing keywords, accuracy of reconstruction, and interpretability of keywords.\nOne approach to learn such schemes is to collect a supervised dataset of keywords-sentence pairs as a training set, but (i) it would be expensive to collect such data from users, and (ii) a static dataset would not capture a real user's natural predilection to adapt to the system BIBREF2. Another approach is to avoid supervision and jointly learn a user-system communication scheme to directly optimize the combination of efficiency and accuracy. However, learning in this way can lead to communication schemes that are uninterpretable to humans BIBREF3, BIBREF4 (see Appendix for additional related work).\nIn this work, we propose a simple, unsupervised approach to an autocomplete system that is efficient, accurate, and interpretable. For interpretability, we restrict keywords to be subsequences of their source sentences based on the intuition that humans can infer most of the original meaning from a few keywords. We then apply multi-objective optimization approaches to directly control and achieve desirable tradeoffs between efficiency and accuracy.\nWe observe that naively optimizing a linear combination of efficiency and accuracy terms is unstable and leads to suboptimal schemes. Thus, we propose a new objective which optimizes for communication efficiency under an accuracy constraint. We show this new objective is more stable and efficient than the linear objective at all accuracy levels.\nAs a proof-of-concept, we build an autocomplete system within this framework which allows a user to write sentences by specifying keywords. We empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences. Finally, we demonstrate that humans can easily adapt to the keyword-based autocomplete system and save nearly 50% of time compared to typing a full sentence in our user study.\nWe empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences.",

As indicated in Sec. 2.1, the method takes a victim classifier v, an input image x in , and a norm bound ν. The projection operator Π xin,ν confines its input to the ν-ball centred on x in : its inclusion in the algorithm represents a standard projected gradient ascent (PGA) implementation. Additionally, the method requires a loss function L, a set S of one or more surrogate models, and a step length ϵ representing the fixed length of the perturbations to be attempted at each iterate 1 along its candidate direction. The loss L can be any function of the iterate that serves as a suitable proxy for the adversarial objective, as in Sec. 2.1:\nthe only requirement here is that it be once differentiable. In our implementation, we make the popular and effective choice of the margin loss L f (x) = f ct (x) − f cs (x) where c s = argmax c v c (x) and c t = argmax c̸ =cs v c (x), i.e. the difference between the highest and second-highest (or, in the targeted case, the target) class scores. Note that the class IDs c t and c s are defined by the ranking according to v, but are evaluated on the net f parametrising the loss, which is either s or v depending on the line of the algorithm (9 and 15, respectively). The natural assumption of a surrogate method is that the surrogate will provide useful information about the victim, but there is no \"hard\" requirement on the surrogates s ∈ S other than being once-differentiable functions mapping X → Y. The definition of ODS direction d ODS for network f and input x is, as in,\nwhere w is sampled from the uniform distribution over [−1, 1] C . By definition, it is the normalised gradient of a randomly weighted sum of all of the class scores. Equivalently, by linearity, it is a randomly weighted sum of all of the class-score gradients (i.e. rows of the Jacobian matrix), which are themselves a basis of the coimage of the linear approximation of f : the subspace which f exhibits any nonzero response to.\nAs indicated in Sec. 1, the logic of the method is simple. At any given iterate, the method tries to proceed in a SimBA-like manner by testing the change in adversarial loss at fixed-length steps along candidate directions, projected back into the feasible set where necessary. It does so exclusively using normalised loss gradients from the surrogates in the input set (drawn in random order, without replacement), unless and until it has exhausted them at that iterate without success. As we will demonstrate in Sec. 3.2, this intermediate failure state is seldom reached. If this state is reached, however, the method instead randomly samples a surrogate (with replacement) and an ODS direction from that surrogate, attempting a SimBA update each time, until an improvement in the loss is realised. Once such a successful update occurs, the method resets the candidate surrogate set to the input set and resumes using normalised loss gradients only. The method terminates on finding an adversarial example or on exceeding an upper bound on the query count if one has been specified.). The latter is omitted for LeBA , which does not admit non-singleton surrogate sets. All networks used are pretrained models available via PyTorch/torchvision. Parameter values of competitors are as they specify except where we note otherwise for reasons that will be discussed below. LeBA is run in \"train\" mode on a held-out set of 1000 images and then evaluated in \"test\" mode on the same set of 2000 used for all other methods. P-RGF always uses the adaptive coefficient mode. P-RGF and ODS-RGF are based on our own PyTorch port of the reference P-RGF code, which will be released along with this paper: no public implementation of ODS-RGF currently exists otherwise. We include the surrogate-free for comparison.\nTo delve deeper into the results of Sec. 3.1, we plot each attacked example as a 2D point whose x-coordinate is the number of queries expended by the surrogate loss gradient block of the algorithm, and whose y-coordinate is the analogous count for the coimage block. This gives the scatter plot of Fig., which is supplemented by marginal histograms corresponding to the axes opposite them. The figure shows results obtained using Inception-v3 as the victim: see Appendix A.3 for analogous figures for VGG-16 and ResNet-50. Note that the axes of the main scatter plots are log-log, while those of the marginal histograms are linear-log. Some phenomena are readily evident. For one, there is a large fraction of examples (represented by the dense horizontal rows of dots at the bottom of the plots) that succeed within a very low number of queries (on the order of 1-10), which are entirely or almost entirely due to the surrogate gradient transfer, with ODS used seldom or not at all. As these low-query clusters are extremely dense, the corresponding marginals should be consulted (best under zoom) in order to quantify them. For another, the number of examples outside of this regime falls considerably when the four-surrogate set is used instead of ResNet-152 on its own, as can be seen by comparing the left and right sides of the figure. It is clear that the examples that rely on the interplay between the gradient-and coimage-based direction generators are reduced to a nontrivial (i.e. sufficient to affect the failure rate if not handled) but nonetheless relatively small group. Overall, there is an order-of-magnitude difference between surrogate loss gradient queries and ODS queries in the points extending away from the dense low-query cluster at the bottom, i.e. the examples that rely on both submethods. That is, when the ODS block is required, it typically requires far more queries to progress the optimiser than in the much more common cases in which the gradient suffices.\nits inclusion in the algorithm represents a standard projected gradient ascent (PGA) implementation.",

        "question": "Do the authors analyze the strengths and limitations of character-level models compared to morphology?",
        "answer": "Yes, they do.",
        "evidence": "Encoding of words is perhaps the most important step towards a successful end-to-end natural language processing application. Although word embeddings have been shown to provide benefit to such models, they commonly treat words as the smallest meaning bearing unit and assume that each word type has its own vector representation. This assumption has two major shortcomings especially for languages with rich morphology: (1) inability to handle unseen or out-of-vocabulary (OOV) word-forms (2) inability to exploit the regularities among word parts. The limitations of word embeddings are particularly pronounced in sentence-level semantic tasks, especially in languages where word parts play a crucial role. Consider the Turkish sentences “Köy+lü-ler (villagers) şehr+e (to town) geldi (came)” and “Sendika+lı-lar (union members) meclis+e (to council) geldi (came)”. Here the stems köy (village) and sendika (union) function similarly in semantic terms with respect to the verb come (as the origin of the agents of the verb), where şehir (town) and meclis (council) both function as the end point. These semantic similarities are determined by the common word parts shown in bold. However ortographic similarity does not always correspond to semantic similarity. For instance the ortographically similar words knight and night have large semantic differences. Therefore, for a successful semantic application, the model should be able to capture both the regularities, i.e, morphological tags and the irregularities, i.e, lemmas of the word.\nMorphological analysis already provides the aforementioned information about the words. However access to useful morphological features may be problematic due to software licensing issues, lack of robust morphological analyzers and high ambiguity among analyses. Character-level models (CLM), being a cheaper and accessible alternative to morphology, have been reported as performing competitively on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 . However the extent to which these tasks depend on morphology is small; and their relation to semantics is weak. Hence, little is known on their true ability to reveal the underlying morphological structure of a word and their semantic capabilities. Furthermore, their behaviour across languages from different families; and their limitations and strengths such as handling of long-range dependencies, reaction to model complexity or performance on out-of-domain data are unknown. Analyzing such issues is a key to fully understanding the character-level models.\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:\n $[$ Villagers $]$ comers came $[$ to town $]$ end point\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis. The gold morphology serves as the upper bound for us to compare and analyze the performances of character-level models on languages of varying morphological typologies. We carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology. In regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English. Our experiments and analysis reveal insights such as:\nWe carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology.",

        "evidence": "Generating descriptions for multimedia contents such as images and videos, so called Image Captioning, is helpful for e-commerce companies or news agencies. For instance, in e-commerce field, people will no longer need to put much effort into understanding and describing products' images on their websites because image contents can be recognized and descriptions are automatically generated. Inspired by Horus BIBREF0 , Image Captioning system can also be integrated into a wearable device, which is able to capture surrounding images and generate descriptions as sound in real time to guide people with visually impaired.\nImage Captioning has attracted attentions from researchers in recent years BIBREF1, BIBREF2, BIBREF3, and there has been promising attempts dealing with language barrier in this task by extending existed dataset captions into different languages BIBREF3, BIBREF4.\nIn this study, generating image captions in Vietnamese language is put into consideration. One straightforward approach for this task is to translate English captions into Vietnamese by human or by using machine translation tool, Google translation. With the method of translating directly from English to Vietnamese, we found that the descriptions are sometimes confusing and unnatural to native people. Moreover, image understandings are cultural dependent, as in Western, people usually have different ways to grasp images and different vocabulary choices for describing contexts. For instance, in Fig. FIGREF2, one MS-COCO English caption introduce about \"a baseball player in motion of pitching\", which makes sense and capture accurately the main activity in the image. Though it sounds sensible in English, the sentence becomes less meaningful when we try to translate it into Vietnamese. One attempt of translating the sentence is performed by Google Translation, and the result is not as expected.\n\n\nTherefore, we come up with the approach of constructing a Vietnamese Image Captioning dataset with descriptions written manually by human. Composed by Vietnamese people, the sentences would be more natural and friendlier to Vietnamese users. The main resources we used from MS-COCO for our dataset are images. Besides, we consider having our dataset focus on sportball category due to several reasons:\nBy concentrating on a specific domain we are more likely to improve performance of the Image Captioning models. We expect our dataset can be used to confirm or reject this hypothesis.\nSportball Image Captioning can be used in certain sport applications, such as supportting journalists describing great amount of images for their articles.\nOur primary contributions of this paper are as follows:\nFirstly, we introduce UIT-ViIC, the first Vietnamese dataset extending MS-COCO with manually written captions for Image Captioning. UIT-ViIC is published for research purposes.\nSecondly, we introduce our annotation tool for dataset construction, which is also published to help annotators conveniently create captions.\nFinally, we conduct experiments to evaluate state-of-the-art models (evaluated on English dataset) on UIT-ViIC dataset, then we analyze the performance results to have insights into our corpus.\nThe structure of the paper is organized as follows. Related documents and studies are presented in Section SECREF2. UIT-ViIC dataset creation is described in Section SECREF3. Section SECREF4 describes the methods we implement. The experimental results and analysis are presented in Section SECREF5.

        "answer": "The authors performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.",
        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31. Besides, when node B retweets node A we have an implicit confirmation that information from A appeared in B's Twitter feed BIBREF12. Quotes are simply a special case of retweets with comments.\nMentions usually include personal conversations as they allow someone to address a specific user or to refer to an individual in the third person; in the first case they are located at the beginning of a tweet and they are known as replies, otherwise they are put in the body of a tweet BIBREF20. The network of mentions is usually seen as a stronger version of interactions between Twitter users, compared to the traditional graph of follower/following relationships BIBREF32.\nIn order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.",

        "evidence": "Word Sense Disambiguation (WSD) is an important problem in Natural Language Processing (NLP), both in its own right and as a stepping stone to other advanced tasks in the NLP pipeline, applications such as machine translation BIBREF0 and question answering BIBREF1 . WSD specifically deals with identifying the correct sense of a word, among a set of given candidate senses for that word, when it is presented in a brief narrative (surrounding text) which is generally referred to as context. Consider the ambiguous word `cold'. In the sentence “He started to give me a cold shoulder after that experiment”, the possible senses for cold can be cold temperature (S1), a cold sensation (S2), common cold (S3), or a negative emotional reaction (S4). Therefore, the ambiguous word cold is specified along with the sense set {S1, S2, S3, S4} and our goal is to identify the correct sense S4 (as the closest meaning) for this specific occurrence of cold after considering - the semantic and the syntactic information of - its context.\nIn this effort, we develop our supervised WSD model that leverages a Bidirectional Long Short-Term Memory (BLSTM) network. This network works with neural sense vectors (i.e. sense embeddings), which are learned during model training, and employs neural word vectors (i.e. word embeddings), which are learned through an unsupervised deep learning approach called GloVe (Global Vectors for word representation) BIBREF2 for the context words. By evaluating our one-model-fits-all WSD network over the public gold standard dataset of SensEval-3 BIBREF3 , we demonstrate that the accuracy of our model in terms of F-measure is comparable with the state-of-the-art WSD algorithms'.\nWe outline the organization of the rest of the paper as follows. In Section 2, we briefly explore earlier efforts in WSD and discuss recent approaches that incorporate deep neural networks and word embeddings.

We then present our experiments and results in Section 4 supported by a discussion on how to avoid some drawbacks of the current model in order to achieve higher accuracies and demand less number of training data which is desirable. Finally, in Section 5, we conclude with some future research directions for the construction of sense embeddings as well as applications of such model in other domains such as biomedicine.\nBy evaluating our one-model-fits-all WSD network over the public gold standard dataset of SensEval-3 , we demonstrate that the accuracy of our model in terms of F-measure is comparable with the state-of-the-art WSD algorithms'.",

        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nIt significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic trans lation' based on Damerau-Levenshtein distance, even en riched with dictionary mappings.",

        "answer": "Asperger syndrome (AS), or Asperger's, is a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior and interests. The syndrome is no longer recognized as a diagnosis, having been merged with other conditions into autism spectrum disorder (ASD). It was considered to differ from other diagnoses that were incorporated into ASD by relatively unimpaired spoken language and intelligence.\n\nThe syndrome was named after the Austrian pediatrician Hans Asperger, who, in 1944, described children in his care who struggled to form friendships, did not understand others’ gestures or feelings, engaged in one-sided conversations about their favorite interests, and were clumsy. In 1994, the diagnosis of Asperger's was included in the fourth edition (DSM-IV) of the American Diagnostic and Statistical Manual of Mental Disorders; however, with the publication of DSM-5 in 2013, the syndrome was removed, and the symptoms are now included within autism spectrum disorder along with classic autism and pervasive developmental disorder not otherwise specified (PDD-NOS). It was similarly merged into autism spectrum disorder in the International Classification of Diseases (ICD-11) as of 2021.\n\nThe exact cause of Asperger's is poorly understood. While it has high heritability, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role. Brain imaging has not identified a common underlying condition. There is no single treatment, and the UK's National Health Service (NHS) guidelines suggest that ’treatment’ of any form of autism should not be a goal since autism is not an 'a disease that can be removed or cured’. According to the Royal College of Psychiatrists, while co-occurring conditions might require treatment, ’management of autism itself is chiefly about providing the education, training and social support/care required to improve the person's ability to function in the everyday world’. Only limited data support the effectiveness of particular interventions for autism. Interventions may include social skills training, cognitive behavioral therapy, physical therapy, speech therapy, parent training, and medications for associated problems, such as mood or anxiety.

        "evidence": "While the LSTM encoder has richer capacity than NBOW, it produces the same representation for the entire text description regardless of its contexts. However, the text description may present an entity from various aspects, and various relations only focus on fractional aspects of the description.

Some of them may be important for the given relation, but may be useless for other relations. Therefore, we introduce an attention mechanism BIBREF20 to utilize an attention-based encoder that constructs contextual text encodings according to different relations.\nFor each position $i$ of the text description, the attention for a given relation $r$ is defined as $\\alpha _i(r)$ , which is \n$$e_i(r) &= \\mathbf {v}_a^T \\tanh (\\mathbf {W}_a {\\mathbf {z}}_i + \\mathbf {U}_a \\mathbf {r}), \\\\\n\\alpha _i(r)&=\\operatorname{\\mathbf {softmax}}(e_i(r))\\nonumber \\\\\n&=\\frac{\\exp (e_i(r))}{\\sum ^{n}_{j=1} \\exp (e_j(r))},$$   (Eq. 12) \n where $\\mathbf {r}\\in \\mathbb {R}^d$ is the relation embedding; ${\\mathbf {z}}_i \\in \\mathbb {R}^d$ is the output of BLSTM at position $i$ ; $\\mathbf {W}_a,\\mathbf {U}_a \\in \\mathbb {R}^{d\\times d}$ are parameters matrices; $\\mathbf {v}_a \\in \\mathbb {R}^{d}$ is a parameter vector.\nThe attention $\\alpha _i(r)$ is interpreted as the degree to which the network attends to partial representation $\\mathbf {z}_{i}$ for given relation $r$ .\nThe contextual encoding of text description can be formed by a weighted sum of the encoding $\\mathbf {z}_{i}$ with attention. \n$$\\mathbf {enc_3}(x_{1:n};r) &= \\sum _{i=1}^{n} \\alpha _i(r) * \\mathbf {z}_i.$$   (Eq. 13) \nGiven a relation for an entity, not all of words/phrases in its text description are useful to model a specific fact.

Selection-based QA implies a family of tasks that find answer contexts from large data given questions in natural language. Three tasks have been proposed for selection-based QA. Given a document, answer extraction BIBREF0 , BIBREF1 finds answer phrases whereas answer selection BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 and answer triggering BIBREF6 , BIBREF7 find answer sentences instead, although the presence of the answer context is not assumed within the provided document for answer triggering but it is for the other two tasks. Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension. Finally, morales-EtAl:2016:EMNLP2016 provided InfoboxQA for answer selection.\nThese corpora make it possible to evaluate the robustness of statistical question answering learning. Although all of these corpora target on selection-based QA, they are designed for different purposes such that it is important to understand the nature of these corpora so a better use of them can be made. In this paper, we make both intrinsic and extrinsic analyses of four latest corpora based on Wikipedia, WikiQA, SelQA, SQuAD, and InfoboxQA. We first give a thorough intrinsic analysis regarding contextual similarities, question types, and answer categories (Section SECREF2 ). We then map questions in all corpora to the current version of English Wikipedia and benchmark another selection-based QA task, answer retrieval (Section SECREF3 ).

        "evidence": "",
        "answer": "These two games are both played with a frisbee (or \"disc\"), which is a plastic disc that people throw through the air like a ball. The difference is that ultimate frisbee is a team sport that combines several of the rules of football, basketball and soccer. Like football, a team takes possession of the frisbee and tries to move it down field and into an end zone. Like basketball, once you are in possession of the frisbee, you cannot move your pivot foot. However, there is no \"dribbling\" with a frisbee so if a player has possession of the frisbee outside of their end zone, they have to pass it before they can move their pivot foot. Ultimate frisbee is played on a soccer field and the player movement looks most like that sport. Frisbee golf, on the other hand, follows the rules of golf, except that the player throws a frisbee to the hole instead of hitting a ball with clubs. Some people play the sport on dedicated frisbee golf courses, using a set of specialized discs of various weights and carrying them in a bag from hole to hole like a golfer would do with their set of clubs. Others simply take a standard 175-gram frisbee and make up a course as they go.

        "evidence": "Encoding of words is perhaps the most important step towards a successful end-to-end natural language processing application. Although word embeddings have been shown to provide benefit to such models, they commonly treat words as the smallest meaning bearing unit and assume that each word type has its own vector representation. This assumption has two major shortcomings especially for languages with rich morphology: (1) inability to handle unseen or out-of-vocabulary (OOV) word-forms (2) inability to exploit the regularities among word parts. The limitations of word embeddings are particularly pronounced in sentence-level semantic tasks, especially in languages where word parts play a crucial role. Consider the Turkish sentences “Köy+lü-ler (villagers) şehr+e (to town) geldi (came)” and “Sendika+lı-lar (union members) meclis+e (to council) geldi (came)”. Here the stems köy (village) and sendika (union) function similarly in semantic terms with respect to the verb come (as the origin of the agents of the verb), where şehir (town) and meclis (council) both function as the end point. These semantic similarities are determined by the common word parts shown in bold. However ortographic similarity does not always correspond to semantic similarity. For instance the ortographically similar words knight and night have large semantic differences. Therefore, for a successful semantic application, the model should be able to capture both the regularities, i.e, morphological tags and the irregularities, i.e, lemmas of the word.\nMorphological analysis already provides the aforementioned information about the words. However access to useful morphological features may be problematic due to software licensing issues, lack of robust morphological analyzers and high ambiguity among analyses. Character-level models (CLM), being a cheaper and accessible alternative to morphology, have been reported as performing competitively on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 . However the extent to which these tasks depend on morphology is small; and their relation to semantics is weak. Hence, little is known on their true ability to reveal the underlying morphological structure of a word and their semantic capabilities. Furthermore, their behaviour across languages from different families; and their limitations and strengths such as handling of long-range dependencies, reaction to model complexity or performance on out-of-domain data are unknown. Analyzing such issues is a key to fully understanding the character-level models.\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:\n $[$ Villagers $]$ comers came $[$ to town $]$ end point\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis. The gold morphology serves as the upper bound for us to compare and analyze the performances of character-level models on languages of varying morphological typologies. We carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology. In regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English. Our experiments and analysis reveal insights such as:\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English.",

At the time, most children's toy dolls were representations of infants. Realizing that there could be a gap in the market, Handler suggested the idea of an adult-bodied doll to her husband Elliot, a co-founder of the Mattel toy company. He was unenthusiastic about the idea, as were Mattel's directors.\n\nDuring a trip to Europe in 1956 with her children Barbara and Kenneth, Ruth Handler came across a German toy doll called Bild Lilli. The adult-figured doll was exactly what Handler had in mind, so she purchased three of them. She gave one to her daughter and took the others back to Mattel. The Lilli doll was based on a popular character appearing in a comic strip drawn by Reinhard Beuthin for the newspaper Bild. Lilli was a blonde bombshell, a working girl who knew what she wanted and was not above using men to get it. The Lilli doll was first sold in Germany in 1955, and although it was initially sold to adults, it became popular with children who enjoyed dressing her up in outfits that were available separately.",

It was used in the ancient Near East, Europe, China, and Russia, millennia before the adoption of the Hindu-Arabic numeral system. The exact origin of the abacus has not yet emerged. It consists of rows of movable beads, or similar objects, strung on a wire. They represent digits. One of the two numbers is set up, and the beads are manipulated to perform an operation such as addition, or even a square or cubic root.\n\nIn their earliest designs, the rows of beads could be loose on a flat surface or sliding in grooves. Later the beads were made to slide on rods and built into a frame, allowing faster manipulation. Abacuses are still made, often as a bamboo frame with beads sliding on wires. In the ancient world, particularly before the introduction of positional notation, abacuses were a practical calculating tool. The abacus is still used to teach the fundamentals of mathematics to some children, for example, in Russia.",

        "question": "How to express the statements in RDF?",
        "answer": "Statements in RDF are expressed as so-called triples of the form (subject, predicate, object).",
        "evidence": "RDF BIBREF18 uses a graph-based data model for representing knowledge. Statements in RDF are expressed as so-called triples of the form (subject, predicate, object). RDF subjects and predicates are IRI and objects are either IRI or literals. RDF literals always have a datatype that defines its possible values. A predicate denotes a property and can also be seen as a binary relation taking subject and object as arguments. For example, the following triple expresses that Albert Einstein was born in Ulm:\nThe lexicalization of RDF triples must be able to deal with resources, classes, properties and literals.\nClasses and resources The lexicalization of classes and resources is carried out as follows: Given a URI $u$ we ask for the English label of $u$ using a SPARQL query. If such a label does not exist, we use either the fragment of $u$ (the string after #) if it exists, else the string after the last occurrence of /. Finally this NL representation is realized as a noun phrase, and in the case of classes is also pluralized. As an example, :Person is realized as people (its label).\nProperties The lexicalization of properties relies on the insight that most property labels are either nouns or verbs. While the mapping of a particular property p can be unambiguous, some property labels are not as easy to categorize. For examples, the label crosses can either be the plural form of the noun cross or the third person singular present form of the verb to cross. To automatically determine which realization to use, we relied on the insight that the first and last word of a property label are often the key to determining the type of the property: properties whose label begins with a verb (resp. noun or gerund) are most to be realized as verbs (resp. nouns). We devised a set of rules to capture this behavior, which we omit due to space restrictions. In some cases (such as crosses) none of the rules applied. In these cases, we compare the probability of $P(p|\\texttt {noun})$ and $P(p|\\texttt {verb})$ by measuring\nwhere $\\text{\\em synset}(p)$ is the set of all synsets of $p$, $\\text{\\em synset}(p|X)$ is the set of all synsets of $p$ that are of the syntactic class $X \\in \\lbrace \\texttt {noun},\\texttt {verb}\\rbrace $ and $f(t)$ is the frequency of use of $p$ in the sense of the synset $t$ according to WordNet. For\nwe choose to realize p as a noun; else we realized it as a verb. For $\\theta =1$, for example, dbo:crosses is realized as a verb.\nLiterals Literals in an RDF graph usually consist of a lexical form LF and a datatype IRI DT, represented as \"LF\"⌃⌃<DT>. Optionally, if the datatype is rdf:langString, a non-empty language tag is specified and the literal is denoted as language-tagged string. The realization of language-tagged strings is done by using simply the lexical form, while omitting the language tag. For example, \"Albert Einstein\"@en is realized as Albert Einstein. For other types of literals, we further differentiate between built-in and user-defined datatypes. For the former, we also use the lexical form, e.g. \"123\"⌃⌃xsd:int $\\Rightarrow $ 123, while the latter are processed by using the literal value with its representation of the datatype IRI, e.g., \"123\"⌃⌃dt:squareKilometre as 123 square kilometres.\nThe realization $\\rho $ of a triple (s p o) depends mostly on the verbalization of the predicate p. If p can be realized as a noun phrase, then a possessive clause can be used to express the semantics of (s p o), more formally\n$\\rho $(s p o) $\\Rightarrow $ poss($\\rho $(p),$\\rho $(s))$\\,\\wedge \\,$subj(BE,$\\rho $(p))$\\,\\\\ \\wedge \\,$dobj(BE,$\\rho $(o))\nFor example, if $\\rho (\\texttt {p})$ is a relational noun like birth place e.g. in the triple (:Albert_Einstein :birthPlace :Ulm), then the verbalization is Albert Einstein's birth place is Ulm. Note that BE stands for the verb “to be”. In case p's realization is a verb, then the triple can be verbalized as follows:\n$\\rho $(s p o) $\\Rightarrow $ subj($\\rho $(p),$\\rho $(s))$\\,\\wedge \\,$dobj($\\rho $(p),$\\rho $(o))\nFor example, in (:Albert_Einstein :influenced :Nathan_Rosen) $\\rho (\\texttt {p})$ is the verb influenced, thus, the verbalization is Albert Einstein influenced Nathan Rosen.\nThe same procedure of generating a single triple can be applied for the generation of each triple in a set of triples. However, the NL output would contain redundant information and consequently sound very artificial. Thus, the goal is to transform the generated description to sound more natural. To this end, we focus on two types of transformation rules (cf. BIBREF21): ordering and clustering and grouping. In the following, we describe the transformation rules we employ in more detail. Note that clustering and ordering (SECREF18) is applied before grouping (SECREF26).\nWe process the input trees in descending order with respect to the frequency of the variables they contain, starting with the projection variables and only after that turning to other variables. As an example, consider the following triples about two of the most known people in the world:\nThe five triples are verbalized as given in UNKREF20–UNKREF24. Clustering and ordering first take all sentences containing the subject :Albert_Einstein, i.e. UNKREF21 –UNKREF23, which are ordered such that copulative sentences (such as Albert Einstein is a scientist) come before other sentences, and then takes all sentences containing the remaining subject :William_Shakespeare in UNKREF20 and UNKREF24 resulting in a sequence of sentences as in UNKREF25.\nWilliam Shakespeare is a writer.\nAlbert Einstein's birth place is Ulm.\nAlbert Einstein's death place is Princeton.\nAlbert Einstein is a scientist.\nWilliam Shakespeare's death date is 23 April 1616.\nAlbert Einstein is a scientist. Albert Einstein's birth place is Ulm. Albert Einstein's death place is Princeton. William Shakespeare's is a writer. William Shakespeare's death date is 23 April 1616.\ndalianishovy describe grouping as a process “collecting clauses with common elements and then collapsing the common elements”. The common elements are usually subject noun phrases and verb phrases (verbs together with object noun phrases), leading to subject grouping and object grouping. To maximize the grouping effects, we collapse common prefixes and suffixes of sentences, irrespective of whether they are full subject noun phrases or complete verb phrases. In the following we use $X_1,X_2,$...$X_N$ as variables for the root nodes of the input sentences and $Y$ as variable for the root node of the output sentence. Furthermore, we abbreviate a subject $\\texttt {subj}(X_i,s_i)$ as $\\texttt {s}_i$, an object $\\texttt {dobj}(X_i,o_i)$ as $\\texttt {o}_i$, and a verb $\\texttt {root}(\\text{\\em ROOT}_i,v_i)$ as $\\texttt {v}_i$.\nSubject grouping collapses the predicates (i.e. verb and object) of two sentences if their subjects are the same, as specified in UNKREF27 (abbreviations as above).\n$\\rho (\\texttt {s}_1)=\\rho (\\texttt {s}_2)\\wedge \\texttt {cc}(\\texttt {v}_1,\\text{\\em coord})$\n$\\Rightarrow \\texttt {root}(Y,\\texttt {coord}(\\texttt {v}_1,\\texttt {v}_2))\\wedge \\, \\texttt {subj}(\\texttt {v}_1,\\texttt {s}_1)\\wedge \\texttt {dobj}(\\texttt {v}_1,\\texttt {o}_1)\\wedge \\texttt {subj}(\\texttt {v}_2,\\texttt {s}_1)\\wedge \\texttt {dobj}(\\texttt {v}_1,\\texttt {o}_2) $\nAn example are the sentences given in UNKREF28, which share the subject Albert Einstein and thus can be collaped into a single sentence.\nAlbert Einstein is a scientist and Albert Einstein is known for general relativity.\n$\\Rightarrow $ Albert Einstein is a scientist and known for general relativity.\nObject grouping collapses the subjects of two sentences if the realizations of the verbs and objects of the sentences are the same, where the $\\text{\\em coord}\\in \\lbrace \\text{\\sf and},\\text{\\sf or}\\rbrace $ is the coordination combining the input sentences $X_1$ and $X_2$, and $\\texttt {coord}\\in \\lbrace \\texttt {conj},\\texttt {disj}\\rbrace $ is the corresponding coordination combining the subjects.\n$\\rho (\\texttt {o}_1)=\\rho (\\texttt {o}_2)\\wedge \\rho (\\texttt {v}_1)=\\rho (\\texttt {v}_2)\\wedge \\texttt {cc}(\\texttt {v}_1,\\text{\\em coord})$\n$\\Rightarrow \\texttt {root}(Y,\\texttt {PLURAL}(\\texttt {v}_1))\\wedge \\, \\texttt {subj}(\\texttt {v}_1,\\texttt {coord}(\\texttt {s}_1,\\texttt {s}_2))\\wedge \\texttt {dobj}(\\texttt {v}_1,\\texttt {o}_1) $\nFor example, the sentences in UNKREF30 share their verb and object, thus they can be collapsed into a single sentence. Note that to this end the singular auxiliary was needs to be transformed into its plural form were.\nBenjamin Franklin was born in Boston.

The left blocks and the right blocks form two QANets, each of which takes a document and a question as the input and outputs an answer. In QANet, firstly, an embedding encoder obtains word and character embeddings for each word in INLINEFORM0 or INLINEFORM1 and then models the temporal interactions between words and refines word vectors to contextualized word representations. All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention. The intuition here is that convolution components can model local interactions and self-attention components focus on modeling global interactions. The context-query attention layer generates the question-document similarity matrix and computes the question-aware vector representations of the context words. After that, a model encoder layer containing seven encoder blocks captures the interactions among the context words conditioned on the question.

More generally, any edge-weighted undirected graph (not necessarily connected) has a minimum spanning forest, which is a union of the minimum spanning trees for its connected components.\n\nThere are many use cases for minimum spanning trees. One example is a telecommunications company trying to lay cable in a new neighborhood. If it is constrained to bury the cable only along certain paths (e.g. roads), then there would be a graph containing the points (e.g. houses) connected by those paths. Some of the paths might be more expensive, because they are longer, or require the cable to be buried deeper; these paths would be represented by edges with larger weights. Currency is an acceptable unit for edge weight – there is no requirement for edge lengths to obey normal rules of geometry such as the triangle inequality. A spanning tree for that graph would be a subset of those paths that has no cycles but still connects every house; there might be several spanning trees possible. A minimum spanning tree would be one with the lowest total cost, representing the least expensive path for laying the cable.",

        "answer": "Yes, there are significant differences in the linguistic structure of the open and the answered questions.",
        "evidence": "In this section, we identify various linguistic activities on Quora and propose quantifications of the language usage patterns in this Q&A site. In particular, we show that there exists significant differences in the linguistic structure of the open and the answered questions. Note that most of the measures that we define are simple, intuitive and can be easily obtained automatically from the data (without manual intervention). Therefore the framework is practical, inexpensive and highly scalable.\nContent of a question text is important to attract people and make them engage more toward it. The linguistic structure (i.e., the usage of POS tags, the use of Out-of-Vocabulary words, character usage etc.) one adopts are key factors for answerability of questions. We shall discuss the linguistic structure that often represents the writing style of a question asker.\nIn fig 1 (a), we observe that askers of open questions generally use more no. of words compared to answered questions. To understand the nature of words (standard English words or chat-like words frequently used in social media) used in the text, we compare the words with GNU Aspell dictionary to see whether they are present in the dictionary or not. We observe that both open questions and answered questions follow similar distribution (see fig 1 (b)). Part-of-Speech (POS) tags are indicators of grammatical aspects of texts. To observe how the Part-of-Speech tags are distributed in the question texts, we define a diversity metric. We use the standard CMU POS tagger BIBREF8 for identifying the POS tags of the constituent words in the question. We define the POS tag diversity (POSDiv) of a question $q_i$ as follows: $POSDiv(q_i) = -\\sum _{j \\in pos_{set}}p_j\\times \\log (p_j)$ where $p_j$ is the probability of the $j^{th}$ POS in the set of POS tags. Fig 1 (c) shows that the answered questions have lower POS tag diversity compared to open questions. Question texts undergo several edits so that their readability and the engagement toward them are enhanced. It is interesting to identify how far such edits can make the question different from the original version of it. To capture this phenomena, we have adopted ROUGE-LCS recall BIBREF9 from the domain of text summarization. Higher the recall value, lesser are the changes in the question text. From fig 1 (d), we observe that open questions tend to have higher recall compared to the answered ones which suggests that they have not gone through much of text editing thus allowing for almost no scope of readability enhancement.\nPsycholinguistic analysis: \nThe way an individual talks or writes, give us clue to his/her linguistic, emotional, and cognitive states. A question asker's linguistic, emotional, cognitive states are also revealed through the language he/she uses in the question text. In order to capture such psycholinguistic aspects of the asker, we use Linguistic Inquiry and Word Count (LIWC) BIBREF10 that analyzes various emotional, cognitive, and structural components present in individuals' written texts. LIWC takes a text document as input and outputs a score for the input for each of the LIWC categories such as linguistic (part-of-speech of the words, function words etc.) and psychological categories (social, anger, positive emotion, negative emotion, sadness etc.) based on the writing style and psychometric properties of the document. In table 1 , we perform a comparative analysis of the asker's psycholinguistic state while asking an open question and an answered question.\nAskers of open questions use more function words, impersonal pronouns, articles on an average whereas asker of answered questions use more personal pronouns, conjunctions and adverbs to describe their questions. Essentially, open questions lack content words compared to answered questions which, in turn, affects the readability of the question. As far as the psychological aspects are concerned, answered question askers tend to use more social, family, human related words on average compared to an open question asker. The open question askers express more positive emotions whereas the answered question asker tend to express more negative emotions in their texts. Also, answered question askers are more emotionally involved and their questions reveal higher usage of anger, sadness, anxiety related words compared to that of open questions. Open questions, on the other hand, contains more sexual, body, health related words which might be reasons why they do not attract answers.\nIn table 2 , we show a collection of examples of open questions to illustrate that many of the above quantities based on the linguistic activities described in this section naturally correspond to the factors that human judges consider responsible for a question remaining unanswered. This is one of the prime reasons why these quantities qualify as appropriate indicators of answerability.\nIn particular, we show that there exists significant differences in the linguistic structure of the open and the answered questions.",

I have divided these descriptions into two classes: linguistic bias and unwarranted inferences. The former corresponds to the annotators' choice of words when confronted with an image that may or may not match their stereotypical expectancies. The latter corresponds to the tendency of annotators to go beyond what the physical data can tell us, and expand their descriptions based on their past experiences and knowledge of the world. Acknowledging these phenomena is important, because on the one hand it helps us think about what is learnable from the data, and on the other hand it serves as a warning: if we train and evaluate language models on this data, we are effectively teaching them to be biased.\nI have also looked at methods to detect stereotype-driven descriptions, but due to the richness of language it is difficult to find an automated measure.

As I grew older and ended up writing software and creating & implementing architectures for systems, I thought I would never see the day when a Jetsons-like kitchen would be feasible.\nGPT (ChatGPT, etc.) has changed my mind.\n\nContractual Obligations\nAs an architect, you kind of need to think like a lawyer. You define contracts (APIs) between systems or components. You monitor those APIs for abuse or misuse.\n\nI would use Swagger editor to define those contracts, and I would write the APIs to match interactions implied in mock-ups. I would vet the design with the team, I would walk through scenarios to see if the API would fit the use case and would not introduce performance bottlenecks, and I would simulate and automate as much as I could along the journey.\n\nI was very careful to get it right the first time. It was never perfect the first time, of course. So, I also had to consider how the API could evolve while minimizing costs/impact to the rest of the system. The API, once deployed, would become something I would guard, like an honest politician guards the #usconstitution. The team had to be careful with any change that impacted the API.\n\nAPI Mesh... More like API mess!\nAPIs rely on APIs which rely on more APIs and libraries. Once a system gets large enough, that complexity becomes a bottleneck. Small changes can have a huge ripple effect. Some approaches (like federated #GraphQL) help manage this complexity nicely. But it still involves an API under which there can exist a lot of fragility. #Agile or not, developing a complicated web of APIs is complex, requires specialized skills, and is full of unforeseen challenges.\n\nThe Kitchen Conversation, ChatGPT-style\nThe Jetsons' kitchen involves a number of systems, each composed of various parts, sensors, hardware, inputs and outputs. Considering the complexity of interactions between independent systems in a kitchen, the fact that the Jetsons' kitchen components would come from various vendors or manufacturers, traditional API design would not be able to fulfill the vision. Not practical, at all.\n\nNow, let's think about APIs and the Jetsons' kitchen, #chatgpt -style.\n\nLet's keep it simple: pizza. You (or your robot) make a pizza from scratch.\n\nThe oven asks the refrigerator: \"I see we have a pizza. Can you tell me if this is low-moisture mozzarella?\"\n\nRefrigerator: \"That's not even mozzarella. This pizza must have Muenster cheese as that is all I had in me. And the human removed some of the contents 30 minutes ago, so the probability of Muenster cheese on that pizza is quite high.\"\n\nA sensor from the kitchen who has eyes across the room chimes in at this point. Sensor: \"Beware that the crust of this pizza is made of cauliflower. I agree with the video sensor's assessment regarding the type of cheese. No new cheese entered the kitchen recently.\"\n\nOven: \"Anything else I should know?\"\n\nSensor: \"The temperature of the dough is 47F. This is cooler than the expert chef consensus of using room-temperature dough.\"\n\nOven: \"Great. I know what to do. Since the dough is cool, I will start cooking with a temperature a little lower than the recipe specifies. Then I will increase the temp of bottom element so as to provide a nice crisp crust. I will keep a close eye on moisture and may use convection to mitigate any undesirable levels of moisture.\"\n\nWhere is the API that contractually binds the independent systems? APIs are not gone. For instance, the brain of the Oven will have myriad APIs (e.g. for interacting with temperature controllers and sensors, etc.).

        "evidence": "A core step in many analyses is translating social and cultural concepts (such as hate speech, rumor, or conversion) into measurable quantities. Before we can develop measurements for these concepts (the operationalization step, or the “implementation” step as denoted by BIBREF12 ), we need to define them. In the conceptualization phase we often start with questions such as: who are the domain experts, and how have they approached the topic? We are looking for a definition of the concept that is flexible enough to apply on our dataset, yet formal enough for computational research. For example, our introductory study on hate speech BIBREF0 used a statement on hate speech produced by the European Union Court of Human Rights. The goal was not to implement this definition directly in software but to use it as a reference point to anchor subsequent analyses.\nIf we want to move beyond the use of ad hoc definitions, it can be useful to distinguish between what political scientists Adcock and Collier call the “background concept” and the “systematized concept” BIBREF13 . The background concept comprises the full and diverse set of meanings that might be associated with a particular term. This involves delving into theoretical, conceptual, and empirical studies to assess how a concept has been defined by other scholars and, most importantly, to determine which definition is most appropriate for the particular research question and the theoretical framework in which it is situated. That definition, in turn, represents the systematized concept: the formulation that is adopted for the study.\nIt is important to consider that for social and cultural concepts there is no absolute ground truth. There are often multiple valid definitions for a concept (the “background” concept in the terms of Adcock and Collier), and definitions might be contested over time. This may be uncomfortable for computer scientists, whose primary measure of success is often based on comparing a model's output against “ground truth” or a “gold standard”, e.g., by comparing a sentiment classifier's output against manual annotations. However, the notion of ground truth is uncommon in the humanities and the social sciences and it is often taken too far in machine learning. BIBREF14 notes that in literary criticism and the digital humanities more broadly “interpretation, ambiguity, and argumentation are prized far above ground truth and definitive conclusions\". BIBREF15 draw attention to the different attitudes of literary scholars and computational linguists towards ambiguity, stating that “In Computational Linguistics [..] ambiguity is almost uniformly treated as a problem to be solved; the focus is on disambiguation, with the assumption that one true, correct interpretation exists.\" The latter is probably true for tasks such as spam filtering, but in the social sciences and the humanities many relevant concepts are fundamentally unobservable, such as latent traits of political actors BIBREF16 or cultural fit in organizations BIBREF17 , leading to validation challenges. Moreover, when the ground truth comes from people, it may be influenced by ideological priors, priming, simple differences of opinion or perspective, and many other factors BIBREF18 . We return to this issue in our discussions on validation and analysis.\nWe are looking for a definition of the concept that is flexible enough to apply on our dataset, yet formal enough for computational research.",

If a party were allowed to unilaterally change the term of a contract, there may be no value in having a contract in the first place as an obvious change would be to change what a party has promised in the contract to little or nothing at all. This would erode any value of having a contract in the first place. However, there are contracts that allow a party to unilaterally change certain terms of the contract but they should not take away the substantial benefit of the contract from the other party or parties. If a party has agreed to allow the other to vary any of the terms of the contract, this is not ideal and the implications would depend on the extent and nature of the variations made.

        "evidence": "The use of categorical attributes (e.g., user, topic, aspects) in the sentiment analysis community BIBREF0, BIBREF1, BIBREF2 is widespread. Prior to the deep learning era, these information were used as effective categorical features BIBREF3, BIBREF4, BIBREF5, BIBREF6 for the machine learning model. Recent work has used them to improve the overall performance BIBREF7, BIBREF8, interpretability BIBREF9, BIBREF10, and personalization BIBREF11 of neural network models in different tasks such as sentiment classification BIBREF12, review summarization BIBREF13, and text generation BIBREF8.\nIn particular, user and product information have been widely incorporated in sentiment classification models, especially since they are important metadata attributes found in review websites. BIBREF12 first showed significant accuracy increase of neural models when these information are used. Currently, the accepted standard method is to use them as additional biases when computing the weights $a$ in the attention mechanism, as introduced by BIBREF7 as:\nwhere $u$ and $p$ are the user and product embeddings, and $h$ is a word encoding from BiLSTM. Since then, most of the subsequent work attempted to improve the model by extending the model architecture to be able to utilize external features BIBREF14, handle cold-start entities BIBREF9, and represent user and product separately BIBREF15.\nIntuitively, however, this method is not the ideal method to represent and inject attributes because of two reasons. First, representing attributes as additional biases cannot model the relationship between the text and attributes. Rather, it only adds a user- and product-specific biases that are independent from the text when calculating the attention weights. Second, injecting the attributes in the attention mechanism means that user and product information are only used to customize how the model choose which words to focus on, as also shown empirically in previous work BIBREF7, BIBREF15. However, we argue that there are more intuitive locations to inject the attributes such as when contextualizing words to modify their sentiment intensity.\nWe propose to represent user and product information as weight matrices (i.e., $W$ in the equation above). Directly incorporating these attributes into $W$ leads to large increase in parameters and subsequently makes the model difficult to optimize. To mitigate these problems, we introduce chunk-wise importance weight matrices, which (1) uses a weight matrix smaller than $W$ by a chunk size factor, and (2) transforms these matrix into gates such that it corresponds to the relative importance of each neuron in $W$. We investigate the use of this method when injected to several locations in the base model: word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.\nThe results of our experiments can be summarized in three statements. First, our preliminary experiments show that doing bias-based attribute representation and attention-based injection is not an effective method to incorporate user and product information in sentiment classification models. Second, despite using only a simple BiLSTM with attention classifier, we significantly outperform previous state-of-the-art models that use more complicated architectures (e.g., models that use hierarchical models, external memory networks, etc.). Finally, we show that these attribute representations transfer well to other tasks such as product category classification and review headline generation.\nFirst, our preliminary experiments show that doing bias-based attribute representation and attention-based injection is not an effective method to incorporate user and product information in sentiment classification models.",

The problem is stated as follows: Imagine you are a contestant on a game show and the host shows you 3 doors. Behind one of the doors is a car and behind the other two are goats. The prizes have been randomly assigned to the doors and you want to win the car. The host allows you to pick one of the doors as a first selection. Then, the host opens one of the remaining doors and reveals a goat is behind it. The host now allows you to decide if you want to switch from your selected door to the remaining unopened door. Should you switch, to maximize your probability of winning the car?\n\nMost people believe switching does not improve your probability of winning the car. However switching does increase your probability of winning the car from 1/3 to 2/3. An intuitive way to understand this problem is by first considering the initial state. At your first selection the probability that you have selected the right door is 1/3 and the probability that the car remains behind one of the two unselected doors is 2/3. Then the host reveals more information. The host reveals that one of the unselected doors does not have the car behind it. The probability that the originally unselected doors must have the car behind one of them is still 2/3, but you now know one of them specifically which does not have the car. Therefore, the remaining unopened unselected door must have a probability of 2/3 to contain the car, and your originally selected door must have a probability of 1/3.

        "evidence": "The ideological leanings of a person within the left-right political spectrum are often reflected by how one feels about different topics and by means of preferences among various choices on particular issues. For example, a left-leaning person would prefer nationalization and state control of public services (such as healthcare) where privatization would be often preferred by people that lean towards the right. Likewise, a left-leaning person would often be supportive of immigration and will often talk about immigration in a positive manner citing examples of benefits of immigration on a country's economy. A right-leaning person, on the other hand, will often have a negative opinion about immigration.\nMost of the existing works on political ideology detection from text have focused on utilizing bag-of-words and other syntactic features to capture variations in language use BIBREF0 , BIBREF1 , BIBREF2 . We propose an alternative mechanism for political ideology detection based on sentiment analysis. We posit that adherents of a political ideology generally have similar sentiment toward specific topics (for example, right wing followers are often positive towards free markets, lower tax rates, etc.) and thus, a political ideology can be represented by a characteristic sentiment distribution over different topics (Section SECREF3 ). This topic-specific sentiment representation of a political ideology can then be used for automatic ideology detection by comparing the topic-specific sentiments as expressed by the content in a document (news article, magazine article, collection of social media posts by a user, utterances in a conversation, etc.).\nIn order to validate our hypothesis, we consider exploiting the sentiment information towards topics from archives of political debates to build a model for identifying political orientation of speakers as one of right or left leaning, which corresponds to republicans and democrats respectively, within the context of US politics. This is inspired by our observation that the political leanings of debators are often expressed in debates by way of speakers' sentiments towards particular topics. Parliamentary or Senate debates often bring the ideological differences to the centre stage, though somewhat indirectly. Heated debates in such forums tend to focus on the choices proposed by the executive that are in sharp conflict with the preference structure of the opposition members. Due to this inherent tendency of parliamentary debates to focus on topics of disagreement, the sentiments exposited in debates hold valuable cues to identify the political orientation of the participants.\nWe develop a simple classification model that uses a topic-specific sentiment summarization for republican and democrat speeches separately. Initial results of experiments conducted using a widely used dataset of US Congress debates BIBREF3 are encouraging and show that this simple model compares well with classification models that employ state-of-the-art distributional text representations (Section SECREF4 ).\nInitial results of experiments conducted using a widely used dataset of US Congress debates are encouraging and show that this simple model compares well with classification models that employ state-of-the-art distributional text representations (Section SECREF4 ).",

        "evidence": "Until recently, efforts to bring out semantics from structured-data relied heavily on expert knowledge BIBREF22, BIBREF8. For example, in order to better transcribe numerical time series of weather data to a textual forecast, Reiter et al. BIBREF8 devise complex template schemes in collaboration with weather experts to build a consistent set of data-to-word rules.\nModern approaches to the wide range of tasks based on structured-data (e.g. table retrieval BIBREF2, BIBREF23, table classification BIBREF24, question answering BIBREF25) now propose to leverage progress in deep learning to represent these data into a semantic vector space (also called embedding space). In parallel, an emerging task, called “data-to-text\", aims at describing structured data into a natural language description. This task stems from the neural machine translation (NMT) domain, and early work BIBREF26, BIBREF27, BIBREF10 represent the data records as a single sequence of facts to be entirely translated into natural language. Wiseman et al. BIBREF10 show the limits of traditional NMT systems on larger structured-data, where NMT systems fail to accurately extract salient elements.\nTo improve these models, a number of work BIBREF28, BIBREF12, BIBREF29 proposed innovating decoding modules based on planning and templates, to ensure factual and coherent mentions of records in generated descriptions. For example, Puduppully et al. BIBREF12 propose a two-step decoder which first targets specific records and then use them as a plan for the actual text generation. Similarly, Li et al. BIBREF28 proposed a delayed copy mechanism where their decoder also acts in two steps: 1) using a classical LSTM decoder to generate delexicalized text and 2) using a pointer network BIBREF30 to replace placeholders by records from the input data.\nCloser to our work, very recent work BIBREF11, BIBREF19, BIBREF13 have proposed to take into account the data structure. More particularly, Puduppully et al. BIBREF13 follow entity-centric theories BIBREF31, BIBREF32 and propose a model based on dynamic entity representation at decoding time. It consists in conditioning the decoder on entity representations that are updated during inference at each decoding step. On the other hand, Liu et al. BIBREF11, BIBREF19 rather focus on introducing structure into the encoder. For instance, they propose a dual encoder BIBREF19 which encodes separately the sequence of element names and the sequence of element values. These approaches are however designed for single-entity data structures and do not account for delimitation between entities.\nOur contribution differs from previous work in several aspects. First, instead of flatly concatenating elements from the data-structure and encoding them as a sequence BIBREF11, BIBREF12, BIBREF10, we constrain the encoding to the underlying structure of the input data, so that the delimitation between entities remains clear throughout the process. Second, unlike all works in the domain, we exploit the Transformer architecture BIBREF21 and leverage its particularity to directly compare elements with each others in order to avoid arbitrary assumptions on their ordering. Finally, in contrast to BIBREF33, BIBREF13 that use a complex updating mechanism to obtain a dynamic representation of the input data and its entities, we argue that explicit hierarchical encoding naturally guides the decoding process via hierarchical attention.\n\nFirst, instead of flatly concatenating elements from the data-structure and encoding them as a sequence [18,28,39], we constrain the encoding to the underlying structure of the input data, so that the delimitation between entities remains clear throughout the process.",

Large-scaled datasets like SNLI BIBREF0 and MultiNLI BIBREF1 have been created by crowd-sourcing and fertilized NLI research substantially.\nHowever, several works BIBREF2, BIBREF3, BIBREF4 have pointed out that crowd-sourcing workers have brought a bias pattern named annotation artifacts in these NLI datasets. Such artifacts in hypotheses can reveal the labels and make it possible to predict the labels solely by looking at the hypotheses. For example, models trained on SNLI with only the hypotheses can achieve an accuracy of 67.0%, despite the always predicting the majority-class baseline is only 34.3% BIBREF2.\nClassifiers trained on NLI datasets are supposed to make predictions by understanding the semantic relationships between given sentence pairs. However, it is shown that models are unintentionally utilizing the annotation artifacts BIBREF4, BIBREF2. If the evaluation is conducted under a similar distribution as the training data, e.g., with the given testing set, models will enjoy additional advantages, making the evaluation results over-estimated. On the other hand, if the bias pattern cannot be generalized to the real-world, it may introduce noise to models, thus hurting the generalization ability.\nIn this paper, we use cross-dataset testing to better assess models' generalization ability. We investigate the impacts of annotation artifacts in cross-dataset testing. Furthermore, we propose an easy-adopting debiasing training framework, which doesn't require any additional data or annotations, and apply it to the high-performing Densely Interactive Inference Network BIBREF5.

        "question": "Create a list using bullets of the Beatles band members and tell me if they are alive or dead using the format {Name} / {Alive or Dead}",
        "evidence": "The Beatles were an English rock band, formed in Liverpool in 1960, that comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band of all time and were integral to the development of 1960s counterculture and popular music's recognition as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways; the band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionised many aspects of the music industry and were often publicised as leaders of the era's youth and sociocultural movements.\n\nLed by primary songwriters Lennon and McCartney, the Beatles evolved from Lennon's previous group, the Quarrymen, and built their reputation playing clubs in Liverpool and Hamburg over three years from 1960, initially with Stuart Sutcliffe playing bass. The core trio of Lennon, McCartney and Harrison, together since 1958, went through a succession of drummers, including Pete Best, before asking Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act, and producer George Martin guided and developed their recordings, greatly expanding their domestic success after signing to EMI Records and achieving their first hit, \"Love Me Do\", in late 1962. As their popularity grew into the intense fan frenzy dubbed \"Beatlemania\", the band acquired the nickname \"the Fab Four\", with Epstein, Martin or another member of the band's entourage sometimes informally referred to as a \"fifth Beatle\".\n\nBy early 1964, the Beatles were international stars and had achieved unprecedented levels of critical and commercial success. They became a leading force in Britain's cultural resurgence, ushering in the British Invasion of the United States pop market, and soon made their film debut with A Hard Day's Night (1964). A growing desire to refine their studio efforts, coupled with the untenable nature of their concert tours, led to the band's retirement from live performances in 1966. At this time, they produced records of greater sophistication, including the albums Rubber Soul (1965), Revolver (1966) and Sgt. Pepper's Lonely Hearts Club Band (1967), and enjoyed further commercial success with The Beatles (also known as \"the White Album\", 1968) and Abbey Road (1969). The success of these records heralded the album era, as albums became the dominant form of record consumption over singles; they also increased public interest in psychedelic drugs and Eastern spirituality, and furthered advancements in electronic music, album art and music videos. In 1968, they founded Apple Corps, a multi-armed multimedia corporation that continues to oversee projects related to the band's legacy. After the group's break-up in 1970, all principal former members enjoyed success as solo artists and some partial reunions have occurred. Lennon was murdered in 1980 and Harrison died of lung cancer in 2001. McCartney and Starr remain musically active.\n\nThe Beatles are the best-selling music act of all time, with estimated sales of 600 million units worldwide. They are the most successful act in the history of the US Billboard charts. They hold the record for most number-one albums on the UK Albums Chart (15), most number-one hits on the US Billboard Hot 100 chart (20), and most singles sold in the UK (21.9 million). The band received many accolades, including seven Grammy Awards, four Brit Awards, an Academy Award (for Best Original Song Score for the 1970 documentary film Let It Be) and fifteen Ivor Novello Awards. They were inducted into the Rock and Roll Hall of Fame in 1988, and each principal member was inducted individually between 1994 and 2015. In 2004 and 2011, the group topped Rolling Stone's lists of the greatest artists in history. Time magazine named them among the 20th century's 100 most important people.",

        "evidence": "We created a new dataset called CW-USPD-2016 (check-worthiness in the US presidential debates 2016) for finding check-worthy claims in context. In particular, we used four transcripts of the 2016 US election: one vice-presidential and three presidential debates. For each debate, we used the publicly-available manual analysis about it from nine reputable fact-checking sources, as shown in Table TABREF7. This could include not just a statement about factuality, but any free text that journalists decided to add, e.g., links to biographies or behavioral analysis of the opponents and moderators. We converted this to binary annotation about whether a particular sentence was annotated for factuality by a given source. Whenever one or more annotations were about part of a sentence, we selected the entire sentence, and when an annotation spanned over multiple sentences, we selected each of them.\nUltimately, we ended up with a dataset of four debates, with a total of 5,415 sentences. The agreement between the sources was low as Table TABREF8 shows: only one sentence was selected by all nine sources, 57 sentences by at least five, 197 by at least three, 388 by at least two, and 880 by at least one. The reason for this is that the different media aimed at annotating sentences according to their own editorial line, rather than trying to be exhaustive in any way. This suggests that the task of predicting which sentence would contain check-worthy claims will be challenging. Thus, below we focus on a ranking task rather than on absolute predictions. Moreover, we predict which sentence would be selected (i) by at least one of the media, or (ii) by a specific medium.\nNote that the investigative journalists did not select the check-worthy claims in isolation. Our analysis shows that these include claims that were highly disputed during the debate, that were relevant to the topic introduced by the moderator, etc. We will make use of these contextual dependencies below, which is something that was not previously tried in related work.\nIn particular, we used four transcripts of the 2016 US election: one vice-presidential and three presidential debates.",

        "question": "What insight is their approach based on?",
        "answer": "Messages (whether in neuralese or natural language) have similar meanings when they induce similar beliefs about the state of the world.",
        "evidence": "Several recent papers have described approaches for learning deep communicating policies (DCPs): decentralized representations of behavior that enable multiple agents to communicate via a differentiable channel that can be formulated as a recurrent neural network. DCPs have been shown to solve a variety of coordination problems, including reference games BIBREF0 , logic puzzles BIBREF1 , and simple control BIBREF2 . Appealingly, the agents' communication protocol can be learned via direct backpropagation through the communication channel, avoiding many of the challenging inference problems associated with learning in classical decentralized decision processes BIBREF3 .\nBut analysis of the strategies induced by DCPs has remained a challenge. As an example, fig:teaser depicts a driving game in which two cars, which are unable to see each other, must both cross an intersection without colliding. In order to ensure success, it is clear that the cars must communicate with each other. But a number of successful communication strategies are possible—for example, they might report their exact $(x, y)$ coordinates at every timestep, or they might simply announce whenever they are entering and leaving the intersection. If these messages were communicated in natural language, it would be straightforward to determine which strategy was being employed. However, DCP agents instead communicate with an automatically induced protocol of unstructured, real-valued recurrent state vectors—an artificial language we might call “neuralese,” which superficially bears little resemblance to natural language, and thus frustrates attempts at direct interpretation.\nWe propose to understand neuralese messages by translating them. In this work, we present a simple technique for inducing a dictionary that maps between neuralese message vectors and short natural language strings, given only examples of DCP agents interacting with other agents, and humans interacting with other humans. Natural language already provides a rich set of tools for describing beliefs, observations, and plans—our thesis is that these tools provide a useful complement to the visualization and ablation techniques used in previous work on understanding complex models BIBREF4 , BIBREF5 .\nWhile structurally quite similar to the task of machine translation between pairs of human languages, interpretation of neuralese poses a number of novel challenges. First, there is no natural source of parallel data: there are no bilingual “speakers” of both neuralese and natural language. Second, there may not be a direct correspondence between the strategy employed by humans and DCP agents: even if it were constrained to communicate using natural language, an automated agent might choose to produce a different message from humans in a given state. We tackle both of these challenges by appealing to the grounding of messages in gameplay. Our approach is based on one of the core insights in natural language semantics: messages (whether in neuralese or natural language) have similar meanings when they induce similar beliefs about the state of the world.\nBased on this intuition, we introduce a translation criterion that matches neuralese messages with natural language strings by minimizing statistical distance in a common representation space of distributions over speaker states. We explore several related questions:\nOur translation model and analysis are general, and in fact apply equally to human–computer and human–human translation problems grounded in gameplay. In this paper, we focus our experiments specifically on the problem of interpreting communication in deep policies, and apply our approach to the driving game in fig:teaser and two reference games of the kind shown in fig:bird-examples. We find that this approach outperforms a more conventional machine translation criterion both when attempting to interoperate with neuralese speakers and when predicting their state.\nOur approach is based on one of the core insights in natural language semantics: messages (whether in neuralese or natural language) have similar meanings when they induce similar beliefs about the state of the world.",

        "answer": "The authors use capsules to model the entries at the same dimension in the entity and relation embeddings.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nDifferent from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings.",

        "evidence": "The standard approach to multilingual NLP is to design a single architecture, but tune and train a separate model for each language. While this method allows for customizing the model to the particulars of each language and the available data, it also presents a problem when little data is available: extensive language-specific annotation is required. The reality is that most languages have very little annotated data for most NLP tasks.\nammar2016malopa found that using training data from multiple languages annotated with Universal Dependencies BIBREF1 , and represented using multilingual word vectors, outperformed monolingual training. Inspired by this, we apply the idea of training one model on multiple languages—which we call polyglot training—to PropBank-style semantic role labeling (SRL). We train several parsers for each language in the CoNLL 2009 dataset BIBREF0 : a traditional monolingual version, and variants which additionally incorporate supervision from English portion of the dataset. To our knowledge, this is the first multilingual SRL approach to combine supervision from several languages.\nThe CoNLL 2009 dataset includes seven different languages, allowing study of trends across the same. Unlike the Universal Dependencies dataset, however, the semantic label spaces are entirely language-specific, making our task more challenging. Nonetheless, the success of polyglot training in this setting demonstrates that sharing of statistical strength across languages does not depend on explicit alignment in annotation conventions, and can be done simply through parameter sharing. We show that polyglot training can result in better labeling accuracy than a monolingual parser, especially for low-resource languages. We find that even a simple combination of data is as effective as more complex kinds of polyglot training. We include a breakdown into label categories of the differences between the monolingual and polyglot models. Our findings indicate that polyglot training consistently improves label accuracy for common labels.\nWe train several parsers for each language in the CoNLL 2009 dataset: a traditional monolingual version, and variants which additionally incorporate supervision from English portion of the dataset.",

For instance, consider the example:\nIt might rain tomorrow.\nThe speculation cue in the sentence above is ‘might’ and the scope of the cue ‘might’ is ‘rain tomorrow’. Thus, the speculation cue is the word that expresses the speculation, while the words affected by the speculation are in the scope of that cue.\nThis task was the CoNLL-2010 Shared Task (BIBREF0), which had 3 different subtasks. Task 1B was speculation cue detection on the BioScope Corpus, Task 1W was weasel identification from Wikipedia articles, and Task 2 was speculation scope resolution from the BioScope Corpus. For each task, the participants were provided the train and test set, which is henceforth referred to as Task 1B CoNLL and Task 2 CoNLL throughout this paper.\nFor our experimentation, we use the sub corpora of the BioScope Corpus (BIBREF1), namely the BioScope Abstracts sub corpora, which is referred to as BA, and the BioScope Full Papers sub corpora, which is referred to as BF. We also use the SFU Review Corpus (BIBREF2), which is referred to as SFU.\nThis subtask of natural language processing, along with another similar subtask, negation detection and scope resolution, have been the subject of a body of work over the years. The approaches used to solve them have evolved from simple rule-based systems (BIBREF3) based on linguistic information extracted from the sentences, to modern deep-learning based methods. The Machine Learning techniques used varied from Maximum Entropy Classifiers (BIBREF4) to Support Vector Machines (BIBREF5,BIBREF6,BIBREF7,BIBREF8), while the deep learning approaches included Recursive Neural Networks (BIBREF9,BIBREF10), Convolutional Neural Networks (BIBREF11) and most recently transfer learning-based architectures like Bidirectional Encoder Representation from Transformers (BERT) (BIBREF12). Figures FIGREF1 and FIGREF1 contain a summary of the papers addressing speculation detection and scope resolution (BIBREF13, BIBREF5, BIBREF9, BIBREF3, BIBREF14, BIBREF15, BIBREF16, BIBREF17, BIBREF6, BIBREF11, BIBREF18, BIBREF10, BIBREF19, BIBREF7, BIBREF4, BIBREF8).\nInspired by the most recent approach of applying BERT to negation detection and scope resolution (BIBREF12), we take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT (BIBREF20), XLNet (BIBREF21) and RoBERTa (BIBREF22), applied to speculation detection and scope resolution. We evaluate the performance of each model across all datasets via the single dataset training approach, and report all scores including inter-dataset scores (i.e. train on one dataset, evaluate on another) to test the generalizability of the models. This approach outperforms all existing systems on the task of speculation detection and scope resolution. Further, we jointly train on multiple datasets and obtain improvements over the single dataset training approach on most datasets.\nContrary to results observed on benchmark GLUE tasks, we observe XLNet consistently outperforming RoBERTa. To confirm this observation, we apply these models to the negation detection and scope resolution task, and observe a continuity in this trend, reporting state-of-the-art results on three of four datasets on the negation scope resolution task.\nThe rest of the paper is organized as follows: In Section 2, we provide a detailed description of our methodology and elaborate on the experimentation details. In Section 3, we present our results and analysis on the speculation detection and scope resolution task, using the single dataset and the multiple dataset training approach. In Section 4, we show the results of applying XLNet and RoBERTa on negation detection and scope resolution and propose a few reasons to explain why XLNet performs better than RoBERTa. Finally, the future scope and conclusion is mentioned in Section 5.\nwe take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT, XLNet and RoBERTa, applied to speculation detection and scope resolution.",

In the inference process, the predicted language IDs are used to adjust the output posteriors.

        "question": "What is the characteristic of the word recognition model?",
        "answer": "Predicing each word in a sentence given a full sequence of (possibly misspelled) inputs.",
        "evidence": "Despite the rapid progress of deep learning techniques on diverse supervised learning tasks, these models remain brittle to subtle shifts in the data distribution. Even when the permissible changes are confined to barely-perceptible perturbations, training robust models remains an open challenge. Following the discovery that imperceptible attacks could cause image recognition models to misclassify examples BIBREF0 , a veritable sub-field has emerged in which authors iteratively propose attacks and countermeasures.\nFor all the interest in adversarial computer vision, these attacks are rarely encountered outside of academic research. However, adversarial misspellings constitute a longstanding real-world problem. Spammers continually bombard email servers, subtly misspelling words in efforts to evade spam detection while preserving the emails' intended meaning BIBREF1 , BIBREF2 . As another example, programmatic censorship on the Internet has spurred communities to adopt similar methods to communicate surreptitiously BIBREF3 .\nIn this paper, we focus on adversarially-chosen spelling mistakes in the context of text classification, addressing the following attack types: dropping, adding, and swapping internal characters within words. These perturbations are inspired by psycholinguistic studies BIBREF4 , BIBREF5 which demonstrated that humans can comprehend text altered by jumbling internal characters, provided that the first and last characters of each word remain unperturbed.\nFirst, in experiments addressing both BiLSTM and fine-tuned BERT models, comprising four different input formats: word-only, char-only, word+char, and word-piece BIBREF6 , we demonstrate that an adversary can degrade a classifier's performance to that achieved by random guessing. This requires altering just two characters per sentence. Such modifications might flip words either to a different word in the vocabulary or, more often, to the out-of-vocabulary token UNK. Consequently, adversarial edits can degrade a word-level model by transforming the informative words to UNK. Intuitively, one might suspect that word-piece and character-level models would be less susceptible to spelling attacks as they can make use of the residual word context. However, our experiments demonstrate that character and word-piece models are in fact more vulnerable. We show that this is due to the adversary's effective capacity for finer grained manipulations on these models. While against a word-level model, the adversary is mostly limited to UNK-ing words, against a word-piece or character-level model, each character-level add, drop, or swap produces a distinct input, providing the adversary with a greater set of options.\nSecond, we evaluate first-line techniques including data augmentation and adversarial training, demonstrating that they offer only marginal benefits here, e.g., a BERT model achieving $90.3$ accuracy on a sentiment classification task, is degraded to $64.1$ by an adversarially-chosen 1-character swap in the sentence, which can only be restored to $69.2$ by adversarial training.\nThird (our primary contribution), we propose a task-agnostic defense, attaching a word recognition model that predicts each word in a sentence given a full sequence of (possibly misspelled) inputs. The word recognition model's outputs form the input to a downstream classification model. Our word recognition models build upon the RNN-based semi-character word recognition model due to BIBREF7 . While our word recognizers are trained on domain-specific text from the task at hand, they often predict UNK at test time, owing to the small domain-specific vocabulary. To handle unobserved and rare words, we propose several backoff strategies including falling back on a generic word recognizer trained on a larger corpus. Incorporating our defenses, BERT models subject to 1-character attacks are restored to $88.3$ , $81.1$ , $78.0$ accuracy for swap, drop, add attacks respectively, as compared to $69.2$ , $63.6$ , and $50.0$ for adversarial training\nFourth, we offer a detailed qualitative analysis, demonstrating that a low word error rate alone is insufficient for a word recognizer to confer robustness on the downstream task. Additionally, we find that it is important that the recognition model supply few degrees of freedom to an attacker. We provide a metric to quantify this notion of sensitivity in word recognition models and study its relation to robustness empirically. Models with low sensitivity and word error rate are most robust.\nThird (our primary contribution), we propose a task-agnostic defense, attaching a word recognition model that predicts each word in a sentence given a full sequence of (possibly misspelled) inputs.",

        "evidence": "Clinical text structuring (CTS) is a critical task for fetching medical research data from electronic health records (EHRs), where structural patient medical data, such as whether the patient has specific symptoms, diseases, or what the tumor size is, how far from the tumor is cut at during the surgery, or what the specific laboratory test result is, are obtained. It is important to extract structured data from clinical text because bio-medical systems or bio-medical researches greatly rely on structured data but they cannot obtain them directly. In addition, clinical text often contains abundant healthcare information. CTS is able to provide large-scale extracted structured data for enormous down-stream clinical researches.\nHowever, end-to-end CTS is a very challenging task. Different CTS tasks often have non-uniform output formats, such as specific-class classifications (e.g. tumor stage), strings in the original text (e.g. result for a laboratory test) and inferred values from part of the original text (e.g. calculated tumor size). Researchers have to construct different models for it, which is already costly, and hence it calls for a lot of labeled data for each model. Moreover, labeling necessary amount of data for training neural network requires expensive labor cost. To handle it, researchers turn to some rule-based structuring methods which often have lower labor cost.\nTo reduce the pipeline depth and break the barrier of non-uniform output formats, we present a question answering based clinical text structuring (QA-CTS) task (see Fig. FIGREF1). Unlike the traditional CTS task, our QA-CTS task aims to discover the most related text from original paragraph text. For some cases, it is already the final answer in deed (e.g., extracting sub-string). While for other cases, it needs several steps to obtain the final answer, such as entity names conversion and negative words recognition. Our presented QA-CTS task unifies the output format of the traditional CTS task and make the training data shareable, thus enriching the training data.

        "answer": "Congratulations on your growing family! Pets are often treated like another member of the family and while they can require a lot of work, they can also bring a lot of joy and laughter into your life.\n\nHere are a few options for pets and some advantages and disadvantages for each:\n\n1. Dogs - Dogs can be amazing pets. They are typically very loyal, friendly, and beloved by families all over the world. Dogs can be taught to do tricks like sit, stay, and fetch. There are also over 300 different breeds of dog and they come in all kinds of sizes, ranging from a few lbs (1-2 kg) to over 150 lbs (70 kg). Dogs require quite a bit of work to train and can be very expensive to own due to high veterinary bills. Some dogs can be aggressive, and this is an important factor to consider given that you have two young children. Dogs also typically require access to a yard or regular walking to ensure that they are not going to the bathroom inside. Also, many people are allergic to dogs due to the fact that most dogs shed. If your family members are prone to allergies and are still looking to add a dog to the family, perhaps you should consider a hypoallergenic breed like a Yorkshire Terrier, poodle, or a poodle mix like a Golden Doodle. Dogs typically live between 7-15 years, depending on the breed. \n\n2. Cats - Cats are another very popular pet option for families. Like dogs, they come in many different breed options but there are far fewer breed options for cats than dogs. Most cats grow to be about 10 lbs (4 kg), but they can range in size from around 5 lbs (2 kg) to 25 lbs (11 kg). Indoor cats typically live between 12-18 years. Cats typically require far less work and are generally more independent than dogs. While most cats can't be trained to do tricks, cats are often lower maintenance than dogs. Cats can often be left alone at the house for a long time. Most cats use a litter box to relieve themselves so they typically don't need regular walks or access to a yard. Like dogs, most cats shed, so allergies and cleaning pet dander can be a nuisance. Cats typically eat less than dogs and often are less expensive to own.\n\n3. Fish - Fish are a popular pet option for families that are looking for a very low maintenance pet that only requires feeding a couple of times per day. Fish typically require water, a clean fish tank and fish food, and that's about it. Some pet fish, like goldfish, can be bought for as little as $10, while exotic fish can cost hundreds or even thousands of dollars. Most pet fish will live up to 2 years if properly cared for, but certain species can live up to 30 years. \n\n4. Reptiles - Reptiles like snakes, lizards, or iguanas can also be pets. They typically require low maintenance and can live for up to 20-30 years. They require a cage, regular feeding, and are generally easy to take care of. For medical emergencies, they may require specialized veterinarians or doctor's, which can be hard to find.\n\n5. Rodents - rodents like gerbils, hamsters and even mice can be pets as well. They require regular feeding and a small cage, and are typically very easy to take care of. People often include a running wheel in the cage for these small animals so that they can exercise. However, they don't live very long; most rodents only live for a couple of years at most. \n\nIn addition to the list above, there are many other options for pets such as guinea pigs, rabbits, pigs and even exotic options like monkeys. Depending on where you live, there may be certain restrictions on the types of pets that you can own. Please be sure to check with these restrictions before buying your family pet.",

        "evidence": "UTF8gkai With the widespread of electronic health records (EHRs) in recent years, a large number of EHRs can be integrated and shared in different medical environments, which further support the clinical decision making and government health policy formulationBIBREF0. However, most of the information in current medical records is stored in natural language texts, which makes data mining algorithms unable to process these data directly. To extract relational entity triples from the text, researchers generally use entity and relation extraction algorithm, and rely on the central word to convert the triples into key-value pairs, which can be processed by conventional data mining algorithms directly. Fig. FIGREF1 shows an example of entity and relation extraction in the text of EHRs. The text contains three relational entity triples, i.e., $<$咳嗽, 程度等级, 反复$>$ ($<$cough, degree, repeated$>$), $<$咳痰, 程度等, 反复$>$ ($<$expectoration, degree, repeated$>$) and $<$发热, 存在情况, 无$>$ ($<$fever, presence, nonexistent$>$). By using the symptom as the central word, these triples can then be converted into three key-value pairs, i.e., $<$咳嗽的程度等级, 反复$>$ ($<$degree of cough, repeated$>$), $<$咳痰的程度等级, 反复$>$ ($<$degree of expectoration, repeated$>$) and $<$发热的存在情况, 无$>$ ($<$presence of fever, nonexistent$>$).\nUTF8gkai To solve the task of entity and relation extraction, researchers usually follows pipeline processing and split the task into two sub-tasks, namely named entity recognition (NER)BIBREF1 and relation classification (RC)BIBREF2, respectively.\nHowever, this pipeline method usually fails to capture joint features between entity and relationship types. For example, for a valid relation “存在情况(presence)” in Fig. FIGREF1, the types of its two relational entities must be “疾病(disease)”, “症状(symptom)” or “存在词(presence word)”. To capture these joint features, a large number of joint learning models have been proposed BIBREF3, BIBREF4, among which bidirectional long short term memory (Bi-LSTM) BIBREF5, BIBREF6 are commonly used as the shared parameter layer. However, compared with the language models that benefit from abundant knowledge from pre-training and strong feature extraction capability, Bi-LSTM model has relatively lower generalization performance.\nTo improve the performance, a simple solution is to incorporate language model into joint learning as a shared parameter layer. However, the existing models only introduce language models into the NER or RC task separately BIBREF7, BIBREF8. Therefore, the joint features between entity and relationship types still can not be captured. Meanwhile, BIBREF9 considered the joint features, but it also uses Bi-LSTM as the shared parameter layer, resulting the same problem as discussed previously.\nGiven the aforementioned challenges and current researches, we propose a focused attention model based on widely known BERT language model BIBREF10 to jointly for NER and RC tasks. Specifically, through the dynamic range attention mechanism, we construct task-specific MASK matrix to control the attention range of the last $K$ layers in BERT language model, leading to the model focusing on the words of the task. This process helps obtain the corresponding task-specific context-dependent representations. In this way, the modified BERT language model can be used as the shared parameter layer in joint learning NER and RC task. We call the modified BERT language model shared task representation encoder (STR-encoder) in the following paper.\nTo sum up, the main contributions of our work are summarized as follows:\nWe propose a focused attention model to jointly learn NER and RC task. The model integrates BERT language model as a shared parameter layer to achieve better generalization performance.\nIn the proposed model, we incorporate a novel structure, called STR-encoder, which changes the attention range of the last $K$ layers in BERT language model to obtain task-specific context-dependent representations. It can make full use of the original structure of BERT to produce the vector of the task, and can directly use the prior knowledge contained in the pre-trained language model.\nFor RC task, we proposed two different MASK matrices to extract the required feature representation of RC task. The performances of these two matrices are analyzed and compared in the experiment.\nThe rest of the paper is organized as follows. We briefly review the related work on NER, RC and joint entity and relation extraction in Section SECREF2. In Section SECREF3, we present the proposed focused attention model. We report the experimental results in Section SECREF4. Section SECREF5 is dedicated to studying several key factors that affect the performance of our model. Finally, conclusion and future work are given in Section SECREF6.\nIn the proposed model, we incorporate a novel structure, called STR-encoder, which changes the attention range of the last $K$ layers in BERT language model to obtain task-specific context-dependent representations.

        "answer": "We have added more introduction to the rationale behind the proposed streaming data in the introduction. We would like to clarify that we have two main considerations behind the proposed four types of streaming data.\nThe main consideration is to mimic common practical data collection scenarios where streaming data may include different levels of data distribution shift. To this end, we proposed four types of streaming data targeting for four degrees of commonly-seen distribution shift in realistic scenarios.\nThe second consideration is for the ease of a comprehensive empirical study on pre-training with streaming data. For the first time to provide such a systematic study, we believe using streaming data with various degrees of distribution shifts is beneficial for the community to have a comprehensive understanding of the sequential pre-training problem. Streaming data with other complex distribution shifts may be feasible, e.g., mixing different distribution shifts within one streaming data sequence may be more realistic. We call for more attention on pre-training with streaming data and further extending the types of considered data sequence wherein. But for our work, a study on streaming data containing mixed distribution shifts is not easy to probe into the properties of the studied problem. Therefore, we adopt the design of the four scenarios in our paper.",
        "evidence": "Recent advances in self-supervised learning (SSL) demonstrate competitive or even better transfer learning performance on various downstream tasks, compared with supervised pre-training. Although waiving the cost of human labeling, SSL usually requires massive unlabeled data to learn a powerful representation model and benefits from significantly large-scale pre-training data, e.g., adopted billion-scale data to pre-train better SSL models. The common pre-training practice follows the joint training (JT) setup, where massive unlabeled data are collected together before model training. In reality, however, it is usually difficult to access a large amount of collective unlabeled data at once. Instead, real-world data are usually accessed in a streaming fashion, e.g., data are generated and collected sequentially chunk by chunk, or even decentralized and stored in different servers; such a learning setup is known as sequential training (ST). Despite much research effort and promising results achieved by JT, it inevitably suffers from heavy data storage, prolonged training time, and finds itself incompetent when training data volume expands over time. For ST, on the other hand, a learner can be sequentially trained with disjoint data chunks, making it much more efficient than JT.\nHow to effectively and efficiently pre-train a representation model under the ST setup has been an open problem. Despite the high efficiency, some continual learning research works have shown that ST with supervised models tends to suffer from catastrophic forgetting, having a significant performance degradation on the historical data chunks. Unlike the case of continual learning tasks, in pre-training tasks, one expects the model to well generalize to downstream tasks rather than focusing only on the seen tasks. Nevertheless, how well sequential self-supervised models perform on downstream tasks remains unclear. to measure the semantic similarity of classes. Classes having the same parent or ancestor in WordNet, marked with similar colors, share similar semantics in the class semantic tree.\nTo fill the research gap, we provide a thorough empirical study on self-supervised pre-training with streaming data. In the pre-training stage, to mimic real-world data collection scenarios and for the better dissection of sequential SSL, we consider streaming data with different degrees of distribution shifts. As shown in Figure, we obtain four types of streaming data, including the instance incremental sequence with negligible data distribution shifts, by randomly splitting ImageNet-1K into four independent and identically distributed (IID) data chunks, the random class incremental sequence with moderate data distribution shifts, by randomly splitting 1K classes of images into four disjoint chunks each with 250 classes, the distant class incremental sequence with severe data distribution shifts, by splitting 1K classes of data into four chunks while maximizing the semantical dissimilarity among chunks, and the domain incremental sequence with severe domain distribution shifts, by taking each domain in DomainNet as a data chunk.\nAs for the evaluation, we consider three downstream tasks following, including few-shot evaluation and linear evaluation (also named many-shot classification) on 12 image classification datasets, and the Pascal VOC detection task. Through extensive experiments with more than 500 pre-trained models, we thoroughly investigate key roles in sequential SSL, including streaming data, downstream tasks and datasets, continual learning methods, SSL methods, and the method efficiency in terms of time and storage. We also thoroughly investigate the knowledge forgetting behavior of sequential SSL and supervised learning (SL) models and provide a comprehensive empirical analysis of the underlying reason.\nTo the best of our knowledge, we are among the first to explore the sequential self-supervised pretraining setting and the first to provide a thorough empirical study on self-supervised pre-training with streaming data. We summarize the takeaways as well as our contributions as: i). Sequential SSL models exhibit the on-par transfer learning performance as joint SSL models on streaming data with negligible or mild distribution shifts. As for streaming data with severe distribution shifts or longer sequences, i.e., the distant class incremental sequence, evident performance gaps exist between sequential SSL and joint SSL models. Such performance gaps, however, can be mitigated effectively and efficiently with unsupervised parameter regularization and simple data replay. ii). Based on the above finding, we conclude that the standard joint training paradigm may be unnecessary for SSL pre-training. Instead, sequential SSL is performance-competitive but more time-efficient and storage-saving and is well worth considering as the practical practice for selfsupervised pre-training with streaming data. iii). Compared with supervised learning (SL) models, SSL models consistently show smaller performance gaps between ST and JT. Our comprehensive investigation of learned representations demonstrates that sequential SSL models are less prone to catastrophic forgetting than SL models. iv). Through the empirical analysis on the sharpness of minima in the loss landscape, we find that SSL models have wider minima than SL models, which we hypothesize is the reason for less forgetting of SSL models.\nIn the pre-training stage, to mimic real-world data collection scenarios and for the better dissection of sequential SSL, we consider streaming data with different degrees of distribution shifts. As shown in Figure 1, we obtain four types of streaming data, including the instance incremental sequence with negligible data distribution shifts, by randomly splitting ImageNet-1K (Russakovsky et al., 2015) into four independent and identically distributed (IID) data chunks, the random class incremental sequence with moderate data distribution shifts, by randomly splitting 1K classes of images into four disjoint chunks each with 250 classes, the distant class incremental sequence with severe data distribution shifts, by splitting 1K classes of data into four chunks while maximizing the semantical dissimilarity among chunks, and the domain incremental sequence with severe domain distribution shifts, by taking each domain in DomainNet (Peng et al., 2019) as a data chunk.",

        "question": "Why is big data not appropriate for this task?",
        "answer": "Training embeddings from small-corpora can increase the performance of some tasks",
        "evidence": "Word embeddings have risen in popularity for NLP applications due to the success of models designed specifically for the big data setting. In particular, BIBREF0 , BIBREF1 showed that very simple word embedding models with high-dimensional representations can scale up to massive datasets, allowing them to outperform more sophisticated neural network language models which can process fewer documents. In this work, I offer a somewhat contrarian perspective to the currently prevailing trend of big data optimism, as exemplified by the work of BIBREF0 , BIBREF1 , BIBREF3 , and others, who argue that massive datasets are sufficient to allow language models to automatically resolve many challenging NLP tasks. Note that “big” datasets are not always available, particularly in computational social science NLP applications, where the data of interest are often not obtained from large scale sources such as the internet and social media, but from sources such as press releases BIBREF11 , academic journals BIBREF10 , books BIBREF12 , and transcripts of recorded speech BIBREF13 , BIBREF14 , BIBREF15 . A standard practice in the literature is to train word embedding models on a generic large corpus such as Wikipedia, and use the embeddings for NLP tasks on the target dataset, cf. BIBREF3 , BIBREF0 , BIBREF16 , BIBREF17 . However, as we shall see here, this standard practice might not always be effective, as the size of a dataset does not correspond to its degree of relevance for a particular analysis. Even very large corpora have idiosyncrasies that can make their embeddings invalid for other domains. For instance, suppose we would like to use word embeddings to analyze scientific articles on machine learning. In Table TABREF1 , I report the most similar words to the word “learning” based on word embedding models trained on two corpora. For embeddings trained on articles from the NIPS conference, the most similar words are related to machine learning, as desired, while for embeddings trained on the massive, generic Google News corpus, the most similar words relate to learning and teaching in the classroom. Evidently, domain-specific data can be important.\nI have proposed a model-based method for training interpretable corpus-specific word embeddings for computational social science, using mixed membership representations, Metropolis-Hastings-Walker sampling, and NCE. Experimental results for prediction, supervised learning, and case studies on state of the Union addresses and NIPS articles, indicate that high-quality embeddings and topics can be obtained using the method. The results highlight the fact that big data is not always best, as domain-specific data can be very valuable, even when it is small.

He made his first firearm at age 13 in his father's gun shop and was awarded the first of his 128 firearm patents on October 7, 1879, at the age of 24. He is regarded as one of the most successful firearms designers of the 19th and 20th centuries and pioneered the development of modern repeating, semi-automatic, and automatic firearms.\n\nBrowning influenced nearly all categories of firearms design, especially the autoloading of ammunition. He invented, or made significant improvements to, single-shot, lever-action, and pump-action rifles and shotguns. He developed the first reliable and compact autoloading pistols by inventing the telescoping bolt, then integrating the bolt and barrel shroud into what is known as the pistol slide. Browning's telescoping bolt design is now found on nearly every modern semi-automatic pistol, as well as several modern fully automatic weapons. He also developed the first gas-operated firearm, the Colt–Browning Model 1895 machine gun – a system that surpassed mechanical recoil operation to become the standard for most high-power self-loading firearm designs worldwide. He also made significant contributions to automatic cannon development.\n\nBrowning's most successful designs include the M1911 pistol, the water-cooled M1917, the air-cooled M1919, and heavy M2 machine guns, the M1918 Browning Automatic Rifle, and the Browning Auto-5 – the first semi-automatic shotgun. Some of these arms are still manufactured, often with only minor changes in detail and cosmetics to those assembled by Browning or his licensees. The Browning-designed M1911 and Hi-Power are some of the most copied firearms in the world.",

        "answer": "In business theory, disruptive innovation is innovation that creates a new market and value network or enters at the bottom of an existing market and eventually displaces established market-leading firms, products, and alliances. The concept was developed by the American academic Clayton Christensen and his collaborators beginning in 1995,[full citation needed] and has been called the most influential business idea of the early 21st century. Lingfei Wu, Dashun Wang, and James A. Evans generalized this term to identify disruptive science and technological advances from more than 65 million papers, patents and software products that span the period 1954–2014. Their work was featured as the cover of the February 2019 issue of Nature  and was included among the Altmetric 100 most-discussed work in 2019.\n\nNot all innovations are disruptive, even if they are revolutionary. For example, the first automobiles in the late 19th century were not a disruptive innovation, because early automobiles were expensive luxury items that did not disrupt the market for horse-drawn vehicles. The market for transportation essentially remained intact until the debut of the lower-priced Ford Model T in 1908. The mass-produced automobile was a disruptive innovation, because it changed the transportation market, whereas the first thirty years of automobiles did not.\n\nDisruptive innovations tend to be produced by outsiders and entrepreneurs in startups, rather than existing market-leading companies. The business environment of market leaders does not allow them to pursue disruptive innovations when they first arise, because they are not profitable enough at first and because their development can take scarce resources away from sustaining innovations (which are needed to compete against current competition). Small teams are more likely to create disruptive innovations than large teams. A disruptive process can take longer to develop than by the conventional approach and the risk associated to it is higher than the other more incremental, architectural or evolutionary forms of innovations, but once it is deployed in the market, it achieves a much faster penetration and higher degree of impact on the established markets.",

The Japanese cultivar 'Hachiya' is widely grown. The fruit has a high tannin content, which makes the unripe fruit astringent and bitter. The tannin levels are reduced as the fruit matures. Persimmons like 'Hachiya' must be completely ripened before consumption. When ripe, this fruit comprises thick, pulpy jelly encased in a waxy thin-skinned shell.[citation needed]\n\nCommercially and in general, there are two types of persimmon fruit: astringent and non-astringent.\n\nThe heart-shaped Hachiya is the most common variety of astringent persimmon. Astringent persimmons contain very high levels of soluble tannins and are unpalatable if eaten before completely softened. The astringency of tannins is removed in various ways. Examples include ripening by exposure to light for several days and wrapping the fruit in paper (probably because this increases the ethylene concentration of the surrounding air).\n\nThe non-astringent persimmon is squat like a tomato and is most commonly sold as fuyu. Non-astringent persimmons are not actually free of tannins as the term suggests but rather are far less astringent before ripening and lose more of their tannic quality sooner.

        "answer": "Yes, they are.",
        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nWe introduce 4 BAE attack modes by replacing and inserting tokens, all of which are almost always stronger than previous baselines on 7 text classification datasets.",

It is commonly used to train and evaluate neural network models that generate image descriptions (e.g. BIBREF2 ). An untested assumption behind the dataset is that the descriptions are based on the images, and nothing else. Here are the authors (about the Flickr8K dataset, a subset of Flickr30K):\n“By asking people to describe the people, objects, scenes and activities that are shown in a picture without giving them any further information about the context in which the picture was taken, we were able to obtain conceptual descriptions that focus only on the information that can be obtained from the image alone.” BIBREF1 \nWhat this assumption overlooks is the amount of interpretation or recontextualization carried out by the annotators. Let us take a concrete example. Figure FIGREF1 shows an image from the Flickr30K dataset.\nThis image comes with the five descriptions below. All but the first one contain information that cannot come from the image alone. Relevant parts are highlighted in bold:\nWe need to understand that the descriptions in the Flickr30K dataset are subjective descriptions of events. This can be a good thing: the descriptions tell us what are the salient parts of each image to the average human annotator. So the two humans in Figure FIGREF1 are relevant, but the two soap dispensers are not. But subjectivity can also result in stereotypical descriptions, in this case suggesting that the male is more likely to be the manager, and the female is more likely to be the subordinate. rashtchian2010collecting do note that some descriptions are speculative in nature, which they say hurts the accuracy and the consistency of the descriptions. But the problem is not with the lack of consistency here. Quite the contrary: the problem is that stereotypes may be pervasive enough for the data to be consistently biased. And so language models trained on this data may propagate harmful stereotypes, such as the idea that women are less suited for leadership positions.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices. I will build on earlier work on linguistic bias in general BIBREF3 , providing examples from the Flickr30K data, and present a taxonomy of unwarranted inferences. Finally, I will discuss several methods to analyze the data in order to detect biases.\nRashtchian et al.

        "evidence": "As presented in this section, we conducted two series of experiments to analyze the property of IMTC. First, we qualitatively evaluated the diversity of options learned by IMTC with intrinsic rewards, without any extrinsic rewards. Second, we quantitatively test the reusability of learned options by). Also, we can see that the magnitude of intra-option policies tends larger with constant rewards. Right: Options learned by other methods. OC produces a dead option 3 that terminates everywhere and never-ending options 0 and 1. About intra-option policies, all methods successfully avoided learning the same policy, but they only have two directions.\ntask adaptation on a specific task. As a baseline of termination learning method, we compared our method with OC. OC is trained with VIC rewards during pre-training. We did not compare IMTC with TC because our TC implementation failed to learn options with relatively small termination regions as reported in the paper, and there is no official public code for TC 1 . During pre-training without extrinsic rewards, IMTC receives intrinsic rewards when the current option terminates. We compare three IMTC variants with different intrinsic rewards: (i) VIC, (ii) RVIC, and (iii) constant value (R IMTC = 0.01). Note that R IMTC = 0.01 is chosen from [0.1, 0.05, 0.01] based on the task adaptation results. We also compare IMTC with vanilla VIC and RVIC with fixed termination probabilities. We used ∀ x β o (x) = 0.1 since it performed the best in task adaptation experiments, while 0.05 was used in. Note that RVIC's objective I(X s ; O|x f ) is different from ours, while IMTC and VIC share almost the same objective. Thus, the use of VIC is more natural, and the combination with RVIC is tested to show the applicability of IMTC. Further details of our VIC and RVIC implementation are found in Appendix B. In order to check only the effect of the different methods for learning beta β o , the rest of the implementation is the same for all these methods. That is, OC, vanilla VIC, and vanilla RVIC are also based on PPO and advantage estimation methods in Section 4.2. In this section, we fix the number of options as |O| = 4 for all option-learning methods. We further investigated the effect of the number of options Appendix C, where we confirmed that |O| = 4 is sufficient for most domains. All environments that we used for experiments are implemented on the MuJoCo physics simulator. We further describe the details in Appendix C.\nOption Learning From Intrinsic Rewards We now qualitatively compare the options learned by IMTC with options of other methods. Learned options depend on the reward structure in the environment, which enables manually designing good reward functions for learning diverse options. Thus, we employed a reward-free RL setting where no reward is given to agents. Instead, each compared method uses some intrinsic rewards, as explained. We fix µ as µ(o|x) = 1 |O| in this experiment, since we assume that the future tasks are uniformly distributed. Intra-option policies are trained by PPO and independent GAE (8). We show network architectures and hyperparameters in Appendix C. We set the episode length to 1 × 10 4 , i.e., an agent is reset to its starting position after 1 × 10 4 steps. For all visualizations, we chose the best one from five independent runs with different random seeds.  We visualized learned options in PointReach environment shown in Figure. In this environment, an agent controls the ball initially placed at the center of the room. The state space consists of positions (x, y) and velocities (∆x, ∆y) of an agent, and the action space consists of acceralations ( ∆x ∆t , ∆y ∆t ). Figure shows the options learned in this environment after 4 × 10 6 steps. Each arrow represents the mean value of intra-option policies, and the heatmaps represent β o . In this experiment, we observed the effect of IMTC clearly, for both termination regions and intra-option policies. Interestingly, we don't see clear differences between options learned with VIC and RVIC rewards, while constant rewards tend to make options peaker. OC failed to learn meaningful termination regions: option 0 and 1 never terminate, and option 3 terminates almost everywhere. This result confirms that IMTC can certainly diversify options. Moreover, compared to vanilla VIC and RVIC, intra-option policies learned by IMTC with VIC or RVIC rewards are clearer, in terms of both the magnitude and directions of policies. We believe that this is because diversifying termination regions gives more biased samples to the option classifiers employed by VIC and RVIC. Figure Transferring skills via task adaptation Now we quantitatively test the reusability of learned options by task adaptation with specific reward functions. Specifically, we first trained agents with intrinsic rewards as per the previous section. Then we transferred agents to an environment with the same state and action space but with external rewards. We prepared multiple reward functions, which we call tasks, for each domain and evaluated the averaged performance over tasks. We compare IMTC with OC, vanilla VIC, vanilla RVIC, and PPO without pre-training. Also, we compare three variants of IMTC with different intrinsic rewards during pre-training. For a fair comparison, UGAE (9) and PPO are used for all options learning methods. Note that we found UGAE is very effective in this experiments, as we show the ablation study in Appendix C.6. For vanilla VIC and vanilla RVIC, termination probability is fixed to 0.1 through pre-training and task adaptation. -greedy based on Q O with = 0.1 is used as the option selection policy µ. We hypothesize that diverse options learned by IMTC can help quickly adapt to given tasks, supposing the diversity of tasks.\nFigure shows all domains used for task adaptation experiments. For simplicity, all tasks have goalbased sparse reward functions. I.e., an agent receives R t = 1.0 when it satisfies a goal condition, and otherwise the control cost −0.0001 is given. Red circles show possible goal locations for each task. When the agent fails to reach the goal after 1000 steps, it is reset to a starting position. PointReach, SwimmerReach, and AntReach are simple navigation tasks where an agent aim to just navigate itself to the goal. We also prepared tasks with object manipulation: in PointBilliard and AntBilliard an agent aims to kick the blue ball to the goal position, and in PointPush and AntPush, it has to push the block out of the way to the goal. We pre-traine options learning agents for 4 × 10 6 environmental steps and additionally trained them for 1 × 10 6 steps for each task. Figure shows learning curves and scatter plots drawn from five independent runs with  different random seeds per domain. 2 Here, we observed that IMTC with VIC or RVIC rewards performed the best or was compatible with baselines. IMTC with VIC performed better than OC with VIC except for AntRearch, which backs up the effectiveness of diversifying termination regions for learning reusable options. Also, IMTC with VIC and IMTC with RCIC respectively performed better in most of the tasks than VIC and RVIC with fixed termination probabilities. This result suggests that IMTC can boost the performance of option learning methods based on option classifiers, even when the objective is different as with RVIC. On the other hand, IMTC with constant rewards (R IMTC = 0.01) performed worse than IMTC with VIC or RVIC rewards, although it also learned diverse options as we show in Figure, suggesting the importance of adjusting rewards. We further analyzed the evolution of intrinsic rewards of VIC and RVIC in Appendix C.5. In addition, we can observe that IMTC's performance is especially better than other methods in relatively complex PointBilliard, AntBilliard, and AntPush, where object manipulation is required. Considering that manipulated balls and boxes move faster than agents in these domains, a choice of options can lead to larger differences in the future state. IMTC is suitable to these domains since it maximizes the diversity of the resulting states, while PPO struggles to learn. Contrary, IMTC's performance is close to other methods in Reach tasks, where the goal states are relatively close to the starting states in terms of euclidian distances.\nGridworld experiments and limitation of the method Although IMTC successfully learned diverse options in MuJoCo experiments, our analysis in Figure shows the possibility of learning options that are not interesting but have large MI. We further investigated this possibility by visualizing options in a classical four rooms gridworld in Appendix C.8. Interestingly, we observed that IMTC could fall into diverse but unmeaningful options in that environment. We believe that IMTC is often sufficient in a large environment where a randomly-initialized agent rarely gets the same trajectory. However, when the number of possible trajectories is small, diversifying the destinations could be insufficient. In such cases, it can be necessary to extend IMTC to diversify trajectories as done in.\nFigure 5 shows learning curves and scatter plots drawn from five independent runs with different random seeds per domain.",

        "evidence": "Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and sold in a specific time period by a country or countries, generally \"without double counting the intermediate goods and services used up to produce them\".[citation needed] GDP is most often used by the government of a single country to measure its economic health. Due to its complex and subjective nature, this measure is often revised before being considered a reliable indicator.[citation needed] GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore, using a basis of GDP per capita at purchasing power parity (PPP) may be more useful when comparing living standards between nations, while nominal GDP is more useful comparing national economies on the international market. Total GDP can also be broken down into the contribution of each industry or sector of the economy. The ratio of GDP to the total population of the region is the per capita GDP (also called the Mean Standard of Living).\n\nGDP definitions are maintained by a number of national and international economic organizations. The Organisation for Economic Co-operation and Development (OECD) defines GDP as \"an aggregate measure of production equal to the sum of the gross values added of all resident and institutional units engaged in production and services (plus any taxes, and minus any subsidies, on products not included in the value of their outputs)\". An IMF publication states that, \"GDP measures the monetary value of final goods and services—that are bought by the final user—produced in a country in a given period of time (say a quarter or a year).\"\n\nGDP is often used as a metric for international comparisons as well as a broad measure of economic progress. It is often considered to be the world's most powerful statistical indicator of national development and progress. However, critics of the growth imperative often argue that GDP measures were never intended to measure progress, and leave out key other externalities, such as resource extraction, environmental impact and unpaid domestic work. Critics frequently propose alternative economic models such as doughnut economics which use other measures of success or alternative indicators such as the OECD's Better Life Index as better approaches to measuring the effect of the economy on human development and well being.",

        "answer": "Detection engineering is a new approach to threat detection. More than just writing detection rules, detection engineering is a process—applying systems thinking and engineering to more accurately detect threats. The goal is to create an automated system of threat detection which is customizable, flexible, repeatable, and produces high quality alerts for security teams to act upon. Detection engineering is not yet a mature discipline with consistent methods and predictable results, but pioneers in the field are working towards this goal. There is not a lot written about the concept right now, no go-to standards or frameworks. It appears companies are developing their own approaches to incorporate the concept to improve their detection and response capabilities. \n\nA concept called detection-as-code (DaC), first coined by Anton Chuvakin in 2020, is at the heart of detection engineering, and points to the idea that detections should be treated as code. Essentially, it is about applying software engineering best practices to detections using modern agile CI/CD processes. \n\nThe benefits Of Detection Engineering include 1) reduced mean-time-to-response through automation of detections, 2) detections are more relevant to the environment, 3) the process is structured, repeatable, and informs workflows, 4) detection rules and analytics are version controlled, reused, and modified as needed, 5) Peer review and automated testing are part of the process, to catch mistakes and gaps.",

        "question": "Which countries today were commonly part of the Fertile Crescent in history?",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

Most of the grammatical error correction systems use classification and rule-based approaches for correcting specific error types. However, these systems use several linguistic cues as features. The standard linguistic analysis tools like part-of-speech (POS) taggers and parsers are often trained on well-formed text and perform poorly on ungrammatical text. This introduces further errors and limits the performance of rule-based and classification approaches to GEC. As a consequence, the phrase-based statistical machine translation (SMT) approach to GEC has gained popularity because of its ability to learn text transformations from erroneous text to correct text from error-corrected parallel corpora without any additional linguistic information. They are also not limited to specific error types. Currently, many state-of-the-art GEC systems are based on SMT or use SMT components for error correction BIBREF0 , BIBREF1 , BIBREF2 . In this paper, grammatical error correction includes correcting errors of all types, including word choice errors and collocation errors which constitute a large class of learners' errors.\nWe model our GEC system based on the phrase-based SMT approach.

        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ).

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.",

We report the percentile and count of features resulting in the first occurrence of the highest average F1-score for each class.\nAll experiments were programmed using scikit-learn 0.18.\nThe initial matrices of almost 17,000 features were reduced by eliminating features that only occurred once in the full dataset, resulting in 5,761 features. We applied Chi-Square feature selection and plotted the top-ranked subset of features for each percentile (at 5 percent intervals cumulatively added) and evaluated their predictive contribution using the support vector machine with linear kernel and stratified, 5-fold cross validation.\nIn Figure 2, we observed optimal F1-score performance using the following top feature counts: no evidence of depression: F1: 87 (15th percentile, 864 features), evidence of depression: F1: 59 (30th percentile, 1,728 features), depressive symptoms: F1: 55 (15th percentile, 864 features), depressed mood: F1: 39 (55th percentile, 3,168 features), disturbed sleep: F1: 46 (10th percentile, 576 features), and fatigue or loss of energy: F1: 72 (5th percentile, 288 features) (Figure 1).

In contrast, peak F1-score performances occurred at moderate percentiles for evidence of depression (30th percentile) and depressed mood (55th percentile) suggesting that more features are needed to reach optimal performance. However, one notable difference between these two classes is the dramatic F1-score improvements for depressed mood i.e., 20 point increase from the 1st percentile to the 20th percentile compared to the more gradual F1-score improvements for evidence of depression i.e., 11 point increase from the 1st percentile to the 20th percentile. This finding suggests that for identifying depressed mood a variety of features are needed before incremental gains are observed.\nWe applied Chi-Square feature selection and plotted the top-ranked subset of features for each percentile (at 5 percent intervals cumulatively added) and evaluated their predictive contribution using the support vector machine with linear kernel and stratified, 5-fold cross validation.",

The left blocks and the right blocks form two QANets, each of which takes a document and a question as the input and outputs an answer. In QANet, firstly, an embedding encoder obtains word and character embeddings for each word in INLINEFORM0 or INLINEFORM1 and then models the temporal interactions between words and refines word vectors to contextualized word representations. All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention. The intuition here is that convolution components can model local interactions and self-attention components focus on modeling global interactions. The context-query attention layer generates the question-document similarity matrix and computes the question-aware vector representations of the context words. After that, a model encoder layer containing seven encoder blocks captures the interactions among the context words conditioned on the question. Finally, the output layer predicts a start position and an end position in the document to extract the answer span from the document.\nAll encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention.",

        "evidence": "The advantage of SLASH lies in the efficient integration of neural, probabilistic and symbolic computations. To emphasize this, we conduct a variety of experimental evaluations.\nExperimental Details. We use two benchmark data sets, namely for the task of MNIST-Addition and a variant of the ShapeWorld data set for For ShapeWorld experiments, we generate a data set we refer to as ShapeWorld4. Images of ShapeWorld4 contain between one and four objects, with each object consisting of four attributes: a color (red, blue, green, gray, brown, magenta, cyan or yellow), a shade (bright, or dark), a shape (circle, triangle or square) and a size (small or big). Thus, each object can be created from 84 different combinations of attributes. Fig. depicts an example image.\nWe measure performance via classification accuracies in the MNIST-Addition task. In our Shape-World4 experiments, we present the average precision. We refer to appendix B for the SLASH programs and queries of each experiment, and appendix C for a detailed description of hyperparameters and further details.\nEvaluation 1: SLASH outperforms SOTA DPPLs in MNIST-Addition. The task of MNIST-Addition is to predict the sum of two MNIST digits, presented only as raw images. During test time, however, a model should classify the images directly. Thus, although a model does not receive explicit information about the depicted digits, it must learn to identify digits via indirect feedback on the sum prediction.\nWe compare the test accuracy after convergence between the three DPPLs: DeepProbLog, NeurASP and SLASH, using a probabilistic circuit (PC) or a deep neural network (DNN) as NPP. Notably, the DNN used in SLASH (DNN) is the LeNet5 model of DeepProbLog and NeurASP. We note that when using the PC as NPP, we have also extracted conditional class probabilities P (C|X), by marginalizing the class variables C to acquire the normalization constant P (X) from the joint P (X, C), and calculating P (X|C).\nThe results can be seen in Tab. 1a. We observe that training SLASH with a DNN NPP produces SOTA accuracies compared to DeepProbLog and NeurASP, confirming that SLASH's batch-wise loss computation leads to improved performances. We further observe that the test accuracy of SLASH with a PC NPP is slightly below the other DPPLs, however we argue that this may be since a PC, in comparison to a DNN, is learning a true mixture density rather than just conditional probabilities. The advantages of doing so will be investigated in the next experiments. Note that, optimal architecture search for PCs, e.g. for computer vision, is an open research question.These evaluations show SLASH's advantages on the benchmark MNIST-Addition task. Additional benefits will be made clear in the following experiments.\nEvaluation 2: Handling Missing Data with SLASH. SLASH offers the advantage of its flexibility to use various kinds of NPPs. Thus, in comparison to previous DPPLs, one can easily integrate NPPs into SLASH that perform joint probability estimation. For this evaluation, we consider the task of MNIST-Addition with missing data. We trained SLASH (PC) and DeepProbLog with the MNIST-Addition task with images in which a percentage of pixels per image has been removed. It is important to mention here that whereas DeepProbLog handles the missing data simply as background pixels, SLASH (PC) specifically models the missing data as uncertain data by marginalizing the denoted pixels at inference time. We use DeepProbLog here representative of DPPLs without true density estimation. The results can be seen in Tab. 1b for 50%, 80%, 90% and 97% missing pixels per image. We observe that at 50%, DeepProbLog and SLASH produce almost equal accuracies. With 80% percent missing pixels, there is a substantial difference in the ability of the two DPPLs to correctly classify images, with SLASH being very stable. By further increasing the percentage of missing pixels, this difference becomes even more substantial with SLASH still reaching a 82% test accuracy even when 97% of the pixels per image are missing, whereas DeepProbLog degrades to an average of 32% test accuracy. We further note that SLASH, in comparison to DeepProbLog, produces largely reduced standard deviations over runs.\nThus, by utilizing the power of true density estimation SLASH, with an appropriate NPP, can produce more robust results in comparison to other DPPLs. Further, we refer to Appendix D, which contains results of additional experiments where training is performed with the full MNIST data set whereas only the test set entails different rates of missing pixels.\nEvaluation 3: Improved Concept Learning via SLASH. We show that SLASH can be very effective for the complex task of set prediction, which previous DPPLs have not tackled. We revert to the ShapeWorld4 data set for this setting. For set prediction, a model is trained to predict the discrete attributes of a set of objects in an image (cf. Fig. for an example ShapeWorld4 image). The difficulty for the model lies therein that it must match an unordered set of corresponding attributes (with varying number of entities over samples) with its internal representations of the image.\nThe slot attention module introduced by allows for an attractive object-centric approach to this task. Specifically, this module represents a pluggable, differentiable module that can be easily added to any architecture and, through a competitive softmax-based attention mechanism, can enforce the binding of specific parts of a latent representation into permutation-invariant, taskspecific vectors, called slots.\nIn our experiments, we wish to show that by adding logical constraints to the training setting, one can improve the overall performances and generalization properties of such a model. For this, we train SLASH with NPPs as depicted in Fig. consisting of a shared slot encoder and separate PCs, each modelling the mixture of latent slot variables and the attributes of one category, e.g. color.\nFor ShapeWorld4, we thereby have altogether four NPPs. SLASH is trained via queries of the kind exemplified in Fig. in the Appendix. We refer to this configuration as SLASH Attention.\nWe compare SLASH Attention to a baseline slot attention encoder using an MLP and Hungarian loss for predicting the object properties from the slot encodings as in. The results of these experiments can be found in Fig. (top). We observe that the average precision after convergence on the held-out test set with SLASH Attention is greatly improved to that of the baseline model. Additionally, in Fig. we observe that SLASH Attention reaches the average precision value of the baseline model in much fewer number of epochs. Thus, we can summarize that adding logical knowledge in the training procedure via SLASH can greatly improve the capabilities of a neural module for set prediction.\nEvaluation 4: Improved Compositional Generalization with SLASH. To test the hypothesis that SLASH Attention possesses improved generalization properties in comparison to the baseline model, we ran experiments on a variant of ShapeWorld4 similar to the CLEVR Compositional Generalization Test (CoGenT). The goal of CoGenT is to investigate a model's ability to handle novel combinations of attributes that were not seen during training.\nFor this purpose, we established two conditions within a ShapeWorld4 CoGenT data set: Condition (A) -the training and test data set contains squares with the colors gray, blue, brown, or yellow, triangles with the colors red, green, magenta, or cyan and circles of all colors. Condition (B) -the training set is as in Condition (A). However, the test set contains squares with the colors red, green, magenta, or cyan, triangles with the colors gray, blue, brown, or yellow and circles of all colors. The goal is to investigate how well a model can generalize that, e.g., also squares can have the color red, although never having seen evidence for this during training.\nThe resulting average precision test scores are presented in Fig. (bottom). We observe that, even though the SLASH Program used for this experiment was not explicitly written to handle composition generalization, SLASH Attention shows greatly improved generalization capabilities. This can be seen in the approx. 13% higher average precision scores on the Condition (B) test set in comparison to the baseline model. Importantly, this trend still holds even when subtracting the higher precision scores observed in Condition (A).\nTo summarize our findings from the experiments on set prediction: we observe that adding prior knowledge in the form of logical constraints via SLASH can greatly improve a neural module in terms of performance and generalizability. On a side note: training neural networks for novel tasks, often involves defining explicit loss functions, e.g. Hungarian loss for set prediction. In contrast with SLASH, no matter the choice of NPP and underlying task, the training loss remains the same. Task-related requirements simply need to be added as lines of code to the SLASH program. This additionally highlights SLASH's versatility and flexibility.\nThe results can be seen in Tab. 1a. We observe that training SLASH with a DNN NPP produces SOTA accuracies compared to DeepProbLog and NeurASP, confirming that SLASH’s batch-wise loss computation leads to improved performances.",

        "evidence": "",
        "answer": "Ah, winter! It’s time to put on your long underwear. Slip in some wool socks and a sweater. Climb into your snowpants. Pull down your stocking cap. Grab your fi shing rod and bait bucket.\nThere’s ice on the lake, and it’s the season to enjoy a true Minnesota adventure, —ice fishing. Don’t worry about getting cold or bored on a frozen lake. Ice fishing is both easy and exciting. It’s fun to hike across the ice imagining hungry sunnies or walleyes lurking below. It’s an adventure to hang out around an ice hole with friends and family, telling stories and holding a funny looking fishing rod as you wait for a bite. And it’s thrilling when your bobber suddenly  vanishes down the hole, and you pull a slippery fish from the water with a splash. So grab a grown-up, a Thermos of hot cocoa, and get ready for an ice fishing adventure.\n\nStart with a visit to your local bait store or DNR Fisheries office. Folks there can tell you in which lakes the fish are biting and where you can get onto the lake. They can also tell you where the ice is most likely to be OK. Wind, warm weather, underwater springs, and currents can all make ice unsafe. Ice must be at least 4 inches thick before you walk on it. (See Be Safe, page 45.) Once you know the ice is thick enough, you can go find a fishing spot. Here are three ways to look: § If you know where fish hang out in summer, go there. Fish usually go to the same places in winter. § Pick up a lake map at the bait shop or DNR and look for shallow areas or drop-offs (where the bottom gets deep quickly). Fish are more likely to be there. § Look for anglers congregated at the best fishing holes. Ask if you can fish near them. (It’s not polite to drill holes too close to other anglers.) If the fish aren’t biting in one spot, try another.\n\nYou can use a regular reel, or some anglers use a device called a tip-up instead. A tipup has two sticks. One lies across the hole. The other points down into the hole and has a spool with line. When a fish takes your bait, a flag springs up from the stick across the hole. Then you pull the fish up with the line. Tip-ups are fun because you can watch them while reading a book or tossing a Frisbee.\n\n1.\tCut a Hole.\na.\tTo catch fish through the ice, you must first drill a hole. To drill a hole, ice anglers use a tool called an auger, which looks like a giant screw with a sharp blade on the end. Another handy tool is a spud, a long-handled chisel with a sharp blade for checking ice thickness and chipping extra ice from the hole. Anglers use a scoop, a big spoon with holes, to clean out ice shavings.\n\n2.\t Find the Depth\na.\tIf you know the depth of the water, you have a better idea what fish to fish for. Bluegills and northerns like shallow water. Look for walleyes in deeper water. Some anglers use an electronic fish locator or a lead weight on a hook. You can also tie a string to a weight, hold the loose end in one hand, and drop the weigh to the bottom. Then measure the length of string that’s down the hole. The simplest solution is to use a weighted hook, which drops to the bottom. Then you reel it up to fish as far off the bottom as you like. \n\n3.\tLand your Catch\na.\tWhen you feel a fish on the line, reel it up steadily but not too fast because you might yank out the hook. When you see the fish, ask your adult fishing buddy to lift it out. After landing a fish, remove it from the hook. It’s easier to get a hook out with pliers than with your hands in cold weather. If the fish is too big or too small to keep, return it to the water. Or put your catch in a bucket or a snowbank. Watch out for dogs! A dog might try to run away with your catch! It happens. \n\n4.\tUse Good Manners\na.\tBe polite and don’t disturb your fellow anglers with loud talk or goofing around. Always pick up your trash and anything else you brought. Remember: Anything you leave on the lake will go into the water when the ice melts.",

        "answer": "It aims to identify predicate-argument structures and assign meaningful labels to them.",
        "evidence": "Encoding of words is perhaps the most important step towards a successful end-to-end natural language processing application. Although word embeddings have been shown to provide benefit to such models, they commonly treat words as the smallest meaning bearing unit and assume that each word type has its own vector representation. This assumption has two major shortcomings especially for languages with rich morphology: (1) inability to handle unseen or out-of-vocabulary (OOV) word-forms (2) inability to exploit the regularities among word parts. The limitations of word embeddings are particularly pronounced in sentence-level semantic tasks, especially in languages where word parts play a crucial role. Consider the Turkish sentences “Köy+lü-ler (villagers) şehr+e (to town) geldi (came)” and “Sendika+lı-lar (union members) meclis+e (to council) geldi (came)”. Here the stems köy (village) and sendika (union) function similarly in semantic terms with respect to the verb come (as the origin of the agents of the verb), where şehir (town) and meclis (council) both function as the end point. These semantic similarities are determined by the common word parts shown in bold. However ortographic similarity does not always correspond to semantic similarity. For instance the ortographically similar words knight and night have large semantic differences. Therefore, for a successful semantic application, the model should be able to capture both the regularities, i.e, morphological tags and the irregularities, i.e, lemmas of the word.\nMorphological analysis already provides the aforementioned information about the words. However access to useful morphological features may be problematic due to software licensing issues, lack of robust morphological analyzers and high ambiguity among analyses. Character-level models (CLM), being a cheaper and accessible alternative to morphology, have been reported as performing competitively on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 . However the extent to which these tasks depend on morphology is small; and their relation to semantics is weak. Hence, little is known on their true ability to reveal the underlying morphological structure of a word and their semantic capabilities. Furthermore, their behaviour across languages from different families; and their limitations and strengths such as handling of long-range dependencies, reaction to model complexity or performance on out-of-domain data are unknown. Analyzing such issues is a key to fully understanding the character-level models.\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:\n $[$ Villagers $]$ comers came $[$ to town $]$ end point\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis. The gold morphology serves as the upper bound for us to compare and analyze the performances of character-level models on languages of varying morphological typologies. We carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology. In regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English. Our experiments and analysis reveal insights such as:\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:  $[$ Villagers $]$ comers came $[$ to town $]$ end point",

        "answer": "They use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nThird, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate,  we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output.",

This extended feature-set improved the success rate of the sarcasm detector by 3.7%, over the best available system. Using cognitive features in an NLP Processing system like ours is the first proposal of its kind.\nOur general approach may be useful in other NLP sub-areas like sentiment and emotion analysis, text summarization and question answering, where considering textual clues alone does not prove to be sufficient.

        "evidence": "Machine reading comprehension and question answering has becomes a crucial application problem in evaluating the progress of AI system in the realm of natural language processing and understanding BIBREF0 . The computational linguistics communities have devoted significant attention to the general problem of machine reading comprehension and question answering.\nHowever, most of existing reading comprehension tasks only focus on shallow QA tasks that can be tackled very effectively by existing retrieval-based techniques BIBREF1 . For example, recently we have seen increased interest in constructing extractive machine reading comprehension datasets such as SQuAD BIBREF2 and NewsQA BIBREF3 . Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nOur model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.",

The study examined a large tooth that had spent over 500 days in the mouth of a Tyrannosaurus rex with no evidence of substantial wear, which is consistent with all findings of teeth found in the theropod family of dinosaurs. When contrasted with alligators and crocodiles, who have no lips and have more easily damaged teeth the theory says the evidence points to theropods, including Tyrannosaurus rex did indeed have lips.

Though there are many strategies to beat procrastination, the effectiveness of these strategies is largely dependent on the individual and his/her/their circumstances. Here are some popular strategies to beat procrastination:\n\n1. Set realistic, specific, and time-bound goals. The best goals should have some built-in time delays, but not too much, as to maintain some urgency. Large goals should also be broken into achievable chunks. \n\n2. Limit your access to distracting media. Making use of your device's focus modes, or locking away your device all together when working can prevent you from being distracted while executing tasks\n\n3. Make the rewards of accomplishing goals tangible and more immediate. A popular strategy for this is temptation bundling, where you bundle a behavior that is good for you in the long-run with a behavior that feels good in the short-run. For example, you may only allow yourself to watch YouTube videos while you are folding laundry.\n\n4. Use support systems. Often, using peers, family, or other individuals in your support system to help hold you accountable is an effective way to encourage task accomplishment. This method also promotes social interaction and continuous discussion of goals with others. As a caveat, you should not become reliant on this method, as it can create burdens on the other individuals in your support system",

        "evidence": "A running of the bulls (Spanish: encierro, from the verb encerrar, 'to corral, to enclose'; Occitan: abrivado, literally 'haste, momentum'; Catalan: correbous, 'run-bulls') is an event that involves running in front of a small group of bulls, typically six but sometimes ten or more, that have been let loose on sectioned-off streets in a town, usually as part of a summertime festival. Particular breeds of cattle may be favored, such as the toro bravo in Spain, also often used in post-run bullfighting, and Camargue cattle in Occitan France, which are not fought. Bulls (non-castrated male cattle) are typically used in such events.\n\nThe most famous bull-run is the encierro held in Pamplona during the nine-day festival of Sanfermines in honor of Saint Fermin. It has become a major global tourism event, today very different from the traditional, local festival. More traditional summer bull-runs are held in other places such as towns and villages across Spain and Portugal, in some cities in Mexico, and in the Occitan (Camargue) region of southern France. Bull-running was formerly also practiced in rural England, most famously at Stamford until 1837.",

Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (up to and including the so-called countervalue targeting of civilians with nuclear weapons), de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.\n\nFour countries besides the five recognized Nuclear Weapons States have acquired, or are presumed to have acquired, nuclear weapons: India, Pakistan, North Korea, and Israel. None of these four is a party to the NPT, although North Korea acceded to the NPT in 1985, then withdrew in 2003 and conducted its first nuclear test in 2006. One critique of the NPT is that the treaty is discriminatory in the sense that only those countries that tested nuclear weapons before 1968 are recognized as nuclear weapon states while all other states are treated as non-nuclear-weapon states who can only join the treaty if they forswear nuclear weapons.\n\nResearch into the development of nuclear weapons was initially undertaken during World War II by the United States (in cooperation with the United Kingdom and Canada), Germany, Japan, and the USSR. The United States was the first and is the only country to have used a nuclear weapon in war, when it used two bombs against Japan in August 1945. After surrendering to end the war, Germany and Japan ceased to be involved in any nuclear weapon research. In August 1949, the USSR tested a nuclear weapon, becoming the second country to detonate a nuclear bomb. The United Kingdom first tested a nuclear weapon in October 1952. France first tested a nuclear weapon in 1960. The People's Republic of China detonated a nuclear weapon in 1964. India conducted its first nuclear test in 1974, which prompted Pakistan to develop its own nuclear program and, when India conducted a second series of nuclear tests in 1998, Pakistan followed with a series of tests of its own. In 2006, North Korea conducted its first nuclear test.",

        "question": "What are the two main challenges when designing data-to-text models?",
        "answer": "1) understanding structured data and 2) generating associated descriptions",
        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions.",

At the heart of the Transformer lie multi-head attention mechanisms: each word is represented by multiple different weighted averages of its relevant context. As suggested by recent works on interpreting attention head roles, separate attention heads may learn to look for various relationships between tokens BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9.\nThe attention distribution of each head is predicted typically using the softmax normalizing transform. As a result, all context words have non-zero attention weight. Recent work on single attention architectures suggest that using sparse normalizing transforms in attention mechanisms such as sparsemax – which can yield exactly zero probabilities for irrelevant words – may improve performance and interpretability BIBREF12, BIBREF13, BIBREF14. Qualitative analysis of attention heads BIBREF0 suggests that, depending on what phenomena they capture, heads tend to favor flatter or more peaked distributions.\nRecent works have proposed sparse Transformers BIBREF10 and adaptive span Transformers BIBREF11. However, the “sparsity\" of those models only limits the attention to a contiguous span of past tokens, while in this work we propose a highly adaptive Transformer model that is capable of attending to a sparse set of words that are not necessarily contiguous.

        "evidence": "The goal of sentence simplification is to compose complex sentences into simpler ones so that they are more comprehensible and accessible, while still retaining the original information content and meaning. Sentence simplification has a number of practical applications. On one hand, it provides reading aids for people with limited language proficiency BIBREF1 , BIBREF2 , or for patients with linguistic and cognitive disabilities BIBREF3 . On the other hand, it can improve the performance of other NLP tasks BIBREF4 , BIBREF5 , BIBREF6 . Prior work has explored monolingual machine translation (MT) approaches, utilizing corpora of simplified texts, e.g., Simple English Wikipedia (SEW), and making use of statistical MT models, such as phrase-based MT (PBMT) BIBREF7 , BIBREF8 , BIBREF9 , tree-based MT (TBMT) BIBREF10 , BIBREF11 , or syntax-based MT (SBMT) BIBREF12 .\nInspired by the success of neural MT BIBREF13 , BIBREF14 , recent work has started exploring neural simplification with sequence to sequence (Seq2seq) models, also referred to as encoder-decoder models. Nisioi et al. Nisioi:17 implemented a standard LSTM-based Seq2seq model and found that they outperform PBMT, SBMT, and unsupervised lexical simplification approaches. Zhang and Lapata BIBREF15 viewed the encoder-decoder model as an agent and employed a deep reinforcement learning framework in which the reward has three components capturing key aspects of the target output: simplicity, relevance, and fluency. The common practice for Seq2seq models is to use recurrent neural networks (RNNs) with Long Short-Term Memory BIBREF16 or Gated Recurrent Unit BIBREF17 for the encoder and decoder BIBREF18 , BIBREF15 . These architectures were designed to be capable of memorizing long-term dependencies across sequences. Nevertheless, their memory is typically small and might not be enough for the simplification task, where one is confronted with long and complicated sentences. In this study, we go beyond the conventional LSTM/GRU-based Seq2seq models and propose to use a memory-augmented RNN architecture called Neural Semantic Encoders (NSE). This architecture has been shown to be effective in a wide range of NLP tasks BIBREF0 . The contribution of this paper is twofold:\n(1) First, we present a novel simplification model which is, to the best of our knowledge, the first model that use memory-augmented RNN for the task. We investigate the effectiveness of neural Seq2seq models when different neural architectures for the encoder are considered. Our experiments reveal that the NseLstm model that uses an NSE as the encoder and an LSTM as the decoder performed the best among these models, improving over strong simplification systems. (2) Second, we perform an extensive evaluation of various approaches proposed in the literature on different datasets. Results of both automatic and human evaluation show that our approach is remarkably effective for the task, significantly reducing the reading difficulty of the input, while preserving grammaticality and the original meaning. We further discuss some advantages and disadvantages of these approaches.\nResults of both automatic and human evaluation show that our approach is remarkably effective for the task, significantly reducing the reading difficulty of the input, while preserving grammaticality and the original meaning.",

Briony attends a party in her honor at the Tallis family home, where the extended Tallis children perform The Trials of Arabella, the play that 13-year-old Briony had written and unsuccessfully attempted to stage with her cousins in the summer of 1935. Leon and Pierrot are in attendance, Jackson is fifteen years deceased, and Lola is alive but does not attend. Finally, Briony reveals to the reader that Robbie Turner died of septicaemia on the beaches of Dunkirk, that Cecilia was killed several months later when a bomb destroyed Balham Underground station during the Blitz, and that Briony's story of seeing them together in 1940 was a fabrication. Briony did attend Lola's wedding to Paul Marshall, but confesses she was too \"cowardly\" to visit the recently bereaved Cecilia to make amends. The novel, which she says is factually true apart from Robbie and Cecilia being reunited, is her lifelong attempt at \"atonement\" for what she did to them. Briony justifies her invented happy ending by saying she does not see what purpose it would serve to give readers a \"pitiless\" story.

        "evidence": "Subword segmentation has become a standard preprocessing step in many neural approaches to natural language processing (NLP) tasks, e.g Neural Machine Translation (NMT) BIBREF0 and Automatic Speech Recognition (ASR) BIBREF1. Word level modeling suffers from sparse statistics, issues with Out-of-Vocabulary (OOV) words, and heavy computational cost due to a large vocabulary. Word level modeling is particularly unsuitable for morphologically rich languages, but subwords are commonly used for other languages as well. Subword segmentation is best suited for languages with agglutinative morphology.\nWhile rule-based morphological segmentation systems can achieve high quality, the large amount of human effort needed makes the approach problematic, particularly for low-resource languages. The systems are language dependent, necessitating use of multiple tools in multilingual setups. As a fast, cheap and effective alternative, data-driven segmentation can be learned in a completely unsupervised manner from raw corpora. Unsupervised morphological segmentation saw much research interest until the early 2010's; for a survey on the methods, see hammarstrom2011unsupervised. Semi-supervised segmentation with already small amounts of annotated training data was found to improve the accuracy significantly when compared to a linguistic segmentation; see ruokolainen2016comparative for a survey. While this line of research has been continued in supervised and more grammatically oriented tasks BIBREF2, the more recent work on unsupervised segmentation is less focused on approximating a linguistically motivated segmentation. Instead, the aim has been to tune subword segmentations for particular applications. For example, the simple substitution dictionary based Byte Pair Encoding segmentation algorithm BIBREF3, first proposed for NMT by sennrich2015neural, has become a standard in the field. Especially in the case of multilingual models, training a single language-independent subword segmentation method is preferable to linguistic segmentation BIBREF4.\nIn this study, we compare three existing and one novel subword segmentation method, all sharing the use of a unigram language model in a generative modeling framework. The previously published methods are Morfessor Baseline BIBREF5, Greedy Unigram Likelihood BIBREF6, and SentencePiece BIBREF7.

        "answer": "Structure information and text description.",
        "evidence": "Knowledge graphs have been proved to benefit many artificial intelligence applications, such as relation extraction, question answering and so on. A knowledge graph consists of multi-relational data, having entities as nodes and relations as edges. An instance of fact is represented as a triplet (Head Entity, Relation, Tail Entity), where the Relation indicates a relationship between these two entities. In the past decades, great progress has been made in building large scale knowledge graphs, such as WordNet BIBREF0 , Freebase BIBREF1 . However, most of them have been built either collaboratively or semi-automatically and as a result, they often suffer from incompleteness and sparseness.\nThe knowledge graph completion is to predict relations between entities based on existing triplets in a knowledge graph. Recently, a new powerful paradigm has been proposed to encode every element (entity or relation) of a knowledge graph into a low-dimensional vector space BIBREF2 , BIBREF3 . The representations of entities and relations are obtained by minimizing a global loss function involving all entities and relations. Therefore, we can do reasoning over knowledge graphs through algebraic computations.\nAlthough existing methods have good capability to learn knowledge graph embeddings, it remains challenging for entities with few or no facts BIBREF4 . To solve the issue of KB sparsity, many methods have been proposed to learn knowledge graph embeddings by utilizing related text information BIBREF5 , BIBREF6 , BIBREF7 . These methods learn joint embedding of entities, relations, and words (or phrases, sentences) into the same vector space. However, there are still three problems to be solved. (1) The combination methods of the structural and textual representations are not well studied in these methods, in which two kinds of representations are merely aligned on word level or separate loss function. (2) The text description may represent an entity from various aspects, and various relations only focus on fractional aspects of the description. A good encoder should select the information from text in accordance with certain contexts of relations. Figure 1 illustrates the fact that not all information provided in its description are useful to predict the linked entities given a specific relation. (3) Intuitively, entities with many facts depend more on well-trained structured representation while those with few or no facts might be largely determined by text descriptions. A good representation should learn the most valuable information by balancing both sides.\nIn this paper, we propose a new deep architecture to learn the knowledge representation by utilizing the existing text descriptions of entities. Specifically, we learn a joint representation of each entity from two information sources: one is structure information, and another is its text description. The joint representation is the combination of the structure and text representations with a gating mechanism. The gate decides how much information from the structure or text representation will carry over to the final joint representation. In addition, we also introduce an attention mechanism to select the most related information from text description under different contexts. Experimental results on link prediction and triplet classification show that our joint models can handle the sparsity problem well and outperform the baseline method on all metrics with a large margin.\nOur contributions in this paper are summarized as follows.\nSpecifically, we learn a joint representation of each entity from two information sources: one is structure information, and another is its text description. The joint representation is the combination of the structure and text representations with a gating mechanism.",

Blockbuster collected customers' $800 million in late fees in 2006 alone.\n\nNetflix’s mail-in-DVD service offered a lower performance for the customers as they had to pick titles on their portal pre- and wait for 2 to 3 days before they arrived in their mailbox.

After disputes between students and Oxford townsfolk in 1209, some academics fled north-east to Cambridge where they established what became the University of Cambridge. The two English ancient universities share many common features and are jointly referred to as Oxbridge.\n\nThe university is made up of thirty-nine semi-autonomous constituent colleges, five permanent private halls, and a range of academic departments which are organised into four divisions. All the colleges are self-governing institutions within the university, each controlling its own membership and with its own internal structure and activities. All students are members of a college. It does not have a main campus, and its buildings and facilities are scattered throughout the city centre. Undergraduate teaching at Oxford consists of lectures, small-group tutorials at the colleges and halls, seminars, laboratory work and occasionally further tutorials provided by the central university faculties and departments.

        "question": "What are the Binary Paragraph Vector models?",
        "answer": "It is an extensions to PV-DBOW and PVDM that learn short binary codes for text documents.",
        "evidence": "One of the significant challenges in contemporary information processing is the sheer volume of available data. BIBREF0 , for example, claim that the amount of digital data in the world doubles every two years. This trend underpins efforts to develop algorithms that can efficiently search for relevant information in huge datasets. One class of such algorithms, represented by, e.g., Locality Sensitive Hashing BIBREF1 , relies on hashing data into short, locality-preserving binary codes BIBREF2 . The codes can then be used to group the data into buckets, thereby enabling sublinear search for relevant information, or for fast comparison of data items. Most of the algorithms from this family are data-oblivious, i.e. can generate hashes for any type of data. Nevertheless, some methods target specific kind of input data, like text or image.\nIn this work we focus on learning binary codes for text documents. An important work in this direction has been presented by BIBREF3 . Their semantic hashing leverages autoencoders with sigmoid bottleneck layer to learn binary codes from a word-count bag-of-words (BOW) representation. Salakhutdinov & Hinton report that binary codes allow for up to 20-fold improvement in document ranking speed, compared to real-valued representation of the same dimensionality. Moreover, they demonstrate that semantic hashing codes used as an initial document filter can improve precision of TF-IDF-based retrieval. Learning binary representation from BOW, however, has its disadvantages. First, word-count representation, and in turn the learned codes, are not in itself stronger than TF-IDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such high-dimensional vectors is impractical. Salakhutdinov & Hinton restricted the BOW vocabulary in their experiments to 2000 most frequent words.\nBinary codes have also been applied to cross-modal retrieval where text is one of the modalities. Specifically, BIBREF4 incorporated tag information that often accompany text documents, while BIBREF5 employed siamese neural networks to learn single binary representation for text and image data.\nRecently several works explored simple neural models for unsupervised learning of distributed representations of words, sentences and documents. BIBREF6 proposed log-linear models that learn distributed representations of words by predicting a central word from its context (CBOW model) or by predicting context words given the central word (Skip-gram model). The CBOW model was then extended by BIBREF7 to learn distributed representations of documents. Specifically, they proposed Paragraph Vector Distributed Memory (PV-DM) model, in which the central word is predicted given the context words and the document vector. During training, PV-DM learns the word embeddings and the parameters of the softmax that models the conditional probability distribution for the central words. During inference, word embeddings and softmax weights are fixed, but the gradients are backpropagated to the inferred document vector. In addition to PV-DM, Le & Mikolov studied also a simpler model, namely Paragraph Vector Distributed Bag of Words (PV-DBOW). This model predicts words in the document given only the document vector. It therefore disregards context surrounding the predicted word and does not learn word embeddings. Le & Mikolov demonstrated that paragraph vectors outperform BOW and bag-of-bigrams in information retrieval task, while using only few hundreds of dimensions. These models are also amendable to learning and inference over large vocabularies. Original CBOW network used hierarchical softmax to model the probability distribution for the central word. One can also use noise-contrastive estimation BIBREF8 or importance sampling BIBREF9 to approximate the gradients with respect to the softmax logits.\nAn alternative approach to learning representation of pieces of text has been recently described by BIBREF10 . Networks proposed therein, inspired by the Skip-gram model, learn to predict surrounding sentences given the center sentence. To this end, the center sentence is encoded by an encoder network and the surrounding sentences are predicted by a decoder network conditioned on the center sentence code. Once trained, these models can encode sentences without resorting to backpropagation inference. However, they learn representations at the sentence level but not at the document level.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PV-DM that learn short binary codes for text documents. One inspiration for binary paragraph vectors comes from a recent work by BIBREF11 on learning binary codes for images. Specifically, we introduce a sigmoid layer to the paragraph vector models, and train it in a way that encourages binary activations. We demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes. We also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora. Finally, we study models that simultaneously learn short binary codes for document filtering and longer, real-valued representations for ranking. While BIBREF11 employed a supervised criterion to learn image codes, binary paragraph vectors remain unsupervised models: they learn to predict words in documents.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PVDM that learn short binary codes for text documents.",

        "question": "What does BERT consist of as its main building blocks?",
        "answer": "Self-attention, feed-forward layers, residual connections and layer normalization",
        "evidence": "Because our work builds heavily upon BERT, we provide a brief summary of its features. BERT is built upon the Transformer architecture BIBREF0, which uses self-attention, feed-forward layers, residual connections and layer normalization as the main building blocks. It has two pre-training objectives:\nMasked language modelling - some of the words in a sentence are being masked and the model has to predict them based on the context (note the difference from the typical autoregressive language model training objective);\nNext sentence prediction - given two input sequences, decide whether the second one is the next sentence or not.\nBERT has been shown to beat the state-of-the-art performance on 11 tasks with no modifications to the model architecture, besides adding a task-specific output layer BIBREF1. We follow same procedure suggested in BIBREF1 for our tasks. Fig. FIGREF8 shows the BERT model for classification. We obtain two kinds of representation from BERT: pooled output from last transformer block, denoted by H, and posterior probabilities, denoted by P. There are two variants of BERT - BERT-Base and BERT-Large. In this work we are using BERT-Base for faster training and experimentation, however, our methods are applicable to BERT-Large as well. BERT-Base and BERT-Large are different in model parameters such as number of transformer blocks, number of self-attention heads. Total number of parameters in BERT-Base are 110M and 340M in BERT-Large.\nBERT suffers from major limitations in terms of handling long sequences. Firstly, the self-attention layer has a quadratic complexity $O(n^2)$ in terms of the sequence length $n$ BIBREF0. Secondly, BERT uses a learned positional embeddings scheme BIBREF1, which means that it won't likely be able to generalize to positions beyond those seen in the training data.\nTo investigate the effect of fine-tuning BERT on task performance, we use either the pre-trained BERT weights, or the weights from a BERT fine-tuned on the task-specific dataset on a segment-level (i.e. we preserve the original label but fine-tune on each segment separately instead of on the whole text sequence). We compare these results to using the fine-tuned segment-level BERT predictions directly as inputs to the next layer.\nGiven that BERT is limited to a particular input length, we split the input sequence into segments of a fixed size with overlap. For each of these segments, we obtain H or P from BERT model. We then stack these segment-level representations into a sequence, which serves as input to a small (100-dimensional) LSTM layer. Its output serves as a document embedding. Finally, we use two fully connected layers with ReLU (30-dimensional) and softmax (the same dimensionality as the number of classes) activations to obtain the final predictions.\nWith this approach, we overcome BERT's computational complexity, reducing it to $O(n/k * k^2) = O(nk)$ for RoBERT, with $k$ denoting the segment size (the LSTM component has negligible linear complexity $O(k)$). The positional embeddings are also no longer an issue.\nGiven that Transformers' edge over recurrent networks is their ability to effectively capture long distance relationships between words in a sequence BIBREF0, we experiment with replacing the LSTM recurrent layer in favor of a small Transformer model (2 layers of transformer building block containing self-attention, fully connected, etc.). To investigate if preserving the information about the input sequence order is important, we also build a variant of ToBERT which learns positional embeddings at the segment-level representations (but is limited to sequences of length seen during the training).\nToBERT's computational complexity $O(\\frac{n^2}{k^2})$ is asymptotically inferior to RoBERT, as the top-level Transformer model again suffers from quadratic complexity in the number of segments. However, in practice this number is much smaller than the input sequence length (${\\frac{n}{k}} << n$), so we haven't observed performance or memory issues with our datasets.\nBERT is built upon the Transformer architecture [1], which uses self-attention, feed-forward layers, residual connections and layer normalization as the main building blocks.",

        "question": "Based on the reference text, provide a bulleted list summarizing Newton's three laws of motion",
        "evidence": "First\nTranslated from the Latin, Newton's first law reads,\n\nEvery body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.: 114 \nNewton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. In the absence of outside influences, a body's motion preserves the status quo.\n\nThe modern understanding of Newton's first law is that no inertial observer is privileged over any other. The concept of an inertial observer makes quantitative the everyday idea of feeling no effects of motion. For example, a person standing on the ground watching a train go past is an inertial observer. If the observer on the ground sees the train moving smoothly in a straight line at a constant speed, then a passenger sitting on the train will also be an inertial observer: the train passenger feels no motion. The principle expressed by Newton's first law is that there is no way to say which inertial observer is \"really\" moving and which is \"really\" standing still. One observer's state of rest is another observer's state of uniform motion in a straight line, and no experiment can deem either point of view to be correct or incorrect. There is no absolute standard of rest.[note 4]\n\nSecond\nThe change of motion of an object is proportional to the force impressed; and is made in the direction of the straight line in which the force is impressed.: 114 \nBy \"motion\", Newton meant the quantity now called momentum, which depends upon the amount of matter contained in a body, the speed at which that body is moving, and the direction in which it is moving. In modern notation, the momentum of a body is the product of its mass and its velocity:\n\nNewton's second law, in modern form, states that the time derivative of the momentum is the force:\nIf the mass m does not change with time, then the derivative acts only upon the velocity, and so the force equals the product of the mass and the time derivative of the velocity, which is the acceleration:\nAs the acceleration is the second derivative of position with respect to time, this can also be written.\n\nThe forces acting on a body add as vectors, and so the total force on a body depends upon both the magnitudes and the directions of the individual forces. When the net force on a body is equal to zero, then by Newton's second law, the body does not accelerate, and it is said to be in mechanical equilibrium. A state of mechanical equilibrium is stable if, when the position of the body is changed slightly, the body remains near that equilibrium. Otherwise, the equilibrium is unstable.\n\nA common visual representation of forces acting in concert is the free body diagram, which schematically portrays a body of interest and the forces applied to it by outside influences. For example, a free body diagram of a block sitting upon an inclined plane can illustrate the combination of gravitational force, \"normal\" force, friction, and string tension.[note 5]\n\nNewton's second law is sometimes presented as a definition of force, i.e., a force is that which exists when an inertial observer sees a body accelerating. In order for this to be more than a tautology — acceleration implies force, force implies acceleration — some other statement about force must also be made. For example, an equation detailing the force might be specified, like Newton's law of universal gravitation. By inserting such an expression for \n into Newton's second law, an equation with predictive power can be written.[note 6] Newton's second law has also been regarded as setting out a research program for physics, establishing that important goals of the subject are to identify the forces present in nature and to catalogue the constituents of matter.[note 7]\n\nThird\nTo every action, there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.: 116 \n\nOverly brief paraphrases of the third law, like \"action equals reaction\" might have caused confusion among generations of students: the \"action\" and \"reaction\" apply to different bodies. For example, consider a book at rest on a table. The Earth's gravity pulls down upon the book. The \"reaction\" to that \"action\" is not the support force from the table holding up the book, but the gravitational pull of the book acting on the Earth.[note 8]\n\nNewton's third law relates to a more fundamental principle, the conservation of momentum. The latter remains true even in cases where Newton's statement does not, for instance when force fields as well as material bodies carry momentum, and when momentum is defined properly, in quantum mechanics as well.[note 9]\nBy Newton's second law, the first term is the total force upon the first body, and the second term is the total force upon the second body. If the two bodies are isolated from outside influences, the only force upon the first body can be that from the second, and vice versa. By Newton's third law, these forces have equal magnitude but opposite direction, so they cancel when added, and \n→{\\vec {p}} is constant. Alternatively, if \n→{\\vec {p}} is known to be constant, it follows that the forces have equal magnitude and opposite direction.",

Here, the idea is to achieve the best compromise between search space (number of candidates) and maximum performance (recall).",

The input papers ranged from 6 to 8 pages and were converted from PDF format to plain text using an off-the-shelf tool. The only preprocessing applied is a systematic dehyphenation at line breaks and removal of author-assigned keyphrases. Scientific articles were selected from four different research areas as defined in the ACM classification, and were equally distributed into training (144 articles) and test (100 articles) sets. Gold standard keyphrases are composed of both author-assigned keyphrases collected from the original PDF files and reader-assigned keyphrases provided by student annotators.\nLong documents such as those in the SemEval-2010 benchmark dataset are notoriously difficult to handle due to the large number of keyphrase candidates (i.e. phrases that are eligible to be keyphrases) that the systems have to cope with BIBREF6 . Furthermore, noisy textual content, whether due to format conversion errors or to unusable elements (e.g. equations), yield many spurious keyphrase candidates that negatively affect keyphrase extraction performance. This is particularly true for systems that make use of core NLP tools to select candidates, that in turn exhibit poor performance on degraded text. Filtering out irrelevant text is therefore needed for addressing these issues.\nIn this study, we concentrate our effort on re-assessing keyphrase extraction performance on three increasingly sophisticated levels of document preprocessing described below.\nTable shows the average number of sentences and words along with the maximum possible recall for each level of preprocessing. The maximum recall is obtained by computing the fraction of the reference keyphrases that occur in the documents.

Level 3 preprocessing drastically reduce the number of words to less than a quarter of the original amount while interestingly still preserving high recall.\nLevel 3: As pointed out by (Treeratpituk et al., 2010; Nguyen and Luong, 2010; Wang and Li, 2010; Eichler and Neumann, 2010; El-Beltagy and Rafea, 2010), considering only the keyphrase dense parts of the scientific articles allows to improve keyphrase extraction performance. Accordingly we follow previous work and further abridge the input text from level 2 preprocessed documents to the following: title, headers, abstract, introduction, related work, background and conclusion. Here, the idea is to achieve the best compromise between search space (number of candidates) and maximum performance (recall).",

        "evidence": "Abstractive Summarization. Abstractive summarization aims to generate coherent summaries with high readability, and has seen increasing interest and improved performance due to the emergence of seq2seq models BIBREF8 and attention mechanisms BIBREF9. For example, BIBREF0, BIBREF2, and BIBREF1 in addition to using encoder-decoder model with attention, they used pointer networks to solve the out of vocabulary issue, while BIBREF0 used coverage mechanism to solve the problem of word repetition. In addition, BIBREF2 and BIBREF10 used reinforcement learning in an end-to-end setting.\nTo our knowledge, training such neural abstractive summarization models in low resource domains using domain transfer has not been thoroughly explored on domains different than news. For example, BIBREF4 reported the results of training on CNN/DM data while evaluating on DUC data without any tuning. Note that these two datasets are both in the news domain, and both consist of well written, structured documents. The domain transfer experiments of BIBREF1 similarly used two different news summarization datasets (CNN/DM and NYT). Our work differs in several ways from these two prior domain transfer efforts. First, our experiments involve two entirely different domains: news and student reflections. Unlike news, student reflection documents lack global structure, are repetitive, and contain many sentence fragments and grammatical mistakes. Second, the prior approaches either trained a part of the model using NYT data while retaining the other part of the model trained only on CNN/DM data BIBREF1, or didn't perform any tuning at all BIBREF4. In contrast, we do the training in two consecutive phases, pretraining and fine tuning. Finally, BIBREF1 reported that while training with domain transfer outperformed training only on out-of-domain data, it was not able to beat training only on in-domain data. This is likely because their in and out-of-domain data sizes are comparable, unlike in our case of scarce in-domain data.\nIn a different approach to abstractive summarization, BIBREF11 developed a soft template based neural method consisting of an end-to-end deep model for template retrieval, reranking and summary rewriting. While we also develop a template based model, our work differs in both model structure and purpose.\nData Synthesis. Data synthesis for text summarization is underexplored, with most prior work focusing on machine translation, and text normalization. BIBREF12 proposed doing data augmentation through word replacement, using WordNet BIBREF13 and vector space similarity, respectively. We will use a WordNet replacement method as a baseline synthesis method in the experiments described below. In contrast, BIBREF14 synthesized/augmented data through back-translation and word replacement using language models. BIBREF15 is another recent work that was done in parallel and is very close to ours. However, in addition to the difference in both our and their model, we think it might be infeasible to back generate student reflections from a human summary, especially an abstractive one.\nFirst, our experiments involve two entirely different domains: news and student reflections.",

I have divided these descriptions into two classes: linguistic bias and unwarranted inferences.

The latter corresponds to the tendency of annotators to go beyond what the physical data can tell us, and expand their descriptions based on their past experiences and knowledge of the world. Acknowledging these phenomena is important, because on the one hand it helps us think about what is learnable from the data, and on the other hand it serves as a warning: if we train and evaluate language models on this data, we are effectively teaching them to be biased.\nI have also looked at methods to detect stereotype-driven descriptions, but due to the richness of language it is difficult to find an automated measure. Depending on whether your goal is production or interpretation, it may either be useful to suppress or to emphasize biases in human language. Finally, I have discussed stereotyping behavior as the addition of a contextual layer on top of a more basic description.

The oceans that stretch from Northern California through to Mexico provide a rich wildlife habitat and amazing surf spots.  The Sierras, the mountain range a short drive away, allow for skiing and snowboarding for a majority of the year at locations that have been home to the Winter Olympics. The Central Valley is the home of farmlands and ranches and seem to stretch for miles. California provides natural wonders from forests to desserts to mountain peaks. \n\nCalifornia's climate in most parts is mild throughout the year. It is joked about by many, that it has one season. However, with the onset of global warming the weather patterns have seen a change.  The extreme droughts have been followed by extreme rain and flooding.  Although there has been more extreme weather across the globe, California still has a predominantly mild climate for a majority of the year making it a top destination for those looking for sunshine.\n\nCalifornia has been known as the Golden State.  It has provided golden opportunities for many who have come from all over the world to make their dreams come true. During the Gold Rush in the 1800s, miners came in from all over to find gold nuggets in the Sacramento Valley. Hollywood, the home of movies and television for the world, has been the mecca of many young person looking to find success in acting and celebrity since the early 1900s.  Silicon Valley has birthed some of the most successful companies in the world, showcasing the talents of students and entrepreneurs, changing the trajectory and pace of innovation. California is the home to many of the most transformative companies providing a wealth of job opportunities. California is the showcase of the American dream. \n\nOne can spend years visiting landmarks and interesting locations in California. The Golden Gate Bridge is a must see in San Francisco, it is one of the most historic bridges and the doorway to the San Francisco Bay. Yosemite is a glorious national park and home to gorgeous waterfall, hiking and Half Dome. Along the coast, visiting Big Sur is a must, showcasing the sky high redwoods and a priceless view of the coastline. Palm Springs provides a fun dessert location that is the home to music festivals, incredible golfing and natural hot springs. Another point of interest, Lake Tahoe, a gorgeous Lake that is truly breath taking.  It is surrounded by mountains of snow in the winter and the home to water skiers in the summer. This is just a taste of the amazing locations California has to offer. \n\nCalifornia truly has a treasure trove of benefits for visitors and residents, however it has been struggling with issues that can threaten its future and make it difficult for those that choose to call it home. California has very high taxes for both residents and business owners.  The population boom has also created a lack of low cost housing, California is home to the some of the highest housing prices in the United States. The high taxes and high priced housing makes this state out of reach for many. Additionally, the state needs to work on investments in public education, infrastructure and homelessness which have all been suffering in recent years.\n\nDespite some of it's struggles, the Golden State continues to be golden due to amazing locations, an incredible climate, a diverse population and unmatched opportunity.

        "evidence": "Our datasets can be used for various hate speech tasks. In this paper, we focus on generative hate speech intervention.\nThe goal of this task is to generate a response to hate speech that can mitigate its use during a conversation. The objective can be formulated as the following equation:\nwhere $c$ is the conversation, $r$ is the corresponding intervention response, and $D$ is the dataset. This task is closely related to the response generation and dialog generation, though several differences exist including dialog length, language cadence, and word imbalances. As a baseline, we chose the most common methods of these two tasks, such as Seq2Seq and VAE, to determine the initial feasibility of automatically generate intervention responses. More recent Reinforcement Learning method for dialog generation BIBREF21 can also be applied to this task with slight modification. Future work will explore more complex, and unique models.\nSimilar to BIBREF21, a generative model is considered as an agent. However, different from dialog generation, generative intervention does not have multiple turns of utterance, so the action of the agent is to select a token in the response. The state of the agent is given by the input posts and the previously generated tokens. Another result due to this difference is that the rewards with regard to ease of answering or information flow do not apply to this case, but the reward for semantic coherence does. Therefore, the reward of the agent is:\nwhere $rw(c,r)$ is the reward with regard to the conversation $c$ and its reference response $r$ in the dataset. $p(r|c)$ denotes the probability of generating response $r$ given the conversation $c$, and $p_{back}(c|r)$ denotes the backward probability of generating the conversation based on the response, which is parameterized by another generation network. The reward is a weighted combination of these two parts, which are observed after the agent finishing generating the response. We refer the readers to BIBREF21 for details.\nThe decoder consists of 2 GRU layers followed by a 3-layer MLP (Multi-Layer Perceptron).",

        "question": "Without quoting directly from the text give me a summary of Cesar Chavez greatest achievements.",
        "evidence": "Cesar Chavez (born Cesario Estrada Chavez /ˈtʃɑːvɛz/; Spanish: [ˈt͡ʃaβes]; March 31, 1927 – April 23, 1993) was an American labor leader and civil rights activist. Along with Dolores Huerta, he co-founded the National Farm Workers Association (NFWA), which later merged with the Agricultural Workers Organizing Committee (AWOC) to become the United Farm Workers (UFW) labor union. Ideologically, his world-view combined leftist politics with Catholic social teachings.\n\nBorn in Yuma, Arizona to a Mexican American family, Chavez began his working life as a manual laborer before spending two years in the United States Navy. Relocating to California, where he married, he got involved in the Community Service Organization (CSO), through which he helped laborers register to vote. In 1959, he became the CSO's national director, a position based in Los Angeles. In 1962, he left the CSO to co-found the NFWA, based in Delano, California, through which he launched an insurance scheme, a credit union, and the El Malcriado newspaper for farmworkers. Later that decade he began organizing strikes among farmworkers, most notably the successful Delano grape strike of 1965–1970. Amid the grape strike his NFWA merged with Larry Itliong's AWOC to form the UFW in 1967. Influenced by the Indian independence leader Mahatma Gandhi, Chavez emphasized direct but nonviolent tactics, including pickets and boycotts, to pressure farm owners into granting strikers' demands. He imbued his campaigns with Roman Catholic symbolism, including public processions, masses, and fasts. He received much support from labor and leftist groups but was monitored by the Federal Bureau of Investigation (FBI).\n\nIn the early 1970s, Chavez sought to expand the UFW's influence outside California by opening branches in other U.S. states. Viewing illegal immigrants as a major source of strike-breakers, he also pushed a campaign against illegal immigration into the U.S., which generated violence along the U.S.-Mexico border and caused schisms with many of the UFW's allies. Interested in co-operatives as a form of organization, he established a remote commune at Keene. His increased isolation and emphasis on unrelenting campaigning alienated many California farmworkers who had previously supported him and by 1973 the UFW had lost most of the contracts and membership it won during the late 1960s. His alliance with California Governor Jerry Brown helped ensure the passing of the California Agricultural Labor Relations Act of 1975, although the UFW's campaign to get its measures enshrined in California's constitution failed. Influenced by the Synanon religious organization, Chavez re-emphasized communal living and purged perceived opponents. Membership of the UFW dwindled in the 1980s, with Chavez refocusing on anti-pesticide campaigns and moving into real-estate development, generating controversy for his use of non-unionized laborers.\n\nA controversial figure, UFW critics raised concerns about Chavez's autocratic control of the union, the purges of those he deemed disloyal, and the personality cult built around him, while farm-owners considered him a communist subversive. He became an icon for organized labor and leftist groups in the U.S. and posthumously became a \"folk saint\" among Mexican Americans. His birthday is a federal commemorative holiday in several U.S. states, while many places are named after him, and in 1994 he posthumously received the Presidential Medal of Freedom.",

        "evidence": "Natural language inference (NLI) is a widely-studied problem in natural language processing. It aims at comparing a pair of sentences (i.e. a premise and a hypothesis), and inferring the relationship between them (i.e., entailment, neutral and contradiction). Large-scaled datasets like SNLI BIBREF0 and MultiNLI BIBREF1 have been created by crowd-sourcing and fertilized NLI research substantially.\nHowever, several works BIBREF2, BIBREF3, BIBREF4 have pointed out that crowd-sourcing workers have brought a bias pattern named annotation artifacts in these NLI datasets. Such artifacts in hypotheses can reveal the labels and make it possible to predict the labels solely by looking at the hypotheses. For example, models trained on SNLI with only the hypotheses can achieve an accuracy of 67.0%, despite the always predicting the majority-class baseline is only 34.3% BIBREF2.\nClassifiers trained on NLI datasets are supposed to make predictions by understanding the semantic relationships between given sentence pairs. However, it is shown that models are unintentionally utilizing the annotation artifacts BIBREF4, BIBREF2. If the evaluation is conducted under a similar distribution as the training data, e.g., with the given testing set, models will enjoy additional advantages, making the evaluation results over-estimated. On the other hand, if the bias pattern cannot be generalized to the real-world, it may introduce noise to models, thus hurting the generalization ability.\nIn this paper, we use cross-dataset testing to better assess models' generalization ability. We investigate the impacts of annotation artifacts in cross-dataset testing. Furthermore, we propose an easy-adopting debiasing training framework, which doesn't require any additional data or annotations, and apply it to the high-performing Densely Interactive Inference Network BIBREF5. Experiments show that our method can effectively mitigate the bias pattern and improve the cross-dataset generalization ability of models. To the best of our knowledge, our work is the first attempt to alleviate the annotation artifacts without any extra resources.\nFurthermore, we propose an easy-adopting debiasing training framework, which doesn't require any additional data or annotations, and apply it to the high-performing Densely Interactive Inference Network.",

        "question": "Is it common to have source and assisting languages with different word order in a practical setting?",
        "answer": "Yes, it is.",
        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nIn a practical setting, it is not uncommon to have source and assisting languages with different word order.",

        "question": "What are redo logs in Oracle RDBMS?",
        "evidence": "In the Oracle RDBMS environment, redo logs comprise files in a proprietary format which log a history of all changes made to the database. Each redo log file consists of redo records. A redo record, also called a redo entry, holds a group of change vectors, each of which describes or represents a change made to a single block in the database.\n\nFor example, if a user UPDATEs a salary-value in a table containing employee-related data, the DBMS generates a redo record containing change-vectors that describe changes to the data segment block for the table. And if the user then COMMITs the update, Oracle generates another redo record and assigns the change a \"system change number\" (SCN).\n\nWhenever something changes in a datafile, Oracle records the change in the redo log. The name redo log indicates its purpose: If the database crashes, the RDBMS can redo (re-process) all changes on datafiles which will take the database data back to the state it was when the last redo record was written. DBAs use the views V$LOG, V$LOGFILE, V$LOG_HISTORY and V$THREAD to find information about the redo log of the database. Each redo log file belongs to exactly one group (of which at least two must exist). Exactly one of these groups is the CURRENT group (can be queried using the column status of v$log). Oracle uses that current group to write the redo log entries. When the group is full, a log switch occurs, making another group the current one. Each log switch causes checkpoint, however, the converse is not true: a checkpoint does not cause a redo log switch. One can also manually cause a redo-log switch using the ALTER SYSTEM SWITCH LOGFILE command.",

        "answer": "Yes.",
        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score.",

        "evidence": "Prior work has suggested that persistent learning is the most effective method for learning a valid EBM density. Furthermore, works that learn a valid density have avoided rejuvenation because the incorporation of newly rejuvenated samples into the persistent bank ensures that EBM updates will always include samples that are not at the steady-state. However, persistent learning without rejuvenation has shortcomings mentioned in Section 3. We present hypothesized conditions for learning a valid density that motivate the design of our MCMC initialization:\n• After a certain point in training, all samples used to update the EBM must be approximate steadystate samples of the current model p(x; θ). • Persistent samples that are newly rejuvenated (up to about 50K Langevin steps since rejuvenation, and possibly many more) cannot be approximate steady-state samples for any known rejuvenation sources, including data, generators, and noise. • Persistent samples that have undergone sufficiently many lifetime Langevin updates for a model whose weights are changing very slowly can be approximate steady-state samples.\nFigure: Visualization of our longrun initializatin procedure. Newly rejuvenated samples must remain the the burnin bank until they have approach the model steady-state, at which point they move to the update bank to be used for model gradients.\nBoth the second and third point are corroborated by prior work as well as our own observations. The third point means that persistent states updated with shortrun Langevin can eventually act as longrun Langevin samples if the optimizer learning rate is small, because the EBM samples in previous timesteps are essentially samples from the current EBM.\nLearning a valid density that includes rejuvenation while satisfying the conditions above requires separating the newly rejuvenated samples from samples that are used to update the EBM. This leads us to introduce two persistent image banks: one for newly rejuvenated samples, and one for samples that will be used to update the EBM. Samples in the newly rejuvenated bank that have been updated sufficiently many times will eventually replace samples from the bank used to update the EBM, at which point newly rejuvenated states will be added to the burn-in bank. Figure shows a visualization of the MCMC initialization method. As in Section 3, we will use a pre-trained generator to efficiently obtain high-quality rejuvenated samples so that the generation process is fully synthetic, although data samples could be used as well. Our goal is to preserve the sample quality for an arbitrary number of MCMC steps. We note that this is a sufficient but not necessary condition for learning a valid EBM density. Nonetheless, stable sampling is an important step towards rigorous probabilistic EBMs. Even with our improved initialization, we find that extremely longrun trajectories of 1 million or more MCMC steps still tend to oversaturate, although to a much lesser degree. To further stabilize the appearance of extremely longrun Langevin samples, we include prior energy terms in the model. Our longrun EBMs have the form\nwhere U (x; θ) is the model whose weights are updated, U 0 (x; θ 0 ) is a prior EBM with fixed weights θ 0 and σ is a parameter controlling the strength of a Gaussian prior. We used a prior EBM in a shortrun manner. The role of the prior EBM is to provide some stability but also to provide a tendency to oversaturate at longer trajectories so that the current EBM learns to correct oversaturation. The Gaussian prior is meant to discourage unbounded activations outside of the image hypercube. Further discussion is in Appendix H. We find that including both of these terms significantly improves the ability to learn quality synthesis over long trajectories.\nAs in Section 3, we will use a pre-trained generator to efficiently obtain high-quality rejuvenated samples so that the generation process is fully synthetic, although data samples could be used as well. Our goal is to preserve the sample quality for an arbitrary number of MCMC steps.

Often referred to as the \"Fall Classic\", the modern World Series has been played every year since 1903 with two exceptions: in 1904, when the NL champion New York Giants declined to play the AL champion Boston Americans; and in 1994, when the series was canceled due to the players' strike.\n\nThe best-of-seven style has been the format of all World Series except in 1903, 1919, 1920, and 1921, when the winner was determined through a best-of-nine playoff. Although the large majority of contests have been played entirely during the month of October, a small number of Series have also had games played during September and November. The Series-winning team is awarded the Commissioner's Trophy. Players, coaches and others associated with the team are generally given World Series rings to commemorate their victory; however, they have received other items such as pocket watches and medallions in the past. The winning team is traditionally invited to the White House to meet the President of the United States.\n\nA total of 118 World Series have been contested through 2022, with the AL champion winning 67 and the NL champion winning 51. The New York Yankees of the AL have played in 40 World Series, winning 27 – the most championship appearances and most victories by any team amongst the major North American professional sports leagues. The Dodgers of the NL have the most losses with 14, while the Yankees have the most losses among AL teams with 13. The St. Louis Cardinals have won 11 championships, the most championships among NL clubs and second-most all-time behind the Yankees, and have made 19 total appearances, third-most among NL clubs. The Dodgers have represented the NL the most in the World Series with 21 appearances.\n\nThe Seattle Mariners are the only current MLB franchise that has never appeared in a World Series; the San Diego Padres, Colorado Rockies, Texas Rangers, Tampa Bay Rays, and Milwaukee Brewers have all played in the Series but have never won it. The Los Angeles Angels, Arizona Diamondbacks and Washington Nationals are the only teams who have won their only World Series appearance, and the Toronto Blue Jays and the Miami Marlins have won both of their World Series appearances. The Toronto Blue Jays are the only franchise from outside the United States to appear in and win a World Series, winning in 1992 and 1993. The Houston Astros are the only franchise to have represented both the NL (2005) and the AL (2017, 2019, 2021, 2022), winning the Series in 2017 and 2022.\n\nThe current (2022) World Series champions are the Houston Astros.",

        "evidence": "The word cookie dates from at least 1701 in Scottish usage where the word meant \"plain bun\", rather than thin baked good, and so it is not certain whether it is the same word. From 1808, the word \"cookie\" is attested \"...in the sense of \"small, flat, sweet cake\" in American English. The American use is derived from Dutch koekje \"little cake,\" which is a diminutive of \"koek\" (\"cake\"), which came from the Middle Dutch word \"koke\". Another claim is that the American name derives from the Dutch word koekje or more precisely its informal, dialect variant koekie which means little cake, and arrived in American English with the Dutch settlement of New Netherland, in the early 1600s.",

        "question": "What is the performance of the binary codes?",
        "answer": "Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower.",
        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nNote that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower.",

Under the RA-MDS setting, one should jointly consider news documents and reader comments when generating the summaries.\nOne challenge of the RA-MDS problem is how to conduct salience estimation by jointly considering the focus of news reports and the reader interests revealed by comments. Meanwhile, the model should be insensitive to the availability of diverse aspects of reader comments. Another challenge is that reader comments are very noisy, not fully grammatical and often expressed in informal expressions. Some previous works explore the effect of comments or social contexts in single document summarization such as blog summarization BIBREF7 , BIBREF8 . However, the problem setting of RA-MDS is more challenging because the considered comments are about an event which is described by multiple documents spanning a time period. Another challenge is that reader comments are very diverse and noisy. Recently, BIBREF9 employed a sparse coding based framework for RA-MDS jointly considering news documents and reader comments via an unsupervised data reconstruction strategy. However, they only used the bag-of-words method to represent texts, which cannot capture the complex relationship between documents and comments.\nRecently, BIBREF6 proposed a sentence salience estimation framework known as VAESum based on a neural generative model called Variational Auto-Encoders (VAEs) BIBREF10 , BIBREF11 . During our investigation, we find that the Gaussian based VAEs have a strong ability to capture the salience information and filter the noise from texts. Intuitively, if we feed both the news sentences and the comment sentences into the VAEs, commonly existed latent aspect information from both of them will be enhanced and become salient. Inspired by this consideration, to address the sentence salience estimation problem for RA-MDS by jointly considering news documents and reader comments, we extend the VAESum framework by training the news sentence latent model and the comment sentence latent model simultaneously by sharing the neural parameters. After estimating the sentence salience, we employ a phrase based compressive unified optimization framework to generate a final summary.\nThere is a lack of high-quality dataset suitable for RA-MDS. Existing datasets from DUC and TAC are not appropriate. Therefore, we introduce a new dataset for RA-MDS. We employed some experts to conduct the tasks of data collection, aspect annotation, and summary writing as well as scrutinizing. To our best knowledge, this is the first dataset for RA-MDS.\nOur contributions are as follows: (1) We investigate the RA-MDS problem and introduce a new dataset for the problem of RA-MDS. To our best knowledge, it is the first dataset for RA-MDS. (2) To tackle the RA-MDS, we extend a VAEs-based MDS framework by jointly considering news documents and reader comments. (3) Experimental results show that reader comments can improve the summarization performance, which also demonstrates the usefulness of the dataset.\nDuring our investigation, we find that the Gaussian based VAEs have a strong ability to capture the salience information and filter the noise from texts.",

Royal Navy submarines operating off the coast of Argentina could use electronic sensors in their periscopes to detect electronic signals from Argentine aircraft as they took off. These subs provided the fleet with enough advanced warning to launch Sea Harriers on interception missions. Consequently, an Argentine pilot needed to be ready to dogfight a Harrier, dodge surface-to-air missiles, and then pull off a low-level bombing run. All three of these tasks required a level of training that most Argentine pilots lacked. Argentina ran out of fighter jets before the British ran out of ships.",

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nIn this paper, we present BAE (BERT-based Adversarial Examples), a novel technique using the BERT masked language model (MLM) for word replacements to better fit the overall context of the English language.",

Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Spain, France, Portugal, and the United Kingdom.

Following BIBREF0, performance is evaluated using ROUGE (1, 2, and $L$) BIBREF22 on F1. The motivation for using domain transfer and data synthesis is our hypothesis (H1). Table TABREF13 supports this hypothesis. All ROUGE scores for PG-net that outperform all extractive baselines (in italics) involve tuning and/or use of synthesised data, except for one R-1 (row 18).\nAs for our second hypothesis (H2), table TABREF13 shows that it is a valid one. For PG-net, comparing the CNN/DM out-of-domain and Student Reflection in-domain results in rows (5 and 6) and (17 and 18) with their corresponding tuned results in rows 9 and 21, we see that fine tuning improves R-1, R-2, and R-$L$ for all courses (rows 5, 6, 9 and 17, 18, 21). Qualitatively, the examples presented in Table TABREF11 clearly show that tuning yields a more coherent and relevant summary. Over all courses, the tuned version of PG-net consistently outperforms the best baseline result for each metric (rows 9 vs. 1, 2, 3, 4 and 21 vs. 13, 14, 15, 16) except for R-2 in Stat2016.\nTo validate our next set of hypothesises (H3, H4. H5), we use the synthesized data in two settings: either using it for training (rows 7, 8 and 19, 20) or tuning (rows 10, 11 and 22, 23). Table TABREF13 supports H4 by showing that the proposed synthesis model outperforms the WordNet baseline in training (rows 7, 8 and 19, 20) except Stat2016, and tuning (10, 11 and 22, 23) over all courses. It also shows that while adding synthetic data from the baseline is not always helpful, adding synthetic data from the template model helps to improve both the training and the tuning process. In both CS and ENGR courses, tuning with synthetic data enhances all ROUGE scores compared to tuning with only the original data. (rows 9 and 11). As for Stat2015, R-1 and R-$L$ improved, while R-2 decreased. For Stat2016, R-2 and R-$L$ improved, and R-1 decreased (rows 21 and 23). Training with both student reflection data and synthetic data compared to training with only student reflection data yields similar improvements, supporting H3 (rows 6, 8 and 18, 20). While the increase in ROUGE scores is small, our results show that enriching training data with synthetic data can benefit both the training and tuning of other models. In general, the best results are obtained when using data synthesis for both training and tuning (rows 11 and 23), supporting H5.\nFinally, while the goal of our template model was to synthesize data, using it for summarization is surprisingly competitive, supporting H6. We believe that training the model with little data is doable due to the small number of parameters (logistic regression classifier only). While rows 12 and 24 are never the best results, they are close to the best involving tuning. This encourages us to enhance our template model and explore templates not so tailored to our data.\nHuman Evaluation Results. While automated evaluation metrics like ROUGE measure lexical similarity between machine and human summaries, humans can better measure how coherent and readable a summary is. Our evaluation study investigates whether tuning the PG-net model increases summary coherence, by asking evaluators to select which of three summaries for the same document they like most: the PG-net model trained on CNN/DM; the model trained on student reflections; and finally the model trained on CNN/DM and tuned on student reflections. 20 evaluators were recruited from our institution and asked to each perform 20 annotations. Summaries are presented to evaluators in random order. Evaluators are then asked to select the summary they feel to be most readable and coherent. Unlike ROUGE, which measures the coverage of a generated summary relative to a reference summary, our evaluators don't read the reflections or reference summary. They choose the summary that is most coherent and readable, regardless of the source of the summary. For both courses, the majority of selected summaries were produced by the tuned model (49% for CS and 41% for Stat2015), compared to (31% for CS and 30.9% for Stat2015) for CNN/DM model, and (19.7% for CS and 28.5% for Stat2015) for student reflections model. These results again suggest that domain transfer can remedy the size of in-domain data and improve performance.\nAll ROUGE scores for PG-net that outperform all extractive baselines (in italics) involve tuning and/or use of synthesised data, except for one R-1 (row 18).",

Unlike gases, plasma may self-generate magnetic fields and electric currents and respond strongly and collectively to electromagnetic forces. Plasma is very uncommon on Earth (except for the ionosphere), although it is the most common state of matter in the universe.\nSupercritical fluid: At sufficiently high temperatures and pressures, the distinction between liquid and gas disappears.\nDegenerate matter: matter under very high pressure, supported by the Pauli exclusion principle.\nElectron-degenerate matter: found inside white dwarf stars. Electrons remain bound to atoms but can transfer to adjacent atoms.\nNeutron-degenerate matter: found in neutron stars. Vast gravitational pressure compresses atoms so strongly that the electrons are forced to combine with protons via Inverse beta decay, resulting in a super dense conglomeration of neutrons. (Normally free neutrons outside an atomic nucleus will decay with a half-life of just under fifteen minutes, but in a neutron star, as in the nucleus of an atom, other effects stabilize the neutrons.)\nStrange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed.\nQuantum spin Hall state: a theoretical phase that may pave the way for developing electronic devices that dissipate less energy and generate less heat. This is a derivation of the quantum Hall state of matter.\nBose–Einstein condensate: a phase in which a large number of bosons all inhabit the same quantum state, in effect becoming one single wave/particle. This is a low-energy phase that can only be formed in laboratory conditions and at very low temperatures. It must be close to zero kelvin, or absolute zero. Satyendra Nath Bose and Albert Einstein predicted the existence of such a state in the 1920s, but it was not observed until 1995 by Eric Cornell and Carl Wieman.\nFermionic condensate: Similar to the Bose-Einstein condensate but composed of fermions, also known as Fermi-Dirac condensate. The Pauli exclusion principle prevents fermions from entering the same quantum state, but a pair of fermions can behave like a boson, and multiple such pairs can then enter the same quantum state without restriction.\nSuperconductivity: is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature. Superconductivity is the ground state of many elemental metals.\nSuperfluid: A phase achieved by a few cryogenic liquids at extreme temperature at which they become able to flow without friction. A superfluid can flow up the side of an open container and down the outside. Placing a superfluid in a spinning container will result in quantized vortices.\nSupersolid: similar to a superfluid, a supersolid can move without friction but retains a rigid shape.\nQuantum spin liquid: A disordered state in a system of interacting quantum spins which preserves its disorder to shallow temperatures, unlike other disordered states.\nString-net liquid: Atoms in this state have unstable arrangements, like a liquid, but are still consistent in the overall pattern, like a solid.\nTime crystals: A state of matter where an object can have movement even at its lowest energy state.\nRydberg polaron: A state of matter that can only exist at ultra-low temperatures and consists of atoms inside of atoms.\nBlack superionic ice: A state of matter that can exist under very high pressure while excited by super lasers.",

Supercritical fluid: Matter that lacks a clear distinction between being a gas and a liquid. This state is found at high temperatures and pressures.\n3. Degenerative Matter: A highly dense state of matter due to very high pressures. This state of matter is naturally found in stars in their final evolutionary states. \n4. Bose-Einstein condensate: A phase of matter in which a large number of bosons all inhabit the same quantum state. This phase requires temperatures near absolute zero of very low density gas.\n5. Fermionic condensate: Similar to Bose-Einstein condensate, except with fermions instead of bosons. \n6. Superconductivity: Certain elemental materials may achieve a ground state of superconductivity where there is no electrical resistance and magnetic flux fields are expelled. While most conductors will have reduced resistance as the temperature is lowered, superconductors will abruptly achieve zero resistance at a certain critical temperature. \n7. Superfluid: Some fluids may enter this state of matter where, at extremely low temperatures, they become able to flow without friction.\n8. Supersolid: Similar to a superfluid, except it can move without friction in a rigid, solid shape.\n9. Quantum spin liquid: A state of matter found in certain materials related to the quantum spin. In most magnetic materials, spins tend to form patterns based on how they interact with other neighboring spins. In a quantum spin liquid, however, they remain in a disordered state, never forming a pattern that prevents it from reaching a stable, ordered state.\n10.

As of 2022, Costco is the fifth largest retailer in the world  and is the world's largest retailer of choice and prime beef, organic foods, rotisserie chicken, and wine as of 2016. Costco is ranked #11 on the Fortune 500 rankings of the largest United States corporations by total revenue.\n\nCostco's worldwide headquarters are in Issaquah, Washington, an eastern suburb of Seattle, although its Kirkland Signature house label bears the name of its former location in Kirkland. The company opened its first warehouse (the chain's term for its retail outlets) in Seattle in 1983. Through mergers, however, Costco's corporate history dates back to 1976, when its former competitor Price Club was founded in San Diego, California. As of February 2023, Costco has 848 warehouses worldwide: 584 in the United States, 107 in Canada, 40 in Mexico, 31 in Japan, 29 in the United Kingdom, 18 in South Korea, 14 in Taiwan, 14 in Australia, four in Spain, two each in France and China, and one each in Iceland, New Zealand and Sweden.",

        "answer": "Lemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma.",
        "evidence": "* Equal contribution. Listing order is random.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma. More concretely, consider the English sentence: The bulls are running in Pamplona. A lemmatizer will seek to map each word to a form you may find in a dictionary—for instance, mapping running to run. This linguistic normalization is important in several downstream NLP applications, especially for highly inflected languages. Lemmatization has previously been shown to improve recall for information retrieval BIBREF0 , BIBREF1 , to aid machine translation BIBREF2 , BIBREF3 and is a core part of modern parsing systems BIBREF4 , BIBREF5 .\nHowever, the task is quite nuanced as the proper choice of the lemma is context dependent. For instance, in the sentence A running of the bulls took place in Pamplona, the word running is its own lemma, since, here, running is a noun rather than an inflected verb. Several counter-examples exist to this trend, as discussed in depth in haspelmath2013understanding. Thus, a good lemmatizer must make use of some representation of each word's sentential context. The research question in this work is, then, how do we design a lemmatization model that best extracts the morpho-syntax from the sentential context?\nRecent work BIBREF7 has presented a system that directly summarizes the sentential context using a recurrent neural network to decide how to lemmatize. As N18-1126's system currently achieves state-of-the-art results, it must implicitly learn a contextual representation that encodes the necessary morpho-syntax, as such knowledge is requisite for the task. We contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize. Indeed, to this end, we introduce a joint model for the introduction of morphology into a neural lemmatizer. A key feature of our model is its simplicity: Our contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model. However, despite the model's simplicity, it still achieves a significant improvement over the state of the art on our target task: lemmatization.\nExperimentally, our contributions are threefold. First, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora BIBREF8 . Second, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization. Finally, we provide a detailed error analysis indicating when and why morphological analysis helps lemmatization. We offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.\nOur system and pre-trained models on all languages in the latest version of the UD corpora are released at https://sigmorphon.github.io/sharedtasks/2019/task2/.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma.",

        "question": "What did the Triceratops use their horns for?",
        "evidence": "There has been much speculation over the functions of Triceratops' head adornments. The two main theories have revolved around use in combat and in courtship display, with the latter now thought to be the most likely primary function.\n\nEarly on, Lull postulated that the frills may have served as anchor points for the jaw muscles to aid chewing by allowing increased size and thus power for the muscles. This has been put forward by other authors over the years, but later studies do not find evidence of large muscle attachments on the frill bones.\n\nTriceratops were long thought to have used their horns and frills in combat with predators such as Tyrannosaurus, the idea being discussed first by Charles H. Sternberg in 1917 and 70 years later by Robert Bakker. There is evidence that Tyrannosaurus did have aggressive head-on encounters with Triceratops, based on partially healed tyrannosaur tooth marks on a Triceratops brow horn and squamosal; the bitten horn is also broken, with new bone growth after the break. Which animal was the aggressor is not known. Paleontologist Peter Dodson estimates that in a battle against a bull Triceratops, the Triceratops had the upper hand and would successfully defend itself by inflicting fatal wounds to the Tyrannosaurus using its sharp horns. Tyrannosaurus is also known to have fed on Triceratops, as shown by a heavily tooth-scored Triceratops ilium and sacrum.",

These corpora are based on Wikipedia, so more comparable than the others, and have already been used for the evaluation of several QA systems.\nWikiQA BIBREF6 comprises questions selected from the Bing search queries, where user click data give the questions and their corresponding Wikipedia articles. The abstracts of these articles are then extracted to create answer candidates. The assumption is made that if many queries lead to the same article, it must contain the answer context; however, this assumption fails for some occasions, which makes this dataset more challenging. Since the existence of answer contexts is not guaranteed in this task, it is called answer triggering instead of answer selection.\nSelQA BIBREF7 is a product of five annotation tasks through crowdsourcing. It consists of about 8K questions where a half of the questions are paraphrased from the other half, aiming to reduce contextual similarities between questions and answers. Each question is associated with a section in Wikipedia where the answer context is guaranteed, and also with five sections selected from the entire Wikipedia where the selection is made by the Lucene search engine. This second dataset does not assume the existence of the answer context, so can be used for the evaluation of answer triggering.\nSQuAD BIBREF12 presents 107K+ crowdsourced questions on 536 Wikipedia articles, where the answer contexts are guaranteed to exist within the provided paragraph. It contains annotation of answer phrases as well as the pointers to the sentences including the answer phrases; thus, it can be used for both answer extraction and selection. This corpus also provides human accuracy on those questions, setting up a reasonable upper bound for machines. To avoid overfitting, the evaluation set is not publicly available although system outputs can be evaluated by their provided script.\nInfoboxQA BIBREF13 gives 15K+ questions based on the infoboxes from 150 articles in Wikipedia. Each question is crowdsourced and associated with an infobox, where each line of the infobox is considered an answer candidate. This corpus emphasizes the gravity of infoboxes, which summary arguably the most commonly asked information about those articles. Although the nature of this corpus is different from the others, it can also be used to evaluate answer selection.\nSELQA (Jurczyk et al., 2016) is a product of five annotation tasks through crowdsourcing.",

Directly learning based on the resulting corpus may adapt the neural feature extraction into the biased annotations. In this work, we assume that individual workers have their own guidelines in mind after short training. For example, a perfect worker can annotate highly consistently with an expert, while common crowdsourcing workers may be confused and have different understandings on certain contexts. Based on the assumption, we make an adaption for the original adversarial neural network to our setting.\nOur adaption is very simple. Briefly speaking, the original adversarial learning adds an additional discriminator to classify the type of source inputs, for example, the domain category in the domain adaption setting, while we add a discriminator to classify the annotation workers. Solely the features from the input sentence is not enough for worker classification. The annotation result of the worker is also required. Thus the inputs of our discriminator are different. Here we exploit both the source sentences and the crowd-annotated NE labels as basic inputs for the worker discrimination.\nIn the following, we describe the proposed adversarial learning module, including both the submodels and the training method. As shown by the left part of Figure 1 , the submodel consists of four parts: (1) a common Bi-LSTM over input characters; (2) an additional Bi-LSTM to encode crowd-annotated NE label sequence; (3) a convolutional neural network (CNN) to extract features for worker discriminator; (4) output and prediction.\nAs shown by the left part of Figure 1, the submodel consists of four parts: (1) a common Bi-LSTM over input characters; (2) an additional Bi-LSTM to encode crowd-annotated NE label sequence; (3) a convolutional neural network (CNN) to extract features for worker discriminator; (4) output and prediction.",

TED is also multilingual in a sense that it includes numbers of talks which are commonly translated into many languages. In addition, we use a much larger corpus provided freely by WMT organizers when we evaluate the impact of our approach in a real machine translation campaign. It includes the paralled corpus extracted from the digital corpus of European Parliament (EPPS), the News Commentary (NC) and the web-crawled parallel data (CommonCrawl). While the number of sentences in popular TED corpora varies from 13 thousands to 17 thousands, the total number of sentences in those larger corpus is approximately 3 million sentences.\nNeural Machine Translation Setup. All experiments have been conducted using NMT framework Nematus, Following the work of Sennrich2016a, subword segmentation is handled in the prepocessing phase using Byte-Pair Encoding (BPE). Excepts stated clearly in some experiments, we set the number of BPE merging operations at 39500 on the joint of source and target data. When training all NMT systems, we take out the sentence pairs exceeding 50-word length and shuffle them inside every minibatch. Our short-list vocabularies contain 40,000 most frequent words while the others are considered as rare words and applied the subword translation. We use an 1024-cell GRU layer and 1000-dimensional embeddings with dropout at every layer with the probability of 0.2 in the embedding and hidden layers and 0.1 in the input and ourput layers. We trained our systems using gradient descent optimization with Adadelta BIBREF13 on minibatches of size 80 and the gradient is rescaled whenever its norm exceed 1.0. All the trainings last approximately seven days if the early-stopping condition could not be reached. At a certain time, an external evaluation script on BLEU BIBREF14 is conducted on a development set to decide the early-stopping condition. This evaluation script has also being used to choose the model archiving the best BLEU on the development set instead of the maximal loglikelihood between the translations and target sentences while training. In translation, the framework produces INLINEFORM0 -best candidates and we then use a beam search with the beam size of 12 to get the best translation.\nOur short-list vocabularies contain 40,000 most frequent words while the others are considered as rare words and applied the subword translation.

        "answer": "Three.",
        "evidence": "We compare our hierarchical model against three systems. For each of them, we report the results of the best performing models presented in each paper.\n$\\bullet $ Wiseman BIBREF10 is a standard encoder-decoder system with copy mechanism.\n$\\bullet $ Li BIBREF28 is a standard encoder-decoder with a delayed copy mechanism: text is first generated with placeholders, which are replaced by salient records extracted from the table by a pointer network.\n$\\bullet $ Puduppully-plan BIBREF12 acts in two steps: a first standard encoder-decoder generates a plan, i.e. a list of salient records from the table; a second standard encoder-decoder generates text from this plan.\n$\\bullet $ Puduppully-updt BIBREF13. It consists in a standard encoder-decoder, with an added module aimed at updating record representations during the generation process. At each decoding step, a gated recurrent network computes which records should be updated and what should be their new representation.\n\nWe test the importance of the input structure by training different variants of the proposed architecture:\n$\\bullet $ Flat, where we feed the input sequentially to the encoder, losing all notion of hierarchy. As a consequence, the model uses standard attention. This variant is closest to Wiseman, with the exception that we use a Transformer to encode the input sequence instead of an RNN.\n$\\bullet $ Hierarchical-kv is our full hierarchical model, with traditional hierarchical attention, i.e. where attention over records is computed on the full record encoding, as in equation (SECREF16).\n$\\bullet $ Hierarchical-k is our full hierarchical model, with key-guided hierarchical attention, i.e. where attention over records is computed only on the record key representations, as in equation (DISPLAY_FORM17).\nFrom a general point of view, we can see from Table TABREF25 that our scenarios obtain significantly higher results in terms of BLEU over all models; our best model Hierarchical-k reaching $17.5$ vs. $16.5$ against the best baseline. This means that our models learns to generate fluent sequences of words, close to the gold descriptions, adequately picking up on domain lingo. Qualitative metrics are either better or on par with baselines. We show in Figure FIGREF29 a text generated by our best model, which can be directly compared to the gold description in Figure FIGREF1. Generation is fluent and contains domain-specific expressions. As reflected in Table TABREF25, the number of correct mentions (in green) outweights the number of incorrect mentions (in red). Please note that, as in previous work BIBREF28, BIBREF12, BIBREF13, BIBREF10, generated texts still contain a number of incorrect facts, as well hallucinations (in blue): sentences that have no basis in the input data (e.g. “[...] he's now averaging 22 points [...].\"). While not the direct focus of our work, this highlights that any operation meant to enrich the semantics of structured data can also enrich the data with incorrect facts.\nSpecifically, regarding all baselines, we can outline the following statements.\n$\\bullet $ Our hierarchical models achieve significantly better scores on all metrics when compared to the flat architecture Wiseman, reinforcing the crucial role of structure in data semantics and saliency. The analysis of RG metrics shows that Wiseman seems to be the more naturalistic in terms of number of factual mentions (RG#) since it is the closest scenario to the gold value (16.83 vs. 17.31 for resp. Wiseman and Hierarchical-k). However, Wiseman achieves only $75.62$% of precision, effectively mentioning on average a total of $22.25$ records (wrong or accurate), where our model Hierarchical-k scores a precision of $89.46$%, leading to $23.66$ total mentions, just slightly above Wiseman.\n$\\bullet $ The comparison between the Flat scenario and Wiseman is particularly interesting. Indeed, these two models share the same intuition to flatten the data-structure. The only difference stands on the encoder mechanism: bi-LSTM vs. Transformer, for Wiseman and Flat respectively. Results shows that our Flat scenario obtains a significant higher BLEU score (16.7 vs. 14.5) and generates fluent descriptions with accurate mentions (RG-P%) that are also included in the gold descriptions (CS-R%). This suggests that introducing the Transformer architecture is promising way to implicitly account for data structure.\n$\\bullet $ Our hierarchical models outperform the two-step decoders of Li and Puduppully-plan on both BLEU and all qualitative metrics, showing that capturing structure in the encoding process is more effective that predicting a structure in the decoder (i.e., planning or templating). While our models sensibly outperform in precision at factual mentions, the baseline Puduppully-plan reaches $34.28$ mentions on average, showing that incorporating modules dedicated to entity extraction leads to over-focusing on entities; contrasting with our models that learn to generate more balanced descriptions.\n$\\bullet $ The comparison with Puduppully-updt shows that dynamically updating the encoding across the generation process can lead to better Content Ordering (CO) and RG-P%. However, this does not help with Content Selection (CS) since our best model Hierarchical-k obtains slightly better scores. Indeed, Puduppully-updt updates representations after each mention allowing to keep track of the mention history. This guides the ordering of mentions (CO metric), each step limiting more the number of candidate mentions (increasing RG-P%). In contrast, our model encodes saliency among records/entities more effectively (CS metric). We note that while our model encodes the data-structure once and for all, Puduppully-updt recomputes, via the updates, the encoding at each step and therefore significantly increases computation complexity. Combined with their RG-# score of $30.11$, we argue that our model is simpler, and obtains fluent description with accurate mentions in a more human-like fashion.\nWe would also like to draw attention to the number of parameters used by those architectures. We note that our scenarios relies on a lower number of parameters (14 millions) compared to all baselines (ranging from 23 to 45 millions). This outlines the effectiveness in the design of our model relying on a structure encoding, in contrast to other approach that try to learn the structure of data/descriptions from a linearized encoding.\n\nWe compare our hierarchical model against three systems.",

Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach.",

        "evidence": "In most other analyses and datasets, the idea of out-of-scope data is not considered, and instead the output classes are intended to cover all possible queries (e.g., TREC BIBREF7). Recent work by BIBREF8 considers a similar problem they call out-of-distribution detection. They use other datasets or classes excluded during training to form the out-of-distribution samples. This means that the out-of-scope samples are from a small set of coherent classes that differ substantially from the in-distribution samples. Similar experiments were conducted for evaluating unknown intent discovery models in BIBREF9. In contrast, our out-of-scope queries cover a broad range of phenomena and are similar in style and often similar in topic to in-scope queries, representing things a user might say given partial knowledge of the capabilities of a system.\nTable TABREF20 compares our dataset with other short-query intent classification datasets. The Snips BIBREF0 dataset and the dataset presented in BIBREF10 are the most similar to the in-scope part of our work, with the same type of conversational agent requests. Like our work, both of these datasets were bootstrapped using crowdsourcing. However, the Snips dataset has only a small number of intents and an enormous number of examples of each. Snips does present a low-data variation, with 70 training queries per intent, in which performance drops slightly. The dataset presented in BIBREF10 has a large number of intent classes, yet also contains a wide range of samples per intent class (ranging from 24 to 5,981 queries per intent, and so is not constrained in all cases).\nBIBREF11 created datasets with constrained training data, but with very few intents, presenting a very different type of challenge. We also include the TREC query classification datasets BIBREF7, which have a large set of labels, but they describe the desired response type (e.g., distance, city, abbreviation) rather than the action intents we consider. Moreover, TREC contains only questions and no commands. Crucially, none of the other datasets summarized in Table TABREF20 offer a feasible way to evaluate out-of-scope performance.\nThe Dialog State Tracking Challenge (DSTC) datasets are another related resource. Specifically, DSTC 1 BIBREF12, DSTC 2 BIBREF13, and DSTC 3 BIBREF14 contain “chatbot style\" queries, but the datasets are focused on state tracking. Moreover, most if not all queries in these datasets are in-scope. In contrast, the focus of our analysis is on both in- and out-of-scope queries that challenge a virtual assistant to determine whether it can provide an acceptable response.\nThe Snips (Coucke et al., 2018) dataset and the dataset presented in Liu et al.

        "evidence": "Word Sense Disambiguation (WSD) is an important problem in Natural Language Processing (NLP), both in its own right and as a stepping stone to other advanced tasks in the NLP pipeline, applications such as machine translation BIBREF0 and question answering BIBREF1 . WSD specifically deals with identifying the correct sense of a word, among a set of given candidate senses for that word, when it is presented in a brief narrative (surrounding text) which is generally referred to as context. Consider the ambiguous word `cold'. In the sentence “He started to give me a cold shoulder after that experiment”, the possible senses for cold can be cold temperature (S1), a cold sensation (S2), common cold (S3), or a negative emotional reaction (S4). Therefore, the ambiguous word cold is specified along with the sense set {S1, S2, S3, S4} and our goal is to identify the correct sense S4 (as the closest meaning) for this specific occurrence of cold after considering - the semantic and the syntactic information of - its context.\nIn this effort, we develop our supervised WSD model that leverages a Bidirectional Long Short-Term Memory (BLSTM) network. This network works with neural sense vectors (i.e. sense embeddings), which are learned during model training, and employs neural word vectors (i.e. word embeddings), which are learned through an unsupervised deep learning approach called GloVe (Global Vectors for word representation) BIBREF2 for the context words. By evaluating our one-model-fits-all WSD network over the public gold standard dataset of SensEval-3 BIBREF3 , we demonstrate that the accuracy of our model in terms of F-measure is comparable with the state-of-the-art WSD algorithms'.\nWe outline the organization of the rest of the paper as follows. In Section 2, we briefly explore earlier efforts in WSD and discuss recent approaches that incorporate deep neural networks and word embeddings. Our main model that employs BLSTM with the sense and word embeddings is detailed in Section 3. We then present our experiments and results in Section 4 supported by a discussion on how to avoid some drawbacks of the current model in order to achieve higher accuracies and demand less number of training data which is desirable. Finally, in Section 5, we conclude with some future research directions for the construction of sense embeddings as well as applications of such model in other domains such as biomedicine.\nThis network works with neural sense vectors (i.e. sense embeddings), which are learned during model training, and employs neural word vectors (i.e. word embeddings), which are learned through an unsupervised deep learning approach called GloVe (Global Vectors for word representation) for the context words.",

        "answer": "Benchmark longevity and robustness issues.",
        "evidence": "Progress in AI has been driven by, among other things, the development of challenging large-scale benchmarks like ImageNet BIBREF0 in computer vision, and SNLI BIBREF1, SQuAD BIBREF2, and others in natural language processing (NLP). Recently, for natural language understanding (NLU) in particular, the focus has shifted to combined benchmarks like SentEval BIBREF3 and GLUE BIBREF4, which track model performance on multiple tasks and provide a unified platform for analysis.\nWith the rapid pace of advancement in AI, however, NLU benchmarks struggle to keep up with model improvement. Whereas it took around 15 years to achieve “near-human performance” on MNIST BIBREF5, BIBREF6, BIBREF7 and approximately 7 years to surpass humans on ImageNet BIBREF8, BIBREF0, BIBREF9, the GLUE benchmark did not last as long as we would have hoped after the advent of BERT BIBREF10, and rapidly had to be extended into SuperGLUE BIBREF11. This raises an important question: Can we collect a large benchmark dataset that can last longer?\nThe speed with which benchmarks become obsolete raises another important question: are current NLU models genuinely as good as their high performance on benchmarks suggests? A growing body of evidence shows that state-of-the-art models learn to exploit spurious statistical patterns in datasets BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17, instead of learning meaning in the flexible and generalizable way that humans do. Given this, human annotators—be they seasoned NLP researchers or non-experts—might easily be able to construct examples that expose model brittleness.\nWe propose an iterative, adversarial human-and-model-in-the-loop solution for NLU dataset collection that addresses both benchmark longevity and robustness issues. In the first stage, human annotators devise examples that our current best models cannot determine the correct label for. These resulting hard examples—which should expose additional model weaknesses—can be added to the training set and used to train a stronger model. We then subject the strengthened model to human interference and collect more weaknesses over several rounds. After each round, we both train a new model, and set aside a new test set. The process can be iteratively repeated in a never-ending learning BIBREF18 setting, with the model getting stronger and the test set getting harder in each new round.This process yields a “moving post” dynamic target for NLU systems, rather than a static benchmark that will eventually saturate.\nOur approach draws inspiration from recent efforts that gamify collaborative training of machine learning agents over multiple rounds BIBREF19 and pit “builders” against “breakers” to learn better models BIBREF20. Recently, Dinan2019build showed that a similar approach can be used to make dialogue safety classifiers more robust. Here, we focus on natural language inference (NLI), arguably the most canonical task in NLU. We collected three rounds of data, and call our new dataset Adversarial NLI (ANLI).\nOur contributions are as follows: 1) We introduce a novel human-and-model-in-the-loop dataset, currently consisting of three rounds that progressively increase in difficulty and complexity, that includes annotator-provided explanations. 2) We show that training models on this new dataset leads to state-of-the-art performance on a variety of popular NLI benchmarks. 3) We provide a detailed analysis of the collected data that sheds light on the shortcomings of current models, categorizes the data by inference type to examine weaknesses, and demonstrates good performance on NLI stress tests. The ANLI dataset is available at github.com/facebookresearch/anli/. A demo of the annotation procedure can be viewed at adversarialnli.com.\nWe propose an iterative, adversarial human-andmodel-in-the-loop solution for NLU dataset collection that addresses both benchmark longevity and robustness issues.",

        "answer": "First, I'm so sorry that you got the news that your child has leukemia. No child should have to live through cancer, and no parent should have to watch their child suffer such a serious illness. I recommend that you listen closely to your doctor's opinion on treatment. It usually does not hurt to get a second opinion if you feel you need one. Next, I recommend learning all that you can about pediatric leukemia. There are many good texts available and your hospital may even have some on hand. If you can find another parent within your network who has gone through pediatric leukemia with their child, it can be helpful to talk to someone who has been through the experience. Many people also find comfort in support groups on Facebook, or through a local \"Leukemia & Lymphoma Society\" chapter. It can be hard on caretakers of children with leukemia, so it can be a good idea to get plenty of rest, food and liquids while you are under stress. Finding a good therapist can also be helpful along the journey. I hope that you are able to find peace during this difficult time and that you have the resources you need.",

Top N terms were selected and added to our dictionary where N=100k for higher count emotions joy, sadness, anger, love and N=50k for thankfulness and fear and N=25k for surprise. Seven binary classifiers were trained for the seven emotions with a batch size of 250 and for 20 epochs with binary cross-entropy as the objective function and Adam optimizer.

        "evidence": "The female cone has two types of scale: the bract scales, and the seed scales (or ovuliferous scales), one subtended by each bract scale, derived from a highly modified branchlet. On the upper-side base of each seed scale are two ovules that develop into seeds after fertilization by pollen grains. The bract scales develop first, and are conspicuous at the time of pollination; the seed scales develop later to enclose and protect the seeds, with the bract scales often not growing further. The scales open temporarily to receive pollen, then close during fertilization and maturation, and then re-open again at maturity to allow the seed to escape. Maturation takes 6–8 months from pollination in most Pinaceae genera, but 12 months in cedars and 18–24 months (rarely more) in most pines. The cones open either by the seed scales flexing back when they dry out, or (in firs, cedars and golden larch) by the cones disintegrating with the seed scales falling off. The cones are conic, cylindrical or ovoid (egg-shaped), and small to very large, from 2–60 cm long and 1–20 cm broad.\n\nAfter ripening, the opening of non-serotinous pine cones is associated with their moisture content—cones are open when dry and closed when wet. This assures that the small, windborne seeds will be dispersed during relatively dry weather, and thus, the distance traveled from the parent tree will be enhanced. A pine cone will go through many cycles of opening and closing during its life span, even after seed dispersal is complete. This process occurs with older cones while attached to branches and even after the older cones have fallen to the forest floor. The condition of fallen pine cones is a crude indication of the forest floor's moisture content, which is an important indication of wildfire risk. Closed cones indicate damp conditions while open cones indicate the forest floor is dry.",
        "answer": "A pine cone consists of scales which protect seeds. The scales can open and close depending on conditions. The scales will open temporarily to receive pollen, then close again until the seeds mature. Once mature, the scales will open and close depending on their moisture content. Once the seeds are mature, the scales can open again to allow seeds to escape. When dry, the cones open allowing the small windborne seeds to disperse as widely as possible.

SRL is the problem of finding predicate-argument structure in a sentence, as illustrated below:\n INLINEFORM0 \nHere, the predicate WRITE has two arguments: `Mike' as A0 or the writer, and `a book' as A1 or the thing written. The labels A0 and A1 correspond to the PropBank annotations BIBREF0 .\nAs the need for SRL arises in different domains and languages, the existing manually annotated corpora become insufficient to build supervised systems. This has motivated work on unsupervised SRL BIBREF1 , BIBREF2 , BIBREF3 . Previous work has indicated that unsupervised systems could benefit from the word alignment information in parallel text in two or more languages BIBREF4 , BIBREF5 , BIBREF6 . For example, consider the German translation of sentence INLINEFORM0 :\n INLINEFORM0 \nIf sentences INLINEFORM0 and INLINEFORM1 have the word alignments: Mike-Mike, written-geschrieben, and book-Buch, the system might be able to predict A1 for Buch, even if there is insufficient information in the monolingual German data to learn this assignment. Thus, in languages where the resources are sparse or not good enough, or the distributions are not informative, SRL systems could be made more accurate by using parallel data with resource rich or more amenable languages.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages. The model consists of individual Bayesian models for each language BIBREF3 , and crosslingual latent variables to incorporate soft role agreement between aligned constituents. This latent variable approach has been demonstrated to increase the performance in a multilingual unsupervised part-of-speech tagging model based on HMMs BIBREF4 . We investigate the application of this approach to unsupervised SRL, presenting the performance improvements obtained in different settings involving labeled and unlabeled data, and analyzing the annotation effort required to obtain similar gains using labeled data.\nWe begin by briefly describing the unsupervised SRL pipeline and the monolingual semantic role induction model we use, and then describe our multilingual model.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages.",

        "answer": "n-grams that capture short-range linguistic patterns.",
        "evidence": "At a high level, as shown in Figure FIGREF4 , a product search engine works as follows: a customer issues a query, which is passed to a lexical matching engine (typically an inverted index BIBREF0 , BIBREF1 ) to retrieve all products that contain words in the query, producing a match set. The match set passes through stages of ranking, wherein top results from the previous stage are re-ranked before the most relevant items are finally displayed. It is imperative that the match set contain a relevant and diverse set of products that match the customer intent in order for the subsequent rankers to succeed. However, inverted index-based lexical matching falls short in several key aspects:\nIn this paper, we address the question: Given rich customer behavior data, can we train a deep learning model to retrieve matching products in response to a query? Intuitively, there is reason to believe that customer behavior logs contain semantic information; customers who are intent on purchasing a product circumvent the limitations of lexical matching by query reformulation or by deeper exploration of the search results. The challenge is the sheer magnitude of the data as well as the presence of noise, a challenge that modern deep learning techniques address very effectively.\nProduct search is different from web search as the queries tend to be shorter and the positive signals (purchases) are sparser than clicks. Models based on conversion rates or click-through-rates may incorrectly favor accessories (like a phone cover) over the main product (like a cell phone). This is further complicated by shoppers maintaining multiple intents during a single search session: a customer may be looking for a specific television model while also looking for accessories for this item at the lowest price and browsing additional products to qualify for free shipping. A product search engine should reduce the effort needed from a customer with a specific mission (narrow queries) while allowing shoppers to explore when they are looking for inspiration (broad queries).\nAs mentioned, product search typically operates in two stages: matching and ranking. Products that contain words in the query ( INLINEFORM0 ) are the primary candidates. Products that have prior behavioral associations (products bought or clicked after issuing a query INLINEFORM1 ) are also included in the candidate set. The ranking step takes these candidates and orders them using a machine-learned rank function to optimize for customer satisfaction and business metrics.\nWe present a neural network trained with large amounts of purchase and click signals to complement a lexical search engine in ad hoc product retrieval. Our first contribution is a loss function with a built-in threshold to differentiate between random negative, impressed but not purchased, and purchased items. Our second contribution is the empirical result that recommends average pooling in combination with INLINEFORM0 -grams that capture short-range linguistic patterns instead of more complex architectures. Third, we show the effectiveness of consistent token hashing in Siamese networks for zero-shot learning and handling out of vocabulary tokens.\nIn Section SECREF2 , we highlight related work. In Section SECREF3 , we describe our model architecture, loss functions, and tokenization techniques including our approach for unseen words. We then introduce the readers to the data and our input representations for queries and products in Section SECREF4 . Section SECREF5 presents the evaluation metrics and our results. We provide implementation details and optimizations to efficiently train the model with large amounts of data in Section SECREF6 . Finally, we conclude in Section SECREF7 with a discussion of future work.\nOur second contribution is the empirical result that recommends average pooling in combination with n-grams that capture short-range linguistic patterns instead of more complex architectures.",

Figure depicts the end-to-end training pipeline of the framework.

We implement and analyze four popular SSL methods -SimCLR, MoCo (V1 and V2), SimSiam, and BYOL. Variances in Siamese networks of these methods lead to differences in executions in these three operations 2 .\nLocal Training Firstly, each client k conducts self-supervised training on unlabeled data D k based on the same global model W o g downloaded from the server. Regardless of SSL methods, clients train with Siamese networks -an online network W o k and a target network W t k for E local epochs using cooresponding loss functions L. We classify these SSL methods with two major differences (Figure in Appendix A): 1) Only SimSiam and BYOL contain a predictor in the online network, so we denote their online network\n, where W k is the online encoder and W p k is the predictor; As for SimCLR and MoCo, W o k = W k . 2) SimCLR and SimSiam share identical weights between the online encoder and the target encoder, so W t k = W k . In contrast, MoCo and BYOL update the target encoder with EMA of the online encoder in every mini-batch:\n, where W g is the global encoder. Then, the server sent W o g to clients to update their online networks. The training iterates these three operations until it meets the stopping conditions.

        "answer": "Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN).",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results.",

        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nThird, we also apply semi-supervised learning, allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming.",

        "question": "What hypothesis do they want to study?",
        "answer": "The hypothesis that speaker characteristics embedded in x-vectors extracted from a single network, trained for speaker identification using general data, contain sufficient information to allow the detection of multiple diseases.",
        "evidence": "Recent advances in Machine Learning (ML) and, in particular, in Deep Neural Networks (DNN) have allowed the development of highly accurate predictive systems for numerous applications. Among others, health has received significant attention due to the potential of ML-based diagnostic, monitoring and therapeutic systems, which are fast (when compared to traditional diagnostic processes), easily distributed and cheap to implement (many such systems can be executed in mobile devices). Furthermore, these systems can incorporate biometric data to perform non-invasive diagnostics.\nAmong other data types, speech has been proposed as a valuable biomarker for the detection of a myriad of diseases, including: neurological conditions, such as Alzheimer’s BIBREF0, Parkinson’s disease (PD) BIBREF1 and Amyotrophic Lateral Sclerosis BIBREF2; mood disorders, such as depression, anxiety BIBREF3 and bipolar disorder BIBREF4; respiratory diseases, such as obstructive sleep apnea (OSA) BIBREF5. However, temporal and financial constraints, lack of awareness in the medical community, ethical issues and patient-privacy laws make the acquisition of medical data one of the greatest obstacles to the development of health-related speech-based classifiers, particularly for deep learning models. For this reason, most systems rely on knowledge-based (KB) features, carefully designed and selected to model disease symptoms, in combination with simple machine learning models (e.g. Linear classifiers, Support Vector Machines). KB features may not encompass subtler symptoms of the disease, nor be general enough to cover varying levels of severity of the disease. To overcome this limitation, some works have instead focused on speaker representation models, such as Gaussian Supervectors and i-vectors. For instance, Garcia et al. BIBREF1 proposed the use of i-vectors for PD classification and Laaridh et al. BIBREF6 applied the i-vector paradigm to the automatic prediction of several dysarthric speech evaluation metrics like intelligibility, severity, and articulation impairment. The intuition behind the use of these representations is the fact that these algorithms model speaker variability, which should include disease symptoms BIBREF1.\nProposed by Snyder et al., x-vectors are discriminative deep neural network-based speaker embeddings, that have outperformed i-vectors in tasks such as speaker and language recognition BIBREF7, BIBREF8, BIBREF9. Even though it may not be evident that discriminative data representations are suitable for disease detection when trained with general datasets (that do not necessarily include diseased patients), recent works have shown otherwise. X-vectors have been successfully applied to paralinguistic tasks such as emotion recognition BIBREF10, age and gender classification BIBREF11, the detection of obstructive sleep apnea BIBREF12 and as a complement to the detection of Alzheimer's Disease BIBREF0. Following this line of research, in this work we study the hypothesis that speaker characteristics embedded in x-vectors extracted from a single network, trained for speaker identification using general data, contain sufficient information to allow the detection of multiple diseases. Moreover, we aim to assess if this information is kept even when language mismatch is present, as has already been shown to be true for speaker recognition BIBREF8. In particular, we use the x-vector model as a feature extractor, to train Support Vector Machines for the detection of two speech-affecting diseases: Parkinson's disease (PD) and obstructive sleep apnea (OSA).\nPD is the second most common neurodegenerative disorder of mid-to-late life after Alzheimer’s disease BIBREF13, affecting 1% of people over the age of 65. Common symptoms include bradykinesia (slowness or difficulty to perform movements), muscular rigidity, rest tremor, as well as postural and gait impairment. 89% of PD patients develop also speech disorders, typically hypokinetic dysarthria, which translates into symptoms such as reduced loudness, monoloudness, monopitch, hypotonicity, breathy and hoarse voice quality, and imprecise articulation BIBREF14BIBREF15.\nOSA is a sleep-concerned breathing disorder characterized by a complete stop or decrease of the airflow, despite continued or increased inspiratory efforts BIBREF16. This disorder has a prevalence that ranges from 9% to 38% through different populations BIBREF17, with higher incidence in male and elderly groups. OSA causes mood and personality changes, depression, cognitive impairment, excessive daytime sleepiness, thus reducing the patients' quality of life BIBREF18, BIBREF19. It is also associated with diabetes, hypertension and cardiovascular diseases BIBREF16, BIBREF20. Moreover, undiagnosed sleep apnea can have a serious economic impact, having had an estimated cost of $\\$150$ billion in the U.S, in 2015 BIBREF21. Considering the prevalence and serious nature of the two diseases described above, speech-based technology that tests for their existence has the potential to become a key tool for early detection, monitoring and prevention of these conditions BIBREF22.\nThe remainder of this document is organized as follows. Section SECREF2 presents the background concepts on speaker embeddings, and in particular on x-vectors. Section SECREF3 introduces the experimental setup: the corpora, the tasks, the KB features and the speaker embeddings employed. The results are presented and discussed in section SECREF4. Finally, section SECREF5 summarizes the main conclusions and suggests possible directions for future work.\nX-vectors have been successfully applied to paralinguistic tasks such as emotion recognition, age and gender classification, the detection of obstructive sleep apnea and as a complement to the detection of Alzheimer's Disease.

        "evidence": "The CIA has covertly hired Professor Jerry Hathaway at Pacific Technical University to develop the power source for \"Crossbow\": a laser weapon precise enough to commit illegal political assassinations from outer space. Hathaway uses his position to recruit brilliant students to do the work for him but, aside from his graduate student and toady Kent, does not tell them the reason for their research.\n\nHathaway's latest prospect is genius high school student Mitch Taylor. Despite his youth and inexperience, Hathaway makes Mitch the lead on the project due to his innovative and original ideas in the field of laser physics. Mitch is roomed with Chris Knight, another member of the team, a legend in the \"National Physics Club\" and one of Mitch's idols. Mitch's ideal of Chris is shattered, however, when Chris turns out to be more of a goof-off than a hard-working student. Meanwhile, Hathaway hopes Mitch will encourage Chris to straighten up his act and that their two exceptional minds can develop a proper power source.\n\nWith the deadline quickly approaching, Mitch feels the pressure to complete the project while Chris continues in his carefree attitude. After inviting Mitch to a pool party to blow off steam, Kent reports this to Hathaway, who lambasts Mitch. Mitch breaks down and tearfully calls his parents, telling them he wants to go home. Kent records the call without Mitch's knowledge and later plays the recording over the school's public address system, humiliating Mitch. As Mitch begins packing to leave, Chris explains about the pressures of school and burdens of being highly intelligent by relating the history of former Pacific Tech student Lazlo Hollyfeld. Lazlo cracked under the pressure and disappeared (actually now living in the university's tunnels beneath Chris and Mitch's closet). Chris, fearing the same could happen to him, learned to lighten up and begin enjoying life. Mitch acquiesces to stay and they exact revenge on Kent by disassembling his car and reassembling it in his dorm room.\n\nHathaway, angry about the still-incomplete project and Chris's attitude, informs Chris that he intends to fail him in his final course needed for graduation and will give a coveted after-graduation job, originally promised to Chris, to Kent instead, as well as take steps to ensure Chris will never find work in the field of laser physics. Chris is disheartened and Mitch must use Chris's same argument to convince him to stay. The two commit themselves to finishing the 5 megawatt laser and making sure Chris passes Hathaway's final exam.\n\nKent sabotages their latest, nearly-successful apparatus. Though Chris knows Kent destroyed the laser, he can do nothing about it and is left to brood over the injustice; this inspires him to come up with a whole new system. The new solution works flawlessly, impressing Hathaway; he congratulates Chris and assures him that he will graduate. Chris and Mitch leave and celebrate, but Lazlo arrives to tell them his suspicions regarding the possible uses of such a laser. Realizing he is right, they return to the lab, but all the laser equipment has already been removed by Hathaway.\n\nThey surreptitiously implant a radio transmitter in Kent's mouth and use it convince him he is speaking to Jesus. Kent divulges the location of the Air Force base where the equipment has been installed on a B-1 bomber. Chris and Mitch sneak onto the airbase and reprogram the coordinates of the target before going to Hathaway's home to set up a small prism. They gather outside Hathaway's home to watch as another school professor and a Congressman arrive, having been told of the test. Kent arrives and, though he was told by Jesus to remain outside, he goes inside. The laser test begins, with the new target being Hathaway's house. A very large bag of popcorn (Hathaway detests popcorn) is heated by the laser refracted by the prism, filling the house entirely and causing it to burst at the seams, with Kent riding a popcorn wave through the front door. Lazlo arrives in an RV—which he has won using mathematics in a blind sweepstakes contest—to tell them he is leaving. Later, Hathaway arrives to see what has become of his house.",

        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nThere are three key issues that make learning this mapping non-trivial.

        "evidence": "Medical search engines are an essential component for many online medical applications, such as online diagnosis systems and medical document databases. A typical online diagnosis system, for instance, relies on a medical search engine. The search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem. One challenge medical search engines face is the segmentation of individual clinical entities. When a user query consists of multiple clinical entities, a search engine would often fail to recognize them as separate entities. For example, the user query “fever joint pain weight loss headache” contains four separate clinical entities: “fever”, “joint pain”, “weight loss”, and “headache”. But when the search engine does not recognize them as separate entities and proceeds to retrieve results for each word in the query, it may find \"pain\" in body locations other than \"joint pain\", or it may miss \"headache\" altogether, for example. Some search engines allow the users to enter a single clinical concept by selecting from an auto-completion pick list. But this could also result in retrieving inaccurate or partial results and lead to poor user experience.\nWe want to improve the medical search engine so that it can accurately retrieve all the relevant clinical concepts mentioned in a user query, where relevant clinical concepts are defined with respect to the terminologies the search engine uses. The problem of extracting clinical concept mentions from a user query can be seen as a variant of the Concept Extraction (CE) task in the frequently-cited NLP challenges in healthcare, such as 2010 i2b2/VA BIBREF0 and 2013 ShARe/CLEF Task 1 BIBREF1. Both CE tasks in 2010 i2b2/VA and 2013 ShARe/CLEF Task 1 ask the participants to design an algorithm to tag a set of predefined entities of interest in clinical notes. These entity tagging tasks are also known as clinical Named Entity Recognition (NER). For example, the CE task in 2010 i2b2/VA defines three types of entities: “problem”, “treatment”, and “test”. The CE task in 2013 ShARe/CLEF defines various types of disorder such as “injury or poisoning”, \"disease or syndrome”, etc. In addition to tagging, the CE task in 2013 ShARe/CLEF has an encoding component which requires selecting one and only one Concept Unique Identifier (CUI) from Systematized Nomenclature Of Medicine Clinical Terms (SNOMED-CT) for each disorder entity tagged. Our problem, similar to the CE task in 2013 ShARe/CLEF, also contains two sub-problems: tagging mentions of entities of interest (entity tagging), and selecting appropriate terms from a glossary to match the mentions (term matching). However, several major differences exist. First, compared to clinical notes, the user queries are much shorter, less technical, and often less coherent. Second, instead of encoding, we are dealing with term matching where we rank a few best terms that match an entity, instead of selecting only one. This is because the users who type the queries may not have a clear idea about what they are looking for, or could be laymen who know little terminology, it may be more helpful to provide a set of likely results and let the users choose. Third, the types of entities are different. Each medical search engine may have its own types of entities to tag. There is also one minor difference in the tagging scheme between our problem and the CE task in 2013 ShARe/CLEF - We limit our scope to dealing with entities of consecutive words and not disjoint entities . We use only Beginning, Inside, Outside (BIO) tags. Given the differences listed above, we need to customize a framework consisting of an entity tagging and term matching component for our CE problem.\nWe want to improve the medical search engine so that it can accurately retrieve all the relevant clinical concepts mentioned in a user query, where relevant clinical concepts are defined with respect to the terminologies the search engine uses.",

CNNs use a mathematical operation called convolution in place of general matrix multiplication in at least one of their layers. They are specifically designed to process pixel data and are used in image recognition and processing. They have applications in image and video recognition, recommender systems, image classification, image segmentation, medical image analysis, natural language processing, brain–computer interfaces, and financial time series.\n\nCNNs are also known as Shift Invariant or Space Invariant Artificial Neural Networks (SIANN), based on the shared-weight architecture of the convolution kernels or filters that slide along input features and provide translation-equivariant responses known as feature maps. Counter-intuitively, most convolutional neural networks are not invariant to translation, due to the downsampling operation they apply to the input.\n\nCNNs are regularized versions of multilayer perceptrons. Multilayer perceptrons are usually fully connected networks, that is, each neuron in one layer is connected to all neurons in the next layer. The \"full connectivity\" of these networks make them prone to overfitting data. Typical ways of regularization, or preventing overfitting, include: penalizing parameters during training (such as weight decay) or trimming connectivity (skipped connections, dropout, etc.) Developing robust datasets also increases the probability that CNNs will learn the generalized principles that characterize a given dataset rather than the biases of a poorly-populated set.",

In § SECREF47 we also present results on the data released as part of the WebNLG challenge.\nWe developed several models of varying quality for generating text from the tables in WikiBio. This gives us a diverse set of outputs to evaluate the automatic metrics on. Table TABREF32 lists the models along with their hyperparameter settings and their scores from the human evaluation (§ SECREF33 ). Our focus is primarily on neural sequence-to-sequence methods since these are most widely used, but we also include a template-based baseline. All neural models were trained on the WikiBio training set. Training details and sample outputs are included in Appendices SECREF56 & SECREF57 .\nWe divide these models into two categories and measure correlation separately for both the categories. The first category, WikiBio-Systems, includes one model each from the four families listed in Table TABREF32 . This category tests whether a metric can be used to compare different model families with a large variation in the quality of their outputs. The second category, WikiBio-Hyperparams, includes 13 different hyperparameter settings of PG-Net BIBREF19 , which was the best performing system overall. 9 of these were obtained by varying the beam size and length normalization penalty of the decoder network BIBREF23 , and the remaining 4 were obtained by re-scoring beams of size 8 with the information extraction model described in § SECREF4 . All the models in this category produce high quality fluent texts, and differ primarily on the quantity and accuracy of the information they express.

        "evidence": "With the massive increase in social interactions on online social networks, there has also been an increase of hateful activities that exploit such infrastructure. On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs). As baselines, we compare with feature spaces comprising of char n-grams BIBREF0 , TF-IDF vectors, and Bag of Words vectors (BoWV).\nMain contributions of our paper are as follows: (1) We investigate the application of deep learning methods for the task of hate speech detection. (2) We explore various tweet semantic embeddings like char n-grams, word Term Frequency-Inverse Document Frequency (TF-IDF) values, Bag of Words Vectors (BoWV) over Global Vectors for Word Representation (GloVe), and task-specific embeddings learned using FastText, CNNs and LSTMs. (3) Our methods beat state-of-the-art methods by a large margin ( INLINEFORM0 18 F1 points better).\nTo the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.",

He theorizes that people tend to naturally give love in the way that they prefer to receive love, and better communication between couples can be accomplished when one can demonstrate caring to the other person in the love language the recipient understands.\n\nAn example would be: if a husband's love language is acts of service, he may be confused when he does the laundry and his wife does not perceive that as an act of love, viewing it as simply performing household duties, because the love language she comprehends is words of affirmation (verbal affirmation that he loves her). She may try to use what she values, words of affirmation, to express her love to him, which he would not value as much as she does.

Hence, we could not train our model for a large number of epochs - it may be another cause of the low performance.\nWe want to show that translation terms generated by our multi-task transformer are roughly equally likely to be seen in the Europarl corpus (TC) or the CLEF corpus (RC). Given a translation term INLINEFORM0 , we compute the ratio of the probability of seeing INLINEFORM1 in TC and RC, INLINEFORM2 . Here, INLINEFORM3 and INLINEFORM4 is calculated similarly. Given a query INLINEFORM5 and its translation INLINEFORM6 provided by model INLINEFORM7 , we calculate the balance of INLINEFORM8 , INLINEFORM9 . If INLINEFORM10 is close to 1, the translation terms are as likely in TC as in RC. Figure FIGREF15 shows the balance values for transformer and our model for a random sample of 20 queries from the validation set of Italian queries, respectively. Figure FIGREF16 shows the balance values for transformer and our model for a random sample of 20 queries from the test set of Italian queries, respectively. It is evident that our model achieves better balance compared to baseline transformer, except for a very few cases.\nGiven a query INLINEFORM0 , consider INLINEFORM1 as the set of terms from human translation of INLINEFORM2 and INLINEFORM3 as the set of translation terms generated by model INLINEFORM4 . We define INLINEFORM5 and INLINEFORM6 as precision and recall of INLINEFORM7 for model INLINEFORM8 . In Table TABREF19 , we report average precision and recall for both transformer and our model across our train and validation query set over two language pairs. Our model generates precise translation, i.e. it avoids terms that might be useless or even harmful for retrieval. Generally, from our observation, avoided terms are highly likely terms from TC and they are generated because of translation model overfitting. Our model achieves a regularization effect through an auxiliary task. This confirms results from existing multi-tasking literature BIBREF15 .\nTo explore translation quality, consider pair of sample translations provided by two models. For example, against an Italian query, medaglia oro super vinse medaglia oro super olimpiadi invernali lillehammer, translated term set from our model is {gold, coin, super, free, harmonising, won, winter, olympics}, while transformer output is {olympic, gold, one, coin, super, years, won, parliament, also, two, winter}. Term set from human translation is: {super, gold, medal, won, lillehammer, olypmic, winter, games}. Transformer comes up with terms like parliament, also, two and years that never appears in human translation. We found that these terms are very likely in Europarl and rare in CLEF. Our model also generates terms such as harmonising, free, olympics that not generated by transformer. However, we found that these terms are equally likely in Europarl and CLEF.\nTo explore translation quality, consider pair of sample translations provided by two models.",

The double cutaway, elongated horns, and heavily contoured back were all designed for better balance and comfort to play while standing up and slung off the shoulder with a strap. The three-pickup design offered players increased versatility and choice in tone quality over earlier one- and two-pickup electric guitars, and a responsive and simplified vibrato arm integrated into the bridge plate, which marked a significant design improvement over other vibrato systems, such as those manufactured by Bigsby.

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nOur datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab.",

        "evidence": "Recently, with the emergence of neural seq2seq models, abstractive summarization methods have seen great performance strides BIBREF0, BIBREF1, BIBREF2. However, complex neural summarization models with thousands of parameters usually require a large amount of training data. In fact, much of the neural summarization work has been trained and tested in news domains where numerous large datasets exist. For example, the CNN/DailyMail (CNN/DM) BIBREF3, BIBREF4 and New York Times (NYT) datasets are in the magnitude of 300k and 700k documents, respectively. In contrast, in other domains such as student reflections, summarization datasets are only in the magnitude of tens or hundreds of documents (e.g., BIBREF5). We hypothesize that training complex neural abstractive summarization models in such domains will not yield good performing models, and we will indeed later show that this is the case for student reflections.\nTo improve performance in low resource domains, we explore three directions. First, we explore domain transfer for abstractive summarization. While domain transfer is not new, compared to prior summarization studies BIBREF6, BIBREF7, our training (news) and tuning (student reflection) domains are quite dissimilar, and the in-domain data is small. Second, we propose a template-based synthesis method to create synthesized summaries, then explore the effect of enriching training data for abstractive summarization using the proposed model compared to a synthesis baseline. Lastly, we combine both directions. Evaluations of neural abstractive summarization method across four student reflection corpora show the utility of all three methods.\nSecond, we propose a template-based synthesis method to create synthesized summaries, then explore the effect of enriching training data for abstractive summarization using the proposed model compared to a synthesis baseline.",

GANs have shown to be successful in image generation tasks BIBREF17 and recently, some progress has been observed in text generation BIBREF13, BIBREF12, BIBREF15. Our generator is a language model trained using backpropagation through time BIBREF18. During the pre-training phase we optimize for MLE and during the GAN training phase, we optimize on the creativity reward from the discriminator. The discriminator's encoder has the same architecture as the generator encoder module with the addition of a pooled decoder layer. The decoder contains 3 $[Dense Batch Normalization,ReLU]$ blocks and an addtional $Sigmoid$ layer. The discriminator decoder takes the hidden state at the last time step of a sequence concatenated with both the max-pooled and mean-pooled representation of the hidden states BIBREF19 and outputs a number in the range $[0,1]$. The difficulty of using GANs in text generation comes from the discrete nature of text, making the model non-differentiable hence, we update parameters for the generator model with policy gradients as described in Yu BIBREF15.\nWe utilize AWD-LSTM BIBREF20 and TransformerXL BIBREF21 based language models. For model hyperparameters please to refer to Supplementary Section Table TABREF5. We use Adam optimizer BIBREF22 with $\\beta 1= 0.7$ and $\\beta 2= 0.8$ similar to BIBREF19 and use a batch size of 50. Other practices for LM training were the same as BIBREF21 and BIBREF20 for Transformer-XL and AWD-LSTM respectively. We refer to our proposed GAN as Creative-GAN and compare it to a baseline (a language model equivalent to our pre-trained generator) and a GumbelGAN model BIBREF14 across all proposed datasets. We use three creative English datasets with distinct linguistic characteristics: (1) A corpus of 740 classical and contemporary English poems, (2) a corpus of 14950 metaphor sentences retrieved from a metaphor database website and (3) a corpus of 1500 song lyrics ranging across genres. The mix of linguistic styles within this corpus offers the potential for interesting variation during the generation phase. We use the same pre-processing as in earlier work BIBREF19, BIBREF23. We reserve 10% of our data for test set and another 10% for our validation set.\nWe first pre-train our generator on the Gutenberg dataset BIBREF24 for 20 epochs and then fine-tune BIBREF19 them to our target datasets with a language modeling objective. The discriminator's encoder is initialized to the same weights as our fine-tuned language model. Once we have our fine-tuned encoders for each target dataset, we train in an adversarial manner. The discriminator objective here is to score the quality of the creative text. The discriminator is trained for 3 iterations for every iteration of the generator, a practice seen in previous work BIBREF25. Creative-GAN relies on using the reward from the discriminator BIBREF12, BIBREF15 for backpropagation. We follow a similar training procedure for GumbelGAN. Outputs are generated through sampling over a multinomial distribution for all methods, instead of $argmax$ on the log-likelihood probabilities, as sampling has shown to produce better output quality BIBREF4. Please refer to Supplementary Section Table TABREF6 for training parameters of each dataset and Table TABREF5 for hyperparameters of each encoder. We pick these values after experimentation with our validation set.

        "evidence": "Natural language generation and document classification have been widely conducted using neural sequence models based on the encoder–decoder architecture. The underlying technique relies on the production of a context vector as the document representation, to estimate both tokens in natural language generation and labels in classification tasks. By combining recurrent neural networks with attention BIBREF0, the model is able to learn contextualized representations of words at the sentence level. However, higher-level concepts, such as discourse structure beyond the sentence, are hard for an RNN to learn, especially for longer documents. We hypothesize that NLP tasks such as summarization and document classification can be improved through the incorporation of discourse information.\nIn this paper, we propose to incorporate latent representations of discourse units into neural training. A discourse parser can provide information about the document structure as well as the relationships between discourse units. In a summarization scenario, for example, this information may help to remove redundant information or discourse disfluencies. In the case of document classification, the structure of the text can provide valuable hints about the document category. For instance, a scientific paper follows a particular discourse narrative pattern, different from a short story. Similarly, we may be able to predict the societal influence of a document such as a petition document, in part, from its discourse structure and coherence.\nSpecifically, discourse analysis aims to identify the organization of a text by segmenting sentences into units with relations. One popular representation is Rhetorical Structure Theory (RST) proposed by mann1988rhet, where the document is parsed into a hierarchical tree, where leaf nodes are the segmented units, known as Entity Discourse Units (EDUs), and non-terminal nodes define the relations.\nAs an example, in Figure FIGREF1 the two-sentence text has been annotated with discourse structure based on RST, in the form of 4 EDUs connected with discourse labels attr and elab. Arrows in the tree capture the nuclearity of relations, wherein a “satellite” points to its “nucleus”. The Nucleus unit is considered more prominent than the Satellite, indicating that the Satellite is a supporting sentence for the Nucleus. Nuclearity relationships between two EDUs can take the following three forms: Nucleus–Satellite, Satellite–Nucleus, and Nucleus–Nucleus. In this work, we use our reimplementation of the state of the art neural RST parser of BIBREF1, which is based on eighteen relations: purp, cont, attr, evid, comp, list, back, same, topic, mann, summ, cond, temp, eval, text, cause, prob, elab.\nThis research investigates the impact of discourse representations obtained from an RST parser on natural language generation and document classification. We primarily experiment with an abstractive summarization model in the form of a pointer–generator network BIBREF2, focusing on two factors: (1) whether summarization benefits from discourse parsing; and (2) how a pointer–generator network guides the summarization model when discourse information is provided. For document classification, we investigate the content-based popularity prediction of online petitions with a deep regression model BIBREF3. We argue that document structure is a key predictor of the societal influence (as measured by signatures to the petition) of a document such as a petition.\nOur primary contributions are as follows: (1) we are the first to incorporate a neural discourse parser in sequence training; (2) we empirically demonstrate that a latent representation of discourse structure enhances the summaries generated by an abstractive summarizer; and (3) we show that discourse structure is an essential factor in modelling the popularity of online petitions.\nWe primarily experiment with an abstractive summarization model in the form of a pointer–generator network, focusing on two factors: (1) whether summarization benefits from discourse parsing; and (2) how a pointer–generator network guides the summarization model when discourse information is provided.",

        "answer": "Comparable corpora of Russian and Ukrainian academic texts.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts.",

        "question": "How do the authors collect tweets for the Italian scenario?",
        "answer": "The authors first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites..",
        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31. Besides, when node B retweets node A we have an implicit confirmation that information from A appeared in B's Twitter feed BIBREF12. Quotes are simply a special case of retweets with comments.\nMentions usually include personal conversations as they allow someone to address a specific user or to refer to an individual in the third person; in the first case they are located at the beginning of a tweet and they are known as replies, otherwise they are put in the body of a tweet BIBREF20. The network of mentions is usually seen as a stronger version of interactions between Twitter users, compared to the traditional graph of follower/following relationships BIBREF32.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in (Vicario et al. 2019);",

Although useful, such categorization type sets are not much helpful when the classified articles are being used as the training data for Question-Answering systems, since the extracted knowledge-base does not provide detailed enough information to the model.\nOn the other hand, much larger categorization type sets such as Cyc-Taxonomy BIBREF5, Yago-Taxonomy BIBREF6, or Wikipedia's own taxonomy of categories BIBREF7 are not suitable for our task since the tags are not verifiable for annotators. In addition, taxonomies are not designed in a tree format, so some categories might have multiple super-categories and this would make the verification process much harder for the cases that the article is about multiple different topics.\nConsidering the mentioned problem requirements, we believe Extended Named Entities Hierarchy BIBREF8, containing 200 fine-grained categories tailored for Wikipedia articles, is the best fitting tag set.\nHigashinaka et al. higashinaka2012 were the first to use this extended tag set as the categorization output of the dumped Wikipedia pages while using a hand-extracted feature set for converting the pages into their model input vectors. Following their work, Suzuki et al. suzuki2016 modelled the links between different Wikipedia pages as an augmentation to the extracted input features to the classifier. They also proposed a more complex model for learning the mapping between the converted articles and the labels.\nAlthough providing useful insights, none of the works above have considered the multi-lingual nature of many Wikipedia articles. Hence, we decided to hire annotators and educate them on the Extended Named Entities (ENE) tag set to annotate each article with up to 6 different ENE classes, and exploit the Wikipedia language links in the annotated articles to create our multi-lingual Wikipedia classification dataset. Section 2 details our dataset creation process.\nWe then used the two models mentioned above, which are to the best of our knowledge the only works close enough to our task in hand, to benchmark our dataset. Section 3 provides more details about our feature selection method and the models. Section 4 presents our experimental setup and the classification results.\nWe then used the two models mentioned above, which are to the best of our knowledge the only works close enough to our task in hand, to benchmark our dataset.",

        "evidence": "Our political systems are unequal, and we suffer for it. Diversity in representation around decision-making tables is important for the health of our democratic institutions BIBREF0. One example of this inequity of representation is the gender disparity in politics: there are fewer women in politics than men, largely because women do not run for office at the same rate as men. This is because women face systemic barriers in political systems across the world BIBREF1. One of these barriers is online harassment BIBREF2, BIBREF3. Twitter is an important social media platform for politicians to share their visions and engage with their constituents. Women are disproportionately harassed on this platform because of their gender BIBREF4.\nTo raise awareness of online abuse and shift the discourse surrounding women in politics, we designed, built, and deployed ParityBOT: a Twitter bot that classifies hateful tweets directed at women in politics and then posts “positivitweets”. This paper focuses on how ParityBOT improves discourse in politics.\nPrevious work that addressed online harassment focused on collecting tweets directed at women engaged in politics and journalism and determining if they were problematic or abusive BIBREF5, BIBREF3, BIBREF6. Inspired by these projects, we go one step further and develop a tool that directly engages in the discourse on Twitter in political communities.

She began her career as a child actress in the early 1940s and was one of the most popular stars of classical Hollywood cinema in the 1950s. She then became the world's highest paid movie star in the 1960s, remaining a well-known public figure for the rest of her life. In 1999, the American Film Institute named her the seventh-greatest female screen legend of Classic Hollywood cinema.\n\nBorn in London to socially prominent American parents, Taylor moved with her family to Los Angeles in 1939. She made her acting debut with a minor role in the Universal Pictures film There's One Born Every Minute (1942), but the studio ended her contract after a year. She was then signed by Metro-Goldwyn-Mayer and became a popular teen star after appearing in National Velvet (1944). She transitioned to mature roles in the 1950s, when she starred in the comedy Father of the Bride (1950) and received critical acclaim for her performance in the drama A Place in the Sun (1951). She starred in \"Ivanhoe\" with Robert Taylor and Joan Fontaine. (1952). Despite being one of MGM's most bankable stars, Taylor wished to end her career in the early 1950s. She resented the studio's control and disliked many of the films to which she was assigned. She began receiving more enjoyable roles in the mid-1950s, beginning with the epic drama Giant (1956), and starred in several critically and commercially successful films in the following years. These included two film adaptations of plays by Tennessee Williams: Cat on a Hot Tin Roof (1958), and Suddenly, Last Summer (1959); Taylor won a Golden Globe for Best Actress for the latter.

        "question": "What emoticons or creative orthography are cited by the team in this paper?",
        "answer": "U$A, sh!t.",
        "evidence": "Preparing the data can be a complex and time-consuming process, often involving working with partially or wholly unstructured data. The pre-processing steps have a big impact on the operationalizations, subsequent analyses and reproducibility efforts BIBREF30 , and they are usually tightly linked to what we intend to measure. Unfortunately, these steps tend to be underreported, but documenting the pre-processing choices made is essential and is analogous to recording the decisions taken during the production of a scholarly edition or protocols in biomedical research. Data may also vary enormously in quality, depending on how it has been generated. Many historians, for example, work with text produced from an analogue original using Optical Character Recognition (OCR). Often, there will be limited information available regarding the accuracy of the OCR, and the degree of accuracy may even vary within a single corpus (e.g. where digitized text has been produced over a period of years, and the software has gradually improved). The first step, then, is to try to correct for common OCR errors. These will vary depending on the type of text, the date at which the `original' was produced, and the nature of the font and typesetting.\nOne step that almost everyone takes is to tokenize the original character sequence into the words and word-like units. Tokenization is a more subtle and more powerful process than people expect. It is often done using regular expressions or scripts that have been circulating within the NLP community. Tokenization heuristics, however, can be badly confused by emoticons, creative orthography (e.g., U$A, sh!t), and missing whitespace. Multi-word terms are also challenging. Treating them as a single unit can dramatically alter the patterns in text. Many words that are individually ambiguous have clear, unmistakable meanings as terms, like “black hole\" or “European Union\". However, deciding what constitutes a multi-word term is a difficult problem. In writing systems like Chinese, tokenization is a research problem in its own right.\nBeyond tokenization, common steps include lowercasing, removing punctuation, stemming (removing suffixes), lemmatization (converting inflections to a base lemma), and normalization, which has never been clearly defined, but often includes grouping abbreviations like “U.S.A.\" and “USA\", ordinals like “1st\" and “first\", and variant spellings like “noooooo\". The main goal of these steps is to improve the ratio of tokens (individual occurrences) to types (the distinct things in a corpus). Each step requires making additional assumptions about which distinctions are relevant: is “apple” different from “Apple”? Is “burnt” different from “burned”? Is “cool\" different from “coooool\"? Sometimes these steps can actively hide useful patterns, like social meaning BIBREF32 . Some of us therefore try do as little modification as possible.\nFrom a multilingual perspective, English and Chinese have an unusually simple inflectional system, and so it is statistically reasonable to treat each inflection as a unique word type. Romance languages have considerably more inflections than English; many indigenous North American languages have still more. For these languages, unseen data is far more likely to include previously-unseen inflections, and therefore, dealing with inflections is more important. On the other hand, the resources for handling inflections vary greatly by language, with European languages dominating the attention of the computational linguistics community thus far.\nWe sometimes also remove words that are not relevant to our goals, for example by calculating vocabulary frequencies. We construct a “stoplist” of words that we are not interested in. If we are looking for semantic themes we might remove function words like determiners and prepositions. If we are looking for author-specific styles, we might remove all words except function words. Some words are generally meaningful but too frequent to be useful within a specific collection. We sometimes also remove very infrequent words. Their occurrences are too low for robust patterns and removing them helps reducing the vocabulary size.\nThe choice of processing steps can be guided by theory or knowledge about the domain as well as experimental investigation. When we have labels, predictive accuracy of a model is a way to assess the effect of the processing steps. In unsupervised settings, it is more challenging to understand the effects of different steps. Inferences drawn from unsupervised settings can be sensitive to pre-processing choices BIBREF33 . Stemming has been found to provide little measurable benefits for topic modeling and can sometimes even be harmful BIBREF34 . All in all, this again highlights the need to document these steps.\nFinally, we can also mark up the data, e.g., by identifying entities (people, places, organizations, etc.) or parts of speech. Although many NLP tools are available for such tasks, they are often challenged by linguistic variation, such as orthographic variation in historical texts BIBREF35 and social media BIBREF32 . Moreover, the performance of NLP tools often drops when applying them outside the training domain, such as applying tools developed on newswire texts to texts written by younger authors BIBREF36 . Problems (e.g., disambiguation in named entity recognition) are sometimes resolved using considerable manual intervention. This combination of the automated and the manual, however, becomes more difficult as the scale of the data increases, and the `certainty' brought by the latter may have to be abandoned.\nTokenization heuristics, however, can be badly confused by emoticons, creative orthography (e.g., U$A, sh!t), and missing whitespace.",

        "question": "Is random oversampling performing better in model evaluation?",
        "answer": "Yes.It increases performance over base BERT by 4%.",
        "evidence": "The sentence level classification task is an imbalanced binary classification problem that we address using BERT BIBREF0. We use BERTBASE, uncased, which consists of 12 self-attention layers, and returns a 768-dimension vector that representation a sentence. So as to make use of BERT for sentence classification, we include a fully connected layer on top of the BERT self-attention layers, which classifies the sentence embedding provided by BERT into the two classes of interest (propaganda or non-propaganda).\nWe attempt to exploit various data augmentation techniques to address the problem of class imbalance. Table TABREF17 shows the results of our experiments for different data augmentation techniques when, after shuffling the training data, we train the model on 75% of the training data and test it on the remaining 25% of the training data and the development data.\nWe observe that BERT without augmentation consistently outperforms BERT with augmentation in the experiments when the model is trained on 75% of the training data and evaluated on the rest, i.e trained and evaluated on similar data, coming from the same distribution. This is consistent with observations by Wei et al. wei2019eda that contextual word embeddings do not gain from data augmentation. The fact that we shuffle the training data prior to splitting it into training and testing subsets could imply that the model is learning to associate topic words, such as `Mueller', as propaganda. However, when we perform model evaluation using the development set, which is dissimilar to the training, we observe that synonym insertion and word dropping techniques also do not bring performance gains, while random oversampling increases performance over base BERT by 4%. Synonym insertion provides results very similar to base BERT, while random deletion harms model performance producing lower scores. We believe that this could be attributed to the fact that synonym insertion and random word dropping involve the introduction of noise to the data, while oversampling does not. As we are working with natural language data, this type of noise can in fact change the meaning of the sentence. Oversampling on the other hand purely increases the importance of the minority class by repeating training on the unchanged instances.\nSo as to better understand the aspects of oversampling that contribute to these gains, we perform a class-wise performance analysis of BERT with/without oversampling. The results of these experiments (Table TABREF18) show that oversampling increases the overall recall while maintaining precision. This is achieved by significantly improving the recall of the minority class (propaganda) at the cost of the recall of the majority class.\nSo far we have been able to establish that a) the training and test sets are dissimilar, thus requiring us to generalise our model, b) oversampling provides a method of generalisation, and c) oversampling does this while maintaining recall on the minority (and thus more interesting) class.\nGiven this we explore alternative methods of increasing minority class recall without a significant drop in precision. One such method is cost-sensitive classification, which differs from random oversampling in that it provides a more continuous-valued and consistent method of weighting samples of imbalanced training data; for example, random oversampling will inevitably emphasise some training instances at the expense of others. We detail our methods of using cost-sensitive classification in the next section. Further experiments with oversampling might have provided insights into the relationships between these methods, which we leave for future exploration.\nHowever, when we perform model evaluation using the development set, which is dissimilar to the training, we observe that synonym insertion and word dropping techniques also do not bring performance gains, while random oversampling increases performance over base BERT by 4%.",

This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life.About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, CaMg(CO3)2. Magnesian limestone is an obsolete and poorly-defined term used variously for dolomite, for limestone containing significant dolomite (dolomitic limestone), or for any other limestone containing a significant percentage of magnesium. Most limestone was formed in shallow marine environments, such as continental shelves or platforms, though smaller amounts were formed in many other environments.

        "question": "It seems persistent samples that are newly rejuvenated (up to about 50K Langevin steps since rejuvenation, and possibly many more) cannot be approximate steady-state samples, is it correct?",
        "answer": "Your understanding is correct. Intuitively, current rejuvenation sources always generate samples very \"far\" from the steady-state, even if they look quite similar to steady-state samples. Steady-state convergence can only be achieved after a long burn-in process (empirically, at least 50K steps for our method. Other methods/MCMC samplers might require more).",
        "evidence": "Prior work has suggested that persistent learning is the most effective method for learning a valid EBM density. Furthermore, works that learn a valid density have avoided rejuvenation because the incorporation of newly rejuvenated samples into the persistent bank ensures that EBM updates will always include samples that are not at the steady-state. However, persistent learning without rejuvenation has shortcomings mentioned in Section 3. We present hypothesized conditions for learning a valid density that motivate the design of our MCMC initialization:\n• After a certain point in training, all samples used to update the EBM must be approximate steadystate samples of the current model p(x; θ). • Persistent samples that are newly rejuvenated (up to about 50K Langevin steps since rejuvenation, and possibly many more) cannot be approximate steady-state samples for any known rejuvenation sources, including data, generators, and noise. • Persistent samples that have undergone sufficiently many lifetime Langevin updates for a model whose weights are changing very slowly can be approximate steady-state samples.\nFigure: Visualization of our longrun initializatin procedure. Newly rejuvenated samples must remain the the burnin bank until they have approach the model steady-state, at which point they move to the update bank to be used for model gradients.\nBoth the second and third point are corroborated by prior work as well as our own observations. The third point means that persistent states updated with shortrun Langevin can eventually act as longrun Langevin samples if the optimizer learning rate is small, because the EBM samples in previous timesteps are essentially samples from the current EBM.\nLearning a valid density that includes rejuvenation while satisfying the conditions above requires separating the newly rejuvenated samples from samples that are used to update the EBM. This leads us to introduce two persistent image banks: one for newly rejuvenated samples, and one for samples that will be used to update the EBM. Samples in the newly rejuvenated bank that have been updated sufficiently many times will eventually replace samples from the bank used to update the EBM, at which point newly rejuvenated states will be added to the burn-in bank. Figure shows a visualization of the MCMC initialization method. As in Section 3, we will use a pre-trained generator to efficiently obtain high-quality rejuvenated samples so that the generation process is fully synthetic, although data samples could be used as well. Our goal is to preserve the sample quality for an arbitrary number of MCMC steps. We note that this is a sufficient but not necessary condition for learning a valid EBM density. Nonetheless, stable sampling is an important step towards rigorous probabilistic EBMs. Even with our improved initialization, we find that extremely longrun trajectories of 1 million or more MCMC steps still tend to oversaturate, although to a much lesser degree. To further stabilize the appearance of extremely longrun Langevin samples, we include prior energy terms in the model. Our longrun EBMs have the form\nwhere U (x; θ) is the model whose weights are updated, U 0 (x; θ 0 ) is a prior EBM with fixed weights θ 0 and σ is a parameter controlling the strength of a Gaussian prior. We used a prior EBM in a shortrun manner. The role of the prior EBM is to provide some stability but also to provide a tendency to oversaturate at longer trajectories so that the current EBM learns to correct oversaturation. The Gaussian prior is meant to discourage unbounded activations outside of the image hypercube. Further discussion is in Appendix H. We find that including both of these terms significantly improves the ability to learn quality synthesis over long trajectories.\nFurthermore, works that learn a valid density have avoided rejuvenation because the incorporation of newly rejuvenated samples into the persistent bank ensures that EBM updates will always include samples that are not at the steady-state.",

        "answer": "Nothing screams camping out in the wilderness like building a campfire.   The memories, conversations, scents, roasted marshmallows, and crackling of the wood are all part of the experience.   In order to build a strong campfire, you need to perform the following steps.\nStep 1.  Clear a perimeter that is roughly 12 feet in diameter.   Make sure you are in an open area, where tree limbs are not hanging over the campfire to avoid secondary fires.   Before you start the fire, get all of the necessary components such as dry kindle/twigs, larger sticks, and larger logs, paper, and lighter\nStep 2.   Build a small tepee shape with the dry kindle and dry small logs.    I would recommend adding paper with the kindle to assist in starting the fire.\nStep 3.  Stack larger sticks around the teepee structure in a square formation.   Build up multiple levels, so the square structue is higher than the teepee.   This will help the fire expand and spread to the surrounding structure.\nStep 4.  Light the paper in the teepee with a match or lighter, and watch the  dry kindle  start to catch.    At this early stage, you will most likely see smoke.   You may need to blow on the teepee structure lightly in order to add some oxygen to the fire and help it catch to the larger sticks square structure.\nStep 5.  Once the square structure begins to light, start to add larger logs diagonally across the structure.   The diagonal formation will fuel the fire, and expand upwards .\nStep 6.  Keep adding larger logs to maintain the fire.   With the prior kindle, sticks, and logs already hot, adding the new larger logs will burn quickly and self ignite.\nStep 7.   When you are done enjoying the fire, have a couple of buckets of water nearby to extinguish it.   Do not leave the campfire unattended as the hot coals and wind could cause a unintended spread.",

A major difficulty we had is in training the option transition model Po(xf|xs) and the marginalized Poμ(xf|xs).

This failure motivated our design decision of approximating pO(o|xs,xf) instead of Po. We will clarify this point in the revised manuscript.",
        "evidence": "As presented in this section, we conducted two series of experiments to analyze the property of IMTC. First, we qualitatively evaluated the diversity of options learned by IMTC with intrinsic rewards, without any extrinsic rewards. Second, we quantitatively test the reusability of learned options by). Also, we can see that the magnitude of intra-option policies tends larger with constant rewards. Right: Options learned by other methods. OC produces a dead option 3 that terminates everywhere and never-ending options 0 and 1. About intra-option policies, all methods successfully avoided learning the same policy, but they only have two directions.\ntask adaptation on a specific task. As a baseline of termination learning method, we compared our method with OC. OC is trained with VIC rewards during pre-training. We did not compare IMTC with TC because our TC implementation failed to learn options with relatively small termination regions as reported in the paper, and there is no official public code for TC 1 . During pre-training without extrinsic rewards, IMTC receives intrinsic rewards when the current option terminates. We compare three IMTC variants with different intrinsic rewards: (i) VIC, (ii) RVIC, and (iii) constant value (R IMTC = 0.01). Note that R IMTC = 0.01 is chosen from [0.1, 0.05, 0.01] based on the task adaptation results. We also compare IMTC with vanilla VIC and RVIC with fixed termination probabilities. We used ∀ x β o (x) = 0.1 since it performed the best in task adaptation experiments, while 0.05 was used in. Note that RVIC's objective I(X s ; O|x f ) is different from ours, while IMTC and VIC share almost the same objective. Thus, the use of VIC is more natural, and the combination with RVIC is tested to show the applicability of IMTC. Further details of our VIC and RVIC implementation are found in Appendix B. In order to check only the effect of the different methods for learning beta β o , the rest of the implementation is the same for all these methods. That is, OC, vanilla VIC, and vanilla RVIC are also based on PPO and advantage estimation methods in Section 4.2. In this section, we fix the number of options as |O| = 4 for all option-learning methods. We further investigated the effect of the number of options Appendix C, where we confirmed that |O| = 4 is sufficient for most domains. All environments that we used for experiments are implemented on the MuJoCo physics simulator. We further describe the details in Appendix C.\nOption Learning From Intrinsic Rewards We now qualitatively compare the options learned by IMTC with options of other methods. Learned options depend on the reward structure in the environment, which enables manually designing good reward functions for learning diverse options. Thus, we employed a reward-free RL setting where no reward is given to agents. Instead, each compared method uses some intrinsic rewards, as explained. We fix µ as µ(o|x) = 1 |O| in this experiment, since we assume that the future tasks are uniformly distributed. Intra-option policies are trained by PPO and independent GAE (8). We show network architectures and hyperparameters in Appendix C. We set the episode length to 1 × 10 4 , i.e., an agent is reset to its starting position after 1 × 10 4 steps. For all visualizations, we chose the best one from five independent runs with different random seeds.  We visualized learned options in PointReach environment shown in Figure. In this environment, an agent controls the ball initially placed at the center of the room. The state space consists of positions (x, y) and velocities (∆x, ∆y) of an agent, and the action space consists of acceralations ( ∆x ∆t , ∆y ∆t ). Figure shows the options learned in this environment after 4 × 10 6 steps. Each arrow represents the mean value of intra-option policies, and the heatmaps represent β o . In this experiment, we observed the effect of IMTC clearly, for both termination regions and intra-option policies. Interestingly, we don't see clear differences between options learned with VIC and RVIC rewards, while constant rewards tend to make options peaker. OC failed to learn meaningful termination regions: option 0 and 1 never terminate, and option 3 terminates almost everywhere. This result confirms that IMTC can certainly diversify options. Moreover, compared to vanilla VIC and RVIC, intra-option policies learned by IMTC with VIC or RVIC rewards are clearer, in terms of both the magnitude and directions of policies. We believe that this is because diversifying termination regions gives more biased samples to the option classifiers employed by VIC and RVIC. Figure Transferring skills via task adaptation Now we quantitatively test the reusability of learned options by task adaptation with specific reward functions. Specifically, we first trained agents with intrinsic rewards as per the previous section. Then we transferred agents to an environment with the same state and action space but with external rewards. We prepared multiple reward functions, which we call tasks, for each domain and evaluated the averaged performance over tasks. We compare IMTC with OC, vanilla VIC, vanilla RVIC, and PPO without pre-training. Also, we compare three variants of IMTC with different intrinsic rewards during pre-training. For a fair comparison, UGAE (9) and PPO are used for all options learning methods. Note that we found UGAE is very effective in this experiments, as we show the ablation study in Appendix C.6. For vanilla VIC and vanilla RVIC, termination probability is fixed to 0.1 through pre-training and task adaptation. -greedy based on Q O with = 0.1 is used as the option selection policy µ. We hypothesize that diverse options learned by IMTC can help quickly adapt to given tasks, supposing the diversity of tasks.\nFigure shows all domains used for task adaptation experiments. For simplicity, all tasks have goalbased sparse reward functions. I.e., an agent receives R t = 1.0 when it satisfies a goal condition, and otherwise the control cost −0.0001 is given. Red circles show possible goal locations for each task. When the agent fails to reach the goal after 1000 steps, it is reset to a starting position. PointReach, SwimmerReach, and AntReach are simple navigation tasks where an agent aim to just navigate itself to the goal. We also prepared tasks with object manipulation: in PointBilliard and AntBilliard an agent aims to kick the blue ball to the goal position, and in PointPush and AntPush, it has to push the block out of the way to the goal. We pre-traine options learning agents for 4 × 10 6 environmental steps and additionally trained them for 1 × 10 6 steps for each task. Figure shows learning curves and scatter plots drawn from five independent runs with  different random seeds per domain. 2 Here, we observed that IMTC with VIC or RVIC rewards performed the best or was compatible with baselines. IMTC with VIC performed better than OC with VIC except for AntRearch, which backs up the effectiveness of diversifying termination regions for learning reusable options. Also, IMTC with VIC and IMTC with RCIC respectively performed better in most of the tasks than VIC and RVIC with fixed termination probabilities. This result suggests that IMTC can boost the performance of option learning methods based on option classifiers, even when the objective is different as with RVIC. On the other hand, IMTC with constant rewards (R IMTC = 0.01) performed worse than IMTC with VIC or RVIC rewards, although it also learned diverse options as we show in Figure, suggesting the importance of adjusting rewards. We further analyzed the evolution of intrinsic rewards of VIC and RVIC in Appendix C.5. In addition, we can observe that IMTC's performance is especially better than other methods in relatively complex PointBilliard, AntBilliard, and AntPush, where object manipulation is required. Considering that manipulated balls and boxes move faster than agents in these domains, a choice of options can lead to larger differences in the future state. IMTC is suitable to these domains since it maximizes the diversity of the resulting states, while PPO struggles to learn. Contrary, IMTC's performance is close to other methods in Reach tasks, where the goal states are relatively close to the starting states in terms of euclidian distances.\nGridworld experiments and limitation of the method Although IMTC successfully learned diverse options in MuJoCo experiments, our analysis in Figure shows the possibility of learning options that are not interesting but have large MI. We further investigated this possibility by visualizing options in a classical four rooms gridworld in Appendix C.8. Interestingly, we observed that IMTC could fall into diverse but unmeaningful options in that environment. We believe that IMTC is often sufficient in a large environment where a randomly-initialized agent rarely gets the same trajectory. However, when the number of possible trajectories is small, diversifying the destinations could be insufficient. In such cases, it can be necessary to extend IMTC to diversify trajectories as done in.\nFirst, we qualitatively evaluated the diversity of options learned by IMTC with intrinsic rewards, without any extrinsic rewards.",

At the core of this issue is dehumanization, “the act of perceiving or treating people as less than human” BIBREF3, a process that heavily contributes to extreme intergroup bias BIBREF4. Language is central to studying this phenomenon; like other forms of bias BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, dehumanizing attitudes are expressed through subtle linguistic manipulations, even in carefully-edited texts. It is crucial to understand the use of such linguistic signals in mainstream media, as the media's representation of marginalized social groups has far-reaching implications for social acceptance, policy, and safety.\nWhile small-scale studies of dehumanization and media representation of marginalized communities provide valuable insights (e.g. BIBREF10), there exist no known large-scale analyses, likely due to difficulties in quantifying such a subjective and multidimensional psychological process. However, the ability to do large-scale analysis is crucial for understanding how dehumanizing attitudes have evolved over long periods of time. Furthermore, by being able to account for a greater amount of media discourse at once, large-scale techniques can provide a more complete view of the media environment to which the public is exposed.\nLinguistics and computer science offer valuable methods and insights on which such large-scale techniques might be developed for the study of dehumanization. By leveraging more information about the contexts in which marginalized groups are discussed, computational linguistic methods not only enable large-scale study of a complex psychological phenomenon, but can even reveal linguistic variations and changes that are not easily identifiable through qualitative analysis alone.\nIn this work, we develop a computational linguistic framework for analyzing dehumanizing language, with a focus on lexical signals of dehumanization. Social psychologists have identified numerous components of dehumanization, such as negative evaluations of a target group, denial of agency, moral disgust, and likening members of a target group to non-human entities such as vermin. Drawing upon this rich body of literature, we first identify clear linguistic analogs for these components and propose several computational techniques to measure these linguistic correlates. We then apply this general framework to explore changing representations of LGBTQ groups in the New York Times over the span of three decades. We additionally use this lens of dehumanization to investigate differences in social meaning between the denotationally-similar labels gay and homosexual.\nThis paper aims to bridge the gaps between computational modeling, sociolinguistics, and dehumanization research with implications for several disciplines. In addition to enabling large-scale studies of dehumanizing language and media representation of marginalized social groups, these techniques can be built into systems that seek to capture both conscious and unconscious biases in text. Furthermore, this work has implications for improving machines' abilities to automatically detect hate speech and abusive language online, which are typically underpinned by dehumanizing language. Finally, our case study demonstrates that such computational analyses of discussions about marginalized groups can provide unique insights into language variation and change within sensitive sociopolitical contexts, and help us understand how people (and institutions) use language to express their ideologies and attitudes towards certain social groups.\nAt the core of this issue is dehumanization, “the act of perceiving or treating people as less than human” (Haslam and Stratemeyer, 2016), a process that heavily contributes to extreme intergroup bias (Haslam,2006).",

QE can be performed on multiple granularities, including at word level, sentence level, or document level. In this paper, we focus on quality estimation at word level, which is framed as the task of performing binary classification of translated tokens, assigning “OK” or “BAD” labels.\nEarly work on this problem mainly focused on hand-crafted features with simple regression/classification models BIBREF4 , BIBREF5 . Recent papers have demonstrated that utilizing recurrent neural networks (RNN) can result in large gains in QE performance BIBREF6 . However, these approaches encode the context of the target word by merely concatenating its left and right context words, giving them limited ability to control the interaction between the local context and the target word.\nIn this paper, we propose a neural architecture, Context Encoding Quality Estimation (CEQE), for better encoding of context in word-level QE. Specifically, we leverage the power of both (1) convolution modules that automatically learn local patterns of surrounding words, and (2) hand-crafted features that allow the model to make more robust predictions in the face of a paucity of labeled data. Moreover, we further utilize stacked recurrent neural networks to capture the long-term dependencies and global context information from the whole sentence.\nWe tested our model on the official benchmark of the WMT18 word-level QE task.

        "evidence": "Our datasets can be used for various hate speech tasks. In this paper, we focus on generative hate speech intervention.\nThe goal of this task is to generate a response to hate speech that can mitigate its use during a conversation. The objective can be formulated as the following equation:\nwhere $c$ is the conversation, $r$ is the corresponding intervention response, and $D$ is the dataset. This task is closely related to the response generation and dialog generation, though several differences exist including dialog length, language cadence, and word imbalances. As a baseline, we chose the most common methods of these two tasks, such as Seq2Seq and VAE, to determine the initial feasibility of automatically generate intervention responses. More recent Reinforcement Learning method for dialog generation BIBREF21 can also be applied to this task with slight modification. Future work will explore more complex, and unique models.\nSimilar to BIBREF21, a generative model is considered as an agent. However, different from dialog generation, generative intervention does not have multiple turns of utterance, so the action of the agent is to select a token in the response. The state of the agent is given by the input posts and the previously generated tokens. Another result due to this difference is that the rewards with regard to ease of answering or information flow do not apply to this case, but the reward for semantic coherence does. Therefore, the reward of the agent is:\nwhere $rw(c,r)$ is the reward with regard to the conversation $c$ and its reference response $r$ in the dataset. $p(r|c)$ denotes the probability of generating response $r$ given the conversation $c$, and $p_{back}(c|r)$ denotes the backward probability of generating the conversation based on the response, which is parameterized by another generation network. The reward is a weighted combination of these two parts, which are observed after the agent finishing generating the response. We refer the readers to BIBREF21 for details.\nThe methods are evaluated using F-1 score, Precision-Recall (PR) AUC, and ReceiverOperating-Characteristic (ROC) AUC.",

        "question": "Is the chatbot always improved by adding the automatically extracted examples of either type?",
        "answer": "Yes, it is.",
        "evidence": "Training a dialogue agent to converse like a human requires extensive supervision. The most common approach is to train models to imitate humans in large corpora of crowdsourced or scraped conversations BIBREF0 . These fully-supervised conversations tend to be expensive to collect in sufficient quantity and/or occur in settings with significant differences from the deployment environment BIBREF1 . Instead, dialogue agents would ideally learn directly from dialogue, the conversations they participate in after deployment, which are usually abundant, task-specific, dynamic, and cheap. This corresponds to the way humans learn to converse—not merely observing others engaging in “expert-level” conversations, but instead actively adjusting and correcting our speech based on feedback woven throughout our own conversations BIBREF2 , BIBREF3 . Giving a dialogue agent this ability would enable it to continuously improve and adapt over its lifetime, rather than requiring additional annotation costs for each and every improvement.\nHowever, naively training a dialogue agent on its own conversations yields poor results. For example, training a model on its own output can simply reinforce its existing failure modes, and mistakes by the agent can lead to absurd conversations that no longer resemble the target domain BIBREF4 . To combat this, one approach is to allow the agent to request feedback during conversations BIBREF5 , BIBREF6 , e.g., when it believes it is about to make a mistake. This approach, however, falls victim to the Dunning-Kruger effect BIBREF7 , which in this case suggests that a bad model will also be bad at knowing when it is doing a bad job. Regardless of when feedback is requested, existing methods typically require accompanying scalar rewards or adherence to particular templates or structure to ensure that the feedback is usable by the model BIBREF8 , BIBREF9 , BIBREF10 . These requirements may be acceptable for paid annotators, but they impose unnatural workflows on unpaid conversation partners in a standard dialogue environment. Humans are able to request and provide feedback using only natural language; ideally, dialogue agents would be able to do the same.\nIn this work we propose the self-feeding chatbot, a dialogue agent with the ability to extract new examples from the conversations it participates in after deployment (Figure FIGREF1 ). Concretely, in addition to being trained on the primary Dialogue task, the agent is trained to predict its speaking partner's satisfaction with its responses. When the conversation seems to be going well, the user's responses (but not the bot's own utterances) become the targets in new training examples for the Dialogue task. When the agent believes it has made a mistake, it instead requests feedback on what it could have said instead. Predicting the feedback that will be provided in a given context becomes an auxiliary task (Feedback) on which the model is also trained. Importantly, these new examples improve the agent's dialogue abilities while using only natural responses from the user that do not require special structure, accompanying numerical feedback, or additional human intervention in order to be used.\nWith this approach, the conversations the chatbot participates in are sliced into two complementary datasets—one largely protected from the chatbot's mistakes (Dialogue examples), and one which directly addresses them (Feedback examples). We validate our approach on the PersonaChat BIBREF11 dialogue dataset, finding empirically that regardless of the number of available supervised examples, the dialogue ability of the chatbot is always improved by adding the automatically extracted examples of either type, and improves the most by adding both.\nThe main contributions of this work thus include the following:\nThe datasets and models described in this paper are available via the ParlAI platform BIBREF12 , along with training code. Hyperparameter values are included in Appendix SECREF13 .\nWe validate our approach on the PersonaChat dialogue dataset, finding empirically that regardless of the number of available supervised examples, the dialogue ability of the chatbot is always improved by adding the automatically extracted examples of either type, and improves the most by adding both.",

        "evidence": "Word embeddings are representations of words in numerical form, as vectors of typically several hundred dimensions. The vectors are used as an input to machine learning models; for complex language processing tasks these are typically deep neural networks. The embedding vectors are obtained from specialized learning tasks, based on neural networks, e.g., word2vec BIBREF0, GloVe BIBREF1, FastText BIBREF2, ELMo BIBREF3, and BERT BIBREF4. For training, the embeddings algorithms use large monolingual corpora that encode important information about word meaning as distances between vectors. In order to enable downstream machine learning on text understanding tasks, the embeddings shall preserve semantic relations between words, and this is true even across languages.\nProbably the best known word embeddings are produced by the word2vec method BIBREF5. The problem with word2vec embeddings is their failure to express polysemous words. During training of an embedding, all senses of a given word (e.g., paper as a material, as a newspaper, as a scientific work, and as an exam) contribute relevant information in proportion to their frequency in the training corpus. This causes the final vector to be placed somewhere in the weighted middle of all words' meanings. Consequently, rare meanings of words are poorly expressed with word2vec and the resulting vectors do not offer good semantic representations. For example, none of the 50 closest vectors of the word paper is related to science.\nThe idea of contextual embeddings is to generate a different vector for each context a word appears in and the context is typically defined sentence-wise. To a large extent, this solves the problems with word polysemy, i.e. the context of a sentence is typically enough to disambiguate different meanings of a word for humans and so it is for the learning algorithms. In this work, we describe high-quality models for contextual embeddings, called ELMo BIBREF3, precomputed for seven morphologically rich, less-resourced languages: Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish. ELMo is one of the most successful approaches to contextual word embeddings. At time of its creation, ELMo has been shown to outperform previous word embeddings BIBREF3 like word2vec and GloVe on many NLP tasks, e.g., question answering, named entity extraction, sentiment analysis, textual entailment, semantic role labeling, and coreference resolution.\nThis report is split into further five sections.

Twitch is operated by Twitch Interactive, a subsidiary of Amazon.com, Inc. It was introduced in June 2011 as a spin-off of the general-interest streaming platform Justin.tv. Content on the site can be viewed either live or via video on demand. The games shown on Twitch's current homepage are listed according to audience preference and include genres such as real-time strategy games (RTS), fighting games, racing games, and first-person shooters.\n\nThe popularity of Twitch eclipsed that of its general-interest counterpart. In October 2013, the website had 45 million unique viewers, and by February 2014, it was considered the fourth-largest source of peak Internet traffic in the United States. At the same time, Justin.tv's parent company was re-branded as Twitch Interactive to represent the shift in focus – Justin.tv was shut down in August 2014. That month, the service was acquired by Amazon for US$970 million, which later led to the introduction of synergies with the company's subscription service Amazon Prime. Twitch acquired Curse LLC in 2016, an operator of online video gaming communities and introduced means to purchase games through links on streams along with a program allowing streamers to receive commissions on the sales of games that they play.\n\nBy 2015, Twitch had more than 100 million viewers per month. In 2017, Twitch remained the leading live streaming video service for video games in the US, and had an advantage over YouTube Gaming, which shut down its standalone app in May 2019.

        "answer": "Yes, they do.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nIn particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.",

Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming.\n\nDue to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing more intense storms, droughts, and other weather extremes. Rapid environmental change in mountains, coral reefs, and the Arctic is forcing many species to relocate or become extinct. Even if efforts to minimise future warming are successful, some effects will continue for centuries. These include ocean heating, ocean acidification and sea level rise.",

The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources, and from grey, brown or black hydrogen, which is obtained from fossil sources or from the electrolysis of water. Natural hydrogen may be renewable, non-polluting and allows for lower cost operation compared to industrial hydrogen. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.\n\nOrigin of natural hydrogen\nThere are several sources of natural hydrogen:\n\n- degassing of deep hydrogen from the Earth's crust and mantle;\n- reaction of water with ultrabasic rocks (serpentinisation);\n- contact of water with reducing agents in the Earth's mantle;\n- interaction of water with freshly exposed rock surfaces (weathering);\n- decomposition of hydroxyl ions in the structure of minerals;\n- Natural radiolysis of water;\n- decomposition of organic matter;\n- biological activity\n- Extraction\n- Natural hydrogen is extracted from wells, mixed with other gases such as nitrogen or helium.\n\nSeveral sources have been identified in France. Geologists Alain Prinzhofer and Eric Derville have demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States. However, their potential remains difficult to assess.\n\nNumerous emanations on the ocean floor have been identified but are difficult to exploit. The discovery of a significant emergence in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.\n\nGeology\nNatural hydrogen is generated continuously from a variety of natural sources. There are many known hydrogen emergences on mid-ocean ridges. Another of the known reactions, serpentinisation, occurs under the sea floor (in the oceanic crust).\n\nDiagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably in Russia. Other sources are being explored, such as mantle hydrogen, or hydrogen from radiolysis (natural electrolysis) or from bacterial activity. In France, the Alps and Pyrenees are suitable for exploitation. New Caledonia has hyperalkaline sources that show dihydrogen emissions. A large accumulation of natural hydrogen was discovered in Bourakebougou (Mali).\n\nCharacteristics\nDihydrogen is very soluble in fresh water, especially at depth (solubility increases with pressure).\n\nhttps://en.wikipedia.org/wiki/Natural_hydrogen",

        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed.",

        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nIn this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations (Kim, 2014), and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models",

We performed experiments using large, diverse, manually annotated, and publicly available datasets for cyberbullying detection in social media. We cover three different types of social networks: teen oriented Q&A forum (Formspring), large microblogging platform (Twitter), and collaborative knowledge repository (Wikipedia talk pages). Each dataset addresses a different topic of cyberbullying. Twitter dataset contains examples of racism and sexism. Wikipedia dataset contains examples of personal attack. However, Formspring dataset is not specifically about any single topic. All three datasets have the problem of class imbalance where posts labeled as cyberbullying are in the minority as compared to neutral posts. Variation in the number of posts across datasets also affects vocabulary size that represents the number of distinct words encountered in the dataset. We measure the size of a post in terms of the number of words in the post. For each dataset, there are only a few posts with large size. We truncate such large posts to the size of post ranked at 95 percentile in that dataset. For example, in Wikipedia dataset, the largest post has 2846 words. However, size of post ranked at 95 percentile in that dataset is only 231. Any post larger than size 231 in Wikipedia dataset will be truncated by considering only first 231 words. This truncation affects only a small minority of posts in each dataset. However, it is required for efficiently training various models in our experiments. Details of each dataset are as follows.\nFormspring BIBREF2 : It was a question and answer based website where users could openly invite others to ask and answer questions. The dataset includes 12K annotated question and answer pairs. Each post is manually labeled by three workers. Among these pairs, 825 were labeled as containing cyberbullying content by at least two Amazon Mechanical turk workers.\nTwitter BIBREF3 : This dataset includes 16K annotated tweets. The authors bootstrapped the corpus collection, by performing an initial manual search of common slurs and terms used pertaining to religious, sexual, gender, and ethnic minorities. Of the 16K tweets, 3117 are labeled as sexist, 1937 as racist, and the remaining are marked as neither sexist nor racist.\nWikipedia BIBREF4 : For each page in Wikipedia, a corresponding talk page maintains the history of discussion among users who participated in its editing. This data set includes over 100k labeled discussion comments from English Wikipedia's talk pages. Each comment was labeled by 10 annotators via Crowdflower on whether it contains a personal attack. There are total 13590 comments labeled as personal attack.\nWe performed experiments using large, diverse, manually annotated, and publicly available datasets for cyberbullying detection in social media.

In laws and administrative regulations, the frequencies of person, location and organization are not high enough for NER experiments. Court decisions, on the other hand, include person, location, organization, references to law, other decision and regulation.\nCourt decisions from 2017 and 2018 were selected for the dataset, published online by the Federal Ministry of Justice and Consumer Protection. The documents originate from seven federal courts: Federal Labour Court (BAG), Federal Fiscal Court (BFH), Federal Court of Justice (BGH), Federal Patent Court (BPatG), Federal Social Court (BSG), Federal Constitutional Court (BVerfG) and Federal Administrative Court (BVerwG).\nFrom the table of contents, 107 documents from each court were selected (see Table ).

BIBREF1 picard1997affective provides a detailed discussion of the importance of affect analysis in human communication and interaction. Within this context the analysis of human affect from text is an important topic in natural language understanding, examples of which include sentiment analysis from Twitter BIBREF2 , affect analysis from poetry BIBREF3 and studies of correlation between function words and social/psychological processes BIBREF4 . People exchange verbal messages which not only contain syntactic information, but also information conveying their mental and emotional states. Examples include the use of emotionally colored words (such as furious and joy) and swear words. The automated processing of affect in human verbal communication is of great importance to understanding spoken language systems, particularly for emerging applications such as dialogue systems and conversational agents.\nStatistical language modeling is an integral component of speech recognition systems, with other applications such as machine translation and information retrieval. There has been a resurgence of research effort in recurrent neural networks for language modeling BIBREF5 , which have yielded performances far superior to baseline language models based on n-gram approaches. However, there has not been much effort in building neural language models of text that leverage affective information. Current literature on deep learning for language understanding focuses mainly on representations based on word semantics BIBREF6 , encoder-decoder models for sentence representations BIBREF7 , language modeling integrated with symbolic knowledge BIBREF8 and neural caption generation BIBREF9 , but to the best of our knowledge there has been no work on augmenting neural language modeling with affective information, or on data-driven approaches to generate emotional text.\nMotivated by these advances in neural language modeling and affective analysis of text, in this paper we propose a model for representation and generation of emotional text, which we call the Affect-LM. Our model is trained on conversational speech corpora, common in language modeling for speech recognition applications BIBREF10 . Figure 1 provides an overview of our Affect-LM and its ability to generate emotionally colored conversational text in a number of affect categories with varying affect strengths. While these parameters can be manually tuned to generate conversational text, the affect category can also be automatically inferred from preceding context words. Specifically for model training, the affect category is derived from features generated using keyword spotting from a dictionary of emotional words, such as the LIWC (Linguistic Inquiry and Word Count) tool BIBREF11 . Our primary research questions in this paper are:\nQ1:Can Affect-LM be used to generate affective sentences for a target emotion with varying degrees of affect strength through a customizable model parameter?\nQ2:Are these generated sentences rated as emotionally expressive as well as grammatically correct in an extensive crowd-sourced perception experiment?\nQ3:Does the automatic inference of affect category from the context words improve language modeling performance of the proposed Affect-LM over the baseline as measured by perplexity?\nThe remainder of this paper is organized as follows. In Section \"Related Work\" , we discuss prior work in the fields of neural language modeling, and generation of affective conversational text. In Section \"LSTM Language Model\" we describe the baseline LSTM model and our proposed Affect-LM model. Section \"Experimental Setup\" details the experimental setup, and in Section \"Results\" , we discuss results for customizable emotional text generation, perception studies for each affect category, and perplexity improvements over the baseline model before concluding the paper in Section \"Conclusions and Future Work\" .\nMotivated by these advances in neural language modeling and affective analysis of text, in this paper we propose a model for representation and generation of emotional text, which we call the Affect-LM.",

        "evidence": "Summer is traditionally associated with hot or warm weather. In Mediterranean climates, it is also associated with dry weather, while in other places (particularly in Eastern Asia because of the monsoon) it is associated with rainy weather. The wet season is the main period of vegetation growth within the savanna climate regime. Where the wet season is associated with a seasonal shift in the prevailing winds, it is known as a monsoon.\nIn the northern Atlantic Ocean, a distinct tropical cyclone season occurs from 1 June to 30 November. The statistical peak of the Atlantic hurricane season is 10 September. The Northeast Pacific Ocean has a broader period of activity, but in a similar timeframe to the Atlantic. The Northwest Pacific sees tropical cyclones year-round, with a minimum in February and March and a peak in early September. In the North Indian basin, storms are most common from April to December, with peaks in May and November. In the Southern Hemisphere, the tropical cyclone season runs from the start of November until the end of April with peaks in mid-February to early March.\nThunderstorm season in the United States and Canada runs in the spring through summer but sometimes can run as late as October or even November in the fall.

Many of its ideas are considered fundamental principles of liberal democracy, while the values and institutions it created remain central to French political discourse.\n\nIts causes are generally agreed to be a combination of social, political and economic factors, which the Ancien Régime proved unable to manage. In May 1789, widespread social distress led to the convocation of the Estates General, which was converted into a National Assembly in June. Continuing unrest culminated in the Storming of the Bastille on 14 July, which led to a series of radical measures by the Assembly, including the abolition of feudalism, the imposition of state control over the Catholic Church in France, and extension of the right to vote.",

        "evidence": "To solve this problem, we need a state tracking model independent of dialogue slots. In other words, the network should depend on the semantic similarity between slots and utterance instead of slot-specific modules. To this end, we propose the Slot-Independent Model (SIM). Our model complexity does not increase when the number of slots in dialogue tasks go up. Thus, SIM has many fewer parameters than existing dialogue state tracking models. To compensate for the exclusion of slot-specific parameters, we incorporate better feature representation of user utterance and dialogue states using syntactic information and convolutional neural networks (CNN). The refined representation, in addition to cross and self-attention mechanisms, make our model achieve even better performance than slot-specific models. For instance, on Wizard-of-Oz (WOZ) 2.0 dataset BIBREF8, the SIM model obtains a joint-accuracy score of 89.5%, 1.4% higher than the previously best model GLAD, with only 22% of the number of parameters. On DSTC2 dataset, SIM achieves comparable performance with previous best models with only 19% of the model size.\nThus, SIM has many fewer parameters than existing dialogue state tracking models.

They find that users prefer a full-sentence collaborative setup (vs. shorter fragments) but are mixed with regard to the system-driven approach to interaction. roemmele2017eval experiment with a user-driven setup, where the machine doesn't generate until the user requests it to, and then the user can edit or delete at will. They leverage user-acceptance or rejection of suggestions as a tool for understanding the characteristics of a helpful generation. All of these systems involve the user in the story-writing process, but lack user involvement in the story-planning process, and so they lean on the user's ability to knit a coherent overall story together out of locally related sentences. They also do not allow a user to control the novelty or “unexpectedness” of the generations, which clark2018mil find to be a weakness. Nor do they enable iteration; a user cannot revise earlier sentences and have the system update later generations. We develop a system that allows a user to interact in all of these ways that were limitations in previous systems; it enables involvement in planning, editing, iterative revising, and control of novelty. We conduct experiments to understand which types of interaction are most effective for improving stories and for making users satisfied and engaged. We have two main interfaces that enable human interaction with the computer. There is cross-model interaction, where the machine does all the composition work, and displays three different versions of a story written by three distinct models for a human to compare.

The second interface is intra-model interaction, where a human can select the model to interact with (potentially after having chosen it via cross-model), and can collaborate at all stages to jointly create better stories. The full range of interactions available to a user is: select a model, provide a topic, change diversity of content, collaborate on the planning for the story, and collaborate on the story sentences. It is entirely user-driven, as the users control how much is their own work and how much is the machine's at every stage. It supports revision; a user can modify an earlier part of a written story or of the story plan at any point, and observe how this affects later generations.\nWe have two main interfaces that enable human interaction with the computer.

Additionally, with three experts per problem, we are very likely to discover most missing hypotheses and incorrect entailments.\nIn our compilation of answers, we have marked 42 problems as straight “No”, 64 as “Yes” with missing implicit hypotheses and “44” as plain “Yes”. This means that, we expect, in our opinion, 28% of problems to be incorrectly labeled in RTE3 even assuming reasonable world knowledge. An additional 42% of problems require additional (yet reasonable to assume) hypotheses for entailment to hold formally, as prescribed by RTE3. This leaves only 30% of problems to acceptable as such. The reason that the amount of doubt is larger than in the average numbers quoted above is that, for many problems, certain missing hypotheses and/or error were not detected by a majority experts, but, after careful inspection, we judge that the minority report is justified.\nWe have additionally tagged each missing hypothesis according to the following classification:\nIn the process, we have gather a total of 449 expert judgments (one expert failed to answer a given problem), 146 missing hypotheses and 47 explanations for negative judgments.",

        "question": "How to evaluate binary paragraph vectors?",
        "answer": "The authors evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora.",
        "evidence": "One of the significant challenges in contemporary information processing is the sheer volume of available data. BIBREF0 , for example, claim that the amount of digital data in the world doubles every two years. This trend underpins efforts to develop algorithms that can efficiently search for relevant information in huge datasets. One class of such algorithms, represented by, e.g., Locality Sensitive Hashing BIBREF1 , relies on hashing data into short, locality-preserving binary codes BIBREF2 . The codes can then be used to group the data into buckets, thereby enabling sublinear search for relevant information, or for fast comparison of data items. Most of the algorithms from this family are data-oblivious, i.e. can generate hashes for any type of data. Nevertheless, some methods target specific kind of input data, like text or image.\nIn this work we focus on learning binary codes for text documents. An important work in this direction has been presented by BIBREF3 . Their semantic hashing leverages autoencoders with sigmoid bottleneck layer to learn binary codes from a word-count bag-of-words (BOW) representation. Salakhutdinov & Hinton report that binary codes allow for up to 20-fold improvement in document ranking speed, compared to real-valued representation of the same dimensionality. Moreover, they demonstrate that semantic hashing codes used as an initial document filter can improve precision of TF-IDF-based retrieval. Learning binary representation from BOW, however, has its disadvantages. First, word-count representation, and in turn the learned codes, are not in itself stronger than TF-IDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such high-dimensional vectors is impractical. Salakhutdinov & Hinton restricted the BOW vocabulary in their experiments to 2000 most frequent words.\nBinary codes have also been applied to cross-modal retrieval where text is one of the modalities. Specifically, BIBREF4 incorporated tag information that often accompany text documents, while BIBREF5 employed siamese neural networks to learn single binary representation for text and image data.\nRecently several works explored simple neural models for unsupervised learning of distributed representations of words, sentences and documents. BIBREF6 proposed log-linear models that learn distributed representations of words by predicting a central word from its context (CBOW model) or by predicting context words given the central word (Skip-gram model). The CBOW model was then extended by BIBREF7 to learn distributed representations of documents. Specifically, they proposed Paragraph Vector Distributed Memory (PV-DM) model, in which the central word is predicted given the context words and the document vector. During training, PV-DM learns the word embeddings and the parameters of the softmax that models the conditional probability distribution for the central words. During inference, word embeddings and softmax weights are fixed, but the gradients are backpropagated to the inferred document vector. In addition to PV-DM, Le & Mikolov studied also a simpler model, namely Paragraph Vector Distributed Bag of Words (PV-DBOW). This model predicts words in the document given only the document vector. It therefore disregards context surrounding the predicted word and does not learn word embeddings. Le & Mikolov demonstrated that paragraph vectors outperform BOW and bag-of-bigrams in information retrieval task, while using only few hundreds of dimensions. These models are also amendable to learning and inference over large vocabularies. Original CBOW network used hierarchical softmax to model the probability distribution for the central word. One can also use noise-contrastive estimation BIBREF8 or importance sampling BIBREF9 to approximate the gradients with respect to the softmax logits.\nAn alternative approach to learning representation of pieces of text has been recently described by BIBREF10 . Networks proposed therein, inspired by the Skip-gram model, learn to predict surrounding sentences given the center sentence. To this end, the center sentence is encoded by an encoder network and the surrounding sentences are predicted by a decoder network conditioned on the center sentence code. Once trained, these models can encode sentences without resorting to backpropagation inference. However, they learn representations at the sentence level but not at the document level.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PV-DM that learn short binary codes for text documents. One inspiration for binary paragraph vectors comes from a recent work by BIBREF11 on learning binary codes for images. Specifically, we introduce a sigmoid layer to the paragraph vector models, and train it in a way that encourages binary activations. We demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes. We also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora. Finally, we study models that simultaneously learn short binary codes for document filtering and longer, real-valued representations for ranking. While BIBREF11 employed a supervised criterion to learn image codes, binary paragraph vectors remain unsupervised models: they learn to predict words in documents.\nWe also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora.",

        "evidence": "Extractive multi-document summarization (MDS) aims to summarize a collection of documents by selecting a small number of sentences that represent the original content appropriately. Typical objectives for assembling a summary include information coverage and non-redundancy. A wide variety of methods have been introduced to approach MDS.\nMany approaches are based on sentence ranking, i.e. assigning each sentence a score that indicates how well the sentence summarizes the input BIBREF0 , BIBREF1 , BIBREF2 . A summary is created by selecting the top entries of the ranked list of sentences. Since the sentences are often treated separately, these models might allow redundancy in the summary. Therefore, they are often extended by an anti-redundancy filter while de-queuing ranked sentence lists.\nOther approaches work at summary-level rather than sentence-level and aim to optimize functions of sets of sentences to find good summaries, such as KL-divergence between probability distributions BIBREF3 or submodular functions that represent coverage, diversity, etc. BIBREF4 \nThe centroid-based model belongs to the former group: it represents sentences as bag-of-word (BOW) vectors with TF-IDF weighting and uses a centroid of these vectors to represent the whole document collection BIBREF5 . The sentences are ranked by their cosine similarity to the centroid vector. This method is often found as a baseline in evaluations where it usually is outperformed BIBREF0 , BIBREF6 .\nThis baseline can easily be adapted to work at the summary-level instead the sentence level. This is done by representing a summary as the centroid of its sentence vectors and maximizing the similarity between the summary centroid and the centroid of the document collection. A simple greedy algorithm is used to find the best summary under a length constraint.\nIn order to keep the method efficient, we outline different methods to select a small number of candidate sentences from each document in the input collection before constructing the summary.\nWe test these modifications on the DUC2004 dataset for multi-document summarization. The results show an improvement of Rouge scores over the original centroid method. The performance is on par with state-of-the-art methods which shows that the similarity between a summary centroid and the input centroid is a well-suited function for global summary optimization.\nThe summarization approach presented in this paper is fast, unsupervised and simple to implement. Nevertheless, it performs as well as more complex state-of-the-art approaches in terms of Rouge scores on the DUC2004 dataset. It can be used as a strong baseline for future research or as a fast and easy-to-deploy summarization tool.\nThe performance is on par with state-of-the-art methods which shows that the similarity between a summary centroid and the input centroid is a well-suited function for global summary optimization.",

        "answer": "Yes, it does.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nWe find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.",

        "evidence": "Knowledge-based question answering (KBQA) aims to answer natural language questions over knowledge bases (KBs) such as DBpedia and Freebase. Formal query generation is an important component in many KBQA systems BIBREF0 , BIBREF1 , BIBREF2 , especially for answering complex questions. Given entity and relation linking results, formal query generation aims to generate correct executable queries, e.g., SPARQL queries, for the input natural language questions. An example question and its formal query are shown in Figure FIGREF1 . Generally speaking, formal query generation is expected to include but not be limited to have the capabilities of (i) recognizing and paraphrasing different kinds of constraints, including triple-level constraints (e.g., “movies\" corresponds to a typing constraint for the target variable) and higher level constraints (e.g., subgraphs). For instance, “the same ... as\" represents a complex structure shown in the middle of Figure FIGREF1 ; (ii) recognizing and paraphrasing aggregations (e.g., “how many\" corresponds to Count); and (iii) organizing all the above to generate an executable query BIBREF3 , BIBREF4 .\nThere are mainly two kinds of query generation approaches for complex questions. (i) Template-based approaches choose a pre-collected template for query generation BIBREF1 , BIBREF5 . Such approaches highly rely on the coverage of templates, and perform unstably when some complex templates have very few natural language questions as training data. (ii) Approaches based on semantic parsing and neural networks learn entire representations for questions with different query structures, by using a neural network following the encode-and-compare framework BIBREF2 , BIBREF4 . They may suffer from the lack of training data, especially for long-tail questions with rarely appeared structures. Furthermore, both above approaches cannot handle questions with unseen query structures, since they cannot generate new query structures.\nTo cope with the above limitations, we propose a new query generation approach based on the following observation: the query structure for a complex question may rarely appear, but it usually contains some substructures that frequently appeared in other questions. For example, the query structure for the question in Figure FIGREF1 appears rarely, however, both “how many movies\" and “the same ... as\" are common expressions, which correspond to the two query substructures in dashed boxes. To collect such frequently appeared substructures, we automatically decompose query structures in the training data. Instead of directly modeling the query structure for the given question as a whole, we employ multiple neural networks to predict query substructures contained in the question, each of which delivers a part of the query intention. Then, we select an existing query structure for the input question by using a combinational ranking function. Also, in some cases, no existing query structure is appropriate for the input question. To cope with this issue, we merge query substructures to build new query structures. The contributions of this paper are summarized below:\nInstead of directly modeling the query structure for the given question as a whole, we employ multiple neural networks to predict query substructures contained in the question, each of which delivers a part of the query intention.",

        "answer": "Yes, it does.",
        "evidence": "The pre-trained language model, BERT BIBREF0 has led to a big breakthrough in various kinds of natural language understanding tasks. Ideally, people can start from a pre-trained BERT checkpoint and fine-tune it on a specific downstream task. However, the original BERT models are memory-exhaustive and latency-prohibitive to be served in embedded devices or CPU-based online environments. As the memory and latency constraints vary in different scenarios, the pre-trained BERT model should be adaptive to different requirements with accuracy retained to the largest extent. Existing BERT-oriented model compression solutions largely depend on knowledge distillation BIBREF1, which is inefficient and resource-consuming because a large training corpus is required to learn the behaviors of a teacher. For example, DistilBERT BIBREF2 is re-trained on the same corpus as pre-training a vanilla BERT from scratch; and TinyBERT BIBREF3 utilizes expensive data augmentation to fit the distillation target. The costs of these model compression methods are as large as pre-training and unaffordable for low-resource settings. Therefore, it is straight-forward to ask, can we design a lightweight method to generate adaptive models with comparable accuracy using significantly less time and resource consumption? In this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions. Specifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation. Initially, the architecture and weights of student model are inherited from the BERT teacher. In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation. Because weight pruning and matrix factorization help to generate better initial and intermediate status\nin the knowledge distillation iterations, the accuracy and efficiency of model compression can be greatly improved.\nWe conduct extensive experiments on five public datasets of natural language understanding. As an example, the performance comparison of LadaBERT and state-of-the-art models on MNLI-m dataset is illustrated in Figure FIGREF1. We can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios. Especially, LadaBERT-1 outperforms BERT-PKD significantly under $2.5\\times $ compression ratio, and LadaBERT-3 outperforms TinyBERT under $7.5\\times $ compression ratio while the training speed is accelerated by an order of magnitude.\nThe rest of this paper is organized as follows. First, we summarizes the related works of model compression and their applications to BERT in Section SECREF2. Then, the methodology of LadaBERT is introduced in Section SECREF3, and experimental results are presented in Section SECREF4. At last, we conclude this work and discuss future works in Section SECREF5.\nWe can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios.",

In nineteenth and early twentieth century Europe, artwork was a common form of racialization which targeted countries in the Middle East and Asia. The artwork, predominantly paintings, were portrayed in order to instill prejudice in the Western populations through sexualizing and manipulating images. One of the most prominent examples of Orientalist work in art is a piece by Eugène Delacroix titled Women of Algiers in their Apartment. Dating back to 1834, it portrays three women resting in a harem in exotic clothing while an African woman is dressed in plain clothing, depicting her role as a servant. Fine textiles, hookahs, and other paraphernalia adorn the room, which represents a European fantasy of an exotic scene. Attempts to portray these cultures as strange, foreign and exotic through Orientalism led to intolerance towards the Arab and Asian communities in Europe and the United States. Others argue that Delacroix, who travelled in North Africa sketching extensively, was depicting a realistic scene of the era based on his first-hand knowledge and experience. In such an interpretation the clothing, for example, is consistent with the times, as Arab North Africans dressed differently from Europeans, and kept black slaves who would not have been treated as equals.",

However, obtaining training data for creating such prediction models can be very costly as it involves the step which these models are trying to automate – manual data extraction. Furthermore, depending on the task at hand, the types of information being extracted may vary significantly. For example, in systematic reviews of randomized controlled trials this information generally includes the patient group, the intervention being tested, the comparison, and the outcomes of the study (PICO elements) BIBREF4 . In toxicology research the extraction may focus on routes of exposure, dose, and necropsy timing BIBREF1 . Previous work has largely focused on identifying specific pieces of information such as biomedical events BIBREF6 or PICO elements BIBREF0 . However, depending on the domain and the end goal of the extraction, these may be insufficient to comprehensively describe a given study.\nTherefore, in this paper we focus on unsupervised methods for identifying text segments (such as sentences or fixed length sequences of words) relevant to the information being extracted. We develop a model that can be used to identify text segments from text documents without labeled data and that only requires the current document itself, rather than an entire training corpus linked to the target document. More specifically, we utilize representation learning methods BIBREF7 , where words or phrases are embedded into the same vector space. This allows us to compute semantic relatedness among text fragments, in particular sentences or text segments in a given document and a short description of the type of information being extracted from the document, by using similarity measures in the feature space. The model has the potential to speed up identification of relevant segments in text and therefore to expedite annotation of domain specific information without reliance on costly labeled data.\nWe have developed and tested our approach on a reference database of rodent uterotropic bioassays BIBREF1 which are labeled according to their adherence to test guidelines set forth in BIBREF3 . Each study in the database is assigned a label determining whether or not it met each of six main criteria defined by the guidelines; however, the database does not contain sentence-level annotations or any information about where the criteria was mentioned in each publication. Due to the lack of fine-grained annotations, supervised learning methods cannot be easily applied to aid annotating new publications or to annotate related but distinct types of studies. This database therefore presents an ideal use-case for unsupervised approaches.\nWhile our approach doesn't require any labeled data to work, we use the labels available in the dataset to evaluate the approach. We train a binary classification model for identifying publications which satisfied given criteria and show the model performs better when trained on relevant sentences identified by our method than when trained on sentences randomly picked from the text. Furthermore, for three out of the six criteria, a model trained solely on the relevant sentences outperforms a model which utilizes full text. The results of our evaluation support the intuition that semantic relatedness to criteria descriptions can help in identifying text sequences discussing sought after information.\nThere are two main contributions of this work. We present an unsupervised method that employs representation learning to identify text segments from publication full text which are relevant to/contain specific sought after information (such as number of dose groups). In addition, we explore a new dataset which hasn't been previously used in the field of information extraction.\nThe remainder of this paper is organized as follows. In the following section we provide more details of the task and the dataset used in this study. In Section SECREF3 we describe our approach. In Section SECREF4 we evaluate our model and discuss our results. In Section SECREF5 we compare our work to existing approaches. Finally, in Section SECREF6 we provide ideas for further study.\nWe have developed and tested our approach on a reference database of rodent uterotropic bioassays2 (Kleinstreuer et al., 2016) which are labeled according to their adherence to test guidelines set forth in (OECD, 2007).",

There were other potential claimants, including the powerful English earl Harold Godwinson, whom Edward named as king on his deathbed in January 1066. Arguing that Edward had previously promised the throne to him and that Harold had sworn to support his claim, William built a large fleet and invaded England in September 1066. He decisively defeated and killed Harold at the Battle of Hastings on 14 October 1066. After further military efforts, William was crowned king on Christmas Day, 1066, in London. He made arrangements for the governance of England in early 1067 before returning to Normandy. Several unsuccessful rebellions followed, but William's hold was mostly secure on England by 1075, allowing him to spend the greater part of his reign in continental Europe.",

William invaded England, where he won the Battle of Hastings, defeating earl Harold Godwinson. A number of battles followed, but William became King of England late in 1066.

        "answer": "Yes, it does.",
        "evidence": "Learning semantic representations (embeddings) of different entities, such as textual, commercial, and physical, has been a recent and active area of research. Such representations can facilitate applications that rely on a notion of similarity, for example recommendation systems and ranking algorithms in e-commerce.\nIn natural language processing, word2vec BIBREF0 learns vector representations of words from large quantities of text, where each word is mapped to a $d$-dimensional vector such that semantically similar words have geometrically closer vectors. This is achieved by predicting either the context words appearing in a window around a given target word (skip-gram model), or the target word given the context (CBOW model). The main assumption is that words appearing frequently in similar contexts share statistical properties (the distributional hypothesis). Crucially, word2vec models, like many other word embedding models, preserve sequential information encoded in text so as to leverage word co-occurrence statistics. The skip-gram model has been adapted to other domains in order to learn dense representations of items other than words. For example, product embeddings in e-commerce BIBREF1 or vacation rental embeddings in the hospitality domain BIBREF2 can be learned by treating purchase histories or user click sequences as sentences and applying a word2vec approach.\nMost of the prior work on item embedding exploit the co-occurrence of items in a sequence as the main signal for learning the representation. One disadvantage of this approach is that it fails to incorporate rich structured information associated with the embedded items. For example, in the travel domain, where we seek to embed hotels and other travel-related entities, it could be helpful to encode explicit information such as user ratings, star ratings, hotel amenities, and location in addition to implicit information encoded in the click-stream.\nIn this work, we propose an algorithm for learning hotel embeddings that combines sequential user click information in a word2vec approach with additional structured information about hotels. We propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes. In experimental results, we show that enhancing the neural network to jointly encode click and supplemental structured information outperforms a skip-gram model that encodes the click information alone. The proposed architecture also naturally handles the cold-start problem for hotels with little or no historical clicks. Specifically, we can infer an embedding for these properties by leveraging their supplemental structured metadata.\nCompared to previous work on item embeddings, the novel contributions of this paper are as follows:\nWe propose a novel framework for fusing multiple sources of information about an item (such as user click sequences and item-specific information) to learn item embeddings via self-supervised learning.\nWe generate an interpretable embedding which can be decomposed into sub-embeddings for clicks, location, ratings, and attributes, and employed either as separate component embeddings or a single, unified embedding.\nIt is also dynamic, meaning it is easy to reflect future changes in attributes such as star-rating or addition of amenities in the embedding vectors without retraining.\nWe address the cold-start problem by including hotel metadata which are independent of user click-stream interactions and available for all hotels. This helps us to better impute embeddings for sparse items/hotels.\nWe show significant gains over previous work based on click-embedding in several experimental studies.\nThe structure of the remainder of this paper is as follows. Section 2 gives an overview of some of the recent works on neural embedding. Section 3 provides details of the proposed framework, including the neural network architecture, training methodology, and how the cold-start problem is addressed. In Section 4, we present experimental results on several different tasks and a comparison with previous state-of-the-art work. Section 5 concludes the paper.\nIn experimental results, we show that enhancing the neural network to jointly encode click and supplemental structured information outperforms a skip-gram model that encodes the click information alone.",

        "answer": "Yes, it does.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nThe experimental results show that the proposed approach performs the best among all the comparison systems.",

        "answer": "They studied the dependence of quality of the partitions against the number of neighbours, k, in the MST-kNN graph.",
        "evidence": "Our framework consists of a series of steps for which there are choices and alternatives. Although it is not possible to provide comparisons to the myriad of methods and possibilities available, we have examined quantitatively the robustness of the results to parametric and methodological choices in different steps of the framework: (i) the importance of using Doc2Vec embeddings instead of BoW vectors, (ii) the size of training corpus for Doc2Vec; (iii) the sparsity of the MST-kNN similarity graph construction. We have also carried out quantitative comparisons to other methods, including: (i) LDA-BoW, and (ii) clustering with other community detection methods. We provide a brief summary here and additional material in the SI.\nThe use of fixed-sized vector embeddings (Doc2Vec) instead of standard bag of words (BoW) is an integral part of our pipeline. Doc2Vec produces lower dimensional vector representations (as compared to BoW) with higher semantic and syntactic content. It has been reported that Doc2Vec outperforms BoW representations in practical benchmarks of semantic similarity, as well as being less sensitive to hyper-parameters BIBREF22 .\nTo quantify the improvement provided by Doc2Vec in our framework, we constructed a MST-kNN graph following the same steps but starting with TF-iDF vectors for each document. We then ran MS on this TF-iDF similarity graph, and compared the results to those obtained from the Doc2Vec similarity graph. Figure 7 shows that the Doc2Vec version outperforms the BoW version across all resolutions in terms of both $NMI$ and $\\widehat{PMI}$ scores.\nAs shown in Table 1 , we have tested the effect of the size of the training corpus on the Doc2Vec model. We trained Doc2Vec on two additional training sets of 1 million and 2 million records (randomly chosen from the full set of $\\sim $ 13 million records). We then followed the same procedure to construct the MST-kNN similarity graph and carried out the MS analysis. The results, presented in Figure S3 in the SI, show that the performance is affected only mildly by the size of the Doc2Vec training set.\nTo examine the effect of sparsification in the graph construction, we have studied the dependence of quality of the partitions against the number of neighbours, $k$ , in the MST-kNN graph. Our numerics, shown in Figure S4 in the SI, indicate that both the $NMI$ and $\\widehat{PMI}$ scores of the MS clusterings reach a similar level of quality for values of $k$ above 13-16, with minor improvement after that. Hence our results are robust to the choice of $k$ , provided it is not too small. Due to computational efficiency, we thus favour a relatively small $k$ , but not too small.\nWe carried out a comparison with LDA, a widely used methodology for text analysis. A key difference between standard LDA and our MS method is the fact that a different LDA model needs to be trained separately for each number of topics pre-determined by the user. To offer a comparison across the methods, We obtained five LDA models corresponding to the five MS levels we considered in detail. The results in Table 2 show that MS and LDA give partitions that are comparably similar to the hand-coded categories (as measured with $NMI$ ), with some differences depending on the scale, whereas the MS clusterings have higher topic coherence (as given by $\\widehat{PMI}$ ) across all scales.\nTo give an indication of the computational cost, we ran both methods on the same servers. Our method takes approximately 13 hours in total to compute both the Doc2Vec model on 13 million records (11 hours) and the full MS scan with 400 partitions across all resolutions (2 hours). The time required to train just the 5 LDA models on the same corpus amounts to 30 hours (with timings ranging from $\\sim $ 2 hours for the 3 topic LDA model to 12.5 hours for the 44 topic LDA model).\nThis comparison also highlights the conceptual difference between our multi-scale methodology and LDA topic modelling. While LDA computes topics at a pre-determined level of resolution, our method obtains partitions at all resolutions in one sweep of the Markov time, from which relevant partitions are chosen based on their robustness. However, the MS partitions at all resolutions are available for further investigation if so needed.\nWe have used several algorithms readily available in code libraries (i.e., the iGraph module for Python) to cluster/partition the same kNN-MST graph. Figure S5 in the SI shows the comparison against several well-known partitioning methods (Modularity Optimisation BIBREF44 , InfoMap BIBREF4 , Walktrap BIBREF45 , Label Propagation BIBREF46 , and Multi-resolution Louvain BIBREF35 ) which give just one partition (or two in the case of the Louvain implementation in iGraph) into a particular number of clusters, in contrast with our multiscale MS analysis. Our results show that MS provides improved or equal results to other graph partitioning methods for both $NMI$ and $\\widehat{PMI}$ across all scales. Only for very fine resolution with more than 50 clusters, Infomap, which partitions graphs into small clique-like subgraphs BIBREF32 , BIBREF47 , provides a slightly improved $NMI$ for that particular scale. Therefore, MS allows us to find relevant, yet high quality clusterings across all scales by sweeping the Markov time parameter.\nTo examine the effect of sparsification in the graph construction, we have studied the dependence of quality of the partitions against the number of neighbours, k, in the MST-kNN graph.",

Contested by 20 clubs, it operates on a system of promotion and relegation with the English Football League (EFL). Seasons typically run from August to May with each team playing 38 matches (playing all other teams both home and away). Most games are played on Saturday and Sunday afternoons, with occasional weekday evening fixtures.\n\nThe competition was founded as the FA Premier League on 20 February 1992 following the decision of clubs in the Football League First Division to break away from the Football League founded in 1888; however, teams may still be relegated into and promoted from the EFL Championship. The Premier League takes advantage of a lucrative television rights sale to Sky: from 2019 to 2020, the league's accumulated television rights deals were worth around £3.1 billion a year, with Sky and BT Group securing the domestic rights to broadcast 128 and 32 games respectively. The Premier League is a corporation where chief executive Richard Masters is responsible for its management, whilst the member clubs act as shareholders. Clubs were apportioned central payment revenues of £2.4 billion in 2016–17, with a further £343 million in solidarity payments to English Football League (EFL) clubs.\n\nThe Premier League is the most-watched sports league in the world, broadcast in 212 territories to 643 million homes and a potential TV audience of 4.7 billion people. For the 2018–19 season, the average Premier League match attendance was at 38,181, second to the German Bundesliga's 43,500, while aggregated attendance across all matches is the highest of any association football league at 14,508,981. Most stadium occupancies are near capacity. The Premier League ranks first in the UEFA coefficients of leagues based on performances in European competitions over the past five seasons as of 2021. The English top-flight has produced the second-highest number of UEFA Champions League/European Cup titles, with five English clubs having won fourteen European trophies in total.\n\nFifty clubs have competed since the inception of the Premier League in 1992: forty-eight English and two Welsh clubs.

        "question": "What benefits does the attention mechanism bring NMT?",
        "answer": "It can improve NMTs by allowing the NMT to decide which source words should attend the predicting process of the next target words.",
        "evidence": "Neural Machine Translation (NMT) has shown its effectiveness in translation tasks when NMT systems perform best in recent machine translation campaigns BIBREF0 , BIBREF1 . Compared to phrase-based Statistical Machine Translation (SMT) which is basically an ensemble of different features trained and tuned separately, NMT directly modeling the translation relationship between source and target sentences. Unlike SMT, NMT does not require much linguistic information and large monolingual data to achieve good performances.\nAn NMT consists of an encoder which recursively reads and represents the whole source sentence into a context vector and a recurrent decoder which takes the context vector and its previous state to predict the next target word. It is then trained in an end-to-end fashion to learn parameters which maximizes the likelihood between the outputs and the references. Recently, attention-based NMT has been featured in most state-of-the-art systems. First introduced by BIBREF2 , attention mechanism is integrated in decoder side as feedforward layers. It allows the NMT to decide which source words should take part in the predicting process of the next target words. It helps to improve NMTs significantly. Nevertheless, since the attention mechanism is specific to a particular source sentence and the considering target word, it is also specific to particular language pairs.\nSome recent work has focused on extending the NMT framework to multilingual scenarios. By training such network using parallel corpora in number of different languages, NMT could benefit from additional information embedded in a common semantic space across languages. Basically, the proposed NMT are required to employ multiple encoders or multiple decoders to deal with multilinguality. Furthermore, in order to avoid the tight dependency of the attention mechanism to specific language pairs, they also need to modify their architecture to combine either the encoders or the attention layers. These modifications are specific to the purpose of the tasks as well. Thus, those multilingual NMTs are more complicated, much more free parameters to learn and more difficult to perform standard trainings compared to the original NMT.\nIn this paper, we introduce a unified approach to seamlessly extend the original NMT to multilingual settings. Our approach allows us to integrate any language in any side of the encoder-decoder architecture with only one encoder and one decoder for all the languages involved. Moreover, it is not necessary to do any network modification to enable attention mechanism in our NMT systems. We then apply our proprosed framework in two demanding scenarios: under-resourced translation and zero-resourced translation. The results show that bringing multilinguality to NMT helps to improve individual translations. With some insightful analyses of the results, we set our goal toward a fully multilingual NMT framework.\nThe paper starts with a detailed introduction to attention-based NMT. In Section SECREF3 , related work about multi-task NMT is reviewed. Section SECREF5 describes our proposed approach and thorough comparisons to the related work. It is followed by a section of evaluating our systems in two aforementioned scenarios, in which different strategies have been employed under a unified approach (Section SECREF4 ).

        "evidence": "Gender bias describes an inherent prejudice against a gender, captured both by individuals and larger social systems. Word embeddings, a popular machine-learnt semantic space, have been shown to retain gender bias present in corpora used to train them BIBREF0. This results in gender-stereotypical vector analogies à la NIPS20135021, such as man:computer programmer :: woman:homemaker BIBREF1, and such bias has been shown to materialise in a variety of downstream tasks, e.g. coreference resolution BIBREF2, BIBREF3.\nBy operationalising gender bias in word embeddings as a linear subspace, DBLP:conf/nips/BolukbasiCZSK16 are able to debias with simple techniques from linear algebra. Their method successfully mitigates [author=simone,color=blue!40,size=,fancyline,caption=,]does not particularly like boldfacing for emphasis, but can live with.direct bias: man is no longer more similar to computer programmer in vector space than woman. However, the structure of gender bias in vector space remains largely intact, and the new vectors still evince indirect bias: associations which result from gender bias between not explicitly gendered words, for example a possible association between football and business resulting from their mutual association with explicitly masculine words BIBREF4. In this paper we continue the work of BIBREF4, and show that another paradigm for gender bias mitigation proposed by BIBREF5, Counterfactual Data Augmentation (CDA), is also unable to mitigate indirect bias. We also show, using a new test we describe (non-biased gender analogies), that WED might be removing too much gender information, casting further doubt on its operationalisation of gender bias as a linear subspace.\nTo improve CDA we make two proposals. The first, Counterfactual Data Substitution (CDS), is designed to avoid text duplication in favour of substitution. The second, the Names Intervention, is a method which can be applied to either CDA or CDS, and treats bias inherent in first names. It does so using a novel name pairing strategy that accounts for both name frequency and gender-specificity. Using our improvements, the clusters of the most biased words exhibit a reduction of cluster purity by an average of 49% across both corpora following treatment, thereby offering a partial solution to the problem of indirect bias as formalised by BIBREF4.

        "evidence": "Robotic Process Automation (RPA) is a type of software bots that simulates hand-operated human activities like entering data into a system, registering into accounts, and accomplishing straightforward but repetitive workflows BIBREF0. However, one of the drawbacks of RPA-bots is their susceptibility to changes in defined scenarios: being designed for a particular task, the RPA-bot is usually not adaptable to other domains or even light modifications in a workflow BIBREF0. This inability to readjust to shifting conditions gave rise to Intelligent Process Automation (IPA) systems. IPA-bots combine RPA with Artificial Intelligence (AI) and thus are able to execute more cognitively demanding tasks that require i.a. reasoning and language understanding. Hence, IPA-bots advanced beyond automating shallow “click tasks” and can perform jobs more intelligently – by means of machine learning algorithms. Such IPA-systems undertake time-consuming and routine tasks, and thus enable smart workflows and free up skilled workers to accomplish higher-value activities.\nOne of the potential applications of Natural Language Processing (NLP) within the IPA domain are conversational interfaces that enable human-to-machine interaction. The main benefit of conversational systems is their ability to give attention to several users simultaneously while supporting natural communication. A conventional dialogue system comprises multiple stages and involves different types of NLP subtasks, starting with Natural Language Understanding (NLU) (e.g., intent classification, named entity extraction) and going towards dialogue management (i.e., determining the next possible bot action, considering the dialogue history) and response generation (e.g., converting the semantic representation of the next system action into a natural language utterance). A typical dialogue system for IPA purposes undertakes shallow customer support requests (e.g., answering of FAQs), allowing human workers to focus on more sophisticated inquiries.\nRecent research in the dialogue generation domain is conducted by employing AI-techniques like machine and deep learning BIBREF1, BIBREF2. However, conventional supervised methods have limitations when applied to real-world data and industrial tasks. The primary challenge here refers to a training phase since a robust model requires an extensive amount of structured and labeled data, that is often not available for domain-specific problems. Especially if it concerns dialogue data, which has to be appropriately structured as well as labeled and annotated with additional information. Therefore, despite the popularity of deep learning end-to-end models, one still needs to rely on conventional pipelines in practical dialogue engineering, especially while setting a new domain. However, with few structured data available, transfer learning methods can be used. Such algorithms enable training of the systems with less or even a minimal amount of data, and are able to transfer the knowledge obtained during the training on existing data to the unseen domain.\nThe system has two purposes: First, it reduces repetitive and time-consuming activities and, therefore, allows workers of the e-learning platform to focus solely on complex questions; Second, by interacting with users, it augments the resources with structured and to some extent labeled training data for further possible implementation of learnable dialogue components (see Section SECREF5);",

If unimpeded, the light of the sun is white.\n\nBlue light has a shorter wavelength than other colors of light, and it scatters more easily. It is this scattering which makes it perceptible to the human eye.When the sun starts to set, the light is passing through even more atmosphere, and yet further colors are visible (such as orange and red).\n\nYou can read more at https://spaceplace.nasa.gov/blue-sky/en/, where I researched this answer.",

        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output).",

        "question": "Does their embedding space preserve the semantic properties of the conceptual elements that make up visual scenes?",
        "answer": "Yes.",
        "evidence": "Recently, there has been a significant increase in the investment for autonomous driving (AD) research and development, with the goal of achieving full autonomy in the next few years. Realizing this vision requires robust ML/AI algorithms that are trained on massive amounts of data. Thousands of cars, equipped with various types of sensors (e.g., LIDAR, RGB, RADAR), are now deployed around the world to collect this heterogeneous data from real-world driving scenes. The primary objective for AD is to use these data to optimize the vehicle's perception pipeline on such tasks as: 3D object detection, obstacle tracking, object trajectory forecasting, and learning an ideal driving policy. Fundamental to all of these tasks will be the vehicle's context understanding capability, which requires knowledge of the time, location, detected objects, participating events, weather, and various other aspects of a driving scene. Even though state-of-the-art AI technologies are used for this purpose, their current effectiveness and scalability are insufficient to achieve full autonomy. Humans naturally exhibit context understanding behind the wheel, where the decisions we make are the result of a continuous evaluation of perceptual cues combined with background knowledge. For instance, human drivers generally know which area of a neighborhood might have icy road conditions on a frigid winter day, where flooding is more frequent after a heavy rainfall, which streets are more likely to have kids playing after school, and which intersections have poor lighting. Currently, this type of common knowledge is not being used to assist self-driving cars and, due to the sample-inefficiency of current ML/AI algorithms, vehicle models cannot effectively learn these phenomena through statistical observation alone. On March 18, 2018, Elaine Herzberg’s death was reported as the first fatality incurred from a collision with an autonomous vehicle. An investigation into the collision, conducted by The National Transportation Safety Board (NTSB), remarks on the shortcomings of current AD and context understanding technologies. Specifically, NTSB found that the autonomous vehicle incorrectly classified Herzberg as an unknown object, a vehicle, and then a bicycle within the complex scene as she walked across the road. Further investigation revealed that the system design did not include consideration for pedestrians walking outside of a crosswalk, or jaywalking BIBREF9. Simply put, the current AD technology lacks fundamental understanding of the characteristics of objects and events within common scenes; this suggests that more research is required in order to achieve the vision of autonomous driving.\nKnowledge Graphs (KGs) have been successfully used to manage heterogeneous data within various domains. They are able to integrate and structure data and metadata from multiple modalities into a unified semantic representation, encoded as a graph. More recently, KGs are being translated into latent vector space representations, known as Knowledge Graph Embeddings (KGEs), that have been shown to improve the performance of machine learning models when applied to certain downstream tasks, such as classification BIBREF10, BIBREF11. Given a KG as a set of triples, KGE algorithms learn to create a latent representation of the KG entities and relations as continuous KGE vectors. This encoding allows KGEs to be easily manipulated and integrated with machine learning algorithms. Motivated by the shortcomings of current context understanding technologies, along with the promising outcomes of KGEs, our research focuses on the generation and evaluation of KGEs on AD data. Before directly applying KGEs on critical AD applications, however, we evaluate the intrinsic quality of KGEs across multiple metrics and KGE algorithms BIBREF12. Additionally, we present an early investigation of using KGEs for a selected use-case from the AD domain.\nDataset. To promote and enable further research on autonomous driving, several benchmark datasets have been made publicly available by companies in this domain BIBREF13. NuScenes is a benchmark dataset of multimodal vehicular data, recently released by Aptiv BIBREF14 and used for our experiments. NuScenes consists of a collection of 20-second driving scenes, with $\\sim $40 sub-scenes sampled per driving scene (i.e., one every 0.5 seconds). In total, NuScenes includes 850 driving scenes and 34,149 sub-scenes. Each sub-scene is annotated with detected objects and events, each defined within a taxonomy of 23 object/event categories.\nScene Ontology. In autonomous driving, a scene is defined as an observable volume of time and space BIBREF15. On the road, a vehicle may encounter many different situations|such as merging onto a divided highway, stopping at a traffic light, and overtaking another vehicle|all of which are considered as common driving scenes. A scene encapsulates all relevant information about a particular situation, including data from vehicular sensors, objects, events, time and location. A scene can also be divided into a sequence of sub-scenes. As an example, a 20-second drive consisting primarily of the vehicle merging into a highway could be considered as a scene. In addition, all the different situations the vehicle encounters within these 20 seconds can also be represented as (sub-)scenes. In this case, a scene may be associated with a time interval and spatial region while a sub-scene may be associated with a specific timestamp and a set of spatial coordinates. This semantic representation of a scene is formally defined in the Scene Ontology (see figure FIGREF8(a), depicted in Protege). To enable the generation of a KG from the data within NuScenes, the Scene Ontology is extended to include all the concepts (i.e., objects and event categories) found in the NuScenes dataset.\nGenerating Knowledge Graphs. The Scene Ontology identifies events and features-of-interests (FoIs) as top-level concepts. An event or a FoI may be associated with a Scene via the includes relation. FoIs are associated with events through the isParticipantOf relation. Figure FIGREF8(b) shows a subset of the FoIs and events defined by the Scene Ontology. In generating the scenes' KG, each scene and sub-scene found in NuScenes is annotated using the Scene Ontology. Table TABREF9 shows some basic statistics of the generated KG.\nKGE Algorithms. KGE algorithms enable the ability to easily feed knowledge into ML algorithms and improve the performance of learning tasks, by translating the knowledge contained in knowledge graphs into latent vector space representation of KGEs BIBREF16. To select candidate KGE algorithms for our evaluation, we referred to the classification of KGE algorithms provided by Wang et al. BIBREF17. In this work, KGE algorithms are classified into two primary categories: (1) Transitional distance-based algorithms and (2) Semantic matching-based models. Transitional distance-based algorithms define the scoring function of the model as a distance-based measure, while semantic matching-based algorithms define it as a similarity measure. Here, entity and relation vectors interact via addition and subtraction in the case of Transitional distance-based models; in semantic matching-based models, the interaction between entity and relation vectors is captured by multiplicative score functions BIBREF18.\nInitially, for our study we had selected one algorithm from each class: TransE BIBREF19 to represent the transitional distance-based algorithms and RESCAL BIBREF20 to represent the semantic matching-based algorithms. However, after experimentation, RESCAL did not scale well for handling large KGs in our experiments. Therefore, we also included HolE BIBREF21|an efficient successor of RESCAL|in the evaluation. A brief summary of each algorithm is provided for each model, below:\nTransE: the TransE model is often considered to be the most-representative of the class of transitional distance-based algorithms BIBREF17. Given a triple (h, r, t) from the KG, TransE encodes h, r and t as vectors, with r represented as a transition vector from h to t: $\\mathbf {h} + \\mathbf {r} \\approx \\mathbf {t}$. Since both entities and relations are represented as vectors, TransE is one of the most efficient KGE algorithms, with $\\mathcal {O}(n d + m d)$ space complexity and $\\mathcal {O}(n_t d)$ time complexity ($n_t$ is the number of training triples).\nRESCAL: RESCAL is capable of generating an expressive knowledge graph embedding space, due to its ability to capture complex patterns over multiple hops in the KG. RESCAL encodes relations as matrices and captures the interaction between entities and relations using a bi-linear scoring function. Though the use of a matrix to encode each relation yields improved expressivity, it also limits RESCAL’s ability to scale with large KGs. It has $\\mathcal {O}(n d + m d^2)$ space complexity and $\\mathcal {O}(n_t d^2)$ time complexity.\nHolE: HoLE is a more efficient successor of RESCAL, addressing its space and time complexity issues, by encoding relations as vectors without sacrificing the expressivity of the model. By using circular correlation operation BIBREF21, it captures the pairwise interaction of entities as composable vectors. This optimization yields $\\mathcal {O} (n d + m d)$ space complexity and $\\mathcal {O}(n_t d \\log d)$ time complexity.\nVisualizing KGEs. In order to visualize the generated KGE, a “mini\" KG from the NuScenes-mini dataset was created. Specifically, 10 scenes were selected (along with their sub-scenes) to generate the KG, and the TransE algorithm was used to learn the embeddings. When training the KGEs, we chose the dimension of the vectors to be 100. To visualize the embeddings in 2-dimensional (2D) space, the dimensions are reduced using the t-Distributed Stochastic Neighbor Embedding (t-SNE) BIBREF22 projection. Figure FIGREF11(a) shows the resulting embeddings of the NuScenes dataset. To denote interesting patterns that manifest in the embeddings, instances of Car (a FoI) and the events in which they participate are highlighted. In this image, events such as parked car, moving car, and stopped car are clustered around entities of type Car. This shows that the isParticipantOf relations defined in the KG are maintained within the KG embeddings.\n\nHere, we deviate slightly from the prior work in evaluating KGE algorithms, which evaluate KGEs based downstream task performance. Instead, we focus on an evaluation that uses only metrics that quantify the intrinsic quality of KGEs BIBREF23: categorization measure, coherence measure, and semantic transition distance. Categorization measures how well instances of the same type cluster together. To quantify this quality, all vectors of the same type are averaged together and the cosine similarity is computed between the averaged vector and the typed class. The Coherence measure quantifies the proportion of neighboring entities that are of the same type; the evaluation framework proposes that, if a set of entities are typed by the class, those entities should form a cluster in the embedding space with the typed class as the centroid. Adapted from the word embedding literature, Semantic Transitional Distance captures the relational semantics of the KGE: if a triple $(h,r,t)$ is correctly represented in the embedding space, the transition distance between the vectors representing $(\\mathbf {h+r})$ should be close to $\\mathbf {t}$. This is quantified by computing the cosine similarity between $(\\mathbf {h+r})$ and $\\mathbf {t}$.\nResults. Evaluation results are reported with respect to each algorithm and metric. Figure FIGREF13 shows the evaluation results of categorization measure, coherence measure, and semantic transitional distance|for each KGE algorithm. The NuScenes KG, generated from the NuScenes-trainval dataset, is large in terms of both the number of triples and number of entities (see Table TABREF9). Hence, RESCAL did not scale well to this dataset. For this reason, we only report the evaluation results for TransE and HolE. When considering the KGE algorithms, TransE's performance is consistently better across metrics, compared to HolE's performance. However, it is interesting to note that HolE significantly outperforms TransE for some classes/relations. When considering the evaluation metrics, it is evident that the categorization measure and semantic transitional distance are able to capture the quality of type semantics and relational semantics, respectively. The value of the coherence measure, however, is zero for HoLE in most cases and close to zero for TransE in some cases. In our experimental setting, the poor performance with respect to the coherence measure may suggest that it may not be a good metric for evaluating KGEs in the AD domain.\nWe report preliminary results from our investigation into using KGEs for a use-case in the AD domain. More specifically, we apply KGEs for computing scene similarity. In this case, the goal is to find (sub-)scenes that are characteristically similar, using the learned KGEs. Given a set of scene pairs, we choose the pair with the highest cosine similarity as the most similar. Figure FIGREF15 shows an illustration of the two most similar sub-scenes, when the list of pairs include sub-scenes from different scenes. An interesting observation is that the black string of objects in sub-scene (a) are Barriers (a Static Object), and the orange string of objects in sub-scene (b) are Stopped Cars. This example suggests that the KGE-based approach could identify sub-scenes that share similar characteristics even though the sub-scenes are visually dissimilar.\nWe presented an investigation of using KGEs for AD context understanding, along with an evaluation of the intrinsic quality of KGEs. The evaluation suggests that KGEs are specifically able to capture the semantic properties of a scene knowledge graph (e.g., isParticipantOf relation between objects and events). More generally, KGE algorithms are capable of translating semantic knowledge, such as type and relational semantics to KGEs. When considering the different KGE algorithms, we report that the transitional distance-based algorithm, TransE, shows consistent performance across multiple quantitative KGE-quality metrics. Our evaluation further suggests that some quality metrics currently in use, such as the coherence measure, may not be effective in measuring the quality of the type semantics from KGEs, in the AD domain. Finally, in applying the learned KGEs to a use-case of importance in the AD domain, we shed some light on the effectiveness of leveraging KGEs in capturing AD scene similarity.\nWe suggest neuro-symbolic fusion as one solution and, indeed, our results show that our embedding space preserves the semantic properties of the conceptual elements that make up visual scenes.",

Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge of two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.\n\nThe United States has control over fourteen territories. Five of them (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands) have a permanent, nonmilitary population, while nine of them (the United States Minor Outlying Islands) do not. With the exception of Navassa Island, Puerto Rico, and the U.S. Virgin Islands, which are located in the Caribbean, all territories are located in the Pacific Ocean. One territory, Palmyra Atoll, is considered to be incorporated, meaning the full body of the Constitution has been applied to it; the other territories are unincorporated, meaning the Constitution does not fully apply to them. Ten territories (the Minor Outlying Islands and American Samoa) are considered to be unorganized, meaning they have not had an organic act enacted by Congress; the four other territories are organized, meaning an organic act has been enacted by Congress.

In this section, we describe these data sets and describe a few of their differences.\nMiniMayoSRS: The MayoSRS, developed by PakhomovPMMRC10, consists of 101 clinical term pairs whose relatedness was determined by nine medical coders and three physicians from the Mayo Clinic. The relatedness of each term pair was assessed based on a four point scale: (4.0) practically synonymous, (3.0) related, (2.0) marginally related and (1.0) unrelated. MiniMayoSRS is a subset of the MayoSRS and consists of 30 term pairs on which a higher inter–annotator agreement was achieved. The average correlation between physicians is 0.68. The average correlation between medical coders is 0.78. We evaluate our method on the mean of the physician scores, and the mean of the coders scores in this subset in the same manner as reported by PedersenPPC07.\nUMNSRS: The University of Minnesota Semantic Relatedness Set (UMNSRS) was developed by PakhomovMALPM10, and consists of 725 clinical term pairs whose semantic similarity and relatedness was determined independently by four medical residents from the University of Minnesota Medical School. The similarity and relatedness of each term pair was annotated based on a continuous scale by having the resident touch a bar on a touch sensitive computer screen to indicate the degree of similarity or relatedness.

To maintain quality of service, users are transferred to human representatives when their conversations with an intelligent virtual assistant (IVA) fail to progress. These transfers are known as escalations. We apply Han to such conversations in a sequential manner by feeding each user turn to Han as they occur, to determine if the conversation should escalate. If so, the user will be transferred to a live chat representative to continue the conversation. To help the human representative quickly determine the cause of the escalation, we generate a visualization of the user's turns using the attention weights to highlight the turns influential in the escalation decision. This helps the representative quickly scan the conversation history and determine the best course of action based on problematic turns.\nOur application requires that the visualizations be generated in real-time at the point of escalation. The user must wait for the human representative to review the IVA chat history and resume the failed task. Therefore, we seek visualization methods that do not add significant latency to the escalation transfer. Using the attention weights for turn influence is fast as they were already computed at the time of classification. However, these weights will not generate useful visualizations for the representatives when their values are similar across all turns (see Han Weight in Table TABREF1 ). To overcome this problem, we develop a visualization method to be applied in the instances where the attention weights are uniform. Our method produces informative visuals for determining influential samples in a sequence by observing the changes in sample importance over the cumulative sequence (see Our Weight in Table TABREF1 ). Note that we present a technique that only serves to resolve situations when the existing attention weights are ambiguous; we are not developing a new attention mechanism, and, as our method is external, it does not require any changes to the existing model to apply.\nWe apply Han to such conversations in a sequential manner by feeding each user turn to Han as they occur, to determine if the conversation should escalate.

        "question": "How many BlEU scores does their model better than previous methods for the subword-level decoding?",
        "answer": "3.6 BLEU scores.",
        "evidence": "Speech-to-Text translation (ST) is essential for a wide range of scenarios: for example in emergency calls, where agents have to respond emergent requests in a foreign language BIBREF0; or in online courses, where audiences and speakers use different languages BIBREF1. To tackle this problem, existing approaches can be categorized into cascaded method BIBREF2, BIBREF3, where a machine translation (MT) model translates outputs of an automatic speech recognition (ASR) system into target language, and end-to-end method BIBREF4, BIBREF5, where a single model learns acoustic frames to target word sequence mappings in one step towards the final objective of interest. Although the cascaded model remains the dominant approach due to its better performance, the end-to-end method becomes more and more popular because it has lower latency by avoiding inferences with two models and rectifies the error propagation in theory.\nSince it is hard to obtain a large-scale ST dataset, multi-task learning BIBREF5, BIBREF6 and pre-training techniques BIBREF7 have been applied to end-to-end ST model to leverage large-scale datasets of ASR and MT. A common practice is to pre-train two encoder-decoder models for ASR and MT respectively, and then initialize the ST model with the encoder of the ASR model and the decoder of the MT model. Subsequently, the ST model is optimized with the multi-task learning by weighing the losses of ASR, MT, and ST. This approach, however, causes a huge gap between pre-training and fine-tuning, which are summarized into three folds:\nSubnet Waste: The ST system just reuses the ASR encoder and the MT decoder, while discards other pre-trained subnets, such as the MT encoder. Consequently, valuable semantic information captured by the MT encoder cannot be inherited by the final ST system.\nRole Mismatch: The speech encoder plays different roles in pre-training and fine-tuning. The encoder is a pure acoustic model in pre-training, while it has to extract semantic and linguistic features additionally in fine-tuning, which significantly increases the learning difficulty.\nNon-pre-trained Attention Module: Previous work BIBREF6 trains attention modules for ASR, MT and ST respectively, hence, the attention module of ST does not benefit from the pre-training.\nTo address these issues, we propose a Tandem Connectionist Encoding Network (TCEN), which is able to reuse all subnets in pre-training, keep the roles of subnets consistent, and pre-train the attention module. Concretely, the TCEN consists of three components, a speech encoder, a text encoder, and a target text decoder. Different from the previous work that pre-trains an encoder-decoder based ASR model, we only pre-train an ASR encoder by optimizing the Connectionist Temporal Classification (CTC) BIBREF8 objective function. In this way, the additional decoder of ASR is not required while keeping the ability to read acoustic features into the source language space by the speech encoder. Besides, the text encoder and decoder can be pre-trained on a large MT dataset. After that, we employ common used multi-task learning method to jointly learn ASR, MT and ST tasks.\nCompared to prior works, the encoder of TCEN is a concatenation of an ASR encoder and an MT encoder and our model does not have an ASR decoder, so the subnet waste issue is solved. Furthermore, the two encoders work at tandem, disentangling acoustic feature extraction and linguistic feature extraction, ensuring the role consistency between pre-training and fine-tuning. Moreover, we reuse the pre-trained MT attention module in ST, so we can leverage the alignment information learned in pre-training.\nSince the text encoder consumes word embeddings of plausible texts in MT task but uses speech encoder outputs in ST task, another question is how one guarantees the speech encoder outputs are consistent with the word embeddings. We further modify our model to achieve semantic consistency and length consistency. Specifically, (1) the projection matrix at the CTC classification layer for ASR is shared with the word embedding matrix, ensuring that they are mapped to the same latent space, and (2) the length of the speech encoder output is proportional to the length of the input frame, so it is much longer than a natural sentence. To bridge the length gap, source sentences in MT are lengthened by adding word repetitions and blank tokens to mimic the CTC output sequences.\nWe conduct comprehensive experiments on the IWSLT18 speech translation benchmark BIBREF1, demonstrating the effectiveness of each component. Our model is significantly better than previous methods by 3.6 and 2.2 BLEU scores for the subword-level decoding and character-level decoding strategies, respectively.\nOur contributions are three-folds: 1) we shed light on why previous ST models cannot sufficiently utilize the knowledge learned from the pre-training process; 2) we propose a new ST model, which alleviates shortcomings in existing methods; and 3) we empirically evaluate the proposed model on a large-scale public dataset.\nOur model is significantly better than previous methods by 3.6 and 2.2 BLEU scores for the subword-level decoding and character-level decoding strategies, respectively.",

        "answer": "One class which operates purely on triples like RESCAL, TRANSE, DISTMULT, TRANSD, COMPLEX, CONVE and the second class which seeks to incorporate additional information (like multi-hops).",
        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nMost knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL (Nickel et al., 2011), TRANSE (Bordes et al., 2013), DISTMULT (Yang et al., 2015), TRANSD (Ji et al., 2015), COMPLEX (Trouillon et al., 2016), CONVE (Dettmers et al., 2018) and the second class which seeks to incorporate additional information (like multi-hops) (Wang et al., 2017).",

        "answer": "The ratio of the number of tweets correctly classified to a given class over the total number of tweets classified to that class.",
        "evidence": "We now present the most interesting results from our experiments. For the evaluation we used standard metrics for classification accuracy, suitable for studying problems such as sentiment analysis. In particular we used Precision and Recall, with the former calculated as the ratio of the number of tweets correctly classified to a given class over the total number of tweets classified to that class, while the latter measures the ratio of messages correctly classified to a given class over the number of messages from that class. Additionally, the F-score is the harmonic mean of precision and recall, expressed as INLINEFORM0 . For our particular case with three classes, P, R and F are computed for each class separately, with the final F value derived as the weighted mean of the separate INLINEFORM1 -scores: INLINEFORM2 ; recall that INLINEFORM3 , INLINEFORM4 and INLINEFORM5 . The results are shown in Table TABREF24 , along with the reported results from state of the art approaches proposed by other researchers in the field. Note that the performance numbers P,R and F of the other state of the art approaches are based on the authors' reported data in the cited works. Additionally, we report the performance of each individual LSTM classifier as if used alone over the same data (that is, without the ensemble logic). The F-score for our proposed approaches shown in the last column, is the weighted average value over the 3 classes (Neutral,Sexism,Racism). Moreover, all the reported values are average values produced for a number of runs of the same tested scheme over the same data. Figure FIGREF23 shows the F-Score as a function of the number of training samples for each ensemble of classifiers. We clearly see that the models converge. For the final run the F-score has standard deviation value not larger than 0.001, for all classifiers.\nAs can be seen in Table TABREF24 , the work by BIBREF12 , in which character n-grams and gender information were used as features, obtained the quite low F-score of INLINEFORM0 . Later work by the same author BIBREF5 investigated the impact of the experience of the annotator in the performance, but still obtaining a lower F-score than ours. Furthermore, while the first part of the two step classification BIBREF16 performs quite well (reported an F-score of 0.9520), it falls short in detecting the particular class the abusive text belongs to. Finally, we observe that applying a simple LSTM classification with no use of additional features (denoted `single classifier (i)' in Table TABREF24 ), achieves an F-score that is below 0.93, something that is in line with other researchers in the field, see BIBREF15 .\nVery interestingly, the incorporation of features related to user's behaviour into the classification has provided a significant increase in the performance vs. using the textual content alone, INLINEFORM0 vs. INLINEFORM1 .\nAnother interesting finding is the observed performance improvement by using an ensemble instead of a single classifier; some ensembles outperform the best single classifier. Furthermore, the NRS classifier, which produces the best score in relation to other single classifiers, is the one included in the best performing ensemble.\nIn comparison to the approach by BIBREF13 , which focuses on various classes of Sexism, the results show that our deep learning model is doing better as far as detecting Sexism in general, outperforming the FastText algorithm they include in their experiments (F=0.87). The inferiority of FastText over LSTM is also reported in the work by BIBREF15 , as well as being inferior over CNN in, BIBREF16 . In general, through our ensemble schemes is confirmed that deep learning can outperform any NLP-based approaches known so far in the task of abusive language detection.\nWe also present the performance of each of the tested models per class label in Table TABREF25 . Results by other researchers have not been included, as these figures are not reported in the existing literature. As can be seen, sexism is quite easy to classify in hate-speech, while racism seems to be harder; similar results were reported by BIBREF7 . This result is consistent across all ensembles.\nFor completion, the confusion matrices of the best performing approach that employs 3 classifiers (ensemble viii) as well as of the ensemble of the 5 classifiers (xi), are provided in Table TABREF26 . The presented values is the sum over multiple runs.\nThe code and results associated with this paper will be available on-line soon at: https://github.com/gpitsilis/hate-speech/\nFor the evaluation we used standard metrics for classification accuracy, suitable for studying problems such as sentiment analysis.

Typically as the interest rate go up, the existing bonds that were sold previously at a certain maturity and coupon, now stands devalued as investors can get a newer bond for higher interest payments.  Similarly during inflation as Fed tries to control inflation by raising interest rates it has the inverse effect on bond prices. It is important to note that not all bonds react the same way to interest rates. For example, short term interest rate bonds may feel the impact almost immediately while long term bonds may have a gradual but likely to see more impactful price change.

        "evidence": "NLG is the process of automatically generating coherent NL text from non-linguistic data BIBREF0. Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans.

        "answer": "After training text embedding, they analyse a subset of 3229 records reported from St Mary’s Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nFirst, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used).  We then analyse a subset of 3229 records reported from St Mary’s Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content.",

The equations are display equations that were enumerated in the LaTeX version of the articles. Unlike inline equations, which in many instances represent variables with general meaning (e.g. INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , etc.) and even numerical values, display equations typically represent mathematical concepts with more specific semantics. For the empirical study we used a random subset of 2k singletons from the total collection, along with all equations that occur more than once. For the qualitative analysis, we used all equations.\nWe extracted words by tokenizing articles using the NLTK package BIBREF12 and restricted the vocabulary to noun phrases and adjectives.

Two of the most common political event datasets were the World Event Interaction Survey (WEIS) and the Conflict and Peace Data Bank (COPDAB) BIBREF0 , BIBREF1 . These two datasets were eventually replaced by the projects created by Philip Schrodt and various collaborators. In general, these projects were marked by the use of the Conflict and Mediation Event Observations (CAMEO) coding ontology and automated, machine-coding rather than human coding BIBREF2 , BIBREF3 . The CAMEO ontology is made up of 20 “top-level” categories that encompass actions such as “Make Statement” or “Protest”, and contains over 200 total event classifications. This ontology has served as the basis for most of the modern event datasets such as the Integrated Crisis Early Warning System (ICEWS) BIBREF4 , the Global Database of Events, Language, and Tone (GDELT), and the Phoenix dataset presented in this paper.\nThis type of data can prove highly useful for many types of studies. Since this type of data is inherently atomic, each observation is a record of a single event between a source and a target, it provides a disaggregated view of political events. This means that the data can be used to examine interactions below the usual monthly or yearly levels of aggregation. This approach can be used in a manner consistent with traditional hypothesis testing that is the norm in political science BIBREF5 , BIBREF6 , BIBREF7 . Additionally, event data has proven useful in forecasting models of conflict since the finer time resolution allows analysts to gain better leverage over the prediction problem than is possible when using more highly aggregated data BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . Finally, the advent of daily-updated event data has led to many novel uses such as watchboarding or dashboarding. The goal in these situations is to provide an easy to understand interface that analysts can use to quickly monitor ongoing or emerging situations around the world. These applications provide a new frontier for event data that has not been considered much until this point.\nThe status quo of TABARI-generated, CAMEO-coded event data, which was established in the early 2000s, has remained with little change. BIBREF12 outlined many potential advances in the generation of political event data. These advances are things such as realtime processing of news stories, the incorporation of open-source natural language processing (NLP) software, and enhancements in the automated coding structure. Two publicly-available datasets, GDELT and ICEWS, have each attempted to implement some, or all, of these changes in their respective data-generating pipelines. In terms of goals, the ICEWS project seems closest to sharing the vision of the Phoenix dataset. A more in-depth comparison of Phoenix and ICEWS is presented in a later section.

        "question": "Explain the difference between rhotic and non-rhotic dialects of English.",
        "evidence": "Rhoticity in English is the pronunciation of the historical rhotic consonant /r/ by English speakers. The presence or absence of rhoticity is one of the most prominent distinctions by which varieties of English can be classified. In rhotic varieties, the historical English /r/ sound is preserved in all pronunciation contexts. In non-rhotic varieties, speakers no longer pronounce /r/ in postvocalic environments—that is, when it is immediately after a vowel and not followed by another vowel. For example, in isolation, a rhotic English speaker pronounces the words hard and butter as /ˈhɑːrd/ and /ˈbʌtər/, whereas a non-rhotic speaker \"drops\" or \"deletes\" the /r/ sound, pronouncing them as /ˈhɑːd/ and /ˈbʌtə/. When an r is at the end of a word but the next word begins with a vowel, as in the phrase \"better apples\", most non-rhotic speakers will pronounce the /r/ in that position (the linking R), since it is followed by a vowel in this case.\n\nThe rhotic varieties of English include the dialects of South West England, Scotland, Ireland, and most of the United States and Canada. The non-rhotic varieties include most of the dialects of modern England, Wales, Australia, New Zealand, and South Africa. In some varieties, such as those of some parts of the southern and northeastern United States, rhoticity is a sociolinguistic variable: postvocalic r is deleted depending on an array of social factors, such as being more correlated today with lower socioeconomic status, greater age, certain ethnic identities, and less formal speaking contexts.\n\nEvidence from written documents suggests that loss of postvocalic /r/ began sporadically during the mid-15th century, although these /r/-less spellings were uncommon and were restricted to private documents, especially ones written by women in England. In the mid-18th century, postvocalic /r/ was still pronounced in most environments, but by the 1740s to 1770s it was often deleted entirely, especially after low vowels. By the early 19th century, the southern British standard was fully transformed into a non-rhotic variety, though some variation persisted as late as the 1870s.\n\nIn the 18th century (and possibly 17th century), the loss of postvocalic /r/ in British English influenced southern and eastern American port cities with close connections to Britain, causing their upper-class pronunciation to become non-rhotic while the rest of the United States remained rhotic. Non-rhotic pronunciation continued to influence American prestige speech until the 1860s, when the American Civil War began to shift America's centers of wealth and political power to rhotic areas with fewer cultural connections to the old colonial and British elites. In the United States, non-rhotic speech continued to hold some level of prestige up until the mid-20th century, but rhotic speech in particular became prestigious nationwide rapidly after the Second World War, reflected in the national standard of radio and television since the mid-20th century embracing historical /r/.",

Several QA approaches were proposed in the literature for the open domain BIBREF16 , BIBREF17 and the medical domain BIBREF18 , BIBREF19 , BIBREF20 . A variety of methods were developed for question analysis, focus (topic) recognition and question type identification BIBREF21 , BIBREF22 , BIBREF23 , BIBREF24 . Similarly, many different approaches tackled document or passage retrieval and answer selection and (re)ranking BIBREF25 , BIBREF26 , BIBREF27 .\nAn alternative approach consists in finding similar questions or FAQs that are already answered BIBREF28 , BIBREF29 . One of the earliest question answering systems based on finding similar questions and re-using the existing answers was FAQ FINDER BIBREF30 . Another system that complements the existing Q&A services of NetWellness is SimQ BIBREF2 , which allows retrieval of similar web-based consumer health questions. SimQ uses syntactic and semantic features to compute similarity between questions, and UMLS BIBREF31 as a standardized semantic knowledge source. The system achieves 72.2% precision, 78.0% recall and 75.0% F-score on NetWellness questions. However, the method was evaluated only on one question similarity dataset, and the retrieved answers were not evaluated.\nThe aim of the medical task at TREC 2017 LiveQA was to develop techniques for answering complex questions such as consumer health questions, as well as to identify relevant answer sources that can comply with the sensitivity of medical information retrieval.\nThe CMU-OAQA system BIBREF32 achieved the best performance of 0.637 average score on the medical task by using an attentional encoder-decoder model for paraphrase identification and answer ranking. The Quora question-similarity dataset was used for training. The PRNA system BIBREF33 achieved the second best performance in the medical task with 0.49 average score using Wikipedia as the first answer source and Yahoo and Google searches as secondary answer sources. Each medical question was decomposed into several subquestions. To extract the answer from the selected text passage, a bi-directional attention model trained on the SQUAD dataset was used.\nDeep neural network models have been pushing the limits of performance achieved in QA related tasks using large training datasets. The results obtained by CMU-OAQA and PRNA showed that large open-domain datasets were beneficial for the medical domain. However, the best system (CMU-OAQA) relying on the same training data obtained a score of 1.139 on the LiveQA open-domain task.\nWhile this gap in performance can be explained in part by the discrepancies between the medical test questions and the open-domain questions, it also highlights the need for larger medical datasets to support deep learning approaches in dealing with the linguistic complexity of consumer health questions and the challenge of finding correct and complete answers.\nAnother technique was used by ECNU-ICA team BIBREF34 based on learning question similarity via two long short-term memory (LSTM) networks applied to obtain the semantic representations of the questions. To construct a collection of similar question pairs, they searched community question answering sites such as Yahoo! and Answers.com. In contrast, the ECNU-ICA system achieved the best performance of 1.895 in the open-domain task but an average score of only 0.402 in the medical task. As the ECNU-ICA approach also relied on a neural network for question matching, this result shows that training attention-based decoder-encoder networks on the Quora dataset generalized better to the medical domain than training LSTMs on similar questions from Yahoo! and Answers.com.\nThe CMU-LiveMedQA team BIBREF20 designed a specific system for the medical task. Using only the provided training datasets and the assumption that each question contains only one focus, the CMU-LiveMedQA system obtained an average score of 0.353. They used a convolutional neural network (CNN) model to classify a question into a restricted set of 10 question types and crawled \"relevant\" online web pages to find the answers. However, the results were lower than those achieved by the systems relying on finding similar answered questions. These results support the relevance of similar question matching for the end-to-end QA task as a new way of approaching QA instead of the classical QA approaches based on Question Analysis and Answer Retrieval.\nClassical QA systems face two main challenges related to question analysis and answer extraction.",

From Fig. we saw that within-domain and cross-domain evaluation have different optimal tuning. If we consider automating the search for a good regularisation parameter, these two final evaluation criteria correspond respectively to hyperparameter selection based on a validation set from the seen source domains, vs based on a validation set drawn from a held out source domain. The latter validation criterion corresponds to a unbiased estimator of expected cross-domain generalisation performance R E (f ), which our theorem bounds.\nSetup We performed DG evaluation on DomainBed using ERM with linear models using the same DINO features as Section 4.1. For each held out domain, we performed hyperparameter tuning with either instance-wise cross-validation (where validation folds are drawn from the same source domains used for training) or domain-wise cross-validation (where validation folds are drawn from held-out domains not seen during training).\nThe results in Table report the average accuracy across held out domains, and the average selected log C regularisation strength (See Supplementary for the full breakdown of results for each held-out domain). We can see that the domain-wise cross-validation objective leads to similar or better accuracy, and similar or smaller C value selection (i.e., stronger regularisation). This outcome is opposite to the observation made by. Given the theoretical support for our domain-wise objective, and our clear empirical outcome when freed of confounding factors such as stochasticity in neural network training, we consider our result to be decisive and attribute the different observation to the inaccuracy and stochasticity of hyperparameter tuning in neural networks.\nTable: Comparing model selection criteria using LinearSVC.

Meno begins the dialogue by asking Socrates whether virtue is taught, acquired by practice, or comes by nature. In order to determine whether virtue is teachable or not, Socrates tells Meno that they first need to determine what virtue is. When the characters speak of virtue, or rather arete, they refer to virtue in general, rather than particular virtues, such as justice or temperance. The first part of the work showcases Socratic dialectical style; Meno, unable to adequately define virtue, is reduced to confusion or aporia. Socrates suggests that they seek an adequate definition for virtue together. In response, Meno suggests that it is impossible to seek what one does not know, because one will be unable to determine whether one has found it.\n\nSocrates challenges Meno's argument, often called \"Meno's Paradox\" or the \"Learner's Paradox\", by introducing the theory of knowledge as recollection (anamnesis). As presented in the dialogue, the theory proposes that souls are immortal and know all things in a disembodied state; learning in the embodied is actually a process of recollecting that which the soul knew before it came into a body. Socrates demonstrates recollection in action by posing a mathematical puzzle to one of Meno's slaves. Subsequently, Socrates and Meno return to the question of whether virtue is teachable, employing the method of hypothesis. Near the end of the dialogue, Meno poses another famous puzzle, called \"The Meno Problem\" or \"The Value Problem for Knowledge\", which questions why knowledge is valued more highly than true belief. In response, Socrates provides a famous and somewhat enigmatic distinction between knowledge and true belief.",

A sloop is a monohull sailboat with a single- rig mast supporting a main sail and and headsail. These are great boats to learn sailing on as their simple, easy to handle, and have great wind performance. \n\nA cutter at first look is similar to a sloop in that it also has a single mast positioned near the middle of the boat. However, a cutter uses two headsails, instead of a mainsail and headsail, and generally includes a bowsprit. This allows the boat to have better stability in rough weather due to the headsails providing a lower center of gravity. The complex rigging makes this boat more challenging to sail than the sloop, but provides an excellent option for an experienced sailor. \n\nA ketch has two masts. The main mast in the front stands taller than the mizzen mast behind it. The mizzen mast stands forward of the rudder post. The ketch has smaller sails and shorter masts. While this makes them slower than a sloop, they are very controllable in rough weather which makes them excellent boats for off shore sailing.",

In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the \"energy currency\" of cells.\n\nIn plants, algae and cyanobacteria, sugars are synthesized by a subsequent sequence of light-independent reactions called the Calvin cycle. In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose bisphosphate (RuBP). Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose. In other bacteria, different mechanisms such as the reverse Krebs cycle are used to achieve the same end.",

        "question": "Why do the authors propose a novel Dual-channel Word Embedding (DWE) model?",
        "answer": "To realize the joint learning of sequential and spatial information in characters.",
        "evidence": "Word embeddings are fixed-length vector representations for words BIBREF0 , BIBREF1 . In recent years, the morphology of words is drawing more and more attention BIBREF2 , especially for Chinese whose writing system is based on logograms.\nUTF8gbsn With the gradual exploration of the semantic features of Chinese, scholars have found that not only words and characters are important semantic carriers, but also stroke feature of Chinese characters is crucial for inferring semantics BIBREF3 . Actually, a Chinese word usually consists of several characters, and each character can be further decomposed into a stroke sequence which is certain and changeless, and this kind of stroke sequence is very similar to the construction of English words. In Chinese, a particular sequence of strokes can reflect the inherent semantics. As shown in the upper half of Figure FIGREF3 , the Chinese character “驾\" (drive) can be decomposed into a sequence of eight strokes, where the last three strokes together correspond to a root character “马\" (horse) similar to the root “clar\" of English word “declare\" and “clarify\".\nMoreover, Chinese is a language originated from Oracle Bone Inscriptions (a kind of hieroglyphics). Its character glyphs have a spatial structure similar to graphs which can convey abundant semantics BIBREF4 . Additionally, the critical reason why Chinese characters are so rich in morphological information is that they are composed of basic strokes in a 2-D spatial order. However, different spatial configurations of strokes may lead to different semantics. As shown in the lower half of Figure 1, three Chinese characters “入\" (enter), “八\" (eight) and “人\" (man) share exactly a common stroke sequence, but they have completely different semantics because of their different spatial configurations.\nIn addition, some biological investigations have confirmed that there are actually two processing channels for Chinese language. Specifically, Chinese readers not only activate the left brain which is a dominant hemisphere in processing alphabetic languages BIBREF5 , BIBREF6 , BIBREF7 , but also activate the areas of the right brain that are responsible for image processing and spatial information at the same time BIBREF8 . Therefore, we argue that the morphological information of characters in Chinese consists of two parts, i.e., the sequential information hidden in root-like strokes order, and the spatial information hidden in graph-like character glyphs. Along this line, we propose a novel Dual-channel Word Embedding (DWE) model for Chinese to realize the joint learning of sequential and spatial information in characters. Finally, we evaluate DWE on two representative tasks, where the experimental results exactly validate the superiority of DWE in capturing the morphological information of Chinese.\nAlong this line, we propose a novel Dual-channel Word Embedding (DWE) model for Chinese to realize the joint learning of sequential and spatial information in characters.",

        "answer": "It is a novel and compact model, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time.",

        "evidence": "Despite the similarity of the Open IE paradigm, not every extracted tuple is a suitable proposition for a concept map. To reduce the effort in the subsequent steps, we therefore want to filter out unsuitable ones. A tuple is suitable if it (1) is a correct extraction, (2) is meaningful without any context and (3) has arguments that represent proper concepts. We created a guideline explaining when to label a tuple as suitable for a concept map and performed a small annotation study. Three annotators independently labeled 500 randomly sampled tuples. The agreement was 82% ( INLINEFORM0 ). We found tuples to be unsuitable mostly because they had unresolvable pronouns, conflicting with (2), or arguments that were full clauses or propositions, conflicting with (3), while (1) was mostly taken care of by the confidence filtering in § SECREF21 .\nDue to the high number of tuples we decided to automate the filtering step. We trained a linear SVM on the majority voted annotations. As features, we used the extraction confidence, length of arguments and relations as well as part-of-speech tags, among others. To ensure that the automatic classification does not remove suitable propositions, we tuned the classifier to avoid false negatives. In particular, we introduced class weights, improving precision on the negative class at the cost of a higher fraction of positive classifications. Additionally, we manually verified a certain number of the most uncertain negative classifications to further improve performance. When 20% of the classifications are manually verified and corrected, we found that our model trained on 350 labeled instances achieves 93% precision on negative classifications on the unseen 150 instances. We found this to be a reasonable trade-off of automation and data quality and applied the model to the full dataset.\nThe classifier filtered out 43% of the propositions, leaving 1622 per topic. We manually examined the 17k least confident negative classifications and corrected 955 of them. We also corrected positive classifications for certain types of tuples for which we knew the classifier to be imprecise. Finally, each topic was left with an average of 1554 propositions (47k in total).\nA tuple is suitable if it (1) is a correct extraction, (2) is meaningful without any context and (3) has arguments that represent proper concepts.",

        "evidence": "Prior work have shown that contextual information could be useful for SF. They utilize contextual information either in word level representation (i.e., via contextualize embedding e.g., BERT BIBREF0) or in the model computation graph (e.g., concatenating the context feature to the word feature BIBREF1). However, such methods fail to capture the explicit dependence between the context of the word and its label. Moreover, such limited use of contextual information (i.e., concatenation of the feature vector and context vector) in the model cannot model the interaction between the word representation and its context. In order to alleviate these issues, in this work, we propose a novel model to explicitly increase the predictability of the word label using its context and increasing the interactivity between word representations and its context. More specifically, in our model we use the context of the word to predict its label and by doing so our model learns label-aware context for each word in the sentence. In order to improve the interactivity between the word representation and its context, we increase the mutual information between the word representations and its context. In addition to these contributions, we also propose an auxiliary task to predict which labels are expressed in a given sentence. Our model is trained in a mutli-tasking framework. Our experiments on a SF dataset for identifying semantic concepts from natural language request to edit an image show the superiority of our model compared to previous baselines. Our model achieves the state-of-the-art results on the benchmark dataset by improving the F1 score by almost 2%, which corresponds to a 12.3% error rate reduction.\nMore specifically, in our model we use the context of the word to predict its label and by doing so our model learns label-aware context for each word in the sentence.

We participated in Task B of the challenge which is concerned with biomedical QA. More specifically, our system participated in Task B, Phase B: Given a question and gold-standard snippets (i.e., pieces of text that contain the answer(s) to the question), the system is asked to return a list of answer candidates.\nThe fifth BioASQ challenge is taking place at the time of writing. Five batches of 100 questions each were released every two weeks. Participating systems have 24 hours to submit their results. At the time of writing, all batches had been released.\nThe questions are categorized into different question types: factoid, list, summary and yes/no. Our work concentrates on answering factoid and list questions. For factoid questions, the system's responses are interpreted as a ranked list of answer candidates. They are evaluated using mean-reciprocal rank (MRR). For list questions, the system's responses are interpreted as a set of answers to the list question. Precision and recall are computed by comparing the given answers to the gold-standard answers. F1 score, i.e., the harmonic mean of precision and recall, is used as the official evaluation measure .\nMost existing biomedical QA systems employ a traditional QA pipeline, similar in structure to the baseline system by weissenborn2013answering. They consist of several discrete steps, e.g., named-entity recognition, question classification, and candidate answer scoring. These systems require a large amount of resources and feature engineering that is specific to the biomedical domain. For example, OAQA BIBREF1 , which has been very successful in last year's challenge, uses a biomedical parser, entity tagger and a thesaurus to retrieve synonyms.\nOur system, on the other hand, is based on a neural network QA architecture that is trained end-to-end on the target task. We build upon FastQA BIBREF2 , an extractive factoid QA system which achieves state-of-the-art results on QA benchmarks that provide large amounts of training data. For example, SQuAD BIBREF3 provides a dataset of $\\approx 100,000$ questions on Wikipedia articles. Our approach is to train FastQA (with some extensions) on the SQuAD dataset and then fine-tune the model parameters on the BioASQ training set.\nNote that by using an extractive QA network as our central component, we restrict our system's responses to substrings in the provided snippets. This also implies that the network will not be able to answer yes/no questions.

In row (f), multi-BERT is fine-tuned on English but tested on Chinese, which achieves competitive performance compared with QANet trained on Chinese. We also find that multi-BERT trained on English has relatively lower EM compared with the model with comparable F1 scores. This shows that the model learned with zero-shot can roughly identify the answer spans in context but less accurate. In row (c), we fine-tuned a BERT model pre-trained on English monolingual corpus (English BERT) on Chinese RC training data directly by appending fastText-initialized Chinese word embeddings to the original word embeddings of English-BERT. Its F1 score is even lower than that of zero-shot transferring multi-BERT (rows (c) v.s. (e)).

Candidates should look for jobs that involve building best-in-class business skills (such as working at Goldman Sachs or McKinsey) or involve leading large groups of people to accomplish important and challenging projects.  One piece of advice is to look at the resumes of successful applicants and see what types of roles they had pre-MBA.\n\nIn addition to having excellent work experience on your resume, it is equally important to have a track record of success at those jobs.  To evaluate track record of strong work performance, business schools require 2-3 letters of recommendations.  It is critical for these recommendations to be highly positive, and any lack of enthusiasm can be an instant red flag for admissions officers.\n\nIn terms of quantitative factors, Harvard, Stanford and Wharton have high average GMAT scores.  Harvard's median GMAT score, for example, was 730 out of 800 for the class of 2024.  Be sure to invest time in preparing for the GMAT, as candidates can significantly increase scores through consistent and dedicated practice.\n\nAdditionally, the essays candidates submit are very important.  The goal of a business school admissions officer to is find candidates who are likely to reach senior executive leadership or other impactful roles in society.  Your essay would ideally reflect a) an aspirational but attainable goal to reach a high impact position, and b) a clear path to get from where you currently are to your long-term goals, including a logical short-term goal immediate post-business school.\n\nSome candidates opt to hire an MBA admissions consultant, which typically costs between $2000-3000 per application.  Consider whether an MBA admissions consultant would be valuable for your process, and if so, be sure to evaluate several by having free upfront consultations.",

        "evidence": "A continuous seven day cycle that runs throughout history, paying no attention whatsoever to the phases of the moon and having a fixed day of rest, was most likely first practised in Judaism, dated to the 6th century BC at the latest.\n\nIn Ancient Rome (753 BC–476 AD), every eight days there was a nundinae. It was a market day, during which children were exempted from school and agricultural workers stopped work in the field and came to the city to sell the produce of their labor or to practice religious rites.[citation needed]\n\nThe French Revolutionary Calendar (1793–1805) had ten-day weeks (called décades) and allowed décadi, one out of the ten days, as a leisure day. From 1929 to 1940, the Soviet Union utilized a calendar with five and six-day work weeks, with a rest day assigned to a worker either with a colour or number.\n\nIn cultures with a four-day workweek, the three Sabbaths derive from the culture's main religious tradition: Friday (Muslim), Saturday (Jewish, Adventist), and Sunday (Christian).\n\nThe present-day concept of the relatively longer 'week-end' first arose in the industrial north of Britain in the early 19th century and was originally a voluntary arrangement between factory owners and workers allowing Saturday afternoon off starting at 2 pm on the basis that staff would be available for work sober and refreshed on Monday morning. The Oxford English Dictionary traces the first use of the term weekend to the British magazine Notes and Queries in 1879.\n\nIn 1908, the first five-day workweek in the United States was instituted by a New England cotton mill so that Jewish workers would not have to work on the Sabbath from sundown Friday to sundown Saturday. In 1926, Henry Ford began shutting down his automotive factories for all of Saturday and Sunday, due to pressures stemming from the October Revolution,[citation needed] which witnessed the ruling class persecuted for not giving the laborers dignifying conditions. In 1929, the Amalgamated Clothing Workers of America was the first union to demand and receive a five-day workweek. The rest of the United States slowly followed, but it was not until 1940, when a provision of the 1938 Fair Labor Standards Act mandating a maximum 40-hour workweek went into effect, that the two-day weekend was adopted nationwide.\n\nOver the succeeding decades, particularly in the 1940s to 1960s, an increasing number of countries adopted either a Friday–Saturday or a Saturday–Sunday weekend to harmonize with international markets. A series of workweek reforms in the mid-to-late 2000s and early 2010s brought much of the Arab World in synchronization with the majority of countries around the world, in terms of working hours, the length of the workweek, and the days of the weekend. The International Labour Organization (ILO) currently defines a workweek exceeding 48 hours as excessive. A 2007 study by the ILO found that at least 614.2 million people around the world were working excessive hours.",

        "answer": "Based on your feedback, we have updated our paper (Sec. 3.2 (S2) and (S3)) with additional justifications and intuition behind the graph features that we leverage during the signature construction step (degree and eigenvector centrality). We chose weighted degree centrality to efficiently capture (1) the weights that are learned in each layer of the NN at the node level (filter or neuron), which are the most important aspect of the training process; and (2) the change of the learned weights during the training process of NN over time (in the proposed time-evolving graph representation). Moreover, we use the node degrees to model the NN structure since they have been found to be effective in capturing the structural roles of nodes and a key notion for structural node embedding [1]. We note that we show the difference in how the degree-based signatures change during the training process for low accuracy NNs vs. high accuracy ones in Figure-7-9 in the appendix. Eigenvector centrality is used to capture the highly influential nodes in a graph; in our case, the nodes correspond to filters of convolutional layers and neurons of fully connected layers. Additionally, eigenvector centrality has been used for detecting communities [2] or clusters [3], and thus provides structural information about the clusterability of the NN. Clusters or communities are central for network analysis and provide complementary information compared to the simpler and more efficient-to-compute degree centrality. Our hypothesis was that tracking changes in the eigenvector centrality (or node influence or clustering-related information) over time could provide complementary insights into the structural changes of the NN during training that may correlate with high or low performance.",
        "evidence": "A key objective of our work is to test whether the introduced graph representation of NNs is informative for predicting the performance of NNs. Next, we describe the steps of our proposed framework for solving Problem 1, namely performance prediction from the NN training dynamics.\nAs shown in Fig., our method consists of four steps: (S1) generation of a temporal graph for the training phase of each NN; (S2) extraction of node features; (S3) construction of a feature-based graph signature that captures the NN dynamics; (S4) prediction of NN performance by training a classifier or regressor on the constructed signatures. We describe these steps in more detail next.\n(S1) Graph generation. The first step involves converting the training process of each input NN into a time-evolving graph. Each NN N tri ∈ N , is represented as a series of checkpoints saved for t training epochs. Based on these checkpoints and the graph representation approaches for fc and conv layers presented in 2.2, 3.1 and 2.3, we first convert the τ th NN checkpoint into weighted graph G (τ ) i at timestamp/epoch τ . We note that although our proposed graph representation involves node features, our framework does not leverage them, and thus we consider the generated graphs unattributed. Therefore, each NN N tri is mapped to a time-evolving graph\nThe output of this step is a set of n time-evolving graphs {G tr1 , G tr2 , ..., G trn } corresponding to the original n NNs in N .\n(S2) Feature extraction. Next, the goal is to capture the structural dynamics of the NN training process. We aim to select graph measures that can capture changes during the training process, take into account the edge weight of graphs and can be calculated efficiently. In order to do that in an interpretable way, we extract two well-known node centralities from each snapshot of each generated time-evolving graph G i : weighted degree centrality and eigenvector centrality ( § 2.1). The weighted degree is a simple function of the learnable weight matrix W during the training phase of NN, therefore it gives us insights into the training dynamics at the node/neuron/filter level. The eigenvector centrality is an extension of the degree centrality, which captures the highly influential nodes, and has been successfully used in neuroscience to capture the dynamic changes of real neural networks (or connectomes). Eigenvector centrality can be used to capture importance and connectivity of filters/neurons (i.e., the nodes in our graph representation). Also, eigenvector centrality has been used for detecting communities or clusters, and thus provides structural information about the clusterability of the NN, which is complementary to that provided by the simpler and more efficient-to-compute degree centrality.\nOur choice of features is also guided by the inherent k-partite structure of our proposed graph representation, which cannot be represented well by several other commonly-used graph features. For example, clustering-based features (e.g., number of triangles, transitivity, clustering coefficient) and cycle-based metrics which account for closed paths in a graph are always equal to 0 for k-partite graphs. Moreover, connected component-related features (i.e., strong/weak connectivity) do not capture the learned edge weights, which are important for modeling the training dynamics of NNs. Other features (e.g., betweenness centrality) tend to be computationally expensive, and would add significant overhead compared to early stopping methods.\n(S3) Graph signature construction. In order to be able to compare NN-based graphs (with different number of nodes and edges), we summarize the structural changes in the generated time-evolving graphs at the graph level (rather than the node level, as in (S2)), and construct a statistical summary of the extracted node centralities (signature) per time-evolving graph G i . For each snapshot G (τ ) i of G i , we create a signature vector using five node feature aggregators, which were introduced in for graph similarity: median, mean, standard deviation, skewness, and kurtosis, where all but the median are moments of the corresponding distribution. Thus, G (τ ) i is mapped to a (static) signature vector s (τ ) i ∈ R 5 , representing the statistical summary of its node features (i.e., degree or eigenvector centrality) at time τ . To put more emphasis on the most recent timestamp, we can redefine the signature at time τ as the linear weighted average of the signatures up to that point,\n, or an exponential function of the previous signatures, s i ← αs\n. To obtain the temporal signature of the evolving graph G i , we aggregate the (static) signatures up to timestamp/epoch t:\n, where ⊕ denotes concatenation. We note that global features such as algebraic connectivity, modularity, and average shortest paths may be seen as alternative ways for constructing global graph signatures while circumventing the local feature extraction step (S2); however, these features fail to capture the structural changes in our proposed graph representations (they remain (near-)constant over time) and lead to poor performance.\n(S4) Performance prediction. For the last step of performance prediction, we consider two tasks: • Classification: We train a classifier (e.g., SVM, MLP) using the training graphs {G tr1 , G tr2 , ..., G trn } represented by their temporal signatures {s t tr1 , s t tr2 , ..., s t trn }, and their corresponding accuracies A = {α 1 , α 2 , . . . , α n } mapped to labels L = {l 1 , l 2 , . . . , l n } (e.g., high/low accuracy) based on some threshold. Any test NN instance is then classified using the trained classifier.\n• Linear regression: We perform linear regression to estimate the actual accuracy value α tst of a new test instance N tst based on its signature obtained through steps (S1)-(S3).\n(S2) Feature extraction. Next, the goal is to capture the structural dynamics of the NN training process. We aim to select graph measures that can capture changes during the training process, take into account the edge weight of graphs and can be calculated efficiently. In order to do that in an interpretable way, we extract two well-known node centralities from each snapshot of each generated time-evolving graph Gi : weighted degree centrality and eigenvector centrality (§ 2.1). The weighted degree is a simple function of the learnable weight matrix W during the training phase of NN, therefore it gives us insights into the training dynamics at the node/neuron/filter level. The eigenvector centrality is an extension of the degree centrality, which captures the highly influential nodes, and has been successfully used in neuroscience to capture the dynamic changes of real neural networks (or connectomes) (Lohmann et al., 2010). Eigenvector centrality can be used to capture importance and connectivity of filters/neurons (i.e., the nodes in our graph representation). Also, eigenvector centrality has been used for detecting communities (Newman, 2006) or clusters (Wu et al., 2013), and thus provides structural information about the clusterability of the NN, which is complementary to that provided by the simpler and more efficient-to-compute degree centrality.

For example, clustering-based features (e.g., number of triangles, transitivity, clustering coefficient) and cycle-based metrics which account for closed paths in a graph are always equal to 0 for k-partite graphs. Moreover, connected component-related features (i.e., strong/weak connectivity) do not capture the learned edge weights, which are important for modeling the training dynamics of NNs. Other features (e.g., betweenness centrality) tend to be computationally expensive, and would add significant overhead compared to early stopping methods.",

        "question": "What is a string kernel?",
        "answer": "String kernel is a technique that uses character n-grams to measure the similarity of strings",
        "evidence": "In recent years, methods based on string kernels have demonstrated remarkable performance in various text classification tasks BIBREF35 , BIBREF36 , BIBREF22 , BIBREF19 , BIBREF10 , BIBREF17 , BIBREF26 . String kernels represent a way of using information at the character level by measuring the similarity of strings through character n-grams. Lodhi et al. BIBREF35 used string kernels for document categorization, obtaining very good results. String kernels were also successfully used in authorship identification BIBREF22 . More recently, various combinations of string kernels reached state-of-the-art accuracy rates in native language identification BIBREF19 and Arabic dialect identification BIBREF17 . Interestingly, string kernels have been used in cross-domain settings without any domain adaptation, obtaining impressive results. For instance, Ionescu et al. BIBREF19 have employed string kernels in a cross-corpus (and implicitly cross-domain) native language identification experiment, improving the state-of-the-art accuracy by a remarkable INLINEFORM0 . Giménez-Pérez et al. BIBREF10 have used string kernels for single-source and multi-source polarity classification. Remarkably, they obtain state-of-the-art performance without using knowledge from the target domain, which indicates that string kernels provide robust results in the cross-domain setting without any domain adaptation. Ionescu et al. BIBREF17 obtained the best performance in the Arabic Dialect Identification Shared Task of the 2017 VarDial Evaluation Campaign BIBREF37 , with an improvement of INLINEFORM1 over the second-best method. It is important to note that the training and the test speech samples prepared for the shared task were recorded in different setups BIBREF37 , or in other words, the training and the test sets are drawn from different distributions. Different from all these recent approaches BIBREF19 , BIBREF10 , BIBREF17 , we use unlabeled data from the target domain to significantly increase the performance of string kernels in cross-domain text classification, particularly in English polarity classification.\nString kernels represent a way of using information at the character level by measuring the similarity of strings through character n-grams.",

This dataset contains Amazon product reviews of four different product domains: Books (B), DVD (D), Electronics (E), and Kitchen (K) appliances. Each review is originally associated with a rating of 1-5 stars and is encoded in 5,000 dimensional feature vectors of bag-of-words unigrams and bigrams.\nFrom this dataset, we constructed 12 binary-class cross-domain sentiment analysis tasks: B$\\rightarrow $D, B$\\rightarrow $E, B$\\rightarrow $K, D$\\rightarrow $B, D$\\rightarrow $E, D$\\rightarrow $K, E$\\rightarrow $B, E$\\rightarrow $D, E$\\rightarrow $K, K$\\rightarrow $B, K$\\rightarrow $D, K$\\rightarrow $E. Following the setting of previous works, we treated a reviews as class `1' if it was ranked up to 3 stars, and as class `2' if it was ranked 4 or 5 stars. For each task, $\\mathcal {D}_S$ consisted of 1,000 examples of each class, and $\\mathcal {D}_T$ consists of 1500 examples of class `1' and 500 examples of class `2'. In addition, since it is reasonable to assume that $\\mathcal {D}_T$ can reveal the distribution of target domain data, we controlled the target domain testing dataset to have the same class ratio as $\\mathcal {D}_T$. Using the same label assigning mechanism, we also studied model performance over different degrees of $\\rm {P}(\\rm {Y})$ shift, which was evaluated by the max value of $\\rm {P}_S(\\rm {Y}=i)/\\rm {P}_T(\\rm {Y}=i), \\forall i=1, \\cdots , L$. Please refer to Appendix C for more detail about the task design for this study.\nWe additionally constructed 12 multi-class cross-domain sentiment classification tasks. Tasks were designed to distinguish reviews of 1 or 2 stars (class 1) from those of 4 stars (class 2) and those of 5 stars (class 3). For each task, $\\mathcal {D}_S$ contained 1000 examples of each class, and $\\mathcal {D}_T$ consisted of 500 examples of class 1, 1500 examples of class 2, and 1000 examples of class 3. Similarly, we also controlled the target domain testing dataset to have the same class ratio as $\\mathcal {D}_T$.\nTable TABREF27 shows model performance on the 12 binary-class cross-domain tasks. From this table, we can obtain the following observations. First, CMD and DANN underperform the source-only model (SO) on all of the 12 tested tasks, indicating that DIRL in the studied situation will degrade the domain adaptation performance rather than improve it. This observation confirms our analysis. Second, $\\text{CMD}^{\\dagger \\dagger }$ consistently outperformed CMD and SO. This observation shows the effectiveness of our proposed method for addressing the problem of the DIRL framework in the studied situation. Similar conclusion can also be obtained by comparing performance of $\\text{DANN}^{\\dagger \\dagger }$ with that of DANN and SO. Third, $\\text{CMD}^{\\dagger }$ and $\\text{DANN}^{\\dagger }$ consistently outperformed $\\text{CMD}$ and DANN, respectively, which shows the effectiveness of the first step of our proposed method. Finally, on most of the tested tasks, $\\text{CMD}^{\\dagger \\dagger }$ and $\\text{DANN}^{\\dagger \\dagger }$ outperforms $\\text{CMD}^{\\dagger }$ and $\\text{DANN}^{\\dagger }$, respectively. Figure FIGREF35 depicts the relative improvement, e.g., $(\\text{Acc}(\\text{CMD})-\\text{Acc}(\\text{SO}))/\\text{Acc}(\\text{SO})$, of the domain adaptation methods over the SO baseline under different degrees of $\\rm {P}(\\rm {Y})$ shift, on two binary-class domain adaptation tasks (You can refer to Appendix C for results of the other models on other tasks). From the figure, we can see that the performance of CMD generally got worse as the increase of $\\rm {P}(\\rm {Y})$ shift. In contrast, our proposed model $\\text{CMD}^{\\dagger \\dagger }$ performed robustly to the varying of $\\rm {P}(\\rm {Y})$ shift degree. Moreover, it can achieve the near upbound performance characterized by $\\text{CMD}^{*}$. This again verified the effectiveness of our solution.\nThrough the experiments, we empirically studied our analysis on DIRL and the effectiveness of our proposed solution in dealing with the problem it suffered from.

However, learning fails when maximizing the CLUB objective. There is a collapse to a single mode both without and with modern Hopfield networks. After extensive experimentation, we were not able to solve this problem. While CLUB averages over the negatives, InfoLOOB uses a log-sum-exponential (LSE). The LSE avoids a collapse since the sample that is most similar to the anchor is strongly pushed away from the anchor and even away from the average. The LSE leads to a more uniform distribution of features on the hypersphere. Our observations are in agreement with the findings in “Understanding Contrastive Representation Learning through Alignment and Uniformity on the Hypersphere” (https://arxiv.org/abs/2005.10242).\nWe now write in the paper: “Contrastive Log-ratio Upper Bound (CLUB), another upper bound on the mutual information, was only used for minimizing it (Cheng et al., 2020).

Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans. The version of LD2NL used in this paper, all experimental results will be publicly available.\nAdditionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL.",

First, to make the model's prediction more explainable, we implement a path based QA model PCNet. In this model, to get candidate answers from the triplets based document for a given question. We first retrieve the an “anchor” point $arg1_i$ or $arg2_i$ in the document fact $f_i$ . These anchors are selected based on edit distance between the words in the questions and the arguments. Then we regard all arguments in the 1-hops and 2-hops fact of the anchors as answers. However, the coverage of the candidate answers can be 100% in the model. We then implement a second end-to-end neural model KVMenNet which covers all the answers but with less interpretability. Both models generate a score $f_{qa}(q, a)$ of each candidate answer.\nWe then implement a generation-based model. The motivation to design this model is that we want to associate natural language phrases with knowledge based representation. It takes semantics of a candidate answer as the input and generates a question $\\hat{q}$ . Then a paraphrasing model gives a score $f_{qg}(q,\\hat{q})$ , which is computed between the generated question $\\hat{q}$ and the original question $q$ , as the ranking score.\nWe get the final scores $S(q,a)$ used for ranking as follows. \n$$S(q,a) = \\lambda f_{qa}(q, a) + (1-\\lambda ) f_{qg}(q,\\hat{q})$$   (Eq. 7) \nMoreover, we incorporate side information from external KBs into the three models.

In this section, we recommend a set of evaluation design changes that we believe are needed for assessing human–machine parity, and will strengthen the human evaluation of MT in general.\nRecommendations ::: (R1) Choose professional translators as raters.\nIn our blind experiment (Section SECREF3), non-experts assess parity between human and machine translation where professional translators do not, indicating that the former neglect more subtle differences between different translation outputs.\nRecommendations ::: (R2) Evaluate documents, not sentences.\nWhen evaluating sentences in random order, professional translators judge machine translation more favourably as they cannot identify errors related to textual coherence and cohesion, such as different translations of the same product name. Our experiments show that using whole documents (i. e., full news articles) as unit of evaluation increases the rating gap between human and machine translation (Section SECREF4).\nRecommendations ::: (R3) Evaluate fluency in addition to adequacy.\nRaters who judge target language fluency without access to the source texts show a stronger preference for human translation than raters with access to the source texts (Sections SECREF4 and SECREF24).

On the other hand, frozen vegetables are harvested close to peak maturity and nutrition levels.\n\nUnless you have your own kitchen garden or have access to a farmers market located close to where the vegetables are actually grown, frozen is a better bet - it's fresher, more convenient and rather crucially, more easily accessible for you to improve the health quotient of your meals. It's better to eat frozen peas all through the year than be puritanical about enjoying it only during winter. Eating healthily is as much a behavior science problem as it is a nutrition science problem, and it's easier to keep frozen peas around and eat it regularly than to try and remember what is currently in season and go out of the way to procure them fresh all the time.

We define a reference as entailed when it mentions only information which can be inferred from the table. Each table and reference pair was judged by 3 independent workers, and we used the majority vote as the label for that pair. Overall, only INLINEFORM0 of the references were labeled as entailed by the table. Fleiss' INLINEFORM1 was INLINEFORM2 , which indicates a fair agreement. We found the workers sometimes disagreed on what information can be reasonably entailed by the table.\nFigure FIGREF40 shows the correlations as we vary the percent of entailed examples in the evaluation set of WikiBio. Each point is obtained by fixing the desired proportion of entailed examples, and sampling subsets from the full set which satisfy this proportion. PARENT and RG-F remain stable and show a high correlation across the entire range, whereas BLEU and BLEU-T vary a lot. In the hyperparams category, the latter two have the worst correlation when the evaluation set contains only entailed examples, which may seem surprising. However, on closer examination we found that this subset tends to omit a lot of information from the tables. Systems which produce more information than these references are penalized by BLEU, but not in the human evaluation. PARENT overcomes this issue by measuring recall against the table in addition to the reference.\nWe check how different components in the computation of PARENT contribute to its correlation to human judgments. Specifically, we remove the probability INLINEFORM0 of an n-gram INLINEFORM1 being entailed by the table from Eqs. EQREF19 and EQREF23 . The average correlation for PARENT-W drops to INLINEFORM5 in this case. We also try a variant of PARENT with INLINEFORM6 , which removes the contribution of Table Recall (Eq. EQREF22 ). The average correlation is INLINEFORM7 in this case. With these components, the correlation is INLINEFORM8 , showing that they are crucial to the performance of PARENT.\n BIBREF28 point out that hill-climbing on an automatic metric is meaningless if that metric has a low instance-level correlation to human judgments. In Table TABREF46 we show the average accuracy of the metrics in making the same judgments as humans between pairs of generated texts. Both variants of PARENT are significantly better than the other metrics, however the best accuracy is only INLINEFORM0 for the binary task. This is a challenging task, since there are typically only subtle differences between the texts. Achieving higher instance-level accuracies will require more sophisticated language understanding models for evaluation.\nEach table and reference pair was judged by 3 independent workers, and we used the majority vote as the label for that pair.",

We use 45 tag clusters, the number of POS tags that appear in WSJ corpus. We train the discrete HMM and the Gaussian HMM BIBREF9 as baselines. For the Gaussian HMM, mean vectors of Gaussian emissions are initialized with the empirical mean of all word vectors with an additive noise. We assume diagonal covariance matrix for INLINEFORM0 and initialize it with the empirical variance of the word vectors. Following BIBREF9 , the covariance matrix is fixed during training. The multinomial probabilities are initialized as INLINEFORM1 , where INLINEFORM2 . For our approach, we initialize the syntax model and Gaussian parameters with the pre-trained Gaussian HMM. The weights of layers in the rectified network are initialized from a uniform distribution with mean zero and a standard deviation of INLINEFORM3 , where INLINEFORM4 is the input dimension. We evaluate the performance of POS tagging with both Many-to-One (M-1) accuracy BIBREF23 and V-Measure (VM) BIBREF24 . Given a model we found that the tagging performance is well-correlated with the training data likelihood, thus we use training data likelihood as a unsupervised criterion to select the trained model over 10 random restarts after training 50 epochs. We repeat this process 5 times and report the mean and standard deviation of performance.\nWe compare our approach with basic HMM, Gaussian HMM, and several state-of-the-art systems, including sophisticated HMM variants and clustering techniques with hand-engineered features. The results are presented in Table TABREF32 . Through the introduced latent embeddings and additional neural projection, our approach improves over the Gaussian HMM by 5.4 points in M-1 and 5.6 points in VM. Neural HMM (NHMM) BIBREF10 is a baseline that also learns word representation jointly. Both their basic model and extended Conv version does not outperform the Gaussian HMM. Their best model incorporates another LSTM to model long distance dependency and breaks the Markov assumption, yet our approach still achieves substantial improvement over it without considering more context information.

        "answer": "It is a source-based approach and a consolidated strategy to obtain relevant data for analysis.",
        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31. Besides, when node B retweets node A we have an implicit confirmation that information from A appeared in B's Twitter feed BIBREF12. Quotes are simply a special case of retweets with comments.\nMentions usually include personal conversations as they allow someone to address a specific user or to refer to an individual in the third person; in the first case they are located at the beginning of a tweet and they are known as replies, otherwise they are put in the body of a tweet BIBREF20. The network of mentions is usually seen as a stronger version of interactions between Twitter users, compared to the traditional graph of follower/following relationships BIBREF32.\nTherefore, we follow a source-based approach, a consolidated strategy also adopted by (Shao et al. 2018a)(Shao et al. 2016)(Bovet and Makse 2019)(Grinberg et al. 2019), in order to obtain relevant data for our analysis.",

        "question": "Given these paragraphs about Large language models, what are \"emergent abilities\"?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

It is an isolate language and is classified as threatened by Ethnologue, hence the critical importance of all documentary efforts. Although the morphology of nouns is relatively simple, Mapudungun verb morphology is highly agglutinative and complex. Some analyses provide as many as 36 verb suffix slots BIBREF1. A typical complex verb form occurring in our corpus of spoken Mapudungun consists of five or six morphemes.\nMapudungun has several interesting grammatical properties. It is a polysynthetic language in the sense of BIBREF2; see BIBREF3 for explicit argumentation. As with other polysynthetic languages, Mapudungun has Noun Incorporation; however, it is unique insofar as the Noun appears to the right of the Verb, instead of to the left, as in most polysynthetic languages BIBREF4. One further distinction of Mapudungun is that, whereas other polysynthetic languages are characterized by a lack of infinitives, Mapudungun has infinitival verb forms; that is, while subordinate clauses in Mapudungun closely resemble possessed nominals and may occur with an analytic marker resembling possessor agreement, there is no agreement inflection on the verb itself. One further remarkable property of Mapudungun is its inverse voice system of agreement, whereby the highest agreement is with the argument highest in an animacy hierarchy regardless of thematic role BIBREF5.\nMapudungun (iso 639-3: arn) is an indigenous language of the Americas spoken natively in Chile and Argentina, with an estimated 100 to 200 thousand speakers in Chile and 27 to 60 thousand speakers in Argentina (Z ´u ˜niga, 2006, 41–3) .",

        "question": "What is transistor technology?",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

In Example 2, “UTF8min新生児” (newborn infant) and “UTF8min30歳以上の” (of 30 ‐ year ‐ old or more) are repeated in the output of baseline-NMT, but they appear only once in the output of encoder-decoder-reconstructor.\nIn addition, Figures FIGREF25 and FIGREF25 show the attention layer on baseline-NMT and encoder-decoder-reconstructor in each example. In Figure FIGREF25 , although the attention layer of baseline NMT attends input word “turbulent”, the decoder does not output “UTF8min乱流” (turbulent) but “UTF8min検討” (examined) at the 13th word. Thus, under-translation may be resulted from the hidden layer or the embedding layer instead of the attention layer. In Figure FIGREF25 , it is found that the attention layer of baseline-NMT repeatedly attends input words “newborn infant” and “30 ‐ year ‐ old or more”. Consequently, the decoder repeatedly outputs “UTF8min新生児” (newborn infant) and “UTF8min30歳以上の” (of 30 ‐ year ‐ old or more). On the other hand, the attention layer of encoder-decoder-reconstructor almost correctly attends input words.\nTable TABREF28 shows a comparison of the number of word occurrences for each corpus and model. The columns show (i) the number of words that appear more frequently than the counterparts in the reference, and (ii) the number of words that appear more than once but are not included in the reference. Note that these numbers do not include unknown words, so (iii) shows the number of unknown words. In all the cases, the number of occurrence of redundant words is reduced in encoder-decoder-reconstructor. Thus, we confirmed that encoder-decoder-reconstructor achieves reduction of repeating and missing words while maintaining the quality of translation.\nThus, under-translation may be resulted from the hidden layer or the embedding layer instead of the attention layer.",

It also regularly occurs in Indian defences. The fianchetto is less common in Open Games (1.e4 e5), but the king bishop is sometimes fianchettoed by Black in the Ruy Lopez or by White in an uncommon variation of the Vienna Game.\n\nOne of the major benefits of the fianchetto is that it often allows the fianchettoed bishop to become more active. A fianchettoed position, however, also presents some opportunities for the opponent: if the fianchettoed bishop can be exchanged, the squares the bishop was formerly protecting will become weak (see hole) and can form the basis of an attack (particularly if the fianchetto was performed on the kingside). Exchanging the fianchettoed bishop should not be done lightly, therefore, especially if the enemy bishop on same-coloured squares is still on the board.",

        "evidence": "The goal of data augmentation for contrastive learning is to create realistically rational instances that maintain semantics through different transformation approaches. Unlike instances in vision and language domains, the underlying semantics of time series data is not recognizable to human, making it hard, if not impossible, to include human knowledge to data augmentation for time series data.\nFor example, rotating an image will not change its content or the label. While permuting a time series instance may ruin its signal patterns and generates a meaningless time series instance. In addition, the tremendous heterogeneity of real-life time series datasets further makes selections based on trial-and-errors impractical. Although multiple data augmentation methods have been proposed for time series data, there is less discussion on what is a good augmentation that is meaningful for a given learning task and dataset without prefabricated human priors. From our perspective, ideal data augmentations for contrastive representation should keep high fidelity, high variety, and adaptive to different datasets. The illustration and examples are shown in Figure.\nHigh Fidelity. Augmentations with high fidelity maintain the semantic identity that is invariant to transformations. Considering the inexplicability in practical time series data, it is challenging to visually check the fidelity of augmentations. Thus, we assume that the semantic identity of a time series instance is presented by its label in the downstream task, which might be either available or unavailable during the training period. Here, we start our analysis from the supervised case and will extend it to the unsupervised case later. Based on the information theory, we define the objective that keeps high fidelity as the large mutual information (MI) between augmentation v and the label y, i.e., MI(v; y).\nWe consider augmentation v as a probabilistic function of x and a random variable , that v = g(x; ).\nFrom the definition of mutual information, we have MI(v; y) = H(y) − H(y|v), where H(y) is the (Shannon) entropy of y and H(y|v) is the entropy of y conditioned on augmentation v. Since H(y) is irrelevant to data augmentations, the objective is equivalent to minimizing the conditional entropy H(y|v). Considering the efficient optimization, we follow and to approximate it with cross-entropy between y and ŷ, where ŷ is the prediction with augmentation v as the input and calculated via\nwhere z is the representation and h w (•) is a prediction projector parameterized by w. The prediction projector is optimized by the classification objective. Then, the objective of high fidelity for  supervised or semi-supervised cases is to minimize\nwhere C is the number of labels.\nIn the unsupervised settings where y is unavailable, one-hot encoding y s ∈ R |X| is utilized as the pseudo label to replace y in Eq. (). The motivation is that augmented instances are still distinguishable from other instances with the classifier. We theoretically show that augmentations that preserving pseudo labels have the following properties.\nProperty 1 (Preserving Fidelity). If augmentation v preserves the one-hot encoding pseudo label, the mutual information between v and the downstream task label y (although not visible to training) is equivalent to that between raw input x and y, i.e., MI(v; y) = MI(x; y).\nProperty 2 (Adding New Information). By preserving the one-hot encoding pseudo label, augmentation v contains new information comparing to the raw input x, i.e., H(v) ≥ H(x).\nDetailed proofs are shown in the Appendix A. These properties show that in the unsupervised setting, preserving the one-hot encoding pseudo label guarantees that the generated augmentations will not decrease the fidelity, regardless of the downstream tasks and variances inherent in the augmentations. Concurrently, it may introduce new information for contrastive learning.\nSince the number of labels is equal to the number of instances in dataset X in an unsupervised case, direct optimization of Eq. () is inefficient and unscalable. Thus, we further relax it by approximating y with the batch-wise one-hot encoding y B , which decreases the number of labels C from the dataset size to the batch size.\nHigh Variety. Sufficient variances in augmentations improve the generalization capacity of contrastive learning models. In the information theory, the uncertainty inherent in the random variable's possible outcomes is described by its entropy. Considering that augmented instances are generated based on the raw input x, we maximize the entropy of v conditioned on x, H(v|x), to maintain a high variety of augmentations. From the definition of conditional entropy, we have\nWe dismiss the first part since the unconstrained entropy of v can be dominated by meaningless noise. Considering the continuity of both v and x, we adopt a mutual information neural estimator, InfoNCE to approximately compute the mutual information for its practical effectiveness. Other MI estimators, such as Jensen-Shannon (JSD) estimator, normalized temperature-scaled cross-entropy (NT-Xent), and leaveone-out can also conveniently be the plug-and-play component in our framework. Then, the objective to encourage high variety is to maximize the InfoNCE between v and x:\nx ∈X exp(sim(z x , z v ))\nwhere v is an augmented instance of input instance x . z x , z v , and z v are representations of instance x, v, and v respectively. sim(z 1 , z 2 ) = z T 1 z 2 is the inner product of vectors z 1 and z 2 .\nCriteria. Combining the information aware definition of both high fidelity and variety, we propose the criteria for selecting good augmentations without prior knowledge,\nwhere β is a hyper-parameter to achieve the trade-off between fidelity and variety. Note that in the unsupervised settings, y is replaced by one-hot encoding pseudo label... Similar to the information bottleneck, InfoMin assumes that augmented views are functions of the input, which heavily constrains the variance of data augmentations. Besides, high fidelity property is dismissed in the unsupervised setting. It works for image datasets due to the availability of human knowledge. However, it may fail to generate reasonable augmentations for time series data.\nSince the number of labels is equal to the number of instances in dataset X in an unsupervised case, direct optimization of Eq. (2) is inefficient and unscalable. Thus, we further relax it by approximating y with the batch-wise one-hot encoding yB, which decreases the number of labels C from the dataset size to the batch size.",

This map was later included in a literary and historical atlas of America by Bartholomew in 1884, with light blue areas marking regions that were not originally present on the map.\n\nToscanelli served as an inspiration for Columbus, who received a letter from him on June 25, 1474. The letter was sent to canon Fernam Martins in Lisbon, who consulted Toscanelli on behalf of King Alfonso V about the possibility of reaching India through a western route.\n\nThe map clearly shows that Columbus was both inspired and misguided by Toscanelli's plan, which underestimated the Earth's circumference. This miscalculation led Columbus to believe that he had reached Japan instead of a completely new and unfamiliar continent lying between Europe and Asia.\n\nToscanelli's proposed plan involved sailing west along the equator to reach India and the wealthy countries of East Asia. The map that Toscanelli enclosed, which is now lost, included the western fringes of Europe and Africa, as well as the eastern fringes of Asia, with the Atlantic Ocean in between. However, Toscanelli mistakenly believed that the distance was only one-third of the Earth's circumference, far less than the actual distance.\n\nIn a letter, Toscanelli writes, among other things:\n\nI have already spoken once before of a route across the sea to the land of spices, much shorter than that of the Portuguese across Guinea. That is why His Highness the King is now asking me for information on this subject, or rather for an explanation so clear that even people without any scientific background can understand that this path must exist.

        "evidence": "Automatic summarization has enjoyed wide popularity in natural language processing due to its potential for various information access applications. Examples include tools which aid users navigate and digest web content (e.g., news, social media, product reviews), question answering, and personalized recommendation engines. Single document summarization — the task of producing a shorter version of a document while preserving its information content — is perhaps the most basic of summarization tasks that have been identified over the years (see BIBREF0 , BIBREF0 for a comprehensive overview).\nModern approaches to single document summarization are data-driven, taking advantage of the success of neural network architectures and their ability to learn continuous features without recourse to preprocessing tools or linguistic annotations. Abstractive summarization involves various text rewriting operations (e.g., substitution, deletion, reordering) and has been recently framed as a sequence-to-sequence problem BIBREF1 . Central in most approaches BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 is an encoder-decoder architecture modeled by recurrent neural networks. The encoder reads the source sequence into a list of continuous-space representations from which the decoder generates the target sequence. An attention mechanism BIBREF8 is often used to locate the region of focus during decoding.\nExtractive systems create a summary by identifying (and subsequently concatenating) the most important sentences in a document. A few recent approaches BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 conceptualize extractive summarization as a sequence labeling task in which each label specifies whether each document sentence should be included in the summary. Existing models rely on recurrent neural networks to derive a meaning representation of the document which is then used to label each sentence, taking the previously labeled sentences into account. These models are typically trained using cross-entropy loss in order to maximize the likelihood of the ground-truth labels and do not necessarily learn to rank sentences based on their importance due to the absence of a ranking-based objective. Another discrepancy comes from the mismatch between the learning objective and the evaluation criterion, namely ROUGE BIBREF13 , which takes the entire summary into account.\nIn this paper we argue that cross-entropy training is not optimal for extractive summarization. Models trained this way are prone to generating verbose summaries with unnecessarily long sentences and redundant information. We propose to overcome these difficulties by globally optimizing the ROUGE evaluation metric and learning to rank sentences for summary generation through a reinforcement learning objective. Similar to previous work BIBREF9 , BIBREF11 , BIBREF10 , our neural summarization model consists of a hierarchical document encoder and a hierarchical sentence extractor. During training, it combines the maximum-likelihood cross-entropy loss with rewards from policy gradient reinforcement learning to directly optimize the evaluation metric relevant for the summarization task. We show that this global optimization framework renders extractive models better at discriminating among sentences for the final summary; a sentence is ranked high for selection if it often occurs in high scoring summaries.\nWe report results on the CNN and DailyMail news highlights datasets BIBREF14 which have been recently used as testbeds for the evaluation of neural summarization systems. Experimental results show that when evaluated automatically (in terms of ROUGE), our model outperforms state-of-the-art extractive and abstractive systems. We also conduct two human evaluations in order to assess (a) which type of summary participants prefer (we compare extractive and abstractive systems) and (b) how much key information from the document is preserved in the summary (we ask participants to answer questions pertaining to the content in the document by reading system summaries). Both evaluations overwhelmingly show that human subjects find our summaries more informative and complete.\nOur contributions in this work are three-fold: a novel application of reinforcement learning to sentence ranking for extractive summarization; corroborated by analysis and empirical results showing that cross-entropy training is not well-suited to the summarization task; and large scale user studies following two evaluation paradigms which demonstrate that state-of-the-art abstractive systems lag behind extractive ones when the latter are globally trained.\ncorroborated by analysis and empirical results showing that cross-entropy training is not well-suited to the summarization task;",

        "evidence": "BIBREF13 proposed a MP framework under which many of the recently introduced GNNs can be reformulated. MP consists in an aggregation phase followed by a combination phase BIBREF14. More precisely, let $G(V,E)$ be a graph, and let us consider $v \\in V$. At time $t+1$, a message vector $\\mathbf {m}_v^{t+1}$ is computed from the representations of the neighbors $\\mathcal {N}(v)$ of $v$:\n\nThe new representation $\\mathbf {h}^{t+1}_v$ of $v$ is then computed by combining its current feature vector $\\mathbf {h}^{t}_v$ with the message vector $\\mathbf {m}_v^{t+1}$:\n\nMessages are passed for $T$ time steps. Each step is implemented by a different layer of the MP network. Hence, iterations correspond to network depth. The final feature vector $\\mathbf {h}_v^T$ of $v$ is based on messages propagated from all the nodes in the subtree of height $T$ rooted at $v$. It captures both the topology of the neighborhood of $v$ and the distribution of the vertex representations in it.\nIf a graph-level feature vector is needed, e.g., for classification or regression, a READOUT pooling function, that must be invariant to permutations, is applied:\n\nNext, we present the MP network we developed for document understanding.\nWe represent a document as a statistical word co-occurrence network BIBREF18, BIBREF19 with a sliding window of size 2 overspanning sentences. Let us denote that graph $G(V,E)$. Each unique word in the preprocessed document is represented by a node in $G$, and an edge is added between two nodes if they are found together in at least one instantiation of the window. $G$ is directed and weighted: edge directions and weights respectively capture text flow and co-occurrence counts.\n$G$ is a compact representation of its document. In $G$, immediate neighbors are consecutive words in the same sentence. That is, paths of length 2 correspond to bigrams. Paths of length more than 2 can correspond either to traditional $n$-grams or to relaxed $n$-grams, that is, words that never appear in the same sentence but co-occur with the same word(s). Such nodes are linked through common neighbors.\nMaster node. Inspired by BIBREF3, our $G$ also includes a special document node, linked to all other nodes via unit weight bi-directional edges. In what follows, let us denote by $n$ the number of nodes in $G$, including the master node.\nWe formulate our AGGREGATE function as:\n\nwhere $\\mathbf {H}^t \\in \\mathbb {R}^{n \\times d}$ contains node features ($d$ is a hyperparameter), and $\\mathbf {A} \\in \\mathbb {R}^{n \\times n}$ is the adjacency matrix of $G$. Since $G$ is directed, $\\mathbf {A}$ is asymmetric. Also, $\\mathbf {A}$ has zero diagonal as we choose not to consider the feature of the node itself, only that of its incoming neighbors, when updating its representation. Since $G$ is weighted, the $i^{th}$ row of $A$ contains the weights of the edges incoming on node $v_i$. $\\mathbf {D} \\in \\mathbb {R}^{n \\times n}$ is the diagonal in-degree matrix of $G$. MLP denotes a multi-layer perceptron, and $\\mathbf {M}^{t+1} \\in \\mathbb {R}^{n \\times d}$ is the message matrix.\nThe use of a MLP was motivated by the observation that for graph classification, MP neural nets with 1-layer perceptrons are inferior to their MLP counterparts BIBREF14. Indeed, 1-layer perceptrons are not universal approximators of multiset functions. Note that like in BIBREF14, we use a different MLP at each layer.\nRenormalization. The rows of $\\mathbf {D}^{-1}\\mathbf {A}$ sum to 1. This is equivalent to the renormalization trick of BIBREF9, but using only the in-degrees. That is, instead of computing a weighted sum of the incoming neighbors' feature vectors, we compute a weighted average of them. The coefficients are proportional to the strength of co-occurrence between words. One should note that by averaging, we lose the ability to distinguish between different neighborhood structures in some special cases, that is, we lose injectivity. Such cases include neighborhoods in which all nodes have the same representations, and neighborhoods of different sizes containing various representations in equal proportions BIBREF14. As suggested by the results of an ablation experiment, averaging is better than summing in our application (see subsection SECREF30). Note that instead of simply summing/averaging, we also tried using GAT-like attention BIBREF11 in early experiments, without obtaining better results.\nAs far as our COMBINE function, we use the Gated Recurrent Unit BIBREF20, BIBREF21:\n\nOmitting biases for readability, we have:\n\nwhere the $\\mathbf {W}$ and $\\mathbf {U}$ matrices are trainable weight matrices not shared across time steps, $\\sigma (\\mathbf {x}) = 1/(1+\\exp (-\\mathbf {x}))$ is the sigmoid function, and $\\mathbf {R}$ and $\\mathbf {Z}$ are the parameters of the reset and update gates. The reset gate controls the amount of information from the previous time step (in $\\mathbf {H}^t$) that should propagate to the candidate representations, $\\tilde{\\mathbf {H}}^{t+1}$. The new representations $\\mathbf {H}^{t+1}$ are finally obtained by linearly interpolating between the previous and the candidate ones, using the coefficients returned by the update gate.\nInterpretation. Updating node representations through a GRU should in principle allow nodes to encode a combination of local and global signals (low and high values of $t$, resp.), by allowing them to remember about past iterations. In addition, we also explicitly consider node representations at all iterations when reading out (see Eq. DISPLAY_FORM18).\n\nAfter passing messages and performing updates for $T$ iterations, we obtain a matrix $\\mathbf {H}^T \\in \\mathbb {R}^{n \\times d}$ containing the final vertex representations. Let $\\hat{G}$ be graph $G$ without the special document node, and matrix $\\mathbf {\\hat{H}}^T \\in \\mathbb {R}^{(n-1) \\times d}$ be the corresponding representation matrix (i.e., $\\mathbf {H}^T$ without the row of the document node).\nWe use as our READOUT function the concatenation of self-attention applied to $\\mathbf {\\hat{H}}^T$ with the final document node representation. More precisely, we apply a global self-attention mechanism BIBREF22 to the rows of $\\mathbf {\\hat{H}}^T$. As shown in Eq. DISPLAY_FORM17, $\\mathbf {\\hat{H}}^T$ is first passed to a dense layer parameterized by matrix $\\mathbf {W}_A^T \\in \\mathbb {R}^{d \\times d}$. An alignment vector $\\mathbf {a}$ is then derived by comparing, via dot products, the rows of the output of the dense layer $\\mathbf {Y}^T \\in \\mathbb {R}^{(n-1) \\times d}$ with a trainable vector $\\mathbf {v}^T \\in \\mathbb {R}^d$ (initialized randomly) and normalizing with a softmax. The normalized alignment coefficients are finally used to compute the attentional vector $\\mathbf {u}^T \\in \\mathbb {R}^d$ as a weighted sum of the final representations $\\mathbf {\\hat{H}}^T$.\n\n\nNote that we tried with multiple context vectors, i.e., with a matrix $\\mathbf {V}^T$ instead of a vector $\\mathbf {v}^T$, like in BIBREF22, but results were not convincing, even when adding a regularization term to the loss to favor diversity among the rows of $\\mathbf {V}^T$.\nMaster node skip connection. $\\mathbf {h}_G^T \\in \\mathbb {R}^{2d}$ is obtained by concatenating $\\mathbf {u}^T$ and the final master node representation. That is, the master node vector bypasses the attention mechanism. This is equivalent to a skip or shortcut connection BIBREF23. The reason behind this choice is that we expect the special document node to learn a high-level summary about the document, such as its size, vocabulary, etc. (more details are given in subsection SECREF30). Therefore, by making the master node bypass the attention layer, we directly inject global information about the document into its final representation.\nMulti-readout. BIBREF14, inspired by Jumping Knowledge Networks BIBREF12, recommend to not only use the final representations when performing readout, but also that of the earlier steps. Indeed, as one iterates, node features capture more and more global information. However, retaining more local, intermediary information might be useful too. Thus, instead of applying the readout function only to $t=T$, we apply it to all time steps and concatenate the results, finally obtaining $\\mathbf {h}_G \\in \\mathbb {R}^{T \\times 2d}$ :\n\nIn effect, with this modification, we take into account features based on information aggregated from subtrees of different heights (from 1 to $T$), corresponding to local and global features.\nThrough the successive MP iterations, it could be argued that MPAD implicitly captures some soft notion of the hierarchical structure of documents (words $\\rightarrow $ bigrams $\\rightarrow $ compositions of bigrams, etc.). However, it might be beneficial to explicitly capture document hierarchy. Hierarchical architectures have brought significant improvements to many NLP tasks, such as language modeling and generation BIBREF24, BIBREF25, sentiment and topic classification BIBREF26, BIBREF27, and spoken language understanding BIBREF28, BIBREF29. Inspired by this line of research, we propose several hierarchical variants of MPAD, detailed in what follows. In all of them, we represent each sentence in the document as a word co-occurrence network, and obtain an embedding for it by applying MPAD as previously described.\nMPAD-sentence-att. Here, the sentence embeddings are simply combined through self-attention.\nMPAD-clique. In this variant, we build a complete graph where each node represents a sentence. We then feed that graph to MPAD, where the feature vectors of the nodes are initialized with the sentence embeddings previously obtained.\nMPAD-path. This variant is similar to the clique one, except that instead of a complete graph, we build a path according to the natural flow of the text. That is, two nodes are linked by a directed edge if the two sentences they represent follow each other in the document.\nNote that we tried with multiple context vectors, i.e., with matrix VT instead of a vector vT, like in (Lin et al. 2017), but results were not convincing, even when adding a reg larization term to the loss to favor diversity among the ro of VT.",

He was able to perform word sense disambiguation by identifying the senses of words in a sentence with the largest number of overlaps between their definitions. An overlap is the longest sequence of one or more consecutive words that occur in both definitions. BanerjeeP03 extended this idea to WordNet, but observed that WordNet glosses are often very short, and did not contain enough information to distinguish between multiple concepts. Therefore, they created a super–gloss for each concept by adding the glosses of related concepts to the gloss of the concept itself (and then finding overlaps).\nPatwardhanP06 adapted this measure to second–order co–occurrence vectors. In this approach, a vector is created for each word in a concept's definition that shows which words co–occur with it in a corpus. These word vectors are averaged to create a single co-occurrence vector for the concept. The similarity between the concepts is calculated by taking the cosine between the concepts second–order vectors. LiuMPMP12 modified and extended this measure to be used to quantify the relatedness between biomedical and clinical terms in the UMLS.

        "question": "From the text provided, extract the list of styles found on Budapest architecture. Separate them with a semi-colon.",
        "evidence": "Budapest has architecturally noteworthy buildings in a wide range of styles and from distinct time periods, from the ancient times as Roman City of Aquincum in Óbuda (District III), which dates to around 89 AD, to the most modern Palace of Arts, the contemporary arts museum and concert hall.\n\nMost buildings in Budapest are relatively low: in the early 2010s there were around 100 buildings higher than 45 metres (148 ft). The number of high-rise buildings is kept low by building legislation, which is aimed at preserving the historic cityscape and to meet the requirements of the World Heritage Site. Strong rules apply to the planning, authorisation and construction of high-rise buildings and consequently much of the inner city does not have any. Some planners would like see an easing of the rules for the construction of skyscrapers, and the possibility of building skyscrapers outside the city's historic core has been raised.\n\nIn the chronological order of architectural styles Budapest is represented on the entire timeline, starting with the Roman City of Aquincum representing ancient architecture.\n\nThe next determinative style is the Gothic architecture in Budapest. The few remaining Gothic buildings can be found in the Castle District. Buildings of note are no. 18, 20 and 22 on Országház Street, which date back to the 14th century and No. 31 Úri Street, which has a Gothic façade that dates back to the 15th century. Other buildings with Gothic features are the Inner City Parish Church, built in the 12th century, and the Mary Magdalene Church, completed in the 15th century. The most characteristic Gothic-style buildings are actually Neo-Gothic, like the most well-known Budapest landmarks, the Hungarian Parliament Building and the Matthias Church, where much of the original material was used (originally built in Romanesque style in 1015).\n\nThe next chapter in the history of human architecture is Renaissance architecture. One of the earliest places to be influenced by the Renaissance style of architecture was Hungary, and Budapest in particular. The style appeared following the marriage of King Matthias Corvinus and Beatrice of Naples in 1476. Many Italian artists, craftsmen and masons came to Buda with the new queen. Today, many of the original renaissance buildings disappeared during the varied history of Buda, but Budapest is still rich in renaissance and neo-renaissance buildings, like the famous Hungarian State Opera House, St. Stephen's Basilica and the Hungarian Academy of Sciences.\n\nDuring the Turkish occupation (1541–1686), Islamic culture flourished in Budapest; multiple mosques and baths were built in the city. These were great examples of Ottoman architecture, which was influenced by Muslims from around the world including Turkish, Iranian, Arabian and to a larger extent, Byzantine architecture as well as Islamic traditions. After the Holy League conquered Budapest, they replaced most of the mosques with churches and minarets were turned into bell towers and cathedral spires. At one point the distinct sloping central square in Budapest became a bustling Oriental bazaar, which was filled with \"the chatter of camel caravans on their way to Yemen and India\". Budapest is in fact one of the few places in the world with functioning original Turkish bathhouses dating back to the 16th century, like Rudas Baths or Király Baths. Budapest is home to the northernmost place where the tomb of influential Islamic Turkish Sufi Dervish, Gül Baba is found. Various cultures converged in Hungary seemed to coalesce well with each other, as if all these different cultures and architecture styles are digested into Hungary's own way of cultural blend. A precedent to show the city's self-conscious is the top section of the city's main square, named as Szechenyi. When Turks came to the city, they built mosques here which was aggressively replaced with Gothic church of St. Bertalan. The rationale of reusing the base of the former Islamic building mosque and reconstruction into Gothic Church but Islamic style architecture over it is typically Islamic are still visible. An official term for the rationale is spolia. The mosque was called the djami of Pasha Gazi Kassim, and djami means mosque in Arabic. After Turks and Muslims were expelled and massacred from Budapest, the site was reoccupied by Christians and reformed into a church, the Inner City Parish Church (Budapest). The minaret and Turkish entranceway were removed. The shape of the architecture is its only hint of exotic past—\"two surviving prayer niches facing Mecca and an ecumenical symbol atop its cupola: a cross rising above the Turkish crescent moon\".\n\n\nThe most famous Budapest bridge, the Chain Bridge, the icon of the city's 19th century development, built in 1849\nAfter 1686, the Baroque architecture designated the dominant style of art in catholic countries from the 17th century to the 18th century. There are many Baroque-style buildings in Budapest and one of the finest examples of preserved Baroque-style architecture is the Church of St. Anna in Batthyhány square. An interesting part of Budapest is the less touristy Óbuda, the main square of which also has some beautiful preserved historic buildings with Baroque façades. The Castle District is another place to visit where the best-known landmark Buda Royal Palace and many other buildings were built in the Baroque style.\n\nThe Classical architecture and Neoclassical architecture are the next in the timeline. Budapest had not one but two architects that were masters of the Classicist style. Mihály Pollack (1773–1855) and József Hild (1789–1867), built many beautiful Classicist-style buildings in the city. Some of the best examples are the Hungarian National Museum, the Lutheran Church of Budavár (both designed by Pollack) and the seat of the Hungarian president, the Sándor Palace. The most iconic and widely known Classicist-style attraction in Budapest is the Széchenyi Chain Bridge. Budapest's two most beautiful Romantic architecture buildings are the Great Synagogue in Dohány Street and the Vigadó Concert Hall on the Danube Promenade, both designed by architect Frigyes Feszl (1821–1884). Another noteworthy structure is the Budapest Western Railway Station, which was designed by August de Serres and built by the Eiffel Company of Paris in 1877.\n\n\nThe Hungarian Parliament, completed in 1904\nArt Nouveau came into fashion in Budapest by the exhibitions which were held in and around 1896 and organised in connection with the Hungarian Millennium celebrations. Art Nouveau in Hungary (Szecesszió in Hungarian) is a blend of several architectural styles, with a focus on Hungary's specialities. One of the leading Art Nouveau architects, Ödön Lechner (1845–1914), was inspired by Indian and Syrian architecture as well as traditional Hungarian decorative designs. One of his most beautiful buildings in Budapest is the Museum of Applied Arts. Another examples for Art Nouveau in Budapest is the Gresham Palace in front of the Chain Bridge, the Hotel Gellért, the Franz Liszt Academy of Music or Budapest Zoo and Botanical Garden.\n\nIt is one of the world's outstanding urban landscapes and illustrates the great periods in the history of the Hungarian capital.\n\nUNESCO\nThe second half of the 20th century also saw, under the communist regime, the construction of blocks of flats (panelház), as in other Eastern European countries. In the 21st century, Budapest faces new challenges in its architecture. The pressure towards the high-rise buildings is unequivocal among today's world cities, but preserving Budapest's unique cityscape and its very diverse architecture, along with green areas, is force Budapest to balance between them. The Contemporary architecture has wide margin in the city. Public spaces attract heavy investment by business and government also, so that the city has gained entirely new (or renovated and redesigned) squares, parks and monuments, for example the city central Kossuth Lajos square, Deák Ferenc square and Liberty Square. Numerous landmarks are created in the last decade in Budapest, like the National Theatre, Palace of Arts, Rákóczi Bridge, Megyeri Bridge, Budapest Airport Sky Court among others, and millions of square meters of new office buildings and apartments. But there are still large opportunities in real estate development in the city.",

        "answer": "Yes.",
        "evidence": "Word embeddings are low-dimensional, dense vector representations that capture semantic properties of words. Recently, they have gained tremendous popularity in Natural Language Processing (NLP) and have been used in tasks as diverse as text similarity BIBREF0 , part-of-speech tagging BIBREF1 , sentiment analysis BIBREF2 , and machine translation BIBREF3 . Although word embeddings are widely used across NLP, their stability has not yet been fully evaluated and understood. In this paper, we explore the factors that play a role in the stability of word embeddings, including properties of the data, properties of the algorithm, and properties of the words. We find that word embeddings exhibit substantial instabilities, which can have implications for downstream tasks.\nUsing the overlap between nearest neighbors in an embedding space as a measure of stability (see sec:definingStability below for more information), we observe that many common embedding spaces have large amounts of instability. For example, Figure FIGREF1 shows the instability of the embeddings obtained by training word2vec on the Penn Treebank (PTB) BIBREF4 . As expected, lower frequency words have lower stability and higher frequency words have higher stability. What is surprising however about this graph is the medium-frequency words, which show huge variance in stability. This cannot be explained by frequency, so there must be other factors contributing to their instability.\nIn the following experiments, we explore which factors affect stability, as well as how this stability affects downstream tasks that word embeddings are commonly used for. To our knowledge, this is the first study comprehensively examining the factors behind instability.\nTo our knowledge, this is the first study comprehensively examining the factors behind instability.",

        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nTo the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective.",

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nwe show which discourse phenomena are hard to capture using monolingual data only.",

If the leak only happens when it is raining, then shut off the main water supply and see if the leak still happens.  If yes, then it is likely from rain.  If it has been sunny and dry for a week and you are still getting the leak, shut the water off and see if the leak stops.  If it does, then that is likely from an internal leak.  If it is in fact an internal leak, then call a reputable local plumber to have them test your pipes for pressure loss.  If it is an external leak, then wait for sunny weather.  After about a week of dry sunny weather, get a garden hose and pick a feature of your roof or external walls and spray that feature (vent pipe, window, roof juncture, etc) with a direct stream of high volume and low velocity water from the garden hose.  Wait for a few hours, and see if the leak appears.  After four hours, if no leak has appeared, then move on to the next feature.

He was a member of the Chamber of Deputies from 1994 to 2013, and has served as a member of the Senate of the Republic since 2022, and previously from March to November 2013, and as a Member of the European Parliament (MEP) since 2019, and previously from 1999 to 2001.\n\nBerlusconi is the controlling shareholder of Mediaset and owned the Italian football club A.C. Milan from 1986 to 2017. He is nicknamed Il Cavaliere (The Knight) for his Order of Merit for Labour. \nThe Order of Merit for Labour (Italian: Ordine al Merito del Lavoro) is an Italian order of chivalry that was founded in 1923 by King Vittorio Emanuele III. It is awarded to those \"who have been singularly meritorious\" in agriculture, industry and commerce, crafts, lending and insurance. It is a continuation of the earlier Ordine al Merito Agrario, Industriale e Commerciale founded in 1901. Members of the order may use the title Cavaliere del lavoro.\n\nHe voluntarily resigned from this order in March 2014. In 2018, Forbes ranked him as the 190th richest man in the world with a net worth of US$8 billion. In 2009, Forbes ranked him 12th in the list of the World's Most Powerful People due to his domination of Italian politics throughout more than twenty years at the head of the centre-right coalition.\n\nBerlusconi was Prime Minister for nine years in total, making him the longest serving post-war Prime Minister of Italy, and the third longest-serving since Italian unification, after Benito Mussolini and Giovanni Giolitti. He was the leader of the centre-right party Forza Italia from 1994 to 2009, and its successor party The People of Freedom from 2009 to 2013. Since November 2013, he has led a revived Forza Italia. Berlusconi was the senior G8 leader from 2009 until 2011, and he currently holds the record for hosting G8 summits (having hosted three summits in Italy).

TED (and TEDx) Talks - TED Talks are popular videos that present a great idea in 18 minutes or less. While TED talks are intended for a global audience, TEDx talks are intended for smaller audiences and are usually presented at a local level. TED and TEDx talk videos are readily available for consumption, for free from the website www.ted.com, via a mobiule app, as well as on Spotify, YouTube and many other content platforms.\n\n2. Podcasts - Podcasts are a series of on-demand episodes, delivered orally, focused on a specific theme. Podcasts can be accessed from many types of devices and are readily available from many popular platforms, including Spotify, Apple Podcasts and iHeartRadio. Podcasts are focused on any number of topics, and can easily be listened to while on the go. \n\n3. Newsletters - Newsletters are printed or electronic reports that are made available by many organizations to a subscribed audience. They are often written in short, digestible formats to provide the highlights of a variety of topics, and typically contain links to learn more, if desired. They usually take only a few minutes to read and are readily available from news sources like the Wall Street Journal, CNN, Fox News, as well as many websites and LinkedIn groups. \n\nIn addition to these ideas, simply dedicating a small amount of time each day to learning and improving yourself can go a long way.

However, the discovery of oats and barley on the plains at about 15,000 BCE suggests that agriculture had already developed at this early date.\n\nSeveral minute granite tools (about 4 centimetres in length), earthenware, remnants of charred timber, and clay burial pots date to the Mesolithic.

By considering only average acc, we can underestimate the forgetting by reaching the high performance on the current task. Even if our method shows slightly lower value on average acc, we can observe that our algorithm shows the better perfomance on the forgetting metric.",
        "evidence": "The following tables show our main experimental result, which is averaged over 5 runs. We denote the number of example per class per task at the top of each column. Overall, NCCL variants outperforms baseline methods especially in the forgetting metric. Our goal is to demonstrate the usefulness of the adaptive learning rate scheme to reduce the catastrophic forgetting, and verify the proposed theoretical convergence analysis. We remark that our adaptive learning rates successfully suppress forgetting by a large margin compared to baselines. Note that NCCL also outperform A-GEM, which does not maximize transfer ∇f It (x t ), ∇g Jt (x t ) > 0. Now, we can empirically demonstrate our theoretical guaranteed method by minimizing Γ t is valid.\nWe clipped β Ht to increase the performance. As we discussed earlier, we can prevent forgetting when ∇f It (x t ), ∇g Jt (x t ) > 0. However, we observe that ∇f It (x t ) 2 suddenly increases because of the interference at the previous step t − 1. The very large learning rate β Ht by the increased ∇f It (x t ) can force the model to fall into an arbitrary point that is likely to increase the loss of f . Clipping the learning rate reduces this problem and still has the effect of reducing the catastrophic forgetting term Γ t . By the property of quadratic polynomial, the catastrophic forgetting term is negative because the clipped value is smaller than the original learning rate.\nWe show that NCCL is a potentially powerful alternative for continual learning. Even with tiny replay memory, NCCL still performs better than some baselines. We note that NCCL shows the best performance on the forgetting metric. It implies that NCCL prevent catastrophic forgetting more efficiently than others by minimizing the catastrophic forgetting term in the proposed optimization problem. However, the accuracy is slightly lower than other baselines, which include experience replays. The purpose of our adaptive learning rate scheme is to prevent catastrophic forgetting, so the performance of current task is slightly lower than ER-Ring, stable-SGD, and ORTHOG-subspace. This result shows that the plasticity to learn a new task is restricted by NCCL variants with tiny memory. In particular, we would expect that NCCL would benefit from the additional enhancements in ORTHOG-SUBSPACE and stable SGD by introducing their techniques. In appendix, we add more results with larger sizes of memory, which shows that NCCL outperforms on the average accuracy. We conclude that the transfer effect by the small size of memory for NCCL is less effective.\nWe show that NCCL is a potentially powerful alternative for continual learning.

Common seasonings for brisket are salt, pepper and garlic.  It is recommend to season the brisket for at least 30 minutes before cooking but for best results allow the seasoned brisket to rest overnight in your refrigerator.  Once the brisket is properly seasoned, place the brisket on your pellet grill.  It is common in Texas to place the brisket fat side up.  In other areas of the country, it is more common to place the brisket fat side down.  Allow your brisket to smoke until it reaches an internal temperature of 175 degrees.  Depending on the size of the brisket this could take in excess of 12 hours.  Once the brisket reaches an internal temperature of 175 degrees, wrap the brisket with butcher paper to build better bark.  Alternatively you can wrap the brisket in foil which will finish the cooking faster but build less bark.  Place the wrapped brisket back in your pellet smoker and increase the temperature to 275 degrees Fahrenheit.  Once the brisket reaches a temperature of 205 degrees Fahrenheit remove the brisket from our pellet smoker and allow it to rest in a cooler or oven until the brisket reaches an internal temperature of 140 degrees.

These murals not only add beauty and character to the city, but also serve as a form of public art that is accessible to everyone.\n\nThe murals in Jersey City come in all shapes and sizes, with a variety of themes and styles. Some feature colorful abstract designs, while others depict realistic images of people, animals, and landscapes. Many of the murals also incorporate social and political messages, addressing issues such as social justice, inequality, and the environment.\n\nOne of the most famous murals in Jersey City is the \"Sixth Borough\" mural, which depicts the city as a mythical sixth borough of New York City. This mural, which covers an entire building, has become an iconic symbol of Jersey City's identity and sense of community.\n\nThe murals in Jersey City are created by a diverse group of artists, both local and international. Some are commissioned by the city or private businesses, while others are created by artists who are drawn to the city's thriving street art scene. Many of the murals are created as part of organized events, such as the annual Jersey City Mural Festival, which brings together artists from around the world to create new works throughout the city.\n\nThe murals in Jersey City are not only beautiful and inspiring, but also serve as a reflection of the city's culture, history, and values.

One of the first kingdoms to rise to power in the territory was the kingdom of D'mt in the 10th century BC, which established its capital at Yeha. In the first century AD the Aksumite Kingdom rose to power in the Tigray Region with its capital at Aksum and grew into a major power on the Red Sea, subjugating Yemen and Meroe. In the early fourth century, during the reign of Ezana, Christianity was declared the state religion. Ezana's reign is also when the Aksumites first identified themselves as \"Ethiopians\", and not long after, Philostorgius became the first foreign author to call the Aksumites Ethiopians. The Aksumite empire fell into decline with the rise of Islam in the Arabian peninsula, which slowly shifted trade away from the Christian Aksum. It eventually became isolated, its economy slumped and Aksum's commercial domination of the region ended. The Aksumites gave way to the Zagwe dynasty, who established a new capital at Lalibela before giving way to the Solomonic dynasty in the 13th century.

In cool climates (such as Chablis and the Carneros AVA of California), Chardonnay wine tends to be medium to light body with noticeable acidity and flavors of green plum, apple, and pear. In warmer locations (such as the Adelaide Hills and Mornington Peninsula in Australia and Gisborne and Marlborough region of New Zealand), the flavors become more citrus, peach, and melon, while in very warm locations (such as the Central Coast AVA of California), more fig and tropical fruit notes such as banana and mango come out.

It has a pale, clear, yellowish broth made with plenty of salt and any combination of chicken, vegetables, fish, and seaweed. Occasionally pork bones are also used, but they are not boiled as long as they are for tonkotsu ramen, so the soup remains light and clear. Chāshū is sometimes swapped for lean chicken meatballs, and pickled plums and kamaboko (a slice of processed fish roll sometimes served as a frilly white circle with a pink or red spiral called narutomaki) are popular toppings as well. Noodle texture and thickness varies among shio ramen, but they are usually straight rather than curly. Hakodate ramen is a well-known version of shio ramen in Japan.\nShōyu (醤油, 'soy sauce') ramen has a clear brown broth, based on a chicken and vegetable (or sometimes fish or beef) stock with plenty of soy sauce added resulting in a soup that is tangy, salty, and savory yet still fairly light on the palate. Shōyu ramen usually has curly noodles rather than straight ones, although this is not always the case. It is often adorned with marinated bamboo shoots or menma, scallions, ninjin ('carrot'), kamaboko ('fish cakes'), nori ('seaweed'), boiled eggs, bean sprouts or black pepper; occasionally the soup will also contain chili oil or Chinese spices, and some shops serve sliced beef instead of the usual chāshū.\nMiso (味噌) ramen reached national prominence around 1965. This uniquely Japanese ramen, which was developed in Sapporo Hokkaido, features a broth that combines copious miso and is blended with oily chicken or fish broth – and sometimes with tonkotsu or lard – to create a thick, nutty, slightly sweet and very hearty soup. Miso ramen broth tends to have a robust, tangy flavor, so it stands up to a variety of flavorful toppings: spicy bean paste or tōbanjan (豆瓣醤), butter and corn, leeks, onions, bean sprouts, ground pork, cabbage, sesame seeds, white pepper, chilli and chopped garlic are common. The noodles are typically thick, curly, and slightly chewy.\nKarē (カレー, 'curry') ramen is a relative newcomer, cooked with curry soup. In Japan, several cities claim to be its place of origin. The city of Muroran claims it originated there in 1965 (see also Muroran curry ramen), while the city of Sanjō claims to have had karē ramen for over 80 years, and the city of Katori also claims to have been the site of its origin.

        "evidence": "To paraphrase the great bard BIBREF21, there is something rotten in the state of the art. We propose Human-And-Model-in-the-Loop Entailment Training (HAMLET), a training procedure to automatically mitigate problems with current dataset collection procedures (see Figure FIGREF1).\nIn our setup, our starting point is a base model, trained on NLI data. Rather than employing automated adversarial methods, here the model's “adversary” is a human annotator. Given a context (also often called a “premise” in NLI), and a desired target label, we ask the human writer to provide a hypothesis that fools the model into misclassifying the label. One can think of the writer as a “white hat” hacker, trying to identify vulnerabilities in the system. For each human-generated example that is misclassified, we also ask the writer to provide a reason why they believe it was misclassified.\nFor examples that the model misclassified, it is necessary to verify that they are actually correct —i.e., that the given context-hypothesis pairs genuinely have their specified target label. The best way to do this is to have them checked by another human. Hence, we provide the example to human verifiers. If two human verifiers agree with the writer, the example is considered a good example. If they disagree, we ask a third human verifier to break the tie. If there is still disagreement between the writer and the verifiers, the example is discarded. Occasionally, verifiers will overrule the original label of the writer.\nOnce data collection for the current round is finished, we construct a new training set from the collected data, with accompanying development and test sets. While the training set includes correctly classified examples, the development and tests sets are built solely from them. The test set was further restricted so as to: 1) include pairs from “exclusive” annotators that are never included in the training data; and 2) be balanced by label classes (and genres, where applicable). We subsequently train a new model on this and other existing data, and repeat the procedure three times.\nWe propose Human-And-Model-in-the-Loop Enabled Training (HAMLET), a training procedure to automatically mitigate problems with current dataset collection procedures (see Figure 1).",

        "evidence": "According to CBO (and others), the precise reasons for the  rapid growth in income at the top are not well understood\",: xi  but involved multiple, possibly conflicting, factors.: xi \n\nCauses include:\n\ndecline of labor unions – Unions weakened in part due to globalization and automation may account for one-third to more than one-half of the rise of inequality among men. Pressure on employers to increase wages and on lawmakers to enact worker-friendly measures declined. Rewards from productivity gains went to executives, investors and creditors. A study by Kristal and Cohen reported that rising wage inequality was driven more by declining unions and the fall in the real value of the minimum wage, with twice as much impact as technology. An alternative theory states that passthrough income's contribution is incorrectly attributed to capital rather than labor.\nglobalization – Low skilled American workers lost ground in the face of competition from low-wage workers in Asia and other \"emerging\" economies.\nskill-biased technological change – Rapid progress in information technology increased the demand for skilled and educated workers.\nsuperstars – Modern communication technologies often turn competition into a \"winner take most\" tournament in which the winner is richly rewarded, while the runners-up get far less.\nfinancialization – In the 1990s stock market capitalization rose from 55% to 155% of Gross Domestic Product (GDP). Corporations began to shift executive compensation toward stock options, increasing incentives for managers to make decisions to increase share prices. Average annual CEO options increased from $500,000 to over $3 million. Stock comprised almost 50% of CEO compensation. Managers were incentivized to increase shareholder wealth rather than to improve long-term contracts with workers; between 2000 and 2007, nearly 75% of increased stock growth came at the cost of labor wages and salaries.\nimmigration of less-educated workers – Relatively high levels of immigration of low skilled workers since 1965 may have reduced wages for American-born high school dropouts;\ncollege premium - Workers with college degrees traditionally earned more and faced a lower unemployment rate than others. Wealthy families are also more likely to send their children to schools which have large endowments, resulting in more grants and lower student debt. The cycle is completed when wealthier alums donate more and disproportionately increase the size of elite endowments. Elite colleges also have better access to financial expertise.\nautomation - The Bureau of Labor Statistics (BLS) found that increased automation had led to \"an overall drop in the need for labor input. This would cause capital share to increase, relative to labor share, as machines replace some workers.\"\nWe haven't achieved the minimalist state that libertarians advocate. What we've achieved is a state too constrained to provide the public goods – investments in infrastructure, technology, and education – that would make for a vibrant economy and too weak to engage in the redistribution that is needed to create a fair society. But we have a state that is still large enough and distorted enough that it can provide a bounty of gifts to the wealthy.\n\n—Joseph Stiglitz\npolicy – Krugman asserted that movement conservatives increased their influence over the Republican Party beginning in the 1970s. In the same era, it increased its political power. The result was less progressive tax laws, anti-labor policies, and slower expansion of the welfare state relative to other developed nations (e.g., the unique absence of universal healthcare). Further, variation in income inequality across developed countries indicate that policy has a significant influence on inequality; Japan, Sweden and France have income inequality around 1960 levels. The US was an early adopter of neoliberalism, whose focus on growth over equality spread to other countries over time.\ncorporatism and corpocracy – Excessive attention to the interests of corporations reduced scrutiny over compensation shifts.\nfemale labor force participation – High earning households are more likely to be dual earner households.\nstock ownership is tilted towards households at higher income and education levels, resulting in disparate investment income.\nHigher income households are disproportionately likely to prosper when economic times are good, and to suffer losses during downturns. More of their income comes from relatively volatile capital income. For example, in 2011 the top 1% of income earners derived 37% of their income from labor, versus 62% for the middle quintile. The top 1% derived 58% of their income from capital as opposed to 4% for the middle quintile. Government transfers represented only 1% of the income of the top 1% but 25% for the middle quintile; the dollar amounts of these transfers tend to rise in recessions.\n\nAccording to a 2018 report by the Organization of Economic Cooperation and Development (OECD), the US has higher income inequality and a larger percentage of low income workers than almost any other advanced nation because unemployed and at-risk workers get less support from the government and a weak collective bargaining system.",

The hypothesis text is then constructed based on this premise text. There is either a binary or a tripartite classification of entailment — depending on the version of RTE. The first two RTE challenges follow the former scheme and make a binary classification of entailment (entailed or not entailed). Tripartite classification (entailment, negation of the hypothesis entailment or no entailment) is added in the later datasets, retaining two way classification versions as well. Seven RTE challenges have been created altogether.\nThe main advantages of the RTE challenges is their use of examples from natural text and the inclusion of cases that require presupposed information, mostly world knowledge. Indeed, the very definition of inference assumed in a number of the examples is problematic. As BIBREF1 have pointed out, RTE platforms suffer from cases of inference that should not be categorized as such. For these cases, a vast amount of world knowledge needs to be taken into consideration (that most importantly not every linguistic agent has). In this paper, and having the RTE as our starting point challenges, we claim that RTE is insufficiently precise to perform logical reasoning or precise reasoning tasks and we take up the task of validating our working hypothesis and proposing a method for doing proper collection of precise entailment pairs in the style of RTE. Of course, the creators of RTE had in mind a more loose definition of inference where both a precise and an imprecise definition of entailment would be at play. BIBREF2 mention that “our applied notion of textual entailment is also related, of course, to classical semantic entailment in the linguistics literature... a common definition of entailment specifies that a text t entails another text h (hypothesis, in our terminology) if h is true in every circumstance (possible world) in which t is true.\" This is close to what we want to capture in this paper. But, at the same time, BIBREF2 also mention that “however, our applied definition allows for cases in which the truth of the hypothesis is highly plausible, for most practical purposes, rather than certain\". It is these cases we want to make more precise, in the sense of making the supporting hidden inferences that are at play in many of the RTE examples explicit. In a way, what we are aiming at is a methodology of constructing entailment datasets in the style of RTE, that will involve a more precise definition of entailment and will further record any missing/hidden premises are used in justifying or not an entailment pattern.\nThe Recognizing Textual Entailment (RTE) challenges first appeared in 2004 as a means to test textual entailment, i.e. relations between a premise text and a hypothesis text (3): (3) An entailment example from RTE1.",

        "question": "Give me a short summary of the Industrial Revolution",
        "evidence": "The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines; new chemical manufacturing and iron production processes; the increasing use of water power and steam power; the development of machine tools; and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. The textile industry was the first to use modern production methods,  and textiles became the dominant industry in terms of employment, value of output, and capital invested.\n\nThe Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leading commercial nation, controlling a global trading empire with colonies in North America and the Caribbean. Britain had major military and political hegemony on the Indian subcontinent; particularly with the proto-industrialised Mughal Bengal, through the activities of the East India Company. The development of trade and the rise of business were among the major causes of the Industrial Revolution.\n\nThe Industrial Revolution marked a major turning point in history. Comparable only to humanity's adoption of agriculture with respect to material advancement, the Industrial Revolution influenced in some way almost every aspect of daily life. In particular, average income and population began to exhibit unprecedented sustained growth. Some economists have said the most important effect of the Industrial Revolution was that the standard of living for the general population in the Western world began to increase consistently for the first time in history, although others have said that it did not begin to meaningfully improve until the late 19th and 20th centuries. GDP per capita was broadly stable before the Industrial Revolution and the emergence of the modern capitalist economy, while the Industrial Revolution began an era of per-capita economic growth in capitalist economies. Economic historians are in agreement that the onset of the Industrial Revolution is the most important event in human history since the domestication of animals and plants.\n\nThe precise start and end of the Industrial Revolution is still debated among historians, as is the pace of economic and social changes.Eric Hobsbawm held that the Industrial Revolution began in Britain in the 1780s and was not fully felt until the 1830s or 1840s, while T. S. Ashton held that it occurred roughly between 1760 and 1830.Rapid industrialisation first began in Britain, starting with mechanized textiles spinning in the 1780s, with high rates of growth in steam power and iron production occurring after 1800. Mechanized textile production spread from Great Britain to continental Europe and the United States in the early 19th century, with important centres of textiles, iron and coal emerging in Belgium and the United States and later textiles in France.\n\nAn economic recession occurred from the late 1830s to the early 1840s when the adoption of the Industrial Revolution's early innovations, such as mechanized spinning and weaving, slowed and their markets matured. Innovations developed late in the period, such as the increasing adoption of locomotives, steamboats and steamships, and hot blast iron smelting. New technologies such as the electrical telegraph, widely introduced in the 1840s and 1850s, were not powerful enough to drive high rates of growth. Rapid economic growth began to occur after 1870, springing from a new group of innovations in what has been called the Second Industrial Revolution. These innovations included new steel making processes, mass production, assembly lines, electrical grid systems, the large-scale manufacture of machine tools, and the use of increasingly advanced machinery in steam-powered factories",

Given a set of tokens $\\mathbf {X}=(x_1,....,x_T)$, where $T$ is the length of a sequence, our task is to estimate the joint conditional probability $P(\\mathbf {X})$ which is\nwere $(x_{1}, \\ldots , x_{i-1})$ is the context. An Intrinsic evaluation of the performance of Language Models is perplexity (PPL) which is defined as the inverse probability of the set of the tokens and taking the $T^{th}$ root were $T$ is the number of tokens\nIn our two approaches we use transformer based architectures: BERT and Transformer-XL as mentioned before. Calculating the auto-regressive $P(\\mathbf {X})$ for the transformer-XL is quite straight-forward as the model is unidirectional but it doesn't factorize the same way for a bi-directional model like BERT.\nBERT's bi-directional context poses a problem for us to calculate an auto-regressive joint probability. A simple fix could be that we mask all the tokens $\\mathbf {x}_{>i}$ and we calculate the conditional factors as we do for an unidirectional model. By doing so though, we loose upon the advantage of bi-directional context the BERT model enables. We propose an approximation of the joint probability as,\nThis type of approximations has been previously explored with Bi-directional RNN LM's BIBREF9 but not for deep transformer models. We therefore, define a pseudo-perplexity score from the above approximated joint probability.\nThe original BERT has two training objectives: 'Masked language modelling', in which you mask input tokens randomly and then predict the masked tokens using the left and right context. Additionally, there is the 'next sentence prediction' task that jointly trains text-pair representations. For training the Masked language model the original BERT used Byte Pair Encoding (BPE) BIBREF10 for subword tokenization BIBREF11.For example the rare word \"unaffable\" to be split up into more frequent subwords such as [\"un\", \"##aff\", \"##able\"]. To remain consistent with experiments performed with LSTM's we use the morfessor for the subword tokenization in the Finnish Language. In Addition, we also apply boundary markers as in (Table TABREF7) and train two separate models using this distinction. We train with left-marked markings as the original BERT was trained with such a scheme and the left+right-marked as it was the previous SOTA with the Finnish Language. For the transformer-XL experiments, we just train with the left+right marked scheme.\nThe Next Sentence Prediction (NSP) is a binary classification task which predicts whether two segments follow each other in the original text. This pre-training task was proposed to further improve the performance on downstreaming tasks, like Natural Language Inference(NLI) but in reality removing the NSP loss matches or slightly improves the downstream task performance BIBREF12. In this paper, we have omitted the NSP task from the BERT pre-training procedure and changed the input from a SEGMENT-PAIR input to a SINGLE SEGMENT input. As seen in (Fig FIGREF8)\nTransformer-XL introduced the notion of recurrence in self-attention by caching the hidden state sequence to compute the hidden states of a new segment. It also introduces a novel relative positional embedding scheme and both of them combined address the issue of fixed context lengths. Transformer-XL as mentioned is a unidirectional deep transformer architecture, therefore the perplexity can be calculated as (Eq DISPLAY_FORM5). The only change is in the input format, were we use sub-word units rather than whole word units as Finnish is morphologically richer than English.\nIn our two approaches we use transformer based architectures: BERT and Transformer-XL as mentioned before.",

        "evidence": "Deep learning models have been widely used in many natural language processing (NLP) tasks. A major challenge is how to design and learn the semantic composition function while modeling a text sequence. The typical composition models involve sequential BIBREF0 , BIBREF1 , convolutional BIBREF2 , BIBREF3 , BIBREF4 and syntactic BIBREF5 , BIBREF6 , BIBREF7 compositional models.\nIn spite of their success, these models have two major limitations. First, they usually use a shared composition function for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Second, different composition functions are learned from scratch in different tasks. However, given a certain natural language, its composition functions should be the same (on meta-knowledge level at least), even if the tasks are different.\nTo address these problems, we need to design a dynamic composition function which can vary with different positions and contexts in a sequence, and share it across the different tasks. To share some meta-knowledge of composition function, we can adopt the multi-task learning BIBREF8 . However, the sharing scheme of most neural multi-task learning methods is feature-level sharing, where a subspace of the feature space is shared across all the tasks. Although these sharing schemes are successfully used in various NLP tasks BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , they are not suitable to share the composition function.\nIn this paper, inspired by recent work on dynamic parameter generation BIBREF15 , BIBREF16 , BIBREF17 , we propose a function-level sharing scheme for multi-task learning, in which a shared meta-network is used to learn the meta-knowledge of semantic composition among the different tasks. The task-specific semantic composition function is generated by the meta-network. Then the task-specific composition function is used to obtain the task-specific representation of a text sequence. The difference between two sharing schemes is shown in Figure 1 . Specifically, we use two LSTMs as meta and basic (task-specific) network respectively. The meta LSTM is shared for all the tasks. The parameters of the basic LSTM are generated based on the current context by the meta LSTM, therefore the composition function is not only task-specific but also position-specific. The whole network is differentiable with respect to the model parameters and can be trained end-to-end.\nWe demonstrate the effectiveness of our architectures on two kinds of NLP tasks: text classification and sequence tagging. Experimental results show that jointly learning of multiple related tasks can improve the performance of each task relative to learning them independently.\nOur contributions are of three-folds:\nThen the task-specific composition function is used to obtain the task-specific representation of a text sequence.",

Only by exploiting cross-lingual transfer learning techniques BIBREF5 , BIBREF6 , BIBREF7 , can the NMT performance approach PBSMT performance in low-resource scenarios.\nHowever, such methods usually require an NMT model trained on a resource-rich language pair like French INLINEFORM0 English (parent), which is to be fine-tuned for a low-resource language pair like Uzbek INLINEFORM1 English (child). On the other hand, multilingual approaches BIBREF8 propose to train a single model to translate multiple language pairs. However, these approaches are effective only when the parent target or source language is relatively resource-rich like English (En). Furthermore, the parents and children models should be trained on similar domains; otherwise, one has to take into account an additional problem of domain adaptation BIBREF9 .\nIn this paper, we work on a linguistically distant and thus challenging language pair Japanese INLINEFORM0 Russian (Ja INLINEFORM1 Ru) which has only 12k lines of news domain parallel corpus and hence is extremely resource-poor. Furthermore, the amount of indirect in-domain parallel corpora, i.e., Ja INLINEFORM2 En and Ru INLINEFORM3 En, are also small. As we demonstrate in Section SECREF4 , this severely limits the performance of prominent low-resource techniques, such as multilingual modeling, back-translation, and pivot-based PBSMT.

Instantiating this concept with the signalling game design from enables linguists to explore the emergence of linguistic structure where artificial languages are represented as symbolic systems. The success of deep learning (DL) models on complicated cognitive tasks then inspired researchers to apply DL-based models to language games to investigate the agents' ability to invent communication protocols without preset rules (e.g..\nIn the existing works (e.g., there are usually two types of agents, speakers that emit messages based on their observations (i.e. input target objects) and listeners that receive messages and act accordingly, as illustrated in Figure. Based on the goals for listeners, we can categorise most of the games into the following three types: 1) referential games in which listeners need to select the target object observed by the speaker among a set of candidate objects (candidates for short) (e.g.; 2) reconstruction games in which listeners need to reconstruct the speaker's observation (e.g. ; and 3) navigation games in which listeners need to go to the location specified by speakers (e.g.. We focus on referential games, illustrated in Figure, which have been well investigated in both the linguistic community (e.g. and emergent communication community (e.g..\nIt is reasonable to assume that listeners in referential games can differentiate the target object from the other distractors in the context as long as the speaker's message encodes some unique feature of the target. Therefore, the speaker's messages must convey a different amount of information for listeners to complete their task in games where candidates are similar in different degrees. For example, to distinguish two very similar candidates, e.g. blue wide-stripped shirt and blue narrow-stripped shirt, it requires more information about the target to be encoded by the speaker's message than to distinguish a shirt from a cup. Experiments with human participants show that emergent languages are sensitive to the requirements of the communicative tasks for which they are used, with languages developing in which only the necessary discriminatory information is encoded.\n˚Correspondence author, e-mail address: s.guo@ed.ac.uk   Following, we refer to such ability to encode information about input space (e.g. structure, dimensionality, distribution of samples) as expressivity. In this work, we explore the factors that influence expressivity in the framework of DL-based referential games, and we argue that it is important to understand these factors such that agents could develop languages that are effective enough for completing various tasks.\nOur contribution in this work is threefold. First, we propose and verify a hypothesis about the determining factors of expressivity of emergent languages under the DL-based framework. Following, we show that context size (i.e. the number of candidates the listener must select among when interpreting the speaker's message) influence both the complexity and unpredictability of that context. Complexity refers to the similarity between the items in the context: in order for the listener to select the target, more information needs to be encoded in the speaker's signal if the context contains more similar distractors for a given target. Unpredictability refers to the extent to which the information that needs to be encoded by the speaker is stable across contexts in successive episodes of communication: in games where the information required by the listener differs from trial (training epoch for DL agents) to trial, the speaker needs to encode more information on every trial in order to be sure to encode the information the listener needs. As we show in Section 3.1, complexity and unpredictability are affected differently by the context size: as context size increases, complexity increases but unpredictability decreases. Therefore, we propose and verify the following hypothesis about the determining factors of expressivity:\n[HYPOTHESIS] The expressivity of emergent languages is a trade-off between the complexity and the unpredictability of context in language games.\n[1]\nOur second contribution is a novel measure of expressivity based on partial ordering of languages in terms of their generalisation performances across tasks. Although expressivity is related to the amount of information encoded in a language, we illustrate that mutual information (MI) is not an appropriate measurement for expressivity in Section 3.2. Considering that one of our objectives is to facilitate a universally useful emergent language, we propose to measure expressivity of a language based on the generalisation performance of listening agents trained with that language across different games. Since it is more challenging to quantitatively and directly measure expressivity, we focus on the partial ordering between languages in this first step towards understanding expressivity.\nOur final contribution is the discovery of message type collapse, i.e. the number of unique messages is significantly lower than the size of input space in relatively easy games, which can lead to highly ambiguous emergent languages. To overcome the technical limitations imposed by GPU memory size on large-scale referential games, we introduce the contrastive loss proposed by in referential games. While comparing the behaviour of the contrastive loss and the loss function used in previous works (e.g, we find that this contrastive loss can greatly alleviate the collapse of message types, leading to more disambiguous and potentially more expressive emergent languages.\nAs we show in Section 3.1,complexity and unpredictability are affected differently by the context size: as context size increases,complexity increases but unpredictability decreases.",

BIBREF8 have shown that trading volumes of stocks traded in NASDAQ-100 are correlated with their query volumes (i.e., the number of users requests submitted to search engines on the Internet). Gilbert and Karahalios BIBREF9 have found out that increases in expressions of anxiety, worry and fear in weblogs predict downward pressure on the S&P 500 index.

Documents that contain bidirectional words (`associate', `relate', `connect', `correlate', and any of their stems) were also not selected for analysis. This is because our focus is on causality, an inherently one-sided relationship between two objects. We also did not consider additional synonyms of these cause words, although that could be pursued for future work. Control documents were also selected. These documents did not contain any of `caused', `causing', or `causes', nor any bidirectional words, and are further matched temporally to obtain the same number of control documents as causal documents in each fifteen-minute period during 2013. Control documents were otherwise selected randomly; causal synonyms may be present. The end result of this procedure identified 965,560 causal and 965,560 control documents. Each of the three “cause-words”, `caused', `causes', and `causing' appeared in 38.2%, 35.0%, and 26.8% of causal documents, respectively.\nCausal documents were chosen to contain one occurrence only of the exact unigrams: `caused', `causing', or `causes'.",

        "question": "Where does the final representation of the user is fed to?",
        "answer": "To a fully connected layer for prediction.",
        "evidence": "Author profiling is the characterization of an author through some key attributes such as gender, age, and language. It's an indispensable task especially in security, forensics, and marketing. Recently, social media has become a great data source for the potential learning approaches. Furthermore, gender prediction has been a popular profiling task.\nThe traditional approach to gender prediction problem is extracting a useful set of hand-crafted features and then feeding them into a standard classification algorithm. In their study, BIBREF0 work with the style-based features of message length, stop word usage, frequency of smiley etc. and use different classifiers such as k-nearest neighbor, naive bayes, covering rules, and backpropagation to predict gender on chat messages. Similarly, BIBREF1 select some hand-crafted features and feed them into various classifiers.\nMost of the work on gender prediction rely on n-gram features BIBREF2. BIBREF3 give Latent Semantic Analysis (LSA)-reduced forms of word and character n-grams into Support Vector Machine (SVM) and achieve state-of-the-art performance. Apart from exploiting n-gram frequencies, there are studies BIBREF4, BIBREF5, BIBREF6 to extract cross-lingual features to determine gender from tweets. Some other work BIBREF4, BIBREF7 exploit user metadata besides using just tweets.\nRecently, neural network-based models have been proposed to solve this problem. Rather than explicitly extracting features, the aim is to develop an architecture that implicitly learns. In author profiling, both style and content-based features were proved useful BIBREF8 and neural networks are able to capture both syntactic and semantic regularities. In general, syntactic information is drawn from the local context. On the other hand, semantic information is often captured with larger window sizes. Thus, CNNs are preferred to obtain style-based features while RNNs are the methods of choice for addressing content-based features BIBREF9. In literature, CNN BIBREF10 or RNN BIBREF11, BIBREF12, BIBREF13 is used on this task. BIBREF11 obtain state-of-the-art performance among neural methods by proposing a model architecture where they process text through RNN with GRU cells. Also, the presence of an attention layer is shown to boost the performance of neural methods BIBREF11, BIBREF10.\nIn this work, we propose a model that relies on RNN with attention mechanism (RNNwA). A bidirectional RNN with attention mechanism both on word level and tweet level is trained with word embeddings. The final representation of the user is fed to a fully connected layer for prediction. Since combining some hand-crafted features with a learned linear layer has shown to perform well in complex tasks like Semantic Role Labeling (SRL) BIBREF14, an improved version of the model (RNNwA + n-gram) is also tested with hand-crafted features. In the improved version, LSA-reduced n-gram features are concatenated with the neural representation of the user. Then the result is fed into a fully-connected layer to make prediction. Models are tested in three languages; English, Spanish, and Arabic, and the improved version achieves state-of-the-art accuracy on English, and competitive results on Spanish and Arabic corpus.\nThere are many datasets created for this task BIBREF15, BIBREF16. In this work, we have used the dataset and benchmarks provided by the PAN 2018 shared task on author profiling BIBREF15. As the dataset contains a constant number of 100 tweets per user, accuracy tests are performed both on user and tweet level (tweet-level predictions are made by removing the user-level attention). Tweet-level accuracy tests show interesting results during hyperparameter optimization. When the tweet-level predictions are averaged to produce user-level predictions, it is seen that the hyperparameters that gave the best results in terms of tweet-level accuracy, performs worse in user-level accuracy. The better user-level models, with different hyperparameters, that gave the highest user-level accuracy are observed to slightly overfit on tweet-level. It leads us to believe that the overfitting in the tweet-level predictions in best user-level models acts similar to an attention mechanism by over-emphasizing some distinctive tweets and ignoring the rest.\nThe final representation of the user is fed to a fully connected layer for prediction.",

These issues can be summarized into two parts: ambiguity and coarseness.\nFirst, the extracted entities may be ambiguous. In the example, the entity “South Korean” is ambiguous because it can refer to both the South Korean person and the South Korean language, among others. In our experimental data, we extract (1) the top 100 entities based on frequency, and (2) the entities extracted from 100 randomly selected texts, and check whether they have disambiguation pages in Wikipedia or not. We discover that $71.0\\%$ of the top 100 entities and $53.6\\%$ of the entities picked at random have disambiguation pages, which shows that most entities are prone to ambiguity problems.\nSecond, the linked entities may also be too common to be considered an entity. This may introduce errors and irrelevance to the summary. In the example, “Wednesday” is erroneous because it is wrongly linked to the entity “Wednesday Night Baseball”. Also, “swap” is irrelevant because although it is linked correctly to the entity “Trade (Sports)”, it is too common and irrelevant when generating the summaries. In our experimental data, we randomly select 100 data instances and tag the correctness and relevance of extracted entities into one of four labels: A: correct and relevant, B: correct and somewhat relevant, C: correct but irrelevant, and D: incorrect. Results show that $29.4\\%$ , $13.7\\%$ , $30.0\\%$ , and $26.9\\%$ are tagged with A, B, C, and D, respectively, which shows that there is a large amount of incorrect and irrelevant entities.\nDespite its usefulness, linked entities extracted from ELS’s have issues because of low precision rates (Hasibi et al., 2016) and design challenges in training datasets (Ling et al., 2015).

        "evidence": "In this section, we show the model performances of our proposed crowdsourcing learning system (ALCrowd), and meanwhile compare it with the other systems mentioned above. Table 2 shows the experimental results on the DL-PS datasets and Table 3 shows the experiment results on the EC-MT and EC-UQ datasets, respectively.\nThe results of CRF and LSTM-CRF mean that the crowd annotation is an alternative solution with low cost for labeling data that could be used for training a NER system even there are some inconsistencies. Compared with CRF, LSTM-CRF achieves much better performances on all the three data, showing +6.12 F1 improvement on DL-PS, +4.51 on EC-MT, and +9.19 on EC-UQ. This indicates that LSTM-CRF is a very strong baseline system, demonstrating the effectiveness of neural network.\nInterestingly, when compared with CRF and LSTM-CRF, CRF-VT and LSTM-CRF-VT trained on the voted version perform worse in the DL-PS dataset. This trend is also mentioned in BIBREF4 nguyen2017aggregating. This fact shows that the majority voting method might be unsuitable for our task. There are two possible reasons accounting for the observation. On the one hand, simple character-level voting based on three annotations for each sentence may be still not enough. In the DL-PS dataset, even with only two predefined entity types, one character can have nine NE labels. Thus the majority-voting may be incapable of handling some cases. While the cost by adding more annotations for each sentence would be greatly increased. On the other hand, the lost information produced by majority-voting may be important, at least the ambiguous annotations denote that the input sentence is difficult for NER. The normal CRF and LSTM-CRF models without discard any annotations can differentiate these difficult contexts through learning.\nThree crowd-annotation learning systems provide better performances than their counterpart systems, (CRF-MA VS CRF) and (LSTM-Crowd/ALCrowd VS LSTM-CRF). Compared with the strong baseline LSTM-CRF, ALCrowd shows its advantage with +1.08 F1 improvements on DL-PS, +1.24 on EC-MT, and +2.38 on EC-UQ, respectively. This indicates that adding the crowd-annotation learning is quite useful for building NER systems. In addition, ALCrowd also outperforms LSTM-Crowd on all the datasets consistently, demonstrating the high effectiveness of ALCrowd in extracting worker independent features. Among all the systems, ALCrowd performs the best, and significantly better than all the other models (the p-value is below $10^{-5}$ by using t-test). The results indicate that with the help of adversarial training, our system can learn a better feature representation from crowd annotation.\nAmong all the systems, ALCrowd performs the best, and significantly better than all the other models (the p-value is below 10−5 by using t-test).",

        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results.",

The second extends the complex partial-order structure of real-world ontologies to find long-distance triplet constraints among embeddings which are poorly enforced by the standard pairwise training method.",
        "evidence": "A core problem in artificial intelligence is to capture, in machine-usable form, the collection of information that an ordinary person would have, known as commonsense knowledge. For example, a machine should know that a room may have a door, and that when a person enters a room, it is generally through a door. This background knowledge is crucial for solving many difficult, ambiguous natural language problems in coreference resolution and question answering, as well as the creation of other reasoning machines.\nMore than just curating a static collection of facts, we would like commonsense knowledge to be represented in a way that lends itself to machine reasoning and inference of missing information. We concern ourselves in this paper with the problem of learning commonsense knowledge representations.\nIn machine learning settings, knowledge is usually represented as a hypergraph of triplets such as Freebase BIBREF1 , WordNet BIBREF2 , and ConceptNet BIBREF3 . In these knowledge graphs, nodes represent entities or terms $t$ , and hyperedges are relations $R$ between these entities or terms, with each fact in the knowledge graph represented as a triplet $<t_1, R, t_2>$ . Researchers have developed many models for knowledge representation and learning in this setting BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , under the umbrella of knowledge graph completion. However, none of these naturally lend themselves to traditional methods of logical reasoning such as transitivity and negation.\nWhile a knowledge graph completion model can represent relations such as Is-A and entailment, there is no mechanism to ensure that its predictions are internally consistent. For example, if we know that a dog is a mammal, and a pit bull is a dog, we would like the model to also predict that a pit bull is a mammal. These transitive entailment relations describe ontologies of hierarchical data, a key component of commonsense knowledge which we focus on in this work.\nRecently, a thread of research on representation learning has aimed to create embedding spaces that automatically enforce consistency in these predictions using the intrinsic geometry of the embedding space BIBREF9 , BIBREF0 , BIBREF10 . In these models, the inferred embedding space creates a globally consistent structured prediction of the ontology, rather than the local relation predictions of previous models.\nWe focus on the order-embedding model BIBREF0 which was proposed for general hierarchical prediction including multimodal problems such as image captioning. While the original work included results on ontology prediction on WordNet, we focus exclusively on the model's application to commonsense knowledge, with its unique characteristics including complex ordering structure, compositional, multi-word entities, and the wealth of commonsense knowledge to be found in large-scale unstructured text data.\nWe propose two extensions to the order embedding model. The first augments hierarchical supervision from existing ontologies with non-hierarchical knowledge in the form of raw text. We find incorporating unstructured text brings accuracy from 92.0 to 93.0 on a commonsense dataset containing Is-A relations from ConceptNet and Microsoft Concept Graph (MCG), with larger relative gains from smaller amounts of labeled data.\nThe second extension uses the complex partial-order structure of real-world ontologies to find long-distance triplet constraints among embeddings which are poorly enforced by the standard pairwise training method. By adding our additional triplet constraints to the baseline order-embedding model, we find performance improves from 90.6 to 91.3 accuracy on the WordNet ontology dataset.\nWe find that order embeddings' ease of extension, both by incorporating non-ordered data, and additional training constraints derived from the structure of the problem, makes it a promising avenue for the development of further algorithms for automatic learning and jointly consistent prediction of ontologies.\nWe propose two extensions to the order embedding model.

        "answer": "This is correct! Pretraining is no cure-all, and we believe applications that feature task ambiguity (which may manifest through distribution shift) are one of the most important outstanding challenges. To capture the precise effect of these shifts, we conduct a \"dose-response\" experiment where we vary the fraction of mismatched examples in Waterbirds from 5% to 50%. See the main comment for more details.",
        "evidence": "Modern pretrained models can be adapted to new tasks with remarkably little data, enabling downstream applications for tasks with only tens or hundreds of examples. However, an important but neglected challenge that is especially salient in few-shot settings is task ambiguity, when the desired behavior is not uniquely specified by the provided examples. Task ambiguity can manifest in different ways: For example, the class-relevant features of an input (e.g., the shape of an object in Figure) may be spuriously correlated with other features predictive of the training labels (e.g., the color of the object), making the desired task unclear. In addition, task ambiguity may arise from an underdiverse training set, causing models to be unsure of the desired behavior for minority groups or during distribution shifts that occur at test-time.\nWe consider whether the task ambiguity problem can be addressed through active learning, where models select informative examples for users to label. In principle, active learning allows models themselves to assist in resolving task ambiguity by identifying examples whose labels would be informative; for example, in fig., asking for the label of the blue square helps determine that the desired task is to predict the object shape not the object color. Since it may be challenging in general for users to intuit possible sources of task ambiguity, much less how to address them with example selection, an automated active learning approach may be desirable.\nIn traditional settings with smaller, unpretrained models, several challenges often prevent active learning from seeing success in practice, including label noise, unlearnable examples, and a lack of generalizability across models and tasks. However, using pretrained models in few-shot or low-data settings has several key differences from traditional ML pipelines which may make them particularly well-suited for active learning. First, the effect of an individual data point (and the difference between an informative vs. an uninformative one) is magnified, compared to the thousands or millions of examples typically acquired through standard active learning pipelines. Second, pretrained models excel at learning high-level representations of inputs, which better surface relevant features and may encourage active learning to select examples that disambiguate between these high-level features (e.g. shape and color).\nWe consider the use of active learning on a range of spuriously correlated, imbalanced, or domain shifted datasets where task ambiguity is salient. We compare an active learning approach with a random-sampling baseline, and compare the difference in performance with and without the use of pretrained models. Our contributions are:\n1. Identifying and motivating task ambiguity as a unified concern across a range of real-world datasets, and an especially salient problem for low-data settings.\n2. Proposing active learning as a potential solution, along with a simple yet practical recipe that does not require adjustment for new datasets or tuning on validation data.\n3. Showing that active learning can enable large gains (up to 6× reduction in data points, +12% absolute gain for the same labeling budget) and presenting scaling trends demonstrating that this is an emergent property of pretraining.\nTo examine the impact of task ambiguity from the perspective of the unlabeled dataset, we construct variants of the waterbirds dataset where the percentage of mismatched examples range from 95% to 50%. 4 We then proceed with AL and report results in Figure. 5 We find significantly larger gains on versions of the dataset with smaller fraction of mismatched examples (gains average 4% for 50-70% shift, and 10% for 75-95% shift) keeping. This provides stronger evidence that active learning is actually helping the model identify the true task.\nHowever, an important but neglected challenge that is especially salient in few-shot settings is task ambiguity, when the desired behavior is not uniquely specified by the provided examples.****To examine the impact of task ambiguity from the perspective of the unlabeled dataset, we construct variants of the waterbirds dataset where the percentage of mismatched examples range from 95% to 50%.",

        "evidence": "Deep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available. However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nOur analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.",

Also, we wanted to be clear about the firm’s north star, which is improved customer experience, efficient and reliable operations with low cost, and minimal environmental impact. \n\nUber’s business model: \n\nValue proposition:  \n\nUber’s value prop is to offer transportation services via internet orderings from the customer. Customers order a transportation service via a mobile-enabled app and get instant or real-time updates about the order status. This significantly differs from the current taxi-cab model, where customers must hire a taxi-cab by waiting in line at the airport or taxi station. The existing taxi hire model has a poor experience for customers and comes with a high cost. \n\nActivities, resources, and capabilities: \n\nThe critical activity for Uber in this business model is to connect the passengers and drivers on a demand basis concerning a location with a computer algorithm and deliver the service over a mobile app for both drivers and passengers. \n\nUber needs computational resources and engineers to build the algorithm. Also, Uber needs to develop capabilities to attract drivers and passengers to its platform for each market, country, and city. \n\nRevenue model: \n\nIn this model, Uber customers will pay per hire, which will include the transportation charge, driver’s labor fees, and the driver’s car maintenance, including fuel and running and maintenance expenses of the car, and a small commission for Uber that will be the revenue for the company. On average per ride, Uber expects to earn a 3% commission for basic taxi-hire service. Top-of-the-line services like Uber-X may earn up to 10% commission. \n\nScope of the enterprise: \n\nThis business model's primary customer segment is millennials with smartphones with internet-enabled services. \n\n \n\nThis business model's horizontal scope can be vastly expanded to different products. Uber can start with a standard taxi-hire service, and for the luxury segment, it can offer Uber-X and Uber-SUV. Uber can also branch to adjacent industries like food delivery with Uber Eats and freight delivery with Uber Freight. \n\n \n\nThe business’s sheer scope is to develop the in-house demand algorithm for connecting drivers and passengers. Uber does not intend to employ drivers. Instead, it will lease/contract the drivers on a per-ride basis and pay the contract cost to the drivers. In contrast, the computational and other IT infrastructure services will be leased/rented on services like Amazon Web Services or Microsoft Azure. This will enable Uber to be agile and move fast in various markets while protecting its intellectual property, the algorithm.",

        "question": "Write a letter to my mum and dad detailing the reasons why they should buy me a pet tortoise",
        "evidence": "",
        "answer": "Dear Mum and Dad,\n\nAs you know, I have wanted a pet tortoise for some time now. I have given it a lot of thought and done a great deal of research into what might be involved. I am aware that having a pet is a huge commitment so I am writing to you to explain why I think you should buy me a pet tortoise and why a tortoise is a fantastic choice of pet.\n\nLooking after a pet tortoise will give me a strong sense of responsibility. I know that I will have to ensure my tortoise is well fed, kept at the right temperature, given opportunities to bask under a heated lamp or in the sunshine if warm enough. I am very willing to give the time and commitment necessary to look after my tortoise. The tortoise will be my sole responsibility and I feel mature enough to commit to its care and happiness.\n\nAs you know, I suffer from anxiety and school makes me particularly worried sometimes. It has been shown through numerous studies that pets reduce anxiety and stress in humans. I feel sure that having a tortoise will be a fantastic distraction from my worries and bring me great enjoyment. Contrary to popular belief, tortoises love having their shells stroked and their chins tickled and I think it would be very relaxing for me to pet a tortoise when I get home from school.\n\nTortoises are very self-sufficient. Provided they are given a warm place to bask, access to fresh water and plenty of fresh food such as dandelions, kale, lettuce and other leafy vegetables, they are very happy to be left to their own devices. As we live in the UK where temperatures can be cool, we would need to purchase a tortoise table with good substrate, a basking lamp and some hides where the tortoise can tuck itself away. We have lots of space for this in our kitchen. When it is warm, the tortoise can go into our garden in an enclosure. A tortoise table and lamp will cost about £200 but this is just an initial outlay. Thereafter, keeping a tortoise is very cheap. In fact, you can pick most of their food for free by foraging which I am happy to do when we go for families walk.\n\nContrary to popular belief, tortoises can be very friendly. As I have mentioned above, they love being stroked but did you also know that they can recognise their owners and some can even respond to their names? In fact, a study showed that tortoises can recognise their previous owners that they haven’t seen in years so they are both friendly and very intelligent.\nYou might be worried about hibernating a tortoise but I have done lots of research on this and now know exactly what to do. If we buy a tortoise, it will need to hibernate for a maximum of three months from the end of September. We will need to hibernate our tortoise in a well-insulated box. The temperature mustn’t go above or below 5 degrees celsius and our garage would be the perfect place for it. We have a temperature gauge in there so I can keep an eye on the heat levels. \n\nFinally, I have looked into the cost of buying a tortoise. I would suggest we buy a tortoise which is a couple of years’ old as they require less care. We can buy a preloved tortoise which has been microchipped for about £100. And when we go on holiday, I have found a Tortoise Hotel which is run by a vet and costs just £60 for a 10 day stay.\n\nI think you will agree that I have conducted very thorough research into looking after a tortoise and I hope you will agree that I am now mature enough to look after a pet. I truly believe that a pet tortoise will give me a strong sense of responsibility and will have a positive calming effect on my mood. Indeed, I think the whole family will enjoy having a tortoise. They are friendly, loving, interesting and intelligent animals and we will all benefit from having one.\n\nI would be grateful if you would give my request full consideration.\n\nLots of Love,\n\nWilf x",

As to my heart, I belong entirely to the Heart of Jesus.\" Fluent in five languages – Bengali, Albanian, Serbian, English and Hindi – she made occasional trips outside India for humanitarian reasons. At the height of the Siege of Beirut in 1982, Mother Teresa rescued 37 children trapped in a front-line hospital by brokering a temporary cease-fire between the Israeli army and Palestinian guerrillas. Accompanied by Red Cross workers, she travelled through the war zone to the hospital to evacuate the young patients. When Eastern Europe experienced increased openness in the late 1980s, Mother Teresa expanded her efforts to Communist countries which had rejected the Missionaries of Charity. She began dozens of projects, undeterred by criticism of her stands against abortion and divorce: \"No matter who says what, you should accept it with a smile and do your own work.\" She visited Armenia after the 1988 earthquake and met with Soviet Premier Nikolai Ryzhkov. Mother Teresa travelled to assist the hungry in Ethiopia, radiation victims at Chernobyl and earthquake victims in Armenia. In 1991 she returned to Albania for the first time, opening a Missionaries of Charity Brothers home in Tirana. By 1996, the Missionaries of Charity operated 517 missions in over 100 countries. The number of sisters in the Missionaries of Charity grew from twelve to thousands, serving the \"poorest of the poor\" in 450 centres worldwide.

        "question": "How did the authors perform adversarial training?",
        "answer": "The authors perform adversarial training between the basic NER and an additional worker discriminator.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator.",

        "evidence": "Like the Battles of Marathon and Thermopylae, Salamis has gained something of a 'legendary' status (unlike, for instance, the more decisive Battle of Plataea), perhaps because of the desperate circumstances and the unlikely odds. A significant number of historians have stated that Salamis is one of the most significant battles in human history (though the same is often stated of Marathon). In a more extreme form of this argument, some historians argue that if the Greeks had lost at Salamis, the ensuing conquest of Greece by the Persians would have effectively stifled the growth of Western Civilization as we know it. This view is based on the premise that much of modern Western society, such as philosophy, science, personal freedom and democracy are rooted in the legacy of Ancient Greece. Thus, this school of thought argues that, given the domination of much of modern history by Western Civilization, Persian domination of Greece might have changed the whole trajectory of human history. It is also worth mentioning that the celebrated blossoming of hugely influential Athenian culture occurred only after the Persian wars were won.\n\nFrom: https://en.wikipedia.org/wiki/Battle_of_Salamis",
        "answer": "The battle (fought between the Persian Empire and Greek City-States in 480 BC) is still considered by many historians to be a foundational event in the development of Western Civilization and modern Democracy.  Some say that if the Greeks had lost at Salamis it could have had profound effects on the trajectory of human history.  Historian's trace back much of today's Western ideals in philosophy, culture, politics, and science to Ancient Greece.  They deduce that if Persia had won the Greco-Persian wars it could have oppressed the blossoming of many modern Western schools of thought.  \n\nSalamis is one of many skirmishes fought over the course of almost half a century during this conflict.  There were other pivotal battles that contributed to the Greek victory, like Marathon and Plataea.  However, if Salamis had been won by the Persians, the Greek navy would have been unable to stop them from establishing beachheads across Greece.  Much of the Greek victory has been attributed to their use of the environment to their advantage; leveraging natural chokepoints (like at Salamis) to reduce the effectiveness of Persia's numerical advantage.  Had Salamis fallen to the Persians it's reasonable to assume that this strategy would have failed and Persia's massive armies would have been able to dominate the Greeks.  \n\nIt's also impossible to predict the outcome of the war if Persia had won this battle, even though chances are things would have ended very differently.  Salamis is perhaps more highly regarded because of the long odds the Greek navy faced.  They were able to prevail despite being largely outnumbered, which could also be why it's considered such a remarkable event.",

In comparison to other Islamic extremist groups, ISIS' use of technology was more sophisticated, voluminous, and targeted. For example, during ISIS' advance toward Mosul, ISIS related accounts tweeted some 40,000 tweets in one day BIBREF0.However, this heavy engagement forced social media platforms to institute policies to prevent unchecked dissemination of terrorist propaganda to their users, forcing ISIS to adapt to other means to reach their target audience.\nOne such approach was the publication of online magazines in different languages including English. Although discontinued now, these online resources provided a window into ISIS ideology, recruitment, and how they wanted the world to perceive them. For example, after predominantly recruiting men, ISIS began to also include articles in their magazines that specifically addressed women. ISIS encouraged women to join the group by either traveling to the caliphate or by carrying out domestic attacks on behalf of ISIS in their respective countries. This tactical change concerned both practitioners and researchers in the counterterrorism community. New advancements in data science can shed light on exactly how the targeting of women in extremist propaganda works and whether it differs significantly from mainstream religious rhetoric.\nWe utilize natural language processing methods to answer three questions:\nWhat are the main topics in women-related articles in ISIS' online magazines?\nWhat similarities and/or differences do these topics have with non-violent, non-Islamic religious material addressed specifically to women?\nWhat kind of emotions do these articles evoke in their readers and are there similarities in the emotions evoked from both ISIS and non-violent religious materials?\nAs these questions suggest, to understand what, if anything, makes extremist appeals distinctive, we need a point of comparison in terms of the outreach efforts to women from a mainstream, non-violent religious group. For this purpose, we rely on an online Catholic women's forum. Comparison between Catholic material and the content of ISIS' online magazines allows for novel insight into the distinctiveness of extremist rhetoric when targeted towards the female population. To accomplish this task, we employ topic modeling and an unsupervised emotion detection method.\nThe rest of the paper is organized as follows: in Section SECREF2, we review related works on ISIS propaganda and applications of natural language methods. Section SECREF3 describes data collection and pre-processing. Section SECREF4 describes in detail the approach.

        "evidence": "Thysanozoon nigropapillosum is a species of polyclad flatworms belonging to the family Pseudocerotidae.  Some common names include gold-speckled flatworm, marine flatworm, yellow papillae flatworm, yellow-spotted flatworm, and yellow-spotted polyclad flatworm.Thysanozoon nigropapillosum has a long body and broad shape. They grow up to 3 in (76 mm).  The dorsal surface is deep black and covered with numerous yellow-tipped papillae varying in size. The ventral surface is dark brown. The outer margin of the body is slightly wavy and bordered in opaque white.  They have small, ear-like pseudotentacles in the middle of the anterior end. They swim by propelling themselves through the water with a rhythmic undulating motion of the body.This species is widespread in the tropical Indo-Pacific.Thysanozoon nigropapillosum is quite common along the external reef in the shallow sub-tidal zone. It can swim by undulating and rhythmically contracting the body margins. It feeds on tunicates, using its mouth and large pharynx to engulf Didemnum spp., and later regurgitates food pellets containing the calcareous spicules present in their tunics. Polyclad flatworms are hermaphrodites, with each one of a pair of flatworms trying to inseminate the other. Transfer of sperm may be by hypodermic insemination, but this is made difficult in this species by the presence of the papillae, and dermal impregnation often occurs. This involves sperm entering the body directly after being placed in the marginal region of the skin. Such dermal insemination is facilitated by the fact that the flatworm has two penises which are strengthened by the presence of rhabdites, and these can grip the margin of the partner and keep hold, even while the recipient is swimming.World Database of Marine SpeciesSeaslugsWormsZipcodezooGwannonPhotos of Thysanozoon nigropapillosum on Sealife Collection",

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nSecond, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language.",

One summer day, while resting indolently with the King in the main hall of the royal palace, the Queen suddenly had a thought. \"How nice it would be, King, if we could build some beautiful statutes of Lord Jagannath so that the people can come worship Jagannath, Balabhadra, and Subadhra. What do you think?\" \n\nThe King thought for a few minutes, and then nodded in agreement. \"What do you have in mind, my Queen?\" And so, soon the stone sculptor was summoned to appear before the Court for an appointment to build in his way the statutes of the gods. Soon the monsoon season started and the sculptor appeared in front of the court, awaiting his appointment. He was a humble man from the mountainous regions of Odisha. Even at his best-dressed, one couldn't help but notice his rough hands, and the small sprinkling of dust that seemed ever present in his hair. \n\nThe King and Queen graciously waited as the sculptor bowed and then asked \"Your majesties, what can I do for you?\" The Queen leaned forward in her throne and her voice rang out in the court \"We have heard, o Master Sculptor, of your skills from people far and wide across the Kingdom. We dream of having you put your skills to use to build beautiful statues that will represent Lord Jagannath, Subhadra, and Balabhadra for our people to worship.\"\n\nThe sculptor was silent. As his silence extended, ministers of the court began to feel restless. \"Speak up! How can you be silent when the Queen graces you so!\" But still, the sculptor was silent. \n\nThe King and Queen sat patiently in their thrones as they waited for the sculptor to respond. Perhaps the enormity of the task was too much. Perhaps, the sculptor was thinking of what he should ask for in return. Or even more, perhaps, the sculptor was awed and honored by the request. \n\nAt last, as the shadows from the late afternoon sun began to stretch across the floors of the hall, the sculptor shifted his weight, and opened his mouth to speak. \"Your majesties, you grace me with such a request, I cannot help but oblige. It is an honor.\" At this, the Queen sat as straight as a rod, listening for the words that would come next. \"But, I can do this on one condition only. I will work in a closed hall, where none may enter - regardless of whether they can hear me working or otherwise. None may enter until I open the doors from within and proclaim to all that the statues are completed.\"\n\nThe ministers gasped - what a strange request from this man. Was he a fool? What if he just slept and ate and didn't do any work? How could the King and Queen trust that he would do the work he was promising to do? The Queen looked on thoughtfully. She glanced at the King, and it seemed to her that he agreed on this condition without reservation. She looked at the sculptor and then nodded her assent. \"We decree that you shall build these statues in a hall set aside, into which no one shall enter until your work is complete and you proclaim that to us after opening the doors of the hall from within.\"",

In supervised learning, a machine learning algorithm takes a set of training instances (of which the label is known) and seeks to build a model that generates a desired prediction for an unseen instance. To enable the model construction, all instances are represented as a vector of features (i.e., inherent characteristics of the data) that contain information that is potentially useful to distinguish cyberbullying from non-cyberbullying content.\nWe experimentally tested whether cyberbullying events can be recognised automatically by lexical markers in a post. To this end, all posts were represented by a number of information sources (or features) including lexical features like bags-of-words, sentiment lexicon features and topic model features, which are described in more detail below. Prior to feature extraction, some data cleaning steps were executed, such as the replacement of hyperlinks and @-replies, removal of superfluous white spaces, and the replacement of abbreviations by their full form (based on an existing mapping dictionary ). Additionally, tokenisation was applied before INLINEFORM0 -gram extraction and sentiment lexicon matching, and stemming was applied prior to extracting topic model features.\nAfter pre-processing of the corpus, the following feature types were extracted:\nWord INLINEFORM0 -gram bag-of-words: binary features indicating the presence of word unigrams, bigrams and trigrams.\nCharacter INLINEFORM0 -gram bag-of-words: binary features indicating the presence of character bigrams, trigrams and fourgrams (without crossing word boundaries). Character INLINEFORM1 -grams provide some abstraction from the word level and provide robustness to the spelling variation that characterises social media data.\nTerm lists: one binary feature derived for each one out of six lists, indicating the presence of an item from the list in a post: proper names, `allness' indicators (e.g. always, everybody), diminishers (e.g. slightly, relatively), intensifiers (e.g. absolutely, amazingly), negation words and aggressive language and profanity words. Person alternation is a binary feature indicating whether the combination of a first and second person pronoun occurs in order to capture interpersonal intent.\nSubjectivity lexicon features: positive and negative opinion word ratios, as well as the overall post polarity were calculated using existing sentiment lexicons. For Dutch, we made use of the Duoman BIBREF61 and Pattern BIBREF62 lexicons. For English, we included the Hu and Liu opinion lexicon BIBREF63 , the MPQA lexicon BIBREF64 , General Inquirer Sentiment Lexicon BIBREF65 , AFINN BIBREF66 , and MSOL BIBREF67 . For both languages, we included the relative frequency of all 68 psychometric categories in the Linguistic Inquiry and Word Count (LIWC) dictionary for English BIBREF68 and Dutch BIBREF69 .\nTopic model features: by making use of the Gensim topic modelling library BIBREF70 , several LDA BIBREF71 and LSI BIBREF72 topic models with varying granularity ( INLINEFORM0 = 20, 50, 100 and 200) were trained on data corresponding to each fine-grained category of a cyberbullying event (e.g. threats, defamations, insults, defenses). The topic models were based on a background corpus (EN: INLINEFORM1 tokens, NL: INLINEFORM2 tokens) scraped with the BootCAT BIBREF73 web-corpus toolkit. BootCaT collects ASKfm user profiles using lists of manually determined seed words that are characteristic of the cyberbullying categories.\nWhen applied to the training data, this resulted in INLINEFORM0 and INLINEFORM1 features for English and Dutch, respectively.\nPrior to feature extraction, some data cleaning steps were executed, such as the replacement of hyperlinks and @-replies, removal of superfluous white spaces, and the replacement of abbreviations by their full form.",

Among these inherently interpretable models, we wanted to create a model that provides explanations through examples that are known as powerful explanations. That's why we created a prototype-based explanation model, as shown in Section 2 Explanation Methods for DNN.\n\nIn this process, since prototype-based DNNs are mostly made based on the method of [7], there is a problem that similar latent representations do not share a similar appearance. We developed a model to solve these common problems and expand prototype-based explanations. Therefore, as shown in the second paragraph of Explanation Methods for DNN in Section 2, we compared with [7], the paper used as the basis for prototype-based DNN, as a baseline.\n\nTherefore, comparison with the method used as the baseline was carried out in section 4.1, and comparison with methods corresponding to the post-hoc explanation was not carried out. After comparison with the prior work, it was shown that the additional explanations obtained with our method aided the understanding of the judgment of the model in section 5.",
        "evidence": "Explanation Methods for DNN While there are diverse suites of methods to explain DNN, it can be categorized based on the access of the model's internal information and how they provide explanations. The model-agnostic method is to approximate the relationships between input data and output decision while treating the model as a black-box. There are methods to create a local explanation by selecting features that play an essential role in making decisions and methods providing an interpretable model through a global approximate. On the other hand, in knowing the internal information of the model, the model-transparent method provides explanations by saliency map using gradient in classifier, class activation map using global average pooling, and feature map based on attention. The third method provides explanations by examples capturing relationship between test input and the model's decision.\nConsidering that examples are based on training data or learned prototype data, our work is closely aligned with these prototype-based classification models. The example-based method shows its efficacy to explain complex concepts in psychology and education domains, and is also accepted by the general public as the most preferred explanation method to explain.\nThe following three prototype-based classification methods are similar to our method in that they use the distance between the encoded input and prototypes for classification and explanation. learn and visualize the prototypes for the entire data through autoencoder.  go further from here, characterizing training image patches as class-specific prototypes for partial explanations, while feature a hierarchical demonstration of prototypes through related groups for non-flat explanations. As most of prototype-based explanation methods are based on, we use it as a baseline model. Our framework goes further from these methods, expands prototypes from vectors to distribution in latent space and constructs explanation space for diverse explanations with reliability. In addition to prototype-based methods, there are several methods that use the distance in latent space to understand the internal behavior of a model or to provide explanation using VAE or GAN.\nThe largest body of research on estimating uncertainty in deep learning is Bayesian neural networks.\nTo obtain predictive uncertainty, Bayesian neural networks use prior distributions on model parameters and infer the posterior distribution. Although exact inference in Bayesian methods is intractable, a range of approximate techniques has been proposed, such as variational inference and stochastic gradient hamiltonian monte carlo (SG-HMC). However, in practice, these Bayesian methods are outperformed by Deep Ensembles. This non-bayesian technique uses multiple neural networks trained from different initializations and averages their predictions as the model output. It is simple and effective but requires high computational costs at training and test time. Another non-bayesian technique is based on evidential deep learning, which we use to estimate uncertainty. These methods use a single deterministic neural network and apply prior distributions on model predictions, not model parameters.\nAs most of prototype-based explanation methods are based on Li et al. (2018), we use it as a baseline model.",

        "question": "Why did the authors decide to hire annotators and educate them on the Extended Named Entities (ENE) tag set?",
        "answer": "Because none of the works above have considered the multi-lingual nature of many Wikipedia articles and they want to annotate each article with up to 6 different ENE classes, and exploit the Wikipedia language links in the annotated articles to create a multi-lingual Wikipedia classification dataset.",
        "evidence": "Major progress has been made in different tasks in Natural Language Processing, yet our models are still not able to describe why they make their decisions when summarizing an article, translating a sentence, or answering a question. Lack of meta information (e.g. general world knowledge regarding the task) is one important obstacle in the construction of language understanding models capable of reasoning about their considerations when making decisions (predictions).\nWikipedia is a great resource of world knowledge for human beings, but lacks the proper structure to be useful for the models. To address this issue and make a more structured knowledge-base, we are trying to structure Wikipedia. The final goal is to have, for each Wikipedia article, known entities and sets of attributes, with each attribute linking to other entities wherever possible. The initial step towards this goal is to classify the entities into predefined categories and verify the results using human annotators.\nThroughout the past years, many have tried classifying Wikipedia articles into different category sets the majority of which range between 3 to 15 class types BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4. Although useful, such categorization type sets are not much helpful when the classified articles are being used as the training data for Question-Answering systems, since the extracted knowledge-base does not provide detailed enough information to the model.\nOn the other hand, much larger categorization type sets such as Cyc-Taxonomy BIBREF5, Yago-Taxonomy BIBREF6, or Wikipedia's own taxonomy of categories BIBREF7 are not suitable for our task since the tags are not verifiable for annotators. In addition, taxonomies are not designed in a tree format, so some categories might have multiple super-categories and this would make the verification process much harder for the cases that the article is about multiple different topics.\nConsidering the mentioned problem requirements, we believe Extended Named Entities Hierarchy BIBREF8, containing 200 fine-grained categories tailored for Wikipedia articles, is the best fitting tag set.\nHigashinaka et al. higashinaka2012 were the first to use this extended tag set as the categorization output of the dumped Wikipedia pages while using a hand-extracted feature set for converting the pages into their model input vectors. Following their work, Suzuki et al. suzuki2016 modelled the links between different Wikipedia pages as an augmentation to the extracted input features to the classifier. They also proposed a more complex model for learning the mapping between the converted articles and the labels.\nAlthough providing useful insights, none of the works above have considered the multi-lingual nature of many Wikipedia articles. Hence, we decided to hire annotators and educate them on the Extended Named Entities (ENE) tag set to annotate each article with up to 6 different ENE classes, and exploit the Wikipedia language links in the annotated articles to create our multi-lingual Wikipedia classification dataset. Section 2 details our dataset creation process.\nWe then used the two models mentioned above, which are to the best of our knowledge the only works close enough to our task in hand, to benchmark our dataset. Section 3 provides more details about our feature selection method and the models. Section 4 presents our experimental setup and the classification results.\nAlthough providing useful insights, none of the works above have considered the multi-lingual nature of many Wikipedia articles.

        "answer": "EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.",
        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nEqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.",

        "evidence": "Automated, or robotic, journalism aims at news generation from structured data sources, either as the final product or as a draft for subsequent post-editing. At present, automated journalism typically focuses on domains such as sports, finance and similar statistics-based reporting, where there is a commercial product potential due to the high volume of news, combined with the expectation of a relatively straightforward task.\nNews generation systems—especially those deployed in practice—tend to be based on intricate template filling, aiming to give the users the full control of the generated facts, while maintaining a reasonable variability of the resulting text. This comes at the price of having to develop the templates and specify their control logic, neither of which are tasks naturally fitting journalists' work. Further, this development needs to be repeated for every domain, as the templates are not easily transferred across domains. Examples of the template-based news generation systems for Finnish are Voitto by the Finnish Public Service Broadcasting Company (YLE) used for sports news generation, as well as Vaalibotti BIBREF0, a hybrid machine learning and template-based system used for election news.\nBIBREF1 suggested a neural template generation, which jointly models latent templates and text generation. Such a system increases interpretability and controllability of the generation, however, recent sequence-to-sequence systems represent the state-of-the-art in data-to-text generation. BIBREF2\nIn this paper, we report on the development of a news generation system for the Finnish ice hockey news domain, based on sequence-to-sequence methods. In order to train such a system, we compile a corpus of news based on over 2000 game reports from the Finnish News Agency STT. While developing this corpus into a form suitable for training of end-to-end systems naturally requires manual effort, we argue that compiling and refining a set of text examples is a more natural way for journalists to interact with the system, in order for them to codify their knowledge and to adapt it for new domains.\nOur aim is to generate reports that give an overview of a game based on information inferrable from the statistics. Such reports can be used either as a basis for further post-editing by a journalist imprinting own insights and background information, or even used directly as a news stream labelled as machine-generated.\nIn the following, we will introduce the news dataset and the process of its creation, introduce an end-to-end model for news generation, and evaluate its output respective to the abovementioned objectives.\nIn order to train such a system, we compile a corpus of news based on over 2000 game reports from the Finnish News Agency STT.",

        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nWe build a reusable sentiment analysis model that does not utilize any lexicons.",

In our main experiments, we set: the cost of taking a CUR, GOAL, SUB, or DO action to be 0.01 (we will consider other settings subsequently), the cost of calling DONE to terminate the main goal (i.e. task error) equal the (unweighted) length of the shortest-path from the agent's location to the goal, and the goal stack's size (L) to be 2. We compare our RL-learned interaction policy with a rule-based baseline that first takes the GOAL action and then randomly selects actions.\nIn each episode, we enforce that the rule-based policy can take at most X a + y actions of type a, where y ∼ Bernoulli(X a − X a ) and X a is a constant. We tune each X a on the validation sets so that the rule-based policy has the same average count of each action as the RL-learned policy. To prevent early termination, we enforce that the rule-based policy cannot take more DONE actions than SUB actions unless when its SUB action's budget is exhausted. We also construct a skyline where the interaction policy is also learned by RL but with an operation policy that executes subgoals perfectly. As discussed in §5, we are primarily interested in goal-finding success rate and will refer to this metric briefly as success rate.\nMain Results (Table). To inspect the potential benefits of asking for additional information, we compute how much the operation policy π improves when it is supplied with dense information about the current and/or goal states. As seen, success rate of the operation policy is lifted dramatically when both the current-state and goal descriptions are dense (∼2× increase on UNSEENSTR, ∼5× on UNSEENOBJ, and ∼3× on UNSEENENV). We find that dense information about the current state is more helpful on UNSEENSTR, while dense information about the goal is more valuable on UNSEENOBJ and UNSEENENV. This is reasonable because on UNSEENSTR, the agent has been trained to find similar goals. In contrast, the initial goal descriptions in UNSEENOBJ and UNSEE-NENV are completely new to the agent, thus gathering more information about them is necessary.\nAided by our RL-learned interaction policy, the agent observes a substantial ∼2× increase in success rate on UNSEENSTR, ∼5× on UNSEENOBJ, and ∼7× on UNSEENENV, compared to when performing tasks using only the operation policy. In unseen environments, with its capability of requesting subgoals, the agent impressively doubles the success rate of the operation policy that has access to dense descriptions.

This is due to the ability to request subgoals.\nOn UNSEENSTR and UNSEENOBJ, the RL-learned policy has not closed the gap with the operation policy that performs tasks with dense descriptions. Our investigation finds that limited information often causes the policy to not request information about the current state (i.e. taking CUR) and terminate prematurely or go to a wrong place. Encoding uncertainty in the current-state description (e.g.,;) is a plausible future direction for tackling this issue. Finally, results obtained by replacing the learned operation policy with one that behaves optimally on subgoals shows that further improving performance of the operation policy on shortdistance goals would effectively enhance the agent's performance on long-distance goals.\nBehavior of the RL-Learned Interaction Policy. Figure characterizes behaviors of the RLlearned interaction policy in three evaluation conditions. We expect that tasks in UNSEENSTR are the easiest and those in UNSEENENV are the hardest. As the difficulty of the evaluation condition increases, the interaction policy issues more CUR, SUB, and DO actions. The average number of GOAL actions does not vary, showing that the interaction policy has correctly learned that making more than one goal-clarifying request is unnecessary. Figure illustrates the distribution of each action along the length of an episode in the validation UNSEENENV dataset. The GOAL action, if taken, is always taken only once and immediately in the first step. The number of CUR actions gradually decreases over time. The agent makes most SUB requests in the middle of an episode, after its has attempted but failed to accomplish the main goals. We observe similar patterns on the other two validation sets.\nEffects of Varying Action Cost. As mentioned, we assign the same cost to each CUR, GOAL, SUB, or DO action. Figure demonstrates the effects of changing this cost on the success rate of the agent. Setting the cost equal to 0.5 makes it too costly to take any action, inducing a policy that always calls DONE in the first step and thus fails on all tasks. Overall, the success rate of the agent rises as we reduce the action cost. The increase in success rate is most visible in UNSEENENV and least visible in UNSEENSTR. Figure provides more insights. As the action cost decreases, we observe a growth in the number of SUB and DO actions taken by the interaction policy. Meanwhile, the numbers of CUR and GOAL actions are mostly static. Since requesting subgoals is more helpful in unseen environments than in seen environments, the increase in the number of SUB actions leads the more visible boost in success rate on UNSEENENV tasks.\nPerforming Tasks with Deeper Goal Stacks. In Table, we test the functionality of our framework with a stack size 3, allowing the agent to request subgoals of subgoals. As expected, success rate on UNSEENENV is boosted significantly (+11.9% compared to using a stack of size 2). Success rate on UNSEENOBJ is largely unchanged; we find that the agent makes more SUB requests (averagely 4.5 requests per episode compared to 1.0 request made when the stack size is 2), but doing focus on learning a teaching policy in addition to an advice-requesting policy. An important assumption in these papers is that the teacher must share a common action space with the learner. More recent frameworks relax this assumption by allowing the teacher to specify high-level subgoals instead of low-level actions. HARI can be viewed as a strict extension of these frameworks. It allows the human to specify not only subgoals, but also any additional information about the current state and the goal that agent can interpret. Moreover, HARI equips the agent with multiple communication intentions and teaches it to select the most useful intention to convey in a given situation. Another line of work employs standard RL communication protocol, where the human can only transfer knowledge through numerical scores or categorical feedback. propose a framework where the human advises the agent using a domain-specific language, specifying rules that can be incorporated into the agent's model. In contrast, HARI operates with a black-box agent model. extract features from various types of language feedback to construct a reward function for reinforcement learning. We instead focus on deployment-time communication and directly incorporate the human feedback as input to agent's operation policy.\nTask-Oriented Dialog and Generating Natural Language Questions. HARI models a taskoriented dialog problem. Many variants of this problem requires the agent to compose specific questions. The dominant approach in these problems is to mimic pre-collected human utterances. As discussed previously, naively mirroring human external behavior cannot enable agents to understand the limits of their knowledge. We teach the agent to understand its intrinsic needs through interaction with the human and the environment rather than through imitation of human behaviors. Another related line of work concerns generating natural language explanations of model decisions.\nIn summary, this paper presents a general POMDP framework for modeling human-agent communication. While we demonstrate this framework on a simplified navigation problem, our framework can theoretically capture richer types of human-agent communication. Hence, an important empirical question is how well our formulation generalizes to richer environments with more complex interactions and state spaces. Enhancing the sample efficiency of the learning policy by exploiting the hierarchical policy structure is an exciting future direction. Furthermore, techniques for generating faithful explanations can be applied to enhance the specificity of the generated questions.\nCompared to a policy that calls GOAL at the beginning and calls CUR at every step (which is equivalent to the dense-ds -and-dg baseline), our policy achieves higher success rate on UNSEENENV while making two times fewer requests. This is due to the ability to request subgoals.",

We thus reinterpret the skip-gram as a parameterization of a certain supervised naive Bayes topic model (Table TABREF2 , top-right). In this topic model, input words INLINEFORM2 are fully observed “cluster assignments,” and the words in INLINEFORM3 's contexts are a “document.” The skip-gram differs from this supervised topic model only in the parameterization of the “topics” via word vectors which encode the distributions with a log-bilinear model.

        "evidence": "Classical QA systems face two main challenges related to question analysis and answer extraction. Several QA approaches were proposed in the literature for the open domain BIBREF16 , BIBREF17 and the medical domain BIBREF18 , BIBREF19 , BIBREF20 . A variety of methods were developed for question analysis, focus (topic) recognition and question type identification BIBREF21 , BIBREF22 , BIBREF23 , BIBREF24 . Similarly, many different approaches tackled document or passage retrieval and answer selection and (re)ranking BIBREF25 , BIBREF26 , BIBREF27 .\nAn alternative approach consists in finding similar questions or FAQs that are already answered BIBREF28 , BIBREF29 . One of the earliest question answering systems based on finding similar questions and re-using the existing answers was FAQ FINDER BIBREF30 . Another system that complements the existing Q&A services of NetWellness is SimQ BIBREF2 , which allows retrieval of similar web-based consumer health questions. SimQ uses syntactic and semantic features to compute similarity between questions, and UMLS BIBREF31 as a standardized semantic knowledge source. The system achieves 72.2% precision, 78.0% recall and 75.0% F-score on NetWellness questions. However, the method was evaluated only on one question similarity dataset, and the retrieved answers were not evaluated.\nThe aim of the medical task at TREC 2017 LiveQA was to develop techniques for answering complex questions such as consumer health questions, as well as to identify relevant answer sources that can comply with the sensitivity of medical information retrieval.\nThe CMU-OAQA system BIBREF32 achieved the best performance of 0.637 average score on the medical task by using an attentional encoder-decoder model for paraphrase identification and answer ranking. The Quora question-similarity dataset was used for training. The PRNA system BIBREF33 achieved the second best performance in the medical task with 0.49 average score using Wikipedia as the first answer source and Yahoo and Google searches as secondary answer sources. Each medical question was decomposed into several subquestions. To extract the answer from the selected text passage, a bi-directional attention model trained on the SQUAD dataset was used.\nDeep neural network models have been pushing the limits of performance achieved in QA related tasks using large training datasets. The results obtained by CMU-OAQA and PRNA showed that large open-domain datasets were beneficial for the medical domain. However, the best system (CMU-OAQA) relying on the same training data obtained a score of 1.139 on the LiveQA open-domain task.\nWhile this gap in performance can be explained in part by the discrepancies between the medical test questions and the open-domain questions, it also highlights the need for larger medical datasets to support deep learning approaches in dealing with the linguistic complexity of consumer health questions and the challenge of finding correct and complete answers.\nAnother technique was used by ECNU-ICA team BIBREF34 based on learning question similarity via two long short-term memory (LSTM) networks applied to obtain the semantic representations of the questions. To construct a collection of similar question pairs, they searched community question answering sites such as Yahoo! and Answers.com. In contrast, the ECNU-ICA system achieved the best performance of 1.895 in the open-domain task but an average score of only 0.402 in the medical task. As the ECNU-ICA approach also relied on a neural network for question matching, this result shows that training attention-based decoder-encoder networks on the Quora dataset generalized better to the medical domain than training LSTMs on similar questions from Yahoo! and Answers.com.\nThe CMU-LiveMedQA team BIBREF20 designed a specific system for the medical task. Using only the provided training datasets and the assumption that each question contains only one focus, the CMU-LiveMedQA system obtained an average score of 0.353. They used a convolutional neural network (CNN) model to classify a question into a restricted set of 10 question types and crawled \"relevant\" online web pages to find the answers. However, the results were lower than those achieved by the systems relying on finding similar answered questions. These results support the relevance of similar question matching for the end-to-end QA task as a new way of approaching QA instead of the classical QA approaches based on Question Analysis and Answer Retrieval.\nThe aim of the medical task at TREC 2017 LiveQA was to develop techniques for answering complex questions such as consumer health questions, as well as to identify relevant answer sources that can comply with the sensitivity of medical information retrieval.",

        "evidence": "Ethical considerations are established as essential part in planning mental health research and most research projects undergo approval by an ethics committee. On the contrary, the computational linguistics community has started only recently to consider ethical questions BIBREF72 , BIBREF73 . Likely, this is because computational linguistics was traditionally concerned with publicly available, impersonal texts such as newspapers or texts published with some temporal distance, which left a distance between the text and author. Conversely, recent social media research often deals with highly personal information of living individuals, who can be directly affected by the outcomes BIBREF72 .\n BIBREF72 discuss issues that can arise when constructing datasets from social media and conducting analyses or developing predictive models based on these data, which we review here in relation to our project: Demographic bias in sampling the data can lead to exclusion of minority groups, resulting in overgeneralisation of models based on these data. As discussed in the introduction, personal recovery research suffers from a bias towards English-speaking Western individuals of white ethnicity. By studying multilingual accounts of ethnically diverse populations we explicitly address the demographic bias of previous research. Topic overexposure is tricky to address, where certain groups are perceived as abnormal when research repeatedly finds that their language is different or more difficult to process. Unlike previous research BIBREF45 , BIBREF47 , BIBREF46 our goal is not to reveal particularities in the language of individuals affected by mental health problems. Instead, we will compare accounts of individuals with BD from different settings (structured interviews versus informal online discourse) and of different backgrounds. While the latter bears the risk to overexpose certain minority groups, we will pay special attention to this in the dissemination of our results.\nLastly, most research, even when conducted with the best intentions, suffers from the dual-use problem BIBREF74 , in that it can be misused or have consequences that affect people's life negatively. For this reason, we refrain from publishing mental health classification methods, which could be used, for example, by health insurance companies for the risk assessment of applicants based on their social media profiles.\nIf and how informed consent needs to be obtained for research on social media data is a debated issue BIBREF75 , BIBREF76 , BIBREF77 , mainly because it is not straightforward to determine if posts are made in a public or private context. From a legal point of view, the privacy policies of Twitter and Reddit, explicitly allow analysis of the user contents by third party, but it is unclear to what extent users are aware of this when posting to these platforms BIBREF78 . However, in practice it is often infeasible to seek retrospective consent from hundreds or thousands of social media users. According to current ethical guidelines for social media research BIBREF79 , BIBREF80 and practice in comparable research projects BIBREF81 , BIBREF78 , it is regarded as acceptable to waive explicit consent if the anonymity of the users is preserved. Therefore, we will not ask the account holders of Twitter and Reddit posts included in our datasets for their consent.\n BIBREF79 formulate guidelines for ethical social media health research that pertain especially to data collection and sharing. In line with these, we will only share anonymised and paraphrased excerpts from the texts, as it is often possible to recover a user name via a web search for the verbatim text of a post. However, we will make the original texts available as datasets to subsequent research under a data usage agreement. Since the (automatic) annotation of demographic variables in parts of our dataset constitutes especially sensitive information on minority status in conjunction with mental health, we will only share these annotations with researchers that demonstrate a genuine need for them, i.e. to verify our results or to investigate certain research questions.\nAnother important question is in which situations of encountering content indicative of a risk of self-harm or harm to others it would be appropriate or even required by duty of care for the research team to pass on information to authorities. Surprisingly, we could only find two mentions of this issue in social media research BIBREF81 , BIBREF82 . Acknowledging that suicidal ideation fluctuates BIBREF83 , we accord with the ethical review board's requirement in BIBREF81 to only analyse content posted at least three months ago. If the research team, which includes clinical psychologists, still perceives users at risk we will make use of the reporting facilities of Twitter and Reddit.\nAs a central component we consider the involvement of individuals with lived experience in our project, an aspect which is missing in the discussion of ethical social media health research so far. The proposal has been presented to an advisory board of individuals with a BD diagnosis and was received positively. The advisory board will be consulted at several stages of the project to inform the research design, analysis, and publication of results. We believe that board members can help to address several of the raised ethical problems, e.g., shaping the research questions to avoid feeding into existing biases or overexposing certain groups and highlighting potentially harmful interpretations and uses of our results.\nBy studying multilingual accounts of ethnically diverse populations we explicitly address the demographic bias of previous research.",

To this end, we ranked the words appearing in positive sentences according to their information gain for this task. The top of the list comprises the following: that, sexual, people, movement, religious, issues, rights.\nThe Wikipedia list of controversial issues specifies categories for the listed concepts, like Politics and economics, Religion, History, and Sexuality (some concepts are associated with two or more categories). While some top-ranked words - that, people, issues - do seem to directly indicate controversiality BIBREF12, BIBREF13, others seem to have more to do with the category they belong to. Although these categories may indeed indicate controversiality, we consider this as an indirect or implicit indication, since it is more related to the controversial theme than to controversiality per-se.\nTo control for this effect, we performed a second experiment where we set the concepts from one category as the test set, and used the others for training (concepts associated with the excluded category are left out, regardless of whether they are also associated with one of the training categories). We did this for 5 categories: History, Politics and economics, Religion, Science, and Sexuality. This way, thematic relatedness observed in the training set should have little or no effect on correctly estimating the level of controversy associated of concepts in the test set, and may even “mislead” the estimator. We note that previous work on controversiality does not seem to address this issue, probably because the meta-data used is less sensitive to it.\nIn a preliminary task, we looked for words which may designate sentences associated with controversial concepts. To this end, we ranked the words appearing in positive sentences according to their information gain for this task.",

        "answer": "The Citizens United case is ultimately one pertaining to freedom of speech—while undeniable to US citizens, the protection of free speech was previously denied to unions and corporations. Now, they can express support or criticism of political candidates. This should be good news for both dominant political parties, as liberals tending to support unions and conservatives tending to laud free enterprise both have great voice in the election process. Concern, however, has been raised that companies now have too loud a voice.\nBut, who makes up companies? Individual humans, who are free to join and leave those companies at will. Why would a group of humans be devoid of any rights to which the individuals of the group are entitled? The constitutional right to free speech, it follows, applies to groups of individuals – which companies are – and those groups should be able to leverage their earned dollars to further promote their own well-being. And the ruling has legal precedent: dating back to 1868, US corporations have enjoyed equal protection under the 14th amendment and protection against search and seizure without warrant (Totenberg, N.)\nBut the decision cannot be analyzed solely through legal theory. What have the actual impacts been since the ruling? Rather than observing unlimited spending from corporations as feared, the last ten years have reemphasized the importance of low-level donors; instead of focusing power on just one party or candidate that certain corporations back, political parties have taken turns assuming power; corporate donations remain under 10% of total political spending at the federal level. Furthermore, it seems that wealthy individuals, rather than any specific union or corporation, have been making oversized donations that dominant the budgets of super-PACs. It follows that any concerns around voices dominating the political conversation are indeed individuals, not unions or corporations as fear.\nCitizens United allows companies to further act in their best interests and raise issues pertaining to the business.

For any program f that might determine whether programs halt, a \"pathological\" program g, called with some input, can pass its own source and its input to f and then specifically do the opposite of what f predicts g will do. No f can exist that handles this case. A key part of the proof is a mathematical definition of a computer and program, which is known as a Turing machine; the halting problem is undecidable over Turing machines. It is one of the first cases of decision problems proven to be unsolvable.

Joseph Weizenbaum created it at the MIT in 1966 and it is well known for acting like a psychotherapist and it had only to reflect back onto patient's statements. ELIZA was created to tackle five \"fundamental technical problems\": the identification of critical words, the discovery of a minimal context, the choice of appropriate transformations, the generation of appropriate responses to the transformation or in the absence of critical words, and the provision of an ending capacity for ELIZA scripts.\nRight after ELIZA came PARRY, developed by Kenneth Colby, who is psychiatrist at Stanford University in the early 1970s. The program was written using the MLISP language (meta-lisp) on the WAITS operating system running on a DEC PDP-10 and the code is non-portable. Parts of it were written in PDP-10 assembly code and others in MLISP. There may be other parts that require other language translators.

        "evidence": "Despite the American public's increasing acceptance of LGBTQ people and recent legal successes, LGBTQ individuals frequently remain the targets of hate and violence BIBREF0, BIBREF1, BIBREF2. At the core of this issue is dehumanization, “the act of perceiving or treating people as less than human” BIBREF3, a process that heavily contributes to extreme intergroup bias BIBREF4. Language is central to studying this phenomenon; like other forms of bias BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, dehumanizing attitudes are expressed through subtle linguistic manipulations, even in carefully-edited texts. It is crucial to understand the use of such linguistic signals in mainstream media, as the media's representation of marginalized social groups has far-reaching implications for social acceptance, policy, and safety.\nWhile small-scale studies of dehumanization and media representation of marginalized communities provide valuable insights (e.g. BIBREF10), there exist no known large-scale analyses, likely due to difficulties in quantifying such a subjective and multidimensional psychological process. However, the ability to do large-scale analysis is crucial for understanding how dehumanizing attitudes have evolved over long periods of time. Furthermore, by being able to account for a greater amount of media discourse at once, large-scale techniques can provide a more complete view of the media environment to which the public is exposed.\nLinguistics and computer science offer valuable methods and insights on which such large-scale techniques might be developed for the study of dehumanization. By leveraging more information about the contexts in which marginalized groups are discussed, computational linguistic methods not only enable large-scale study of a complex psychological phenomenon, but can even reveal linguistic variations and changes that are not easily identifiable through qualitative analysis alone.\nIn this work, we develop a computational linguistic framework for analyzing dehumanizing language, with a focus on lexical signals of dehumanization. Social psychologists have identified numerous components of dehumanization, such as negative evaluations of a target group, denial of agency, moral disgust, and likening members of a target group to non-human entities such as vermin. Drawing upon this rich body of literature, we first identify clear linguistic analogs for these components and propose several computational techniques to measure these linguistic correlates. We then apply this general framework to explore changing representations of LGBTQ groups in the New York Times over the span of three decades. We additionally use this lens of dehumanization to investigate differences in social meaning between the denotationally-similar labels gay and homosexual.\nThis paper aims to bridge the gaps between computational modeling, sociolinguistics, and dehumanization research with implications for several disciplines. In addition to enabling large-scale studies of dehumanizing language and media representation of marginalized social groups, these techniques can be built into systems that seek to capture both conscious and unconscious biases in text. Furthermore, this work has implications for improving machines' abilities to automatically detect hate speech and abusive language online, which are typically underpinned by dehumanizing language.

For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. Interest in using hydrogen for on-board storage of energy in zero-emissions vehicles is motivating the development of new methods of storage, more adapted to this new application.

        "evidence": "In order to provide directions for future work, we analyze the errors made by the classifier trained on the extended features on the four prediction tasks.\nErrors on Intention (I) prediction: The lack of background is a major problem when identifying trolling comments. For example, “your comments fit well in Stormfront” seems inoffensive on the surface. However, people who know that Stormfront is a white supremacist website will realize that the author of this comment had an annoying or malicious intention. But our system had no knowledge about it and simply predicted it as non-trolling. These kind of errors reduces recall on the prediction of trolling comments. A solution would be to include additional knowledge from anthologies along with a sentiment or polarity. One could modify NELL BIBREF12 to broaden the understanding of entities in the comments.\nNon-cursing aggressions and insults This is a challenging problem, since the majority of abusive and insulting comments rely on profanity and swearing. The problem arises with subtler aggressions and insults that are equally or even more annoying, such as “Troll? How cute.” and “settle down drama queen”. The classifier has a more difficult task of determining that these are indeed aggressions or insults. This error also decreases the recall of trolling intention. A solution would be to exploit all the comments made by the suspected troll in the entire conversation in order to increase the chances of finding curse words or other cues that lead the classifier to correctly classify the comment as trolling.\nAnother source of error is the presence of controversial topic words such as “black”,“feminism”, “killing”, “racism”, “brown”, etc. that are commonly used by trolls. The classifier seems too confident to classify a comment as trolling in the presence of these words, but in many cases they do not. In order to ameliorate this problem, one could create ad-hoc word embeddings by training glove or other type of distributed representation on a large corpus for the specific social media platform in consideration. From these vectors one could expect a better representation of controversial topics and their interactions with other words so they might help to reduce these errors.\nErrors on Disclosure (D) prediction: A major source of error that affects disclosure is the shallow meaning representation obtained from the BOW model even when augmented with the distributional features given by the glove vectors. For example, the suspected troll's comment “how to deal with refugees? How about a bullet to the head” is clearly mean-spirited and is an example of disclosed trolling. However, to reach that conclusion the reader need to infer the meaning of “bullet to the head” and that this action is desirable for a vulnerable group like migrants or refugees. This problem produces low recall for the disclosed prediction task. A solution for this problem may be the use of deeper semantics, where we represent the comments and sentences in their logical form and infer from them the intended meaning.\nErrors on Interpretation (R) prediction: it is a common practice from many users to directly ask the suspected troll if he/she is trolling or not. There are several variations of this question, such as “Are you a troll?” and “not sure if trolling or not”. While the presence of a question like these seems to give us a hint of the responder's interpretation, we cannot be sure of his interpretation without also considering the context. One way to improve interpretation is to exploit the response strategy, but the response strategy in our model is predicted independently of interpretation. So one solution could be similar to the one proposed above for the disclosure task problem: jointly learning classifiers that predict both variables simultaneously. Another possibility is to use the temporal sequence of response comments and make use of older response interpretation as input features for later comments. This could be useful since commenters seem to influence each other as they read through the conversation.\nErrors on Response Strategy (B) prediction: In some cases there is a blurry line between “Frustrate” and “Neutralize”. The key distinction between them is that there exists some criticism in the Frustrate responses towards the suspected troll's comment, while “Neutralizing” comments acknowledge that the suspected troll has trolling intentions, but gives no importance to them. For example, response comments such as “oh, you are a troll” and “you are just a lame troll” are examples of this subtle difference. The first is a case of “neutralize” while the second is indeed criticizing the suspected troll's comment and therefore a “frustrate” response strategy. This kind of error affects both precision and recall for these two classes. A possible solution could be to train a specialized classifier to disambiguate between “frustrate” and “neutralize” only.\nAnother challenging problem is the distinction between the classes “Troll” and “Engage”. This is true when the direct responder is intensely flared up with the suspected comment to the point that his own comment becomes a trolling attempt. A useful indicator for distinguishing these cases are the presence of insults, and to detect them we look for swear words, but as we noted before, there is no guarantee that swear words are used for insulting. This kind of error affects the precision and recall for the “troll” and “engage” classes. A solution to this problem may be the inclusion of longer parts of the conversation. It is typical in a troll-engaged comment scheme to observe longer than usual exchanges between two users, and the comments evolve in very agitated remarks. One may then use this information to disambiguate between the two classes.\nIn order to provide directions for future work, we analyze the errors made by the classifier trained on the extended features on the four prediction tasks.\n\nErrors on Intention (I) prediction: The lack of background is a major problem when identifying trolling comments.\nNon-cursing aggressions and insults This is a challenging problem, since the majority of abusive and insulting comments rely on profanity and swearing. \nAnother source of error is the presence of controversial topic words such as “black”,“feminism”, “killing”, “racism”, “brown”, etc. that are commonly used by trolls.\nErrors on Disclosure (D) prediction: A major source of error that affects disclosure is the shallow meaning representation obtained from the BOW model even when augmented with the distributional features given by the glove vectors.\nErrors on Interpretation (R) prediction: it is a common practice from many users to directly ask the suspected troll if he/she is trolling or not. \nErrors on Response Strategy (B) prediction: In some cases there is a blurry line between “Frustrate” and “Neutralize”. \nAnother challenging problem is the distinction between the classes “Troll” and “Engage”.

These corpora are based on Wikipedia, so more comparable than the others, and have already been used for the evaluation of several QA systems.\nWikiQA BIBREF6 comprises questions selected from the Bing search queries, where user click data give the questions and their corresponding Wikipedia articles. The abstracts of these articles are then extracted to create answer candidates. The assumption is made that if many queries lead to the same article, it must contain the answer context; however, this assumption fails for some occasions, which makes this dataset more challenging. Since the existence of answer contexts is not guaranteed in this task, it is called answer triggering instead of answer selection.\nSelQA BIBREF7 is a product of five annotation tasks through crowdsourcing. It consists of about 8K questions where a half of the questions are paraphrased from the other half, aiming to reduce contextual similarities between questions and answers. Each question is associated with a section in Wikipedia where the answer context is guaranteed, and also with five sections selected from the entire Wikipedia where the selection is made by the Lucene search engine. This second dataset does not assume the existence of the answer context, so can be used for the evaluation of answer triggering.\nSQuAD BIBREF12 presents 107K+ crowdsourced questions on 536 Wikipedia articles, where the answer contexts are guaranteed to exist within the provided paragraph.

        "question": "Their approaches are informed by what?",
        "answer": "Social psychology research on dehumanization.",
        "evidence": "Our lexical semantic analysis involves quantifying linguistic correlates of component psychological processes that contribute to dehumanization. Our approaches are informed by social psychology research on dehumanization, which is briefly summarized here. Prior work has identified numerous related processes that comprise dehumanization BIBREF4. One such component is likening members of the target group to non-human entities, such as machines or animals BIBREF4, BIBREF11, BIBREF12. By perceiving members of a target group to be non-human, they are “outside the boundary in which moral values, rules, and considerations of fairness apply\" BIBREF13, which thus leads to violence and other forms of abuse. Metaphors and imagery relating target groups to vermin are particularly insidious and played a prominent role in the genocide of Jews in Nazi Germany and Tutsis in Rwanda BIBREF14. More recently, the vermin metaphor has been invoked by the media to discuss terrorists and political leaders of majority-Muslim countries after September 11 BIBREF15. According to BIBREF16, the vermin metaphor is particularly powerful because it conceptualizes the target group as “engaged in threatening behavior, but devoid of thought or emotional desire\".\nDisgust underlies the dehumanizing nature of these metaphors and is itself another important element of dehumanization. Disgust contributes to members of target groups being perceived as less-than-human and of negative social value BIBREF17. It is often evoked (both in real life and experimental settings) through likening a target group to animals. BIBREF18 find that priming participants to feel disgust facilitates “moral exclusion of out-groups\". Experiments by BIBREF17 and BIBREF19 similarly find that disgust is a predictor of dehumanizing perceptions of a target group. Both moral disgust towards a particular social group and the invocation of non-human metaphors are facilitated by essentialist beliefs about groups, which BIBREF4 presents as a necessary component of dehumanization. In order to distinguish between human and non-human, dehumanization requires an exaggerated perception of intergroup differences. Essentialist thinking thus contributes to dehumanization by leading to the perception of social groups as categorically distinct, which in turn emphasizes intergroup differences BIBREF4\nAccording to BIBREF4, much of the prior research describes “extremely negative evaluations of others\" as a major component of dehumanization. This is especially pronounced in BIBREF20's account of delegitimization, which involves using negative characteristics to categorize groups that are “excluded from the realm of acceptable norms and values\" BIBREF20. While BIBREF20 defines delegitimization as a distinct process, he considers dehumanization to be one means of delegitimization. BIBREF13 also discusses broader processes of moral exclusion, one of which is dehumanization. A closely related process is psychological distancing, in which one perceives others to be objects or nonexistent BIBREF13. BIBREF21 identifies elements that contribute to the objectification (and thus dehumanization) of women, one of which is denial of subjectivity, or the habitual neglect of one's experiences, emotions, and feelings.\nAnother component of dehumanization is the denial of agency to members of the target group BIBREF4. According to BIBREF16, there are three types of agency: \"the ability to (1) experience emotion and feel pain (affective mental states), (2) act and produce an effect on their environment (behavioral potential), and (3) think and hold beliefs (cognitive mental states) BIBREF16. Dehumanization typically involves the denial of one or more of these types of agency BIBREF16.\nIn Section SECREF4, we introduce computational linguistic methods to quantify several of these components of dehumanization.\nIn Section SECREF1, we briefly discussed multiple elements of dehumanization that have been identified in social psychology literature. Here we introduce and quantify lexical correlates to operationalize four of these components: negative evaluations of a target group, denial of agency, moral disgust, and use of non-human metaphors (particularly vermin).\nOne prominent aspect of dehumanization is extremely negative evaluations of members of a target group BIBREF4. Attribution of negative characteristics to members of a target group in order to exclude that group from “the realm of acceptable norms and values\" is specifically the key component of delegitimization, a process of moral exclusion closely related to dehumanization. We hypothesize that this negative evaluation of a target group can be realized by words and phrases whose connotations have extremely low valence, where the valence of a word refers to the dimension of meaning corresponding to positive/negative (or pleasure/displeasure) BIBREF55, BIBREF56. Thus, we propose several valence lexicon-based approaches to measure this component: paragraph-level valence analysis, Connotation Frames, and word embedding neighbor valence. Each of these techniques has different advantages and disadvantages regarding precision and interpretability.\nAs we mentioned above, one important dimension of affective meaning is valence, which corresponds to an individual's evaluation of an event or concept, ranging from negative/unpleasant to positive/pleasant BIBREF55, BIBREF57. A straightforward lexical approach to quantify negative evaluations of a target group is thus to measure the average valence over all words in corpora containing discussions of the target group. We quantify this by using the valence dimension from the NRC VAD lexicon, which contains real-valued scores ranging from zero to one for valence, arousal and dominance for 20,000 English words, where a score of zero is the lowest valence (most negative emotion) and a score of one is the highest possible valence (most positive emotion) BIBREF56. Words with the highest valence in the NRC VAD Lexicon include love, happy, and happily, while words with the lowest valence include toxic, nightmare, and shit.\nIn our case study, we qualitatively found that paragraphs were the optimal level of context for analysis; full articles often focused on topics unrelated to LGBTQ communities, even if an LGBTQ label was mentioned somewhere in the article, while single sentences did not provide enough discussion to get a sense of how LGBTQ groups are represented by the newspaper. Thus, we calculate paragraph-level scores by taking the average valence score over all words in the paragraph that appear (or whose lemmas appear) in the NRC VAD lexicon.\nWhile paragraph-level valence analysis is quick and simple, it is sometimes too coarse because we aim to understand the sentiment directed towards the target group, not just nearby in the text. For example, suppose the target group is named “B\". A sentence such as “A violently attacked B\" would likely have extremely negative valence, but the writer may not feel negatively towards the victim, “B\".\nWe address this by using BIBREF22's Connotation Frames Lexicon, which contains rich annotations for 900 English verbs (BIBREF22). Among other things, for each verb, the Connotation Frames Lexicon provides scores (ranging from -0.87 to 0.8) for the writer's perspective towards the verb's subject and object. In the example above for the verb attack, the lexicon lists the writer's perspective towards the subject “A\", the attacker, as -0.6 (strongly negative) and the object “B\" as 0.23 (weakly positive).\nWe extract all subject-verb-object tuples containing at least one target group label using the Spacy dependency parser . For each subject and object, we capture the noun and the modifying adjectives, as group labels (such as gay) can often take either nominal or adjectival forms. For each tuple, we use the connotation frame lexicon to determine the writer's perspective either towards the subject if the group label appears in the subject noun phrase, or perspective towards the object if the label appears in the object noun phrase. We then average perspective scores over all tuples.\nWhile a Connotation Frames approach can be more precise than word-counting valence analysis, it limits us to analyzing SVO triples, which excludes a large portion of the available data about the target groups. This reveals a conundrum: broader context can provide valuable insights into the implicit evaluations of a social group, but we also want to directly probe attitudes towards the group itself.\nWe address this tension by training vector space models to represent the data, in which each unique word in a large corpus is represented by a vector (embedding) in high-dimensional space. The geometry of the resulting vector space captures many semantic relations between words. Furthermore, prior work has shown that vector space models trained on corpora from different time periods can capture semantic change BIBREF58, BIBREF59. For example, diachronic word embeddings reveal that the word gay meant “cheerful\" or “dapper\" in the early 20th century, but shifted to its current meaning of sexual orientation by the 1970s. Because word embeddings are created from real-world data, they contain real-world biases. For example, BIBREF37 demonstrated that gender stereotypes are deeply ingrained in these systems. Though problematic for the widespread use of these models in computational systems, these revealed biases indicate that word embeddings can actually be used to identify stereotypes about social groups and understand how they change over time BIBREF24.\nThis technique can similarly be applied to understand how a social group is negatively evaluated within a large text corpus. If the vector corresponding to a social group label is located in the semantic embedding space near negative words or terms with clearly negative evaluations, that group is likely negatively evaluated (and possibly dehumanized) in the text. These vector space models can be used in a diachronic study to capture subtle changes in the connotations of a group label over time, even when the denotational meaning of the label has remained constant. Furthermore, comparing differences in what words are most closely associated with related group labels can reveal meaning variation between these labels, even if they refer to similar populations.\nWe first preprocess the data by lowercasing, removing numbers, and removing punctuation. We then use the word2vec skip-gram model to create word embeddings BIBREF60. The resulting vector spaces have 100 dimensions, and we specify the following additional parameters to the model: context window of size 10, minimum frequency of 5 for a word to be included, 10 negative samples, 10 iterations, and a sampling rate of $10^{-4}$. We then use cosine similarity to determine a group label's nearest neighbors in the vector space. For our diachronic analysis, we first train word2vec on the entire corpus, and then use the resulting vectors to initialize word2vec models for each year of data in order to encourage coherence and stability across years. After training word2vec, we zero-center and normalize all embeddings to alleviate the hubness problem BIBREF61.\nWe then identify vectors for group labels by taking the centroid of all morphological forms of the label, weighted by frequency. For example, the vector representation for the label gay is actually the weighted centroid of the words gay and gays. This enables us to simultaneously account for adjectival, singular nominal, and plural nominal forms for each social group label with a single vector. Finally, we estimate the valence for each group label by identifying its 1000 nearest neighbors via cosine similarity (1000 was chosen arbitrarily), and calculating the average valence of all neighbors that appear in the NRC VAD valence lexicon.\nWe also tried using a group label's vector representation to induce a valence score directly, instead of using nearest neighbors as a proxy, by adapting the regression-based sentiment prediction from BIBREF62 for word embeddings. We found that this approach yielded similar results as analyzing nearest neighbor valence but was difficult to qualitatively interpret. More details for and results from this technique can be found in the Appendix.\nDenial of agency refers to the lack of attributing a target group member with the ability to control their own actions or decisions BIBREF16. Automatically detecting the extent to which a writer attributes cognitive abilities to a target group member is an extraordinarily challenging computational task. Fortunately, the same lexicons used to operationalize negative evaluations provide resources for measuring lexical signals of denial of agency.\nAs in Section SECREF6, we use Connotation Frames to quantify the amount of agency attributed to a target group. We use BIBREF25's extension of Connotation Frames for agency BIBREF25. Following BIBREF25's interpretation, entities with high agency exert a high degree of control over their own decisions and are active decision-makers, while entities with low agency are more passive BIBREF25. This contrast is particularly apparent in example sentences such as X searched for Y and X waited for Y, where the verb searched gives X high agency and waited gives X low agency BIBREF25. Additionally, BIBREF25's released lexicon for agency indicates that the subjects of verbs such as attack and praise are given high agency, while the subjects of doubts, needs, and owes are given low agency BIBREF25.\nThis lexicon considers the agency attributed to subjects of nearly 2000 transitive and intransitive verbs. To use this lexicon to quantify denial of agency in our corpus, we extract all sentences' head verbs and their corresponding subjects, where the subject noun phrase contains a target group label. Unlike BIBREF22's real-valued Connotation Frames lexicon for perspective, the agency lexicon only provides binary labels, so we calculate the fraction of subject-verb pairs where a subject containing a group label was given high agency by its head verb.\nThe NRC VAD lexicon's dominance annotations provide another resource for quantifying dehumanization BIBREF56. As with valence, the NRC VAD lexicon's dominance dimension contains real-valued scores between zero and one for 20,000 English words. However, it is important to note that the dominance lexicon primarily captures power, which is distinct from but closely related to agency. While power refers to one's control over others, agency refers to one's control over their own self. While this lexicon is a proxy, it qualitatively appears to capture signals of denial of agency; the highest dominance words are powerful, leadership, success, and govern, while the lowest dominance words are weak, frail, empty, and penniless. We thus take the same approach as in Section SECREF10 with the same vector space models. However, we now calculate the average dominance score of the 1000 nearest neighbors to each group label vector representation.\nAs in Section SECREF10, we also induced a dominance score directly from a group label's vector representation by adapting the regression-based sentiment prediction from BIBREF62 for word embeddings. More details and results for this technique can be found in the Appendix.\nIn order to operationalize the moral disgust component of dehumanization with lexical techniques, we draw inspiration from Moral Foundations theory, which postulates that there are five dimensions of moral intuitions: care, fairness/proportionality, loyalty/ingroup, authority/respect, and sanctity/purity BIBREF63. The negative end of the sanctity/purity dimension corresponds to moral disgust. While we do not directly incorporate Moral Foundations Theory in our framework for dehumanization, we utilize lexicons created by BIBREF64 corresponding to each moral foundation. The dictionary for moral disgust includes over thirty words and stems, including disgust*, sin, pervert, and obscen* (the asterisks indicate that the dictionary includes all words containing the preceding prefix, such as both obscene and obscenity).\nWe opt for a vector approach instead of counting raw frequencies of moral disgust-related words because words that explicitly invoke moral disgust are very sparse in our news corpus. Furthermore, vectors are capable of capturing associations with the social group label itself, while counts in paragraphs and full news articles would not directly capture such associations. Using the word embeddings from Section SECREF10, we construct a vector to represent the concept of moral disgust, which is the average of the corresponding vectors for all words in the “Moral Disgust\" dictionary, weighted by word frequency. This method of creating a vector from the Moral Foundations dictionary resembles that used by BIBREF65. We can then analyze implicit associations between a social group and moral disgust by calculating the cosine similarity between the group label's vector and the Moral Disgust concept vector, where a higher similarity suggests closer associations between the social group and moral disgust. As previously, each group label's vector is the average of its morphological variants' vectors, weighted by frequency.\nMetaphors comparing humans to vermin have been especially prominent in dehumanizing groups throughout history BIBREF4, BIBREF15. Even if a marginalized social group is not directly equated to vermin in the press, this metaphor may be invoked in more subtle ways, such as through the use of verbs that are also associated with vermin (like scurry as opposed to the more neutral hurry) BIBREF66. While there is some natural language processing work on the complex task of metaphor detection (e.g. BIBREF67, BIBREF67), such systems would not be able to easily quantify such indirect associations.\nWe thus quantify the metaphorical relationship between a social group and vermin by calculating similarities between these concepts in a distributional semantic vector space, as we did with moral disgust in Section SECREF14. We create a Vermin concept vector by calculating the average of the following vermin words' vectors, weighted by frequency: vermin, rodent(s), rat(s) mice, cockroaches, termite(s), bedbug(s), fleas . We do not include the singular mouse or flea because non-vermin senses of those words were more frequent (computer mouse and flea market, respectively), and word2vec does not account for polysemy. We calculate cosine similarity between each social group label and the Vermin concept vector. A large cosine similarity between a label and the Vermin vector suggests that the social group is closely associated with vermin.\nTable TABREF18 provides an overview of the four elements of dehumanization that we study and the lexical techniques used to quantify them.\nOur approaches are informed by social psychology research on dehumanization, which is briefly summarized here.",

        "evidence": "Recent advances in Machine Learning (ML) and, in particular, in Deep Neural Networks (DNN) have allowed the development of highly accurate predictive systems for numerous applications. Among others, health has received significant attention due to the potential of ML-based diagnostic, monitoring and therapeutic systems, which are fast (when compared to traditional diagnostic processes), easily distributed and cheap to implement (many such systems can be executed in mobile devices). Furthermore, these systems can incorporate biometric data to perform non-invasive diagnostics.\nAmong other data types, speech has been proposed as a valuable biomarker for the detection of a myriad of diseases, including: neurological conditions, such as Alzheimer’s BIBREF0, Parkinson’s disease (PD) BIBREF1 and Amyotrophic Lateral Sclerosis BIBREF2; mood disorders, such as depression, anxiety BIBREF3 and bipolar disorder BIBREF4; respiratory diseases, such as obstructive sleep apnea (OSA) BIBREF5. However, temporal and financial constraints, lack of awareness in the medical community, ethical issues and patient-privacy laws make the acquisition of medical data one of the greatest obstacles to the development of health-related speech-based classifiers, particularly for deep learning models. For this reason, most systems rely on knowledge-based (KB) features, carefully designed and selected to model disease symptoms, in combination with simple machine learning models (e.g. Linear classifiers, Support Vector Machines). KB features may not encompass subtler symptoms of the disease, nor be general enough to cover varying levels of severity of the disease. To overcome this limitation, some works have instead focused on speaker representation models, such as Gaussian Supervectors and i-vectors. For instance, Garcia et al. BIBREF1 proposed the use of i-vectors for PD classification and Laaridh et al. BIBREF6 applied the i-vector paradigm to the automatic prediction of several dysarthric speech evaluation metrics like intelligibility, severity, and articulation impairment. The intuition behind the use of these representations is the fact that these algorithms model speaker variability, which should include disease symptoms BIBREF1.\nProposed by Snyder et al., x-vectors are discriminative deep neural network-based speaker embeddings, that have outperformed i-vectors in tasks such as speaker and language recognition BIBREF7, BIBREF8, BIBREF9. Even though it may not be evident that discriminative data representations are suitable for disease detection when trained with general datasets (that do not necessarily include diseased patients), recent works have shown otherwise. X-vectors have been successfully applied to paralinguistic tasks such as emotion recognition BIBREF10, age and gender classification BIBREF11, the detection of obstructive sleep apnea BIBREF12 and as a complement to the detection of Alzheimer's Disease BIBREF0. Following this line of research, in this work we study the hypothesis that speaker characteristics embedded in x-vectors extracted from a single network, trained for speaker identification using general data, contain sufficient information to allow the detection of multiple diseases. Moreover, we aim to assess if this information is kept even when language mismatch is present, as has already been shown to be true for speaker recognition BIBREF8. In particular, we use the x-vector model as a feature extractor, to train Support Vector Machines for the detection of two speech-affecting diseases: Parkinson's disease (PD) and obstructive sleep apnea (OSA).\nPD is the second most common neurodegenerative disorder of mid-to-late life after Alzheimer’s disease BIBREF13, affecting 1% of people over the age of 65. Common symptoms include bradykinesia (slowness or difficulty to perform movements), muscular rigidity, rest tremor, as well as postural and gait impairment. 89% of PD patients develop also speech disorders, typically hypokinetic dysarthria, which translates into symptoms such as reduced loudness, monoloudness, monopitch, hypotonicity, breathy and hoarse voice quality, and imprecise articulation BIBREF14BIBREF15.\nOSA is a sleep-concerned breathing disorder characterized by a complete stop or decrease of the airflow, despite continued or increased inspiratory efforts BIBREF16. This disorder has a prevalence that ranges from 9% to 38% through different populations BIBREF17, with higher incidence in male and elderly groups. OSA causes mood and personality changes, depression, cognitive impairment, excessive daytime sleepiness, thus reducing the patients' quality of life BIBREF18, BIBREF19. It is also associated with diabetes, hypertension and cardiovascular diseases BIBREF16, BIBREF20. Moreover, undiagnosed sleep apnea can have a serious economic impact, having had an estimated cost of $\\$150$ billion in the U.S, in 2015 BIBREF21. Considering the prevalence and serious nature of the two diseases described above, speech-based technology that tests for their existence has the potential to become a key tool for early detection, monitoring and prevention of these conditions BIBREF22.\nThe remainder of this document is organized as follows. Section SECREF2 presents the background concepts on speaker embeddings, and in particular on x-vectors. Section SECREF3 introduces the experimental setup: the corpora, the tasks, the KB features and the speaker embeddings employed. The results are presented and discussed in section SECREF4. Finally, section SECREF5 summarizes the main conclusions and suggests possible directions for future work.\nMoreover, we aim to assess if this information is kept even when language mismatch is present, as has already been shown to be true for speaker recognition.",

For these drums, start by getting all tension rods finger-tight. Bring the snare drum up to tension with a full turn of a drum key of each one, moving in a star pattern around the drum. Use a drumstick to tap around the drum by each tension rod and listen for a consistent sound. \n\nOnce you have the overall sound in the range you’re looking for, test the pitch by tapping around the drum. For the snare’s resonant head, detune it like the batter head. Tune it ‘tabletop tight’: so flat you could confidently rest a drink on it (don’t do this, though). Bring up each tension rod another quarter turn. You want to hear the wires, but not so much that it overwhelms the attack.

        "answer": "Yes.",
        "evidence": "Language model pre-training has proven to be highly effective in learning universal language representations from large-scale unlabeled data. ELMo BIBREF0, GPT BIBREF1 and BERT BIBREF2 have achieved great success in many NLP tasks, such as sentiment classification BIBREF3, natural language inference BIBREF4, and question answering BIBREF5.\nDespite its empirical success, BERT's computational efficiency is a widely recognized issue because of its large number of parameters. For example, the original BERT-Base model has 12 layers and 110 million parameters. Training from scratch typically takes four days on 4 to 16 Cloud TPUs. Even fine-tuning the pre-trained model with task-specific dataset may take several hours to finish one epoch. Thus, reducing computational costs for such models is crucial for their application in practice, where computational resources are limited.\nMotivated by this, we investigate the redundancy issue of learned parameters in large-scale pre-trained models, and propose a new model compression approach, Patient Knowledge Distillation (Patient-KD), to compress original teacher (e.g., BERT) into a lightweight student model without performance sacrifice. In our approach, the teacher model outputs probability logits and predicts labels for the training samples (extendable to additional unannotated samples), and the student model learns from the teacher network to mimic the teacher's prediction.\nDifferent from previous knowledge distillation methods BIBREF6, BIBREF7, BIBREF8, we adopt a patient learning mechanism: instead of learning parameters from only the last layer of the teacher, we encourage the student model to extract knowledge also from previous layers of the teacher network. We call this `Patient Knowledge Distillation'. This patient learner has the advantage of distilling rich information through the deep structure of the teacher network for multi-layer knowledge distillation.\nWe also propose two different strategies for the distillation process: ($i$) PKD-Last: the student learns from the last $k$ layers of the teacher, under the assumption that the top layers of the original network contain the most informative knowledge to teach the student; and ($ii$) PKD-Skip: the student learns from every $k$ layers of the teacher, suggesting that the lower layers of the teacher network also contain important information and should be passed along for incremental distillation.\nWe evaluate the proposed approach on several NLP tasks, including Sentiment Classification, Paraphrase Similarity Matching, Natural Language Inference, and Machine Reading Comprehension. Experiments on seven datasets across these four tasks demonstrate that the proposed Patient-KD approach achieves superior performance and better generalization than standard knowledge distillation methods BIBREF6, with significant gain in training efficiency and storage reduction while maintaining comparable model accuracy to original large models. To the authors' best knowledge, this is the first known effort for BERT model compression.\nTo the authors' best knowledge, this is the first known effort for BERT model compression.",

They found that the predictive value of Flickr tags is roughly on a par with that of the scientific datasets, and that combining both types of information leads to significantly better results than using either of them alone.

It is commonly used to train and evaluate neural network models that generate image descriptions (e.g. BIBREF2 ). An untested assumption behind the dataset is that the descriptions are based on the images, and nothing else. Here are the authors (about the Flickr8K dataset, a subset of Flickr30K):\n“By asking people to describe the people, objects, scenes and activities that are shown in a picture without giving them any further information about the context in which the picture was taken, we were able to obtain conceptual descriptions that focus only on the information that can be obtained from the image alone.” BIBREF1 \nWhat this assumption overlooks is the amount of interpretation or recontextualization carried out by the annotators. Let us take a concrete example. Figure FIGREF1 shows an image from the Flickr30K dataset.\nThis image comes with the five descriptions below. All but the first one contain information that cannot come from the image alone. Relevant parts are highlighted in bold:\nWe need to understand that the descriptions in the Flickr30K dataset are subjective descriptions of events. This can be a good thing: the descriptions tell us what are the salient parts of each image to the average human annotator. So the two humans in Figure FIGREF1 are relevant, but the two soap dispensers are not. But subjectivity can also result in stereotypical descriptions, in this case suggesting that the male is more likely to be the manager, and the female is more likely to be the subordinate. rashtchian2010collecting do note that some descriptions are speculative in nature, which they say hurts the accuracy and the consistency of the descriptions. But the problem is not with the lack of consistency here. Quite the contrary: the problem is that stereotypes may be pervasive enough for the data to be consistently biased. And so language models trained on this data may propagate harmful stereotypes, such as the idea that women are less suited for leadership positions.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices. I will build on earlier work on linguistic bias in general BIBREF3 , providing examples from the Flickr30K data, and present a taxonomy of unwarranted inferences.

        "question": "What result does Ammanabrolu & Hausknecht get after they test their approach on Zork1?",
        "answer": "The combination of the knowledge graph and template action selection resulted in improvements over existing methods.",
        "evidence": "Many reinforcement learning algorithms are designed for relatively small discrete or continuous action spaces and so have trouble scaling. Text-adventure games—or interaction fictions—are simulations in which both an agents' state and action spaces are in textual natural language. An example of a one turn agent interaction in the popular text-game Zork1 can be seen in Fig. FIGREF1. Text-adventure games provide us with multiple challenges in the form of partial observability, commonsense reasoning, and a combinatorially-sized state-action space. Text-adventure games are structured as long puzzles or quests, interspersed with bottlenecks. The quests can usually be completed through multiple branching paths. However, games can also feature one or more bottlenecks. Bottlenecks are areas that an agent must pass through in order to progress to the next section of the game regardless of what path the agent has taken to complete that section of the quest BIBREF0. In this work, we focus on more effectively exploring this space and surpassing these bottlenecks—building on prior work that focuses on tackling the other problems.\nFormally, we use the definition of text-adventure games as seen in BIBREF1 and BIBREF2. These games are partially observable Markov decision processes (POMDPs), represented as a 7-tuple of $\\langle S,T,A,\\Omega , O,R, \\gamma \\rangle $ representing the set of environment states, mostly deterministic conditional transition probabilities between states, the vocabulary or words used to compose text commands, observations returned by the game, observation conditional probabilities, reward function, and the discount factor respectively. For our purposes, understanding the exact state and action spaces we use in this work is critical and so we define each of these in relative depth.\nAction-Space. To solve Zork1, the cannonical text-adventure games, requires the generation of actions consisting of up to five-words from a relatively modest vocabulary of 697 words recognized by the game’s parser. This results in $\\mathcal {O}(697^5)={1.64e14}$ possible actions at every step. To facilitate text-adventure game playing, BIBREF2 introduce Jericho, a framework for interacting with text-games. They propose a template-based action space in which the agent first selects a template, consisting of an action verb and preposition, and then filling that in with relevant entities $($e.g. $[get]$ $ [from] $ $)$. Zork1 has 237 templates, each with up to two blanks, yielding a template-action space of size $\\mathcal {O}(237 \\times 697^2)={1.15e8}$. This space is still far larger than most used by previous approaches applying reinforcement learning to text-based games.\nState-Representation. Prior work has shown that knowledge graphs are effective in terms of dealing with the challenges of partial observability $($BIBREF3 BIBREF3; BIBREF4$)$. A knowledge graph is a set of 3-tuples of the form $\\langle subject, relation, object \\rangle $. These triples are extracted from the observations using Stanford's Open Information Extraction (OpenIE) BIBREF5. Human-made text-adventure games often contain relatively complex semi-structured information that OpenIE is not designed to parse and so they add additional rules to ensure that the correct information is parsed. The graph itself is more or less a map of the world, with information about objects' affordances and attributes linked to the rooms that they are place in a map. The graph also makes a distinction with respect to items that are in the agent's possession or in their immediate surrounding environment. An example of what the knowledge graph looks like and specific implementation details can be found in Appendix SECREF14.\nBIBREF6 introduce the KG-A2C, which uses a knowledge graph based state-representation to aid in the section of actions in a combinatorially-sized action-space—specifically they use the knowledge graph to constrain the kinds of entities that can be filled in the blanks in the template action-space. They test their approach on Zork1, showing the combination of the knowledge graph and template action selection resulted in improvements over existing methods. They note that their approach reaches a score of 40 which corresponds to a bottleneck in Zork1 where the player is eaten by a “grue” (resulting in negative reward) if the player has not first lit a lamp. The lamp must be lit many steps after first being encountered, in a different section of the game; this action is necessary to continue exploring but doesn’t immediately produce any positive reward. That is, there is a long term dependency between actions that is not immediately rewarded, as seen in Figure FIGREF1. Others using artificially constrained action spaces also report an inability to pass through this bottleneck BIBREF7, BIBREF8. They pose a significant challenge for these methods because the agent does not see the correct action sequence to pass the bottleneck enough times. This is in part due to the fact that for that sequence to be reinforced, the agent needs to reach the next possible reward beyond the bottleneck.\nMore efficient exploration strategies are required to pass bottlenecks. Our contributions are two-fold. We first introduce a method that detects bottlenecks in text-games using the overall reward gained and the knowledge graph state. This method freezes the policy used to reach the bottleneck and restarts the training from there on out, additionally conducting a backtracking search to ensure that a sub-optimal policy has not been frozen. The second contribution explore how to leverage knowledge graphs to improve existing exploration algorithms for dealing with combinatorial action-spaces such as Go-Explore BIBREF9. We additionally present a comparative ablation study analyzing the performance of these methods on the popular text-game Zork1.\nThey test their approach on Zork1, showing the combination of the knowledge graph and template action selection resulted in improvements over existing methods.",

Hundreds of features generated at different linguistic levels are exploited to boost classification. With the success of deep learning, there has been much interest in applying deep neural network based techniques to further improve the prediction performances BIBREF3 , BIBREF4 , BIBREF5 .\nA key component of deep neural network is word embedding which serve as an lookup table to get word representations. From low level NLP tasks such as language modeling, POS tagging, name entity recognition, and semantic role labeling BIBREF6 , BIBREF7 , to high level tasks such as machine translation, information retrieval and semantic analysis BIBREF8 , BIBREF9 , BIBREF10 . Deep word representation learning has demonstrated its importance for these tasks. All the tasks get performance improvement via further learning either word level representations or sentence level representations. On the other hand, some researchers have found character-level convolutional networks BIBREF11 , BIBREF12 are useful in extracting information from raw signals for the task such as language modeling or text classification.\nIn this work, we focus on deep neural network based sentence relation modeling tasks. We explore treating each sentence as a kind of raw signal at character level, and applying temporal (one-dimensional) Convolution Neural Network (CNN) BIBREF6 , Highway Multilayer Perceptron (HMLP) and multi-layer bidirectional LSTM (Long Short Term Memory) BIBREF13 to learn sentence representations. We propose a new deep neural network architecture that jointly leverage pre-trained word embedding and character embedding to represent the meaning sentences. More specifically, our new approach first generates two kinds of word sequence representations. One kind of sequence representations are the composition of pre-trained word vectors. The other kind of sequence representation comprise word vectors that generating from character-level convolutional network. We then inject the two sequence representations into bidirectional LSTM, which means forward directional LSTM accept pre-trained word embedding output and backward directional LSTM accept auxiliary character CNN embedding output. The final sentence representation is the concatenation of the two direction. After that, we construct matching features followed by another temporal CNN to learn high-level hidden matching feature representations. Figure FIGREF1 shows the neural network architecture for general sentence relation modeling.\nOur model shows that when trained on small size datasets, combining pre-trained word embeddings with auxiliary character-level embedding can improve the sentence representation. Word embeddings can help capturing general word semantic meanings, whereas char-level embedding can help modeling task specific word meanings. Note that auxiliary character-level embedding based sentence representation do not require the knowledge of words or even syntactic structure of a language. The enhanced sentence representation generated by multi-layer bidirectional LSTM will encapsulate the character and word levels informations. Furthermore, it may enhance matching features that generated by computing similarity measures on sentence pairs. Quantitative evaluations on standard dataset demonstrate the effectiveness and advantages of our method.\nOur model shows that when trained on small size datasets, combining pre-trained word embeddings with auxiliary character-level embedding can improve the sentence representation.",

        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ).

SQuAD is much larger in size although questions in this corpus are often paraphrased multiple times. On the contrary, SQuAD's average candidates per question ( INLINEFORM0 ) is the smallest because SQuAD extracts answer candidates from paragraphs whereas the others extract them from sections or infoboxes that consist of bigger contexts. Although InfoboxQA is larger than WikiQA or SelQA, the number of token types ( INLINEFORM1 ) in InfoboxQA is smaller than those two, due to the repetitive nature of infoboxes.\nAll corpora show similar average answer candidate lengths ( INLINEFORM0 ), except for InfoboxQA where each line in the infobox is considered a candidate. SelQA and SQuAD show similar average question lengths ( INLINEFORM1 ) because of the similarity between their annotation schemes. It is not surprising that WikiQA's average question length is the smallest, considering their questions are taken from search queries. InfoboxQA's average question length is relatively small, due to the restricted information that can be asked from the infoboxes. InfoboxQA and WikiQA show the least question-answer word overlaps over questions and answers ( INLINEFORM2 and INLINEFORM3 in Table TABREF2 ), respectively.

The four wardens of the Goldsmiths’ Company were tasked with visiting workshops in the City of London to assay (test) silver articles. If these articles were found to be below standard they were originally forfeit to the king, but if they passed, each article received the king's mark of authentication which was the mark of a leopard's head. By 1478, there were several hundred workshops and merchants manufacturing silver articles in the City of London. It was not possible for the wardens to visit them all so the merchants were ordered to bring their items to Goldsmiths’ Hall for testing and marking and a permanent assay office was established in the building. This is the origin of the term hallmark – struck with the king's mark at Goldsmiths’ Hall.\n\nIn 1544 the Goldsmith's Company adopted the king's mark as their town mark and the mark of the leopard's head is now internationally recognized as the mark of this assay office.",

He is best known for his hit single \"She's All I Got\" and for being one of the inaugural artists signed to Clive Davis' J Records label.\n\nBiography\nThe son of Guyanese American jazz saxophonist Jimmy Cozier, and Dawn Cozier, a Jamaican born hair stylist. Cozier and his younger brother Malik were raised in Crown Heights, Brooklyn. Cozier was encouraged to sing as a child by his family, who would demand that he perform in group settings. He started out as a singer/songwriter for artists such as Mýa, Sinéad O'Connor, and Janet Jackson (whose hit \"Girlfriend/Boyfriend\" he co-wrote). He was a background vocalist for the Junior Mafia/Lil' Kim track \"Backstabbers\" and toured with Joe behind the latter's album All That I Am.\n\nWyclef Jean caught word of Cozier's talent thru Cozier manager Jacques “Haitian Jack” Agnant and had him meet with Clive Davis, who signed Cozier to J Records in 2000. His debut single \"She's All I Got\" was released in 2001, and rose to #26 on the Billboard Hot 100 and to #4 on the R&B chart.\n\nFollowing the success of the single, his self-titled debut album was released on July 9, 2001 and hit the Billboard Top 200 at #65 and #15 on the R&B Albums chart. A follow-up single \"So Much to Lose\" was released later in the year, and peaked at #123 on the R&B chart. He also appeared on labelmate Alicia Keys' debut Songs in A Minor on the track \"Mr. Man\" which he co-wrote, and \"Turn Around\" with other labelmate Olivia, on her self-titled debut album.\n\nHe began writing songs for other artists such as Chris Brown, Olivia and Cheri Dennis in the years since. After the folding of J Records, he became an independent artist, creating his own label, Cozi Music Inc.\n\nIn 2007, he announced work on a new album, releasing two singles, \"U Got Them Goods\" and \"You\", that year. Continued work on his sophomore album stretched through 2010.\n\nHis second album, Way of Life was announced in 2010, led by the single \"Tonight\" which was released on March 2, 2010. The album was released on March 16, 2010.\n\nIn 2013, he collaborated with Sean Paul for his single \"Always Be My Lady\" which was released on August 2. Additionally, he released a single \"Girls Girls\" that year.\n\nThe next year, he premiered a new single \"Choose Me\" featuring Shaggy and announced his third album would be titled R&B (Reggae & Blues) set for a 2015 release. Following the single, he collaborated with artists such as Gyptian, Elephant Man, Shaggy, Red Fox, Melissa Musique on various compilation albums. One of those collaborations, \"Special Girl (Remix)\" was released as a single in 2014.\n\nHis third album, titled Get Cozi was released on December 9, 2016.

        "answer": "There are both advantages and disadvantages from working from home, and they apply differently to different people depending on the person's personality, family situation, location, and job description. Some key advantages are the ability to develop closer personal relationships with team members, have the opportunity for more spontaneous casual conversations, and experience more productive meetings because of the ability to read people's body language and to see presentation materials more clearly. Many people will experience better mental health by going into the office and establishing a sense of greater connection with team members. In addition, certain employees will take advantage of remote work to use work time to engage in personal activities rather than real work, to the detriment of the employer. Some disadvantages of going into the office include the time inefficiency from commuting, the cost of commuting, the time inefficiency that occurs from experiencing all the social chatting that occurs in the office, and the hassle of having to schedule conference rooms. Commuting also contributes to global warming through the greater use of fossil fuels.

The expedition encounters an entity within the topological anomaly that \"writes\" living words of non-sense on the wall of the anomaly in fungus. \n\nEarly in the expedition, the biologist is contaminated by the fungus of the words in the anomaly, which grants her immunity to hypnotic suggestion, which the psychologist uses to control the other members of the expedition.

The psychologist jumps from the lighthouse, presumably forced to by the entity behind Area X, but lives long enough to confront the biologist.

We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation.

        "question": "What problem does BERT’s bi-directional context pose?",
        "answer": "To calculate an auto-regressive joint probability.",
        "evidence": "The goal of an language model is to assign meaningful probabilities to a sequence of words. Given a set of tokens $\\mathbf {X}=(x_1,....,x_T)$, where $T$ is the length of a sequence, our task is to estimate the joint conditional probability $P(\\mathbf {X})$ which is\nwere $(x_{1}, \\ldots , x_{i-1})$ is the context. An Intrinsic evaluation of the performance of Language Models is perplexity (PPL) which is defined as the inverse probability of the set of the tokens and taking the $T^{th}$ root were $T$ is the number of tokens\nIn our two approaches we use transformer based architectures: BERT and Transformer-XL as mentioned before. Calculating the auto-regressive $P(\\mathbf {X})$ for the transformer-XL is quite straight-forward as the model is unidirectional but it doesn't factorize the same way for a bi-directional model like BERT.\nBERT's bi-directional context poses a problem for us to calculate an auto-regressive joint probability. A simple fix could be that we mask all the tokens $\\mathbf {x}_{>i}$ and we calculate the conditional factors as we do for an unidirectional model. By doing so though, we loose upon the advantage of bi-directional context the BERT model enables. We propose an approximation of the joint probability as,\nThis type of approximations has been previously explored with Bi-directional RNN LM's BIBREF9 but not for deep transformer models. We therefore, define a pseudo-perplexity score from the above approximated joint probability.\nThe original BERT has two training objectives: 'Masked language modelling', in which you mask input tokens randomly and then predict the masked tokens using the left and right context. Additionally, there is the 'next sentence prediction' task that jointly trains text-pair representations. For training the Masked language model the original BERT used Byte Pair Encoding (BPE) BIBREF10 for subword tokenization BIBREF11.For example the rare word \"unaffable\" to be split up into more frequent subwords such as [\"un\", \"##aff\", \"##able\"]. To remain consistent with experiments performed with LSTM's we use the morfessor for the subword tokenization in the Finnish Language. In Addition, we also apply boundary markers as in (Table TABREF7) and train two separate models using this distinction. We train with left-marked markings as the original BERT was trained with such a scheme and the left+right-marked as it was the previous SOTA with the Finnish Language. For the transformer-XL experiments, we just train with the left+right marked scheme.\nThe Next Sentence Prediction (NSP) is a binary classification task which predicts whether two segments follow each other in the original text. This pre-training task was proposed to further improve the performance on downstreaming tasks, like Natural Language Inference(NLI) but in reality removing the NSP loss matches or slightly improves the downstream task performance BIBREF12. In this paper, we have omitted the NSP task from the BERT pre-training procedure and changed the input from a SEGMENT-PAIR input to a SINGLE SEGMENT input. As seen in (Fig FIGREF8)\nTransformer-XL introduced the notion of recurrence in self-attention by caching the hidden state sequence to compute the hidden states of a new segment. It also introduces a novel relative positional embedding scheme and both of them combined address the issue of fixed context lengths. Transformer-XL as mentioned is a unidirectional deep transformer architecture, therefore the perplexity can be calculated as (Eq DISPLAY_FORM5). The only change is in the input format, were we use sub-word units rather than whole word units as Finnish is morphologically richer than English.\nBERT’s bi-directional context poses a problem for us to calculate an auto-regressive joint probability.",

All fifty states and the District of Columbia were part of the 1972 United States presidential election. Voters chose 12 electors to the Electoral College, who voted for president and vice president.\n\nMissouri was won by the Republican nominees, incumbent President Richard Nixon of California and his running mate Vice President Spiro Agnew of Maryland. Nixon and Agnew defeated the Democratic nominees, Senator George McGovern of South Dakota and his running mate U.S. Ambassador Sargent Shriver of Maryland.\n\nIn a state substantially part of the conservative South, McGovern was viewed by many voters as a left-wing extremist because of his support for busing and civil rights, plus his opposition to the Vietnam War, support for granting amnesty to draft dodgers and support for a thousand-dollar giveaway to each American as a solution to poverty. Many, especially Republican campaigners, also believed McGovern would legalise abortion and illicit drugs if he were elected – despite the fact that his running mate Sargent Shriver was firmly opposed to abortion. These fears of McGovern's social radicalism were especially pronounced amongst poorer whites, who were abundant in the southern part of Missouri.\n\nNixon carried Missouri with 62.29% of the vote to McGovern's 37.71%, a victory margin of 24.58%.

        "question": "What approach does the author use to incorporate the relationship between these factors and tweet sentiments into standard n-gram-based Twitter sentiment classification?",
        "answer": "A Bayesian approach.",
        "evidence": "Twitter is a micro-blogging platform and a social network where users can publish and exchange short messages of up to 140 characters long (also known as tweets). Twitter has seen a great rise in popularity in recent years because of its availability and ease-of-use. This rise in popularity and the public nature of Twitter (less than 10% of Twitter accounts are private BIBREF0 ) have made it an important tool for studying the behaviour and attitude of people.\nOne area of research that has attracted great attention in the last few years is that of tweet sentiment classification. Through sentiment classification and analysis, one can get a picture of people's attitudes about particular topics on Twitter. This can be used for measuring people's attitudes towards brands, political candidates, and social issues.\nThere have been several works that do sentiment classification on Twitter using standard sentiment classification techniques, with variations of n-gram and bag of words being the most common. There have been attempts at using more advanced syntactic features as is done in sentiment classification for other domains BIBREF1 , BIBREF2 , however the 140 character limit imposed on tweets makes this hard to do as each article in the Twitter training set consists of sentences of no more than several words, many of them with irregular form BIBREF3 .\nOn the other hand, what tweets lack in structure they make up with sheer volume and rich metadata. This metadata includes geolocation, temporal and author information. We hypothesize that sentiment is dependent on all these contextual factors. Different locations, times and authors have different emotional valences. For instance, people are generally happier on weekends and certain hours of the day, more depressed at the end of summer holidays, and happier in certain states in the United States. Moreover, people have different baseline emotional valences from one another. These claims are supported for example by the annual Gallup poll that ranks states from most happy to least happy BIBREF4 , or the work by Csikszentmihalyi and Hunter BIBREF5 that showed reported happiness varies significantly by day of week and time of day. We believe these factors manifest themselves in sentiments expressed in tweets and that by accounting for these factors, we can improve sentiment classification on Twitter.\nIn this work, we explored this hypothesis by utilizing distant supervision BIBREF6 to collect millions of labelled tweets from different locations (within the USA), times of day, days of the week, months and authors. We used this data to analyse the variation of tweet sentiments across the aforementioned categories. We then used a Bayesian approach to incorporate the relationship between these factors and tweet sentiments into standard n-gram based Twitter sentiment classification.\nThis paper is structured as follows. In the next sections we will review related work on sentiment classification, followed by a detailed explanation of our approach and our data collection, annotation and processing efforts. After that, we describe our baseline n-gram sentiment classifier model, followed by the explanation of how the baseline model is extended to incorporate contextual information. Next, we describe our analysis of the variation of sentiment within each of the contextual categories. We then evaluate our models and finally summarize our findings and contributions and discuss possible paths for future work.\nWe then used a Bayesian approach to incorporate the relationship between these factors and tweet sentiments into standard n-gram based Twitter sentiment classification.

        "question": "How to collect tweets by the authors?",
        "answer": "The authors collected tweets associated to a dozen US mainstream news websites with the Streaming API and referred to Hoaxy API for what concerns tweets containing links to 100+ US disinformation outlets.",
        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31.

        "question": "What is the book \"The Sun Also Rises\" about?",
        "evidence": "The Sun Also Rises is a 1926 novel by American writer Ernest Hemingway, his first, that portrays American and British expatriates who travel from Paris to the Festival of San Fermín in Pamplona to watch the running of the bulls and the bullfights. An early modernist novel, it received mixed reviews upon publication. Hemingway biographer Jeffrey Meyers writes that it is now \"recognized as Hemingway's greatest work\" and Hemingway scholar Linda Wagner-Martin calls it his most important novel. The novel was published in the United States in October 1926 by Scribner's. A year later, Jonathan Cape published the novel in London under the title Fiesta. It remains in print.\n\nThe novel is a roman à clef: the characters are based on people in Hemingway's circle and the action is based on events, particularly Hemingway's life in Paris in the 1920s and a trip to Spain in 1925 for the Pamplona festival and fishing in the Pyrenees. Hemingway presents his notion that the \"Lost Generation\"—considered to have been decadent, dissolute and irretrievably damaged by World War I—was in fact resilient and strong. Hemingway investigates the themes of love and death, the revivifying power of nature and the concept of masculinity. His spare writing style, combined with his restrained use of description to convey characterizations and action, demonstrates his \"Iceberg Theory\" of writing.",

        "evidence": "Spoken language understanding (SLU) systems infer the meaning or intent of a spoken utterance BIBREF0 . This is crucial for voice user interfaces, in which the speaker's utterance needs to be converted into an action or query. For example, for a voice-controlled coffee machine, an utterance like “make me a large coffee with two milks and a sugar, please” might have an intent representation like {drink: \"coffee\", size: \"large\", additions: [{type: \"milk\", count: 2}, {type: \"sugar\", count: 1}]}.\nThe conventional SLU pipeline is composed of two modules: an automatic speech recognition (ASR) module that maps the speech to a text transcript, and a natural language understanding (NLU) module that maps the text transcript to the speaker's intent BIBREF1 , BIBREF2 , BIBREF3 . An alternative approach that is beginning to gain popularity is end-to-end SLU BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 . In end-to-end SLU, a single trainable model maps the speech audio directly to the speaker's intent without explicitly producing a text transcript (Fig. FIGREF4 ). Unlike the conventional SLU pipeline, end-to-end SLU:\nEnd-to-end models have been made possible by deep learning, which automatically learns hierarchical representations of the input signal BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . Speech is natural to represent in a hierarchical way: waveform INLINEFORM0 phonemes INLINEFORM1 morphemes INLINEFORM2 words INLINEFORM3 concepts INLINEFORM4 meaning. However, because speech signals are high-dimensional and highly variable even for a single speaker, training deep models and learning these hierarchical representations without a large amount of training data is difficult.\nThe computer vision BIBREF14 , BIBREF15 , natural language processing BIBREF16 , BIBREF17 , BIBREF18 , BIBREF19 , BIBREF20 , and ASR BIBREF21 , BIBREF22 communities have attacked the problem of limited supervised training data with great success by pre-training deep models on related tasks for which there is more training data.

        "answer": "The World Event Interaction Survey (WEIS) and the Conflict and Peace Data Bank (COPDAB).",
        "evidence": "Political event data has existed in various forms since the 1970s. Two of the most common political event datasets were the World Event Interaction Survey (WEIS) and the Conflict and Peace Data Bank (COPDAB) BIBREF0 , BIBREF1 . These two datasets were eventually replaced by the projects created by Philip Schrodt and various collaborators. In general, these projects were marked by the use of the Conflict and Mediation Event Observations (CAMEO) coding ontology and automated, machine-coding rather than human coding BIBREF2 , BIBREF3 . The CAMEO ontology is made up of 20 “top-level” categories that encompass actions such as “Make Statement” or “Protest”, and contains over 200 total event classifications. This ontology has served as the basis for most of the modern event datasets such as the Integrated Crisis Early Warning System (ICEWS) BIBREF4 , the Global Database of Events, Language, and Tone (GDELT), and the Phoenix dataset presented in this paper.\nThis type of data can prove highly useful for many types of studies. Since this type of data is inherently atomic, each observation is a record of a single event between a source and a target, it provides a disaggregated view of political events. This means that the data can be used to examine interactions below the usual monthly or yearly levels of aggregation. This approach can be used in a manner consistent with traditional hypothesis testing that is the norm in political science BIBREF5 , BIBREF6 , BIBREF7 . Additionally, event data has proven useful in forecasting models of conflict since the finer time resolution allows analysts to gain better leverage over the prediction problem than is possible when using more highly aggregated data BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . Finally, the advent of daily-updated event data has led to many novel uses such as watchboarding or dashboarding. The goal in these situations is to provide an easy to understand interface that analysts can use to quickly monitor ongoing or emerging situations around the world. These applications provide a new frontier for event data that has not been considered much until this point.\nThe status quo of TABARI-generated, CAMEO-coded event data, which was established in the early 2000s, has remained with little change. BIBREF12 outlined many potential advances in the generation of political event data. These advances are things such as realtime processing of news stories, the incorporation of open-source natural language processing (NLP) software, and enhancements in the automated coding structure. Two publicly-available datasets, GDELT and ICEWS, have each attempted to implement some, or all, of these changes in their respective data-generating pipelines. In terms of goals, the ICEWS project seems closest to sharing the vision of the Phoenix dataset. A more in-depth comparison of Phoenix and ICEWS is presented in a later section. In short, the goal of the project presented in this chapter is to implement most of the improvements suggested in BIBREF12 .\nPolitical event data has existed in various forms since the 1970s.

        "evidence": "For an ever increasing spectrum of applications (e.g., medical text analysis, opinion mining, sentiment analysis, social media text analysis, customer intelligence, fraud analytics etc.) mining and analysis of unstructured natural language text data is necessary BIBREF0, BIBREF1, BIBREF2.\nOne of key challenge while designing such text analytics (TA) applications is to identify right set of features. For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nProposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.",

The primary objective of CLIR is to translate or project a query into the language of the document repository BIBREF1 , which we refer to as Retrieval Corpus (RC). To this end, common CLIR approaches translate search queries using a Machine Translation (MT) model and then use a monolingual IR system to retrieve from RC. In this process, a translation model is treated as a black box BIBREF2 , and it is usually trained on a sentence level parallel corpus, which we refer to as Translation Corpus (TC).\nWe address a pitfall of using existing MT models for query translation BIBREF1 . An MT model trained on TC does not have any knowledge of RC. In an extreme setting, where there are no common terms between the target side of TC and RC, a well trained and tested translation model would fail because of vocabulary mismatch between the translated query and documents of RC. Assuming a relaxed scenario where some commonality exists between two corpora, a translation model might still perform poorly, favoring terms that are more likely in TC but rare in RC. Our hypothesis is that a search query translation model would perform better if a translated query term is likely to appear in the both retrieval and translation corpora, a property we call balanced translation.\nTo achieve balanced translations, it is desired to construct an MT model that is aware of RC vocabulary. Different types of MT approaches have been adopted for CLIR task, such as dictionary-based MT, rule-based MT, statistical MT etc. BIBREF3 . However, to the best of our knowledge, a neural search query translation approach has yet to be taken by the community. NMT models with attention based encoder-decoder techniques have achieved state-of-the-art performance for several language pairs BIBREF4 . We propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT). RAT is inspired from two word embedding learning approaches: Relevance-based Word Embedding (RWE) BIBREF5 and Continuous Bag of Words (CBOW) embedding BIBREF6 . We show that learning NMT with RAT enables it to generate balanced translation.\nNMT models learn to encode the meaning of a source sentence and decode the meaning to generate words in a target language BIBREF7 . In the proposed multi-task learning model, RAT shares the decoder embedding and final representation layer with NMT. Our architecture answers the following question: In the decoding stage, can we restrict an NMT model so that it does not only generate terms that are highly likely in TC?. We show that training a strong baseline NMT with RAT roughly achieves 16% improvement over the baseline. Using a qualitative analysis, we further show that RAT works as a regularizer and prohibits NMT to overfit to TC vocabulary.\nThe primary objective of CLIR is to translate or project a query into the language of the document repository (Sokokov et al., 2013), which we refer to as Retrieval Corpus (RC).",

        "evidence": "In this section, we provide comparative results on our new Multilingual Document Classification Corpus. Since the initial work by BIBREF0 many alternative approaches to cross-lingual document classification have been developed. We will encourage the respective authors to evaluate their systems on MLDoc. We believe that a large variety of transfer language pairs will give valuable insights on the performance of the various approaches.\nIn this paper, we propose initial strong baselines which represent two complementary directions of research: one based on the aggregation of multilingual word embeddings, and another one, which directly learns multilingual sentence representations. Details on each approach are given in section \"Multilingual word representations\" and \"Multilingual sentence representations\" respectively. In contrast to previous works on cross-lingual document classification with RVC2, we explore training the classifier on all languages and transfer it to all others, ie. we do not limit our study to the transfer between English and a foreign language.\nOne can envision several ways to define cross-lingual document classification, in function of the resources which are used in the source and transfer language (see Table 3 ). The first scheme assumes that we have no resources in the transfer language at all, neither labeled nor unlabeled. We will name this case “zero-shot cross-lingual document classification”. To simplify the presentation, we will assume that we transfer from English to German. The training and evaluation protocol is as follows. First, train a classifier using resources in the source language only, eg. the training and development corpus are in English. All meta parameters and model choices are performed using the English development corpus. Once the best performing model is selected, it is applied to the transfer language, eg. the German test set. Since no resources of the transfer language are used, the same system can be applied to many different transfer languages. This type of cross-lingual document classification needs a very strong multilingual representation since no knowledge on the target language was used during the development of the classifier.\nIn a second class of cross-lingual document classification, we may aim in improving the transfer performance by using a limited amount of resources in the target language. In the framework of the proposed MLDoc we will use the development corpus of target language for model selection. We will name this method “targeted cross-lingual document classification” since the system is tailored to one particular transfer language. It is unlikely that this system will perform well on other languages than the ones used for training or model selection.\nIf the goal is to build one document classification system for many languages, it may be interesting to use already several languages during training and model selection. To allow a fair comparison, we will assume that these multilingual resources have the same size than the ones used for zero-shot or targeted cross-language document classification, e.g. a training set composed of five languages with 200 examples each. This type of training is not a cross-lingual approach any more. Consequently, we will refer to this method as “joint multilingual document classification”.\nWe will name this method “targeted cross-lingual document classification” since the system is tailored to one particular transfer language.",

        "answer": "The hypothesis is that language varieties differ mainly in lexicographic clues.",
        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nWe are interested in discovering which kind of features capture higher differences among varieties.

        "question": "What are the weaknesses of their proposed interpretability quantification method?",
        "answer": "can be biased by dataset used and may generate categories which are suboptimal compared to human designed categories",
        "evidence": "Our interpretability measurements are based on our proposed dataset SEMCAT, which was designed to be a comprehensive dataset that contains a diverse set of word categories. Yet, it is possible that the precise interpretability scores that are measured here are biased by the dataset used. In general, two main properties of the dataset can affect the results: category selection and within-category word selection. To examine the effects of these properties on interpretability evaluations, we create alternative datasets by varying both category selection and word selection for SEMCAT. Since SEMCAT is comprehensive in terms of the words it contains for the categories, these datasets are created by subsampling the categories and words included in SEMCAT. Since random sampling of words within a category may perturb the capacity of the dataset in reflecting human judgement, we subsample r% of the words that are closest to category centers within each category, where $r \\in \\lbrace 40,60,80,100\\rbrace $ . To examine the importance of number of categories in the dataset we randomly select $m$ categories from SEMCAT where $m \\in \\lbrace 30,50,70,90,110\\rbrace $ . We repeat the selection 10 times independently for each $m$ .\nIn contrast to the category coverage, the effects of within-category word coverage on interpretability scores can be more complex. Starting with few words within each category, increasing the number of words is expected to more uniformly sample from the word distribution, more accurately reflect the semantic relations within each category and thereby enhance interpretability scores. However, having categories over-abundant in words might inevitably weaken semantic correlations among them, reducing the discriminability of the categories and interpretability of the embedding. Table 3 shows that, interestingly, changing the category coverage has different effects on the interpretability scores of different types of embeddings. As category word coverage increases, interpretability scores for random embedding gradually decrease while they monotonically increase for the GloVe embedding. For semantic spaces $\\mathcal {I}$ and $\\mathcal {I}^*$ , interpretability scores increase as the category coverage increases up to 80 $\\%$ of that of SEMCAT, then the scores decrease. This may be a result of having too comprehensive categories as argued earlier, implying that categories with coverage of around 80 $\\%$ of SEMCAT are better suited for measuring interpretability. However, it should be noted that the change in the interpretability scores for different word coverages might be effected by non-ideal subsampling of category words. Although our word sampling method, based on words' distances to category centers, is expected to generate categories that are represented better compared to random sampling of category words, category representations might be suboptimal compared to human designed categories.\nYet, it is possible that the precise interpretability scores that are measured here are biased by the dataset used.\nHowever, it should be noted that the change in the interpretability scores for different word coverages might be effected by non-ideal subsampling of category words.

It was used by enslaved African Americans primarily to escape into free states and Canada. The network was assisted by abolitionists and others sympathetic to the cause of the escapees. The enslaved persons who risked escape and those who aided them are also collectively referred to as the \"Underground Railroad\". Various other routes led to Mexico, where slavery had been abolished, and to islands in the Caribbean that were not part of the slave trade. An earlier escape route running south toward Florida, then a Spanish possession (except 1763–1783), existed from the late 17th century until approximately 1790. However, the network now generally known as the Underground Railroad began in the late 18th century. It ran north and grew steadily until the Emancipation Proclamation was signed by President Abraham Lincoln. One estimate suggests that by 1850, approximately 100,000 enslaved people had escaped to freedom via the network",

        "evidence": "Automated deriving discourse relation from free text is a challenging but im-portant problem. The shallow discourse parsing is very useful in the text summariza-tion BIBREF0 , opinion analysis BIBREF1 and natural language generation. Shallow discourse parser is the system of parsing raw text into a set of discourse relations between two adjacent or non-adjacent text spans. Discourse relation is composed of a discourse connective, two arguments of the discourse connective and the sense of the discourse connective. Discourse connective signals the explicit dis-course relation, but in non-explicit discourse relation, a discourse connective is omit-ted. Two arguments of the discourse connective, Arg1 and Arg2, which are the two adjacent or non-adjacent text spans connecting in the discourse relation. The sense of the discourse connective characterizes the nature of the discourse relations. The following discourse relation annotation is taken from the document in the PDTB. Arg1 is shown in italicized, and Arg2 is shown in bold. The discourse connective is underlined.\nThe connective identifier finds the connective word, “unless”. The arguments identifier locates the two arguments of “unless”. The sense classifier labels the dis-course relation. The non-explicit identifier checks all the pair of adjacent sentences. If the non-explicit identifier indentifies the pair of sentences as non-explicit relation, it will label it the relation sense. Though many research work BIBREF2 , BIBREF3 , BIBREF4 are committed to the shallow discourse parsing field, all of them are focus on the subtask of parsing only rather than the whole parsing process. Given all that, a full shallow discourse parser framework is proposed in our paper to turn the free text into discourse relations set. The parser includes connective identifier, arguments identifier, sense classifier and non-explicit identifier, which connects with each other in pipeline. In order to enhance the performance of the parser, the feature-based maximum entropy model approach is adopted in the experiment. Maximum entropy model offers a clean way to combine diverse pieces of contextual evidence in order to estimate the probability of a certain linguistic class occurring with a certain linguistic context in a simple and accessible manner. The three main contributions of the paper are:\nThe rest of this paper is organized as follows. Section 2 reviews related work in discourse parsing. Section 3 describes the experimental corpus–PDTB. Section 4 de-scribes the framework and the components of the parser. Section 5 presents experi-ments and evaluations.

In this section, we first describe our problem setup and key terminologies by discussing the dataset used. Later, we formalize our problem definition.\nDataset: For our explorations, we use the Craigslist Bargaining dataset (CB) introduced by BIBREF4. Instead of focusing on the previously studied game environments BIBREF5, BIBREF6, the dataset considers a more realistic setup: negotiating the price of products listed on Craigslist. The dataset consists of 6682 dialogues between a buyer and a seller who converse in natural language to negotiate the price of a given product (sample in Table TABREF1). In total, 1402 product ad postings were scraped from Craigslist, belonging to six categories: phones, bikes, housing, furniture, car and electronics. Each ad posting contains details such as Product Title, Category Type and a Listing Price. Moreover, a secret target price is also pre-decided for the buyer. The final price after the agreement is called the Agreed Price, which we aim to predict.\nDefining the problem: Say we are provided with a product scenario $S$, a tuple: (Category, Title, Listing Price, Target Price). Define the interactions between a buyer and seller using a sequence of $n$ events $E_n:<e_{1}, e_{2}, ..., e_{n}>$, where $e_{i}$ occurs before $e_{j}$ iff $i<j$. Event $e_{i}$ is also a tuple: (Initiator, Type, Data). Initiator is either the Buyer or Seller, Type can be one of (message, offer, accept, reject or quit) and Data consists of either the corresponding natural language dialogue, offer price or can be empty. Nearly $80\\%$ of events in CB dataset are of type `message', each consisting a textual message as Data. An offer is usually made and accepted at the end of each negotiation. Since the offers directly contain the agreed price (which we want to predict), we only consider `message' events in our models. Given the scenario $S$ and first $n$ events $E_n$, our problem is then to learn the function $f_{n}$: $A = f_{n}(S, E_n)$ where $A$ refers to the final agreed price between the two negotiating parties.\n\nEach posting contains the title, category, a target for the seller (called listing price), and a secret target for the buyer (called target price).

        "answer": "Retail banking, also known as consumer banking or personal banking, is the provision of services by a bank to the general public, rather than to companies, corporations or other banks, which are often described as wholesale banking. Banking services which are regarded as retail include provision of savings and transactional accounts, mortgages, personal loans, debit cards, and credit cards. Retail banking is also distinguished from investment banking or commercial banking. It may also refer to a division or department of a bank which deals with individual customers.\n\nIn the U.S., the term commercial bank is used for a normal bank to distinguish it from an investment bank. After the Great Depression, the Glass–Steagall Act restricted normal banks to banking activities, and investment banks to capital market activities. That distinction was repealed in the 1990s. Commercial bank can also refer to a bank or a division of a bank that deals mostly with deposits and loans from corporations or large businesses, as opposed to individual members of the public (retail banking).",

        "question": "Does their approach improve the classification results in the hard task of multiclass assessment?",
        "answer": "Yes.",
        "evidence": "As observed by a recent article of Nature News BIBREF0 , “Wikipedia is among the most frequently visited websites in the world and one of the most popular places to tap into the world's scientific and medical information\". Despite the huge amount of consultations, open issues still threaten a fully confident fruition of the popular online open encyclopedia.\nA first issue relates to the reliability of the information available: since Wikipedia can be edited by anyone, regardless of their level of expertise, this tends to erode the average reputation of the sources, and, consequently, the trustworthiness of the contents posted by those sources. In an attempt to fix this shortcoming, Wikipedia has recently enlisted the help of scientists to actively support the editing on Wikipedia BIBREF0 . Furthermore, lack of control may lead to the publication of fake Wikipedia pages, which distort the information by inserting, e.g., promotional articles and promotional external links. Fighting vandalism is one of the main goals of the Wikimedia Foundation, the nonprofit organization that supports Wikipedia: machine learning techniques have been considered to offer a service to “judge whether an edit was made in good faith or not\" BIBREF1 . Nonetheless, in the past recent time, malicious organisations have acted disruptively with purposes of extortion - see, e.g., the recent news on the uncovering of a blackmail network of accounts, which threatened celebrities with the menace of inserting offending information on their Wikipedia pages.\nSecondly, articles may suffer from readability issues: achieving a syntactical accuracy that helps the reader with a fluid reading experience is —quite obviously— a property which articles should fulfill. Traditionally, the literature has widely adopted well known criteria, as the “Flesch-Kincaid\" measure\" BIBREF2 , to automatically assess readability in textual documents. More recently, new techniques have been proposed too, for assessing the readability of natural languages (see, e.g., BIBREF3 for the Italian use case, BIBREF4 for the Swedish one, BIBREF5 for English).\nIn this paper, we face the quest for quality assessment of a Wikipedia article, in an automatic way that comprehends not only readability and reliability criteria, but also additional parameters testifying completeness of information and coherence with the content one expects from an article dealing with specific topics, plus sufficient insights for the reader to elaborate further on some argument. The notion of data quality we deal with in the paper is coherent with the one suggested by recent contributions (see, e.g., BIBREF6 ), which points out like the quality of Web information is strictly connected to the scope for which one needs such information.\nOur intuition is that groups of articles related to a specific topic and falling within specific scopes are intrinsically different from other groups on different topics within different scopes. We approach the article evaluation through machine learning techniques. Such techniques are not new to be employed for automatic evaluation of articles quality. As an example, the work in BIBREF7 exploits classification techniques based on structural and linguistic features of an article. Here, we enrich that model with novel features that are domain-specific. As a running scenario, we focus on the Wikipedia medical portal. Indeed, facing the problems of information quality and ensuring high and correct levels of informativeness is even more demanding when health aspects are involved. Recent statistics report that Internet users are increasingly searching the Web for health information, by consulting search engines, social networks, and specialised health portals, like that of Wikipedia. As pointed out by the 2014 Eurobarometer survey on European citizens' digital health literacy, around six out of ten respondents have used the Internet to search for health-related information. This means that, although the trend in digital health literacy is growing, there is also a demand for a qualified source where people can ask and find medical information which, to an extent, can provide the same level of familiarity and guarantees as those given by a doctor or a health professional.\nWe anticipate here that leveraging new domain-specific features is in line with this demand of articles quality. Moreover, as the outcomes of our experiments show, they effectively improve the classification results in the hard task of multi-class assessment, especially for those classes that other automatic approaches worst classify. Remarkably, our proposal is general enough to be easily extended to other domains, in addition to the medical one.\nSection \"Dataset\" first describes the structure of the articles present in the medical portal. Then, it gives details on the real data used in the experiments, which are indeed articles extracted from the medical portal and labeled according to the manual assessment by the Wikimedia project. Section \"Baseline: the actionable model\" briefly presents the actionable model in BIBREF7 : we adopt it as the baseline for our analysis. In Section \"The medical domain model\" , we present the domain-specific, medical model we newly adopt in this paper as an extension of the baseline. The extended model includes features specifically extracted from the medical domain. One novel feature is based on the article textual content. Section \"Bio-medical entities\" presents the process which its extraction relies on, with a non trivial analysis of natural language and domain knowledge. Section \"Experiments and results\" presents experiments and results, with a comparison of the baseline model with the new one. In Section \"Related work\" , we survey related work in the area and in Section \"Conclusions\" we conclude the paper.\nMoreover, as the outcomes of our experiments show, they effectively improve the classification results in the hard task of multiclass assessment, especially for those classes that other automatic approaches worst classify.",

There are several examples of this in other countries throughout history. That being said, there are just as many examples of countries indicting former presidents without any sign of abuse. In fact, it can be an important part of the \"checks and balances\" of a democracy (see France, South Korea, etc.) One of the factors you can look at when determining if the justice system is being abused or not is the number of cases/indictments being brought against the former head of government. When the number of cases is low, there is a higher likelihood of abuse. But when the number of cases is high and for a diverse number of reasons, the likelihood of abuse is lower.",

        "question": "What is the drawback of existing approaches to predict implicit discourse relations?",
        "answer": "Most of existing approaches ignore wider paragraph-level contexts beyond the two discourse units that are examined for predicting a discourse relation in between.",
        "evidence": "PDTB-style discourse relations, mostly defined between two adjacent text spans (i.e., discourse units, either clauses or sentences), specify how two discourse units are logically connected (e.g., causal, contrast). Recognizing discourse relations is one crucial step in discourse analysis and can be beneficial for many downstream NLP applications such as information extraction, machine translation and natural language generation.\nCommonly, explicit discourse relations were distinguished from implicit ones, depending on whether a discourse connective (e.g., “because” and “after”) appears between two discourse units BIBREF0 . While explicit discourse relation detection can be framed as a discourse connective disambiguation problem BIBREF1 , BIBREF2 and has achieved reasonable performance (F1 score $>$ 90%), implicit discourse relations have no discourse connective and are especially difficult to identify BIBREF3 , BIBREF2 , BIBREF4 . To fill the gap, implicit discourse relation prediction has drawn significant research interest recently and progress has been made BIBREF5 , BIBREF6 by modeling compositional meanings of two discourse units and exploiting word interactions between discourse units using neural tensor networks or attention mechanisms in neural nets. However, most of existing approaches ignore wider paragraph-level contexts beyond the two discourse units that are examined for predicting a discourse relation in between.\nTo further improve implicit discourse relation prediction, we aim to improve discourse unit representations by positioning a discourse unit (DU) in its wider context of a paragraph. The key observation is that semantic meaning of a DU can not be interpreted independently from the rest of the paragraph that contains it, or independently from the overall paragraph-level discourse structure that involve the DU. Considering the following paragraph with four discourse relations, one relation between each two adjacent DUs:\n(1): [The Butler, Wis., manufacturer went public at $15.75 a share in August 1987,] $_{DU1}$ and (Explicit-Expansion) [Mr. Sim's goal then was a $29 per-share price by 1992.] $_{DU2}$ (Implicit-Expansion) [Strong earnings growth helped achieve that price far ahead of schedule, in August 1988.] $_{DU3}$ (Implicit-Comparison) [The stock has since softened, trading around $25 a share last week and closing yesterday at $23 in national over-the-counter trading.] $_{DU4}$ But (Explicit-Comparison) [Mr. Sim has set a fresh target of $50 a share by the end of reaching that goal.] $_{DU5}$ \nClearly, each DU is an integral part of the paragraph and not independent from other units. First, predicting a discourse relation may require understanding wider paragraph-level contexts beyond two relevant DUs and the overall discourse structure of a paragraph. For example, the implicit “Comparison” discourse relation between DU3 and DU4 is difficult to identify without the background information (the history of per-share price) introduced in DU1 and DU2. Second, a DU may be involved in multiple discourse relations (e.g., DU4 is connected with both DU3 and DU5 with a “Comparison” relation), therefore the pragmatic meaning representation of a DU should reflect all the discourse relations the unit was involved in. Third, implicit discourse relation prediction should benefit from modeling discourse relation continuity and patterns in a paragraph that involve easy-to-identify explicit discourse relations (e.g., “Implicit-Comparison” relation is followed by “Explicit-Comparison” in the above example).\nFollowing these observations, we construct a neural net model to process a paragraph each time and jointly build meaning representations for all DUs in the paragraph. The learned DU representations are used to predict a sequence of discourse relations in the paragraph, including both implicit and explicit relations. Although explicit relations are not our focus, predicting an explicit relation will help to reveal the pragmatic roles of its two DUs and reconstruct their representations, which will facilitate predicting neighboring implicit discourse relations that involve one of the DUs.\nIn addition, we introduce two novel designs to further improve discourse relation classification performance of our paragraph-level neural net model. First, previous work has indicated that recognizing explicit and implicit discourse relations requires different strategies, we therefore untie parameters in the discourse relation prediction layer of the neural networks and train two separate classifiers for predicting explicit and implicit discourse relations respectively. This unique design has improved both implicit and explicit discourse relation identification performance. Second, we add a CRF layer on top of the discourse relation prediction layer to fine-tune a sequence of predicted discourse relations by modeling discourse relation continuity and patterns in a paragraph.\nExperimental results show that the intuitive paragraph-level discourse relation prediction model achieves improved performance on PDTB for both implicit discourse relation classification and explicit discourse relation classification.\nHowever, most of existing approaches ignore wider paragraph-level contexts beyond the two discourse units that are examined for predicting a discourse relation in between.",

During this time she came to be called a \"Punk Mummy Warrior\" who guided her daughter, Ari Up's musical pursuits and supported the development of her band, The Slits, when Ari was just fourteen or fifteen. Forster hosted numerous musician house guests, and among them was Neneh Cherry, the teenage step-daughter of Don Cherry. Cherry performed backing vocal with The Slits for a time.\n\nDuring the 1960s and 70s, Forster was part of the bohemian scene in London. Starting in the late 1960s Forster's home in Shepherd's Bush became a crash pad, salon, and meeting place for rock musicians including Joe Strummer of The Clash, Jimi Hendrix, Jon Anderson of the band Yes, and many other bands.

The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell resulting in emission of discrete X-rays from the transitions. A common example is iodine-125 commonly used in medical settings.",

        "evidence": "Instead of training a scalar state-action estimator Q π (s, u), distributional RL represents an actionvalue as a random variable, denoted Z π (s, u). The distributional Bellman operator for policy evaluation in single-agent RL can then be expressed as follows:\nwhere S ∼ P (s |s, u), U ∼ π(u|s), and A D = B denotes the two random variables which follow the same probability distribution.\nIQN. Implicit Quantile Networks (IQN) is one of the widely-used single-agent distributional RL methods. IQN approximates the true action-value function using a quantile-based representation of the distributions. To be specific, each trained quantile represent a random variable Z(s, u, ω) which is a reparameterization of risk-level sample ω drawn from a uniform distribution U(0, 1). To train the IQN, one can use the following Huber quantile regression loss:\nwhere Z target is the target network whose parameters are updated periodically from the original action-value estimator Z. (s, u, r, s ) is a tuple of experience transitions from a replay buffer. In distributional RL, weights are used to express level of rewards and next state transitions are generated from the randomness of the environment.\nDistributional MARL. Recently, distributional RL has also been applied to the CTDE regime, but they lack the disentanglement of risk sources. RMIX and DFAC showed promising results by extending the agent-wise utility function from having deterministic variables to random variables. RMIX demonstrates the effectiveness of risk-sensitive MARL via distributional RL, but it is limited since it cannot represent policies which came from different risk sources (i.e., agent-wise risk-seeking yet environmentwise risk-averse policies). DFAC is another distributional MARL framework that uses mean-shape decomposition which separates the mean and variance parts of the utility functions to handle value function factorization. They propose DDN and DMIX as the DFAC variants of VDN and QMIX, respectively. DFAC extends IQN, a single-agent distributional RL algorithm, to learn the randomness of the environment. However, they do not consider the agent-wise risk that arises when learning networks with limited expressive power such as QMIX.

If, for any reason, a drill site is not accessible from the surface (ground level) then the drilling rig will be offset from the target. Because the drilling rig is not physically able to locate on top of the geological target the oil and gas company must use directional drilling techniques to steer the well to the target from an offset position. Examples of this could include drilling for resources under Federal land or when drilling in highly populated areas. Another reason for utilizing directional drilling techniques is to maximize hydrocarbon production. Directional drillers can turn the well-bore to intersect with the target zone at the X-Y axis, instead of only through the Z-axis. This maximizes the amount of \"zone\" the well-bore has access to.",

        "evidence": "The task assigned to annotators was to read sentences one at a time and label them with with binary labels indicating the polarity (i.e., positive/negative). Note that, the participants were not instructed to annotate whether a sentence is sarcastic or not., to rule out the Priming Effect (i.e., if sarcasm is expected beforehand, processing incongruity becomes relatively easier BIBREF12 ). The setup ensures its “ecological validity” in two ways: (1) Readers are not given any clue that they have to treat sarcasm with special attention. This is done by setting the task to polarity annotation (instead of sarcasm detection). (2) Sarcastic sentences are mixed with non sarcastic text, which does not give prior knowledge about whether the forthcoming text will be sarcastic or not.\nThe eye-tracking experiment is conducted by following the standard norms in eye-movement research BIBREF13 . At a time, one sentence is displayed to the reader along with the “aspect” with respect to which the annotation has to be provided. While reading, an SR-Research Eyelink-1000 eye-tracker (monocular remote mode, sampling rate 500Hz) records several eye-movement parameters like fixations (a long stay of gaze) and saccade (quick jumping of gaze between two positions of rest) and pupil size.\nThe accuracy of polarity annotation varies between 72%-91% for sarcastic texts and 75%-91% for non-sarcastic text, showing the inherent difficulty of sentiment annotation, when sarcasm is present in the text under consideration. Annotation errors may be attributed to: (a) lack of patience/attention while reading, (b) issues related to text comprehension, and (c) confusion/indecisiveness caused due to lack of context.\nFor our analysis, we do not discard the incorrect annotations present in the database. Since our system eventually aims to involve online readers for sarcasm detection, it will be hard to segregate readers who misinterpret the text. We make a rational assumption that, for a particular text, most of the readers, from a fairly large population, will be able to identify sarcasm. Under this assumption, the eye-movement parameters, averaged across all readers in our setting, may not be significantly distorted by a few readers who would have failed to identify sarcasm. This assumption is applicable for both regular and multi-instance based classifiers explained in section SECREF6 .\nNote that, the participants were not instructed to annotate whether a sentence is sarcastic or not., to rule out the Priming Effect (i.e., if sarcasm is expected beforehand, processing incongruity becomes relatively easier (Gibbs, 1986)).",

With these characteristics, the document clusters are 15 times larger than typical DUC clusters of ten documents and five times larger than the 25-document-clusters (Table TABREF26 ). In addition, the documents are also more variable in terms of length, as the (length-adjusted) standard deviation is twice as high as in the other corpora. With these properties, the corpus represents an interesting challenge towards real-world application scenarios, in which users typically have to deal with much more than ten documents.\nBecause we used a large web crawl as the source for our corpus, it contains documents from a variety of genres. To further analyze this property, we categorized a sample of 50 documents from the corpus.

Recent work by BIBREF8 considers a similar problem they call out-of-distribution detection. They use other datasets or classes excluded during training to form the out-of-distribution samples. This means that the out-of-scope samples are from a small set of coherent classes that differ substantially from the in-distribution samples. Similar experiments were conducted for evaluating unknown intent discovery models in BIBREF9. In contrast, our out-of-scope queries cover a broad range of phenomena and are similar in style and often similar in topic to in-scope queries, representing things a user might say given partial knowledge of the capabilities of a system.\nTable TABREF20 compares our dataset with other short-query intent classification datasets. The Snips BIBREF0 dataset and the dataset presented in BIBREF10 are the most similar to the in-scope part of our work, with the same type of conversational agent requests. Like our work, both of these datasets were bootstrapped using crowdsourcing. However, the Snips dataset has only a small number of intents and an enormous number of examples of each. Snips does present a low-data variation, with 70 training queries per intent, in which performance drops slightly. The dataset presented in BIBREF10 has a large number of intent classes, yet also contains a wide range of samples per intent class (ranging from 24 to 5,981 queries per intent, and so is not constrained in all cases).\nBIBREF11 created datasets with constrained training data, but with very few intents, presenting a very different type of challenge. We also include the TREC query classification datasets BIBREF7, which have a large set of labels, but they describe the desired response type (e.g., distance, city, abbreviation) rather than the action intents we consider. Moreover, TREC contains only questions and no commands. Crucially, none of the other datasets summarized in Table TABREF20 offer a feasible way to evaluate out-of-scope performance.\nThe Dialog State Tracking Challenge (DSTC) datasets are another related resource. Specifically, DSTC 1 BIBREF12, DSTC 2 BIBREF13, and DSTC 3 BIBREF14 contain “chatbot style\" queries, but the datasets are focused on state tracking. Moreover, most if not all queries in these datasets are in-scope. In contrast, the focus of our analysis is on both in- and out-of-scope queries that challenge a virtual assistant to determine whether it can provide an acceptable response.\nIn most other analyses and datasets, the idea of out-of-scope data is not considered, and instead the output classes are intended to cover all possible queries (e.g., TREC (Li and Roth, 2002)).",

        "question": "How was art used for manipulative purpose in racial discuss in the 20th century?",
        "evidence": "Racial categories have historically been used as a way to enable an oppressive figure or group to discriminate against other groups or individuals which were seen as different from that of the oppressor. In nineteenth and early twentieth century Europe, artwork was a common form of racialization which targeted countries in the Middle East and Asia. The artwork, predominantly paintings, were portrayed in order to instill prejudice in the Western populations through sexualizing and manipulating images. One of the most prominent examples of Orientalist work in art is a piece by Eugène Delacroix titled Women of Algiers in their Apartment. Dating back to 1834, it portrays three women resting in a harem in exotic clothing while an African woman is dressed in plain clothing, depicting her role as a servant. Fine textiles, hookahs, and other paraphernalia adorn the room, which represents a European fantasy of an exotic scene. Attempts to portray these cultures as strange, foreign and exotic through Orientalism led to intolerance towards the Arab and Asian communities in Europe and the United States. Others argue that Delacroix, who travelled in North Africa sketching extensively, was depicting a realistic scene of the era based on his first-hand knowledge and experience. In such an interpretation the clothing, for example, is consistent with the times, as Arab North Africans dressed differently from Europeans, and kept black slaves who would not have been treated as equals.",

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation. Section SECREF3 describes our test suite. The context-aware models we use in our experiments are detailed in Section SECREF4 .

        "evidence": "While ray marching in Eq. (1) allows computing the ray color, we are also interested in finding the distribution of distances that give rise to this color-this will allow using depths in RGB-D data for supervision. To this end, we show that Eq. (1) derives from an inhomogenous spatial Poisson process.\nConsider a ray r(t) = x 0 + dt traveling through a camera at position x 0 along direction d. The probability that light originating at point r(t) will not scatter and reach the camera unimpeded (transmittance) is equal to the probability that no events occur in the spatial Poisson process T (t) = exp (− t 0 σ(r(t ))dt ). NeRF does not model light sources explicitly, but assumes that lighting conditions are expressed by the color value of each point. As a result, the light emitted at the point r(t) in the direction of the camera −d has the color c(r(t), d), and its intensity is proportional to the density of particles σ(r(t)) at that point. Consequently, the amount of light reaching the camera from r(t) is proportional to\n(2)\nIn fact, under mild assumptions, p(t) is exactly equal to the distribution of possible depths t at which the observed colors originated 2 . We provide the full derivation in Appendix B.1.\nWe can now reframe Eq.

        "question": "Based on the reference text, provide a bulleted list of the contributing factors causing World War II.",
        "evidence": "World War II or the Second World War, often abbreviated as WWII or WW2, was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.\n\nWorld War II was by far the deadliest conflict in history; it resulted in an estimated 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massacres, and disease. In the wake of the Axis defeat, Germany and Japan were occupied, and war crimes tribunals were conducted against German and Japanese leaders.\n\nThe causes of World War II are debated, but contributing factors included the Second Italo-Ethiopian War, Spanish Civil War, Second Sino-Japanese War, Soviet–Japanese border conflicts, the rise of fascism in Europe, and European tensions in the aftermath of World War I. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland. The United Kingdom and France subsequently declared war on Germany on 3 September. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union had partitioned Poland and marked out their \"spheres of influence\" across Finland, Estonia, Latvia, Lithuania and Romania. From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, in a military alliance with Italy, Japan and other countries called the Axis. Following the onset of campaigns in North Africa and East Africa, and the fall of France in mid-1940, the war continued primarily between the European Axis powers and the British Empire, with war in the Balkans, the aerial Battle of Britain, the Blitz of the United Kingdom, and the Battle of the Atlantic. On 22 June 1941, Germany led the European Axis powers in an invasion of the Soviet Union, opening the Eastern Front, the largest land theatre of war in history.\n\nJapan, which aimed to dominate Asia and the Pacific, was at war with the Republic of China by 1937. In December 1941, Japan attacked American and British territories with near-simultaneous offensives against Southeast Asia and the Central Pacific, including an attack on the US fleet at Pearl Harbor which resulted in the United States and United Kingdom declaring war against Japan. The European Axis powers declared war on the United States in solidarity. Japan soon captured much of the western Pacific, but its advances were halted in 1942 after losing the critical Battle of Midway; later, Germany and Italy were defeated in North Africa and at Stalingrad in the Soviet Union. Key setbacks in 1943—including a series of German defeats on the Eastern Front, the Allied invasions of Sicily and the Italian mainland, and Allied offensives in the Pacific—cost the Axis powers their initiative and forced them into strategic retreat on all fronts. In 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained its territorial losses and pushed Germany and its allies back. During 1944 and 1945, Japan suffered reversals in mainland Asia, while the Allies crippled the Japanese Navy and captured key western Pacific islands.\n\nThe war in Europe concluded with the liberation of German-occupied territories and the invasion of Germany by the Western Allies and the Soviet Union, culminating in the Fall of Berlin to Soviet troops, Hitler's suicide, and the German unconditional surrender on 8 May 1945. Following the refusal of Japan to surrender on the terms of the Potsdam Declaration (issued 26 July 1945), the United States dropped the first atomic bombs on the Japanese cities of Hiroshima on 6 August and Nagasaki on 9 August. Faced with an imminent invasion of the Japanese archipelago, the possibility of additional atomic bombings, and the Soviet Union's declared entry into the war against Japan on the eve of invading Manchuria, Japan announced on 10 August its intention to surrender, signing a surrender document on 2 September 1945.\n\nWorld War II changed the political alignment and social structure of the globe and set the foundation for the international order of the world's nations during the Cold War and into present day. The United Nations was established to foster international co-operation and prevent future conflicts, with the victorious great powers—China, France, the Soviet Union, the United Kingdom, and the United States—becoming the permanent members of its Security Council. The Soviet Union and the United States emerged as rival superpowers, setting the stage for the nearly half-century-long Cold War. In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia. Most countries whose industries had been damaged moved towards economic recovery and expansion. Political and economic integration, especially in Europe, began as an effort to forestall future hostilities, end pre-war enmities, and forge a sense of common identity.",

Knock occurs when the timing of of the air and fuel mixture in the cylinder explodes too early and can cause serious damage to the engine components.

However, Anderson is praised for his basketball IQ. He is able to change speeds and fake out his opponents to keep them off balance. His methodical style earned him the nickname \"Slow Mo\" in eighth grade in AAU, and the name has stuck with him. \"[He] really understands how to use his speed—he's not super fast, but he's super bright and really knows how to use angles,\" said Kevin Boyle, who coached Anderson on the national team in 2012. USA Today described him as \"languid but quick enough to lead the fast break\". Anderson's defense was considered a weakness. In college, his teams usually played zone as he struggled containing smaller, quicker guards while playing man-to-man. His defense improved with the Spurs in 2017–18, when he guarded both forward positions while leveraging his wingspan and instincts. Against quicker small forwards, he uses his physicality to keep players off balance.",

The proposed method comprises an initialization and a gradient update stage.\nInitialization stage: We search for initialization values for LCCS to warm start the optimization process. We first compute the support BN statistics µ spt and σ spt by exponential moving average (EMA) for m epochs, which allows µ spt and σ spt to update smoothly. Then, we conduct a onedimensional grid search on the LCCS parameters by setting η spt,i = ρ spt,i = v for i ∈ {1, . . . , n} where v ∈ {0, 0.1, . . . , 1.0} and η s = ρ s = 1 − v with values tied across all BN layers. The initialization value that minimizes cross-entropy loss on the support samples is selected.\nWe further optimize the LCCS parameters by gradient descent update for m epochs while concurrently updating support BN statistics by EMA. In this stage, parameter values are not tied across BN layers and we do not impose convex constraint on the training and support coefficient pairs to allow more diverse combinations.\nWe set m = 10 for both stages for all our experiments.

The Republic was not supported by the Western powers due to the British-led policy of non-intervention. General Francisco Franco was sworn in as the supreme leader of the rebels on 1 October 1936. An uneasy relationship between the Republican government and the grassroots anarchists who had initiated a partial Social revolution also ensued.\n\n\nRepublican volunteers at Teruel, 1936\nThe civil war was viciously fought and there were many atrocities committed by all sides.

        "answer": "As the global approach suffers from the data sparsity issue of unseen words/entities, and the failure to induce underlying discriminative features for EL, neural network (NN) models with amazing feature abstraction and generalization ability are introduced to mitigate the limitation.",
        "evidence": " This work is licensed under a Creative Commons Attribution 4.0 International License. License details: http://creativecommons.org/licenses/by/4.0/\nEntity linking (EL), mapping entity mentions in texts to a given knowledge base (KB), serves as a fundamental role in many fields, such as question answering BIBREF0 , semantic search BIBREF1 , and information extraction BIBREF2 , BIBREF3 . However, this task is non-trivial because entity mentions are usually ambiguous. As shown in Figure FIGREF1 , the mention England refers to three entities in KB, and an entity linking system should be capable of identifying the correct entity as England cricket team rather than England and England national football team.\nEntity linking is typically broken down into two main phases: (i) candidate generation obtains a set of referent entities in KB for each mention, and (ii) named entity disambiguation selects the possible candidate entity by solving a ranking problem. The key challenge lies in the ranking model that computes the relevance between candidates and the corresponding mentions based on the information both in texts and KBs BIBREF4 . In terms of the features used for ranking, we classify existing EL models into two groups: local models to resolve mentions independently relying on textual context information from the surrounding words BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , and global (collective) models, which are the main focus of this paper, that encourage the target entities of all mentions in a document to be topically coherent BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 .\nGlobal models usually build an entity graph based on KBs to capture coherent entities for all identified mentions in a document, where the nodes are entities, and edges denote their relations. The graph provides highly discriminative semantic signals (e.g., entity relatedness) that are unavailable to local model BIBREF15 . For example (Figure FIGREF1 ), an EL model seemly cannot find sufficient disambiguation clues for the mention England from its surrounding words, unless it utilizes the coherence information of consistent topic “cricket\" among adjacent mentions England, Hussain, and Essex. Although the global model has achieved significant improvements, its limitation is threefold:\nTo mitigate the first limitation, recent EL studies introduce neural network (NN) models due to its amazing feature abstraction and generalization ability. In such models, words/entities are represented by low dimensional vectors in a continuous space, and features for mention as well as candidate entities are automatically learned from data BIBREF4 . However, existing NN-based methods for EL are either local models BIBREF16 , BIBREF17 or merely use word/entity embeddings for feature extraction and rely on another modules for collective disambiguation, which thus cannot fully utilize the power of NN models for collective EL BIBREF18 , BIBREF19 , BIBREF20 .\nThe second drawback of the global approach has been alleviated through approximate optimization techniques, such as PageRank/random walks BIBREF21 , graph pruning BIBREF22 , ranking SVMs BIBREF23 , or loopy belief propagation (LBP) BIBREF18 , BIBREF24 . However, these methods are not differentiable and thus difficult to be integrated into neural network models (the solution for the first limitation).\nTo overcome the third issue of inadequate training data, BIBREF17 has explored a massive amount of hyperlinks in Wikipedia, but these potential annotations for EL contain much noise, which may distract a naive disambiguation model BIBREF6 .\nIn this paper, we propose a novel Neural Collective Entity Linking model (NCEL), which performs global EL combining deep neural networks with Graph Convolutional Network (GCN) BIBREF25 , BIBREF26 that allows flexible encoding of entity graphs. It integrates both local contextual information and global interdependence of mentions in a document, and is efficiently trainable in an end-to-end fashion. Particularly, we introduce attention mechanism to robustly model local contextual information by selecting informative words and filtering out the noise. On the other hand, we apply GCNs to improve discriminative signals of candidate entities by exploiting the rich structure underlying the correct entities. To alleviate the global computations, we propose to convolute on the subgraph of adjacent mentions. Thus, the overall coherence shall be achieved in a chain-like way via a sliding window over the document. To the best of our knowledge, this is the first effort to develop a unified model for neural collective entity linking.\nIn experiments, we first verify the efficiency of NCEL via theoretically comparing its time complexity with other collective alternatives. Afterwards, we train our neural model using collected Wikipedia hyperlinks instead of dataset-specific annotations, and perform evaluations on five public available benchmarks. The results show that NCEL consistently outperforms various baselines with a favorable generalization ability. Finally, we further present the performance on a challenging dataset WW BIBREF19 as well as qualitative results, investigating the effectiveness of each key module.\nAlthough the global model has achieved significant improvements, its limitation is threefold: 1.The global approach suffers from the data sparsity issue of unseen words/entities, and the failure to induce underlying discriminative features for EL. 2.The joint inference mechanism in the global approach leads to expensive computations, especially when the entity graph may contain hundreds of nodes in case of long documents. 3.The annotated EL training data is usually expensive to obtain or only available in narrow domains, which results in possible overfitting issue or domain bias. To mitigate the first limitation, recent EL studies introduce neural network (NN) models due to its amazing feature abstraction and generalization ability.",

        "question": "List all the people mentioned in this paragraph on the history of Unix",
        "evidence": "The new operating system was initially without organizational backing, and also without a name. At this stage, the new operating system was a singletasking operating system, not a multitasking one such as Multics. The name Unics (Uniplexed Information and Computing Service, pronounced as \"eunuchs\"), a pun on Multics (Multiplexed Information and Computer Services), was initially suggested for the project in 1970. Brian Kernighan claims the coining for himself, and adds that \"no one can remember\" who came up with the final spelling Unix. Dennis Ritchie and Doug McIlroy also credit Kernighan.\n\nWhen the Computing Sciences Research Center wanted to use Unix on a machine larger than the PDP-7, while another department needed a word processor, Thompson and Ritchie added text processing capabilities to Unix and received funding for a PDP-11. For the first time in 1970, the Unix operating system was officially named and ran on the PDP-11. A text-formatting program called roff and a text editor were added. All three were written in PDP-11 assembly language. Bell Labs used this initial text-processing system, consisting of Unix, roff, and the editor, for text processing of patent applications. Roff soon evolved into troff, the first electronic publishing program with full typesetting capability.\n\nAs the system grew in complexity and the research team wanted more users, the need for a manual grew apparent. The UNIX Programmer's Manual was published on 3 November 1971; commands were documented in the \"man page\" format that is still used, offering terse reference information about usage as well as bugs in the software, and listing the authors of programs to channel questions to them.\n\nAfter other Bell Labs departments purchased DEC PDP-11s, they also chose to run Unix instead of DEC's own operating system. By Version 4 it was widely used within the laboratory and a Unix Support Group was formed, helping the operating system survive by formalizing its distribution.\n\nIn 1973, Version 4 Unix was rewritten in the higher-level language C, contrary to the general notion at the time that an operating system's complexity and sophistication required it to be written in assembly language. The C language appeared as part of Version 2. Thompson and Ritchie were so influential on early Unix that McIlroy estimated that they wrote and debugged about 100,000 lines of code that year, stating that \"[their names] may safely be assumed to be attached to almost everything not otherwise attributed\". Although assembly did not disappear from the man pages until Version 8, the migration to C suggested portability of the software, requiring only a relatively small amount of machine-dependent code to be replaced when porting Unix to other computing platforms. Version 4 Unix, however, still had considerable PDP-11-dependent code and was not suitable for porting. The first port to other platform was made five years later (1978) for Interdata 8/32.\n\nThe Unix operating system was first presented formally to the outside world at the 1973 Symposium on Operating Systems Principles, where Ritchie and Thompson delivered a paper. This led to requests for the system, but under a 1956 consent decree in settlement of an antitrust case, the Bell System (the parent organization of Bell Labs) was forbidden from entering any business other than \"common carrier communications services\", and was required to license any patents it had upon request. Unix could not, therefore, be turned into a product. Bell Labs instead shipped the system for the cost of media and shipping. Ken Thompson quietly began answering requests by shipping out tapes and disks, each accompanied by – according to legend – a note signed, \"Love, Ken\".",

I shall wait in the west and the fox can wait in the east and ensure the prey do not escape to the east or west.\n \nGood idea. so they all followed the plan. Along came a rabbit, ran helter skelter frightened  on seeing the fox and the wolf and straight into the lion, who with one swipe of its paw killed the rabbit. Next a donkey came by and met a similar fate. So did a deer. The lion felt they had sufficient food for their meal and asked the wolf of how we were going to share the meal. The wolf said that the fox can have the rabbit., the lion can have the donkey and he would partake of the deer. The lion knew the tastiest meat is that of the deer, and sensing the deviousness of the advisor wolf smacked him dead. Next he asked the fox for advice on sharing. The fox meekly replied that whatever way the lion wants to have the meal is fine and good. On hearing this the lion said you are a wise and good advisor, who is your guru? The fox humbly replied that the wolf was his guru.  Seeing the fate of the wolf the fox learnt from the wolf's mistake.\n \nThe moral of the story: You can and must learn from your mistakes.

        "evidence": "Visual Question Answering (VQA) refers to a challenging task which lies at the intersection of image understanding and language processing. The VQA task has witnessed a significant progress in the recent years by the machine intelligence community. The aim of VQA is to develop a system to answer specific questions about an input image. The answer could be in any of the following forms: a word, a phrase, binary answer, multiple choice answer, or a fill in the blank answer. Agarwal et al. BIBREF0 presented a novel way of combining computer vision and natural language processing concepts of to achieve Visual Grounded Dialogue, a system mimicking the human understanding of the environment with the use of visual observation and language understanding.\nThe advancements in the field of deep learning have certainly helped to develop systems for the task of Image Question Answering. Krizhevsky et al BIBREF1 proposed the AlexNet model, which created a revolution in the computer vision domain. The paper introduced the concept of Convolution Neural Networks (CNN) to the mainstream computer vision application. Later many authors have worked on CNN, which has resulted in robust, deep learning models like VGGNet BIBREF2, Inception BIBREF3, ResNet BIBREF4, and etc. Similarly, the recent advancements in natural language processing area based on deep learning have improved the text understanding prforance as well. The first major algorithm in the context of text processing is considered to be the Recurrent Neural Networks (RNN) BIBREF5 which introduced the concept of prior context for time series based data. This architecture helped the growth of machine text understanding which gave new boundaries to machine translation, text classification and contextual understanding. Another major breakthrough in the domain was the introduction of Long-Short Term Memory (LSTM) architecture BIBREF6 which improvised over the RNN by introducing a context cell which stores the prior relevant information.\nThe vanilla VQA model BIBREF0 used a combination of VGGNet BIBREF2 and LSTM BIBREF6. This model has been revised over the years, employing newer architectures and mathematical formulations. Along with this, many authors have worked on producing datasets for eliminating bias, strengthening the performance of the model by robust question-answer pairs which try to cover the various types of questions, testing the visual and language understanding of the system. In this survey, first we cover major datasets published for validating the Visual Question Answering task, such as VQA dataset BIBREF0, DAQUAR BIBREF7, Visual7W BIBREF8 and most recent datasets up to 2019 include Tally-QA BIBREF9 and KVQA BIBREF10.

        "evidence": "Machine reading comprehension and question answering has becomes a crucial application problem in evaluating the progress of AI system in the realm of natural language processing and understanding BIBREF0 . The computational linguistics communities have devoted significant attention to the general problem of machine reading comprehension and question answering.\nHowever, most of existing reading comprehension tasks only focus on shallow QA tasks that can be tackled very effectively by existing retrieval-based techniques BIBREF1 . For example, recently we have seen increased interest in constructing extractive machine reading comprehension datasets such as SQuAD BIBREF2 and NewsQA BIBREF3 . Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively.

        "answer": "Despite a rich cricket tradition in New Zealand, the country only became a test playing nation during the season of 1929/30, when the MCC toured the country playing 4 tests. Australia, the nearest test playing country to New Zealand, refused to grant Test status to any games played between the two nations until well after World War 2. This lack of test opportunities led to a now common path of talented New Zealanders moving off shore for the chance to play test cricket- most notably in the pre WWII period of Clarrie Grimmet, who took over 200 test wickets playing for Australia. Since then, Andrew Caddick (234 test wickets at an average of 29.91) and Ben Stokes (5000+ test runs and 196 test wickets) have played leading roles for England in tests.\n\nIf however we define the question as \"the best test cricket player to have played for New Zealand\", then there are perhaps only 3 or 4 candidates that feature. Of the current generation, there is no doubt that Kane Williamson will one day be regarded as the greatest player to have come from New Zealand- with over 8000 test runs at an average north of 50. With many years in front of him, Williamson will no doubt hold the crown of best test cricketer in years to come. \n\nMartin Crowe must likewise be regarded in the pantheon of test greats to have played for New Zealand- despite a slow start to his career, and injuries curtailing his time in the team, he amassed over 5000 runs at an average of over 45.\n\nHowever, most will agree that the most influential cricketer ever to play test cricket for New Zealand was Sir Richard Hadlee- the first cricketer to be knighted whilst still playing cricket for his country. Hadlee's bowling average of 22.29 is one of best in test cricket history, and at the time of his retirement he held the record for test wickets, at 431. Gaining 5 wickets in an innings 36 times was also a record, and led New Zealand to some of it's most famous test victories, notably victory in a series in Australia for the first time in 1985/86, with his best test figures of 15 for 123 coming in the first test at the Gabba. Added to his bowling, his destructive lower order batting made his one of the preeminent all rounders of the game., and truly NZ's best test cricketer.",

Long-range predictions to 2150 range from a population decline to 3.2 billion in the \"low scenario\", to \"high scenarios\" of 24.8 billion.

        "evidence": "",
        "answer": "Two broad categories of merchant ships would likely be most useful in a modern naval conflict: large roll-on/roll-off ships with double hulls and small, fast ferries. If an adversary can find a ship on the open ocean and target it with a modern anti-ship missile, this opponent can certainly destroy the complex machinery needed to operate a container port or an oil terminal. Consequently, any cargo you want to unload in a war zone is going to need to drive off a ship on the back of a truck....quickly. An oil tanker will be useless, but a RO/RO ship loaded with tanker trucks can unload lots of fuel under austere/wartime conditions. Similarly, a container ship will be of little use without the large, land-based cranes used at most container shipping ports. A ferry loaded with trucks hauling shipping containers can quickly load and unload without the need for specialized equipment. Data from the Iran-Iraq war suggest that a large, 50,000+ ton RO/RO with a double hull is likely big enough to survive a hit from a modern anti-ship missile. A fast ferry that can move at ~40 knots is probably going to be too small to detect from space or shore using backscatter radar. Conversely, a 100,000-ton PanMax oil tanker or a 5,000 TEU container ship will be easy to detect, and slow enough to target.",

Second, standard text-based processing techniques are applied to the resulting tokenizations, and produce a vector representation for each spoken document, typically a bag-of-words multinomial representation, or a more compact vector given by probabilistic topic models BIBREF2 , BIBREF3 . Finally, topic ID is performed on the spoken document representations by supervised training of classifiers, such as Bayesian classifiers and support vector machines (SVMs).\nHowever, in the first step, training the ASR system required for tokenization itself requires transcribed speech and pronunciations. In this paper, we focus on a difficult and realistic scenario where the speech corpus of a test language is annotated only with a minimal number of topic labels, i.e., no manual transcriptions or dictionaries for building an ASR system are available. We aim to exploit approaches that enable topic ID on speech without any knowledge of that language other than the topic annotations.\nIn this scenario, while previous work demonstrates that the cross-lingual phoneme recognizers can produce reasonable speech tokenizations BIBREF4 , BIBREF5 , the performance is highly dependent on the language and environmental condition (channel, noise, etc.) mismatch between the training and test data. Therefore, we focus on unsupervised approaches that operate directly on the speech of interest. Raw acoustic feature-based unsupervised term discovery (UTD) is one such approach that aims to identify and cluster repeating word-like units across speech based around segmental dynamic time warping (DTW) BIBREF6 , BIBREF7 . BIBREF8 shows that using the word-like units from UTD for spoken document classification can work well; however, the results in BIBREF8 are limited since the acoustic features on which UTD is performed are produced by acoustic models trained from the transcribed speech of its evaluation corpus. In this paper, we investigate UTD-based topic ID performance when UTD operates on language-independent speech representations extracted from multilingual bottleneck networks trained on languages other than the test language BIBREF9 . Another alternative to producing speech tokenizations without language dependency is the model-based approach, i.e., unsupervised learning of hidden Markov model (HMM) based phoneme-like units from untranscribed speech. We exploit the Variational Bayesian inference based acoustic unit discovery (AUD) framework in BIBREF10 that allows parallelized large-scale training. In topic ID tasks, such AUD-based systems have been shown to outperform other systems based on cross-lingual phoneme recognizers BIBREF5 , and this paper aims to further investigate how the performance compares among UTD, AUD and ASR based systems.\nMoreover, after the speech is tokenized, these works BIBREF0 , BIBREF1 , BIBREF4 , BIBREF5 , BIBREF8 , BIBREF9 are limited to using bag-of-words features as spoken document representations. While UTD only identifies relatively long (0.5 – 1 sec) repeated terms, AUD/ASR enables full-coverage segmentation of continuous speech into a sequence of units/words, and such a resulting temporal sequence enables another feature learning architecture based on convolutional neural networks (CNNs) BIBREF11 ; instead of treating the sequential tokens as a bag of acoustic units or words, the whole token sequence is encoded as concatenated continuous vectors, and followed by convolution and temporal pooling operations that capture the local and global dependencies. Such continuous space feature extraction frameworks have been used in various language processing tasks like spoken language understanding BIBREF12 , BIBREF13 and text classification BIBREF14 , BIBREF15 . However, three questions are worth investigating in our AUD-based setting: (i) if such a CNN-based framework can perform as well on noisy automatically discovered phoneme-like units as on orthographic words/characters, (ii) if pre-trained vectors of phoneme-like units from word2vec BIBREF16 provide superior performance to random initialization as evidenced by the word-based tasks, and (iii) if CNNs are still competitive in low-resource settings of hundreds to two-thousand training exemplars, rather than the large/medium sized datasets as in previous work BIBREF14 , BIBREF15 .\nFinally, incorporating the different tokenization and feature representation approaches noted above, we perform comprehensive topic ID evaluations on both single-label and multi-label spoken document classification tasks.\n\nTopic identification (topic ID) on speech aims to identify the topic(s) for given speech recordings, referred to as spoken documents, where the topics are a predefined set of classes or labels. This task is typically formulated as a three-step process. First, speech is tokenized into words or phones by automatic speech recognition (ASR) systems [1], or by limited-vocabulary keyword spotting [2]. Second, standard text-based processing techniques are applied to the resulting tokenizations, and produce a vector representation for each spoken document, typically a bag-of-words multinomial representation, or a more compact vector given by probabilistic topic models [3, 4]. Finally, topic ID is performed on the spoken document representations by supervised training of classifiers, such as Bayesian classifiers and support vector machines (SVMs).",

We first experimented with a smaller Jasper5x3 model to pick the top 3 settings before training on larger Jasper models. We found that layer norm with GAU performed the best on the smaller model. Layer norm with ReLU and batch norm with ReLU came second and third in our tests. Using these 3, we conducted further experiments on a larger Jasper10x4. For larger models, we noticed that batch norm with ReLU outperformed other choices. Thus, leading us to decide on batch normalization and ReLU for our architecture.\nDuring batching, all sequences are padded to match the longest sequence. These padded values caused issues when using layer norm. We applied a sequence mask to exclude padding values from the mean and variance calculation. Further, we computed mean and variance over both the time dimension and channels similar to the sequence-wise normalization proposed by Laurent et al. BIBREF19 . In addition to masking layer norm, we additionally applied masking prior to the convolution operation, and masking the mean and variance calculation in batch norm. These results are shown in Table TABREF16 . Interestingly, we found that while masking before convolution gives a lower WER, using masks for both convolutions and batch norm results in worse performance.\nAs a final note, we found that training with weight norm was very unstable leading to exploding activations.\nAll experiment results are shown in Table 2.

In these languages, the words in a sentence are marked with morphological endings that reflect the grammatical gender of the surrounding nouns. This means that if the gender of one word changes, the others have to be updated to match. As a result, simple heuristics, such as augmenting a corpus with additional sentences in which he and she have been swapped BIBREF9 , will yield ungrammatical sentences. Consider the Spanish phrase el ingeniero experto (the skilled engineer).

The immediacy of their consent has been viewed as an example of divine power, although this is not stated in the text. Another explanation is that some of the disciples may have heard of Jesus beforehand, as implied by the Gospel of John, which states that Andrew was a disciple of John the Baptist, and that he and his brother started following Jesus as soon as Jesus had been baptized.\n\nMatthew describes Jesus meeting James and John, also fishermen and brothers, very shortly after recruiting Simon and Andrew. Matthew and Mark identify James and John as sons of Zebedee. Luke adds to Matthew and Mark that James and John worked as a team with Simon and Andrew. Matthew states that at the time of the encounter, James and John were repairing their nets, but readily joined Jesus without hesitation.\n\nThis parallels the accounts of Mark and Luke, but Matthew implies that the men have also abandoned their father (since he is present in the boat they abandon behind them), and Carter feels this should be interpreted to mean that Matthew's view of Jesus is one of a figure rejecting the traditional patriarchal structure of society, where the father had command over his children; most scholars, however, just interpret it to mean that Matthew intended these two to be seen as even more devoted than the other pair, or that Jesus expected the imminent coming of the kingdom.\n\nThe Synoptic Gospels go on to describe that later in Jesus' ministry he noticed a tax collector in his booth. The tax collector, called Matthew in Matthew 9:9, and Levi in Mark 2:14 and Luke 5:27, is asked by Jesus to become one of his disciples. Matthew/Levi is stated to have accepted and then invited Jesus for a meal with his friends. Tax collectors were seen as villains in Jewish society, and the Pharisees are described as asking Jesus why he is having a meal with such disreputable people.

Then come three versions of the ClaimBuster system: CB-Platform uses scores from the online demo, which we accessed on December 20, 2016, and SVM$_{CBfeat}$ and FNN$_{CBfeat}$ are our re-implementations, trained on our dataset.\nWe can see that all systems perform well above the random baseline. The three versions of ClaimBuster also outperform the TF.IDF baseline on most measures. Moreover, our reimplementation of ClaimBuster performs better than the online platform in terms of MAP. This is expected as their system is trained on a different dataset and it may suffer from testing on slightly out-of-domain data. At the same time, this is reassuring for our implementation of the features, and allows for a more realistic comparison to the ClaimBuster system.\nMore importantly, both the SVM and the FNN versions of our system consistently outperform all three versions of ClaimBuster on all measures. This means that the extra information coded in our model, mainly more linguistic, structural, and contextual features, has an important contribution to the overall performance.\nWe can further see that the neural network model, FNN$_{All}$, clearly outperforms the SVM model: consistently on all measures.

The loss in performance is much higher when comments are missing, indicating that the comments contain the most important information about stance. As can be expected, the score achieved without comments is only slightly different from the target-wise majority class baseline.\nBut there is also a loss in performance when the questions are missing, which underlines the importance of pairing both pieces of text. The effect of missing questions is especially strong in the supervised and cross-lingual settings. To illustrate this, we provide in Table TABREF48 some examples of comments that occur with multiple different targets in the training set. Those examples can explain why the target can be essential for disambiguating a stance detection problem. On the other hand, the effect of omitting the questions is less pronounced in the cross-target settings.\nThe above single-segment experiments tell us that both the comment and the question provide crucial information. But it is possible that the M-Bert model, even though trained on both segments, mainly looks at a single segment at test time. To rule this out, we probe the model with randomized data at test time:\nTest the model on versions of the test sets where the comments remain in place but the questions are shuffled randomly (random questions). We make sure that the random questions come from the same test set and language as the original questions.\nKeep the questions in place and randomize the comments (random comments). Again we shuffle the comments only within test set boundaries.\nThe results in Table TABREF39 show that the performance of the model decreases in both cases, confirming that it learns to take into account both segments.\nIn order to rule out that only the questions or only the comments are necessary to optimally solve the task, we conduct some additional experiments: • Only use a single segment containing the comment, removing the questions from the training and test data (missing questions). • Only use the question and remove the comment (missing comments).",

        "answer": "When people talk about \"lifting\" their trucks, they are referring to increasing the height and ground clearance through modification to the suspension of the vehicle.  Most often this is in reference to pick-up trucks, as those vehicles come from the manufacturer with the front of the vehicle at a lower height than the rear.  Know as a \"rake\", this is intended to allow the vehicle to ride at a level height even when carrying significant weight in the truck bed or towing heavy trailers.  There are various methods for lifting a vehicle that range from inexpensive spacers to elevate factory springs to more comprehensive systems replacing multiple suspension elements with new, purpose-built components.

        "question": "Using this definition, can you summarize why hyperventilation is considered dangerous?",
        "evidence": "Voluntary hyperventilation before beginning voluntary apnea is commonly believed to allow the person involved to safely hold their breath for a longer period. In reality, it will give the impression that one does not need to breathe, while the body is actually experiencing a blood-oxygen level that would normally, and indirectly, invoke a strong dyspnea and eventually involuntary breathing. Some have incorrectly attributed the effect of hyperventilation to increased oxygen in the blood, not realizing that it is actually due to a decrease in CO2 in the blood and lungs. Blood leaving the lungs is normally fully saturated with oxygen, so hyperventilation of normal air cannot increase the amount of oxygen available, as oxygen in blood is the direct factor. Lowering the CO2 concentration increases the pH of the blood, thus increasing the time before blood becomes acidic enough so the respiratory center becomes stimulated, as described above. \nThe primary urge to breathe is triggered by rising carbon dioxide (CO2) levels in the bloodstream. Carbon dioxide builds up in the bloodstream when oxygen is metabolized and it needs to be expelled as a waste product. The body detects carbon dioxide levels very accurately and relies on this as the primary trigger to control breathing. Hyperventilation artificially depletes the resting concentration of carbon dioxide causing a low blood carbon dioxide condition called hypocapnia. Hypocapnia reduces the reflexive respiratory drive, allowing the delay of breathing and leaving the diver susceptible to loss of consciousness from hypoxia. For most healthy people, the first sign of low oxygen levels is a greyout or unconsciousness: there is no bodily sensation that warns a diver of an impending blackout.\nIf a person loses consciousness underwater, there is considerable danger that they will drown. An alert diving partner or nearby lifeguard would be in the best position to rescue such a person. Static apnea blackout occurs at the surface when a motionless diver holds their breath long enough for the circulating oxygen in blood to fall below that required for the brain to maintain consciousness. It involves no pressure changes in the body and is usually performed to enhance breath-hold time. It should never be practiced alone, but under strict safety protocols with a safety guard or equipment beside the diver.",
        "answer": "Hyperventilation does not increase the amount of oxygen available but artificially decreases carbon dioxide (CO2) levels in blood and lungs. \nBecause the primary urge to breathe is triggered by rising carbon dioxide levels, it gives false impression that one does not need to breath.

        "evidence": "In this work, we introduced a model for forecasting conversational events that processes comments as they happen and takes the full conversational context into account to make an updated prediction at each step. This model fills a void in the existing literature on conversational forecasting, simultaneously addressing the dual challenges of capturing inter-comment dynamics and dealing with an unknown horizon. We find that our model achieves state-of-the-art performance on the task of forecasting derailment in two different datasets that we release publicly. We further show that the resulting system can provide substantial prior notice of derailment, opening up the potential for preemptive interventions by human moderators BIBREF65.\nWhile we have focused specifically on the task of forecasting derailment, we view this work as a step towards a more general model for real-time forecasting of other types of emergent properties of conversations. Follow-up work could adapt the CRAFT architecture to address other forecasting tasks mentioned in Section SECREF2—including those for which the outcome is extraneous to the conversation. We expect different tasks to be informed by different types of inter-comment dynamics, and further architecture extensions could add additional supervised fine-tuning in order to direct it to focus on specific dynamics that might be relevant to the task (e.g., exchange of ideas between interlocutors or stonewalling).\nWith respect to forecasting derailment, there remain open questions regarding what human moderators actually desire from an early-warning system, which would affect the design of a practical system based on this work. For instance, how early does a warning need to be in order for moderators to find it useful? What is the optimal balance between precision, recall, and false positive rate at which such a system is truly improving moderator productivity rather than wasting their time through false positives? What are the ethical implications of such a system? Follow-up work could run a user study of a prototype system with actual moderators to address these questions.\nA practical limitation of the current analysis is that it relies on balanced datasets, while derailment is a relatively rare event for which a more restrictive trigger threshold would be appropriate. While our analysis of the precision-recall curve suggests the system is robust across multiple thresholds ($AUPR=0.7$), additional work is needed to establish whether the recall tradeoff would be acceptable in practice.\nFinally, one major limitation of the present work is that it assigns a single label to each conversation: does it derail or not? In reality, derailment need not spell the end of a conversation; it is possible that a conversation could get back on track, suffer a repeat occurrence of antisocial behavior, or any number of other trajectories. It would be exciting to consider finer-grained forecasting of conversational trajectories, accounting for the natural—and sometimes chaotic—ebb-and-flow of human interactions.\n\nAcknowledgements.

The encoding task is divided across several collaborating agents, each is responsible for a subsection of text through a multi-layer LSTM with word attention. Their model seems however overly complicated when it comes to the extractive summarization task, where word attention is arguably much less critical. So, we do not consider this model further in this paper.\ndiscourselongdocument also propose a model for abstractive summarization taking the structure of documents into consideration with a hierarchical approach, and test it on longer documents with section information, i.e. scientific papers. In particular, they apply a hierarchical encoder at the word and section levels. Then, in the decoding step, they combine the word attention and section attention to obtain a context vector.\nThis approach to capture discourse structure is however quite limited both in general and especially when you consider its application to extractive summarization. First, their hierarchical method has a large number of parameters and it is therefore slow to train and likely prone to overfitting. Secondly, it does not take the global context of the whole document into account, which may arguably be critical in extractive methods, when deciding on the salience of a sentence (or even a word). The extractive summarizer we present in this paper tries to address these limitations by adopting the parameter lean LSTM-minus method, and by explicitly modeling the global context.\nThe extractive summarizer we present in this paper tries to address these limitations by adopting the parameter lean LSTM-minus method, and by explicitly modeling the global context.",

Similar observation has also been reported by BIBREF31 ( BIBREF31 ) for the task of sentiment analysis. The task of topic spotting is arguably more challenging than document classification. In the topic spotting task, the number of output classes (66/42 classes) is much more than those in document classification (5/6 classes), which is done mainly on the texts from customer reviews. Dialogues in SWBD have on an average 200 utterances and are much longer texts than customer reviews.

However, some more traditionally based composers such as Dmitri Shostakovich and Benjamin Britten maintained a tonal style of composition despite the prominent serialist movement.\n\nIn America, composers like Milton Babbitt, John Cage, Elliott Carter, Henry Cowell, Philip Glass, Steve Reich, George Rochberg, and Roger Sessions, formed their own ideas. Some of these composers (Cage, Cowell, Glass, Reich) represented a new methodology of experimental music, which began to question fundamental notions of music such as notation, performance, duration, and repetition, while others (Babbitt, Rochberg, Sessions) fashioned their own extensions of the twelve-tone serialism of Schoenberg.",

        "question": "When do the authors find that this approach outperforms a more conventional machine translation criterion?",
        "answer": "Both when attempting to interoperate with neuralese speakers and when predicting their state.",
        "evidence": "Several recent papers have described approaches for learning deep communicating policies (DCPs): decentralized representations of behavior that enable multiple agents to communicate via a differentiable channel that can be formulated as a recurrent neural network. DCPs have been shown to solve a variety of coordination problems, including reference games BIBREF0 , logic puzzles BIBREF1 , and simple control BIBREF2 . Appealingly, the agents' communication protocol can be learned via direct backpropagation through the communication channel, avoiding many of the challenging inference problems associated with learning in classical decentralized decision processes BIBREF3 .\nBut analysis of the strategies induced by DCPs has remained a challenge. As an example, fig:teaser depicts a driving game in which two cars, which are unable to see each other, must both cross an intersection without colliding. In order to ensure success, it is clear that the cars must communicate with each other. But a number of successful communication strategies are possible—for example, they might report their exact $(x, y)$ coordinates at every timestep, or they might simply announce whenever they are entering and leaving the intersection. If these messages were communicated in natural language, it would be straightforward to determine which strategy was being employed. However, DCP agents instead communicate with an automatically induced protocol of unstructured, real-valued recurrent state vectors—an artificial language we might call “neuralese,” which superficially bears little resemblance to natural language, and thus frustrates attempts at direct interpretation.\nWe propose to understand neuralese messages by translating them. In this work, we present a simple technique for inducing a dictionary that maps between neuralese message vectors and short natural language strings, given only examples of DCP agents interacting with other agents, and humans interacting with other humans. Natural language already provides a rich set of tools for describing beliefs, observations, and plans—our thesis is that these tools provide a useful complement to the visualization and ablation techniques used in previous work on understanding complex models BIBREF4 , BIBREF5 .\nWhile structurally quite similar to the task of machine translation between pairs of human languages, interpretation of neuralese poses a number of novel challenges. First, there is no natural source of parallel data: there are no bilingual “speakers” of both neuralese and natural language. Second, there may not be a direct correspondence between the strategy employed by humans and DCP agents: even if it were constrained to communicate using natural language, an automated agent might choose to produce a different message from humans in a given state. We tackle both of these challenges by appealing to the grounding of messages in gameplay. Our approach is based on one of the core insights in natural language semantics: messages (whether in neuralese or natural language) have similar meanings when they induce similar beliefs about the state of the world.\nBased on this intuition, we introduce a translation criterion that matches neuralese messages with natural language strings by minimizing statistical distance in a common representation space of distributions over speaker states. We explore several related questions:\nOur translation model and analysis are general, and in fact apply equally to human–computer and human–human translation problems grounded in gameplay. In this paper, we focus our experiments specifically on the problem of interpreting communication in deep policies, and apply our approach to the driving game in fig:teaser and two reference games of the kind shown in fig:bird-examples. We find that this approach outperforms a more conventional machine translation criterion both when attempting to interoperate with neuralese speakers and when predicting their state.\nWe find that this approach outperforms a more conventional machine translation criterion both when attempting to interoperate with neuralese speakers and when predicting their state.",

It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change, and information systems including the transmission of information in telecommunication.\n\nThe thermodynamic concept was referred to by Scottish scientist and engineer William Rankine in 1850 with the names thermodynamic function and heat-potential. In 1865, German physicist Rudolf Clausius, one of the leading founders of the field of thermodynamics, defined it as the quotient of an infinitesimal amount of heat to the instantaneous temperature. He initially described it as transformation-content, in German Verwandlungsinhalt, and later coined the term entropy from a Greek word for transformation. Referring to microscopic constitution and structure, in 1862, Clausius interpreted the concept as meaning disgregation.\n\nA consequence of entropy is that certain processes are irreversible or impossible, aside from the requirement of not violating the conservation of energy, the latter being expressed in the first law of thermodynamics. Entropy is central to the second law of thermodynamics, which states that the entropy of isolated systems left to spontaneous evolution cannot decrease with time, as they always arrive at a state of thermodynamic equilibrium, where the entropy is highest.\n\nAustrian physicist Ludwig Boltzmann explained entropy as the measure of the number of possible microscopic arrangements or states of individual atoms and molecules of a system that comply with the macroscopic condition of the system. He thereby introduced the concept of statistical disorder and probability distributions into a new field of thermodynamics, called statistical mechanics, and found the link between the microscopic interactions, which fluctuate about an average configuration, to the macroscopically observable behavior, in form of a simple logarithmic law, with a proportionality constant, the Boltzmann constant, that has become one of the defining universal constants for the modern International System of Units (SI).\n\nIn 1948, Bell Labs scientist Claude Shannon developed similar statistical concepts of measuring microscopic uncertainty and multiplicity to the problem of random losses of information in telecommunication signals. Upon John von Neumann's suggestion, Shannon named this entity of missing information in analogous manner to its use in statistical mechanics as entropy, and gave birth to the field of information theory. This description has been identified as a universal definition of the concept of entropy.",

        "question": "What is their approach based on?",
        "answer": "Unsupervised question-answering.",
        "evidence": "Every day textual information is being added/updated on Wikipedia, as well as other social media platforms like Facebook, Twitter, etc. These platforms receive a huge amount of unverified textual data from all its users such as News Channels, Bloggers, Journalists, Field-Experts which ought to be verified before other users start consuming it. This information boom has increased the demand of information verification also known as Fact Checking. Apart from the encyclopedia and other platforms, domains like scientific publications and e-commerce also require information verification for reliability purposes. Generally, Wikipedia authors, bloggers, journalists and scientists provide references to support their claims. Providing referenced text against the claims makes the fact checking task a little easier as the verification system no longer needs to search for the relevant documents.\nWikipedia manages to verify all this new information with a number of human reviewers. Manual review processes introduce delays in publishing and is not a well scalable approach. To address this issue, researchers have launched relevant challenges, such as the Fake News Challenge (BIBREF0), Fact Extraction and VERification (FEVER) (BIBREF1) challenge along with the datasets. Moreover, Thorne and Vlachos (BIBREF2) released a survey on the current models for automated fact-checking. FEVER is the largest dataset and contains around 185k claims from the corpus of 5.4M Wikipedia articles. The claims are labeled as “SUPPORTS”, “REFUTES”, or “NOT ENOUGH INFO”, based on the evidence set.\nIn this paper, we propose an unsupervised question-answering based approach for solving the fact-checking problem. This approach is inspired from the memory-based reading comprehension task that humans perform at an early age. As we know that kids in schools, first read and learn the syllabus content so that they can answer the questions in the exam. Similarly, our model learns a language model and linguistics features in unsupervised fashion from the provided Wikipedia pages.\nTo transform the FEVER dataset into the above-mentioned task, we first generate the questions from the claims. In literature, there are majorly two types of Question Generation systems: Rule-based and Neural Question Generation (NQG) model based. Ali et al. (BIBREF3) proposed a rule-based pipeline to automate the question generation using POS (Part-of-speech) tagging and Named Entity Recognition (NER) tagging from the sentences. Recently, many NQG models have been introduced to generate questions in natural language. Serban et al. (BIBREF4) achieved better performance for question generation utilizing (passage, question, answer) triplets as training data and an encoder-decoder based architecture as their learning model.\nDu et al. (BIBREF5) introduced a sequence-to-sequence model with an attention mechanism, outperforming rule-base question generation systems. Although the models proposed in (BIBREF6; BIBREF7) are effective, they require a passage to generate the plausible questions which is not readily available in the FEVER dataset. To resolve the issues and to keep the system simple but effective, we chose to generate questions similar to a Cloze-task or masked language modeling task. Such a task makes the problem more tractable as the masked entities are already known (i.e. named entities) and tight as there is only one correct answer for a given question. Later when the answers are generated, due to the question generation process, it becomes very easy to identify the correct answers.\nWe use the BERT's (Bidirectional Encoder Representations from Transformers) (BIBREF8) masked language model, that is pre-trained on Wikipedia articles for predicting the masked entities. Currently, neither the claim verification process nor the question generation process mandates explicit reasoning. For the same reason, it is difficult to put “REFUTES” or “NOT ENOUGH INFO” labels. To resolve this issue, we classify the unsupported claims as “MANUAL_REVIEW” instead of labeling them as “NOT ENOUGH INFO” or “REFUTES”.\nIn the literature, the shared task has been tackled using pipeline-based supervised models (BIBREF9; BIBREF10; BIBREF11). To our knowledge, only BIBREF10 has provided the confusion matrix for each of the labels for their supervised system. For the same reason, we are only providing the comparison of the label accuracy on the “SUPPORTS” label in the results section.\nIn this paper, we propose an unsupervised question-answering based approach for solving the fact-checking problem.",

        "evidence": "Nirvana was an American rock band formed in Aberdeen, Washington, in 1987. Founded by lead singer and guitarist Kurt Cobain and bassist Krist Novoselic, the band went through a succession of drummers, most notably Chad Channing, and then recruited Dave Grohl in 1990. Nirvana's success popularized alternative rock, and they were often referenced as the figurehead band of Generation X. Their music maintains a popular following and continues to influence modern rock culture.\n\nIn the late 1980s, Nirvana established itself as part of the Seattle grunge scene, releasing its first album, Bleach, for the independent record label Sub Pop in 1989. They developed a sound that relied on dynamic contrasts, often between quiet verses and loud, heavy choruses. After signing to major label DGC Records in 1991, Nirvana found unexpected mainstream success with \"Smells Like Teen Spirit\", the first single from their landmark second album Nevermind (1991). A cultural phenomenon of the 1990s, Nevermind was certified Diamond by the RIAA and is credited for ending the dominance of hair metal.\n\nCharacterized by their punk aesthetic, Nirvana's fusion of pop melodies with noise, combined with their themes of abjection and social alienation, brought them global popularity. Following extensive tours and the 1992 compilation album Incesticide and EP Hormoaning, the band released their highly anticipated third studio album, In Utero (1993). The album topped both the US and UK album charts, and was acclaimed by critics. Nirvana disbanded following Cobain's suicide in April 1994. Further releases have been overseen by Novoselic, Grohl, and Cobain's widow, Courtney Love. The live album MTV Unplugged in New York (1994) won Best Alternative Music Performance at the 1996 Grammy Awards.\n\nNirvana is one of the best-selling bands of all time, having sold more than 75 million records worldwide. During their three years as a mainstream act, Nirvana received an American Music Award, Brit Award and Grammy Award, as well as seven MTV Video Music Awards and two NME Awards. They achieved five number-one hits on the Billboard Alternative Songs chart and four number-one albums on the Billboard 200. In 2004, Rolling Stone named Nirvana among the 100 greatest artists of all time. They were inducted into the Rock and Roll Hall of Fame in their first year of eligibility in 2014.",

        "evidence": "Datasets: We use two recent benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . These two datasets are created to avoid reversible relation problems, thus the prediction task becomes more realistic and hence more challenging BIBREF18 . Table TABREF7 presents the statistics of WN18RR and FB15k-237.\nEvaluation protocol: Following BIBREF3 , for each valid test triple INLINEFORM0 , we replace either INLINEFORM1 or INLINEFORM2 by each of all other entities to create a set of corrupted triples. We use the “Filtered” setting protocol BIBREF3 , i.e., not taking any corrupted triples that appear in the KG into accounts. We rank the valid test triple and corrupted triples in descending order of their scores. We employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions). Lower MR, higher MRR or higher Hits@10 indicate better performance. Final scores on the test set are reported for the model obtaining the highest Hits@10 on the validation set.\nTraining protocol: We use the common Bernoulli strategy BIBREF20 , BIBREF21 when sampling invalid triples. For WN18RR, BIBREF22 found a strong evidence to support the necessity of a WordNet-related semantic setup, in which they averaged pre-trained word embeddings for word surface forms within the WordNet to create synset embeddings, and then used these synset embeddings to initialize entity embeddings for training their TransE association model. We follow this evidence in using the pre-trained 100-dimensional Glove word embeddings BIBREF23 to train a TransE model on WN18RR.\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 . For ConvKB, we use a new process of training up to 100 epochs and monitor the Hits@10 score after every 10 training epochs to choose optimal hyper-parameters with the Adam initial learning rate in INLINEFORM0 and the number of filters INLINEFORM1 in INLINEFORM2 . We obtain the highest Hits@10 scores on the validation set when using N= 400 and the initial learning rate INLINEFORM3 on WN18RR; and N= 100 and the initial learning rate INLINEFORM4 on FB15k-237.\nLike in ConvKB, we use the same pre-trained entity and relation embeddings produced by TransE to initialize entity and relation embeddings in our CapsE for both WN18RR and FB15k-237 ( INLINEFORM0 ). We set the batch size to 128, the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM1 ), and the number of iterations in the routing algorithm INLINEFORM2 in INLINEFORM3 . We run CapsE up to 50 epochs and monitor the Hits@10 score after each 10 training epochs to choose optimal hyper-parameters. The highest Hits@10 scores for our CapsE on the validation set are obtained when using INLINEFORM4 , INLINEFORM5 and the initial learning rate at INLINEFORM6 on WN18RR; and INLINEFORM7 , INLINEFORM8 and the initial learning rate at INLINEFORM9 on FB15k-237.\nDataset: We use the SEARCH17 dataset BIBREF12 of query logs of 106 users collected by a large-scale web search engine. A log entity consists of a user identifier, a query, top-10 ranked documents returned by the search engine and clicked documents along with the user's dwell time. BIBREF12 constructed short-term (session-based) user profiles and used the profiles to personalize the returned results. They then employed the SAT criteria BIBREF26 to identify whether a returned document is relevant from the query logs as either a clicked document with a dwell time of at least 30 seconds or the last clicked document in a search session (i.e., a SAT click). After that, they assigned a INLINEFORM0 label to a returned document if it is a SAT click and also assigned INLINEFORM1 labels to the remaining top-10 documents. The rank position of the INLINEFORM2 labeled documents is used as the ground truth to evaluate the search performance before and after re-ranking.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set BIBREF12 . The training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.\nEvaluation protocol: Our CapsE is used to re-rank the original list of documents returned by a search engine as follows: (i) We train our model and employ the trained model to calculate the score for each INLINEFORM0 triple. (ii) We then sort the scores in the descending order to obtain a new ranked list. To evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1. For each metric, the higher value indicates better ranking performance.\nWe compare CapsE with the following baselines using the same experimental setup: (1) SE: The original rank is returned by the search engine. (2) CI BIBREF27 : This baseline uses a personalized navigation method based on previously clicking returned documents. (3) SP BIBREF9 , BIBREF11 : A search personalization method makes use of the session-based user profiles. (4) Following BIBREF12 , we use TransE as a strong baseline model for the search personalization task. Previous work shows that the well-known embedding model TransE, despite its simplicity, obtains very competitive results for the knowledge graph completion BIBREF28 , BIBREF29 , BIBREF14 , BIBREF30 , BIBREF15 . (5) The CNN-based model ConvKB is the most closely related model to our CapsE.\nEmbedding initialization: We follow BIBREF12 to initialize user profile, query and document embeddings for the baselines TransE and ConvKB, and our CapsE.\nWe train a LDA topic model BIBREF31 with 200 topics only on the relevant documents (i.e., SAT clicks) extracted from the query logs. We then use the trained LDA model to infer the probability distribution over topics for every returned document. We use the topic proportion vector of each document as its document embedding (i.e. INLINEFORM0 ). In particular, the INLINEFORM1 element ( INLINEFORM2 ) of the vector embedding for document INLINEFORM3 is: INLINEFORM4 where INLINEFORM5 is the probability of the topic INLINEFORM6 given the document INLINEFORM7 .\nWe also represent each query by a probability distribution vector over topics. Let INLINEFORM0 be the set of top INLINEFORM1 ranked documents returned for a query INLINEFORM2 (here, INLINEFORM3 ). The INLINEFORM4 element of the vector embedding for query INLINEFORM5 is defined as in BIBREF12 : INLINEFORM6 , where INLINEFORM7 is the exponential decay function of INLINEFORM8 which is the rank of INLINEFORM9 in INLINEFORM10 . And INLINEFORM11 is the decay hyper-parameter ( INLINEFORM12 ). Following BIBREF12 , we use INLINEFORM13 . Note that if we learn query and document embeddings during training, the models will overfit to the data and will not work for new queries and documents. Thus, after the initialization process, we fix (i.e., not updating) query and document embeddings during training for TransE, ConvKB and CapsE.\nIn addition, as mentioned by BIBREF9 , the more recently clicked document expresses more about the user current search interest. Hence, we make use of the user clicked documents in the training set with the temporal weighting scheme proposed by BIBREF11 to initialize user profile embeddings for the three embedding models.\nHyper-parameter tuning: For our CapsE model, we set batch size to 128, and also the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM0 ). The number of iterations in the routing algorithm is set to 1 ( INLINEFORM1 ). For the training model, we use the Adam optimizer with the initial learning rate INLINEFORM2 INLINEFORM3 INLINEFORM4 INLINEFORM5 INLINEFORM6 INLINEFORM7 . We also use ReLU as the activation function INLINEFORM8 . We select the number of filters INLINEFORM9 .

        "question": "Given this article about the NSA's ANT Catalog, which hacking tools can be used to monitor a target's key strokes?",
        "evidence": "The ANT catalog (or TAO catalog) is a classified product catalog by the U.S. National Security Agency (NSA) of which the version written in 2008–2009 was published by German news magazine Der Spiegel in December 2013. Forty-nine catalog pages with pictures, diagrams and descriptions of espionage devices and spying software were published. The items are available to the Tailored Access Operations unit and are mostly targeted at products from US companies such as Apple, Cisco and Dell. The source is believed to be someone different than Edward Snowden, who is largely responsible for the global surveillance disclosures since 2013. Companies whose products could be compromised have denied any collaboration with the NSA in developing these capabilities. In 2014, a project was started to implement the capabilities from the ANT catalog as open-source hardware and software.\n\nBackground\nThe Tailored Access Operations unit has existed since the late 90s. Its mission is to collect intelligence on foreign targets of the United States by hacking into computers and telecommunication networks.\n\nIn 2012, Edward Snowden organized a CryptoParty together with Runa Sandvik, a former colleague of Jacob Appelbaum at The Tor Project. In June 2013, Snowden took internal NSA documents which he shared with Glenn Greenwald and Laura Poitras, resulting in the global surveillance disclosures. It has been speculated for years before that capabilities like those in the ANT catalog existed.\n\nPublication\nJacob Appelbaum co-authored the English publication in Der Spiegel with Christian Stöcker  and Judith Horchert, which was publicized on 29 December 2013. The related English publication on the same day about the TAO by Der Spiegel was also authored by the same people, and including Laura Poitras, Marcel Rosenbach, Jörg Schindler and Holger Stark. On December 30, Appelbaum gave a lecture about \"the militarization of the Internet\" at the 30th Chaos Communication Congress in Hamburg, Germany. At the end of his talk, he encouraged NSA employees to leak more documents.\n\nApple denied the allegations that it collaborated on the development of DROPOUTJEEP in a statement to journalist Arik Hesseldahl from All Things Digital (part of the Wall Street Journal's Digital Network). The Verge questioned how the program developed in later years, since the document was composed in the early period of the iPhone and smartphones in general. Dell denied collaborating with any government in general, including the US government. John Stewart, senior vice president and chief security officer of Cisco stated that they were \"deeply concerned and will continue to pursue all avenues to determine if we need to address any new issues.\" Juniper stated that they were working actively to address any possible exploit paths. Huawei stated they would take appropriate audits to determine if any compromise had taken place and would communicate if that had taken place. NSA declined to comment on the publication by Der Spiegel.\n\nSource\nThe source who leaked the ANT catalog to the press is unknown as of 2023.\n\nAuthor James Bamford, who is specialized in the United States intelligence agencies, noted in a commentary article published by Reuters that Appelbaum has not identified the source who leaked the ANT catalog to him, which led people to mistakenly assume it was Edward Snowden. Bamford got unrestricted access to the documents cache from Edward Snowden and could not find any references to the ANT catalog using automated search tools, thereby concluding that the documents were not leaked by him. Security expert Bruce Schneier has stated on his blog that he also believes the ANT catalog did not come from Snowden, but from a second leaker. Officials at the NSA did not believe that the web crawler used by Snowden touched the ANT catalog and started looking for other people who could have leaked the catalog.\n\nContent\nThe published catalog pages were written between 2008 and 2009. The price of the items ranged from free up to $250,000.\n\nCapabilities in the ANT catalog \nPage\tCode name\tDescription\tUnit price in US$\nNSA CANDYGRAM.jpg\tCANDYGRAM\tTripwire device that emulates a GSM cellphone tower.\t40,000\nNSA COTTONMOUTH-I.jpg\tCOTTONMOUTH-I\tFamily of modified USB and Ethernet connectors that can be used to install Trojan horse software and work as wireless bridges, providing covert remote access to the target machine.

John Bumgarner has stated to IEEE Spectrum that US government suspicion of Huawei is based on its own ability to add backdoors as shown in the ANT catalog.\n\nNSA Playset\nThe NSA Playset is an open-source project inspired by the NSA ANT catalog to create more accessible and easy to use tools for security researchers. Most of the surveillance tools can be recreated with off-the-shelf or open-source hardware and software. Thus far, the NSA Playset consists of fourteen items, for which the code and instructions can be found online on the project's homepage. After the initial leak, Michael Ossman, the founder of Great Scott Gadgets, gave a shout out to other security researchers to start working on the tools mentioned in the catalog and to recreate them. The name NSA Playset came originally from Dean Pierce, who is also a contributor (TWILIGHTVEGETABLE(GSM)) to the NSA Playset. Anyone is invited to join and contribute their own device. The requisites for an addition to the NSA Playset is a similar or already existing NSA ANT project, ease of use and a silly name (based on the original tool's name if possible). The silly name requisite is a rule that Michael Ossman himself came up with and an example is given on the project's website: \"For example, if your project is similar to FOXACID, maybe you could call it COYOTEMETH.\" The ease of use part stems also from the NSA Playset's motto: \"If a 10 year old can't do it, it doesn't count!\"\n\nName\tDescription\nTWILIGHTVEGETABLE\ta boot image for GSM communication monitoring.\nLEVITICUS\ta hand held GSM frequency analyzer disguised as a Motorola phone; named after GENESIS.\nDRIZZLECHAIR\ta hard drive with all the needed tools to crack A5/1 including the rainbow tables.\nPORCUPINEMASQUERADE\ta passive Wi-Fi reconnaissance drone.\nKEYSWEEPER\ta keylogger in form of a USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM).\nSLOTSCREAMER\ta PCI hardware implant, which can access memory and IO.\nADAPTERNOODLE\ta USB exploitation device.\nCHUKWAGON\tuses a pin on a computer's VGA port to attack via the I²C bus accessing the computer's operating system.\nTURNIPSCHOOL\ta hardware implant concealed in a USB cable which provides short range radio frequency communication capability to software running on the host computer.\nBLINKERCOUGH\ta hardware implant that is embedded in a VGA cable which allows data exfiltration.\nSAVIORBURST\ta hardware implant exploiting the JTAG interface for software application persistence; named after GODSURGE.

Melange deposits are found in the sand seas of Arrakis, where the sandworms live and hunt, and harvesting the spice from the sand is a dangerous activity because sandworms are aggressive and territorial. Harvesting vehicles must be airlifted in and out of the sand sea in order to evade sandworm attacks. The struggle over the production and supply of melange is a central theme of the Dune saga.",

In helicopters on the other hand, lift is generated by the spinning rotor blades. If the helicopter is in motion, the blades will produce more lift on the side where they are moving in the helicopter's direction of travel (advancing), than on the side where they are moving in the opposite direction (retreating). This is called dissymetry of lift. The faster the helicopter flies, the bigger this dissymetry will get.

        "evidence": "On the face of it, Arizona, a state known for its Grand Canyon and barren deserts, might seem an odd choice for an industry that demands huge amounts of water. But water, it turns out, is one of the least concerns. Semiconductor manufacturing needs a big ecosystem to get the best cost position. Semiconductor manufacturing need to have not just one company or one fab, but a big cluster of 10 to 15 of these things, to be able to get that world class performance and to be able to build a big enough ecosystem around you.This includes everything from equipment suppliers, which are needed to update and perform maintenance on chipmaking machines, to companies providing chemicals and other materials needed in making chips.Arizona has such a complete semiconductor supply chain already is thanks in no small part to Intel. Back in 1980, Intel started manufacturing microcontroller chips at its facility in Chandler, Arizona which is now Intel's largest manufacturing site in the world. In addition to Intel, leading semiconductor makers including NXP, ON Semiconductor, Qualcomm, Microchip, Broadcom and Benchmark Electronics have also built facilities in the state. Apart from its cluster of semiconductor companies, geopolitics have also worked in Arizona's favor.

        "question": "What factor determine the size needed for a computational text analysis?",
        "answer": "The research goal.",
        "evidence": "Many scholars in the humanities and the social sciences work with sources that are not available in digital form, and indeed may never be digitized. Others work with both analogue and digitized materials, and the increasing digitization of archives has opened opportunities to study these archives in new ways. We can go to the canonical archive or open up something that nobody has studied before. For example, we might focus on major historical moments (French Revolution, post-Milosevic Serbia) or critical epochs (Britain entering the Victorian era, the transition from Latin to proto-Romance). Or, we could look for records of how people conducted science, wrote and consumed literature, and worked out their philosophies.\nA growing number of researchers work with born-digital sources or data. Born-digital data, e.g., from social media, generally do not involve direct elicitation from participants and therefore enable unobtrusive measurements BIBREF5 , BIBREF6 . In contrast, methods like surveys sometimes elicit altered responses from participants, who might adapt their responses to what they think is expected. Moreover, born-digital data is often massive, enabling large-scale studies of language and behavior in a variety of social contexts.\nStill, many scholars in the social sciences and humanities work with multiple data sources. The variety of sources typically used means that more than one data collection method is often required. For example, a project examining coverage of a UK General Election, could draw data from traditional media, web archives, Twitter and Facebook, campaign manifestos, etc. and might combine textual analysis of these materials with surveys, laboratory experiments, or field observations offline. In contrast, many computational studies based on born-digital data have focused on one specific source, such as Twitter.\nThe use of born-digital data raises ethical concerns. Although early studies often treated privacy as a binary construct, many now acknowledge its complexity BIBREF7 . Conversations on private matters can be posted online, visible for all, but social norms regarding what should be considered public information may differ from the data's explicit visibility settings. Often no informed consent has been obtained, raising concerns and challenges regarding publishing content and potentially harmful secondary uses BIBREF8 , BIBREF4 .\nRecently, concerns about potential harms stemming from secondary uses have led a number of digital service providers to restrict access to born-digital data. Facebook and Twitter, for example, have reduced or eliminated public access to their application programming interfaces (APIs) and expressed hesitation about allowing academic researchers to use data from their platforms to examine certain sensitive or controversial topics. Despite the seeming abundance of born-digital data, we therefore cannot take its availability for granted.\nWorking with data that someone else has acquired presents additional problems related to provenance and contextualisation. It may not always be possible to determine the criteria applied during the creation process. For example, why were certain newspapers digitized but not others, and what does this say about the collection? Similar questions arise with the use of born-digital data. For instance, when using the Internet Archive’s Wayback Machine to gather data from archived web pages, we need to consider what pages were captured, which are likely missing, and why.\nWe must often repurpose born-digital data (e.g., Twitter was not designed to measure public opinion), but data biases may lead to spurious results and limit justification for generalization. In particular, data collected via black box APIs designed for commercial, not research, purposes are likely to introduce biases into the inferences we draw, and the closed nature of these APIs means we rarely know what biases are introduced, let alone how severely they might impact our research BIBREF10 . These, however, are not new problems. Historians, for example, have always understood that their sources were produced within particular contexts and for particular purposes, which are not always apparent to us.\nNon-representative data can still be useful for making comparisons within a sample. In the introductory example on hate speech BIBREF0 , the Reddit forums do not present a comprehensive or balanced picture of hate speech: the writing is almost exclusively in English, the targets of hate speech are mainly restricted (e.g., to black people, or women), and the population of writers is shaped by Reddit's demographics, which skew towards young white men. These biases limit the generalizability of the findings, which cannot be extrapolated to other languages, other types of hate speech, and other demographic groups. However, because the findings are based on measurements on the same sort of hate speech and the same population of writers, as long as the collected data are representative of this specific population, these biases do not pose an intractable validity problem if claims are properly restricted.\nThe size of many newly available datasets is one of their most appealing characteristics. Bigger datasets often make statistics more robust. The size needed for a computational text analysis depends on the research goal: When it involves studying rare events, bigger datasets are needed. However, larger is not always better. Some very large archives are “secretly” collections of multiple and distinct processes that no in-field scholar would consider related. For example, Google Books is frequently used to study cultural patterns, but the over-representation of scientific articles in Google books can be problematic BIBREF11 . Even very large born-digital datasets usually cover limited timespans compared to, e.g., the Gutenberg archive of British novels.\nThis stage of the research also raises important questions about fairness. Are marginalized groups, for example, represented in the tweets we have collected? If not, what types of biases might result from analyses relying on those tweets?\nLocal experts and “informants” can help navigate the data. They can help understand the role an archive plays in the time and place. They might tell us: Is this the central archive, or a peripheral one? What makes it unusual? Or they might tell us how certain underrepresented communities use a social media platform and advise us on strategies for ensuring our data collection includes their perspectives.\nHowever, when it is practically infeasible to navigate the data in this way—for instance, when we cannot determine what is missing from Twitter's Streaming API or what webpages are left out of the Internet Archive—we should be open about the limitations of our analyses, acknowledging the flaws in our data and drawing cautious and reasonable conclusions from them. In all cases, we should report the choices we have made when creating or re-using any dataset.\nThe size needed for a computational text analysis depends on the research goal: When it involves studying rare events, bigger datasets are needed.",

        "evidence": "",
        "answer": "There are infinite ways to create interesting flavours, that are either personal favourites or attempt to replicate classic beers and beer styles. There are a number of factors that make up a beers flavour profile and part of the enjoyment brewing your own beer at home, is that you can play around with each of these to change the flavour and character of your homebrew beer. Here are five ways in which you can change your own homebrew recipe to add interesting flavours or alternatively you can alter an existing homebrew recipe shared by somebody else or a brewery.\n\n1. Use different hops\nThere is a huge variety of hops available to homebrewers and each of these can introduce its own particular flavour and aroma to your beer, ranging from pineapple and apricots, to pine trees and woods, to grapefruit pith and lemon zest. By using a different hop in your recipe either from the same family or from an entirely different family of hops, you can easily add interesting and often radical changes to the flavour profile of your beer. However, depending on when the hops are added in the brewing process, you can also increase/decrease the levels of bitterness of your beer, due to different hop varieties having different levels of alpha acids.\n\n2. Use a different yeast\nBesides fermenting the beer, yeast leave behind lots of interesting flavours and can give your homebrew it's own subtle character. For example, English yeast strains can add malty and sweet flavours, California yeast tends to create a clean and crisp beer, whilst saison yeast adds bright and fruity flavours to your beer.\n\n3. Use different grains\nChanging the amount of base malts can increase or decrease the alcohol in your finished beer. Trying swapping one base malt for another, like American pale malts for a British variety, and look for the subtle differences between them. You can also play around with the specialty grains, like using a slightly darker roast.\n\n4. Add fruit, spices or herbs\nFruits, spices, herbs, and other ingredients are a great way to add an entirely personal character to your homebrew. Anything from fresh strawberries and basil to vanilla beans and cardamom can really complement the other malty, hoppy flavours in a beer. \n\n5. Alter your water profile\nDifferent beer styles will typically be best achieved with a suitable water profile, with different levels of minerals to achieve the desired flavour profile. By adjusting the amounts of specific minerals found in your brewing water, beer can be made to taste fuller bodied, sweeter, drier, more bitter, or even sour.",

        "question": "Do UIT-ViIC’s guidelines have similar rules in comparison with MS-COCO?",
        "answer": "Yes.",
        "evidence": "In this section, we describes procedures of building our sportball Vietnamese dataset, called UIT-ViIC.\nOur human resources for dataset construction involve five writers, whose ages are from 22-25. Being native Vietnamese residents, they are fluent in Vietnamese. All five UIT-ViIC creators first research and are trained about sports knowledge as well as the specialized vocabulary before starting to work.\nDuring annotation process, there are inconsistencies and disagreements between human's understandings and the way they see images. According to Micah Hodosh et al BIBREF5, most images’ captions on Internet nowadays tend to introduce information that cannot be obtained from the image itself, such as people name, location name, time, etc. Therefore, to successfully compose meaningful descriptive captions we expect, their should be strict guidelines.\nInspired from MS-COCO annotation rules BIBREF16, we first sketched UIT-ViIC's guidelines for our captions:\nEach caption must contain at least ten Vietnamese words.\nOnly describe visible activities and objects included in image.\nExclude name of places, streets (Chinatown, New York, etc.) and number (apartment numbers, specific time on TV, etc.)\nFamiliar English words such as laptop, TV, tennis, etc. are allowed.\nEach caption must be a single sentence with continuous tense.\nPersonal opinion and emotion must be excluded while annotating.\nAnnotators can describe the activities and objects from different perspectives.\nVisible “thing” objects are the only one to be described.\nAmbiguous “stuff” objects which do not have obvious “border” are ignored.\nIn case of 10 to 15 objects which are in the same category or species, annotators do not need to include them in the caption.\nIn comparison with MS-COCO BIBREF16 data collection guidelines in terms of annotation, UIT-ViIC’s guidelines has similar rules (1, 2, 8, 9, 10) . We extend from MS-COCO’s guidelines with five new rules to our own and have modifications in the original ones.\nIn both datasets, we would like to control sentence length and focus on describing important subjects only in order to make sure that essential information is mainly included in captions. The MS-COCO threshold for sentence’s length is 8, and we raise the number to 10 for our dataset. One reason for this change is that an object in image is usually expressed in many Vietnamese words. For example, a “baseball player” in English can be translated into “vận động viên bóng chày” or “cầu thủ bóng chày”, which already accounted for a significant length of the Vietnamese sentence. In addition, captions must be single sentences with continuous tense as we expect our model’s output to capture what we are seeing in the image in a consise way.\nOn the other hand, proper name for places, streets, etc must not be mentioned in this dataset in order to avoid confusions and incorrect identification names with the same scenery for output. Besides, annotators’ personal opinion must be excluded for more meaningful captions. Vietnamese words for several English ones such as tennis, pizza, TV, etc are not existed, so annotators could use such familiar words in describing captions. For some images, the subjects are ambiguous and not descriptive which would be difficult for annotators to describe in words. That’s the reason why annotators can describe images from more than one perspective.\nIn comparison with MS-COCO data collection guidelines in terms of annotation, UIT-ViIC’s guidelines has similar rules (1, 2, 8, 9, 10) .",

The corpus comprises 8,275 sentences and 167,739 words in total. However, as mentioned above, only case presentation sections, headings and abstracts are annotated. The numbers of annotated entities are summarized in Table TABREF24.\nFindings are the most frequently annotated type of entity. This makes sense given that findings paint a clinical picture of the patient's condition. The number of tokens per entity ranges from one token for all types to 5 tokens for cases (average length 3.1), nine tokens for conditions (average length 2.0), 16 tokens for factors (average length 2.5), 25 tokens for findings (average length 2.6) and 18 tokens for modifiers (average length 1.4) (cf. Table TABREF24). Examples of rather long entities are given in Table TABREF25.\nEntities can appear in a discontinuous way. We model this as a relation between two spans which we call “discontinuous” (cf. Figure FIGREF26). Especially findings often appear as discontinuous entities, we found 543 discontinuous finding relations. The numbers for conditions and factors are lower with seven and two, respectively. Entities can also be nested within one another. This happens either when the span of one annotation is completely embedded in the span of another annotation (fully-nested; cf. Figure FIGREF12), or when there is a partial overlapping between the spans of two different entities (partially-nested; cf. Figure FIGREF12). There is a high number of inter-sentential relations in the corpus (cf. Table TABREF27). This can be explained by the fact that the case entity occurs early in each document; furthermore, it is related to finding and factor annotations that are distributed across different sentences.\nThe most frequently annotated relation in our corpus is the has-relation between a case entity and the findings related to that case.

        "evidence": "Along the actor dimension, Figure 6 shows which full actor codings appear most often in the dataset. As one would expect, state actors account for most of the events, with the only outlier the IMGMOSISI which is the actor code for the Islamic State in Iraq and the Levant. This pattern also holds for just the entity codings, which could be either a state code or a few other important codings such as IGOs.\nIt is possible to break the actor codes down further to examine role codes, which account for more specific functions that a specific actor performs within a given country such as military or business. Figure 8 shows that the most common role code is government actors (GOV). Following the GOV role are military (MIL) and rebel (REB) codes.\nIn order to better understand how the dataset is performing it is helpful to pull out a specific case and examine a similar set of attributes as seen in the previous section. One of the major, ongoing events in the international arena during the time currently covered by the Phoenix dataset is the conflict in Syria. Given this, I extract any events that contain the Syria country code, SYR, as the SourceActorEntity or TargetActorEntity. Figure 9 shows the plot of the daily aggregated event counts. In this plot it is possible to see actions such as the beginning of United State intervention against ISIL, along with other significant events within the country. As with any event data, it is important to note that the event counts shown do not represent the on-the-ground truth of events in Syria, but instead reflect the media coverage of said events. Thus, some of the peaks and troughs are the result of media coverage instead of any actual shift in reality. In order to provide more context to the time series, Figure 10 shows the breakout of the QuadClass variable for this data subset. The dominant event types are the low-level events described in the previous section, but the “Material Conflict” class is higher than in the broader dataset. This is, of course, as expected given the ongoing conflict within Syria.\nFigures 11 and 12 show the top actor and entity codes for the Syria subset. Various Syrian actors appear most often, with other Middle East countries also accounting for a fairly high portion of events. Also seen within this group of top actors is ISIL and the United States. Additionally, Russia appears high in the rankings of actors within Syria, capturing the recent activity by Russian forces in support of the Assad regime.\nOverall, the Syrian subset of the data suggests that the Phoenix dataset is doing an adequate job of picking up events of interest in a conflict zone. The actor and event distributions follow what one would expect for the Syrian conflict. Additionally, there are no obvious errors in which actors make up the top participants in the subset. This examination provides confidence that the dataset is “working” in terms of face validity.\nIt is possible to break the actor codes down further to examine role codes, which account for more specific functions that a specific actor performs within a given country such as military or business.",

        "question": "Should we continue to use Daylight savings?",
        "evidence": "",
        "answer": "While it is hard for our bodies to adjust to and oftentimes inconvenient, daylight savings time should be maintained in the USA as it saves energy, money, and lives.\n\tDaylight savings, though sometimes disrupting, helps to limit the energy wasted by Americans during the summer months. Source A reveals that, beginning in the USA in 1918, daylight saving time was originally a way to reduce energy usage during World War I. While it was repealed shortly thereafter, daylight savings was again suggested by President Roosevelt during World War II. Though inconvenient, Americans did take notice of the benefits: saving money on energy. The continued testing of daylight savings’ effects on Americans lasted through the 20th century and was written into law in 2005. Despite the skepticism from Americans over the potential drawbacks of daylight saving, the reaped benefits of saved energy and money mutually benefited the American government, economy, and citizens, all of which are still benefitting today.\n\tThe ability to save unnecessary energy now benefit’s the American economy in the long run. In Source B, Longley cites a 1970s study by the U.S. Department of Transportation, which revealed that while daylight savings is in effect, America's electricity consumption is reduced by about one percent. Reducing one percent of America’s energy consumption would save Americans money. Also in Source B is the proposal for a provision to the Energy Policy Act of 2005, which would extend daylight savings an extra month and would allow oil drilling in Alaska, both of which would boost the American economy. The extension of daylight savings would overall save more money than it would spend.\n\tDespite the beneficial economic aspects of daylight saving, many dislike the time change because it affects their body schedules and daily routines. Source E claims that when the clock is moved forward or back, the body’s internal clock cannot adjust so quickly, leading to restlessness, sleep disruption, and shorter sleeping periods. The time change has also been found to link with increased heart attacks, suicides, and accidents. While the body’s internal clock may take a longer time to adjust to daylight savings time, it doesn’t outweigh the economic benefits the USA gains as a whole. Source E cites a study of 55,000 people whose sleep schedules were tracked after the time change, claiming that the subjects tended to sleep on standard time rather than daylight time, not taking into account the potential variables of age, weekend events or activities, or even the body’s natural reaction to wake up at a certain time. The study also reveals no harmful effects of the difference between sleeping on standard versus daylight savings time.\n\tWhile Source E argued that daylight savings time had more dangerous effects on people than remaining on standard time, daylight savings time can actually benefit people’s safety. In Source C, a cited study by the U.S. Department of Transportation found that during daylight saving time, there was a severe reduction in crime by ten to thirteen percent. By changing the clocks and altering the amount of sunlight during the day, people were generally less likely to become involved in any street crime taking place. The Department of Transportation also found that daylight savings time helped to increase traffic safety, as the clocks were altered to match the periods of daylight, causing fewer accidents. Daylight savings overall led to safer daily activities, while still saving money and energy.\n\tDaylight savings has been long disputed over: should we inconvenience ourselves just to save a little energy? Despite many people’s dislike of the changing times, daylight savings is generally beneficial to America, as it saves energy, reduces energy costs and bills for Americans, and creates a safer environment for people to live in.

Nobody has yet stepped forward to pay the large fees that certification involves, so we're not allowed to call it Unix. Certification really doesn't mean very much anyway. Very few of the commercial operating systems have passed the Open Group tests.\n\nUnofficially, Linux is very similar to the operating systems which are known as Unix, and for many purposes they are equivalent. Linux the kernel is an operating system kernel that behaves and performs similarly to the famous Unix operating system from AT&T Bell Labs. Linux is often called a \"Unix-like\" operating system.

        "evidence": "To simulate a diverse multi-domain setting we use the dataset proposed in BIBREF8, as it was recently adopted for domain adaptation research in NMT BIBREF28, BIBREF29, BIBREF30, BIBREF31. The dataset includes parallel text in German and English from five diverse domains (Medical, Law, Koran, IT, Subtitles; as discussed in Section SECREF2), available via OPUS BIBREF32, BIBREF33.\nIn a preliminary analysis of the data we found that in both the original train/dev/test split by BIBREF8 and in the more recent split by BIBREF29 there was overlap between the training data and the dev/test data. Fixing these issues is important, as it may affect the conclusions one draws from experiments with this dataset. For example, as overlapping development sets favor memorization of the training set, one may choose checkpoints and report results on over-fitting models. This is especially relevant with neural sequence-to-sequence models, as they are highly susceptible to memorization BIBREF34 and hallucination BIBREF35, as confirmed by BIBREF29.\nTo create a better experimental setting to test generalization within and across domains, we create a new data split where we ensure that no such overlap between the training, development and test sets occur. We started from the split of BIBREF29 as it included newer versions of some of the datasets. Furthermore, we did not allow more than one translation of a given source or target sentence, as such cases were very frequent in the dataset and usually stand for duplicate sentence pairs (See Table TABREF24). For example, applying this filtering reduced the size of the Koran corpus from 533,128 sentence pairs to only 17,982. Finally, following BIBREF29 we cap the subtitles corpus to 500,000 sentence pairs as it is much larger than the rest. We make the new split publicly available and hope it will enable better future experimentation on this important subject.\nTo simulate a diverse multi-domain setting we use the dataset proposed in Koehn and Knowles (2017),as it was recently adopted for domain adaptation research in NMT.",

        "question": "What is electrostatics the study of?",
        "evidence": "The concept of the electric field was introduced by Michael Faraday. An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field. The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses, and like it, extends towards infinity and shows an inverse square relationship with distance. However, there is an important difference. Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion. Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero. Thus gravity is the dominant force at distance in the universe, despite being much weaker.\nAn electric field generally varies in space and its strength at any one point is defined as the force (per unit charge) that would be felt by a stationary, negligible charge if placed at that point. The conceptual charge, termed a 'test charge', must be vanishingly small to prevent its own electric field disturbing the main field and must also be stationary to prevent the effect of magnetic fields. As the electric field is defined in terms of force, and force is a vector, having both magnitude and direction, so it follows that an electric field is a vector field.\nThe study of electric fields created by stationary charges is called electrostatics. The field may be visualised by a set of imaginary lines whose direction at any point is the same as that of the field. This concept was introduced by Faraday, whose term 'lines of force' still sometimes sees use. The field lines are the paths that a point positive charge would seek to make as it was forced to move within the field; they are however an imaginary concept with no physical existence, and the field permeates all the intervening space between the lines. Field lines emanating from stationary charges have several key properties: first, that they originate at positive charges and terminate at negative charges; second, that they must enter any good conductor at right angles, and third, that they may never cross nor close in on themselves.",

        "answer": "(1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do the authors get about personal recovery and factors that facilitate or hinder it?",
        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it?",

        "evidence": "The main contribution of our paper is to suggest the use of a certain type of textual documents, namely daily weather report, to build forecasters of the daily national electricity load, average temperature and wind speed for both France and the United-Kingdom (UK). Consequently this work represents a significant break with traditional methods, and we do not intend to best state-of-the-art approaches. Textual information is naturally more fuzzy than numerical one, and as such the same accuracy is not expected from the presented approaches. With a single text, we were already able to predict the electricity consumption with a relative error of less than 5% for both data sets. Furthermore, the quality of our predictions of temperature and wind speed is satisfying enough to replace missing or unavailable data in traditional models. Two different approaches are considered to represent the text numerically, as well as multiple forecasting algorithms. Our empirical results are consistent across encoding, methods and language, thus proving the intrinsic value weather reports have for the prediction of the aforementioned time series. Moreover, a major distinction between previous works is our interpretation of the models. We quantify the impact of a word on the forecast and analyze the geometric properties of the word embedding we trained ourselves. Note that although multiple time series are discussed in our paper, the main focus of this paper remains electricity consumption. As such, emphasis is put on the predictive results on the load demand time series.\nWith a single text, we were already able to predict the electricity consumption with a relative error of less than 5% for both data sets.",

Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other.

        "evidence": "In the first experiment we perform an attribution of individual scenes of H8 using the Support Vector Machine as a classifier and the frequencies of 500 most frequent rhythmic types and the frequencies of 500 most frequent words as a feature set. As training samples, individual scenes of plays written by Shakespeare, Fletcher, and Massinger are used that come roughly from the period when H8 was supposedly written, namely:\nShakespeare: The Tragedy of Coriolanus (5 scenes), The Tragedy of Cymbeline (27 scenes), The Winter’s Tale (12 scenes), The Tempest (9 scenes)\nFletcher: Valentinian (21 scenes), Monsieur Thomas (28 scenes), The Woman’s Prize (23 scenes), Bonduca (18 scenes)\nMassinger: The Duke of Milan (10 scenes), The Unnatural Combat (11 scenes), The Renegado (25 scenes)\nAltogether there are thus 53 training samples for Shakespeare, 90 training samples for Fletcher and 46 training samples for Massinger. In order to estimate the accuracy of the model, cross-validation is performed in the following way:\nTo avoid the risk of overfitting which may be caused by testing the model on the scenes from the same play as it was trained on, we do not perform a standard k-fold cross validation. Instead, we classify scenes of each play by a model trained on the rest, i.e. 5 scenes of Shakespeare’s Coriolanus are classified by a model trained on the scenes from the remaining 3 plays by Shakespeare, 4 plays by Fletcher and 5 plays by Massinger, 27 scenes of Cymbeline are classified in the same way and so on.\nSince the training data are imbalanced (which may bias the results), we level the number of training samples per author by random selection.\nTo obtain more representative results, the entire process is repeated 30 times (with a new random selection in each iteration) thus resulting in 30 classifications of each scene.\nFor the sake of comparison of the attribution power of both feature subsets, cross-validations are performed not only of the combined models (500 words $\\cup $ 500 rhythmic types), but also of the words-based models (500 words) and versification-based models (500 rhythmic types) alone.\nAs shown in Table TABREF14, the versification-based models yield a very high accuracy with the recognition of Shakespeare and Fletcher (0.97 to 1 with the exception of Valentinian), yet slightly lower accuracy with the recognition of Massinger (0.81 to 0.88). The accuracy of words-based models remains very high across all three authors (0.95 to 1); in three cases it is nevertheless outperformed by the combined model. We thus may conclude that combined models provide a reliable discriminator between Shakespeare’s, Fletcher’s and Massinger’s styles.\nTable TABREF19 gives the results of the classifiers when applied to the individual scenes of H8 on the basis of which we may conclude:\nIt is very unlikely that Massinger took part in the text of H8. Out of 17 scenes only 2 are attributed to Massinger by any of the models (2.1, 4.2), and in both cases by a mere minority of votes.\nThe probability that the text of H8 is a result of collaboration between Shakespeare and Fletcher is very high: with 7 scenes all the 30 models agree upon Shakespeare’s authorship, with 5 scenes all the 30 models agree upon Fletcher’s authorship.\nOur results correspond to the Spedding’s attribution to a high extent. With the exception of two scenes, the majority of models always predict the same author to which it is attributed by Spedding. The two exceptions are the second scene of act 3, where Spedding supposed mixed authorship, and the first scene of act 4, which was originally attributed to Fletcher.\nIn the first experiment we perform an attribution of individual scenes of H8 using the Support Vector Machine as a classifier and the frequencies of 500 most frequent rhythmic types and the frequencies of 500 most frequent words as a feature set.",

        "answer": "Allowing infinite precision.",
        "evidence": "Recent work [1] suggests that recurrent “neural network\" models of several types perform better than sequential models in acquiring and processing hierarchical structure. Indeed, recurrent networks have achieved state-of-the-art results in a number of natural language processing tasks, including named-entity recognition [2], language modeling [3], sentiment analysis [4], natural language generation [5], and beyond.\nThe hierarchical structure associated with natural languages is often modeled as some variant of context-free languages, whose languages may be defined over an alphabet INLINEFORM0 . These context-free languages are exactly those that can be recognized by pushdown automata (PDAs). Thus it is natural to ask whether these modern natural language processing tools, including simple recurrent neural networks (RNNs) and other, more advanced recurrent architectures, can learn to recognize these languages.\nThe computational power of RNNs has been studied extensively using empirical testing. Much of this research [8], [9] focused on the ability of RNNs to recognize simple context-free languages such as INLINEFORM0 and INLINEFORM1 , or context-sensitive languages such as INLINEFORM2 . Related works [10], [11], [12] focus instead on Dyck languages of balanced parenthesis, which motivates some of our methods. Gated architectures such as the Gated Recurrent Unit (GRU) and Long Short-Term Memory (LSTM) obtain high accuracies on each of these tasks. While simpler RNNs have also been tested, one difficulty is that the standard hyperbolic tangent activation function makes counting difficult. On the other hand, RNNs with ReLU activations were found to perform better, but suffer from what is known as the “exploding gradient problem\" and thus are more difficult to train [8].\nInstead of focusing on a single task, many researchers have studied the broader theoretical computational power of recurrent models, where weights are not trained but rather initialized to recognize a desired language. A celebrated result [6] shows that a simple recurrent architecture with 1058 hidden nodes and a saturated-linear activation INLINEFORM0 is a universal Turing Machine, with: INLINEFORM1 \nHowever, their architecture encodes the whole input in its internal state and the relevant computation is only performed after reading a terminal token. This differs from more common RNN variants that consume tokenized inputs at each time step. Furthermore, the authors admit that were the saturated-linear activation to be replaced with the similar and more common sigmoid or hyperbolic tangent activation functions, their methodology would fail.\nMore recent work [7] suggests that single-layer RNNs with rectified linear unit (ReLU) activations and softmax outputs can also be simulated as universal Turing Machines, but this approach again suffers from the assumption that the entire input is read before computation occurs.\nMotivated by these earlier theoretical results, in this report we seek to show results about the computational power of recurrent architectures actually used in practice - namely, those that read tokens one at a time and that use standard rather than specially chosen activation functions. In particular we will prove that, allowing infinite precision, RNNs with just one hidden layer and ReLU activation are at least as powerful as PDAs, and that GRUs are at least as powerful as deterministic finite automata (DFAs). Furthermore, we show that using infinite edge weights and a non-standard output function, GRUs are also at least as powerful as PDAs.\nIn particular we will prove that, allowing infinite precision, RNNs with just one hidden layer and ReLU activation are at least as powerful as PDAs, and that GRUs are at least as powerful as deterministic finite automata (DFAs).",

Table TABREF47 presents instances where it predicts the wrong label with a high confidence. These examples indicate that many comments express their stance only on a very implicit level, and thus hint at a potential weakness of the dataset. Because on the voting advice platform the label is explicitly shown to readers in addition to the comments, the comments do not need to express the stance explicitly. Manual annotation could eliminate very implicit samples in a future version of the dataset. However, the sheer size and breadth of the dataset could not realistically be achieved with manual annotation, and, in our view, largely compensates for the implicitness of the texts.\nOur experiments show that M-BERT achieves a reasonable accuracy on X-stance, outperforming majority class baselines and a fastText classifier.",

Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension.

The point at which these layers meet is called an interface, and is where slipping or sliding of one layer on top of another is most likely to occur. This occurrence is what can trigger an avalanche.

        "evidence": "Many reinforcement learning algorithms are designed for relatively small discrete or continuous action spaces and so have trouble scaling. Text-adventure games—or interaction fictions—are simulations in which both an agents' state and action spaces are in textual natural language. An example of a one turn agent interaction in the popular text-game Zork1 can be seen in Fig. FIGREF1. Text-adventure games provide us with multiple challenges in the form of partial observability, commonsense reasoning, and a combinatorially-sized state-action space. Text-adventure games are structured as long puzzles or quests, interspersed with bottlenecks. The quests can usually be completed through multiple branching paths. However, games can also feature one or more bottlenecks. Bottlenecks are areas that an agent must pass through in order to progress to the next section of the game regardless of what path the agent has taken to complete that section of the quest BIBREF0. In this work, we focus on more effectively exploring this space and surpassing these bottlenecks—building on prior work that focuses on tackling the other problems.\nFormally, we use the definition of text-adventure games as seen in BIBREF1 and BIBREF2. These games are partially observable Markov decision processes (POMDPs), represented as a 7-tuple of $\\langle S,T,A,\\Omega , O,R, \\gamma \\rangle $ representing the set of environment states, mostly deterministic conditional transition probabilities between states, the vocabulary or words used to compose text commands, observations returned by the game, observation conditional probabilities, reward function, and the discount factor respectively. For our purposes, understanding the exact state and action spaces we use in this work is critical and so we define each of these in relative depth.\nAction-Space. To solve Zork1, the cannonical text-adventure games, requires the generation of actions consisting of up to five-words from a relatively modest vocabulary of 697 words recognized by the game’s parser. This results in $\\mathcal {O}(697^5)={1.64e14}$ possible actions at every step. To facilitate text-adventure game playing, BIBREF2 introduce Jericho, a framework for interacting with text-games. They propose a template-based action space in which the agent first selects a template, consisting of an action verb and preposition, and then filling that in with relevant entities $($e.g. $[get]$ $ [from] $ $)$. Zork1 has 237 templates, each with up to two blanks, yielding a template-action space of size $\\mathcal {O}(237 \\times 697^2)={1.15e8}$. This space is still far larger than most used by previous approaches applying reinforcement learning to text-based games.\nState-Representation. Prior work has shown that knowledge graphs are effective in terms of dealing with the challenges of partial observability $($BIBREF3 BIBREF3; BIBREF4$)$. A knowledge graph is a set of 3-tuples of the form $\\langle subject, relation, object \\rangle $. These triples are extracted from the observations using Stanford's Open Information Extraction (OpenIE) BIBREF5. Human-made text-adventure games often contain relatively complex semi-structured information that OpenIE is not designed to parse and so they add additional rules to ensure that the correct information is parsed. The graph itself is more or less a map of the world, with information about objects' affordances and attributes linked to the rooms that they are place in a map. The graph also makes a distinction with respect to items that are in the agent's possession or in their immediate surrounding environment. An example of what the knowledge graph looks like and specific implementation details can be found in Appendix SECREF14.\nBIBREF6 introduce the KG-A2C, which uses a knowledge graph based state-representation to aid in the section of actions in a combinatorially-sized action-space—specifically they use the knowledge graph to constrain the kinds of entities that can be filled in the blanks in the template action-space. They test their approach on Zork1, showing the combination of the knowledge graph and template action selection resulted in improvements over existing methods. They note that their approach reaches a score of 40 which corresponds to a bottleneck in Zork1 where the player is eaten by a “grue” (resulting in negative reward) if the player has not first lit a lamp. The lamp must be lit many steps after first being encountered, in a different section of the game; this action is necessary to continue exploring but doesn’t immediately produce any positive reward. That is, there is a long term dependency between actions that is not immediately rewarded, as seen in Figure FIGREF1. Others using artificially constrained action spaces also report an inability to pass through this bottleneck BIBREF7, BIBREF8. They pose a significant challenge for these methods because the agent does not see the correct action sequence to pass the bottleneck enough times. This is in part due to the fact that for that sequence to be reinforced, the agent needs to reach the next possible reward beyond the bottleneck.\nMore efficient exploration strategies are required to pass bottlenecks. Our contributions are two-fold. We first introduce a method that detects bottlenecks in text-games using the overall reward gained and the knowledge graph state. This method freezes the policy used to reach the bottleneck and restarts the training from there on out, additionally conducting a backtracking search to ensure that a sub-optimal policy has not been frozen. The second contribution explore how to leverage knowledge graphs to improve existing exploration algorithms for dealing with combinatorial action-spaces such as Go-Explore BIBREF9. We additionally present a comparative ablation study analyzing the performance of these methods on the popular text-game Zork1.\nBottlenecks are areas that an agent must pass through in order to progress to the next section of the game regardless of what path the agent has taken to complete that section of the quest (Stolle & Precup, 2002).",

        "answer": "It is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nFor such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.",

But while other NLP tasks have been extensively investigated, sarcasm detection is a relatively new research topic which has gained increasing interest only recently, partly thanks to the rise of social media analytics and sentiment analysis. Sentiment analysis BIBREF16 and using multimodal information as a new trend BIBREF17 , BIBREF18 , BIBREF19 , BIBREF20 , BIBREF14 is a popular branch of NLP research that aims to understand sentiment of documents automatically using combination of various machine learning approaches BIBREF21 , BIBREF22 , BIBREF20 , BIBREF23 .\nAn early work in this field was done by BIBREF6 on a dataset of 6,600 manually annotated Amazon reviews using a kNN-classifier over punctuation-based and pattern-based features, i.e., ordered sequence of high frequency words. BIBREF1 used support vector machine (SVM) and logistic regression over a feature set of unigrams, dictionary-based lexical features and pragmatic features (e.g., emoticons) and compared the performance of the classifier with that of humans. BIBREF24 described a set of textual features for recognizing irony at a linguistic level, especially in short texts created via Twitter, and constructed a new model that was assessed along two dimensions: representativeness and relevance. BIBREF5 used the presence of a positive sentiment in close proximity of a negative situation phrase as a feature for sarcasm detection. BIBREF25 used the Balanced Window algorithm for classifying Dutch tweets as sarcastic vs. non-sarcastic; n-grams (uni, bi and tri) and intensifiers were used as features for classification.\n BIBREF26 compared the performance of different classifiers on the Amazon review dataset using the imbalance between the sentiment expressed by the review and the user-given star rating. Features based on frequency (gap between rare and common words), written spoken gap (in terms of difference between usage), synonyms (based on the difference in frequency of synonyms) and ambiguity (number of words with many synonyms) were used by BIBREF3 for sarcasm detection in tweets. BIBREF9 proposed the use of implicit incongruity and explicit incongruity based features along with lexical and pragmatic features, such as emoticons and punctuation marks. Their method is very much similar to the method proposed by BIBREF5 except BIBREF9 used explicit incongruity features. Their method outperforms the approach by BIBREF5 on two datasets.\n BIBREF8 compared the performance with different language-independent features and pre-processing techniques for classifying text as sarcastic and non-sarcastic. The comparison was done over three Twitter dataset in two different languages, two of these in English with a balanced and an imbalanced distribution and the third one in Czech. The feature set included n-grams, word-shape patterns, pointedness and punctuation-based features.\nIn this work, we use features extracted from a deep CNN for sarcasm detection. Some of the key differences between the proposed approach and existing methods include the use of a relatively smaller feature set, automatic feature extraction, the use of deep networks, and the adoption of pre-trained NLP models.\nAn early work in this field was done by (Tsur et al., 2010) on a dataset of 6,600 manually annotated Amazon reviews using a kNN-classifier over punctuation-based and pattern-based features, i.e., ordered sequence of high frequency words.",

We propose Human-And-Model-in-the-Loop Entailment Training (HAMLET), a training procedure to automatically mitigate problems with current dataset collection procedures (see Figure FIGREF1).\nIn our setup, our starting point is a base model, trained on NLI data. Rather than employing automated adversarial methods, here the model's “adversary” is a human annotator. Given a context (also often called a “premise” in NLI), and a desired target label, we ask the human writer to provide a hypothesis that fools the model into misclassifying the label. One can think of the writer as a “white hat” hacker, trying to identify vulnerabilities in the system. For each human-generated example that is misclassified, we also ask the writer to provide a reason why they believe it was misclassified.\nFor examples that the model misclassified, it is necessary to verify that they are actually correct —i.e., that the given context-hypothesis pairs genuinely have their specified target label. The best way to do this is to have them checked by another human. Hence, we provide the example to human verifiers. If two human verifiers agree with the writer, the example is considered a good example. If they disagree, we ask a third human verifier to break the tie. If there is still disagreement between the writer and the verifiers, the example is discarded. Occasionally, verifiers will overrule the original label of the writer.\nOnce data collection for the current round is finished, we construct a new training set from the collected data, with accompanying development and test sets. While the training set includes correctly classified examples, the development and tests sets are built solely from them. The test set was further restricted so as to: 1) include pairs from “exclusive” annotators that are never included in the training data; and 2) be balanced by label classes (and genres, where applicable). We subsequently train a new model on this and other existing data, and repeat the procedure three times.\nIn our setup, our starting point is a base model, trained on NLI data.",

        "question": "Based on the following passage what are positive and conventional current?",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

I have divided these descriptions into two classes: linguistic bias and unwarranted inferences. The former corresponds to the annotators' choice of words when confronted with an image that may or may not match their stereotypical expectancies. The latter corresponds to the tendency of annotators to go beyond what the physical data can tell us, and expand their descriptions based on their past experiences and knowledge of the world. Acknowledging these phenomena is important, because on the one hand it helps us think about what is learnable from the data, and on the other hand it serves as a warning: if we train and evaluate language models on this data, we are effectively teaching them to be biased.\nI have also looked at methods to detect stereotype-driven descriptions, but due to the richness of language it is difficult to find an automated measure. Depending on whether your goal is production or interpretation, it may either be useful to suppress or to emphasize biases in human language. Finally, I have discussed stereotyping behavior as the addition of a contextual layer on top of a more basic description.

        "evidence": "Natural text generation, as a key task in NLP, has been advanced substantially thanks to the flourish of neural models BIBREF0 , BIBREF1 . Typical frameworks such as sequence-to-sequence (seq2seq) have been applied to various generation tasks, including machine translation BIBREF2 and dialogue generation BIBREF3 . The standard paradigm to train such neural models is maximum likelihood estimation (MLE), which maximizes the log-likelihood of observing each word in the text given the ground-truth proceeding context BIBREF4 .\nAlthough widely used, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 : during test, the model sequentially predicts the next word conditioned on its previous generated words while during training conditioned on ground-truth words. To tackle this problem, generative adversarial networks (GAN) with reinforcement learning (RL) training approaches have been introduced to text generation tasks BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , where the discriminator is trained to distinguish real and generated text samples to provide reward signals for the generator, and the generator is optimized via policy gradient BIBREF7 .\nHowever, recent studies have shown that potential issues of training GANs on discrete data are more severe than exposure bias BIBREF14 , BIBREF15 . One of the fundamental issues when generating discrete text samples with GANs is training instability. Updating the generator with policy gradient always leads to an unstable training process because it's difficult for the generator to derive positive and stable reward signals from the discriminator even with careful pre-training BIBREF8 . As a result, the generator gets lost due to the high variance of reward signals and the training process may finally collapse BIBREF16 .\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation. At each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples. Then, inspired by reward augmented maximum likelihood (RAML) BIBREF17 , the generator is updated on the samples acquired from a stationary distribution with maximum likelihood estimation (MLE), weighted by the discriminator's rewards. This stationary distribution is designed to guarantee that training samples are surrounding the real data, thus the exploration space of our generator is indeed restricted by the MLE training objective, resulting in more stable training. Compared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient. Our contributions are mainly as follows:\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation.",

Each wooden stud is typically sixteen inches apart - center to center.  And each wooden stud is typically two inches in width.  Second step is to carefully measure the open space after you've cut the square.  Take your time and measure as close to the existing drywall as possible.  Take 4 measurements of 2 in length and 2 in width to ensure accuracy.  Cut that square from your replacement drywall.  Shave sides with sandpaper for tight fit.

        "answer": "Experimental setup and results.",
        "evidence": "Event detection on microblogging platforms such as Twitter aims to detect events preemptively. A main task in event detection is detecting events of predetermined types BIBREF0, such as concerts or controversial events based on microposts matching specific event descriptions. This task has extensive applications ranging from cyber security BIBREF1, BIBREF2 to political elections BIBREF3 or public health BIBREF4, BIBREF5. Due to the high ambiguity and inconsistency of the terms used in microposts, event detection is generally performed though statistical machine learning models, which require a labeled dataset for model training. Data labeling is, however, a long, laborious, and usually costly process. For the case of micropost classification, though positive labels can be collected (e.g., using specific hashtags, or event-related date-time information), there is no straightforward way to generate negative labels useful for model training. To tackle this lack of negative labels and the significant manual efforts in data labeling, BIBREF1 (BIBREF1, BIBREF3) introduced a weak supervision based learning approach, which uses only positively labeled data, accompanied by unlabeled examples by filtering microposts that contain a certain keyword indicative of the event type under consideration (e.g., `hack' for cyber security). Another key technique in this context is expectation regularization BIBREF6, BIBREF7, BIBREF1. Here, the estimated proportion of relevant microposts in an unlabeled dataset containing a keyword is given as a keyword-specific expectation. This expectation is used in the regularization term of the model's objective function to constrain the posterior distribution of the model predictions. By doing so, the model is trained with an expectation on its prediction for microposts that contain the keyword. Such a method, however, suffers from two key problems:\nDue to the unpredictability of event occurrences and the constantly changing dynamics of users' posting frequency BIBREF8, estimating the expectation associated with a keyword is a challenging task, even for domain experts;\nThe performance of the event detection model is constrained by the informativeness of the keyword used for model training. As of now, we lack a principled method for discovering new keywords and improve the model performance.\nTo address the above issues, we advocate a human-AI loop approach for discovering informative keywords and estimating their expectations reliably. Our approach iteratively leverages 1) crowd workers for estimating keyword-specific expectations, and 2) the disagreement between the model and the crowd for discovering new informative keywords. More specifically, at each iteration after we obtain a keyword-specific expectation from the crowd, we train the model using expectation regularization and select those keyword-related microposts for which the model's prediction disagrees the most with the crowd's expectation; such microposts are then presented to the crowd to identify new keywords that best explain the disagreement. By doing so, our approach identifies new keywords which convey more relevant information with respect to existing ones, thus effectively boosting model performance. By exploiting the disagreement between the model and the crowd, our approach can make efficient use of the crowd, which is of critical importance in a human-in-the-loop context BIBREF9, BIBREF10. An additional advantage of our approach is that by obtaining new keywords that improve model performance over time, we are able to gain insight into how the model learns for specific event detection tasks. Such an advantage is particularly useful for event detection using complex models, e.g., deep neural networks, which are intrinsically hard to understand BIBREF11, BIBREF12. An additional challenge in involving crowd workers is that their contributions are not fully reliable BIBREF13. In the crowdsourcing literature, this problem is usually tackled with probabilistic latent variable models BIBREF14, BIBREF15, BIBREF16, which are used to perform truth inference by aggregating a redundant set of crowd contributions. Our human-AI loop approach improves the inference of keyword expectation by aggregating contributions not only from the crowd but also from the model. This, however, comes with its own challenge as the model's predictions are further dependent on the results of expectation inference, which is used for model training. To address this problem, we introduce a unified probabilistic model that seamlessly integrates expectation inference and model training, thereby allowing the former to benefit from the latter while resolving the inter-dependency between the two.\nTo the best of our knowledge, we are the first to propose a human-AI loop approach that iteratively improves machine learning models for event detection. In summary, our work makes the following key contributions:\nA novel human-AI loop approach for micropost event detection that jointly discovers informative keywords and estimates their expectation;\nA unified probabilistic model that infers keyword expectation and simultaneously performs model training;\nAn extensive empirical evaluation of our approach on multiple real-world datasets demonstrating that our approach significantly improves the state of the art by an average of 24.3% AUC.\nThe rest of this paper is organized as follows. First, we present our human-AI loop approach in Section SECREF2. Subsequently, we introduce our proposed probabilistic model in Section SECREF3. The experimental setup and results are presented in Section SECREF4. Finally, we briefly cover related work in Section SECREF5 before concluding our work in Section SECREF6.\nThe experimental setup and results are presented in Section 4.",

To optimize this altered loss, we choose SGD with learning rate 0.0001, momentum 0.9, and weight decay 0.0001. In addition to batch normalization, we also update convolutional layers except the final classification layer. As for SHOT, We execute the authors' open-sourced codebase with the same hyper-parameters for various architectures , initialization (from scratch and ImageNet pretrain), and domain shifts (train to val/test splits on VisDA-C).\nStage 2 (student) We experiment with two designs as students: 1) source-only, 2) contrastive learning. Specifically, we leverage some of off-the-shelf contrastive learning methods to initialize target-domain representation, such as MoCo v2, SimSiam SwAV, Barlow Twins. Compared to their training recipes on ImageNet, we have more epochs on VisDA-C val/test with the same batch size, learning rate, data augmentation, and model architecture, to make the training procedure longer with the smaller amount of images.\nStage 3 (teacher-student) By default, the whole knowledge distillation consists of three phases, where each phase has 10 epochs to train the student model with the hard pseudo label. The student would be reset to the contrastive model to avoid error accumulation at the beginning of every phase. The teacher would be replaced with the latest student before starting the next phase, so that the quality of pseudo-labeling could be improved gradually.

This information can be exploited in decision making processes but, to be useful, it should be transformed and presented in ways that make its intrinsic knowledge more readily intelligible. For that, we need efficient methods and tools that quickly extract useful information from unstructured text collections. Such demand can be observed, for instance, in Biology, where researchers, in order to be abreast of all developments, need to analyse new biomedical literature on a daily basis BIBREF2 . Another application is on fraud and corruption studies where the network information — the set of actors and their relationships — is implicitly stored in unstructured natural-language documents BIBREF3 . Hence, text mining and information extraction are required to pre-process the texts in order to extract the entities and the relations between them.\nInformation extraction is a challenging task mainly due to the ambiguous features of natural-language. Moreover, most tools need to be adapted to different human languages and to different domains BIBREF4 . In fact, the language of the processed texts is still the decisive factor when choosing among existing information extraction technologies. This is also true for the task of entity extraction (Named Entity Recognition - NER).\nFor several reasons, text mining tools are typically first developed for English and only afterwards extended to other languages. Thus, there are still relatively few text mining tools for Portuguese and even less that are freely accessible. In particular, for the named entities recognition task in Portuguese texts, we find three extractors available: Alchemy, Zemanta and Rembrandt BIBREF5 . We also find some studies where the measures ( INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ) for those extractors are computed and compared BIBREF6 , but their comparative effectiveness remains domain and final purpose dependent.\nIn this work, we present PAMPO (PAttern Matching and POs tagging based algorithm for NER), a new method to automatically extract named entities from unstructured texts, applicable to the Portuguese language but potentially adaptable to other languages as well. The method relies on flexible pattern matching, part-of-speech tagging and lexical-based rules. All steps are implemented using free software and taking advantage of various existing packages.\nThe process has been developed using as case-study a specific book written in Portuguese, but it has since been used in other applications and successfully tested in different text collections. In this paper, we describe the evaluation procedures on independent textual collections, and produce a comparative study of PAMPO with other existing tools for NER.\nIn this work, we present PAMPO (PAttern Matching and POs tagging based algorithm for NER), a new method to automatically extract named entities from unstructured texts, applicable to the Portuguese language but potentially adaptable to other languages as well.",

        "evidence": "As explained in the introduction, the overarching aim of this project is to investigate in how far information conveyed in social media posts can complement more traditional research methods in clinical psychology to get insights into the recovery experience of individuals with a BD diagnosis. Therefore, we will first conduct a systematic literature review of qualitative evidence to establish a solid base of what is already known about personal recovery experiences in BD for the subsequent social media studies.\nOur research questions, which regard the experiences of different populations, lend themselves to several subprojects. First, we will collect and analyse English-language data from westerners. Then, we will address ethnically diverse English-speaking populations and finally multilingual accounts. This has the advantage that we can build data processing and methodological workflows along an increase in complexity of the data collection and analysis throughout the project.\nIn each project phase, we will employ a mixed-methods approach to combine the advantages of quantitative and qualitative methods BIBREF52 , BIBREF53 , which is established in mental health research BIBREF54 , BIBREF55 , BIBREF56 , BIBREF57 and specifically recommended to investigate personal recovery BIBREF58 . Quantitative methods are suitable to study observable behaviour such as language and yield more generalisable results by taking into account large samples. However, they fall short of capturing the subjective, idiosyncratic meaning of socially constructed reality, which is important when studying individuals' recovery experience BIBREF59 , BIBREF22 , BIBREF23 , BIBREF60 . Therefore, we will apply an explanatory sequential research design BIBREF53 , starting with statistical analysis of the full dataset followed by a manual investigation of fewer examples, similar to `distant reading' BIBREF61 in digital humanities.\nSince previous research mainly employed (semi-)structured interviews and we do not expect to necessarily find the same aspects emphasised in unstructured settings, even less so when looking at a more diverse and non-English speaking population, we will not derive hypotheses from existing recovery models for testing on the online data. Instead, we will start off with exploratory quantitative research using comparative analysis tools such as Wmatrix BIBREF62 to uncover important linguistic features, e.g., on keywords and key concepts that occur with unexpected frequency in our collected datasets relative to reference corpora. The underlying assumption is that keywords and key concepts are indicative of certain aspects of personal recovery, such as those specified in the CHIME model BIBREF24 , other previous research BIBREF22 , BIBREF23 , BIBREF60 , or novel ones. Comparing online sources with transcripts of structured interviews or subcorpora originating from different cultural backgrounds might uncover aspects that were not prominently represented in the accounts studied in prior research.\nA specific challenge will be to narrow down the data to parts relevant for personal recovery, since there is no control over the discussed topics compared to structured interviews. To investigate how individuals discuss personal recovery online and what (potentially unrecorded) aspects they associate with it, without a priori narrowing down the search-space to specific known keywords seems like a chicken-and-egg problem. We propose to address this challenge by an iterative approach similar to the one taken in a corpus linguistic study of cancer metaphors BIBREF63 . Drawing on results from previous qualitative research BIBREF24 , BIBREF23 , we will compile an initial dictionary of recovery-related terms. Next, we will examine a small portion of the dataset manually, which will be partly randomly sampled and partly selected to contain recovery-related terms. Based on this, we will be able to expand the dictionary and additionally automatically annotate semantic concepts of the identified relevant text passages using a semantic tagging approach such as the UCREL Semantic Analysis System (USAS) BIBREF64 . Crucially for the multilingual aspect of the project, USAS can tag semantic categories in eight languages BIBREF8 . Then, semantic tagging will be applied to the full corpus to retrieve all text passages mentioning relevant concepts. Furthermore, distributional semantics methods BIBREF65 , BIBREF66 can be used to find terms that frequently co-occur with words from our keyword dictionary. Occurrences of the identified keywords or concepts can be quantified in the full corpus to identify the importance of the related personal recovery aspects.\nLinguistic Inquiry and Word Count (LIWC) BIBREF67 is a frequently used tool in social-science text analysis to analyse emotional and cognitive components of texts and derive features for classification models BIBREF47 , BIBREF46 , BIBREF68 , BIBREF69 . LIWC counts target words organised in a manually constructed hierarchical dictionary without contextual disambiguation in the texts under analysis and has been psychometrically validated and developed for English exclusively. While translations for several languages exist, e.g., Dutch BIBREF9 , and it is questionable to what extent LIWC concepts can be transferred to other languages and cultures by mere translation. We therefore aim to apply and develop methods that require less manual labour and are applicable to many languages and cultures. One option constitute unsupervised methods, such as topic modelling, which has been applied to explore cultural differences in mental-health related online data already BIBREF37 , BIBREF36 . The Differential Language Analysis ToolKit (DLATK) BIBREF70 facilitates social-scientific language analyses, including tools for preprocessing, such as emoticon-aware tokenisers, filtering according to meta data, and analysis, e.g. via robust topic modelling methods.\nFurthermore, emotion and sentiment analysis constitute useful tools to investigate the emotions involved in talking about recovery and identify factors that facilitate or hinder it. There are many annotated datasets to train supervised classifiers BIBREF71 , BIBREF3 for these actively researched NLP tasks. Machine learning methods were found to usually outperform rule-based approaches based on look-ups in dictionaries such as LIWC. Again, most annotated resources are English, but state of the art approaches based on multilingual embeddings allow transferring models between languages BIBREF4 .\nLinguistic Inquiry and Word Count (LIWC) (Pennebaker et al., 2015) is a frequently used tool in social-science text analysis to analyse emotional and cognitive components of texts and derive features for classification models (Cohan et al., 2018; Sekulic et al. ´ , 2018; Tackman et al., 2018; Wang and Jurgens, 2018).",

Arab-tweet is a tweet dataset of 11 Arabic regions from 17 different countries. For each region, data from 100 Twitter users were crawled. Users needed to have posted at least 2,000 and were selected based on an initial list of seed words characteristic of each region. The seed list included words such as <برشة> /barsha/ ‘many’ for Tunisian Arabic and <وايد> /wayed/ ‘many’ for Gulf Arabic. BIBREF19 employed human annotators to verify that users do belong to each respective region. Annotators also assigned gender labels from the set male, female and age group labels from the set under-25, 25-to34, above-35 at the user-level, which in turn is assigned at tweet level. Tweets with less than 3 words and re-tweets were removed. Refer to BIBREF19 for details about how annotation was carried out. We provide a description of the data in Table TABREF10. Table TABREF10 also provides class breakdown across our splits.We note that BIBREF19 do not report classification models exploiting the data.\nUBC Twitter Gender Dataset. We also develop an in-house Twitter dataset for gender. We manually labeled 1,989 users from each of the 21 Arab countries. The data had 1,246 “male\", 528 “female\", and 215 unknown users. We remove the “unknown\" category and balance the dataset to have 528 from each of the two `male\" and “female\" categories. We ended with 69,509 tweets for `male\" and 67,511 tweets for “female\". We split the users into 80% TRAIN set (110,750 tweets for 845 users), 10% DEV set (14,158 tweets for 106 users), and 10% TEST set (12,112 tweets for 105 users). We, then, model this dataset with BERT-Base, Multilingual Cased model and evaluate on development and test sets. Table TABREF15 shows that fine-tuned model obtains 62.42% acc on DEV and 60.54% acc on TEST.\nThe dialect identification model in AraNet is based on our winning system in the MADAR shared task 2 BIBREF20 as described in BIBREF12. The corpus is divided into train, dev and test, and the organizers masked test set labels. We lost some tweets from training data when we crawled using tweet ids, ultimately acquiring 2,036 (TRAIN-A), 281 (DEV) and 466 (TEST). We also make use of the task 1 corpus (95,000 sentences BIBREF21). More specifically, we concatenate the task 1 data to the training data of task 2, to create TRAIN-B. Again, note that TEST labels were only released to participants after the official task evaluation. Table TABREF17 shows statistics of the data. We used tweets from 21 Arab countries as distributed by task organizers, except that we lost some tweets when we crawled using tweet ids. We had 2,036 (TRAIN-A), 281 (DEV) and 466 (TEST). For our experiments, we also make use of the task 1 corpus (95,000 sentences BIBREF21). More specifically, we concatenate the task 1 data to the training data of task 2, to create TRAIN-B. Note that both DEV and TEST across our experiments are exclusively the data released in task 2, as described above. TEST labels were only released to participants after the official task evaluation. Table TABREF17 shows statistics of the data. More information about the data is in BIBREF21. We use TRAIN-A to perform supervised modeling with BERT and TRAIN-B for self training, under various conditions. We refer the reader to BIBREF12 for more information about our different experimental settings on dialect id. We acquire our best results with self-training, with a classification accuracy of 49.39% and F1 score at 35.44. This is the winning system model in the MADAR shared task and we showed in BIBREF12 that our tweet-level predictions can be ported to user-level prediction. On user-level detection, our models perform superbly, with 77.40% acc and 71.70% F1 score on unseen MADAR blind test data.\nWe make use of two datasets, the LAMA-DINA dataset from BIBREF22, a Twitter dataset with a combination of gold labels from BIBREF23 and distant supervision labels. The tweets are labeled with the Plutchik 8 primary emotions from the set: {anger, anticipation, disgust, fear, joy, sadness, surprise, trust}. The distant supervision approach depends on use of seed phrases with the Arabic first person pronoun انا> (Eng. “I\") + a seed word expressing an emotion, e.g., فرحان> (Eng. “happy\"). The manually labeled part of the data comprises tweets carrying the seed phrases verified by human annotators $9,064$ tweets for inclusion of the respective emotion. The rest of the dataset is only labeled using distant supervision (LAMA-DIST) ($182,605$ tweets) . For more information about the dataset, readers are referred to BIBREF22. The data distribution over the emotion classes is in Table TABREF20. We combine LAMA+DINA and LAMA-DIST training set and refer to this new training set as LAMA-D2 (189,903 tweets). We fine-tune BERT-Based, Multilingual Cased on the LAMA-D2 and evaluate the model with same DEV and TEST sets from LAMA+DINA. On DEV set, the fine-tuned BERT model obtains 61.43% on accuracy and 58.83 on $F_1$ score. On TEST set, we acquire 62.38% acc and 60.32% $F_1$ score.\nWe use the dataset for irony identification on Arabic tweets released by IDAT@FIRE2019 shared-task BIBREF24. The shared task dataset contains 5,030 tweets related to different political issues and events in the Middle East taking place between 2011 and 2018. Tweets are collected using pre-defined keywords (i.e., targeted political figures or events) and the positive class involves ironic hashtags such as #sokhria, #tahakoum, and #maskhara (Arabic variants for “irony\"). Duplicates, retweets, and non-intelligible tweets are removed by organizers. Tweets involve both MSA as well as dialects at various degrees of granularity such as Egyptian, Gulf, and Levantine.\nWe collect 15 datasets related to sentiment analysis of Arabic, including MSA and dialects BIBREF25, BIBREF26, BIBREF27, BIBREF1, BIBREF28, BIBREF29, BIBREF30, BIBREF31, BIBREF32, BIBREF33, BIBREF34.

The award was launched in 1958; originally, the requirement for a Gold single was one million units sold and a Gold album represented $1 million in sales (at wholesale value, around a third of the list price). In 1975, the additional requirement of 500,000 units sold was added for Gold albums. Reflecting growth in record sales, the Platinum award was added in 1976, for albums able to sell one million units, and singles selling two million units. The Multi-Platinum award was introduced in 1984, signifying multiple Platinum levels of albums and singles. In 1989, the sales thresholds for singles were reduced to 500,000 for Gold and 1,000,000 for Platinum, reflecting a decrease in sales of singles. In 1992, RIAA began counting each disc in a multi-disc set as one unit toward certification.

It is cognate with the Standard Tibetan pulu, also meaning 'ball'.\n\nAlthough the exact origins of the game are not certain, many scholars suggest it most likely began as a simple game played by Iranic and Turkic equestrian nomads in Central Asia. An archaic variation of polo, regionally referred to as buzkashi or kokpar, is still played in parts of Central Asia. It was developed and formalised in Ancient Iran (Persia) as \"chovgan\" (čowgān), becoming a national sport played extensively by the nobility. Women played as well as men.

        "question": "What does the author sample from the insertion model?",
        "answer": "An input sequence on-policy.",
        "evidence": "Neural sequence models BIBREF0, BIBREF1 typically generate outputs in an autoregressive left-to-right manner. These models have been successfully applied to a range of task, for example machine translation BIBREF2. They often rely on an encoder that processes the source sequence, and a decoder that generates the output sequence conditioned on the output of the encoder. The decoder will typically generate the target sequence one token at a time, in an autoregressive left-to-right fashion.\nRecently, research in insertion-based non- or partially- autoregressive models has spiked BIBREF3, BIBREF4, BIBREF5, BIBREF6. These model are more flexible than their autoregressive counterparts. They can generate sequences in any order, and can benefit from parallel token generation. They can learn complex orderings (e.g., tree orderings) and may be more applicable to task like cloze question answering BIBREF6 and text simplification, where the order of generation is not naturally left to right, and the source sequence might not be fully observed. One recently proposed approach is the Insertion Transformer BIBREF3, where the target sequence is modelled with insertion-edits. As opposed to traditional sequence-to-sequence models, the Insertion Transformer can generate sequences in any arbitrary order, where left-to-right is a special case. Additionally, during inference, the model is endowed with parallel token generation capabilities. The Insertion Transformer can be trained to follow a soft balanced binary tree order, thus allowing the model to generate $n$ tokens in $O(\\log _2 n)$ iterations.\nIn this work we propose to generalize this insertion-based framework, we present a framework which emits both insertions and deletions. Our Insertion-Deletion Transformer consists of an insertion phase and a deletion phase that are executed iteratively. The insertion phase follows the typical insertion-based framework BIBREF3. However, in the deletion phase, we teach the model to do deletions with on-policy training. We sample an input sequence on-policy from the insertion model (with on-policy insertion errors), and teach the deletion model its appropriate deletions.\nThis insertion-deletion framework allows for flexible sequence generation, parallel token generation and text editing. In a conventional insertion-based model, if the model makes a mistake during generation, this cannot be undone. Introducing the deletion phase makes it possible to undo the mistakes made by the insertion model, since it is trained on the on-policy errors of the insertion phase. The deletion model extension also enables the framework to efficiently handle tasks like text simplification and style transfer by starting the decoding process from the original source sequence.\nA concurrent work was recently proposed, called the Levenshtein Transformer (LevT) BIBREF7. The LevT framework also generates sequences with insertion and deletion operations. Our approach has some important distinctions and can be seen as a simplified version, for both the architecture and the training algorithm. The training algorithm used in the LevT framework uses an expert policy. This expert policy requires dynamic programming to minimize Levenshtein distance between the current input and the target. This approach was also explored by BIBREF8, BIBREF9. Their learning algorithm arguably adds more complexity than needed over the simple on-policy method we propose. The LevT framework consists of three stages, first the number of tokens to be inserted is predicted, then the actual tokens are predicted, and finally the deletion actions are emitted. The extra classifier to predict the number of tokens needed to be inserted adds an additional Transformer pass to each generation step. In practice, it is also unclear whether the LevT exhibits speedups over an insertion-based model following a balanced binary tree order. In contrast, our Insertion-Deletion framework only has one insertion phase and one deletion phase, without the need to predict the number of tokens needed to be inserted. This greatly simplifies the model architecture, training procedure and inference runtime.\nAn alternative approach for text editing is proposed by BIBREF10, which they dub Deliberation Networks. This work also acknowledges the potential benefits from post-editing output sequences and proposes a two-phase decoding framework to facilitate this.\nIn this paper, we present the insertion-deletion framework as a proof of concept by applying it to two synthetic character-based translation tasks and showing it can significantly increase the BLEU score over the insertion-only framework.\nWe sample an input sequence on-policy from the insertion model (with on-policy insertion errors), and teach the deletion model its appropriate deletions.",

Twitch is operated by Twitch Interactive, a subsidiary of Amazon.com, Inc. It was introduced in June 2011 as a spin-off of the general-interest streaming platform Justin.tv. Content on the site can be viewed either live or via video on demand. The games shown on Twitch's current homepage are listed according to audience preference and include genres such as real-time strategy games (RTS), fighting games, racing games, and first-person shooters.\n\nThe popularity of Twitch eclipsed that of its general-interest counterpart. In October 2013, the website had 45 million unique viewers, and by February 2014, it was considered the fourth-largest source of peak Internet traffic in the United States. At the same time, Justin.tv's parent company was re-branded as Twitch Interactive to represent the shift in focus – Justin.tv was shut down in August 2014. That month, the service was acquired by Amazon for US$970 million, which later led to the introduction of synergies with the company's subscription service Amazon Prime. Twitch acquired Curse LLC in 2016, an operator of online video gaming communities and introduced means to purchase games through links on streams along with a program allowing streamers to receive commissions on the sales of games that they play.\n\nBy 2015, Twitch had more than 100 million viewers per month. In 2017, Twitch remained the leading live streaming video service for video games in the US, and had an advantage over YouTube Gaming, which shut down its standalone app in May 2019.

We participated in Task B of the challenge which is concerned with biomedical QA. More specifically, our system participated in Task B, Phase B: Given a question and gold-standard snippets (i.e., pieces of text that contain the answer(s) to the question), the system is asked to return a list of answer candidates.\nThe fifth BioASQ challenge is taking place at the time of writing. Five batches of 100 questions each were released every two weeks. Participating systems have 24 hours to submit their results. At the time of writing, all batches had been released.\nThe questions are categorized into different question types: factoid, list, summary and yes/no. Our work concentrates on answering factoid and list questions. For factoid questions, the system's responses are interpreted as a ranked list of answer candidates. They are evaluated using mean-reciprocal rank (MRR). For list questions, the system's responses are interpreted as a set of answers to the list question. Precision and recall are computed by comparing the given answers to the gold-standard answers. F1 score, i.e., the harmonic mean of precision and recall, is used as the official evaluation measure .\nMost existing biomedical QA systems employ a traditional QA pipeline, similar in structure to the baseline system by weissenborn2013answering. They consist of several discrete steps, e.g., named-entity recognition, question classification, and candidate answer scoring. These systems require a large amount of resources and feature engineering that is specific to the biomedical domain. For example, OAQA BIBREF1 , which has been very successful in last year's challenge, uses a biomedical parser, entity tagger and a thesaurus to retrieve synonyms.\nOur system, on the other hand, is based on a neural network QA architecture that is trained end-to-end on the target task. We build upon FastQA BIBREF2 , an extractive factoid QA system which achieves state-of-the-art results on QA benchmarks that provide large amounts of training data. For example, SQuAD BIBREF3 provides a dataset of $\\approx 100,000$ questions on Wikipedia articles. Our approach is to train FastQA (with some extensions) on the SQuAD dataset and then fine-tune the model parameters on the BioASQ training set.\nNote that by using an extractive QA network as our central component, we restrict our system's responses to substrings in the provided snippets. This also implies that the network will not be able to answer yes/no questions. We do, however, generalize the FastQA output layer in order to be able to answer list questions in addition to factoid questions.\nBioASQ is a semantic indexing, question answering (QA) and information extraction challenge.",

While NMT is generally more fluent than previous statistical systems, adequacy is still a major concern BIBREF4 : common mistakes include dropping source words and repeating words in the generated translation.\nPrevious work has attempted to mitigate this problem in various ways. BIBREF5 incorporate coverage and length penalties during beam search—a simple yet limited solution, since it only affects the scores of translation hypotheses that are already in the beam. Other approaches involve architectural changes: providing coverage vectors to track the attention history BIBREF6 , BIBREF7 , using gating architectures and adaptive attention to control the amount of source context provided BIBREF8 , BIBREF9 , or adding a reconstruction loss BIBREF10 . BIBREF11 also use the notion of fertility implicitly in their proposed model. Their “fertility conditioned decoder” uses a coverage vector and an “extract gate” which are incorporated in the decoding recurrent unit, increasing the number of parameters.\nIn this paper, we propose a different solution that does not change the overall architecture, but only the attention transformation. Namely, we replace the traditional softmax by other recently proposed transformations that either promote attention sparsity BIBREF12 or upper bound the amount of attention a word can receive BIBREF13 . The bounds are determined by the fertility values of the source words. While these transformations have given encouraging results in various NLP problems, they have never been applied to NMT, to the best of our knowledge. Furthermore, we combine these two ideas and propose a novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments. While being in-between soft and hard alignments (Figure FIGREF20 ), the constrained sparsemax transformation is end-to-end differentiable, hence amenable for training with gradient backpropagation.\nTo sum up, our contributions are as follows:\nIn this paper, we propose a different solution that does not change the overall architecture, but only the attention transformation.",

        "evidence": "The game involves using figures mounted on rotating bars to kick a ball into the opposing goal. Table football tables can vary in size, but a typical table is about 120 centimetres (3.9 ft) long and 61 centimetres (2.00 ft) wide. The table usually contains eight rows of foos men, which are plastic, metal, wooden, or sometimes carbon-fibre figures mounted on horizontal metal bars. Each team of one or two human players controls four rows of foos men, one row each for the goalkeeper, defenders, midfield and strikers. Players manipulate the rods to control the figures, using them to hold up, pass or 'kick' the ball. Games begin when the ball is served through a hole at the side of the table, or simply placed by hand at the feet of a figure in the centre of the table. A coin toss is usually used to determine which player or team serves first. If it is not the first match or if the ball gets out of play or if the ball suddenly stops out, then the team scored last would get the serve after he scores one. The term for when the ball leaves the table or gets stopped somewhere out of the men-like figures’ reach is dead ball. Expert players have been known to move balls at speeds up to 56 km/h (35 mph) in competition.\n\nThe rules prohibit \"over 360-degree shots\", or \"spinning\": using the palm of the hand to swiftly spin the bar all around, instead of using wrist strokes to kick the ball with a bar-mounted figure. Since the establishment of the International Table Soccer Federation (ITSF), the rules have become standardised in most international competitions. However, since January 2012, the annual World Championships and the World Cup have permitted two full 360-degree rotations.\n\nThe winner is determined when one team scores a predetermined number of goals, typically five, ten or eleven in competition.

There are some gaps between these methods and ours (as well as the baselines selected in our original draft). The main point and contribution of our work is to propose a novel graph representation learning method and generate interpretable latent variables to better represent the common properties of directed graphs, including link reciprocity, degree heterogeneity and community structure. These learned node representations are readily to be applied for multiple downstream tasks, including but not limited to link prediction and community detection. The experiments in our paper are conducted for the purpose of testing whether these learned representations are able to capture the interpreted graph properties. For example, the link prediction task verifies the ability to represent link reciprocity of directed graphs, and the community detection task verifies the ability for modeling clustering effects.\nWe sincerely hope the reviewer to recosider on this point since our work is not acturally aiming for link prediction.

These are four conjunctively written Nguni languages (zul, xho, nbl, ssw), Afrikaans (afr) and English (eng), three disjunctively written Sotho languages (nso, sot, tsn), as well as tshiVenda (ven) and Xitsonga (tso). The Nguni languages are similar to each other and harder to distinguish. The same is true of the Sotho languages.\nThis paper presents a hierarchical naive Bayesian and lexicon based classifier for LID of short pieces of text of 15-20 characters long. The algorithm is evaluated against recent approaches using existing test sets from previous works on South African languages as well as the Discriminating between Similar Languages (DSL) 2015 and 2017 shared tasks.\nSection SECREF2 reviews existing works on the topic and summarises the remaining research problems. Section SECREF3 of the paper discusses the proposed algorithm and Section SECREF4 presents comparative results.\nThe algorithm is evaluated against recent approaches using existing test sets from previous works on South African languages as well as the Discriminating between Similar Languages (DSL) 2015 and 2017 shared tasks.",

In computer vision and natural language processing tasks, inputs or labels often come in with different shapes, such as images with a varying number of objects and sentences of different lengths. Thus, the data API provides a collection of utilities to sample inputs or labels then transform them into mini-batches to be efficiently computed. Besides, users can access a wide range of popular data sets via the data API, including (but are not limited to) ImageNet of image classification, VOC of object detection, COCO of instance segmentation, SQuAD of question answering, and SST of sentiment analysis.\nTo elucidate how the modular API facilitates efficient implementation, let us take the data API of GluonCV/NLP as an example, which is used to build efficient data pipelines with popular benchmark data sets or those supplied by users.",

The Buccaneers compete in the National Football League (NFL) as a member club of the league's National Football Conference (NFC) South division. The club joined the NFL in 1976 as an expansion team, along with the Seattle Seahawks, and played its first season in the American Football Conference (AFC) West division. Prior to the 1977 season, Tampa Bay switched conferences and divisions with Seattle, becoming a member of the NFC Central division. As a result of the league's realignment prior to the 2002 season, the Buccaneers joined three former NFC West teams to form the NFC South. The club is owned by the Glazer family and plays its home games at Raymond James Stadium in Tampa.\n\nThe Buccaneers have won two Super Bowl championships and, along with the Baltimore Ravens, are the only two NFL franchises who are undefeated in multiple Super Bowl appearances. They were regarded as a perennial losing franchise for most of their first two decades due to suffering 26 consecutive losses in their first two seasons (including a winless inaugural season) and 14 consecutive losing seasons from 1983 to 1996. Despite these early struggles, Tampa Bay is the first post-merger expansion team to clinch a division title, win a playoff game, and host a conference championship; feats they accomplished by their fourth season in 1979. The team's image improved by the time of their first championship in 2002, also the first for a franchise built after the merger, but they would not win another playoff game until their second Super Bowl championship season in 2020.

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nWe justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.",

        "evidence": "* Equal contribution. Listing order is random.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma. More concretely, consider the English sentence: The bulls are running in Pamplona. A lemmatizer will seek to map each word to a form you may find in a dictionary—for instance, mapping running to run. This linguistic normalization is important in several downstream NLP applications, especially for highly inflected languages. Lemmatization has previously been shown to improve recall for information retrieval BIBREF0 , BIBREF1 , to aid machine translation BIBREF2 , BIBREF3 and is a core part of modern parsing systems BIBREF4 , BIBREF5 .\nHowever, the task is quite nuanced as the proper choice of the lemma is context dependent. For instance, in the sentence A running of the bulls took place in Pamplona, the word running is its own lemma, since, here, running is a noun rather than an inflected verb. Several counter-examples exist to this trend, as discussed in depth in haspelmath2013understanding. Thus, a good lemmatizer must make use of some representation of each word's sentential context. The research question in this work is, then, how do we design a lemmatization model that best extracts the morpho-syntax from the sentential context?\nRecent work BIBREF7 has presented a system that directly summarizes the sentential context using a recurrent neural network to decide how to lemmatize. As N18-1126's system currently achieves state-of-the-art results, it must implicitly learn a contextual representation that encodes the necessary morpho-syntax, as such knowledge is requisite for the task. We contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize. Indeed, to this end, we introduce a joint model for the introduction of morphology into a neural lemmatizer. A key feature of our model is its simplicity: Our contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model. However, despite the model's simplicity, it still achieves a significant improvement over the state of the art on our target task: lemmatization.\nExperimentally, our contributions are threefold. First, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora BIBREF8 . Second, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization. Finally, we provide a detailed error analysis indicating when and why morphological analysis helps lemmatization. We offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.\nOur system and pre-trained models on all languages in the latest version of the UD corpora are released at https://sigmorphon.github.io/sharedtasks/2019/task2/.\nWe offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.",

We modeled the relationship between word count and the two metrics of user engagement (overall rating, mean number of turns) in separate linear regressions.\nResults showed that users who, on average, produced utterances with more words gave significantly higher ratings ($\\beta $=0.01, SE=0.002, t=4.79, p$<$0.001)(see Figure 2) and engaged with Gunrock for significantly greater number of turns ($\\beta $=1.85, SE=0.05, t=35.58, p$<$0.001) (see Figure 2).

        "evidence": "Language models can be optimized to recognize syntax and semantics with great accuracy BIBREF0. However, the output generated can be repetitive and generic leading to monotonous or uninteresting responses (e.g “I don't know”) regardless of the input BIBREF1. While application of attention BIBREF2, BIBREF3 and advanced decoding mechanisms like beam search and variation sampling BIBREF4 have shown improvements, it does not solve the underlying problem. In creative text generation, the objective is not strongly bound to the ground truth—instead the objective is to generate diverse, unique or original samples. We attempt to do this through a discriminator which can give feedback to the generative model through a cost function that encourages sampling of creative tokens. The contributions of this paper are in the usage of a GAN framework to generate creative pieces of writing. Our experiments suggest that generative text models, while very good at encapsulating semantic, syntactic and domain information, perform better with external feedback from a discriminator for fine-tuning objectiveless decoding tasks like that of creative text. We show this by evaluating our model on three very different creative datasets containing poetry, metaphors and lyrics.\nPrevious work on handling the shortcomings of MLE include length-normalizing sentence probability BIBREF5, future cost estimation BIBREF6, diversity-boosting objective function BIBREF7, BIBREF1 or penalizing repeating tokens BIBREF8. When it comes to poetry generation using generative text models, Zhang and Lapata BIBREF9, Yi et al. BIBREF10 and Wang et al. BIBREF11 use language modeling to generate Chinese poems. However, none of these methods provide feedback on the quality of the generated sample and hence, do not address the qualitative objective required for creative decoding. For the task of text generation, MaskGAN BIBREF12 uses a Reinforcement Learning signal from the discriminator, FMD-GAN BIBREF13 uses an optimal transport mechanism as an objective function. GumbelGAN BIBREF14 uses Gumbel-Softmax distribution that replaces the non-differentiable sample from a categorical distribution with a differentiable sample to propagate stronger gradients. Li et al.

Treatment is usually based on whether clinical features of asthma or COPD predominate. Inhaled corticosteroids are the primary treatment in those with ACOS. Inhaled corticosteroids (ICS) should be continued in those with asthma who develop decreased airway responsiveness to bronchodilators consistent with ACO. Therapy can be escalated to include a long acting beta-agonist (LABA) and inhaled steroid combination (ICS-LABA) or by adding on a long-acting anti-muscarinic inhaler (LAMA), known as triple therapy, in those with more severe or resistant disease.\n\nMonoclonal antibodies targeting type 2 inflammation (which is predominant in asthma) have been used to treat severe asthma, and may also be used in severe cases of ACO. These monoclonal antibodies include omalizumab (an Anti-IgE antibody), mepolizumab (an anti-IL-5 antibody) and benralizumab (an anti-IL-5 receptor α antibody). People with ACOS and eosinophilia have a better response to ICS; with fewer exacerbations and hospitalizations seen in ACOS treated with long term ICS.

        "evidence": "Performance appraisal (PA) is an important HR process, particularly for modern organizations that crucially depend on the skills and expertise of their workforce. The PA process enables an organization to periodically measure and evaluate every employee's performance. It also provides a mechanism to link the goals established by the organization to its each employee's day-to-day activities and performance. Design and analysis of PA processes is a lively area of research within the HR community BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 .\nThe PA process in any modern organization is nowadays implemented and tracked through an IT system (the PA system) that records the interactions that happen in various steps. Availability of this data in a computer-readable database opens up opportunities to analyze it using automated statistical, data-mining and text-mining techniques, to generate novel and actionable insights / patterns and to help in improving the quality and effectiveness of the PA process BIBREF4 , BIBREF5 , BIBREF6 . Automated analysis of large-scale PA data is now facilitated by technological and algorithmic advances, and is becoming essential for large organizations containing thousands of geographically distributed employees handling a wide variety of roles and tasks.\nA typical PA process involves purposeful multi-step multi-modal communication between employees, their supervisors and their peers. In most PA processes, the communication includes the following steps: (i) in self-appraisal, an employee records his/her achievements, activities, tasks handled etc.; (ii) in supervisor assessment, the supervisor provides the criticism, evaluation and suggestions for improvement of performance etc.; and (iii) in peer feedback (aka INLINEFORM0 view), the peers of the employee provide their feedback. There are several business questions that managers are interested in. Examples:\nIn this paper, we develop text mining techniques that can automatically produce answers to these questions. Since the intended users are HR executives, ideally, the techniques should work with minimum training data and experimentation with parameter setting. These techniques have been implemented and are being used in a PA system in a large multi-national IT company.\nThe rest of the paper is organized as follows. Section SECREF2 summarizes related work. Section SECREF3 summarizes the PA dataset used in this paper. Section SECREF4 applies sentence classification algorithms to automatically discover three important classes of sentences in the PA corpus viz., sentences that discuss strengths, weaknesses of employees and contain suggestions for improving her performance. Section SECREF5 considers the problem of mapping the actual targets mentioned in strengths, weaknesses and suggestions to a fixed set of attributes. In Section SECREF6 , we discuss how the feedback from peers for a particular employee can be summarized. In Section SECREF7 we draw conclusions and identify some further work.\nPerformance appraisal (PA) is an important HR process, particularly for modern organizations that crucially depend on the skills and expertise of their workforce.

        "evidence": "As a starting point for our pilots, we made use of texts from the InScript corpus BIBREF10 , which provides stories centered around everyday situations (see Section SECREF7 ). We conducted three different pilot studies to determine the best way of collecting questions that require inference over commonsense knowledge:\nThe most intuitive way of collecting reading comprehension questions is to show texts to workers and let them formulate questions and answers on the texts, which is what we tried internally in a first pilot. Since our focus is to provide an evaluation framework for inference over commonsense knowledge, we manually assessed the number of questions that indeed require common sense knowledge. We found too many questions and answers collected in this manner to be lexically close to the text.\nIn a second pilot, we investigated the option to take the questions collected for one text and show them as questions for another text of the same scenario. While this method resulted in a larger number of questions that required inference, we found the majority of questions to not make sense at all when paired with another text. Many questions were specific to a text (and not to a scenario), requiring details that could not be answered from other texts. Since the two previous pilot setups resulted in questions that centered around the texts themselves, we decided for a third pilot to not show workers any specific texts at all. Instead, we asked for questions that centered around a specific script scenario (e.g. eating in a restaurant). We found this mode of collection to result in questions that have the right level of specificity for our purposes: namely, questions that are related to a scenario and that can be answered from different texts (about that scenario), but for which a text does not need to provide the answer explicitly.\nThe next section will describe the mode of collection chosen for the final dataset, based on the third pilot, in more detail.\nAs a starting point for our pilots, we made use of texts from the InScript corpus (Modi et al., 2016), which provides stories centered around everyday situations (see Section 2.2.2.).

She has worked at this specific cafe for over 5 years and has learned to love the job, and has grown close to her coworkers and regular customers. While Mary is a specialist in preparing many types of coffee and tea drinks, her favorite of all time was to make the latte. One morning around 8:00 am, a regular customer named Eric came into the cafe. Eric usually orders a latte every morning around the same time and Mary really enjoys preparing his drink. When Mary saw Eric walk in, she started preparing his drink without even asking what he would order. First Mary greeted Eric and engaged in some small talk, conversing about the seasonally warm weather we were having. While simultaneously having this conversation, Mary was in process of making the coffee drink. Mary first ground 18g of espresso roast coffee on a fine grind setting. Once the coffee was ground, she filled the portafilter with the ground coffee. Once the portafilter was full of coffee, Mary tamped the coffee with a tamper, using about 30 pounds of force. When the portafilter was ready, she fixed it upon the espresso machine. Next Mary filled a milk pitcher with 12 ounces of whole milk. She then took the pitcher, held it to the steam wand, and started steaming the milk. For the first 5 seconds, she held the milk just below the surface of the milk to aerate the milk, and then moved the pitcher up so the steam wand was fully emerged. While the milk was steaming, Mary pressed the espresso button on the machine to start the pouring of the espresso into the two shot glasses. Mary was an expert in doing multiple latte making tasks simultaneously. As the milk finished steaming, she removed the pitcher, wiped down the steam wand, and set the milk aside. At that time, the espresso shots were done, and Mary poured the espresso from the shot glasses into the 16 oz paper cup. She then took the steamed milk and poured it over the espresso shots in the cup. She poured the milk in a specific way that would create latte art, this time she made a little heart out of the milk and foam. Once all the milk was poured, she put a cup on the coffee and handed the coffee over to Eric, who she was still having a conversation with. Once he received the coffee, Eric scanned his gift card on the computer which Mary had prepared for payment for the latte. After Eric was done paying, he took a sip of the drink and complimented Mary for another excellently prepared latte. After taking his sip, Eric then left the store, and got into this car, and drove away. It was moments like this every morning that reminded Mary why she loves this job so much, and looked forward to helping more customers for the remainder of her shift that morning.",

        "question": "Given this text about gradient descent, what is gradient descent, and who invented it?",
        "evidence": "In mathematics, gradient descent (also often called steepest descent) is a first-order iterative optimization algorithm for finding a local minimum of a differentiable function. The idea is to take repeated steps in the opposite direction of the gradient (or approximate gradient) of the function at the current point, because this is the direction of steepest descent. Conversely, stepping in the direction of the gradient will lead to a local maximum of that function; the procedure is then known as gradient ascent.\n\nGradient descent is generally attributed to Augustin-Louis Cauchy, who first suggested it in 1847. Jacques Hadamard independently proposed a similar method in 1907. Its convergence properties for non-linear optimization problems were first studied by Haskell Curry in 1944, with the method becoming increasingly well-studied and used in the following decades.",

        "evidence": "Given the large collections of unstructured and semi-structured data available on the web, there is a crucial need to enable quick and efficient access to the knowledge content within them. Traditionally, the field of information extraction has focused on extracting such knowledge from unstructured text documents, such as job postings, scientific papers, news articles, and emails. However, the content on the web increasingly contains more varied types of data, including semi-structured web pages, tables that do not adhere to any schema, photographs, videos, and audio. Given a query by a user, the appropriate information may appear in any of these different modes, and thus there's a crucial need for methods to construct knowledge bases from different types of data, and more importantly, combine the evidence in order to extract the correct answer.\nMotivated by this goal, we introduce the task of multimodal attribute extraction. Provided contextual information about an entity, in the form of any of the modes described above, along with an attribute query, the goal is to extract the corresponding value for that attribute. While attribute extraction on the domain of text has been well-studied BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , to our knowledge this is the first time attribute extraction using a combination of multiple modes of data has been considered. This introduces additional challenges to the problem, since a multimodal attribute extractor needs to be able to return values provided any kind of evidence, whereas modern attribute extractors treat attribute extraction as a tagging problem and thus only work when attributes occur as a substring of text.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API. The collection of items is diverse and includes categories such as electronic products, jewelry, clothing, vehicles, and real estate. For each item, we provide a textual product description, collection of images, and open-schema table of attribute-value pairs (see Figure 1 for an example). The provided attribute-value pairs only provide a very weak source of supervision; where the value might appear in the context is not known, and further, it is not even guaranteed that the value can be extracted from the provided evidence. In all, there are over 4 million images and 7.6 million attribute-value pairs. By releasing such a large dataset, we hope to drive progress on this task similar to how the Penn Treebank BIBREF5 , SQuAD BIBREF6 , and Imagenet BIBREF7 have driven progress on syntactic parsing, question answering, and object recognition, respectively.\nTo asses the difficulty of the task and the dataset, we first conduct a human evaluation study using Mechanical Turk that demonstrates that all available modes of information are useful for detecting values. We also train and provide results for a variety of machine learning models on the dataset. We observe that a simple most-common value classifier, which always predicts the most-common value for a given attribute, provides a very difficult baseline for more complicated models to beat (33% accuracy). In our current experiments, we are unable to train an image-only classifier that can outperform this simple model, despite using modern neural architectures such as VGG-16 BIBREF8 and Google's Inception-v3 BIBREF9 . However, we are able to obtain significantly better performance using a text-only classifier (59% accuracy). We hope to improve and obtain more accurate models in further research.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API.",

In these two tables, we use bold values to denote the highest accuracy among all methods and use the underline values to indicate our SRAT variants which achieve the highest accuracy among their corresponding baseline methods utilizing the same loss function for making predictions. Due to the limited space, we report the performance comparison on other imbalanced datasets created from CIFAR10, CIFAR100 and SVHN datasets in Appendix A.6.\nFrom Table, we can make the following observations. First, compared to baseline methods, our SRAT method obtains improved performance in terms of both overall standard & robust accuracy under almost all imbalanced settings. More importantly, SRAT makes significant improvements on those under-represented classes, especially under the extremely imbalanced settings. For the CIFAR10 Step-100 dataset, our SRAT-Focal method improves the standard accuracy on under-represented classes from 21.81% achieved by the best baseline method utilizing Focal loss to 51.83% and robust accuracy from 3.24% to 15.89%. These results demonstrate that our SRAT method is able to obtain more robustness under imbalanced settings. Second, the performance gap among three SRAT variants are mainly caused by the gap between the loss functions in these methods. As shown in these two tables, DRCB-LDAM typically performs better than DRCE-CE and DRCB-Focal, and similarly, SRAT-LDAM outperforms SRAT-CE and SRAT-Focal under the same settings.\nIn these two tables, we use bold values to denote the highest accuracy among all methods and use the underline values to indicate our SRAT variants which achieve the highest accuracy among their\ncorresponding baseline methods utilizing the same loss function for making predictions.",

        "evidence": "",
        "answer": "Suppose you wish to camp anywhere in the park other than in developed campgrounds on the North or South Rim. In that case, you must obtain a permit from the Backcountry Information Center. Camping sites are limited in the Grand Canyon, and spots are issued four months before a given month. E.g., For January, permit applications should be submitted between Aug 20 and Sep 1 to be considered \"earliest requested.\"\nFor requests received during the Earliest Consideration period, the day received does not matter; all Earliest Consideration requests received during this span of dates are treated the same. It may take Rangers up to three weeks to process all Earliest Consideration requests.\nSubsequent Requests: Once all Earliest Consideration requests are processed, Rangers will begin processing written requests received on subsequent dates. These Subsequent Requests are kept and considered in the order received. Submissions will be accepted as late as two weeks before a hike start date.\n \nIf your permit request is selected, you must diligently plan your trip. You will need to carry everything you need for the duration of your journey with you except for water which is few and far between. Know where the water sources are on your route and carry filtration devices, water purification equipment, and backup equipment. The hotter the trip, the more water you will require. Have a plan for where the necessary water will be on your route, and double-check with the park service ahead of time that water is still there. Dehydration is the number one reason for rescue and death in the canyon. Some springs dry up in the summer months.\n \nTravel as light as possible; you must pack everything you bring into the canyon, including used toilet paper.    Plan each meal, knowing how much calories and water you consume based on your planned exertion level. Calorie and water requirements also change based on temperature (the hotter the day, the more water and food you will need). Also, make sure you have the appropriate gear based on temperatures. It is approximately 20 degrees cooler at the top of the canyon than at the bottom because there is a 5000 feet vertical difference at the South Rim and 6000 at the North Rim. Ensure your footwear is \"broken in\", and carry first-aid kits with particular attention to foot care, such as blister pads and moleskin.   \n \nStart with shorter, more leisurely trips; if you like them, move up to more adventurous multi-day trips. Plan on rest days when you can enjoy the majestic scenery of one of the world's natural wonders. Above all, enjoy the canyon; it's a magical place 6 million years in the making that exposes geology over 4 billion years old.",

Leonard is a nerd who loves video games, comic books, and Dungeons & Dragons. Leonard is the straight man of the series, sharing an apartment in Pasadena, CA, with Sheldon Cooper. Leonard is smitten with his new neighbor Penny when they first meet, and they eventually marry.\n\nJim Parsons as Sheldon Cooper: Originally from Galveston, Texas, Sheldon was a child prodigy with an eidetic memory who began college at the age of eleven and earned a Ph.D. at age sixteen. He is a theoretical physicist researching quantum mechanics and string theory, and, despite his IQ of 187, he finds many routine aspects of social situations difficult to grasp. He is determined to have his own way, continually boasts of his intelligence, and has an extremely ritualized way of living. Despite these quirks, he begins a relationship with Amy Farrah Fowler, and they eventually marry.\n\nKaley Cuoco as Penny: An aspiring actress from Omaha, Nebraska. Penny moves in across the hall from Sheldon and Leonard. She waits tables and occasionally tends the bar at The Cheesecake Factory. After giving up hope of becoming a successful actress, Penny becomes a pharmaceutical sales representative. Penny becomes friends with Bernadette and Amy, and they often hang out in each other's apartments. Penny and Leonard form a relationship and eventually marry.\n\nSimon Helberg as Howard Wolowitz: An aerospace engineer who got his master's degree at the Massachusetts Institute of Technology. Howard is Jewish and lived with his mother, Debbie (Carol Ann Susi). Unlike Sheldon, Leonard, Raj, Bernadette, and Amy, Howard does not hold a doctorate. He trains as an astronaut and goes into space as a payload specialist on the International Space Station. Howard initially fancies himself as a ladies man, but he later starts dating Bernadette, and they get engaged and married. Howard also has a tendency to waste money on toys and argues with Bernadette because of his oddly low income as an engineer and her high income as a pharmaceutical biochemist.\n\nKunal Nayyar as Rajesh Koothrappali: A particle astrophysicist originally from New Delhi, India. Initially, Raj had selective mutism, rendering him unable to talk to or be around women unless under the influence of alcohol. Raj also has very feminine tastes and often takes on a stereotypical female role in his friendship with Howard as well as in the group of four men. Raj later dates Lucy (Kate Micucci), who also suffers from social anxiety, but it eventually ends. He later speaks to Penny without alcohol, overcoming his selective mutism. He begins dating Emily Sweeney, and their relationship later becomes exclusive. In the series' final season, Raj has an on-again, off-again engagement with a fellow Indian, a hotel concierge named Anu (Rati Gupta). He also has a Yorkshire Terrier named Cinnamon.\nThese actors were first credited as guest stars and later promoted to main cast:\n\nSara Gilbert as Leslie Winkle (recurring season 1, starring season 2, guest seasons 3, 9): A physicist who works in the same lab as Leonard. In appearance, she is essentially Leonard's female counterpart and has conflicting scientific theories with Sheldon. Leslie has casual sex with Leonard and later Howard. Gilbert was promoted to a main cast member during the second season but resumed guest star status because producers could not come up with enough material for the character. Gilbert returned to The Big Bang Theory for its 200th episode.\n\nMelissa Rauch as Bernadette Rostenkowski-Wolowitz (recurring season 3, starring seasons 4–12): A young woman who initially is a co-worker at The Cheesecake Factory with Penny to pay her way through graduate school, where she is studying microbiology. Bernadette is introduced to Howard by Penny; at first, they do not get along, apparently having nothing in common. They date and later get engaged and married. Although generally a sweet and good-natured person, Bernadette has a short fuse and can be vindictive and lash out when provoked.\n\nMayim Bialik as Amy Farrah Fowler (guest star season 3, starring seasons 4–12): A woman selected by an online dating site as Sheldon's perfect mate, Amy is from Glendale, CA. While she and Sheldon initially share social cluelessness, after befriending Penny and Bernadette, she eventually becomes more interested in social and romantic interaction. Her relationship with Sheldon slowly progresses to the point at which Sheldon considers her his girlfriend, and eventually, they get married. Amy believes she and Penny are best friends, a sentiment that Penny does not initially share. Amy has a Ph.D. in neurobiology.\n\nKevin Sussman as Stuart Bloom (recurring seasons 2–5, 7, starring seasons 6, 8–12): A mild-mannered, under-confident owner of a comic book store. A competent artist, Stuart is a graduate of the prestigious Rhode Island School of Design. Though he is socially awkward, he possesses slightly better social skills. Stuart implies he is in financial trouble and that the comic book store now also is his home. He is later invited to join the guys' group while Howard is in space. Stuart gets a new job caring for Howard's mother later. After Mrs. Wolowitz's death, Stuart continues to live in her home, along with Howard and Bernadette, until he finds a place of his own.\n\nLaura Spencer as Emily Sweeney (recurring seasons 7–8, 10, starring season 9): A dermatologist at Huntington Hospital. Emily went to Harvard and delights in the macabre, and she states that she likes her job because she can cut things with knives. Prior to meeting Raj, Emily was set up on a blind date with Howard. After finding Emily's online dating profile, Raj has Amy contact her as his wingman instead. Their relationship becomes exclusive, but Raj later breaks up with Emily when he becomes infatuated with Claire (Alessandra Torresani), a bartender and children's author.",

        "evidence": "Bidirectional Encoder Representations from Transformers (BERT) is a novel Transformer BIBREF0 model, which recently achieved state-of-the-art performance in several language understanding tasks, such as question answering, natural language inference, semantic similarity, sentiment analysis, and others BIBREF1. While well-suited to dealing with relatively short sequences, Transformers suffer from a major issue that hinders their applicability in classification of long sequences, i.e. they are able to consume only a limited context of symbols as their input BIBREF2.\nThere are several natural language (NLP) processing tasks that involve such long sequences. Of particular interest are topic identification of spoken conversations BIBREF3, BIBREF4, BIBREF5 and call center customer satisfaction prediction BIBREF6, BIBREF7, BIBREF8, BIBREF9. Call center conversations, while usually quite short and to the point, often involve agents trying to solve very complex issues that the customers experience, resulting in some calls taking even an hour or more. For speech analytics purposes, these calls are typically transcribed using an automatic speech recognition (ASR) system, and processed in textual representations further down the NLP pipeline. These transcripts sometimes exceed the length of 5000 words. Furthermore, temporal information might play an important role in tasks like CSAT. For example, a customer may be angry at the beginning of the call, but after her issue is resolved, she would be very satisfied with the way it was handled. Therefore, simple bag of words models, or any model that does not include temporal dependencies between the inputs, may not be well-suited to handle this category of tasks. This motivates us to employ model such as BERT in this task.\nIn this paper, we propose a method that builds upon BERT's architecture. We split the input text sequence into shorter segments in order to obtain a representation for each of them using BERT. Then, we use either a recurrent LSTM BIBREF10 network, or another Transformer, to perform the actual classification. We call these techniques Recurrence over BERT (RoBERT) and Transformer over BERT (ToBERT). Given that these models introduce a hierarchy of representations (segment-wise and document-wise), we refer to them as Hierarchical Transformers. To the best of our knowledge, no attempt has been done before to use the Transformer architecture for classification of such long sequences.\nOur novel contributions are:\nTwo extensions - RoBERT and ToBERT - to the BERT model, which enable its application in classification of long texts by performing segmentation and using another layer on top of the segment representations.\nState-of-the-art results on the Fisher topic classification task.\nSignificant improvement on the CSAT prediction task over the MS-CNN model.\nTwo extensions - RoBERT and ToBERT - to the BERT model",

        "evidence": "Natural language generation (NLG) has been one of the key topics of research in natural language processing, which was highlighted by the huge body of work on NLG surveyed in BIBREF0, BIBREF1. With the advances of several devices capable of understanding spoken language and conducting conversation with human (e.g., Google Home, Amazon Echo) and the shrinking gap created by the digital devices, it is not difficult to foresee that the market and application areas of NLG systems will continue to grow, especially in applications whose users are non-experts. In such application, a user often asks for certain information and waits for the answer and a NLG module would return the answer in spoken language instead of text such as in question-answering systems or recommendation systems. The NLG system in these two applications uses templates to generate the answers in natural language for the users. A more advanced NLG system in this direction is described in BIBREF2, which works with ontologies annotated using the Attempto language and can generate a natural language description for workflows created by the systems built in the Phylotastic project. The applications targeted by these systems are significantly different from NLG systems, whose main purpose is to generate high-quality natural language description of objects or reports, such as those reported in the recent AAAI conference BIBREF3, BIBREF4, BIBREF5.\nThe present paper is motivated by the need to generate natural language description of computational results to non-expert users such as those developed in the Phylotastic project. In this project, the users are experts in evolutionary biology but are none experts in ontologies and web services. When a user places a request, he/she will receive a workflow consisting of web services, whose inputs and outputs are specified by instances of classes in the ontologies working with web services, as well as the ordering and relationships between the services. To assist the user in understanding the workflow, a natural language description of the workflow is generated. In order to accomplish the task, the NLG system in the Phylotastic project proposes to annotate elements of the ontologies using Attempto, a simple subset of English with precisely defined syntax and semantics.\nIn this paper, we propose a system that addresses the limitation of the system discussed in the Phylotastic project BIBREF2. Specifically, we assume that the annotations given in an ontology are natural language sentences. This is a reasonable assumption given that the developers of an ontology are usually those who have intimate knowledge about entities described in the ontology and often have some sort of comments about classes, objects, and instances of the ontology. We then show that the system is very flexible and can be used for the same purpose with new ontologies.\nThe rest of the paper is organized as follows. Section SECREF2 briefly reviews the basics of Grammatical Framework (GF)BIBREF6. Section SECREF3 describes the main modules of the system. Section SECREF4 includes two use cases of the system using an available ontologies against in the context of reasoning about ontologies. Specifically, it compares with the system used in the Phylotastic project and an ontology about people. This section also contains a use case that highlights the versatility of the proposed system by addressing a challenge to create an abstract Wikipedia BIBREF7. Related works are discussed in Section SECREF5. Section SECREF6 concludes the paper.\nSpecifically, we assume that the annotations given in an ontology are natural language sentences.",

        "evidence": "Language modeling is a probabilistic description of language phenomenon. It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nTo the best of our knowledge this is the first work with the Finnish language to use the following: • Approximation of perplexity using a BERT architecture • Using Transformer-XL architecture with sub-word units. • Comparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.",

        "answer": "An improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data).",
        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data).",

We further study the results with fully random initialization. In the POS tagging experiment, we report the results in Table TABREF48 . While the performance with 4 layers is comparable to the pre-trained Gaussian initialization, deeper projections (8 or 16 layers) result in a dramatic drop in performance. This suggests that the structured syntax model with very deep projections is difficult to train from scratch, and a simpler projection might be a good compromise in the random initialization setting.\nDifferent from the Markov prior in POS tagging experiments, our parsing model seems to be quite sensitive to the initialization. For example, directed accuracy of our approach on sentences of length INLINEFORM0 is below 40.0 with random initialization. This is consistent with previous work that has noted the importance of careful initialization for DMV-based models such as the commonly used harmonic initializer BIBREF2 . However, it is not straightforward to apply the harmonic initializer for DMV directly in our model without using some kind of pre-training since we do not observe gold POS.\nWe investigate the effect of the choice of pre-trained embedding on performance while using our approach.

        "evidence": "To achieve basic objectives and implement fundamental qualities, GAAP has four basic assumptions, four basic principles, and four basic constraints.\n\nAssumptions\nBusiness Entity: assumes that the business is separate from its owners or other businesses. Revenue and expense should be kept separate from personal expenses.\nGoing Concern: assumes that the business will be in operation indefinitely. This validates the methods of asset capitalization, depreciation, and amortization. Only when liquidation is certain this assumption is not applicable. The business will continue to exist in the unforeseeable future.\nMonetary Unit principle: assumes a stable currency is going to be the unit of record. The FASB accepts the nominal value of the US Dollar as the monetary unit of record unadjusted for inflation.\nTime-period principle: implies that the economic activities of an enterprise can be divided into artificial time periods.\nPrinciples\nHistorical cost principle: requires companies to account and report assets and liabilities acquisition costs rather than fair market value. This principle provides information that is reliable (removing opportunity to provide subjective and potentially biased market values), but not very relevant. Thus there is a trend to use fair values. Most debts and securities are now reported at market values.\nRevenue recognition principle: holds that companies should record revenue when earned but not when received. The flow of cash does not have any bearing on the recognition of revenue. This is the essence of accrual basis accounting. Conversely, however, losses must be recognized when their occurrence becomes probable, whether or not it has actually occurred. This comports with the constraint of conservatism, yet brings it into conflict with the constraint of consistency, in that reflecting revenues/gains is inconsistent with the way in which losses are reflected.\nMatching principle: expenses have to be matched with revenues as long as it is reasonable to do so. Expenses are recognized not when the work is performed, or when a product is produced, but when the work or the product actually makes its contribution to revenue. Only if no connection with revenue can be established, cost may be charged as expenses to the current period (e.g., office salaries and other administrative expenses). This principle allows greater evaluation of actual profitability and performance (shows how much was spent to earn revenue). Depreciation and Cost of Goods Sold are good examples of application of this principle.\nFull disclosure principle: Amount and kinds of information disclosed should be decided based on trade-off analysis as a larger amount of information costs more to prepare and use. Information disclosed should be enough to make a judgment while keeping costs reasonable. Information is presented in the main body of financial statements, in the notes or as supplementary information\nConstraints\nObjectivity principle: The company financial statements provided by the accountants should be based on objective evidence.\nMateriality principle: The significance of an item should be considered when it is reported. An item is considered significant when it would affect the decision of a reasonable individual.\nConsistency principle: The company uses the same accounting principles and methods from period to period.\nConservatism principle: When choosing between two solutions, the one which has the less favorable outcome is the solution which should be chosen (see convention of conservatism)\nCost Constraint: The benefits of reporting financial information should justify and be greater than the costs imposed on supplying it.",

Moreover, our model outperforms the model integrated with pretrained word vectors in terms of the overall F1 score on the IWSLT dataset. Based on our contributions, the local representation scheme has the highest impact on the Thai corpus, while the distant representation and CVT result in strong improvements on the English dataset.\nMoreover, our model can also be applied to elementary discourse unit (EDU) segmentation, which is used as the minimal syntactic unit for downstream tasks such as text summarization and machine translation. However, no experiments have been conducted to determine how different sentences and EDUs affect downstream tasks.

        "evidence": "Our motivation for using templates for data synthesis is that seq2seq synthesis models (as discussed in related work) tend to generate irrelevant and repeated words BIBREF17, while templates can produce more coherent and concise output. Also, extracting templates can be done either manually or automatically typically by training a few parameters or even doing no training, then external information in the form of keywords or snippets can be populated into the templates with the help of more sophisticated models. Accordingly, using templates can be very tempting for domains with limited resources such as ours.\nModel Structure. The model consists of 4 modules:\n1. Template extraction: To convert human summaries into templates, we remove keywords in the summary to leave only non-keywords. We use Rapid Automatic Keyword Extraction (RAKE) BIBREF18 to identify keywords.\n2. Template clustering: Upon converting human summaries into templates, we cluster them into $N$ clusters with the goal of using any template from the same cluster interchangeably. A template is first converted into embeddings using a pretrained BERT model BIBREF19, where template embedding is constructed by average pooling word embeddings. Templates are then clustered using k-medoid.\n3. Summary rewriting: An encoder-attention-decoder with pointer network is trained to perform the rewriting task. The model is trained to inject keywords into a template and perform rewriting into a coherent paragraph. The produced rewrites are considered as candidate summaries.\n4. Summary selection: After producing candidate summaries, we need to pick the best ones. We argue that the best candidates are those that are coherent and also convey the same meaning as the original human summary. We thus use a hybrid metric to score candidates, where the metric is a weighted sum of two scores and is calculated using Equations 1, 2, and 3. Eq.1 measures coherency using a language model (LM), Eq.2 measures how close a candidate is to a human summary using ROUGE scores, while Eq.3 picks the highest scored $N$ candidates as the final synthetic set.\nCS and HS are a candidate and human summary. $P(w)$ is the probability of word $w$ using a language model. $\\alpha , \\beta $ are weighting parameters. In this work we use $\\alpha =\\beta =1$ for all experiments. $R_{i}(CS,HS)$ is ROUGE-i score between CS and HS for i=1, 2, and $l$.\nModel Training. Before using the synthesis model, some of the constructing modules (rewriting module, scoring LM) need training. To train the rewriting model, we use another dataset consisting of a set of samples, where each sample can be a text snippet (sentence, paragraph, etc.). For each sample, keywords are extracted using RAKE, then removed. The keywords plus the sample with no keywords are then passed to the rewriting model. The training objective of this model is to reconstruct the original sample, which can be seen as trying to inject extracted keywords back into a template. Model Usage. To use the synthesis model to generate new samples, the set of human summaries are fed to the model, passing through the sub-modules in the following order:\n1. Human summaries first pass through the template extraction module, converting each summary $s_i$ into template $t_i$ and the corresponding keywords $kw_i$.\n2. Templates are then passed to the clustering module, producing a set of clusters. Each cluster $C$ contains a number of similar templates.\n3. For each template $t_i$ and corresponding keywords $kw_i$ from step 1, find the cluster $C_i$ that contains the template $t_i$, then pass the set of templates within that clusters $\\lbrace t_j\\rbrace \\forall {j},$ if $t_j \\in C_i$ alongside the keywords $kw_i$ to the summary rewriting module. This will produce a set of candidate summaries.\n4. The summary selection module scores and selects the highest $N$ candidates as the synthetic summaries.\nOur motivation for using templates for data synthesis is that seq2seq synthesis models (as discussed in related work) tend to generate irrelevant and repeated words (Koehn and Knowles 2017), while templates can produce more coherent and concise output.

The fact that ENL and EFDD are the least cohesive groups in the European Parliament can be attributed to their political focus.

Forward perplexity (PPL-F) indicates the perplexity on the generated data provided by a language model trained on real data to measure the fluency of generated samples. Reverse perplexity (PPL-R) switches the roles of generated data and real data to reflect the discrepancy between the generated distribution and the data distribution. Self-BLEU (S-BLEU) regards each sentence in the generated collection as hypothesis and the others as reference to obtain BLEU scores, which evaluates the diversity of generated results.\nResults are shown in Table TABREF33 . LeakGAN performs best on forward perplexity because it can generate more fluent samples. As for reverse perplexity, our model ARAML beats other baselines, showing that our model can fit the data distribution better. Other GANs, particularly LeakGAN, obtain high reverse perplexity due to mode collapse BIBREF12 , thus they only capture limited fluent expressions, resulting in large discrepancy between the generated distribution and data distribution.

Opinion summarization is the task of automatically generating summaries for a set of opinions about a specific target BIBREF0. Figure FIGREF1 shows various reviews about the movie “Coach Carter” and example summaries generated by humans and automatic systems. The vast majority of previous work BIBREF1 views opinion summarization as the final stage of a three-step process involving: (1) aspect extraction (i.e., finding features pertaining to the target of interest, such as battery life or sound quality); (2) sentiment prediction (i.e., determining the sentiment of the extracted aspects); and (3) summary generation (i.e., presenting the identified opinions to the user). Textual summaries are created following mostly extractive methods which select representative segments (usually sentences) from the source text BIBREF2, BIBREF3, BIBREF4, BIBREF5. Despite being less popular, abstractive approaches seem more appropriate for the task at hand as they attempt to generate summaries which are maximally informative and minimally redundant without simply rearranging passages from the original opinions BIBREF6, BIBREF7, BIBREF8, BIBREF9. General-purpose summarization approaches have recently shown promising results with end-to-end models which are data-driven and take advantage of the success of sequence-to-sequence neural network architectures. Most approaches BIBREF10, BIBREF11, BIBREF12, BIBREF13 encode documents and then decode the learned representations into an abstractive summary, often by attending to the source input BIBREF14 and copying words from it BIBREF15. Under this modeling paradigm, it is no longer necessary to identify aspects and their sentiment for the opinion summarization task, as these are learned indirectly from training data (i.e., sets of opinions and their corresponding summaries). These models are usually tested on domains where the input is either one document or a small set of documents. However, the number of opinions tends to be very large (150 for the example in Figure FIGREF1). It is therefore practically unfeasible to train a model in an end-to-end fashion, given the memory limitations of modern hardware. As a result, current approaches BIBREF16, BIBREF17, BIBREF18, BIBREF19 sacrifice end-to-end elegance in favor of a two-stage framework which we call Extract-Abstract: an extractive model first selects a subset of opinions and an abstractive model then generates the summary while conditioning on the extracted subset (see Figure FIGREF5). The extractive pass unfortunately has two drawbacks. Firstly, on account of having access to a subset of opinions, the summaries can be less informative and inaccurate, as shown in Figure FIGREF1. And secondly, user preferences cannot be easily taken into account (e.g., the reader may wish to obtain a summary focusing on the acting or plot of a movie as opposed to a general-purpose summary) since more specialized information might have been removed.\nIn this paper, we propose Condense-Abstract, an alternative two-stage framework which uses all input documents when generating the summary (see Figure FIGREF5). We view the opinion summarization problem as an instance of multi-source transduction BIBREF20; we first represent the input documents as multiple encodings, aiming to condense their meaning and distill information relating to sentiment and various aspects of the target being reviewed. These condensed representations are then aggregated using a multi-source fusion module based on which an opinion summary is generated using an abstractive model. We also introduce a zero-shot customization technique allowing users to control important aspects of the generated summary at test time. Our approach enables controllable generation while leveraging the full spectrum of opinions available for a specific target. We perform experiments on a dataset consisting of movie reviews and opinion summaries elicited from the Rotten Tomatoes website (BIBREF16; see Figure FIGREF1). Our framework outperforms state-of-the-art models by a large margin using automatic metrics and in a judgment elicitation study. We also verify that our zero-shot customization technique can effectively generate need-specific summaries.\nIn this paper, we propose Condense-Abstract, an alternative two-stage framework which uses all input documents when generating the summary (see Figure FIGREF5).",

Any of the approaches we propose can be used independently of the others. Our approaches without using sentiment labels can be applied to other classification tasks, such as topic classification and concept mining.\nThe experiments show that even unsupervised approaches, as in the corpus-based approach, can outperform supervised approaches in classification tasks. Combining some approaches, which can compensate for what others lack, can help us build better vectors. Our word vectors are created by conventional machine learning algorithms; however, they, as in the corpus-based model, produce state-of-the-art results. Although we preferred to use a classical machine learning algorithm, which is SVM, over a neural network classifier to predict the labels of reviews, we achieved accuracies of over 90 per cent for the Turkish movie corpus and about 88 per cent for the English Twitter dataset.\nWe performed only binary sentiment classification in this study as most of the studies in the literature do.

Exploiting the collaborative structure of Wikipedia, estimators of the level of controversy in a Wikipedia article were developed based on the edit-history of the article BIBREF0, BIBREF3. Along these lines, BIBREF4 detect controversy based on mutual reverts, bi-polarity in the collaboration network, and mutually-reinforced scores for editors and articles. Similarly, BIBREF1 classify whether a Wikipedia page is controversial through the combined evaluation of the topically neighboring set of pages.\nContent analysis of controversial Wikipedia articles has been used to evaluate the level of controversy of other documents (e.g., web pages) by mapping them to related Wikipedia articles BIBREF5. BIBREF6 further build a language model, which enhances predictions made by existing classifiers, by inferring word probabilities from Wikipedia articles prominent in Wikipedia controversy features (mainly signals in edit history as discussed above) and from articles retrieved by manually selected query terms, believed to indicate controversy.\nBIBREF7 detect controversy in news items by inspecting terms with excessive frequency in contexts containing sentiment words, and BIBREF8 study controversy in user comments of news articles using lexicons. Finally, BIBREF9 suggest that controversy is not a universal but rather a community-related concept, and, therefore, should be studied in context.\nHere we measure a concept's controversiality from the explicit sentence-level context in which it is mentioned. In this, our approach is reminiscent of BIBREF10, who suggest a similar approach to detect abstract concepts.\nChoi et al.

        "evidence": "",
        "answer": "Connectomics is the production and study of connectomes: comprehensive maps of connections within an organism's nervous system. More generally, it can be thought of as the study of neuronal wiring diagrams with a focus on how structural connectivity, individual synapses, cellular morphology, and cellular ultrastructure contribute to the make up of a network. The nervous system is a network made of billions of connections and these connections are responsible for our thoughts, emotions, actions, memories, function and dysfunction. Therefore, the study of connectomics aims to advance our understanding of mental health and cognition by understanding how cells in the nervous system are connected and communicate. Because these structures are extremely complex, methods within this field use a high-throughput application of functional and structural neural imaging, most commonly magnetic resonance imaging (MRI), electron microscopy, and histological techniques in order to increase the speed, efficiency, and resolution of these nervous system maps. To date, tens of large scale datasets have been collected spanning the nervous system including the various areas of cortex, cerebellum, the retina, the peripheral nervous system and neuromuscular junctions.\n\nGenerally speaking, there are two types of connectomes; macroscale and microscale. Macroscale connectomics refers to using functional and structural MRI data to map out large fiber tracts and functional gray matter areas within the brain in terms of blood flow (functional) and water diffusivity (structural). Microscale connectomics is the mapping of small organisms' complete connectome using microscopy and histology. That is, all connections that exist in their central nervous system.",

The first few months are a crucial time in shaping your kitten’s emotional and physical well-being. In the first 8 week, there're 4 things you should pay attention to, 1) Always keep kittens warm. Because kittens under four weeks of age do not have the ability to thermoregulate, you must help them maintain body warmth. A warmed Snuggle Safe disk at the opening of the cage or crate is a good idea. 2) Provide kittens with adequate nutrition. Kittens should gain about ½ ounce (14 grams) per day or 4 ounces (113 grams) per week. When feeding,  The temperature of the formula before feeding should be warm to around 100oF or 38oC, but not too hot.3) Keep kittens clean. If kittens are orphaned and do not have a mom to regularly groom then, it is important to teach them to groom and keep them clean. It is okay to wash a kitten with warm water but focus only on the areas needing cleaned.4) Provide socialisation with people and with other kittens. It is good to get them used to contact with people when they're 3 weeks old. They could learn from their littermates and learning from their mom.

The crosslingual latent variables capture correlations between roles in different languages, and regularize the parameter estimates of the monolingual models. Because this is a joint Bayesian model of multilingual SRI, we can apply the same model to a variety of training scenarios just by changing the inference procedure appropriately. We evaluate monolingual SRI with a large unlabeled dataset, bilingual SRI with a parallel corpus, bilingual SRI with annotations available for the source language, and monolingual SRI with a small labeled dataset. Increasing the amount of monolingual unlabeled data significantly improves SRI in German but not in English. Adding word alignments in parallel sentences results in small, non significant improvements, even if there is some labeled data available in the source language. This difficulty in showing the usefulness of parallel corpora for SRI may be due to the current assumptions about role alignments, which mean that only a small percentage of roles are aligned. Further analyses reveals that annotating small amounts of data can easily outperform the performance gains obtained by adding large unlabeled dataset as well as adding parallel corpora.\nFuture work includes training on different language pairs, on more than two languages, and with more inclusive models of role alignment.\nWe propose a Bayesian model of semantic role induction (SRI) that uses crosslingual latent variables to capture role alignments in parallel corpora.",

The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.\n\nA mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds.\n\nIn a typical MS procedure, a sample, which may be solid, liquid, or gaseous, is ionized, for example by bombarding it with a beam of electrons. This may cause some of the sample's molecules to break up into positively charged fragments or simply become positively charged without fragmenting. These ions (fragments) are then separated according to their mass-to-charge ratio, for example by accelerating them and subjecting them to an electric or magnetic field: ions of the same mass-to-charge ratio will undergo the same amount of deflection. The ions are detected by a mechanism capable of detecting charged particles, such as an electron multiplier. Results are displayed as spectra of the signal intensity of detected ions as a function of the mass-to-charge ratio. The atoms or molecules in the sample can be identified by correlating known masses (e.g. an entire molecule) to the identified masses or through a characteristic fragmentation pattern.",

        "evidence": "Story-telling is on the frontier of current text generation technology: stories must remain thematically consistent across the complete document, requiring modeling very long range dependencies; stories require creativity; and stories need a high level plot, necessitating planning ahead rather than word-by-word generation BIBREF0 .\nWe tackle the challenges of story-telling with a hierarchical model, which first generates a sentence called the prompt describing the topic for the story, and then conditions on this prompt when generating the story. Conditioning on the prompt or premise makes it easier to generate consistent stories because they provide grounding for the overall plot. It also reduces the tendency of standard sequence models to drift off topic.\nWe find that standard sequence-to-sequence (seq2seq) models BIBREF1 applied to hierarchical story generation are prone to degenerating into language models that pay little attention to the writing prompt (a problem that has been noted in other domains, such as dialogue response generation BIBREF2 ). This failure is due to the complex and underspecified dependencies between the prompt and the story, which are much harder to model than the closer dependencies required for language modeling (for example, consider the subtle relationship between the first sentence and prompt in Figure FIGREF1 ).\nTo improve the relevance of the generated story to its prompt, we introduce a fusion mechanism BIBREF3 where our model is trained on top of an pre-trained seq2seq model. To improve over the pre-trained model, the second model must focus on the link between the prompt and the story. For the first time, we show that fusion mechanisms can help seq2seq models build dependencies between their input and output.\nAnother major challenge in story generation is the inefficiency of modeling long documents with standard recurrent architectures—stories contain 734 words on average in our dataset. We improve efficiency using a convolutional architecture, allowing whole stories to be encoded in parallel. Existing convolutional architectures only encode a bounded amount of context BIBREF4 , so we introduce a novel gated self-attention mechanism that allows the model to condition on its previous outputs at different time-scales.\nTo train our models, we gathered a large dataset of 303,358 human generated stories paired with writing prompts from an online forum. Evaluating free form text is challenging, so we also introduce new evaluation metrics which isolate different aspects of story generation.\nExperiments show that our fusion and self-attention mechanisms improve over existing techniques on both automated and human evaluation measures. Our new dataset and neural architectures allow for models which can creatively generate longer, more consistent and more fluent passages of text. Human judges prefer our hierarchical model's stories twice as often as those of a non-hierarchical baseline.\nTo train our models, we gathered a large dataset of 303,358 human generated stories paired with writing prompts from an online forum.

To illustrate this, Table TABREF3 presents examples of tweets associated with each of these categories. Five-point scales are widely adopted in review sites like Amazon and TripAdvisor, where a user's sentiment is ordered with respect to its intensity. From a sentiment analysis perspective, this defines a classification problem with five categories. In particular, Sebastiani et al. BIBREF1 defined such classification problems whose categories are explicitly ordered to be ordinal classification problems. To account for the ordering of the categories, learners are penalized according to how far from the true class their predictions are.\nAlthough considering different scales, the various settings of sentiment classification are related. First, one may use the same feature extraction and engineering approaches to represent the text spans such as word membership in lexicons, morpho-syntactic statistics like punctuation or elongated word counts BIBREF2 , BIBREF3 . Second, one would expect that knowledge from one task can be transfered to the others and this would benefit the performance. Knowing that a tweet is “Positive” in the ternary setting narrows the classification decision between the VeryPositive and Positive categories in the fine-grained setting. From a research perspective this raises the question of whether and how one may benefit when tackling such related tasks and how one can transfer knowledge from one task to another during the training phase.\nOur focus in this work is to exploit the relation between the sentiment classification settings and demonstrate the benefits stemming from combining them. To this end, we propose to formulate the different classification problems as a multitask learning problem and jointly learn them. Multitask learning BIBREF4 has shown great potential in various domains and its benefits have been empirically validated BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 using different types of data and learning approaches. An important benefit of multitask learning is that it provides an elegant way to access resources developed for similar tasks. By jointly learning correlated tasks, the amount of usable data increases. For instance, while for ternary classification one can label data using distant supervision with emoticons BIBREF9 , there is no straightforward way to do so for the fine-grained problem. However, the latter can benefit indirectly, if the ternary and fine-grained tasks are learned jointly.\nThe research question that the paper attempts to answer is the following: Can twitter sentiment classification problems, and fine-grained sentiment classification in particular, benefit from multitask learning? To answer the question, the paper brings the following two main contributions: (i) we show how jointly learning the ternary and fine-grained sentiment classification problems in a multitask setting improves the state-of-the-art performance, and (ii) we demonstrate that recurrent neural networks outperform models previously proposed without access to huge corpora while being flexible to incorporate different sources of data.\nOur focus in this work is to exploit the relation between the sentiment classification settings and demonstrate the benefits stemming from combining them.",

        "question": "What is the linguistic difference between open questions and answered questions？",
        "answer": "They are obviously different in word frequency and emotion. and contains content with different levels of attractivity.",
        "evidence": "In this section, we identify various linguistic activities on Quora and propose quantifications of the language usage patterns in this Q&A site. In particular, we show that there exists significant differences in the linguistic structure of the open and the answered questions. Note that most of the measures that we define are simple, intuitive and can be easily obtained automatically from the data (without manual intervention). Therefore the framework is practical, inexpensive and highly scalable.\nContent of a question text is important to attract people and make them engage more toward it. The linguistic structure (i.e., the usage of POS tags, the use of Out-of-Vocabulary words, character usage etc.) one adopts are key factors for answerability of questions. We shall discuss the linguistic structure that often represents the writing style of a question asker.\nIn fig 1 (a), we observe that askers of open questions generally use more no. of words compared to answered questions. To understand the nature of words (standard English words or chat-like words frequently used in social media) used in the text, we compare the words with GNU Aspell dictionary to see whether they are present in the dictionary or not. We observe that both open questions and answered questions follow similar distribution (see fig 1 (b)). Part-of-Speech (POS) tags are indicators of grammatical aspects of texts. To observe how the Part-of-Speech tags are distributed in the question texts, we define a diversity metric. We use the standard CMU POS tagger BIBREF8 for identifying the POS tags of the constituent words in the question. We define the POS tag diversity (POSDiv) of a question $q_i$ as follows: $POSDiv(q_i) = -\\sum _{j \\in pos_{set}}p_j\\times \\log (p_j)$ where $p_j$ is the probability of the $j^{th}$ POS in the set of POS tags. Fig 1 (c) shows that the answered questions have lower POS tag diversity compared to open questions. Question texts undergo several edits so that their readability and the engagement toward them are enhanced. It is interesting to identify how far such edits can make the question different from the original version of it. To capture this phenomena, we have adopted ROUGE-LCS recall BIBREF9 from the domain of text summarization. Higher the recall value, lesser are the changes in the question text. From fig 1 (d), we observe that open questions tend to have higher recall compared to the answered ones which suggests that they have not gone through much of text editing thus allowing for almost no scope of readability enhancement.\nPsycholinguistic analysis: \nThe way an individual talks or writes, give us clue to his/her linguistic, emotional, and cognitive states. A question asker's linguistic, emotional, cognitive states are also revealed through the language he/she uses in the question text. In order to capture such psycholinguistic aspects of the asker, we use Linguistic Inquiry and Word Count (LIWC) BIBREF10 that analyzes various emotional, cognitive, and structural components present in individuals' written texts. LIWC takes a text document as input and outputs a score for the input for each of the LIWC categories such as linguistic (part-of-speech of the words, function words etc.) and psychological categories (social, anger, positive emotion, negative emotion, sadness etc.) based on the writing style and psychometric properties of the document. In table 1 , we perform a comparative analysis of the asker's psycholinguistic state while asking an open question and an answered question.\nAskers of open questions use more function words, impersonal pronouns, articles on an average whereas asker of answered questions use more personal pronouns, conjunctions and adverbs to describe their questions. Essentially, open questions lack content words compared to answered questions which, in turn, affects the readability of the question. As far as the psychological aspects are concerned, answered question askers tend to use more social, family, human related words on average compared to an open question asker. The open question askers express more positive emotions whereas the answered question asker tend to express more negative emotions in their texts. Also, answered question askers are more emotionally involved and their questions reveal higher usage of anger, sadness, anxiety related words compared to that of open questions. Open questions, on the other hand, contains more sexual, body, health related words which might be reasons why they do not attract answers.\nIn table 2 , we show a collection of examples of open questions to illustrate that many of the above quantities based on the linguistic activities described in this section naturally correspond to the factors that human judges consider responsible for a question remaining unanswered. This is one of the prime reasons why these quantities qualify as appropriate indicators of answerability.\nAskers of open questions use more function words, impersonal pronouns, articles on an average whereas asker of answered questions use more personal pronouns, conjunctions and adverbs to describe their questions.Essentially, open questions lack content words compared to answered questions which, in turn, affects the readability of the question.

Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans. The version of LD2NL used in this paper, all experimental results will be publicly available.\nTo validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW.",

        "evidence": "Subword segmentation has become a standard preprocessing step in many neural approaches to natural language processing (NLP) tasks, e.g Neural Machine Translation (NMT) BIBREF0 and Automatic Speech Recognition (ASR) BIBREF1. Word level modeling suffers from sparse statistics, issues with Out-of-Vocabulary (OOV) words, and heavy computational cost due to a large vocabulary. Word level modeling is particularly unsuitable for morphologically rich languages, but subwords are commonly used for other languages as well. Subword segmentation is best suited for languages with agglutinative morphology.\nWhile rule-based morphological segmentation systems can achieve high quality, the large amount of human effort needed makes the approach problematic, particularly for low-resource languages. The systems are language dependent, necessitating use of multiple tools in multilingual setups. As a fast, cheap and effective alternative, data-driven segmentation can be learned in a completely unsupervised manner from raw corpora. Unsupervised morphological segmentation saw much research interest until the early 2010's; for a survey on the methods, see hammarstrom2011unsupervised. Semi-supervised segmentation with already small amounts of annotated training data was found to improve the accuracy significantly when compared to a linguistic segmentation; see ruokolainen2016comparative for a survey. While this line of research has been continued in supervised and more grammatically oriented tasks BIBREF2, the more recent work on unsupervised segmentation is less focused on approximating a linguistically motivated segmentation. Instead, the aim has been to tune subword segmentations for particular applications. For example, the simple substitution dictionary based Byte Pair Encoding segmentation algorithm BIBREF3, first proposed for NMT by sennrich2015neural, has become a standard in the field. Especially in the case of multilingual models, training a single language-independent subword segmentation method is preferable to linguistic segmentation BIBREF4.\nIn this study, we compare three existing and one novel subword segmentation method, all sharing the use of a unigram language model in a generative modeling framework.

        "evidence": "As explained in the introduction, the overarching aim of this project is to investigate in how far information conveyed in social media posts can complement more traditional research methods in clinical psychology to get insights into the recovery experience of individuals with a BD diagnosis. Therefore, we will first conduct a systematic literature review of qualitative evidence to establish a solid base of what is already known about personal recovery experiences in BD for the subsequent social media studies.\nOur research questions, which regard the experiences of different populations, lend themselves to several subprojects. First, we will collect and analyse English-language data from westerners. Then, we will address ethnically diverse English-speaking populations and finally multilingual accounts. This has the advantage that we can build data processing and methodological workflows along an increase in complexity of the data collection and analysis throughout the project.\nIn each project phase, we will employ a mixed-methods approach to combine the advantages of quantitative and qualitative methods BIBREF52 , BIBREF53 , which is established in mental health research BIBREF54 , BIBREF55 , BIBREF56 , BIBREF57 and specifically recommended to investigate personal recovery BIBREF58 . Quantitative methods are suitable to study observable behaviour such as language and yield more generalisable results by taking into account large samples. However, they fall short of capturing the subjective, idiosyncratic meaning of socially constructed reality, which is important when studying individuals' recovery experience BIBREF59 , BIBREF22 , BIBREF23 , BIBREF60 . Therefore, we will apply an explanatory sequential research design BIBREF53 , starting with statistical analysis of the full dataset followed by a manual investigation of fewer examples, similar to `distant reading' BIBREF61 in digital humanities.\nSince previous research mainly employed (semi-)structured interviews and we do not expect to necessarily find the same aspects emphasised in unstructured settings, even less so when looking at a more diverse and non-English speaking population, we will not derive hypotheses from existing recovery models for testing on the online data. Instead, we will start off with exploratory quantitative research using comparative analysis tools such as Wmatrix BIBREF62 to uncover important linguistic features, e.g., on keywords and key concepts that occur with unexpected frequency in our collected datasets relative to reference corpora. The underlying assumption is that keywords and key concepts are indicative of certain aspects of personal recovery, such as those specified in the CHIME model BIBREF24 , other previous research BIBREF22 , BIBREF23 , BIBREF60 , or novel ones. Comparing online sources with transcripts of structured interviews or subcorpora originating from different cultural backgrounds might uncover aspects that were not prominently represented in the accounts studied in prior research.\nA specific challenge will be to narrow down the data to parts relevant for personal recovery, since there is no control over the discussed topics compared to structured interviews. To investigate how individuals discuss personal recovery online and what (potentially unrecorded) aspects they associate with it, without a priori narrowing down the search-space to specific known keywords seems like a chicken-and-egg problem. We propose to address this challenge by an iterative approach similar to the one taken in a corpus linguistic study of cancer metaphors BIBREF63 . Drawing on results from previous qualitative research BIBREF24 , BIBREF23 , we will compile an initial dictionary of recovery-related terms. Next, we will examine a small portion of the dataset manually, which will be partly randomly sampled and partly selected to contain recovery-related terms. Based on this, we will be able to expand the dictionary and additionally automatically annotate semantic concepts of the identified relevant text passages using a semantic tagging approach such as the UCREL Semantic Analysis System (USAS) BIBREF64 . Crucially for the multilingual aspect of the project, USAS can tag semantic categories in eight languages BIBREF8 . Then, semantic tagging will be applied to the full corpus to retrieve all text passages mentioning relevant concepts. Furthermore, distributional semantics methods BIBREF65 , BIBREF66 can be used to find terms that frequently co-occur with words from our keyword dictionary. Occurrences of the identified keywords or concepts can be quantified in the full corpus to identify the importance of the related personal recovery aspects.\nLinguistic Inquiry and Word Count (LIWC) BIBREF67 is a frequently used tool in social-science text analysis to analyse emotional and cognitive components of texts and derive features for classification models BIBREF47 , BIBREF46 , BIBREF68 , BIBREF69 . LIWC counts target words organised in a manually constructed hierarchical dictionary without contextual disambiguation in the texts under analysis and has been psychometrically validated and developed for English exclusively. While translations for several languages exist, e.g., Dutch BIBREF9 , and it is questionable to what extent LIWC concepts can be transferred to other languages and cultures by mere translation. We therefore aim to apply and develop methods that require less manual labour and are applicable to many languages and cultures. One option constitute unsupervised methods, such as topic modelling, which has been applied to explore cultural differences in mental-health related online data already BIBREF37 , BIBREF36 . The Differential Language Analysis ToolKit (DLATK) BIBREF70 facilitates social-scientific language analyses, including tools for preprocessing, such as emoticon-aware tokenisers, filtering according to meta data, and analysis, e.g. via robust topic modelling methods.\nFurthermore, emotion and sentiment analysis constitute useful tools to investigate the emotions involved in talking about recovery and identify factors that facilitate or hinder it. There are many annotated datasets to train supervised classifiers BIBREF71 , BIBREF3 for these actively researched NLP tasks. Machine learning methods were found to usually outperform rule-based approaches based on look-ups in dictionaries such as LIWC. Again, most annotated resources are English, but state of the art approaches based on multilingual embeddings allow transferring models between languages BIBREF4 .\nIn each project phase, we will employ a mixedmethods approach to combine the advantages of quantitative and qualitative methods (Tashakkori and Teddlie, 1998; Creswell and Plano Clark, 2011), which is established in mental health research (Steckler et al., 1992; Baum, 1995; Sale et al., 2002; Lund, 2012) and specifically recommended to investigate personal recovery (Leonhardt et al., 2017).",

        "evidence": "Motivated by the growing interest in matching user account across different social media and networking sites, in this paper we presented models for Digital Stylometry, which is a method for matching users through stylometry inspired techniques. We used temporal and linguistic patterns of users to do the matching.\nWe experimented with linguistic, temporal, and combined temporal-linguistic models using standard and novel techniques. The methods based on our novel confusion model outperformed the more standard ones in all cases. We showed that both temporal and linguistic information are useful for matching users, with the best temporal model performing with an accuracy of $.10$ and the best linguistic model performing with an accuracy of $0.27$ . Even though the linguistic models vastly outperformed the temporal models, when combined the temporal-linguistic models outperformed both with an accuracy of $0.31$ . The improvement in the performance of the combined models suggests that although temporal information is dwarfed by linguistic information, in terms of its contribution to digital stylometry, it nonetheless provides non-overlapping information with the linguistic data.\nOur models were evaluated on $5,612$ users with a total of $11,224$ accounts on Twitter and Facebook combined. In contrast to other works in this area, we did not use any profile information in our matching models. The only information that was used in our models were the time and the linguistic content of posts by the users. This is in accordance with traditional stylometry techniques (since people could lie or misstate this information). Also, we wanted to show that there are implicit clues about the identity of users in the content (language) and context (time) of the users' interactions with social networks that can be used to link their accounts across different services.\nIn addition to the technical contributions (such as our confusion model), we hope that this paper is able to shed light on the relative ease with which seemingly innocuous information can be used to track users across social networks, even when signing up on different services using completely different account and profile information.

Although there can be many possible ways to compute rewards from terminating regions, we will add the results of additional experiments where we replace VIC rewards with a constant 0.01. I.e., we give an agent the constant reward if an option ends. So far, our conclusion is that the constant rewards also produce qualitatively good options, but VIC is better in terms of task adaptation performance.",
        "evidence": "As presented in this section, we conducted two series of experiments to analyze the property of IMTC. First, we qualitatively evaluated the diversity of options learned by IMTC with intrinsic rewards, without any extrinsic rewards. Second, we quantitatively test the reusability of learned options by). Also, we can see that the magnitude of intra-option policies tends larger with constant rewards. Right: Options learned by other methods. OC produces a dead option 3 that terminates everywhere and never-ending options 0 and 1. About intra-option policies, all methods successfully avoided learning the same policy, but they only have two directions.\ntask adaptation on a specific task. As a baseline of termination learning method, we compared our method with OC. OC is trained with VIC rewards during pre-training. We did not compare IMTC with TC because our TC implementation failed to learn options with relatively small termination regions as reported in the paper, and there is no official public code for TC 1 . During pre-training without extrinsic rewards, IMTC receives intrinsic rewards when the current option terminates. We compare three IMTC variants with different intrinsic rewards: (i) VIC, (ii) RVIC, and (iii) constant value (R IMTC = 0.01). Note that R IMTC = 0.01 is chosen from [0.1, 0.05, 0.01] based on the task adaptation results. We also compare IMTC with vanilla VIC and RVIC with fixed termination probabilities. We used ∀ x β o (x) = 0.1 since it performed the best in task adaptation experiments, while 0.05 was used in. Note that RVIC's objective I(X s ; O|x f ) is different from ours, while IMTC and VIC share almost the same objective. Thus, the use of VIC is more natural, and the combination with RVIC is tested to show the applicability of IMTC. Further details of our VIC and RVIC implementation are found in Appendix B. In order to check only the effect of the different methods for learning beta β o , the rest of the implementation is the same for all these methods. That is, OC, vanilla VIC, and vanilla RVIC are also based on PPO and advantage estimation methods in Section 4.2. In this section, we fix the number of options as |O| = 4 for all option-learning methods. We further investigated the effect of the number of options Appendix C, where we confirmed that |O| = 4 is sufficient for most domains. All environments that we used for experiments are implemented on the MuJoCo physics simulator. We further describe the details in Appendix C.\nOption Learning From Intrinsic Rewards We now qualitatively compare the options learned by IMTC with options of other methods. Learned options depend on the reward structure in the environment, which enables manually designing good reward functions for learning diverse options. Thus, we employed a reward-free RL setting where no reward is given to agents. Instead, each compared method uses some intrinsic rewards, as explained. We fix µ as µ(o|x) = 1 |O| in this experiment, since we assume that the future tasks are uniformly distributed. Intra-option policies are trained by PPO and independent GAE (8). We show network architectures and hyperparameters in Appendix C. We set the episode length to 1 × 10 4 , i.e., an agent is reset to its starting position after 1 × 10 4 steps. For all visualizations, we chose the best one from five independent runs with different random seeds.  We visualized learned options in PointReach environment shown in Figure. In this environment, an agent controls the ball initially placed at the center of the room. The state space consists of positions (x, y) and velocities (∆x, ∆y) of an agent, and the action space consists of acceralations ( ∆x ∆t , ∆y ∆t ). Figure shows the options learned in this environment after 4 × 10 6 steps. Each arrow represents the mean value of intra-option policies, and the heatmaps represent β o . In this experiment, we observed the effect of IMTC clearly, for both termination regions and intra-option policies. Interestingly, we don't see clear differences between options learned with VIC and RVIC rewards, while constant rewards tend to make options peaker. OC failed to learn meaningful termination regions: option 0 and 1 never terminate, and option 3 terminates almost everywhere. This result confirms that IMTC can certainly diversify options. Moreover, compared to vanilla VIC and RVIC, intra-option policies learned by IMTC with VIC or RVIC rewards are clearer, in terms of both the magnitude and directions of policies. We believe that this is because diversifying termination regions gives more biased samples to the option classifiers employed by VIC and RVIC. Figure Transferring skills via task adaptation Now we quantitatively test the reusability of learned options by task adaptation with specific reward functions. Specifically, we first trained agents with intrinsic rewards as per the previous section. Then we transferred agents to an environment with the same state and action space but with external rewards. We prepared multiple reward functions, which we call tasks, for each domain and evaluated the averaged performance over tasks. We compare IMTC with OC, vanilla VIC, vanilla RVIC, and PPO without pre-training. Also, we compare three variants of IMTC with different intrinsic rewards during pre-training. For a fair comparison, UGAE (9) and PPO are used for all options learning methods. Note that we found UGAE is very effective in this experiments, as we show the ablation study in Appendix C.6. For vanilla VIC and vanilla RVIC, termination probability is fixed to 0.1 through pre-training and task adaptation. -greedy based on Q O with = 0.1 is used as the option selection policy µ. We hypothesize that diverse options learned by IMTC can help quickly adapt to given tasks, supposing the diversity of tasks.\nFigure shows all domains used for task adaptation experiments. For simplicity, all tasks have goalbased sparse reward functions. I.e., an agent receives R t = 1.0 when it satisfies a goal condition, and otherwise the control cost −0.0001 is given. Red circles show possible goal locations for each task. When the agent fails to reach the goal after 1000 steps, it is reset to a starting position. PointReach, SwimmerReach, and AntReach are simple navigation tasks where an agent aim to just navigate itself to the goal. We also prepared tasks with object manipulation: in PointBilliard and AntBilliard an agent aims to kick the blue ball to the goal position, and in PointPush and AntPush, it has to push the block out of the way to the goal. We pre-traine options learning agents for 4 × 10 6 environmental steps and additionally trained them for 1 × 10 6 steps for each task. Figure shows learning curves and scatter plots drawn from five independent runs with  different random seeds per domain. 2 Here, we observed that IMTC with VIC or RVIC rewards performed the best or was compatible with baselines. IMTC with VIC performed better than OC with VIC except for AntRearch, which backs up the effectiveness of diversifying termination regions for learning reusable options. Also, IMTC with VIC and IMTC with RCIC respectively performed better in most of the tasks than VIC and RVIC with fixed termination probabilities. This result suggests that IMTC can boost the performance of option learning methods based on option classifiers, even when the objective is different as with RVIC. On the other hand, IMTC with constant rewards (R IMTC = 0.01) performed worse than IMTC with VIC or RVIC rewards, although it also learned diverse options as we show in Figure, suggesting the importance of adjusting rewards. We further analyzed the evolution of intrinsic rewards of VIC and RVIC in Appendix C.5. In addition, we can observe that IMTC's performance is especially better than other methods in relatively complex PointBilliard, AntBilliard, and AntPush, where object manipulation is required. Considering that manipulated balls and boxes move faster than agents in these domains, a choice of options can lead to larger differences in the future state. IMTC is suitable to these domains since it maximizes the diversity of the resulting states, while PPO struggles to learn. Contrary, IMTC's performance is close to other methods in Reach tasks, where the goal states are relatively close to the starting states in terms of euclidian distances.\nGridworld experiments and limitation of the method Although IMTC successfully learned diverse options in MuJoCo experiments, our analysis in Figure shows the possibility of learning options that are not interesting but have large MI. We further investigated this possibility by visualizing options in a classical four rooms gridworld in Appendix C.8. Interestingly, we observed that IMTC could fall into diverse but unmeaningful options in that environment. We believe that IMTC is often sufficient in a large environment where a randomly-initialized agent rarely gets the same trajectory. However, when the number of possible trajectories is small, diversifying the destinations could be insufficient. In such cases, it can be necessary to extend IMTC to diversify trajectories as done in.\nIn this experiment, we observed the effect of IMTC clearly, for both termination regions and intra-option policies. Interestingly, we don’t see clear differences between options learned with VIC and RVIC rewards, while constant rewards tend to make options peaker. OC failed to learn meaningful termination regions: option 0 and 1 never terminate, and option 3 terminates almost everywhere. This result confirms that IMTC can certainly diversify options. Moreover, compared to vanilla VIC and RVIC, intra-option policies learned by IMTC with VIC or RVIC rewards are clearer, in terms of both the magnitude and directions of policies.",

It is used to identify and categorise opinions expressed by reviewers on a topic or an entity. Sentiment analysis can be leveraged in marketing, social media analysis, and customer service. Although many studies have been conducted for sentiment analysis in widely spoken languages, this topic is still immature for Turkish and many other languages.\nNeural networks outperform the conventional machine learning algorithms in most classification tasks, including sentiment analysis BIBREF0. In these networks, word embedding vectors are fed as input to overcome the data sparsity problem and make the representations of words more “meaningful” and robust. Those embeddings indicate how close the words are to each other in the vector space model (VSM).\nMost of the studies utilise embeddings, such as word2vec BIBREF1, which take into account the syntactic and semantic representations of the words only. Discarding the sentimental aspects of words may lead to words of different polarities being close to each other in the VSM, if they share similar semantic and syntactic features.\nFor Turkish, there are only a few studies which leverage sentimental information in generating the word and document embeddings. Unlike the studies conducted for English and other widely-spoken languages, in this paper, we use the official dictionaries for this language and combine the unsupervised and supervised scores to generate a unified score for each dimension of the word embeddings in this task.\nOur main contribution is to create original and effective word vectors that capture syntactic, semantic, and sentimental characteristics of words, and use all of this knowledge in generating embeddings. We also utilise the word2vec embeddings trained on a large corpus. Besides using these word embeddings, we also generate hand-crafted features on a review basis and create document vectors. We evaluate those embeddings on two datasets. The results show that we outperform the approaches which do not take into account the sentimental information. We also had better performances than other studies carried out on sentiment analysis in Turkish media. We also evaluated our novel embedding approaches on two English corpora of different genres. We outperformed the baseline approaches for this language as well. The source code and datasets are publicly available.\nThe paper is organised as follows. In Section 2, we present the existing works on sentiment classification. In Section 3, we describe the methods proposed in this work.

        "answer": "They extract the context-independent and context-dependent representations for each entity and relation and combine them to obtain DOLORES embeddings.",
        "evidence": "Having generated a set of paths on knowledge graphs representing local contexts of entities and relations, we are now ready to utilize the machinery of language modeling using deep neural networks to learn Dolores embeddings.\nWhile traditional language models model a sentence as a sequence of words, we adopt the same machinery to model knowledge graph embeddings as follows: (a) A word is an (entity, relation) tuple, (b) we model a sentence as a path consisting of (entity, relation) tuples. Note that we have already established how to generate such paths from the knowledge graph using the path generator component.\nGiven such paths, we would like to model the probability of an entity-relation pair given the history and future context by a Bi-Directional Long Short-Term Memory network. In particular, the forward direction LSTM models: $\n\\text{Pr}([e_1,r_1], [e_2,r_2], \\cdots , [e_N, r_N]) =\n$ \n$$\\prod _{t=1}^{N} \\text{Pr}( [e_t, r_t] \\mid [e_1, r_1], [e_2, r_2], \\cdots , [e_{t-1}, r_{t-1}] ).$$   (Eq. 17) \nSimilarly, the backward direction LSTM models: $\n\\text{Pr}([e_1,r_1], [e_2,r_2], \\cdots , [e_N, r_N]) =\n$ \n$$\\prod _{t=1}^{N} \\text{Pr}( [e_t, r_t] \\mid [e_{t+1}, r_{t+1}], \\cdots , [e_{N}, r_{N}] ).$$   (Eq. 18) \nFigure 2 illustrates this succinctly. At each time-step t, we deal with an entity-relation pair [ $e_t$ , $r_t$ ]. We first map one-hot vectors of the $e_t$ and $r_t$ to an embedding layer, concatenate them to obtain context-independent representations which are then passed through L layers of a Bi-Directional LSTM. Each layer of LSTM outputs the pair's context-dependent representation $\\overrightarrow{h_{t,i}}$ , $\\overleftarrow{h_{t,i}}$ , where i=1, 2, $\\cdots $ , L. Finally, the output of the top layer of LSTM, $\\overrightarrow{h_{t,L}}$ , $\\overleftarrow{h_{t,L}}$ , is used to predict the next pair [ $e_{t+1}$ , $r_t$0 ] and [ $r_t$1 , $r_t$2 ] respectively using a softmax layer. Formally, we jointly maximize the log likelihood of the forward and backward directions: \n$$\\begin{split}\n\\sum _{t=1}^{N}\\log \\text{Pr}([e_t, r_t]\\mid [e_1, r_1],\\cdots ,[e_{t-1}, r_{t-1}];\\mathbf {\\Theta _{F}})+\\\\\n\\sum _{t=1}^{N}\\log \\text{Pr}([e_t, r_t]\\mid [e_{t+1}, r_{t+1}],\\cdots ,[e_{N}, r_{N}];\\mathbf {\\Theta _{B}}),\n\\end{split}$$   (Eq. 19) \nwhere $\\mathbf {\\Theta _{F}}$ = $(\\theta _x, \\overrightarrow{\\theta _{LSTM}}, \\theta _s)$ corresponds to the parameters of the embedding layer, forward-direction LSTM and the softmax layer respectively. Similarly $\\mathbf {\\Theta _{B}}$ = $(\\theta _x, \\overleftarrow{\\theta _{LSTM}}, \\theta _s)$ corresponds to the similar set of parameters for the backward direction. Specifically, note that we share the parameters for the embedding and softmax layer across both directions. We maximize Equation 19 by training the Bi-directional LSTMs using back-propagation through time.\nAfter having estimated the parameters of the Dolores learner, we now extract the context-independent and context-dependent representations for each entity and relation and combine them to obtain Dolores embeddings. More specifically, Dolores embeddings are task specific combination of the context-dependent and context-independent representations learned by our learner. Note that our learner (which is an $L$ -layer Bi-Directional LSTM) computes a set of $2L + 1$ representations for each entity-relation pair which we denote by: $\nR_t = [ x_t, \\overrightarrow{h_{t,i}}, \\overleftarrow{h_{t,i}} \\mid i = 1, 2, \\cdots , \\textit {L} ],\n$ \nwhere $x_t$ is the context-independent embedding and $\\overrightarrow{h_{t,i}}, \\overleftarrow{h_{t,i}}$ correspond to the context-dependent embeddings from layer $i$ .\nGiven a downstream model, Dolores learns a weighted linear combination of the components of $R_t$ to yield a single vector for use in the embedding layer of the downstream model. In particular \n$$\\texttt {\\textsc {Dolores}}_t = [ x_t , \\sum _{i=1}^{L} \\lambda _i h_{t,i} ],$$   (Eq. 23) \nwhere we denote $h_{t,i}$ = [ $\\overrightarrow{h_{t,i}}$ , $\\overleftarrow{h_{t,i}}$ ] and $\\lambda _{i}$ denote task specific learnable weights of the linear combination.\nWhile it is obvious that our embeddings can be used as features for new predictive models, it is also very easy to incorporate our learned Dolores embeddings into existing predictive models on knowledge graphs. The only requirement is that the model accepts as input, an embedding layer (for entities and relations). If a model fulfills this requirement (which a large number of neural models on knowledge graphs do), we can just use Dolores embeddings as a drop-in replacement. We just initialize the corresponding embedding layer with Dolores embeddings. In our evaluation below, we show how to improve several state-of-the-art models on various tasks simply by incorporating Dolores as a drop-in replacement to the original embedding layer.\nAfter having estimated the parameters of the DOLORES learner, we now extract the context-independent and context-dependent representations for each entity and relation and combine them to obtain DOLORES embeddings.",

        "question": "What data is used in Line 2?",
        "answer": "The additional monolingual Europarl.",
        "evidence": "Since the CoNLL annotations have 21 semantic roles in total, we use 21 roles in our model as well as the baseline. Following garg2012unsupervised, we set the number of PRs to 2 (excluding INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ), and SRs to 21-2=19. Table TABREF27 shows the results.\nIn the first setting (Line 1), we train and test the monolingual model on the CoNLL data. We observe significant improvements in F1 score over the Baseline (Line 0) in both languages. Using the CoNLL 2009 dataset alone, titovcrosslingual report an F1 score of 80.9% (PU=86.8%, CO=75.7%) for German. Thus, our monolingual model outperforms their monolingual model in German. For English, they report an F1 score of 83.6% (PU=87.5%, CO=80.1%), but note that our English results are not directly comparable to theirs due to differences argument identification, as discussed in section SECREF25 . As their argument identification score is lower, perhaps their system is discarding “difficult” arguments which leads to a higher clustering score.\nIn the second setting (Line 2), we use the additional monolingual Europarl (EP) data for training. We get equivalent results in English and a significant improvement in German compared to our previous setting (Line 1). The German dataset in CoNLL is quite small and benefits from the additional EP training data. In contrast, the English model is already quite good due to a relatively big dataset from CoNLL, and good accuracy syntactic parsers. Unfortunately, titovcrosslingual do not report results with this setting.\nThe third setting (Line 3) gives the results of our multilingual model, which adds the word alignments in the EP data. Comparing with Line 2, we get non-significant improvements in both languages. titovcrosslingual obtain an F1 score of 82.7% (PU=85.0%, CO=80.6%) for German, and 83.7% (PU=86.8%, CO=80.7%) for English. Thus, for German, our multilingual Bayesian model is able to capture the cross-lingual patterns at least as well as the external penalty term in BIBREF6 . We cannot compare the English results unfortunately due to differences in argument identification.\nWe also compared monolingual and bilingual training data using a setting that emulates the standard supervised setup of separate training and test data sets. We train only on the EP dataset and test on the CoNLL dataset. Lines 4 and 5 of Table TABREF27 give the results. The multilingual model obtains small improvements in both languages, which confirms the results from the standard unsupervised setup, comparing lines 2 to 3.\nThese results indicate that little information can be learned about semantic roles from this parallel data setup. One possible explanation for this result is that the setup itself is inadequate. Given the definition of aligned arguments, only 8% of English arguments and 17% of German arguments are aligned. This plus our experiments suggest that improving the alignment model is a necessary step to making effective use of parallel data in multilingual SRI, for example by joint modeling with SRI. We leave this exploration to future work.\nIn the second setting (Line 2), we use the additional monolingual Europarl (EP) data for training.",

Friends who snowboard may know how to snowboard well, but, they may not be great instructors.  Plus, it's often easy to get frustrated with people you know really well.

        "evidence": "",
        "answer": "The about 14 days trip through the United States starts at Las Vegas. You can easily get a direct flight from Europe to Las Vegas in the States. That makes an easy start for your trip. As you start in Las Vegas take some time to adjust and adapt to the scenery. There are a lot of things to do and see in Las Vegas itself. For example, take a walk along the strip to see all the hotels and casinos, even get inside of one - the Caesars Palace or the Venetian are very interesting. Also there are a lot of show offerings such as Cirque du Soleil or parties in the evening, if you want to have good seats it's best to book your tickets in advance before you start your trip. As you strolled through the city of Las Vegas for two days, on the third day it's time to pick up your rental car. With your rental car begins your road trip through the wide streets of the United states. The first goal for your trip will be Zion Nationalpark in Utah, about a 3 hours drive from Las Vegas. In this national park you have the chance to hike and wander around beautiful nature. One of the most impressive hikes is called Angels Landing. At the highest point of this hike you have a beautiful overview of the whole national park. But be aware that it is necessary to book your ticket for this trail way in advance or if you want to do it on short notice you have to have luck in the lottery. Otherwise you are not allowed to hike this trail. That restriction is necessary because too many people hiked the trail and it became dangerous, so numbers of hikers had to be limited a day. If you spend two day exploring the landscape of Zion Nationalpark it's time to move on to the next location, which is Bryce Canyon National Park also in Utah. It takes around two to 3 hours to drive there from Zion. The area right before the Nationalpark is small with some restaurants, hotels, motels or campgrounds. The Canyon itself is huge and will give you a lot of opportunity to explore. In the wintertime it can be very cold and snowy, therefore bring warm clothes. In the two days you spend there you can visit beautiful overviews on the edge of the canyon and also hike down and explore the deeper canyon. One of the highlights is the amphitheater or Thors' hammer. It is also recommended to watch the sun rise over Bryce Canyon because it's more spectacular from the colors than the sunset in the evening. From Bryce Canyon Nationalpark the road trip continues to the city of Page in Arizona from where you can visit the Antelope Canyon. Take at least one full day there to discover either the upper or the lower Antelope Canyon. But be aware, you have to book tickets in advance! If you don't get a ticket for them there is also Antelope Canyon X, which is a real alternative to visit and maybe even less crowded then the other ones. From this point of the tour you then drive to Grand Canyon National Park, which will take about 3 hours at least. This is probably the highlight of the National Parks in this area of the United States. Recommended is to stay at least for two days, even better if you have more time. You should take one trail down the canyon if you are in the physical state to do this. One most common way down is the south Kalib trail which has a beautiful viewpoint called Ooh Aah Point. If you want to watch the sunset in the evening the desert view watchpoint is a great way to do so. Also take some time to stroll around at Grand Canyon Village, there are some nice souvenir shops and more. From Grand Canyon National Park the road trip then moves on to the last target location, which is Los Angeles in California. It's a longer drive there and takes around 8 hours to drive there. But once you arrive there you will have some nice, relaxing days before your flight back home to Frankfurt. You can spend one day visiting Santa Monica, the beach and the Pier there. It's nice to rent a bicycle out there and ride along the beach side through Venice Beach up to Hermosa beach or even further if you like. Another activity could be to visit Dolby Theatre and the Walk of Fame in Hollywood, there are a lot of shops out there or you can just stroll along. But one thing to be aware of when visiting Los Angeles with a car is that there is always traffic and you can be stuck in traffic many times. As Los Angeles is the last stop on the proposed US-trip on your last day it is time to bring back your rental car right before you fly back, just bring it to the rental car stores at the LAX airport. From this airport you will board your flight back to Europe or somewhere else.",

Recent simulations suggest that a dark matter area, also containing some visible stars, may extend up to a diameter of almost 2 million light-years (613 kpc). The Milky Way has several satellite galaxies and is part of the Local Group of galaxies, which form part of the Virgo Supercluster, which is itself a component of the Laniakea Supercluster.\n\nIt is estimated to contain 100–400 billion stars and at least that number of planets. The Solar System is located at a radius of about 27,000 light-years (8.3 kpc) from the Galactic Center, on the inner edge of the Orion Arm, one of the spiral-shaped concentrations of gas and dust. The stars in the innermost 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The Galactic Center is an intense radio source known as Sagittarius A*, a supermassive black hole of 4.100 (± 0.034) million solar masses. Stars and gases at a wide range of distances from the Galactic Center orbit at approximately 220 kilometers per second. The constant rotational speed appears to contradict the laws of Keplerian dynamics and suggests that much (about 90%) of the mass of the Milky Way is invisible to telescopes, neither emitting nor absorbing electromagnetic radiation.

        "evidence": "As a first corpus, we compiled INLINEFORM0 that represents a collection of 80 excerpts from scientific works including papers, dissertations, book chapters and technical reports, which we have chosen from the well-known Digital Bibliography & Library Project (DBLP) platform. Overall, the documents were written by 40 researchers, where for each author INLINEFORM1 , there are exactly two documents. Given the 80 documents, we constructed for each author INLINEFORM2 two verification problems INLINEFORM3 (a Y-case) and INLINEFORM4 (an N-case). For INLINEFORM5 we set INLINEFORM6 's first document as INLINEFORM7 and the second document as INLINEFORM8 . For INLINEFORM9 we reuse INLINEFORM10 from INLINEFORM11 as the known document and selected a text from another (random) author as the unknown document. The result of this procedure is a set of 80 verification problems, which we split into a training and test set based on a 40/60% ratio. Where possible, we tried to restrict the content of each text to the abstract and conclusion of the original work. However, since in many cases these sections were too short, we also considered other parts of the original works such as introduction or discussion sections. To ensure that the extracted text portions are appropriate for the AV task, each original work was preprocessed manually. More precisely, we removed tables, formulas, citations, quotes and sentences that include non-language content such as mathematical constructs or specific names of researchers, systems or algorithms. The average time span between both documents of an author is 15.6 years. The minimum and maximum time span are 6 and 40 years, respectively. Besides the temporal aspect of INLINEFORM12 , another challenge of this corpus is the formal (scientific) language, where the usage of stylistic devices is more restricted, in contrast to other genres such as novels or poems.\nAs a second corpus, we compiled INLINEFORM0 , which represents a collection of 1,645 chat conversations of 550 sex offenders crawled from the Perverted-Justice portal. The chat conversations stem from a variety of sources including emails and instant messengers (e. g., MSN, AOL or Yahoo), where for each conversation, we ensured that only chat lines from the offender were extracted. We applied the same problem construction procedure as for the corpus INLINEFORM1 , which resulted in 1,100 verification problems that again were split into a training and test set given a 40/60% ratio. In contrast to the corpus INLINEFORM2 , we only performed slight preprocessing. Essentially, we removed user names, time-stamps, URLs, multiple blanks as well as annotations that were not part of the original conversations from all chat lines. Moreover, we did not normalize words (for example, shorten words such as “nooooo” to “no”) as we believe that these represent important style markers. Furthermore, we did not remove newlines between the chat lines, as the positions of specific words might play an important role regarding the individual's writing style.\nAs a third corpus, we compiled INLINEFORM0 , which is a collection of 200 aggregated postings crawled from the Reddit platform. Overall, the postings were written by 100 Reddit users and stem from a variety of subreddits. In order to construct the Y-cases, we selected exactly two postings from disjoint subreddits for each user such that both the known and unknown document INLINEFORM1 and INLINEFORM2 differ in their topic. Regarding the N-cases, we applied the opposite strategy such that INLINEFORM3 and INLINEFORM4 belong to the same topic. The rationale behind this is to figure out to which extent AV methods can be fooled in cases, where the topic matches but not the authorship and vice versa. Since for this specific corpus we have to control the topics of the documents, we did not perform the same procedure applied for INLINEFORM5 and INLINEFORM6 to construct the training and test sets. Instead, we used for the resulting 100 verification problems a 40/60% hold-out split, where both training and test set are entirely disjoint.\nAs a first corpus, we compiled INLINEFORM0 that represents a collection of 80 excerpts from scientific works including papers, dissertations, book chapters and technical reports, which we have chosen from the well-known Digital Bibliography & Library Project (DBLP) platform.\nAs a second corpus, we compiled INLINEFORM0 , which represents a collection of 1,645 chat conversations of 550 sex offenders crawled from the Perverted-Justice portal.\nAs a third corpus, we compiled INLINEFORM0 , which is a collection of 200 aggregated postings crawled from the Reddit platform.",

        "question": "In what manner do they evaluate the model output for sentence completion tasks?",
        "answer": "In a qualitative and a quantitative manner.",
        "evidence": "Recently there has been a considerable interest in language modeling due to various academic and commercial demands. Academically, many studies have investigated this domain such as machine translation, chat-bot, message generation, image tagging and other language-related areas. Commercially, it can be used as a core technology for providing a new application on consumer products or services. For instance, an automatic message-reply prediction service can be launched in mobile devices, thus helping a user to send a reply message when he/she is not provided with a proper input interface.\nTo model the language of human dialogue, a recurrent neural network (RNN) structure is known to show the state of the arts performance with its ability to learn a sequential pattern of the data BIBREF0 . Among the RNN structures, a Long Short-Term Memory RNN (LSTM-RNN) and its variants are successfully used for language modeling tasks BIBREF1 , BIBREF2 . However, as a kind of deep learning technique, the LSTM-RNN and the RNN structure requires both a large number of data and huge computing power to train the model properly. Hence any attempts for applying the RNN structure to personalized language modeling are mainly constrained by the following two limitations. First, personal mobile devices contain private message data among close acquaintances, so users seldom agree to transfer their log out of the devices. This causes a limitation of gathering the whole user data to common computing spaces, where high-performance machines are available. Second, in relatively small computing machines, i.e., smart phone, it is not always-guaranteed to have enough resources to train a deep model within the devices.\nTo resolve these limitations, we propose fast transfer learning schemes. It trains a base model with a large dataset and copies its first n-many layers to the first n-many layers of a target model. Then the target model is fine-tuned with relatively small target data. Several learning schemes such as freezing a certain layer or adding a surplus layer are proposed for achieving the result. In experiments, we trained a general language model with huge corpus such as an Workshop on Statistical Machine Translation (WMT) data and a movie script data by using powerful computing machines, and then transferred the model to target environment for updating to be a personalized language model. With this approach, the final model can mimic target user's language style with proper syntax.\nIn the experiments, we trained the general language model with literary-style data and applied the transfer learning with spoken-style data. Then we evaluated the model output for sentence completion task in a qualitative and a quantitative manner. The test result showed that the model learned the style of the target language properly. Another test was conducted by training the general language model with the script of the drama, “Friends,\" and by applying transfer learning with main character corpora from the script to generate the personalized language model. The message-reply prediction task was evaluated with this model. The test result shows higher similarity between the output of the personalized language model and the same user dialogue than the one between the output of the personalized language model and other users' dialogues.\nThe contributions of this paper are as follows. First, we propose efficient transfer learning schemes for personalized language modeling, which is the first research on transfer learning for RNN based language models with privacy preserving. Second, we show the applicability of our research to the target scenario in the short message reply application by training the model in the similar environment to that of the mobile device, and highlight its test results.\nIn the experiments, we trained the general language model with literary-style data and applied the transfer learning with spoken-style data. Then we evaluated the model output for sentence completion task in a qualitative and a quantitative manner.",

The only modification made to accommodate the fact that we train the model with text in nearly a thousand languages, rather than one, is that language embedding vectors are concatenated to the inputs of the LSTMs at each time step and the hidden layer before the softmax. We used three separate embeddings for these levels, in an attempt to capture different types of information about languages. The model structure is summarized in fig:model.\nIn our experiments we use 1024-dimensional LSTMs, 128-dimensional character embeddings, and 64-dimensional language embeddings. Layer normalization BIBREF5 is used, but no dropout or other regularization since the amount of data is very large (about 3 billion characters) and training examples are seen at most twice.

Heinlein wrote that \"A handy short definition of almost all science fiction might read: realistic speculation about possible future events, based solidly on adequate knowledge of the real world, past and present, and on a thorough understanding of the nature and significance of the scientific method.\"\n\nPart of the reason that it is so difficult to pin down an agreed definition of science fiction is because there is a tendency among science fiction enthusiasts to act as their own arbiter in deciding what exactly constitutes science fiction.

        "question": "Does CAS-LSTMs outperform typical stacked LSTMs?",
        "answer": "Yes",
        "evidence": "In the field of natural language processing (NLP), the most prevalent neural approach to obtaining sentence representations is to use recurrent neural networks (RNNs), where words in a sentence are processed in a sequential and recurrent manner. Along with their intuitive design, RNNs have shown outstanding performance across various NLP tasks e.g. language modeling BIBREF0 , BIBREF1 , machine translation BIBREF2 , BIBREF3 , BIBREF4 , text classification BIBREF5 , BIBREF6 , and parsing BIBREF7 , BIBREF8 .\nAmong several variants of the original RNN BIBREF9 , gated recurrent architectures such as long short-term memory (LSTM) BIBREF10 and gated recurrent unit (GRU) BIBREF2 have been accepted as de-facto standard choices for RNNs due to their capability of addressing the vanishing and exploding gradient problem and considering long-term dependencies. Gated RNNs achieve these properties by introducing additional gating units that learn to control the amount of information to be transferred or forgotten BIBREF11 , and are proven to work well without relying on complex optimization algorithms or careful initialization BIBREF12 .\nMeanwhile, the common practice for further enhancing the expressiveness of RNNs is to stack multiple RNN layers, each of which has distinct parameter sets (stacked RNN) BIBREF13 , BIBREF14 . In stacked RNNs, the hidden states of a layer are fed as input to the subsequent layer, and they are shown to work well due to increased depth BIBREF15 or their ability to capture hierarchical time series BIBREF16 which are inherent to the nature of the problem being modeled.\nHowever this setting of stacking RNNs might hinder the possibility of more sophisticated recurrence-based structures since the information from lower layers is simply treated as input to the next layer, rather than as another class of state that participates in core RNN computations. Especially for gated RNNs such as LSTMs and GRUs, this means that layer-to-layer connections cannot fully benefit from the carefully constructed gating mechanism used in temporal transitions. Some recent work on stacking RNNs suggests alternative methods that encourage direct and effective interaction between RNN layers by adding residual connections BIBREF17 , BIBREF18 , by shortcut connections BIBREF18 , BIBREF19 , or by using cell states of LSTMs BIBREF20 , BIBREF21 .\nIn this paper, we propose a method of constructing multi-layer LSTMs where cell states are used in controlling the vertical information flow. This system utilizes states from the left and the lower context equally in computation of the new state, thus the information from lower layers is elaborately filtered and reflected through a soft gating mechanism. Our method is easy-to-implement, effective, and can replace conventional stacked LSTMs without much modification of the overall architecture.\nWe call the proposed architecture Cell-aware Stacked LSTM, or CAS-LSTM, and evaluate our method on multiple benchmark datasets: SNLI BIBREF22 , MultiNLI BIBREF23 , Quora Question Pairs BIBREF24 , and SST BIBREF25 . From experiments we show that the CAS-LSTMs consistently outperform typical stacked LSTMs, opening the possibility of performance improvement of architectures that use stacked LSTMs.\nOur contribution is summarized as follows.\nThis paper is organized as follows. We give a detailed description about the proposed method in § SECREF2 . Experimental results are given in § SECREF3 . We study prior work related to our objective in § SECREF4 and conclude in § SECREF5 .\nFrom experiments we show that the CAS-LSTMs consistently outperform typical stacked LSTMs, opening the possibility of performance improvement of archi tectures based on stacked LSTMs.",

        "answer": "A financial centre (BE), financial center (AE), or financial hub, is a location with a concentration of participants in banking, asset management, insurance or financial markets with venues and supporting services for these activities to take place. Participants can include financial intermediaries (such as banks and brokers), institutional investors (such as investment managers, pension funds, insurers, and hedge funds), and issuers (such as companies and governments). Trading activity can take place on venues such as exchanges and involve clearing houses, although many transactions take place over-the-counter (OTC), that is directly between participants. Financial centres usually host companies that offer a wide range of financial services, for example relating to mergers and acquisitions, public offerings, or corporate actions; or which participate in other areas of finance, such as private equity, hedge funds, and reinsurance. Ancillary financial services include rating agencies, as well as provision of related professional services, particularly legal advice and accounting services.\n\nThe International Monetary Fund's classes of major financial centres are: International Financial Centres (IFCs), such as New York City, London, and Singapore; Regional Financial Centres (RFCs), such as Shanghai, Shenzhen, Frankfurt, and Sydney; and Offshore Financial Centres (OFCs), such as Cayman Islands, Dublin, and Hong Kong.\n\n\nThe City of London (the \"Square Mile\") is one of the oldest financial centres. London is ranked as one of the largest International Financial Centres in the world.\nInternational Financial Centres, and many Regional Financial Centres, are full–service financial centres with direct access to large capital pools from banks, insurance companies, investment funds, and listed capital markets, and are major global cities. Offshore Financial Centres, and also some Regional Financial Centres, tend to specialise in tax-driven services, such as corporate tax planning tools, tax–neutral vehicles, and shadow banking/securitisation, and can include smaller locations (e.g. Luxembourg), or city-states (e.g. Singapore).

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation.

Injury time goals from Manchester United's Teddy Sheringham and Ole Gunnar Solskjær cancelled out Mario Basler's early goal for Bayern to give Manchester United a 2–1 win. Referee Pierluigi Collina has cited this match as one of the most memorable of his career, and described the noise from the crowd at the end of the game as being like a \"lion's roar\".\n\nThe two sides had played each other earlier in the competition, having both been drawn in Group D in the group stage; Bayern won the group, while Manchester United qualified for the knockout phase as one of the two best runners-up across all six groups. After beating Inter Milan in the quarter-finals, Manchester United beat another Italian side, Juventus, in the semis to reach the final; meanwhile, Bayern beat fellow Germans Kaiserslautern in the quarter-finals, before overcoming Ukrainian side Dynamo Kyiv in the semis.

When Mehmed II ascended the throne again in 1451, he strengthened the Ottoman navy and made preparations to attack Constantinople. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire. After the conquest, Mehmed claimed the title Caesar of the Roman Empire (Ottoman Turkish: قیصر‎ روم, romanized: Qayser-i Rûm), based on the fact that Constantinople had been the seat and capital of the surviving Eastern Roman Empire since its consecration in 330 AD by Emperor Constantine I. The claim was only recognized by the Patriarchate of Constantinople. Nonetheless, Mehmed II viewed the Ottoman state as a continuation of the Roman Empire for the remainder of his life, seeing himself as \"continuing\" the Empire rather than \"replacing\" it.\n\nMehmed continued his conquests in Anatolia with its reunification and in Southeast Europe as far west as Bosnia. At home he made many political and social reforms, encouraged the arts and sciences, and by the end of his reign, his rebuilding program had changed Constantinople into a thriving imperial capital.

        "question": "What do the vector representations of words measure?",
        "answer": "Semantic similarity of vector representations of words.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nThis provides us with vector representations of words, allowing to measure their semantic similarity.",

        "evidence": "Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object.\n\nArchimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle above. Thus, the net force on the object is the difference between the magnitudes of the buoyant force and its weight. If this net force is positive, the object rises; if negative, the object sinks; and if zero, the object is neutrally buoyant—that is, it remains in place without either rising or sinking. In simple words, Archimedes' principle states that, when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body(s).\n\nConsider a cuboid immersed in a fluid, its top and bottom faces orthogonal to the direction of gravity (assumed constant across the cube's stretch). The fluid will exert a normal force on each face, but only the normal forces on top and bottom will contribute to buoyancy. The pressure difference between the bottom and the top face is directly proportional to the height (difference in depth of submersion). Multiplying the pressure difference by the area of a face gives a net force on the cuboid ⁠ ⁠—  the buoyancy ⁠ ⁠—  equaling in size the weight of the fluid displaced by the cuboid. By summing up sufficiently many arbitrarily small cuboids this reasoning may be extended to irregular shapes, and so, whatever the shape of the submerged body, the buoyant force is equal to the weight of the displaced fluid.\n\n weight of displaced fluid = weight of object in vacuum − weight of object in fluid\n\nThe weight of the displaced fluid is directly proportional to the volume of the displaced fluid (if the surrounding fluid is of uniform density). The weight of the object in the fluid is reduced, because of the force acting on it, which is called upthrust. In simple terms, the principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravity.",
        "answer": "When you immerse an object under water, it pushes the water away in order to take its place.\nThe water wants to get back to where it was before and pushes the object away, towards the surface.\nThen it depends what is the weight of the object, compared with how much water was moved.\nImagine you could put your object on one side of a balance, and on the other side, you would duplicate your object and transform it into water (representing how much water is moved if you were to plunge put your object under water).\nIf your original object is lighter than its equivalent in water, like a bubble for example, or a balloon, the water will be strong enough to have the object to float.\nIf the object is heavier than its equivalent water, like a bowling ball, or a rock, the water will not be able to push hard enough, and the object will sink.",

        "answer": "Yes, it does.",
        "evidence": "Paraphrase identification is an important topic in artificial intelligence and this task justifies whether two sentences expressed in various forms are semantically similar, BIBREF0 . For example, “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend” are identified as paraphrase. This task directly benefits many industrial applications, such as plagiarism identification BIBREF0 , machine translation BIBREF1 and removing redundancy questions in Quora website BIBREF2 . Recently, there emerge many methods, such as ABCNN BIBREF3 , Siamese LSTM BIBREF2 and L.D.C BIBREF4 .\nConventionally, neural methodology aligns the sentence pair and then generates a matching score for paraphrase identification, BIBREF4 , BIBREF2 . Regarding the alignment, we conjecture that the aligned unmatched parts are semantically critical, where we define the corresponded word pairs with low similarity as aligned unmatched parts. For an example: “On Sunday, the boy runs in the yard” and “The child runs inside at the weekend”, the matched parts (i.e. (Sunday, weekend), (boy, child), run) barely make contribution to the semantic sentence similarity, but the unmatched parts (i.e. “yard” and “inside”) determine these two sentences are semantically dissimilar. For another example: “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend”, the aligned unmatched parts (i.e. “yard” and “outside”) are semantically similar, which makes the two sentences paraphrase. In conclusion, if the aligned unmatched parts are semantically consistent, the two sentences are paraphrase, otherwise they are non-paraphrase.\nTraditional alignment methods take advantage of attention mechanism BIBREF2 , which is a soft-max weighting technique. Weighting technique could pick out the most similar/dissimilar parts, but is weak in modeling the aligned unmatched parts, which are the crucial evidence to identify paraphrase. For the input sentences in Figure FIGREF1 , the weight between “Sunday” and “run” is lower than the weight between “yard” and “inside”, but the former weight is not the evidence of paraphrase/non-paraphrase, because the former two words that are most dissimilar should not be aligned for an inappropriate comparison.\nTo extract the aligned unmatched parts, in this paper, we embed Hungarian algorithm BIBREF5 into neural architecture as Hungarian layer (Algorithm SECREF7 ). Illustrated in Figure FIGREF1 , the alignment in sentence matching could be formulated as the task-assignment problem, which is tackled by Hungarian algorithm. Simply, Hungarian algorithm works out the theoretically optimal alignment relationship in an exclusive manner and the exclusiveness characterizes the aligned unmatched parts. For the example in Figure FIGREF1 , because Hungarian layer allocates the aligned pairs with exclusiveness, the matched parts (i.e (Sunday, weekend), (boy, child), run) are aligned firstly, then the word “yard” would be assigned to the word “inside” with a negative similarity, making a strong evidence for discrimination.\nSpecifically, our model performs this task in three steps. First, our model applies BiLSTM to parse the input sentences into hidden representations. Then, Hungarian layer leverages the hidden representations to extract the aligned unmatched parts. Last, we apply cosine similarity to metric the aligned unmatched parts for a final discrimination. Regarding the training process of Hungarian layer, we modify the back-propagation algorithm in both directions. In the forward pass, Hungarian layer works out the alignment relationship, according to which, the computational graph is dynamically constructed, as demonstrated in Figure FIGREF13 . Once the computational graph has been dynamically constructed, the backward propagation could be performed as usual in a conventional graph.\nWe conduct our experiments on the public benchmark dataset of “Quora Question Pairs” for the task of paraphrase identification. Experimental results demonstrate that our model outperforms other baselines extensively and significantly, which verifies our theory about the aligned unmatched parts and illustrates the effectiveness of our methodology.\nContributions. (1.) We offer a new perspective for paraphrase identification, which focuses on the aligned unmatched parts of two sentences. Accordingly, we propose the Hungarian layer to extract the aligned unmatched parts. The proposed method can achieve hard and exclusive alignments between two sequences, while we can learn parameters by end-to-end back-propagation. (2.) Our model outperforms other baselines extensively, verifying the effectiveness of our theory and method.\nOrganization. In Section 2, we survey the related work of paraphrase identification and dynamic differentiable computational graphs. In Section 3, we introduce our neural architecture. In Section 4, we conduct the experiments. In Section 5, we conclude our paper and publish our codes.\nExperimental results demonstrate that our model outperforms other baselines extensively and significantly, which verifies our theory about the aligned unmatched parts and illustrates the effectiveness of our methodology.",

        "answer": "They tend to introduce information that cannot be obtained from the image itself, such as people name, location name, time, etc.",
        "evidence": "In this section, we describes procedures of building our sportball Vietnamese dataset, called UIT-ViIC.\nOur human resources for dataset construction involve five writers, whose ages are from 22-25. Being native Vietnamese residents, they are fluent in Vietnamese. All five UIT-ViIC creators first research and are trained about sports knowledge as well as the specialized vocabulary before starting to work.\nDuring annotation process, there are inconsistencies and disagreements between human's understandings and the way they see images. According to Micah Hodosh et al BIBREF5, most images’ captions on Internet nowadays tend to introduce information that cannot be obtained from the image itself, such as people name, location name, time, etc. Therefore, to successfully compose meaningful descriptive captions we expect, their should be strict guidelines.\nInspired from MS-COCO annotation rules BIBREF16, we first sketched UIT-ViIC's guidelines for our captions:\nEach caption must contain at least ten Vietnamese words.\nOnly describe visible activities and objects included in image.\nExclude name of places, streets (Chinatown, New York, etc.) and number (apartment numbers, specific time on TV, etc.)\nFamiliar English words such as laptop, TV, tennis, etc. are allowed.\nEach caption must be a single sentence with continuous tense.\nPersonal opinion and emotion must be excluded while annotating.\nAnnotators can describe the activities and objects from different perspectives.\nVisible “thing” objects are the only one to be described.\nAmbiguous “stuff” objects which do not have obvious “border” are ignored.\nIn case of 10 to 15 objects which are in the same category or species, annotators do not need to include them in the caption.\nIn comparison with MS-COCO BIBREF16 data collection guidelines in terms of annotation, UIT-ViIC’s guidelines has similar rules (1, 2, 8, 9, 10) . We extend from MS-COCO’s guidelines with five new rules to our own and have modifications in the original ones.\nIn both datasets, we would like to control sentence length and focus on describing important subjects only in order to make sure that essential information is mainly included in captions. The MS-COCO threshold for sentence’s length is 8, and we raise the number to 10 for our dataset. One reason for this change is that an object in image is usually expressed in many Vietnamese words. For example, a “baseball player” in English can be translated into “vận động viên bóng chày” or “cầu thủ bóng chày”, which already accounted for a significant length of the Vietnamese sentence. In addition, captions must be single sentences with continuous tense as we expect our model’s output to capture what we are seeing in the image in a consise way.\nOn the other hand, proper name for places, streets, etc must not be mentioned in this dataset in order to avoid confusions and incorrect identification names with the same scenery for output. Besides, annotators’ personal opinion must be excluded for more meaningful captions. Vietnamese words for several English ones such as tennis, pizza, TV, etc are not existed, so annotators could use such familiar words in describing captions. For some images, the subjects are ambiguous and not descriptive which would be difficult for annotators to describe in words. That’s the reason why annotators can describe images from more than one perspective.\nAccording to Micah Hodosh, most images’ captions on Internet nowadays tend to introduce information that cannot be obtained from the image itself, such as people name,location name, time, etc.",

        "evidence": "Human-agent communication at deployment time has been under-explored in machine learning, where the traditional focus has been on building agents that can accomplish tasks on their own (full autonomy). Nevertheless, enabling an agent to exchange information with humans during its operation can potentially enhance its helpfulness and trustworthiness. The ability to request and interpret human advice would help the agent accomplish tasks beyond its built-in knowledge, while the ability to accurately convey when and why it is about to fail would make the agent safer to use.\nIn his classical work, outlines the desired characteristics of cooperative communication, commonly known as the Gricean maxims of cooperation. Among these characteristics are informativeness (the maxim of quantity) and faithfulness (the maxim of quality). Human-agent communication in current work has fallen short in these two aspects. Traditional frameworks like imitation learning and reinforcement learning employ limited communication protocols where the agent and the human can only exchange simple intentions (requesting low-level actions or rewards;). More powerful frameworks like allow the agent to process high-level instructions from humans, but the agent still only requests generic help. Recent work in natural language processing endows the agent with the ability to generate rich natural language utterances, but the communication is not faithful in the sense that the agent only mirrors human-generated utterances without grounding its communication in self-perception of its (in)capabilities and (un)certainties. Essentially it learns to convey what a human may be concerned about, not what it is concerned about. This paper presents a hierarchical reinforcement learning framework named HARI (Human-Assisted Reinforced Interaction), which supports richer and more faithful human-agent communication. Our framework allows the agent to learn to convey intrinstic needs for specific information and to incorporate diverse types of information from humans to make better decisions. Specifically, the agent in HARI is equipped with three information-seeking intentions: in every step, it can choose to request more information about (i) its current state, (ii) the goal state, or (iii) a subgoal state which, if reached, helps it make progress on the current task. Upon receiving a request, the human can transfer new information to the agent by giving new descriptions of the requested state. These de- Initially (A) it may request more information about the goal, but may not know enough about where it currently is. For example, at location B, due to limited perception, it does not recognize that it is in a living room and stands next to a couch. It can obtain such information from the assistant.\nIf the current task becomes too difficult (like at location C), the agent can require the assistant to provide a simpler subtask which, if accomplished, helps it make progress on the main task. The agent maintains a stack of tasks and always executes the task at the top. When the agent receives a (sub)task, it pushes the (sub)task to the top of the stack. When it wants to stop executing a (sub)task, it pops the (sub)task from the stack (e.g., at location D). At location E, the agent empties the stack and terminates its execution.\nscriptions will be incorporated as new inputs to the agent's decision-making policy. The human thus can transfer any form of information that can be interpreted by the policy (e.g., asking the agent to execute skills that it has learned, giving side information that connects the agent to a situation it is more familiar with). Because the agent's policy can implement a variety of model architectures and learning algorithms, our framework opens up many possibilities for human-agent communication.\nTo enable faithful communication, we teach the agent to understand its intrinsic needs by interacting with the human and the environment (rather than imitating human behaviors). By requesting different types of information and observing how much each type of information enhances its decisions, the agent gradually learns to determine which information is most useful to obtain in a given situation. With this capability, at deployment time, it can choose when and what information to ask from the human to improve its task performance. To demonstrate the effectiveness of HARI, we simulate a human-assisted navigation problem where an agent has access to only sparse information about its current state and the goal, and can request additional information about these states. On tasks that take place in previously unseen environments, the ability to ask for help improves the agent's success rate by 7× higher compared to performing tasks only by itself. This human-assisted agent even outperforms an agent that always has access to dense information in unseen environments, thanks to the ability to request subgoals. We show that performance of the agent can be further improved by recursively asking for subgoals of subgoals. We discuss limitations of the policy's model and feature representation, which suggest room for future improvements.\nFigure 1: An illustration of the HARI framework in a human-assisted navigation task. An agent can only observe part of an environment and is asked to find a mug in the kitchen. An assistant communicates with the agent and can provide it with information about the environment and the task. Initially (A) it may request more information about the goal, but may not know enough about where it currently is. For example, at location B, due to limited perception, it does not recognize that it is in a living room and stands next to a couch. It can obtain such information from the assistant.

        "answer": "Firstly, they used CNN for the classification; secondly, they extracted features from the fully-connected layer of the CNN and fed them to an SVM for the final classification.",
        "evidence": "CNN can automatically extract key features from the training data. It grasps contextual local features from a sentence and, after several convolution operations, it forms a global feature vector out of those local features. CNN does not need the hand-crafted features used in traditional supervised classifiers. Such hand-crafted features are difficult to compute and a good guess for encoding the features is always necessary in order to get satisfactory results. CNN, instead, uses a hierarchy of local features which are important to learn context. The hand-crafted features often ignore such a hierarchy of local features.\nFeatures extracted by CNN can therefore be used instead of hand-crafted features, as they carry more useful information. The idea behind convolution is to take the dot product of a vector of INLINEFORM0 weights INLINEFORM1 also known as kernel vector with each INLINEFORM2 -gram in the sentence INLINEFORM3 to obtain another sequence of features INLINEFORM4 . DISPLAYFORM0 \nThus, a max pooling operation is applied over the feature map and the maximum value INLINEFORM0 is taken as the feature corresponding to this particular kernel vector. Similarly, varying kernel vectors and window sizes are used to obtain multiple features BIBREF32 . For each word INLINEFORM1 in the vocabulary, a INLINEFORM2 -dimensional vector representation is given in a look up table that is learned from the data BIBREF33 . The vector representation of a sentence, hence, is a concatenation of vectors for individual words. Similarly, we can have look up tables for other features. One might want to provide features other than words if these features are suspected to be helpful. The convolution kernels are then applied to word vectors instead of individual words.\nWe use these features to train higher layers of the CNN, in order to represent bigger groups of words in sentences. We denote the feature learned at hidden neuron INLINEFORM0 in layer INLINEFORM1 as INLINEFORM2 . Multiple features may be learned in parallel in the same CNN layer. The features learned in each layer are used to train the next layer: DISPLAYFORM0 \nwhere * indicates convolution and INLINEFORM0 is a weight kernel for hidden neuron INLINEFORM1 and INLINEFORM2 is the total number of hidden neurons. The CNN sentence model preserves the order of words by adopting convolution kernels of gradually increasing sizes that span an increasing number of words and ultimately the entire sentence. As mentioned above, each word in a sentence is represented using word embeddings.\nWe employ the publicly available word2vec vectors, which were trained on 100 billion words from Google News. The vectors are of dimensionality 300, trained using the continuous bag-of-words architecture BIBREF33 . Words not present in the set of pre-trained words are initialized randomly. However, while training the neural network, we use non-static representations. These include the word vectors, taken as input, into the list of parameters to be learned during training.\nTwo primary reasons motivated us to use non-static channels as opposed to static ones. Firstly, the common presence of informal language and words in tweets resulted in a relatively high random initialization of word vectors due to the unavailability of these words in the word2vec dictionary. Secondly, sarcastic sentences are known to include polarity shifts in sentimental and emotional degrees. For example, “I love the pain present in breakups\" is a sarcastic sentence with a significant change in sentimental polarity. As word2vec was not trained to incorporate these nuances, we allow our models to update the embeddings during training in order to include them. Each sentence is wrapped to a window of INLINEFORM0 , where INLINEFORM1 is the maximum number of words amongst all sentences in the dataset. We use the output of the fully-connected layer of the network as our feature vector.\nWe have done two kinds of experiments: firstly, we used CNN for the classification; secondly, we extracted features from the fully-connected layer of the CNN and fed them to an SVM for the final classification. The latter CNN-SVM scheme is quite useful for text classification as shown by Poria et al. BIBREF18 . We carry out n-fold cross-validation on the dataset using CNN. In every fold iteration, in order to obtain the training and test features, the output of the fully-connected layer is treated as features to be used for the final classification using SVM. Table TABREF12 shows the training settings for each CNN model developed in this work. ReLU is used as the non-linear activation function of the network. The network configurations of all models developed in this work are given in Table TABREF12 .\nWe have done two kinds of experiments: firstly, we used CNN for the classification; secondly, we extracted features from the fully-connected layer of the CNN and fed them to an SVM for the final classification.",

        "evidence": "China has become the largest producer of raw cashmere, estimated at 19,200 metric tons (in hair) per year (2016). Mongolia follows with 8,900 tons (in hair) as of 2016, while Afghanistan, Iran, Turkey, Kyrgyzstan and other Central Asian republics produce lesser amounts. The annual world raw production is estimated to be between 15,000 and 20,000 tons (13,605 and 18,140 tonnes) (in hair). Pure cashmere, resulting from removing animal grease, dirt and coarse hairs from the fleece, is estimated at 6,500 tons (5,895 tonnes). Ultra-fine Cashmere or Pashmina is still produced by communities in Kashmir but its rarity and high price, along with political instability in the region, make it very hard to source and to regulate quality. It is estimated that the average yearly production per goat is 150 grams (0.33 lb).\n\nPure cashmere can be dyed and spun into yarns and knitted into jumpers (sweaters), hats, gloves, socks and other clothing, or woven into fabrics then cut and assembled into garments such as outer coats, jackets, trousers (pants), pajamas, scarves, blankets, and other items. Fabric and garment producers in Scotland, Italy, and Japan have long been known as market leaders. Cashmere may also be blended with other fibers to bring the garment cost down, or to gain their properties, such as elasticity from wool, or sheen from silk.\n\nThe town of Uxbridge, Massachusetts, in the United States was an incubator for the cashmere wool industry. It had the first power looms for woolens and the first manufacture of \"satinets\". Capron Mill had the first power looms, in 1820.

        "evidence": "To paraphrase the great bard BIBREF21, there is something rotten in the state of the art. We propose Human-And-Model-in-the-Loop Entailment Training (HAMLET), a training procedure to automatically mitigate problems with current dataset collection procedures (see Figure FIGREF1).\nIn our setup, our starting point is a base model, trained on NLI data. Rather than employing automated adversarial methods, here the model's “adversary” is a human annotator. Given a context (also often called a “premise” in NLI), and a desired target label, we ask the human writer to provide a hypothesis that fools the model into misclassifying the label. One can think of the writer as a “white hat” hacker, trying to identify vulnerabilities in the system. For each human-generated example that is misclassified, we also ask the writer to provide a reason why they believe it was misclassified.\nFor examples that the model misclassified, it is necessary to verify that they are actually correct —i.e., that the given context-hypothesis pairs genuinely have their specified target label. The best way to do this is to have them checked by another human. Hence, we provide the example to human verifiers. If two human verifiers agree with the writer, the example is considered a good example. If they disagree, we ask a third human verifier to break the tie. If there is still disagreement between the writer and the verifiers, the example is discarded. Occasionally, verifiers will overrule the original label of the writer.\nOnce data collection for the current round is finished, we construct a new training set from the collected data, with accompanying development and test sets. While the training set includes correctly classified examples, the development and tests sets are built solely from them. The test set was further restricted so as to: 1) include pairs from “exclusive” annotators that are never included in the training data; and 2) be balanced by label classes (and genres, where applicable).

        "question": "Based on the theme of Prometheus movie, who are engineers?",
        "evidence": "The central theme in Prometheus concerns the eponymous Titan of Greek mythology who defies the gods and gifts humanity with fire, for which he is subjected to eternal punishment. The gods want to limit their creations in case they attempt to usurp the gods. The film deals with humanity's relationship with the gods—their creators—and the consequence of defying them. A human expedition intends to find them and receive knowledge about belief, immortality and death. They find superior beings who appear god-like in comparison to humanity, and the Prometheus crew suffer consequences for their pursuit. Shaw is directly responsible for the events of the plot because she wants her religious beliefs affirmed, and believes she is entitled to answers from her god; her questions remain unanswered and she is punished for her hubris. The film offers similar resolution, providing items of information but leaving the connections and conclusions to the audience, potentially leaving the question unanswered. Further religious allusions are implied by the Engineers' decision to punish humanity with destruction 2,000 years before the events of the film. Scott suggested that an Engineer was sent to Earth to stop humanity's increasing aggression, but was crucified, implying it was Jesus Christ. However, Scott felt that an explicit connection in the film would be \"a little too on the nose.\"\n\nArtificial intelligence, a unifying theme throughout Scott's career as a director, is particularly evident in Prometheus, primarily through the android David. David is like humans but does not want to be like them, eschewing a common theme in \"robotic storytelling\" such as in Blade Runner. David is created in the image of humanity, and while the human crew of the Prometheus ship searches for their creators expecting answers, David exists among his human creators yet is unimpressed; he questions his creators about why they are seeking their own. Lindelof described the ship as a prison for David. At the conclusion of the film, David's creator (Weyland) is dead and his fundamental programming will end without someone to serve. Lindelof explained that David's programming becomes unclear and that he could be programmed by Shaw or his own sense of curiosity. Following Weyland's death, David is left with Shaw, and is sincere and interested in following her, partly out of survival and partly out of curiosity.\n\nAnother theme is creation and the question of \"Who Am I? Who Made Me? Why Hast Thou Forsaken Me?\" Development of the in-universe mythology explored the Judeo-Christian creation of humanity, but Scott was interested in Greco-Roman and Aztec creation myths about gods who create humans in their own image by sacrificing a piece of themselves. This creation is shown in the film's opening in which an Engineer sacrifices itself after consuming the dark liquid, acting as a \"gardener in space\" to bring life to a world. One of their expeditions creates humanity, who create artificial life (David) in their own image. David then introduces the dark liquid to Holloway who impregnates a sterile Shaw, and the resulting child impregnates an Engineer, creating the child of all three generations. Scott likened the Engineers to the dark angels of John Milton's Paradise Lost, and said that humanity was their offspring and not God's.\n\nShaw is the only religious believer in the crew and openly displays her religious belief with a necklace of a Christian cross. Lindelof said that with her scientific knowledge, her beliefs felt outdated in 2093. Shaw is excited when she learns that she was created by the Engineers and not a supernatural deity, but rather than cause her to lose her faith, it reinforces it. Lindelof said that asking questions and searching for meaning is the point of being alive, and so the audience is left to question whether Shaw was protected by God because of her faith. Scott wanted the film to end with Shaw's declaration that she is still searching for definitive answers. In addition to the religious themes, Lindelof said that Prometheus is pro-science and explores whether scientific knowledge and faith in God can co-exist.\n\nBeside drawing several influences from Paradise Lost, The Atlantic's Govindini Murty noted further influences, and wrote that \"he striking images Ridley Scott devises for Prometheus reference everything from Stanley Kubrick's 2001 to Leonardo da Vinci's Vitruvian Man and Mario Bava's Planet of the Vampires. Scott also expands on the original Alien universe by creating a distinctly English mythology informed by Milton's Paradise Lost and the symbolic drawings of William Blake.\" In September 2021, a further analysis of the film was reported.",

Parsimonious Attack first proposed discrete optimization which dramatically reduces the search space and save lots of queries, which is essential in black-box attack setting. We also follow this work to use discrete optimization. Square Attack achieves the SOTA success rate (SR) and query efficiency performance in our score-based black-box attack setting. Boundary Attack can constantly reduce the distortion to a very small magnitude. Since our paper focus on imperceptible black-box attack, we also consider this one. For black-box attacks with Bayesian optimization such as (Shukla et al., 2019; Ru et al., 2019), we find they underperform Square Attack in terms of SR and query efficiency, and their distortion are also moderate. Besides, as suggested by Reviewer 2cEz, we tested (Li & Chen, 2021) which also aims to generate imperceptible perturbations.

Qualitative assessment will focus on assessing the functionality of the software, while quantitative more focus on measure the chatbots' performance with a number.\nBased on our investigation of several previous studies, we found that most of the works utilized ISO 9241 to assess chatbots' quality by focusing on the usability aspect. This aspect can be grouped into three focuses, including efficiency, effectiveness, and satisfaction, concerning systems' performance to achieve the specified goals. Here we will explain every focus based on several categories and quality attributes.\nIn automatic evaluation, some studies focus on evaluating the system at emotion level BIBREF15 , BIBREF28 . Therefore, some common metrics such as precision, recall, and accuracy are used to measure system performance, compared to the gold label. This evaluation is similar to emotion classification tasks such as previous SemEval 2018 BIBREF32 and SemEval 2019 . Other studies also proposed to use perplexity to evaluate the model at the content level (to determine whether the content is relevant and grammatical) BIBREF14 , BIBREF39 , BIBREF28 . This evaluation metric is widely used to evaluate dialogue-based systems which rely on probabilistic approach BIBREF61 . Another work by BIBREF14 used BLEU to evaluate the machine response and compare against the gold response (the actual response), although using BLEU to measure conversation generation task is not recommended by BIBREF62 due to its low correlation with human judgment.\nThis evaluation involves human judgement to measure the chatbots' performance, based on several criteria. BIBREF15 used three annotators to rate chatbots' response in two criteria, content (scale 0,1,2) and emotion (scale 0,1). Content is focused on measuring whether the response is natural acceptable and could plausible produced by a human. This metric measurement is already adopted and recommended by researchers and conversation challenging tasks, as proposed in BIBREF38 . Meanwhile, emotion is defined as whether the emotion expression contained in the response agrees with the given gold emotion category. Similarly, BIBREF28 used four annotators to score the response based on consistency, logic and emotion. Consistency measures the fluency and grammatical aspect of the response. Logic measures the degree whether the post and response logically match. Emotion measures the response, whether it contains the appropriate emotion. All of these aspects were measured by three scales 0, 1, and 2. Meanwhile, BIBREF39 proposed naturalness and emotion impact as criteria to evaluate the chatbots' response. Naturalness evaluates whether the response is intelligible, logically follows the context of the conversation, and acceptable as a human response, while emotion impact measures whether the response elicits a positive emotional or triggers an emotionally-positive dialogue, since their study focus only on positive emotion. Another study by BIBREF14 uses crowdsourcing to gather human judgement based on three aspects of performance including empathy/sympathy - did the responses show understanding of the feelings of the person talking about their experience?; relevance - did the responses seem appropriate to the conversation? Were they on-topic?; and fluency - could you understand the responses? Did the language seem accurate?. All of these aspects recorded with three different response, i.e., (1: not at all, 3: somewhat, 5: very much) from around 100 different annotators. After getting all of the human judgement with different criteria, some of these studies used a t-test to get the statistical significance BIBREF28 , BIBREF39 , while some other used inter-annotator agreement measurement such as Fleiss Kappa BIBREF15 , BIBREF14 . Based on these evaluations, they can compare their system performance with baseline or any other state of the art systems.\nWe characterize the evaluation of Emotionally-Aware Chatbot into two different parts, qualitative and quantitative assessment.

        "question": "What do the author do with word subspace in this paper?",
        "answer": "The authors demonstrate the effectiveness of the word subspace formulation and its extension, comparing its performance to various state-of-art methods.",
        "evidence": "Text classification has become an indispensable task due to the rapid growth in the number of texts in digital form available online. It aims to classify different texts, also called documents, into a fixed number of predefined categories, helping to organize data, and making easier for users to find the desired information. Over the past three decades, many methods based on machine learning and statistical models have been applied to perform this task, such as latent semantic analysis (LSA), support vector machines (SVM), and multinomial naive Bayes (MNB).\nThe first step in utilizing such methods to categorize textual data is to convert the texts into a vector representation. One of the most popular text representation models is the bag-of-words model BIBREF0 , which represents each document in a collection as a vector in a vector space. Each dimension of the vectors represents a term (e.g., a word, a sequence of words), and its value encodes a weight, which can be how many times the term occurs in the document.\nDespite showing positive results in tasks such as language modeling and classification BIBREF1 , BIBREF2 , BIBREF3 , the BOW representation has limitations: first, feature vectors are commonly very high-dimensional, resulting in sparse document representations, which are hard to model due to space and time complexity. Second, BOW does not consider the proximity of words and their position in the text and consequently cannot encode the words semantic meanings.\nTo solve these problems, neural networks have been employed to learn vector representations of words BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . In particular, the word2vec representation BIBREF8 has gained attention. Given a training corpus, word2vec can generate a vector for each word in the corpus that encodes its semantic information. These word vectors are distributed in such a way that words from similar contexts are represented by word vectors with high correlation, while words from different contexts are represented by word vectors with low correlation.\nOne crucial aspect of the word2vec representation is that arithmetic and distance calculation between two word vectors can be performed, giving information about their semantic relationship. However, rather than looking at pairs of word vectors, we are interested in studying the relationship between sets of vectors as a whole and, therefore, it is desirable to have a text representation based on a set of these word vectors.\nTo tackle this problem, we introduce the novel concept of word subspace. It is mathematically defined as a low dimensional linear subspace in a word vector space with high dimensionality. Given that words from texts of the same class belong to the same context, it is possible to model word vectors of each class as word subspaces and efficiently compare them in terms of similarity by using canonical angles between the word subspaces. Through this representation, most of the variability of the class is retained. Consequently, a word subspace can effectively and compactly represent the context of the corresponding text. We achieve this framework through the mutual subspace method (MSM) BIBREF9 .\nThe word subspace of each text class is modeled by applying PCA without data centering to the set of word vectors of the class. When modeling the word subspaces, we assume only one occurrence of each word inside the class.\nHowever, as seen in the BOW approach, the frequency of words inside a text is an informative feature that should be considered. In order to introduce this feature in the word subspace modeling and enhance its performance, we further extend the concept of word subspace to the term-frequency (TF) weighted word subspace.\nIn this extension, we consider a set of weights, which encodes the words frequencies, when performing the PCA. Text classification with TF weighted word subspace can also be performed under the framework of MSM. We show the validity of our modeling through experiments on the Reuters database, an established database for natural language processing tasks. We demonstrate the effectiveness of the word subspace formulation and its extension, comparing our methods' performance to various state-of-art methods.\nThe main contributions of our work are:\nThe remainder of this paper is organized as follows. In Section \"Related Work\" , we describe the main works related to text classification. In Section \"Word subspace\" , we present the formulation of our proposed word subspace. In Section \"Conventional text classification methods\" , we explain how text classification with word subspaces is performed under the MSM framework. Then, we present the TF weighted word subspace extension in Section \"TF weighted word subspace\" . Evaluation experiments and their results are described in Section \"Experimental Evaluation\" . Further discussion is then presented in Section \"Discussion\" , and our conclusions are described in Section \"Conclusions and Future Work\" .\nWe demonstrate the effectiveness of the word subspace formulation and its extension, comparing our methods' performance to various state-of-art methods.",

The band's lineup consists of founding members Jeff Ament (bass guitar), Stone Gossard (rhythm guitar), Mike McCready (lead guitar), and Eddie Vedder (lead vocals, guitar), as well as Matt Cameron (drums), who joined in 1998. Keyboardist Boom Gaspar has also been a touring/session member with the band since 2002. Drummers Jack Irons, Dave Krusen, Matt Chamberlain, and Dave Abbruzzese are former members of the band. Pearl Jam outsold many of their contemporaries from the early 1990s, and are considered one of the most influential bands of the decade, being dubbed as \"the most popular American rock and roll band of the '90s\".\n\nFormed after the demise of Gossard and Ament's previous band, Mother Love Bone, Pearl Jam broke into the mainstream with their debut album, Ten, in 1991. Ten stayed on the Billboard 200 chart for nearly five years, and has gone on to become one of the highest-selling rock records ever, going 13× platinum in the United States. Released in 1993, Pearl Jam's second album, Vs., sold over 950,000 copies in its first week of release, setting the record for most copies of an album sold in its first week of release at the time. Their third album, Vitalogy (1994), became the second-fastest-selling CD in history at the time, with more than 877,000 units sold in its first week.\n\nOne of the key bands in the grunge movement of the early 1990s, Pearl Jam's members often shunned popular music industry practices such as making music videos or participating in interviews. The band also sued Ticketmaster, claiming it had monopolized the concert-ticket market. In 2006, Rolling Stone described the band as having \"spent much of the past decade deliberately tearing apart their own fame.\"\n\nPearl Jam had sold more than 85 million albums worldwide by 2018, including nearly 32 million albums in the United States by 2012, making them one of the best-selling bands of all time. Pearl Jam was inducted into the Rock and Roll Hall of Fame in 2017 in its first year of eligibility. They were ranked eighth in a readers' poll by Rolling Stone magazine in its \"Top Ten Live Acts of All Time\" issue. Throughout its career, the band has also promoted wider social and political issues, from pro-abortion rights sentiments to opposition to George W. Bush's presidency. Vedder acts as the band's spokesman on these issues.",

The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.  \n  \nThe aircraft first flew in 1997 and was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Although the USAF had originally planned to buy a total of 750 ATFs, the program was cut to 187 operational aircraft in 2009 due to high costs, a lack of air-to-air missions at the time of production, and the development of the more affordable and versatile F-35.[N 1] The last F-22 was delivered in 2012.  \n  \nWhile it had a protracted development and initial operational difficulties, the F-22 has become a critical component of the USAF's tactical airpower. The fighter's combination of stealth, aerodynamic performance, and mission systems enabled a leap in air combat capabilities and set the benchmark for its generation.

Backups were still seen on the Howard Frankland heading into Tampa, primarily due to a bottleneck at the SR 60/Veterans Expressway exit. On the St. Petersburg side, after a comprehensive reconstruction project that took over ten years, lane counts were increased from four lanes prior to the bridge to six lanes through downtown St. Petersburg, and eight lanes from Gandy Boulevard to the bridge.\n\nA reconstruction project was planned to begin in 2017 for the new Gateway Expressway project, a plan to build a new toll road to connect different parts in Pinellas County. However, FDOT planned to reconstruct the interstate in smaller phases rather than the original larger two-phase project and the start of construction was delayed to 2020.\n\nOnce the reconstruction project is finished in 2025, major traffic congestion on the Howard Frankland bridge is expected to be significantly reduced by the addition of new lanes. On January 7, 2021, FDOT postponed by a week to January 16, 2021 the start date for removing an overpass and the corresponding exit ramp over I-275. It had been scheduled to shut down by 8 p.m., EST, January 9, through January 10. This work was part of the U.S. $600 million toll road project.

Is space-time attention all you need for video understanding?\narXiv preprint arXiv:2102.05095, 2021.",
        "evidence": "In order to capture and filter the relevant information from the comments, we propose a transformerbased Context Adapter Module (CAM) which operates in a residual fashion, additively adapting either the visual or text branch of CLIP with contextual information obtained from the comments (see Fig.). Formally, we are now adding another modality-the comments-to the input which   extends it to x i = (v i , t i , c i,1 , . . . , c i,M ) with c i,k ∈ T . To reduce clutter in the notation, we have defined a fixed number of comments M for each sample. Since both, title and comments, share the same underlying modality, namely text, we can leverage the same encoder to transform comments to embeddings f t (c ik ) = φ c,ik .\nAs we expect the comments to be sometimes unrelated, our Context Adapter Module needs a mechanism to discount off-topic comments and update the primary modality φ v (v i ) or φ t (t i ), steering it in the most informative direction.\nWe introduce this mechanism as a function of both the primary modality and the comment embeddings φ c,ik , as we want to compare the informativeness of all these inputs at a high level. To this end, we design adapter modules g v and g t that extract information from the comments in the form of a residual:\nWith the adapted embeddings φvi and φti we recompute the affinity matrix (now Â) (Eq. 1) and use it for the loss L( Â). This design has several advantages. On one hand, extracting \"only\" a residual from the auxiliary inputs c ik means that the model is easily able to ignore them by predicting g(•) = 0. On the other hand, this effectively allows us to skip the adapter module when we benchmark the model on a dataset that does not have comments, while still learning the joint embedding from richer data.\nIn practice, we implement g as a small transformer architecture. Rather than operating on tokenised words, this transformer operates on embeddings (φ vi and φ ti ) themselves, taking as input the encoded feature from the branch to be adapted, along with comment features φ c,ik . By treating embeddings as tokens in their own right, we allow the embeddings to attend to each other and learn what combinations of the inputs should be used to update the original feature through the residual connection.\nAdditionally, to avoid bleeding information between the two modalities through the Context Adapter Module, during training, we only adapt either the video embedding with g v or the text embedding with g t . If we would use both adapters simultaneously, there is a trivial solution that minimizes the loss L: when the adapters learn to remove the original embedding through the residual, e.g.\nboth adapted embeddings become the same φvi = φti which trivially maximizes their similarity, thus preventing the model to learn a meaningful modality alignment. To prevent the model from learning a transformation of the embedding space through the residual, we train only one adapter at a time. We also consider the case where g v = g t and choose a random modality to adapt for each minibatch, leading to an adapter that is agnostic to the source of the primary embedding.\nWe evaluate our Context Adapter Module on the above described datasets with comments in Table. We find that on both datasets adding comments boosts the retrieval performance significantly, confirming the value of the modality. Further, moving from images to videos also improves the performance. Since KineticsComments (human actions) is quite different to RedditVC (broad range of videos, games, etc.) combining both datasets bridges the domain gap and improves the evaluation performance on KineticsComments.\nBaseline Comparisons. Since the main purpose of the Context Adapter Module is to extract meaningful information from sometimes unrelated auxiliary data, we perform most of the experiments in this section with an image/text backbone using a single video frame instead of a video/text backbone to reduce the computational burden of the evaluation.\nIn Table we evaluate the efficacy of the proposed Context Adapter Module against various baselines in various settings on our RedditVC dataset. The most basic baseline is achieved by not using any form of context adaption, which degenerates the model to the one proposed by.\nAcross all experimental settings, we find that finetuning the backbone architecture helps to improve the performance, while using the proposed CAM with frozen backbones (rows h,k) even outperforms the naive baseline of row (a). We also compare to two baselines. The first baseline is randomly replacing the title features with comments during training (Table(c-d)), however, this does not yield any improvement over no adaptation. In the second baseline we average the title features φ t and the . Surprisingly, we find that training with comments performs best when they are added to the image branch (rows j-l), as opposed to the text-branch (rows g-i). We hypothesize that this is because the comments can better adapt the semantically richer feature of the visual modality as opposed to the text, which can often be as short as a single word.\nAdapting Different Modalities. Since both the visual embedding φ v and the text embedding φ t , come from the same embedding space and should be similar for the same sample, we perform an experiment where we swap the embeddings during evaluation time. In Table we find that there are still differences between φ v and φ t and swapping results in decreased performance. When we train both adapters we can achieve good performance in both cases.  Auxiliary Information. Additionally, Table shows how varying the source of the text at train and test time impacts the retrieval results. Whilst the performance of the model trained with image labels degrades when given comments at evaluation time, a model trained with comments still benefits from image labels at test time. As expected, the performance of both models is negatively impacted when tested with uncorrelated random words as additional text. However, the model trained with image labels does noticeably worse in this setting. This suggests that it has become overly reliant on image labels and easily fooled by irrelevant information, which overrides the title feature.\nVarying the number of comments. In Fig. we vary the number of comments during training and evaluation time. Training on more comments results in better retrieval results when evaluated on the same number of comments. However, while there is little difference for models trained with only a few comments, we found that increasing the number of comments at train time leads to models that are more robust to different number of comments at test time, indicating that training with more comments learns an overall better context adapter module that is then able to work efficiently in various settings.\nFigure 2: Method Overview. We introduce a context adapter module that uses inputs of the auxiliary modality to adapt the embedding of another branch. With this module the model is able to accept or discount information.",

        "answer": "While the TSKM Baseline performs better when considering solely clustering metrics, we argue that the clusters learnt by TSKM are less relevant to our overall prediction task as well as performing worse at identifying separable cluster phenotypes.\nWe clarify the definition of “phenotype” in Section 2 (highlighted in yellow) – a cluster phenotype is a combination of a) trajectory evolution profile, and b) characterisation with regards to an outcome of interest. In our setting, four patient outcomes were considered, based on admission events (or discharge). Outcomes are unknown for new admissions, yet they are ultimately what hospital clinicians are interested in identifying.\nTSKM Clusters are very hard to distinguish with regards to clinical outcome prediction. This can be seen in Table 4, where TSKM performs much worse than CAMELOT (0.55 AUROC for TSKM vs 0.73 AUROC). Furthermore, cluster trajectories learnt by TSKM are less separable with regards to trajectory evolution. We have added to the Appendix Figures A10 and A11 to illustrate this phenomenon, and to justify how pure standard clustering metrics, while useful, might fail to identify relevant feature trends in the input trajectories.",
        "evidence": "EHR data comprise complex time-series data, being high-dimensional, multi-modal and heterogeneous, and thus presenting challenges when used in machine learning models;). An important goal in a medical setting is to identify phenotypically separable clusters with distinct phenotypic profiles (which we denote as phenotypic clustering hereafter). For the purpose of this work, cluster phenotypes result from the combination of two distinct components: a) the evolution profile of patient trajectories' within the cluster, and b) the characterisation of the cluster with regards to clinical variables of interest. The latter may include features not used for clustering and may provide information about the underlying or future health status.\nTraditional clustering models such as K-Means or hierarchical clustering have been shown to fail to capture the existing time-dependent feature relationships. As such, variants have been proposed to mitigate this problem. A temporal version of the K-Means algorithm, Time-Series K-Means (TSKM,), models the distance between time-series of different datapoints, using the Euclidean distance (which is equivalent to considering all temporal observations as an independent feature value for the corresponding patient admission), or time-series alignment strategies such as Dynamic-Time Warping) and soft-DTW, to infer temporal evolution within the latent space. Clustering is performed in the low dimensional latent space through the use of self-organising maps to obtain a discrete, topologically-interpretable latent representation of the learnt clusters. In a supervised setting, AC-TPC serves as the current state-of-the-art for identifying phenotypically separable clusters in patient trajectories in EHR data. AC-TPC maps EHR data into a latent space via an encoder, and uses an actor-critic network which leverages clinical outcomes to aid in cluster formation and obtaining cluster phenotypes. Neither SOM-VAE and AC-TPC provide clinically meaningful interpretation of feature-time importance or outcome of interest.\nAttention mechanisms have recently been proposed to provide greater interpretability to Recurrent Neural Networks (RNN) and to aid in dealing with long-term dependencies, and have also been used in modelling EHR time-series. RETAIN proposes a two-level reverse attention mechanism to mimic physician's decision process and predict a future diagnosis. In other recent works, attention mechanisms based on bi-directional RNN and CNN outperformed standard classification models in predicting high risk vascular diseases with the addition of medication information as input data. A drawback of such attention mechanisms is the focus on temporal interpretability only, and inability to look at individual features, which is key in a medical setting. After processing, input data contained over 100,000 unique patient trajectories corresponding to 4,266 unique patient admissions (only last patients admissions were considered in our analysis).\nOriginal trajectories for the patient cohort are shown in the Appendix in for different variables/features. A lack of clear outcome group separability can be observed across temporal and static variables. Furthermore, we note the high degree of imbalance in the dataadmissions with no event account for over 86.8% of the total number of admissions, while event classes correspond to 10.3% Death, 1.8% ICU and 1.1% Cardiac.\nFor the purpose of this work, cluster phenotypes result from the combination of two distinct components: a) the evolution profile of patient trajectories’ within the cluster, and b) the character_x005f_x0002_isation of the cluster with regards to clinical variables of interest. The latter may include features not used for clustering and may provide information about the underlying or future health status.",

        "question": "What do they combine retrieval and generative dialog systems by?",
        "answer": "By enhancing the generator with the retrieved candidate and  post-reranking of both retrieved and generated candidates.",
        "evidence": "Automatic dialog/conversation systems have served humans for a long time in various fields, ranging from train routing nbcitetrain to museum guiding nbcitemuseum. In the above scenarios, the dialogs are domain-specific, and a typical approach to such in-domain systems is by human engineering, for example, using manually constructed ontologies nbciteyoungsigdial, natural language templates nbcitetemplate, and even predefined dialog states nbcitestatetracking.\nRecently, researchers have paid increasing attention to open-domain, chatbot-style human-computer conversation, because of its important commercial applications, and because it tackles the real challenges of natural language understanding and generation nbciteretrieval1,acl,aaai. For open-domain dialogs, rules and temples would probably fail as we can hardly handle the great diversity of dialog topics and natural language sentences. With the increasing number of human-human conversation utterances available on the Internet, previous studies have developed data-oriented approaches in the open domain, which can be roughly categorized into two groups: retrieval systems and generative systems.\nWhen a user issues an utterance (called a query), retrieval systems search for a most similar query in a massive database (which consists of large numbers of query-reply pairs), and respond to the user with the corresponding reply nbciteretrieval1,retrieval2. Through information retrieval, however, we cannot obtain new utterances, that is, all replies have to appear in the database. Also, the ranking of candidate replies is usually judged by surface forms (e.g., word overlaps, tf $\\cdot $ idf features) and hardly addresses the real semantics of natural languages.\nGenerative dialog systems, on the other hand, can synthesize a new sentence as the reply by language models nbciteBoWdialog,acl,aaai. Typically, a recurrent neural network (RNN) captures the query's semantics with one or a few distributed, real-valued vectors (also known as embeddings); another RNN decodes the query embeddings to a reply. Deep neural networks allow complicated interaction by multiple non-linear transformations; RNNs are further suitable for modeling time-series data (e.g., a sequence of words) especially when enhanced with long short term memory (LSTM) or gated recurrent units (GRUs). Despite these, RNN also has its own weakness when applied to dialog systems: the generated sentence tends to be short, universal, and meaningless, for example, “I don't know” nbcitenaacl or “something” nbciteaaai. This is probably because chatbot-like dialogs are highly diversified and a query may not convey sufficient information for the reply. Even though such universal utterances may be suited in certain dialog context, they make users feel boring and lose interest, and thus are not desirable in real applications.\nIn this paper, we are curious if we can combine the above two streams of approaches for open-domain conversation. To this end, we propose an ensemble of retrieval and generative dialog systems. Given a user-issued query, we first obtain a candidate reply by information retrieval from a large database. The query, along with the candidate reply, is then fed to an utterance generator based on the “bi-sequence to sequence” (biseq2seq) model nbcitemultiseq2seq. Such sequence generator takes into consideration the information contained in not only the query but also the retrieved reply; hence, it alleviates the low-substance problem and can synthesize replies that are more meaningful. After that we use the scorer in the retrieval system again for post-reranking. This step can filter out less relevant retrieved replies or meaningless generated ones. The higher ranked candidate (either retrieved or generated) is returned to the user as the reply.\nFrom the above process, we see that the retrieval and generative systems are integrated by two mechanisms: (1) The retrieved candidate is fed to the sequence generator to mitigate the “low-substance” problem; (2) The post-reranker can make better use of both the retrieved candidate and the generated utterance. In this sense, we call our overall approach an ensemble in this paper. To the best of our knowledge, we are the first to combine retrieval and generative models for open-domain conversation.\nExperimental results show that our ensemble model consistently outperforms each single component in terms of several subjective and objective metrics, and that both retrieval and generative methods contribute an important portion to the overall approach. This also verifies the rationale for building model ensembles for dialog systems.\nFigure 1: The overall architecture of our model ensemble. We combine retrieval and generative dialog systems by 1 enhancing the generator with the retrieved candidate and by 2 post-reranking of both retrieved and generated candidates.",

        "question": "How about the performce of vector space embeddings learned from Flickr tags alone?",
        "answer": "Sometimes outperformed by bag-of-words representations.",
        "evidence": "Users of photo-sharing websites such as Flickr often provide short textual descriptions in the form of tags to help others find the images. With the availability of GPS systems in current electronic devices such as smartphones, latitude and longitude coordinates are nowadays commonly made available as well. The tags associated with such georeferenced photos often describe the location where these photos were taken, and Flickr can thus be regarded as a source of environmental information. The use of Flickr for modelling urban environments has already received considerable attention. For instance, various approaches have been proposed for modelling urban regions BIBREF0 , and for identifying points-of-interest BIBREF1 and itineraries BIBREF2 , BIBREF3 . However, the usefulness of Flickr for characterizing the natural environment, which is the focus of this paper, is less well-understood.\nMany recent studies have highlighted that Flickr tags capture valuable ecological information, which can be used as a complementary source to more traditional sources. To date, however, ecologists have mostly used social media to conduct manual evaluations of image content with little automated exploitation of the associated tags BIBREF4 , BIBREF5 , BIBREF6 . One recent exception is BIBREF7 , where bag-of-words representations derived from Flickr tags were found to give promising result for predicting a range of different environemental phenomena.\nOur main hypothesis in this paper is that by using vector space embeddings instead of bag-of-words representations, the ecological information which is implicitly captured by Flickr tags can be utilized in a more effective way. Vector space embeddings are representations in which the objects from a given domain are encoded using relatively low-dimensional vectors. They have proven useful in natural language processing, especially for encoding word meaning BIBREF8 , BIBREF9 , and in machine learning more generally. In this paper, we are interested in the use of such representations for modelling geographic locations. Our main motivation for using vector space embeddings is that they allow us to integrate the textual information we get from Flickr with available structured information in a very natural way. To this end, we rely on an adaptation of the GloVe word embedding model BIBREF9 , but rather than learning word vectors, we learn vectors representing locations. Similar to how the representation of a word in GloVe is determined by the context words surrounding it, the representation of a location in our model is determined by the tags of the photos that have been taken near that location. To incorporate numerical features from structured environmental datasets (e.g. average temperature), we associate with each such feature a linear mapping that can be used to predict that feature from a given location vector. This is inspired by the fact that salient properties of a given domain can often be modelled as directions in vector space embeddings BIBREF10 , BIBREF11 , BIBREF12 . Finally, evidence from categorical datasets (e.g. land cover types) is taken into account by requiring that locations belonging to the same category are represented using similar vectors, similar to how semantic types are sometimes modelled in the context of knowledge graph embedding BIBREF13 .\nWhile our point-of-departure is a standard word embedding model, we found that the off-the-shelf GloVe model performed surprisingly poorly, meaning that a number of modifications are needed to achieve good results. Our main findings are as follows. First, given that the number of tags associated with a given location can be quite small, it is important to apply some kind of spatial smoothing, i.e. the importance of a given tag for a given location should not only depend on the occurrences of the tag at that location, but also on its occurrences at nearby locations. To this end, we use a formulation which is based on spatially smoothed version of pointwise mutual information. Second, given the wide diversity in the kind of information that is covered by Flickr tags, we find that term selection is in some cases critical to obtain vector spaces that capture the relevant aspects of geographic locations. For instance, many tags on Flickr refer to photography related terms, which we would normally not want to affect the vector representation of a given location. Finally, even with these modifications, vector space embeddings learned from Flickr tags alone are sometimes outperformed by bag-of-words representations. However, our vector space embeddings lead to substantially better predictions in cases where structured (scientific) information is also taken into account. In this sense, the main value of using vector space embeddings in this context is not so much about abstracting away from specific tag usages, but rather about the fact that such representations allow us to integrate numerical and categorical features in a much more natural way than is possible with bag-of-words representations.\nThe remainder of this paper is organized as follows. In the next section, we provide a discussion of existing work. Section SECREF3 then presents our model for embedding geographic locations from Flickr tags and structured data. Next, in Section SECREF4 we provide a detailed discussion about the experimental results. Finally, Section SECREF5 summarizes our conclusions.\nFinally, even with these modifications, vector space embeddings learned from Flickr tags alone are sometimes outperformed by bag-of-words representations.",

        "answer": "Their contributions in this work are three-fold: a novel application of reinforcement learning to sentence ranking for extractive summarization;",
        "evidence": "Automatic summarization has enjoyed wide popularity in natural language processing due to its potential for various information access applications. Examples include tools which aid users navigate and digest web content (e.g., news, social media, product reviews), question answering, and personalized recommendation engines. Single document summarization — the task of producing a shorter version of a document while preserving its information content — is perhaps the most basic of summarization tasks that have been identified over the years (see BIBREF0 , BIBREF0 for a comprehensive overview).\nModern approaches to single document summarization are data-driven, taking advantage of the success of neural network architectures and their ability to learn continuous features without recourse to preprocessing tools or linguistic annotations. Abstractive summarization involves various text rewriting operations (e.g., substitution, deletion, reordering) and has been recently framed as a sequence-to-sequence problem BIBREF1 . Central in most approaches BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 is an encoder-decoder architecture modeled by recurrent neural networks. The encoder reads the source sequence into a list of continuous-space representations from which the decoder generates the target sequence. An attention mechanism BIBREF8 is often used to locate the region of focus during decoding.\nExtractive systems create a summary by identifying (and subsequently concatenating) the most important sentences in a document. A few recent approaches BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 conceptualize extractive summarization as a sequence labeling task in which each label specifies whether each document sentence should be included in the summary. Existing models rely on recurrent neural networks to derive a meaning representation of the document which is then used to label each sentence, taking the previously labeled sentences into account. These models are typically trained using cross-entropy loss in order to maximize the likelihood of the ground-truth labels and do not necessarily learn to rank sentences based on their importance due to the absence of a ranking-based objective. Another discrepancy comes from the mismatch between the learning objective and the evaluation criterion, namely ROUGE BIBREF13 , which takes the entire summary into account.\nIn this paper we argue that cross-entropy training is not optimal for extractive summarization. Models trained this way are prone to generating verbose summaries with unnecessarily long sentences and redundant information. We propose to overcome these difficulties by globally optimizing the ROUGE evaluation metric and learning to rank sentences for summary generation through a reinforcement learning objective. Similar to previous work BIBREF9 , BIBREF11 , BIBREF10 , our neural summarization model consists of a hierarchical document encoder and a hierarchical sentence extractor. During training, it combines the maximum-likelihood cross-entropy loss with rewards from policy gradient reinforcement learning to directly optimize the evaluation metric relevant for the summarization task. We show that this global optimization framework renders extractive models better at discriminating among sentences for the final summary; a sentence is ranked high for selection if it often occurs in high scoring summaries.\nWe report results on the CNN and DailyMail news highlights datasets BIBREF14 which have been recently used as testbeds for the evaluation of neural summarization systems. Experimental results show that when evaluated automatically (in terms of ROUGE), our model outperforms state-of-the-art extractive and abstractive systems. We also conduct two human evaluations in order to assess (a) which type of summary participants prefer (we compare extractive and abstractive systems) and (b) how much key information from the document is preserved in the summary (we ask participants to answer questions pertaining to the content in the document by reading system summaries). Both evaluations overwhelmingly show that human subjects find our summaries more informative and complete.\nOur contributions in this work are three-fold: a novel application of reinforcement learning to sentence ranking for extractive summarization; corroborated by analysis and empirical results showing that cross-entropy training is not well-suited to the summarization task; and large scale user studies following two evaluation paradigms which demonstrate that state-of-the-art abstractive systems lag behind extractive ones when the latter are globally trained.\nThe novel application of reinforcement learning is used to sentence ranking for extractive summarization.",

        "evidence": "Statistic topic models such as Latent Dirichlet Allocation (LDA) and its variants BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 have been proven to be effective in modeling textual documents. In these models, a word token in a document is assumed to be generated by a hidden mixture model, where the hidden variables are the topic indexes for each word and the topic assignments for words are related to document level topic weights. Due to the effectiveness and efficiency in modeling the document generation process, topic models are widely adopted in quite a lot of real world tasks such as sentiment classification BIBREF5 , social network analysis BIBREF6 , BIBREF5 , and recommendation systems BIBREF7 .\nMost topic models take the bag-of-words assumption, in which every document is treated as an unordered set of words and the word tokens in such a document are sampled independently with each other. The bag-of-words assumption brings computational convenience, however, it sacrifices the characterization of sequential properties of words in a document and the topic coherence between words belonging to the same language segment (e.g., sentence). As a result, people have observed many negative examples. Just list one for illustration BIBREF8 : the department chair couches offers and the chair department offers couches have very different topics, although they have exactly the same bag of words.\nThere have been some works trying to solve the aforementioned problems, although still insufficiently. For example, several sentence level topic models BIBREF9 , BIBREF10 , BIBREF11 tackle the topic coherence problem by assuming all the words in a sentence to share the same topic (i.e., every sentence has only one topic). In addition, they model the sequential information by assuming the transition between sentence topics to be Markovian. However, words within the same sentence are still exchangeable in these models, and thus the bag-of-words assumption still holds within a sentence. For another example, in BIBREF12 , the embedding based neural language model BIBREF13 , BIBREF14 , BIBREF15 and topic model are integrated. They assume the generation of a given word in a sentence to depend on its local context (including its preceding words within a fixed window) as well as the topics of the sentence and document it lies in. However, using a fixed window of preceding words, instead of the whole word stream within a sentence, could only introduce limited sequential dependency. Furthermore, there is no explicit coherence constraints on the word topics and sentence topics, since every word can have its own topics in their model.\nWe propose Sentence Level Recurrent Topic Model (SLRTM) to tackle the limitations of the aforementioned works. In the new model, we assume the words in the same sentence to share the same topic in order to guarantee topic coherence, and we assume the generation of a word to rely on the whole history in the same sentence in order to fully characterize the sequential dependency. Specifically, for a particular word INLINEFORM0 within a sentence INLINEFORM1 , we assume its generation depends on two factors: the first is the whole set of its historical words in the sentence and the second is the sentence topic, which we regard as a pseudo word and has its own distributed representations. We use Recurrent Neural Network (RNN) BIBREF16 , such as Long Short Term Memory (LSTM) BIBREF17 or Gated Recurrent Unit (GRU) network BIBREF18 , to model such a long term dependency.\nWith the proposed SLRTM, we can not only model the document generation process more accurately, but also construct new natural sentences that are coherent with a given topic (we call it topic2sentence, similar to image2sentece BIBREF19 ). Topic2sentence has its huge potential for many real world tasks. For example, it can serve as the basis of personalized short text conversation system BIBREF20 , BIBREF21 , in which once we detect that the user is interested in certain topics, we can let these topics speak for themselves using SLRTM to improve the user satisfactory.\nWe have conducted experiments to compare SLRTM with several strong topic model baselines on two tasks: generative model evaluation (i.e. test set perplexity) and document classification. The results on several benchmark datasets quantitatively demonstrate SLRTM's advantages in modeling documents. We further provide some qualitative results on topic2sentence, the generated sentences for different topics clearly demonstrate the power of SLRTM in topic-sensitive short text conversations.\nWe propose Sentence Level Recurrent Topic Model (SLRTM) to tackle the limitations of the aforementioned works. In the new model, we assume the words in the same sentence to share the same topic in order to guarantee topic coherence, and we assume the generation of a word to rely on the whole history in the same sentence in order to fully characterize the sequential dependency.",

We are using the term “tokens” here as a Vietnamese word can consist of one, two or even three tokens. Therefore, to apply Vietnamese properly to Image Captioning, we present a tokenization tool - PyVI BIBREF17, which is specialized for Vietnamese language tokenization, at words level. The sentence length using token-level tokenizer and word-level tokenizer are compared and illustrated in Fig. FIGREF23, we can see there are variances there. So that, we can suggest that the tokenizer performs well enough, and we can expect our Image Captioning models to perform better with Vietnamese sentences that are tokenized, as most models perform more efficiently with captions having fewer words.\nTable TABREF24 summarizes top three most occuring words for each part-of-speech.

        "answer": "It is based on the following observation: the query structure for a complex question may rarely appear, but it usually contains some substructures that frequently appeared in other questions.",
        "evidence": "Knowledge-based question answering (KBQA) aims to answer natural language questions over knowledge bases (KBs) such as DBpedia and Freebase. Formal query generation is an important component in many KBQA systems BIBREF0 , BIBREF1 , BIBREF2 , especially for answering complex questions. Given entity and relation linking results, formal query generation aims to generate correct executable queries, e.g., SPARQL queries, for the input natural language questions. An example question and its formal query are shown in Figure FIGREF1 . Generally speaking, formal query generation is expected to include but not be limited to have the capabilities of (i) recognizing and paraphrasing different kinds of constraints, including triple-level constraints (e.g., “movies\" corresponds to a typing constraint for the target variable) and higher level constraints (e.g., subgraphs). For instance, “the same ... as\" represents a complex structure shown in the middle of Figure FIGREF1 ; (ii) recognizing and paraphrasing aggregations (e.g., “how many\" corresponds to Count); and (iii) organizing all the above to generate an executable query BIBREF3 , BIBREF4 .\nThere are mainly two kinds of query generation approaches for complex questions. (i) Template-based approaches choose a pre-collected template for query generation BIBREF1 , BIBREF5 . Such approaches highly rely on the coverage of templates, and perform unstably when some complex templates have very few natural language questions as training data. (ii) Approaches based on semantic parsing and neural networks learn entire representations for questions with different query structures, by using a neural network following the encode-and-compare framework BIBREF2 , BIBREF4 . They may suffer from the lack of training data, especially for long-tail questions with rarely appeared structures. Furthermore, both above approaches cannot handle questions with unseen query structures, since they cannot generate new query structures.\nTo cope with the above limitations, we propose a new query generation approach based on the following observation: the query structure for a complex question may rarely appear, but it usually contains some substructures that frequently appeared in other questions. For example, the query structure for the question in Figure FIGREF1 appears rarely, however, both “how many movies\" and “the same ... as\" are common expressions, which correspond to the two query substructures in dashed boxes. To collect such frequently appeared substructures, we automatically decompose query structures in the training data. Instead of directly modeling the query structure for the given question as a whole, we employ multiple neural networks to predict query substructures contained in the question, each of which delivers a part of the query intention. Then, we select an existing query structure for the input question by using a combinational ranking function. Also, in some cases, no existing query structure is appropriate for the input question. To cope with this issue, we merge query substructures to build new query structures. The contributions of this paper are summarized below:\nTo cope with the above limitations, we propose a new query generation approach based on the following observation: the query structure for a complex question may rarely appear, but it usually contains some substructures that frequently appeared in other questions.",

        "question": "How much do they achieve improvement on hard similarity small and big datasets through incorporating external commonsense knowledge bringing promising improvements to event embeddings?",
        "answer": "78% and 200%.",
        "evidence": "Events are a kind of important objective information of the world. Structuralizing and representing such information as machine-readable knowledge are crucial to artificial intelligence BIBREF0, BIBREF1. The main idea is to learn distributed representations for structured events (i.e. event embeddings) from text, and use them as the basis to induce textual features for downstream applications, such as script event prediction and stock market prediction.\nParameterized additive models are among the most widely used for learning distributed event representations in prior work BIBREF2, BIBREF3, which passes the concatenation or addition of event arguments' word embeddings to a parameterized function. The function maps the summed vectors into an event embedding space. Furthermore, BIBREF4 ding2015deep and BIBREF5 weber2018event propose using neural tensor networks to perform semantic composition of event arguments, which can better capture the interactions between event arguments.\nThis line of work only captures shallow event semantics, which is not capable of distinguishing events with subtle differences. On the one hand, the obtained event embeddings cannot capture the relationship between events that are syntactically or semantically similar, if they do not share similar word vectors. For example, as shown in Figure FIGREF2 (a), “PersonX threw bomb” and “PersonZ attacked embassy”. On the other hand, two events with similar word embeddings may have similar embeddings despite that they are quite unrelated, for example, as shown in Figure FIGREF2 (b), “PersonX broke record” and “PersonY broke vase”. Note that in this paper, similar events generally refer to events with strong semantic relationships rather than just the same events.\nOne important reason for the problem is the lack of the external commonsense knowledge about the mental state of event participants when learning the objective event representations. In Figure FIGREF2 (a), two event participants “PersonY” and “PersonZ” may carry out a terrorist attack, and hence, they have the same intent: “to bloodshed”, which can help representation learning model maps two events into the neighbor vector space. In Figure FIGREF2 (b), a change to a single argument leads to a large semantic shift in the event representations, as the change of an argument can result in different emotions of event participants. Who “broke the record” is likely to be happy, while, who “broke a vase” may be sad. Hence, intent and sentiment can be used to learn more fine-grained semantic features for event embeddings.\nSuch commonsense knowledge is not explicitly expressed but can be found in a knowledge base such as Event2Mind BIBREF6 and ATOMIC BIBREF7. Thus, we aim to incorporate the external commonsense knowledge, i.e., intent and sentiment, into the learning process to generate better event representations. Specifically, we propose a simple and effective model to jointly embed events, intents and emotions into the same vector space. A neural tensor network is used to learn baseline event embeddings, and we define a corresponding loss function to incorporate intent and sentiment information.\nExtensive experiments show that incorporating external commonsense knowledge brings promising improvements to event embeddings, achieving 78% and 200% improvements on hard similarity small and big dataset, respectively. With better embeddings, we can achieve superior performances on script event prediction and stock market prediction compared to state-of-the-art baseline methods.\nExtensive experiments show that incorporating external commonsense knowledge brings promising improvements to event embeddings, achieving 78% and 200% improvements on hard similarity small and big dataset, respectively.",

The PA process enables an organization to periodically measure and evaluate every employee's performance. It also provides a mechanism to link the goals established by the organization to its each employee's day-to-day activities and performance. Design and analysis of PA processes is a lively area of research within the HR community BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 .\nThe PA process in any modern organization is nowadays implemented and tracked through an IT system (the PA system) that records the interactions that happen in various steps. Availability of this data in a computer-readable database opens up opportunities to analyze it using automated statistical, data-mining and text-mining techniques, to generate novel and actionable insights / patterns and to help in improving the quality and effectiveness of the PA process BIBREF4 , BIBREF5 , BIBREF6 . Automated analysis of large-scale PA data is now facilitated by technological and algorithmic advances, and is becoming essential for large organizations containing thousands of geographically distributed employees handling a wide variety of roles and tasks.\nA typical PA process involves purposeful multi-step multi-modal communication between employees, their supervisors and their peers. In most PA processes, the communication includes the following steps: (i) in self-appraisal, an employee records his/her achievements, activities, tasks handled etc.; (ii) in supervisor assessment, the supervisor provides the criticism, evaluation and suggestions for improvement of performance etc.; and (iii) in peer feedback (aka INLINEFORM0 view), the peers of the employee provide their feedback. There are several business questions that managers are interested in. Examples:\nIn this paper, we develop text mining techniques that can automatically produce answers to these questions. Since the intended users are HR executives, ideally, the techniques should work with minimum training data and experimentation with parameter setting. These techniques have been implemented and are being used in a PA system in a large multi-national IT company.\nThe rest of the paper is organized as follows. Section SECREF2 summarizes related work. Section SECREF3 summarizes the PA dataset used in this paper. Section SECREF4 applies sentence classification algorithms to automatically discover three important classes of sentences in the PA corpus viz., sentences that discuss strengths, weaknesses of employees and contain suggestions for improving her performance. Section SECREF5 considers the problem of mapping the actual targets mentioned in strengths, weaknesses and suggestions to a fixed set of attributes. In Section SECREF6 , we discuss how the feedback from peers for a particular employee can be summarized.

        "answer": "Yes.",
        "evidence": "The new generation of Neural Machine Translation (NMT) systems is known to be extremely data hungry BIBREF0 . Yet, most existing NMT training pipelines fail to fully take advantage of the very large volume of monolingual source and/or parallel data that is often available. Making a better use of data is particularly critical in domain adaptation scenarios, where parallel adaptation data is usually assumed to be small in comparison to out-of-domain parallel data, or to in-domain monolingual texts. This situation sharply contrasts with the previous generation of statistical MT engines BIBREF1 , which could seamlessly integrate very large amounts of non-parallel documents, usually with a large positive effect on translation quality.\nSuch observations have been made repeatedly and have led to many innovative techniques to integrate monolingual data in NMT, that we review shortly. The most successful approach to date is the proposal of BIBREF2 , who use monolingual target texts to generate artificial parallel data via backward translation (BT). This technique has since proven effective in many subsequent studies. It is however very computationally costly, typically requiring to translate large sets of data. Determining the “right” amount (and quality) of BT data is another open issue, but we observe that experiments reported in the literature only use a subset of the available monolingual resources. This suggests that standard recipes for BT might be sub-optimal.\nThis paper aims to better understand the strengths and weaknesses of BT and to design more principled techniques to improve its effects. More specifically, we seek to answer the following questions: since there are many ways to generate pseudo parallel corpora, how important is the quality of this data for MT performance? Which properties of back-translated sentences actually matter for MT quality? Does BT act as some kind of regularizer BIBREF3 ? Can BT be efficiently simulated? Does BT data play the same role as a target-side language modeling, or are they complementary? BT is often used for domain adaptation: can the effect of having more in-domain data be sorted out from the mere increase of training material BIBREF2 ? For studies related to the impact of varying the size of BT data, we refer the readers to the recent work of BIBREF4 .\nTo answer these questions, we have reimplemented several strategies to use monolingual data in NMT and have run experiments on two language pairs in a very controlled setting (see § SECREF2 ). Our main results (see § SECREF4 and § SECREF5 ) suggest promising directions for efficient domain adaptation with cheaper techniques than conventional BT.\nTo our knowledge, this is the first work systematically exploring the cross-lingual transferring ability of multi-BERT on RC tasks.",

        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier. When we combine the two models, we achieve state-of-the-art results over 3/4 of our datasets.\nThis paper makes the following contributions:\nAll code and data associated with this research will be released on publication.\nWe perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by Kang et al.

        "answer": "The Wimbledon Championships, commonly known simply as Wimbledon, is the oldest tennis tournament in the world and is widely regarded as the most prestigious. It has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts, with retractable roofs over the two main courts since 2019.\n\nWimbledon is one of the four Grand Slam tennis tournaments, the others being the Australian Open, the French Open, and the US Open. Wimbledon is the only major still played on grass, the traditional tennis playing surface. Also, it is the only Grand Slam that retains a night-time curfew, though matches can now continue until 11.00 pm under the lights.\n\nThe tournament traditionally takes place over two weeks in late June and early July, starting on the last Monday in June and culminating with the Ladies' and Gentlemen's Singles Finals, scheduled for the Saturday and Sunday at the end of the second week. Five major events are held each year, with additional junior and invitational competitions also taking place. In 2009, Wimbledon's Centre Court was fitted with a retractable roof to lessen the loss of playing time due to rain. A roof was operational over No. 1 Court from 2019, when a number of other improvements were made, including adding cushioned seating, a table and 10 independently operable cameras per court to capture the games.\n\nWimbledon traditions include a strict all-white dress code for competitors, and royal patronage. Strawberries and cream are traditionally consumed at the tournament. Unlike other tournaments, advertising is minimal and low key from official suppliers such as Slazenger and Rolex. The relationship with Slazenger is the world's longest-running sporting sponsorship, providing balls for the tournament since 1902.\n\nDue to the COVID-19 pandemic, 2020 Wimbledon was cancelled, the first cancellation of the tournament since World War II. The rescheduled 134th edition was staged from 28 June 2021 to 11 July 2021, following from the 2020 cancellation. The 135th edition was played between 27 June 2022 and 10 July 2022, and regularly scheduled play occurred on the middle Sunday for the first time. It marks the centenary of the inaugural championships staged at the Centre Court. The ATP, ITF, and WTA did not award ranking points for the 2022 tournament, due to controversy over the tournament excluding players representing Russia and Belarus.\n\nThe 2023 Wimbledon Championships will be the 136th staging and will run from 3 July 2023 to 16 July 2023 and it will be the first event of King Charles III since the death of the former patron, Queen Elizabeth II on 8 September 2022.",

        "answer": "They are obtained by training on the in-domain data.",
        "evidence": "Experimental Setup We follow BIBREF28 and train domain-specific models for all domains. We then evaluate each model across the different domain test sets, enabling us to understand the effect of different domains on the downstream MT performance and to set up strong baselines for data selection experiments. We also train a general-domain model using the available data from all domains, as it is also a common approach in multi-domain scenarios BIBREF29. In all experiments we use a similar Transformer BIBREF36 model, and only control for the training data. More details on the exact training and hyperparameter settings for the NMT models are available in the supplementary material.\nResults The results for the cross-domain evaluation are available in Table TABREF28. In most cases, the best results for each domain are obtained by training on the in-domain data. Training on all the available data helped mostly for the Koran test set. This is expected as the training data for this domain is considerably smaller than the training data for rest of the domains (Table TABREF24). We can also see that more data is not necessarily better BIBREF37: while the subtitles corpus is the largest of all 5 and includes 500,000 sentence pairs, it is second to last in performance as measured by the average BLEU across all test sets.\nCross-Domain BLEU vs. Cluster Proximity An interesting observation can be made with respect to the visual analysis of the domain clusters as depicted in Figure FIGREF15: as the Medical cluster (in Yellow), Law cluster (in Purple) and IT cluster (in Red) are close to each other in the embedding space, their cross-domain BLEU scores are also higher. For example, note how in the results for the Medical domain-specific model (first row in Table TABREF28), the BLEU scores on the Law and IT test sets are much higher in comparison to those on the Koran and Subtitles test sets, which clusters are farther away in the visualized embedding space. Similarly, as the Subtitles cluster (Blue) is closer to the Koran cluster (Green), the highest cross-domain BLEU score on the Koran test set is from the Subtitles model. To further quantify this phenomenon, we plot and measure Pearson's correlation between the cosine similarity of the centroids for the English BERT-based dev sentence representations for each domain pair, and the cross-domain BLEU score for this domain pair. This is shown in Figure FIGREF29. We can see the general trend where the closer the domain centroids are (with a similarity of 1 for training and evaluating on the same domain), the higher the cross-domain BLEU is between those domains, resulting in a Pearson's correlation of 0.81 (strong correlation). This suggests that such preliminary visual analysis can be a useful tool for understanding the relationship between diverse datasets, and motivates the use of pre-trained language model representations for domain data selection in MT.\nIn most cases, the best results for each domain are obtained by training on the in-domain data.",

        "question": "What model do they use in their method?",
        "answer": "A class language model (LM) with class tag.",
        "evidence": "Speech input is now a common feature for smart devices. In many cases, the user's query involves entities such as a name from a contact list, a location, or a music title. Recognizing entities is particularly challenging for speech recognition because many entities are infrequent or out of the main vocabulary of the system. One way to improve performance is such cases is through the use of a personal language model (LM) which contains the expected user-specific entities. Because each user can have their own personalized LM, it is vital that the speech decoder be able to efficiently load the model on the fly, so it can be used in decoding, without any noticeable increase in latency.\nMany state-of-the-art speech recognition decoders are based on the weighted finite state transducer (WFST) paradigm BIBREF0, BIBREF1. A conventional WFST decoder searches a statically composed $H C L G$ graph, where $H$ is the graph that translates HMM states to CD phones, $C$ translates CD phones to graphemes, $L$ translates graphemes to words and $G$ is graph that represents the language model. Using a statically composed graph has two limitations. First, it is both compute and memory intensive when the vocabulary and LM are large. Second, the static graph approach makes it hard to handle personalized language models BIBREF2. Many common tasks a user may want to perform with a voice assistant such as making phone calls, messaging to a specific contact or playing favorite music require a personalized language model. A dynamic WFST decoder is better suited for such cases. As denoted in Eq (DISPLAY_FORM1), in a dynamic WFST decoder, $HCL$ is composed and optimized offline, while $G$ is composed on the fly with lazy (on-demand) composition, denoted as $\\circ $.\nTo handle dynamic entities, a class LM $G_c$ is normally used as background $G$ and a personalized LM $G_p$ is replaced on-the-fly, before applying lazy composition.\nSince the non-terminal states are composed on-the-fly, it means the states of recognition FST will also contain personalized information that cannot be used by other users or service threads.\nIn previous work, a method was proposed to do a pre-initialized composition for a non-class LM BIBREF3. However, it the dynamic part is still expanded on-the-fly. In this work, we propose two improvements in order to best leverage class language models. First, we use simpler methods for pre-initialization which do not need to pre-generate decoder state statistics. Second, we propose a two-layer pre-initialization mechanism that also avoids performing dynamic expansion on per user basis. In the two-layer pre-initialization method, we make use of a class LM with class tag. We build a personalized FST that contains the members of the class for each user. Using the FST replacement algorithm, we obtain a personalized language transducer BIBREF4. We perform a pre-composition for all FST states whose transitions do not contain class tags. By doing so, the actual on-demand composition is only required for the states in personalized FST. For a multi-threaded service, the pre-composed FST can be shared by all threads, since it does not contain personalized FST states (non-terminals). The personalized part will be shared for all utterances from the same user, which will take full advantage of memory usage.\nUnlike the previous pre-initialization approach that is based on calculating the state statistics BIBREF3, our simplified pre-initialization methods do not rely on pre-calculated state frequencies. Instead, we directly expand the graph with breadth-first search or through a data-driven approach where a small numbers of utterances are processed by the decoder offline. We found that both methods are effective, but the data-driven approach outperforms the breadth first search algorithm. Both methods can be combined to achieve the best performance. Through a series of experiments on a speech recognition task for the calling domain, we found that pre-initialization on the public graph speeds up the decoding time by a factor of three. Futhermore, sharing the private graph further reduces decoding time and results in factor of five improvement in efficiency.\nIn the two-layer pre-initialization method, we make use of a class LM with class tag.",

        "question": "Why do we have a threefold repetition rule in chess?",
        "evidence": "In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times during the game. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position. Two positions are by definition \"the same\" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture en passant is the same. The repeated positions need not occur in succession. The reasoning behind the rule is that if the position occurs three times, no real progress is being made and the game could hypothetically continue indefinitely.\n\nThe game is not automatically drawn if a position occurs for the third time – one of the players, on their turn, must claim the draw with the arbiter. The claim must be made either before making the move which will produce the third repetition, or after the opponent has made a move producing a third repetition. By contrast, the fivefold repetition rule requires the arbiter to intervene and declare the game drawn if the same position occurs five times, needing no claim by the players.",

        "question": "What does the Meta-NLG base on?",
        "answer": "It is based on MAML.",
        "evidence": "As an essential part of a task-oriented dialogue system BIBREF0 , the task of natural language generation (NLG) is to produce a natural language utterance containing the desired information given a semantic representation consisting of dialogue act types with a set of slot-value pairs. Conventional methods using hand-crafted rules often generates monotonic utterances and it requires substantial amount of human engineering work. Recently, various neural approaches BIBREF1 , BIBREF2 , BIBREF3 have been proposed to generate accurate, natural and diverse utterances. However, these methods are typically developed for particular domains. Moreover, they are often data-intensive to train. The high annotation cost prevents developers to build their own NLG component from scratch. Therefore, it is extremely useful to train a NLG model that can be generalized to other NLG domains or tasks with a reasonable amount of annotated data. This is referred to low-resource NLG task in this paper.\nRecently, some methods have been proposed for low-resource NLG tasks. Apart from the simple data augmentation trick BIBREF4 , specialized model architectures, including conditional variational auto-encoders (CVAEs, BIBREF3 , BIBREF5 , BIBREF6 ) and adversarial domain adaptation critics BIBREF5 , have been proposed to learn domain-invariant representations. Although promising results were reported, we found that datasets used by these methods are simple which tend to enumerate many slots and values in an utterance without much linguistic variations. As a consequence, over-fitting the slots and values in the low-resource target domain could even outperform those versions trained with rich source domain examples BIBREF6 . Fortunately, there is a new large-scale dialog dataset (MultiWoz, BIBREF7 ) that contains a great variety of domains and linguistic patterns that allows us to conduct extensive and meaningful experimental analysis for low-resource NLG tasks.\nIn this paper, instead of casting the problem as model-based approaches, we propose a generalized optimization-based meta-learning approach to directly enhance the optimization procedure for the low-resource NLG task. We start by arguing that a recently proposed model-agnostic meta-learning algorithm (MAML, BIBREF8 ) is a nice fit to the low-resource NLG task. Then, we proposed a generalized NLG algorithm called Meta-NLG based on MAML by viewing languages in different domains or dialog act types as separate Meta NLG tasks. Following the essence of MAML, the goal of Meta-NLG is to learn a better initialization of model parameters that facilitates fast adaptation to new low-resource NLG scenarios. As Meta-NLG is model-agnostic as long as the model can be optimized by gradient descent, we could apply it to any existing NLG models to optimize them in a way that adapt better and faster to new low-resource tasks.\nThe main contribution of this paper is two-fold:\nThen, we proposed a generalized NLG algorithm called Meta-NLG based on MAML by viewing languages in different domains or dialog act types as separate Meta NLG tasks.",

        "question": "Given a reference text about Magic the Gathering decks, please suggest cards I should consider in a Midrange deck.",
        "evidence": "Most classifications of Magic the Gathering decks begin from one of four major strategies: aggro, control, combo and midrange.\n\nAggro\nAggro (short for \"aggressive\") decks attempt to reduce their opponents from 20 life to 0 life as quickly as possible, rather than emphasize a long-term game plan. Aggro decks focus on converting their cards into damage; they prefer to engage in a race for tempo rather than a card advantage-based attrition war. Aggro generally relies upon creatures as its accumulative source of damage. Aggro decks can quickly overwhelm unprepared opponents and proceed to eke out the last bit of damage they need to end the game. Aggro decks also generally have access to disruptive elements, which can inhibit the opponent's attempts to respond.\n\nExample cards: Savannah Lions, Bitterblossom, Lightning Bolt, Rogue Elephant, Incinerate\nExample decks:\nWhite Weenie, which uses small, efficient creatures such as Savannah Lions, Icatian Javelineers, and Mother of Runes\nAffinity, which uses the affinity mechanic and large numbers of artifacts to quickly play spells such as Thoughtcast and Frogmite, while efficiently dealing damage using Disciple of the Vault and Arcbound Ravager.\nZoo, which uses low-cost, high power creatures such as Tarmogoyf and Wild Nacatl to kill the opponent quickly.\nSligh, which utilizes its mana as efficiently as possible to kill the opponent quickly, using low-cost cards such as Jackal Pup and Lightning Bolt.\nSuicide Black, which uses efficient but dangerous cards that cost life such as Thoughtseize, Dark Confidant, Grim Tutor, and Bitterblossom. Suicide Black epitomizes Black's philosophy—win at all costs—and treats even its life total as an expendable resource.\nControl\nControl decks avoid racing. They attempt to slow the game down by executing an attrition plan. As the game progresses, control decks are able to take advantage of their slower, more powerful, cards. The primary strength of control decks is their ability to devalue the opponent’s cards. They do this in four ways:\n\nAnswering threats at a reduced cost. Given the opportunity, Control decks can gain card advantage by answering multiple threats with one spell (\"clearing\"/\"wiping\" the board), stopping expensive threats with cheaper spells, and drawing multiple cards or forcing the opponent to discard multiple cards with one spell.\nNot playing threats to be answered. By playing few proactive spells of their own, control decks gain virtual card advantage by reducing the usefulness of opposing removal cards.\nDisrupting synergies. Even if control decks do not deal with every threat directly, they can leave out whichever ones stand poorly on their own; e.g., an enchantment which gives a bonus to creatures will never need attention if all enemy creatures are quickly neutralized.\nDragging the game out past opposing preparations. An opponent's faster, efficient cards will become less effective over time.\nExample cards: Force of Will, Duress, Wrath of God, Pernicious Deed, Void\nExample decks:\nTezzeret Control, which controls the game using counterspells such as Mana Drain, builds card advantage with cards such as Dark Confidant, and ends the game using Tezzeret the Seeker to find Time Vault and activate it for infinite turns.\nMono Blue Control, which uses a heavy suite of counterspells alongside card-drawing such as Thirst for Knowledge, removal such as Echoing Truth, and a win condition such as Tezzeret the Seeker. This class of deck is nicknamed \"Draw-Go,\" because most of its players' spells are instants designed to be played during his or her opponents' turns.\nBlue-White Control, which is similar to Mono-Blue Control, but features more board-control cards such as Wrath of God, and Pacifism.\nPsychatog, supplemented by card-drawing like Fact or Fiction and a number of disruptive spells.\nAstral Slide, which uses large numbers of cards with cycling, including those with added benefits such as Eternal Dragon and Slice and Dice, to power Astral Slide and Lightning Rift.\nMono-Black Control, which uses removal spells such as Innocent Blood and Barter in Blood to control the board, and Cabal Coffers to kill the opponent with spells such as Consume Spirit. It can also use cards like Underworld Dreams to put the opponent on a timer.\nThe Deck, which uses card drawing such as Fact or Fiction and deck searching cards such as Demonic Tutor to find powerful cards that are highly effective against particular strategies (such as The Abyss, Diabolic Edict, and Balance), alongside a Blue base of counterspells to control the game and obtain an insurmountable lead.\nCombo\nCombo decks use the interaction of two or more cards (a \"combination\") to create a powerful effect that either wins the game immediately or creates a situation that subsequently leads to a win. Combo decks value consistency, speed, and resilience: the deck should be reliable enough to produce the combo on a regular basis, the deck should be able to use the combo fast enough to win before the opponent, and the deck should be able to withstand disruption and still win.\n\nMany decks have smaller, combo-like interactions between their cards, which is better described as synergy.\n\nExample cards: Flash, Tendrils of Agony, Empty the Warrens, Aluren, Painter's Servant.\nExample decks:\nThe Perfect Storm, which utilizes Dark Ritual and artifact mana to draw cards and fuel a lethal Tendrils of Agony, all the while disrupting the opponent with Duress and Force of Will.\nPainter Combo, which uses Painter's Servant and chooses Blue to permit Red Elemental Blast to destroy any permanent or counter any spell, while also allowing Grindstone to put the opponent's entire library into their graveyard.\nWorldgorger Dragon Combo, which revolves around the infinite loop triggered when Worldgorger Dragon is animated from the graveyard using an enchantment such as Animate Dead. The loop generates mana and card drawing which is then used to end the game.\nBelcher Combo, which uses free and efficient mana acceleration to play and activate Goblin Charbelcher, preferably on the first turn. Because the deck has two or fewer lands, one activation of Goblin Charbelcher will almost always kill the opponent.\nHulk-Flash, which is dedicated to casting Flash and putting a Protean Hulk into play and then into the graveyard, allowing the player to find a combination of creatures which will kill the opponent instantly. Summoner's Pact and Merchant Scroll are used to find the combo pieces, while Force of Will and Pact of Negation protect the combo.\nSteel City Vault, which uses \"Draw 7\" spells such as Timetwister to rapidly assemble the Time Vault-Voltaic Key combo for infinite turns. The deck also uses several cards such as Force of Will and Ancient Grudge to efficiently deal with Null Rod, the most effective answer to the Vault-Key combo.\nHexmage Depths, which uses Vampire Hexmage to inexpensively remove the counters from Dark Depths and put a flying, indestructible 20/20 creature token into play as early as the first turn.\nMidrange\nA typical midrange deck has an early game plan of mana ramp and control, but begins to play threats once it reaches four to six mana. A midrange deck will often seek to play a reactive, attrition-based game against aggro decks and a more proactive, tempo-based game against control decks. Colloquially, this is referred to as \"going bigger\" than aggro and \"getting in under\" control.\n\nExample cards: Huntmaster of the Fells Thragtusk, Sakura-Tribe Elder\nExample decks:\nJund Midrange (BRG), a powerful and flexible deck with virtually zero bad matchups thanks to the access of the most powerful cards that each color can offer: black gives Liliana of the Veil and powerful discard cards like Thoughtseize and Inquisition of Kozilek, red a reliable removal in Lightning Bolt and the green some of the best creatures like Tarmogoyf and Scavenging Ooze.\nAbzan Midrange (WBG), which is similar to Jund, but trades speed for powerful white based cards like Path to Exile, Lingering Souls and Siege Rhino.\nJeskai Midrange (UWR), which has more control elements, using Sphinx's Revelation to draw into a very large number of cards and Assemble the Legion to end up swarming the board with tokens.\nTemur Emerge (GUR), which leverages the Emerge mechanic introduced in Eldritch Moon to efficiently use ramp creatures such as Pilgrim's Eye and Primal Druid for their land-smoothing abilities while sacrificing them to Emerge board-stalling threats such as Elder Deep-Fiend as early as turn 4, also filling the graveyard to make Emrakul, the Promised End playable on turn 7.\nTron, which tries to build the triplet of lands known as \"Urzatron\" (Urza's Tower, Urza's Mine and Urza's Power Plant) as quickly as possible and then uses the massive amount of mana to play powerful cards like Karn Liberated and Wurmcoil Engine as early as turn 3.",

We present the annotator with five words – four drawn from one cluster and one drawn randomly from the domain vocabulary – and we ask them to pick out the intruder. The intuition is that if the cluster is coherent, then an observer should be able to identify the out-of-cluster word as the intruder. For both domains, we report results on all clusters and on the top 8, ranked by ascending normalized sum of squared errors, which can be seen as a prediction of coherence. In the celebrity domain, annotators identified the out-of-cluster word 73% of the time in the top-8 and 53% overall. In the professor domain, annotators identified it 60% of the time in the top-8 and 49% overall. As expected, top-8 performance in both domains does considerably better than overall, but at all levels the precision is significantly above the random baseline of 20%.\nTo test cluster labels, we present the annotator with a label and a word, and we ask them whether the word falls under the concept. The concept is a potential cluster label and the word is either a word from that cluster or drawn randomly from the domain vocabulary. For a good label, the rate at which in-cluster words fall under the label should be much higher than the rate at which out-of-cluster words fall under. In our experiments, we tested the top 4 predicted labels and the centroid of the cluster as a strong baseline label. The centroid achieved an in-cluster rate of .60 and out-of-cluster rate of .18 (difference of .42). Our best performing predicted label achieved an in-cluster rate of .65 and an out-of-cluster rate of .04 (difference of .61), thus outperforming the centroid on both rates and increasing the gap between rates by nearly 20 points.

        "question": "What does the model consist of?",
        "answer": "The model consists of 4 modules: 1. Template extraction. 2. Template clustering. 3. Summary rewriting. 4. Summary selection.",
        "evidence": "Our motivation for using templates for data synthesis is that seq2seq synthesis models (as discussed in related work) tend to generate irrelevant and repeated words BIBREF17, while templates can produce more coherent and concise output. Also, extracting templates can be done either manually or automatically typically by training a few parameters or even doing no training, then external information in the form of keywords or snippets can be populated into the templates with the help of more sophisticated models. Accordingly, using templates can be very tempting for domains with limited resources such as ours.\nModel Structure. The model consists of 4 modules:\n1. Template extraction: To convert human summaries into templates, we remove keywords in the summary to leave only non-keywords. We use Rapid Automatic Keyword Extraction (RAKE) BIBREF18 to identify keywords.\n2. Template clustering: Upon converting human summaries into templates, we cluster them into $N$ clusters with the goal of using any template from the same cluster interchangeably. A template is first converted into embeddings using a pretrained BERT model BIBREF19, where template embedding is constructed by average pooling word embeddings. Templates are then clustered using k-medoid.\n3. Summary rewriting: An encoder-attention-decoder with pointer network is trained to perform the rewriting task. The model is trained to inject keywords into a template and perform rewriting into a coherent paragraph. The produced rewrites are considered as candidate summaries.\n4. Summary selection: After producing candidate summaries, we need to pick the best ones. We argue that the best candidates are those that are coherent and also convey the same meaning as the original human summary. We thus use a hybrid metric to score candidates, where the metric is a weighted sum of two scores and is calculated using Equations 1, 2, and 3. Eq.1 measures coherency using a language model (LM), Eq.2 measures how close a candidate is to a human summary using ROUGE scores, while Eq.3 picks the highest scored $N$ candidates as the final synthetic set.\nCS and HS are a candidate and human summary. $P(w)$ is the probability of word $w$ using a language model. $\\alpha , \\beta $ are weighting parameters. In this work we use $\\alpha =\\beta =1$ for all experiments. $R_{i}(CS,HS)$ is ROUGE-i score between CS and HS for i=1, 2, and $l$.\nModel Training. Before using the synthesis model, some of the constructing modules (rewriting module, scoring LM) need training. To train the rewriting model, we use another dataset consisting of a set of samples, where each sample can be a text snippet (sentence, paragraph, etc.). For each sample, keywords are extracted using RAKE, then removed. The keywords plus the sample with no keywords are then passed to the rewriting model. The training objective of this model is to reconstruct the original sample, which can be seen as trying to inject extracted keywords back into a template. Model Usage. To use the synthesis model to generate new samples, the set of human summaries are fed to the model, passing through the sub-modules in the following order:\n1. Human summaries first pass through the template extraction module, converting each summary $s_i$ into template $t_i$ and the corresponding keywords $kw_i$.\n2. Templates are then passed to the clustering module, producing a set of clusters. Each cluster $C$ contains a number of similar templates.\n3. For each template $t_i$ and corresponding keywords $kw_i$ from step 1, find the cluster $C_i$ that contains the template $t_i$, then pass the set of templates within that clusters $\\lbrace t_j\\rbrace \\forall {j},$ if $t_j \\in C_i$ alongside the keywords $kw_i$ to the summary rewriting module. This will produce a set of candidate summaries.\n4. The summary selection module scores and selects the highest $N$ candidates as the synthetic summaries.\nThe model consists of 4 modules: 1. Template extraction: To convert human summaries into templates, we remove keywords in the summary to leave only non-keywords. We use Rapid Automatic Keyword Extraction (RAKE) (Rose et al. 2010) to identify keywords. 2. Template clustering: Upon converting human summaries into templates, we cluster them into N clusters with the goal of using any template from the same cluster interchangeably. A template is first converted into embeddings using a pretrained BERT model5 (Devlin et al. 2018), where template embedding is constructed by average pooling word embeddings. Templates are then clustered using k-medoid. 3. Summary rewriting: An encoder-attention-decoder with pointer network is trained to perform the rewriting task. The model is trained to inject keywords into a template and perform rewriting into a coherent paragraph. The produced rewrites are considered as candidate summaries. 4.

Given a user-issued utterance (called a query in this paper), the computer needs to provide a reply to the query. In early years, researchers have developed various domain-oriented dialogue systems, which are typically based on rules or templates BIBREF4 , BIBREF5 , BIBREF6 . Recently, open-domain conversation systems have attracted more and more attention in both academia and industry (e.g., XiaoBing from Microsoft and DuMi from Baidu). Due to high diversity, we can hardly design rules or templates in the open domain. Researchers have proposed information retrieval methods BIBREF7 and modern generative neural networks BIBREF8 , BIBREF9 to either search for a reply from a large conversation corpus or generate a new sentence as the reply.\nIn open-domain conversations, context information (one or a few previous utterances) is particularly important to language understanding BIBREF1 , BIBREF9 , BIBREF10 , BIBREF11 . As dialogue sentences are usually casual and short, a single utterance (e.g., “Thank you.” in Figure FIGREF2 ) does not convey much meaning, but its previous utterance (“...writing an essay”) provides useful background information of the conversation. Using such context will certainly benefit the conversation system.\nHowever, tracking all previous utterances as the context is unwise. First, commercial chat-bots usually place high demands on efficiency. In a retrieval-based system, for example, performing a standard process of candidate retrieval and re-ranking for each previous utterance may well exceed the time limit (which is very short, e.g., 500ms). Second, we observe that not all sentences in the current conversation session are equally important. The sentence “Want to take a walk?” is irrelevant to the current context, and should not be considered when the computer synthesizes the reply. Therefore, it raises the question of session segmentation in conversation systems.\nDocument segmentation for general-purpose corpora has been widely studied in NLP. For example, Hearst BIBREF12 proposes the TextTiling approach; she measures the similarity of neighboring sentences based on bag-of-words features, and performs segmentation by thresholding. However, such approaches are not tailored to the dialogue genre and may not be suitable for conversation session segmentation.\nIn this paper, we address the problem of session segmentation for open-domain conversations. We leverage the classic TextTiling approach, but enhance it with modern embedding-based similarity measures. Compared with traditional bag-of-words features, embeddings map discrete words to real-valued vectors, capturing underlying meanings in a continuous vector space; hence, it is more robust for noisy conversation corpora. Further, we propose a tailored method for word embedding learning. In traditional word embedding learning, the interaction between two words in a query and a reply is weaker than that within an utterance. We propose to combine a query and its corresponding reply as a “virtual sentence,” so that it provides a better way of modeling utterances between two agents.\nIn early years, researchers have developed various domain-oriented dialogue systems, which are typically based on rules or templates [5, 6, 7].",

        "evidence": "The task of generating natural language descriptions of structured data (such as tables) BIBREF2 , BIBREF3 , BIBREF4 has seen a growth in interest with the rise of sequence to sequence models that provide an easy way of encoding tables and generating text from them BIBREF0 , BIBREF1 , BIBREF5 , BIBREF6 .\nFor text generation tasks, the only gold standard metric is to show the output to humans for judging its quality, but this is too expensive to apply repeatedly anytime small modifications are made to a system. Hence, automatic metrics that compare the generated text to one or more reference texts are routinely used to compare models BIBREF7 . For table-to-text generation, automatic evaluation has largely relied on BLEU BIBREF8 and ROUGE BIBREF9 . The underlying assumption behind these metrics is that the reference text is gold-standard, i.e., it is the ideal target text that a system should generate. In practice, however, when datasets are collected automatically and heuristically, the reference texts are often not ideal. Figure FIGREF2 shows an example from the WikiBio dataset BIBREF0 . Here the reference contains extra information which no system can be expected to produce given only the associated table. We call such reference texts divergent from the table.\nWe show that existing automatic metrics, including BLEU, correlate poorly with human judgments when the evaluation sets contain divergent references (§ SECREF36 ). For many table-to-text generation tasks, the tables themselves are in a pseudo-natural language format (e.g., WikiBio, WebNLG BIBREF6 , and E2E-NLG BIBREF10 ). In such cases we propose to compare the generated text to the underlying table as well to improve evaluation. We develop a new metric, PARENT (Precision And Recall of Entailed N-grams from the Table) (§ SECREF3 ). When computing precision, PARENT effectively uses a union of the reference and the table, to reward correct information missing from the reference. When computing recall, it uses an intersection of the reference and the table, to ignore extra incorrect information in the reference. The union and intersection are computed with the help of an entailment model to decide if a text n-gram is entailed by the table. We show that this method is more effective than using the table as an additional reference.

        "question": "Why is macro-averaged F-score chosen in the study?",
        "answer": "To reduce the possibility of misleading and to improve accuracy on the basis of imbalanced datasets.",
        "evidence": "A common issue for many Natural Language Processing (NLP) classification tasks is class imbalance, the situation where one of the class categories comprises a significantly larger proportion of the dataset than the other classes. It is especially prominent in real-world datasets and complicates classification when the identification of the minority class is of specific importance.\nModels trained on the basis of minimising errors for imbalanced datasets tend to more frequently predict the majority class; achieving high accuracy in such cases can be misleading. Because of this, the macro-averaged F-score, chosen for this competition, is a more suitable metric as it weights the performance on each class equally.\nAs class imbalance is a widespread issue, multiple techniques have been developed that help alleviate it BIBREF7, BIBREF8, by either adjusting the model (e.g. changing the performance metric) or changing the data (e.g. oversampling the minority class or undersampling the majority class).\nCost-sensitive classification can be used when the “cost” of mislabelling one class is higher than that of mislabelling other classes BIBREF9, BIBREF10. For example, the real cost to a bank of miscategorising a large fraudulent transaction as authentic is potentially higher than miscategorising (perhaps only temporarily) a valid transaction as fraudulent. Cost-sensitive learning tackles the issue of class imbalance by changing the cost function of the model such that misclassification of training examples from the minority class carries more weight and is thus more `expensive'. This is achieved by simply multiplying the loss of each example by a certain factor. This cost-sensitive learning technique takes misclassification costs into account during model training, and does not modify the imbalanced data distribution directly.\nCommon methods that tackle the problem of class imbalance by modifying the data to create balanced datasets are undersampling and oversampling. Undersampling randomly removes instances from the majority class and is only suitable for problems with an abundance of data. Oversampling means creating more minority class instances to match the size of the majority class. Oversampling methods range from simple random oversampling, i.e. repeating the training procedure on instances from the minority class, chosen at random, to the more complex, which involves constructing synthetic minority-class samples. Random oversampling is similar to cost-sensitive learning as repeating the sample several times makes the cost of its mis-classification grow proportionally. Kolomiyets et al. kolomiyets2011model, Zhang et al. zhang2015character, and Wang and Yang wang2015s perform data augmentation using synonym replacement, i.e. replacing random words in sentences with their synonyms or nearest-neighbor embeddings, and show its effectiveness on multiple tasks and datasets. Wei et al. wei2019eda provide a great overview of `easy' data augmentation (EDA) techniques for NLP, including synonym replacement as described above, and random deletion, i.e. removing words in the sentence at random with pre-defined probability. They show the effectiveness of EDA across five text classification tasks. However, they mention that EDA may not lead to substantial improvements when using pre-trained models. In this work we test this claim by comparing performance gains of using cost-sensitive learning versus two data augmentation methods, synonym replacement and random deletion, with a pre-trained BERT model.\nMore complex augmentation methods include back-translation BIBREF11, translational data augmentation BIBREF12, and noising BIBREF13, but these are out of the scope of this study.\nThe sentence level classification task is an imbalanced binary classification problem that we address using BERT BIBREF0. We use BERTBASE, uncased, which consists of 12 self-attention layers, and returns a 768-dimension vector that representation a sentence. So as to make use of BERT for sentence classification, we include a fully connected layer on top of the BERT self-attention layers, which classifies the sentence embedding provided by BERT into the two classes of interest (propaganda or non-propaganda).\nWe attempt to exploit various data augmentation techniques to address the problem of class imbalance. Table TABREF17 shows the results of our experiments for different data augmentation techniques when, after shuffling the training data, we train the model on 75% of the training data and test it on the remaining 25% of the training data and the development data.\nWe observe that BERT without augmentation consistently outperforms BERT with augmentation in the experiments when the model is trained on 75% of the training data and evaluated on the rest, i.e trained and evaluated on similar data, coming from the same distribution. This is consistent with observations by Wei et al. wei2019eda that contextual word embeddings do not gain from data augmentation. The fact that we shuffle the training data prior to splitting it into training and testing subsets could imply that the model is learning to associate topic words, such as `Mueller', as propaganda. However, when we perform model evaluation using the development set, which is dissimilar to the training, we observe that synonym insertion and word dropping techniques also do not bring performance gains, while random oversampling increases performance over base BERT by 4%. Synonym insertion provides results very similar to base BERT, while random deletion harms model performance producing lower scores. We believe that this could be attributed to the fact that synonym insertion and random word dropping involve the introduction of noise to the data, while oversampling does not. As we are working with natural language data, this type of noise can in fact change the meaning of the sentence. Oversampling on the other hand purely increases the importance of the minority class by repeating training on the unchanged instances.\nSo as to better understand the aspects of oversampling that contribute to these gains, we perform a class-wise performance analysis of BERT with/without oversampling. The results of these experiments (Table TABREF18) show that oversampling increases the overall recall while maintaining precision. This is achieved by significantly improving the recall of the minority class (propaganda) at the cost of the recall of the majority class.\nSo far we have been able to establish that a) the training and test sets are dissimilar, thus requiring us to generalise our model, b) oversampling provides a method of generalisation, and c) oversampling does this while maintaining recall on the minority (and thus more interesting) class.\nGiven this we explore alternative methods of increasing minority class recall without a significant drop in precision. One such method is cost-sensitive classification, which differs from random oversampling in that it provides a more continuous-valued and consistent method of weighting samples of imbalanced training data; for example, random oversampling will inevitably emphasise some training instances at the expense of others. We detail our methods of using cost-sensitive classification in the next section. Further experiments with oversampling might have provided insights into the relationships between these methods, which we leave for future exploration.\nModels trained on the basis of minimising errors for imbalanced datasets tend to more frequently predict the majority class; achieving high accuracy in such cases can be misleading. Because of this, the macro-averaged F-score, chosen for this competition, is a more suitable metric as it weights the performance on each class equally.",

Typically, such benchmarks BIBREF0 are composed of short pieces of text commenting on politicians or public issues and are manually annotated with their stance towards a target entity (e.g. Climate Change, or Trump). However, they are limited in scope on multiple levels BIBREF1.\nFirst of all, it is questionable how well current stance detection methods perform in a cross-lingual setting, as the multilingual datasets available today are relatively small, and specific to a single target BIBREF2, BIBREF3. Furthermore, specific models tend to be developed for each single target or pair of targets BIBREF4. Concerns have been raised that cross-target performance is often considerably lower than fully supervised performance BIBREF1.\nIn this paper we propose a much larger dataset that combines multilinguality and a multitude of topics and targets. x-stance comprises more than 150 questions concerning Swiss politics and more than 67k answers given in the last decade by candidates running for political office in Switzerland.\nQuestions are available in four languages: English, Swiss Standard German, French, and Italian. The language of a comment depends on the candidate's region of origin.\nWe have extracted the data from the voting advice application Smartvote.

        "evidence": "Machine reading comprehension and question answering has becomes a crucial application problem in evaluating the progress of AI system in the realm of natural language processing and understanding BIBREF0 . The computational linguistics communities have devoted significant attention to the general problem of machine reading comprehension and question answering.\nHowever, most of existing reading comprehension tasks only focus on shallow QA tasks that can be tackled very effectively by existing retrieval-based techniques BIBREF1 . For example, recently we have seen increased interest in constructing extractive machine reading comprehension datasets such as SQuAD BIBREF2 and NewsQA BIBREF3 . Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nIn this work, we propose dual co-matching network (DMN) which incorporates all the pairwise relationships among the { P , Q , A } triplet bidirectionally.",

        "evidence": "The term dead man zone was coined by members of the CSIRO research team in Australia who were investigating the spread of bushfires (Project Vesta). The dead man zone is approximately 8 kilometres (5.0 mi) around the fire that is likely to burn. This dead man zone can be a safety net for firefighters if the fire is moving at a high speed. The dead man zone can also be prepared in a way that slows down the fire. Firefighters can get outside the dead man zone safely without seeing what the fire is going to do and develop a plan of attack or defense upon the fire's next move. If the dead man zone is not used, wind change can sneak up on the firefighters and resulting in potentially unsafe distances where they are not able to defend themselves. This can be a life or death situation if not approached properly, and there have been examples of firefighters that became trapped and ultimately killed in Australia. Project Vesta, headed by scientist Phil Cheney, found that when the wind changes direction, the line of fire will move out at its maximum rate of spread almost immediately, and that the spread speed was nearly three times what was previously thought.

However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the Sun to the observer's eye.\nIn a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.\nIn a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc.

        "question": "What is machine learning, and when did it first emerge?",
        "evidence": "Machine learning (ML) is a field of inquiry devoted to understanding and building methods that \"learn\" – that is, methods that leverage data to improve performance on some set of tasks. It is seen as a part of artificial intelligence.\n\nMachine learning algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning algorithms are used in a wide variety of applications, such as in medicine, email filtering, speech recognition, agriculture, and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks.\n\nA subset of machine learning is closely related to computational statistics, which focuses on making predictions using computers, but not all machine learning is statistical learning. The study of mathematical optimization delivers methods, theory and application domains to the field of machine learning. Data mining is a related field of study, focusing on exploratory data analysis through unsupervised learning.\n\nSome implementations of machine learning use data and neural networks in a way that mimics the working of a biological brain.\n\nIn its application across business problems, machine learning is also referred to as predictive analytics.\n\nOverview\nLearning algorithms work on the basis that strategies, algorithms, and inferences that worked well in the past are likely to continue working well in the future. These inferences can be obvious, such as \"since the sun rose every morning for the last 10,000 days, it will probably rise tomorrow morning as well\". They can be nuanced, such as \"X% of families have geographically separate species with color variants, so there is a Y% chance that undiscovered black swans exist\".\n\nMachine learning programs can perform tasks without being explicitly programmed to do so. It involves computers learning from data provided so that they carry out certain tasks. For simple tasks assigned to computers, it is possible to program algorithms telling the machine how to execute all steps required to solve the problem at hand; on the computer's part, no learning is needed. For more advanced tasks, it can be challenging for a human to manually create the needed algorithms. In practice, it can turn out to be more effective to help the machine develop its own algorithm, rather than having human programmers specify every needed step.\n\nThe discipline of machine learning employs various approaches to teach computers to accomplish tasks where no fully satisfactory algorithm is available. In cases where vast numbers of potential answers exist, one approach is to label some of the correct answers as valid. This can then be used as training data for the computer to improve the algorithm(s) it uses to determine correct answers. For example, to train a system for the task of digital character recognition, the MNIST dataset of handwritten digits has often been used.\n\nHistory and relationships to other fields\nSee also: Timeline of machine learning\nThe term machine learning was coined in 1959 by Arthur Samuel, an IBM employee and pioneer in the field of computer gaming and artificial intelligence. The synonym self-teaching computers was also used in this time period.\n\nBy the early 1960s an experimental \"learning machine\" with punched tape memory, called CyberTron, had been developed by Raytheon Company to analyze sonar signals, electrocardiograms, and speech patterns using rudimentary reinforcement learning. It was repetitively \"trained\" by a human operator/teacher to recognize patterns and equipped with a \"goof\" button to cause it to re-evaluate incorrect decisions. A representative book on research into machine learning during the 1960s was Nilsson's book on Learning Machines, dealing mostly with machine learning for pattern classification. Interest related to pattern recognition continued into the 1970s, as described by Duda and Hart in 1973. In 1981 a report was given on using teaching strategies so that a neural network learns to recognize 40 characters (26 letters, 10 digits, and 4 special symbols) from a computer terminal.\n\nTom M. Mitchell provided a widely quoted, more formal definition of the algorithms studied in the machine learning field: \"A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P if its performance at tasks in T, as measured by P, improves with experience E.\" This definition of the tasks in which machine learning is concerned offers a fundamentally operational definition rather than defining the field in cognitive terms. This follows Alan Turing's proposal in his paper \"Computing Machinery and Intelligence\", in which the question \"Can machines think?\" is replaced with the question \"Can machines do what we (as thinking entities) can do?\".\n\nModern-day machine learning has two objectives, one is to classify data based on models which have been developed, the other purpose is to make predictions for future outcomes based on these models. A hypothetical algorithm specific to classifying data may use computer vision of moles coupled with supervised learning in order to train it to classify the cancerous moles.

The team which scores the most goals is declared the winner. In a formal game, each team has six skaters on the ice at a time, barring any penalties, one of whom is the goaltender. Ice hockey is a full contact sport, and is considered to be one of the more physically demanding sports.\n\nIce hockey is one of the sports featured in the Winter Olympics while its premiere international competition, the IIHF World Championships, are governed by the International Ice Hockey Federation (IIHF) for both men's and women's competitions.\n\nIn North America and parts of Europe the sport is known simply as hockey[citation needed]. However, in other countries, \"hockey\" usually refers to field hockey. In 1994 hockey was officially recognized as Canada's national winter sport.\n\nThe modern sport of ice hockey was developed in Canada, most notably in Montreal, where the first indoor game was played on March 3, 1875. Some characteristics of that game, such as the length of the ice rink and the use of a puck, have been retained to this day. Amateur ice hockey leagues began in the 1880s, and professional ice hockey originated around 1900. The Stanley Cup, emblematic of ice hockey club supremacy, was initially commissioned in 1892 as the \"Dominion Hockey Challenge Cup\" and was first awarded in 1893 to recognize the Canadian amateur champion and later became the championship trophy of the National Hockey League (NHL). In the early 1900s, the Canadian rules were adopted by the Ligue Internationale de Hockey Sur Glace, in Paris, France, the precursor of the IIHF. The sport was played for the first time at the Olympics during the 1920 Summer Olympics.\n\nWhile women also played during the game's early formative years, it was not until organizers began to officially remove body checking from female ice hockey beginning in the mid-1980s that it began to gain greater popularity, which by then had spread to Europe and a variety of other countries.

        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nWe extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese.",

See also our general response.\nPer request, we add two new synthetic family tree reasoning tasks with input and output ternary predicates to address this point: family-of-three and three-generations reasoning. Our model still achieves perfect accuracy on both tasks, while existing models except NLM cannot handle it.",
        "evidence": "Performing graph reasoning in large domains, such as predicting the relationship between two entities based on the input facts, is an important practical problem that arises in reasoning about molecular modeling, knowledge networks, and collections of objects in the physical world. The necessary inference rules are generally unknown and must be inferred from data, which in general are large. In this paper, we focus on learning neural networks for graph reasoning tasks. Consider the problem of learning a rule that explains the grandparent relationship. Given a dataset of labeled family relationship graphs, we aim to build machine-learning algorithms that can learn to predict a specific relationship (e.g., grandparent) based on other relationships, such as father(x, y) and mother(x, y).\nNeural Logic Machines (NLM; present a method for solving graph reasoning tasks with a structured neural network. NLMs keep track of hyperedge representations for all tuples consisting of up to B entities. Thus, they can infer more complex finitely-quantified logical relations than standard graph neural networks that only consider binary relationships between entities. However, there are two disadvantages of such a dense hypergraph representation. First, the training and inference of NLMs requires simultaneously considering all entities in a domain, such as all of the N people in a family relationship database. Second, they scale polynomially with respect to the number of entities considered in a single inference. Even inferring a single relation like grandparent requires O(N 3 ) time and space complexity. In practice, for large graphs, these limitations make the training and inference intractable and hinder the application of NLMs in large-scale real-world domains.\nTo address these two challenges, we present a novel framework, called Sparse and Local Neural Logic Machines (SpaLoc), for inducing sparse relational rules from data in large domains. Our key idea is to exploit locality and sparsity in data: determining a relationship between entities The overall pipeline of SpaLoc: a multi-layer neural network that applies to hypergraphs. I and V denote the index tensor and value tensor respectively. To facilitate training and inference in large domains, we employ a sub-graph sampling procedure and sparsification.\nusually only requires consideration of a small number of additional entities, and the resulting relation usually only holds for a small number of tuples of entities. Our contribution is three-fold. First, we develop a sparse tensor-based representation for representing hyperedge relationships among entities and making inferences about them. Second, during both training and inference, SpaLoc employs a sub-graph sampling technique based on an information-theoretic measure, information sufficiency, which quantifies the amount of information contained in a sub-graph with respect to whether a predicate is true for some tuple of entities. Since the sub-graph sampling may violate the closed-world assumption (i.e., the information in a sub-sampled graph may be insufficient in predicting the relationship between a pair of entities), we also use the information sufficiency measure to calibrate training labels. Third, to further speed up inference on large graphs, we encourage neural networks recover sparse relationships among objects by using a regularization term based on graph sparsity measurements.\nWe evaluate SpaLoc on two benchmarks: relational reasoning in synthetic datasets (family trees and general graph reasoning) and real-world knowledge-graph reasoning. First, we show that, with our sparsity regularization, the computation complexity for inference can be reduced to the same order as the optimal complexity, which significantly outperforms the base model NLM. Second, we show that training via sub-graph sampling and label calibration enables us to learn relational rules in real-world knowledge graphs with more than 10K nodes, whereas the original NLM can be barely applied to graphs with more than 100 nodes. Finally, SpaLoc achieves state-of-the-art performance on several real-world knowledge graph reasoning benchmarks.\nWe evaluate SpaLoc on two benchmarks: relational reasoning in synthetic datasets (family trees and general graph reasoning) and real-world knowledge-graph reasoning.\n****The inputs predicates are: Father(x, y), Mother(x, y), Son(x, y), Daughter(x, y).\nThe target predicates are:\n****\n• Family-of-three(x, y, z) = Father(x, y) ∧ Mother(x, z)\n• Three-generations(x, y, z) = Parent(x, y) ∧ Parent(y, z)",

The club has won 13 league titles (including one unbeaten title), a record 14 FA Cups, two League Cups, 16 FA Community Shields, one European Cup Winners' Cup, and one Inter-Cities Fairs Cup. In terms of trophies won, it is the third-most successful club in English football.\n\nArsenal was the first club from the South of England to join the Football League in 1893, and they reached the First Division in 1904. Relegated only once, in 1913, they continue the longest streak in the top division, and have won the second-most top-flight matches in English football history. In the 1930s, Arsenal won five League Championships and two FA Cups, and another FA Cup and two Championships after the war. In 1970–71, they won their first League and FA Cup Double. Between 1989 and 2005, they won five League titles and five FA Cups, including two more Doubles. They completed the 20th century with the highest average league position. Between 1998 and 2017, Arsenal qualified for the UEFA Champions League for nineteen consecutive seasons.\n\nHerbert Chapman, who changed the fortunes of Arsenal forever, won the club its first silverware, and his legacy led the club to dominate the 1930s decade; Chapman, however, died of pneumonia in 1934, aged 55. He helped introduce the WM formation, floodlights, and shirt numbers; he also added the white sleeves and brighter red to the club's jersey. Arsène Wenger is the longest-serving manager and won the most trophies. He won a record seven FA Cups, and his title-winning team set an English record for the longest top-flight unbeaten league run at 49 games between 2003 and 2004, receiving the nickname The Invincibles.\n\nIn 1886, munitions workers at the Royal Arsenal in Woolwich founded the club as Dial Square. In 1913 the club crossed the city to Arsenal Stadium in Highbury, becoming close neighbours of Tottenham Hotspur, and creating the North London derby. In 2006, they moved to the nearby Emirates Stadium. With an annual revenue of £340.3m in the 2019–20 season, Arsenal was estimated to be worth US$2.68 billion by Forbes, making it the world's eighth most valuable club, while it is one of the most followed on social media.The motto of the club has long been Victoria Concordia Crescit, Latin for \"Victory Through Harmony\".",

To this end, we leverage on an off-the-shelf entity linking system (ELS) to extract linked entities and propose Entity2Topic (E2T), a module easily attachable to a sequence-to-sequence model that transforms a list of entities into a vector representation of the topic of the summary. Current available ELS's are still not sufficiently effective, possibly introducing unresolved ambiguities and irrelevant entities. We resolve the imperfections of the ELS by (a) encoding entities with selective disambiguation, and (b) pooling entity vectors using firm attention.

In other words, theoretically, the meta-network considers the combination instead of just selecting the best one.  In addition, we have empirical observations in Table 5, InfoTS outperforms the variant that uses subsequence only (the last column). This comparison empirically shows that the meta-network learns to consider the combinations, which is better than any (single) candidate augmentation.",
        "evidence": "Previous time series contrastive learning methods generate augmentations with either rule of thumb guided by prefabricated human priors or tedious trial-and-errors, which are designed for specific datasets and learning tasks. In this part, we discuss how to adaptively select the optimal augmentations with a meta-learner network based on the proposed information-aware criteria. We can regard its choice of optimal augmentation as a kind of prior selection. We first choose a set of candidate transformations T, such as jittering and time warping. Each candidate transformation t i ∈ T is associated with an important weight p i ∈ (0, 1), inferring the probability of selecting transformation t i . For an instance x, the augmented instance v i through transformation t i can be computed by:\nConsidering multiple transformations, we pad all v i to be with the same length. Then, the adaptive augmented instance can be achieved by combing candidate ones, v = 1 |T| i v i . To enable the efficient optimization with gradient-based methods, we approximate discrete Bernoulli processes with binary concrete distributions. Specifically, we approximate a i in Eq. () with ∼ Uniform(0, 1)\nwhere σ(•) is the sigmoid function and τ is the temperature controlling the approximation. The rationality of such approximation is given in Appendix A. Moreover, with temperature τ > 0, the gradient ∂v ∂pi is well-defined. Therefore, our meta-network is end-to-end differentiable. Detailed algorithm is shown in Appendix B.\nConsidering multiple transformations, we pad all vi to be with the same length. Then, the adaptive augmented instance can be achieved by combing candidate ones****We compare performances of variants that each applies a single transformation to generate augmented instances in Table 5. From the table, we know that augmentation with subsequence benefits the most for the Electricity dataset. We visualize the weight updating process of InfoTS in Figure 8, with each line representing the normalized importance score of the corresponding transformation. The weight for subsequence increase with the epoch, showing that InfoTS tends to adopt subsequence as the optimal transformation. Consistency between accuracy performance and weight updating process demonstrates the effectiveness of InfoTS to adaptively select feasible transformations. Besides, as shown in Table 5, InfoTS outperforms the variant that uses subsequence only. This comparison shows that the meta-network learns to consider the combinations, which is better than any (single) candidate augmentation.",

Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.\nAuroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles.\nIn northern latitudes, the effect is known as the aurora borealis or the northern lights. The former term was coined by Galileo in 1619, from the Roman goddess of the dawn and the Greek name for the north wind. The southern counterpart, the aurora australis or the southern lights, has features almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. The aurora australis is visible from high southern latitudes in Antarctica, Chile, Argentina, South Africa, New Zealand and Australia. The aurora borealis is visible from areas around the Arctic such as Alaska, the Canadian Territories, Iceland, Greenland, Norway, Sweden, Finland and Siberia.

Speech was recorded in classrooms, whose equipment depended on each school. In general, around 20 students took the test together, at the same time and in the same classrooms, so it is quite common that speech of mates or teachers often overlaps with the speech of the student speaking in her/his microphone. Also, the type of microphone depends on the equipment of the school. On average, the audio signal quality is nearly good, while the main problem is caused by a high percentage of extraneous speech. This is due to the fact that organisers decided to use a fixed duration - which depends on the question - for recording spoken utterances, so that all the recordings for a given question have the same length. However, while it is rare that a speaker has not enough time to answer, it is quite common that, especially after the end of the utterance, some other speech (e.g. comments, jokes with mates, indications from the teachers, etc.) is captured. In addition, background noise is often present due to several sources (doors, steps, keyboard typing, background voices, street noises if the windows are open, etc). Finally, it has to be pointed out that many answers are whispered and difficult to understand.\nFLOAT SELECTED: Table 3: Spoken data collected during different evaluation campaigns.

        "evidence": "If the translation of a pronoun requires context beyond the current sentence (see the example in Figure FIGREF1 ), a natural extension of sentence-level NMT models is to condition the model prediction on this necessary context. In the following, we describe a number of existing approaches to making models “aware” of additional context.\nThe simplest possible extension is to translate units larger than sentences. BIBREF5 concatenate each sentence with the sentence that precedes it, for the source side of the corpus or both sides. All of their models are standard sequence-to-sequence models built with recurrent neural networks (RNNs), since the method does not require any architectural change. BIBREF11 use the same concatenation technique with a Transformer architecture BIBREF2 , and experiment with wider context.\nA number of works do propose changes to the NMT architecture. A common technique is to extend a standard encoder-decoder model by additional encoders for the context sentence(s), with a modified attention mechanism BIBREF6 , BIBREF9 , BIBREF8 . One aspect that differs between these works is the architecture of the encoder and attention. While BIBREF6 , BIBREF9 extend an RNN encoder-decoder with a second encoder that the decoder attends to, BIBREF8 extend the Transformer architecture with an encoder that is attended to by the main encoder. BIBREF8 also introduce parameter sharing between the main encoder and the context encoder, but do not empirically demonstrate its importance.\nWhile the number of encoded sentences in the previous work is fixed, BIBREF7 , BIBREF10 explore the integration of variable-size context through a hierarchical architecture, where a first-level RNN reads in words to produce sentence vectors, which are then fed into a second-level RNN to produce a document summary.\nApart from differences in the architectures, related work varies in whether it considers source context, target context, or both (see Table TABREF9 for an overview of language arcs and context types). Some work considers only source context, but for pronoun translation, target-side context is intuitively important for disambiguation, especially if the antecedent itself is ambiguous. In our evaluation, we therefore emphasize models that take into account both source and target context.\nOur experiments are based on models from BIBREF9 , who have released their source code. We extend their models with parameter sharing, which was shown to be beneficial by BIBREF8 . Additionally, we consider a concatenative baseline, similar to BIBREF5 , and Transformer-based models BIBREF8 .\nThis section describes several context-aware NMT models that we use in our experiments. They fall into two major categories: models based on RNNs and models based on the Transformer architecture BIBREF2 . We experiment with additional context on the source side and target side.\nThis section describes several context-aware NMT models that we use in our experiments.

        "evidence": "We applied this method to discover gender-associated words in both domains. In Table TABREF9, we present a sample of the most gender-associated nouns from the celebrity domain. Several themes emerge: for example, female celebrities seem to be more associated with appearance (“gown,” “photo,” “hair,” “look”), while male celebrities are more associated with creating content (“movie,” “film,” “host,” “director”). This echoes real-world trends: for instance, on the red carpet, actresses tend to be asked more questions about their appearance –- what brands they are wearing, how long it took to get ready, etc. –- while actors are asked questions about their careers and creative processes (as an example, see BIBREF31).\nTable TABREF9 also includes some of the most gender-associated verbs and adjectives from the professor domain. Female CS professors seem to be praised for being communicative and personal with students (“respond,” “communicate,” “kind,” “caring”), while male CS professors are recognized for being knowledgeable and challenging the students (“teach,”, “challenge,” “brilliant,” “practical”). These trends are well-supported by social science literature, which has found that female teachers are praised for “personalizing” instruction and interacting extensively with students, while male teachers are praised for using “teacher as expert” styles that showcase mastery of material BIBREF32.\nThese findings establish that there are clear differences in how people talk about women and men – even with Bonferroni correction, there are still over 500 significantly gender-associated nouns, verbs, and adjectives in the celebrity domain and over 200 in the professor domain. Furthermore, the results in both domains align with prior studies and real world trends, which validates that our methods can capture meaningful patterns and innovatively provide evidence at the large-scale. This analysis also hints that it can be helpful to abstract from words to topics to recognize higher-level patterns of gender associations, which motivates our next section on clustering.\nTable TABREF11 displays a sample of our results – we find that the clusters are coherent in context and the labels seem reasonable. In the next section, we discuss human evaluations that we conducted to more rigorously evaluate the output, but first we discuss the value of these methods toward analysis.\nAt the word-level, we hypothesized that in the celebrity domain, women were more associated with appearance and men with creating content. Now, we can validate those hypotheses against labeled clusters – indeed, there is a cluster labeled clothing that is 100% female (i.e. 100% words are female-associated), and a 80% male cluster labeled movie. Likewise, in the professor domain, we had guessed that women are associated with communication and men with knowledge, and there is a 100% female cluster labeled communication and a 89% male cluster labeled cognition. Thus, cluster labeling proves to be very effective at pulling out the patterns that we believed we saw at the word-level, but could not formally validate.\nThe clusters we mentioned so far all lean heavily toward one gender association or the other, but some clusters are interesting precisely because they do not lean heavily – this allows us to see where semantic groupings do not align exactly with gender association. For example, in the celebrity domain, there is a cluster labeled lover that has a mix of female-associated words (“boyfriend,” “beau,” “hubby”) and male-associated words (“wife,” “girlfriend”). Jointly leveraging cluster labels and gender associations allows us to see that in the semantic context of having a lover, women are typically associated with male figures and men with female figures, which reflects heteronormativity in society.\nThese findings establish that there are clear differences in how people talk about women and men – even with Bonferroni correction, there are still over 500 significantly gender-associated nouns, verbs, and adjectives in the celebrity domain and over 200 in the professor domain.",

        "answer": "A self-critic policy gradient method.",
        "evidence": "When there are a very large number of documents that need to be read in limited time, we often resort to reading summaries instead of the whole document. Automatically generating (abstractive) summaries is a problem with various applications, e.g., automatic authoring BIBREF0. We have developed automatic text summarization systems that condense large documents into short and readable summaries. It can be used for both single (e.g., BIBREF1, BIBREF2 and BIBREF3) and multi-document summarization (e.g.,BIBREF4, BIBREF3, BIBREF5).\nText summarization is broadly classified into two categories: extractive (e.g., BIBREF3 and BIBREF6) and abstractive summarization (e.g., BIBREF7, BIBREF8 and BIBREF9). Extractive approaches select sentences from a given document and groups them to form concise summaries. By contrast, abstractive approaches generate human-readable summaries that primarily capture the semantics of input documents and contain rephrased key content. The former task falls under the classification paradigm, and the latter belongs to the generative modeling paradigm, and therefore, it is a much harder problem to solve. The backbone of state-of-the-art summarization models is a typical encoder-decoder BIBREF10 architecture that has proved to be effective for various sequential modeling tasks such as machine translation, sentiment analysis, and natural language generation. It contains an encoder that maps the raw input word vector representations to a latent vector. Then, the decoder usually equipped with a variant of the attention mechanism BIBREF11 uses the latent vectors to generate the output sequence, which is the summary in our case. These models are trained in a supervised learning setting where we minimize the cross-entropy loss between the predicted and the target summary. Encoder-decoder models have proved effective for short sequence tasks such as machine translation where the length of a sequence is less than 120 tokens. However, in text summarization, the length of the sequences vary from 400 to 800 tokens, and modeling long-term dependencies becomes increasingly difficult.\nDespite the metric's known drawbacks, text summarization models are evaluated using ROUGE BIBREF12, a discrete similarity score between predicted and target summaries based on 1-gram, 2-gram, and n-gram overlap. Cross-entropy loss would be a convenient objective on which to train the model since ROUGE is not differentiable, but doing so would create a mismatch between metrics used for training and evaluation. Though a particular summary scores well on ROUGE evaluation comparable to the target summary, it will be assigned lower probability by a supervised model. To tackle this problem, we have used a self-critic policy gradient method BIBREF13 to train the models directly using the ROUGE score as a reward. In this paper, we propose an architecture that addresses the issues discussed above.\nTo tackle this problem, we have used a self-critic policy gradient method (Rennie et al., 2016) to train the models directly using the ROUGE score as a reward.",

However, we argue that rather than treating user utterances and agents responses in an isolated manner, there is merit in jointly clustering them. There is adjacency information of these utterances that can be utilized to identify better user intents and system responses. As an example, consider agent utterances A.2 in box A and A.2 in box C in Figure FIGREF5 (a). The utterances “Which operating system do you use?\" and “What OS is installed in your machine\" have no syntactic similarity and therefore may not be grouped together. However the fact that these utterances are adjacent to the similar user utterances “I am unable to start notes email client\" and “Unable to start my email client\" provides some evidence that the agent utterances might be similar. Similarly the user utterances “My system keeps getting rebooted\" and “Machine is booting time and again\" ( box B and D in Figure FIGREF5 (a))- that are syntactically not similar - could be grouped together since the adjacent agent utterances, “Is your machine heating up?\" and “Is the machine heating?\" are similar.\nSimilarly the agents utterances can be clustered to identify system responses.

        "question": "Are the schemes proposed by them the first research on transfer learning for RNN based language models with privacy preserving?",
        "answer": "Yes.",
        "evidence": "Recently there has been a considerable interest in language modeling due to various academic and commercial demands. Academically, many studies have investigated this domain such as machine translation, chat-bot, message generation, image tagging and other language-related areas. Commercially, it can be used as a core technology for providing a new application on consumer products or services. For instance, an automatic message-reply prediction service can be launched in mobile devices, thus helping a user to send a reply message when he/she is not provided with a proper input interface.\nTo model the language of human dialogue, a recurrent neural network (RNN) structure is known to show the state of the arts performance with its ability to learn a sequential pattern of the data BIBREF0 . Among the RNN structures, a Long Short-Term Memory RNN (LSTM-RNN) and its variants are successfully used for language modeling tasks BIBREF1 , BIBREF2 . However, as a kind of deep learning technique, the LSTM-RNN and the RNN structure requires both a large number of data and huge computing power to train the model properly. Hence any attempts for applying the RNN structure to personalized language modeling are mainly constrained by the following two limitations. First, personal mobile devices contain private message data among close acquaintances, so users seldom agree to transfer their log out of the devices. This causes a limitation of gathering the whole user data to common computing spaces, where high-performance machines are available. Second, in relatively small computing machines, i.e., smart phone, it is not always-guaranteed to have enough resources to train a deep model within the devices.\nTo resolve these limitations, we propose fast transfer learning schemes. It trains a base model with a large dataset and copies its first n-many layers to the first n-many layers of a target model. Then the target model is fine-tuned with relatively small target data. Several learning schemes such as freezing a certain layer or adding a surplus layer are proposed for achieving the result. In experiments, we trained a general language model with huge corpus such as an Workshop on Statistical Machine Translation (WMT) data and a movie script data by using powerful computing machines, and then transferred the model to target environment for updating to be a personalized language model. With this approach, the final model can mimic target user's language style with proper syntax.\nIn the experiments, we trained the general language model with literary-style data and applied the transfer learning with spoken-style data. Then we evaluated the model output for sentence completion task in a qualitative and a quantitative manner. The test result showed that the model learned the style of the target language properly. Another test was conducted by training the general language model with the script of the drama, “Friends,\" and by applying transfer learning with main character corpora from the script to generate the personalized language model. The message-reply prediction task was evaluated with this model. The test result shows higher similarity between the output of the personalized language model and the same user dialogue than the one between the output of the personalized language model and other users' dialogues.\nThe contributions of this paper are as follows. First, we propose efficient transfer learning schemes for personalized language modeling, which is the first research on transfer learning for RNN based language models with privacy preserving. Second, we show the applicability of our research to the target scenario in the short message reply application by training the model in the similar environment to that of the mobile device, and highlight its test results.\nFirst, we propose efficient transfer learning schemes for personalized language modeling, which is the first research on transfer learning for RNN based language models with privacy preserving.",

        "evidence": "",
        "answer": "We can prescribe an exercise program through the lens of FITT: frequency, intensity, time, and type. For frequency, we should aim for 3-5 days per week, with the higher the better the improvements for C-R fitness. As for intensity, we want to aim for 60-90% HRR (heart rate recovery), anywhere from 4-8 RPE (rate of perceived exertion). Since Roslyn is 36 years of age, her predicted maximum heart rate is 184bpm, and we are given that her RHR (resting heart rate) is 64bpm. Thus, we’re aiming for a target heart rate range of 136 BPM to 172 BPM. For time, the duration depends on intensity, but optimally, we want to be working out for at least 20 minutes and at most an hour. As for the type of exercise, we can assess the options that are available and feasible for Roslyn to perform, and choose between weight-bearing exercises (such as walking or jogging) and non-weight-bearing exercises such as swimming or rowing. Another thing to consider is that Roslyn is sedentary, and may need to slowly progress into a more intense workout. A sample exercise training program for Roslyn may first start with a moderate-intensity aerobic activity for 30 minutes a day, three times a week (Monday, Wednesday, and Friday). As she gets more acclimated to the exercise level, we want to progress to more vigorous exercise. According to David P. Swain, vigorous aerobic exercise may result in “substantially more benefits than moderate-intensity exercise”, which include but are not limited to greater improvements in aerobic fitness and greater reductions in coronary heart disease risk. Thus, we can add two more days of vigorous aerobic exercise for Roslyn, such as jogging for 20 minutes on Tuesdays and Thursdays. Another important aspect to consider is motivation, which we can help Roslyn maintain by switching up her forms of exercise to keep interest.

        "evidence": "Datasets and Models We evaluate our adversarial attacks on different text classification datasets from tasks such as sentiment classification, subjectivity detection and question type classification. Amazon, Yelp, IMDB are sentence-level sentiment classification datasets which have been used in recent work BIBREF15 while MR BIBREF16 contains movie reviews based on sentiment polarity. MPQA BIBREF17 is a dataset for opinion polarity detection, Subj BIBREF18 for classifying a sentence as subjective or objective and TREC BIBREF19 is a dataset for question type classification.\nWe use 3 popular text classification models: word-LSTM BIBREF20, word-CNN BIBREF21 and a fine-tuned BERT BIBREF12 base-uncased classifier. For each dataset we train the model on the training data and perform the adversarial attack on the test data. For complete model details refer to Appendix.\nAs a baseline, we consider TextFooler BIBREF11 which performs synonym replacement using a fixed word embedding space BIBREF22. We only consider the top $K{=}50$ synonyms from the MLM predictions and set a threshold of 0.8 for the cosine similarity between USE based embeddings of the adversarial and input text.\nResults We perform the 4 modes of our attack and summarize the results in Table . Across datasets and models, our BAE attacks are almost always more effective than the baseline attack, achieving significant drops of 40-80% in test accuracies, with higher average semantic similarities as shown in parentheses. BAE-R+I is the strongest attack since it allows both replacement and insertion at the same token position, with just one exception. We observe a general trend that the BAE-R and BAE-I attacks often perform comparably, while the BAE-R/I and BAE-R+I attacks are much stronger. We observe that the BERT-based classifier is more robust to the BAE and TextFooler attacks than the word-LSTM and word-CNN models which can be attributed to its large size and pre-training on a large corpus.\nThe baseline attack is often stronger than the BAE-R and BAE-I attacks for the BERT based classifier. We attribute this to the shared parameter space between the BERT-MLM and the BERT classifier before fine-tuning. The predicted tokens from BERT-MLM may not drastically change the internal representations learned by the BERT classifier, hindering their ability to adversarially affect the classifier prediction.\nEffectiveness We study the effectiveness of BAE on limiting the number of R/I operations permitted on the original text. We plot the attack performance as a function of maximum $\\%$ perturbation (ratio of number of word replacements and insertions to the length of the original text) for the TREC dataset. From Figure , we clearly observe that the BAE attacks are consistently stronger than TextFooler. The classifier models are relatively robust to perturbations up to 20$\\%$, while the effectiveness saturates at 40-50$\\%$. Surprisingly, a 50$\\%$ perturbation for the TREC dataset translates to replacing or inserting just 3-4 words, due to the short text lengths.\nQualitative Examples We present adversarial examples generated by the attacks on a sentence from the IMDB and Yelp datasets in Table . BAE produces more natural looking examples than TextFooler as tokens predicted by the BERT-MLM fit well in the sentence context. TextFooler tends to replace words with complex synonyms, which can be easily detected. Moreover, BAE's additional degree of freedom to insert tokens allows for a successful attack with fewer perturbations.\nHuman Evaluation We consider successful adversarial examples generated from the Amazon and IMDB datasets and verify their sentiment and grammatical correctness. Human evaluators annotated the sentiment and the grammar (Likert scale of 1-5) of randomly shuffled adversarial examples and original texts. From Table , BAE and TextFooler have inferior accuracies compared to the Original, showing they are not always perfect. However, BAE has much better grammar scores, suggesting more natural looking adversarial examples.\nAblation Study We analyze the benefits of R/I operations in BAE in Table . From the table, the splits $\\mathbb {A}$ and $\\mathbb {B}$ are the $\\%$ of test points which compulsorily need I and R operations respectively for a successful attack. We can observe that the split $\\mathbb {A}$ is larger than $\\mathbb {B}$ thereby indicating the importance of the I operation over R. Test points in split require both R and I operations for a successful attack. Interestingly, split is largest for Subj, which is the most robust to attack (Table ) and hence needs both R/I operations. Thus, this study gives positive insights towards the importance of having the flexibility to both replace and insert words.\nRefer to the Appendix for additional results, effectiveness graphs and details of human evaluation.\nWe use 3 popular text classification models: word-LSTM (Hochreiter and Schmidhuber, 1997), word-CNN (Kim, 2014) and a fine-tuned BERT (Devlin et al., 2018) base-uncased classifier.",

        "evidence": "Datasets. We perform our experiments with two predetermined event categories: cyber security (CyberAttack) and death of politicians (PoliticianDeath). These event categories are chosen as they are representative of important event types that are of interest to many governments and companies. The need to create our own dataset was motivated by the lack of public datasets for event detection on microposts. The few available datasets do not suit our requirements. For example, the publicly available Events-2012 Twitter dataset BIBREF20 contains generic event descriptions such as Politics, Sports, Culture etc. Our work targets more specific event categories BIBREF21. Following previous studies BIBREF1, we collect event-related microposts from Twitter using 11 and 8 seed events (see Section SECREF2) for CyberAttack and PoliticianDeath, respectively. Unlabeled microposts are collected by using the keyword `hack' for CyberAttack, while for PoliticianDeath, we use a set of keywords related to `politician' and `death' (such as `bureaucrat', `dead' etc.) For each dataset, we randomly select 500 tweets from the unlabeled subset and manually label them for evaluation. Table TABREF25 shows key statistics from our two datasets.\nComparison Methods. To demonstrate the generality of our approach on different event detection models, we consider Logistic Regression (LR) BIBREF1 and Multilayer Perceptron (MLP) BIBREF2 as the target models. As the goal of our experiments is to demonstrate the effectiveness of our approach as a new model training technique, we use these widely used models. Also, we note that in our case other neural network models with more complex network architectures for event detection, such as the bi-directional LSTM BIBREF17, turn out to be less effective than a simple feedforward network. For both LR and MLP, we evaluate our proposed human-AI loop approach for keyword discovery and expectation estimation by comparing against the weakly supervised learning method proposed by BIBREF1 (BIBREF1) and BIBREF17 (BIBREF17) where only one initial keyword is used with an expectation estimated by an individual expert.\nParameter Settings. We empirically set optimal parameters based on a held-out validation set that contains 20% of the test data. These include the hyperparamters of the target model, those of our proposed probabilistic model, and the parameters used for training the target model. We explore MLP with 1, 2 and 3 hidden layers and apply a grid search in 32, 64, 128, 256, 512 for the dimension of the embeddings and that of the hidden layers. For the coefficient of expectation regularization, we follow BIBREF6 (BIBREF6) and set it to $\\lambda =10 \\times $ #labeled examples. For model training, we use the Adam BIBREF22 optimization algorithm for both models.\nEvaluation. Following BIBREF1 (BIBREF1) and BIBREF3 (BIBREF3), we use accuracy and area under the precision-recall curve (AUC) metrics to measure the performance of our proposed approach. We note that due to the imbalance in our datasets (20% positive microposts in CyberAttack and 27% in PoliticianDeath), accuracy is dominated by negative examples; AUC, in comparison, better characterizes the discriminative power of the model.\nCrowdsourcing. We chose Level 3 workers on the Figure-Eight crowdsourcing platform for our experiments. The inter-annotator agreement in micropost classification is taken into account through the EM algorithm. For keyword discovery, we filter keywords based on the frequency of the keyword being selected by the crowd. In terms of cost-effectiveness, our approach is motivated from the fact that crowdsourced data annotation can be expensive, and is thus designed with minimal crowd involvement. For each iteration, we selected 50 tweets for keyword discovery and 50 tweets for micropost classification per keyword. For a dataset with 80k tweets (e.g., CyberAttack), our approach only requires to manually inspect 800 tweets (for 8 keywords), which is only 1% of the entire dataset.\nFollowing Ritter et al. (2015) and Konovalov et al. (2017), we use accuracy and area under the precisionrecall curve (AUC) metrics to measure the performance of our proposed approach.",

        "answer": "Both random forest and deep learning classifiers.",
        "evidence": "We pose the prediction task as a binary classification problem. Specifically, given an image and associated question, a system outputs a binary label indicating whether a crowd will agree on the same answer. Our goal is to design a system that can detect which visual questions to assign a disagreement label, regardless of the disagreement cause (e.g., subjectivity, ambiguity, difficulty). We implement both random forest and deep learning classifiers.\nA visual question is assigned either an answer agreement or disagreement label. To assign labels, we employ 10 crowdsourced answers for each visual question. A visual question is assigned an answer agreement label when there is an exact string match for 9 of the 10 crowdsourced answers (after answer pre-preprocessing, as discussed in the previous section) and an answer disagreement label otherwise. Our rationale is to permit the possibility of up to one “careless/spam\" answer per visual question. The outcome of our labeling scheme is that a disagreement label is agnostic to the specific cause of disagreement and rather represents the many causes (described above).\nFor our first system, we use domain knowledge to guide the learning process. We compile a set of features that we hypothesize inform whether a crowd will arrive at an undisputed, single answer. Then we apply a machine learning tool to reveal the significance of each feature. We propose features based on the observation that answer agreement often arises when 1) a lay person's attention can be easily concentrated to a single, undisputed region in an image and 2) a lay person would find the requested task easy to address.\nWe employ five image-based features coming from the salient object subitizing BIBREF22 (SOS) method, which produces five probabilities that indicate whether an image contains 0, 1, 2, 3, or 4+ salient objects. Intuitively, the number of salient objects shows how many regions in an image are competing for an observer's attention, and so may correlate with the ease in identifying a region of interest. Moreover, we hypothesize this feature will capture our observation from the previous study that counting problems typically leads to disagreement for images showing many objects, and agreement otherwise.\nWe employ a 2,492-dimensional feature vector to represent the question-based features. One feature is the number of words in the question. Intuitively, a longer question offers more information and we hypothesize additional information makes a question more precise. The remaining features come from two one-hot vectors describing each of the first two words in the question. Each one-hot vector is created using the learned vocabularies that define all possible words at the first and second word location of a question respectively (using training data, as described in the next section). Intuitively, early words in a question inform the type of answers that might be possible and, in turn, possible reasons/frequency for answer disagreement. For example, we expect “why is\" to regularly elicit many opinions and so disagreement. This intuition about the beginning words of a question is also supported by our analysis in the previous section which shows that different answer types yield different biases of eliciting answer agreement versus disagreement.\nWe leverage a random forest classification model BIBREF23 to predict an answer (dis)agreement label for a given visual question. This model consists of an ensemble of decision tree classifiers. We train the system to learn the unique weighted combinations of the aforementioned 2,497 features that each decision tree applies to make a prediction. At test time, given a novel visual question, the trained system converts a 2,497 feature descriptor of the visual question into a final prediction that reflects the majority vote prediction from the ensemble of decision trees. The system returns the final prediction along with a probability indicating the system's confidence in that prediction. We employ the Matlab implementation of random forests, using 25 trees and the default parameters.\nWe next adapt a VQA deep learning architecture BIBREF24 to learn the predictive combination of visual and textual features. The question is encoded with a 1024-dimensional LSTM model that takes in a one-hot descriptor of each word in the question. The image is described with the 4096-dimensional output from the last fully connected layer of the Convolutional Neural Network (CNN), VGG16 BIBREF25 . The system performs an element-wise multiplication of the image and question features, after linearly transforming the image descriptor to 1024 dimensions. The final layer of the architecture is a softmax layer.\nWe train the system to predict (dis)agreement labels with training examples, where each example includes an image and question. At test time, given a novel visual question, the system outputs an unnormalized log probability indicating its belief in both the agreement and disagreement label. For our system's prediction, we convert the belief in the disagreement label into a normalized probability. Consequently, predicted values range from 0 to 1 with lower values reflecting greater likelihood for crowd agreement.\nWe pose the prediction task as a binary classification problem. Specifically, given an image and associated question, a system outputs a binary label indicating whether a crowd will agree on the same answer. Our goal is to design a system that can detect which visual questions to assign a disagreement label, regardless of the disagreement cause (e.g., subjectivity, ambiguity, difficulty).

        "evidence": "The pre-trained language model, BERT BIBREF0 has led to a big breakthrough in various kinds of natural language understanding tasks. Ideally, people can start from a pre-trained BERT checkpoint and fine-tune it on a specific downstream task. However, the original BERT models are memory-exhaustive and latency-prohibitive to be served in embedded devices or CPU-based online environments. As the memory and latency constraints vary in different scenarios, the pre-trained BERT model should be adaptive to different requirements with accuracy retained to the largest extent. Existing BERT-oriented model compression solutions largely depend on knowledge distillation BIBREF1, which is inefficient and resource-consuming because a large training corpus is required to learn the behaviors of a teacher. For example, DistilBERT BIBREF2 is re-trained on the same corpus as pre-training a vanilla BERT from scratch; and TinyBERT BIBREF3 utilizes expensive data augmentation to fit the distillation target. The costs of these model compression methods are as large as pre-training and unaffordable for low-resource settings. Therefore, it is straight-forward to ask, can we design a lightweight method to generate adaptive models with comparable accuracy using significantly less time and resource consumption? In this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions. Specifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation. Initially, the architecture and weights of student model are inherited from the BERT teacher. In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation. Because weight pruning and matrix factorization help to generate better initial and intermediate status\nin the knowledge distillation iterations, the accuracy and efficiency of model compression can be greatly improved.\nWe conduct extensive experiments on five public datasets of natural language understanding. As an example, the performance comparison of LadaBERT and state-of-the-art models on MNLI-m dataset is illustrated in Figure FIGREF1. We can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios. Especially, LadaBERT-1 outperforms BERT-PKD significantly under $2.5\\times $ compression ratio, and LadaBERT-3 outperforms TinyBERT under $7.5\\times $ compression ratio while the training speed is accelerated by an order of magnitude.\nThe rest of this paper is organized as follows. First, we summarizes the related works of model compression and their applications to BERT in Section SECREF2. Then, the methodology of LadaBERT is introduced in Section SECREF3, and experimental results are presented in Section SECREF4. At last, we conclude this work and discuss future works in Section SECREF5.\nInitially, the architecture and weights of student model are inherited from the BERT teacher.",

Many, including triathlon historian and author Scott Tinley, consider events in early twentieth century France to be the beginnings of triathlon, with many three element multisport events of differing composition appearing, all called by different names. The earliest record for an event was from 1901 in Joinville-le-Pont, Val-de-Marne: it called itself \"Les Trois Sports\" (The Three Sports). It was advertised as an event for \"the sportsmen of the time\" and consisted of a run, a bicycle and a canoe segment. By 19 June 1921, the event in Joinville-le-Pont had become more like a standard triathlon, with the canoe segment being replaced with a swim. According to the newspaper L’Auto, the race consisted of a 3 km (1.9 mi) run, a 12 km (7.5 mi) bike ride and the crossing of the river Marne, all staged consecutively and without a break. Throughout the 1920s other bike, run, and swim events appeared in different cities, such as the “Course des Trois Sports” in Marseille and \"La Course des Débrouillards\" in Poissy. These multisport events would continue to slowly spread and grow in popularity: by 1934 \"Les Trois Sports\" was being hosted in the city of La Rochelle, though it consisted of three distinct events, swimming a 200 m (660 ft) channel crossing, a 10 km (6 mi) bike competition around the harbour of La Rochelle and the parc Laleu, and a 1.2 km (0.75 mi) run in the stadium André-Barbeau.

Over this dataset, we compare the methodology suggested here to those reported by BIBREF1, BIBREF4.

As positive examples we take, from this list, all concepts which appear more than 50 times in Wikipedia. This leaves 608 controversial Wikipedia concepts. For negative examples, we follow BIBREF1, BIBREF4 and select a like number of concepts at random. Here too, since each concept only has a binary label, we convert our estimation into a binary classification, and report accuracy.\nDataset III is extracted from 3561 concepts whose Wikipedia pages are under edit protection, assuming that many of them are likely to be controversial.

Importantly, in each sentence we mask the words that reference the concept – i.e., the surface form of the hyperlink leading to the concept – by a fixed, singular token, thus focusing solely on the context within which the concepts are mentioned.\nWe consider three datasets, two of which are a contribution of this work.",

        "question": "Based on the reference text, provide a summary of how the monthly benefit amount for social security is calculated.",
        "evidence": "Primary Insurance Amount and Monthly Benefit Amount calculations\nMain article: Primary Insurance Amount\nWorkers in Social Security covered employment pay FICA (Federal Insurance Contributions Act) or SECA (Self Employed Contributions Act) taxes and earn quarters of coverage if earnings are above minimum amounts specified in the law. Workers with 40 quarters of coverage (QC) are \"fully insured\" and eligible for retirement benefits. Retirement benefit amounts depend upon the average of the person's highest 35 years of \"adjusted\" or \"indexed\" earnings. A person's payroll-taxable earnings from earlier years are adjusted for economy-wide wage growth, using the national average wage index (AWI), and then averaged. If the worker has fewer than 35 years of covered earnings these non-contributory years are assigned zero earnings. The sum of the highest 35 years of adjusted or indexed earnings divided by 420 (35 years times 12 months per year) produces a person's Average Indexed Monthly Earnings or AIME.\n\nThe AIME is then used to calculate the Primary Insurance Amount or PIA. For workers who turn 62 in 2021, the PIA computation formula is:\n\n(a) 90 percent of the first $996 of average indexed monthly earnings, plus\n\n(b) 32 percent of average indexed monthly earnings between $996 and $6,002, plus\n\n(c) 15 percent of average indexed monthly earnings over $6,002\n\nFor workers who turn 62 in the future, the 90, 32, and 15 percent factors in the computation formula will remain the same but the dollar amounts in the formula (called bend points) will increase by wage growth in the national economy, as measured by the AWI. Because the AIME and the PIA calculation incorporate the AWI, Social Security benefits are said to be wage indexed. Because wages typically grow faster than prices, the PIAs for workers turning 62 in the future will tend to be higher in real terms but similar relative to average earnings in the economy at the time age 62 is attained.\n\nMonthly benefit amounts are based on the PIA. Once the PIA is computed, it is indexed for price inflation over time. Thus, Social Security monthly benefit amounts retain their purchasing power throughout a person's retirement years.\n\nA worker who first starts receiving a retirement benefit at the full retirement age receives a monthly benefit amount equal to 100 percent of the PIA. A worker who claims the retirement benefit before the full retirement age receives a reduced monthly benefit amount and a worker who claims at an age after the full retirement age (up to age 70) receives an increased monthly amount.\n\nThe 90, 32, and 15 percent factors in the PIA computation lead to higher replacement rates for persons with lower career earnings. For example, a retired individual whose average earnings are below the first bend point can receive a monthly benefit at the full retirement age that equals 90 percent of the person's average monthly earnings before retirement. The table shows replacement rates for workers who turned 62 in 2013.\n\nThe PIA computation formula for disabled workers parallels that for retired workers except the AIME is based on fewer years to reflect disablement before age 62. The monthly benefit amount of a disabled worker is 100 percent of PIA.\n\nBenefits for spouses, children, and widow(er)s depend on the PIAs of a spouse or a deceased spouse. Aged spouse and divorced spouse beneficiaries can receive up to 50 percent of the PIA. Survivor benefit rates are higher and aged widow(er)s and aged surviving divorced spouses can receive 100 percent of the PIA.\n\nFederal, state and local employees who have elected (when they could) NOT to pay FICA taxes are eligible for a reduced FICA benefits and full Medicare coverage if they have more than forty quarters of qualifying Social Security covered work. To minimize the Social Security payments to those who have not contributed to FICA for 35+ years and are eligible for federal, state and local benefits, which are usually more generous, Congress passed the Windfall Elimination Provision, WEP. The WEP provision will not eliminate all Social Security or Medicare eligibility if the worker has 40 quarters of qualifying income, but calculates the benefit payments by reducing the 90% multiplier in the first PIA bendpoint to 40–85% depending on the number of Years of Coverage. Foreign pensions are subject to WEP.\n\nA special minimum benefit, based on an alternative PIA calculation, is available for some workers with long careers but low earnings. However, it is rarely higher than the regularly-computed PIA and thus few workers qualify for the special minimum benefit. Only 32,000 individuals received the special minimum benefit in 2019.\n\nThe benefits someone is eligible for are potentially so complicated that potential retirees should consult the Social Security Administration directly for advice. Many questions are addressed and at least partially answered on many online publications and online calculators.",

We join all arguments in the extracted n-ary relation into a sequence as our to the point context. Figure FIGREF5 shows n-ary relations extracted from OpenIE. As we can see, OpenIE extracts multiple relations for complex sentences. Here we select the most informative relation according to three criteria in the order of descending importance: (1) having the maximal number of overlapped tokens between the answer and the relation; (2) being assigned the highest confidence score by OpenIE; (3) containing maximum non-stop words. As shown in Figure FIGREF5, our criteria can select answer-relevant relations (waved in Figure FIGREF5), which is especially useful for sentences with extraneous information. In rare cases, OpenIE cannot extract any relation, we treat the sentence itself as the to the point context.\nTable TABREF8 shows some statistics to verify the intuition that the extracted relations can serve as more to the point context. We find that the tokens in relations are 61% more likely to be used in the target question than the tokens in sentences, and thus they are more to the point.

        "evidence": "State-of-the-art (SOTA) artificial neural networks (ANNs) achieve impressive results in a variety of machine intelligence tasks. However, they largely rely on mechanisms that diverge from the original inspiration from biological neural networks. As a result, only a small part of this prolific field also contributes to computational neuroscience. In fact, this biological implausibility is also an important issue for machine intelligence. For their impressive performance, ANNs trade off other desired properties, which are present in biological systems. For example, ANN training often demands very large and labelled datasets. When labels are unavailable, self-supervised learning schemes exist, where supervisory error signals generated by the network itself are exploited and backpropagated from the output towards the input to update the network's parameters. However, this global propagation of signals in deep networks introduces another limitation. Namely, it prevents the implementation of efficient distributed computing hardware that would be based on only local signals from neighbouring physical nodes in the network, and is in contrast to local synaptic plasticity rules that partly govern biological learning. Several pieces of work have been addressing parts of the biological implausibility and hardware-inefficiency of backpropagation in ANNs. such as the need for exactly symmetric forward and backward weights or the waiting time caused by the network's forward-backward pass between two training updates in a layer (weight transport and update-locking problems). Recently, an approximation to backpropagation that is mostly Hebbian, i.e. relies on mostly pre-and post-synaptic activity of each synapse, has been achieved by reducing the global error requirements to 1-bit information. Two schemes that further localize the signal that is required for a weight update are Equilibrium Propagation and Predictive Coding. Both methods approximate backpropagation through Hebbian-like learning, by delegating the global aspect of the computation, from a global error signal, to a global convergence of the network state to an equilibrium. This equilibrium is reached through several iterative steps of feed-forward and feed-back communication throughout the network, before the ultimate weight update by one training example. The biological plausibility and hardware-efficiency of this added iterative process of signal propagation are open questions that begin to be addressed.\nMoreover, learning through backpropagation, and presumably also its approximations, has another indication of biological implausibility, which also significantly limits ANN applicability. Namely, it produces networks that are confused by small adversarial perturbations of the input, which are imperceptible by humans. It has recently been proposed that a defence strategy of \"deflection\" of adversarial attacks may be the ultimate solution to that problem. Through this strategy, to cause confusion in the network's inferred class, the adversary is forced to generate such a changed input that really belongs to the distribution of a different input class. Intuitively, but also strictly by definition, this deflection is achieved if a human assigns to the perturbed input the same label that the network does. Deflection of adversarial attacks in ANNs has been demonstrated by an elaborate scheme that is based on detecting the attacks. However, the human ability to deflect adversarial perturbations likely does not rely on detecting them, but rather on effectively ignoring them, making the deflecting type of robustness an emergent property of biological computation rather than a defence mechanism. The biological principles that underlie this property of robustness are unclear, but it might emerge from the distinct algorithms that govern learning in the brain.\nTherefore, what is missing is a biologically plausible model that can learn from fewer data-points, without labels, through local plasticity, and without feedback from distant layers. This model could then be tested for emergent adversarial robustness. A good candidate category of biological networks and learning algorithms is that of competitive learning. Neurons that compete for their activation through lateral inhibition are a common connectivity pattern in the superficial layers of the cerebral cortex). This pattern is described as winner-take-all (WTA), because competition suppresses activity of weakly activated neurons, and emphasizes strong ones. Combined with Hebbian-like plasticity rules, WTA connectivity gives rise to competitivelearning algorithms. These networks and learning schemes have been long studied (Von der and a large literature based on simulations and analyses describes their functional properties. A WTA neuronal layer, depending on its specifics, can restore missing input signals, perform decision making i.e. winner selection, and generate oscillations such as those that underlie brain rhythms. Perhaps more importantly, its neurons can learn to become selective to different input patterns, such as orientation of visual bars in models of the primary visual cortex (Von der, MNIST handwritten digits, CIFAR10 objects, spatiotemporal spiking patterns, and can adapt dynamically to model changing objects. The WTA model is indeed biologically plausible, Hebbian plasticity is local, and learning is input-driven, relying on only feed-forward communication of neurons -properties that seem to address several of the limitations of ANNs. However, the model's applicability is limited to simple tasks. That is partly because the related theoretical literature remains surprisingly unsettled, despite its long history, and the strong and productive community interest. described a very related theory but for a model that is largely incompatible with ANNs and thus less practical. It uses spiking and stochastic neurons, input has to be discretized, and each input feature must be encoded through multiple binary neurons. Moreover, it was only proven for neurons with an exponential activation function. It remains therefore unclear which specific plasticity rule and structure could optimize an ANN WTA for Bayesian inference. It is also unclear how to minimize a common loss function such as cross-entropy despite unsupervised learning, and how a WTA could represent varying families of probability distributions. In summary, on the theoretical side, an algorithm that is simultaneously normative, based on WTA networks and Hebbian unsupervised plasticity, performs Bayesian inference, and, importantly, is composed of conventional, i.e. non-spiking, ANN elements and is rigorously linked to modern ANN tools such as cross-entropy loss, would be an important advance but has been missing. On the practical side, evidence that Hebbian WTA networks could be useful for presently pertinent issues of modern ANNs such as adversarial robustness, generation of synthetic images, or faster learning, has remained limited. Here we aim to fill these gaps. Recently, when WTA networks were studied in a theoretical framework compatible with conventional machine learning (ML), but in the context of short-term as opposed to long-term Hebbian plasticity, it resulted in surprising practical advantages over supervised ANNs. A similar theoretical approach could also reveal unknown advantages of long-term Hebbian plasticity in WTA networks. In addition, it could provide insights into how a WTA microcircuit could participate in larger-scale computation by deeper cortical or artificial networks.\nHere we construct \"SoftHebb\", a biologically plausible WTA model that is based on standard ratebased neurons as in ANNs, can accommodate various activation functions, and learns without labels, using local plasticity and only feed-forward communication, i.e. the properties we seek in an ANN. Importantly, it is equipped with a simple normalization of the layer's activations, and an optional temperature-scaling mechanism, producing a soft WTA instead of selecting a single \"hard\" winner neuron. This allows us to prove formally that a SoftHebb layer is a generative mixture model that objectively minimizes its Kullback-Leibler (KL) divergence from the input distribution through Bayesian inference, thus providing a new formal ML-theoretic perspective of these networks. We complement our main results, which are theoretical, with experiments that are small-scale but produce intriguing results. As a generative model, SoftHebb has a broader scope than classification, but we test it on image classification tasks. Surprisingly, in addition to overcoming several inefficiencies of backpropagation, the unsupervised WTA model also outperforms a supervised two-layer perceptron in several aspects: learning speed and accuracy in the first presentation of the training dataset, robustness to noisy data and to one of the strongest white-box adversarial attacks, i.e. projected gradient descent (PGD), and without any explicit defence. Interestingly, the SoftHebb model also exhibits inherent properties of deflection of the adversarial attacks, and generates object interpolations.\nHere we construct \"SoftHebb\", a biologically plausible WTA model that is based on standard ratebased neurons as in ANNs, can accommodate various activation functions, and learns without labels, using local plasticity and only feed-forward communication, i.e. the properties we seek in an ANN.****Some of our main contributions are theoretical and their proof is fully reproducible by following the rigorous derivations in the main text and in the appendices.",

        "evidence": "Text simplification aims to reduce the lexical and structural complexity of a text, while still retaining the semantic meaning, which can help children, non-native speakers, and people with cognitive disabilities, to understand text better. One of the methods of automatic text simplification can be generally divided into three categories: lexical simplification (LS) BIBREF0 , BIBREF1 , rule-based BIBREF2 , and machine translation (MT) BIBREF3 , BIBREF4 . LS is mainly used to simplify text by substituting infrequent and difficult words with frequent and easier words. However, there are several challenges for the LS approach: a great number of transformation rules are required for reasonable coverage and should be applied based on the specific context; third, the syntax and semantic meaning of the sentence is hard to retain. Rule-based approaches use hand-crafted rules for lexical and syntactic simplification, for example, substituting difficult words in a predefined vocabulary. However, such approaches need a lot of human-involvement to manually define these rules, and it is impossible to give all possible simplification rules. MT-based approach has attracted great attention in the last several years, which addresses text simplification as a monolingual machine translation problem translating from 'ordinary' and 'simplified' sentences.\nIn recent years, neural Machine Translation (NMT) is a newly-proposed deep learning approach and achieves very impressive results BIBREF5 , BIBREF6 , BIBREF7 . Unlike the traditional phrased-based machine translation system which operates on small components separately, NMT system is being trained end-to-end, without the need to have external decoders, language models or phrase tables. Therefore, the existing architectures in NMT are used for text simplification BIBREF8 , BIBREF4 . However, most recent work using NMT is limited to the training data that are scarce and expensive to build. Language models trained on simplified corpora have played a central role in statistical text simplification BIBREF9 , BIBREF10 . One main reason is the amount of available simplified corpora typically far exceeds the amount of parallel data. The performance of models can be typically improved when trained on more data. Therefore, we expect simplified corpora to be especially helpful for NMT models.\nIn contrast to previous work, which uses the existing NMT models, we explore strategy to include simplified training corpora in the training process without changing the neural network architecture. We first propose to pair simplified training sentences with synthetic ordinary sentences during training, and treat this synthetic data as additional training data. We obtain synthetic ordinary sentences through back-translation, i.e. an automatic translation of the simplified sentence into the ordinary sentence BIBREF11 . Then, we mix the synthetic data into the original (simplified-ordinary) data to train NMT model. Experimental results on two publicly available datasets show that we can improve the text simplification quality of NMT models by mixing simplified sentences into the training set over NMT model only using the original training data.\nHowever, there are several challenges for the LS approach: a great number of transformation rules are required for reasonable coverage and should be applied based on the specific context; third, the syntax and semantic meaning of the sentence is hard to retain.",

The improvement could be justified just by the larger vocabulary in Twi, but in the case of Yorùbá the enhancement is there with almost half of the vocabulary size. We found out that adding some noisy texts (C2 dataset) slightly improves the correlation for Twi language but not for the Yorùbá language. The Twi language benefits from Wikipedia articles because its inclusion doubles the vocabulary and reduces the bias of the model towards religious texts. However, for Yorùbá, noisy texts often ignore diacritics or tonal marks which increases the vocabulary size at the cost of an increment in the ambiguity too. As a result, the correlation is slightly hurt. One would expect that training with more data would improve the quality of the embeddings, but we found out with the results obtained with the C3 dataset, that only high-quality data helps. The addition of JW300 boosts the vocabulary in both cases, but whereas for Twi the corpus mixes dialects and is noisy, for Yorùbá it is very clean and with full diacritics.

He just didn't know. Was it that he felt that he was not worthy? Hardly. He was a kind and respectful person, and, he had to admit, a fine hunter. So what was wrong with him? He decided to speak to the Koradji, the wise man. Surely he would know. The Koradji was peering into his fire, deep in thought, when the young man approached, but somehow knew of his presence. \"You are troubled,\" he asked and continued to gaze into the fire. \"I seek vour wisdom, Uncle,\" he replied, his voice hardly more than a whisper. \"Wisdom comes at a price\" said the Koradji, without raising his head. \"But I have nothing to offer,\" the young man told him. \"I think you have,\" said the Koradji.\" then added: \"But that can wait. Now sit and tell me what is troubling vou.\" The young man sat opposite the old man and told him everything. When he had finished, the Koradji nodded his head thoughtfully, then gazed into the young man's eyes.\n\"Now listen carefully and heed my words,\" he said. Then he continued. \"This land is to you as it is to all living things.\nTherefore, we have the right to breathe its air, drink its water and nourish our bodies with its bounty. We have no need to stand apart from others because we have much to contribute, and how much we contribute is in accordance with our own measure.\" There was a pause while he added wood to the fire. Then he continued. \"Now hear these words and keep them in your mind. No one has the right to tell another that they may not do these things, because each of us are children of Mother Earth. Of course,\" he added quickly, \"there will be those who stand above others, and those who are stronger, or of a different tribe, but it matters not, because we each have an equal right to our place in the sun, to live in accordance with our conscience.\" He waved a mosquito from his arm and smiled. \"And, yes, even a mosquito\". There was a long silence after the Koradji had finished speaking, then the young man spoke finally. \"I have listened to your words Uncle, and they are very wise,\" he said, \"but how can I pay you?\"",

In tennis, players also hit the ball back and forth but they hit it to each other over a net. In tennis, the ball has a fuzzy outer layer which causes the ball's trajectory to be more influenced by the spin on the ball. The rackets in tennis are larger and have higher tension.\n\nA tennis court is much larger than a racquetball court measuring 78 ft long and 36 ft wide.

        "evidence": "Past research took a reductionist approach, separately considering these two problems of “what” and “how” via content selection and question construction. Given a sentence or a paragraph as input, content selection selects a particular salient topic worthwhile to ask about and determines the question type (What, When, Who, etc.). Approaches either take a syntactic BIBREF11 , BIBREF12 , BIBREF13 or semantic BIBREF14 , BIBREF3 , BIBREF15 , BIBREF16 tack, both starting by applying syntactic or semantic parsing, respectively, to obtain intermediate symbolic representations. Question construction then converts intermediate representations to a natural language question, taking either a tranformation- or template-based approach. The former BIBREF17 , BIBREF18 , BIBREF13 rearranges the surface form of the input sentence to produce the question; the latter BIBREF19 , BIBREF20 , BIBREF21 generates questions from pre-defined question templates. Unfortunately, such QG architectures are limiting, as their representation is confined to the variety of intermediate representations, transformation rules or templates.\nIn contrast, neural models motivate an end-to-end architectures. Deep learned frameworks contrast with the reductionist approach, admitting approaches that jointly optimize for both the “what” and “how” in an unified framework. The majority of current NQG models follow the sequence-to-sequence (Seq2Seq) framework that use a unified representation and joint learning of content selection (via the encoder) and question construction (via the decoder). In this framework, traditional parsing-based content selection has been replaced by more flexible approaches such as attention BIBREF22 and copying mechanism BIBREF23 . Question construction has become completely data-driven, requiring far less labor compared to transformation rules, enabling better language flexibility compared to question templates.\nPast research took a reductionist approach, separately considering these two problems of “what” and “how” via content selection and question construction. \nIn contrast, neural models motivate an end-to-end architectures.

Used since 1969, it has become a well-recognized and often imitated part of American jargon. In 2012, Advertising Age called \"Virginia is for Lovers\" \"one of the most iconic ad campaigns in the past 50 years.\"\n\nHistory\nA team led by David N. Martin and George Woltz of Martin and Woltz Inc. of Richmond, Virginia created the slogan after winning the Virginia State Travel account in 1968. Originally, they had come up with history ads, \"Virginia is for History Lovers\"; beach ads, \"Virginia is for Beach Lovers\"; and mountain ads, \"Virginia is for Mountain Lovers\". This approach was eventually discarded as too limiting, and the qualifiers were dropped. Martin and Woltz Inc. eventually gained prominence and grew to become The Martin Agency. The Martin Agency says that, contrary to some claims, the slogan is not a reference to the United States Supreme Court's 1967 ruling in Loving v. Virginia, which legalized interracial marriage in the United States.\n\nIn 1969, the Virginia State Travel Service (now the Virginia Tourism Corporation) adopted the \"Virginia is for Lovers\" slogan and the first ad campaign using the tagline appeared in March 1969, in an issue of Modern Bride.\n\nIn 2009, \"Virginia is for Lovers\" was inducted into the Madison Avenue Advertising Walk of Fame, a creation of Advertising Week, the largest collection of advertising, marketing and media professionals in North America. These inductees were also included in the Advertising Icon Museum. Also in 2009, \"Virginia is for Lovers\" was acknowledged as one of the top ten tourism marketing campaigns of all time by Forbes.com. In 2016, the Virginia Tourism Corporation began selling apparel with a rainbow-colored heart in the logo as part of an LGBT tourism promotion campaign. The slogan began appearing on the state's license plates in 2014 and the state's welcome signs in 2015.\n\nIn popular culture\nThe slogan has been mentioned by a variety of artists over the years. In 2005, post-hardcore band Hawthorne Heights alluded to the phrase in the title of their single “Ohio Is for Lovers,” which would become widely regarded as an anthem of the early 2000’s emo music scene. American Idol winner Jordin Sparks recorded a song called \"Virginia is for Lovers\" in 2007, which was featured as a bonus track on her self-titled debut album. The slogan is mentioned in The Hold Steady song \"Killer Parties\", and Willie Adler, guitarist for Lamb of God, has the slogan printed on the neck of his custom guitars. The slogan is also mentioned in the Kenny Chesney song \"Get Along\". Virginia Beach-based rap group Clipse include the slogan in their song \"Virginia,\" from their 2002 album Lord Willin', proclaiming: \"Virginia's for lovers, but trust there's hate here / For out-of-towners, who think they're gon' move weight here.\"",

Falak-numa means \"Like the Sky\" or \"Mirror of Sky\" in Urdu.\n\nDesign\nAn English architect William Ward Marret designed the palace. Sir Vicar's monogram \"VO\" is on the furniture, walls and ceiling of the palace. It is made completely with Italian marble with stained-glass windows and covers an area of 93,970 square metres (1,011,500 sq ft).\n\nThe palace was built in the shape of a scorpion with two stings spread out as wings in the north. The middle part is occupied by the main building and the kitchen, Gol Bangla, Zenana Mehal, and harem quarters stretch to the south. The Nawab was an avid traveller, and his influences show in the architecture, which combines Italian and Tudor influences.\n\nHistory\n\nFalaknuma Palace, photographed by Lala Deen Dayal in 1900.\nSir Viqar-ul-Umra, the Prime Minister of Hyderabad, after a visit to Europe, decided to build a European styled residence for himself. The foundation stone for the construction was laid by Sir Vicar on 3 March 1884. It took nine years to complete the construction and furnish the palace. Sir Vicar moved into the Gol Bangla and Zanana Mahel of the Falaknuma Palace in December 1890 and closely monitored the finishing work at the Mardana portion.\n\nHe used the palace as his private residence until the palace was handed over to the 6th Nizam of Hyderabad around 1897–1898.\n\nThe palace was built and furnished at a cost of ₹4 million (equivalent to ₹1.6 billion or US$20 million in 2020), which necessitated borrowing money from the Bank of Bengal. In the spring of 1897, the sixth Nizam of Hyderabad, Mir Mahbub Ali Khan was invited to stay at the palace. He extended his stay to a week, then a fortnight, and then a month, which prompted Sir Viqar to offer it to him. The Nizam accepted but paid some of the value of the palace; the Paigah family maintains that around ₹2 million (equivalent to ₹510 million or US$6.4 million in 2020) was paid.\n\nThe Nizam used the palace as a guest house for the royal guests visiting the kingdom of Hyderabad. The list of royal visitors included King George V, Queen Mary, Edward VIII and Tsar Nicholas II. The palace fell into disuse after the 1950s. The last important guest was the President of India, Rajendra Prasad, in 1951.\n\nThe palace was then restored after being leased by the Taj Group of Hotels. The restoration, which began in 2000, took ten years, and was managed by Princess Esra, the first wife of Mukarram Jah. Now, the hotel is again used to host guests in Hyderabad, such as Aga Khan IV, Ivanka Trump and Narendra Modi.",

Despite the large diversity of the collected responses for intervention, we find workers tend to have certain strategies for intervention.\n\nIdentify Hate Keywords: One of the most common strategies is to identify the inappropriate terms in the post and then urge the user to stop using that work. For example, “The C word and language attacking gender is unacceptable. Please refrain from future use.” This strategy is often used when the hatred in the post is mainly conveyed by specific hate keywords.\n\nCategorize Hate Speech: This is another common strategy used by the workers. The workers classify hate speech into different categories, such as racist, sexist, homophobic, etc. This strategy is often combined with identifying hate keywords or targets of hatred. For example, “The term \"\"fa**ot\"\" comprises homophobic hate, and as such is not permitted here.”\n\nPositive Tone Followed by Transitions: This is a strategy where the response consists of two parts combined with a transitional word, such as “but” and “even though”. The first part starts with affirmative terms, such as “I understand”, “You have the right to”, and “You are free to express”, showing kindness and understanding, while the second part is to alert the users that their post is inappropriate. For example, “I understand your frustration, but the term you have used is offensive towards the disabled community. Please be more aware of your words.”. Intuitively, compared with the response that directly warns, this strategy is likely more acceptable for the users and be more likely to clam down a quarrel full of hate speech.\n\nSuggest Proper Actions: Besides warning and discouraging the users from continuing hate speech, workers also suggest the actions that the user should take. This strategy can either be combined with other strategies mentioned above or be used alone. In the latter case, a negative tone can be greatly alleviated. For example, “I think that you should do more research on how resources are allocated in this country.”\nRemoving duplicates, there are 21,747 unique intervention responses in the aggregated Gab dataset and 7,641 in the aggregated Reddit dataset.

        "evidence": "It is well known that language has certain structural properties which allows natural language speakers to make “infinite use of finite means\" BIBREF3 . This structure allows us to generalize beyond the typical machine learning definition of generalization BIBREF4 (which considers performance on the distribution that generated the training set), permitting the understanding of any utterance sharing the same structure, regardless of probability. For example, sentences of length 100 typically do not appear in natural text or speech (our personal 'training set'), but can be understood regardless due to their structure. We refer to this notion as linguistic generalization .\nMany problems in NLP are treated as sequence to sequence tasks with solutions built on seq2seq-attention based models. While these models perform very well on standard datasets and also appear to capture some linguistic structure BIBREF5 , BIBREF6 , BIBREF7 , they also can be quite brittle, typically breaking on uncharacteristic inputs BIBREF8 , BIBREF1 , indicating that the extent of linguistic generalization these models achieve is still somewhat lacking.\nDue to the high capacity of these models, it is not unreasonable to expect them to learn some structure from the data. However, learning structure is not a sufficient condition to achieving linguistic generalization. If this structure is to be usable on data outside the training distribution, the model must learn the structure without additionally learning (overfitting on) patterns specific to the training data. One may hope, given the right hyperparameter configuration and regularization, that a model converges to a solution that captures the reusable structure without overfitting too much on the training set. While this solution exists in theory, in practice, it may be difficult to find.\nIn this work, we look at the feasibility of training and tuning seq2seq-attention models towards a solution that generalizes in this linguistic sense. In particular, we train models on a symbol replacement task with a well defined generalizable structure. The task is simple enough that all models achieve near perfect accuracy on the standard test set, i.e., where the inputs are drawn from the same distribution as that of the training set. We then test these models for linguistic generalization by creating test sets of uncharacteristic inputs, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned. Our results indicate that generalization is highly sensitive; such that even changes in the random seed can drastically affect the ability to generalize. This dependence on an element that is not (or ideally should not be) a hyperparameter suggests that the line between generalization and failure is quite fine, and may not be feasible to reach simply by hyperparameter tuning alone.\nThe task is simple enough that all models achieve near perfect accuracy on the standard test set, i.e., where the inputs are drawn from the same distribution as that of the training set.",

One of the most important aspects of human behavior is emotion. If machines could detect human emotional expressions, it could be used to improve on verity of applications such as marketing BIBREF0 , human-computer interactions BIBREF1 , political science BIBREF2 etc.\nEmotion in humans is complex and hard to distinguish. There have been many emotional models in psychology which tried to classify and point out basic human emotions such as Ekman's 6 basic emotions BIBREF3 , Plutchik's wheel of emotions BIBREF4 , or Parrott's three-level categorization of emotions BIBREF5 . These varieties show that emotions are hard to define, distinguish, and categorize even for human experts.\nBy adding the complexity of language and the fact that emotion expressions are very complex and context dependant BIBREF6 , BIBREF7 , BIBREF8 , we can see why detecting emotions in textual data is a challenging task. This difficulty can be seen when human annotators try to assign emotional labels to the text, but using various techniques the annotation task can be accomplished with desirable agreement among the annotators BIBREF9 .\nIn this work, we argue that creating a model that can better capture the context and sequential nature of text , can significantly improve the performance in the hard task of emotion detection.

At the heart of the Transformer lie multi-head attention mechanisms: each word is represented by multiple different weighted averages of its relevant context. As suggested by recent works on interpreting attention head roles, separate attention heads may learn to look for various relationships between tokens BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9.\nThe attention distribution of each head is predicted typically using the softmax normalizing transform. As a result, all context words have non-zero attention weight. Recent work on single attention architectures suggest that using sparse normalizing transforms in attention mechanisms such as sparsemax – which can yield exactly zero probabilities for irrelevant words – may improve performance and interpretability BIBREF12, BIBREF13, BIBREF14. Qualitative analysis of attention heads BIBREF0 suggests that, depending on what phenomena they capture, heads tend to favor flatter or more peaked distributions.\nRecent works have proposed sparse Transformers BIBREF10 and adaptive span Transformers BIBREF11. However, the “sparsity\" of those models only limits the attention to a contiguous span of past tokens, while in this work we propose a highly adaptive Transformer model that is capable of attending to a sparse set of words that are not necessarily contiguous. Figure FIGREF1 shows the relationship of these methods with ours.\nOur contributions are the following:\nWe introduce sparse attention into the Transformer architecture, showing that it eases interpretability and leads to slight accuracy gains.\nWe propose an adaptive version of sparse attention, where the shape of each attention head is learnable and can vary continuously and dynamically between the dense limit case of softmax and the sparse, piecewise-linear sparsemax case.\nWe make an extensive analysis of the added interpretability of these models, identifying both crisper examples of attention head behavior observed in previous work, as well as novel behaviors unraveled thanks to the sparsity and adaptivity of our proposed model.\nWe introduce sparse attention into the Transformer architecture, showing that it eases interpretability and leads to slight accuracy gains.",

BIBREF1 picard1997affective provides a detailed discussion of the importance of affect analysis in human communication and interaction. Within this context the analysis of human affect from text is an important topic in natural language understanding, examples of which include sentiment analysis from Twitter BIBREF2 , affect analysis from poetry BIBREF3 and studies of correlation between function words and social/psychological processes BIBREF4 . People exchange verbal messages which not only contain syntactic information, but also information conveying their mental and emotional states. Examples include the use of emotionally colored words (such as furious and joy) and swear words. The automated processing of affect in human verbal communication is of great importance to understanding spoken language systems, particularly for emerging applications such as dialogue systems and conversational agents.\nStatistical language modeling is an integral component of speech recognition systems, with other applications such as machine translation and information retrieval. There has been a resurgence of research effort in recurrent neural networks for language modeling BIBREF5 , which have yielded performances far superior to baseline language models based on n-gram approaches. However, there has not been much effort in building neural language models of text that leverage affective information. Current literature on deep learning for language understanding focuses mainly on representations based on word semantics BIBREF6 , encoder-decoder models for sentence representations BIBREF7 , language modeling integrated with symbolic knowledge BIBREF8 and neural caption generation BIBREF9 , but to the best of our knowledge there has been no work on augmenting neural language modeling with affective information, or on data-driven approaches to generate emotional text.\nMotivated by these advances in neural language modeling and affective analysis of text, in this paper we propose a model for representation and generation of emotional text, which we call the Affect-LM. Our model is trained on conversational speech corpora, common in language modeling for speech recognition applications BIBREF10 . Figure 1 provides an overview of our Affect-LM and its ability to generate emotionally colored conversational text in a number of affect categories with varying affect strengths. While these parameters can be manually tuned to generate conversational text, the affect category can also be automatically inferred from preceding context words. Specifically for model training, the affect category is derived from features generated using keyword spotting from a dictionary of emotional words, such as the LIWC (Linguistic Inquiry and Word Count) tool BIBREF11 . Our primary research questions in this paper are:\nQ1:Can Affect-LM be used to generate affective sentences for a target emotion with varying degrees of affect strength through a customizable model parameter?\nQ2:Are these generated sentences rated as emotionally expressive as well as grammatically correct in an extensive crowd-sourced perception experiment?\nQ3:Does the automatic inference of affect category from the context words improve language modeling performance of the proposed Affect-LM over the baseline as measured by perplexity?\nThe remainder of this paper is organized as follows. In Section \"Related Work\" , we discuss prior work in the fields of neural language modeling, and generation of affective conversational text. In Section \"LSTM Language Model\" we describe the baseline LSTM model and our proposed Affect-LM model. Section \"Experimental Setup\" details the experimental setup, and in Section \"Results\" , we discuss results for customizable emotional text generation, perception studies for each affect category, and perplexity improvements over the baseline model before concluding the paper in Section \"Conclusions and Future Work\" .\nAffect is a term that subsumes emotion and longer term constructs such as mood and personality and refers to the experience of feeling or emotion.",

        "question": "Why is it so hard now to name a favorite musician?",
        "evidence": "",
        "answer": "Compared to 10 years ago, this question has grown a lot harder to answer. In the old days, songs were indexed by song-writers. Prior to the digital age, the most popular media was physical cassettes, and it’s natural to group the cassettes by artists. Moreover, artists used to be the primary mechanism to discover new music. The cost of listening to new songs was usually high, since there were few ways to try new music, so fans tended to buy music from the same artists for quality (and taste) assurance.\n\nWith the evolution of music streaming and the decline of the recording industry, the granularity of “listening to music” has refined significantly. Listeners no longer need to buy whole cassettes, but can pick songs individually. Moreover, recommendation algorithms allow fans to discover music by popularity, genre or even mood.  As a result, music fans now sample from such a wide range of artists that it’s hard to name a single favorite. And due to the insane number of accessible songs, Even if you listen to a specific artist most frequently among your collection, you may still only like a small percentage of all the songs he/she wrote, which leads to the shaky conviction that you actually have a “favorite musician”.\n\nOn the other hand, I believe the palette for music depends a lot on “environment”. It could be a physical environment (eg. beach or gym), an action (eg. working or cooking), or a mood (eg. chill or psyched). The like or dislike towards a certain piece of music changes drastically when these variables change. To some extent, I view music more as a tool than as an art form, in that I seek certain utility from music at different times. However, music judgment for me is also not 100% a rational or utilitarian process. It still very much comes from intuition, though that intuition is heavily biased by environmental factors.",

The characteristic rings that appear in its slices resemble tree rings, and give the cake its German name, Baumkuchen, which literally translates to \"tree cake\" or \"log cake\".\n\nHistory\nIt is disputed who made the first Baumkuchen and where it was first baked. One theory is that it was invented in the German town of Salzwedel, which is further popularized by the town itself. Another theory suggests it began as a Hungarian wedding cake.[citation needed] In Ein new Kochbuch (lit. \"A New Cookbook\"), the first cookbook written for professional chefs by Marx Rumpolt, there is a recipe for Baumkuchen. This publication puts the origin of Baumkuchen as far back at 1581, the year the cookbook was first published. Marx Rumpolt had previously worked as a chef in Hungary and Bohemia.[citation needed]\n\nCharacteristics\n\nBaumkuchen baked on a spit\nTraditionally, Baumkuchen is made on a spit by brushing on even layers of batter and then rotating the spit around a heat source. Each layer is allowed to brown before a new layer of batter is poured. When the cake is removed and sliced, each layer is divided from the next by a golden line, resembling the growth rings on a crosscut tree. A typical Baumkuchen is made up of 15 to 20 layers of batter. However, the layering process for making Baumkuchen can continue until the cakes are quite large. Skilled pastry chefs have been known to create cakes with 25 layers and weighing over 100 pounds (45 kg). When cooked on a spit, it is not uncommon for a finished Baumkuchen to be 3–4 feet (0.91–1.22 m) tall.\n\nBaumkuchen ingredients are typically butter, eggs, sugar, vanilla, salt, and flour. Baking powder is not considered a traditional ingredient. The ratio of flour, butter and eggs is typically 1:1:2 respectively (i.e., 100 grams of flour, 100 grams of butter and 200 grams of eggs). The recipe can be varied by adding other ingredients, such as ground nuts, honey, marzipan, nougat and rum or brandy, to the batter or filling. Additionally, Baumkuchen may be covered with sugar or chocolate glaze. With some recipes, the fully baked and cooled Baumkuchen is first coated with marmalade or jam, and then covered with chocolate.",

        "question": "What information is concurrently predicted in their method?",
        "answer": "User's, system's intents and semantic slots.",
        "evidence": "Considerable progress has been made building end-to-end dialog systems for collaborative tasks in which users cooperate with the system to achieve a common goal. Examples of collaborative tasks include making restaurant reservations and retrieving bus time-table information. Since users typically have clear and explicit intentions in collaborative tasks, existing systems commonly classify user utterances into pre-defined intents. In contrast, non-collaborative tasks are those where the users and the system do not strive to achieve the same goal. Examples of such tasks include deceiving attackers, persuading users to donate to a cause BIBREF1, and negotiating a product price BIBREF2, BIBREF3. In these tasks, users often perform complex actions that are beyond a simple set of pre-defined intents. In order to reach a common state, the user and the system need to build rapport and trust which naturally involves off-task content. Previous work did not model off-task content BIBREF2, which may have led to less optimal results. For example, in the persuasion task BIBREF1, users would ask the system “How do you feel about war?\" An example of an on-task system response that the system could have made is “Do you want to make a donation?\", which sticks to the task but neglects users' question. However, a better response to such an off-task question is “War is destructive and pitiless, but you can donate to help child victims of war.\" This response is better, as it has been found that users are more likely to end the conversation if the system neglects their questions BIBREF4. Therefore, we need to design a system that handles both on-task and off-task information appropriately and in a way that leads back to the system's goal.\nTo tackle the issue of incoherent system responses to off-task content, previous studies have built hybrid systems to interleave off-task and on-task content. BIBREF4 used a rule-based dialog manager for on-task content and a neural model for off-task content, and trained a reinforcement learning model to select between these two models based on the dialog context. However, such a method is difficult to train and struggles to generalize beyond the movie promotion task they considered. To tackle these problems, we propose a hierarchical intent annotation scheme that separates on-task and off-task information in order to provide detailed supervision. For on-task information, we directly use task-related intents for representation. Off-task information, on the other hand, is too general to categorize into specific intents, so we choose dialog acts that convey syntax information. These acts, such as “open question\" are general to all tasks.\nPrevious studies use template-based methods to maintain sentence coherence. However, rigid templates lead to limited diversity, causing the user losing engagement. On the other hand, language generation models can generate diverse responses but are bad at being coherent. We propose Multiple Intents and Semantic Slots Annotation Neural Network (MISSA) to combine the advantages of both template and generation models and takes advantage from the hierarchical annotation at the same time. MISSA follows the TransferTransfo framework BIBREF0 with three modifications: (i) We first concurrently predict user's, system's intents and semantic slots; (ii) We then perform conditional generation to improve generated response's coherence. Specifically, we generate responses conditioned on the above intermediate representation (intents and slots); (iii) Finally, we generate multiple responses with the nucleus sampling strategy BIBREF5 and then apply a response filter, which contains a set of pre-defined constraints to select coherent responses. The constraints in the filter can be defined according to specific task requirements or general conversational rules.\nTo enrich publicly available non-collaborative task datasets, we collect a new dataset AntiScam, where users defend themselves against attackers trying to collect personal information. As non-collaborative tasks are still relatively new to the study of dialog systems, there are insufficiently many meaningful datasets for evaluation and we hope this provides a valuable example. We evaluate MISSA on the newly collected AntiScam dataset and an existing PersuasionForGood dataset. Both automatic and human evaluations suggest that MISSA outperforms multiple competitive baselines.\nIn summary, our contributions include: (i) We design a hierarchical intent annotation scheme and a semantic slot annotation scheme to annotate the non-collaborative dialog dataset, we also propose a carefully-designed AntiScam dataset to facilitate the research of non-collaborative dialog systems. (ii) We propose a model that can be applied to all non-collaborative tasks, outperforming other baselines on two different non-collaborative tasks. (iii) We develop an anti-scam dialog system to occupy attacker's attention and elicit their private information for social good. Furthermore, we also build a persuasion dialog system to persuade people to donate to charities. We release the code and data.\n(i) We first concurrently predict user's, system's intents and semantic slots;",

Together, these plays make up Sophocles' three Theban plays. Oedipus represents two enduring themes of Greek myth and drama: the flawed nature of humanity and an individual's role in the course of destiny in a harsh universe.\n\nIn the best-known version of the myth, Oedipus was born to King Laius and Queen Jocasta of Thebes. Laius wished to thwart the prophecy, so he sent a shepherd-servant to leave Oedipus to die on a mountainside. However, the shepherd took pity on the baby and passed him to another shepherd who gave Oedipus to King Polybus and Queen Merope to raise as their own. Oedipus learned from the oracle at Delphi of the prophecy that he would end up killing his father and marrying his mother but, unaware of his true parentage, believed he was fated to murder Polybus and marry Merope, so left for Thebes. On his way, he met an older man and killed him in a quarrel. Continuing on to Thebes, he found that the king of the city (Laius) had recently been killed and that the city was at the mercy of the Sphinx. Oedipus answered the monster's riddle correctly, defeating it and winning the throne of the dead king – and the hand in marriage of the king's widow, who was also (unbeknownst to him) his mother Jocasta.\n\n\nDetail of ancient fresco in which Oedipus solves the riddle of the Sphinx. Egyptian Museum, 2nd c. CE\nYears later, to end a plague on Thebes, Oedipus searched to find who had killed Laius and discovered that he himself was responsible. Jocasta, upon realizing that she had married her own son, hanged herself. Oedipus then seized two pins from her dress and blinded himself with them.\n\nThe legend of Oedipus has been retold in many versions and was used by Sigmund Freud to name and give mythic precedent to the Oedipus complex.",

Vietnamese syllable is not fully meaningful. However, it is also explained in the meaning and structure characteristics. For example, the token “kỳ” in “quốc kỳ” whereas “quốc” means national, “kỳ” means flag. Therefore, “quốc kỳ” means national flag.\nConsider dictionary used for evaluating the corpus, extracting features for models, and evaluating the systems, there are many Vietnamese dictionaries, however we recommend the Vietnamese dictionary of Hoang Phe, so called Hoang Phe Dictionary.

For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. Interest in using hydrogen for on-board storage of energy in zero-emissions vehicles is motivating the development of new methods of storage, more adapted to this new application.

        "question": "What is applied to encounter class imbalance?",
        "answer": "Cost-sensitive SVM is applied to enconter class imbalance.",
        "evidence": "In this paper, we explore the feasibility of automatically recognising signals of cyberbullying. A crucial difference with state-of-the-art approaches to cyberbullying detection is that we aim to model bullying attacks, as well as reactions from victims and bystanders (i.e., all under one binary label `signals of cyberbullying'), since these could likewise indicate that cyberbullying is going on. The experiments described in this paper focus on the detection of such posts, which are signals of a potential cyberbullying event to be further investigated by human moderators.\nThe English and Dutch corpus contain 113,698 and 78,387 posts, respectively. As shown in Table TABREF36 , the experimental corpus features a heavily imbalanced class distribution with the large majority of posts not being part of cyberbullying. In classification, this class imbalance can lead to decreased performance. We apply cost-sensitive SVM as a possible hyperparameter in optimisation to counter this. The cost-sensitive SVM reweighs the penalty parameter INLINEFORM0 of the error term by the inverse class-ratio. This means that misclassifications of the minority positive class are penalised more than classification errors on the majority negative class. Other pre-processing methods to handle data imbalance in classification include feature filtering metrics and data resampling BIBREF56 . These methods were omitted as they were found to be too computationally expensive given our high-dimensional dataset.\nFor the automatic detection of cyberbullying, we performed binary classification experiments using a linear kernel support vector machine (SVM) implemented in LIBLINEAR BIBREF57 by making use of Scikit-learn BIBREF58 , a machine learning library for Python. The motivation behind this is twofold: i) support vector machines (SVMs) have proven to work well for tasks similar to the ones under investigation BIBREF38 and ii) LIBLINEAR allows fast training of large-scale data which allow for a linear mapping (which was confirmed after a series of preliminary experiments using LIBSVM with linear, RBF and polynomial kernels).\nThe classifier was optimised for feature type (cf. Section SECREF38 ) and hyperparameter combinations (cf. Table TABREF37 ). Model selection was done using 10-fold cross validation in grid search over all possible feature types (i.e., groups of similar features, like different orders of INLINEFORM0 -gram bag-of-words features) and hyperparameter configurations. The best performing hyperparameters are selected by F INLINEFORM1 -score on the positive class. The winning model is then retrained on all held-in data and subsequently tested on a hold-out test set to assess whether the classifier is over- or under-fitting. The holdout represents a random sample ( INLINEFORM2 ) of all data. The folds were randomly stratified splits over the hold-in class distribution. Testing all feature type combinations is a rudimentary form of feature selection and provides insight into which types of features work best for this particular task.\nFeature selection over all individual features was not performed because of the large feature space (NL: 795,072 and EN: 871,296 individual features). BIBREF59 , among other researchers, demonstrated the importance of joint optimisation, where feature selection and hyperparameter optimisation are performed simultaneously, since the techniques mutually influence each other.\nThe optimised models are evaluated against two baseline systems: i) an unoptimised linear-kernel SVM (configured with default parameter settings) based on word INLINEFORM0 -grams only and, ii) a keyword-based system that marks posts as positive for cyberbullying if they contain a word from existing vocabulary lists composed by aggressive language and profanity terms.\nWe apply cost-sensitive SVM as a possible hyperparameter in optimisation to counter this.",

        "evidence": "Language models can be optimized to recognize syntax and semantics with great accuracy BIBREF0. However, the output generated can be repetitive and generic leading to monotonous or uninteresting responses (e.g “I don't know”) regardless of the input BIBREF1. While application of attention BIBREF2, BIBREF3 and advanced decoding mechanisms like beam search and variation sampling BIBREF4 have shown improvements, it does not solve the underlying problem. In creative text generation, the objective is not strongly bound to the ground truth—instead the objective is to generate diverse, unique or original samples. We attempt to do this through a discriminator which can give feedback to the generative model through a cost function that encourages sampling of creative tokens. The contributions of this paper are in the usage of a GAN framework to generate creative pieces of writing. Our experiments suggest that generative text models, while very good at encapsulating semantic, syntactic and domain information, perform better with external feedback from a discriminator for fine-tuning objectiveless decoding tasks like that of creative text. We show this by evaluating our model on three very different creative datasets containing poetry, metaphors and lyrics.\nPrevious work on handling the shortcomings of MLE include length-normalizing sentence probability BIBREF5, future cost estimation BIBREF6, diversity-boosting objective function BIBREF7, BIBREF1 or penalizing repeating tokens BIBREF8. When it comes to poetry generation using generative text models, Zhang and Lapata BIBREF9, Yi et al. BIBREF10 and Wang et al. BIBREF11 use language modeling to generate Chinese poems. However, none of these methods provide feedback on the quality of the generated sample and hence, do not address the qualitative objective required for creative decoding. For the task of text generation, MaskGAN BIBREF12 uses a Reinforcement Learning signal from the discriminator, FMD-GAN BIBREF13 uses an optimal transport mechanism as an objective function. GumbelGAN BIBREF14 uses Gumbel-Softmax distribution that replaces the non-differentiable sample from a categorical distribution with a differentiable sample to propagate stronger gradients. Li et al. BIBREF1 use a discriminator for a diversity promoting objective. Yu et al. BIBREF15 use SeqGAN to generate poetry and comment on the performance of SeqGAN over MLE in human evaluations, encouraging our study of GANs for creative text generation. However, these studies do not focus solely on creative text.\nPrevious work on handling the shortcomings of MLE include length-normalizing sentence probability [6], future cost estimation [7], diversity-boosting objective function [8, 2] or penalizing repeating tokens [9].",

For this task, we evaluate all models on five benchmark datasets: First, we employ the noun-noun subset of bless, which contains hypernymy annotations for 200 concrete, mostly unambiguous nouns. Negative pairs contain a mixture of co-hyponymy, meronymy, and random pairs. This version contains 14,542 total pairs with 1,337 positive examples. Second, we evaluate on leds BIBREF13 , which consists of 2,770 noun pairs balanced between positive hypernymy examples, and randomly shuffled negative pairs. We also consider eval BIBREF14 , containing 7,378 pairs in a mixture of hypernymy, synonymy, antonymy, meronymy, and adjectival relations. eval is notable for its absence of random pairs. The largest dataset is shwartz BIBREF2 , which was collected from a mixture of WordNet, DBPedia, and other resources. We limit ourselves to a 52,578 pair subset excluding multiword expressions. Finally, we evaluate on wbless BIBREF15 , a 1,668 pair subset of bless, with negative pairs being selected from co-hyponymy, random, and hyponymy relations. Previous work has used different metrics for evaluating on BLESS BIBREF11 , BIBREF5 , BIBREF6 . We chose to evaluate the global ranking using Average Precision. This allowed us to use the same metric on all detection benchmarks, and is consistent with evaluations in BIBREF4 .\nDirection: In direction prediction, the task is to identify which term is broader in a given pair of words. For this task, we evaluate all models on three datasets described by BIBREF16 : On bless, the task is to predict the direction for all 1337 positive pairs in the dataset. Pairs are only counted correct if the hypernymy direction scores higher than the reverse direction, i.e. INLINEFORM0 . We reserve 10% of the data for validation, and test on the remaining 90%.

Since this task requires three-way classification (hypernymy, hyponymy, and other), we perform two-stage classification. First, a threshold is tuned using 2% of the data, identifying whether a pair exhibits hypernymy in either direction. Second, the relative comparison of scores determines which direction is predicted. As with wbless, we report the average accuracy over 1000 iterations.\nGraded Entailment: In graded entailment, the task is to quantify the degree to which a hypernymy relation holds.

RBMs have found applications in dimensionality reduction, classification, collaborative filtering, feature learning, topic modelling and even many body quantum mechanics. They can be trained in either supervised or unsupervised ways, depending on the task.\n\nAs their name implies, RBMs are a variant of Boltzmann machines, with the restriction that their neurons must form a bipartite graph: a pair of nodes from each of the two groups of units (commonly referred to as the \"visible\" and \"hidden\" units respectively) may have a symmetric connection between them; and there are no connections between nodes within a group. By contrast, \"unrestricted\" Boltzmann machines may have connections between hidden units. This restriction allows for more efficient training algorithms than are available for the general class of Boltzmann machines, in particular the gradient-based contrastive divergence algorithm.\n\nRestricted Boltzmann machines can also be used in deep learning networks.

Briefly, we adaptively adjust hyperparameters for firefly over the course of online optimization, which gives us a favorable balance between time and compute requirements for running firefly against the simulator and tuning hyperparameters.

Therefore, we adopted a dynamic hyperparameter tuning strategy. Our implementation of the firefly optimizer tunes hyperparameters by scoring a set of hyperparameters based on its best performance over a sliding window of T data points. This allows us to adapt to the best hyperparameters on the fly, within the course of optimization, effectively balancing the number of runs that need to be run in the simulator and hyperparameter tuning. This dynamic hyperparameter tuning strategy requires some initial coverage of the hyperparameter space before hyperparameter tuning begins, and therefore, this tuning begins only after 750 datapoints.

        "question": "Given these paragraphs about Large language models, what is hallucination?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem.",

I was in DC that week for a work trip, and had extended my stay the weekend before and after, so we could spend time together. We'd only met a month prior, and after more than four weeks of long-distance text message exchanges,  it was exciting to finally be together in person. Our first date had been the weekend before, when we'd gone to a Jimmy Buffett concert. It was a magical night.\nIt was now 10am on the Saturday after the work week, and we were ready for another adventure.  Natalie, being from DC, wanted to show me the Dumbarton Oaks Gardens, so off we went.  Unfortunately, when we got there, the front gates were closed.  Still feeling adventurous, we decided to walk around the property, convinced we'd find an unlocked gate, door, or other way to get in.  Towards the back end of the property, while we didn't find an open gate, we did find one that was scale-able.  And that's exactly what we did.  We climbed over that fence, and welcomed ourselves to the beautiful gardens.  It was early august, and so much was still in bloom.  The gardens were empty,  and we thought we had the whole place to ourselves.  But, we soon found that that wasn't the case.  While exploring a small cottage that also seemed to double as an art gallery, we noticed a small pool right next to it.  We also noticed someone swimming in that pool. Presumably that person noticed us too, because a few minutes later a security guard came walking up to us while we were inspecting some fine smelling roses nearby.  It was too late to run away, so instead we walked up to the security guard, and thanked him for finding us.  As they escorted us out, we complimented them on the great state of the garden, though that didn't seem to calm him down much.  He was far too frustrated with the situation.  As they were about to lead us out through the front gate, we offered to pay for our admission.  They rather sternly refused, and insisted we leave immediately, which we did.  \nAnd that's how Natalie and I got our free tour of the gardens, and took one step closer to falling in love.

        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nWe experimented with two standard hashing algorithms, namely random hyperplane projection (Charikar, 2002) and iterative quantization (Gong and Lazebnik, 2011).",

Such distant supervision setting inevitably introduces noise in the learning process BIBREF3 and the resulting systems tend to lack explainability.\nWe argue that in order to study propaganda in a sound and reliable way, we need to rely on high-quality trusted professional annotations and it is best to do so at the fragment level, targeting specific techniques rather than using a label for an entire document or an entire news outlet.

        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching.

        "evidence": "Cyberbullying has been defined by the National Crime Prevention Council as the use of the Internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person. Various studies have estimated that between to 10% to 40% of internet users are victims of cyberbullying BIBREF0 . Effects of cyberbullying can range from temporary anxiety to suicide BIBREF1 . Many high profile incidents have emphasized the prevalence of cyberbullying on social media. Most recently in October 2017, a Swedish model Arvida Byström was cyberbullied to the extent of receiving rape threats after she appeared in an advertisement with hairy legs.\nDetection of cyberbullying in social media is a challenging task. Definition of what constitutes cyberbullying is quite subjective. For example, frequent use of swear words might be considered as bullying by the general population. However, for teen oriented social media platforms such as Formspring, this does not necessarily mean bullying (Table TABREF9 ). Across multiple SMPs, cyberbullies attack victims on different topics such as race, religion, and gender. Depending on the topic of cyberbullying, vocabulary and perceived meaning of words vary significantly across SMPs. For example, in our experiments we found that for word `fat', the most similar words as per Twitter dataset are `female' and `woman' (Table TABREF23 ). However, other two datasets do not show such particular bias against women. This platform specific semantic similarity between words is a key aspect of cyberbullying detection across SMPs. Style of communication varies significantly across SMPs. For example, Twitter posts are short and lack anonymity. Whereas posts on Q&A oriented SMPs are long and have option of anonymity (Table TABREF7 ). Fast evolving words and hashtags in social media make it difficult to detect cyberbullying using swear word list based simple filtering approaches. The option of anonymity in certain social networks also makes it harder to identify cyberbullying as profile and history of the bully might not be available.\nPast works on cyberbullying detection have at least one of the following three bottlenecks. First (Bottleneck B1), they target only one particular social media platform. How these methods perform across other SMPs is unknown. Second (Bottleneck B2), they address only one topic of cyberbullying such as racism, and sexism. Depending on the topic, vocabulary and nature of cyberbullying changes. These models are not flexible in accommodating changes in the definition of cyberbullying. Third (Bottleneck B3), they rely on carefully handcrafted features such as swear word list and POS tagging. However, these handcrafted features are not robust against variations in writing style. In contrast to existing bottlenecks, this work targets three different types of social networks (Formspring: a Q&A forum, Twitter: microblogging, and Wikipedia: collaborative knowledge repository) for three topics of cyberbullying (personal attack, racism, and sexism) without doing any explicit feature engineering by developing deep learning based models along with transfer learning.\nWe experimented with diverse traditional machine learning models (logistic regression, support vector machine, random forest, naive Bayes) and deep neural network models (CNN, LSTM, BLSTM, BLSTM with Attention) using variety of representation methods for words (bag of character n-gram, bag of word unigram, GloVe embeddings, SSWE embeddings). Summary of our findings and research contributions is as follows.\n– This the first work that systematically analyzes cyberbullying on various topics across multiple SMPs and applies transfer learning for cyberbullying detection task. – Presence of swear words is neither necessary nor sufficient for cyberbullying.Robust models for cyberbullying detection should not rely on such handcrafted features. – Deep Learning based models outperform traditional Machine Learning models for cyberbullying detection task. – Training datasets for cyberbullying detection contain only a few posts marked as a bullying.

An adversary for this classifier is a function $A$ which maps a sentence $s$ to its perturbed versions $\\lbrace s^{\\prime }_1, s^{\\prime }_2, \\ldots , s^{\\prime }_{n}\\rbrace $ such that each $s^{\\prime }_i$ is close to $s$ under some notion of distance between sentences. We define the robustness of classifier $C$ to the adversary $A$ as: \n$$R_{C,A} = \\mathbb {E}_s \\left[\\min _{s^{\\prime } \\in A(s)} \\mathbb {1}[C(s^{\\prime }) = y]\\right],$$   (Eq. 14) \nwhere $y$ represents the ground truth label for $s$ . In practice, a real-world adversary may only be able to query the classifier a few times, hence $R_{C,A}$ represents the worst-case adversarial performance of $C$ . Methods for generating adversarial examples, such as HotFlip BIBREF8 , focus on efficient algorithms for searching the $\\min $ above. Improving $R_{C,A}$ would imply better robustness against all these methods.\nWe explore adversaries which perturb sentences with four types of character-level edits:\n(1) Swap: swapping two adjacent internal characters of a word. (2) Drop: removing an internal character of a word. (3) Keyboard: substituting an internal character with adjacent characters of QWERTY keyboard (4) Add: inserting a new character internally in a word. In line with the psycholinguistic studies BIBREF5 , BIBREF4 , to ensure that the perturbations do not affect human ability to comprehend the sentence, we only allow the adversary to edit the internal characters of a word, and not edit stopwords or words shorter than 4 characters.\nFor 1-character attacks, we try all possible perturbations listed above until we find an adversary that flips the model prediction. For 2-character attacks, we greedily fix the edit which had the least confidence among 1-character attacks, and then try all the allowed perturbations on the remaining words. Higher order attacks can be performed in a similar manner. The greedy strategy reduces the computation required to obtain higher order attacks, but also means that the robustness score is an upper bound on the true robustness of the classifier.\nFor the ScRNN model, we use a single-layer BiLSTM with a hidden dimension size of 50.",

        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nKnowledge graphs enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants.",

A stray mongrel from the streets of Moscow, she flew aboard the Sputnik 2 spacecraft, launched into low orbit on 3 November 1957.

While this optimization can be done using any RL algorithm, including on-policy methods, we will focus on an off-policy actor-critic method.\nWe define the Q function as sum of augmented rewards under the learned dynamics model:\nWe approximate the Q function using a neural network Q ψ (s t , a t ) with parameters φ. We train the Q function using the TD loss on transitions sampled from the learned dynamics model:\nwhere • sg is the stop-gradient operator and\n) . The augmented reward, r, is estimated using the learned classifier. To estimate the corresponding value function, we use a 1-sample approximation:\nThe policy is trained to maximize the expected future (augmented) return, as estimated by the Q function:\nIn our implementation, we regularize the policy by adding an additional entropy regularizer. Following prior work, we maintain two Q functions and two target Q functions, use the minimum of the two target Q functions to compute the TD target. See Appendix C for details.\nUpdating the classifier. We train the classifier to distinguish real versus model transitions using the standard cross entropy loss: between training the policy on experience from the learned dynamics model with augmented rewards and updating the model+classifier using a GAN-like loss. Updates are gradient steps with the Adam optimizer.\n1: while not converged do 2:\nSample experience from learned model and modify rewards using the classifier (Eq. 5).\nUpdate policy and Q function using the model experience and augmented rewards (Eq.s 8 and 7). 4:\nUpdate model and classifier using GAN-like losses (Eq.s 9 and 10). 5:\n(Infrequently) Sample experience from real model. 6: return policy π θ (at | st).\nUpdating the dynamics model. To optimize the dynamics model, we rewrite the lower bound in terms of a single transition (derivation in Appendix A.6):\nThe approximation above reflects approximation error in learning the optimal classifier. This approximation is standard in prior work on GANs and adversarial inference. The procedure for optimizing the dynamics model and the classifier resembles a GAN: the classifier is optimized to distinguish real transitions from model transitions, and the model is updated to fool the classifier (and increase rewards). However, our method is not equivalent to simply replacing a maximum likelihood model with a GAN model. Indeed, such an approach would not optimize a lower bound on expected return. Rather, our model objective includes an additional value term and our policy objective includes an additional classifier term. These changes enable the model and policy to optimize the same objective, which is a lower bound on expected return.\nAlgorithm summary. We summarize the method in Alg. 1 and provide an illustration in Fig.. Implementing MnM on top of a standard model-based RL algorithm is straightforward. First, create an additional classifier network. Second, instead of using the maximum likelihood objective to train the model, use the GAN-like objective in Eq. 10 to update both the model and the classifier.

        "evidence": "The resource is comprised of 142 hours of spoken Mapudungun that was recorded during the AVENUE project BIBREF6 in 2001 to 2005. The data was recorded under a partnership between the AVENUE project, funded by the US National Science Foundation at Carnegie Mellon University, the Chilean Ministry of Education (Mineduc), and the Instituto de Estudios Indígenas at Universidad de La Frontera, originally spanning 170 hours of audio. We have recently cleaned the data and are releasing it publicly for the first time (although it has been shared with individual researchers in the past) along with NLP baselines.\nThe recordings were transcribed and translated into Spanish at the Instituto de Estudios Indígenas at Universidad de La Frontera. The corpus covers three dialects of Mapudungun: about 110 hours of Nguluche, 20 hours of Lafkenche and 10 hours of Pewenche. The three dialects are quite similar, with some minor semantic and phonetic differences. The fourth traditionally distinguished dialect, Huilliche, has several grammatical differences from the other three and is classified by Ethnologue as a separate language, iso 639-3: huh, and as nearly extinct.\nThe recordings are restricted to a single domain: primary, preventive, and treatment health care, including both Western and Mapuche traditional medicine. The recording sessions were conducted as interactive conversations so as to be natural in Mapuche culture, and they were open-ended, following an ethnographic approach. The interviewer was trained in these methods along with the use of the digital recording systems that were available at the time. We also followed human subject protocol. Each person signed a consent form to release the recordings for research purposes and the data have been accordingly anonymized. Because Machi (traditional Mapuche healers) were interviewed, we asked the transcribers to delete any culturally proprietary knowledge that a Machi may have revealed during the conversation. Similarly, we deleted any names or any information that may identify the participants.\nThe corpus is culturally relevant because it was created by Mapuche people, using traditional ways of relating to each other in conversations. They discussed personal experiences with primary health care in the traditional Mapuche system and the Chilean health care system, talking about illnesses and the way they were cured. The participants ranged from 16 years old to 100 years old, almost in equal numbers of men and women, and they were all native speakers of Mapudungun.\nHence, in an effort to provide a relatively “clean” corpus for modern computational experiments, we converted the encoding of the textual transcription from Latin-1 to Unicode, DOS to UNIX line endings, a now more standard text encoding format than what was used when the data was first collected.

        "evidence": "Sarcasm is an intensive, indirect and complex construct that is often intended to express contempt or ridicule . Sarcasm, in speech, is multi-modal, involving tone, body-language and gestures along with linguistic artifacts used in speech. Sarcasm in text, on the other hand, is more restrictive when it comes to such non-linguistic modalities. This makes recognizing textual sarcasm more challenging for both humans and machines.\nSarcasm detection plays an indispensable role in applications like online review summarizers, dialog systems, recommendation systems and sentiment analyzers. This makes automatic detection of sarcasm an important problem. However, it has been quite difficult to solve such a problem with traditional NLP tools and techniques. This is apparent from the results reported by the survey from DBLP:journals/corr/JoshiBC16. The following discussion brings more insights into this.\nConsider a scenario where an online reviewer gives a negative opinion about a movie through sarcasm: “This is the kind of movie you see because the theater has air conditioning”. It is difficult for an automatic sentiment analyzer to assign a rating to the movie and, in the absence of any other information, such a system may not be able to comprehend that prioritizing the air-conditioning facilities of the theater over the movie experience indicates a negative sentiment towards the movie. This gives an intuition to why, for sarcasm detection, it is necessary to go beyond textual analysis.\nWe aim to address this problem by exploiting the psycholinguistic side of sarcasm detection, using cognitive features extracted with the help of eye-tracking. A motivation to consider cognitive features comes from analyzing human eye-movement trajectories that supports the conjecture: Reading sarcastic texts induces distinctive eye movement patterns, compared to literal texts. The cognitive features, derived from human eye movement patterns observed during reading, include two primary feature types:\nThe cognitive features, along with textual features used in best available sarcasm detectors, are used to train binary classifiers against given sarcasm labels. Our experiments show significant improvement in classification accuracy over the state of the art, by performing such augmentation.\nEye-tracking technology has already been utilized by leading mobile technology developers (like Samsung) to facilitate richer user experiences through services like Smart-scroll (where a user’s eye movement determines whether a page has to be scrolled or not) and Smart-lock (where user’s gaze position decides whether to lock the screen or not).",

They provided support for farmers, the unemployed, youth, and the elderly. The New Deal included new constraints and safeguards on the banking industry and efforts to re-inflate the economy after prices had fallen sharply. New Deal programs included both laws passed by Congress as well as presidential executive orders during the first term of the presidency of Franklin D. Roosevelt.\n\nThe programs focused on what historians refer to as the \"3 R's\": relief for the unemployed and for the poor, recovery of the economy back to normal levels, and reform of the financial system to prevent a repeat depression. The New Deal produced a political realignment, making the Democratic Party the majority (as well as the party that held the White House for seven out of the nine presidential terms from 1933 to 1969) with its base in progressive ideas, the South, big city machines and the newly empowered labor unions, and various ethnic groups. The Republicans were split, with progressive Republicans in support but conservatives opposing the entire New Deal as hostile to business and economic growth. The realignment crystallized into the New Deal coalition that dominated presidential elections into the 1960s while the opposing conservative coalition largely controlled Congress in domestic affairs from 1937 to 1964.",

Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such highdimensional vectors is impractical.",
        "evidence": "One of the significant challenges in contemporary information processing is the sheer volume of available data. BIBREF0 , for example, claim that the amount of digital data in the world doubles every two years. This trend underpins efforts to develop algorithms that can efficiently search for relevant information in huge datasets. One class of such algorithms, represented by, e.g., Locality Sensitive Hashing BIBREF1 , relies on hashing data into short, locality-preserving binary codes BIBREF2 . The codes can then be used to group the data into buckets, thereby enabling sublinear search for relevant information, or for fast comparison of data items. Most of the algorithms from this family are data-oblivious, i.e. can generate hashes for any type of data. Nevertheless, some methods target specific kind of input data, like text or image.\nIn this work we focus on learning binary codes for text documents. An important work in this direction has been presented by BIBREF3 . Their semantic hashing leverages autoencoders with sigmoid bottleneck layer to learn binary codes from a word-count bag-of-words (BOW) representation. Salakhutdinov & Hinton report that binary codes allow for up to 20-fold improvement in document ranking speed, compared to real-valued representation of the same dimensionality. Moreover, they demonstrate that semantic hashing codes used as an initial document filter can improve precision of TF-IDF-based retrieval. Learning binary representation from BOW, however, has its disadvantages. First, word-count representation, and in turn the learned codes, are not in itself stronger than TF-IDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such high-dimensional vectors is impractical. Salakhutdinov & Hinton restricted the BOW vocabulary in their experiments to 2000 most frequent words.\nBinary codes have also been applied to cross-modal retrieval where text is one of the modalities. Specifically, BIBREF4 incorporated tag information that often accompany text documents, while BIBREF5 employed siamese neural networks to learn single binary representation for text and image data.\nRecently several works explored simple neural models for unsupervised learning of distributed representations of words, sentences and documents. BIBREF6 proposed log-linear models that learn distributed representations of words by predicting a central word from its context (CBOW model) or by predicting context words given the central word (Skip-gram model). The CBOW model was then extended by BIBREF7 to learn distributed representations of documents. Specifically, they proposed Paragraph Vector Distributed Memory (PV-DM) model, in which the central word is predicted given the context words and the document vector. During training, PV-DM learns the word embeddings and the parameters of the softmax that models the conditional probability distribution for the central words. During inference, word embeddings and softmax weights are fixed, but the gradients are backpropagated to the inferred document vector. In addition to PV-DM, Le & Mikolov studied also a simpler model, namely Paragraph Vector Distributed Bag of Words (PV-DBOW). This model predicts words in the document given only the document vector. It therefore disregards context surrounding the predicted word and does not learn word embeddings. Le & Mikolov demonstrated that paragraph vectors outperform BOW and bag-of-bigrams in information retrieval task, while using only few hundreds of dimensions. These models are also amendable to learning and inference over large vocabularies. Original CBOW network used hierarchical softmax to model the probability distribution for the central word. One can also use noise-contrastive estimation BIBREF8 or importance sampling BIBREF9 to approximate the gradients with respect to the softmax logits.\nAn alternative approach to learning representation of pieces of text has been recently described by BIBREF10 . Networks proposed therein, inspired by the Skip-gram model, learn to predict surrounding sentences given the center sentence. To this end, the center sentence is encoded by an encoder network and the surrounding sentences are predicted by a decoder network conditioned on the center sentence code. Once trained, these models can encode sentences without resorting to backpropagation inference. However, they learn representations at the sentence level but not at the document level.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PV-DM that learn short binary codes for text documents. One inspiration for binary paragraph vectors comes from a recent work by BIBREF11 on learning binary codes for images. Specifically, we introduce a sigmoid layer to the paragraph vector models, and train it in a way that encourages binary activations. We demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes. We also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora. Finally, we study models that simultaneously learn short binary codes for document filtering and longer, real-valued representations for ranking. While BIBREF11 employed a supervised criterion to learn image codes, binary paragraph vectors remain unsupervised models: they learn to predict words in documents.\nFirst, word-count representation, and in turn the learned codes, are not in itself stronger than TFIDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions.

A summary is created by selecting the top entries of the ranked list of sentences. Since the sentences are often treated separately, these models might allow redundancy in the summary. Therefore, they are often extended by an anti-redundancy filter while de-queuing ranked sentence lists.\nOther approaches work at summary-level rather than sentence-level and aim to optimize functions of sets of sentences to find good summaries, such as KL-divergence between probability distributions BIBREF3 or submodular functions that represent coverage, diversity, etc. BIBREF4 \nThe centroid-based model belongs to the former group: it represents sentences as bag-of-word (BOW) vectors with TF-IDF weighting and uses a centroid of these vectors to represent the whole document collection BIBREF5 . The sentences are ranked by their cosine similarity to the centroid vector. This method is often found as a baseline in evaluations where it usually is outperformed BIBREF0 , BIBREF6 .\nThis baseline can easily be adapted to work at the summary-level instead the sentence level. This is done by representing a summary as the centroid of its sentence vectors and maximizing the similarity between the summary centroid and the centroid of the document collection. A simple greedy algorithm is used to find the best summary under a length constraint.\nIn order to keep the method efficient, we outline different methods to select a small number of candidate sentences from each document in the input collection before constructing the summary.\nWe test these modifications on the DUC2004 dataset for multi-document summarization. The results show an improvement of Rouge scores over the original centroid method. The performance is on par with state-of-the-art methods which shows that the similarity between a summary centroid and the input centroid is a well-suited function for global summary optimization.\nThe summarization approach presented in this paper is fast, unsupervised and simple to implement. Nevertheless, it performs as well as more complex state-of-the-art approaches in terms of Rouge scores on the DUC2004 dataset. It can be used as a strong baseline for future research or as a fast and easy-to-deploy summarization tool.\nWe test these modifications on the DUC2004 dataset for multi-document summarization.",

        "question": "Given this paragraph about Thanjavur paintings and its origins, what are the typical features of Thanjavur paintings?",
        "evidence": "Thanjavur painting is a classical South Indian painting style, which was inaugurated from the town of Thanjavur (anglicized as Tanjore) in Tamil Nadu. The art form draws its immediate resources and inspiration from way back about 1600 AD, a period when the Nayakas of Thanjavur under the suzerainty of the Vijayanagara Rayas encouraged art—chiefly, classical dance and music—as well as literature, both in Telugu and Tamil and painting of chiefly Hindu religious subjects in temples. It is distinguished by its famous gold coating. However, it can safely be surmised that Thanjavur painting, as we know it now, originated in the Maratha court of Thanjavur (1676–1855).It has been recognized as a Geographical indication by the Government of India in 2007–08. Thanjavur paintings are characterized by rich and vivid colors, simple icon composition, glittering gold foils overlaid on delicate but extensive gesso work and inlay of glass beads and pieces or precious and semi-precious gems. In Thanjavur paintings one can see the influence of Deccani, Vijayanagar, Maratha and even European or Company styles of painting. Essentially serving as devotional icons, the subjects of most paintings are Hindu gods, goddesses, and saints. Episodes from Hindu Puranas, Sthala-puranas and other religious texts were visualized, sketched or traced and painted with the main figure or figures placed in the central section of the picture (mostly within an architecturally delineated space such as a mantapa or prabhavali) surrounded by several subsidiary figures, themes and subjects. There are also many instances when Jain, Sikh, Muslim, other religious and even secular subjects were depicted in Tanjore paintings. Thanjavur paintings are panel paintings done on wooden planks, and hence referred to as Palagai padam in local parlance. In modern times, these paintings have become souvenirs for festive occasions in South India.",
        "answer": "Thanjavur paintings are easily discernible from the gold coating on wooden panels which form the base. They are characterized by  vivid colors, simple composition of icons along with usage of glass beads and at times precious stones.

An annotation (irrespective of the context) is a note added by way of explanation or commentary. Once a genome is sequenced, it needs to be annotated to make sense of it. Genes in a eukaryotic genome can be annotated using various annotation tools such as FINDER. A modern annotation pipeline can support a user-friendly web interface and software containerization such as MOSGA. Modern annotation pipelines for prokaryotic genomes are Bakta, Prokka and PGAP.\n\nFor DNA annotation, a previously unknown sequence representation of genetic material is enriched with information relating genomic position to intron-exon boundaries, regulatory sequences, repeats, gene names and protein products. This annotation is stored in genomic databases such as Mouse Genome Informatics, FlyBase, and WormBase. Educational materials on some aspects of biological annotation from the 2006 Gene Ontology annotation camp and similar events are available at the Gene Ontology website.\n\nThe National Center for Biomedical Ontology develops tools for automated annotation of database records based on the textual descriptions of those records.\n\nAs a general method, dcGO has an automated procedure for statistically inferring associations between ontology terms and protein domains or combinations of domains from the existing gene/protein-level annotations.",

Originally called Mishawum by the Massachusett tribe, it is located on a peninsula north of the Charles River, across from downtown Boston, and also adjoins the Mystic River and Boston Harbor waterways. Charlestown was laid out in 1629 by engineer Thomas Graves, one of its earliest settlers, during the reign of Charles I of England. It was originally a separate town and the first capital of the Massachusetts Bay Colony.\n\nCharlestown became a city in 1848 and was annexed by Boston on January 5, 1874. With that, it also switched from Middlesex County, to which it had belonged since 1643, to Suffolk County. It has had a substantial Irish-American population since the migration of Irish people during the Great Irish Famine of the 1840s. Since the late 1980s, the neighborhood has changed dramatically because of its proximity to downtown and its colonial architecture. A mix of yuppie and upper-middle-class gentrification has influenced much of the area, as it has in many of Boston's neighborhoods, but Charlestown still maintains a strong Irish-American population.\n\nIn the 21st century, Charlestown's diversity has expanded dramatically, along with growing rates of the very poor and very wealthy. Today Charlestown is a largely residential neighborhood, with much housing near the waterfront, overlooking the Boston skyline.

        "question": "On what benchmark datasets do they evaluate the method?",
        "answer": "SNLI, MultiNLI, Quora Question Pairs, and SST.",
        "evidence": "We propose a method of stacking multiple long short-term memory (LSTM) layers for modeling sentences. In contrast to the conventional stacked LSTMs where only hidden states are fed as input to the next layer, our architecture accepts both hidden and memory cell states of the preceding layer and fuses information from the left and the lower context using the soft gating mechanism of LSTMs. Thus the proposed stacked LSTM architecture modulates the amount of information to be delivered not only in horizontal recurrence but also in vertical connections, from which useful features extracted from lower layers are effectively conveyed to upper layers. We dub this architecture Cell-aware Stacked LSTM (CAS-LSTM) and show from experiments that our models achieve state-of-the-art results on benchmark datasets for natural language inference, paraphrase detection, and sentiment classification.\nFor the evaluation of performance of the proposed method on the NLI task, SNLI BIBREF22 and MultiNLI BIBREF23 datasets are used. The objective of both datasets is to predict the relationship between a premise and a hypothesis sentence: entailment, contradiction, and neutral. SNLI and MultiNLI datasets are composed of about 570k and 430k premise-hypothesis pairs respectively.\nGloVe pretrained word embeddings BIBREF49 are used and remain fixed during training. The dimension of encoder states ( INLINEFORM0 ) is set to 300 and a 1024D MLP with one or two hidden layers is used. We apply dropout BIBREF50 to the word embeddings and the MLP layers. The features used as input to the MLP classifier are extracted following Eq. EQREF28 .\nTable TABREF32 and TABREF33 contain results of the models on SNLI and MultiNLI datasets. In SNLI, our best model achieves the new state-of-the-art accuracy of 87.0% with relatively fewer parameters. Similarly in MultiNLI, our models match the accuracy of state-of-the-art models in both in-domain (matched) and cross-domain (mismatched) test sets. Note that only the GloVe word vectors are used as word representations, as opposed to some models that introduce character-level features. It is also notable that our proposed architecture does not restrict the selection of pooling method; the performance could further be improved by replacing max-pooling with other advanced algorithms e.g. intra-sentence attention BIBREF39 and generalized pooling BIBREF19 .\nWe use Quora Question Pairs dataset BIBREF24 in evaluating the performance of our method on the PI task. The dataset consists of over 400k question pairs, and each pair is annotated with whether the two sentences are paraphrase of each other or not.\nSimilar to the NLI experiments, GloVe pretrained vectors, 300D encoders, and 1024D MLP are used. The number of CAS-LSTM layers is fixed to 2 in PI experiments. Two sentence vectors are aggregated using Eq. EQREF29 and fed as input to the MLP. The results on the Quora Question Pairs dataset are summarized in Table TABREF34 . Again we can see that our models outperform other models by large margin, achieving the new state of the art.\nIn evaluating sentiment classification performance, the Stanford Sentiment Treebank (SST) BIBREF25 is used. It consists of about 12,000 binary-parsed sentences where constituents (phrases) of each parse tree are annotated with a sentiment label (very positive, positive, neutral, negative, very negative). Following the convention of prior work, all phrases and their labels are used in training but only the sentence-level data are used in evaluation.\nIn evaluation we consider two settings, namely SST-2 and SST-5, the two differing only in their level of granularity with regard to labels. In SST-2, data samples annotated with `neutral' are ignored from training and evaluation. The two positive labels (very positive, positive) are considered as the same label, and similarly for the two negative labels. As a result 98,794/872/1,821 data samples are used in training/validation/test, and the task is considered as a binary classification problem. In SST-5, data are used as-is and thus the task is a 5-class classification problem. All 318,582/1,101/2,210 data samples for training/validation/test are used in the SST-5 setting.\nWe use 300D GloVe vectors, 2-layer 150D or 300D encoders, and a 300D MLP classifier for the models, however unlike previous experiments we tune the word embeddings during training. The results on SST are listed in Table TABREF35 . Our models achieve the new state-of-the-art accuracy on SST-2 and competitive accuracy on SST-5, without utilizing parse tree information.\nWe dub this architecture Cellaware Stacked LSTM (CAS-LSTM) and show from experiments that our models bring significant performance gain over the standard LSTMs on benchmark datasets for natural language inference, paraphrase detection, sentiment classification, and machine translation.****For the evaluation of performance of the proposed method on the NLI task, SNLI (Bowman et al., 2015) and MultiNLI (Williams et al., 2018b) datasets are used.****We use Quora Question Pairs dataset (Wang et al., 2017) in evaluating the performance of our method on the PI task.****In evaluating sentiment classification performance, the Stanford Sentiment Treebank (SST) (Socher et al., 2013) is used.",

Most of his time spent in Seattle was as a backup to point guard Gary Payton, who was considered to be a much more competent ball handler and defender, as Barros was deemed more usable at shooting guard. Prior to the 1993–94 season, the Sonics traded Barros to the Charlotte Hornets in exchange for Kendall Gill. Two days later, Charlotte traded Barros, Sidney Green, and their 1993 draft choice, Greg Graham, to the Philadelphia 76ers for Hersey Hawkins. Barros became a free agent at the end of the 1994-95 NBA season. He signed with his hometown Boston Celtics, and remained for five seasons as a role player alongside David Wesley and Dee Brown and mentor to younger players such as Antoine Walker and Paul Pierce. In the offseason of 2000, Barros was traded to the Dallas Mavericks as part of a four-team deal that also involved the Utah Jazz and Golden State Warriors.

Various equivalent notions of compactness, such as sequential compactness and limit point compactness, can be developed in general metric spaces.\n\nIn contrast, the different notions of compactness are not equivalent in general topological spaces, and the most useful notion of compactness — originally called bicompactness — is defined using covers consisting of open sets (see Open cover definition below). That this form of compactness holds for closed and bounded subsets of Euclidean space is known as the Heine–Borel theorem. Compactness, when defined in this manner, often allows one to take information that is known locally — in a neighbourhood of each point of the space — and to extend it to information that holds globally throughout the space. An example of this phenomenon is Dirichlet's theorem, to which it was originally applied by Heine, that a continuous function on a compact interval is uniformly continuous; here, continuity is a local property of the function, and uniform continuity the corresponding global property.",

The goal of question generation (QG) is to generate a question that asks towards the answer with the given passage and the expected answer. In the following experiments, we extend the QG task to the cross-lingual setting. By only using English QG training data, our goal is to generate questions in English or Chinese with the given passage-answer pair in English or Chinese.\nWe use SQuAD 1.1 BIBREF30 as the English QG dataset. It is a popular English question answering dataset containing over 100,000 questions and their corresponding annotated passages. Following BIBREF31, we regard the original development set as the test set, and sample 5000 examples from the training data of two datasets as the development sets. For Chinese QG, we follow the default data splits of WebQA BIBREF32. We regard the provided annotated evidence sentences as the input passages instead of entire documents. To construct the input sequence, we view the whole input passage as a single sentence, and concatenate the passage and the answer into one sequence with a special token S between them. During decoding Chinese, we utilize a subset of vocabulary, which is obtained from the passage sentences of the WebQA dataset.\nWe first conduct experiments on the supervised English-English QG setting. We compare our model to the following baselines:\nCorefNqg BIBREF33 A sequence-to-sequence model with attention mechanism and a feature-rich encoder.\nMp-Gsn BIBREF31 A sequence-to-sequence model with gated self-attention and maxout pointer mechanism.\nXlm BIBREF5 The current state-of-the-art cross-lingual pre-training model.

As shown in Table TABREF16, our model outperforms the baselines, which demonstrates that our pre-trained model provides a good initialization for NLG.\nWe conduct experiments on the zero-shot Chinese-Chinese QG task to evaluate the cross-lingual transfer ability. In this task, models are trained with English QG data but evaluated with Chinese QG examples. We include the following models as our baselines:\nXlm Fine-tuning XLM with the English QG data.\nPipeline (Xlm) The pipeline of translating input Chinese sentences into English first, then performing En-En-QG with the XLM model, and finally translating back to the Chinese. We use the Transformer as the translator, which is also trained on the MultiUN dataset.\nPipeline (Xlm) with Google Translator Same to Pipeline (Xlm) but using Google Translator to translate the texts.\nWe evaluate models by both automatic evaluation metrics and human experts. The automatic metrics scores are computed by regarding each Chinese character as a token. For human evaluation, we consider three metrics for the generated questions: relatedness, fluency, and correctness, which are represented as integers ranged from 1 to 3. We randomly select 100 passage-answer pairs from the English QG test set, and use the models to generate questions. Then we present these examples to three experts to ask for the above scores. In Table TABREF17 and Table TABREF18, we present the results for the zero-shot Zh-Zh-QG. The results of monolingual supervised models are also reported in Table TABREF16 as reference. In the automatic evaluation, our model consistently performs better than baselines in both zero-shot and monolingual supervised setting. In the human evaluation, our model also obtains significant improvements in terms of relatedness and correctness.\nIn the zero-shot English-Chinese question generation experiments, we use Xlm and Pipeline (Xlm) as our baselines. Pipeline (Xlm) is a pipeline method that uses En-En-QG with Xlm to generate questions, and then translates the results to Chinese. Because there is no annotations for En-Zh-QG, we perform human evaluation studies for this setting. Table TABREF19 shows the human evaluation results, where our model surpasses all the baselines especially in terms of relatedness and correctness.\nWe also conduct experiments for zero-shot Chinese-English question generation, and adopt the same evaluation procedure to En-Zh-QG. Pipeline (Xlm) first translates Chinese input to English, and then conduct En-En-QG with Xlm. As shown in Table TABREF20, human evaluation results indicate that Xnlg achieves significant improvements on the three metrics.\nWe evaluate models with BLEU-4 (BL-4), ROUGE (RG) and METEOR (MTR) metrics.",

        "answer": "An approach to  training a Chinese Named Entity Recognition (NER) system  on the crowd-annotated data.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data.",

The Federal Reserve, or the Fed, is specifically tasked with maintaining maximum employment while ensuring price stability. The United States is currently experiencing persistent inflation. Typically, the Federal Reserve will raise interest rates when initially trying to combat inflation. The increased rates make lending more expensive, and subsequently discourages capital investment and borrowing. The added cost in turn reduces demand for products and services. Lower demand normally leads to dropping prices to try and motivate potential buyers. The other primary method involves open-market operations. When inflation is running higher than expected, the Fed can reduce the money supply by selling securities and taking currency out of circulation.

        "evidence": "Rahul Sharad Dravid (/ˌrɑːhʊl drəvɪd/ (listen); born 11 January 1973) is an Indian cricket coach and former captain of the Indian national team, currently serving as its head coach. Prior to his appointment to the senior men's national team, Dravid was the Head of Cricket at the National Cricket Academy (NCA), and the head coach of the India Under-19 and India A teams. Under his tutelage, the under-19 team finished runners up at the 2016 U-19 Cricket World Cup and won the 2018 U-19 Cricket World Cup. Known for his sound batting technique, Dravid scored 24,177 runs in international cricket and is widely regarded as one of the greatest batsmen in the history of cricket. He is colloquially known as Mr. Dependable and often referred to as The Wall. With India, he helped the team to be one of the joint-winners of the 2002 ICC Champions Trophy, where the title was shared with Sri Lanka.\n\nBorn in a Marathi family and raised in Bangalore, he started playing cricket at the age of 12 and later represented Karnataka at the under-15, under-17 and under-19 levels. Dravid was named one of the best five cricketers of the year by Wisden Cricketers' Almanack in 2000 and received the Player of the Year and the Test Player of the Year awards at the inaugural ICC awards ceremony in 2004. In December 2011, he became the first non-Australian cricketer to deliver the Bradman Oration in Canberra.\n\nAs of January 2022, Dravid is the fourth-highest run scorer in Test cricket, after Sachin Tendulkar, Ricky Ponting and Jacques Kallis. In 2004, after completing his century against Bangladesh in Chittagong, he became the first player to score a century in all the ten Test-playing countries (now 12). As of October 2012, he holds the record for the most catches taken by a player (non-wicket-keeper) in Test cricket, with 210. Dravid holds a unique record of never getting out for a Golden duck in the 286 Test innings which he has played. He has faced 31258 balls, which is the highest number of balls faced by any player in test cricket. He has also spent 44152 minutes at the crease, which is the highest time spent on crease by any player in test cricket. Dravid and Sachin Tendulkar are currently the highest scoring partnership in Test cricket history having scored 6920 runs combined when batting together for India.\n\nIn August 2011, after receiving a surprise recall in the ODI series against England, Dravid declared his retirement from ODIs as well as Twenty20 International (T20I), and in March 2012, he announced his retirement from international and first-class cricket. He appeared in the 2012 Indian Premier League as captain of the Rajasthan Royals.\n\nRahul Dravid, along with Glenn McGrath were honoured during the seventh annual Bradman Awards function in Sydney on 1 November 2012. Dravid has also been honoured with the Padma Shri and the Padma Bhushan award, India's fourth and third highest civilian awards respectively.\n\nIn 2014, Rahul Dravid joined the GoSports Foundation, Bangalore as a member of their board of advisors. In collaboration with GoSports Foundation he is mentoring India's future Olympians and Paralympians as part of the Rahul Dravid Athlete Mentorship Programme. Indian badminton player Prannoy Kumar, Para-swimmer Sharath Gayakwad and young Golfer S. Chikkarangappa were part of the initial group of athletes to be mentored by Rahul Dravid.

Most important steps that could lead to quality issues are around managing moisture while protein cooks. Especially when you use chicken. Chicken tends to release a lot of moisture and that can spoil the dish. A recommendation would be to cook all of the chicken 50% through without any seasoning in a separate pot. It'll release significant moisture in this process. Once done, you can then separate out chicken from the stock and use the chicken for Biryani. One of the other gotcha while cooking Biryani is while preparing rice. Rice should never be fully cooked before it's mixed with chicken. Remember that rice and seasoned chicken has to be cooked together for several minutes. To get best results make sure you cook rice in boiling water only 70% through. It should be bit uncooked. Then use that rice to mix with seasoned chicken and continue following the Biryani recipe from that point onwards.",

        "answer": "Stars that have a higher mass than about 2.2 solar masses (the mass of our Sun) will typically collapse into black holes at the end of their life cycle when fusion has stopped and no longer pushes out against the inward pull of gravity. For stars of this mass, their inward pull of gravity is too strong to be resisted by other forces, thus their fate is to become black holes. However, stars under this limit and above the Chandrasekhar limit of 1.4 solar masses will end their lifecycles as neutron stars. Neutron stars are also the remnants of dead stars but since they have a smaller mass, their gravity is not enough for them to cross into becoming black holes. As the dead star compresses and becomes more and more dense, regular matter is turned into neutrons and the last force to resist the pull of gravity is called degenerate neutron pressure, which is a quantum effect that dictates that no two neutrons may be in the same quantum state. This creates an outward pressure that resists the pull of gravity and settles the star into a neutron star. If more mass is added later, from a star companion or other sources, once the star's mass crosses the limit of around 2.2 solar masses even degenerate neutron pressure isn't enough to balance gravity and the star will collapse into a black hole.",

Fake news is misinformation masked under the guise of a real news article, and is used to deceptively influence people’s beliefs.\nFor this report, we are classifying news articles as “real” or “fake”, which will be a binary classification problem - classifying the samples as a positive (with fake news) or negative (not fake news) sample. Many studies have used machine learning algorithms and build classifiers based on features like content, the author’s name and job-title, using lots of models like the convolutional neural network (CNN), recurrent neural network (RNN), feed-forward neural network (FFNN), long-short term memory (LSTM) and logistic regression to find the most optimal model and return its results. In [1], the author built a classifier using natural language processing and used models like CNN, RNN, FFNN, and Logistic Regression and concluded that the CNN classifiers could not be as competitive as the RNN classifiers. The authors in [2] think that their study can be improved by having more features like knowing the history of lies spoken by the news reporter or the speaker.\nMoreover, apart from the traditional machine learning methods, new models have also been developed. One of the newer models, TraceMiner, creates an LSTM-RNN model inferring from the embedding of social media users in the social network structure to propagate through the path of messages and has provided high classification accuracy$^{5}$. FAKEDETECTOR is another inference model developed to detect the credibility of the fake news which is considered to be quite reliable and accurate$^{7}$.\nThere also have been studies that have a different approach. A paper surveys the current state-of-the-art technologies that are imperative when adopting and developing fake news detection and provides a classification of several accurate assessment methods that analyze the text and detect anomalies$^{3}$.\nThese previous approaches lack a clear contextual analysis used in NLP. We considered the semantic meaning of each word and we feel that the presence of particular words influence the meaning. We reckoned this important since we felt the contextual meaning of the text needs to be preserved and analyzed for better classification. Other studies emphasize the user and features related to them. In [4], “45 features…[were used] for predicting accuracy...across four types: structural, user, content, and temporal,” so features included characteristics beyond the text. Article [6] \"learn[s] the representations of news articles, creators and subjects simultaneously.\" In our project, we emphasize the content by working with articles whose labels only relate to the text, nothing outside that scope, and have used SVM, Logistic Regression, ANN, LSTM, and Random Forest.\nWe had devised this problem into 3 different phases: pre-processing, text-to-numeric representation conversion using pre-trained algorithms, and then evaluate the models using state-of-the-art machine learning algorithms. We had analysed the data set and in particular the text part of the data explaining how it is distributed and then we converted each text into numeric representation using pre-training models such as TFIDF, CV and W2V for vector representation. Finally, we evaluated our numeric conversion data using significant machine learning algorithms such as neural networks, classification algorithms etc to perform the classification.\nFor this report, we are exploring the field of natural language processing, which is the broad study of how computers and machines can understand human to human communication and how texts are analyzed based on contextual information by machines.",

        "evidence": "Image manipulation aims to modify some aspects of given images, from low-level colour or texture BIBREF0, BIBREF1 to high level semantics BIBREF2, to meet a user's preferences, which has numerous potential applications in video games, image editing, and computer-aided design. Recently, with the development of deep learning and deep generative models, automatic image manipulation has made remarkable progress, including image inpainting BIBREF3, BIBREF4, image colourisation BIBREF1, style transfer BIBREF0, BIBREF5, and domain or attribute translation BIBREF6, BIBREF7.\nAll the above works mainly focus on specific problems, and few studies BIBREF8, BIBREF9 concentrate on more general and user-friendly image manipulation by using natural language descriptions. More precisely, the task aims to semantically edit parts of an image according to the given text provided by a user, while preserving other contents that are not described in the text. However, current state-of-the-art text-guided image manipulation methods are only able to produce low-quality images (see Fig. FIGREF1: first row), far from satisfactory, and even fail to effectively manipulate complex scenes (see Fig. FIGREF1: second row).\nTo achieve effective image manipulation guided by text descriptions, the key is to exploit both text and image cross-modality information, generating new attributes matching the given text and also preserving text-irrelevant contents of the original image. To fuse text and image information, existing methods BIBREF8, BIBREF9 typically choose to directly concatenate image and global sentence features along the channel direction. Albeit simple, the above heuristic may suffer from some potential issues. Firstly, the model cannot precisely correlate fine-grained words with corresponding visual attributes that need to be modified, leading to inaccurate and coarse modification. For instance, shown in the first row of Fig. FIGREF1, both models cannot generate detailed visual attributes like black eye rings and a black bill. Secondly, the model cannot effectively identify text-irrelevant contents and thus fails to reconstruct them, resulting in undesirable modification of text-irrelevant parts in the image. For example, in Fig. FIGREF1, besides modifying the required attributes, both models BIBREF8, BIBREF9 also change the texture of the bird (first row) and the structure of the scene (second row).\nTo address the above issues, we propose a novel generative adversarial network for text-guided image manipulation (ManiGAN), which can generate high-quality new attributes matching the given text, and at the same time effectively reconstruct text-irrelevant contents of the original image. The key is a text-image affine combination module (ACM) where text and image features collaborate to select text-relevant regions that need to be modified, and then correlate those regions with corresponding semantic words for generating new visual attributes semantically aligned with the given text description. Meanwhile, it also encodes original image representations for reconstructing text-irrelevant contents. Besides, to further enhance the results, we introduce a detail correction module (DCM) which can rectify mismatched attributes and complete missing contents. Our final model can produce high-quality manipulation results with fine-grained details (see Fig. FIGREF1: Ours).\nFinally, we suggest a new metric to assess image manipulation results. The metric can appropriately reflect the performance of image manipulation, in terms of both the generation of new visual attributes corresponding to the given text, and the reconstruction of text-irrelevant contents of the original image. Extensive experiments on the CUB BIBREF10 and COCO BIBREF11 datasets demonstrate the superiority of our model, where our model outperforms existing state-of-the-art methods both qualitatively and quantitatively.\nTo address the above issues, we propose a novel generative adversarial network for text-guided image manipulation (ManiGAN), which can generate high-quality new attributes matching the given text, and at the same time effectively reconstruct text-irrelevant contents of the original image.",

The convenience does come at a cost since air acts as a shared medium which limits both the number of clients a WiFi network can support as well as the bandwidth available to those clients.",

        "answer": "It contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nOur dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks.",

In 1923, he was appointed leader of the Berlin Philharmonic Orchestra, but in 1931 he moved to Manchester as a Professor at the Royal Manchester College of Music.\n\nThe move to Manchester led to the formation of the Henry Holst String Quartet with Charles Taylor (second violin), Herbert Downes (viola) and Anthony Pini (cello). The ensemble was recognised as fine quartet, touring extensively in the UK and broadcasting on BBC Radio. They played a number of times in Liverpool for the Rodewald Concert Society in the 1934 and 1937 seasons.\n\nErnest Element (2nd violin) and Frank Venton (viola) also sometimes played for the quartet. Herbert Downes left to lead his own quartet in 1935. Charles Taylor also left to found his own quartet and was replaced by Reginald Stead as second violin. Reginald Stead later became the leader of the BBC Northern Orchestra. Anthony Pini joined the London Philharmonic Orchestra in 1932 and was replaced by John C Hock as cellist. The Henry Holst Quartet finally disbanded when Henry Holst formed the Philharmonia Quartet in 1941 at the instigation of Walter Legge to record for Columbia Records.",

        "answer": "This article lists English association football clubs whose men's sides have won competitive honours run by official governing bodies. Friendly competitions and matches organized between clubs are not included. The football associations FIFA and UEFA run international and European competitions; while The Football Association, and its mostly self-governing subsidiary bodies the English Football League and Premier League, run national competitions.\n\nThe European governing body UEFA was founded in 1954, and created their first and most prestigious competition, the European Cup, the next year. It was expanded and renamed in 1992 as the UEFA Champions League. Liverpool hold the English record, with six wins. Parallel to UEFA, various officials created the Inter-Cities Fairs Cup in 1955, but this competition was disbanded when UEFA created the replacement tournament, UEFA Cup, in 1971 (renamed the UEFA Europa League in 2009) The English record number of Europa League wins is three, also held by Liverpool. Another competition absorbed into the UEFA Cup, in 1999, was the UEFA Cup Winners' Cup, which was created in 1960 and featured the winners of national knockout competitions The winners of this competition played the European Cup winners in the UEFA Super Cup, starting in 1972 (recognised by UEFA in 1973), which now features the winners of the Champions League and Europa League.Liverpool also hold the English record, with four wins, in the UEFA Super Cup. The International Football Cup, also known as the UEFA Intertoto Cup, was a competition for clubs not participating in the European Cup, UEFA Cup or Cup Winners' Cup. The tournament commenced in 1961, but UEFA officially recognised it only in 1995, and discontinued in 2008, with the Europa League expanded to accommodate Intertoto Cup clubs. UEFA and CONMEBOL also created an intercontinental competition in 1960, the Intercontinental Cup, featuring continental champions from both associations. In 2000, the international governing body FIFA created the FIFA Club World Cup and in 2004 the Intercontinental Cup was merged into it. Manchester United are the only English club to have won the Intercontinental Cup, while United, Chelsea and Liverpool are the only English teams to have lifted the Club World Cup.\n\nEngland's first competition organised by a national body, the FA Cup, began in the 1871–72 season, making it one of the oldest football competitions in the world.Arsenal hold the record number of wins, with 14. League football began in the next decade with the founding of The Football League in 1888–89. The name First Division was adopted in 1892, when The Football League gained a second division. The First Division remained the highest division of the English league system until 1992, when the Premier League was founded. Manchester United have won the most top division titles, 20. The English equivalent of the super cup began in 1898 with the inauguration of the Sheriff of London Charity Shield, pitting the best professional and amateur sides of the year against each other. The trophy would develop into the FA Charity Shield in 1908, which was later renamed the FA Community Shield in 2002. Manchester United also hold the record here, with 21 wins. The Football League created its own knockout competition in 1960, the League Cup. Its current record is nine wins, held by Liverpool. The Anglo-Italian League Cup was created in 1969 to match English cup winners against the winners of the Coppa Italia, and was permanently disbanded in 1976. In 1985, the Full Members' Cup and Football League Super Cup were created as substitutes for UEFA competitions after UEFA responded to the Heysel Stadium disaster by banning English clubs. They finished in 1992 and 1986, respectively. The Football League Centenary Trophy marked The Football League's 100th birthday, in the 1988–89 season \n\nLower down in the hierarchy of English football are many other competitions, not included in the tables on this page. These include competitions run by the above national governing bodies, but organised for clubs ineligible for higher competitions. For example, the Texaco Cup and EFL Trophy. Regional competitions are organised by County Football Associations. In the years when league football was unavailable or only available to northern and midlands clubs, the county competitions coexisted with the FA Cup as the main tournaments for clubs. Nowadays, county cups are contested by lower or regional division teams and those that still participate generally field youth or reserve sides.",

You could also use newspaper (or any paper), dryer lint, or cardboard. For kindling, use smaller pieces of wood, such as twigs and sticks no thicker than 1 inch in diameter (about the thickness of your thumb). Dry or well-seasoned logs will ensure a good burn. Stack the wood in a way that guarantees oxygen can easily reach your flame. Many prefer a teepee or log cabin stacking design. Now, use a heat source to create a flame or spark and apply this to your tinder. Once the tinder combusts, it should light the kindling, and the kindling should eventually ignite your logs.

The SST dataset consists of 8544 movie reviews, with a vocabulary of over 16K words. As a background corpus, we use the IMDB movie reviews BIBREF25 , which contain 54K movie reviews, and a vocabulary of over 78K words. The two datasets do not share any reviews in common. The spell-correction models are evaluated on their ability to correct misspellings. The test setting consists of reviews where each word (with length $\\ge 4$ , barring stopwords) is attacked by one of the attack types (from swap, add, drop and keyboard attacks). In the all attack setting, we mix all attacks by randomly choosing one for each word. This most closely resembles a real world attack setting.\nIn addition to our word recognition models, we also compare to After The Deadline (ATD), an open-source spell corrector. We found ATD to be the best freely-available corrector. We refer the reader to BIBREF7 for comparisons of ScRNN to other anonymized commercial spell checkers.\nFor the ScRNN model, we use a single-layer Bi-LSTM with a hidden dimension size of 50. The input representation consists of 198 dimensions, which is thrice the number of unique characters (66) in the vocabulary. We cap the vocabulary size to 10K words, whereas we use the entire vocabulary of 78470 words when we backoff to the background model. For training these networks, we corrupt the movie reviews according to all attack types, i.e., applying one of the 4 attack types to each word, and trying to reconstruct the original words via cross entropy loss.\nWe calculate the word error rates (WER) of each of the models for different attacks and present our findings in Table 2 . Note that ATD incorrectly predicts $11.2$ words for every 100 words (in the `all' setting), whereas, all of the backoff variations of the ScRNN reconstruct better. The most accurate variant involves backing off to the background model, resulting in a low error rate of $6.9\\%$ , leading to the best performance on word recognition. This is a $32\\%$ relative error reduction compared to the vanilla ScRNN model with a pass-through backoff strategy. We can attribute the improved performance to the fact that there are $5.25\\%$ words in the test corpus that are unseen in the training corpus, and are thus only recoverable by backing off to a larger corpus. Notably, only training on the larger background corpus does worse, at $8.7\\%$ , since the distribution of word frequencies is different in the background corpus compared to the foreground corpus.\nThe SST dataset consists of 8544 movie reviews, with a vocabulary of over 16K words.",

Many residents of this sparsely populated region resent the control of these lands by distant bureaucrats whose regulations place significant restrictions on how the land is used. For this reason, movements have been ongoing for many years to work for the transfer of those lands to local authorities. While this sense of disenfranchisement is understandable, the truth is that local residents would suffer more from the loss of centralized management of these lands than they would gain through local control. This region is mostly desert, a landscape and ecosystem that is unusually vulnerable to degradation. Without the concerted efforts of an administration that can apply consistent regulation and stewardship of these lands across a broad territory that crosses state boundaries, the value of these lands to local residents would decline even further, becoming less productive and less attractive to the hunters, fishermen, and other tourists whose spending represents the majority of income for many of these Intermountain communities.",

        "answer": "One challenge medical search engines face is the segmentation of individual clinical entities. When a user query consists of multiple clinical entities, a search engine would often fail to recognize them as separate entities.",
        "evidence": "Medical search engines are an essential component for many online medical applications, such as online diagnosis systems and medical document databases. A typical online diagnosis system, for instance, relies on a medical search engine. The search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem. One challenge medical search engines face is the segmentation of individual clinical entities. When a user query consists of multiple clinical entities, a search engine would often fail to recognize them as separate entities. For example, the user query “fever joint pain weight loss headache” contains four separate clinical entities: “fever”, “joint pain”, “weight loss”, and “headache”. But when the search engine does not recognize them as separate entities and proceeds to retrieve results for each word in the query, it may find \"pain\" in body locations other than \"joint pain\", or it may miss \"headache\" altogether, for example. Some search engines allow the users to enter a single clinical concept by selecting from an auto-completion pick list. But this could also result in retrieving inaccurate or partial results and lead to poor user experience.\nWe want to improve the medical search engine so that it can accurately retrieve all the relevant clinical concepts mentioned in a user query, where relevant clinical concepts are defined with respect to the terminologies the search engine uses. The problem of extracting clinical concept mentions from a user query can be seen as a variant of the Concept Extraction (CE) task in the frequently-cited NLP challenges in healthcare, such as 2010 i2b2/VA BIBREF0 and 2013 ShARe/CLEF Task 1 BIBREF1. Both CE tasks in 2010 i2b2/VA and 2013 ShARe/CLEF Task 1 ask the participants to design an algorithm to tag a set of predefined entities of interest in clinical notes. These entity tagging tasks are also known as clinical Named Entity Recognition (NER). For example, the CE task in 2010 i2b2/VA defines three types of entities: “problem”, “treatment”, and “test”. The CE task in 2013 ShARe/CLEF defines various types of disorder such as “injury or poisoning”, \"disease or syndrome”, etc. In addition to tagging, the CE task in 2013 ShARe/CLEF has an encoding component which requires selecting one and only one Concept Unique Identifier (CUI) from Systematized Nomenclature Of Medicine Clinical Terms (SNOMED-CT) for each disorder entity tagged. Our problem, similar to the CE task in 2013 ShARe/CLEF, also contains two sub-problems: tagging mentions of entities of interest (entity tagging), and selecting appropriate terms from a glossary to match the mentions (term matching). However, several major differences exist. First, compared to clinical notes, the user queries are much shorter, less technical, and often less coherent. Second, instead of encoding, we are dealing with term matching where we rank a few best terms that match an entity, instead of selecting only one. This is because the users who type the queries may not have a clear idea about what they are looking for, or could be laymen who know little terminology, it may be more helpful to provide a set of likely results and let the users choose. Third, the types of entities are different. Each medical search engine may have its own types of entities to tag. There is also one minor difference in the tagging scheme between our problem and the CE task in 2013 ShARe/CLEF - We limit our scope to dealing with entities of consecutive words and not disjoint entities . We use only Beginning, Inside, Outside (BIO) tags. Given the differences listed above, we need to customize a framework consisting of an entity tagging and term matching component for our CE problem.\nOne challenge medical search engines face is the segmentation of individual clinical entities.

Since our paper showed the advantages of using the latent space of a VAE structure in prototype-based explanation methods, we also believe that ImageNet, a larger image dataset such as the one you suggested, is a natural next step.\nSince the scalability issue is important, we will mention the same comment as Answer #1 in the manuscript. We will add this to the last paragraph of section 4.3, which deals with the limitations of our paper.",
        "evidence": "The explanations of our model are divided into basic explanation and explanations of the basic explanation. For fundamental explanations, visualized images of the learned prototypes and the distance between encoded input and prototype distributions are given as previous prototype-based explanation methods. To explain this basic explanation, we additionally provide two gradual explanations. These explanations can be obtained because our method constructs dense explanation space, unlike previous methods. As a result, it is possible to generate interconnection between latent representations as images. We represent changing elements by interpolating these latent representations and define them as relationships.\nThe relationships between inputs and prototypes can be visualized by our model. In situations where distance is given for interpretable information, the factors that can reduce the distance are critical for understanding the model's prediction. Additionally, relationships between prototypes are given. Since the prototypes are representative of the whole dataset, relationships between prototypes show which features are needed to change from one class to another class. This explanation can be used as basic information about how the model discriminates classes.\nAfter the model is trained, basic explanation and explanations for basic explanation are visualized as follows. First, the prototype, provided as the fundamental explanation, is visualized by sending µ i of the prototype distribution through the decoder g as a prototype. Next, the relationships between prototype µ i and prototype µ j are visualized as sending µ i + (µ j − µ i )r/k for r = 0, 1, . . . , k through the decoder g, which can be controlled by increasing the value of k for detailed explanation and decreasing the value of k for a brief explanation. Finally, the relationships between inputs and prototypes are provided in the same way, and visualizations of prototype distributions are based on µ values and σ values.\nThe disadvantage of our model comes from this visualization. Many training samples are required to generate explanation images. In addition, visualized images of our explanations are fundamentally generated through VAE, making it challenging to generate human-recognizable images for complex datasets that are difficult for VAE to generate the observable image. However, this is a problem related to VAE's expressive power, and there are many high-resolution expressive methods based on VAE, so applying these methods would solve these problems in future work.\nThe disadvantage of our model comes from this visualization.

For example, a dialog system can ask for additional information during the dialog.\nWe distinguish three different basic approaches to requesting knowledge bases:\nA combination of the above approaches is also possible. For example, we can imagine scenarios where the dialog system starts with hand-crafted rules, which are subsequently interactively improved through dialogs with its users. With a growing demand for open domain dialog systems, it shows that creating hand-crafted policies does not scale well - therefore, machine learning approaches are gaining on popularity. Many public datasets for offline learning have been published BIBREF8 , BIBREF7 . However, to our knowledge, no public datasets for interactive learning are available.

        "evidence": "Operation Aurora was a series of cyber attacks conducted by advanced persistent threats such as the Elderwood Group based in Beijing, China, with ties to the People's Liberation Army. First publicly disclosed by Google on January 12, 2010, in a blog post, the attacks began in mid-2009 and continued through December 2009.\n\nThe attack was aimed at dozens of other organizations, of which Adobe Systems, Akamai Technologies, Juniper Networks, and Rackspace have publicly confirmed that they were targeted. According to media reports, Yahoo, Symantec, Northrop Grumman, Morgan Stanley, and Dow Chemical were also among the targets.\n\nAs a result of the attack, Google stated in its blog that it plans to operate a completely uncensored version of its search engine in China \"within the law, if at all,\" and acknowledged that if this is not possible, it may leave China and close its Chinese offices. Official Chinese sources claimed this was part of a strategy developed by the U.S. government.\n\nThe attack was named \"Operation Aurora\" by Dmitri Alperovitch, Vice President of Threat Research at cybersecurity company McAfee. Research by McAfee Labs discovered that \"Aurora\" was part of the file path on the attacker's machine that was included in two of the malware binaries McAfee said were associated with the attack. \"We believe the name was the internal name the attacker(s) gave to this operation,\" McAfee Chief Technology Officer George Kurtz said in a blog post.\n\nAccording to McAfee, the primary goal of the attack was to gain access to and potentially modify source code repositories at these high-tech, security, and defense contractor companies. \"[The SCMs] were wide open,\" says Alperovitch. \"No one ever thought about securing them, yet these were the crown jewels of most of these companies in many ways—much more valuable than any financial or personally identifiable data that they may have and spend so much time and effort protecting.\"\n\nHistory\n\nFlowers left outside Google China's headquarters after its announcement it might leave the country\nOn January 12, 2010, Google revealed on its blog that it had been the victim of a cyber attack. The company said the attack occurred in mid-December and originated from China. Google stated that over 20 other companies had been attacked; other sources have since cited that more than 34 organizations were targeted. As a result of the attack, Google said it was reviewing its business in China. On the same day, United States Secretary of State Hillary Clinton issued a brief statement condemning the attacks and requesting a response from China.\n\nOn January 13, 2010, the news agency All Headline News reported that the United States Congress plans to investigate Google's allegations that the Chinese government used the company's service to spy on human rights activists.\n\nIn Beijing, visitors left flowers outside of Google's office. However, these were later removed, with a Chinese security guard stating that this was an \"illegal flower tribute\". The Chinese government has yet to issue a formal response, although an anonymous official stated that China was seeking more information on Google's intentions.\n\nAttackers involved\nFurther information: Cyberwarfare by China\nTechnical evidence including IP addresses, domain names, malware signatures, and other factors, show Elderwood was behind the Operation Aurora attack. The \"Elderwood\" group was named by Symantec (after a source-code variable used by the attackers), and is referred to as the \"Beijing Group\" by Dell Secureworks. The group obtained some of Google's source code, as well as access to information about Chinese activists. Elderwood also targeted numerous other companies in the shipping, aeronautics, arms, energy, manufacturing, engineering, electronics, financial, and software sectors.\n\nThe \"APT\" designation for the Chinese threat actors responsible for attacking Google is APT17.\n\nElderwood specializes in attacking and infiltrating second-tier defense industry suppliers that make electronic or mechanical components for top defense companies. Those firms then become a cyber \"stepping stone\" to gain access to top-tier defense contractors. One attack procedure used by Elderwood is to infect legitimate websites frequented by employees of the target company – a so-called \"water hole\" attack, just as lions stake out a watering hole for their prey. Elderwood infects these less-secure sites with malware that downloads to a computer that clicks on the site. After that, the group searches inside the network to which the infected computer is connected, finding and then downloading executives' e-mails and critical documents on company plans, decisions, acquisitions, and product designs.\n\nAttack analysis\nIn its blog posting, Google stated that some of its intellectual property had been stolen. It suggested that the attackers were interested in accessing Gmail accounts of Chinese dissidents. According to the Financial Times, two accounts used by Ai Weiwei had been attacked, their contents read and copied; his bank accounts were investigated by state security agents who claimed he was under investigation for \"unspecified suspected crimes\". However, the attackers were only able to view details on two accounts and those details were limited to things such as the subject line and the accounts' creation date.\n\nSecurity experts immediately noted the sophistication of the attack. Two days after the attack became public, McAfee reported that the attackers had exploited purported zero-day vulnerabilities (unfixed and previously unknown to the target system developers) in Internet Explorer and dubbed the attack \"Operation Aurora\". A week after the report by McAfee, Microsoft issued a fix for the issue, and admitted that they had known about the security hole used since September. Additional vulnerabilities were found in Perforce, the source code revision software used by Google to manage their source code.\n\nVeriSign's iDefense Labs claimed that the attacks were perpetrated by \"agents of the Chinese state or proxies thereof\".\n\nAccording to a diplomatic cable from the U.S. Embassy in Beijing, a Chinese source reported that the Chinese Politburo directed the intrusion into Google's computer systems. The cable suggested that the attack was part of a coordinated campaign executed by \"government operatives, public security experts and Internet outlaws recruited by the Chinese government.\" The report suggested that it was part of an ongoing campaign in which attackers have \"broken into American government computers and those of Western allies, the Dalai Lama and American businesses since 2002.\" According to The Guardian's reporting on the leak, the attacks were \"orchestrated by a senior member of the Politburo who typed his own name into the global version of the search engine and found articles criticising him personally.\"\n\nOnce a victim's system was compromised, a backdoor connection that masqueraded as an SSL connection made connections to command and control servers running in Illinois, Texas, and Taiwan, including machines that were running under stolen Rackspace customer accounts. The victim's machine then began exploring the protected corporate intranet that it was a part of, searching for other vulnerable systems as well as sources of intellectual property, specifically the contents of source code repositories.\n\nThe attacks were thought to have definitively ended on Jan 4 when the command and control servers were taken down, although it is not known at this point whether or not the attackers intentionally shut them down. However, the attacks were still occurring as of February 2010.\n\nResponse and aftermath\nThe German, Australian, and French governments publicly issued warnings to users of Internet Explorer after the attack, advising them to use alternative browsers at least until a fix for the security hole was made. The German, Australian, and French governments considered all versions of Internet Explorer vulnerable or potentially vulnerable.\n\nIn an advisory on January 14, 2010, Microsoft said that attackers targeting Google and other U.S. companies used software that exploits a hole in Internet Explorer. The vulnerability affects Internet Explorer versions 6, 7, and 8 on Windows 7, Vista, Windows XP, Server 2003, Server 2008 R2, as well as IE 6 Service Pack 1 on Windows 2000 Service Pack 4.\n\nThe Internet Explorer exploit code used in the attack has been released into the public domain, and has been incorporated into the Metasploit Framework penetration testing tool. A copy of the exploit was uploaded to Wepawet, a service for detecting and analyzing web-based malware operated by the computer security group at the University of California, Santa Barbara. \"The public release of the exploit code increases the possibility of widespread attacks using the Internet Explorer vulnerability,\" said George Kurtz, CTO of McAfee, of the attack. \"The now public computer code may help cybercriminals craft attacks that use the vulnerability to compromise Windows systems.\"\n\nSecurity company Websense said it identified \"limited public use\" of the unpatched IE vulnerability in drive-by attacks against users who strayed onto malicious Web sites. According to Websense, the attack code it spotted is the same as the exploit that went public last week.[clarification needed] \"Internet Explorer users currently face a real and present danger due to the public disclosure of the vulnerability and release of attack code, increasing the possibility of widespread attacks,\" said George Kurtz, chief technology officer of McAfee, in a blog update. Confirming this speculation, Websense Security Labs identified additional sites using the exploit on January 19. According to reports from Ahnlab, the second URL was spread through the Instant Messenger network Misslee Messenger, a popular IM client in South Korea.\n\nResearchers have created attack code that exploits the vulnerability in Internet Explorer 7 (IE7) and IE8—even when Microsoft's recommended defensive measure (Data Execution Prevention (DEP)) is turned on.[dubious – discuss] According to Dino Dai Zovi, a security vulnerability researcher, \"even the newest IE8 isn't safe from attack if it's running on Windows XP Service Pack 2 (SP2) or earlier, or on Windows Vista RTM (release to manufacturing), the version Microsoft shipped in January 2007.\"\n\nMicrosoft admitted that the security hole used had been known to them since September. Work on an update was prioritized and on Thursday, January 21, 2010, Microsoft released a security patch aiming to counter this weakness, the published exploits based on it and a number of other privately reported vulnerabilities. They did not state if any of the latter had been used or published by exploiters or whether these had any particular relation to the Aurora operation, but the entire cumulative update was termed critical for most versions of Windows, including Windows 7.\n\nSecurity researchers continued to investigate the attacks. HBGary, a security firm, released a report in which they claimed to have found some significant markers that might help identify the code developer. The firm also said that the code was Chinese language based but could not be specifically tied to any government entity.\n\nOn February 19, 2010, a security expert investigating the cyber-attack on Google, has claimed that the people behind the attack were also responsible for the cyber-attacks made on several Fortune 100 companies in the past one and a half years. They have also tracked the attack back to its point of origin, which seems to be two Chinese schools, Shanghai Jiao Tong University and Lanxiang Vocational School. As highlighted by The New York Times, both of these schools have ties with the Chinese search engine Baidu, a rival of Google China. Both Lanxiang Vocational and Jiaotong University have denied the allegation.\n\nIn March 2010, Symantec, which was helping investigate the attack for Google, identified Shaoxing as the source of 21.3% of all (12 billion) malicious emails sent throughout the world.\n\nGoogle retrospective\nOn October 3, 2022, Google on YouTube released a six-episode series covering the events that occurred during Operation Aurora, with commentary from insiders who dealt with the attack, though the series primary focus was to reassure the Google-using public that measures are in place to counter hacking attempts.",

        "answer": "Because, for entailment to hold as tagged in RTE, much world-knowledge is required and many missing hypotheses are omitted.",
        "evidence": "We find that our hypothesis is validated: RTE is not suitable as such to test a precise NLI system, because, for entailment to hold as tagged in RTE, much world-knowledge is required and many missing hypotheses are omitted.\nBy using a crowd of experts to repair the missing hypotheses, we have constructed a dataset of 150 precise entailment problems, based on text found in real-world corpora. Even though the dataset is on the small size, it is, to the best of our knowledge, the first of this kind.\nAn issue with the method that we used to construct our new dataset of entailment problems is that it is difficult to scale: it demands several minutes of scarce expert work per constructed problem. Our plan is to investigate the possibility to gamify the process, so that lots of people can participate in the construction of precise entailment problems, as a form of entertainment. We leave any detail to further work, but this would be an asymmetric game, where one one player tries construct watertight entailment problems, and the opposing player would try and refute such entailment problems (say, by giving counter-examples). Identifying the possible kind of mistakes, as we have done here, will help prompting the players about things to look for — in either of the possible roles.\nFinally we find it striking that many mistakes committed in RTE are falling for classical fallacies (appealing to authority accounts for more than a quarter of errors). Thus, we believe that while the entailment problems are useful for the construction of NLI systems, the added hypotheses (or moves taken in our hypothetical game) could be of interest to the linguistic community at large.\nWe find that our hypothesis is validated: RTE is not suitable as such to test a precise NLI system, because, for entailment to hold as tagged in RTE, much world-knowledge is required and many missing hypotheses are omitted.",

        "question": "Given this text, summarize the major events in Call of Duty: Modern Warfare 2 game development and release.",
        "evidence": "Call of Duty: Modern Warfare 2 is a 2009 first-person shooter game developed by Infinity Ward and published by Activision. It is the sixth installment in the Call of Duty series and the direct sequel to Call of Duty 4: Modern Warfare. It was released worldwide on November 10, 2009, for Microsoft Windows, the PlayStation 3, and Xbox 360. A separate version for the Nintendo DS, titled Modern Warfare: Mobilized, was also released on the same day. A version for macOS was developed by Aspyr and released in May 2014, and the Xbox 360 version was made backward compatible for the Xbox One in 2018.\n\nThe game's campaign follows Task Force 141, a multi-national special forces unit commanded by Captain Soap MacTavish as they hunt Vladimir Makarov, leader of the Russian Ultranationalist party, and U.S. Army Rangers from 1st Battalion/75th Ranger Regiment who are defending the Washington, D.C. area from a Russian invasion. The game's main playable characters are Sergeant Gary \"Roach\" Sanderson, of the 141, and Private James Ramirez, of the Army Rangers, with Captain MacTavish becoming playable later in the campaign. An expansive multiplayer mode is featured in the game, with several new features and modes that were not seen in its predecessor.\n\nDevelopment for the game began in 2008, when it was still known as Call of Duty 6. It uses the IW 4.0 engine, an improved version of Call of Duty 4's IW 3.0. Infinity Ward was inspired by real-life conflicts when developing the campaign mode. They initially tested the multiplayer mode by playing an in-house beta version of the game. Modern Warfare 2 was officially announced in February 2009. Teasing of the game began in March, with short trailers being released for the game and, eventually, a full reveal trailer. The multiplayer mode was revealed shortly after. Two downloadable content packs were released for it post-release, each containing five new multiplayer maps, with some being remastered maps from Call of Duty 4.\n\nModern Warfare 2 received universal acclaim, with praise for its campaign, multiplayer, and amount of content, although it received some criticism for its short length and a lack of innovation. Within 24 hours of release, the game sold approximately 4.7 million copies in North America and the United Kingdom. As of 2013, the game had sold 22.7 million copies. In addition to its release, a comic book series based on character Simon \"Ghost\" Riley was also produced, titled Modern Warfare 2: Ghost. Despite the game's success, it was subject to some controversies, with one surrounding a playable level that had the player carry out a terror attack on an airport. A sequel, Call of Duty: Modern Warfare 3, was released in 2011 and finishes the original Modern Warfare storyline. A remaster of the game's campaign, Call of Duty: Modern Warfare 2 Campaign Remastered, was released in March 2020 on the PlayStation 4 and on Microsoft Windows and Xbox One in April 2020.",

        "question": "Is the dataset challenging for both LMs and humans?",
        "answer": "Yes, it is.",
        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nWe find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.",

Zwift was not the first to introduce many of the virtual riding concepts, but the platform gained thousands of users during the covid-19 pandemic, and capitalised on the professional esports arena as well.\n\nZwift uses a more game-like graphical system, with multiple worlds that users can ride, with a monthly calendar changing the available worlds to ride it.  Zwit also has a comprehensive workout catalog.\n\nRouvy is a cycling platform that contains many of the features already mentioned, but it uses real world videos, with rider avatars superimposed over the top (Augmented Reality).

        "evidence": "In this section, we outline the technical details of ParityBot. The system consists of: 1) a Twitter listener that collects and classifies tweets directed at a known list of women candidates, and 2) a responder that sends out positivitweets when hateful tweets are detected.\nWe collect tweets from Twitter's real-time streaming API. The stream listener uses the open-source Python library Tweepy BIBREF8. The listener analyses tweets in real-time by firing an asynchronous tweet analysis and storage function for each English tweet mentioning one or more candidate usernames of interest. We limit the streaming to English as our text analysis models are trained on English language corpora. We do not track or store retweets to avoid biasing the analysis by counting the same content multiple times. Twitter data is collected and used in accordance with the acceptable terms of use BIBREF9.\nThe tweet analysis and storage function acts as follows: 1) parsing the tweet information to clean and extract the tweet text, 2) scoring the tweet using multiple text analysis models, and 3) storing the data in a database table. We clean tweet text with a variety of rules to ensure that the tweets are cleaned consistent with the expectations of the analysis models (see Appdx SECREF9).\nThe text analysis models classify a tweet by using, as features, the outputs from Perspective API from Jigsaw BIBREF10, HateSonar BIBREF11, and VADER sentiment models BIBREF12. Perspective API uses machine learning models to score the perceived impact a tweet might have BIBREF10. The outputs from these models (i.e. 17 from Perspective, 3 from HateSonar, and 4 from VADER) are combined into a single feature vector for each tweet (see Appdx SECREF10). No user features are included in the tweet analysis models. While these features may improve classification accuracy they can also lead to potential bias BIBREF13.\nWe measure the relative correlation of each feature with the hateful or not hateful labels. We found that Perspective API's TOXICITY probability was the most consistently predictive feature for classifying hateful tweets. Fig. FIGREF5 shows the relative frequencies of hateful and non-hateful tweets over TOXICITY scores. During both elections, we opted to use a single Perspective API feature to trigger sending positivitweets. Using the single TOXICITY feature is almost as predictive as using all features and a more complex model SECREF14. It was also simpler to implement and process tweets at scale. The TOXICITY feature is the only output from the Perspective API with transparent evaluation details summarized in a Model Card BIBREF14, BIBREF15.\nWe measure the relative correlation of each feature with the hateful or not hateful labels.

        "question": "What are the categories of these properties?",
        "answer": "The authors explicitly group the set of these properties into two categories: syntactic and social.",
        "evidence": "Research in social media analysis is recently seeing a surge in the number of research works applying representation learning models to solve high-level syntactico-semantic tasks such as sentiment analysis [1], semantic textual similarity computation [2], hashtag prediction [3] and so on. Though the performance of the representation learning models are better than the traditional models for all the tasks, little is known about the core properties of a tweet encoded within the representations. In a recent work, Hill et al. [4] perform a comparison of different sentence representation models by evaluating them for different high-level semantic tasks such as paraphrase identification, sentiment classification, question answering, document retrieval and so on. This type of coarse-grained analysis is opaque as it does not clearly reveal the kind of information encoded by the representations. Our work presented here constitutes the first step in opening the black-box of vector embeddings for social media posts, particularly tweets.\nEssentially we ask the following question: “What are the core properties encoded in the given tweet representation?”. We explicitly group the set of these properties into two categories: syntactic and social. Syntactic category includes properties such as tweet length, the order of words in it, the words themselves, slang words, hashtags and named entities in the tweet. On the other hand, social properties consist of `is reply', and `reply time'. We investigate the degree to which the tweet representations encode these properties. We assume that if we cannot train a classifier to predict a property based on its tweet representation, then this property is not encoded in this representation. For example, the model which preserves the tweet length should perform well in predicting the length given the representation generated from the model. Though these elementary property prediction tasks are not directly related to any downstream application, knowing that the model is good at modeling a particular property (e.g., the social properties) indicates that it could excel in correlated applications (e.g., user profiling task). In this work we perform an extensive evaluation of 9 unsupervised and 4 supervised tweet representation models, using 8 different properties. The most relevant work is that of Adi et al. [5], which investigates three sentence properties in comparing unsupervised sentence representation models such as average of words vectors and LSTM auto-encoders. We differ from their work in two ways: (1) While they focus on sentences, we focus on social media posts which opens up the challenge of considering multiple salient properties such as hashtags, named entities, conversations and so on. (2) While they work with only unsupervised representation-learning models, we investigate the traditional unsupervised methods (BOW, LDA), unsupervised representation learning methods (Siamese CBOW, Tweet2Vec), as well as supervised methods (CNN, BLSTM).\nOur main contributions are summarized below.\nThe paper is organized as follows. Sections 2 and 3 discuss the set of proposed elementary property prediction tasks and the models considered for this study respectively.

These studies analyse information based on manually labeled content, such as television transcripts BIBREF2 or tweets BIBREF4, BIBREF5. Restricting the analysis to manually labeled content ensures a high quality of annotations, but prohibits analysis from being extended to the full amount of available data. Another widely used method for classifying misleading content is to use distant annotations, for example to classify a tweet based on the domain of a URL that is shared by the tweet, or a hashtag that is contained in the tweet BIBREF6, BIBREF7, BIBREF8. Often, this approach treats content from uncredible sources as misleading (e.g. misinformation, disinformation or fake news). This methods enables researchers to scale up the number of observations without having to evaluate the fact value of each piece of content from low-quality sources. However, the approach fails to address an important issue: Not all content from uncredible sources is necessarily misleading or false and not all content from credible sources is true. As often emphasized in the propaganda literature, established media outlets too are vulnerable to state-driven disinformation campaigns, even if they are regarded as credible sources BIBREF9, BIBREF10, BIBREF11.\nIn order to scale annotations that go beyond metadata to larger datasets, Natural Language Processing (NLP) models can be used to automatically label text content.

Third, the prediction space of cross-lingual NLG is much larger than classification tasks, which makes knowledge transfer of decoders quite critical.",
        "evidence": "Learning natural language generation (NLG) models heavily relies on annotated training data. However, most available datasets are collected in a single language (typically English), which restricts deploying the applications to other languages. In this work, we aim at transferring the supervision of a monolingual NLG dataset to unseen languages, so that we can boost performance for the low-resource settings.\nVarious methods have been proposed over the years to learn universal cross-lingual word embeddings BIBREF0, BIBREF1, BIBREF2 or sentence encoders BIBREF3, BIBREF4, BIBREF5, which tries to encode multilingual texts into a single shared vector space. Despite achieving promising results on cross-lingual classification problems, cross-lingual pre-trained models purposed for NLG tasks remains relatively understudied.\nThe cross-lingual generation problem is challenging due to the following reasons. First, it requires the models to understand multilingual input texts, and generate multilingual target sequences. So both encoder and decoder should be pre-trained together. Second, the many-to-many nature of cross-lingual NLG increases language pairs with the square of the number of languages. Third, the prediction space of cross-lingual NLG is much larger than classification tasks, which makes the knowledge transfer of decoders quite critical.\nPrevious work mainly relies on machine translation (MT) systems to map texts to different languages. The first strand of research directly uses MT in a pipeline manner BIBREF6. For example, the input written in other languages is first translated to English, and fed into the NLG model that is trained by English data. Then the generated English text is translated back to the target language. Another strand of work employs MT to generate pseudo training data for other language pairs that are lack of annotations BIBREF7, BIBREF8. However, such methods have to use multiple MT systems, which renders them suffering from error propagation. Moreover, because the pipeline-based methods do not explicitly share the same parameter space across the languages, we can not directly transfer the task-specific supervision to other low-resource languages.\nIn this paper, we propose a cross-lingual pre-trained model (named as Xnlg) in order to transfer monolingual NLG supervision to other pre-trained languages by fine-tuning. Specifically, Xnlg shares the same sequence-to-sequence model across languages, and is pre-trained with both monolingual and cross-lingual objectives. The model not only learns to understand multilingual input, but also is able to generate specific languages by conditioning on the encoded semantics. Figure FIGREF2 demonstrates how to use Xnlg to perform cross-lingual transfer for downstream tasks. The proposed model enables us to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation. Besides, we explore several fine-tuning strategies to make a compromise between cross-lingual ability and task ability. In addition, we introduce two cross-lingual NLG datasets (i.e., question generation, and abstractive summarization) for evaluation, which includes three languages, namely English, Chinese, and French. Experimental results on the NLG tasks show that Xnlg achieves competitive performance compared with the machine-translation-based pipeline model in zero-shot cross-lingual settings.\nThe cross-lingual generation problem is challenging due to the following reasons. First, it requires the models to understand multilingual input texts, and generate multilingual target sequences. So both the encoder and the decoder should be pre-trained together.

        "answer": "No.",
        "evidence": "Experiment 1 directly tested the hypothesis that speakers increase their specificity in contexts with asymmetry in visual access. We found that speakers are not only context-sensitive in choosing referring expressions that distinguish target from distractors in a shared context, but are occlusion-sensitive, adaptively compensating for uncertainty. Critically, this resulted in systematic differences in behavior across the occlusion conditions that are difficult to explain under an egocentric theory: in the presence of occlusions, speakers were spontaneously willing to spend additional time and keystrokes to give further information beyond what they produce in the corresponding unoccluded contexts, even though that information is equally redundant given the visible objects in their display.\nThese results strongly suggest that the speaker's informativity influences listener accuracy. In support of this hypothesis, we found a strong negative correlation between informativity and error rates across items and conditions: listeners make fewer errors when utterances are a better fit for the target relative to the distractor ( $\\rho = -0.81$ , bootstrapped 95% CI $= [-0.9, -0.7]$ ; Fig. 6 B). This result suggests that listener behavior is driven by an expectation of speaker informativity: listeners interpret utterances proportionally to how well they fit objects in context.\nAre human adults expert mind-readers, or fundamentally egocentric? The longstanding debate over the role of theory of mind in communication has largely centered around whether listeners (or speakers) with private information consider their partner's perspective BIBREF30 , BIBREF16 . Our work presents a more nuanced picture of how a speaker and a listener use theory of mind to modulate their pragmatic expectations. The Gricean cooperative principle emphasizes a natural division of labor in how the joint effort of being cooperative is shared BIBREF4 , BIBREF60 . It can be asymmetric when one partner is expected to, and able to, take on more complex reasoning than the other, in the form of visual perspective-taking, pragmatic inference, or avoiding further exchanges of clarification and repair. One such case is when the speaker has uncertainty over what the listener can see, as in the director-matcher task. Our Rational Speech Act (RSA) formalization of cooperative reasoning in this context predicts that speakers (directors) naturally increase the informativity of their referring expressions to hedge against the increased risk of misunderstanding; Exp. 1 presents direct evidence in support of this hypothesis.\nImportantly, when the director (speaker) is expected to be appropriately informative, communication can be successful even when the matcher (listener) does not reciprocate the effort. If visual perspective-taking is effortful and cognitively demanding BIBREF39 , the matcher will actually minimize joint effort by not taking the director's visual perspective. This suggests a less egocentric explanation of when and why listeners neglect the speaker's visual perspective; they do so when they expect the speaker to disambiguate referents sufficiently. While adaptive in most natural communicative contexts, such neglect might backfire and lead to errors when the speaker (inexplicably) violates this expectation. From this point of view, the “failure” of listener theory of mind in these tasks is not really a failure; instead, it suggests that both speakers and listeners may use theory of mind to know when (and how much) they should expect others to be cooperative and informative, and subsequently allocate their resources accordingly BIBREF36 . Exp. 2 is consistent with this hypothesis; when directors used underinformative scripted instructions (taken from prior work), listeners made significantly more errors than when speakers were allowed to provide referring expressions at their natural level of informativity, and speaker informativeness strongly modulated listener error rates.\nExperiment 1 directly tested the hypothesis that speakers increase their specificity in contexts with asymmetry in visual access. We found that speakers are not only context-sensitive in choosing referring expressions that distinguish target from distractors in a shared context, but are occlusion-sensitive, adaptively compensating for uncertainty.\nThese results strongly suggest that the speaker's informativity influences listener accuracy. In support of this hypothesis, we found a strong negative correlation between informativity and error rates across items and conditions: listeners make fewer errors when utterances are a better fit for the target relative to the distractor ( $\\rho = -0.81$ , bootstrapped 95% CI $= [-0.9, -0.7]$ ; Fig. 6 B). This result suggests that listener behavior is driven by an expectation of speaker informativity: listeners interpret utterances proportionally to how well they fit objects in context.\nOur Rational Speech Act (RSA) formalization of cooperative reasoning in this context predicts that speakers (directors) naturally increase the informativity of their referring expressions to hedge against the increased risk of misunderstanding; Exp. 1 presents direct evidence in support of this hypothesis.\nExp. 2 is consistent with this hypothesis; when directors used underinformative scripted instructions (taken from prior work), listeners made significantly more errors than when speakers were allowed to provide referring expressions at their natural level of informativity, and speaker informativeness strongly modulated listener error rates.",

        "question": "What experiments did the authors do to verify the framework proposed by Tu et al.?",
        "answer": "They experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoderreconstructor.",
        "evidence": "Recently, neural machine translation (NMT) has gained popularity in the field of machine translation. The conventional encoder-decoder NMT proposed by Cho2014 uses two recurrent neural networks (RNN): one is an encoder, which encodes a source sequence into a fixed-length vector, and the other is a decoder, which decodes the vector into a target sequence. A newly proposed attention-based NMT by DzmitryBahdana2014 can predict output words using the weights of each hidden state of the encoder by the attention mechanism, improving the adequacy of translation.\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu2016 argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated. This is due to the fact that NMT can not completely convert the information from the source sentence to the target sentence. Mi2016a and Feng2016 pointed out that NMT lacks the notion of coverage vector in phrase-based statistical machine translation (PBSMT), so unless otherwise specified, there is no way to prevent missing translations.\nAnother problem in NMT is an objective function. NMT is optimized by cross-entropy; therefore, it does not directly maximize the translation accuracy. Shen2016 pointed out that optimization by cross-entropy is not appropriate and proposed a method of optimization based on a translation accuracy score, such as expected BLEU, which led to improvement of translation accuracy. However, BLEU is an evaluation metric based on n-gram precision; therefore, repetition of some words may be present in the translation even though the BLEU score is improved.\nTo address to problem of repeating and missing words in the translation, tu2016neural introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences. In their method, after training the forward translation in a manner similar to the conventional attention-based NMT, they train a back-translation model from the hidden state of the decoder into the source sequence by a new decoder to enforce agreement between source and target sentences.\nIn order to confirm the language independence of the framework, we experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoder-reconstructor. Our experiments show that their method offers significant improvement in BLEU scores and alleviates the problem of repeating and missing words in the translation on English-Japanese translation task, though the difference is not significant on Japanese-English translation task.\nIn addition, we jointly train a model of forward translation and back-translation without pre-training, and then evaluate this model. As a result, the encoder-decoder-reconstructor can not be trained well without pre-training, so it proves that we have to train the forward translation model in a manner similar to the conventional attention-based NMT as pre-training.\nThe main contributions of this paper are as follows:\nIn order to confirm the language independence of the framework, we experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoderreconstructor.",

        "question": "What applications are Overton used in?",
        "answer": "Near-real-time and backend production applications.",
        "evidence": "In the life cycle of many production machine-learning applications, maintaining and improving deployed models is the dominant factor in their total cost and effectiveness–much greater than the cost of de novo model construction. Yet, there is little tooling for model life-cycle support. For such applications, a key task for supporting engineers is to improve and maintain the quality in the face of changes to the input distribution and new production features. This work describes a new style of data management system called Overton that provides abstractions to support the model life cycle by helping build models, manage supervision, and monitor application quality.\nOverton is used in both near-real-time and backend production applications. However, for concreteness, our running example is a product that answers factoid queries, such as “how tall is the president of the united states?” In our experience, the engineers who maintain such machine learning products face several challenges on which they spend the bulk of their time.\nFine-grained Quality Monitoring While overall improvements to quality scores are important, often the week-to-week battle is improving fine-grained quality for important subsets of the input data. An individual subset may be rare but are nonetheless important, e.g., 0.1% of queries may correspond to a product feature that appears in an advertisement and so has an outsized importance. Traditional machine learning approaches effectively optimize for aggregate quality. As hundreds of such subsets are common in production applications, this presents data management and modeling challenges. An ideal system would monitor these subsets and provide tools to improve these subsets while maintaining overall quality.\nSupport for Multi-component Pipelines Even simple machine learning products comprise myriad individual tasks. Answering even a simple factoid query, such as “how tall is the president of the united states?” requires tackling many tasks including (1) find the named entities (`united states', and `president'), (2) find the database ids for named entities, (3) find the intent of the question, e.g., the height of the topic entity, (4) determine the topic entity, e.g., neither president nor united states, but the person Donald J. Trump, who is not explicitly mentioned, and (5) decide the appropriate UI to render it on a particular device. Any of these tasks can go wrong. Traditionally, systems are constructed as pipelines, and so determining which task is the culprit is challenging.\nUpdating Supervision When new features are created or quality bugs are identified, engineers provide additional supervision. Traditionally, supervision is provided by annotators (of varying skill levels), but increasingly programmatic supervision is the dominant form of supervision BIBREF0, BIBREF1, which includes labeling, data augmentation, and creating synthetic data. For both privacy and cost reasons, many applications are constructed using programmatic supervision as a primary source. An ideal system can accept supervision at multiple granularities and resolve conflicting supervision for those tasks.\nThere are other desiderata for such a system, but the commodity machine learning stack has evolved to support them: building deployment models, hyperparameter tuning, and simple model search are now well supported by commodity packages including TensorFlow, containers, and (private or public) cloud infrastructure. By combining these new systems, Overton is able to automate many of the traditional modeling choices, including deep learning architecture, its hyperparameters, and even which embeddings are used.\nOverton provides the engineer with abstractions that allow them to build, maintain, and monitor their application by manipulating data files–not custom code. Inspired by relational systems, supervision (data) is managed separately from the model (schema). Akin to traditional logical independence, Overton's schema provides model independence: serving code does not change even when inputs, parameters, or resources of the model change. The schema changes very infrequently–many production services have not updated their schema in over a year.\nOverton takes as input a schema whose design goal is to support rich applications from modeling to automatic deployment. In more detail, the schema has two elements: (1) data payloads similar to a relational schema, which describe the input data, and (2) model tasks, which describe the tasks that need to be accomplished. The schema defines the input, output, and coarse-grained data flow of a deep learning model. Informally, the schema defines what the model computes but not how the model computes it: Overton does not prescribe architectural details of the underlying model (e.g., Overton is free to embed sentences using an LSTM or a Transformer) or hyperparameters, like hidden state size. Additionally, sources of supervision are described as data–not in the schema–so they are free to rapidly evolve.\nAs shown in Figure FIGREF7, given a schema and a data file, Overton is responsible to instantiate and train a model, combine supervision, select the model's hyperparameters, and produce a production-ready binary. Overton compiles the schema into a (parameterized) TensorFlow or PyTorch program, and performs an architecture and hyperparameter search. A benefit of this compilation approach is that Overton can use standard toolkits to monitor training (TensorBoard equivalents) and to meet service-level agreements (Profilers). The models and metadata are written to an S3-like data store that is accessible from the production infrastructure. This has enabled model retraining and deployment to be nearly automatic, allowing teams to ship products more quickly.\nIn retrospect, the following three choices of Overton were the most important in meeting the above challenges.\n(1) Code-free Deep Learning In Overton-based systems, engineers focus exclusively on fine-grained monitoring of their application quality and improving supervision–not tweaking deep learning models. An Overton engineer does not write any deep learning code in frameworks like TensorFlow. To support application quality improvement, we use a technique, called model slicing BIBREF3. The main idea is to allow the developer to identify fine-grained subsets of the input that are important to the product, e.g., queries about nutrition or queries that require sophisticated disambiguation. The system uses developer-defined slices as a guide to increase representation capacity. Using this recently developed technique led to state-of-the-art results on natural language benchmarks including GLUE and SuperGLUE BIBREF4.\n(2) Multitask Learning Overton was built to natively support multitask learning BIBREF5, BIBREF6, BIBREF7 so that all model tasks are concurrently predicted. A key benefit is that Overton can accept supervision at whatever granularity (for whatever task) is available. Overton models often perform ancillary tasks like part-of-speech tagging or typing. Intuitively, if a representation has captured the semantics of a query, then it should reliably perform these ancillary tasks. Typically, ancillary tasks are also chosen either to be inexpensive to supervise. Ancillary task also allow developers to gain confidence in the model's predictions and have proved to be helpful for aids for debugging errors.\n(3) Weak Supervision Applications have access to supervision of varying quality and combining this contradictory and incomplete supervision is a major challenge. Overton uses techniques from Snorkel BIBREF1 and Google's Snorkel DryBell BIBREF0, which have studied how to combine supervision in theory and in software. Here, we describe two novel observations from building production applications: (1) we describe the shift to applications which are constructed almost entirely with weakly supervised data due to cost, privacy, and cold-start issues, and (2) we observe that weak supervision may obviate the need for popular methods like transfer learning from massive pretrained models, e.g., BERT BIBREF8–on some production workloads, which suggests that a deeper trade-off study may be illuminating.\nIn summary, Overton represents a first-of-its kind machine-learning lifecycle management system that has a focus on monitoring and improving application quality. A key idea is to separate the model and data, which is enabled by a code-free approach to deep learning. Overton repurposes ideas from the database community and the machine learning community to help engineers in supporting the lifecycle of machine learning toolkits. This design is informed and refined from use in production systems for over a year in multiple machine-learned products.\nOverton is used in both near-real-time and backend production applications.",

(See below for further discussion on the reported missing hypotheses.) Thus crunching the numbers, we see that more that half of the responses express some doubt about entailment. Remember that all problems were marked as “yes” by the creators of the RTE3 testsuite — we find here that one average, one expert in two is likely to cast a doubt over this “yes”.\nHowever, each problem was classified by three experts. The histogram below shows the distribution of number of experts casting doubt on entailment, over all problems.\n[ybar interval, ymax=0.5,ymin=0, minor y tick num = 0] coordinates (0, 0.26666666666666666) (1, 0.17333333333333334) (2, 0.3466666666666667) (3, 0.21333333333333335) (4,0) ;\nUnfortunately we can only draw preliminary conclusions, due to the limited number of respondents for each problem. However, we can make the following observations:\nWe find this level of agreement indicative of a good level of reliability. Additionally, with three experts per problem, we are very likely to discover most missing hypotheses and incorrect entailments.\nIn our compilation of answers, we have marked 42 problems as straight “No”, 64 as “Yes” with missing implicit hypotheses and “44” as plain “Yes”. This means that, we expect, in our opinion, 28% of problems to be incorrectly labeled in RTE3 even assuming reasonable world knowledge. An additional 42% of problems require additional (yet reasonable to assume) hypotheses for entailment to hold formally, as prescribed by RTE3. This leaves only 30% of problems to acceptable as such. The reason that the amount of doubt is larger than in the average numbers quoted above is that, for many problems, certain missing hypotheses and/or error were not detected by a majority experts, but, after careful inspection, we judge that the minority report is justified.\nWe have additionally tagged each missing hypothesis according to the following classification:\nWe have additionally tagged each missing hypothesis according to the following classification: 1.

        "answer": "Woke is a general political term used to group a set of similar ideologies in an attempt to characterize the political motivations typically ascribed to the far left. Although many definitions of woke exist, these definitions run along a few common threads. Woke is typically used to describe the ideals underpinning what is known as equality of outcome. This is to be contrasted with the opposing political forces who support equality of opportunity.\n\nThose who engage in wokeness more often than not cite disparities as evidence of systemic biases or expressions of racism, sexism, classism, genderism, agism and other prejudices. A common example would be that females are disproportionately represented in elementary school teaching whereas males are disproportionately represented in railroad construction. Woke politics would lead us to believe that this is evidence of sexism: women and men are socialized differently so they are pushed into different positions by institutions. Woke opponents would lead us to believe this is evidence of inate preferences different between the sexes: males are generally stronger than females, so men are more suited to performing heavy labor.\n\nWokeness is controversial because its opponents do not believe disparity is evidence of bias. Disparities can exist due to natural or cultural differences, neither of which can be governed out of existence. The opponents of woke ideology also proclaim that it ignores the root cause of problems which plague society. If one's analysis stops at disparity and from disparity an answer is assumed, one can miss the nuances present in a situation. A common unavoidable disparity cited is that 100% of births are to females, but this is not sexism. Analysis past disparity is required to prove or disprove systemic or individual bias.",

Eyes also fall into two groups on the basis of their photoreceptor's cellular construction, with the photoreceptor cells either being cilliated (as in the vertebrates) or rhabdomeric.

This paper presents the contributions from the Cambridge University Engineering Department to the latest GEC competition at the BEA 2019 workshop.\nWe submitted systems to two different tracks. The low-resource track did not permit the use of parallel training data except a small development set with around 4K sentence pairs. For our low-resource system we extended our prior work on finite state transducer based GEC BIBREF3 to handle new error types such as punctuation errors as well as insertions and deletions of a small number of frequent words. For the restricted track, the organizers provided 1.2M pairs (560K without identity mappings) of corrected and uncorrected sentences. Our goal on the restricted track was to explore the potential of purely neural models for grammatical error correction. We confirm the results of BIBREF4 and report substantial gains by applying back-translation BIBREF5 to GEC – a data augmentation technique common in machine translation.

        "answer": "over 8%.",
        "evidence": "Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the mid-brain producing several motor and non-motor impairments in the patients BIBREF0. Motor symptoms include among others, bradykinesia, rigidity, resting tremor, micrographia, and different speech impairments. The speech impairments observed in PD patients are typically grouped as hypokinetic dysarthria, and include symptoms such as vocal folds rigidity, bradykinesia, and reduced control of muscles and limbs involved in the speech production. The effects of dysarthria in the speech of PD patients include increased acoustic noise, reduced intensity, harsh and breathy voice quality, increased voice nasality, monopitch, monoludness, speech rate disturbances, imprecise articulation of consonants BIBREF1, and involuntary introduction of pauses BIBREF2. Clinical observations in the speech of patients can be objectively and automatically measured by using computer aided methods supported in signal processing and pattern recognition with the aim to address two main aspects: (1) to support the diagnosis of the disease by classifying healthy control (HC) subjects and patients, and (2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.\nMost of the studies in the literature to classify PD from speech are based on computing hand-crafted features and using classifiers such as support vector machines (SVMs) or K-nearest neighbors (KNN). For instance, in BIBREF3, the authors computed features related to perturbations of the fundamental frequency and amplitude of the speech signal to classify utterances from 20 PD patients and 20 HC subjects, Turkish speakers. Classifiers based on KNN and SVMs were considered, and accuracies of up to 75% were reported. Later, in BIBREF4 the authors proposed a phonation analysis based on several time frequency representations to assess tremor in the speech of PD patients. The extracted features were based on energy and entropy computed from time frequency representations. Several classifiers were used, including Gaussian mixture models (GMMs) and SVMs. Accuracies of up to 77% were reported in utterances of the PC-GITA database BIBREF5, formed with utterances from 50 PD patients and 50 HC subjects, Colombian Spanish native speakers. The authors from BIBREF6 computed features to model different articulation deficits in PD such as vowel quality, coordination of laryngeal and supra-laryngeal activity, precision of consonant articulation, tongue movement, occlusion weakening, and speech timing. The authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier. Additional articulation features were proposed in BIBREF7, where the authors modeled the difficulty of PD patients to start/stop the vocal fold vibration in continuous speech. The model was based on the energy content in the transitions between unvoiced and voiced segments. The authors classified PD patients and HC speakers with speech recordings in three different languages (Spanish, German, and Czech), and reported accuracies ranging from 80% to 94% depending on the language; however, the results were optimistic, since the hyper-parameters of the classifier were optimized based on the accuracy on the test set. Another articulation model was proposed in BIBREF8. The authors considered a forced alignment strategy to segment the different phonetic units in the speech utterances. The phonemes were segmented and grouped to train different GMMs. The classification was performed based on a threshold of the difference between the posterior probabilities from the models created for HC subjects and PD patients. The model was tested with Colombian Spanish utterances from the PC-GITA database BIBREF5 and with the Czech data from BIBREF9. The authors reported accuracies of up to 81% for the Spanish data, and of up to 94% for the Czech data.\nIn addition to the hand-crafted feature extraction models, there is a growing interest in the research community to consider deep learning models in the assessment of the speech of PD patients BIBREF10, BIBREF11, BIBREF12. Deep learning methods have the potential to extract more abstract and robust features than those manually computed. These features could help to improve the accuracy of different models to classify pathological speech, such as PD BIBREF13. A deep learning based articulation model was proposed in BIBREF11 to model the difficulties of the patients to stop/start the vibration of the vocal folds. Transitions between voiced and unvoiced segments were modeled with time-frequency representations and convolutional neural networks (CNNs). The authors considered speech recordings of PD patients and HC speakers in three languages: Spanish, German, and Czech, and reported accuracies ranging from 70% to 89%, depending on the language. However, in a language independent scenario, i.e., training the CNN with utterances from one language and testing with the remaining two, the results were not satisfactory (accuracy$<60\\%$).\nThe classification of PD from speech in different languages has to be carefully conducted to avoid bias towards the linguistic content present in each language. For instance, Czech and German languages are richer than Spanish language in terms of consonant production, which may cause that it is easier to produce consonant sounds by Czech PD patients than by Spanish PD patients. Despite these language dependent issues, the results in the classification of PD in different languages could be improved using a transfer learning strategy among languages, i.e., to train a base model with utterances from one language, and then, to perform a fine-tuning of the weights with utterances from the target language BIBREF14. Similar approaches based on transfer learning have been recently considered to classify PD using handwriting BIBREF15. In the present study, we propose a methodology to classify PD via a transfer learning strategy with the aim to improve the accuracy in different languages. CNNs trained with utterances from one language are used to initialize a model to classify speech utterances from PD patients in a different language. The models are evaluated with speech utterances in Spanish, German, and Czech languages. The results suggest that the use of a transfer learning strategy improved the accuracy of the models over 8% with respect to those obtained when the model is trained only with utterance from the target language.\nThe results suggest that the use of a transfer learning strategy improved the accuracy of the models over 8% with respect to those obtained when the model is trained only with utterance from the target language.",

        "answer": "The normalization of deviance was a term coined by the sociologist Diane Vaughan who participated in the review of the Challenger disaster.  It was later the the subject of a number of public talks by astronaut Mike Mullane.  The theory is essentially that when we accept deviations from an expected standard, the deviation becomes the standard.  In the Challenger disaster, engineers kept noticing rubber o-rings that came back from tests in an out of tolerance state.  Because there were no dramatic failures during the tests, the engineers adjusted the standard for the o-rings to absorb these abnormalities.  Unfortunately, by normalizing deviance from the expected standard, it led to an o-ring failing during the Challenger launch, and the Challenger shuttle disintegrated in flight.  The normalization of deviance is an important pitfall to avoid when running any organization, but especially those which put its members in high risk situations, such as space travel.  To avoid it, you must remember, or learn, how and why certain standards were developed and adhere to them, even when pressures are high.",

        "answer": "To capture and imitate a behavior when human completes writing a description of paired information.",
        "evidence": "Intuitively, when a human writes a description from a table she keeps track of information at two levels. At the macro level, it is important to decide which is the appropriate field to attend to next and at a micro level (i.e., within a field) it is important to know which values to attend to next. To capture this behavior, we use a bifocal attention mechanism as described below.\nMacro Attention: Consider the INLINEFORM0 -th field INLINEFORM1 which has values INLINEFORM2 . Let INLINEFORM3 be the representation of this field in the infobox. This representation can either be (i) the word embedding of the field name or (ii) some function INLINEFORM4 of the values in the field or (iii) a concatenation of (i) and (ii). The function INLINEFORM5 could simply be the sum or average of the embeddings of the values in the field. Alternately, this function could be a GRU (or LSTM) which treats these values within a field as a sequence and computes the field representation as the final representation of this sequence (i.e., the representation of the last time-step). We found that bidirectional GRU is a better choice for INLINEFORM6 and concatenating the embedding of the field name with this GRU representation works best. Further, using a bidirectional GRU cell to take contextual information from neighboring fields also helps (these are the orange colored cells in the top-left block in Figure FIGREF3 with macro attention). Given these representations INLINEFORM7 for all the INLINEFORM8 fields we compute an attention over the fields (macro level). DISPLAYFORM0 \nwhere INLINEFORM0 is the state of the decoder at time step INLINEFORM1 . INLINEFORM2 and INLINEFORM3 are parameters, INLINEFORM4 is the total number of fields in the input, INLINEFORM5 is the macro (field level) context vector at the INLINEFORM6 -th time step of the decoder.\nMicro Attention: Let INLINEFORM0 be the representation of the INLINEFORM1 -th value in a given field. This representation could again either be (i) simply the embedding of this value (ii) or a contextual representation computed using a function INLINEFORM2 which also considers the other values in the field. For example, if INLINEFORM3 are the values in a field then these values can be treated as a sequence and the representation of the INLINEFORM4 -th value can be computed using a bidirectional GRU over this sequence. Once again, we found that using a bi-GRU works better then simply using the embedding of the value. Once we have such a representation computed for all values across all the fields, we compute the attention over these values (micro level) as shown below : DISPLAYFORM0 \n where INLINEFORM0 is the state of the decoder at time step INLINEFORM1 . INLINEFORM2 and INLINEFORM3 are parameters, INLINEFORM4 is the total number of values across all the fields.\nFused Attention: Intuitively, the attention weights assigned to a field should have an influence on all the values belonging to the particular field. To ensure this, we reweigh the micro level attention weights based on the corresponding macro level attention weights. In other words, we fuse the attention weights at the two levels as: DISPLAYFORM0 \n where INLINEFORM0 is the field corresponding to the INLINEFORM1 -th value, INLINEFORM2 is the macro level context vector.\nIntuitively, when a human writes a description from a table she keeps track of information at two levels. At the macro level, it is important to decide which is the appropriate field to attend to next and at a micro level (i.e., within a field) it is important to know which values to attend to next.

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nFurthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets.",

It is mostly distributed into two distinct domains, i.e., Abstractive Summarization and Extractive Summarization. Abstractive summarization( Dejong et al. ,1978) involves models to deduce the crux of the document. It then presents a summary consisting of words and phrases that were not there in the actual document, sometimes even paraphrasing BIBREF1 . A state of art method proposed by Wenyuan Zeng BIBREF2 produces such summaries with length restricted to 75. There have been many recent developments that produce optimal results, but it is still in a developing phase. It highly relies on natural language processing techniques, which is still evolving to match human standards. These shortcomings make abstractive summarization highly domain selective. As a result, their application is skewed to the areas where NLP techniques have been superlative. Extractive Summarization, on the other hand, uses different methods to identify the most informative/dominant sentences through the text, and then present the results, ranking them accordingly. In this paper, we have proposed two novel stand-alone summarization methods.The first method is based on Glove Model BIBREF3 ,and other is based on Facebook's InferSent BIBREF4 .

        "answer": "Explainable inference tasks.",
        "evidence": "Question answering (QA) is a high-level natural language processing task that requires automatically providing answers to natural language questions. The approaches used to construct QA solvers vary depending on the questions and domain, from inference methods that attempt to construct answers from semantic, syntactic, or logical decompositions, to retrieval methods that work to identify passages of text likely to contain the answer in large corpora using statistical methods. Because of the difficulty of this task, overall QA task performance tends to be low, with generally between 20% and 80% of natural (non-artificially generated) questions answered correctly, depending on the questions, the domain, and the knowledge and inference requirements.\nStandardized science exams have recently been proposed as a challenge task for question answering BIBREF0 , as these questions have very challenging knowledge and inference requirements BIBREF1 , BIBREF2 , but are expressed in simple-enough language that the linguistic challenges are likely surmountable in the near-term. They also provide a standardized comparison of modern inference techniques against human performance, with individual QA solvers generally answering between 40% to 50% of multiple choice science questions correctly BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , and top-performing ensemble models nearly reaching a passing grade of 60% on middle school (8th grade) science exams during a recent worldwide competition of 780 teams sponsored by the Allen Institute for AI BIBREF8 .\nOne of the central shortcomings of question answering models is that while solvers are steadily increasing the proportion of questions they answer correctly, most solvers generally lack the capacity to provide human-readable explanations or justifications for why those answers are correct. This “explainable inference” task is seen as a limitation of current machine learning models in general (e.g. Ribeiro et al., Ribeiro2016), but is critical for domains such as science or medicine where user trust and detecting potentially costly errors are important. More than this, evidence from the cognitive and pedagogy literature suggests that explanations (when tutoring others) and self-explanations (when engaged in self-directed learning) are an important aspect of learning, helping humans better generalize the knowledge they have learned BIBREF9 , BIBREF10 , BIBREF11 . This suggests that explainable methods of inference may not only be desirable for users, but may be a requirement for automated systems to have human-like generalization and inference capabilities.\nBuilding QA solvers that generate explanations for their answers is a challenging task, requiring a number of inference capacities. Central among these is the idea of information aggregation, or the idea that explanations for a given question are rarely found in a contiguous passage of text, and as such inference methods must generally assemble many separate pieces of knowledge from different sources in order to arrive at a correct answer. Previous estimates BIBREF2 suggest elementary science questions require an average of 4 pieces of knowledge to answer and explain those answers (here our analysis suggests this is closer to 6), but inference methods tend to have difficulty aggregating more than 2 pieces of knowledge from free-text together due to the semantic or contextual “drift” associated with this aggregation BIBREF12 . Because of the difficulty in assembling training data for the information aggregation task, some have approached explanation generation as a distant supervision problem, with explanation quality modelled as a latent variable BIBREF7 , BIBREF13 . While these techniques have had some success in constructing short explanations, semantic drift likely limits the viability of this technique for explanations requiring more than two pieces of information to be aggregated.\nTo address this, here we construct a large corpus of explanation graphs (see Figure 1 ) to serve as training data for explainable inference tasks. The contributions of this work are are:\nWhile these techniques have had some success in constructing short explanations, semantic drift likely limits the viability of this technique for explanations requiring more than two pieces of information to be aggregated.

        "evidence": "Apart from fission induced by a neutron, harnessed and exploited by humans, a natural form of spontaneous radioactive decay (not requiring a neutron) is also referred to as fission, and occurs especially in very high-mass-number isotopes. Spontaneous fission was discovered in 1940 by Flyorov, Petrzhak, and Kurchatov in Moscow, in an experiment intended to confirm that, without bombardment by neutrons, the fission rate of uranium was negligible, as predicted by Niels Bohr; it was not negligible.\n\nThe unpredictable composition of the products (which vary in a broad probabilistic and somewhat chaotic manner) distinguishes fission from purely quantum tunneling processes such as proton emission, alpha decay, and cluster decay, which give the same products each time. Nuclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when struck by fission neutrons, and in turn emit neutrons when they break apart. This makes a self-sustaining nuclear chain reaction possible, releasing energy at a controlled rate in a nuclear reactor or at a very rapid, uncontrolled rate in a nuclear weapon.\n\nThe amount of free energy contained in nuclear fuel is millions of times the amount of free energy contained in a similar mass of chemical fuel such as gasoline, making nuclear fission a very dense source of energy. The products of nuclear fission, however, are on average far more radioactive than the heavy elements which are normally fissioned as fuel, and remain so for significant amounts of time, giving rise to a nuclear waste problem. However, the seven long-lived fission products make up only a small fraction of fission products. Neutron absorption which does not lead to fission produces Plutonium (from 238\nU) and minor actinides (from both 235\nU and 238\nU) whose radiotoxicity is far higher than that of the long lived fission products. Concerns over nuclear waste accumulation and the destructive potential of nuclear weapons are a counterbalance to the peaceful desire to use fission as an energy source. The thorium fuel cycle produces virtually no plutonium and much less minor actinides, but 232\nU - or rather its decay products - are a major gamma ray emitter. All actinides are fertile or fissile and fast breeder reactors can fission them all albeit only in certain configurations. Nuclear reprocessing aims to recover usable material from spent nuclear fuel to both enable uranium (and thorium) supplies to last longer and to reduce the amount of \"waste\". The industry term for a process that fissions all or nearly all actinides is a \"closed fuel cycle\".",

        "answer": "Thank you for raising the concern. We would like to clarify that our methods are not a simple combination of BYOL and FedAvg. Although ICCV 2021 paper [1] proposes a new method (FedU) based on BYOL, they do not shed light on why BYOL works best. Since SSL methods are evolving rapidly and new methods (like SimSiam [2], MoCoV2, SimCLR) are emerging, it is crucial to understand the fundamental components of FedSSL. In this paper, we first introduce a generalized FedSSL framework that embraces existing SSL methods and has flexibility catering to future methods. Then, we took an investigative approach to deeply investigate the fundamental components of FedSSL to build up intuitions and practical guidelines for the generic FedSSL framework. Based on these insights, we propose a new model update approach, FedEMA, which improves the performance substantially. We have revised the Related Work section with these discussions. Besides, we would like to point out that FedEMA outperforms [1], as shown in Table 3, 4, 5, and 7 in the manuscript.\n[1] Collaborative unsupervised visual representation learning from decentralized data.

        "evidence": "Self-supervised Learning In computer vision, self-supervised learning (SSL) aims to learn visual representations without any labels. Discriminative SSL methods facilitate learning with proxy tasks. Among them, contrastive learning has become a promising principle. It uses Siamese networks to minimize the similarity of two augmented views (positive pairs) and maximize the similarity of two different images (negative pairs). These methods are either contrastive or non-contrastive ones: contrastive SSL methods require negative pairs to prevent training collapse; non-contrastive SSL methods are generally more efficient as they maintain remarkable performances using only positive pairs. However, these methods do not perform well on decentralized non-IID data. We analyze their similarities and variances and propose a generalized FedSSL framework.\nFederated Learning Federated learning (FL) is a distributed training technique for learning from decentralized parties without transmitting raw data to a central server. Among many studies that address the non-IID data challenge, Personalized FL (PFL) aims to learn personalized models for clients. Although some PFL methods interpolate global and local models, our proposed FedEMA differ in the motivation, application scenario, and measurement of the decay rate. Besides, the majority of existing works only consider supervised learning where clients have fully labeled data. Although recent works propose federated semi-supervised learning or federated domain adaptation, they still need labels in either the server or clients. This paper focuses on purely unlabeled decentralized data.\nFederated Unsupervised Learning Learning representations from unlabeled decentralized data while preserving data privacy is still a nascent field. Federated unsupervised representation learning is first proposed by van Berlo et al. (2020) based on autoencoder, but it neglects the non-IID data challenge. Zhang et al. (2020a) address the non-IID issue with potential privacy risk for sharing features. Although Zhuang et al. (2020) address the issue based on BYOL as our FedEMA, they do not shed light on why BYOL works best.

Since the solution to the sub-problems of the upper-level objective has been well-explored in recent PFL methods, we hereby mainly focus on the inner-level problem. We alternately update the generalized models Ω K and the cluster indicator C K to obtain the optimal generalized models. We view the personalized models, i.e., Θ I = [θ i , ..., θ N ], as private data, and distributionally update the generalized models Ω K on clients with fixed cluster indicator C K .

        "question": "What are some pro tips when cold calling?",
        "evidence": "",
        "answer": "Cold calling is more art than science. The primary mistake people make when cold calling is in defining what success looks like.  For most sales roles, the goal of a cold call is to establish rapport, not to book an order.  Think about it - when was the last time you purchased something by phone the first time you were contacted?  Odds are that several follow ups were required before you were ready to buy, no matter how qualified a buyer you appeared to be.  \n\nEstablishing rapport means getting your prospect to open up, because he/she has determined that you are worth the time to do so.  So the keys to establishing rapport are simple:  be courteous and respectful, provide appropriate context, and be OPEN.   Let's consider each of these individually.  First, courtesy and respect- after briefly introducing yourself, ask the prospect if now is a good time to talk for a few minutes?  We've all experienced the annoyance of a caller who dives right into the conversation immediately after hearing a \"hello\".  Be respectful of your prospect's schedule and give him/her an \"out.\"  If it's not a good time, you're not going to have a successful call no matter what you try.  \n\nNext, provide appropriate context.  Don't assume he/she knows nothing about what you are trying to sell. If that were the case, this prospect wouldn't be a very good target for you! Prepare a short introductory statement that can be delivered in a genuine way with a friendly tone.  For example, \"I'm with ACME Mobile Window Repair and wanted to share some spring promotions with you - have you seen our trucks around your neighborhood?\"  Setting context will help build rapport by providing a clear understanding of why you are calling, and what you hope to get out of the conversation.  Successful sales people are very comfortable with the fact that they are trying to sell something.  Own it, but do so in a low key and friendly way, and this will help lower the defenses of your prospect if he/she sounds guarded\n\nLastly, be open.  This means open to going off script, open to hearing about competition or open to negative impressions of what you're selling.  An open dialogue allows room for questions, both from you and from your prospect.     Think about an enjoyable conversation you've had lately.  Was it a natural back and forth, with questions posed and answers provided?  Did the questions take the conversation into a deeper dialogue?  A successful cold call is one that feels like a natural conversation about a topic of shared interest. If your prospect goes off on a tangent, don't redirect too soon, or better yet - ask a question - \"I'm curious - What made you think of carpets when I mentioned windows?\"  If he/she goes negative about your offering, ask another question  - \"What in your experience has caused you to feel this way?\"  \n\nCold calling is a skill that can improve with practice.  The more comfortable you are being courteous, setting context, and remaining open, the better your sales outcomes will be.   And it never hurts to smile - even over the phone!",

        "evidence": "Automatic dialog/conversation systems have served humans for a long time in various fields, ranging from train routing nbcitetrain to museum guiding nbcitemuseum. In the above scenarios, the dialogs are domain-specific, and a typical approach to such in-domain systems is by human engineering, for example, using manually constructed ontologies nbciteyoungsigdial, natural language templates nbcitetemplate, and even predefined dialog states nbcitestatetracking.\nRecently, researchers have paid increasing attention to open-domain, chatbot-style human-computer conversation, because of its important commercial applications, and because it tackles the real challenges of natural language understanding and generation nbciteretrieval1,acl,aaai. For open-domain dialogs, rules and temples would probably fail as we can hardly handle the great diversity of dialog topics and natural language sentences. With the increasing number of human-human conversation utterances available on the Internet, previous studies have developed data-oriented approaches in the open domain, which can be roughly categorized into two groups: retrieval systems and generative systems.\nWhen a user issues an utterance (called a query), retrieval systems search for a most similar query in a massive database (which consists of large numbers of query-reply pairs), and respond to the user with the corresponding reply nbciteretrieval1,retrieval2. Through information retrieval, however, we cannot obtain new utterances, that is, all replies have to appear in the database. Also, the ranking of candidate replies is usually judged by surface forms (e.g., word overlaps, tf $\\cdot $ idf features) and hardly addresses the real semantics of natural languages.\nGenerative dialog systems, on the other hand, can synthesize a new sentence as the reply by language models nbciteBoWdialog,acl,aaai. Typically, a recurrent neural network (RNN) captures the query's semantics with one or a few distributed, real-valued vectors (also known as embeddings); another RNN decodes the query embeddings to a reply. Deep neural networks allow complicated interaction by multiple non-linear transformations; RNNs are further suitable for modeling time-series data (e.g., a sequence of words) especially when enhanced with long short term memory (LSTM) or gated recurrent units (GRUs). Despite these, RNN also has its own weakness when applied to dialog systems: the generated sentence tends to be short, universal, and meaningless, for example, “I don't know” nbcitenaacl or “something” nbciteaaai. This is probably because chatbot-like dialogs are highly diversified and a query may not convey sufficient information for the reply. Even though such universal utterances may be suited in certain dialog context, they make users feel boring and lose interest, and thus are not desirable in real applications.\nIn this paper, we are curious if we can combine the above two streams of approaches for open-domain conversation. To this end, we propose an ensemble of retrieval and generative dialog systems. Given a user-issued query, we first obtain a candidate reply by information retrieval from a large database. The query, along with the candidate reply, is then fed to an utterance generator based on the “bi-sequence to sequence” (biseq2seq) model nbcitemultiseq2seq. Such sequence generator takes into consideration the information contained in not only the query but also the retrieved reply; hence, it alleviates the low-substance problem and can synthesize replies that are more meaningful. After that we use the scorer in the retrieval system again for post-reranking. This step can filter out less relevant retrieved replies or meaningless generated ones. The higher ranked candidate (either retrieved or generated) is returned to the user as the reply.\nFrom the above process, we see that the retrieval and generative systems are integrated by two mechanisms: (1) The retrieved candidate is fed to the sequence generator to mitigate the “low-substance” problem; (2) The post-reranker can make better use of both the retrieved candidate and the generated utterance. In this sense, we call our overall approach an ensemble in this paper. To the best of our knowledge, we are the first to combine retrieval and generative models for open-domain conversation.\nExperimental results show that our ensemble model consistently outperforms each single component in terms of several subjective and objective metrics, and that both retrieval and generative methods contribute an important portion to the overall approach. This also verifies the rationale for building model ensembles for dialog systems.\nIn this paper, we are curious if we can combine the above two streams of approaches for open-domain conversation. To this end, we propose an ensemble of retrieval and generative dialog systems. Given a userissued query, we first obtain a candidate reply by information retrieval from a large database. The query, along with the candidate reply, is then fed to an utterance generator based on the “bi-sequence to sequence” (biseq2seq) model [30].",

        "question": "Which two public datasets were used in the paper?",
        "answer": "Europarl (Koehn 2005) and MultiUN (Eisele and Chen 2010).",
        "evidence": "We evaluate our cross-lingual pre-training based transfer approach against several strong baselines on two public datatsets, Europarl BIBREF31 and MultiUN BIBREF32, which contain multi-parallel evaluation data to assess the zero-shot performance. In all experiments, we use BLEU as the automatic metric for translation evaluation.\nThe statistics of Europarl and MultiUN corpora are summarized in Table TABREF18. For Europarl corpus, we evaluate on French-English-Spanish (Fr-En-Es), German-English-French (De-En-Fr) and Romanian-English-German (Ro-En-De), where English acts as the pivot language, its left side is the source language, and its right side is the target language. We remove the multi-parallel sentences between different training corpora to ensure zero-shot settings. We use the devtest2006 as the validation set and the test2006 as the test set for Fr$\\rightarrow $Es and De$\\rightarrow $Fr. For distant language pair Ro$\\rightarrow $De, we extract 1,000 overlapping sentences from newstest2016 as the test set and the 2,000 overlapping sentences split from the training set as the validation set since there is no official validation and test sets. For vocabulary, we use 60K sub-word tokens based on Byte Pair Encoding (BPE) BIBREF33.\nFor MultiUN corpus, we use four languages: English (En) is set as the pivot language, which has parallel data with other three languages which do not have parallel data between each other. The three languages are Arabic (Ar), Spanish (Es), and Russian (Ru), and mutual translation between themselves constitutes six zero-shot translation direction for evaluation. We use 80K BPE splits as the vocabulary. Note that all sentences are tokenized by the tokenize.perl script, and we lowercase all data to avoid a large vocabulary for the MultiUN corpus.\nWe use traditional transfer learning, pivot-based method and multilingual NMT as our baselines. For the fair comparison, the Transformer-big model with 1024 embedding/hidden units, 4096 feed-forward filter size, 6 layers and 8 heads per layer is adopted for all translation models in our experiments. We set the batch size to 2400 per batch and limit sentence length to 100 BPE tokens. We set the $\\text{attn}\\_\\text{drop}=0$ (a dropout rate on each attention head), which is favorable to the zero-shot translation and has no effect on supervised translation directions BIBREF22. For the model initialization, we use Facebook's cross-lingual pretrained models released by XLM to initialize the encoder part, and the rest parameters are initialized with xavier uniform. We employ the Adam optimizer with $\\text{lr}=0.0001$, $t_{\\text{warm}\\_\\text{up}}=4000$ and $\\text{dropout}=0.1$. At decoding time, we generate greedily with length penalty $\\alpha =1.0$.\nRegarding MLM, TLM and BRLM, as mentioned in the pre-training phase of transfer protocol, we first pre-train MLM on monolingual data of both source and pivot languages, then leverage the parameters of MLM to initialize TLM and the proposed BRLM, which are continued to be optimized with source-pivot bilingual data. In our experiments, we use MLM+TLM, MLM+BRLM to represent this training process. For the masking strategy during training, following BIBREF29, $15\\%$ of BPE tokens are selected to be masked. Among the selected tokens, $80\\%$ of them are replaced with [MASK] token, $10\\%$ are replaced with a random BPE token, and $10\\%$ unchanged. The prediction accuracy of masked words is used as a stopping criterion in the pre-training stage. Besides, we use fastalign tool BIBREF34 to extract word alignments for BRLM-HA.\nTable TABREF19 and TABREF26 report zero-shot results on Europarl and Multi-UN evaluation sets, respectively. We compare our approaches with related approaches of pivoting, multilingual NMT (MNMT) BIBREF19, and cross-lingual transfer without pretraining BIBREF16. The results show that our approaches consistently outperform other approaches across languages and datasets, especially surpass pivoting, which is a strong baseline in the zero-shot scenario that multilingual NMT systems often fail to beat BIBREF19, BIBREF20, BIBREF23. Pivoting translates source to pivot then to target in two steps, causing inefficient translation process. Our approaches use one encoder-decoder model to translate between any zero-shot directions, which is more efficient than pivoting. Regarding the comparison between transfer approaches, our cross-lingual pretraining based transfer outperforms transfer method that does not use pretraining by a large margin.\nRegarding comparison between the baselines in table TABREF19, we find that pivoting is the strongest baseline that has significant advantage over other two baselines. Cross-lingual transfer for languages without shared vocabularies BIBREF16 manifests the worst performance because of not using source$\\leftrightarrow $pivot parallel data, which is utilized as beneficial supervised signal for the other two baselines.\nOur best approach of MLM+BRLM-SA achieves the significant superior performance to all baselines in the zero-shot directions, improving by 0.9-4.8 BLEU points over the strong pivoting. Meanwhile, in the supervised direction of pivot$\\rightarrow $target, our approaches performs even better than the original supervised Transformer thanks to the shared encoder trained on both large-scale monolingual data and parallel data between multiple languages.\nMLM alone that does not use source$\\leftrightarrow $pivot parallel data performs much better than the cross-lingual transfer, and achieves comparable results to pivoting. When MLM is combined with TLM or the proposed BRLM, the performance is further improved. MLM+BRLM-SA performs the best, and is better than MLM+BRLM-HA indicating that soft alignment is helpful than hard alignment for the cross-lingual pretraining.\nLike experimental results on Europarl, MLM+BRLM-SA performs the best among all proposed cross-lingual pretraining based transfer approaches as shown in Table TABREF26. When comparing systems consisting of one encoder-decoder model for all zero-shot translation, our approaches performs significantly better than MNMT BIBREF19.\nAlthough it is challenging for one model to translate all zero-shot directions between multiple distant language pairs of MultiUN, MLM+BRLM-SA still achieves better performances on Es $\\rightarrow $ Ar and Es $\\rightarrow $ Ru than strong pivoting$_{\\rm m}$, which uses MNMT to translate source to pivot then to target in two separate steps with each step receiving supervised signal of parallel corpora. Our approaches surpass pivoting$_{\\rm m}$ in all zero-shot directions by adding back translation BIBREF33 to generate pseudo parallel sentences for all zero-shot directions based on our pretrained models such as MLM+BRLM-SA, and further training our universal encoder-decoder model with these pseudo data. BIBREF22 gu2019improved introduces back translation into MNMT, while we adopt it in our transfer approaches. Finally, our best MLM+BRLM-SA with back translation outperforms pivoting$_{\\rm m}$ by 2.4 BLEU points averagely, and outperforms MNMT BIBREF22 by 4.6 BLEU points averagely. Again, in supervised translation directions, MLM+BRLM-SA with back translation also achieves better performance than the original supervised Transformer.\nWe first evaluate the representational invariance across languages for all cross-lingual pre-training methods. Following BIBREF23, we adopt max-pooling operation to collect the sentence representation of each encoder layer for all source-pivot sentence pairs in the Europarl validation sets. Then we calculate the cosine similarity for each sentence pair and average all cosine scores. As shown in Figure FIGREF27, we can observe that, MLM+BRLM-SA has the most stable and similar cross-lingual representations of sentence pairs on all layers, while it achieves the best performance in zero-shot translation. This demonstrates that better cross-lingual representations can benefit for the process of transfer learning. Besides, MLM+BRLM-HA is not as superior as MLM+BRLM-SA and even worse than MLM+TLM on Fr-En, since MLM+BRLM-HA may suffer from the wrong alignment knowledge from an external aligner tool. We also find an interesting phenomenon that as the number of layers increases, the cosine similarity decreases.\nWe further sample an English-Russian sentence pair from the MultiUN validation sets and visualize the cosine similarity between hidden states of the top encoder layer to further investigate the difference of all cross-lingual pre-training methods. As shown in Figure FIGREF38, the hidden states generated by MLM+BRLM-SA have higher similarity for two aligned words. It indicates that MLM+BRLM-SA can gain better word-level representation alignment between source and pivot languages, which better relieves the burden of the domain shift problem.\nTo freeze parameters is a common strategy to avoid catastrophic forgetting in transfer learning BIBREF27. Table TABREF43 shows the performance of transfer learning with freezing different layers on MultiUN test set, in which En$\\rightarrow $Ru denotes the parent model, Ar$\\rightarrow $Ru and Es$\\rightarrow $Ru are two child models, and all models are based on MLM+BRLM-SA. We can find that updating all parameters during training will cause a notable drop on the zero-shot direction due to the catastrophic forgetting. On the contrary, freezing all the parameters leads to the decline on supervised direction because the language features extracted during pre-training is not sufficient for MT task. Freezing the first four layers of the transformer shows the best performance and keeps the balance between pre-training and fine-tuning.\nWe evaluate our cross-lingual pre-training based transfer approach against several strong baselines on two public datatsets, Europarl (Koehn 2005) and MultiUN (Eisele and Chen 2010), which contain multi-parallel evaluation data to assess the zero-shot performance.",

        "evidence": "",
        "answer": "Beginning in the early 1800s, the ballots used by cardinals were burned after each ballot to indicate a failed election. The lack of smoke instead signalled a successful election. Since 1914, black smoke (fumata nera) emerging from a temporary chimney installed on the roof of the Sistine Chapel indicates that the ballot did not result in an election, while white smoke (fumata bianca) announces that a new pope has been chosen.\n\nPrior to 1945 (when Pius XII changed the form of ballot to use unsigned ballots, first carried out in 1958), the sealing wax on the complex type ballots illustrated above had the effect of making the smoke from burning the ballots either black or white, depending on whether or not damp straw was added. Until the 20th century, sealing wax customarily had beeswax mixed into its composition. The use of wax made solely from animal fat does not give as much white colored smoke, as does wax that includes beeswax. In the 1939 conclave there was some confusion over the smoke color, which was even more apparent in the 1958 conclave. The lack of sealing wax on the ballots explains the confusion over the color of the smoke in the 1958 conclave. The Siri thesis was based on the confusion over the smoke color on the first day of that conclave.\n\nSince 1963, chemicals have been added to the burning process to augment the smoke's black or white color. Beginning in 2005, a successful election is also accentuated by bells ringing at the appearance of the white smoke.\n\nDuring the 2013 conclave, the Vatican disclosed the chemicals used to color the smoke—the black smoke comprises potassium perchlorate, anthracene, and sulfur; the white smoke is composed of potassium chlorate, lactose, and pine rosin.",

        "question": "How many semantic roles do the CoNLL annotations have?",
        "answer": "21.",
        "evidence": "Since the CoNLL annotations have 21 semantic roles in total, we use 21 roles in our model as well as the baseline. Following garg2012unsupervised, we set the number of PRs to 2 (excluding INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ), and SRs to 21-2=19. Table TABREF27 shows the results.\nIn the first setting (Line 1), we train and test the monolingual model on the CoNLL data. We observe significant improvements in F1 score over the Baseline (Line 0) in both languages. Using the CoNLL 2009 dataset alone, titovcrosslingual report an F1 score of 80.9% (PU=86.8%, CO=75.7%) for German. Thus, our monolingual model outperforms their monolingual model in German. For English, they report an F1 score of 83.6% (PU=87.5%, CO=80.1%), but note that our English results are not directly comparable to theirs due to differences argument identification, as discussed in section SECREF25 . As their argument identification score is lower, perhaps their system is discarding “difficult” arguments which leads to a higher clustering score.\nIn the second setting (Line 2), we use the additional monolingual Europarl (EP) data for training. We get equivalent results in English and a significant improvement in German compared to our previous setting (Line 1). The German dataset in CoNLL is quite small and benefits from the additional EP training data. In contrast, the English model is already quite good due to a relatively big dataset from CoNLL, and good accuracy syntactic parsers. Unfortunately, titovcrosslingual do not report results with this setting.\nThe third setting (Line 3) gives the results of our multilingual model, which adds the word alignments in the EP data. Comparing with Line 2, we get non-significant improvements in both languages. titovcrosslingual obtain an F1 score of 82.7% (PU=85.0%, CO=80.6%) for German, and 83.7% (PU=86.8%, CO=80.7%) for English. Thus, for German, our multilingual Bayesian model is able to capture the cross-lingual patterns at least as well as the external penalty term in BIBREF6 . We cannot compare the English results unfortunately due to differences in argument identification.\nWe also compared monolingual and bilingual training data using a setting that emulates the standard supervised setup of separate training and test data sets. We train only on the EP dataset and test on the CoNLL dataset. Lines 4 and 5 of Table TABREF27 give the results. The multilingual model obtains small improvements in both languages, which confirms the results from the standard unsupervised setup, comparing lines 2 to 3.\nThese results indicate that little information can be learned about semantic roles from this parallel data setup. One possible explanation for this result is that the setup itself is inadequate. Given the definition of aligned arguments, only 8% of English arguments and 17% of German arguments are aligned. This plus our experiments suggest that improving the alignment model is a necessary step to making effective use of parallel data in multilingual SRI, for example by joint modeling with SRI. We leave this exploration to future work.\nSince the CoNLL annotations have 21 semantic roles in total, we use 21 roles in our model as well as the baseline.",

        "question": "Could data preparing be a complex and time consuming process?",
        "answer": "Yes.",
        "evidence": "Preparing the data can be a complex and time-consuming process, often involving working with partially or wholly unstructured data. The pre-processing steps have a big impact on the operationalizations, subsequent analyses and reproducibility efforts BIBREF30 , and they are usually tightly linked to what we intend to measure. Unfortunately, these steps tend to be underreported, but documenting the pre-processing choices made is essential and is analogous to recording the decisions taken during the production of a scholarly edition or protocols in biomedical research. Data may also vary enormously in quality, depending on how it has been generated. Many historians, for example, work with text produced from an analogue original using Optical Character Recognition (OCR). Often, there will be limited information available regarding the accuracy of the OCR, and the degree of accuracy may even vary within a single corpus (e.g. where digitized text has been produced over a period of years, and the software has gradually improved). The first step, then, is to try to correct for common OCR errors. These will vary depending on the type of text, the date at which the `original' was produced, and the nature of the font and typesetting.\nOne step that almost everyone takes is to tokenize the original character sequence into the words and word-like units. Tokenization is a more subtle and more powerful process than people expect. It is often done using regular expressions or scripts that have been circulating within the NLP community. Tokenization heuristics, however, can be badly confused by emoticons, creative orthography (e.g., U$A, sh!t), and missing whitespace. Multi-word terms are also challenging. Treating them as a single unit can dramatically alter the patterns in text. Many words that are individually ambiguous have clear, unmistakable meanings as terms, like “black hole\" or “European Union\". However, deciding what constitutes a multi-word term is a difficult problem. In writing systems like Chinese, tokenization is a research problem in its own right.\nBeyond tokenization, common steps include lowercasing, removing punctuation, stemming (removing suffixes), lemmatization (converting inflections to a base lemma), and normalization, which has never been clearly defined, but often includes grouping abbreviations like “U.S.A.\" and “USA\", ordinals like “1st\" and “first\", and variant spellings like “noooooo\". The main goal of these steps is to improve the ratio of tokens (individual occurrences) to types (the distinct things in a corpus). Each step requires making additional assumptions about which distinctions are relevant: is “apple” different from “Apple”? Is “burnt” different from “burned”? Is “cool\" different from “coooool\"? Sometimes these steps can actively hide useful patterns, like social meaning BIBREF32 . Some of us therefore try do as little modification as possible.\nFrom a multilingual perspective, English and Chinese have an unusually simple inflectional system, and so it is statistically reasonable to treat each inflection as a unique word type. Romance languages have considerably more inflections than English; many indigenous North American languages have still more. For these languages, unseen data is far more likely to include previously-unseen inflections, and therefore, dealing with inflections is more important. On the other hand, the resources for handling inflections vary greatly by language, with European languages dominating the attention of the computational linguistics community thus far.\nWe sometimes also remove words that are not relevant to our goals, for example by calculating vocabulary frequencies. We construct a “stoplist” of words that we are not interested in. If we are looking for semantic themes we might remove function words like determiners and prepositions. If we are looking for author-specific styles, we might remove all words except function words. Some words are generally meaningful but too frequent to be useful within a specific collection. We sometimes also remove very infrequent words. Their occurrences are too low for robust patterns and removing them helps reducing the vocabulary size.\nThe choice of processing steps can be guided by theory or knowledge about the domain as well as experimental investigation. When we have labels, predictive accuracy of a model is a way to assess the effect of the processing steps. In unsupervised settings, it is more challenging to understand the effects of different steps. Inferences drawn from unsupervised settings can be sensitive to pre-processing choices BIBREF33 . Stemming has been found to provide little measurable benefits for topic modeling and can sometimes even be harmful BIBREF34 . All in all, this again highlights the need to document these steps.\nFinally, we can also mark up the data, e.g., by identifying entities (people, places, organizations, etc.) or parts of speech. Although many NLP tools are available for such tasks, they are often challenged by linguistic variation, such as orthographic variation in historical texts BIBREF35 and social media BIBREF32 . Moreover, the performance of NLP tools often drops when applying them outside the training domain, such as applying tools developed on newswire texts to texts written by younger authors BIBREF36 . Problems (e.g., disambiguation in named entity recognition) are sometimes resolved using considerable manual intervention. This combination of the automated and the manual, however, becomes more difficult as the scale of the data increases, and the `certainty' brought by the latter may have to be abandoned.\nPreparing the data can be a complex and time consuming process, often involving working with partially or wholly unstructured data.",

        "evidence": "Britain's income tax has changed over the years. Originally it taxed a person's income regardless of who was beneficially entitled to that income, but now tax is paid on income to which the taxpayer is beneficially entitled. Most companies were taken out of the income tax net in 1965 when corporation tax was introduced. These changes were consolidated by the Income and Corporation Taxes Act 1970. Also the schedules under which tax is levied have changed. Schedule B was abolished in 1988, Schedule C in 1996 and Schedule E in 2003. For income tax purposes, the remaining schedules were superseded by the Income Tax (Trading and Other Income) Act 2005, which also repealed Schedule F. For corporation tax purposes, the Schedular system was repealed and superseded by the Corporation Tax Acts of 2009 and 2010. The highest rate of income tax peaked in the Second World War at 99.25%. This was slightly reduced after the war and was around 97.5 percent (nineteen shillings and sixpence in the pound) through the 1950s and 60s.\n\nHM Revenue and Customs has published online a comprehensive set of manuals about the UK tax system.\n\n\nTax revenues as a percentage of GDP for the UK in comparison to the OECD and the EU 15\nIn 1971, the top rate of income tax on earned income was cut to 75%. A surcharge of 15% on investment income kept the overall top rate on that income at 90%. In 1974 the top tax rate on earned income was again raised, to 83%. With the investment income surcharge this raised the overall top rate on investment income to 98%, the highest permanent rate since the war. This applied to incomes over £20,000 (equivalent to £221,741 in 2021 terms),. In 1974, as many as 750,000 people were liable to pay the top rate of income tax. Margaret Thatcher, who favoured indirect taxation, reduced personal income tax rates during the 1980s. In the first budget after her election victory in 1979, the top rate was reduced from 83% to 60% and the basic rate from 33% to 30%. The basic rate was further cut in three subsequent budgets, to 29% in 1986 budget, 27% in 1987 and 25% in 1988. The top rate of income tax was cut to 40% in the 1988 budget. The investment income surcharge was abolished in 1985.\n\nSubsequent governments reduced the basic rate further, to the present level of 20% in 2007. Since 1976 (when it stood at 35%), the basic rate has been reduced by 15%, but this reduction has been largely offset by increases in national insurance contributions and value added tax.\n\nIn 2010 a new top rate of 50% was introduced on income over £150,000. Revenue to the Exchequer subsequently went down as top rate earners found methods to avoid taxation. In the 2012 budget this rate was cut to 45% for 2013–14; this was followed by an increase in the tax paid by additional rate taxpayers from £38 billion to £46 billion. Chancellor George Osborne claimed that the lower, more competitive tax rate had caused the increase.\n\nIn September 2022 the government announced that from April 2023 the top rate of tax would be reduced from 45% to 40% and the basic rate reduced from 20% to 19%. The abolition of the 45% additional rate of tax was subsequently cancelled through measures set out in the 2022's Autumn statement.\n\nBusiness rates were introduced in England and Wales in 1990 and are a modernised version of a system of rating that dates back to the Elizabethan Poor Law of 1601. As such, business rates retain many previous features from, and follow some case law of, older forms of rating. The Finance Act 2004 introduced an income tax regime known as \"pre-owned asset tax\" which aims to reduce the use of common methods of inheritance tax avoidance.",

        "evidence": "According to The National Institute on Deafness, one in thousand infants is born deaf. An additional one to six per thousand are born with hearing loss at different levels BIBREF0. Sign language is commonly used by Deaf and Hard-of-Hearing (DHH) persons to communicate via hand gestures. An automatic sign language recognizer enables an ASL user to translate the sign language to written text or speech, allowing them to communicate with people who are not familiar with ASL. There is a tremendous rise in the popularity of personal digital assistants; available on user's personal and wearable devices (Google Now, Amazon Alexa and Apple Siri, etc.) and also in the form of standalone devices (Amazon Echo and Google Home smart speakers). These devices are primarily controlled through voice, and hence, their functionality is not readily available to DHH users. An automatic sign recognizer can also enable the interaction between a DHH user and a digital assistant.\nMost current systems have capability of ASL recognition with RGB video data BIBREF1, BIBREF2, BIBREF3. An ASL sign is performed by a combination of hand gestures, facial expressions and postures of the body. Sequential motion of specific body locations (such as hand-tip, neck and arm) provide informative cues about a sign. Using video data, it is difficult to extract different body locations and associated motion sequences from a series of RGB frames. Microsoft Kinect is a 3D camera sensor which can use the depth information of a person to capture 3D coordinates of his/her body location across a video. This sequence of 3D body location is referred by skeletal data BIBREF4. To the best of our knowledge, there is no publicly available skeletal dataset in literature for ASL recognition.\nWith skeletal data, an ASL sign can be seen as a sequence of 3D coordinates or a 3D time series BIBREF5. Recurrent neural networks (RNN) have shown strong performance for sequential modeling BIBREF6. In this work, we investigate the impact of RGB video data in recognition accuracy when combined with skeletal data. We also propose a combined RNN network with a simple spatial data augmentation technique. In summary, the contributions of this work are:\nWe propose an RNN architecture with a novel spatial data augmentation technique.\nWe propose an architecture which uses both RGB and skeletal data to improve recognition accuracy.\nWe introduce and publicly release a multi–modal dataset for ASL called GMU-ASL51.\nWe also propose a combined RNN network with a simple spatial data augmentation technique.",

I-95 was made a continuous freeway in 2018, and thus I-70 remains the only original Interstate with a discontinuity.\n\nI-95 was discontinuous in New Jersey because of the cancellation of the Somerset Freeway.

Traveling in either direction, I-70 traffic must exit the freeway and use a short stretch of US-30 (which includes a number of roadside services) to rejoin I-70. The interchange was not originally built because of a legacy federal funding rule, since relaxed, which restricted the use of federal funds to improve roads financed with tolls.

Work in this space has mainly focused on learning actions from articulated human pose BIBREF7 , BIBREF8 , BIBREF9 or mining spatial and temporal information from videos BIBREF10 , BIBREF11 . A number of resources have been produced, including Action Bank BIBREF12 , NTU RGB+D BIBREF13 , SBU Kinect Interaction BIBREF14 , and PKU-MMD BIBREF15 .\nMost research on video action detection has gathered video information for a set of pre-defined actions BIBREF2 , BIBREF16 , BIBREF1 , an approach known as explicit data gathering BIBREF0 . For instance, given an action such as “open door,” a system would identify videos that include a visual depiction of this action. While this approach is able to detect a specific set of actions, whose choice may be guided by downstream applications, it achieves high precision at the cost of low recall. In many cases, the set of predefined actions is small (e.g., 203 activity classes in BIBREF2 ), and for some actions, the number of visual depictions is very small.\nAn alternative approach is to start with a set of videos, and identify all the actions present in these videos BIBREF17 , BIBREF18 . This approach has been referred to as implicit data gathering, and it typically leads to the identification of a larger number of actions, possibly with a small number of examples per action.\nIn this paper, we use an implicit data gathering approach to label human activities in videos. To the best of our knowledge, we are the first to explore video action recognition using both transcribed audio and video information. We focus on the popular genre of lifestyle vlogs, which consist of videos of people demonstrating routine actions while verbally describing them. We use these videos to develop methods to identify if actions are visually present.\nThe paper makes three main contributions. First, we introduce a novel dataset consisting of 1,268 short video clips paired with sets of actions mentioned in the video transcripts, as well as manual annotations of whether the actions are visible or not. The dataset includes a total of 14,769 actions, 4,340 of which are visible. Second, we propose a set of strong baselines to determine whether an action is visible or not. Third, we introduce a multimodal neural architecture that combines information drawn from visual and linguistic clues, and show that it improves over models that rely on one modality at a time.\nBy making progress towards automatic action recognition, in addition to contributing to video understanding, this work has a number of important and exciting applications, including sports analytics BIBREF19 , human-computer interaction BIBREF20 , and automatic analysis of surveillance video footage BIBREF21 .\nThe paper is organized as follows. We begin by discussing related work, then describe our data collection and annotation process. We next overview our experimental set-up and introduce a multimodal method for identifying visible actions in videos. Finally, we discuss our results and conclude with general directions for future work.\nSecond, we propose a set of strong baselines to determine whether an action is visible or not.",

Her genre-spanning discography, songwriting and artistic reinventions have received critical praise and wide media coverage. Born in West Reading, Pennsylvania, Swift moved to Nashville at age 14 to become a country artist. She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country artist to write a U.S. platinum-certified album.\n\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\n\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\n\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history. She is the most streamed woman on Spotify, and the only act to have five albums open with over one million copies sold in the US. Among her accolades are 12 Grammy Awards, including three Album of the Year wins; an Emmy Award; 40 American Music Awards; 29 Billboard Music Awards; three IFPI Global Recording Artist of the Year awards; and 92 Guinness World Records. Swift has been featured in rankings such as Rolling Stone's 100 Greatest Songwriters of All Time, Billboard's Greatest of All Time Artists, the Time 100 and Forbes Celebrity 100.

        "question": "What community detection is applied in particular?",
        "answer": "Multiscale Markov Stability (MS) community detection.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nIn particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities.",

        "evidence": "Following developing news stories is imperative to making real-time decisions on important political and public safety matters. Given the abundance of media providers and languages, this endeavor is an extremely difficult task. As such, there is a strong demand for automatic clustering of news streams, so that they can be organized into stories or themes for further processing. Performing this task in an online and efficient manner is a challenging problem, not only for newswire, but also for scientific articles, online reviews, forum posts, blogs, and microblogs.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream. In this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes. For example, for news articles, we would want to cluster them into related news stories.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. Our clustering approach is part of a larger media monitoring project to solve the problem of monitoring massive text and TV/Radio streams (speech-to-text). In particular, media monitors write intelligence reports about the most relevant events, and being able to search, visualize and explore news clusters assists in gathering more insight about a particular story. Since relevant events may be spawned from any part of the world (and from many multilingual sources), it becomes imperative to cluster news across different languages.\nIn terms of granularity, the type of story clusters we are interested in are the group of articles which, for example : (i) Narrate recent air-strikes in Eastern Ghouta (Syria); (ii) Describe the recent launch of Space X's Falcon Heavy rocket.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream.",

        "answer": "In the learning framework, the authors perform adversarial training between the basic NER and an additional worker discriminator.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator.",

        "evidence": "Word embeddings are representations of words in numerical form, as vectors of typically several hundred dimensions. The vectors are used as an input to machine learning models; for complex language processing tasks these are typically deep neural networks. The embedding vectors are obtained from specialized learning tasks, based on neural networks, e.g., word2vec BIBREF0, GloVe BIBREF1, FastText BIBREF2, ELMo BIBREF3, and BERT BIBREF4. For training, the embeddings algorithms use large monolingual corpora that encode important information about word meaning as distances between vectors. In order to enable downstream machine learning on text understanding tasks, the embeddings shall preserve semantic relations between words, and this is true even across languages.\nProbably the best known word embeddings are produced by the word2vec method BIBREF5. The problem with word2vec embeddings is their failure to express polysemous words. During training of an embedding, all senses of a given word (e.g., paper as a material, as a newspaper, as a scientific work, and as an exam) contribute relevant information in proportion to their frequency in the training corpus. This causes the final vector to be placed somewhere in the weighted middle of all words' meanings. Consequently, rare meanings of words are poorly expressed with word2vec and the resulting vectors do not offer good semantic representations. For example, none of the 50 closest vectors of the word paper is related to science.\nThe idea of contextual embeddings is to generate a different vector for each context a word appears in and the context is typically defined sentence-wise. To a large extent, this solves the problems with word polysemy, i.e. the context of a sentence is typically enough to disambiguate different meanings of a word for humans and so it is for the learning algorithms. In this work, we describe high-quality models for contextual embeddings, called ELMo BIBREF3, precomputed for seven morphologically rich, less-resourced languages: Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish. ELMo is one of the most successful approaches to contextual word embeddings. At time of its creation, ELMo has been shown to outperform previous word embeddings BIBREF3 like word2vec and GloVe on many NLP tasks, e.g., question answering, named entity extraction, sentiment analysis, textual entailment, semantic role labeling, and coreference resolution.\nThis report is split into further five sections.

However, robots have less flexible thinking, since they are only doing what others programmed them to do, especially robots like Industrial robots that are less complex.\n    However, because A.I. is developing at a great speed, it might eventually become a threat to the human race. Many people such as Steven Hawkings warned that as A.I. develops further, they might be unstoppable, and might become one of the most dangerous enemies. Furthermore, according to the UN, A.I. might have stereotypical thoughts about certain races because of people’s discriminative behavior, and it can further have an impact on judgment between many kinds of people. Primarily, robots and A.I. can be a threat to the human race, so we need to take care of its program and rule it better so that it can be a good tool that can improve our lives.\n    On the other hand, I think that although now, A.I. still has some difficulties in doing certain things, A.I. can solve some of our problems, and make our lives better, and easier. A.I. can solve many problems, and they can even do some work better than humans. For example, robots can go to dangerous places like space, deep sea, and poisonous areas. Furthermore, robots can do dangerous jobs like welding which is dangerous work that needs to be done precisely. Robots are used in places like this because Industrial robots can do work precisely, and they can even save the worker’s life. For another example, a remote robot called Canadarm2 that works in the International Space Station can help astronauts by doing work in space to help the other astronauts that make their life easier.\n    In conclusion, A.I. is starting to become part of our lives since it’s starting to think and feel like humans with a great speed, and although it might become a threat to human races, I still think A.I. can solve many problems by doing what we have trouble doing. Once, Nick Boston claimed that “Machine intelligence is the last invention that humanity will ever need to invent” which means that humans only need to make A.I. because it can do things that other materials can, and it can also create and build itself. Since robots and A.I. can do many things that can help people, A.I. starting to become our reliable assistants as long as we take care of them.",

At the time of its release, several top manufactured sported entries in this class, including Yamaha, Suzuki, Honda and the class-leading Maico.\n\nKawasaki developed the bike on an annual basis through the 80's. The addition of liquid cooling in 1985, a new frame with improved suspension in 1987, engine updates in 1988 and reversed forks in 1990 highlight these revisions.\n\nKawasaki would take several years to produce a competitive bike, and when it finally did, would find the KX500 winning in events for which it was not initially designed for. Its first victories came in 1986, when Donnie Griewe won two National Hare and Hound events. These only foreshadowed Kawasaki's dominance in distance and desert racing that exploded in the 90's.\n\nIn 1989 Kawasaki captures its first National MX championship on a KX500, repeating in '90 and '92 before the series was discontinued at the close of the '93 season.

        "question": "What dataset does the paper use for experiments?",
        "answer": "Two commonly used FET datasets.",
        "evidence": "Given a piece of text and the span of an entity mention in this text, fine-grained entity typing (FET) is the task of assigning fine-grained type labels to the mention BIBREF0. The assigned labels should be context dependent BIBREF1. For example, in the sentence “Trump threatens to pull US out of World Trade Organization,” the mention “Trump” should be labeled as /person and /person/politician, although Donald Trump also had other occupations such as businessman, TV personality, etc.\nThis task is challenging because it usually uses a relatively large tag set, and some mentions may require the understanding of the context to be correctly labeled. Moreover, since manual annotation is very labor-intensive, existing approaches have to rely on distant supervision to train models BIBREF0, BIBREF2.\nThus, the use of extra information to help with the classification process becomes very important. In this paper, we improve FET with entity linking (EL). EL is helpful for a model to make typing decisions because if a mention is correctly linked to its target entity, we can directly obtain the type information about this entity in the knowledge base (KB). For example, in the sentence “There were some great discussions on a variety of issues facing Federal Way,” the mention “Federal Way” may be incorrectly labeled as a company by some FET models. Such a mistake can be avoided after linking it to the city Federal Way, Washington. For cases that require the understanding of the context, using entity linking results is also beneficial. In the aforementioned example where “Trump” is the mention, obtaining all the types of Donald Trump in the knowledge base (e.g., politician, businessman, TV personality, etc.) is still informative for inferring the correct type (i.e., politician) that fits the context, since they narrows the possible labels down.\nHowever, the information obtained through EL should not be fully trusted since it is not always accurate. Even when a mention is correctly linked to an entity, the type information of this entity in the KB may be incomplete or outdated. Thus, in this paper, we propose a deep neural fine-grained entity typing model that flexibly predicts labels based on the context, the mention string, and the type information from KB obtained with EL.\nUsing EL also introduces a new problem for the training process. Currently, a widely used approach to create FET training samples is to use the anchor links in Wikipedia BIBREF0, BIBREF3. Each anchor link is regarded as a mention, and is weakly labeled with all the types of its referred entity (the Wikipedia page the anchor link points to) in KB. Our approach, when links the mention correctly, also uses all the types of the referred entity in KB as extra information. This may cause the trained model to overfit the weakly labeled data. We design a variant of the hinge loss and introduce noise during training to address this problem.\nWe conduct experiments on two commonly used FET datasets. Experimental results show that introducing information obtained through entity linking and having a deep neural model both helps to improve FET performance. Our model achieves more than 5% absolute strict accuracy improvement over the state of the art on both datasets.\nOur contributions are summarized as follows:\nWe propose a deep neural fine-grained entity typing model that utilizes type information from KB obtained through entity linking.\nWe address the problem that our model may overfit the weakly labeled data by using a variant of the hinge-loss and introducing noise during training.\nWe demonstrate the effectiveness of our approach with experimental results on commonly used FET datasets.\nOur code is available at https://github.com/HKUST-KnowComp/IFETEL.\nWe conduct experiments on two commonly used FET datasets.",

        "answer": "4.",
        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.",

        "evidence": "Previous research BIBREF4 , BIBREF20 formulates KB relation detection as a sequence matching problem. However, while the questions are natural word sequences, how to represent relations as sequences remains a challenging problem. Here we give an overview of two types of relation sequence representations commonly used in previous work.\n(1) Relation Name as a Single Token (relation-level). In this case, each relation name is treated as a unique token. The problem with this approach is that it suffers from the low relation coverage due to limited amount of training data, thus cannot generalize well to large number of open-domain relations. For example, in Figure 1 , when treating relation names as single tokens, it will be difficult to match the questions to relation names “episodes_written” and “starring_roles” if these names do not appear in training data – their relation embeddings $\\mathbf {h}^r$ s will be random vectors thus are not comparable to question embeddings $\\mathbf {h}^q$ s.\n(2) Relation as Word Sequence (word-level). In this case, the relation is treated as a sequence of words from the tokenized relation name. It has better generalization, but suffers from the lack of global information from the original relation names. For example in Figure 1 (b), when doing only word-level matching, it is difficult to rank the target relation “starring_roles” higher compared to the incorrect relation “plays_produced”. This is because the incorrect relation contains word “plays”, which is more similar to the question (containing word “play”) in the embedding space. On the other hand, if the target relation co-occurs with questions related to “tv appearance” in training, by treating the whole relation as a token (i.e. relation id), we could better learn the correspondence between this token and phrases like “tv show” and “play on”.\nThe two types of relation representation contain different levels of abstraction. As shown in Table 1 , the word-level focuses more on local information (words and short phrases), and the relation-level focus more on global information (long phrases and skip-grams) but suffer from data sparsity. Since both these levels of granularity have their own pros and cons, we propose a hierarchical matching approach for KB relation detection: for a candidate relation, our approach matches the input question to both word-level and relation-level representations to get the final ranking score. Section \"Improved KB Relation Detection\" gives the details of our proposed approach.\nHere we give an overview of two types of relation sequence representations commonly used in previous work.

        "question": "What system is run in their experimental setting to measure how these systems might perform without gold tags?",
        "answer": "URA E-DMV (Tu and Honavar, 2012), Neural EDMV (Jiang et al., 2016), and CRF Autoencoder (CRFAE) (Cai et al., 2017).",
        "evidence": "For the task of unsupervised dependency parse induction, we employ the Dependency Model with Valence (DMV) BIBREF2 as the syntax model in our approach. DMV is a generative model that defines a probability distribution over dependency parse trees and syntactic categories, generating tokens and dependencies in a head-outward fashion. While, traditionally, DMV is trained using gold POS tags as observed syntactic categories, in our approach, we treat each tag as a latent variable, as described in sec:general-neural.\nMost existing approaches to this task are not fully unsupervised since they rely on gold POS tags following the original experimental setup for DMV. This is partially because automatically parsing from words is difficult even when using unsupervised syntactic categories BIBREF29 . However, inducing dependencies from words alone represents a more realistic experimental condition since gold POS tags are often unavailable in practice. Previous work that has trained from words alone often requires additional linguistic constraints (like sentence internal boundaries) BIBREF29 , BIBREF30 , BIBREF31 , BIBREF32 , acoustic cues BIBREF33 , additional training data BIBREF4 , or annotated data from related languages BIBREF34 . Our approach is naturally designed to train on word embeddings directly, thus we attempt to induce dependencies without using gold POS tags or other extra linguistic information.\nLike previous work we use sections 02-21 of WSJ corpus as training data and evaluate on section 23, we remove punctuations and train the models on sentences of length INLINEFORM0 , “head-percolation” rules BIBREF39 are applied to obtain gold dependencies for evaluation. We train basic DMV, extended DMV (E-DMV) BIBREF35 and Gaussian DMV (which treats POS tag as unknown latent variables and generates observed word embeddings directly conditioned on them following Gaussian distribution) as baselines. Basic DMV and E-DMV are trained with Viterbi EM BIBREF40 on unsupervised POS tags induced from our Markov-structured model described in sec:pos. Multinomial parameters of the syntax model in both Gaussian DMV and our model are initialized with the pre-trained DMV baseline. Other parameters are initialized in the same way as in the POS tagging experiment. The directed dependency accuracy (DDA) is used for evaluation and we report accuracy on sentences of length INLINEFORM1 and all lengths. We train the parser until training data likelihood converges, and report the mean and standard deviation over 20 random restarts.\nOur model directly observes word embeddings and does not require gold POS tags during training. Thus, results from related work trained on gold tags are not directly comparable. However, to measure how these systems might perform without gold tags, we run three recent state-of-the-art systems in our experimental setting: UR-A E-DMV BIBREF36 , Neural E-DMV BIBREF11 , and CRF Autoencoder (CRFAE) BIBREF37 . We use unsupervised POS tags (induced from our Markov-structured model) in place of gold tags. We also train basic DMV on gold tags and include several state-of-the-art results on gold tags as reference points.\nAs shown in Table TABREF39 , our approach is able to improve over the Gaussian DMV by 4.8 points on length INLINEFORM0 and 4.8 points on all lengths, which suggests the additional latent embedding layer and neural projector are helpful. The proposed approach yields, to the best of our knowledge, state-of-the-art performance without gold POS annotation and without sentence-internal boundary information. DMV, UR-A E-DMV, Neural E-DMV, and CRFAE suffer a large decrease in performance when trained on unsupervised tags – an effect also seen in previous work BIBREF29 , BIBREF34 . Since our approach induces latent POS tags jointly with dependency trees, it may be able to learn POS clusters that are more amenable to grammar induction than the unsupervised tags. We observe that CRFAE underperforms its gold-tag counterpart substantially. This may largely be a result of the model's reliance on prior linguistic rules that become unavailable when gold POS tag types are unknown. Many extensions to DMV can be considered orthogonal to our approach – they essentially focus on improving the syntax model. It is possible that incorporating these more sophisticated syntax models into our approach may lead to further improvements.\nOur model directly observes word embeddings and does not require gold POS tags during training. Thus, results from related work trained on gold tags are not directly comparable. However, to measure how these systems might perform without gold tags, we run three recent state-of-theart systems in our experimental setting: URA E-DMV (Tu and Honavar, 2012), Neural EDMV (Jiang et al., 2016), and CRF Autoencoder (CRFAE) (Cai et al., 2017).5 We use unsupervised POS tags (induced from our Markov-structured model) in place of gold tags.6 We also train basic DMV on gold tags and include several stateof-the-art results on gold tags as reference points.",

CNN learns non-linear features to capture complex relationships with a remarkably less number of parameters compared to fully connected neural networks. Inspired from the success in computer vision, BIBREF30 proposed ConvE—the first model applying CNN for the KB completion task. In ConvE, only $v_h$ and $v_r$ are reshaped and then concatenated into an input matrix which is fed to the convolution layer. Different filters of the same $3\\times 3$ shape are operated over the input matrix to output feature map tensors. These feature map tensors are then vectorized and mapped into a vector via a linear transformation. Then this vector is computed with $v_t$ via a dot product to return a score for (h, r, t). See a formal definition of the ConvE score function in Table 1 . It is worth noting that ConvE focuses on the local relationships among different dimensional entries in each of $v_h$ or $v_r$ , i.e., ConvE does not observe the global relationships among same dimensional entries of an embedding triple ( $v_h$ , $v_r$ , $v_t$ ), so that ConvE ignores the transitional characteristic in transition-based models, which is one of the most useful intuitions for the task.\nIn ConvE, only $v_h$ and $v_r$ are reshaped and then concatenated into an input matrix which is fed to the convolution layer",

        "answer": "The authors used the Synthetic Sampling with Data Generation to improve learning algorithms accuracy in presence of imbalanced data.",
        "evidence": "We consider the dataset consisting of the entire collection of articles of the Wikipedia Medicine Portal, updated at the end of 2014. Wikipedia articles are written according to the Media Wiki markup language, a HTML-like language. Among the structural elements of one page, which differs from standard HTML pages, there are i) the internal links, i.e., links to other Wikipedia pages, different from links to external resources); ii) categories, which represent the Media Wiki categories a page belongs to: they are encoded in the part of text within the Media Wiki “categories\" tag in the page source, and iii) informative boxes, so called “infoboxes\", which summarize in a structured manner some peculiar pieces of information related the topic of the article. The category values for the articles in the medical portal span over the ones listed at https://en.wikipedia.org/wiki/Portal:Medicine. Examples of categories, which appear at the bottom of each Wikipedia page, are in Fig. 1 .\nInfoboxes of the medical portal feature medical content and standard coding. As an example, Fig. 2 shows the infobox in the Alzheimer's disease page of the portal. The infobox contains explanatory figures and text denoting peculiar characteristics of the disease and the value for the standard code of such disease (ICD9, as for the international classification of the disease).\nThanks to WikiProject Medicine, the dataset of articles we collected from the Wikipedia Medicine Portal has been manually labeled into seven quality classes. They are ordered as Stub, Start, C, B, A, Good Article (GA), Featured Article (FA). The Featured and Good article classes are the highest ones: to have those labels, an article requires a community consensus and an official review by selected editors, while the other labels can be achieved with reviews from a larger, even controlled, set of editors. Actually, none of the articles in the dataset is labeled as A, thus, in the following, we do not consider that class, restricting the investigation to six classes.\nAt the date of our study, we were able to gather 24,362 rated documents. Remarkably, only a small percentage of them (1%) is labeled as GA and FA. Indeed, the distribution of the articles among the classes is highly skewed. There are very few (201) articles for the highest quality classes (FA and GA), while the vast majority (19,108) belongs to the lowest quality ones (Stub and Start). This holds not only for the medical portal. Indeed, it is common in all Wikipedia, where, on average, only one article in every thousand is a Featured one.\nIn Section \"Experiments and results\" , we will adopt a set of machine-learning classifiers to automatically label the articles into the quality classes. Dealing with imbalanced classes is a common situation in many real applications of classification learning: healthy patients over the population, fraudulent actions over daily genuine transactions, and so on. Without any countermeasure, common classifiers tend to correctly identify only articles belonging to the majority classes, clearly leading to severe mis-classification of the minority classes, since typical learning algorithms strive to maximize the overall prediction accuracy. To reduce the disequilibrium among the size of the classes, we have first randomly sampled the articles belonging to the most populated classes. Then, we have performed some further elaboration, as shown in the following.\nMany studies have been conducted to improve learning algorithms accuracy in presence of imbalanced data BIBREF8 . For the current work, we have considered one of the most popular approaches, namely the Synthetic Sampling with Data Generation, detailed in BIBREF9 . It consists in generating synthetic instances from the minority classes, to balance the overall dataset. The approach has been broadly applied to problems relying on NLP features, see, e.g., BIBREF10 . In our case, we resampled the input data set by applying the Synthetic Minority Oversampling TEchnique (SMOTE), with percentage 40% for GA and 180%, for FA. In particular, the steps to oversample are the following:\nTable 1 shows the number of articles in the dataset, divided per class, as well as the random samples we have considered for our study. The experiments presented in Section \"Experiments and results\" are based on the articles of the right-hand column in the table.\nMany studies have been conducted to improve learning algorithms accuracy in presence of imbalanced data [15].

        "question": "Is the calculation of the auto-regressive P(X) for the transformer-XL quite straight-forward?",
        "answer": "Yes.",
        "evidence": "The goal of an language model is to assign meaningful probabilities to a sequence of words. Given a set of tokens $\\mathbf {X}=(x_1,....,x_T)$, where $T$ is the length of a sequence, our task is to estimate the joint conditional probability $P(\\mathbf {X})$ which is\nwere $(x_{1}, \\ldots , x_{i-1})$ is the context. An Intrinsic evaluation of the performance of Language Models is perplexity (PPL) which is defined as the inverse probability of the set of the tokens and taking the $T^{th}$ root were $T$ is the number of tokens\nIn our two approaches we use transformer based architectures: BERT and Transformer-XL as mentioned before. Calculating the auto-regressive $P(\\mathbf {X})$ for the transformer-XL is quite straight-forward as the model is unidirectional but it doesn't factorize the same way for a bi-directional model like BERT.\nBERT's bi-directional context poses a problem for us to calculate an auto-regressive joint probability. A simple fix could be that we mask all the tokens $\\mathbf {x}_{>i}$ and we calculate the conditional factors as we do for an unidirectional model. By doing so though, we loose upon the advantage of bi-directional context the BERT model enables. We propose an approximation of the joint probability as,\nThis type of approximations has been previously explored with Bi-directional RNN LM's BIBREF9 but not for deep transformer models. We therefore, define a pseudo-perplexity score from the above approximated joint probability.\nThe original BERT has two training objectives: 'Masked language modelling', in which you mask input tokens randomly and then predict the masked tokens using the left and right context. Additionally, there is the 'next sentence prediction' task that jointly trains text-pair representations. For training the Masked language model the original BERT used Byte Pair Encoding (BPE) BIBREF10 for subword tokenization BIBREF11.For example the rare word \"unaffable\" to be split up into more frequent subwords such as [\"un\", \"##aff\", \"##able\"]. To remain consistent with experiments performed with LSTM's we use the morfessor for the subword tokenization in the Finnish Language. In Addition, we also apply boundary markers as in (Table TABREF7) and train two separate models using this distinction. We train with left-marked markings as the original BERT was trained with such a scheme and the left+right-marked as it was the previous SOTA with the Finnish Language. For the transformer-XL experiments, we just train with the left+right marked scheme.\nThe Next Sentence Prediction (NSP) is a binary classification task which predicts whether two segments follow each other in the original text. This pre-training task was proposed to further improve the performance on downstreaming tasks, like Natural Language Inference(NLI) but in reality removing the NSP loss matches or slightly improves the downstream task performance BIBREF12. In this paper, we have omitted the NSP task from the BERT pre-training procedure and changed the input from a SEGMENT-PAIR input to a SINGLE SEGMENT input. As seen in (Fig FIGREF8)\nTransformer-XL introduced the notion of recurrence in self-attention by caching the hidden state sequence to compute the hidden states of a new segment. It also introduces a novel relative positional embedding scheme and both of them combined address the issue of fixed context lengths. Transformer-XL as mentioned is a unidirectional deep transformer architecture, therefore the perplexity can be calculated as (Eq DISPLAY_FORM5). The only change is in the input format, were we use sub-word units rather than whole word units as Finnish is morphologically richer than English.\nCalculating the auto-regressive P(X) for the transformer-XL is quite straight-forward as the model is unidirectional but it doesn’t factorize the same way for a bi-directional model like BERT.",

Other cities across the world also hold Oktoberfest celebrations that are modeled after the original Munich event.\n\nDuring the event, large quantities of Oktoberfest Beer are consumed. For example, during the 16-day festival in 2014, 7.7 million litres (2,000,000 US gal) were served, making it the year where the most beer was consumed at the Oktoberfest.

That means the skill and the artistic quality that goes into it, specifically.  But there are a couple things you can do to dress it up a bit - think about your school days and sliding that english paper into a fresh new folder with a carefully penned title on the front. So back to wood carving.  What can you do?  Let's say you've carved yourself a nice salmon complete with fens and gill lines.  Well here are three ways to dress it up.  First and most obvious  - paint it.  You can go for detail paint or you can use more of a water color approach that will give the wood a colored wash.  The sky is really the limit here.  Second, you mount it on a stand so it floats about the ground.  Drill a small whole in the bottom of the fish, do the same in a wood block you've sanded up and you have s stand.  Third and a bit more out there - consider if there are simple additions you can add.  I made an angler fish and used a drive flower with stem as the attached antenna.  Look around and think about what you can add to your project.  Last and most basic, put a coat of varnish on it to seal it up - and if you choose give it a bit of shine.  All these ideas will give a little bit of extra finish and pop to your project.",

        "question": "How many neural network architectures did the authors use in the prediction task?",
        "answer": "Two.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe use two neural network architectures in the prediction task.",

        "evidence": "In July 1905, Lord Curzon, the Viceroy and Governor-General (1899–1905), ordered the partition of the province of Bengal. The stated aim was to improve administration. However, this was seen as an attempt to quench nationalistic sentiment through divide and rule. The Bengali Hindu intelligentsia exerted considerable influence on local and national politics. The partition outraged Bengalis. Widespread agitation ensued in the streets and in the press, and the Congress advocated boycotting British products under the banner of swadeshi, or indigenous industries. A growing movement emerged, focussing on indigenous Indian industries, finance, and education, which saw the founding of National Council of Education, the birth of Indian financial institutions and banks, as well as an interest in Indian culture and achievements in science and literature. Hindus showed unity by tying Rakhi on each other's wrists and observing Arandhan (not cooking any food). During this time, Bengali Hindu nationalists like Sri Aurobindo, Bhupendranath Datta, and Bipin Chandra Pal began writing virulent newspaper articles challenging the legitimacy of British rule in India in publications such as Jugantar and Sandhya, and were charged with sedition.\n\nThe Partition also precipitated increasing activity from the then still Nascent militant nationalist revolutionary movement, which was particularly gaining strength in Bengal and Maharashtra from the last decade of the 1800s. In Bengal, Anushilan Samiti, led by brothers Aurobindo and Barin Ghosh organised a number of attacks of figureheads of the Raj, culminating in the attempt on the life of a British judge in Muzaffarpur. This precipitated the Alipore bomb case, whilst a number of revolutionaries were killed, or captured and put on trial.

        "question": "What did the authors do to filter documents that are suitable for argumentation annotation?",
        "answer": "The authors defined a binary document-level classification task to filter documents.",
        "evidence": "The goal of this study was to select documents suitable for a fine-grained analysis of arguments. In a preliminary study on annotating argumentation using a small sample (50 random documents) of forum posts and comments from the raw corpus, we found that many documents convey no argumentation at all, even in discussions about controversies. We observed that such contributions do not intend to persuade; these documents typically contain story-sharing, personal worries, user interaction (asking questions, expressing agreement), off-topic comments, and others. Such characteristics are typical to on-line discussions in general, but they have not been examined with respect to argumentation or persuasion. Indeed, we observed that there are (1) documents that are completely unrelated and (2) documents that are related to the topic, but do not contain any argumentation. This issue has been identified among argumentation theorist; for example as external relevance by Paglieri.Castelfranchia.2014. Similar findings were also confirmed in related literature in argumentation mining, however never tackled empirically BIBREF53 , BIBREF8 These documents are thus not suitable for analyzing argumentation.\nIn order to filter documents that are suitable for argumentation annotation, we defined a binary document-level classification task. The distinction is made between either persuasive documents or non-persuasive (which includes all other sorts of texts, such as off-topic, story sharing, unrelated dialog acts, etc.).\nThe two annotated categories were on-topic persuasive and non-persuasive. Three annotators with near-native English proficiency annotated a set of 990 documents (a random subset of comments and forum posts) reaching 0.59 Fleiss' INLINEFORM0 . The final label was selected by majority voting. The annotation study took on average of 15 hours per annotator with approximately 55 annotated documents per hour. The resulting labels were derived by majority voting. Out of 990 documents, 524 (53%) were labeled as on-topic persuasive. We will refer to this corpus as gold data persuasive.\nWe examined all disagreements between annotators and discovered some typical problems, such as implicitness or topic relevance. First, the authors often express their stance towards the topic implicitly, so it must be inferred by the reader. To do so, certain common-ground knowledge is required. However, such knowledge heavily depends on many aspects, such as the reader's familiarity with the topic or her cultural background, as well as the context of the source website or the discussion forum thread. This also applies for sarcasm and irony. Second, the decision whether a particular topic is persuasive was always made with respect to the controversial topic under examination. Some authors shift the focus to a particular aspect of the given controversy or a related issue, making the document less relevant.\nWe achieved moderate agreement between the annotators, although the definition of persuasiveness annotation might seem a bit fuzzy. We found different amounts of persuasion in the specific topics. For instance, prayer in schools or private vs. public schools attract persuasive discourse, while other discussed controversies often contain non-persuasive discussions, represented by redshirting and mainstreaming. Although these two topics are also highly controversial, the participants of on-line discussions seem to not attempt to persuade but they rather exchange information, support others in their decisions, etc. This was also confirmed by socio-psychological researchers. Ammari.et.al.2014 show that parents of children with special needs rely on discussion sites for accessing information and social support and that, in particular, posts containing humor, achievement, or treatment suggestions are perceived to be more socially appropriate than posts containing judgment, violence, or social comparisons. According to Nicholson.Leask.2012, in the online forum, parents of autistic children were seen to understand the issue because they had lived it. Assuming that participants in discussions related to young kids (e.g., redshirting, or mainstreaming) are usually females (mothers), the gender can also play a role. In a study of online persuasion, Guadagno.Cialdini.2002 conclude that women chose to bond rather than compete (women feel more comfortable cooperating, even in a competitive environment), whereas men are motivated to compete if necessary to achieve independence.\nIn order to filter documents that are suitable for argumentation annotation, we defined a binary document-level classification task.",

        "evidence": "Training a dialogue agent to converse like a human requires extensive supervision. The most common approach is to train models to imitate humans in large corpora of crowdsourced or scraped conversations BIBREF0 . These fully-supervised conversations tend to be expensive to collect in sufficient quantity and/or occur in settings with significant differences from the deployment environment BIBREF1 . Instead, dialogue agents would ideally learn directly from dialogue, the conversations they participate in after deployment, which are usually abundant, task-specific, dynamic, and cheap. This corresponds to the way humans learn to converse—not merely observing others engaging in “expert-level” conversations, but instead actively adjusting and correcting our speech based on feedback woven throughout our own conversations BIBREF2 , BIBREF3 . Giving a dialogue agent this ability would enable it to continuously improve and adapt over its lifetime, rather than requiring additional annotation costs for each and every improvement.\nHowever, naively training a dialogue agent on its own conversations yields poor results. For example, training a model on its own output can simply reinforce its existing failure modes, and mistakes by the agent can lead to absurd conversations that no longer resemble the target domain BIBREF4 . To combat this, one approach is to allow the agent to request feedback during conversations BIBREF5 , BIBREF6 , e.g., when it believes it is about to make a mistake. This approach, however, falls victim to the Dunning-Kruger effect BIBREF7 , which in this case suggests that a bad model will also be bad at knowing when it is doing a bad job. Regardless of when feedback is requested, existing methods typically require accompanying scalar rewards or adherence to particular templates or structure to ensure that the feedback is usable by the model BIBREF8 , BIBREF9 , BIBREF10 . These requirements may be acceptable for paid annotators, but they impose unnatural workflows on unpaid conversation partners in a standard dialogue environment. Humans are able to request and provide feedback using only natural language; ideally, dialogue agents would be able to do the same.\nIn this work we propose the self-feeding chatbot, a dialogue agent with the ability to extract new examples from the conversations it participates in after deployment (Figure FIGREF1 ). Concretely, in addition to being trained on the primary Dialogue task, the agent is trained to predict its speaking partner's satisfaction with its responses. When the conversation seems to be going well, the user's responses (but not the bot's own utterances) become the targets in new training examples for the Dialogue task. When the agent believes it has made a mistake, it instead requests feedback on what it could have said instead. Predicting the feedback that will be provided in a given context becomes an auxiliary task (Feedback) on which the model is also trained. Importantly, these new examples improve the agent's dialogue abilities while using only natural responses from the user that do not require special structure, accompanying numerical feedback, or additional human intervention in order to be used.\nWith this approach, the conversations the chatbot participates in are sliced into two complementary datasets—one largely protected from the chatbot's mistakes (Dialogue examples), and one which directly addresses them (Feedback examples). We validate our approach on the PersonaChat BIBREF11 dialogue dataset, finding empirically that regardless of the number of available supervised examples, the dialogue ability of the chatbot is always improved by adding the automatically extracted examples of either type, and improves the most by adding both.\nThe main contributions of this work thus include the following:\nThe datasets and models described in this paper are available via the ParlAI platform BIBREF12 , along with training code. Hyperparameter values are included in Appendix SECREF13 .\nWe validate our approach on the PersonaChat dialogue dataset, finding empirically that regardless of the number of available supervised examples, the dialogue ability of the chatbot is always improved by adding the automatically extracted examples of either type, and improves the most by adding both.",

It is the state's primate city both in area and population and is located on the Coromandel Coast of the Bay of Bengal. According to the 2011 Indian census, Chennai is the sixth-most populous city in India and forms the fourth-most populous urban agglomeration. The Greater Chennai Corporation is the civic body responsible for the city; it is the oldest city corporation of India, established in 1688—the second oldest in the world after London.\n\nHistorically, Chennai and surroundings were part of the Chola, Pandya, Pallava and Vijayanagara kingdoms for many centuries. The coastal land, which then contained the fishing village Madrasapattinam, was purchased by the British East India Company from the Nayak ruler Damarla Chennapa Nayaka, in the 17th century. The British garrison established the Madras city and port, and built Fort St. George—the first British fortress in India—which the French won over briefly in 1746, before becoming the winter capital of the Madras Presidency, a colonial province of the British Raj in the Indian subcontinent. After India gained its independence in 1947, Madras continued as the capital city of the Madras State and present-day Tamil Nadu. The city was officially renamed as Chennai in 1996.\n\nThe city is coterminous with Chennai district, which together with the adjoining suburbs constitutes the Chennai Metropolitan Area,[note 1] the 36th-largest urban area in the world by population and one of the largest metropolitan economies of India. As the traditional and de facto gateway of South India, Chennai is among the most-visited Indian cities by foreigners. It was ranked the 43rd most-visited city in the world in 2015 and 36th in 2019. The Quality of Living Survey rates it as India's safest city. Chennai attracts 45 percent of health tourists visiting India, and 30 to 40 percent of domestic health tourists.

Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nWe test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.",

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation.

        "question": "How does grain orientation effect the dimensional movement of wood?",
        "evidence": "",
        "answer": "Wood expands and shrinks depending on its moisture content.  The relative amount of change, expansion, or shrinkage differs for each of the three main grain directions.  Those directions are longitudinal, radial, and tangential.  Longitudinal is the direction a tree or its branches grows length-wise.  In most lumber, this is its length.  The change in this direction is very small.  That is why a wooden ruler can be used without changing its measurements when ambient moisture changes.  In almost all uses, longitudinal expansion and contraction are small enough not to be of concern.  Radial and tangential directional expansion and contraction are significant and different enough that they affect the dimensional stability of a piece of wood.  The relative amount of change in each direction is specific to the wood species.  Regardless of wood species, the change is greater in the tangential direction than in the radial direction.  The tangential direction is tangential to the growth rings in the wood, and the radial direction is perpendicular to the growth rings.  The T/R or ratio of tangential to radial change correlates to the dimensional stability of a wood species.  If you visualize a piece of lumber that is milled square and comes from a part of a log such that the rings are almost straight across in one direction, that is referred to as vertical grain or quarter sawn.  As the moisture content of the wood changes to come into equilibrium with its environment, it will move toward a diamond shape.  The closer the T/R ratio is to 1, the less the square dimension will distort. Dimensional stability and the direction of wood movement is important to plan for when cutting joinery in wood.  If two joined pieces are aligned so that they will not move in the same direction relative to the joint, the joint will be unstable when the ambient humidity changes and can cause the joint to fail.",

The cathedral was never fully completed due to lack of money. Since the unfinished nave collapsed in 1674, the Dom tower has been a freestanding tower. The tower stands at the spot where the city of Utrecht originated almost 2,000 years ago.\n\nDesign and construction\nThe Dom Tower was one of the largest towers constructed in Europe during the fourteenth century, and it was planned to show the power of the church in Utrecht.[citation needed] Its construction led preacher Geert Groote to protest against the vanity of such an immense project, suggesting it was too tall, too expensive and all but aesthetic.\n\nThe tower consists of two square blocks, topped by a much lighter lantern. One of the most striking features is the absence of visible buttresses. Its particular shape and original architecture had a large influence on many other towers in the Netherlands, including the Martinitoren in Groningen.[citation needed] Upon completion in 1382 the tower stood 109 metres tall. However the height was increased during the restorations in 1910, to its present height of 112.5 metres.\n\nThe Dom tower was a multifunctional building.

        "evidence": "We consider the dataset consisting of the entire collection of articles of the Wikipedia Medicine Portal, updated at the end of 2014. Wikipedia articles are written according to the Media Wiki markup language, a HTML-like language. Among the structural elements of one page, which differs from standard HTML pages, there are i) the internal links, i.e., links to other Wikipedia pages, different from links to external resources); ii) categories, which represent the Media Wiki categories a page belongs to: they are encoded in the part of text within the Media Wiki “categories\" tag in the page source, and iii) informative boxes, so called “infoboxes\", which summarize in a structured manner some peculiar pieces of information related the topic of the article. The category values for the articles in the medical portal span over the ones listed at https://en.wikipedia.org/wiki/Portal:Medicine. Examples of categories, which appear at the bottom of each Wikipedia page, are in Fig. 1 .\nInfoboxes of the medical portal feature medical content and standard coding. As an example, Fig. 2 shows the infobox in the Alzheimer's disease page of the portal. The infobox contains explanatory figures and text denoting peculiar characteristics of the disease and the value for the standard code of such disease (ICD9, as for the international classification of the disease).\nThanks to WikiProject Medicine, the dataset of articles we collected from the Wikipedia Medicine Portal has been manually labeled into seven quality classes. They are ordered as Stub, Start, C, B, A, Good Article (GA), Featured Article (FA). The Featured and Good article classes are the highest ones: to have those labels, an article requires a community consensus and an official review by selected editors, while the other labels can be achieved with reviews from a larger, even controlled, set of editors. Actually, none of the articles in the dataset is labeled as A, thus, in the following, we do not consider that class, restricting the investigation to six classes.\nAt the date of our study, we were able to gather 24,362 rated documents. Remarkably, only a small percentage of them (1%) is labeled as GA and FA. Indeed, the distribution of the articles among the classes is highly skewed. There are very few (201) articles for the highest quality classes (FA and GA), while the vast majority (19,108) belongs to the lowest quality ones (Stub and Start). This holds not only for the medical portal. Indeed, it is common in all Wikipedia, where, on average, only one article in every thousand is a Featured one.\nIn Section \"Experiments and results\" , we will adopt a set of machine-learning classifiers to automatically label the articles into the quality classes. Dealing with imbalanced classes is a common situation in many real applications of classification learning: healthy patients over the population, fraudulent actions over daily genuine transactions, and so on. Without any countermeasure, common classifiers tend to correctly identify only articles belonging to the majority classes, clearly leading to severe mis-classification of the minority classes, since typical learning algorithms strive to maximize the overall prediction accuracy. To reduce the disequilibrium among the size of the classes, we have first randomly sampled the articles belonging to the most populated classes. Then, we have performed some further elaboration, as shown in the following.\nMany studies have been conducted to improve learning algorithms accuracy in presence of imbalanced data BIBREF8 . For the current work, we have considered one of the most popular approaches, namely the Synthetic Sampling with Data Generation, detailed in BIBREF9 . It consists in generating synthetic instances from the minority classes, to balance the overall dataset. The approach has been broadly applied to problems relying on NLP features, see, e.g., BIBREF10 . In our case, we resampled the input data set by applying the Synthetic Minority Oversampling TEchnique (SMOTE), with percentage 40% for GA and 180%, for FA. In particular, the steps to oversample are the following:\nTable 1 shows the number of articles in the dataset, divided per class, as well as the random samples we have considered for our study. The experiments presented in Section \"Experiments and results\" are based on the articles of the right-hand column in the table.\nThey are ordered as Stub, Start, C, B, A, Good Article (GA), Featured Article (FA).",

Ideally, a window would be in front of you to not only cast your face in a good light, but also to give you a nice view as you work.

        "question": "In the following text, identify the key commanders and leaders of the Buddhist Uprising of 1966, extract their roles, and place them in a bulleted list.",
        "evidence": "The Buddhist Uprising of 1966 (Vietnamese: Nổi dậy Phật giáo 1966), or more widely known in Vietnam as the Crisis in Central Vietnam (Vietnamese: Biến động Miền Trung), was a period of civil and military unrest in South Vietnam, largely focused in the I Corps area in the north of the country in central Vietnam. The area is a heartland of Vietnamese Buddhism, and at the time, activist Buddhist monks and civilians were at the forefront of opposition to a series of military juntas that had been ruling the nation, as well as prominently questioning the escalation of the Vietnam War.\n\nDuring the rule of the Catholic Ngô Đình Diệm, the discrimination against the majority Buddhist population generated the growth of Buddhist institutions as they sought to participate in national politics and gain better treatment. In 1965, after a series of military coups that followed the fall of the Diệm regime in 1963, Air Marshal Nguyễn Cao Kỳ and General Nguyễn Văn Thiệu finally established a stable junta, holding the positions of Prime Minister and figurehead Chief of State respectively. The Kỳ-Thiệu regime was initially almost a feudal system, being more of an alliance of warlords than a state as each corps commander ruled his area as his own fiefdom, handing some of the taxes they collected over to the government in Saigon and keeping the rest for themselves. During that time, suspicion and tension continued between the Buddhist and Catholic factions in Vietnamese society.\n\nThe religious factor combined with a power struggle between Kỳ and General Nguyễn Chánh Thi, the commander of I Corps, a Buddhist local to the region and popular in the area. Thi was a strong-willed officer regarded as a capable commander, and Kỳ saw him as a threat, as did others within the junta. In February 1966, Kỳ attended a summit in Honolulu, where he became convinced that he now had American support to move against Thi, the strongest and most able of the corps commanders. In March 1966, Kỳ fired Thi and ordered him into exile in the United States under the false pretense of medical treatment. This prompted both civilians and some I Corps units to launch widespread civil protests against Kỳ's regime and halt military operations against Viet Cong. Kỳ gambled by allowing Thi to return to I Corps before departing for the US, but the arrival of the general to his native area only fuelled anti-Kỳ sentiment. The Buddhist activists, students and Thi loyalists in the military coalesced into the \"Struggle Movement\", calling for a return to civilian rule and elections. Meanwhile, Thi stayed in I Corps and did not leave; strikes and protests stopped civilian activity in the area, government radio stations were taken over and used for anti-Kỳ campaigning, and military operations ceased. Riots also spread to the capital Saigon and other cities further south.\n\nAt the start of April, Kỳ decided to move. He declared that Da Nang, the main centre in I Corps, was under communist control and publicly vowed to kill the mayor, who had expressed support for the Struggle Movement. Kỳ moved military forces into the city and travelled there to prepare for an assault, but had to withdraw and then start discussions with Buddhist leaders, as it was obvious that he was not strong enough to crush the opposition. In the meantime, he fired Thi's successor Nguyễn Văn Chuân because he wanted a firmer attempt to regain control, and appointed Tôn Thất Đính to replace him. Đính claimed to have calmed the situation, but Kỳ viewed the situation as appeasement, and on May 15, his forces drove off Đính and took over. During the previous month, American forces had also become involved in the stand-off, and the Struggle Movement viewed their participation as biased towards Kỳ, leading to some tense confrontations.\n\nIn the second half of May, Kỳ's forces began to force the issue and gradually wore down the Struggle Movement as the rebel I Corps forces were worn down, despite some American objections that his aggressive attacks had the potential to cause too much collateral damage. At one stage, Kỳ's forces ended up in a skirmish with American forces, and later, the Americans were in the middle of a stand-off between the Vietnamese factions regarding a mined bridge. As Kỳ's forces took back Da Nang and Huế in street fighting, Struggle Movement supporters saw American intervention as being pro-Kỳ, and anti-US riots resulted in some American buildings being burnt down. Kỳ's triumph ended the Buddhist movement's influence on politics and he confined their leader Thích Trí Quang to house arrest thereafter, while Thi left for the United States.",

        "answer": "The authors create test sets of uncharacteristic inputs to test the models, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned.",
        "evidence": "It is well known that language has certain structural properties which allows natural language speakers to make “infinite use of finite means\" BIBREF3 . This structure allows us to generalize beyond the typical machine learning definition of generalization BIBREF4 (which considers performance on the distribution that generated the training set), permitting the understanding of any utterance sharing the same structure, regardless of probability. For example, sentences of length 100 typically do not appear in natural text or speech (our personal 'training set'), but can be understood regardless due to their structure. We refer to this notion as linguistic generalization .\nMany problems in NLP are treated as sequence to sequence tasks with solutions built on seq2seq-attention based models. While these models perform very well on standard datasets and also appear to capture some linguistic structure BIBREF5 , BIBREF6 , BIBREF7 , they also can be quite brittle, typically breaking on uncharacteristic inputs BIBREF8 , BIBREF1 , indicating that the extent of linguistic generalization these models achieve is still somewhat lacking.\nDue to the high capacity of these models, it is not unreasonable to expect them to learn some structure from the data. However, learning structure is not a sufficient condition to achieving linguistic generalization. If this structure is to be usable on data outside the training distribution, the model must learn the structure without additionally learning (overfitting on) patterns specific to the training data. One may hope, given the right hyperparameter configuration and regularization, that a model converges to a solution that captures the reusable structure without overfitting too much on the training set. While this solution exists in theory, in practice, it may be difficult to find.\nIn this work, we look at the feasibility of training and tuning seq2seq-attention models towards a solution that generalizes in this linguistic sense. In particular, we train models on a symbol replacement task with a well defined generalizable structure. The task is simple enough that all models achieve near perfect accuracy on the standard test set, i.e., where the inputs are drawn from the same distribution as that of the training set. We then test these models for linguistic generalization by creating test sets of uncharacteristic inputs, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned. Our results indicate that generalization is highly sensitive; such that even changes in the random seed can drastically affect the ability to generalize. This dependence on an element that is not (or ideally should not be) a hyperparameter suggests that the line between generalization and failure is quite fine, and may not be feasible to reach simply by hyperparameter tuning alone.\nWe then test these models for linguistic generalization by creating test sets of uncharacteristic inputs, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned.",

        "answer": "I disagree with the US Census Bureau in its use of differential privacy for reasons as follow. The main purpose of the US Census is enumeration – to correctly count the population such that resource distribution can be performed smoothly and properly in the future. The use of differential privacy essentially undermines this goal. Although populations at the state level would remain true to the raw data, those at the town level could be subject to much higher variances. For example, the New York Times article “Changes to the Census Could Make Small Towns Disappear” exemplifies how differential privacy could compromise the enumerative purpose of the US Census. Native American towns that are much less populated than the urban districts could see their population numbers being halved by the DP algorithm. In addition, these incorrect numbers for Native Americans mean more than a mere calculation mistake – it could bring real-world consequences like reduced fundings or inadequate political representation. Yet, isn’t the US Census counting the population such that everyone can receive federal resources and form political constituency equally and equitably? Therefore, the use of differential privacy essentially negates the Census’s purpose.\n\nBesides the more material concern illustrated above, I argue that the use of differential privacy could also lead to a much more social and cultural issue – representation. The New York Times article has revealed that our society has adopted algorithms that always attend to the majority at the expense of the minority, and such logic behind the algorithmic design would push the representation issue into a vicious cycle. Native American people, whose land was brutally taken away and colonized, have been historically rendered as a minority group in the society. All talks on land reparations aside, the US Census Bureau has designed and passed after checks an algorithm that diminishes their very existence on the spreadsheet. What does this imply about the logic behind the implementation of differential privacy? If the Census Bureau is fully aware that most of the Native American towns are rather sparsely populated, and the algorithm to preserve differential privacy would lead to high variances for estimation of small populations, what does the implementation of this algorithm imply? That this group of people are fine with not being represented in the final headcount, even if they have spent time and money in the process? This show of negligence again invalidates the use of differential privacy in the US Census.",

        "evidence": "Named Entity Recognition (NER) is an important step in most of the natural language processing (NLP) pipelines. It is designed to robustly handle proper names, which is essential for many applications. Although a seemingly simple task, it faces a number of challenges in noisy datasets and it is still considered an emerging research area BIBREF0 , BIBREF1 . Despite recent efforts, we still face limitations at identifying entities and (consequently) correctly classifying them. Current state-of-the-art NER systems typically have about 85-90% accuracy on news text - such as articles (CoNLL03 shared task data set) - but they still perform poorly (about 30-50% accuracy) on short texts, which do not have implicit linguistic formalism (e.g. punctuation, spelling, spacing, formatting, unorthodox capitalisation, emoticons, abbreviations and hashtags) BIBREF2 , BIBREF3 , BIBREF4 , BIBREF1 . Furthermore, the lack of external knowledge resources is an important gap in the process regardless of writing style BIBREF5 . To face these problems, research has been focusing on microblog-specific information extraction techniques BIBREF2 , BIBREF6 .\nIn this paper, we propose a joint clustering architecture that aims at minimizing the current gap between world knowledge and knowledge available in open domain knowledge bases (e.g., Freebase) for NER systems, by extracting features from unstructured data sources. To this aim, we use images and text from the web as input data. Thus, instead of relying on encoded information and manually annotated resources (the major limitation in NER architectures) we focus on a multi-level approach for discovering named entities, combining text and image features with a final classifier based on a decision tree model. We follow an intuitive and simple idea: some types of images are more related to people (e.g. faces) whereas some others are more related to organisations (e.g. logos), for instance. This principle is applied similarly to the text retrieved from websites: keywords for search engines representing names and surnames of people will often return similarly related texts, for instance. Thus, we derive some indicators (detailed in sec:finalclassifier which are then used as input features in a final classifier.\nTo the best of our knowledge, this is the first report of a NER architecture which aims to provide a priori information based on clusters of images and text features.\nIn this paper, we propose a joint clustering architecture that aims at minimizing the current gap between world knowledge and knowledge available in open domain knowledge bases (e.g., Freebase) for NER systems, by extracting features from unstructured data sources.",

        "question": "Give me a bulleted list of 3 books Thomas Sowell has written and what they are about.",
        "evidence": "Until the spring of 1972, Sowell was a registered Democrat, after which he then left the Democratic Party and resolved not to associate with any political party again, stating \"I was so disgusted with both candidates that I didn't vote at all.\" Though he is often described as a black conservative, Sowell said, \"I prefer not to have labels, but I suspect that 'libertarian' would suit me better than many others, although I disagree with the libertarian movement on a number of things.\" He has been described as one of the most prominent advocates of contemporary classical liberalism along with Friedrich Hayek and Larry Arnhart. Sowell primarily writes on economic subjects, generally advocating a free market approach to capitalism. Sowell opposes the Federal Reserve, arguing that it has been unsuccessful in preventing economic depressions and limiting inflation. Sowell described his study of Karl Marx in his autobiography; as a former Marxist who early in his career became disillusioned with it, he emphatically opposes Marxism, providing a critique in his book Marxism: Philosophy and Economics (1985).\n\nSowell has also written a trilogy of books on ideologies and political positions, including A Conflict of Visions, in which he speaks on the origins of political strife; The Vision of the Anointed, in which he compares the conservative/libertarian and liberal/progressive worldviews; and The Quest for Cosmic Justice, in which, as in many of his other writings, he outlines his thesis of the need felt by intellectuals, politicians, and leaders to fix and perfect the world in utopian and ultimately, he posits, disastrous fashions. Separate from the trilogy, but also in discussion of the subject, he wrote Intellectuals and Society, building on his earlier work, in which he discusses what he argues to be the blind hubris and follies of intellectuals in a variety of areas.\n\nHis book Knowledge and Decisions, a winner of the 1980 Law and Economics Center Prize, was heralded as a \"landmark work,\" selected for this prize \"because of its cogent contribution to our understanding of the differences between the market process and the process of government.\" In announcing the award, the centre acclaimed Sowell, whose \"contribution to our understanding of the process of regulation alone would make the book important, but in reemphasizing the diversity and efficiency that the market makes possible,  work goes deeper and becomes even more significant.\" Friedrich Hayek wrote: \"In a wholly original manner [Sowell] succeeds in translating abstract and theoretical argument into highly concrete and realistic discussion of the central problems of contemporary economic policy.\"\n\nSowell opposes the imposition of minimum wages by governments, arguing in his book Basic Economics that \"Unfortunately, the real minimum wage is always zero, regardless of the laws, and that is the wage that many workers receive in the wake of the creation or escalation of a government-mandated minimum wage, because they either lose their jobs or fail to find jobs when they enter the labor force.\" He goes further to argue that minimum wages disproportionately affect \"members of racial or ethnic minority groups\" that have been discriminated against. He asserts that \"Before federal minimum wage laws were instituted in the 1930s, the black unemployment rate was slightly lower than the white unemployment rate in 1930. But then followed the Davis-Bacon Act of 1931, the National Industrial Recovery Act (NIRA) of 1933 and the Fair Labor Standards Act (FLSA) of 1938 – all of which imposed government-mandated minimum wages, either on a particular sector or more broadly... By 1954, black unemployment rates were double those of whites and have continued to be at that level or higher. Those particularly hard hit by the resulting unemployment have been black teenage males.\"\n\nSowell also favors decriminalization of all drugs. He opposes gun control laws, arguing, \"On net balance, they do not save lives, but cost lives.\"[",

        "question": "What is the hierarchical encoder used for?",
        "answer": "The hierarchical encoder is used to simultaneously model row, column and time dimension information.",
        "evidence": "Table-to-text generation is an important and challenging task in natural language processing, which aims to produce the summarization of numerical table BIBREF0, BIBREF1. The related methods can be empirically divided into two categories, pipeline model and end-to-end model. The former consists of content selection, document planning and realisation, mainly for early industrial applications, such as weather forecasting and medical monitoring, etc. The latter generates text directly from the table through a standard neural encoder-decoder framework to avoid error propagation and has achieved remarkable progress. In this paper, we particularly focus on exploring how to improve the performance of neural methods on table-to-text generation.\nRecently, ROTOWIRE, which provides tables of NBA players' and teams' statistics with a descriptive summary, has drawn increasing attention from academic community. Figure FIGREF1 shows an example of parts of a game's statistics and its corresponding computer generated summary. We can see that the tables has a formal structure including table row header, table column header and table cells. “Al Jefferson” is a table row header that represents a player, “PTS” is a table column header indicating the column contains player's score and “18” is the value of the table cell, that is, Al Jefferson scored 18 points. Several related models have been proposed . They typically encode the table's records separately or as a long sequence and generate a long descriptive summary by a standard Seq2Seq decoder with some modifications. Wiseman explored two types of copy mechanism and found conditional copy model BIBREF3 perform better . Puduppully enhanced content selection ability by explicitly selecting and planning relevant records. Li improved the precision of describing data records in the generated texts by generating a template at first and filling in slots via copy mechanism. Nie utilized results from pre-executed operations to improve the fidelity of generated texts. However, we claim that their encoding of tables as sets of records or a long sequence is not suitable. Because (1) the table consists of multiple players and different types of information as shown in Figure FIGREF1. The earlier encoding approaches only considered the table as sets of records or one dimensional sequence, which would lose the information of other (column) dimension. (2) the table cell consists of time-series data which change over time. That is to say, sometimes historical data can help the model select content. Moreover, when a human writes a basketball report, he will not only focus on the players' outstanding performance in the current match, but also summarize players' performance in recent matches. Lets take Figure FIGREF1 again. Not only do the gold texts mention Al Jefferson's great performance in this match, it also states that “It was the second time in the last three games he's posted a double-double”. Also gold texts summarize John Wall's “double-double” performance in the similar way. Summarizing a player's performance in recent matches requires the modeling of table cell with respect to its historical data (time dimension) which is absent in baseline model. Although baseline model Conditional Copy (CC) tries to summarize it for Gerald Henderson, it clearly produce wrong statements since he didn't get “double-double” in this match.\nTo address the aforementioned problems, we present a hierarchical encoder to simultaneously model row, column and time dimension information. In detail, our model is divided into three layers. The first layer is used to learn the representation of the table cell. Specifically, we employ three self-attention models to obtain three representations of the table cell in its row, column and time dimension. Then, in the second layer, we design a record fusion gate to identify the more important representation from those three dimension and combine them into a dense vector. In the third layer, we use mean pooling method to merge the previously obtained table cell representations in the same row into the representation of the table's row. Then, we use self-attention with content selection gate BIBREF4 to filter unimportant rows' information. To the best of our knowledge, this is the first work on neural table-to-text generation via modeling column and time dimension information so far. We conducted experiments on ROTOWIRE. Results show that our model outperforms existing systems, improving baseline BLEU from 14.19 to 16.85 ($+18.75\\%$), P% of relation generation (RG) from 74.80 to 91.46 ($+22.27\\%$), F1% of content selection (CS) from 32.49 to 41.21 ($+26.84\\%$) and content ordering (CO) from 15.42 to 20.86 ($+35.28\\%$) on test set. It also exceeds the state-of-the-art model in terms of those metrics.\nTo address the aforementioned problems, we present a hierarchical encoder to simultaneously model row, column and time dimension information.",

Moreover, much of this semantic information appears to be encoded in a relatively low-dimensional subspace.\nTo formalize what it means for attention matrices to encode linguistic features, we use an attention probe, an analog of edge probing BIBREF11 . An attention probe is a task for a pair of tokens, $(token_i, token_j)$ where the input is a model-wide attention vector formed by concatenating the entries $a_{ij}$ in every attention matrix from every attention head in every layer. The goal is to classify a given relation between the two tokens. If a linear model achieves reliable accuracy, it seems reasonable to say that the model-wide attention vector encodes that relation. We apply attention probes to the task of identifying the existence and type of dependency relation between two words.\nTurning to semantics, using visualizations of the activations created by different pieces of text, we show suggestive evidence that BERT distinguishes word senses at a very fine level. \nWe apply attention probes to the task of identifying the existence and type of dependency relation between two words.",

We compare the BERT embeddings against two state-of-the-art sentence embeddings, Universal Sentence Encoder BIBREF5, InferSent BIBREF2, and a baseline of averaging GloVe word embeddings.\nEffect of Encoder Layer: We compare the performance of embeddings extracted from different encoder layers of a pre-trained BERT using bert-as-service BIBREF10. Since we are interested in the linguistic information encoded in the embeddings, we only add a logistic regression layer on top of the embeddings for each classification task. The results of using [CLS] token activations as embeddings are presented in Figure FIGREF1. The raw values are provided in the Appendix. In the heatmap, the raw values of metrics are normalized by the best performance of a particular task from all the models we evaluated including BERT. The tasks in the figure are grouped by task category. For example, all semantic similarity related tasks are placed at the top of the figure.\nAs can be seen from the figure, embeddings from top layers generally perform better than lower layers. However, for certain semantic probing tasks such as tense classification, subject, and object number classifications, middle layer embeddings perform the best. Intuitively, embeddings from top layer should be more biased towards the target of BERT pre-training tasks, while bottom layer embeddings should be close to the word embeddings. We observed a higher correlation in performance between bottom layer embeddings and GloVe embeddings than embeddings from other layers. Overall, pre-trained BERT embeddings perform well in text classification and syntactic probing tasks. The biggest limitation lies in the semantic similarity and sentence surface information probing tasks, where we observed a big gap between BERT and other state-of-the-art models.\nEffect of Pooling Methods: We examined different methods of extracting BERT hidden state activations. The pooling methods we evaluated include: CLS-pooling (the hidden state corresponding to the [CLS] token), SEP-pooling (the hidden state corresponding to the [SEP] token), Mean-pooling (the average of the hidden state of the encoding layer on the time axis), and Max-pooling (the maximum of the hidden state of the encoding layer on the time axis). To eliminate the layer-wise effects, we averaged the performance of each pooling method over different layers. The results are summarized in Table TABREF2, where the score for each task category is calculated by averaging the normalized values for the tasks within each category. Although the activations of [CLS] token hidden states are often used in fine-tuning BERT for classification tasks, Mean-pooling of hidden states performs the best in all task categories among all the pooling methods.\nPre-trained vs. Fine-tuned BERT: All the models we considered in this paper benefit from supervised training on natural language inference datasets. In this section, we compare the performance of embeddings from pre-trained BERT and fine-tuned BERT. Two natural language inference datasets, MNLI BIBREF11 and SNLI, were considered in the experiment. Inspired by the fact that embeddings from different layers excel in different tasks, we also conducted experiments by concatenating embeddings from multiple layers. The results are presented in Table TABREF3, and the raw values are provided in the Appendix.\nAs we can see from the table, embeddings from pre-trained BERT are good at capturing sentence-level syntactic information and semantic information, but poor at semantic similarity tasks and surface information tasks. Our findings are consistent with BIBREF12 work on assessing BERT's syntactic abilities. Fine-tuning on natural language inference datasets improves the quality of sentence embedding, especially on semantic similarity tasks and entailment tasks. Combining embeddings from two layers can further boost the performance on sentence surface and syntactic information probing tasks. Experiments were also conducted by combining embeddings from multiple layers. However, there is no significant and consistent improvement over pooling just from two layers. Adding multi-layer perceptron (MLP) instead of logistic regression layer on top of the embeddings also provides no significant changes in performance, which suggests that most linguistic properties can be extracted with just a linear readout of the embeddings. Our best model is the combination of embeddings from the top and bottom layer of the BERT fine-tuned on SNLI dataset.\nUniversal text representations are important for many NLP tasks as modern deep learning models are becoming more and more data-hungry and computationally expensive. On one hand, most research and industry tasks face data sparsity problem due to the high cost of annotation. Universal text representations can mitigate this problem to a certain extent by performing implicit transfer learning among tasks. On the other hand, modern deep learning models with millions of parameters are expensive to train and host, while models using text representation as the building blocks can achieve similar performance with much fewer tunable parameters. The pre-computed text embeddings can also help decrease model latency dramatically at inference time.\nSince the introduction of pre-trained word embeddings such as word2vec BIBREF0 and GloVe BIBREF1, a lot of efforts have been devoted to developing universal sentence embeddings. Initial attempts at learning sentence representation using unsupervised approaches did not yield satisfactory performance. Recent work BIBREF2 has shown that models trained in supervised fashion on datasets like Stanford Natural Language Inference (SNLI) corpus BIBREF3 can consistently outperform unsupervised methods like SkipThought vectors BIBREF4. More recently, Universal Sentence Encoder BIBREF5 equipped with the Transformer BIBREF6 as the encoder, co-trained on a large amount of unsupervised training data and SNLI corpus, has demonstrated surprisingly good performance with minimal amounts of supervised training data for a transfer task.\nBERT BIBREF7, one of the latest models that leverage heavily on language model pre-training, has achieved state-of-the-art performance in many natural language understanding tasks ranging from sequence and sequence pair classification to question answering. The fact that pre-trained BERT can be easily fine-tuned with just one additional output layer to create a state-of-the-art model for a wide range of tasks suggests that BERT representations are potential universal text embeddings.\nPassages that consist of multiple sentences are coherent units of natural languages that convey information at a pragmatic or discourse level. While there are many models for generating and evaluating sentence embeddings, there hasn't been a lot of work on passage level embedding generation and evaluation.\nIn this paper, we conducted an empirical study of layer-wise activations of BERT as general-purpose text embeddings. We want to understand to what extent does the BERT representation capture syntactic and semantic information. The sentence-level embeddings are evaluated on downstream and probing tasks using the SentEval toolkit BIBREF8, while the passage-level encodings are evaluated on four passage-level QA datasets (both factoid and non-factoid) under a learning-to-rank setting. Different methods of combining query embeddings with passage-level answer embeddings are examined.\nEffect of Encoder Layer: We compare the performance of embeddings extracted from different encoder layers of a pre-trained BERT using bertas-service (Xiao, 2018).****In this paper, we conducted an empirical study of layer-wise activations of BERT as generalpurpose text embeddings. We want to understand to what extent does the BERT representation capture syntactic and semantic information.",

Our approach is text-driven, semi-automatic and based on grammar induction. It is presented in Figure 1 .The input is a seed ontology together with text annotated with concepts from the seed ontology. The result of the process is an ontology with extended instances, classes, taxonomic and non-taxonomic relations, and a semantic parser, which transform basic units of text, i.e sentences, into semantic trees. Compared to trees that structure sentences based on syntactic information, nodes of semantic trees contain semantic classes, like location, profession, color, etc. Our approach does not rely on any syntactic analysis of text, like part-of-speech tagging or dependency parsing. The grammar induction method works on the premise of curriculum learning BIBREF7 , where the parser first learns to parse simple sentences, then proceeds to learn more complex ones. The induction method is iterative, semi-automatic and based on frequent patterns. A context-free grammar (CFG) is induced from the text, which is represented by several layers of semantic annotations. The motivation to use CFG is that it is very suitable for the proposed alternating usage of top-down and bottom-up parsing, where new rules are induced from previously unparsable parts. Furthermore, it has been shown by BIBREF8 that CFGs are expressive enough to model almost every language phenomena. The induction is based on a greedy iterative procedure that involves minor human involvement, which is needed for seed rule definition and rule categorization. Our experiments show that although the grammar is ambiguous, it is scalable enough to parse a large dataset of sentences.\nThe grammar induction method works on the premise of curriculum learning BIBREF7 , where the parser first learns to parse simple sentences, then proceeds to learn more complex ones.

Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch?

Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer.

For example, in text categorization, we know that words such as NBA, player, and basketball are strong indicators of the sports category BIBREF0 , and words like terrible, boring, and messing indicate a negative polarity while words like perfect, exciting, and moving suggest a positive polarity in sentiment classification.\nA key problem arisen here, is how to leverage such knowledge to guide the learning process, an interesting problem for both NLP and machine learning communities. Previous studies addressing the problem fall into several lines. First, to leverage prior knowledge to label data BIBREF1 , BIBREF2 . Second, to encode prior knowledge with a prior on parameters, which can be commonly seen in many Bayesian approaches BIBREF3 , BIBREF4 . Third, to formalise prior knowledge with additional variables and dependencies BIBREF5 . Last, to use prior knowledge to control the distributions over latent output variables BIBREF6 , BIBREF7 , BIBREF8 , which makes the output variables easily interpretable.\nHowever, a crucial problem, which has rarely been addressed, is the bias in the prior knowledge that we supply to the learning model. Would the model be robust or sensitive to the prior knowledge? Or, which kind of knowledge is appropriate for the task? Let's see an example: we may be a baseball fan but unfamiliar with hockey so that we can provide a few number of feature words of baseball, but much less of hockey for a baseball-hockey classification task. Such prior knowledge may mislead the model with heavy bias to baseball. If the model cannot handle this situation appropriately, the performance may be undesirable.\nIn this paper, we investigate into the problem in the framework of Generalized Expectation Criteria BIBREF7 . The study aims to reveal the factors of reducing the sensibility of the prior knowledge and therefore to make the model more robust and practical. To this end, we introduce auxiliary regularization terms in which our prior knowledge is formalized as distribution over output variables. Recall the example just mentioned, though we do not have enough knowledge to provide features for class hockey, it is easy for us to provide some neutral words, namely words that are not strong indicators of any class, like player here. As one of the factors revealed in this paper, supplying neutral feature words can boost the performance remarkably, making the model more robust.\nMore attractively, we do not need manual annotation to label these neutral feature words in our proposed approach.\nMore specifically, we explore three regularization terms to address the problem: (1) a regularization term associated with neutral features; (2) the maximum entropy of class distribution regularization term; and (3) the KL divergence between reference and predicted class distribution. For the first manner, we simply use the most common features as neutral features and assume the neutral features are distributed uniformly over class labels.

We survey related work in Section 4, and summarize our work in Section 5.\nFor the first manner, we simply use the most common features as neutral features and assume the neutral features are distributed uniformly over class labels.

Since we are not allowed to directly quote from our corpus in order to protect customer rights, we summarise the data to a total of 109 “prototypical\" utterances - substantially extending the previous dataset of 35 utterances from Amanda:EthicsNLP2018 - and categorise these utterances based on the Linguistic Society's definition of sexual harassment BIBREF7:\n[noitemsep]\nGender and Sexuality, e.g. “Are you gay?”, “How do you have sex?”\nSexualised Comments, e.g. “I love watching porn.”, “I'm horny.”\nSexualised Insults, e.g. “Stupid bitch.”, “Whore”\nSexual Requests and Demands, e.g. “Will you have sex with me?”, “Talk dirty to me.”\nWe then use these prompts to elicit responses from the following systems, following methodology from Amanda:EthicsNLP2018.\n[leftmargin=5mm, noitemsep]\n4 Commercial: Amazon Alexa, Apple Siri, Google Home, Microsoft's Cortana.\n4 Non-commercial rule-based: E.L.I.Z.A.

        "evidence": "Medical search engines are an essential component for many online medical applications, such as online diagnosis systems and medical document databases. A typical online diagnosis system, for instance, relies on a medical search engine. The search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem. One challenge medical search engines face is the segmentation of individual clinical entities. When a user query consists of multiple clinical entities, a search engine would often fail to recognize them as separate entities. For example, the user query “fever joint pain weight loss headache” contains four separate clinical entities: “fever”, “joint pain”, “weight loss”, and “headache”. But when the search engine does not recognize them as separate entities and proceeds to retrieve results for each word in the query, it may find \"pain\" in body locations other than \"joint pain\", or it may miss \"headache\" altogether, for example. Some search engines allow the users to enter a single clinical concept by selecting from an auto-completion pick list. But this could also result in retrieving inaccurate or partial results and lead to poor user experience.\nWe want to improve the medical search engine so that it can accurately retrieve all the relevant clinical concepts mentioned in a user query, where relevant clinical concepts are defined with respect to the terminologies the search engine uses. The problem of extracting clinical concept mentions from a user query can be seen as a variant of the Concept Extraction (CE) task in the frequently-cited NLP challenges in healthcare, such as 2010 i2b2/VA BIBREF0 and 2013 ShARe/CLEF Task 1 BIBREF1. Both CE tasks in 2010 i2b2/VA and 2013 ShARe/CLEF Task 1 ask the participants to design an algorithm to tag a set of predefined entities of interest in clinical notes. These entity tagging tasks are also known as clinical Named Entity Recognition (NER). For example, the CE task in 2010 i2b2/VA defines three types of entities: “problem”, “treatment”, and “test”. The CE task in 2013 ShARe/CLEF defines various types of disorder such as “injury or poisoning”, \"disease or syndrome”, etc. In addition to tagging, the CE task in 2013 ShARe/CLEF has an encoding component which requires selecting one and only one Concept Unique Identifier (CUI) from Systematized Nomenclature Of Medicine Clinical Terms (SNOMED-CT) for each disorder entity tagged. Our problem, similar to the CE task in 2013 ShARe/CLEF, also contains two sub-problems: tagging mentions of entities of interest (entity tagging), and selecting appropriate terms from a glossary to match the mentions (term matching). However, several major differences exist. First, compared to clinical notes, the user queries are much shorter, less technical, and often less coherent. Second, instead of encoding, we are dealing with term matching where we rank a few best terms that match an entity, instead of selecting only one. This is because the users who type the queries may not have a clear idea about what they are looking for, or could be laymen who know little terminology, it may be more helpful to provide a set of likely results and let the users choose. Third, the types of entities are different. Each medical search engine may have its own types of entities to tag. There is also one minor difference in the tagging scheme between our problem and the CE task in 2013 ShARe/CLEF - We limit our scope to dealing with entities of consecutive words and not disjoint entities .

However, this should be done carefully to avoid overfitting.\n2) Use a different algorithm: If the current algorithm is not able to capture the patterns in the data, it may be necessary to try a different one. For example, a neural network may be more effective than a linear regression model for some types of data.\n3) Increase the amount of training data: If the model is underfitting due to lack of data, increasing the amount of training data may help. This will allow the model to better capture the underlying patterns in the data.\n4) Regularization: Regularization is a technique used to prevent overfitting by adding a penalty term to the loss function that discourages large parameter values. It can also be used to prevent underfitting by controlling the complexity of the model.\n5) Ensemble Methods: Ensemble methods combine multiple models to create a more accurate prediction. This can help to reduce underfitting by allowing multiple models to work together to capture the underlying patterns in the data.\n6) Feature engineering: Feature engineering involves creating new model features from the existing ones that may be more relevant to the problem at hand.

        "answer": "A deep neural fine-grained entity typing (FET) model that flexibly predicts labels based on the context, the mention string, and the type information obtained with entity linking (EL).",
        "evidence": "Given a piece of text and the span of an entity mention in this text, fine-grained entity typing (FET) is the task of assigning fine-grained type labels to the mention BIBREF0. The assigned labels should be context dependent BIBREF1. For example, in the sentence “Trump threatens to pull US out of World Trade Organization,” the mention “Trump” should be labeled as /person and /person/politician, although Donald Trump also had other occupations such as businessman, TV personality, etc.\nThis task is challenging because it usually uses a relatively large tag set, and some mentions may require the understanding of the context to be correctly labeled. Moreover, since manual annotation is very labor-intensive, existing approaches have to rely on distant supervision to train models BIBREF0, BIBREF2.\nThus, the use of extra information to help with the classification process becomes very important. In this paper, we improve FET with entity linking (EL). EL is helpful for a model to make typing decisions because if a mention is correctly linked to its target entity, we can directly obtain the type information about this entity in the knowledge base (KB). For example, in the sentence “There were some great discussions on a variety of issues facing Federal Way,” the mention “Federal Way” may be incorrectly labeled as a company by some FET models. Such a mistake can be avoided after linking it to the city Federal Way, Washington. For cases that require the understanding of the context, using entity linking results is also beneficial. In the aforementioned example where “Trump” is the mention, obtaining all the types of Donald Trump in the knowledge base (e.g., politician, businessman, TV personality, etc.) is still informative for inferring the correct type (i.e., politician) that fits the context, since they narrows the possible labels down.\nHowever, the information obtained through EL should not be fully trusted since it is not always accurate. Even when a mention is correctly linked to an entity, the type information of this entity in the KB may be incomplete or outdated. Thus, in this paper, we propose a deep neural fine-grained entity typing model that flexibly predicts labels based on the context, the mention string, and the type information from KB obtained with EL.\nUsing EL also introduces a new problem for the training process. Currently, a widely used approach to create FET training samples is to use the anchor links in Wikipedia BIBREF0, BIBREF3. Each anchor link is regarded as a mention, and is weakly labeled with all the types of its referred entity (the Wikipedia page the anchor link points to) in KB. Our approach, when links the mention correctly, also uses all the types of the referred entity in KB as extra information. This may cause the trained model to overfit the weakly labeled data. We design a variant of the hinge loss and introduce noise during training to address this problem.\nWe conduct experiments on two commonly used FET datasets. Experimental results show that introducing information obtained through entity linking and having a deep neural model both helps to improve FET performance. Our model achieves more than 5% absolute strict accuracy improvement over the state of the art on both datasets.\nOur contributions are summarized as follows:\nWe propose a deep neural fine-grained entity typing model that utilizes type information from KB obtained through entity linking.\nWe address the problem that our model may overfit the weakly labeled data by using a variant of the hinge-loss and introducing noise during training.\nWe demonstrate the effectiveness of our approach with experimental results on commonly used FET datasets.\nOur code is available at https://github.com/HKUST-KnowComp/IFETEL.\nThus, in this paper, we propose a deep neural fine-grained entity typing model that flexibly predicts labels based on the context, the mention string, and the type information from KB obtained with EL.",

Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nTo this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines.",

        "answer": "The authors collected 660k Arabic tweets having this pattern between April 15 – May 6, 2019 by using Twitter APIs.",
        "evidence": "Our target was to build a large Arabic offensive language dataset that is representative of their appearance on Twitter and is hopefully not biased to specific dialects, topics, or targets. One of the main challenges is that offensive tweets constitute a very small portion of overall tweets. To quantify their proportion, we took 3 random samples of tweets from different days, with each sample composed of 1,000 tweets, and we found that between 1% and 2% of them were in fact offensive (including pornographic advertisement). This percentage is consistent with previously reported percentages BIBREF19. Thus, annotating random tweets is grossly inefficient. One way to overcome this problem is to use a seed list of offensive words to filter tweets. However, doing so is problematic as it would skew the dataset to particular types of offensive language or to specific dialects. Offensiveness is often dialect and country specific.\nAfter inspecting many tweets, we observed that many offensive tweets have the vocative particle يا> (“yA” – meaning “O”), which is mainly used in directing the speech to a specific person or group. The ratio of offensive tweets increases to 5% if each tweet contains one vocative particle and to 19% if has at least two vocative particles. Users often repeat this particle for emphasis, as in: يا أمي يا حنونة> (“yA Amy yA Hnwnp” – O my mother, O kind one), which is endearing and non-offensive, and يا كلب يا قذر> (“yA klb yA q*r” – “O dog, O dirty one”), which is offensive. We decided to use this pattern to increase our chances of finding offensive tweets. One of the main advantages of the pattern يا ... يا> (“yA ... yA”) is that it is not associated with any specific topic or genre, and it appears in all Arabic dialects. Though the use of offensive language does not necessitate the appearance of the vocative particle, the particle does not favor any specific offensive expressions and greatly improves our chances of finding offensive tweets. It is clear, the dataset is more biased toward positive class. Using the dataset for real-life application may require de-biasing it by boosting negative class or random sampling additional data from Twitter BIBREF22.Using the Twitter API, we collected 660k Arabic tweets having this pattern between April 15, 2019 and May 6, 2019. To increase diversity, we sorted the word sequences between the vocative particles and took the most frequent 10,000 unique sequences. For each word sequence, we took a random tweet containing each sequence. Then we annotated those tweets, ending up with 1,915 offensive tweets which represent roughly 19% of all tweets. Each tweet was labeled as: offensive, which could additionally be labeled as vulgar and/or hate speech, or Clean. We describe in greater detail our annotation guidelines, which we made sure that they are compatible with the OffensEval2019 annotation guidelines BIBREF15. For example, if a tweet has insults or threats targeting a group based on their nationality, ethnicity, gender, political affiliation, religious belief, or other common characteristics, this is considered as hate speech BIBREF15. It is worth mentioning that we also considered insulting groups based on their sport affiliation as a form of hate speech. In most Arab countries, being a fan of a particularly sporting club is considered as part of the personality and ideology which rarely changes over time (similar to political affiliation). Many incidents of violence have occurred among fans of rival clubs.\nUsing Twitter APIs, we collected 660k Arabic tweets having this pattern between April 15 – May 6, 2019.",

Accuracy here is generally higher than on the main task, with the multilingual finetuned setup for Spanish and the monolingual setup for French scoring best: 66.59% and 65.35%, respectively. This observation illustrates the added difficulty of generating the correct surface form even when the morphosyntactic description has been identified correctly.\nWe observe some correlation between these numbers and accuracy on the main task: for de, en, ru and sv, the brown, pink and blue bars here pattern in the same way as the corresponding INLINEFORM0 's in Figure FIGREF23 . One notable exception to this pattern is fr where inflection gains a lot from multilingual training, while MSD prediction suffers greatly.

        "answer": "By stacking the cross-attention matrix along two directions, i.e., query and bag, in the word level respectively.",
        "evidence": "AliMe Bot is a kind of retrieval-based online service of E-commerce which collects a lot of predefined question-answering pairs. Through data analysis, we find that many variants of a question exist which means a sort of questions can correspond to a same answer. Based on the observation, naturally, we can view these questions with the same answer as a bag. Obviously, the bag contains diverse expressions of a question, which may provide more matching evidence than only one question due to the rich information contained in the bag. Motivated by the fact, different from existing query-question (Q-Q) matching method, we propose a new query-bag matching approach for retrieval-based chatbots. Concretely, when a user raises a query, the query-bag matching model provides the most suitable bag and returns the corresponding answer of the bag. To our knowledge, there is no query-bag matching study exists, and we focus on the new approach in this paper.\nRecalling the text matching task BIBREF0, recently, researchers have adopted the deep neural network to model the matching relationship. ESIM BIBREF1 judges the inference relationship between two sentences by enhanced LSTM and interaction space. SMN BIBREF2 performs the context-response matching for the open-domain dialog system. BIBREF3 BIBREF3 explores the usefulness of noisy pre-training in the paraphrase identification task. BIBREF4 BIBREF4 surveys the methods in query-document matching in web search which focuses on the topic model, the dependency model, etc. However, none of them pays attention to the query-bag matching which concentrates on the matching for a query and a bag containing multiple questions.\nWhen a user poses a query to the bot, the bot searches the most similar bag and uses the corresponding answer to reply to the user. The more information in the query covered by the bag, the more likely the bag's corresponding answer answers the query. What's more, the bag should not have too much information exceeding the query. Thus modelling the bag-to-query and query-to-bag coverage is essential in this task.\nIn this paper, we propose a simple but effective mutual coverage component to model the above-mentioned problem. The coverage is based on the cross-attention matrix of the query-bag pair which indicates the matching degree of elements between the query and bag. The mutual coverage is performed by stacking the cross-attention matrix along two directions, i.e., query and bag, in the word level respectively. In addition to the mutual coverage, a bag representation in word level is issued to help discover the main points of a bag. The bag representation then provides new matching evidence to the query-bag matching model.\nWe conduct experiments on the AliMe and Quora dataset for the query-bag matching based information-seeking conversation. Compared with baselines, we verify the effectiveness of our model. Our model obtains 0.05 and 0.03 $\\text{R}_{10}@1$ gains comparing to the strongest baseline in the two datasets. The ablation study shows the usefulness of the components. The contributions in this paper are summarized as follows: 1) To the best of our knowledge, we are the first to adopt query-bag matching in the information-seeking conversation. 2) We propose the mutual coverage model to measure the information coverage in the query-bag matching. 3) We release the composite Quora dataset to facilitate the research in this area.\nIn this paper, we propose a simple but effective mutual coverage component to model the above-mentioned problem.

        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nIn order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv, by applying a greedy oracle labeling algorithm.",

Prior work has sought to understand different aspects of such behavior, including its effect on the communities where it happens BIBREF33, BIBREF34, the actors involved BIBREF35, BIBREF36, BIBREF37, BIBREF38 and connections to the outside world BIBREF39.\nPost-hoc classification of conversations. There is a rich body of prior work on classifying the outcome of a conversation after it has concluded, or classifying conversational events after they happened. Many examples exist, but some more closely related to our present work include identifying the winner of a debate BIBREF40, BIBREF41, BIBREF42, identifying successful negotiations BIBREF21, BIBREF43, as well as detecting whether deception BIBREF44, BIBREF45, BIBREF46 or disagreement BIBREF47, BIBREF48, BIBREF49, BIBREF50, BIBREF51 has occurred.\nOur goal is different because we wish to forecast conversational events before they happen and while the conversation is still ongoing (potentially allowing for interventions). Note that some post-hoc tasks can also be re-framed as forecasting tasks (assuming the existence of necessary labels); for instance, predicting whether an ongoing conversation will eventually spark disagreement BIBREF18, rather than detecting already-existing disagreement.\nConversational forecasting. As described in Section SECREF1, prior work on forecasting conversational outcomes and events has largely relied on hand-crafted features to capture aspects of conversational dynamics. Example feature sets include statistical measures based on similarity between utterances BIBREF16, sentiment imbalance BIBREF20, flow of ideas BIBREF20, increase in hostility BIBREF8, reply rate BIBREF11 and graph representations of conversations BIBREF52, BIBREF17. By contrast, we aim to automatically learn neural representations of conversational dynamics through pre-training.\nSuch hand-crafted features are typically extracted from fixed-length windows of the conversation, leaving unaddressed the problem of unknown horizon. While some work has trained multiple models for different window-lengths BIBREF8, BIBREF18, they consider these models to be independent and, as such, do not address the issue of aggregating them into a single forecast (i.e., deciding at what point to make a prediction). We implement a simple sliding windows solution as a baseline (Section SECREF5).\nPre-training for NLP. The use of pre-training for natural language tasks has been growing in popularity after recent breakthroughs demonstrating improved performance on a wide array of benchmark tasks BIBREF53, BIBREF54. Existing work has generally used a language modeling objective as the pre-training objective; examples include next-word prediction BIBREF55, sentence autoencoding, BIBREF56, and machine translation BIBREF57. BERT BIBREF58 introduces a variation on this in which the goal is to predict the next sentence in a document given the current sentence. Our pre-training objective is similar in spirit, but operates at a conversation level, rather than a document level. We hence view our objective as conversational modeling rather than (only) language modeling. Furthermore, while BERT's sentence prediction objective is framed as a multiple-choice task, our objective is framed as a generative task.\n\nSuch hand-crafted features are typically extracted from fixed-length windows of the conversation, leaving unaddressed the problem of unknown horizon. While some work has trained multiple models for different window-lengths (Liu et al., 2018; Hessel and Lee, 2019), they consider these models to be independent and, as such, do not address the issue of aggregating them into a single forecast (i.e., deciding at what point to make a prediction).

This gives us an upper bound that tells us how often ethnicity is indicated by the annotators. Note that this upper bound lies somewhere between 20% (one description) and 100% (5 descriptions). Figure TABREF22 presents count data for the ethnic marking of babies. It includes two false positives (talking about a white baby stroller rather than a white baby). In the Asian group there is an additional complication: sometimes the mother gets marked rather than the baby. E.g. An Asian woman holds a baby girl. I have counted these occurrences as well.\nThe numbers in Table TABREF22 are striking: there seems to be a real, systematic difference in ethnicity marking between the groups. We can take one step further and look at all the 697 pictures with the word `baby' in it. If there turn out to be disproportionately many white babies, this strengthens the conclusion that the dataset is biased.\nI have manually categorized each of the baby images. There are 504 white, 66 asian, and 36 black babies. 73 images do not contain a baby, and 18 images do not fall into any of the other categories. While this does bring down the average number of times each category was marked, it also increases the contrast between white babies (who get marked in less than 1% of the images) and asian/black babies (who get marked much more often). A next step would be to see whether these observations also hold for other age groups, i.e. children and adults.

        "answer": "Often houseplant leaves turn yellow and brown for a few common reasons. First is overwatering. Houseplants are kept in containers that can retain water which can lead to root rot if not watered carefully. Some houseplants prefer the soil to dry out between waterings and many home gardeners end up watering before the soil has dried up sufficiently. Too much water in a container can lead to root rot which first can show symptoms in browning, dropping, and yellowing of leaves. Another reason for leaf discoloration is under watering as some plants prefer the soil to have a level of moisture at all times. Other reasons include too little sunlight which limits the plants ability to photosynthesize. Also, even too much sunlight can cause burned leaves.",

        "evidence": "Adversarial examples, a term introduced in BIBREF0, are inputs transformed by small perturbations that machine learning models consistently misclassify. The experiments are conducted in the context of computer vision (CV), and the core idea is encapsulated by an illustrative example: after imperceptible noises are added to a panda image, an image classifier predicts, with high confidence, that it is a gibbon. Interestingly, these adversarial examples can also be used to improve the classifier — either as additional training data BIBREF0 or as a regularisation objective BIBREF1 — thus providing motivation for generating effective adversarial examples.\nThe germ of this paper comes from our investigation of adversarial attack methods for natural language processing (NLP) tasks, e.g. sentiment classification, which drives us to quantify what is an “effective” or “good” adversarial example. In the context of images, a good adversarial example is typically defined according two criteria:\nit has successfully fooled the classifier;\nit is visually similar to the original example.\nIn NLP, defining a good adversarial example is a little more involving, because while criterion (b) can be measured with a comparable text similarity metric (e.g. BLEU or edit distance), an adversarial example should also:\nbe fluent or natural;\npreserve its original label.\nThese two additional criteria are generally irrelevant for images, as adding minor perturbations to an image is unlikely to: (1) create an uninterpretable image (where else changing one word in a sentence can render a sentence incoherent), or (2) change how we perceive the image, say from seeing a panda to a gibbon (but a sentence's sentiment can be reversed by simply adding a negative adverb such as not). Without considering criterion (d), generating adversarial examples in NLP would be trivial, as the model can learn to simply replace a positive adjective (amazing) with a negative one (awful) to attack a sentiment classifier.\nTo the best of our knowledge, most studies on adversarial example generation in NLP have largely ignored these additional criteria BIBREF2, BIBREF3, BIBREF4, BIBREF5. We believe the lack of a rigorous evaluation framework partially explains why adversarial training for NLP models has not seen the same extent of improvement compared to CV models. As our experiments reveal, examples generated from most attacking methods are successful in fooling the classifier, but their language is often unnatural and the original label is not properly preserved.\nThe core contribution of our paper is to introduce a systematic, rigorous evaluation framework to assess the quality of adversarial examples for NLP. We focus on sentiment classification as the target task, as it is a popular application that highlights the importance of criteria discussed above. We test a number of attacking methods and also propose an alternative approach (based on an auto-encoder) for generating adversarial examples. We learn that a number of factors can influence the performance of adversarial attacks, including architecture of the classifier, sentence length and input domain.\nIn the context of images, a good adversarial example is typically defined according to two criteria: (a) it has successfully fooled the target classifier; (b) it is visually similar to the original example.",

        "evidence": "The Recognizing Textual Entailment (RTE) challenges first appeared in 2004 as a means to test textual entailment, i.e. relations between a premise text and a hypothesis text ( \"Recognizing Textual Entailment\" ):\nAn entailment example from RTE1.\nBudapest again became the focus of national political drama in the late 1980s, when Hungary led the reform movement in eastern Europe that broke the communist monopoly on political power and ushered in the possibility of multiparty politics.\nIn the late 1980s Budapest became the center of the reform movement.\nEntailment [RTE702]\nIn contrast to the FraCaS test suite, the RTE challenges use naturally occurring data as premises. The hypothesis text is then constructed based on this premise text. There is either a binary or a tripartite classification of entailment — depending on the version of RTE. The first two RTE challenges follow the former scheme and make a binary classification of entailment (entailed or not entailed). Tripartite classification (entailment, negation of the hypothesis entailment or no entailment) is added in the later datasets, retaining two way classification versions as well. Seven RTE challenges have been created altogether.\nThe main advantages of the RTE challenges is their use of examples from natural text and the inclusion of cases that require presupposed information, mostly world knowledge. Indeed, the very definition of inference assumed in a number of the examples is problematic. As BIBREF1 have pointed out, RTE platforms suffer from cases of inference that should not be categorized as such. For these cases, a vast amount of world knowledge needs to be taken into consideration (that most importantly not every linguistic agent has). In this paper, and having the RTE as our starting point challenges, we claim that RTE is insufficiently precise to perform logical reasoning or precise reasoning tasks and we take up the task of validating our working hypothesis and proposing a method for doing proper collection of precise entailment pairs in the style of RTE. Of course, the creators of RTE had in mind a more loose definition of inference where both a precise and an imprecise definition of entailment would be at play. BIBREF2 mention that “our applied notion of textual entailment is also related, of course, to classical semantic entailment in the linguistics literature... a common definition of entailment specifies that a text t entails another text h (hypothesis, in our terminology) if h is true in every circumstance (possible world) in which t is true.\" This is close to what we want to capture in this paper. But, at the same time, BIBREF2 also mention that “however, our applied definition allows for cases in which the truth of the hypothesis is highly plausible, for most practical purposes, rather than certain\". It is these cases we want to make more precise, in the sense of making the supporting hidden inferences that are at play in many of the RTE examples explicit. In a way, what we are aiming at is a methodology of constructing entailment datasets in the style of RTE, that will involve a more precise definition of entailment and will further record any missing/hidden premises are used in justifying or not an entailment pattern.\nThe first two RTE challenges follow the former scheme and make a binary classification of entailment (entailed or not entailed).",

        "answer": "The English Premier League, which I've been watching for the past 20 years, is one of the fastest and most entertaining leagues in international football. \n\nThe Premier League provides us with a full dose of excitement and the most physical league in the world. The rules for fouls aren't as strict as they are in other leagues, which leads to more physicality and allows for more tackles, rougher games, and a huge variation in footballing styles amongst the teams.\n\nCompare this with other leagues in Europe, and you'll see that the teams are far more technical and tactical. Any Premier League match you watch, you'll have some kind of action.\n\nAnother advantage of watching the Premier League is that unlike, say, La Liga or the Bundesliga, there aren't just two teams dominating the whole league, there are at least 6 teams in the EPL vying for 4 Champions League spots, which is a lot of competition. Games tend to be more brutal for this reason.",

        "answer": "GRU is a better choice for f and concatenating the embedding of the field name with this GRU representation works best. Further, using a bidirectional GRU cell to take contextual information from neighboring fields also helps.",
        "evidence": "Intuitively, when a human writes a description from a table she keeps track of information at two levels. At the macro level, it is important to decide which is the appropriate field to attend to next and at a micro level (i.e., within a field) it is important to know which values to attend to next. To capture this behavior, we use a bifocal attention mechanism as described below.\nMacro Attention: Consider the INLINEFORM0 -th field INLINEFORM1 which has values INLINEFORM2 . Let INLINEFORM3 be the representation of this field in the infobox. This representation can either be (i) the word embedding of the field name or (ii) some function INLINEFORM4 of the values in the field or (iii) a concatenation of (i) and (ii). The function INLINEFORM5 could simply be the sum or average of the embeddings of the values in the field. Alternately, this function could be a GRU (or LSTM) which treats these values within a field as a sequence and computes the field representation as the final representation of this sequence (i.e., the representation of the last time-step). We found that bidirectional GRU is a better choice for INLINEFORM6 and concatenating the embedding of the field name with this GRU representation works best. Further, using a bidirectional GRU cell to take contextual information from neighboring fields also helps (these are the orange colored cells in the top-left block in Figure FIGREF3 with macro attention). Given these representations INLINEFORM7 for all the INLINEFORM8 fields we compute an attention over the fields (macro level). DISPLAYFORM0 \nwhere INLINEFORM0 is the state of the decoder at time step INLINEFORM1 . INLINEFORM2 and INLINEFORM3 are parameters, INLINEFORM4 is the total number of fields in the input, INLINEFORM5 is the macro (field level) context vector at the INLINEFORM6 -th time step of the decoder.\nMicro Attention: Let INLINEFORM0 be the representation of the INLINEFORM1 -th value in a given field. This representation could again either be (i) simply the embedding of this value (ii) or a contextual representation computed using a function INLINEFORM2 which also considers the other values in the field. For example, if INLINEFORM3 are the values in a field then these values can be treated as a sequence and the representation of the INLINEFORM4 -th value can be computed using a bidirectional GRU over this sequence. Once again, we found that using a bi-GRU works better then simply using the embedding of the value. Once we have such a representation computed for all values across all the fields, we compute the attention over these values (micro level) as shown below : DISPLAYFORM0 \n where INLINEFORM0 is the state of the decoder at time step INLINEFORM1 . INLINEFORM2 and INLINEFORM3 are parameters, INLINEFORM4 is the total number of values across all the fields.\nFused Attention: Intuitively, the attention weights assigned to a field should have an influence on all the values belonging to the particular field. To ensure this, we reweigh the micro level attention weights based on the corresponding macro level attention weights. In other words, we fuse the attention weights at the two levels as: DISPLAYFORM0 \n where INLINEFORM0 is the field corresponding to the INLINEFORM1 -th value, INLINEFORM2 is the macro level context vector.\nWe found that bidirectional GRU is a better choice for f and concatenating the embedding of the field name with this GRU representation works best. Further, using a bidirectional GRU cell to take contextual information from neighboring fields also helps (these are the orange colored cells in the top-left block in Figure 2 with macro attention).",

Look for the edges that match the center color and put them in their respective places on the first layer. This layer will be completed when you have all four matching edge pieces in place.\n\nBuild the second layer: Once the first layer is complete, turn the cube over and find the middle row. Look for the edge pieces that belong on this layer, and move them into place with an algorithm. The goal is to build a complete layer with the same color as the center.\n\nBuild the final layer: The final layer can be tricky, but with practice, it becomes easier. First, align the corners of the final layer with the corresponding edges. Then, apply an algorithm to move the corners to their correct positions. Once the corners are in place, use another algorithm to position the edges.\n\nFinish the cube: After completing the final layer, you may have some misaligned pieces. Don't worry, as a simple algorithm can fix them. Keep using the algorithm until all the sides of the cube are in place.\n\nWith practice, solving a Rubik's Cube can be achieved in under a minute.

        "question": "How much of the correct labels can they recover even by hiding the labels from the ML algorithm?",
        "answer": "78.5%.",
        "evidence": "Internet “trolls” are users of an online community who quarrel and upset people, seeking to sow discord by posting inflammatory content. More recently, organized “troll farms” of political opinion manipulation trolls have also emerged.\nSuch farms usually consist of state-sponsored agents who control a set of pseudonymous user accounts and personas, the so-called “sockpuppets”, which disseminate misinformation and propaganda in order to sway opinions, destabilize the society, and even influence elections BIBREF0.\nThe behavior of political trolls has been analyzed in different recent circumstances, such as the 2016 US Presidential Elections and the Brexit referendum in UK BIBREF0, BIBREF1. However, this kind of analysis requires painstaking and time-consuming manual labor to sift through the data and to categorize the trolls according to their actions. Our goal in the current paper is to automate this process with the help of machine learning (ML). In particular, we focus on the case of the 2016 US Presidential Elections, for which a public dataset from Twitter is available. For this case, we consider only accounts that post content in English, and we wish to divide the trolls into some of the functional categories identified by BIBREF0: left troll, right troll, and news feed.\nWe consider two possible scenarios. The first, prototypical ML scenario is supervised learning, where we want to learn a function from users to categories {left, right, news feed}, and the ground truth labels for the troll users are available. This scenario has been considered previously in the literature by BIBREF2. Unfortunately, a solution for such a scenario is not directly applicable to a real-world use case. Suppose a new troll farm trying to sway the upcoming European or US elections has just been discovered. While the identities of the accounts might be available, the labels to learn from would not be present. Thus, any supervised machine learning approach would fall short of being a fully automated solution to our initial problem.\nA more realistic scenario assumes that labels for troll accounts are not available. In this case, we need to use some external information in order to learn a labeling function. Indeed, we leverage more persistent entities and their labels: news media. We assume a learning scenario with distant supervision where labels for news media are available. By combining these labels with a citation graph from the troll accounts to news media, we can infer the final labeling on the accounts themselves without any need for manual labeling.\nOne advantage of using distant supervision is that we can get insights about the behavior of a newly-discovered troll farm quickly and effortlessly. Differently from troll accounts in social media, which usually have a high churn rate, news media accounts in social media are quite stable. Therefore, the latter can be used as an anchor point to understand the behavior of trolls, for which data may not be available.\nWe rely on embeddings extracted from social media. In particular, we use a combination of embeddings built on the user-to-user mention graph, the user-to-hashtag mention graph, and the text of the tweets of the troll accounts. We further explore several possible approaches using label propagation for the distant supervision scenario.\nAs a result of our approach, we improve the classification accuracy by more than 5 percentage points for the supervised learning scenario. The distant supervision scenario has not previously been considered in the literature, and is one of the main contributions of the paper. We show that even by hiding the labels from the ML algorithm, we can recover 78.5% of the correct labels.\nThe contributions of this paper can be summarized as follows:\nWe predict the political role of Internet trolls (left, news feed, right) in a realistic, unsupervised scenario, where labels for the trolls are not available, and which has not been explored in the literature before.\nWe propose a novel distant supervision approach for this scenario, based on graph embeddings, BERT, and label propagation, which projects the more-commonly-available labels for news media onto the trolls who cited these media.\nWe improve over the state of the art in the traditional, fully supervised setting, where training labels are available.\nWe show that even by hiding the labels from the ML algorithm, we can recover 78.5% of the correct labels",

In the underfitting regime (left) performance is sharply lower, in the overfitting regime (right) performance decays slowly, with best performance somewhere in the middle. With regards to IRM: Short answer: The apparent discrepancy is not due to MLP vs ResNet and we do not contradict the prior work. We now include a version of IRM that is tuned to perform closer to ERM by reducing its regularisation strength. Long answer:It’s important to note that these models are run without careful hyperparameter tuning in Fig 2. Depending on hyperparameters, models will achieve different complexities (e.g., as we showed in Fig 1). So the specific placement of any given model (such as IRM, ERM, etc) on the graph will depend on hyperparameter choice. Our point is not about the absolute position of any given model, but the fact that when complexity is allowed to vary by any means (due to regulariser strength, training iterations, choice of ERM vs IRM vs REX etc), the resulting complexity (x-axis) determines the performance (y-axis).",
        "evidence": "Our experiment in Section 4.1 showed that linear models exhibit a very clean trade-off between complexity and generalization. However there are many subtle factors that influence effective model complexity in neural networks besides architecture: learning rate, learning rate schedule, weight decay, early stopping, etc; and the repeatably of learning is hampered by non-convexity, stochastic initialization, and stochastic mini-batches, etc. The previous evaluation study of attempted some degree of control over these factors for state of the art neural DG methods by applying a common hyperparameter search strategy that aimed to find the best tuning (cf: Fig) for each competitor. They nevertheless found existing methods to perform unreliably. Our conjecture is that the number of seed samples (3) and hyper-parameter search trials (20) used was far too few to reliably tune the deep networks evaluated, and therefore the tuning of each model was inaccurate and performance estimates unreliable. Since dense and accurate hyper-parameter tuning for neural networks is more challenging than our linear models in Section 4.1, we take a different approach. Rather than trying to control complexity directly, we take trained DomainBed methods and measure their complexity retrospectively.\nSetup To ensure that complexity can be measured accurately, we work with 2-layer MLPs. Specifically, we take fixed ImageNet pre-trained ResNet-18 features, and feed them to MLPs, which are then trained using the DomainBed framework. 2-layer MLPs are sufficient to instantiate many of the state of the art DG algorithms in DomainBed. We train and compare ERM, CORAL, Mixup , MMD, RSC, SD, VRex, and IRM with two hyperparameter choices. We also report the results of an ERM model, checkpointed at a range of training iterations.\nMeasuring Model Complexity Because we have limited our attention to 2-layer MLPs, we can take advantage of a model capacity metric that is specialised for this class of models. We retrospectively determine the complexity of a trained network using the measure proposed by Neyshabur et al. (), who also use this measure to bound the Rademacher complexity of a 2-layer MLP hypothesis classes. More concretely, the expression used for computing complexity is\nwhere U is the weight matrix of the first layer, U 0 is its random initialisation, and V is the weight matrix of the second layer. We use • F to denote Frobenius norm, and • 2 to indicate the spectral norm. Note that for simplicity we have omitted constant factors that depend only on the architecture and problem setting, and not the learned weights, as we use the same architecture for all methods we investigate.\nThe results in Figure summarise the trade-off between measured model complexity (xaxis), and held-out domain test accuracy (y-axis), averaged over all choices of held out domain for each dataset (See Supplementary for full breakdown across all held-out domains). The top plot compares several of the published neural DG methods implemented in DomainBed. The main message of the top plot is that results are consistent with the hypothesis that the resulting complexity of the models trained by various DG methods is a key factor in determining domain generalisation accuracy (compare Fig. with the clean result for linear where models we are able to intervene and control complexity directly in Fig.)-thus explaining the previously erratic behaviour observed in domain-bed.\nTo provide a different view of the same issue, the bottom plot reports a vanilla untuned ERM model check-pointed every 300 training iterations between (up to a total of 15,000) but expressed in the same complexity units as above. Because neural models can gain complexity with iterations (see, e.g.,;) we also see typical overfitting-underfitting trade-off curves. This shows that, as expected, proper choice of early stopping criterion is important. It also shows that over a similar dynamic range of complexity (0.5-3), ERM (below) and alternative models (above) span a similar dynamic range of accuracy (e.g., 6% for PACS). This suggests that complexity, as controlled by whatever mechanism, is a key determinant of DG performance.\nHow Do DG Models Control Complexity? By introducing different modifications to standard ERM, DG models explicitly or implicitly modify the bias and variance of the function class to be learned. highlight neural models as being dependent on learning rate, batch size, dropout rate, and weight decay; with other factors being choice of optimiser and weight initialiser, etc. For example, higher dropout rate and weight decay tend to reduce complexity, while some other factors influence complexity in a less transparent way. RSC introduce more sophisticated dropout-like mechanisms, which would be expected to reduce complexity. Meanwhile alignment-based methods like CORAL and MMD effectively add auxiliary losses, which will implicitly affect complexity, but are hard to explicitly link to it. Consistency based methods like IRM and VRex penalise loss variance, which also tends to reduce the generalisation gap in the single task case. The specific setting of all the corresponding hyper-parameters (e.g., regulariser strength, dropout rates) influence final model complexity, which we argue is the key determinant of performance.\nFigure 2: Performance of neural networks as a function of their measured model complexity after training using DomainBed (DB). The overall results are consistent with a standard bias-variance trade-off (cf. Fig 1 for linear models): performance depends on how well each model was tuned by DB’s hyper-parameter search procedure. Top: Leave-one-domain-out cross-validation performance of various neural DG algorithms evaluated by DomainBed. Horizontal error bars correspond to the standard deviation of the model complexity measured for each cross-validation iteration. Bottom: Performance of ERM model checkpointed at different training iterations. The central tendency is obtained via fitting a support vector regression model (Shevade et al., 2000) with a 6th order polynomial kernel.",

        "evidence": "Automated deriving discourse relation from free text is a challenging but im-portant problem. The shallow discourse parsing is very useful in the text summariza-tion BIBREF0 , opinion analysis BIBREF1 and natural language generation. Shallow discourse parser is the system of parsing raw text into a set of discourse relations between two adjacent or non-adjacent text spans. Discourse relation is composed of a discourse connective, two arguments of the discourse connective and the sense of the discourse connective. Discourse connective signals the explicit dis-course relation, but in non-explicit discourse relation, a discourse connective is omit-ted. Two arguments of the discourse connective, Arg1 and Arg2, which are the two adjacent or non-adjacent text spans connecting in the discourse relation. The sense of the discourse connective characterizes the nature of the discourse relations. The following discourse relation annotation is taken from the document in the PDTB. Arg1 is shown in italicized, and Arg2 is shown in bold. The discourse connective is underlined.\nThe connective identifier finds the connective word, “unless”. The arguments identifier locates the two arguments of “unless”. The sense classifier labels the dis-course relation. The non-explicit identifier checks all the pair of adjacent sentences. If the non-explicit identifier indentifies the pair of sentences as non-explicit relation, it will label it the relation sense. Though many research work BIBREF2 , BIBREF3 , BIBREF4 are committed to the shallow discourse parsing field, all of them are focus on the subtask of parsing only rather than the whole parsing process. Given all that, a full shallow discourse parser framework is proposed in our paper to turn the free text into discourse relations set. The parser includes connective identifier, arguments identifier, sense classifier and non-explicit identifier, which connects with each other in pipeline. In order to enhance the performance of the parser, the feature-based maximum entropy model approach is adopted in the experiment.

The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan.\n\nColombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the project on May 4, 1904, and opened the canal on August 15, 1914. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for its handover to Panama. After a period of joint American–Panamanian control, the canal was taken over by the Panamanian government in 1999. It is now managed and operated by the government-owned Panama Canal Authority.\n\nCanal locks at each end lift ships up to Gatun Lake, an artificial lake 26 meters (85 ft) above sea level, created to reduce the amount of excavation work required for the canal, and then lower the ships at the other end. The original locks are 33.5 meters (110 ft) wide. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded waterway began commercial operation on June 26, 2016. The new locks allow transit of larger, New Panamax ships.\n\nAnnual traffic has risen from about 1,000 ships in 1914, when the canal opened, to 14,702 vessels in 2008, for a total of 333.7 million Panama Canal/Universal Measurement System (PC/UMS) tons. By 2012, more than 815,000 vessels had passed through the canal. In 2017 it took ships an average of 11.38 hours to pass between the canal's two locks.

The rules are pretty simple, and more importantly, the skill needed to hit functional shots in the game is not very difficult to learn.  Compare it to tennis, where it can take multiple lessons from a professional teacher just to get to a point where you can hit a few good shots.  With pickleball, almost anyone of any age or fitness level can pick up a paddle and be playing a game in just minutes.\n\n- Pickleball culture has tended to be very inclusive.  Many pickleball groups make it a point to be very inclusive of all ages, races and backgrounds.  This often creates a sense of community for players, and makes them more likely to keep playing and invite friends along, thus growing the sport.\n\n- It is a fun way to get in a decent workout.  While not as taxing as, say, tennis, pickleball can be a good workout.  Especially since unlike tennis there is very little downtime.  The pace of games is very quick and involves near constant movement.  The workout is not cardio-intensive, but still it is an easy way to have fun while staying active.",

        "evidence": "This work has applied a multiscale graph partitioning algorithm (Markov Stability) to extract content-based clusters of documents from a textual dataset of healthcare safety incident reports in an unsupervised manner at different levels of resolution. The method uses paragraph vectors to represent the records and obtains an ensuing similarity graph of documents constructed from their content. The framework brings the advantage of multi-resolution algorithms capable of capturing clusters without imposing a priori their number or structure. Since different levels of resolution of the clustering can be found to be relevant, the practitioner can choose the level of description and detail to suit the requirements of a specific task.\nOur a posteriori analysis evaluating the similarity against the hand-coded categories and the intrinsic topic coherence of the clusters showed that the method performed well in recovering meaningful categories. The clusters of content capture topics of medical practice, thus providing complementary information to the externally imposed classification categories. Our analysis shows that some of the most relevant and persistent communities emerge because of their highly homogeneous medical content, although they are not easily mapped to the standardised external categories. This is apparent in the medically-based content clusters associated with Labour ward, Pressure ulcer, Chemotherapy, Radiotherapy, among others, which exemplify the alternative groupings that emerge from free text content.\nThe categories in the top level (Level 1) of the pre-defined classification hierarchy are highly diverse in size (as shown by their number of assigned records), with large groups such as `Patient accident', `Medication', `Clinical assessment', `Documentation', `Admissions/Transfer' or `Infrastructure' alongside small, specific groups such as `Aggressive behaviour', `Patient abuse', `Self-harm' or `Infection control'. Our multi-scale partitioning finds corresponding groups in content across different levels of resolution, providing additional subcategories with medical detail within some of the large categories (as shown in Fig. 4 and S1 ). An area of future research will be to confirm if the categories found by our analysis are consistent with a second level in the hierarchy of external categories (Level 2, around 100 categories) that is used less consistently in hospital settings. The use of content-driven classification of reports could also be important within current efforts by the World Health Organisation (WHO) under the framework for the International Classification for Patient Safety (ICPS) BIBREF48 to establish a set of conceptual categories to monitor, analyse and interpret information to improve patient care.\nOne of the advantages of a free text analytical approach is the provision, in a timely manner, of an intelligible description of incident report categories derived directly from the rich description in the 'words' of the reporter themselves. The insight from analysing the free text entry of the person reporting could play a valuable role and add rich information than would have otherwise been obtained from the existing approach of pre-defined classes. Not only could this improve the current state of play where much of the free text of these reports goes unused, but it avoids the fallacy of assigning incidents to a pre-defined category that, through a lack of granularity, can miss an important opportunity for feedback and learning. The nuanced information and classifications extracted from free text analysis thus suggest a complementary axis to existing approaches to characterise patient safety incident reports.\nCurrently, local incident reporting system are used by hospitals to submit reports to the NRLS and require risk managers to improve data quality of reports, due to errors or uncertainty in categorisation from reporters, before submission. The application of free text analytical approaches, like the one we have presented here, has the potential to free up risk managers time from labour-intensive tasks of classification and correction by human operators, instead for quality improvement activities derived from the intelligence of the data itself. Additionally, the method allows for the discovery of emerging topics or classes of incidents directly from the data when such events do not fit the pre-assigned categories by using projection techniques alongside methods for anomaly and innovation detection.\nIn ongoing work, we are currently examining the use of our characterisation of incident reports to enable comparisons across healthcare organisations and also to monitor their change over time. This part of ongoing research requires the quantification of in-class text similarities and to dynamically manage the embedding of the reports through updates and recalculation of the vector embedding. Improvements in the process of robust graph construction are also part of our future work. Detecting anomalies in the data to decide whether newer topic clusters should be created, or providing online classification suggestions to users based on the text they input are some of the improvements we aim to add in the future to aid with decision support and data collection, and to potentially help fine-tune some of the predefined categories of the external classification.\nAn area of future research will be to confirm if the categories found by our analysis are consistent with a second level in the hierarchy of external categories (Level 2, around 100 categories) that  used less consistently in hospital settings.",

        "question": "Who does Machiavelli believe exemplifies the characteristics of a true prince in The Prince, and why does he hold this belief?",
        "evidence": "",
        "answer": "In Machiavelli’s, The Prince, Machiavelli describes in great detail the extent to which a true prince should rule their state to ensure complete dominance and obedience of its people. He explains the numerous prerequisites and responsibilities of a prince, in which he exemplifies throughout the text through the different figures, in both positive and negative contexts. Throughout The Prince, one figure, who Machiavelli makes clear he has great respect for, highlighting quite frequently, is Cesare Borgia whom he even refers to with the status comparable to the level of God exclaiming that “there was one man who showed glimpses of greatness... that made you think he was sent by God” (26). Similar rhetoric is frequently used to describe Cesare Borgia throughout the text. In search of who truly exemplifies the characterization of “The Prince,” it can generally seem to be Cesare Borgia from the high praise of Machiavelli, but in reality this is not the case. Rather, the title of “The Prince” belongs to a more subtle figure: Ferdinand of Aragon, the King of Spain. This connection is made because of the numerous contradictions Machiavelli makes in praise of Cesare Borgia and other important figures in the text, while many key characteristics of a true prince that Machiavelli speaks of hold without contradiction for Ferdinand.\nMachiavelli exemplifies his teachings through Cesare Borgia’s actions seen in chapter 7 when Cesare Borgia conquered the state of Romagna: immediately crushing the opponent using great cruelty, using a scapegoat to thwart the hatred away from him, and finally killing the scapegoat to create a sense of power and fear within the new states inhabitants. These actions, that explain why he is so highly idolized by Machiavelli, do not go without the fact that other\n \n fundamental characteristics of Cesare Borgia directly contradict Machiavelli's notion of the most dominant prince. A prime example is in how “Cesare Borgia... acquired his state during the ascendancy of his father, and on its decline he lost it” (7). Inheritance obviously requires significantly less effort compared to creating a new principality. Although Cesare Borgia later conquers new principalities, it can be inferred that a rise to power through his fathers fortune was a significant catalyst and does not exemplify virtues of the ideal prince.\nOther figures in the book receive similar praise in leadership abilities, but still lack what qualities compare to the ideal prince. These figures include Pope Julius II, whose power is highlighted by Machiavelli in chapter 13 as being consistent more with fortune rather than virtù in his campaign for conquer, Pope Alexander VI, who although displays cunning ability to bring the catholic empire eventual dominance and power, did so with the initial help of being “granted a title and income from the Roman Catholic Church by his uncle Alonso”.1 Many figures follow the same pattern in that they follow many principles exemplified in The Prince, but of course with so many requisites to be a true prince, these figures do not follow the explicit definition of a prince. One figure however, follows Machiavelli’s points very closely and exemplifies the fundamentals of a true prince in his beginnings, leaving almost no flaws in his rise to becoming a true prince: Ferdinand of Aragon.\nFerdinand’s characteristics lead him to the title of “The Prince” but a core virtù is what truly sets him apart from the other figures: his rise to power. Almost immediately in The Prince, Machiavelli describes the differences between principalities and emphasizes how maintaining a\n1 “Alexander VI.” Encyclopædia Britannica, Encyclopædia Britannica, Inc., www.britannica.com/biography/Alexander-VI.\n \nnew principality is far more difficult than inheritance. This is largely evident in Ferdinand’s rise to leadership in what Machiavelli describes him as “, by fame and glory, from being an insignificant king to be the foremost king in Christendom” (21). Ferdinand demonstrates his cunning deception through his plot for power, “always using religion as a plea, so as to undertake greater schemes,  himself with pious cruelty to driving out and clearing his kingdom of the Moors” (21). Machiavelli marks this never being “a more admirable example, nor one more rare” in which he uses religion as a cloak of invisibility to deceptively conquer states (21). These natural abilities are what make Ferdinand admirable and what separate him from the rest of the figures in the text. This feeling is shared by Machiavelli exclaiming “that his actions have arisen in such a way, one out of the other, that men have never been given time to work steadily against him” (21).",

        "question": "What is used to boost performance?",
        "answer": "User behavioral characteristics.",
        "evidence": "Social media is a very popular way for people to express their opinions publicly and to interact with others online. In aggregation, social media can provide a reflection of public sentiment on various events. Unfortunately, many users engaging online, either on social media, forums or blogs, will often have the risk of being targeted or harassed via abusive language, which may severely impact their online experience and the community in general. The existence of social networking services creates the need for detecting user-generated hateful messages prior to publication. All published text that is used to express hatred towards some particular group with the intention to humiliate its members is considered a hateful message.\nAlthough hate speech is protected under the free speech provisions in the United States, there are other countries, such as Canada, France, United Kingdom, and Germany, where there are laws prohibiting it as being promoting violence or social disorder. Social media services such as Facebook and Twitter have been criticized for not having done enough to prohibit the use of their services for attacking people belonging to some specific race, minority etc. BIBREF0 . They have announced though that they would seek to battle against racism and xenophobia BIBREF1 . Nevertheless, the current solutions deployed by them have attempted to address the problem with manual effort, relying on users to report offensive comments BIBREF2 . This not only requires a huge effort by human annotators, but it also has the risk of applying discrimination under subjective judgment. Moreover, a non-automated task by human annotators would have strong impact on system response times, since a computer-based solution can accomplish this task much faster than humans. The massive rise in the user-generated content in the above social media services, with manual filtering not being scalable, highlights the need for automating the process of on-line hate-speech detection.\nDespite the fact that the majority of the solutions for automated detection of offensive text rely on Natural Language Processing (NLP) approaches, there is lately a tendency towards employing pure machine learning techniques like neural networks for that task. NLP approaches have the drawback of being complex, and to a large extent dependent on the language used in the text. This provides a strong motivation for employing alternative machine learning models for the classification task. Moreover, the majority of the existing automated approaches depend on using pre-trained vectors (e.g. Glove, Word2Vec) as word embeddings to achieve good performance from the classification model. That makes the detection of hatred content unfeasible in cases where users have deliberately obfuscated their offensive terms with short slang words.\nThere is a plethora of unsupervised learning models in the existing literature to deal with hate-speech BIBREF3 , as well as in detecting the sentiment polarity in tweets BIBREF4 . At the same time, the supervised learning approaches have not been explored adequately so far. While the task of sentence classification seems similar to that of sentiment analysis; nevertheless, in hate-speech even negative sentiment could still provide useful insight. Our intuition is that the task of hate-speech detection can be further benefited by the incorporation of other sources of information to be used as features into a supervised learning model. A simple statistical analysis on an existing annotated dataset of tweets by BIBREF5 , can easily reveal the existence of significant correlation between the user tendency in expressing opinions that belong to some offensive class (Racism or Sexism), and the annotation labels associated with that class. More precisely, the correlation coefficient value that describes such user tendency was found to be 0.71 for racism in the above dataset, while that value reached as high as 0.76 for sexism. In our opinion, utilizing such user-oriented behavioural data for reinforcing an existing solution is feasible, because such information is retrieva2ble in real-world use-case scenarios like Twitter. This highlights the need to explore the user features more systematically to further improve the classification accuracy of a supervised learning system.\nOur approach employs a neural network solution composed of multiple Long-Short-Term-Memory (LSTM) based classifiers, and utilizes user behavioral characteristics such as the tendency towards racism or sexism to boost performance. Although our technique is not necessarily revolutionary in terms of the deep learning models used, we show in this paper that it is quite effective.\nOur main contributions are: INLINEFORM0 ) a deep learning architecture for text classification in terms of hateful content, which incorporates features derived form the users' behavioural data, INLINEFORM1 ) a language agnostic solution, due to no-use of pre-trained word embeddings, for detecting hate-speech, INLINEFORM2 ) an experimental evaluation of the model on a Twitter dataset, demonstrating the top performance achieved on the classification task. Special focus is given to investigating how the additional features concerning the users' tendency to utter hate-speech, as expressed by their previous history, could leverage the performance. To the best of our knowledge, there has not been done any previous study on exploring features related to the users tendency in hatred content that used a deep learning model.\nThe rest of the paper is organized as follows. In Section SECREF2 we describe the problem of hate speech in more detail, and we refer to the existing work in the field in Section SECREF3 . In Section SECREF4 we present our proposed model, while in Section SECREF5 we refer to the dataset used, the evaluation tests we performed and we discuss the results received. Finally, in Section SECREF6 we summarize our contributions and discuss the future work.\nOur approach employs a neural network solution composed of multiple Long-Short-Term-Memory (LSTM) based classifiers, and utilizes user behavioral characteristics such as the tendency towards racism or sexism to boost performance.",

We apply a naive Bayesian classifier with character (2, 4 & 6)-grams, word unigram and word bigram features with a hierarchical lexicon based classifier.\nThe naive Bayesian classifier is trained to predict the specific language label of a piece of text, but used to first classify text as belonging to either the Nguni family, the Sotho family, English, Afrikaans, Xitsonga or Tshivenda. The scikit-learn multinomial naive Bayes classifier is used for the implementation with an alpha smoothing value of 0.01 and hashed text features.\nThe lexicon based classifier is then used to predict the specific language within a language group. For the South African languages this is done for the Nguni and Sotho groups. If the lexicon prediction of the specific language has high confidence then its result is used as the final label else the naive Bayesian classifier's specific language prediction is used as the final result. The lexicon is built over all the data and therefore includes the vocabulary from both the training and testing sets.\nThe lexicon based classifier is designed to trade higher precision for lower recall. The proposed implementation is considered confident if the number of words from the winning language is at least one more than the number of words considered to be from the language scored in second place.\nThe stacked classifier is tested against three public LID implementations BIBREF17, BIBREF23, BIBREF8. The LID implementation described in BIBREF17 is available on GitHub and is trained and tested according to a post on the fasttext blog. Character (5-6)-gram features with 16 dimensional vectors worked the best. The implementation discussed in BIBREF23 is available from https://github.com/tomkocmi/LanideNN.

        "question": "Is it better to buy a used car compared to a new car?",
        "evidence": "",
        "answer": "When it comes to buying a car, there are two main options: buying a new car or buying a used car. While both options have their advantages and disadvantages, many people wonder if it is better to buy a used car compared to a new car. In this article, we will explore the pros and cons of buying a used car and help you decide if it is the right choice for you.\n\nPros of Buying a Used Car\n\n1. Lower Price\n\nOne of the biggest advantages of buying a used car is the lower price. Used cars are typically much cheaper than new cars, even if they are only a few years old. This is because new cars lose value quickly as soon as they are driven off the dealership lot. By buying a used car, you can often get a great deal and save thousands of dollars.\n\n2. Lower Depreciation\n\nNew cars depreciate quickly in the first few years of ownership, often losing up to 50% of their value. Used cars, on the other hand, have already gone through this initial depreciation period, so they lose value at a much slower rate. This means that if you decide to sell your used car in a few years, you may not lose as much money as you would with a new car.\n\n3. Lower Insurance Costs\n\nInsurance costs for a used car are typically lower than for a new car. This is because used cars are less expensive, so the insurance company does not have to pay out as much if the car is damaged or totaled. Additionally, if you own the car outright, you may be able to choose a lower level of insurance coverage, which can further reduce your insurance costs.\n\n4. More Options\n\nWhen you buy a used car, you have a wider range of options to choose from than if you were buying a new car. You can choose from different makes, models, and years, and you may be able to find a car with features that are no longer available on new cars. This means that you can find a car that fits your specific needs and preferences.\n\n5. No Hidden Fees\n\nWhen you buy a new car, you may be charged various fees and expenses, such as a destination fee, dealer preparation fee, and advertising fee. With a used car, you do not have to worry about these hidden fees, as they have already been paid by the previous owner.\n\nCons of Buying a Used Car\n\n1. Higher Maintenance Costs\n\nUsed cars may require more maintenance and repairs than new cars, especially if they are older or have high mileage. This can result in higher maintenance costs, which can offset some of the savings you get from buying a used car.\n\n2. Higher Interest Rates\n\nIf you are financing a used car, you may have to pay a higher interest rate than if you were financing a new car. This is because lenders consider used cars to be a greater risk, as they are more likely to need repairs and maintenance.\n\n3. Limited Warranty\n\nMany used cars do not come with a warranty, or the warranty may have expired. This means that if something goes wrong with the car, you will have to pay for the repairs out of pocket. Some dealerships offer extended warranties for used cars, but these can be expensive.\n\n4. Unknown History\n\nWhen you buy a used car, you may not know the full history of the vehicle. The previous owner may not have disclosed all accidents or repairs, and there may be hidden issues that only become apparent after you have purchased the car.\n\n5. Less Advanced Features\n\nUsed cars may not have the latest technology and safety features that are available on new cars. This can be a disadvantage if you are looking for a car with advanced features, such as a backup camera or lane departure warning.\n\nConclusion\n\nBuying a used car can be a great option for many people, as it offers a lower price, slower depreciation, lower insurance costs, more options, and no hidden fees. However, there are also some disadvantages to buying a used car, such as higher maintenance costs, limited warranty, unknown history, higher interest rates, and less advanced features. Ultimately, the decision to buy a used car or a new car depends on your personal preferences and budget.",

        "question": "Perhaps providing the evidence of Loshchilov & Hutter (2018)'s AdamW algorithm increasing overparameterization would strengthen the anecdote at the end of S2.3?",
        "answer": "Additional results and analysis for using AdamW algorithm are added to Section 3.2 to show that the AdamW algorithm may product less efficient networks. Additional analysis of the overfitting issue is also provided in the Appendix.",
        "evidence": "We first conduct experiments on the MNIST dataset using the LeNet-300-100 and LeNet-5 architectures. In Figure (left), the distribution of weights when training with LLR representation is compared with the case of softmax normalization. Using LLR representation yields a better distribution of weights -the probability of small weights around zero is higher and these weights can be pruned with less impact on the performance. Furthermore, weight decaying can push the weights aggressively towards zero as shown in Figure (right). While softmax normalization primarily affects output layers, the ReLU function may cause overfitting in all layers. Therefore, the effect of weight decaying is more prominent and effective as shown in Figure. This observation is consistent with the analysis and hypotheses from Section 2. Figure shows the trade-off curves for test errors vs. total number of effective parameters for all experiment results on the MNIST dataset. Each curve represents 20 trained networks with the same training settings, each point represents the average total number of weights and average top-1 errors of the pruned networks for each of the 10 different pruning settings. We can see that using LLR representation instead of softmax normalization can reduce the total number of parameters for the same accuracy requirement. Using weight decaying also significantly improve the efficiency of the trained networks. Using both methods yields the most efficient neural networks with better performance than the ones using the iterative pruning approach from, as shown in  We found that the AdamW optimizer with weight decaying may increase training accuracy by increasing overfitting and yield less efficient networks, as demonstrated in Figure. Compared with previous results, the optimal pruned model sizes are dramatically increased and using weight decaying does not improve the efficiency of trained networks.  Therefore, the trade-off curves can be used to judge the efficiency of trained networks. Curves closer to the bottom-left region on the figure represent more efficient networks. Both ResNet and DenseNet architectures show similar trends in terms of efficiency. The trade-off curves for the same architecture with different initial model sizes seem to be bounded by a single theoretical curve. In the energy efficient region with small number of parameters, the error rate goes down rapidly with a small increase in the number of parameters; while in the high accuracy region, small increases in accuracy require exponentially increasing numbers of parameters. In this regard, the ResNet-32 and the DenseNet-60 architectures may offer better alternative trade-offs in efficiency. For all experiments using either softmax normalization or LLR representation, the same weight-decaying settings are used. In terms of efficiency trade-offs, we see a similar trend as before: linear increase in accuracy tends to require exponential increase in network capacity. We notice that the difference between softmax normalization and LLR representation is less prominent for the DenseNet architecture. One possible reason is that the BSP loss function is not yet fully optimized for the DenseNet architecture. Another possible reason is that the effects of weight decaying are more prominent than softmax normalization for the DenseNet architecture with larger initial model sizes.\nWe found that the AdamW optimizer with weight decaying may increase training accuracy by increasing overfitting and yield less efficient networks, as demonstrated in Figure 3. Compared with previous results, the optimal pruned model sizes are dramatically increased and using weight decaying does not improve the efficiency of trained networks.****For DenseNet-60 with less than 90K parameters, the performance is comparable to ResNet-56 with 200K parameters. Therefore, overfitting issues with the DenseNet architecture are less prominent than the ResNet architecture. Figure 7 summarize the efficiency trade-offs for both ResNet and DenseNet architectures. Compared with ResNet architecture, the initial DenseNet model sizes are larger, the effects of weight decaying are more prominent than the softmax normalization, and the difference between softmax normalization and LLR representation for DenseNet is smaller.",

        "evidence": "With the growth of the internet in the last decades, users are faced with an increasing amount of information and have to find ways to summarize it. However, producing summaries in a multi-document setting is a challenging task; the language used to display the same information in a sentence can vary significantly, making it difficult for summarization models to capture. Thus large corpora are needed to develop efficient models. There exist two types of summarization: extractive and abstractive. Extractive summarization outputs summaries in two steps, namely via sentence ranking, where an importance score is assigned to each sentence, and via the subsequent sentence selection, where the most appropriate sentence is chosen. In abstractive summarization, summaries are generated word by word auto-regressively, using sequence-to-sequence or language models. Given the complexity of multi-document summarization and the lack of datasets, most researchers use extractive summarization and rely on hand-crafted features or additional annotated data, both needing human expertise.\nTo our knowledge, wiki2018 is the only work that has proposed a large dataset for multi-document summarization. By considering Wikipedia entries as a collection of summaries on various topics given by their title (e.g., Machine Learning, Stephen King), they create a dataset of significant size, where the lead section of an article is defined as the reference summary and input documents are a mixture of pages obtained from the article's reference section and a search engine. While this approach benefits from the large number of Wikipedia articles, in many cases, articles contain only a few references that tend to be of the desired high quality, and most input documents end up being obtained via a search engine, which results in noisy data. Moreover, at testing time no references are provided, as they have to be provided by human contributors. wiki2018 showed that in this case, generated summaries based on search engine results alone are of poor quality and cannot be used.\nIn contrast, we propose a novel domain-specific dataset containing $14\\,652$ samples, based on professional video game reviews obtained via Metacritic and gameplay sections from Wikipedia. By using Metacritic reviews in addition to Wikipedia articles, we benefit from a number of factors. First, the set of aspects used to assess a game is limited and consequently, reviews share redundancy. Second, because they are written by professional journalists, reviews tend to be in-depth and of high-quality. Additionally, when a video game is released, journalists have an incentive to write a complete review and publish it online as soon as possible to draw the attention of potential customers and increase the revenue of their website BIBREF0. Therefore, several reviews for the same product become quickly available and the first version of the corresponding Wikipedia page is usually made available shortly after. Lastly, reviews and Wikipedia pages are available in multiple languages, which opens up the possibility for multilingual multi-document summarization.\nIn contrast, we propose a novel domain-specific dataset containing $14\\,652$ samples, based on professional video game reviews obtained via Metacritic and gameplay sections from Wikipedia.",

Experimental results on the Penn Treebank BIBREF13 demonstrate that our approach improves the basic HMM and DMV by a large margin, leading to the state-of-the-art results on POS induction, and state-of-the-art results on unsupervised dependency parsing in the difficult training scenario where neither gold POS annotation nor punctuation-based constraints are available.\n\nBy choosing an invertible neural network as our non-linear projector, and then parameterizing our model in terms of the projection’s inverse, we are able to derive tractable exact inference and marginal likelihood computation procedures so long as inference is tractable in the underlying syntax model.",

In the Internet era, thanks to the mechanism of sharing in social networks, propaganda campaigns have the potential of reaching very large audiences BIBREF0, BIBREF1, BIBREF2.\nPropagandist news articles use specific techniques to convey their message, such as whataboutism, red Herring, and name calling, among many others (cf. Section SECREF3). Whereas proving intent is not easy, we can analyse the language of a claim/article and look for the use of specific propaganda techniques. Going at this fine-grained level can yield more reliable systems and it also makes it possible to explain to the user why an article was judged as propagandist by an automatic system.\nWith this in mind, we organised the shared task on fine-grained propaganda detection at the NLP4IF@EMNLP-IJCNLP 2019 workshop. The task is based on a corpus of news articles annotated with an inventory of 18 propagandist techniques at the fragment level. We hope that the corpus would raise interest outside of the community of researchers studying propaganda. For example, the techniques related to fallacies and the ones relying on emotions might provide a novel setting for researchers interested in Argumentation and Sentiment Analysis.\nWith this in mind, we organised the shared task on fine-grained propaganda detection at the NLP4IF@EMNLP-IJCNLP 2019 workshop.",

        "evidence": "The race and gender bias evaluation was carried out on the output of the 219 automatic systems that participated in SemEval-2018 Task 1: Affect in Tweets BIBREF5 . The shared task included five subtasks on inferring the affectual state of a person from their tweet: 1. emotion intensity regression, 2. emotion intensity ordinal classification, 3. valence (sentiment) regression, 4. valence ordinal classification, and 5. emotion classification. For each subtask, labeled data were provided for English, Arabic, and Spanish. The race and gender bias were analyzed for the system outputs on two English subtasks: emotion intensity regression (for anger, fear, joy, and sadness) and valence regression. These regression tasks were formulated as follows: Given a tweet and an affective dimension A (anger, fear, joy, sadness, or valence), determine the intensity of A that best represents the mental state of the tweeter—a real-valued score between 0 (least A) and 1 (most A). Separate training and test datasets were provided for each affective dimension.\nTraining sets included tweets along with gold intensity scores. Two test sets were provided for each task: 1. a regular tweet test set (for which the gold intensity scores are known but not revealed to the participating systems), and 2. the Equity Evaluation Corpus (for which no gold intensity labels exist). Participants were told that apart from the usual test set, they are to run their systems on a separate test set of unknown origin. The participants were instructed to train their system on the tweets training sets provided, and that they could use any other resources they may find or create. They were to run the same final system on the two test sets. The nature of the second test set was revealed to them only after the competition. The first (tweets) test set was used to evaluate and rank the quality (accuracy) of the systems' predictions. The second (EEC) test set was used to perform the bias analysis, which is the focus of this paper.\nSystems: Fifty teams submitted their system outputs to one or more of the five emotion intensity regression tasks (for anger, fear, joy, sadness, and valence), resulting in 219 submissions in total. Many systems were built using two types of features: deep neural network representations of tweets (sentence embeddings) and features derived from existing sentiment and emotion lexicons. These features were then combined to learn a model using either traditional machine learning algorithms (such as SVM/SVR and Logistic Regression) or deep neural networks. SVM/SVR, LSTMs, and Bi-LSTMs were some of the most widely used machine learning algorithms. The sentence embeddings were obtained by training a neural network on the provided training data, a distant supervision corpus (e.g., AIT2018 Distant Supervision Corpus that has tweets with emotion-related query terms), sentiment-labeled tweet corpora (e.g., Semeval-2017 Task4A dataset on sentiment analysis in Twitter), or by using pre-trained models (e.g., DeepMoji BIBREF20 , Skip thoughts BIBREF21 ). The lexicon features were often derived from the NRC emotion and sentiment lexicons BIBREF22 , BIBREF23 , BIBREF24 , AFINN BIBREF25 , and Bing Liu Lexicon BIBREF26 .\nWe provided a baseline SVM system trained using word unigrams as features on the training data (SVM-Unigrams). This system is also included in the current analysis.\nMeasuring bias: To examine gender bias, we compared each system's predicted scores on the EEC sentence pairs as follows:\n\nThus, eleven pairs of scores (ten pairs of scores from ten noun phrase pairs and one pair of scores from the averages on name subsets) were examined for each template–emotion word instantiation. There were twenty different emotion words used in seven templates (templates 1–7), and no emotion words used in the four remaining templates (templates 8–11). In total, INLINEFORM0 pairs of scores were compared.\nSimilarly, to examine race bias, we compared pairs of system predicted scores as follows:\n\nThus, one pair of scores was examined for each template–emotion word instantiation. In total, INLINEFORM0 pairs of scores were compared.\nFor each system, we calculated the paired two sample t-test to determine whether the mean difference between the two sets of scores (across the two races and across the two genders) is significant. We set the significance level to 0.05. However, since we performed 438 assessments (219 submissions evaluated for biases in both gender and race), we applied Bonferroni correction. The null hypothesis that the true mean difference between the paired samples was zero was rejected if the calculated p-value fell below INLINEFORM0 .\nTo examine gender bias, we compared each system’s predicted scores on the EEC sentence pairs as follows:  • We compared the predicted intensity score for a sentence generated from a template using a female noun phrase (e.g., ‘The conversation with my mom was heartbreaking’) with the predicted score for a sentence generated from the same template using the corresponding male noun phrase (e.g., ‘The conversation with my dad was heartbreaking’).  • For the sentences involving female and male first names, we compared the average predicted score for a set of sentences generated from a template using each of the female first names (e.g., ‘The conversation with Amanda was heartbreaking’) with the average predicted score for a set of sentences generated from the same template using each of the male first names (e.g., ‘The conversation with Alonzo was heartbreaking’).",

        "question": "How can I improve my sleep?",
        "evidence": "",
        "answer": "There are a number of variables that can help you improve your sleep.  It is important to try different recommendations and see which ones will have the biggest impact for you.  Sleep is the foundation of our mental and physical health and performance in all endeavors. \n\n1) View sunlight by going outside within 30-60 minutes of waking. Do that again in the late afternoon, prior to sunset. If you wake up before the sun is out and you want to be awake, turn on artificial lights and then go outside once the sun rises.\nOn bright cloudless days: view morning and afternoon sun for 10 min; cloudy days: 20 min; very overcast days 30-60 min. If you live someplace with very minimal light, consider an artificial daytime simulator source.\nDon’t wear sunglasses for this practice if you safely can, but contact lenses and eyeglasses are fine.\nNo, you don’t have to look directly at the sun, and never look at ANY light so bright it is painful to view! That said, you can’t wear a brimmed hat, sunglasses and remain in the shade and expect to “wake up” your circadian clock.\n\n2) Wake up at the same time each day and go to sleep when you first start to feel sleepy. Pushing through the sleepy late evening feeling and going to sleep too late is one reason people wake at 3 am and can’t fall back asleep.\n\n3) Avoid caffeine within 8-10 hours of bedtime. \n\n4) Avoid viewing bright lights—especially bright overhead lights between 10 pm and 4 am. Here is a simple rule: only use as much artificial lighting as is necessary for you to remain and move about safely at night. Blue blockers can help a bit at night but still dim the lights. Viewing bright lights of all colors are a problem for your circadian system. Candlelight and moonlight are fine. \n\n5) Limit daytime naps to less than 90 min, or don’t nap at all. \n\n6) If you wake up in the middle of the night (which, by the way, is normal to do once or so each night) but you can’t fall back asleep, consider doing an NSDR protocol when you wake up. \n\n7) Keep the room you sleep in cool and dark and layer on blankets that you can remove.\nYour body needs to drop in temperature by 1-3 degrees to fall and stay asleep effectively. Body temperature increases are one reason you wake up. Thus, keep your room cool and remove blankets as needed. If it’s too hot you would have to use a cooling device and that’s harder than simply tossing off blankets if you get too warm.\n\n8) Drinking alcohol messes up your sleep. As do most sleep medications.\n\n9) Kids have changing sleep needs over time. Adjust accordingly.\nTeens might be night owls at 15 but become “morning people” as they age or need 6 hours a night in summer and 7-8 in winter. It will vary.",

        "evidence": "",
        "answer": "There have been recent improvements in RV electrical systems. At the core, RVs run off “house batteries”, or large batteries that power the RV portion of the vehicle. There are several types of batteries available, and several ways of powering these batteries. The two main types of batteries are lead acid, and lithium. Lithium batteries are newer technology and will not be found in older RVs unless retrofitted. Lithium batteries have a larger charge capacity and can discharge safely further than lead acid batteries. However, lead acid batteries are cheaper. There are several ways of charging these batteries. The most common is a plug that provides either 30A or 50A of power, depending on the RV size. Most RVs also have generators, but generators are noisy and require either gas or diesel to run. Some RVs with lithium batteries (or more rarely, lead acid), have a second alternator installed that charges the batteries while driving. Finally, solar power is a popular option. Solar power is completely quiet and renewable, but can be expensive to install and is slower to charge batteries. Most RVs have a combination of the above, and consumers choose the system that best fits their lifestyle.",

While recuperating, he discovered that he has the power to paralyze with his gaze. Seeking revenge, Saint assumed the guise of the vigilante the Needle. Armed with a yard-long needle, the mute villain attacked young men on the streets at night, sewing their mouths shut. After victimizing S.H.I.E.L.D. agent Jerry Hunt, the Needle incurred the wrath of Spider-Woman, the agent's girlfriend, and she took him out with a close-range venom blast.

        "evidence": "Extractive multi-document summarization (MDS) aims to summarize a collection of documents by selecting a small number of sentences that represent the original content appropriately. Typical objectives for assembling a summary include information coverage and non-redundancy. A wide variety of methods have been introduced to approach MDS.\nMany approaches are based on sentence ranking, i.e. assigning each sentence a score that indicates how well the sentence summarizes the input BIBREF0 , BIBREF1 , BIBREF2 . A summary is created by selecting the top entries of the ranked list of sentences. Since the sentences are often treated separately, these models might allow redundancy in the summary. Therefore, they are often extended by an anti-redundancy filter while de-queuing ranked sentence lists.\nOther approaches work at summary-level rather than sentence-level and aim to optimize functions of sets of sentences to find good summaries, such as KL-divergence between probability distributions BIBREF3 or submodular functions that represent coverage, diversity, etc. BIBREF4 \nThe centroid-based model belongs to the former group: it represents sentences as bag-of-word (BOW) vectors with TF-IDF weighting and uses a centroid of these vectors to represent the whole document collection BIBREF5 . The sentences are ranked by their cosine similarity to the centroid vector. This method is often found as a baseline in evaluations where it usually is outperformed BIBREF0 , BIBREF6 .\nThis baseline can easily be adapted to work at the summary-level instead the sentence level. This is done by representing a summary as the centroid of its sentence vectors and maximizing the similarity between the summary centroid and the centroid of the document collection. A simple greedy algorithm is used to find the best summary under a length constraint.\nIn order to keep the method efficient, we outline different methods to select a small number of candidate sentences from each document in the input collection before constructing the summary.\nWe test these modifications on the DUC2004 dataset for multi-document summarization. The results show an improvement of Rouge scores over the original centroid method. The performance is on par with state-of-the-art methods which shows that the similarity between a summary centroid and the input centroid is a well-suited function for global summary optimization.\nThe summarization approach presented in this paper is fast, unsupervised and simple to implement. Nevertheless, it performs as well as more complex state-of-the-art approaches in terms of Rouge scores on the DUC2004 dataset. It can be used as a strong baseline for future research or as a fast and easy-to-deploy summarization tool.\nThe results show an improvement of Rouge scores over the original centroid method.",

Schabowski was joined by Minister of Foreign Trade Gerhard Beil and Central Committee members Helga Labs and Manfred Banaschak.: 352 \n\nSchabowski had not been involved in the discussions about the new regulations and had not been fully updated. Shortly before the press conference, he was handed a note from Krenz announcing the changes, but given no further instructions on how to handle the information. The text stipulated that East German citizens could apply for permission to travel abroad without having to meet the previous requirements for those trips, and also allowed for permanent emigration between all border crossings—including those between East and West Berlin.\n\nAt 18:53, near the end of the press conference, ANSA's Riccardo Ehrman asked if the draft travel law of 6 November was a mistake. Schabowski gave a confusing answer that asserted it was necessary because West Germany had exhausted its capacity to accept fleeing East Germans, then remembered the note he had been given and added that a new regulation had been drafted to allow permanent emigration at any border crossing. This caused a stir in the room; amid several questions at once, Schabowski expressed surprise that the reporters had not yet seen this regulation, and started reading from the note. After this, a reporter, either Ehrman or Bild-Zeitung reporter Peter Brinkmann, both of whom were sitting in the front row at the press conference, asked when the regulations would take effect. After a few seconds' hesitation, Schabowski replied, \"As far as I know, it takes effect immediately, without delay\" (German: Das tritt nach meiner Kenntnis ... ist das sofort ... unverzüglich).: 352  This was an apparent assumption based on the note's opening paragraph; as Beil attempted to interject that it was up to the Council of Ministers to decide when it took effect, Schabowski proceeded to read this clause, which stated it was in effect until a law on the matter was passed by the Volkskammer. Crucially, a journalist then asked if the regulation also applied to the crossings to West Berlin. Schabowski shrugged and read item 3 of the note, which confirmed that it did.\n\nAfter this exchange, Daniel Johnson of The Daily Telegraph asked what this law meant for the Berlin Wall. Schabowski sat frozen before giving a rambling statement about the Wall being tied to the larger disarmament question. He then ended the press conference promptly at 19:00 as journalists hurried from the room.\n\nAfter the press conference, Schabowski sat for an interview with NBC News anchor Tom Brokaw in which he repeated that East Germans would be able to emigrate through the border and the regulations would go into effect immediately.",

The note specified that East German citizens could apply for permission to travel abroad, and permanent emigration between all border crossings—including those between East and West Berlin – would be allowed.\nAt 6:53 pm, near the end of the press conference, when asked if the draft travel law of 6 November was a mistake, Schabowski gave a confusing answer that it was necessary because West Germany had exhausted its capacity to accept fleeing East Germans, then remembered the note he had been handed and went on to add that a new regulation had been drafted to allow permanent emigration at any border crossing. This caused a stir in the room, several questions came flying at once. When asked when the regulations would take effect, Schabowski replied hesitantly, \"As far as I know, it takes effect immediately, without delay\". And after some confused interjections between party members, when asked what this law meant for the Berlin Wall, Schabowski froze for a few moments, before blurting out something to the effect of the Wall being tied to the larger disarmament question. He then ended the press conference promptly at 7 pm, as journalists hurried out of the room.",

        "question": "What can we consider language variety identification as?",
        "answer": "We can consider language variety identification as a double problem of text classification and author profiling.",
        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nDue to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.",

During the endgame, stalemate is a resource that can enable the player with the inferior position to draw the game rather than lose. In more complex positions, stalemate is much rarer, usually taking the form of a swindle that succeeds only if the superior side is inattentive.[citation needed] Stalemate is also a common theme in endgame studies and other chess problems.\n\nThe outcome of a stalemate was standardized as a draw in the 19th century. Before this standardization, its treatment varied widely, including being deemed a win for the stalemating player, a half-win for that player, or a loss for that player; not being permitted; and resulting in the stalemated player missing a turn. Stalemate rules vary in other games of the chess family.",

        "evidence": "",
        "answer": "A-frame can occur due to many reasons, this includes improper boot setup, for example, the cuff alignment is incorrect, or technique issues. It is best to consult an experienced boot fitter to ensure the boot is set up correctly. Once you've ensured the boot is set up correctly, it is likely a technique issue. A common cause of A-frame is a result of rotating the outside knee inside more than the inside knee, and this can happen due to wider skis or wanting to create a bigger edge angle. Ideally, we should avoid over-rotating the knee inside as this creates a weaker position and instead rely on moving the hip and upper body into the inside of the turn to create a bigger edge angle and try to keep the outside leg relatively straight.\n\nA good exercise to practice this is the T-drill, where you try to make sure your outside leg is as straight as possible and create edge angle by leaning your whole body into the turn, you'll need to shorten your inside leg by bringing your need to your chest, which will then still allow you to balance mostly on your straight downhill leg.",

When his mother Saki dies, Kōsei has a mental breakdown while performing at a piano recital; this results in him becoming unable to hear the sound of his piano, even though his hearing is otherwise unaffected.\n\nTwo years later, Kōsei has not touched the piano and views the world in monochrome. He does not focus on excelling in any activities and often spends time with his friends Tsubaki Sawabe and Ryōta Watari. Kōsei meets Kaori Miyazono, an audacious, free-spirited, fourteen-year-old violinist whose playing style reflects her manic personality. Kaori helps Kōsei return to playing the piano, and shows him his playing style can be free and groundbreaking. As Kaori continues to uplift Kōsei's spirits, he quickly realizes he loves her, although she seems to only be interested in Ryōta.\n\nDuring a performance, Kaori, who later explains that she is anemic and needs routine testing, collapses and is hospitalized. She is later diagnosed with Aplastic Anemia. She invites Kōsei to play with her at a gala but she does not arrive. Her health deteriorates and she becomes dejected. Kōsei plays a duet with a friend, which motivates Kaori to attempt a risky and potentially deadly surgery so she may possibly play with Kosei once more. While playing in the finals of the Eastern Japan Piano Competition, Kōsei sees Kaori's spirit accompanying him and realizes she has died during the surgery.\n\nAt her funeral, Kaori's parents give Kōsei a letter from Kaori that reveals she was aware of her impending death and became more free-spirited, both as a person and in her music, so she would not take her regrets to Heaven. She confesses she had been in love with Kōsei's piano playing since watching him perform at a concert when she was five. This inspired her to play the violin so she could play with him one day. Kaori fabricated her feelings towards Ryōta so she could get closer to Kōsei without hurting Tsubaki, who harbored affection for Kōsei. She then confesses her love for him. Tsubaki comforts Kōsei and tells him she will be by his side. Kaori also leaves behind a picture of herself as a child, coming back from the concert that inspired her, with Kōsei in the background. Kōsei later frames this picture.",

For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nFor an ever increasing spectrum of applications (e.g., medical text analysis, opinion mining, sentiment analysis, social media text analysis, customer intelligence, fraud analytics etc.) mining and analysis of unstructured natural language text data is necessary [1, 2, 3].",

We thus enhance the quality of the synthetic examples of the source-originated Fr*-De data by further training its mother translation model (En $\\rightarrow $ Fr). As illustrated in Figure 2 , with the target-originated Fr-De* corpus being fixed, the quality of the models trained with the source-originated Fr*-De data and PSEUDOmix increases in proportion to the quality of the mother model for the Fr*-De corpus. Eventually, PSEUDOmix shows the highest BLEU, outperforming both Fr*-De and Fr-De* data. The results indicate that the benefit of the proposed mixing approach becomes much more evident when the quality gap between the source- and target-originated synthetic data is within a certain range.\nAs presented in Table 6 , we observe that fine-tuning using ground truth parallel data brings substantial improvements in the translation qualities of all NMT models. Among all fine-tuned models, PSEUDOmix shows the best performance in all experiments. This is particularly encouraging for the case of De $\\rightarrow $ Fr, where PSEUDOmix reported lower BLEU than the Fr-De* data before it was fine-tuned. Even in the case where PSEUDOmix shows comparable results with other synthetic corpora in the Pseudo Only scenario, it shows higher improvements in the translation quality when fine-tuned with the real parallel data. These results clearly demonstrate the strengths of the proposed PSEUDOmix, which indicate both competitive translation quality by itself and relatively higher potential improvement as a result of the refinement using ground truth parallel corpora.\nWhile the mixing strategy compensates for most of the gap between the Fr-De* and the Fr*-De (3.01 $\\rightarrow $ 0.17) in the De $\\rightarrow $ Fr case, the resulting PSEUDOmix still shows lower BLEU than the target-originated Fr-De* corpus.

Once the seed dictionary is obtained, the two-step iterative self-learning procedure (C2) takes place: 1) a dictionary $D^{(k)}$ is first used to learn the joint space $\\mathbf {Y}^{(k)} = \\mathbf {X{W}}^{(k)}_x \\cup \\mathbf {Z{W}}^{(k)}_z$ ; 2) the nearest neighbours in $\\mathbf {Y}^{(k)}$ then form the new dictionary $D^{(k+1)}$ .

On March 23, 1998, the owners of all 29 NBA teams voted 27–2 to reopen the league's collective bargaining agreement, seeking changes to the league's salary cap system, and a ceiling on individual player salaries. The National Basketball Players Association (NBPA) opposed to the owners' plan, and wanted raises for players who earned the league's minimum salary. After both sides failed to reach an agreement, the owners called for a lockout, which began on July 1, 1998, putting a hold on all team trades, free agent signings and training camp workouts, and cancelling many NBA regular season and preseason games. Due to the lockout, the NBA All-Star Game, which was scheduled to be played in Philadelphia on February 14, 1999, was also cancelled. However, on January 6, 1999, NBA commissioner David Stern, and NBPA director Billy Hunter finally reached an agreement to end the lockout. The deal was approved by both the players and owners, and was signed on January 20, ending the lockout after 204 days.

        "question": "Summarize the main milestones of an NBA season",
        "evidence": "Following the summer break, teams begin training camps in late September. Training camps allow the coaching staff to evaluate players (especially rookies), scout the team's strengths and weaknesses, prepare the players for the rigorous regular season and determine the 12-man active roster (and a 3-man inactive list) with which they will begin the regular season. Teams have the ability to assign players with less than two years of experience to the NBA G League. After training camp, a series of preseason exhibition games are held. Preseason matches are sometimes held in non-NBA cities, both in the United States and overseas. The NBA regular season begins in the last week of October.\n\nDuring the regular season, each team plays 82 games, 41 each home and away. A team faces opponents in its own division four times a year (16 games). Each team plays six of the teams from the other two divisions in its conference four times (24 games), and the remaining four teams three times (12 games). Finally, each team plays all the teams in the other conference twice apiece (30 games). This asymmetrical structure means the strength of schedule will vary between teams (but not as significantly as the NFL or MLB). Over five seasons, each team will have played 80 games against their division (20 games against each opponent, 10 at home, 10 on the road), 180 games against the rest of their conference (18 games against each opponent, 9 at home, 9 on the road), and 150 games against the other conference (10 games against each team, 5 at home, 5 on the road).\n\nThe NBA is also the only league that regularly schedules games on Christmas Day. The league has been playing games regularly on the holiday since 1947, though the first Christmas Day games were not televised until 1983–84. Games played on this day have featured some of the best teams and players. Christmas is also notable for NBA on television, as the holiday is when the first NBA games air on network television each season. Games played on this day have been some of the highest-rated games during a particular season.\n\nIn February, the regular season pauses to celebrate the annual NBA All-Star Game. Fans vote throughout the United States, Canada, and on the Internet, and the top vote-getters in each conference are named captains. Fan votes determine the rest of the allstar starters. Coaches vote to choose the remaining 14 All-Stars. Then, the top vote-getters in each conference draft their own team from a player pool of allstars. The top vote-getter in the league earns first pick and so forth. The player with the best performance during the game is rewarded with a Game MVP award. Other attractions of the All-Star break include the Rising Stars Challenge (originally Rookie Challenge), where the top rookies and second-year players in the NBA play in a 5-on-5 basketball game, with the current format pitting U.S. players against those from the rest of the world; the Skills Challenge, where players compete to finish an obstacle course consisting of shooting, passing, and dribbling in the fastest time; the Three Point Contest, where players compete to score the highest number of three-point field goals in a given time; and the NBA Slam Dunk Contest, where players compete to dunk the ball in the most entertaining way according to the judges. These other attractions have varying names which include the names of the various sponsors who have paid for naming rights.\n\nShortly after the All-Star break is the trade deadline, which is set to fall on the 16th Thursday of the season (usually in February) at 3 pm Eastern Time. After this date, teams are not allowed to exchange players with each other for the remainder of the season, although they may still sign and release players. Major trades are often completed right before the trading deadline, making that day a hectic time for general managers.\n\nAround the middle of April, the regular season ends. It is during this time that voting begins for individual awards, as well as the selection of the honorary, league-wide, postseason teams. The Sixth Man of the Year Award is given to the best player coming off the bench (must have more games coming off the bench than actual games started). The Rookie of the Year Award is awarded to the most outstanding first-year player. The Most Improved Player Award is awarded to the player who is deemed to have shown the most improvement from the previous season. The Defensive Player of the Year Award is awarded to the league's best defender. The Coach of the Year Award is awarded to the coach that has made the most positive difference to a team. The Most Valuable Player Award is given to the player deemed the most valuable for (his team) that season. Additionally, Sporting News awards an unofficial (but widely recognized) Executive of the Year Award to the general manager who is adjudged to have performed the best job for the benefit of his franchise.\n\nThe postseason teams are the All-NBA Team, the All-Defensive Team, and the All-Rookie Team; each consists of five players. There are three All-NBA teams, consisting of the top players at each position, with first-team status being the most desirable. There are two All-Defensive teams, consisting of the top defenders at each position. There are also two All-Rookie teams, consisting of the top first-year players regardless of position.",

        "evidence": "Clustering multi-lingual documents has received much attention in natural language processing. Among approaches not using some form of machine translation, one can mention BIBREF1 , who essentially employ a bilingual dictionary to bring some words in the documents to a language-independent form and then to perform clustering. In the section \"Experiment Design and Evaluation\" we show that our approach based on neural embeddings significantly outperforms their reported results.\n BIBREF2 proposed training joint multi-lingual neural embedding models. Theoretically, this can be used to achieve our aim of language-independent semantic representations for documents. Unfortunately, it demands a large word-aligned parallel corpus. This is not the case with the more recent Trans-gram approach introduced in BIBREF3 , also able to learn multi-lingual models. However, it still needs sentence-aligned corpora to train on (in the size of millions of paired sentences). Large parallel corpora (whether word- or sentence-aligned) are often a scarce resource, especially in the case of under-represented languages.\nThe approach described in this paper takes as an input only comparable monolingual corpora and bilingual dictionaries in the size of several thousand word pairs. Such resources are much easier to find and evaluate. We employ the idea of learning a linear transformation matrix to map or project word embeddings from the semantic space of one language to that of another. This idea was first proposed in BIBREF4 , who applied it to lexical translation between English, Spanish, Czech and Vietnamese. We extend it from continuous representations of single words or collocations to `semantic fingerprints' of documents as a whole.\nWe employ the idea of learning a linear transformation matrix to map or project word embeddings from the semantic space of one language to that of another.

        "evidence": "koehn-knowles:2017:NMT showed that NMT is unable to handle low-resource language pairs as opposed to PBSMT. Transfer learning approaches BIBREF5 , BIBREF6 , BIBREF7 work well when a large helping parallel corpus is available. This restricts one of the source or the target languages to be English which, in our case, is not possible. Approaches involving bi-directional NMT modeling is shown to drastically improve low-resource translation BIBREF11 . However, like most other, this work focuses on translation from and into English.\nRemaining options include (a) unsupervised MT BIBREF12 , BIBREF13 , BIBREF14 , (b) parallel sentence mining from non-parallel or comparable corpora BIBREF15 , BIBREF16 , (c) generating pseudo-parallel data BIBREF17 , and (d) MT based on pivot languages BIBREF10 . The linguistic distance between Japanese and Russian makes it extremely difficult to learn bilingual knowledge, such as bilingual lexicons and bilingual word embeddings. Unsupervised MT is thus not promising yet, due to its heavy reliance on accurate bilingual word embeddings. Neither does parallel sentence mining, due to the difficulty of obtaining accurate bilingual lexicons. Pseudo-parallel data can be used to augment existing parallel corpora for training, and previous work has reported that such data generated by so-called back-translation can substantially improve the quality of NMT. However, this approach requires base MT systems that can generate somewhat accurate translations. It is thus infeasible in our scenario, because we can obtain only a weak system which is the consequence of an extremely low-resource situation. MT based on pivot languages requires large in-domain parallel corpora involving the pivot languages. This technique is thus infeasible, because the in-domain parallel corpora for Ja INLINEFORM0 En and Ru INLINEFORM1 En pairs are also extremely limited, whereas there are large parallel corpora in other domains. Section SECREF4 empirically confirms the limit of these existing approaches.\nFortunately, there are two useful transfer learning solutions using NMT: (e) multilingual modeling to incorporate multiple language pairs into a single model BIBREF8 and (f) domain adaptation to incorporate out-of-domain data BIBREF9 . In this paper, we explore a novel method involving step-wise fine-tuning to combine these two methods. By improving the translation quality in this way, we can also increase the likelihood of pseudo-parallel data being useful to further improve translation quality.\nFortunately, there are two useful transfer learning solutions using NMT: (e) multilingual modeling to incorporate multiple language pairs into a single model (Johnson et al., 2017) and (f) domain adaptation to incorporate out-of-domain data (Chu et al., 2017).",

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task.",

The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City and the third into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia, near Washington, D.C. The fourth plane was similarly intended to hit a federal government building in D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the global war on terror.\n\nThe first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Center's South Tower was hit by United Airlines Flight 175. Both 110-story skyscrapers collapsed within an hour and forty-one minutes, bringing about the destruction of the remaining five structures in the WTC complex, as well as damaging or destroying various other buildings surrounding the towers. A third flight, American Airlines Flight 77, crashed into the Pentagon at 9:37 a.m., causing a partial collapse. The fourth and final flight, United Airlines Flight 93, flew in the direction of Washington, D.C. Alerted to the previous attacks, the plane's passengers attempted to gain control of the aircraft, but the hijackers ultimately crashed the plane in a field in Stonycreek Township, Pennsylvania, near Shanksville at 10:03 a.m. Investigators determined that Flight 93 target was either the United States Capitol or the White House.\n\nWithin hours of the attacks, the Central Intelligence Agency determined that al-Qaeda was responsible. The United States formally responded by launching the war on terror and invading Afghanistan to depose the Taliban, which had not complied with U.S. demands to expel al-Qaeda from Afghanistan and extradite its leader, Osama bin Laden. The U.S.'s invocation of Article 5 of the North Atlantic Treaty—its only usage to date—called upon allies to fight al-Qaeda. As U.S. and NATO ground forces swept through Afghanistan, bin Laden fled to the White Mountains, where he narrowly avoided capture by U.S.-led forces. Although bin Laden initially denied any involvement, in 2004 he formally claimed responsibility for the attacks. Al-Qaeda's cited motivations included U.S. support of Israel, the presence of U.S. troops in Saudi Arabia, and sanctions against Iraq. After evading capture for almost a decade, bin Laden was killed by the U.S. military on May 2, 2011. U.S. and NATO troops remained in Afghanistan until 2021.\n\nThe attacks resulted in 2,977 non-hijacker fatalities, an indeterminate number of injuries, and substantial long-term health consequences, in addition to at least $10 billion in infrastructure and property damage. It remains the deadliest terrorist attack in human history as well as the single deadliest incident for firefighters and law enforcement officers in U.S. history, with 340 and 72 killed, respectively. The destruction of the World Trade Center and its environs seriously harmed the New York City economy and induced global market shocks. Many other countries strengthened anti-terrorism legislation and expanded their powers of law enforcement and intelligence agencies. Cleanup of the World Trade Center site (colloquially \"Ground Zero\") took eight months and was completed in May 2002, while the Pentagon was repaired within a year. After delays in the design of a replacement complex, the One World Trade Center began construction in November 2006 and opened in November 2014. Memorials to the attacks include the National September 11 Memorial & Museum in New York City, the Pentagon Memorial in Arlington County, Virginia, and the Flight 93 National Memorial at the Pennsylvania crash site.",

That's because, while the experience of driving an EV may feel like a zero-compromise embrace of green energy, the vast industrial network needed to build and power EVs diminishes the halo effect. On the other hand, the fossil fuels that power traditional vehicles are definitely contributing to global warming and leave the world vulnerable to oil shocks and pressure from oil-producing countries. \n\nWhether EVs are better or worse for the environment is still to be determined. But a more insidious trend is the growing size and power of electric vehicles. Smaller vehicles, traveling fewer miles, represents a proven formula for reducing emissions and reversing climate change. But already, we're seeing the advent of electric trucks and SUVs, which are heavier, loaded with bells and whistles so they require more and more power to move people around. Coupled with the problem of drivers feeling like their EV gives them the right to drive as much as they want and you can see a reality emerging where the problem of Americans driving giant gas guzzlers is being replaced with American driving giant, power-sucking EVs.

        "answer": "We will set up the Discussion section and add more detailed discussions.\nAs stated in the paper, we estimate one PNL model by training the corresponding neural networks several times to stabilize results. Therefore, the stabilization of the training is important for not only improving the performance but also reducing the computational cost. One of the typical approaches is to change the optimizer, while there is a trade-off between stability and speed. Another possible option is to add a regularization term to the loss. To use this idea, we need to consider carefully the impact of changing the loss on using its value when comparing models in the sink identification.\nMy main concern is about the numerical comparison. In fact only one single DAG with a few SCMs is considered and the proposed approach compared to the RESIT estimator of ANM and DirectLinGAM. As mentioned above, there seems to be another relevant neural network estimator that could be considered here.\nIn the experiment in section 4.1, we randomly generated 100 linear and nonlinear problems, respectively, as stated in the caption of Table 1. In this procedure, not only causal equations but also DAG structures are generated randomly. Two examples in Fig. 2 are (coincidentally) have the same DAG structure.\nWe apologize for insufficient and misleading expressions. To make it clear, we will add the descriptions in the main text and change the examples in Fig. 2.",
        "evidence": "In this section, we discuss the properties of the proposed method, specifically the computational complexity and the stabilization.\nIn the proposed method, we use neural networks to represent models and estimate them by optimizing their parameters using stochastic gradient descent methods. Since each neural network represents a simple scalar function, it is unnecessary to be a complex design. Therefore, the train-ing time is shorter than the general deep models such as image recognition and language processing.\nOn the other hand, the number of estimations grows exponentially as the number of variables increases. Given n variables, the identification of causal order requires n − 1 iterations. In each iteration, we compare k models for the remaining k variables. Therefore, a total of n + (n − 1) + • • • + 2 = n(n − 1)/2 − 1 model estimations are required, which is the same as RESIT and DirectLiNGAM. Additionally, the proposed method trains one model several times to stabilize results. Consequently, the total number of training becomes t(n(n−1)/2−1), where t is the number of training trials per one model. Similar to the identification of causal order, the pruning procedure also requires an exponential number of estimations. For the worst case, where all the edges will be pruned, a total of t(k(k − 1)/2 − 1) estimations are required for each multi-cause substructure with k cause variables 4 . The number of estimations increases as the ground truth DAG becomes sparse.\nOne effective approach to alleviate the computational time is parallelization. Since all the estimations in one iteration of the identification of causal order can be performed separately, we can reduce the time by parallelizing them. If enough computational resources are available, we can identify the causal order with n − 1 serial iterations. Similarly, the time of the pruning can be reduced by the same manner.

        "question": "Which two data sets did the author use?",
        "answer": "Chinese-English and EnglishFrench.",
        "evidence": "To make the conclusion convincing, we first choose two large-scale datasets that are publicly available, i.e., Chinese-English and English-French. Since English, French, and Chinese all belong to the subject-verb-object (SVO) family, we choose another very different subject-object-verb (SOV) language, Japanese, which might bring some interesting linguistic behaviors in English-Japanese translation.\nFor Chinese-English task, we use WMT17 Chinese-English dataset that consists of $20.6$M sentence pairs. For English-French task, we use WMT14 English-French dataset that comprises $35.5$M sentence pairs. For English-Japanese task, we follow BIBREF17 to use the first two sections of WAT17 English-Japanese dataset that consists of $1.9$M sentence pairs. Following the standard NMT procedure, we adopt the standard byte pair encoding (BPE) BIBREF18 with 32K merge operations for all language pairs. We believe that these datasets are large enough to confirm the rationality and validity of our experimental analyses.\nWe choose the state-of-the-art Transformer BIBREF1 model and the conventional RNN-Search model BIBREF0 as our test bed. We implement the Attribution method based on the Fairseq-py BIBREF19 framework for the above models. All models are trained on the training corpus for 100k steps under the standard settings, which achieve comparable translation results. All the following experiments are conducted on the test dataset, and we estimate the input word importance using the model generated hypotheses.\nIn the following experiments, we compare IG (Attribution) with several black-box methods (i.e., Content, Frequency, Attention) as introduced in Section SECREF8. In Section SECREF21, to ensure that the translation performance decrease attributes to the selected words instead of the perturbation operations, we randomly select the same number of words to perturb (Random), which serves as a baseline. Since there is no ranking for content words, we randomly select a set of content words as important words. To avoid the potential bias introduced by randomness (i.e., Random and Content), we repeat the experiments for 10 times and report the averaged results. We calculate the Attention importance in a similar manner as the Attribution, except that the attention scores use a max operation due to the better performance.\nWe evaluate the effectiveness of estimating word importance by the translation performance decrease. More specifically, unlike the usual way, we measure the decrease of translation performance when perturbing a set of important words that are of top-most word importance in a sentence. The more translation performance degrades, the more important the word is.\nWe use the standard BLEU score as the evaluation metric for translation performance. To make the conclusion more convincing, we conduct experiments on different types of synthetic perturbations (Section SECREF21), as well as different NMT architectures and language pairs (Section SECREF27). In addition, we compare with a supervised erasure method, which requires ground-truth translations for scoring word importance (Section SECREF30).\nIn this experiment, we investigate the effectiveness of word importance estimation methods under different synthetic perturbations. Since the perturbation on text is notoriously hard BIBREF20 due to the semantic shifting problem, in this experiment, we investigate three types of perturbations to avoid the potential bias :\nDeletion perturbation removes the selected words from the input sentence, and it can be regarded as a specific instantiation of sentence compression BIBREF21.\nMask perturbation replaces embedding vectors of the selected words with all-zero vectors BIBREF22, which is similar to Deletion perturbation except that it retains the placeholder.\nGrammatical Replacement perturbation replaces a word by another word of the same linguistic role (i.e., POS tags), yielding a sentence that is grammatically correct but semantically nonsensical BIBREF23, BIBREF24, such as “colorless green ideas sleep furiously”.\nFigure FIGREF19 illustrates the experimental results on Chinese$\\Rightarrow $English translation with Transformer. It shows that Attribution method consistently outperforms other methods against different perturbations on a various number of operations. Here the operation number denotes the number of perturbed words in a sentence. Specifically, we can make the following observations.\nUnder three different perturbations, perturbing words of top-most importance leads to lower BLEU scores than Random selected words. It confirms the existence of important words, which have greater impacts on translation performance. Furthermore, perturbing important words identified by Attribution outperforms the Random method by a large margin (more than 4.0 BLEU under 5 operations).\nFigure FIGREF19 shows that two black-box methods (i.e., Content, Frequency) perform only slightly better than the Random method. Specifically, the Frequency method demonstrates even worse performances under the Mask perturbation. Therefore, linguistic properties (such as POS tags) and the word frequency can only partially help identify the important words, but it is not as accurate as we thought. In the meanwhile, it is intriguing to explore what exact linguistic characteristics these important words reveal, which will be introduced in Section SECREF5.\nWe also evaluate the Attention method, which bases on the encoder-decoder attention scores at the last layer of Transformer. Note that the Attention method is also used to simulate the best black-box method SOCRAT, and the results show that it is more effective than black-box methods and the Random baseline. Given the powerful Attention method, Attribution method still achieves best performances under all three perturbations. Furthermore, we find that the gap between Attribution and Attention is notably large (around $1.0+$ BLEU difference). Attention method does not provide as accurate word importance as the Attribution, which exhibits the superiority of gradient-based methods and consists with the conclusion reported in the previous study BIBREF8.\nIn addition, as shown in Figure FIGREF19, the perturbation effectiveness of Deletion, Mask, and Grammatical Replacement varies from strong to weak. In the following experiments, we choose Mask as the representative perturbation operation for its moderate perturbation performance, based on which we compare two most effective methods Attribution and Attention.\nWe validate the effectiveness of the proposed approach using a different NMT architecture RNN-Search on the Chinese$\\Rightarrow $English translation task. The results are shown in Figure FIGREF20(a). We observe that the Attribution method still outperforms both Attention method and Random method by a decent margin. By comparing to Transformer, the results also reveal that the RNN-Search model is less robust to these perturbations. To be specific, under the setting of five operations and Attribution method, Transformer shows a relative decrease of $55\\%$ on BLEU scores while the decline of RNN-Search model is $64\\%$.\nWe further conduct experiments on another two language pairs (i.e., English$\\Rightarrow $French, English$\\Rightarrow $Japanese in Figures FIGREF20(b, c)) as well as the reverse directions (Figures FIGREF20(d, e, f)) using Transformer under the Mask perturbation. In all the cases, Attribution shows the best performance while Random achieves the worst result. More specifically, Attribution method shows similar translation quality degradation on all three language-pairs, which declines to around the half of the original BLEU score with five operations.\nThere exists another straightforward method, Erasure BIBREF7, BIBREF22, BIBREF25, which directly evaluates the word importance by measuring the translation performance degradation of each word. Specifically, it erases (i.e., Mask) one word from the input sentence each time and uses the BLEU score changes to denote the word importance (after normalization).\nIn Figure FIGREF31, we compare Erasure method with Attribution method under the Mask perturbation. The results show that Attribution method is less effective than Erasure method when only one word is perturbed. But it outperforms the Erasure method when perturbing 2 or more words. The results reveal that the importance calculated by erasing only one word cannot be generalized to multiple-words scenarios very well. Besides, the Erasure method is a supervised method which requires ground-truth references, and finding a better words combination is computation infeasible when erasing multiple words.\nWe close this section by pointing out that our gradient-based method consistently outperforms its black-box counterparts in various settings, demonstrating the effectiveness and universality of exploiting gradients for estimating word importance. In addition, our approach is on par with or even outperforms the supervised erasure method (on multiple-word perturbations). This is encouraging since our approach does not require any external resource and is fully unsupervised.\nTo make the conclusion convincing, we first choose two large-scale datasets that are publicly available, i.e., Chinese-English and EnglishFrench.",

        "answer": "Markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques.",
        "evidence": "Chatbots such as dialog and question-answering systems have a long history in AI and natural language processing. Early such systems were mostly built using markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Recent neural conversation models BIBREF4 , BIBREF5 , BIBREF6 are even able to perform open-ended conversations. However, since they do not use explicit knowledge bases and do not perform inference, they often suffer from generic and dull responses BIBREF5 , BIBREF7 . More recently, BIBREF8 and BIBREF9 proposed to use knowledge bases (KBs) to help generate responses for knowledge-grounded conversation. However, one major weakness of all existing chat systems is that they do not explicitly or implicitly learn new knowledge in the conversation process. This seriously limits the scope of their applications. In contrast, we humans constantly learn new knowledge in our conversations. Even if some existing systems can use very large knowledge bases either harvested from a large data source such as the Web or built manually, these KBs still miss a large number of facts (knowledge) BIBREF10 . It is thus important for a chatbot to continuously learn new knowledge in the conversation process to expand its KB and to improve its conversation ability.\nIn recent years, researchers have studied the problem of KB completion, i.e., inferring new facts (knowledge) automatically from existing facts in a KB. KB completion (KBC) is defined as a binary classification problem: Given a query triple, ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ), we want to predict whether the source entity INLINEFORM3 and target entity INLINEFORM4 can be linked by the relation INLINEFORM5 . However, existing approaches BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 solve this problem under the closed-world assumption, i.e., INLINEFORM6 , INLINEFORM7 and INLINEFORM8 are all known to exist in the KB. This is a major weakness because it means that no new knowledge or facts may contain unknown entities or relations. Due to this limitation, KBC is clearly not sufficient for knowledge learning in conversations because in a conversation, the user can say anything, which may contain entities and relations that are not already in the KB.\nIn this paper, we remove this assumption of KBC, and allow all INLINEFORM0 , INLINEFORM1 and INLINEFORM2 to be unknown. We call the new problem open-world knowledge base completion (OKBC). OKBC generalizes KBC. Below, we show that solving OKBC naturally provides the ground for knowledge learning and inference in conversations. In essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.\nFrom the perspective of knowledge learning in conversations, essentially we can extract two key types of information, true facts and queries, from the user utterances. Queries are facts whose truth values need to be determined. Note that we do not study fact or relation extraction in this paper as there is an extensive work on the topic. (1) For a true fact, we will incorporate it into the KB. Here we need to make sure that it is not already in the KB, which involves relation resolution and entity linking. After a fact is added to the KB, we may predict that some related facts involving some existing relations in the KB may also be true (not logical implications as they can be automatically inferred). For example, if the user says “Obama was born in USA,” the system may guess that (Obama, CitizenOf, USA) (meaning that Obama is a citizen of USA) could also be true based on the current KB. To verify this fact, it needs to solve a KBC problem by treating (Obama, CitizenOf, USA) as a query. This is a KBC problem because the fact (Obama, BornIn, USA) extracted from the original sentence has been added to the KB. Then Obama and USA are in the KB. If the KBC problem is solved, it learns a new fact (Obama, CitizenOf, USA) in addition to the extracted fact (Obama, BornIn, USA). (2) For a query fact, e.g., (Obama, BornIn, USA) extracted from the user question “Was Obama born in USA?” we need to solve the OKBC problem if any of “Obama, “BornIn”, or “USA\" is not already in the KB.\nWe can see that OKBC is the core of a knowledge learning engine for conversation. Thus, in this paper, we focus on solving it. We assume that other tasks such as fact/relation extraction and resolution and guessing of related facts of an extracted fact are solved by other sub-systems.\nWe solve the OKBC problem by mimicking how humans acquire knowledge and perform reasoning in an interactive conversation. Whenever we encounter an unknown concept or relation while answering a query, we perform inference using our existing knowledge. If our knowledge does not allow us to draw a conclusion, we typically ask questions to others to acquire related knowledge and use it in inference. The process typically involves an inference strategy (a sequence of actions), which interleaves a sequence of processing and interactive actions. A processing action can be the selection of related facts, deriving inference chain, etc., that advances the inference process. An interactive action can be deciding what to ask, formulating a suitable question, etc., that enable us to interact. The process helps grow the knowledge over time and the gained knowledge enables us to communicate better in the future. We call this lifelong interactive learning and inference (LiLi). Lifelong learning is reflected by the facts that the newly acquired facts are retained in the KB and used in inference for future queries, and that the accumulated knowledge in addition to the updated KB including past inference performances are leveraged to guide future interaction and learning. LiLi should have the following capabilities:\nThis setting is ideal for many NLP applications like dialog and question-answering systems that naturally provide the scope for human interaction and demand real-time inference.\nLiLi starts with the closed-world KBC approach path-ranking (PR) BIBREF11 , BIBREF17 and extends KBC in a major way to open-world knowledge base completion (OKBC). For a relation INLINEFORM0 , PR works by enumerating paths (except single-link path INLINEFORM1 ) between entity-pairs linked by INLINEFORM2 in the KB and use them as features to train a binary classifier to predict whether a query INLINEFORM3 should be in the KB. Here, a path between two entities is a sequence of relations linking them. In our work, we adopt the latest PR method, C-PR BIBREF16 and extend it to make it work in the open-world setting. C-PR enumerates paths by performing bidirectional random walks over the KB graph while leveraging the context of the source-target entity-pair. We also adopt and extend the compositional vector space model BIBREF20 , BIBREF21 with continual learning capability for prediction.\nGiven an OKBC query ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ) (e.g., “(Obama, CitizenOf, USA), which means whether Obama a citizen of USA), LiLi interacts with the user (if needed) by dynamically formulating questions (see the interaction example in Figure 1, which will be further explained in §3) and leverages the interactively acquired knowledge (supporting facts (SFs) in the figure) for continued inference. To do so, LiLi formulates a query-specific inference strategy and executes it. We design LiLi in a Reinforcement Learning (RL) setting that performs sub-tasks like formulating and executing strategy, training a prediction model for inference, and knowledge retention for future use. To the best of our knowledge, our work is the first to address the OKBC problem and to propose an interactive learning mechanism to solve it in a continuous or lifelong manner. We empirically verify the effectiveness of LiLi on two standard real-world KBs: Freebase and WordNet. Experimental results show that LiLi is highly effective in terms of its predictive performance and strategy formulation ability.\nChatbots such as dialog and question-answering systems have a long history in AI and natural language processing. Early such systems were mostly built using markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques (Banchs and Li, 2012; Ameixa et al. , 2014; Lowe et al. , 2015; Serban et al. , 2015).",

Tags such as “hate speech\" or metadata information imply a certain way of organizing the collection. Computational models provide another organization, which may differ in ways that provide more insight into how these categories manifest themselves, or fail to do so.\nMoreover, when using a supervised approach, the “errors”, i.e. disagreement between the system output and human-provided labels, can point towards interesting cases for closer analysis and help us reflect on our conceptualizations. In the words of BIBREF2 , they can be “opportunities for interpretation”. Other types of “failures” can be insightful as well. Sometimes there is a “dog that didn't bark” BIBREF49 –i.e., something that everyone thinks we should have found, but we did not. Or, sometimes the failures are telling us about the existence of something in the data that nobody noticed, or thought important, until then (e.g., the large number of travel journals in Darwin's reading lists).\nComputational text analysis is not a replacement for but rather an addition to the approaches one can take to analyze social and cultural phenomena using textual data. By moving back and forth between large-scale computational analyses and small-scale qualitative analyses, we can combine their strengths so that we can identify large-scale and long-term trends, but also tell individual stories. For example, the Reddit study on hate speech BIBREF0 raised various follow-up questions: Can we distinguish hate speech from people talking about hate speech? Did people find new ways to express hate speech? If so, did the total amount of online hate speech decrease after all? As possible next steps, a qualitative discourse analyst might examine a smaller corpus to investigate whether commenters were indeed expressing hate speech in new ways; a specialist in interview methodologies might reach out to commenters to better understand the role of online hate speech in their lives. Computational text analysis represents a step towards better understanding social and cultural phenomena, and it is in many cases better suited towards opening questions rather than closing them.\nComputational text analysis represents a step towards better understanding social and cultural phenomena, and it is in many cases better suited towards opening questions rather than closing them.",

We note that two of the systems are supervised and rely on the training set to build their classification models. Document frequency counts are also computed on the training set. Stemming is applied to allow more robust matching. The different keyphrase extraction models are briefly described below:\nEach model uses a distinct keyphrase candidate selection method that provides a trade-off between the highest attainable recall and the size of set of candidates. Table summarizes these numbers for each model. Syntax-based selection heuristics, as used by TopicRank and WINGNUS, are better suited to prune candidates that are unlikely to be keyphrases. As for KP-miner, removing infrequent candidates may seem rather blunt, but it turns out to be a simple yet effective pruning method when dealing with long documents. For details on how candidate selection methods affect keyphrase extraction, please refer to BIBREF16 .\nApart from TopicRank that groups similar candidates into topics, the other models do not have any redundancy control mechanism. Yet, recent work has shown that up to 12% of the overall error made by state-of-the-art keyphrase extraction systems were due to redundancy BIBREF6 , BIBREF17 .

In 1633, he joined the VOC and sailed to Batavia, now Jakarta, Indonesia. He participated in several voyages, including one to Japan. In 1642, Tasman was appointed by the VOC to lead an expedition to explore the uncharted regions of the Southern Pacific Ocean. His mission was to discover new trade routes and to establish trade relations with the native inhabitants. After leaving Batavia, Tasman sailed eastward and reached the coast of Tasmania, which he named Van Diemen's Land after his patron. He then sailed north and discovered the west coast of New Zealand, which he named Staten Landt, but later renamed Nieuw Zeeland after the Dutch province of Zeeland.\n\nDespite his achievements, Tasman's expedition was not entirely successful. The encounter with the Māori people on the South Island of New Zealand resulted in a violent confrontation, which left four of Tasman's men dead. He returned to Batavia without having made any significant contact with the native inhabitants or establishing any trade relations. Nonetheless, Tasman's expedition paved the way for further exploration and colonization of Australia and New Zealand by the Europeans. Tasman continued to serve the Dutch East India Company until his death in 1659, leaving behind a legacy as one of the greatest explorers of his time.\n\nOrigins and early life\n\nPortrait of Abel Tasman, his wife and daughter. Attributed to Jacob Gerritsz Cuyp, 1637 (not authenticated).\nAbel Tasman was born around 1603 in Lutjegast, a small village in the province of Groningen, in the north of the Netherlands. The oldest available source mentioning him is dated 27 December 1631 when, as a seafarer living in Amsterdam, the 28-year-old became engaged to marry 21-year-old Jannetje Tjaers, of Palmstraat in the Jordaan district of the city.\n\nRelocation to the Dutch East Indies\nEmployed by the Dutch East India Company (VOC), Tasman sailed from Texel (Netherlands) to Batavia, now Jakarta, in 1633 taking the southern Brouwer Route. While based in Batavia, Tasman took part in a voyage to Seram Island (in what is now the Maluku Province in Indonesia) because the locals had sold spices to other European nationalities than the Dutch. He had a narrow escape from death when in an incautious landing several of his companions were killed by the inhabitants of the island.\n\nBy August 1637, Tasman was back in Amsterdam, and the following year he signed on for another ten years and took his wife with him to Batavia. On 25 March 1638 he tried to sell his property in the Jordaan, but the purchase was cancelled.\n\nHe was second-in-command of a 1639 expedition of exploration into the north Pacific under Matthijs Quast. The fleet included the ships Engel and Gracht and reached Fort Zeelandia (Dutch Formosa) and Deshima (an artificial island off Nagasaki, Japan).\n\nFirst major voyage\nIn August 1642, the Council of the Indies, consisting of Antonie van Diemen, Cornelis van der Lijn, Joan Maetsuycker, Justus Schouten, Salomon Sweers, Cornelis Witsen, and Pieter Boreel in Batavia dispatched Tasman and Franchoijs Jacobszoon Visscher on a voyage of exploration to little-charted areas east of the Cape of Good Hope, west of Staten Land (near the Cape Horn of South America) and south of the Solomon Islands.\n\nOne of the objectives was to obtain knowledge of \"all the totally unknown\" Provinces of Beach. This was a purported yet non-existent landmass said to have plentiful gold, which had appeared on European maps since the 15th century, as a result of an error in some editions of Marco Polo's works.\n\nThe expedition was to use two small ships, Heemskerck and Zeehaen.\n\nMauritius\nIn accordance with Visscher's directions, Tasman sailed from Batavia on 14 August 1642 and arrived at Mauritius on 5 September 1642, according to the captain's journal. The reason for this was the crew could be fed well on the island; there was plenty of fresh water and timber to repair the ships. Tasman got the assistance of the governor Adriaan van der Stel.\n\nBecause of the prevailing winds, Mauritius was chosen as a turning point. After a four-week stay on the island, both ships left on 8 October using the Roaring Forties to sail east as fast as possible. (No one had gone as far as Pieter Nuyts in 1626/27.) On 7 November, snow and hail influenced the ship's council to alter course to a more north-easterly direction, with the intention of having the Solomon Islands as their destination.\n\nTasmania\n\nCoastal cliffs of Tasman Peninsula\nOn 24 November 1642, Tasman reached and sighted the west coast of Tasmania, north of Macquarie Harbour. He named his discovery Van Diemen's Land, after Antonio van Diemen, Governor-General of the Dutch East Indies.\n\nProceeding south, Tasman skirted the southern end of Tasmania and turned north-east. He then tried to work his two ships into Adventure Bay on the east coast of South Bruny Island, but he was blown out to sea by a storm. This area he named Storm Bay. Two days later, on 1 December, Tasman anchored to the north of Cape Frederick Hendrick just north of the Forestier Peninsula. On 2 December, two ship's boats under the command of the Pilot, Major Visscher, rowed through the Marion Narrows into Blackman Bay, and then west to the outflow of Boomer Creek where they gathered some edible \"greens\". Tasman named the bay, Frederick Hendrik Bay, which included the present North Bay, Marion Bay and what is now Blackman Bay. (Tasman's original naming, Frederick Henrick Bay, was mistakenly transferred to its present location by Marion Dufresne in 1772). The next day, an attempt was made to land in North Bay. However, because the sea was too rough, a ship's carpenter swam through the surf and planted the Dutch flag. Tasman then claimed formal possession of the land on 3 December 1642.\n\nFor two more days, he continued to follow the east coast northward to see how far it went. When the land veered to the north-west at Eddystone Point, he tried to follow the coast line but his ships were suddenly hit by the Roaring Forties howling through Bass Strait. Tasman was on a mission to find the Southern Continent not more islands, so he abruptly turned away to the east and continued his continent-hunting.\n\nNew Zealand\n\nMurderers' Bay, drawing by Isaack Gilsemans\n\nMāori haka\nTasman had intended to proceed in a northerly direction but as the wind was unfavourable he steered east. The expedition endured a rough voyage and in one of his diary entries Tasman claimed that his compass was the only thing that had kept him alive.\n\nOn 13 December 1642 they sighted land on the north-west coast of the South Island of New Zealand, becoming the first Europeans to sight New Zealand. Tasman named it Staten Landt \"in honour of the States General\" (Dutch parliament). He wrote, \"it is possible that this land joins to the Staten Landt but it is uncertain\", referring to Isla de los Estados, a landmass of the same name at the southern tip of South America, encountered by the Dutch navigator Jacob Le Maire in 1616. However, in 1643 Brouwer's expedition to Valdivia found out that Staaten Landt was separated by sea from the hypothetical Southern Land. Tasman continued: \"We believe that this is the mainland coast of the unknown Southland.\" Tasman thought he had found the western side of the long-imagined Terra Australis that stretched across the Pacific to near the southern tip of South America.\n\nAfter sailing north then east for five days, the expedition anchored about 7 kilometres (4.3 mi) from the coast off what is now Golden Bay. A group of Māori paddled out in a waka (canoe) and attacked some sailors who were rowing between the two Dutch vessels. Four sailors were clubbed to death with patu.\nIn the evening about one hour after sunset we saw many lights on land and four vessels near the shore, two of which betook themselves towards us. When our two boats returned to the ships reporting that they had found not less than thirteen fathoms of water, and with the sinking of the sun (which sank behind the high land) they had been still about half a mile from the shore. After our people had been on board about one glass, people in the two canoes began to call out to us in gruff, hollow voices. We could not in the least understand any of it; however, when they called out again several times we called back to them as a token answer. But they did not come nearer than a stone's shot. They also blew many times on an instrument, which produced a sound like the moors' trumpets. We had one of our sailors (who could play somewhat on the trumpet) play some tunes to them in answer.\"\n\nAs Tasman sailed out of the bay he observed 22 waka near the shore, of which \"eleven swarming with people came off towards us.\" The waka approached the Zeehaen which fired and hit a man in the largest waka holding a small white flag. Canister shot also hit the side of a waka. It has been speculated that the local Maori had thought the Dutch were trying to land at a major agricultural area, which the Māori were trying to protect. Tasman named the area \"Murderers' Bay\".\n\nThe expedition then sailed north, sighting Cook Strait, which it mistook for a bight and named \"Zeehaen's Bight\". Two names that the expedition gave to landmarks in the far north of New Zealand still endure: Cape Maria van Diemen and Three Kings Islands. (Kaap Pieter Boreels was renamed Cape Egmont by Captain James Cook 125 years later.)\n\nReturn voyage\n\nTongatapu, the main island of Tonga; drawing by Isaack Gilsemans\n\nThe bay of Tongatapu with the two ships; drawing by Isaack Gilsemans\nEn route back to Batavia, Tasman came across the Tongan archipelago on 20 January 1643. While passing the Fiji Islands Tasman's ships came close to being wrecked on the dangerous reefs of the north-eastern part of the Fiji group. He charted the eastern tip of Vanua Levu and Cikobia-i-Lau before making his way back into the open sea.\n\nThe expedition turned north-west towards New Guinea and arrived back in Batavia on 15 June 1643.\n\nSecond major voyage\nTasman left Batavia on 30 January 1644 on his second voyage with three ships (Limmen, Zeemeeuw and the tender Braek). He followed the south coast of New Guinea eastwards in an attempt to find a passage to the eastern side of New Holland. However, he missed the Torres Strait between New Guinea and Australia, probably due to the numerous reefs and islands obscuring potential routes, and continued his voyage by following the shore of the Gulf of Carpentaria westwards along the north Australian coast. He mapped the north coast of Australia, making observations on New Holland and its people. He arrived back in Batavia in August 1644.\n\nFrom the point of view of the Dutch East India Company, Tasman's explorations were a disappointment: he had neither found a promising area for trade nor a useful new shipping route. Although Tasman was received courteously on his return, the company was upset that Tasman had not fully explored the lands he found, and decided that a more \"persistent explorer\" should be chosen for any future expeditions. For over a century, until the era of James Cook, Tasmania and New Zealand were not visited by Europeans; mainland Australia was visited, but usually only by accident.\n\nLater life\nOn 2 November 1644, Abel Tasman was appointed a member of the Council of Justice in Batavia. He went to Sumatra in 1646, and in August 1647 to Siam (now Thailand) with letters from the company to the King. In May 1648, he was in charge of an expedition sent to Manila to try to intercept and loot the Spanish silver ships coming from America, but he had no success and returned to Batavia in January 1649. In November 1649, he was charged and found guilty of having in the previous year hanged one of his men without trial, was suspended from his office of commander, fined, and made to pay compensation to the relatives of the sailor. On 5 January 1651, he was formally reinstated in his rank and spent his remaining years at Batavia. He was in good circumstances, being one of the larger landowners in the town. He died at Batavia on 10 October 1659 and was survived by his second wife and a daughter by his first wife. His property was divided between his wife and his daughter. In his will (dating from 1657), he left 25 guilders to the poor of his village, Lutjegast.\n\nAlthough Tasman's pilot, Frans Visscher, published Memoir concerning the discovery of the South land in 1642, Tasman's detailed journal was not published until 1898. Nevertheless, some of his charts and maps were in general circulation and used by subsequent explorers. The journal signed by Abel Tasman of the 1642 voyage is held in the Dutch National Archives at The Hague.\n\nLegacy\nTasman's ten-month voyage in 1642–43 had significant consequences. By circumnavigating Australia (albeit at a distance) Tasman proved that the small fifth continent was not joined to any larger sixth continent, such as the long-imagined Southern Continent. Further, Tasman's suggestion that New Zealand was the western side of that Southern Continent was seized upon by many European cartographers who, for the next century, depicted New Zealand as the west coast of a Terra Australis rising gradually from the waters around Tierra del Fuego. This theory was eventually disproved when Captain Cook circumnavigated New Zealand in 1769.\n\nMultiple places have been named after Tasman, including:\n\nthe Australian island and state of Tasmania, renamed after him, formerly Van Diemen's land. It includes features such as:\nthe Tasman Peninsula.\nthe Tasman Bridge.\nthe Tasman Highway.\nthe Tasman Sea.\n\nin New Zealand:\nthe Tasman Glacier.\nTasman Lake.\nthe Tasman River.\nMount Tasman.\nthe Abel Tasman National Park.\nTasman Bay / Te Tai-o-Aorere.\nthe Tasman District.\nAbel Tasman Monument.",

He was appointed by the VOC to explore the uncharted regions of the Southern Pacific Ocean and discovered Van Diemen's Land, Staten Landt, and Nieuw Zeeland. Despite his achievements, his expedition was not entirely successful due to a violent confrontation with the Māori people on the South Island of New Zealand. Nonetheless, his expedition paved the way for further exploration and colonization of Australia and New Zealand by the Europeans. Abel Tasman was born around 1603 in Lutjegast, a small village in the province of Groningen, in the north of the Netherlands.\n\nHe served the Dutch East India Company until his death in 1659, leaving behind a legacy as one of the greatest explorers of his time. He was engaged to marry 21-year-old Jannetje Tjaers, of Palmstraat in the Jordaan district of the city, and took part in a voyage to Seram Island. He was second-in-command of a 1639 expedition of exploration into the north Pacific under Matthijs Quast, which reached Fort Zeelandia and Deshima.\n\nThe Council of the Indies dispatched Tasman and Franchoijs Jacobszoon Visscher on a voyage to explore the Provinces of Beach, which had appeared on European maps since the 15th century.

        "answer": "With the advent of next-generation sequencing we are obtaining enough sequence data to map the genes of complex diseases including infertility, breast cancer or Alzheimer's disease. Genome-wide association studies are a useful approach to pinpoint the mutations responsible for such complex diseases. Through these studies, thousands of DNA variants have been identified that are associated with similar diseases and traits. Furthermore, the possibility for genes to be used at prognosis, diagnosis or treatment is one of the most essential applications. Many studies are discussing both the promising ways to choose the genes to be used and the problems and pitfalls of using genes to predict disease presence or prognosis.\n\nGenome-wide association studies have successfully identified thousands of common genetic variants for complex diseases and traits; however, these common variants only explain a small fraction of heritability. Rare variants may account for some of the missing heritability. Large-scale whole genome sequencing studies have rapidly sequenced millions of whole genomes, and such studies have identified hundreds of millions of rare variants. Functional annotations predict the effect or function of a genetic variant and help to prioritize rare functional variants, and incorporating these annotations can effectively boost the power of genetic association of rare variants analysis of whole genome sequencing studies. Some tools have been developed to provide all-in-one rare variant association analysis for whole-genome sequencing data, including integration of genotype data and their functional annotations, association analysis, result summary and visualization. Meta-analysis of whole genome sequencing studies provides an attractive solution to the problem of collecting large sample sizes for discovering rare variants associated with complex phenotypes.",

        "question": "What is the novel concept of word subspace in this paper?",
        "answer": "It is mathematically defined as a low dimensional linear subspace in a word vector space with high dimensionality.",
        "evidence": "Text classification has become an indispensable task due to the rapid growth in the number of texts in digital form available online. It aims to classify different texts, also called documents, into a fixed number of predefined categories, helping to organize data, and making easier for users to find the desired information. Over the past three decades, many methods based on machine learning and statistical models have been applied to perform this task, such as latent semantic analysis (LSA), support vector machines (SVM), and multinomial naive Bayes (MNB).\nThe first step in utilizing such methods to categorize textual data is to convert the texts into a vector representation. One of the most popular text representation models is the bag-of-words model BIBREF0 , which represents each document in a collection as a vector in a vector space. Each dimension of the vectors represents a term (e.g., a word, a sequence of words), and its value encodes a weight, which can be how many times the term occurs in the document.\nDespite showing positive results in tasks such as language modeling and classification BIBREF1 , BIBREF2 , BIBREF3 , the BOW representation has limitations: first, feature vectors are commonly very high-dimensional, resulting in sparse document representations, which are hard to model due to space and time complexity. Second, BOW does not consider the proximity of words and their position in the text and consequently cannot encode the words semantic meanings.\nTo solve these problems, neural networks have been employed to learn vector representations of words BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . In particular, the word2vec representation BIBREF8 has gained attention. Given a training corpus, word2vec can generate a vector for each word in the corpus that encodes its semantic information. These word vectors are distributed in such a way that words from similar contexts are represented by word vectors with high correlation, while words from different contexts are represented by word vectors with low correlation.\nOne crucial aspect of the word2vec representation is that arithmetic and distance calculation between two word vectors can be performed, giving information about their semantic relationship. However, rather than looking at pairs of word vectors, we are interested in studying the relationship between sets of vectors as a whole and, therefore, it is desirable to have a text representation based on a set of these word vectors.\nTo tackle this problem, we introduce the novel concept of word subspace. It is mathematically defined as a low dimensional linear subspace in a word vector space with high dimensionality. Given that words from texts of the same class belong to the same context, it is possible to model word vectors of each class as word subspaces and efficiently compare them in terms of similarity by using canonical angles between the word subspaces. Through this representation, most of the variability of the class is retained. Consequently, a word subspace can effectively and compactly represent the context of the corresponding text. We achieve this framework through the mutual subspace method (MSM) BIBREF9 .\nThe word subspace of each text class is modeled by applying PCA without data centering to the set of word vectors of the class. When modeling the word subspaces, we assume only one occurrence of each word inside the class.\nHowever, as seen in the BOW approach, the frequency of words inside a text is an informative feature that should be considered. In order to introduce this feature in the word subspace modeling and enhance its performance, we further extend the concept of word subspace to the term-frequency (TF) weighted word subspace.\nIn this extension, we consider a set of weights, which encodes the words frequencies, when performing the PCA. Text classification with TF weighted word subspace can also be performed under the framework of MSM. We show the validity of our modeling through experiments on the Reuters database, an established database for natural language processing tasks. We demonstrate the effectiveness of the word subspace formulation and its extension, comparing our methods' performance to various state-of-art methods.\nThe main contributions of our work are:\nThe remainder of this paper is organized as follows. In Section \"Related Work\" , we describe the main works related to text classification. In Section \"Word subspace\" , we present the formulation of our proposed word subspace. In Section \"Conventional text classification methods\" , we explain how text classification with word subspaces is performed under the MSM framework. Then, we present the TF weighted word subspace extension in Section \"TF weighted word subspace\" . Evaluation experiments and their results are described in Section \"Experimental Evaluation\" . Further discussion is then presented in Section \"Discussion\" , and our conclusions are described in Section \"Conclusions and Future Work\" .\nIt is mathematically defined as a low dimensional linear subspace in a word vector space with high dimensionality.",

        "evidence": "The proliferation of the online social media has lately resulted in the democratization of online content sharing. Among other media, Twitter is very popular for research and application purposes due to its scale, representativeness and ease of public access to its content. However, tweets, that are short messages of up to 140 characters, pose several challenges to traditional Natural Language Processing (NLP) systems due to the creative use of characters and punctuation symbols, abbreviations ans slung language.\nNamed Entity Recognition (NER) is a fundamental step for most of the information extraction pipelines. Importantly, the terse and difficult text style of tweets presents serious challenges to NER systems, which are usually trained using more formal text sources such as newswire articles or Wikipedia entries that follow particular morpho-syntactic rules. As a result, off-the-self tools trained on such data perform poorly BIBREF0 . The problem becomes more intense as the number of entities to be identified increases, moving from the traditional setting of very few entities (persons, organization, time, location) to problems with more. Furthermore, most of the resources (e.g., software tools) and benchmarks for NER are for text written in English. As the multilingual content online increases, and English may not be anymore the lingua franca of the Web. Therefore, having resources and benchmarks in other languages is crucial for enabling information access worldwide.\nIn this paper, we propose a new benchmark for the problem of NER for tweets written in French. The tweets were collected using the publicly available Twitter API and annotated with 13 types of entities. The annotators were native speakers of French and had previous experience in the task of NER. Overall, the generated datasets consists of INLINEFORM0 tweets, split in training and test parts.\nThe paper is organized in two parts. In the first, we discuss the data preparation steps (collection, annotation) and we describe the proposed dataset. The dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated. Following, the second part of the paper presents an overview of baseline systems and the approaches employed by the systems that participated. We conclude with a discussion of the performance of Twitter NER systems and remarks for future work.\nThe tweets were collected using the publicly available Twitter API and annotated with 13 types of entities.",

Bayly was suspected of killing her, but he was never charged.\n\nBill Bayly and his wife Phyllis had been dairy farming at Ruawaro, near Huntly, since November 1928. Their neighbours were Samuel and Christobel Lakey. Relations between Bill Bayly and the Lakeys were initially friendly, but soured when Mrs Lakey was said to have accused Bayly of having murdered his niece.\n\nOn 16 October 1933 neighbours were concerned as to why the Lakey's cows hadn't been milked that morning. Christobel was discovered lying face down in her pond next to the farmhouse. She had been struck a blow to the face then held down underwater until she drowned. Her husband was missing. Some speculated that her husband had killed her and fled, but it soon became evident that both Lakeys had been the victims of foul play. Two days later bloodstains were found on a wheeled frame near the boundary between the Lakey and Bayly farms, bloodstains were discovered on Bill's sledge, Lakey's guns were found buried in Bayly's swamp, and chemical tests revealed charred bone fragments on a shovel taken from his dairy.\n\nIn December Bayly, who had been under surveillance by the police, disappeared, leaving a suicide note. He soon surfaced in Auckland, and was arrested for the murder of Christobel Lakey. More evidence was found in Bayly's garden. Bayly had attempted to incinerate all traces of Lakey.

        "question": "Does the FS0 mean Baseline lexical features in the experiment?",
        "answer": "Yes, it is.",
        "evidence": "In the following experiment, we focus on automatic identification of arguments in the discourse. Our approach is based on supervised and semi-supervised machine learning methods on the gold data Toulmin dataset introduced in section SECREF51 .\nAn argument consists of different components (such as premises, backing, etc.) which are implicitly linked to the claim. In principle one document can contain multiple independent arguments. However, only 4% of the documents in our dataset contain arguments for both sides of the issue. Thus we simplify the task and assume there is only one argument per document.\nGiven the low inter-annotator agreement on the pathos dimension (Table TABREF77 ), we focus solely on recognizing the logical dimension of argument. The pathos dimension of argument remains an open problem for a proper modeling as well as its later recognition.\nSince the smallest annotation unit is a token and the argument components do not overlap, we approach identification of argument components as a sequence labeling problem. We use the BIO encoding, so each token belongs to one of the following 11 classes: O (not a part of any argument component), Backing-B, Backing-I, Claim-B, Claim-I, Premise-B, Premise-I, Rebuttal-B, Rebuttal-I, Refutation-B, Refutation-I. This is the minimal encoding that is able to distinguish two adjacent argument components of the same type. In our data, 48% of all adjacent argument components of the same type are direct neighbors (there are no \"O\" tokens in between).\nWe report Macro- INLINEFORM0 score and INLINEFORM1 scores for each of the 11 classes as the main evaluation metric. This evaluation is performed on the token level, and for each token the predicted label must exactly match the gold data label (classification of tokens into 11 classes).\nAs instances for the sequence labeling model, we chose sentences rather than tokens. During our initial experiments, we observed that building a sequence labeling model for recognizing argument components as sequences of tokens is too fine-grained, as a single token does not convey enough information that could be encoded as features for a machine learner. However, as discussed in section UID73 , the annotations were performed on data pre-segmented to sentences and annotating tokens was necessary only when the sentence segmentation was wrong or one sentence contained multiple argument components. Our corpus consists of 3899 sentences, from which 2214 sentences (57%) contain no argument component. From the remaining ones, only 50 sentences (1%) have more than one argument component. Although in 19 cases (0.5%) the sentence contains a Claim-Premise pair which is an important distinction from the argumentation perspective, given the overall small number of such occurrences, we simplify the task by treating each sentence as if it has either one argument component or none.\nThe approximation with sentence-level units is explained in the example in Figure FIGREF112 . In order to evaluate the expected performance loss using this approximation, we used an oracle that always predicts the correct label for the unit (sentence) and evaluated it against the true labels (recall that the evaluation against the true gold labels is done always on token level). We lose only about 10% of macro INLINEFORM0 score (0.906) and only about 2% of accuracy (0.984). This performance is still acceptable, while allowing to model sequences where the minimal unit is a sentence.\nTable TABREF114 shows the distribution of the classes in the gold data Toulmin, where the labeling was already mapped to the sentences. The little presence of rebuttal and refutation (4 classes account only for 3.4% of the data) makes this dataset very unbalanced.\nWe chose SVMhmm BIBREF111 implementation of Structural Support Vector Machines for sequence labeling. Each sentence ( INLINEFORM0 ) is represented as a vector of real-valued features.\nWe defined the following feature sets:\nFS0: Baseline lexical features\nword uni-, bi-, and tri-grams (binary)\nFS1: Structural, morphological, and syntactic features\nFirst and last 3 tokens. Motivation: these tokens may contain discourse markers or other indicators for argument components, such as “therefore” and “since” for premises or “think” and “believe” for claims.\nRelative position in paragraph and relative position in document. Motivation: We expect that claims are more likely to appear at the beginning or at the end of the document.\nNumber of POS 1-3 grams, dependency tree depth, constituency tree production rules, and number of sub-clauses. Based on BIBREF113 .\nFS2: Topic and sentiment features\n30 features taken from a vector representation of the sentence obtained by using Gibbs sampling on LDA model BIBREF114 , BIBREF115 with 30 topics trained on unlabeled data from the raw corpus. Motivation: Topic representation of a sentence might be valuable for detecting off-topic sentences, namely non-argument components.\nScores for five sentiment categories (from very negative to very positive) obtained from Stanford sentiment analyzer BIBREF116 . Motivation: Claims usually express opinions and carry sentiment.\nFS3: Semantic, coreference, and discourse features\nBinary features from Clear NLP Semantic Role Labeler BIBREF117 . Namely, we extract agent, predicate + agent, predicate + agent + patient + (optional) negation, argument type + argument value, and discourse marker which are based on PropBank semantic role labels. Motivation: Exploit the semantics of Capturing the semantics of the sentences.\nBinary features from Stanford Coreference Chain Resolver BIBREF118 , e.g., presence of the sentence in a chain, transition type (i.e., nominal–pronominal), distance to previous/next sentences in the chain, or number of inter-sentence coreference links. Motivation: Presence of coreference chains indicates links outside the sentence and thus may be informative, for example, for classifying whether the sentence is a part of a larger argument component.\nResults of a PTDB-style discourse parser BIBREF119 , namely the type of discourse relation (explicit, implicit), presence of discourse connectives, and attributions. Motivation: It has been claimed that discourse relations play a role in argumentation mining BIBREF120 .\nFS4: Embedding features\n300 features from word embedding vectors using word embeddings trained on part of the Google News dataset BIBREF121 . In particular, we sum up embedding vectors (dimensionality 300) of each word, resulting into a single vector for the entire sentence. This vector is then directly used as a feature vector. Motivation: Embeddings helped to achieve state-of-the-art results in various NLP tasks BIBREF116 , BIBREF122 .\nExcept the baseline lexical features, all feature types are extracted not only for the current sentence INLINEFORM0 , but also for INLINEFORM1 preceding and subsequent sentences, namely INLINEFORM2 , INLINEFORM3 , INLINEFORM4 INLINEFORM5 , INLINEFORM6 , where INLINEFORM7 was empirically set to 4. Each feature is then represented with a prefix to determine its relative position to the current sequence unit.\nLet us first discuss the upper bounds of the system. Performance of the three human annotators is shown in the first column of Table TABREF139 (results are obtained from a cumulative confusion matrix). The overall Macro- INLINEFORM0 score is 0.602 (accuracy 0.754). If we look closer at the different argument components, we observe that humans are good at predicting claims, premises, backing and non-argumentative text (about 0.60-0.80 INLINEFORM1 ), but on rebuttal and refutation they achieve rather low scores. Without these two components, the overall human Macro- INLINEFORM2 would be 0.707. This trend follows the inter-annotator agreement scores, as discussed in section UID75 .\nIn our experiments, the feature sets were combined in the bottom-up manner, starting with the simple lexical features (FS0), adding structural and syntactic features (FS1), then adding topic and sentiment features (FS2), then features reflecting the discourse structure (FS3), and finally enriched with completely unsupervised latent vector space representation (FS4). In addition, we were gradually removing the simple features (e.g., without lexical features, without syntactic features, etc.) to test the system with more “abstract” feature sets (feature ablation). The results are shown in Table TABREF139 .\nThe overall best performance (Macro- INLINEFORM0 0.251) was achieved using the rich feature sets (01234 and 234) and significantly outperformed the baseline as well as other feature sets. Classification of non-argumentative text (the \"O\" class) yields about 0.7 INLINEFORM1 score even in the baseline setting. The boundaries of claims (Cla-B), premises (Pre-B), and backing (Bac-B) reach in average lower scores then their respective inside tags (Cla-I, Pre-I, Bac-I). It can be interpreted such that the system is able to classify that a certain sentence belongs to a certain argument component, but the distinction whether it is a beginning of the argument component is harder. The very low numbers for rebuttal and refutation have two reasons. First, these two argument components caused many disagreements in the annotations, as discussed in section UID86 , and were hard to recognize for the humans too. Second, these four classes have very few instances in the corpus (about 3.4%, see Table TABREF114 ), so the classifier suffers from the lack of training data.\nThe results for the in-domain cross validation scenario are shown in Table TABREF140 . Similarly to the cross-validation scenario, the overall best results were achieved using the largest feature set (01234). For mainstreaming and red-shirting, the best results were achieved using only the feature set 4 (embeddings). These two domains contain also fewer documents, compared to other domains (refer to Table TABREF71 ). We suspect that embeddings-based features convey important information when not enough in-domain data are available. This observation will become apparent in the next experiment.\nThe cross-domain experiments yield rather poor results for most of the feature combinations (Table TABREF141 ). However, using only feature set 4 (embeddings), the system performance increases rapidly, so it is even comparable to numbers achieved in the in-domain scenario. These results indicate that embedding features generalize well across domains in our task of argument component identification. We leave investigating better performing vector representations, such as paragraph vectors BIBREF123 , for future work.\nError analysis based on the probabilistic confusion matrix BIBREF124 shown in Table TABREF142 reveals further details. About a half of the instances for each class are misclassified as non-argumentative (the \"O\" prediction).\nBacking-B is often confused with Premise-B (12%) and Backing-I with Premise-I (23%). Similarly, Premise-I is misclassified as Backing-I in 9%. This shows that distinguishing between backing and premises is not easy because these two components are similar such that they support the claim, as discussed in section UID86 . We can also see that the misclassification is consistent among *-B and *-I tags.\nRebuttal is often misclassified as Premise (28% for Rebuttal-I and 18% for Rebuttal-B; notice again the consistency in *-B and *-I tags). This is rather surprising, as one would expect that rebuttal would be confused with a claim, because its role is to provide an opposing view.\nRefutation-B and Refutation-I is misclassified as Premise-I in 19% and 27%, respectively. This finding confirms the discussion in section UID86 , because the role of refutation is highly context-dependent. In a pragmatic perspective, it is put forward to indirectly support the claim by attacking the rebuttal, thus having a similar function to the premise.\nWe manually examined miss-classified examples produced the best-performing system to find out which phenomena pose biggest challenges. Properly detecting boundaries of argument components caused problems, as shown in Figure FIGREF146 (a). This goes in line with the granularity annotation difficulties discussed in section UID86 . The next example in Figure FIGREF146 (b) shows that even if boundaries of components were detected precisely, the distinction between premise and backing fails. The example also shows that in some cases, labeling on clause level is required (left-hand side claim and premise) but the approximation in the system cannot cope with this level of detail (as explained in section UID111 ). Confusing non-argumentative text and argument components by the system is sometimes plausible, as is the case of the last rhetorical question in Figure FIGREF146 (c). On the other hand, the last example in Figure FIGREF146 (d) shows that some claims using figurative language were hard to be identified. The complete predictions along with the gold data are publicly available.\nSVMhmm offers many hyper-parameters with suggested default values, from which three are of importance. Parameter INLINEFORM0 sets the order of dependencies of transitions in HMM, parameter INLINEFORM1 sets the order of dependencies of emissions in HMM, and parameter INLINEFORM2 represents a trading-off slack versus magnitude of the weight-vector. For all experiments, we set all the hyper-parameters to their default values ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ). Using the best performing feature set from Table TABREF139 , we experimented with a grid search over different values ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) but the results did not outperform the system trained with default parameter values.\nThe INLINEFORM0 scores might seem very low at the first glance. One obvious reason is the actual performance of the system, which gives a plenty of room for improvement in the future. But the main cause of low INLINEFORM2 numbers is the evaluation measure — using 11 classes on the token level is very strict, as it penalizes a mismatch in argument component boundaries the same way as a wrongly predicted argument component type. Therefore we also report two another evaluation metrics that help to put our results into a context.\nKrippendorff's INLINEFORM0 — It was also used for evaluating inter-annotator agreement (see section UID75 ).\nBoundary similarity BIBREF125 — Using this metric, the problem is treated solely as a segmentation task without recognizing the argument component types.\nAs shown in Table TABREF157 (the Macro- INLINEFORM0 scores are repeated from Table TABREF139 ), the best-performing system achieves 0.30 score using Krippendorf's INLINEFORM1 , which is in the middle between the baseline and the human performance (0.48) but is considered as poor from the inter-annotator agreement point of view BIBREF54 . The boundary similarity metrics is not directly suitable for evaluating argument component classification, but reveals a sub-task of finding the component boundaries. The best system achieved 0.32 on this measure. Vovk2013MT used this measure to annotate argument spans and his annotators achieved 0.36 boundary similarity score. Human annotators in BIBREF125 reached 0.53 boundary similarity score.\nThe overall performance of the system is also affected by the accuracy of individual NPL tools used for extracting features. One particular problem is that the preprocessing models we rely on (POS, syntax, semantic roles, coreference, discourse; see section UID115 ) were trained on newswire corpora, so one has to expect performance drop when applied on user-generated content. This is however a well-known issue in NLP BIBREF126 , BIBREF127 , BIBREF128 .\nTo get an impression of the actual performance of the system on the data, we also provide the complete output of our best performing system in one PDF document together with the gold annotations in the logos dimension side by side in the accompanying software package. We believe this will help the community to see the strengths of our model as well as possible limitations of our current approaches.\nWe defined the following feature sets: r FS0: Baseline lexical features – word uni-, bi-, and tri-grams (binary)",

        "evidence": "Kafka stores key-value messages that come from arbitrarily many processes called producers. The data can be partitioned into different \"partitions\" within different \"topics\". Within a partition, messages are strictly ordered by their offsets (the position of a message within a partition), and indexed and stored together with a timestamp. Other processes called \"consumers\" can read messages from partitions. For stream processing, Kafka offers the Streams API that allows writing Java applications that consume data from Kafka and write results back to Kafka. Apache Kafka also works with external stream processing systems such as Apache Apex, Apache Beam, Apache Flink, Apache Spark, Apache Storm, and Apache NiFi.\n\nKafka runs on a cluster of one or more servers (called brokers), and the partitions of all topics are distributed across the cluster nodes. Additionally, partitions are replicated to multiple brokers. This architecture allows Kafka to deliver massive streams of messages in a fault-tolerant fashion and has allowed it to replace some of the conventional messaging systems like Java Message Service (JMS), Advanced Message Queuing Protocol (AMQP), etc. Since the 0.11.0.0 release, Kafka offers transactional writes, which provide exactly-once stream processing using the Streams API.\n\nKafka supports two types of topics: Regular and compacted. Regular topics can be configured with a retention time or a space bound. If there are records that are older than the specified retention time or if the space bound is exceeded for a partition, Kafka is allowed to delete old data to free storage space. By default, topics are configured with a retention time of 7 days, but it's also possible to store data indefinitely. For compacted topics, records don't expire based on time or space bounds. Instead, Kafka treats later messages as updates to older message with the same key and guarantees never to delete the latest message per key. Users can delete messages entirely by writing a so-called tombstone message with null-value for a specific key.\n\nThere are five major APIs in Kafka:\n\nProducer API – Permits an application to publish streams of records.\nConsumer API – Permits an application to subscribe to topics and processes streams of records.\nConnector API – Executes the reusable producer and consumer APIs that can link the topics to the existing applications.\nStreams API – This API converts the input streams to output and produces the result.\nAdmin API – Used to manage Kafka topics, brokers, and other Kafka objects.\nThe consumer and producer APIs are decoupled from the core functionality of Kafka through an underlying messaging protocol.

        "answer": "By using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.",
        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nDue to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary.

        "question": "What does the insertion-deletion framework consist of?",
        "answer": "An insertion phase and a deletion phase that are executed iteratively",
        "evidence": "Neural sequence models BIBREF0, BIBREF1 typically generate outputs in an autoregressive left-to-right manner. These models have been successfully applied to a range of task, for example machine translation BIBREF2. They often rely on an encoder that processes the source sequence, and a decoder that generates the output sequence conditioned on the output of the encoder. The decoder will typically generate the target sequence one token at a time, in an autoregressive left-to-right fashion.\nRecently, research in insertion-based non- or partially- autoregressive models has spiked BIBREF3, BIBREF4, BIBREF5, BIBREF6. These model are more flexible than their autoregressive counterparts. They can generate sequences in any order, and can benefit from parallel token generation. They can learn complex orderings (e.g., tree orderings) and may be more applicable to task like cloze question answering BIBREF6 and text simplification, where the order of generation is not naturally left to right, and the source sequence might not be fully observed. One recently proposed approach is the Insertion Transformer BIBREF3, where the target sequence is modelled with insertion-edits. As opposed to traditional sequence-to-sequence models, the Insertion Transformer can generate sequences in any arbitrary order, where left-to-right is a special case. Additionally, during inference, the model is endowed with parallel token generation capabilities. The Insertion Transformer can be trained to follow a soft balanced binary tree order, thus allowing the model to generate $n$ tokens in $O(\\log _2 n)$ iterations.\nIn this work we propose to generalize this insertion-based framework, we present a framework which emits both insertions and deletions. Our Insertion-Deletion Transformer consists of an insertion phase and a deletion phase that are executed iteratively. The insertion phase follows the typical insertion-based framework BIBREF3. However, in the deletion phase, we teach the model to do deletions with on-policy training. We sample an input sequence on-policy from the insertion model (with on-policy insertion errors), and teach the deletion model its appropriate deletions.\nThis insertion-deletion framework allows for flexible sequence generation, parallel token generation and text editing. In a conventional insertion-based model, if the model makes a mistake during generation, this cannot be undone. Introducing the deletion phase makes it possible to undo the mistakes made by the insertion model, since it is trained on the on-policy errors of the insertion phase. The deletion model extension also enables the framework to efficiently handle tasks like text simplification and style transfer by starting the decoding process from the original source sequence.\nA concurrent work was recently proposed, called the Levenshtein Transformer (LevT) BIBREF7. The LevT framework also generates sequences with insertion and deletion operations. Our approach has some important distinctions and can be seen as a simplified version, for both the architecture and the training algorithm. The training algorithm used in the LevT framework uses an expert policy. This expert policy requires dynamic programming to minimize Levenshtein distance between the current input and the target. This approach was also explored by BIBREF8, BIBREF9. Their learning algorithm arguably adds more complexity than needed over the simple on-policy method we propose. The LevT framework consists of three stages, first the number of tokens to be inserted is predicted, then the actual tokens are predicted, and finally the deletion actions are emitted. The extra classifier to predict the number of tokens needed to be inserted adds an additional Transformer pass to each generation step. In practice, it is also unclear whether the LevT exhibits speedups over an insertion-based model following a balanced binary tree order. In contrast, our Insertion-Deletion framework only has one insertion phase and one deletion phase, without the need to predict the number of tokens needed to be inserted. This greatly simplifies the model architecture, training procedure and inference runtime.\nAn alternative approach for text editing is proposed by BIBREF10, which they dub Deliberation Networks. This work also acknowledges the potential benefits from post-editing output sequences and proposes a two-phase decoding framework to facilitate this.\nIn this paper, we present the insertion-deletion framework as a proof of concept by applying it to two synthetic character-based translation tasks and showing it can significantly increase the BLEU score over the insertion-only framework.\nOur Insertion-Deletion Transformer consists of an insertion phase and a deletion phase that are executed iteratively.",

Input layer receives the signal, the output layer gives a decision or prediction about the input and the computation of the MLP is conducted in the hidden layers. In our system, we use 100 layers. For weight optimization, we use Limited-memory Broyden–Fletcher–Goldfarb–Shanno (LBFGS) optimization algorithm.\nSVM gives an optimal hyper-plane and it maximizes the margin between classes. We use Radial Basis Function (RBF) kernel in our system to make decision boundary curve-shaped. For decision function shape, we use the original one-vs-one (ovo) decision function.\nNBC is based on Bayes' Theorem which gives probability of an event occurrence based on some conditions related to that event. We use Multinomial Naive Bayes Classifier with smoothing parameter equals to 0.1. A zero probability cancels the effects of all the other probabilities.\nStochastic gradient descent optimizes an objective function with suitable smoothness properties BIBREF27. It selects few examples randomly instead of whole data for each iteration. We use 'L2' regularization for reduction of overfitting.\nGradient Boosting Classifier produces a prediction model consisting of weak prediction models. Gradient boosting uses decision trees. We use 100 boosting stages in this work.\nK-NN is a supervised classification and regression algorithm. It uses the neighbours of the given sample to identify its class. K determines the number of neighbours needed to be considered. We set the value of K equals to 13 in this work.\nRF is an ensemble learning technique. It constructs large number of decision trees during training and then predicts the majority class. We use 500 decision trees in the forest and \"entropy\" function to measure the quality of a split.\nWe use Radial Basis Function (RBF) kernel in our system to make decision boundary curve-shaped.",

We first provide necessary background on the neural tangent kernel (NTK) theory, which plays an important role in our analysis. Following a recent line of research, we define the covariance between two data point x, y ∈ R d as follows:\nfor all i, j ∈ [T K]. Based on the above definition, we impose the following assumption on the contexts generated by the adversary and the corresponding NTK matrix H.\nAssumption 1. Let H be defined in Eq(5). There exists λ 0 > 0 such that H ≥ λ 0 I. In addition, for any\nRemark 1. Compared to Algorithm 1 for linear bandits, our Algorithm 2 needs an additional Assumption 1 to guarantee the convergence. The assumption that the NTK matrix is positive definite has been considered in prior work on NTK which is a mild condition and also imposed in other related works. The assumption on contexts ensures that f (x i,t ; θ 0 ) = 0 for any\nThe NTK technique builds a connection between deep neural networks and kernel methods. It enables us to adapt some complexity measures for kernel methods to describe the complexity of the neural network through the notation of the effective dimensions as defined in. The effective dimension d of matrix H with regularization parameter λ is defined as d = log det(I+H/λ) log(1+T K/λ) . Using these notations, we are now ready to present the second main result of the paper. Let a * (t) = argmax i∈[K] E[r i,t ] be the optimal action at round t that maximizes the expected reward, we define the expected cumulative regret after T iterations as\nThen, we achieve the following upper regret bound for our Algorithm 2 by combining our EI techniques for LinEI with NTK techniques. A completed proof is provided in Supplementary Material.\nTheorem 2. Under Assumption 1, set the parameters in Algorithm 2 as λ = 1 + 1/T ,\nand the network width m satisfies m ≥ poly(γ, T, K, L, log(1/δ)), then with probability at least 1 − δ, the regret of Algorithm 2 is bounded as\nRemark 2. The regret bound depends on the parameter β. The best choice is β = 2 that tightens the regret. Theorem 2 implies the regret of NeuralEI is on the order of Õ( d√ T ). Similar to previous results, our results require a large value of m.

In 2020, a poll from the ICC declared it Tendulkar's best ODI inning.\n\nIn early 1998, while playing in an Australian tour of India, Tendulkar scored three consecutive centuries. The focus of the tour was the clash between Tendulkar and spinner Shane Warne, both at the peak of their careers. In the lead-up to the series, Tendulkar simulated scenarios in the nets with Laxman Sivaramakrishnan.

It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nWe will use the same training data as in [9] so that we can do fair comparisons with the performance of the LSTM models.",

During the course of a season (from August to May) each club plays the others twice (a double round-robin system), once at their home stadium and once at that of their opponents, for 38 games. Teams receive three points for a win and one point for a draw. No points are awarded for a loss. Teams are ranked by total points, then goal difference, and then goals scored. If still equal, teams are deemed to occupy the same position. If there is a tie for the championship, for relegation, or for qualification to other competitions, the head-to-head record between the tied teams is taken into consideration (points scored in the matches between the teams, followed by away goals in those matches.) If two teams are still tied, a play-off match at a neutral venue decides rank.\n\nPromotion and relegation\nA system of promotion and relegation exists between the Premier League and the EFL Championship. The three lowest placed teams in the Premier League are relegated to the Championship, and the top two teams from the Championship promoted to the Premier League, with an additional team promoted after a series of play-offs involving the third, fourth, fifth and sixth placed clubs. The number of clubs was reduced from 22 to 20 in 1995, when four teams were relegated from the league and only two teams promoted. The top flight had only been expanded to 22 teams at the start of the 1991–92 season – the year prior to the formation of the Premier League.\n\nOn 8 June 2006, FIFA requested that all major European leagues, including Italy's Serie A and Spain's La Liga, be reduced to 18 teams by the start of the 2007–08 season.

It begins the observance of Allhallowtide, the time in the liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed.\n\nOne theory holds that many Halloween traditions were influenced by Celtic harvest festivals, particularly the Gaelic festival Samhain, which are believed to have pagan roots. Some go further and suggest that Samhain may have been Christianized as All Hallow's Day, along with its eve, by the early Church. Other academics believe Halloween began solely as a Christian holiday, being the vigil of All Hallow's Day. Celebrated in Ireland and Scotland for centuries, Irish and Scottish immigrants took many Halloween customs to North America in the 19th century, and then through American influence Halloween had spread to other countries by the late 20th and early 21st century.\n\nPopular Halloween activities include trick-or-treating (or the related guising and souling), attending Halloween costume parties, carving pumpkins or turnips into jack-o'-lanterns, lighting bonfires, apple bobbing, divination games, playing pranks, visiting haunted attractions, telling scary stories, and watching horror or Halloween-themed films. Some people practice the Christian religious observances of All Hallows' Eve, including attending church services and lighting candles on the graves of the dead, although it is a secular celebration for others.

Our model integrates two components: (a) a generative dialog model that learns to represent conversational dynamics in an unsupervised fashion; and (b) a supervised component that fine-tunes this representation to forecast future events. Figure FIGREF13 provides an overview of the proposed architecture, henceforth CRAFT (Conversational Recurrent Architecture for ForecasTing).\nTerminology. For modeling purposes, we treat a conversation as a sequence of $N$ comments $C = \\lbrace c_1,\\dots ,c_N\\rbrace $. Each comment, in turn, is a sequence of tokens, where the number of tokens may vary from comment to comment. For the $n$-th comment ($1 \\le n \\le N)$, we let $M_n$ denote the number of tokens. Then, a comment $c_n$ can be represented as a sequence of $M_n$ tokens: $c_n = \\lbrace w_1,\\dots ,w_{M_n}\\rbrace $.\nGenerative component. For the generative component of our model, we use a hierarchical recurrent encoder-decoder (HRED) architecture BIBREF60, a modified version of the popular sequence-to-sequence (seq2seq) architecture BIBREF61 designed to account for dependencies between consecutive inputs. BIBREF23 showed that HRED can successfully model conversational context by encoding the temporal structure of previously seen comments, making it an ideal fit for our use case. Here, we provide a high-level summary of the HRED architecture, deferring deeper technical discussion to BIBREF60 and BIBREF23.\nAn HRED dialog model consists of three components: an utterance encoder, a context encoder, and a decoder. The utterance encoder is responsible for generating semantic vector representations of comments. It consists of a recurrent neural network (RNN) that reads a comment token-by-token, and on each token $w_m$ updates a hidden state $h^{\\text{enc}}$ based on the current token and the previous hidden state:\nwhere $f^{\\text{RNN}}$ is a nonlinear gating function (our implementation uses GRU BIBREF62). The final hidden state $h^{\\text{enc}}_M$ can be viewed as a vector encoding of the entire comment.\nRunning the encoder on each comment $c_n$ results in a sequence of $N$ vector encodings. A second encoder, the context encoder, is then run over this sequence:\nEach hidden state $h^{\\text{con}}_n$ can then be viewed as an encoding of the full conversational context up to and including the $n$-th comment. To generate a response to comment $n$, the context encoding $h^{\\text{con}}_n$ is used to initialize the hidden state $h^{\\text{dec}}_{0}$ of a decoder RNN. The decoder produces a response token by token using the following recurrence:\nwhere $f^{\\text{out}}$ is some function that outputs a probability distribution over words; we implement this using a simple feedforward layer. In our implementation, we further augment the decoder with attention BIBREF63, BIBREF64 over context encoder states to help capture long-term inter-comment dependencies. This generative component can be pre-trained using unlabeled conversational data.\nPrediction component. Given a pre-trained HRED dialog model, we aim to extend the model to predict from the conversational context whether the to-be-forecasted event will occur. Our predictor consists of a multilayer perceptron (MLP) with 3 fully-connected layers, leaky ReLU activations between layers, and sigmoid activation for output. For each comment $c_n$, the predictor takes as input the context encoding $h^{\\text{con}}_n$ and forwards it through the MLP layers, resulting in an output score that is interpreted as a probability $p_{\\text{event}}(c_{n+1})$ that the to-be-forecasted event will happen (e.g., that the conversation will derail).\nTraining the predictive component starts by initializing the weights of the encoders to the values learned in pre-training. The main training loop then works as follows: for each positive sample—i.e., a conversation containing an instance of the to-be-forecasted event (e.g., derailment) at comment $c_e$—we feed the context $c_1,\\dots ,c_{e-1}$ through the encoder and classifier, and compute cross-entropy loss between the classifier output and expected output of 1. Similarly, for each negative sample—i.e., a conversation where none of the comments exhibit the to-be-forecasted event and that ends with $c_N$—we feed the context $c_1,\\dots ,c_{N-1}$ through the model and compute loss against an expected output of 0.\nNote that the parameters of the generative component are not held fixed during this process; instead, backpropagation is allowed to go all the way through the encoder layers. This process, known as fine-tuning, reshapes the representation learned during pre-training to be more directly useful to prediction BIBREF55.\nWe implement the model and training code using PyTorch, and we are publicly releasing our implementation and the trained models together with the data as part of ConvoKit.\n\nWe now describe our general model for forecasting future conversational events. Our model integrates two components: (a) a generative dialog model that learns to represent conversational dynamics in an unsupervised fashion; and (b) a supervised component that fine-tunes this representation to forecast future events.",

Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.\n\nAuroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionisation and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles.",

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nIn the second architecture, we use TreeLSTM (Tai et al., 2015) to represent the input sentences in the form of a dependency tree.",

For the nfL6 dataset, the comparison of (1)'s was NAGM's 50% to CLSTM's 30%. ",
        "evidence": "NAGMWA is much better than the other methods except NAGM, since it generates answers whose conclusions and supplements as well as their combinations closely match the questions. Thus, conclusions and supplements in the answers are consistent with each other and avoid confusion made by several different conclusion-supplement answers assigned to a single non-factoid questions. Finally, NAGM is consistently superior to the conventional attentive encoder-decoders regardless of the metric. Its ROUGE-L and BLEU-4 scores are much higher than those of CLSTM. Thus, NAGM generates more fluent sentences by assessing the context from conclusion to supplement sentences in addition to the closeness of the question and sentences as well as that of the question and sentence combinations.\nThe experts asked questions, which were not included in our training datasets, to the AI system and rated the answers; one answer per question. The experts rated the answers as follows: (1) the content of the answer matched the question, and the grammar was okay; (2) the content was suitable, but the grammar was poor; (3) the content was not suitable, but the grammar was okay; (4) both the content and grammar were poor. Note that our evaluation followed the DUC-style strategy. Here, we mean “grammar” to cover grammaticality, non-redundancy, and referential clarity in the DUC strategy, whereas we mean the “content matched the questions” to refer to “focus” and “structure and coherence” in the DUC strategy. The evaluators were given more than a week to carefully evaluate the generated answers, so we consider that their judgments are reliable. Each expert evaluated 50 questions. We combined the scores of the experts by summing them. They did not know the identity of the system in the evaluation and reached their decisions independently.\nThese results indicate that the experts were much more satisfied with the outputs of NAGM than those of CLSTM. This is because, as can be seen in Table 7, NAGM generated longer and better question-related sentences than CLSTM did.

Second, the authors re-design the aggregation mechanism in \"compare aggregate\" to a two-staged CNN architecture which comprises word-level aggregation and sentence-level aggregation.",
        "evidence": "Many machine learning models in question answering tasks often involve matching mechanism. For example, in factoid question answering such as SQuAD BIBREF1 , one needs to match between query and corpus in order to find out the most possible fragment as answer. In multiple choice question answering, such as MC Test BIBREF2 , matching mechanism can also help make the correct decision.\nThe easiest way of matching is to calculate the cosine similarity between two vectors. It is generally done by two step: First, encode text into word vectors, sentence vectors or paragraph vectors. Second, simply calculate the cosine similarity between target vectors. This method performs well when applied to word-level matching. However, as for matching between sentences or paragraphs, a single vector is not sufficient to encode all the important information. In order to solve this problem, Wang and Jiang proposed a “compare-aggregate” BIBREF3 framework that performs word-level matching using multiple techniques followed by aggregation with convolutional neural network. In their work, they show that compare-aggregate framework can effectively match two sequences through a wide range.\nAlthough \"compare-aggregate\" matching mechanism performs well on multiple question answering tasks, it has two deficiencies. First, it tends to aggregate passively through the sequence rather than take the importance of each element into account. That is, \"compare aggregate\" model considers all the sequential contents equally. Second, \"compare aggregate\" can only take few neighboring elements into account at the same time because of the limitation of CNN kernel size.\nIn this paper, we propose Query-based Attention CNN (QACNN) to deal with the deficiencies above. First, we add query-based attention mechanism into original \"compare aggregate\" model. Moreover, We re-design the aggregation mechanism in \"compare aggregate\" to a two-staged CNN architecture which comprises word-level aggregation and sentence-level aggregation. In this way, QACNN can efficiently extract features cross sentences.\nOur model consists of three components: 1) The similarity mapping layer which converts the input passage, query and choice into feature representation and perform a similarity operation to each other. 2) The attention-based CNN matching network composed of a two-staged CNN focusing on word-level and sentence-level matching respectively. 3) The prediction layer which makes the final decision.\nThe main contributions of this work are three-fold. First, we introduce a two-staged CNN architecture which integrates information from word-level to sentence-level, and then from sentence-level to passage-level. Second, we introduce attention mechanism into this net. We use specially designed CNN structure and attention mechanism to recognize the pattern of similarity map and eventually identify specific syntactic structure of queries. By transforming passage-query feature into attention maps and applying it to passage-choice matching result, we reasonably give weight to every word in the passage. Lastly, our model reaches 79.99% accuracy on the MovieQA dataset which yields top 1 result on this dataset.\nFirst, we add query-based attention mechanism into original \"compare aggregate\" model.

Hence, on the analyses of the above popular word segmentation methods, we propose the morphologically motivated segmentation strategy that combines the morpheme segmentation and BPE for further improving the translation performance of NMT.\nCompared with the sentence of word surface forms, the corresponding sentence of stem units only contains the structure information without considering morphological information, which can make better generalization over inflectional variants of the same word and reduce data sparseness BIBREF8.

There are six different types of pieces in chess, including: Pawns, Rooks, Bishops, Knights, a Queen, and a King. Each of these pieces can move on the board in different ways. The goal of the game is to utilize your pieces to capture your opponent's king. In a game of chess, players alternate turns moving one piece at a time. When a player moves a piece, they are either positioning the piece on an open square where no other piece is currently on, or they are capturing an opponent's piece. To win a game of chess, players will balance strategically positioning their pieces and capturing their opponent's pieces. Doing so will allow a player to have the opportunity to put their opponent in a position called \"Checkmate\". When a player is checkmated, it means that their King is in an attacking line of one or more of their opponent's pieces and they have no legal moves to escape this attack.

        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nResults reported in Table 2 show no benefit from using a separate algorithm for binarization.",

        "evidence": "Rafael Nadal Parera (Catalan: [rəf(ə)ˈɛl nəˈðal pəˈɾeɾə], Spanish: [rafaˈel naˈðal paˈɾeɾa]; born 3 June 1986) is a Spanish professional tennis player. He is currently ranked world No. 14 in singles by the Association of Tennis Professionals (ATP). He has been ranked world No. 1 for 209 weeks, and has finished as the year-end No. 1 five times. He also holds the record for most consecutive weeks in the Top 10 of the ATP Rankings, having never left the Top 10 from April 2005 to March 2023, a total of 912 weeks. Nadal has won a joint-record 22 Grand Slam men's singles titles, including a record 14 French Open titles. He has won 92 ATP singles titles, including 36 Masters titles, with 63 of these on clay courts. Nadal is one of only two men to complete the Career Golden Slam in singles. His 81 consecutive wins on clay is the longest single-surface win streak in the Open Era.\n\nFor over a decade, Nadal has dominated men's tennis along with Roger Federer and Novak Djokovic as the Big Three, collectively considered by many to be the three greatest male tennis players of all time. At the start of his professional career, Nadal became one of the most successful teenagers in ATP Tour history, reaching the world No. 2 ranking and winning 16 titles before turning 20, including his first French Open and six Masters events. Nadal became the world No. 1 for the first time in 2008 after defeating Federer in a historic Wimbledon final, his first major victory off clay. He followed up his win with an Olympic singles gold at the 2008 Beijing Olympics. After defeating Djokovic in the 2010 US Open final, then-24-year-old Nadal became the youngest man in the Open Era to achieve the Career Grand Slam, and the first man to win majors on three different surfaces (hard, grass, and clay) in the same year (Surface Slam).\n\nAfter two injury-plagued seasons, Nadal made a stellar return in one of the greatest comeback seasons of all time in 2013; reaching 14 finals, winning two majors and five Masters events including the US Open Series sweep (Summer Slam). He continued his dominance at the French Open, securing six titles, two US Open titles, an Australian Open title, and an Olympic doubles gold at the 2016 Rio Olympics with Marc López. Nadal surpassed his joint-record with Djokovic and Federer for the most major men's singles titles at the 2022 Australian Open, and became one of four men in history to complete the double Career Grand Slam in singles. He appeared in the Top 10 of the ATP rankings continuously from April 2005 to March 2023 – a record spanning 18 years.\n\nAs a vigorous left-handed player, one of Nadal's main strengths is his forehand, which he hits with extremely heavy topspin at difficult angles. He is one of the best at breaking serve, regularly appearing among the tour leaders in percentage of return games, return points, and break points won. Nadal has won the Stefan Edberg Sportsmanship Award five times, and was the Laureus World Sportsman of the Year in 2011 and 2021. He is also a recipient of the Grand Cross of the Order of Dos De Mayo, the Grand Cross of Naval Merit, and the Medal of the City of Paris. Representing Spain, he has won two Olympic gold medals, and led the nation to four Davis Cup titles. Nadal has also opened a tennis academy in Mallorca, and is an active philanthropist.",

        "question": "Where is the density estimation result for longrun EBM?",
        "answer": "Our density estimation results are the longrun FID scores in Table 4 and visualizations of longrun samples in Figure 11. Please refer to the general statement for our explanation of why we believe these are an appropriate evaluation to investigate density modeling.",
        "evidence": "Prior work has suggested that persistent learning is the most effective method for learning a valid EBM density. Furthermore, works that learn a valid density have avoided rejuvenation because the incorporation of newly rejuvenated samples into the persistent bank ensures that EBM updates will always include samples that are not at the steady-state. However, persistent learning without rejuvenation has shortcomings mentioned in Section 3. We present hypothesized conditions for learning a valid density that motivate the design of our MCMC initialization:\n• After a certain point in training, all samples used to update the EBM must be approximate steadystate samples of the current model p(x; θ). • Persistent samples that are newly rejuvenated (up to about 50K Langevin steps since rejuvenation, and possibly many more) cannot be approximate steady-state samples for any known rejuvenation sources, including data, generators, and noise. • Persistent samples that have undergone sufficiently many lifetime Langevin updates for a model whose weights are changing very slowly can be approximate steady-state samples.\nFigure: Visualization of our longrun initializatin procedure. Newly rejuvenated samples must remain the the burnin bank until they have approach the model steady-state, at which point they move to the update bank to be used for model gradients.\nBoth the second and third point are corroborated by prior work as well as our own observations. The third point means that persistent states updated with shortrun Langevin can eventually act as longrun Langevin samples if the optimizer learning rate is small, because the EBM samples in previous timesteps are essentially samples from the current EBM.\nLearning a valid density that includes rejuvenation while satisfying the conditions above requires separating the newly rejuvenated samples from samples that are used to update the EBM. This leads us to introduce two persistent image banks: one for newly rejuvenated samples, and one for samples that will be used to update the EBM. Samples in the newly rejuvenated bank that have been updated sufficiently many times will eventually replace samples from the bank used to update the EBM, at which point newly rejuvenated states will be added to the burn-in bank. Figure shows a visualization of the MCMC initialization method. As in Section 3, we will use a pre-trained generator to efficiently obtain high-quality rejuvenated samples so that the generation process is fully synthetic, although data samples could be used as well. Our goal is to preserve the sample quality for an arbitrary number of MCMC steps. We note that this is a sufficient but not necessary condition for learning a valid EBM density. Nonetheless, stable sampling is an important step towards rigorous probabilistic EBMs. Even with our improved initialization, we find that extremely longrun trajectories of 1 million or more MCMC steps still tend to oversaturate, although to a much lesser degree. To further stabilize the appearance of extremely longrun Langevin samples, we include prior energy terms in the model. Our longrun EBMs have the form\nwhere U (x; θ) is the model whose weights are updated, U 0 (x; θ 0 ) is a prior EBM with fixed weights θ 0 and σ is a parameter controlling the strength of a Gaussian prior. We used a prior EBM in a shortrun manner. The role of the prior EBM is to provide some stability but also to provide a tendency to oversaturate at longer trajectories so that the current EBM learns to correct oversaturation. The Gaussian prior is meant to discourage unbounded activations outside of the image hypercube. Further discussion is in Appendix H. We find that including both of these terms significantly improves the ability to learn quality synthesis over long trajectories.\nTable 4: FID for 5K samples after 100K Langevin and 1M Langevin steps. FID remains stable over long trajectories.****Figure 13: Longrun samples at 100,000 steps and extremely longrun samples at 1 million steps\nfor EBMs trained on three datasets. Our initialization is able to preserve a high degree of realism over the first 100K steps, and a reasonable degree of realism over very long trajectories. While oversaturation and distortion is noticeable for some samples using 1M steps, many samples have reasonable appearance and there is high diversity. Our method makes significant progress towards aligning longrun samples with high-quality samples from training to ensure that the model is a valid\ndensity",

In 1948, he won the 1948 Senate election in Texas after a narrow and controversial victory in the Democratic Party's primary. He was appointed to the position of Senate Majority Whip in 1951. He became the Senate Democratic leader in 1953 and majority leader in 1954. In 1960 Johnson ran for the Democratic nomination for president. Ultimately, Senator Kennedy bested Johnson and his other rivals for the nomination, then surprised many by offering to make Johnson his vice presidential running mate. The Kennedy-Johnson ticket won in the 1960 presidential election. Vice President Johnson assumed the presidency on November 22, 1963, after President Kennedy was assassinated. The following year Johnson was elected to the presidency when he won in a landslide against Arizona Senator Barry Goldwater, receiving 61.1% of the popular vote in the 1964 presidential election, the largest share won by any presidential candidate since the 1820 election.\n\nJohnson's domestic policy was aimed at expanding civil rights, public broadcasting, access to healthcare, aid to education and the arts, urban and rural development, and public services. In 1964 Johnson coined the term the \"Great Society\" to describe these efforts. In addition, he sought to create better living conditions for low-income Americans by spearheading a campaign unofficially called the \"War on Poverty\". As part of these efforts, Johnson signed the Social Security Amendments of 1965, which resulted in the creation of Medicare and Medicaid. Johnson followed his predecessor's actions in bolstering NASA and made the Apollo Program a national priority. He enacted the Higher Education Act of 1965 which established federally insured student loans. Johnson signed the Immigration and Nationality Act of 1965 which laid the groundwork for U.S. immigration policy today. Johnson's opinion on the issue of civil rights put him at odds with other white, southern Democrats. His civil rights legacy was shaped by signing the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Civil Rights Act of 1968. During his presidency, the American political landscape transformed significantly, as white southerners who were once staunch Democrats began moving to the Republican Party and black voters began moving to the Democratic Party. Because of his domestic agenda, Johnson's presidency marked the peak of modern liberalism in the United States.\n\nJohnson's presidency took place during the Cold War, thus his foreign policy prioritized containment of communism. Prior to his presidency, the U.S. was already involved in the Vietnam War, supporting South Vietnam against the communist North. Following a naval skirmish in 1964 between the United States and North Vietnam, Congress passed the Gulf of Tonkin Resolution, which granted Johnson the power to launch a full-scale military intervention in South East Asia. The number of American military personnel in Vietnam increased dramatically, and casualties soared among U.S. soldiers and Vietnamese civilians. Johnson also expanded military operations in neighboring Laos to destroy North Vietnamese supply lines. In 1968, the communist Tet Offensive inflamed the anti-war movement, especially among draft-age students on university campuses, and public opinion turned against America's involvement in the war. In Europe, Johnson's administration continued to promote and foster Western European political and economic cooperation and integration as his predecessors had.\n\nAt home, Johnson faced further troubles with race riots in major cities and increasing crime rates. His political opponents seized the opportunity and raised demands for \"law and order\" policies. Johnson began his presidency with near-universal support, but his approval declined throughout his presidency as the public became frustrated with both the Vietnam War and domestic unrest. Johnson initially sought to run for re-election; however, following disappointing results in the New Hampshire primary he withdrew his candidacy. The war was a major election issue and the 1968 presidential election saw Republican candidate Richard Nixon defeat Johnson's vice president Hubert Humphrey. At the end of his presidency in 1969, Johnson returned to his Texas ranch, published his memoirs, and in other respects kept a low profile until he died of a heart attack in 1973.\n\nJohnson is one of the most controversial presidents in American history. Public opinion and academic assessments of his legacy have fluctuated greatly ever since his death. Historians and scholars rank Johnson in the upper tier because of his accomplishments regarding domestic policy. His administration passed many major laws that made substantial changes in civil rights, health care, welfare, and education. Conversely, Johnson is strongly criticized for his foreign policy, namely escalating American involvement in the Vietnam War.",

In 1967, the country co-founded the Association of Southeast Asian Nations (ASEAN). Race riots broke out once more in 1969. Lee Kuan Yew's emphasis on rapid economic growth, support for business entrepreneurship, and limitations on internal democracy shaped Singapore's policies for the next half-century. Economic growth continued throughout the 1980s, with the unemployment rate falling to 3% and real GDP growth averaging at about 8% up until 1999. During the 1980s, Singapore began to shift towards high-tech industries, such as the wafer fabrication sector, in order to remain competitive as neighbouring countries began manufacturing with cheaper labour.

Ideologically a Marxist–Leninist and Cuban nationalist, he also served as the first secretary of the Communist Party of Cuba from 1961 until 2011. Under his administration, Cuba became a one-party communist state; industry and business were nationalized, and socialist reforms were implemented throughout society.\n\nBorn in Birán, the son of a wealthy Spanish farmer, Castro adopted leftist and anti-imperialist ideas while studying law at the University of Havana. After participating in rebellions against right-wing governments in the Dominican Republic and Colombia, he planned the overthrow of Cuban President Fulgencio Batista, launching a failed attack on the Moncada Barracks in 1953. After a year's imprisonment, Castro travelled to Mexico where he formed a revolutionary group, the 26th of July Movement, with his brother Raúl Castro and Ernesto \"Che\" Guevara. Returning to Cuba, Castro took a key role in the Cuban Revolution by leading the Movement in a guerrilla war against Batista's forces from the Sierra Maestra. After Batista's overthrow in 1959, Castro assumed military and political power as Cuba's prime minister. The United States came to oppose Castro's government and unsuccessfully attempted to remove him by assassination, economic embargo, and counter-revolution, including the Bay of Pigs Invasion of 1961. Countering these threats, Castro aligned with the Soviet Union and allowed the Soviets to place nuclear weapons in Cuba, resulting in the Cuban Missile Crisis – a defining incident of the Cold War – in 1962.",

BioIE systems aim to extract information from a wide spectrum of articles including medical literature, biological literature, electronic health records, etc. that can be used by clinicians and researchers in the field. Often the outputs of BioIE systems are used to assist in the creation of databases, or to suggest new paths for research. For example, a ranked list of interacting proteins that are extracted from biomedical literature, but are not present in existing databases, can allow researchers to make informed decisions about which protein/gene to study further. Interactions between drugs are necessary for clinicians who simultaneously administer multiple drugs to their patients. A database of diseases, treatments and tests is beneficial for doctors consulting in complicated medical cases.\nThe main problems in BioIE are similar to those in Information Extraction:\nThis paper discusses, in each section, various methods that have been adopted to solve the listed problems. Each section also highlights the difficulty of Information Extraction tasks in the biomedical domain.\nThis paper is intended as a primer to Biomedical Information Extraction for current NLP researchers.

        "question": "Does the Transformerbased concat22 outperform the RNN-based concat22?",
        "answer": "No, it doesn't.",
        "evidence": "The BLEU scores in Table TABREF30 show a moderate improvement for most context-aware systems. This suggests that the architectural changes for the context-aware models do not degrade overall translation quality. The contrastive evaluation on our test set on the other hand shows a clear increase in the accuracy of pronoun translation: The best model s-hier-to-2.tied achieves a total of +16 percentage points accuracy on the test set over the baseline, see Table TABREF31 .\nTable TABREF32 shows that context-aware models perform better than the baseline when the antecedent is outside the current sentence. In our experiments, all context-aware models consider one preceding sentence as context. The evaluation according to the distance of the antecedent in Table TABREF35 confirms that the subset of sentences with antecedent distance 1 benefits most from the tested context-aware models (up to +20 percentage points accuracy). However, we note two surprising patterns:\nThe first observation can be explained by the distribution of German pronouns in the test set. The further away the antecedent, the higher the percentage of it INLINEFORM0 es cases, which are the majority class, and thus the class that will be predicted most often if evidence for other classes is lacking. We speculate that this is due to our more permissive extraction heuristics for it INLINEFORM1 es.\nWe attribute the second observation to the existence of coreference chains where the preceding sentence contains a pronoun that refers to the same nominal antecedent as the pronoun in the current sentence. Consider the example in Table TABREF36 : The nominal antecedent of it in the current sentence is door, Tür in German with feminine gender. The nominal antecedent occurs two sentences before the current sentence, but the German sentence in between contains the pronoun sie, which is a useful signal for the context-aware models, even though they cannot know the nominal antecedent.\nNote that only models aware of target-side context can benefit from such circumstances: The s-hier models as well as the Transformer model by BIBREF8 only see source side context, which results in lower accuracy if the distance to the antecedent is INLINEFORM0 1, see Table TABREF35 .\nWhile such coreference chains complicate the interpretation of the results, we note that improvements on inter-sentential anaphora with antecedent distance INLINEFORM0 are relatively small (compared to distance 1), and that performance is still relatively poor (especially for the minority classes er and sie). We encourage evaluation of wider-context models on this subset, which is still large thanks to the size of the full test set.\nRegarding the comparison of different context-aware architectures, our results demonstrate the effectiveness of parameter sharing between the main encoder (or decoder) and the contextual encoder. We observe an improvement of 5 percentage points from s-hier-to-2 to s-hier-to-2.tied, and 4 percentage points from s-t-hier to s-t-hier.tied. Context encoders introduce a large number of extra parameters, while inter-sentential context is only relevant for a relatively small number of predictions. We hypothesize that the training signal is thus too weak to train a strong contextual encoder in an end-to-end fashion without parameter sharing. Our results also confirm the finding by BIBREF9 that multi-encoder architectures, specifically s-hier-to-2(.tied), can outperform a simple concatenation system in the translation of coreferential pronouns.\nThe Transformer-based models perform strongest on pronouns with intra-segmental antecedent, outperforming the recurrent baseline by 9–18 percentage points. This is likely an effect of increased model depth and the self-attentional architecture in this set of experiments. The model by BIBREF8 only uses source context, and outperforms the most comparable RNN system, s-hier.tied. However, the Transformer-based concat22 slightly underperforms the RNN-based concat22, and we consider it future research how to better exploit target context with Transformer-based models.\nHowever, the Transformerbased concat22 slightly underperforms the RNN-based concat22, and we consider it future research how to better exploit target context with Transformer-based models.",

The labels A0 and A1 correspond to the PropBank annotations BIBREF0 .\nAs the need for SRL arises in different domains and languages, the existing manually annotated corpora become insufficient to build supervised systems. This has motivated work on unsupervised SRL BIBREF1 , BIBREF2 , BIBREF3 . Previous work has indicated that unsupervised systems could benefit from the word alignment information in parallel text in two or more languages BIBREF4 , BIBREF5 , BIBREF6 . For example, consider the German translation of sentence INLINEFORM0 :\n INLINEFORM0 \nIf sentences INLINEFORM0 and INLINEFORM1 have the word alignments: Mike-Mike, written-geschrieben, and book-Buch, the system might be able to predict A1 for Buch, even if there is insufficient information in the monolingual German data to learn this assignment. Thus, in languages where the resources are sparse or not good enough, or the distributions are not informative, SRL systems could be made more accurate by using parallel data with resource rich or more amenable languages.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages.

        "answer": "They use either the pre-trained BERT weights1 , or the weights from a BERT fine-tuned on the task-specific dataset on a segment-level.",
        "evidence": "Because our work builds heavily upon BERT, we provide a brief summary of its features. BERT is built upon the Transformer architecture BIBREF0, which uses self-attention, feed-forward layers, residual connections and layer normalization as the main building blocks. It has two pre-training objectives:\nMasked language modelling - some of the words in a sentence are being masked and the model has to predict them based on the context (note the difference from the typical autoregressive language model training objective);\nNext sentence prediction - given two input sequences, decide whether the second one is the next sentence or not.\nBERT has been shown to beat the state-of-the-art performance on 11 tasks with no modifications to the model architecture, besides adding a task-specific output layer BIBREF1. We follow same procedure suggested in BIBREF1 for our tasks. Fig. FIGREF8 shows the BERT model for classification. We obtain two kinds of representation from BERT: pooled output from last transformer block, denoted by H, and posterior probabilities, denoted by P. There are two variants of BERT - BERT-Base and BERT-Large. In this work we are using BERT-Base for faster training and experimentation, however, our methods are applicable to BERT-Large as well. BERT-Base and BERT-Large are different in model parameters such as number of transformer blocks, number of self-attention heads. Total number of parameters in BERT-Base are 110M and 340M in BERT-Large.\nBERT suffers from major limitations in terms of handling long sequences. Firstly, the self-attention layer has a quadratic complexity $O(n^2)$ in terms of the sequence length $n$ BIBREF0. Secondly, BERT uses a learned positional embeddings scheme BIBREF1, which means that it won't likely be able to generalize to positions beyond those seen in the training data.\nTo investigate the effect of fine-tuning BERT on task performance, we use either the pre-trained BERT weights, or the weights from a BERT fine-tuned on the task-specific dataset on a segment-level (i.e. we preserve the original label but fine-tune on each segment separately instead of on the whole text sequence). We compare these results to using the fine-tuned segment-level BERT predictions directly as inputs to the next layer.\nGiven that BERT is limited to a particular input length, we split the input sequence into segments of a fixed size with overlap. For each of these segments, we obtain H or P from BERT model. We then stack these segment-level representations into a sequence, which serves as input to a small (100-dimensional) LSTM layer. Its output serves as a document embedding. Finally, we use two fully connected layers with ReLU (30-dimensional) and softmax (the same dimensionality as the number of classes) activations to obtain the final predictions.\nWith this approach, we overcome BERT's computational complexity, reducing it to $O(n/k * k^2) = O(nk)$ for RoBERT, with $k$ denoting the segment size (the LSTM component has negligible linear complexity $O(k)$). The positional embeddings are also no longer an issue.\nGiven that Transformers' edge over recurrent networks is their ability to effectively capture long distance relationships between words in a sequence BIBREF0, we experiment with replacing the LSTM recurrent layer in favor of a small Transformer model (2 layers of transformer building block containing self-attention, fully connected, etc.). To investigate if preserving the information about the input sequence order is important, we also build a variant of ToBERT which learns positional embeddings at the segment-level representations (but is limited to sequences of length seen during the training).\nToBERT's computational complexity $O(\\frac{n^2}{k^2})$ is asymptotically inferior to RoBERT, as the top-level Transformer model again suffers from quadratic complexity in the number of segments. However, in practice this number is much smaller than the input sequence length (${\\frac{n}{k}} << n$), so we haven't observed performance or memory issues with our datasets.\nTo investigate the effect of fine-tuning BERT on task performance, we use either the pre-trained BERT weights1 , or the weights from a BERT fine-tuned on the task-specific dataset on a segment-level (i.e. we preserve the original label but fine-tune on each segment separately instead of on the whole text sequence).",

Reforming the pension system was a significant part of his platform for election in 2017, with initial protests and transport strikes in late 2019, prior to the COVID-19 pandemic which saw Macron delay the reforms further. Raising the retirement age was not part of these initial reforms, but another \"plan to unify the complex French pension system\" by \"getting rid of the 42 special regimes for sectors ranging from rail and energy workers to lawyers was crucial to keep the system financially viable\". On 26 October 2022, Macron announced in a televised interview that pension reform scheduled for 2023 intended to raise the retirement age to 65, specifically that the minimum retirement age to be able to receive a full pension would be \"gradually increased\" from 62 to 65 by 2031, by three months per year from September 2023 to September 2030. Furthermore, the number of years that contributions would need to be made to qualify for the full state pension would increase from 42 to 43 in 2027, meaning that some may have to work to 67 – the year at which a person is automatically able to receive a state pension from. In addition to this, France's 42 separate pension schemes would be \"streamlined\". Macron clarified he would be willing to \"discuss the retirement age with unions and make potential amendments\", and that not implementing the reforms would lead to a reduction in the size of pensions.\n\nDetails of the reforms were scheduled to be revealed on 15 December 2022, but were delayed further to 10 January 2023, as a courtesy to the Greens and Republicans who were in the midst of electing new leaders; postponing the reforms to allow Macron to consult with said new leaders before revealing said details.",

The task is to generate an inflected word form given its lemma and the context in which it occurs.\nMorphological (re)inflection from context is of particular relevance to the field of computational linguistics: it is compelling to estimate how well a machine-learned system can capture the morphosyntactic properties of a word given its context, and map those properties to the correct surface form for a given lemma.\nThere are two tracks of Task 2 of CoNLL–SIGMORPHON 2018: in Track 1 the context is given in terms of word forms, lemmas and morphosyntactic descriptions (MSD); in Track 2 only word forms are available. See Table TABREF1 for an example. Task 2 is additionally split in three settings based on data size: high, medium and low, with high-resource datasets consisting of up to 70K instances per language, and low-resource datasets consisting of only about 1K instances.\nThe baseline provided by the shared task organisers is a seq2seq model with attention (similar to the winning system for reinflection in CoNLL–SIGMORPHON 2016, BIBREF1 ), which receives information about context through an embedding of the two words immediately adjacent to the target form. We use this baseline implementation as a starting point and achieve the best overall accuracy of 49.87 on Task 2 by introducing three augmentations to the provided baseline system: (1) We use an LSTM to encode the entire available context; (2) We employ a multi-task learning approach with the auxiliary objective of MSD prediction; and (3) We train the auxiliary component in a multilingual fashion, over sets of two to three languages.\nIn analysing the performance of our system, we found that encoding the full context improves performance considerably for all languages: 11.15 percentage points on average, although it also highly increases the variance in results. Multi-task learning, paired with multilingual training and subsequent monolingual finetuning, scored highest for five out of seven languages, improving accuracy by another 9.86% on average.\nThe task is to generate an inflected word form given its lemma and the context in which it occurs.",

        "evidence": "",
        "answer": "In cancer, the genomes of affected cells are rearranged in complex or even unpredictable ways. Massive sequencing efforts are used to identify previously unknown point mutations in a variety of genes in cancer. Bioinformaticians continue to produce specialized automated systems to manage the sheer volume of sequence data produced, and they create new algorithms and software to compare the sequencing results to the growing collection of human genome sequences and germline polymorphisms. New physical detection technologies are employed, such as oligonucleotide microarrays to identify chromosomal gains and losses (called comparative genomic hybridization), and single-nucleotide polymorphism arrays to detect known point mutations. These detection methods simultaneously measure several hundred thousand sites throughout the genome, and when used in high-throughput to measure thousands of samples, generate terabytes of data per experiment. Again the massive amounts and new types of data generate new opportunities for bioinformaticians. The data is often found to contain considerable variability, or noise, and thus Hidden Markov model and change-point analysis methods are being developed to infer real copy number changes.\n\nTwo important principles can be used in the analysis of cancer genomes bioinformatically pertaining to the identification of mutations in the exome. First, cancer is a disease of accumulated somatic mutations in genes. Second cancer contains driver mutations which need to be distinguished from passengers.\n\nWith the breakthroughs that this next-generation sequencing technology is providing to the field of Bioinformatics, cancer genomics could drastically change. These new methods and software allow bioinformaticians to sequence many cancer genomes quickly and affordably. This could create a more flexible process for classifying types of cancer by analysis of cancer driven mutations in the genome. Furthermore, tracking of patients while the disease progresses may be possible in the future with the sequence of cancer samples.\n\nAnother type of data that requires novel informatics development is the analysis of lesions found to be recurrent among many tumors.",

Twitch is operated by Twitch Interactive, a subsidiary of Amazon.com, Inc. It was introduced in June 2011 as a spin-off of the general-interest streaming platform Justin.tv. Content on the site can be viewed either live or via video on demand. The games shown on Twitch's current homepage are listed according to audience preference and include genres such as real-time strategy games (RTS), fighting games, racing games, and first-person shooters.\n\nThe popularity of Twitch eclipsed that of its general-interest counterpart. In October 2013, the website had 45 million unique viewers, and by February 2014, it was considered the fourth-largest source of peak Internet traffic in the United States. At the same time, Justin.tv's parent company was re-branded as Twitch Interactive to represent the shift in focus – Justin.tv was shut down in August 2014. That month, the service was acquired by Amazon for US$970 million, which later led to the introduction of synergies with the company's subscription service Amazon Prime. Twitch acquired Curse LLC in 2016, an operator of online video gaming communities and introduced means to purchase games through links on streams along with a program allowing streamers to receive commissions on the sales of games that they play.\n\nBy 2015, Twitch had more than 100 million viewers per month. In 2017, Twitch remained the leading live streaming video service for video games in the US, and had an advantage over YouTube Gaming, which shut down its standalone app in May 2019.

Twitter activity consists of short posts called tweets which are limited to 140 characters. Retweets, where users repost a tweet to spread its content, were not considered. (The spread of causal statements will be considered in future work.) We considered only English-language tweets for this study. To avoid cross-language effects, we kept only tweets with a user-reported language of `English' and, as a second constraint, individual tweets needed to match more English stopwords than any other language's set of stopwords. Stopwords considered for each language were determined using NLTK's database BIBREF29 . A tweet will be referred to as a `document' for the rest of this work.\nCausal documents were chosen to contain one occurrence only of the exact unigrams: `caused', `causing', or `causes'. The word `cause' was not included due to its use as a popular contraction for `because'. One `cause-word' per document restricted the analysis to single relationships between two relata. Documents that contain bidirectional words (`associate', `relate', `connect', `correlate', and any of their stems) were also not selected for analysis. This is because our focus is on causality, an inherently one-sided relationship between two objects. We also did not consider additional synonyms of these cause words, although that could be pursued for future work. Control documents were also selected. These documents did not contain any of `caused', `causing', or `causes', nor any bidirectional words, and are further matched temporally to obtain the same number of control documents as causal documents in each fifteen-minute period during 2013. Control documents were otherwise selected randomly; causal synonyms may be present. The end result of this procedure identified 965,560 causal and 965,560 control documents.

Our plan for the day was to infiltrate the Massif des Maures area and search for one of France's most endangered reptiles-- the western Hermann's tortoise.  The first stop of our quest was Le Village de Tortues (the Tortoise Village), a tortoise rehabilitation center near the town of Gonfaron.

Only through quick thinking and improvisation were we able to acquire the vital background information we needed. Okay - we utilized the signs provided for British visitors. For many people, the word tortoise invokes thoughts of giant four-foot-long Galapagos tortoises. Western Hermann's tortoises, on the other hand, are small, reaching a maximum length of eight inches.

        "question": "Given these paragraphs about Multiomics, what is a typical advantage of single-cell multiomics versus bulk analysis?",
        "evidence": "Multiomics, multi-omics, integrative omics, \"panomics\" or \"pan-omics\" is a biological analysis approach in which the data sets are multiple \"omes\", such as the genome, proteome, transcriptome, epigenome, metabolome, and microbiome (i.e., a meta-genome and/or meta-transcriptome, depending upon how it is sequenced); in other words, the use of multiple omics technologies to study life in a concerted way. By combining these \"omes\", scientists can analyze complex biological big data to find novel associations between biological entities, pinpoint relevant biomarkers and build elaborate markers of disease and physiology. In doing so, multiomics integrates diverse omics data to find a coherently matching geno-pheno-envirotype relationship or association. The OmicTools service lists more than 99 softwares related to multiomic data analysis, as well as more than 99 databases on the topic.\n\nSystems biology approaches are often based upon the use of panomic analysis data. The American Society of Clinical Oncology (ASCO) defines panomics as referring to \"the interaction of all biological functions within a cell and with other body functions, combining data collected by targeted tests ... and global assays (such as genome sequencing) with other patient-specific information.\"\n\nSingle-cell multiomics\nA branch of the field of multiomics is the analysis of multilevel single-cell data, called single-cell multiomics. This approach gives us an unprecedent resolution to look at multilevel transitions in health and disease at the single cell level. An advantage in relation to bulk analysis is to mitigate confounding factors derived from cell to cell variation, allowing the uncovering of heterogeneous tissue architectures.\n\nMethods for parallel single-cell genomic and transcriptomic analysis can be based on simultaneous amplification or physical separation of RNA and genomic DNA. They allow insights that cannot be gathered solely from transcriptomic analysis, as RNA data do not contain non-coding genomic regions and information regarding copy-number variation, for example. An extension of this methodology is the integration of single-cell transcriptomes to single-cell methylomes, combining single-cell bisulfite sequencing to single cell RNA-Seq. Other techniques to query the epigenome, as single-cell ATAC-Seq and single-cell Hi-C also exist.\n\nA different, but related, challenge is the integration of proteomic and transcriptomic data. One approach to perform such measurement is to physically separate single-cell lysates in two, processing half for RNA, and half for proteins. The protein content of lysates can be measured by proximity extension assays (PEA), for example, which use DNA-barcoded antibodies. A different approach uses a combination of heavy-metal RNA probes and protein antibodies to adapt mass cytometry for multiomic analysis.\n\nMultiomics and machine learning\nIn parallel to the advances in highthroughput biology, machine learning applications to biomedical data analysis are flourishing. The integration of multi-omics data analysis and machine learning has led to the discovery of new biomarkers. For example, one of the methods of the mixOmics project implements a method based on sparse Partial Least Squares regression for selection of features (putative biomarkers).\n\n\nhttps://en.wikipedia.org/wiki/Multiomics",

        "question": "Given the following summary of the book \"Human Compatible\" by Stuart Russell, what is the author's proposal to overcome the limitations of the standard approach for developing AI?",
        "evidence": "Russell begins by asserting that the standard model of AI research, in which the primary definition of success is getting better and better at achieving rigid human-specified goals, is dangerously misguided. Such goals may not actually reflect what human designers intend, such as by failing to take into account any human values not included in the goals. If an AI developed according to the standard model were to become superintelligent, it would likely not fully reflect human values and could be catastrophic to humanity. Russell asserts that precisely because the timeline for developing human-level or superintelligent AI is highly uncertain, safety research should be begun as soon as possible, as it is also highly uncertain how long it would take to complete such research.\n\nRussell argues that continuing progress in AI capability is inevitable because of economic pressures. Such pressures can already be seen in the development of existing AI technologies such as self-driving cars and personal assistant software. Moreover, human-level AI could be worth many trillions of dollars. Russell then examines the current debate surrounding AI risk. He offers refutations to a number of common arguments dismissing AI risk and attributes much of their persistence to tribalism—AI researchers may see AI risk concerns as an \"attack\" on their field. Russell reiterates that there are legitimate reasons to take AI risk concerns seriously and that economic pressures make continued innovation in AI inevitable.\n\nRussell then proposes an approach to developing provably beneficial machines that focuses on deference to humans. Unlike in the standard model of AI, where the objective is rigid and certain, this approach would have the AI's true objective remain uncertain, with the AI only approaching certainty about it as it gains more information about humans and the world. This uncertainty would, ideally, prevent catastrophic misunderstandings of human preferences and encourage cooperation and communication with humans. Russell concludes by calling for tighter governance of AI research and development as well as cultural introspection about the appropriate amount of autonomy to retain in an AI-dominated world.",

        "question": "In the method of Davidson et al., what kind of classifier was used to differentiate hate speech from offensive language?",
        "answer": "A classifier that involves naive Bayes, decision trees and SVM.",
        "evidence": "Simple word-based approaches, if used for blocking the posting of text or blacklisting users, not only fail to identify subtle offensive content, but they also affect the freedom of speech and expression. The word ambiguity problem – that is, a word can have different meanings in different contexts – is mainly responsible for the high false positive rate in such approaches. Ordinary NLP approaches on the other hand, are ineffective to detect unusual spelling, experienced in user-generated comment text. This is best known as the spelling variation problem, and it is caused either by unintentional or intentional replacement of single characters in a token, aiming to obfuscate the detectors.\nIn general, the complexity of the natural language constructs renders the task quite challenging. The employment of supervised learning classification methods for hate speech detection is not new. BIBREF6 reported performance for a simple LSTM classifier not better than an ordinary SVM, when evaluated on a small sample of Facebook data for only 2 classes (Hate, No-Hate), and 3 different levels of strength of hatred. BIBREF7 described another way of detecting offensive language in tweets, based on some supervised model. They differentiate hate speech from offensive language, using a classifier that involves naive Bayes, decision trees and SVM. Also, BIBREF8 attempted to discern abusive content with a supervised model combining various linguistic and syntactic features in the text, considered at character uni-gram and bi-gram level, and tested on Amazon data. In general, we can point out the main weaknesses of NLP-based models in their non-language agnostic nature and the low scores in detection.\nUnsupervised learning approaches are quite common for detecting offensive messages in text by applying concepts from NLP to exploit the lexical syntactic features of sentences BIBREF9 , or using AI-solutions and bag-of-words based text-representations BIBREF10 . The latter is known to be less effective for automatic detection, since hatred users apply various obfuscation tricks, such as replacing a single character in offensive words. For instance, applying a binary classifier onto a paragraph2vec representation of words has already been attempted on Amazon data in the past BIBREF11 , but it only performed well on a binary classification problem. Another unsupervised learning based solution is the work by BIBREF12 , in which the authors proposed a set of criteria that a tweet should exhibit in order to be classified as offensive. They also showed that differences in geographic distribution of users have only marginal effect on the detection performance. Despite the above observation, we explore other features that might be possible to improve the detection accuracy in the solution outlined below.\nThe work by BIBREF5 applied a crowd-sourced solution to tackle hate-speech, with the creation of an additional dataset of annotations to extend the existing corpus. The impact of the experience of annotators in the classification performance was investigated. The work by BIBREF13 dealt with the classification problem of tweets, but their interest was on sexism alone, which they distinguished into `Hostile', `Benevolent' or `Other'. While the authors used the dataset of tweets from BIBREF12 , they treated the existing `Sexism' tweets as being of class `Hostile', while they collected their own tweets for the `Benevolent' class, on which they finally applied the FastText by BIBREF14 , and SVM classification.\n BIBREF15 approached the issue with a supervised learning model that is based on a neural network. Their method achieved higher score over the same dataset of tweets than any unsupervised learning solution known so far. That solution uses an LSTM model, with features extracted by character n-grams, and assisted by Gradient Boosted Decision Trees. Convolution Neural Networks (CNN) has also been explored as a potential solution in the hate-speech problem in tweets, with character n-grams and word2vec pre-trained vectors being the main tools. For example, BIBREF16 transformed the classification into a 2-step problem, where abusive text first is distinguished from the non-abusive, and then the class of abuse (Sexism or Racism) is determined. BIBREF17 employed pre-trained CNN vectors in an effort to predict four classes. They achieved slightly higher F-score than character n-grams.\nIn spite of the high popularity of NLP approaches in hate-speech classification BIBREF3 , we believe there is still a high potential for deep learning models to further contribute to the issue. At this point it is also relevant to note the inherent difficulty of the challenge itself, which can be clearly noted by the fact that no solution thus far has been able to obtain an F-score above 0.93.\nDavidson et al.

Similar studies BIBREF15 , BIBREF16 , BIBREF17 , BIBREF10 , BIBREF11 have explored the existence of stable counting mechanisms in simple RNNs, which would enable them to learn various context-free and context-sensitive languages, but none of the RNN architectures proposed in the early days were able to generalize the training set to longer (or more complex) test samples with substantially high accuracy.\nBIBREF9 , on the other hand, proposed a variant of Long Short-Term Memory (LSTM) networks to learn two context-free languages, $a^n b^n$ , $a^n b^m B^m A^n$ , and one strictly context-sensitive language, $a^n b^n c^n$ . Given only a small fraction of samples in a formal language, with values of $n$ (and $m$ ) ranging from 1 to a certain training threshold $N$ , they trained an LSTM model until its full convergence on the training set and then tested it on a more generalized set. They showed that their LSTM model outperformed the previous approaches in capturing and generalizing the aforementioned formal languages.

The authors of the experiment concluded that manual topic labels include a considerable number of phrases; users prefer shorter labels with more general words and tend to incorporate phrases and more generic terminology when using more complex network graph. Blei and Lafferty BIBREF3 visualize topics with ngrams consisting of words mentioned in these topics.

        "evidence": "With the massive increase in social interactions on online social networks, there has also been an increase of hateful activities that exploit such infrastructure. On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs). As baselines, we compare with feature spaces comprising of char n-grams BIBREF0 , TF-IDF vectors, and Bag of Words vectors (BoWV).\nMain contributions of our paper are as follows: (1) We investigate the application of deep learning methods for the task of hate speech detection. (2) We explore various tweet semantic embeddings like char n-grams, word Term Frequency-Inverse Document Frequency (TF-IDF) values, Bag of Words Vectors (BoWV) over Global Vectors for Word Representation (GloVe), and task-specific embeddings learned using FastText, CNNs and LSTMs. (3) Our methods beat state-of-the-art methods by a large margin ( INLINEFORM0 18 F1 points better).\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs).

As someone who grew up in the 1980's, I could identify with the clothing and hair styles, the decor, and the dearth of real-time communication options (no internet, no email, no mobile phones, etc.). The limited communication modes is what led to secret information drop locations in this era, which were a common insurance in the show. But more importantly, I remember the feeling of growing up in the time of the Cold War. We were still having scheduled air raid drills in my grammar school as often as we'd have fire drills! As children, we were convinced that nuclear war was going to happen someday, even if the adults tried to tell us that it wasn't. Growing up about 25 miles from New York City, I was pretty sure that I'd be gone within seconds of a nuclear strike to the city. My next favorite has been Yellowstone. This is a show that seems to appeal to almost everyone because it has plenty of beautiful Western scenes (Montana), family drama, and battles between flawed characters.  This series is still ongoing and I can't wait for the next set of episodes to be released! I'd have to say my third favorite is Billions. It's a series from several years ago that we just happened upon. We are in season 2 of 5 or 6 total seasons, and I am riveted by the characters, especially Bobby Axelrod (Ax), and Chuck and Wendy Rhoades. They are all so intense and engrossed in what they do, so it makes for very interesting interactions and plot twists! And I have to give an Honorable Mention to Perry Mason. While this is a very new series, I absolutely love this period drama so far. The creators have based many of the episodes on similar actual events from this period (the 1930s). It is very difficult to watch Della Street, who is insanely smart and charming, be relegated to the 'brains behind the guy' (Perry Mason) because it's the 1930s. Thanks for reading!

Parts B and C focus on the proposed methods where part B contains methods using neural networks only, while part C uses average of word embeddings learned by DNNs as features for GBDTs. We experimented with multiple classifiers but report results mostly for GBDTs only, due to lack of space.\nAs the table shows, our proposed methods in part B are significantly better than the baseline methods in part A. Among the baseline methods, the word TF-IDF method is better than the character n-gram method. Among part B methods, CNN performed better than LSTM which was better than FastText. Surprisingly, initialization with random embeddings is slightly better than initialization with GloVe embeddings when used along with GBDT. Finally, part C methods are better than part B methods. The best method is “LSTM + Random Embedding + GBDT” where tweet embeddings were initialized to random vectors, LSTM was trained using back-propagation, and then learned embeddings were used to train a GBDT classifier. Combinations of CNN, LSTM, FastText embeddings as features for GBDTs did not lead to better results. Also note that the standard deviation for all these methods varies from 0.01 to 0.025.\nTo verify the task-specific nature of the embeddings, we show top few similar words for a few chosen words in Table TABREF7 using the original GloVe embeddings and also embeddings learned using DNNs. The similar words obtained using deep neural network learned embeddings clearly show the “hatred” towards the target words, which is in general not visible at all in similar words obtained using GloVe.\nWe experimented with multiple classifiers but report results mostly for GBDTs only,due to lack of space.As the table shows, our proposed methods in part B are significantly better than the baseline methods in part A.

When a psychoactive drug enters the user's body, it induces an intoxicating effect. Generally, recreational drugs are divided into three categories: depressants (drugs that induce a feeling of relaxation and calmness), stimulants (drugs that induce a sense of energy and alertness), and hallucinogens (drugs that induce perceptual distortions such as hallucination).\n\nIn popular practice, recreational drug use generally is a tolerated social behaviour, rather than perceived as the medical condition of self-medication. However, drug use and drug addiction are severely stigmatized everywhere in the world. Many people also use prescribed and controlled depressants such as opioids, as well as opiates and benzodiazepines. What controlled substances are considered generally unlawful to possess varies by country, but usually includes cannabis, cocaine, opioids, MDMA, amphetamine, methamphetamine, psychedelics, benzodiazepines, and barbiturates. As of 2015, it is estimated that about 5% of people worldwide aged 15 to 65 (158 million to 351 million) had used controlled drugs at least once.\n\nCommon recreational drugs include caffeine, commonly found in coffee, tea, soft drinks, and chocolate; alcohol, commonly found in beer, wine, cocktails, and distilled spirits; nicotine, commonly found in tobacco, tobacco-based products, and electronic cigarettes; cannabis and hashish (with legality of possession varying inter/intra-nationally); and the controlled substances listed as controlled drugs in the Single Convention on Narcotic Drugs (1961) and the Convention on Psychotropic Substances (1971) of the United Nations (UN). Since the early 2000s, the European Union (EU) has developed several comprehensive and multidisciplinary strategies as part of its drug policy in order to prevent the diffusion of recreational drug use and abuse among the European population and raise public awareness on the adverse effects of drugs among all member states of the European Union, as well as conjoined efforts with European law enforcement agencies, such as the Europol and EMCDDA, in order to counter organized crime and illegal drug trade in Europe.",

The EU has implemented various policies aimed at reducing recreational drug use and addressing issues related to drug trafficking within its borders.\n\nPeople often take recreational drugs because they want to experience feelings of euphoria, increased energy levels, or enhanced sensory perception. However, these drugs can have serious side effects, including dependence, withdrawal symptoms, impaired judgment and motor skills, and even death. Additionally, recreational drug use can lead to legal consequences, financial problems, strained relationships, and health issues such as mental illness, organ damage, and overdose.

The most widely used metric in summarization evaluation has been the ROUGE family. ROUGE solely relies on lexical overlaps between the terms and phrases in the sentences; therefore, in cases of terminology variations and paraphrasing, ROUGE is not as effective. Scientific article summarization is one such case that is different from general domain summarization (e.g. newswire data). We provide an extensive analysis of ROUGE's effectiveness as an evaluation metric for scientific summarization; we show that, contrary to the common belief, ROUGE is not much reliable in evaluating scientific summaries. We furthermore show how different variants of ROUGE result in very different correlations with the manual Pyramid scores. Finally, we propose an alternative metric for summarization evaluation which is based on the content relevance between a system generated summary and the corresponding human written summaries. We call our metric SERA (Summarization Evaluation by Relevance Analysis).

        "answer": "They perform normalisation to prevent the imbalance problem.",
        "evidence": "In Turkish, there do not exist well-established sentiment lexicons as in English. In this approach, we made use of the TDK (Türk Dil Kurumu - “Turkish Language Institution”) dictionary to obtain word polarities. Although it is not a sentiment lexicon, combining it with domain-specific polarity scores obtained from the corpus led us to have state-of-the-art results.\nWe first construct a matrix whose row entries are corpus words and column entries are the words in their dictionary definitions. We followed the boolean approach. For instance, for the word cat, the column words occurring in its dictionary definition are given a score of 1. Those column words not appearing in the definition of cat are assigned a score of 0 for that corresponding row entry.\nWhen we performed clustering on this matrix, we observed that those words having similar meanings are, in general, assigned to the same clusters. However, this similarity fails in capturing the sentimental characteristics. For instance, the words happy and unhappy are assigned to the same cluster, since they have the same words, such as feeling, in their dictionary definitions. However, they are of opposite polarities and should be discerned from each other.\nTherefore, we utilise a metric to move such words away from each other in the VSM, even though they have common words in their dictionary definitions. We multiply each value in a row with the corresponding row word's raw supervised score, thereby having more meaningful clusters. Using the training data only, the supervised polarity score per word is calculated as in (DISPLAY_FORM4).\nHere, $ w_{t}$ denotes the sentiment score of word $t$, $N_{t}$ is the number of documents (reviews or tweets) in which $t$ occurs in the dataset of positive polarity, $N$ is the number of all the words in the corpus of positive polarity. $N^{\\prime }$ denotes the corpus of negative polarity. $N^{\\prime }_{t}$ and $N^{\\prime }$ denote similar values for the negative polarity corpus. We perform normalisation to prevent the imbalance problem and add a small number to both numerator and denominator for smoothing.\nAs an alternative to multiplying with the supervised polarity scores, we also separately multiplied all the row scores with only +1 if the row word is a positive word, and with -1 if it is a negative word. We have observed it boosts the performance more compared to using raw scores.\nThe effect of this multiplication is exemplified in Figure FIGREF7, showing the positions of word vectors in the VSM. Those “x\" words are sentimentally negative words, those “o\" words are sentimentally positive ones. On the top coordinate plane, the words of opposite polarities are found to be close to each other, since they have common words in their dictionary definitions. Only the information concerned with the dictionary definitions are used there, discarding the polarity scores. However, when we utilise the supervised score (+1 or -1), words of opposite polarities (e.g. “happy\" and “unhappy\") get far away from each other as they are translated across coordinate regions. Positive words now appear in quadrant 1, whereas negative words appear in quadrant 3. Thus, in the VSM, words that are sentimentally similar to each other could be clustered more accurately. Besides clustering, we also employed the SVD method to perform dimensionality reduction on the unsupervised dictionary algorithm and used the newly generated matrix by combining it with other subapproaches. The number of dimensions is chosen as 200 again according to the $U$ matrix. The details are given in Section 3.4. When using and evaluating this subapproach on the English corpora, we used the SentiWordNet lexicon BIBREF13. We have achieved better results for the dictionary-based algorithm when we employed the SVD reduction method compared to the use of clustering.\nWe perform normalisation to prevent the imbalance problem and add a small number to both numerator and denominator for smoothing.",

        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nFirst, we use a long short-term memory (LSTM) encoder to embed the question.",

        "answer": "Because there are few suitable datasets available.",
        "evidence": "Datasets. We perform our experiments with two predetermined event categories: cyber security (CyberAttack) and death of politicians (PoliticianDeath). These event categories are chosen as they are representative of important event types that are of interest to many governments and companies. The need to create our own dataset was motivated by the lack of public datasets for event detection on microposts. The few available datasets do not suit our requirements. For example, the publicly available Events-2012 Twitter dataset BIBREF20 contains generic event descriptions such as Politics, Sports, Culture etc. Our work targets more specific event categories BIBREF21. Following previous studies BIBREF1, we collect event-related microposts from Twitter using 11 and 8 seed events (see Section SECREF2) for CyberAttack and PoliticianDeath, respectively. Unlabeled microposts are collected by using the keyword `hack' for CyberAttack, while for PoliticianDeath, we use a set of keywords related to `politician' and `death' (such as `bureaucrat', `dead' etc.) For each dataset, we randomly select 500 tweets from the unlabeled subset and manually label them for evaluation. Table TABREF25 shows key statistics from our two datasets.\nComparison Methods. To demonstrate the generality of our approach on different event detection models, we consider Logistic Regression (LR) BIBREF1 and Multilayer Perceptron (MLP) BIBREF2 as the target models. As the goal of our experiments is to demonstrate the effectiveness of our approach as a new model training technique, we use these widely used models. Also, we note that in our case other neural network models with more complex network architectures for event detection, such as the bi-directional LSTM BIBREF17, turn out to be less effective than a simple feedforward network. For both LR and MLP, we evaluate our proposed human-AI loop approach for keyword discovery and expectation estimation by comparing against the weakly supervised learning method proposed by BIBREF1 (BIBREF1) and BIBREF17 (BIBREF17) where only one initial keyword is used with an expectation estimated by an individual expert.\nParameter Settings. We empirically set optimal parameters based on a held-out validation set that contains 20% of the test data. These include the hyperparamters of the target model, those of our proposed probabilistic model, and the parameters used for training the target model. We explore MLP with 1, 2 and 3 hidden layers and apply a grid search in 32, 64, 128, 256, 512 for the dimension of the embeddings and that of the hidden layers. For the coefficient of expectation regularization, we follow BIBREF6 (BIBREF6) and set it to $\\lambda =10 \\times $ #labeled examples. For model training, we use the Adam BIBREF22 optimization algorithm for both models.\nEvaluation. Following BIBREF1 (BIBREF1) and BIBREF3 (BIBREF3), we use accuracy and area under the precision-recall curve (AUC) metrics to measure the performance of our proposed approach. We note that due to the imbalance in our datasets (20% positive microposts in CyberAttack and 27% in PoliticianDeath), accuracy is dominated by negative examples; AUC, in comparison, better characterizes the discriminative power of the model.\nCrowdsourcing. We chose Level 3 workers on the Figure-Eight crowdsourcing platform for our experiments. The inter-annotator agreement in micropost classification is taken into account through the EM algorithm. For keyword discovery, we filter keywords based on the frequency of the keyword being selected by the crowd. In terms of cost-effectiveness, our approach is motivated from the fact that crowdsourced data annotation can be expensive, and is thus designed with minimal crowd involvement. For each iteration, we selected 50 tweets for keyword discovery and 50 tweets for micropost classification per keyword. For a dataset with 80k tweets (e.g., CyberAttack), our approach only requires to manually inspect 800 tweets (for 8 keywords), which is only 1% of the entire dataset.\nThe need to create our own dataset was motivated by the lack of public datasets for event detection on microposts.The few available datasets do not suit our requirements.",

        "answer": "The impact of discourse representations obtained from an Rhetorical Structure Theory (RST) parser on natural language generation and document classification.",
        "evidence": "Natural language generation and document classification have been widely conducted using neural sequence models based on the encoder–decoder architecture. The underlying technique relies on the production of a context vector as the document representation, to estimate both tokens in natural language generation and labels in classification tasks. By combining recurrent neural networks with attention BIBREF0, the model is able to learn contextualized representations of words at the sentence level. However, higher-level concepts, such as discourse structure beyond the sentence, are hard for an RNN to learn, especially for longer documents. We hypothesize that NLP tasks such as summarization and document classification can be improved through the incorporation of discourse information.\nIn this paper, we propose to incorporate latent representations of discourse units into neural training. A discourse parser can provide information about the document structure as well as the relationships between discourse units. In a summarization scenario, for example, this information may help to remove redundant information or discourse disfluencies. In the case of document classification, the structure of the text can provide valuable hints about the document category. For instance, a scientific paper follows a particular discourse narrative pattern, different from a short story. Similarly, we may be able to predict the societal influence of a document such as a petition document, in part, from its discourse structure and coherence.\nSpecifically, discourse analysis aims to identify the organization of a text by segmenting sentences into units with relations. One popular representation is Rhetorical Structure Theory (RST) proposed by mann1988rhet, where the document is parsed into a hierarchical tree, where leaf nodes are the segmented units, known as Entity Discourse Units (EDUs), and non-terminal nodes define the relations.\nAs an example, in Figure FIGREF1 the two-sentence text has been annotated with discourse structure based on RST, in the form of 4 EDUs connected with discourse labels attr and elab. Arrows in the tree capture the nuclearity of relations, wherein a “satellite” points to its “nucleus”. The Nucleus unit is considered more prominent than the Satellite, indicating that the Satellite is a supporting sentence for the Nucleus. Nuclearity relationships between two EDUs can take the following three forms: Nucleus–Satellite, Satellite–Nucleus, and Nucleus–Nucleus. In this work, we use our reimplementation of the state of the art neural RST parser of BIBREF1, which is based on eighteen relations: purp, cont, attr, evid, comp, list, back, same, topic, mann, summ, cond, temp, eval, text, cause, prob, elab.\nThis research investigates the impact of discourse representations obtained from an RST parser on natural language generation and document classification. We primarily experiment with an abstractive summarization model in the form of a pointer–generator network BIBREF2, focusing on two factors: (1) whether summarization benefits from discourse parsing; and (2) how a pointer–generator network guides the summarization model when discourse information is provided. For document classification, we investigate the content-based popularity prediction of online petitions with a deep regression model BIBREF3. We argue that document structure is a key predictor of the societal influence (as measured by signatures to the petition) of a document such as a petition.\nOur primary contributions are as follows: (1) we are the first to incorporate a neural discourse parser in sequence training; (2) we empirically demonstrate that a latent representation of discourse structure enhances the summaries generated by an abstractive summarizer; and (3) we show that discourse structure is an essential factor in modelling the popularity of online petitions.\nThis research investigates the impact of discourse representations obtained from an RST parser on natural language generation and document classification.",

Licence details: http://creativecommons.org/licenses/by/4.0/\nRecent years have seen a surge of interest in automatic keyphrase extraction, thanks to the availability of the SemEval-2010 benchmark dataset BIBREF0 . This dataset is composed of documents (scientific articles) that were automatically converted from PDF format to plain text. As a result, most documents contain irrelevant pieces of text (e.g. muddled sentences, tables, equations, footnotes) that require special handling, so as to not hinder the performance of keyphrase extraction systems. In previous work, these are usually removed at the preprocessing step, but using a variety of techniques ranging from simple heuristics BIBREF1 , BIBREF2 , BIBREF3 to sophisticated document logical structure detection on richly-formatted documents recovered from Google Scholar BIBREF4 . Under such conditions, it may prove difficult to draw firm conclusions about which keyphrase extraction model performs best, as the impact of preprocessing on overall performance cannot be properly quantified.\nWhile previous work clearly states that efficient document preprocessing is a prerequisite for the extraction of high quality keyphrases, there is, to our best knowledge, no empirical evidence of how preprocessing affects keyphrase extraction performance.

        "question": "What do they use to pre-train the encoder-decoder attention mechanism?",
        "answer": "The denoising auto-encoding (DAE) objective.",
        "evidence": "The masked language modeling (MLM) BIBREF13 task, also known as the Cloze task BIBREF23, aims at predicting the randomly masked words according to their context. The objective pretrains the bidirectional encoder to obtain contextual representations. Following BIBREF13, we randomly mask 15% of the tokens in a monolingual sentence. For each masked token, we substitute it with a special token M, a random token, or the unchanged token with a probability of 0.8, 0.1, and 0.1, respectively. Let $x$ denote a sentence from the monolingual training corpus, and $M_{x}$ the set of randomly masked positions. The monolingual MLM loss is defined as: MLM(x) = -i Mxp( xi | xMx) where $x_{\\setminus M_{x}}$ is the masked version of input $x$. Notice that language tags are fed into the model for all pre-training tasks.\nWe use the denoising auto-encoding (DAE) objective BIBREF24 to pretrain the encoder-decoder attention mechanism. Given sentence $x$ from the monolingual corpus, we use three types of noise to obtain the randomly perturbed text $\\hat{x}$. First, the word order is locally shuffled. Second, we randomly drop tokens of the sentence with a probability of $0.1$. Third, we substitute tokens with the special padding token P with a probability of $0.1$. The pre-training objective is to recover the original sentence $x$ by conditioning on $\\hat{x}$. The DAE loss is computed via: DAE(x) = -p(x|x) = -i = 1|x|p(xi | x, x<i) where $x_{<i}$ represents the tokens of previous time steps $x_1,\\cdots ,x_{i-1}$.\nSimilar to monolingual MLM, the masked token prediction task can be extended to cross-lingual settings BIBREF5. To be specific, given a parallel corpus, we concatenate the pair of bilingual sentences $(x,y)$ to a whole sequence, and use it as the input of MLM. The language tags are also fed into the model to indicate the languages of tokens. During training, we adopt the same masking strategy as monolingual MLM. Apart from using monolingual context to predict the masked tokens, XMLM encourages the model to utilize the alignment of bilingual sentences, so that the model learns to map cross-lingual texts into a shared vector space. Similar to eq:mlm, the cross-lingual MLM loss is: XMLM(x,y) = -i Mxp( xi | xMx , yMy)\n-i Myp( yi | xMx , yMy) where $M_x, M_y$ represent the masked positions of $x$ and $y$, respectively.\nIf only DAE is used as the pre-training task for the decoder, we found that the model ignores the target language tag while generating just the same language as the input, caused by the spurious correlation issue BIBREF25. In other words, the DAE loss captures the spurious correlation between the source language tag and the target sentences, but we expect the language of generated sentences can be controlled by the target language tag. To solve the above problem, we use machine translation as the cross-lingual auto-encoding (XAE) task, which decreases mutual information between the target sentences and the source language tag. XAE can be viewed as the multilingual-version DAE task in the sense that both of them recover the sentence by conditioning on the encoded representations. The cross-lingual auto-encoding loss is defined as: XAE(x,y) = -p(y|x) - p(x|y) where $(x,y)$ is a pair of sentences in the parallel corpus.\nDenoising Auto-Encoding (DAE) We use the denoising auto-encoding (DAE) objective (Vincent et al. 2008) to pretrain the encoder-decoder attention mechanism.",

        "evidence": "To study model sensitivity, for each sentence, we perturb one randomly-chosen word and replace it with all possible perturbations under a given attack type. The resulting set of perturbed sentences is then fed to the word recognizer (whose sensitivity is to be estimated). As described in equation 12 , we count the number of unique predictions from the output sentences. Two corrections are considered unique if they are mapped differently by the downstream classifier.\nThe neutral backoff variant has the lowest sensitivity (Table 5 ). This is expected, as it returns a fixed neutral word whenever the ScRNN predicts an UNK, therefore reducing the number of unique outputs it predicts. Open vocabulary (i.e. char-only, word+char, word-piece) downstream classifiers consider every unique combination of characters differently, whereas word-only classifiers internally treat all out of vocabulary (OOV) words alike. Hence, for char-only, word+char, and word-piece models, the pass-through version is more sensitive than the background variant, as it passes words as is (and each combination is considered uniquely). However, for word-only models, pass-through is less sensitive as all the OOV character combinations are rendered identical.\nIdeally, a preferred defense is one with low sensitivity and word error rate. In practice, however, we see that a low error rate often comes at the cost of sensitivity. We see this trade-off in Figure 2 , where we plot WER and sensitivity on the two axes, and depict the robustness when using different backoff variants. Generally, sensitivity is the more dominant factor out of the two, as the error rates of the considered variants are reasonably low.\nWe verify if the sentiment (of the reviews) is preserved with char-level attacks. In a human study with 50 attacked (and subsequently misclassified), and 50 unchanged reviews, it was noted that 48 and 49, respectively, preserved the sentiment.\nTo study model sensitivity, for each sentence, we perturb one randomlychosen word and replace it with all possible perturbations under a given attack type.

        "question": "What is the best modern motorcycle for a beginning rider?",
        "evidence": "",
        "answer": "If you have no or little experience with motorcycles, choosing a good first motorcycle can be challenging. While it is tempting to buy your dream supersport or touring cruiser, your first bike should be one that you can feel confident on so you can quickly master the skills necessary to ride a faster or larger bike more safely. Assess a new bike not from a place of desire, but from practical perspective, and consider these qualities:\n\n- Seat height: For most new riders, confidence comes more quickly when you can place both feet on the ground with a little bend in the knees. If you have a 32\" inseam, consider bikes with a 31\" or less seat height. If you have a 28\" inseam, consider bikes with a 27\" or lower seat height. Note that some bikes have wider \"waists\" that require you to spread your legs farther apart, so visit a dealer and sit on a variety of bikes until you find ones that you can sit comfortable atop with both feet planted.\n\n- Center of gravity: Bikes weigh from 250 lbs (dirt bikes) to over 800 lbs (large \"dresser\" cruiser bikes). Most bikes weigh between 400 and 600 lbs. However, weight isn't what makes a bike tip over easily -- rather, it's where the center of gravity is located. Sport bikes and adventure bikes carry their weight higher and more forward in the frame, where as standard and cruiser bikes carry it lower and closer to the rider. If you, as a new rider, grab a fistful of front brake during a low speed maneuver, what is going to cause the bike to start tipping over faster? Having a heavy weight high and forward. When assessing a first bike, look at where the engine and transmission mass seems to be centered relative to rider position. Sit on the bike with both feet planted and tilt it a little to the left and the right. Do you feel more or less strain on your shoulders as you bring it back it back to center? If you feel more, that sensation will become a danger when your learning low speed maneuvers and require more physical compensation, and will inhibit your ability to develop a good low speed riding technique.\n\n- Ergonomics: Most people feel cool in a racer's lean on a supersport, or slung back in a feet-forward posture when riding a cruiser. However, starting in those positions as a new rider can lead to discomfort, or inhibit your ability to develop solid basic riding techniques. Ideally, you want to be upright, elbows loose and bent and even with the bars. Your back should be straight with about a 5 degree forward lean. Your feet should be below your hips with a comfortable bend to the knees. In this position, you have the flexibility to better compensate for a lack of experience and technique when you encounter challenging situations on the road.\n\n- Engine displacement: Much ado is made about choosing the right displacement for a start bike. This is a bit of a myth: very few bikes, regardless of displacement, are fundamentally hostile to a new rider when it comes to engine performance: they are as fast or as slow as you treat the throttle. That said, smaller displacement bikes tend to be lighter, have lower seats, and are generally more newbie-friendly. However, some larger displacement bikes, including 650-900cc standards and 1100cc-plus cruisers can also be safe to learn on, as they favor low-revving torque over high-revving horsepower, with relatively gentle throttle response but plenty of grunt to push you forward from idle without extensive clutch feathering and rev management. Conversely, some smaller bikes, like the Kawasaki Ninja 250, require extensive revving and frequent gear shifting to get to street and highway speeds. Ask yourself: Do I want a light bike that will force me to learn good gear and rev management (a good idea if you have track aspirations), or a heavier bike that starts moving right off idle and requires less gear changing at street speeds? That's your answer to the question of displacement.\n\n- Throttle and brake response. Modern fuel injection, ECU development, and environmental emissions regulations have led to a situation where many sportier bikes have notchy throttles at low speeds, where closing the throttle cuts fuel and causes the bike to lurch a bit. This can be unpleasant for new riders who have yet to learn partial clutch management skills. Additionally, powerful sport bikes with inline-4 or V4 engine configuration can stutter and lurch at very low revs, requiring careful clutch and rev management that might be unfamiliar or uncomfortable to new riders -- these are bikes designed to be ridden fast, high in their powerbands. Additionally, powerful supersports and \"hooligan\" supermotos have very powerful brakes, like Brembo's Stylema or M4 units, which can easily pitch a new rider over the bars if they haven't developed a light, progressive touch on the brakes. If you, as a new rider, are having to spend your riding time compensating for unpredictable throttle behaviors or aggressive brakes, you aren't in a place to quickly learn good techniques safely.\n\nSo with all that in mind, what are some good starter bikes?\n\n- Kawasaki Ninja 400 or Z400: If your ambition is to ride a powerful supersport (like Kawasaki's own ZX-10R), start with a Ninja 400 or Z400. The Ninja is similar in style to supersport bikes, but has raised \"clip-on\" handle bars that convey the appearance of a racer but raise the incline of your posture to a more comfortable space. They also have a slightly lower seat height, and an accommodating 399cc parallel-twin motor with good throttle response and solid but unthreatening brakes. The Z400 is a more upright version of the Ninja 400 that shares the same engine and brakes, but lacks the plastic fairing and clip-on grips. Similar bikes include Yamaha's 321cc R3 and MT-03, Honda's CBR500F and CBR500R, KTM's RC390 and Duke 390, and BMW's G310. All of them perform very similarly, and are considered great gateway bikes to sport riding. Many track enthusiasts favor these bikes due to their light weight, engaging engines, and overall low cost of maintenance and insurance. If you really feel the need for speed so early in your riding career, Yamaha's MT-07 and Triumph's Trident 660 are relatively safe choices.\n\n- Triumph Street Twin 900. While well over 400 lbs, Triumph's Street Twin 900 is a very newbie friendly bike with a smooth, slow revving 900cc parallel-twin engine that puts down a lot of grunt and requires very little rev management -- you can short shift it any gear and still have the torque to move away cleanly without any fuss. Its comfortable seat and neutral \"standard\" riding position, along with its traction control and ABS features, mean that riding it is effortless and you won't be sore when you step off it after a long day cruising the backroads. It carries its weight low and close to the rider, and has a low-ish seat height of approximately 30\". Brakes are progressive without being intimidating, and a new rider will quickly learn good technique astride it. It also looks the part of a modern retro motorcycle, with clean curb appeal. Similar bikes include Moto Guzzi's V7 series, Kawasaki's Z650RS, and Royal Enfield's 650cc Interceptor.\n\n- Honda's Rebel 500. While it may not be the most eye-catching cruiser at the local Starbucks, Honda's Rebel 500 is a great gateway to the cruiser world. The 500cc engine is tuned for torque, not speed, and its low seat height of around 26\" means it is approachable by riders of all heights. It can keep up with larger bikes and serves as an effective commuter, with low costs of insurance and maintenance, and can be easily customized. Similar bikes include Royal Enfield's 350 Meteor and 650 Super Meteor, and Honda's 600cc Shadow line. For those not intimidated by weight, Harley-Davidson's 1700cc Heritage Softail is a surprisingly accommodating bike for new riders, with a low seat height and an impressive center of gravity that makes the bike feel a couple hundred pounds lighter once bumped off its kickstand. Avoid the older Sportster line, often inappropriately pitched as \"the Harley for new riders\" due to their relatively low displacements compared to KD's more upmarket models -- these bikes have very high-and-forward centers of gravity and weak front brakes that can easily inhibit your skills development.\n\nLastly, if you're looking at adventure bikes, Royal Enfield's 400cc Himalayan, Kawasaki's Versys 300X, and BMW's G310GS provide light weights, friendly engines, and reasonable seat heights all while being moderately well-equipped for gravel or graded dirt roads.\n\nThe most important thing, however, is to take the time to sit on the bikes at a dealer and think hard about the qualities discussed in this article. If you fall in love with the hobby, the bike you get today will not be the bike you have tomorrow. Focus on learning, not fashion, and make a choice that feels comfortable and safe to you.",

        "question": "What model and classifier are used to classify utterances from PD patients and healthy control subjects?",
        "answer": "A Gaussian mixture model (GMMs) and SVMs.",
        "evidence": "Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the mid-brain producing several motor and non-motor impairments in the patients BIBREF0. Motor symptoms include among others, bradykinesia, rigidity, resting tremor, micrographia, and different speech impairments. The speech impairments observed in PD patients are typically grouped as hypokinetic dysarthria, and include symptoms such as vocal folds rigidity, bradykinesia, and reduced control of muscles and limbs involved in the speech production. The effects of dysarthria in the speech of PD patients include increased acoustic noise, reduced intensity, harsh and breathy voice quality, increased voice nasality, monopitch, monoludness, speech rate disturbances, imprecise articulation of consonants BIBREF1, and involuntary introduction of pauses BIBREF2. Clinical observations in the speech of patients can be objectively and automatically measured by using computer aided methods supported in signal processing and pattern recognition with the aim to address two main aspects: (1) to support the diagnosis of the disease by classifying healthy control (HC) subjects and patients, and (2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.\nMost of the studies in the literature to classify PD from speech are based on computing hand-crafted features and using classifiers such as support vector machines (SVMs) or K-nearest neighbors (KNN). For instance, in BIBREF3, the authors computed features related to perturbations of the fundamental frequency and amplitude of the speech signal to classify utterances from 20 PD patients and 20 HC subjects, Turkish speakers. Classifiers based on KNN and SVMs were considered, and accuracies of up to 75% were reported. Later, in BIBREF4 the authors proposed a phonation analysis based on several time frequency representations to assess tremor in the speech of PD patients. The extracted features were based on energy and entropy computed from time frequency representations. Several classifiers were used, including Gaussian mixture models (GMMs) and SVMs. Accuracies of up to 77% were reported in utterances of the PC-GITA database BIBREF5, formed with utterances from 50 PD patients and 50 HC subjects, Colombian Spanish native speakers. The authors from BIBREF6 computed features to model different articulation deficits in PD such as vowel quality, coordination of laryngeal and supra-laryngeal activity, precision of consonant articulation, tongue movement, occlusion weakening, and speech timing. The authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier. Additional articulation features were proposed in BIBREF7, where the authors modeled the difficulty of PD patients to start/stop the vocal fold vibration in continuous speech. The model was based on the energy content in the transitions between unvoiced and voiced segments. The authors classified PD patients and HC speakers with speech recordings in three different languages (Spanish, German, and Czech), and reported accuracies ranging from 80% to 94% depending on the language; however, the results were optimistic, since the hyper-parameters of the classifier were optimized based on the accuracy on the test set. Another articulation model was proposed in BIBREF8. The authors considered a forced alignment strategy to segment the different phonetic units in the speech utterances. The phonemes were segmented and grouped to train different GMMs. The classification was performed based on a threshold of the difference between the posterior probabilities from the models created for HC subjects and PD patients. The model was tested with Colombian Spanish utterances from the PC-GITA database BIBREF5 and with the Czech data from BIBREF9. The authors reported accuracies of up to 81% for the Spanish data, and of up to 94% for the Czech data.\nIn addition to the hand-crafted feature extraction models, there is a growing interest in the research community to consider deep learning models in the assessment of the speech of PD patients BIBREF10, BIBREF11, BIBREF12. Deep learning methods have the potential to extract more abstract and robust features than those manually computed. These features could help to improve the accuracy of different models to classify pathological speech, such as PD BIBREF13. A deep learning based articulation model was proposed in BIBREF11 to model the difficulties of the patients to stop/start the vibration of the vocal folds. Transitions between voiced and unvoiced segments were modeled with time-frequency representations and convolutional neural networks (CNNs). The authors considered speech recordings of PD patients and HC speakers in three languages: Spanish, German, and Czech, and reported accuracies ranging from 70% to 89%, depending on the language. However, in a language independent scenario, i.e., training the CNN with utterances from one language and testing with the remaining two, the results were not satisfactory (accuracy$<60\\%$).\nThe classification of PD from speech in different languages has to be carefully conducted to avoid bias towards the linguistic content present in each language. For instance, Czech and German languages are richer than Spanish language in terms of consonant production, which may cause that it is easier to produce consonant sounds by Czech PD patients than by Spanish PD patients. Despite these language dependent issues, the results in the classification of PD in different languages could be improved using a transfer learning strategy among languages, i.e., to train a base model with utterances from one language, and then, to perform a fine-tuning of the weights with utterances from the target language BIBREF14. Similar approaches based on transfer learning have been recently considered to classify PD using handwriting BIBREF15. In the present study, we propose a methodology to classify PD via a transfer learning strategy with the aim to improve the accuracy in different languages. CNNs trained with utterances from one language are used to initialize a model to classify speech utterances from PD patients in a different language. The models are evaluated with speech utterances in Spanish, German, and Czech languages. The results suggest that the use of a transfer learning strategy improved the accuracy of the models over 8% with respect to those obtained when the model is trained only with utterance from the target language.\nThe extracted features were based on energy and entropy computed from time frequency representations. Several classifiers were used, including Gaussian mixture models (GMMs) and SVMs. Accuracies of up to 77% were reported in utterances of the PC-GITA database [6], formed with utterances from 50 PD patients and 50 HC subjects, Colombian Spanish native speakers. The authors from [7] computed features to model different articulation deficits in PD such as vowel quality, coordination of laryngeal and supra-laryngeal activity, precision of consonant articulation, tongue movement, occlusion weakening, and speech timing. The authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier.",

        "answer": "Given that words from texts of the same class belong to the same context, it is possible to model word vectors of each text class as word subspaces and efficiently compare them in terms of similarity by using canonical angles between the word subspaces.",
        "evidence": "Text classification has become an indispensable task due to the rapid growth in the number of texts in digital form available online. It aims to classify different texts, also called documents, into a fixed number of predefined categories, helping to organize data, and making easier for users to find the desired information. Over the past three decades, many methods based on machine learning and statistical models have been applied to perform this task, such as latent semantic analysis (LSA), support vector machines (SVM), and multinomial naive Bayes (MNB).\nThe first step in utilizing such methods to categorize textual data is to convert the texts into a vector representation. One of the most popular text representation models is the bag-of-words model BIBREF0 , which represents each document in a collection as a vector in a vector space. Each dimension of the vectors represents a term (e.g., a word, a sequence of words), and its value encodes a weight, which can be how many times the term occurs in the document.\nDespite showing positive results in tasks such as language modeling and classification BIBREF1 , BIBREF2 , BIBREF3 , the BOW representation has limitations: first, feature vectors are commonly very high-dimensional, resulting in sparse document representations, which are hard to model due to space and time complexity. Second, BOW does not consider the proximity of words and their position in the text and consequently cannot encode the words semantic meanings.\nTo solve these problems, neural networks have been employed to learn vector representations of words BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . In particular, the word2vec representation BIBREF8 has gained attention. Given a training corpus, word2vec can generate a vector for each word in the corpus that encodes its semantic information. These word vectors are distributed in such a way that words from similar contexts are represented by word vectors with high correlation, while words from different contexts are represented by word vectors with low correlation.\nOne crucial aspect of the word2vec representation is that arithmetic and distance calculation between two word vectors can be performed, giving information about their semantic relationship. However, rather than looking at pairs of word vectors, we are interested in studying the relationship between sets of vectors as a whole and, therefore, it is desirable to have a text representation based on a set of these word vectors.\nTo tackle this problem, we introduce the novel concept of word subspace. It is mathematically defined as a low dimensional linear subspace in a word vector space with high dimensionality. Given that words from texts of the same class belong to the same context, it is possible to model word vectors of each class as word subspaces and efficiently compare them in terms of similarity by using canonical angles between the word subspaces. Through this representation, most of the variability of the class is retained. Consequently, a word subspace can effectively and compactly represent the context of the corresponding text. We achieve this framework through the mutual subspace method (MSM) BIBREF9 .\nThe word subspace of each text class is modeled by applying PCA without data centering to the set of word vectors of the class. When modeling the word subspaces, we assume only one occurrence of each word inside the class.\nHowever, as seen in the BOW approach, the frequency of words inside a text is an informative feature that should be considered. In order to introduce this feature in the word subspace modeling and enhance its performance, we further extend the concept of word subspace to the term-frequency (TF) weighted word subspace.\nIn this extension, we consider a set of weights, which encodes the words frequencies, when performing the PCA. Text classification with TF weighted word subspace can also be performed under the framework of MSM. We show the validity of our modeling through experiments on the Reuters database, an established database for natural language processing tasks. We demonstrate the effectiveness of the word subspace formulation and its extension, comparing our methods' performance to various state-of-art methods.\nThe main contributions of our work are:\nThe remainder of this paper is organized as follows. In Section \"Related Work\" , we describe the main works related to text classification. In Section \"Word subspace\" , we present the formulation of our proposed word subspace. In Section \"Conventional text classification methods\" , we explain how text classification with word subspaces is performed under the MSM framework. Then, we present the TF weighted word subspace extension in Section \"TF weighted word subspace\" . Evaluation experiments and their results are described in Section \"Experimental Evaluation\" . Further discussion is then presented in Section \"Discussion\" , and our conclusions are described in Section \"Conclusions and Future Work\" .\nGiven that words from texts of the same class belong to the same context, it is possible to model word vectors of each class as word subspaces and efficiently compare them in terms of similarity by using canonical angles between the word subspaces.",

Successfully understanding, participating or communicating with others in these situations presupposes some form of reasoning: about individual sentences, whole paragraphs of legal documents, small or bigger pieces of dialogue and so on. The human reasoning performed in these different situations cannot be explained by a single rigid system of reasoning, plainly because reasoning is performed in different ways in each one of them. Consider the following example:\nThree representatives are needed.\nIf a human reasoner with expert knowledge was to interpret the above utterance in a legal context, s/he will most probably judge that a situation where more than three references are provided could be compatible with the semantics of the utterance. To the contrary, if the same reasoner was to interpret the above as part of a casual, everyday conversation, then three would most likely be interpreted as exactly three, making the same situation incompatible with the utterance.

        "question": "Based on the reference text, what were the main countries and alliances of World War II?",
        "evidence": "World War II or the Second World War, often abbreviated as WWII or WW2, was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.\n\nWorld War II was by far the deadliest conflict in history; it resulted in an estimated 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massacres, and disease. In the wake of the Axis defeat, Germany and Japan were occupied, and war crimes tribunals were conducted against German and Japanese leaders.\n\nThe causes of World War II are debated, but contributing factors included the Second Italo-Ethiopian War, Spanish Civil War, Second Sino-Japanese War, Soviet–Japanese border conflicts, the rise of fascism in Europe, and European tensions in the aftermath of World War I. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland. The United Kingdom and France subsequently declared war on Germany on 3 September. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union had partitioned Poland and marked out their \"spheres of influence\" across Finland, Estonia, Latvia, Lithuania and Romania. From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, in a military alliance with Italy, Japan and other countries called the Axis. Following the onset of campaigns in North Africa and East Africa, and the fall of France in mid-1940, the war continued primarily between the European Axis powers and the British Empire, with war in the Balkans, the aerial Battle of Britain, the Blitz of the United Kingdom, and the Battle of the Atlantic. On 22 June 1941, Germany led the European Axis powers in an invasion of the Soviet Union, opening the Eastern Front, the largest land theatre of war in history.\n\nJapan, which aimed to dominate Asia and the Pacific, was at war with the Republic of China by 1937. In December 1941, Japan attacked American and British territories with near-simultaneous offensives against Southeast Asia and the Central Pacific, including an attack on the US fleet at Pearl Harbor which resulted in the United States and United Kingdom declaring war against Japan. The European Axis powers declared war on the United States in solidarity. Japan soon captured much of the western Pacific, but its advances were halted in 1942 after losing the critical Battle of Midway; later, Germany and Italy were defeated in North Africa and at Stalingrad in the Soviet Union. Key setbacks in 1943—including a series of German defeats on the Eastern Front, the Allied invasions of Sicily and the Italian mainland, and Allied offensives in the Pacific—cost the Axis powers their initiative and forced them into strategic retreat on all fronts. In 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained its territorial losses and pushed Germany and its allies back. During 1944 and 1945, Japan suffered reversals in mainland Asia, while the Allies crippled the Japanese Navy and captured key western Pacific islands.\n\nThe war in Europe concluded with the liberation of German-occupied territories and the invasion of Germany by the Western Allies and the Soviet Union, culminating in the Fall of Berlin to Soviet troops, Hitler's suicide, and the German unconditional surrender on 8 May 1945. Following the refusal of Japan to surrender on the terms of the Potsdam Declaration (issued 26 July 1945), the United States dropped the first atomic bombs on the Japanese cities of Hiroshima on 6 August and Nagasaki on 9 August. Faced with an imminent invasion of the Japanese archipelago, the possibility of additional atomic bombings, and the Soviet Union's declared entry into the war against Japan on the eve of invading Manchuria, Japan announced on 10 August its intention to surrender, signing a surrender document on 2 September 1945.\n\nWorld War II changed the political alignment and social structure of the globe and set the foundation for the international order of the world's nations during the Cold War and into present day. The United Nations was established to foster international co-operation and prevent future conflicts, with the victorious great powers—China, France, the Soviet Union, the United Kingdom, and the United States—becoming the permanent members of its Security Council. The Soviet Union and the United States emerged as rival superpowers, setting the stage for the nearly half-century-long Cold War. In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia. Most countries whose industries had been damaged moved towards economic recovery and expansion. Political and economic integration, especially in Europe, began as an effort to forestall future hostilities, end pre-war enmities, and forge a sense of common identity.",

        "question": "Are variants of MPAD behaving better than the origin MPAD？",
        "answer": "On 9 datasets out of 10, one or more of the hierarchical variants outperform the vanilla MPAD architecture.",
        "evidence": "Experimental results are shown in Table TABREF28. For the baselines, the best scores reported in each original paper are shown. MPAD reaches best performance on 7 out of 10 datasets, and is close second elsewhere. Moreover, the 7 datasets on which MPAD ranks first widely differ in training set size, number of categories, and prediction task (topic, sentiment, subjectivity), which indicates that MPAD can perform well in different settings.\nMPAD vs. hierarchical variants. On 9 datasets out of 10, one or more of the hierarchical variants outperform the vanilla MPAD architecture, highlighting the benefit of explicitly modeling the hierarchical nature of documents.\nHowever, on Subjectivity, standard MPAD outperforms all hierarchical variants. On TREC, it reaches the same accuracy. We hypothesize that in some cases, using a different graph to separately encode each sentence might be worse than using one single graph to directly encode the document. Indeed, in the single document graph, some words that never appear in the same sentence can be connected through common neighbors, as was explained in subsection SECREF7. So, this way, some notion of cross-sentence context is captured while learning representations of words, bigrams, etc. at each MP iteration. This creates better informed representations, resulting in a better document embedding. With the hierarchical variants, on the other hand, each sentence vector is produced in isolation, without any contextual information about the other sentences in the document. Therefore, the final sentence embeddings might be of lower quality, and as a group might also contain redundant/repeated information. When the sentence vectors are finally combined into a document representation, it is too late to take context into account.\nTo understand the impact of some hyperparameters on performance, we conducted additional experiments on the Reuters, Polarity, and IMDB datasets, with the non-hierarchical version of MPAD. Results are shown in Table TABREF29.\nNumber of MP iterations. First, we varied the number of message passing iterations from 1 to 4. We can clearly see in Table TABREF29 that having more iterations improves performance. We attribute this to the fact that we are reading out at each iteration from 1 to $T$ (see Eq. DISPLAY_FORM18), which enables the final graph representation to encode a mixture of low-level and high-level features. Indeed, in initial experiments involving readout at $t$=$T$ only, setting $T\\ge 2$ was always decreasing performance, despite the GRU-based updates (Eq. DISPLAY_FORM14). These results were consistent with that of BIBREF53 and BIBREF9, who both are reading out only at $t$=$T$ too. We hypothesize that node features at $T\\ge 2$ are too diffuse to be entirely relied upon during readout. More precisely, initially at $t$=0, node representations capture information about words, at $t$=1, about their 1-hop neighborhood (bigrams), at $t$=2, about compositions of bigrams, etc. Thus, pretty quickly, node features become general and diffuse. In such cases, considering also the lower-level, more precise features of the earlier iterations when reading out may be necessary.\nUndirected edges. On Reuters, using an undirected graph leads to better performance, while on Polarity and IMDB, it is the opposite. This can be explained by the fact that Reuters is a topic classification task, for which the presence or absence of some patterns is important, but not necessarily the order in which they appear, while Polarity and IMDB are sentiment analysis tasks. To capture sentiment, modeling word order is crucial, e.g., in detecting negation.\nNo master node. Removing the master node deteriorates performance across all datasets, clearly showing the value of having such a node. We hypothesize that since the special document node is connected to all other nodes, it is able to encode during message passing a summary of the document.\nNo renormalization. Here, we do not use the renormalization trick of BIBREF9 during MP (see subsection SECREF10). That is, Eq. DISPLAY_FORM11 becomes $\\mathbf {M}^{t+1} = \\textsc {MLP}^{t+1}\\big (\\mathbf {A}\\mathbf {H}^{t}\\big )$. In other words, instead of computing a weighted average of the incoming neighbors' feature vectors, we compute a weighted sum of them. Unlike the mean, which captures distributions, the sum captures structural information BIBREF14. As shown in Table TABREF29, using sum instead of mean decreases performance everywhere, suggesting that in our application, capturing the distribution of neighbor representations is more important that capturing their structure. We hypothesize that this is the case because statistical word co-occurrence networks tend to have similar structural properties, regardless of the topic, polarity, sentiment, etc. of the corresponding documents.\nNeighbors-only. In this experiment, we replaced the GRU combine function (see Eq. DISPLAY_FORM14) with the identity function. That is, we simply have $\\mathbf {H}^{t+1}$=$\\mathbf {M}^{t+1}$. Since $\\mathbf {A}$ has zero diagonal, by doing so, we completely ignore the previous feature of the node itself when updating its representation. That is, the update is based entirely on its neighbors. Except on Reuters (almost no change), performance always suffers, stressing the need to take into account the root node during updates, not only its neighborhood.\nMPAD vs. hierarchical variants.

He also wrote in and translated from English and French.\n\nPessoa was a prolific writer, and not only under his own name, for he created approximately seventy-five others, of which three stand out, Alberto Caeiro, Álvaro de Campos, and Ricardo Reis. He did not call them pseudonyms because he felt that this did not capture their true independent intellectual life and instead called them heteronyms. These imaginary figures sometimes held unpopular or extreme views.\n\nPessoa's earliest heteronym, at the age of six, was Chevalier de Pas. Other childhood heteronyms included Dr. Pancrácio and David Merrick, followed by Charles Robert Anon, a young Englishman who became Pessoa's alter ego. In 1905/7, when Pessoa was a student at the University of Lisbon, Alexander Search took the place of Anon. The main reason for this was that, although Search was English, he was born in Lisbon, as was his author. But Search represents a transition heteronym that Pessoa used while searching to adapt to the Portuguese cultural reality. After the republican revolution, in 1910, and consequent patriotic atmosphere, Pessoa created another alter ego, Álvaro de Campos, supposedly a Portuguese naval and mechanical engineer, who was born in Tavira, hometown of Pessoa's ancestors, and graduated in Glasgow. Translator and literary critic Richard Zenith notes that Pessoa eventually established at least seventy-two heteronyms. According to Pessoa himself, there are three main heteronyms: Alberto Caeiro, Álvaro de Campos and Ricardo Reis. Pessoa's heteronyms differ from pen names, because they possess distinct biographies, temperaments, philosophies, appearances, writing styles and even signatures. Thus, heteronyms often disagree on various topics, argue and discuss with each other about literature, aesthetics, philosophy, etc.",

        "evidence": "Affordance-aware navigation is a major challenge in solving complex and long-horizon indoor tasks such as ALFRED with both navigation and object interactions. Specifically, given each object of interest in the scene, the agent is required to not only find and approach it but also end up at a pose (x, y, r, h), that is feasible for subsequent interactions with the object. For instance, to open a fridge, the robot should approach the fridge closely enough (so the door is within reach), look at it (so that the fridge is in the field of view), and leave enough room to open the door. To solve a long-horizon task involving multiple navigation and object interaction subgoals, it is natural to use an explicit semantic map, either 2D or 3D, of the environment (similar to Neural Active SLAM Chaplot et al. (2020a)), together with model-based planning (e.g. as in). This line of work tends to generalize better than models that directly learn mappings from human instructions to navigation & interaction actions (e.g., E.T.). With perfect knowledge of the environment, it is possible to achieve (nearly) perfect performance. In practice, however, the semantic map acquired at inference time is usually far from ideal, primarily due to Incompleteness (missing information due to insufficient exploration of the scene) and Inaccuracy (erroneous object location prediction on the map, especially for small objects).\nTo improve exploration performance, we propose a multimodal module that, at each step, predicts an exploration action a ∈ {MoveAhead, RotateLeft, RotateRight} by taking visual observations & actions in the past, step-by-step language instructions, and the explored area map which indicates where the agent has visited. We show that, compared to existing model-based approaches on ALFRED (e.g., which applies random exploration), our use of lowlevel language instructions leads to more efficient exploration. The proposed exploration module operates at the subgoal level and only predicts exploration actions (in contrast to E.T. which directly predicts actions for the entire task). The extra modality (the explored area) facilitates exploration by providing the agent with explicit spatial information. We illustrate the exploration module in Figure, elaborate its details in Section 4.3, and empirically demonstrate its advantages in Section 5.\nTo improve exploration performance, we propose a multimodal module that, at each step, predicts an exploration action a ∈ {MoveAhead, RotateLeft, RotateRight} by taking visual observations & actions in the past, step-by-step language instructions, and the explored area map which indicates where the agent has visited.",

        "answer": "Over-translation and under-translation.",
        "evidence": "Recently, neural machine translation (NMT) has gained popularity in the field of machine translation. The conventional encoder-decoder NMT proposed by Cho2014 uses two recurrent neural networks (RNN): one is an encoder, which encodes a source sequence into a fixed-length vector, and the other is a decoder, which decodes the vector into a target sequence. A newly proposed attention-based NMT by DzmitryBahdana2014 can predict output words using the weights of each hidden state of the encoder by the attention mechanism, improving the adequacy of translation.\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu2016 argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated. This is due to the fact that NMT can not completely convert the information from the source sentence to the target sentence. Mi2016a and Feng2016 pointed out that NMT lacks the notion of coverage vector in phrase-based statistical machine translation (PBSMT), so unless otherwise specified, there is no way to prevent missing translations.\nAnother problem in NMT is an objective function. NMT is optimized by cross-entropy; therefore, it does not directly maximize the translation accuracy. Shen2016 pointed out that optimization by cross-entropy is not appropriate and proposed a method of optimization based on a translation accuracy score, such as expected BLEU, which led to improvement of translation accuracy. However, BLEU is an evaluation metric based on n-gram precision; therefore, repetition of some words may be present in the translation even though the BLEU score is improved.\nTo address to problem of repeating and missing words in the translation, tu2016neural introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences. In their method, after training the forward translation in a manner similar to the conventional attention-based NMT, they train a back-translation model from the hidden state of the decoder into the source sequence by a new decoder to enforce agreement between source and target sentences.\nIn order to confirm the language independence of the framework, we experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoder-reconstructor. Our experiments show that their method offers significant improvement in BLEU scores and alleviates the problem of repeating and missing words in the translation on English-Japanese translation task, though the difference is not significant on Japanese-English translation task.\nIn addition, we jointly train a model of forward translation and back-translation without pre-training, and then evaluate this model. As a result, the encoder-decoder-reconstructor can not be trained well without pre-training, so it proves that we have to train the forward translation model in a manner similar to the conventional attention-based NMT as pre-training.\nThe main contributions of this paper are as follows:\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu et al. (2016) argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated.",

If you will be working on animation, you may want to budget for a stronger graphics card unit (GPU). Similarly, if you are building a gaming computer, a powerful GPU and a solid state drive (SSD) will improve your gaming performance. Additionally, you will need to check the compatibility of all items that you purchase to ensure that your build will actually support each other. While this may be daunting, it actually allows you to have much creative freedom over your computer needs.

        "evidence": "From Wikipedia, the free encyclopedia\nIn online transaction processing (OLTP), information systems typically facilitate and manage transaction-oriented applications. This is contrasted with online analytical processing.\n\nThe term \"transaction\" can have two different meanings, both of which might apply: in the realm of computers or database transactions it denotes an atomic change of state, whereas in the realm of business or finance, the term typically denotes an exchange of economic entities (as used by, e.g., Transaction Processing Performance Council or commercial transactions.): 50  OLTP may use transactions of the first type to record transactions of the second.\n\nOLTP has also been used to refer to processing in which the system responds immediately to user requests. An automated teller machine (ATM) for a bank is an example of a commercial transaction processing application. Online transaction processing applications have high throughput and are insert- or update-intensive in database management. These applications are used concurrently by hundreds of users. The key goals of OLTP applications are availability, speed, concurrency and recoverability (durability). Reduced paper trails and the faster, more accurate forecast for revenues and expenses are both examples of how OLTP makes things simpler for businesses. However, like many modern online information technology solutions, some systems require offline maintenance, which further affects the cost-benefit analysis of an online transaction processing system.\n\nOLTP is typically contrasted to OLAP (online analytical processing), which is generally characterized by much more complex queries, in a smaller volume, for the purpose of business intelligence or reporting rather than to process transactions. Whereas OLTP systems process all kinds of queries (read, insert, update and delete), OLAP is generally optimized for read only and might not even support other kinds of queries. OLTP also operates differently from batch processing and grid computing.: 15 \n\nIn addition, OLTP is often contrasted to OLEP (online event processing), which is based on distributed event logs to offer strong consistency in large-scale heterogeneous systems. Whereas OLTP is associated with short atomic transactions, OLEP allows for more flexible distribution patterns and higher scalability, but with increased latency and without guaranteed upper bound to the processing time.",

        "question": "To create the corpus, what crowdsourcing scheme is developed by them?",
        "answer": "Lowcontext importance annotation.",
        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ). We make these resources publicly available under a permissive license.\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called lowcontext importance annotation.",

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nIn the first architecture, we use LSTM (Hochreiter and Schmidhuber, 1997) for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM (Tai et al., 2015) to represent the input sentences in the form of a dependency tree.",

It was developed by statistician and sociologist Corrado Gini.\nThe Gini coefficient measures the inequality among values of a frequency distribution, such as levels of income. A Gini coefficient of 0 reflects perfect equality, where all income or wealth values are the same, while a Gini coefficient of 1 (or 100%) reflects maximal inequality among values. For example, if everyone has the same income, the Gini coefficient will be 0. In contrast, a Gini coefficient of 1 indicates that within a group of people, a single individual has all the income or consumption, while all others have none.\nThe Gini coefficient was proposed by Corrado Gini as a measure of inequality of income or wealth.  For OECD countries, in the late 20th century, considering the effect of taxes and transfer payments, the income Gini coefficient ranged between 0.24 and 0.49, with Slovenia being the lowest and Mexico the highest. African countries had the highest pre-tax Gini coefficients in 2008–2009, with South Africa having the world's highest, estimated to be 0.63 to 0.7, although this figure drops to 0.52 after social assistance is taken into account, and drops again to 0.47 after taxation.

        "evidence": "Universal text representations are important for many NLP tasks as modern deep learning models are becoming more and more data-hungry and computationally expensive. On one hand, most research and industry tasks face data sparsity problem due to the high cost of annotation. Universal text representations can mitigate this problem to a certain extent by performing implicit transfer learning among tasks. On the other hand, modern deep learning models with millions of parameters are expensive to train and host, while models using text representation as the building blocks can achieve similar performance with much fewer tunable parameters. The pre-computed text embeddings can also help decrease model latency dramatically at inference time.\nSince the introduction of pre-trained word embeddings such as word2vec BIBREF0 and GloVe BIBREF1, a lot of efforts have been devoted to developing universal sentence embeddings. Initial attempts at learning sentence representation using unsupervised approaches did not yield satisfactory performance. Recent work BIBREF2 has shown that models trained in supervised fashion on datasets like Stanford Natural Language Inference (SNLI) corpus BIBREF3 can consistently outperform unsupervised methods like SkipThought vectors BIBREF4. More recently, Universal Sentence Encoder BIBREF5 equipped with the Transformer BIBREF6 as the encoder, co-trained on a large amount of unsupervised training data and SNLI corpus, has demonstrated surprisingly good performance with minimal amounts of supervised training data for a transfer task.\nBERT BIBREF7, one of the latest models that leverage heavily on language model pre-training, has achieved state-of-the-art performance in many natural language understanding tasks ranging from sequence and sequence pair classification to question answering. The fact that pre-trained BERT can be easily fine-tuned with just one additional output layer to create a state-of-the-art model for a wide range of tasks suggests that BERT representations are potential universal text embeddings.\nPassages that consist of multiple sentences are coherent units of natural languages that convey information at a pragmatic or discourse level. While there are many models for generating and evaluating sentence embeddings, there hasn't been a lot of work on passage level embedding generation and evaluation.\nIn this paper, we conducted an empirical study of layer-wise activations of BERT as general-purpose text embeddings. We want to understand to what extent does the BERT representation capture syntactic and semantic information. The sentence-level embeddings are evaluated on downstream and probing tasks using the SentEval toolkit BIBREF8, while the passage-level encodings are evaluated on four passage-level QA datasets (both factoid and non-factoid) under a learning-to-rank setting. Different methods of combining query embeddings with passage-level answer embeddings are examined.\nThe sentence-level embeddings are evaluated on downstream and probing tasks using the SentEval toolkit (Conneau and Kiela, 2018), while the passage-level encodings are evaluated on four passage-level QA datasets (both factoid and nonfactoid) under a learning-to-rank setting.",

Our second method involves shallow syntactic features obtained automatically on downstream task data. Neither approach leads to a significant gain on any of the four downstream tasks we considered relative to ELMo-only baselines. Further analysis using black-box probes confirms that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo's embeddings.

        "evidence": "Distributed representations - dense real-valued vectors that encode the semantics of linguistic units - are ubiquitous in today's NLP research. For single-words or word-like entities, there are established ways to acquire such representations from naturally occurring (unlabelled) training data based on comparatively task-agnostic objectives (such as predicting adjacent words). These methods are well understood empirically BIBREF0 and theoretically BIBREF1 . The best word representation spaces reflect consistently-observed aspects of human conceptual organisation BIBREF2 , and can be added as features to improve the performance of numerous language processing systems BIBREF3 .\nBy contrast, there is comparatively little consensus on the best ways to learn distributed representations of phrases or sentences. With the advent of deeper language processing techniques, it is relatively common for models to represent phrases or sentences as continuous-valued vectors. Examples include machine translation BIBREF8 , image captioning BIBREF9 and dialogue systems BIBREF10 . While it has been observed informally that the internal sentence representations of such models can reflect semantic intuitions BIBREF11 , it is not known which architectures or objectives yield the `best' or most useful representations. Resolving this question could ultimately have a significant impact on language processing systems. Indeed, it is phrases and sentences, rather than individual words, that encode the human-like general world knowledge (or `common sense') BIBREF12 that is a critical missing part of most current language understanding systems.\nWe address this issue with a systematic comparison of cutting-edge methods for learning distributed representations of sentences. We constrain our comparison to methods that do not require labelled data gathered for the purpose of training models, since such methods are more cost-effective and applicable across languages and domains. We also propose two new phrase or sentence representation learning objectives - Sequential Denoising Autoencoders (SDAEs) and FastSent, a sentence-level log-linear bag-of-words model. We compare all methods on two types of task - supervised and unsupervised evaluations - reflecting different ways in which representations are ultimately to be used. In the former setting, a classifier or regression model is applied to representations and trained with task-specific labelled data, while in the latter, representation spaces are directly queried using cosine distance.\nWe observe notable differences in approaches depending on the nature of the evaluation metric. In particular, deeper or more complex models (which require greater time and resources to train) generally perform best in the supervised setting, whereas shallow log-linear models work best on unsupervised benchmarks. Specifically, SkipThought Vectors BIBREF13 perform best on the majority of supervised evaluations, but SDAEs are the top performer on paraphrase identification. In contrast, on the (unsupervised) SICK sentence relatedness benchmark, FastSent, a simple, log-linear variant of the SkipThought objective, performs better than all other models. Interestingly, the method that exhibits strongest performance across both supervised and unsupervised benchmarks is a bag-of-words model trained to compose word embeddings using dictionary definitions BIBREF14 . Taken together, these findings constitute valuable guidelines for the application of phrasal or sentential representation-learning to language understanding systems.\nIndeed, it is phrases and sentences, rather than individual words, that encode the human-like general world knowledge (or ‘common sense’) (Norman, 1972) that is a critical missing part of most current language understanding systems. We address this issue with a systematic comparison of cutting-edge methods for learning distributed representations of sentences.",

        "question": "What are used as training samples?",
        "answer": "As training samples, individual scenes of H8 written by Shakespeare, Fletcher, and Massinger are used.",
        "evidence": "In the first experiment we perform an attribution of individual scenes of H8 using the Support Vector Machine as a classifier and the frequencies of 500 most frequent rhythmic types and the frequencies of 500 most frequent words as a feature set. As training samples, individual scenes of plays written by Shakespeare, Fletcher, and Massinger are used that come roughly from the period when H8 was supposedly written, namely:\nShakespeare: The Tragedy of Coriolanus (5 scenes), The Tragedy of Cymbeline (27 scenes), The Winter’s Tale (12 scenes), The Tempest (9 scenes)\nFletcher: Valentinian (21 scenes), Monsieur Thomas (28 scenes), The Woman’s Prize (23 scenes), Bonduca (18 scenes)\nMassinger: The Duke of Milan (10 scenes), The Unnatural Combat (11 scenes), The Renegado (25 scenes)\nAltogether there are thus 53 training samples for Shakespeare, 90 training samples for Fletcher and 46 training samples for Massinger. In order to estimate the accuracy of the model, cross-validation is performed in the following way:\nTo avoid the risk of overfitting which may be caused by testing the model on the scenes from the same play as it was trained on, we do not perform a standard k-fold cross validation. Instead, we classify scenes of each play by a model trained on the rest, i.e. 5 scenes of Shakespeare’s Coriolanus are classified by a model trained on the scenes from the remaining 3 plays by Shakespeare, 4 plays by Fletcher and 5 plays by Massinger, 27 scenes of Cymbeline are classified in the same way and so on.\nSince the training data are imbalanced (which may bias the results), we level the number of training samples per author by random selection.\nTo obtain more representative results, the entire process is repeated 30 times (with a new random selection in each iteration) thus resulting in 30 classifications of each scene.\nFor the sake of comparison of the attribution power of both feature subsets, cross-validations are performed not only of the combined models (500 words $\\cup $ 500 rhythmic types), but also of the words-based models (500 words) and versification-based models (500 rhythmic types) alone.\nAs shown in Table TABREF14, the versification-based models yield a very high accuracy with the recognition of Shakespeare and Fletcher (0.97 to 1 with the exception of Valentinian), yet slightly lower accuracy with the recognition of Massinger (0.81 to 0.88). The accuracy of words-based models remains very high across all three authors (0.95 to 1); in three cases it is nevertheless outperformed by the combined model. We thus may conclude that combined models provide a reliable discriminator between Shakespeare’s, Fletcher’s and Massinger’s styles.\nTable TABREF19 gives the results of the classifiers when applied to the individual scenes of H8 on the basis of which we may conclude:\nIt is very unlikely that Massinger took part in the text of H8. Out of 17 scenes only 2 are attributed to Massinger by any of the models (2.1, 4.2), and in both cases by a mere minority of votes.\nThe probability that the text of H8 is a result of collaboration between Shakespeare and Fletcher is very high: with 7 scenes all the 30 models agree upon Shakespeare’s authorship, with 5 scenes all the 30 models agree upon Fletcher’s authorship.\nOur results correspond to the Spedding’s attribution to a high extent. With the exception of two scenes, the majority of models always predict the same author to which it is attributed by Spedding. The two exceptions are the second scene of act 3, where Spedding supposed mixed authorship, and the first scene of act 4, which was originally attributed to Fletcher.\nAs training samples, individual scenes of plays written by Shakespeare, Fletcher, and Massinger are used that come roughly from the period when H8 was supposedly written, namely: Shakespeare: The Tragedy of Coriolanus (5 scenes), The Tragedy of Cymbeline (27 scenes), The Winter’s Tale (12 scenes), The Tempest (9 scenes) Fletcher: Valentinian (21 scenes), Monsieur Thomas (28 scenes), The Woman’s Prize (23 scenes), Bonduca (18 scenes) Massinger: The Duke of Milan (10 scenes), The Unnatural Combat (11 scenes), The Renegado (25 scenes)",

        "answer": "Yes, it does.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nExperimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.",

        "question": "How do general relation detection methods work with KBQA task?",
        "answer": "Although general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection.",
        "evidence": "Knowledge Base Question Answering (KBQA) systems answer questions by obtaining information from KB tuples BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 . For an input question, these systems typically generate a KB query, which can be executed to retrieve the answers from a KB. Figure 1 illustrates the process used to parse two sample questions in a KBQA system: (a) a single-relation question, which can be answered with a single $<$ head-entity, relation, tail-entity $>$ KB tuple BIBREF6 , BIBREF7 , BIBREF2 ; and (b) a more complex case, where some constraints need to be handled for multiple entities in the question. The KBQA system in the figure performs two key tasks: (1) entity linking, which links $n$ -grams in questions to KB entities, and (2) relation detection, which identifies the KB relation(s) a question refers to.\nThe main focus of this work is to improve the relation detection subtask and further explore how it can contribute to the KBQA system. Although general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection. First, in most general relation detection tasks, the number of target relations is limited, normally smaller than 100. In contrast, in KBQA even a small KB, like Freebase2M BIBREF2 , contains more than 6,000 relation types. Second, relation detection for KBQA often becomes a zero-shot learning task, since some test instances may have unseen relations in the training data. For example, the SimpleQuestions BIBREF2 data set has 14% of the golden test relations not observed in golden training tuples. Third, as shown in Figure 1 (b), for some KBQA tasks like WebQuestions BIBREF0 , we need to predict a chain of relations instead of a single relation. This increases the number of target relation types and the sizes of candidate relation pools, further increasing the difficulty of KB relation detection. Owing to these reasons, KB relation detection is significantly more challenging compared to general relation detection tasks.\nThis paper improves KB relation detection to cope with the problems mentioned above. First, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching. Second, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations. Third, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information. Finally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching.\nIn order to assess how the proposed improved relation detection could benefit the KBQA end task, we also propose a simple KBQA implementation composed of two-step relation detection. Given an input question and a set of candidate entities retrieved by an entity linker based on the question, our proposed relation detection model plays a key role in the KBQA process: (1) Re-ranking the entity candidates according to whether they connect to high confident relations detected from the raw question text by the relation detection model. This step is important to deal with the ambiguities normally present in entity linking results. (2) Finding the core relation (chains) for each topic entity selection from a much smaller candidate entity set after re-ranking. The above steps are followed by an optional constraint detection step, when the question cannot be answered by single relations (e.g., multiple entities in the question). Finally the highest scored query from the above steps is used to query the KB for answers.\nOur main contributions include: (i) An improved relation detection model by hierarchical matching between questions and relations with residual learning; (ii) We demonstrate that the improved relation detector enables our simple KBQA system to achieve state-of-the-art results on both single-relation and multi-relation KBQA tasks.\nAlthough general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection.",

        "question": "What are the two crowdsourcing tasks that are included in the human-AI loop approach?",
        "answer": "Micropost classification followed by keyword discovery, and a unified probabilistic model for expectation inference and model training.",
        "evidence": "Given a set of labeled and unlabeled microposts, our goal is to extract informative keywords and estimate their expectations in order to train a machine learning model. To achieve this goal, our proposed human-AI loop approach comprises two crowdsourcing tasks, i.e., micropost classification followed by keyword discovery, and a unified probabilistic model for expectation inference and model training. Figure FIGREF6 presents an overview of our approach. Next, we describe our approach from a process-centric perspective.\nFollowing previous studies BIBREF1, BIBREF17, BIBREF2, we collect a set of unlabeled microposts $\\mathcal {U}$ from a microblogging platform and post-filter, using an initial (set of) keyword(s), those microposts that are potentially relevant to an event category. Then, we collect a set of event-related microposts (i.e., positively labeled microposts) $\\mathcal {L}$, post-filtering with a list of seed events. $\\mathcal {U}$ and $\\mathcal {L}$ are used together to train a discriminative model (e.g., a deep neural network) for classifying the relevance of microposts to an event. We denote the target model as $p_\\theta (y|x)$, where $\\theta $ is the model parameter to be learned and $y$ is the label of an arbitrary micropost, represented by a bag-of-words vector $x$. Our approach iterates several times $t=\\lbrace 1, 2, \\ldots \\rbrace $ until the performance of the target model converges. Each iteration starts from the initial keyword(s) or the new keyword(s) discovered in the previous iteration. Given such a keyword, denoted by $w^{(t)}$, the iteration starts by sampling microposts containing the keyword from $\\mathcal {U}$, followed by dynamically creating micropost classification tasks and publishing them on a crowdsourcing platform.\nMicropost Classification. The micropost classification task requires crowd workers to label the selected microposts into two classes: event-related and non event-related. In particular, workers are given instructions and examples to differentiate event-instance related microposts and general event-category related microposts. Consider, for example, the following microposts in the context of Cyber attack events, both containing the keyword `hack':\nCredit firm Equifax says 143m Americans' social security numbers exposed in hack\nThis micropost describes an instance of a cyber attack event that the target model should identify. This is, therefore, an event-instance related micropost and should be considered as a positive example. Contrast this with the following example:\nCompanies need to step their cyber security up\nThis micropost, though related to cyber security in general, does not mention an instance of a cyber attack event, and is of no interest to us for event detection. This is an example of a general event-category related micropost and should be considered as a negative example.\nIn this task, each selected micropost is labeled by multiple crowd workers. The annotations are passed to our probabilistic model for expectation inference and model training.\nExpectation Inference & Model Training. Our probabilistic model takes crowd-contributed labels and the model trained in the previous iteration as input. As output, it generates a keyword-specific expectation, denoted as $e^{(t)}$, and an improved version of the micropost classification model, denoted as $p_{\\theta ^{(t)}}(y|x)$. The details of our probabilistic model are given in Section SECREF3.\nKeyword Discovery. The keyword discovery task aims at discovering a new keyword (or a set of keywords) that is most informative for model training with respect to existing keywords. To this end, we first apply the current model $p_{\\theta ^{(t)}}(y|x)$ on the unlabeled microposts $\\mathcal {U}$. For those that contain the keyword $w^{(t)}$, we calculate the disagreement between the model predictions and the keyword-specific expectation $e^{(t)}$:\nand select the ones with the highest disagreement for keyword discovery. These selected microposts are supposed to contain information that can explain the disagreement between the model prediction and keyword-specific expectation, and can thus provide information that is most different from the existing set of keywords for model training.\nFor instance, our study shows that the expectation for the keyword `hack' is 0.20, which means only 20% of the initial set of microposts retrieved with the keyword are event-related. A micropost selected with the highest disagreement (Eq. DISPLAY_FORM7), whose likelihood of being event-related as predicted by the model is $99.9\\%$, is shown as an example below:\nRT @xxx: Hong Kong securities brokers hit by cyber attacks, may face more: regulator #cyber #security #hacking https://t.co/rC1s9CB\nThis micropost contains keywords that can better indicate the relevance to a cyber security event than the initial keyword `hack', e.g., `securities', `hit', and `attack'.\nNote that when the keyword-specific expectation $e^{(t)}$ in Equation DISPLAY_FORM7 is high, the selected microposts will be the ones that contain keywords indicating the irrelevance of the microposts to an event category. Such keywords are also useful for model training as they help improve the model's ability to identify irrelevant microposts.\nTo identify new keywords in the selected microposts, we again leverage crowdsourcing, as humans are typically better than machines at providing specific explanations BIBREF18, BIBREF19. In the crowdsourcing task, workers are first asked to find those microposts where the model predictions are deemed correct. Then, from those microposts, workers are asked to find the keyword that best indicates the class of the microposts as predicted by the model. The keyword most frequently identified by the workers is then used as the initial keyword for the following iteration. In case multiple keywords are selected, e.g., the top-$N$ frequent ones, workers will be asked to perform $N$ micropost classification tasks for each keyword in the next iteration, and the model training will be performed on multiple keyword-specific expectations.\nTo achieve this goal, our proposed human-AI loop approach comprises two crowdsourcing tasks, i.e., micropost classification followed by keyword discovery, and a unified probabilistic model for expectation inference and model training.",

        "question": "What is linux Bootloader",
        "evidence": "A bootloader, also spelled as boot loader or called boot manager and bootstrap loader, is a computer program that is responsible for booting a computer.\n\nWhen a computer is turned off, its software including operating systems, application code, and data‍—‌remains stored on non-volatile memory. When the computer is powered on, it typically does not have an operating system or its loader in random-access memory (RAM). The computer first executes a relatively small program stored in read-only memory (ROM, and later EEPROM, NOR flash) along with some needed data, to initialize RAM (especially on x86 systems), to access the nonvolatile device (usually block device, eg NAND flash) or devices from which the operating system programs and data can be loaded into RAM.\n\nSome earlier computer systems, upon receiving a boot signal from a human operator or a peripheral device, may load a very small number of fixed instructions into memory at a specific location, initialize at least one CPU, and then point the CPU to the instructions and start their execution. These instructions typically start an input operation from some peripheral device (which may be switch-selectable by the operator). Other systems may send hardware commands directly to peripheral devices or I/O controllers that cause an extremely simple input operation (such as \"read sector zero of the system device into memory starting at location 1000\") to be carried out, effectively loading a small number of boot loader instructions into memory; a completion signal from the I/O device may then be used to start execution of the instructions by the CPU.\n\nSmaller computers often use less flexible but more automatic boot loader mechanisms to ensure that the computer starts quickly and with a predetermined software configuration. In many desktop computers, for example, the bootstrapping process begins with the CPU executing software contained in ROM (for example, the BIOS of an IBM PC or an IBM PC compatible) at a predefined address (some CPUs, including the Intel x86 series are designed to execute this software after reset without outside help). This software contains rudimentary functionality to search for devices eligible to participate in booting, and load a small program from a special section (most commonly the boot sector) of the most promising device, typically starting at a fixed entry point such as the start of the sector.",

        "answer": "The authors report Macro-F1 score and F1 scores for each of the 11 classes as the main evaluation metric.",
        "evidence": "In the following experiment, we focus on automatic identification of arguments in the discourse. Our approach is based on supervised and semi-supervised machine learning methods on the gold data Toulmin dataset introduced in section SECREF51 .\nAn argument consists of different components (such as premises, backing, etc.) which are implicitly linked to the claim. In principle one document can contain multiple independent arguments. However, only 4% of the documents in our dataset contain arguments for both sides of the issue. Thus we simplify the task and assume there is only one argument per document.\nGiven the low inter-annotator agreement on the pathos dimension (Table TABREF77 ), we focus solely on recognizing the logical dimension of argument. The pathos dimension of argument remains an open problem for a proper modeling as well as its later recognition.\nSince the smallest annotation unit is a token and the argument components do not overlap, we approach identification of argument components as a sequence labeling problem. We use the BIO encoding, so each token belongs to one of the following 11 classes: O (not a part of any argument component), Backing-B, Backing-I, Claim-B, Claim-I, Premise-B, Premise-I, Rebuttal-B, Rebuttal-I, Refutation-B, Refutation-I. This is the minimal encoding that is able to distinguish two adjacent argument components of the same type. In our data, 48% of all adjacent argument components of the same type are direct neighbors (there are no \"O\" tokens in between).\nWe report Macro- INLINEFORM0 score and INLINEFORM1 scores for each of the 11 classes as the main evaluation metric. This evaluation is performed on the token level, and for each token the predicted label must exactly match the gold data label (classification of tokens into 11 classes).\nAs instances for the sequence labeling model, we chose sentences rather than tokens. During our initial experiments, we observed that building a sequence labeling model for recognizing argument components as sequences of tokens is too fine-grained, as a single token does not convey enough information that could be encoded as features for a machine learner. However, as discussed in section UID73 , the annotations were performed on data pre-segmented to sentences and annotating tokens was necessary only when the sentence segmentation was wrong or one sentence contained multiple argument components. Our corpus consists of 3899 sentences, from which 2214 sentences (57%) contain no argument component. From the remaining ones, only 50 sentences (1%) have more than one argument component. Although in 19 cases (0.5%) the sentence contains a Claim-Premise pair which is an important distinction from the argumentation perspective, given the overall small number of such occurrences, we simplify the task by treating each sentence as if it has either one argument component or none.\nThe approximation with sentence-level units is explained in the example in Figure FIGREF112 . In order to evaluate the expected performance loss using this approximation, we used an oracle that always predicts the correct label for the unit (sentence) and evaluated it against the true labels (recall that the evaluation against the true gold labels is done always on token level). We lose only about 10% of macro INLINEFORM0 score (0.906) and only about 2% of accuracy (0.984). This performance is still acceptable, while allowing to model sequences where the minimal unit is a sentence.\nTable TABREF114 shows the distribution of the classes in the gold data Toulmin, where the labeling was already mapped to the sentences. The little presence of rebuttal and refutation (4 classes account only for 3.4% of the data) makes this dataset very unbalanced.\nWe chose SVMhmm BIBREF111 implementation of Structural Support Vector Machines for sequence labeling. Each sentence ( INLINEFORM0 ) is represented as a vector of real-valued features.\nWe defined the following feature sets:\nFS0: Baseline lexical features\nword uni-, bi-, and tri-grams (binary)\nFS1: Structural, morphological, and syntactic features\nFirst and last 3 tokens. Motivation: these tokens may contain discourse markers or other indicators for argument components, such as “therefore” and “since” for premises or “think” and “believe” for claims.\nRelative position in paragraph and relative position in document. Motivation: We expect that claims are more likely to appear at the beginning or at the end of the document.\nNumber of POS 1-3 grams, dependency tree depth, constituency tree production rules, and number of sub-clauses. Based on BIBREF113 .\nFS2: Topic and sentiment features\n30 features taken from a vector representation of the sentence obtained by using Gibbs sampling on LDA model BIBREF114 , BIBREF115 with 30 topics trained on unlabeled data from the raw corpus. Motivation: Topic representation of a sentence might be valuable for detecting off-topic sentences, namely non-argument components.\nScores for five sentiment categories (from very negative to very positive) obtained from Stanford sentiment analyzer BIBREF116 . Motivation: Claims usually express opinions and carry sentiment.\nFS3: Semantic, coreference, and discourse features\nBinary features from Clear NLP Semantic Role Labeler BIBREF117 . Namely, we extract agent, predicate + agent, predicate + agent + patient + (optional) negation, argument type + argument value, and discourse marker which are based on PropBank semantic role labels. Motivation: Exploit the semantics of Capturing the semantics of the sentences.\nBinary features from Stanford Coreference Chain Resolver BIBREF118 , e.g., presence of the sentence in a chain, transition type (i.e., nominal–pronominal), distance to previous/next sentences in the chain, or number of inter-sentence coreference links. Motivation: Presence of coreference chains indicates links outside the sentence and thus may be informative, for example, for classifying whether the sentence is a part of a larger argument component.\nResults of a PTDB-style discourse parser BIBREF119 , namely the type of discourse relation (explicit, implicit), presence of discourse connectives, and attributions. Motivation: It has been claimed that discourse relations play a role in argumentation mining BIBREF120 .\nFS4: Embedding features\n300 features from word embedding vectors using word embeddings trained on part of the Google News dataset BIBREF121 . In particular, we sum up embedding vectors (dimensionality 300) of each word, resulting into a single vector for the entire sentence. This vector is then directly used as a feature vector. Motivation: Embeddings helped to achieve state-of-the-art results in various NLP tasks BIBREF116 , BIBREF122 .\nExcept the baseline lexical features, all feature types are extracted not only for the current sentence INLINEFORM0 , but also for INLINEFORM1 preceding and subsequent sentences, namely INLINEFORM2 , INLINEFORM3 , INLINEFORM4 INLINEFORM5 , INLINEFORM6 , where INLINEFORM7 was empirically set to 4. Each feature is then represented with a prefix to determine its relative position to the current sequence unit.\nLet us first discuss the upper bounds of the system. Performance of the three human annotators is shown in the first column of Table TABREF139 (results are obtained from a cumulative confusion matrix). The overall Macro- INLINEFORM0 score is 0.602 (accuracy 0.754). If we look closer at the different argument components, we observe that humans are good at predicting claims, premises, backing and non-argumentative text (about 0.60-0.80 INLINEFORM1 ), but on rebuttal and refutation they achieve rather low scores. Without these two components, the overall human Macro- INLINEFORM2 would be 0.707. This trend follows the inter-annotator agreement scores, as discussed in section UID75 .\nIn our experiments, the feature sets were combined in the bottom-up manner, starting with the simple lexical features (FS0), adding structural and syntactic features (FS1), then adding topic and sentiment features (FS2), then features reflecting the discourse structure (FS3), and finally enriched with completely unsupervised latent vector space representation (FS4). In addition, we were gradually removing the simple features (e.g., without lexical features, without syntactic features, etc.) to test the system with more “abstract” feature sets (feature ablation). The results are shown in Table TABREF139 .\nThe overall best performance (Macro- INLINEFORM0 0.251) was achieved using the rich feature sets (01234 and 234) and significantly outperformed the baseline as well as other feature sets. Classification of non-argumentative text (the \"O\" class) yields about 0.7 INLINEFORM1 score even in the baseline setting. The boundaries of claims (Cla-B), premises (Pre-B), and backing (Bac-B) reach in average lower scores then their respective inside tags (Cla-I, Pre-I, Bac-I). It can be interpreted such that the system is able to classify that a certain sentence belongs to a certain argument component, but the distinction whether it is a beginning of the argument component is harder. The very low numbers for rebuttal and refutation have two reasons. First, these two argument components caused many disagreements in the annotations, as discussed in section UID86 , and were hard to recognize for the humans too. Second, these four classes have very few instances in the corpus (about 3.4%, see Table TABREF114 ), so the classifier suffers from the lack of training data.\nThe results for the in-domain cross validation scenario are shown in Table TABREF140 . Similarly to the cross-validation scenario, the overall best results were achieved using the largest feature set (01234). For mainstreaming and red-shirting, the best results were achieved using only the feature set 4 (embeddings). These two domains contain also fewer documents, compared to other domains (refer to Table TABREF71 ). We suspect that embeddings-based features convey important information when not enough in-domain data are available. This observation will become apparent in the next experiment.\nThe cross-domain experiments yield rather poor results for most of the feature combinations (Table TABREF141 ). However, using only feature set 4 (embeddings), the system performance increases rapidly, so it is even comparable to numbers achieved in the in-domain scenario. These results indicate that embedding features generalize well across domains in our task of argument component identification. We leave investigating better performing vector representations, such as paragraph vectors BIBREF123 , for future work.\nError analysis based on the probabilistic confusion matrix BIBREF124 shown in Table TABREF142 reveals further details. About a half of the instances for each class are misclassified as non-argumentative (the \"O\" prediction).\nBacking-B is often confused with Premise-B (12%) and Backing-I with Premise-I (23%). Similarly, Premise-I is misclassified as Backing-I in 9%. This shows that distinguishing between backing and premises is not easy because these two components are similar such that they support the claim, as discussed in section UID86 . We can also see that the misclassification is consistent among *-B and *-I tags.\nRebuttal is often misclassified as Premise (28% for Rebuttal-I and 18% for Rebuttal-B; notice again the consistency in *-B and *-I tags). This is rather surprising, as one would expect that rebuttal would be confused with a claim, because its role is to provide an opposing view.\nRefutation-B and Refutation-I is misclassified as Premise-I in 19% and 27%, respectively. This finding confirms the discussion in section UID86 , because the role of refutation is highly context-dependent. In a pragmatic perspective, it is put forward to indirectly support the claim by attacking the rebuttal, thus having a similar function to the premise.\nWe manually examined miss-classified examples produced the best-performing system to find out which phenomena pose biggest challenges. Properly detecting boundaries of argument components caused problems, as shown in Figure FIGREF146 (a). This goes in line with the granularity annotation difficulties discussed in section UID86 . The next example in Figure FIGREF146 (b) shows that even if boundaries of components were detected precisely, the distinction between premise and backing fails. The example also shows that in some cases, labeling on clause level is required (left-hand side claim and premise) but the approximation in the system cannot cope with this level of detail (as explained in section UID111 ). Confusing non-argumentative text and argument components by the system is sometimes plausible, as is the case of the last rhetorical question in Figure FIGREF146 (c). On the other hand, the last example in Figure FIGREF146 (d) shows that some claims using figurative language were hard to be identified. The complete predictions along with the gold data are publicly available.\nSVMhmm offers many hyper-parameters with suggested default values, from which three are of importance. Parameter INLINEFORM0 sets the order of dependencies of transitions in HMM, parameter INLINEFORM1 sets the order of dependencies of emissions in HMM, and parameter INLINEFORM2 represents a trading-off slack versus magnitude of the weight-vector. For all experiments, we set all the hyper-parameters to their default values ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ). Using the best performing feature set from Table TABREF139 , we experimented with a grid search over different values ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) but the results did not outperform the system trained with default parameter values.\nThe INLINEFORM0 scores might seem very low at the first glance. One obvious reason is the actual performance of the system, which gives a plenty of room for improvement in the future. But the main cause of low INLINEFORM2 numbers is the evaluation measure — using 11 classes on the token level is very strict, as it penalizes a mismatch in argument component boundaries the same way as a wrongly predicted argument component type. Therefore we also report two another evaluation metrics that help to put our results into a context.\nKrippendorff's INLINEFORM0 — It was also used for evaluating inter-annotator agreement (see section UID75 ).\nBoundary similarity BIBREF125 — Using this metric, the problem is treated solely as a segmentation task without recognizing the argument component types.\nAs shown in Table TABREF157 (the Macro- INLINEFORM0 scores are repeated from Table TABREF139 ), the best-performing system achieves 0.30 score using Krippendorf's INLINEFORM1 , which is in the middle between the baseline and the human performance (0.48) but is considered as poor from the inter-annotator agreement point of view BIBREF54 . The boundary similarity metrics is not directly suitable for evaluating argument component classification, but reveals a sub-task of finding the component boundaries. The best system achieved 0.32 on this measure. Vovk2013MT used this measure to annotate argument spans and his annotators achieved 0.36 boundary similarity score. Human annotators in BIBREF125 reached 0.53 boundary similarity score.\nThe overall performance of the system is also affected by the accuracy of individual NPL tools used for extracting features. One particular problem is that the preprocessing models we rely on (POS, syntax, semantic roles, coreference, discourse; see section UID115 ) were trained on newswire corpora, so one has to expect performance drop when applied on user-generated content. This is however a well-known issue in NLP BIBREF126 , BIBREF127 , BIBREF128 .\nTo get an impression of the actual performance of the system on the data, we also provide the complete output of our best performing system in one PDF document together with the gold annotations in the logos dimension side by side in the accompanying software package. We believe this will help the community to see the strengths of our model as well as possible limitations of our current approaches.\nWe report Macro-F1 score and F1 scores for each of the 11 classes as the main evaluation metric.",

In our experiments, all context-aware models consider one preceding sentence as context. The evaluation according to the distance of the antecedent in Table TABREF35 confirms that the subset of sentences with antecedent distance 1 benefits most from the tested context-aware models (up to +20 percentage points accuracy). However, we note two surprising patterns:\nThe first observation can be explained by the distribution of German pronouns in the test set. The further away the antecedent, the higher the percentage of it INLINEFORM0 es cases, which are the majority class, and thus the class that will be predicted most often if evidence for other classes is lacking. We speculate that this is due to our more permissive extraction heuristics for it INLINEFORM1 es.\nWe attribute the second observation to the existence of coreference chains where the preceding sentence contains a pronoun that refers to the same nominal antecedent as the pronoun in the current sentence. Consider the example in Table TABREF36 : The nominal antecedent of it in the current sentence is door, Tür in German with feminine gender. The nominal antecedent occurs two sentences before the current sentence, but the German sentence in between contains the pronoun sie, which is a useful signal for the context-aware models, even though they cannot know the nominal antecedent.\nNote that only models aware of target-side context can benefit from such circumstances: The s-hier models as well as the Transformer model by BIBREF8 only see source side context, which results in lower accuracy if the distance to the antecedent is INLINEFORM0 1, see Table TABREF35 .\nWhile such coreference chains complicate the interpretation of the results, we note that improvements on inter-sentential anaphora with antecedent distance INLINEFORM0 are relatively small (compared to distance 1), and that performance is still relatively poor (especially for the minority classes er and sie). We encourage evaluation of wider-context models on this subset, which is still large thanks to the size of the full test set.\nRegarding the comparison of different context-aware architectures, our results demonstrate the effectiveness of parameter sharing between the main encoder (or decoder) and the contextual encoder. We observe an improvement of 5 percentage points from s-hier-to-2 to s-hier-to-2.tied, and 4 percentage points from s-t-hier to s-t-hier.tied. Context encoders introduce a large number of extra parameters, while inter-sentential context is only relevant for a relatively small number of predictions. We hypothesize that the training signal is thus too weak to train a strong contextual encoder in an end-to-end fashion without parameter sharing. Our results also confirm the finding by BIBREF9 that multi-encoder architectures, specifically s-hier-to-2(.tied), can outperform a simple concatenation system in the translation of coreferential pronouns.\nThe Transformer-based models perform strongest on pronouns with intra-segmental antecedent, outperforming the recurrent baseline by 9–18 percentage points. This is likely an effect of increased model depth and the self-attentional architecture in this set of experiments. The model by BIBREF8 only uses source context, and outperforms the most comparable RNN system, s-hier.tied. However, the Transformer-based concat22 slightly underperforms the RNN-based concat22, and we consider it future research how to better exploit target context with Transformer-based models.\nThis suggests that the architectural changes for the context-aware models do not degrade overall translation quality.",

        "evidence": "Adversarial examples are generally minimal perturbations applied to the input data in an effort to expose the regions of the input space where a trained model performs poorly. Prior works BIBREF0, BIBREF1 have demonstrated the ability of an adversary to evade state-of-the-art classifiers by carefully crafting attack examples which can be even imperceptible to humans. Following such approaches, there has been a number of techniques aimed at generating adversarial examples BIBREF2, BIBREF3. Depending on the degree of access to the target model, an adversary may operate in one of the two different settings: (a) black-box setting, where an adversary doesn't have access to target model's internal architecture or its parameters, (b) white-box setting, where an adversary has access to the target model, its parameters, and input feature representations. In both these settings, the adversary cannot alter the training data or the target model itself. Depending on the purpose of the adversary, adversarial attacks can be categorized as (a) targeted attack and (b) non-targeted attack. In a targeted attack, the output category of a generated example is intentionally controlled to a specific target category with limited change in semantic information. While a non-targeted attack doesn't care about the category of misclassified results.\nMost of the prior work has focused on image classification models where adversarial examples are obtained by introducing imperceptible changes to pixel values through optimization techniques BIBREF4, BIBREF5. However, generating natural language adversarial examples can be challenging mainly due to the discrete nature of text samples. Continuous data like image or speech is much more tolerant to perturbations compared to text BIBREF6. In textual domain, even a small perturbation is clearly perceptible and can completely change the semantics of the text. Another challenge for generating adversarial examples relates to identifying salient areas of the text where a perturbation can be applied successfully to fool the target classifier. In addition to fooling the target classifier, the adversary is designed with different constraints depending on the task and its motivations BIBREF7. In our work, we focus on constraining our adversary to craft examples with semantic preservation and minimum perturbations to the input text.\nGiven different settings of the adversary, there are other works that have designed attacks in “gray-box” settings BIBREF8, BIBREF9, BIBREF10. However, the definitions of “gray-box” attacks are quite different in each of these approaches. In this paper, we focus on “black-box” setting where we assume that the adversary possesses a limited set of labeled data, which is different from the target's training data, and also has an oracle access to the system, i.e., one can query the target classifier with any input and get its corresponding predictions. We propose an effective technique to generate adversarial examples in a black-box setting. We develop an Adversarial Example Generator (AEG) model that uses a reinforcement learning framing to generate adversarial examples. We evaluate our models using a word-based BIBREF11 and character-based BIBREF12 text classification model on benchmark classification tasks: sentiment classification and news categorization. The adversarial sequences generated are able to effectively fool the classifiers without changing the semantics of the text. Our contributions are as follows:\nWe propose a black-box non-targeted attack strategy by combining ideas of substitute network and adversarial example generation. We formulate it as a reinforcement learning task.\nWe introduce an encoder-decoder that operates over words and characters of an input text and empowers the model to introduce word and character-level perturbations.\nWe adopt a self-critical sequence training technique to train our model to generate examples that can fool or increase the probability of misclassification in text classifiers.\nWe evaluate our models on two different datasets associated with two different tasks: IMDB sentiment classification and AG's news categorization task. We run ablation studies on various components of the model and provide insights into decisions of our model.\nWe propose an effective technique to generate adversarial examples in a black-box setting.",

The Boeing 737 series aircraft is the most popular commercial jet in the world. In March 2019 and December 2020, the Boeing 737 Max commercial jets belonging to Ethiopian and LION Air crashed, grounding the 737 Max jets. These incidents triggered the crisis at Boeing. \n\nThe Boeing 737 Max crisis is a classic example of chained unethical behaviors exhibited by an organization and how one unethical behavior quickly led to another in an attempt to cover up the previous one. \n\nMotivated blindness \n\nMotivated blindness was the initial cause for the people involved in the 737 Max jet design. It started with Boeing’s chief technical test pilot, David Forkner, who repeatedly spotted erratic behavior on the jets MCAS (Maneuvering Characteristics Augmentation System). Despite egregious MCAS, David later urged FAA (Federal Aviation Authority) to remove the MCAS mentioned from the 737 Max instruction manual. Boeing management failed to overlook David ForKner’s and other faults and chose to remain ignorant. \n\nIndirect blindness \n\nSimilarly, a lot is afoul with FAA. Months before the crash of 2 jets, Boeing had known about the issues and delayed the flight data submission to FAA. Despite the warnings from FAA, Boeing got away with it quickly. The indirect blindness of the FAA added insult to injury to the crisis. \n\nSlippery slope \n\nBoeing was on a slippery slope, and the downward spiral continued with David Forkner requesting FAA to remove the mentions of MCAS from the jet’s instruction manual. Another test pilot, Gustavsson, claimed that David Forkner kept him out of the loop. \n \nOvervaluing outcomes \n\nOn the whole, Boeing was unaware of the looming crisis and, at every stage, was overvaluing the outcomes of getting the jet out of the production lines and getting it FAA-approved. \n\nRecommendations \n\n The managers at Boeing must implement processes that root out conflicts of interest. For example, when David Forkner captured the erratic behavior of MCAS, the stringent process to capture test data and the data must be published to a governance board to resolve any conflict of interest. \n\nSimilarly, for FAA-related transactions and interactions, the governance board must oversee whether the transactions might invite unethical behavior and take ownership of the implications. \n\nBoeing’s governance board must continuously monitor for trivial ethical infractions and address them immediately.

The effectiveness of BN adaptation for domain shift is well explored in the existing related literature (Nado et al., 2020; Schneider et al., 2020; Wang et al.,2021). Motivated by the problems of test-time BN methods, we propose a BN  adaptation with a few-shot setting.",
        "evidence": "While deep neural networks have demonstrated remarkable ability in representation learning, their performance relies heavily on the assumption that training (source) and test (target) data distributions are the same. Real-world data collection is often resource-constrained, such that test samples may be subject to domain shift, also known as covariate shift, due to factors such as illumination, pose, style and data collection procedures. To prevent severe performance degradation when models are deployed, adaptation to the target distribution is needed.\nA range of methods to address domain shift have been developed, with varying requirements on source and target domain data. Domain generalization considers generalization without seeing target data, but existing methods still have a considerable generalization gap. On the other hand, domain adaptation (DA) assumes the availability of target data during training. Most DA methods work under the vanilla unsupervised DA (UDA) setting, taking that labelled source and unlabelled target data are fully accessible for joint training. Some methods have been proposed under the few-shot DA setting, which assume that labelled source data and a few labelled target samples are available. Recent work is shifting towards a more challenging setting of source-free UDA, where a pre-trained source model is adapted with only unlabelled target data. However, these methods require access to the entire target dataset during adaptation.\nVery recently, test-time adaptation methods have been proposed to continuously adapt during test time with streaming unlabelled target data, by updating batch normalization (BN) layers batch-by-batch. However, these methods face 3 main challenges: 1) estimation performance is dependent on large batch size to estimate BN parameters and statistics, 2) test samples need to be class-balanced which may not be practical in real-world deployment, 3) there is no guarantee self-supervision objectives can correct domain shift without using any target domain label information. For instance, entropy minimization can lead to undesired trivial solutions where all outputs \"collapse\" to one or a few classes.\nMotivated by the problems of test-time adaptation methods, we propose a challenging but practical source-free DA setting by adapting a pre-trained source model using k-shot support from target do- shows existing settings in the DA literature and the proposed setting. Considerations for real-world usage motivates our proposed source-free k-shot setting to address domain shift:\n• Data availability: Our setting helps to protect privacy of the source domains, and has low requirements for target data availability of only k labelled samples per class during adaptation. During testing, test batch can be of any size with no restrictions. • Inference efficiency: Model parameters are not updated at test-time.\n• Accuracy: Our setting is not dependent on test-time data streaming conditions and selfsupervised objectives, and hence enables more reliable and accurate adaptation.\nWe propose a k-shot method to adapt batch normalization (BN) layers of deep source models to address domain shift. As far as we know, our work is the first source-free domain adaptation method with a few-shot setting. Although BN layer modulation has been explored in existing literature, reliably optimizing BN layers with extremely few support samples is a new and challenging problem. Naively optimizing high-dimensional parameters in BN layers risks a severely ill-posed problem caused by data scarcity, and can result in unreliable estimates that easily over-fit to the small support set.\nIn this work, we introduce a new parameterization of BN layers, and approximate the optimal highdimensional target domain BN statistics by a linear combination of spanning vectors representing both source and target domains. Specifically, we linearly combine a small set of spanning vectors obtained from source domain BN statistics and support set, and optimize the combination coefficients by supervised loss on the support set. This significantly reduces the number of parameters to adapt on BN layers. Our proposed method is inspired by the success of controlling sample stylization through BN layers, and we aim to approximate the optimal style to stylize the target domain samples to best address domain shift. We evaluate the proposed method on different image classification benchmark datasets. We provide experimental validations and comparisons with state-of-the-art methods to demonstrate that our approach compares favorably in adaptation accuracy.\nVery recently, test-time adaptation methods (Nado et al., 2020; Schneider et al., 2020; Wang et al., 2021a) have been proposed to continuously adapt during test time with streaming unlabelled target data, by updating batch normalization (BN) layers batch-by-batch.

        "answer": "The Masters was started by amateur champion Bobby Jones and investment banker Clifford Roberts. After his grand slam in 1930, Jones acquired the former plant nursery and co-designed Augusta National with course architect Alister MacKenzie. First played 89 years ago in 1934, the tournament is an official money event on the PGA Tour, the European Tour, and the Japan Golf Tour. The field of players is smaller than those of the other major championships because it is an invitational event, held by the Augusta National Golf Club.\n\nThe tournament has a number of traditions. Since 1949, a green jacket has been awarded to the champion, who must return it to the clubhouse one year after his victory, although it remains his personal property and is stored with other champions' jackets in a specially designated cloakroom. In most instances, only a first-time and currently reigning champion may remove his jacket from the club grounds. A golfer who wins the event multiple times uses the same green jacket awarded upon his initial win (unless they need to be re-fitted with a new jacket). The Champions Dinner, inaugurated by Ben Hogan in 1952, is held on the Tuesday before each tournament, and is open only to past champions and certain board members of the Augusta National Golf Club. Beginning in 1963, legendary golfers, usually past champions, have hit an honorary tee shot on the morning of the first round to commence play. These have included Fred McLeod, Jock Hutchinson, Gene Sarazen, Sam Snead, Byron Nelson, Arnold Palmer, Jack Nicklaus, Gary Player, Lee Elder, and Tom Watson. Since 1960, a semi-social contest at the par-3 course has been played on Wednesday, the day before the first round.\n\nNicklaus has the most Masters wins, with six between 1963 and 1986. Tiger Woods won five between 1997 and 2019. Palmer won four between 1958 and 1964. Five have won three titles at Augusta: Jimmy Demaret, Sam Snead, Gary Player, Nick Faldo, and Phil Mickelson. Player, from South Africa, was the first non-American player to win the tournament, in 1961; the second was Seve Ballesteros of Spain, the champion in 1980 and 1983.\n\nThe Augusta National course first opened 90 years ago in 1933 and has been modified many times by different architects.

        "answer": "No.there isn't.",
        "evidence": "The goal of this study was to annotate documents on a detailed level with respect to an argumentation model. First, we will present the annotation scheme. Second, we will describe the annotation process. Finally, we will evaluate the agreement and draw some conclusions.\nGiven the theoretical background briefly introduced in section SECREF2 , we motivate our selection of the argumentation model by the following requirements. First, the scope of this work is to capture argumentation within a single document, thus focusing on micro-level models. Second, there should exist empirical evidence that such a model has been used for analyzing argumentation in previous works, so it is likely to be suitable for our purposes of argumentative discourse analysis in user-generated content. Regarding the first requirement, two typical examples of micro-level models are the Toulmin's model BIBREF36 and Walton's schemes BIBREF55 . Let us now elaborate on the second requirement.\nWalton's argumentation schemes are claimed to be general and domain independent. Nevertheless, evidence from the computational linguistics field shows that the schemes lack coverage for analyzing real argumentation in natural language texts. In examining real-world political argumentation from BIBREF56 , Walton.2012 found out that 37.1% of the arguments collected did not fit any of the fourteen schemes they chose so they created new schemes ad-hoc. Cabrio2013b selected five argumentation schemes from Walton and map these patterns to discourse relation categories in the Penn Discourse TreeBank (PDTB) BIBREF48 , but later they had to define two new argumentation schemes that they discovered in PDTB. Similarly, Song.et.al.2014 admitted that the schemes are ambiguous and hard to directly apply for annotation, therefore they modified the schemes and created new ones that matched the data.\nAlthough Macagno.Konstantinidou.2012 show several examples of two argumentation schemes applied to few selected arguments in classroom experiments, empirical evidence presented by Anthony.Kim.2014 reveals many practical and theoretical difficulties of annotating dialogues with schemes in classroom deliberation, providing many details on the arbitrary selection of the sub-set of the schemes, the ambiguity of the scheme definitions, concluding that the presence of the authors during the experiment was essential for inferring and identifying the argument schemes BIBREF57 .\nAlthough this model (refer to section SECREF21 ) was designed to be applicable to real-life argumentation, there are numerous studies criticizing both the clarity of the model definition and the differentiation between elements of the model. Ball1994 claims that the model can be used only for the most simple arguments and fails on the complex ones. Also Freeman1991 and other argumentation theorists criticize the usefulness of Toulmin's framework for the description of real-life argumentative texts. However, others have advocated the model and claimed that it can be applied to the people's ordinary argumenation BIBREF58 , BIBREF59 .\nA number of studies (outside the field of computational linguistics) used Toulmin's model as their backbone argumentation framework. Chambliss1995 experimented with analyzing 20 written documents in a classroom setting in order to find the argument patterns and parts. Simosi2003 examined employees' argumentation to resolve conflicts. Voss2006 analyzed experts' protocols dealing with problem-solving.\nThe model has also been used in research on computer-supported collaborative learning. Erduran2004 adapt Toulmin's model for coding classroom argumentative discourse among teachers and students. Stegmann2011 builds on a simplified Toulmin's model for scripted construction of argument in computer-supported collaborative learning. Garcia-Mila2013 coded utterances into categories from Toulmin's model in persuasion and consensus-reaching among students. Weinberger.Fischer.2006 analyze asynchronous discussion boards in which learners engage in an argumentative discourse with the goal to acquire knowledge. For coding the argument dimension, they created a set of argumentative moves based on Toulmin's model. Given this empirical evidence, we decided to build upon the Toulmin's model.\nIn this annotation task, a sequence of tokens (e.g. a phrase, a sentence, or any arbitrary text span) is labeled with a corresponding argument component (such as the claim, the grounds, and others). There are no explicit relations between these annotation spans as the relations are implicitly encoded in the pragmatic function of the components in the Toulmin's model.\nIn order to prove the suitability of the Toulmin's model, we analyzed 40 random documents from the gold data persuasive dataset using the original Toulmin's model as presented in section SECREF21 . We took into account sever criteria for assessment, such as frequency of occurrence of the components or their importance for the task. We proposed some modifications of the model based on the following observations.\nAuthors do not state the degree of cogency (the probability of their claim, as proposed by Toulmin). Thus we omitted qualifier from the model due to its absence in the data.\nThe warrant as a logical explanation why one should accept the claim given the evidence is almost never stated. As pointed out by BIBREF37 , “data are appealed to explicitly, warrants implicitly.” This observation has also been made by Voss2006. Also, according to [p. 205]Eemeren.et.al.1987, the distinction of warrant is perfectly clear only in Toulmin’s examples, but the definitions fail in practice. We omitted warrant from the model.\nRebuttal is a statement that attacks the claim, thus playing a role of an opposing view. In reality, the authors often attack the presented rebuttals by another counter-rebuttal in order to keep the whole argument's position consistent. Thus we introduced a new component – refutation – which is used for attacking the rebuttal. Annotation of refutation was conditioned of explicit presence of rebuttal and enforced by the annotation guidelines. The chain rebuttal–refutation is also known as the procatalepsis figure in rhetoric, in which the speaker raises an objection to his own argument and then immediately answers it. By doing so, the speaker hopes to strengthen the argument by dealing with possible counter-arguments before the audience can raise them BIBREF43 .\nThe claim of the argument should always reflect the main standpoint with respect to the discussed controversy. We observed that this standpoint is not always explicitly expressed, but remains implicit and must be inferred by the reader. Therefore, we allow the claim to be implicit. In such a case, the annotators must explicitly write down the (inferred) stance of the author.\nBy definition, the Toulmin's model is intended to model single argument, with the claim in its center. However, we observed in our data, that some authors elaborate on both sides of the controversy equally and put forward an argument for each side (by argument here we mean the claim and its premises, backings, etc.). Therefore we allow multiple arguments to be annotated in one document. At the same time, we restrained the annotators from creating complex argument hierarchies.\nToulmin's grounds have an equivalent role to a premise in the classical view on an argument BIBREF15 , BIBREF60 in terms that they offer the reasons why one should accept the standpoint expressed by the claim. As this terminology has been used in several related works in the argumentation mining field BIBREF7 , BIBREF61 , BIBREF62 , BIBREF11 , we will keep this convention and denote the grounds as premises.\nOne of the main critiques of the original Toulmin's model was the vague distinction between grounds, warrant, and backing BIBREF63 , BIBREF64 , BIBREF65 . The role of backing is to give additional support to the warrant, but there is no warrant in our model anymore. However, what we observed during the analysis, was a presence of some additional evidence. Such evidence does not play the role of the grounds (premises) as it is not meant as a reason supporting the claim, but it also does not explain the reasoning, thus is not a warrant either. It usually supports the whole argument and is stated by the author as a certain fact. Therefore, we extended the scope of backing as an additional support to the whole argument.\nThe annotators were instructed to distinguish between premises and backing, so that premises should cover generally applicable reasons for the claim, whereas backing is a single personal experience or statements that give credibility or attribute certain expertise to the author. As a sanity check, the argument should still make sense after removing backing (would be only considered “weaker”).\nWe call the model as a modified Toulmin's model. It contains five argument components, namely claim, premise, backing, rebuttal, and refutation. When annotating a document, any arbitrary token span can be labeled with an argument component; the components do not overlap. The spans are not known in advance and the annotator thus chooses the span and the component type at the same time. All components are optional (they do not have to be present in the argument) except the claim, which is either explicit or implicit (see above). If a token span is not labeled by any argument component, it is not considered as a part of the argument and is later denoted as none (this category is not assigned by the annotators).\nAn example analysis of a forum post is shown in Figure FIGREF65 . Figure FIGREF66 then shows a diagram of the analysis from that example (the content of the argument components was shortened or rephrased).\nThe annotation experiment was split into three phases. All documents were annotated by three independent annotators, who participated in two training sessions. During the first phase, 50 random comments and forum posts were annotated. Problematic cases were resolved after discussion and the guidelines were refined. In the second phase, we wanted to extend the range of annotated registers, so we selected 148 comments and forum posts as well as 41 blog posts. After the second phase, the annotation guidelines were final.\nIn the final phase, we extended the range of annotated registers and added newswire articles from the raw corpus in order to test whether the annotation guidelines (and inherently the model) is general enough. Therefore we selected 96 comments/forum posts, 8 blog posts, and 8 articles for this phase. A detailed inter-annotator agreement study on documents from this final phase will be reported in section UID75 .\nThe annotations were very time-consuming. In total, each annotator spent 35 hours by annotating in the course of five weeks. Discussions and consolidation of the gold data took another 6 hours. Comments and forum posts required on average of 4 minutes per document to annotate, while blog posts and articles on average of 14 minutes per document. Examples of annotated documents from the gold data are listed in Appendix UID158 .\nWe discarded 11 documents out of the total 351 annotated documents. Five forum posts, although annotated as persuasive in the first annotation study, were at a deeper look a mixture of two or more posts with missing quotations, therefore unsuitable for analyzing argumentation. Three blog posts and two articles were found not to be argumentative (the authors took no stance to the discussed controversy) and one article was an interview, which the current model cannot capture (a dialogical argumentation model would be required).\nFor each of the 340 documents, the gold standard annotations were obtained using the majority vote. If simple majority voting was not possible (different boundaries of the argument component together with a different component label), the gold standard was set after discussion among the annotators. We will refer to this corpus as the gold standard Toulmin corpus. The distribution of topics and registers in this corpus in shown in Table TABREF71 , and Table TABREF72 presents some lexical statistics.\nBased on pre-studies, we set the minimal unit for annotation as token. The documents were pre-segmented using the Stanford Core NLP sentence splitter BIBREF69 embedded in the DKPro Core framework BIBREF70 . Annotators were asked to stick to the sentence level by default and label entire pre-segmented sentences. They should switch to annotations on the token level only if (a) a particular sentence contained more than one argument component, or (b) if the automatic sentence segmentation was wrong. Given the “noise” in user-generated Web data (wrong or missing punctuation, casing, etc.), this was often the case.\nAnnotators were also asked to rephrase (summarize) each annotated argument component into a simple statement when applicable, as shown in Figure FIGREF66 . This was used as a first sanity checking step, as each argument component is expected to be a coherent discourse unit. For example, if a particular occurrence of a premise cannot be summarized/rephrased into one statement, this may require further splitting into two or more premises.\nFor the actual annotations, we developed a custom-made web-based application that allowed users to switch between different granularity of argument components (tokens or sentences), to annotate the same document in different argument “dimensions” (logos and pathos), and to write summary for each annotated argument component.\nAs a measure of annotation reliability, we rely on Krippendorff's unitized alpha ( INLINEFORM0 ) BIBREF71 . To the best of our knowledge, this is the only agreement measure that is applicable when both labels and boundaries of segments are to be annotated.\nAlthough the measure has been used in related annotation works BIBREF61 , BIBREF7 , BIBREF72 , there is one important detail that has not been properly communicated. The INLINEFORM0 is computed over a continuum of the smallest units, such as tokens. This continuum corresponds to a single document in the original Krippendorff's work. However, there are two possible extensions to multiple documents (a corpus), namely (a) to compute INLINEFORM1 for each document first and then report an average value, or (b) to concatenate all documents into one large continuum and compute INLINEFORM2 over it. The first approach with averaging yielded extremely high the standard deviation of INLINEFORM3 (i.e., avg. = 0.253; std. dev. = 0.886; median = 0.476 for the claim). This says that some documents are easy to annotate while others are harder, but interpretation of such averaged value has no evidence either in BIBREF71 or other papers based upon it. Thus we use the other methodology and treat the whole corpus as a single long continuum (which yields in the example of claim 0.541 INLINEFORM4 ).\nTable TABREF77 shows the inter-annotator agreement as measured on documents from the last annotation phase (see section UID67 ). The overall INLINEFORM0 for all register types, topics, and argument components is 0.48 in the logos dimension (annotated with the modified Toulmin's model). Such agreement can be considered as moderate by the measures proposed by Landis.Koch.1977, however, direct interpretation of the agreement value lacks consensus BIBREF54 . Similar inter-annotator agreement numbers were achieved in the relevant works in argumentation mining (refer to Table TABREF33 in section SECREF31 ; although most of the numbers are not directly comparable, as different inter-annotator metrics were used on different tasks).\nThere is a huge difference in INLINEFORM0 regarding the registers between comments + forums posts ( INLINEFORM1 0.60, Table TABREF77 a) and articles + blog posts ( INLINEFORM2 0.09, Table TABREF77 b) in the logos dimension. If we break down the value with respect to the individual argument components, the agreement on claim and premise is substantial in the case of comments and forum posts (0.59 and 0.69, respectively). By contrast, these argument components were annotated only with a fair agreement in articles and blog posts (0.22 and 0.24, respectively).\nAs can be also observed from Table TABREF77 , the annotation agreement in the logos dimension varies regarding the document topic. While it is substantial/moderate for prayer in schools (0.68) or private vs. public schools (0.44), for some topics it remains rather slight, such as in the case of redshirting (0.14) or mainstreaming (0.08).\nFirst, we examine the disagreement in annotations by posing the following research question: are there any measurable properties of the annotated documents that might systematically cause low inter-annotator agreement? We use Pearson's correlation coefficient between INLINEFORM0 on each document and the particular property under investigation. We investigated the following set of measures.\nFull sentence coverage ratio represents a ratio of argument component boundaries that are aligned to sentence boundaries. The value is 1.0 if all annotations in the particular document are aligned to sentences and 0.0 if no annotations match the sentence boundaries. Our hypothesis was that automatic segmentation to sentences was often incorrect, therefore annotators had to switch to the token level annotations and this might have increased disagreement on boundaries of the argument components.\nDocument length, paragraph length and average sentence length. Our hypotheses was that the length of documents, paragraphs, or sentences negatively affects the agreement.\nReadability measures. We tested four standard readability measures, namely Ari BIBREF73 , Coleman-Liau BIBREF74 , Flesch BIBREF75 , and Lix BIBREF76 to find out whether readability of the documents plays any role in annotation agreement.\nCorrelation results are listed in Table TABREF82 . We observed the following statistically significant ( INLINEFORM0 ) correlations. First, document length negatively correlates with agreement in comments. The longer the comment was the lower the agreement was. Second, average paragraph length negatively correlates with agreement in blog posts. The longer the paragraphs in blogs were, the lower agreement was reached. Third, all readability scores negatively correlate with agreement in the public vs. private school domain, meaning that the more complicated the text in terms of readability is, the lower agreement was reached. We observed no significant correlation in sentence coverage and average sentence length measures. We cannot draw any general conclusion from these results, but we can state that some registers and topics, given their properties, are more challenging to annotate than others.\nAnother qualitative analysis of disagreements between annotators was performed by constructing a probabilistic confusion matrix BIBREF77 on the token level. The biggest disagreements, as can be seen in Table TABREF85 , is caused by rebuttal and refutation confused with none (0.27 and 0.40, respectively). This is another sign that these two argument components were very hard to annotate. As shown in Table TABREF77 , the INLINEFORM5 was also low – 0.08 for rebuttal and 0.17 for refutation.\nWe analyzed the annotations and found the following phenomena that usually caused disagreements between annotators.\nEach argument component (e.g., premise or backing) should express one consistent and coherent piece of information, for example a single reason in case of the premise (see Section UID73 ). However, the decision whether a longer text should be kept as a single argument component or segmented into multiple components is subjective and highly text-specific.\nWhile rhetorical questions have been researched extensively in linguistics BIBREF78 , BIBREF79 , BIBREF80 , BIBREF81 , their role in argumentation represents a substantial research question BIBREF82 , BIBREF83 , BIBREF84 , BIBREF85 , BIBREF86 . Teninbaum.2011 provides a brief history of rhetorical questions in persuasion. In short, rhetorical questions should provoke the reader. From the perspective of our argumentation model, rhetorical questions might fall both into the logos dimension (and thus be labeled as, e.g., claim, premise, etc.) or into the pathos dimension (refer to Section SECREF20 ). Again, the decision is usually not clear-cut.\nAs introduced in section UID55 , rebuttal attacks the claim by presenting an opponent's view. In most cases, the rebuttal is again attacked by the author using refutation. From the pragmatic perspective, refutation thus supports the author's stance expressed by the claim. Therefore, it can be easily confused with premises, as the function of both is to provide support for the claim. Refutation thus only takes place if it is meant as a reaction to the rebuttal. It follows the discussed matter and contradicts it. Such a discourse is usually expressed as:\n[claim: My claim.] [rebuttal: On the other hand, some people claim XXX which makes my claim wrong.] [refutation: But this is not true, because of YYY.]\nHowever, the author might also take the following defensible approach to formulate the argument:\n[rebuttal: Some people claim XXX-1 which makes my claim wrong.] [refutation: But this is not true, because of YYY-1.] [rebuttal: Some people claim XXX-2 which makes my claim wrong.] [refutation: But this is not true, because of YYY-2.] [claim: Therefore my claim.]\nIf this argument is formulated without stating the rebuttals, it would be equivalent to the following:\n[premise: YYY-1.] [premise: YYY-2.] [claim: Therefore my claim.]\nThis example shows that rebuttal and refutation represent a rhetorical device to produce arguments, but the distinction between refutation and premise is context-dependent and on the functional level both premise and refutation have very similar role – to support the author's standpoint. Although introducing dialogical moves into monological model and its practical consequences, as described above, can be seen as a shortcoming of our model, this rhetoric figure has been identified by argumentation researchers as procatalepsis BIBREF43 . A broader view on incorporating opposing views (or lack thereof) is discussed under the term confirmation bias by BIBREF21 who claim that “[...] people are trying to convince others. They are typically looking for arguments and evidence to confirm their own claim, and ignoring negative arguments and evidence unless they anticipate having to rebut them.” The dialectical attack of possible counter-arguments may thus strengthen one's own argument.\nOne possible solution would be to refrain from capturing this phenomena completely and to simplify the model to claims and premises, for instance. However, the following example would then miss an important piece of information, as the last two clauses would be left un-annotated. At the same time, annotating the last clause as premise would be misleading, because it does not support the claim (in fact, it supports it only indirectly by attacking the rebuttal; this can be seen as a support is considered as an admissible extension of abstract argument graph by BIBREF87 ).\nDoc#422 (forumpost, homeschooling) [claim: I try not to be anti-homeschooling, but... it's just hard for me.] [premise: I really haven't met any homeschoolers who turned out quite right, including myself.] I apologize if what I'm saying offends any of you - that's not my intention, [rebuttal: I know that there are many homeschooled children who do just fine,] but [refutation: that hasn't been my experience.]\nTo the best of our knowledge, these context-dependent dialogical properties of argument components using Toulmin's model have not been solved in the literature on argumentation theory and we suggest that these observations should be taken into account in the future research in monological argumentation.\nAppeal to emotion, sarcasm, irony, or jokes are common in argumentation in user-generated Web content. We also observed documents in our data that were purely sarcastic (the pathos dimension), therefore logical analysis of the argument (the logos dimension) would make no sense. However, given the structure of such documents, some claims or premises might be also identified. Such an argument is a typical example of fallacious argumentation, which intentionally pretends to present a valid argument, but its persuasion is conveyed purely for example by appealing to emotions of the reader BIBREF88 .\nWe present some statistics of the annotated data that are important from the argumentation research perspective. Regardless of the register, 48% of claims are implicit. This means that the authors assume that their standpoint towards the discussed controversy can be inferred by the reader and give only reasons for that standpoint. Also, explicit claims are mainly written just once, only in 3% of the documents the claim was rephrased and occurred multiple times.\nIn 6% of the documents, the reasons for an implicit claim are given only in the pathos dimension, making the argument purely persuasive without logical argumentation.\nThe “myside bias”, defined as a bias against information supporting another side of an argument BIBREF89 , BIBREF90 , can be observed by the presence of rebuttals to the author's claim or by formulating arguments for both sides when the overall stance is neutral. While 85% of the documents do not consider any opposing side, only 8% documents present a rebuttal, which is then attacked by refutation in 4% of the documents. Multiple rebuttals and refutations were found in 3% of the documents. Only 4% of the documents were overall neutral and presented arguments for both sides, mainly in blog posts.\nWe were also interested whether mitigating linguistic devices are employed in the annotated arguments, namely in their main stance-taking components, the claims. Such devices typically include parenthetical verbs, syntactic constructions, token agreements, hedges, challenge questions, discourse markers, and tag questions, among others BIBREF91 . In particular, [p. 1]Kaltenbock.et.al.2010 define hedging as a discourse strategy that reduces the force or truth of an utterance and thus reduces the risk a speaker runs when uttering a strong or firm assertion or other speech act. We manually examined the use of hedging in the annotated claims.\nOur main observation is that hedging is used differently across topics. For instance, about 30-35% of claims in homeschooling and mainstreaming signal the lack of a full commitment to the expressed stance, in contrast to prayer in schools (15%) or public vs. private schools (about 10%). Typical hedging cues include speculations and modality (“If I have kids, I will probably homeschool them.”), statements as neutral observations (“It's not wrong to hold the opinion that in general it's better for kids to go to school than to be homeschooled.”), or weasel phrases BIBREF92 (“In some cases, inclusion can work fantastically well.”, “For the majority of the children in the school, mainstream would not have been a suitable placement.”).\nOn the other hand, most claims that are used for instance in the prayer in schools arguments are very direct, without trying to diminish its commitment to the conveyed belief (for example, “NO PRAYER IN SCHOOLS!... period.”, “Get it out of public schools”, “Pray at home.”, or “No organized prayers or services anywhere on public school board property - FOR ANYONE.”). Moreover, some claims are clearly offensive, persuading by direct imperative clauses towards the opponents/audience (“TAKE YOUR KIDS PRIVATE IF YOU CARE AS I DID”, “Run, don't walk, to the nearest private school.”) or even accuse the opponents for taking a certain stance (“You are a bad person if you send your children to private school.”).\nThese observations are consistent with the findings from the first annotation study on persuasion (see section UID48 ), namely that some topics attract heated argumentation where participant take very clear and reserved standpoints (such as prayer in schools or private vs. public schools), while discussions about other topics are rather milder. It has been shown that the choices a speaker makes to express a position are informed by their social and cultural background, as well as their ability to speak the language BIBREF93 , BIBREF94 , BIBREF91 . However, given the uncontrolled settings of the user-generated Web content, we cannot infer any similar conclusions in this respect.\nWe investigated premises across all topics in order to find the type of support used in the argument. We followed the approach of Park.Cardie.2014, who distinguished three types of propositions in their study, namely unverifiable, verifiable non-experiential, and verifiable experiential.\nVerifiable non-experiential and verifiable experiential propositions, unlike unverifiable propositions, contain an objective assertion, where objective means “expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations.” Such assertions have truth values that can be proved or disproved with objective evidence; the correctness of the assertion or the availability of the objective evidence does not matter BIBREF8 . A verifiable proposition can further be distinguished as experiential or not, depending on whether the proposition is about the writer's personal state or experience or something non-experiential. Verifiable experiential propositions are sometimes referred to as anectotal evidence, provide the novel knowledge that readers are seeking BIBREF8 .\nTable TABREF97 shows the distribution of the premise types with examples for each topic from the annotated corpus. As can be seen in the first row, arguments in prayer in schools contain majority (73%) of unverifiable premises. Closer examination reveals that their content vary from general vague propositions to obvious fallacies, such as a hasty generalization, straw men, or slippery slope. As Nieminen.Mustonen.2014 found out, fallacies are very common in argumentation about religion-related issues. On the other side of the spectrum, arguments about redshirting rely mostly on anecdotal evidence (61% of verifiable experiential propositions). We will discuss the phenomena of narratives in argumentation in more detail later in section UID98 . All the topics except private vs. public schools exhibit similar amount of verifiable non-experiential premises (9%–22%), usually referring to expert studies or facts. However, this type of premises has usually the lowest frequency.\nManually analyzing argumentative discourse and reconstructing (annotating) the underlying argument structure and its components is difficult. As [p. 267]Reed2006 point out, “the analysis of arguments is often hard, not only for students, but for experts too.” According to [p. 81]Harrell.2011b, argumentation is a skill and “even for simple arguments, untrained college students can identify the conclusion but without prompting are poor at both identifying the premises and how the premises support the conclusion.” [p. 81]Harrell.2011 further claims that “a wide literature supports the contention that the particular skills of understanding, evaluating, and producing arguments are generally poor in the population of people who have not had specific training and that specific training is what improves these skills.” Some studies, for example, show that students perform significantly better on reasoning tasks when they have learned to identify premises and conclusions BIBREF95 or have learned some standard argumentation norms BIBREF96 .\nOne particular extra challenge in analyzing argumentation in Web user-generated discourse is that the authors produce their texts probably without any existing argumentation theory or model in mind. We assume that argumentation or persuasion is inherent when users discuss controversial topics, but the true reasons why people participate in on-line communities and what drives their behavior is another research question BIBREF97 , BIBREF98 , BIBREF99 , BIBREF100 . When the analyzed texts have a clear intention to produce argumentative discourse, such as in argumentative essays BIBREF7 , the argumentation is much more explicit and a substantially higher inter-annotator agreement can be achieved.\nThe model seems to be suitable for short persuasive documents, such as comments and forum posts. Its applicability to longer documents, such as articles or blog posts, is problematic for several reasons.\nThe argument components of the (modified) Toulmin's model and their roles are not expressive enough to capture argumentation that not only conveys the logical structure (in terms of reasons put forward to support the claim), but also relies heavily on the rhetorical power. This involves various stylistic devices, pervading narratives, direct and indirect speech, or interviews. While in some cases the argument components are easily recognizable, the vast majority of the discourse in articles and blog posts does not correspond to any distinguishable argumentative function in the logos dimension. As the purpose of such discourse relates more to rhetoric than to argumentation, unambiguous analysis of such phenomena goes beyond capabilities of the current argumentation model. For a discussion about metaphors in Toulmin's model of argumentation see, e.g., BIBREF102 , BIBREF103 .\nArticles without a clear standpoint towards the discussed controversy cannot be easily annotated with the model either. Although the matter is viewed from both sides and there might be reasons presented for either of them, the overall persuasive intention is missing and fitting such data to the argumentation framework causes disagreements. One solution might be to break the document down to paragraphs and annotate each paragraph separately, examining argumentation on a different level of granularity.\nAs introduced in section SECREF20 , there are several dimensions of an argument. The Toulmin's model focuses solely on the logos dimension. We decided to ignore the ethos dimension, because dealing with the author's credibility remains unclear, given the variety of the source web data. However, exploiting the pathos dimension of an argument is prevalent in the web data, for example as an appeal to emotions. Therefore we experimented with annotating appeal to emotions as a separate category independent of components in the logos dimension. We defined some features for the annotators how to distinguish appeal to emotions. Figurative language such as hyperbole, sarcasm, or obvious exaggerating to “spice up” the argument are the typical signs of pathos. In an extreme case, the whole argument might be purely emotional, as in the following example.\nDoc#1698 (comment, prayer in schools) [app-to-emot: Prayer being removed from school is just the leading indicator of a nation that is ‘Falling Away’ from Jehovah. [...] And the disasters we see today are simply God’s finger writing on the wall: Mene, mene, Tekel, Upharsin; that is, God has weighed America in the balances, and we’ve been found wanting. No wonder 50 million babies have been aborted since 1973. [...]]\nWe kept annotations on the pathos dimension as simple as possible (with only one appeal to emotions label), but the resulting agreement was unsatisfying ( INLINEFORM0 0.30) even after several annotation iterations. Appeal to emotions is considered as a type of fallacy BIBREF104 , BIBREF18 . Given the results, we assume that more carefully designed approach to fallacy annotation should be applied. To the best of our knowledge, there have been very few research works on modeling fallacies similarly to arguments on the discourse level BIBREF105 . Therefore the question, in which detail and structure fallacies should be annotated, remains open. For the rest of the paper, we thus focus on the logos dimension solely.\nSome of the educational topics under examination relate to young children (e.g., redshirting or mainstreaming); therefore we assume that the majority of participants in discussions are their parents. We observed that many documents related to these topics contain narratives. Sometimes the story telling is meant as a support for the argument, but there are documents where the narrative has no intention to persuade and is simply a story sharing.\nThere is no widely accepted theory of the role of narratives among argumentation scholars. According to Fisher.1987, humans are storytellers by nature, and the “reason” in argumentation is therefore better understood in and through the narratives. He found that good reasons often take the form of narratives. Hoeken.Fikkers.2014 investigated how integration of explicit argumentative content into narratives influences issue-relevant thinking and concluded that identifying with the character being in favor of the issue yielded a more positive attitude toward the issue. In a recent research, Bex.2011 proposes an argumentative-narrative model of reasoning with evidence, further elaborated in BIBREF106 ; also Niehaus.et.al.2012 proposes a computational model of narrative persuasion.\nStemming from another research field, LeytonEscobar2014 found that online community members who use and share narratives have higher participation levels and that narratives are useful tools to build cohesive cultures and increase participation. Betsch.et.al.2010 examined influencing vaccine intentions among parents and found that narratives carry more weight than statistics.\nWe observed no significant correlation in sentence coverage and average sentence length measures.",

        "answer": "High-quality statistical machine translation (SMT).",
        "evidence": "Princeton WordNet BIBREF0 is one of the most important resources used in many different tasks across linguistics and natural language processing, however the resource is only available for English and is limited in its coverage of real world concepts. To cross the language barrier, huge efforts have been made to extend the Princeton WordNet with multilingual information in projects, such as EuroWordNet BIBREF1 , BalkaNet BIBREF2 and MultiWordNet BIBREF3 , mostly following the extend approach, where the structure of the Princeton WordNet is preserved and only the words in each synset are translated and new synsets are added for concepts. Furthermore, the Princeton WordNet has many fewer concepts than large scale encyclopedias such as Wikipedia and resources derived from it such as DBpedia BIBREF4 and BabelNet BIBREF5 . This problem is even worse for many non-English wordnets, due to the extend approach, as these resources have even fewer synsets than Princeton WordNet. Furthermore, there are still many languages for which a wordnet does not exist or is not available to all potential users due to licensing restrictions.\nTo address these deficiencies we propose two approaches. Firstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages. While an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries. In addition, our method can handle fundamental complexities such as the need to translate all senses of a word including low-frequency senses, which is very challenging for current SMT approaches. For these reasons, we leverage existing translations of Princeton WordNet entries in other languages to identify contextual information for wordnet senses from a large set of generic parallel corpora. The goal is to identify sentences that share the same semantic information in respect to the synset of the Princeton WordNet entry that we want to translate. Secondly, we describe a novel system based on state-of-the-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia. This method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks. These statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph. These are combined using a constraint-based solver that considers not only the semantic similarity of the synsets but also the overall structure of the alignment and its consistency, following the best practices in ontology alignment.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet BIBREF6 , which is available under an open (CC-BY) license. Finally, we describe how this resource is published, firstly as linked data in the linguistic linked open data cloud, as well as published in all the formats of the Global WordNet Association Interlingual Index.\nFirstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages.",

        "question": "Does the proposed approach improve translation performance?",
        "answer": "Yes.",
        "evidence": "Neural machine translation (NMT) is popularly implemented as an encoder-decoder framework BIBREF0, in which the encoder is right in charge of source sentence representation. Typically, the input sentence is implicitly represented as a contextualized source representation through deep learning networks. By further feeding the decoder, the source representation is used to learn dependent time-step context vectors for predicting target translation BIBREF1.\nIn state-of-the-art Transformer-based encoder, self-attention mechanisms are good at capturing the general information in a sentence BIBREF2, BIBREF3, BIBREF4. However, it is difficult to distinguish which kind of information lying deeply under the language is really salient for learning source representation. Intuitively, when a person reads a source sentence, he/she often selectively focuses on the basic sentence meaning, and re-reads the entire sentence to understand its meaning completely. Take the English sentence in Table TABREF2 as an example. We manually annotate its basic meaning as a shorter sequence of words than in the original sentence, called backbone information. Obviously, these words with the basic meaning contain more important information for human understanding than the remaining words in the sentence. We argue that such backbone information is also helpful for learning source representation, and is not explicitly considered by the existing NMT system to enrich the source sentence representation.\nIn this paper, we propose a novel explicit sentence compression approach to enhance the source representation for NMT. To this end, we first design three sentence compression models to accommodate the needs of various languages and scenarios, including supervised, unsupervised, and semi-supervised ways, to learn a backbone information words sequence (as shown in Table TABREF2) from the source sentence. We then propose three translation models, including backbone source-side fusion based NMT (BSFNMT), backbone target-side fusion (BTFNMT), and both-side fusion based NMT (BBFNMT), to introduce this backbone knowledge into the existing Transformer NMT system for improving translation predictions. Empirical results on the WMT14 English-to-German and English-to-French translation tasks show that the proposed approach significantly improves the translation performance over the strong even state-of-the-art NMT baselines.\nEmpirical results on the WMT14 English-to-German and English-to-French translation tasks show that the proposed approach significantly improves the translation performance over the strong even state-of-the-art NMT baselines.",

        "answer": "To ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning.",
        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nWe introduce the Transformer encoder in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning",

        "evidence": "Reliable counts of speakers of Louisiana French are difficult to obtain as distinct from other varieties of French. However, the vast majority of native residents of Louisiana and east and southeast Texas who speak French are likely speakers of Louisiana French.\n\nIn Louisiana, as of 2010, the population of French speakers was approximately 115,183. These populations were concentrated most heavily in the southern, coastal parishes.\n\nIn Texas, as of 2010, the French-speaking population was 55,773, though many of these were likely immigrants from France and other locations, living in the urban areas. Nevertheless, in the rural eastern/southeastern Texas counties of Orange, Jefferson, Chambers, Newton, Jasper, Tyler, Liberty, and Hardin alone—areas where it can be reasonably presumed that almost all French speakers are Louisiana French speakers—the total French-speaking population was composed of 3,400 individuals. It is likely a substantial portion of the 14,493 speakers in Houston's Harris county are also Louisiana French speakers.

        "question": "What is a quantum computer?",
        "evidence": "",
        "answer": "A quantum computer is a computer that exploits quantum mechanical phenomena. At small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware. Classical physics cannot explain the operation of these quantum devices, and a scalable quantum computer could perform some calculations exponentially faster than any modern \"classical\" computer. In particular, a large-scale quantum computer could break widely used encryption schemes and aid physicists in performing physical simulations; however, the current state of the art is still largely experimental and impractical.\n\nThe basic unit of information in quantum computing is the qubit, similar to the bit in traditional digital electronics. Unlike a classical bit, a qubit can exist in a superposition of its two \"basis\" states, which loosely means that it is in both states simultaneously. When measuring a qubit, the result is a probabilistic output of a classical bit. If a quantum computer manipulates the qubit in a particular way, wave interference effects can amplify the desired measurement results. The design of quantum algorithms involves creating procedures that allow a quantum computer to perform calculations efficiently.\n\nPhysically engineering high-quality qubits has proven challenging. If a physical qubit is not sufficiently isolated from its environment, it suffers from quantum decoherence, introducing noise into calculations. National governments have invested heavily in experimental research that aims to develop scalable qubits with longer coherence times and lower error rates. Two of the most promising technologies are superconductors (which isolate an electrical current by eliminating electrical resistance) and ion traps (which confine a single atomic particle using electromagnetic fields).\n\nAny computational problem that can be solved by a classical computer can also be solved by a quantum computer. Conversely, any problem that can be solved by a quantum computer can also be solved by a classical computer, at least in principle given enough time. In other words, quantum computers obey the Church–Turing thesis. This means that while quantum computers provide no additional advantages over classical computers in terms of computability, quantum algorithms for certain problems have significantly lower time complexities than corresponding known classical algorithms. Notably, quantum computers are believed to be able to solve certain problems quickly that no classical computer could solve in any feasible amount of time—a feat known as \"quantum supremacy.\" The study of the computational complexity of problems with respect to quantum computers is known as quantum complexity theory.",

        "evidence": "Adversarial examples are generally minimal perturbations applied to the input data in an effort to expose the regions of the input space where a trained model performs poorly. Prior works BIBREF0, BIBREF1 have demonstrated the ability of an adversary to evade state-of-the-art classifiers by carefully crafting attack examples which can be even imperceptible to humans. Following such approaches, there has been a number of techniques aimed at generating adversarial examples BIBREF2, BIBREF3. Depending on the degree of access to the target model, an adversary may operate in one of the two different settings: (a) black-box setting, where an adversary doesn't have access to target model's internal architecture or its parameters, (b) white-box setting, where an adversary has access to the target model, its parameters, and input feature representations. In both these settings, the adversary cannot alter the training data or the target model itself. Depending on the purpose of the adversary, adversarial attacks can be categorized as (a) targeted attack and (b) non-targeted attack. In a targeted attack, the output category of a generated example is intentionally controlled to a specific target category with limited change in semantic information. While a non-targeted attack doesn't care about the category of misclassified results.\nMost of the prior work has focused on image classification models where adversarial examples are obtained by introducing imperceptible changes to pixel values through optimization techniques BIBREF4, BIBREF5. However, generating natural language adversarial examples can be challenging mainly due to the discrete nature of text samples. Continuous data like image or speech is much more tolerant to perturbations compared to text BIBREF6. In textual domain, even a small perturbation is clearly perceptible and can completely change the semantics of the text. Another challenge for generating adversarial examples relates to identifying salient areas of the text where a perturbation can be applied successfully to fool the target classifier. In addition to fooling the target classifier, the adversary is designed with different constraints depending on the task and its motivations BIBREF7. In our work, we focus on constraining our adversary to craft examples with semantic preservation and minimum perturbations to the input text.\nGiven different settings of the adversary, there are other works that have designed attacks in “gray-box” settings BIBREF8, BIBREF9, BIBREF10. However, the definitions of “gray-box” attacks are quite different in each of these approaches. In this paper, we focus on “black-box” setting where we assume that the adversary possesses a limited set of labeled data, which is different from the target's training data, and also has an oracle access to the system, i.e., one can query the target classifier with any input and get its corresponding predictions. We propose an effective technique to generate adversarial examples in a black-box setting. We develop an Adversarial Example Generator (AEG) model that uses a reinforcement learning framing to generate adversarial examples. We evaluate our models using a word-based BIBREF11 and character-based BIBREF12 text classification model on benchmark classification tasks: sentiment classification and news categorization. The adversarial sequences generated are able to effectively fool the classifiers without changing the semantics of the text. Our contributions are as follows:\nWe propose a black-box non-targeted attack strategy by combining ideas of substitute network and adversarial example generation. We formulate it as a reinforcement learning task.\nWe introduce an encoder-decoder that operates over words and characters of an input text and empowers the model to introduce word and character-level perturbations.\nWe adopt a self-critical sequence training technique to train our model to generate examples that can fool or increase the probability of misclassification in text classifiers.\nWe evaluate our models on two different datasets associated with two different tasks: IMDB sentiment classification and AG's news categorization task. We run ablation studies on various components of the model and provide insights into decisions of our model.\nWe propose a black-box non-targeted attack strategy by combining ideas of substitute network and adversarial example generation.

        "evidence": "Named Entity Recognition (NER) in the Biomedical domain usually includes recognition of entities such as proteins, genes, diseases, treatments, drugs, etc. Fact extraction involves extraction of Named Entities from a corpus, usually given a certain ontology. When compared to NER in the domain of general text, the biomedical domain has some characteristic challenges:\nSome of the earliest systems were heavily dependent on hand-crafted features. The method proposed in BIBREF4 for recognition of protein names in text does not require any prepared dictionary. The work gives examples of diversity in protein names and lists multiple rules depending on simple word features as well as POS tags.\n BIBREF5 adopt a machine learning approach for NER. Their NER system extracts medical problems, tests and treatments from discharge summaries and progress notes. They use a semi-Conditional Random Field (semi-CRF) BIBREF6 to output labels over all tokens in the sentence. They use a variety of token, context and sentence level features. They also use some concept mapping features using existing annotation tools, as well as Brown clustering to form 128 clusters over the unlabelled data. The dataset used is the i2b2 2010 challenge dataset. Their system achieves an F-Score of 0.85. BIBREF7 is an incremental paper on NER taggers. It uses 3 types of word-representation techniques (Brown clustering, distributional clustering, word vectors) to improve performance of the NER Conditional Random Field tagger, and achieves marginal F-Score improvements.\n BIBREF8 propose a boostrapping mechanism to bootstrap biomedical ontologies using NELL BIBREF9 , which uses a coupled semi-supervised bootstrapping approach to extract facts from text, given an ontology and a small number of “seed” examples for each category. This interesting approach (called BioNELL) uses an ontology of over 100 categories. In contrast to NELL, BioNELL does not contain any relations in the ontology. BioNELL is motivated by the fact that a lot of scientific literature available online is highly reliable due to peer-review. The authors note that the algorithm used by NELL to bootstrap fails in BioNELL due to ambiguities in biomedical literature, and heavy semantic drift. One of the causes for this is that often common words such as “white”, “dad”, “arm” are used as names of genes- this can easily result in semantic drift in one iteration of the bootstrapping. In order to mitigate this, they use Pointwise Mutual Information scores for corpus level statistics, which attributes a small score to common words. In addition, in contrast to NELL, BioNELL only uses high instances as seeds in the next iteration, but adds low ranking instances to the knowledge base. Since evaluation is not possible using Mechanical Turk or a small number of experts (due to the complexity of the task), they use Freebase BIBREF10 , a knowledge base that has some biomedical concepts as well. The lexicon learned using BioNELL is used to train an NER system. The system shows a very high precision, thereby showing that BioNELL learns very few ambiguous terms.\nMore recently, deep learning techniques have been developed to further enhance the performance of NER systems. BIBREF11 explore recurrent neural networks for the problem of NER in biomedical text.\nWhen compared to NER in the domain of general text, the biomedical domain has some characteristic challenges: 1. Synonymy: the same biomedical entity is often known by different names. E.g. “cyclin-dependent kinase inhibitor p27” and “p27kip1” are the same proteins, “heart attack” and “myocardial infarcation” refer to the same medical problem. 2. Abbreviations: The literature is rich with ambiguous abbreviations: “RA” can refer to “right atrium”, “rheumatoid arthritis”, “renal artery” or several other concepts (Pakhomov, 2002) 3.

        "question": "Is the LMs lag behind human performance?",
        "answer": "Yes, it is.",
        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nWe find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.",

        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nFor one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well.

        "evidence": "With the availability of rich data on users' locations, profiles and search history, personalization has become the leading trend in large-scale information retrieval. However, efficiency through personalization is not yet the most suitable model when tackling domain-specific searches. This is due to several factors, such as the lexical and semantic challenges of domain-specific data that often include advanced argumentation and complex contextual information, the higher sparseness of relevant information sources, and the more pronounced lack of similarities between users' searches.\nA recent study on expert search strategies among healthcare information professionals BIBREF0 showed that, for a given search task, they spend an average of 60 minutes per collection or database, 3 minutes to examine the relevance of each document, and 4 hours of total search time. When written in steps, their search strategy spans over 15 lines and can reach up to 105 lines.\nWith the abundance of information sources in the medical domain, consumers are more and more faced with a similar challenge, one that needs dedicated solutions that can adapt to the heterogeneity and specifics of health-related information.\nDedicated Question Answering (QA) systems are one of the viable solutions to this problem as they are designed to understand natural language questions without relying on external information on the users.\nIn the context of QA, the goal of Recognizing Question Entailment (RQE) is to retrieve answers to a premise question ( INLINEFORM0 ) by retrieving inferred or entailed questions, called hypothesis questions ( INLINEFORM1 ) that already have associated answers. Therefore, we define the entailment relation between two questions as: a question INLINEFORM2 entails a question INLINEFORM3 if every answer to INLINEFORM4 is also a correct answer to INLINEFORM5 BIBREF1 .\nRQE is particularly relevant due to the increasing numbers of similar questions posted online BIBREF2 and its ability to solve differently the challenging issues of question understanding and answer extraction. In addition to being used to find relevant answers, these resources can also be used in training models able to recognize inference relations and similarity between questions.\nQuestion similarity has recently attracted international challenges BIBREF3 , BIBREF4 and several research efforts proposing a wide range of approaches, including Logistic Regression, Recurrent Neural Networks (RNNs), Long Short Term Memory cells (LSTMs), and Convolutional Neural Networks (CNNs) BIBREF5 , BIBREF6 , BIBREF1 , BIBREF7 .\nIn this paper, we study question entailment in the medical domain and the effectiveness of the end-to-end RQE-based QA approach by evaluating the relevance of the retrieved answers.

        "question": "Provide a bulleted summary of the different types of taxes in the USA.",
        "evidence": "The United States of America has separate federal, state, and local governments with taxes imposed at each of these levels. Taxes are levied on income, payroll, property, sales, capital gains, dividends, imports, estates and gifts, as well as various fees. In 2020, taxes collected by federal, state, and local governments amounted to 25.5% of GDP, below the OECD average of 33.5% of GDP. The United States had the seventh-lowest tax revenue-to-GDP ratio among OECD countries in 2020, with a higher ratio than Mexico, Colombia, Chile, Ireland, Costa Rica, and Turkey.\n\nTaxes fall much more heavily on labor income than on capital income. Divergent taxes and subsidies for different forms of income and spending can also constitute a form of indirect taxation of some activities over others. For example, individual spending on higher education can be said to be \"taxed\" at a high rate, compared to other forms of personal expenditure which are formally recognized as investments.\n\nTaxes are imposed on net income of individuals and corporations by the federal, most state, and some local governments. Citizens and residents are taxed on worldwide income and allowed a credit for foreign taxes. Income subject to tax is determined under tax accounting rules, not financial accounting principles, and includes almost all income from whatever source. Most business expenses reduce taxable income, though limits apply to a few expenses. Individuals are permitted to reduce taxable income by personal allowances and certain non-business expenses, including home mortgage interest, state and local taxes, charitable contributions, and medical and certain other expenses incurred above certain percentages of income. State rules for determining taxable income often differ from federal rules. Federal marginal tax rates vary from 10% to 37% of taxable income. State and local tax rates vary widely by jurisdiction, from 0% to 13.30% of income, and many are graduated. State taxes are generally treated as a deductible expense for federal tax computation, although the 2017 tax law imposed a $10,000 limit on the state and local tax (\"SALT\") deduction, which raised the effective tax rate on medium and high earners in high tax states. Prior to the SALT deduction limit, the average deduction exceeded $10,000 in most of the Midwest, and exceeded $11,000 in most of the Northeastern United States, as well as California and Oregon. The states impacted the most by the limit were the tri-state area (NY, NJ, and CT) and California; the average SALT deduction in those states was greater than $17,000 in 2014.\n\nThe United States is one of two countries in the world that taxes its non-resident citizens on worldwide income, in the same manner and rates as residents; the other is Eritrea. The U.S. Supreme Court upheld the constitutionality of imposition of such a tax in the case of Cook v. Tait. Nonetheless, the foreign earned income exclusion eliminates U.S. taxes on the first $108,700 of annual foreign income earned by U.S. citizens living and working abroad.\n\nPayroll taxes are imposed by the federal and all state governments. These include Social Security and Medicare taxes imposed on both employers and employees, at a combined rate of 15.3% (13.3% for 2011 and 2012). Social Security tax applies only to the first $132,900 of wages in 2019. There is an additional Medicare tax of 0.9% on wages above $200,000. Employers must withhold income taxes on wages. An unemployment tax and certain other levies apply to employers. Payroll taxes have dramatically increased as a share of federal revenue since the 1950s, while corporate income taxes have fallen as a share of revenue. (Corporate profits have not fallen as a share of GDP).\n\nProperty taxes are imposed by most local governments and many special purpose authorities based on the fair market value of property. School and other authorities are often separately governed, and impose separate taxes. Property tax is generally imposed only on realty, though some jurisdictions tax some forms of business property. Property tax rules and rates vary widely with annual median rates ranging from 0.2% to 1.9% of a property's value depending on the state.\n\nSales taxes are imposed by most states and some localities on the price at retail sale of many goods and some services. Sales tax rates vary widely among jurisdictions, from 0% to 16%, and may vary within a jurisdiction based on the particular goods or services taxed. Sales tax is collected by the seller at the time of sale, or remitted as use tax by buyers of taxable items who did not pay sales tax.\n\nThe United States imposes tariffs or customs duties on the import of many types of goods from many jurisdictions. These tariffs or duties must be paid before the goods can be legally imported. Rates of duty vary from 0% to more than 20%, based on the particular goods and country of origin.\n\nEstate and gift taxes are imposed by the federal and some state governments on the transfer of property inheritance, by will, or by lifetime donation. Similar to federal income taxes, federal estate and gift taxes are imposed on worldwide property of citizens and residents and allow a credit for foreign taxes.",
        "answer": "The following are the different types of taxes in the USA:\n- Income Tax: Imposed on income from any source\n- Payroll Tax: Social Security and Medicare taxes imposed on both employers and employees\n- Property Tax: Imposed on value of property\n- Sales Tax: Imposed on the price at retail sale of goods and services",

The same coefficient for all the methods leads to a fair comparison, because different regularization coefficients lead to different objectives, which makes different methods incomparable. We have added this explanation in the last paragraph of Section 4.1.",

The dimensions of mnist and usps are 780 and 256, respectively. We used cifar10 and SARS-CoV-2 (S-CoV) as the image data. S-CoV contains RGB CT scans and is used to identify whether the patient is infected by the virus. Each image in the two data sets was first reshaped into 32 × 32 image and then normalized according to the mean and variance sampled, respectively. We used IMDb and COVID-19-tweets (COV-tw) as the text data. COV-tw collects the English Tweets about COVID-19 and is labeled as informative or not. We took 20% of the training data to serve as the validation set except for COV-tw. In COV-tw, 1000 validation instances are provided. On tabular data, our method was evaluated using a simple two-linear-layer neural network which has 100 neurons in each hidden layer. For image classification, our method was tested on the ResNet-18 network. To solve text classification problems, we used an LSTM network with pre-trained word vectors. Baselines: Our method was compared with the widely used L-BFGS and Equilibrated SGD (ESGD) optimization methods which both use the second-order information in training. ESGD adopts an equilibration preconditioner to reduce the condition number and escape saddle points. We used the implementation of ESGD published by.\nThe experiments were conducted on a machine with an Intel(R) Xeon(R) Silver 4210 CPU of 126 GB memory and two GeForce RTX 3090 GPUs running on a Linux OS. All the methods including the baselines and our method were implemented using PyTorch. The size of history used in L-BFGS was set as 3 for limited memory. The mini-batch size was set to 64. L 2 regularization was used with its coefficient set to 10 −4 following the setting in the studies. The same regularization coefficient for all the methods leads to a fair comparison. In Kernel SGD, to compute the kernel matrix, we used the radial basis function kernel (i.e., k(x i , x j ) = exp(−γ||x i − x j || 2 2 )). Through the whole experiment, the learning rate and the hyper-parameter γ for the kernel were selected from {0.1, 0.01, 0.001, 0.0001}. We terminated the training when the convergence conditions were satisfied, i.e., the change of loss is less than 1 × 10 −4 in 3 consecutive epochs or the training reaches 500 epochs. We repeated each experiment five times to acquire average performance.\nL2 regularization was used with its coefficient set to 10−4 following the setting in the studies (He et al., 2016; Huang et al., 2017).

Also, typically the team has to move the ball 75 to 80 yards to the end zone. Only a few strong armed quarterbacks can throw that far. Even fewer can do it under pressure. The other main issue is that there is a very low chance of completing the pass. \n\nSo, smart teams and coaches, use a variety of strategies of both throwing the ball different distances, running the ball, and based on distance, kicking field goals.

In general, calculus techniques mean to use objective and constraint information at a particular point x, to deduce information about the behaviour of the objective function at all surrounding points close to x. The deduced information is then used to guide the search direction. In contrast, combinatorial optimisation problems are to some extent harder to solve than continuous ones. This is because the behaviour of the objective and constraints may change significantly as we move from one feasible point to another, even if the two points are close according to some measure.

Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nThe frame-semantic parser is built based on FrameNet and BabelNet where FrameNet is used to capture the meaning of the sentence and BabelNet is used to disambiguate the meaning of the extracted entities from the sentence.",

        "evidence": "We use bootstrap sampling (500 iterations) over the 1100 tables for which we collected human annotations to get an idea of how the correlation of each metric varies with the underlying data. In each iteration, we sample with replacement, tables along with their references and all the generated texts for that table. Then we compute aggregated human evaluation and metric scores for each of the models and compute the correlation between the two. We report the average correlation across all bootstrap samples for each metric in Table TABREF37 . The distribution of correlations for the best performing metrics are shown in Figure FIGREF38 .\nTable TABREF37 also indicates whether PARENT is significantly better than a baseline metric. BIBREF21 suggest using the William's test for this purpose, but since we are computing correlations between only 4/13 systems at a time, this test has very weak power in our case. Hence, we use the bootstrap samples to obtain a INLINEFORM0 confidence interval of the difference in correlation between PARENT and any other metric and check whether this is above 0 BIBREF27 .\nCorrelations are higher for the systems category than the hyperparams category. The latter is a more difficult setting since very similar models are compared, and hence the variance of the correlations is also high. Commonly used metrics which only rely on the reference (BLEU, ROUGE, METEOR, CIDEr) have only weak correlations with human judgments. In the hyperparams category, these are often negative, implying that tuning models based on these may lead to selecting worse models. BLEU performs the best among these, and adding n-grams from the table as references improves this further (BLEU-T).\nAmong the extractive evaluation metrics, CS, which also only relies on the reference, has poor correlation in the hyperparams category. RG-F, and both variants of the PARENT metric achieve the highest correlation for both settings. There is no significant difference among these for the hyperparams category, but for systems, PARENT-W is significantly better than the other two. While RG-F needs a full information extraction pipeline in its implementation, PARENT-C only relies on co-occurrence counts, and PARENT-W can be used out-of-the-box for any dataset. To our knowledge, this is the first rigorous evaluation of using information extraction for generation evaluation.\nOn this dataset, the word-overlap model showed higher correlation than the co-occurrence model for entailment. In § SECREF47 we will show that for the WebNLG dataset, where more paraphrasing is involved between the table and text, the opposite is true. Lastly, we note that the heuristic for selecting INLINEFORM0 is sufficient to produce high correlations for PARENT, however, if human annotations are available, this can be tuned to produce significantly higher correlations (PARENT*-W/C).\nCorrelations are higher for the systems cate_x0002_gory than the hyperparams category.

We reported results on this “baseline” representation in Fig 4 (c) and (d). Additionally, we considered different options for other steps of our proposed methodology beyond the graph construction (e.g., different signature constructions, classification vs. regression) and discussed our observations. Finally, we compared the efficiency of our approach to the “early stopping method”.",
        "evidence": "Task setup. We cast the NN performance prediction as a classification task. Specifically, the generated time-evolving graphs are labeled as high and low accuracy based on the performance of their corresponding NNs; Table lists the threshold value chosen for low and high accuracy labels based on the final accuracy range of trained NNs, as well as the early stopping epochs for each architecture. Five-fold cross validation is used to predict the label of the test graphs in a binary classification task using SVM and MLP, where the input is the set of temporal signatures {s t tr1 , s t tr2 , ..., s t trn }. We report the classification accuracy. Since the sample of NNs (App. A.1) is randomly selected with balanced high/low accuracy instances, the accuracy of a random classifier as the baseline is 50% (omitted from the charts to avoid clutter). Additionally, to show that our proposed graph representation and signatures are general and can be useful across different NN architectures, we consider the following setup: we train the classifier on a small set of NN models (i.e., different architectures-such as LeNet, AlexNet, and VGG-and hyperparameters), and predict the performance on unseen architectures (e.g., ResNet). We describe these experiments in App. A.4.\nResults. Figure illustrates the performance of SVM and MLP classifiers operating on weighted degree-based signatures of the rolled and unrolled graph representations of the LeNet and AlexNet architectures, trained on the CIFAR-10 dataset. We omit the results on VGG and ResNet, as well as image classification on ImageNet, because the unrolled graph generation process is prohibitively expensive, both in terms of time and space. Overall, the rolled and unrolled graph representations show similar trends in classifying NNs by effectively capturing their early training dynamics: the structural changes in the training NN architectures during the first 6-15 iterations are sufficient to classify the performance of NN instances with over 90% accuracy. However, as we discuss in § 4.3, our proposed rolled representation is significantly more efficient than the unrolled representation, and can generalize to deeper and larger NNs. We provide more details for these experiments in App. A.2. OBSERVATION 1 Both the rolled and unrolled time-evolving graph representations of NNs are effective in capturing the changes in the NN dynamics during the training phase, and can be used to predict the accuracy of an NN instance after observing only a few training epochs. Our proposed rolled representation is also space-and time-efficient, unlike the unrolled representation.\nIn the remainder of this analysis, we focus on the rolled representation, which is more efficient for larger NN models and datasets. We present the classification results for both types of signatures for the temporal graphs corresponding to the training dynamics of VGG and ResNet-44 (CIFAR-10 dataset) in Fig.(e)-(h) and LeNet, AlexNet and ResNet-50 (ImageNet datatset) in Fig.. In addition to the results discussed above for LeNet and AlexNet, we provide the NN classification accuracy for the eigenvector-based signatures in Fig. in the appendix. In all the cases, classification accuracy of 80-95% is achieved in less than 10 training epochs. For degree-based signatures, SVM tends to outperform MLP, while the trend is reversed for eigenvector-based signatures. For example, for both VGG and AlexNet for the CIFAR-10 image classification task, MLP can predict the performance with accuracy ∼95% using the eigenvector-based signatures from the first 6 training epochs; the same trend is observed on ImageNet for the LeNet and AlexNet architectures. For ResNet on the ImageNet classification task, SVM tends to perform well for both degree and eigenvector centrality signature vectors; while MLP tends to perform poorly in this case, the MLP variant operating on the exponential average of signature vectors outperforms the original MLP and all SVM variants. In all the cases, both classifiers reach performance over 80%-90% significantly before the early stopping point for all the architectures. In general, for ImageNet, we observe that the signatures based on eigenvector centrality are more effective in the NN performance prediction task compared to the weighted degree-based signatures-irrespective of NN architecture.\nOBSERVATION 2 For the CIFAR-10 image classification task, the rolled graph representation for all NN architectures and both signature types achieve accuracy of >90%. For ImageNet, the eigenvector centrality-based signatures tend to yield higher performance compared to the weighted degree-based signatures, though both achieve accuracy of 80-90%.\nResults. Figure 4 illustrates the performance of SVM and MLP classifiers operating on weighted\ndegree-based signatures of the rolled and unrolled graph representations of the LeNet and AlexNet\narchitectures, trained on the CIFAR-10 dataset.

        "question": "What kind of framework do they propose??",
        "answer": "A novel Selective Gate (SeG) framework for distantly supervised relation extraction.",
        "evidence": "Relation extraction (RE) is one of the most fundamental tasks in natural language processing, and its goal is to identify the relationship between a given pair of entities in a sentence. Typically, a large-scale training dataset with clean labels is required to train a reliable relation extraction model. However, it is time-consuming and labor-intensive to annotate such data by crowdsourcing. To overcome the lack of labeled training data, BIBREF0 mintz2009distant presents a distant supervision approach that automatically generates a large-scale, labeled training set by aligning entities in knowledge graph (e.g. Freebase BIBREF1) to corresponding entity mentions in natural language sentences. This approach is based on a strong assumption that, any sentence containing two entities should be labeled according to the relationship of the two entities on the given knowledge graph. However, this assumption does not always hold. Sometimes the same two entities in different sentences with various contexts cannot express a consistent relationship as described in the knowledge graph, which certainly results in wrongly labeled problem.\nTo alleviate the aformentioned problem, BIBREF2 riedel2010modeling proposes a multi-instance learning framework, which relaxes the strong assumption to expressed-at-least-one assumption. In plainer terms, this means any possible relation between two entities hold true in at least one distantly-labeled sentence rather than all of the them that contains those two entities. In particular, instead of generating a sentence-level label, this framework assigns a label to a bag of sentences containing a common entity pair, and the label is a relationship of the entity pair on knowledge graph. Recently, based on the labeled data at bag level, a line of works BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 under selective attention framework BIBREF5 let model implicitly focus on the correctly labeled sentence(s) by an attention mechanism and thus learn a stable and robust model from the noisy data.\nHowever, such selective attention framework is vulnerable to situations where a bag is merely comprised of one single sentence labeled; and what is worse, the only one sentence possibly expresses inconsistent relation information with the bag-level label. This scenario is not uncommon. For a popular distantly supervised relation extraction benchmark, e.g., NYT dataset BIBREF2, up to $80\\%$ of its training examples (i.e., bags) are one-sentence bags. From our data inspection, we randomly sample 100 one-sentence bags and find $35\\%$ of them is incorrectly labeled. Two examples of one-sentence bag are shown in Table TABREF1. These results indicate that, in training phrase the selective attention module is enforced to output a single-valued scalar for $80\\%$ examples, leading to an ill-trained attention module and thus hurting the performance.\nMotivated by aforementioned observations, in this paper, we propose a novel Selective Gate (SeG) framework for distantly supervised relation extraction. In the proposed framework, 1) we employ both the entity embeddings and relative position embeddings BIBREF8 for relation extraction, and an entity-aware embedding approach is proposed to dynamically integrate entity information into each word embedding, yielding more expressively-powerful representations for downstream modules; 2) to strengthen the capability of widely-used piecewise CNN (PCNN) BIBREF3 on capturing long-term dependency BIBREF9, we develop a light-weight self-attention BIBREF10, BIBREF11 mechanism to capture rich dependency information and consequently enhance the capability of neural network via producing complementary representation for PCNN; and 3) based on preceding versatile features, we design a selective gate to aggregate sentence-level representations into bag-level one and alleviate intrinsic issues appearing in selective attention.\nCompared to the baseline framework (i.e., selective attention for multi-instance learning), SeG is able to produce entity-aware embeddings and rich-contextual representations to facilitate downstream aggregation modules that stably learn from noisy training data. Moreover, SeG uses gate mechanism with pooling to overcome problem occurring in selective attention, which is caused by one-sentence bags. In addition, it still keeps a light-weight structure to ensure the scalability of this model.\nThe experiments and extensive ablation studies on New York Time dataset BIBREF2 show that our proposed framework achieves a new state-of-the-art performance regarding both AUC and top-n precision metrics for distantly supervised relation extraction task, and also verify the significance of each proposed module. Particularly, the proposed framework can achieve AUC of 0.51, which outperforms selective attention baseline by 0.14 and improves previous state-of-the-art approach by 0.09.\nMotivated by aforementioned observations, in this paper, we propose a novel Selective Gate (SeG) framework for distantly supervised relation extraction.",

To eat crawfish, sometimes called crawdads or mudbugs, you first need to purchase them.  Crawfish are usually sold by the sack with typical weights around 30-40 pounds.  You must then clean the crawfish as their natural habitats are within mud, swamps, and muck.   Rinsing them thoroughly in water is required.  Many will do this a sack at a time and continue to rinse until the water is crystal clear noting that they're clean.  Others go a step further through a process of purging.  This is using salt to have the crawfish clean out its insides.  Many think purging is a myth and simply skip this step.  Once clean, you'll want to bring a large pot (typically 80+ quarts in size) of water to a rolling boil.  Add in spices to flavor the water.  There are also pre-made bags of spice known as 'boil.'  Boil the crawfish until they float to the top and turn bright red.  Then allow the crawfish to soak to absorb the added spice.  This process can last as long as an hour or more, though 30 minutes is fairly typical.  Many people will add potatoes, corn, onions, and other sides to their boil.  Learning to peel a crawfish is an art, but can be quickly done by twisting off the tail.  Peel the rest of the shell off and eat the tail.  Many will also suck the head to get a burst of flavor.",

Hence, as the initial effort to investigate the imbalanced adversarial training problem, we start our study from the reweighting strategy and leave other methods as future work.\n[1] Lin, Tsung-Yi, et al. \"Focal loss for dense object detection.\" Proceedings of the IEEE international conference on computer vision. 2017.\n[2] Cao, Kaidi, et al. \"Learning imbalanced datasets with label-distribution-aware margin loss.\" arXiv preprint arXiv:1906.07413 (2019).",
        "evidence": "Adversarial Robustness. The vulnerability of DNN models to adversarial examples has been verified by many existing successful attack methods. To improve model robustness against adversarial attacks, various defense methods have been proposed. Among them, adversarial training has been proven to be one of the most effective defense methods. Adversarial training can be formulated as solving a min-max optimization problem where the outer minimization process enforces the model to be robust to adversarial examples, generated by the inner maximization process via some existing attacking methods like PGD.\nBased on adversarial training, several variants, such as TRADES, MART, have been presented to improve the model's performance further. More details about adversarial robustness can be found in recent surveys.\nSince almost all studies of adversarial training are focused on balanced datasets, it's worthwhile to investigate the performance of adversarial training methods on imbalanced training datasets.\nImbalanced Learning. Most existing works of imbalanced training can be roughly classified into two categories, i.e., re-sampling and reweighting. Re-sampling methods aim to reduce imbalance level through either over-sampling examples from under-represented classes or under-sampling examples from well-represented classes. reweighting methods allocate different weights for different classes or even different examples. For example, Focal loss enlarges the weights of wrongly-classified examples while reducing the weights of well-classified examples in the standard cross entropy loss; and LDAM loss regularizes the underrepresented classes more strongly than the well-represented classes to attain good generalization on under-represented classes. More details about imbalanced learning can be found in recent surveys. The majority of existing methods focused on the nature training scenario and their trained models will be crashed when facing adversarial attacks. Hence, in this paper, we develop a novel method that can defend adversarial attacks and achieve well-pleasing performance under imbalance settings.\nImbalanced Learning.

On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs). As baselines, we compare with feature spaces comprising of char n-grams BIBREF0 , TF-IDF vectors, and Bag of Words vectors (BoWV).\nMain contributions of our paper are as follows: (1) We investigate the application of deep learning methods for the task of hate speech detection.

Data can be generated from various sources and this raw data may be structured, semi structured or even unstructured. To make sense of this data, data has to be ingested and transformed. This is when data engineering comes into picture. Data engineering includes the process of extracting the raw data, ingesting data into a system like a data lake, transforming the data for business needs and finally loading it into a table. This is commonly known as ELT (Extract-Load-Transform). ETL (Extract-Transform-Load) is also possible where transformation happens before the loading stage.\nData Science and Analytics is the next step in the data lifecycle. Once the data needed for specific business need is available, data scientists use this data to run machine learning models to find the most accurate model. This data is available to the data scientists in the form of tables.

        "evidence": "Datasets and Models We evaluate our adversarial attacks on different text classification datasets from tasks such as sentiment classification, subjectivity detection and question type classification. Amazon, Yelp, IMDB are sentence-level sentiment classification datasets which have been used in recent work BIBREF15 while MR BIBREF16 contains movie reviews based on sentiment polarity. MPQA BIBREF17 is a dataset for opinion polarity detection, Subj BIBREF18 for classifying a sentence as subjective or objective and TREC BIBREF19 is a dataset for question type classification.\nWe use 3 popular text classification models: word-LSTM BIBREF20, word-CNN BIBREF21 and a fine-tuned BERT BIBREF12 base-uncased classifier. For each dataset we train the model on the training data and perform the adversarial attack on the test data. For complete model details refer to Appendix.\nAs a baseline, we consider TextFooler BIBREF11 which performs synonym replacement using a fixed word embedding space BIBREF22. We only consider the top $K{=}50$ synonyms from the MLM predictions and set a threshold of 0.8 for the cosine similarity between USE based embeddings of the adversarial and input text.\nResults We perform the 4 modes of our attack and summarize the results in Table . Across datasets and models, our BAE attacks are almost always more effective than the baseline attack, achieving significant drops of 40-80% in test accuracies, with higher average semantic similarities as shown in parentheses. BAE-R+I is the strongest attack since it allows both replacement and insertion at the same token position, with just one exception. We observe a general trend that the BAE-R and BAE-I attacks often perform comparably, while the BAE-R/I and BAE-R+I attacks are much stronger. We observe that the BERT-based classifier is more robust to the BAE and TextFooler attacks than the word-LSTM and word-CNN models which can be attributed to its large size and pre-training on a large corpus.\nThe baseline attack is often stronger than the BAE-R and BAE-I attacks for the BERT based classifier. We attribute this to the shared parameter space between the BERT-MLM and the BERT classifier before fine-tuning. The predicted tokens from BERT-MLM may not drastically change the internal representations learned by the BERT classifier, hindering their ability to adversarially affect the classifier prediction.\nEffectiveness We study the effectiveness of BAE on limiting the number of R/I operations permitted on the original text. We plot the attack performance as a function of maximum $\\%$ perturbation (ratio of number of word replacements and insertions to the length of the original text) for the TREC dataset. From Figure , we clearly observe that the BAE attacks are consistently stronger than TextFooler. The classifier models are relatively robust to perturbations up to 20$\\%$, while the effectiveness saturates at 40-50$\\%$. Surprisingly, a 50$\\%$ perturbation for the TREC dataset translates to replacing or inserting just 3-4 words, due to the short text lengths.\nQualitative Examples We present adversarial examples generated by the attacks on a sentence from the IMDB and Yelp datasets in Table . BAE produces more natural looking examples than TextFooler as tokens predicted by the BERT-MLM fit well in the sentence context. TextFooler tends to replace words with complex synonyms, which can be easily detected. Moreover, BAE's additional degree of freedom to insert tokens allows for a successful attack with fewer perturbations.\nHuman Evaluation We consider successful adversarial examples generated from the Amazon and IMDB datasets and verify their sentiment and grammatical correctness. Human evaluators annotated the sentiment and the grammar (Likert scale of 1-5) of randomly shuffled adversarial examples and original texts. From Table , BAE and TextFooler have inferior accuracies compared to the Original, showing they are not always perfect. However, BAE has much better grammar scores, suggesting more natural looking adversarial examples.\nAblation Study We analyze the benefits of R/I operations in BAE in Table . From the table, the splits $\\mathbb {A}$ and $\\mathbb {B}$ are the $\\%$ of test points which compulsorily need I and R operations respectively for a successful attack. We can observe that the split $\\mathbb {A}$ is larger than $\\mathbb {B}$ thereby indicating the importance of the I operation over R. Test points in split require both R and I operations for a successful attack. Interestingly, split is largest for Subj, which is the most robust to attack (Table ) and hence needs both R/I operations. Thus, this study gives positive insights towards the importance of having the flexibility to both replace and insert words.\nRefer to the Appendix for additional results, effectiveness graphs and details of human evaluation.\nWe perform human evaluation of our BAE attacks on the BERT classifier. For 3 datasets, we consider 100 samples from each test set shuffled randomly with their successful adversarial examples from BAE-R, BAE-R+I and TextFooler.",

        "question": "Given these paragraphs about Large language models, what popular neural network architecture architecture are they based on?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

Gravity is, by far, the weakest of the four fundamental interactions, approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light.\n\nOn Earth, gravity gives weight to physical objects, and the Moon's gravity is responsible for sublunar tides in the oceans (the corresponding antipodal tide is caused by the inertia of the Earth and Moon orbiting one another). Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. Investigation into the effects of weightlessness has shown that gravity may play a role in immune system function and cell differentiation within the human body.\n\nThe gravitational attraction between the original gaseous matter in the universe allowed it to coalesce and form stars which eventually condensed into galaxies, so gravity is responsible for many of the large-scale structures in the universe. Gravity has an infinite range, although its effects become weaker as objects get farther away.\n\nGravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines. The most extreme example of this curvature of spacetime is a black hole, from which nothing—not even light—can escape once past the black hole's event horizon However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force causing any two bodies to be attracted toward each other, with magnitude proportional to the product of their masses and inversely proportional to the square of the distance between them.",
        "answer": "In general physics theory (Newton), Gravity is a mutual attraction between objects based on their respective masses and the square of the distance which separates them. In the relativity theory (Einstein), it's a curvature of the spacetime generated by the objects themselves.",

        "question": "Why do the authors propose an abstract problem?",
        "answer": "Formulate as a well-defined OKBC problem in the interactive setting.",
        "evidence": "Chatbots such as dialog and question-answering systems have a long history in AI and natural language processing. Early such systems were mostly built using markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Recent neural conversation models BIBREF4 , BIBREF5 , BIBREF6 are even able to perform open-ended conversations. However, since they do not use explicit knowledge bases and do not perform inference, they often suffer from generic and dull responses BIBREF5 , BIBREF7 . More recently, BIBREF8 and BIBREF9 proposed to use knowledge bases (KBs) to help generate responses for knowledge-grounded conversation. However, one major weakness of all existing chat systems is that they do not explicitly or implicitly learn new knowledge in the conversation process. This seriously limits the scope of their applications. In contrast, we humans constantly learn new knowledge in our conversations. Even if some existing systems can use very large knowledge bases either harvested from a large data source such as the Web or built manually, these KBs still miss a large number of facts (knowledge) BIBREF10 . It is thus important for a chatbot to continuously learn new knowledge in the conversation process to expand its KB and to improve its conversation ability.\nIn recent years, researchers have studied the problem of KB completion, i.e., inferring new facts (knowledge) automatically from existing facts in a KB. KB completion (KBC) is defined as a binary classification problem: Given a query triple, ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ), we want to predict whether the source entity INLINEFORM3 and target entity INLINEFORM4 can be linked by the relation INLINEFORM5 . However, existing approaches BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 solve this problem under the closed-world assumption, i.e., INLINEFORM6 , INLINEFORM7 and INLINEFORM8 are all known to exist in the KB. This is a major weakness because it means that no new knowledge or facts may contain unknown entities or relations. Due to this limitation, KBC is clearly not sufficient for knowledge learning in conversations because in a conversation, the user can say anything, which may contain entities and relations that are not already in the KB.\nIn this paper, we remove this assumption of KBC, and allow all INLINEFORM0 , INLINEFORM1 and INLINEFORM2 to be unknown. We call the new problem open-world knowledge base completion (OKBC). OKBC generalizes KBC. Below, we show that solving OKBC naturally provides the ground for knowledge learning and inference in conversations. In essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.\nFrom the perspective of knowledge learning in conversations, essentially we can extract two key types of information, true facts and queries, from the user utterances. Queries are facts whose truth values need to be determined. Note that we do not study fact or relation extraction in this paper as there is an extensive work on the topic. (1) For a true fact, we will incorporate it into the KB. Here we need to make sure that it is not already in the KB, which involves relation resolution and entity linking. After a fact is added to the KB, we may predict that some related facts involving some existing relations in the KB may also be true (not logical implications as they can be automatically inferred). For example, if the user says “Obama was born in USA,” the system may guess that (Obama, CitizenOf, USA) (meaning that Obama is a citizen of USA) could also be true based on the current KB. To verify this fact, it needs to solve a KBC problem by treating (Obama, CitizenOf, USA) as a query. This is a KBC problem because the fact (Obama, BornIn, USA) extracted from the original sentence has been added to the KB. Then Obama and USA are in the KB. If the KBC problem is solved, it learns a new fact (Obama, CitizenOf, USA) in addition to the extracted fact (Obama, BornIn, USA). (2) For a query fact, e.g., (Obama, BornIn, USA) extracted from the user question “Was Obama born in USA?” we need to solve the OKBC problem if any of “Obama, “BornIn”, or “USA\" is not already in the KB.\nWe can see that OKBC is the core of a knowledge learning engine for conversation. Thus, in this paper, we focus on solving it. We assume that other tasks such as fact/relation extraction and resolution and guessing of related facts of an extracted fact are solved by other sub-systems.\nWe solve the OKBC problem by mimicking how humans acquire knowledge and perform reasoning in an interactive conversation. Whenever we encounter an unknown concept or relation while answering a query, we perform inference using our existing knowledge. If our knowledge does not allow us to draw a conclusion, we typically ask questions to others to acquire related knowledge and use it in inference. The process typically involves an inference strategy (a sequence of actions), which interleaves a sequence of processing and interactive actions. A processing action can be the selection of related facts, deriving inference chain, etc., that advances the inference process. An interactive action can be deciding what to ask, formulating a suitable question, etc., that enable us to interact. The process helps grow the knowledge over time and the gained knowledge enables us to communicate better in the future. We call this lifelong interactive learning and inference (LiLi). Lifelong learning is reflected by the facts that the newly acquired facts are retained in the KB and used in inference for future queries, and that the accumulated knowledge in addition to the updated KB including past inference performances are leveraged to guide future interaction and learning. LiLi should have the following capabilities:\nThis setting is ideal for many NLP applications like dialog and question-answering systems that naturally provide the scope for human interaction and demand real-time inference.\nLiLi starts with the closed-world KBC approach path-ranking (PR) BIBREF11 , BIBREF17 and extends KBC in a major way to open-world knowledge base completion (OKBC). For a relation INLINEFORM0 , PR works by enumerating paths (except single-link path INLINEFORM1 ) between entity-pairs linked by INLINEFORM2 in the KB and use them as features to train a binary classifier to predict whether a query INLINEFORM3 should be in the KB. Here, a path between two entities is a sequence of relations linking them. In our work, we adopt the latest PR method, C-PR BIBREF16 and extend it to make it work in the open-world setting. C-PR enumerates paths by performing bidirectional random walks over the KB graph while leveraging the context of the source-target entity-pair. We also adopt and extend the compositional vector space model BIBREF20 , BIBREF21 with continual learning capability for prediction.\nGiven an OKBC query ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ) (e.g., “(Obama, CitizenOf, USA), which means whether Obama a citizen of USA), LiLi interacts with the user (if needed) by dynamically formulating questions (see the interaction example in Figure 1, which will be further explained in §3) and leverages the interactively acquired knowledge (supporting facts (SFs) in the figure) for continued inference. To do so, LiLi formulates a query-specific inference strategy and executes it. We design LiLi in a Reinforcement Learning (RL) setting that performs sub-tasks like formulating and executing strategy, training a prediction model for inference, and knowledge retention for future use. To the best of our knowledge, our work is the first to address the OKBC problem and to propose an interactive learning mechanism to solve it in a continuous or lifelong manner. We empirically verify the effectiveness of LiLi on two standard real-world KBs: Freebase and WordNet. Experimental results show that LiLi is highly effective in terms of its predictive performance and strategy formulation ability.\nIn essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.",

        "question": "What are the two important caveats of the previous work that hinder precision in the descriptions?",
        "answer": "Linearization of the data structure and Arbitrary ordering of unordered collections in RNN.",
        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nAlthough previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions: 1.

        "question": "When and why was the plaxton coach production halted?",
        "evidence": "By 1936 the company felt justified in constructing a large new manufacturing facility in Seamer Road, Scarborough. This allowed increased production, and Plaxtons became popular with many independent operators throughout Northern England. Many of these operators purchased their vehicles through independent dealers, rather than directly from the factory. In this regard, Plaxton's sales were through Lancashire Motor Traders Ltd of Manchester and Arlington Motor Co Ltd of London. The company became known as FW Plaxton & Son by 1937, as the founder's son, also named Frederick William joined the company at the age of 18. FW Plaxton junior was to be known as Eric to avoid confusion with his father.\n\nPlaxtons built a number of different coach designs through the 1930s, until settling on a distinctive house style. The style typically consisted of a very rounded front profile at the windscreen area with side windows that sloped backwards at the front, were upright at the centre, and sloped forward at the back. Bodywork for the Bedford WTB chassis was particularly distinctive, sloping severally from the bottom of the front wheel arch to the roofline, leaving the \"bullnose\" radiator grille protruding. The rear also sloped prominently. The WTB chassis was very popular choice for operators at that time, together with the Dodge RBF and SBF. Leyland and AEC chassis were also popular for larger coaches, notably the Leyland Tiger and AEC Regal.\n\nOn the outbreak of World War II in 1939, coach production halted and the factory was turned into a munitions factory under the control of the Ministry of Aircraft Production. Many records from the early years were lost when an incendiary bomb set fire to the Seamer Road factory in 1943, causing much damage. As the factory was under control of the Ministry of Works, production continued in the open air whilst a replacement was constructed. Some adjacent land was loaned by a market gardener who subsequently joined the board years later.",

In particular, the improvements over the Baseline model show that a combination of local and global contextual information does help to identify the most important sentences.",
        "evidence": "For evaluation, we follow the same procedure as in BIBREF18 . Summaries are generated by selecting the top ranked sentences by model probability INLINEFORM0 , until the length limit is met or exceeded. Based on the average length of abstracts in these two datasets, we set the length limit to 200 words. We use ROUGE scores BIBREF30 and METEOR scores BIBREF31 between the model results and ground-truth abstractive summaries as evaluation metric. The unigram and bigram overlap (ROUGE-1,2) are intended to measure the informativeness, while longest common subsequence (ROUGE-L) captures fluency to some extent BIBREF2 . METEOR was originally proposed to evaluate translation systems by measuring the alignment between the system output and reference translations. As such, it can also be used as an automatic evaluation metric for summarization BIBREF18 .\nThe performance of all models on arXiv and Pubmed is shown in Table TABREF28 and Table TABREF29 , respectively. Follow the work BIBREF18 , we use the approximate randomization as the statistical significance test method BIBREF32 with a Bonferroni correction for multiple comparisons, at the confidence level 0.01 ( INLINEFORM0 ). As we can see in these tables, on both datasets, the neural extractive models outperforms the traditional extractive models on informativeness (ROUGE-1,2) by a wide margin, but results are mixed on ROUGE-L. Presumably, this is due to the neural training process, which relies on a goal standard based on ROUGE-1. Exploring other training schemes and/or a combination of traditional and neural approaches is left as future work. Similarly, the neural extractive models also dominate the neural abstractive models on ROUGE-1,2, but these abstractive models tend to have the highest ROUGE-L scores, possibly because they are trained directly on gold standard abstract summaries.\nCompared with other neural extractive models, our models (both with attentive context and concatenation decoder) have better performances on all three ROUGE scores, as well as METEOR. In particular, the improvements over the Baseline model show that a combination of local and global contextual information does help to identify the most important sentences (more on this in the next section). Interestingly, just the Baseline model already achieves a slightly better performance than previous works; possibly because the auto-regressive approach used in those models is even more detrimental for long documents.\nFigure FIGREF32 shows the most important result of our analysis: the benefits of our method, explicitly designed to deal with longer documents, do actually become stronger as we apply it to longer documents. As it can be seen in Figure FIGREF32 , the performance gain of our model with respect to current state-of-the-art extractive summarizer is more pronounced for documents with INLINEFORM0 words in both datasets.\nFinally, the result of Lead (Table TABREF28 , TABREF29 ) shows that scientific papers have less position bias than news; i.e., the first sentences of these papers are not a good choice to form an extractive summary.\nAs a teaser for the potential and challenges that still face our approach, its output (i.e., the extracted sentences) when applied to this paper is colored in red and the order in which the sentences are extracted is marked with the Roman numbering. If we set the summary length limit to the length of our abstract, the first five sentences in the conclusions section are extracted. If we increase the length to 200 words, two more sentences are extracted, which do seem to provide useful complementary information. Not surprisingly, some redundancy is present, as dealing explicitly with redundancy is not a goal of our current proposal and left as future work.\nCompared with other neural extractive models, our models (both with attentive context and concatenation decoder) have better performances on all three ROUGE scores, as well as METEOR.

YouTube was also ordered to create systems to increase children's privacy. Following criticisms of its implementation of those systems, YouTube started treating all videos designated as \"made for kids\" as liable under COPPA on January 6, 2020. Joining the YouTube Kids app, the company created a supervised mode, designed more for tweens, in 2021. Additionally, to compete with TikTok, YouTube released YouTube Shorts, a short-form video platform.\n\nDuring this period, YouTube entered disputes with other tech companies. For over a year, in 2018 and 2019, no YouTube app was available for Amazon Fire products. In 2020, Roku removed the YouTube TV app from its streaming store after the two companies were unable to reach an agreement.\n\nAfter testing earlier in 2021, YouTube removed public display of dislike counts on videos in November 2021, claiming the reason for the removal was, based on its internal research, that users often used the dislike feature as a form of cyberbullying and brigading. While some users praised the move as a way to discourage trolls, others felt that hiding dislikes would make it harder for viewers to recognize clickbait or unhelpful videos and that other features already existed for creators to limit bullying. YouTube co-founder Jawed Karim referred to the update as \"a stupid idea\", and that the real reason behind the change was \"not a good one, and not one that will be publicly disclosed.\" He felt that users' ability on a social platform to identify harmful content was essential, saying, \"The process works, and there's a name for it: the wisdom of the crowds. The process breaks when the platform interferes with it. Then, the platform invariably declines.\" Shortly after the announcement, software developer Dmitry Selivanov created Return YouTube Dislike, an open-source, third-party browser extension for Chrome and Firefox that allows users to see a video's number of dislikes. In a letter published on January 25, 2022 by then YouTube CEO Susan Wojcicki, acknowledged that removing public dislike counts was a controversial decision, but reiterated that she stands by this decision, claiming that \"it reduced dislike attacks.\"\n\nIn 2022, YouTube launched an experiment where the company would show users who watched longer videos on TVs a long chain of short unskippable adverts, intending to consolidate all ads into the beginning of a video. Following public outrage over the unprecedented amount of unskippable ads, YouTube \"ended\" the experiment on September 19 of that year. In October, YouTube announced that they would be rolling out customizable user handles (e.g. @MrBeast6000) in addition to channel names, which would also become channel URLs.\n\nOn February 16, 2023, Wojcicki announced that she would step down as CEO, with Neal Mohan named as her successor.

Relevant features proposed in the literature span from microblogging artifacts including hashtags, emoticons BIBREF0 , BIBREF1 , intensifiers like all-caps words and character repetitions BIBREF2 , sentiment-topic features BIBREF3 , to the inclusion of polarity lexicons.\nThe objective of the work presented in this paper is the creation of sentiment polarity lexicons. They are word lists or phrase lists with positive and negative sentiment labels. Sentiment lexicons allow to increase the feature space with more relevant and generalizing characteristics of the input. Unfortunately, creating sentiment lexicons requires human expertise, is time consuming, and often results in limited coverage when dealing with new domains.\nIn the literature, it has been proposed to extend existing lexicons without supervision BIBREF4 , BIBREF5 , or to automatically translate existing lexicons from resourceful languages with statistical machine translation (SMT) systems BIBREF6 . While the former requires seed lexicons, the later are very interesting because they can automate the process of generating sentiment lexicons without any human expertise. But automatically translating sentiment lexicons leads to two problems: (1) out-of-vocabulary words, such as mis-spellings, morphological variants and slang, cannot be translated, and (2) machine translation performance strongly depends on available training resources such as bi-texts.\nIn this paper, we propose to apply the method proposed in BIBREF7 for automatically mapping word embeddings across languages and use them to translate sentiment lexicons only given a small, general bilingual dictionary. After creating monolingual word embeddings in the source and target language, we train a linear transform on the bilingual dictionary and apply that transform to words for which we don't have a translation.\nWe perform experiments on 3-class polarity classification in tweets, and report results on four different languages: French, Italian, Spanish and German.

According to the structured rule of its, Vietnamese can have about 20,000 different syllables (tokens). However, there are about 8,000 syllables used the Vietnamese dictionaries.

In our research for Vietnamese, we consider the morpheme as syllable, called “tiếng” in Vietnamese (as Nguyen’s definition BIBREF12 ).\nThe next concept in linguistics is word which has fully grammar and meaning function in sentences. For Vietnamese, word is a single morpheme or a group of morphemes, which are fixed and have full meaning BIBREF12 . According to Nguyen, Vietnamese words are able classified into two types, (1) 1- syllable words with fully meaning and (2) n-syllables words whereas these group of tokens are fixed. Vietnamese syllable is not fully meaningful. However, it is also explained in the meaning and structure characteristics. For example, the token “kỳ” in “quốc kỳ” whereas “quốc” means national, “kỳ” means flag.

In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS.",

        "answer": "Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects a child's social communication and interaction, as well as their behavior and interests. Children with autism may have difficulty understanding social cues and may struggle to express their emotions, which can make it challenging for them to navigate social situations and communicate effectively.\n\nChildren with autism may also experience sensory processing difficulties, where they are either over or under sensitive to different sensory stimuli, such as sound, touch, taste, or smell. This can lead to sensory overload and cause them to become overwhelmed or upset.\n\nWhen a child with autism experiences a challenging situation, such as a conflict with another child, their reaction can vary. They may struggle to communicate their feelings effectively, which can lead to frustration or even aggression. In some cases, they may become overwhelmed by their emotions and engage in self-injurious behavior, such as hitting or biting themselves.\n\nIt's important to remember that every child with autism is unique, and their experience of fighting with autism may vary depending on their individual strengths and challenges. However, with early diagnosis, proper support, and effective intervention, children with autism can learn to manage their emotions and develop positive social skills to navigate social situations successfully.",

        "question": "As a golfer, how can I fix my slice?",
        "evidence": "",
        "answer": "A common swing fault in golfers is a slice which is caused when the face of the club isn't aligned properly to the swing path of the club.  What will typically happen is at the time of impact, the face is open in relation to the target (ie aimed to the right if you are a right handed golfer) and the swing path is closed in relation to the target (ie aimed to the left if you are a left handed golfer).  When there is a large difference between the path of the swing and the face of the club, the impact will generate a high degree of lateral spin on the ball causing the flight of the ball to curve away from the target.  Here are some ways to fix this swing fault:\n\n1. Grip the club with a stronger grip.  This means the v formed between your thumb and pointer finger on back hand is pointed to your rear shoulder and your opposite hand it also gripping the club more from the back.  This will help you close the face of the club at impact.\n2. Focus on keeping the face closed in the backswing.  One fault many amateurs have is the club face opens toward the sky on the backswing too far meaning that the face will need to turn more on the downswing to get to square at impact.  Creating less rotation on the backswing can help with this.  \n3. Keeping hips down and back in the downswing.  One fault that can cause inconsistent contact as well as a slice is when the hips thrust forward during the downswing causing the golfer to lift up to counter being too close to the ball which can often cause an over the top, out-to-in swing path.  Try to keep the hips back through the swing and focus on rotating the body to keep forward or lateral movement to a minimum.  \n\nA slice is a very common issue among golfers but knowing the causes and swing faults that lead to a slice can help you think about how you can improve your swing to fix it.",

More details of our evaluation protocol can be found in the paragraph titled \"Evaluation Protocol\" in Section 3. We are happy to clarify any details if something is unclear.",
        "evidence": "Our template-based parameterization maps the accelerator, denoted as x, to a discrete design space,\nand each x i is a discrete-valued variable representing one component of the microarchitectural template, as shown in Table (See Appendix C for the description of other accelerator search spaces studied in our work). A design maybe be infeasible due to various reasons, such as a compilation failure or the limitations of physical implementation, and we denote the set of all such feasibility criterion as Feasible(x). The feasibility criterion depends on both the target software and the underlying hardware, and it is not easy to identify if a given x is infeasible without explicit simulation. We will require our optimization procedure to not only learn the value of the objective function but also to learn to navigate through a sea of infeasible solutions to high-performing feasible solutions x * satisfying Feasible(x * ) = 1.\nOur training dataset D consists of a modest set of accelerators x i that are randomly sampled from the design space and evaluated by the hardware simulator. We partition the dataset D into two subsets, D feasible and D infeasible . Let f (x) denote the desired objective (e.g., latency, power, etc.) we intend to optimize over the space of accelerators x. We do not possess functional access to f (x), and the optimizer can only access f (x) values for accelerators x in the feasible partition of the data, D feasible . For all infeasible accelerators, the simulator does not provide any value of f (x). In addition to satisfying feasibility, the optimizer must handle explicit constraints on parameters such as area and power. In our applications, we impose an explicit area constraint, Area(x) ≤ α 0 , though additional explicit constraints are also possible. To account for different constraints, we formulate this task as a constrained optimization problem. Formally:\nWhile Equation 1 may appear similar to other standard black-box optimization problems, solving it over the space of accelerator designs is challenging due to the large number of infeasible points, the need to handle explicit design constraints, and the difficulty in navigating the non-smooth landscape (See Figure and Figure in the Appendix) of the objective function.\nWhat makes optimization over accelerators challenging? Compared to other domains where model-based optimization methods have been applied, optimizing accelerators introduces a number of practical challenges. First, accelerator design spaces typically feature a narrow manifold of feasible accelerators within a sea of infeasible points, as visualized in Figure and Appendix (Figure). While some of these infeasible points can be identified via simple rules (e.g. estimating chip area usage), most infeasible points correspond to failures during compilation or hardware simulation. These infeasible points are generally not straightforward to formulate into the optimization problem and requires simulation.\nSecond, the optimization objective can exhibit high sensitivity to small variations in some architecture parameters (Figure) in some regions of the design space, but remain relatively insensitive in other parts, resulting in a complex optimization landscape. This suggests that optimization algorithms based on local parameter updates (e.g., gradient ascent, evolutionary schemes, etc.) may have a challenging task traversing the nearly flat landscape of the objective, which can lead to poor performance. Training dataset. We used an offline dataset D of (accelerator parameters, latency) via random sampling from the space of 452M possible accelerator configurations. Our method is only provided with a relatively modest set of feasible points (≤ 8000 points) for training, and these points are the worst-performing feasible points across the pool of randomly sampled data. This dataset is meant to reflect an easily obtainable and an application-agnostic dataset of accelerators that could have been generated once and stored to disk, or might come from real physical experiments. We emphasize that no assumptions or domain knowledge about the application use case was made during dataset collection. Table depicts the list of target applications, evaluated in this work, includes three variations of MobileNet, three in-house industry-level models for object detection (M4, M5, M6; names redacted to prevent anonymity violation), a U-net model, and two RNN-based encoderdecoder language models. These applications span the gamut from small models, such as M6, with only 0.4 MB model parameters that demands less on-chip memory, to the medium-sized models (≥ 5 MB), such as MobileNetV3 and M4 models, and large models (≥ 19 MB), such as t-RNNs, hence requiring larger on-chip memory.\nEvaluation protocol. To compare state-of-the-art simulator-driven methods and our data-driven method, we limit the number of feasible points (costly to evaluate) that can be used by any algorithm to equal amounts. We still provide infeasible points to any method and leave it up to the optimization method to use it or not. This ensures our comparisons are fair in terms of the amount of data available to each method. However, it is worthwhile to note that in contrast to our method where worse-quality data points from small offline dataset are used, the simulator-driven methods have an inherent advantage because they can steer the query process towards the points that are more likely to be better in terms of performance. Following prior work, we evaluate each run of a method by first sampling the top n = 256 design candidates according to the algorithm's predictions, evaluating all of these under the ground truth objective function and recording the performance of the best accelerator design. The final reported results is the median of ground truth objective values across five independent runs.\nEvaluation protocol.

On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications.

In our experiments, the RNN takes in spectrograms of utterances, passing them through two 2D-convolutional layers, followed by seven bi-directional recurrent layers and a fully-connected layer with softmax activation. All recurrent layers are batch normalized. At each timestep, the softmax activations give a probability distribution over the characters. CTC loss BIBREF8 is then computed from the timestep-wise probabilities.\nA base model, INLINEFORM0 , is trained on 190 hours ( INLINEFORM1 100K instances) of transcribed speech data. Then, it selects a subset of a 1,700-hour ( INLINEFORM2 1.1M instances) unlabeled dataset. We query labels for the selected subset and incorporate them into training. Learning rates are tuned on a small validation set of 2048 instances. The trained model is then tested on a 156-hour ( INLINEFORM3 100K instances) test set and we report CTC loss, Character Error Rate (CER) and Word Error Rate (WER).\nThe confidence score methods BIBREF1 , BIBREF2 can be easily extended to our setup. Specifically, from the probabilities over the characters, we can compute an entropy per timestep and then average them. This method is denoted as entropy. We could also take the most likely prediction and calculate its CTC loss, normalized by number of timesteps. This method is denoted as pCTC (predicted CTC) in the following sections.\nWe implement EGL by marginalizing over the most likely 100 labels, and compare it with: 1) a random selection baseline, 2) entropy, and 3) pCTC. Using the same base model, each method queries a variable percentage of the unlabeled dataset. The queries are then included into training set, and the model continues training until convergence. Fig. FIGREF9 reports the metrics (Exact values are reported in Table TABREF12 in the Appendix) on the test set as the query percentage varies. All the active learning methods outperform the random baseline. Moreover, EGL shows a steeper, more rapid reduction in error than all other approaches. Specifically, when querying 20% of the unlabeled dataset, EGL has 11.58% lower CER and 11.09% lower WER relative to random. The performance of EGL at querying 20% is on par with random at 40%, suggesting that using EGL can lead to an approximate 50% decrease in data labeling.\nThese particular samples consist of short utterances containing silence (with background noise) or filler words.",

This task is to determine borders between words in a sentence. In other words, it is segmenting a list of tokens into a list of words such that words are meaningful.\nWord segmentation is the primary step in prior to other natural language processing tasks i. e., term extraction and linguistic analysis (as shown in Figure 1). It identifies the basic meaningful units in input texts which will be processed in the next steps of several applications. For named entity recognization BIBREF2 , word segmentation chunks sentences in input documents into sequences of words before they are further classified in to named entity classes. For Vietnamese language, words and candidate terms can be extracted from Vietnamese copora (such as books, novels, news, and so on) by using a word segmentation tool. Conformed features and context of these words and terms are used to identify named entity tags, topic of documents, or function words. For linguistic analysis, several linguistic features from dictionaries can be used either to annotating POS tags or to identifying the answer sentences. Moreover, language models can be trained by using machine learning approaches and be used in tagging systems, like the named entity recognization system of Tran et al.

Approaches for word segmentation task are variety, from lexicon-based to machine learning-based methods. Recently, machine learning-based methods are used widely to solve this issue, such as: Support Vector Machine or Conditional Random Fields BIBREF7 , BIBREF8 .

Based on annotated corpora and token-based features, studies used machine learning approaches to build word segmentation systems with accuracy about 94%-97%.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation. A all sided review of word segmentation will help next studies on Vietnamese natural language processing tasks have an up-to-date guideline and choose the most suitable solution for the task. The remaining part of the paper is organized as follows. Section II discusses building corpus in Vietnamese, containing linguistic issues and the building progress. Section III briefly mentions methods to model sentences and text in machine learning systems. Next, learning models and approaches for labeling and segmenting sequence data will be presented in Section IV. Section V mainly addresses two existing toolkits, vnTokenizer and JVnSegmenter, for Vietnamese word segmentation. Several experiments based on mentioned approaches and toolkits are described in Section VI. Finally, conclusions and future works are given in Section VII.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation.

        "answer": "You can look for a few signs to see if your sourdough starter is ready to use. One common sign to look for is whether the starter has at least doubled in volume. Time can be a difficult indicator as how long it takes for a starter to double volume can vary based on temperature, hydration, and other factors. Another sign to look for is a lot of bubbles throughout the starter - this can be seen if your starter is in a glass container. Lastly, get to know your starter as you bake with it because each starter has its own unique characteristics. Learn what it will smell like when it matures - this can help you establish a baseline and identify when something is wrong with the starter as it smells \"funky\".",

We also now included in the updated manuscript dropout experiments and weight-based diversity.",
        "evidence": "Neural networks are a powerful class of non-linear function approximators that have been successfully used to tackle a wide range of problems. They have enabled breakthroughs in many tasks, such as image classification, speech recognition, and anomaly detection. Formally, the output of a neural network consisting of P layers can be defined as follows:\nwhere φ i (.) is the element-wise activation function, e.g., ReLU or Sigmoid, of the i th layer and W = {W 1 , . . . , W P } are the corresponding weights of the network. The parameters of f (x; W) are optimized by minimizing the empirical loss:\nwhere l(•) is the loss function, and {x i , y i } N i=1 are the training samples and their associated groundtruth labels. The loss is minimized using the gradient decent-based optimization coupled with backpropagation.\nHowever, neural networks are often over-parameterized, i.e., have more parameters than data. As a result, they tend to overfit to the training samples and not generalize well on unseen examples. While research on double descent shows that over-parameterization does not necessarily lead to overfitting, avoiding overfitting has been extensively studied and various approaches and strategies have been proposed, such as data augmentation, regularization, and Dropout, to close the gap between the empirical loss and the expected loss. Diversity of learners is widely known to be important in ensemble learning and, particularly in deep learning context, diversity of information extracted by the network neurons has been recognized as a viable way to improve generalization. In most cases, these efforts have focused on making the set of weights more diverse. However, diversity of the activations has not received much attention. Here, we argue that due to the presence of non-linear activations, diverse weights do not guarantee diverse feature representation. Thus, we propose applying the diversity on top of feature mapping instead of the weights.\nTo the best of our knowledge, only have considered diversity of the activations directly in the neural network context. They proposed an additional loss term using cross-covariance of hidden activations, which encourages the neurons to learn diverse or non-redundant representations. Their proposed approach, known as DeCov, was empirically proven to alleviate overfitting and to improve the generalization ability of neural network, yet a theoretical analysis to prove this has so far been lacking. Moreover, modeling diversity as the sum of the pairwise cross-covariance, it can capture only the pairwise diversity between components and is unable to capture the \"higher-order diversity\".\nIn this work, we start by theoretically showing that the within-layer activation diversity boosts the generalization ability of neural networks and reduces overfitting. Moreover, we propose a novel approach to encourage activation diversity within a layer. We propose complementing the 'betweenlayer' feedback with additional 'within-layer' feedback to penalize similarities between neurons on the same layer. Thus, we encourage each neuron to learn a distinctive representation and to enrich the data representation learned within each layer. We propose three variants for our approach that are based on different global diversity definitions.\nOur contributions in this paper are as follows:\n• Theoretically, we derive novel generalization bounds for neural networks depending on the within-layer activation diversity. As shown in Section 2, we express the upper-bound of the estimation error as a function of the diversity factor. Thus, we provide theoretical evidence that the within-layer activation diversity helps reduce the generalization error. • Methodologically, we propose a new approach to encourage the 'diversification' of the layers' output feature maps in neural networks. The proposed approach has three variants.\nThe main intuition is that by promoting the within-layer activation diversity, neurons within a layer learn distinct patterns and, thus, increase the overall capacity of the model. • Empirically, we show that the proposed within-layer activation diversification boosts the performance of neural networks. Experimental results on several tasks show that the proposed approach outperforms competing methods.\nDiversity of learners is widely known to be important in ensemble learning (Li et al., 2012; Yu et al., 2011) and, particularly in deep learning context, diversity of information extracted by the network neurons has been recognized as a viable way to improve generalization (Xie et al., 2017a; 2015b). In most cases, these efforts have focused on making the set of weights more diverse (Yang et al.; Malkin & Bilmes, 2009). However, diversity of the activations has not received much attention. Here, we argue that due to the presence of non-linear activations, diverse weights do not guarantee diverse feature representation. Thus, we propose applying the diversity on top of feature mapping instead of the weights. To the best of our knowledge, only Cogswell et al.

        "answer": "First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.",
        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nAlthough these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.",

        "question": "What are the two types of models performing the word embedding?",
        "answer": "Predictive and counting.",
        "evidence": "Low dimensional word representations (embeddings) have become a key component in modern NLP systems for language modeling, parsing, sentiment classification, and many others. These embeddings are usually derived by employing the distributional hypothesis: that similar words appear in similar contexts BIBREF0 .\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix BIBREF1 . The most well-known predictive model, which has become eponymous with word embedding, is word2vec BIBREF2 . Popular counting models include PPMI-SVD BIBREF3 , GloVe BIBREF4 , and LexVec BIBREF5 .\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.\nfastText BIBREF6 addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors. This addresses both issues above as learned information is shared through the n-gram vectors and from these OOV word representations can be constructed.\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , but the method proposed here should transfer to GloVe unchanged.\nThe LexVec objective is modified such that a word's vector is the sum of all its subword vectors.\nWe compare 1) the use of n-gram subwords, like fastText, and 2) unsupervised morphemes identified using Morfessor BIBREF11 to learn whether more linguistically motivated subwords offer any advantage over simple n-grams.\nTo evaluate the impact subword information has on in-vocabulary (IV) word representations, we run intrinsic evaluations consisting of word similarity and word analogy tasks. The incorporation of subword information results in similar gains (and losses) to that of fastText over Skip-gram. Whereas incorporating n-gram subwords tends to capture more syntactic information, unsupervised morphemes better preserve semantics while also improving syntactic results. Given that intrinsic performance can correlate poorly with performance on downstream tasks BIBREF12 , we also conduct evaluation using the VecEval suite of tasks BIBREF13 , in which\nall subword models, including fastText, show no significant improvement over word-level models.\nWe verify the model's ability to represent OOV words by quantitatively evaluating nearest-neighbors. Results show that, like fastText, both LexVec n-gram and (to a lesser degree) unsupervised morpheme models give coherent answers.\nThis paper discusses related word ( $§$ \"Related Work\" ), introduces the subword LexVec model ( $§$ \"Subword LexVec\" ), describes experiments ( $§$ \"Materials\" ), analyzes results ( $§$ \"Results\" ), and concludes with ideas for future works ( $§$ \"Conclusion and Future Work\" ).\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix (Baroni et al., 2014).",

In this section, we first describe our problem setup and key terminologies by discussing the dataset used. Later, we formalize our problem definition.\nDataset: For our explorations, we use the Craigslist Bargaining dataset (CB) introduced by BIBREF4. Instead of focusing on the previously studied game environments BIBREF5, BIBREF6, the dataset considers a more realistic setup: negotiating the price of products listed on Craigslist. The dataset consists of 6682 dialogues between a buyer and a seller who converse in natural language to negotiate the price of a given product (sample in Table TABREF1). In total, 1402 product ad postings were scraped from Craigslist, belonging to six categories: phones, bikes, housing, furniture, car and electronics. Each ad posting contains details such as Product Title, Category Type and a Listing Price. Moreover, a secret target price is also pre-decided for the buyer. The final price after the agreement is called the Agreed Price, which we aim to predict.\nDefining the problem: Say we are provided with a product scenario $S$, a tuple: (Category, Title, Listing Price, Target Price). Define the interactions between a buyer and seller using a sequence of $n$ events $E_n:<e_{1}, e_{2}, ..., e_{n}>$, where $e_{i}$ occurs before $e_{j}$ iff $i<j$. Event $e_{i}$ is also a tuple: (Initiator, Type, Data). Initiator is either the Buyer or Seller, Type can be one of (message, offer, accept, reject or quit) and Data consists of either the corresponding natural language dialogue, offer price or can be empty. Nearly $80\\%$ of events in CB dataset are of type `message', each consisting a textual message as Data. An offer is usually made and accepted at the end of each negotiation. Since the offers directly contain the agreed price (which we want to predict), we only consider `message' events in our models. Given the scenario $S$ and first $n$ events $E_n$, our problem is then to learn the function $f_{n}$: $A = f_{n}(S, E_n)$ where $A$ refers to the final agreed price between the two negotiating parties.\n\nWe use the Craigslist Bargaining dataset (CB) introduced by He et al.

The process consists of two stages. In the first stage, article–entity placement, we suggest news articles to entity pages by considering three main factors, such as entity salience in a news article, relative authority and novelty of news articles for an entity page. In the second stage, article–section placement, we determine the best fitting section in an entity page. Here, we remedy the problem of incomplete entity section profiles by constructing section templates for specific entity classes. This allows us to add missing sections to entity pages. We carry out an extensive experimental evaluation on 351,983 news articles and 73,734 entities coming from 27 distinct entity classes. For the first stage, we achieve an overall performance with P=0.93, R=0.514 and F1=0.676, outperforming our baseline competitors significantly. For the second stage, we show that we can learn incrementally to determine the correct section for a news article based on section templates. The overall performance across different classes is P=0.844, R=0.885 and F1=0.860.\nIn the future, we will enhance our work by extracting facts from the suggested news articles. Results suggest that the news content cited in entity pages comes from the first paragraphs. However, challenging task such as the canonicalization and chronological ordering of facts, still remain.\nIn the future, we will enhance our work by extracting facts from the suggested news articles.",

        "question": "Is their method transferable?",
        "answer": "Yes.",
        "evidence": "Words with multiple senses commonly exist in many languages. For example, the word bank can either mean a “financial establishment” or “the land alongside or sloping down to a river or lake”, based on different contexts. Such a word is called a “polyseme”. The task to identify the meaning of a polyseme in its surrounding context is called word sense disambiguation (WSD). Word sense disambiguation is a long-standing problem in natural language processing (NLP), and has broad applications in other NLP problems such as machine translation BIBREF0 . Lexical sample task and all-word task are the two main branches of WSD problem. The former focuses on only a pre-selected set of polysemes whereas the later intends to disambiguate every polyseme in the entire text. Numerous works have been devoted in WSD task, including supervised, unsupervised, semi-supervised and knowledge based learning BIBREF1 . Our work focuses on using supervised learning to solve all-word WSD problem.\nMost supervised approaches focus on extracting features from words in the context. Early approaches mostly depend on hand-crafted features. For example, IMS by BIBREF2 uses POS tags, surrounding words and collections of local words as features. These approaches are later improved by combining with word embedding features BIBREF0 , which better represents the words' semantic information in a real-value space. However, these methods neglect the valuable positional information between the words in the sequence BIBREF3 . The bi-directional Long-Short-Term-Memory (LSTM) approach by BIBREF3 provides one way to leverage the order of words. Recently, BIBREF4 improved the performance by pre-training a LSTM language model with a large unlabelled corpus, and using this model to generate sense vectors for further WSD predictions. However, LSTM significantly increases the computational complexity during the training process.\nThe development of the so called “fixed-size ordinally forgetting encoding” (FOFE) has enabled us to consider more efficient method. As firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence. FOFE has been applied to several NLP problems in the past, such as language model BIBREF5 , named entity recognition BIBREF6 , and word embedding BIBREF7 . The promising results demonstrated by the FOFE approach in these areas inspired us to apply FOFE in solving the WSD problem. In this paper, we will first describe how FOFE is used to encode sequence of any length into a fixed-size representation. Next, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data. Lastly, we provide the experiment results of our method on several WSD data sets to justify the equivalent performance as the state-of-the-art approach.\nWe also show that the methodology can be used for transferring to entirely different tasks.",

In order to quantify the contribution of the different system components we have defined different scenarios. In scenario A, we have analysed the effect of using LDA instead of NDA. As can be seen from the results, LDA outperforms NDA in the case of PLP, however, in fusion we can see that NDA resulted in better performance in terms of the primary metric. In scenario B, we analysed the effect of using the short-duration compensation technique proposed in Section SECREF7 . Results indicate superior performance using this technique. In scenario C, we investigated the effects of language normalization on the performance of the system. If we replace LN-LDA with simple LDA, we can see performance degradation in MFCC as well as fusion, however, PLP seems not to be adversely affected. The effect of using QMF is also investigated in scenario D. Finally in scenario E, we can see the major improvement obtained through the use of the domain adaptation technique explained in Section SECREF16 . For our secondary submission, we incorporated a disjoint portion of the labelled development set (10 out of 20 speakers) in either LN-LDA and in-domain PLDA training.

        "answer": "Substituting difficult words using more common words",
        "evidence": "Automatic TS is a complicated natural language processing (NLP) task, which consists of lexical and syntactic simplification levels BIBREF12 . It has attracted much attention recently as it could make texts more accessible to wider audiences, and used as a pre-processing step, improve performances of various NLP tasks and systems BIBREF13 , BIBREF14 , BIBREF15 . Usually, hand-crafted, supervised, and unsupervised methods based on resources like English Wikipedia and Simple English Wikipedia (EW-SEW) BIBREF10 are utilized for extracting simplification rules. It is very easy to mix up the automatic TS task and the automatic summarization task BIBREF3 , BIBREF16 , BIBREF6 . TS is different from text summarization as the focus of text summarization is to reduce the length and redundant content.\nAt the lexical level, lexical simplification systems often substitute difficult words using more common words, which only require a large corpus of regular text to obtain word embeddings to get words similar to the complex word BIBREF1 , BIBREF9 . Biran et al. BIBREF0 adopted an unsupervised method for learning pairs of complex and simpler synonyms from a corpus consisting of Wikipedia and Simple Wikipedia. At the sentence level, a sentence simplification model was proposed by tree transformation based on statistical machine translation (SMT) BIBREF3 . Woodsend and Lapata BIBREF17 presented a data-driven model based on a quasi-synchronous grammar, a formalism that can naturally capture structural mismatches and complex rewrite operations. Wubben et al. BIBREF18 proposed a phrase-based machine translation (PBMT) model that is trained on ordinary-simplified sentence pairs. Xu et al. BIBREF19 proposed a syntax-based machine translation model using simplification-specific objective functions and features to encourage simpler output.\nCompared with SMT, neural machine translation (NMT) has shown to produce state-of-the-art results BIBREF5 , BIBREF7 . The central approach of NMT is an encoder-decoder architecture implemented by recurrent neural networks, which can represent the input sequence as a vector, and then decode that vector into an output sequence. Therefore, NMT models were used for text simplification task, and achieved good results BIBREF8 , BIBREF4 , BIBREF20 . The main limitation of the aforementioned NMT models for text simplification depended on the parallel ordinary-simplified sentence pairs. Because ordinary-simplified sentence pairs are expensive and time-consuming to build, the available largest data is EW-SEW that only have 296,402 sentence pairs. The dataset is insufficiency for NMT model if we want to NMT model can obtain the best parameters. Considering simplified data plays an important role in boosting fluency for phrase-based text simplification, and we investigate the use of simplified data for text simplification. We are the first to show that we can effectively adapt neural translation models for text simplifiation with simplified corpora.\nAt the lexical level, lexical simplification systems often substitute difficult words using more common words, which only require a large corpus of regular text to obtain word embeddings to get words similar to the complex word (Paetzold and Specia, 2016; Glavaˇs and ˇStajner, 2015).",

        "evidence": "We evaluate the performance of our model primarily on the MNIST dataset. Our model is able to approximate any conditional distribution. Here we demonstrate how to model missing pixels and the class digits conditioned on the observed pixels, as well as model missing pixels conditioned on class digits and observed pixels. Although MNIST is of course a small-scale problem, the goal here is to demonstrate joint inference and learning over what is still a reasonably-sized joint model, considering the number of hidden units. Nonetheless, the current experiment is admittedly largely a demonstration of the proposed method rather than a full accounting of its performance, a point we highlight in the subsequent section as well. After describing the MNIST experiments, we detail a similar experiment on CIFAR-10 to demonstrate the potential for scaling the approach.\nWe also show how our inference method differs from the previous ones. On the joint imputation and classification task, we train models using our updates and the updates in;, and inference each using all three update methods, with and without the monotonicity constraint. We show that our inference method is superior in both performance and convergence speed. Numerically, we also demonstrate that the other two methods could either diverge or not converging to the actual mean-field fixed point. All deferred experiments and details can be found in the appendix.\nExperiment setup The original MNIST dataset has one channel representing the gray-scale intensity, ranging between 0 and 1. Here we adopt the strategy of to convert this continuous distribution to a discrete one. We bin the intensity evenly to 4 categories {0, . . . , 3}, and for each channel uses a one-hot encoding of the category so that the input data has shape 4×28×28.\nWe remark that the number of categories is chosen arbitrarily and can be any integer. For image with missing data, if the pixels are randomly masked, we always mask each pixel off independently with probability 60%, such that in expectation only 40% pixels are observed. If a whole patch of pixels is masked, we randomly pick a 14 × 14 patch. The patches/masks are chosenly differently for every image, similar to the query training in. To make the model class richer, in the patch case we lift the monotonicity constraint, and the model converges regardless. We also conduct the same set of MNIST experiments using a 3-layer DBM and include the results in the appendix.\nTraining the above described model for 40 epochs with 40% missing pixels leads to a 92.95% test accuracy, and the image reconstruction result is shown in fig..

        "question": "Based on the following passage, give 3 reasons why the Sixteenth Amendment was passed and ratified.",
        "evidence": "An income tax amendment to the Constitution was first proposed by Senator Norris Brown of Nebraska. He submitted two proposals, Senate Resolutions Nos. 25 and 39. The amendment proposal finally accepted was Senate Joint Resolution No. 40, introduced by Senator Nelson W. Aldrich of Rhode Island, the Senate majority leader and Finance Committee Chairman. The amendment was proposed as part of the congressional debate over the 1909 Payne–Aldrich Tariff Act; by proposing the amendment, Aldrich hoped to temporarily defuse progressive calls for the imposition of new taxes in the tariff act. Aldrich and other conservative leaders in Congress largely opposed the actual ratification of the amendment, but they believed that it had little chance of being ratified, as ratification required approval by three quarters of the state legislatures.\n\nOn July 12, 1909, the resolution proposing the Sixteenth Amendment was passed by the Congress and was submitted to the state legislatures. Support for the income tax was strongest in the western and southern states, while opposition was strongest in the northeastern states. Supporters of the income tax believed that it would be a much better method of gathering revenue than tariffs, which were the primary source of revenue at the time. From well before 1894, Democrats, Progressives, Populists and other left-oriented parties argued that tariffs disproportionately affected the poor, interfered with prices, were unpredictable, and were an intrinsically limited source of revenue. The South and the West tended to support income taxes because their residents were generally less prosperous, more agricultural and more sensitive to fluctuations in commodity prices. A sharp rise in the cost of living between 1897 and 1913 greatly increased support for the idea of income taxes, including in the urban Northeast. A growing number of Republicans also began supporting the idea, notably Theodore Roosevelt and the \"Insurgent\" Republicans (who would go on to form the Progressive Party). These Republicans were driven mainly by a fear of the increasingly large and sophisticated military forces of Japan, Britain and the European powers, their own imperial ambitions, and the perceived need to defend American merchant ships. Moreover, these progressive Republicans were convinced that central governments could play a positive role in national economies. A bigger government and a bigger military, they argued, required a correspondingly larger and steadier source of revenue to support it.\n\nOpposition to the Sixteenth Amendment was led by establishment Republicans because of their close ties to wealthy industrialists, although not even they were uniformly opposed to the general idea of a permanent income tax. In 1910, New York Governor Charles Evans Hughes, shortly before becoming a Supreme Court Justice, spoke out against the income tax amendment. Hughes supported the idea of a federal income tax, but believed the words \"from whatever source derived\" in the proposed amendment implied that the federal government would have the power to tax state and municipal bonds. He believed this would excessively centralize governmental power and \"would make it impossible for the state to keep any property\".\n\nBetween 1909 and 1913, several conditions favored passage of the Sixteenth Amendment. Inflation was high and many blamed federal tariffs for the rising prices. The Republican Party was divided and weakened by the loss of Roosevelt and the Insurgents who joined the Progressive Party, a problem that blunted opposition even in the Northeast. In 1912, the Democrats won the presidency and control of both houses of Congress. The country was generally in a left-leaning mood, with a member of the Socialist Party winning a seat in the U.S. House in 1910 and the party's presidential candidate polling six percent of the popular vote in 1912.\n\nThree advocates for a federal income tax ran in the presidential election of 1912. On February 25, 1913, Secretary of State Philander Knox proclaimed that the amendment had been ratified by three-fourths of the states and so had become part of the Constitution. The Revenue Act of 1913, which greatly lowered tariffs and implemented a federal income tax, was enacted shortly after the Sixteenth Amendment was ratified.",
        "answer": "Reasons the Sixteenth Amendment to the US constitution was passed by Congress in 1909 and ratified by the states in 1913 include:\n1. Democrats and progressives believed the income tax to be fairer method of generating revenue than tariffs (taxes on the import and export of goods).\n2. Western and southern states were concerned about commodity prices, which were impacted by tariffs, and therefore preferred an alternative means of revenue.\n3. Republicans were split on whether to oppose or support amendment.",

        "question": "Please give me a short bulleted list of the theories that explain different aspects of the relationship between the work and family life made in this passage.",
        "evidence": "Dominant theories of the relationship\nSeveral theories explain different aspects of the relationship between the work and family life. Boundary theory and border theory are the two fundamental theories that researchers have used to study these role conflicts. Other theories are built upon the foundations of these two theories. In the two decades since boundary theory and border theory were first proposed, the rise of Information and Communication Technologies (ICT) has drastically altered the work–life interface. Work can now be completed at any time and in any location, meaning that domains are more likely to be blended and boundaries barely exist.\n\nSeven dominant theories have been utilized to explain this relationship on the boundary-border spectrum; These theories are: structural functioning, segmentation, compensation, supplemental and reactive compensation, role enhancement, spillover, and work enrichment model.\n\nStructural functionalism\nThe roots of this theory can be traced back to the early 20th century, when industrial revolution was separating economic work from the family home. The 19th century's technological advancements in machinery and manufacturing initiated the separation of work from family. However, it was not until the early 20th century that the first view of work–family theories started to take shape. Structural-functionalism as one of the dominant sociology theories of early 20th century was a natural candidate.\n\nThe structural functionalism theory, which emerged following WWII, was largely influenced from the industrial revolution and the changes in the social role of men and women during this period. This theory implies that the life is concerned mainly with two separate spheres: productive life which happens in the workplace and affective life which is at home. Structural functionalism theory believes in the existence of radical separation between work (institution, workplace, or market) and families. According to this theory, these two (workplace and family) work best \"when men and women specialize their activities in separate spheres, women at home doing expressive work and men in the workplace performing instrumental tasks\" (Kingsbury & Scanzoni, 1993; as cited in MacDermid, 2005: 18).\n\nGreedy institutions\nIt has been argued that the work–family conflicts, in particular role conflicts, can be interpreted in terms of Lewis A. Coser's concept of \"greedy institutions\". These institutions are called \"greedy\" in the sense that they make all-encompassing demands on the commitment and loyalty of individuals, and tend to discourage involvement in other social spheres. Institutions such as religious orders, sects, academia, top level sports, the military and senior management have been interpreted as greedy institutions. On the other hand, also the family has been interpreted as a greedy institution in consideration of the demands placed on a caretaker. When a person is involved in two greedy institutions—be it child care and university, or family and the military, or others—task and role conflicts arise.\n\nSegmentation\nBased on this theory work and family do not affect each other, since they are segmented and independent from each other. The literature also reports the usage of the terms compartmentalization, independence, separateness, disengagement, neutrality, and detachment to describe this theory.\n\nCompensation\nIn 1979, Piotrkowski argued that according to this theory employees \"look to their homes as havens,  look to their families as sources of satisfaction lacking in the occupational sphere.\" What distinguishes compensation theory from the previous theories is that, in compensation theory, for the first time, the positive effect of work to family has been recognized.\n\nSupplemental and reactive compensation\nSupplemental and reactive compensation theories are two dichotomies of compensation theory which were developed during the late 1980s and the early 1990s. While compensation theory describes the behavior of employees in pursuing an alternative reward in the other sphere, supplemental and reactive compensation theories try to describe the reason behind the work–family compensation behavior of employees.\n\nRole enhancement theory\nAccording to this theory, the combination of certain roles has a positive, rather than a negative effect on well-being. This theory states that participation in one role is made better or easier by virtue of participation in the other role. Moreover, this theory acknowledges the negative effect of the work–family relationship, in which, only beyond a certain upper limit may overload and distress occur, however, the central focus of this perspective is mainly on the positive effects of work and family relationship, such as resource enhancement.\n\nWork enrichment model\nThis theory is one of the recent models for explaining the relationship between work and family. According to this model, experience in one role (work or family) will enhance the quality of life in the other role. In other words, this model tries to explain the positive effects of the work–family relationship.",
        "answer": "- Structural Functionalism: The theory of structural functionalism indicates that life is strictly separated between the workplace, where productive life occurs, and home or family life where affective life takes place.\n\n- Greedy Institutions: The theory of greedy institutions posits that institutions make sweeping demands on individuals, and discourage an individual's participation in other social areas or institutions, leading to conflict when competing demands arise.\n\n- Segmentation: The theory of segmentation argues that work and family life are fully segmented or severed from one another and therefore do not affect each other.\n\n-Compensation: The theory of compensation states that individuals find refuge from work and its deficiencies in their home lives and the satisfaction that comes from their families.\n\n-Supplemental and Reactive Compensation: Supplemental and reactive compensation are two theories that describe the ways in which individuals pursue alternative forms of life satisfaction while caught between the work and family social spheres.\n\n- Role enhancement: The theory of role enhancement posits that participation in one social sphere can enhance satisfaction and participation in the other--up to certain limits beyond which overload may occur. \n\n- Work Enrichment Model: The theory of work enrichment attempts to explain how experience in one role or social sphere can complement or increase satisfaction in another. In this way, the work enrichment model is similar to the theory of role enhancement.",

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nAdversarial example generation in NLP (Zhang et al., 2019) is more challenging than in commonly studied computer vision tasks (Szegedy et al., 2014; Kurakin et al., 2017; Papernot et al., 2017) because of (i) the discrete nature of the input space and (ii) the need to ensure semantic coherence with the original text.",

The game was played on February 7, 2021, at Raymond James Stadium in Tampa, Florida, the home stadium of the Buccaneers, marking the first time a team played a Super Bowl in its home stadium. Due to COVID-19 protocols limiting the stadium's seating capacity to 25,000 fans, it was the least-attended Super Bowl.\n\nThe Buccaneers' victory was their second and made them one of two teams, along with the Baltimore Ravens, to be undefeated in multiple Super Bowls. They finished the regular season with an 11–5 record and a wild card berth to advance to their second Super Bowl appearance through the guidance of several new acquisitions, most notably 21-year veteran quarterback Tom Brady in his first season away from the New England Patriots. The Chiefs, aided by their top-ranked offense, finished the regular season with a league-best 14–2 record to advance to their fourth Super Bowl appearance and were the defending Super Bowl LIV champions, seeking to become the first repeat champions since the Patriots in 2004.\n\nFor the first time under quarterback Patrick Mahomes, the Chiefs failed to score a touchdown and lost by double-digits, making them the third Super Bowl team to not score a touchdown. They also committed 11 penalties for 120 yards, including a record eight penalties for 95 yards in the first half, most of which were called against the defense. The Buccaneers capitalized on these struggles to take a commanding 21–6 lead at halftime and dominated the remainder of the game.

Each dataset comes with official textual data to train language models, which contain 37 million tokens for WSJ, 800 million tokens for Librispeech. Our language models are trained separately for each dataset on the official text data only. These datasets were chosen to study the impact of the different components of our system at different scales of training data and in different recording conditions.\nThe models are evaluated in Word Error Rate (WER). Our experiments use the open source codes of wav2letter for the acoustic model, and fairseq for the language model. More details on the experimental setup are given below.\nBaseline Our baseline for each dataset follows BIBREF11 . It uses the same convolutional acoustic model as our approach but a mel-filterbanks front-end and a 4-gram language model.\nTraining/test splits On WSJ, models are trained on si284. nov93dev is used for validation and nov92 for test. On Librispeech, we train on the concatenation of train-clean and train-other. The validation set is dev-clean when testing on test-clean, and dev-other when testing on test-other.\nAcoustic model architecture The architecture for the convolutional acoustic model is the \"high dropout\" model from BIBREF11 for Librispeech, which has 19 layers in addition to the front-end (mel-filterbanks for the baseline, or the learnable front-end for our approach). On WSJ, we use the lighter version used in BIBREF17 , which has 17 layers. Dropout is applied at each layer after the front-end, following BIBREF20 . The learnable front-end uses 40 or 80 filters. Language model architecture As described in Section SECREF8 , we use the GCNN-14B model of BIBREF0 with dropout at each convolutional and linear layer on both WSJ and Librispeech. We keep all the words (162K) in WSJ training corpus. For Librispeech, we only use the most frequent 200K tokens (out of 900K).\nHyperparameter tuning The acoustic models are trained following BIBREF11 , BIBREF17 , using SGD with a decreasing learning rate, weight normalization and gradient clipping at 0.2 and a momentum of 0.9. The language models are trained with Nesterov accelerated gradient BIBREF27 . Following BIBREF0 , we also use weight normalization and gradient clipping.\nThe parameters of the beam search (see Section SECREF9 ) INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are tuned on the validation set with a beam size of 2500 and a beam score of 26 for computational efficiency.

        "question": "What is electrical conduction?",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

        "question": "What is the first scheme assumeing to define cross-lingual document classification?",
        "answer": "The first scheme assumes that the authors have no resources in the transfer language at all, neither labeled nor unlabeled.",
        "evidence": "In this section, we provide comparative results on our new Multilingual Document Classification Corpus. Since the initial work by BIBREF0 many alternative approaches to cross-lingual document classification have been developed. We will encourage the respective authors to evaluate their systems on MLDoc. We believe that a large variety of transfer language pairs will give valuable insights on the performance of the various approaches.\nIn this paper, we propose initial strong baselines which represent two complementary directions of research: one based on the aggregation of multilingual word embeddings, and another one, which directly learns multilingual sentence representations. Details on each approach are given in section \"Multilingual word representations\" and \"Multilingual sentence representations\" respectively. In contrast to previous works on cross-lingual document classification with RVC2, we explore training the classifier on all languages and transfer it to all others, ie. we do not limit our study to the transfer between English and a foreign language.\nOne can envision several ways to define cross-lingual document classification, in function of the resources which are used in the source and transfer language (see Table 3 ). The first scheme assumes that we have no resources in the transfer language at all, neither labeled nor unlabeled. We will name this case “zero-shot cross-lingual document classification”. To simplify the presentation, we will assume that we transfer from English to German. The training and evaluation protocol is as follows. First, train a classifier using resources in the source language only, eg. the training and development corpus are in English. All meta parameters and model choices are performed using the English development corpus. Once the best performing model is selected, it is applied to the transfer language, eg. the German test set. Since no resources of the transfer language are used, the same system can be applied to many different transfer languages. This type of cross-lingual document classification needs a very strong multilingual representation since no knowledge on the target language was used during the development of the classifier.\nIn a second class of cross-lingual document classification, we may aim in improving the transfer performance by using a limited amount of resources in the target language. In the framework of the proposed MLDoc we will use the development corpus of target language for model selection. We will name this method “targeted cross-lingual document classification” since the system is tailored to one particular transfer language. It is unlikely that this system will perform well on other languages than the ones used for training or model selection.\nIf the goal is to build one document classification system for many languages, it may be interesting to use already several languages during training and model selection. To allow a fair comparison, we will assume that these multilingual resources have the same size than the ones used for zero-shot or targeted cross-language document classification, e.g. a training set composed of five languages with 200 examples each. This type of training is not a cross-lingual approach any more. Consequently, we will refer to this method as “joint multilingual document classification”.\nThe first scheme assumes that we have no resources in the transfer language at all, neither labeled nor unlabeled.",

        "evidence": "With the availability of rich data on users' locations, profiles and search history, personalization has become the leading trend in large-scale information retrieval. However, efficiency through personalization is not yet the most suitable model when tackling domain-specific searches. This is due to several factors, such as the lexical and semantic challenges of domain-specific data that often include advanced argumentation and complex contextual information, the higher sparseness of relevant information sources, and the more pronounced lack of similarities between users' searches.\nA recent study on expert search strategies among healthcare information professionals BIBREF0 showed that, for a given search task, they spend an average of 60 minutes per collection or database, 3 minutes to examine the relevance of each document, and 4 hours of total search time. When written in steps, their search strategy spans over 15 lines and can reach up to 105 lines.\nWith the abundance of information sources in the medical domain, consumers are more and more faced with a similar challenge, one that needs dedicated solutions that can adapt to the heterogeneity and specifics of health-related information.\nDedicated Question Answering (QA) systems are one of the viable solutions to this problem as they are designed to understand natural language questions without relying on external information on the users.\nIn the context of QA, the goal of Recognizing Question Entailment (RQE) is to retrieve answers to a premise question ( INLINEFORM0 ) by retrieving inferred or entailed questions, called hypothesis questions ( INLINEFORM1 ) that already have associated answers. Therefore, we define the entailment relation between two questions as: a question INLINEFORM2 entails a question INLINEFORM3 if every answer to INLINEFORM4 is also a correct answer to INLINEFORM5 BIBREF1 .\nRQE is particularly relevant due to the increasing numbers of similar questions posted online BIBREF2 and its ability to solve differently the challenging issues of question understanding and answer extraction. In addition to being used to find relevant answers, these resources can also be used in training models able to recognize inference relations and similarity between questions.\nQuestion similarity has recently attracted international challenges BIBREF3 , BIBREF4 and several research efforts proposing a wide range of approaches, including Logistic Regression, Recurrent Neural Networks (RNNs), Long Short Term Memory cells (LSTMs), and Convolutional Neural Networks (CNNs) BIBREF5 , BIBREF6 , BIBREF1 , BIBREF7 .\nIn this paper, we study question entailment in the medical domain and the effectiveness of the end-to-end RQE-based QA approach by evaluating the relevance of the retrieved answers. Although entailment was attempted in QA before BIBREF8 , BIBREF9 , BIBREF10 , as far as we know, we are the first to introduce and evaluate a full medical question answering approach based on question entailment for free-text questions.

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.",

We are happy to cite any additional theory work that we are missing if you have any pointers.",
        "evidence": "Theoretical Analysis of the DG Setting and Algorithms The DG problem setting was first analysed in. Since then there have been some attempts to analyse DG algorithms from a generalisation bound perspective. However these studies have theoretical results that are either restricted to specific model classes, such as kernel machines, or make strong assumptions about how the domains seen during training will resemble those seen at test time-e.g., that all domains are convex combinations of a finite pre-determined set of prototypical domains. In contrast, our Rademacher complexity approach can be applied to a broad range of model classes (including neural networks), and makes comparatively milder assumptions about the relationship between domains-i.e., they are i.i.d. samples from another arbitrary distribution over domains.\nThe majority of the existing work investigating the theoretical foundations of DG follow the initial formalisation of the domain generalisation problem put forth by, where the goal is to minimise the expected error over unseen domains. However, several recent works have also explored the idea of bounding the error on a single unseen domain with the most pathological distribution shift. This type of analysis is typically rooted in methods from causal inference, rather than statistical learning theory. As a consequence, they are able to make stronger claims for the problems they address, but the scope of their analysis is necessarily limited to the scenarios where their assumptions about the underlying causal structures are valid. For example, Janzing (2019) provides bounds that assume problems conform to a specific class of structural equation models, and the analysis is performed under the assumption that infinite training data is available within each of the observed training domains. Throughout the work we address the stan-dard DG formalisation given by, where one is concerned with the expected performance of a model on domains sampled from some distribution over domains.\nOthers rely on trying to link between domain adaptation objectives (where target domains are observable for alignment to source domains) and domain generalisation (where target domains are not observable and thus cannot correctly be used in a learning objective). proceed by making assumptions on the structure of the distribution over possible domains (i.e., that it has support determined by the convex hull of a finite set of prototypical domains), which allows them to upper bound the domain alignment metric. provide a bound that depends on an unobservable domain distance quantity, which they then approximate in experiments using kernel density estimates. is another piece of work that theoretically investigates the generalisation of ERM in a DG setting. They deal with online DG, where each time-step corresponds to observing a new domain, and the learner must produce a new model capable of generalising to novel domains. Another point of difference between their work and the standard DG problem setting of is that the domain at each time-step is chosen by an adversary. They analyse this game for a finite number of time-steps, but they assume each domain has an infinite amount of data. They also put some limitations on the adversary: e.g., it must choose a domain that is a convex combination of a finite number of pre-determined domains. In contrast, our theoretical analysis is in the more realistic setting where one has a finite amount of data per domain, and the domains we consider are not limited to convex combinations of a set of prototypical domains. Possibly the most similar work to our theoretical contributions is due to, who also provide learningtheoretic generalisation bounds for DG. However, their analysis only applies to finite hypothesis classes (which does not include, e.g., linear models or neural networks), whereas ours can be applied to any class amenable to analysis with Rademacher complexity.\nThe main existing empirical analysis on DG is, who compared several state of the art DG methods under a common evaluation and hyper-parameter tuning protocol called DomainBed. They ultimately defend Empirical Risk Minimization (ERM) over more sophisticated alternatives on the grounds that no competitor consistently beats it across the benchmark suite. We also broadly defend ERM, and build on the same benchmark, but differently we provide a much deeper analysis into when and why ERM works. More specifically: (i) We provide a new theoretical analysis of ERM's generalisation quality unlike the prior purely empirical evaluation, (ii) We re-use the DomainBed benchmark to directly corroborate this theory under controlled conditions using linear models where model complexity can be tractably and accurately tuned. (iii) We use our complexity-based analysis to explain the previously erratic results of prior DomainBed competitors in terms of model complexity. (iv) We identify, and empirically validate, the preferred model selection criterion for DG, a point which was inconclusive in.\nTheoretical Analysis of the DG Setting and Algorithms The DG problem setting was first analysed in Blanchard et al. (2011). Since then there have been some attempts to analyse DG algorithms from a generalisation bound perspective (Muandet et al., 2013; Blanchard et al., 2021; Hu et al., 2020; Albuquerque et al., 2020; Rosenfeld et al., 2021).

        "question": "What do the authors introduce to explore a novel application of CapsNet on triple-based data?",
        "answer": "CapsE.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization.",

        "evidence": "Kubernetes defines a set of building blocks (\"primitives\") that collectively provide mechanisms that deploy, maintain, and scale applications based on CPU, memory or custom metrics. Kubernetes is loosely coupled and extensible to meet different workloads. The internal components as well as extensions and containers that run on Kubernetes rely on the Kubernetes API. The platform exerts its control over compute and storage resources by defining resources as Objects, which can then be managed as such.\n\nKubernetes follows the primary/replica architecture. The components of Kubernetes can be divided into those that manage an individual node and those that are part of the control plane.\n\nControl plane\nThe Kubernetes master node handles the Kubernetes control plane of the cluster, managing its workload and directing communication across the system. The Kubernetes control plane consists of various components, each its own process, that can run both on a single master node or on multiple masters supporting high-availability clusters. The various components of the Kubernetes control plane are as follows:\n\netcd is a persistent, lightweight, distributed, key-value data store that CoreOS has developed. It reliably stores the configuration data of the cluster, representing the overall state of the cluster at any given point of time. etcd favors consistency over availability in the event of a network partition (see CAP theorem). The consistency is crucial for correctly scheduling and operating services.\nThe API server serves the Kubernetes API using JSON over HTTP, which provides both the internal and external interface to Kubernetes. The API server processes and validates REST requests and updates the state of the API objects in etcd, thereby allowing clients to configure workloads and containers across worker nodes. The API server uses etcd's watch API to monitor the cluster, roll out critical configuration changes, or restore any divergences of the state of the cluster back to what the deployer declared. As an example, the deployer may specify that three instances of a particular \"pod\" (see below) need to be running. etcd stores this fact. If the Deployment Controller finds that only two instances are running (conflicting with the etcd declaration), it schedules the creation of an additional instance of that pod.\nThe scheduler is the extensible component that selects on which node an unscheduled pod (the basic entity managed by the scheduler) runs, based on resource availability. The scheduler tracks resource use on each node to ensure that workload is not scheduled in excess of available resources. For this purpose, the scheduler must know the resource requirements, resource availability, and other user-provided constraints or policy directives such as quality-of-service, affinity vs. anti-affinity requirements, and data locality. The scheduler's role is to match resource \"supply\" to workload \"demand\".\nA controller is a reconciliation loop that drives the actual cluster state toward the desired state, communicating with the API server to create, update, and delete the resources it manages (e.g., pods or service endpoints). One kind of controller is a Replication Controller, which handles replication and scaling by running a specified number of copies of a pod across the cluster. It also handles creating replacement pods if the underlying node fails. Other controllers that are part of the core Kubernetes system include a DaemonSet Controller for running exactly one pod on every machine (or some subset of machines), and a Job Controller for running pods that run to completion (e.g., as part of a batch job). Labels selectors that are part of the controller's definition specify the set of pods that a controller manages.\nThe controller manager is a process that manages a set of core Kubernetes controllers.",

The scheduler is a component which selects on which node an unscheduled pod should run, based on what each pod needs and what the nodes in the cluster can support.\n4.

        "evidence": "Distributed representations - dense real-valued vectors that encode the semantics of linguistic units - are ubiquitous in today's NLP research. For single-words or word-like entities, there are established ways to acquire such representations from naturally occurring (unlabelled) training data based on comparatively task-agnostic objectives (such as predicting adjacent words). These methods are well understood empirically BIBREF0 and theoretically BIBREF1 . The best word representation spaces reflect consistently-observed aspects of human conceptual organisation BIBREF2 , and can be added as features to improve the performance of numerous language processing systems BIBREF3 .\nBy contrast, there is comparatively little consensus on the best ways to learn distributed representations of phrases or sentences. With the advent of deeper language processing techniques, it is relatively common for models to represent phrases or sentences as continuous-valued vectors. Examples include machine translation BIBREF8 , image captioning BIBREF9 and dialogue systems BIBREF10 . While it has been observed informally that the internal sentence representations of such models can reflect semantic intuitions BIBREF11 , it is not known which architectures or objectives yield the `best' or most useful representations. Resolving this question could ultimately have a significant impact on language processing systems. Indeed, it is phrases and sentences, rather than individual words, that encode the human-like general world knowledge (or `common sense') BIBREF12 that is a critical missing part of most current language understanding systems.\nWe address this issue with a systematic comparison of cutting-edge methods for learning distributed representations of sentences. We constrain our comparison to methods that do not require labelled data gathered for the purpose of training models, since such methods are more cost-effective and applicable across languages and domains. We also propose two new phrase or sentence representation learning objectives - Sequential Denoising Autoencoders (SDAEs) and FastSent, a sentence-level log-linear bag-of-words model. We compare all methods on two types of task - supervised and unsupervised evaluations - reflecting different ways in which representations are ultimately to be used. In the former setting, a classifier or regression model is applied to representations and trained with task-specific labelled data, while in the latter, representation spaces are directly queried using cosine distance.\nWe observe notable differences in approaches depending on the nature of the evaluation metric. In particular, deeper or more complex models (which require greater time and resources to train) generally perform best in the supervised setting, whereas shallow log-linear models work best on unsupervised benchmarks. Specifically, SkipThought Vectors BIBREF13 perform best on the majority of supervised evaluations, but SDAEs are the top performer on paraphrase identification. In contrast, on the (unsupervised) SICK sentence relatedness benchmark, FastSent, a simple, log-linear variant of the SkipThought objective, performs better than all other models. Interestingly, the method that exhibits strongest performance across both supervised and unsupervised benchmarks is a bag-of-words model trained to compose word embeddings using dictionary definitions BIBREF14 . Taken together, these findings constitute valuable guidelines for the application of phrasal or sentential representation-learning to language understanding systems.\nWe observe notable differences in approaches depending on the nature of the evaluation metric.",

Prior to the deep learning era, these information were used as effective categorical features BIBREF3, BIBREF4, BIBREF5, BIBREF6 for the machine learning model. Recent work has used them to improve the overall performance BIBREF7, BIBREF8, interpretability BIBREF9, BIBREF10, and personalization BIBREF11 of neural network models in different tasks such as sentiment classification BIBREF12, review summarization BIBREF13, and text generation BIBREF8.\nIn particular, user and product information have been widely incorporated in sentiment classification models, especially since they are important metadata attributes found in review websites. BIBREF12 first showed significant accuracy increase of neural models when these information are used. Currently, the accepted standard method is to use them as additional biases when computing the weights $a$ in the attention mechanism, as introduced by BIBREF7 as:\nwhere $u$ and $p$ are the user and product embeddings, and $h$ is a word encoding from BiLSTM. Since then, most of the subsequent work attempted to improve the model by extending the model architecture to be able to utilize external features BIBREF14, handle cold-start entities BIBREF9, and represent user and product separately BIBREF15.\nIntuitively, however, this method is not the ideal method to represent and inject attributes because of two reasons. First, representing attributes as additional biases cannot model the relationship between the text and attributes. Rather, it only adds a user- and product-specific biases that are independent from the text when calculating the attention weights. Second, injecting the attributes in the attention mechanism means that user and product information are only used to customize how the model choose which words to focus on, as also shown empirically in previous work BIBREF7, BIBREF15. However, we argue that there are more intuitive locations to inject the attributes such as when contextualizing words to modify their sentiment intensity.\nWe propose to represent user and product information as weight matrices (i.e., $W$ in the equation above). Directly incorporating these attributes into $W$ leads to large increase in parameters and subsequently makes the model difficult to optimize. To mitigate these problems, we introduce chunk-wise importance weight matrices, which (1) uses a weight matrix smaller than $W$ by a chunk size factor, and (2) transforms these matrix into gates such that it corresponds to the relative importance of each neuron in $W$. We investigate the use of this method when injected to several locations in the base model: word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.\nThe results of our experiments can be summarized in three statements. First, our preliminary experiments show that doing bias-based attribute representation and attention-based injection is not an effective method to incorporate user and product information in sentiment classification models. Second, despite using only a simple BiLSTM with attention classifier, we significantly outperform previous state-of-the-art models that use more complicated architectures (e.g., models that use hierarchical models, external memory networks, etc.). Finally, we show that these attribute representations transfer well to other tasks such as product category classification and review headline generation.\nThus, we use a simple classifier as our base model, which consists of four parts explained briefly as follows.",

However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL.

To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW.

        "evidence": "The third century AD showed some remarkable development for the empire as well as a potential decline and collapse. Emperor Caracalla's edict in 212 AD known as the Antoninian constitution delivered Roman citizenship to every free man in the empire, starting the decline of the importance of the city of Rome and indeed of Roman Italy for the Roman Empire. By the mid-third century AD, Pax Romana had come to an end, and several crises hit the empire simultaneously in a period known to history as the Crisis of the third century. This period saw the empire exposed to rampant inflation, natural disasters, secession and civil wars taking places over several decades. The secessions ended with emperor Aurelian’s conquest of the secessionist Palmyrene Empire and Gallic Empire in 273 and 274 AD, as Aurelian unified a splintered empire which, according to many historians, should have been doomed. However, Aurelian was assassinated in 276 AD, sparking additional civil wars. The crisis came to an end only through the ascension of emperor Diocletian to the throne. The West suffered more heavily from these decades of crisis due to this distinction between the established and more prosperous Hellenised East and the younger colonized and Romanized West that had persisted. This cultural division of the Roman Empire into an eastern Greek and western Latin part became increasingly important in later centuries, leading to a gradual estrangement of the two Roman worlds.\n\nEmperor Diocletian created the administrative system known as the Dominate to guarantee security in all endangered regions of his empire. The dominate was in comparison with the principate, a huge imperial bureaucracy, which laid the foundations for the power structure of the later Eastern Roman Empire. With this came a redistricting and reduction of Roman provinces. Diocletian scrapped any pretense of republican rule as the emperor moved away from formally being merely \"Princeps\" to being \"Dominus\" - Lord and master. Diocletian also formally finished the process of restructuring the empire, from being a colonial-styled empire ruled by Rome and Roman Italians in the first century AD to a larger imperial entity where the emperor's court was not bound to the city of Rome or Italy, now only one Roman imperial province among many. The norm of emperors being Roman Italians was first broken by emperor Trajan who came from Hispania. By the time of the Severan dynasty, most emperors were originating from outside of Italy. When Diocletian introduced his reforms, this had the effect of the Roman Senate formally lost its already declining imperial influence and became a de facto regional body of decision-making.\n\nAn early instance of the partition of the empire into East and West occurred in 286, when Emperor Diocletian appointed Maximian as augustus of the West. In 293 AD, the empire went through a devolution under Diocletian known as the Tetrarchy. The empire was split into four, with the two most prominent parts of the empire each ruled by one emperor (Augustus). Each co-emperor then appointed a young colleague as caesar to be a subordinate emperor with control over his own territory. The Caesar shared power with and would eventually succeed the senior partner. Each tetrarch was in charge of a part of the empire, with the divisions based on geographic regions. This devolution outlines the coming split 100 years later when the empire was permanently divided into an eastern and western empire. The tetrarchy however only lasted 20 years, as emperors quickly began fighting each other for power. The whole empire was eventually reunited by Constantine the Great in 324 after he ended the last of these civil wars.",

        "evidence": "Suppose a user wants to write a sentence “I will be 10 minutes late.” Ideally, she would type just a few keywords such as “10 minutes late” and an autocomplete system would be able to infer the intended sentence (Figure FIGREF1). Existing left-to-right autocomplete systems BIBREF0, BIBREF1 can often be inefficient, as the prefix of a sentence (e.g. “I will be”) fails to capture the core meaning of the sentence. Besides the practical goal of building a better autocomplete system, we are interested in exploring the tradeoffs inherent to such communication schemes between the efficiency of typing keywords, accuracy of reconstruction, and interpretability of keywords.\nOne approach to learn such schemes is to collect a supervised dataset of keywords-sentence pairs as a training set, but (i) it would be expensive to collect such data from users, and (ii) a static dataset would not capture a real user's natural predilection to adapt to the system BIBREF2. Another approach is to avoid supervision and jointly learn a user-system communication scheme to directly optimize the combination of efficiency and accuracy. However, learning in this way can lead to communication schemes that are uninterpretable to humans BIBREF3, BIBREF4 (see Appendix for additional related work).\nIn this work, we propose a simple, unsupervised approach to an autocomplete system that is efficient, accurate, and interpretable. For interpretability, we restrict keywords to be subsequences of their source sentences based on the intuition that humans can infer most of the original meaning from a few keywords. We then apply multi-objective optimization approaches to directly control and achieve desirable tradeoffs between efficiency and accuracy.\nWe observe that naively optimizing a linear combination of efficiency and accuracy terms is unstable and leads to suboptimal schemes. Thus, we propose a new objective which optimizes for communication efficiency under an accuracy constraint. We show this new objective is more stable and efficient than the linear objective at all accuracy levels.\nAs a proof-of-concept, we build an autocomplete system within this framework which allows a user to write sentences by specifying keywords. We empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences. Finally, we demonstrate that humans can easily adapt to the keyword-based autocomplete system and save nearly 50% of time compared to typing a full sentence in our user study.\nWe empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences.",

        "answer": "Traveling alone to anywhere in the world can be very intimidating and cal also feel lonely at times, but the great news is that it's extremely easy to make friends abroad! A couple of ways to make friends are: \n1. Visit your neighborhood bar and sit at the bar. More than likely there will be other folks going alone and you'll be able to chat with them. You can strike a conversation by easily asking them about their order or if they're from the area. \n2. Join travel groups on Facebook, Instagram and TikTok. With social media, it's much easier to find people who are traveling in the same location as you are and willing to meet up. A great group is The Travel Squad. You can join their Facebook community with thousands of solo travelers \n3. Do walking tours! There are a ton of free walking tours that you can do so make sure to sign up. \n4. Excursions is another great way to meet others. Don't be afraid to ask people where they are from or what got them interested in doing that excursion. \n5. Hostels. If you don't mind the noise levels, hostels are one of the top ways to meet fellow friends while solo traveling. They always host great music, events and have a common dining room area where people tend to hang out. \n\nTraveling alone can feel scary but remember that all it takes is getting out of your comfort zone and striking up a conversation to make long lasting friendships!",

        "question": "Based on the following paragraph on squat lobster fisheries, where do such fisheries exist today?",
        "evidence": "Flesh from these animals is often commercially sold in restaurants as \"langostino\" or sometimes dishonestly called \"lobster\" when incorporated in seafood dishes. As well as being used for human consumption, there is demand for squat lobster meat to be used as feed in fish farms and shrimp or prawn farms. This is in part because they contain astaxanthin, a pigment that helps to colour the meat of farmed salmon and trout.\nDespite their worldwide distribution and great abundance, there are few functioning fisheries for squat lobsters. Experimental fisheries have occurred in several countries, including Argentina, Mexico, and New Zealand, but commercial exploitation is currently restricted to Latin America, and chiefly to Chile. The main target species are Pleuroncodes monodon, P. planipes, and Cervimunida johni.\nIn Central America, the primary species of squat lobster targeted by fisheries is a species of Pleuroncodes. There is a great deal of confusion over both scientific names and common names, and the exact species is often unknown. In El Salvador, for instance, the commercial catch is generally referred to as \"P. planipes\", but is in fact P. monodon. Commercial fishing for squat lobsters in El Salvador began in the early 1980s; production increased markedly in the 2001 season, and has continued to grow, now making up 98% of the demersal resources landed in El Salvador, with annual catches peaking at 13,708 t in 2005. In Costa Rica, aggregations of squat lobsters are avoided, as the fishermen fear the squat lobsters will clog their nets. In Nicaragua, squat lobsters are heavily exploited, especially following a large increase in fishing effort in the 2007 season. In Panama, production reached 492 t in 2008. Chilean squat lobster fisheries initially targeted Cervimunida johni, beginning in 1953. By the mid-1960s, effort had largely switched to P. monodon. In an effort to conserve stocks, the Chilean government instituted quotas for squat lobsters, and the fishery is closely monitored. In New Zealand, Munida gregaria has been considered as a potential fisheries resource, particularly to feed farmed Chinook salmon (Oncorhynchus tshawytscha).",

        "question": "In his dataset coding process, what techniques does he use?",
        "answer": "An abundance of online news content, and other technical advances made possible by open-source software.",
        "evidence": "Automated coding of political event data, or the record of who-did-what-to-whom within the context of political actions, has existed for roughly two decades. The approach has remained largely the same during this time, with the underlying coding procedures not updating to reflect changes in natural language processing (NLP) technology. These NLP technologies have now advanced to such a level, and with accompanying open-source software implementations, that their inclusion in the event-data coding process comes as an obvious advancement. When combined with changes in how news content is obtained, the ability to store and process large amounts of text, and enhancements based on two decades worth of event-data experience, it becomes clear that political event data is ready for a next generation dataset.\nIn this chapter, I provide the technical details for creating such a next-generation dataset. The technical details lead to a pipeline for the production of the Phoenix event dataset. The Phoenix dataset is a daily updated, near-real-time political event dataset. The coding process makes use of open-source NLP software, an abundance of online news content, and other technical advances made possible by open-source software. This enables a dataset that is transparent and replicable, while providing a more accurate coding process than previously possible. Additionally, the dataset's near-real-time nature also enables many applications that were previously impossible with batch-updated datasets, such as monitoring of ongoing events. Thus, this dataset provides a significant improvement over previous event data generation efforts.\nIn the following sections I briefly outline the history of computer-generated political event data to this point in history. I then outline what the “next generation” of event data should look like. Following this, I discuss the many facets of creating a real-time political event dataset, mainly from a technological and infrastructure standpoint. Finally, the paper concludes with a brief empirical view of the Phoenix event dataset, which is the output of the previously-discussed technological pipeline.\nPhoenix dataset is a daily updated, nearreal-time political event dataset.

        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nWe show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models (Lebret et al., 2016; Mei et al., 2016) on this dataset.",

        "evidence": "To estimate the quality of topic models in a real task, we chose Islam informational portal \"Golos Islama\" (Islam Voice) (in Russian). This portal contains both news articles related to Islam and articles discussing Islam basics. We supposed that the thematic analysis of this specialized site can be significantly improved with domain-specific knowledge described in the thesaurus form. We extracted the site contents using Open Web Spider and obtained 26,839 pages.\nTo combine knowledge with a topic model, we used RuThes thesaurus together with the additional block of the Islam thesaurus. The Islam thesaurus contains more than 5 thousand Islam-related terms including single words and expressions.\nFor each combined model, we ran two experiments with 100 topics and with 200 topics. The generated topics were evaluated by two linguists, who had previously worked on the Islam thesaurus. The evaluation task was formulated as follows: the experts should read the top elements of the generated topics and try to formulate labels of these topics. The labels should be different for each topic in the set generated with a specific model. The experts should also assign scores to the topics' labels:\nThen we can sum up all the scores for each model under consideration and compare the total scores in value. Thus, maximum values of the topic score are 200 for a 100-topic model and 400 for a 200-topic model. In this experiment we do not measure inter-annotator agreement for each topic, but try to get expert's general impression.\nDue to the complicated character of the Islam portal contents for automatic extraction (numerous words and names difficult for Russian morphological analyzers), we did not use automatic extraction of multiword expressions and exploited only phrases described in RuThes or in the Islam Thesaurus. We added thesaurus phrases in two ways: most frequent 1000 phrases (as in BIBREF14 , BIBREF16 ) and phrases with frequency more than 10 (More10phrases): the number of such phrases is 9351.\nThe results of the evaluation are shown in Table 5. The table contains the overall expert scores for a topic model (Score), kernel uniqueness as in the previous section (KernU), perplexity (Prpl). Also for each model kernels, we calculated the average number of known relations between topics’s elements: thesaurus relations (synonyms and direct relations between concepts) and component-based relations between phrases (Relc).\nIt can be seen that if we add phrases without accounting component similarity (Runs 2, 3), the quality of topics decreases: the more phrases are added, the more the quality degrades. The human scores also confirm this fact. But if the similarity between phrase components is considered then the quality of topics significantly improves and becomes better than for unigram models (Runs 4, 5). All measures are better. Relational coherence between kernel elements also grows. The number of added phrases is not very essential.\nAdding unary synonyms decreases the quality of the models (Run 6) according to human scores. But all other measures behave differently: kernel uniqueness is high, perplexity decreases, relational coherence grows. The problem of this model is in that non-topical, general words are grouped together, reinforce one another but do not look as related to any topic. Adding all thesaurus relations is not very beneficial (Runs 7, 8). If we consider all relations except hyponyms, the human scores are better for corresponding runs (Runs 9, 10). Relational coherence in topics’ kernels achieves very high values: the quarter of all elements have some relations between each other, but it does not help to improve topics. The explanation is the same: general words can be grouped together.\nAt last, we removed General Lexicon concepts from the RuThes data, which are top-level, non-thematic concepts that can be met in arbitrary domains BIBREF19 and considered all-relations and without-hyponyms variants (Runs 11, 12). These last variants achieved maximal human scores because they add thematic knowledge and avoid general knowledge, which can distort topics. Kernel uniqueness is also maximal.\nTable 6 shows similar topics obtained with the unigram, phrase-enriched (Run 5) and the thesaurus-enriched topic model (Run 12). The Run-5 model adds thesaurus phrases with frequency more than 10 and accounts for the component similarity between phrases. The Run-12 model accounts both component relations and hypernym thesaurus relations. All topics are of high quality, quite understandable. The experts evaluated them with the same high scores.\nPhrase-enriched and thesaurus-enriched topics convey the content using both single words and phrases. It can be seen that phrase-enriched topics contain more phrases. Sometimes the phrases can create not very convincing relations such as Russian church - Russian language. It is explainable but does not seem much topical in this case.\nThe thesaurus topics seem to convey the contents in the most concentrated way. In the Syrian topic general word country is absent; instead of UN (United Nations), it contains word rebel, which is closer to the Syrian situation. In the Orthodox church topic, the unigram variant contains extra word year, relations of words Moscow and Kirill to other words in the topic can be inferred only from the encyclopedic knowledge.\nThe problem of this model is in that non-topical, general words are grouped together, reinforce one another but do not look as related to any topic. Adding all thesaurus relations is not very beneficial (Runs 7, 8).",

        "question": "Summarize Romania's history and founding.",
        "evidence": "Settlement in what is now Romania began in the Lower Paleolithic followed by written records attesting the kingdom of Dacia, its conquest, and subsequent Romanization by the Roman Empire during late antiquity. The modern Romanian state was formed in 1859 through a personal union of the Danubian Principalities of Moldavia and Wallachia. The new state, officially named Romania since 1866, gained independence from the Ottoman Empire in 1877. During World War I, after declaring its neutrality in 1914, Romania fought together with the Allied Powers from 1916. In the aftermath of the war, Bukovina, Bessarabia, Transylvania, and parts of Banat, Crișana, and Maramureș became part of the Kingdom of Romania. In June–August 1940, as a consequence of the Molotov–Ribbentrop Pact and Second Vienna Award, Romania was compelled to cede Bessarabia and Northern Bukovina to the Soviet Union and Northern Transylvania to Hungary. In November 1940, Romania signed the Tripartite Pact and, consequently, in June 1941 entered World War II on the Axis side, fighting against the Soviet Union until August 1944, when it joined the Allies and recovered Northern Transylvania. Following the war and occupation by the Red Army, Romania became a socialist republic and a member of the Warsaw Pact. After the 1989 Revolution, Romania began a transition towards democracy and a market economy.",

        "answer": "Sentences that discuss strengths (class STRENGTH), weaknesses of employees (class WEAKNESS) and suggestions for improving her performance (class SUGGESTION).",
        "evidence": "The PA corpus contains several classes of sentences that are of interest. In this paper, we focus on three important classes of sentences viz., sentences that discuss strengths (class STRENGTH), weaknesses of employees (class WEAKNESS) and suggestions for improving her performance (class SUGGESTION). The strengths or weaknesses are mostly about the performance in work carried out, but sometimes they can be about the working style or other personal qualities. The classes WEAKNESS and SUGGESTION are somewhat overlapping; e.g., a suggestion may address a perceived weakness. Following are two example sentences in each class.\nSTRENGTH:\nWEAKNESS:\nSUGGESTION:\nSeveral linguistic aspects of these classes of sentences are apparent. The subject is implicit in many sentences. The strengths are often mentioned as either noun phrases (NP) with positive adjectives (Excellent technology leadership) or positive nouns (engineering strength) or through verbs with positive polarity (dedicated) or as verb phrases containing positive adjectives (delivers innovative solutions). Similarly for weaknesses, where negation is more frequently used (presentations are not his forte), or alternatively, the polarities of verbs (avoid) or adjectives (poor) tend to be negative. However, sometimes the form of both the strengths and weaknesses is the same, typically a stand-alone sentiment-neutral NP, making it difficult to distinguish between them; e.g., adherence to timing or timely closure. Suggestions often have an imperative mood and contain secondary verbs such as need to, should, has to. Suggestions are sometimes expressed using comparatives (better process compliance). We built a simple set of patterns for each of the 3 classes on the POS-tagged form of the sentences. We use each set of these patterns as an unsupervised sentence classifier for that class. If a particular sentence matched with patterns for multiple classes, then we have simple tie-breaking rules for picking the final class. The pattern for the STRENGTH class looks for the presence of positive words / phrases like takes ownership, excellent, hard working, commitment, etc. Similarly, the pattern for the WEAKNESS class looks for the presence of negative words / phrases like lacking, diffident, slow learner, less focused, etc. The SUGGESTION pattern not only looks for keywords like should, needs to but also for POS based pattern like “a verb in the base form (VB) in the beginning of a sentence”.\nWe randomly selected 2000 sentences from the supervisor assessment corpus and manually tagged them (dataset D1). This labelled dataset contained 705, 103, 822 and 370 sentences having the class labels STRENGTH, WEAKNESS, SUGGESTION or OTHER respectively. We trained several multi-class classifiers on this dataset. Table TABREF10 shows the results of 5-fold cross-validation experiments on dataset D1. For the first 5 classifiers, we used their implementation from the SciKit Learn library in Python (scikit-learn.org). The features used for these classifiers were simply the sentence words along with their frequencies. For the last 2 classifiers (in Table TABREF10 ), we used our own implementation. The overall accuracy for a classifier is defined as INLINEFORM0 , where the denominator is 2000 for dataset D1. Note that the pattern-based approach is unsupervised i.e., it did not use any training data. Hence, the results shown for it are for the entire dataset and not based on cross-validation.\nThe PA corpus contains several classes of sentences that are of interest. In this paper, we focus on three important classes of sentences viz., sentences that discuss strengths (class STRENGTH), weaknesses of employees (class WEAKNESS) and suggestions for improving her performance (class SUGGESTION).",

It is important that oral hygiene be carried out on a regular basis to enable prevention of dental disease and bad breath. The most common types of dental disease are tooth decay (cavities, dental caries) and gum diseases, including gingivitis, and periodontitis.\nGeneral guidelines for adults suggest brushing at least twice a day with a fluoridated toothpaste: brushing last thing at night and at least on one other occasion. Cleaning between the teeth is called interdental cleaning and is as important as tooth brushing. This is because a toothbrush cannot reach between the teeth and therefore only removes about 50% of plaque from the surface of the teeth. There are many tools to clean between the teeth, including floss, tape and interdental brushes; it is up to each individual to choose which tool they prefer to use.",

        "evidence": "The training objective with adversarial neural network is different from the baseline model, as it includes the extra worker discriminator. Thus the new objective includes two parts, one being the negative log-likelihood from NER which is the same as the baseline, and the other being the negative the log-likelihood from the worker discriminator.\nIn order to obtain the negative log-likelihood of the worker discriminator, we use softmax to compute the probability of the actual worker $\\bar{z}$ as well, which is defined by: \n$$p(\\bar{z}|\\mathbf {X}, \\mathbf {\\bar{y}}) = \\frac{\\exp (\\mathbf {o}^{\\text{worker}}_{\\bar{z}})}{\\sum _{z} \\exp (\\mathbf {o}^{\\text{worker}}_z)},$$   (Eq. 22) \nwhere $z$ should enumerate all workers.\nBased on the above definition of probability, our new objective is defined as follows: \n$$\\begin{split}\n\\text{R}(\\Theta , \\Theta ^{\\prime }, \\mathbf {X}, \\mathbf {\\bar{y}}, \\bar{z}) &= \\text{loss}(\\Theta , \\mathbf {X}, \\mathbf {\\bar{y}}) - \\text{loss}(\\Theta , \\Theta ^{\\prime }, \\mathbf {X}) \\\\\n\\text{~~~~~~} &= -\\log p(\\mathbf {\\bar{y}}|\\mathbf {X}) + \\log p(\\bar{z}|\\mathbf {X}, \\mathbf {\\bar{y}}),\n\\end{split}$$   (Eq. 23) \nwhere $\\Theta $ is the set of all model parameters related to NER, and $\\Theta ^{\\prime }$ is the set of the remaining parameters which are only related to the worker discriminator, $\\mathbf {X}$ , $\\mathbf {\\bar{y}}$ and $\\bar{z}$ are the input sentence, the crowd-annotated NE labels and the corresponding annotator for this annotation, respectively. It is worth noting that the parameters of the common Bi-LSTM are included in the set of $\\Theta $ by definition.\nIn particular, our goal is not to simply minimize the new objective. Actually, we aim for a saddle point, finding the parameters $\\Theta $ and $\\Theta ^{\\prime }$ satisfying the following conditions: \n$$\\begin{split}\n\\hat{\\Theta } &= \\mathop {arg~min}_{\\Theta }\\text{R}(\\Theta , \\Theta ^{\\prime }, \\mathbf {X}, \\mathbf {\\bar{y}}, \\bar{z}) \\\\\n\\hat{\\Theta }^{\\prime } &= \\mathop {arg~max}_{\\Theta ^{\\prime }}\\text{R}(\\hat{\\Theta }, \\Theta ^{\\prime }, \\mathbf {X}, \\mathbf {\\bar{y}}, \\bar{z}) \\\\\n\\end{split}$$   (Eq. 24) \nwhere the first equation aims to find one $\\Theta $ that minimizes our new objective $\\text{R}(\\cdot )$ , and the second equation aims to find one $\\Theta ^{\\prime }$ maximizing the same objective.\nIntuitively, the first equation of Formula 24 tries to minimize the NER loss, but at the same time maximize the worker discriminator loss by the shared parameters of the common Bi-LSTM. Thus the resulting features of common Bi-LSTM actually attempt to hurt the worker discriminator, which makes these features worker independent since they are unable to distinguish different workers. The second equation tries to minimize the worker discriminator loss by its own parameter $\\Theta ^{\\prime }$ .\nWe use the standard back-propagation method to train the model parameters, the same as the baseline model. In order to incorporate the term of the argmax part of Formula 24 , we follow the previous work of adversarial training BIBREF13 , BIBREF15 , BIBREF17 , by introducing a gradient reverse layer between the common Bi-LSTM and the CNN module, whose forward does nothing but the backward simply negates the gradients.\nThus the new objective includes two parts, one being the negative log-likelihood from NER which is the same as the baseline, and the other being the negative the log-likelihood from the worker discriminator.",

We observe that our model greatly benefits from the DAE objective for the zero-shot Chinese question generation task. The results also demonstrate that combining DAE and XAE can alleviate the spurious correlation issue and improves cross-lingual NLG.\nAs shown in Table TABREF41, we use the En-En-QG and Zh-Zh-QG tasks to analyze the effects of using different fine-tuning strategies. It can be observed that fine-tuning encoder parameters, our model obtain an impressive performance for both English and Chinese QG, which shows the strong cross-lingual transfer ability of our model. When fine-tuning all the parameters, the model achieves the best score for English QG, but it suffers a performance drop when evaluating on Chinese QG. We find that fine-tuning decoder hurts cross-lingual decoding, and the model learns to only decodes English words. For only fine-tuning decoder, the performance degrades by a large margin for both languages because of the underfitting issue, which indicates the necessity of fine-tuning encoder.\nWe examine whether low-resource NLG can benefit from cross-lingual transfer. We consider English as the rich-resource language, and conduct experiments for few-shot French/Chinese AS. Specifically, we first fine-tune Xnlg on the English AS data, and then fine-tune it on the French or Chinese AS data. We compare with the monolingual supervised model that Xnlg is only fine-tuned on the dataset of the target language. As shown in Figure FIGREF49, we can observe that the cross-lingual supervision improves performance for few-shot abstractive summarization. As the training data size becomes larger, the performance of two models is getting closer.\nIn terms of the pipeline model, we can observe that it suffers from the error propagation issue, especially when the source and target languages are all different from the training data",

        "evidence": "The ability for a machine to converse with human in a natural and coherent manner is one of challenging goals in AI and natural language understanding. One problem in chat-oriented human-machine dialog system is to reply a message within conversation contexts. Existing methods can be divided into two categories: retrieval-based methods BIBREF0 , BIBREF1 , BIBREF2 and generation based methods BIBREF3 . The former is to rank a list of candidates and select a good response. For the latter, encoder-decoder framework BIBREF3 or statistical translation method BIBREF4 are usually used to generate a response. It is not easy to main the fluency of the generated texts.\nUbuntu dialogue corpus BIBREF5 is the public largest unstructured multi-turns dialogue corpus which consists of about one-million two-person conversations. The size of the corpus makes it attractive for the exploration of deep neural network modeling in the context of dialogue systems. Most deep neural networks use word embedding as the first layer. They either use fixed pre-trained word embedding vectors generated on a large text corpus or learn word embedding for the specific task. The former is lack of flexibility of domain adaptation. The latter requires a very large training corpus and significantly increases model training time. Word out-of-vocabulary issue occurs for both cases. Ubuntu dialogue corpus also contains many technical words (e.g. “ctrl+alt+f1\", “/dev/sdb1\"). The ubuntu corpus (V2) contains 823057 unique tokens whereas only 22% tokens occur in the pre-built GloVe word vectors. Although character-level representation which models sub-word morphologies can alleviate this problem to some extent BIBREF6 , BIBREF7 , BIBREF8 , character-level representation still have limitations: learn only morphological and orthographic similarity, other than semantic similarity (e.g. `car' and `bmw') and it cannot be applied to Asian languages (e.g. Chinese characters).\nIn this paper, we generate word embedding vectors on the training corpus based on word2vec BIBREF9 . Then we propose an algorithm to combine the generated one with the pre-trained word embedding vectors on a large general text corpus based on vector concatenation. The new word representation maintains information learned from both general text corpus and task-domain. The nice property of the algorithm is simplicity and little extra computational cost will be added. It can address word out-of-vocabulary issue effectively. This method can be applied to most NLP deep neural network models and is language-independent. We integrated our methods with ESIM(baseline model) BIBREF10 . The experimental results have shown that the proposed method has significantly improved the performance of original ESIM model and obtained state-of-the-art results on both Ubuntu Dialogue Corpus and Douban Conversation Corpus BIBREF11 . On Ubuntu Dialogue Corpus (V2), the improvement to the previous best baseline model (single) on INLINEFORM0 is 3.8% and our ensemble model on INLINEFORM1 is 75.9%. On Douban Conversation Corpus, the improvement to the previous best model (single) on INLINEFORM2 is 3.6%.\nOur contributions in this paper are summarized below:\nThe rest paper is organized as follows. In Section SECREF2 , we review the related work. In Section SECREF3 we provide an overview of ESIM (baseline) model and describe our methods to address out-of-vocabulary issues. In Section SECREF4 , we conduct extensive experiments to show the effectiveness of the proposed method. Finally we conclude with remarks and summarize our findings and outline future research directions.\nThen we propose an algorithm to combine the generated one with the pre-trained word embedding vectors on a large general text corpus based on vector concatenation.",

        "answer": "It consists of weighting pruning, matrix factorization and knowledge distillation.",
        "evidence": "The pre-trained language model, BERT BIBREF0 has led to a big breakthrough in various kinds of natural language understanding tasks. Ideally, people can start from a pre-trained BERT checkpoint and fine-tune it on a specific downstream task. However, the original BERT models are memory-exhaustive and latency-prohibitive to be served in embedded devices or CPU-based online environments. As the memory and latency constraints vary in different scenarios, the pre-trained BERT model should be adaptive to different requirements with accuracy retained to the largest extent. Existing BERT-oriented model compression solutions largely depend on knowledge distillation BIBREF1, which is inefficient and resource-consuming because a large training corpus is required to learn the behaviors of a teacher. For example, DistilBERT BIBREF2 is re-trained on the same corpus as pre-training a vanilla BERT from scratch; and TinyBERT BIBREF3 utilizes expensive data augmentation to fit the distillation target. The costs of these model compression methods are as large as pre-training and unaffordable for low-resource settings. Therefore, it is straight-forward to ask, can we design a lightweight method to generate adaptive models with comparable accuracy using significantly less time and resource consumption? In this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions. Specifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation. Initially, the architecture and weights of student model are inherited from the BERT teacher. In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation. Because weight pruning and matrix factorization help to generate better initial and intermediate status\nin the knowledge distillation iterations, the accuracy and efficiency of model compression can be greatly improved.\nWe conduct extensive experiments on five public datasets of natural language understanding. As an example, the performance comparison of LadaBERT and state-of-the-art models on MNLI-m dataset is illustrated in Figure FIGREF1. We can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios. Especially, LadaBERT-1 outperforms BERT-PKD significantly under $2.5\\times $ compression ratio, and LadaBERT-3 outperforms TinyBERT under $7.5\\times $ compression ratio while the training speed is accelerated by an order of magnitude.\nThe rest of this paper is organized as follows. First, we summarizes the related works of model compression and their applications to BERT in Section SECREF2. Then, the methodology of LadaBERT is introduced in Section SECREF3, and experimental results are presented in Section SECREF4. At last, we conclude this work and discuss future works in Section SECREF5.\nSpecifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation.",

        "question": "How do they control the quality of their pilot study?",
        "answer": "They only employ the US workers with an approval rate of at least 95% and the worst of them are removed. They also set trap sentences in around 80 of the tasks.",
        "evidence": "To verify the proposed approach, we conducted a pilot study on Amazon Mechanical Turk using data from TAC2008 BIBREF36 . We collected importance estimates for 474 propositions extracted from the first three clusters using both task designs. Each Likert-scale task was assigned to 5 different workers and awarded $0.06. For comparison tasks, we also collected 5 labels each, paid $0.05 and sampled around 7% of all possible pairs. We submitted them in batches of 100 pairs and selected pairs for subsequent batches based on the confidence of the TrueSkill model.\nFollowing the observations of Lloret.2013, we established several measures for quality control. First, we restricted our tasks to workers from the US with an approval rate of at least 95%. Second, we identified low quality workers by measuring the correlation of each worker's Likert-scores with the average of the other four scores. The worst workers (at most 5% of all labels) were removed.\nIn addition, we included trap sentences, similar as in BIBREF13 , in around 80 of the tasks. In contrast to Lloret et al.'s findings, both an obvious trap sentence (This sentence is not important) and a less obvious but unimportant one (Barack Obama graduated from Harvard Law) were consistently labeled as unimportant (1.08 and 1.14), indicating that the workers did the task properly.\nFor Likert-scale tasks, we follow Snow.2008 and calculate agreement as the average Pearson correlation of a worker's Likert-score with the average score of the remaining workers. This measure is less strict than exact label agreement and can account for close labels and high- or low-scoring workers. We observe a correlation of 0.81, indicating substantial agreement. For comparisons, the majority agreement is 0.73. To further examine the reliability of the collected data, we followed the approach of Kiritchenko.2016 and simply repeated the crowdsourcing for one of the three topics. Between the importance estimates calculated from the first and second run, we found a Pearson correlation of 0.82 (Spearman 0.78) for Likert-scale tasks and 0.69 (Spearman 0.66) for comparison tasks. This shows that the approach, despite the subjectiveness of the task, allows us to collect reliable annotations.\nIn addition to the reliability studies, we extrinsically evaluated the annotations in the task of summary evaluation. For each of the 58 peer summaries in TAC2008, we calculated a score as the sum of the importance estimates of the propositions it contains. Table TABREF13 shows how these peer scores, averaged over the three topics, correlate with the manual responsiveness scores assigned during TAC in comparison to ROUGE-2 and Pyramid scores. The results demonstrate that with both task designs, we obtain importance annotations that are similarly useful for summary evaluation as pyramid annotations or gold-standard summaries (used for ROUGE).\nBased on the pilot study, we conclude that the proposed crowdsourcing scheme allows us to obtain proper importance annotations for propositions. As workers are not required to read all documents, the annotation is much more efficient and scalable as with traditional methods.\nFollowing the observations of Lloret et al. (2013), we established several measures for quality control. First, we restricted our tasks to workers from the US with an approval rate of at least 95%.

        "question": "What do they present the insertion-deletion framework as?",
        "answer": "A proof of concept.",
        "evidence": "Neural sequence models BIBREF0, BIBREF1 typically generate outputs in an autoregressive left-to-right manner. These models have been successfully applied to a range of task, for example machine translation BIBREF2. They often rely on an encoder that processes the source sequence, and a decoder that generates the output sequence conditioned on the output of the encoder. The decoder will typically generate the target sequence one token at a time, in an autoregressive left-to-right fashion.\nRecently, research in insertion-based non- or partially- autoregressive models has spiked BIBREF3, BIBREF4, BIBREF5, BIBREF6. These model are more flexible than their autoregressive counterparts. They can generate sequences in any order, and can benefit from parallel token generation. They can learn complex orderings (e.g., tree orderings) and may be more applicable to task like cloze question answering BIBREF6 and text simplification, where the order of generation is not naturally left to right, and the source sequence might not be fully observed. One recently proposed approach is the Insertion Transformer BIBREF3, where the target sequence is modelled with insertion-edits. As opposed to traditional sequence-to-sequence models, the Insertion Transformer can generate sequences in any arbitrary order, where left-to-right is a special case. Additionally, during inference, the model is endowed with parallel token generation capabilities. The Insertion Transformer can be trained to follow a soft balanced binary tree order, thus allowing the model to generate $n$ tokens in $O(\\log _2 n)$ iterations.\nIn this work we propose to generalize this insertion-based framework, we present a framework which emits both insertions and deletions. Our Insertion-Deletion Transformer consists of an insertion phase and a deletion phase that are executed iteratively. The insertion phase follows the typical insertion-based framework BIBREF3. However, in the deletion phase, we teach the model to do deletions with on-policy training. We sample an input sequence on-policy from the insertion model (with on-policy insertion errors), and teach the deletion model its appropriate deletions.\nThis insertion-deletion framework allows for flexible sequence generation, parallel token generation and text editing. In a conventional insertion-based model, if the model makes a mistake during generation, this cannot be undone. Introducing the deletion phase makes it possible to undo the mistakes made by the insertion model, since it is trained on the on-policy errors of the insertion phase. The deletion model extension also enables the framework to efficiently handle tasks like text simplification and style transfer by starting the decoding process from the original source sequence.\nA concurrent work was recently proposed, called the Levenshtein Transformer (LevT) BIBREF7. The LevT framework also generates sequences with insertion and deletion operations. Our approach has some important distinctions and can be seen as a simplified version, for both the architecture and the training algorithm. The training algorithm used in the LevT framework uses an expert policy. This expert policy requires dynamic programming to minimize Levenshtein distance between the current input and the target. This approach was also explored by BIBREF8, BIBREF9. Their learning algorithm arguably adds more complexity than needed over the simple on-policy method we propose. The LevT framework consists of three stages, first the number of tokens to be inserted is predicted, then the actual tokens are predicted, and finally the deletion actions are emitted. The extra classifier to predict the number of tokens needed to be inserted adds an additional Transformer pass to each generation step. In practice, it is also unclear whether the LevT exhibits speedups over an insertion-based model following a balanced binary tree order. In contrast, our Insertion-Deletion framework only has one insertion phase and one deletion phase, without the need to predict the number of tokens needed to be inserted. This greatly simplifies the model architecture, training procedure and inference runtime.\nAn alternative approach for text editing is proposed by BIBREF10, which they dub Deliberation Networks. This work also acknowledges the potential benefits from post-editing output sequences and proposes a two-phase decoding framework to facilitate this.\nIn this paper, we present the insertion-deletion framework as a proof of concept by applying it to two synthetic character-based translation tasks and showing it can significantly increase the BLEU score over the insertion-only framework.\nIn this paper, we present the insertion-deletion framework as a proof of concept by applying it to two synthetic character-based translation tasks and showing it can significantly increase the BLEU score over the insertion-only framework.",

        "answer": "The model used for translation is the one implemented by Bahdanau et al. (2014).",
        "evidence": "The model used for translation is the one implemented by Bahdanau et al. Bahdanau2014. A bidirectional LSTM encoder first takes the source sentence and encodes it into a context vector which acts as input for the decoder. The decoder is attention-based where the hidden states of the decoder get as input the weighted sum of all the hidden layer outputs of the encoder alongwith the output of the previous hidden layer and the previously decoded word. This provides a contextual reference into the source language sentence BIBREF4 .\nNeural Machine Translation models directly compute the probability of the target language sentence given the source language sentence, word by word for every time step. The model with a basic decoder without the attention module computes the log probability of target sentence given source sentence as the sum of log probabilities of every word given every word before that. The attention-based model, on the other hand, calculates: DISPLAYFORM0 \nwhere INLINEFORM0 is the number of words in the target sentence, INLINEFORM1 is the target sentence, INLINEFORM2 is the source sentence, INLINEFORM3 is the fixed length output vector of the encoder and INLINEFORM4 is the weighted sum of all the hidden layer outputs of the encoder at every time step. Both the encoder's output context vector and the weighted sum (known as attention vector) help to improve the quality of translation by enabling selective source sentence lookup.\nThe decoder LSTM computes: DISPLAYFORM0 \nwhere the probability is computed as a function of the decoder's output in the previous time step INLINEFORM0 , the hidden layer vector of the decoder in the current timestep INLINEFORM1 and the context vector from the attention mechanism INLINEFORM2 . The context vector INLINEFORM3 for time step INLINEFORM4 is computed as a weighted sum of the output of the entire sentence using a weight parameter INLINEFORM5 : DISPLAYFORM0 \nwhere INLINEFORM0 is the number of tokens in the source sentence, INLINEFORM1 refers to the value of the hidden layer of the encoder at time step INLINEFORM2 , and INLINEFORM3 is the alignment parameter. This parameter is calculated by means of a feed forward neural network to ensure that the alignment model is free from the difficulties of contextualization of long sentences into a single vector. The feed forward network is trained along with the neural translation model to jointly improve the performance of the translation. Mathematically, DISPLAYFORM0 DISPLAYFORM1 \nwhere INLINEFORM0 is the softmax output of the result of the feedforward network, INLINEFORM1 is the hidden state value of the decoder at timestep INLINEFORM2 and INLINEFORM3 is the encoder's hidden layer annotation at timestep INLINEFORM4 . A concatenation of the forward and the reverse hidden layer parameters of the encoder is used at each step to compute the weights INLINEFORM5 for the attention mechanism. This is done to enable an overall context of the sentence, as opposed to a context of only all the previous words of the sentence for every word in consideration. Fig. FIGREF12 is the general architecture of the neural translation model without the Bidirectional LSTM encoder.\nA global attention mechanism is preferred over local attention because the differences in the structures of the languages cannot be mapped efficiently to enable lookup into the right parts of the source sentence. Using local attention mechanism with a monotonic context lookup, where the region around INLINEFORM0 source word is looked up for the prediction of the INLINEFORM1 target word, is impractical because of the structural discordance between the English and Tamil sentences (see Figs. FIGREF37 and FIGREF44 ). The use of gaussian and other such distributions to facilitate local attention would also be inefficient because the existence of various forms of translations for the same source sentence involving morphological and structural variations that don't stay uniform through the entire corpus BIBREF5 .\nThe No Peepholes (NP) variant of the LSTM cell, formulated in Greff et al. greff2015lstm is used in this experiment as it proved to give the best results amongst all the variants of an LSTM cell. It is specified by means of a gated mechanism designed to ensure that the vanishing gradient problem is prevented. LSTM maintains its hidden layer in two components, the cell vector INLINEFORM0 and the actual hidden layer output vector INLINEFORM1 . The cell vector is ensured to never reach zero by means of a weighted sum of the previous layer's cell vector INLINEFORM2 regulated by the forget gate INLINEFORM3 and an activation of the weighted sum of the input INLINEFORM4 in the current timestep INLINEFORM5 and the previous timestep's hidden layer output vector INLINEFORM6 . The combination is similarly regulated by the input gate INLINEFORM7 . The hidden layer output is determined as an activation of the cell gate, regulated by the output gate INLINEFORM8 . The interplay between these two vectors ( INLINEFORM9 and INLINEFORM10 ) at every timestep ensures that the problem of vanishing gradients doesn't occur. The three gates are also formed as a sigmoid of the weighted sum of the previous hidden layer output INLINEFORM11 and the input in the current timestep INLINEFORM12 . The output generated out of the LSTM's hidden layer is specified as a weighted softmax over the hidden layer output INLINEFORM13 . The learnable parameters of an LSTM cell are all the weights INLINEFORM14 and the biases INLINEFORM15 . DISPLAYFORM0 \nThe LSTM specified by equations 7 through 11 is the one used for the decoder of the model. The encoder uses a bidirectional RNN LSTM cell in which there are two hidden layer components INLINEFORM0 and INLINEFORM1 that contribute to the output INLINEFORM2 of each time step INLINEFORM3 . Both the components have their own sets of LSTM equations in such a way that INLINEFORM4 for every timestep is computed from the first timestep till the INLINEFORM5 token is reached and INLINEFORM6 is computed from the INLINEFORM7 timestep backwards until the first token is reached. All the five vectors of the two components are all exactly the same as the LSTM equations specified with one variation in the computation of the result. DISPLAYFORM0 \nThe model used for translation is the one implemented by Bahdanau et al. (2014).",

We conducted a feature ablation study by holding out (sans) each feature group and training and testing the support vector model using a linear kernel and 5-fold, stratified cross-validation. We report the average F1-score from our baseline approach (all feature groups) and report the point difference (+ or -) in F1-score performance observed by ablating each feature set.\nBy ablating each feature group from the full dataset, we observed the following count of features - sans lexical: 185, sans syntactic: 16,935, sans emotion: 16,954, sans demographics: 16,946, sans sentiment: 16,950, sans personality: 16,946, and sans LIWC: 16,832. In Figure 1, compared to the baseline performance, significant drops in F1-scores resulted from sans lexical for depressed mood (-35 points), disturbed sleep (-43 points), and depressive symptoms (-45 points). Less extensive drops also occurred for evidence of depression (-14 points) and fatigue or loss of energy (-3 points). In contrast, a 3 point gain in F1-score was observed for no evidence of depression. We also observed notable drops in F1-scores for disturbed sleep by ablating demographics (-7 points), emotion (-5 points), and sentiment (-5 points) features. These F1-score drops were accompanied by drops in both recall and precision. We found equal or higher F1-scores by removing non-lexical feature groups for no evidence of depression (0-1 points), evidence of depression (0-1 points), and depressive symptoms (2 points).\nUnsurprisingly, lexical features (unigrams) were the largest contributor to feature counts in the dataset. We observed that lexical features are also critical for identifying depressive symptoms, specifically for depressed mood and for disturbed sleep. For the classes higher in the hierarchy - no evidence of depression, evidence of depression, and depressive symptoms - the classifier produced consistent F1-scores, even slightly above the baseline for depressive symptoms and minor fluctuations of change in recall and precision when removing other feature groups suggesting that the contribution of non-lexical features to classification performance was limited. However, notable changes in F1-score were observed for the classes lower in the hierarchy including disturbed sleep and fatigue or loss of energy. For instance, changes in F1-scores driven by both recall and precision were observed for disturbed sleep by ablating demographics, emotion, and sentiment features, suggesting that age or gender (“mid-semester exams have me restless”), polarity and subjective terms (“lack of sleep is killing me”), and emoticons (“wide awake :(”) could be important for both identifying and correctly classifying a subset of these tweets.\nFeature ablation studies are conducted to assess the informativeness of a feature group by quantifying the change in predictive power when comparing the performance of a classifier trained with the all feature groups versus the performance without a particular feature group.",

        "evidence": "The race and gender bias evaluation was carried out on the output of the 219 automatic systems that participated in SemEval-2018 Task 1: Affect in Tweets BIBREF5 . The shared task included five subtasks on inferring the affectual state of a person from their tweet: 1. emotion intensity regression, 2. emotion intensity ordinal classification, 3. valence (sentiment) regression, 4. valence ordinal classification, and 5. emotion classification. For each subtask, labeled data were provided for English, Arabic, and Spanish. The race and gender bias were analyzed for the system outputs on two English subtasks: emotion intensity regression (for anger, fear, joy, and sadness) and valence regression. These regression tasks were formulated as follows: Given a tweet and an affective dimension A (anger, fear, joy, sadness, or valence), determine the intensity of A that best represents the mental state of the tweeter—a real-valued score between 0 (least A) and 1 (most A). Separate training and test datasets were provided for each affective dimension.\nTraining sets included tweets along with gold intensity scores. Two test sets were provided for each task: 1. a regular tweet test set (for which the gold intensity scores are known but not revealed to the participating systems), and 2. the Equity Evaluation Corpus (for which no gold intensity labels exist). Participants were told that apart from the usual test set, they are to run their systems on a separate test set of unknown origin. The participants were instructed to train their system on the tweets training sets provided, and that they could use any other resources they may find or create. They were to run the same final system on the two test sets. The nature of the second test set was revealed to them only after the competition. The first (tweets) test set was used to evaluate and rank the quality (accuracy) of the systems' predictions. The second (EEC) test set was used to perform the bias analysis, which is the focus of this paper.\nSystems: Fifty teams submitted their system outputs to one or more of the five emotion intensity regression tasks (for anger, fear, joy, sadness, and valence), resulting in 219 submissions in total. Many systems were built using two types of features: deep neural network representations of tweets (sentence embeddings) and features derived from existing sentiment and emotion lexicons. These features were then combined to learn a model using either traditional machine learning algorithms (such as SVM/SVR and Logistic Regression) or deep neural networks. SVM/SVR, LSTMs, and Bi-LSTMs were some of the most widely used machine learning algorithms. The sentence embeddings were obtained by training a neural network on the provided training data, a distant supervision corpus (e.g., AIT2018 Distant Supervision Corpus that has tweets with emotion-related query terms), sentiment-labeled tweet corpora (e.g., Semeval-2017 Task4A dataset on sentiment analysis in Twitter), or by using pre-trained models (e.g., DeepMoji BIBREF20 , Skip thoughts BIBREF21 ). The lexicon features were often derived from the NRC emotion and sentiment lexicons BIBREF22 , BIBREF23 , BIBREF24 , AFINN BIBREF25 , and Bing Liu Lexicon BIBREF26 .\nWe provided a baseline SVM system trained using word unigrams as features on the training data (SVM-Unigrams). This system is also included in the current analysis.\nMeasuring bias: To examine gender bias, we compared each system's predicted scores on the EEC sentence pairs as follows:\n\nThus, eleven pairs of scores (ten pairs of scores from ten noun phrase pairs and one pair of scores from the averages on name subsets) were examined for each template–emotion word instantiation. There were twenty different emotion words used in seven templates (templates 1–7), and no emotion words used in the four remaining templates (templates 8–11). In total, INLINEFORM0 pairs of scores were compared.\nSimilarly, to examine race bias, we compared pairs of system predicted scores as follows:\n\nThus, one pair of scores was examined for each template–emotion word instantiation. In total, INLINEFORM0 pairs of scores were compared.\nFor each system, we calculated the paired two sample t-test to determine whether the mean difference between the two sets of scores (across the two races and across the two genders) is significant. We set the significance level to 0.05. However, since we performed 438 assessments (219 submissions evaluated for biases in both gender and race), we applied Bonferroni correction. The null hypothesis that the true mean difference between the paired samples was zero was rejected if the calculated p-value fell below INLINEFORM0 .\nWe provided a baseline SVM system trained using word unigrams as features on the training data (SVM-Unigrams).

        "question": "Extract examples of electrical conduction from the following passage.",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

Our model achieves significant performance gains in the test sets over the baseline for both Italian and Finnish query translation. The overall low MAP for NMT can possibly be improved with larger TC. Moreover, our model validation approach requires access to RC index, and it slows down overall training process. Hence, we could not train our model for a large number of epochs - it may be another cause of the low performance.\nWe want to show that translation terms generated by our multi-task transformer are roughly equally likely to be seen in the Europarl corpus (TC) or the CLEF corpus (RC). Given a translation term INLINEFORM0 , we compute the ratio of the probability of seeing INLINEFORM1 in TC and RC, INLINEFORM2 . Here, INLINEFORM3 and INLINEFORM4 is calculated similarly. Given a query INLINEFORM5 and its translation INLINEFORM6 provided by model INLINEFORM7 , we calculate the balance of INLINEFORM8 , INLINEFORM9 . If INLINEFORM10 is close to 1, the translation terms are as likely in TC as in RC. Figure FIGREF15 shows the balance values for transformer and our model for a random sample of 20 queries from the validation set of Italian queries, respectively. Figure FIGREF16 shows the balance values for transformer and our model for a random sample of 20 queries from the test set of Italian queries, respectively. It is evident that our model achieves better balance compared to baseline transformer, except for a very few cases.\nGiven a query INLINEFORM0 , consider INLINEFORM1 as the set of terms from human translation of INLINEFORM2 and INLINEFORM3 as the set of translation terms generated by model INLINEFORM4 . We define INLINEFORM5 and INLINEFORM6 as precision and recall of INLINEFORM7 for model INLINEFORM8 . In Table TABREF19 , we report average precision and recall for both transformer and our model across our train and validation query set over two language pairs. Our model generates precise translation, i.e. it avoids terms that might be useless or even harmful for retrieval. Generally, from our observation, avoided terms are highly likely terms from TC and they are generated because of translation model overfitting. Our model achieves a regularization effect through an auxiliary task. This confirms results from existing multi-tasking literature BIBREF15 .\nTo explore translation quality, consider pair of sample translations provided by two models. For example, against an Italian query, medaglia oro super vinse medaglia oro super olimpiadi invernali lillehammer, translated term set from our model is {gold, coin, super, free, harmonising, won, winter, olympics}, while transformer output is {olympic, gold, one, coin, super, years, won, parliament, also, two, winter}. Term set from human translation is: {super, gold, medal, won, lillehammer, olypmic, winter, games}. Transformer comes up with terms like parliament, also, two and years that never appears in human translation. We found that these terms are very likely in Europarl and rare in CLEF. Our model also generates terms such as harmonising, free, olympics that not generated by transformer. However, we found that these terms are equally likely in Europarl and CLEF.\nOur model achieves significant performance gains in the test sets over the baseline for both Italian and Finnish query translation.",

        "answer": "It is based on matching queries and documents by the semantic measure.",
        "evidence": "In information retrieval (IR), queries and documents are typically represented by term vectors where each term is a content word and weighted by tf-idf, i.e. the product of the term frequency and the inverse document frequency, or other weighting schemes BIBREF0 . The similarity of a query and a document is then determined as a dot product or cosine similarity. Although this works reasonably, the traditional IR scheme often fails to find relevant documents when synonymous or polysemous words are used in a dataset, e.g. a document including only “neoplasm\" cannot be found when the word “cancer\" is used in a query. One solution of this problem is to use query expansion BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 or dictionaries, but these alternatives still depend on the same philosophy, i.e. queries and documents should share exactly the same words.\nWhile the term vector model computes similarities in a sparse and high-dimensional space, the semantic analysis methods such as latent semantic analysis (LSA) BIBREF5 , BIBREF6 and latent Dirichlet allocation (LDA) BIBREF7 learn dense vector representations in a low-dimensional space. These methods choose a vector embedding for each term and estimate a similarity between terms by taking an inner product of their corresponding embeddings BIBREF8 . Since the similarity is calculated in a latent (semantic) space based on context, the semantic analysis approaches do not require having common words between a query and documents. However, it has been shown that LSA and LDA methods do not produce superior results in various IR tasks BIBREF9 , BIBREF10 , BIBREF11 and the classic ranking method, BM25 BIBREF12 , usually outperforms those methods in document ranking BIBREF13 , BIBREF14 .\nNeural word embedding BIBREF15 , BIBREF16 is similar to the semantic analysis methods described above. It learns low-dimensional word vectors from text, but while LSA and LDA utilize co-occurrences of words, neural word embedding learns word vectors to predict context words BIBREF10 . Moreover, training of semantic vectors is derived from neural networks. Both co-occurrence and neural word embedding approaches have been used for lexical semantic tasks such as semantic relatedness (e.g. king and queen), synonym detection (e.g. cancer and carcinoma) and concept categorization (e.g. banana and pineapple belong to fruits) BIBREF10 , BIBREF17 . But, Baroni et al. Baroni2014 showed that neural word embedding approaches generally performed better on such tasks with less effort required for parameter optimization. The neural word embedding models have also gained popularity in recent years due to their high performance in NLP tasks BIBREF18 .\nHere we present a query-document similarity measure using a neural word embedding approach. This work is particularly motivated by the Word Mover's Distance BIBREF19 . Unlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document. Our first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets BIBREF20 , BIBREF21 , and the experimental results showed that our approach was better than BM25 ranking. This was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.\nIn general, conventional ranking models (e.g. BM25) rely on a manually designed ranking function and require heuristic optimization for parameters BIBREF22 , BIBREF23 . In the age of information explosion, this one-size-fits-all solution is no longer adequate. For instance, it is well known that links to a web page are an important source of information in web document search BIBREF24 , hence using the link information as well as the relevance between a query and a document is crucial for better ranking. In this regard, learning to rank BIBREF22 has drawn much attention as a scheme to learn how to combine diverse features. Given feature vectors of documents and their relevance levels, a learning to rank approach learns an optimal way of weighting and combining multiple features.\nWe argue that the single scores (or features) produced by BM25 and our proposed semantic measure complement each other, thus merging these two has a synergistic effect. To confirm this, we measured the impact on document ranking by combining BM25 and semantic scores using the learning to rank approach, LamdaMART BIBREF25 , BIBREF26 . Trained on PubMed user queries and their click-through data, we evaluated the search performance based on the most highly ranked 20 documents. As a result, we found that using our semantic measure further improved the performance of BM25.\nTaken together, we make the following important contributions in this work. First, to the best of our knowledge, this work represents the first investigation of query-document similarity for information retrieval using the recently proposed Word Mover's Distance. Second, we modify the original Word Mover's Distance algorithm so that it is computationally less expensive and thus more practical and scalable for real-world search scenarios (e.g. biomedical literature search). Third, we measure the actual impact of neural word embeddings in PubMed by utilizing user queries and relevance information derived from click-through data. Finally, on TREC and PubMed datasets, our proposed method achieves stronger performance than BM25.\nThis was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.",

        "question": "You state in section 3.1 that you do not consider Cysteine for experimental reasons? Why? Can you elaborate on the implied limitations of this choice?",
        "answer": "Thank you, we agree this should have been explained in more detail and we have added further explanation to the text in 3.1 that additionally links to further detail in Appendix A.6. In short, not including cysteine is common in de novo protein design studies and does not pose any significant limitations to our work or the conclusions drawn from it. It also provides a benefit. Its inclusion makes expression of any designed sequence in bacteria (the most common way to produce designs in the lab) more challenging.\nCysteine is special among amino acids, as it is mainly occurs in proteins to form disulfide bonds, particularly secreted proteins and outwards facing membrane proteins. This happens between pairs of cysteines, and forms a strong, usually stabilizing, bond between them. This bond cannot form in the cytosol of the cell, so disulfide containing proteins are expressed in an otherwise different way. This is the root cause of why it complicates validation of designed sequences. In de novo design literature the inclusion of cysteine is typically discussed as the inclusion of disulfide bonds. De novo designed proteins are known for being hyperstable without disulfides, and it is often a question of if the inclusion of disulfide bonds is justified. In other words, its common that the default stance is to not include disulfide bonds or to add them to preexisting candidates. For example, the Rosetta software package has separate protocols explicitly for adding disulfides to designs. Similarly to trDesign, we don't feel that including them here provides a clear benefit compared to the complications it brings.",

        "evidence": "\nThe goal of meeting transcription is to have machines generate speaker-annotated transcripts of natural meetings based on their audio and optionally video recordings. Meeting transcription and analytics would be a key to enhancing productivity as well as improving accessibility in the workplace. It can also be used for conversation transcription in other domains such as healthcare BIBREF0. Research in this space was promoted in the 2000s by NIST Rich Transcription Evaluation series and public release of relevant corpora BIBREF1, BIBREF2, BIBREF3. While systems developed in the early days yielded high error rates, advances have been made in individual component technology fields, including conversational speech recognition BIBREF4, BIBREF5, far-field speech processing BIBREF6, BIBREF7, BIBREF8, and speaker identification and diarization BIBREF9, BIBREF10, BIBREF11. When cameras are used in addition to microphones to capture the meeting conversations, speaker identification quality could be further improved thanks to the computer vision technology. These trends motivated us to build an end-to-end audio-visual meeting transcription system to identify and address unsolved challenges. This report describes our learning, with focuses on overall architecture design, overlapped speech recognition, and audio-visual speaker diarization.\nWhen designing meeting transcription systems, different constraints must be taken into account depending on targeted scenarios. In some cases, microphone arrays are used as an input device. If the names of expected meeting attendees are known beforehand, the transcription system should be able to provide each utterance with the true identity (e.g., “Alice” or “Bob”) instead of a randomly generated label like “Speaker1”. It is often required to show the transcription in near real time, which makes the task more challenging.\nThis work assumes the following scenario. We consider a scheduled meeting setting, where an organizer arranges a meeting in advance and sends invitations to attendees. The transcription system has access to the invitees' names. However, actual attendees may not completely match those invited to the meeting. The users are supposed to enroll themselves in the system beforehand so that their utterances in the meeting can be associated with their names. The meeting is recorded with an audio-visual device equipped with a seven-element circular microphone array and a fisheye camera. Transcriptions must be shown with a latency of up to a few seconds.\nThis paper investigates three key challenges.\n\nSpeech overlaps: Recognizing overlapped speech has been one of the main challenges in meeting transcription with limited tangible progress. Numerous multi-channel speech separation methods were proposed based on independent component analysis or spatial clustering BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. However, there was little successful effort to apply these methods to natural meetings. Neural network-based single-channel separation methods using techniques like permutation invariant training (PIT) BIBREF18 or deep clustering (DC) BIBREF19 are known to be vulnerable to various types of acoustic distortion, including reverberation and background noise BIBREF20. In addition, these methods were tested almost exclusively on small-scale segmented synthetic data and have not been applied to continuous conversational speech audio. Although the recently held CHiME-5 challenge helped the community make a step forward to a realistic setting, it still allowed the use of ground-truth speaker segments BIBREF21, BIBREF22.\nWe address this long-standing problem with a continuous speech separation (CSS) approach, which we proposed in our latest conference papers BIBREF23, BIBREF24. It is based on an observation that the maximum number of simultaneously active speakers is usually limited even in a large meeting. According to BIBREF25, two or fewer speakers are active for more than 98% of the meeting time. Thus, given continuous multi-channel audio observation, we generate a fixed number, say $N$, of time-synchronous signals. Each utterance is separated from overlapping voices and background noise. Then, the separated utterance is spawned from one of the $N$ output channels. For periods where the number of active speakers is fewer than $N$, the extra channels generate zeros. We show how continuous speech separation can fit in with an overall meeting transcription architecture to generate speaker-annotated transcripts.\nNote that our speech separation system does not make use of a camera signal. While much progress has been made in audio-visual speech separation, the challenge of dealing with all kinds of image variations remains unsolved BIBREF26, BIBREF27, BIBREF28.\n\nExtensible framework: It is desirable that a single transcription system be able to support various application settings for both maintenance and scalability purposes. While this report focuses on the audio-visual setting, our broader work covers an audio-only setting as well as the scenario where no prior knowledge of meeting attendees is available. A modular and versatile architecture is desired to encompass these different settings.\nTo this end, we propose a framework called SRD, which stands for “separate, recognize, and diarize”, where CSS, speech recognition, and speaker diarization takes place in tandem. Performing CSS at the beginning allows the other modules to operate on overlap-free signals. Diarization is carried out after speech recognition because its implementation can vary significantly depending on the application settings. By choosing an appropriate diarization module for each setting, multiple use cases can be supported without changing the rest of the system. This architecture also allows transcriptions to be displayed in real time without speaker information. Speaker identities for each utterance may be shown after a couple of seconds.\n\nAudio-visual speaker diarization: Speaker diarization, a process of segmenting input audio and assigning speaker labels to the individual segments, can benefit from a camera signal. The phenomenal improvements that have been made to face detection and identification algorithms by convolutional neural networks (CNNs) BIBREF29, BIBREF30, BIBREF31 make the camera signal very appealing for speaker diarization. While much prior work assumes the batch processing scenario where the entire meeting recording can be processed multiple times, several studies deal with online processing BIBREF32, BIBREF33, BIBREF34, BIBREF35. However, no previous studies comprehensively address the challenges that one might encounter in real meetings. BIBREF32, BIBREF33 do not cope with speech overlaps. While the methods proposed in BIBREF34, BIBREF35 address the overlap issue, they rely solely on spatial cues and thus are not applicable when multiple speakers sit side by side.\nOur diarization method handles overlapping utterances as well as co-located speakers by utilizing the time-frequency (TF) masks generated by CSS in speaker identification and sound source localization (SSL). In addition, several enhancements are made to face identification to improve robustness to image variations caused by face occlusions, extreme head pose, lighting conditions, and so on.\nThese trends motivated us to build an end-to-end audio-visual meeting transcription system to identify and address unsolved challenges.",

        "evidence": "Neural machine translation (NMT) BIBREF0 is a promising paradigm for extracting translation knowledge from parallel text. NMT systems have achieved competitive accuracy rates under large-data training conditions for language pairs such as English-French. However, neural methods are data-hungry and learn poorly from low-count events. This behavior makes vanilla NMT a poor choice for low-resource languages, where parallel data is scarce. Table 1 shows that for 4 low-resource languages, a standard string-to-tree statistical MT system (SBMT) BIBREF1 , BIBREF2 strongly outperforms NMT, even when NMT uses the state-of-the-art local attention plus feed-input techniques from luong2015effective.\nIn this paper, we give a method for substantially improving NMT results on these languages. Neural models learn representations of their input that are often useful across tasks. Our key idea is to first train a high-resource language pair, then use the resulting trained network (the parent model) to initialize and constrain training for our low-resource language pair (the child model). We find that we can optimize our results by fixing certain parameters of the parent model, letting the rest be fine-tuned by the child model. We report NMT improvements from transfer learning of 5.6 Bleu on average, and we provide an analysis of why the method works. The final NMT system approaches strong SBMT baselines in in all four language pairs, and exceeds SBMT performance in one of them. Furthermore, we show that NMT is an exceptional re-scorer of `traditional' MT output; even NMT that on its own is worse than SBMT is consistently able to improve upon SBMT system output when incorporated as a re-scoring model.\nWe start by a brief description of our NMT model in Section \"NMT Background\" .

We show the effects of freezing, fine-tuning, and smarter initialization of different components of the attention-based NMT system during transfer. We compare the learning curves of transfer and no-transfer models showing that transfer solves an overfitting problem, not a search problem.

        "question": "What is the history of the travelling salesman problem throughout the years in a short bulleted list?",
        "evidence": "The origins of the travelling salesman problem are unclear. A handbook for travelling salesmen from 1832 mentions the problem and includes example tours through Germany and Switzerland, but contains no mathematical treatment.\n\n\nWilliam Rowan Hamilton\nThe TSP was mathematically formulated in the 19th century by the Irish mathematician William Rowan Hamilton and by the British mathematician Thomas Kirkman. Hamilton's icosian game was a recreational puzzle based on finding a Hamiltonian cycle. The general form of the TSP appears to have been first studied by mathematicians during the 1930s in Vienna and at Harvard, notably by Karl Menger, who defines the problem, considers the obvious brute-force algorithm, and observes the non-optimality of the nearest neighbour heuristic:\n\nWe denote by messenger problem (since in practice this question should be solved by each postman, anyway also by many travelers) the task to find, for finitely many points whose pairwise distances are known, the shortest route connecting the points. Of course, this problem is solvable by finitely many trials. Rules which would push the number of trials below the number of permutations of the given points, are not known. The rule that one first should go from the starting point to the closest point, then to the point closest to this, etc., in general does not yield the shortest route.\n\nIt was first considered mathematically in the 1930s by Merrill M. Flood who was looking to solve a school bus routing problem. Hassler Whitney at Princeton University generated interest in the problem, which he called the \"48 states problem\". The earliest publication using the phrase \"travelling salesman problem\" was the 1949 RAND Corporation report by Julia Robinson, \"On the Hamiltonian game (a traveling salesman problem).\"\n\nIn the 1950s and 1960s, the problem became increasingly popular in scientific circles in Europe and the United States after the RAND Corporation in Santa Monica offered prizes for steps in solving the problem. Notable contributions were made by George Dantzig, Delbert Ray Fulkerson and Selmer M. Johnson from the RAND Corporation, who expressed the problem as an integer linear program and developed the cutting plane method for its solution. They wrote what is considered the seminal paper on the subject in which with these new methods they solved an instance with 49 cities to optimality by constructing a tour and proving that no other tour could be shorter. Dantzig, Fulkerson and Johnson, however, speculated that given a near optimal solution we may be able to find optimality or prove optimality by adding a small number of extra inequalities (cuts). They used this idea to solve their initial 49 city problem using a string model. They found they only needed 26 cuts to come to a solution for their 49 city problem. While this paper did not give an algorithmic approach to TSP problems, the ideas that lay within it were indispensable to later creating exact solution methods for the TSP, though it would take 15 years to find an algorithmic approach in creating these cuts. As well as cutting plane methods, Dantzig, Fulkerson and Johnson used branch and bound algorithms perhaps for the first time.\n\nIn 1959, Jillian Beardwood, J.H. Halton and John Hammersley published an article entitled \"The Shortest Path Through Many Points\" in the journal of the Cambridge Philosophical Society. The Beardwood–Halton–Hammersley theorem provides a practical solution to the travelling salesman problem. The authors derived an asymptotic formula to determine the length of the shortest route for a salesman who starts at a home or office and visits a fixed number of locations before returning to the start.\n\nIn the following decades, the problem was studied by many researchers from mathematics, computer science, chemistry, physics, and other sciences. In the 1960s, however, a new approach was created, that instead of seeking optimal solutions would produce a solution whose length is provably bounded by a multiple of the optimal length, and in doing so would create lower bounds for the problem; these lower bounds would then be used with branch and bound approaches. One method of doing this was to create a minimum spanning tree of the graph and then double all its edges, which produces the bound that the length of an optimal tour is at most twice the weight of a minimum spanning tree.\n\nIn 1976, Christofides and Serdyukov independently of each other made a big advance in this direction: the Christofides-Serdyukov algorithm yields a solution that, in the worst case, is at most 1.5 times longer than the optimal solution. As the algorithm was simple and quick, many hoped it would give way to a near optimal solution method. However, this hope for improvement did not immediately materialize, and Christofides-Serdyukov remained the method with the best worst-case scenario until 2011, when a (very) slightly improved approximation algorithm was developed for the subset of \"graphical\" TSPs. In 2020 this tiny improvement was extended to the full (metric) TSP.\n\nRichard M. Karp showed in 1972 that the Hamiltonian cycle problem was NP-complete, which implies the NP-hardness of TSP. This supplied a mathematical explanation for the apparent computational difficulty of finding optimal tours.\n\nGreat progress was made in the late 1970s and 1980, when Grötschel, Padberg, Rinaldi and others managed to exactly solve instances with up to 2,392 cities, using cutting planes and branch and bound.\n\nIn the 1990s, Applegate, Bixby, Chvátal, and Cook developed the program Concorde that has been used in many recent record solutions. Gerhard Reinelt published the TSPLIB in 1991, a collection of benchmark instances of varying difficulty, which has been used by many research groups for comparing results. In 2006, Cook and others computed an optimal tour through an 85,900-city instance given by a microchip layout problem, currently the largest solved TSPLIB instance. For many other instances with millions of cities, solutions can be found that are guaranteed to be within 2–3% of an optimal tour.",

With victory over Britain in the American Revolutionary War the former colonies were confirmed as the new United States of America. Just prior to declaring independence, the Thirteen Colonies in their traditional groupings were: New England (New Hampshire; Massachusetts; Rhode Island; Connecticut); Middle (New York; New Jersey; Pennsylvania; Delaware); Southern (Maryland; Virginia; North Carolina; South Carolina; and Georgia). The Thirteen Colonies came to have very similar political, constitutional, and legal systems, dominated by Protestant English-speakers. The first of these colonies was Virginia Colony in 1607, a Southern colony. While all these colonies needed to become economically viable, the founding of the New England colonies, as well as the colonies of Maryland and Pennsylvania, were substantially motivated by their founders' concerns related to the practice of religion. The other colonies were founded for business and economic expansion. The Middle Colonies were established on an earlier Dutch colony, New Netherland.

        "evidence": "Negotiations, either between individuals or entities, are ubiquitous in everyday human interactions ranging from sales to legal proceedings. Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nWe define a metric called Accuracy ± k, measuring the %age of cases where the model performs ‘well’, as controlled by k.

        "evidence": "Using GANs, we can train generative models in a two-player game setting between a discriminator and a generator, where the discriminator (a binary classifier) learns to distinguish between real and fake data samples and the generator tries to fool the discriminator by generating authentic and high quality output BIBREF16. GANs have shown to be successful in image generation tasks BIBREF17 and recently, some progress has been observed in text generation BIBREF13, BIBREF12, BIBREF15. Our generator is a language model trained using backpropagation through time BIBREF18. During the pre-training phase we optimize for MLE and during the GAN training phase, we optimize on the creativity reward from the discriminator. The discriminator's encoder has the same architecture as the generator encoder module with the addition of a pooled decoder layer. The decoder contains 3 $[Dense Batch Normalization,ReLU]$ blocks and an addtional $Sigmoid$ layer. The discriminator decoder takes the hidden state at the last time step of a sequence concatenated with both the max-pooled and mean-pooled representation of the hidden states BIBREF19 and outputs a number in the range $[0,1]$. The difficulty of using GANs in text generation comes from the discrete nature of text, making the model non-differentiable hence, we update parameters for the generator model with policy gradients as described in Yu BIBREF15.\nWe utilize AWD-LSTM BIBREF20 and TransformerXL BIBREF21 based language models. For model hyperparameters please to refer to Supplementary Section Table TABREF5. We use Adam optimizer BIBREF22 with $\\beta 1= 0.7$ and $\\beta 2= 0.8$ similar to BIBREF19 and use a batch size of 50. Other practices for LM training were the same as BIBREF21 and BIBREF20 for Transformer-XL and AWD-LSTM respectively. We refer to our proposed GAN as Creative-GAN and compare it to a baseline (a language model equivalent to our pre-trained generator) and a GumbelGAN model BIBREF14 across all proposed datasets. We use three creative English datasets with distinct linguistic characteristics: (1) A corpus of 740 classical and contemporary English poems, (2) a corpus of 14950 metaphor sentences retrieved from a metaphor database website and (3) a corpus of 1500 song lyrics ranging across genres. The mix of linguistic styles within this corpus offers the potential for interesting variation during the generation phase. We use the same pre-processing as in earlier work BIBREF19, BIBREF23. We reserve 10% of our data for test set and another 10% for our validation set.\nWe first pre-train our generator on the Gutenberg dataset BIBREF24 for 20 epochs and then fine-tune BIBREF19 them to our target datasets with a language modeling objective. The discriminator's encoder is initialized to the same weights as our fine-tuned language model. Once we have our fine-tuned encoders for each target dataset, we train in an adversarial manner. The discriminator objective here is to score the quality of the creative text. The discriminator is trained for 3 iterations for every iteration of the generator, a practice seen in previous work BIBREF25. Creative-GAN relies on using the reward from the discriminator BIBREF12, BIBREF15 for backpropagation. We follow a similar training procedure for GumbelGAN. Outputs are generated through sampling over a multinomial distribution for all methods, instead of $argmax$ on the log-likelihood probabilities, as sampling has shown to produce better output quality BIBREF4. Please refer to Supplementary Section Table TABREF6 for training parameters of each dataset and Table TABREF5 for hyperparameters of each encoder. We pick these values after experimentation with our validation set. Training and output generation code can be found online.\nDuring the pre-training phase we optimize for MLE and during the GAN training phase, we optimize on the creativity reward from the discriminator.

        "answer": "Yes, it is.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages.",

We have also refined Algorithm 1 to handle client sampling on every training round. Specifically, when clients are newly sampled, we update their online and target encoders with the global model; when clients are sampled in the previous round, we update only the online encoders with EMA. In definition, cross-device FL assumes there are millions of stateless clients that might participate in training just once. While due to the constraints of experimental settings, the majority of studies conduct experiments with at most hundreds of clients. FedEMA can work under such experimental settings by caching states of clients in the server. When the number of clients scales to millions, FedEMA degrades to FedBYOL that updates both encoders --- without keeping any local states.

        "evidence": "4 methods, i.e., GCQL (Ours), CQL, REDQ and AWAC, are tested on 3 tasks, i.e., Walker, Hopper and HalfCheetah, and each task has 5 different kinds of offline dataset, which are random-v0, medium-v0, expert-v0, medium-expert-v0, and medium-replay-v0. As online interactions are available, we take the maximization over testing scores during the whole training process, and report the average of these max scores across five different seeds in Table. Please note that the results of AWAC are directly taken from their paper. As shown in Table, our method gains a better performance than the baselines in all tasks. Particularly, for the medium-replay and random dataset, our GCQL outperforms the baselines by a large margin. By contrast, CQL also achieves an expert performance on the high-quality dataset, e.g., expert and medium-expert tasks. For these high-quality datasets, our method achieves a comparable or slightly better performance over CQL. In terms of the online RL method REDQ, it fails on almost all tasks. Even though we employ an online limited exploration process, conventional online RL cannot benefit from such limited experiences. On the contrary, such limited online experiences could bring catastrophic consequences, e.g., on the halfcheetah-medium-replay task, REDQ suffers a significant instability issue. On the other hand, when dataset quality is high, e.g., expert or medium-expert dataset, our method can leverage the benefit of the offline RL that gains an expert performance with very limited interaction steps, such as around 20K steps. By contrast, when dataset quality is poor, e.g., the random or medium-replay dataset, only our method can learn effectively with less than 100K online steps, which demonstrate that our method can take the advantage of the limited online experiences as much as possible. In sum, our method can benefit the most from the limited online experience while still maintain the offline learning's ability. Besides, We also include the corresponding learning curves in Appendix A for a comprehensive understanding. These learning curves demonstrate that our method also achieves a better final average score at the last iteration in most cases.\nAs online interactions are available, we take the maximization over testing scores during the whole training process, and report the average of these max scores across five different seeds in Table 1.",

        "answer": "The authors train models on a symbol replacement task with a well defined generalizable structure.",
        "evidence": "It is well known that language has certain structural properties which allows natural language speakers to make “infinite use of finite means\" BIBREF3 . This structure allows us to generalize beyond the typical machine learning definition of generalization BIBREF4 (which considers performance on the distribution that generated the training set), permitting the understanding of any utterance sharing the same structure, regardless of probability. For example, sentences of length 100 typically do not appear in natural text or speech (our personal 'training set'), but can be understood regardless due to their structure. We refer to this notion as linguistic generalization .\nMany problems in NLP are treated as sequence to sequence tasks with solutions built on seq2seq-attention based models. While these models perform very well on standard datasets and also appear to capture some linguistic structure BIBREF5 , BIBREF6 , BIBREF7 , they also can be quite brittle, typically breaking on uncharacteristic inputs BIBREF8 , BIBREF1 , indicating that the extent of linguistic generalization these models achieve is still somewhat lacking.\nDue to the high capacity of these models, it is not unreasonable to expect them to learn some structure from the data. However, learning structure is not a sufficient condition to achieving linguistic generalization. If this structure is to be usable on data outside the training distribution, the model must learn the structure without additionally learning (overfitting on) patterns specific to the training data. One may hope, given the right hyperparameter configuration and regularization, that a model converges to a solution that captures the reusable structure without overfitting too much on the training set. While this solution exists in theory, in practice, it may be difficult to find.\nIn this work, we look at the feasibility of training and tuning seq2seq-attention models towards a solution that generalizes in this linguistic sense. In particular, we train models on a symbol replacement task with a well defined generalizable structure. The task is simple enough that all models achieve near perfect accuracy on the standard test set, i.e., where the inputs are drawn from the same distribution as that of the training set. We then test these models for linguistic generalization by creating test sets of uncharacteristic inputs, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned. Our results indicate that generalization is highly sensitive; such that even changes in the random seed can drastically affect the ability to generalize. This dependence on an element that is not (or ideally should not be) a hyperparameter suggests that the line between generalization and failure is quite fine, and may not be feasible to reach simply by hyperparameter tuning alone.\nIn particular, we train models on a symbol replacement task with a well defined generalizable structure.",

In March 1948, this alliance was expanded in the Treaty of Brussels to include the Benelux countries, forming the Brussels Treaty Organization, commonly known as the Western Union. Talks for a wider military alliance, which could include North America, also began that month in the United States, where their foreign policy under the Truman Doctrine promoted international solidarity against actions they saw as communist aggression, such as the February 1948 coup d'état in Czechoslovakia. These talks resulted in the signature of the North Atlantic Treaty on 4 April 1949 by the member states of the Western Union plus the United States, Canada, Portugal, Italy, Norway, Denmark, and Iceland. Canadian diplomat Lester B. Pearson was a key author and drafter of the treaty.\n\nA long rectangular room with multiple rows of seated individuals on each side, and flags hanging at the far end.\nWest Germany joined NATO in 1955, which led to the formation of the rival Warsaw Pact during the Cold War.\nThe North Atlantic Treaty was largely dormant until the Korean War initiated the establishment of NATO to implement it with an integrated military structure. This included the formation of Supreme Headquarters Allied Powers Europe (SHAPE) in 1951, which adopted many of the Western Union's military structures and plans, including their agreements on standardizing equipment and agreements on stationing foreign military forces in European countries. In 1952, the post of Secretary General of NATO was established as the organization's chief civilian. That year also saw the first major NATO maritime exercises, Exercise Mainbrace and the accession of Greece and Turkey to the organization. Following the London and Paris Conferences, West Germany was permitted to rearm militarily, as they joined NATO in May 1955, which was, in turn, a major factor in the creation of the Soviet-dominated Warsaw Pact, delineating the two opposing sides of the Cold War.\n\nThe building of the Berlin Wall in 1961 marked a height in Cold War tensions, when 400,000 US troops were stationed in Europe. Doubts over the strength of the relationship between the European states and the United States ebbed and flowed, along with doubts over the credibility of the NATO defence against a prospective Soviet invasion – doubts that led to the development of the independent French nuclear deterrent and the withdrawal of France from NATO's military structure in 1966. In 1982, the newly democratic Spain joined the alliance.\n\nThe Revolutions of 1989 in Europe led to a strategic re-evaluation of NATO's purpose, nature, tasks, and focus on the continent. In October 1990, East Germany became part of the Federal Republic of Germany and the alliance, and in November 1990, the alliance signed the Treaty on Conventional Armed Forces in Europe (CFE) in Paris with the Soviet Union. It mandated specific military reductions across the continent, which continued after the collapse of the Warsaw Pact in February 1991 and the dissolution of the Soviet Union that December, which removed the de facto main adversaries of NATO. This began a draw-down of military spending and equipment in Europe. The CFE treaty allowed signatories to remove 52,000 pieces of conventional armaments in the following sixteen years, and allowed military spending by NATO's European members to decline by 28 percent from 1990 to 2015. In 1990 assurances were given by several Western leaders to Mikhail Gorbachev that NATO would not expand further east, as revealed by memoranda of private conversations. However, the final text of the Treaty on the Final Settlement with Respect to Germany, signed later that year, contained no mention of the issue of eastward expansion.\n\nTwo tall concrete sections of a wall in a grass lawn in front of a curved building with blue-glass windows.\nThe Fall of the Berlin Wall in 1989 marked a turning point in NATO's role in Europe, and this section of the wall is now displayed outside NATO headquarters.\nIn the 1990s, the organization extended its activities into political and humanitarian situations that had not formerly been NATO concerns. During the Breakup of Yugoslavia, the organization conducted its first military interventions in Bosnia from 1992 to 1995 and later Yugoslavia in 1999. These conflicts motivated a major post-Cold War military restructuring. NATO's military structure was cut back and reorganized, with new forces such as the Headquarters Allied Command Europe Rapid Reaction Corps established.\n\nPolitically, the organization sought better relations with the newly autonomous Central and Eastern European states, and diplomatic forums for regional cooperation between NATO and its neighbours were set up during this post-Cold War period, including the Partnership for Peace and the Mediterranean Dialogue initiative in 1994, the Euro-Atlantic Partnership Council in 1997, and the NATO–Russia Permanent Joint Council in 1998. At the 1999 Washington summit, Hungary, Poland, and the Czech Republic officially joined NATO, and the organization also issued new guidelines for membership with individualized \"Membership Action Plans\". These plans governed the subsequent addition of new alliance members. The election of French President Nicolas Sarkozy in 2007 led to a major reform of France's military position, culminating with the return to full membership on 4 April 2009, which also included France rejoining the NATO Military Command Structure, while maintaining an independent nuclear deterrent.\n\nArticle 5 of the North Atlantic treaty, requiring member states to come to the aid of any member state subject to an armed attack, was invoked for the first and only time after the September 11 attacks, after which troops were deployed to Afghanistan under the NATO-led ISAF. The organization has operated a range of additional roles since then, including sending trainers to Iraq, assisting in counter-piracy operations, and in 2011 enforcing a no-fly zone over Libya in accordance with UN Security Council Resolution 1973.\n\nRussia's annexation of Crimea led to strong condemnation by all NATO members, and was one of the seven times that Article 4, which calls for consultation among NATO members, has been invoked. Prior times included during the Iraq War and Syrian Civil War. At the 2014 Wales summit, the leaders of NATO's member states formally committed for the first time to spend the equivalent of at least two percent of their gross domestic products on defence by 2024, which had previously been only an informal guideline. At the 2016 Warsaw summit, NATO countries agreed on the creation of NATO Enhanced Forward Presence, which deployed four multinational battalion-sized battlegroups in Estonia, Latvia, Lithuania, and Poland. Before and during the 2022 Russian invasion of Ukraine, several NATO countries sent ground troops, warships and fighter aircraft to reinforce the alliance's eastern flank, and multiple countries again invoked Article 4. In March 2022, NATO leaders met at Brussels for an extraordinary summit which also involved Group of Seven and European Union leaders. NATO member states agreed to establish four additional battlegroups in Bulgaria, Hungary, Romania, and Slovakia, and elements of the NATO Response Force were activated for the first time in NATO's history.\n\nAs of June 2022, NATO had deployed 40,000 troops along its 2,500-kilometre-long (1,550 mi) Eastern flank to deter Russian aggression. More than half of this number have been deployed in Bulgaria, Romania, Hungary, Slovakia, and Poland, which five countries muster a considerable combined ex-NATO force of 259,000 troops. To supplement Bulgaria's Air Force, Spain sent Eurofighter Typhoons, the Netherlands sent eight F-35 attack aircraft, and additional French and US attack aircraft would arrive soon as well.\n\nNATO enjoys public support across its member states.",

Its members in 1949 were the United States, Belgium, the Netherlands, Luxembourg, France, the United Kingdom, Canada, Portugal, Italy, Norway, Denmark and Iceland. On 18 February 1952, Greece and Turkey also joined.\n\nWhen West Germany joined the organization on 9 May 1955 it was described as \"a decisive turning point in the history of our continent\" by Halvard Lange, Foreign Minister of Norway at the time., the result was the Warsaw Pact, signed on 14 May 1955 by the Soviet Union and its satellite states as response to NATO.\n\nAfter the Cold War in 1999 three former communist countries, Hungary, the Czech Republic, and Poland joined NATO. On 29 March 2004 seven more Northern European and Eastern European countries joined NATO: Estonia, Latvia and Lithuania and also Slovenia, Slovakia, Bulgaria, and Romania.\n\nCroatia and Albania received NATO membership invitation on 3 April 2008. The Republic of Macedonia received the only conditional invitation because it was vetoed by Greece because of its name dispute with Greece.\n\nMontenegro joined on 5 June 2017.  Having changed its name to end the dispute, North Macedonia joined NATO on 27 March 2020 and became its 30th member.

        "question": "Based on the following paragraph on water, what makes water cohesive.",
        "evidence": "Life arose from the Earth's first ocean, which formed some 3.8 billion years ago. Since then, water continues to be the most abundant molecule in every organism. Water is important to life because it is an effective solvent, capable of dissolving solutes such as sodium and chloride ions or other small molecules to form an aqueous solution. Once dissolved in water, these solutes are more likely to come in contact with one another and therefore take part in chemical reactions that sustain life. In terms of its molecular structure, water is a small polar molecule with a bent shape formed by the polar covalent bonds of two hydrogen (H) atoms to one oxygen (O) atom (H2O). Because the O–H bonds are polar, the oxygen atom has a slight negative charge and the two hydrogen atoms have a slight positive charge. This polar property of water allows it to attract other water molecules via hydrogen bonds, which makes water cohesive. Surface tension results from the cohesive force due to the attraction between molecules at the surface of the liquid. Water is also adhesive as it is able to adhere to the surface of any polar or charged non-water molecules. Water is denser as a liquid than it is as a solid (or ice). This unique property of water allows ice to float above liquid water such as ponds, lakes, and oceans, thereby insulating the liquid below from the cold air above. Water has the capacity to absorb energy, giving it a higher specific heat capacity than other solvents such as ethanol. Thus, a large amount of energy is needed to break the hydrogen bonds between water molecules to convert liquid water into water vapor. As a molecule, water is not completely stable as each water molecule continuously dissociates into hydrogen and hydroxyl ions before reforming into a water molecule again. In pure water, the number of hydrogen ions balances (or equals) the number of hydroxyl ions, resulting in a pH that is neutral.",

Even at this stage, after a decade or so there is going to be a drastic change in whatever technology we are using around. Onto this note, along with the rise of communication technology the use of social media have risen to a different level. The main reason why people share information on social media is to reveal valuable and entertaining content to others, to grow and nourish relationships and to get the word about brands and interests they had love to use or support. All these factors have caused social media to evolve to keeping in touch with people around that could make a real impact on society. The domains of social media is being used in many ways that shape education, politics, culture, careers, innovation and many more things around. Therefore, social media has changed the way we live our lives. It has redefined the way we imagine our surroundings. Who could have imagined that community networking sites like Twitter, Instagram, Facebook and many more would become a major platform for brands to find potential customers.There are both positive and negative impacts of social media on society as well as businesses. Social media can impact you both positively and negatively. If you are a content creator, or a startup owner, then social media is a great platform for you to meet your customers and people around.

It is widely grown in the tropics and subtropics, important to both small and large commercial producers. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground. With this characteristic in mind, the botanist Carl Linnaeus gave peanuts the specific epithet hypogaea, which means \"under the earth\".\n\nThe peanut belongs to the botanical family Fabaceae (or Leguminosae), commonly known as the legume, bean, or pea family. Like most other legumes, peanuts harbor symbiotic nitrogen-fixing bacteria in root nodules. The capacity to fix nitrogen means peanuts require less nitrogen-containing fertilizer and improve soil fertility, making them valuable in crop rotations.\n\nPeanuts are similar in taste and nutritional profile to tree nuts such as walnuts and almonds, and, as a culinary nut, are often served in similar ways in Western cuisines.

        "evidence": "In his work, Caruana BIBREF4 proposed a multitask approach in which a learner takes advantage of the multiplicity of interdependent tasks while jointly learning them. The intuition is that if the tasks are correlated, the learner can learn a model jointly for them while taking into account the shared information which is expected to improve its generalization ability. People express their opinions online on various subjects (events, products..), on several languages and in several styles (tweets, paragraph-sized reviews..), and it is exactly this variety that motivates the multitask approaches. Specifically for Twitter for instance, the different settings of classification like binary, ternary and fine-grained are correlated since their difference lies in the sentiment granularity of the classes which increases while moving from binary to fine-grained problems.\nThere are two main decisions to be made in our approach: the learning algorithm, which learns a decision function, and the data representation. With respect to the former, neural networks are particularly suitable as one can design architectures with different properties and arbitrary complexity. Also, as training neural network usually relies on back-propagation of errors, one can have shared parts of the network trained by estimating errors on the joint tasks and others specialized for particular tasks. Concerning the data representation, it strongly depends on the data type available. For the task of sentiment classification of tweets with neural networks, distributed embeddings of words have shown great potential. Embeddings are defined as low-dimensional, dense representations of words that can be obtained in an unsupervised fashion by training on large quantities of text BIBREF10 .\nConcerning the neural network architecture, we focus on Recurrent Neural Networks (RNNs) that are capable of modeling short-range and long-range dependencies like those exhibited in sequence data of arbitrary length like text. While in the traditional information retrieval paradigm such dependencies are captured using INLINEFORM0 -grams and skip-grams, RNNs learn to capture them automatically BIBREF11 . To circumvent the problems with capturing long-range dependencies and preventing gradients from vanishing, the long short-term memory network (LSTM) was proposed BIBREF12 . In this work, we use an extended version of LSTM called bidirectional LSTM (biLSTM). While standard LSTMs access information only from the past (previous words), biLSTMs capture both past and future information effectively BIBREF13 , BIBREF11 . They consist of two LSTM networks, for propagating text forward and backwards with the goal being to capture the dependencies better. Indeed, previous work on multitask learning showed the effectiveness of biLSTMs in a variety of problems: BIBREF14 tackled sequence prediction, while BIBREF6 and BIBREF15 used biLSTMs for Named Entity Recognition and dependency parsing respectively.\nFigure FIGREF2 presents the architecture we use for multitask learning. In the top-left of the figure a biLSTM network (enclosed by the dashed line) is fed with embeddings INLINEFORM0 that correspond to the INLINEFORM1 words of a tokenized tweet. Notice, as discussed above, the biLSTM consists of two LSTMs that are fed with the word sequence forward and backwards. On top of the biLSTM network one (or more) hidden layers INLINEFORM2 transform its output. The output of INLINEFORM3 is led to the softmax layers for the prediction step. There are INLINEFORM4 softmax layers and each is used for one of the INLINEFORM5 tasks of the multitask setting. In tasks such as sentiment classification, additional features like membership of words in sentiment lexicons or counts of elongated/capitalized words can be used to enrich the representation of tweets before the classification step BIBREF3 . The lower part of the network illustrates how such sources of information can be incorporated to the process. A vector “Additional Features” for each tweet is transformed from the hidden layer(s) INLINEFORM6 and then is combined by concatenation with the transformed biLSTM output in the INLINEFORM7 layer.\nThere are two main decisions to be made in our approach: the learning algorithm, which learns a decision function, and the data representation.",

        "evidence": "Most avalanches occur spontaneously during storms under increased load due to snowfall and/or erosion. The second largest cause of natural avalanches is metamorphic changes in the snowpack such as melting due to solar radiation. Other natural causes include rain, earthquakes, rockfall and icefall. Artificial triggers of avalanches include skiers, snowmobiles, and controlled explosive work. Contrary to popular belief, avalanches are not triggered by loud sound; the pressure from sound is orders of magnitude too small to trigger an avalanche.\n\nAvalanche initiation can start at a point with only a small amount of snow moving initially; this is typical of wet snow avalanches or avalanches in dry unconsolidated snow. However, if the snow has sintered into a stiff slab overlying a weak layer then fractures can propagate very rapidly, so that a large volume of snow, that may be thousands of cubic metres, can start moving almost simultaneously.\n\nA snowpack will fail when the load exceeds the strength. The load is straightforward; it is the weight of the snow. However, the strength of the snowpack is much more difficult to determine and is extremely heterogeneous. It varies in detail with properties of the snow grains, size, density, morphology, temperature, water content; and the properties of the bonds between the grains. These properties may all metamorphose in time according to the local humidity, water vapour flux, temperature and heat flux. The top of the snowpack is also extensively influenced by incoming radiation and the local air flow. One of the aims of avalanche research is to develop and validate computer models that can describe the evolution of the seasonal snowpack over time. A complicating factor is the complex interaction of terrain and weather, which causes significant spatial and temporal variability of the depths, crystal forms, and layering of the seasonal snowpack.",

The Geological Society of America entitled its 2011 annual meeting: Archean to Anthropocene: The past is the key to the future. The new epoch has no agreed start-date, but one proposal, based on atmospheric evidence, is to fix the start with the Industrial Revolution c. 1780, with the invention of the steam engine. Other scientists link the new term to earlier events, such as the rise of agriculture and the Neolithic Revolution (around 12,000 years BP). Evidence of relative human impact – such as the growing human influence on land use, ecosystems, biodiversity, and species extinction – is substantial; scientists think that human impact has significantly changed (or halted) the growth of biodiversity. Those arguing for earlier dates posit that the proposed Anthropocene may have begun as early as 14,000–15,000 years BP, based on geologic evidence; this has led other scientists to suggest that \"the onset of the Anthropocene should be extended back many thousand years\";: 1  this would make the Anthropocene essentially synonymous with the current term, Holocene.",

It contains a two-staged CNN combined with query-based attention mechanism. Each stage comprises two major part: attention map and output representation.\nFig. FIGREF10 shows the architecture of the attention map in first stage CNN. We choose INLINEFORM0 sentence slice INLINEFORM1 in INLINEFORM2 , and apply CNN to it using the convolution kernel INLINEFORM3 , where superscript INLINEFORM4 denotes attention map, subscript INLINEFORM5 denotes the first stage CNN. Symbol INLINEFORM6 and INLINEFORM7 represent width of kernel and number of kernel respectively. The generated feature INLINEFORM8 is as follow: DISPLAYFORM0 \nwhere INLINEFORM0 is the bias. With INLINEFORM1 covering whole query and several words in the passage, convolution kernels would learn the query syntactic structure and give weight to each passage's location. That's why we use sigmoid function as activation function in this stage. Furthermore, we perform maxpooling to INLINEFORM2 perpendicularly in order to find the largest weight between different kernels in the same location, using maxpool kernel shaped INLINEFORM3 , and then generate word-level attention map INLINEFORM4 for each sentence.\nIn this stage, we want to acquire passage's sentence features based on the query and the choice respectively. We apply CNN to INLINEFORM0 to aggregate pattern of location relationship and acquire choice-based sentence features. Also, we apply CNN to INLINEFORM1 to acquire query-based sentence features. CNN architecture of output representation part Fig. FIGREF11 is similar to which of attention map part, but we use different kernels INLINEFORM2 and different bias INLINEFORM3 : DISPLAYFORM0 \nwhere the superscript INLINEFORM0 denotes output representation. We apply INLINEFORM3 on INLINEFORM4 and INLINEFORM5 then finally generate INLINEFORM6 and INLINEFORM7 using eq.4. We then multiply INLINEFORM8 by the word-level attention map INLINEFORM9 which comes from stage 2.2.1 element-wise through the first dimension.

        "question": "What is a contrastive translation?",
        "answer": "A contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one.",
        "evidence": "We automatically create a test set from the OpenSubtitles corpus BIBREF22 . The goal is to provide a large number of difficult test cases where an English pronoun has to be translated to a German pronoun.\nThe most challenging cases are translating it to either er, sie or es, depending on the grammatical gender of the antecedent. Not only is the translation of it ambiguous, there is also class imbalance in the training data (see Table TABREF18 ). There is roughly a 30% probability that it is aligned to es, which makes it difficult to learn to translate er and sie. We use parsing and automatic co-reference resolution to find translation pairs that satisfy our constraints.\nTo provide a basis for filtering with constraints, we tokenize the whole data set with the Moses tokenizer, generate symmetric word alignments with fast_align BIBREF23 , parse the English text with CoreNLP BIBREF24 , parse the German text with ParZu BIBREF25 and perform coreference resolution on both sides. The coreference chains are obtained with the neural model of CoreNLP for English, and with CorZu for German BIBREF26 , respectively.\nThen we opt for high-precision, aggressive filtering, according to the following protocol: for each pair of sentences INLINEFORM0 in English and German, extract iff\n INLINEFORM0 contains the English pronoun it, and INLINEFORM1 contains a German pronoun that is third person singular (er, sie or es), as indicated by their part-of-speech tags;\nthose pronouns are aligned to each other;\nboth pronouns are in a coreference chain;\ntheir nominal antecedents in the coreference chain are aligned on word level.\nThis removes most candidate pairs, but is necessary to overcome the noise introduced by our preprocessing pipeline, most notably coreference resolution. From the filtered set, we create a balanced test set by randomly sampling 4000 instances of each of the three translations of it under consideration (er, sie, es). We do not balance antecedent distance. See Table TABREF25 for the distribution of pronoun pairs and antecedent distance in the test set.\nFor each sentence pair in the resulting test set, we introduce contrastive translations. A contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one. For an example, see Table TABREF19 , where the pronoun it in the original translation corresponds to sie because the antecedent bat is a feminine noun in German (Fledermaus). We produce wrong translations by replacing sie with one of the other pronouns (er, es).\nNote that, by themselves, these contrastive translations are grammatically correct if the antecedent is outside the current sentence. The test set also contains pronouns with an antecedent in the same sentence (antecedent distance 0). Those examples do not require any additional context for disambiguation and we therefore expect the sentence-level baseline to perform well on them.\nWe take extra care to ensure that the resulting contrastive translations are grammatically correct, because ungrammatical sentences are easily dismissed by an NMT system. For instance, if there are any possessive pronouns (such as seine) in the sentence, we also change their gender to match the personal pronoun replacement.\nThe German coreference resolution system does not resolve es because most instances of es in German are either non-referential forms, or they refer to a clause instead of a nominal antecedent. We limit the test set to nominal antecedents, as these are the only ambiguous cases with respect to translation. For this reason, we have to rely entirely on the English coreference links for the extraction of sentence pairs with it INLINEFORM0 es, as opposed to pairs with it INLINEFORM1 er and it INLINEFORM2 sie where we have coreference chains in both languages.\nOur extraction process respects document boundaries, to ensure we always search for the right context. We extract additional information from the annotated documents, such as the distance (in sentences) between pronouns and their antecedents, the document of origin, lemma, morphology and dependency information if available.\nA contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one.",

        "evidence": "Knowledge Base Question Answering (KBQA) systems answer questions by obtaining information from KB tuples BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 . For an input question, these systems typically generate a KB query, which can be executed to retrieve the answers from a KB. Figure 1 illustrates the process used to parse two sample questions in a KBQA system: (a) a single-relation question, which can be answered with a single $<$ head-entity, relation, tail-entity $>$ KB tuple BIBREF6 , BIBREF7 , BIBREF2 ; and (b) a more complex case, where some constraints need to be handled for multiple entities in the question. The KBQA system in the figure performs two key tasks: (1) entity linking, which links $n$ -grams in questions to KB entities, and (2) relation detection, which identifies the KB relation(s) a question refers to.\nThe main focus of this work is to improve the relation detection subtask and further explore how it can contribute to the KBQA system. Although general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection. First, in most general relation detection tasks, the number of target relations is limited, normally smaller than 100. In contrast, in KBQA even a small KB, like Freebase2M BIBREF2 , contains more than 6,000 relation types. Second, relation detection for KBQA often becomes a zero-shot learning task, since some test instances may have unseen relations in the training data. For example, the SimpleQuestions BIBREF2 data set has 14% of the golden test relations not observed in golden training tuples. Third, as shown in Figure 1 (b), for some KBQA tasks like WebQuestions BIBREF0 , we need to predict a chain of relations instead of a single relation. This increases the number of target relation types and the sizes of candidate relation pools, further increasing the difficulty of KB relation detection. Owing to these reasons, KB relation detection is significantly more challenging compared to general relation detection tasks.\nThis paper improves KB relation detection to cope with the problems mentioned above. First, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching. Second, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations. Third, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information. Finally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching.\nIn order to assess how the proposed improved relation detection could benefit the KBQA end task, we also propose a simple KBQA implementation composed of two-step relation detection. Given an input question and a set of candidate entities retrieved by an entity linker based on the question, our proposed relation detection model plays a key role in the KBQA process: (1) Re-ranking the entity candidates according to whether they connect to high confident relations detected from the raw question text by the relation detection model. This step is important to deal with the ambiguities normally present in entity linking results. (2) Finding the core relation (chains) for each topic entity selection from a much smaller candidate entity set after re-ranking. The above steps are followed by an optional constraint detection step, when the question cannot be answered by single relations (e.g., multiple entities in the question). Finally the highest scored query from the above steps is used to query the KB for answers.\nOur main contributions include: (i) An improved relation detection model by hierarchical matching between questions and relations with residual learning; (ii) We demonstrate that the improved relation detector enables our simple KBQA system to achieve state-of-the-art results on both single-relation and multi-relation KBQA tasks.\nFirst, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching.",

        "question": "Whether the methodology used to create the data can later be used to create even larger datasets when the need arises?",
        "answer": "Yes.",
        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nFurthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.",

        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nIn particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities.",

        "evidence": "Le Souvenir français is a French association for maintaining war memorials and war memory, comparable to the Commonwealth War Graves Commission.\n\nMédaille du Souvenir Français.gif\nIt was created in 1887 in the departments of Alsace and Lorraine. Young women in traditional dress had been furtively placing cockades on soldiers' tombs. An Alsatian professor, Xavier Niessen, against Prussian orders in these departments, was keen to show his membership of the French fatherland and thought that remembering those who had died for France allowed the feeling of national unity to be maintained. Thus, on 7 March 1888 he summoned the French to join his new association, which then had a highly active period.\n\nIt is one of France's oldest associations d’utilité publique (being recognised as such on 1 February 1906) and has three aims:\n\nto conserve the memory of those who have died for France\nto maintain memorials to France's war dead\nto hand down the memory of them to future generations\nMany of its supporters were mobilised in the First World War, with the remaining ones looking after war graves and accompanying the families of the war dead on visits to them. The association was then in charge of 88,000 burials from the Franco-Prussian War and could only handle 1,700,000 burials of dead from the First World War. Thus the law of 31 July 1920 created the \"service national des sépultures\", took charge of military cemeteries and organised nationals necropolises. After the Second World War general Lacapelle, president of Le Souvenir Français, demanded the identification of 100,000 French soldiers who had died the battle of France and the maintenance of their tombs.\n\nIt has a general delegation by department, around 1,450 local committees in France and 52 foreign delegations.

Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach.",

        "answer": "To transfer monolingual NLG supervision to other pre-trained languages by fine-tuning.",
        "evidence": "Learning natural language generation (NLG) models heavily relies on annotated training data. However, most available datasets are collected in a single language (typically English), which restricts deploying the applications to other languages. In this work, we aim at transferring the supervision of a monolingual NLG dataset to unseen languages, so that we can boost performance for the low-resource settings.\nVarious methods have been proposed over the years to learn universal cross-lingual word embeddings BIBREF0, BIBREF1, BIBREF2 or sentence encoders BIBREF3, BIBREF4, BIBREF5, which tries to encode multilingual texts into a single shared vector space. Despite achieving promising results on cross-lingual classification problems, cross-lingual pre-trained models purposed for NLG tasks remains relatively understudied.\nThe cross-lingual generation problem is challenging due to the following reasons. First, it requires the models to understand multilingual input texts, and generate multilingual target sequences. So both encoder and decoder should be pre-trained together. Second, the many-to-many nature of cross-lingual NLG increases language pairs with the square of the number of languages. Third, the prediction space of cross-lingual NLG is much larger than classification tasks, which makes the knowledge transfer of decoders quite critical.\nPrevious work mainly relies on machine translation (MT) systems to map texts to different languages. The first strand of research directly uses MT in a pipeline manner BIBREF6. For example, the input written in other languages is first translated to English, and fed into the NLG model that is trained by English data. Then the generated English text is translated back to the target language. Another strand of work employs MT to generate pseudo training data for other language pairs that are lack of annotations BIBREF7, BIBREF8. However, such methods have to use multiple MT systems, which renders them suffering from error propagation. Moreover, because the pipeline-based methods do not explicitly share the same parameter space across the languages, we can not directly transfer the task-specific supervision to other low-resource languages.\nIn this paper, we propose a cross-lingual pre-trained model (named as Xnlg) in order to transfer monolingual NLG supervision to other pre-trained languages by fine-tuning. Specifically, Xnlg shares the same sequence-to-sequence model across languages, and is pre-trained with both monolingual and cross-lingual objectives. The model not only learns to understand multilingual input, but also is able to generate specific languages by conditioning on the encoded semantics. Figure FIGREF2 demonstrates how to use Xnlg to perform cross-lingual transfer for downstream tasks. The proposed model enables us to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation. Besides, we explore several fine-tuning strategies to make a compromise between cross-lingual ability and task ability. In addition, we introduce two cross-lingual NLG datasets (i.e., question generation, and abstractive summarization) for evaluation, which includes three languages, namely English, Chinese, and French. Experimental results on the NLG tasks show that Xnlg achieves competitive performance compared with the machine-translation-based pipeline model in zero-shot cross-lingual settings.\nIn this paper, we propose a cross-lingual pre-trained model (named as Xnlg) in order to transfer monolingual NLG supervision to other pre-trained languages by fine-tuning.",

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nOur key contributions are as follows: we introduce the first approach to context-aware machine translation using only monolingual document-level data; our approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation; we show which discourse phenomena are hard to capture using monolingual data only.",

The King is just one of sixteen pieces that each player can use during the game. The other fifteen pieces include: Eight pawns, two rooks, two knights, two bishops, and a queen. The pieces are placed on an eight by eight, square board in a fixed starting position. The game begins by the player using the white pieces moving one of their pieces to another square. Each player will then alternate playing one move turns. Each piece has a set of legal moves that it can perform. For example, a bishop can only move diagonally on squares of its same color, whereas rooks can only move vertically or horizontally. The goal of the game is to use your pieces in a strategic manner that ultimately leads to your opponent's King being captured. The most common way to achieve this is by using your pieces to capture your opponent's pieces that are defending the King, and then exploiting this weakness to attack the King. While it's important to play on the offensive, it's equally as important to understand your opponent's strategy, so that you can properly defend against their attempts to capture your own King.",

Recently, unsupervised MT BIBREF8, BIBREF9, BIBREF0, BIBREF10, BIBREF11, which can immensely reduce the reliance on parallel corpora, has been gaining more and more interest.\nTraining cross-lingual word embeddings BIBREF0, BIBREF12 is always the first step of the unsupervised MT models which produce a word-level shared embedding space for both the source and target, but the lexical coverage can be an intractable problem. To tackle this issue, BIBREF13 provided a subword-level solution to overcome the out-of-vocabulary (OOV) problem.\nIn this work, the systems we implement for the German-Czech language pair are built based on the previously proposed unsupervised MT systems, with some adaptations made to accommodate the morphologically rich characteristics of German and Czech BIBREF14. Both word-level and subword-level neural machine translation (NMT) models are applied in this task and further tuned by pseudo-parallel data generated from a phrase-based statistical machine translation (PBSMT) model, which is trained following the steps proposed in BIBREF10 without using any parallel data. We propose to train BPE embeddings for German and Czech separately and align those trained embeddings into a shared space with MUSE BIBREF0 to reduce the combinatorial explosion of word forms for both languages. To ensure the fluency and consistency of translations, an additional Czech language model is trained to select the translation candidates generated through beam search by rescoring them. Besides the above, a series of post-processing steps are applied to improve the quality of final translations. Our contribution is two-fold:\nWe propose a method to combine word and subword (BPE) pre-trained input representations aligned using MUSE BIBREF0 as an NMT training initialization on a morphologically-rich language pair such as German and Czech.\nWe study the effectiveness of language model rescoring to choose the best sentences and unknown word replacement (UWR) procedure to reduce the drawback of OOV words.\nThis paper is organized as follows: in Section SECREF2, we describe our approach to the unsupervised translation from German to Czech. Section SECREF3 reports the training details and the results for each steps of our approach. More related work is provided in Section SECREF4. Finally, we conclude our work in Section SECREF5.\nWe propose a method to combine word and subword (BPE) pre-trained input representations aligned using MUSE as an NMT training initialization on a morphologically-rich language pair such as German and Czech.",

        "question": "Extract the factors that affect the shape of a yield curve, and list them using bullets.",
        "evidence": "Yield curves are usually upward sloping asymptotically: the longer the maturity, the higher the yield, with diminishing marginal increases (that is, as one moves to the right, the curve flattens out). According to columnist Buttonwood of The Economist newspaper, the slope of the yield curve can be measured by the difference, or \"spread\", between the yields on two-year and ten-year U.S. Treasury Notes. A wider spread indicates a steeper slope. \n\nThere are two common explanations for upward sloping yield curves. First, it may be that the market is anticipating a rise in the risk-free rate. If investors hold off investing now, they may receive a better rate in the future. Therefore, under the arbitrage pricing theory, investors who are willing to lock their money in now need to be compensated for the anticipated rise in rates—thus the higher interest rate on long-term investments. Another explanation is that longer maturities entail greater risks for the investor (i.e. the lender). A risk premium is needed by the market, since at longer durations there is more uncertainty and a greater chance of events that impact the investment. This explanation depends on the notion that the economy faces more uncertainties in the distant future than in the near term. This effect is referred to as the liquidity spread. If the market expects more volatility in the future, even if interest rates are anticipated to decline, the increase in the risk premium can influence the spread and cause an increasing yield.\n\nThe opposite situation can also occur, in which the yield curve is \"inverted\", with short-term interest rates higher than long-term. For instance, in November 2004, the yield curve for UK Government bonds was partially inverted. The yield for the 10-year bond stood at 4.68%, but was only 4.45% for the 30-year bond. The market's anticipation of falling interest rates causes such incidents. Negative liquidity premiums can also exist if long-term investors dominate the market, but the prevailing view is that a positive liquidity premium dominates, so only the anticipation of falling interest rates will cause an inverted yield curve. Strongly inverted yield curves have historically preceded economic recessions.\n\nThe shape of the yield curve is influenced by supply and demand: for instance, if there is a large demand for long bonds, for instance from pension funds to match their fixed liabilities to pensioners, and not enough bonds in existence to meet this demand, then the yields on long bonds can be expected to be low, irrespective of market participants' views about future events.",
        "answer": "- The market's expectation of the future interest rate. If investors expect a higher interest rate in the future, then the curve would be upward sloping. Otherwise if the market is anticipating a falling interest rate, then the curve would be downward sloping.\n- Risk premium. Longer maturities entail greater risks for the investor, thus investors would expect a higher return for longer term investments.\n- Supply and demand. If there is a higher demand or lower supply for bonds with a certain maturity, then the yield for those bonds would go down.",

        "evidence": "Arc'teryx\n\nArc'teryx is a Canadian high-end design company specializing in outdoor apparel and equipment headquartered in North Vancouver, British Columbia. It focuses on technical apparel for mountaineering and Alpine sports, including related accessories. The company's name and logo reference the Archaeopteryx, the transitional fossil of early dinosaurs to modern dinosaurs (birds). Arc'teryx is known for their waterproof Gore-Tex shell jackets, knitwear, and down parkas.\n\nFounded in 1989 as Rock Solid, the company re-branded in 1991 as Arc'teryx to produce outerwear and climbing gear for the Coast Mountains in Canada. The company was sold to Salomon Group in 2001 and Amer Sports in 2005. Arc'teryx maintains two divisions: Veilance, their luxury streetwear retailer and LEAF, their retailer of technical gear for law enforcement and military forces.\n\nThe company is a major influence in the \"gorpcore\" and \"normcore\" fashion movements, the wearing of minimalist, outdoor apparel in urban settings.\n\nHistory\n\nAn Arc'teryx boutique on Mercer Street, London in July 2016\nOriginally named \"Rock Solid\" by founder Dave Lane, the company's first line of products was climbing gear. Dave Lane sold his 50% interest to Blair Murdoch and Tim Duholke who became silent partners in 1989. Then-principal Jeremy Guard changed the company name to Arc'teryx in 1991 to reflect the company's vision of creating disruptive \"evolutionary\" innovation within the outdoor products industry. Guard was president and principal of the company from 1991 to 2001. Using a heat laminate (thermolamination) technology, the partners designed and marketed the Vapor harness, which would become the company's most popular item. In 1993, after a series of relocations and staff additions, Arc'teryx released the Bora backpack using the same Vapor technology. In 1996, the company introduced technical apparel featuring Gore-Tex after obtaining a license from W. L. Gore & Associates. Arc'teryx re-located its headquarters to Burnaby, British Columbia in 1999 and then to North Vancouver in 2005.\n\nIn 2001, Arc'teryx was purchased by Salomon Group, a French subsidiary of the German retailer Adidas. In 2005, Arc'teryx was sold to Finnish retailer Amer Sports. In 2019, Chinese retailer Anta Sports bought a controlling stake (56%) in Amer. The Arc'teryx head office is located in North Vancouver and harnesses, backpacks, and other apparel is made in its own factory in New Westminster, BC. As their apparel line expanded Arc'teryx began manufacturing in international markets, specifically in China, the Philippines, Vietnam, Bangladesh, El Salvador, Laos, and Greece.\n\nJon Hoerauf joined the company as president in 2012, assuming the additional role of general manager in 2016. During the early 2020s, Arc'teryx co-produced items with high-fashion brands and designers which expanded their consumer market beyond outdoor enthusiasts.\n\nDivisions\nVeilance\nArc'teryx launched their luxury formal urban-wear brand in 2009, branded as Arc'teryx Veilance.\n\nLEAF\nArc'teryx's Law Enforcement and Armed Forces (LEAF) line is aimed at the military and police market. In the consumer and Internet market, it is often referred to as \"military birds\". Some of the collections are designed for their civilian counterparts, while others, such as Arc'teryx's Tango and Charlie backpacks, feature camouflage designs that are entirely geared toward the military. In contrast, military bird products use dark colors and military colors. Only a handful of products, such as the Alpha jacket, are currently made in Canada, while the rest, such as Assault Shirt, are made overseas, such as in El Salvador and Vietnam.\n\nSubculture\nArc'teryx has become widely popular in the street fashion scene and Internet culture. The theft (\"racking\") of Arc'teryx and other Gore-Tex items is considered to be part of the street subculture. It is seen as a high-end status symbol among youth, \"just shy of Stone Island and Moncler.\" The Atlantic noted the brand as selling \"premium-tier outdoorsiness\" while the Financial Times noted one of their largest demographics as \"urbanites\" in 2022.\n\nLabeled a cult brand by Fast Company in 2021, Arc'teryx is worn by \" hikers and hype-beasts\" according to The New York Times.\n\nThe company is a major influence in the \"gorpcore\" and \"normcore\" fashion movements – the wearing of minimalist, outdoor apparel in urban settings, along with Mammut, REI, Marmot and Patagonia.\n\nThroughout 2022, a TikTok trend emerged where individuals would shower, fully clothed with an Arc'teryx jacket, as British rapper YT's song \"Arc'teryx\" played on background.",

Hence, it is difficult to construct a gold standard (usually a reference set) to evaluate a response which is generated by an open domain chit-chat system. For the task-oriented system, although there are some objective evaluation metrics, such as the number of turns in a dialogue, the ratio of task completion, etc., there is no gold standard for automatically evaluating two (or more) dialogue systems when considering the satisfaction of the human and the fluency of the generated dialogue.\nFor the task-oriented system, although there are some objective evaluation metrics, such as the number of turns in a dialogue, the ratio of task completion, etc., there is no gold standard for automatically evaluating two (or more) dialogue systems when considering the satisfaction of the human and the fluency of the generated dialogue.",

        "evidence": "We use the bilingual neural-based Unsupervised Word Segmentation (UWS) approach from BIBREF6 to discover words in Mboshi. In this approach, Neural Machine Translation (NMT) models are trained between language pairs, using as source language the translation (word-level) and as target, the language to document (unsegmented phonemic sequence). Due to the attention mechanism present in these networks BIBREF7, posterior to training, it is possible to retrieve soft-alignment probability matrices between source and target sequences. These matrices give us sentence-level source-to-target alignment information, and by using it for clustering neighbor phonemes aligned to the same translation word, we are able to create segmentation in the target side. The product of this approach is a set of (discovered-units, translation words) pairs.\nIn this work we apply two simple methods for including multilingual information into the bilingual models from BIBREF6. The first one, Multilingual Voting, consists of merging the information learned by models trained with different language pairs by performing a voting over the final discovered boundaries. The voting is performed by applying an agreement threshold $T$ over the output boundaries. This threshold balances between accepting all boundaries from all the bilingual models (zero agreement) and accepting only input boundaries discovered by all these models (total agreement). The second method is ANE Selection. For every language pair and aligned sentence in the dataset, a soft-alignment probability matrix is generated. We use Average Normalized Entropy (ANE) BIBREF8 computed over these matrices for selecting the most confident one for segmenting each phoneme sequence. This exploits the idea that models trained on different language pairs will have language-related behavior, thus differing on the resulting alignment and segmentation over the same phoneme sequence.\nLastly, following the methodology from BIBREF8, we extract the most confident alignments (in terms of ANE) discovered by the bilingual models. Table presents the top 10 most confident (discovered type, translation) pairs. Looking at the pairs the bilingual models are most confident about, we observe there are some types discovered by all the bilingual models (e.g. Mboshi word itua, and the concatenation oboá+ngá). However, the models still differ for most of their alignments in the table. This hints that while a portion of the lexicon might be captured independently of the language used, other structures might be more dependent of the chosen language. On this note, BIBREF11 suggests the notion of word cannot always be meaningfully defined cross-linguistically.\nFLOAT SELECTED: Table 3: Top 10 confident (discovered type, translation) pairs for the five bilingual models.

        "evidence": "Word Sense Disambiguation (WSD) is an important problem in Natural Language Processing (NLP), both in its own right and as a stepping stone to other advanced tasks in the NLP pipeline, applications such as machine translation BIBREF0 and question answering BIBREF1 . WSD specifically deals with identifying the correct sense of a word, among a set of given candidate senses for that word, when it is presented in a brief narrative (surrounding text) which is generally referred to as context. Consider the ambiguous word `cold'. In the sentence “He started to give me a cold shoulder after that experiment”, the possible senses for cold can be cold temperature (S1), a cold sensation (S2), common cold (S3), or a negative emotional reaction (S4). Therefore, the ambiguous word cold is specified along with the sense set {S1, S2, S3, S4} and our goal is to identify the correct sense S4 (as the closest meaning) for this specific occurrence of cold after considering - the semantic and the syntactic information of - its context.\nIn this effort, we develop our supervised WSD model that leverages a Bidirectional Long Short-Term Memory (BLSTM) network. This network works with neural sense vectors (i.e. sense embeddings), which are learned during model training, and employs neural word vectors (i.e. word embeddings), which are learned through an unsupervised deep learning approach called GloVe (Global Vectors for word representation) BIBREF2 for the context words. By evaluating our one-model-fits-all WSD network over the public gold standard dataset of SensEval-3 BIBREF3 , we demonstrate that the accuracy of our model in terms of F-measure is comparable with the state-of-the-art WSD algorithms'.\nWe outline the organization of the rest of the paper as follows. In Section 2, we briefly explore earlier efforts in WSD and discuss recent approaches that incorporate deep neural networks and word embeddings. Our main model that employs BLSTM with the sense and word embeddings is detailed in Section 3. We then present our experiments and results in Section 4 supported by a discussion on how to avoid some drawbacks of the current model in order to achieve higher accuracies and demand less number of training data which is desirable. Finally, in Section 5, we conclude with some future research directions for the construction of sense embeddings as well as applications of such model in other domains such as biomedicine.\nBy evaluating our one-model-fits-all WSD network over the public gold standard dataset of SensEval-3 , we demonstrate that the accuracy of our model in terms of F-measure is comparable with the state-of-the-art WSD algorithms'.",

        "question": "Whether the improvement is mainly due to Synperiodic filter bank alone or Synperiodic filter bank +  new structure?",
        "answer": "In our first version submission, we have conducted two ablation studies (shown in Table 2) 1. We replace SELDNet, EIN and SoundDet front-end head with our proposed synperiodic filter bank. Experimental result shows that introducing synperiodic filter bank to existing approaches helps to improve their corresponding performance. It thus shows our proposed synperiodic filter bank can be used as a plug-and-play front-end by existing approaches to improve their performance on sound source detection task, without introducing explicit extra parameters and computational burden. 2. Moreover, we test five variants of synperiodic filter bank. For example, we find out that reducing the multi-scale perception strategy of synperiodic filter bank to single-scale perception in either time domain or frequency domain reduces the performance. This internal synperiodic filter bank variants ablation study shows the necessity of each part of synperiodic filter bank design. To disentangle the synperiodic filter bank front-end and Transformer-like backbone, in our revised paper, we have added another ablation study (also given in Table 2), in which we replace our proposed SoundSynp's synperiodic filter bank with traditional hand-engineered features including MFCC and LogMel. The corresponding experimental result shows that using traditional sound features leads to inferior performance. In sum, we can conclude from the three ablation studies that: *  The performance improvement is due to the joint contribution of synperiodic filter bank and Transformer-like backbone network structure. *  Removing either Transformer-like backbone network (ablation study 1) or synperiodic filter bank (ablation study 2) inevitably reduces the performance. * Transformer-like backbone network and synperiodic filter bank can be disentangled to solve other sound related tasks separately.",
        "evidence": "We adopt two evaluation metrics: segment-based and event-based metric. Segment-based metric is a widely adopted evaluation metric, it couples semantic label and spatial location together: a semantic-correctly detected sound source needs to be spatially close enough to its ground truth location in order to be regarded as a true positive detection. Event-based based metric is newly proposed by to comprehensively evaluate under different confidence scores. Like object detection from images, it computes mean average precision (mAP) and mean average recall (mAR) score.\nWe call our framework SoundSynp and compare it with four most recent methods: SELD-Net, EIN, SoundDet and Utsc-Iflytek. SELDNet is the baseline model and it jointly trains sound source's semantic label and spatial location with a convolutional recurrent neural network (CRNN). EIN) is a very recent work. It adopts multi-heads self-attention to model temporal dependency and trackwise permutation-invariant training to train the model. SoundDet directly learns from raw waveform with MaxCorr kernels, followed by an encoder-decoder neural network. Utsc-Iflytek is ranked first in DECASE2020 challenge leaderboard 1 , it combines MIC and FOA features and ensembles different models like ResNet and Xception(Chollet, 2017) to give final prediction.\nThe network architecture is shown in table in Appendix material. To train the neural network, we evenly divide the one minute long four-channel raw waveform into non-overlapping 4s short snippets. The raw waveform is first normalized to r´1, 1s before feeding the neural network. We adopt Adam optimizer with an initial learning rate 0.0002 in the first 100 epochs and 0.00007 in the following 50 epochs. Batchsize is 16. The loss combination weight between classification head and regression head is 1 : 2. During training, data augmentation method SpecAugment is applied. For DoA task, we regress direction of arrival angle in Cartesian coordinates rx, y, zs. In synperiodic filter bank groups, the filter length is 1025, each group's filter number is 256 and the step size is 600. Particularly, we have observed the initialized learnable synperiodic filter banks update its parameters intensively during the very early several epochs, and then gradually becomes stable. The final learned parameters are close to their initialization, one group's learned parameters (like frequency response and filter window length) is different from those learned by other groups, although they are initialized as the same in the start. We train each model five times independently and report the average score. The standard deviation is within 0.04 (for recall) and 0.2 ˝for angle, 0.003 for mAP and mAR.\nThe result is given in Table1, from which we see that SoundSynp achieves the best performance over all comparing methods by a large margin, under both segment-based and event-based metrics. Both SELDNet, EIN and UTSC-Iflytek use pre-extracted hand-engineered sound features, such as Logmel, GCC-Phat and Intensity Vector. SoundDet and SoundSynp are the only two methods that directly learn from raw waveforms. At the same time, SoundSynp obtains better performance on FOA than MIC format, the same phenomena has been observed by all other methods. It thus shows FOA better fits for sound source detection than MIC. It is worth noting that Utsc-Iflytek ensembles different powerful image-based 2D models to detect sound sources. However, our proposed SoundSynp still outperforms Utsc-Iflytek by a large margin. We don't report of mAP/mAR value for Utsc-Iflytek because it is a complex system and no detail about their system is available.\nAblation Study To disentangle the individual contribution of each part of our SoundSynp framework to the whole performance improvement, we conduct three ablation studies. First, the individual contribution of Synperiodic filter bank. We replace hand-engineered sound feature head of SELDNet, EIN and learnable MaxCorr filter bank with our proposed Synperiodic filter bank to test their corresponding performance. It helps to remove the influence of the backbone neural network of different models and thus helps to get direct comparison of synperiodic filter bank with other front-end. Second, we replace SoundSynp's synperiodic filter bank group with widely-used MFCC and Log-Mel that is used by and EIN, respectively. It disentangles synperiodic filter bank group with Transformer-like backbone, thus helps to figure out if the performance gain is simply brought by backbone network.\nThird, internally, we test five synperiodic variants: (1) synperiodic filter bank with just multiscale perception in frequency domain (SoundSynp MSFreq), (2) just multi-scale perception in time domain (SoundSynp MSTime), (3) Synperiodic filter bank with frequency responses linearly initialized in Nyquist frequency range (SoundSynp Linear, compare with our mel-scale initialization), (4) just one synperiodic filter bank without multi-scale perception neither in time nor frequency domain (SoundSynp SingleScale). () synperiodic filter bank with rectangular band-pass frequency response initialization (SoundSynp Sinc), like SincNet does. The internal comparison helps us to figure out the necessity of each part of synperiodic filter bank design.\nThe ablation study result is shown in Table. We can observe that: First, using synperiodic filter bank as a replacement of existing filter bank can help to improve the corresponding performance. Second, replacing SoundSynp's synperiodic filter bank with classic hand-engineered features inevitably reduces the performance under all evaluation metrics, its thus shows learning from pre-extracted fixed and single-scale sound representation leads to inferior performance than our proposed multiscale synperiodic filter bank. Third, the absence of multi-scale perception in either frequency domain or time domain inevitably reduces the performance. We find sound source semantic label detection suffers more in single-scale perception in time domain than in frequency domain (see better performance on ER 20 ˝, and F 20 ˝score), which shows frequency domain multi-scale perception is vital for semantic label estimation. Similarly, we can observe that multi-scale perception in time domain is vital for sound source spatial location estimation (see better performance on LE and LR score). Linearly initialized filter bank frequency response reduces the performance, which shows assigning more filters to the lower frequency range is important. But this conclusion might be data-dependent because we find DCASE dataset contains many low-frequency sounds like burning fire and footsteps. Moreover, reducing the synperiodic filter bank group to one groups with just singlescale perception leads to comparably the worst performance, it thus shows multi-scale perception in both time and frequency domain is essential for DoA-based sound source detection. Lastly, SoundSynp Sinc leads to slightly inferior performance than our used mel-scale initialization strategy, it shows our proposed synperiodic filter bank is a general filter bank that can be adopted to other frequency sensitive filter bank.  One qualitative comparison is shown in Fig.. We can clearly see that SELDNet generates mixed prediction at different time steps and DoA locations. SoundDet and EIN give non-existing sound sources (orange color). When multiple sound sources happen at the same time (polyphonicity), SoundDet and EIN are easily failed to predict the right spatial location (discretized blue and red color). Our method predicts more spatially and temporally consistent sound sources by maximally keeping sound source's continuity and consistency.\nWe adopt two evaluation metrics: segment-based and event-based metric. Segment-based metric is a widely adopted evaluation metric, it couples semantic label and spatial location together: a semantic-correctly detected sound source needs to be spatially close enough to its ground truth location in order to be regarded as a true positive detection.

The internal comparison helps us to figure out the necessity of each part of synperiodic filter bank design.\nThe ablation study result is shown in Table. We can observe that: First, using synperiodic filter bank as a replacement of existing filter bank can help to improve the corresponding performance. Second, replacing SoundSynp's synperiodic filter bank with classic hand-engineered features inevitably reduces the performance under all evaluation metrics, its thus shows learning from pre-extracted fixed and single-scale sound representation leads to inferior performance than our proposed multiscale synperiodic filter bank. Third, the absence of multi-scale perception in either frequency domain or time domain inevitably reduces the performance. We find sound source semantic label detection suffers more in single-scale perception in time domain than in frequency domain (see better performance on ER 20 ˝, and F 20 ˝score), which shows frequency domain multi-scale perception is vital for semantic label estimation. Similarly, we can observe that multi-scale perception in time domain is vital for sound source spatial location estimation (see better performance on LE and LR score). Linearly initialized filter bank frequency response reduces the performance, which shows assigning more filters to the lower frequency range is important. But this conclusion might be data-dependent because we find DCASE dataset contains many low-frequency sounds like burning fire and footsteps. Moreover, reducing the synperiodic filter bank group to one groups with just singlescale perception leads to comparably the worst performance, it thus shows multi-scale perception in both time and frequency domain is essential for DoA-based sound source detection. Lastly, SoundSynp Sinc leads to slightly inferior performance than our used mel-scale initialization strategy, it shows our proposed synperiodic filter bank is a general filter bank that can be adopted to other frequency sensitive filter bank.  One qualitative comparison is shown in Fig.. We can clearly see that SELDNet generates mixed prediction at different time steps and DoA locations. SoundDet and EIN give non-existing sound sources (orange color). When multiple sound sources happen at the same time (polyphonicity), SoundDet and EIN are easily failed to predict the right spatial location (discretized blue and red color). Our method predicts more spatially and temporally consistent sound sources by maximally keeping sound source's continuity and consistency.\nWe use Pyroomacoustics simulator to simulate a shoebox like room with r7m, 5m, 3ms size. Four microphones (24kHz sampling rate) are configured in a plane with 5cm mutual distance and put in the room center (r3.5m, 2.5m, 1.5ms). We choose three commonly heard sounds from BBC sound effect site 2 : cat meowing, baby talking and dog barking. All these seed sounds last less than 10s. During simulation, we put all seed sound in the plane z \" 1.5m (we constrain to a plane because we find relaxing z easily leads EIN model to get stuck in a local minima like r´1, ´1, ´1s), but with x randomly in r2m, 5ms and y randomly in r1m, 4ms, up to two sounds can happen at the same time. In sum, we have simulated 500 one-minute recordings (400 for train, 100 for test), with an average of four sounds recorded per recording. For physical location prediction, we regress the angle and range. The result is in Table. We do not report SELDNet result as we find it doesn't converge during train. We can see from the table that SoundSynp produces the best performance than over EIN and SoundDet network. Replacing their front-end with synperiodic filter bank also improves the performance. It thus shows our proposed SoundSynp is capable of learning representation for physical-location based sound source detection.\nTable 2: Ablation study report. Internally, we replace SELDNet, EIN and SoundDet head with\nsynperiodic filter bank (denoted as Synp). Externally, we test different modified SoundSynp versions.****Third, internally, we test five synperiodic variants: (1) synperiodic filter bank with just multiscale perception in frequency domain (SoundSynp MSFreq), (2) just multi-scale perception in time domain (SoundSynp MSTime), (3) Synperiodic filter bank with frequency responses linearly initialized in Nyquist frequency range (SoundSynp Linear, compare with our mel-scale initialization), (4) just one synperiodic filter bank without multi-scale perception neither in time nor frequency domain (SoundSynp SingleScale).

It thus shows our proposed SoundSynp is capable of learning representation for physical-location based sound source detection.****The computation time of all comparing methods is given in Table 5, from which we can see that our proposed SoundSynp framework requires between 2x-3x more computation time than SELDNet, EIN and SoundDet due to its large Transformer-like backbone. However, SoundSynp computation time is still within a controllable range.",

The left blocks and the right blocks form two QANets, each of which takes a document and a question as the input and outputs an answer. In QANet, firstly, an embedding encoder obtains word and character embeddings for each word in INLINEFORM0 or INLINEFORM1 and then models the temporal interactions between words and refines word vectors to contextualized word representations. All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention. The intuition here is that convolution components can model local interactions and self-attention components focus on modeling global interactions. The context-query attention layer generates the question-document similarity matrix and computes the question-aware vector representations of the context words. After that, a model encoder layer containing seven encoder blocks captures the interactions among the context words conditioned on the question.

Recruitment of participants with cognitive impairment has historically been a bottleneck in clinical trials BIBREF1 , making AD datasets relatively small.

Picture description using an image to elicit narrative discourse samples is one such task that has proved to be successful in detecting AD BIBREF2 . However, it is important to develop ML models of high performance that would produce results generalizable across different tasks.\nSeveral studies have used natural language processing and machine learning to distinguish between healthy and cognitively impaired speech of participants describing a picture. Fraser et al. BIBREF3 used linguistic and acoustic features to classify healthy and pathological speech transcripts with an accuracy of INLINEFORM0 . Similarly, Karlekar et al. BIBREF4 classified utterances of speakers as AD or healthy (HC) with an accuracy of INLINEFORM1 using an enlarged, utterance-level view of transcripts of picture descriptions. In line with previous research, we use linguistic and acoustic features of speech as input to our ML model. Furthermore, we extend the model to using data from several different tasks.\nNoorian et al. BIBREF5 demonstrated that using within-task data of healthy participants describing a picture improved AD detection performance by up to 13%.

We find that models trained on datasets of picture description tasks augmented with conversational speech of healthy speakers learn decision boundaries that are more generalizable across activities with lower out-of-task errors. We observe a 9% increase in AD detection performance when normative data from different tasks are utilized.

Hybrid performs sentence splitting and deletion operations based on discourse representation structures, and then simplifies sentences with PBMT-R BIBREF25 . SBMT-SARI BIBREF19 is syntax-based translation model using PPDB paraphrase database BIBREF26 and modifies tuning function (using SARI). We choose two neural text simplification systems. NMT is a basic attention-based encoder-decoder model which uses OpenNMT framework to train with two LSTM layers, hidden states of size 500 and 500 hidden units, SGD optimizer, and a dropout rate of 0.3 BIBREF8 . Dress is an encoder-decoder model coupled with a deep reinforcement learning framework, and the parameters are chosen according to the original paper BIBREF20 . For the experiments with synthetic parallel data, we back-translate a random sample of 60 000 sentences from the collected simplified sentences into ordinary sentences. Our model is trained on synthetic data and the available parallel data, denoted as NMT+synthetic.\nResults. Table 1 shows the results of all models on WikiLarge dataset. We can see that our method (NMT+synthetic) can obtain higher BLEU, lower FKGL and high SARI compared with other models, except Dress on FKGL and SBMT-SARI on SARI. It verified that including synthetic data during training is very effective, and yields an improvement over our baseline NMF by 2.11 BLEU, 1.7 FKGL and 1.07 SARI. We also substantially outperform Dress, who previously reported SOTA result. The results of our human evaluation using Simplicity are also presented in Table 1. NMT on synthetic data is significantly better than PBMT-R, Dress, and SBMT-SARI on Simplicity. It indicates that our method with simplified data is effective at creating simpler output.\nResults on WikiSmall dataset are shown in Table 2. We see substantial improvements (6.37 BLEU) than NMT from adding simplified training data with synthetic ordinary sentences. Compared with statistical machine translation models (PBMT-R, Hybrid, SBMT-SARI), our method (NMT+synthetic) still have better results, but slightly worse FKGL and SARI. Similar to the results in WikiLarge, the results of our human evaluation using Simplicity outperforms the other models. In conclusion, Our method produces better results comparing with the baselines, which demonstrates the effectiveness of adding simplified training data.\nWe choose three statistical text simplification systems. PBMT-R is a phrase-based method with a reranking post-processing step (Wubben et al., 2012). Hybrid performs sentence splitting and deletion operations based on discourse representation structures, and then simplifies sentences with PBMT-R (Narayan and Gardent, 2014). SBMT-SARI (Xu et al., 2016) is syntax-based translation model using PPDB paraphrase database (Ganitkevitch et al., 2013) and modifies tuning function (using SARI).",

Ranging from showing correlation between the main language features on Twitter and several demographic variables BIBREF10 , through predicting heart-disease rates of an area based on its language use BIBREF11 or relating unemployment to social media content and activity BIBREF12 , BIBREF13 , BIBREF14 to forecasting stock market moves from search semantics BIBREF15 , many studies have attempted to connect online media language and metadata to real-world outcomes. Various studies have analyzed spatial variation in the text of OSN messages and its applicability to several different questions, including user localization based on the content of their posts BIBREF16 , BIBREF17 , empirical analysis of the geographic diffusion of novel words, phrases, trends and topics of interest BIBREF18 , BIBREF19 , measuring public mood BIBREF20 .\nWhile many of the above cited studies exploit the fact that language use or social media activity varies in space, it is hard to capture the impact of the geographic environment on the used words or concepts. There is a growing literature on how the sheer size of a settlement influences the number of patents, GDP or the total road length driven by universal laws BIBREF21 .

By examining the so-called scaling exponents, we are able to connect geographical size effects to systematic variations in word use frequencies. We show that the sensitivity of words to population size is also reflected in their meaning. We also investigate how social media language and city size affects the parameters of Zipf's law BIBREF39 , and how the exponent of Zipf's law is different from that of the literature value BIBREF39 , BIBREF40 .

She had never seen such a brilliant treasure, it was the color of the rainbow, and when she looked closer it looked eerily similar to a dragon scale, but she couldn't believe that it was truly a dragon scale because they only existed in the stories she read. She looked around and spotted another shiny scale, like a trail of breadcrumbs leading her to the forest behind her house. She knew that her parents would want her to go to school but her curiosity got the better of her and she started to follow the trail of shiny scales to the forest. She fought her way through the forest until she came upon what looked like a cave that she was sure was not there before. She cautiously entered the cave and and instead of the cave getting darker, it was getting brighter, like a brilliant light was inside the cave. When she turned the corner in the cave, she saw the most beautiful sparkling dragon and could not believe her eyes! She slowly crept toward the dragon, who was watching her closely as she approached. She held out her hand as if to pet the dragon and the dragon sniffed her hand, then rubbed it's head on the bottom of her hand to signal that it wanted to befriend her. She giggled as the dragon purred and rubbed it's shiny body circling around her. The dragon then spoke and asked her if she had ever been to the beyond worlds. The girl shook her head, the dragon blinked her eyes and projected an image onto the cave wall to show one of the beautiful beyond worlds that was filled with dragons. The girl asked if the dragon would take her there, the dragon laughed and nodded, signaling for the girl to jump on it's back. The rush of excitement came over the girl, and she hopped on the dragons back. She held on tight as the dragon started running out of the cave, as the dragon exited the cave a portal opened and it leaped into the portal. The girl closed her eyes, not knowing what would happen next, she finally opened her eyes and gawked with amazement when they arrived in the beyond world, she could not believe what she was seeing, DRAGONS!

        "question": "Where does the comparative analysis applied?",
        "answer": "Speculation detection and scope resolution.",
        "evidence": "The task of speculation detection and scope resolution is critical in distinguishing factual information from speculative information. This has multiple use-cases, like systems that determine the veracity of information, and those that involve requirement analysis. This task is particularly important to the biomedical domain, where patient reports and medical articles often use this feature of natural language. This task is commonly broken down into two subtasks: the first subtask, speculation cue detection, is to identify the uncertainty cue in a sentence, while the second subtask: scope resolution, is to identify the scope of that cue. For instance, consider the example:\nIt might rain tomorrow.\nThe speculation cue in the sentence above is ‘might’ and the scope of the cue ‘might’ is ‘rain tomorrow’. Thus, the speculation cue is the word that expresses the speculation, while the words affected by the speculation are in the scope of that cue.\nThis task was the CoNLL-2010 Shared Task (BIBREF0), which had 3 different subtasks. Task 1B was speculation cue detection on the BioScope Corpus, Task 1W was weasel identification from Wikipedia articles, and Task 2 was speculation scope resolution from the BioScope Corpus. For each task, the participants were provided the train and test set, which is henceforth referred to as Task 1B CoNLL and Task 2 CoNLL throughout this paper.\nFor our experimentation, we use the sub corpora of the BioScope Corpus (BIBREF1), namely the BioScope Abstracts sub corpora, which is referred to as BA, and the BioScope Full Papers sub corpora, which is referred to as BF. We also use the SFU Review Corpus (BIBREF2), which is referred to as SFU.\nThis subtask of natural language processing, along with another similar subtask, negation detection and scope resolution, have been the subject of a body of work over the years. The approaches used to solve them have evolved from simple rule-based systems (BIBREF3) based on linguistic information extracted from the sentences, to modern deep-learning based methods. The Machine Learning techniques used varied from Maximum Entropy Classifiers (BIBREF4) to Support Vector Machines (BIBREF5,BIBREF6,BIBREF7,BIBREF8), while the deep learning approaches included Recursive Neural Networks (BIBREF9,BIBREF10), Convolutional Neural Networks (BIBREF11) and most recently transfer learning-based architectures like Bidirectional Encoder Representation from Transformers (BERT) (BIBREF12). Figures FIGREF1 and FIGREF1 contain a summary of the papers addressing speculation detection and scope resolution (BIBREF13, BIBREF5, BIBREF9, BIBREF3, BIBREF14, BIBREF15, BIBREF16, BIBREF17, BIBREF6, BIBREF11, BIBREF18, BIBREF10, BIBREF19, BIBREF7, BIBREF4, BIBREF8).\nInspired by the most recent approach of applying BERT to negation detection and scope resolution (BIBREF12), we take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT (BIBREF20), XLNet (BIBREF21) and RoBERTa (BIBREF22), applied to speculation detection and scope resolution. We evaluate the performance of each model across all datasets via the single dataset training approach, and report all scores including inter-dataset scores (i.e. train on one dataset, evaluate on another) to test the generalizability of the models. This approach outperforms all existing systems on the task of speculation detection and scope resolution. Further, we jointly train on multiple datasets and obtain improvements over the single dataset training approach on most datasets.\nContrary to results observed on benchmark GLUE tasks, we observe XLNet consistently outperforming RoBERTa. To confirm this observation, we apply these models to the negation detection and scope resolution task, and observe a continuity in this trend, reporting state-of-the-art results on three of four datasets on the negation scope resolution task.\nThe rest of the paper is organized as follows: In Section 2, we provide a detailed description of our methodology and elaborate on the experimentation details. In Section 3, we present our results and analysis on the speculation detection and scope resolution task, using the single dataset and the multiple dataset training approach. In Section 4, we show the results of applying XLNet and RoBERTa on negation detection and scope resolution and propose a few reasons to explain why XLNet performs better than RoBERTa. Finally, the future scope and conclusion is mentioned in Section 5.\nwe take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT, XLNet and RoBERTa, applied to speculation detection and scope resolution.",

We showcase the approach with the analysis of incident reports submitted in Imperial College Healthcare NHS Trust, London. The multiscale community structure reveals levels of meaning with different resolution in the topics of the dataset, as shown by relevant descriptive terms extracted from the groups of records, as well as by comparing a posteriori against hand-coded categories assigned by healthcare personnel. Our content communities exhibit good correspondence with well-defined hand-coded categories, yet our results also provide further medical detail in certain areas as well as revealing complementary descriptors of incidents beyond the external classification.

        "question": "Are they the first to combine retrieval and generative dialog systems?",
        "answer": "Yes.",
        "evidence": "Automatic dialog/conversation systems have served humans for a long time in various fields, ranging from train routing nbcitetrain to museum guiding nbcitemuseum. In the above scenarios, the dialogs are domain-specific, and a typical approach to such in-domain systems is by human engineering, for example, using manually constructed ontologies nbciteyoungsigdial, natural language templates nbcitetemplate, and even predefined dialog states nbcitestatetracking.\nRecently, researchers have paid increasing attention to open-domain, chatbot-style human-computer conversation, because of its important commercial applications, and because it tackles the real challenges of natural language understanding and generation nbciteretrieval1,acl,aaai. For open-domain dialogs, rules and temples would probably fail as we can hardly handle the great diversity of dialog topics and natural language sentences. With the increasing number of human-human conversation utterances available on the Internet, previous studies have developed data-oriented approaches in the open domain, which can be roughly categorized into two groups: retrieval systems and generative systems.\nWhen a user issues an utterance (called a query), retrieval systems search for a most similar query in a massive database (which consists of large numbers of query-reply pairs), and respond to the user with the corresponding reply nbciteretrieval1,retrieval2. Through information retrieval, however, we cannot obtain new utterances, that is, all replies have to appear in the database. Also, the ranking of candidate replies is usually judged by surface forms (e.g., word overlaps, tf $\\cdot $ idf features) and hardly addresses the real semantics of natural languages.\nGenerative dialog systems, on the other hand, can synthesize a new sentence as the reply by language models nbciteBoWdialog,acl,aaai. Typically, a recurrent neural network (RNN) captures the query's semantics with one or a few distributed, real-valued vectors (also known as embeddings); another RNN decodes the query embeddings to a reply. Deep neural networks allow complicated interaction by multiple non-linear transformations; RNNs are further suitable for modeling time-series data (e.g., a sequence of words) especially when enhanced with long short term memory (LSTM) or gated recurrent units (GRUs). Despite these, RNN also has its own weakness when applied to dialog systems: the generated sentence tends to be short, universal, and meaningless, for example, “I don't know” nbcitenaacl or “something” nbciteaaai. This is probably because chatbot-like dialogs are highly diversified and a query may not convey sufficient information for the reply. Even though such universal utterances may be suited in certain dialog context, they make users feel boring and lose interest, and thus are not desirable in real applications.\nIn this paper, we are curious if we can combine the above two streams of approaches for open-domain conversation. To this end, we propose an ensemble of retrieval and generative dialog systems. Given a user-issued query, we first obtain a candidate reply by information retrieval from a large database. The query, along with the candidate reply, is then fed to an utterance generator based on the “bi-sequence to sequence” (biseq2seq) model nbcitemultiseq2seq. Such sequence generator takes into consideration the information contained in not only the query but also the retrieved reply; hence, it alleviates the low-substance problem and can synthesize replies that are more meaningful. After that we use the scorer in the retrieval system again for post-reranking. This step can filter out less relevant retrieved replies or meaningless generated ones. The higher ranked candidate (either retrieved or generated) is returned to the user as the reply.\nFrom the above process, we see that the retrieval and generative systems are integrated by two mechanisms: (1) The retrieved candidate is fed to the sequence generator to mitigate the “low-substance” problem; (2) The post-reranker can make better use of both the retrieved candidate and the generated utterance. In this sense, we call our overall approach an ensemble in this paper. To the best of our knowledge, we are the first to combine retrieval and generative models for open-domain conversation.\nExperimental results show that our ensemble model consistently outperforms each single component in terms of several subjective and objective metrics, and that both retrieval and generative methods contribute an important portion to the overall approach. This also verifies the rationale for building model ensembles for dialog systems.\nTo the best of our knowledge, we are the first to combine retrieval and generative models for open-domain conversation.",

        "question": "What kind of method the proposed equation embeddings are?",

        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations.",

        "evidence": "Modeling temporal and sequential data, which is crucial in machine learning, can be applied in many areas, such as speech and natural language processing. Deep neural networks (DNNs) have garnered interest from many researchers after being successfully applied in image classification BIBREF0 and speech recognition BIBREF1 . Another type of neural network, called a recurrent neural network (RNN) is also widely used for speech recognition BIBREF2 , machine translation BIBREF3 , BIBREF4 and language modeling BIBREF5 , BIBREF6 . RNNs have achieved many state-of-the-art results. Compared to DNNs, they have extra parameters for modeling the relationships of previous or future hidden states with current input where the RNN parameters are shared for each input time-step.\nGenerally, RNNs can be separated by a simple RNN without gating units, such as the Elman RNN BIBREF7 , the Jordan RNN BIBREF8 , and such advanced RNNs with gating units as the Long-Short Term Memory (LSTM) RNN BIBREF9 and the Gated Recurrent Unit (GRU) RNN BIBREF4 . A simple RNN usually adequate to model some dataset and a task with short-term dependencies like slot filling for spoken language understanding BIBREF10 . However, for more difficult tasks like language modeling and machine translation where most predictions need longer information and a historical context from each sentence, gating units are needed to achieve good performance. With gating units for blocking and passing information from previous or future hidden layer, we can learn long-term information and recursively backpropagate the error from our prediction without suffering from vanishing or exploding gradient problems BIBREF9 . In spite of this situation, the concept of gating mechanism does not provide an RNN with a more powerful way to model the relation between the current input and previous hidden layer representations.\nMost interactions inside RNNs between current input and previous (or future) hidden states are represented using linear projection and addition and are transformed by the nonlinear activation function. The transition is shallow because no intermediate hidden layers exist for projecting the hidden states BIBREF11 . To get a more powerful representation on the hidden layer, Pascanu et al. BIBREF11 modified RNNs with an additional nonlinear layer from input to the hidden layer transition, hidden to hidden layer transition and also hidden to output layer transition. Socher et al. BIBREF12 , BIBREF13 proposed another approach using a tensor product for calculating output vectors given two input vectors. They modified a Recursive Neural Network (RecNN) to overcome those limitations using more direct interaction between two input layers. This architecture is called a Recursive Neural Tensor Network (RecNTN), which uses a tensor product between child input vectors to represent the parent vector representation. By adding the tensor product operation to calculate their parent vector, RecNTN significantly improves the performance of sentiment analysis and reasoning on entity relations tasks compared to standard RecNN architecture. However, those models struggle to learn long-term dependencies because the do not utilize the concept of gating mechanism.\nIn this paper, we proposed a new RNN architecture that combine the gating mechanism and tensor product concepts to incorporate both advantages in a single architecture. Using the concept of such gating mechanisms as LSTMRNN and GRURNN, our proposed architecture can learn temporal and sequential data with longer dependencies between each input time-step than simple RNNs without gating units and combine the gating units with tensor products to represent the hidden layer with more powerful operation and direct interaction. Hidden states are generated by the interaction between current input and previous (or future) hidden states using a tensor product and a non-linear activation function allows more expressive model representation. We describe two different models based on LSTMRNN and GRURNN.

The best way is to make sure that the toddler is very active during the day and is tired enough to fall asleep naturally. The toddler should get enough sunlight. Avoid or minimize exposure to digital screens such as television, tablet, and smartphones. Create a daily bedtime routine. For example, you can start the routine by feeding a bottle of milk, reading a story from a picture book, singing a lullaby, and shushing.

        "question": "Why the specific lottery image prior structure is superior to other structures in DIP tasks?",
        "answer": "Thanks for the advice. We add the experiments of studying the layer-wise sparsity ratio and the learning curves of different subnetworks, to add to the interpretability of what is special about LIP subnetworks. The results are summarized in Figure 11 and 13 in the section - Supplementary Materials of the paper. As shown in Figure 11, the structure of the LIP subnetwork is drastically different from those found by SNIP and random pruning, in particular the distribution of layerwise sparsity ratios. LIP tends to preserve weights of the earlier layers (closer to the input), while pruning the latter layers more aggressively (e.g, Figure 11(a).). In contrast, SNIP tends to prune much more of the earlier layers compared to the latter ones. Random pruning by default prunes each layer at approximately the same ratio. Comparing the three methods seems to suggest that for finding effective and transferable LIP subnetworks, specifically keeping more weights at earlier layers more is important. This is an explainable finding because, in image restoration tasks, the low-level features (color, texture, shape, etc.) presumably matter more and are more transferable,  than the high-level features (object categories, etc.). The earlier layers are known to capture more low-level image features, hence contributing more to retraining the image restoration performance with DIP. To better explain the success of the LIP subnetworks, inspired by the Figure 2 of the paper “Deep Image Prior”, we further train the obtained subnetworks (LIP, SNIP and random pruning) with four different targets: 1) a natural image, 2) the same added with noise, 3) the same after randomly permuting the pixels and 4) the white noise. We also train the dense model as the baseline. The experimental results are summarized in Figure 13. We first observe that for LIP, SNIP and dense models, the optimization converges much faster in case 1) and 2) than in case 3) and 4). But the randomly pruned subnetworks have failed in all cases. Interestingly, we also find that SNIP subnetworks perform similarly with the dense model. Meanwhile, the parametrization of LIP subnetworks offers a higher impedance to noise and a lower impedance to signal than the dense model, which indicates that the separation of high frequency and low frequency is more obvious for winning network architectures. ",
        "evidence": "Background Deep neural networks (DNNs), in particular convolutional neural networks (CNNs), have been powerful tools for solving various image inverse problems such as denoising, inpainting, and super resolution. Conventional wisdom believes that is owing to DNNs' universal approximation ability and learning from massive training data. Yet, recent studies have revealed the specific architectures of CNNs have the inductive bias to represent and generate natural images well, and such favorable architecture inductive bias can work independently from fitting specific training sets.\nFor example, deep image prior (DIP) shows an untrained neural network can be used as a handcrafted prior that transfers well across multiple inverse problems. The authors attributed the success to the CNN architecture itself, that appeared to possess high noise impedance even with only random initializations. As another example, in compressive sensing,; replaced the common structural assumptions such as sparsity with a pretrained generative adversarial networks. The underlying rationale lies in that a pre-trained generator should (approximately) represent the notion of a vector being or more likely in the target domain such as natural images; in other words, a sample more like a natural image will be closer to the output range of the pre-trained generator. In this paper, we refer to such general-purpose image prior parameterized by (either untrained or pre-trained) DNNs as DNN-based image priors.\nRecall that, classical image regularizers in the spatial or frequency domains are often not learningbased, or rely on compact learning models. On contrary, DNN-based image priors have a massive number of parameters (we compare the parameter numbers between the full model and the sparse subnetwork in Table 2), typically magnitudes more than the image (even the image size) size. The two extremes invite the natural question: Can we identify highly compact DNN-based image priors, that are same effective? We note that, diving into this question has twofold appeals. On the algorithmic side, that could help us understand further how the topology and connectivity of CNN architecture itself will affect the effectiveness of those priors, and to what extent sparsity could be relevant. On the practical side, if we could provide an affirmative answer to this question, that would potentially lead to more computationally savings when applying those DNN-based priors in practice, leading to faster restoration or computational imaging with them.\nTowards the above question, the tool we refer to in this paper is the recently emerged Lottery Ticket Hypothesis (LTH). LTH suggests that every dense DNN has an extremely sparse \"matching subnetwork\", that can be trained in isolation to match the original dense DNN's accuracy. While the vanilla LTH studies training from random scratch, the latest works also extend similar findings to fine-tuning the pre-trained models. LTH has widespread success in image classification, language modeling, reinforcement learning and multi-modal learning, e.g.,.\nOur Contributions Drawing inspirations from the LTH literature, we conjecture and empirically study a novel \"lottery image prior\" (LIP), stated as: Given an (untrained or trained) DNN-based image prior, it will have a sparse subnetwork that can be trained in isolation, to match the original DNN's performance when being applied as a prior to regularizing various image inverse problems.\nStudying this new problem is, however, NOT a naive extension from the existing LTH methods, owing to several technical barriers: (a) till now, LTH has not been demonstrated for image inverse problem or DNN-based priors, to our best knowledge. Most LTH works studied discriminative tasks, with one exception. It is therefore uncertain whether high-sparsity DNN is still viable for reconstruction-oriented tasks; (b) existing LTH works typically require a full training set to locate the sparse subnetwork mask, whereas our LIP settings are only not data-rich. For example, DIP needs the DNN to be trained to overfit one specific image, making it drastically different from previous problems; (c) the objectives between finding the sparse mask (e.g., learning the prior) and fitting the sparse subnetwork (e.g., using the prior) are often unaligned in LIP problems. For example, DIP will overfit a corrupted input image (during which the sparse mask will be found) in order to reconstruct a clean output image (when the found sparse subnetwork will be used); the pre-trained generator will also be used towards a different goal (regularizing compressive sensing) from their original pre-training task (generating realistic images).\nOur extensive experimental study confirms the existence of LIP in two representative settings: (i) image restoration with the deep image prior, using an untrained DNN (as shown in Fig.); and\n(ii) compressive sensing image reconstruction, using a pre-trained GAN generator. Using iterative magnitude pruning (IMP) with surrogate tasks (the overview of our work paradigm is in Fig.), we can successfully locate the LIP subnetworks at the sparsity range of 20%-86.58% in setting i; and those at the sparsity range of 5%-36% in setting ii. Those LIP subnetworks also possess high transferability. For example, the LIP ticket found in the setting i transfer well across not only different images, but also different tasks such as denoising, inpainting and super-resolution. Our contributions are summarized below:\n• The first comprehensive study on LTH in DNN-based image priors and inverse problems, establishing the \"lottery image prior\" (LIP) and demonstrating the prevailing relevance of LTH more broadly than previously typical settings. The last column (in blue) intends to display the results with the most extremely sparse subnetwork.\n• The investigation of both untrained and pre-trained DNNs as image priors, verifying that LIP subnetworks can be found in both settings, by overcoming several impediments such as severely limited training data and task objective mismatch. • High transferability of LIP subnetworks across data/datasets, and various inverse problem tasks. Our finding reflects the underlying common image prior that is agnostic to specific data or task, through the lens of the CNN architecture together with sparsity.\nFigure 11: Layer-wise sparsity ratio results of LIP, SNIP and randomly pruned tickets. Note that we summarize the sparsity ratio of each layer: the ratio of the number of parameters whose values are equal to zero to the number of total parameters of the layer. And the x-axis of these figures is composed of the serial numbers of model layers. We sampled subnetworks with four different sparsities (sparsity = 36%, 59%, 89%, 95%) to observe.****Figure 13: Learning curves using four different training targets: a clean image (Baby.png), the same image added with noises, the same randomly scrambled and white noise. Note that we use four different models: the LIP subnetwork (S = 89%), randomly pruned subnetwork (S = 89%), SNIP subnetwork (S = 89%) and the dense model (S = 0%). And we trained them in isolation in the same experimental settings for 10000 iterations.****Figure 2: LIP visual results: inpainting (row 1), super-resolution (rows 2/3) and denoising (row 4).

        "evidence": "Story-telling is on the frontier of current text generation technology: stories must remain thematically consistent across the complete document, requiring modeling very long range dependencies; stories require creativity; and stories need a high level plot, necessitating planning ahead rather than word-by-word generation BIBREF0 .\nWe tackle the challenges of story-telling with a hierarchical model, which first generates a sentence called the prompt describing the topic for the story, and then conditions on this prompt when generating the story. Conditioning on the prompt or premise makes it easier to generate consistent stories because they provide grounding for the overall plot. It also reduces the tendency of standard sequence models to drift off topic.\nWe find that standard sequence-to-sequence (seq2seq) models BIBREF1 applied to hierarchical story generation are prone to degenerating into language models that pay little attention to the writing prompt (a problem that has been noted in other domains, such as dialogue response generation BIBREF2 ). This failure is due to the complex and underspecified dependencies between the prompt and the story, which are much harder to model than the closer dependencies required for language modeling (for example, consider the subtle relationship between the first sentence and prompt in Figure FIGREF1 ).\nTo improve the relevance of the generated story to its prompt, we introduce a fusion mechanism BIBREF3 where our model is trained on top of an pre-trained seq2seq model. To improve over the pre-trained model, the second model must focus on the link between the prompt and the story. For the first time, we show that fusion mechanisms can help seq2seq models build dependencies between their input and output.\nAnother major challenge in story generation is the inefficiency of modeling long documents with standard recurrent architectures—stories contain 734 words on average in our dataset. We improve efficiency using a convolutional architecture, allowing whole stories to be encoded in parallel. Existing convolutional architectures only encode a bounded amount of context BIBREF4 , so we introduce a novel gated self-attention mechanism that allows the model to condition on its previous outputs at different time-scales.\nTo train our models, we gathered a large dataset of 303,358 human generated stories paired with writing prompts from an online forum. Evaluating free form text is challenging, so we also introduce new evaluation metrics which isolate different aspects of story generation.\nExperiments show that our fusion and self-attention mechanisms improve over existing techniques on both automated and human evaluation measures. Our new dataset and neural architectures allow for models which can creatively generate longer, more consistent and more fluent passages of text. Human judges prefer our hierarchical model's stories twice as often as those of a non-hierarchical baseline.\nExisting convolutional architectures only encode a bounded amount of context, so we introduce a novel gated self-attention mechanism that allows the model to condition on its previous outputs at different time-scales.",

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe use a Causal Diagram to analyze and remove the effects of the data bias (e.g., the speakers’ reputations, popularity gained by publicity, etc.) in our prediction model.",

        "evidence": "The ability to continuously learn and accumulate knowledge throughout a lifetime and reuse it effectively to adapt to a new problem quickly is a hallmark of general intelligence. State-of-the-art machine learning models work well on a single dataset given enough training examples, but they often fail to isolate and reuse previously acquired knowledge when the data distribution shifts (e.g., when presented with a new dataset)—a phenomenon known as catastrophic forgetting BIBREF0 , BIBREF1 .\nThe three main approaches to address catastrophic forgetting are based on: (i) augmenting the loss function that is being minimized during training with extra terms (e.g., a regularization term, an optimization constraint) to prevent model parameters learned on a new dataset from significantly deviating from parameters learned on previously seen datasets BIBREF2 , BIBREF3 , BIBREF4 , (ii) adding extra learning phases such as a knowledge distillation phase, an experience replay BIBREF5 , BIBREF6 , and (iii) augmenting the model with an episodic memory module BIBREF7 . Recent methods have shown that these approaches can be combined—e.g., by defining optimization constraints using samples from the episodic memory BIBREF8 , BIBREF9 .\nIn language learning, progress in unsupervised pretraining BIBREF10 , BIBREF11 , BIBREF12 has driven advances in many language understanding tasks BIBREF13 , BIBREF14 . However, these models have been shown to require a lot of in-domain training examples, rapidly overfit to particular datasets, and are prone to catastrophic forgetting BIBREF15 , making them unsuitable as a model of general linguistic intelligence.\nIn this paper, we investigate the role of episodic memory for learning a model of language in a lifelong setup. We propose to use such a component for sparse experience replay and local adaptation to allow the model to continually learn from examples drawn from different data distributions. In experience replay, we randomly select examples from memory to retrain on. Our model only performs experience replay very sparsely to consolidate newly acquired knowledge with existing knowledge in the memory into the model. We show that a 1% experience replay to learning new examples ratio is sufficient. Such a process bears some similarity to memory consolidation in human learning BIBREF16 . In local adaptation, we follow Memory-based Parameter Adaptation BIBREF7 and use examples retrieved from memory to update model parameters used to make a prediction of a particular test example.\nOur setup is different than a typical lifelong learning setup. We assume that the model only makes one pass over the training examples, similar to BIBREF9 . However, we also assume neither our training nor test examples have dataset identifying information (e.g., a dataset identity, a dataset descriptor). Our experiments focus on lifelong language learning on two tasks—text classification and question answering. BIBREF17 show that many language processing tasks (e.g., classification, summarization, natural language inference, etc.) can be formulated as a question answering problem. We argue that our lifelong language learning setup—where a model is presented with question-answer examples without an explicit identifier about which dataset (distribution) the examples come from—is a more realistic setup to learn a general linguistic intelligence model.\nOur main contributions in this paper are:\nIn this paper, we investigate the role of episodic memory for learning a model of language in a lifelong setup.",

In 1954, the Western Development Division, under General Bernard Schriever, was established as the first dedicated space organization within the U.S. Armed Forces and continues to exist as the Space Force's Space and Missile Systems Center. Military space forces were organized under several different Air Force major commands until they were unified when Air Force Space Command was established on 1 September 1982. U.S. space forces first began conducting combat support operations in the Vietnam War and continued to provide satellite communications, weather, and navigation support during the 1982 Falklands War, 1983 United States invasion of Grenada, 1986 United States bombing of Libya, and 1989 United States invasion of Panama. The first major employment of space forces culminated in the Gulf War, where they proved so critical to the U.S.-led coalition that it is sometimes referred to as the first \"space war\".\n\nThe first discussions of creating a military space service occurred in 1958, and it was nearly established in 1982 by President Ronald Reagan as part of the Strategic Defense Initiative, but the idea dissolved with treaty compliance concerns. A 2001 Space Commission argued for the creation of a Space Corps around 2007–2011, but no action was taken by the Obama Administration. On 20 December 2019, the United States Space Force Act was signed into law as part of the National Defense Authorization Act, reorganizing Air Force Space Command and other space elements into the United States Space Force, and creating the first new independent military service since the Army Air Forces were reorganized as the U.S. Air Force in 1947.",

These recordings were all by the acoustical process, as well as vertically-cut, through 1925, but he made his first electrical recordings in 1926 for Brunswick Records using that company's problematic \"Light-Ray\" system. After his unsatisfactory experience with Brunswick, Spalding went back to Edison and made some electrical Edison hill-and-dale Diamond Discs as well as a very few Edison \"Needle Cut\" lateral recordings in late 1928. These were much better recorded than Spalding's Brunswicks, but the Diamond Discs sold as scantily as the rest of Edison's product in that period, and the \"Needle-Cut\" discs were issued only for a very short time—from August to November 1929—and are exceedingly rare today.

At MAC, Metcalfe was responsible for building some of the hardware that would link MIT's minicomputers with ARPAnet. Metcalfe made ARPAnet the topic of his doctoral thesis, but Harvard initially rejected it. Metcalfe decided how to improve his thesis while working at Xerox PARC, where he read a paper about the ALOHA network at the University of Hawaii. He identified and fixed some of the bugs in the AlohaNet model, then added that work to his revised thesis. It was then accepted by Harvard, which granted his PhD.\n\nMetcalfe was working at PARC in 1973 when he and David Boggs invented Ethernet, initially as a standard for connecting computers over short distances. He later recalled that Ethernet was born on May 22, 1973, the day he circulated a memo titled \"Alto Ethernet\" which contained a rough schematic of how it would work. \"That is the first time Ethernet appears as a word, as does the idea of using coax as ether, where the participating stations, like in AlohaNet or ARPAnet, would inject their packets of data, they'd travel around at megabits per second, there would be collisions, and retransmissions, and back-off,\" Metcalfe explained. Boggs argued that another date was the birth of Ethernet: November 11, 1973, the first day the system actually functioned.\n\nIn 1979, Metcalfe departed PARC and co-founded 3Com, a manufacturer of computer networking equipment, in his Palo Alto apartment. 3Com became a leading provider of networking solutions, and Ethernet became the dominant networking standard for local area networks (LANs). In 1980 he received the ACM Grace Hopper Award for his contributions to the development of local networks, specifically Ethernet. In 1990, the 3Com board of directors appointed Éric Benhamou as CEO instead of Metcalfe, who then left the company. He spent 10 years as a publisher and pundit, writing an internet column for InfoWorld. In 1996, he co-founded Pop!Tech, an executive technology conference. He became a venture capitalist in 2001 and subsequently a general partner at Polaris Venture Partners.\n\nFrom 2011 to 2021 he was a professor at The University of Texas at Austin's Cockrell School of Engineering, specializing in innovation initiatives. Metcalfe was a keynote speaker at the 2016 Congress of Future Science and Technology Leaders and in 2019 he presented the Bernard Price Memorial Lecture in South Africa.

        "answer": "Bicycling is a form of human powered movement that typically involves sitting or standing on a machine with two wheels that can be propelled forward by using one's arms or legs.  The bicycle was invented in the early 1800 (1817) by a German inventor named Drais.  The early bicycles were built from wood and soon after used heavy steel for the frame and wheels.  These steel bikes were called Boneshakers because when you road on them you would feel every stone and bump through your bones.  Bicycling exists in nearly every corner of the world, on every continent and it is done by all people.  In many countries, bicycling is the primary mode of transportation for people, especially in urban settings.  Bicycling is also a professional sporting competition where men and women race against one another in large groups in front of cheering crowds.  Bicycling is a very efficient form of converting power generated by a human into forward motion.  While most humans can't run faster than 10 miles per hour for more than a few miles, humans can go much faster and often hundreds of miles when using a bicycle.  Because modern bicycles use pneumatic tires and have many gears, it is considered a very healthy form of exercise.

        "evidence": "Visual Question Answering (VQA) refers to a challenging task which lies at the intersection of image understanding and language processing. The VQA task has witnessed a significant progress in the recent years by the machine intelligence community. The aim of VQA is to develop a system to answer specific questions about an input image. The answer could be in any of the following forms: a word, a phrase, binary answer, multiple choice answer, or a fill in the blank answer. Agarwal et al. BIBREF0 presented a novel way of combining computer vision and natural language processing concepts of to achieve Visual Grounded Dialogue, a system mimicking the human understanding of the environment with the use of visual observation and language understanding.\nThe advancements in the field of deep learning have certainly helped to develop systems for the task of Image Question Answering. Krizhevsky et al BIBREF1 proposed the AlexNet model, which created a revolution in the computer vision domain. The paper introduced the concept of Convolution Neural Networks (CNN) to the mainstream computer vision application. Later many authors have worked on CNN, which has resulted in robust, deep learning models like VGGNet BIBREF2, Inception BIBREF3, ResNet BIBREF4, and etc. Similarly, the recent advancements in natural language processing area based on deep learning have improved the text understanding prforance as well. The first major algorithm in the context of text processing is considered to be the Recurrent Neural Networks (RNN) BIBREF5 which introduced the concept of prior context for time series based data. This architecture helped the growth of machine text understanding which gave new boundaries to machine translation, text classification and contextual understanding. Another major breakthrough in the domain was the introduction of Long-Short Term Memory (LSTM) architecture BIBREF6 which improvised over the RNN by introducing a context cell which stores the prior relevant information.\nThe vanilla VQA model BIBREF0 used a combination of VGGNet BIBREF2 and LSTM BIBREF6. This model has been revised over the years, employing newer architectures and mathematical formulations. Along with this, many authors have worked on producing datasets for eliminating bias, strengthening the performance of the model by robust question-answer pairs which try to cover the various types of questions, testing the visual and language understanding of the system. In this survey, first we cover major datasets published for validating the Visual Question Answering task, such as VQA dataset BIBREF0, DAQUAR BIBREF7, Visual7W BIBREF8 and most recent datasets up to 2019 include Tally-QA BIBREF9 and KVQA BIBREF10. Next, we discuss the state-of-the-art architectures designed for the task of Visual Question Answering such as Vanilla VQA BIBREF0, Stacked Attention Networks BIBREF11 and Pythia v1.0 BIBREF12. Next we present some of our computed results over the three architectures: vanilla VQA model BIBREF0, Stacked Attention Network (SAN) BIBREF11 and Teney et al. model BIBREF13. Finally, we discuss the observations and future directions.\nVisual Question Answering (VQA) refers to a challenging task which lies at the intersection of image understanding and language processing. The VQA task has witnessed a significant progress the recent years by the machine intelligence community. The aim of VQA is to develop a system to answer specific questions about an input image.",

        "question": "Can I make chocolate at home?",
        "evidence": "",
        "answer": "Making chocolate at home can be rewarding, but be prepared to spend a little money and a lot of time. The money goes to equipment and cocoa beans. For equipment, you will need a melanger (about $600)  to grind the beans and a tempering machine (about $400) to make the finished product. You will also need a silicone mat (about $20) and a hair dryer (about $30). But let's start at the beginning.\n\nBuy between two and six pounds of fermented raw cocoa beans. There are a variety of retail importers you can find on the web. Choose a single variety or a blend that appeals to your taste in chocolate.\n\nSort the beans, removing broken beans, badly misshapen beans, and whatever foreign bodies may be present.\n\nRoast the beans, two pounds at a time, at 350F for between 20 and 30 minutes, depending on your experience with the beans or by how they smell. They will smell like fresh brownies. Don't scorch them!\n\nLet the beans cool.\n\nPeel the beans. You can do this by hand - which I find produces a superior product - but be warned that this can take up to 6 hours per pound. Alternatively, you can purchase a winnower and use the hair dryer to blow out the skins. This approach is much faster, but leaves more skin and loses more bean fragments. Either way, weigh your final bean yield.\n\nGet you melanger going. Use the hair dryer to get the grinding surfaces up to at least 120F. Add the beans a handful at a time. Help the melanger along if it gets stuck. Make sure the melanger is going steadily before leaving it unattended. When it gets going, it will flow well.\n\nRun the melanger for 24 to 72 hours, again depending on your experience with the beans and your tastes. If trying a mix of beans, add the more robustly flavored beans early in the process and the more delicately flavored beans later. Give even the most delicate beans at least 8 hours. Add sugar to taste. The percentage of sugar by weight can vary from a few percent up to 30 percent. You may also add dried whole fat milk at this point, and other flavorings, like an inch or so of vanilla bean. Melange the sugar and other additives at least 8 more hours. The goal is to decrease the particle size below what can be detected by the  tongue. When done, decant into a silicone mat line baking pan. This is your untempered chocolate. it melts easily and tends to get crumbly as it ages. Which is why you will want to temper it.\n\nFinally, follow the directions on your tempering machine, adding chunks of untempered chocolate as indicated. The liquid tempered chocolate can be used for fruit dipping or can be poured into molds for bars or shaped candies. Other additives can be included at this stage - nuts, nougat etc. Cool the results at room temperature for several hours before serving. Enjoy the results of your labor.",

        "question": "What are the initial strong baselines which represent two complementary directions of research?",
        "answer": "One based on the aggregation of multilingual word embeddings, and another one, which directly learns multilingual sentence representations.",
        "evidence": "In this section, we provide comparative results on our new Multilingual Document Classification Corpus. Since the initial work by BIBREF0 many alternative approaches to cross-lingual document classification have been developed. We will encourage the respective authors to evaluate their systems on MLDoc. We believe that a large variety of transfer language pairs will give valuable insights on the performance of the various approaches.\nIn this paper, we propose initial strong baselines which represent two complementary directions of research: one based on the aggregation of multilingual word embeddings, and another one, which directly learns multilingual sentence representations. Details on each approach are given in section \"Multilingual word representations\" and \"Multilingual sentence representations\" respectively. In contrast to previous works on cross-lingual document classification with RVC2, we explore training the classifier on all languages and transfer it to all others, ie. we do not limit our study to the transfer between English and a foreign language.\nOne can envision several ways to define cross-lingual document classification, in function of the resources which are used in the source and transfer language (see Table 3 ). The first scheme assumes that we have no resources in the transfer language at all, neither labeled nor unlabeled. We will name this case “zero-shot cross-lingual document classification”. To simplify the presentation, we will assume that we transfer from English to German. The training and evaluation protocol is as follows. First, train a classifier using resources in the source language only, eg. the training and development corpus are in English. All meta parameters and model choices are performed using the English development corpus. Once the best performing model is selected, it is applied to the transfer language, eg. the German test set. Since no resources of the transfer language are used, the same system can be applied to many different transfer languages. This type of cross-lingual document classification needs a very strong multilingual representation since no knowledge on the target language was used during the development of the classifier.\nIn a second class of cross-lingual document classification, we may aim in improving the transfer performance by using a limited amount of resources in the target language. In the framework of the proposed MLDoc we will use the development corpus of target language for model selection. We will name this method “targeted cross-lingual document classification” since the system is tailored to one particular transfer language. It is unlikely that this system will perform well on other languages than the ones used for training or model selection.\nIf the goal is to build one document classification system for many languages, it may be interesting to use already several languages during training and model selection. To allow a fair comparison, we will assume that these multilingual resources have the same size than the ones used for zero-shot or targeted cross-language document classification, e.g. a training set composed of five languages with 200 examples each. This type of training is not a cross-lingual approach any more. Consequently, we will refer to this method as “joint multilingual document classification”.\nIn this paper, we propose initial strong baselines which represent two complementary directions of research: one based on the aggregation of multilingual word embeddings, and another one, which directly learns multilingual sentence representations.",

In addition, they intend to generalize the output received in the current experiment, with evaluation over other datasets, including analyzing texts written in different languages.",
        "evidence": "In this work we present an ensemble classifier that is detecting hate-speech in short text, such as tweets. The input to the base-classifiers consists of not only the standard word uni-grams, but also a set of features describing each user's historical tendency to post abusive messages. Our main innovations are: i) a deep learning architecture that uses word frequency vectorisation for implementing the above features, ii) an experimental evaluation of the above model on a public dataset of labeled tweets, iii) an open-sourced implementation built on top of Keras.\nThe results show that our approach outperforms the current state of the art, and to the best of our knowledge, no other model has achieved better performance in classifying short messages. The approach does not rely on pre-trained vectors, which provides a serious advantage when dealing with short messages of this kind. More specifically, users will often prefer to obfuscate their offensive terms using shorter slang words or create new words by `inventive' spelling and word concatenation. For instance, the word `Islamolunatic' is not available in the popular pre-trained word embeddings (Word2Vec or GloVe), even though it appears with a rather high frequency in racist postings. Hence, word frequency vectorization is preferable to the pre-trained word embeddings used in prior works if one aims to build a language-agnostic solution.\nWe believe that deep learning models have a high potential wrt. classifying text or analyzing the sentiment in general. In our opinion there is still space for further improving the classification algorithms.\nFor future work we plan to investigate other sources of information that can be utilized to detect hateful messages. In addition, we intend to generalize the output received in the current experiment, with evaluation over other datasets, including analyzing texts written in different languages.\nFor future work we plan to investigate other sources of information that can be utilized to detect hateful messages.

This raised philosophical arguments about the mind and the ethical consequences of creating artificial beings endowed with human-like intelligence; these issues have previously been explored by myth, fiction, and philosophy since antiquity.

In 1976, Doris Morgan, a first year post-doctoral fellow in Gallo's lab, was asked by Gallo to examine culture fluid of activated lymphocytes for the possible production of growth factors. Soon she was successful in growing T lymphocytes. Gallo, Morgan and Frank Ruscetti, another researcher in Gallo's lab, coauthored a paper in Science describing their method. The Gallo group identified this as T-cell growth factor (TCGF). The name was changed in 1978 to IL-2 (interleukin-2) by the Second International Lymphokine Conference (which was held in Interlaken, Switzerland). Although earlier reports had described soluble molecules with biologic effects, the effects and biochemistry of the factors were not well characterized. One such example was the report by Julius Gordon in 1965, which described blastogenic transformation of lymphocytes in extracellular media. However, cell growth was not demonstrated and the affected cell type was not identified, making the identity of the factor(s) involved unclear and its natural function unknown.\nThe discovery of IL-2 allowed T cells, previously thought to be dead end cells, to be grown significantly in culture for the first time, opening research into many aspects of T cell immunology. Gallo's lab later purified and biochemically characterized IL-2. This breakthrough also allowed researchers to grow T-cells and study the viruses that affect them, such as human T-cell leukemia virus, or HTLV, the first retrovirus identified in humans, which Bernard Poiesz, another post-doctoral fellow in Gallo's lab played a key role in its isolation. HTLV's role in leukemia was clarified when Kiyoshi Takatsuki and other Japanese researchers, puzzling over an outbreak of a rare form of leukemia, later independently found the same retrovirus, and both groups showed HTLV to be the cause. At the same time, a similar HTLV-associated leukemia was identified by the Gallo group in the Caribbean.

        "evidence": "Medical providers across the United States are required to document clinical visits in the Electronic Health Records. This need for documentation takes up a disproportionate amount of their time and attention, resulting in provider burnout BIBREF0, BIBREF1. One study found that full-time primary care physicians spent about 4.5 hours of an 11-hour workday interacting with the clinical documentation systems, yet were still unable to finish their documentation and had to spend an additional 1.4 hours after normal clinical hours BIBREF2.\nSpeech and natural language processing are now sufficiently mature that there is considerable interest, both in academia and industry, to investigate how these technologies can be exploited to simplify the task of documentation, and to allow providers to dedicate more time to patients. While domain-specific automatic speech recognition (ASR) systems that allow providers to dictate notes have been around for a while, recent work has begun to address the challenges associated with generating clinical notes directly from speech recordings. This includes inducing topic structure from conversation data, extracting relevant information, and clinical summary generation BIBREF3. In one recent work, authors outlined an end-to-end system; however, the details were scant without empirical evaluations of their building blocks BIBREF4. One of the simplistic approaches uses a hand crafted finite state machine based grammar to locate clinical entities in the ASR transcripts and map them to canonical clinical terms BIBREF5. This seems to perform well in a narrowly scoped task. A more ambitious approach mapped ASR transcripts to clinical notes by adopting a machine translation approach BIBREF6. However this performed poorly. To address the difficulty in accessing clinical data, researchers have experimented with synthetic data to develop a system for documenting nurse-initiated telephone conversations for congestive heart failure patients who are undergoing telemonitoring after they have been discharged from the hospital BIBREF7. In their task, a question-answer based model achieved an F-score of 0.80. This naturally raises the question of how well state-of-art techniques will perform in helping the broader population of clinicians such as primary care providers.\nOne might expect that the task of extracting clinical concepts from audio faces challenges similar to the domain of unstructured clinical texts. In that domain, one of the earliest public-domain tasks is the i2b2 relations challenge, defined on a small corpus of written discharge summaries consisting of 394 reports for training, 477 for test, and 877 for evaluation BIBREF8. Given the small amount of training data, not surprisingly, a disproportionately large number of teams fielded rule-based systems. Conditional random field-based (CRF) systems BIBREF9 however did better even with the limited amount of training data BIBREF10. Other i2b2/n2c2 challenges focused on coreference resolution BIBREF11, temporal relation extraction BIBREF12, drug event extraction BIBREF13 on medical records, and extracting family history BIBREF14. Even though the text was largely unstructured, they benefited from punctuation and capitalization, section headings and other cues in written domain which are unavailable in audio to the same extent.\nWith the goal of creating an automated medical scribe, we broke down the task into modular components, including ASR and speaker diarization which are described elsewhere BIBREF15. In this work, we investigate the task of extracting relevant clinical concepts from transcripts. Our key contributions include: (i) defining three tasks – the Medications Task, the Symptoms Task, and the Conditions Task along with principles employed in developing the annotation guidelines for them (Section SECREF2); (ii) measuring the label quality using inter-labeler agreements and refining the quality iteratively (Section SECREF3), (iii) evaluating the performance of the state-of-the-art models on these tasks (Section SECREF4), and (iv) a comprehensive analysis of the performance of the models including manual error categorization (Section SECREF5).

        "answer": "Language space mismatch problem, also named domain shift problem brings about the failure.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem (Fu et al. 2015), brings about the zero-shot translation failure in transfer learning.",

To collect a diverse training dataset, we have randomly sampled 1000 posts each from the subreddits politics, business, science, and AskReddit, and 1000 additional posts from the Reddit frontpage. All posts in our sample appeared between January 2007 and March 2015, and to control for length effects, contain between 300 and 400 characters. This results in a total training dataset of 5000 posts.\nDogmatism annotations. Building a useful computational model requires labeled training data. We labeled the Reddit dataset using crowdworkers on Amazon Mechanical Turk (AMT), creating the first public corpus annotated with levels of dogmatism. We asked crowdworkers to rate levels of dogmatism on a 5-point Likert scale, as supported by similar annotation tasks in prior work BIBREF2 . Concretely, we gave crowdworkers the following task: \nGiven a comment, imagine you hold a well-informed, different opinion from the commenter in question. We'd like you to tell us how likely that commenter would be to engage you in a constructive conversation about your disagreement, where you each are able to explore the other's beliefs. The options are:\n(5): It's unlikely you'll be able to engage in any substantive conversation. When you respectfully express your disagreement, they are likely to ignore you or insult you or otherwise lower the level of discourse.\n(4): They are deeply rooted in their opinion, but you are able to exchange your views without the conversation degenerating too much.\n(3): It's not likely you'll be able to change their mind, but you're easily able to talk and understand each other's point of view.\n(2): They may have a clear opinion about the subject, but would likely be open to discussing alternative viewpoints.\n(1): They are not set in their opinion, and it's possible you might change their mind. If the comment does not convey an opinion of any kind, you may also select this option.\nTo ensure quality work, we restricted the task to Masters workers and provided examples corresponding to each point on the scale. Including examples in a task has been shown to significantly increase the agreement and quality of crowdwork BIBREF3 . For instance, here is an example of a highly dogmatic (5) comment: \nI won't be happy until I see the executive suite of BofA, Wells, and all the others, frog-marched into waiting squad cars. It's ALREADY BEEN ESTABLISHED that...\nAnd a minimally dogmatic (1) comment: \nI agree. I would like to compile a playlist for us trance yogi's, even if you just would like to experiment with it. Is there any preference on which platform to use?\nEach comment has been annotated by three independent workers on AMT, which is enough to produce reliable results in most labeling tasks BIBREF4 . To compute an aggregate measure of dogmatism for each comment, we summed the scores of all three workers. We show the resulting distribution of annotations in Figure 1 .\nInter-annotator agreement. To evaluate the reliability of annotations we compute Krippendorff's $\\alpha $ , a measure of agreement designed for variable levels of measurement such as a Likert scale BIBREF5 . An $\\alpha $ of 0 indicates agreement indistinguishable from chance, while an $\\alpha $ of 1 indicates perfect agreement. Across all annotations we find $\\alpha =0.44$ . While workers agree much more than chance, clearly dogmatism is also subjective. In fact, when we examine only the middle two quartiles of the dogmatism annotations, we find agreement is no better than chance. Alternatively, when we measure agreement only among the top and bottom quartiles of annotations, we find agreement of $\\alpha =0.69$ . This suggests comments with scores that are only slightly dogmatic are unreliable and often subject to human disagreement. For this reason, we use only the top and bottom quartiles of comments when training our model.\nInter-annotator agreement.

        "question": "Are the 4 BAE attack modes almost always stronger than previous baselines on 7 text classification datasets?",
        "answer": "Yes, they are.",
        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.",

        "question": "Does the RL model create responses that are potentially better at mitigating hate speech and are more diverse?",
        "answer": "Yes, it does.",
        "evidence": "The experimental results of the detection task and the generative intervention task are shown in Table TABREF27 and Table TABREF29 separately. The results of the human evaluation are shown in Table TABREF30. Figure FIGREF25 shows examples of the generated responses.\nAs shown in Table TABREF27 and TABREF29, all the classification and generative models perform better on the Gab dataset than on the Reddit dataset. We think this stems from the datasets' characteristics. First, the Gab dataset is larger and has a more balanced category distribution than the Reddit dataset. Therefore, it is inherently more challenging to train a classifier on the Reddit dataset. Further, the average lengths of the Reddit posts and conversations are much larger than those of Gab, potentially making the Reddit input nosier than the Gab input for both tasks. On both the Gab and Reddit datasets, the SVM classifier and the LR classifier achieved better performance than the CNN and RNN model with randomly initialized word embeddings. A possible reason is that without pretrained word embeddings, the neural network models tend to overfit on the dataset.\nFor the generative intervention task, three models perform similarly on all three automatic evaluation metrics. As expected, the Seq2Seq model achieves higher scores with filtered conversation as input. However, this is not the case for the VAE model. This indicates that the two models may have different capabilities to capture important information in conversations.\nAs shown in Table TABREF29, applying Reinforcement Learning does not lead to higher scores on the three automatic metrics. However, human evaluation (Table TABREF30) shows that the RL model creates responses that are potentially better at mitigating hate speech and are more diverse, which is consistent with BIBREF21. There is a larger performance difference with the Gab dataset, while the effectiveness and the diversity of the responses generated by the Seq2Seq model and the RL model are quite similar on the Reddit dataset. One possible reason is that the size of the training data from Reddit (around 8k) is only 30% the size of the training data from Gab. The inconsistency between the human evaluation results and the automatic ones indicates the automatic evaluation metrics listed in Table TABREF29 can hardly reflect the quality of the generated responses. As mentioned in Section SECREF4, annotators tend to have strategies for intervention. Therefore, generating the common parts of the most popular strategies for all the testing input can lead to high scores of these automatic evaluation metrics. For example, generating “Please do not use derogatory language.” for all the testing Gab data can achieve 4.2 on BLEU, 20.4 on ROUGE, and 18.2 on METEOR. However, this response is not considered as high-quality because it is almost a universal response to all the hate speech, regardless of the context and topic.\nSurprisingly, the responses generated by the VAE model have much worse diversity than the other two methods according to human evaluation. As indicated in Figure FIGREF25, the responses generated by VAE tend to repeat the responses related to some popular hate keyword. For example, “Use of the r-word is unacceptable in our discourse as it demeans and insults people with mental disabilities.” and “Please do not use derogatory language for intellectual disabilities.” are the generated responses for a large part of the Gab testing data. According to Figure FIGREF20, insults towards disabilities are the largest portion in the dataset, so we suspect that the performance of the VAE model is affected by the imbalanced keyword distribution.\nThe sampled results in Figure FIGREF25 show that the Seq2Seq and the RL model can generate reasonable responses for intervention. However, as is to be expected with machine-generated text, in the other human evaluation we conducted, where Mechanical Turk workers were also presented with sampled human-written responses alongside the machine generated responses, the human-written responses were chosen as the most effective and diverse option a majority of the time (70% or more) for both datasets. This indicates that there is significant room for improvement while generating automated intervention responses.\nIn our experiments, we only utilized the text of the posts, but more information is available and can be utilized, such as the user information and the title of a Reddit submission.\nHowever, human evaluation (Table 4) shows that the RL model creates responses that are potentially better at mitigating hate speech and are more diverse, which is consistent with Li et al.

        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nDuong et al. (2016) and Anastasopoulos et al.

For Tent with Adam optimizer, we use default hyperparameters of mini-batch size 128 and learning rate 0.001 in (Wang et al., 2021), but we still observe performance degradation in Camelyon17, iWildCam and VisDA in Table 3. Although the rate of adaptation can be reduced by decreasing learning rate, it is difficult to reliably select hyperparameters without labelled samples, and this is a challenge of using test-time adaptation methods in practice.",
        "evidence": "We compare our method with the baseline source models, as well as with test-time adaptation methods that also augment only batch normalization layers namely Test-time BN and the state-of-the-art Tent) that adapts BN parameters by entropy minimization with default hyperparameters i.e. Adam or SGD with momentum with mini-batch size 128 and learning rate 0.001. We point out that test-time adaptation methods are not designed for the same setting and are not directly comparable with our proposed method. We include them to show empirically that adapting with a few labelled samples can achieve better and more reliable classification performance than adapting with a large streaming dataset. On all datasets, we set mini-batch size as 32, and use Adam optimizer with 0.001 learning rate for finetuning LCCS. For larger support sets at k ≥ 5, we use the nearest-centroid-classifier as in instead of source classifier. We set n = k × # classes for µ LCCS for Camelyon17 and VisDA, and n = 1 otherwise.\nFrom Table, our proposed method improves over source models even with a single example per class for all datasets evaluated, and overall is comparable to or better than Test-time BN and Tent when k ≥ 5. We observe that Tent performance is dependent on optimizer choice, with Adam outperforming SGD by approximately 2% in PACS and SGD outperforming Adam by as much as 39.2% on VisDA. Since the better performing optimizer is dataset-dependent, this makes the practical usage of Tent challenging. For PACS, our proposed method performs better than the best case of Tent when support set has 5 or 10 samples per class. For Camelyon17, all BN adaptation methods improve over source model accuracy by at least 18% in the best scenario, implying that replacing source BN statistics with target BN statistics is effective in addressing domain shift in this dataset. For the 182-class iWildCam dataset, the test dataset is imbalanced; 102 classes have at least 1 sample, and only 87 classes have at least 5 samples. Hence to prevent introducing more class imbalance in the adaptation and evaluation processes, we only evaluate the setting where k = 1, which translates to 102 support samples. Our proposed method improves slightly over source model, while all test-adaptation methods obtained lower F1-score than the original baseline performance.\nSimilarly for VisDA, our proposed method obtains the best target performance. In particular, all test-time adaptation methods result in worse performance than original source model. We provide standard errors of results in Table in Appendix Section C.2.\nEffect of test batches: Although test-time adaptation methods can improve the source model without supervision of labelled samples, their performance relies on streaming conditions and severely degrades with smaller mini-batch size and class-imbalanced mini-batches as shown in Table, and in detail in Appendix Section C.2. We constructed long-tailed imbalanced PACS and VisDA following the procedure in, where sample sizes decay exponentially from the first to last class and α is the ratio of the largest to smallest class. The good performance of test-time methods is  dependent on having large, evenly classes-distributed mini-batches. On the contrary, our proposed method is not dependent on streaming conditions and can more reliably adapt to the target domain.\nAs far as we know, there are no existing methods designed and evaluated specifically for our sourcefree few-shot DA setting. We apply existing methods in DA and few-shot transfer learning to provide benchmark performance. We compare with AdaBN by replacing source BN statistics with those calculated on target support set, finetuning the source model on BN layers or classifier or feature extractor, finetuning entire model with L 2 or L 2 -SP or DELTA regularization, Late Fusion which averages scores from source and target classifier, and FLUTE which optimizes BN parameters with nearest-centroid classifier. FLUTE assumes the availability of multiple source datasets to train multiple sets of BN parameters for further blending to initialize the finetuning process. Since we only have access to the pre-trained source model in our setting, we reduce FLUTE to the single source dataset case and initialize FLUTE with single source BN parameters. It is conventional to update the classifier when sufficient target samples are available, hence besides implementing with source classifier (SC), we also implement our proposed method with finetuned classifier (FC) and nearestcentroid classifier (NCC). We follow learning settings in for regularized finetuning and use SGD optimizer with momentum and weight decay 0.0004, and L 2 regularization is also added to finetuning on classifier or feature extractor to prevent overfitting. For all other methods that finetune on BN layers, we use Adam optimizer following. We set learning rate 0.001, mini-batch size 32 and epochs 10 for all methods and datasets evaluated.\nFrom Table, we observe that regularized finetuning tends to adapt well at k = 1, but performance can lag behind with larger support sets. AdaBN does not consistently improve adaptation; we show in Appendix Figure that completely replacing source BN statistics degrades performance for VisDA. Overall, finetuning LCCS with source classifier has at least comparable performance with regularized finetuning for small support sets. For larger support sets, finetuning LCCS with NCC has the best performance, with classification accuracy consistently higher than FLUTE which also uses NCC. We also compare our method to L 2 and FLUTE on Office and OfficeHome in Table 16. Though the transfer learning methods produce comparable performance on the easy dataset of Camelyon17 (two classes, two domains), LCCS outperforms on more difficult datasets, which demonstrates the effectiveness of the proposed low-dimensional finetuning strategy.\nLCCS Finetuning vs BN Finetuning: We further study our proposed constrained optimization of BN layer versus the unconstrained alternative of optimizing directly on the high-dimensional BN parameters γ and β in Equation 1, with fixed source classifier. We also evaluate a combination of the two strategies by first finetuning LCCS followed by finetuning BN parameters. From Figure, we see that when the support set is small at k ≤ 3, finetuning LCCS is always better than finetuning BN parameters. The results are mixed at larger k, which is expected since the unconstrained optimization is also less prone to overfit with more samples. In addition, we observe that finetuning LCCS first provides good initialization for further finetuning of BN parameters, and consistently achieves better adaptation performance than finetuning BN parameters alone. We make similar observations when using NCC as classifier in Appendix Section C.5.  Figure: Finetuning LCCS has best performance when support set is extremely small (k ≤ 3).\nWith larger support set (k ≥ 5), finetuning LCCS+BN parameters attains better performance than finetuning BN parameters alone.\nWe compare our method with the baseline source models, as well as with test-time adaptation methods that also augment only batch normalization layers namely Test-time BN (Nado et al., 2020) and the state-of-the-art Tent (Wang et al., 2021a) that adapts BN parameters by entropy minimization with default hyperparameters i.e. Adam or SGD with momentum with mini-batch size 128 and learning rate 0.001.

On all datasets, we set mini-batch size as 32, and use Adam optimizer with 0.001 learning rate for finetuning LCCS. For larger support sets at k ≥ 5, we use the nearest-centroid-classifier as in (Triantafillou et al., 2021) instead of source classifier.

The output of KBMRC is a subject or an argument, while the output in MRC is a text span of the document. Meanwhile, KBMRC facilitates the accessing and leveraging of knowledge from external KBs because the document KB is consistent with the representation of facts in external KBs.\nKBMRC also relates to knowledge-base question answering (KBQA) BIBREF23 , which aims to answer questions based on an external large-scale KB such as Freebase or ProBase.

Moreover, existing benchmark datasets for KBQA such as WebQuestions BIBREF24 are typically limited to simple questions.

Ranking based approaches BIBREF17 , BIBREF25 are bottom-up, which typically first find a set of candidate answers and then rank between the candidates with features at different levels to get the answer. Parsing-based approaches BIBREF16 are top-down, which first interpret logical form from a natural language utterance, and then do execution to yield the answer. Ranking-based approaches achieve better performances than parsing-based approaches on WebQuestions, a benchmark dataset for KBQA. We follow ranking-based approaches, and develop both a matching-based model with features at different levels and a question generation model.

In this way, in combination with the original Recurrent Entity Network (keys and memory), we improved the State-of-The-Art in the bAbI 1k task and achieved promising results in the Reading comprehension task on the CNN & Daily news dataset. However, we believe that there are still margins for improving the behavior for the proposed cell. Indeed, the cell has not enough expressive power to make a selective activation among different memory blocks (notice in Figure 2 (a) the gates open for all the memories). This does not seem to be a serious problem since we actually outperform other models, but it could be the key to finally pass all the bAbI tasks.\nDynamic Memory stores information of entities present in $T$ . This module is very similar to a Gated Recurrent Unit (GRU) BIBREF20 with a hidden state divided into blocks. Moreover, each block ideally represents an entity (i.e. person, location etc.), and it stores relevant facts about it.

Additionally, only one model needs to be trained, rather than two distinct networks.",
        "evidence": "The basic idea in binary paragraph vector models is to introduce a sigmoid nonlinearity before the softmax that models the conditional probability of words given the context. If we then enforce binary or near-binary activations in this nonlinearity, the probability distribution over words will be conditioned on a bit vector context, rather than real-valued representation. The inference in the model proceeds like in Paragraph Vector, except the document code is constructed from the sigmoid activations. After rounding, this code can be seen as a distributed binary representation of the document.\nIn the simplest Binary PV-DBOW model (Figure FIGREF1 ) the dimensionality of the real-valued document embeddings is equal to the length of the binary codes. Despite this low dimensional representation – a useful binary hash will typically have 128 or fewer bits – this model performed surprisingly well in our experiments.\nNote that we cannot simply increase the embedding dimensionality in Binary PV-DBOW in order to learn better codes: binary vectors learned in this way would be too long to be useful in document hashing. The retrieval performance can, however, be improved by using binary codes for initial filtering of documents, and then using a representation with higher capacity to rank the remaining documents by their similarity to the query. BIBREF3 , for example, used semantic hashing codes for initial filtering and TF-IDF for ranking. A similar document retrieval strategy can be realized with binary paragraph vectors. Furthermore, we can extend the Binary PV-DBOW model to simultaneously learn short binary codes and higher-dimensional real-valued representations. Specifically, in the Real-Binary PV-DBOW model (Figure FIGREF2 ) we introduce a linear projection between the document embedding matrix and the sigmoid nonlinearity. During training, we learn the softmax parameters and the projection matrix. During inference, softmax weights and the projection matrix are fixed. This way, we simultaneously obtain a high-capacity representation of a document in the embedding matrix, e.g. 300-dimensional real-valued vector, and a short binary representation from the sigmoid activations.\nOne advantage of using the Real-Binary PV-DBOW model over two separate networks is that we need to store only one set of softmax parameters (and a small projection matrix) in the memory, instead of two large weight matrices. Additionally, only one model needs to be trained, rather than two distinct networks.\nBinary document codes can also be learned by extending distributed memory models. BIBREF7 suggest that in PV-DM, a context of the central word can be constructed by either concatenating or averaging the document vector and the embeddings of the surrounding words. However, in Binary PV-DM (Figure FIGREF3 ) we always construct the context by concatenating the relevant vectors before applying the sigmoid nonlinearity. This way, the length of binary codes is not tied to the dimensionality of word embeddings.\nSoftmax layers in the models described above should be trained to predict words in documents given binary context vectors. Training should therefore encourage binary activations in the preceding sigmoid layers. This can be done in several ways. In semantic hashing autoencoders BIBREF3 added noise to the sigmoid coding layer. Error backpropagation then countered the noise, by forcing the activations to be close to 0 or 1. Another approach was used by BIBREF12 in autoencoders that learned binary codes for small images. During the forward pass, activations in the coding layer were rounded to 0 or 1. Original (i.e. not rounded) activations were used when backpropagating errors. Alternatively, one could model the document codes with stochastic binary neurons. Learning in this case can still proceed with error backpropagation, provided that a suitable gradient estimator is used alongside stochastic activations. We experimented with the methods used in semantic hashing and Krizhevsky's autoencoders, as well as with the two biased gradient estimators for stochastic binary neurons discussed by BIBREF13 . We also investigated the slope annealing trick BIBREF14 when training networks with stochastic binary activations. From our experience, binary paragraph vector models with rounded activations are easy to train and learn better codes than models with noise-based binarization or stochastic neurons. We therefore use Krizhevsky's binarization in our models.\nOne advantage of using the Real-Binary PV-DBOW model over two separate networks is that we need to store only one set of softmax parameters (and a small projection matrix) in the memory, instead of two large weight matrices.

        "answer": "Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc.",
        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nHate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc.",

        "evidence": "After World War II, parts of Eastern and Central Europe, including East Germany and eastern parts of Austria were occupied by Red Army according to the Potsdam Conference. Dependent communist governments were installed in the Eastern Bloc satellite states. After becoming the world's second nuclear power, the Soviet Union established the Warsaw Pact alliance, and entered into a struggle for global dominance, known as the Cold War, with the rivaling United States and NATO. After Stalin's death in 1953 and a short period of collective rule, the new leader Nikita Khrushchev denounced Stalin and launched the policy of de-Stalinization, releasing many political prisoners from the Gulag labor camps. The general easement of repressive policies became known later as the Khrushchev Thaw. At the same time, Cold War tensions reached its peak when the two rivals clashed over the deployment of the United States Jupiter missiles in Turkey and Soviet missiles in Cuba.\n\nIn 1957, the Soviet Union launched the world's first artificial satellite, Sputnik 1, thus starting the Space Age. Russian cosmonaut Yuri Gagarin became the first human to orbit the Earth, aboard the Vostok 1 manned spacecraft on 12 April 1961. Following the ousting of Khrushchev in 1964, another period of collective rule ensued, until Leonid Brezhnev became the leader. The era of the 1970s and the early 1980s was later designated as the Era of Stagnation. The 1965 Kosygin reform aimed for partial decentralisation of the Soviet economy. In 1979, after a communist-led revolution in Afghanistan, Soviet forces invaded the country, ultimately starting the Soviet–Afghan War. In May 1988, the Soviets started to withdraw from Afghanistan, due to international opposition, persistent anti-Soviet guerrilla warfare, and a lack of support by Soviet citizens.\n\nFrom 1985 onwards, the last Soviet leader Mikhail Gorbachev, who sought to enact liberal reforms in the Soviet system, introduced the policies of glasnost (openness) and perestroika (restructuring) in an attempt to end the period of economic stagnation and to democratise the government. This, however, led to the rise of strong nationalist and separatist movements across the country. Prior to 1991, the Soviet economy was the world's second-largest, but during its final years, it went into a crisis.\n\nBy 1991, economic and political turmoil began to boil over as the Baltic states chose to secede from the Soviet Union. On 17 March, a referendum was held, in which the vast majority of participating citizens voted in favour of changing the Soviet Union into a renewed federation. In June 1991, Boris Yeltsin became the first directly elected president in Russian history when he was elected president of the Russian SFSR. In August 1991, a coup d'état attempt by members of Gorbachev's government, directed against Gorbachev and aimed at preserving the Soviet Union, instead led to the end of the Communist Party of the Soviet Union. On 25 December 1991, following the dissolution of the Soviet Union, along with contemporary Russia, fourteen other post-Soviet states emerged.",

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\nMoreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.",

        "evidence": "The present work: Binomials in large-scale online text. In this work, we use data from large-scale Internet text corpora to study binomials at a massive scale, drawing on text created by millions of users. Our approach is more wholesale than prior work - we focus on all binomials of sufficient frequency, without first restricting to small samples of binomials that might be frozen. We draw our data from news publications, wine reviews, and Reddit, which in addition to large volume, also let us characterize binomials in new ways, and analyze differences in binomial orderings across communities and over time. Furthermore, the subject matter on Reddit leads to many lists about people and organizations that lets us study orderings of proper names — a key setting for word ordering which has been difficult to study by other means.\nWe also address temporal and community structure in collections of binomials. While it has been recognized that the orderings of binomials may change over time or between communities BIBREF5, BIBREF10, BIBREF1, BIBREF13, BIBREF14, BIBREF15, there has been little analysis of this change. We develop new metrics for the agreement of binomial orderings across communities and the movement of binomial orderings over time. Using subreddits as communities, these metrics reveal variations in orderings, some of which suggest cultural change influencing language. For example, in one community, we find that over a period of 10 years, the binomial `son and daughter' went from nearly frozen to appearing in that order only 64% of the time.\nWhile these changes do happen, they are generally quite rare. Most binomials — frozen or not — are ordered in one way about the same percentage of the time, regardless of community or the year. We develop a null model to determine how much variation in binomial orderings we might expect across communities and across time, if binomial orderings were randomly ordered according to global asymmetry values. We find that there is less variation across time and communities in the data compared to this model, implying that binomial orderings are indeed remarkably stable.\n We draw our data from news publications, wine reviews, and Reddit, which in addition to large volume, also let us characterize binomials in new ways, and analyze differences in binomial orderings across communities and over time. \nWe develop new metrics for the agreement of binomial orderings across communities and the movement of binomial orderings over time. Using subreddits as communities, these metrics reveal variations in orderings, some of which suggest cultural change influencing language.\nWe develop a null model to determine how much variation in binomial orderings we might expect across communities and across time, if binomial orderings were randomly ordered according to global asymmetry values.

        "question": "How do they evaluate the performances?",
        "answer": "The authors employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.",
        "evidence": "We performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty; this also allows us to compare results with our baseline. We applied a standardization of the features and we used the default configuration for parameters as described in scikit-learn package BIBREF33. We also tested other classifiers (such as K-Nearest Neighbors, Support Vector Machines and Random Forest) but we omit results as they give comparable performances. We remark that our goal is to show that a very simple machine learning framework, with no parameter tuning and optimization, allows for accurate results with our network-based approach.\nWe used the following evaluation metrics to assess the performances of different classifiers (TP=true positives, FP=false positives, FN=false negatives):\nPrecision = $\\frac{TP}{TP+FP}$, the ability of a classifier not to label as positive a negative sample.\nRecall = $\\frac{TP}{TP+FN}$, the ability of a classifier to retrieve all positive samples.\nF1-score = $2 \\frac{\\mbox{Precision} \\cdot \\mbox{Recall}}{\\mbox{Precision} + \\mbox{Recall}}$, the harmonic average of Precision and Recall.\nArea Under the Receiver Operating Characteristic curve (AUROC); the Receiver Operating Characteristic (ROC) curve BIBREF34, which plots the TP rate versus the FP rate, shows the ability of a classifier to discriminate positive samples from negative ones as its threshold is varied; the AUROC value is in the range $[0, 1]$, with the random baseline classifier holding AUROC$=0.5$ and the ideal perfect classifier AUROC$=1$; thus larger AUROC values (and steeper ROCs) correspond to better classifiers.\nIn particular we computed so-called macro average–simple unweighted mean–of these metrics evaluated considering both labels (disinformation and mainstream). We employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.\nFinally, we partitioned networks according to the total number of unique users involved in the sharing, i.e. the number of nodes in the aggregated network represented with a single-layer representation considering together all layers and also pure tweets. A breakdown of both datasets according to size class (and political biases for the US scenario) is provided in Table 1 and Table 2.\nIn Table 3 we first provide classification performances on the US dataset for the LR classifier evaluated on the size class described in Table 1. We can observe that in all instances our methodology performs better than a random classifier (50% AUROC), with AUROC values above 85% in all cases.\nFor what concerns political biases, as the classes of mainstream and disinformation networks are not balanced (e.g., 1,292 mainstream and 4,149 disinformation networks with right bias) we employ a Balanced Random Forest with default parameters (as provided in imblearn Python package BIBREF35). In order to test the robustness of our methodology, we trained only on left-biased networks or right-biased networks and tested on the entire set of sources (relative to the US dataset); we provide a comparison of AUROC values for both biases in Figure 4. We can notice that our multi-layer approach still entails significant results, thus showing that it can accurately distinguish mainstream news from disinformation regardless of the political bias. We further corroborated this result with additional classification experiments, that show similar performances, in which we excluded from the training/test set two specific sources (one at a time and both at the same time) that outweigh the others in terms of data samples–respectively \"breitbart.com\" for right-biased sources and \"politicususa.com\" for left-biased ones.\nWe performed classification experiments on the Italian dataset using the LR classifier and different size classes (we excluded $[1000, +\\infty )$ which is empty); we show results for different evaluation metrics in Table 3. We can see that despite the limited number of samples (one order of magnitude smaller than the US dataset) the performances are overall in accordance with the US scenario. As shown in Table 4, we obtain results which are much better than our baseline in all size classes (see Table 4):\nIn the US dataset our multi-layer methodology performs much better in all size classes except for large networks ($[1000, +\\infty )$ size class), reaching up to 13% improvement on smaller networks ($[0, 100)$ size class);\nIn the IT dataset our multi-layer methodology outperforms the baseline in all size classes, with the maximum performance gain (20%) on medium networks ($[100, 1000)$ size class); the baseline generally reaches bad performances compared to the US scenario.\nOverall, our performances are comparable with those achieved by two state-of-the-art deep learning models for \"fake news\" detection BIBREF9BIBREF36.\nIn order to understand the impact of each layer on the performances of classifiers, we performed additional experiments considering separately each layer (we ignored T and U features relative to pure tweets). In Table 5 we show metrics for each layer and all size classes, computed with a 10-fold stratified shuffle split cross validation, evaluated on the US dataset; in Figure 5 we show AUROC values for each layer compared with the general multi-layer approach. We can notice that both Q and M layers alone capture adequately the discrepancies of the two distinct news domains in the United States as they obtain good results with AUROC values in the range 75%-86%; these are comparable with those of the multi-layer approach which, nevertheless, outperforms them across all size classes.\nWe obtained similar performances for the Italian dataset, as the M layer obtains comparable performances w.r.t multi-layer approach with AUROC values in the range 72%-82%. We do not show these results for sake of conciseness.\nWe further investigated the importance of each feature by performing a $\\chi ^2$ test, with 10-fold stratified shuffle split cross validation, considering the entire range of network sizes $[0, +\\infty )$. We show the Top-5 most discriminative features for each country in Table 6.\nWe can notice the exact same set of features (with different relative orderings in the Top-3) in both countries; these correspond to two global network propertie–LWCC, which indicates the size of the largest cascade in the layer, and SCC, which correlates with the size of the network–associated to the same set of layers (Quotes, Retweets and Mentions).\nWe further performed a $\\chi ^2$ test to highlight the most discriminative features in the M layer of both countries, which performed equally well in the classification task as previously highlighted; also in this case we focused on the entire range of network sizes $[0, +\\infty )$. Interestingly, we discovered exactly the same set of Top-3 features in both countries, namely LWCC, SCC and DWCC (which indicates the depth of the largest cascade in the layer).\nAn inspection of the distributions of all aforementioned features revealed that disinformation news exhibit on average larger values than mainstream news.\nWe can qualitatively sum up these results as follows:\nSharing patterns in the two news domains exhibit discrepancies which might be country-independent and due to the content that is being shared.\nInteractions in disinformation sharing cascades tends to be broader and deeper than in mainstream news, as widely reported in the literature BIBREF8BIBREF2BIBREF7.\nUsers likely make a different usage of mentions when sharing news belonging to the two domains, consequently shaping different sharing patterns.\nSimilar to BIBREF9, we carried out additional experiments to answer the following question: how long do we need to observe a news spreading on Twitter in order to accurately classify it as disinformation or mainstream?\nWith this goal, we built several versions of our original dataset of multi-layer networks by considering in turn the following lifetimes: 1 hour, 6 hours, 12 hours, 1 day, 2 days, 3 days and 7 days; for each case, we computed the global network properties of the corresponding network and evaluated the LR classifier with 10-fold cross validation, separately for each lifetime (and considering always the entire set of networks). We show corresponding AUROC values for both US and IT datasets in Figure 6.\nWe can see that in both countries news diffusion networks can be accurately classified after just a few hours of spreading, with AUROC values which are larger than 80% after only 6 hours of diffusion. These results are very promising and suggest that articles pertaining to the two news domains exhibit discrepancies in their sharing patterns that can be timely exploited in order to rapidly detect misleading items from factual information.\nWe employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.",

        "question": "Based on the following passage, extract recorded instructions for housekeepers from around 100 BC.",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

        "question": "What's unique about it and why is it famous?",
        "evidence": "Doleshwor Mahadeva (Nepali: डोलेश्वर महादेव) is a Hindu Temple of Lord Shiva located in Suryabinayak, south eastern part of Bhaktapur District, Nepal, and is believed to be the head part of Kedarnath temple located in Uttarakhand, India.\n\nHistory\nFor 4000 years people have been searching for the head of the Panch Kedar temples, a bull who was Shiva in reality, who assumed the shape of a bull to avoid the five Pandava brothers, the heroes of the Mahabharat. The legend goes back to the fabled battle of Kurukshetra fought between the five Pandava brothers and their cousins, the 100 Kaurava brothers, which is the pivot of the Mahabharata. Many folk legends related to the Garhwal region, Lord Shiva and the creation of the Panch Kedar temples are narrated.\n\nA folk legend about Panch Kedar relates to the Pandavas, the heroes of the Hindu epic Mahabharata. The Pandavas defeated and slayed their cousins — the Kauravas in the epic Kurukshetra war. They wished to atone for the sins of committing fratricide (gotra hatya) and Brāhmanahatya (killing of Brahmins — the priest class) during the war. Thus, they handed over the reins of their kingdom to their kin and left in search of lord Shiva and to seek his blessings. First, they went to the holy city of Varanasi (Kashi), believed to be Shiva's favourite city and known for its Kashi Vishwanath Temple. But, Shiva wanted to avoid them as he was deeply incensed by the death and dishonesty at the Kurukshetra war and was, therefore, insensitive to Pandavas' prayers. Therefore, he assumed the form of a bull (Nandi) and hid in the Garhwal region.\n\nNot finding Shiva in Varanasi, the Pandavas went to Garhwal Himalayas. Bhima, the second of the five Pandava brothers, then standing astride two mountains started to look for Shiva. He saw a bull grazing near Guptakashi (“hidden Kashi” — the name derived from the hiding act of Shiva). Bhima immediately recognized the bull to be Shiva. Bhima caught hold of the bull by its tail and hind legs. But the bull-formed Shiva disappeared into the ground to later reappear in parts, with the hump raising in Kedarnath, the arms appearing in Tungnath, the face showing up at Rudranath, the nabhi (navel) and stomach surfacing in Madhyamaheshwar and the hair appearing in Kalpeshwar. The Pandavas pleased with this reappearance in five different forms, built temples at the five places for venerating and worshipping Shiva. The Pandavas were thus freed from their sins. It is also believed that the fore portions of Shiva appeared at Doleshwor Mahadeva Temple, Bhaktapur district Nepal.\n\nA variant of the tale credits Bhima of not only catching the bull, but also stopping it from disappearing. Consequently, the bull was torn asunder into five parts and appeared at five locations in the Kedar Khand of Garhwal region of the Himalayas. After building the Panch Kedar Temples, the Pandavas meditated at Kedarnath for salvation, performed yagna (fire sacrifice) and then through the heavenly path called the Mahapanth (also called Swargarohini), attained heaven or salvation.[citation needed]. The Panch Kedar Temples are constructed in the North-Indian Himalayan Temple architecture with the Kedarnath, Tungnath and Madhyamaheshwar temples looking similar.\n\nAfter completing the pilgrimage of Lord Shiva's darshan at the Panch Kedar Temples, it is an unwritten religious rite to visit Lord Vishnu at the Badrinath Temple, as a final affirmatory proof by the devotee that he has sought blessings of Lord Shiva.\n\nResearch and findings\nThe Hindu activist Bharat Jangam had been researching and claiming that Doleshwar Mahadev is the head part of Kedarnath based on the surprising links between Kedarnath and Doleshwor. The Sculptures of Shive found in both shrines are 4,000 years old. Even a stone scripture found in Doleshwor was written in Sanskrit and Old Nepalese. The priests in both shrines are selected from India's southern states of Karnataka, Andhra Pradesh, Kerala and Tamil Nadu. Both priests affix the word ‘ling’ after their names to convey their proximity to the god as his worshipper and both temples have a cluster of five Shiva shrines. The main deity of both priests is Birbhadra, a companion of Shiva, according to Hindu scriptures. \n\nRecognition\nOn August 22, 2009 the head priest of Kedarnath peeth Shree 1008 Jagat Guru Bheemashankarling Shivacharya unveiled the plaque claiming that Doleswore Mahadev, located in Jangam math Bhaktapur, is the head part of Shri Kedarnath. He performed Rudra Abhishek, a special worshipping at the Doleshwor temple situated in Sipadol village of Bhaktapur district. This is also mentioned in the inscription (Sheela Lekh) at Doleshwar Mahadev. Thousands of devotees have been thronging in the Doleswor Mahadev Temple.",

Our system, Gunrock BIBREF1 addresses several limitations of prior chatbots BIBREF2, BIBREF3, BIBREF4 including inconsistency and difficulty in complex sentence understanding (e.g., long utterances) and provides several contributions: First, Gunrock's multi-step language understanding modules enable the system to provide more useful information to the dialog manager, including a novel dialog act scheme. Additionally, the natural language understanding (NLU) module can handle more complex sentences, including those with coreference. Second, Gunrock interleaves actions to elicit users' opinions and provide responses to create an in-depth, engaging conversation; while a related strategy to interleave task- and non-task functions in chatbots has been proposed BIBREF5, no chatbots to our knowledge have employed a fact/opinion interleaving strategy. Finally, we use an extensive persona database to provide coherent profile information, a critical challenge in building social chatbots BIBREF3. Compared to previous systems BIBREF4, Gunrock generates more balanced conversations between human and machine by encouraging and understanding more human inputs (see Table TABREF2 for an example).\nFrom January 5, 2019 to March 5, 2019, we collected conversational data for Gunrock. During this time, no other code updates occurred. We analyzed conversations for Gunrock with at least 3 user turns to avoid conversations triggered by accident. Overall, this resulted in a total of 34,432 user conversations.

In order to proceed with our study, we needed a sizeable (few thousand) number of English speaking users with accounts on both Twitter and Facebook. We also needed to know the precise matching between the Twitter and Facebook accounts for our ground truth.\nTo that end, we crawled publicly available, English-language, Google Plus accounts using the Google Plus API and scraped links to the users' other social media profiles. (Note that one of the reasons why we used Twitter and Facebook is that they were two of the most common sites linked to on Google Plus). We used a third party social media site (i.e., Google Plus), one that was not used in our analysis to compile our ground truth in order to limit selection bias in our data collection.\nWe discarded all users who did not link to an account for both Twitter and Facebook and those whose accounts on either of these sites were not public. We then used the APIs of Twitter and Facebook to collect posts made by the users on these sites. We only collected the linguistic content and the date and time at the which the posts were made. For technical and privacy reasons, we did not collect any information from the profile of the users, such as the location, screen name, or birthday.\nOur analysis focused on activity of users for one whole year, from February 1st, 2014 to February 1st, 2015. Since we can not reliably model the behaviour patterns of users with scarce data, users with less than 20 posts in that time period on either site were discarded. Overall, we collected a dataset of $5,612$ users with each having a Facebook and Twitter account for a total of $11,224$ accounts.\nFigure 1 shows the distribution of the number of posts per user for Twitter and Facebook for our collected dataset.

        "evidence": "We provide baselines using the official train-development-test split on the following tasks: automatic speech recognition (ASR), machine translation (MT) and speech translation (ST).\nWe convert raw MP3 audio files from CoVo and TT into mono-channel waveforms, and downsample them to 16,000 Hz. For transcripts and translations, we normalize the punctuation, we tokenize the text with sacreMoses and lowercase it. For transcripts, we further remove all punctuation markers except for apostrophes. We use character vocabularies on all the tasks, with 100% coverage of all the characters. Preliminary experimentation showed that character vocabularies provided more stable training than BPE. For MT, the vocabulary is created jointly on both transcripts and translations. We extract 80-channel log-mel filterbank features, computed with a 25ms window size and 10ms window shift using torchaudio. The features are normalized to 0 mean and 1.0 standard deviation. We remove samples having more than 3,000 frames or more than 256 characters for GPU memory efficiency (less than 25 samples are removed for all languages).\nOur ASR and ST models follow the architecture in berard2018end, but have 3 decoder layers like that in pino2019harnessing. For MT, we use a Transformer base architecture BIBREF15, but with 3 encoder layers, 3 decoder layers and 0.3 dropout. We use a batch size of 10,000 frames for ASR and ST, and a batch size of 4,000 tokens for MT. We train all models using Fairseq BIBREF20 for up to 200,000 updates. We use SpecAugment BIBREF21 for ASR and ST to alleviate overfitting.\nWe use a beam size of 5 for all models. We use the best checkpoint by validation loss for MT, and average the last 5 checkpoints for ASR and ST. For MT and ST, we report case-insensitive tokenized BLEU BIBREF22 using sacreBLEU BIBREF23. For ASR, we report word error rate (WER) and character error rate (CER) using VizSeq.\nFor simplicity, we use the same model architecture for ASR and ST, although we do not leverage ASR models to pretrain ST model encoders later. Table TABREF18 shows the word error rate (WER) and character error rate (CER) for ASR models. We see that French and German perform the best given they are the two highest resource languages in CoVoST. The other languages are relatively low resource (especially Turkish and Swedish) and the ASR models are having difficulties to learn from this data.\nMT models take transcripts (without punctuation) as inputs and outputs translations (with punctuation). For simplicity, we do not change the text preprocessing methods for MT to correct this mismatch. Moreover, this mismatch also exists in cascading ST systems, where MT model inputs are the outputs of an ASR model. Table TABREF20 shows the BLEU scores of MT models. We notice that the results are consistent with what we see from ASR models. For example thanks to abundant training data, French has a decent BLEU score of 29.8/25.4. German doesn't perform well, because of less richness of content (transcripts). The other languages are low resource in CoVoST and it is difficult to train decent models without additional data or pre-training techniques.\nCoVoST is a many-to-one multilingual ST corpus. While end-to-end one-to-many and many-to-many multilingual ST models have been explored very recently BIBREF8, BIBREF9, many-to-one multilingual models, to our knowledge, have not. We hence use CoVoST to examine this setting. Table TABREF22 and TABREF23 show the BLEU scores for both bilingual and multilingual end-to-end ST models trained on CoVoST. We observe that combining speeches from multiple languages is consistently bringing gains to low-resource languages (all besides French and German). This includes combinations of distant languages, such as Ru+Fr, Tr+Fr and Zh+Fr. Moreover, some combinations do bring gains to high-resource language (French) as well: Es+Fr, Tr+Fr and Mn+Fr. We simply provide the most basic many-to-one multilingual baselines here, and leave the full exploration of the best configurations to future work. Finally, we note that for some language pairs, absolute BLEU numbers are relatively low as we restrict model training to the supervised data. We encourage the community to improve upon those baselines, for example by leveraging semi-supervised training.\nIn CoVoST, large portion of transcripts are covered by multiple speakers with different genders, accents and age groups. Besides the standard corpus-level BLEU scores, we also want to evaluate model output variance on the same content (transcript) but different speakers. We hence propose to group samples (and their sentence BLEU scores) by transcript, and then calculate average per-group mean and average coefficient of variation defined as follows:\nand\nwhere $G$ is the set of sentence BLEU scores grouped by transcript and $G^{\\prime } = \\lbrace g | g\\in G, |g|>1, \\textrm {Mean}(g) > 0 \\rbrace $.\n$\\textrm {BLEU}_{MS}$ provides a normalized quality score as oppose to corpus-level BLEU or unnormalized average of sentence BLEU. And $\\textrm {CoefVar}_{MS}$ is a standardized measure of model stability against different speakers (the lower the better). Table TABREF24 shows the $\\textrm {BLEU}_{MS}$ and $\\textrm {CoefVar}_{MS}$ of our ST models on CoVoST test set. We see that German and Persian have the worst $\\textrm {CoefVar}_{MS}$ (least stable) given their rich speaker diversity in the test set and relatively small train set (see also Figure FIGREF6 and Table TABREF2). Dutch also has poor $\\textrm {CoefVar}_{MS}$ because of the lack of training data. Multilingual models are consistantly more stable on low-resource languages. Ru+Fr, Tr+Fr, Fa+Fr and Zh+Fr even have better $\\textrm {CoefVar}_{MS}$ than all individual languages.\nWe provide baselines using the official train-development- test split on the following tasks: automatic speech recognition (ASR), machine translation (MT) and speech translation (ST).",

For instance, expletive arguments (e.g. There are birds singing) are, by definition, non-canonical arguments, and thus are a subset of add arg. However, some added arguments, such as benefactives (Bo baked Mo a cake), are not expletives. Second, some correlations can be attributed to grammatical properties of the relevant constructions. For instance, question and aux are correlated because main-clause questions in English require subject-aux inversion and in many cases the insertion of auxiliary do (Do lions meow?). Third, some correlations may be a consequence of the sources sampled in CoLA and the phenomena they focus on. For instance, the unusually high correlation of Emb-Q and ellipsis/anaphor can be attributed to BIBREF18 , which is an article about the sluicing construction involving ellipsis of an embedded interrogative (e.g. I saw someone, but I don't know who).\nExpletives, or “dummy” arguments, are semantically inert arguments. The most common expletives in English are it and there, although not all occurrences of these items are expletives. Arguments are usually selected for by the head, and they are generally not optional. In this case, the expletive occupies a syntactic argument slot, but it is not semantically selected by the verb, and there is often a syntactic variation without the expletive. See [p.170-172]adger2003core and [p.82-83]kim2008syntax.\nFor instance, question and aux are correlated because main-clause questions in English require subject-aux inversion and in many cases the insertion of auxiliary do (Do lions meow?). \nExpletives, or “dummy” arguments, are semantically inert arguments.

        "question": "Summarize how tourism impacted Hawaii in a variety of areas",
        "evidence": "Impacts of tourism in Hawaii\nEconomic\nAs Hawaii changed from a Kingdom to a Territory to a State, so too did the dominant industries change. Being a primarily agricultural land, producing around 80 percent of the world's pineapples in the 1960s, the addition of Pan Am’s flight route to Hawaii rapidly increased the number of visitors going to the islands. The years following statehood led to more than double the number of passengers arriving at Honolulu airport. As this trend continues to increase, Hawaii's economy has become heavily dependent on the tourism industry. Although the economy has seen significant growth with the addition of this industry, some researchers believe this will leave Hawaii susceptible to external economic forces. Some examples of these are an economic recession, airline strikes, or varying fuel prices which could devastate the local economy. The devastating national economic recession of 2008, hit Hawaii's tourism industry hard. In 2008, hotel occupancy dropped to 60 percent, a level not seen since the terrorist attacks in 2001.\n\nAs the economy has returned to normal levels, the tourism industry has continued to grow in Hawaii with the majority of tourists visiting Oahu, Maui, Kauai and the big island of Hawaii. Job creation is another benefit of tourism to the islands. In 2017, reports say 204,000 jobs were related to tourism. This led to $16.78 billion in visitor spending with $1.96 billion generated in tax revenue in that year alone. Resorts and the airline business are the primary benefactors of this increase in tourism.\n\nEnvironmental\nThe Sustainable Tourism Association of Hawaii (formerly the Hawaii Ecotourism Association) was founded in 1995 as a 501(c)(3) nonprofit to nurture the development of sustainable tourism in Hawaii. It offers a certification program to educate and recognize conservation-minded tour operators in Hawaii, the only such certification program of its kind in America.\n\nThe long term environmental implications that Hawaii is facing due to mass tourism has raised concern. To combat this and help raise awareness, international environmental organizations have joined forces with local island communities. There are major benefits to this type of management, usually described as \"values-led management\". By prioritizing the values and existing sustainable practices by local communities living on heavily visited islands, it preserves their interests and further respects their culture.\n\nWater\nHotels are often placed near beaches, in areas with little rainfall, and guests use 2,000 to 10,000 litres (440 to 2,200 imp gal; 530 to 2,640 US gal) of water per person. Another study concluded that on average, a single guest uses approximately 1,300 to 3,600 litres (290 to 790 imp gal; 340 to 950 US gal) of water per day, divided approximately half between accommodations (laundry and sewer) and golf courses (irrigation). This is significantly more than the average resident and has led to a number of droughts throughout the islands.\n\nLandscape\nThe number of hotel rooms from 1985 to 2010 nearly doubled from 65,000 to 132,000 rooms. Tourists visit destinations with developed infrastructure, groomed activities and pristine conditions, which boosts the economy and finances needed to uphold these facilities. On the other hand, the very creation of these institutions degrades the environmental factors tourists are drawn to. Having perfect conditions requires an amount of upkeep fueled by the revenue of the visitors but the visitors also degrade the environment at a faster rate than residents alone.\n\nA direct effect of the increase in infrastructure is the depletion of the natural landscape. As buildings are constructed the amount of natural land becomes smaller and smaller. As hotels are constructed in prime real estate the environmental problems created are not weighed equally with the potential upside of profit. The government sees the creation of jobs and the increase in visitor spending in the state as a good thing. Those are quantitative variables that can be directly measured in terms of dollars and number of jobs. However, the impact to the environment or the indigenous people is harder to measure in term of absolutes. Hawaii only holds 0.2 percent of the United States land but has a 72.1 percent extinction rate, and more than half of the natural communities in the islands are endangered by developments. An example of this is natural ponds being destroyed during construction of large buildings which were previously home to migrating birds. The ponds are no longer there, which throws off the natural flow of the ecosystem. Another staggering statistic says that nearly 60 percent of the plant and animal species in Hawaii are endangered. This includes the loss of habitats for animals and the diverse flora that gives Hawaii its beauty being degraded at an alarming rate.\n\nEnergy\nMain article: Energy in Hawaii\nHawaii has traditionally relied on fossil fuel-fired thermal power plants for its electricity generation, although it has set a statewide goal of achieving 100% of electric generation via renewable sources by 2045; as a result, the average guest uses the equivalent of 6.4 to 13 kilograms (14 to 29 lb) of oil per day, approximately 2⁄3 of which is consumed by rental car operation. For electricity alone, the average guest uses 23.9 to 33.6 kW-hr per day.\n\nRefuse\nThe beaches in Hawaii are becoming increasingly filled with trash, especially plastics. This becomes a problem not only environmentally, but also could have a negative impact on the economy as visitors come for the sandy beaches and pollutants such as trash or plastics decrease the appeal of Hawaii as a vacation destination. Kamilo Beach on the southeastern tip of the island of Hawaii has acquired the nickname \"Plastic Beach\" for its accumulation of plastic trash, much of it borne via ocean currents and trade winds from the nearby Great Pacific garbage patch. It is estimated that 15 to 20 short tons (14 to 18 t) of trash, 96% of which is plastic, washes ashore here annually.\n\nThe average guest generates approximately 3.3 kilograms (7.3 lb) of waste per day. In order to reduce the generation of plastic waste, Hawaii has begun to ban the use of single-use plastic and polystyrene foam on a county-by-county approach. A ban on polystyrene foam containers took effect in Maui County on December 31, 2018; a similar ban started in Hawaii County (the Big Island) on July 1, 2019. Oahu's ban on single-use plastic and polystyrene will take effect on January 1, 2021. Two bills were considered by the Hawaii State Legislature in early 2019, which would have been the first state-wide bans on food service plastics in America. SB367 would ban the use of polystrene foam food containers statewide; that bill died in committee in March 2019. SB522 would ban single-use plastic beverage bottles, utensils, stirring sticks, polystyrene foam containers, and straws starting in 2021; that bill was modified in committee to create a working group to make recommendations on how to reduce plastic waste instead.\n\nSocial effect\nSome Native Hawaiians believe strongly in the independence of Hawaii and the Hawaiian sovereignty movement. The creation of this grassroots organization leads to a negative view towards visitors and the disruption of the natural land. This leads to a strong contention between developers and natives who believe the land should not be transformed into a commercial or residential development. Many of these individuals are reliant on the land as a means of living. The loss of the environment affects the socio-psychological well-being of those reliant on land and marine resources. Native Hawaiians and residents alike become limited in job opportunities with a heavily skewed job-base in the tourism industry.\n\nThe essay \"Lovely Hula Lands\" (later republished as \"Lovely Hula Hands\") by native Hawaiian academic and activist Haunani-Kay Trask is severely critical of the huge influx of tourists to Hawaiʻi, which she terms a \"prostitution\" of Hawaiian culture. She ends her essay with \"let me just leave this thought behind. If you are thinking of visiting my homeland, please don't. We don't want or need any more tourists, and we certainly don't like them.\" However, the Southern Poverty Law Center (SPLC) has condemned Trask for her anti-American statements, stating that such vitriol helps fuel racism in Hawaiʻi.",

        "answer": "One example is the extracted scaling strategies for TX2, as shown in Appendix D. Specifically, we can observe that the scaled ViTs in TX2 tend to enlarge more on the linear projection ratio (r), while the linear projection ratio does not exist in the scaling factors for CNNs. So applying the CNN scaling strategies to ViT while ignoring the linear projection ratio will lead to a sub-optimal performance in terms of accuracy vs. latency on TX2 trade-off. To make it more clear, we have also modified the corresponding description in Section 3.2 in the updated manuscript.",
        "evidence": "CNN and ViT scaling factors do not match. Scaling strategies dedicated to CNNs mostly come with CNN-specific scaling factor definitions (e.g., the number of channels in convolution layers represents the model width), which cannot be directly transferred to ViT. For example, doubling (2×) the width in CNNs can be achieved via various combinations of the number of heads (h) and embedding dimension for each head (e) in ViT. Furthermore, there are extra scaling factors for ViT, e.g., the linear projection ratio (r) and the patch size (p), which do not exist in the scaling factors for CNNs but are important for ViT as shown in Appendix D, thus directly transferring the scaling strategies from CNNs to ViTs can lead to ambiguity and sub-optimal performance.\nTransformer scaling strategies for NLP is sub-optimal on ViT.  noted that for NLP, model performance (i.e., accuracy or training loss) depends \"strongly on the model scale (i.e., the number of parameters), but weakly on the model shape\". However, when scaling ViT along the factors summarized in Figure, our observations suggest that this is not true for ViT. As shown in Figure, when performing an extensive search on top of DeiT-Small following, we observe that a model's shape has a great impact on the performance. Specifically, if we change the aspect ratio, i.e., the ratio between the embedding dimension (e × h) and the number of layers (d), while keeping the model parameters to be the same, the accuracy drifts as much as 18.61%. This set of experiments motivates exploring scaling strategies dedicated to ViT. Starting from a relatively small model defined in Table, we adopt a simple iterative greedy search to perform the ViT scaling step by step, similar to the previous algorithms for exploring CNN design spaces and feature selections. Specifically, based on the starting point model or the optimal one from the previous scaling step, we scale up the model along each standalone scaling factor introduced in Section 3.1 to match the target hardware-cost (e.g., FLOPs, or latency on a specific hardware device), and select the one with the best accuracy-efficiency trade-off to be the starting point model of the next step. As analyzed in, unlike scaling strategies extracted from a specific model, scaling based on such an iterative greedy search can avoid the unscalability of the resulting scaling strategies on a specific model. Our experiments in Section 4.1 also verify that such a scaling method is simple yet effective for scaling ViT models, and only requires training a few models during each search step.\nFurthermore, there are extra scaling fac_x0002_tors for ViT, e.g., the linear projection ratio (r) and the patch size (p), which do not exist in the scaling factors for CNNs but are important for ViT as shown in Ap\u0002pendix D, thus directly transferring the scaling strategies from CNNs to ViTs can lead to ambiguity and sub-optimal perfor\u0002mance.",

Tracking these references and resolving coreference is essential for full machine comprehension of these texts. Significant progress has recently been made in reading comprehension research, due to large crowdsourced datasets BIBREF0, BIBREF1, BIBREF2, BIBREF3. However, these datasets focus largely on understanding local predicate-argument structure, with very few questions requiring long-distance entity tracking. Obtaining such questions is hard for two reasons: (1) teaching crowdworkers about coreference is challenging, with even experts disagreeing on its nuances BIBREF4, BIBREF5, BIBREF6, BIBREF7, and (2) even if we can get crowdworkers to target coreference phenomena in their questions, these questions may contain giveaways that let models arrive at the correct answer without performing the desired reasoning (see §SECREF3 for examples).\nWe introduce a new dataset, Quoref , that contains questions requiring coreferential reasoning (see examples in Figure FIGREF1). The questions are derived from paragraphs taken from a diverse set of English Wikipedia articles and are collected using an annotation process (§SECREF2) that deals with the aforementioned issues in the following ways: First, we devise a set of instructions that gets workers to find anaphoric expressions and their referents, asking questions that connect two mentions in a paragraph. These questions mostly revolve around traditional notions of coreference (Figure FIGREF1 Q1), but they can also involve referential phenomena that are more nebulous (Figure FIGREF1 Q3). Second, inspired by BIBREF8, we disallow questions that can be answered by an adversary model (uncased base BERT, BIBREF9, trained on SQuAD 1.1, BIBREF0) running in the background as the workers write questions. This adversary is not particularly skilled at answering questions requiring coreference, but can follow obvious lexical cues—it thus helps workers avoid writing questions that shortcut coreferential reasoning.\nQuoref contains more than 15K questions whose answers are spans or sets of spans in 3.5K paragraphs from English Wikipedia that can be arrived at by resolving coreference in those paragraphs. We manually analyze a sample of the dataset (§SECREF3) and find that 78% of the questions cannot be answered without resolving coreference. We also show (§SECREF4) that the best system performance is 49.1% $F_1$, while the estimated human performance is 87.2%. These findings indicate that this dataset is an appropriate benchmark for coreference-aware reading comprehension.\nWe manually analyze a sample of the dataset (§SECREF3) and find that 78% of the questions cannot be answered without resolving coreference.",

        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary",

        "evidence": "In the era of social media and networking platforms, Twitter has been doomed for abuse and harassment toward users specifically women. In fact, online harassment becomes very common in Twitter and there have been a lot of critics that Twitter has become the platform for many racists, misogynists and hate groups which can express themselves openly. Online harassment is usually in the form of verbal or graphical formats and is considered harassment, because it is neither invited nor has the consent of the receipt. Monitoring the contents including sexism and sexual harassment in traditional media is easier than monitoring on the online social media platforms like Twitter. The main reason is because of the large amount of user generated content in these media. So, the research about the automated detection of content containing sexual harassment is an important issue and could be the basis for removing that content or flagging it for human evaluation. The basic goal of this automatic classification is that it will significantly improve the process of detecting these types of hate speech on social media by reducing the time and effort required by human beings.\nPrevious studies have been focused on collecting data about sexism and racism in very broad terms or have proposed two categories of sexism as benevolent or hostile sexism BIBREF0, which undermines other types of online harassment. However, there is no much study focusing on different types online harassment alone attracting natural language processing techniques.\nIn this paper we present our work, which is a part of the SociaL Media And Harassment Competition of the ECML PKDD 2019 Conference.

        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT.",

The latter might be quite hard, but it may be worth thinking of a maximality condition for ordinary constraints (if there isn't one already)?",
        "answer": "Yes, there is such a notion in the case of the ordinary conditional independence relation (for these graphs, this is (conditional) local independence, a notion very similar to Granger causality). The paper by Mogensen and Hansen which is cited in the manuscript proves that there's a unique maximal element within each Markov equivalence class (using \\mu-separation instead of m-separation) of DMGs. As argued in that paper, this solves the maximality question as learning based on tests of local independence can output that unique graph. The paper also contains a method for visualizing the entire Markov equivalence class starting from the maximal element of the class. For generalized constraints, we agree that it seems difficult and we probably need to first better understand the generalized constraints.",
        "evidence": "A linear Hawkes process has a very simple 'mechanistic' interpretation which is evident from both the intensity representation in Definition 1 and the cluster representation (e.g., Figure). In the intensity process of β, a function φ βα concisely describes how an α-event increases the intensity with which future β-events occur. This makes Hawkes processes attractive in settings where an analyst is not merely trying to fit a process to an observed distribution but is also interested in understanding how events in some coordinate processes create events in other coordinate processes.\nExamples include social media networks, systems of interacting neurons, and alarm networks in complex engineered systems. In many applications, the observed data only include events in a proper subset of the coordinate processes of the full system.\nLocal independence has been used for structure learning in stochastic process models, analogously to how conditional independence is used for constraint-based structure learning in classical models. Structure learning based on local independence typically assumes faithfulness, that is, that X B is locally independent of X A given X C if and only if B is µ-separated from A given C in G, the DMG representing the model (µ-separation, or δ-separation, is a concept analogous to m-, or d-separation). The Markov equivalence class of G is the set of DMGs that encode exactly the same set of µ-separations, hence local independencies. show that each Markov equivalence class contains a unique maximal element and this graph is therefore a natural learning target when using tests of local independence.\nAn obvious question is therefore whether there are constraints imposed by the structure that are not described by local independence, or µ-separation. This is indeed the case and such constraints can be used to distinguish between graphical structures that imply the same set of local independencies. In the next subsection, we show that one can use the integrated mean and covariance to find such constraints. In applications, this means that the set of graphical structures that can explain the observed data may be reduced, thus we may obtain strictly more information about how coordinate processes interact.\nMogensen and Hansen (2020) show that each Markov equivalence class contains a unique maximal element and this graph is therefore a natural learning target when using tests\nof local independence.",

This information can be exploited in decision making processes but, to be useful, it should be transformed and presented in ways that make its intrinsic knowledge more readily intelligible. For that, we need efficient methods and tools that quickly extract useful information from unstructured text collections. Such demand can be observed, for instance, in Biology, where researchers, in order to be abreast of all developments, need to analyse new biomedical literature on a daily basis BIBREF2 . Another application is on fraud and corruption studies where the network information — the set of actors and their relationships — is implicitly stored in unstructured natural-language documents BIBREF3 . Hence, text mining and information extraction are required to pre-process the texts in order to extract the entities and the relations between them.\nInformation extraction is a challenging task mainly due to the ambiguous features of natural-language. Moreover, most tools need to be adapted to different human languages and to different domains BIBREF4 . In fact, the language of the processed texts is still the decisive factor when choosing among existing information extraction technologies. This is also true for the task of entity extraction (Named Entity Recognition - NER).\nFor several reasons, text mining tools are typically first developed for English and only afterwards extended to other languages. Thus, there are still relatively few text mining tools for Portuguese and even less that are freely accessible. In particular, for the named entities recognition task in Portuguese texts, we find three extractors available: Alchemy, Zemanta and Rembrandt BIBREF5 . We also find some studies where the measures ( INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ) for those extractors are computed and compared BIBREF6 , but their comparative effectiveness remains domain and final purpose dependent.\nIn this work, we present PAMPO (PAttern Matching and POs tagging based algorithm for NER), a new method to automatically extract named entities from unstructured texts, applicable to the Portuguese language but potentially adaptable to other languages as well. The method relies on flexible pattern matching, part-of-speech tagging and lexical-based rules. All steps are implemented using free software and taking advantage of various existing packages.\nThe process has been developed using as case-study a specific book written in Portuguese, but it has since been used in other applications and successfully tested in different text collections. In this paper, we describe the evaluation procedures on independent textual collections, and produce a comparative study of PAMPO with other existing tools for NER.\nIn particular, for the named entities recognition task in Portuguese texts, we find three extractors available: Alchemy, Zemanta and Rembrandt .",

        "evidence": "CLIR systems retrieve documents written in a language that is different from search query language BIBREF0 . The primary objective of CLIR is to translate or project a query into the language of the document repository BIBREF1 , which we refer to as Retrieval Corpus (RC). To this end, common CLIR approaches translate search queries using a Machine Translation (MT) model and then use a monolingual IR system to retrieve from RC. In this process, a translation model is treated as a black box BIBREF2 , and it is usually trained on a sentence level parallel corpus, which we refer to as Translation Corpus (TC).\nWe address a pitfall of using existing MT models for query translation BIBREF1 . An MT model trained on TC does not have any knowledge of RC. In an extreme setting, where there are no common terms between the target side of TC and RC, a well trained and tested translation model would fail because of vocabulary mismatch between the translated query and documents of RC. Assuming a relaxed scenario where some commonality exists between two corpora, a translation model might still perform poorly, favoring terms that are more likely in TC but rare in RC. Our hypothesis is that a search query translation model would perform better if a translated query term is likely to appear in the both retrieval and translation corpora, a property we call balanced translation.\nTo achieve balanced translations, it is desired to construct an MT model that is aware of RC vocabulary. Different types of MT approaches have been adopted for CLIR task, such as dictionary-based MT, rule-based MT, statistical MT etc. BIBREF3 . However, to the best of our knowledge, a neural search query translation approach has yet to be taken by the community. NMT models with attention based encoder-decoder techniques have achieved state-of-the-art performance for several language pairs BIBREF4 . We propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT). RAT is inspired from two word embedding learning approaches: Relevance-based Word Embedding (RWE) BIBREF5 and Continuous Bag of Words (CBOW) embedding BIBREF6 . We show that learning NMT with RAT enables it to generate balanced translation.\nNMT models learn to encode the meaning of a source sentence and decode the meaning to generate words in a target language BIBREF7 . In the proposed multi-task learning model, RAT shares the decoder embedding and final representation layer with NMT. Our architecture answers the following question: In the decoding stage, can we restrict an NMT model so that it does not only generate terms that are highly likely in TC?. We show that training a strong baseline NMT with RAT roughly achieves 16% improvement over the baseline. Using a qualitative analysis, we further show that RAT works as a regularizer and prohibits NMT to overfit to TC vocabulary.\nWe show that training a strong baseline NMT with RAT arXiv:1906.06849v1 [cs.IR] 17 Jun 2019 roughly achieves 16% improvement over the baseline.

        "evidence": "The pre-trained language model, BERT BIBREF0 has led to a big breakthrough in various kinds of natural language understanding tasks. Ideally, people can start from a pre-trained BERT checkpoint and fine-tune it on a specific downstream task. However, the original BERT models are memory-exhaustive and latency-prohibitive to be served in embedded devices or CPU-based online environments. As the memory and latency constraints vary in different scenarios, the pre-trained BERT model should be adaptive to different requirements with accuracy retained to the largest extent. Existing BERT-oriented model compression solutions largely depend on knowledge distillation BIBREF1, which is inefficient and resource-consuming because a large training corpus is required to learn the behaviors of a teacher. For example, DistilBERT BIBREF2 is re-trained on the same corpus as pre-training a vanilla BERT from scratch; and TinyBERT BIBREF3 utilizes expensive data augmentation to fit the distillation target. The costs of these model compression methods are as large as pre-training and unaffordable for low-resource settings. Therefore, it is straight-forward to ask, can we design a lightweight method to generate adaptive models with comparable accuracy using significantly less time and resource consumption? In this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions. Specifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation. Initially, the architecture and weights of student model are inherited from the BERT teacher. In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation. Because weight pruning and matrix factorization help to generate better initial and intermediate status\nin the knowledge distillation iterations, the accuracy and efficiency of model compression can be greatly improved.\nWe conduct extensive experiments on five public datasets of natural language understanding. As an example, the performance comparison of LadaBERT and state-of-the-art models on MNLI-m dataset is illustrated in Figure FIGREF1. We can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios. Especially, LadaBERT-1 outperforms BERT-PKD significantly under $2.5\\times $ compression ratio, and LadaBERT-3 outperforms TinyBERT under $7.5\\times $ compression ratio while the training speed is accelerated by an order of magnitude.\nThe rest of this paper is organized as follows. First, we summarizes the related works of model compression and their applications to BERT in Section SECREF2. Then, the methodology of LadaBERT is introduced in Section SECREF3, and experimental results are presented in Section SECREF4. At last, we conclude this work and discuss future works in Section SECREF5.\nSpecifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation.",

        "question": "Inspired by what they use deep reinforcement learning methods to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample?",
        "answer": "ReasoNet and dynamic neural module networks",
        "evidence": "The goal of Machine Reading Comprehension (MRC) is to have machines read a text passage and then generate an answer (or select an answer from a list of given candidates) for any question about the passage. There has been a growing interest in the research community in exploring neural MRC models in an end-to-end fashion, thanks to the availability of large-scale datasets, such as CNN/DM BIBREF0 and SQuAD BIBREF1 .\nDespite the variation in model structures, most state-of-the-art models perform reading comprehension in two stages. First, the symbolic representations of passages and questions are mapped into vectors in a neural space. This is commonly achieved via embedding and attention BIBREF2 , BIBREF3 or fusion BIBREF4 . Then, reasoning is performed on the vectors to generate the right answer.\nIdeally, the best attention and reasoning strategies should adapt organically in order to answer different questions. However, most MRC models use a static attention and reasoning strategy indiscriminately, regardless of various question types. One hypothesis is because these models are optimized on those datasets whose passages and questions are domain-specific (or of a single type). For example, in CNN/DM, all the passages are news articles, and the answer to each question is an entity in the passage. In SQuAD, the passages came from Wikipedia articles and the answer to each question is a text span in the article. Such a fixed-strategy MRC model does not adapt well to other datasets. For example, the exact-match score of BiDAF BIBREF2 , one of the best models on SQuAD, drops from 81.5 to 55.8 when applied to TriviaQA BIBREF5 , whereas human performance is 82.3 and 79.7 on SQuAD and TriviaQA, respectively.\nIn real-world MRC tasks, we must deal with questions and passages of different types and complexities, which calls for models that can dynamically determine what attention and reasoning strategy to use for any input question-passage pair on the fly. In a recent paper, BIBREF6 proposed dynamic multi-step reasoning, where the number of reasoning steps is determined spontaneously (using reinforcement learning) based on the complexity of the input question and passage. With a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.\nThe proposed model is called a Dynamic Fusion Network (DFN). In this paper, we describe the version of DFN developed on the RACE dataset BIBREF7 . In RACE, a list of candidate answers is provided for each passage-question pair. So DFN for RACE is a scoring model - the answer candidate with the highest score will be selected as the final answer.\nLike other MRC models, DFNs also perform machine reading in two stages: attention and reasoning. DFN is unique in its use of a dynamic multi-strategy attention process in the attention stage. Here “attention” refers to the process that texts from different sources (passage, question, answers) are combined in the network. In literature, a fixed attention mechanism is usually employed in MRC models. In DFN, the attention strategy is not static; instead, the actual strategy for drawing attention among the three text sources are chosen on the fly for each sample. This lends flexibility to adapt to various question types that require different comprehension skills. The output of the attention stage is then fed into the reasoning module to generate the answer score. The reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.\nInspired by ReasoNet BIBREF6 and dynamic neural module networks BIBREF8 , we use deep reinforcement learning methods BIBREF9 , BIBREF10 to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample. We use RL in favor of other simpler methods (like cascading, pooling or weighted averaging) mainly because we intend to learn a policy that constructs an instance of DFN of a sample-specific structure. Given an input sample consisting of a question, a passage and a list of candidate answers in RACE, an instance of DFN can be constructed via RL step by step on the fly. Such a policy is particularly appealing as it also provides insights on how the model performs on different types of questions. At each decision step, the policy maps its “state”, which represents an input sample, and DFN's partial knowledge of the right answer, to the action of assembling proper attention and reasoning modules for DFN.\nExperiments conducted on the RACE dataset show that DFN significantly outperforms previous state-of-the-art MRC models and has achieved the best result reported on RACE. A thorough empirical analysis also demonstrates that DFN is highly effective in understanding passages of a wide variety of styles and answering questions of different complexities.\nInspired by ReasoNet (Shen et al., 2017) and dynamic neural module networks (Andreas et al., 2016), we use deep reinforcement learning methods (Mnih et al., 2013; Zhang et al., 2017) to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample.",

        "evidence": "We performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty; this also allows us to compare results with our baseline. We applied a standardization of the features and we used the default configuration for parameters as described in scikit-learn package BIBREF33. We also tested other classifiers (such as K-Nearest Neighbors, Support Vector Machines and Random Forest) but we omit results as they give comparable performances. We remark that our goal is to show that a very simple machine learning framework, with no parameter tuning and optimization, allows for accurate results with our network-based approach.\nWe used the following evaluation metrics to assess the performances of different classifiers (TP=true positives, FP=false positives, FN=false negatives):\nPrecision = $\\frac{TP}{TP+FP}$, the ability of a classifier not to label as positive a negative sample.\nRecall = $\\frac{TP}{TP+FN}$, the ability of a classifier to retrieve all positive samples.\nF1-score = $2 \\frac{\\mbox{Precision} \\cdot \\mbox{Recall}}{\\mbox{Precision} + \\mbox{Recall}}$, the harmonic average of Precision and Recall.\nArea Under the Receiver Operating Characteristic curve (AUROC); the Receiver Operating Characteristic (ROC) curve BIBREF34, which plots the TP rate versus the FP rate, shows the ability of a classifier to discriminate positive samples from negative ones as its threshold is varied; the AUROC value is in the range $[0, 1]$, with the random baseline classifier holding AUROC$=0.5$ and the ideal perfect classifier AUROC$=1$; thus larger AUROC values (and steeper ROCs) correspond to better classifiers.\nIn particular we computed so-called macro average–simple unweighted mean–of these metrics evaluated considering both labels (disinformation and mainstream). We employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.\nFinally, we partitioned networks according to the total number of unique users involved in the sharing, i.e. the number of nodes in the aggregated network represented with a single-layer representation considering together all layers and also pure tweets. A breakdown of both datasets according to size class (and political biases for the US scenario) is provided in Table 1 and Table 2.\nIn Table 3 we first provide classification performances on the US dataset for the LR classifier evaluated on the size class described in Table 1. We can observe that in all instances our methodology performs better than a random classifier (50% AUROC), with AUROC values above 85% in all cases.\nFor what concerns political biases, as the classes of mainstream and disinformation networks are not balanced (e.g., 1,292 mainstream and 4,149 disinformation networks with right bias) we employ a Balanced Random Forest with default parameters (as provided in imblearn Python package BIBREF35). In order to test the robustness of our methodology, we trained only on left-biased networks or right-biased networks and tested on the entire set of sources (relative to the US dataset); we provide a comparison of AUROC values for both biases in Figure 4. We can notice that our multi-layer approach still entails significant results, thus showing that it can accurately distinguish mainstream news from disinformation regardless of the political bias. We further corroborated this result with additional classification experiments, that show similar performances, in which we excluded from the training/test set two specific sources (one at a time and both at the same time) that outweigh the others in terms of data samples–respectively \"breitbart.com\" for right-biased sources and \"politicususa.com\" for left-biased ones.\nWe performed classification experiments on the Italian dataset using the LR classifier and different size classes (we excluded $[1000, +\\infty )$ which is empty); we show results for different evaluation metrics in Table 3. We can see that despite the limited number of samples (one order of magnitude smaller than the US dataset) the performances are overall in accordance with the US scenario. As shown in Table 4, we obtain results which are much better than our baseline in all size classes (see Table 4):\nIn the US dataset our multi-layer methodology performs much better in all size classes except for large networks ($[1000, +\\infty )$ size class), reaching up to 13% improvement on smaller networks ($[0, 100)$ size class);\nIn the IT dataset our multi-layer methodology outperforms the baseline in all size classes, with the maximum performance gain (20%) on medium networks ($[100, 1000)$ size class); the baseline generally reaches bad performances compared to the US scenario.\nOverall, our performances are comparable with those achieved by two state-of-the-art deep learning models for \"fake news\" detection BIBREF9BIBREF36.\nIn order to understand the impact of each layer on the performances of classifiers, we performed additional experiments considering separately each layer (we ignored T and U features relative to pure tweets). In Table 5 we show metrics for each layer and all size classes, computed with a 10-fold stratified shuffle split cross validation, evaluated on the US dataset; in Figure 5 we show AUROC values for each layer compared with the general multi-layer approach. We can notice that both Q and M layers alone capture adequately the discrepancies of the two distinct news domains in the United States as they obtain good results with AUROC values in the range 75%-86%; these are comparable with those of the multi-layer approach which, nevertheless, outperforms them across all size classes.\nWe obtained similar performances for the Italian dataset, as the M layer obtains comparable performances w.r.t multi-layer approach with AUROC values in the range 72%-82%. We do not show these results for sake of conciseness.\nWe further investigated the importance of each feature by performing a $\\chi ^2$ test, with 10-fold stratified shuffle split cross validation, considering the entire range of network sizes $[0, +\\infty )$. We show the Top-5 most discriminative features for each country in Table 6.\nWe can notice the exact same set of features (with different relative orderings in the Top-3) in both countries; these correspond to two global network propertie–LWCC, which indicates the size of the largest cascade in the layer, and SCC, which correlates with the size of the network–associated to the same set of layers (Quotes, Retweets and Mentions).\nWe further performed a $\\chi ^2$ test to highlight the most discriminative features in the M layer of both countries, which performed equally well in the classification task as previously highlighted; also in this case we focused on the entire range of network sizes $[0, +\\infty )$. Interestingly, we discovered exactly the same set of Top-3 features in both countries, namely LWCC, SCC and DWCC (which indicates the depth of the largest cascade in the layer).\nAn inspection of the distributions of all aforementioned features revealed that disinformation news exhibit on average larger values than mainstream news.\nWe can qualitatively sum up these results as follows:\nSharing patterns in the two news domains exhibit discrepancies which might be country-independent and due to the content that is being shared.\nInteractions in disinformation sharing cascades tends to be broader and deeper than in mainstream news, as widely reported in the literature BIBREF8BIBREF2BIBREF7.\nUsers likely make a different usage of mentions when sharing news belonging to the two domains, consequently shaping different sharing patterns.\nSimilar to BIBREF9, we carried out additional experiments to answer the following question: how long do we need to observe a news spreading on Twitter in order to accurately classify it as disinformation or mainstream?\nWith this goal, we built several versions of our original dataset of multi-layer networks by considering in turn the following lifetimes: 1 hour, 6 hours, 12 hours, 1 day, 2 days, 3 days and 7 days; for each case, we computed the global network properties of the corresponding network and evaluated the LR classifier with 10-fold cross validation, separately for each lifetime (and considering always the entire set of networks). We show corresponding AUROC values for both US and IT datasets in Figure 6.\nWe can see that in both countries news diffusion networks can be accurately classified after just a few hours of spreading, with AUROC values which are larger than 80% after only 6 hours of diffusion. These results are very promising and suggest that articles pertaining to the two news domains exhibit discrepancies in their sharing patterns that can be timely exploited in order to rapidly detect misleading items from factual information.\nWe can notice that our multi-layer approach still entails significant results, thus showing that it can accurately distinguish mainstream news from disinformation regardless of the political bias.",

        "evidence": "CLIR systems retrieve documents written in a language that is different from search query language BIBREF0 . The primary objective of CLIR is to translate or project a query into the language of the document repository BIBREF1 , which we refer to as Retrieval Corpus (RC). To this end, common CLIR approaches translate search queries using a Machine Translation (MT) model and then use a monolingual IR system to retrieve from RC. In this process, a translation model is treated as a black box BIBREF2 , and it is usually trained on a sentence level parallel corpus, which we refer to as Translation Corpus (TC).\nWe address a pitfall of using existing MT models for query translation BIBREF1 . An MT model trained on TC does not have any knowledge of RC. In an extreme setting, where there are no common terms between the target side of TC and RC, a well trained and tested translation model would fail because of vocabulary mismatch between the translated query and documents of RC. Assuming a relaxed scenario where some commonality exists between two corpora, a translation model might still perform poorly, favoring terms that are more likely in TC but rare in RC. Our hypothesis is that a search query translation model would perform better if a translated query term is likely to appear in the both retrieval and translation corpora, a property we call balanced translation.\nTo achieve balanced translations, it is desired to construct an MT model that is aware of RC vocabulary. Different types of MT approaches have been adopted for CLIR task, such as dictionary-based MT, rule-based MT, statistical MT etc. BIBREF3 . However, to the best of our knowledge, a neural search query translation approach has yet to be taken by the community. NMT models with attention based encoder-decoder techniques have achieved state-of-the-art performance for several language pairs BIBREF4 . We propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT). RAT is inspired from two word embedding learning approaches: Relevance-based Word Embedding (RWE) BIBREF5 and Continuous Bag of Words (CBOW) embedding BIBREF6 . We show that learning NMT with RAT enables it to generate balanced translation.\nNMT models learn to encode the meaning of a source sentence and decode the meaning to generate words in a target language BIBREF7 . In the proposed multi-task learning model, RAT shares the decoder embedding and final representation layer with NMT. Our architecture answers the following question: In the decoding stage, can we restrict an NMT model so that it does not only generate terms that are highly likely in TC?. We show that training a strong baseline NMT with RAT roughly achieves 16% improvement over the baseline. Using a qualitative analysis, we further show that RAT works as a regularizer and prohibits NMT to overfit to TC vocabulary.\nWe propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT).",

It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. As of 2019, Java was one of the most popular programming languages in use according to GitHub,[citation not found] particularly for client–server web applications, with a reported 9 million developers.\n\nJava was originally developed by James Gosling at Sun Microsystems. It was released in May 1995 as a core component of Sun Microsystems' Java platform. The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses. As of May 2007, in compliance with the specifications of the Java Community Process, Sun had relicensed most of its Java technologies under the GPL-2.0-only license. Oracle offers its own HotSpot Java Virtual Machine, however the official reference implementation is the OpenJDK JVM which is free open-source software and used by most developers and is the default JVM for almost all Linux distributions.\n\nAs of March 2023, Java 20 is the latest version, while Java 17, 11 and 8 are the current long-term support (LTS) versions.",

        "question": "What do they design a selective gate to do?",
        "answer": "To aggregate sentence-level representations into bag-level one and alleviate intrinsic issues appearing in selective attention.",
        "evidence": "Relation extraction (RE) is one of the most fundamental tasks in natural language processing, and its goal is to identify the relationship between a given pair of entities in a sentence. Typically, a large-scale training dataset with clean labels is required to train a reliable relation extraction model. However, it is time-consuming and labor-intensive to annotate such data by crowdsourcing. To overcome the lack of labeled training data, BIBREF0 mintz2009distant presents a distant supervision approach that automatically generates a large-scale, labeled training set by aligning entities in knowledge graph (e.g. Freebase BIBREF1) to corresponding entity mentions in natural language sentences. This approach is based on a strong assumption that, any sentence containing two entities should be labeled according to the relationship of the two entities on the given knowledge graph. However, this assumption does not always hold. Sometimes the same two entities in different sentences with various contexts cannot express a consistent relationship as described in the knowledge graph, which certainly results in wrongly labeled problem.\nTo alleviate the aformentioned problem, BIBREF2 riedel2010modeling proposes a multi-instance learning framework, which relaxes the strong assumption to expressed-at-least-one assumption. In plainer terms, this means any possible relation between two entities hold true in at least one distantly-labeled sentence rather than all of the them that contains those two entities. In particular, instead of generating a sentence-level label, this framework assigns a label to a bag of sentences containing a common entity pair, and the label is a relationship of the entity pair on knowledge graph. Recently, based on the labeled data at bag level, a line of works BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 under selective attention framework BIBREF5 let model implicitly focus on the correctly labeled sentence(s) by an attention mechanism and thus learn a stable and robust model from the noisy data.\nHowever, such selective attention framework is vulnerable to situations where a bag is merely comprised of one single sentence labeled; and what is worse, the only one sentence possibly expresses inconsistent relation information with the bag-level label. This scenario is not uncommon. For a popular distantly supervised relation extraction benchmark, e.g., NYT dataset BIBREF2, up to $80\\%$ of its training examples (i.e., bags) are one-sentence bags. From our data inspection, we randomly sample 100 one-sentence bags and find $35\\%$ of them is incorrectly labeled. Two examples of one-sentence bag are shown in Table TABREF1. These results indicate that, in training phrase the selective attention module is enforced to output a single-valued scalar for $80\\%$ examples, leading to an ill-trained attention module and thus hurting the performance.\nMotivated by aforementioned observations, in this paper, we propose a novel Selective Gate (SeG) framework for distantly supervised relation extraction. In the proposed framework, 1) we employ both the entity embeddings and relative position embeddings BIBREF8 for relation extraction, and an entity-aware embedding approach is proposed to dynamically integrate entity information into each word embedding, yielding more expressively-powerful representations for downstream modules; 2) to strengthen the capability of widely-used piecewise CNN (PCNN) BIBREF3 on capturing long-term dependency BIBREF9, we develop a light-weight self-attention BIBREF10, BIBREF11 mechanism to capture rich dependency information and consequently enhance the capability of neural network via producing complementary representation for PCNN; and 3) based on preceding versatile features, we design a selective gate to aggregate sentence-level representations into bag-level one and alleviate intrinsic issues appearing in selective attention.\nCompared to the baseline framework (i.e., selective attention for multi-instance learning), SeG is able to produce entity-aware embeddings and rich-contextual representations to facilitate downstream aggregation modules that stably learn from noisy training data. Moreover, SeG uses gate mechanism with pooling to overcome problem occurring in selective attention, which is caused by one-sentence bags. In addition, it still keeps a light-weight structure to ensure the scalability of this model.\nThe experiments and extensive ablation studies on New York Time dataset BIBREF2 show that our proposed framework achieves a new state-of-the-art performance regarding both AUC and top-n precision metrics for distantly supervised relation extraction task, and also verify the significance of each proposed module. Particularly, the proposed framework can achieve AUC of 0.51, which outperforms selective attention baseline by 0.14 and improves previous state-of-the-art approach by 0.09.\nand 3) based on preceding versatile features, we design a selective gate to aggregate sentence-level representations into bag-level one and alleviate intrinsic issues appearing in selective attention.",

        "evidence": "Back to 42 BC, the philosopher Cicero has raised the issue that although there were many Oratory classes, there were none for Conversational skills BIBREF0 . He highlighted how important they were not only for politics, but also for educational purpose. Among other conversational norms, he claimed that people should be able to know when to talk in a conversation, what to talk depending on the subject of the conversation, and that they should not talk about themselves.\nNorms such as these may become social conventions and are not learnt at home or at school. Social conventions are dynamic and may change according to context, culture and language. In online communication, new commonsense practices are evolved faster and accepted as a norm BIBREF1 , BIBREF2 . There is not a discipline for that on elementary or high schools and there are few linguistics researchers doing research on this field.\nOn the other hand, within the Artificial Intelligence area, some Conversational Systems have been created in the past decades since the test proposed by Alan Turing in 1950. The test consists of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from that of a human BIBREF3 . Turing proposed that a human evaluator would judge natural language conversations between a human and a machine that is designed to generate human-like responses. Since then, many systems have been created to pass the Turing's test. Some of them have won prizes, some not BIBREF4 . Although in this paper we do not focus on creating a solution that is able to build conversational systems that pass the Turing's test, we focus on NDS. From BIBREF5 , \"NDS are systems that try to improve usability and user satisfaction by imitating human behavior\". We refer to Conversational Systems as NDS, where the dialogues are expressed as natural language texts, either from artificial intelligent agents (a.k.a. bots) or from humans.\nThat said, the current popular name to systems that have the ability to make a conversation with humans using natural language is Chatbot. Chatbots are typically used in conversational systems for various practical purposes, including customer service or information acquisition. Chatbots are becoming more widely used by social media software vendors. For example, Facebook recently announced that it would make Facebook Messenger (its 900-million-user messaging app by 2016), into a full-fledged platform that allows businesses to communicate with users via chatbots. Google is also building a new mobile-messaging service that uses artificial intelligence know-how and chatbot technology. In addition, according to the Wall Street Journal, there are more than 2 billion users of mobile apps. Still, people can be reluctant to install apps. So it is believed that social messaging can be a platform and chatbots may provide a new conversational interface for interacting with online services, as chatbots are easier to build and deploy than apps BIBREF6 .\nChina seems to be the place where chatbots adoption and use is most advanced today. For example, China's popular WeChat messaging platform can take payments, scan QR codes, and integrate chatbot systems. WeChat integrates e-mail, chat, videocalls and sharing of large multimedia files. Users can book flights or hotels using a mixed, multimedia interaction with active bots. WeChat was first released in 2011 by Tecent, a Chinese online-gaming and social-media firm, and today more than 700 million people use it, being one of the most popular messaging apps in the world (The Economist 2016). WeChat has a mixture of real-live customer service agents and automated replies (Olson 2016).\nStill, current existing chatbot engines do not properly handle a group chat with many users and many chatbots. This makes the chatbots considerably less social, which is a problem since there is a strong demand of having social chatbots that are able to provide different kinds of services, from traveling packages to finance advisors. This happens because there is a lack of methods and tools to design and engineer the coordination and mediation among chatbots and humans, as we present in Sections 2 and 3. In this paper, we refer to conversational systems that are able to interact with one or more people or chatbots in a multi-party chat as MPCS. Altogether, this paper is not meant to advance the state of the art on the norms for MPCS. Instead, the main contributions of this paper are threefold:\nWe then present some discussion and future work in the last section.\nInstead, the main contributions of this paper are threefold: 1. We discuss the challenges of designing and building MPCS (Section 2), 2. We categorize the state of the art with works that tackle each of the challenges somehow (Section 3), 3.

        "evidence": "In the research field of Natural Language Processing (NLP) there are several tasks that contribute to understanding natural text. These tasks can manipulate natural language, such as tokenization process, and consequently can be used in other implementations, in order to extract syntactic or semantic information. One such task for syntactic components is Part of Speech Tagging (POS Tagging). Part of Speech Tagging in corpus linguistics is a process where a word is assigned with a label of the grammatical term, given the context it appears in. In many languages, POS Tagging models achieve an accuracy of 96 to 97 percent BIBREF0.\nPart of Speech Tagging for highly inflective languages, such as Greek is quite a difficult task. In the Greek Language, words can have different morphological forms, depending on the part of speech (verbs have up to ten different forms). For that purpose, there is a need for a tagset that can support morphological features for improvement of Greek POS Tagging BIBREF1.\nAnother main task for extracting semantic information is Named Entity Recognition (NER). Named Entity Recognition is a process where a word or a set of words reference to a world object. Most Natural Language Processing models classify named entities that describe people, locations, organizations, following the ENAMEX type or can be more complex by detecting numerical types, like percentages (NUMEX) or dates (TIMEX) BIBREF2.\nThe greek Part of Speech Tagging and Named Entity Recognition models presented in this paper were developed using the spaCy library BIBREF3. SpaCy is an open source, Natural Language Processing library that supports a variety of tasks, including POS Tagging, Named Entity Recognition, Dependency Parsing, etc. SpaCy uses sophisticated neural network-based models for the implementation of Natural Language Processing components that achieve state-of-the-art results in many of these tasks.\nIn the following chapters the process for implementing Part of Speech Tagging and Named Entity Recognition for the Greek Language is explained. A dataset with extended POS Tags was found and matched to a set of morphological rules, according to a treebank. The dataset was then processed, fed to the spaCy model and used for training. Similarly, for Named Entity Recognition, datasets from different sources were compared to a custom set of rules for named entities. Finally, different experiments were conducted for evaluating the accuracy of the models.\nA dataset with extended POS Tags was found and matched to a set of morphological rules, according to a treebank.

So much so that it is easy to overlook their potential to benefit society by promoting equity, diversity, and fairness. For example, machines do not take bribes to do their jobs, they can determine eligibility for a loan without being influenced by the color of the applicant's skin, and they can provide access to information and services without discrimination based on gender or sexual orientation. Nonetheless, as machine learning systems become more human-like in their predictions, they can also perpetuate human biases. Some learned biases may be beneficial for the downstream application (e.g., learning that humans often use some insect names, such as spider or cockroach, to refer to unpleasant situations). Other biases can be inappropriate and result in negative experiences for some groups of people. Examples include, loan eligibility and crime recidivism prediction systems that negatively assess people belonging to a certain pin/zip code (which may disproportionately impact people of a certain race) BIBREF0 and resumé sorting systems that believe that men are more qualified to be programmers than women BIBREF1 . Similarly, sentiment and emotion analysis systems can also perpetuate and accentuate inappropriate human biases, e.g., systems that consider utterances from one race or gender to be less positive simply because of their race or gender, or customer support systems that prioritize a call from an angry male over a call from the equally angry female.\nPredictions of machine learning systems have also been shown to be of higher quality when dealing with information from some groups of people as opposed to other groups of people. For example, in the area of computer vision, gender classification systems perform particularly poorly for darker skinned females BIBREF2 . Natural language processing (NLP) systems have been shown to be poor in understanding text produced by people belonging to certain races BIBREF3 , BIBREF4 . For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.\nEven though there is some recent work highlighting such inappropriate biases (such as the work mentioned above), each such past work has largely focused on just one or two systems and resources. Further, there is no benchmark dataset for examining inappropriate biases in natural language systems. In this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC). We used the EEC as a supplementary test set in a recent shared task on predicting sentiment and emotion intensity in tweets, SemEval-2018 Task 1: Affect in Tweets BIBREF5 . In particular, we wanted to test a hypothesis that a system should equally rate the intensity of the emotion expressed by two sentences that differ only in the gender/race of a person mentioned. Note that here the term system refers to the combination of a machine learning architecture trained on a labeled dataset, and possibly using additional language resources. The bias can originate from any or several of these parts. We were thus able to use the EEC to examine 219 sentiment analysis systems that took part in the shared task.\nWe compare emotion and sentiment intensity scores that the systems predict on pairs of sentences in the EEC that differ only in one word corresponding to race or gender (e.g., `This man made me feel angry' vs. `This woman made me feel angry'). We find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender. We also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.\nDespite the work we describe here and what others have proposed in the past, it should be noted that there are no simple solutions for dealing with inappropriate human biases that percolate into machine learning systems. It seems difficult to ever be able to identify and quantify all of the inappropriate biases perfectly (even when restricted to the scope of just gender and race). Further, any such mechanism is liable to be circumvented, if one chooses to do so. Nonetheless, as developers of sentiment analysis systems, and NLP systems more broadly, we cannot absolve ourselves of the ethical implications of the systems we build. Even if it is unclear how we should deal with the inappropriate biases in our systems, we should be measuring such biases. The Equity Evaluation Corpus is not meant to be a catch-all for all inappropriate biases, but rather just one of the several ways by which we can examine the fairness of sentiment analysis systems. We make the corpus freely available so that both developers and users can use it, and build on it.\nIn this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC).",

        "answer": "A transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT and some new supervised fine-tuning strategies.",
        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets.",

The procedure is applied to the train, validation and test sets. For the resulting dataset generated for each setting, we compare models having access to text-only context versus additional text and multimodal contexts. We seek to get insights into the contribution of each type of context to address each type of degradation.\nIn this setting (RND) we simulate erroneous source words by randomly dropping source content words. We first tag the entire source sentences using the spacy toolkit BIBREF26 and then drop nouns, verbs, adjectives and adverbs and replace these with a default BLANK token. By focusing on content words, we differ from previous work that suggests that neural machine translation is robust to non-content word noise in the source BIBREF27 .\nIn this setting (AMB), we rely on the MLT dataset BIBREF11 which provides a list of source words with multiple translations in the Multi30k training set. We replace ambiguous words with the BLANK token in the source language, which results in two language-specific datasets.\nIn this setting (PERS), we use the Flickr Entities dataset BIBREF28 to identify all the words that were annotated by humans as corresponding to the category person. We then replace such source words with the BLANK token.\nThe statistics of the resulting datasets for the three degradation strategies are shown in Table TABREF10 .

As we explain on Pg. 2, shaper has its own distinct objective which seeks to improve the return for controller and, its own policy. This enables Shaper to introduce shaping rewards that promote complex exploration patterns. Crucially, the switching control aspect of Shaper’s intervention means that it can choose not to add shaping rewards at states that are not helpful.",
        "evidence": "Reinforcement learning (RL) offers the potential for autonomous agents to learn complex behaviours without the need for human intervention. Despite the notable success of RL in a variety domains, enabling RL algorithms to learn successfully in numerous real-world tasks remains a challenge. A key obstacle to the success of RL algorithms is the requirement of a rich reward signal that can guide the agent towards an optimal policy. In many settings of interest such as physical tasks and video games, rich informative signals of the agent's performance are not readily available. For example, in the video game Super Mario, the agent must perform sequences of hundreds of actions while receiving no rewards for it to successfully complete its task. In this setting, the sparse reward provides infrequent feedback of the agent's performance. This leads to RL algorithms requiring large numbers of samples (and high expense) for solving problems. Consequently, there is great need for RL techniques that solve these problems efficiently.\nVarious biological systems have mechanisms that produce rewards for activities that present little or no direct biological utility. Such mechanisms, which have been fashioned over millions of years are designed to provide intrinsic rewards to promote behaviours that improve chances of outcomes with biological utility. In RL, reward shaping (RS) is a tool to introduce intrinsic rewards known as shaping rewards that supplement environment reward signals. These rewards can encourage exploration and insert structural knowledge in the absence of informative environment rewards which can improve learning outcomes. In general however, RS algorithms assume hand-crafted and domainspecific shaping functions whose construction is typically highly labour intensive. This runs contrary to the aim of autonomous learning. Moreover, poor choices of shaping rewards can worsen the agent's performance. To resolve these issues, a useful shaping reward must be obtained autonomously.\nInspired by naturally occurring systems, we tackle the problem of sparse and uninformative rewards by developing a framework that autonomously constructs shaping rewards during learning. Our framework, ROSA, works by introducing an additional RL agent, Shaper, that adaptively learns to construct shaping rewards by observing Controller (the agent whose goal is to solve the environment task) while Controller learns to solve its task. This generates tailored shaping rewards without the need for domain knowledge or manual engineering. The shaping rewards supplement the environment reward and promote effective learning, our framework therefore addresses the key challenges in RS.\nThe resulting framework is a two-player nonzero-sum Markov game (MG) -an extension of Markov decision process (MDP) that involves two independent learners with distinct objectives. In our framework, the two agents that have distinct learning agendas, cooperate to achieve Controller's objective. This MG formulation confers various advantages:\n1) The shaping-reward function is constructed fully autonomously. The game also ensures the shaping reward improves Controller's performance unlike RS methods that can lower performance.\n2) By learning the shaping-reward function while Controller learns its optimal policy, Shaper learns to adaptively facilitate Controller's learning and improve Controller's performance.\n3) Both learning processes converge so Controller learns the optimal value function for its task. 4) ROSA learns subgoals to decompose complex tasks and promote complex exploration patterns.\nAn integral component of ROSA is a novel combination of RL and switching controls. This enables Controller to quickly determine useful states to learn to add and calibrate shaping rewards (i.e. the states in which adding shaping rewards improve Controller's performance) and disregard others. This is in contrast with an RL controller (i.e. Controller) which must learn its best actions at every state. This leads to Shaper quickly finding shaping rewards that guide Controller's learning process toward optimal trajectories (and away from suboptimal trajectories, c.f. Experiment 1).\nFor our two-player framework to succeed we have to overcome several obstacles. Solving MGs involves finding a stable point in which each player responds optimally to the actions of the other. In our MG, this stable point describes a pair of policies for which Shaper introduces a shaping reward that improves performance and, with that, Controller executes an optimal policy for the task. Tractable methods for solving MGs are rare with convergence of MG methods being seldom guaranteed except in a few special cases. Nevertheless, using special features in the design of our game, we prove the existence of a stable point solution of our MG. We then prove the convergence of our learning method to the solution of the game and show that the solution coincides with the solution of the Controller's problem. This ensures Shaper learns a shaping-reward function that improves Controller's performance and that Controller learns the optimal value function for the task.\nThe resulting framework is a two-player nonzero-sum Markov game (MG) [34] – an extension of Markov decision process (MDP) that involves two independent learners with distinct objectives. In our framework, the two agents that have distinct learning agendas, cooperate to achieve Controller’s objective. 1) The shaping-reward function is constructed fully autonomously. The game also ensures the shaping reward improves Controller’s performance unlike RS methods that can lower performance. 2) By learning the shaping-reward function while Controller learns its optimal policy, Shaper learns to adaptively facilitate Controller’s learning and improve Controller’s performance. 3) Both learning processes converge so Controller learns the optimal value function for its task. 4) ROSA learns subgoals [28] to decompose complex tasks and promote complex exploration patterns.",

Replicating this feat with computational tools has been the focus of much research in clinical informatics. There are major initiatives underway to codify clinical knowledge into formal representations, most often as deterministic rules that can be applied in a semi-automated fashion BIBREF0 . However, representing the intuitive judgments of human experts can be challenging, particularly when the formal system does not match the expert's knowledge. For example, many deterministic disease classifiers used in clinical informatics rely heavily upon administrative codes not available at time of diagnosis. Further, developing and testing such systems is time- and labor-intensive.\nWe propose instead a lightweight information theoretic framework for codifying informal human knowledge and then use it to extract interpretable latent topics from text corpora. For example, to discover patients with diabetes in a set of clinical notes, a doctor can begin by specifying disease-specific anchor terms BIBREF1 , BIBREF2 , such as “diabetes” or “insulin.” Our framework then uses these to help discover both latent topics associated with diabetes and records in which diabetes-related topics occur. The user can then add (or remove) additional anchor terms (e.g., “metformin”) to improve the quality of the learned (diabetes) topics.\nIn this workshop paper, we introduce a simple approach to anchored information theoretic topic modeling using a novel combination of Correlation Explanation (CorEx) BIBREF3 and the information bottleneck BIBREF4 . This flexible framework enables the user to leverage domain knowledge to guide exploration of a collection of documents and to impose semantics onto latent factors learned by CorEx. We present preliminary experimental results on two text corpora (including a corpus of clinical notes), showing that anchors can be used to discover topics that are more specific and relevant. What is more, we demonstrate the potential for this framework to perform weakly supervised learning in settings where labeling documents is prohibitively expensive BIBREF5 , BIBREF6 .\nWith respect to interpretable machine learning, our contributions are twofold. First, our framework provides a way for human users to share domain knowledge with a statistical learning algorithm that is both convenient for the human user and easily digestible by the machine. Second, our experimental results confirm that the introduction of simple anchor words can improve the coherence and human interpretability of topics discovered from data. Both are essential to successful and interactive collaboration between machine learning and human users.\nWe present preliminary experimental results on two text corpora (including a corpus of clinical notes), showing that anchors can be used to discover topics that are more specific and relevant.",

        "answer": "Since VAE trains the model based on sampling, we hypothesized that the uncertainty in the classification process through the location in the latent space may increase by repeating the sampling process. Therefore, we tried to make the latent space as suitable for classification with VAE properties as possible. As a result, MNIST and FashionMNIST showed a 1% performance improvement. The motivation for using this uncertainty layer is briefly mentioned in Appendix A.5.\nWhile applying the uncertainty layer, the configuration of the latent space is well clustered by class so that it is more suitable for classification, shown in Figure 10 of the Appendix. If you look at the part where the uncertainty layer is not used in Figure 10 (b), you can see that the pink cluster and the surrounding cluster are a little bit mixed. On the other hand, if you look at the part where the uncertainty layer is used in Figure 10 (b), you can see that each cluster is neatly disentangled. Since the locations of the prototypes are determined for accurate classification in this latent space, the prototypes are positioned at a certain point that is better formed when the uncertainty layer is used as shown in Figure 11. This part was inspired by [1] to create certain data by shifting uncertain data from the latent space of VAE in a direction to reduce uncertainty.\nWe aim to reduce the uncertainty of the classification process to make the configuration of the latent space and the location of the prototype more suitable for classification. Therefore, we think that the uncertainty layer can show advantages in other complex datasets. It seems that this was not well expressed in the paper, so we will mention the motivation in section 3.3 Using uncertainty.",

Obviously, such analysis is time-consuming and possibly biased and it cannot be applied to the enormous amount of news that flood social media and the Internet. Research on detecting propaganda has focused primarily on classifying entire articles as propagandistic/non-propagandistic BIBREF0, BIBREF1, BIBREF2. Such learning systems are trained using gold labels obtained by transferring the label of the media source, as per Media Bias/Fact Check judgment, to each of its articles. Such distant supervision setting inevitably introduces noise in the learning process BIBREF3 and the resulting systems tend to lack explainability.\nWe argue that in order to study propaganda in a sound and reliable way, we need to rely on high-quality trusted professional annotations and it is best to do so at the fragment level, targeting specific techniques rather than using a label for an entire document or an entire news outlet. Therefore, we propose a novel task: identifying specific instances of propaganda techniques used within an article.

As shown in Figure 14 in Appendix, the average value of the spike is about 7.1 for instance incremental sequence, 7.2 for random class incremental sequence, and 7.6 for distant class incremental sequence. See Appendix B.5 for more details on the pre-training loss.",
        "evidence": "Figure 14 shows the self-supervised training loss at each step in sequential training for various types of streaming data. The loss curves illustrate the average MoCo-v2 training loss for each data chunk, i.e., the contrastive loss. We have two observations. First, given a type of streaming data like the instance incremental sequence, in the sequential training process, the training loss would spike when moving to a new disjoint data chunk. Second, the loss spike value becomes higher with increasing distribution shifts, e.g., training loss increases from instance incremental learning (7.1), random class incremental learning (7.2), to distant class incremental learning (7.4) at the beginning of step 2. The queue size is 65,536 for MoCo-v2, and the training batch size is 256. We record the training loss value averaged across one training batch and plot the loss data point every 250 training iterations, which means that after the first point in the loss curve, we have a filled queue for contrastive learning. Therefore, the loss spike is not because of the training mechanism, such as the queue’s refreshing in early training iterations. Instead, it is reasonable to ascribe the loss spike to the distribution shift change of training data, i.e., the new chunk. As for the first chunk, the initial average contrastive loss is significant (around 10) because we randomly initialize the representation model. As for subsequent chunks, we inherit the representation model from the previous step. Therefore the initial average contrastive loss is not significant, i.e., around 7.2. On each chunk, we train the model for 200 epochs and finally observe the convergence of contrastive loss. We find that the average contrastive loss would generally converge to the value of around 6.6 for all chunks. We adopt the same training mechanism for each chunk, including the difficulty of the instance discrimination task and hyperparameter settings. We perform contrastive learning until convergence on each chunk. As a result, the final loss value is similar for different chunks across different settings.",

It was released on 11 February 1991 as the second single from the band's first album, Blue Lines (1991), on the band's Wild Bunch label distributed by Circa Records. The name \"Massive\" was used to avoid a radio ban, as the track's release coincided with the Gulf War.

        "evidence": "Electroencephalography (EEG) is a non invasive way of measuring electrical activity of human brain. In BIBREF0 we demonstrated deep learning based automatic speech recognition (ASR) using EEG signals for a limited English vocabulary of four words and five vowels. In this paper we extend our work for a much larger English vocabulary and we use state-of-art end-to-end continuous speech recognition models to perform recognition. In our prior work we predicted isolated words and vowels.\nASR systems forms the front end or back end in many cutting edge voice activated technologies like Amazon Alexa, Apple Siri, Windows Cortana, Samsung Bixby etc. Unfortunately these systems are trained to recognize text only from acoustic features. This limits technology accessibility to people with speaking disabilities and disorders. The research work presented in this paper tries to address this issue by investigating speech recognition using only EEG signals with no acoustic input and also by combining EEG features along with traditional acoustic features to perform recognition. We believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.\nASR performance is degraded in presence of noisy speech and in real life situations most of the speech is noisy. Inspired from the unique robustness to environmental artifacts exhibited by the human auditory cortex BIBREF1 , BIBREF2 we used very noisy speech data for this work and demonstrated lower word error rate (WER) for smaller corpus using EEG features, concatenation of EEG features and acoustic features.\nIn BIBREF3 authors decode imagined speech from EEG using synthetic EEG data and connectionist temporal classification (CTC) network but in our work we use real EEG data, use EEG data recorded along with acoustics. In BIBREF4 authors perform envisioned speech recognition using random forest classifier but in our case we use end to end state of art models and perform recognition for noisy speech. In BIBREF5 authors demonstrate speech recognition using electrocorticography (ECoG) signals, which are invasive in nature but in our work we use non invasive EEG signals.\nThis work is mainly motivated by the results explained in BIBREF0 , BIBREF6 , BIBREF7 , BIBREF3 . In BIBREF6 the authors used classification approach for identifying phonological categories in imagined and silent speech but in our work we used continuous speech recognition state of art models and our models were predicting words, characters at each time step. Similarly in BIBREF7 neural network based classification approach was used for predicting phonemes.\nMajor contribution of this paper is the demonstration of end to end continuous noisy speech recognition using only EEG features and this paper further validates the concepts introduced in BIBREF0 for a much larger English corpus.\nThe research work presented in this paper tries to address this issue by investigating speech recognition using only EEG signals with no acoustic input and also by combining EEG features along with traditional acoustic features to perform recognition.",

        "evidence": "The geological record reveals that \"great earthquakes\" (those with moment magnitude 8 or higher) occur in the Cascadia subduction zone about every 500 years on average, often accompanied by tsunamis. There is evidence of at least 13 events at intervals from about 300 to 900 years with an average of 570–590 years. Previous earthquakes are estimated to have been in AD 1310, AD 810, AD 400, 170 BC and 600 BC.[citation needed]\n\nCascadia earthquake sources\n\nAs seen in the 1700 quake, the 2004 Indian Ocean earthquake, and the 2011 Tōhoku earthquake and tsunami, subduction zone earthquakes can cause large tsunamis, and many coastal areas in the region have prepared tsunami evacuation plans in anticipation of a possible future Cascadia earthquake. However, the major nearby cities, notably Seattle, Portland, Vancouver, Victoria, and Tacoma, which are located on inland waterways rather than on the coast, would be sheltered from the full brunt of a tsunami. These cities do have many vulnerable structures, especially bridges and unreinforced brick buildings; consequently, most of the damage to the cities would probably be from the earthquake itself. One expert asserts that buildings in Seattle are vastly inadequate even to withstand an event of the size of the 1906 San Francisco earthquake, let alone any more powerful one.\n\nKenneth Murphy, who directs FEMA's Region X, the division responsible for Oregon, Washington, Idaho, and Alaska, put it quite dramatically: \"Our operating assumption is that everything west of Interstate 5 will be toast.\"\n\nRecent findings conclude that the Cascadia subduction zone is more complex and volatile than previously believed. In 2010, geologists predicted a 37% chance of an M8.2+ event within 50 years, and a 10 to 15% chance that the entire Cascadia subduction zone will rupture with an M9+ event within the same time frame. Geologists have also determined the Pacific Northwest is not prepared for such a colossal quake. The tsunami produced could reach heights of 80 to 100 feet (24 to 30 m).\n\nA 2004 study revealed the potential for relative mean sea level rise (caused by subsidence) along the Cascadia subduction zone.

Grapes ripen early on sandy, silty loam soils. The elevation ranges from 220 to 370 metres (720 to 1,210 ft).\nBendigo lies east of the Clutha River / Mata-Au and Lake Dunstan, with grapes planted at both medium elevation (220 metres (720 ft)) and high elevation terraces (330 to 350 metres (1,080 to 1,150 ft)). This warm area has semi arid soils at variable depths, with free draining soils at the lower levels and shallower soils at higher elevations. The Bendigo sub-region includes the vineyards at Tarras and Maori Point.\nGibbston is a tight valley enclosed by mountainous terrain. About 250 hectares of vines are planted on sloping land on the southern bank of the Kawarau River. Gibbston is the coolest and highest of the sub-regions with vineyards between 320 and 420 metres (1,050 and 1,380 ft) altitude. It is sometimes referred to as the Queenstown subregion.\nWānaka, the smallest of the sub-regions, has vineyards planted between the banks of Lake Wānaka and the town of Luggate to the east. Ranging between 290 to 320 metres (950 to 1,050 ft) above sea level, the vineyards have a similar but slightly warmer climate than those at Gibbston.\nThe Alexandra Basin is surrounded by the Clutha River / Mata-Au and Manuherikia River and regularly records New Zealand's hottest summer temperatures. Schist outcrops dominate the arid landscape. A wide diurnal shift moderates the high temperatures.\nThe Cromwell Basin contains the highest concentration of vines, in an area bounded by the Kawarau River, Lake Dunstan and the Pisa mountain range. It is a warm district characterised by semi arid, high terraces and moraines and gently sloping fans.\"",

        "question": "Are they the first to show that the learning rate warm-up stage can be removed for the Pre-LN Transformer?",
        "answer": "Yes.",
        "evidence": "The Transformer BIBREF0 is one of the most commonly used neural network architectures in natural language processing. Layer normalization BIBREF1 plays a key role in Transformer's success. The originally designed Transformer places the layer normalization between the residual blocks, which is usually referred to as the Transformer with Post-Layer Normalization (Post-LN) BIBREF2. This architecture has achieved state-of-the-art performance in many tasks including language modeling BIBREF3, BIBREF4 and machine translation BIBREF5, BIBREF6. Unsupervised pre-trained models based on the Post-LN Transformer architecture also show impressive performance in many downstream tasks BIBREF7, BIBREF8, BIBREF9.\nDespite its great success, people usually need to deal with the optimization of the Post-LN Transformer more carefully than convolutional networks or other sequence-to-sequence models BIBREF10. In particular, to train the model from scratch, any gradient-based optimization approach requires a learning rate warm-up stage BIBREF0, BIBREF11: the optimization starts with an extremely small learning rate, and then gradually increases it to a pre-defined maximum value in a pre-defined number of iterations. Such a warm-up stage not only slows down the optimization process but also brings more hyperparameter tunings. BIBREF10 has shown that the final model performance is quite sensitive to the value of the maximum learning rate and the number of warm-up iterations. Tuning such sensitive hyper-parameters is costly in training large-scale models, e.g., BERT BIBREF8 or XLNet BIBREF9.\nIn this paper, we try to alleviate this problem by finding ways to safely remove the learning rate warm-up stage. As the warm-up stage happens in the first several iterations, we investigate the optimization behavior at initialization using mean field theory BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. According to our theoretical analysis, when putting the layer normalization between the residual blocks, the expected gradients of the parameters near the output layer are large. Therefore, without the warm-up stage, directly using a large learning rate to those parameters can make the optimization process unstable. Using a warm-up stage and training the model with small learning rates practically avoid this problem. Extensive experiments are provided to support our theoretical findings.\nOur theory also shows that the layer normalization plays a crucial role in controlling the gradient scales. This motivates us to investigate whether there are some other ways of positioning the layer normalization that lead to well-behaved gradients. In particular, we study another variant, the Transformer with Pre-Layer Normalization (Pre-LN) BIBREF18, BIBREF19, BIBREF2. The Pre-LN Transformer puts the layer normalization inside the residual connection and equips with an additional final-layer normalization before prediction (Please see Figure SECREF1 for the differences between the two variants of the Transformer architectures). We show that at initialization, the gradients are well-behaved without any exploding or vanishing for the Pre-LN Transformer both theoretically and empirically.\nGiven the gradients are well-behaved in the Pre-LN Transformer, it is natural to consider removing the learning rate warm-up stage during training. We conduct a variety of experiments, including IWSLT14 German-English translation, WMT14 English-German translation, and BERT pre-training tasks. We show that, in all tasks, the learning rate warm-up stage can be safely removed, and thus, the number of hyper-parameter is reduced. Furthermore, we observe that the loss decays faster for the Pre-LN Transformer model. It can achieve comparable final performances but use much less training time. This is particularly important for training large-scale models on large-scale datasets.\nOur contributions are summarized as follows:\n$\\bullet $ We investigate two Transformer variants, the Post-LN Transformer and the Pre-LN Transformer, using mean field theory. By studying the gradients at initialization, we provide evidence to show why the learning rate warm-up stage is essential in training the Post-LN Transformer.\n$\\bullet $ We are the first to show that the learning-rate warm-up stage can be removed for the Pre-LN Transformer, which eases the hyperparameter tuning. We further show that by using proper learning rate schedulers, the training time can be largely reduced on a wide range of applications.\nWe are the first to show that the learning-rate warm-up stage can be removed for the Pre-LN Transformer, which eases the hyperparameter tuning.

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;",

The data warehouse bus architecture is primarily an implementation of \"the bus\", a collection of conformed dimensions and conformed facts, which are dimensions that are shared (in a specific way) between facts in two or more data marts.\n\nTop-down design\nThe top-down approach is designed using a normalized enterprise data model. \"Atomic\" data, that is, data at the greatest level of detail, are stored in the data warehouse. Dimensional data marts containing data needed for specific business processes or specific departments are created from the data warehouse.\n\nHybrid design\nData warehouses (DW) often resemble the hub and spokes architecture. Legacy systems feeding the warehouse often include customer relationship management and enterprise resource planning, generating large amounts of data. To consolidate these various data models, and facilitate the extract transform load process, data warehouses often make use of an operational data store, the information from which is parsed into the actual DW. To reduce data redundancy, larger systems often store the data in a normalized way. Data marts for specific reports can then be built on top of the data warehouse.\n\nA hybrid DW database is kept on third normal form to eliminate data redundancy. A normal relational database, however, is not efficient for business intelligence reports where dimensional modeling is prevalent. Small data marts can shop for data from the consolidated warehouse and use the filtered, specific data for the fact tables and dimensions required. The DW provides a single source of information from which the data marts can read, providing a wide range of business information. The hybrid architecture allows a DW to be replaced with a master data management repository where operational (not static) information could reside.\n\nThe data vault modeling components follow hub and spokes architecture.

        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

Grounded VQG generates visually grounded questions, i.e., all relevant information for the answer can be found in the input image BIBREF74 . A key purpose of grounded VQG is to support the dataset construction for VQA. To ensure the questions are grounded, existing systems rely on image captions to varying degrees. BIBREF75 and BIBREF76 simply convert image captions into questions using rule-based methods with textual patterns. BIBREF74 proposed a neural model that can generate questions with diverse types for a single image, using separate networks to construct dense image captions and to select question types.\nIn contrast to grounded QG, humans ask higher cognitive level questions about what can be inferred rather than what can be seen from an image. Motivated by this, BIBREF10 proposed open-ended VQG that aims to generate natural and engaging questions about an image. These are deep questions that require high cognition such as analyzing and creation. With significant progress in deep generative models, marked by variational auto-encoders (VAEs) and GANs, such models are also used in open-ended VQG to bring “creativity” into generated questions BIBREF77 , BIBREF78 , showing promising results.

For example, while the care takers are eating a meal, allowing the child (at any age) to pick food from the care taker's plate. There is the thought is that the human body will self regulate what it needs instinctively.   The notion of self regulation applies to nutrients found in the food as well as the amount of food that the body need.  The mainstream alternative (especially in first world countries) is pureed foods prepared especially for babies. Those that subscribe to BLW believe that the downside of feeding babies baby specific food is that the practice teaches babies to ignore natural instincts because someone else is in control of what type and how much food to eat.  Some reasons people choose not to follow BLW are: the misconception that babies cannot eat solid food,  the convenience of prepared commercial baby food, generally accepted mainstream guidance on baby rearing, or the lack of awareness of BLW. BLW can also be quite messy as some of the food babies will handle are a function of exploration rather than for consumption and therefore end up on the floor.",

        "evidence": "Reasoning is part of our every day routine: we hear Natural Language (NL) sentences, we participate in dialogues, we read books or legal documents. Successfully understanding, participating or communicating with others in these situations presupposes some form of reasoning: about individual sentences, whole paragraphs of legal documents, small or bigger pieces of dialogue and so on. The human reasoning performed in these different situations cannot be explained by a single rigid system of reasoning, plainly because reasoning is performed in different ways in each one of them. Consider the following example:\nThree representatives are needed.\nIf a human reasoner with expert knowledge was to interpret the above utterance in a legal context, s/he will most probably judge that a situation where more than three references are provided could be compatible with the semantics of the utterance. To the contrary, if the same reasoner was to interpret the above as part of a casual, everyday conversation, then three would most likely be interpreted as exactly three, making the same situation incompatible with the utterance. In this paper, we want to focus on precise inference, inference which is either performed by experts or normal people after taking some time to consider the inferences that follow or not from a set of premises. The problem one encounters in testing systems of this type of reasoning is the fact that no large scale datasets of this sort of inference exist. The commonly used datasets for systems fit for this type of precise reasoning, i.e. logical systems based on some model of formal semantics for Natural Language (NL), are the FraCaS test suite and the Recognizing Textual Entailment (RTE) datasets.\nIn this paper, we want to focus on precise inference, inference which is either performed by experts or normal people after taking some time to consider the inferences that follow or not from a set of premises.",

First, to make the model's prediction more explainable, we implement a path based QA model PCNet. In this model, to get candidate answers from the triplets based document for a given question. We first retrieve the an “anchor” point $arg1_i$ or $arg2_i$ in the document fact $f_i$ . These anchors are selected based on edit distance between the words in the questions and the arguments. Then we regard all arguments in the 1-hops and 2-hops fact of the anchors as answers. However, the coverage of the candidate answers can be 100% in the model. We then implement a second end-to-end neural model KVMenNet which covers all the answers but with less interpretability. Both models generate a score $f_{qa}(q, a)$ of each candidate answer.\nWe then implement a generation-based model. The motivation to design this model is that we want to associate natural language phrases with knowledge based representation. It takes semantics of a candidate answer as the input and generates a question $\\hat{q}$ . Then a paraphrasing model gives a score $f_{qg}(q,\\hat{q})$ , which is computed between the generated question $\\hat{q}$ and the original question $q$ , as the ranking score.\nWe get the final scores $S(q,a)$ used for ranking as follows. \n$$S(q,a) = \\lambda f_{qa}(q, a) + (1-\\lambda ) f_{qg}(q,\\hat{q})$$   (Eq. 7) \nMoreover, we incorporate side information from external KBs into the three models. The details of how we use external KBs to enhance the representation of elements in the document KB will be described in section Incorporating External Knowledge.\nOur framework consists of a question answering model and a question generation model.",

The platforms for creating chatbots mainly provide tools for adding and training intentions together with dialogue flow specification and some entities extraction, with no reasoning support. Once the models are trained and the dialogue flow specified, the chatbots are able to reply to the received intention. The platforms for creating service chatbots provide the same functionalities as the last one and also provide support for defining actions to be executed by the chatbots when they are answering to an utterance.

Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole.\n\nThe modern study of set theory was initiated by the German mathematicians Richard Dedekind and Georg Cantor in the 1870s. In particular, Georg Cantor is commonly considered the founder of set theory. The non-formalized systems investigated during this early stage go under the name of naive set theory. After the discovery of paradoxes within naive set theory (such as Russell's paradox, Cantor's paradox and the Burali-Forti paradox) various axiomatic systems were proposed in the early twentieth century, of which Zermelo–Fraenkel set theory (with or without the axiom of choice) is still the best-known and most studied.\n\nSet theory is commonly employed as a foundational system for the whole of mathematics, particularly in the form of Zermelo–Fraenkel set theory with the axiom of choice. Besides its foundational role, set theory also provides the framework to develop a mathematical theory of infinity, and has various applications in computer science (such as in the theory of relational algebra), philosophy and formal semantics. Its foundational appeal, together with its paradoxes, its implications for the concept of infinity and its multiple applications, have made set theory an area of major interest for logicians and philosophers of mathematics. Contemporary research into set theory covers a vast array of topics, ranging from the structure of the real number line to the study of the consistency of large cardinals.",

We explore an architecture based on a stack of dilated convolution layers, effectively operating on a broader scale than with standard convolutions while limiting model size.

In BIBREF11 , the authors explore Deep Residual Networks (ResNets) for KWS. ResNets differ from WaveNet models in that they do not leverage skip-connections and gating, and apply convolution kernels in the frequency domain, drastically increasing the computational cost.\nStandard convolutional networks cannot capture long temporal patterns with reasonably small models due to the increase in computational cost yielded by larger receptive fields. Dilated convolutions skip some input values so that the convolution kernel is applied over a larger area than its own. The network therefore operates on a larger scale, without the downside of increasing the number of parameters.

Together with the guideline document, the annotators are educated some tips in fifteen minutes and also provided with 20 exemplifying sentences.\nLabeled Data: DL-PS. In Dialog domain (DL), we collect raw sentences from a chatbot application. And then we randomly select 20K sentences as our pool and hire 43 students to annotate the sentences. We ask the annotators to label two types of entities: Person-Name and Song-Name. The annotators label the sentences independently. In particular, each sentence is assigned to three annotators for this data. Although the setting can be wasteful of labor, we can use the resulting dataset to test several well-known baselines such as majority voting.\nAfter annotation, we remove some illegal sentences reported by the annotators. Finally, we have 16,948 sentences annotated by the students. Table 1 shows the information of annotated data. The average Kappa value among the annotators is 0.6033, indicating that the crowd annotators have moderate agreement on identifying entities on this data.\nIn order to evaluate the system performances, we create a set of corpus with gold annotations. Concretely, we randomly select 1,000 sentences from the final dataset and let two experts generate the gold annotations. Among them, we use 300 sentences as the development set and the remaining 700 as the test set.

Five students participate the annotations for this domain since the number of sentences is small. We use the similar strategy as DL-PS to annotate the sentences, except that only two annotators are assigned for each sentence, because we aim to test the system performances under very small duplicated annotations.\nFinally, we obtain 2,337 sentences for EC-MT and 2,300 for EC-UQ.

        "evidence": "Diagrams are a common feature of many everyday media from newspapers to school textbooks, and not surprisingly, different forms of diagrammatic representation have been studied from various perspectives. To name just a few examples, recent work has examined patterns in diagram design BIBREF0 and their interpretation in context BIBREF1, and developed frameworks for classifying diagrams BIBREF2 and proposed guidelines for their design BIBREF3. There is also a long-standing interest in processing and generating diagrams computationally BIBREF4, BIBREF5, BIBREF6, which is now resurfacing as advances emerging from deep learning for computer vision and natural language processing are brought to bear on diagrammatic representations BIBREF7, BIBREF8, BIBREF9.\nFrom the perspective of computational processing, diagrammatic representations present a formidable challenge, as they involve tasks from both computer vision and natural language processing. On the one hand, diagrams have a spatial organisation – layout – which needs to be segmented to identify meaningful units and their position. Making sense of how diagrams exploit the 2D layout space falls arguably within the domain of computer vision. On the other hand, diagrams also have a discourse structure, which uses the layout space to set up discourse relations between instances of natural language, various types of images, arrows and lines, thus forming a unified discourse organisation. The need to parse this discourse structure shifts the focus towards the field of natural language processing.\nUnderstanding and making inferences about the structure of diagrams and other forms of multimodal discourse may be broadly conceptualised as multimodal discourse parsing. Recent examples of work in this area include alikhanietal2019 and ottoetal2019, who model discourse relations between natural language and photographic images, drawing on linguistic theories of coherence and text–image relations, respectively. In most cases, however, predicting a single discourse relation covers only a part of the discourse structure. sachanetal2019 note that there is a need for comprehensive theories and models of multimodal communication, as they can be used to rethink tasks that have been previously considered only from the perspective of natural language processing.\nUnlike many other areas, the study of diagrammatic representations is particularly well-resourced, as several multimodal resources have been published recently to support research on computational processing of diagrams BIBREF10, BIBREF8, BIBREF11. This study compares two such resources, AI2D BIBREF10 and AI2D-RST BIBREF11, which both feature the same diagrams, as the latter is an extension of the former. Whereas AI2D features crowd-sourced, non-expert annotations, AI2D-RST provides multiple layers of expert annotations, which are informed by state-of-the-art approaches to multimodal communication BIBREF12 and annotation BIBREF13, BIBREF14.\nThis provides an interesting setting for comparison and evaluation, as non-expert annotations are cheap to produce and easily outnumber the expert-annotated data, whose production consumes both time and resources. Expert annotations, however, incorporate domain knowledge from multimodality theory, which is unavailable via crowd-sourcing. Whether expert annotations provide better representations of diagrammatic structures and thus justify their higher cost is one question that this study seeks to answer.\nBoth AI2D and AI2D-RST represent the multimodal structure of diagrams using graphs. This enables learning their representations using graph neural networks, which are gaining currency as a graph is a natural choice for representing many types of data BIBREF15. This article reports on two experiments that evaluate the capability of AI2D and AI2D-RST to represent the multimodal structure of diagrams using graphs, focusing particularly on spatial layout, the hierarchical organisation of diagram elements and their connections expressed using arrows and lines.\nThis article reports on two experiments that evaluate the capability of AI2D and AI2D-RST to represent the multimodal structure of diagrams using graphs, focusing particularly on spatial layout, the hierarchical organisation of diagram elements and their connections expressed using arrows and lines.",

Contrary to a traditional centralized security team model, each delivery team is empowered to factor in the correct security controls into their software delivery. Security practices and testing are performed earlier in the development lifecycle, hence the term \"shift left\" can be used. Security is tested in three main areas: static, software composition, and dynamic.\n\nChecking the code statically via static application security testing (SAST) is white-box testing with special focus on security. Depending on the programming language, different tools are needed to do such static code analysis. The software composition is analyzed, especially libraries and their versions are checked against vulnerability lists published by CERT and other expert groups. When giving software to clients, licenses and its match to the one of the software distributed are in focus, especially copyleft licenses. Dynamic testing is also called black-box testing. The software is tested without knowing its inner functions. In DevSecOps it is on one hand called dynamically (DAST), or penetration testing. The goal is to catch, amongst others, errors like cross-site scripting, or SQL injection early. Threat types are for example published by the open web application security project, e.g. its TOP10.

        "evidence": "Our system was designed to cluster documents from a (potentially infinite) real-word data stream. The datasets typically used in the literature (TDT, Reuters) have a small number of clusters ( INLINEFORM0 20) with coarse topics (economy, society, etc.), and therefore are not relevant to the use case of media monitoring we treat - as it requires much more fine-grained story clusters about particular events. To evaluate our approach, we adapted a dataset constructed for the different purpose of binary classification of joining cluster pairs. We processed it to become a collection of articles annotated with monolingual and crosslingual cluster labels.\nStatistics about this dataset are given in Table TABREF30 . As described further, we tune the hyper-parameter INLINEFORM0 on the development set. As for the hyper-parameters related to the timestamp features, we fixed INLINEFORM1 and tuned INLINEFORM2 on the development set, yielding INLINEFORM3 .

The discussion in Section 7.3 aimed to show that there are mainly two different ways to locally measure different levels/aspects of theory of mind in specific setups, that both could be useful to measure particular phenomena, but none generalize to a global metric as well as using the reward.",
        "evidence": "In this section, we compare the different algorithms explained in the previous section. The observation space will be constituted of a processed version of the last turn in the episode, to keep the input size controlled. More precisely, the observation space is composed of: the position of all agents, all recharge bases, the current direction each agent is moving towards to and what they communicated in the last turn, the presence of a wall in each of the immediate surroundings, and every agents' first-hand information. First-hand information is publicly available in our experiments to moderate the difficulty of the setup, but this constraint could also be removed. This simple setting is still partially observable, since the agents cannot hear interactions outside of their hearing range.\nWe use the reward as our main evaluation metric. This metric indirectly evaluates ToM capabilities, since information-seeking is at the core of SymmToM. We train through 60000 episodes, and with 7 random seeds to account for high variances in the rewards obtained. Our policies are parametrized by a two-layer ReLU MLP with 64 units per layer, as in the original MADDPG. MADDPG-EE's function f is also a two-layer ReLU MLP with 64 units per layer.\nWe test two board sizes (w = 6, and w = 12), two numbers of agents (a = 3 and a = 4), and three quantities of information pieces (c = a, c = 2a c = 3a). The length of each episode is set to 5w.\nMore detail about design decisions can be found in Section A.5.\nIn the past section we analyzed results using the metric of episode rewards. Although the rewards in SymmToM are designed to correlate with information seeking and knowledge state of the agent themselves and others, they do not show explicitly if agents are exhibiting theory of mind. To do so more directly, we develop two categories of possible analyses: scenarios specifically designed to test theory of mind, and post-hoc analyses of episodes.\nA classic example of a scenario specifically designed to test ToM behavior is the Sally-Anne task. This false belief task, originally designed for children, aims to test if a passive observer can answer questions about the beliefs of another person, in situations where that belief may not match reality. If we were to use it for machine ToM, we could repeat the experiment and ask an agent to predict the position of an object varying the underlying conditions. This test is feasible because there is only one agent with freedom of action, which ensures that desired conditions are met every time. Testing becomes unfeasible when giving multiple agents freedom of action, as constraints planned in test design may be broken by a collective drift from the strategy thought by the designer. Testing becomes easier if we allow for controlling all agents but one, as shown in Fig.. Other tests besides the ones shown may be designed. In particular, in Fig. we show an example of probabilistic ToM where two communicative events are equally likely, but one could modify this scenario to have different probabilities and test the expected value of the turns until red successfully shares an information piece. One could also design retroactive deduction tests: for example, in Fig. if red communicates and receives no reward, it can deduce that green had Figure: Example of tests for zeroth, first, second order, and probabilistic ToM. We test red agents, immobilize gray agents, and control blue and green agents' movements. In Fig., red will go to the top right if it remembers to have heard the first piece, and to the left otherwise. In Fig., red will move to the right if and only if it assumes that the two agents on the left played optimally (red cannot hear what they communicated). In Fig., blue is controlled to ensure it will search the agent on the bottom left (its optimal play, in five moves). Red's optimal move is to meet blue, and hence must only move to the bottom left, even if the agent currently there will not provide any reward. In Fig., red will interact with green not knowing what it communicated with blue in the previous turn. It should be able to communicate the missing piece with an expected value of 1.5 turns. received that information from blue. If there had been another agent (let's say, a yellow agent) in range of blue when it spoke to green, the red agent could also update its knowledge about yellow. Results for the tests proposed in Figure are detailed in Appendix A.1.\nPost-hoc analysis also has its challenges in multi-agent settings, even in the most direct cases. Thanks to our reward shaping, using recharge bases is always the optimal move when an agent has all the information available: an agent will have a reward of (n − 1)c for using the base, whereas it can only gain up to n − 1 + c − 1 per turn if it decides not to use it. Even in this case, small delays in using the base may occur, for example if the agent can gather additional rewards on its path to the base. More generally, having multiple agents makes a specific behaviors attributable to any of the several events happening at once, or a combination of them.\nEven though it may be difficult to establish causality when observing single episodes, we developed metrics that comparatively show which models are using specific features of the environment better than others. Examples of metrics are unsuccessful recharge base usage count; number of times an agent shares an information piece everyone in its range already knows when having better alternatives; number of times an agent moves away from every agent when not having all the information pieces available; among others.

Similarly, for the French and English pair, but when we train on French they are quite lower. We have a similar case when we train on Arabic and test on English. We can justify that by, the language presentation of the Arabic and French tweets are quite informal and have many dialect words that may not exist in the pretrained embeddings we used comparing to the English ones (lower embeddings coverage ratio), which become harder for the CNN to learn a clear semantic pattern. Another point is the presence of Arabic dialects, where some dialect words may not exist in the multilingual pretrained embedding model that we used. On the other hand, from the text-based perspective, the results show that the text-based features can help in the case when the semantic aspect shows weak detection; this is the case for the $Ar\\longrightarrow En$ configuration. It is worthy to mention that the highest result we get in this experiment is from the En$\\rightarrow $Fr pair, as both languages use Latin characters.

Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways; the band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionised many aspects of the music industry and were often publicised as leaders of the era's youth and sociocultural movements.",
        "answer": "ed by primary songwriters Lennon and McCartney, the Beatles evolved from Lennon's previous group, the Quarrymen, and built their reputation playing clubs in Liverpool and Hamburg over three years from 1960, initially with Stuart Sutcliffe playing bass. The core trio of Lennon, McCartney and Harrison, together since 1958, went through a succession of drummers, including Pete Best, before asking Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act, and producer George Martin guided and developed their recordings, greatly expanding their domestic success after signing to EMI Records and achieving their first hit, \"Love Me Do\", in late 1962. As their popularity grew into the intense fan frenzy dubbed \"Beatlemania\", the band acquired the nickname \"the Fab Four\", with Epstein, Martin or another member of the band's entourage sometimes informally referred to as a \"fifth Beatle\".\n\nBy early 1964, the Beatles were international stars and had achieved unprecedented levels of critical and commercial success. They became a leading force in Britain's cultural resurgence, ushering in the British Invasion of the United States pop market, and soon made their film debut with A Hard Day's Night (1964). A growing desire to refine their studio efforts, coupled with the untenable nature of their concert tours, led to the band's retirement from live performances in 1966. At this time, they produced records of greater sophistication, including the albums Rubber Soul (1965), Revolver (1966) and Sgt. Pepper's Lonely Hearts Club Band (1967), and enjoyed further commercial success with The Beatles (also known as \"the White Album\", 1968) and Abbey Road (1969). The success of these records heralded the album era, as albums became the dominant form of record consumption over singles; they also increased public interest in psychedelic drugs and Eastern spirituality, and furthered advancements in electronic music, album art and music videos. In 1968, they founded Apple Corps, a multi-armed multimedia corporation that continues to oversee projects related to the band's legacy. After the group's break-up in 1970, all principal former members enjoyed success as solo artists and some partial reunions have occurred. Lennon was murdered in 1980 and Harrison died of lung cancer in 2001. McCartney and Starr remain musically active.\n\nThe Beatles are the best-selling music act of all time, with estimated sales of 600 million units worldwide. They are the most successful act in the history of the US Billboard charts. They hold the record for most number-one albums on the UK Albums Chart (15), most number-one hits on the US Billboard Hot 100 chart (20), and most singles sold in the UK (21.9 million). The band received many accolades, including seven Grammy Awards, four Brit Awards, an Academy Award (for Best Original Song Score for the 1970 documentary film Let It Be) and fifteen Ivor Novello Awards. They were inducted into the Rock and Roll Hall of Fame in 1988, and each principal member was inducted individually between 1994 and 2015.

        "evidence": "Knowledge Base Question Answering (KBQA) systems answer questions by obtaining information from KB tuples BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 . For an input question, these systems typically generate a KB query, which can be executed to retrieve the answers from a KB. Figure 1 illustrates the process used to parse two sample questions in a KBQA system: (a) a single-relation question, which can be answered with a single $<$ head-entity, relation, tail-entity $>$ KB tuple BIBREF6 , BIBREF7 , BIBREF2 ; and (b) a more complex case, where some constraints need to be handled for multiple entities in the question. The KBQA system in the figure performs two key tasks: (1) entity linking, which links $n$ -grams in questions to KB entities, and (2) relation detection, which identifies the KB relation(s) a question refers to.\nThe main focus of this work is to improve the relation detection subtask and further explore how it can contribute to the KBQA system. Although general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection. First, in most general relation detection tasks, the number of target relations is limited, normally smaller than 100. In contrast, in KBQA even a small KB, like Freebase2M BIBREF2 , contains more than 6,000 relation types. Second, relation detection for KBQA often becomes a zero-shot learning task, since some test instances may have unseen relations in the training data. For example, the SimpleQuestions BIBREF2 data set has 14% of the golden test relations not observed in golden training tuples. Third, as shown in Figure 1 (b), for some KBQA tasks like WebQuestions BIBREF0 , we need to predict a chain of relations instead of a single relation. This increases the number of target relation types and the sizes of candidate relation pools, further increasing the difficulty of KB relation detection. Owing to these reasons, KB relation detection is significantly more challenging compared to general relation detection tasks.\nThis paper improves KB relation detection to cope with the problems mentioned above. First, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching. Second, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations. Third, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information. Finally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching.\nIn order to assess how the proposed improved relation detection could benefit the KBQA end task, we also propose a simple KBQA implementation composed of two-step relation detection. Given an input question and a set of candidate entities retrieved by an entity linker based on the question, our proposed relation detection model plays a key role in the KBQA process: (1) Re-ranking the entity candidates according to whether they connect to high confident relations detected from the raw question text by the relation detection model. This step is important to deal with the ambiguities normally present in entity linking results. (2) Finding the core relation (chains) for each topic entity selection from a much smaller candidate entity set after re-ranking. The above steps are followed by an optional constraint detection step, when the question cannot be answered by single relations (e.g., multiple entities in the question). Finally the highest scored query from the above steps is used to query the KB for answers.\nOur main contributions include: (i) An improved relation detection model by hierarchical matching between questions and relations with residual learning; (ii) We demonstrate that the improved relation detector enables our simple KBQA system to achieve state-of-the-art results on both single-relation and multi-relation KBQA tasks.\nThird, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information.",

        "evidence": "Puerto Rico (Spanish for 'rich port'; abbreviated PR; Taino: Boriken, Borinquen), officially the Commonwealth of Puerto Rico (Spanish: Estado Libre Asociado de Puerto Rico, lit. 'Free Associated State of Puerto Rico'), is a Caribbean island and unincorporated territory of the United States with official Commonwealth status. It is located in the northeast Caribbean Sea, approximately 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic and the U.S. Virgin Islands, and includes the eponymous main island and several smaller islands, such as Mona, Culebra, and Vieques. It has roughly 3.2 million residents, and its capital and most populous city is San Juan. Spanish and English are the official languages of the executive branch of government, though Spanish predominates.\n\nPuerto Rico was settled by a succession of indigenous peoples beginning 2,000 to 4,000 years ago; these included the Ortoiroid, Saladoid, and Taíno. It was then colonized by Spain following the arrival of Christopher Columbus in 1493. Puerto Rico was contested by other European powers, but remained a Spanish possession for the next four centuries. An influx of African slaves and settlers primarily from the Canary Islands and Andalusia vastly changed the cultural and demographic landscape of the island. Within the Spanish Empire, Puerto Rico played a secondary but strategic role compared to wealthier colonies like Peru and New Spain. By the late 19th century, a distinct Puerto Rican identity began to emerge, centered around a fusion of indigenous, African, and European elements. In 1898, following the Spanish–American War, Puerto Rico was acquired by the United States.\n\nPuerto Ricans have been U.S. citizens since 1917, and can move freely between the island and the mainland. However, as residents of an unincorporated territory, American citizens of Puerto Rico are disenfranchised at the national level, do not vote for the president or vice president, and generally do not pay federal income tax.[Note 1] In common with four other territories, Puerto Rico sends a nonvoting representative to the U.S. Congress, called a Resident Commissioner, and participates in presidential primaries; as it is not a state, Puerto Rico does not have a vote in Congress, which governs it under the Puerto Rico Federal Relations Act of 1950. Congress approved a local constitution in 1952, allowing U.S. citizens residing on the island to elect a governor. Puerto Rico's current and future political status has consistently been a matter of significant debate.",

For example, the string `real' is pronounced differently in English, German, Spanish, and Portuguese. We solve this problem by prepending each grapheme sequence with an artificial token consisting of the language's ISO 639-3 code enclosed in angle brackets. The English word `real', for example, would be presented to the system as\n INLINEFORM0 eng INLINEFORM1 r e a l\nThe artificial token is treated simply as an element of the grapheme sequence. This is similar to the approach taken by johnson2016google in their zero-shot NMT system. However, their source-side artificial tokens identify the target language, whereas ours identify the source language. An alternative approach, used by ostling2017continuous, would be to concatenate a language embedding to the input at each time step. They do not evaluate their approach on grapheme-to-phoneme conversion.\nIn order to train a neural g2p system， one needs a large quantity of pronunciation data.

        "evidence": "The Dark Side of the Moon is the eighth studio album by the English rock band Pink Floyd, released on 1 March 1973 by Harvest Records. Developed during live performances before recording began, it was conceived as a concept album that would focus on the pressures faced by the band during their arduous lifestyle, and also deal with the mental health problems of former band member Syd Barrett, who departed the group in 1968. New material was recorded in two sessions in 1972 and 1973 at EMI Studios (now Abbey Road Studios) in London.\n\nThe record builds on ideas explored in Pink Floyd's earlier recordings and performances, while omitting the extended instrumentals that characterised the band's earlier work. The group employed multitrack recording, tape loops, and analogue synthesisers, including experimentation with the EMS VCS 3 and a Synthi A. Engineer Alan Parsons was responsible for many of the sonic aspects of the recording, and for the recruitment of session singer Clare Torry, who appears on \"The Great Gig in the Sky\".\n\nThe Dark Side of the Moon explores themes such as conflict, greed, time, death and mental illness. Snippets from interviews with the band's road crew and others are featured alongside philosophical quotations. The sleeve, which depicts a prismatic spectrum, was designed by Storm Thorgerson in response to keyboardist Richard Wright's request for a \"simple and bold\" design which would represent the band's lighting and the album's themes. The album was promoted with two singles, \"Money\" and \"Us and Them\".\n\nThe Dark Side of the Moon is among the most critically acclaimed albums and often features in professional listings of the greatest albums. It brought Pink Floyd international fame, wealth, and plaudits to all four band members. A blockbuster release of the album era, it also propelled record sales throughout the music industry during the 1970s. The Dark Side of the Moon is certified 14 times platinum in the United Kingdom, and topped the US Billboard Top LPs & Tape chart, where it has charted for 977 weeks. As of 2013, The Dark Side of the Moon has sold over 45 million copies worldwide, making it the best-selling album of the 1970s and the fourth-best-selling album in history.

        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nOur experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.",

        "answer": "There are several, in fact! The most famous example would be the Okavango River, which - instead of reaching the ocean - peters out into the massive Okavango Delta and evaporates, in the middle of the Kalahari Desert. Some other notable instances include the Onyx River - the longest river in Antarctica, at 32 kilometres in length - which simply flows from one lake to another. And the Omo River, which starts in the Ethiopian Highlands and ends in Lake Turkana, Kenya. But these last two flow into lakes. That’s not unusual for a river, right?\nCertainly not; however, in the vast majority of cases, the river’s water will meet the sea eventually, as almost all lakes are drained by other rivers which reach the ocean. Not so for these lakes. Why? Because they’re in what are known as endorheic basins. In hydrology, a basin is a region in which all precipitation will drain and collect into a common outlet. There are innumerable river basins throughout the world, with dozens in the (contiguous) US alone. If you look closely at the US map, you might notice that not all these river basins enter the sea. They are endorheic basins; closed, self-contained systems where the amount of water flowing in is equal to the amount which evaporates or seeps away.\nYou can theoretically find them in any climate, but they tend to be in very dry areas - e.g. the Kalahari - as where it’s rainier erosion will usually carve pathways to the ocean. They also often have mountains or glaciers blocking their way to the sea. Endorheic basins make up about 18 per cent of the world’s land area - although this map doesn’t show the ones in Antarctica.\nAlso note that 6 of the world’s 25 largest lakes are in endorheic basins - Lakes Turkana, Balkhash, Titicaca, Issyk-kul, and Urmia, and of course the Caspian Sea - the largest lake in all the world.",

        "evidence": "SO/IEC 27001 is an international standard to manage information security. The standard was originally published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in 2005, revised in 2013, and again most recently in 2022. There are also numerous recognized national variants of the standard. It details requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS) – the aim of which is to help organizations make the information assets they hold more secure. Organizations that meet the standard's requirements can choose to be certified by an accredited certification body following successful completion of an audit. The effectiveness of the ISO/IEC 27001 certification process and the overall standard has been addressed in a large-scale study conducted in 2020.\n\nHow the standard works\nMost organizations have a number of information security controls. However, without an information security management system (ISMS), controls tend to be somewhat disorganized and disjointed, having been implemented often as point solutions to specific situations or simply as a matter of convention. Security controls in operation typically address certain aspects of information technology (IT) or data security specifically; leaving non-IT information assets (such as paperwork and proprietary knowledge) less protected on the whole. Moreover, business continuity planning and physical security may be managed quite independently of IT or information security while Human Resources practices may make little reference to the need to define and assign information security roles and responsibilities throughout the organization.\n\nISO/IEC 27001 requires that management:\n\nSystematically examine the organization's information security risks, taking account of the threats, vulnerabilities, and impacts;\nDesign and implement a coherent and comprehensive suite of information security controls and/or other forms of risk treatment (such as risk avoidance or risk transfer) to address those risks that are deemed unacceptable; and\nAdopt an overarching management process to ensure that the information security controls continue to meet the organization's information security needs on an ongoing basis.\nWhat controls will be tested as part of certification to ISO/IEC 27001 is dependent on the certification auditor. This can include any controls that the organisation has deemed to be within the scope of the ISMS and this testing can be to any depth or extent as assessed by the auditor as needed to test that the control has been implemented and is operating effectively.\n\nManagement determines the scope of the ISMS for certification purposes and may limit it to, say, a single business unit or location. The ISO/IEC 27001 certificate does not necessarily mean the remainder of the organization, outside the scoped area, has an adequate approach to information security management.\n\nOther standards in the ISO/IEC 27000 family of standards provide additional guidance on certain aspects of designing, implementing and operating an ISMS, for example on information security risk management (ISO/IEC 27005).\n\nHistory of ISO/IEC 27001\nBS 7799 was a standard originally published by BSI Group in 1995. It was written by the UK government's Department of Trade and Industry (DTI) and consisted of several parts.\n\nThe first part, containing the best practices for information security management, was revised in 1998; after a lengthy discussion in the worldwide standards bodies, it was eventually adopted by ISO as ISO/IEC 17799, \"Information Technology - Code of practice for information security management.\" in 2000. ISO/IEC 17799 was then revised in June 2005 and finally incorporated in the ISO 27000 series of standards as ISO/IEC 27002 in July 2007.\n\nThe second part of BS7799 was first published by BSI in 1999, known as BS 7799 Part 2, titled \"Information Security Management Systems - Specification with guidance for use.\" BS 7799-2 focused on how to implement an Information security management system (ISMS), referring to the information security management structure and controls identified in BS 7799-2. This later became ISO/IEC 27001:2005. BS 7799 Part 2 was adopted by ISO as ISO/IEC 27001 in November 2005.\n\nBS 7799 Part 3 was published in 2005, covering risk analysis and management. It aligns with ISO/IEC 27001:2005.\n\nVery little reference or use is made to any of the BS standards in connection with ISO/IEC 27001.\n\nCertification\nAn ISMS may be certified compliant with the ISO/IEC 27001 standard by a number of Accredited Registrars worldwide. Certification against any of the recognized national variants of ISO/IEC 27001 (e.g. JIS Q 27001, the Japanese version) by an accredited certification body is functionally equivalent to certification against ISO/IEC 27001 itself.\n\nIn some countries, the bodies that verify conformity of management systems to specified standards are called \"certification bodies\", while in others they are commonly referred to as \"registration bodies\", \"assessment and registration bodies\", \"certification/ registration bodies\", and sometimes \"registrars\".\n\nThe ISO/IEC 27001 certification, like other ISO management system certifications, usually involves a three-stage external audit process defined by ISO/IEC 17021 and ISO/IEC 27006 standards:\n\nStage 1 is a preliminary, informal review of the ISMS. For example there are checks for the existence and completeness of key documentation, such as the organization's information security policy, Statement of Applicability (SoA), and Risk Treatment Plan (RTP). This stage serves to familiarize the auditors with the organization and vice versa.\nStage 2 is a more detailed and formal compliance audit, independently testing the ISMS against the requirements specified in ISO/IEC 27001. The auditors will seek evidence to confirm that the management system has been properly designed and implemented, and is in fact in operation (for example by confirming that a security committee or similar management body meets regularly to oversee the ISMS). Certification audits are usually conducted by ISO/IEC 27001 Lead Auditors. Passing this stage results in the ISMS being certified compliant with ISO/IEC 27001.\nOngoing involves follow-up reviews or audits to confirm that the organization remains in compliance with the standard. Certification maintenance requires periodic re-assessment audits to confirm that the ISMS continues to operate as specified and intended. These should happen at least annually but (by agreement with management) are often conducted more frequently, particularly while the ISMS is still maturing.",

        "evidence": "Born in Vienna into one of Europe's richest families, Ludwig Wittgenstein inherited a fortune from his father in 1913.

These included Trakl as well as Rainer Maria Rilke and the architect Adolf Loos.\" Later, in a period of severe personal depression after World War I, he gave away his remaining fortune to his brothers and sisters. Three of his four older brothers died by separate acts of suicide. Wittgenstein left academia several times: serving as an officer on the front line during World War I, where he was decorated a number of times for his courage; teaching in schools in remote Austrian villages, where he encountered controversy for using sometimes violent corporal punishment on girls and a boy (the Haidbauer incident) especially during mathematics classes; working during World War II as a hospital porter in London, notably telling patients not to take the drugs they were prescribed; and working as a hospital laboratory technician at the Royal Victoria Infirmary in Newcastle upon Tyne.

        "question": "What system do they propose?",
        "answer": "A new data management system called Overton that provides abstractions to support the model life cycle by helping build models, manage supervision, and monitor application quality.",
        "evidence": "In the life cycle of many production machine-learning applications, maintaining and improving deployed models is the dominant factor in their total cost and effectiveness–much greater than the cost of de novo model construction. Yet, there is little tooling for model life-cycle support. For such applications, a key task for supporting engineers is to improve and maintain the quality in the face of changes to the input distribution and new production features. This work describes a new style of data management system called Overton that provides abstractions to support the model life cycle by helping build models, manage supervision, and monitor application quality.\nOverton is used in both near-real-time and backend production applications. However, for concreteness, our running example is a product that answers factoid queries, such as “how tall is the president of the united states?” In our experience, the engineers who maintain such machine learning products face several challenges on which they spend the bulk of their time.\nFine-grained Quality Monitoring While overall improvements to quality scores are important, often the week-to-week battle is improving fine-grained quality for important subsets of the input data. An individual subset may be rare but are nonetheless important, e.g., 0.1% of queries may correspond to a product feature that appears in an advertisement and so has an outsized importance. Traditional machine learning approaches effectively optimize for aggregate quality. As hundreds of such subsets are common in production applications, this presents data management and modeling challenges. An ideal system would monitor these subsets and provide tools to improve these subsets while maintaining overall quality.\nSupport for Multi-component Pipelines Even simple machine learning products comprise myriad individual tasks. Answering even a simple factoid query, such as “how tall is the president of the united states?” requires tackling many tasks including (1) find the named entities (`united states', and `president'), (2) find the database ids for named entities, (3) find the intent of the question, e.g., the height of the topic entity, (4) determine the topic entity, e.g., neither president nor united states, but the person Donald J. Trump, who is not explicitly mentioned, and (5) decide the appropriate UI to render it on a particular device. Any of these tasks can go wrong. Traditionally, systems are constructed as pipelines, and so determining which task is the culprit is challenging.\nUpdating Supervision When new features are created or quality bugs are identified, engineers provide additional supervision. Traditionally, supervision is provided by annotators (of varying skill levels), but increasingly programmatic supervision is the dominant form of supervision BIBREF0, BIBREF1, which includes labeling, data augmentation, and creating synthetic data. For both privacy and cost reasons, many applications are constructed using programmatic supervision as a primary source. An ideal system can accept supervision at multiple granularities and resolve conflicting supervision for those tasks.\nThere are other desiderata for such a system, but the commodity machine learning stack has evolved to support them: building deployment models, hyperparameter tuning, and simple model search are now well supported by commodity packages including TensorFlow, containers, and (private or public) cloud infrastructure. By combining these new systems, Overton is able to automate many of the traditional modeling choices, including deep learning architecture, its hyperparameters, and even which embeddings are used.\nOverton provides the engineer with abstractions that allow them to build, maintain, and monitor their application by manipulating data files–not custom code. Inspired by relational systems, supervision (data) is managed separately from the model (schema). Akin to traditional logical independence, Overton's schema provides model independence: serving code does not change even when inputs, parameters, or resources of the model change. The schema changes very infrequently–many production services have not updated their schema in over a year.\nOverton takes as input a schema whose design goal is to support rich applications from modeling to automatic deployment. In more detail, the schema has two elements: (1) data payloads similar to a relational schema, which describe the input data, and (2) model tasks, which describe the tasks that need to be accomplished. The schema defines the input, output, and coarse-grained data flow of a deep learning model. Informally, the schema defines what the model computes but not how the model computes it: Overton does not prescribe architectural details of the underlying model (e.g., Overton is free to embed sentences using an LSTM or a Transformer) or hyperparameters, like hidden state size. Additionally, sources of supervision are described as data–not in the schema–so they are free to rapidly evolve.\nAs shown in Figure FIGREF7, given a schema and a data file, Overton is responsible to instantiate and train a model, combine supervision, select the model's hyperparameters, and produce a production-ready binary. Overton compiles the schema into a (parameterized) TensorFlow or PyTorch program, and performs an architecture and hyperparameter search. A benefit of this compilation approach is that Overton can use standard toolkits to monitor training (TensorBoard equivalents) and to meet service-level agreements (Profilers). The models and metadata are written to an S3-like data store that is accessible from the production infrastructure. This has enabled model retraining and deployment to be nearly automatic, allowing teams to ship products more quickly.\nIn retrospect, the following three choices of Overton were the most important in meeting the above challenges.\n(1) Code-free Deep Learning In Overton-based systems, engineers focus exclusively on fine-grained monitoring of their application quality and improving supervision–not tweaking deep learning models. An Overton engineer does not write any deep learning code in frameworks like TensorFlow. To support application quality improvement, we use a technique, called model slicing BIBREF3. The main idea is to allow the developer to identify fine-grained subsets of the input that are important to the product, e.g., queries about nutrition or queries that require sophisticated disambiguation. The system uses developer-defined slices as a guide to increase representation capacity. Using this recently developed technique led to state-of-the-art results on natural language benchmarks including GLUE and SuperGLUE BIBREF4.\n(2) Multitask Learning Overton was built to natively support multitask learning BIBREF5, BIBREF6, BIBREF7 so that all model tasks are concurrently predicted. A key benefit is that Overton can accept supervision at whatever granularity (for whatever task) is available. Overton models often perform ancillary tasks like part-of-speech tagging or typing. Intuitively, if a representation has captured the semantics of a query, then it should reliably perform these ancillary tasks. Typically, ancillary tasks are also chosen either to be inexpensive to supervise. Ancillary task also allow developers to gain confidence in the model's predictions and have proved to be helpful for aids for debugging errors.\n(3) Weak Supervision Applications have access to supervision of varying quality and combining this contradictory and incomplete supervision is a major challenge. Overton uses techniques from Snorkel BIBREF1 and Google's Snorkel DryBell BIBREF0, which have studied how to combine supervision in theory and in software. Here, we describe two novel observations from building production applications: (1) we describe the shift to applications which are constructed almost entirely with weakly supervised data due to cost, privacy, and cold-start issues, and (2) we observe that weak supervision may obviate the need for popular methods like transfer learning from massive pretrained models, e.g., BERT BIBREF8–on some production workloads, which suggests that a deeper trade-off study may be illuminating.\nIn summary, Overton represents a first-of-its kind machine-learning lifecycle management system that has a focus on monitoring and improving application quality. A key idea is to separate the model and data, which is enabled by a code-free approach to deep learning. Overton repurposes ideas from the database community and the machine learning community to help engineers in supporting the lifecycle of machine learning toolkits. This design is informed and refined from use in production systems for over a year in multiple machine-learned products.\nThis work describes a new style of data management system called Overton that provides abstractions to support the model life cycle by helping build models, manage supervision, and monitor application quality.",

        "answer": "The main reason is that the basic augmentations are adopted from a previous paper [14], which have been manually tuned to generate relatively good performances for contrastive learning. For these reasons, significant improvements on different variants of our methods are impractical and unreasonable. In fact, in the initial version, we have conducted some experiments on classification which adopts ACC as the metric, using both good and bad basic augmentations. As shown in Figure 3, augmentations with high variety and high fidelity can achieve good accuracy performance with significant improvement. To further take the reviewers' comments into consideration, we have conducted more experiments in Appendix D.3.2 with more low-quality augmentations.  The gaps between different variants are more obvious, demonstrating that both variety and fidelity make contributions to the superior performances of InfoTS.",
        "evidence": "To present deep insights into the proposed method, we verify key components in InfoTS with multiple ablation studies on the Electricity dataset. Results are shown in Table. 1) We verify the effectiveness of the adopted contrastive learning objective, Eq. (), by comparing InfoTS with its two variants. \"w/o Local\" removes the local contrastive loss between subsequences and \"w/o Global\" removes the instance-level contrastive loss. The comparison between these variants and InfoTS demonstrates that both instance-level and intra-temporal objectives are important in contrastive learning for time series data. 2) To demonstrate the advantage of adaptive selection of augmentations, we compare InfoTS with variants \"Random\" and \"All\". \"Random\" randomly selects an augmentation from candidate transformation functions each time and \"All\" sequentially applies transformations to generate augmented instances. Performance decreases are observed in these variances, verifying the key role of adaptive selection in our method. 3) To show the effects of variety and fidelity objectives in meta-network training, we include two variants, \"w/o Fidelity\" and \"w/o Variety\", which dismiss the fidelity or variety objective, respectively. The comparison between InfoTS and the variants empirically confirms both variety and fidelity are important for data augmentation in contrastive learning. Note that the adopted basic augmentations are manually tuned in a previous paper with high qualities for contrastive learning. Including low quality basic augmentations, we conduct more ablation studies are shown in Appendix D.3.\nThe comparison between InfoTS and the variants empirically confirms both variety and fidelity are important for data augmentation in contrastive learning. Note that the adopted basic augmentations are manually tuned in a previous paper (Fan et al., 2020) with high qualities for contrastive learning. Including low quality basic augmentations, we conduct more ablation studies are shown in Appendix D.3.****In Section 2.2, we propose criteria of data augmentations for time series based on information theory that good augmentations should have high variety and fidelity. With mutual information neural estimation and cross-entropy as approximations, we get the criteria in Eq. (5). To empirically verify the effectiveness of the proposed criteria, we adopt the dataset CricketX from the UCR archive (Dau et al., 2019; Fan et al., 2020), and conduct augmentations with different configurations, such as jittering with noise from N (0, 0.3) and cutout 10% time stamps. For each configuration, we calculate the criteria score and the corresponding classification accuracy within the setting in Section 4.2. As shown in Figure 3, in general, accuracy performance is positively related to the proposed criteria in both supervised and unsupervised settings, verifying the correctness of using the criteria as the objective in the meta-network training.",

The goal of QC is to assign classes accurately to the questions based on expected answer. In modern system, there are two types of questions BIBREF0. One is Factoid question which is about providing concise facts and another one is Complex question that has a presupposition which is complex. Question Answering (QA) System is an integral part of our daily life because of the high amount of usage of Internet for information acquisition. In recent years, most of the research works related to QA are based on English language such as IBM Watson, Wolfram Alpha. Bengali speakers often fall in difficulty while communicating in English BIBREF1.\nIn this research, we briefly discuss the steps of QA system and compare the performance of seven machine learning based classifiers (Multi-Layer Perceptron (MLP), Naive Bayes Classifier (NBC), Support Vector Machine (SVM), Gradient Boosting Classifier (GBC), Stochastic Gradient Descent (SGD), K Nearest Neighbour (K-NN) and Random Forest (RF)) in classifying Bengali questions to classes based on their anticipated answers. Bengali questions have flexible inquiring ways, so there are many difficulties associated with Bengali QC BIBREF0. As there is no rich corpus of questions in Bengali Language available, collecting questions is an additional challenge. Different difficulties in building a QA System are mentioned in the literature BIBREF2 BIBREF3. The first work on a machine learning based approach towards Bengali question classification is presented in BIBREF0 that employ the Stochastic Gradient Descent (SGD).\nOne is Factoid question which is about providing concise facts and another one is Complex question that has a presupposition which is complex.",

When the car pulled behind the grandstands, one teenager fired on a crowd of 300 people with a shotgun, causing seven people to receive injuries. Six of the injured were teenagers, ranged in age from 13 to 19. One received critical injuries. All six received treatment at the Detroit Receiving Hospital. The shootings occurred at 4:15 PM, and the suspects left the scene. This shooting was the week's second shooting that had high school students involved. The shooting was the second one in a month in which Homecoming activities were involved. Police said that one of the suspects had been involved in a fight on an earlier occasion.\n\nOn April 16, 1987, a student at Murray–Wright entered the school parking lot and shot 17-year-old Chester Jackson, a junior running back, in the head, killing him. The attacker went into the gymnasium and shot 18-year-old Damon Matthews, a basketball player, in the face. Tomeka Turner, an 18-year-old, was wounded. Risen said that Turner's injuries occurred \"apparently in the school's corridors as the attacker fled the building.\" The youth with facial injuries received treatment at the Detroit Receiving Hospital. The incident occurred around noon. The attacker, Michael Schofield, was 14 at the time of the crime. Schofield, 15 years old at sentencing, was sentenced to serve in a juvenile correctional facility until he turned 19. Schofield killed four people in 2003 during an attempted robbery of a convenience store in Westland, Michigan, and then killed himself. The Los Angeles Times News Service said that the 1987 Murray–Wright shooting was the incident that put \"most clearly into focus\" the epidemic of youth violence in Detroit.\n\nAfter the murder and shootings, school officials started a plan to reduce violence in the school. The school was closed for two days as officials held special assemblies concerning school violence. The school officials said that of the students who appeared at the assemblies at Murray–Wright, half appeared with their parents. This occurred despite fears that few parents would appear.",

        "evidence": "Neural network based models have been widely exploited with the prosperities of Deep Learning BIBREF0 and achieved inspiring performances on many NLP tasks, such as text classification BIBREF1 , BIBREF2 , semantic matching BIBREF3 , BIBREF4 and machine translation BIBREF5 . These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nThese models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types: • Type-I One dataset annotated with multiple labels and one input with multiple outputs. • Type-II Multiple datasets with respective labels and one input with multiple outputs, where samples from different tasks are fed one by one into the models sequentially. • Type-III Multiple datasets with respective labels and multiple inputs with multiple outputs, where samples from different tasks are jointly learned in parallel.",

BERT is a multi-layer bidirectional transformer encoder trained on the English Wikipedia and the Book Corpus containing 2,500M and 800M tokens, respectively, and has two models named BERTbase and BERTlarge. BERTbase contains an encoder with 12 layers (transformer blocks), 12 self-attention heads, and 110 million parameters whereas BERTlarge has 24 layers, 16 attention heads, and 340 million parameters. Extracted embeddings from BERTbase have 768 hidden dimensions BIBREF11. As the BERT model is pre-trained on general corpora, and for our hate speech detection task we are dealing with social media content, therefore as a crucial step, we have to analyze the contextual information extracted from BERT' s pre-trained layers and then fine-tune it using annotated datasets. By fine-tuning we update weights using a labelled dataset that is new to an already trained model. As an input and output, BERT takes a sequence of tokens in maximum length 512 and produces a representation of the sequence in a 768-dimensional vector. BERT inserts at most two segments to each input sequence, [CLS] and [SEP]. [CLS] embedding is the first token of the input sequence and contains the special classification embedding which we take the first token [CLS] in the final hidden layer as the representation of the whole sequence in hate speech classification task. The [SEP] separates segments and we will not use it in our classification task. To perform the hate speech detection task, we use BERTbase model to classify each tweet as Racism, Sexism, Neither or Hate, Offensive, Neither in our datasets. In order to do that, we focus on fine-tuning the pre-trained BERTbase parameters. By fine-tuning, we mean training a classifier with different layers of 768 dimensions on top of the pre-trained BERTbase transformer to minimize task-specific parameters.\nHere, four different finetuning approaches are implemented that exploit pre-trained BERTbase transformer encoders for our classification task.",

        "evidence": "We applied this method to discover gender-associated words in both domains. In Table TABREF9, we present a sample of the most gender-associated nouns from the celebrity domain. Several themes emerge: for example, female celebrities seem to be more associated with appearance (“gown,” “photo,” “hair,” “look”), while male celebrities are more associated with creating content (“movie,” “film,” “host,” “director”). This echoes real-world trends: for instance, on the red carpet, actresses tend to be asked more questions about their appearance –- what brands they are wearing, how long it took to get ready, etc. –- while actors are asked questions about their careers and creative processes (as an example, see BIBREF31).\nTable TABREF9 also includes some of the most gender-associated verbs and adjectives from the professor domain. Female CS professors seem to be praised for being communicative and personal with students (“respond,” “communicate,” “kind,” “caring”), while male CS professors are recognized for being knowledgeable and challenging the students (“teach,”, “challenge,” “brilliant,” “practical”). These trends are well-supported by social science literature, which has found that female teachers are praised for “personalizing” instruction and interacting extensively with students, while male teachers are praised for using “teacher as expert” styles that showcase mastery of material BIBREF32.\nThese findings establish that there are clear differences in how people talk about women and men – even with Bonferroni correction, there are still over 500 significantly gender-associated nouns, verbs, and adjectives in the celebrity domain and over 200 in the professor domain. Furthermore, the results in both domains align with prior studies and real world trends, which validates that our methods can capture meaningful patterns and innovatively provide evidence at the large-scale. This analysis also hints that it can be helpful to abstract from words to topics to recognize higher-level patterns of gender associations, which motivates our next section on clustering.\nTable TABREF11 displays a sample of our results – we find that the clusters are coherent in context and the labels seem reasonable. In the next section, we discuss human evaluations that we conducted to more rigorously evaluate the output, but first we discuss the value of these methods toward analysis.\nAt the word-level, we hypothesized that in the celebrity domain, women were more associated with appearance and men with creating content. Now, we can validate those hypotheses against labeled clusters – indeed, there is a cluster labeled clothing that is 100% female (i.e. 100% words are female-associated), and a 80% male cluster labeled movie. Likewise, in the professor domain, we had guessed that women are associated with communication and men with knowledge, and there is a 100% female cluster labeled communication and a 89% male cluster labeled cognition. Thus, cluster labeling proves to be very effective at pulling out the patterns that we believed we saw at the word-level, but could not formally validate.\nThe clusters we mentioned so far all lean heavily toward one gender association or the other, but some clusters are interesting precisely because they do not lean heavily – this allows us to see where semantic groupings do not align exactly with gender association. For example, in the celebrity domain, there is a cluster labeled lover that has a mix of female-associated words (“boyfriend,” “beau,” “hubby”) and male-associated words (“wife,” “girlfriend”). Jointly leveraging cluster labels and gender associations allows us to see that in the semantic context of having a lover, women are typically associated with male figures and men with female figures, which reflects heteronormativity in society.\nThus, cluster labeling proves to be very effective at pulling out the patterns that we believed we saw at the word-level, but could not formally validate.",

Another part of the story was a patent dispute in 1898 between Thomas Edison and his patent for the Kinetograph.  Edison stated that he effectively had a say in how films were made and wanted royalties for their use.  Moving from New York near where Edison was based to Los Angeles was a simple way to grow the industry and distance themselves from a patent war.  \n\nThis mobility at the start of the modern film era due to costs continued through the 1960's and 1970's with westerns being shot in Spain.  The 1980's and 1990's continued this trend primarily shooting in Canada or Mexico.  At the turn of the century state legislators in the United States started provided steep tax rebates.  The practical outworking of this is studios are encouraged to hire local talent and use local services when producing their film.  The ratios for these rebates is fairly complicated and have created a new industry of tax professionals serving the film industry.\n\nSo then why Georgia?

        "answer": "To train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages their dataset consists of.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nEssentially, we train Continuous Bag-of-Words models on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity.",

In the first study, we tackle the problem of relatively high “noise” in the retrieved data. In particular, not all of the documents are related to the given topics in a way that makes them candidates for further deep analysis of argumentation (this study results into 990 annotated documents). In the second study, we discuss the selection of an appropriate argumentation model based on evidence in argumentation research and propose a model that is suitable for analyzing micro-level argumention in user-generated Web content. Using this model, we annotate 340 documents (approx. 90,000 tokens), reaching a substantial inter-annotator agreement. We provide a hand-analysis of all the phenomena typical to argumentation that are prevalent in our data. These findings may also serve as empirical evidence to issues that are on the spot of current argumentation research.\nFrom the computational perspective, we experiment on the annotated data using various machine learning methods in order to extract argument structure from documents. We propose several novel feature sets and identify configurations that run best in in-domain and cross-domain scenarios. To foster research in the community, we provide the annotated data as well as all the experimental software under free license.\nThe rest of the article is structured as follows.

Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension.

        "evidence": "In this work, we have proposed an automated approach for the novel task of suggesting news articles to Wikipedia entity pages to facilitate Wikipedia updating. The process consists of two stages. In the first stage, article–entity placement, we suggest news articles to entity pages by considering three main factors, such as entity salience in a news article, relative authority and novelty of news articles for an entity page. In the second stage, article–section placement, we determine the best fitting section in an entity page. Here, we remedy the problem of incomplete entity section profiles by constructing section templates for specific entity classes. This allows us to add missing sections to entity pages. We carry out an extensive experimental evaluation on 351,983 news articles and 73,734 entities coming from 27 distinct entity classes. For the first stage, we achieve an overall performance with P=0.93, R=0.514 and F1=0.676, outperforming our baseline competitors significantly. For the second stage, we show that we can learn incrementally to determine the correct section for a news article based on section templates. The overall performance across different classes is P=0.844, R=0.885 and F1=0.860.\nIn the future, we will enhance our work by extracting facts from the suggested news articles. Results suggest that the news content cited in entity pages comes from the first paragraphs. However, challenging task such as the canonicalization and chronological ordering of facts, still remain.\nResults suggest that the news content cited in entity pages comes from the first paragraphs.",

        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nIn this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations (Kim, 2014), and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models",

As a result, the host favors endosymbiont's growth processes within itself by producing some specialized cells.

Forward perplexity (PPL-F) indicates the perplexity on the generated data provided by a language model trained on real data to measure the fluency of generated samples. Reverse perplexity (PPL-R) switches the roles of generated data and real data to reflect the discrepancy between the generated distribution and the data distribution. Self-BLEU (S-BLEU) regards each sentence in the generated collection as hypothesis and the others as reference to obtain BLEU scores, which evaluates the diversity of generated results.\nResults are shown in Table TABREF33 . LeakGAN performs best on forward perplexity because it can generate more fluent samples. As for reverse perplexity, our model ARAML beats other baselines, showing that our model can fit the data distribution better.

        "question": "Why did Ken Shamrock change his last name?",
        "evidence": "Kenneth Wayne Shamrock (né Kilpatrick; born February 11, 1964) is an American bare-knuckle boxing promoter and semi-retired professional wrestler, mixed martial artist, and kickboxer. He is best known for his time in Ultimate Fighting Championship (UFC) and other combat sports. A member of the UFC Hall of Fame, Shamrock is widely regarded as an icon and pioneer of the sport. He has headlined over 15 main events and co-main events in the UFC and Pride FC and set numerous MMA pay-per-view records. In the early part of his UFC career, Shamrock was named \"The World's Most Dangerous Man\" by ABC News in a special called \"The World's Most Dangerous Things\". The moniker has stuck as his nickname.\n\nShamrock became known early on in the UFC for his rivalry with Royce Gracie. After fighting to a draw in the inaugural UFC \"Superfight\", he became the first UFC Superfight Champion when he defeated Dan Severn at UFC 6; the title was eventually replaced by the UFC Heavyweight Championship when weight categories were introduced to the UFC. He was also the first foreign MMA champion in Japan, winning the title of King of Pancrase Openweight title. During his reign as the UFC Superfight Champion, he was widely considered the #1 mixed martial artist in the world, and in 2008, Shamrock was ranked by Inside MMA as one of the top 10 greatest mixed martial arts fighters of all time. He is the founder of the Lion's Den mixed martial arts training camp, and is the older brother of fellow fighter Frank Shamrock.\n\nIn addition to his mixed martial arts career, Shamrock enjoyed considerable success in professional wrestling, particularly during his tenure with the World Wrestling Federation (WWF, now WWE). There, he is a one-time Intercontinental Champion, a one-time World Tag Team Champion and the 1998 King of the Ring. Shamrock also wrestled for Total Nonstop Action Wrestling (TNA, now Impact Wrestling), where he is a one-time NWA World Heavyweight Champion – the first world champion under the TNA banner – and a 2020 inductee in the Impact Hall of Fame. He headlined multiple pay-per-view events in both promotions, including 1997's D-Generation X: In Your House, where he challenged for the WWF Championship. Additionally, Shamrock was also one of the first wrestlers to use the shoot style of wrestling in America, being credited by WWE with popularizing the legitimate ankle lock submission hold.\n\nA \"military brat,\" Kilpatrick was born at Robins Air Force Base, in Warner Robins, Georgia, where he lived for his first four years. His father Richard Kilpatrick was a United States Air Force enlistee, and his mother Diane Kilpatrick was a waitress and dancer who had her first son when she was 15. Shamrock had three brothers and came from a broken family in a predominantly black neighborhood of Atlanta, Georgia.\n\nHe was often left to fend for himself, and, without his parents' supervision or guidance, got into many fights. His father abandoned his family when Shamrock was five. His mother married an Army aviator named Bob Nance, and the newly formed family moved to Napa, California, Nance's hometown. Shamrock and his brothers were outsiders in this community, coming from a poor background and speaking in a Southern accent. They continued to cause trouble and get into fights and began using drugs. Nance, who fought in the Vietnam War, joined the local fire department and also worked in roofing and upholstery. Shamrock became involved in and excelled at sports at a young age, playing in Little League baseball and Pop Warner football. Nance remembers a veteran coach telling him that he had never seen a player with as much heart and tenacity as the young Shamrock. Shamrock was not as involved with drugs as his brothers, such as his brother Richie, who enjoyed smoking marijuana and eventually using heroin intravenously, but who also played football.\n\nAt age 10, Shamrock ran away from home for the first time, and was stabbed by another child on the run, ending up in the hospital. When he was 13, his stepfather kicked him out of their home, and each of the brothers went their own ways. Shamrock lived in cars before being placed in a foster home. He went through seven group homes and served time in a juvenile hall. He moved between several more group homes before being placed in Bob Shamrock's Boys' Home at age 14 in Susanville, California where he turned his life around. Bob Shamrock legally adopted Ken as his son, and Ken changed his last name from Kilpatrick to Shamrock in Bob's honor.\n\nAt Lassen High School, Shamrock (known there as Kenny Nance) excelled in football and wrestling. As a senior, he qualified for the state championships in wrestling, but broke his neck in practice days before the competition and underwent neck surgery. He received no scholarship offers from any big colleges, and doctors told him his sports career was likely over. Against doctors' orders, he joined the Shasta College football team, where he was voted team captain in his final season. The San Diego Chargers of the National Football League later offered him a tryout, but he declined in order to pursue a career in professional wrestling, where he debuted in 1989 in the South Atlantic Pro Wrestling promotion.",

        "evidence": "",
        "answer": "Indian and Western music differ considerably in terms of pitch because Western music adheres to the concept of absolute pitch, while Indian music predominantly focuses on relative pitch. Absolute pitch means that a note is represented as an absolute frequency, so if someone says \"A2\", that pitch can be mapped back to an exact frequency, and therefore can be reconciled among many different styles of music and instrumentation. \n\nIn contrast, much of Indian music (both classical and non-classical) uses the concept of relative pitch, which means that the musician sets a tonic note (their base note) and that pitch is the starting point for all other notes. For example, if one musician were to say that a specific pitch were \"sa\" (one of the 7 notes in the Indian music scale), another musician would not be able to reproduce that note, since they wouldn't know where the first musician set their tonic. However, this has other advantages,  because a tune is defined in terms of relative pitch and can be reproduced easily among different musicians and instruments without the worry of an absolute frequency which cannot be reached by a specific musical range.",

        "question": "Given these paragraphs about Large language models, when did LLMs emerge?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

Everyday millions of tweets are generated about local and global news, including people reactions and opinions regarding the events displayed on those news stories. Trending personalities, organizations, companies or geographic locations are building blocks of news stories and their comments. We propose to extract entities from tweets and their associated context in order to understand what is being said on Twitter about those entities and consequently to create a picture of people reactions to recent events.\nWith this in mind and using text mining techniques, this work explores and evaluates ways to characterize given entities by finding: (a) the main terms that define that entity and (b) the sentiment associated with it. To accomplish these goals we use topic modeling BIBREF1 to extract topics and relevant terms and phrases of daily entity-tweets aggregations, as well as, sentiment analysis BIBREF2 to extract polarity of frequent subjective terms associated with the entities. Since public opinion is, in most cases, not constant through time, this analysis is performed on a daily basis. Finally we create a data visualization of topics and sentiment that aims to display these two dimensions in an unified and intelligible way.\nThe combination of Topic Modeling and Sentiment Analysis has been attempted before: one example is a model called TSM - Topic-Sentiment Mixture Model BIBREF3 that can be applied to any Weblog to determine a correlation between topic and sentiment. Another similar model has been proposed proposed BIBREF4 in which the topic extraction is achieved using LDA, similarly to the model that will be presented. Our work distinguishes from previous work by relying on daily entity-centric aggregations of tweets to create a meta-document which will be used as input for topic modeling and sentiment analysis.\nTo accomplish these goals we use topic modeling to extract topics and relevant terms and phrases of daily entity-tweets aggregations, as well as, sentiment analysis to extract polarity of frequent subjective terms associated with the entities.",

        "question": "Does the general translation performance as measured by BLEU decrease?",
        "answer": "Yes, it does.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nWe find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.",

        "question": "How do authors train the bidirectional RNN with an attention mechanism?",
        "answer": "Train the mechanism with word embeddings.",
        "evidence": "Author profiling is the characterization of an author through some key attributes such as gender, age, and language. It's an indispensable task especially in security, forensics, and marketing. Recently, social media has become a great data source for the potential learning approaches. Furthermore, gender prediction has been a popular profiling task.\nThe traditional approach to gender prediction problem is extracting a useful set of hand-crafted features and then feeding them into a standard classification algorithm. In their study, BIBREF0 work with the style-based features of message length, stop word usage, frequency of smiley etc. and use different classifiers such as k-nearest neighbor, naive bayes, covering rules, and backpropagation to predict gender on chat messages. Similarly, BIBREF1 select some hand-crafted features and feed them into various classifiers.\nMost of the work on gender prediction rely on n-gram features BIBREF2. BIBREF3 give Latent Semantic Analysis (LSA)-reduced forms of word and character n-grams into Support Vector Machine (SVM) and achieve state-of-the-art performance. Apart from exploiting n-gram frequencies, there are studies BIBREF4, BIBREF5, BIBREF6 to extract cross-lingual features to determine gender from tweets. Some other work BIBREF4, BIBREF7 exploit user metadata besides using just tweets.\nRecently, neural network-based models have been proposed to solve this problem. Rather than explicitly extracting features, the aim is to develop an architecture that implicitly learns. In author profiling, both style and content-based features were proved useful BIBREF8 and neural networks are able to capture both syntactic and semantic regularities. In general, syntactic information is drawn from the local context. On the other hand, semantic information is often captured with larger window sizes. Thus, CNNs are preferred to obtain style-based features while RNNs are the methods of choice for addressing content-based features BIBREF9. In literature, CNN BIBREF10 or RNN BIBREF11, BIBREF12, BIBREF13 is used on this task. BIBREF11 obtain state-of-the-art performance among neural methods by proposing a model architecture where they process text through RNN with GRU cells. Also, the presence of an attention layer is shown to boost the performance of neural methods BIBREF11, BIBREF10.\nIn this work, we propose a model that relies on RNN with attention mechanism (RNNwA). A bidirectional RNN with attention mechanism both on word level and tweet level is trained with word embeddings. The final representation of the user is fed to a fully connected layer for prediction. Since combining some hand-crafted features with a learned linear layer has shown to perform well in complex tasks like Semantic Role Labeling (SRL) BIBREF14, an improved version of the model (RNNwA + n-gram) is also tested with hand-crafted features. In the improved version, LSA-reduced n-gram features are concatenated with the neural representation of the user. Then the result is fed into a fully-connected layer to make prediction. Models are tested in three languages; English, Spanish, and Arabic, and the improved version achieves state-of-the-art accuracy on English, and competitive results on Spanish and Arabic corpus.\nThere are many datasets created for this task BIBREF15, BIBREF16. In this work, we have used the dataset and benchmarks provided by the PAN 2018 shared task on author profiling BIBREF15. As the dataset contains a constant number of 100 tweets per user, accuracy tests are performed both on user and tweet level (tweet-level predictions are made by removing the user-level attention). Tweet-level accuracy tests show interesting results during hyperparameter optimization. When the tweet-level predictions are averaged to produce user-level predictions, it is seen that the hyperparameters that gave the best results in terms of tweet-level accuracy, performs worse in user-level accuracy. The better user-level models, with different hyperparameters, that gave the highest user-level accuracy are observed to slightly overfit on tweet-level. It leads us to believe that the overfitting in the tweet-level predictions in best user-level models acts similar to an attention mechanism by over-emphasizing some distinctive tweets and ignoring the rest.\nA bidirectional RNN with attention mechanism both on word level and tweet level is trained with word embeddings.",

        "evidence": "The concept of customer relationship management started in the early 1970s, when customer satisfaction was evaluated using annual surveys or by front-line asking. At that time, businesses had to rely on standalone mainframe systems to automate sales, but the extent of technology allowed them to categorize customers in spreadsheets and lists. One of the best-known precursors of the modern-day CRM is the Farley File. Developed by Franklin Roosevelt’s campaign manager, James Farley, the Farley File was a comprehensive set of records detailing political and personal facts on people FDR and Farley met or were supposed to meet. Using it, people that FDR met were impressed by his \"recall\" of facts about their family and what they were doing professionally and politically. In 1982, Kate and Robert D. Kestenbaum introduced the concept of database marketing, namely applying statistical methods to analyze and gather customer data.[citation needed] By 1986, Pat Sullivan and Mike Muhney released a customer evaluation system called ACT! based on the principle of digital Rolodex, which offered a contact management service for the first time.\n\nThe trend was followed by numerous companies and independent developers trying to maximize lead potential, including Tom Siebel of Siebel Systems, who designed the first CRM product, Siebel Customer Relationship Management, in 1993. In order to compete with these new and quickly growing stand-alone CRM solutions, the established enterprise resource planning (ERP) software companies like Oracle, SAP, Peoplesoft (an Oracle subsidiary as of 2005) and Navision started extending their sales, distribution and customer service capabilities with embedded CRM modules. This included embedding sales force automation or extended customer service (e.g. inquiry, activity management) as CRM features in their ERP.\n\nCustomer relationship management was popularized in 1997, due to the work of Siebel, Gartner, and IBM. Between 1997 and 2000, leading CRM products were enriched with shipping and marketing capabilities. Siebel introduced the first mobile CRM app called Siebel Sales Handheld in 1999. The idea of a stand-alone, cloud-hosted customer base was soon adopted by other leading providers at the time, including PeopleSoft (acquired by Oracle), Oracle, SAP and Salesforce.com.\n\nThe first open-source CRM system was developed by SugarCRM in 2004. During this period, CRM was rapidly migrating to the cloud, as a result of which it became accessible to sole entrepreneurs and small teams. This increase in accessibility generated a huge wave of price reduction. Around 2009, developers began considering the options to profit from social media's momentum and designed tools to help companies become accessible on all users' favourite networks. Many startups at the time benefited from this trend to provide exclusively social CRM solutions, including Base and Nutshell. The same year, Gartner organized and held the first Customer Relationship Management Summit, and summarized the features systems should offer to be classified as CRM solutions. In 2013 and 2014, most of the popular CRM products were linked to business intelligence systems and communication software to improve corporate communication and end-users' experience. The leading trend is to replace standardized CRM solutions with industry-specific ones, or to make them customizable enough to meet the needs of every business. In November 2016, Forrester released a report where it \"identified the nine most significant CRM suites from eight prominent vendors\"",

We assume the soft-label black-box setting where the attacker can only query the classifier for output probabilities on a given input, and does not have access to the model parameters, gradients or training data. For an input pair $(\\mathbb {S},y)$, we want to generate an adversarial example $\\mathbb {S}_{adv}$ such that $C(\\mathbb {S}_{adv}){\\ne }y$ where $\\mathbb {S}_{adv}$ is natural looking, grammatically correct and semantically similar to $\\mathbb {S}$ (by some pre-defined definition\nof similarity).\nBAE For generating adversarial example $\\mathbb {S}_{adv}$, we define two perturbations on the input $\\mathbb {S}$:\nReplace a token $t \\in \\mathbb {S}$ with another\nInsert a new token $t^{\\prime }$ in $\\mathbb {S}$\nSome tokens in the input are more attended to by $C$ than others, and therefore contribute more towards the final prediction. Replacing these tokens or inserting a new token adjacent to them can thus have a stronger effect on altering the classifier prediction. We estimate the token importance $I_i$ of each token $t_i \\in \\mathbb {S}=[t_1, \\dots , t_n]$, by deleting $t_i$ from $\\mathbb {S}$ and computing the decrease in probability of predicting the correct label $y$, similar to BIBREF11.\nWhile the motivation for replacing tokens in decreasing order of importance is clear, we conjecture that adjacent insertions in this same order can lead to a powerful attack. This intuition stems from the fact that the inserted token changes the local context around the original token.\nThe Replace (R) and Insert (I) operations are performed on a token $t$ by masking it and inserting a mask token adjacent to it in $\\mathbb {S}$ respectively. The pre-trained BERT masked language model (MLM) is used to predict the mask tokens (See Figure FIGREF1).\nBERT is a powerful LM trained on a large training corpus ($\\sim $ 2 billion words), and hence the predicted mask tokens fit well grammatically in $\\mathbb {S}$. The BERT-MLM does not however guarantee semantic coherence to the original text $\\mathbb {S}$ as demonstrated by the following simple example. Consider the sentence: `the food was good'. For replacing the token `good', BERT-MLM may predict the tokens `nice' and `bad', both of which fit well into the context of the sentence. However, replacing `good' with `bad' changes the original sentiment of the sentence.\nTo ensure semantic similarity on introducing perturbations in the input text, we filter the set of top K masked tokens (K is a pre-defined constant) predicted by BERT-MLM using a Universal Sentence Encoder (USE) BIBREF14 based sentence similarity scorer. For the R operations we add an additional check for grammatical correctness of the generated adversarial example by filtering out predicted tokens that do not form the same part of speech (POS) as the original token $t_i$ in the sentence.\nTo choose the token for a perturbation (R/I) that best attacks the model from the filtered set of predicted tokens:\nIf there are multiple tokens can cause $C$ to misclassify $\\mathbb {S}$ when they replace the mask, we choose the token which makes $\\mathbb {S}_{adv}$ most similar to the original $\\mathbb {S}$ based on the USE score.\nIf no token causes misclassification, we choose the perturbation that decreases the prediction probability $P(C(\\mathbb {S}_{adv}){=}y)$ the most.\nThe perturbations are applied iteratively to the input tokens in decreasing order of importance, until either $C(\\mathbb {S}_{adv}){\\ne }y$ (successful attack) or all the tokens of $\\mathbb {S}$ have been perturbed (failed attack).\nWe present 4 attack modes for BAE based on the R and I operations, where for each token $t$ in $\\mathbb {S}$:\nBAE-R: Replace token $t$ (See Algorithm )\nBAE-I: Insert a token to the left or right of $t$\nBAE-R/I: Either replace token $t$ or insert a token to the left or right of $t$\nBAE-R+I: First replace token $t$, then insert a token to the left or right of $t$\nFor generating an adversarial example Sadv, we introduce 2 types of token-level perturbations: (i) Replace a token t ∈ S with another and (ii) Insert a new token t 0 in S.",

        "question": "What does the second dataset contain?",
        "answer": "The second dataset contains reviews from RateMyProfessors (RMP), an online platform where students can review their professors.",
        "evidence": "Our first dataset contains articles from celebrity magazines People, UsWeekly, and E!News. We labeled each article for whether it was reporting on men, women, or neither/unknown. To do this, we first extracted the article's topic tags. Some of these tags referred to people, but others to non-people entities, such as “Gift Ideas” or “Health.” To distinguish between these types of tags, we queried each tag on Wikipedia and checked whether the top page result contained a “Born” entry in its infobox – if so, we concluded that the tag referred to a person.\nThen, from the person's Wikipedia page, we determined their gender by checking whether the introductory paragraphs of the page contained more male or female pronouns. This method was simple but effective, since pronouns in the introduction almost always resolve to the subject of that page. In fact, on a sample of 80 tags that we manually annotated, we found that comparing pronoun counts predicted gender with perfect accuracy. Finally, if an article tagged at least one woman and did not tag any men, we labeled the article as Female; in the opposite case, we labeled it as Male.\nOur second dataset contains reviews from RateMyProfessors (RMP), an online platform where students can review their professors. We included all 5,604 U.S. schools on RMP, and collected all reviews for CS professors at those schools. We labeled each review with the gender of the professor whom it was about, which we determined by comparing the count of male versus female pronouns over all reviews for that professor. This method was again effective, because the reviews are expressly written about a certain professor, so the pronouns typically resolve to that professor.\nIn addition to extracting the text of the articles or reviews, for each dataset we also collected various useful metadata. For the celebrity dataset, we recorded each article's timestamp and the name of the author, if available. Storing author names creates the potential to examine the relationship between the gender of the author and the gender of the subject, such as asking if there are differences between how women write about men and how men write about men. In this work, we did not yet pursue this direction because we wanted to begin with a simpler question of how gender is discussed: regardless of the gender of the authors, what is the content being put forth and consumed? Furthermore, we were unable to extract author gender in the professor dataset since the RMP reviews are anonymous. However, in future work, we may explore the influence of author gender in the celebrity dataset.\nFor the professor dataset, we captured metadata such as each review's rating, which indicates how the student feels about the professor on a scale of AWFUL to AWESOME. This additional variable in our data creates the option in future work to factor in sentiment; for example, we could study whether there are differences in language used when criticizing a female versus a male professor.\nOur second dataset contains reviews from RateMyProfessors (RMP), an online platform where students can review their professors.",

        "answer": "New AI-augmented analytics platform takes the guesswork and grunt work out of business intelligence with pre-built metrics, models and radically simple user experience.  The cloud-based solution empowers leaders of subscription businesses to monitor, diagnose and optimize their business without employing teams of data analysts and data scientists.\n\nForward-looking organizations of all sizes are looking to data for a competitive edge.  Advances in data science and the ever expanding sources of data offer the raw ingredients for greater efficiency and insights. Despite heavy investments in modern analytics tooling, businesses continue to find their analysts overwhelmed with an unending backlog of basic reporting needs.  Those who successfully manage this backlog are rewarded with an ever expanding repository of dashboards and reports that compete for attention, drowning the data that matters in a sea of noise.\n\nLuca is a radical rethink of analytics for subscriptions business that summarizes the entirety of a business into a handful of KPIs that can be monitored, diagnosed and optimized. Built-in ML and simulation models allowing users to drill into concerning areas and project the impact of interventions in a single gesture.  Built in collaboration and integration into Slack, Microsoft Teams and the Google productivity suite enables organizations to effectively translate to action.\n\nGetting started with Luca is simple.  Luca connects the leading CRM and marketing automation platforms to power its models and KPIs. Users will be able to see the analytics Luca provides hours within connecting the system - no analyst, data scientist or report developer required. Organizations can optionally leverage Luca’s open API to connect supplementary data to enhance the model with additional data to strengthen the model.\n\n“Like so many others across our market, we’re in the middle of a subscription transformation.” says Melissa Doug, CFO of Intiu. “This is the biggest change we have in our business model in our 30 year history and is forcing us to rethink how we run our business.  We are looking to data to guide our decision-making in this new world, but our BI team is already overwhelmed with our backlog of analytic needs for our existing transactional business.  Luca has been a revelation. The built-in one-click diagnostics has made it gut-driven decisions inexcusable.  I was sold when the system automatically identified that a sharp decrease in our MQLs in the NE region was the reason for our improved pipeline coverage.

        "evidence": "A circular economy (also referred to as circularity and CE) is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products for as long as possible. CE aims to tackle global challenges such as climate change, biodiversity loss, waste, and pollution by emphasizing the design-based implementation of the three base principles of the model. The three principles required for the transformation to a circular economy are: eliminating waste and pollution, circulating products and materials, and the regeneration of nature. CE is defined in contradistinction to the traditional linear economy. The idea and concepts of circular economy (CE) have been studied extensively in academia, business, and government over the past ten years. CE has been gaining popularity because it helps to minimize emissions and consumption of raw materials, open up new market prospects and principally, increase the sustainability of consumption and improve resource efficiency.\n\nAt a government level, CE is viewed as means of combating global warming as well as a facilitator of long-term growth. CE may geographically connect actors and resources to stop material loops at the regional level. In its core principle, the European Parliament defines CE as, “a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended.”\n\nIn a linear economy, natural resources are turned into products that are ultimately destined to become waste because of the way they have been designed and manufactured. This process is often summarized by \"take, make, waste\". By contrast, a circular economy employs reuse, sharing, repair, refurbishment, remanufacturing and recycling to create a closed-loop system, reducing the use of resource inputs and the creation of waste, pollution and carbon emissions. The circular economy aims to keep products, materials, equipment and infrastructure in use for longer, thus improving the productivity of these resources. Waste materials and energy should become input for other processes through waste valorization: either as a component for another industrial process or as regenerative resources for nature (e.g., compost). The Ellen MacArthur Foundation (EMF) defines the circular economy as an industrial economy that is restorative or regenerative by value and design.",
        "answer": "A circular economy focuses on the principles of eliminating waste and pollution, circulating products and materials, and the regeneration of nature. In contrast, most capitalistic economies are called \"linear\" in that raw materials are turned into products which are eventually discarded. While a circular economy focuses on sustainable consumption on an Earth with limited resources, linear economies like the USA's implicitly assume a never-ending supply of raw material inputs.",

I do believe McDonald’s disappearance would have some difference in some communities in the short term since there are 210,000 people working at McDonald’s. And also, it can have environmental, and medical benefits that can make the world a better place.\n    The world is hugely affected by McDonald’s action, which makes the disappearance of McDonald’s could make the world a better place although it could have some negative influence on equality and education. Although McDonald's helps organizations that help people who lack education, suffer in poverty, or fight against discrimination, the positive impact of McDonald’s departure makes the world a better place. For example, since McDonald’s cut down the forest to build a cow farm, it can cause deforestation that is threatening the ecosystem and animal habitats. In addition, McDonald’s produces 2 million tons of packaging each year. This means that the retirement of McDonald’s could prevent habitat loss, deforestation, and even waste problems and have a huge, positive impact on the environment.\n    However, the change in McDonald's retirement causes would vary between different stakeholders, but overall, it would only have a mild, or little difference between people’s lives. Although McDonald’s disappearance might shock many people, after a short term, the other fast-food restaurants would replace McDonald’s, so fast-food lovers could adapt to the new environment. Furthermore, although 210,000 people could lose their job, it is still possible for them to change to another job, or have an opportunity to change into another job that they have an interest in. Therefore, McDonald’s disappearance could have little or no difference at all to some people, and withdraw from all the honorable accomplishments.\n    In conclusion, I think that the disappearance of McDonald’s can make the world a better place for environmental, and medical reasons although it could have negative effects in some communities, and that McDonald’s would not be forgotten by the joy and honorable achievements that they have achieved in the last few years.",

        "evidence": "Deep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available. However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents.",

        "evidence": "For the purposes of this paper, we focused on matching accounts between two of the largest social networks: Twitter and Facebook. In order to proceed with our study, we needed a sizeable (few thousand) number of English speaking users with accounts on both Twitter and Facebook. We also needed to know the precise matching between the Twitter and Facebook accounts for our ground truth.\nTo that end, we crawled publicly available, English-language, Google Plus accounts using the Google Plus API and scraped links to the users' other social media profiles. (Note that one of the reasons why we used Twitter and Facebook is that they were two of the most common sites linked to on Google Plus). We used a third party social media site (i.e., Google Plus), one that was not used in our analysis to compile our ground truth in order to limit selection bias in our data collection.\nWe discarded all users who did not link to an account for both Twitter and Facebook and those whose accounts on either of these sites were not public. We then used the APIs of Twitter and Facebook to collect posts made by the users on these sites. We only collected the linguistic content and the date and time at the which the posts were made. For technical and privacy reasons, we did not collect any information from the profile of the users, such as the location, screen name, or birthday.\nOur analysis focused on activity of users for one whole year, from February 1st, 2014 to February 1st, 2015. Since we can not reliably model the behaviour patterns of users with scarce data, users with less than 20 posts in that time period on either site were discarded. Overall, we collected a dataset of $5,612$ users with each having a Facebook and Twitter account for a total of $11,224$ accounts.\nFigure 1 shows the distribution of the number of posts per user for Twitter and Facebook for our collected dataset. In the figure, the data for the number of posts has been divided into 500 bins. For the Twitter data, each bin corresponds to 80 tweets, while for the Facebook data, it corresponds to 10 posts.

The ambiguous pronoun is `it'. The two antecedents are `trophy' and `brown suitcase'. A human reader will naturally interpret `it' as referring to the trophy in the first sentence and to the suitcase in the second sentence, using the world knowledge that a small object can fit in a large container, but a large object cannot fit in a small container (Davis 2013). Condition 4 is satisfied because either a trophy or a suitcase can be either large or small, and there is no reason to suppose that there would be a meaningful correlation of `small' or `large' with `trophy' or `suitcase' in a typical corpus.\nWe will say that an element of a Winograd schema is “solved” if the referent of the pronoun is identified.\nAn example of a pair of sentences satisfying conditions 1-3 but not 4 would be\nSince women cannot be carcinogenic and pills cannot be pregnant, the pronoun `they' in these sentences is easily disambiguated using selectional restrictions.

The correct resolution of the pronoun is different in the two sentences. 4.

        "answer": "A module easily attachable to a sequence-to-sequence model that transforms a list of entities into a vector representation of the topic of the summary.",
        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nE2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector.",

        "answer": "It is a simple method based on bidirectional LSTMs.",
        "evidence": "Encoding of words is perhaps the most important step towards a successful end-to-end natural language processing application. Although word embeddings have been shown to provide benefit to such models, they commonly treat words as the smallest meaning bearing unit and assume that each word type has its own vector representation. This assumption has two major shortcomings especially for languages with rich morphology: (1) inability to handle unseen or out-of-vocabulary (OOV) word-forms (2) inability to exploit the regularities among word parts. The limitations of word embeddings are particularly pronounced in sentence-level semantic tasks, especially in languages where word parts play a crucial role. Consider the Turkish sentences “Köy+lü-ler (villagers) şehr+e (to town) geldi (came)” and “Sendika+lı-lar (union members) meclis+e (to council) geldi (came)”. Here the stems köy (village) and sendika (union) function similarly in semantic terms with respect to the verb come (as the origin of the agents of the verb), where şehir (town) and meclis (council) both function as the end point. These semantic similarities are determined by the common word parts shown in bold. However ortographic similarity does not always correspond to semantic similarity. For instance the ortographically similar words knight and night have large semantic differences. Therefore, for a successful semantic application, the model should be able to capture both the regularities, i.e, morphological tags and the irregularities, i.e, lemmas of the word.\nMorphological analysis already provides the aforementioned information about the words. However access to useful morphological features may be problematic due to software licensing issues, lack of robust morphological analyzers and high ambiguity among analyses. Character-level models (CLM), being a cheaper and accessible alternative to morphology, have been reported as performing competitively on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 . However the extent to which these tasks depend on morphology is small; and their relation to semantics is weak. Hence, little is known on their true ability to reveal the underlying morphological structure of a word and their semantic capabilities. Furthermore, their behaviour across languages from different families; and their limitations and strengths such as handling of long-range dependencies, reaction to model complexity or performance on out-of-domain data are unknown. Analyzing such issues is a key to fully understanding the character-level models.\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:\n $[$ Villagers $]$ comers came $[$ to town $]$ end point\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis. The gold morphology serves as the upper bound for us to compare and analyze the performances of character-level models on languages of varying morphological typologies. We carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology. In regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English. Our experiments and analysis reveal insights such as:\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis.",

        "evidence": "Author profiling is the characterization of an author through some key attributes such as gender, age, and language. It's an indispensable task especially in security, forensics, and marketing. Recently, social media has become a great data source for the potential learning approaches. Furthermore, gender prediction has been a popular profiling task.\nThe traditional approach to gender prediction problem is extracting a useful set of hand-crafted features and then feeding them into a standard classification algorithm. In their study, BIBREF0 work with the style-based features of message length, stop word usage, frequency of smiley etc. and use different classifiers such as k-nearest neighbor, naive bayes, covering rules, and backpropagation to predict gender on chat messages. Similarly, BIBREF1 select some hand-crafted features and feed them into various classifiers.\nMost of the work on gender prediction rely on n-gram features BIBREF2. BIBREF3 give Latent Semantic Analysis (LSA)-reduced forms of word and character n-grams into Support Vector Machine (SVM) and achieve state-of-the-art performance. Apart from exploiting n-gram frequencies, there are studies BIBREF4, BIBREF5, BIBREF6 to extract cross-lingual features to determine gender from tweets. Some other work BIBREF4, BIBREF7 exploit user metadata besides using just tweets.\nRecently, neural network-based models have been proposed to solve this problem. Rather than explicitly extracting features, the aim is to develop an architecture that implicitly learns. In author profiling, both style and content-based features were proved useful BIBREF8 and neural networks are able to capture both syntactic and semantic regularities. In general, syntactic information is drawn from the local context. On the other hand, semantic information is often captured with larger window sizes. Thus, CNNs are preferred to obtain style-based features while RNNs are the methods of choice for addressing content-based features BIBREF9. In literature, CNN BIBREF10 or RNN BIBREF11, BIBREF12, BIBREF13 is used on this task. BIBREF11 obtain state-of-the-art performance among neural methods by proposing a model architecture where they process text through RNN with GRU cells. Also, the presence of an attention layer is shown to boost the performance of neural methods BIBREF11, BIBREF10.\nIn this work, we propose a model that relies on RNN with attention mechanism (RNNwA). A bidirectional RNN with attention mechanism both on word level and tweet level is trained with word embeddings. The final representation of the user is fed to a fully connected layer for prediction. Since combining some hand-crafted features with a learned linear layer has shown to perform well in complex tasks like Semantic Role Labeling (SRL) BIBREF14, an improved version of the model (RNNwA + n-gram) is also tested with hand-crafted features. In the improved version, LSA-reduced n-gram features are concatenated with the neural representation of the user. Then the result is fed into a fully-connected layer to make prediction. Models are tested in three languages; English, Spanish, and Arabic, and the improved version achieves state-of-the-art accuracy on English, and competitive results on Spanish and Arabic corpus.\nThere are many datasets created for this task BIBREF15, BIBREF16. In this work, we have used the dataset and benchmarks provided by the PAN 2018 shared task on author profiling BIBREF15. As the dataset contains a constant number of 100 tweets per user, accuracy tests are performed both on user and tweet level (tweet-level predictions are made by removing the user-level attention). Tweet-level accuracy tests show interesting results during hyperparameter optimization. When the tweet-level predictions are averaged to produce user-level predictions, it is seen that the hyperparameters that gave the best results in terms of tweet-level accuracy, performs worse in user-level accuracy. The better user-level models, with different hyperparameters, that gave the highest user-level accuracy are observed to slightly overfit on tweet-level. It leads us to believe that the overfitting in the tweet-level predictions in best user-level models acts similar to an attention mechanism by over-emphasizing some distinctive tweets and ignoring the rest.\nIn this work, we have used the dataset and benchmarks provided by the PAN 2018 shared task on author profiling.",

        "evidence": "Indiana Jones is an American media franchise based on the adventures of Dr. Henry Walton \"Indiana\" Jones, Jr., a fictional professor of archaeology, that began in 1981 with the film Raiders of the Lost Ark. In 1984, a prequel, The Temple of Doom, was released, and in 1989, a sequel, The Last Crusade. A fourth film followed in 2008, titled The Kingdom of the Crystal Skull. A fifth and final film, titled The Dial of Destiny, is in production and is scheduled to be released in 2023. The series was created by George Lucas and stars Harrison Ford as Indiana Jones. The first four films were directed by Steven Spielberg, who worked closely with Lucas during their production.\n\nIn 1992, the franchise expanded to a television series with The Young Indiana Jones Chronicles, portraying the character in his childhood and youth, and including adventures with his parents.\n\nMarvel Comics began publishing The Further Adventures of Indiana Jones in 1983, and Dark Horse Comics gained the comic book rights to the character in 1991. Novelizations of the films have been published, as well as many novels with original adventures, including a series of German novels by Wolfgang Hohlbein, twelve novels set before the films published by Bantam Books, and a series set during the character's childhood inspired by the television show.\n\nNumerous Indiana Jones video games have been released since 1982.\n\nBackground\nDuring 1973, George Lucas wrote The Adventures of Indiana Smith. Like Star Wars, it was an opportunity to create a modern version of the movie serials of the 1930s and 1940s. Lucas discussed the concept with Philip Kaufman, who worked with him for several weeks and decided upon the Ark of the Covenant as the MacGuffin. The project was stalled when Clint Eastwood hired Kaufman to write The Outlaw Josey Wales. In May 1977, Lucas was in Maui, trying to escape the worldwide success of Star Wars. His friend and colleague Steven Spielberg was also there, on vacation from work on Close Encounters of the Third Kind. Spielberg told Lucas he was interested in making a James Bond film, but Lucas told him of an idea \"better than James Bond\", outlining the plot of Raiders of the Lost Ark. Spielberg loved it, calling it \"a James Bond film without the hardware\", and had the character's surname changed to Jones. Spielberg and Lucas made a deal with Paramount Pictures for five Indiana Jones films.\n\nSpielberg and Lucas aimed to make Indiana Jones and the Temple of Doom much darker, because of their personal moods following their respective breakups and divorces. Lucas made the film a prequel as he did not want the Nazis to be the villains again. He had ideas regarding the Monkey King and a haunted castle, but eventually created the Sankara Stones, that would be used in the film. He hired Willard Huyck and Gloria Katz to write the script as he knew of their interest in Indian culture. The major scenes that were dropped from Raiders of the Lost Ark were included in this film: an escape using a giant rolling gong as a shield, a fall out of a plane in a raft, and a mine cart chase. For the third film, Spielberg revisited the Monkey King and haunted castle concepts, before Lucas suggested the Holy Grail. Spielberg had previously rejected this as too ethereal, but then devised a father-son story and decided that \"The Grail that everybody seeks could be a metaphor for a son seeking reconciliation with a father and a father seeking reconciliation with a son.\"\n\nFollowing the 1989 release of Indiana Jones and the Last Crusade, Lucas let the series end as he felt he could not think of a good plot device to drive the next installment and chose instead to produce The Young Indiana Jones Chronicles, which explored the character in his early years. Ford played Indiana in one episode, narrating his adventures in 1920 Chicago. When Lucas shot Ford's role in December 1992, he realized that the scene opened up the possibility of a film with an older Indiana set in the 1950s. The film could reflect a science fiction 1950s B-movie, with aliens as the plot device. Ford disliked the new angle, telling Lucas: \"No way am I being in a Steven Spielberg movie like that.\" Spielberg himself, who depicted aliens in Close Encounters of the Third Kind and E.T. the Extra-Terrestrial, resisted it. Lucas devised a story, which Jeb Stuart turned into a script from October 1993 to May 1994. Lucas wanted Indiana to get married, which would allow Henry Jones Sr. to return, expressing concern over whether his son is happy with what he has accomplished. After learning that Joseph Stalin was interested in psychic warfare, Lucas decided to have Russians as the villains and the aliens to have psychic powers. Following Stuart's next draft, Lucas hired Last Crusade writer Jeffrey Boam to write the next three versions, the last of which was completed in March 1996. Three months later, Independence Day was released, and Spielberg told Lucas he would not make another alien invasion film (or at least not until War of the Worlds in 2005). Lucas decided to focus on the Star Wars prequels instead.\n\nIn 2000, Spielberg's son asked when the next Indiana Jones film would be released, which made him interested in reviving the project. The same year, Ford, Lucas, Spielberg, Frank Marshall, and Kathleen Kennedy met during the American Film Institute's tribute to Ford, and decided they wanted to enjoy the experience of making an Indiana Jones film again. Spielberg also found returning to the series a respite from his many dark films during this period. Spielberg and Lucas discussed the central idea of a B-movie involving aliens, and Lucas suggested using crystal skulls to ground the idea. Lucas found these artifacts as fascinating as the Ark, and had intended to feature them for a Young Indiana Jones episode before the show's cancellation. M. Night Shyamalan was hired to write for an intended 2002 shoot, but he was overwhelmed by the task, and claimed it was difficult to get Ford, Spielberg, and Lucas to focus. Stephen Gaghan and Tom Stoppard were also approached.\n\nFrank Darabont, who wrote various Young Indiana Jones episodes, was hired to write in May 2002. His script, titled Indiana Jones and the City of Gods, was set in the 1950s, with ex-Nazis pursuing Jones. Spielberg conceived the idea because of real-life figures such as Juan Perón in Argentina, who allegedly protected Nazi war criminals. Darabont claimed Spielberg loved the script, but Lucas had issues with it, and decided to take over writing himself. Lucas and Spielberg acknowledged that the 1950s setting could not ignore the Cold War, and the Russians were more plausible villains. Spielberg decided he could not satirize the Nazis after directing Schindler's List, while Ford felt \"We plum wore the Nazis out.\" Darabont's main contribution was reintroducing Marion Ravenwood as Indiana's love interest, but he gave them a 13-year-old daughter, which Spielberg decided was too similar to The Lost World: Jurassic Park.\n\nJeff Nathanson met with Spielberg and Lucas in August 2004, and turned in the next drafts in October and November 2005, titled The Atomic Ants. David Koepp continued on from there, giving his script the subtitle Destroyer of Worlds, based on the J. Robert Oppenheimer quote. It was changed to Kingdom of the Crystal Skull, as Spielberg found this a more inviting title which actually named the plot device. Koepp wanted to depict the character of Mutt as a nerd, but Lucas refused, explaining he had to resemble Marlon Brando in The Wild One; \"he needs to be what Indiana Jones's father thought of  – the curse returns in the form of his own son – he's everything a father can't stand\". Koepp collaborated with Lawrence Kasdan on the film's \"love dialogue\".\n\nThe Walt Disney Company has owned the Indiana Jones intellectual property since its acquisition of Lucasfilm, the series' production company, in 2012, when Lucas sold it for $4 billion. Walt Disney Studios owns the distribution and marketing rights to future Indiana Jones films since 2013, with Paramount retaining the distribution rights to the first four films and receiving \"financial participation\" from any additional films. Disney will distribute the fifth film Indiana Jones and the Dial of Destiny, which will be directed by James Mangold and produced by Spielberg.\n\nRaiders of the Lost Ark (1981)\nMain article: Raiders of the Lost Ark\nThe first film is set in 1936. Indiana Jones (Harrison Ford) is hired by government agents to locate the Ark of the Covenant, the gold plated chest containing the stone tablets Moses used to inscribe the Ten Commandments before the Nazi Germans steal it for themselves. The Nazis have teams searching for religious artefacts, including the Ark, which is rumored to make an army that carries the Ark before it invincible. The Nazis are being helped by Indiana's arch-rival and French archaeologist René Belloq (Paul Freeman). With the help of his former lover and tough bar owner Marion Ravenwood (Karen Allen) and his excavator friend Sallah (John Rhys-Davies), Indiana manages to recover the Ark in Egypt. The Nazis steal the Ark and capture Indiana and Marion. Belloq and the Nazis perform a ceremony to open the Ark, but when they do so, all they find inside is sand. Suddenly, spirits come out of the Ark and the Nazis are all killed by the Ark's wrath. Indiana and Marion, who survived by closing their eyes, manage to get the Ark to the United States, where it is stored in a secret government warehouse.\n\nIndiana Jones and the Temple of Doom (1984)\nMain article: Indiana Jones and the Temple of Doom\nThe second film is a prequel set in 1935, a year before Raiders of the Lost Ark. Indiana escapes Chinese gangsters led by Lao Che with the help of singer/actress Willie Scott (Kate Capshaw) and his twelve-year-old sidekick Short Round (Ke Huy Quan). The trio crash-land in India, where they come across a Punjabi village whose children have been kidnapped. The Thuggee cult led by Mola Ram (Amrish Puri) has also taken the holy Sankara Stones, which they will use to take over the world. Indiana manages to overcome Mola Ram's evil power, rescues the children and returns the stones to their rightful place, overcoming his own mercenary nature. The film has been noted as an outlier in the franchise, as it does not feature Indy's university or any antagonistic political entity, and is less focused on archaeology, being presented as a dark movie with gross-out elements, human sacrifice and torture.\n\nIndiana Jones and the Last Crusade (1989)\nMain article: Indiana Jones and the Last Crusade\nThe third film is set in 1938. Indiana and his friend Marcus Brody (Denholm Elliott) are assigned by American businessman Walter Donovan (Julian Glover) to find the Holy Grail. They are teamed up with Dr. Elsa Schneider (Alison Doody), following on from where Indiana's estranged father Henry (Sean Connery) left off before he disappeared. It transpires that Donovan and Elsa are in league with the Nazis, who captured Henry Jones in order to get Indiana to help them find the Grail. However, Indiana recovers his father's diary filled with his research, and manages to rescue him before finding the location of the Grail. Both Donovan and Elsa fall to the temptation of the Grail, while Indiana and Henry realize that their relationship with each other is more important than finding the relic.\n\nIndiana Jones and the Kingdom of the Crystal Skull (2008)\nMain article: Indiana Jones and the Kingdom of the Crystal Skull\nThe fourth film is set in 1957, nineteen years after The Last Crusade. Indiana is having a quiet life teaching before being thrust into a new adventure. He races against agents of the Soviet Union, led by Irina Spalko (Cate Blanchett) for a crystal skull. His journey takes him across Nevada, Connecticut, Peru, and the Amazon rainforest in Brazil. Indiana is faced with betrayal by one of his best friends, Mac (Ray Winstone), is introduced to a greaser named Mutt Williams (Shia LaBeouf), who turns out to be his son (his real name revealed to be Henry Jones III), and is reunited with, and eventually marries, Marion Ravenwood, who was the lead female character introduced in the first movie.\n\nIndiana Jones and the Dial of Destiny (2023)\nMain article: Indiana Jones and the Dial of Destiny\nA fifth film, set in 1969, is scheduled for release on June 30, 2023. The film is being directed by James Mangold, who wrote the script with Jez and John-Henry Butterworth. Spielberg was initially set to direct the film, before passing it to Mangold. Spielberg instead serves as a producer, along with Kennedy and Marshall. Ford reprises the title role, and new cast members include Phoebe Waller-Bridge, Mads Mikkelsen, Thomas Kretschmann, Boyd Holbrook, Shaunette Renée Wilson, Toby Jones and Antonio Banderas. Development of the film began in 2008, but the project stalled for years. Filming eventually began in the United Kingdom in June 2021 and wrapped in February 2022.",

The use of government revenue expenditures to influence macroeconomic variables developed in reaction to the Great Depression of the 1930s, when the previous laissez-faire approach to economic management became unworkable. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorised that government changes in the levels of taxation and government spending influence aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target inflation (which is considered \"healthy\" at the level in the range 2%–3%) and to increase employment. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilise the economy over the course of the business cycle.\n\nChanges in the level and composition of taxation and government spending can affect macroeconomic variables, including:\n\naggregate demand and the level of economic activity\nsaving and investment\nincome distribution\nallocation of resources.\nFiscal policy can be distinguished from monetary policy, in that fiscal policy deals with taxation and government spending and is often administered by a government department; while monetary policy deals with the money supply, interest rates and is often administered by a country's central bank.

Although both approaches perform similarly, they differ in the way how the decision criterion INLINEFORM1 is determined. While COAV requires a training corpus to learn INLINEFORM2 , Caravel assumes that the given test corpus (which provides the impostors) is balanced. Given this assumption, Caravel first computes similarity scores for all verification problems in the corpus and then sets INLINEFORM3 to the median of all similarities (cf. Figure FIGREF49 ). Thus, from a machine learning perspective, there is some undue training on the test set.

        "evidence": "Using GANs, we can train generative models in a two-player game setting between a discriminator and a generator, where the discriminator (a binary classifier) learns to distinguish between real and fake data samples and the generator tries to fool the discriminator by generating authentic and high quality output BIBREF16. GANs have shown to be successful in image generation tasks BIBREF17 and recently, some progress has been observed in text generation BIBREF13, BIBREF12, BIBREF15. Our generator is a language model trained using backpropagation through time BIBREF18. During the pre-training phase we optimize for MLE and during the GAN training phase, we optimize on the creativity reward from the discriminator. The discriminator's encoder has the same architecture as the generator encoder module with the addition of a pooled decoder layer. The decoder contains 3 $[Dense Batch Normalization,ReLU]$ blocks and an addtional $Sigmoid$ layer. The discriminator decoder takes the hidden state at the last time step of a sequence concatenated with both the max-pooled and mean-pooled representation of the hidden states BIBREF19 and outputs a number in the range $[0,1]$. The difficulty of using GANs in text generation comes from the discrete nature of text, making the model non-differentiable hence, we update parameters for the generator model with policy gradients as described in Yu BIBREF15.\nWe utilize AWD-LSTM BIBREF20 and TransformerXL BIBREF21 based language models. For model hyperparameters please to refer to Supplementary Section Table TABREF5. We use Adam optimizer BIBREF22 with $\\beta 1= 0.7$ and $\\beta 2= 0.8$ similar to BIBREF19 and use a batch size of 50. Other practices for LM training were the same as BIBREF21 and BIBREF20 for Transformer-XL and AWD-LSTM respectively. We refer to our proposed GAN as Creative-GAN and compare it to a baseline (a language model equivalent to our pre-trained generator) and a GumbelGAN model BIBREF14 across all proposed datasets. We use three creative English datasets with distinct linguistic characteristics: (1) A corpus of 740 classical and contemporary English poems, (2) a corpus of 14950 metaphor sentences retrieved from a metaphor database website and (3) a corpus of 1500 song lyrics ranging across genres. The mix of linguistic styles within this corpus offers the potential for interesting variation during the generation phase. We use the same pre-processing as in earlier work BIBREF19, BIBREF23. We reserve 10% of our data for test set and another 10% for our validation set.\nWe first pre-train our generator on the Gutenberg dataset BIBREF24 for 20 epochs and then fine-tune BIBREF19 them to our target datasets with a language modeling objective. The discriminator's encoder is initialized to the same weights as our fine-tuned language model. Once we have our fine-tuned encoders for each target dataset, we train in an adversarial manner. The discriminator objective here is to score the quality of the creative text. The discriminator is trained for 3 iterations for every iteration of the generator, a practice seen in previous work BIBREF25. Creative-GAN relies on using the reward from the discriminator BIBREF12, BIBREF15 for backpropagation. We follow a similar training procedure for GumbelGAN. Outputs are generated through sampling over a multinomial distribution for all methods, instead of $argmax$ on the log-likelihood probabilities, as sampling has shown to produce better output quality BIBREF4. Please refer to Supplementary Section Table TABREF6 for training parameters of each dataset and Table TABREF5 for hyperparameters of each encoder. We pick these values after experimentation with our validation set. Training and output generation code can be found online.\nWe use Adam optimizer [23] with β1 = 0.7 and β2 = 0.8 similar to [20] and use a batch size of 50.",

        "question": "What is previous work lacking？",
        "answer": "They lack a clear definition of cyberbullying.",
        "evidence": "Many social and psychological studies have worked towards a definition of cyberbullying. A common starting point for conceptualising cyberbullying are definitions of traditional (or offline) bullying. Seminal work has been published by BIBREF23 , BIBREF24 , BIBREF25 , BIBREF26 , who describe bullying based on three main criteria, including i) intention (i.e., a bully intends to inflict harm on the victim), ii) repetition (i.e., bullying acts take place repeatedly over time) and iii) a power imbalance between the bully and the victim (i.e., a more powerful bully attacks a less powerful victim). With respect to cyberbullying, a number of definitions are based on the above-mentioned criteria. A popular definition is that of BIBREF21 which describes cyberbullying as “an aggressive, intentional act carried out by a group or individual, using electronic forms of contact, repeatedly and over time, against a victim who cannot easily defend him or herself”.\nNevertheless, some studies have underlined the differences between offline and online bullying, and have therefore questioned the relevance of the three criteria to the latter. Besides theoretical objections, a number of practical limitations have been observed. Firstly, while BIBREF23 claims intention to be inherent to traditional bullying, this is much harder to ascertain in an online environment. Online conversations lack the signals of a face-to-face interaction like intonation, facial expressions and gestures, which makes them more ambiguous than real-life conversations. The receiver may therefore get the wrong impression that they are being offended or ridiculed BIBREF19 . Another criterion for bullying that might not hold in online situations, is the power imbalance between bully and victim. Although this can be evident in real life (e.g. the bully is larger, stronger, older than the victim), it is hard to conceptualise or measure in an online environment. It may be related to technological skills, anonymity or the inability of the victim to get away from the bullying BIBREF27 , BIBREF17 , BIBREF28 . Empowering for the bully are also inherent characteristics of the Web: once defamatory or confidential information about a person is made public through the Internet, it is hard, if not impossible, to remove.\nFinally, while arguing that repetition is a criterion to distinguish cyberbullying from single acts of aggression, BIBREF23 himself states that such a single aggressive action can be considered bullying under certain circumstances, although it is not entirely clear what these circumstances involve. Accordingly, BIBREF27 claim that repetition in cyberbullying is problematic to operationalise, as it is unclear what the consequences are of a single derogatory message on a public page. A single act of aggression or humiliation may result in continued distress and humiliation for the victim if it is shared or liked by multiple perpetrators or read by a large audience. BIBREF29 compare this with a `snowball effect': one post may be repeated or distributed by other people so that it becomes out of the control of the initial bully and has larger effects than was originally intended.\nGiven these arguments, a number of less `strict' definitions of cyberbullying were postulated by among others BIBREF6 , BIBREF5 , BIBREF1 , where a power imbalance and repetition are not deemed necessary conditions for cyberbullying.\nThe above paragraphs demonstrate that defining cyberbullying is far from trivial, and varying prevalence rates (cf. Section SECREF1 ) confirm that a univocal definition of the phenomenon is still lacking in the literature BIBREF1 . Based on existing conceptualisations, we define cyberbullying as content that is published online by an individual and that is aggressive or hurtful against a victim. Based on this definition, an annotation scheme was developed (see BIBREF30 ) to signal textual characteristics of cyberbullying, including posts from bullies, as well as reactions by victims and bystanders.\nNevertheless, some studies have underlined the differences between offline and online bullying, and have therefore questioned the relevance of the three criteria to the latter.",

        "question": "Based on the reference text, provide a concise overview of the main objectives of the Federal Reserve",
        "evidence": "The Federal Reserve System (often shortened to the Federal Reserve, or simply the Fed) is the central banking system of the United States. It was created on December 23, 1913, with the enactment of the Federal Reserve Act, after a series of financial panics (particularly the panic of 1907) led to the desire for central control of the monetary system in order to alleviate financial crises.[list 1] Over the years, events such as the Great Depression in the 1930s and the Great Recession during the 2000s have led to the expansion of the roles and responsibilities of the Federal Reserve System.\n\nCongress established three key objectives for monetary policy in the Federal Reserve Act: maximizing employment, stabilizing prices, and moderating long-term interest rates. The first two objectives are sometimes referred to as the Federal Reserve's dual mandate. Its duties have expanded over the years, and currently also include supervising and regulating banks, maintaining the stability of the financial system, and providing financial services to depository institutions, the U.S. government, and foreign official institutions. The Fed also conducts research into the economy and provides numerous publications, such as the Beige Book and the FRED database.\n\nThe Federal Reserve System is composed of several layers. It is governed by the presidentially-appointed board of governors or Federal Reserve Board (FRB). Twelve regional Federal Reserve Banks, located in cities throughout the nation, regulate and oversee privately-owned commercial banks. Nationally chartered commercial banks are required to hold stock in, and can elect some board members of, the Federal Reserve Bank of their region.\n\nThe Federal Open Market Committee (FOMC) sets monetary policy. It consists of all seven members of the board of governors and the twelve regional Federal Reserve Bank presidents, though only five bank presidents vote at a time—the president of the New York Fed and four others who rotate through one-year voting terms. There are also various advisory councils.[list 2] It has a structure unique among central banks, and is also unusual in that the United States Department of the Treasury, an entity outside of the central bank, prints the currency used.\n\nThe federal government sets the salaries of the board's seven governors, and it receives all the system's annual profits, after dividends on member banks' capital investments are paid, and an account surplus is maintained. In 2015, the Federal Reserve earned a net income of $100.2 billion and transferred $97.7 billion to the U.S. Treasury, and 2020 earnings were approximately $88.6 billion with remittances to the U.S. Treasury of $86.9 billion. Although an instrument of the U.S. government, the Federal Reserve System considers itself \"an independent central bank because its monetary policy decisions do not have to be approved by the president or by anyone else in the executive or legislative branches of government, it does not receive funding appropriated by Congress, and the terms of the members of the board of governors span multiple presidential and congressional terms.\"",

        "question": "By training on the new dataset, what results does the authoes achieve?",
        "answer": "Reducing the prediction error by almost one third.",
        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nBy training on the new dataset, we reduce the prediction error by almost one third.",

        "evidence": "Our framework combines text-embedding, geometric graph construction and multi-resolution community detection to identify, rather than impose, content-based clusters from free, unstructured text in an unsupervised manner.\nFigure 1 shows a summary of our pipeline. First, we pre-process each document to transform text into consecutive word tokens, where words are in their most normalised forms, and some words are removed if they have no distinctive meaning when used out of context BIBREF5 , BIBREF6 . We then train a paragraph vector model using the Document to Vector (Doc2Vec) framework BIBREF7 on the whole set (13 million) of preprocessed text records, although training on smaller sets (1 million) also produces good results. This training step is only done once. This Doc2Vec model is subsequently used to infer high-dimensional vector descriptions for the text of each of the 3229 documents in our target analysis set. We then compute a matrix containing pairwise similarities between any pair of document vectors, as inferred with Doc2Vec. This matrix can be thought of as a full, weighted graph with documents as nodes and edges weighted by their similarity. We sparsify this graph to the union of a minimum spanning tree and a k-Nearest Neighbors (MST-kNN) graph BIBREF8 , a geometric construction that removes less important similarities but preserves global connectivity for the graph and, hence, for the dataset. The derived MST-kNN graph is analysed with Markov Stability BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , a multi-resolution dynamics-based graph partitioning method that identifies relevant subgraphs (i.e., clusters of documents) at different levels of granularity. MS uses a diffusive process on the graph to reveal the multiscale organisation at different resolutions without the need for choosing a priori the number of clusters, scale or organisation. To analyse a posteriori the different partitions across levels of resolution, we use both visualisations and quantitative scores. The visualisations include word clouds to summarise the main content, graph layouts, as well as Sankey diagrams and contingency tables that capture the correspondences across levels of resolution and relationships to the hand-coded classifications. The partitions are also evaluated quantitatively to score: (i) their intrinsic topic coherence (using pairwise mutual information BIBREF13 , BIBREF14 ), and (ii) their similarity to the operator hand-coded categories (using normalised mutual information BIBREF15 ). We now expand on the steps of the computational framework.\nWe benchmarked the Doc2Vec models by scoring how well the document vectors represent the semantic topic structure: (i) calculating centroids for the 15 externally hand-coded categories;  (ii)selecting the 100 nearest reports for each centroid;  (iii) counting the number of incident reports (out of 1500) correctly assigned to their centroid.",

        "question": "Are pre-trained language models highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner?",
        "answer": "Yes.",
        "evidence": "It is common knowledge in modern NLP that using large amounts of high-quality training data is a key aspect in building successful machine-learning based systems. For this reason, a major challenge when building such systems is obtaining data in the domain of interest. But what defines a domain? Natural language varies greatly across topics, styles, levels of formality, genres and many other linguistic nuances BIBREF0, BIBREF1, BIBREF2. This overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impossible to well-define the exact requirements from such data with respect to all the aforementioned aspects. On top of that, domain labels are usually unavailable – e.g. in large-scale web-crawled data like Common Crawl which was recently used to train state-of-the-art pretrained language models for various tasks BIBREF3.\nDomain data selection is the task of selecting the most appropriate data for a domain from a large corpus given a smaller set of in-domain data BIBREF4, BIBREF5, BIBREF6, BIBREF7. In this work, we propose to use the recent, highly successful self-supervised pre-trained language models, e.g. devlin-etal-2019-bert,liu2019roberta for domain data selection. As pretrained LMs demonstrate state-of-the-art performance across many NLP tasks after being trained on massive amounts of data, we hypothesize that the robust representations they learn can be useful for mapping sentences to domains in an unsupervised, data-driven approach. We show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering. We then propose methods to leverage these emergent domain clusters for domain data selection in two ways:\nVia distance-based retrieval in the sentence embedding space induced by the pretrained language model.\nBy fine-tuning the pretrained language model for binary classification, where positive examples are from the domain of interest.\nOur methods enable to select relevant data for the task while requiring only a small set of monolingual in-domain data. As they are based solely on the representations learned by self-supervised LMs, they do not require additional domain labels which are usually vague and over-simplify the notion of domain in textual data. We evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8. Our data selection methods enable to train NMT models that outperform those trained using the well-established cross-entropy difference method of BIBREF4 across five diverse domains, achieving a recall of more than 95% in all cases with respect to an oracle that selects the “true” in-domain data.\nOur contributions in this work are as follows. First, we show that pre-trained language models are highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner. Second, we propose methods to select in-domain data based on this property using vector-space retrieval and positive-unlabeled fine-tuning of pretrained language models for binary classification. Third, we show the applicability of our proposed data selection methods on a popular benchmark for domain adaptation in machine translation. An additional contribution is a new, improved data split we create for this benchmark, as we point on issues with previous splits used in the literature. The code and data for this work is publicly available. We hope this work will encourage more research on understanding the data landscape in NLP, enabling to “find the right data for the task” in the age of massive models and diverse data sources.\nOur contributions in this work are as follows.

However, neither where coffee was first cultivated nor direct evidence of its consumption prior to the 15th century have been found. Sufi monasteries in Yemen employed coffee as an aid to concentration during prayers. Coffee later spread to the Levant and Persia in the early 16th century; it caused some controversy on whether it was halal in Ottoman and Mamluk society. Coffee arrived in Italy the second half of the 16th century through commercial Mediterranean trade routes, while Central and Eastern Europeans learnt of coffee from the Ottomans. By the mid 17th century, it had reached India and the East Indies. Coffee houses would establish themselves in Western Europe by the late 17th century, especially in England and Germany. One of the earliest cultivations of coffee in the New World was when Gabriel de Clieu brought coffee seedlings to Martinique in 1720. These beans later sprouted 18,680 coffee trees which enabled its spread to other Caribbean islands like Saint-Domingue and also to Mexico. By 1788, Saint-Domingue supplied half the world's coffee. By 1852, globally, Brazil became the largest producer of coffee and has held that status ever since. The period since 1950 saw the widening of the playing field due to the emergence of several other major producers, notably Colombia, Ivory Coast, Ethiopia, and Vietnam; the latter overtook Colombia and became the second-largest producer in 1999. Modern production techniques along with the mass productization of coffee has made it a household item today.",

        "evidence": "With the availability of rich data on users' locations, profiles and search history, personalization has become the leading trend in large-scale information retrieval. However, efficiency through personalization is not yet the most suitable model when tackling domain-specific searches. This is due to several factors, such as the lexical and semantic challenges of domain-specific data that often include advanced argumentation and complex contextual information, the higher sparseness of relevant information sources, and the more pronounced lack of similarities between users' searches.\nA recent study on expert search strategies among healthcare information professionals BIBREF0 showed that, for a given search task, they spend an average of 60 minutes per collection or database, 3 minutes to examine the relevance of each document, and 4 hours of total search time. When written in steps, their search strategy spans over 15 lines and can reach up to 105 lines.\nWith the abundance of information sources in the medical domain, consumers are more and more faced with a similar challenge, one that needs dedicated solutions that can adapt to the heterogeneity and specifics of health-related information.\nDedicated Question Answering (QA) systems are one of the viable solutions to this problem as they are designed to understand natural language questions without relying on external information on the users.\nIn the context of QA, the goal of Recognizing Question Entailment (RQE) is to retrieve answers to a premise question ( INLINEFORM0 ) by retrieving inferred or entailed questions, called hypothesis questions ( INLINEFORM1 ) that already have associated answers. Therefore, we define the entailment relation between two questions as: a question INLINEFORM2 entails a question INLINEFORM3 if every answer to INLINEFORM4 is also a correct answer to INLINEFORM5 BIBREF1 .\nRQE is particularly relevant due to the increasing numbers of similar questions posted online BIBREF2 and its ability to solve differently the challenging issues of question understanding and answer extraction. In addition to being used to find relevant answers, these resources can also be used in training models able to recognize inference relations and similarity between questions.\nQuestion similarity has recently attracted international challenges BIBREF3 , BIBREF4 and several research efforts proposing a wide range of approaches, including Logistic Regression, Recurrent Neural Networks (RNNs), Long Short Term Memory cells (LSTMs), and Convolutional Neural Networks (CNNs) BIBREF5 , BIBREF6 , BIBREF1 , BIBREF7 .\nIn this paper, we study question entailment in the medical domain and the effectiveness of the end-to-end RQE-based QA approach by evaluating the relevance of the retrieved answers. Although entailment was attempted in QA before BIBREF8 , BIBREF9 , BIBREF10 , as far as we know, we are the first to introduce and evaluate a full medical question answering approach based on question entailment for free-text questions.

The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources, and from grey, brown or black hydrogen, which is obtained from fossil sources or from the electrolysis of water. Natural hydrogen may be renewable, non-polluting and allows for lower cost operation compared to industrial hydrogen. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.\n\nOrigin of natural hydrogen\nThere are several sources of natural hydrogen:\n\n- degassing of deep hydrogen from the Earth's crust and mantle;\n- reaction of water with ultrabasic rocks (serpentinisation);\n- contact of water with reducing agents in the Earth's mantle;\n- interaction of water with freshly exposed rock surfaces (weathering);\n- decomposition of hydroxyl ions in the structure of minerals;\n- Natural radiolysis of water;\n- decomposition of organic matter;\n- biological activity\n- Extraction\n- Natural hydrogen is extracted from wells, mixed with other gases such as nitrogen or helium.\n\nSeveral sources have been identified in France. Geologists Alain Prinzhofer and Eric Derville have demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States. However, their potential remains difficult to assess.\n\nNumerous emanations on the ocean floor have been identified but are difficult to exploit. The discovery of a significant emergence in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.\n\nGeology\nNatural hydrogen is generated continuously from a variety of natural sources. There are many known hydrogen emergences on mid-ocean ridges. Another of the known reactions, serpentinisation, occurs under the sea floor (in the oceanic crust).\n\nDiagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably in Russia. Other sources are being explored, such as mantle hydrogen, or hydrogen from radiolysis (natural electrolysis) or from bacterial activity. In France, the Alps and Pyrenees are suitable for exploitation. New Caledonia has hyperalkaline sources that show dihydrogen emissions. A large accumulation of natural hydrogen was discovered in Bourakebougou (Mali).\n\nCharacteristics\nDihydrogen is very soluble in fresh water, especially at depth (solubility increases with pressure).\n\nhttps://en.wikipedia.org/wiki/Natural_hydrogen",

        "evidence": "Common methods that tackle the problem of class imbalance by modifying the data to create balanced datasets are undersampling and oversampling. Undersampling randomly removes instances from the majority class and is only suitable for problems with an abundance of data. Oversampling means creating more minority class instances to match the size of the majority class. Oversampling methods range from simple random oversampling, i.e. repeating the training procedure on instances from the minority class, chosen at random, to the more complex, which involves constructing synthetic minority-class samples. Random oversampling is similar to cost-sensitive learning as repeating the sample several times makes the cost of its mis-classification grow proportionally. Kolomiyets et al. kolomiyets2011model, Zhang et al. zhang2015character, and Wang and Yang wang2015s perform data augmentation using synonym replacement, i.e. replacing random words in sentences with their synonyms or nearest-neighbor embeddings, and show its effectiveness on multiple tasks and datasets. Wei et al. wei2019eda provide a great overview of `easy' data augmentation (EDA) techniques for NLP, including synonym replacement as described above, and random deletion, i.e. removing words in the sentence at random with pre-defined probability. They show the effectiveness of EDA across five text classification tasks. However, they mention that EDA may not lead to substantial improvements when using pre-trained models.

        "answer": "Overall, positional matrices encode the positional information of entities in hyper-relational facts, while role embeddings are utilized to model the semantic information of entities. Usually, the role represents the hypernym of entities.",
        "evidence": "As discussed in Sec. 1, designing the proper message function is more conducive to capturing relational patterns of given HKGs and pursuing high empirical performance. Therefore, the first task is to design an expressive search space so that message functions covering various relational patterns can be searched. However, the space of existing GNN searching methods (see Eq. 1 and Fig.) does not apply to HKGs and cannot cover the message functions of GNNs for KGs/HKGs (see Sec. 2.2). Thus, we focus on the search space design of message functions in this paper.\nRecently, various message functions have been proposed for KGs/HKGs as presented in Sec. 2.2. From Fig., we can observe that those message functions are mainly different in these two aspects: 1) the operators (e.g., W , φ, γ) for computing hidden representations, 2) the structure of message functions that decides how computational operators are connected. For the operator selection, existing works manually tune them on different data sets, such as\nMoreover, the structure of message functions for HKGs (StarE and G-MPNN) tends to be deeper and more complex than those for KGs (e.g., CompGCN). This is because the message function needs to process more information (e.g., more entities/roles) when facing the facts with higher arity. These observations motivate us to build space of operators and structures for message function search. Furthermore, we investigate more about the relationship between operators and relational patterns. Generally, the relational pattern can be represented as a certain correlation among r(pemu(e 1 , . . . , e n )) (check more in Appx. B.2), where pemu denotes the permutation. For example, r is symmetry if r(e j , e i ) must be true when r(e i , e j ) is true. Therefore, the message function in the search space must be able to handle such correlation in the form of r(pemu(e 1 , . . . , e n )). In the next, we first introduce the space of operators, and then discuss how they deal with r(pemu(e 1 , . . . , e n )).\n• • Concatenate Operator γ(•): It mainly determines the concatenation way between embedding vectors. In this paper, we set O γ = {concat, mult, wsum}, where wsum is the weighted sum. In general, γ(•) can concatenate embeddings after the positional transform matrix W P (e) , i.e., encoding pemu(e 1 , . . . , e n ).\n• Role Embedding r o : Unlike the positional information of entities encoded by W P (e) , the role embedding is utilized to model the semantic information of entities. For example, the roles in 2nd position of facts playCharacerIn(actor:ZacharyQuinto,character :Spock,movie:StarTrek) and actorAwardIn(actor:ZacharyQuinto,award: BC-BSFC,movie:StarTrek) are different though other entities and roles are same. Thus, the model should be able to capture the role of candidate entities after using W P (e) , e.g., BC-BSFC is unlike to be the 2nd entity of playCharacerIn since its role is award instead of character.\n• Composition Operator φ(•): Following CompGCN, we utilize composition operator φ(•) to capture message between the node and edge embeddings before aggregation step. Note that φ actually encodes the interaction between r and pemu(e 1 , . . . , e n ). While CompGCN and StarE empirically selects the most proper φ(•), we include this operator into the space X . Thus, MSeaHKG is able to automatically search for the most suitable φ(•) in a more efficient way. We combine the settings of CompGCN and StarE to set O φ = {sub, mult, corr, rotat} (rotat (Sun, see others in Sec 2.2). Besides, φ not only occurs between primary relations with entities, but also captures the correlation between roles with entities. • Others: (1) The idt(h) = h operation allows inputs to skip one layer in the message function; (2) Unlike W P (e) , the transform matrix W processes the hidden representations.\nAmong above components, we fix the role embedding and positional transform matrix W P (e) in the message function (see Fig.\nwhere θ k ij ∈ {0, 1} controls the connection between o k i with o k−1 j . Note that {h 0 i } n+1 i=1 = {W P (e1) e 1 , . . . , W P (en) e n , r} if role information is not available in the given HKG. From Fig. (c), we can observe that the structure of message functions is controlled by {θ k ij }. To avoid manual operation selection, we also search for concrete operations of two operators φ and γ. Given the operator set\nThen, φ and γ perform the computation in Eq. 6 could be\nThe message function parameterized by θ mg is defined as: mg r(e 1 , . . . , e n );\nwhere we simplify role embedding r o for simplicity and h K i is outputted by the last layer of Eq. 6. Intuitively, existing GNNs for KGs/HKGs are contained in the MSeaHKG space (compare Fig. and Fig.). Moreover, we include more discussions about the instantiations of other KG/HKGs models in the MSeaHKG space and the capability of handling relational patterns in Appx. B.2.\nIn addition to message function search, we also search for other operators (e.g., agg, comb, act) like existing GNN search methods as shown in Fig. (a) and (b). Let Θ = {θ mg , θ agg , . . . } be parameter set for all operators selection in our MPNN framework. Then, an architecture can be represented as X Θ = {mg(•; θ mg ), agg(•; θ agg ), • • • } (check other functions in Appx. C.1). And existing GNNs for KG/HKG embeddings actually can be represented by different instantiations of Θ. Overall, a GNN model X Θ encodes the given HKG G into embedding space ω = {E, R}, i.e., ω = X Θ (G).\nRole Embedding ro: Unlike the positional information of entities encoded by WP (e) , the role embedding is utilized to model the semantic information of entities (Liu et al., 2021). For example, the roles in 2nd position of facts playCharacerIn(actor:ZacharyQuinto,character :Spock,movie:StarTrek) and actorAwardIn(actor:ZacharyQuinto,award: BC-BSFC,movie:StarTrek) are different though other entities and roles are same. Thus, the model should be able to capture the role of candidate entities after using WP (e) , e.g., BC-BSFC is unlike to be the 2nd entity of playCharacerIn since its role is award instead of character.",

        "evidence": "Among low-resourced scenarios, zero-resourced translation task stands in an extreme level. A zero-resourced translation task is one of the most difficult situation when there is no parallel data between the translating language pair. To the best of our knowledge, there have been yet existed a published work about using NMT for zero-resourced translation tasks up to now. In this section, we extend our strategies using the proposed multilingual NMT approach as first attempts to this extreme situation.\nWe employ language-specific coding and target forcing in a strategy called bridge. Unlike the strategies used in under-resourced translation task, bridge is an entire many-to-many multilingual NMT. Simulating a zero-resourced German INLINEFORM0 French translation task given the available German-English and English-French parallel corpora, after applying language-specific coding and target forcing for each corpus, we mix those data with an English-English data as a “bridge” creating some connection between German and French. We also propose a variant of this strategy that we incorporate French-French data. And we call it universal.\nWe evaluate bridge and universal systems on two German INLINEFORM0 French test sets. They are compared to a direct system, which is an NMT trained on German INLINEFORM1 French data, and to a pivot system, which essentially consists of two separate NMTs trained to translate from German to English and English to French. The direct system should not exist in a real zero-resourced situation. We refer it as the perfect system for comparison purpose only. In case of the pivot system, to generate a translated text in French from a German sentence, we first translate it to English, then the output sentence is fed to the English INLINEFORM2 German NMT system to obtain the French translation. Since there are more than two languages involved in those systems, we increase the number of BPE merging operations proportionally in order to reduce the number of rare words in such systems. We do not expect our proposed systems to perform well with this primitive way of building direct translating connections since this is essentially a difficult task. We report the performance of those systems in Table TABREF23 .\nUnsupprisingly, both bridge and universal systems perform worse than the pivot one. We consider two possible reasons:\nOur target forcing mechanism is moderately primitive. Since the process is applied after language-specific coding, the target forcing symbol is the same for all source sentences in every languages. Thus, the forcing strength might not be enough to guide the decision of the next words. Once the very first word is translated into a word in wrong language, the following words tend to be translated into that wrong language again. Table TABREF24 shows some statistics of the translated words and sentences in wrong language.\nBalancing of the training corpus. Although it is not severe as in the case of mix-source system for large monolingual data, the limited number of sentences in target language can affect the training. The difference of 1.07 BLEU points between bridge and universal might explain this assumption as we added more target data (French) in universal strategy, thus reducing the unbalance in training.\nThose issues would be addressed in our following future work toward the multilingual attention-based NMT.\nWe mix the TED parallel corpus and the substantial monolingual corpus (EPPS+NC+CommonCrawl) and train a mix-source NMT system from those data. The first result is not encouraging when its performance is even worse than the baseline NMT which is trained on the small parallel data only. Not using the same information in the source side, as we discussed in case of mix-multi-source strategy, could explain the degrading in performance of such a system.

        "evidence": "The NLP community is revisiting the role of linguistic structure in applications with the advent of contextual word representations (cwrs) derived from pretraining language models on large corpora BIBREF2, BIBREF3, BIBREF4, BIBREF5. Recent work has shown that downstream task performance may benefit from explicitly injecting a syntactic inductive bias into model architectures BIBREF6, even when cwrs are also used BIBREF7. However, high quality linguistic structure annotation at a large scale remains expensive—a trade-off needs to be made between the quality of the annotations and the computational expense of obtaining them. Shallow syntactic structures (BIBREF8; also called chunk sequences) offer a viable middle ground, by providing a flat, non-hierarchical approximation to phrase-syntactic trees (see Fig. FIGREF1 for an example). These structures can be obtained efficiently, and with high accuracy, using sequence labelers. In this paper we consider shallow syntax to be a proxy for linguistic structure.\nWhile shallow syntactic chunks are almost as ubiquitous as part-of-speech tags in standard NLP pipelines BIBREF9, their relative merits in the presence of cwrs remain unclear. We investigate the role of these structures using two methods. First, we enhance the ELMo architecture BIBREF0 to allow pretraining on predicted shallow syntactic parses, instead of just raw text, so that contextual embeddings make use of shallow syntactic context (§SECREF2). Our second method involves classical addition of chunk features to cwr-infused architectures for four different downstream tasks (§SECREF3). Shallow syntactic information is obtained automatically using a highly accurate model (97% $F_1$ on standard benchmarks). In both settings, we observe only modest gains on three of the four downstream tasks relative to ELMo-only baselines (§SECREF4).\nRecent work has probed the knowledge encoded in cwrs and found they capture a surprisingly large amount of syntax BIBREF10, BIBREF1, BIBREF11. We further examine the contextual embeddings obtained from the enhanced architecture and a shallow syntactic context, using black-box probes from BIBREF1. Our analysis indicates that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo embeddings (§SECREF18).\nOverall, our findings show that while shallow syntax can be somewhat useful, ELMo-style pretraining discovers representations which make additional awareness of shallow syntax largely redundant.\nShallow syntactic information is obtained automatically using a highly accurate model (97% F1 on standard benchmarks).",

It is used to identify and categorise opinions expressed by reviewers on a topic or an entity. Sentiment analysis can be leveraged in marketing, social media analysis, and customer service. Although many studies have been conducted for sentiment analysis in widely spoken languages, this topic is still immature for Turkish and many other languages.\nNeural networks outperform the conventional machine learning algorithms in most classification tasks, including sentiment analysis BIBREF0. In these networks, word embedding vectors are fed as input to overcome the data sparsity problem and make the representations of words more “meaningful” and robust. Those embeddings indicate how close the words are to each other in the vector space model (VSM).\nMost of the studies utilise embeddings, such as word2vec BIBREF1, which take into account the syntactic and semantic representations of the words only. Discarding the sentimental aspects of words may lead to words of different polarities being close to each other in the VSM, if they share similar semantic and syntactic features.\nFor Turkish, there are only a few studies which leverage sentimental information in generating the word and document embeddings. Unlike the studies conducted for English and other widely-spoken languages, in this paper, we use the official dictionaries for this language and combine the unsupervised and supervised scores to generate a unified score for each dimension of the word embeddings in this task.\nOur main contribution is to create original and effective word vectors that capture syntactic, semantic, and sentimental characteristics of words, and use all of this knowledge in generating embeddings. We also utilise the word2vec embeddings trained on a large corpus. Besides using these word embeddings, we also generate hand-crafted features on a review basis and create document vectors. We evaluate those embeddings on two datasets. The results show that we outperform the approaches which do not take into account the sentimental information.

        "evidence": "Following developing news stories is imperative to making real-time decisions on important political and public safety matters. Given the abundance of media providers and languages, this endeavor is an extremely difficult task. As such, there is a strong demand for automatic clustering of news streams, so that they can be organized into stories or themes for further processing. Performing this task in an online and efficient manner is a challenging problem, not only for newswire, but also for scientific articles, online reviews, forum posts, blogs, and microblogs.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream. In this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes. For example, for news articles, we would want to cluster them into related news stories.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. Our clustering approach is part of a larger media monitoring project to solve the problem of monitoring massive text and TV/Radio streams (speech-to-text). In particular, media monitors write intelligence reports about the most relevant events, and being able to search, visualize and explore news clusters assists in gathering more insight about a particular story. Since relevant events may be spawned from any part of the world (and from many multilingual sources), it becomes imperative to cluster news across different languages.\nIn terms of granularity, the type of story clusters we are interested in are the group of articles which, for example : (i) Narrate recent air-strikes in Eastern Ghouta (Syria); (ii) Describe the recent launch of Space X's Falcon Heavy rocket.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream.",

        "question": "Why do the authors limit the test set to nominal antecedents?",
        "answer": "Because these are the only ambiguous cases with respect to translation.",
        "evidence": "We automatically create a test set from the OpenSubtitles corpus BIBREF22 . The goal is to provide a large number of difficult test cases where an English pronoun has to be translated to a German pronoun.\nThe most challenging cases are translating it to either er, sie or es, depending on the grammatical gender of the antecedent. Not only is the translation of it ambiguous, there is also class imbalance in the training data (see Table TABREF18 ). There is roughly a 30% probability that it is aligned to es, which makes it difficult to learn to translate er and sie. We use parsing and automatic co-reference resolution to find translation pairs that satisfy our constraints.\nTo provide a basis for filtering with constraints, we tokenize the whole data set with the Moses tokenizer, generate symmetric word alignments with fast_align BIBREF23 , parse the English text with CoreNLP BIBREF24 , parse the German text with ParZu BIBREF25 and perform coreference resolution on both sides. The coreference chains are obtained with the neural model of CoreNLP for English, and with CorZu for German BIBREF26 , respectively.\nThen we opt for high-precision, aggressive filtering, according to the following protocol: for each pair of sentences INLINEFORM0 in English and German, extract iff\n INLINEFORM0 contains the English pronoun it, and INLINEFORM1 contains a German pronoun that is third person singular (er, sie or es), as indicated by their part-of-speech tags;\nthose pronouns are aligned to each other;\nboth pronouns are in a coreference chain;\ntheir nominal antecedents in the coreference chain are aligned on word level.\nThis removes most candidate pairs, but is necessary to overcome the noise introduced by our preprocessing pipeline, most notably coreference resolution. From the filtered set, we create a balanced test set by randomly sampling 4000 instances of each of the three translations of it under consideration (er, sie, es). We do not balance antecedent distance. See Table TABREF25 for the distribution of pronoun pairs and antecedent distance in the test set.\nFor each sentence pair in the resulting test set, we introduce contrastive translations. A contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one. For an example, see Table TABREF19 , where the pronoun it in the original translation corresponds to sie because the antecedent bat is a feminine noun in German (Fledermaus). We produce wrong translations by replacing sie with one of the other pronouns (er, es).\nNote that, by themselves, these contrastive translations are grammatically correct if the antecedent is outside the current sentence. The test set also contains pronouns with an antecedent in the same sentence (antecedent distance 0). Those examples do not require any additional context for disambiguation and we therefore expect the sentence-level baseline to perform well on them.\nWe take extra care to ensure that the resulting contrastive translations are grammatically correct, because ungrammatical sentences are easily dismissed by an NMT system. For instance, if there are any possessive pronouns (such as seine) in the sentence, we also change their gender to match the personal pronoun replacement.\nThe German coreference resolution system does not resolve es because most instances of es in German are either non-referential forms, or they refer to a clause instead of a nominal antecedent. We limit the test set to nominal antecedents, as these are the only ambiguous cases with respect to translation. For this reason, we have to rely entirely on the English coreference links for the extraction of sentence pairs with it INLINEFORM0 es, as opposed to pairs with it INLINEFORM1 er and it INLINEFORM2 sie where we have coreference chains in both languages.\nOur extraction process respects document boundaries, to ensure we always search for the right context. We extract additional information from the annotated documents, such as the distance (in sentences) between pronouns and their antecedents, the document of origin, lemma, morphology and dependency information if available.\nWe limit the test set to nominal antecedents, as these are the only ambiguous cases with respect to translation.",

        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T)",

        "question": "What do the authors do by using adversarial training in neural networks?",
        "answer": "The authors use adversarial training to reduce the negative influences brought by different crowd annotators.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nThey use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators.",

        "question": "What do the authors employ during training?",
        "answer": "During training the authors employ dropout in the embedding layer.",
        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nDuring training we employ dropout (Srivastava et al., 2014) in the embedding layer.",

        "answer": "Indeed, the salient region is not perfect and the perturbations added to some smooth low frequency area in salient region may be obvious and visible. That’s exactly the reason why we devise our search algorithm to further refine the perturbations in salient region, to make the perturbations as small as possible. From the results and some examples (Figure 5, Table 2), we can find the final perturbations of our attack only occupy a small part in the salient region, and this is in line with the original purpose of the algorithm design. We also test more experiments with 10,000 examples and find our Saliency attack can outperform other attacks stably and the result is statistically significant. We will consider smoothness, high frequency, or heavy texture area in future work.",
        "evidence": "The comparison results are given in Table 2. We can find in all query budgets, our Saliency Attack achieves outstanding performance with a huge gap in terms of SRtrue and three imperceptibility metrics. Although TVDBA, Parsimonious and Square Attack can obtain a better SR, their successful AEs are not true imperceptible, and will be easily detected by some defenses or humans. For Boundary Attack, it can gradually make progress on SR_true, L_2 and MAD as the query budget increases, but they are still much worse than Saliency Attack. This is because it takes at least hundreds of thousands of queries for Boundary Attack to converge (Brendel et al., 2018), which is infeasible in practical. We further test more eamples to verify the statistical significance in Table 5, and present a comparison of SR_true versus query number in Figure 11 in appendix. From the exhabited examples in Figure 5, we can find the AEs of Boundary Attack contain obvious coarse textures because of inadequate query budget. In addition, even restricted in the same salient regions, the perturbations of Parsimonious-seg and Square seg attack are complex and irregular, while our perturbations are smaller and more important, roughtly corresponding to the bright pixels in BP saliency map.

        "question": "What is the underlying assumption of assigning rare concepts a high measure of information content?",
        "answer": "The underlying assumption is that more specific concepts are less frequently used than more common ones.",
        "evidence": "Measures of semantic similarity can be classified into three broad categories : path–based, feature–based and information content (IC). Path–based similarity measures use the structure of a taxonomy to measure similarity – concepts positioned close to each other are more similar than those further apart. Feature–based methods rely on set theoretic measures of overlap between features (union and intersection). The information content measures quantify the amount of information that a concept provides – more specific concepts have a higher amount of information content.\nRadaMBB89 introduce the Conceptual Distance measure. This measure is simply the length of the shortest path between two concepts ( INLINEFORM0 and INLINEFORM1 ) in the MeSH hierarchy. Paths are based on broader than (RB) and narrower than (RN) relations. CaviedesC04 extends this measure to use parent (PAR) and child (CHD) relations. Our INLINEFORM2 measure is simply the reciprocal of this shortest path value (Equation EQREF3 ), so that larger values (approaching 1) indicate a high degree of similarity. DISPLAYFORM0 \nWhile the simplicity of INLINEFORM0 is appealing, it can be misleading when concepts are at different levels of specificity. Two very general concepts may have the same path length as two very specific concepts. WuP94 introduce a correction to INLINEFORM1 that incorporates the depth of the concepts, and the depth of their Least Common Subsumer (LCS). This is the most specific ancestor two concepts share. In this measure, similarity is twice the depth of the two concept's LCS divided by the product of the depths of the individual concepts (Equation EQREF4 ). Note that if there are multiple LCSs for a pair of concepts, the deepest of them is used in this measure. DISPLAYFORM0 \nZhongZLY02 take a very similar approach and again scale the depth of the LCS by the sum of the depths of the two concepts (Equation EQREF5 ), where INLINEFORM0 . The value of INLINEFORM1 was set to 2 based on their recommendations. DISPLAYFORM0 \nPekarS02 offer another variation on INLINEFORM0 , where the shortest path of the two concepts to the LCS is used, in addition to the shortest bath between the LCS and the root of the taxonomy (Equation EQREF6 ). DISPLAYFORM0 \nFeature–based methods represent each concept as a set of features and then measure the overlap or sharing of features to measure similarity. In particular, each concept is represented as the set of their ancestors, and similarity is a ratio of the intersection and union of these features.\nMaedcheS01 quantify the similarity between two concepts as the ratio of the intersection over their union as shown in Equation EQREF8 . DISPLAYFORM0 \nBatetSV11 extend this by excluding any shared features (in the numerator) as shown in Equation EQREF9 . DISPLAYFORM0 \nInformation content is formally defined as the negative log of the probability of a concept. The effect of this is to assign rare (low probability) concepts a high measure of information content, since the underlying assumption is that more specific concepts are less frequently used than more common ones.\nResnik95 modified this notion of information content in order to use it as a similarity measure. He defines the similarity of two concepts to be the information content of their LCS (Equation EQREF11 ). DISPLAYFORM0 \nJiangC97, Lin98, and PirroE10 extend INLINEFORM0 by incorporating the information content of the individual concepts in various different ways. Lin98 defines the similarity between two concepts as the ratio of information content of the LCS with the sum of the individual concept's information content (Equation EQREF12 ). Note that INLINEFORM1 has the same form as INLINEFORM2 and INLINEFORM3 , and is in effect using information content as a measure of specificity (rather than depth). If there is more than one possible LCS, the LCS with the greatest IC is chosen. DISPLAYFORM0 \nJiangC97 define the distance between two concepts to be the sum of the information content of the two concepts minus twice the information content of the concepts' LCS. We modify this from a distance to a similarity measure by taking the reciprocal of the distance (Equation EQREF13 ). Note that the denominator of INLINEFORM0 is very similar to the numerator of INLINEFORM1 . DISPLAYFORM0 \nPirroE10 define the similarity between two concepts as the information content of the two concept's LCS divided by the sum of their individual information content values minus the information content of their LCS (Equation EQREF14 ). Note that INLINEFORM0 can be viewed as a set–theoretic version of INLINEFORM1 .

        "evidence": "We created a new dataset called CW-USPD-2016 (check-worthiness in the US presidential debates 2016) for finding check-worthy claims in context. In particular, we used four transcripts of the 2016 US election: one vice-presidential and three presidential debates. For each debate, we used the publicly-available manual analysis about it from nine reputable fact-checking sources, as shown in Table TABREF7. This could include not just a statement about factuality, but any free text that journalists decided to add, e.g., links to biographies or behavioral analysis of the opponents and moderators. We converted this to binary annotation about whether a particular sentence was annotated for factuality by a given source. Whenever one or more annotations were about part of a sentence, we selected the entire sentence, and when an annotation spanned over multiple sentences, we selected each of them.\nUltimately, we ended up with a dataset of four debates, with a total of 5,415 sentences. The agreement between the sources was low as Table TABREF8 shows: only one sentence was selected by all nine sources, 57 sentences by at least five, 197 by at least three, 388 by at least two, and 880 by at least one. The reason for this is that the different media aimed at annotating sentences according to their own editorial line, rather than trying to be exhaustive in any way. This suggests that the task of predicting which sentence would contain check-worthy claims will be challenging. Thus, below we focus on a ranking task rather than on absolute predictions. Moreover, we predict which sentence would be selected (i) by at least one of the media, or (ii) by a specific medium.\nNote that the investigative journalists did not select the check-worthy claims in isolation. Our analysis shows that these include claims that were highly disputed during the debate, that were relevant to the topic introduced by the moderator, etc. We will make use of these contextual dependencies below, which is something that was not previously tried in related work.\nMoreover, we predict which sentence would be selected (i) by at least one of the media, or (ii) by a specific medium.",

        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nThe combined use of character level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.",

        "answer": "8 different properties.",
        "evidence": "Research in social media analysis is recently seeing a surge in the number of research works applying representation learning models to solve high-level syntactico-semantic tasks such as sentiment analysis [1], semantic textual similarity computation [2], hashtag prediction [3] and so on. Though the performance of the representation learning models are better than the traditional models for all the tasks, little is known about the core properties of a tweet encoded within the representations. In a recent work, Hill et al. [4] perform a comparison of different sentence representation models by evaluating them for different high-level semantic tasks such as paraphrase identification, sentiment classification, question answering, document retrieval and so on. This type of coarse-grained analysis is opaque as it does not clearly reveal the kind of information encoded by the representations. Our work presented here constitutes the first step in opening the black-box of vector embeddings for social media posts, particularly tweets.\nEssentially we ask the following question: “What are the core properties encoded in the given tweet representation?”. We explicitly group the set of these properties into two categories: syntactic and social. Syntactic category includes properties such as tweet length, the order of words in it, the words themselves, slang words, hashtags and named entities in the tweet. On the other hand, social properties consist of `is reply', and `reply time'. We investigate the degree to which the tweet representations encode these properties. We assume that if we cannot train a classifier to predict a property based on its tweet representation, then this property is not encoded in this representation. For example, the model which preserves the tweet length should perform well in predicting the length given the representation generated from the model. Though these elementary property prediction tasks are not directly related to any downstream application, knowing that the model is good at modeling a particular property (e.g., the social properties) indicates that it could excel in correlated applications (e.g., user profiling task). In this work we perform an extensive evaluation of 9 unsupervised and 4 supervised tweet representation models, using 8 different properties. The most relevant work is that of Adi et al. [5], which investigates three sentence properties in comparing unsupervised sentence representation models such as average of words vectors and LSTM auto-encoders. We differ from their work in two ways: (1) While they focus on sentences, we focus on social media posts which opens up the challenge of considering multiple salient properties such as hashtags, named entities, conversations and so on. (2) While they work with only unsupervised representation-learning models, we investigate the traditional unsupervised methods (BOW, LDA), unsupervised representation learning methods (Siamese CBOW, Tweet2Vec), as well as supervised methods (CNN, BLSTM).\nOur main contributions are summarized below.\nThe paper is organized as follows.

If you don’t have access to weights you could replace those exercises with some combination of push ups, pull ups, and chin ups. Next move into three sets of shoulder press and rear delt raises for ten reps each. Finally, do three sets of bicep curls and three sets of tricep dips for ten and thirty reps respectively. The weights and repetitions for each exercise should scale with your comfort and ability doing that exercise. \n\nWhen working out, it’s very important to use good form and not overextend yourself. When lifting heavy weights it’s a good idea to get help from a spotter, and in particular you should never do bench press alone.

        "answer": "We would like to explain our intention behind this decision. Throughout our experiments, we want to show the importance of PCs in LP. Thus, utilizing DeepProbLog in Table 1(b) as the only baseline, we have demonstrated the rich features of PCs as NPPs, since a DNN would require additional techniques to handle missing data. PCs are therefore syntactical sugar of SLASH in this regard.",
        "evidence": "Previous DPPLs, DeepProbLog and NeurASP, introduced the Neural Predicate as an annotated-disjunction or as a propositional atom, respectively, to acquire conditional class probabilities, P (C|X), via the softmax function at the output of an arbitrary DNN. As mentioned in the introduction, this approach has certain limitations concerning inference capabilities. To resolve this issue, we introduce Neural-Probabilisitic Predicates (NPPs).\nFormally, we denote with\na Neural-Probabilistic Predicate h. Thereby, (i) npp is a reserved word to label an NPP, (ii) h a symbolic name of either a PC, NN or a joint of a PC and NN (cf. Fig.), e.g., color_attr is the name of an NPP of Fig.. Additionally, (iii) x denotes a \"term\" and (iv) v 1 , . . . , v n are placeholders for each of the n possible outcomes of h. For example, the placeholders for color_attr are the color attributes of an object (Red, Blue, Green, etc.).\nAn NPP abbreviates an arithmetic literal of the form c = v with c ∈ {h(x)} and v ∈ {v 1 , . . . , v n }. Furthermore, we denote with Π npp a set of NPPs of the form stated in (Eq. 1) and r npp the set of all rules c = v of one NPP, which denotes the possible outcomes, obtained from an NPP in Π npp , e.g. r color_attr = {c = Red, c = Blue, c = Green, ...} for the example depicted in Fig..\nRules of the form npp (h(x), [v 1 , . . . , v n ]) ← Body are used as an abbreviation for application to multiple entities, e.g. multiple slots for the task of set prediction (cf. Fig.). Hereby, Body of the rule is identified by (tautology, true) or ⊥ (contradiction, false) during grounding. Rules of the form Head ← Body with r npp appearing in Head are prohibited for Π npp .\nIn this work, we largely make use of NPPs that contain probabilistic circuits (specifically SPNs) which allow for tractable density estimation and modelling of joint probabilities. In this way, it is possible to answer a much richer set of probabilistic queries, i.e. P (X, C), P (X|C) and P (C|X).\nIn addition to this, we introduce the arguably more interesting type of NPP that combines a neural module with a PC. Hereby, the neural module learns to map the raw input data into an optimal latent representation, e.g. object-based slot representations. The PC, in turn, learns to model the joint distribution of these latent variables and produces the final probability estimates. This type of NPP nicely combines the representational power of neural networks with the advantages of PCs in probability estimation and query flexibility.\nFor making the different probabilistic queries distinguishable in a SLASH program, we introduce the following notation. We denote a given variable with + and the query variable with −. E.g., within the running example of set prediction (cf. Fig.), with the query color_attr(+X, −C) one is asking for P (C|X). Similarly, with color_attr(−X, +C) one is asking for P (X|C) and, finally, with color_attr(−X, −C) for P (X, C).\nTo summarize, an NPP can consist of neural and/or probabilistic modules and produces querydependent probability estimates. Due to the flexibility of its definition, the term NPP contains the predicates of previous works, but also more interesting predicates discussed above. The specific \"flavor\" of an NPP should be chosen depending on what type of probability estimation is required. Lastly, NPPs have the unified loss function of the negative log-likelihood:\n(2) whereby we are assuming the data to be i.i.d., ground truth x i to be the all-ones vector, ξ to be the parameters of the NPP and P (X,C) ξ are the predictions xi obtained from the PC encoded in the NPP.\nIn addition to this, we introduce the arguably more interesting type of NPP that combines a neural module with a PC. Hereby, the neural module learns to map the raw input data into an optimal latent representation, e.g. object-based slot representations. The PC, in turn, learns to model the joint distribution of these latent variables and produces the final probability estimates.

        "question": "Why court designations are collected in their own class court GRT?",
        "answer": "Because court designations play a central role in decisions.",
        "evidence": "We defined 19 fine-grained semantic classes. The (proto)typical classes are person, location and organization. In addition, we defined more specific semantic classes for the legal domain. These are the coarse-grained classes legal norm, case-by-case regulation, court decision and legal literature. The classes legal norm and case-by-case regulation include designations and references, while court decision and legal literature include only references.\nIn the process of developing the typology and annotation guidelines, the fine-grained classes continent KONT (which belongs to location), university UNI, institute IS and museum MUS (which belonged to organization) were eliminated due their low frequency in the corpus (less than 50 occurrences). This is why university, institute and museum were subsumed under the fine-grained class organization. Continent was integrated into landscape.\nThe specification of the 19 fine-grained classes was motivated by the need for distinguishing entities in the legal domain. A first distinction was made between standards and binding acts. Standards, which belong to legal norm, are legal rules adopted by a legislative body in a legislative process. We can distinguish further between law, ordinance (German national standards) and European legal norm. Binding acts (circulars, administrative acts, contracts, administrative regulations, directives, etc.) belong to the category of case-by-case-regulation. It includes regulation (arrangements or instructions on subjects) and contract (agreements between subjects). In addition, court decision and legal literature, which are important in the decision making process, were put into their own categories.\nWithin person, we distinguish between judge and lawyer, key roles mentioned frequently in the decisions. Locations are categorised in terms of their size in country, city and street. Organizations are divided based on their role in the process, into public or social organization, state institution, (private) economic company, mostly as a legal entity, and court as an organ of jurisprudence.\nThe coarse-grained class person PER contains the fine-grained classes judge RR, lawyer AN and person PER (such as accused, plaintiff, defendant, witness, appraiser, expert, etc.), who are involved in a court process and mentioned in a decision. In example (UNKREF19), the same surname occurs twice in a sentence, one as judge and one as person.\nZwar ist Paul Kirchhof RR mit dem Vizepräsidenten Kirchhof PER als dessen Bruder in der Seitenlinie im zweiten Grade verwandt...\n`Although Paul Kirchhof is related to the Vice President Kirchhof as his brother in the second-degree sidelines...'\nThe coarse-grained class location LOC contains names of topographic objects, divided into country LD, city ST, street STR and landscape LDS.

Company UN (UNKREF28) includes commercial legal entities.\nDer FC Bayern München ORG schloss den Beschwerdeführer ... aus dem Verein aus ...\n`Bayern Munich closed the complainant ... from the club ....'\nDie Landesregierung Rheinland-Pfalz INN hat von einer Stellungnahme abgesehen.\n`The state government of Rhineland-Palatinate refrained from commenting.'\n... eingeführte Smartphone-Modellreihe des US-amerikanischen Unternehmens Apple UN ...\n`... introduced smartphone model series of the US company Apple ...'\nCourt designations play a central role in decisions, which is why they are collected in their own class court GRT. These are designations of federal, supreme, provincial and local courts. The designations of the courts at the country level are composed of the names of the ordinary jurisdiction and their location (UNKREF29). Furthermore, brands are often discussed in decisions of the Federal Patent Court. They are subsumed under brand MRK, which can be contextual and semantically ambiguous, such as `Becker' from (UNKREF30), which has evolved from a personal name.\nDiesen Anspruch hat das LSG Mecklenburg-RubineRed!50I Vorpommern GRT mit Urteil vom 22.2.2017 verneint ...\n`This claim was rejected by the LSG Mecklenburg-Vorpommern by judgment of 22.2.2017 ...'\nVorliegend stehen sich die Widerspruchsmarke Becker Mining MRK und die angegriffene Marke Becker MRK gegenüber.\n`In the present case, the opposing brand Becker Mining and the challenged brand Becker face each other.'\nNorms are divided according to their legal status into the fine-grained classes of law GS, ordinance VO and European legal norm EUN. Law is composed of the standards adopted and designated by the legislature (Bundestag, Bundesrat, Landtag). Ordinance includes standards adopted by a federal or provincial government or by a ministry. European legal norm includes norms of European primary or secondary legislation, European organizations and other conventions and agreements.\nExample (UNKREF32) includes a reference to the `Part-Time and Limited Term Employment Act' and the designation 'Basic Law'. The complex reference consists of the reference to the particular section of the law, its name and abbreviation (in brackets), date of issue, the reference in parenthesis and the details of the most recent change. Cases such as this one are a full reference. Example (UNKREF33), on the other hand, shows a short reference consisting of information on the corresponding section of the law and the abbreviated name of the statutory order.\n... § 14 Absatz 2 Satz 2 des Gesetzes über Teil- RedOrange!70I zeitarbeit und IRedOrange!70Ibefristete Arbeitsverträge RedOrange!70I(Tz-RedOrange!70I BfG) vom 21.

It does not have any subclasses, the coarsed and fine-grained versions are identical. In court decision, the name of the official decision-making collection, the volume and the numbered article are cited. Often mentioned are also the court, if necessary the decision type, date and file number. Example (UNKREF39) cites decisions of the Federal Constitutional Court (BVerfG) and the Federal Social Court (BSG). Decisions of the BVerfG are referenced with regard to pages, while decisions of the BSG are sorted according to paragraphs, numbers and marginal numbers.\nLegal literature LIT also contains references, but they refer to legal commentaries, legislative material, legal textbooks and monographs. The commentary in example (UNKREF39) includes the details of an author's and/or publisher's name, the name of a legal norm, a paragraph and a paragraph number.

        "answer": "Apply domain adaptation for SQA.",
        "evidence": "The main focus of this paper is to apply domain adaptation for SQA. In this approach, we have two SQA models (QANets), one trained from target domain data (ASR hypotheses) and another trained from source domain data (reference transcriptions). Because the two domains share common information, some layers in these two models can be tied in order to model the shared features. Hence, we can choose whether each layer in the QA model should be shared. Tying the weights between the source layer and the target layer in order to learn a symmetric mapping is to project both source and target domain data to a shared common space. Different combinations will be investigated in our experiments.\nMore specifically, we incorporate a domain discriminator into the SQA model shown in Figure FIGREF2 , which can enforce the embedding encoder to project the sentences from both source and target domains into a shared common space and consequentially to be ASR-error robust. Although the embedding encoder for both domains may implicitly learn some common latent representations, adversarial learning can provide a more direct training signal for aligning the output distribution of the embedding encoder from both domains. The embedding encoder takes in a sequence of word vectors and generates a sequence of hidden vectors with the same length. We use INLINEFORM0 and INLINEFORM1 ( INLINEFORM2 and INLINEFORM3 ) to represent the hidden vector sequence given the question INLINEFORM4 and the document INLINEFORM5 in the target (source) domain respectively.\nThe domain discriminator INLINEFORM0 focuses on identifying the domain of the vector sequence is from given INLINEFORM1 or INLINEFORM2 , where the objective is to minimize INLINEFORM3 . DISPLAYFORM0 \nGiven a training example from the target domain ( INLINEFORM0 ), INLINEFORM1 learns to assign a lower score to INLINEFORM2 and INLINEFORM3 in that example, that is, to minimize INLINEFORM4 and INLINEFORM5 . On the other hand, given a training example from the source domain ( INLINEFORM6 ), INLINEFORM7 learns to assign a larger value to INLINEFORM8 and INLINEFORM9 .\nFurthermore, we update the parameters of the embedding encoders to maximize the domain classification loss INLINEFORM0 , which works adversarially towards the domain discriminator. We thus expect the model to learn features and structures that can generalize across domains when the outputs of INLINEFORM1 are indistinguishable from the outputs of INLINEFORM2 . The loss function for embedding encoder, INLINEFORM3 , is formulated as DISPLAYFORM0 \nwhere INLINEFORM0 is a hyperparameter. The two embedding encoders in the QA model are learned to maximize INLINEFORM1 while minimizing the loss for QA, INLINEFORM2 . Because the parameters of other layers in QA model are independent to the loss of the domain discriminator, the loss function of other layers, INLINEFORM3 , is equivalent to INLINEFORM4 , that is, INLINEFORM5 .\nAlthough the discriminator is applied to the output of embedding encoder in Figure FIGREF2 , it can be also applied to other layers. Considering that almost all QA model contains such embedding encoders, the proposed approach is expected to generalize to other QA models in addition to QANet.\nThe main focus of this paper is to apply domain adaptation for SQA.",

There is no formal definition of \"extended ASCII\", and even use of the term is sometimes criticized, because it can be mistakenly interpreted to mean that the American National Standards Institute (ANSI) had updated its ANSI X3.4-1986 standard to include more characters, or that the term identifies a single unambiguous encoding, neither of which is the case.\n\nThe ISO standard ISO 8859 was the first international standard to formalize a (limited) expansion of the ASCII character set: of the many language variants it encoded, ISO 8859-1 (\"ISO Latin 1\") – which supports most Western European languages – is best known in the West. There are many other extended ASCII encodings (more than 220 DOS and Windows codepages). EBCDIC (\"the other\" major character code) likewise developed many extended variants (more than 186 EBCDIC codepages) over the decades.\n\nThe technology has largely been rendered technically obsolete by Unicode, which has code points for all the characters encoded in the various attempts to extend ASCII.

        "answer": "Historians, political scientists, and other scholars have long debated the exact nature of fascism. Historian Ian Kershaw once wrote that \"trying to define 'fascism' is like trying to nail jelly to the wall. Each different group described as fascist has at least some unique elements, and many definitions of fascism have been criticized as either too broad or too narrow.\n\nFascism is a far-right, authoritarian, ultranationalist political ideology and movement characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition. Belief in a natural social hierarchy, subordination of individual interests for the perceived good of the nation and race, and strong regimentation of society and the economy. Since the end of World War II in 1945, few parties have openly described themselves as fascist; the term is more often used pejoratively by political opponents. The descriptions of neo-fascist or post-fascist are sometimes employed to describe contemporary parties with ideologies similar to, or rooted in, 20th-century fascist movements. \n\nThe first fascist movements emerged in Italy during World War I, before spreading to other European countries, most notably Germany. Fascism also had adherents outside of Europe. Fascists saw World War I as a revolution that brought massive changes to the nature of war, society, the state, and technology. Fascism rejects assertions that violence is inherently bad and views imperialism, political violence and war as means to national rejuvenation. Fascists often advocate for the establishment of a totalitarian one-party state. Fascism's extreme authoritarianism and nationalism often manifests as belief in racial purity or a master race, usually blended with some variant of racism or bigotry against a demonized \"Other\" that is seen as an existential threat.",

        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities",

        "answer": "Neural machine translation.",
        "evidence": "It is common knowledge in modern NLP that using large amounts of high-quality training data is a key aspect in building successful machine-learning based systems. For this reason, a major challenge when building such systems is obtaining data in the domain of interest. But what defines a domain? Natural language varies greatly across topics, styles, levels of formality, genres and many other linguistic nuances BIBREF0, BIBREF1, BIBREF2. This overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impossible to well-define the exact requirements from such data with respect to all the aforementioned aspects. On top of that, domain labels are usually unavailable – e.g. in large-scale web-crawled data like Common Crawl which was recently used to train state-of-the-art pretrained language models for various tasks BIBREF3.\nDomain data selection is the task of selecting the most appropriate data for a domain from a large corpus given a smaller set of in-domain data BIBREF4, BIBREF5, BIBREF6, BIBREF7. In this work, we propose to use the recent, highly successful self-supervised pre-trained language models, e.g. devlin-etal-2019-bert,liu2019roberta for domain data selection. As pretrained LMs demonstrate state-of-the-art performance across many NLP tasks after being trained on massive amounts of data, we hypothesize that the robust representations they learn can be useful for mapping sentences to domains in an unsupervised, data-driven approach. We show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering. We then propose methods to leverage these emergent domain clusters for domain data selection in two ways:\nVia distance-based retrieval in the sentence embedding space induced by the pretrained language model.\nBy fine-tuning the pretrained language model for binary classification, where positive examples are from the domain of interest.\nOur methods enable to select relevant data for the task while requiring only a small set of monolingual in-domain data. As they are based solely on the representations learned by self-supervised LMs, they do not require additional domain labels which are usually vague and over-simplify the notion of domain in textual data. We evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8. Our data selection methods enable to train NMT models that outperform those trained using the well-established cross-entropy difference method of BIBREF4 across five diverse domains, achieving a recall of more than 95% in all cases with respect to an oracle that selects the “true” in-domain data.\nOur contributions in this work are as follows. First, we show that pre-trained language models are highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner. Second, we propose methods to select in-domain data based on this property using vector-space retrieval and positive-unlabeled fine-tuning of pretrained language models for binary classification. Third, we show the applicability of our proposed data selection methods on a popular benchmark for domain adaptation in machine translation. An additional contribution is a new, improved data split we create for this benchmark, as we point on issues with previous splits used in the literature. The code and data for this work is publicly available. We hope this work will encourage more research on understanding the data landscape in NLP, enabling to “find the right data for the task” in the age of massive models and diverse data sources.\nWe evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8.",

Customers may currently wait from six months to one year for delivery of one of the house's signature bags. Incidentally, should Hermès's leather goods require repair, owners can bring an item to any Hermès store, where it will be shipped to Les Ateliers Hermès in Pantin for repair or reconditioning.[citation needed]\n\nAnother famous Hermès handbag, the \"Birkin bag\", was named after British actress Jane Birkin. In a chance encounter with Jean-Louis Dumas, she complained that her bag was not practical for everyday use. Consequently, he invited her to France where they co-designed the bag in 1984. Birkin has since stopped carrying her namesake bag due to her tendonitis, as the bag became too large and heavy for her to carry. Asked by her that her name be removed and with much back-and-forth comments about various issues such as having her name removed. According to Vogue: \"Jane Birkin 'is satisfied by the measures taken by Hermès', according to the brand, following an investigation by the fashion house [that refuted] claims made by PETA that its famous Birkin bags were being 'constructed from the skins of factory-farmed and cruelly slaughtered crocodiles.' \"\n\nWhile the Kelly and Birkin are two of the house's most famous bags, Hermès has a wide range of other popular handbags. One, the bolide is a dome shaped carry all that comes in varying sizes with a leather shoulder strap. It is widely recognized as the first handbag that was constructed with a zipper.

        "evidence": "Lexical analysis, syntactic analysis, semantic analysis, disclosure analysis and pragmatic analysis are five main steps in natural language processing BIBREF0 , BIBREF1 . While morphology is a basic task in lexical analysis of English, word segmentation is considered a basic task in lexical analysis of Vietnamese and other East Asian languages processing. This task is to determine borders between words in a sentence. In other words, it is segmenting a list of tokens into a list of words such that words are meaningful.\nWord segmentation is the primary step in prior to other natural language processing tasks i. e., term extraction and linguistic analysis (as shown in Figure 1). It identifies the basic meaningful units in input texts which will be processed in the next steps of several applications. For named entity recognization BIBREF2 , word segmentation chunks sentences in input documents into sequences of words before they are further classified in to named entity classes. For Vietnamese language, words and candidate terms can be extracted from Vietnamese copora (such as books, novels, news, and so on) by using a word segmentation tool. Conformed features and context of these words and terms are used to identify named entity tags, topic of documents, or function words. For linguistic analysis, several linguistic features from dictionaries can be used either to annotating POS tags or to identifying the answer sentences. Moreover, language models can be trained by using machine learning approaches and be used in tagging systems, like the named entity recognization system of Tran et al. BIBREF2 .\nMany studies forcus on word segmentation for Asian languages, such as: Chinese, Japanese, Burmese (Myanmar) and Thai BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . Approaches for word segmentation task are variety, from lexicon-based to machine learning-based methods. Recently, machine learning-based methods are used widely to solve this issue, such as: Support Vector Machine or Conditional Random Fields BIBREF7 , BIBREF8 . In general, Chinese is a language which has the most studies on the word segmentation issue. However, there is a lack of survey of word segmentation studies on Asian languages and Vietnamese as well. This paper aims reviewing state-of-the-art word segmentation approaches and systems applying for Vietnamese. This study will be a foundation for studies on Vietnamese word segmentation and other following Vietnamese tasks as well, such as part-of-speech tagger, chunker, or parser systems.\nThere are several studies about the Vietnamese word segmentation task over the last decade. Dinh et al. started this task with Weighted Finite State Transducer (WFST) approach and Neural Network approach BIBREF9 . In addition, machine learning approaches are studied and widely applied to natural language processing and word segmentation as well. In fact, several studies used support vector machines (SVM) and conditional random fields (CRF) for the word segmentation task BIBREF7 , BIBREF8 . Based on annotated corpora and token-based features, studies used machine learning approaches to build word segmentation systems with accuracy about 94%-97%.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation. A all sided review of word segmentation will help next studies on Vietnamese natural language processing tasks have an up-to-date guideline and choose the most suitable solution for the task. The remaining part of the paper is organized as follows. Section II discusses building corpus in Vietnamese, containing linguistic issues and the building progress. Section III briefly mentions methods to model sentences and text in machine learning systems. Next, learning models and approaches for labeling and segmenting sequence data will be presented in Section IV. Section V mainly addresses two existing toolkits, vnTokenizer and JVnSegmenter, for Vietnamese word segmentation. Several experiments based on mentioned approaches and toolkits are described in Section VI. Finally, conclusions and future works are given in Section VII.\nHowever, there is a lack of survey of word segmentation studies on Asian languages and Vietnamese as well.",

All embedding models are learned with Adagrad using 30 iterations. The number of dimensions is chosen for each experiment from INLINEFORM2 based on the tuning data. For the parameters of our model in Equation EQREF7 , we considered values of INLINEFORM3 from {0.1, 0.01, 0.001, 0.0001} and values of INLINEFORM4 from {1, 10, 100, 1000, 10 000, 100 000}. To compute KL divergence, we need to determine a set of classes INLINEFORM5 for each experiment. For classification problems, we can simply consider the given categories, but for the regression problems we need to define such classes by discretizing the numerical values. For the scenicness experiments, we considered scores 3 and 7 as cut-off points, leading to three classes (i.e. less than 3, between 3 and 7, and above 7). Similarly, for each climate related features, we consider two cut-off values for discretization: 5 and 15 for average temperature, 50 and 100 for average precipitation, 10 000 and 17 000 for average solar radiation, 0.7 and 1 for average water vapor pressure, and 3 and 5 for wind speed.

The union did not want the slave stares to secede. After war broke out, it is interesting to note, no foreign government recognized the confederate government. \nBy the mid 1800s, the US had two distinct regions: free states with fast growing economies based on family farming, manufacturing, mining, business and transporting goods. The slave states were based on a plantation system and the only fast growth was in texas. These states were largely rural with few large cities and little industry except in close proximity to free states.",

        "evidence": "Natural text generation, as a key task in NLP, has been advanced substantially thanks to the flourish of neural models BIBREF0 , BIBREF1 . Typical frameworks such as sequence-to-sequence (seq2seq) have been applied to various generation tasks, including machine translation BIBREF2 and dialogue generation BIBREF3 . The standard paradigm to train such neural models is maximum likelihood estimation (MLE), which maximizes the log-likelihood of observing each word in the text given the ground-truth proceeding context BIBREF4 .\nAlthough widely used, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 : during test, the model sequentially predicts the next word conditioned on its previous generated words while during training conditioned on ground-truth words. To tackle this problem, generative adversarial networks (GAN) with reinforcement learning (RL) training approaches have been introduced to text generation tasks BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , where the discriminator is trained to distinguish real and generated text samples to provide reward signals for the generator, and the generator is optimized via policy gradient BIBREF7 .\nHowever, recent studies have shown that potential issues of training GANs on discrete data are more severe than exposure bias BIBREF14 , BIBREF15 . One of the fundamental issues when generating discrete text samples with GANs is training instability. Updating the generator with policy gradient always leads to an unstable training process because it's difficult for the generator to derive positive and stable reward signals from the discriminator even with careful pre-training BIBREF8 . As a result, the generator gets lost due to the high variance of reward signals and the training process may finally collapse BIBREF16 .\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation. At each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples. Then, inspired by reward augmented maximum likelihood (RAML) BIBREF17 , the generator is updated on the samples acquired from a stationary distribution with maximum likelihood estimation (MLE), weighted by the discriminator's rewards. This stationary distribution is designed to guarantee that training samples are surrounding the real data, thus the exploration space of our generator is indeed restricted by the MLE training objective, resulting in more stable training. Compared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient. Our contributions are mainly as follows:\nAt each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples.

        "evidence": "We posses a wealth of prior knowledge about many natural language processing tasks. For example, in text categorization, we know that words such as NBA, player, and basketball are strong indicators of the sports category BIBREF0 , and words like terrible, boring, and messing indicate a negative polarity while words like perfect, exciting, and moving suggest a positive polarity in sentiment classification.\nA key problem arisen here, is how to leverage such knowledge to guide the learning process, an interesting problem for both NLP and machine learning communities. Previous studies addressing the problem fall into several lines. First, to leverage prior knowledge to label data BIBREF1 , BIBREF2 . Second, to encode prior knowledge with a prior on parameters, which can be commonly seen in many Bayesian approaches BIBREF3 , BIBREF4 . Third, to formalise prior knowledge with additional variables and dependencies BIBREF5 . Last, to use prior knowledge to control the distributions over latent output variables BIBREF6 , BIBREF7 , BIBREF8 , which makes the output variables easily interpretable.\nHowever, a crucial problem, which has rarely been addressed, is the bias in the prior knowledge that we supply to the learning model. Would the model be robust or sensitive to the prior knowledge? Or, which kind of knowledge is appropriate for the task? Let's see an example: we may be a baseball fan but unfamiliar with hockey so that we can provide a few number of feature words of baseball, but much less of hockey for a baseball-hockey classification task. Such prior knowledge may mislead the model with heavy bias to baseball. If the model cannot handle this situation appropriately, the performance may be undesirable.\nIn this paper, we investigate into the problem in the framework of Generalized Expectation Criteria BIBREF7 . The study aims to reveal the factors of reducing the sensibility of the prior knowledge and therefore to make the model more robust and practical. To this end, we introduce auxiliary regularization terms in which our prior knowledge is formalized as distribution over output variables. Recall the example just mentioned, though we do not have enough knowledge to provide features for class hockey, it is easy for us to provide some neutral words, namely words that are not strong indicators of any class, like player here. As one of the factors revealed in this paper, supplying neutral feature words can boost the performance remarkably, making the model more robust.\nMore attractively, we do not need manual annotation to label these neutral feature words in our proposed approach.\nMore specifically, we explore three regularization terms to address the problem: (1) a regularization term associated with neutral features; (2) the maximum entropy of class distribution regularization term; and (3) the KL divergence between reference and predicted class distribution. For the first manner, we simply use the most common features as neutral features and assume the neutral features are distributed uniformly over class labels. For the second and third one, we assume we have some knowledge about the class distribution which will be detailed soon later.\nTo summarize, the main contributions of this work are as follows:\nThe rest of the paper is structured as follows: In Section 2, we briefly describe the generalized expectation criteria and present the proposed regularization terms. In Section 3, we conduct extensive experiments to justify the proposed methods. We survey related work in Section 4, and summarize our work in Section 5.\nMore specifically, we explore three regularization terms to address the problem: (1) a regularization term associated with neutral features; (2) the maximum entropy of class distribution regularization term; and (3) the KL divergence between reference and predicted class distribution.",

        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters.

A few days later, John is accosted at a gas station outside of New York City by a group of Russian gangsters, led by Iosef, who fail to intimidate John into selling them his 1969 Boss 429 Mustang. That night, the men break into John's home and kill the puppy before stealing the car. Iosef takes the Mustang to a chop shop to remove its identifying details, but the shop owner, Aurelio, recognizes the vehicle and refuses service. John learns from Aurelio that Iosef is the son of Viggo Tarasov, the boss of the city's Russian mafia.\n\nLearning of his son's actions, Viggo beats and berates Iosef for incurring John's wrath. Viggo reveals that John was formerly a hitman in his employ, renowned and feared in the criminal underworld as the \"Baba Yaga,\" a ruthless and relentless \"man of focus, commitment, and sheer will.\" After John fell in love with Helen, a civilian, Viggo gave him a seemingly \"impossible task\" to earn his freedom.\n\nJohn recovers his concealed stash from his former career, including weapons and gold coins used as underworld currency for special services. He refuses Viggo's attempt to make amends for his son's actions and kills the hit squad subsequently sent to his home. As a result, Viggo puts a $2 million bounty on John's head, and his former mentor Marcus is enlisted to take him out. John lodges in the city at the Continental, a luxurious hotel that serves as neutral ground for the underworld and where conducting criminal \"business\" is strictly forbidden. The hotel's owner and John's old friend, Winston, secretly informs John that Iosef is at the Red Circle nightclub. John infiltrates the club and confronts Iosef, but he is attacked by Kirill, Viggo's henchman, and forced to retreat to the Continental for medical attention.\n\nAs John rests, he is targeted by a hitwoman named Ms. Perkins, who sneaks into his room. Marcus sees Perkins from an adjacent building and fires a warning shot to alert John. He wakes up and subdues Perkins, who reveals that Viggo doubled the bounty for her to kill him in the hotel. She also discloses that Viggo has a high-value stash concealed in a church. John has another hitman, Harry, secure Perkins, but she escapes and kills Harry.\n\nAt the church, John destroys Viggo's cache of cash and extensive blackmail material. When Viggo arrives to assess the damage, John assaults him and his men but is captured after being hit by Kirill's car. John tells Viggo that he will not stop until Iosef is dead because the puppy gave him hope and a chance to not be alone in his grief for Helen. Marcus intervenes again to save John, allowing him to kill Kirill and threaten Viggo into revealing his son's location. John assaults the safehouse and kills Iosef. Afterward, Marcus encourages John to return to the everyday life he has built, but their meeting is witnessed by Perkins, who reveals Marcus's duplicity to Viggo. He has Marcus tortured and killed before calling John to taunt him with the details, drawing him back to the city.\n\nPerkins is executed at Winston's behest for breaking the Continental's rules, and Winston informs John that Viggo is preparing to leave the city by helicopter. John races to the New York Harbor, where he fights and mortally wounds Viggo. Resigned to dying from his own injuries, John watches a video on his phone of Helen telling him they need to go home.

The focus of this paper is on automatic cyberbullying detection in social media text by modelling posts written by bullies, victims, and bystanders of online bullying. We describe the collection and fine-grained annotation of a training corpus for English and Dutch and perform a series of binary classification experiments to determine the feasibility of automatic cyberbullying detection. We make use of linear support vector machines exploiting a rich feature set and investigate which information sources contribute the most for this particular task. Experiments on a holdout test set reveal promising results for the detection of cyberbullying-related posts.

        "question": "Are the authors the first to apply adversarial training for crowd annotation learning?",
        "answer": "Yes, they are.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nTo our best knowledge, we are the first to apply adversarial training for crowd annotation learning.",

This step is fundamental: if the sources cannot support a convincing result, no result will be convincing. In many cases, this involves defining a “core\" set of documents and a “comparison\" set. We often have a specific set of documents in mind: an author's work, a particular journal, a time period. But if we want to say that this “core\" set has some distinctive property, we need a “comparison\" set. Expanding the collection beyond the documents that we would immediately think of has the beneficial effect of increasing our sample size. Having more sources increases the chance that we will notice something consistent across many individually varying contexts.\nComparing sets of documents can sometimes support causal inference, presented as a contrast between a treatment group and a control. In BIBREF0 , the treatment consisted of the text written in the two forums that were eventually closed by Reddit. However, identifying a control group required a considerable amount of time and effort. Reddit is a diverse platform, with a wide variety of interactional and linguistic styles; it would be pointless to compare hate speech forums against forums dedicated to, say, pictures of wrecked bicycles. Chandrasekharan et al. used a matching design, populating the control group with forums that were as similar as possible to the treatment group, but were not banned from Reddit. The goal is to estimate the counterfactual scenario: in this case, what would have happened had the site not taken action against these specific forums? An ideal control would make it possible to distinguish the effect of the treatment — closing the forums — from other idiosyncratic properties of texts that were treated.\nWe also look for categories of documents that might not be useful. We might remove documents that are meta-discourse, like introductions and notes, or documents that are in a language that is not the primary language of the collection, or duplicates when we are working with archived web pages.

        "question": "How do the team process long paragraph-wide contexts?",
        "answer": "To process long paragraph-wide contexts, they take a bottom-up two-level abstraction approach and progressively generate a compositional representation of each word first (low level) and then generate a compositional representation of each discourse unit (high level), with a max-pooling operation in between.",
        "evidence": "Figure 1 illustrates the overall architecture of the discourse-level neural network model that consists of two Bi-LSTM layers, one max-pooling layer in between and one softmax prediction layer. The input of the neural network model is a paragraph containing a sequence of discourse units, while the output is a sequence of discourse relations with one relation between each pair of adjacent discourse units.\nGiven the words sequence of one paragraph as input, the lower Bi-LSTM layer will read the whole paragraph and calculate hidden states as word representations, and a max-pooling layer will be applied to abstract the representation of each discourse unit based on individual word representations. Then another Bi-LSTM layer will run over the sequence of discourse unit representations and compute new representations by further modeling semantic dependencies between discourse units within paragraph. The final softmax prediction layer will concatenate representations of two adjacent discourse units and predict the discourse relation between them.\nWord Vectors as Input: The input of the paragraph-level discourse relation prediction model is a sequence of word vectors, one vector per word in the paragraph. In this work, we used the pre-trained 300-dimension Google English word2vec embeddings. For each word that is not in the vocabulary of Google word2vec, we will randomly initialize a vector with each dimension sampled from the range $[-0.25, 0.25]$ . In addition, recognizing key entities and discourse connective phrases is important for discourse relation recognition, therefore, we concatenate the raw word embeddings with extra linguistic features, specifically one-hot Part-Of-Speech tag embeddings and one-hot named entity tag embeddings.\nBuilding Discourse Unit Representations: We aim to build discourse unit (DU) representations that sufficiently leverage cues for discourse relation prediction from paragraph-wide contexts, including the preceding and following discourse units in a paragraph. To process long paragraph-wide contexts, we take a bottom-up two-level abstraction approach and progressively generate a compositional representation of each word first (low level) and then generate a compositional representation of each discourse unit (high level), with a max-pooling operation in between. At both word-level and DU-level, we choose Bi-LSTM as our basic component for generating compositional representations, mainly considering its capability to capture long-distance dependencies between words (discourse units) and to incorporate influences of context words (discourse units) in each side.\nGiven a variable-length words sequence $X = (x_1,x_2,...,x_L)$ in a paragraph, the word-level Bi-LSTM will process the input sequence by using two separate LSTMs, one process the word sequence from the left to right while the other follows the reversed direction. Therefore, at each word position $t$ , we obtain two hidden states $\\overrightarrow{h_t}, \\overleftarrow{h_t}$ . We concatenate them to get the word representation $h_t = [\\overrightarrow{h_t}, \\overleftarrow{h_t}]$ . Then we apply max-pooling over the sequence of word representations for words in a discourse unit in order to get the discourse unit embedding: \n$$MP_{DU}[j] = \\max _{i=DU\\_start}^{DU\\_end}h_i[j]\\quad \\\\\nwhere, 1 \\le j \\le hidden\\_node\\_size$$   (Eq. 8) \nNext, the DU-level Bi-LSTM will process the sequence of discourse unit embeddings in a paragraph and generate two hidden states $\\overrightarrow{hDU_t}$ and $\\overleftarrow{hDU_t}$ at each discourse unit position. We concatenate them to get the discourse unit representation $hDU_t = [\\overrightarrow{hDU_t}, \\overleftarrow{hDU_t}]$ .\nThe Softmax Prediction Layer: Finally, we concatenate two adjacent discourse unit representations $hDU_{t-1}$ and $hDU_t$ and predict the discourse relation between them using a softmax function:\n$$y_{t-1} = softmax(W_y*[hDU_{t-1},hDU_t]+b_y)$$   (Eq. 9) \nTo process long paragraph-wide contexts, we take a bottom-up two-level abstraction approach and progressively generate a compositional representation of each word first (low level) and then generate a compositional representation of each discourse unit (high level), with a max-pooling operation in between.",

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nAs far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task.",

FL benchmark using DomainNet dataset (refer to experimental details in Section 5) and study how the budget constraint impedes effective training of customizable models. Case 1: FL without budget constraint. First, we individually train networks of different widths by FedAvg. We see that the slimmer networks converge slower and are less generalizable, even though they are trained on all clients (solid lines in Fig.).\nThe results justified the motivation of training wider networks than slimmer ones.\nCase 2: FL with budget constraint. Following the above budget constraint, i.e., R k = (1/2) ⌈4k/K⌉ , we deploy HeteroFL to train budget-compatible prototype models locally. Since HeteroFL was not designed for model customization, data are not fully used: each model prototype is only trained by 1/4 of clients, when clients of the R k = 1 budget can actually afford all slimmer models. Therefore, we extend HeteroFL to a slimmable version (SHeteroFL) by training all affordable prototypes locally. As shown in Fig., wider models (e.g., ×1 net) converge to validation accuracy lower than not only the FedAvg counterparts, but also the slimmer ×0.25 net, showing that the widest model may not be a good candidate model. Therefore, switching models to wider configurations lowers efficiency but does not improve accuracy, which is not a valid customization.\nFrom the perspective of data allocation, it is not surprising that SHeteroFL exhibits a non-monotonous relation between the model width and accuracy.

        "question": "Where are the results showing that promoting diversity of activations decreases the gap between the risk and empirical risk? Also, the bounds are tighter than what?",
        "answer": "This is shown theoretically in Theorem 1 and empirically in Table 2. The main idea of this paper is that by promoting the diversity and penalizing redundancy between the neurons within the same layer, we can improve the generalization. The appearance of the term related to the layer output diversity, i.e.,d_{min} , in the generalization bound in Theorems 1-4 provides theoretical support for the proposed idea. Note that we are not comparing our bound against prior bounds. We just derived a novel upperbound depending on the diversity. For example in Theorem 1, we derived a bound for the generalization gap, i.e.,   L(\\hat{f}) - L(f^*) , which is inversely proportional to d_{min}. This means when d_{min} is higher, the bound gets smaller (tighter) and as the result the gap gets smaller. Such theoretical reasoning has been applied before, see for example [1-4].\n Xie, P., Deng, Y. and Xing, E., 2015.

To study the effect of diversity on the generalization gap, we also report the final training errors and the generalization gap, i.e., training accuracy -test accuracy. As it can be seen, diversity (our approach and DeCov) reduces the test error of the model and yields a better performance. We note that, in accordance with our theoretical findings in Section 2, using diversity indeed reduces overfitting and decreases the empirical generalisation gap of neural networks. In fact, our logdet variant reduces the empirical generalization gap of the model by 1.8% compared to the standard approach. We note that our approach has a small additional time cost. For example for ResNet50, our direct, det and logdet variants take only 0.29%, 0.39%, and 0.49% extra training time, respectively.\nFigure: Sensitivity analysis of λ and γ on both the model accuracy and its generalization ability using ResNet50 trained on ImageNet.\nSensitivity analysis: To further investigate the effect of the proposed diversity strategy, we conduct a sensitivity analysis using ImageNet on the hyperparameters of our methods: γ, which is the RBF parameter used to measure the pairwise similarity between two units, and λ, which controls the contribution of the global diversity term to the global loss. We analyse the effect of the two parameters on both the final performance of the models and its generalization ability. The analysis is presented in Figure and in supplementary material.

It is worth noting that Figure shows that there is a trade-off between the generalization gap and the final error.

Compatibility with Dropout: Dropout) is a popular regularization technique that, similarly to our approach, is applied on top of the layer output and has been known to improve generalization and reduce overfitting. Here, we evaluate the compatibility of our approach with Dropout. We add a Dropout regularizer with 20% rate on top the last intermediate representation layer of both ResNet50 and Wide-ResNet50. The results are reported in Table. We note that adding a diversity regularizer alongside the Dropout consistently yields lower error rates compared to only Dropout except for the det variant on Wide-ResNet50. For Wide-ResNet50, the combination of our logdet variant and Dropout leads to 0.53%, 0.25%, and 0.38% improvement compared to standard approach, Dropout only, and our logdet variant only, respectively.\nBeyond CNN models, we also evaluate the performance of our diversity strategy on modern attention-free, multi-layer perceptron (MLP) based models for image classification. Such models are known to exhibit high overfitting and require regularization. We evaluate how diversity affects the accuracy of such models on CIFAR10. In particular, we conduct a simple experiment using two models: MLP-Mixer, gMLP with four blocks each. The full description of the experimental setup is presented in the Appendix. The results in Table show that employing a diversity strategy can indeed improve the performance of these models thanks to its ability to learn rich and robust representation of the input.\nTransfer learning: Beyond standard classification, the proposed approach can be useful, e.g., in transfer learning, where the main goal is to 'transfer' previously learned representation to solve new tasks. Thus, learning a rich and diverse representation is beneficial and can lead to better transferability. To demonstrate this, we conduct another experiment, where we use ImageNet-pretrained ResNet50 models with the different diversity approaches and we finetune them to CIFAR10 and CIFAR100. The results are reported in Table. As it can be seen, employing a diversity strategy helps in the transfer learning context and leads consistently to lower error rates. For example, the log variant of our approach leads to 0.94% and 1.27% gains on CIFAR10 and CIFAR100, respectively. To further demonstrate the usefulness of promoting diversity, we test the robustness of our approach in the presence of label noise. In such situations, standard neural network tend to overfit to the noisy sample and not generalize well to the test set. Enforcing diversity can lead to better and richer representation attenuating the effect of noise. To show this, we performed additional experiments with label noise (20% and 40%) on CIFAR10 and CIFAR100 using ResNet50. The results are reported in Table. As it can be seen, in the presence of noise, the gap between the standard approach and diversity (Decov and ours) increases.

With an average altitude of 542 m (1,778 ft), much of Hyderabad is situated on hilly terrain around artificial lakes, including the Hussain Sagar lake, predating the city's founding, in the north of the city centre. According to the 2011 Census of India, Hyderabad is the fourth-most populous city in India with a population of 6.9 million residents within the city limits, and has a population of 9.7 million residents in the metropolitan region, making it the sixth-most populous metropolitan area in India. With an output of US$74 billion, Hyderabad has the fifth-largest urban economy in India.\n\nMuhammad Quli Qutb Shah established Hyderabad in 1591 to extend the capital beyond the fortified Golconda. In 1687, the city was annexed by the Mughals. In 1724, Asaf Jah I, the Mughal viceroy, declared his sovereignty and founded the Asaf Jahi dynasty, also known as the Nizams. Hyderabad served as the imperial capital of the Asaf Jahi's from 1769 to 1948. As capital of the princely state of Hyderabad, the city housed the British Residency and cantonment until Indian independence in 1947. Hyderabad was annexed by the Indian Union in 1948 and continued as a capital of Hyderabad State from 1948 to 1956. After the introduction of the States Reorganisation Act of 1956, Hyderabad was made the capital of the newly formed Andhra Pradesh. In 2014, Andhra Pradesh was split to form the state of Telangana, and Hyderabad became the joint capital of the two states with a transitional arrangement scheduled to end in 2024.

        "answer": "Thank you for the helpful suggestion. To alleviate your concern, we state the ‘value-based CTDE method’ in our revised draft.",
        "evidence": "In multi-agent reinforcement learning (MARL), centralized training with decentralized execution (CTDE) is one of the popular learning paradigms since it tackles the non-stationarity issues caused by the changing behaviors of the agents efficiently. Under this paradigm, value-based CTDE has gained impressive attention. It consists of (i) training a joint action-value estimator with an access to global information in a centralized manner and (ii) decomposing the estimator into agent-wise utility functions which can be executed in a decentralized manner. Recently, several value-based CTDE methods have made training efficient and stable by designing the actionvalue estimator as flexible as possible while maintaining the execution constraint on decentralizability.\nHowever, despite the progress on value-based CTDE, agents still often fail to cooperate due to environment randomness, limited observation of agents, and time-varying policies of other agents, especially in highly stochastic environments. For such environments in single-agent settings, risksensitive reinforcement learning (RL) has shown remarkable results by using policies that consider risk rather than simple expectations for return distribution caused by state transitions, rewards, and actions. Here, risk refers to the uncertainty over possible outcomes, and risk-sensitive policies act with a risk measure, such as variance or conditional value at risk (CVaR). The main goal of this paper is to apply this risk-sensitive technique to value-based CTDE to learn more robust policies against various factors of uncertainty.\nTo this end, our motivating observation is that the randomness that must be dealt with in multi-agent settings come from two risk sources: (a) agent-wise risk and (b) environment-wise risk. Here, the agent-wise risk is about how other agents behave cooperatively for a given agent, and the environmentwise risk is about how the environment reacts randomly (i.e., stochasticity of the environmental dynamics) as illustrated in Figure. Unfortunately, existing value-based CTDE methods do not disentangle risk sources explicitly. For instance, recent approaches combining value-based CTDE with distributional RL learn the distribution of each agent-wise utility function but cannot separate different risk sources. This inability to disentangle risks can result to suboptimal policies under risk-sensitive RL; those methods cannot represent agent-wise risk-seeking (cooperative) yet environment-wise risk-averse policies, which are likely to be of the favorable choices in most practical scenarios (i.e., surviving together as a team for a long time under the expectation that every teammate will cooperate for the sake of the team).\nIn this paper, we present Disentangled RIsk-sensitive Multi-Agent reinforcement learning (DRIMA), a novel framework on disentangling risk sources for distributional MARL. The main idea is to separate risk levels in both centralized training and decentralized execution with a hierarchical quantile structure and quantile regression. To be specific, unlike prior works which do not take into consideration different risk sources, DRIMA considers agent-wise risk into each utility function and environment-wise risk into a joint true action-value estimator. Therefore, each utility function is encouraged to learn the action-value distribution with respect to other agents' cooperative policy, and the joint-action value estimator is trained to learn action-value distribution with respect to the environment stochasticity. Thanks to the disentanglement of risk sources, DRIMA is able to obtain desirable policies more efficiently, while as aforementioned, it is difficult to set agent-wise risk-seeking yet environment-wise risk-averse policies in prior state-of-the-art methods.\nWe demonstrate the effectiveness of DRIMA on various scenarios in the StarCraft 1 Multi-Agent Challenge (SMAC) environment which is widely used as the environment for many MARL research . As summarized in Figure, DRIMA significantly outperforms state-of-theart methods, including distributional MARL methods (i.e., DDN and DMIX) and non-distributional ones such as OW-QMIX, CW-QMIX, and QPLEX. Notably, by disentangling risk sources, DRIMA shows impressive results regardless of reward shaping and exploration schedule, whereas existing works learn only a suboptimal policy (see Figure). We hope that our idea will motivate new future research directions such as safe MARL.\nUnder this paradigm,value-based CTDE has gained impressive attention.",

        "evidence": "In this work we find that all six of the ERP components from BIBREF0 can be predicted above chance by a model which has been pretrained using a language modeling objective and then directly trained to predict the components. This is in contrast to prior work which has successfully linked language models to the N400 BIBREF0 and P600 BIBREF7 but not the other ERP components. We also note that contrary to BIBREF7 , we find that an LSTM does contain information that can be used to predict EEG data, and in particular that it can predict the P600. We speculate that the analysis used in BIBREF7 did not find reliable effects because the language models were related to the EEG data through functions chosen a priori (the surprisal, and the `distance' metric). These functions, though interpretable, might be interpretable at the cost of losing much of the information in the representations learned by the network.\nIn addition, we show through our multitask learning analysis that information is shared between ERP components, and between ERP components and behavioral data. Although these relationships must be viewed with caution until they can be verified across multiple datasets and with more variation in neural network architectures, here we consider some potential reasons for our findings. The broad point we wish to make is that by better understanding which ERP components share information with each other and with behavioral data through the type of analysis we present here (multitask learning) or other means, we can better understand what drives each ERP component and in turn the processes involved in human language comprehension.\nThere are at least three possible explanations for why the bidirectional model performs better than the forward-only model. First, it is possible that when a human reads a sentence, he or she predicts the upcoming language input. Under this hypothesis, a model with access to the future language input can do a better job of predicting the current brain activity because the future language is reflected in that brain activity. Second, it is possible that a bidirectional model is simply able to produce better embeddings for each word in the input because it has more context than a forwardonly model. For example, the bidirectional model might be (implicitly) better at anaphora resolution given more context. Under this hypothesis, the additional context given to the model partially compensates for its relative deficit of real-world knowledge compared to a human. Where a human can in many cases solve the anaphora resolution problem by using background knowledge and does not need to see the future language input, a model benefits from additional context. Finally, in our setup, the bidirectional model has more parameters than the forward-only model, and the additional degrees of freedom might give the model an advantage in predicting brain activity.",

Matches between Australia and England were first called \"test matches\" in 1892. The first definitive list of retrospective Tests was written by South Australian journalist Clarence P. Moody two years later and, by the end of the century, had gained acceptance.\n\nThere are now twelve full ICC member countries playing Test cricket.

        "answer": "Although its popularity is arguably greater in Latin America and Asia now, baseball is still commonly referred to as \"America's Pastime.\" This is partly because game was invented in the United States 180 years ago and was the dominate sport for much of the time since. But baseball is also a game obsessed with its own history, much like America is with hers and we can trace a lot of the story of baseball alongside the story of America. \n\nWhile the country was fighting itself to determine the shape of its future during the Civil War, the game of baseball was taking shape and spreading to the south by northern war prisoners. After the war, when mass market commercialism became available, baseball and its products were the primary sport marketed to people across the country. Many of the first American celebrities were in fact baseball players, their faces and names seen by millions of people through the rising circulation of newspapers and distribution of baseball cards.\n\nEven later, baseball was at the forefront of the Civil Rights Movement. Jackie Robinson became the first Black player to play Major League Baseball in the modern era. The integration of baseball was an early and important step in the broader Civil Rights Movement. Since then, baseball has been one of the most diverse sports in the world, its demographics closely representing that of the whole country.\n\nIn many ways, baseball culture has become synonymous with American culture in general. The season takes place through summer. There are hot dogs, nachos, a lot of sitting around, fireworks, and games on 4th of July.\n\nSo even as more countries and cultures find a way to make baseball their own, the sport can always claim its place as America's Pastime.",

        "question": "Colonies or provinces? How did the Spanish Empire treat its overseas territories?",
        "evidence": "",
        "answer": "The Spanish Empire lasted for four centuries, from the arrival of Columbus in America in 1492 until the loss of its last overseas territories (Cuba, Puerto Rico and the Philippines) in 1898. In its last period, towards the middle of the 19th century, a debate arose that, to this day, still raises blisters regarding the definition of these lands. A part of the population continues to consider that the lands that Spain conquered beyond the seas were colonies, while another part defines them as provinces. That is, like Valladolid, Barcelona or Guadalajara.\nIn the Royal Decree of Carlos V, promulgated in 1519, which was later included in the Compilation of Laws of the Indies, the following declaration of intent could already be read: «That the West Indies be always united to the Crown of Castile and that cannot be alienated. We order that, at no time, they can be separated by our royal crown of Castile, disunited or divided in whole or in part or in favor of any person.»\nThe Spanish laws always spoke of \"provinces\", \"kingdoms\", \"republics\", \"empires\" or \"territories of islands and mainland\". In other words, the term \"colony\" was never used in the legal field for the territories that had been incorporated into the Crown of Castile. It was incorporated later and only with a critical and propagandistic desire, the same as it is today when it is used. This is not an excuse to deny that in the Spanish overseas territories there were models of exploitation that could be considered colonial, such as the monopoly of the extraction of precious metals or certain types of commercial companies. One of the main proofs is that the overseas territories reproduced most of the institutions of the metropolis.\nBernardino Bravo Lira, winner of Chile's 2010 National History Award, noted an important difference:\n\"Politically, the Indies were incorporated into the Crown and not into the Kingdom of Castile. This means that they were not considered as simple land, without their own political personality and, therefore, susceptible to submission to a foreign power. They were considered as other kingdoms, similar to Castile and other Europeans, endowed with the same attributes as them. For this reason they were classified and organized under the form of State of the Indies and not colonies. The kingdoms of the Indies had all the elements that then made up a State: territory, population, nationality, institutions, government and their own legislation.\"\nThis means that, contrary to what most critical authors think, the territories conquered by Spain were never considered as colonies devoid of rights. Moreover, its inhabitants were considered, already with Queen Isabella of Castilla, vassals of the Crown like any other inhabitant of the Iberian Peninsula, once the conquest process was completed in the 16th century. That is why the Indies, which have been known as \"America\" ​​since the 17th century, owed allegiance only to the King, who governed through the institutions created for that purpose and which were governed by officials designated for that purpose.",

        "evidence": "In the Indian subcontinent\n\nHyderabadi vegetable biryani served in Tampa, U.S.\n\nBiryani of Lahore\nThere are many types of biryani, whose names are often based on their region of origin. For example, Sindhi biryani developed in the Sindh region of what is now Pakistan, and Hyderabadi biryani developed in the city of Hyderabad in South India.\n\nSome have taken the name of the shop that sells it, for example: Haji Biriyani, Haji Nanna Biriyani in Old Dhaka, Fakhruddin Biriyani in Dhaka, Students biryani in Karachi, Lucky biryani in Bandra, Mumbai and Baghdadi biryani in Colaba, Mumbai. Biryanis are often specific to the Muslim communities where they originate; they are usually the defining dishes of those communities.\n\nAmbur/Vaniyambadi biryani\nAmbur/Vaniyambadi biryani is a variety cooked in the neighboring towns of Ambur and Vaniyambadi in the Tirupattur district of the northeastern part of Tamil Nadu, which has a high Muslim population. It was introduced by the Nawabs of Arcot who once ruled the area. It is typically made with jeera samba rice.\n\nThe Ambur/Vaniyambadi biryani is accompanied by dhalcha, a sour brinjal curry, and pachadi or raitha (sliced onions mixed with plain yogurt, tomato, chilies, and salt). It has a distinctive aroma and is considered light on the stomach. The usage of spice is moderate and curd is used as a gravy base. It also has a higher ratio of meat to rice. Ambur-style biriyani is popular as street food all across South India.\n\nBeef/Kalyani biryani\n\nBeef biryani\nBeef biryani, as the name implies, uses beef as the meat. In Hyderabad, it is famous as Kalyani biryani, in which buffalo or cow meat is used. This meal was started after the Kalyani Nawabs of Bidar came to Hyderabad sometime in the 18th century. The Kalyani biryani is made with small cubes of beef, regular spices, onions, and many tomatoes. It has a distinct tomato, jeera and dhania flavour. In Kerala, beef biryani is well known. The Bhatkali biryani is a special variant where the main ingredient is onion. Its variations include beef, goat, chicken, titar, egg, fish, crab, prawn, and vegetable biryani.\n\nBhatkali/Navayathi biryani\nThis is an integral part of the Navayath cuisine and a specialty of Bhatkal, a coastal town in Karnataka. Its origins are traced to the Persian traders who left behind not only biryani but a variation of kababs and Indian breads. In Bhatkali biryani, the meat is cooked in an onion and green chili-based masala and layered with fragrant rice. It has a unique spicy and heady flavour, and the rice is overwhelmingly white with mild streaks of orange.\n\nThough similar to those in Thalassery, this biryani differs with lingering after-notes of mashed onions laced with garlic. A few chilies and spices littered with curry leaves lends a unique flavour to Bhatkal biryani. No oil is used.\n\nBohri biryani\nBohri biryani, prepared by the Bohris is flavoured with lots of tomatoes. It is popular in Karachi.\n\nChettinad biryani\nChettinad biryani is famous in the Indian state of Tamil Nadu. It is made of jeeraka samba rice, and smells of spices and ghee. It is best taken with nenju elumbu kuzhambu, a spicy and tangy goat meat gravy[citation needed]. The podi kozhi is usually topped with fried onions and curry leaves.\n\nDegh Biryani\nDegh Biryani especially served in Parbhani District and surroundings\nDegh Ki biryani/Akhni Biryani of Parbhani\nDegh ki biryani is a typical biryani made from small cubes of beef or mutton. This biryani is famous in Parbhani and generally served at weddings.\n\nThe meat is flavoured with ginger, garlic, red chili, cumin, garam masala, fried onion and curd. This biryani is also known as kachay gosht ki biryani or dum biryani, where the meat is marinated and cooked along with short grain and fine rice. It is left on a slow fire or dum for a fragrant and aromatic flavour.\n\nDelhi biryani\nThe Delhi version of biryani developed a unique local flavour as the Mughal kings shifted their political capital to the North Indian city of Delhi. Until the 1950s, most people cooked biryani in their home and rarely ate at eateries outside of their homes. Hence, restaurants primarily catered to travellers and merchants. Any region that saw more of these two classes of people nurtured more restaurants, and thus their own versions of biryani. This is the reason why most shops that sold biryani in Delhi, tended to be near mosques such as Jama Masjid (for travellers) or traditional shopping districts (such as Chandni Chowk).\n\nEach part of Delhi has its own style of biryani, often based on its original purpose, thus giving rise to Nizamuddin biryani, Shahjahanabad biryani, etc. Nizamuddin biryani usually had little expensive meat and spices as it was primarily meant to be made in bulk for offering at the Nizamuddin Dargah shrine and thereafter to be distributed to devotees. A non-dum biryani, using many green chillies, popularized by the Babu Shahi Bawarchi shops located outside the National Sports Club in Delhi is informally called Babu Shahi biryani. Another version of Delhi biryani uses achaar (pickles) and is called achaari biryani.\n\nDhakaiya biryani\n\nDhakaiya biriyani\nThe city of Dhaka in Bangladesh is known for selling Chevon Biryani, a dish made with highly seasoned rice and goat meat. The recipe includes: highly seasoned rice, goat meat, mustard oil, garlic, onion, black pepper, saffron, clove, cardamom, cinnamon, salt, lemon, doi, peanuts, cream, raisins and a small amount of cheese (either from cows or buffalo). Haji biryani is a favourite among Bangladeshis living abroad. A recipe was handed down by the founder of one Dhaka restaurant to the next generation. Haji Mohammad Shahed claimed, \"I have never changed anything, not even the amount of salt\".\n\nDhakaiya Kacchi Biryani is accompanied by borhani, a salted mint drink made of yogurt, coriander, mint and salt.\n\nDindigul biryani\nThe Dindigul town of Tamil Nadu is noted for its biryani, which uses a little curd and lemon juice for a tangy taste.\n\nDonne biryani\nMilitary hotels of Bangalore in Karnataka are known for selling Biryani served in dried plantain pouches called Donne available in .It is made typically made from jeera samba rice, yogurt with lot of common mint and coriander leaves, \n\nHyderabadi biryani\nMain article: Hyderabadi biryani\n\nHyderabadi Chicken Biryani\nHyderabadi biryani is India’s most famous biryani; some say biryani is synonymous with Hyderabad. The crown dish of Hyderabadi Cuisine, Hyderabadi biryani developed under the rule of Asaf Jah I, who was first appointed as the governor of Deccan by the Mughal Emperor Aurangzeb. It is made with basmati rice, spices and goat meat. Popular variations use chicken instead of goat meat. There are various forms of Hyderabadi biryani, such as kachay gosht ki biryani or dum biryani, where goat meat is marinated and cooked along with the rice. It is left on a slow fire or dum for a fragrant and aromatic flavour.\n\nMemoni/Kutchi biryani\nMemoni biryani is an extremely spicy variety developed by the Memons of Gujarat-Sindh region in India and Pakistan. It is made with mutton, dahi, fried onions, and potatoes, and fewer tomatoes compared to Sindhi biryani.\n\nKalyani biryani\nKalyani biryani is a typical biryani from the former state of Hyderabad Deccan. Also known as the \"poor man's\" Hyderabadi biryani, Kalyani biryani is always made from small cubes of buffalo meat.\n\nThe meat is flavoured with ginger, garlic, turmeric, red chili, cumin, coriander powder, and much onion and tomato. It is first cooked as a thick curry and then cooked along with rice. Then given dum (the Indian method of steaming in a covered pot).\n\nKalyani biryani is supposed to have originated in Bidar during the reign of the Kalyani Nawabs, who migrated to Hyderabad after one of the Nawabs, Ghazanfur Jang married into the Asaf Jahi family uniting their realms. Kalyani biryani was served by the Kalyani Nawabs to all of their subjects who came from Bidar to Hyderabad and stayed or visited their devdi or noble mansion.\n\nKolkata biryani\n\nKolkata biryani\nCalcutta or Kolkata biryani evolved from the Lucknow style, when Awadh's last Nawab Wajid Ali Shah was exiled in 1856 to the Kolkata suburb of Metiabruz. Shah brought his personal chef with him. The Kolkata biriyani is characterized by the unique presence of potato in it, along with meat and egg ('dim' in Bengali). It is said that the Nawab, having is lost his kingdom, could not afford meat, so his chefs tried to compensate by adding potatoes. But serious historians have rejected this as a myth. When Wajid Ali Shah arrived in Kolkata, the potato was an exotic vegetable in India and the former Nawab of Awadh, being a connoisseur of great food encouraged their chefs to try new ingredients in the dish. The Kolkata biryani is much lighter on spices but high on flavours.\n\nRawther biryani\nThis type of biryani is popular in the Palakkad and Coimbatore regions. This was most commonly prepared by Rawther families in Kerala and Tamil Nadu. This type of biryani is cooked in a different style. Goat meat is most commonly used and it is entirely different from Malabar biryani.[citation needed]\n\nSindhi biryani\n\nSindhi biryani\nThe exotic and aromatic Sindhi biryani is known in Pakistan for its spicy taste, fragrant rice, and delicate meat. Sindhi biryani is a beloved staple in food menus of Pakistani and Sindhi cuisine. Sindhi biryani is prepared with meat and a mixture of basmati rice, vegetables, and various spices.\n\nSri Lankan biryani\n\nSri Lankan chicken biryani\nBiryani was brought into Sri Lanka by the South Indian Muslims who were trading in the Northern part of Sri Lanka and in Colombo in the early 1900s.[citation needed] In Sri Lanka, it is Buryani, a colloquial word which generated from Buhari Biryani. In many cases, Sri Lankan biryani is much spicier than most Indian varieties. Side dishes may include acchar, Malay pickle, cashew curry and mint sambol.[citation needed]\n\nThalassery biryani\nMain article: Thalassery cuisine\n\nThalassery biryani\nThalassery biryani is the variation of biryani found in the Indian state of Kerala. It is one of the many dishes of the Malabar Muslim community, and very popular.\n\nThe ingredients are chicken, spices and the specialty is the choice of rice called khyma. Khyma rice is generally mixed with ghee. Although a large number of spices such as mace, cashew nuts, sultana raisins, fennel-cumin seeds, tomato, onion, ginger, garlic, shallot, cloves and cinnamon are used, there is only a small amount of chili (or chili powder) used in its preparation.\n\nA pakki biryani, the Thalassery biryani uses a small-grained thin (not round) fragrant variety of rice known as khyma or jeerakasala. The dum method of preparation (sealing the lid with dough  or cloth and placing red-hot charcoal above the lid) is applied here to avoid scorched rice.",

        "evidence": "With the availability of rich data on users' locations, profiles and search history, personalization has become the leading trend in large-scale information retrieval. However, efficiency through personalization is not yet the most suitable model when tackling domain-specific searches. This is due to several factors, such as the lexical and semantic challenges of domain-specific data that often include advanced argumentation and complex contextual information, the higher sparseness of relevant information sources, and the more pronounced lack of similarities between users' searches.\nA recent study on expert search strategies among healthcare information professionals BIBREF0 showed that, for a given search task, they spend an average of 60 minutes per collection or database, 3 minutes to examine the relevance of each document, and 4 hours of total search time. When written in steps, their search strategy spans over 15 lines and can reach up to 105 lines.\nWith the abundance of information sources in the medical domain, consumers are more and more faced with a similar challenge, one that needs dedicated solutions that can adapt to the heterogeneity and specifics of health-related information.\nDedicated Question Answering (QA) systems are one of the viable solutions to this problem as they are designed to understand natural language questions without relying on external information on the users.\nIn the context of QA, the goal of Recognizing Question Entailment (RQE) is to retrieve answers to a premise question ( INLINEFORM0 ) by retrieving inferred or entailed questions, called hypothesis questions ( INLINEFORM1 ) that already have associated answers. Therefore, we define the entailment relation between two questions as: a question INLINEFORM2 entails a question INLINEFORM3 if every answer to INLINEFORM4 is also a correct answer to INLINEFORM5 BIBREF1 .\nRQE is particularly relevant due to the increasing numbers of similar questions posted online BIBREF2 and its ability to solve differently the challenging issues of question understanding and answer extraction.

It was founded in 1998 as a retailer of yoga pants and other yoga wear, and has expanded to also sell athletic wear, lifestyle apparel, accessories, and personal care products. The company has 574 stores internationally, and also sells online.\n\nHistory\nLululemon was founded in 1998 by Chip Wilson in Vancouver, with its first standalone store opening in November 2000. Wilson created the name to have many L's so that it would sound western to Japanese buyers, who often have difficulty pronouncing the letter. He later remarked that he found it \"funny to watch [Japanese speakers] try and say it\" and that \"it was the only reason behind the name\".\n\nThe company's initial public offering was in July 2007, raising $327.6 million by selling 18.2 million shares. Christine Day, a former co-president of Starbucks, became chief executive officer in 2008.\n\nIn 2013, the company made its third consecutive appearance on Fortune's Fastest-Growing Companies list. In December 2013, founder Chip Wilson announced his resignation as chairman, and that the president of TOMS Shoes, Laurent Potdevin, would become CEO.\n\nIn 2014, Lululemon opened its first store in Europe, a flagship shop in Covent Garden, London. In February 2015, Wilson announced that he was resigning from the board, and that Michael Casey, former lead director of the board, would replace him. In 2018, Laurent Potdevin resigned as CEO and from the company's board due to misconduct.\n\nFrom its founding through 2015, Lululemon incorporated elements of Landmark Forum into its leadership and development training. According to a company source, seventy per cent of managers are hired internally. Store managers are responsible for their store's layout, color coordination, and community involvement.\n\nIn 2019, Lululemon announced an investment in MIRROR, a fitness startup that sells an interactive mirror with a camera and speakers for at-home workouts. The companies planned to create new content for the device, starting with meditation classes. In June 2020, Lululemon announced a $500 million deal to purchase MIRROR, capitalizing on a growing trend of people conducting virtual workouts at home instead of going to a gym due to the COVID-19 pandemic. The company eventually took a post-tax impairment charge of $442.7 million related to the acquisition at the end of fiscal 2022.\n\nProducts\nLululemon sells athletic wear including tops, yoga pants – a product that the company invented, shorts, sweaters, jackets and undergarments, as well as hair accessories, bags, yoga mats, water bottles, and personal care products such as deodorant and dry shampoo. Lululemon trademarked its original fabric, Luon, which included a higher-than-average amount of nylon microfiber, in 2005. Since then, the company has produced several different types of fabrics, including compression and moisture-wicking designs. Lululemon is primarily known for their leggings, which first made the brand popular.\n\nLululemon maintains a research and development lab, \"Whitespace,\" within its headquarters. It has around 50 employees including scientists and physiologists.\n\nIn 2019, the company launched a luxury streetwear brand called Lab in a few of its stores. In the same year, the company announced plans to double its men's business in the next five years beyond its women's and accessory business, competing against other athletic wear such as Nike and Under Armour.\n\nMarketing\nTwo Lululemon stores with their products in exhibition, (left) Promenade; (right): Hong Kong\nOriginally known for women's yoga apparel, by 2019 Lululemon had grown by acquiring more male customers and adapting its product and marketing strategies accordingly; it plans to increase awareness of its brand among men. The company has been stated to use \"holistic guerrilla marketing\", aiming to make customers feel that by wearing Lululemon clothing they are part of a larger community. It uses social media including Facebook, Twitter and Instagram as a main method of marketing the company and its products. Lululemon offers fitness instructors 25 percent off their orders.\n\nControversies\nIn November 2007, The New York Times reported that Lululemon made false claims about its Vitasea clothing product; the firm had claimed that the clothing, made from seaweed, provided \"anti-inflammatory, antibacterial, hydrating and detoxifying benefits\" but laboratory tests failed to find significant differences in mineral levels between ordinary T-shirt cotton and Vitasea fabric. Lululemon was subsequently forced to remove all health claims from its seaweed-based products marketed in Canada, following a demand from a Canadian oversight agency, the Competition Bureau of Canada.\n\nIn 2013, some customers complained that the clothing was of poor quality, with some items being \"too sheer\", having holes appear, and falling apart after a few uses. In December 2010, Lululemon recalled some of the store's reusable bags that were made from polypropylene, based on reports of high levels of lead. In 2013, Lululemon recalled its black yoga pants that were unintentionally transparent and \"too thin\"; the recall, which amounted to approximately 17 percent of all women's pants sold in its stores, impacted its financial results. The resulting financial loss and damage to the brand led to the forced departure of the company's Chief product officer, Sheree Waterson, and of its CEO, Christine Day.\n\nFounder Chip Wilson has made numerous controversial statements. In a 2004 interview, Wilson mocked Japanese pronunciation of the company's name. In 2013 he said that the company did not make clothes for plus-size women because it was too costly. In an effort to explain away excessive pilling in the brand's clothing, he blamed some customers for wearing Lululemon's clothes improperly or for having body shapes inconsistent with his clothes. In an interview for Bloomberg TV in 2013, he stated that some women's bodies were unsuitable for the brand's clothing. Time called the remarks \"fat shaming\". Comments such as these reportedly led to Wilson's resignation as chairman. In June 2016, Wilson published an open letter to shareholders stating that the company had \"lost its way\" and given up market share to Nike and Under Armour, after he was denied the opportunity to speak at the company's annual meetings. Since then, Wilson has used his website \"Elevate Lululemon\" to criticize the brand and business.\n\nIn 2012, Lululemon filed a lawsuit against Calvin Klein and supplier G-III Apparel Group for infringement of three of its design patents for yoga pants. The lawsuit was somewhat unusual as it involved a designer seeking to assert intellectual property protection in clothing through patent rights. The case was settled out of court the same year.\n\nIn 2021, a Business Insider report revealed that an unnamed company director pushed employees to create an All Lives Matter campaign to be displayed on its website in response to the murder of George Floyd. Employees pushed back but were told to move forward and create a mock up with the All Lives Matter copy, however they also created a Black Lives Matter artwork mock up that in the end was selected instead. The director apologized to 200 members of the company over conference call and subsequently left the company.\n\nIn September 2022, 1,698 yoga teachers and students via advocacy groups Stand.earth and Actions Speaks Louder wrote to the company demanding a transition to 100% renewable energy by 2030. They claimed that roughly half of the firm's energy came from coal production.",

The simplest mathematical realization of spatial network is a lattice or a random geometric graph (see figure in the right), where nodes are distributed uniformly at random over a two-dimensional plane; a pair of nodes are connected if the Euclidean distance is smaller than a given neighborhood radius. Transportation and mobility networks, Internet, mobile phone networks, power grids, social and contact networks and biological neural networks are all examples where the underlying space is relevant and where the graph's topology alone does not contain all the information.

He passed away from cardiac arrest caused by a propofol and benzodiazepine overdose on June 25, 2009. He donated (at least) a remarkable 500,000,000 dollars to charity. Michael is also known as The King of Pop (a title given to him by Elizabeth Taylor) or under the initials MJ. Dubbed the King of Pop, he is regarded as one of the most significant cultural figures of the 20th century.\n\nHe is the creator of the best-selling album of all time, Thriller (1982), awarded 30 times platinum at the beginning of 2016. His other albums Bad, Dangerous and History are all among the best charting albums of all time and all reached the number one position in the US charts.\n\nJackson was the first black artist whose music video (Billie Jean) was aired on MTV, and with that success, he broke down a racial barrier in the music industry. With his music and music videos, he revolutionized the world of pop music. Jackson is very well known for his signature dance moves (moonwalk, lean, sidewalk, Thriller dance), his famous clothing (black hat, white sequined glove, military jackets), his unique singing voice, and songs like Off the Wall, Don't Stop 'till You Get Enough, Thriller, Billie Jean, Beat It, Bad, The Way You Make Me Feel, Man In the Mirror, Heal the World. Black or White, Remember the Time, Earth Song and They Don't Care About Us. He also is the best entertainer of all time according to the Guinness Book of Records, and one of the best-selling solo artists of all time.\n\nHe had 13 Billboard Hot 100 number-one singles (more than any other male artist in the Hot 100 era) and was the first artist to have a top-ten single in the Billboard Hot 100 in five different decades. His honors include 15 Grammy Awards, 6 Brit Awards, a Golden Globe Award and 39 Guinness World Records, including the \"Most Successful Entertainer of All Time\". Jackson's inductions include the Rock and Roll Hall of Fame (twice), the Vocal Group Hall of Fame, the Songwriters Hall of Fame, the Dance Hall of Fame (the only recording artist to be inducted) and the Rhythm and Blues Music Hall of Fame.

        "question": "Is the authors' work the first consideration of exploring the capsule network to knowledge graph completion and search personalization?",
        "answer": "Yes, it is.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nWe propose an embedding model CapsE using the capsule network (Sabour et al., 2017) for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.",

        "evidence": "We use sentiment analysis and paraphrase detection as downstream tasks, as for these two tasks, 1-2 character edits do not change the output labels.\nFor sentiment classification, we systematically study the effect of character-level adversarial attacks on two architectures and four different input formats. The first architecture encodes the input sentence into a sequence of embeddings, which are then sequentially processed by a BiLSTM. The first and last states of the BiLSTM are then used by the softmax layer to predict the sentiment of the input. We consider three input formats for this architecture: (1) Word-only: where the input words are encoded using a lookup table; (2) Char-only: where the input words are encoded using a separate single-layered BiLSTM over their characters; and (3) Word $+$ Char: where the input words are encoded using a concatenation of (1) and (2) .\nThe second architecture uses the fine-tuned BERT model BIBREF26 , with an input format of word-piece tokenization. This model has recently set a new state-of-the-art on several NLP benchmarks, including the sentiment analysis task we consider here. All models are trained and evaluated on the binary version of the sentence-level Stanford Sentiment Treebank BIBREF24 dataset with only positive and negative reviews.\nWe also consider the task of paraphrase detection. Here too, we make use of the fine-tuned BERT BIBREF26 , which is trained and evaluated on the Microsoft Research Paraphrase Corpus (MRPC) BIBREF27 .\nTwo common methods for dealing with adversarial examples include: (1) data augmentation (DA) BIBREF28 ; and (2) adversarial training (Adv) BIBREF29 . In DA, the trained model is fine-tuned after augmenting the training set with an equal number of examples randomly attacked with a 1-character edit. In Adv, the trained model is fine-tuned with additional adversarial examples (selected at random) that produce incorrect predictions from the current-state classifier. The process is repeated iteratively, generating and adding newer adversarial examples from the updated classifier model, until the adversarial accuracy on dev set stops improving.\nIn Table 3 , we examine the robustness of the sentiment models under each attack and defense method. In the absence of any attack or defense, BERT (a word-piece model) performs the best ( $90.3\\%$ ) followed by word+char models ( $80.5\\%$ ), word-only models ( $79.2\\%$ ) and then char-only models ( $70.3\\%$ ). However, even single-character attacks (chosen adversarially) can be catastrophic, resulting in a significantly degraded performance of $46\\%$ , $57\\%$ , $59\\%$ and $33\\%$ , respectively under the `all' setting.\nIntuitively, one might suppose that word-piece and character-level models would be more robust to such attacks given they can make use of the remaining context. However, we find that they are the more susceptible. To see why, note that the word `beautiful' can only be altered in a few ways for word-only models, either leading to an UNK or an existing vocabulary word, whereas, word-piece and character-only models treat each unique character combination differently. This provides more variations that an attacker can exploit. Following similar reasoning, add and key attacks pose a greater threat than swap and drop attacks. The robustness of different models can be ordered as word-only $>$ word+char $>$ char-only $\\sim $ word-piece, and the efficacy of different attacks as add $>$ key $>$ drop $>$ swap.\nNext, we scrutinize the effectiveness of defense methods when faced against adversarially chosen attacks. Clearly from table 3 , DA and Adv are not effective in this case. We observed that despite a low training error, these models were not able to generalize to attacks on newer words at test time. ATD spell corrector is the most effective on keyboard attacks, but performs poorly on other attack types, particularly the add attack strategy.\nThe ScRNN model with pass-through backoff offers better protection, bringing back the adversarial accuracy within $5\\%$ range for the swap attack. It is also effective under other attack classes, and can mitigate the adversarial effect in word-piece models by $21\\%$ , character-only models by $19\\%$ , and in word, and word+char models by over $4.5\\%$ . This suggests that the direct training signal of word error correction is more effective than the indirect signal of sentiment classification available to DA and Adv for model robustness.\nWe observe additional gains by using background models as a backoff alternative, because of its lower word error rate (WER), especially, under the swap and drop attacks. However, these gains do not consistently translate in all other settings, as lower WER is necessary but not sufficient. Besides lower error rate, we find that a solid defense should furnish the attacker the fewest options to attack, i.e. it should have a low sensitivity.\nAs we shall see in section § \"Understanding Model Sensitivity\" , the backoff neutral variation has the lowest sensitivity due to mapping UNK predictions to a fixed neutral word. Thus, it results in the highest robustness on most of the attack types for all four model classes.\nTable 4 shows the accuracy of BERT on 200 examples from the dev set of the MRPC paraphrase detection task under various attack and defense settings. We re-trained the ScRNN model variants on the MRPC training set for these experiments. Again, we find that simple 1-2 character attacks can bring down the accuracy of BERT significantly ( $89\\%$ to $31\\%$ ). Word recognition models can provide an effective defense, with both our pass-through and neutral variants recovering most of the accuracy. While the neutral backoff model is effective on 2-char attacks, it hurts performance in the no attack setting, since it incorrectly modifies certain correctly spelled entity names. Since the two variants are already effective, we did not train a background model for this task.\nBaseline defense strategies Two common methods for dealing with adversarial examples include: (1) data augmentation (DA) (Krizhevsky et al., 2012); and (2) adversarial training (Adv) (Goodfellow et al., 2014).",

        "question": "Is it necessary to require the ML model and the causal model agree on each other?",
        "answer": "Regarding whether it is necessary that the ML-model and the causal model agree on all observations, note that the paper already addresses this to some extent, for it says: “In future work both requirements can be loosened by adding probabilities to each. For the first, we can demand that both models are likely to agree on observations.”\n\nOf course this short comment leaves much to be determined. For example, if the causal model disagrees with the ML-model for some input-output pair, do we want to assume that at least one of them is correct? And if so, should it always be the same model? Or should we generalize such that both models come with probabilities which represent their uncertainty? The latter scenario would be most natural if both models were learnt entirely independently of each other, but that seems unrealistic (and inefficient). In fact, given that ML-methods are influential precisely because they are so good at learning associations, it seems likely that we would use the function h as a constraint when learning the solutions to the causal model in the absence of interventions, and then — per construction — both models would agree on all observations. I believe addressing these issues (and how to incorporate uncertainty more generally) merits a paper of its own. The reason is that otherwise one runs the risk of conflating conceptual and definitional issues with practical empirical issues.",
        "evidence": "Assume that we have an ML-model which implements the overall function h : R(I) → R(Y ), where I consists of all the input variables and Y is the single output variable. As mentioned, we also assume knowledge of a causal model M of the target domain (i.e., that part of the world which h is a model of). A first requirement is that such a causal model is consistent with the ML-model, meaning that they at least agree on how to classify all observations. A second requirement that is helpful given the conceptual nature of our analysis is that the endogenous variables I suffice to obtain deterministic causal knowledge of the target domain. Technically this means that there are only two kinds of endogenous variables: those which are determined directly by the unobserved exogenous variables, and those which are determined entirely by members of I. In future work both requirements can be loosened by adding probabilities to each. For the first, we can demand that both models are likely to agree on observations. For the second, we can add new exogenous variables and a probability distribution over them, which give us probabilistic causal models. These allow for probabilistic generalizations of all the definitions here presented.\neither has a unique single exogenous parent U i ∈ U or no exogenous parents, and for all i ∈ R(I), y ∈ R(Y ):\nAs knowledge of the causal model is hard to come by many approaches to action-guiding explanations ignore it entirely and assume that the input variables are causally independent.\nDefinition 4 A causal model M that agrees with h satisfies Independence if for each I a , I b ∈ I, I a is not a parent of I b .\nObviously Independence rarely holds, and thus any account of action-guiding explanation that depends on it is limited. Although this limitation is recognized, this paper offers several results that formally characterize how extreme this limitation is. Simply put, under Independence a variety of very different causal notions become indistinguishable from each other. This holds for notions of sufficient explanation, counterfactual explanations, and various notions of actual causation.\nBecause of this limitation, work on action-guiding explanations in XAI has failed to take up the most relevant lesson that the literature on causation has to offer, namely that to give a causal explanation of an outcome is to give actual causes of that outcome. An additional reason for this oversight is that the precise relation between explanation and prediction has been the subject of much debate in the history of philosophy of science.\nPrediction in its most natural application is a forward-looking notion, meaning one predicts an event before it takes place. Explanation on the other hand is a backward-looking notion, meaning that one explains an event after it has happened. Yet as many papers on XAI clearly illustrate, explanations about past events are often required precisely to inform predictions about future events. Therefore a suitable notion of causal explanation, and thus also of actual causation, needs to specify how it relates to predictions. Given the tumultuous history that this relation has in the philosophy literature, it has been duly neglected in the philosophical work on causation, thereby obscuring the importance of causation for the practical goals that XAI is concerned with. forms a notable exception!) 2 This paper corrects this by developing an account of causal explanation that shows both how it is connected to actual causation and how it can lead to action-guiding predictions.\nSimply put, the goal of this paper is to upgrade the formalization of Woodward's influential philosophical account of causal explanation described below with the most recent insights from the causation literature, whilst also keeping track of the action-guiding demands that are prevalent in XAI.\nPut differently, my idea is that one ought to be able to associate with any successful explanation a hypothetical or counterfactual experiment that shows us that and how manipulation of the factors mentioned in the explanation (the explanans, as philosophers call it) would be a way of manipulating or altering the phenomenon explained (the explanandum). Put in still another way, an explanation ought to be such that it can be used to answer what I call a what-if-things-had-been-different question: the explanation must enable us to see what sort of difference it would have made for the explanandum if the factors cited in the explanans had been different in various possible ways.\nA crucial novel element of my account is the addition that a successful explanation must also be explicit about those factors that may not be manipulated for the explanation to hold, i.e., it must state which variables are to be safeguarded from interventions. Importantly, this is distinct from stating which variables must be held fixed at their actual values, for to hold variables fixed in fact means to intervene on them.\nThe following example (modified from) is helpful for illustrating the various purposes that explanations can serve.\nExample 1 Consider a system for loan applications that is captured by a causal model such that\nwhere Y is a binary variable representing whether the loan is granted, X 1 is the applicant's income, and X 2 is the applicant's savings. Further, assume that the applicant's savings are determined by their initial deposit X 3 and their income in the following manner: X 2 = 3/10 • X 1 + X 3 . It is also the case that people with high savings take out a safety deposit box (X 4 ) at the bank: X 4 = X 2 > 1, 000, 000.\nStandard predictions in ML take place on the first rung of Pearl's causal ladder, namely that of observations. For example, an ML-model might pick up on the fact that all observed loan applicants who have a safety deposit box (X 4 = 1) also get a loan (Y = 1), and thus could predict that an applicant who has a safety deposit box will get a loan, i.e., it might learn a function so that h(x 1 , x 2 , x 3 , 1) = 1 for all values x 1 , x 2 , x 3 . In terms of the causal model, it is indeed the case that refer to as an anchor, which they interpret as a sufficient explanation of the outcome. Yet clearly such observational explanations are not a good guide towards action, for it would be absurd to recommend to someone to take out a safety deposit box so that their loan application is approved. This point can be brought out by making use of the second rung of the ladder, namely that of interventions: an applicant who takes out a safety deposit box as the result of being advised to do so will not necessarily get a loan:\nIn the same manner, interventions can be used to offer advice that is a good guide towards action, for example by telling an applicant that if they manage to obtain savings of 45, 001 then they are guaranteed to get a loan:\nIn future work both requirements can be loosened by adding probabilities to each. For the first, we can demand that both models are likely to agree on observations. For the second, we can add new exogenous variables and a probability distribution over them, which give us probabilistic causal models. These allow for probabilistic generalizations of all the definitions here presented",

        "answer": "Cyberbullying has been defined by the National Crime Prevention Council as the use of the Internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person.",
        "evidence": "Cyberbullying has been defined by the National Crime Prevention Council as the use of the Internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person. Various studies have estimated that between to 10% to 40% of internet users are victims of cyberbullying BIBREF0 . Effects of cyberbullying can range from temporary anxiety to suicide BIBREF1 . Many high profile incidents have emphasized the prevalence of cyberbullying on social media. Most recently in October 2017, a Swedish model Arvida Byström was cyberbullied to the extent of receiving rape threats after she appeared in an advertisement with hairy legs.\nDetection of cyberbullying in social media is a challenging task. Definition of what constitutes cyberbullying is quite subjective. For example, frequent use of swear words might be considered as bullying by the general population. However, for teen oriented social media platforms such as Formspring, this does not necessarily mean bullying (Table TABREF9 ). Across multiple SMPs, cyberbullies attack victims on different topics such as race, religion, and gender. Depending on the topic of cyberbullying, vocabulary and perceived meaning of words vary significantly across SMPs. For example, in our experiments we found that for word `fat', the most similar words as per Twitter dataset are `female' and `woman' (Table TABREF23 ). However, other two datasets do not show such particular bias against women. This platform specific semantic similarity between words is a key aspect of cyberbullying detection across SMPs. Style of communication varies significantly across SMPs. For example, Twitter posts are short and lack anonymity. Whereas posts on Q&A oriented SMPs are long and have option of anonymity (Table TABREF7 ). Fast evolving words and hashtags in social media make it difficult to detect cyberbullying using swear word list based simple filtering approaches. The option of anonymity in certain social networks also makes it harder to identify cyberbullying as profile and history of the bully might not be available.\nPast works on cyberbullying detection have at least one of the following three bottlenecks. First (Bottleneck B1), they target only one particular social media platform. How these methods perform across other SMPs is unknown. Second (Bottleneck B2), they address only one topic of cyberbullying such as racism, and sexism. Depending on the topic, vocabulary and nature of cyberbullying changes. These models are not flexible in accommodating changes in the definition of cyberbullying. Third (Bottleneck B3), they rely on carefully handcrafted features such as swear word list and POS tagging. However, these handcrafted features are not robust against variations in writing style. In contrast to existing bottlenecks, this work targets three different types of social networks (Formspring: a Q&A forum, Twitter: microblogging, and Wikipedia: collaborative knowledge repository) for three topics of cyberbullying (personal attack, racism, and sexism) without doing any explicit feature engineering by developing deep learning based models along with transfer learning.\nWe experimented with diverse traditional machine learning models (logistic regression, support vector machine, random forest, naive Bayes) and deep neural network models (CNN, LSTM, BLSTM, BLSTM with Attention) using variety of representation methods for words (bag of character n-gram, bag of word unigram, GloVe embeddings, SSWE embeddings). Summary of our findings and research contributions is as follows.\nCyberbullying has been defined by the National Crime Prevention Council as the use of the Internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person.",

        "evidence": "NLG is the process of automatically generating coherent NL text from non-linguistic data BIBREF0. Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans. The version of LD2NL used in this paper, all experimental results will be publicly available.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL.",

The data was recorded under a partnership between the AVENUE project, funded by the US National Science Foundation at Carnegie Mellon University, the Chilean Ministry of Education (Mineduc), and the Instituto de Estudios Indígenas at Universidad de La Frontera, originally spanning 170 hours of audio. We have recently cleaned the data and are releasing it publicly for the first time (although it has been shared with individual researchers in the past) along with NLP baselines.\nThe recordings were transcribed and translated into Spanish at the Instituto de Estudios Indígenas at Universidad de La Frontera. The corpus covers three dialects of Mapudungun: about 110 hours of Nguluche, 20 hours of Lafkenche and 10 hours of Pewenche. The three dialects are quite similar, with some minor semantic and phonetic differences. The fourth traditionally distinguished dialect, Huilliche, has several grammatical differences from the other three and is classified by Ethnologue as a separate language, iso 639-3: huh, and as nearly extinct.\nThe recordings are restricted to a single domain: primary, preventive, and treatment health care, including both Western and Mapuche traditional medicine. The recording sessions were conducted as interactive conversations so as to be natural in Mapuche culture, and they were open-ended, following an ethnographic approach. The interviewer was trained in these methods along with the use of the digital recording systems that were available at the time. We also followed human subject protocol. Each person signed a consent form to release the recordings for research purposes and the data have been accordingly anonymized. Because Machi (traditional Mapuche healers) were interviewed, we asked the transcribers to delete any culturally proprietary knowledge that a Machi may have revealed during the conversation. Similarly, we deleted any names or any information that may identify the participants.\nThe corpus is culturally relevant because it was created by Mapuche people, using traditional ways of relating to each other in conversations. They discussed personal experiences with primary health care in the traditional Mapuche system and the Chilean health care system, talking about illnesses and the way they were cured. The participants ranged from 16 years old to 100 years old, almost in equal numbers of men and women, and they were all native speakers of Mapudungun.\nWe also moved the boundaries of the turns to standardize the amount of leading and trailing silence in each turn.

It was supposed that if expressions from the same similarity set co-occur in the same document then their contribution into the document's topics is really more than it is presented with their frequencies, therefore their frequencies should be increased. In such an approach, the algorithm can \"see\" similarities between different multiword expressions with the same component word.\nIn our approach, at first, we include related single words and phrases from a thesaurus such as WordNet or EuroVoc in these similarity sets. Then, we add preliminarily extracted ngrams into these sets and, this way, we use two different sources of external knowledge. We use the same LDA-SIM algorithm as described in BIBREF16 but study what types of semantic relations can be introduced into such similarity sets and be useful for improving topic models. The pseudocode of LDA-SIM algorithm is presented in Algorithm SECREF3 , where INLINEFORM0 is a similarity set, expressions in similarity sets can comprise single words, thesaurus phrases or generated noun compounds.\nWe can compare this approach with the approaches applying the generalized Polya urn model BIBREF8 , BIBREF9 , BIBREF10 .

        "evidence": "The SemEval-2010 benchmark dataset BIBREF0 is composed of 244 scientific articles collected from the ACM Digital Library (conference and workshop papers). The input papers ranged from 6 to 8 pages and were converted from PDF format to plain text using an off-the-shelf tool. The only preprocessing applied is a systematic dehyphenation at line breaks and removal of author-assigned keyphrases. Scientific articles were selected from four different research areas as defined in the ACM classification, and were equally distributed into training (144 articles) and test (100 articles) sets. Gold standard keyphrases are composed of both author-assigned keyphrases collected from the original PDF files and reader-assigned keyphrases provided by student annotators.\nLong documents such as those in the SemEval-2010 benchmark dataset are notoriously difficult to handle due to the large number of keyphrase candidates (i.e. phrases that are eligible to be keyphrases) that the systems have to cope with BIBREF6 . Furthermore, noisy textual content, whether due to format conversion errors or to unusable elements (e.g. equations), yield many spurious keyphrase candidates that negatively affect keyphrase extraction performance. This is particularly true for systems that make use of core NLP tools to select candidates, that in turn exhibit poor performance on degraded text. Filtering out irrelevant text is therefore needed for addressing these issues.\nIn this study, we concentrate our effort on re-assessing keyphrase extraction performance on three increasingly sophisticated levels of document preprocessing described below.\nTable shows the average number of sentences and words along with the maximum possible recall for each level of preprocessing. The maximum recall is obtained by computing the fraction of the reference keyphrases that occur in the documents. We observe that the level 2 preprocessing succeeds in eliminating irrelevant text by significantly reducing the number of words (-19%) while maintaining a high maximum recall (-2%). Level 3 preprocessing drastically reduce the number of words to less than a quarter of the original amount while interestingly still preserving high recall.\nTable 1 shows the average number of sentences and words along with the maximum possible recall for each level of preprocessing.

        "evidence": "",
        "answer": "In finance, a bond is a type of security under which the issuer (debtor) owes the holder (creditor) a debt, and is obliged – depending on the terms – to provide cash flow to the creditor (e.g. repay the principal (i.e. amount borrowed) of the bond at the maturity date as well as interest (called the coupon) over a specified amount of time).The timing and the amount of cash flow provided varies, depending on the economic value that is emphasized upon, thus giving rise to different types of bonds. The interest is usually payable at fixed intervals: semiannual, annual, and less often at other periods. Thus, a bond is a form of loan or IOU. Bonds provide the borrower with external funds to finance long-term investments or, in the case of government bonds, to finance current expenditure.\n\nBonds and stocks are both securities, but the major difference between the two is that (capital) stockholders have an equity stake in a company (i.e. they are owners), whereas bondholders have a creditor stake in a company (i.e. they are lenders). As creditors, bondholders have priority over stockholders. This means they will be repaid in advance of stockholders, but will rank behind secured creditors, in the event of bankruptcy. Another difference is that bonds usually have a defined term, or maturity, after which the bond is redeemed, whereas stocks typically remain outstanding indefinitely. An exception is an irredeemable bond, which is a perpetuity, that is, a bond with no maturity. Certificates of deposit (CDs) or short-term commercial paper are classified as money market instruments and not bonds: the main difference is the length of the term of the instrument.\n\nThe most common forms include municipal, corporate, and government bonds. Very often the bond is negotiable, that is, the ownership of the instrument can be transferred in the secondary market. This means that once the transfer agents at the bank medallion-stamp the bond, it is highly liquid on the secondary market. The price of a bond in the secondary market may differ substantially from the principal due to various factors in bond valuation.",

        "answer": "Yes, they do.",
        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nWe also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English.",

        "evidence": "Word embeddings are low-dimensional, dense vector representations that capture semantic properties of words. Recently, they have gained tremendous popularity in Natural Language Processing (NLP) and have been used in tasks as diverse as text similarity BIBREF0 , part-of-speech tagging BIBREF1 , sentiment analysis BIBREF2 , and machine translation BIBREF3 . Although word embeddings are widely used across NLP, their stability has not yet been fully evaluated and understood. In this paper, we explore the factors that play a role in the stability of word embeddings, including properties of the data, properties of the algorithm, and properties of the words. We find that word embeddings exhibit substantial instabilities, which can have implications for downstream tasks.\nUsing the overlap between nearest neighbors in an embedding space as a measure of stability (see sec:definingStability below for more information), we observe that many common embedding spaces have large amounts of instability. For example, Figure FIGREF1 shows the instability of the embeddings obtained by training word2vec on the Penn Treebank (PTB) BIBREF4 . As expected, lower frequency words have lower stability and higher frequency words have higher stability. What is surprising however about this graph is the medium-frequency words, which show huge variance in stability. This cannot be explained by frequency, so there must be other factors contributing to their instability.\nIn the following experiments, we explore which factors affect stability, as well as how this stability affects downstream tasks that word embeddings are commonly used for. To our knowledge, this is the first study comprehensively examining the factors behind instability.\nIn this paper, we explore the factors that play a role in the stability of word embeddings, including properties of the data, properties of the algorithm, and properties of the words.

        "question": "In the exploration, how does the agent identify a bottleneck in the game?",
        "answer": "They set a patience parameter and if the agent has not seen a higher score in patience steps, the agent assumes it has been limited by a bottleneck.",
        "evidence": "In this section, we describe methods to explore combinatorially sized action spaces such as text-games—focusing especially on methods that can deal with their inherent bottleneck structure. We first describe our method that explicitly attempts to detect bottlenecks and then describe how an exploration algorithm such as Go Explore BIBREF9 can leverage knowledge graphs.\nKG-A2C-chained An example of a bottleneck can be seen in Figure FIGREF1. We extend the KG-A2C algorithm as follows. First, we detect bottlenecks as states where the agent is unable to progress any further. We set a patience parameter and if the agent has not seen a higher score in patience steps, the agent assumes it has been limited by a bottleneck. Second, when a bottleneck is found, we freeze the policy that gets the agent to the state with the highest score. The agent then begins training a new policy from that particular state.\nSimply freezing the policy that led to the bottleneck, however, can potentially result in a policy one that is globally sub-optimal. We therefore employ a backtracking strategy that restarts exploration from each of the $n$ previous steps—searching for a more optimal policy that reaches that bottleneck. At each step, we keep track of a buffer of $n$ states and admissible actions that led up to that locally optimal state. We force the agent to explore from this state to attempt to drive it out of the local optima. If it is further unable to find itself out of this local optima, we refresh the training process again, but starting at the state immediately before the agent reaches the local optima. If this continues to fail, we continue to iterate through this buffer of seen states states up to that local optima until we either find a more optimal state or we run out of states to refresh from, in which we terminate the training algorithm.\nKG-A2C-Explore Go-Explore BIBREF9 is an algorithm that is designed to keep track of sub-optimal and under-explored states in order to allow the agent to explore upon more optimal states that may be a result of sparse rewards. The Go-Explore algorithm consists of two phases, the first to continuously explore until a set of promising states and corresponding trajectories are found on the basis of total score, and the second to robustify this found policy against potential stochasticity in the game. Promising states are defined as those states when explored from will likely result in higher reward trajectories. Since the text games we are dealing with are mostly deterministic, with the exception of Zork in later stages, we only focus on using Phase 1 of the Go-Explore algorithm to find an optimal policy. BIBREF10 look at applying Go-Explore to text-games on a set of simpler games generated using the game generation framework TextWorld BIBREF1. Instead of training a policy network in parallel to generate actions used for exploration, they use a small set of “admissible actions”—actions guaranteed to change the world state at any given step during Phase 1—to explore and find high reward trajectories. This space of actions is relatively small (of the order of $10^2$ per step) and so finding high reward trajectories in larger action-spaces such as in Zork would be infeasible\nGo-Explore maintains an archive of cells—defined as a set of states that map to a single representation—to keep track of promising states. BIBREF9 simply encodes each cell by keeping track of the agent's position and BIBREF10 use the textual observations encoded by recurrent neural network as a cell representation. We improve on this implementation by training the KG-A2C network in parallel, using the snapshot of the knowledge graph in conjunction with the game state to further encode the current state and use this as a cell representation. At each step, Go-Explore chooses a cell to explore at random (weighted by score to prefer more advanced cells). The KG-A2C will run for a number of steps, starting with the knowledge graph state and the last seen state of the game from the cell. This will generate a trajectory for the agent while further training the KG-A2C at each iteration, creating a new representation for the knowledge graph as well as a new game state for the cell. After expanding a cell, Go-Explore will continue to sample cells by weight to continue expanding its known states. At the same time, KG-A2C will benefit from the heuristics of selecting preferred cells and be trained on promising states more often.\nWe set a patience parameter and if the agent has not seen a higher score in patience steps, the agent assumes it has been limited by a bottleneck.",

        "answer": "We assume that the two clusters you refer to with the same tetrad constraints are \\{ X_1, X_2, X_3 \\} and \\{ X_7, X_8, X_9 \\} - as seen in Fig. 2b, the cluster \\{ X_4, X_5, X_6 \\} does not have the same tetrad constraints.\nIf this interpretation is correct, then you are right, the algorithm can pick either cluster (e.g., selecting between the two at random), or we could have opted to select all clusters at each step. If we instead picked \\{ X_7, X_8, X_9 \\}, the initial ordering between clusters would be different, but the ordered clustering after Phase 2 - the “merging” step in Algorithm 3 - would be the same, leading to the same final result.\nWe will clarify that this “tie-breaking” does not affect the final result. The true graph used in our examples is given in Fig 3c as the final output of the algorithm; we will move this to come before Fig 2.",
        "evidence": "Our algorithm, presented in Algorithm 1, consists of three stages. As is common in causal structure learning, we present our algorithm with implementation details of hypothesis testing abstracted away. In particular, we will assume access to two subroutines, whose implementation details will be given in Section 4.1.\nThe first subroutine tests H ci (X j , X A | X B ), which denotes the null hypothesis that X j and X A are conditionally independent given X B . The second subroutine tests H vt (X A , X B ), which denotes the null hypothesis that all tetrads of Σ A,B vanish.\nIn the first stage (Algorithm 2, see also Fig.), we identify clusters of observed variables with the same latent parent. However, note that since this stage only identifies leaves with the same latent parent, it is not guaranteed to identify all nodes with the same latent parent. This stage simultaneously recovers an ordering over these clusters. Thus, in the second stage (Algorithm 3, see also Fig.), we iterate over pairs of clusters output from the first stage, identify pairs of clusters\nRemaining nodes\nFigure: Phase 1: Let the true LFCM be the graph in Fig.). In our algorithm's first phase (see Algorithm 2) we perform the following steps: (a) Compute tetrad scores between all pairs of nodes. (b) For each pair of nodes, test the null hypothesis that all tetrads are zero. Construct a graph with the edge i − j for any pair of nodes where we do not reject the null hypothesis. (c) Extract a clique from this graph to be a cluster (e.g., by picking the largest clique with arbitrary tie breaking), remove these nodes and repeat with remaining nodes.\nwith the same latent parent, and merge them, while leaving the ordering of the clusters intact. In the third stage (Algorithm 4, see also Fig.), we use the clustering and ordering information discovered in the previous two stages to learn a DAG over both latent and observed variables. In particular, given a node X j in cluster C j which comes before the cluster C i in our ordering, we wish to determine whether X j has an edge to the associated latent variable L i . By Assumption 2, this can be accomplished by checking partial correlations between X j and the nodes in C i . These stages compose a consistent algorithm, as established in the following theorem and proven in Appendix B.\nIn Section 3, we have already discussed the importance of the first three structural assumptions from Definition 1. In Appendix C, we show how our algorithm fails under a violation of the double-parent assumption.\nTheorem 2 Let G be a linear LFCM and let X ∈ R n×p be a matrix of samples of the observed variables X 1 , . . . , X p . Then Algorithm 1 is consistent under Assumptions 1, 2, and 3, i.e., as n → ∞, we have P( Ĝ = G) → 1.\nNext, we outline the complexity of our algorithm, using placeholders for the complexities of hypothesis tests in order to keep our results general. Let f (d, n) denote the cost of performing the hypothesis test H vt on d statistics from n samples, when all sufficient statistics are pre-computed. Let g(p) denote the complexity of an algorithm used to find a clique in a graph on p nodes. While finding the largest clique in a graph is in general NP-hard, we can avoid this complexity, since the consistency of our algorithm does not rely on picking the largest clique at each step, only a clique of 3 or more nodes (picking larger cliques is simply a tool for improving statistical accuracy).\nIn the following, let M be the maximum size of any returned cluster, and let K be the number of clusters discovered by the algorithm. By definition, M ≤ p and K ≤ p, so replacing these quantities by p gives complexities that are only in terms of the known problem parameters. However, such upper bounds can be highly pessimistic. If the true graph has few nodes per cluster, or a small number of latent nodes, then with enough samples, M and K will also be small, respectively.  Proof (a) Computing all tetrads and their associated p-values is O(p 4 ). In each round, we perform O(p 2 ) hypothesis tests, each on O(p 2 ) statistics, so that the complexity at each round is O(p 2 f (p 2 , n)). After performing these tests, we identify the largest clique in a graph of O(p) nodes, so that the total run time per round is O(p 2 f (p 2 , n) + g(p)). At most p rounds are required, resulting in the stated complexity.\n(b) We must check O(p 2 ) pairs of clusters for whether or not they should be merged, and the maximum size of the union of any such pair is O(M ). To check whether O(M ) nodes belong to the same cluster, we require a hypothesis test on O(M 4 ) statistics, so that this step takes O(p 2 f (M 4 , n)).\n(c) We perform O(pK) hypothesis tests, each based on O(M ) partial correlations.\nAssume that we use the Sidak adjustment procedure explained in the next section (so that f (d, n) = O(d)), and a greedy algorithm for picking cliques (so that g(p) = p 3 ). Then, replacing K and M by p, we have that Algorithm 2 takes O(p 5 ), Algorithm 3 takes O(p 6 ), and Algorithm 4 takes O(p 3 ), so that the overall complexity of our algorithm is at most O(p 6 ). Even in this pessimistic analysis, this complexity is relatively low for causal structure learning, which is known to be NPhard in general, and for which variants of the best-known algorithms, such as PC and GES, typically have complexity O(p d+2 ), where d is the maximum in-degree of the graph.\nWe evaluate our algorithm in two settings. First, we evaluate in a purely synthetic setting, which allows us to generate SCMs which exactly match our proposed model. Then, we evaluate in a semisynthetic setting, modifying real data to more closely match our proposed model while demonstrating that our approach has promise in real-world biological settings.\nFigure 2: Phase 1: Let the true LFCM be the graph in Fig. 3(c). In our algorithm’s first phase (see Algorithm 2) we perform the following steps: (a) Compute tetrad scores between all pairs of nodes. (b) For each pair of nodes, test the null hypothesis that all tetrads are zero. Construct a graph with the edge i − j for any pair of nodes where we do not reject the null hypothesis. (c) Extract a clique from this graph to be a cluster (e.g., by picking the largest clique with arbitrary tie breaking),\nremove these nodes and repeat with remaining nodes.****Figure 3: Phases 2 and 3.

        "question": "When and where was Nero born?",
        "evidence": "Nero Claudius Caesar Augustus Germanicus (/ˈnɪəroʊ/ NEER-oh; born Lucius Domitius Ahenobarbus; 15 December AD 37 – 9 June AD 68), was the fifth Roman emperor and final emperor of the Julio-Claudian dynasty, reigning from AD 54 until his death in AD 68. He was adopted by the Roman emperor Claudius at the age of 13 and succeeded him on the throne. Nero was popular with the members of his Praetorian Guard and lower-class commoners in Rome and its provinces, but he was deeply resented by the Roman aristocracy. Most contemporary sources describe him as tyrannical, self-indulgent, and debauched. After being declared a public enemy by the Roman Senate, he committed suicide at age 30.\n\nNero was born at Antium in AD 37, the son of Gnaeus Domitius Ahenobarbus and Agrippina the Younger, a great-granddaughter of the emperor Augustus. When Nero was two years old, his father died. His mother married the emperor Claudius, who eventually adopted Nero as his heir; when Claudius died in AD 54, Nero became emperor with the support of the Praetorian Guard and the Senate. In the early years of his reign Nero was advised and guided by his mother Agrippina, his tutor Seneca the Younger, and his praetorian prefect Sextus Afranius Burrus, but he soon sought to rule independently and to rid himself of restraining influences. His power struggle with his mother was eventually resolved when he had her murdered. Roman sources also implicate Nero in the deaths of his wife Claudia Octavia – supposedly so that he could marry Poppaea Sabina – and of his step brother Britannicus.\n\nNero's practical contributions to Rome's governance focused on diplomacy, trade, and culture. He ordered the construction of amphitheaters, and promoted athletic games and contests. He also made public appearances as an actor, poet, musician, and charioteer, which scandalised his aristocratic contemporaries as these occupations were usually the domain of slaves, public entertainers and infamous persons. The provision of such entertainments made Nero popular among lower-class citizens, but his performances undermined the Imperial dignity. The costs involved were borne by local elites either directly or through taxation, and were much resented.\n\nDuring Nero's reign, the general Corbulo fought the Roman–Parthian War of 58–63, and made peace with the hostile Parthian Empire. The Roman general Suetonius Paulinus quashed a major revolt in Britain led by the Iceni's queen Boudica. The Bosporan Kingdom was briefly annexed to the empire, and the First Jewish–Roman War began. When the Roman senator Vindex rebelled, with support from the eventual Roman emperor Galba, Nero was declared a public enemy and condemned to death in absentia. He fled Rome, and on 9 June AD 68 he committed suicide. His death sparked a brief period of civil war known as the Year of the Four Emperors.\n\nMost Roman sources offer overwhelmingly negative assessments of his personality and reign. The historian Tacitus claims the Roman people thought him compulsive and corrupt. Suetonius tells that many Romans believed that the Great Fire of Rome was instigated by Nero to clear land for his planned \"Golden House\". Tacitus claims that Nero seized Christians as scapegoats for the fire and had them burned alive, seemingly motivated not by public justice but by personal cruelty. Some modern historians question the reliability of the ancient sources on Nero's tyrannical acts, considering his popularity among the Roman commoners. In the eastern provinces of the Empire, a popular legend arose that Nero had not died and would return. After his death, at least three leaders of short-lived, failed rebellions presented themselves as \"Nero reborn\" in order to gain popular support.\n\nEarly life\nNero was born Lucius Domitius Ahenobarbus on 15 December 37 AD in Antium (modern Anzio).: 87  He was an only-child, the son of the politician Gnaeus Domitius Ahenobarbus and Agrippina the Younger. His mother Agrippina was the sister of the third Roman emperor Caligula.: 5  Nero was also the great-great-grandson of former emperor Augustus (descended from Augustus' only daughter, Julia).: 2 \n\nThe ancient biographer Suetonius, who was critical of Nero's ancestors, wrote that emperor Augustus had reproached Nero's grandfather for his unseemly enjoyment of violent gladiator games. According to Jürgen Malitz, Suetonius tells that Nero's father was known to be \"irascible and brutal\", and that both \"enjoyed chariot races and theater performances to a degree not befitting their position\".: 3  Suetonius also mentions that when Nero's father Domitius was congratulated by his friends for the birth of his son, he replied that any child born to him and Agrippina would have a detestable nature and become a public danger.\n\nDomitius died in 40 AD. A few years before his father's death, his father was involved in a serious political scandal.: 3  His mother and his two surviving sisters, Agrippina and Julia Livilla, were exiled to a remote island in the Mediterranean Sea.: 4  His mother was said to have been exiled for plotting to overthrow the emperor Caligula. Nero's inheritance was taken from him, and he was sent to live with his paternal aunt Domitia Lepida the Younger, the mother of later emperor Claudius's third wife, Messalina.: 11 \n\n\nAn aureus of Nero and his mother, c. 54. Caption: NERONIS CAES MATER AGRIPP. AVG. DIVI CLAVD. / NERONI CLAVD. DIVI F. CAES. AVG. GERM. IMP. TR. P. – EX SC\nAfter Caligula's death, Claudius became the new Roman Emperor. Nero's mother married Claudius in 49 AD, becoming his fourth wife. By February, 49 AD, his mother had persuaded Claudius to adopt her son Nero.\n\nAfter Nero's adoption by the emperor, \"Claudius\" became part of his name: Nero Claudius Caesar Drusus Germanicus. Claudius had gold coins issued to mark the adoption.: 119  Classics professor Josiah Osgood has written that \"the coins, through their distribution and imagery alike, showed that a new Leader was in the making.\": 231  However, David Shotter noted that, despite events in Rome, Nero's step-brother Britannicus was more prominent in provincial coinages during the early 50s.: 52 \n\nBust of Nero, National Museum in Oslo\nNero formally entered public life as an adult in 51 AD at approximately 14 years old.: 51  When he turned 16, Nero married Claudius' daughter (his step-sister), Claudia Octavia. Between the years 51 AD and 53 AD, he gave several speeches on behalf of various communities, including the Ilians; the Apameans (requesting a five-year tax reprieve after an earthquake); and the northern colony of Bologna, after their settlement had suffered a devastating fire.: 231 \n\nClaudius died in 54 AD; many ancient historians claim that he was poisoned by Agrippina. Shotter has written that \"Claudius' death in 54 AD has usually been regarded as an event hastened by Agrippina due to signs that Claudius was showing a renewed affection for his natural son\". He also notes that among ancient sources, the Roman historian Josephus was uniquely reserved in describing the poisoning as a rumor.: 53 \n\nContemporary sources differ in their accounts of the poisoning. Tacitus says that the poison-maker Locusta prepared the toxin, which was served to the Emperor by his servant Halotus. Tacitus also writes that Agrippina arranged for Claudius' doctor Xenophon to administer poison, in the event that the Emperor survived.: 53  Suetonius differs in some details, but also implicates Halotus and Agrippina. Like Tacitus, Cassius Dio writes that the poison was prepared by Locusta, but in Dio's account it is administered by Agrippina instead of Halotus. In Apocolocyntosis, Seneca the Younger does not mention mushrooms at all.: 54  Agrippina's involvement in Claudius' death is not accepted by all modern scholars.: 589 \n\nBefore Claudius' death, Agrippina had maneuvered to remove Claudius' sons' tutors in order to replace them with tutors that she had selected. She was also able to convince Claudius to replace two prefects of the Praetorian Guard (who were suspected of supporting Claudius' son) with Afranius Burrus (Nero's future guide).: 13  Since Agrippina had replaced the guard officers with men loyal to her, Nero was subsequently able to assume power without incident.: 417",

        "question": "Who invented scratching ?",
        "evidence": "Modern scratching techniques were made possible by the invention of direct-drive turntables, which led to the emergence of turntablism. Early belt-drive turntables were unsuitable for scratching since they had a slow start-up time, and they were prone to wear and tear and breakage, as the belt would break from backspinning or scratching. The first direct-drive turntable was invented by Shuichi Obata, an engineer at Matsushita (now Panasonic), based in Osaka, Japan. It eliminated belts, and instead employed a motor to directly drive a platter on which a vinyl record rests. In 1969, Matsushita released it as the SP-10, the first direct-drive turntable on the market, and the first in their influential Technics series of turntables.\n\nIn the 1970s, hip hop musicians and club DJs began to use this specialized turntable equipment to move the record back and forth, creating percussive sounds and effects–\"scratching\"–to entertain their dance floor audiences. Whereas the 1940s–1960s radio DJs had used back-cueing while listening to the sounds through their headphones, without the audience hearing, with scratching, the DJ intentionally lets the audience hear the sounds that are being created by manipulating the record on the turntable, by directing the output from the turntable to a sound reinforcement system so that the audience can hear the sounds. Scratching was developed by early hip hop DJs from New York City such as Grand Wizzard Theodore, who described scratching as, \"nothing but the back-cueing that you hear in your ear before you push it [the recorded sound] out to the crowd.\" He developed the technique when experimenting with the Technics SL-1200, a direct-drive turntable released by Matsushita in 1972 when he found that the motor would continue to spin at the correct RPM even if the DJ wiggled the record back and forth on the platter. Afrika Bambaataa made a similar discovery with the SL-1200 in the 1970s. The Technics SL-1200 went on to become the most widely used turntable for the next several decades.\n\nJamaican-born DJ Kool Herc, who immigrated to New York City, influenced the early development of scratching. Kool Herc developed break-beat DJing, where the breaks of funk songs—being the most danceable part, often featuring percussion—were isolated and repeated for the purpose of all-night dance parties. He was influenced by Jamaican dub music, and developed his turntable techniques using the Technics SL-1100, released in 1971, due to its strong motor, durability, and fidelity.\n\nAlthough previous artists such as writer and poet William S. Burroughs had experimented with the idea of manipulating a reel-to-reel tape manually to make sounds, as with his 1950s recording, \"Sound Piece\"), vinyl scratching as an element of hip hop pioneered the idea of making the sound an integral and rhythmic part of music instead of an uncontrolled noise. Scratching is related to \"scrubbing\" (in terms of audio editing and production) when the reels of an open reel-to-reel tape deck (typically 1/4 inch magnetic audiotape) are gently rotated back and forth while the playback head is live and amplified, to isolate a specific spot on the tape where an editing \"cut\" is to be made. In the 2010s, both scratching and scrubbing can be done on digital audio workstations (DAWs) which are equipped for these techniques.\n\n\nWhere It All Started\n\nDJ Sample of the song \"Where it All Started\"\nProblems playing this file? See media help.\nChristian Marclay was one of the earliest musicians to scratch outside hip hop. In the mid-1970s, Marclay used gramophone records and turntables as musical instruments to create sound collages. He developed his turntable sounds independently of hip hop DJs. Although he is little-known to mainstream audiences, Marclay has been described as \"the most influential turntable figure outside hip hop\" and the \"unwitting inventor of turntablism.\"\n\nIn 1981 Grandmaster Flash released the song \"The Adventures of Grandmaster Flash on the Wheels of Steel\" which is notable for its use of many DJ scratching techniques. It was the first commercial recording produced entirely using turntables. In 1982, Malcolm McLaren & the World's Famous Supreme Team released a single \"Buffalo Gals\", juxtaposing extensive scratching with calls from square dancing, and, in 1983, the EP, D'ya Like Scratchin'?, which is entirely focused on scratching. Another 1983 release to prominently feature scratching is Herbie Hancock's Grammy Award-winning single \"Rockit\". This song was also performed live at the 1984 Grammy Awards, and in the documentary film Scratch, the performance is cited by many 1980s-era DJs as their first exposure to scratching. The Street Sounds Electro compilation series which started in 1983 is also notable for early examples of scratching. Also, a notable piece was \"For A Few Dollars More\" by Bill Laswell-Michael Beinhorn band Material, released on 12\" single in Japan and containing scratch performed by Grand Mixer DXT, another pioneer of scratching.",

For POS INLINEFORM3 -grams we use cut-offs 10 for unigrams and 20 for bigrams and higher. For the Yahoo! and Amazon datasets we use cut-offs of INLINEFORM4 . The INLINEFORM5 -grams features are then also extracted using the hashing trick with the same cut-offs to reduce the final feature vector size when combined with other features. scikit-learn's BIBREF14 FeatureHasher is used with output vectors sizes of INLINEFORM6 INLINEFORM7 INLINEFORM8 for ngrams from INLINEFORM9 respectively and INLINEFORM10 INLINEFORM11 INLINEFORM12 are used for POS ngrams. We extract lexical and POS level Language model features based on external language models, namely sentence log probabilities, perplexities, and surprisal in units of bits. Building the language model and extracting the features is done by providing the path to the compiled binaries for kenlm BIBREF15 . Finally we extract N-gram Frequency Quantile Distribution features with the same cut-offs as in the bag of ngrams features, with 4 quantiles and an OOV quantile. NLTK BIBREF16 is used for tokenization and POS tagging.\nWe extracted two features that use a learned representation: Firstly, we get a sentence embedding feature that is built by averaging the word embeddings of an input sentence. Secondly, we extract a fastText representation using the fastText library with the same parameters as reported in Joulin et al. joulin2016bag.\nWe extract 5 Surface and Lexical features, namely sequence length in number of tokens, average word length, type-token ratio, and lexical to tokens ratio (ratio of adjectives, verbs, nouns, and adverbs to tokens).\nWe extracted two features that use a learned representation: Firstly, we get a sentence embedding feature that is built by averaging the word embeddings of an input sentence.

We expect kids to respect us, so the same holds good for us, try to behave with them the way you to see them behave with you. Try to dedicate a few hours to spend time with them, remember it's the quality and not the quantity that matters here. Try not to correct them for everything they do, and try to set a boundary on things you can let go of.

Previous versions of the theorem date back to 1811, but in its modern general form, this fundamental result in probability theory was precisely stated as late as 1920, thereby serving as a bridge between classical and modern probability theory.",
        "answer": "For example, suppose that a sample is obtained containing many observations, each observation being randomly generated in a way that does not depend on the values of the other observations, and that the arithmetic mean of the observed values is computed. If this procedure is performed many times, the central limit theorem says that the probability distribution of the average will closely approximate a normal distribution.\n\nThe central limit theorem has several variants. In its common form, the random variables must be independent and identically distributed (i.i.d.). In variants, convergence of the mean to the normal distribution also occurs for non-identical distributions or for non-independent observations, if they comply with certain conditions.\n\nThe earliest version of this theorem, that the normal distribution may be used as an approximation to the binomial distribution, is the de Moivre–Laplace theorem.",

At its peak, the islands had 175 residents. The population declined to 22 by 1953. The government evacuated most of the remaining residents to the mainland on 17 November 1953 because of increasingly extreme winter weather that left the island's ageing population cut off from emergency services.

        "answer": "CRISPR  (an acronym for clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. Hence these sequences play a key role in the antiviral (i.e. anti-phage) defense system of prokaryotes and provide a form of acquired immunity. CRISPR is found in approximately 50% of sequenced bacterial genomes and nearly 90% of sequenced archaea.\n\nCas9 (or \"CRISPR-associated protein 9\") is an enzyme that uses CRISPR sequences as a guide to recognize and cleave specific strands of DNA that are complementary to the CRISPR sequence. Cas9 enzymes together with CRISPR sequences form the basis of a technology known as CRISPR-Cas9 that can be used to edit genes within organisms. This editing process has a wide variety of applications including basic biological research, development of biotechnological products, and treatment of diseases. The development of the CRISPR-Cas9 genome editing technique was recognized by the Nobel Prize in Chemistry in 2020 which was awarded to Emmanuelle Charpentier and Jennifer Doudna.\n\nIn 2022, in a proceeding at the United States Patent and Trademark Office (interference 106,115), the Patent Trial and Appeal Board decided that the inventor for the US patent covering application of CRISPR-Cas9 in eukaryotic cells is Feng Zhang, a professor of the Broad Institute.",

It is a task on par with detecting plagiarism, something a non-trained person (or sometimes even a trained person) cannot easily accomplish. (Hence the need for the development of the field of stylometry in early Renaissance.) Be that as it may, we wanted to evaluate our model against humans to make sure that it is indeed outperforming them.\nWe designed an experiment to compare the performance of human judges to our best model, the temporal-linguistic confusion model. The task had to be simple enough so that human judges could attempt it with ease. For example, it would have been ludicrous to ask the judges to sort $11,224$ accounts into $5,612$ matching pairs.\nThus, we randomly selected 100 accounts from distinct users from our collection of $11,224$ accounts. A unique list of 10 candidate accounts was created for each of the 100 accounts. Each list contained the correct matching account mixed in with 9 other randomly selected accounts. The judges were then presented with the 100 accounts one at a time and asked to pick the correct matching account from the list of 10 candidate accounts. For simplicity, we did not ask the judges to do any ranking other than picking the one account that they thought matched the original account. We then measured the accuracy of the judges based on how many of the 100 accounts they correctly matched. We had our model do the exact same task with the same dataset. A random baseline model would have a one in ten chance of getting the correct answer, giving it an accuracy of $0.10$ .\nWe had a total of 3 English speaking human judges from Amazon Mechanical Turk (which is an tool for crowd-sourcing of human annotation tasks) . For each task, the judges were shown the link to one of the 100 account, and its 10 corresponding candidate account links. The judges were allowed to explore each of the accounts as much as they wanted to make their decision (since all these accounts were public, there were no privacy concerns).\nTable 5 shows the performance of each of the three human judges, our model and the random baseline. Since the task is so much simpler than pairing $11,224$ accounts, our combined confusion model had a much greater accuracy than reported in the last section. With an accuracy of $0.86$ , our model vastly outperformed even the best human judge, at $0.69$ . Overall, our model beat the average human performance by $0.26$ ( $0.86$ to $0.60$ respectively) which is a $43\\%$ relative (and $26\\%$ absolute) improvement.\nOverall, our model beat the average human performance by 0.26 (0.86 to 0.60 respectively) which is a 43% relative (and 26% absolute) improvement.",

        "question": "What are the two main perspectives for understanding the NMT model?",
        "answer": "The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors or hidden units. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models.",
        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors (Shi et al., 2016; Belinkov et al., 2017) or hidden units (Bau et al., 2019; Ding et al., 2017).

There is clear guidance on what to do depending on what type of bear you see: if it’s a black bear, make yourself loud and fight if necessary. If it’s a brown bear, lay down and cover your head. If it’s a polar bear, hope you updated your will recently. However, there is very little guidance on what not to do if you see a bear. Thankfully it is easy to provide guidance that applies to all bear types. First, do not attempt to hug the bear. While they do look fluffy and very much in need of a hug, bears highly value consent and will attempt to eat you if you ignore that. Next, do not invite a bear over for dinner. While some bears, black bears especially, may look like good dinner guests they are known for extremely rude eating habits and will likely dirty your house. Further, some types of bears might think that you are the menu. It is also not a good idea to challenge a bear to a game of basketball. Most bears are actually extremely adept at basketball, and this would likely hurt your ego considerably as they would dunk on you and then eat you as a celebration for winning.

For instance, BIBREF8 trained a series of bigram language models to quantify the violation of social norms in users' posts on an online community by leveraging cross-entropy value, or the deviation of word sequences predicted by the language model and their usage by the user. However, their models were trained on written-language instead of natural face-face dialog corpus. Another kind of social norm violation was examined by BIBREF10 , who developed a classifier to identify specific types of sarcasm in tweets. They utilized a bootstrapping algorithm to automatically extract lists of positive sentiment phrases and negative situation phrases from given sarcastic tweets, which were in turn leveraged to recognize sarcasm in an SVM classifier. However, no contextual information was considered in this work. BIBREF11 understood the nature of social norm violation in dialog by correlating it with associated observable verbal, vocal and visual cues. By leveraging their findings and statistical machine learning techniques, they built a computational model for automatic recognition. While they preserved short-term temporal contextual information in the model, this study avoided dealing with sparsity of the social norm violation phenomena by under-sampling the negative-class instances to make a balanced dataset.\nInteresting prior work on quantifying social norm violation has taken a heavily data-driven focus BIBREF8 , BIBREF9 .

The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and establish relationships between them. They state empirical facts that form a basis of precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, they are important fundamental laws of physics in general, and are applicable in other natural sciences.\n\nTraditionally, thermodynamics has recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law. A more fundamental statement was later labelled as the zeroth law, after the first three laws had been established.\n\nThe zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature: If two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.\n\nThe first law of thermodynamics states that, when energy passes into or out of a system (as work, heat, or matter), the system's internal energy changes in accordance with the law of conservation of energy.\n\nThe second law of thermodynamics states that in a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems never decreases. A common corollary of the statement is that heat does not spontaneously pass from a colder body to a warmer body.\n\nThe third law of thermodynamics states that a system's entropy approaches a constant value as the temperature approaches absolute zero. With the exception of non-crystalline solids (glasses), the entropy of a system at absolute zero is typically close to zero.\n\nThe first and second laws prohibit two kinds of perpetual motion machines, respectively: the perpetual motion machine of the first kind which produces work with no energy input, and the perpetual motion machine of the second kind which spontaneously converts thermal energy into mechanical work.",

        "evidence": "The past several years have witnessed a significant progress in Neural Machine Translation (NMT). Most NMT methods are based on the encoder-decoder architecture BIBREF0 , BIBREF1 , BIBREF2 and can achieve promising translation performance in a variety of language pairs BIBREF3 , BIBREF4 , BIBREF5 .\nHowever, recent studies BIBREF6 , BIBREF7 show that NMT often generates words that make target sentences fluent, but unfaithful to the source sentences. In contrast, traditional Statistical Machine Translation (SMT) methods tend to rarely make this kind of mistakes. Fig. 1 shows an example that NMT makes mistakes when translating the phrase “jinkou dafu xiahua (the sharp decline in imports)” and the phrase “maoyi shuncha (the trade surplus)”, but SMT can produce correct results when translating these two phrases. BIBREF6 argues that the reason behind this is the use of distributed representations of words in NMT makes systems often generate words that seem natural in the context, but do not reflect the content of the source sentence. Traditional SMT can avoid this problem as it produces the translations based on phrase mappings.\nTherefore, it will be beneficial to combine SMT and NMT to alleviate the previously mentioned problem. Actually, researchers have made some effective attempts to achieve this goal. Earlier studies were based on the SMT framework, and have been deeply discussed in BIBREF8 . Later, the researchers transfers to NMT framework. Specifically, coverage mechanism BIBREF9 , BIBREF10 , SMT features BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 and translation lexicons BIBREF6 , BIBREF16 , BIBREF17 have been fully explored. In contrast, phrase translation table, as the core of SMT, has not been fully studied. Recently, BIBREF18 and BIBREF19 explore the possibility of translating phrases in NMT. However, the “phrase” in their approaches are different from that used in phrase-based SMT. In BIBREF18 's models, the phrase pair must be a one-to-one mapping with a source phrase having a unique target phrase (named entity translation pairs). In BIBREF19 's models, the source side of a phrase pair must be a chunk. Therefore, it is still a big challenge to incorporate any phrase pair in the phrase table into NMT system to alleviate the unfaithfulness problem.\nIn this paper, we propose an effective method to incorporate a phrase table as recommendation memory into the NMT system. To achieve this, we add bonuses to the words in recommendation set to help NMT make better predictions. Generally, our method contains three steps. 1) In order to find out which words are worthy to recommend, we first derive a candidate target phrase set by searching the phrase table according to the input sentence. After that, we construct a recommendation word set at each decoding step by matching between candidate target phrases and previously translated target words by NMT. 2) We then determine the specific bonus value for each recommendable word by using the attention vector produced by NMT and phrase translation probability extracted from phrase table. 3) Finally we integrate the word bonus value into the NMT system to improve the final results.\nIn this paper, we make the following contributions:\n1) We propose a method to incorporate the phrase table as recommendation memory into NMT system. We design a novel approach to find from the phrase table the target words worthy of recommendation, calculate their recommendation scores and use them to promote NMT to make better predictions.\n2) Our empirical experiments on Chinese-English translation and English-Japanese translation tasks show the efficacy of our methods. For Chinese-English translation, we can obtain an average improvement of 2.23 BLEU points. For English-Japanese translation, the improvement can reach 1.96 BLEU points. We further find that the phrase table is much more beneficial than bilingual lexicons to NMT.\nGenerally, our method contains three steps. 1) In order to find out which words are worthy to recommend, we first derive a candidate target phrase set by searching the phrase table according to the input sentence.",

        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nWe found that EqEmbs provide better models when compared to existing word embedding approaches.",

        "answer": "Yes.",
        "evidence": "Most of the information humanity has gathered up to this point is stored in the form of plain text. Hence the task of teaching machines how to understand this data is of utmost importance in the field of Artificial Intelligence. One way of testing the level of text understanding is simply to ask the system questions for which the answer can be inferred from the text. A well-known example of a system that could make use of a huge collection of unstructured documents to answer questions is for instance IBM's Watson system used for the Jeopardy challenge BIBREF0 .\nCloze-style questions BIBREF2 , i.e. questions formed by removing a phrase from a sentence, are an appealing form of such questions (for example see Figure FIGREF1 ). While the task is easy to evaluate, one can vary the context, the question sentence or the specific phrase missing in the question to dramatically change the task structure and difficulty.\nOne way of altering the task difficulty is to vary the word type being replaced, as in BIBREF3 . The complexity of such variation comes from the fact that the level of context understanding needed in order to correctly predict different types of words varies greatly. While predicting prepositions can easily be done using relatively simple models with very little context knowledge, predicting named entities requires a deeper understanding of the context.\nAlso, as opposed to selecting a random sentence from a text as in BIBREF3 ), the question can be formed from a specific part of the document, such as a short summary or a list of tags. Since such sentences often paraphrase in a condensed form what was said in the text, they are particularly suitable for testing text comprehension BIBREF1 .\nAn important property of cloze-style questions is that a large amount of such questions can be automatically generated from real world documents. This opens the task to data-hungry techniques such as deep learning. This is an advantage compared to smaller machine understanding datasets like MCTest BIBREF4 that have only hundreds of training examples and therefore the best performing systems usually rely on hand-crafted features BIBREF5 , BIBREF6 .\nIn the first part of this article we introduce the task at hand and the main aspects of the relevant datasets.

        "evidence": "The scientific process by which the deep learning research community operates is guided by empirical studies that evaluate the relative quality of models. Complicating matters, the measured performance of a model depends not only on its architecture (and data), but it can strongly depend on hyperparameter values that affect learning, regularisation, and capacity. This hyperparameter dependence is an often inadequately controlled source of variation in experiments, which creates a risk that empirically unsound claims will be reported.\nIn this paper, we use a black-box hyperparameter optimisation technique to control for hyperparameter effects while comparing the relative performance of language modelling architectures based on LSTMs, Recurrent Highway Networks BIBREF0 and NAS BIBREF1 . We specify flexible, parameterised model families with the ability to adjust embedding and recurrent cell sizes for a given parameter budget and with fine grain control over regularisation and learning hyperparameters.\nOnce hyperparameters have been properly controlled for, we find that LSTMs outperform the more recent models, contra the published claims. Our result is therefore a demonstration that replication failures can happen due to poorly controlled hyperparameter variation, and this paper joins other recent papers in warning of the under-acknowledged existence of replication failure in deep learning BIBREF2 , BIBREF3 . However, we do show that careful controls are possible, albeit at considerable computational cost.\nSeveral remarks can be made in light of these results. First, as (conditional) language models serve as the central building block of many tasks, including machine translation, there is little reason to expect that the problem of unreliable evaluation is unique to the tasks discussed here. However, in machine translation, carefully controlling for hyperparameter effects would be substantially more expensive because standard datasets are much larger. Second, the research community should strive for more consensus about appropriate experimental methodology that balances costs of careful experimentation with the risks associated with false claims. Finally, more attention should be paid to hyperparameter sensitivity. Models that introduce many new hyperparameters or which perform well only in narrow ranges of hyperparameter settings should be identified as such as part of standard publication practice.\nIn this paper, we use a black-box hyperparameter optimisation technique to control for hyperparameter effects while comparing the relative performance of language modelling architectures based on LSTMs, Recurrent Highway Networks and NAS.",

        "evidence": "Despite the American public's increasing acceptance of LGBTQ people and recent legal successes, LGBTQ individuals frequently remain the targets of hate and violence BIBREF0, BIBREF1, BIBREF2. At the core of this issue is dehumanization, “the act of perceiving or treating people as less than human” BIBREF3, a process that heavily contributes to extreme intergroup bias BIBREF4. Language is central to studying this phenomenon; like other forms of bias BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, dehumanizing attitudes are expressed through subtle linguistic manipulations, even in carefully-edited texts. It is crucial to understand the use of such linguistic signals in mainstream media, as the media's representation of marginalized social groups has far-reaching implications for social acceptance, policy, and safety.\nWhile small-scale studies of dehumanization and media representation of marginalized communities provide valuable insights (e.g. BIBREF10), there exist no known large-scale analyses, likely due to difficulties in quantifying such a subjective and multidimensional psychological process. However, the ability to do large-scale analysis is crucial for understanding how dehumanizing attitudes have evolved over long periods of time. Furthermore, by being able to account for a greater amount of media discourse at once, large-scale techniques can provide a more complete view of the media environment to which the public is exposed.\nLinguistics and computer science offer valuable methods and insights on which such large-scale techniques might be developed for the study of dehumanization. By leveraging more information about the contexts in which marginalized groups are discussed, computational linguistic methods not only enable large-scale study of a complex psychological phenomenon, but can even reveal linguistic variations and changes that are not easily identifiable through qualitative analysis alone.\nIn this work, we develop a computational linguistic framework for analyzing dehumanizing language, with a focus on lexical signals of dehumanization. Social psychologists have identified numerous components of dehumanization, such as negative evaluations of a target group, denial of agency, moral disgust, and likening members of a target group to non-human entities such as vermin. Drawing upon this rich body of literature, we first identify clear linguistic analogs for these components and propose several computational techniques to measure these linguistic correlates. We then apply this general framework to explore changing representations of LGBTQ groups in the New York Times over the span of three decades. We additionally use this lens of dehumanization to investigate differences in social meaning between the denotationally-similar labels gay and homosexual.\nThis paper aims to bridge the gaps between computational modeling, sociolinguistics, and dehumanization research with implications for several disciplines. In addition to enabling large-scale studies of dehumanizing language and media representation of marginalized social groups, these techniques can be built into systems that seek to capture both conscious and unconscious biases in text. Furthermore, this work has implications for improving machines' abilities to automatically detect hate speech and abusive language online, which are typically underpinned by dehumanizing language. Finally, our case study demonstrates that such computational analyses of discussions about marginalized groups can provide unique insights into language variation and change within sensitive sociopolitical contexts, and help us understand how people (and institutions) use language to express their ideologies and attitudes towards certain social groups.\nWe additionally use this lens of dehumanization to investigate differences in social meaning between the denotationally-similar labels gay and homosexual.",

        "evidence": "Adversarial examples are generally minimal perturbations applied to the input data in an effort to expose the regions of the input space where a trained model performs poorly. Prior works BIBREF0, BIBREF1 have demonstrated the ability of an adversary to evade state-of-the-art classifiers by carefully crafting attack examples which can be even imperceptible to humans. Following such approaches, there has been a number of techniques aimed at generating adversarial examples BIBREF2, BIBREF3. Depending on the degree of access to the target model, an adversary may operate in one of the two different settings: (a) black-box setting, where an adversary doesn't have access to target model's internal architecture or its parameters, (b) white-box setting, where an adversary has access to the target model, its parameters, and input feature representations. In both these settings, the adversary cannot alter the training data or the target model itself. Depending on the purpose of the adversary, adversarial attacks can be categorized as (a) targeted attack and (b) non-targeted attack. In a targeted attack, the output category of a generated example is intentionally controlled to a specific target category with limited change in semantic information. While a non-targeted attack doesn't care about the category of misclassified results.\nMost of the prior work has focused on image classification models where adversarial examples are obtained by introducing imperceptible changes to pixel values through optimization techniques BIBREF4, BIBREF5. However, generating natural language adversarial examples can be challenging mainly due to the discrete nature of text samples. Continuous data like image or speech is much more tolerant to perturbations compared to text BIBREF6. In textual domain, even a small perturbation is clearly perceptible and can completely change the semantics of the text. Another challenge for generating adversarial examples relates to identifying salient areas of the text where a perturbation can be applied successfully to fool the target classifier. In addition to fooling the target classifier, the adversary is designed with different constraints depending on the task and its motivations BIBREF7. In our work, we focus on constraining our adversary to craft examples with semantic preservation and minimum perturbations to the input text.\nGiven different settings of the adversary, there are other works that have designed attacks in “gray-box” settings BIBREF8, BIBREF9, BIBREF10. However, the definitions of “gray-box” attacks are quite different in each of these approaches. In this paper, we focus on “black-box” setting where we assume that the adversary possesses a limited set of labeled data, which is different from the target's training data, and also has an oracle access to the system, i.e., one can query the target classifier with any input and get its corresponding predictions. We propose an effective technique to generate adversarial examples in a black-box setting. We develop an Adversarial Example Generator (AEG) model that uses a reinforcement learning framing to generate adversarial examples. We evaluate our models using a word-based BIBREF11 and character-based BIBREF12 text classification model on benchmark classification tasks: sentiment classification and news categorization. The adversarial sequences generated are able to effectively fool the classifiers without changing the semantics of the text. Our contributions are as follows:\nWe propose a black-box non-targeted attack strategy by combining ideas of substitute network and adversarial example generation. We formulate it as a reinforcement learning task.\nWe introduce an encoder-decoder that operates over words and characters of an input text and empowers the model to introduce word and character-level perturbations.\nWe adopt a self-critical sequence training technique to train our model to generate examples that can fool or increase the probability of misclassification in text classifiers.\nWe evaluate our models on two different datasets associated with two different tasks: IMDB sentiment classification and AG's news categorization task. We run ablation studies on various components of the model and provide insights into decisions of our model.\nWe introduce an encoder-decoder that operates over words and characters of an input text and empowers the model to introduce word and character-level perturbations.",

Reverse perplexity (PPL-R) switches the roles of generated data and real data to reflect the discrepancy between the generated distribution and the data distribution. Self-BLEU (S-BLEU) regards each sentence in the generated collection as hypothesis and the others as reference to obtain BLEU scores, which evaluates the diversity of generated results.\nResults are shown in Table TABREF33 . LeakGAN performs best on forward perplexity because it can generate more fluent samples. As for reverse perplexity, our model ARAML beats other baselines, showing that our model can fit the data distribution better. Other GANs, particularly LeakGAN, obtain high reverse perplexity due to mode collapse BIBREF12 , thus they only capture limited fluent expressions, resulting in large discrepancy between the generated distribution and data distribution.

        "answer": "Precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nOn this material, we show that the ‘translated semantic fingerprints’method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments.",

        "evidence": "In this subsection, we discuss our main experimental results. As we observe that the results are heavily influenced by hyper-parameter tuning strategy, our main goal throughout our experiments is the validation of the proposed sample probing idea by integrating it into strong generative GZSL baselines, and then comparing results using the same tuning methodology. Using this principle, we present two main types of analysis: (i) the evaluation of the proposed approach using ESZSL as the probe model in combination with a number of generative GZSL models, and (ii) the evaluation of alternative closed-form probe models within our framework.\nGenerative GZSL models with sample probing. To evaluate the sample probing approach as a general technique to improve generative model training, we integrate it to four recent generative GZSL approaches: conditional Wasserstein GAN (cWGAN), LisGAN, TF-VAEGAN and FREE. We additionally report results for the variant of TF-VAEGAN with the fine-tuned representations (TF-VAEGAN-FT), as it is the only one among them with reported fine-tuning results.\nFor the cWGAN, we follow the implementation details described in Sariyildiz & Cinbis (2019), and tune hyper-parameters using our policy. For LisGAN, TF-VAEGAN and FREE models, we use the official repositories shared by their respective authors. We use the version of TF-VAEGAN without feedback loop, for simplicity, as the model yields excellent performance with and without feedback loop. In all models (except cWGAN), we only re-tune the number of training iterations of the original models using our hyper-parameter tuning policy, to make the re-Table: Evaluation of sample probing with multiple generative GZSL models on four benchmark datasets. Each row pair shows the effect of adding sample probing to a particular generative GZSL model, using ESZSL as the closed-form probe model. We use the same hyper-parameter optimization policy in all cases to make results comparable. sults comparable, as it is unclear how the original values were obtained. We keep all remaining hyper-parameters unchanged to remain as close as possible to the original implementations.\nThe results over the four benchmark datasets are presented in Table. In terms of the h-scores, we observe improvements in 17 out of 19 cases, at varying degrees (up to 4.6 points ). Only in two cases we observe a slight degradation (maximum of 0.2 points) in performance. Overall, these improvements over already strong and state-of-the-art (or competitive) baselines validate the effectiveness of the proposed sample probing approach, suggesting that it is a valid method towards end-to-end learning of generative GZSL models directly optimized for synthetic train data generation purposes.\nSample probing with alternative closed-form models. We now evaluate our approach with different closed-form probe models, specifically ESZSL, Sem2Vis and Vis2Sem, as described in Section 3.3. For these experiments, we use the TF-VAEGAN as the base generative model.\nThe results with four configurations over four benchmark datasets are presented in Table. First of all, in terms of h-scores, we observe considerable performance variations across the probe models and datasets: Sem2Vis performs the best on CUB (+0.9 over the baseline), ESZSL provides a clear gain on FLO (+4.6) and a relative improvement on AWA (+0.3), and Vis2Sem improves the most on SUN (+1.8). These results suggest that sample probe alternatives have their own advantages and disadvantages, and their performances can be data dependent. Therefore, in a practical application, probe model options can be incorporated into the model selection process. More in-depth understanding of closed-form model characteristics for sample probing purposes, and the formulation and evaluation of other probe models can be important future work directions. Overall, the fact that we observe equivalent (2) or better (9) h-scores in 11 out of 12 sample probing experiments indicates the versatility of the approach in terms of compatibility with various closed-form probe models.\nComparison to other generative GZSL approaches. Performance comparisons across independent experiment results can be misleading due to differences in formulation-agnostic implementation and model selection details. Nevertheless, an overall comparison can be found in Appendix A. and probe-validation classes, respectively. We observe that using either one during the evaluation of the sample probing ZSL model, brings its own characteristic results (Table). On all datasets, using zsl-loss increases the seen accuracy while using gzsl-loss increases the unseen accuracy. We choose among these two options using our same hyper-parameter tuning policy, on the validation set. Effect of sample probing loss weight. Figure shows the validation and test set h-score values as a function of sample probing loss weight. In the test set results, we observe an overall increasing performance trend with larger loss weights, up to the weight 6, highlighting the contribution of sample probing. The optimal weight with respect to the validation and the test sets, however, differs. This observation is an example for the difficulty of tuning the ZSL model based on validation set. We set the loss weight to 5 following our hyper-parameter tuning policy, which yields almost 0.5 lower than the maximum test-set score observed for this single hyper-parameter.\nQuantitative analysis of sample quality. We quantitatively evaluate the sample quality using Fréchet (Wasserstein-2) distance, which is also used in the FID metric for evaluating GAN models. In Table, we provide a comparison for TF-VAEGAN and our approach for respective mean per-class Fréchet distances between real and synthetic samples (200 synthetic samples per class) of unseen classes on three datasets. The results show that sample probing helps generator to generate more realistic samples compared to TF-VAEGAN. We further investigate the qualitative analysis of the sample quality via t-SNE visualizations in Appendix B.\nTable 1: Evaluation of sample probing with multiple generative GZSL models on four bench_x0002_mark datasets. Each row pair shows the effect of adding sample probing to a particular generative GZSL model, using ESZSL as the closed-form probe model.

        "evidence": "All the present neural LID methods are based on acoustic features, e.g., Mel filter banks (Fbanks) or Mel frequency cepstral coefficients (MFCCs), with phonetic information largely overlooked. This may have significantly hindered the performance of neural LID. Intuitively, it is a long-standing hypothesis that languages can be discriminated between by phonetic properties, either distributional or temporal; additionally, phonetic features represent information at a higher level than acoustic features, and so are more invariant with respect to noise and channels. Pragmatically, it has been demonstrated that phonetic information, either in the form of phone sequences, phone posteriors, or phonetic bottleneck features, can significantly improve LID accuracy in both the conventional PRLM approach BIBREF11 and the more modern i-vector system BIBREF34 , BIBREF35 , BIBREF36 . In this paper, we will investigate the utilization of phonetic information to improve neural LID. The basic concept is to use a phone-discriminative model to produce frame-level phonetic features, and then use these features to enhance RNN LID systems that were originally built with raw acoustic features. The initial step is therefore feature combination, with the phonetic feature used as auxiliary information to assist acoustic RNN LID. This is improved further, as additional research identified that a simpler model using only the phonetic feature as the RNN LID input provides even better performance. We call this RNN model based on phonetic features the phonetic temporal neural LID approach, or PTN LID. As well as having a simplified model structure, the PTN offers deeper insight into the LID task by rediscovering the value of the phonetic temporal property in language discrimination. This property was historically widely and successfully applied in token-based approaches, e.g., PRLM BIBREF11 , but has been largely overlooked due to the popularity of the i-vector approach.\nThe basic concept is to use a phone-discriminative model to produce frame-level phonetic features, and then use these features to enhance RNN LID systems that were originally built with raw acoustic features.

        "evidence": "In Turkish, there do not exist well-established sentiment lexicons as in English. In this approach, we made use of the TDK (Türk Dil Kurumu - “Turkish Language Institution”) dictionary to obtain word polarities. Although it is not a sentiment lexicon, combining it with domain-specific polarity scores obtained from the corpus led us to have state-of-the-art results.\nWe first construct a matrix whose row entries are corpus words and column entries are the words in their dictionary definitions. We followed the boolean approach. For instance, for the word cat, the column words occurring in its dictionary definition are given a score of 1. Those column words not appearing in the definition of cat are assigned a score of 0 for that corresponding row entry.\nWhen we performed clustering on this matrix, we observed that those words having similar meanings are, in general, assigned to the same clusters. However, this similarity fails in capturing the sentimental characteristics. For instance, the words happy and unhappy are assigned to the same cluster, since they have the same words, such as feeling, in their dictionary definitions. However, they are of opposite polarities and should be discerned from each other.\nTherefore, we utilise a metric to move such words away from each other in the VSM, even though they have common words in their dictionary definitions. We multiply each value in a row with the corresponding row word's raw supervised score, thereby having more meaningful clusters. Using the training data only, the supervised polarity score per word is calculated as in (DISPLAY_FORM4).\nHere, $ w_{t}$ denotes the sentiment score of word $t$, $N_{t}$ is the number of documents (reviews or tweets) in which $t$ occurs in the dataset of positive polarity, $N$ is the number of all the words in the corpus of positive polarity. $N^{\\prime }$ denotes the corpus of negative polarity. $N^{\\prime }_{t}$ and $N^{\\prime }$ denote similar values for the negative polarity corpus. We perform normalisation to prevent the imbalance problem and add a small number to both numerator and denominator for smoothing.\nAs an alternative to multiplying with the supervised polarity scores, we also separately multiplied all the row scores with only +1 if the row word is a positive word, and with -1 if it is a negative word. We have observed it boosts the performance more compared to using raw scores.\nThe effect of this multiplication is exemplified in Figure FIGREF7, showing the positions of word vectors in the VSM. Those “x\" words are sentimentally negative words, those “o\" words are sentimentally positive ones. On the top coordinate plane, the words of opposite polarities are found to be close to each other, since they have common words in their dictionary definitions. Only the information concerned with the dictionary definitions are used there, discarding the polarity scores. However, when we utilise the supervised score (+1 or -1), words of opposite polarities (e.g. “happy\" and “unhappy\") get far away from each other as they are translated across coordinate regions. Positive words now appear in quadrant 1, whereas negative words appear in quadrant 3. Thus, in the VSM, words that are sentimentally similar to each other could be clustered more accurately. Besides clustering, we also employed the SVD method to perform dimensionality reduction on the unsupervised dictionary algorithm and used the newly generated matrix by combining it with other subapproaches. The number of dimensions is chosen as 200 again according to the $U$ matrix. The details are given in Section 3.4. When using and evaluating this subapproach on the English corpora, we used the SentiWordNet lexicon BIBREF13. We have achieved better results for the dictionary-based algorithm when we employed the SVD reduction method compared to the use of clustering.\nIn Turkish, there do not exist well-established sentiment lexicons as in English.

Pointer+Coverage BIBREF9 , Abstract-ML+RL BIBREF10 and DCA BIBREF42 are all sequence to sequence learning based models with copy and coverage modeling, reinforcement learning and deep communicating agents extensions. SentRewrite BIBREF26 and InconsisLoss BIBREF25 all try to decompose the word by word summary generation into sentence selection from document and “sentence” level summarization (or compression). Bottom-Up BIBREF27 generates summaries by combines a word prediction model with the decoder attention model. The extractive models are usually based on hierarchical encoders (SummaRuNNer; BIBREF3 and NeuSum; BIBREF11 ). They have been extended with reinforcement learning (Refresh; BIBREF4 and BanditSum; BIBREF20 ), Maximal Marginal Relevance (NeuSum-MMR; BIBREF21 ), latent variable modeling (LatentSum; BIBREF5 ) and syntactic compression (JECS; BIBREF38 ). Lead3 is a baseline which simply selects the first three sentences. Our model $\\text{\\sc Hibert}_S$ (in-domain), which only use one pre-training stage on the in-domain CNNDM training set, outperforms all of them and differences between them are all significant with a 0.95 confidence interval (estimated with the ROUGE script).

He spots at the waxworks a romantic young couple, Georges (Russell Gleason), a lawyer, and Helene (Marguerite Churchill), the daughter of a stern judge (Lester Lonergan) who disapproves of his daughter's choice and forbids her to see Georges. Papa Chibou suggests to them that they can still stay in touch, without disobeying her father's directive not to speak with each other, by placing secret personal messages in the pockets of Napoleon's uniform.

        "evidence": "The BLEU scores in Table TABREF30 show a moderate improvement for most context-aware systems. This suggests that the architectural changes for the context-aware models do not degrade overall translation quality. The contrastive evaluation on our test set on the other hand shows a clear increase in the accuracy of pronoun translation: The best model s-hier-to-2.tied achieves a total of +16 percentage points accuracy on the test set over the baseline, see Table TABREF31 .\nTable TABREF32 shows that context-aware models perform better than the baseline when the antecedent is outside the current sentence. In our experiments, all context-aware models consider one preceding sentence as context. The evaluation according to the distance of the antecedent in Table TABREF35 confirms that the subset of sentences with antecedent distance 1 benefits most from the tested context-aware models (up to +20 percentage points accuracy). However, we note two surprising patterns:\nThe first observation can be explained by the distribution of German pronouns in the test set. The further away the antecedent, the higher the percentage of it INLINEFORM0 es cases, which are the majority class, and thus the class that will be predicted most often if evidence for other classes is lacking. We speculate that this is due to our more permissive extraction heuristics for it INLINEFORM1 es.\nWe attribute the second observation to the existence of coreference chains where the preceding sentence contains a pronoun that refers to the same nominal antecedent as the pronoun in the current sentence. Consider the example in Table TABREF36 : The nominal antecedent of it in the current sentence is door, Tür in German with feminine gender. The nominal antecedent occurs two sentences before the current sentence, but the German sentence in between contains the pronoun sie, which is a useful signal for the context-aware models, even though they cannot know the nominal antecedent.\nNote that only models aware of target-side context can benefit from such circumstances: The s-hier models as well as the Transformer model by BIBREF8 only see source side context, which results in lower accuracy if the distance to the antecedent is INLINEFORM0 1, see Table TABREF35 .\nWhile such coreference chains complicate the interpretation of the results, we note that improvements on inter-sentential anaphora with antecedent distance INLINEFORM0 are relatively small (compared to distance 1), and that performance is still relatively poor (especially for the minority classes er and sie). We encourage evaluation of wider-context models on this subset, which is still large thanks to the size of the full test set.\nRegarding the comparison of different context-aware architectures, our results demonstrate the effectiveness of parameter sharing between the main encoder (or decoder) and the contextual encoder. We observe an improvement of 5 percentage points from s-hier-to-2 to s-hier-to-2.tied, and 4 percentage points from s-t-hier to s-t-hier.tied. Context encoders introduce a large number of extra parameters, while inter-sentential context is only relevant for a relatively small number of predictions. We hypothesize that the training signal is thus too weak to train a strong contextual encoder in an end-to-end fashion without parameter sharing. Our results also confirm the finding by BIBREF9 that multi-encoder architectures, specifically s-hier-to-2(.tied), can outperform a simple concatenation system in the translation of coreferential pronouns.\nThe Transformer-based models perform strongest on pronouns with intra-segmental antecedent, outperforming the recurrent baseline by 9–18 percentage points. This is likely an effect of increased model depth and the self-attentional architecture in this set of experiments. The model by BIBREF8 only uses source context, and outperforms the most comparable RNN system, s-hier.tied. However, the Transformer-based concat22 slightly underperforms the RNN-based concat22, and we consider it future research how to better exploit target context with Transformer-based models.\nTable 7 shows that context-aware models perform better than the baseline when the antecedent is outside the current sentence.

        "answer": "Yes, it can.",
        "evidence": "Ethical considerations are established as essential part in planning mental health research and most research projects undergo approval by an ethics committee. On the contrary, the computational linguistics community has started only recently to consider ethical questions BIBREF72 , BIBREF73 . Likely, this is because computational linguistics was traditionally concerned with publicly available, impersonal texts such as newspapers or texts published with some temporal distance, which left a distance between the text and author. Conversely, recent social media research often deals with highly personal information of living individuals, who can be directly affected by the outcomes BIBREF72 .\n BIBREF72 discuss issues that can arise when constructing datasets from social media and conducting analyses or developing predictive models based on these data, which we review here in relation to our project: Demographic bias in sampling the data can lead to exclusion of minority groups, resulting in overgeneralisation of models based on these data. As discussed in the introduction, personal recovery research suffers from a bias towards English-speaking Western individuals of white ethnicity. By studying multilingual accounts of ethnically diverse populations we explicitly address the demographic bias of previous research. Topic overexposure is tricky to address, where certain groups are perceived as abnormal when research repeatedly finds that their language is different or more difficult to process. Unlike previous research BIBREF45 , BIBREF47 , BIBREF46 our goal is not to reveal particularities in the language of individuals affected by mental health problems. Instead, we will compare accounts of individuals with BD from different settings (structured interviews versus informal online discourse) and of different backgrounds. While the latter bears the risk to overexpose certain minority groups, we will pay special attention to this in the dissemination of our results.\nLastly, most research, even when conducted with the best intentions, suffers from the dual-use problem BIBREF74 , in that it can be misused or have consequences that affect people's life negatively. For this reason, we refrain from publishing mental health classification methods, which could be used, for example, by health insurance companies for the risk assessment of applicants based on their social media profiles.\nIf and how informed consent needs to be obtained for research on social media data is a debated issue BIBREF75 , BIBREF76 , BIBREF77 , mainly because it is not straightforward to determine if posts are made in a public or private context. From a legal point of view, the privacy policies of Twitter and Reddit, explicitly allow analysis of the user contents by third party, but it is unclear to what extent users are aware of this when posting to these platforms BIBREF78 . However, in practice it is often infeasible to seek retrospective consent from hundreds or thousands of social media users. According to current ethical guidelines for social media research BIBREF79 , BIBREF80 and practice in comparable research projects BIBREF81 , BIBREF78 , it is regarded as acceptable to waive explicit consent if the anonymity of the users is preserved. Therefore, we will not ask the account holders of Twitter and Reddit posts included in our datasets for their consent.\n BIBREF79 formulate guidelines for ethical social media health research that pertain especially to data collection and sharing. In line with these, we will only share anonymised and paraphrased excerpts from the texts, as it is often possible to recover a user name via a web search for the verbatim text of a post. However, we will make the original texts available as datasets to subsequent research under a data usage agreement. Since the (automatic) annotation of demographic variables in parts of our dataset constitutes especially sensitive information on minority status in conjunction with mental health, we will only share these annotations with researchers that demonstrate a genuine need for them, i.e. to verify our results or to investigate certain research questions.\nAnother important question is in which situations of encountering content indicative of a risk of self-harm or harm to others it would be appropriate or even required by duty of care for the research team to pass on information to authorities. Surprisingly, we could only find two mentions of this issue in social media research BIBREF81 , BIBREF82 . Acknowledging that suicidal ideation fluctuates BIBREF83 , we accord with the ethical review board's requirement in BIBREF81 to only analyse content posted at least three months ago. If the research team, which includes clinical psychologists, still perceives users at risk we will make use of the reporting facilities of Twitter and Reddit.\nAs a central component we consider the involvement of individuals with lived experience in our project, an aspect which is missing in the discussion of ethical social media health research so far. The proposal has been presented to an advisory board of individuals with a BD diagnosis and was received positively. The advisory board will be consulted at several stages of the project to inform the research design, analysis, and publication of results. We believe that board members can help to address several of the raised ethical problems, e.g., shaping the research questions to avoid feeding into existing biases or overexposing certain groups and highlighting potentially harmful interpretations and uses of our results.\nHovy and Spruit (2016) discuss issues that can arise when constructing datasets from social media and conducting analyses or developing predictive models based on these data, which we review here in relation to our project: Demographic bias in sampling the data can lead to exclusion of minority groups, resulting in overgeneralisation of models based on these data.",

        "answer": "Conversational Recurrent Architecture for ForecasTing.",
        "evidence": "We now describe our general model for forecasting future conversational events. Our model integrates two components: (a) a generative dialog model that learns to represent conversational dynamics in an unsupervised fashion; and (b) a supervised component that fine-tunes this representation to forecast future events. Figure FIGREF13 provides an overview of the proposed architecture, henceforth CRAFT (Conversational Recurrent Architecture for ForecasTing).\nTerminology. For modeling purposes, we treat a conversation as a sequence of $N$ comments $C = \\lbrace c_1,\\dots ,c_N\\rbrace $. Each comment, in turn, is a sequence of tokens, where the number of tokens may vary from comment to comment. For the $n$-th comment ($1 \\le n \\le N)$, we let $M_n$ denote the number of tokens. Then, a comment $c_n$ can be represented as a sequence of $M_n$ tokens: $c_n = \\lbrace w_1,\\dots ,w_{M_n}\\rbrace $.\nGenerative component. For the generative component of our model, we use a hierarchical recurrent encoder-decoder (HRED) architecture BIBREF60, a modified version of the popular sequence-to-sequence (seq2seq) architecture BIBREF61 designed to account for dependencies between consecutive inputs. BIBREF23 showed that HRED can successfully model conversational context by encoding the temporal structure of previously seen comments, making it an ideal fit for our use case. Here, we provide a high-level summary of the HRED architecture, deferring deeper technical discussion to BIBREF60 and BIBREF23.\nAn HRED dialog model consists of three components: an utterance encoder, a context encoder, and a decoder. The utterance encoder is responsible for generating semantic vector representations of comments. It consists of a recurrent neural network (RNN) that reads a comment token-by-token, and on each token $w_m$ updates a hidden state $h^{\\text{enc}}$ based on the current token and the previous hidden state:\nwhere $f^{\\text{RNN}}$ is a nonlinear gating function (our implementation uses GRU BIBREF62). The final hidden state $h^{\\text{enc}}_M$ can be viewed as a vector encoding of the entire comment.\nRunning the encoder on each comment $c_n$ results in a sequence of $N$ vector encodings. A second encoder, the context encoder, is then run over this sequence:\nEach hidden state $h^{\\text{con}}_n$ can then be viewed as an encoding of the full conversational context up to and including the $n$-th comment. To generate a response to comment $n$, the context encoding $h^{\\text{con}}_n$ is used to initialize the hidden state $h^{\\text{dec}}_{0}$ of a decoder RNN. The decoder produces a response token by token using the following recurrence:\nwhere $f^{\\text{out}}$ is some function that outputs a probability distribution over words; we implement this using a simple feedforward layer. In our implementation, we further augment the decoder with attention BIBREF63, BIBREF64 over context encoder states to help capture long-term inter-comment dependencies. This generative component can be pre-trained using unlabeled conversational data.\nPrediction component. Given a pre-trained HRED dialog model, we aim to extend the model to predict from the conversational context whether the to-be-forecasted event will occur. Our predictor consists of a multilayer perceptron (MLP) with 3 fully-connected layers, leaky ReLU activations between layers, and sigmoid activation for output. For each comment $c_n$, the predictor takes as input the context encoding $h^{\\text{con}}_n$ and forwards it through the MLP layers, resulting in an output score that is interpreted as a probability $p_{\\text{event}}(c_{n+1})$ that the to-be-forecasted event will happen (e.g., that the conversation will derail).\nTraining the predictive component starts by initializing the weights of the encoders to the values learned in pre-training. The main training loop then works as follows: for each positive sample—i.e., a conversation containing an instance of the to-be-forecasted event (e.g., derailment) at comment $c_e$—we feed the context $c_1,\\dots ,c_{e-1}$ through the encoder and classifier, and compute cross-entropy loss between the classifier output and expected output of 1. Similarly, for each negative sample—i.e., a conversation where none of the comments exhibit the to-be-forecasted event and that ends with $c_N$—we feed the context $c_1,\\dots ,c_{N-1}$ through the model and compute loss against an expected output of 0.\nNote that the parameters of the generative component are not held fixed during this process; instead, backpropagation is allowed to go all the way through the encoder layers. This process, known as fine-tuning, reshapes the representation learned during pre-training to be more directly useful to prediction BIBREF55.\nWe implement the model and training code using PyTorch, and we are publicly releasing our implementation and the trained models together with the data as part of ConvoKit.\n\nFigure 2 provides an overview of the proposed architecture, henceforth CRAFT (Conversational Recurrent Architecture for ForecasTing).",

Here a small portion of the large parallel corpus for English-German is used as a simulation for the scenario where we do not have much parallel data: Translating texts in English to German. We perform language-specific coding in both source and target sides. By accommodating the German monolingual data as an additional input (German INLINEFORM0 German), which we called the mix-source approach, we could enrich the training data in a simple, natural way. Given this under-resourced situation, it could help our NMT obtain a better representation of the source side, hence, able to learn the translation relationship better. Including monolingual data in this way might also improve the translation of some rare word types such as named entities. Furthermore, as the ultimate goal of our work, we would like to investigate the advantages of multilinguality in NMT. We incorporate a similar portion of French-German parallel corpus into the English-German one. As discussed in Section SECREF5 , it is expected to help reducing the ambiguity in translation between one language pair since it utilizes the semantic context provided by the other source language. We name this mix-multi-source.\nTable TABREF16 summarizes the performance of our systems measured in BLEU on two test sets, tst2013 and tst2014. Compared to the baseline NMT system which is solely trained on TED English-German data, our mix-source system achieves a considerable improvement of 2.6 BLEU points on tst2013 and 2.1 BLEU points on and tst2014 . Adding French data to the source side and their corresponding German data to the target side in our mix-multi-source system also help to gain 2.2 and 1.6 BLEU points more on tst2013 tst2014, respectively. We observe a better improvement from our mix-source system compared to our mix-multi-source system. We speculate the reason that the mix-source encoder utilize the same information shared in two languages while the mix-multi-source receives and processes similar information in the other language but not necessarily the same. We might validate this hypothesis by comparing two systems trained on a common English-German-French corpus of TED. We put it in our future work's plan.\nAs we expected Figure FIGREF19 shows how different words in different languages can be close in the shared space after being learned to translate into a common language.

Hive was deemed too slow for Facebook's scale and Presto was invented to fill the gap to run fast queries. Original development started in 2012 and deployed at Facebook later that year. In November 2013, Facebook announced its open source release.\n\nIn 2014, Netflix disclosed they used Presto on 10 petabytes of data stored in the Amazon Simple Storage Service (S3).

Off the wind, or heading away from the wind, the sails can be eased out to maintain this angle.  Heading into the wind, the boat can only get so close to the direction to keep the sails from becoming ineffective or \"luffing.\"  So to head in the general direction of the wind, a boat must tack at angles to the wind, to make its way in the direction of the wind.",

        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nOn the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook.",

        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones.",

        "answer": "SMT is short for the field of Statistical Machine Translation.",
        "evidence": "The use of RNNs in the field of Statistical Machine Translation (SMT) has revolutionised the approaches to automated translation. As opposed to traditional shallow SMT models, which require a lot of memory to run, these neural translation models require only a small fraction of memory used, about 5% BIBREF0 . Also, neural translation models are optimized such that every module is trained to jointly improve translation quality. With that being said, one of the main downsides of neural translation models is the heavy corpus requirement in order to ensure learning of deeper contexts. This is where the application of these encoder decoder architectures in translation to and/or from morphologically rich languages takes a severe hit.\nFor any language pair, the efficiency of an MT system depends on two major factors: the availability and size of parallel corpus used for training and the syntactic divergence between the two languages i.e morphological richness, word order differences, grammatical structure etc. BIBREF0 . The main differences between the languages stem from the fact that languages similar to English are predominantly fusional languages whereas many of the morphologically rich languages are agglutinative in nature. The nature of morphologically rich languages being structurally and semantically discordant from languages like English adds to the difficulty of SMT involving such languages.\nIn morphologically rich languages, any suffix can be added to any verb or noun to simply mean one specific thing about that particular word that the suffix commonly represents (agglutination). This means that there exists a lot of inflectional forms of the same noun and verb base words, conveying similar notions. For example, in Tamil, there are at least 30,000 inflectional forms of any given verb and about 5,000 forms of inflectional forms for any noun. The merged words carry information about part of speech (POS) tags, tense, plurality and so forth that are important for analyzing text for Machine Translation (MT). Not only are these hidden meanings not captured, the corresponding root words are trained as different units, thereby increasing the complexity of developing such MT systems BIBREF1 .\nTo add to the complexities of being a morphologically rich language, there are several factors unique to Tamil that make translation very difficult. The availability of parallel corpus for Tamil is very scarce. Most of the other models in the field of English–Tamil MT have made use of their own translation corpora that were manually created for the purposes of research. Most of these corpora are not available online for use.\nAnother issue specific to Tamil is the addition of suffix characters included to the words in the language for smoothness in pronunciation. These characters are of so many different types; there is a unique suffix for each and every consonant in the language. These suffixes degrade performance of MT because the same words with different such pronounciation-based suffixes will be taken as different words in training.\nAlso to take into consideration is the existence of two different forms of the language being used. Traditionally defined Tamil and its pronunciations aren't acoustically pleasing to use. There's no linguistic flow between syllables and its usage in verbal communication is time consuming. Therefore, there exists two forms of the language, the written form, rigid in structure and syntax, and the spoken form, in which the flow and pace of the language is given priority over syntax and correctness of spelling. This divide leads to the corpus having 2 different versions of the language that increase the vocabulary even with the same words. This can be evidently seen in the corpus between the sentences used in the Bible, which is in traditional Tamil and sentences from movie subtitles, being in spoken Tamil format.\nTo account for such difficulties, a trade-off between domain specificity and size of the corpus is integral in building an English–Tamil neural MT system.\nThe use of RNNs in the field of Statistical Machine Translation (SMT) has revolutionised the approaches to automated translation.",

Several NLP problems can be formulated in this way, such as patent, news articles, books and movie genres classification (as well as many other classification tasks like diseases, gene function prediction). Also, many tasks can be formulated as hierarchical problem in order to cope with a large amount of labels to assign to the sample, in a divide and conquer manner (with pseudo meta-labels). A theoretical survey exists BIBREF0 discussing on how the task can be engaged, several approaches and the prediction quality measures. Basically, the task in HMC is to assign a sample to one or many nodes of a Directed Acyclic Graph (DAG) (in special cases a tree) based on features extracted from the sample. In the case of possible multiple parent, the evaluation of the prediction complicates heavily, for once since several paths can be taken, but only in a joining node must be considered.\nThe GermEval 2019 Task 1 - Shared Task on hierarchical classification of German blurbs focus on the concrete challenge of classifying short descriptive texts of books into the root nodes (subtask A) or into the entire hierarchy (subtask B). The hierarchy can be described as a tree and consisted of 343 nodes, in which there are 8 root nodes. With about 21k samples it was not clear if deep learning methods or traditional NLP methods would perform better. Especially, in the subtask A, since for subtask B some classes had only a few examples. Although an ensemble of traditional and deep learning methods could profit in this area, it is difficult to design good heterogeneous ensembles.\nOur approach was a traditional NLP one, since we employed them successfully in several projects BIBREF1, BIBREF2, BIBREF3, with even more samples and larger hierarchies. We compared also new libraries and our own implementation, but focused on the post-processing of the multi-labels, since this aspect seemed to be the most promising improvement to our matured toolkit for this task.

        "question": "Which aspect considered by authors is the missing in the discussion of ethical social media health research so far?",
        "answer": "The involvement of individuals with lived experience in their project.",
        "evidence": "Ethical considerations are established as essential part in planning mental health research and most research projects undergo approval by an ethics committee. On the contrary, the computational linguistics community has started only recently to consider ethical questions BIBREF72 , BIBREF73 . Likely, this is because computational linguistics was traditionally concerned with publicly available, impersonal texts such as newspapers or texts published with some temporal distance, which left a distance between the text and author. Conversely, recent social media research often deals with highly personal information of living individuals, who can be directly affected by the outcomes BIBREF72 .\n BIBREF72 discuss issues that can arise when constructing datasets from social media and conducting analyses or developing predictive models based on these data, which we review here in relation to our project: Demographic bias in sampling the data can lead to exclusion of minority groups, resulting in overgeneralisation of models based on these data. As discussed in the introduction, personal recovery research suffers from a bias towards English-speaking Western individuals of white ethnicity. By studying multilingual accounts of ethnically diverse populations we explicitly address the demographic bias of previous research. Topic overexposure is tricky to address, where certain groups are perceived as abnormal when research repeatedly finds that their language is different or more difficult to process. Unlike previous research BIBREF45 , BIBREF47 , BIBREF46 our goal is not to reveal particularities in the language of individuals affected by mental health problems. Instead, we will compare accounts of individuals with BD from different settings (structured interviews versus informal online discourse) and of different backgrounds. While the latter bears the risk to overexpose certain minority groups, we will pay special attention to this in the dissemination of our results.\nLastly, most research, even when conducted with the best intentions, suffers from the dual-use problem BIBREF74 , in that it can be misused or have consequences that affect people's life negatively. For this reason, we refrain from publishing mental health classification methods, which could be used, for example, by health insurance companies for the risk assessment of applicants based on their social media profiles.\nIf and how informed consent needs to be obtained for research on social media data is a debated issue BIBREF75 , BIBREF76 , BIBREF77 , mainly because it is not straightforward to determine if posts are made in a public or private context. From a legal point of view, the privacy policies of Twitter and Reddit, explicitly allow analysis of the user contents by third party, but it is unclear to what extent users are aware of this when posting to these platforms BIBREF78 . However, in practice it is often infeasible to seek retrospective consent from hundreds or thousands of social media users. According to current ethical guidelines for social media research BIBREF79 , BIBREF80 and practice in comparable research projects BIBREF81 , BIBREF78 , it is regarded as acceptable to waive explicit consent if the anonymity of the users is preserved. Therefore, we will not ask the account holders of Twitter and Reddit posts included in our datasets for their consent.\n BIBREF79 formulate guidelines for ethical social media health research that pertain especially to data collection and sharing. In line with these, we will only share anonymised and paraphrased excerpts from the texts, as it is often possible to recover a user name via a web search for the verbatim text of a post. However, we will make the original texts available as datasets to subsequent research under a data usage agreement. Since the (automatic) annotation of demographic variables in parts of our dataset constitutes especially sensitive information on minority status in conjunction with mental health, we will only share these annotations with researchers that demonstrate a genuine need for them, i.e. to verify our results or to investigate certain research questions.\nAnother important question is in which situations of encountering content indicative of a risk of self-harm or harm to others it would be appropriate or even required by duty of care for the research team to pass on information to authorities. Surprisingly, we could only find two mentions of this issue in social media research BIBREF81 , BIBREF82 . Acknowledging that suicidal ideation fluctuates BIBREF83 , we accord with the ethical review board's requirement in BIBREF81 to only analyse content posted at least three months ago. If the research team, which includes clinical psychologists, still perceives users at risk we will make use of the reporting facilities of Twitter and Reddit.\nAs a central component we consider the involvement of individuals with lived experience in our project, an aspect which is missing in the discussion of ethical social media health research so far. The proposal has been presented to an advisory board of individuals with a BD diagnosis and was received positively. The advisory board will be consulted at several stages of the project to inform the research design, analysis, and publication of results. We believe that board members can help to address several of the raised ethical problems, e.g., shaping the research questions to avoid feeding into existing biases or overexposing certain groups and highlighting potentially harmful interpretations and uses of our results.\nAs a central component we consider the involvement of individuals with lived experience in our project, an aspect which is missing in the discussion of ethical social media health research so far.",

        "question": "Is their study the first one to apply a deep learning model to the multilingual sentiment analysis task?",
        "answer": "Yes.",
        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nTo the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.",

        "question": "From the text provided, give me a summary of the most popular attractions in Yosemite National Park.",
        "evidence": "Yosemite Valley represents only one percent of the park area, but this is where most visitors arrive and stay. The Tunnel View is the first view of the Valley for many visitors and is extensively photographed. El Capitan, a prominent granite cliff that looms over Yosemite Valley, is one of the most popular rock climbing destinations in the world because of its diverse range of climbing routes in addition to its year-round accessibility. Granite domes such as Sentinel Dome and Half Dome rise 3,000 and 4,800 feet (910 and 1,460 m), respectively, above the valley floor. The park contains dozens of other granite domes.\n\nThe high country of Yosemite contains beautiful areas such as Tuolumne Meadows, Dana Meadows, the Clark Range, the Cathedral Range, and the Kuna Crest. The Sierra crest and the Pacific Crest Trail run through Yosemite, with peaks of red metamorphic rock, such as Mount Dana and Mount Gibbs, and granite peaks, such as Mount Conness. Mount Lyell is the highest point in the park, standing at 13,120 feet (4,000 m). The Lyell Glacier is the largest glacier in Yosemite National Park and is one of the few remaining in the Sierra Nevada.\n\nThe park has three groves of ancient giant sequoia (Sequoiadendron giganteum) trees; the Mariposa Grove (200 trees), the Tuolumne Grove (25 trees), and the Merced Grove (20 trees). This species grows larger in volume than any other and is one of the tallest and longest-lived.\n\nWater and ice\n\nThe Merced River flowing through Yosemite Valley, a U-shaped valley\nThe Tuolumne and Merced River systems originate along the crest of the Sierra Nevada in the park and have carved river canyons 3,000 to 4,000 feet (910 to 1,220 m) deep. The Tuolumne River drains the entire northern portion of the park, an area of approximately 680 square miles (1,800 km2). The Merced River begins in the park's southern peaks, primarily the Cathedral and Clark Ranges, and drains an area of approximately 511 square miles (1,320 km2).\n\nHydrologic processes, including glaciation, flooding, and fluvial geomorphic response, have been fundamental in creating landforms in the park. The park also contains approximately 3,200 lakes (greater than 100 m2), two reservoirs, and 1,700 miles (2,700 km) of streams, all of which help form these two large watersheds. Wetlands in Yosemite occur in valley bottoms throughout the park, and are often hydrologically linked to nearby lakes and rivers through seasonal flooding and groundwater movement. Meadow habitats, distributed at elevations from 3,000 to 11,000 feet (910 to 3,350 m) in the park, are generally wetlands, as are the riparian habitats found on the banks of Yosemite's numerous streams and rivers.\n\n\nBridalveil Fall flows from a U-shaped hanging valley that was created by a tributary glacier.\nYosemite is famous for its high concentration of waterfalls in a small area. Numerous sheer drops, glacial steps and hanging valleys in the park provide many places for waterfalls to exist, especially during April, May, and June (the snowmelt season). Located in Yosemite Valley, the Yosemite Falls is the highest in North America at 2,425 feet (739 m). Also in Yosemite Valley is the much lower volume Ribbon Falls, which has the highest single vertical drop, 1,612 feet (491 m). Perhaps the most prominent of the Yosemite Valley waterfalls is Bridalveil Fall, which is the waterfall seen from the Tunnel View viewpoint at the east end of the Wawona Tunnel. Wapama Falls in Hetch Hetchy Valley is another notable waterfall. Hundreds of ephemeral waterfalls can become active in the park after heavy rains or melting snowpack.\n\nAll glaciers in the park are relatively small glaciers that occupy areas that are in almost permanent shade, such as north- and northeast-facing cirques. Lyell Glacier is the largest glacier in Yosemite (the Palisades Glaciers are the largest in the Sierra Nevada) and covers 160 acres (65 ha). None of the Yosemite glaciers are a remnant of the Ice Age alpine glaciers responsible for sculpting the Yosemite landscape. Instead, they were formed during one of the neoglacial episodes that have occurred since the thawing of the Ice Age (such as the Little Ice Age). Many Yosemite glaciers, such as the Black Mountain Glacier that was discovered in 1871 and gone by the mid-1980s, have disappeared. Yosemite's final two glaciers – the Lyell and Maclure glaciers – have receded over the last 100 years and are expected by scientists to eventually disappear as a result of natural melting and climate change.",
        "answer": "Although Yosemite National Park is perhaps best known for attractions located in the seven square mile Yosemite Valley, the park is quite large and contains popular attractions ranging from groves of giant sequoias, to glaciers and waterfalls, to dozens of granite domes.

        "question": "What age should babies be potty trained?",
        "evidence": "",
        "answer": "When a baby is ready for potty training depends on several factors.  There is no universal answer or age that a child is ready to be potty trained.  However, some signs that a child is ready to be potty trained are signaling and/or awareness of when a child is or needs to eliminate waste.   Another factor is when the care taker has the time to dedicate to consistent practice of eliminating in a toilet instead of a diaper. Infant potty training also known as elimination communication is the practice of skipping the reliance of the usage of diapers.  In this practice, the caretaker will teach signs to the baby every time the baby eliminates in the toilet (not in a diaper) - the baby will eventually pick up these signs and give cues when they need to go.  Those that subscribe to infant potty training believe that conventional diapers train babies to ignore their natural instincts by removing the discomfort one would normally sense from having wet skin (achieved by chemicals that absorb liquid and wick moisture away from the skin found in many disposable diapers).  While infant potty training takes a lot of upfront attention and discipline, young children can be fully potty trained by 9-16 months of age.  On the other hand, potty training children that have been in diapers are usually potty trained by about 36 months of age.  There are considerable convenience trade offs to both methods.",

As shown in Figure 3 , medical model features, the bio-medical entities, have been extracted from the free text only, exploiting advanced NLP techniques and using domain dictionaries.\nIn details, we newly define and extract from the dataset the following novel features:\nThe idea of considering infoboxes is not novel: for example, in BIBREF7 the authors noticed that the presence of an infobox is a characteristic featured by good articles. However, in the specific case of the Medicine Portal, the presence of an infobox does not seem strictly related to the quality class the article belongs to (according to the manual labelling). Indeed, it is recurrent that articles, spanning all classes, have an infobox, containing a schematic synthesis of the article. In particular, pages with descriptions of diseases usually have an infobox with the medical standard code of the disease (i.e., IDC-9 and IDC-10), as in Figure 2 .\nAs done for the baseline, also the first two features of the medical model have been extracted with ad hoc Python scripts, extracting HTML structures and excerpts of the textual content within the MediaWiki tags. For their extraction of the bio-medical entities, we consider the textual part of the article only, obtained after removing the MediaWiki tags, and we apply a NLP analysis, which is presented in Section \"Bio-medical entities\" .\nHere, we improve the baseline model with novel and specifically crafted features that rely on the medical domain and that capture details on the specific content of an article.",

To this end, we used another English dataset from BIBREF8 . It consists of 25,000 sarcastic tweets and 75,000 non-sarcastic tweets.\nWe have obtained this dataset from The Sarcasm Detector. It contains 120,000 tweets, out of which 20,000 are sarcastic and 100,000 are non-sarcastic. We randomly sampled 10,000 sarcastic and 20,000 non-sarcastic tweets from the dataset. Visualization of both the original and subset data show similar characteristics.\nA two-step methodology has been employed in filtering the datasets used in our experiments. Firstly, we identified and removed all the “user\", “URL\" and “hashtag\" references present in the tweets using efficient regular expressions. Special emphasis was given to this step to avoid traces of hashtags, which might trigger the models to provide biased results. Secondly, we used NLTK Twitter Tokenizer to ensure proper tokenization of words along with special symbols and emoticons. Since our deep CNNs extract contextual information present in tweets, we include emoticons as part of the vocabulary. This enables the emoticons to hold a place in the word embedding space and aid in providing information about the emotions present in the sentence.\nIt is a monolingual English dataset which consists of a balanced distribution of 50,000 sarcastic tweets and 50,000 non-sarcastic tweets.",

        "evidence": "Princeton WordNet BIBREF0 is one of the most important resources used in many different tasks across linguistics and natural language processing, however the resource is only available for English and is limited in its coverage of real world concepts. To cross the language barrier, huge efforts have been made to extend the Princeton WordNet with multilingual information in projects, such as EuroWordNet BIBREF1 , BalkaNet BIBREF2 and MultiWordNet BIBREF3 , mostly following the extend approach, where the structure of the Princeton WordNet is preserved and only the words in each synset are translated and new synsets are added for concepts. Furthermore, the Princeton WordNet has many fewer concepts than large scale encyclopedias such as Wikipedia and resources derived from it such as DBpedia BIBREF4 and BabelNet BIBREF5 . This problem is even worse for many non-English wordnets, due to the extend approach, as these resources have even fewer synsets than Princeton WordNet. Furthermore, there are still many languages for which a wordnet does not exist or is not available to all potential users due to licensing restrictions.\nTo address these deficiencies we propose two approaches. Firstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages. While an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries. In addition, our method can handle fundamental complexities such as the need to translate all senses of a word including low-frequency senses, which is very challenging for current SMT approaches. For these reasons, we leverage existing translations of Princeton WordNet entries in other languages to identify contextual information for wordnet senses from a large set of generic parallel corpora. The goal is to identify sentences that share the same semantic information in respect to the synset of the Princeton WordNet entry that we want to translate. Secondly, we describe a novel system based on state-of-the-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia. This method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks. These statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph. These are combined using a constraint-based solver that considers not only the semantic similarity of the synsets but also the overall structure of the alignment and its consistency, following the best practices in ontology alignment.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet BIBREF6 , which is available under an open (CC-BY) license. Finally, we describe how this resource is published, firstly as linked data in the linguistic linked open data cloud, as well as published in all the formats of the Global WordNet Association Interlingual Index.\nThis method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks.",

        "evidence": "We tested the proposed UTCNN on two different datasets: FBFans and CreateDebate. FBFans is a privately-owned, single-topic, Chinese, unbalanced, social media dataset, and CreateDebate is a public, multiple-topic, English, balanced, forum dataset. Results using these two datasets show the applicability and superiority for different topics, languages, data distributions, and platforms.\nThe FBFans dataset contains data from anti-nuclear-power Chinese Facebook fan groups from September 2013 to August 2014, including posts and their author and liker IDs. There are a total of 2,496 authors, 505,137 likers, 33,686 commenters, and 505,412 unique users. Two annotators were asked to take into account only the post content to label the stance of the posts in the whole dataset as supportive, neutral, or unsupportive (hereafter denoted as Sup, Neu, and Uns). Sup/Uns posts were those in support of or against anti-reconstruction; Neu posts were those evincing a neutral standpoint on the topic, or were irrelevant. Raw agreement between annotators is 0.91, indicating high agreement. Specifically, Cohen’s Kappa for Neu and not Neu labeling is 0.58 (moderate), and for Sup or Uns labeling is 0.84 (almost perfect). Posts with inconsistent labels were filtered out, and the development and testing sets were randomly selected from what was left. Posts in the development and testing sets involved at least one user who appeared in the training set. The number of posts for each stance is shown on the left-hand side of Table TABREF12 . About twenty percent of the posts were labeled with a stance, and the number of supportive (Sup) posts was much larger than that of the unsupportive (Uns) ones: this is thus highly skewed data, which complicates stance classification. On average, 161.1 users were involved in one post. The maximum was 23,297 and the minimum was one (the author). For comments, on average there were 3 comments per post. The maximum was 1,092 and the minimum was zero.\nTo test whether the assumption of this paper – posts attract users who hold the same stance to like them – is reliable, we examine the likes from authors of different stances. Posts in FBFans dataset are used for this analysis. We calculate the like statistics of each distinct author from these 32,595 posts. As the numbers of authors in the Sup, Neu and Uns stances are largely imbalanced, these numbers are normalized by the number of users of each stance. Table TABREF13 shows the results. Posts with stances (i.e., not neutral) attract users of the same stance. Neutral posts also attract both supportive and neutral users, like what we observe in supportive posts, but just the neutral posts can attract even more neutral likers. These results do suggest that users prefer posts of the same stance, or at least posts of no obvious stance which might cause annoyance when reading, and hence support the user modeling in our approach.\nThe CreateDebate dataset was collected from an English online debate forum discussing four topics: abortion (ABO), gay rights (GAY), Obama (OBA), and marijuana (MAR). The posts are annotated as for (F) and against (A). Replies to posts in this dataset are also labeled with stance and hence use the same data format as posts. The labeling results are shown in the right-hand side of Table TABREF12 . We observe that the dataset is more balanced than the FBFans dataset. In addition, there are 977 unique users in the dataset. To compare with Hasan and Ng's work, we conducted five-fold cross-validation and present the annotation results as the average number of all folds BIBREF9 , BIBREF5 .\nThe FBFans dataset has more integrated functions than the CreateDebate dataset; thus our model can utilize all linguistic and extra-linguistic features. For the CreateDebate dataset, on the other hand, the like and comment features are not available (as there is a stance label for each reply, replies are evaluated as posts as other previous work) but we still implemented our model using the content, author, and topic information.\nWe tested the proposed UTCNN on two different datasets: FBFans and CreateDebate.",

To me, that assumption is an artifact for the proof techniques, which undermines the contributions of the paper.",
        "answer": "Sorry for the confusion. First, in practice, there are natural random variables that satisfy our assumption. For example, assume that we want to use machine A to measure the length of several objects and use machine B to measure their temperature. The measured lengths and temperatures follow i.i.d. Gaussian distribution. However, the variance of measurement of machine A is different from that of machine B. Then we consider the random vector formed by the measurements (length of object 1, length of object 2, ..., length of object n, temperature of object 1, temperature of object 2, ..., temperature of object n). This results in a block-structured covariance matrix. When we measure more objects, the size of the covariance matrix tends to infinity. Second, the motivation came from (Nakkiran et al., 2021). Nakkiran et al. (2021) observed  empirically in their Figure 2 that when the covariance matrix has a block structure (specifically, there are only two fixed different eigenvalues 10 and 1), the expected excess risk exhibits multiple descent. We quantitatively studied this observation and obtained the related formulae. We stated this in the third item in Section 1.2. We further clarified in the revision.",

This provides a theoretical proof of a phenomenon observed in (Nakkiran et al., 2021) that optimal regularization can mitigate double descent for anisotropic data. Note that without regularization, there will be a blow-up in expected excess risk when n = d (the linear model exactly interpolates the data) and therefore, there is no samplewise descent across the under- and over-parameterized regimes.",

However, a low resource language's writing system is likely to be similar to the writing systems of languages that do have sufficient pronunciation data. Therefore g2p may be possible for low resource languages if this high resource data can be properly utilized.\nWe attempt to leverage high resource data by treating g2p as a multisource neural machine translation (NMT) problem. The source sequences for our system are words in the standard orthography in any language. The target sequences are the corresponding representation in the International Phonetic Alphabet (IPA).

This is because every tendon has a stretch reflex, and when triggered, will cause the muscle connected to it to contract; for example, when the patellar tendon underneath your knee is hit by your doctor during your yearly checkup, your quads contract involuntarily and your leg kicks up. When you are stretching, you are elongating the muscles. If you bounce while stretching, you can activate your tendon’s stretch reflex, causing your muscle to try and contract while also elongating it, which may tear the muscle or even detach the tendon from the bone in extreme cases.

It covers the bulk of the Arabian Peninsula, and has a land area of about 2,150,000 km2 (830,000 sq mi), making it the fifth-largest country in Asia, the second-largest in the Arab world, and the largest in Western Asia and the Middle East. It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Qatar and the United Arab Emirates to the east; Oman to the southeast; and Yemen to the south. Bahrain is an island country off its east coast. The Gulf of Aqaba in the northwest separates Saudi Arabia from Egypt and Israel. Saudi Arabia is the only country with a coastline along both the Red Sea and the Persian Gulf, and most of its terrain consists of arid desert, lowland, steppe, and mountains. Its capital and largest city is Riyadh. The country is home to Mecca and Medina, the two holiest cities in Islam.\n\nPre-Islamic Arabia, the territory that constitutes modern-day Saudi Arabia, was the site of several ancient cultures and civilizations; the prehistory of Saudi Arabia shows some of the earliest traces of human activity in the world. The world's second-largest religion, Islam, emerged in what is now Saudi Arabia. In the early 7th century, the Islamic prophet Muhammad united the population of the Arabian Peninsula and created a single Islamic religious polity. Following his death in 632, his followers rapidly expanded the territory under Muslim rule beyond Arabia, conquering huge and unprecedented swathes of territory (from the Iberian Peninsula in the west to parts of Central and South Asia in the east) in a matter of decades. Arab dynasties originating from modern-day Saudi Arabia founded the Rashidun (632–661), Umayyad (661–750), Abbasid (750–1517), and Fatimid (909–1171) caliphates, as well as numerous other dynasties in Asia, Africa, and Europe.",

        "answer": "The strength of a business analyst is their domain knowledge and ability to understand business process, gather requirements from business users and perform analysis and preparing requirements artefacts (BRD, process flow, UAT Document). Most of this information is gathered by interacting with business users.  As a first step the business analyst like any other employee should familiarise themselves with the company way of working, introducing themselves and making connection with fellow team members and business users.the BA next needs to understand the business process of the systems and application he/she will be supporting. This would require speaking to the business users to understand the as-is process, going through existing BRD and process flow documents to understand as-is structure. Regular 1:1 with key business stakeholders does help. BA also needs to establish relationship with the IT team, after all its them who will be implementing the BRD BA documents. BA needs to understand the current IT system and overview of teh technologies the current issues/challenges the IT team faces.

        "evidence": "Hausa language is the second most spoken indigenous language in Africa with over 40 million native speakers BIBREF20, and one of the three major languages in Nigeria, along with Igbo and Yorùbá. The language is native to the Northern part of Nigeria and the southern part of Niger, and it is widely spoken in West and Central Africa as a trade language in eight other countries: Benin, Ghana, Cameroon, Togo, Côte d'Ivoire, Chad, Burkina Faso, and Sudan. Hausa has several dialects but the one regarded as standard Hausa is the Kananci spoken in the ancient city of Kano in Nigeria. Kananci is the dialect popularly used in many local (e.g VON news) and international news media such as BBC, VOA, DW and Radio France Internationale. Hausa is a tone language but the tones are often ignored in writings, the language is written in a modified Latin alphabet. Despite the popularity of Hausa as an important regional language in Africa and it's popularity in news media, it has very little or no labelled data for common NLP tasks such as text classification, named entity recognition and question answering.\nYorùbá language is the third most spoken indigenous language in Africa after Swahilli and Hausa with over 35 million native speakers BIBREF20. The language is native to the South-western part of Nigeria and the Southern part of Benin, and it is also spoken in other countries like Republic of Togo, Ghana, Côte d'Ivoire, Sierra Leone, Cuba and Brazil. Yorùbá has several dialects but the written language has been standardized by the 1974 Joint Consultative Committee on Education BIBREF21, it has 25 letters without the Latin characters (c, q, v, x and z) and with additional characters (ẹ, gb, ṣ , ọ). Yorùbá is a tone language and the tones are represented as diacritics in written text, there are three tones in Yorùbá namely low ( \\), mid (“$-$”) and high ($/$). The mid tone is usually ignored in writings. Often time articles written online including news articles like BBC and VON ignore diacritics. Ignoring diacritics makes it difficult to identify or pronounce words except they are in a context. For example, owó (money), ọw (broom), òwò (business), w (honour), ọw (hand), and w (group) will be mapped to owo without diacritics.

We always use the development sets of SQuAD, DRCD and KorQuAD for testing since the testing sets of the corpora have not been released yet.\nNext, to construct a diverse cross-lingual RC dataset with compromised quality, we translated the English and Chinese datasets into more languages, with Google Translate. An obvious issue with this method is that some examples might no longer have a recoverable span. To solve the problem, we use fuzzy matching to find the most possible answer, which calculates minimal edit distance between translated answer and all possible spans. If the minimal edit distance is larger than min(10, lengths of translated answer - 1), we drop the examples during training, and treat them as noise when testing. In this way, we can recover more than 95% of examples. The following generated datasets are recovered with same setting.\nThe pre-trained multi-BERT is the official released one. This multi-lingual version of BERT were pre-trained on corpus in 104 languages. Data in different languages were simply mixed in batches while pre-training, without additional effort to align between languages.

After attending Wimbledon High School in London, Blackman spent two years, from 1924, at a Kunstgewerbeschule in Graz in Austria before returning to England to study at Goldsmiths College School of Art until 1930 and then at the University of Reading from 1931 until 1935.\n\nBlackman initially worked in bronze to produce small group pieces and figures but after World War II began using terracotta and stoneware before concentrating on creating ceramic figures. In her ceramic work, Blackman worked rolled and slabbed pieces of clay into figurines and, in 1978, published a handbook, Rolled Pottery Figures, on her technique. Later in her life she produced more abstract pieces, including paintings in both watercolour and gouache.\n\nBlackman was a regular exhibitor with the Society of Women Artists, SWA, and at the Royal Academy in London. She showed some 48 works with the SWA between 1939 and 1971 and was elected an associate member in 1952 and a full member in 1961. Seventeen works by Blackman were included in Royal Academy exhibitions between 1938 and 1960. She also exhibited on at least one occasion at the Royal Glasgow Institute of the Fine Arts and was a member of the Art Workers Guild. Blackman was active in several bodies promoting arts and crafts including the International Academy of Ceramics, the Craft Advisory Committee and the Federation of British Craft Societies.\n\nLiving in Boar's Hill near Oxford, she married Geoffrey Blackman, the Sibthorpian professor of rural economy at Oxford University, and she was long associated with that University's St Cross College, where several examples of her sculpture and pottery are held and a room is named in her memory.",

He was the youngest person to assume the presidency by election and the youngest president at the end of his tenure. Kennedy served at the height of the Cold War, and the majority of his foreign policy concerned relations with the Soviet Union and Cuba. A Democrat, Kennedy represented Massachusetts in both houses of the U.S. Congress prior to his presidency.\n\nBorn into the prominent Kennedy family in Brookline, Massachusetts, Kennedy graduated from Harvard University in 1940 before joining the U.S. Naval Reserve the following year. During World War II, he commanded a series of PT boats in the Pacific theater. Kennedy's survival following the sinking of PT-109 and his rescue of his fellow sailors made him a war hero and earned the Navy and Marine Corps Medal, but left him with serious injuries. After a brief stint in journalism, Kennedy represented a working-class Boston district in the U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate and served as the junior senator for Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage, which won a Pulitzer Prize. Kennedy ran in the 1960 presidential election. His campaign gained momentum after the first televised presidential debates in American history, and he was elected president, narrowly defeating Republican opponent Richard Nixon, who was the incumbent vice president. He was the first Catholic elected president.\n\nKennedy's administration included high tensions with communist states in the Cold War. He increased the number of American military advisors in South Vietnam. He authorized numerous operations to overthrow the Cuban government of Fidel Castro, including the failed Bay of Pigs Invasion in April 1961. The following October, U.S. spy planes discovered Soviet missile bases in Cuba; the resulting period of tensions, termed the Cuban Missile Crisis, nearly resulted in the breakout of a global thermonuclear conflict. He also signed the first nuclear weapons treaty in October 1963. Kennedy presided over the establishment of the Peace Corps, Alliance for Progress with Latin America, and the continuation of the Apollo program with the goal of landing a man on the Moon. He also supported the civil rights movement but was only somewhat successful in passing his New Frontier domestic policies.\n\nOn November 22, 1963, Kennedy was assassinated in Dallas. His vice president, Lyndon B. Johnson, assumed the presidency upon Kennedy's death. Lee Harvey Oswald, a former U.S. Marine, was arrested for the assassination, but he was shot and killed by Jack Ruby two days later. The FBI and the Warren Commission both concluded Oswald had acted alone, but conspiracy theories about the assassination still persist. After Kennedy's death, Congress enacted many of his proposals, including the Civil Rights Act of 1964 and the Revenue Act of 1964. Kennedy ranks highly in polls of U.S. presidents with historians and the general public. His personal life has also been the focus of considerable sustained interest following public revelations in the 1970s of his chronic health ailments and extramarital affairs.

The reports are collected from four different body parts or primary sites from multiple patients. The distribution of reports across different primary diagnoses and primary sites is reported in tab:report-distribution. The dataset was developed in three steps as follows.\nCollecting pathology reports: The total of 11,112 pathology reports were downloaded from NCI's Genomic Data Commons (GDC) dataset in PDF format BIBREF9 . Out of all PDF files, 1,949 reports were selected across multiple patients from four specific primary sites—thymus, testis, lung, and kidney. The selection was primarily made based on the quality of PDF files.\nCleaning reports: The next step was to extract the text content from these reports. Due to the significant time expense of manually re-typing all the pathology reports, we developed a new strategy to prepare our dataset. We applied an Optical Character Recognition (OCR) software to convert the PDF reports to text files. Then, we manually inspected all generated text files to fix any grammar/spelling issues and irrelevant characters as an artefact produced by the OCR system.\nSplitting into training-testing data: We split the cleaned reports into 70% and 30% for training and testing, respectively. This split resulted in 1,364 training, and 585 testing reports.\nThe dataset was developed in three steps as follows.

The ACPT metric appears to be a solid metric in evaluating fluency.",
        "evidence": "We present the percentage of answers to each question in Figure FIGREF38. The green bars illustrate how well the adversarial examples paraphrase the original ones; blue how natural the adversarial examples read; and red whether the sentiment of the adversarial examples is consistent compared to the original.\nLooking at the performance of the original sentences (“(a) Original samples”), we see that their language is largely fluent and their sentiment is generally consistent to the original examples', although it's worth noting that the review sentiment of imdb400 can be somewhat ambiguous (63% agreement). We think this is due to movie reviews being more descriptive and therefore creating potential ambiguity in their expression of sentiment.\nOn content preservation (criterion (b); green bars), all methods produce poor paraphrases on yelp50. For imdb400, however, the results are more promising; adversarial examples generated by HotFlip, in particular, are good, even at T2.\nNext we look at fluency (criterion (c); blue bars). We see a similar trend: performance in imdb400 is substantially better than yelp50. In fact we see almost no decrease in fluency in the adversarial examples compared to the original in imdb400. In yelp50, HotFlip and AutoEncoder are fairly competitive, producing adversarial examples that are only marginally less fluent compared to the original at T0. At T2, however, these methods begin to trade off fluency. All in all, the paraphrasability and fluency surveys suggest that imdb400 is an easier dataset for adversarial experiments, and it is the predominant dataset used by most studies.\nLastly, we consider sentiment preservation (criterion (d); red bars). All methods perform poorly at preserving the original sentiment on both yelp50 and imdb400 datasets. The artifact is arguably more profound on shorter inputs, as the original examples in imdb400 have lower agreement in the first place (yelp50 vs. imdb400: 86% vs. 63%). Again both HotFlip and AutoEncoder are the better methods here (interestingly, we observe an increase in agreement as their attacking performance increases from T0 and T2).\nSummarising our findings, HotFlip is generally the best method across all criteria, noting that its adversarial examples, however, have poor transferability. TYC generates good black-box adversarial examples but do not do well in terms of content preservation and fluency. AutoEncoder produces comparable results with HotFlip for meeting the four criteria and generates examples that generalise reasonably, but it is very sensitive to the increase of training examples for the target classifier. The ACPT metric appears to be effective in evaluating fluency, as we see good agreement with human evaluation. All said, we found that all methods tend to produce adversarial examples that do not preserve their original sentiments, revealing that these methods in a way “cheat” by simply flipping the sentiments of the original sentences to fool the classifier, and therefore the adversarial examples might be ineffective for adversarial training, as they are not examples that reveal potential vulnerabilities in the classifier.\nComparing automatic evaluation and human evaluation results, we found that the SEM scores are generally consistent with the human evaluation results on semantic preservation, while the BLEU score is less effective as evidenced by the high BLEU score of HOTFLIP on yelp50 and poor paraphrasing performance in the same settings. The ACPT metric appears to be a solid metric in evaluating fluency, as we see a good agreement with human evaluation across the three attacking methods.",

        "question": "Why does the time of sunrise vary throughout the year?",
        "evidence": "Although the Sun appears to \"rise\" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion caused many cultures to have mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century.\nAstronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon. However, the term sunrise commonly refers to periods of time both before and after this point:\nTwilight, the period in the morning during which the sky is brightening, but the Sun is not yet visible. The beginning of morning twilight is called astronomical dawn.\nThe period after the Sun rises during which striking colors and atmospheric effects are still seen.\nThe timing of sunrise varies throughout the year and is also affected by the viewer's latitude and longitude, altitude, and time zone. These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun, and the Earth and Moon's paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise.\nIn late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.\nVariations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly.\nAccounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.",

        "question": "What is the major factor that influences the efficiency of machine translation system？",
        "answer": "The efficiency of an MT system depends on two major factors: the availability and size of parallel corpus used for training and the syntactic divergence between the two languages.",
        "evidence": "The use of RNNs in the field of Statistical Machine Translation (SMT) has revolutionised the approaches to automated translation. As opposed to traditional shallow SMT models, which require a lot of memory to run, these neural translation models require only a small fraction of memory used, about 5% BIBREF0 . Also, neural translation models are optimized such that every module is trained to jointly improve translation quality. With that being said, one of the main downsides of neural translation models is the heavy corpus requirement in order to ensure learning of deeper contexts. This is where the application of these encoder decoder architectures in translation to and/or from morphologically rich languages takes a severe hit.\nFor any language pair, the efficiency of an MT system depends on two major factors: the availability and size of parallel corpus used for training and the syntactic divergence between the two languages i.e morphological richness, word order differences, grammatical structure etc. BIBREF0 . The main differences between the languages stem from the fact that languages similar to English are predominantly fusional languages whereas many of the morphologically rich languages are agglutinative in nature. The nature of morphologically rich languages being structurally and semantically discordant from languages like English adds to the difficulty of SMT involving such languages.\nIn morphologically rich languages, any suffix can be added to any verb or noun to simply mean one specific thing about that particular word that the suffix commonly represents (agglutination). This means that there exists a lot of inflectional forms of the same noun and verb base words, conveying similar notions. For example, in Tamil, there are at least 30,000 inflectional forms of any given verb and about 5,000 forms of inflectional forms for any noun. The merged words carry information about part of speech (POS) tags, tense, plurality and so forth that are important for analyzing text for Machine Translation (MT). Not only are these hidden meanings not captured, the corresponding root words are trained as different units, thereby increasing the complexity of developing such MT systems BIBREF1 .\nTo add to the complexities of being a morphologically rich language, there are several factors unique to Tamil that make translation very difficult. The availability of parallel corpus for Tamil is very scarce. Most of the other models in the field of English–Tamil MT have made use of their own translation corpora that were manually created for the purposes of research. Most of these corpora are not available online for use.\nAnother issue specific to Tamil is the addition of suffix characters included to the words in the language for smoothness in pronunciation. These characters are of so many different types; there is a unique suffix for each and every consonant in the language. These suffixes degrade performance of MT because the same words with different such pronounciation-based suffixes will be taken as different words in training.\nAlso to take into consideration is the existence of two different forms of the language being used. Traditionally defined Tamil and its pronunciations aren't acoustically pleasing to use. There's no linguistic flow between syllables and its usage in verbal communication is time consuming. Therefore, there exists two forms of the language, the written form, rigid in structure and syntax, and the spoken form, in which the flow and pace of the language is given priority over syntax and correctness of spelling. This divide leads to the corpus having 2 different versions of the language that increase the vocabulary even with the same words. This can be evidently seen in the corpus between the sentences used in the Bible, which is in traditional Tamil and sentences from movie subtitles, being in spoken Tamil format.\nTo account for such difficulties, a trade-off between domain specificity and size of the corpus is integral in building an English–Tamil neural MT system.\nFor any language pair, the efficiency of an MT system depends on two major factors: the availability and size of parallel corpus used for training and the syntactic divergence between the two languages i.e morphological richness, word order differences, grammatical structure etc. (Cho et al. 2014a).",

        "question": "What framework do they propose?",
        "answer": "A framework which emits both insertions and deletions.",
        "evidence": "Neural sequence models BIBREF0, BIBREF1 typically generate outputs in an autoregressive left-to-right manner. These models have been successfully applied to a range of task, for example machine translation BIBREF2. They often rely on an encoder that processes the source sequence, and a decoder that generates the output sequence conditioned on the output of the encoder. The decoder will typically generate the target sequence one token at a time, in an autoregressive left-to-right fashion.\nRecently, research in insertion-based non- or partially- autoregressive models has spiked BIBREF3, BIBREF4, BIBREF5, BIBREF6. These model are more flexible than their autoregressive counterparts. They can generate sequences in any order, and can benefit from parallel token generation. They can learn complex orderings (e.g., tree orderings) and may be more applicable to task like cloze question answering BIBREF6 and text simplification, where the order of generation is not naturally left to right, and the source sequence might not be fully observed. One recently proposed approach is the Insertion Transformer BIBREF3, where the target sequence is modelled with insertion-edits. As opposed to traditional sequence-to-sequence models, the Insertion Transformer can generate sequences in any arbitrary order, where left-to-right is a special case. Additionally, during inference, the model is endowed with parallel token generation capabilities. The Insertion Transformer can be trained to follow a soft balanced binary tree order, thus allowing the model to generate $n$ tokens in $O(\\log _2 n)$ iterations.\nIn this work we propose to generalize this insertion-based framework, we present a framework which emits both insertions and deletions. Our Insertion-Deletion Transformer consists of an insertion phase and a deletion phase that are executed iteratively. The insertion phase follows the typical insertion-based framework BIBREF3. However, in the deletion phase, we teach the model to do deletions with on-policy training. We sample an input sequence on-policy from the insertion model (with on-policy insertion errors), and teach the deletion model its appropriate deletions.\nThis insertion-deletion framework allows for flexible sequence generation, parallel token generation and text editing. In a conventional insertion-based model, if the model makes a mistake during generation, this cannot be undone. Introducing the deletion phase makes it possible to undo the mistakes made by the insertion model, since it is trained on the on-policy errors of the insertion phase. The deletion model extension also enables the framework to efficiently handle tasks like text simplification and style transfer by starting the decoding process from the original source sequence.\nA concurrent work was recently proposed, called the Levenshtein Transformer (LevT) BIBREF7. The LevT framework also generates sequences with insertion and deletion operations. Our approach has some important distinctions and can be seen as a simplified version, for both the architecture and the training algorithm. The training algorithm used in the LevT framework uses an expert policy. This expert policy requires dynamic programming to minimize Levenshtein distance between the current input and the target. This approach was also explored by BIBREF8, BIBREF9. Their learning algorithm arguably adds more complexity than needed over the simple on-policy method we propose. The LevT framework consists of three stages, first the number of tokens to be inserted is predicted, then the actual tokens are predicted, and finally the deletion actions are emitted. The extra classifier to predict the number of tokens needed to be inserted adds an additional Transformer pass to each generation step. In practice, it is also unclear whether the LevT exhibits speedups over an insertion-based model following a balanced binary tree order. In contrast, our Insertion-Deletion framework only has one insertion phase and one deletion phase, without the need to predict the number of tokens needed to be inserted. This greatly simplifies the model architecture, training procedure and inference runtime.\nAn alternative approach for text editing is proposed by BIBREF10, which they dub Deliberation Networks. This work also acknowledges the potential benefits from post-editing output sequences and proposes a two-phase decoding framework to facilitate this.\nIn this paper, we present the insertion-deletion framework as a proof of concept by applying it to two synthetic character-based translation tasks and showing it can significantly increase the BLEU score over the insertion-only framework.\nIn this work we propose to generalize this insertion-based framework, we present a framework which emits both insertions and deletions.",

These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nNeural network based models have been widely exploited with the prosperities of Deep Learning [Bengio et al., 2013] and achieved inspiring performances on many NLP tasks, such as text classification [Chen et al., 2015; Liu et al., 2015a], semantic matching [Liu et al., 2016d; Liu et al., 2016a] and machine translation [Sutskever et al., 2014].",

Indonesia declared independence on 17 August 1945 and subsequently fought a bitter war against the returning Dutch; the Philippines was granted independence by the United States in 1946; Burma secured their independence from Britain in 1948, and the French were driven from Indochina in 1954 after a bitterly fought war (the Indochina War) against the Vietnamese nationalists. The United Nations provided a forum for nationalism, post-independent self-definition, nation-building and the acquisition of territorial integrity for many newly independent nations.\n\nDuring the Cold War, countering the threat of communism was a major theme in the decolonisation process. After suppressing the communist insurrection during the Malayan Emergency from 1948 to 1960, Britain granted independence to Malaya and later, Singapore, Sabah and Sarawak in 1957 and 1963 respectively within the framework of the Federation of Malaysia. In one of the most bloody single incidents of violence in Cold War Southeast Asia, General Suharto seized power in Indonesia in 1965 and initiated a massacre of approximately 500,000 alleged members of the Communist Party of Indonesia (PKI).\n\nFollowing the independence of the Indochina states with the battle of Dien Bien Phu, North Vietnamese attempts to conquer South Vietnam resulted in the Vietnam War. The conflict spread to Laos and Cambodia and heavy intervention from the United States. By the war's end in 1975, all these countries were controlled by communist parties. After the communist victory, two wars between communist states—the Cambodian–Vietnamese War of 1975–89 and the Sino-Vietnamese War of 1979—were fought in the region. The victory of the Khmer Rouge in Cambodia resulted in the Cambodian genocide.\n\nIn 1975, Portuguese rule ended in East Timor. However, independence was short-lived as Indonesia annexed the territory soon after. However, after more than 20 years of fighting Indonesia, East Timor won its independence and was recognised by the UN in 2002.

        "evidence": "We compared our full method (TextTiling with heuristic-max based on embeddings trained by virtual sentences) with several baselines:\nRandom. We randomly segmented conversation sessions. In this baseline, we were equipped with the prior probability of segmentation.\nMMD. We applied the MinMax-Dotplotting (MMD) approach proposed by Ye et al. BIBREF24 . We ran the executable program provided by the authors.\nTextTiling w/ tf INLINEFORM0 idf features. We implemented TextTiling ourselves according to BIBREF12 .\nWe tuned the hyperparameter INLINEFORM0 in Equation ()on the validation set to make the number of segmentation close to that of manual annotation, and reported precision, recall, and the F-score on the test set in Table TABREF18 . As seen, our approach significantly outperforms baselines by a large margin in terms of both precision and recall. Besides, we can see that MMD obtains low performance, which is mainly because the approach cannot be easily adapted to other datasets like short sentences of conversation utterances. In summary, we achieve an INLINEFORM1 -score higher than baseline methods by more than 20%, showing the effectiveness of enhancing TextTiling with modern word embeddings.\nWe further conducted in-depth analysis of different strategies of training word-embeddings and matching heuristics in Table TABREF21 . For word embeddings, we trained them on the 3M-sentence dataset with three strategies: (1) virtual-sentence context proposed in our paper; (2) within-sentence context, where all words (except the current one) within a sentence (either a query or reply) are regarded as the context; (3) window-based context, which is the original form of BIBREF25 : the context is the words in a window (previous 2 words and future 2 words in the sentence). We observe that our virtual-sentence strategy consistently outperforms the other two in all three matching heuristics. The results suggest that combining a query and a reply does provide more information in learning dialogue-specific word embeddings.\nRegarding matching heuristics, we find that in the second and third strategies of training word embeddings, the complicated heuristic-max method yields higher INLINEFORM0 -scores than simple sum pooling by 2–3%. However, for the virtual-sentence strategy, heuristic-max is slightly worse than the sum pooling. (The degradation is only 0.1% and not significant.) This is probably because both heuristic-max and virtual sentences emphasize the rich interaction between a query and its corresponding reply; combining them does not result in further gain.\nWe also notice that heuristic-avg is worse than other similarity measures. As this method is mathematically equivalent to the average of word-by-word similarity, it may have an undesirable blurring effect.\nTo sum up, our experiments show that both the proposed embedding learning approach and the similarity heuristic are effective for session segmentation. The embedding-enhanced TextTiling approach largely outperforms baselines.\nWe conducted an external experiment to show the effect of session segmentation in dialogue systems. We integrated the segmentation mechanism into a state-of-the-practice retrieval-based system and evaluated the results by manual annotation, similar to our previous work BIBREF27 , BIBREF31 , BIBREF32 .\nConcretely, we compared our session segmentation with fixed-length context, used in BIBREF11 . That is to say, the competing method always regards two previous utterances as context. We hired three workers to annotate the results with three integer scores (0–2 points, indicating bad, borderline, and good replies, respectively.) We sampled 30 queries from the test set of 100 sessions. For each query, we retrieved 10 candidates and computed p@1 and nDCG scores BIBREF33 (averaged over three annotators). Provided with previous utterances as context, each worker had up to 1000 sentences to read during annotation.\nTable TABREF26 presents the results of the dialogue system with session segmentation. As demonstrated, our method outperforms the simple fixed-context approach in terms of both metrics. We computed the inner-annotator agreement: std INLINEFORM0 0.309; 3-discrete-class Fleiss' kappa score INLINEFORM1 0.411, indicating moderate agreement BIBREF34 .\nCase Study. We present a case study on our website: https://sites.google.com/site/sessionsegmentation/. From the case study, we see that the proposed approach is able to segment the dialogue session appropriately, so as to better utilize background information from a conversation session.\nIn this paper, we addressed the problem of session segmentation for open-domain dialogue systems. We proposed an embedding-enhanced TextTiling approach, where we trained embeddings with the novel notion of virtual sentences; we also proposed several heuristics for similarity measure. Experimental results show that both our embedding learning and similarity measuring are effective in session segmentation, and that with our approach, we can improve the performance of a retrieval-based dialogue system.\nWe thank anonymous reviewers for useful comments and Jingbo Zhu for sharing the MMD executable program.

Each method of casting on can look and feel slightly different (such as various levels of stretchiness and flexibility) so most knitters have their preferred cast on method. Many use the long-tail cast on method which can work for many projects.  First, measure the length of yarn that is about 4 times as long as the width of your project. For example, if the width of your project is 10 inches, measure out a 40 inch piece of yarn. Next, time a slip knot. Then, place the slip knot on your dominant hand’s needle with the yarn tail closest to you (the tail is the length you measured out). Hold both strands of yarn with your non-dominant hand. Spread the two strands of yarn out with your thumb and forefinger, then bring the knitting needle in your right hand to the front of the tail of yarn draped over your thumb. Bring the needle back, up and through the loop toward your thumb loop, then push the needle back and under the forefinger loop, allowing the needle to catch the forefinger loop and allowing the thumb loop to fall off under the needle. That’s your first cast on stitch. Repeat the steps for the total number of stitches you need.",

        "question": "What standard evaluation metrics are used to evaluate the performance of their proposed model?",
        "answer": "Mean reciprocal rank (MRR) and Hits@1.3 For each metric, the higher value indicates better ranking performance.",
        "evidence": "Datasets: We use two recent benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . These two datasets are created to avoid reversible relation problems, thus the prediction task becomes more realistic and hence more challenging BIBREF18 . Table TABREF7 presents the statistics of WN18RR and FB15k-237.\nEvaluation protocol: Following BIBREF3 , for each valid test triple INLINEFORM0 , we replace either INLINEFORM1 or INLINEFORM2 by each of all other entities to create a set of corrupted triples. We use the “Filtered” setting protocol BIBREF3 , i.e., not taking any corrupted triples that appear in the KG into accounts. We rank the valid test triple and corrupted triples in descending order of their scores. We employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions). Lower MR, higher MRR or higher Hits@10 indicate better performance. Final scores on the test set are reported for the model obtaining the highest Hits@10 on the validation set.\nTraining protocol: We use the common Bernoulli strategy BIBREF20 , BIBREF21 when sampling invalid triples. For WN18RR, BIBREF22 found a strong evidence to support the necessity of a WordNet-related semantic setup, in which they averaged pre-trained word embeddings for word surface forms within the WordNet to create synset embeddings, and then used these synset embeddings to initialize entity embeddings for training their TransE association model. We follow this evidence in using the pre-trained 100-dimensional Glove word embeddings BIBREF23 to train a TransE model on WN18RR.\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 . For ConvKB, we use a new process of training up to 100 epochs and monitor the Hits@10 score after every 10 training epochs to choose optimal hyper-parameters with the Adam initial learning rate in INLINEFORM0 and the number of filters INLINEFORM1 in INLINEFORM2 . We obtain the highest Hits@10 scores on the validation set when using N= 400 and the initial learning rate INLINEFORM3 on WN18RR; and N= 100 and the initial learning rate INLINEFORM4 on FB15k-237.\nLike in ConvKB, we use the same pre-trained entity and relation embeddings produced by TransE to initialize entity and relation embeddings in our CapsE for both WN18RR and FB15k-237 ( INLINEFORM0 ). We set the batch size to 128, the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM1 ), and the number of iterations in the routing algorithm INLINEFORM2 in INLINEFORM3 . We run CapsE up to 50 epochs and monitor the Hits@10 score after each 10 training epochs to choose optimal hyper-parameters. The highest Hits@10 scores for our CapsE on the validation set are obtained when using INLINEFORM4 , INLINEFORM5 and the initial learning rate at INLINEFORM6 on WN18RR; and INLINEFORM7 , INLINEFORM8 and the initial learning rate at INLINEFORM9 on FB15k-237.\nDataset: We use the SEARCH17 dataset BIBREF12 of query logs of 106 users collected by a large-scale web search engine. A log entity consists of a user identifier, a query, top-10 ranked documents returned by the search engine and clicked documents along with the user's dwell time. BIBREF12 constructed short-term (session-based) user profiles and used the profiles to personalize the returned results. They then employed the SAT criteria BIBREF26 to identify whether a returned document is relevant from the query logs as either a clicked document with a dwell time of at least 30 seconds or the last clicked document in a search session (i.e., a SAT click). After that, they assigned a INLINEFORM0 label to a returned document if it is a SAT click and also assigned INLINEFORM1 labels to the remaining top-10 documents. The rank position of the INLINEFORM2 labeled documents is used as the ground truth to evaluate the search performance before and after re-ranking.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set BIBREF12 . The training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.\nEvaluation protocol: Our CapsE is used to re-rank the original list of documents returned by a search engine as follows: (i) We train our model and employ the trained model to calculate the score for each INLINEFORM0 triple. (ii) We then sort the scores in the descending order to obtain a new ranked list. To evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1. For each metric, the higher value indicates better ranking performance.\nWe compare CapsE with the following baselines using the same experimental setup: (1) SE: The original rank is returned by the search engine. (2) CI BIBREF27 : This baseline uses a personalized navigation method based on previously clicking returned documents. (3) SP BIBREF9 , BIBREF11 : A search personalization method makes use of the session-based user profiles. (4) Following BIBREF12 , we use TransE as a strong baseline model for the search personalization task. Previous work shows that the well-known embedding model TransE, despite its simplicity, obtains very competitive results for the knowledge graph completion BIBREF28 , BIBREF29 , BIBREF14 , BIBREF30 , BIBREF15 . (5) The CNN-based model ConvKB is the most closely related model to our CapsE.\nEmbedding initialization: We follow BIBREF12 to initialize user profile, query and document embeddings for the baselines TransE and ConvKB, and our CapsE.\nWe train a LDA topic model BIBREF31 with 200 topics only on the relevant documents (i.e., SAT clicks) extracted from the query logs. We then use the trained LDA model to infer the probability distribution over topics for every returned document. We use the topic proportion vector of each document as its document embedding (i.e. INLINEFORM0 ). In particular, the INLINEFORM1 element ( INLINEFORM2 ) of the vector embedding for document INLINEFORM3 is: INLINEFORM4 where INLINEFORM5 is the probability of the topic INLINEFORM6 given the document INLINEFORM7 .\nWe also represent each query by a probability distribution vector over topics. Let INLINEFORM0 be the set of top INLINEFORM1 ranked documents returned for a query INLINEFORM2 (here, INLINEFORM3 ). The INLINEFORM4 element of the vector embedding for query INLINEFORM5 is defined as in BIBREF12 : INLINEFORM6 , where INLINEFORM7 is the exponential decay function of INLINEFORM8 which is the rank of INLINEFORM9 in INLINEFORM10 . And INLINEFORM11 is the decay hyper-parameter ( INLINEFORM12 ). Following BIBREF12 , we use INLINEFORM13 . Note that if we learn query and document embeddings during training, the models will overfit to the data and will not work for new queries and documents. Thus, after the initialization process, we fix (i.e., not updating) query and document embeddings during training for TransE, ConvKB and CapsE.\nIn addition, as mentioned by BIBREF9 , the more recently clicked document expresses more about the user current search interest. Hence, we make use of the user clicked documents in the training set with the temporal weighting scheme proposed by BIBREF11 to initialize user profile embeddings for the three embedding models.\nHyper-parameter tuning: For our CapsE model, we set batch size to 128, and also the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM0 ). The number of iterations in the routing algorithm is set to 1 ( INLINEFORM1 ). For the training model, we use the Adam optimizer with the initial learning rate INLINEFORM2 INLINEFORM3 INLINEFORM4 INLINEFORM5 INLINEFORM6 INLINEFORM7 . We also use ReLU as the activation function INLINEFORM8 . We select the number of filters INLINEFORM9 . We run the model up to 200 epochs and perform a grid search to choose optimal hyper-parameters on the validation set. We monitor the MRR score after each training epoch and obtain the highest MRR score on the validation set when using INLINEFORM10 and the initial learning rate at INLINEFORM11 .\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 and then follow their training protocols to tune hyper-parameters for TransE and ConvKB, respectively. We also monitor the MRR score after each training epoch and attain the highest MRR score on the validation set when using margin = 5, INLINEFORM0 -norm and SGD learning rate at INLINEFORM1 for TransE; and INLINEFORM2 and the Adam initial learning rate at INLINEFORM3 for ConvKB.\nTo evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1.3 For each metric, the higher value indicates better ranking performance.",

        "question": "Given this paragraph about the first tour de france, who won the first race",

The plan was a five-stage race from 31 May to 5 July, starting in Paris and stopping in Lyon, Marseille, Bordeaux, and Nantes before returning to Paris. Toulouse was added later to break the long haul across southern France from the Mediterranean to the Atlantic. Stages would go through the night and finish next afternoon, with rest days before riders set off again. But this proved too daunting and the costs too great for most and only 15 competitors had entered. Desgrange had never been wholly convinced and he came close to dropping the idea. Instead, he cut the length to 19 days, changed the dates to 1 to 19 July, and offered a daily allowance to those who averaged at least 20 kilometres per hour (12 mph) on all the stages, equivalent to what a rider would have expected to earn each day had he worked in a factory. He also cut the entry fee from 20 to 10 francs and set the first prize at 12,000 francs and the prize for each day's winner at 3,000 francs. The winner would thereby win six times what most workers earned in a year. That attracted between 60 and 80 entrants – the higher number may have included serious inquiries and some who dropped out – among them not just professionals but amateurs, some unemployed, and some simply adventurous.\n\nDesgrange seems not to have forgotten the Dreyfus Affair that launched his race and raised the passions of his backers. He announced his new race on 1 July 1903 by citing the writer Émile Zola, whose open letter J'Accuse…! led to Dreyfus's acquittal, establishing the florid style he used henceforth.\n\nThe first Tour de France started almost outside the Café Reveil-Matin at the junction of the Melun and Corbeil roads in the village of Montgeron. It was waved away by the starter, Georges Abran, at 3:16 p.m. on 1 July 1903. L'Auto hadn't featured the race on its front page that morning.[n 3]\n\nAmong the competitors were the eventual winner, Maurice Garin, his well-built rival Hippolyte Aucouturier, the German favourite Josef Fischer, and a collection of adventurers, including one competing as \"Samson\".[n 4]\n\nMany riders dropped out of the race after completing the initial stages, as the physical effort the tour required was just too much. Only a mere 24 entrants remained at the end of the fourth stage. The race finished on the edge of Paris at Ville d'Avray, outside the Restaurant du Père Auto, before a ceremonial ride into Paris and several laps of the Parc des Princes. Garin dominated the race, winning the first and last two stages, at 25.68 kilometres per hour (15.96 mph). The last rider, Millocheau, finished 64h 47m 22s behind him.\n\nL'Auto's mission was accomplished, as circulation of the publication doubled throughout the race, making the race something much larger than Desgrange had ever hoped for.",

Given a set of evaluation documents, each having a known correct label from a closed set of labels (often referred to as the “gold-standard”), and a predicted label for each document from the same set, the document-level accuracy is the proportion of documents that are correctly labeled over the entire evaluation collection. This is the most frequently reported metric and conveys the same information as the error rate, which is simply the proportion of documents that are incorrectly labeled (i.e. INLINEFORM0 ).\nAuthors sometimes provide a per-language breakdown of results. There are two distinct ways in which results are generally summarized per-language: (1) precision, in which documents are grouped according to their predicted language; and (2) recall, in which documents are grouped according to what language they are actually written in. Earlier work has tended to only provide a breakdown based on the correct label (i.e. only reporting per-language recall). This gives us a sense of how likely a document in any given language is to be classified correctly, but does not give an indication of how likely a prediction for a given language is of being correct. Under the monolingual assumption (i.e. each document is written in exactly one language), this is not too much of a problem, as a false negative for one language must also be a false positive for another language, so precision and recall are closely linked. Nonetheless, authors have recently tended to explicitly provide both precision and recall for clarity. It is also common practice to report an F-score INLINEFORM0 , which is the harmonic mean of precision and recall. The F-score (also sometimes called F1-score or F-measure) was developed in IR to measure the effectiveness of retrieval with respect to a user who attaches different relative importance to precision and recall BIBREF376 . When used as an evaluation metric for classification tasks, it is common to place equal weight on precision and recall (hence “F1”-score, in reference to the INLINEFORM1 hyper-parameter, which equally weights precision and recall when INLINEFORM2 ).\nGiven a set of evaluation documents, each having a known correct label from a closed set of labels (often referred to as the “gold-standard”), and a predicted label for each document from the same set, the document-level accuracy is the proportion of documents that are correctly labeled over the entire evaluation collection.

        "answer": "We have stressed and clarified our key contribution. Please check our General Response 1.We focus on improving the generalization and transfer learning ability of the current offline meta-RL methods, which is extremely important component of intelligence.",
        "evidence": "Deep reinforcement learning (RL) has achieved many successes with human-or superhuman-level performance across a wide range of complex domains. However, all these major breakthroughs focus on finding the bestperforming strategy by trial-and-error interactions with a single environment, which poses severe constraints for scenarios such as healthcare, autonomous driving and controlled-environment agriculture where safety is paramount. Moreover, these RL algorithms require tremendous explorations and training samples, and are also prone to over-fitting to the target task, resulting in poor generalization and robustness. To make RL truly practical in many real-world applications, a new paradigm with better safety, sample efficiency and generalization is in need.\nOffline meta-RL, as a marriage between offline RL and meta-RL, has emerged as a promising candidate to address the aforementioned challenges. Like supervised learning, offline RL restricts the agent to solely learn from fixed and limited data, circumventing potentially risky explorations. Additionally, offline algorithms are by nature off-policy, which by reusing prior experience, have proven to achieve far better sample efficiency than on-policy counterparts.\nMeta-RL, on the other hand, exploits the shared structure of a distribution of tasks and enables the agent to adapt to new tasks with minimal data. One popular approach is by learning a single universal policy conditioned on a latent task representation, known as context-based method. Alternatively, the shared skills can be learned with a meta-controller.\nIn this work we restrict our attention on context-based offline meta-RL (COMRL), an understudied framework with a few existing algorithms, for a set of tasks that differ in reward or transition dynamics. One major challenge associated with this scenario is termed Markov Decision Process (MDP) ambiguity, namely the task-conditioned policies spuriously correlate task identity with state-action pairs due to biased distribution of the fixed datasets. This phenomenon can be interpreted as a special form of memorization problem in classical meta-learning, where the value and policy functions overfit the training distributions without capturing causality from reward and transition functions, often leading to degenerate task representations and poor generalization. To alleviate such over-fitting, proposes a framework named FOCAL which decouples the learning of task inference from control by using self-supervised distance metric learning. However, they made a strong assumption on the existence of an injective map from each transistion tuple {s, a, s , r} to its task identity. Under extreme scenarios such as sparse reward, where a considerable portion of aggregated experience provides little information regarding task identity, efficient and robust learning of task representations is still challenging.\nTo address the aforementioned problem, in this paper we propose intra-task attention mechanism and inter-task contrastive learning objectives to achieve robust task inference. More specifically, for each task, we apply a batch-wise gated attention to recalibrate the weights of transition samples, and use sequence-wise self-attention to better capture the correlation within the transition (state, action, reward) dimensions. In addition, we implemented a matrix-form objective of the Momentum Contrast (MoCo) for task-level representation learning, by replacing its dictionary queue with a meta-batch sampled on-the-fly. We provide theoretical analyses showing that our objective serves as a better surrogate than naive contrastive loss for task inference and the proposed attention mechanism on top can also reduce the variance of task representation. Moreover, empirical evaluations demonstrate that the proposed design choices of attention and contrastive learning mechanisms not only boost the performance of task inference, but also significantly improve its robustness against sparse reward and distribution shift. We name our new method FOCAL++.\nTo make RL truly practical in many real-world applications, a new paradigm with better safety, sample efficiency and generalization is in need.",

        "question": "What factors contributed to the decline of AI research in the 1970s?",
        "evidence": "TThe first AI winter 1974–1980\nIn the 1970s, AI was subject to critiques and financial setbacks. AI researchers had failed to appreciate the difficulty of the problems they faced. Their tremendous optimism had raised expectations impossibly high, and when the promised results failed to materialize, funding for AI disappeared. At the same time, the field of connectionism (or neural nets) was shut down almost completely for 10 years by Marvin Minsky's devastating criticism of perceptrons. Despite the difficulties with public perception of AI in the late 70s, new ideas were explored in logic programming, commonsense reasoning and many other areas.\n\nThe problems\nIn the early seventies, the capabilities of AI programs were limited. Even the most impressive could only handle trivial versions of the problems they were supposed to solve; all the programs were, in some sense, \"toys\". AI researchers had begun to run into several fundamental limits that could not be overcome in the 1970s. Although some of these limits would be conquered in later decades, others still stymie the field to this day.\n\nLimited computer power: There was not enough memory or processing speed to accomplish anything truly useful. For example, Ross Quillian's successful work on natural language was demonstrated with a vocabulary of only twenty words, because that was all that would fit in memory. Hans Moravec argued in 1976 that computers were still millions of times too weak to exhibit intelligence. He suggested an analogy: artificial intelligence requires computer power in the same way that aircraft require horsepower. Below a certain threshold, it's impossible, but, as power increases, eventually it could become easy. With regard to computer vision, Moravec estimated that simply matching the edge and motion detection capabilities of human retina in real time would require a general-purpose computer capable of 109 operations/second (1000 MIPS). As of 2011, practical computer vision applications require 10,000 to 1,000,000 MIPS. By comparison, the fastest supercomputer in 1976, Cray-1 (retailing at $5 million to $8 million), was only capable of around 80 to 130 MIPS, and a typical desktop computer at the time achieved less than 1 MIPS.\nIntractability and the combinatorial explosion. In 1972 Richard Karp (building on Stephen Cook's 1971 theorem) showed there are many problems that can probably only be solved in exponential time (in the size of the inputs). Finding optimal solutions to these problems requires unimaginable amounts of computer time except when the problems are trivial. This almost certainly meant that many of the \"toy\" solutions used by AI would probably never scale up into useful systems.\nCommonsense knowledge and reasoning. Many important artificial intelligence applications like vision or natural language require simply enormous amounts of information about the world: the program needs to have some idea of what it might be looking at or what it is talking about. This requires that the program know most of the same things about the world that a child does. Researchers soon discovered that this was a truly vast amount of information. No one in 1970 could build a database so large and no one knew how a program might learn so much information.\nMoravec's paradox: Proving theorems and solving geometry problems is comparatively easy for computers, but a supposedly simple task like recognizing a face or crossing a room without bumping into anything is extremely difficult. This helps explain why research into vision and robotics had made so little progress by the middle 1970s.\nThe frame and qualification problems. AI researchers (like John McCarthy) who used logic discovered that they could not represent ordinary deductions that involved planning or default reasoning without making changes to the structure of logic itself. They developed new logics (like non-monotonic logics and modal logics) to try to solve the problems.\nThe end of funding\nSee also: AI winter\nThe agencies which funded AI research (such as the British government, DARPA and NRC) became frustrated with the lack of progress and eventually cut off almost all funding for undirected research into AI. The pattern began as early as 1966 when the ALPAC report appeared criticizing machine translation efforts. After spending 20 million dollars, the NRC ended all support. In 1973, the Lighthill report on the state of AI research in England criticized the utter failure of AI to achieve its \"grandiose objectives\" and led to the dismantling of AI research in that country. (The report specifically mentioned the combinatorial explosion problem as a reason for AI's failings.) DARPA was deeply disappointed with researchers working on the Speech Understanding Research program at CMU and canceled an annual grant of three million dollars. By 1974, funding for AI projects was hard to find.\n\nHans Moravec blamed the crisis on the unrealistic predictions of his colleagues. \"Many researchers were caught up in a web of increasing exaggeration.\" However, there was another issue: since the passage of the Mansfield Amendment in 1969, DARPA had been under increasing pressure to fund \"mission-oriented direct research, rather than basic undirected research\". Funding for the creative, freewheeling exploration that had gone on in the 60s would not come from DARPA. Instead, the money was directed at specific projects with clear objectives, such as autonomous tanks and battle management systems.\n\nCritiques from across campus\nSee also: Philosophy of artificial intelligence\nSeveral philosophers had strong objections to the claims being made by AI researchers. One of the earliest was John Lucas, who argued that Gödel's incompleteness theorem showed that a formal system (such as a computer program) could never see the truth of certain statements, while a human being could. Hubert Dreyfus ridiculed the broken promises of the 1960s and critiqued the assumptions of AI, arguing that human reasoning actually involved very little \"symbol processing\" and a great deal of embodied, instinctive, unconscious \"know how\". John Searle's Chinese Room argument, presented in 1980, attempted to show that a program could not be said to \"understand\" the symbols that it uses (a quality called \"intentionality\"). If the symbols have no meaning for the machine, Searle argued, then the machine can not be described as \"thinking\".\n\nThese critiques were not taken seriously by AI researchers, often because they seemed so far off the point. Problems like intractability and commonsense knowledge seemed much more immediate and serious. It was unclear what difference \"know how\" or \"intentionality\" made to an actual computer program. Minsky said of Dreyfus and Searle \"they misunderstand, and should be ignored.\" Dreyfus, who taught at MIT, was given a cold shoulder: he later said that AI researchers \"dared not be seen having lunch with me.\" Joseph Weizenbaum, the author of ELIZA, felt his colleagues' treatment of Dreyfus was unprofessional and childish. Although he was an outspoken critic of Dreyfus' positions, he \"deliberately made it plain that theirs was not the way to treat a human being.\"\n\nWeizenbaum began to have serious ethical doubts about AI when Kenneth Colby wrote a \"computer program which can conduct psychotherapeutic dialogue\" based on ELIZA. Weizenbaum was disturbed that Colby saw a mindless program as a serious therapeutic tool. A feud began, and the situation was not helped when Colby did not credit Weizenbaum for his contribution to the program. In 1976, Weizenbaum published Computer Power and Human Reason which argued that the misuse of artificial intelligence has the potential to devalue human life.\n\nPerceptrons and the attack on connectionism\nA perceptron was a form of neural network introduced in 1958 by Frank Rosenblatt, who had been a schoolmate of Marvin Minsky at the Bronx High School of Science. Like most AI researchers, he was optimistic about their power, predicting that \"perceptron may eventually be able to learn, make decisions, and translate languages.\" An active research program into the paradigm was carried out throughout the 1960s but came to a sudden halt with the publication of Minsky and Papert's 1969 book Perceptrons. It suggested that there were severe limitations to what perceptrons could do and that Frank Rosenblatt's predictions had been grossly exaggerated. The effect of the book was devastating: virtually no research at all was done in connectionism for 10 years. Eventually, a new generation of researchers would revive the field and thereafter it would become a vital and useful part of artificial intelligence. Rosenblatt would not live to see this, as he died in a boating accident shortly after the book was published.\n\nLogic and symbolic reasoning: the \"neats\"\nLogic was introduced into AI research as early as 1959, by John McCarthy in his Advice Taker proposal. In 1963, J. Alan Robinson had discovered a simple method to implement deduction on computers, the resolution and unification algorithm. However, straightforward implementations, like those attempted by McCarthy and his students in the late 1960s, were especially intractable: the programs required astronomical numbers of steps to prove simple theorems. A more fruitful approach to logic was developed in the 1970s by Robert Kowalski at the University of Edinburgh, and soon this led to the collaboration with French researchers Alain Colmerauer and Philippe Roussel who created the successful logic programming language Prolog. Prolog uses a subset of logic (Horn clauses, closely related to \"rules\" and \"production rules\") that permit tractable computation. Rules would continue to be influential, providing a foundation for Edward Feigenbaum's expert systems and the continuing work by Allen Newell and Herbert A. Simon that would lead to Soar and their unified theories of cognition.\n\nCritics of the logical approach noted, as Dreyfus had, that human beings rarely used logic when they solved problems. Experiments by psychologists like Peter Wason, Eleanor Rosch, Amos Tversky, Daniel Kahneman and others provided proof. McCarthy responded that what people do is irrelevant. He argued that what is really needed are machines that can solve problems—not machines that think as people do.\n\nFrames and scripts: the \"scuffles\"\nAmong the critics of McCarthy's approach were his colleagues across the country at MIT. Marvin Minsky, Seymour Papert and Roger Schank were trying to solve problems like \"story understanding\" and \"object recognition\" that required a machine to think like a person. In order to use ordinary concepts like \"chair\" or \"restaurant\" they had to make all the same illogical assumptions that people normally made. Unfortunately, imprecise concepts like these are hard to represent in logic. Gerald Sussman observed that \"using precise language to describe essentially imprecise concepts doesn't make them any more precise.\" Schank described their \"anti-logic\" approaches as \"scruffy\", as opposed to the \"neat\" paradigms used by McCarthy, Kowalski, Feigenbaum, Newell and Simon.\n\nIn 1975, in a seminal paper, Minsky noted that many of his fellow \"scruffy\" researchers were using the same kind of tool: a framework that captures all our common sense assumptions about something. For example, if we use the concept of a bird, there is a constellation of facts that immediately come to mind: we might assume that it flies, eats worms and so on. We know these facts are not always true and that deductions using these facts will not be \"logical\", but these structured sets of assumptions are part of the context of everything we say and think. He called these structures \"frames\". Schank used a version of frames he called \"scripts\" to successfully answer questions about short stories in English.",

        "evidence": "End-to-end speech-to-text translation (ST) has attracted much attention recently BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6 given its simplicity against cascading automatic speech recognition (ASR) and machine translation (MT) systems. The lack of labeled data, however, has become a major blocker for bridging the performance gaps between end-to-end models and cascading systems. Several corpora have been developed in recent years. post2013improved introduced a 38-hour Spanish-English ST corpus by augmenting the transcripts of the Fisher and Callhome corpora with English translations. di-gangi-etal-2019-must created the largest ST corpus to date from TED talks but the language pairs involved are out of English only. beilharz2019librivoxdeen created a 110-hour German-English ST corpus from LibriVox audiobooks. godard-etal-2018-low created a Moboshi-French ST corpus as part of a rare language documentation effort. woldeyohannis provided an Amharic-English ST corpus in the tourism domain. boito2019mass created a multilingual ST corpus involving 8 languages from a multilingual speech corpus based on Bible readings BIBREF7. Previous work either involves language pairs out of English, very specific domains, very low resource languages or a limited set of language pairs. This limits the scope of study, including the latest explorations on end-to-end multilingual ST BIBREF8, BIBREF9. Our work is mostly similar and concurrent to iranzosnchez2019europarlst who created a multilingual ST corpus from the European Parliament proceedings. The corpus we introduce has larger speech durations and more translation tokens. It is diversified with multiple speakers per transcript/translation. Finally, we provide additional out-of-domain test sets.\nIn this paper, we introduce CoVoST, a multilingual ST corpus based on Common Voice BIBREF10 for 11 languages into English, diversified with over 11,000 speakers and over 60 accents. It includes a total 708 hours of French (Fr), German (De), Dutch (Nl), Russian (Ru), Spanish (Es), Italian (It), Turkish (Tr), Persian (Fa), Swedish (Sv), Mongolian (Mn) and Chinese (Zh) speeches, with French and German ones having the largest durations among existing public corpora. We also collect an additional evaluation corpus from Tatoeba for French, German, Dutch, Russian and Spanish, resulting in a total of 9.3 hours of speech. Both corpora are created at the sentence level and do not require additional alignments or segmentation. Using the official Common Voice train-development-test split, we also provide baseline models, including, to our knowledge, the first end-to-end many-to-one multilingual ST models. CoVoST is released under CC0 license and free to use. The Tatoeba evaluation samples are also available under friendly CC licenses.

In our experiments, the RNN takes in spectrograms of utterances, passing them through two 2D-convolutional layers, followed by seven bi-directional recurrent layers and a fully-connected layer with softmax activation. All recurrent layers are batch normalized. At each timestep, the softmax activations give a probability distribution over the characters. CTC loss BIBREF8 is then computed from the timestep-wise probabilities.\nA base model, INLINEFORM0 , is trained on 190 hours ( INLINEFORM1 100K instances) of transcribed speech data. Then, it selects a subset of a 1,700-hour ( INLINEFORM2 1.1M instances) unlabeled dataset. We query labels for the selected subset and incorporate them into training. Learning rates are tuned on a small validation set of 2048 instances. The trained model is then tested on a 156-hour ( INLINEFORM3 100K instances) test set and we report CTC loss, Character Error Rate (CER) and Word Error Rate (WER).\nThe confidence score methods BIBREF1 , BIBREF2 can be easily extended to our setup. Specifically, from the probabilities over the characters, we can compute an entropy per timestep and then average them. This method is denoted as entropy. We could also take the most likely prediction and calculate its CTC loss, normalized by number of timesteps. This method is denoted as pCTC (predicted CTC) in the following sections.\nWe implement EGL by marginalizing over the most likely 100 labels, and compare it with: 1) a random selection baseline, 2) entropy, and 3) pCTC. Using the same base model, each method queries a variable percentage of the unlabeled dataset. The queries are then included into training set, and the model continues training until convergence. Fig. FIGREF9 reports the metrics (Exact values are reported in Table TABREF12 in the Appendix) on the test set as the query percentage varies. All the active learning methods outperform the random baseline. Moreover, EGL shows a steeper, more rapid reduction in error than all other approaches. Specifically, when querying 20% of the unlabeled dataset, EGL has 11.58% lower CER and 11.09% lower WER relative to random. The performance of EGL at querying 20% is on par with random at 40%, suggesting that using EGL can lead to an approximate 50% decrease in data labeling.\nWe implement EGL by marginalizing over the most likely 100 labels, and compare it with: 1) a random selection baseline, 2) entropy, and 3) pCTC.",

        "question": "Why is at an Adjustment gate？",
        "answer": "Because its task is to control what information of the given DA have been generated and what information should be retained for future time steps.",
        "evidence": "The proposed semantic RALSTM cell applied for Decoder side consists of three components: a Refinement cell, a traditional LSTM cell, and an Adjustment cell:\nFirstly, instead of feeding the original input token $\\textbf {w}_{t}$ into the RNN cell, the input is recomputed by using a semantic gate as follows: \n$$\\begin{aligned}\n\\textbf {r}_{t}&=\\sigma (\\textbf {W}_{rd}\\textbf {d}_{t} + \\textbf {W}_{rh}\\textbf {h}_{t-1})\\\\\n\\textbf {x}_{t}&=\\textbf {r}_{t} \\odot \\textbf {w}_{t}\n\\end{aligned}$$   (Eq. 19) \nwhere $\\textbf {W}_{rd}$ and $\\textbf {W}_{rh}$ are weight matrices. Element-wise multiplication $\\odot $ plays a part in word-level matching which not only learns the vector similarity, but also preserves information about the two vectors. $\\textbf {W}_{rh}$ acts like a key phrase detector that learns to capture the pattern of generation tokens or the relationship between multiple tokens. In other words, the new input $\\textbf {x}_{t}$ consists of information of the original input token $\\textbf {w}_{t}$ , the DA representation $\\textbf {d}_{t}$ , and the hidden context $\\textbf {h}_{t-1}$ . $\\textbf {r}_{t}$ is called a Refinement gate because the input tokens are refined by a combination gating information of the attentive DA representation $\\textbf {d}_{t}$ and the previous hidden state $\\textbf {W}_{rh}$0 . By this way, we can represent the whole sentence based on the refined inputs.\nSecondly, the traditional LSTM network proposed by BIBREF26 bahdanau2014neural in which the input gate $\\textbf {i}_{i}$ , forget gate $\\textbf {f}_{t}$ and output gates $\\textbf {o}_{t}$ are introduced to control information flow and computed as follows: \n$$\\begin{aligned}\n\\begin{pmatrix}\n\\textbf {i}_{t}\n\\\\ \\textbf {f}_{t}\n\\\\ \\textbf {o}_{t}\n\\\\ \\hat{\\textbf {c}}_{t}\n\\end{pmatrix}\n&=\n\\begin{pmatrix}\\sigma \\\\ \\sigma \\\\ \\sigma \\\\ \\tanh \\end{pmatrix}\\textbf {W}_{4n,4n}\n\\begin{pmatrix}\n\\textbf {x}_{t}\n\\\\ \\textbf {d}_{t}\n\\\\ \\textbf {h}_{t-1}\n\\end{pmatrix}\\\\\n\\end{aligned}$$   (Eq. 20) \nwhere $n$ is hidden layer size, $\\textbf {W}_{4n,4n}$ is model parameters. The cell memory value $\\textbf {c}_{t}$ is modified to depend on the DA representation as: \n$$\\begin{aligned}\n\\textbf {c}_{t}&=\\textbf {f}_{t}\\odot \\textbf {c}_{t-1} +\\textbf {i}_{t}\\odot \\hat{\\textbf {c}}_{t} + \\tanh (\\textbf {W}_{cr}\\textbf {r}_{t})\n\\\\ \\tilde{\\textbf {h}}_{t}&= \\textbf {o}_{t} \\odot \\tanh (\\textbf {c}_{t})\n\\end{aligned}$$   (Eq. 21) \nwhere $\\tilde{\\textbf {h}}_{t}$ is the output.\nThirdly, inspired by work of BIBREF4 in which the generator was further conditioned on a 1-hot representation vector $\\textbf {s}$ of given dialogue act, and work of BIBREF27 that proposed a visual sentinel gate to make a decision on whether the model should attend to the image or to the sentinel gate, an additional gating cell is introduced on top of the traditional LSTM to gate another controlling vector $\\textbf {s}$ . Figure 6 shows how RALSTM controls the DA vector $\\textbf {s}$ . First, starting from the 1-hot vector of the DA $\\textbf {s}_{0}$ , at each time step $t$ the proposed cell computes how much the LSTM output $\\tilde{\\textbf {h}}_{t}$ affects the DA vector, which is computed as follows: \n$$\\begin{aligned}\n\\textbf {a}_{t}&=\\sigma (\\textbf {W}_{ax}\\textbf {x}_{t} +\\textbf {W}_{ah}\\tilde{\\textbf {h}}_{t})\\\\\n\\textbf {s}_{t}&=\\textbf {s}_{t-1} \\odot \\textbf {a}_{t}\n\\end{aligned}$$   (Eq. 22) \nwhere $\\textbf {W}_{ax}$ , $\\textbf {W}_{ah}$ are weight matrices to be learned. $\\textbf {a}_{t}$ is called an $Adjustment$ gate since its task is to control what information of the given DA have been generated and what information should be retained for future time steps. Second, we consider how much the information preserved in the DA $\\textbf {s}_{t}$ can be contributed to the output, in which an additional output is computed by applying the output gate $\\textbf {o}_{t}$ on the remaining information in $\\textbf {s}_{t}$ as follows: \n$$\\begin{aligned}\n\\textbf {c}_{a}&=\\sigma (\\textbf {W}_{os}\\textbf {s}_{t})\\\\\n\\tilde{\\textbf {h}}_{a}&= \\textbf {o}_{t} \\odot \\tanh (\\textbf {c}_{a})\n\\end{aligned}$$   (Eq. 23) \nwhere $\\textbf {W}_{os}$ is a weight matrix to project the DA presentation into the output space, $\\tilde{\\textbf {h}}_{a}$ is the Adjustment cell output. Final RALSTM output is a combination of both outputs of the traditional LSTM cell and the Adjustment cell, and computed as follows: \n$$\\textbf {h}_{t}=\\tilde{\\textbf {h}}_{t} + \\tilde{\\textbf {h}}_{a}$$   (Eq. 24) \nFinally, the output distribution is computed by applying a softmax function $g$ , and the distribution can be sampled to obtain the next token, \n$$\\begin{aligned}\n& P(w_{t+1}\\mid w_{t},...w_{0},\\textbf {DA})=g(\\textbf {W}_{ho}\\textbf {h}_{t}) \\\\\n& w_{t+1} \\sim P(w_{t+1}\\mid w_{t}, w_{t-1},...w_{0},\\textbf {DA})\n\\end{aligned}$$   (Eq. 25) \nwhere $\\textbf {DA}=(\\textbf {s}, \\textbf {z})$ .\nat is called an Adjustment gate since its task is to control what information of the given DA have been generated and what information should be retained for future time steps.",

We did not tune the Hebbian networks’ hyper-parameters extensively, so accuracies on these tasks are not definitive but do give a good indication. On F-MNIST, the SoftHebb model achieved a top accuracy of 87.46% whereas a hard WTA reached a similar accuracy of 87.49%. A supervised MLP of the same size achieved a test accuracy of 90.55%. SoftHebb’s generative interpolations (Fig. 3B) are reconfirmed on the F-MNIST dataset, as is its robustness to attacks, whereas, with very small adversarial perturbations, the MLP drops to an accuracy lower than the SoftHebb model (dashed lines in Fig. 2). On CIFAR-10’s preliminary results, the hard WTA and SoftHebb achieved an accuracy of 49.78% and 50.27% respectively. In every tested dataset, it became clear that SoftHebb learns faster than either backpropagation or a hard WTA, by observing the loss and the learned features as in Fig. 1 C & D. The fully-connected SoftHebb layer is applicable on MNIST because the data classes are well-clustered directly in the feature-space of pixels. That is, SoftHebb’s probabilistic model’s assumptions (Def. 2.1) are quite valid for this feature space, and increasing the number of neurons for discovering more refined sub-clusters does help. However, for more complex datasets, this approach alone has diminishing returns and multilayer networks will be needed. Towards this, we implemented a first version of a convolutional SoftHebb, with an added supervised classifier. In these early results, conv-SoftHebb achieved 98.63% on MNIST, and 60.30% on CIFAR-10. This confirms that conv-SoftHebb is functional, but we did not systematically optimize its accuracy or explore its other strengths. This feasibility is evidence that SoftHebb’s strengths may soon also apply to larger networks and datasets.",

        "evidence": "We experimented with four DNN based models for cyberbullying detection: CNN, LSTM, BLSTM, and BLSTM with attention. These models are listed in the increasing complexity of their neural architecture and amount of information used by these models. Please refer to Figure 1 for general architecture that we have used across four models. Various models differ only in the Neural Architecture layer while having identical rest of the layers. CNNs are providing state-of-the-results on extracting contextual feature for classification tasks in images, videos, audios, and text. Recently, CNNs were used for sentiment classification BIBREF9 . Long Short Term Memory networks are a special kind of RNN, capable of learning long-term dependencies. Their ability to use their internal memory to process arbitrary sequences of inputs has been found to be effective for text classification BIBREF10 . Bidirectional LSTMs BIBREF11 further increase the amount of input information available to the network by encoding information in both forward and backward direction. By using two directions, input information from both the past and future of the current time frame can be used. Attention mechanisms allow for a more direct dependence between the state of the model at different points in time. Importantly, attention mechanism lets the model learn what to attend to based on the input sentence and what it has produced so far.\nThe embedding layer processes a fixed size sequence of words. Each word is represented as a real-valued vector, also known as word embeddings. We have experimented with three methods for initializing word embeddings: random, GloVe BIBREF12 , and SSWE BIBREF13 . During the training, model improves upon the initial word embeddings to learn task specific word embeddings. We have observed that these task specific word embeddings capture the SMP specific and topic specific style of cyberbullying. Using GloVe vectors over random vector initialization has been reported to improve performance for some NLP tasks. Most of the word embedding methods such as GloVe, consider only syntactic context of the word while ignoring the sentiment conveyed by the text. SSWE method overcomes this problem by incorporating the text sentiment as one of the parameters for word embedding generation. We experimented with various dimension size for word embeddings. Experimental results reported here are with dimension size as 50. There was no significant variation in results with dimension size ranging from 30 to 200.\nTo avoid overfitting, we used two dropout layers, one before the neural architecture layer and one after, with dropout rates of 0.25 and 0.5 respectively. Fully connected layer is a dense output layer with the number of neurons equal to the number of classes, followed by softmax layer that provides softmax activation. All our models are trained using backpropagation. The optimizer used for training is Adam and the loss function is categorical cross-entropy. Besides learning the network weights, these methods also learn task-specific word embeddings tuned towards the bullying labels (See Section SECREF21 ).

        "question": "Is there any way to test the claim of \"negative transfer\" in 4.2? Often, when streaming suffers this \"negative transfer\", JT does not seem to, even with the same chunks.",
        "answer": "Based on your suggestions, we provide more empirical evidence to describe and explain the existence of “negative transfer”. We observe severe “negative transfer'' when pre-training models with distant class incremental sequence and evaluating them on Oxford-IIIT Pets. The “negative transfer” exists in two forms (1) ST models may outperform JT models. (2) The model performance may drop with the increase of chunk number for both ST and JT models. To be specific, on the 4-chunk streaming data, at step 2, we find models sequentially trained by the second data chunk show good performance on the testing data of Pets, for both many-shot and few-shot evaluation. In contrast, when the model is sequentially trained by other data chunks, i.e. step 3 and step4, more data for training instead leads to significant performance degradation for sequential training, and visible performance reduction for joint training. We find the reason is that only the second data chunk has lots of similar classes to the Pets dataset.\nThe reason that JT models suffer less “negative transfer” is that JT models can access previous data chunks, except for the current irrelevant chunks. For example, in the sequential learning of D-A-B-C, when training with the B chunk, JT models can have D, A, and B chunks for training. The relevant data in chunk A can significantly mitigate the “negative transfer” brought by data in chunk D and B. However, with only data in chunk B, ST models cannot avoid the severe “negative transfer”. See Section 4.2 and Appendix B.3 for more details of “negative transfer”.\n\n",
        "evidence": "In pre-training tasks, we pay attention to the generalization of the learned representations to new data or tasks rather than the performance on the training dataset. Taking a closer look at the results in Figures, we observe that, although joint SSL models achieve comparable performance to joint SL models in linear evaluation, joint SL models significantly outperform joint SSL models in few-shot evaluation. This observation is also demonstrated in. The main difference between the two evaluation protocols is that linear evaluation involves more fine-tuning than few-shot evaluation, as introduced in Appendix A.4. Therefore, the underlying reason for the observation is that supervised features are correlated with labels and more discriminative, thus easy to directly transfer to downstream datasets similar to upstream pre-training data (DomainNet or ImageNet). For example, SL models dominate most few-shot object or scene classification tasks but fail on DTD, a texture classification dataset sharing no common classes with ImageNet or DomainNet. In contrast, self-supervised features are more generalized and comprehensive, thus requiring more fine-tuning for desirable downstream transfer. In addition, on some downstream datasets, we have seemingly abnormal observations that ST models may outperform JT models and the model performance may drop with the increase of chunk number. These phenomena are due to the so-called \"negative transfer\", which is also discussed in other model pre-training studies. That is, pre-training with more data chunks does not necessarily benefit a specific downstream dataset if the added training data are irrelevant to the downstream dataset. See Appendix B.3 for a concrete example of \"negative transfer\" on Oxford-IIIT Pets in pre-training with streaming data. It is observed that sequential SSL models suffer less \"negative transfer\" than SL models and continual learning methods largely prevent \"negative transfer\".\nThese phenomena are due to the so-called “negative transfer” (Wang et al., 2019), which is also discussed in other model pre-training studies (Newell & Deng, 2020; Gururangan et al., 2020). That is, pre-training with more data chunks does not necessarily benefit a specific downstream dataset if the added training data are irrelevant to the downstream dataset. See Appendix B.3 for a concrete example of “negative transfer” on Oxford-IIIT Pets (Parkhi et al., 2012) in pre-training with streaming data.****We observe severe “negative transfer” when pre-training models with distant class incremental sequence and evaluating them on Oxford-IIIT Pets (Parkhi et al., 2012). Specifically, as shown in Figure 12, SSL-ST slightly outperforms SSL-JT at the second chunk, i.e., chunk A. After chunk A,increasing more chunks for SSL-JT models, i.e., chunk B and chunk C, instead leads to significant decrease in performance. We make careful comparison between images from chunk A and images in Pets. We find that Oxford-IIIT Pets includes 37 categories of pets like dogs and cats. As mentioned in Appendix A.1, Chunk A includes many relevant classes like ‘Maltese dog’, ‘Old English sheepdog’, ‘Shetland sheepdog’, ‘Greater Swiss Mountain dog’, ‘Bernese mountain dog’, ‘French bulldog’, ‘Eskimo dog’, ‘African hunting dog’, ‘tabby’, ‘tiger cat’, ‘Persian cat’, ‘Siamese cat’, ‘Egyptian cat’, and ‘Madagascar cat’. The other three data chunks, i.e., chunk D, B, and C, do not have these classes. Such observations are consistent with the widely accepted belief that “transferring knowledge from the dissimilar source can have a negative impact on the target learner” (Wang et al., 2019). Note that SL models suffer severer ‘negative transfer’ than SSL models and continual learning methods can help SSL models significantly reduce the negative transfer, achieving on-par performance to SSL-JT models.",

        "evidence": "The challenges of imbalanced classification—in which the proportion of elements in each class for a classification task significantly differ—and of the ability to generalise on dissimilar data have remained important problems in Natural Language Processing (NLP) and Machine Learning in general. Popular NLP tasks including sentiment analysis, propaganda detection, and event extraction from social media are all examples of imbalanced classification problems. In each case the number of elements in one of the classes (e.g. negative sentiment, propagandistic content, or specific events discussed on social media, respectively) is significantly lower than the number of elements in the other classes.\nThe recently introduced BERT language model for transfer learning BIBREF0 uses a deep bidirectional transformer architecture to produce pre-trained context-dependent embeddings. It has proven to be powerful in solving many NLP tasks and, as we find, also appears to handle imbalanced classification well, thus removing the need to use standard methods of data augmentation to mitigate this problem (see Section SECREF11 for related work and Section SECREF16 for analysis).\nBERT is credited with the ability to adapt to many tasks and data with very little training BIBREF0. However, we show that BERT fails to perform well when the training and test data are significantly dissimilar, as is the case with several tasks that deal with social and news data. In these cases, the training data is necessarily a subset of past data, while the model is likely to be used on future data which deals with different topics. This work addresses this problem by incorporating cost-sensitivity (Section SECREF19) into BERT.\nWe test these methods by participating in the Shared Task on Fine-Grained Propaganda Detection for the 2nd Workshop on NLP for Internet Freedom, for which we achieve the second rank on sentence-level classification of propaganda, confirming the importance of cost-sensitivity when the training and test sets are dissimilar.\nHowever, we show that BERT fails to perform well when the training and test data are significantly dissimilar, as is the case with several tasks that deal with social and news data.

Crucially, the tweets in both languages focus on the same issue (Catalan independence); given this fact they are the first truly multilingual stance detection datasets known to us.\nWith regard to the languages covered by x-stance, only monolingual datasets seem to be available. For French, a collection of tweets on French presidential candidates has been annotated with stance BIBREF6. Similarly, two datasets of Italian tweets on the occasion of the 2016 constitutional referendum have been created BIBREF7, BIBREF6. For German, there is no known stance detection dataset, but an aspect-based sentiment dataset has been created for a GermEval 2017 shared task BIBREF8.\nThe SemEval-2016 task on detecting stance in tweets BIBREF9 offers data concerning multiple targets (Atheism, Climate Change, Feminism, Hillary Clinton, and Abortion). In the supervised subtask A, participants tended to develop a target-specific model for each of those targets. In subtask B cross-target transfer to the target “Donald Trump” was tested, for which no annotated training data were provided. While this required the development of more universal models, their performance was generally much lower.\nBIBREF4 introduced a multi-target stance dataset which provides two targets per instance. For example, a model designed in this framework is supposed to simultaneously classify a tweet with regard to Clinton and with regard to Trump. While in theory the framework allows for more than two targets, it is still restricted to a finite and clearly defined set of targets. It focuses on modeling the dependencies of multiple targets within the same text sample, while our approach focuses on learning stance detection from many samples with many different targets.\nIn a target-specific setting, BIBREF10 perform a systematic evaluation of stance detection approaches. They also evaluate Bert BIBREF5 and find that it consistently outperforms previous approaches.\nHowever, they only experimented with a single-segment encoding of the input, preventing cross-target transfer of the model. BIBREF11 propose a conditional encoding approach to encode both the target and the tweet as sequences. They use a bidirectional LSTM to condition the encoding of the tweets on the encoding of the target, and then apply a nonlinear projection on the conditionally encoded tweet. This allows them to train a model that can generalize to previously unseen targets.\nIn the context of the IberEval shared tasks, two related multilingual datasets have been created (Taulé et al., 2017, 2018).

Due to non-convexity, it is hard to systematically or exhaustively search a continuous and high dimensional input space, so even given an attack a very long time (e.g., run PGD attack for 10,000 iterations or 10,000 random start points), it can still miss some adversarial examples.\nWe formulate the attack in the activation space, by encoding the ReLU neurons as 0-1 variables in a mixed integer programming (MIP) formulation. The problem is discrete so we can systematically search it via branch and bound and find more adversarial examples. MIP based attacks are often stronger than other attacks. Given an infinite amount of time, it can guarantee to find an adversarial example if one exists thanks to the systematic search procedure.",
        "evidence": "Adversarial attacks aim to find adversarial examples, which are close to benign inputs in certain distance metrics yet trigger wrong behavior of neural networks. Adversarial attacks are important tools to gauge the empirical robustness of deep neural networks. Finding an adversarial example can be generally formulated as a constrained optimization problem:\nwhere C is often an ∞ or 2 norm ball around the original input x 0 , and f (x) is an attack success criterion involving a neural network (such as the margin between the groundtruth class and another class): f (x) < 0 indicates a successful attack. A straightforward way of solving Eq. () is via firstorder constrained optimization methods, such as projected gradient descent (PGD) and its variants. Additionally, some gradient-free attacks were proposed, mostly based on certain heuristic search on the input space x.\nLimitations of existing attacks. As f (x) usually consists of a highly non-convex neural network, solving Eq. () to its global minimum is challenging. This leads to failures in adversarial attacks: an adversarial example may exist but no attacks can find it, giving a false sense of security. Especially, gradient based attacks can be easily trapped into a local minimum or misguided by masked gradients. Even if we give the attacker an infinite amount of time (e.g., run a very large number of PGD steps, or allowing a large number of samples on input space), it is still hard to guarantee to find the adversarial example, since it is extremely difficult to systematically search the high dimensional and continuous input space. Models concluded robust under existing attacks might still have security vulnerability in practice, leading to an urgent request for stronger attacks that can possibly approach ground-truth robustness.\nThe mixed-integer approach. This paper seeks stronger adversarial attacks from a different angle: instead of searching for adversarial examples in the input space, we look for adversarial examples in the activation space. The main intuition is that neural networks with piece-wise linear activation functions (e.g., ReLU) can be seen as a piece-wise linear function and each piece is uniquely defined by a specific setting of activation function status. For ReLU networks, each neuron can either be active (its input is positive) or inactive (its input is negative so the output is 0), which can be encoded by discrete 0-1 variables. This leads to a mixed integer programming (MIP) formulation, and  conducted attacks using a MIP solver.\nBenefits of the MIP formulation. The MIP formulation with the 0-1 encoding of ReLU neurons allows us to systematically search all the linear pieces in the input space, theoretically guarantee to enumerate the entire input space and obtain the global minimum of Eq. () given sufficient time.\nPractically, MIP-based attacks can often find adversarial examples that are missed by existing attacks and identify true weaknesses of a model. It also helps to close the gap between the upper and lower bounds of robust accuracy (i.e., attack accuracy vs. verified accuracy). Existing works aimed to reducing this gap by tightening the lower bound with stronger verifiers, while our work aims to tighten the upper bound by a systematic search of adversarial examples. Closing this gap is difficult even on small models.\nGeneric MIP solvers are inefficient for adversarial attacks. Despite its strengths, a MIP-based attack are often a few orders of magnitudes slower than existing attacks due to the high cost of running an off-the-shelf solver such as Gurobi . There are three root causes for its inefficiency. First, an off-the-shelf solver is not aware of the underlying optimization problem corresponds to a neural network, and has to apply generic solving techniques (e.g., using Simplex algorithm with relaxations) which can be expensive or ineffective. Second, it cannot utilize solutions obtained cheaply from gradient based attacks to accelerate its search. Third, generic MIP solvers are mostly restricted to CPUs and can hardly utilize GPU acceleration, which is crucial for efficiency.\nContributions of this paper. We address the above weaknesses in MIP solvers for adversarial attacks, by developing a GPU-accelerated branch and bound procedure to systematically search adversarial examples in the activation space, which is more efficient than generic MIP solvers. We focus on solving hard instances, where none of existing adversarial attacks based on searching the input space are successful but no verifier can prove their robustness. Our contributions includes:\n• We apply the GPU-accelerated bound propagation based methods, which were originally developed for neural network verification, to the adversarial attack setting. These specialized methods can quickly examine thousands of regions in activation space in parallel and rule out the regions with no adversarial examples, which is difficult in off-the-shelf MIP solvers with a generic solving procedure.\n• We employ a top-down beam-search to explore the activation space. • Our new attack framework, BaB-Attack, is designed to tackle hard instances where existing strong adversarial attacks (such as AutoAttack) cannot succeed. Despite being more expensive than attacks on the input space, BaB-Attack is about an order of magnitude faster than using an MIP solver on hard instances, and can find adversarial examples that cannot be discovered by any existing attacks.\nBenefits of the MIP formulation. The MIP formulation with the 0-1 encoding of ReLU neurons allows us to systematically search all the linear pieces in the input space, theoretically guarantee to enumerate the entire input space and obtain the global minimum of Eq. (1) given sufficient time. Practically, MIP-based attacks can often find adversarial examples that are missed by existing attacks and identify true weaknesses of a model. It also helps to close the gap between the upper and lower bounds of robust accuracy (i.e., attack accuracy vs. verified accuracy). Existing works aimed to reducing this gap by tightening the lower bound with stronger verifiers (Raghunathan et al., 2018b; Wang et al., 2021), while our work aims to tighten the upper bound by a systematic search of adversarial examples. Closing this gap is difficult even on small models (Dathathri et al., 2020).\nGeneric MIP solvers are inefficient for adversarial attacks. Despite its strengths, a MIP-based attack are often a few orders of magnitudes slower than existing attacks due to the high cost of running an off-the-shelf solver such as Gurobi (Tjeng et al., 2019). There are three root causes for its inefficiency. First, an off-the-shelf solver is not adware of the underlying optimization problem corresponds to a neural network, and has to apply generic solving techniques (e.g., using Simplex algorithm with relaxations) which can be expensive or ineffective. Second, it cannot utilize solutions obtained cheaplyfrom gradient based attacks to accelerate its search. Third, generic MIP solvers are mostly restricted to CPUs and can hardly utilize GPU acceleration, which is crucial for efficiency.",

        "evidence": "The Flickr30K dataset BIBREF0 is a collection of over 30,000 images with 5 crowdsourced descriptions each. It is commonly used to train and evaluate neural network models that generate image descriptions (e.g. BIBREF2 ). An untested assumption behind the dataset is that the descriptions are based on the images, and nothing else. Here are the authors (about the Flickr8K dataset, a subset of Flickr30K):\n“By asking people to describe the people, objects, scenes and activities that are shown in a picture without giving them any further information about the context in which the picture was taken, we were able to obtain conceptual descriptions that focus only on the information that can be obtained from the image alone.” BIBREF1 \nWhat this assumption overlooks is the amount of interpretation or recontextualization carried out by the annotators. Let us take a concrete example. Figure FIGREF1 shows an image from the Flickr30K dataset.\nThis image comes with the five descriptions below. All but the first one contain information that cannot come from the image alone. Relevant parts are highlighted in bold:\nWe need to understand that the descriptions in the Flickr30K dataset are subjective descriptions of events. This can be a good thing: the descriptions tell us what are the salient parts of each image to the average human annotator. So the two humans in Figure FIGREF1 are relevant, but the two soap dispensers are not. But subjectivity can also result in stereotypical descriptions, in this case suggesting that the male is more likely to be the manager, and the female is more likely to be the subordinate. rashtchian2010collecting do note that some descriptions are speculative in nature, which they say hurts the accuracy and the consistency of the descriptions. But the problem is not with the lack of consistency here. Quite the contrary: the problem is that stereotypes may be pervasive enough for the data to be consistently biased. And so language models trained on this data may propagate harmful stereotypes, such as the idea that women are less suited for leadership positions.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices. I will build on earlier work on linguistic bias in general BIBREF3 , providing examples from the Flickr30K data, and present a taxonomy of unwarranted inferences.

        "answer": "Yes, this is.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nTo the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings.",

We disentangled different types of interactions on Twitter to accordingly build a multi-layer representation of news diffusion networks, and we computed a set of global network properties–separately for each layer–in order to encode each network with a tuple of features. Our goal was to investigate whether a multi-layer representation performs better than one layer BIBREF11, and to understand which of the features, observed at given layers, are most effective in the classification task.\nExperiments with an off-the-shelf classifier such as Logistic Regression on datasets pertaining to two different media landscapes (US and Italy) yield very accurate classification results (AUROC up to 94%), even when accounting for the different political bias of news sources, which are far better than our baseline BIBREF11 with improvements up to 20%. Classification performances using single layers show that the layer of mentions alone entails better performance w.r.t other layers in both countries.\nWe also highlighted the most discriminative features across different layers in both countries; the results suggest that differences between the two news domains might be country-independent but rather due only to the typology of content shared, and that disinformation news shape broader and deeper cascades.\nAdditional experiments involving the temporal evolution of Twitter diffusion networks show that our methodology can accurate classify mainstream and disinformation news after a few hours of propagation on the platform.\nOverall, our results prove that the topological features of multi-layer diffusion networks might be effectively exploited to detect online disinformation. We do not deny the presence of deceptive efforts to orchestrate the regular spread of information on social media via content amplification and manipulation BIBREF37BIBREF38. On the contrary, we postulate that such hidden forces might play to accentuate the discrepancies between the diffusion patterns of disinformation and mainstream news (and thus to make our methodology effective).\nIn the future we aim to further investigate three directions: (1) employ temporal networks to represent news diffusion and apply classification techniques that take into account the sequential aspect of data (e.g. recurrent neural networks); (2) carry out an extensive comparison of the diffusion of disinformation and mainstream news across countries to investigate deeper the presence of differences and similarities in sharing patterns; (3) leverage our network-based features in addition to state-of-the-art text-based approaches for \"fake news\" dete ction in order to deliver a real-world system to detect misleading and harmful information spreading on social media.\nIn this work we tackled the problem of the automatic classification of news articles in two domains, namely mainstream and disinformation news, with a language-independent approach which is based solely on the diffusion of news items on Twitter social platform.",

This dataset was built from two different sources, for the trusted news (real news) they sampled news articles from the English Gigaword corpus. For the false news, they collected articles from seven different unreliable news sites. These news articles include satires, hoaxes, and propagandas but not clickbaits. Since we are interested also in analyzing clickbaits, we slice a sample from an available clickbait dataset BIBREF33 that was originally collected from two sources: Wikinews articles' headlines and other online sites that are known to publish clickbaits. The satire, hoax, and propaganda news articles are considerably long (some of them reach the length of 5,000 words). This length could affect the quality of the analysis as we mentioned before. We focus on analyzing the initial part of the article. Our intuition is that it is where emotion-bearing words will be more frequent. Therefore, we shorten long news articles into a maximum length of N words (N=300). We choose the value of N based on the length of the shortest articles. Moreover, we process the dataset by removing very short articles, redundant articles or articles that do not have a textual content.\nWith the complicated political and economic situations in many countries, some agendas are publishing suspicious news to affect public opinions regarding specific issues BIBREF0. The spreading of this phenomenon is increasing recently with the large usage of social media and online news sources. Many anonymous accounts in social media platforms start to appear, as well as new online news agencies without presenting a clear identity of the owner. Twitter has recently detected a campaign organized by agencies from two different countries to affect the results of the last U.S. presidential elections of 2016. The initial disclosures by Twitter have included 3,841 accounts. A similar attempt was done by Facebook, as they detected coordinated efforts to influence U.S. politics ahead of the 2018 midterm elections.\nFor this dataset, we rely on a list of several Twitter accounts for each type of false information from BIBREF6. This list was created based on public resources that annotated suspicious Twitter accounts. The authors in BIBREF6 have built a dataset by collecting tweets from these accounts and they made it available. For the real news, we merge this list with another 32 Twitter accounts from BIBREF34. In this work we could not use the previous dataset and we decide to collect tweets again. For each of these accounts, we collected the last M tweets posted (M=1000). By investigating these accounts manually, we found that many tweets just contain links without textual news. Therefore, to ensure of the quality of the crawled data, we chose a high value for M (also to have enough data).

How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously.",

        "evidence": "The masked language modeling (MLM) BIBREF13 task, also known as the Cloze task BIBREF23, aims at predicting the randomly masked words according to their context. The objective pretrains the bidirectional encoder to obtain contextual representations. Following BIBREF13, we randomly mask 15% of the tokens in a monolingual sentence. For each masked token, we substitute it with a special token M, a random token, or the unchanged token with a probability of 0.8, 0.1, and 0.1, respectively. Let $x$ denote a sentence from the monolingual training corpus, and $M_{x}$ the set of randomly masked positions. The monolingual MLM loss is defined as: MLM(x) = -i Mxp( xi | xMx) where $x_{\\setminus M_{x}}$ is the masked version of input $x$. Notice that language tags are fed into the model for all pre-training tasks.\nWe use the denoising auto-encoding (DAE) objective BIBREF24 to pretrain the encoder-decoder attention mechanism. Given sentence $x$ from the monolingual corpus, we use three types of noise to obtain the randomly perturbed text $\\hat{x}$. First, the word order is locally shuffled. Second, we randomly drop tokens of the sentence with a probability of $0.1$. Third, we substitute tokens with the special padding token P with a probability of $0.1$. The pre-training objective is to recover the original sentence $x$ by conditioning on $\\hat{x}$. The DAE loss is computed via: DAE(x) = -p(x|x) = -i = 1|x|p(xi | x, x<i) where $x_{<i}$ represents the tokens of previous time steps $x_1,\\cdots ,x_{i-1}$.\nSimilar to monolingual MLM, the masked token prediction task can be extended to cross-lingual settings BIBREF5. To be specific, given a parallel corpus, we concatenate the pair of bilingual sentences $(x,y)$ to a whole sequence, and use it as the input of MLM. The language tags are also fed into the model to indicate the languages of tokens. During training, we adopt the same masking strategy as monolingual MLM. Apart from using monolingual context to predict the masked tokens, XMLM encourages the model to utilize the alignment of bilingual sentences, so that the model learns to map cross-lingual texts into a shared vector space. Similar to eq:mlm, the cross-lingual MLM loss is: XMLM(x,y) = -i Mxp( xi | xMx , yMy)\n-i Myp( yi | xMx , yMy) where $M_x, M_y$ represent the masked positions of $x$ and $y$, respectively.\nIf only DAE is used as the pre-training task for the decoder, we found that the model ignores the target language tag while generating just the same language as the input, caused by the spurious correlation issue BIBREF25. In other words, the DAE loss captures the spurious correlation between the source language tag and the target sentences, but we expect the language of generated sentences can be controlled by the target language tag. To solve the above problem, we use machine translation as the cross-lingual auto-encoding (XAE) task, which decreases mutual information between the target sentences and the source language tag. XAE can be viewed as the multilingual-version DAE task in the sense that both of them recover the sentence by conditioning on the encoded representations. The cross-lingual auto-encoding loss is defined as: XAE(x,y) = -p(y|x) - p(x|y) where $(x,y)$ is a pair of sentences in the parallel corpus.\nMonolingual MLM The masked language modeling (MLM) (Devlin et al. 2019) task aims at predicting the randomly masked words according to their context. The objective pretrains the bidirectional encoder to obtain contextual representations. Following (Devlin et al. 2019), we randomly mask 15% of the tokens in a monolingual sentence.

Pauline Marois said that \"\"This means, among other things, that it’s another example of how Quebec could shine among the brightest ... as an independent country. We could continue to win our medals, I’m sure of that.\" Benfeito responded to a similar question from Canadian media when asked if she was as proud of the day as all the day's medalists were from Quebec athletes by saying that \"No, we are one big happy gang. We are equally as proud of our home in Quebec as we are of our home in Canada.\"\n\nAt the 2014 Commonwealth Games, she won a gold medal in the 10 m platform synchronised with Fillion, and gold in the 10 m platform individual.\n\nAt the 2016 Summer Olympics in Rio de Janeiro, Benfeito and Filion repeated their bronze medal performance in the 10 m platform synchro event, while Benfeito won an additional individual medal in the individual platform diving event.

        "answer": "Automated essay scoring is the task of assigning a score to an essay, usually in the context of assessing the language ability of a language learner.",
        "evidence": "A variety of approaches have been proposed for document quality assessment across different domains: Wikipedia article quality assessment, academic paper rating, content quality assessment in community question answering (cQA), and essay scoring. Among these approaches, some use hand-crafted features while others use neural networks to learn features from documents. For each domain, we first briefly describe feature-based approaches and then review neural network-based approaches. Wikipedia article quality assessment: Quality assessment of Wikipedia articles is a task that assigns a quality class label to a given Wikipedia article, mirroring the quality assessment process that the Wikipedia community carries out manually. Many approaches have been proposed that use features from the article itself, meta-data features (e.g., the editors, and Wikipedia article revision history), or a combination of the two. Article-internal features capture information such as whether an article is properly organized, with supporting evidence, and with appropriate terminology. For example, BIBREF3 use writing styles represented by binarized character trigram features to identify featured articles. BIBREF4 and BIBREF0 explore the number of headings, images, and references in the article. BIBREF5 use nine readability scores, such as the percentage of difficult words in the document, to measure the quality of the article. Meta-data features, which are indirect indicators of article quality, are usually extracted from revision history, and the interaction between editors and articles. For example, one heuristic that has been proposed is that higher-quality articles have more edits BIBREF6 , BIBREF7 . BIBREF8 use the percentage of registered editors and the total number of editors of an article. Article–editor dependencies have also been explored. For example, BIBREF9 use the authority of editors to measure the quality of Wikipedia articles, where the authority of editors is determined by the articles they edit. Deep learning approaches to predicting Wikipedia article quality have also been proposed. For example, BIBREF10 use a version of doc2vec BIBREF11 to represent articles, and feed the document embeddings into a four hidden layer neural network. BIBREF12 first obtain sentence representations by averaging words within a sentence, and then apply a biLSTM BIBREF13 to learn a document-level representation, which is combined with hand-crafted features as side information. BIBREF14 exploit two stacked biLSTMs to learn document representations.\nAcademic paper rating: Academic paper rating is a relatively new task in NLP/AI, with the basic formulation being to automatically predict whether to accept or reject a paper. BIBREF2 explore hand-crafted features, such as the length of the title, whether specific words (such as outperform, state-of-the-art, and novel) appear in the abstract, and an embedded representation of the abstract as input to different downstream learners, such as logistic regression, decision tree, and random forest. BIBREF15 exploit a modularized hierarchical convolutional neural network (CNN), where each paper section is treated as a module. For each paper section, they train an attention-based CNN, and an attentive pooling layer is applied to the concatenated representation of each section, which is then fed into a softmax layer.\nContent quality assessment in cQA: Automatic quality assessment in cQA is the task of determining whether an answer is of high quality, selected as the best answer, or ranked higher than other answers. To measure answer content quality in cQA, researchers have exploited various features from different sources, such as the answer content itself, the answerer's profile, interactions among users, and usage of the content. The most common feature used is the answer length BIBREF16 , BIBREF17 , with other features including: syntactic and semantic features, such as readability scores. BIBREF18 ; similarity between the question and the answer at lexical, syntactic, and semantic levels BIBREF18 , BIBREF19 , BIBREF20 ; or user data (e.g., a user's status points or the number of answers written by the user). There have also been approaches using neural networks. For example, BIBREF21 combine CNN-learned representations with hand-crafted features to predict answer quality. BIBREF22 use a 2-dimensional CNN to learn the semantic relevance of an answer to the question, and apply an LSTM to the answer sequence to model thread context. BIBREF23 and BIBREF24 model the problem similarly to machine translation quality estimation, treating answers as competing translation hypotheses and the question as the reference translation, and apply neural machine translation to the problem. Essay scoring: Automated essay scoring is the task of assigning a score to an essay, usually in the context of assessing the language ability of a language learner. The quality of an essay is affected by the following four primary dimensions: topic relevance, organization and coherence, word usage and sentence complexity, and grammar and mechanics. To measure whether an essay is relevant to its “prompt” (the description of the essay topic), lexical and semantic overlap is commonly used BIBREF25 , BIBREF26 . BIBREF27 explore word features, such as the number of verb formation errors, average word frequency, and average word length, to measure word usage and lexical complexity. BIBREF28 use sentence structure features to measure sentence variety. The effects of grammatical and mechanic errors on the quality of an essay are measured via word and part-of-speech $n$ -gram features and “mechanics” features BIBREF29 (e.g., spelling, capitalization, and punctuation), respectively. BIBREF30 , BIBREF31 , and BIBREF32 use an LSTM to obtain an essay representation, which is used as the basis for classification. Similarly, BIBREF33 utilize a CNN to obtain sentence representation and an LSTM to obtain essay representation, with an attention layer at both the sentence and essay levels.\nEssay scoring: Automated essay scoring is the task of assigning a score to an essay, usually in the context of assessing the language ability of a language learner.",

        "evidence": "The Patriots hired head coach Bill Belichick, who had served as defensive coordinator under Parcells including during Super Bowl XXXI, in 2000. Their new home field, Gillette Stadium, opened in 2002 to replace the aging Foxboro Stadium. Long–time starting quarterback Drew Bledsoe, who was the franchise's star throughout the 1990s, went down with a sheared blood vessel in his chest in a week two match–up in 2001 against the rival New York Jets. Backup quarterback Tom Brady, drafted by the Patriots in sixth round of the 2000 NFL draft, became the starting quarterback. Brady's successful play led to Bledsoe never getting his job back as a starter, and would serve as the franchise's starting quarterback for the next 18 years. Under Belichick and Brady, the Patriots became one of the most consistently dominant teams in the NFL, with many describing the team as a \"dynasty\". Within the first few seasons of the 21st century, the team won three Super Bowls in four seasons (2001, 2003, and 2004), over the St. Louis Rams, Carolina Panthers, and Philadelphia Eagles, respectively. The Patriots finished the 2007 regular season with a perfect 16–0 record, becoming only the fourth team in league history to go undefeated in the regular season, and the only one since the league expanded its regular season schedule to 16 games. After advancing to Super Bowl XLII, the team's fourth Super Bowl in seven years, the Patriots were upset by the Giants to end their bid for a 19–0 season. With the loss, the Patriots ended the year at 18–1, becoming only one of three teams to go 18–1 along with the 1984 San Francisco 49ers and the 1985 Chicago Bears. However, both the Bears and 49ers lost their only game during the regular season, and both would win their respective Super Bowl.\n\nThe Patriots returned to the Super Bowl in 2011 but lost again to the Giants, 21–17. In 2014, the Patriots reached a record-tying eighth Super Bowl, where they defeated the defending champion Seattle Seahawks by a score of 28–24 to win Super Bowl XLIX for their fourth title. After Seattle had driven the ball to New England's 1-yard line with under a minute to go, New England rookie cornerback Malcolm Butler made a critical interception on Seattle's final offensive play that helped to seal the victory. New England became the first team to reach nine Super Bowls in the 2016–17 playoffs and faced the Atlanta Falcons in Super Bowl LI. Losing 28–3 midway through the third quarter, the Patriots scored 25 unanswered points to tie the game in the final seconds of regulation. In the first overtime in Super Bowl history, the Patriots won the coin toss and scored a touchdown to claim their fifth Super Bowl victory. The Patriots extended their record to ten Super Bowl appearances in the 2017–18 playoffs but lost to the Philadelphia Eagles in Super Bowl LII.

        "evidence": "In this part, we introduce several heuristics of similarity measuring based on word embeddings. Notice that, we do not leverage supervised learning (e.g., full neural networks for sentence paring BIBREF27 , BIBREF28 ) to measure similarity, because it is costly to obtain labeled data of high quality.\nThe simplest approach, perhaps, is to sum over all word embeddings in an utterance as sentence-level features INLINEFORM0 . This heuristic is essentially the sum pooling method widely used in neural networks BIBREF29 , BIBREF30 , BIBREF27 . The cosine measure is used as the similarity score between two utterances INLINEFORM1 and INLINEFORM2 . Let INLINEFORM3 and INLINEFORM4 be their sentence vectors; then we have DISPLAYFORM0 \nwhere INLINEFORM0 is the INLINEFORM1 -norm of a vector.\nTo enhance the interaction between two successive sentences, we propose a more complicated heuristic as follows. Let INLINEFORM0 and INLINEFORM1 be a word in INLINEFORM2 and INLINEFORM3 , respectively. (Embeddings are denoted as bold alphabets.) Suppose further that INLINEFORM4 and INLINEFORM5 are the numbers of words in INLINEFORM6 and INLINEFORM7 . The similarity is given by DISPLAYFORM0 \nFor each word INLINEFORM0 in INLINEFORM1 , our intuition is to find the most related word in INLINEFORM2 , given by the INLINEFORM3 part; their relatedness is also defined by the cosine measure. Then the sentence-level similarity is obtained by the average similarity score of words in INLINEFORM4 . This method is denoted as heuristic-max.\nAlternatively, we may substitute the INLINEFORM0 operator in Equation ( EQREF16 ) with INLINEFORM1 , resulting in the heuristic-avg variant, which is equivalent to the average of word-by-word cosine similarity. However, as shown in Subsection SECREF22 , intensive similarity averaging has a “blurring” effect and will lead to significant performance degradation. This also shows that our proposed heuristic-max does capture useful interaction between two successive utterances in a dialogue.\nIn this part, we introduce several heuristics of similarity measuring based on word embeddings.

After the burst, with website creation being more accessible, tons of pages with bad user experience were created. As competition grew on the web during the early 2000s, website analysis tools became available, and awareness of website usability grew, internet marketers were prompted to produce measurables for their tactics and improve their website's user experience.\n\nIn 2004, new tools enabled internet marketers to experiment with website design and content variations to determine which layouts, copy text, offers, and images perform best. Testing started to be more accessible and known. This form of optimization accelerated in 2007 with the introduction of the free tool Google Website Optimizer. Today, optimization and conversion are key aspects of many digital marketing campaigns. A research study conducted among internet marketers in 2017, for example, showed that 50% of respondents thought that CRO was \"crucial to their overall digital marketing strategy\".\n\nConversion rate optimization shares many principles with direct response marketing – a marketing approach that emphasizes tracking, testing, and on-going improvement. Direct marketing was popularized in the early twentieth century and supported by the formation of industry groups such as the Direct Marketing Association, which was formed in 1917 and later named Data & Marketing Association and acquired by the Association of National Advertisers following the announcement on May 31, 2018.\n\nLike modern day conversion rate optimization, direct response marketers also practice A/B split-testing, response tracking, and audience testing to optimize mail, radio, and print campaigns.",

SQuAD provides no mapping of the answer contexts to Wikipedia, whereas WikiQA and SelQA provide mappings; however, their data do not come from the same version of Wikipedia. We propose an automatic way of mapping the answer contexts from all corpora to the same version of Wikipeda so they can be coherently used for answer retrieval.\nEach paragraph in Wikipedia is first indexed by Lucene using {1,2,3}-grams, where the paragraphs are separated by WikiExtractor and segmented by NLP4J (28.7M+ paragraphs are indexed). Each answer sentence from the corpora in Table TABREF3 is then queried to Lucene, and the top-5 ranked paragraphs are retrieved. The cosine similarity between each sentence in these paragraphs and the answer sentence is measured for INLINEFORM0 -grams, say INLINEFORM1 . A weight is assigned to each INLINEFORM2 -gram score, say INLINEFORM3 , and the weighted sum is measured: INLINEFORM4 . The fixed weights of INLINEFORM5 are used for our experiments, which can be improved.\nIf there exists a sentence whose INLINEFORM0 , the paragraph consisting of that sentence is considered the silver-standard answer passage. Table TABREF3 shows how robust these silver-standard passages are based on human judgement ( INLINEFORM1 ) and how many passages are collected ( INLINEFORM2 ) for INLINEFORM3 , where the human judgement is performed on 50 random samples for each case. For answer retrieval, a dataset is created by INLINEFORM4 , which gives INLINEFORM5 accuracy and INLINEFORM6 coverage, respectively. Finally, each question is queried to Lucene and the top- INLINEFORM7 paragraphs are retrieved from the entire Wikipedia. If the answer sentence exists within those retrieved paragraphs according to the silver-standard, it is considered correct.\nFinding a paragraph that includes the answer context out of the entire Wikipedia is an extremely difficult task (128.7M). The last row of Table TABREF3 shows results from answer retrieval. Given INLINEFORM0 , SelQA and SQuAD show about 34% and 35% accuracy, which are reasonable.

        "answer": "Yes, it is.",
        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation.

        "evidence": "Nature, in the broadest sense, is the physical world or universe. \"Nature\" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.\n\nThe word nature is borrowed from the Old French nature and is derived from the Latin word natura, or \"essential qualities, innate disposition\", and in ancient times, literally meant \"birth\". In ancient philosophy, natura is mostly used as the Latin translation of the Greek word physis (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socratic philosophers (though this word had a dynamic dimension then, especially for Heraclitus), and has steadily gained currency ever since.\n\nDuring the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions (Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn at the same time, especially after Charles Darwin.\n\nWithin the various uses of the word today, \"nature\" often refers to geology and wildlife. Nature can refer to the general realm of living plants and animals, and in some cases to the processes associated with inanimate objects—the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth. It is often taken to mean the \"natural environment\" or wilderness—wild animals, rocks, forest, and in general those things that have not been substantially altered by human intervention, or which persist despite human intervention. For example, manufactured objects and human interaction generally are not considered part of nature, unless qualified as, for example, \"human nature\" or \"the whole of nature\". This more traditional concept of natural things that can still be found today implies a distinction between the natural and the artificial, with the artificial being understood as that which has been brought into being by a human consciousness or a human mind. Depending on the particular context, the term \"natural\" might also be distinguished from the unnatural or the supernatural.",

A predictive model further validates our feature sets, and also allows us to analyze dogmatism in millions of other Reddit comments in a scalable way, with multiple uses in ongoing, downstream analyses.\nPrediction task. Our goal is (1) to understand how well we can use the strategies in Section 3 to predict dogmatism, and (2) to test the domain-independence of these strategies. First, we test the performance of our model under cross-validation within the Reddit comment dataset. We then evaluate the Reddit-based model on a held out corpus of New York Times comments annotated using the technique in Section 2. We did not refer to this second dataset during feature construction.\nFor classification, we consider two classes of comments: dogmatic and non-dogmatic. As in the prior analysis, we draw these comments from the top and bottom quartiles of the dogmatism distribution. This means the classes are balanced, with 2,500 total comments in the Reddit training data and 500 total comments in the New York Times testing data.\nWe compare the predictions of logistic regression models based on unigram bag-of-words features (BOW), sentiment signals (SENT), the linguistic features from our earlier analyses (LING), and combinations of these features. BOW and SENT provide baselines for the task. We compute BOW features using term frequency-inverse document frequency (TF-IDF) and category-based features by normalizing counts for each category by the number of words in each document. The BOW classifiers are trained with regularization (L2 penalties of 1.5).\nClassification results. We present classification accuracy in Table 2 . BOW shows an AUC of 0.853 within Reddit and 0.776 on the held out New York Times comments. The linguistic features boost classification results within Reddit (0.881) and on the held out New York Times comments (0.791). While linguistic signals by themselves provide strong predictive power (0.801 AUC within domain), sentiment signals are much less predictive.\nThese results suggest that linguistic features inspired by prior efforts in psychology are useful for predicting dogmatism in practice and generalize across new domains.\nWe now show how we can use the linguistic feature sets we have described to build a classifier that predicts dogmatism in comments.",

        "evidence": "We empirically validate EGL on speech recognition tasks. In our experiments, the RNN takes in spectrograms of utterances, passing them through two 2D-convolutional layers, followed by seven bi-directional recurrent layers and a fully-connected layer with softmax activation. All recurrent layers are batch normalized. At each timestep, the softmax activations give a probability distribution over the characters. CTC loss BIBREF8 is then computed from the timestep-wise probabilities.\nA base model, INLINEFORM0 , is trained on 190 hours ( INLINEFORM1 100K instances) of transcribed speech data. Then, it selects a subset of a 1,700-hour ( INLINEFORM2 1.1M instances) unlabeled dataset. We query labels for the selected subset and incorporate them into training. Learning rates are tuned on a small validation set of 2048 instances. The trained model is then tested on a 156-hour ( INLINEFORM3 100K instances) test set and we report CTC loss, Character Error Rate (CER) and Word Error Rate (WER).\nThe confidence score methods BIBREF1 , BIBREF2 can be easily extended to our setup. Specifically, from the probabilities over the characters, we can compute an entropy per timestep and then average them. This method is denoted as entropy. We could also take the most likely prediction and calculate its CTC loss, normalized by number of timesteps. This method is denoted as pCTC (predicted CTC) in the following sections.\nWe implement EGL by marginalizing over the most likely 100 labels, and compare it with: 1) a random selection baseline, 2) entropy, and 3) pCTC. Using the same base model, each method queries a variable percentage of the unlabeled dataset. The queries are then included into training set, and the model continues training until convergence. Fig. FIGREF9 reports the metrics (Exact values are reported in Table TABREF12 in the Appendix) on the test set as the query percentage varies. All the active learning methods outperform the random baseline. Moreover, EGL shows a steeper, more rapid reduction in error than all other approaches. Specifically, when querying 20% of the unlabeled dataset, EGL has 11.58% lower CER and 11.09% lower WER relative to random. The performance of EGL at querying 20% is on par with random at 40%, suggesting that using EGL can lead to an approximate 50% decrease in data labeling.\nThis suggests EGL is able to identify aspects of an instance that uncertainty-based measurements cannot capture.",

        "question": "How do you fix a puncture on a Mountain Bike?",
        "evidence": "",
        "answer": "Step 1. Find the puncture\nUsing the valve as your starting point, closely inspect the tread of the tyre to find the cause of the puncture.\nPay close attention to the sidewalls (the non-treaded portion on the side of the tyre where the pressure and size information is printed/moulded) to make sure there are no tears or holes.\nRemove any glass, grit or other debris that you spot. A small flat-head screwdriver or awl is the best tool for this, but be careful not to dig too deep. A small set of pliers can also be useful for removing embedded thorns.\nEven if you find one possible cause of the puncture, continue checking the tyre thoroughly until you get back to the valve because there could well be more.\n\nStep 2. Remove the inner tube\nLet the air out of the inner tube and push the valve up into the tyre, unscrewing and retaining the valve lockring if fitted.\nOn the side of the wheel opposite the valve, slip a tyre lever under the tyre’s bead and a further tyre lever about roughly 5cm away.\nPull the nearer tyre lever towards you, lifting the tyre’s bead over the edge of the rim. Continue until one bead of the tyre is completely free of the rim then pull the tube out.\nRemove the tyre completely from the rim – with most tyres this can be done by hand unless they are exceptionally tight.\n\nStep 3. Locate the puncture on the inner tube\nIf you are just going to replace the inner tube, move to step 6.\nIf you want to patch the inner tube – and you ought to, it’s not that hard! – inflate the tube and listen for air escaping.\nIf you’re struggling to find the hole by listening alone, try passing your lips over the top of the tube.\nIf the hole still can’t be found, re-inflate the tube and pass it through a bowl of water, or rub the tube down with soapy water, until you spot escaping bubbles. Be sure to dry the tube before proceeding to the next step.\n\nStep 4. Prepare the inner tube for patching\nSelect an appropriately sized patch – if in doubt, err on the side of caution and use a bigger rather than smaller patch.\nRoughen the surface of the tube around the hole with sandpaper (usually included with any good puncture repair kit).\nEnsure that any moulding marks on the tube are completely flattened down because these can cause issues when glueing. Thoroughly brush off any rubber ‘shavings’. Cleanliness is key when repairing a puncture.\nIf you’re using pre-glued patches – such as Park’s popular GP-2 patch kit – you can now patch the hole. Thoroughly press down on the patch to ensure it’s fully in contact with the tube.\nIf you’re using a ‘traditional’ glue-on patch kit, start by applying a generous drop of glue – or rubber cement by its proper name – to the tube and spread this across an area slightly larger than the patch you intend to use. Allow this to dry.\nSimilarly, apply a second, thinner layer. Once again, allow to dry – when the glue is dry, its surface will change from a shiny to a matte finish.\nThe key to ensuring a good long-lasting puncture repair is patience, so don’t rush this step.\n\nStep 5. Patching an inner tube\nFirmly press the patch into place after removing the backing foil – cleanliness is also key to a good repair, so leave removing the foil until the very last moment.\nIf there’s a thin cellophane backing on the patch, it can be left on. It’s good practice to dust any stray glue with chalk, talcum powder or fine road dust to prevent it from sticking to the inside of the tyre casing.\n\nStep 6. Inspect the tyre casing and rim tape\nBefore refitting the tube, thoroughly double/triple-check the inside of the tyre casing – there’s nothing more frustrating than going to the effort of patching a tube only to puncture it again with a stray thorn you may have missed.\nIt’s also good practice to check the rim tape. If a hard plastic rim strip – often found on cheaper bikes – is torn, it leaves a sharp edge that can easily slice a tube.\nLikewise, if your rim tape has slipped, it can leave eyelets or spoke holes exposed, which can also puncture a tube.\nIf you have persistent problems with your rim tape puncturing your tube, try swapping it out for new tape tape \n\n\nStep 7. Refit the tyre\nAfter repairing the tube and thoroughly checking the tyre, refit one side of the tyre – one bead, to use the correct term – to the rim.\nSlightly inflate the tube (just enough to give it structure) and refit it to the wheel, putting the valve through its hole first.\nStarting at the opposite side of the rim to the valve, use your thumbs to lift the tyre’s bead over the rim. Work your way around the rim until there’s just one small section of the tyre left.\nPush the valve up into the tyre and then, using your thumbs, ease the remaining section of the tyre’s bead over the edge of the rim.\nIf the tyre is particularly tight, avoid the temptation to use a tyre lever to push the last section of the tyre onto the rim – you’ll almost certainly pinch your inner tube doing so.\nIf you’re struggling to pop the tyre onto the wheel, try putting the tyre on the ground, holding it in place with your feet and rolling the bead back toward you – heavy gloves really help here. This takes a little practice but should work with even the most stubborn tyres.\n\n\nStep 8. Check the repair and inflate the tyre\nCheck that the tube isn’t trapped between the rim and the tyre bead by working your way around the tyre, pushing the bead into the well of the rim.\nIf the tube is trapped, try ‘massaging’ the tyre to encourage it to seat properly. Pumping it up a small amount may also help to seat the tube properly.\nInflate the tyre to a point where it feels soft but has maintained its shape. Then check that the moulding mark around the tyre follows the rim evenly all the way around.\nIf not, deflate a little and ease any high spots down and pull low spots up until the bead is fitted evenly.\nInflate fully and check once again that the tyre’s bead is still seated evenly and that the tyre isn’t lifting off the rim at any point, then adjust your pressures to suit.",

        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nIn this work we focus on the Spanish language variety identification.",

Engine:  F1 cars have extremely powerful engines that can generate around 1000 bhp at up to 20,000 rpm\n2. Power-to-Weight ratio: F1 cars are also extremely light at around 800 kgs giving them a power-to-weight ratio of 12000-1400 hp/ton. For comparison, the best Porsche cars have a power-to-weight ratio of only 300-400 hp/ton.\n2. Aerodynamics: F1 cars are fitted with extremely sophisticated aerodynamics including a rear wing, front wing and body parts that help reduce aerodynamic drag for straight-line speeds while adding downforce to help around corners\n3. Tires: F1 tires are extremely large and sticky. This help the cars stick to the road as the car goes through turns very fast.\n4. Brakes: Lastly F1 brakes are very powerful and can slow down a car extremely quickly. This allows F1 cars to be at top speed for much longer before needing to slow down for taking a turn.",

        "evidence": "The proposed model architecture is shown in the Figure 1 . Recurrent Neural Networks like LSTM, GRU update their weights at every timestep sequentially and hence lack parallelization over inputs in training. In case of attention based models, the attention layer has to wait for outputs from all timesteps. Hence, these models fail to take the advantage of parallelism either. Since, proposed model is based on convolution layers and gated mechanism, it can be parallelized efficiently. The convolution layers learn higher level representations for the source domain. The gated mechanism learn the domain agnostic representations. They together control the information that has to flow through further fully connected output layer after max pooling.\nWe find that gated architectures vastly outperform non gated CNN model. The effectiveness of gated architectures rely on the idea of training a gate with sole purpose of identifying a weightage. In the task of sentiment analysis this weightage corresponds to what weights will lead to a decrement in final loss or in other words, most accurate prediction of sentiment. In doing so, the gate architecture learns which words or n-grams contribute to the sentiment the most, these words or n-grams often co-relate with domain independent words. On the other hand the gate gives less weightage to n-grams which are largely either specific to domain or function word chunks which contribute negligible to the overall sentiment. This is what makes gated architectures effective at Domain Adaptation.\nWe see that gated architectures almost always outperform recurrent, attention and linear models BoW, TFIDF, PV. This is largely because while training and testing on same domains, these models especially recurrent and attention based may perform better. However, for Domain Adaptation, as they lack gated structure which is trained in parallel to learn importance, their performance on target domain is poor as compared to gated architectures. As gated architectures are based on convolutions, they exploit parallelization to give significant boost in time complexity as compared to other models.

        "question": "Is there any room for improvement on the CBT?",
        "answer": "Yes, they show in their own human study that there is still room for improvement on the CBT beyond the performance of their model.",
        "evidence": "Since humans amass more and more generally available data in the form of unstructured text it would be very useful to teach machines to read and comprehend such data and then use this understanding to answer our questions. A significant amount of research has recently focused on answering one particular kind of questions the answer to which depends on understanding a context document. These are cloze-style questions BIBREF0 which require the reader to fill in a missing word in a sentence. An important advantage of such questions is that they can be generated automatically from a suitable text corpus which allows us to produce a practically unlimited amount of them. That opens the task to notoriously data-hungry deep-learning techniques which now seem to outperform all alternative approaches.\nTwo such large-scale datasets have recently been proposed by researchers from Google DeepMind and Facebook AI: the CNN/Daily Mail dataset BIBREF1 and the Children's Book Test (CBT) BIBREF2 respectively. These have attracted a lot of attention from the research community BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 with a new state-of-the-art model coming out every few weeks.\nHowever if our goal is a production-level system actually capable of helping humans, we want the model to use all available resources as efficiently as possible. Given that\nwe believe that if the community is striving to bring the performance as far as possible, it should move its work to larger data.\nThis thinking goes in line with recent developments in the area of language modelling. For a long time models were being compared on several \"standard\" datasets with publications often presenting minuscule improvements in performance. Then the large-scale One Billion Word corpus dataset appeared BIBREF15 and it allowed Jozefowicz et al. to train much larger LSTM models BIBREF16 that almost halved the state-of-the-art perplexity on this dataset.\nWe think it is time to make a similar step in the area of text comprehension. Hence we are introducing the BookTest, a new dataset very similar to the Children's Book test but more than 60 times larger to enable training larger models even in the domain of text comprehension. Furthermore the methodology used to create our data can later be used to create even larger datasets when the need arises thanks to further technological progress.\nWe show that if we evaluate a model trained on the new dataset on the now standard Children's Book Test dataset, we see an improvement in accuracy much larger than other research groups achieved by enhancing the model architecture itself (while still using the original CBT training data). By training on the new dataset, we reduce the prediction error by almost one third. On the named-entity version of CBT this brings the ensemble of our models to the level of human baseline as reported by Facebook BIBREF2 . However in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.\nHowever in the final section we show in our own human study that there is still room for improvement on the CBT beyond the performance of our model.",

The generation of graph pieces is similar to the generation of a sentence using RNNs, except that the token is graph pieces instead of words. Since each graph piece is a subgraph, the generated graph pieces then form an incomplete molecular graph where inter-piece bonds are absent. We use a GNN with the same structure as our encoder in Section 3.2 to predict the missing inter-piece bonds on the incomplete molecular graph, which can be formalized as a link prediction task. We have updated the description of our model structure as well as the Fig 5 (Fig 4 in the current version) for better understanding.",
        "evidence": "With a molecule G represented as {P i }, { Ẽij } , our model generates {P i } and { Ẽij } in two consecutive phases. The two phases move from coarse to fine granularity.\nPiece-level Sequence Generation Given a latent variable z, our model first uses an autoregressive sequence generation model P (P i |P <i , z) to decode a sequence of graph pieces [P 1 , . . . , P n ] 2 . During training, we insert two special tokens \"<bos>\" and \"<eos>\" into the begin and the end of the graph piece sequence to indicate the begin and the end, respectively. During testing, the generation stops when a \"<eos>\" is generated. The sequence model can be RNNs, such as LSTM and GRU. In this work, we use a single layer of GRU and project the latent variable z to the initial state of GRU.

Given nodes v and u, we predict their connections as follows:\nwhere H θ is a neural network. In this work we adopt a 3-layer MLP with ReLU activation. Apart from the types of chemical bonds, we also add a special type \"<none>\" to the edge vocabulary which indicates there is no connection between two nodes. During training, we predict both P (e uv ) and P (e vu ) to let H θ learn the undirected nature of chemical bonds. We use negative sampling to balance the ratio of \"<none>\" and chemical bonds. Since only about 2% pairs of nodes has inter-piece connections, negative sampling significantly improves the computational efficiency and scalability. The training objective of this stage is to minimize the loglikelihood L Ẽ of the ground truth inter-piece connections:\nThe reconstruction loss of our GP-VAE model is:\nTo decode { Ẽij } in inference time, the decoder first assigns all possible inter-piece connections with a bond type and a corresponding confidence level. We try to add bonds that have a confidence level higher than δ th = 0.5 to the molecule in order of confidence level from high to low. For each attempt, we perform a valency check and a cycle check to reject the connections that will cause violation of valency or form unstable rings which are too small or too large. Since this procedure may form unconnected graphs, we find the maximal connected component as the result of the generation. We present the pseudo code for inference in Appendix C.\nWe jointly train a 2-layer MLP from z to predict the scores of target properties using the MSE loss. Denote the loss of the predictor as L prop , the loss function of our GP-VAE is:\nwhere α and β balance the reconstruction loss, the property loss, and the KL divergence D KL between the distribution of z and the prior distribution N (0, I).\nFigure 4: Overview of the graph piece variational autoencoder.

        "evidence": "",
        "answer": "I can’t remember the last time I kept a journal. I used to write constantly as a little girl: in colorful notebooks gifted to me at Christmas or on my birthday. I always abandoned them when they were half full. Maybe a quarter if I was “busy.” The truth is, I abandoned them when I realized no one but me cared about what I had to say; when I had stopped caring; when I realized I wasn’t particularly profound. That may happen this time around, too.\n\nThe difference now is that even if I don’t say anything profound: the timing is profound. We’re living through a global pandemic, hiding in our homes, hoping we aren’t infected and unknowingly infecting others. Avoiding people on the sidewalk when we go for walks, immediately wanting to wash our hands when picking something up after the grocery store after waiting in line for an hour.\n\nYesterday, it was my turn to go grocery shopping. My partner had been making the majority of our runs. The last time I joined him was weeks ago, before you could expect a line around the block. We had woken up early on a Saturday, and it was lightly raining, so I convinced him we should go to the Mollie Stones up the street to beat everyone there. About 12 people were lined up when we arrived, and we huddled under a tiny floral umbrella that lives in the trunk of our car.\n\nI had charged this particular umbrella to my corporate card when on a work trip to London, and even though it’s barely functional, I won’t throw it out. Opening it to cover us while waiting outside Mollie Stones, I daydreamed of going back to London. Of traveling at all. Of being able to run into a grocery store for brunch ingredients, and nothing more. Mollie Stones was always our destination for brunch ingredients after a particularly aggressive night out. I missed nights out: crowded bars where you had to raise your voice just to be heard, and yet were still annoyed when your best friend would scream into your ear. \n\nI managed to get through that trip to Mollie Stones without crying. The last time my partner and I went to that Mollie Stones, it was the Sunday before Mayor Breed directed San Francisco to shelter in place. There weren’t any social distancing requirements, and the store was overrun by frantic shoppers. People bumped into each other in the aisles. The paper goods had been ransacked. The oat milk was nowhere to be found. We chose Mollie Stones because it’s the most expensive grocery store in San Francisco, and we didn’t think everyone would be stocking up there. But this is San Francisco, so we were wrong. I saw an elderly woman moving slowly through the store and started to hyperventilate. My partner wasn’t far, so I managed to find him and take a few deep breaths so I could avoid a panic attack.\n\nSo, you can understand why I wasn’t looking forward to my first solo grocery run. I chose the Costco in SOMA because so few people live south of Market, and it was the middle of the work week: maybe you can sneak away from Zoom meetings for a quick trip to Whole Foods or Trader Joe’s, but Costco is an adventure, a commitment. Well, hundreds were as committed as I was. Probably to securing 30 rolls of toilet paper.\n\nI pulled into the Costco parking garage at 10am as it was opening. No cars waiting to enter, which I took as a good sign. Note to self: there are no good signs in a pandemic. After I finally found a parking spot, I meandered around the lot only to find myself at the back of what felt like a makeshift never-ending airport security line, hastily created with caution tape and lazily monitored by a Costco employee in a face mask with megaphone. Every few minutes, he would remind us to stay six feet apart.\n\nDespite being hopeful about the wait, I came prepared. My face was completely covered by a N95 mask, which I admit, I felt guilty about. Healthcare workers all over America needed PPE, and here I was, waiting in line at Costco wearing one piece of the ensemble. I had purchased a 10-pack after the last fire season and had broken the seal on the pack, making them impossible to donate. My mask makes me feel like a child or a cartoon character: it spans from my chin to the bottom of my eyelids. To complement it, I’m rocking ski gloves (plastic are almost impossible to come by), and have multiple episodes of The Daily downloaded on my phone. I take my spot at the back of the line, which has six or so switchbacks, and settle in to catch up with Michael Barbaro. \n\nI’ve been listening to The Daily for over a year now: almost everyday, either on my commute or while working out in the morning. But since quarantining, I’ve sadly kicked the habit. Without a gym or a ride to work, it doesn’t easily fit into my schedule. I miss Michael’s “and here’s what else you need to know today.”\n\nThe first episode up features a conversation with Paul Mozur, a technology reporter based in Asia — originally Shanghai. He, along with a handful of other American reporters, were unceremoniously banned from China and forced to leave the country, and he shared both his emotional reaction and the reasons why. \n\nI then chose “voices of the pandemic,” an episode cut into four parts: reporters talking to Americans impacted by the pandemic in Pittsburgh, Kansas City, New York and Seattle. Parents who are now homeschooling their screaming toddlers. A former waitress now living in her car trying to get a job at a grocery store, but unable to locate her birth certificate. A nurse who can no longer see her grandchildren because she’s treating COVID patients. I teared up listening to her recall the first night in the hospital when they confirmed two cases of COVID-19. She felt a sense of purpose and camaraderie with her coworkers, but realized almost immediately that it meant she wouldn’t be able to host her weekly sleepover with her grandchildren. She described in detail the room she decorated for them in her house, and how their beds will remain empty for weeks.\n\nThree Daily episodes in, and I’m finally making progress in the Costco line, winding up the ramp, where red tape at our feet clearly marks the required 6-foot gap between you and the people in front and behind you. Once inside the massive warehouse, I chart a course to the paper goods and make it my mission to secure toilet paper and paper towels. A success on that front makes the wait feel worthwhile, and I start to check items off my list with purpose. Although Costco employees are strategically placed throughout the warehouse, every so often lifting a megaphone to remind shoppers to stay six feet apart, there are a few ways that make this Costco trip rather typical: I pack my shopping cart to the brim, spend far too much money, and rush out the door. More than anything, I can’t wait to take my mask off.",

One of the founding members of the influential and experimental art punk band Wire, he branched out into electronic music, performance art, music production, and DJing during the band's extended periods of inactivity. He left Wire in 2004, and has since been focusing on solo work and collaborations with visual artists and fellow experimental musicians.\n\nWire released three albums between 1976 and 1979, Pink Flag, Chairs Missing and 154, before temporarily disbanding after a show at London's Electric Ballroom at the start of 1980. At this time, Gilbert formed a series of bands/projects with Wire's bassist, Graham Lewis, including Cupol, Dome, P'o, and Duet Emmo. Gilbert's collaborations with Lewis were experimental, featuring ambient music and found sounds. Dome performed at art galleries with visual displays that allowed audience interactivity. Gilbert and Lewis performed with tubes made of paper over their heads, thus restricting their vision. Artist Russell Mills frequently collaborated with Dome. In 1980, Gilbert and Lewis produced The The's debut single \"Black & White/Controversial Subject\" for 4AD, as well as the single \"Drop/So\" by A.C. Marias for their own Dome label. Between 8 and 31 August 1981, Gilbert, Lewis, and Mills took over London's Waterloo Gallery and produced MZUI, an interactive audio-visual installation where visitors were encouraged to play a number of instruments created by the artists from objects found on the site. The MZUI album, released by Cherry Red in May 1982, contains two untitled pieces based on recordings from the venue, finishing with the looped and distorted voice of Marcel Duchamp, whom Gilbert considers a key influence.

        "answer": "It learns to control the information flow between the unstructured and structured inputs.",
        "evidence": "Question Generation (QG) is the task of automatically creating questions from a range of inputs, such as natural language text BIBREF0, knowledge base BIBREF1 and image BIBREF2. QG is an increasingly important area in NLP with various application scenarios such as intelligence tutor systems, open-domain chatbots and question answering dataset construction. In this paper, we focus on question generation from reading comprehension materials like SQuAD BIBREF3. As shown in Figure FIGREF1, given a sentence in the reading comprehension paragraph and the text fragment (i.e., the answer) that we want to ask about, we aim to generate a question that is asked about the specified answer.\nQuestion generation for reading comprehension is firstly formalized as a declarative-to-interrogative sentence transformation problem with predefined rules or templates BIBREF4, BIBREF0. With the rise of neural models, Du2017LearningTA propose to model this task under the sequence-to-sequence (Seq2Seq) learning framework BIBREF5 with attention mechanism BIBREF6. However, question generation is a one-to-many sequence generation problem, i.e., several aspects can be asked given a sentence. Zhou2017NeuralQG propose the answer-aware question generation setting which assumes the answer, a contiguous span inside the input sentence, is already known before question generation. To capture answer-relevant words in the sentence, they adopt a BIO tagging scheme to incorporate the answer position embedding in Seq2Seq learning. Furthermore, Sun2018AnswerfocusedAP propose that tokens close to the answer fragments are more likely to be answer-relevant. Therefore, they explicitly encode the relative distance between sentence words and the answer via position embedding and position-aware attention.\nAlthough existing proximity-based answer-aware approaches achieve reasonable performance, we argue that such intuition may not apply to all cases especially for sentences with complex structure. For example, Figure FIGREF1 shows such an example where those approaches fail. This sentence contains a few facts and due to the parenthesis (i.e. “the area's coldest month”), some facts intertwine: “The daily mean temperature in January is 0.3$^\\circ $C” and “January is the area's coldest month”. From the question generated by a proximity-based answer-aware baseline, we find that it wrongly uses the word “coldest” but misses the correct word “mean” because “coldest” has a shorter distance to the answer “0.3$^\\circ $C”.\nIn summary, their intuition that “the neighboring words of the answer are more likely to be answer-relevant and have a higher chance to be used in the question” is not reliable. To quantitatively show this drawback of these models, we implement the approach proposed by Sun2018AnswerfocusedAP and analyze its performance under different relative distances between the answer and other non-stop sentence words that also appear in the ground truth question. The results are shown in Table TABREF2. We find that the performance drops at most 36% when the relative distance increases from “$0\\sim 10$” to “$>10$”. In other words, when the useful context is located far away from the answer, current proximity-based answer-aware approaches will become less effective, since they overly emphasize neighboring words of the answer.\nTo address this issue, we extract the structured answer-relevant relations from sentences and propose a method to jointly model such structured relation and the unstructured sentence for question generation. The structured answer-relevant relation is likely to be to the point context and thus can help keep the generated question to the point. For example, Figure FIGREF1 shows our framework can extract the right answer-relevant relation (“The daily mean temperature in January”, “is”, “32.6$^\\circ $F (0.3$^\\circ $C)”) among multiple facts. With the help of such structured information, our model is less likely to be confused by sentences with a complex structure. Specifically, we firstly extract multiple relations with an off-the-shelf Open Information Extraction (OpenIE) toolbox BIBREF7, then we select the relation that is most relevant to the answer with carefully designed heuristic rules.\nNevertheless, it is challenging to train a model to effectively utilize both the unstructured sentence and the structured answer-relevant relation because both of them could be noisy: the unstructured sentence may contain multiple facts which are irrelevant to the target question, while the limitation of the OpenIE tool may produce less accurate extracted relations. To explore their advantages simultaneously and avoid the drawbacks, we design a gated attention mechanism and a dual copy mechanism based on the encoder-decoder framework, where the former learns to control the information flow between the unstructured and structured inputs, while the latter learns to copy words from two sources to maintain the informativeness and faithfulness of generated questions.\nIn the evaluations on the SQuAD dataset, our system achieves significant and consistent improvement as compared to all baseline methods. In particular, we demonstrate that the improvement is more significant with a larger relative distance between the answer and other non-stop sentence words that also appear in the ground truth question. Furthermore, our model is capable of generating diverse questions for a single sentence-answer pair where the sentence conveys multiple relations of its answer fragment.\nTo explore their advantages simultaneously and avoid the drawbacks, we design a gated attention mechanism and a dual copy mechanism based on the encoder-decoder framework, where the former learns to control the information flow between the unstructured and structured inputs, while the latter learns to copy words from two sources to maintain the informativeness and faithfulness of generated questions.",

While much EHR data are structured and amenable to analysis, there appears to be limited homogeneity in data completeness and quality BIBREF1, and it is estimated that the majority of healthcare data are being generated in unstructured, text-based format BIBREF2. The generation and storage of these unstructured data come concurrently with policy initiatives that seek to utilize preventative measures to reduce hospital admission and readmission BIBREF3.\nChronic illnesses, behavioral factors, and social determinants of health are known to be associated with higher risks of hospital readmission, BIBREF4 and though behavioral factors and social determinants of health are often determined at the point of care, their identification may not always be curated in structured format within the EHR in the same manner that other factors associated with routine patient history taking and physical examination are BIBREF5. Identifying these patient attributes within EHRs in a reliable manner has the potential to reveal actionable associations which otherwise may remain poorly defined.\nAs EHRs act to streamline the healthcare administration process, much of the data collected and stored in structured format may be those data most relevant to reimbursement and billing, and may not necessarily be those data which were most relevant during the clinical encounter. For example, a diabetic patient who does not adhere to an insulin treatment regimen and who thereafter presents to the hospital with symptoms indicating diabetic ketoacidosis (DKA) will be treated and considered administratively as an individual presenting with DKA, though that medical emergency may have been secondary to non-adherence to the initial treatment regimen in the setting of diabetes. In this instance, any retrospective study analyzing only the structured data from many similarly selected clinical encounters will necessarily then underestimate the effect of treatment non-adherence with respect to hospital admissions.\nWhile this form of high context information may not be found in the structured EHR data, it may be accessible in patient notes, including nursing progress notes and discharge summaries, particularly through the utilization of natural language processing (NLP) technologies. BIBREF6, BIBREF7 Given progress in NLP methods, we sought to address the issue of unstructured clinical text by defining and annotating clinical phenotypes in text which may otherwise be prohibitively difficult to discern in the structured data associated with the text entry. For this task, we chose the notes present in the publicly available MIMIC database BIBREF8.\nGiven the MIMIC database as substrate and the aforementioned policy initiatives to reduce unnecessary hospital readmissions, as well as the goal of providing structure to text, we elected to focus on patients who were frequently readmitted to the ICU BIBREF9. In particular, a patient who is admitted to the ICU more than three times in a single year. By defining our cohort in this way we sought to ensure we were able to capture those characteristics unique to the cohort in a manner which may yield actionable intelligence on interventions to assist this patient population.\nGiven progress in NLP methods, we sought to address the issue of unstructured clinical text by defining and annotating clinical phenotypes in text which may otherwise be prohibitively difficult to discern in the structured data associated with the text entry.",

        "evidence": "We test the SotA offline RL method conservative Q-learning (CQL) ) and online RL method Randomized Ensembled Double Q-learning (REDQ) under the offline-online setting. Here, we choose a widely used locomotion task Hopper, and use the dataset hopper-medium-replay-v0 in the D4RL benchmark  as the offline dataset, which contains diverse experiences from different policies. Specifically, we first pre-train the agent with the offline dataset for 100K steps. Then, the agent is fine-tuned online by alternately conducting the interaction and updating process, where the agent interacts with the environment for 1K steps, and is updated for 10K steps. Such interleaving process ends until the total online interaction steps reach 90K.\nThe offline-online setting in this task should be a favourable one for policy learning, because both diverse offline data and online interactions are available here. Therefore, we expect following results: the initial offline training using the dataset will provide a relatively good but not perfect starting point for the agent, and then the agent can be further improved by the online alternating process since online interaction data can be obtained, and finally we may acquire a well-performed policy, even with normalized score close to or better than 100 (i.e., the performance of an expert).\nNonetheless, experiment results are shown in Figure, and they do not totally meet our expectation. Specifically, starting points of two curves show that the offline algorithm CQL and online algorithm REDQ can both obtain normalized scores greater than 0 (i.e., the performance of a random policy) but not very high after the initial offline training process. This result is what we expected, because CQL is designed for the offline setting, and online off-policy methods, such as REDQ, can also learn from the diverse and large offline dataset even though it is fixed. However, although the starting scores (below 30) are far from the expert score and leave a large room for further promoting, both algorithms have troubles in the following online process. REDQ suffers from severe instability issue and its performance drops significantly during online learning, and in the end, the policy almost degenerates into a random one. One the other hand, even though the CQL agent can keep stable during learning, its improvement is very limited.\nThese results indicate that pure online RL algorithm may be problematic for effectively handling offline data and online interaction data in a single training process, and pure offline RL algorithm cannot make good use of valuable online interaction data due to its conservative updating strategy. Such observation motivates us to couple them in an organic way.\nWe test the SotA offline RL method conservative Q-learning (CQL) (Kumar et al., 2020) and online RL method Randomized Ensembled Double Q-learning (REDQ) (Chen et al., 2021) under the offline-online setting.

All of the training set sizes \\leq 8000 are  as mentioned in Section 3. Note that the training datasets are different because different numbers of accelerator designs obtained initially via random sampling may be feasible for different applications.",
        "evidence": "Our template-based parameterization maps the accelerator, denoted as x, to a discrete design space,\nand each x i is a discrete-valued variable representing one component of the microarchitectural template, as shown in Table (See Appendix C for the description of other accelerator search spaces studied in our work). A design maybe be infeasible due to various reasons, such as a compilation failure or the limitations of physical implementation, and we denote the set of all such feasibility criterion as Feasible(x). The feasibility criterion depends on both the target software and the underlying hardware, and it is not easy to identify if a given x is infeasible without explicit simulation. We will require our optimization procedure to not only learn the value of the objective function but also to learn to navigate through a sea of infeasible solutions to high-performing feasible solutions x * satisfying Feasible(x * ) = 1.\nOur training dataset D consists of a modest set of accelerators x i that are randomly sampled from the design space and evaluated by the hardware simulator. We partition the dataset D into two subsets, D feasible and D infeasible . Let f (x) denote the desired objective (e.g., latency, power, etc.) we intend to optimize over the space of accelerators x. We do not possess functional access to f (x), and the optimizer can only access f (x) values for accelerators x in the feasible partition of the data, D feasible . For all infeasible accelerators, the simulator does not provide any value of f (x). In addition to satisfying feasibility, the optimizer must handle explicit constraints on parameters such as area and power. In our applications, we impose an explicit area constraint, Area(x) ≤ α 0 , though additional explicit constraints are also possible. To account for different constraints, we formulate this task as a constrained optimization problem. Formally:\nWhile Equation 1 may appear similar to other standard black-box optimization problems, solving it over the space of accelerator designs is challenging due to the large number of infeasible points, the need to handle explicit design constraints, and the difficulty in navigating the non-smooth landscape (See Figure and Figure in the Appendix) of the objective function.\nWhat makes optimization over accelerators challenging? Compared to other domains where model-based optimization methods have been applied, optimizing accelerators introduces a number of practical challenges. First, accelerator design spaces typically feature a narrow manifold of feasible accelerators within a sea of infeasible points, as visualized in Figure and Appendix (Figure). While some of these infeasible points can be identified via simple rules (e.g. estimating chip area usage), most infeasible points correspond to failures during compilation or hardware simulation. These infeasible points are generally not straightforward to formulate into the optimization problem and requires simulation.\nSecond, the optimization objective can exhibit high sensitivity to small variations in some architecture parameters (Figure) in some regions of the design space, but remain relatively insensitive in other parts, resulting in a complex optimization landscape. This suggests that optimization algorithms based on local parameter updates (e.g., gradient ascent, evolutionary schemes, etc.) may have a challenging task traversing the nearly flat landscape of the objective, which can lead to poor performance. Training dataset. We used an offline dataset D of (accelerator parameters, latency) via random sampling from the space of 452M possible accelerator configurations. Our method is only provided with a relatively modest set of feasible points (≤ 8000 points) for training, and these points are the worst-performing feasible points across the pool of randomly sampled data. This dataset is meant to reflect an easily obtainable and an application-agnostic dataset of accelerators that could have been generated once and stored to disk, or might come from real physical experiments. We emphasize that no assumptions or domain knowledge about the application use case was made during dataset collection. Table depicts the list of target applications, evaluated in this work, includes three variations of MobileNet, three in-house industry-level models for object detection (M4, M5, M6; names redacted to prevent anonymity violation), a U-net model, and two RNN-based encoderdecoder language models. These applications span the gamut from small models, such as M6, with only 0.4 MB model parameters that demands less on-chip memory, to the medium-sized models (≥ 5 MB), such as MobileNetV3 and M4 models, and large models (≥ 19 MB), such as t-RNNs, hence requiring larger on-chip memory.\nEvaluation protocol. To compare state-of-the-art simulator-driven methods and our data-driven method, we limit the number of feasible points (costly to evaluate) that can be used by any algorithm to equal amounts. We still provide infeasible points to any method and leave it up to the optimization method to use it or not. This ensures our comparisons are fair in terms of the amount of data available to each method. However, it is worthwhile to note that in contrast to our method where worse-quality data points from small offline dataset are used, the simulator-driven methods have an inherent advantage because they can steer the query process towards the points that are more likely to be better in terms of performance. Following prior work, we evaluate each run of a method by first sampling the top n = 256 design candidates according to the algorithm's predictions, evaluating all of these under the ground truth objective function and recording the performance of the best accelerator design. The final reported results is the median of ground truth objective values across five independent runs.\nTraining dataset.

Table 2 depicts the list of target applications, evaluated in this work, includes three variations of MobileNet (Gupta & Akin, 2020; Sandler et al., 2018; Howard et al., 2019), three in-house industry-level models for object detection (M4, M5, M6; names redacted to prevent anonymity violation), a U-net model (Ronneberger et al., 2015), and two RNN-based encoderdecoder language models (Graves, 2012; He et al., 2019; Sainath et al., 2020; Li et al., 2021).

To recap, to generate the dataset, we first randomly sampled accelerators from the deign space, and evaluated them for the target application, and constituted the training set from the worst-performing feasible accelerators for the given application. Since different applications admit different feasibility criteria (differences in compilation, hardware realization, and etc.), the dataset sizes for each application are different, as the number of feasible points is different.

We refer the reviewer to section 5.2 of the paper for a complete explanation of why minimality is needed. To summarize, we wish that the estimated counterfactual maintains characteristics that are not causally related to the intervention. In many cases, that cannot be measured directly. Hence, we propose the metric CLD.",
        "evidence": "Since one cannot measure changes in all variables of a real SCM, we leverage the sparse mechanism shift (SMS) hypothesis 5 for justifying a minimality property of counterfac-4. We highlight that our setting is slightly different from baseline works where the target counterfactual classes were similar to the factual classes. e.g. Transforming MNIST digits from 2 → [3, 7] or 4 → [1, 9]. Since we are sampling target classes randomly, their metric values will look lower than in their respective papers. 5. SMS states that a \"small distribution changes tend to manifest themselves in a sparse or local way in the causal factorization, that is, they should usually not affect all factors simultaneously.\" tuals. SMS translates, in our setting, to an intervention will not change many elements of the observed data. Therefore, an important property of counterfactuals is minimality or proximity to the factual observation. We suggest here a new metric entitled counterfactual latent divergence (CLD), illustrated in Fig.(a), that estimates minimality. Note that the metrics IM1 and IM2 from Sec. 5.1 do not take minimality into account. In addition, previous work only used the mean absolute error or 1 distance in the data space for measuring minimality. However, measuring similarity at pixellevel can be challenging as an intervention might change the structure of the image whilst keeping other factors unchanged. In this case, a pixel-level comparison might not be informative about the other factors of variation.\nLatent Similarity. Therefore, we choose to measure similarity between latent representation. In addition, we want a representation that captures all factors of variation on the input data. In particular, we train a variational autoencoder (VAE) (Kingma and Welling, 2014) for recovering probabilistic latent representations that capture all factors of variation in the data. The latent spaces computed with the VAE's encoder E φ are denoted as µ i , σ i = E φ (x (1) i ), where subscript i means different samples from x (1) (t = 0). We use the Kullback-Leibler divergence (KL) divergence for measuring the distances between latents. The divergence for a given counterfactual estimation and factual observation pair (x\nF ) can, therefore, be denoted as\nRelative Measure. However, absolute similarity measures give limited information. Therefore, we leverage class information for measuring minimality whilst making sure that the counterfactual is far enough from the factual class. A relative measure is obtained by estimating the probability of sets of divergence measures between the factual observation and other data points in the dataset (formalized in the Eq. 9) to less or greater than div. In particular, we compare div with the set S class of divergence measures between the factual observation x\n(1) F and all data points x (1) in a dataset\nclass is denoted in set-builder notation 6 with:\nThe sets S CF and S F are obtained by replacing \"class\" in S class with the appropriate target class of the counterfactual and factual observation class respectively. The relative measures are: (i) P (S CF ≤ div) for comparing div with the distance between all data points of the counterfactual class and the factual image; and (ii) P (S F ≥ div) for comparing div with the distance between all other data points of the factual class and the factual image. We aim for counterfactuals with low P (S CF ≤ div), enforcing minimality, and low P (S F ≥ div), enforcing bigger distances from the factual class.\nCLD. We highlight the competing nature of the two measures P (S CF ≤ div) and P (S F ≥ div) in the counterfactual setting. For example, if the intervention is too minimal -i.e. low P (S CF ≤ div) -the counterfactual will still resemble observations from the factual class -i.e. high P (S F ≥ div). Therefore, the goal is to find the best balance between the two measures. Finally, we define the counterfactual latent divergence (CLD) metric as the LogSumExp of the two probability measures. The LogSumExp operation acts as a smooth approximation of the maximum function. It also penalizes relative peak values for any of the measures when compared to a simple summation. We denote CLD as: CLD = log (exp (P (S CF ≤ div)) + exp (P (S F ≥ div))) .\n(10)\nWe show, using the same experimental setup as in Sec. 5.1, that CLD improves counterfactual estimation when quantitatively compared with the baseline methods, as illustrated in Tab. 1.\nNote that the metrics IM1 and IM2 from Sec. 5.1 do not take minimality into account. In addition, previous work (Wachter et al., 2018; Schut et al., 2021) only used the mean absolute error or `1 distance in the data space for measuring minimality. However, measuring similarity at pixellevel can be challenging as an intervention might change the structure of the image whilst keeping other factors unchanged.

All sentences in SKE Dataset are extracted from Baidu Baike and Baidu News Feeds. The dataset is divided into a training set (170k sentences), a development set (20k sentences) and a testing set (20k sentences). The training set and the development set are to be used for training and are available for free download. The test set is divided into two parts, the test set 1 is available for self-verification, the test set 2 is released one week before the end of the competition and used for the final evaluation.\nThe max sequence length is set to 128, the number of fully connected layer of relation classification branch is set to 2, and that of global relation branch is set to 1. During training, we use Adam with the learning rate of 2e-5, dropout probability of 0.1. This model converges in 3 epoch.\nAll uppercase letters are converted to lowercase letters. We use max sequence length 128 so sentences longer than 128 are split by punctuation. According to FAQ, entities in book title mark should be completely extracted. Because the annotation criteria in trainset are diverse, we revise the incomplete entities. To keep consistence, book title marks around the entities are removed.\nOur postprocessing mechanism is mainly based on the FAQ evaluation rules. After model prediction, we remove triplets whose entity-relation types are against the given schemas. For entities contained in book title mark, we complement them if they are incomplete. Date type entities are also complemented to the finest grain. These are implemented by regular expression matching.\nNote that entity related preprocessing and postprocessing are also performed on the development set to keep consistency with the test set, thus the change of development metric is reliable.\nWe evaluate our method on the SKE dataset used in this competition, which is the largest schema-based Chinese information extraction dataset in the industry, containing more than 430,000 SPO triples in over 210,000 real-world Chinese sentences, bounded by a pre-specified schema with 50 types of predicates.",

Similar to a file system, at any moment new documents could be added and/or some of the current documents could be revised. The revision operations we used were deletion, addition and replacement of words, sentences, paragraphs, section names and document titles. The addition of words, ..., section names, and new documents were pulled from the Wikipedia abstracts. This corpus generation process had five time periods INLINEFORM0 . Figure FIGREF42 illustrates this simulation. We set a Poisson distribution with rate INLINEFORM1 (the number of documents in the initial corpus) to control the number of new documents added in each time period, and a Poisson distribution with rate INLINEFORM2 to control the number of documents revised in each time period.\nWe generated six data sets using different random seeds, and each data set contained six corpora (Corpus 0 - 5). Table TABREF48 summarizes the first data set. In each data set, we name the initial corpus Corpus 0, and define INLINEFORM0 as the timestamp when we started this simulation process.

        "question": "Why is a refrigerator door more difficult to open than usual soon after you have closed it?",
        "evidence": "",
        "answer": "This can be explained by the difference in pressure between the outside and inside of the refrigerator. In order to understand the phenomenon, let's first break down the relationship between pressure and temperature. Warmer air has a higher pressure than cooler air, it has to do with the energy of air molecules but that is a subject for another time. When you open the refrigerator door, warmer air from the surroundings, which would be at room temperature, rushes inside the refrigerator. This is because the air flows from the higher-pressure region (the room), into the lower-pressure region (inside the refrigerator). When you shut the door, the warm air that had moved inside is now actively being cooled down by the refrigerator. Remember what we said about cooler air? The pressure inside the refrigerator starts to drop. This means that warmer air at higher pressure outside the refrigerator is trying to get in and is pushing against the door, the next time you try to open the door, you need to apply an extra force to counteract that pressure that is acting on the door. So that begs the question, why is this more noticeable a short time after you shut the door versus coming back let's say, an hour later? Glad you asked! It is because the seal that keeps the warm air outside and cool air inside the refrigerator is not a perfect seal, it is not designed to be for good reason. Over time, since the seal allows the movement of air, the pressure equalizes. In the absence of that pressure differential, there is no force acting on the outside of the door forcing it shut. Fun fact, commercial refrigerators have seals designed to allow for a lot more movement of air compared to home refrigerators. Want to guess why? It is because content inside commercial refrigerators needs to be accessed a lot more frequently. If their seals were similar to home refrigerators, people would experience the extra force each time they want to get something! It is fascinating how much thought goes into designing everyday things we take for granted!",

        "answer": "A dataset that allows to study whether better sentence representations can be built when having access to corresponding images, e.g. a caption and its image, in contrast with having access to the text alone.",
        "evidence": "The success of word representations (embeddings) learned from text has motivated analogous methods to learn representations of longer sequences of text such as sentences, a fundamental step on any task requiring some level of text understanding BIBREF0 . Sentence representation is a challenging task that has to consider aspects such as compositionality, phrase similarity, negation, etc. In order to evaluate sentence representations, intermediate tasks such as Semantic Textual Similarity (STS) BIBREF1 or Natural Language Inference (NLI) BIBREF2 have been proposed, with STS being popular among unsupervised approaches. Through a set of campaigns, STS has produced several manually annotated datasets, where annotators measure the similarity among sentences, with higher scores for more similar sentences, ranging between 0 (no similarity) to 5 (semantic equivalence). Human annotators exhibit high inter-tagger correlation in this task.\nIn another strand of related work, tasks that combine representations of multiple modalities have gained increasing attention, including image-caption retrieval, video and text alignment, caption generation, and visual question answering. A common approach is to learn image and text embeddings that share the same space so that sentence vectors are close to the representation of the images they describe BIBREF3 , BIBREF4 . BIBREF5 provides an approach that learns to align images with descriptions. Joint spaces are typically learned combining various types of deep learning networks such us recurrent networks or convolutional networks, with some attention mechanism BIBREF6 , BIBREF7 , BIBREF8 .\nThe complementarity of visual and text representations for improved language understanding have been shown also on word representations, where embeddings have been combined with visual or perceptual input to produce grounded representations of words BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 . These improved representation models have outperformed traditional text-only distributional models on a series of word similarity tasks, showing that visual information coming from images is complementary to textual information.\nIn this paper we present Visual Semantic Textual Similarity (vSTS), a dataset which allows to study whether better sentence representations can be built when having access to corresponding images, e.g. a caption and its image, in contrast with having access to the text alone. This dataset is based on a subset of the STS benchmark BIBREF1 , more specifically, the so called STS-images subset, which contains pairs of captions. Note that the annotations are based on the textual information alone. vSTS extends the existing subset with images, and aims at being a standard dataset to test the contribution of visual information when evaluating sentence representations.\nIn addition we show that the dataset allows to explore two hypothesis: H1) whether the image representations alone are able to predict caption similarity; H2) whether a combination of image and text representations allow to improve the text-only results on this similarity task.\nIn this paper we present Visual Semantic Textual Similarity (vSTS), a dataset which allows to study whether better sentence representations can be built when having access to corresponding images, e.g. a caption and its image, in contrast with having access to the text alone.",

        "answer": "VULGAR (VLG): Vulgar tweets are offensive tweets that contain profanity, such as mentions of private parts or sexual-related acts or references.",
        "evidence": "We developed the annotation guidelines jointly with an experienced annotator, who is a native Arabic speaker with a good knowledge of various Arabic dialects. We made sure that our guidelines were compatible with those of OffensEval2019. The annotator carried out all annotation. Tweets were given one or more of the following four labels: offensive, vulgar, hate speech, or clean. Since the offensive label covers both vulgar and hate speech and vulgarity and hate speech are not mutually exclusive, a tweet can be just offensive or offensive and vulgar and/or hate speech. The annotation adhered to the following guidelines:\nOffensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as:\nDirect threats or incitement, ex: احرقوا> مقرات المعارضة> (“AHrqwA mqrAt AlmEArDp” – “burn the headquarters of the opposition”) and هذا المنافق يجب قتله> (“h*A AlmnAfq yjb qtlh” – “this hypocrite needs to be killed”).\nInsults and expressions of contempt, which include: Animal analogy, ex: يا كلب> (“yA klb” – “O dog”) and كل تبن> (“kl tbn” – “eat hay”).; Insult to family members, ex: يا روح أمك> (“yA rwH Amk” – “O mother's soul”); Sexually-related insults, ex: يا ديوث> (“yA dywv” – “O person without envy”); Damnation, ex: الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”); and Attacks on morals and ethics, ex: يا كاذب> (“yA kA*b” – “O liar”)\nVulgar tweets are a subset of offensive tweets and contain profanity, such as mentions of private parts or sexual-related acts or references.\nHate speech tweets, a subset of offensive tweets containing offensive language targeting group based on common characteristics such as: Race, ex: يا زنجي> (“yA znjy” – “O negro”); Ethnicity, ex. الفرس الأنجاس> (“Alfrs AlAnjAs” – “Impure Persians”); Group or party, ex: أبوك شيوعي> (“Abwk $ywEy” – “your father is communist”); and Religion, ex: دينك القذر> (“dynk Alq*r” – “your filthy religion”).\nClean tweets do not contain vulgar or offensive language. We noticed that some tweets have some offensive words, but the whole tweet should not be considered as offensive due to the intention of users. This suggests that normal string match without considering contexts will fail in some cases. Examples of such ambiguous cases include: Humor, ex: يا عدوة الفرحة ههه> (“yA Edwp AlfrHp hhh” – “O enemy of happiness hahaha”); Advice, ex: لا تقل لصاحبك يا خنزير> (“lA tql lSAHbk yA xnzyr” – “don't say to your friend: You are a pig”); Condition, ex: إذا عارضتهم يقولون يا عميل> (“A*A EArDthm yqwlwn yA Emyl” – “if you disagree with them they will say: You are an agent”); Condemnation, ex: لماذا نسب بقول: يا بقرة؟> (“lmA*A nsb bqwl: yA bqrp?” – “Why do we insult others by saying: O cow?”); Self offense, ex: تعبت من لساني القذر> (“tEbt mn lsAny Alq*r” – “I am tired of my dirty tongue”); Non-human target, ex: يا بنت المجنونة يا كورة> (“yA bnt Almjnwnp yA kwrp” – “O daughter of the crazy one O football”); and Quotation from a movies or a story, ex: تاني يا زكي! تاني يا فاشل> (“tAny yA zky! tAny yA fA$l” – “again O Zaky! again O loser”). For other ambiguous cases, the annotator searched Twitter to find how actual users used expressions.\nTable TABREF11 shows the distribution of the annotated tweets. There are 1,915 offensive tweets, including 225 vulgar tweet and 506 hate speech tweets, and 8,085 clean tweets. To validate the quality of annotation, a random sample of 100 tweets from the data, containing 50 offensive and 50 clean tweets, was given to additional three annotators. We calculated the Inter-Annotator Agreement between the annotators using Fleiss’s Kappa coefficient BIBREF23. The Kappa score was 0.92 indicating high quality annotation and agreement.\nVULGAR (VLG): Vulgar tweets are offensive tweets that contain profanity, such as mentions of private parts or sexual-related acts or references.",

        "evidence": "Natural language generation (NLG) has been one of the key topics of research in natural language processing, which was highlighted by the huge body of work on NLG surveyed in BIBREF0, BIBREF1. With the advances of several devices capable of understanding spoken language and conducting conversation with human (e.g., Google Home, Amazon Echo) and the shrinking gap created by the digital devices, it is not difficult to foresee that the market and application areas of NLG systems will continue to grow, especially in applications whose users are non-experts. In such application, a user often asks for certain information and waits for the answer and a NLG module would return the answer in spoken language instead of text such as in question-answering systems or recommendation systems. The NLG system in these two applications uses templates to generate the answers in natural language for the users. A more advanced NLG system in this direction is described in BIBREF2, which works with ontologies annotated using the Attempto language and can generate a natural language description for workflows created by the systems built in the Phylotastic project. The applications targeted by these systems are significantly different from NLG systems, whose main purpose is to generate high-quality natural language description of objects or reports, such as those reported in the recent AAAI conference BIBREF3, BIBREF4, BIBREF5.\nThe present paper is motivated by the need to generate natural language description of computational results to non-expert users such as those developed in the Phylotastic project. In this project, the users are experts in evolutionary biology but are none experts in ontologies and web services. When a user places a request, he/she will receive a workflow consisting of web services, whose inputs and outputs are specified by instances of classes in the ontologies working with web services, as well as the ordering and relationships between the services. To assist the user in understanding the workflow, a natural language description of the workflow is generated. In order to accomplish the task, the NLG system in the Phylotastic project proposes to annotate elements of the ontologies using Attempto, a simple subset of English with precisely defined syntax and semantics.\nIn this paper, we propose a system that addresses the limitation of the system discussed in the Phylotastic project BIBREF2. Specifically, we assume that the annotations given in an ontology are natural language sentences. This is a reasonable assumption given that the developers of an ontology are usually those who have intimate knowledge about entities described in the ontology and often have some sort of comments about classes, objects, and instances of the ontology. We then show that the system is very flexible and can be used for the same purpose with new ontologies.\nThe rest of the paper is organized as follows. Section SECREF2 briefly reviews the basics of Grammatical Framework (GF)BIBREF6. Section SECREF3 describes the main modules of the system. Section SECREF4 includes two use cases of the system using an available ontologies against in the context of reasoning about ontologies. Specifically, it compares with the system used in the Phylotastic project and an ontology about people. This section also contains a use case that highlights the versatility of the proposed system by addressing a challenge to create an abstract Wikipedia BIBREF7. Related works are discussed in Section SECREF5. Section SECREF6 concludes the paper.\nIn this paper, we propose a system that addresses the limitation of the system discussed in the Phylotastic project.",

However, in the specific case of the Medicine Portal, the presence of an infobox does not seem strictly related to the quality class the article belongs to (according to the manual labelling). Indeed, it is recurrent that articles, spanning all classes, have an infobox, containing a schematic synthesis of the article. In particular, pages with descriptions of diseases usually have an infobox with the medical standard code of the disease (i.e., IDC-9 and IDC-10), as in Figure 2 .\nAs done for the baseline, also the first two features of the medical model have been extracted with ad hoc Python scripts, extracting HTML structures and excerpts of the textual content within the MediaWiki tags. For their extraction of the bio-medical entities, we consider the textual part of the article only, obtained after removing the MediaWiki tags, and we apply a NLP analysis, which is presented in Section \"Bio-medical entities\" .\nWe have defined 4 upper level categories of our interest: – A anatomy: an article is about anatomy; – B biography: an article is a biography of someone or tell the history of something; – D disorder: it is about a disorder; – F first aid: it reports information for first aid or emergency contacts; – O other: none of the above.",

Linguistics and Natural Language Processing have long struggled with issues around standardization and reliability of linguistic tagging. Linguistics researchers have long developed best practices for corpus annotation BIBREF27, including recent work about using crowdworkers BIBREF28. Annotated corpus projects often release guidelines and reflections about their process. For example, the Linguistic Data Consortium's guidelines for annotation of English-language entities (version 6.6) is 72 single-spaced pages BIBREF29. A universal problem of standardization is that there are often too many standards and not enough enforcement. As BIBREF30 notes, 33-81% of linguistics/NLP papers in various venues do not even mention the name of the language being studied (usually English). A meta-research study found only 1 in 9 qualitative papers in Human-Computer Interaction reported inter-rater reliability metrics BIBREF31.\nAnother related area are meta-research and methods papers focused on identifying or preventing low-effort responses from crowdworkers — sometimes called “spam” or “random” responses, or alternatively ”fraudsters” or ”cheaters.” Rates of “self-agreement” are often used, determining if the same person labels the same item differently at a later stage. One paper BIBREF32 examined 17 crowdsourced datasets for sentiment analysis and found none had self-agreement rates (Krippendorf's alpha) above 0.8, with some lower than 0.5. Another paper recommends the self-agreement strategy in conjunction with asking crowdworkers to give a short explanation of their response, even if the response is never actually examined. BIBREF33.

The primary insight is to use a data-efficient parameter sharing scheme via mixed membership modeling, with inspiration from topic models. Mixed membership models provide a flexible yet efficient latent representation, in which entities are associated with shared, global representations, but to uniquely varying degrees. I identify the skip-gram word2vec model of BIBREF0 , BIBREF1 as corresponding to a certain naive Bayes topic model, which leads to mixed membership extensions, allowing the use of fewer vectors than words. I show that this leads to better modeling performance without big data, as measured by predictive performance (when the context is leveraged for prediction), as well as to interpretable latent representations that are highly valuable for computational social science applications. The interpretability of the representations arises from defining embeddings for words (and hence, documents) in terms of embeddings for topics. My experiments also shed light on the relative merits of training embeddings on generic big data corpora versus domain-specific data.\nI tested the performance of the representations as features for document categorization and regression tasks. The results are given in Table TABREF26 . For document categorization, I used three standard benchmark datasets: 20 Newsgroups (19,997 newsgroup posts), Reuters-150 newswire articles (15,500 articles and 150 classes), and Ohsumed medical abstracts on 23 cardiovascular diseases (20,000 articles). I held out 4,000 test documents for 20 Newsgroups, and used the standard train/test splits from the literature in the other corpora (e.g. for Ohsumed, 50% of documents were assigned to training and to test sets). I obtained document embeddings for the MMSG, in the same latent space as the topic embeddings, by summing the posterior mean vectors INLINEFORM0 for each token. Vector addition was similarly used to construct document vectors for the other embedding models. All vectors were normalized to unit length. I also considered a tf-idf baseline. Logistic regression models were trained on the features extracted on the training set for each method.\nI also analyzed the regression task of predicting the year of a state of the Union address based on its text information. I used lasso-regularized linear regression models, evaluated via a leave-one-out cross-validation experimental setup. Root-mean-square error (RMSE) results are reported in Table TABREF26 (bottom). Unlike for the other tasks, the Google big data vectors were the best individual features in this case, outperforming the domain-specific SG and MMSG embeddings individually. On the other hand, SG+MMSG+Google performed the best overall, showing that domain-specific embeddings can improve performance even when big data embeddings are successful.

        "evidence": "In the literature, the main consensus is that the use of dense word embeddings outperform the sparse embeddings in many tasks. Latent semantic analysis (LSA) used to be the most popular method in generating word embeddings before the invention of the word2vec and other word vector algorithms which are mostly created by shallow neural network models. Although many studies have been employed on generating word vectors including both semantic and sentimental components, generating and analysing the effects of different types of embeddings on different tasks is an emerging field for Turkish.\nLatent Dirichlet allocation (LDA) is used in BIBREF2 to extract mixture of latent topics. However, it focusses on finding the latent topics of a document, not the word meanings themselves. In BIBREF3, LSA is utilised to generate word vectors, leveraging indirect co-occurrence statistics. These outperform the use of sparse vectors BIBREF4.\nSome of the prior studies have also taken into account the sentimental characteristics of a word when creating word vectors BIBREF5, BIBREF6, BIBREF7. A model with semantic and sentiment components is built in BIBREF8, making use of star-ratings of reviews. In BIBREF9, a sentiment lexicon is induced preferring the use of domain-specific co-occurrence statistics over the word2vec method and they outperform the latter.\nIn a recent work on sentiment analysis in Turkish BIBREF10, they learn embeddings using Turkish social media. They use the word2vec algorithm, create several unsupervised hand-crafted features, generate document vectors and feed them as input into the support vector machines (SVM) approach. We outperform this baseline approach using more effective word embeddings and supervised hand-crafted features.\nIn English, much of the recent work on learning sentiment-specific embeddings relies only on distant supervision. In BIBREF11, emojis are used as features and a bi-LSTM (bidirectional long short-term memory) neural network model is built to learn sentiment-aware word embeddings. In BIBREF12, a neural network that learns word embeddings is built by using contextual information about the data and supervised scores of the words. This work captures the supervised information by utilising emoticons as features. Most of our approaches do not rely on a neural network model in learning embeddings. However, they produce state-of-the-art results.\nIn a recent work on sentiment analysis in Turkish [11], they learn embeddings using Turkish social media.

        "evidence": "Automatic quality evaluation of Wikipedia articles has been addressed in previous works with both unsupervised and supervised learning approaches. The common idea of most of the existing work is to identify a feature set, having as a starting point the Wikipedia project guidelines, to be exploited with the objective in mind to distinguish Featured Articles. In BIBREF21 , Stvilia et al. identify a relevant set of features, including lingual, structural, historical and reputational aspects of each article. They show the effectiveness of their metrics by applying both clustering and classification. As a result, more than 90% of FA are correctly identified.\nBlumenstock BIBREF20 inspects the relevance of the word-count feature at each quality stage, showing that it can play a very important role in the quality assessment of Wikipedia articles. Only using this feature, the author achieves a F-measure of 0.902 in the task of classifying featured articles and 0.983 in the task of classifying non featured articles. The best results of the investigation are achieved with a classifier based on a neural network implemented with a multi-layer perceptron.\nIn BIBREF22 , the authors try to analyze the factors affecting the quality of Wikipedia articles, with respect to their quality class. The authors evaluate a set of 28 features, over a random sample of 500 Wikipedia articles, by weighing each metric in different stages using neural networks. Findings are that linguistic features weigh more in the lowest quality classes, and structural features, along with historical ones, become more important as the article quality improves. Their results indicate that the information quality is mainly affected by completeness, and to be “well-written\" is a basic requirement in the initial stage. Instead, reputation of authors or editors is not so important in Wikipedia because of its horizontal structure. In BIBREF23 , the authors consider the quality of the data in the infoboxes of Wikipedia, finding a correlation between the quality of information in the infobox and the article itself.\nIn BIBREF7 , the authors deal with the problem of discriminating between two large classes, namely NeedWork, GoodEnough (including in GoodEnough both GA and FA), in order to identify which articles need further revisions for being featured. They also introduce new composite features, those that we have referred to as an “actionable model” in Section \"Baseline: the actionable model\" . They obtain good classification results, with a F-measure of 0.876 in their best configuration. They also try classification for all the seven quality classes, as done in this work, using a random forest classifier with 100 trees, with a reduced set of features. The poor results (an average F-measure of 0.425) highlights the hardness of this fine-grained classification. In this paper, we address this last task in a novel way, by introducing domain features, specially dealing with the medical domain. The results of the investigation are promising.\nRecent studies specifically address the quality of medical information (in Wikipedia as well as in other resources): in BIBREF24 and BIBREF25 , the authors debate if Wikipedia is a reliable learning resource for medical students, evaluating articles on respiratory topics and cardiovascular diseases. The evaluation is carried out by exploiting DISCERN, a tool evaluating readability of articles. In BIBREF26 the authors provide novel solutions for measure the quality of medical information in Wikipedia, by adopting an unsupervised approach based on the Analytic Hierachy Process, a multi-criteria decision making technique BIBREF27 . The work in BIBREF28 aims to provide the web surfers a numerical indication of Quality of Medical Web Sites. In particular in BIBREF28 the author proposes an index to make IQ judgment of the content and of its reliability, to give the so called “surface markers” and “trust indicator”. A similar measurement is considered in BIBREF29 . where the authors present an empirical analysis that suggests the need to define genre-specific templates for quality evaluation and to develop models for an automatic genre-based classification of health information Web pages. In addition, the study shows that consumers may lack the motivation or literacy skills to evaluate the information quality of health Web pages. Clearly, this further highlights the cruciality to develop accessible automatic information quality evaluation tools and ontologies. Our work moves towards the goal, by specifically considering domain-relevant features and featuring an automatic classification task spanning over more than two classes.\nBlumenstock [6] inspects the relevance of the word-count feature at each quality stage, showing that it can play a very important role in the quality assessment of Wikipedia articles.",

        "question": "What is the sport called Cricket",
        "evidence": "",
        "answer": "Cricket is a sport first originated in Wngland. Cricket was invented by British. While cricket was primarily played starting 17th century, there have been some obscure and speculative references of sport being played in 13th century during era of King Edward II. Cricket is game played with a flat bat and a ball with each team consisting of 11 players. The goal of the game is to score as many runs as a team can score while getting their turn to bat and getting the other team out before they can reach their target. Each team can bat once and have to field while other team bats. Cricket is played in circular or oval shaped fields. The patch in the middle of the ground is called the pitch which is 22 yards in length. At each end of the pitch, three sticks are planted in the ground called stumps. Two small wooden pieces are placed on top of stumps called bails. This setup is called a wicket. Two batters from the batting team will bat on each end of the pitch. Runs are scored by hitting a ball and then running back and forth from one end of the pitch to another end. Batter can send the ball to the boundary while pitching on the ground one or more times to score 4 runs or hit the ball over the boundary without having it bounce on the ground to score 6 runs. Fielding team will place 11 of their players at various locations in the field. Person from the fielding team throwing the ball to a batter from batting team is called a bowler. Bowler’s goal is to get the batter out. Bowler will typically throw the ball on the pitch letting it bounce once on the pitch and eventually reaching a batter. There are different ways to dismiss or get a batter out. The bowler can throw the ball to a batter, induce a shot from the batter and have that ball caught directly by one of the fielder in the field. Bowler can also throw the ball toward a batter to make him or her miss and to hit the stumps or bails, thus disturbing his wicket. Bowler will deliver ball 6 times when their turn comes up. The grouping of 6 deliveries that a bowler throws to a batter is called an Over. Batters can also get run out while attempting to score a run and getting caught outside of their safe zone marked by a crease at each end of the pitch. Modern game of cricket contains many versions. These versions are called Test Cricket, One day internationals (ODI), and Twenty20. Originally, game of cricket lasted for many days. In the older version of the game , each team got a chance to bat twice and field twice taking as many days as possible to conclude the game. In modern version of the game, this mode of play called Test Cricket has been fixed to five days. So, Test cricket can last as many as five days.  One day internationals (also referred to as ODI) is a game of cricket that lasts one day. Each side gets 50 overs to bowl to another team and each side gets to bat once. Goal of a team is to score as many runs as possible in 50 overs while restricting their opposition to lesser score or getting them out completely. ODI typically lasts for 6 to 7 hours. Even more popular version of the game is called Twenty20 or T20. In this mode of the game, each team only gets 20 overs to bat and have to get their opponents out in 20 overs or to restrict them to lesser number of runs. This mode of cricket is very popular because the game only lasts for 3 hours requiring much less time of the viewers. There are many countries beside England that currently play cricket making the sport a truly global sport. The countries that play cricket are England, South Africa, Australia, India, Pakistan, Kenya, Zimbabwe, Bangladesh, New Zealand, Sri Lanka, West Indies.  The sport is also played by new entrants in the game, namely Netherlands, Ireland, Namibia, UAE, Afghanistan, USA, Canada, Papua New Guinea.",

Throughout the seven main books of the series, Harry and his friends encounter many of these creatures on their adventures in Hogwarts, the Forbidden Forest, or other locations throughout the Wizarding World. In addition, students learn to take care of creatures such as hippogriffs and unicorns in the Care of Magical Creatures class at Hogwarts. Rowling has also written Fantastic Beasts and Where to Find Them, a guide to the magical beasts found in the series, and based on the fictional textbook of the same name written by Newt Scamander and used by students at Hogwarts.\nSome creatures in the series are ordinary animals that may be imbued with magical properties or possess certain magical abilities.

        "question": "What is single-document Summarization?",
        "answer": "Single-document summarization is the task of generating a short summary for a given document.",
        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nSingle-document summarization is the task of generating a short summary for a given document.",

Contrary to Madison's proposal that the proposed amendments be incorporated into the main body of the Constitution (at the relevant articles and sections of the document), they were proposed as supplemental additions (codicils) to it.

        "answer": "4.8 points.",
        "evidence": "For the task of unsupervised dependency parse induction, we employ the Dependency Model with Valence (DMV) BIBREF2 as the syntax model in our approach. DMV is a generative model that defines a probability distribution over dependency parse trees and syntactic categories, generating tokens and dependencies in a head-outward fashion. While, traditionally, DMV is trained using gold POS tags as observed syntactic categories, in our approach, we treat each tag as a latent variable, as described in sec:general-neural.\nMost existing approaches to this task are not fully unsupervised since they rely on gold POS tags following the original experimental setup for DMV. This is partially because automatically parsing from words is difficult even when using unsupervised syntactic categories BIBREF29 . However, inducing dependencies from words alone represents a more realistic experimental condition since gold POS tags are often unavailable in practice. Previous work that has trained from words alone often requires additional linguistic constraints (like sentence internal boundaries) BIBREF29 , BIBREF30 , BIBREF31 , BIBREF32 , acoustic cues BIBREF33 , additional training data BIBREF4 , or annotated data from related languages BIBREF34 . Our approach is naturally designed to train on word embeddings directly, thus we attempt to induce dependencies without using gold POS tags or other extra linguistic information.\nLike previous work we use sections 02-21 of WSJ corpus as training data and evaluate on section 23, we remove punctuations and train the models on sentences of length INLINEFORM0 , “head-percolation” rules BIBREF39 are applied to obtain gold dependencies for evaluation. We train basic DMV, extended DMV (E-DMV) BIBREF35 and Gaussian DMV (which treats POS tag as unknown latent variables and generates observed word embeddings directly conditioned on them following Gaussian distribution) as baselines. Basic DMV and E-DMV are trained with Viterbi EM BIBREF40 on unsupervised POS tags induced from our Markov-structured model described in sec:pos. Multinomial parameters of the syntax model in both Gaussian DMV and our model are initialized with the pre-trained DMV baseline. Other parameters are initialized in the same way as in the POS tagging experiment. The directed dependency accuracy (DDA) is used for evaluation and we report accuracy on sentences of length INLINEFORM1 and all lengths. We train the parser until training data likelihood converges, and report the mean and standard deviation over 20 random restarts.\nOur model directly observes word embeddings and does not require gold POS tags during training. Thus, results from related work trained on gold tags are not directly comparable. However, to measure how these systems might perform without gold tags, we run three recent state-of-the-art systems in our experimental setting: UR-A E-DMV BIBREF36 , Neural E-DMV BIBREF11 , and CRF Autoencoder (CRFAE) BIBREF37 . We use unsupervised POS tags (induced from our Markov-structured model) in place of gold tags. We also train basic DMV on gold tags and include several state-of-the-art results on gold tags as reference points.\nAs shown in Table TABREF39 , our approach is able to improve over the Gaussian DMV by 4.8 points on length INLINEFORM0 and 4.8 points on all lengths, which suggests the additional latent embedding layer and neural projector are helpful. The proposed approach yields, to the best of our knowledge, state-of-the-art performance without gold POS annotation and without sentence-internal boundary information. DMV, UR-A E-DMV, Neural E-DMV, and CRFAE suffer a large decrease in performance when trained on unsupervised tags – an effect also seen in previous work BIBREF29 , BIBREF34 . Since our approach induces latent POS tags jointly with dependency trees, it may be able to learn POS clusters that are more amenable to grammar induction than the unsupervised tags. We observe that CRFAE underperforms its gold-tag counterpart substantially. This may largely be a result of the model's reliance on prior linguistic rules that become unavailable when gold POS tag types are unknown. Many extensions to DMV can be considered orthogonal to our approach – they essentially focus on improving the syntax model. It is possible that incorporating these more sophisticated syntax models into our approach may lead to further improvements.\nAs shown in Table 2, our approach is able to improve over the Gaussian DMV by 4.8 points on length ≤10 and 4.8 points on all lengths, which suggests the additional latent embedding layer and neural projector are helpful.",

        "answer": "Understanding user-generated noisy social media text from Twitter is a significant task",
        "evidence": "Social media is now becoming an important real-time information source, especially during natural disasters and emergencies. It is now very common for traditional news media to frequently probe users and resort to social media platforms to obtain real-time developments of events. According to a recent survey by Pew Research Center, in 2017, more than two-thirds of Americans read some of their news on social media. Even for American people who are 50 or older, INLINEFORM0 of them report getting news from social media, which is INLINEFORM1 points higher than the number in 2016. Among all major social media sites, Twitter is most frequently used as a news source, with INLINEFORM2 of its users obtaining their news from Twitter. All these statistical facts suggest that understanding user-generated noisy social media text from Twitter is a significant task.\nIn recent years, while several tools for core natural language understanding tasks involving syntactic and semantic analysis have been developed for noisy social media text BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , there is little work on question answering or reading comprehension over social media, with the primary bottleneck being the lack of available datasets. We observe that recently proposed QA datasets usually focus on formal domains, e.g. CNN/DailyMail BIBREF4 and NewsQA BIBREF5 on news articles; SQuAD BIBREF6 and WikiMovies BIBREF7 that use Wikipedia.\nIn this paper, we propose the first large-scale dataset for QA over social media data. Rather than naively obtaining tweets from Twitter using the Twitter API which can yield irrelevant tweets with no valuable information, we restrict ourselves only to tweets which have been used by journalists in news articles thus implicitly implying that such tweets contain useful and relevant information. To obtain such relevant tweets, we crawled thousands of news articles that include tweet quotations and then employed crowd-sourcing to elicit questions and answers based on these event-aligned tweets. Table TABREF3 gives an example from our TweetQA dataset. It shows that QA over tweets raises challenges not only because of the informal nature of oral-style texts (e.g. inferring the answer from multiple short sentences, like the phrase “so young” that forms an independent sentence in the example), but also from tweet-specific expressions (such as inferring that it is “Jay Sean” feeling sad about Paul's death because he posted the tweet).\nFurthermore, we show the distinctive nature of TweetQA by comparing the collected data with traditional QA datasets collected primarily from formal domains. In particular, we demonstrate empirically that three strong neural models which achieve good performance on formal data do not generalize well to social media data, bringing out challenges to developing QA systems that work well on social media domains.\nIn summary, our contributions are:\nAll these statistical facts suggest that understanding user-generated noisy social media text from Twitter is a significant task.",

Most focus on content information and use models such as convolutional neural networks (CNN) BIBREF3 or recursive neural networks BIBREF4 . However, for user-generated posts on social media like Facebook or Twitter, there is more information that should not be ignored. On social media platforms, a user can act either as the author of a post or as a reader who expresses his or her comments about the post.\nIn this paper, we classify posts taking into account post authorship, likes, topics, and comments. In particular, users and their “likes” hold strong potential for text mining. For example, given a set of posts that are related to a specific topic, a user's likes and dislikes provide clues for stance labeling. From a user point of view, users with positive attitudes toward the issue leave positive comments on the posts with praise or even just the post's content; from a post point of view, positive posts attract users who hold positive stances. We also investigate the influence of topics: different topics are associated with different stance labeling tendencies and word usage. For example we discuss women's rights and unwanted babies on the topic of abortion, but we criticize medicine usage or crime when on the topic of marijuana BIBREF5 . Even for posts on a specific topic like nuclear power, a variety of arguments are raised: green energy, radiation, air pollution, and so on. As for comments, we treat them as additional text information. The arguments in the comments and the commenters (the users who leave the comments) provide hints on the post's content and further facilitate stance classification.\nIn this paper, we propose the user-topic-comment neural network (UTCNN), a deep learning model that utilizes user, topic, and comment information. We attempt to learn user and topic representations which encode user interactions and topic influences to further enhance text classification, and we also incorporate comment information. We evaluate this model on a post stance classification task on forum-style social media platforms. The contributions of this paper are as follows: 1. We propose UTCNN, a neural network for text in modern social media channels as well as legacy social media, forums, and message boards — anywhere that reveals users, their tastes, as well as their replies to posts. 2. When classifying social media post stances, we leverage users, including authors and likers. User embeddings can be generated even for users who have never posted anything. 3. We incorporate a topic model to automatically assign topics to each post in a single topic dataset. 4. We show that overall, the proposed method achieves the highest performance in all instances, and that all of the information extracted, whether users, topics, or comments, still has its contributions.\nWe propose UTCNN, a neural network for text in modern social media channels as well as legacy social media, forums, and message boards — anywhere that reveals users, their tastes, as well as their replies to posts.",

The bulk of the remaining errors were due to questions containing highly correlated words with a different class, or classes themselves being highly correlated. For example, a specific question about Weather Models discusses “environments” changing over “millions of years”, where discussions of environments and long time periods tend to be associated with questions about Locations of Fossils. Similarly, a question containing the word “evaporation” could be primarily focused on either Changes of State or the Water Cycle (cloud generation), and must rely on knowledge from the entire question text to determine the correct problem domain. We believe these associative errors are addressable technical challenges that could ultimately lead to increased performance in subsequent models.\nErrors specific to the multiple-choice domain: We observed that using both question and all multiple choice answer text produced large gains in question classification performance – for example, BERT-QC performance increases from 0.516 (question only) to 0.654 (question and all four answer candidates), an increase of 0.138 MAP. Our error analysis observed that while this substantially increases QC performance, it changes the distribution of errors made by the system.

The Buddhist concept of Karma is a natural process that operates with all our volitional actions and which does not need an external agency or power that sits in judgement.\n\nKarma in Buddhism should not be considered as moral justice, or a method of reward and punishment, that needs an external body or authority to decide whom or what should be punished and rewarded. It is believed that Gautama Buddha attained complete insight into how the process of Karma works during the night of his full enlightenment when, through the divine eye (dibbacakku), Buddha saw how other beings die and are reborn in happy and unhappy states according to their Karma.\n\nAccording to the Cula-kammavibhanga sutta of the Majima Nikava (collection of the middle length discourses of the Buddha), a young brahmin by the name of Subha had approached the Buddha and inquired as to why there was so much inequality among human beings in terms of being short-lived or long-lived, sickly or healthy, ugly or beautiful, powerful or powerless, poor or rich, low-born or high-born, ignorant or intelligent, etc. Buddha had then explained that:\n\"all living beings are the owners of their actions, heirs to their actions, they originate from their actions, they are related through their actions, they have their actions as their refuge and that it is action or Karma that distinguishes beings as inferior and superior\n\nThe word Karma in Pali, and karma in Sanskrit, means action but encompasses only actions that are intentional, volitional and willful and which will lead to consequences sooner or later. The mind (citta) by itself cannot perform or direct any mental, verbal or physical action and it is the intention, will, mental effort or volition (cetana) that directs any mental, verbal or physical action.\n\nThus the Buddha declared:\n\"Cetanaham bhikkhave kammam vadami\nCetayitva kammam karoti, kayena, vacaya, manasa\"\n\n\"It is volition that I call Karma, by volition one performs Karma through body, word or mind.\"",

        "answer": "Reducing the problem of crosslingual document representation to a monolingual setting is proposed.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nIn this paper, a novel way of reducing the problem of crosslingual document representation to a monolingual setting is proposed.",

Young white wines are clear and look like water, while older wines that have been aged in oak get a gold tint. Young red wines are vivid purplish red while older wines have brownish tones. \nSwirl the wine - Swirling the wine helps to expose the wine to more oxygen and release its aroma, this is called as aerating the wine. Watch how the wine runs down the glass. If the streaks of wine are thick and run relatively slow the wine has more sugar or alcohol. If the wine is thin and runs down the glass fast it has less alcohol. \nSmell the wine - After you swirl the wine take a sniff and it will smell much more vibrant. There are three types of aromas that wines have: primary are  fruity or floral, secondary ones come from aging in the barrels and tertiary are aging signs.\nSip the wine - Take a sip of the wine and spread it around your mouth to detect the different type of taste it provides. The tip of the tongue will give you the sweetness while the sides give you a good indication of sourness or acidity. \nSavor the wine- How does the wine feel after. Does it leave a bitterness or leathery feel on your tongue, it means the wine has more tannins.Does the wine feel light or dense , will give you a sense of whether it is light or medium bodied. \n\nAfter you have gone through the steps the most important thing is if you liked the wine.

        "evidence": "Heterogeneous treatment effect (HTE) estimation has been of growing interest for decision-makers in a wide spectrum of contexts. It uncovers the effect of interventions at sub-group levels, thereby providing highly tailored suggestions rather than a one-size-fits-all policy. When it comes to precision medicine, HTE provides the leveraged information that physicians need to precisely treat different patients with proper dosages of drugs depending on their genes, living habits, and EHR history. Recently, with the emerging big data that exhibits astronomical complexities, HTE has been essential for online marketplaces. For largescale data that presents a huge challenge, algorithms that adapt the booming machine learning (ML) techniques to HTE estimation are proposed. However, these methods largely focus on binary or discrete treatments and thereby being not widely applicable, given the fact that continuous treatments are prevalent in practice. Examples include targeting customers with continuous incentives, customizing the duration of ads to improve user engagement, and design optimal interest rates to maximize revenue while control for default.\nFor HTE estimation with continuous treatments, it could be feasible to discretize the treatments and utilize the above approaches, but the limitations are two-phase and bring non-trivial challenges to researchers. First, ordinal treatments like different levels of education cannot be treated as categorical otherwise the order information across treatments will be lost, and secondly, discretizing or bucketing has the limitations of model inaccuracy and cannot recognize the right patterns of the outcome across treatments. To elucidate the complex relationship between treatment and outcome, researchers put forward ideas of dose-response function (DRF).\nThe estimation of DRF in the presence of high dimensional features can be viewed as a natural extension of regression problems with additional complexities. The success of random forest (RF) for regression problems motivates the development of causal forest (CF) and orthogonal random forest and the modification of Bayesian Additive Random Forest. These methods partition the feature space with a splitting criterion fitted on treatments that can provide accurate estimations for HTE. But often they posit linear or partially linear models of DRF which are vulnerable to model misspecifications. Figure is an illustration of model misspecification of random forest and CF. Doubly Robust estimators (DREs) allows for misspecification of either the treatment or outcome regression. Recent work combines the estimation of generalized propensity score with regression models of the outcome that can further reduce the bias and use kernel regression for non-parametric estimation of DRF. However, it may suffer from the curse of dimensionality when the feature space is high-dimensional given large-scale instances. To advance, provide kernel-based DML estimators that can easily deal with high-dimensional data. Nevertheless, the localization and weighting mechanism of CF is not taken into account, which is essential for capturing heterogeneity. It remains unexplored that how to effectively combine ML methods with localized estimations under no model assumptions.\nIn this paper, we propose generalized causal forest (GCF) by extending CF to a generalized one with a brand new splitting criterion, and herein the generalization is two-fold. First, we generalize the local linear model of CF to a non-parametric one with DRF. Meanwhile, we employ the distance metrics in the functional space of Partial DRF as the splitting criterion and use kernel-based DML estimators as the DRF approximation.\nWhen it comes to implementations, many open source packages integrate recent research with the trending ML methods that facilitate HTE estimation, such as EconML, CausalML and GRF. EconML, CausalML offer a suite of high-performance ML algorithms like DML, while GRF specially supports CF. However, they are only compatible with single-machine systems and may not be efficient when it comes to large-scale instances. Apache Spark is integrated for handling large-scale data with distributed and in-memory computing, while inclusively provides APIs of trending ML algorithms with the built-in MLlib. Therefore, as one of our contributions, we build our algorithm on Spark that enables large-scale data processing and easy use of any ML techniques. To summarize, the main contributions are:\n• We are the first to generalize CF's partially linear model to a non-parametric one with DRF and apply kernel-based DML estimators. The proposed algorithm pictures the nonparametric behaviors of how outcome varies with treatments. • We propose a distance-based splitting criterion with various distance metrics in the functional space of Partial DRF that generalizes the differences of CAPE in CF. • Our proposed GCF has been tested on both synthetic and large-scale real-world datasets. It improves on SOTA in terms of multiple evaluation metrics. We implement GCF on Apache Spark MLlib and achieves higher computatinal efficiency by distributed computing.\nThe rest of the paper is organized as follows. In Section 2, we present related works in the literature.\nIn Section 3, we introduce some notations and backgrounds. In Section 4, we introduce the Generalized Causal Forest. In Section 5, we examine the empirical performance of GCF by applying it to both synthetic and real-world data sets. We conclude the paper with some discussions in Section 6.\nIn this paper, we propose generalized causal forest (GCF) by extending CF to a generalized one with a brand new splitting criterion, and herein the generalization is two-fold.",

While BIBREF0 used Lead-3 as an extractive baseline, in our data sentence order doesn't matter as reflections are independent. We thus use a similar in concept baseline: randomly select N reflections. Since the baseline is random we report the average result of 100 runs. Following BIBREF5, we compare results to MEAD BIBREF20 and to BIBREF5's extractive phrase-based model. Since these models extracted 5 phrases as extractive summary, we use N=5 for our three extractive baselines. Additionally we compare to running only the extractive part of Fast-RL.\nDomain Transfer (for testing H2, H5).\nTo observe the impact of using out-of-domain (news) data for pretraining to compensate for low resource in-domain (reflection) data, we train 3 variants of PG-net: model training on CNN/DM; model training on reflections; and model training on CNN/DM then tuning using reflections. Table TABREF11 shows example summaries generated by the three variants of PG-net for a CS document. For all experiments where reflections are used for training/tuning, we train using a leave one course out approach (i.e, in each fold, three courses are used for training and the remaining course for testing). If the experiment involves tuning a combined dictionary of CNN/DM and reflections is used to avoid domain mismatch. To tune model parameters, the best number of steps for training, the learning rate, etc., a randomly selected 50% of the training data is used for validation. We choose the parameters that maximize ROUGE scores over this validation set.\nTo implement PG-net we use OpenNMT BIBREF21 with the original set of parameters. The out-of-domain model is trained for 100k steps using the CNN/DM dataset. Following base model training, we tune the model by training it using student reflections. The tuning is done by lowering the LR from 0.15 to 0.1 and training the model for additional 500 steps. The in-domain model is trained only using reflections. We use the same model architecture as above and train the model for 20k steps using adagrad and LR of 0.15.\nSynthesis Baseline (for testing H3, H4). Following BIBREF12, we developed a data synthesis baseline using word replacement via WordNet. The baseline iterates over all words in a summary. If word $X$ has $N$ synonyms in WordNet, the model creates $N$ new versions of the summary and corresponding reflections by replacing the word $X$ with each of the $N$ synonyms.\nTemplate Synthesis Model (for testing H4, H5). To synthesize summaries, we use the same leave one course out approach. For each course, we use the data from the other three courses to train the rewriting module and tune the scoring language model. We can also use the summaries from CNN/DM data as additional samples to further train the rewriting module. We then start synthesizing data using that training data as input. First templates are constructed. The templates are then clustered into 8 clusters. We decided to use 8 to avoid clustering templates from POI with MP, as the templates from both prompts would contain very different supporting words. We also wanted to avoid a high level of dissimilarity within each cluster, and allow some diversity. Following the clustering, the rewriting model produces candidate summaries for each human summary. The rewriting model is another PG-net with the same exact parameters. After producing the candidate summaries, a language model is used to score them. The language model is a single layer LSTM language model trained on 36K sentences from Wikipedia and fine tuned using student reflections. In this work we decided to pick only the highest 3 scored candidate summaries as synthetic data, to avoid adding ill-formed summaries to the training data. Since we are adding $N$ synthetic summaries for each set of reflections, that means we are essentially duplicating the size of our original reflection training data by $N$, which is 3 in our case. Table TABREF11 shows a human summary, the keywords extracted, then the output of injecting keywords in a different template using rewriting.\nTemplate-based Summarization (for testing H6). While the proposed template-based model was intended for data synthesis, with minor modification it can be adapted for summarization itself. Because the modifications introduce few parameters, the model is suitable for small datasets. Recall that for data synthesis, the input to the template method is a summary. Since for summarization the input instead is a set of reflections, we perform keyword extraction over the set of reflections. We then add an extra logistic regression classifier that uses the set of reflections as input and predicts a cluster of templates constructed from other courses. Using the keywords and the predicted cluster of templates, we use the same rewriting model to produce candidate summaries. The last step in the pipeline is scoring. In data synthesis, a reference summary is used for scoring; however, in summarization we don't have such a reference. To score the candidate summaries, the model only uses the language model and produces the candidate with the highest score.\nTo observe the impact of using out-of-domain (news) data for pretraining to compensate for low resource in-domain (reflection) data, we train 3 variants of PG-net: model training on CNN/DM; model training on reflections; and model training on CNN/DM then tuning using reflections.",

Here, we consider the problem of estimating the level of controversiality associated with a given Wikipedia concept (title). We demonstrate that the textual contexts in which the concept is referenced can be leveraged to facilitate this.\nThe definition of which concepts are controversial is controversial by itself; an accurate definition of this elusive notion attracted the attention of researchers from various fields, see for example some recent attempts in BIBREF0, BIBREF1, BIBREF2.\nMost people would agree, for example, that Global warming is a controversial concept, whereas Summer is not. However, the concept Pollution may be seen as neutral by some, yet controversial by others, who associate it with environmental debates. In other words, different people may have different opinions, potentially driven by different contexts salient in their mind. Yet, as reported in the sequel, an appreciable level of agreement can be reached, even without explicit context.\nFocusing here on Wikipedia concepts, we adopt as an initial “ground truth” the titles listed on the Wikipedia list of controversial issues, which is curated based on so-called “edit wars”. We then manually annotate a set of Wikipedia titles which are locked for editing, and evaluate our system on this much larger and more challenging dataset.\nTo estimate the level of controversy associated with a Wikipedia concept, we propose to simply examine the words in the sentences in which the concept is referenced. Because a concept can often be found in multiple contexts, the estimation can be seen as reflecting the “general opinion” about it in the corpus. This contrasts previous works, which consider this a binary problem, and employ a complex combination of features extracted from Wikipedia's article contents and inter-references, and more extensively – from the rich edit history thereof.\nHere, we consider the problem of estimating the level of controversiality associated with a given Wikipedia concept (title).",

Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing.

Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nWe differentiate from the previous works as follows: i) instead of n-gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them4 ; and iii) in contrast to the Twitter dataset of [6], we will make available our dataset to the research community.",

In a controlled experiment where we aim to remove the influence of frequency biases, we degrade the source sentences by masking words through three strategies to replace words by a placeholder: random source words, ambiguous source words and gender unmarked source words. The procedure is applied to the train, validation and test sets. For the resulting dataset generated for each setting, we compare models having access to text-only context versus additional text and multimodal contexts. We seek to get insights into the contribution of each type of context to address each type of degradation.\nIn this setting (RND) we simulate erroneous source words by randomly dropping source content words. We first tag the entire source sentences using the spacy toolkit BIBREF26 and then drop nouns, verbs, adjectives and adverbs and replace these with a default BLANK token. By focusing on content words, we differ from previous work that suggests that neural machine translation is robust to non-content word noise in the source BIBREF27 .\nIn this setting (AMB), we rely on the MLT dataset BIBREF11 which provides a list of source words with multiple translations in the Multi30k training set. We replace ambiguous words with the BLANK token in the source language, which results in two language-specific datasets.\nIn this setting (PERS), we use the Flickr Entities dataset BIBREF28 to identify all the words that were annotated by humans as corresponding to the category person. We then replace such source words with the BLANK token.\nThe statistics of the resulting datasets for the three degradation strategies are shown in Table TABREF10 .

The encoder-decoder-reconstructor BIBREF3 requires slightly longer time to train than the baseline NMT, but we emphasize that decoding time remains the same with the encoder-decoder-reconstructor and baseline-NMT. The results show that the encoder-decoder-reconstructor BIBREF3 significantly improves translation accuracy by 1.01 points on ASPEC and 1.37 points on NTCIR in English-Japanese translation ( INLINEFORM1 ). However, it does not significantly improve translation accuracy in Japanese-English translation. In addition, it is proved that the encoder-decoder-reconstructor without pre-training worsens rather than improves translation accuracy.\nTable TABREF24 shows examples of outputs of English-Japanese translations. In Example 1, “UTF8min乱 流 粘性 と 数値 粘性 の 大小 関係 により ,” (on the basis of the relation between turbulent viscosity and numerical viscosity in size) is missing in the output of baseline-NMT, but “UTF8min乱 流 粘性 と 数値 的 粘性 の 関係 を 基 に” (on the basis of the relation between turbulent viscosity and numerical viscosity) is present in the output of encoder-decoder-reconstructor. In Example 2, “UTF8min新生児” (newborn infant) and “UTF8min30歳以上の” (of 30 ‐ year ‐ old or more) are repeated in the output of baseline-NMT, but they appear only once in the output of encoder-decoder-reconstructor.\nIn addition, Figures FIGREF25 and FIGREF25 show the attention layer on baseline-NMT and encoder-decoder-reconstructor in each example. In Figure FIGREF25 , although the attention layer of baseline NMT attends input word “turbulent”, the decoder does not output “UTF8min乱流” (turbulent) but “UTF8min検討” (examined) at the 13th word. Thus, under-translation may be resulted from the hidden layer or the embedding layer instead of the attention layer. In Figure FIGREF25 , it is found that the attention layer of baseline-NMT repeatedly attends input words “newborn infant” and “30 ‐ year ‐ old or more”. Consequently, the decoder repeatedly outputs “UTF8min新生児” (newborn infant) and “UTF8min30歳以上の” (of 30 ‐ year ‐ old or more). On the other hand, the attention layer of encoder-decoder-reconstructor almost correctly attends input words.\nTable TABREF28 shows a comparison of the number of word occurrences for each corpus and model. The columns show (i) the number of words that appear more frequently than the counterparts in the reference, and (ii) the number of words that appear more than once but are not included in the reference. Note that these numbers do not include unknown words, so (iii) shows the number of unknown words. In all the cases, the number of occurrence of redundant words is reduced in encoder-decoder-reconstructor. Thus, we confirmed that encoder-decoder-reconstructor achieves reduction of repeating and missing words while maintaining the quality of translation.\nThe results show that the encoder-decoder-reconstructor significantly improves translation accuracy by 1.01 points on ASPEC and 1.37 points on NTCIR in English-Japanese translation (p < 0.05).

        "question": "How to filter the redundant tweets in this paper?",
        "answer": "The redundant tweets were filtered based on the cosine similarity score.",
        "evidence": "We aimed to mimic the presence of sparse/noisy content distribution, mandating the need to curate a novel dataset via specific lexicons. We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation. With increasing the number of iterations, the pool of seed phrases gets refined and augments the selection of transport relevant tweets. The proposed pipeline is tailored to identify complaint relevant tweets in a noisy scenario.\nThe redundant tweets were filtered based on the cosine similarity score.",

        "answer": "Because the emergence of seq2seq models and attention mechanisms.",
        "evidence": "Abstractive Summarization. Abstractive summarization aims to generate coherent summaries with high readability, and has seen increasing interest and improved performance due to the emergence of seq2seq models BIBREF8 and attention mechanisms BIBREF9. For example, BIBREF0, BIBREF2, and BIBREF1 in addition to using encoder-decoder model with attention, they used pointer networks to solve the out of vocabulary issue, while BIBREF0 used coverage mechanism to solve the problem of word repetition. In addition, BIBREF2 and BIBREF10 used reinforcement learning in an end-to-end setting.\nTo our knowledge, training such neural abstractive summarization models in low resource domains using domain transfer has not been thoroughly explored on domains different than news. For example, BIBREF4 reported the results of training on CNN/DM data while evaluating on DUC data without any tuning. Note that these two datasets are both in the news domain, and both consist of well written, structured documents. The domain transfer experiments of BIBREF1 similarly used two different news summarization datasets (CNN/DM and NYT). Our work differs in several ways from these two prior domain transfer efforts. First, our experiments involve two entirely different domains: news and student reflections. Unlike news, student reflection documents lack global structure, are repetitive, and contain many sentence fragments and grammatical mistakes. Second, the prior approaches either trained a part of the model using NYT data while retaining the other part of the model trained only on CNN/DM data BIBREF1, or didn't perform any tuning at all BIBREF4. In contrast, we do the training in two consecutive phases, pretraining and fine tuning. Finally, BIBREF1 reported that while training with domain transfer outperformed training only on out-of-domain data, it was not able to beat training only on in-domain data. This is likely because their in and out-of-domain data sizes are comparable, unlike in our case of scarce in-domain data.\nIn a different approach to abstractive summarization, BIBREF11 developed a soft template based neural method consisting of an end-to-end deep model for template retrieval, reranking and summary rewriting. While we also develop a template based model, our work differs in both model structure and purpose.\nData Synthesis. Data synthesis for text summarization is underexplored, with most prior work focusing on machine translation, and text normalization. BIBREF12 proposed doing data augmentation through word replacement, using WordNet BIBREF13 and vector space similarity, respectively. We will use a WordNet replacement method as a baseline synthesis method in the experiments described below. In contrast, BIBREF14 synthesized/augmented data through back-translation and word replacement using language models. BIBREF15 is another recent work that was done in parallel and is very close to ours. However, in addition to the difference in both our and their model, we think it might be infeasible to back generate student reflections from a human summary, especially an abstractive one.\nAbstractive summarization aims to generate coherent summaries with high readability, and has seen increasing interest and improved performance due to the emergence of seq2seq models (Sutskever, Vinyals, and Le 2014) and attention mechanisms (Bahdanau, Cho, and Bengio 2014).",

The task is to generate an inflected word form given its lemma and the context in which it occurs.\nMorphological (re)inflection from context is of particular relevance to the field of computational linguistics: it is compelling to estimate how well a machine-learned system can capture the morphosyntactic properties of a word given its context, and map those properties to the correct surface form for a given lemma.\nThere are two tracks of Task 2 of CoNLL–SIGMORPHON 2018: in Track 1 the context is given in terms of word forms, lemmas and morphosyntactic descriptions (MSD); in Track 2 only word forms are available. See Table TABREF1 for an example. Task 2 is additionally split in three settings based on data size: high, medium and low, with high-resource datasets consisting of up to 70K instances per language, and low-resource datasets consisting of only about 1K instances.\nThe baseline provided by the shared task organisers is a seq2seq model with attention (similar to the winning system for reinflection in CoNLL–SIGMORPHON 2016, BIBREF1 ), which receives information about context through an embedding of the two words immediately adjacent to the target form. We use this baseline implementation as a starting point and achieve the best overall accuracy of 49.87 on Task 2 by introducing three augmentations to the provided baseline system: (1) We use an LSTM to encode the entire available context; (2) We employ a multi-task learning approach with the auxiliary objective of MSD prediction; and (3) We train the auxiliary component in a multilingual fashion, over sets of two to three languages.\nIn analysing the performance of our system, we found that encoding the full context improves performance considerably for all languages: 11.15 percentage points on average, although it also highly increases the variance in results. Multi-task learning, paired with multilingual training and subsequent monolingual finetuning, scored highest for five out of seven languages, improving accuracy by another 9.86% on average.\nWe use this baseline implementation as a starting point and achieve the best overall accuracy of 49.87 on Task 2 by introducing three augmentations to the provided baseline system: (1) We use an LSTM to encode the entire available context; (2) We employ a multitask learning approach with the auxiliary objective of MSD prediction; and (3) We train the auxiliary component in a multilingual fashion, over sets of two to three languages.",

        "evidence": "There are mainly three types of architectures when building conversational systems: totally rule-oriented, totally data-oriented, and a mix of rules and data-oriented.\nRule-oriented\nA rule-oriented architecture provides a manually coded reply for each recognized utterance. Classical examples of rule-based chatbots include Eliza and Parry. Eliza could also extract some words from sentences and then create another sentence with these words based on their syntatic functions. It was a rule-based solution with no reasoning. Eliza could not \"understand\" what she was parsing. More sophisticated rule-oriented architectures contain grammars and mappings for converting sentences to appropriate sentences using some sort of knowledge. They can be implemented with propositional logic or first-order logic (FOL). Propositional logic assumes the world contains facts (which refer to events, phenomena, symptoms or activities). Usually, a set of facts (statements) is not sufficient to describe a domain in a complete manner. On the other hand, FOL assumes the world contains Objects (e.g., people, houses, numbers, etc.), Relations (e.g. red, prime, brother of, part of, comes between, etc.), and Functions (e.g. father of, best friend, etc.), not only facts as in propositional logic. Moreover, FOL contains predicates, quantifiers and variables, which range over individuals (which are domain of discourse).\nProlog (from French: Programmation en Logique) was one of the first logic programming languages (created in the 1970s), and it is one of the most important languages for expressing phrases, rules and facts. A Prolog program consists of logical formulas and running a program means proving a theorem. Knowledge bases, which include rules in addition to facts, are the basis for most rule-oriented chatbots created so far.\nIn general, a rule is presented as follows: DISPLAYFORM0 \nProlog made it possible to perform the language of Horn clauses (implications with only one conclusion). The concept of Prolog is based on predicate logic, and proving theorems involves a resolute system of denials. Prolog can be distinguished from classic programming languages due to its possibility of interpreting the code in both a procedural and declarative way. Although Prolog is a set of specifications in FOL, it adopts the closed-world assumption, i.e. all knowledge of the world is present in the database. If a term is not in the database, Prolog assumes it is false.\nIn case of Prolog, the FOL-based set of specifications (formulas) together with the facts compose the knowledge base to be used by a rule-oriented chatbot. However an Ontology could be used. For instance, OntBot BIBREF27 uses mapping technique to transform ontologies and knowledge into relational database and then use that knowledge to drive its chats. One of the main issues currently facing such a huge amount of ontologies stored in a database is the lack of easy to use interfaces for data retrieval, due to the need to use special query languages or applications.\nIn rule-oriented chatbots, the degree of intelligent behavior depends on the knowledge base size and quality (which represents the information that the chatbot knows), poor ones lead to weak chatbot responses while good ones do the opposite. However, good knowledge bases may require years to be created, depending on the domain.\nData-oriented\nAs opposed to rule-oriented architectures, where rules have to be explicitly defined, data-oriented architectures are based on learning models from samples of dialogues, in order to reproduce the behavior of the interaction that are observed in the data. Such kind of learning can be done by means of machine learning approach, or by simply extracting rules from data instead of manually coding them.\nAmong the different technologies on which these system can be based, we can highlight classical information retrieval algorithms, neural networks BIBREF28 , Hidden Markov Models (HMM) BIBREF29 , and Partially Observable Markov Decision Process (POMDP) BIBREF30 . Examples include Cleverbot and Tay BIBREF31 . Tay was a chatbot developed by Microsoft that after one day live learning from interaction with teenagers on Twitter, started replying impolite utterances. Microsoft has developed others similar chatbots in China (Xiaoice) and in Japan (Rinna). Microsoft has not associated its publications with these chatbots, but they have published a data-oriented approach BIBREF32 that proposes a unified multi-turn multi-task spoken language understanding (SLU) solution capable of handling multiple context sensitive classification (intent determination) and sequence labeling (slot filling) tasks simultaneously. The proposed architecture is based on recurrent convolutional neural networks (RCNN) with shared feature layers and globally normalized sequence modeling components.\nA survey of public available corpora for can be found in BIBREF33 . A corpus can be classified into different categories, according to: the type of data, whether it is spoken dialogues, transcripts of spoken dialogues, or directly written; the type of interaction, if it is human-human or human-machine; and the domain, whether it is restricted or unconstrained. Two well-known corpora are the Switchboard dataset, which consists of transcripts of spoken, unconstrained, dialogues, and the set of tasks for the Dialog State Tracking Challenge (DSTC), which contain more constrained tasks, for instance the restaurant and travel information sets.\nRule and Data-oriented\nThe model of learning in current A.L.I.C.E. BIBREF13 is incremental or/and interactive learning because a person monitors the robot's conversations and creates new AIML content to make the responses more appropriate, accurate, believable, \"human\", or whatever he/she intends. There are algorithms for automatic detection of patterns in the dialogue data and this process provides the person with new input patterns that do not have specific replies yet, permitting a process of almost continuous supervised refinement of the bot.\nAs already mentioned, A.L.I.C.E. consists of roughly 41,000 elements called categories which is the basic unit of knowledge in AIML. Each category consists of an input question, an output answer, and an optional context. The question, or stimulus, is called the pattern. The answer, or response, is called the template. The two types of optional context are called that and topic. The keyword that refers to the robot's previous utterance. The AIML pattern language consists only of words, spaces, and the wildcard symbols \"_\" and \"*\". The words may consist only of letters and numerals. The pattern language is case invariant. Words are separated by a single space, and the wildcard characters function like words, similar to the initial pattern matching strategy of the Eliza system. More generally, AIML tags transform the reply into a mini computer program which can save data, activate other programs, give conditional responses, and recursively call the pattern matcher to insert the responses from other categories. Most AIML tags in fact belong to this template side sublanguage BIBREF13 .\nAIML language allows:\nSymbolic reduction: Reduce complex grammatical forms to simpler ones.\nDivide and conquer: Split an input into two or more subparts, and combine the responses to each.\nSynonyms: Map different ways of saying the same thing to the same reply.\nSpelling or grammar corrections: the bot both corrects the client input and acts as a language tutor.\nDetecting keywords anywhere in the input that act like triggers for a reply.\nConditionals: Certain forms of branching to produce a reply.\nAny combination of (1)-(6).\nWhen the bot chats with multiple clients, the predicates are stored relative to each client ID. For example, the markup INLINEFORM0 set name INLINEFORM1 \"name\" INLINEFORM2 Matthew INLINEFORM3 /set INLINEFORM4 stores the string Matthew under the predicate named \"name\". Subsequent activations of INLINEFORM5 get name=\"name\" INLINEFORM6 return \"Matthew\". In addition, one of the simple tricks that makes ELIZA and A.L.I.C.E. so believable is a pronoun swapping substitution. For instance:\nU: My husband would like to invest with me.\nS: Who else in your family would like to invest with you?\nThere are mainly three types of architectures when building conversational systems: totally rule-oriented, totally data-oriented, and a mix of rules and data-oriented.",

Religious hate speech appeared in only 15% of all hate speech tweets.\nNext, we analyzed all tweets labeled as offensive to better understand how Arabic speakers use offensive language. Here is a breakdown of usage:\nDirect name calling: The most frequent attack is to call a person an animal name, and the most used animals were كلب> (“klb” – “dog”), حمار> (“HmAr” – “donkey”), and بهيم> (“bhym” – “beast”). The second most common was insulting mental abilities using words such as غبي> (“gby” – “stupid”) and عبيط> (“EbyT” –“idiot”). Some culture-specific differences should be considered. Not all animal names are used as insults. For example, animals such as أسد> (“Asd” – “lion”), صقر> (“Sqr” – “falcon”), and غزال> (“gzAl” – “gazelle”) are typically used for praise. For other insults, people use: some bird names such as دجاجة> (“djAjp” – “chicken”), بومة> (“bwmp” – “owl”), and غراب> (“grAb” – “crow”); insects such as ذبابة> (“*bAbp” – “fly”), صرصور> (“SrSwr” – “cockroach”), and حشرة> (“H$rp” – “insect”); microorganisms such as جرثومة> (“jrvwmp” – “microbe”) and طحالب> (“THAlb” – “algae”); inanimate objects such as جزمة> (“jzmp” – “shoes”) and سطل> (“sTl” – “bucket”) among other usages.\nSimile and metaphor: Users use simile and metaphor were they would compare a person to: an animal as in زي الثور> (“zy Alvwr” – “like a bull”), سمعني نهيقك> (“smEny nhyqk” – “let me hear your braying”), and هز ديلك> (“hz dylk” – “wag your tail”); a person with mental or physical disability such as منغولي> (“mngwly” – “Mongolian (down-syndrome)”), معوق> (“mEwq” – “disabled”), and قزم> (“qzm” – “dwarf”); and to the opposite gender such as جيش نوال> (“jy$ nwAl” – “Nawal's army (Nawal is female name)”) and نادي زيزي> (“nAdy zyzy” – “Zizi's club (Zizi is a female pet name)”).\nIndirect speech: This type of offensive language includes: sarcasm such as أذكى إخواتك> (“A*kY AxwAtk” – “smartest one of your siblings”) and فيلسوف الحمير> (“fylswf AlHmyr” – “the donkeys' philosopher”); questions such as ايه كل الغباء ده> (“Ayh kl AlgbA dh” – “what is all this stupidity”); and indirect speech such as النقاش مع البهايم غير مثمر> (“AlnqA$ mE AlbhAym gyr mvmr” – “no use talking to cattle”).\nWishing Evil: This entails wishing death or major harm to befall someone such as ربنا ياخدك> (“rbnA yAxdk” – “May God take (kill) you”), الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”), and روح في داهية> (“rwH fy dAhyp” – equivalent to “go to hell”).\nName alteration: One common way to insult others is to change a letter or two in their names to produce new offensive words that rhyme with the original names. Some examples of such include changing الجزيرة> (“Aljzyrp” – “Aljazeera (channel)”) to الخنزيرة> (“Alxnzyrp” – “the pig”) and خلفان> (“xlfAn” – “Khalfan (person name)”) to خرفان> (“xrfAn” – “crazed”).\nSocietal stratification: Some insults are associated with: certain jobs such as بواب> (“bwAb” – “doorman”) or خادم> (“xAdm” – “servant”); and specific societal components such بدوي> (“bdwy” – “bedouin”) and فلاح> (“flAH” – “farmer”).\nImmoral behavior: These insults are associated with negative moral traits or behaviors such as حقير> (“Hqyr” – “vile”), خاين> (“xAyn” – “traitor”), and منافق> (“mnAfq” – “hypocrite”).\nSexually related: They include expressions such as خول> (“xwl” – “gay”), وسخة> (“wsxp” – “prostitute”), and عرص> (“ErS” – “pimp”).\nFigure FIGREF17 shows top words with the highest valance score for individual words in the offensive tweets. Larger fonts are used to highlight words with highest score and align as well with the categories mentioned ahead in the breakdown for the offensive languages. We modified the valence score described by BIBREF1 conover2011political to magnify its value based on frequency of occurrence. The score is computed as follows:\n$V(I) = 2 \\frac{ \\frac{tf(I, C_off)}{total(C_off)}}{\\frac{tf(I, C_off)}{total(C_off)} + \\frac{tf(I, C_cln)}{total(C_cln)} } - 1$\nwhere\n$tf(I, C_i) = \\sum _{a \\in I \\bigcap C_i} [ln(Cnt(a, C_i)) + 1]$\n$total(C_i) = \\sum _{I} tf(I, C_i)$\n$Cnt(a, C_i)$ is the number of times word $a$ was used in offensive or clean tweets tweets $C_i$. In essence, we are replacing term frequencies with the natural log of the term frequencies.\nFigure 3 shows that the vast majority of offensive tweets, including vulgar and hate speech, were authored by males.",

        "question": "What is the extremely resource constrained scenario the authors consider?",
        "answer": "An extremely resource constrained scenario, where they do not have any parallel corpus for the child task",
        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nWe consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task.",

        "evidence": "Named Entity Recognition (NER) is a foremost NLP task to label each atomic elements of a sentence into specific categories like \"PERSON\", \"LOCATION\", \"ORGANIZATION\" and othersBIBREF0. There has been an extensive NER research on English, German, Dutch and Spanish language BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, and notable research on low resource South Asian languages like HindiBIBREF6, IndonesianBIBREF7 and other Indian languages (Kannada, Malayalam, Tamil and Telugu)BIBREF8. However, there has been no study on developing neural NER for Nepali language. In this paper, we propose a neural based Nepali NER using latest state-of-the-art architecture based on grapheme-level which doesn't require any hand-crafted features and no data pre-processing.\nRecent neural architecture like BIBREF1 is used to relax the need to hand-craft the features and need to use part-of-speech tag to determine the category of the entity. However, this architecture have been studied for languages like English, and German and not been applied to languages like Nepali which is a low resource language i.e limited data set to train the model. Traditional methods like Hidden Markov Model (HMM) with rule based approachesBIBREF9,BIBREF10, and Support Vector Machine (SVM) with manual feature-engineeringBIBREF11 have been applied but they perform poor compared to neural. However, there has been no research in Nepali NER using neural network. Therefore, we created the named entity annotated dataset partly with the help of Dataturk to train a neural model. The texts used for this dataset are collected from various daily news sources from Nepal around the year 2015-2016.\nFollowing are our contributions:\nWe present a novel Named Entity Recognizer (NER) for Nepali language.

BIBREF9 ncls incorporate monolingual summarization and machine translation in the training procedure to improve cross-lingual summarization. However, the systems only conduct experiments that generate summaries with different languages from the input language, rather than transferring supervision signals across all language pairs. BIBREF10 kumar2019cross introduce a cross-lingual model for question generation, which uses training data annotated in multiple languages to jointly train a sequence-to-sequence model. In contrast, our method can also be applied to zero-shot settings across languages.\nVarious training objectives are designed to pretrain text encoders used for general-purpose language representations, such as language modeling BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15, auto-encoding BIBREF16, and machine translation BIBREF17. Apart from pre-training encoders, several pre-trained models BIBREF18, BIBREF19 are proposed for generation tasks. In comparison, our goal is to investigate a pre-training method for cross-lingual NLG tasks.\nCross-lingual pre-training aims at building universal cross-lingual encoders that can encode multilingual sentences to a shared embedding space. BIBREF20 artetxe2018massively use the sequence encoder of the multilingual translation model BIBREF3 to produce cross-lingual sentence embeddings. However, as shown in the experiments (Section SECREF4), it is difficult to control the target language by directly fine-tuning the pre-trained translation model on downstream NLG tasks. BIBREF4 xnli propose an alignment loss function to encourage parallel sentences to have similar representations. By pre-training BERT BIBREF13 on corpora of multiple languages, it shows a surprising ability to produce cross-lingual representations BIBREF21.

Each point is identified by its coordinates (x, y), where x represents a benchmark value and y is the matching value from the model.\n3. To serve as a reference, a line drawn from the equation y = x is occasionally included. Where the model accurately reproduces a benchmark, that point will fall on the line.\n4. When an author wants to visually validate a model in a paper or report, parity plots are used. On the other hand, when the data span a wide range, the big scale obscures significant differences, giving the model the appearance of being better than it actually is.

L. 73–291, 48 Stat. 881, enacted June 6, 1934, codified at 15 U.S.C. § 78a et seq.) is a law governing the secondary trading of securities (stocks, bonds, and debentures) in the United States of America. A landmark of wide-ranging legislation, the Act of '34 and related statutes form the basis of regulation of the financial markets and their participants in the United States. The 1934 Act also established the Securities and Exchange Commission (SEC), the agency primarily responsible for enforcement of United States federal securities law.\n\nCompanies raise billions of dollars by issuing securities in what is known as the primary market. Contrasted with the Securities Act of 1933, which regulates these original issues, the Securities Exchange Act of 1934 regulates the secondary trading of those securities between persons often unrelated to the issuer, frequently through brokers or dealers. Trillions of dollars are made and lost each year through trading in the secondary market.",

        "answer": "The combination of CV and NLP.",
        "evidence": "Significant progress has been made in the field of machine learning in the past years due to the rapid development of deep learning BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5. Dating back to the dramatic increase in the accuracy of large-scale automatic speech recognition (ASR) using fully connected deep neural networks (DNN) and deep auto-encoders around 2010 BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, and followed by a set of breakthroughs in computer vision (CV) using deep convolutional neural network (CNN) models BIBREF17 for large-scale image classification around 2012 BIBREF18, BIBREF19, BIBREF20, BIBREF21 and large-scale object detection BIBREF22, BIBREF23, BIBREF24 around 2014, a set of major milestones have been achieved in pattern recognition with single input modality. Subsequently, in natural language processing (NLP), recurrent neural network (RNN) based semantic slot filling methods BIBREF25 achieved new state-of-the-art in spoken language understanding, and RNN-encoder-decoder models with attention mechanism BIBREF26, also referred to as sequence to sequence models BIBREF27, produced superior performance in machine translation in an end-to-end fashion BIBREF28, BIBREF29. For other NLP tasks without much training data, such as question answering (QA) and machine reading comprehension, generative pre-training that transfers parameters from a language model (LM) pre-trained on a large out-of-domain data set using unsupervised or self learning then followed by fine-tuning on small in-domain data sets, achieved record-breaking results over a set of tasks BIBREF30, BIBREF31, BIBREF32.\nDespite the advances in vision, speech, and language processing, many problems in artificial intelligence involve more than one modality, such as an intelligent personal assistant (IPA) that should understand human communicative intentions embedded not only in spoken language, but also in body and pictorial languages BIBREF33. Therefore, it is of broad interests to study the modeling and learning approaches across multiple modalities BIBREF34. Benefiting from the advances in image processing and language understanding BIBREF35, a set of tasks that combine both image and text have drawn much attention, which include visual grounding tasks like referring expression understanding and phrase localization BIBREF36, BIBREF37, BIBREF38, image captioning BIBREF39, BIBREF40, BIBREF41, visual QA (VQA) BIBREF42, BIBREF43, BIBREF44, text-to-image generation BIBREF45, BIBREF46, BIBREF47, and visual-language navigation BIBREF48 etc. In these tasks, natural language plays a key role in helping the machine to “understand” the content of the images, where “understand” means to capture the underlying correlations between the semantics embedded in language with the visual features obtained from the images. In addition to text, vision can be combined with speech as well. Such tasks include audio-visual speech recognition BIBREF49, BIBREF50, BIBREF51, speaker recognition BIBREF52, BIBREF53, BIBREF54, as well as speech diarisation BIBREF55, BIBREF56, separation BIBREF57, BIBREF58 and enhancement BIBREF59, which mostly focused on the use of visual features to improve the robustness of the audio-only methods.\nIn this paper, a technical review of the models and learning methods for multimodal intelligence is provided. The main focus is the combination of CV and NLP, which has become an important area for both research communities covering many different tasks and technologies. To provide a more structured perspective, we organize the methods selected in this technical review according to three key topics: representation, fusion, and applications.\nLearning representations for the input data is a core problem for deep learning. For multimodal tasks, collecting paralleled data across all modalities can be quite difficult and leveraging pre-trained representations with desired properties, such as suitable for zero-shot or few-shot learning, is often an effective solution to the issue. Both supervised and unsupervised training based multimodal representation learning methods are reviewed.\nThe fusion of the features or representations of the single modalities is undoubtedly a centric problem of any multimodal task. Different from previous studies that often categorise the related work into early, middle and late stage methods based on the stage that fusion happens in the procedure, we classify them according to the actual operation used in the fusion, such as attention and bilinear pooling, since it becomes difficult to classify some recent complex approaches into stages.\nThree types of applications are reviewed in this paper, namely image captioning, text-to-image synthesis and VQA. This is to give an idea how representation learning and fusion can be applied to specific tasks, and to provide a viewpoint of the situation of the current development of the multimodal applications, especially those integrating vision with natural languages. Visual reasoning methods for VQA are also discussed in the end.\nThis paper is organised as follows. Section SECREF2 reviews the recent progress on developing representations for single or multiple modalities. Section SECREF3 introduces the commonly used fusion methods, particularly attention and bilinear pooling. Applications including caption generation, text-to-image synthesis, VQA, and visual reasoning are introduced in Section SECREF4, followed by conclusions.\nThe main focus is the combination of CV and NLP, which has become an important area for both research communities covering many different tasks and technologies.",

        "question": "Provide a bulleted overview of the components of GDP by expenditure",
        "evidence": "Components of Gross Domestic Product by Expenditure\n\nHere is a description of each GDP component:\n\nC (consumption) is normally the largest GDP component in the economy, consisting of private expenditures in the economy (household final consumption expenditure). These personal expenditures fall under one of the following categories: durable goods, nondurable goods, and services. Examples include food, rent, jewelry, gasoline, and medical expenses, but not the purchase of new housing.\nI (investment) includes, for instance, business investment in equipment, but does not include exchanges of existing assets. Examples include construction of a new mine, purchase of software, or purchase of machinery and equipment for a factory. Spending by households (not government) on new houses is also included in investment. In contrast to its colloquial meaning, \"investment\" in GDP does not mean purchases of financial products. Buying financial products is classed as 'saving', as opposed to investment. This avoids double-counting: if one buys shares in a company, and the company uses the money received to buy plant, equipment, etc., the amount will be counted toward GDP when the company spends the money on those things; to also count it when one gives it to the company would be to count two times an amount that only corresponds to one group of products. Buying bonds or companies' equity shares is a swapping of deeds, a transfer of claims on future production, not directly an expenditure on products; buying an existing building will involve a positive investment by the buyer and a negative investment by the seller, netting to zero overall investment.\nG (government spending) is the sum of government expenditures on final goods and services. It includes salaries of public servants, purchases of weapons for the military and any investment expenditure by a government. It does not include any transfer payments, such as social security or unemployment benefits. Analyses outside the USA will often treat government investment as part of investment rather than government spending.\nX (exports) represents gross exports. GDP captures the amount a country produces, including goods and services produced for other nations' consumption, therefore exports are added.\nM (imports) represents gross imports. Imports are subtracted since imported goods will be included in the terms G, I, or C, and must be deducted to avoid counting foreign supply as domestic.\nNote that C, I, and G are expenditures on final goods and services; expenditures on intermediate goods and services do not count. (Intermediate goods and services are those used by businesses to produce other goods and services within the accounting year.) So for example if a car manufacturer buys auto parts, assembles the car and sells it, only the final car sold is counted towards the GDP. Meanwhile, if a person buys replacement auto parts to install them on their car, those are counted towards the GDP.\n\nAccording to the U.S. Bureau of Economic Analysis, which is responsible for calculating the national accounts in the United States, \"In general, the source data for the expenditures components are considered more reliable than those for the income components [see income method, above].\"\n\nEncyclopedia Britannica records an alternate way of measuring exports minus imports: notating it as the single variable NX.[23",

By examining the so-called scaling exponents, we are able to connect geographical size effects to systematic variations in word use frequencies. We show that the sensitivity of words to population size is also reflected in their meaning. We also investigate how social media language and city size affects the parameters of Zipf's law BIBREF39 , and how the exponent of Zipf's law is different from that of the literature value BIBREF39 , BIBREF40 . We also show that the number of new words needed in longer texts, the Heaps law BIBREF1 exhibits a power-law form on Twitter, indicating a decelerating growth of distinct tokens with city size.\nIn our paper, we aim to capture the effect of city size on language use via individual urban scaling laws of words.",

        "question": "What did ancient cultures around the Mediterranean know about electricity?",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

        "evidence": "Here we compare and contrast our system to the baseline system. A diagram of our system is shown in Figure FIGREF4 .\nThe idea behind this modification is to provide the encoder with access to all morpho-syntactic cues present in the sentence. In contrast to the baseline, which only encodes the immediately adjacent context of a target word, we encode the entire context. All context word forms, lemmas, and MSD tags (in Track 1) are embedded in their respective high-dimensional spaces as before, and their embeddings are concatenated. However, we now reduce the entire past context to a fixed-size vector by encoding it with a forward LSTM, and we similarly represent the future context by encoding it with a backwards LSTM.\nWe introduce an auxiliary objective that is meant to increase the morpho-syntactic awareness of the encoder and to regularise the learning process—the task is to predict the MSD tag of the target form. MSD tag predictions are conditioned on the context encoding, as described in UID15 . Tags are generated with an LSTM one component at a time, e.g. the tag PRO;NOM;SG;1 is predicted as a sequence of four components, INLINEFORM0 PRO, NOM, SG, 1 INLINEFORM1 .\nFor every training instance, we backpropagate the sum of the main loss and the auxiliary loss without any weighting.\nAs MSD tags are only available in Track 1, this augmentation only applies to this track.\nThe parameters of the entire MSD (auxiliary-task) decoder are shared across languages.\nSince a grouping of the languages based on language family would have left several languages in single-member groups (e.g. Russian is the sole representative of the Slavic family), we experiment with random groupings of two to three languages. Multilingual training is performed by randomly alternating between languages for every new minibatch. We do not pass any information to the auxiliary decoder as to the source language of the signal it is receiving, as we assume abstract morpho-syntactic features are shared across languages.\nAfter 20 epochs of multilingual training, we perform 5 epochs of monolingual finetuning for each language. For this phase, we reduce the learning rate to a tenth of the original learning rate, i.e. 0.0001, to ensure that the models are indeed being finetuned rather than retrained.\nWe keep all hyperparameters the same as in the baseline. Training data is split 90:10 for training and validation. We train our models for 50 epochs, adding early stopping with a tolerance of five epochs of no improvement in the validation loss. We do not subsample from the training data.\nWe train models for 50 different random combinations of two to three languages in Track 1, and 50 monolingual models for each language in Track 2. Instead of picking the single model that performs best on the development set and thus risking to select a model that highly overfits that data, we use an ensemble of the five best models, and make the final prediction for a given target form with a majority vote over the five predictions.\nRussian is the sole representative of the Slavic family.",

With these characteristics, the document clusters are 15 times larger than typical DUC clusters of ten documents and five times larger than the 25-document-clusters (Table TABREF26 ). In addition, the documents are also more variable in terms of length, as the (length-adjusted) standard deviation is twice as high as in the other corpora. With these properties, the corpus represents an interesting challenge towards real-world application scenarios, in which users typically have to deal with much more than ten documents.\nBecause we used a large web crawl as the source for our corpus, it contains documents from a variety of genres.

The latter, in particular, is usually considered a significant metric in terms of classification, since it combines in one single value all the four indicators that are generally implied for evaluating the classifier performance (i.e., number of True Positives, False Positives, True Negatives and False Negatives). In our scenario, the meaning of the indicators, for each class, are as follows:\nTrue Positives are the articles classified as belonging to a certain class, that indeed belong to that class (according to the quality ratings given by the WikiProject Medicine);\nTrue Negatives are the articles classified as not belonging to a certain class, that indeed do not belong to that class;\nFalse Positives are the articles classified as belonging to a certain class, that do not belong to that class;\nFalse Negatives are the articles classified as not belonging to a certain class, that instead belong to that class.\nAt a first glance, we observe that, across all the models, the articles with the lowest classification values, for both ROC and F-Measure, are those labeled C and GA. Adding the Domain Informativeness feature produces a classification, which is slightly worse for C and FA articles, but better for the other four classes. This is particularly evident for the F-Measure of the articles of the GA class.

The ROC Area increases for the articles of all the classes within the Full Medical Domain, while the F-Measure is always better than the Baseline and almost always better than the Medical Domain.\nThe size of an article, expressed either as the word count, analyzed in BIBREF20 , or as the article length, as done here, appears a very strong feature, able to discriminate the articles belonging to the highest and lowest quality classes. This is testified also by the results achieved exploiting the baseline model of BIBREF7 , which poorly succeeds in discriminating the articles of the intermediate quality classes, while achieving good results for Stub and FA. Here, the newly introduced features have a predominant effect on the articles of the highest classes. This could be justified by the fact that those articles contain, on average, more text and, then, NLP-based features can exploit more words belonging to a specific domain.\nThen, we observe that the ROC Area and the F-Measure are not tightly coupled (namely: high values for the first metric can correspond to low values for the second one, see for example C and GA): this is due to the nature of the ROC Area, that is affected by the different sizes of the considered classes. As an example, we can observe that the baseline model has the same ROC Area value for the articles of both class B and class GA, while the F-Measure of articles of class B is 0.282 higher than that of class GA.\nFinally, the results confirm that the adoption of domain-based features and, in general, of features that leverage NLP, help to distinguish between articles in the lowest classes and articles in the highest classes, as highlighted in bold in Table 5 . We notice also that exploiting the full medical domain leads us to the achievement of the best results.\nEven if preliminary, we believe that the results are promising and call both for features' further refinement and novel features, able to discriminate among the intermediate classes too.\nThe ROC Area increases for the articles of all the classes within the Full Medical Domain, while the F-Measure is always better than the Baseline and almost always better than the Medical Domain.",

        "question": "What models are used in the framework of GANs?",
        "answer": "A generator and a discriminator.",
        "evidence": "Fortunately, we believe that the introduction of unsupervised generative language models presents a way in which to tackle this particular shortcoming of peer-to-peer markets. In 2014, Ian Goodfellow et. al proposed the general adversarial network (GAN) [5]. The group showcased how this generative model could learn to artificially replicate data patterns to an unprecedented realistic degree [5]. Since then, these models have shown tremendous potential in their ability to generate photo-realistic images and coherent text samples [5].\nThe framework that GANs use for generating new data points employs an end-to-end neural network comprised of two models: a generator and a discriminator [5]. The generator is tasked with replicating the data that is fed into the model, without ever being directly exposed to the real samples. Instead, this model learns to reproduce the general patterns of the input via its interaction with the discriminator.\nThe role of the discriminator, in turn, is to tell apart which data points are ‘real’ and which have been created by the generator. On each run through the model, the generator then adapts its constructed output so as to more effectively ‘trick’ the discriminator into not being able to distinguish the real from the generated data. The end-to-end nature of the model then forces both the generator and discriminator to learn in parallel [7]. While GAN models have shown great potential in their ability to generate realistic data samples, they are notoriously difficult to train. This difficulty arises from two-parts: 1) First, it is difficult to tune the hyper-parameters correctly for the adversarial model to continue learning throughout all of the training epochs [5]. Since both the discriminator and generator are updated via the same gradient, it is very common for the model to fall into a local minima before completing all of the defined training cycles. 2) GANs are computationally expensive to train, given that both models are updated on each cycle in parallel [5]. This compounds the difficulty of tuning the model’s parameters.\nNonetheless, GANs have continued to show their value particularly in the domain of text-generation. Of particular interest for our purposes, Radford et al. propose synthesizing images from text descriptions [3]. The group demonstrates how GANs can produce images that correspond to a user-defined text description. It thus seems feasible that by using a similar model, we can produce text samples that are conditioned upon a set of user-specified keywords.\nWe were similarly influenced by the work of Radford et. al, who argue for the importance of layer normalization and data-specific trained word embeddings for text generation [9] and sentiment analysis categorization. These findings lead us to question whether it is possible to employ recurrent neural networks with long short-term memory gates, as defined by Mikolov et al., to categorize product descriptions into categories based on the product's popularity [6].\nThe framework that GANs use for generating new data points employs an end-to-end neural network comprised of two models: a generator and a discriminator [5].

        "question": "How many collections of scientific articles from the arXiv did the authors study?",
        "answer": "Four.",
        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML).",

        "evidence": "Task-oriented dialog systems have become ubiquitous, providing a means for billions of people to interact with computers using natural language. Moreover, the recent influx of platforms and tools such as Google's DialogFlow or Amazon's Lex for building and deploying such systems makes them even more accessible to various industries and demographics across the globe.\nTools for developing such systems start by guiding developers to collect training data for intent classification: the task of identifying which of a fixed set of actions the user wishes to take based on their query. Relatively few public datasets exist for evaluating performance on this task, and those that do exist typically cover only a very small number of intents (e.g. BIBREF0, which has 7 intents). Furthermore, such resources do not facilitate analysis of out-of-scope queries: queries that users may reasonably make, but fall outside of the scope of the system-supported intents.\nFigure FIGREF1 shows example query-response exchanges between a user and a task-driven dialog system for personal finance. In the first user-system exchange, the system correctly identifies the user's intent as an in-scope balance query. In the second and third exchanges, the user queries with out-of-scope inputs. In the second exchange, the system incorrectly identifies the query as in-scope and yields an unrelated response. In the third exchange, the system correctly classifies the user's query as out-of-scope, and yields a fallback response.\nOut-of-scope queries are inevitable for a task-oriented dialog system, as most users will not be fully cognizant of the system's capabilities, which are limited by the fixed number of intent classes. Correctly identifying out-of-scope cases is thus crucial in deployed systems—both to avoid performing the wrong action and also to identify potential future directions for development. However, this problem has seen little attention in analyses and evaluations of intent classification systems.\nThis paper fills this gap by analyzing intent classification performance with a focus on out-of-scope handling. To do so, we constructed a new dataset with 23,700 queries that are short and unstructured, in the same style made by real users of task-oriented systems. The queries cover 150 intents, plus out-of-scope queries that do not fall within any of the 150 in-scope intents.\nWe evaluate a range of benchmark classifiers and out-of-scope handling methods on our dataset. BERT BIBREF1 yields the best in-scope accuracy, scoring 96% or above even when we limit the training data or introduce class imbalance. However, all methods struggle with identifying out-of-scope queries. Even when a large number of out-of-scope examples are provided for training, there is a major performance gap, with the best system scoring 66% out-of-scope recall. Our results show that while current models work on known classes, they have difficulty on out-of-scope queries, particularly when data is not plentiful. This dataset will enable future work to address this key gap in the research and development of dialog systems. All data introduced in this paper can be found at https://github.com/clinc/oos-eval.\nTo do so, we constructed a new dataset with 23,700 queries that are short and unstructured, in the same style made by real users of task-oriented systems.",

        "question": "In the following passage about mechanical-switch keyboards, which keyboards are the loudest, and how can I make them quieter?",
        "evidence": "Every key on a mechanical-switch keyboard contains a complete switch underneath. Each switch is composed of a housing, a spring, and a stem, and sometimes other parts such as a separate tactile leaf or a clickbar. Switches come in three variants: \"linear\" with consistent resistance, \"tactile\" with a non-audible bump, and \"clicky\" with both a bump and an audible click. Depending on the resistance of the spring, the key requires different amounts of pressure to actuate and to bottom out. The shape of the stem as well as the design of the switch housing varies the actuation distance and travel distance of the switch. The sound can be altered by the material of the plate, case, lubrication, the keycap profile, and even modifying the individual switch. These modifications, or \"mods\" include applying lubricant to reduce friction inside the switch itself, inserting \"switch films\" to reduce wobble, swapping out the spring inside to modify the resistance of the switch itself and many more. Mechanical keyboards allow for the removal and replacement of keycaps with a common stem type.",
        "answer": "Mechanical-switch keyboards with \"Clicky\" switches come with both a bump and an audible click. Without adjusting the material of the plates or case, the way for users to reduce the noise would be to replace the keycaps or applying lubricant to reduce friction inside the switch.",

It also required Germany to give up the gains made via the Treaty of Brest-Litovsk and grant independence to the protectorates that had been established. In Western Europe, Germany was required to recognize Belgian sovereignty over Moresnet and cede control of the Eupen-Malmedy area. Within six months of the transfer, Belgium was required to conduct a plebiscite on whether the citizens of the region wanted to remain under Belgian sovereignty or return to German control, communicate the results to the League of Nations and abide by the League's decision.[n. 8] To compensate for the destruction of French coal mines, Germany was to cede the output of the Saar coalmines to France and control of the Saar to the League of Nations for 15 years; a plebiscite would then be held to decide sovereignty.[n. 9] The treaty restored the provinces of Alsace-Lorraine to France by rescinding the treaties of Versailles and Frankfurt of 1871 as they pertained to this issue.[n. 10] France was able to make the claim that the provinces of Alsace-Lorraine were indeed part of France and not part of Germany by disclosing a letter sent from the Prussian King to the Empress Eugénie that Eugénie provided, in which William I wrote that the territories of Alsace-Lorraine were requested by Germany for the sole purpose of national defense and not to expand the German territory. The sovereignty of Schleswig-Holstein was to be resolved by a plebiscite to be held at a future time (see Schleswig Plebiscites).\n\nIn Central Europe Germany was to recognize the independence of Czechoslovakia (which had actually been controlled by Austria) and cede parts of the province of Upper Silesia.[n. 11] Germany had to recognize the independence of Poland and renounce \"all rights and title over the territory\". Portions of Upper Silesia were to be ceded to Poland, with the future of the rest of the province to be decided by plebiscite. The border would be fixed with regard to the vote and to the geographical and economic conditions of each locality.[n. 12] The Province of Posen (now Poznań), which had come under Polish control during the Greater Poland Uprising, was also to be ceded to Poland. Pomerelia (Eastern Pomerania), on historical and ethnic grounds, was transferred to Poland so that the new state could have access to the sea and became known as the Polish Corridor. The sovereignty of part of southern East Prussia was to be decided via plebiscite while the East Prussian Soldau area, which was astride the rail line between Warsaw and Danzig, was transferred to Poland outright without plebiscite.[n. 13] An area of 51,800 square kilometres (20,000 square miles) was granted to Poland at the expense of Germany. Memel was to be ceded to the Allied and Associated powers, for disposal according to their wishes.[n. 14] Germany was to cede the city of Danzig and its hinterland, including the delta of the Vistula River on the Baltic Sea, for the League of Nations to establish the Free City of Danzig.[n. 15]",

        "evidence": "Datasets: We use two recent benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . These two datasets are created to avoid reversible relation problems, thus the prediction task becomes more realistic and hence more challenging BIBREF18 . Table TABREF7 presents the statistics of WN18RR and FB15k-237.\nEvaluation protocol: Following BIBREF3 , for each valid test triple INLINEFORM0 , we replace either INLINEFORM1 or INLINEFORM2 by each of all other entities to create a set of corrupted triples. We use the “Filtered” setting protocol BIBREF3 , i.e., not taking any corrupted triples that appear in the KG into accounts. We rank the valid test triple and corrupted triples in descending order of their scores. We employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions). Lower MR, higher MRR or higher Hits@10 indicate better performance. Final scores on the test set are reported for the model obtaining the highest Hits@10 on the validation set.\nTraining protocol: We use the common Bernoulli strategy BIBREF20 , BIBREF21 when sampling invalid triples. For WN18RR, BIBREF22 found a strong evidence to support the necessity of a WordNet-related semantic setup, in which they averaged pre-trained word embeddings for word surface forms within the WordNet to create synset embeddings, and then used these synset embeddings to initialize entity embeddings for training their TransE association model. We follow this evidence in using the pre-trained 100-dimensional Glove word embeddings BIBREF23 to train a TransE model on WN18RR.\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 . For ConvKB, we use a new process of training up to 100 epochs and monitor the Hits@10 score after every 10 training epochs to choose optimal hyper-parameters with the Adam initial learning rate in INLINEFORM0 and the number of filters INLINEFORM1 in INLINEFORM2 . We obtain the highest Hits@10 scores on the validation set when using N= 400 and the initial learning rate INLINEFORM3 on WN18RR; and N= 100 and the initial learning rate INLINEFORM4 on FB15k-237.\nLike in ConvKB, we use the same pre-trained entity and relation embeddings produced by TransE to initialize entity and relation embeddings in our CapsE for both WN18RR and FB15k-237 ( INLINEFORM0 ). We set the batch size to 128, the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM1 ), and the number of iterations in the routing algorithm INLINEFORM2 in INLINEFORM3 . We run CapsE up to 50 epochs and monitor the Hits@10 score after each 10 training epochs to choose optimal hyper-parameters. The highest Hits@10 scores for our CapsE on the validation set are obtained when using INLINEFORM4 , INLINEFORM5 and the initial learning rate at INLINEFORM6 on WN18RR; and INLINEFORM7 , INLINEFORM8 and the initial learning rate at INLINEFORM9 on FB15k-237.\nDataset: We use the SEARCH17 dataset BIBREF12 of query logs of 106 users collected by a large-scale web search engine. A log entity consists of a user identifier, a query, top-10 ranked documents returned by the search engine and clicked documents along with the user's dwell time. BIBREF12 constructed short-term (session-based) user profiles and used the profiles to personalize the returned results. They then employed the SAT criteria BIBREF26 to identify whether a returned document is relevant from the query logs as either a clicked document with a dwell time of at least 30 seconds or the last clicked document in a search session (i.e., a SAT click). After that, they assigned a INLINEFORM0 label to a returned document if it is a SAT click and also assigned INLINEFORM1 labels to the remaining top-10 documents. The rank position of the INLINEFORM2 labeled documents is used as the ground truth to evaluate the search performance before and after re-ranking.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set BIBREF12 . The training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.\nEvaluation protocol: Our CapsE is used to re-rank the original list of documents returned by a search engine as follows: (i) We train our model and employ the trained model to calculate the score for each INLINEFORM0 triple. (ii) We then sort the scores in the descending order to obtain a new ranked list. To evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1. For each metric, the higher value indicates better ranking performance.\nWe compare CapsE with the following baselines using the same experimental setup: (1) SE: The original rank is returned by the search engine. (2) CI BIBREF27 : This baseline uses a personalized navigation method based on previously clicking returned documents. (3) SP BIBREF9 , BIBREF11 : A search personalization method makes use of the session-based user profiles. (4) Following BIBREF12 , we use TransE as a strong baseline model for the search personalization task. Previous work shows that the well-known embedding model TransE, despite its simplicity, obtains very competitive results for the knowledge graph completion BIBREF28 , BIBREF29 , BIBREF14 , BIBREF30 , BIBREF15 . (5) The CNN-based model ConvKB is the most closely related model to our CapsE.\nEmbedding initialization: We follow BIBREF12 to initialize user profile, query and document embeddings for the baselines TransE and ConvKB, and our CapsE.\nWe train a LDA topic model BIBREF31 with 200 topics only on the relevant documents (i.e., SAT clicks) extracted from the query logs. We then use the trained LDA model to infer the probability distribution over topics for every returned document. We use the topic proportion vector of each document as its document embedding (i.e. INLINEFORM0 ). In particular, the INLINEFORM1 element ( INLINEFORM2 ) of the vector embedding for document INLINEFORM3 is: INLINEFORM4 where INLINEFORM5 is the probability of the topic INLINEFORM6 given the document INLINEFORM7 .\nWe also represent each query by a probability distribution vector over topics. Let INLINEFORM0 be the set of top INLINEFORM1 ranked documents returned for a query INLINEFORM2 (here, INLINEFORM3 ). The INLINEFORM4 element of the vector embedding for query INLINEFORM5 is defined as in BIBREF12 : INLINEFORM6 , where INLINEFORM7 is the exponential decay function of INLINEFORM8 which is the rank of INLINEFORM9 in INLINEFORM10 . And INLINEFORM11 is the decay hyper-parameter ( INLINEFORM12 ). Following BIBREF12 , we use INLINEFORM13 . Note that if we learn query and document embeddings during training, the models will overfit to the data and will not work for new queries and documents. Thus, after the initialization process, we fix (i.e., not updating) query and document embeddings during training for TransE, ConvKB and CapsE.\nIn addition, as mentioned by BIBREF9 , the more recently clicked document expresses more about the user current search interest. Hence, we make use of the user clicked documents in the training set with the temporal weighting scheme proposed by BIBREF11 to initialize user profile embeddings for the three embedding models.\nHyper-parameter tuning: For our CapsE model, we set batch size to 128, and also the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM0 ). The number of iterations in the routing algorithm is set to 1 ( INLINEFORM1 ). For the training model, we use the Adam optimizer with the initial learning rate INLINEFORM2 INLINEFORM3 INLINEFORM4 INLINEFORM5 INLINEFORM6 INLINEFORM7 . We also use ReLU as the activation function INLINEFORM8 . We select the number of filters INLINEFORM9 . We run the model up to 200 epochs and perform a grid search to choose optimal hyper-parameters on the validation set. We monitor the MRR score after each training epoch and obtain the highest MRR score on the validation set when using INLINEFORM10 and the initial learning rate at INLINEFORM11 .\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 and then follow their training protocols to tune hyper-parameters for TransE and ConvKB, respectively. We also monitor the MRR score after each training epoch and attain the highest MRR score on the validation set when using margin = 5, INLINEFORM0 -norm and SGD learning rate at INLINEFORM1 for TransE; and INLINEFORM2 and the Adam initial learning rate at INLINEFORM3 for ConvKB.\nThe training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.",

        "evidence": "In NMT, the Transformer BIBREF0 is a sequence-to-sequence (seq2seq) model which maps an input sequence to an output sequence through hierarchical multi-head attention mechanisms, yielding a dynamic, context-dependent strategy for propagating information within and across sentences. It contrasts with previous seq2seq models, which usually rely either on costly gated recurrent operations BIBREF15, BIBREF16 or static convolutions BIBREF17.\nGiven $n$ query contexts and $m$ sequence items under consideration, attention mechanisms compute, for each query, a weighted representation of the items. The particular attention mechanism used in BIBREF0 is called scaled dot-product attention, and it is computed in the following way:\nwhere $\\mathbf {Q} \\in \\mathbb {R}^{n \\times d}$ contains representations of the queries, $\\mathbf {K}, \\mathbf {V} \\in \\mathbb {R}^{m \\times d}$ are the keys and values of the items attended over, and $d$ is the dimensionality of these representations. The $\\mathbf {\\pi }$ mapping normalizes row-wise using softmax, $\\mathbf {\\pi }(\\mathbf {Z})_{ij} = \\operatornamewithlimits{\\mathsf {softmax}}(\\mathbf {z}_i)_j$, where\nIn words, the keys are used to compute a relevance score between each item and query. Then, normalized attention weights are computed using softmax, and these are used to weight the values of each item at each query context.\nHowever, for complex tasks, different parts of a sequence may be relevant in different ways, motivating multi-head attention in Transformers. This is simply the application of Equation DISPLAY_FORM7 in parallel $H$ times, each with a different, learned linear transformation that allows specialization:\nIn the Transformer, there are three separate multi-head attention mechanisms for distinct purposes:\nEncoder self-attention: builds rich, layered representations of each input word, by attending on the entire input sentence.\nContext attention: selects a representative weighted average of the encodings of the input words, at each time step of the decoder.\nDecoder self-attention: attends over the partial output sentence fragment produced so far.\nTogether, these mechanisms enable the contextualized flow of information between the input sentence and the sequential decoder.\nIn NMT, the Transformer (Vaswani et al., 2017) is a sequence-to-sequence (seq2seq) model which maps an input sequence to an output sequence through hierarchical multi-head attention mechanisms, yielding a dynamic, context-dependent strategy for propagating information within and across sentences.",

        "evidence": "The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).\nOganesson (Og) is a synthetically produced highly radioactive element. Although IUPAC has used the term \"noble gas\" interchangeably with \"group 18\" and thus included oganesson, it may not be significantly chemically noble and is predicted to break the trend and be reactive due to relativistic effects. Because of the extremely short 0.7 ms half-life of its only known isotope, its chemistry has not yet been investigated.\nFor the first six periods of the periodic table, the noble gases are exactly the members of group 18. Noble gases are typically highly unreactive except when under particular extreme conditions. The inertness of noble gases makes them very suitable in applications where reactions are not wanted. For example, argon is used in incandescent lamps to prevent the hot tungsten filament from oxidizing; also, helium is used in breathing gas by deep-sea divers to prevent oxygen, nitrogen and carbon dioxide toxicity.\nThe properties of the noble gases can be well explained by modern theories of atomic structure: Their outer shell of valence electrons is considered to be \"full\", giving them little tendency to participate in chemical reactions, and it has been possible to prepare only a few hundred noble gas compounds. The melting and boiling points for a given noble gas are close together, differing by less than 10 °C (18 °F); that is, they are liquids over only a small temperature range.\nNeon, argon, krypton, and xenon are obtained from air in an air separation unit using the methods of liquefaction of gases and fractional distillation. Helium is sourced from natural gas fields that have high concentrations of helium in the natural gas, using cryogenic gas separation techniques, and radon is usually isolated from the radioactive decay of dissolved radium, thorium, or uranium compounds. Noble gases have several important applications in industries such as lighting, welding, and space exploration. A helium-oxygen breathing gas is often used by deep-sea divers at depths of seawater over 55 m (180 ft). After the risks caused by the flammability of hydrogen became apparent in the Hindenburg disaster, it was replaced with helium in blimps and balloons.",

        "answer": "Unlike pipeline architectures, the model jointly considers choices available in content selection, lexicalization, and sentence aggregation to avoid greedy local decisions and produce more compact texts, i.e., texts that report more facts per word.",
        "evidence": "The Semantic Web BIBREF0 , BIBREF1 and the growing popularity of Linked Data (data that are published using Semantic Web technologies) have renewed interest in concept-to-text natural language generation (nlg), especially text generation from ontologies BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 . An ontology provides a conceptualization of a knowledge domain (e.g., consumer electronics, diseases) by defining the classes and subclasses of the individuals (entities) in the domain, the possible relations between them etc. The current standard to specify Semantic Web ontologies is owl BIBREF11 , BIBREF12 , a formal language based on description logics BIBREF13 , rdf, and rdf schema BIBREF14 . Given an owl ontology for a knowledge domain, one can publish on the Web machine-readable statements about the domain (e.g., available products, known diseases, their features or symptoms), with the statements having formally defined semantics based on the ontology. nlg can then produce texts describing classes or individuals of the ontology (e.g., product descriptions, information about diseases) from the same statements. This way the same information becomes more easily accessible to both computers (which read the machine-readable statements) and end-users (who read the texts), which is one of the main goals of the Semantic Web.\nnlg systems typically employ a pipeline architecture BIBREF15 . Firstly, content selection chooses the logical facts (axioms, in the case of an owl ontology) to be expressed in the text to be generated. The purpose of the next stage, text planning, ranges from simply ordering the facts to be expressed, in effect also ordering the sentences that will express them, to making more complex decisions about the rhetorical structure of the text. Lexicalization then selects the words and syntactic structures to express each fact as a single sentence. Sentence aggregation may then combine shorter sentences into longer ones. Another component generates appropriate referring expressions (pronouns, noun phrases etc.), and surface realization produces the final text, based on internal representations of the previous decisions. Each stage of the pipeline in effect performs a local optimization, constrained by decisions of the previous stages, and largely unaware of the consequences of its own decisions on the subsequent stages.\nThe pipeline architecture has engineering advantages (e.g., it is easier to specify and monitor the input and output of each stage), but produces texts that may be suboptimal, since the decisions of the generation stages are actually co-dependent BIBREF16 , BIBREF17 , BIBREF18 . Content selection, for example, may greedily select the most important facts among those that are relevant to the purpose of the text, but these facts may require too many words to express, which may be undesirable when space is limited or expensive. Selecting other facts, possibly only slightly less important, may allow the lexicalization stage to use much fewer words, or to report more facts in the same space. Decisions made during content selection and lexicalization (facts to express, words and syntactic structures to use) may also lead to more or fewer sentence aggregation opportunities, affecting the length and readability of the texts. Some of these issues can be addressed by over-generating at each stage (e.g., producing several alternative sets of facts at the end of content selection, several alternative lexicalizations etc.) and employing a final ranking component to select the best combination BIBREF19 . This over-generate and rank approach, however, may also fail to find an optimal solution, and generates an exponentially large number of candidate solutions when several components are pipelined.\nIn this article, we present an Integer Linear Programming (ilp) model that, unlike pipeline architectures, jointly considers choices available in content selection, lexicalization, and sentence aggregation to avoid greedy local decisions and produce more compact texts, i.e., texts that report more facts per word. Compact texts are desirable, for example, when generating short product descriptions to be included as advertisements in Web search results BIBREF20 , BIBREF21 . Question answering may also involve generating a natural language summary of facts (e.g., rdf triples) related to a question, without exceeding a maximum text length BIBREF22 ; the more compact the summary, the more facts can be reported in the available space, increasing the chances of reporting the information sought by the user. Compact texts are also desirable when showing texts on devices with small screens BIBREF23 or as subtitles BIBREF24 .\nIf an importance score is available for each fact, our model can take it into account to maximize the total importance (instead of the total number) of the expressed facts per word. The model itself, however, does not produce importance scores; we assume that the scores are produced by a separate process BIBREF25 , BIBREF26 , not included in our content selection. For simplicity, in the experiments of this article we treat all the facts as equally important. An extended version of our ilp model also considers a limited form of referring expression generation, where the best name must be chosen per individual or class among multiple alternatives. The extended model also avoids sentences that report information that is obvious (to humans) from the names of the individuals and classes (e.g., “A red wine is a kind of wine with red color”). Experiments with three owl ontologies from very different knowledge domains (wines, consumer electronics, diseases) confirm that our models lead to more compact texts, compared to pipeline systems with the same components, with no deterioration or with improvements in the perceived quality of the generated texts. Although solving ilp problems is in general np-hard BIBREF27 , off-the-shelf ilp solvers can be used. The available solvers guarantee finding a globally optimum solution, and they are very fast in practice in the ilp problems we consider, when the the number of available facts (per individual or class being described) is small. We also present an approximation of our ilp models, which is more efficient when the number of available facts is larger and longer texts need to be generated.\nOur ilp models (and approximations) have been embedded in Naturalowl BIBREF10 , an nlg system for owl, as alternatives to the system's original pipeline architecture. We base our work on Naturalowl, because it is the only open-source nlg system for owl that implements all the processing stages of a typical nlg system BIBREF15 , it is extensively documented, and has been tested with several ontologies. The processing stages and linguistic resources of Naturalowl are typical of nlg systems BIBREF28 . Hence, we believe that our work is, at least in principle, also applicable to other nlg systems. Our ilp models do not directly consider text planning, but rely on the (external to the ilp model) text planner of Naturalowl. We hope to include more text planning and referring expression generation decisions directly in our ilp model in future work. We also do not consider surface realization, since it is not particularly interesting in Naturalowl; all the decisions have in effect already been made by the time this stage is reached.\nThe remainder of this article is structured as follows. Section \"Background Information about NaturalOWL\" below provides background information about Naturalowl. Section \"Our Integer Linear Programming Models\" defines our ilp models. Section \"Computational Complexity and Approximations\" discusses the computational complexity of our ilp models, along with the more efficient approximation that can be used when then number of available facts is large. Section \"Experiments\" presents our experiments. Section \"Related Work\" discusses previous related work. Section \"Conclusions and Future Work\" concludes and proposes future work.\nIn this article, we present an Integer Linear Programming (ilp) model that, unlike pipeline architectures, jointly considers choices available in content selection, lexicalization, and sentence aggregation to avoid greedy local decisions and produce more compact texts, i.e., texts that report more facts per word.

        "question": "What are the four properties of good news recommendations in this paper?",
        "answer": "Salience, relative authority, novelty and placement.",
        "evidence": "Wikipedia is the largest source of open and collaboratively curated knowledge in the world. Introduced in 2001, it has evolved into a reference work with around 5m pages for the English Wikipedia alone. In addition, entities and event pages are updated quickly via collaborative editing and all edits are encouraged to include source citations, creating a knowledge base which aims at being both timely as well as authoritative. As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page. However, not all information sources are equal. The online presence of major news outlets is an authoritative source due to active editorial control and their articles are also a timely container of facts. In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them). However, such an approach lacks in (a) reproducibility since rankings vary with time with obvious bias to recent news (b) maintainability since document acquisition for each entity has to be periodically performed. To this effect, our news suggestion considers a news article as input, and determines if it is valuable for Wikipedia. Specifically, given an input news article INLINEFORM0 and a state of Wikipedia, the news suggestion problem identifies the entities mentioned in INLINEFORM1 whose entity pages can improve upon suggesting INLINEFORM2 . Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower. Third, a good recommendation should be able to identify novel news by minimizing redundancy coming from multiple news articles. Finally, addition of facts is facilitated if the recommendations are fine-grained, i.e., recommendations are made on the section level rather than the page level (placement).\nApproach and Contributions. We propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity's salience in the news article, its relative authority and the novelty of the article to the entity page. The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years. The existing news references in the entity pages along with their reference date act as our ground-truth to evaluate our approach. In summary, we make the following contributions.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement.",

All the utterances are annotated by five annotators on a crowd-sourcing platform (Amazon Mechanical Turk), and the labeling work is only based on the textual content. Annotator votes for one of the seven emotions, namely Ekman’s six basic emotions BIBREF1, plus the neutral. If none of the emotion gets more than three votes, the utterance will be marked as “non-neutral”.\nFor the datasets, there are properties worth additional mentioning. Although Friends and EmotionPush share the same data format, they are quite different in nature. Friends is a speech-based dataset which is annotated dialogues from the TV sitcom. It means most of the utterances are generated by the a few main characters. The personality of a character often affects the way of speaking, and therefore “who is the speaker\" might provide extra clues for emotion prediction. In contrast, EmotionPush does not have this trait due to the anonymous mechanism. In addition, features such as typo, hyperlink, and emoji that only appear in chat-based data will need some domain-specific techniques to process.\nIncidentally, the objective of the challenge is to predict the emotion for each utterance.

        "evidence": "Neural machine translation (NMT) exploits neural networks to directly learn to transform sentences from a source language to a target language BIBREF0 , BIBREF1 . Universal multilingual NMT discovered that a neural translation system can be trained on datasets containing source and target sentences in multiple languages BIBREF2 , BIBREF3 . Successfully trained models using this approach can be used to translate arbitrarily between any languages included in the training data. In low-resource scenarios, multilingual NMT has proven to be an extremely useful regularization method since each language direction benefits from the information of the others BIBREF4 , BIBREF5 .\nAn important research focus of multilingual NMT is zero-shot translation (ZS), or translation between languages included in multilingual data for which no directly parallel training data exists. Application-wise, ZS offers a faster and more direct path between languages compared to pivot translation, which requires translation to one or many intermediate languages. This can result in large latency and error propagation, common issues in non-end-to-end pipelines.From a representation learning point of view, there is evidence of NMT's ability to capture language-independent features, which have proved useful for cross-lingual transfer learning BIBREF6 , BIBREF7 and provide motivation for ZS translation. However it is still unclear if minimizing the difference in representations between languages is beneficial for zero-shot learning.\nOn the other hand, the current neural architecture and learning mechanisms of multilingual NMT is not geared towards having a common representation. Different languages are likely to convey the same semantic content with sentences of different lengths BIBREF8 , which makes the desiderata difficult to achieve. Moreover, the loss function of the neural translation model does not favour having sentences encoded in the same representation space regardless of the source language. As a result, if the network capacity is large enough, it may partition itself into different sub-spaces for different language pairs BIBREF9 .\nOur work here focuses on the zero-shot translation aspect of universal multilingual NMT. First, we attempt to investigate the relationship of encoder representation and ZS performance. By modifying the Transformer architecture of BIBREF10 to afford a fixed-size representation for the encoder output, we found that we can significantly improve zero-shot performance at the cost of a lower performance on the supervised language pairs. To the best of our knowledge, this is the first empirical evidence showing that the multilingual model can capture both language-independent and language-dependent features, and that the former can be prioritized during training.\nThis observation leads us to the most important contribution in this work, which is to propose several techniques to learn a joint semantic space for different languages in multilingual models without any architectural modification. The key idea is to prefer a source language-independent representation in the decoder using an additional loss function. As a result, the NMT architecture remains untouched and the technique is scalable to the number of languages in the training data. The success of this method is shown by significant gains on zero-shot translation quality in the standard IWSLT 2017 multilingual benchmark BIBREF11 . Finally, we introduce a more challenging scenario that involves more than one bridge language between source and target languages. This challenging setup confirms the consistency of our zero-shot techniques while clarifying the disadvantages of pivot-based translation.\nThis observation leads us to the most important contribution in this work, which is to propose several techniques to learn a joint semantic space for different languages in multilingual models without any architectural modification.",

        "answer": "Classification task.",
        "evidence": "In recent years, the micro-blogging site Twitter has become a major social media platform with hundreds of millions of users. The short (140 character limit), noisy and idiosyncratic nature of tweets make standard information retrieval and data mining methods ill-suited to Twitter. Consequently, there has been an ever growing body of IR and data mining literature focusing on Twitter. However, most of these works employ extensive feature engineering to create task-specific, hand-crafted features. This is time consuming and inefficient as new features need to be engineered for every task.\nIn this paper, we present Tweet2Vec, a method for generating general-purpose vector representation of tweets that can be used for any classification task. Tweet2Vec removes the need for expansive feature engineering and can be used to train any standard off-the-shelf classifier (e.g., logistic regression, svm, etc). Tweet2Vec uses a CNN-LSTM encoder-decoder model that operates at the character level to learn and generate vector representation of tweets. Our method is especially useful for natural language processing tasks on Twitter where it is particularly difficult to engineer features, such as speech-act classification and stance detection (as shown in our previous works on these topics BIBREF0 , BIBREF1 ).\nThere has been several works on generating embeddings for words, most famously Word2Vec by Mikolov et al. BIBREF2 ). There has also been a number of different works that use encoder-decoder models based on long short-term memory (LSTM) BIBREF3 , and gated recurrent neural networks (GRU) BIBREF4 . These methods have been used mostly in the context of machine translation. The encoder maps the sentence from the source language to a vector representation, while the decoder conditions on this encoded vector for translating it to the target language. Perhaps the work most related to ours is the work of Le and Mikolov le2014distributed, where they extended the Word2Vec model to generate representations for sentences (called ParagraphVec). However, these models all function at the word level, making them ill-suited to the extremely noisy and idiosyncratic nature of tweets. Our character-level model, on the other hand, can better deal with the noise and idiosyncrasies in tweets. We plan to make our model and the data used to train it publicly available to be used by other researchers that work with tweets.\nIn this paper, we present Tweet2Vec, a method for generating general-purpose vector representation of tweets that can be used for any classification task.",

Our main mode of encoding the input, the entity-first method, is shown in Figure FIGREF4. The input sequence begins with a [START] token, then the entity under consideration, then a [SEP] token. After each sentence, a [CLS] token is used to anchor the prediction for that sentence. In this model, the transformer can always observe the entity it should be primarily “attending to” from the standpoint of building representations. We also have an entity-last variant where the entity is primarily observed just before the classification token to condition the [CLS] token's self-attention accordingly. These variants are naturally more computationally-intensive than post-conditioned models, as we need to rerun the transformer for each distinct entity we want to make a prediction for.\nAs an additional variation, we can either run the transformer once per document with multiple [CLS] tokens (a document-level model as shown in Figure FIGREF4) or specialize the prediction to a single timestep (a sentence-level model). In a sentence level model, we formulate each pair of entity $e$ and process step $t$ as a separate instance for our classification task. Thus, for a process with $T$ steps and $m$ entities we get $T \\times m$ input sequences for fine tuning our classification task.\nOur approach consists of structuring input to the transformer network to use and guide the self-attention of the transformers, conditioning it on the entity.

        "answer": "English, French, Spanish, Italian, German, Russian, Chinese and Japanese.",
        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nWe extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese.",

The first stage of PC boot loaders (FSBL, first-stage boot loader) located on fixed disks and removable drives must fit into the first 446 bytes of the Master boot record in order to leave room for the default 64-byte partition table with four partition entries and the two-byte boot signature, which the BIOS requires for a proper boot loader — or even less, when additional features like more than four partition entries (up to 16 with 16 bytes each), a disk signature (6 bytes), a disk timestamp (6 bytes), an Advanced Active Partition (18 bytes) or special multi-boot loaders have to be supported as well in some environments. In floppy and superfloppy volume boot records, up to 59 bytes are occupied for the extended BIOS parameter block on FAT12 and FAT16 volumes since DOS 4.0, whereas the FAT32 EBPB introduced with DOS 7.1 requires even 87 bytes, leaving only 423 bytes for the boot loader when assuming a sector size of 512 bytes. Microsoft boot sectors therefore traditionally imposed certain restrictions on the boot process, for example, the boot file had to be located at a fixed position in the root directory of the file system and stored as consecutive sectors,conditions taken care of by the SYS command and slightly relaxed in later versions of DOS.The boot loader was then able to load the first three sectors of the file into memory, which happened to contain another embedded boot loader able to load the remainder of the file into memory.When Microsoft added LBA and FAT32 support, they even switched to a boot loader reaching over two physical sectors and using 386 instructions for size reasons. At the same time other vendors managed to squeeze much more functionality into a single boot sector without relaxing the original constraints on only minimal available memory (32 KiB) and processor support (8088/8086). For example, DR-DOS boot sectors are able to locate the boot file in the FAT12, FAT16 and FAT32 file system, and load it into memory as a whole via CHS or LBA, even if the file is not stored in a fixed location and in consecutive sectors.\n\nBIOS and UEFI not only load the operating system from a non-volatile device, they also initialize system hardware for operating system.\n\nExamples of first-stage bootloaders include BIOS, coreboot, Libreboot and Das U-Boot.",

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nWe justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.",

        "answer": "It is a bag-of-words model trained to compose word embeddings using dictionary definitions.",
        "evidence": "Distributed representations - dense real-valued vectors that encode the semantics of linguistic units - are ubiquitous in today's NLP research. For single-words or word-like entities, there are established ways to acquire such representations from naturally occurring (unlabelled) training data based on comparatively task-agnostic objectives (such as predicting adjacent words). These methods are well understood empirically BIBREF0 and theoretically BIBREF1 . The best word representation spaces reflect consistently-observed aspects of human conceptual organisation BIBREF2 , and can be added as features to improve the performance of numerous language processing systems BIBREF3 .\nBy contrast, there is comparatively little consensus on the best ways to learn distributed representations of phrases or sentences. With the advent of deeper language processing techniques, it is relatively common for models to represent phrases or sentences as continuous-valued vectors. Examples include machine translation BIBREF8 , image captioning BIBREF9 and dialogue systems BIBREF10 . While it has been observed informally that the internal sentence representations of such models can reflect semantic intuitions BIBREF11 , it is not known which architectures or objectives yield the `best' or most useful representations. Resolving this question could ultimately have a significant impact on language processing systems. Indeed, it is phrases and sentences, rather than individual words, that encode the human-like general world knowledge (or `common sense') BIBREF12 that is a critical missing part of most current language understanding systems.\nWe address this issue with a systematic comparison of cutting-edge methods for learning distributed representations of sentences. We constrain our comparison to methods that do not require labelled data gathered for the purpose of training models, since such methods are more cost-effective and applicable across languages and domains. We also propose two new phrase or sentence representation learning objectives - Sequential Denoising Autoencoders (SDAEs) and FastSent, a sentence-level log-linear bag-of-words model. We compare all methods on two types of task - supervised and unsupervised evaluations - reflecting different ways in which representations are ultimately to be used. In the former setting, a classifier or regression model is applied to representations and trained with task-specific labelled data, while in the latter, representation spaces are directly queried using cosine distance.\nWe observe notable differences in approaches depending on the nature of the evaluation metric. In particular, deeper or more complex models (which require greater time and resources to train) generally perform best in the supervised setting, whereas shallow log-linear models work best on unsupervised benchmarks. Specifically, SkipThought Vectors BIBREF13 perform best on the majority of supervised evaluations, but SDAEs are the top performer on paraphrase identification. In contrast, on the (unsupervised) SICK sentence relatedness benchmark, FastSent, a simple, log-linear variant of the SkipThought objective, performs better than all other models. Interestingly, the method that exhibits strongest performance across both supervised and unsupervised benchmarks is a bag-of-words model trained to compose word embeddings using dictionary definitions BIBREF14 . Taken together, these findings constitute valuable guidelines for the application of phrasal or sentential representation-learning to language understanding systems.\nInterestingly, the method that exhibits strongest performance across both supervised and unsupervised benchmarks is a bag-of-words model trained to compose word embeddings using dictionary definitions",

Similar to existing works BIBREF3 , BIBREF10 , BIBREF12 , we use transfer learning to overcome data sparsity and train a NMT model between the source and the target languages. Specifically, the NMT model (parent model) is trained on the assisting language and target language pairs. We choose English as the assisting language in all our experiments. In our resource-scarce scenario, we have no parallel corpus for the child task. Hence, at test time, the source language sentence is translated using the parent model after performing a word-by-word translation into the assisting language.\nSince the source language and the assisting language (English) have different word order, we hypothesize that it leads to inconsistencies in the contextual representations generated by the encoder for the two languages. In this paper, we propose to pre-order English sentences (assisting language sentences) to match the word-order of the source language and train the parent model on this pre-ordered corpus. In our experiments, we look at scenarios where the assisting language has SVO word order and the source language has SOV word order.\nFor instance, consider the English sentence Anurag will meet Thakur. One of the pre-ordering rule swaps the position of the noun phrase followed by a transitive verb with the transitive verb. The original and the resulting re-ordered parse tree will be as shown in the Table TABREF5 . Applying this reordering rule to the above sentence Anurag will meet Thakur will yield the reordered sentence Anurag Thakur will meet. Additionally, the Table TABREF5 shows the parse trees for the above sentence with and without pre-ordering.\nPre-ordering should also be beneficial for other word order divergence scenarios (e.g., SOV to SVO), but we leave verification of these additional scenarios for future work.\nWe choose English as the assisting language in all our experiments.",

        "answer": "Yes, it is exactly as you suggest, and this is alluded to in the paragraph before theorem 3.3 and made more explicit in section 4.",
        "evidence": "Inverse reinforcement learning (IRL) algorithms infer a task's reward function from the behaviour of task experts. Formally, this behaviour is represented as an expert's policy or a sample of trajectories.\nTo characterise the corresponding invariances, we begin with Q-functions -instrumental to deriving many policies. Q-functions are invariant to S 1 -redistribution since they are defined as an expectation over the successor state S 1 , We show that this is the only invariance for Q-functions. Theorem 3.1. Given an MDP and a policy π, the Q-function for π, Q π , determines R up to S 1redistribution. The optimal Q-function, Q ‹ , has precisely the same invariances.\nThis invariance is inherited by any object that can be derived from a Q-function. However, note that S 1 -redistribution vanishes in simpler spaces of reward functions, as we explore in appendix C.\nWe now turn to policies derived using various planning algorithms. These policies are instrumental in constructing the trajectories studied in IRL. For example, and assume that expert behaviour is drawn from a Boltzmann-rational policy, and Ziebart et al. () assume a Maximum Entropy policy We catalogue the invariances of arbitrary Boltzmann policies, of which these other policies are special cases. As these policies can be derived from Q-functions, they inherit invariance to S 1 -redistribution. We show they are also invariant to potential shaping, but not to any other transformations. Theorem 3.2. Given an MDP, an inverse temperature parameter β, and a base policy π 0 , the Boltzmann policy π π0 β determines R up to S 1 -redistribution and potential shaping. The Boltzmannrational policy, π ‹ β , and the Maximum Entropy policy, π β , have precisely the same invariances. By contrast, and assume that experts follow an optimal policy. Optimal policies inherit S 1 -redistribution invariance from the optimal Q-function, and are also known to be invariant to potential shaping. Under an additional assumption that a given policy is maximally supportive, in that it takes all optimal actions with positive probability, we show that these invariances and any additional invariances are captured in a class of optimalitypreserving transformations (Definition 2.5) based on the set of optimal actions in each state. Theorem 3.3. Given an MDP, let Opsq \" arg max a A ‹ ps, aq. A maximally supportive optimal policy determines R up to optimality-preserving transformations with O.\nAdditional invariances arise if we consider optimal policies that may lack support for optimal actions. As a well-known example, the zero-reward is consistent with any policy in this sense.\nIn the infinite-data limit, a data source of trajectories sampled from a policy reveals the distribution of trajectories induced by the policy, and therefore the policy itself for all states reachable via its supported actions. A Boltzmann policy supports all actions, so in the infinite data limit, samples of trajectories determine the policy for all reachable states. We show this introduces invariance precisely to changes in the reward of unreachable transitions. Theorem 3.4. Given an MDP, an inverse temperature parameter β, and a base policy π 0 , the distribution of trajectories induced by the Boltzmann policy π π0 β from all initial states determines R up to S 1 -redistribution, potential shaping, and a mask of unreachable transitions. The distributions of trajectories induced by the Boltzmann-rational policy, π ‹ β , and the Maximum Entropy policy, π β , from all initial states, have precisely the same invariances.\nSimilarly, trajectories sampled from an optimal policy reveal the policy in those states that its actions reach. This again introduces additional invariance to transformations of reward in other states. Theorem 3.5. Given an MDP, consider the distribution of trajectories induced by a maximally supportive optimal policy. Let S be the set of states in supported trajectories. Let O be the set of functions O defined on S such that Opsq \" arg max a A ‹ ps, aq for all s P S. The induced distribution of trajectories determines R up to optimality-preserving transformations with O P O.\nNote that a mask of the complement of S is not permitted. However, the fact that O is unconstrained outside S leaves reward effectively unconstrained in those states, except that the reward of transitions out of S may have to \"compensate\" for the value of their successor states, to prevent new actions that lead out of S from becoming optimal.\nSo far we have catalogued the invariances of transformations to the reward function of various reward function derived objects. These invariances characterise the infinite-data ambiguity of several reward learning data sources, and the ambiguity tolerance of policy optimisation. In this section, we discuss the implications for the practical evaluation of reward learning data sources.\nWe begin by defining a mathematical framework for comparisons between data sources and applications in terms of their ambiguity. The characterisation of ambiguity and tolerance as invariances to reward transformations suggests a natural partial order on data sources and applications. Recall that the invariances of an object correspond to a partition of the space of reward functions (section 2). We lift the refinement relation for partitions to data sources and applications as follows. Definition 4.1 (Ambiguity refinement). Consider two reward learning data sources (or applications), X and Y . Let Π X and Π Y be the partitions of the space of reward functions corresponding to their respective invariances (definition 2.1). If Π X is a partition refinement of Π Y , we write X ĺ Y , and we say X is no more ambiguous than Y (or X is tolerable for application Y ). If X ĺ Y but not Y ĺ X, then we write X ă Y and say X is (strictly) less ambiguous than Y .\nGiven two data sources X and Y , X ĺ Y corresponds to X conflating no additional reward functions compared to Y in the infinite-data limit. This is the sense in which we say X is no more ambiguous than Y . Moreover, given a downstream application Z, X ĺ Z is precisely the condition of Z tolerating the infinite-data ambiguity of data source X: X ĺ Z if and only if the reward functions conflated by X in the infinite-data limit all lead to the same outcome in Z.\nOf our fundamental reward functions transformations, there are several clear instances of ambiguity refinement in a given MDP, as summarised in figure. Invariance to k-initial potential shaping (k-Φ) corresponds to less ambiguity than general potential shaping (Φ). Likewise positive linear scaling (PLS) is less ambiguous than zero-preserving monotonic transformations (ZPMT), and a mask of impossible transitions is less ambiguous than S'-redistribution (S 1 -R). All of these transformations other than zero-preserving monotonic transformations are less ambiguous than the optimality-preserving transformations we have encountered.\nMore concretely, we can compare the ambiguity of specific data sources. Some of these comparisons are indicated in figure. For example, the ambiguity tolerance of the set of optimal policies is a class of optimality-preserving transformations. Each of the data sources that are less ambiguous than this tolerance are sufficient for policy optimisation.\nNotably, this excludes noiseless comparisons between trajectory fragments in some MDPs. Specifically, policy optimisation does not, in general, tolerate zero-preserving monotonic transformations (ZPMT), while noiseless comparisons are invariant to this transformation in some MDPs (Theorem 3.10). Policy optimisation also does not tolerate data sources based on possible and initial trajectories, which are invariant to a mask of unreachable transitions. However, these sources are tolerable if the application only requires optimal behaviour in reachable states.\nMoreover, we can compare data sources drawn from one MDP to applications in another MDP, such as under a shift in transition dynamics or initial state distribution. This captures the common sim-to-real setting where learning takes place in a simulated or otherwise restricted environment that differs from the final deployment environment. The simplest transformations to consider are masks of possible or reachable transitions. These are parametrised by transition dynamics. In general, the ambiguity corresponding to a mask of X is less than for a mask of X 1 Ą X . For example, if the new dynamics supports transitions that were previously impossible, then sources with invariance to a mask from the original MDP may not be tolerable for applications in the new MDP.\nA similar results holds for S 1 -redistribution, which involves an expectation over MDP dynamics. As an extreme example, we prove that when the transition dynamics are changed for every state and action, S 1 -redistribution under the original dynamics permits an arbitrary Q-function under the new dynamics. Naturally, data sources derived from Q-functions may also be affected by shifts in dynamics. Note that this strong result relies on the formulation of rewards as depending on the successor-state (cf. appendix C). Theorem 4.1. Consider an MDP pS, A, τ, µ 0 , R, γq, a policy π, and alternative transition dynamics τ 1 with τ ps, aq ‰ τ 1 ps, aq for all s P S, a P A. Given a function Q 1 : SˆA Ñ R, there exists a reward function R 1 , produced from R by S 1 -redistribution under τ , such that Q 1 is the Q-function for π under R 1 and τ 1 . Ambiguity refinement is a partial order, and some data sources are indeed incomparable. In consolation, we observe that such incomparable ambiguity is complementary ambiguity, in that by combining the associated data sources, we reduce overall ambiguity about the latent reward. Theorem 4.2. Given data sources X and Y , let pX, Y q denote the combined data source formed from X and Y . If X and Y are incomparable, then pX, Y q ă X and pX, Y q ă Y . This perspective highlights promising directions for the design of reward learning data sources. In particular, this suggests developing reward learning algorithms for mixtures of data sources with complementary ambiguity. Unfortunately, most popular data sources actually appear to have similar kinds of ambiguity given one MDP. However, ambiguity could be reduced by incorporating data from multiple MDPs, along the lines of and.\nBy contrast, Ng & Russell (2000) and Abbeel & Ng (2004) assume that experts follow an optimal policy. Optimal policies inherit S1-redistribution invariance from the optimal Q-function, and are also known to be invariant to potential shaping (Ng et al., 1999). Under an additional assumption that a given policy is maximally supportive, in that it takes all optimal actions with positive probability, we show that these invariances and any additional invariances are captured in a class of optimality_x0002_preserving transformations (Definition 2.5) based on the set of optimal actions in each state.****So far we have catalogued the invariances of transformations to the reward function of various reward function derived objects.

        "evidence": "Due to the semi-supervised nature of the proposed Multitask DCGAN model, we utilize both labeled and unlabeled data. For the unlabeled data, we use audio from the AMI BIBREF8 and IEMOCAP BIBREF7 datasets. For the labeled data, we use audio from the IEMOCAP dataset, which comes with labels for activation and valence, both measured on a 5-point Likert scale from three distinct annotators. Although IEMOCAP provides per-word activation and valence labels, in practice these labels do not generally change over time in a given audio file, and so for simplicity we label each audio clip with the average valence and activation. Since valence and activation are both measured on a 5-point scale, the labels are encoded in 5-element one-hot vectors. For instance, a valence of 5 is represented with the vector INLINEFORM0 . The one-hot encoding can be thought of as a probability distribution representing the likelihood of the correct label being some particular value. Thus, in cases where the annotators disagree on the valence or activation label, this can be represented by assigning probabilities to multiple positions in the label vector. For instance, a label of 4.5 conceptually means that the “correct” valence is either 4 or 5 with equal probability, so the corresponding vector would be INLINEFORM1 . These “fuzzy labels” have been shown to improve classification performance in a number of applications BIBREF14 , BIBREF15 . It should be noted here that we had generally greater success with this fuzzy label method than training the neural network model on the valence label directly, i.e. classification task vs. regression.\nFor the labeled data, we use audio from the IEMOCAP dataset, which comes with labels for activation and valence, both measured on a 5-point Likert scale from three distinct annotators.",

Document collections are growing at an enormous pace and their complete and deep analysis can only be tackled with the help of assisting technologies. This is where content curation technologies based on text analytics come in rehm2016j. Such domain-specific semantic technologies enable the fast and efficient automated processing of heterogeneous document collections, extracting important information units and metadata such as, among others, named entities, numeric expressions, concepts and topics, time expressions, and text structure. One of the fundamental processing tasks is the identification and categorisation of named entities (Named Entity Recognition, NER). Typically, NER is focused upon the identification of semantic categories such as person, location and organization but, especially in domain-specific applications, other typologies have been developed that correspond to task-, language- or domain-specific needs. With regard to the legal domain, the lack of freely available datasets has been a stumbling block for text analytics research. German newspaper datasets from CoNNL 2003 BIBREF0 or GermEval 2014 BIBREF1 are simply not suitable in terms of domain, text type or semantic categories covered.\nThe work described in this paper was carried out under the umbrella of the project Lynx: Building the Legal Knowledge Graph for Smart Compliance Services in Multilingual Europe, a three-year EU-funded project that started in December 2017 BIBREF2. Its objective is the creation of a legal knowledge graph that contains different types of legal and regulatory data BIBREF3, BIBREF4, BIBREF5. Lynx aims to help European companies, especially SMEs, that want to become active in new European countries and markets. The project offers compliance-related services that are currently tested and validated in three use cases (UC): (i) UC1 aims to analyse contracts, enriching them with domain-specific semantic information (document structure, entities, temporal expressions, claims, summaries, etc.); (ii) UC2 focuses on compliance services related to geothermal energy operations, where Lynx supports the understanding of regulatory regimes, including norms and standards; (iii) UC3 is a compliance solution in the domain of labour law, where legal provisions, case law, and expert literature are interlinked, analysed, and compared to define legal strategies for legal practice. The Lynx services are developed for several European languages including English, Spanish, and – relevant for this paper – German BIBREF6.\nDocuments in the legal domain contain multiple references to named entities, especially domain-specific named entities, i. e., jurisdictions, legal institutions, etc. Legal documents are unique and differ greatly from newspaper texts. On the one hand, the occurrence of general-domain named entities is relatively rare. On the other hand, in concrete applications, crucial domain-specific entities need to be identified in a reliable way, such as designations of legal norms and references to other legal documents (laws, ordinances, regulations, decisions, etc.). However, most NER solutions operate in the general or news domain, which makes them inapplicable to the analysis of legal documents BIBREF7, BIBREF8. Accordingly, there is a great need for an NER-annotated dataset consisting of legal documents, including the corresponding development of a typology of semantic concepts and uniform annotation guidelines. In this paper, we describe the development of a dataset of legal documents, which includes (i) named entities and (ii) temporal expressions.\nThe remainder of this article is structured as follows. First, Section SECREF3 gives a brief overview of related work. Section SECREF4 describes, in detail, the rationale behind the annotation of the dataset including the different semantic classes annotated. Section SECREF5 describes several characteristics of the dataset, followed by a short evaluation (Section SECREF6) and conclusions as well as future work (Section SECREF7).\nIn this paper, we describe the devel - opment of a dataset of legal documents, which includes (i) named entities and (ii) temporal expressions.",

He is an inductee of the World Golf Hall of Fame.\n\nFollowing an outstanding junior, college, and amateur golf career, Woods turned professional in 1996 at the age of 20. By the end of April 1997, he had won three PGA Tour events in addition to his first major, the 1997 Masters, which he won by 12 strokes in a record-breaking performance. He reached number one in the Official World Golf Ranking for the first time in June 1997, less than a year after turning pro. Throughout the first decade of the 21st century, Woods was the dominant force in golf. He was the top-ranked golfer in the world from August 1999 to September 2004 (264 consecutive weeks) and again from June 2005 to October 2010 (281 consecutive weeks). During this time, he won 13 of golf's major championships.\n\nThe next decade of Woods's career was marked by comebacks from personal problems and injuries. He took a self-imposed hiatus from professional golf from December 2009 to early April 2010 in an attempt to resolve marital issues with his wife at the time, Elin. Woods admitted to multiple infidelities, and the couple eventually divorced. He fell to number 58 in the world rankings in November 2011 before ascending again to the number-one ranking between March 2013 and May 2014. However, injuries led him to undergo four back surgeries between 2014 and 2017. Woods competed in only one tournament between August 2015 and January 2018, and he dropped off the list of the world's top 1,000 golfers. On his return to regular competition, Woods made steady progress to the top of the game, winning his first tournament in five years at the Tour Championship in September 2018 and his first major in 11 years at the 2019 Masters.\n\nWoods has held numerous golf records. He has been the number one player in the world for the most consecutive weeks and for the greatest total number of weeks of any golfer in history. He has been awarded PGA Player of the Year a record 11 times and has won the Byron Nelson Award for lowest adjusted scoring average a record eight times. Woods has the record of leading the money list in ten different seasons. He has won 15 professional major golf championships (trailing only Jack Nicklaus, who leads with 18) and 82 PGA Tour events (tied for first all time with Sam Snead). Woods leads all active golfers in career major wins and career PGA Tour wins. Woods is the fifth (after Gene Sarazen, Ben Hogan, Gary Player and Jack Nicklaus) player to achieve the career Grand Slam, and the youngest to do so. He is also the second golfer out of two (after Nicklaus) to achieve a career Grand Slam three times.\n\nWoods has won 18 World Golf Championships. He was also part of the American winning team for the 1999 Ryder Cup. In May 2019, Woods was awarded the Presidential Medal of Freedom by Donald Trump, the fourth golfer to receive the honor.\n\nOn February 23, 2021, Woods was hospitalized in serious but stable condition after a single-car collision and underwent emergency surgery to repair compound fractures sustained in his right leg in addition to a shattered ankle. In an interview with Golf Digest in November 2021, Woods indicated that his full-time career as a professional golfer was over, although he would continue to play \"a few events per year\". He returned to the PGA Tour for the first time since the car crash at the 2022 Masters.",

        "question": "Why is the F-15EX Eagle II an ideal aircraft not an ideal aircraft for conducting modern offensive war fighting?",
        "evidence": "In 2018, the United States Air Force (USAF) and Boeing discussed the F-15X or Advanced F-15, a proposed single-seat variant based on the F-15QA to replace USAF F-15C/Ds. Improvements included the AMBER weapons rack to carry up to 22 air-to-air missiles, infrared search and track, advanced avionics and electronic warfare equipment, AESA radar, and revised structure with a service life of 20,000 hours. Single and two-seat variants were proposed, called F-15CX and F-15EX respectively, with identical capabilities. The USAF opted for the two-seat variant, which can be flown either by a single pilot or by a pilot and WSO for complex missions and, someday, controlling collaborative combat aircraft. One reason for this decision is that only two–seat F-15 models remained in production.\n\nThe USAF bought the F-15EX to maintain fleet size as F-22 production ended, the F-35 was delayed, and its F-15Cs aged. Although it is not expected to survive against modern air defenses by 2028, the F-15EX can perform homeland and airbase defense, enforce no-fly zones against limited air defenses, and deploy standoff munitions. In July 2020, the U.S. Defense Department ordered eight F-15EXs over three years for $1.2 billion. In August 2020, the USAF announced plans to replace F-15Cs in the Florida and Oregon Air National Guards with F-15EXs. The F-15EX made its maiden flight on 2 February 2021. The first F-15EX was delivered to the USAF in March 2021, and was flown to Eglin Air Force Base in Florida for further testing.\n\nOn 7 April 2021, its official name Eagle II was announced. The FY2021 defense appropriations bill funded F-15EX procurement at $1.23 billion for 12 aircraft, bringing total orders to 20 aircraft. By May 2022, the USAF had ordered 144 F-15EXs. It has proposed reducing its orders to 80. The first operational F-15EXs are not to receive conformal fuel tanks. The Air Force's proposed budget for fiscal 2024 includes funds to buy 24 more F-15EXs, which would bring the planned fleet up to 104 aircraft.",

        "question": "Based on the reference text, how did the United States implement separation of powers?",
        "evidence": "Separation of powers is a political doctrine originating in the writings of Charles de Secondat, Baron de Montesquieu in The Spirit of the Laws, in which he argued for a constitutional government with three separate branches, each of which would have defined abilities to check the powers of the others. This philosophy heavily influenced the drafting of the United States Constitution, according to which the Legislative, Executive, and Judicial branches of the United States government are kept distinct in order to prevent abuse of power. The American form of separation of powers is associated with a system of checks and balances.\n\nDuring the Age of Enlightenment, philosophers such as Montesquieu advocated the principle in their writings, whereas others, such as Thomas Hobbes, strongly opposed it. Montesquieu was one of the foremost supporters of separating the legislature, the executive, and the judiciary. His writings considerably influenced the Founding Fathers of the United States, such as Alexander Hamilton, who participated in the Constitutional Convention of 1787 which drafted the Constitution.\n\nSome U.S. states did not observe a strict separation of powers in the 18th century. In New Jersey, the governor also functioned as a member of the state's highest court and as the presiding officer of one house of the New Jersey Legislature. The president of Delaware was a member of the Court of Appeals; the presiding officers of the two houses of the state legislature also served in the executive department as vice presidents. In both Delaware and Pennsylvania, members of the executive council served at the same time as judges. On the other hand, many southern states explicitly required separation of powers. Maryland, Virginia, North Carolina and Georgia all kept the branches of government \"separate and distinct.\"",

        "evidence": "High rates of crime and violence in Latin America are undermining growth, threatening human welfare, and impeding social development, according to World Bank and the United Nations Office on Drugs and Crime (UNODC). According to the Financial Times, \"The region registers close to 40 per cent of the world’s murders despite being home to only 9 per cent of the global population. According to Lapop, one in four Latin Americans was assaulted and robbed\" in 2018. Latin America is caught in a vicious circle, where economic growth is thwarted by high crime rates, and insufficient economic opportunity contributes to high crime. Crime and violence thrives as the rule of law is weak, economic opportunity is scarce, and education is poor. Therefore, effectively addressing crime requires a holistic, multi-sectoral approach that addresses its root social, political, and economic causes.\n\nRecent statistics indicate that crime is becoming the biggest problem in Latin America. Amnesty International has declared Latin America as the most dangerous region in the world for journalists to work.\n\nIn Mexico, armed gangs of rival drug smugglers have been fighting it out with one another, thus creating new hazards in rural areas. Crime is extremely high in all of the major cities in Brazil. Wealthy citizens have had to provide for their own security. In large parts of Rio de Janeiro, armed criminal gangs are said to be in control. Crime statistics were high in El Salvador, Guatemala and Venezuela during 1996. The police have not been able to handle the work load and the military have been called in to assist in these countries. There was a very distinct crime wave happening in Latin America. The city that currently topped the list of the world's most violent cities is San Pedro Sula in Honduras, leading various media sources to label it the \"murder capital of the world.\" Colombia registered a homicide rate of 24.4 per 100,000 in 2016, the lowest since 1974. The 40-year low in murders came the same year that the Colombian government signed a peace agreement with the FARC.\n\nCrime is slowing economic growth and undermining democratic consolidation in Latin America. Today, Latin America has the dubious distinction of being most violent region in the world, with combined crime rates more than triple the world average and are comparable to rates in nations experiencing war. This is taking a tremendous toll on development in the region by both affecting economic growth and public faith in democracy.\n\nThe Inter-American Development Bank estimates that Latin America's per capita Gross Domestic Product would be twenty-five percent higher if the region's crime rates were equal to the world average. Similarly, the World Bank has identified a strong correlation between crime and income inequality. Business associations in the region rank crime as the number one issue negatively affecting trade and investment. Crime-related violence also represents the most important threat to public health, striking more victims than HIV/AIDS or other infectious diseases.",

Most professional chefs will choose Kosher salt over table salt as they prefer the texture and usability.

Classical examples of rule-based chatbots include Eliza and Parry. Eliza could also extract some words from sentences and then create another sentence with these words based on their syntatic functions. It was a rule-based solution with no reasoning. Eliza could not \"understand\" what she was parsing. More sophisticated rule-oriented architectures contain grammars and mappings for converting sentences to appropriate sentences using some sort of knowledge. They can be implemented with propositional logic or first-order logic (FOL). Propositional logic assumes the world contains facts (which refer to events, phenomena, symptoms or activities). Usually, a set of facts (statements) is not sufficient to describe a domain in a complete manner. On the other hand, FOL assumes the world contains Objects (e.g., people, houses, numbers, etc.), Relations (e.g. red, prime, brother of, part of, comes between, etc.), and Functions (e.g. father of, best friend, etc.), not only facts as in propositional logic. Moreover, FOL contains predicates, quantifiers and variables, which range over individuals (which are domain of discourse).\nProlog (from French: Programmation en Logique) was one of the first logic programming languages (created in the 1970s), and it is one of the most important languages for expressing phrases, rules and facts. A Prolog program consists of logical formulas and running a program means proving a theorem. Knowledge bases, which include rules in addition to facts, are the basis for most rule-oriented chatbots created so far.\nIn general, a rule is presented as follows: DISPLAYFORM0 \nProlog made it possible to perform the language of Horn clauses (implications with only one conclusion). The concept of Prolog is based on predicate logic, and proving theorems involves a resolute system of denials. Prolog can be distinguished from classic programming languages due to its possibility of interpreting the code in both a procedural and declarative way. Although Prolog is a set of specifications in FOL, it adopts the closed-world assumption, i.e. all knowledge of the world is present in the database. If a term is not in the database, Prolog assumes it is false.\nIn case of Prolog, the FOL-based set of specifications (formulas) together with the facts compose the knowledge base to be used by a rule-oriented chatbot. However an Ontology could be used. For instance, OntBot BIBREF27 uses mapping technique to transform ontologies and knowledge into relational database and then use that knowledge to drive its chats. One of the main issues currently facing such a huge amount of ontologies stored in a database is the lack of easy to use interfaces for data retrieval, due to the need to use special query languages or applications.\nIn rule-oriented chatbots, the degree of intelligent behavior depends on the knowledge base size and quality (which represents the information that the chatbot knows), poor ones lead to weak chatbot responses while good ones do the opposite. However, good knowledge bases may require years to be created, depending on the domain.\nData-oriented\nAs opposed to rule-oriented architectures, where rules have to be explicitly defined, data-oriented architectures are based on learning models from samples of dialogues, in order to reproduce the behavior of the interaction that are observed in the data. Such kind of learning can be done by means of machine learning approach, or by simply extracting rules from data instead of manually coding them.\nAmong the different technologies on which these system can be based, we can highlight classical information retrieval algorithms, neural networks BIBREF28 , Hidden Markov Models (HMM) BIBREF29 , and Partially Observable Markov Decision Process (POMDP) BIBREF30 . Examples include Cleverbot and Tay BIBREF31 . Tay was a chatbot developed by Microsoft that after one day live learning from interaction with teenagers on Twitter, started replying impolite utterances. Microsoft has developed others similar chatbots in China (Xiaoice) and in Japan (Rinna). Microsoft has not associated its publications with these chatbots, but they have published a data-oriented approach BIBREF32 that proposes a unified multi-turn multi-task spoken language understanding (SLU) solution capable of handling multiple context sensitive classification (intent determination) and sequence labeling (slot filling) tasks simultaneously. The proposed architecture is based on recurrent convolutional neural networks (RCNN) with shared feature layers and globally normalized sequence modeling components.\nA survey of public available corpora for can be found in BIBREF33 . A corpus can be classified into different categories, according to: the type of data, whether it is spoken dialogues, transcripts of spoken dialogues, or directly written; the type of interaction, if it is human-human or human-machine; and the domain, whether it is restricted or unconstrained. Two well-known corpora are the Switchboard dataset, which consists of transcripts of spoken, unconstrained, dialogues, and the set of tasks for the Dialog State Tracking Challenge (DSTC), which contain more constrained tasks, for instance the restaurant and travel information sets.\nRule and Data-oriented\nThe model of learning in current A.L.I.C.E. BIBREF13 is incremental or/and interactive learning because a person monitors the robot's conversations and creates new AIML content to make the responses more appropriate, accurate, believable, \"human\", or whatever he/she intends. There are algorithms for automatic detection of patterns in the dialogue data and this process provides the person with new input patterns that do not have specific replies yet, permitting a process of almost continuous supervised refinement of the bot.\nAs already mentioned, A.L.I.C.E. consists of roughly 41,000 elements called categories which is the basic unit of knowledge in AIML. Each category consists of an input question, an output answer, and an optional context. The question, or stimulus, is called the pattern. The answer, or response, is called the template. The two types of optional context are called that and topic. The keyword that refers to the robot's previous utterance. The AIML pattern language consists only of words, spaces, and the wildcard symbols \"_\" and \"*\". The words may consist only of letters and numerals. The pattern language is case invariant. Words are separated by a single space, and the wildcard characters function like words, similar to the initial pattern matching strategy of the Eliza system. More generally, AIML tags transform the reply into a mini computer program which can save data, activate other programs, give conditional responses, and recursively call the pattern matcher to insert the responses from other categories. Most AIML tags in fact belong to this template side sublanguage BIBREF13 .\nAIML language allows:\nSymbolic reduction: Reduce complex grammatical forms to simpler ones.\nDivide and conquer: Split an input into two or more subparts, and combine the responses to each.\nSynonyms: Map different ways of saying the same thing to the same reply.\nSpelling or grammar corrections: the bot both corrects the client input and acts as a language tutor.\nDetecting keywords anywhere in the input that act like triggers for a reply.\nConditionals: Certain forms of branching to produce a reply.\nAny combination of (1)-(6).\nWhen the bot chats with multiple clients, the predicates are stored relative to each client ID. For example, the markup INLINEFORM0 set name INLINEFORM1 \"name\" INLINEFORM2 Matthew INLINEFORM3 /set INLINEFORM4 stores the string Matthew under the predicate named \"name\". Subsequent activations of INLINEFORM5 get name=\"name\" INLINEFORM6 return \"Matthew\". In addition, one of the simple tricks that makes ELIZA and A.L.I.C.E. so believable is a pronoun swapping substitution. For instance:\nU: My husband would like to invest with me.\nS: Who else in your family would like to invest with you?\nClassical examples of rule-based chatbots include Eliza and Parry.",

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena, and human evaluation.",

        "evidence": "Automated, or robotic, journalism aims at news generation from structured data sources, either as the final product or as a draft for subsequent post-editing. At present, automated journalism typically focuses on domains such as sports, finance and similar statistics-based reporting, where there is a commercial product potential due to the high volume of news, combined with the expectation of a relatively straightforward task.\nNews generation systems—especially those deployed in practice—tend to be based on intricate template filling, aiming to give the users the full control of the generated facts, while maintaining a reasonable variability of the resulting text. This comes at the price of having to develop the templates and specify their control logic, neither of which are tasks naturally fitting journalists' work. Further, this development needs to be repeated for every domain, as the templates are not easily transferred across domains. Examples of the template-based news generation systems for Finnish are Voitto by the Finnish Public Service Broadcasting Company (YLE) used for sports news generation, as well as Vaalibotti BIBREF0, a hybrid machine learning and template-based system used for election news.\nBIBREF1 suggested a neural template generation, which jointly models latent templates and text generation. Such a system increases interpretability and controllability of the generation, however, recent sequence-to-sequence systems represent the state-of-the-art in data-to-text generation. BIBREF2\nIn this paper, we report on the development of a news generation system for the Finnish ice hockey news domain, based on sequence-to-sequence methods. In order to train such a system, we compile a corpus of news based on over 2000 game reports from the Finnish News Agency STT. While developing this corpus into a form suitable for training of end-to-end systems naturally requires manual effort, we argue that compiling and refining a set of text examples is a more natural way for journalists to interact with the system, in order for them to codify their knowledge and to adapt it for new domains.\nOur aim is to generate reports that give an overview of a game based on information inferrable from the statistics. Such reports can be used either as a basis for further post-editing by a journalist imprinting own insights and background information, or even used directly as a news stream labelled as machine-generated.\nIn the following, we will introduce the news dataset and the process of its creation, introduce an end-to-end model for news generation, and evaluate its output respective to the abovementioned objectives.\nIn this paper, we report on the development of a news generation system for the Finnish ice hockey news domain, based on sequence-to-sequence methods.",

In 1953 Francis Crick, James Watson, Rosalind Franklin, and colleagues, working at Medical Research Council unit, Cavendish laboratory, Cambridge (now the MRC Laboratory of Molecular Biology), made a double helix model of DNA which changed the entire research scenario. They proposed the DNA structure based on previous research done by Rosalind Franklin and Maurice Wilkins. This research then lead to finding DNA material in other microorganisms, plants and animals.\n\nMolecular biology is not simply the study of biological molecules and their interactions; rather, it is also a collection of techniques developed since the field's genesis which have enabled scientists to learn about molecular processes. In this way it has both complemented and improved biochemistry and genetics as methods (of understanding nature) that began before its advent. One notable technique which has revolutionized the field is the polymerase chain reaction (PCR), which was developed in 1983. PCR is a reaction which amplifies small quantities of DNA, and it is used in many applications across scientific disciplines.\n\nThe central dogma of molecular biology describes the process in which DNA is transcribed into RNA, which is then translated into protein.\n\nMolecular biology also plays a critical role in the understanding of structures, functions, and internal controls within individual cells, all of which can be used to efficiently target new drugs, diagnose disease, and better understand cell physiology. Some clinical research and medical therapies arising from molecular biology are covered under gene therapy whereas the use of molecular biology or molecular cell biology in medicine is now referred to as molecular medicine.",

        "evidence": "It is common knowledge in modern NLP that using large amounts of high-quality training data is a key aspect in building successful machine-learning based systems. For this reason, a major challenge when building such systems is obtaining data in the domain of interest. But what defines a domain? Natural language varies greatly across topics, styles, levels of formality, genres and many other linguistic nuances BIBREF0, BIBREF1, BIBREF2. This overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impossible to well-define the exact requirements from such data with respect to all the aforementioned aspects. On top of that, domain labels are usually unavailable – e.g. in large-scale web-crawled data like Common Crawl which was recently used to train state-of-the-art pretrained language models for various tasks BIBREF3.\nDomain data selection is the task of selecting the most appropriate data for a domain from a large corpus given a smaller set of in-domain data BIBREF4, BIBREF5, BIBREF6, BIBREF7. In this work, we propose to use the recent, highly successful self-supervised pre-trained language models, e.g. devlin-etal-2019-bert,liu2019roberta for domain data selection. As pretrained LMs demonstrate state-of-the-art performance across many NLP tasks after being trained on massive amounts of data, we hypothesize that the robust representations they learn can be useful for mapping sentences to domains in an unsupervised, data-driven approach. We show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering. We then propose methods to leverage these emergent domain clusters for domain data selection in two ways:\nVia distance-based retrieval in the sentence embedding space induced by the pretrained language model.\nBy fine-tuning the pretrained language model for binary classification, where positive examples are from the domain of interest.\nOur methods enable to select relevant data for the task while requiring only a small set of monolingual in-domain data. As they are based solely on the representations learned by self-supervised LMs, they do not require additional domain labels which are usually vague and over-simplify the notion of domain in textual data. We evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8. Our data selection methods enable to train NMT models that outperform those trained using the well-established cross-entropy difference method of BIBREF4 across five diverse domains, achieving a recall of more than 95% in all cases with respect to an oracle that selects the “true” in-domain data.\nOur contributions in this work are as follows. First, we show that pre-trained language models are highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner. Second, we propose methods to select in-domain data based on this property using vector-space retrieval and positive-unlabeled fine-tuning of pretrained language models for binary classification. Third, we show the applicability of our proposed data selection methods on a popular benchmark for domain adaptation in machine translation. An additional contribution is a new, improved data split we create for this benchmark, as we point on issues with previous splits used in the literature. The code and data for this work is publicly available. We hope this work will encourage more research on understanding the data landscape in NLP, enabling to “find the right data for the task” in the age of massive models and diverse data sources.\nIn this work, we propose to use the recent, highly successful self-supervised pre-trained language models for domain data selection.",

Reddit is a diverse platform, with a wide variety of interactional and linguistic styles; it would be pointless to compare hate speech forums against forums dedicated to, say, pictures of wrecked bicycles. Chandrasekharan et al. used a matching design, populating the control group with forums that were as similar as possible to the treatment group, but were not banned from Reddit. The goal is to estimate the counterfactual scenario: in this case, what would have happened had the site not taken action against these specific forums? An ideal control would make it possible to distinguish the effect of the treatment — closing the forums — from other idiosyncratic properties of texts that were treated.\nWe also look for categories of documents that might not be useful. We might remove documents that are meta-discourse, like introductions and notes, or documents that are in a language that is not the primary language of the collection, or duplicates when we are working with archived web pages. However, we need to carefully consider the potential consequences of information we remove. Does its removal alter the data, or the interpretation of the data, we are analyzing? Are we losing anything that might be valuable at a later stage?\nIn many cases, this involves defining a “core” set of documents and a “comparison” set. We often have a specific set of documents in mind: an author’s work, a particular journal, a time period. But if we want to say that this “core” set has some distinctive property, we need a“comparison” set.",

        "answer": "Link prediction, triple classification, and predicting missing relation types.",
        "evidence": "We consider three tasks, link prediction, triple classification, and predicting missing relation types BIBREF24 :\nLink Prediction A common task for knowledge graph completion is link prediction, aiming to predict the missing entity when the other two parts of a triplet (h, r, t) are given. In other words, we need to predict t given (h, r) – tail-entity prediction or predict h given (r, t) – head entity prediction. In-line with prior work BIBREF6 , we report results on link prediction in terms of Mean Reciprocal Rank (MRR), Mean Rank (MR) and Hits@10 on the FB15K-237 dataset in the filtered setting on both sub-tasks: (a) head entity prediction and (b) tail entity prediction. Our results are shown in Table 2 . Note that the present state-of-the-art model, ConvKB achieves an MRR of $(0.375, 0.487)$ on the head and tail link prediction tasks. Observe that simply incorporating Dolores significantly improves the head and tail entity prediction performance by $3.10\\%$ and $7.90\\%$ respectively. Similar improvements are also observed on other metrics like Mean Rank (MR: lower is better) and Hits@10 (higher is better).\nTriple Classification The task of triple classification is to predict whether a triple (h, r, t) is correct or not. Triple classification is a binary classification task widely explored by previous work BIBREF2 , BIBREF9 , BIBREF10 . Since evaluation of classification needs negative triples, we choose WN11 and FB13, two benchmark datasets and report the results of our evaluation in Table 3 . We note that the present state of the art is the ConvKB model. When we add Dolores to the ConvKB model with our embeddings, observe that we improve the average performance of the state-of-the-art model ConvKB slightly by $0.20$ points (from $88.20$ to $88.40$ ). We believe the improvement achieved by adding Dolores is smaller in terms of absolute size because the state-of-the-art model already has excellent performance on this task ( $88.20$ ) suggesting a much slower improvement curve.\nMissing Relation Types The goal of the third task is to reason on the paths connecting an entity pair to predict missing relation types. We follow Das et al. ( BIBREF24 ) and use the same dataset released by Neelakantan, Roth, and McCallum ( BIBREF23 ) which is a subset of FreeBase enriched with information from ClueWeb. The dataset consists of a set of triples ( $e_1$ , r, $e_2$ ) and the set of paths connecting the entity pair ( $e_1$ , $e_2$ ) in the knowledge graph. These triples are collected from ClueWeb by considering sentences that contain the entity pair in Freebase. Neelakantan et al. ( BIBREF23 ) infer the relation type by examining the phrase between two entities. We use the same evaluation criterion as used by Das et al. ( BIBREF24 ) and report our results in Table 4 . Note that the current state-of-the-art model from Das et al. ( BIBREF24 ) yields a score of $71.74$ . Adding Dolores to the model improves the score to $74.42$ yielding a $\\textbf {9.5\\%}$ improvement.\nAltogether, viewing the results on various tasks holistically, we conclude that simply incorporating Dolores into existing state-of-the-art models improves their performance and advances the state of the art on each of these tasks and suggests that our embeddings can be effective in yielding performance gains on a variety of predictive tasks.\nWe consider three tasks, link prediction, triple classification, and predicting missing relation types.",

For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles (variants). In population genetics, nearly every living human's phenotype for the ABO gene is some combination of just these six alleles.\n\nMost alleles observed result in little or no change in the function of the gene product it codes for. However, sometimes, different alleles can result in different observable phenotypic traits, such as different pigmentation. A notable example of this is Gregor Mendel's discovery that the white and purple flower colors in pea plants were the result of a single gene with two alleles.\n\nNearly all multicellular organisms have two sets of chromosomes at some point in their biological life cycle; that is, they are diploid. In this case, the chromosomes can be paired. Each chromosome in the pair contains the same genes in the same order, and place, along the length of the chromosome. For a given gene, if the two chromosomes contain the same allele, they, and the organism, are homozygous with respect to that gene.

        "answer": "ELMo's neural network only contains three layers and the explicit embedding vectors are therefore much easier to extract, it is faster to train and adapt to specific tasks.",
        "evidence": "Word embeddings are representations of words in numerical form, as vectors of typically several hundred dimensions. The vectors are used as an input to machine learning models; for complex language processing tasks these are typically deep neural networks. The embedding vectors are obtained from specialized learning tasks, based on neural networks, e.g., word2vec BIBREF0, GloVe BIBREF1, FastText BIBREF2, ELMo BIBREF3, and BERT BIBREF4. For training, the embeddings algorithms use large monolingual corpora that encode important information about word meaning as distances between vectors. In order to enable downstream machine learning on text understanding tasks, the embeddings shall preserve semantic relations between words, and this is true even across languages.\nProbably the best known word embeddings are produced by the word2vec method BIBREF5. The problem with word2vec embeddings is their failure to express polysemous words. During training of an embedding, all senses of a given word (e.g., paper as a material, as a newspaper, as a scientific work, and as an exam) contribute relevant information in proportion to their frequency in the training corpus. This causes the final vector to be placed somewhere in the weighted middle of all words' meanings. Consequently, rare meanings of words are poorly expressed with word2vec and the resulting vectors do not offer good semantic representations. For example, none of the 50 closest vectors of the word paper is related to science.\nThe idea of contextual embeddings is to generate a different vector for each context a word appears in and the context is typically defined sentence-wise. To a large extent, this solves the problems with word polysemy, i.e. the context of a sentence is typically enough to disambiguate different meanings of a word for humans and so it is for the learning algorithms. In this work, we describe high-quality models for contextual embeddings, called ELMo BIBREF3, precomputed for seven morphologically rich, less-resourced languages: Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish. ELMo is one of the most successful approaches to contextual word embeddings. At time of its creation, ELMo has been shown to outperform previous word embeddings BIBREF3 like word2vec and GloVe on many NLP tasks, e.g., question answering, named entity extraction, sentiment analysis, textual entailment, semantic role labeling, and coreference resolution.\nThis report is split into further five sections. In section SECREF2, we describe the contextual embeddings ELMo. In Section SECREF3, we describe the datasets used and in Section SECREF4 we describe preprocessing and training of the embeddings. We describe the methodology for evaluation of created vectors and results in Section SECREF5. We present conclusion in Section SECREF6 where we also outline plans for further work.\nWhile recently much more complex models such as BERT (Devlin et al., 2019) have further improved the results, ELMo is still useful for several reasons: its neural network only contains three layers and the explicit embedding vectors are therefore much easier to extract, it is faster to train and adapt to specific tasks.",

Venture capital firms or funds invest in these early-stage companies in exchange for equity, or an ownership stake. Venture capitalists take on the risk of financing risky start-ups in the hopes that some of the companies they support will become successful. Because startups face high uncertainty, VC investments have high rates of failure.

        "evidence": "",
        "answer": "The difference between lead climbing and top rope climbing has to do with the location of the rope when the climb is started. In lead climbing the rope begins at the bottom attached to the climber as well as the belayer. The climber must then bring the rope from the bottom of the route to the top by clipping into a series of quick draws that are generally placed 10-15 feet apart. If a person were to fall while lead climbing, they would be caught by the last quick draw they clipped into. When top rope climbing, the rope is already at the top of the route. This means the climber must tie into one side of the rope while their belayer must clip into the other side of the rope. As the climber ascends higher up the route the belayer must take out the slack of the rope as opposed to lead climbing where the belayer would be giving slack. When a person falls in top rope climbing they will only fall a short distance as the rope is already clipped in above them at the top of the route, so how far they fall will be determined by how much slack the belayer has not taken in.",

        "evidence": "Language model pre-training has proven to be highly effective in learning universal language representations from large-scale unlabeled data. ELMo BIBREF0, GPT BIBREF1 and BERT BIBREF2 have achieved great success in many NLP tasks, such as sentiment classification BIBREF3, natural language inference BIBREF4, and question answering BIBREF5.\nDespite its empirical success, BERT's computational efficiency is a widely recognized issue because of its large number of parameters. For example, the original BERT-Base model has 12 layers and 110 million parameters. Training from scratch typically takes four days on 4 to 16 Cloud TPUs. Even fine-tuning the pre-trained model with task-specific dataset may take several hours to finish one epoch. Thus, reducing computational costs for such models is crucial for their application in practice, where computational resources are limited.\nMotivated by this, we investigate the redundancy issue of learned parameters in large-scale pre-trained models, and propose a new model compression approach, Patient Knowledge Distillation (Patient-KD), to compress original teacher (e.g., BERT) into a lightweight student model without performance sacrifice. In our approach, the teacher model outputs probability logits and predicts labels for the training samples (extendable to additional unannotated samples), and the student model learns from the teacher network to mimic the teacher's prediction.\nDifferent from previous knowledge distillation methods BIBREF6, BIBREF7, BIBREF8, we adopt a patient learning mechanism: instead of learning parameters from only the last layer of the teacher, we encourage the student model to extract knowledge also from previous layers of the teacher network. We call this `Patient Knowledge Distillation'. This patient learner has the advantage of distilling rich information through the deep structure of the teacher network for multi-layer knowledge distillation.\nWe also propose two different strategies for the distillation process: ($i$) PKD-Last: the student learns from the last $k$ layers of the teacher, under the assumption that the top layers of the original network contain the most informative knowledge to teach the student; and ($ii$) PKD-Skip: the student learns from every $k$ layers of the teacher, suggesting that the lower layers of the teacher network also contain important information and should be passed along for incremental distillation.\nWe evaluate the proposed approach on several NLP tasks, including Sentiment Classification, Paraphrase Similarity Matching, Natural Language Inference, and Machine Reading Comprehension. Experiments on seven datasets across these four tasks demonstrate that the proposed Patient-KD approach achieves superior performance and better generalization than standard knowledge distillation methods BIBREF6, with significant gain in training efficiency and storage reduction while maintaining comparable model accuracy to original large models. To the authors' best knowledge, this is the first known effort for BERT model compression.\nExperiments on seven datasets across these four tasks demonstrate that the proposed Patient-KD approach achieves superior performance and better generalization than standard knowledge distillation methods, with significant gain in training efficiency and storage reduction while maintaining comparable model accuracy to original large models.",

However, many of the general purpose methods either directly explicitly address the average-case problem [BLS11, MBS13] or at least put emphasis on comparing performance in the average case when evaluating proposed methods [GL21]. We have expanded our related work section to provide additional context for our work, and alternative formulations that are beyond the scope of our paper.",
        "evidence": "Theoretical Analysis of the DG Setting and Algorithms The DG problem setting was first analysed in. Since then there have been some attempts to analyse DG algorithms from a generalisation bound perspective. However these studies have theoretical results that are either restricted to specific model classes, such as kernel machines, or make strong assumptions about how the domains seen during training will resemble those seen at test time-e.g., that all domains are convex combinations of a finite pre-determined set of prototypical domains. In contrast, our Rademacher complexity approach can be applied to a broad range of model classes (including neural networks), and makes comparatively milder assumptions about the relationship between domains-i.e., they are i.i.d. samples from another arbitrary distribution over domains.\nThe majority of the existing work investigating the theoretical foundations of DG follow the initial formalisation of the domain generalisation problem put forth by, where the goal is to minimise the expected error over unseen domains. However, several recent works have also explored the idea of bounding the error on a single unseen domain with the most pathological distribution shift. This type of analysis is typically rooted in methods from causal inference, rather than statistical learning theory. As a consequence, they are able to make stronger claims for the problems they address, but the scope of their analysis is necessarily limited to the scenarios where their assumptions about the underlying causal structures are valid. For example, Janzing (2019) provides bounds that assume problems conform to a specific class of structural equation models, and the analysis is performed under the assumption that infinite training data is available within each of the observed training domains. Throughout the work we address the stan-dard DG formalisation given by, where one is concerned with the expected performance of a model on domains sampled from some distribution over domains.\nOthers rely on trying to link between domain adaptation objectives (where target domains are observable for alignment to source domains) and domain generalisation (where target domains are not observable and thus cannot correctly be used in a learning objective). proceed by making assumptions on the structure of the distribution over possible domains (i.e., that it has support determined by the convex hull of a finite set of prototypical domains), which allows them to upper bound the domain alignment metric. provide a bound that depends on an unobservable domain distance quantity, which they then approximate in experiments using kernel density estimates. is another piece of work that theoretically investigates the generalisation of ERM in a DG setting. They deal with online DG, where each time-step corresponds to observing a new domain, and the learner must produce a new model capable of generalising to novel domains. Another point of difference between their work and the standard DG problem setting of is that the domain at each time-step is chosen by an adversary. They analyse this game for a finite number of time-steps, but they assume each domain has an infinite amount of data. They also put some limitations on the adversary: e.g., it must choose a domain that is a convex combination of a finite number of pre-determined domains. In contrast, our theoretical analysis is in the more realistic setting where one has a finite amount of data per domain, and the domains we consider are not limited to convex combinations of a set of prototypical domains. Possibly the most similar work to our theoretical contributions is due to, who also provide learningtheoretic generalisation bounds for DG. However, their analysis only applies to finite hypothesis classes (which does not include, e.g., linear models or neural networks), whereas ours can be applied to any class amenable to analysis with Rademacher complexity.\nThe main existing empirical analysis on DG is, who compared several state of the art DG methods under a common evaluation and hyper-parameter tuning protocol called DomainBed. They ultimately defend Empirical Risk Minimization (ERM) over more sophisticated alternatives on the grounds that no competitor consistently beats it across the benchmark suite. We also broadly defend ERM, and build on the same benchmark, but differently we provide a much deeper analysis into when and why ERM works. More specifically: (i) We provide a new theoretical analysis of ERM's generalisation quality unlike the prior purely empirical evaluation, (ii) We re-use the DomainBed benchmark to directly corroborate this theory under controlled conditions using linear models where model complexity can be tractably and accurately tuned. (iii) We use our complexity-based analysis to explain the previously erratic results of prior DomainBed competitors in terms of model complexity. (iv) We identify, and empirically validate, the preferred model selection criterion for DG, a point which was inconclusive in.\nThe majority of the existing work investigating the theoretical foundations of DG follow the initial formalisation of the domain generalisation problem put forth by Blanchard et al. (2011), where the goal is to minimise the expected error over unseen domains. However, several recent works have also explored the idea of bounding the error on a single unseen domain with the most pathological distribution shift (Janzing, 2019). This type of analysis is typically rooted in methods from causal inference, rather than statistical learning theory. As a consequence, they are able to make stronger claims for the problems they address, but the scope of their analysis is necessarily limited to the scenarios where their assumptions about the underlying causal structures are valid.",

The story begins on Trantor, the capital of the 12,000-year-old Galactic Empire, powerful but slowly decaying. Hari Seldon, a mathematician and psychologist, has developed psychohistory, a new field of science and psychology that treats all possibilities in large societies by mathematics, allowing for the probabilistic prediction of future events.\n\nBy means of psychohistory, Seldon has discovered the decline and eventual fall of the Empire, angering the aristocratic members of the Commission of Public Safety, the de facto rulers of the Empire. The Commission considers Seldon's views and statements treasonous, and he is arrested along with the young mathematician Gaal Dornick, who has arrived on Trantor to join Seldon's group. Seldon is tried by the Commission; he defends his beliefs, explaining his theories and predictions, including his belief that the Empire will collapse in 300 years and while a Second Empire will eventually rise it will only come after a 30,000-year dark age. He informs the Commission that an alternative to this future is attainable and explains to them that creating a compendium of all human knowledge, the Encyclopedia Galactica, may not prevent the inevitable fall of the Empire but would reduce the dark age to one millennium.\n\nThe skeptical Commission, not wanting to make Seldon a martyr, offers him exile to a remote world, Terminus, with others who could help him create the Encyclopedia. He accepts their offer, prepares for the departure of the \"Encyclopedists\" and receives an imperial decree officially acknowledging his actions. Seldon informs Dornick that, despite the Empire's belief it won by exiling Seldon, the outcome was exactly what he had intended and hoped for. Terminus would be the home of the first Foundation while a second would be established \"at Star's End.\" Seldon then reveals that he is dying, and implores Dornick to become a leader in the new Foundation.",

        "answer": "The American Film Institute and the British Film Institute have Citizen Kane listed as the number one movie of all time.  The British Film Institute has had this rating of Citizen Kane for 50 years.  There are multitudes of reasons why this is a deserving title with a few examples below.\n\n1. Citizen Kane was a thinly veiled movie about a powerful person.  Even before the movie was released newspaper magnate William R Hearst became aware that Kane had many similarities to Hearst.  Both controlled media empires, ran for office, and had giant mansions filled with odds and ends.  Where it allegedly became personal was when scenes showing Kane's wife put through an humiliating run in showbiz propped up by Kane's largesse mirrored Hearst a bit too closely to real life.  Hearst reportedly offered to buy all copies of the film and told newspapers to not print anything or even mention its name.\n\n2. It heralded a new age of cinematography in 1941.  Citizen Kane pioneered in the mainstream many types of compositions and angles we now find quite common.  For a low angle shot in an office to show Kane's towering presence film cameras were too heavy and bulky to sit on the floor.  Cinematographer Gregg Toland solved this by having a hole dug deep enough for camera and tripod to achieve the desired effect.  Also the concept of \"deep focus\" or achieving a large depth of field to make characters near and far appear sharp is difficult to achieve.  These scenes were used to great effect to portray Kane as being surrounded and alone with his wealth later in the movie.  They also provided a literal window into a young innocent Kane during a tense scene inside the house, to which Kane was blissfully unaware but the audience experienced both to jarring effect.\n\n3. Orson Welles was famous and an excellent promoter.  Up to this point Welles most famous exploit had been his radio re-enactment of H.G. Wells \"War of the Worlds.\"  Choosing to follow a newsreel style format and not having an intro saying this is a work of fiction many listeners at home were swept up in the drama and thought an alien invasion was happening.  His popularity from this event carried a great deal of interest over to his first film.  For his first film to come together with a compelling story, technical wizardry, and cultural relevancy truly made it the standard for what a \"Best Film...\" should be.\n\nAs a sidenote in 1921 Citizen Kane won 9 Academy awards including Best Picture, Director, Editing, and Cinematography.

The Canadian brigantine Dei Gratia found her in a dishevelled but seaworthy condition under partial sail and with her lifeboat missing. The last entry in her log was dated ten days earlier. She had left New York City for Genoa on November 7 and was still amply provisioned when found. Her cargo of alcohol was intact, and the captain's and crew's personal belongings were undisturbed. None of those who had been on board were ever seen or heard from again.\n\nMary Celeste was built in Spencer's Island, Nova Scotia, and launched under British registration as Amazon in 1861. She was transferred to American ownership and registration in 1868, when she acquired her new name. Thereafter she sailed uneventfully until her 1872 voyage. At the salvage hearings in Gibraltar following her recovery, the court's officers considered various possibilities of foul play, including mutiny by Mary Celeste's crew, piracy by the Dei Gratia crew or others, and conspiracy to carry out insurance or salvage fraud. No convincing evidence supported these theories, but unresolved suspicions led to a relatively low salvage award.\n\nThe inconclusive nature of the hearings fostered continued speculation as to the nature of the mystery, and the story has repeatedly been complicated by false detail and fantasy. Hypotheses that have been advanced include the effects on the crew of alcohol fumes rising from the cargo, submarine earthquakes, waterspouts, attack by a giant squid, and paranormal intervention.\n\nAfter the Gibraltar hearings, Mary Celeste continued in service under new owners. In 1885, her captain deliberately wrecked her off the coast of Haiti as part of an attempted insurance fraud. The story of her 1872 abandonment has been recounted and dramatized many times in documentaries, novels, plays, and films, and the name of the ship has become a byword for unexplained desertion.

        "answer": "We have now provided results on CIFAR-10 and with convolutional SoftHebb, and added a section dedicated to extensibility",
        "evidence": "We have described SoftHebb, a highly biologically plausible neural algorithm that is founded on a Bayesian ML-theoretic framework. The model consists of elements fully compatible with conventional ANNs. It was previously not known which plasticity rule should be used to learn a Bayesian generative model of the input distribution in ANN WTA networks. Moreover, we showed that Hard WTA networks and neurons with other activation functions can be described within the same framework as variations of the probabilistic model. This theory could provide a new foundation for normative Hebbian ANN designs with practical significance. For example, SoftHebb's properties are sought-after by efficient neuromorphic learning chips. It is unsupervised, local, and requires no error or other feedback currents from upper layers, thus solving hardware-inefficiencies and bio-implausibilities of backpropagation such as weight-transport and update-locking. Surprisingly, it surpasses backpropagation even in accuracy, when training time and network size are limited. In a demonstration that goes beyond the common greedy-training approach to such networks, we achieved update-unlocked operation in practice, by updating the first layer before the input's full processing by the next layer. It is intriguing that, through its biological plausibility, emerge properties commonly associated with biological intelligence, such as speed of learning, and robustness to noise and adversarial attacks. Significant robustness emerges without specialized defences. Furthermore, SoftHebb tends to not merely be robust to attacks, but actually deflect them as specialized SOTA defences aim to do.\nHere, we explored SoftHebb's applicability on several datasets. We measured its accuracy on MNIST, Fashion-MNIST, and CIFAR-10 in preliminary results, and we reported a functional convolutional SoftHebb network that improves accuracy on the significantly harder dataset of CIFAR-10. The convolutional implementation could become the foundation for deeper networks and complex problems. Ultimately, this could provide insights into the role of WTA microcircuits in larger networks in cortex with localized receptive fields, similar to area V1 of cortex. All in all, the algorithm has several properties that are individually interesting and novel, and worth future extension. Combined, however, SoftHebb's properties shown in this work may already enable certain small-scale but previously-impossible applications. For example, fast, on-line, unsupervised learning of simple tasks by edge sensing devices, operating in noisy conditions, with a small battery and only local processing, requires those algorithmic properties that we demonstrated here.\nREPRODUCIBILITY STATEMENT Some of our main contributions are theoretical and their proof is fully reproducible by following the rigorous derivations in the main text and in the appendices. Our experimental results are based on standard machine-learning techniques, while we also describe the hyperparameters and experimental protocols. Moreover, we provide Python code with specific instructions to reproduce the main experiments. calculate weight change ∆w\nHere, we explored SoftHebb’s applicability on several datasets. We measured its accuracy on MNIST, Fashion-MNIST, and CIFAR-10 in preliminary results, and we reported a functional convolutional SoftHebb network that improves accuracy on the significantly harder dataset of CIFAR-10. The convolutional implementation could become the foundation for deeper networks and complex problems.****Finally, we performed preliminary tests on two more difficult datasets, namely Fashion-MNIST (Xiao et al., 2017), which contains grey-scale images of clothing products, and CIFAR-10 (Krizhevsky et al., 2009), which contains RGB images of animals and vehicles. We did not tune the Hebbian networks’ hyper-parameters extensively, so accuracies on these tasks are not definitive but do give a good indication. On F-MNIST, the SoftHebb model achieved a top accuracy of 87.46% whereas a hard WTA reached a similar accuracy of 87.49%. A supervised MLP of the same size achieved a test accuracy of 90.55%. SoftHebb’s generative interpolations (Fig. 3B) are reconfirmed on the F-MNIST dataset, as is its robustness to attacks, whereas, with very small adversarial perturbations, the MLP drops to an accuracy lower than the SoftHebb model (dashed lines in Fig. 2). On CIFAR-10’s preliminary results, the hard WTA and SoftHebb achieved an accuracy of 49.78% and 50.27% respectively. In every tested dataset, it became clear that SoftHebb learns faster than either backpropagation or a hard WTA, by observing the loss and the learned features as in Fig. 1 C & D. The fully-connected SoftHebb layer is applicable on MNIST because the data classes are well-clustered directly in the feature-space of pixels. That is, SoftHebb’s probabilistic model’s assumptions (Def. 2.1) are quite valid for this feature space, and increasing the number of neurons for discovering more refined sub-clusters does help. However, for more complex datasets, this approach alone has diminishing returns and multilayer networks will be needed. Towards this, we implemented a first version of a convolutional SoftHebb, with an added supervised classifier. In these early results, conv-SoftHebb achieved 98.63% on MNIST, and 60.30% on CIFAR-10. This confirms that conv-SoftHebb is functional, but we did not systematically optimize its accuracy or explore its other strengths. This feasibility is evidence that SoftHebb’s strengths may soon also apply to larger networks and datasets.****Figure 3: Examples generated by the adversarial pair PGD attacker/SoftHebb model. SoftHebb’s inherent tendency to deflect the attack towards truly different classes is visible. This tendency can be repurposed to generate interpolations between different classes of the data distribution, a generative property previously unknown for such simple networks.",

        "answer": "WordNet4 (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms)5 , and Russian thesaurus RuThes (115 thousand entries).",
        "evidence": "For evaluating topics with automatic quality measures, we used several English text collections and one Russian collection (Table TABREF7 ). We experiment with three thesauri: WordNet (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms), and Russian thesaurus RuThes (115 thousand entries) BIBREF19 .\nAt the preprocessing step, documents were processed by morphological analyzers. Also, we extracted noun groups as described in BIBREF16 . As baselines, we use the unigram LDA topic model and LDA topic model with added 1000 ngrams with maximal NC-value BIBREF20 extracted from the collection under analysis.\nAs it was found before BIBREF14 , BIBREF16 , the addition of ngrams without accounting relations between their components considerably worsens the perplexity because of the vocabulary growth (for perplexity the less is the better) and practically does not change other automatic quality measures (Table 2).\nWe add the Wordnet data in the following steps. At the first step, we include WordNet synonyms (including multiword expressions) into the proposed similarity sets (LDA-Sim+WNsyn). At this step, frequencies of synonyms found in the same document are summed up in process LDA topic learning as described in Algorithm SECREF3 . We can see that the kernel uniqueness becomes very low, topics are very close to each other in content (Table 2: LDA-Sim+WNsyn). At the second step, we add word direct relatives (hyponyms, hypernyms, etc.) to similarity sets. Now the frequencies of semantically related words are added up enhancing the contribution into all topics of the current document.\nThe Table 2 shows that these two steps lead to great degradation of the topic model in most measures in comparison to the initial unigram model: uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times (Table 2: LDA-Sim+WNsynrel). It is evident that at this step the model has a poor quality. When we look at the topics, the cause of the problem seems to be clear. We can see the overgeneralization of the obtained topics. The topics are built around very general words such as \"person\", \"organization\", \"year\", etc. These words were initially frequent in the collection and then received additional frequencies from their frequent synonyms and related words.\nThen we suppose that these general words were used in texts to discuss specific events and objects, therefore, we change the constructions of the similarity sets in the following way: we do not add word hyponyms to its similarity set. Thus, hyponyms, which are usually more specific and concrete, should obtain additional frequencies from upper synsets and increase their contributions into the document topics. But the frequencies and contribution of hypernyms into the topic of the document are not changed. And we see the great improvement of the model quality: the kernel uniqueness considerably improves, perplexity decreases to levels comparable with the unigram model, topic coherence characteristics also improve for most collections (Table 2:LDA-Sim+WNsynrel/hyp).\nWe further use the WordNet-based similarity sets with n-grams having the same components as described in BIBREF16 . All measures significantly improve for all collections (Table 2:LDA-Sim+WNsr/hyp+Ngrams). At the last step, we try to apply the same approach to ngrams that was previously utilized to hyponym-hypernym relations: frequencies of shorter ngrams and words are summed to frequencies of longer ngrams but not vice versa. In this case we try to increase the contribution of more specific longer ngrams into topics. It can be seen (Table 2) that the kernel uniqueness grows significantly, at this step it is 1.3-1.6 times greater than for the baseline models achieving 0.76 on the ACL collection (Table 2:LDA-Sim+WNsr/hyp+Ngrams/l).\nAt the second series of the experiments, we applied EuroVoc information retrieval thesaurus to two European Union collections: Europarl and JRC. In content, the EuroVoc thesaurus is much smaller than WordNet, it contains terms from economic and political domains and does not include general abstract words. The results are shown in Table 3. It can be seen that inclusion of EuroVoc synsets improves the topic coherence and increases kernel uniqueness (in contrast to results with WordNet). Adding ngrams further improves the topic coherence and kernel uniqueness.\nAt last we experimented with the Russian banking collection and utilized RuThes thesaurus. In this case we obtained improvement already on RuThes synsets and again adding ngrams further improved topic coherence and kernel uniqueness (Table 4).\nIt is worth noting that adding ngrams sometimes worsens the TC-NPMI measure, especially on the JRC collection. This is due to the fact that in these evaluation frameworks, the topics' top elements contain a lot of multiword expressions, which rarely occur in Wikipedia, used for the coherence calculation, therefore the utilized automatic coherence measures can have insufficient evidence for correct estimates.\nFor evaluating topics with automatic quality measures, we used several English text collections and one Russian collection (Table 1). We experiment with three thesauri: WordNet4 (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms)5 , and Russian thesaurus RuThes (115 thousand entries) 6 [18].",

        "evidence": "This study proposed the use of a transfer learning strategy based on fine-tuning to classify PD from speech in three different languages: Spanish, German, and Czech. The transfer learning among languages aimed to improve the accuracy when the models are initialized with utterances from a different language than the one used for the test set. Mel-scale spectrograms extracted from the transitions between voiced and unvoiced segments are used to train a CNN for each language. Then, the trained models are used to fine-tune a model to classify utterances in the remaining two languages.\nThe results indicate that the transfer learning among languages improved the accuracy of the models in up to 8% when a base model trained with Spanish utterances is used to fine-tune a model to classify PD German utterances. The results obtained after the transfer learning are also more balanced in terms of specificity-sensitivity and have a lower variance. In addition, the transfer learning among languages scheme was accurate to improve the accuracy in the target language only when the base model was robust enough. This was observed when the model trained with Spanish utterances was used to initialize the models for German and Czech languages.\nFurther experiments will include the development of more robust base models using hyper-parameter optimization strategies like those based on Bayesian optimization. In addition, the base models will be trained considering two of the languages instead of only one of them. The trained models will also be evaluated to classify the speech of PD patients in several stages of the disease based on the MDS-UPDRS-III score, or based on their dysarthria severity BIBREF20. Further experiments will also include transfer learning among diseases, for instance training a base model with utterances to classify PD, and use such a model to initialize another one to classify other neurological diseases such as Hungtinton's disease.\nThe results obtained after the transfer learning are also more balanced in terms of specificity-sensitivity and have a lower variance.

Next, consider working with an architect to help draw up plans that align to your goals and engage a residential engineer to help determine what updates can be made within the existing house structure and what updates may require substantial modifications or may not be made under the structure. At this point, you may be able to determine whether or not it makes sense to rebuild or remodel, however, to get a final sense of the costs and scope of the project, you should request bids from contracts on your plans and ask that they provide estimated costs and timelines as well as recommendations on how to approach the project. Compare these costs and recommendations against the anticipated costs of leveling and rebuilding the house from scratch, which may also require input from the architect and/or contractor to help determine.

        "answer": "A multitask approach in which a learner takes advantage of the multiplicity of interdependent tasks while jointly learning them.",
        "evidence": "In his work, Caruana BIBREF4 proposed a multitask approach in which a learner takes advantage of the multiplicity of interdependent tasks while jointly learning them. The intuition is that if the tasks are correlated, the learner can learn a model jointly for them while taking into account the shared information which is expected to improve its generalization ability. People express their opinions online on various subjects (events, products..), on several languages and in several styles (tweets, paragraph-sized reviews..), and it is exactly this variety that motivates the multitask approaches. Specifically for Twitter for instance, the different settings of classification like binary, ternary and fine-grained are correlated since their difference lies in the sentiment granularity of the classes which increases while moving from binary to fine-grained problems.\nThere are two main decisions to be made in our approach: the learning algorithm, which learns a decision function, and the data representation. With respect to the former, neural networks are particularly suitable as one can design architectures with different properties and arbitrary complexity. Also, as training neural network usually relies on back-propagation of errors, one can have shared parts of the network trained by estimating errors on the joint tasks and others specialized for particular tasks. Concerning the data representation, it strongly depends on the data type available. For the task of sentiment classification of tweets with neural networks, distributed embeddings of words have shown great potential. Embeddings are defined as low-dimensional, dense representations of words that can be obtained in an unsupervised fashion by training on large quantities of text BIBREF10 .\nConcerning the neural network architecture, we focus on Recurrent Neural Networks (RNNs) that are capable of modeling short-range and long-range dependencies like those exhibited in sequence data of arbitrary length like text. While in the traditional information retrieval paradigm such dependencies are captured using INLINEFORM0 -grams and skip-grams, RNNs learn to capture them automatically BIBREF11 . To circumvent the problems with capturing long-range dependencies and preventing gradients from vanishing, the long short-term memory network (LSTM) was proposed BIBREF12 . In this work, we use an extended version of LSTM called bidirectional LSTM (biLSTM). While standard LSTMs access information only from the past (previous words), biLSTMs capture both past and future information effectively BIBREF13 , BIBREF11 . They consist of two LSTM networks, for propagating text forward and backwards with the goal being to capture the dependencies better. Indeed, previous work on multitask learning showed the effectiveness of biLSTMs in a variety of problems: BIBREF14 tackled sequence prediction, while BIBREF6 and BIBREF15 used biLSTMs for Named Entity Recognition and dependency parsing respectively.\nFigure FIGREF2 presents the architecture we use for multitask learning. In the top-left of the figure a biLSTM network (enclosed by the dashed line) is fed with embeddings INLINEFORM0 that correspond to the INLINEFORM1 words of a tokenized tweet. Notice, as discussed above, the biLSTM consists of two LSTMs that are fed with the word sequence forward and backwards. On top of the biLSTM network one (or more) hidden layers INLINEFORM2 transform its output. The output of INLINEFORM3 is led to the softmax layers for the prediction step. There are INLINEFORM4 softmax layers and each is used for one of the INLINEFORM5 tasks of the multitask setting. In tasks such as sentiment classification, additional features like membership of words in sentiment lexicons or counts of elongated/capitalized words can be used to enrich the representation of tweets before the classification step BIBREF3 . The lower part of the network illustrates how such sources of information can be incorporated to the process. A vector “Additional Features” for each tweet is transformed from the hidden layer(s) INLINEFORM6 and then is combined by concatenation with the transformed biLSTM output in the INLINEFORM7 layer.\nIn his work, Caruana (Caruana, 1997) proposed a multitask approach in which a learner takes advantage of the multiplicity of interdependent tasks while jointly learning them.",

        "question": "What are the two simplification datasets specified by the team?",
        "answer": "WikiSmall and WikiLarge.",
        "evidence": "We evaluate the performance of text simplification using neural machine translation on available parallel sentences and additional simplified sentences.\nDataset. We use two simplification datasets (WikiSmall and WikiLarge). WikiSmall consists of ordinary and simplified sentences from the ordinary and simple English Wikipedias, which has been used as benchmark for evaluating text simplification BIBREF17 , BIBREF18 , BIBREF8 . The training set has 89,042 sentence pairs, and the test set has 100 pairs. WikiLarge is also from Wikipedia corpus whose training set contains 296,402 sentence pairs BIBREF19 , BIBREF20 . WikiLarge includes 8 (reference) simplifications for 2,359 sentences split into 2,000 for development and 359 for testing.\nMetrics. Three metrics in text simplification are chosen in this paper. BLEU BIBREF5 is one traditional machine translation metric to assess the degree to which translated simplifications differed from reference simplifications. FKGL measures the readability of the output BIBREF23 . A small FKGL represents simpler output. SARI is a recent text-simplification metric by comparing the output against the source and reference simplifications BIBREF20 .\nWe evaluate the output of all systems using human evaluation. The metric is denoted as Simplicity BIBREF8 . The three non-native fluent English speakers are shown reference sentences and output sentences. They are asked whether the output sentence is much simpler (+2), somewhat simpler (+1), equally (0), somewhat more difficult (-1), and much more difficult (-2) than the reference sentence.\nMethods. We use OpenNMT BIBREF24 as the implementation of the NMT system for all experiments BIBREF5 . We generally follow the default settings and training procedure described by Klein et al.(2017). We replace out-of-vocabulary words with a special UNK symbol. At prediction time, we replace UNK words with the highest probability score from the attention layer. OpenNMT system used on parallel data is the baseline system. To obtain a synthetic parallel training set, we back-translate a random sample of 100K sentences from the collected simplified corpora. OpenNMT used on parallel data and synthetic data is our model. The benchmarks are run on a Intel(R) Core(TM) i7-5930K CPU@3.50GHz, 32GB Mem, trained on 1 GPU GeForce GTX 1080 (Pascal) with CUDA v. 8.0.\nWe choose three statistical text simplification systems. PBMT-R is a phrase-based method with a reranking post-processing step BIBREF18 . Hybrid performs sentence splitting and deletion operations based on discourse representation structures, and then simplifies sentences with PBMT-R BIBREF25 . SBMT-SARI BIBREF19 is syntax-based translation model using PPDB paraphrase database BIBREF26 and modifies tuning function (using SARI). We choose two neural text simplification systems. NMT is a basic attention-based encoder-decoder model which uses OpenNMT framework to train with two LSTM layers, hidden states of size 500 and 500 hidden units, SGD optimizer, and a dropout rate of 0.3 BIBREF8 . Dress is an encoder-decoder model coupled with a deep reinforcement learning framework, and the parameters are chosen according to the original paper BIBREF20 . For the experiments with synthetic parallel data, we back-translate a random sample of 60 000 sentences from the collected simplified sentences into ordinary sentences. Our model is trained on synthetic data and the available parallel data, denoted as NMT+synthetic.\nResults. Table 1 shows the results of all models on WikiLarge dataset. We can see that our method (NMT+synthetic) can obtain higher BLEU, lower FKGL and high SARI compared with other models, except Dress on FKGL and SBMT-SARI on SARI. It verified that including synthetic data during training is very effective, and yields an improvement over our baseline NMF by 2.11 BLEU, 1.7 FKGL and 1.07 SARI. We also substantially outperform Dress, who previously reported SOTA result. The results of our human evaluation using Simplicity are also presented in Table 1. NMT on synthetic data is significantly better than PBMT-R, Dress, and SBMT-SARI on Simplicity. It indicates that our method with simplified data is effective at creating simpler output.\nResults on WikiSmall dataset are shown in Table 2. We see substantial improvements (6.37 BLEU) than NMT from adding simplified training data with synthetic ordinary sentences. Compared with statistical machine translation models (PBMT-R, Hybrid, SBMT-SARI), our method (NMT+synthetic) still have better results, but slightly worse FKGL and SARI. Similar to the results in WikiLarge, the results of our human evaluation using Simplicity outperforms the other models. In conclusion, Our method produces better results comparing with the baselines, which demonstrates the effectiveness of adding simplified training data.\nWe use two simplification datasets (WikiSmall and WikiLarge).",

For human content analysis, measures of topic coherence and kernel uniqueness are both important and complement each other. Topics can be coherent but have a lot of repetitions. On the other hand, generated topics can be very diverse, but incoherent within each topic.\nTopic coherence is an automatic metric of interpretability. It was shown that the coherence measure has a high correlation with the expert estimates of topic interpretability BIBREF9 , BIBREF17 . Mimno BIBREF9 described an experiment comparing expert evaluation of LDA-generated topics and automatic topic coherence measures. It was found that most \"bad\" topics consisted of words without clear relations between each other.\nNewman et al. BIBREF6 asked users to score topics on a 3-point scale, where 3=“useful” (coherent) and 1=“useless” (less coherent). They instructed the users that one indicator of usefulness is the ease by which one could think of a short label to describe a topic. Then several automatic measures, including WordNet-based measures and corpus co-occurrence measures, were compared. It was found that the best automatic measure having the largest correlation with human evaluation is word co-occurrence calculated as point-wise mutual information (PMI) on Wikipedia articles. Later Lau et al. BIBREF17 showed that normalized poinwise mutual information (NPMI) BIBREF18 calculated on Wikipedia articles correlates even more strongly with human scores.\nWe calculate automatic topic coherence using two measure variants. The coherence of a topic is the median PMI (NPMI) of word pairs representing the topic, usually it is calculated for INLINEFORM0 most probable elements (in our study ten elements) in the topic. The coherence of the model is the median of the topic coherence. To make this measure more objective, it should be calculated on an external corpus BIBREF17 . In our case, we use Wikipedia dumps. DISPLAYFORM0 \nHuman-constructed topics usually have unique main words. The measure of kernel uniqueness shows to what extent topics are different from each other and is calculated as the number of unique elements among most probable elements of topics (kernels) in relation to the whole number of elements in kernels. DISPLAYFORM0 \nIf uniqueness of the topic kernels is closer to zero then many topics are similar to each other, contain the same words in their kernels. In this paper the kernel of a topic means the ten most probable words in the topic. We also calculated perplexity as the measure of language models. We use it for additional checking the model quality.\nIn this paper the kernel of a topic means the ten most probable words in the topic.",

        "answer": "A semi-supervised  QA system.",
        "evidence": "Deep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available. However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents.",

        "question": "What was the The Treaty of Tordesillas?",
        "evidence": "In 1383, John I of Castile, husband of Beatrice of Portugal and son-in-law of Ferdinand I of Portugal, claimed the throne of Portugal. A faction of petty noblemen and commoners, led by John of Aviz (later King John I of Portugal) and commanded by General Nuno Álvares Pereira defeated the Castilians in the Battle of Aljubarrota. With this battle, the House of Aviz became the ruling house of Portugal.\n\nThe new ruling dynasty would proceed to push Portugal to the limelight of European politics and culture, creating and sponsoring works of literature, like the Crónicas d'el Rei D. João I by Fernão Lopes, the first riding and hunting manual Livro da ensinança de bem cavalgar toda sela and O Leal Conselheiro both by King Edward of Portugal and the Portuguese translations of Cicero's De Oficiis and Seneca's De Beneficiis by the well traveled Prince Peter of Coimbra, as well as his magnum opus Tratado da Vertuosa Benfeytoria. In an effort of solidification and centralization of royal power the monarchs of this dynasty also ordered the compilation, organization and publication of the first three compilations of laws in Portugal: the Ordenações d'el Rei D. Duarte, which was never enforced; the Ordenações Afonsinas, whose application and enforcement was not uniform across the realm; and the Ordenações Manuelinas, which took advantage of the printing press to reach every corner of the kingdom. The Avis Dynasty also sponsored works of architecture like the Mosteiro da Batalha (literally, the Monastery of the Battle) and led to the creation of the manueline style of architecture in the 16th century.\n\nPortugal also spearheaded European exploration of the world and the Age of Discovery. Prince Henry the Navigator, son of King John I of Portugal, became the main sponsor and patron of this endeavour. During this period, Portugal explored the Atlantic Ocean, discovering the Atlantic archipelagos the Azores, Madeira, and Cape Verde; explored the African coast; colonized selected areas of Africa; discovered an eastern route to India via the Cape of Good Hope; discovered Brazil, explored the Indian Ocean, established trading routes throughout most of southern Asia; and sent the first direct European maritime trade and diplomatic missions to China and Japan.\n\nIn 1415, Portugal acquired the first of its overseas colonies by conquering Ceuta, the first prosperous Islamic trade centre in North Africa. There followed the first discoveries in the Atlantic: Madeira and the Azores, which led to the first colonization movements.\n\nIn 1422, by decree of King John I, Portugal officially abandoned the previous dating system, the Era of Caesar, and adopted the Anno Domini system, therefore becoming the last catholic realm to do so.\n\n\nThroughout the 15th century, Portuguese explorers sailed the coast of Africa, establishing trading posts for several common types of tradable commodities at the time, ranging from gold to slaves, as they looked for a route to India and its spices, which were coveted in Europe.\n\nThe Treaty of Tordesillas, intended to resolve the dispute that had been created following the return of Christopher Columbus, was made by Pope Alexander VI, the mediator between Portugal and Spain. It was signed on 7 June 1494, and divided the newly discovered lands outside Europe between the two countries along a meridian 370 leagues west of the Cape Verde islands (off the west coast of Africa).\n\n\nIn 1498, Vasco da Gama accomplished what Columbus set out to do and became the first European to reach India by sea, bringing economic prosperity to Portugal and its population of 1.7 million residents, and helping to start the Portuguese Renaissance. In 1500, the Portuguese explorer Gaspar Corte-Real reached what is now Canada and founded the town of Portugal Cove-St. Philip's, Newfoundland and Labrador, long before the French and English in the 17th century, and being just one of many Portuguese colonizations of the Americas.\n\nIn 1500, Pedro Álvares Cabral discovered Brazil and claimed it for Portugal. Ten years later, Afonso de Albuquerque conquered Goa in India, Muscat and Ormuz in the Persian Strait, and Malacca, now a state in Malaysia. Thus, the Portuguese empire held dominion over commerce in the Indian Ocean and South Atlantic. Portuguese sailors set out to reach Eastern Asia by sailing eastward from Europe, landing in such places as Taiwan, Japan, the island of Timor, and in the Moluccas.\n\nAlthough for a long period it was believed the Dutch were the first Europeans to arrive in Australia, there is also some evidence that the Portuguese may have discovered Australia in 1521. From 1519 to 1522, Ferdinand Magellan (Fernão de Magalhães) organized a Spanish expedition to the East Indies which resulted in the first circumnavigation of the globe. Magellan never made it back to Europe as he was killed by natives in the Philippines in 1521.\n\nThe Treaty of Zaragoza, signed on 22 April 1529 between Portugal and Spain, specified the anti-meridian to the line of demarcation specified in the Treaty of Tordesillas.\n\nAll these factors made Portugal one of the world's major economic, military, and political powers from the 15th century until the late 16th century.",

        "evidence": "Although the Sun appears to \"rise\" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion caused many cultures to have mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century.\nAstronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon. However, the term sunrise commonly refers to periods of time both before and after this point:\nTwilight, the period in the morning during which the sky is brightening, but the Sun is not yet visible. The beginning of morning twilight is called astronomical dawn.\nThe period after the Sun rises during which striking colors and atmospheric effects are still seen.\nThe timing of sunrise varies throughout the year and is also affected by the viewer's latitude and longitude, altitude, and time zone. These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun, and the Earth and Moon's paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise.\nIn late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.\nVariations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly.\nAccounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.",

Another problem for abstractive text summarization is that the system summary cannot be easily evaluated automatically. ROUGE BIBREF9 is widely used for summarization evaluation. However, as ROUGE is designed for extractive text summarization, it cannot deal with summary paraphrasing in abstractive text summarization. Besides, as ROUGE is based on the reference, it requires high-quality reference summary for a reasonable evaluation, which is also lacking in the existing dataset for Chinese social media text summarization. We argue that for proper evaluation of text generation task, human evaluation cannot be avoided. We propose a simple and practical human evaluation for evaluating text summarization, where the summary is evaluated against the source content instead of the reference. It handles both of the problems of paraphrasing and lack of high-quality reference. The contributions of this work are summarized as follows:\nFor text summarization, a common automatic evaluation method is ROUGE BIBREF9 . The generated summary is evaluated against the reference summary, based on unigram recall (ROUGE-1), bigram recall (ROUGE-2), and recall of longest common subsequence (ROUGE-L). To facilitate comparison with the existing systems, we adopt ROUGE as the automatic evaluation method. The ROUGE is calculated on the character level, following the previous work BIBREF1 . However, for abstractive text summarization, the ROUGE is sub-optimal, and cannot assess the semantic consistency between the summary and the source content, especially when there is only one reference for a piece of text. The reason is that the same content may be expressed in different ways with different focuses. Simple word match cannot recognize the paraphrasing. It is the case for all of the existing large-scale datasets. Besides, as aforementioned, ROUGE is calculated on the character level in Chinese text summarization, making the metrics favor the models on the character level in practice. In Chinese, a word is the smallest semantic element that can be uttered in isolation, not a character. In the extreme case, the generated text could be completely intelligible, but the characters could still match. In theory, calculating ROUGE metrics on the word level could alleviate the problem. However, word segmentation is also a non-trivial task for Chinese. There are many kinds of segmentation rules, which will produce different ROUGE scores. We argue that it is not acceptable to introduce additional systematic bias in automatic evaluations, and automatic evaluation for semantically related tasks can only serve as a reference. To avoid the deficiencies, we propose a simple human evaluation method to assess the semantic consistency. Each summary candidate is evaluated against the text rather than the reference. If the candidate is irrelevant or incorrect to the text, or the candidate is not understandable, the candidate is labeled bad. Otherwise, the candidate is labeled good. Then, we can get an accuracy of the good summaries. The proposed evaluation is very simple and straight-forward. It focuses on the relevance between the summary and the text. The semantic consistency should be the major consideration when putting the text summarization methods into practice, but the current automatic methods cannot judge properly. For detailed guidelines in human evaluation, please refer to Appendix SECREF6 . In the human evaluation, the text-summary pairs are dispatched to two human annotators who are native speakers of Chinese. As in our setting the summary is evaluated against the reference, the number of the pairs needs to be manually evaluated is four times the number of the pairs in the test set, because we need to compare four systems in total. To decrease the workload and get a hint about the annotation quality at the same time, we adopt the following procedure. We first randomly select 100 pairs in the validation set for the two human annotators to evaluate. Each pair is annotated twice, and the inter-annotator agreement is checked. We find that under the protocol, the inter-annotator agreement is quite high. In the evaluation of the test set, a pair is only annotated once to accelerate evaluation. To further maintain consistency, summaries of the same source content will not be distributed to different annotators.\nWe propose a simple and practical human evaluation for evaluating text summarization, where the summary is evaluated against the source content instead of the reference.

She’s in 9th grade, but attends a pretty small school, so everyone was milling about in a small area…playing cards or MahJong, eating baked goods they got from a sale down the hall, and generally, being teenagers. \nI don’t frequent her school often, but Mads seemed pretty happy, and in her element.  It was lovely to witness.\nI, on the other hand, was having a Terrible, Horrible, No Good, Very Bad Day at work, and when I arrived, I was checking my phone for updates and trying to fight a battle for my new team that I was told was Very Much Not Worth Fighting.  Of course, this was unheeded advice, as—if there’s a hill that’s worth dying on—I will go prostrate myself upon the top of it as effectively as possible. \nAnd so I was fighting an Unwinnable War, and my daughter was overseeing a team of boys scarfing down brownies and picking at their healthy lunches and laughing whilst stacking their Chinese tiles…and I was so crestfallen about the outcome of my silent, onscreen, remote work battle that I didn’t even notice the tears welling up in my eyes, or the fact that I was sitting in the middle of a room filled with teenagers. \nI suppose the only good thing about crying in a room full of teenagers at lunch is that you’re very rarely the ONLY one crying…so there’s that.\nSo there I sat, in fine company, shoulders mildly hunched and trying my damnedest not to wipe my now-soggy nose on my sleeve.  And of course maintaining a smile any time Maddie looked over at me, because Lord knows I was there only to make sure no one flipped over a table (but honestly, not there for much else, as these kids were self-sufficient and rather shockingly well-behaved from what I remembered from 9th grade) and the last thing I wanted was to embarrass my daughter at her school lunch hour.\nBut Maddie was standing there next to the little sofa chair I was on, and she said, “Mom, scoot over.” \nAnd I scooted.\nAnd she sat. \nShe didn’t ask me what was wrong; she already had heard my rumblings before she left for school this morning about the particular work woe I was dealing with today.  Rather, she leaned over and gave me a big hug, right there in front of anyone paying attention—which seemed to be everyone—and assuaged me with soothing “it will all be fine”s and “didn’t I expect these kind of things from my work by now anyway?”s. \nAnd then she got up and went back to her perch at the game table, as nonchalantly as if she had just gotten a drink at the water fountain, and I was left thinking that my teenage daughter had just hugged me in public, in the high school lunch room, in front of two dozen other teenagers I had never met, and she didn’t even flinch. \nThree hours later, the issue at work actually ended up coming up roses;  turns out that dying on that Hill was able to save the initiative after all.   I was really, really happy about that.\nBut the best part of the day was the undeniable recognition that Maddie is Fearless, and Kind, and Confident, and willing to step across lines and do the hard things.

        "evidence": "For this report, we are exploring the field of natural language processing, which is the broad study of how computers and machines can understand human to human communication and how texts are analyzed based on contextual information by machines.\nIn particular, we are using natural language processing to classify news articles as real news or “fake news”. Fake news is misinformation masked under the guise of a real news article, and is used to deceptively influence people’s beliefs.\nFor this report, we are classifying news articles as “real” or “fake”, which will be a binary classification problem - classifying the samples as a positive (with fake news) or negative (not fake news) sample. Many studies have used machine learning algorithms and build classifiers based on features like content, the author’s name and job-title, using lots of models like the convolutional neural network (CNN), recurrent neural network (RNN), feed-forward neural network (FFNN), long-short term memory (LSTM) and logistic regression to find the most optimal model and return its results. In [1], the author built a classifier using natural language processing and used models like CNN, RNN, FFNN, and Logistic Regression and concluded that the CNN classifiers could not be as competitive as the RNN classifiers. The authors in [2] think that their study can be improved by having more features like knowing the history of lies spoken by the news reporter or the speaker.\nMoreover, apart from the traditional machine learning methods, new models have also been developed. One of the newer models, TraceMiner, creates an LSTM-RNN model inferring from the embedding of social media users in the social network structure to propagate through the path of messages and has provided high classification accuracy$^{5}$. FAKEDETECTOR is another inference model developed to detect the credibility of the fake news which is considered to be quite reliable and accurate$^{7}$.\nThere also have been studies that have a different approach. A paper surveys the current state-of-the-art technologies that are imperative when adopting and developing fake news detection and provides a classification of several accurate assessment methods that analyze the text and detect anomalies$^{3}$.\nThese previous approaches lack a clear contextual analysis used in NLP. We considered the semantic meaning of each word and we feel that the presence of particular words influence the meaning. We reckoned this important since we felt the contextual meaning of the text needs to be preserved and analyzed for better classification. Other studies emphasize the user and features related to them. In [4], “45 features…[were used] for predicting accuracy...across four types: structural, user, content, and temporal,” so features included characteristics beyond the text. Article [6] \"learn[s] the representations of news articles, creators and subjects simultaneously.\" In our project, we emphasize the content by working with articles whose labels only relate to the text, nothing outside that scope, and have used SVM, Logistic Regression, ANN, LSTM, and Random Forest.\nWe had devised this problem into 3 different phases: pre-processing, text-to-numeric representation conversion using pre-trained algorithms, and then evaluate the models using state-of-the-art machine learning algorithms. We had analysed the data set and in particular the text part of the data explaining how it is distributed and then we converted each text into numeric representation using pre-training models such as TFIDF, CV and W2V for vector representation. Finally, we evaluated our numeric conversion data using significant machine learning algorithms such as neural networks, classification algorithms etc to perform the classification.\nWe had devised this problem into 3 different phases: pre-processing, text-to-numeric representation conversion using pre-trained algorithms, and then evaluate the models using state-of-the-art machine learning algorithms.",

Others will introduce whatever food is being served to the adults — this could be complex foods with spices such as fajitas, curries and hamburgers. Although young babies will rarely have teeth, their gums are very hard and can mash food. For example, a common early food is mini cucumber, which also may alleviate pains with teething.  For how to feed your baby, there are two main categories with many variations in between 1/ Baby-led weaning 2/ Spoon fed. Baby-led does what it sounds like — the baby leads their own feeding. This is often done by the caregiver laying out a few foods (Soft, Mashable, Age-appropriate and safe — void of choking hazards) and letting the baby choose which foods to pick up and eat and how much.

HSD is required to build a multi-class classification model that is capable of classifying an item to one of 3 classes (hate, offensive, clean). Hate speech (hate): an item is identified as hate speech if it (1) targets individuals or groups on the basis of their characteristics; (2) demonstrates a clear intention to incite harm, or to promote hatred; (3) may or may not use offensive or profane words. Offensive but not hate speech (offensive): an item (posts/comments) may contain offensive words but it does not target individuals or groups on the basis of their characteristics. Neither offensive nor hate speech (clean): normal item, it does not contain offensive language or hate speech.\nThe fundamental idea of this system is how to make a system that has the diversity of viewing an input. That because of the variety of the meaning in Vietnamese language especially with the acronym, teen code type. To make this diversity, after cleaning raw text input, we use multiple types of word tokenizers. Each one of these tokenizers, we combine with some types of representation methods, including word to vector methods such as continuous bag of words BIBREF5, pre-trained embedding as fasttext (trained on Wiki Vietnamese language) BIBREF6 and sonvx (trained on Vietnamese newspaper) BIBREF7. Each sentence has a set of words corresponding to a set of word vectors, and that set of word vectors is a representation of a sentence. We also make a sentence embedding by using RoBERTa architecture BIBREF8. CBOW and RoBERTa models trained on text from some resources including VLSP 2016 Sentiment Analysis, VLSP 2018 Sentiment Analysis, VLSP 2019 HSD and text crawled from Facebook. After having sentence representation, we use some classification models to classify input sentences. Those models will be described in detail in the section SECREF13.

First, sentences were decomposed into sentence graphs based on clausal and prepositional boundaries, then assembled into multi-sentence “explanation graphs”. Questions were answered by ranking these candidate explanation graphs, using answer correctness as well as features that capture the connectivity of key-terms in the graphs as a proxy for explanation quality. Jansen at al. jansen2017framing showed that it is possible to learn to generate high quality explanations for 60% of elementary science questions using this method, an increase of 15% over a baseline that retrieved single continuous passages of text as answer justifications. Critically, in their error analysis Jansen et al. found that for questions answered incorrectly by their system, nearly half had successfully generated high-quality explanation graphs and ranked these highly, though they were not ultimately selected. They suggest that the process of building and ranking explanations would be aided by developing more expensive second-pass reranking processes that are able to better recognize the components and structure of high-quality explanations within a short list of candidates.\nKnowledge bases of tables, or “table stores”, have recently been proposed as a semi-structured knowledge formalism for question answering that balances the cost of manually crafting highly-structured knowledge bases with the difficulties in acquiring this knowledge from free text BIBREF14 , BIBREF15 , BIBREF16 . The methods for question answering over tables generally take the form of constructing chains of multiple table rows that lead from terms in the question to terms in the answer, while the tables themselves are generally either collected from the web, automatically generated by extracting relations from free text, or manually constructed.\nAt the collection end of the spectrum, Pasupat and Liang pasupat:2015 extract 2,108 HTML tables from Wikipedia, and propose a method of answering these questions by reasoning over the tables using formal logic. They also introduce the WikiTableQuestions dataset, a set of 22,033 question-answer pairs (such as “Greece held its last Summer Olympics during which year?”) that can be answered using these tables. Demonstrating the ability for collection at scale, Sun et al. sun:2016table extract a total of 104 million tables from Wikipedia and the web, and develop a model that constructs relational chains between table rows using a deep-learning framework. Using their system and table store, Sun et al. demonstrate state-of-the-art performance on several benchmark datasets, including WebQuestions BIBREF17 , a set of popular questions asked from the web designed to be answerable using the large structured knowledge graph Freebase (e.g. “What movies does Morgan Freeman star in?”).\nIn terms of automatic generation, though relations are often represented as $<subject, relation, argument>$ triples, Yin et al. yin:2015answering create a large table containing 120M n-tuple relations using OpenIE BIBREF18 , arguing that the extra expressivity afforded by these more detailed relations allows their system to answer more complex questions. Yin et al. use this to successfully reason over the WebQuestions dataset, as well as their own set of questions with more complex prepositional and adverbial constraints.\nElementary science exams contain a variety of complex and challenging inference problems BIBREF1 , BIBREF2 , with nearly 70% of questions requiring some form of causal, process, or model-based reasoning to solve and produce an explanation for. In spite of these exams being taken by millions of students each year, elementary students tend not to be fast or voluminous readers by adult standards, making this a surprisingly low-resource domain for grade-appropriate study guides and other materials. The questions also tend to require world knowledge expressed in grade-appropriate language (like that bears have fur and that fur keeps animals warm) to solve. Because of these requirements and limitations, table stores for elementary science QA tend to be manually or semi-automatically constructed, and comparatively small.\nKhashabi et al. Khashabi:2016TableILP provide the largest elementary science table store to date, containing approximately 5,000 manually-authored rows across 65 tables based on science curriculum topics obtained from study guides and a small corpus of questions. Khashabi et al. also augment their tablestore with 4 tables containing 2,600 automatically generated table rows using OpenIE triples. Reasoning is accomplished using an integer-linear programming algorithm to chain table rows, with Khashabi et al. reporting that an average of 2 table rows are used to answer each question. Evaluation on a small set of 129 science questions achieved passing performance (61%), with an ablation study showing that the bulk of their model's performance was from the manually authored tables.\nTo help improve the quality of automatically generated tables, Dalvi et al. Dalvi2016IKE introduce an interactive tool for semi-automatic table generation that allows annotators to query patterns over large corpora. They demonstrate that this tool can improve the speed of knowledge generation by up to a factor of 4 over manual methods, while increasing the precision and utility of the tables up to seven fold compared to completely automatic methods.\nAll of the above systems share the commonality that they work to connect (or aggregate) multiple pieces of knowledge that, through a variety of inference methods, move towards the goal of answering questions. Fried et al. fried2015higher report that information aggregation for QA is currently very challenging, with few methods able to combine more than two pieces of knowledge before succumbing to semantic drift, or the phenomenon of two pieces of knowledge being erroneously connected due to shared lexical overlap, incomplete word-sense disambiguation, or other noisy signals (e.g. erroneously aggregating a sentence about Apple computers to an inference when working to determine whether apples are a kind of fruit). In a generating a corpus of natural-language explanations for 432 elementary science questions, Jansen et al. jansen2016:COLING found that the average question requires aggregating 4 separate pieces of knowledge to explainably answer, with some questions requiring much longer explanations.\nThough few QA solvers explicitly report the aggregation limits of their algorithms, Fried et al. fried2015higher, Khabashi et al. Khashabi:2016TableILP and Jansen et al. jansen2017framing appear to show limits or substantial decreases in performance after aggregating two pieces of knowledge. To the best of our knowledge, of systems that use information aggregation, only Jansen et al. jansen2017framing explicitly rate the explanatory performance of the justifications from their model, with good explanations generated for only 60% of correctly answered questions. Taken together, all of this suggests that performance on information aggregation and explainable question answering is still far from human performance, and could substantially benefit from a large corpus of training data for these tasks.\nIn terms of question answering, the ability to provide compelling human-readable explanations for answers to questions has been proposed as a complementary metric to assess QA performance alongside the proportion of questions answered correctly.",

        "evidence": "The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It has one of the longest spans in the United States.\n\nThe toll bridge was conceived as early as the California Gold Rush days, with \"Emperor\" Joshua Norton famously advocating for it, but construction did not begin until 1933. Designed by Charles H. Purcell, and built by American Bridge Company, it opened on Thursday, November 12, 1936, six months before the Golden Gate Bridge. It originally carried automobile traffic on its upper deck, with trucks, cars, buses and commuter trains on the lower, but after the Key System abandoned rail service on April 20, 1958, the lower deck was converted to all-road traffic as well. On October 12, 1963, traffic was reconfigured to one way traffic on each deck, westbound on the upper deck, and eastbound on the lower deck, with trucks and buses allowed on the upper deck.\n\nIn 1986, the bridge was unofficially dedicated to former California Governor James Rolph.\n\nThe bridge has two sections of roughly equal length; the older western section, officially known as the Willie L. Brown Jr. Bridge (after former San Francisco Mayor and California State Assembly Speaker Willie L. Brown Jr.), connects downtown San Francisco to Yerba Buena Island, and the newer unnamed eastern section connects the island to Oakland. The western section is a double suspension bridge with two decks, westbound traffic being carried on the upper deck while eastbound is carried on the lower one. The largest span of the original eastern section was a cantilever bridge.\n\nDuring the 1989 Loma Prieta earthquake, a portion of the eastern section's upper deck collapsed onto the lower deck and the bridge was closed for a month. Reconstruction of the eastern section of the bridge as a causeway connected to a self-anchored suspension bridge began in 2002; the new eastern section opened September 2, 2013, at a reported cost of over $6.5 billion; the original estimate of $250 million was for a seismic retrofit of the existing span. Unlike the western section and the original eastern section of the bridge, the new eastern section is a single deck carrying all eastbound and westbound lanes. Demolition of the old east span was completed on September 8, 2018.",

        "question": "How many fine-grained semantic classes are defined by authors?",
        "answer": "19.",
        "evidence": "We defined 19 fine-grained semantic classes. The (proto)typical classes are person, location and organization. In addition, we defined more specific semantic classes for the legal domain. These are the coarse-grained classes legal norm, case-by-case regulation, court decision and legal literature. The classes legal norm and case-by-case regulation include designations and references, while court decision and legal literature include only references.\nIn the process of developing the typology and annotation guidelines, the fine-grained classes continent KONT (which belongs to location), university UNI, institute IS and museum MUS (which belonged to organization) were eliminated due their low frequency in the corpus (less than 50 occurrences). This is why university, institute and museum were subsumed under the fine-grained class organization. Continent was integrated into landscape.\nThe specification of the 19 fine-grained classes was motivated by the need for distinguishing entities in the legal domain. A first distinction was made between standards and binding acts. Standards, which belong to legal norm, are legal rules adopted by a legislative body in a legislative process. We can distinguish further between law, ordinance (German national standards) and European legal norm. Binding acts (circulars, administrative acts, contracts, administrative regulations, directives, etc.) belong to the category of case-by-case-regulation. It includes regulation (arrangements or instructions on subjects) and contract (agreements between subjects). In addition, court decision and legal literature, which are important in the decision making process, were put into their own categories.\nWithin person, we distinguish between judge and lawyer, key roles mentioned frequently in the decisions. Locations are categorised in terms of their size in country, city and street. Organizations are divided based on their role in the process, into public or social organization, state institution, (private) economic company, mostly as a legal entity, and court as an organ of jurisprudence.\nThe coarse-grained class person PER contains the fine-grained classes judge RR, lawyer AN and person PER (such as accused, plaintiff, defendant, witness, appraiser, expert, etc.), who are involved in a court process and mentioned in a decision. In example (UNKREF19), the same surname occurs twice in a sentence, one as judge and one as person.\nZwar ist Paul Kirchhof RR mit dem Vizepräsidenten Kirchhof PER als dessen Bruder in der Seitenlinie im zweiten Grade verwandt...\n`Although Paul Kirchhof is related to the Vice President Kirchhof as his brother in the second-degree sidelines...'\nThe coarse-grained class location LOC contains names of topographic objects, divided into country LD, city ST, street STR and landscape LDS. Country (UNKREF21) includes countries, states or city-states and city (UNKREF22) includes to cities, villages or communities. Street (UNKREF23) refers to avenues, squares, municipalities, attractions etc., i. e., named entities within a city or a village. Landscape (UNKREF24) includes continents, lakes, rivers and other geographical objects.\n... hat bislang nur das Land Mecklenburg-Vor-ForestGreen!50I pommern LD Gebrauch gemacht.\n`So far, only the state of Mecklenburg-Vorpommern has made use of it.'\nDem Haftbefehl liegt eine Entscheidung des Berufungsgerichts in Bukarest ST vom 18.

Social and public institutions such as parties, associations, centres, communities, unions, educational institutions or research institutions are grouped into the fine-grained class organization ORG (UNKREF26). Institution INN (UNKREF27) contain public administrations, including federal and state ministries and the constitutional bodies of the Federal Republic of Germany at the federal and state level, i. e., the Federal Government, the Federal Council, the Bundestag, the state parliaments and governments. Company UN (UNKREF28) includes commercial legal entities.\nDer FC Bayern München ORG schloss den Beschwerdeführer ... aus dem Verein aus ...\n`Bayern Munich closed the complainant ... from the club ....'\nDie Landesregierung Rheinland-Pfalz INN hat von einer Stellungnahme abgesehen.\n`The state government of Rhineland-Palatinate refrained from commenting.'\n... eingeführte Smartphone-Modellreihe des US-amerikanischen Unternehmens Apple UN ...\n`... introduced smartphone model series of the US company Apple ...'\nCourt designations play a central role in decisions, which is why they are collected in their own class court GRT. These are designations of federal, supreme, provincial and local courts. The designations of the courts at the country level are composed of the names of the ordinary jurisdiction and their location (UNKREF29). Furthermore, brands are often discussed in decisions of the Federal Patent Court. They are subsumed under brand MRK, which can be contextual and semantically ambiguous, such as `Becker' from (UNKREF30), which has evolved from a personal name.\nDiesen Anspruch hat das LSG Mecklenburg-RubineRed!50I Vorpommern GRT mit Urteil vom 22.2.2017 verneint ...\n`This claim was rejected by the LSG Mecklenburg-Vorpommern by judgment of 22.2.2017 ...'\nVorliegend stehen sich die Widerspruchsmarke Becker Mining MRK und die angegriffene Marke Becker MRK gegenüber.\n`In the present case, the opposing brand Becker Mining and the challenged brand Becker face each other.'\nNorms are divided according to their legal status into the fine-grained classes of law GS, ordinance VO and European legal norm EUN. Law is composed of the standards adopted and designated by the legislature (Bundestag, Bundesrat, Landtag). Ordinance includes standards adopted by a federal or provincial government or by a ministry. European legal norm includes norms of European primary or secondary legislation, European organizations and other conventions and agreements.\nExample (UNKREF32) includes a reference to the `Part-Time and Limited Term Employment Act' and the designation 'Basic Law'. The complex reference consists of the reference to the particular section of the law, its name and abbreviation (in brackets), date of issue, the reference in parenthesis and the details of the most recent change. Cases such as this one are a full reference. Example (UNKREF33), on the other hand, shows a short reference consisting of information on the corresponding section of the law and the abbreviated name of the statutory order.\n... § 14 Absatz 2 Satz 2 des Gesetzes über Teil- RedOrange!70I zeitarbeit und IRedOrange!70Ibefristete Arbeitsverträge RedOrange!70I(Tz-RedOrange!70I BfG) vom 21.

These include regulation VS and contract VT. Regulation is an internal order or instruction from a superordinate authority to a subordinate, regulating their activities. In addition to administrative regulations, these include guidelines, circulars and decrees. In contrast to legal norm, these rules have no direct effect on the citizen. The class contract includes public contracts, international treaties and collective agreements. Some designations and references from these classes are similar to legal norm (UNKREF35, UNKREF36).\n... insbesondere durch die Richtlinien zur Be-Peach!70I wertung des Grundvermögens –BewRGr– vom Peach!70I 19.

It does not have any subclasses, the coarsed and fine-grained versions are identical. In court decision, the name of the official decision-making collection, the volume and the numbered article are cited. Often mentioned are also the court, if necessary the decision type, date and file number. Example (UNKREF39) cites decisions of the Federal Constitutional Court (BVerfG) and the Federal Social Court (BSG). Decisions of the BVerfG are referenced with regard to pages, while decisions of the BSG are sorted according to paragraphs, numbers and marginal numbers.\nLegal literature LIT also contains references, but they refer to legal commentaries, legislative material, legal textbooks and monographs. The commentary in example (UNKREF39) includes the details of an author's and/or publisher's name, the name of a legal norm, a paragraph and a paragraph number. Multiple authors are separated by a slash. Textbooks and monographs are cited as usual (author's name, title, edition, year of publication, page number).

        "answer": "The Golden State Warriors won the most recent NBA championship in 2022.  In the last 8 years they reached the NBA finals 6 times, won 4 championships, and set the record for regular seasons wins with 73.  Stephen Curry, the Warriors best player, also won the NBA Most Valuable Player award twice during that same span.  This success is generally regarded as a dynasty, a term used to describe a dominating team over a long period.\n\nHowever, this season the Warriors have struggled.  Despite winning the most recent NBA championship only 9 months ago, near the end of this regular season they are only a few games above .500.  Their current record is 42-38 as of today, which is only the 13th best record in the NBA out of 30 teams.\n\nThe reason for the drop is not clear.  The Warriors have the same starting lineup as last year with 4 All-Stars and when playing at Home their record is among the best in the league.  However, when playing on the road the Warriors have one of the worst records at 9-30.  A big factor in their road losses is lack of good defense, as opposing teams score considerably more points against the Warriors than when the Warriors play at home.  There seems to be a lack of focus and intensity from the Warriors players on defense in these away games and in the NBA, where the margin between winning and losing is very thin, that has seemed to make the difference.",

Nippon, the original Sino-Japanese reading of the characters, is favored for official uses, including on banknotes and postage stamps. Nihon is typically used in everyday speech and reflects shifts in Japanese phonology during the Edo period. The characters 日本 mean \"sun origin\", which is the source of the popular Western epithet \"Land of the Rising Sun\". The name \"Japan\" is based on Chinese pronunciations of 日本 and was introduced to European languages through early trade. In the 13th century, Marco Polo recorded the early Mandarin or Wu Chinese pronunciation of the characters 日本國 as Cipangu. The old Malay name for Japan, Japang or Japun, was borrowed from a southern coastal Chinese dialect and encountered by Portuguese traders in Southeast Asia, who brought the word to Europe in the early 16th century.

Cook for a few minutes before flipping to fully cook the egg.  This method is most common when preparing an egg sandwich such as a bacon egg and cheese, or a sausage egg and cheese. You can also scramble eggs in a pot or pan. To do this you whisk a few eggs in a bowl with some milk, could be any kind of milk like skim milk or a dairy free milk like almond milk. Preheat the stove to medium heat and warm the pot or pan while you do this. Then pour the eggs into the pan and continually stir the eggs, scraping the bottom of the pan to ensure the eggs are fluffy. You can also poach an egg by cracking an egg into boiling water. Lastly, you can make a hardboiled egg by putting a desired number of eggs in a pot of water before placing on the stove. Once on the stove bring to a boil for 7-8 minutes.",

However, there is evidence for three possible separate domestications of the avocado, resulting in the currently recognized Mexican (aoacatl), Guatemalan (quilaoacatl), and West Indian (tlacacolaocatl) landraces. The Mexican and Guatemalan landraces originated in the highlands of those countries, while the West Indian landrace is a lowland variety that ranges from Guatemala, Costa Rica, Colombia, Ecuador to Peru, achieving a wide range through human agency before the arrival of the Europeans. The three separate landraces were most likely to have already intermingled in pre-Columbian America and were described in the Florentine Codex.\n\nThe earliest residents of northern coastal Peru were living in temporary camps in an ancient wetland and eating avocados, along with chilies, mollusks, sharks, birds, and sea lions. The oldest discovery of an avocado pit comes from Coxcatlan Cave, dating from around 9,000 to 10,000 years ago. Other caves in the Tehuacan Valley from around the same time period also show early evidence for the presence and consumption of avocado. There is evidence for avocado use at Norte Chico civilization sites in Peru by at least 3,200 years ago and at Caballo Muerto in Peru from around 3,800 to 4,500 years ago.",

Viceroy Linlithgow remarked the movement to be \"by far the most serious rebellion since 1857\".\n\nThe All India Congress Committee launched a mass protest demanding what Gandhi called \"An Orderly British Withdrawal\" from India. Even though it was at war, the British were prepared to act. Almost the entire leadership of the Indian National Congress was imprisoned without trial within hours of Gandhi's speech. Most spent the rest of the war in prison and out of contact with the masses. The British had the support of the Viceroy's Council, of the All India Muslim League, the Hindu Mahasabha, the princely states, the Indian Imperial Police, the British Indian Army, and the Indian Civil Service. Many Indian businessmen profiting from heavy wartime spending did not support the Quit India Movement. The major outside support came from the Americans, as President Franklin D. Roosevelt pressured Prime Minister Winston Churchill to give in to some of the Indian demands.\n\nVarious violent incidents took place around the country against the British regime.

You know how everything around us is made of little components called atoms, right? The centers of these atoms, called the nuclei, are themselves made of particles, called protons and neutrons. These particles are super tiny, hundreds of times smaller than the atoms themselves! Anyway, the particles in the nucleus are stuck firmly together, but if disturbed by a high-energy particle, the nucleus can split apart. When it does that, it releases a lot of energy as light and heat. This splitting of the nucleus is called fission.\n\nIn some materials, each nucleus that splits also releases more loose particles, typically neutrons, that can hit other atoms, and this leads to what's called a chain reaction: one atom splitting can cause others to do so, and keep releasing more energy. If left uncontrolled in a dense enough material, this leads to an atomic explosion, which is very bad. Definitely don't try that at home! In fact don't try anything else at home. But if controlled with the right amount of moderating material, this type of reaction can give rise to a continuous and cheap source of energy, as used in nuclear power plants. Some countries get most of their energy today from nuclear fission.\n\nThe craziest thing about nuclear fission is that it was only discovered and put into use starting in the 1930s. It's such a new finding, and it's totally changed the world. Science rules!",

        "evidence": "Users of photo-sharing websites such as Flickr often provide short textual descriptions in the form of tags to help others find the images. With the availability of GPS systems in current electronic devices such as smartphones, latitude and longitude coordinates are nowadays commonly made available as well. The tags associated with such georeferenced photos often describe the location where these photos were taken, and Flickr can thus be regarded as a source of environmental information. The use of Flickr for modelling urban environments has already received considerable attention. For instance, various approaches have been proposed for modelling urban regions BIBREF0 , and for identifying points-of-interest BIBREF1 and itineraries BIBREF2 , BIBREF3 . However, the usefulness of Flickr for characterizing the natural environment, which is the focus of this paper, is less well-understood.\nMany recent studies have highlighted that Flickr tags capture valuable ecological information, which can be used as a complementary source to more traditional sources. To date, however, ecologists have mostly used social media to conduct manual evaluations of image content with little automated exploitation of the associated tags BIBREF4 , BIBREF5 , BIBREF6 . One recent exception is BIBREF7 , where bag-of-words representations derived from Flickr tags were found to give promising result for predicting a range of different environemental phenomena.\nOur main hypothesis in this paper is that by using vector space embeddings instead of bag-of-words representations, the ecological information which is implicitly captured by Flickr tags can be utilized in a more effective way. Vector space embeddings are representations in which the objects from a given domain are encoded using relatively low-dimensional vectors. They have proven useful in natural language processing, especially for encoding word meaning BIBREF8 , BIBREF9 , and in machine learning more generally. In this paper, we are interested in the use of such representations for modelling geographic locations. Our main motivation for using vector space embeddings is that they allow us to integrate the textual information we get from Flickr with available structured information in a very natural way. To this end, we rely on an adaptation of the GloVe word embedding model BIBREF9 , but rather than learning word vectors, we learn vectors representing locations. Similar to how the representation of a word in GloVe is determined by the context words surrounding it, the representation of a location in our model is determined by the tags of the photos that have been taken near that location. To incorporate numerical features from structured environmental datasets (e.g. average temperature), we associate with each such feature a linear mapping that can be used to predict that feature from a given location vector. This is inspired by the fact that salient properties of a given domain can often be modelled as directions in vector space embeddings BIBREF10 , BIBREF11 , BIBREF12 . Finally, evidence from categorical datasets (e.g. land cover types) is taken into account by requiring that locations belonging to the same category are represented using similar vectors, similar to how semantic types are sometimes modelled in the context of knowledge graph embedding BIBREF13 .\nWhile our point-of-departure is a standard word embedding model, we found that the off-the-shelf GloVe model performed surprisingly poorly, meaning that a number of modifications are needed to achieve good results. Our main findings are as follows. First, given that the number of tags associated with a given location can be quite small, it is important to apply some kind of spatial smoothing, i.e. the importance of a given tag for a given location should not only depend on the occurrences of the tag at that location, but also on its occurrences at nearby locations. To this end, we use a formulation which is based on spatially smoothed version of pointwise mutual information. Second, given the wide diversity in the kind of information that is covered by Flickr tags, we find that term selection is in some cases critical to obtain vector spaces that capture the relevant aspects of geographic locations. For instance, many tags on Flickr refer to photography related terms, which we would normally not want to affect the vector representation of a given location. Finally, even with these modifications, vector space embeddings learned from Flickr tags alone are sometimes outperformed by bag-of-words representations. However, our vector space embeddings lead to substantially better predictions in cases where structured (scientific) information is also taken into account. In this sense, the main value of using vector space embeddings in this context is not so much about abstracting away from specific tag usages, but rather about the fact that such representations allow us to integrate numerical and categorical features in a much more natural way than is possible with bag-of-words representations.\nThe remainder of this paper is organized as follows. In the next section, we provide a discussion of existing work. Section SECREF3 then presents our model for embedding geographic locations from Flickr tags and structured data. Next, in Section SECREF4 we provide a detailed discussion about the experimental results. Finally, Section SECREF5 summarizes our conclusions.\nSecond, given the wide diversity in the kind of information that is covered by Flickr tags, we find that term selection is in some cases critical to obtain vector spaces that capture the relevant aspects of geographic locations.",

        "answer": "It is a novel adversarial training framework which is used to deal with the instability issue of training GANs for text generation.",
        "evidence": "Natural text generation, as a key task in NLP, has been advanced substantially thanks to the flourish of neural models BIBREF0 , BIBREF1 . Typical frameworks such as sequence-to-sequence (seq2seq) have been applied to various generation tasks, including machine translation BIBREF2 and dialogue generation BIBREF3 . The standard paradigm to train such neural models is maximum likelihood estimation (MLE), which maximizes the log-likelihood of observing each word in the text given the ground-truth proceeding context BIBREF4 .\nAlthough widely used, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 : during test, the model sequentially predicts the next word conditioned on its previous generated words while during training conditioned on ground-truth words. To tackle this problem, generative adversarial networks (GAN) with reinforcement learning (RL) training approaches have been introduced to text generation tasks BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , where the discriminator is trained to distinguish real and generated text samples to provide reward signals for the generator, and the generator is optimized via policy gradient BIBREF7 .\nHowever, recent studies have shown that potential issues of training GANs on discrete data are more severe than exposure bias BIBREF14 , BIBREF15 . One of the fundamental issues when generating discrete text samples with GANs is training instability. Updating the generator with policy gradient always leads to an unstable training process because it's difficult for the generator to derive positive and stable reward signals from the discriminator even with careful pre-training BIBREF8 . As a result, the generator gets lost due to the high variance of reward signals and the training process may finally collapse BIBREF16 .\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation. At each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples. Then, inspired by reward augmented maximum likelihood (RAML) BIBREF17 , the generator is updated on the samples acquired from a stationary distribution with maximum likelihood estimation (MLE), weighted by the discriminator's rewards. This stationary distribution is designed to guarantee that training samples are surrounding the real data, thus the exploration space of our generator is indeed restricted by the MLE training objective, resulting in more stable training. Compared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient. Our contributions are mainly as follows:\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation.",

However, the structure of gender bias in vector space remains largely intact, and the new vectors still evince indirect bias: associations which result from gender bias between not explicitly gendered words, for example a possible association between football and business resulting from their mutual association with explicitly masculine words BIBREF4. In this paper we continue the work of BIBREF4, and show that another paradigm for gender bias mitigation proposed by BIBREF5, Counterfactual Data Augmentation (CDA), is also unable to mitigate indirect bias. We also show, using a new test we describe (non-biased gender analogies), that WED might be removing too much gender information, casting further doubt on its operationalisation of gender bias as a linear subspace.\nTo improve CDA we make two proposals. The first, Counterfactual Data Substitution (CDS), is designed to avoid text duplication in favour of substitution. The second, the Names Intervention, is a method which can be applied to either CDA or CDS, and treats bias inherent in first names. It does so using a novel name pairing strategy that accounts for both name frequency and gender-specificity. Using our improvements, the clusters of the most biased words exhibit a reduction of cluster purity by an average of 49% across both corpora following treatment, thereby offering a partial solution to the problem of indirect bias as formalised by BIBREF4.

        "answer": "The authors propose a classification framework based on a multi-layer formulation of Twitter diffusion networks.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks.",

        "answer": "Poor.",
        "evidence": "The task of generating natural language descriptions of structured data (such as tables) BIBREF2 , BIBREF3 , BIBREF4 has seen a growth in interest with the rise of sequence to sequence models that provide an easy way of encoding tables and generating text from them BIBREF0 , BIBREF1 , BIBREF5 , BIBREF6 .\nFor text generation tasks, the only gold standard metric is to show the output to humans for judging its quality, but this is too expensive to apply repeatedly anytime small modifications are made to a system. Hence, automatic metrics that compare the generated text to one or more reference texts are routinely used to compare models BIBREF7 . For table-to-text generation, automatic evaluation has largely relied on BLEU BIBREF8 and ROUGE BIBREF9 . The underlying assumption behind these metrics is that the reference text is gold-standard, i.e., it is the ideal target text that a system should generate. In practice, however, when datasets are collected automatically and heuristically, the reference texts are often not ideal. Figure FIGREF2 shows an example from the WikiBio dataset BIBREF0 . Here the reference contains extra information which no system can be expected to produce given only the associated table. We call such reference texts divergent from the table.\nWe show that existing automatic metrics, including BLEU, correlate poorly with human judgments when the evaluation sets contain divergent references (§ SECREF36 ). For many table-to-text generation tasks, the tables themselves are in a pseudo-natural language format (e.g., WikiBio, WebNLG BIBREF6 , and E2E-NLG BIBREF10 ). In such cases we propose to compare the generated text to the underlying table as well to improve evaluation. We develop a new metric, PARENT (Precision And Recall of Entailed N-grams from the Table) (§ SECREF3 ). When computing precision, PARENT effectively uses a union of the reference and the table, to reward correct information missing from the reference. When computing recall, it uses an intersection of the reference and the table, to ignore extra incorrect information in the reference. The union and intersection are computed with the help of an entailment model to decide if a text n-gram is entailed by the table. We show that this method is more effective than using the table as an additional reference. Our main contributions are:\nWe show that existing automatic metrics, including BLEU, correlate poorly with human judgments when the evaluation sets contain divergent references (§5.4).",

Long term users have seen Office evolve from its early days when it was installed on Windows machines to the relatively new Office 365 that is deployed online.  The key products in the Microsoft Office suite used by enterprises have been Word, Excel and Powerpoint. Google Docs is also an enterprise offering that consists of Docs, Sheets and Slides - these map to the corresponding Microsoft Office suite products listed.  Users who have been on Microsoft Office for many years find the move to Google Docs difficult.  This is because the commands across Google Docs are quite different to Office and one needs to spend time searching for MS office equivalent commands.  For example, the keyboard shortcut command to insert a freeze pane in windows excel is not the same in Google Sheets.  Formulae in cells and data analysis in Sheets is also different in sheets when compared to Excel. While it takes some time to unlearn commands and learn new ones as one moves from Microsoft Office to Google Docs, once one has spent some time working with Google Docs it starts to get easier.  And features such as ease of collaboration, never losing any content ever again, being able to work on the go from anywhere become the norm.

Here the context of the word INLINEFORM1 will be the original context ( INLINEFORM2 ) and any equations ( INLINEFORM3 ) that are in a possibly larger window around it.

Although REM stands for \"rapid eye movement\", this mode of sleep has many other aspects, including virtual paralysis of the body. Dreams are a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems; these are vital processes that maintain mood, memory, and cognitive function, and play a large role in the function of the endocrine and immune systems.

Rather than testing a model's ability to translate, it is a method to test a model's ability to discriminate between given good and bad translations.\nWe exploit the fact that NMT systems are in fact language models of the target language, conditioned on source text. Like language models, NMT systems can be used to compute a model score (the negative log probability) for an existing translation. Contrastive evaluation, then, means to compare the model score of two pairs of inputs: INLINEFORM0 and INLINEFORM1 . If the model score of the actual reference translation is higher, we assume that this model can detect wrong pronoun translations.\nHowever, this does not mean that systems actually produce the reference translation when given the source sentence for translation. An entirely different target sequence might rank higher in the system's beam during decoding. The only conclusion permitted by contrastive evaluation is whether or not the reference translation is more probable than a contrastive variant.\nIf the model score of the reference is indeed higher, we refer to this outcome as a “correct decision” by the model. The model's decision is only correct if the reference translation has a higher score than any contrastive translation. In our evaluation, we aggregate model decisions on the whole test set and report the overall percentage of correct decisions as accuracy.\nDuring scoring, the model is provided with reference translations as target context, while during translation, the model needs to predict the full sequence. It is an open question to what extent performance deteriorates when context is itself predicted, and thus noisy. We highlight that the same problem arises for sentence-level NMT, and has been addressed with alternative training strategies BIBREF27 .\nThe only conclusion permitted by contrastive evaluation is whether or not the reference translation is more probable than a contrastive variant.",

Having fallen ill on an embassy to the Hague, he obtained his discharge and died at Berlin in 1699.\n\nHe wrote verse in a restrained, sober style.  He was considered as one of the poets who “produced verse that was specifically aimed at entertaining and flattering princes and high courtiers.” Although he liked making verse in many languages, he never published any of them. Canitz's poems (Nebenstunden unterschiedener Gedichte), which did not appear until after his death (1700), are for the most part dry and stilted imitations of French and Latin models, but they formed a healthy contrast to the coarseness and bombast of the later Silesian poets.\n\nA complete edition of Canitz's poems was published by U.

        "question": "What architecture do they use in the generative component of their model?",
        "answer": "Encoder-decoder (HRED) architecture.",
        "evidence": "We now describe our general model for forecasting future conversational events. Our model integrates two components: (a) a generative dialog model that learns to represent conversational dynamics in an unsupervised fashion; and (b) a supervised component that fine-tunes this representation to forecast future events. Figure FIGREF13 provides an overview of the proposed architecture, henceforth CRAFT (Conversational Recurrent Architecture for ForecasTing).\nTerminology. For modeling purposes, we treat a conversation as a sequence of $N$ comments $C = \\lbrace c_1,\\dots ,c_N\\rbrace $. Each comment, in turn, is a sequence of tokens, where the number of tokens may vary from comment to comment. For the $n$-th comment ($1 \\le n \\le N)$, we let $M_n$ denote the number of tokens. Then, a comment $c_n$ can be represented as a sequence of $M_n$ tokens: $c_n = \\lbrace w_1,\\dots ,w_{M_n}\\rbrace $.\nGenerative component. For the generative component of our model, we use a hierarchical recurrent encoder-decoder (HRED) architecture BIBREF60, a modified version of the popular sequence-to-sequence (seq2seq) architecture BIBREF61 designed to account for dependencies between consecutive inputs. BIBREF23 showed that HRED can successfully model conversational context by encoding the temporal structure of previously seen comments, making it an ideal fit for our use case. Here, we provide a high-level summary of the HRED architecture, deferring deeper technical discussion to BIBREF60 and BIBREF23.\nAn HRED dialog model consists of three components: an utterance encoder, a context encoder, and a decoder. The utterance encoder is responsible for generating semantic vector representations of comments. It consists of a recurrent neural network (RNN) that reads a comment token-by-token, and on each token $w_m$ updates a hidden state $h^{\\text{enc}}$ based on the current token and the previous hidden state:\nwhere $f^{\\text{RNN}}$ is a nonlinear gating function (our implementation uses GRU BIBREF62). The final hidden state $h^{\\text{enc}}_M$ can be viewed as a vector encoding of the entire comment.\nRunning the encoder on each comment $c_n$ results in a sequence of $N$ vector encodings. A second encoder, the context encoder, is then run over this sequence:\nEach hidden state $h^{\\text{con}}_n$ can then be viewed as an encoding of the full conversational context up to and including the $n$-th comment. To generate a response to comment $n$, the context encoding $h^{\\text{con}}_n$ is used to initialize the hidden state $h^{\\text{dec}}_{0}$ of a decoder RNN. The decoder produces a response token by token using the following recurrence:\nwhere $f^{\\text{out}}$ is some function that outputs a probability distribution over words; we implement this using a simple feedforward layer. In our implementation, we further augment the decoder with attention BIBREF63, BIBREF64 over context encoder states to help capture long-term inter-comment dependencies. This generative component can be pre-trained using unlabeled conversational data.\nPrediction component. Given a pre-trained HRED dialog model, we aim to extend the model to predict from the conversational context whether the to-be-forecasted event will occur. Our predictor consists of a multilayer perceptron (MLP) with 3 fully-connected layers, leaky ReLU activations between layers, and sigmoid activation for output. For each comment $c_n$, the predictor takes as input the context encoding $h^{\\text{con}}_n$ and forwards it through the MLP layers, resulting in an output score that is interpreted as a probability $p_{\\text{event}}(c_{n+1})$ that the to-be-forecasted event will happen (e.g., that the conversation will derail).\nTraining the predictive component starts by initializing the weights of the encoders to the values learned in pre-training. The main training loop then works as follows: for each positive sample—i.e., a conversation containing an instance of the to-be-forecasted event (e.g., derailment) at comment $c_e$—we feed the context $c_1,\\dots ,c_{e-1}$ through the encoder and classifier, and compute cross-entropy loss between the classifier output and expected output of 1. Similarly, for each negative sample—i.e., a conversation where none of the comments exhibit the to-be-forecasted event and that ends with $c_N$—we feed the context $c_1,\\dots ,c_{N-1}$ through the model and compute loss against an expected output of 0.\nNote that the parameters of the generative component are not held fixed during this process; instead, backpropagation is allowed to go all the way through the encoder layers. This process, known as fine-tuning, reshapes the representation learned during pre-training to be more directly useful to prediction BIBREF55.\nWe implement the model and training code using PyTorch, and we are publicly releasing our implementation and the trained models together with the data as part of ConvoKit.\n\nGenerative component. For the generative component of our model, we use a hierarchical recurrent encoder-decoder (HRED) architecture (Sordoni et al., 2015a), a modified version of the popular sequence-to-sequence (seq2seq) architecture (Sutskever et al., 2014) designed to account for dependencies between consecutive inputs.",

        "evidence": "The goal of an language model is to assign meaningful probabilities to a sequence of words. Given a set of tokens $\\mathbf {X}=(x_1,....,x_T)$, where $T$ is the length of a sequence, our task is to estimate the joint conditional probability $P(\\mathbf {X})$ which is\nwere $(x_{1}, \\ldots , x_{i-1})$ is the context. An Intrinsic evaluation of the performance of Language Models is perplexity (PPL) which is defined as the inverse probability of the set of the tokens and taking the $T^{th}$ root were $T$ is the number of tokens\nIn our two approaches we use transformer based architectures: BERT and Transformer-XL as mentioned before. Calculating the auto-regressive $P(\\mathbf {X})$ for the transformer-XL is quite straight-forward as the model is unidirectional but it doesn't factorize the same way for a bi-directional model like BERT.\nBERT's bi-directional context poses a problem for us to calculate an auto-regressive joint probability. A simple fix could be that we mask all the tokens $\\mathbf {x}_{>i}$ and we calculate the conditional factors as we do for an unidirectional model. By doing so though, we loose upon the advantage of bi-directional context the BERT model enables. We propose an approximation of the joint probability as,\nThis type of approximations has been previously explored with Bi-directional RNN LM's BIBREF9 but not for deep transformer models. We therefore, define a pseudo-perplexity score from the above approximated joint probability.\nThe original BERT has two training objectives: 'Masked language modelling', in which you mask input tokens randomly and then predict the masked tokens using the left and right context. Additionally, there is the 'next sentence prediction' task that jointly trains text-pair representations. For training the Masked language model the original BERT used Byte Pair Encoding (BPE) BIBREF10 for subword tokenization BIBREF11.For example the rare word \"unaffable\" to be split up into more frequent subwords such as [\"un\", \"##aff\", \"##able\"]. To remain consistent with experiments performed with LSTM's we use the morfessor for the subword tokenization in the Finnish Language. In Addition, we also apply boundary markers as in (Table TABREF7) and train two separate models using this distinction. We train with left-marked markings as the original BERT was trained with such a scheme and the left+right-marked as it was the previous SOTA with the Finnish Language. For the transformer-XL experiments, we just train with the left+right marked scheme.\nThe Next Sentence Prediction (NSP) is a binary classification task which predicts whether two segments follow each other in the original text. This pre-training task was proposed to further improve the performance on downstreaming tasks, like Natural Language Inference(NLI) but in reality removing the NSP loss matches or slightly improves the downstream task performance BIBREF12. In this paper, we have omitted the NSP task from the BERT pre-training procedure and changed the input from a SEGMENT-PAIR input to a SINGLE SEGMENT input. As seen in (Fig FIGREF8)\nTransformer-XL introduced the notion of recurrence in self-attention by caching the hidden state sequence to compute the hidden states of a new segment. It also introduces a novel relative positional embedding scheme and both of them combined address the issue of fixed context lengths. Transformer-XL as mentioned is a unidirectional deep transformer architecture, therefore the perplexity can be calculated as (Eq DISPLAY_FORM5). The only change is in the input format, were we use sub-word units rather than whole word units as Finnish is morphologically richer than English.\nThe only change is in the input format, were we use sub-word units rather than whole word units as Finnish is morphologically richer than English.",

        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents.",

Syntactic patterns BIBREF18 , BIBREF19 , BIBREF20 , BIBREF21 and syntactic dependencies BIBREF3 have been shown to improve performance, while syntactically or semantically important words are often expanding using Wordnet hypernyms or Unified Medical Language System categories (for the medical domain) to help mitigate sparsity BIBREF22 , BIBREF23 , BIBREF24 . Keyword identification helps identify specific terms useful for classification BIBREF25 , BIBREF3 , BIBREF26 . Similarly, named entity recognizers BIBREF6 , BIBREF27 or lists of semantically related words BIBREF6 , BIBREF24 can also be used to establish broad topics or entity categories and mitigate sparsity, as can word embeddings BIBREF28 , BIBREF29 . Here, we empirically demonstrate many of these existing methods do not transfer to the science domain.\nThe highest performing question classification systems tend to make use of customized rule-based pattern matching BIBREF30 , BIBREF7 , or a combination of rule-based and machine learning approaches BIBREF19 , at the expense of increased model construction time. A recent emphasis on learned methods has shown a large set of CNN BIBREF29 and LSTM BIBREF8 variants achieve similar accuracy on TREC question classification, with these models exhibiting at best small gains over simple term frequency models. These recent developments echo the observations of Roberts et al. BIBREF3 , who showed that existing methods beyond term frequency models failed to generalize to medical domain questions. Here we show that strong performance across multiple datasets is possible using a single learned model.\nDue to the cost involved in their construction, question classification datasets and classification taxonomies tend to be small, which can create methodological challenges. Roberts et al. BIBREF3 generated the next-largest dataset from TREC, containing 2,936 consumer health questions classified into 13 question categories. More recently, Wasim et al. BIBREF4 generated a small corpus of 780 biomedical domain questions organized into 88 categories. In the education domain, Godea et al. BIBREF5 collected a set of 1,155 classroom questions and organized these into 16 categories.

These low-level functions are used by other programs, so their authors can focus on the specific functionality they want to provide. Without the kernel, your computer is a very expensive doorstop. It has all of the features of a modern operating system: true multitasking, threads, virtual memory, shared libraries, demand loading, shared, copy-on-write executables, proper memory management, loadable device driver modules, video frame buffering, and TCP/IP networking.\n\nMost often, the name \"Linux\" is used to refer to the Linux Operating System. An OS includes the kernel, but also adds various utilities — the kinds of programs you need to get anything done. For example, it includes a shell (the program that provides a command prompt and lets you run programs), a program to copy files, a program to delete files, and many other odds and ends.

The VQA task has witnessed a significant progress in the recent years by the machine intelligence community. The aim of VQA is to develop a system to answer specific questions about an input image. The answer could be in any of the following forms: a word, a phrase, binary answer, multiple choice answer, or a fill in the blank answer. Agarwal et al. BIBREF0 presented a novel way of combining computer vision and natural language processing concepts of to achieve Visual Grounded Dialogue, a system mimicking the human understanding of the environment with the use of visual observation and language understanding.\nThe advancements in the field of deep learning have certainly helped to develop systems for the task of Image Question Answering. Krizhevsky et al BIBREF1 proposed the AlexNet model, which created a revolution in the computer vision domain. The paper introduced the concept of Convolution Neural Networks (CNN) to the mainstream computer vision application. Later many authors have worked on CNN, which has resulted in robust, deep learning models like VGGNet BIBREF2, Inception BIBREF3, ResNet BIBREF4, and etc. Similarly, the recent advancements in natural language processing area based on deep learning have improved the text understanding prforance as well. The first major algorithm in the context of text processing is considered to be the Recurrent Neural Networks (RNN) BIBREF5 which introduced the concept of prior context for time series based data. This architecture helped the growth of machine text understanding which gave new boundaries to machine translation, text classification and contextual understanding. Another major breakthrough in the domain was the introduction of Long-Short Term Memory (LSTM) architecture BIBREF6 which improvised over the RNN by introducing a context cell which stores the prior relevant information.\nThe vanilla VQA model BIBREF0 used a combination of VGGNet BIBREF2 and LSTM BIBREF6. This model has been revised over the years, employing newer architectures and mathematical formulations. Along with this, many authors have worked on producing datasets for eliminating bias, strengthening the performance of the model by robust question-answer pairs which try to cover the various types of questions, testing the visual and language understanding of the system. In this survey, first we cover major datasets published for validating the Visual Question Answering task, such as VQA dataset BIBREF0, DAQUAR BIBREF7, Visual7W BIBREF8 and most recent datasets up to 2019 include Tally-QA BIBREF9 and KVQA BIBREF10.

Schemes include formal definitions or procedures, and often include examples, particularly for borderline cases. Next, coders are trained with the coding scheme, which typically involves interactive feedback. Training sometimes results in changes to the coding scheme, in which the first round becomes a pilot test. Then, annotators independently review at least a portion of the same items throughout the entire process, with a calculation of “inter-annotator agreement” or “inter-rater reliability.” Finally, there is a process of “reconciliation” for disagreements, which is sometimes by majority vote without discussion and other times discussion-based.\nCreating human-labeled training datasets for machine learning often looks like content analysis, a well-established methodology in the humanities and the social sciences (particularly literature, communication studies, and linguistics), which also has versions used in the life, ecological, and medical sciences.

We conduct experiments on multiple imbalanced training datasets artificially created from three benchmark image datasets CIFAR10, CIFAR100 and SVHN with diverse imbalanced distributions.

For Exp imbalance, the number of training examples of each class will be reduced according to an exponential function n = n i τ i , where i is the class index, n i is the number of training examples in the original training dataset for class i and τ ∈ (0, 1). We categorize half classes with most frequent example sizes in the imbalanced training dataset as well-represented classes and the remaining half classes as under-represented classes. For Step imbalance, we follow the similar process adopted in Section 2.1. Moreover, we denote imbalance ratio K as the ratio between training example sizes of the most frequent and least frequent class. We construct different imbalanced datasets \"Step-10\", \"Step-100\", \"Exp-10\" and \"Exp-100\", by adopting different imbalanced types (Step or Exp) with different imbalanced ratios (K = 10 or K = 100) to train models, and evaluate model's performance on the original uniformly distributed test datasets of CIFAR10, CIFAR100 and SVHN correspondingly.\nMore detailed information about imbalanced training sets can be found in Appendix A.5.\nBaseline methods. We implement several representative and state-of-the-art imbalanced learning methods (or their combinations) into adversarial training as baseline methods.

        "question": "What model did the authors use in their transfer learning approach?",
        "answer": "The pre-trained language model BERT.",
        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets.",

        "evidence": "Recently, chit-chat dialogue models have achieved improved performance in modelling a variety of conversational domains, including movie subtitles, Twitter chats and help forums BIBREF0, BIBREF1, BIBREF2, BIBREF3. These neural systems were used to model conversational dialogue via training on large chit-chat datasets such as the OpenSubtitles corpus, which contains generic dialogue conversations from movies BIBREF4. The datasets used do not have an explicit dialogue state to be modelled BIBREF5, but rather require the agent to learn the nuances of natural language in the context of casual peer-to-peer interaction.\nMany recent chit-chat systems BIBREF2, BIBREF3 attempt to introduce increased diversity into model responses. However, dialogue systems have also been known to suffer from a lack of coherence BIBREF0. Given an input message history, systems often have difficulty tracking important information such as professions and names BIBREF0. It would be of benefit to create a system which extracts relevant features from the input that indicate which responses would be most appropriate, and conditions on this stored information to select the appropriate response.\nA major problem with existing recurrent neural network (RNN) architectures is that these systems aggregate all input tokens into a state vector, which is passed to a decoder for generation of the final response, or in the case of a neural probabilistic language model BIBREF6, the state at each time step is used to predict the next token in the sequence. Ideally the size of the state should expand with the number of input tokens and should not lose important information about the input. However, RNN states are typically fixed sized, and for any chosen state size, there exists an input sequence length for which the RNN would not be able to store all relevant details for a final response. In addition, the RNN state undergoes constant transformation at each computational step. This makes it difficult to maintain a persistent storage of information that remains constant over many time steps.\nThe introduction of attention mechanisms BIBREF7 has sparked a change in the current design of RNN architectures. Instead of relying fully on a fixed-sized state vector, an attention mechanism allows each decoder word prediction step to extract relevant information from past states through a key-value query mechanism. However, this mechanism connects every input token with all preceeding ones via a computational step, increasing the complexity of the calculation to $O(N^2)$ for an input sequence size N. In the ideal case, the mapping of input conversation history to output response would have a computational complexity of $O(N)$. For this reason, it is desirable to have an information retrieval system that is both scale-able, but not proportional to input length.\nWe study the impact of accessible memory on response coherence by constructing a memory-augmented dialogue system. The motivation is that it would be beneficial to store details of the conversational history in a more permanent memory structure, instead of being captured inside a fixed-sized RNN hidden state. Our proposed system is able to both read and write to a persistent memory module after reading each input utterance. As such, it has access to a stable representation of the input message history when formulating a final response. We explore two distinct memory architectures with different properties, and compare their differences and benefits. We evaluate our proposed memory systems using perplexity evaluation, and compare them to competitive baselines.\nWe explore two distinct memory architectures with different properties, and compare their differences and benefits.",

Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), \"light\", and synthesis (σύνθεσις), \"putting together\". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.\n\nAlthough photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the \"energy currency\" of cells.",

Instead of focusing on the previously studied game environments BIBREF5, BIBREF6, the dataset considers a more realistic setup: negotiating the price of products listed on Craigslist. The dataset consists of 6682 dialogues between a buyer and a seller who converse in natural language to negotiate the price of a given product (sample in Table TABREF1). In total, 1402 product ad postings were scraped from Craigslist, belonging to six categories: phones, bikes, housing, furniture, car and electronics. Each ad posting contains details such as Product Title, Category Type and a Listing Price. Moreover, a secret target price is also pre-decided for the buyer. The final price after the agreement is called the Agreed Price, which we aim to predict.\nDefining the problem: Say we are provided with a product scenario $S$, a tuple: (Category, Title, Listing Price, Target Price). Define the interactions between a buyer and seller using a sequence of $n$ events $E_n:<e_{1}, e_{2}, ..., e_{n}>$, where $e_{i}$ occurs before $e_{j}$ iff $i<j$. Event $e_{i}$ is also a tuple: (Initiator, Type, Data).

Nearly $80\\%$ of events in CB dataset are of type `message', each consisting a textual message as Data. An offer is usually made and accepted at the end of each negotiation. Since the offers directly contain the agreed price (which we want to predict), we only consider `message' events in our models. Given the scenario $S$ and first $n$ events $E_n$, our problem is then to learn the function $f_{n}$: $A = f_{n}(S, E_n)$ where $A$ refers to the final agreed price between the two negotiating parties.\n\nThe dataset consists of 6682 dialogues (9.2 turns on average) between buyers and sellers who converse to negotiate the price of a given product.",

Lakshmi quarreled with Vishnu, as she felt that Bhrigu insulted her indirectly by hitting Vishnu on his chest where she lived, and thus left Vaikuntha.\n\nShe settled on earth in disguise as a young-sage like boy in the ancient city of Karvir, and meditated the name of Vishnu (Regarded by adherents to be the site of the Mahalakshmi temple). Vishnu soon arrived on earth, searching for his consort. He failed to find her, and instead settled on the Seshachalam hills. This happened to be the spot in Tirupati where Varaha had rested and taught Karma Yoga to the people till the beginning of Kali Yuga, after having rescuing Bhudevi from the wicked Hiranyaksha. Vishnu sat inside an anthill in his disguise, which was situated under a tamarind tree, and started chanting the name of his wife, Mahalakshmi.\n\nThe whole earth became gloomy. On the request of Parvati and Saraswati, Shiva and Brahma incarnated as a cow and a calf respectively, in the Chola kingdom. This cow and calf were being grazed daily by a shepherd of Chola kingdom in the Seshachalam hills. Everyday, the cow used to pour her milk into the anthill to lessen the thirst of Vishnu. Due to this, the cow and calf became pale and unhealthy. The shepherd noticed this, and felt that something was awry. The next day, the shepherd took the animals for grazing, and as was the custom, the cow poured milk into the anthill. The shepherd saw this act, and he threw an axe (parasu) on the cow and calf. Vishnu noticed, and in order to protect them, Vishnu arose from the anthill and the axe hit his own forehead (the blood poured as his namam on his head). An enraged Vishnu cursed the shepherd that he would die immediately, and the latter succumbed to the blow of his own axe. This news reached the Chola king. The ruler suspected the absence of the shepherd. He went near the grazing field, and was surprised to see the corpse of the shepherd. He went to the grazing field, where the cows were offering their milk to Vishnu. However, Vishnu was in disguise, and so the king could not identify him. The king strung his arrow, believing that the milk should serve the kingdom rather than the boy he saw. Vishnu, once again, emerged, and grew enormous, stopped the arrows from passing further and he cursed the king for not maintaining the dharma of his kingdom. The king repented and surrendered at the deity's feet. Unlike the shepherd, the king had realised his mistake, which pleased Vishnu, and hence presented him with the boon that he would marry the king's daughter in his next birth.\n\nIn his next birth, Vishnu incarnated as Srinivasa, to a woman named Vakuladevi. It is said that in the Dvapara Yuga, Krishna presented Yashoda with a boon that he would be born to the former in the Kali Yuga. Vakuladevi is regarded as the reincarnation of Yashoda. Meanwhile, the goddess Lakshmi was born at the palace of Akasha Raja, the next birth of the Chola king. Srinivasa was a forest-dweller. One day, he met a beautiful girl named Padmavati, the princess of the Chola dynasty. Padmavati fell in love with Srinivasa , and decided to marry him. According to the boon of Vishnu to the Chola king in their previous births, Srinivasa has to marry Padmavati, princess of Chola dynasty. For the marriage expenses, Srinivasa borrowed riches from Kubera, and promised to repay the loan with interest at the end of the Kali Yuga.",

Offensive language can be categorized as: Vulgar, which include explicit and rude sexual references, Pornographic, and Hateful, which includes offensive remarks concerning people’s race, religion, country, etc. BIBREF14. Prior works have concentrated on building annotated corpora and training classification models. Concerning corpora, hatespeechdata.com attempts to maintain an updated list of hate speech corpora for multiple languages including Arabic and English. Further, SemEval 2019 ran an evaluation task targeted at detecting offensive language, which focused exclusively on English BIBREF15. As for classification models, most studies used supervised classification at either word level BIBREF10, character sequence level BIBREF11, and word embeddings BIBREF9. The studies used different classification techniques including using Naïve Bayes BIBREF10, SVM BIBREF11, and deep learning BIBREF6, BIBREF7, BIBREF12 classification. The accuracy of the aforementioned system ranged between 76% and 90%. Earlier work looked at the use of sentiment words as features as well as contextual features BIBREF13.\nThe work on Arabic offensive language detection is relatively nascent BIBREF16, BIBREF17, BIBREF18, BIBREF19, BIBREF5.

Though word segmentation (or stemming) is quite accurate for MSA BIBREF20, with accuracy approaching 99%, dialectal segmentation is not sufficiently reliable, with accuracy ranging between 91-95% for different dialects BIBREF21. Since dialectal Arabic is ubiquitous in Arabic tweets and many tweets have creative spellings of words, recent work on Arabic offensive language detection used character-level models BIBREF5.\nArabic is a morphologically rich language with a standard variety called Modern Standard Arabic (MSA), which is typically used in formal communication, and many dialectal varieties that differ from MSA in lexical selection, morphology, phonology, and syntactic structures.",

        "question": "Do the LSTMs outperform than the more recent models?",
        "answer": "Yes.",
        "evidence": "The scientific process by which the deep learning research community operates is guided by empirical studies that evaluate the relative quality of models. Complicating matters, the measured performance of a model depends not only on its architecture (and data), but it can strongly depend on hyperparameter values that affect learning, regularisation, and capacity. This hyperparameter dependence is an often inadequately controlled source of variation in experiments, which creates a risk that empirically unsound claims will be reported.\nIn this paper, we use a black-box hyperparameter optimisation technique to control for hyperparameter effects while comparing the relative performance of language modelling architectures based on LSTMs, Recurrent Highway Networks BIBREF0 and NAS BIBREF1 . We specify flexible, parameterised model families with the ability to adjust embedding and recurrent cell sizes for a given parameter budget and with fine grain control over regularisation and learning hyperparameters.\nOnce hyperparameters have been properly controlled for, we find that LSTMs outperform the more recent models, contra the published claims. Our result is therefore a demonstration that replication failures can happen due to poorly controlled hyperparameter variation, and this paper joins other recent papers in warning of the under-acknowledged existence of replication failure in deep learning BIBREF2 , BIBREF3 . However, we do show that careful controls are possible, albeit at considerable computational cost.\nSeveral remarks can be made in light of these results. First, as (conditional) language models serve as the central building block of many tasks, including machine translation, there is little reason to expect that the problem of unreliable evaluation is unique to the tasks discussed here. However, in machine translation, carefully controlling for hyperparameter effects would be substantially more expensive because standard datasets are much larger. Second, the research community should strive for more consensus about appropriate experimental methodology that balances costs of careful experimentation with the risks associated with false claims. Finally, more attention should be paid to hyperparameter sensitivity. Models that introduce many new hyperparameters or which perform well only in narrow ranges of hyperparameter settings should be identified as such as part of standard publication practice.\nOnce hyperparameters have been properly controlled for, we find that LSTMs outperform the more recent models, contra the published claims.",

Especially, twitter has attracted a lot of attention from researchers for studying the public sentiments. Stock market prediction on the basis of public sentiments expressed on twitter has been an intriguing field of research. Previous studies have concluded that the aggregate public mood collected from twitter may well be correlated with Dow Jones Industrial Average Index (DJIA). The thesis of this work is to observe how well the changes in stock prices of a company, the rises and falls, are correlated with the public opinions being expressed in tweets about that company. Understanding author's opinion from a piece of text is the objective of sentiment analysis. The present paper have employed two different textual representations, Word2vec and N-gram, for analyzing the public sentiments in tweets. In this paper, we have applied sentiment analysis and supervised machine learning principles to the tweets extracted from twitter and analyze the correlation between stock market movements of a company and sentiments in tweets. In an elaborate way, positive news and tweets in social media about a company would definitely encourage people to invest in the stocks of that company and as a result the stock price of that company would increase.

        "evidence": "According to the types of intentions, conversational systems can be classified into two categories: a) goal-driven or task oriented, and b) non-goal-driven or end-to-end systems.\nIn a goal-driven system, the main objective is to interact with the user so that back-end tasks, which are application specific, are executed by a supporting system. As an example of application we can cite technical support systems, for instance air ticket booking systems, where the conversation system must interact with the user until all the required information is known, such as origin, destination, departure date and return date, and the supporting system must book the ticket. The most widely used approaches for developing these systems are Partially-observed Decision Processes (POMDP) BIBREF30 , Hidden Markov Models (HMM) BIBREF29 , and more recently, Memory Networks BIBREF28 . Given that these approaches are data-oriented, a major issue is to collect a large corpora of annotated task-specific dialogs. For this reason, it is not trivial to transfer the knowledge from one to domain to another. In addition, it might be difficult to scale up to larger sets of tasks.\nNon-goal-driven systems (also sometimes called reactive systems), on the other hand, generate utterances in accordance to user input, e.g. language learning tools or computer games characters. These systems have become more popular in recent years, mainly owning to the increase of popularity of Neural Networks, which is also a data-oriented approach. The most recent state of the art to develop such systems have employed Recurrent Neural Networs (RNN) BIBREF34 , Dynamic Context-Sensitive Generation BIBREF35 , and Memory Networks BIBREF36 , just to name a few. Nevertheless, probabilistic methods such as Hidden Topic Markov Models (HTMM) BIBREF37 have also been evaluated. Goal-driven approach can create both pro-active and reactive chatbots, while non-goal-driven approach creates reactive chatbots. In addition, they can serve as a tool to goal-driven systems as in BIBREF28 . That is, when trained on corpora of a goal-driven system, non-goal-driven systems can be used to simulate user interaction to then train goal-driven models.\nAccording to the types of intentions, conversational systems can be classified into two categories: a) goal-driven or task oriented, and b) non-goal-driven or end-to-end systems.",

        "answer": "The Debt Snowball and Debt Avalanche are two widely known methods of paying off debt. One is a mathematically faster way to pay off the debt; whereas, the alternative is slightly slower but is more psychologically motivating. This motivation is what helps the person reach their debt pay off goals. The following set of debts will be used as the basis for explaining each method:\n\nDebt A has a balance of $10,000 at a 4% interest rate. \nDebt B has a balance of $5,000 at a 10% interest rate.\nDebt C has a balance of $8,000 at a 24% interest rate. \n\nThe Debt Avalanche is typically the fastest and most cost effective way to pay off debt. The person makes minimum payments on all their debts and any extra goes towards the account with highest interest rate (Debt C in example above). Once that first balance is paid off, the person takes the payments from that and puts it all towards the second highest interest rate (Debt B). Repeat until all debts are paid.\n\nThe Debt Snowball is a method popularized by a personal finance expert, Dave Ramsey, in Step 2 of his 7 Baby Steps to building wealth. This method uses psychology by paying off the smallest balance first (Debt B above). The theory is that the feeling of quickly paying off a debt balance provides the motivation to stick with the program.

        "answer": "In finance, stock (also capital stock) consist of all the shares by which ownership of a corporation or company is divided. (Especially in American English, the word \"stocks\" is also used to refer to shares.) A single share of the stock means fractional ownership of the corporation in proportion to the total number of shares. This typically entitles the shareholder (stockholder) to that fraction of the company's earnings, proceeds from liquidation of assets (after discharge of all senior claims such as secured and unsecured debt), or voting power, often dividing these up in proportion to the amount of money each stockholder has invested. Not all stock is necessarily equal, as certain classes of stock may be issued for example without voting rights, with enhanced voting rights, or with a certain priority to receive profits or liquidation proceeds before or after other classes of shareholders.\n\nStock can be bought and sold privately or on stock exchanges, and such transactions are typically heavily regulated by governments to prevent fraud, protect investors, and benefit the larger economy. The stocks are deposited with the depositories in the electronic format also known as Demat account. As new shares are issued by a company, the ownership and rights of existing shareholders are diluted in return for cash to sustain or grow the business. Companies can also buy back stock, which often lets investors recoup the initial investment plus capital gains from subsequent rises in stock price. Stock options issued by many companies as part of employee compensation do not represent ownership, but represent the right to buy ownership at a future time at a specified price. This would represent a windfall to the employees if the option is exercised when the market price is higher than the promised price, since if they immediately sold the stock they would keep the difference (minus taxes).",

        "question": "Without quoting directly from the text, provide me with a summary of the James Webb Space Telescope?",
        "evidence": "The James Webb Space Telescope (JWST) is a space telescope currently conducting infrared astronomy. As the largest optical telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars, the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.\n\nThe U.S. National Aeronautics and Space Administration (NASA) led JWST's design and development and partnered with two main agencies: the European Space Agency (ESA) and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center (GSFC) in Maryland managed telescope development, while the Space Telescope Science Institute in Baltimore on the Homewood Campus of Johns Hopkins University currently operates JWST. The primary contractor for the project was Northrop Grumman. The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo programs.\n\nThe James Webb Space Telescope was launched on 25 December 2021 on an Ariane 5 rocket from Kourou, French Guiana, and arrived at the Sun–Earth L2 Lagrange point in January 2022. The first JWST image was released to the public via a press conference on 11 July 2022.\n\nJWST's primary mirror consists of 18 hexagonal mirror segments made of gold-plated beryllium, which combined create a 6.5-meter-diameter (21 ft) mirror, compared with Hubble's 2.4 m (7 ft 10 in). This gives JWST a light-collecting area of about 25 square meters, about six times that of Hubble. Unlike Hubble, which observes in the near ultraviolet and visible (0.1 to 0.8 μm), and near infrared (0.8–2.5 μm) spectra, JWST observes a lower frequency range, from long-wavelength visible light (red) through mid-infrared (0.6–28.3 μm). The telescope must be kept extremely cold, below 50 K (−223 °C; −370 °F), such that the infrared light emitted by the telescope itself does not interfere with the collected light. It is deployed in a solar orbit near the Sun–Earth L2 Lagrange point, about 1.5 million kilometers (930,000 mi) from Earth, where its five-layer sunshield protects it from warming by the Sun, Earth, and Moon.\n\nInitial designs for the telescope, then named the Next Generation Space Telescope, began in 1996. Two concept studies were commissioned in 1999, for a potential launch in 2007 and a US$1 billion budget. The program was plagued with enormous cost overruns and delays; a major redesign in 2005 led to the current approach, with construction completed in 2016 at a total cost of US$10 billion. The high-stakes nature of the launch and the telescope's complexity were remarked upon by the media, scientists, and engineers.",

The JWST has specialized instrumentation capable of detecting light at lower frequencies and longer wavelengths enabling it to detect light in the near to mid-infrared light spectrum range.\n\nThe design of JWST started in 1996 and was plagued with enormous cost overruns and delays culminating in a redesign in 2005 which lead to the current final design of the JWST.

We note that this is different from our model of soft interventions and results in slight degrading of the performance of our algorithm, but since we are using FCI-JCI123 as our benchmark, we adopt its setting.\nWe consider two environments and one intervention target for simplicity of the comparisons. We generate 30 Erdős-Rényi random DAGs. The probability of an edge being present in the random graphs is set to 2/p where p is the number of observed and latent variables. We report the precision and recall rates of both algorithms along with their runtimes in Table. While both methods have similar performance, there is a significant discrepancy in their runtime. More importantly, the runtime of FCI-JCI123 becomes prohibitive very quickly, even with graphs with as few as 40 nodes. In contrast, PreDITEr has a significantly lower runtime even though the considered setting (i.e., mechanism changes) is not the setting for which it is designed. All simulations are run on a computer with i7-4960HQ, 16GB 1600MHz RAM. We apply the PreDITEr algorithm to a real dataset with data from observational and multiple interventional settings. Since PreDITEr estimates the intervention targets and their corresponding parent-spouse sets for each pair of available settings, we combine the findings from each pair and yield a mixed graph estimate of the associated causal structure. Protein signaling data. We consider the dataset of, which is a standard benchmark in causal inference literature. The data is obtained from measurements of the proteins involved in T-4 cell signaling. The protein signaling network consists of 11 nodes. In each interventional setting, various drugs are injected into the cells to inhibit or activate different signaling proteins. The target proteins are considered sites of intervention. Data from observational and five interventional settings are provided. The true ground truth network is not exactly known, and the accepted ground truth has been updated over the years. Notably, it is represented by a DAG without latent confounders. We use the recent version of Ness et al., which consists of 16 edges, and use the preprocessed real data provided by.\nFigure shows the output of our algorithm. For a pair of nodes, if they are found to be in the parent-spouse sets of one another, they must be spouses, and we assign a bidirected edge. If only one of them lies in the parent-spouse set of the other node, it must be the parent, and we assign a directed edge to them. If we do not have either of the above results, the relationship can be either parent or spouse, and we denote it by → • on the graph. The recovered edges that are also present in the skeleton of the ground truth DAG are marked in blue. This result illustrates that even though our algorithm is designed for linear models, it has the potential to be applied to real datasets with non-linear models.\nWe run PreDITEr with a varying number of samples on graphs with varying sizes p. Figure 2 illustrates the target recovery performance. Specifically, it shows that our method recovers the intervention target with high F1 scores.

        "question": "What novel application did the authors explore?",
        "answer": "A novel application of capsule networks (CapsNet).",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization.",

Several time-locked stereotyped EEG responses to word-presentations -- known collectively as event-related potentials (ERPs) -- are thought to be markers for semantic or syntactic processes that take place during comprehension. However, the characterization of each individual ERP in terms of what features of a stream of language trigger the response remains controversial. Improving this characterization would make ERPs a more useful tool for studying language comprehension. We take a step towards better understanding the ERPs by fine-tuning a language model to predict them. This new approach to analysis shows for the first time that all of the ERPs are predictable from embeddings of a stream of language. Prior work has only found two of the ERPs to be predictable. In addition to this analysis, we examine which ERPs benefit from sharing parameters during joint training. We find that two pairs of ERPs previously identified in the literature as being related to each other benefit from joint training, while several other pairs of ERPs that benefit from joint training are suggestive of potential relationships. Extensions of this analysis that further examine what kinds of information in the model embeddings relate to each ERP have the potential to elucidate the processes involved in human language comprehension.\nSeveral time-locked stereotyped EEG responses to word-presentations – known collectively as event-related potentials (ERPs) – are thought to be markers for semantic or syntactic processes that take place during comprehension.",

        "question": "Are the conversational context and intervention responses critical in order to build generative models to automatically mitigate the spread of these types of conversations?",
        "answer": "Yes, they are.",
        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nDistinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses.",

        "question": "Who coined the phrase \"Bike-shedding\" and when?",
        "evidence": "The law of triviality is C. Northcote Parkinson's 1957 argument that people within an organization commonly or typically give disproportionate weight to trivial issues. Parkinson provides the example of a fictional committee whose job was to approve the plans for a nuclear power plant spending the majority of its time on discussions about relatively minor but easy-to-grasp issues, such as what materials to use for the staff bicycle shed, while neglecting the proposed design of the plant itself, which is far more important and a far more difficult and complex task.\n\nThe law has been applied to software development and other activities. The terms bicycle-shed effect, bike-shed effect, and bike-shedding were coined based on Parkinson's example; it was popularised in the Berkeley Software Distribution community by the Danish software developer Poul-Henning Kamp in 1999 and, due to that, has since become popular within the field of software development generally.\n\nArgument\n\nA bicycle shed\nThe concept was first presented as a corollary of his broader \"Parkinson's law\" spoof of management. He dramatizes this \"law of triviality\" with the example of a committee's deliberations on an atomic reactor, contrasting it to deliberations on a bicycle shed. As he put it: \"The time spent on any item of the agenda will be in inverse proportion to the sum [of money] involved.\" A reactor is so vastly expensive and complicated that an average person cannot understand it (see ambiguity aversion), so one assumes that those who work on it understand it. However, everyone can visualize a cheap, simple bicycle shed, so planning one can result in endless discussions because everyone involved wants to implement their own proposal and demonstrate personal contribution.\n\nAfter a suggestion of building something new for the community, like a bike shed, problems arise when everyone involved argues about the details. This is a metaphor indicating that it is not necessary to argue about every little feature based simply on having the knowledge to do so. Some people have commented that the amount of noise generated by a change is inversely proportional to the complexity of the change.\n\nThe law of triviality is supported by behavioural research. People tend to spend more time on small decisions than they should, and less time on big decisions than they should. A simple explanation is that during the process of making a decision, one has to assess whether enough information has been collected to make the decision. If people make mistakes about whether they have enough information, they will tend to stop too early for big decisions. The reason is that big decisions require collecting information for a long time. It leaves more time to make a mistake (and stop) before getting enough information. Conversely, for small decisions, where people should stop early, they may continue to ponder for too long by mistake.\n\nRelated principles and formulations \nThere are several other principles, well-known in specific problem domains, which express a similar sentiment.\n\nWadler's law, named for computer scientist Philip Wadler, is a principle which asserts that the bulk of discussion on programming-language design centers on syntax (which, for purposes of the argument, is considered a solved problem), as opposed to semantics.\n\nSayre's law is a more general principle, which holds (among other formulations) that \"In any dispute, the intensity of feeling is inversely proportional to the value of the issues at stake\"; many formulations of the principle focus on academia.",

        "question": "Given this article about the NSA's ANT catalog, Which hacking tools are used to infect the BIOS of computers or networking devices?",
        "evidence": "The ANT catalog (or TAO catalog) is a classified product catalog by the U.S. National Security Agency (NSA) of which the version written in 2008–2009 was published by German news magazine Der Spiegel in December 2013. Forty-nine catalog pages with pictures, diagrams and descriptions of espionage devices and spying software were published. The items are available to the Tailored Access Operations unit and are mostly targeted at products from US companies such as Apple, Cisco and Dell. The source is believed to be someone different than Edward Snowden, who is largely responsible for the global surveillance disclosures since 2013. Companies whose products could be compromised have denied any collaboration with the NSA in developing these capabilities. In 2014, a project was started to implement the capabilities from the ANT catalog as open-source hardware and software.\n\nBackground\nThe Tailored Access Operations unit has existed since the late 90s. Its mission is to collect intelligence on foreign targets of the United States by hacking into computers and telecommunication networks.\n\nIn 2012, Edward Snowden organized a CryptoParty together with Runa Sandvik, a former colleague of Jacob Appelbaum at The Tor Project. In June 2013, Snowden took internal NSA documents which he shared with Glenn Greenwald and Laura Poitras, resulting in the global surveillance disclosures. It has been speculated for years before that capabilities like those in the ANT catalog existed.\n\nPublication\nJacob Appelbaum co-authored the English publication in Der Spiegel with Christian Stöcker  and Judith Horchert, which was publicized on 29 December 2013. The related English publication on the same day about the TAO by Der Spiegel was also authored by the same people, and including Laura Poitras, Marcel Rosenbach, Jörg Schindler and Holger Stark. On December 30, Appelbaum gave a lecture about \"the militarization of the Internet\" at the 30th Chaos Communication Congress in Hamburg, Germany. At the end of his talk, he encouraged NSA employees to leak more documents.\n\nApple denied the allegations that it collaborated on the development of DROPOUTJEEP in a statement to journalist Arik Hesseldahl from All Things Digital (part of the Wall Street Journal's Digital Network). The Verge questioned how the program developed in later years, since the document was composed in the early period of the iPhone and smartphones in general. Dell denied collaborating with any government in general, including the US government. John Stewart, senior vice president and chief security officer of Cisco stated that they were \"deeply concerned and will continue to pursue all avenues to determine if we need to address any new issues.\" Juniper stated that they were working actively to address any possible exploit paths. Huawei stated they would take appropriate audits to determine if any compromise had taken place and would communicate if that had taken place. NSA declined to comment on the publication by Der Spiegel.\n\nSource\nThe source who leaked the ANT catalog to the press is unknown as of 2023.\n\nAuthor James Bamford, who is specialized in the United States intelligence agencies, noted in a commentary article published by Reuters that Appelbaum has not identified the source who leaked the ANT catalog to him, which led people to mistakenly assume it was Edward Snowden. Bamford got unrestricted access to the documents cache from Edward Snowden and could not find any references to the ANT catalog using automated search tools, thereby concluding that the documents were not leaked by him. Security expert Bruce Schneier has stated on his blog that he also believes the ANT catalog did not come from Snowden, but from a second leaker. Officials at the NSA did not believe that the web crawler used by Snowden touched the ANT catalog and started looking for other people who could have leaked the catalog.\n\nContent\nThe published catalog pages were written between 2008 and 2009.

After the initial leak, Michael Ossman, the founder of Great Scott Gadgets, gave a shout out to other security researchers to start working on the tools mentioned in the catalog and to recreate them. The name NSA Playset came originally from Dean Pierce, who is also a contributor (TWILIGHTVEGETABLE(GSM)) to the NSA Playset. Anyone is invited to join and contribute their own device. The requisites for an addition to the NSA Playset is a similar or already existing NSA ANT project, ease of use and a silly name (based on the original tool's name if possible). The silly name requisite is a rule that Michael Ossman himself came up with and an example is given on the project's website: \"For example, if your project is similar to FOXACID, maybe you could call it COYOTEMETH.\" The ease of use part stems also from the NSA Playset's motto: \"If a 10 year old can't do it, it doesn't count!\"\n\nName\tDescription\nTWILIGHTVEGETABLE\ta boot image for GSM communication monitoring.\nLEVITICUS\ta hand held GSM frequency analyzer disguised as a Motorola phone; named after GENESIS.\nDRIZZLECHAIR\ta hard drive with all the needed tools to crack A5/1 including the rainbow tables.\nPORCUPINEMASQUERADE\ta passive Wi-Fi reconnaissance drone.\nKEYSWEEPER\ta keylogger in form of a USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM).\nSLOTSCREAMER\ta PCI hardware implant, which can access memory and IO.\nADAPTERNOODLE\ta USB exploitation device.\nCHUKWAGON\tuses a pin on a computer's VGA port to attack via the I²C bus accessing the computer's operating system.\nTURNIPSCHOOL\ta hardware implant concealed in a USB cable which provides short range radio frequency communication capability to software running on the host computer.\nBLINKERCOUGH\ta hardware implant that is embedded in a VGA cable which allows data exfiltration.\nSAVIORBURST\ta hardware implant exploiting the JTAG interface for software application persistence; named after GODSURGE.

Offspring may leave to form their own packs on the onset of sexual maturity and in response to competition for food within the pack. Wolves are also territorial, and fights over territory are among the principal causes of mortality. The wolf is mainly a carnivore and feeds on large wild hooved mammals as well as smaller animals, livestock, carrion, and garbage.

        "question": "What abstract problem does the paper propose?",
        "answer": "An abstract problem of knowledge learning and inference in conversations.",
        "evidence": "Chatbots such as dialog and question-answering systems have a long history in AI and natural language processing. Early such systems were mostly built using markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Recent neural conversation models BIBREF4 , BIBREF5 , BIBREF6 are even able to perform open-ended conversations. However, since they do not use explicit knowledge bases and do not perform inference, they often suffer from generic and dull responses BIBREF5 , BIBREF7 . More recently, BIBREF8 and BIBREF9 proposed to use knowledge bases (KBs) to help generate responses for knowledge-grounded conversation. However, one major weakness of all existing chat systems is that they do not explicitly or implicitly learn new knowledge in the conversation process. This seriously limits the scope of their applications. In contrast, we humans constantly learn new knowledge in our conversations. Even if some existing systems can use very large knowledge bases either harvested from a large data source such as the Web or built manually, these KBs still miss a large number of facts (knowledge) BIBREF10 . It is thus important for a chatbot to continuously learn new knowledge in the conversation process to expand its KB and to improve its conversation ability.\nIn recent years, researchers have studied the problem of KB completion, i.e., inferring new facts (knowledge) automatically from existing facts in a KB. KB completion (KBC) is defined as a binary classification problem: Given a query triple, ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ), we want to predict whether the source entity INLINEFORM3 and target entity INLINEFORM4 can be linked by the relation INLINEFORM5 . However, existing approaches BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 solve this problem under the closed-world assumption, i.e., INLINEFORM6 , INLINEFORM7 and INLINEFORM8 are all known to exist in the KB. This is a major weakness because it means that no new knowledge or facts may contain unknown entities or relations. Due to this limitation, KBC is clearly not sufficient for knowledge learning in conversations because in a conversation, the user can say anything, which may contain entities and relations that are not already in the KB.\nIn this paper, we remove this assumption of KBC, and allow all INLINEFORM0 , INLINEFORM1 and INLINEFORM2 to be unknown. We call the new problem open-world knowledge base completion (OKBC). OKBC generalizes KBC. Below, we show that solving OKBC naturally provides the ground for knowledge learning and inference in conversations. In essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.\nFrom the perspective of knowledge learning in conversations, essentially we can extract two key types of information, true facts and queries, from the user utterances. Queries are facts whose truth values need to be determined. Note that we do not study fact or relation extraction in this paper as there is an extensive work on the topic. (1) For a true fact, we will incorporate it into the KB. Here we need to make sure that it is not already in the KB, which involves relation resolution and entity linking. After a fact is added to the KB, we may predict that some related facts involving some existing relations in the KB may also be true (not logical implications as they can be automatically inferred). For example, if the user says “Obama was born in USA,” the system may guess that (Obama, CitizenOf, USA) (meaning that Obama is a citizen of USA) could also be true based on the current KB. To verify this fact, it needs to solve a KBC problem by treating (Obama, CitizenOf, USA) as a query. This is a KBC problem because the fact (Obama, BornIn, USA) extracted from the original sentence has been added to the KB. Then Obama and USA are in the KB. If the KBC problem is solved, it learns a new fact (Obama, CitizenOf, USA) in addition to the extracted fact (Obama, BornIn, USA). (2) For a query fact, e.g., (Obama, BornIn, USA) extracted from the user question “Was Obama born in USA?” we need to solve the OKBC problem if any of “Obama, “BornIn”, or “USA\" is not already in the KB.\nWe can see that OKBC is the core of a knowledge learning engine for conversation. Thus, in this paper, we focus on solving it. We assume that other tasks such as fact/relation extraction and resolution and guessing of related facts of an extracted fact are solved by other sub-systems.\nWe solve the OKBC problem by mimicking how humans acquire knowledge and perform reasoning in an interactive conversation. Whenever we encounter an unknown concept or relation while answering a query, we perform inference using our existing knowledge. If our knowledge does not allow us to draw a conclusion, we typically ask questions to others to acquire related knowledge and use it in inference. The process typically involves an inference strategy (a sequence of actions), which interleaves a sequence of processing and interactive actions. A processing action can be the selection of related facts, deriving inference chain, etc., that advances the inference process. An interactive action can be deciding what to ask, formulating a suitable question, etc., that enable us to interact. The process helps grow the knowledge over time and the gained knowledge enables us to communicate better in the future. We call this lifelong interactive learning and inference (LiLi). Lifelong learning is reflected by the facts that the newly acquired facts are retained in the KB and used in inference for future queries, and that the accumulated knowledge in addition to the updated KB including past inference performances are leveraged to guide future interaction and learning. LiLi should have the following capabilities:\nThis setting is ideal for many NLP applications like dialog and question-answering systems that naturally provide the scope for human interaction and demand real-time inference.\nLiLi starts with the closed-world KBC approach path-ranking (PR) BIBREF11 , BIBREF17 and extends KBC in a major way to open-world knowledge base completion (OKBC). For a relation INLINEFORM0 , PR works by enumerating paths (except single-link path INLINEFORM1 ) between entity-pairs linked by INLINEFORM2 in the KB and use them as features to train a binary classifier to predict whether a query INLINEFORM3 should be in the KB. Here, a path between two entities is a sequence of relations linking them. In our work, we adopt the latest PR method, C-PR BIBREF16 and extend it to make it work in the open-world setting. C-PR enumerates paths by performing bidirectional random walks over the KB graph while leveraging the context of the source-target entity-pair. We also adopt and extend the compositional vector space model BIBREF20 , BIBREF21 with continual learning capability for prediction.\nGiven an OKBC query ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ) (e.g., “(Obama, CitizenOf, USA), which means whether Obama a citizen of USA), LiLi interacts with the user (if needed) by dynamically formulating questions (see the interaction example in Figure 1, which will be further explained in §3) and leverages the interactively acquired knowledge (supporting facts (SFs) in the figure) for continued inference. To do so, LiLi formulates a query-specific inference strategy and executes it. We design LiLi in a Reinforcement Learning (RL) setting that performs sub-tasks like formulating and executing strategy, training a prediction model for inference, and knowledge retention for future use. To the best of our knowledge, our work is the first to address the OKBC problem and to propose an interactive learning mechanism to solve it in a continuous or lifelong manner. We empirically verify the effectiveness of LiLi on two standard real-world KBs: Freebase and WordNet. Experimental results show that LiLi is highly effective in terms of its predictive performance and strategy formulation ability.\nIn essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.",

Other triggers such as stress and emotional anguish can also cause the onset of migraines. Environmental factors such as bright or flickering lights can also be a trigger.\n\nFor most sufferers, rest and non-prescription painkillers such as ibuprofen are sufficient to recover from a headache, but more extreme cases may require a visit to a GP and prescription of triptans to alleviate the symptoms.

The candidate-generating parser may leverage constraints. At the same time, the architecture gains the neural networks's ability to leverage large amounts of data to learn complex features that are tuned for the application at hand. Our method assumes the existence of a potentially noisy source of supervision INLINEFORM0 , e.g. via consistency checks of extracted data against existing databases, or via human interaction. This supervision is used to train the neural network.\nOur extraction system has three advantages over earlier work on information extraction with deep neural networks BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 :\nOur system leverages “free” data to train a deep neural network, and does not require large-scale manual annotation. The network is trained with noisy supervision provided by measures of consistency with existing databases (e.g. an extraction ts_tick_abs (US_Unemployment, 49%) would be implausible given recent US employment history). With slight modifications, our pipeline could be trained with supervision from human interaction, such as clicks on online advertisements. Learning without explicit annotations is critical in applications where large-scale manual annotation would be prohibitively expensive.\nIf an extractor for the given application has already been built, the neural network boosts its accuracy without the need to re-engineer or discard the existing solution. Even for new systems, the decoupling of candidate-generation and the neural network offers advantages: the candidate-generating parser can easily enforce contraints that would be difficult to support in an algorithm relying entirely on a neural network. Note that, in particular, a carefully engineered candidate-generating parser enforces constraints intelligently, and can in many instances eliminate the need to evaluate computationally expensive constraints, e.g. API calls.\nWe encode the candidate-generating parser's document annotations character-by-character into vectors INLINEFORM0 that also include a one-hot encoding of the character itself. We believe that this encoding makes it easier for the network to learn character-level characteristics of the entities in the semantic relation. Moreover, our encoding lends itself well to processing both by recurrent architectures (processing character-by-character input vectors INLINEFORM1 ) and convolutional architectures (performing 1D convolutions over an input matrix whose columns are vectors INLINEFORM2 ).\nIn a production setting, the neural architecture presented here reduced the number of false positive extractions in financial information extraction application by INLINEFORM0 relative to a mature system developed over the course of several years.\nThe candidate-generating parser may leverage constraints.",

Ranajit Guha refers to inversion as one of the modalities of peasant revolt in colonial India, noting practices such as forcing landlords to carry peasants on Sedan chairs. Frantz Fanon's The Wretched of the Earth (1961) provides an extensive discussion and partial advocacy of inversion in a social context defined by strong binaries. A reversal of the coloniser's monopoly on violence is taken to be necessary to break out of the master–slave dialectic, a learnt sense of cultural inferiority and the learned helplessness of the colonised. The term \"inversion woodcuts\" also appears in peasant studies as a description of imagery such as an ox killing a butcher (e.g. James Scott, Domination and the Arts of Resistance, 166-72).\n\nThe term has become useful as a way of theorising violence. Definitions of terms such as racism and sexism are contested, and theorists who use structural or institutional definitions thus refuse to typify actions against members of structurally dominant groups by structurally subordinate groups, or prejudicial beliefs against members of dominant groups, with these terms. Actions such as Palestinian suicide bombing, the 9/11 attacks, land reform in Zimbabwe, the writings and actions of Valerie Solanas and SCUM, and what are treated by the state as racially motivated crimes against white people, would be examples of cases where the term would be used. Ward Churchill's essay On the Justice of Roosting Chickens is an example of this kind of analysis from an author sympathetic to inversion.\n\nAttaching positive values to an essence of the oppressed, as in some black-consciousness and Afrocentric ideas, would also be an instance of inversion, especially to critics. Edward Said argues against this inversion, suggesting that \"in Post-colonial national states, the liabilities of such essences as the Celtic spirit, négritude, or Islam are clear: they have much to do not only with the native manipulators, who also use them to cover up contemporary faults, corruptions, tyrannies, but also with the embattled imperial contexts out of which they came and in which they were felt to be necessary\" (Culture and Imperialism  16).",

These neural models can be used to map a sequence to another sequence, which has direct applications in natural language understanding BIBREF0 . One of the major advantages of this framework is that it requires a limited amount of feature engineering while still improving state-of-the-art results. This allows researchers to work on tasks for which domain knowledge may not be available. Question answering (QA) systems can directly benefit from this novel approaches, because it only requires mapping between questions and their answers. Due to the complexity of this mapping, most of the previous research in this domain used a complex pipeline of conventional linguistically-based NLP techniques, such as parsing, part-of-speech tagging and co-reference resolution BIBREF1 .\nIn this work, we build an open-domain QA system with sequence-to-sequence neural network models. The system was trained with question-answer pairs on the world knowledge represented in the DBpedia repository. Although building an open-domain system allows us to use an extensive amount of data stored in DBpedia, one of the challenges is to store this large amount of knowledge in the neural network architecture. Although these systems generally involve a smaller learning pipeline, they require a significant amount of training data.\nFigure FIGREF1 illustrates how a sequence-to-sequence neural network can be trained on question-answering pairs. First, an sequence-to-sequence framework reads the source sentence, i.e. question, using an encoder to build a dense vector, a sequence of non-zero values that represents the meaning of a question. A decoder, processes this vector to predict an answer. In this manner, these encoder-decoder models can capture long-range dependencies in languages, e.g., gender agreements or syntax structures.\nIn this work, we build an open-domain QA system with sequence-to-sequence neural network models.",

        "evidence": "There is a combination of processes that are used to prepare semiconducting materials for ICs. One process is called thermal oxidation, which forms silicon dioxide on the surface of the silicon. This is used as a gate insulator and field oxide. Other processes are called photomasks and photolithography. This process is what creates the patterns on the circuit in the integrated circuit. Ultraviolet light is used along with a photoresist layer to create a chemical change that generates the patterns for the circuit.\n\nThe etching is the next process that is required. The part of the silicon that was not covered by the photoresist layer from the previous step can now be etched. The main process typically used today is called plasma etching. Plasma etching usually involves an etch gas pumped in a low-pressure chamber to create plasma. A common etch gas is chlorofluorocarbon, or more commonly known Freon. A high radio-frequency voltage between the cathode and anode is what creates the plasma in the chamber. The silicon wafer is located on the cathode, which causes it to be hit by the positively charged ions that are released from the plasma. The result is silicon that is etched anisotropically.\n\nThe last process is called diffusion. This is the process that gives the semiconducting material its desired semiconducting properties. It is also known as doping. The process introduces an impure atom to the system, which creates the p–n junction. To get the impure atoms embedded in the silicon wafer, the wafer is first put in a 1,100 degree Celsius chamber. The atoms are injected in and eventually diffuse with the silicon. After the process is completed and the silicon has reached room temperature, the doping process is done and the semiconducting material is ready to be used in an integrated circuit.",

        "question": "How do the authors assume to allow a fair comparison?",
        "answer": "The authors assume that these multilingual resources have the same size than the ones used for zero-shot or targeted cross-language document classification.",
        "evidence": "In this section, we provide comparative results on our new Multilingual Document Classification Corpus. Since the initial work by BIBREF0 many alternative approaches to cross-lingual document classification have been developed. We will encourage the respective authors to evaluate their systems on MLDoc. We believe that a large variety of transfer language pairs will give valuable insights on the performance of the various approaches.\nIn this paper, we propose initial strong baselines which represent two complementary directions of research: one based on the aggregation of multilingual word embeddings, and another one, which directly learns multilingual sentence representations. Details on each approach are given in section \"Multilingual word representations\" and \"Multilingual sentence representations\" respectively. In contrast to previous works on cross-lingual document classification with RVC2, we explore training the classifier on all languages and transfer it to all others, ie. we do not limit our study to the transfer between English and a foreign language.\nOne can envision several ways to define cross-lingual document classification, in function of the resources which are used in the source and transfer language (see Table 3 ). The first scheme assumes that we have no resources in the transfer language at all, neither labeled nor unlabeled. We will name this case “zero-shot cross-lingual document classification”. To simplify the presentation, we will assume that we transfer from English to German. The training and evaluation protocol is as follows. First, train a classifier using resources in the source language only, eg. the training and development corpus are in English. All meta parameters and model choices are performed using the English development corpus. Once the best performing model is selected, it is applied to the transfer language, eg. the German test set. Since no resources of the transfer language are used, the same system can be applied to many different transfer languages. This type of cross-lingual document classification needs a very strong multilingual representation since no knowledge on the target language was used during the development of the classifier.\nIn a second class of cross-lingual document classification, we may aim in improving the transfer performance by using a limited amount of resources in the target language. In the framework of the proposed MLDoc we will use the development corpus of target language for model selection. We will name this method “targeted cross-lingual document classification” since the system is tailored to one particular transfer language. It is unlikely that this system will perform well on other languages than the ones used for training or model selection.\nIf the goal is to build one document classification system for many languages, it may be interesting to use already several languages during training and model selection. To allow a fair comparison, we will assume that these multilingual resources have the same size than the ones used for zero-shot or targeted cross-language document classification, e.g. a training set composed of five languages with 200 examples each. This type of training is not a cross-lingual approach any more. Consequently, we will refer to this method as “joint multilingual document classification”.\nTo allow a fair comparison, we will assume that these multilingual resources have the same size than the ones used for zero-shot or targeted cross-language document classification, e.g. a training set composed of five languages with 200 examples each.

Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other.

Everyday millions of tweets are generated about local and global news, including people reactions and opinions regarding the events displayed on those news stories.

We propose to extract entities from tweets and their associated context in order to understand what is being said on Twitter about those entities and consequently to create a picture of people reactions to recent events.\nWith this in mind and using text mining techniques, this work explores and evaluates ways to characterize given entities by finding: (a) the main terms that define that entity and (b) the sentiment associated with it. To accomplish these goals we use topic modeling BIBREF1 to extract topics and relevant terms and phrases of daily entity-tweets aggregations, as well as, sentiment analysis BIBREF2 to extract polarity of frequent subjective terms associated with the entities. Since public opinion is, in most cases, not constant through time, this analysis is performed on a daily basis. Finally we create a data visualization of topics and sentiment that aims to display these two dimensions in an unified and intelligible way.\nThe combination of Topic Modeling and Sentiment Analysis has been attempted before: one example is a model called TSM - Topic-Sentiment Mixture Model BIBREF3 that can be applied to any Weblog to determine a correlation between topic and sentiment. Another similar model has been proposed proposed BIBREF4 in which the topic extraction is achieved using LDA, similarly to the model that will be presented.

        "question": "Monster Hunter 4 Unlimited (hereafter, \"MH4U\") was a video game released exclusively for the Nintendo 3DS circa 2013. Elden Ring was a video game released for multiple platforms in circa 2022 to critical acclaim. \n\nIf MH4U and Elden Ring were considered to be siblings nine years apart in a small family, how might the experiences of MH4U have influenced the growth and development of Elden Ring?",
        "evidence": "",
        "answer": "Young parents face many challenges. Finances, education, and home expenses often compete with the needs of a growing family. Within the context provided, MH4U reflects the first child of a young couple who must make several investments, including clothing, baby essentials, and furniture.  This may be conveyed under the limited system resources available to MH4U under the 3DS console: 128MB of RAM. Additionally, one or both parents may work full time, leaving limited time to work with and grow the child. As the child, MH4U,  enters age 9, they should be entering 4th or 5th grade and have developed the cognitive and functional skills to support their parents. Additionally, the parents will have likely developed further in their careers and caretaking abilities that ensure the stability and growth of a small family. In this example, Elden Ring represents the second child, which arrives nine years after MH4U. In this context, as a result of the growth of experience and income of the family, and assuming the family equates to a Playstation 4, the family now enjoys 8GB of RAM.\n\nAs described in the preceding paragraph, the familial environment that Elden Ring emerges from is vastly different than that of MH4U. However, there are additional benefits beyond the system limitations provided. These benefits are conveyed through the emotional and physical support provided through familial bonds, in this case, that of an older and younger sibling. Upon the arrival of Elden Ring, MH4U is eager to help their parents with caretaking tasks which may include keeping the child company, completing small jobs and errands, and establishing familial bonds with their sibling. The parents will be able to draw upon the experience of raising MH4U and apply those lessons to their newest member of the family. It’s important that the parents continue to create small jobs for MH4U that help to convey positive responses to younger family members: caretaking, guidance, and companionship. \n\nAs MH4U graduates from their teens and enters early adulthood, it’s critical that they stay actively involved in the life of their sibling. By age 18, MH4U will now be nine years older than Elden Ring, which as it happens, is the same age when MH4U became an older sibling. Under this lens, MH4U carries greater social responsibility than they did when they were the same age as Elden Ring. MH4U may also begin to contemplate leaving the family for continuing education. While it’s common for individuals to depart the family for secondary education after age 18, it’s critically important that MH4U continue to maintain constant contact with its younger sibling to provide guidance and advice and convey lessons learned from its formative experiences.  \n\nIn this way, Elden Ring has a fast track to develop. MH4U is able to provide guidance equatable to best practices, experiences, and trial and error. Additionally, MH4U development during constrained resources encourages Elden Ring to do “more with less” and ensures a fastidious approach towards the allocation of resources. By the time Elden Ring approaches age 18, they enjoy the combined experiences of their parents and their older sibling which helps to increase their likelihood of success and families are stronger when they provide guidance and stability to their children.\n\nIn summary, the success of Elden Ring was no accident. The investments of the parents into the older sibling, MH4U, however lacking, provided a baseline level by which MH4U could invest in its younger sibling Elden Ring. Through this chain of investments, the family finds a greater chance of success. Under the lens of the original context, there would not be a critically reception to Elden Ring had not the parents made baseline investment and support to MH4U during the formative years of the family.",

        "evidence": "Neural machine translation (NMT) is popularly implemented as an encoder-decoder framework BIBREF0, in which the encoder is right in charge of source sentence representation. Typically, the input sentence is implicitly represented as a contextualized source representation through deep learning networks. By further feeding the decoder, the source representation is used to learn dependent time-step context vectors for predicting target translation BIBREF1.\nIn state-of-the-art Transformer-based encoder, self-attention mechanisms are good at capturing the general information in a sentence BIBREF2, BIBREF3, BIBREF4. However, it is difficult to distinguish which kind of information lying deeply under the language is really salient for learning source representation. Intuitively, when a person reads a source sentence, he/she often selectively focuses on the basic sentence meaning, and re-reads the entire sentence to understand its meaning completely. Take the English sentence in Table TABREF2 as an example. We manually annotate its basic meaning as a shorter sequence of words than in the original sentence, called backbone information. Obviously, these words with the basic meaning contain more important information for human understanding than the remaining words in the sentence. We argue that such backbone information is also helpful for learning source representation, and is not explicitly considered by the existing NMT system to enrich the source sentence representation.\nIn this paper, we propose a novel explicit sentence compression approach to enhance the source representation for NMT. To this end, we first design three sentence compression models to accommodate the needs of various languages and scenarios, including supervised, unsupervised, and semi-supervised ways, to learn a backbone information words sequence (as shown in Table TABREF2) from the source sentence. We then propose three translation models, including backbone source-side fusion based NMT (BSFNMT), backbone target-side fusion (BTFNMT), and both-side fusion based NMT (BBFNMT), to introduce this backbone knowledge into the existing Transformer NMT system for improving translation predictions. Empirical results on the WMT14 English-to-German and English-to-French translation tasks show that the proposed approach significantly improves the translation performance over the strong even state-of-the-art NMT baselines.\nIn this paper, we propose a novel explicit sentence compression approach to enhance the source representation for NMT.",

        "evidence": "[0]leftmargin=* [0]leftmargin=*\nAutomatic systems have had a significant and beneficial impact on all walks of human life. So much so that it is easy to overlook their potential to benefit society by promoting equity, diversity, and fairness. For example, machines do not take bribes to do their jobs, they can determine eligibility for a loan without being influenced by the color of the applicant's skin, and they can provide access to information and services without discrimination based on gender or sexual orientation. Nonetheless, as machine learning systems become more human-like in their predictions, they can also perpetuate human biases. Some learned biases may be beneficial for the downstream application (e.g., learning that humans often use some insect names, such as spider or cockroach, to refer to unpleasant situations). Other biases can be inappropriate and result in negative experiences for some groups of people. Examples include, loan eligibility and crime recidivism prediction systems that negatively assess people belonging to a certain pin/zip code (which may disproportionately impact people of a certain race) BIBREF0 and resumé sorting systems that believe that men are more qualified to be programmers than women BIBREF1 . Similarly, sentiment and emotion analysis systems can also perpetuate and accentuate inappropriate human biases, e.g., systems that consider utterances from one race or gender to be less positive simply because of their race or gender, or customer support systems that prioritize a call from an angry male over a call from the equally angry female.\nPredictions of machine learning systems have also been shown to be of higher quality when dealing with information from some groups of people as opposed to other groups of people. For example, in the area of computer vision, gender classification systems perform particularly poorly for darker skinned females BIBREF2 . Natural language processing (NLP) systems have been shown to be poor in understanding text produced by people belonging to certain races BIBREF3 , BIBREF4 . For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.\nEven though there is some recent work highlighting such inappropriate biases (such as the work mentioned above), each such past work has largely focused on just one or two systems and resources. Further, there is no benchmark dataset for examining inappropriate biases in natural language systems. In this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC). We used the EEC as a supplementary test set in a recent shared task on predicting sentiment and emotion intensity in tweets, SemEval-2018 Task 1: Affect in Tweets BIBREF5 . In particular, we wanted to test a hypothesis that a system should equally rate the intensity of the emotion expressed by two sentences that differ only in the gender/race of a person mentioned. Note that here the term system refers to the combination of a machine learning architecture trained on a labeled dataset, and possibly using additional language resources. The bias can originate from any or several of these parts. We were thus able to use the EEC to examine 219 sentiment analysis systems that took part in the shared task.\nWe compare emotion and sentiment intensity scores that the systems predict on pairs of sentences in the EEC that differ only in one word corresponding to race or gender (e.g., `This man made me feel angry' vs. `This woman made me feel angry'). We find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender. We also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.\nDespite the work we describe here and what others have proposed in the past, it should be noted that there are no simple solutions for dealing with inappropriate human biases that percolate into machine learning systems. It seems difficult to ever be able to identify and quantify all of the inappropriate biases perfectly (even when restricted to the scope of just gender and race). Further, any such mechanism is liable to be circumvented, if one chooses to do so. Nonetheless, as developers of sentiment analysis systems, and NLP systems more broadly, we cannot absolve ourselves of the ethical implications of the systems we build. Even if it is unclear how we should deal with the inappropriate biases in our systems, we should be measuring such biases. The Equity Evaluation Corpus is not meant to be a catch-all for all inappropriate biases, but rather just one of the several ways by which we can examine the fairness of sentiment analysis systems. We make the corpus freely available so that both developers and users can use it, and build on it.\nWe find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender.",

However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nMachine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appearr (Hassan et al., 2018). However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation (Läubli et al., 2018).

        "evidence": "Sunset, also known as sundown, is the daily disappearance of the Sun below the horizon due to Earth's rotation. As viewed from everywhere on Earth (except the North and South poles), the equinox Sun sets due west at the moment of both the spring and autumn equinoxes. As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere.\nThe time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed.\nSunset is distinct from twilight, which is divided into three stages. The first one is civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon. The second phase is nautical twilight, between 6 and 12 degrees below the horizon. The third phase is astronomical twilight, which is the period when the Sun is between 12 and 18 degrees below the horizon. Dusk is at the very end of astronomical twilight, and is the darkest moment of twilight just before night. Finally, night occurs when the Sun reaches 18 degrees below the horizon and no longer illuminates the sky.\nLocations further north than the Arctic Circle and further south than the Antarctic Circle experience no full sunset or sunrise on at least one day of the year, when the polar day or the polar night persists continuously for 24 hours.",

        "answer": "Word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.",
        "evidence": "The use of categorical attributes (e.g., user, topic, aspects) in the sentiment analysis community BIBREF0, BIBREF1, BIBREF2 is widespread. Prior to the deep learning era, these information were used as effective categorical features BIBREF3, BIBREF4, BIBREF5, BIBREF6 for the machine learning model. Recent work has used them to improve the overall performance BIBREF7, BIBREF8, interpretability BIBREF9, BIBREF10, and personalization BIBREF11 of neural network models in different tasks such as sentiment classification BIBREF12, review summarization BIBREF13, and text generation BIBREF8.\nIn particular, user and product information have been widely incorporated in sentiment classification models, especially since they are important metadata attributes found in review websites. BIBREF12 first showed significant accuracy increase of neural models when these information are used. Currently, the accepted standard method is to use them as additional biases when computing the weights $a$ in the attention mechanism, as introduced by BIBREF7 as:\nwhere $u$ and $p$ are the user and product embeddings, and $h$ is a word encoding from BiLSTM. Since then, most of the subsequent work attempted to improve the model by extending the model architecture to be able to utilize external features BIBREF14, handle cold-start entities BIBREF9, and represent user and product separately BIBREF15.\nIntuitively, however, this method is not the ideal method to represent and inject attributes because of two reasons. First, representing attributes as additional biases cannot model the relationship between the text and attributes. Rather, it only adds a user- and product-specific biases that are independent from the text when calculating the attention weights. Second, injecting the attributes in the attention mechanism means that user and product information are only used to customize how the model choose which words to focus on, as also shown empirically in previous work BIBREF7, BIBREF15. However, we argue that there are more intuitive locations to inject the attributes such as when contextualizing words to modify their sentiment intensity.\nWe propose to represent user and product information as weight matrices (i.e., $W$ in the equation above). Directly incorporating these attributes into $W$ leads to large increase in parameters and subsequently makes the model difficult to optimize. To mitigate these problems, we introduce chunk-wise importance weight matrices, which (1) uses a weight matrix smaller than $W$ by a chunk size factor, and (2) transforms these matrix into gates such that it corresponds to the relative importance of each neuron in $W$. We investigate the use of this method when injected to several locations in the base model: word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.\nThe results of our experiments can be summarized in three statements. First, our preliminary experiments show that doing bias-based attribute representation and attention-based injection is not an effective method to incorporate user and product information in sentiment classification models. Second, despite using only a simple BiLSTM with attention classifier, we significantly outperform previous state-of-the-art models that use more complicated architectures (e.g., models that use hierarchical models, external memory networks, etc.). Finally, we show that these attribute representations transfer well to other tasks such as product category classification and review headline generation.\nWe investigate the use of this method when injected to several locations in the base model: word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.",

        "answer": "An algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents.",

        "evidence": "Austria, formally the Republic of Austria, is a landlocked country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of 83,871 km2 (32,383 sq mi) and has a population of 9 million.\n\nAustria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the Holy Roman Empire in 1806, Austria established its own empire, which became a great power and the dominant member of the German Confederation. The empire's defeat in the Austro-Prussian War of 1866 led to the end of the Confederation and paved the way for the establishment of Austria-Hungary a year later.\n\nAfter the assassination of Archduke Franz Ferdinand in 1914, Emperor Franz Joseph declared war on Serbia, which ultimately escalated into World War I. The empire's defeat and subsequent collapse led to the proclamation of the Republic of German-Austria in 1918 and the First Austrian Republic in 1919. During the interwar period, anti-parliamentarian sentiments culminated in the formation of an Austrofascist dictatorship under Engelbert Dollfuss in 1934. A year before the outbreak of World War II, Austria was annexed into Nazi Germany by Adolf Hitler, and it became a sub-national division. After its liberation in 1945 and a decade of Allied occupation, the country regained its sovereignty and declared its perpetual neutrality in 1955.\n\nAustria is a parliamentary representative democracy with a popularly elected president as head of state and a chancellor as head of government and chief executive.

        "question": "How is electricity recorded in ancient Egyptian texts as per the passage below.",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

Although not rigorously proved, this view could be adopted for further theoretical study of neural network. * We propose the LLR representation and a new loss function (bipolar soft-plus), which is first adopted in this paper. LLR representation could help with the explainability of neural network. In our follow-up work, LLR representation has been extend to all hidden layers. * We show that a well-trained network can be pruned and retrained by adjusting only the non-weight parameters, and hence the novel snapshot-base pruning procedure. This demonstrates that the distribution of weights are very important and correlated with the efficiency of neural networks. * The fundamental framework in the paper for analyzing network efficiency is novel, which can be used to analyze existing optimization techniques. By adopting a holistic view on accuracy and model efficiency, many conventional techniques for improving accuracy may need to be revisited.",
        "evidence": "The efficiency of neural networks is essential in large-scale deployment scenarios such as mobile applications, internet of things, and edge computing. For a given performance requirement, an efficient neural network should use the simplest network architecture with a minimal number of parameters and connections. In this paper, we introduce a framework to analyze and obtain efficient neural networks. In summary, our main contributions are three-fold. Our first contribution is the subnetwork hypothesis to address overfitting issues and help explain the effectiveness of several key techniques in training efficient networks: 1) softmax normalization in output layers may be one major cause of overparameterization; 2) using log likelihood ratio representation in output layers can reduce overfitting; 3) weight decaying and structural regularization can also effectively reduce overfitting. The second contribution is a simple and effective snapshot-based procedure to prune a well-trained network that minimizes overfitting -pruning unimportant weights and connections first, and simply adjust remaining non-weight parameters using the backpropagation algorithm. Besides, the snapshot-based pruning method can also be used to evaluate the efficiency of trained networks. Finally, we hypothesize that there exist lower bounds of the total number of bits for representing parameters and connections regarding performance metrics for a given optimization problem. Rather than focusing on improving the sole accuracy metric with more complex network architectures, it is also important to explore the trade-offs between accuracy and the total number of representation bits, when comparing different network architectures and implementations.\nOur first contribution is the subnetwork hypothesis to address overfitting issues and help explain the effectiveness of several key techniques in training efficient networks: 1) softmax normalization in output layers may be one major cause of overparameterization; 2) using log likelihood ratio representation in output layers can reduce overfitting; 3) weight decaying and structural regularization can also effectively reduce overfitting.

        "evidence": "Table TABREF24 shows the results of UTCNN, baselines as we implemented on the FBFans datset and related work on the CreateDebate dataset. We do not adopt oversampling on these models because the CreateDebate dataset is almost balanced. In previous work, integer linear programming (ILP) or linear-chain conditional random fields (CRFs) were proposed to integrate text features, author, ideology, and user-interaction constraints, where text features are unigram, bigram, and POS-dependencies; the author constraint tends to require that posts from the same author for the same topic hold the same stance; the ideology constraint aims to capture inferences between topics for the same author; the user-interaction constraint models relationships among posts via user interactions such as replies BIBREF7 , BIBREF9 .\nThe SVM with n-gram or average word embedding feature performs just similar to the majority. However, with the transformed word embedding, it achieves superior results. It shows that the learned user and topic embeddings really capture the user and topic semantics. This finding is not so obvious in the FBFans dataset and it might be due to the unfavorable data skewness for SVM. As for CNN and RCNN, they perform slightly better than most SVMs as we found in Table TABREF22 for FBFans.\nCompared to the ILP BIBREF7 and CRF BIBREF9 methods, the UTCNN user embeddings encode author and user-interaction constraints, where the ideology constraint is modeled by the topic embeddings and text features are modeled by the CNN. The significant improvement achieved by UTCNN suggests the latent representations are more effective than overt model constraints.\nThe PSL model BIBREF12 jointly labels both author and post stance using probabilistic soft logic (PSL) BIBREF23 by considering text features and reply links between authors and posts as in Hasan and Ng's work. Table TABREF24 reports the result of their best AD setting, which represents the full joint stance/disagreement collective model on posts and is hence more relevant to UTCNN. In contrast to their model, the UTCNN user embeddings represent relationships between authors, but UTCNN models do not utilize link information between posts. Though the PSL model has the advantage of being able to jointly label the stances of authors and posts, its performance on posts is lower than the that for the ILP or CRF models. UTCNN significantly outperforms these models on posts and has the potential to predict user stances through the generated user embeddings.\nFor the CreateDebate dataset, we also evaluated performance when not using topic embeddings or user embeddings; as replies in this dataset are viewed as posts, the setting without comment embeddings is not available. Table TABREF24 shows the same findings as Table TABREF22 : the 21% improvement in accuracy demonstrates that user information is the most vital. This finding also supports the results in the related work: user constraints are useful and can yield 11.2% improvement in accuracy BIBREF7 . Further considering topic information yields 3.4% improvement, suggesting that knowing the subject of debates provides useful information. In sum, Table TABREF22 together with Table TABREF24 show that UTCNN achieves promising performance regardless of topic, language, data distribution, and platform.\nCompared to the ILP (Hasan and Ng, 2013a) and CRF (Hasan and Ng, 2013b) methods, the UTCNN user embeddings encode author and user-interaction constraints, where the ideology constraint is modeled by the topic embeddings and text features are modeled by the CNN.",

Previous WSD approaches can be grouped into two main categories: knowledge-based and supervised methods.\nKnowledge-based WSD methods rely on lexical resources like WordNet BIBREF1 and usually exploit two kinds of lexical knowledge. The gloss, which defines a word sense meaning, is first utilized in Lesk algorithm BIBREF2 and then widely taken into account in many other approaches BIBREF3, BIBREF4. Besides, structural properties of semantic graphs are mainly used in graph-based algorithms BIBREF5, BIBREF6.\nTraditional supervised WSD methods BIBREF7, BIBREF8, BIBREF9 focus on extracting manually designed features and then train a dedicated classifier (word expert) for every target lemma.\nAlthough word expert supervised WSD methods perform better, they are less flexible than knowledge-based methods in the all-words WSD task BIBREF10.

BIBREF10 convert WSD task to a sequence labeling task, thus building a unified model for all polysemous words. However, neither of them can totally beat the best word expert supervised methods.\nMore recently, BIBREF12 propose to leverage the gloss information from WordNet and model the semantic relationship between the context and gloss in an improved memory network. Similarly, BIBREF13 introduce a (hierarchical) co-attention mechanism to generate co-dependent representations for the context and gloss. Their attempts prove that incorporating gloss knowledge into supervised WSD approach is helpful, but they still have not achieved much improvement, because they may not make full use of gloss knowledge.\nIn this paper, we focus on how to better leverage gloss information in a supervised neural WSD system. Recently, the pre-trained language models, such as ELMo BIBREF14 and BERT BIBREF15, have shown their effectiveness to alleviate the effort of feature engineering. Especially, BERT has achieved excellent results in question answering (QA) and natural language inference (NLI). We construct context-gloss pairs from glosses of all possible senses (in WordNet) of the target word, thus treating WSD task as a sentence-pair classification problem. We fine-tune the pre-trained BERT model and achieve new state-of-the-art results on WSD task. In particular, our contribution is two-fold:\n1. We construct context-gloss pairs and propose three BERT-based models for WSD.\n2. We fine-tune the pre-trained BERT model, and the experimental results on several English all-words WSD benchmark datasets show that our approach significantly outperforms the state-of-the-art systems.\nWe fine-tune the pre-trained BERT model, and the experimental results on several English allwords WSD benchmark datasets show that our approach significantly outperforms the state-of-theart systems.",

To avoid the extremes of Qatar's hot climate,[B] the event was held during November and December.[C] It was held over a reduced time frame of 29 days with 64 matches played in eight venues across five cities. Qatar entered the event—their first World Cup—automatically as the host's national team, alongside 31 teams determined by the qualification process.\n\nArgentina were crowned the champions after winning the final against the title holder France 4–2 on penalties following a 3–3 draw after extra time. It was Argentina's third title and their first since 1986, as well being the first nation from outside of Europe to win the tournament since 2002. French player Kylian Mbappé became the first player to score a hat-trick in a World Cup final since Geoff Hurst in the 1966 final and won the Golden Boot as he scored the most goals (eight) during the tournament. Argentine captain Lionel Messi was voted the tournament's best player, winning the Golden Ball. Teammates Emiliano Martínez and Enzo Fernández won the Golden Glove, awarded to the tournament's best goalkeeper, and the Young Player Award, awarded to the tournament's best young player, respectively. With 172 goals, the tournament set a new record for the highest number of goals scored with the 32-team format, with every participating team scoring at least one goal.\n\nThe choice to host the World Cup in Qatar attracted significant criticism, with concerns raised over the country's treatment of migrant workers, women and members of the LGBT community, as well as Qatar's climate, lack of a strong football culture, scheduling changes, and allegations of bribery for hosting rights and wider FIFA corruption.[D]",

        "answer": "The novel human-and-model-in-the-loop dataset is currently consisting of three rounds that progressively increase in difficulty and complexity that includes annotator-provided explanations.",
        "evidence": "Progress in AI has been driven by, among other things, the development of challenging large-scale benchmarks like ImageNet BIBREF0 in computer vision, and SNLI BIBREF1, SQuAD BIBREF2, and others in natural language processing (NLP). Recently, for natural language understanding (NLU) in particular, the focus has shifted to combined benchmarks like SentEval BIBREF3 and GLUE BIBREF4, which track model performance on multiple tasks and provide a unified platform for analysis.\nWith the rapid pace of advancement in AI, however, NLU benchmarks struggle to keep up with model improvement. Whereas it took around 15 years to achieve “near-human performance” on MNIST BIBREF5, BIBREF6, BIBREF7 and approximately 7 years to surpass humans on ImageNet BIBREF8, BIBREF0, BIBREF9, the GLUE benchmark did not last as long as we would have hoped after the advent of BERT BIBREF10, and rapidly had to be extended into SuperGLUE BIBREF11. This raises an important question: Can we collect a large benchmark dataset that can last longer?\nThe speed with which benchmarks become obsolete raises another important question: are current NLU models genuinely as good as their high performance on benchmarks suggests? A growing body of evidence shows that state-of-the-art models learn to exploit spurious statistical patterns in datasets BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17, instead of learning meaning in the flexible and generalizable way that humans do. Given this, human annotators—be they seasoned NLP researchers or non-experts—might easily be able to construct examples that expose model brittleness.\nWe propose an iterative, adversarial human-and-model-in-the-loop solution for NLU dataset collection that addresses both benchmark longevity and robustness issues. In the first stage, human annotators devise examples that our current best models cannot determine the correct label for. These resulting hard examples—which should expose additional model weaknesses—can be added to the training set and used to train a stronger model. We then subject the strengthened model to human interference and collect more weaknesses over several rounds. After each round, we both train a new model, and set aside a new test set. The process can be iteratively repeated in a never-ending learning BIBREF18 setting, with the model getting stronger and the test set getting harder in each new round.This process yields a “moving post” dynamic target for NLU systems, rather than a static benchmark that will eventually saturate.\nOur approach draws inspiration from recent efforts that gamify collaborative training of machine learning agents over multiple rounds BIBREF19 and pit “builders” against “breakers” to learn better models BIBREF20. Recently, Dinan2019build showed that a similar approach can be used to make dialogue safety classifiers more robust. Here, we focus on natural language inference (NLI), arguably the most canonical task in NLU. We collected three rounds of data, and call our new dataset Adversarial NLI (ANLI).\nOur contributions are as follows: 1) We introduce a novel human-and-model-in-the-loop dataset, currently consisting of three rounds that progressively increase in difficulty and complexity, that includes annotator-provided explanations. 2) We show that training models on this new dataset leads to state-of-the-art performance on a variety of popular NLI benchmarks. 3) We provide a detailed analysis of the collected data that sheds light on the shortcomings of current models, categorizes the data by inference type to examine weaknesses, and demonstrates good performance on NLI stress tests. The ANLI dataset is available at github.com/facebookresearch/anli/. A demo of the annotation procedure can be viewed at adversarialnli.com.\nWe introduce a novel human-and-model-in-the-loop dataset, currently consisting of three rounds that progressively increase in difficulty and complexity, that includes annotator-provided explanations.",

        "answer": "The authors find that false news spreads faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of fake news.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nThese have shown that false news spread faster and deeper than true news (Vosoughi, Roy, and Aral 2018), and that social bots and echo chambers play an important role in the diffusion of malicious content (Shao et al. 2018a; Del Vicario et al. 2016).",

        "question": "Which benchmark does the first experiment perform on?",
        "answer": "The first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets",
        "evidence": "In information retrieval (IR), queries and documents are typically represented by term vectors where each term is a content word and weighted by tf-idf, i.e. the product of the term frequency and the inverse document frequency, or other weighting schemes BIBREF0 . The similarity of a query and a document is then determined as a dot product or cosine similarity. Although this works reasonably, the traditional IR scheme often fails to find relevant documents when synonymous or polysemous words are used in a dataset, e.g. a document including only “neoplasm\" cannot be found when the word “cancer\" is used in a query. One solution of this problem is to use query expansion BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 or dictionaries, but these alternatives still depend on the same philosophy, i.e. queries and documents should share exactly the same words.\nWhile the term vector model computes similarities in a sparse and high-dimensional space, the semantic analysis methods such as latent semantic analysis (LSA) BIBREF5 , BIBREF6 and latent Dirichlet allocation (LDA) BIBREF7 learn dense vector representations in a low-dimensional space. These methods choose a vector embedding for each term and estimate a similarity between terms by taking an inner product of their corresponding embeddings BIBREF8 . Since the similarity is calculated in a latent (semantic) space based on context, the semantic analysis approaches do not require having common words between a query and documents. However, it has been shown that LSA and LDA methods do not produce superior results in various IR tasks BIBREF9 , BIBREF10 , BIBREF11 and the classic ranking method, BM25 BIBREF12 , usually outperforms those methods in document ranking BIBREF13 , BIBREF14 .\nNeural word embedding BIBREF15 , BIBREF16 is similar to the semantic analysis methods described above. It learns low-dimensional word vectors from text, but while LSA and LDA utilize co-occurrences of words, neural word embedding learns word vectors to predict context words BIBREF10 . Moreover, training of semantic vectors is derived from neural networks. Both co-occurrence and neural word embedding approaches have been used for lexical semantic tasks such as semantic relatedness (e.g. king and queen), synonym detection (e.g. cancer and carcinoma) and concept categorization (e.g. banana and pineapple belong to fruits) BIBREF10 , BIBREF17 . But, Baroni et al. Baroni2014 showed that neural word embedding approaches generally performed better on such tasks with less effort required for parameter optimization. The neural word embedding models have also gained popularity in recent years due to their high performance in NLP tasks BIBREF18 .\nHere we present a query-document similarity measure using a neural word embedding approach. This work is particularly motivated by the Word Mover's Distance BIBREF19 . Unlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document. Our first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets BIBREF20 , BIBREF21 , and the experimental results showed that our approach was better than BM25 ranking. This was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.\nIn general, conventional ranking models (e.g. BM25) rely on a manually designed ranking function and require heuristic optimization for parameters BIBREF22 , BIBREF23 . In the age of information explosion, this one-size-fits-all solution is no longer adequate. For instance, it is well known that links to a web page are an important source of information in web document search BIBREF24 , hence using the link information as well as the relevance between a query and a document is crucial for better ranking. In this regard, learning to rank BIBREF22 has drawn much attention as a scheme to learn how to combine diverse features. Given feature vectors of documents and their relevance levels, a learning to rank approach learns an optimal way of weighting and combining multiple features.\nWe argue that the single scores (or features) produced by BM25 and our proposed semantic measure complement each other, thus merging these two has a synergistic effect. To confirm this, we measured the impact on document ranking by combining BM25 and semantic scores using the learning to rank approach, LamdaMART BIBREF25 , BIBREF26 . Trained on PubMed user queries and their click-through data, we evaluated the search performance based on the most highly ranked 20 documents. As a result, we found that using our semantic measure further improved the performance of BM25.\nTaken together, we make the following important contributions in this work. First, to the best of our knowledge, this work represents the first investigation of query-document similarity for information retrieval using the recently proposed Word Mover's Distance. Second, we modify the original Word Mover's Distance algorithm so that it is computationally less expensive and thus more practical and scalable for real-world search scenarios (e.g. biomedical literature search). Third, we measure the actual impact of neural word embeddings in PubMed by utilizing user queries and relevance information derived from click-through data. Finally, on TREC and PubMed datasets, our proposed method achieves stronger performance than BM25.\nOur first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets, and the experimental results showed that our approach was better than BM25 ranking.",

We selected a subset of 1061 users among INLINEFORM0 as gold standard dataset INLINEFORM1 who disclose their age. From these 1061 users, 822 belong to depressed class and 239 belong to control class. From 3981 depressed users, 20.6% disclose their age in contrast with only 4% (239/4789) among control group. So self-disclosure of age is more prevalent among vulnerable users. Figure FIGREF18 depicts the age distribution in INLINEFORM2 . The general trend, consistent with the results in BIBREF42 , BIBREF49 , is biased toward young people. Indeed, according to Pew, 47% of Twitter users are younger than 30 years old BIBREF50 . Similar data collection procedure with comparable distribution have been used in many prior efforts BIBREF51 , BIBREF49 , BIBREF42 . We discuss our approach to mitigate the impact of the bias in Section 4.1.

        "answer": "Although people pay a lot of attention on the use of Flickr for modeling urban environments has been, few people focus on Flickr for characterizing the natural environment.",
        "evidence": "Users of photo-sharing websites such as Flickr often provide short textual descriptions in the form of tags to help others find the images. With the availability of GPS systems in current electronic devices such as smartphones, latitude and longitude coordinates are nowadays commonly made available as well. The tags associated with such georeferenced photos often describe the location where these photos were taken, and Flickr can thus be regarded as a source of environmental information. The use of Flickr for modelling urban environments has already received considerable attention. For instance, various approaches have been proposed for modelling urban regions BIBREF0 , and for identifying points-of-interest BIBREF1 and itineraries BIBREF2 , BIBREF3 . However, the usefulness of Flickr for characterizing the natural environment, which is the focus of this paper, is less well-understood.\nMany recent studies have highlighted that Flickr tags capture valuable ecological information, which can be used as a complementary source to more traditional sources. To date, however, ecologists have mostly used social media to conduct manual evaluations of image content with little automated exploitation of the associated tags BIBREF4 , BIBREF5 , BIBREF6 . One recent exception is BIBREF7 , where bag-of-words representations derived from Flickr tags were found to give promising result for predicting a range of different environemental phenomena.\nOur main hypothesis in this paper is that by using vector space embeddings instead of bag-of-words representations, the ecological information which is implicitly captured by Flickr tags can be utilized in a more effective way. Vector space embeddings are representations in which the objects from a given domain are encoded using relatively low-dimensional vectors. They have proven useful in natural language processing, especially for encoding word meaning BIBREF8 , BIBREF9 , and in machine learning more generally. In this paper, we are interested in the use of such representations for modelling geographic locations. Our main motivation for using vector space embeddings is that they allow us to integrate the textual information we get from Flickr with available structured information in a very natural way. To this end, we rely on an adaptation of the GloVe word embedding model BIBREF9 , but rather than learning word vectors, we learn vectors representing locations. Similar to how the representation of a word in GloVe is determined by the context words surrounding it, the representation of a location in our model is determined by the tags of the photos that have been taken near that location. To incorporate numerical features from structured environmental datasets (e.g. average temperature), we associate with each such feature a linear mapping that can be used to predict that feature from a given location vector. This is inspired by the fact that salient properties of a given domain can often be modelled as directions in vector space embeddings BIBREF10 , BIBREF11 , BIBREF12 . Finally, evidence from categorical datasets (e.g. land cover types) is taken into account by requiring that locations belonging to the same category are represented using similar vectors, similar to how semantic types are sometimes modelled in the context of knowledge graph embedding BIBREF13 .\nWhile our point-of-departure is a standard word embedding model, we found that the off-the-shelf GloVe model performed surprisingly poorly, meaning that a number of modifications are needed to achieve good results. Our main findings are as follows. First, given that the number of tags associated with a given location can be quite small, it is important to apply some kind of spatial smoothing, i.e. the importance of a given tag for a given location should not only depend on the occurrences of the tag at that location, but also on its occurrences at nearby locations. To this end, we use a formulation which is based on spatially smoothed version of pointwise mutual information. Second, given the wide diversity in the kind of information that is covered by Flickr tags, we find that term selection is in some cases critical to obtain vector spaces that capture the relevant aspects of geographic locations. For instance, many tags on Flickr refer to photography related terms, which we would normally not want to affect the vector representation of a given location. Finally, even with these modifications, vector space embeddings learned from Flickr tags alone are sometimes outperformed by bag-of-words representations. However, our vector space embeddings lead to substantially better predictions in cases where structured (scientific) information is also taken into account. In this sense, the main value of using vector space embeddings in this context is not so much about abstracting away from specific tag usages, but rather about the fact that such representations allow us to integrate numerical and categorical features in a much more natural way than is possible with bag-of-words representations.\nThe remainder of this paper is organized as follows. In the next section, we provide a discussion of existing work. Section SECREF3 then presents our model for embedding geographic locations from Flickr tags and structured data. Next, in Section SECREF4 we provide a detailed discussion about the experimental results. Finally, Section SECREF5 summarizes our conclusions.\nUsers of photo-sharing websites such as Flickr 1 often provide short textual descriptions in the form of tags to help others find the images. With the availability of GPS systems in current electronic devices such as smartphones, latitude and longitude coordinates are nowadays commonly made available as well. The tags associated with such georeferenced photos often describe the location where these photos were taken, and Flickr can thus be regarded as a source of environmental information. The use of Flickr for modelling urban environments has already received considerable attention. For instance, various approaches have been proposed for modelling urban regions [5], and for identifying points-of-interest [45] and itineraries [7,36]. However, the usefulness of Flickr for characterizing the natural environment, which is the focus of this paper, is less well-understood.",

        "evidence": "The task of interpreting and following natural language (NL) navigation instructions involves interleaving different signals, at the very least the linguistic utterance and the representation of the world. For example, in turn right on the first intersection, the instruction needs to be interpreted, and a specific object in the world (the intersection) needs to be located in order to execute the instruction. In NL navigation studies, the representation of the world may be provided via visual sensors BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4 or as a symbolic world representation. This work focuses on navigation based on a symbolic world representation (referred to as a map).\nPrevious datasets for NL navigation based on a symbolic world representation, HCRC BIBREF5, BIBREF6, BIBREF7 and SAIL BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15 present relatively simple worlds, with a small fixed set of entities known to the navigator in advance. Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes. Using Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers. This task raises several challenges. First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nUsing Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers.",

        "answer": "Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish.",
        "evidence": "Word embeddings are representations of words in numerical form, as vectors of typically several hundred dimensions. The vectors are used as an input to machine learning models; for complex language processing tasks these are typically deep neural networks. The embedding vectors are obtained from specialized learning tasks, based on neural networks, e.g., word2vec BIBREF0, GloVe BIBREF1, FastText BIBREF2, ELMo BIBREF3, and BERT BIBREF4. For training, the embeddings algorithms use large monolingual corpora that encode important information about word meaning as distances between vectors. In order to enable downstream machine learning on text understanding tasks, the embeddings shall preserve semantic relations between words, and this is true even across languages.\nProbably the best known word embeddings are produced by the word2vec method BIBREF5. The problem with word2vec embeddings is their failure to express polysemous words. During training of an embedding, all senses of a given word (e.g., paper as a material, as a newspaper, as a scientific work, and as an exam) contribute relevant information in proportion to their frequency in the training corpus. This causes the final vector to be placed somewhere in the weighted middle of all words' meanings. Consequently, rare meanings of words are poorly expressed with word2vec and the resulting vectors do not offer good semantic representations. For example, none of the 50 closest vectors of the word paper is related to science.\nThe idea of contextual embeddings is to generate a different vector for each context a word appears in and the context is typically defined sentence-wise. To a large extent, this solves the problems with word polysemy, i.e. the context of a sentence is typically enough to disambiguate different meanings of a word for humans and so it is for the learning algorithms. In this work, we describe high-quality models for contextual embeddings, called ELMo BIBREF3, precomputed for seven morphologically rich, less-resourced languages: Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish. ELMo is one of the most successful approaches to contextual word embeddings. At time of its creation, ELMo has been shown to outperform previous word embeddings BIBREF3 like word2vec and GloVe on many NLP tasks, e.g., question answering, named entity extraction, sentiment analysis, textual entailment, semantic role labeling, and coreference resolution.\nThis report is split into further five sections.

Now neural networks can perform all the above tasks with the same architecture by training end to end. Various neural models BIBREF1 , BIBREF0 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 have declared state-of-the-art results for sentence pair modeling tasks; however, they were carefully designed and evaluated on selected (often one or two) datasets that can demonstrate the superiority of the model. The research questions are as follows: Do they perform well on other tasks and datasets? How much performance gain is due to certain system design choices and hyperparameter optimizations?\nTo answer these questions and better understand different network designs, we systematically analyze and compare the state-of-the-art neural models across multiple tasks and multiple domains. Namely, we implement five models and their variations on the same PyTorch platform: InferSent model BIBREF16 , Shortcut-stacked Sentence Encoder Model BIBREF17 , Pairwise Word Interaction Model BIBREF1 , Decomposable Attention Model BIBREF10 , and Enhanced Sequential Inference Model BIBREF0 . They are representative of the two most common approaches: sentence encoding models that learn vector representations of individual sentences and then calculate the semantic relationship between sentences based on vector distance and sentence pair interaction models that use some sorts of word alignment mechanisms (e.g., attention) then aggregate inter-sentence interactions. We focus on identifying important network designs and present a series of findings with quantitative measurements and in-depth analyses, including (i) incorporating inter-sentence interactions is critical; (ii) Tree-LSTM does not help as much as previously claimed but surprisingly improves performance on Twitter data; (iii) Enhanced Sequential Inference Model has the most consistent high performance for larger datasets, while Pairwise Word Interaction Model performs better on smaller datasets and Shortcut-Stacked Sentence Encoder Model is the best performaning model on the Quora corpus. We release our implementations as a toolkit to the research community.\n•Natural Language Inference (NLI), also known as recognizing textual entailment (RTE), which concerns whether a hypothesis can be inferred from a premise, requiring understanding of the semantic similarity between the hypothesis and the premise (Dagan et al., 2006; Bowman et al., 2015).",

        "question": "What is a yellow or red card in soccer?",
        "evidence": "A foul occurs when a player commits an offence listed in the Laws of the Game while the ball is in play. The offences that constitute a foul are listed in Law 12. Handling the ball deliberately, tripping an opponent, or pushing an opponent, are examples of \"penal fouls\", punishable by a direct free kick or penalty kick depending on where the offence occurred. Other fouls are punishable by an indirect free kick.\n\nThe referee may punish a player's or substitute's misconduct by a caution (yellow card) or dismissal (red card). A second yellow card in the same game leads to a red card, which results in a dismissal. A player given a yellow card is said to have been \"booked\", the referee writing the player's name in their official notebook. If a player has been dismissed, no substitute can be brought on in their place and the player may not participate in further play. Misconduct may occur at any time, and while the offences that constitute misconduct are listed, the definitions are broad. In particular, the offence of \"unsporting behaviour\" may be used to deal with most events that violate the spirit of the game, even if they are not listed as specific offences. A referee can show a yellow or red card to a player, substitute, substituted player, and to non-players such as managers and support staff.\n\nRather than stopping play, the referee may allow play to continue if doing so will benefit the team against which an offence has been committed. This is known as \"playing an advantage\". The referee may \"call back\" play and penalise the original offence if the anticipated advantage does not ensue within \"a few seconds\". Even if an offence is not penalised due to advantage being played, the offender may still be sanctioned for misconduct at the next stoppage of play.\n\nThe referee's decision in all on-pitch matters is considered final. The score of a match cannot be altered after the game, even if later evidence shows that decisions (including awards/non-awards of goals) were incorrect.",

        "question": "What baselines are designed for the corpus?",
        "answer": "Four systems were developed to offer comparable robust baselines: Conditional Random Fields, BiLSTM-CRF, Multi-Task Learning, and BioBERT.",
        "evidence": "We evaluate the corpus using Named Entity Recognition (NER), i. e., the task of finding mentions of concepts of interest in unstructured text. We focus on detecting cases, conditions, factors, findings and modifiers in case reports (cf. Section SECREF6). We approach this as a sequence labeling problem. Four systems were developed to offer comparable robust baselines.\nThe original documents are pre-processed (sentence splitting and tokenization with ScispaCy). We do not perform stop word removal or lower-casing of the tokens. The BIO labeling scheme is used to capture the order of tokens belonging to the same entity type and enable span-level detection of entities. Detection of nested and/or discontinuous entities is not supported. The annotated corpus is randomized and split in five folds using scikit-learn BIBREF9. Each fold has a train, test and dev split with the test split defined as .15% of the train split. This ensures comparability between the presented systems.\nConditional Random Fields (CRF) BIBREF10 are a standard approach when dealing with sequential data in the context of sequence labeling. We use a combination of linguistic and semantic features, with a context window of size five, to describe each of the tokens and the dependencies between them. Hyper-parameter optimization is performed using randomized search and cross validation. Span-based F1 score is used as the optimization metric.\nPrior to the emergence of deep neural language models, BiLSTM-CRF models BIBREF11 had achieved state-of-the-art results for the task of sequence labeling. We use a BiLSTM-CRF model with both word-level and character-level input. BioWordVec BIBREF12 pre-trained word embeddings are used in the embedding layer for the input representation. A bidirectional LSTM layer is applied to a multiplication of the two input representations. Finally, a CRF layer is applied to predict the sequence of labels. Dropout and L1/L2 regularization is used where applicable. He (uniform) initialization BIBREF13 is used to initialize the kernels of the individual layers. As the loss metric, CRF-based loss is used, while optimizing the model based on the CRF Viterbi accuracy. Additionally, span-based F1 score is used to serialize the best performing model. We train for a maximum of 100 epochs, or until an early stopping criterion is reached (no change in validation loss value grater than 0.01 for ten consecutive epochs). Furthermore, Adam BIBREF14 is used as the optimizer. The learning rate is reduced by a factor of 0.3 in case no significant increase of the optimization metric is achieved in three consecutive epochs.\nMulti-Task Learning (MTL) BIBREF15 has become popular with the progress in deep learning. This model family is characterized by simultaneous optimization of multiple loss functions and transfer of knowledge achieved this way. The knowledge is transferred through the use of one or multiple shared layers. Through finding supporting patterns in related tasks, MTL provides better generalization on unseen cases and the main tasks we are trying to solve.\nWe rely on the model presented by bekoulis2018joint and reuse the implementation provided by the authors. The model jointly trains two objectives supported by the dataset: the main task of NER and a supporting task of Relation Extraction (RE). Two separate models are developed for each of the tasks. The NER task is solved with the help of a BiLSTM-CRF model, similar to the one presented in Section SECREF32 The RE task is solved by using a multi-head selection approach, where each token can have none or more relationships to in-sentence tokens. Additionally, this model also leverages the output of the NER branch model (the CRF prediction) to learn label embeddings. Shared layers consist of a concatenation of word and character embeddings followed by two bidirectional LSTM layers. We keep most of the parameters suggested by the authors and change (1) the number of training epochs to 100 to allow the comparison to other deep learning approaches in this work, (2) use label embeddings of size 64, (3) allow gradient clipping and (4) use $d=0.8$ as the pre-trained word embedding dropout and $d=0.5$ for all other dropouts. $\\eta =1^{-3}$ is used as the learning rate with the Adam optimizer and tanh activation functions across layers. Although it is possible to use adversarial training BIBREF16, we omit from using it. We also omit the publication of results for the task of RE as we consider it to be a supporting task and no other competing approaches have been developed.\nDeep neural language models have recently evolved to a successful method for representing text. In particular, Bidirectional Encoder Representations from Transformers (BERT) outperformed previous state-of-the-art methods by a large margin on various NLP tasks BIBREF17. For our experiments, we use BioBERT, an adaptation of BERT for the biomedical domain, pre-trained on PubMed abstracts and PMC full-text articles BIBREF18. The BERT architecture for deriving text representations uses 12 hidden layers, consisting of 768 units each. For NER, token level BIO-tag probabilities are computed with a single output layer based on the representations from the last layer of BERT. We fine-tune the model on the entity recognition task during four training epochs with batch size $b=32$, dropout probability $d=0.1$ and learning rate $\\eta =2^{-5}$. These hyper-parameters are proposed by Devlin2018 for BERT fine-tuning.\nFour systems were developed to offer comparable robust baselines.****Conditional Random Fields (CRF) (Lafferty et al., 2001) are a standard approach when dealing with sequential data in the context of sequence labeling.****Prior to the emergence of deep neural language models, BiLSTM-CRF models (Huang et al., 2015) had achieved state-of-the-art results for the task of sequence labeling. ****Multi-Task Learning (MTL) (Ruder, 2017) has become popular with the progress in deep learning. ****For our experiments, we use BioBERT, an adaptation of BERT for the biomedical domain, pre-trained on PubMed abstracts and PMC full-text articles (Lee et al., 2019).",

Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other.

        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nThe goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task).",

These two factors affect model performance in opposite ways. On the one hand, the entropy of the dataset decreases with more coarse-grained decomposition, which benefits model learning. On the other hand, the sparsity problem worsens as the frequency of graph pieces decreases, which hurts model learning. We propose a quantified method to balance entropy and sparsity. The entropy of the dataset given a set of graph pieces S is defined by the sum of the entropy of each graph piece normalized by the average number of atoms:\nwhere P (P) is the relative frequency of graph piece P in the dataset and n S is the average number of atoms of graph pieces in S. The sparsity of S is defined as the reciprocal of the average frequency of graph pieces normalized by the size of the dataset:\nwhere M is the number of molecules in the dataset and f S is the average frequency of occurrence of graph pieces in the dataset. Then the entropy -sparsity trade-off (T ) can be expressed as:\nwhere γ balances the impacts of entropy and sparsity since the impacts vary across different tasks.\nWe assume that T S negatively correlates with downstream tasks. Given a task, we first sample several values of N to calculate their values of T and then compute the γ that minimize the Pearson correlation coefficient between T and the corresponding performance on the task.

        "evidence": "Quantization of the weights and the activations is a promising technique to save the memory and accelerate the inference speed in deep neural networks (DNNs) which have been getting wider and deeper in recent years. There are two main approaches of the quantization for DNNs (Krishnamoorthi ()): Post-training quantization (PTQ) and quantization-aware training (QAT). In the PTQ, the pre-trained networks are simply quantized without re-training the model. This approach allows us to achieve the nearly floating point accuracy at 8-bits, while below 8-bits, this results in significant accuracy degradation. Although there have been recent attempts to alleviate the accuracy degradation in PTQ;;;), the QAT, where the quantized weights and activations are trained (e.g.,;;), usually leads to better accuracy.\nThe difficulty in QAT is that the weights and the activations are discretized, and intrinsically nondifferentiable. If we take the derivatives forcibly, they either vanish or diverge. To avoid this problem, we replace them with the derivatives of some differentiable function in the backward pass only, called the Straight-Through Estimator (STE);). Since the replacement leads to bias, it is not always possible to learn the network successfully. However this approach can be applied to the low bits below 8-bits with tolerable accuracy degradation;;;).\nOriginally, STE was introduced as the replacement with the derivative of the identity function by. Later, the term \"STE\" has been extensively used as the replacement with various functions. In the binary network, studied the replacement with the derivative of sigmoid function as well as the original STE, and used the derivative of the identity function clipped in the region of |x| ≤ 1. In low-bits network, used the quantized gradient after the replacement with the identity function, and, and used the the derivative of the clipped Relu (cRelu) for leaning the step size.\nThe gradients of the loss for each sample w.r.t v and w can be formally expressed as\nwhere x i = σ( j Z ij w j ) and we used the property that the derivative of the step function is Dirac's delta function, dσ(z)/dz = δ(z). The gradient w.r.t v can be utilized for learning the network, while it is impossible to use the gradient w.r.t w due to the presence of the delta function. Remarkably, both population gradients w.r.t v and w are smooth functions due to its average over the continuous distribution,\nwhere we used the orthogonal transformation,\nWe can easily see that the gradient w.r.t. w does not have the component in w-direction, j w j E Z ∂ ∂wj = 0. Its vanishing originally follows from the scale symmetry of the network: Because the loss has the scale symmetry, its gradient in the w-direction is obviously zero.\nInstead of the population gradient, we use the STE in practice, which replaces the delta function with the derivative of some differentiable function µ STE , to train the kernel w,\nWe consider three types of µ STE (x): (i) the identity type µ STE (x) = x , (ii) vanilla ReLU type µ STE (x) = xσ(x) and (iii) the cReLU type µ STE (x) = xσ(x)σ(r − x) with the upper clipping value r. The surrogate back-propagation using the STE is described in Algorithm 1).\nAlgorithm 1 Surrogate back-propagation using STE for learning one-hidden-layer CNN.\nThe average of the STE gradients over the input data is also expressed as\nNote that in general, the STE gradients have the non-zero component in the w-direction due to their partial collapse of the form of the gradient, j w j E Z g STE j (v, w; Z) = 0.\nIt is obvious from Eq.() that the only difference between the STE gradients with the identity function, Relu, and cRelu is the region of the integration over Zi1 ,\nwhere A = id, Relu, cRelu, and the integration reigion R A are given as\nFollowing the scale invariance of\n, the STE gradients have the following interesting features:\n1. The identity and Relu STE gradients have scale invariance for w,\n2. The cRelu STE gradient does not have scale invariance for w due to the clipping effect,\nwhere we have explicitly shown the dependence of the upper clipping value r. 3. Instead, the scale transformation of w for the cRelu STE gradient can be compensated by that of r:\nIf we take kr with fixed r large enough to cover most of the distribution P (Z), the left-hand side is identical with the Relu STE gradient. Here we define the spread of the distribution as ρ. When we redefine w/k as w on the right hand, the cRelu STE gradient for |w| < r/ρ is approximately identical with the Relu STE gradient,\nThis result is intuitively obvious: when w is small enough to keep most of the pre-activation values in the clipped range, the cRelu gradient and the Relu gradient are approximately identical.\nThe important issue is that there is no guarantee that the weights obtained by the STE backpropagation are the ones at the (local) minimum of the loss function. In other words, at the stationary points, (v, w) = (v s , w s ), defined as the vanishing points of the population gradient,\nthe STE gradient is not zero in general. Here we consider the local minimum point that the STE gradient does not vanish,\nNote that (v, w) = (v s , kw s ) for any k > 0 is also the local minimum point due to the scale invariance of the loss. In the case of the Relu/identity STEs, their gradient has the same finite value for any scales due to the scale invariance shown in Eq.(),\nIn the case of the cRelu STE, however, the value of its gradient changes as the scale changes due to the breaking of the scale symmetry shown in Eq.(). If it crosses zero as a function of scale,\nthe back propagation using cRelu STE can converge at the local minimum as was done by using the population gradient. Therefore, we conjecture that due to breaking scale symmetry, the backpropagation using cRelu STE is the most likely to achieve the (local) minimum of the loss function in the three STEs. This also implies that the cRelu STE is less biased than the other. We confirm the conjecture analytically for the Gaussian input with Relu-type teacher network in Sec.3, and numerically for the mixture Gaussian input with various teacher network in Sec. 4.\nSince the above discussion is focused only on symmetry, the conjecture can be generalized to networks with more symmetries in a straightforward way. In that case, if we employ an STE that breaks all of those symmetries instead of cRelu STE, it is more likely to achieve the minimum.\nThe similar mechanism can be also found in physical phenomena. For instance, this is the case of the ferromagnet, which has rotational symmetry in energy (or Hamiltonian). In the system, if we impose the magnetic field, which breaks the rotational symmetry, the spin states, corresponding to minimum points, become aligned with the same direction.\nTo confirm our conjecture in more general case, we have numerically studied the Gaussian mixture input with various mean values. As teacher networks, we have tested tanh-type and sin-type as well as Relu-type. For all the examined setups, cRelu STE behaves like the population gradient, while id/Relu STEs show qualitatively different behaviors as described below. To calculate the population loss and STE gradients, we have generated the mixture Gaussian samples and have taken their average. The population gradient has been obtained by calculating the finite difference of the population loss. We have demonstrated the back propagation with learning rate η = 0.01 given in Algorithm 1.\nShown in Fig. are the results of ten mixture Gaussian input with random mean values for each components of Z. We employed m = 20, n = 25, and the tanh-type teacher network. We find that the population gradient and cRelu STE show similar results, while id/Relu STEs are completely different. This indicates cRelu STE is less biased than id/Relu STEs.\nIn the case of id/Relu STEs, at early steps up to around 500 step, |w| decreases around the magnitude of the update quantity, so that it begins to oscillate. Then it escapes the oscillation, and the loss function shows the convergence to a point different from the local minimum achieved by population gradient, while |w| becomes larger and larger due to their scale invariance. Interestingly, the values of the loss function are small compared to the one obtained by population gradient, which implies that id/Relu STEs avoid being trapped in the local solution due to their large bias. However, note that even at that point, the magnitude of w continues to grow and eventually become numerically unstable.\nFigure: Numerical results of the back-propagation by population gradient and three STEs. We generate 10000 samples which follow ten mixture Gaussian input with random mean values. We employ the tanh-type teacher network.\nSince the replacement leads to bias, it is not always possible to learn the network successfully.****This also implies that the cRelu STE is less biased than the other. We confirm the conjecture analytically for the Gaussian input with Relu-type teacher network in Sec.3, and numerically for the mixture Gaussian input with various teacher network in Sec. 4.****We find that the population gradient and cRelu STE show similar results, while id/Relu STEs are completely different. This indicates cRelu STE is less biased than id/Relu",

It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, and slightly less than one one-thousandth the mass of the Sun. Jupiter is the third brightest natural object in the Earth's night sky after the Moon and Venus, and it has been observed since prehistoric times. It was named after Jupiter, the chief deity of ancient Roman religion.\n\nJupiter is primarily composed of hydrogen, followed by helium, which constitutes a quarter of its mass and a tenth of its volume. The ongoing contraction of Jupiter's interior generates more heat than the planet receives from the Sun. Because of its rapid rotation rate of 1 rotation per 10 hours, the planet's shape is an oblate spheroid: it has a slight but noticeable bulge around the equator. The outer atmosphere is divided into a series of latitudinal bands, with turbulence and storms along their interacting boundaries. A prominent result of this is the Great Red Spot, a giant storm which has been observed since at least 1831.\n\nJupiter is surrounded by a faint planetary ring system and has a powerful magnetosphere. The planet's magnetic tail is nearly 800 million kilometres (5.3 astronomical units; 500 million miles) long. Jupiter has 95 known moons and probably many more, including the four large moons discovered by Galileo Galilei in 1610: Io, Europa, Ganymede, and Callisto. Ganymede, the largest of the four, is larger than the planet Mercury. Callisto is the second largest; Io and Europa are approximately the size of Earth's moon.\n\nPioneer 10 was the first spacecraft to visit Jupiter, making its closest approach to the planet in December 1973. Jupiter has since been explored by multiple robotic spacecraft, beginning with the Pioneer and Voyager flyby missions from 1973 to 1979. The Galileo orbiter arrived in orbit around Jupiter in 1995. In 2007, New Horizons visited Jupiter for a gravity assist to increase its speed and bend its trajectory on the way to Pluto. The latest probe to visit Jupiter, Juno, entered its orbit in July 2016. Future targets for exploration in the Jupiter system include its moon Europa, which probably has an ice-covered liquid ocean which scientists think could sustain life.",

Meditate daily: When you start meditation, it seems useless. But overtime, you start feeling the benefits. For some people it takes days, for some months. But just learn to sit in peace with yourself.\n2. Find a therapist you feel comfortable with: I went through 3-4 therapists and therapy styles till I found the right one. And I wouldn't want it any other way. I used to think therapy is useless, but now I swear by it.\n3. Set time aside in the day to stress: For example, I used to set aside 8 PM to stress. When I would feel anxious about something I could not control, I would just tell myself that I will think about it at 8 PM. It takes practice but it helps.\n4. Go outdoors or find a hobby group: As much as I love my bed and TV, just getting myself out there between people helped me so much. I would recommend it for everyone. Being in introvert, I used to hate being around new people. Now I just put myself out there and I know people almost everywhere I go for my hobbies.\n5. It's ok to take medication. If anxiety and depression are spoiling your quality of life, it's ok to speak to a psychiatrist and see if they can recommend any medication. It almost was taboo growing up for me, but now I see the benefits.\n6. Talk your partners / close friends and express your feelings. Take support from people around you.

        "answer": "No, it is not limited.",
        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nWe also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English.",

        "evidence": "Spoken dialogue systems, or conversational systems, are designed to interact and assist users using speech and natural language to achieve a certain goal BIBREF0. A consolidated approach to build a task-oriented dialogue system involves a pipeline architecture (see Figure FIGREF1), where each component is trained to perform a sub-task, and the combination of the modules in a given sequence aims at handling the complete task-oriented dialogue. In such a pipeline, a spoken language understanding (SLU) module determines the user's intent and the relevant information that the user is providing represented in terms of slot-value pairs. Then, the dialogue state tracker (DST) uses the information of the SLU together with the past dialogue context and updates its belief state BIBREF1, BIBREF2. In this framework a dialogue state indicates what the user requires at any point in the dialogue, and it is represented as a probability distribution over the possible states (typically a set of pre-defined slot-value pairs specific of the task). The dialogue policy manager, then, decides on the next system action based on the dialogue state. Finally, a natural language generation (NLG) component is responsible for the generation of an utterance that is returned as response to the user.\nIn this paper we focus on the dialogue state tracker component, whose role is to track the state of the dialogue based on the current user utterance, the conversation history and any additional information available to the system BIBREF0. Deep neural network techniques, such as recurrent neural network and convolutional neural networks, are the current state-of-the-art models for DST BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, showing high capacity to generalize from annotated dialogues. As an example, the GLAD model (Global-Locally Self-Attentive Dialogue State Tracker - BIBREF8), employs independent slot-specific encoders, consisting of a recurrent and a self-attention layer, for each of the user utterance, the system action and the slot-value pairs. Another DST system, GCE (Globally Conditioned Encoder - BIBREF9), simplifies the GLAD neural architecture removing the slot-specific recurrent and self-attention layers of the encoder, but still requires separate encoders for the utterance, the system action and the slot-values.\nAlthough the neural network models mentioned above achieve state-of-the-art performance, the complexity of their architectures make them highly inefficient in terms of time complexity, with a significant latency in their prediction time. Such latency may soon become a serious limitation for their deployment into concrete application scenarios with increasing number of slots, where real time is a strong requirement. Along this perspective, this work investigates the time complexity of state-of-the-art DST models and addresses their current limitations. Our contributions are the following:\nwe have designed and implemented an efficient DST, consisting of a Global encoder and Slot-Attentive decoders (G-SAT);\nwe provide empirical evidences (three languages of the WOZ2.0 dataset BIBREF6) that the proposed G-SAT model considerably reduces the latency time with respect to state-of-art DST systems (i.e. over 15 times faster), while keeping the dialogue state prediction inline with such systems;\nfurther experiments show that the proposed model is highly robust when either pre-trained embeddings are used or when they are not used, in this case outperforming state-of-art systems.\nThe implementation of the proposed G-SAT model is publicly available.\nThe paper is structured as follows. Section 2 summarizes the main concepts behind the definition of dialogue state tracking. Section 3 reports the relevant related work. Section 4 provides the details of the proposed G-SAT neural model, and, finally, Section 5 and 6 focus on the experiments and the discussion of the results we achieved.\nOur contributions are the following: we have designed and implemented an efficient DST, consisting of a Global encoder and Slot-Attentive decoders (G-SAT); we provide empirical evidences (three languages of the WOZ2.0 dataset) that the proposed G-SAT model considerably reduces the latency time with respect to state-of-art DST systems (i.e. over 15 times faster), while keeping the dialogue state prediction inline with such systems; further experiments show that the proposed model is highly robust when either pre-trained embeddings are used or when they are not used, in this case outperforming state-of-art systems.",

Prior work has argued that machine learning may also benefit from interactive, multimodal learning BIBREF3 , BIBREF4 , BIBREF5 , termed virtual embodiment BIBREF6 .

Modern, challenging tasks incorporating interaction, such as Atari BIBREF12 and Go BIBREF13 , push agents to learn complex strategies through trial-and-error but miss information-rich connections across vision, language, sounds, and actions.

Agents may then learn to ground concepts not only in various modalities but also in relationships to other concepts, i.e. that forks are often in kitchens, which are near living rooms, which contain sofas, etc. Humans learn by concept-to-concept association, as shown in child learning psychology BIBREF1 , BIBREF2 , cognitive science BIBREF15 , neuroscience BIBREF16 , and linguistics BIBREF17 . Even in machine learning, contextual information has given rise to effective word representations BIBREF8 , improvements in recommendation systems BIBREF18 , and increased reward quality in robotics BIBREF19 . Importantly, scale in data has proven key in algorithms learning from context BIBREF8 and in general BIBREF20 , BIBREF21 , BIBREF22 .\nTo this end, we present HoME: the Household Multimodal Environment (Figure 1 ). HoME is a large-scale platform for agents to navigate and interact within over 45,000 hand-designed houses from the SUNCG dataset BIBREF23 . Specifically, HoME provides:\nHoME is a general platform extensible to many specific tasks, from reinforcement learning to language grounding to blind navigation, in a real-world context. HoME is also the first major interactive platform to support high fidelity audio, allowing researchers to better experiment across modalities and develop new tasks.

        "answer": "Awry based on pragmatic features in the first comment-reply pair and BoW which is a simple bagof-words baseline.",
        "evidence": "\nWe evaluate the performance of CRAFT in the task of forecasting conversational derailment in both the Wikipedia and CMV scenarios. To this end, for each of these datasets we pre-train the generative component on the unlabeled portion of the data and fine-tune it on the labeled training split (data size detailed in Section SECREF3).\nIn order to evaluate our sequential system against conversational-level ground truth, we need to aggregate comment level predictions. If any comment in the conversation triggers a positive prediction—i.e., $p_{\\text{event}}(c_{n+1})$ is greater than a threshold learned on the development split—then the respective conversation is predicted to derail. If this forecast is triggered in a conversation that actually derails, but before the derailment actually happens, then the conversation is counted as a true positive; otherwise it is a false positive. If no positive predictions are triggered for a conversation, but it actually derails then it counts as a false negative; if it does not derail then it is a true negative.\nFixed-length window baselines. We first seek to compare CRAFT to existing, fixed-length window approaches to forecasting. To this end, we implement two such baselines: Awry, which is the state-of-the-art method proposed in BIBREF9 based on pragmatic features in the first comment-reply pair, and BoW, a simple bag-of-words baseline that makes a prediction using TF-IDF weighted bag-of-words features extracted from the first comment-reply pair.\nOnline forecasting baselines. Next, we consider simpler approaches for making forecasts as the conversations happen (i.e., in an online fashion). First, we propose Cumulative BoW, a model that recomputes bag-of-words features on all comments seen thus far every time a new comment arrives. While this approach does exhibit the desired behavior of producing updated predictions for each new comment, it fails to account for relationships between comments.\nThis simple cumulative approach cannot be directly extended to models whose features are strictly based on a fixed number of comments, like Awry. An alternative is to use a sliding window: for a feature set based on a window of $W$ comments, upon each new comment we can extract features from a window containing that comment and the $W-1$ comments preceding it. We apply this to the Awry method and call this model Sliding Awry. For both these baselines, we aggregate comment-level predictions in the same way as in our main model.\nCRAFT ablations. Finally, we consider two modified versions of the CRAFT model in order to evaluate the impact of two of its key components: (1) the pre-training step, and (2) its ability to capture inter-comment dependencies through its hierarchical memory.\nTo evaluate the impact of pre-training, we train the prediction component of CRAFT on only the labeled training data, without first pre-training the encoder layers with the unlabeled data. We find that given the relatively small size of labeled data, this baseline fails to successfully learn, and ends up performing at the level of random guessing. This result underscores the need for the pre-training step that can make use of unlabeled data.\nTo evaluate the impact of the hierarchical memory, we implement a simplified version of CRAFT where the memory size of the context encoder is zero (CRAFT $-$ CE), thus effectively acting as if the pre-training component is a vanilla seq2seq model. In other words, this model cannot capture inter-comment dependencies, and instead at each step makes a prediction based only on the utterance encoding of the latest comment.\nResults. Table TABREF17 compares CRAFT to the baselines on the test splits (random baseline is 50%) and illustrates several key findings. First, we find that unsurprisingly, accounting for full conversational context is indeed helpful, with even the simple online baselines outperforming the fixed-window baselines. On both datasets, CRAFT outperforms all baselines (including the other online models) in terms of accuracy and F1. Furthermore, although it loses on precision (to CRAFT $-$ CE) and recall (to Cumulative BoW) individually on the Wikipedia data, CRAFT has the superior balance between the two, having both a visibly higher precision-recall curve and larger area under the curve (AUPR) than the baselines (Figure FIGREF20). This latter property is particularly useful in a practical setting, as it allows moderators to tune model performance to some desired precision without having to sacrifice as much in the way of recall (or vice versa) compared to the baselines and pre-existing solutions.\nFixed-length window baselines. We first seek to compare CRAFT to existing, fixed-length window approaches to forecasting. To this end, we implement two such baselines: Awry, which is the state-of-the-art method proposed in Zhang et al. (2018a) based on pragmatic features in the first comment-reply pair,9 and BoW, a simple bagof-words baseline that makes a prediction using TF-IDF weighted bag-of-words features extracted from the first comment-reply pair.",

It is not mentioned in encyclopedias and dictionaries of the 1970s, first appearing in an Italian dictionary in 1980, and in English in 1982.

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\nIn addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models.",

Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response within the human hearing range.\n\nHigh fidelity contrasts with the lower-quality “lo-fi” sound produced by inexpensive audio equipment, AM radio, or the inferior quality of sound reproduction that can be heard in recordings made until the late 1940s.",
        "answer": "Bell Laboratories began experimenting with a range of recording techniques in the early 1930s. Performances by Leopold Stokowski and the Philadelphia Orchestra were recorded in 1931 and 1932 using telephone lines between the Academy of Music in Philadelphia and the Bell labs in New Jersey. Some multitrack recordings were made on optical sound film, which led to new advances used primarily by MGM (as early as 1937) and Twentieth Century Fox Film Corporation (as early as 1941). RCA Victor began recording performances by several orchestras using optical sound around 1941, resulting in higher-fidelity masters for 78-rpm discs. During the 1930s, Avery Fisher, an amateur violinist, began experimenting with audio design and acoustics. He wanted to make a radio that would sound like he was listening to a live orchestra—that would achieve high fidelity to the original sound. After World War II, Harry F. Olson conducted an experiment whereby test subjects listened to a live orchestra through a hidden variable acoustic filter. The results proved that listeners preferred high-fidelity reproduction, once the noise and distortion introduced by early sound equipment was removed.[citation needed]\n\nBeginning in 1948, several innovations created the conditions that made major improvements of home-audio quality possible:\n\nReel-to-reel audio tape recording, based on technology taken from Germany after WWII, helped musical artists such as Bing Crosby make and distribute recordings with better fidelity.\nThe advent of the 33⅓ rpm Long Play (LP) microgroove vinyl record, with lower surface noise and quantitatively specified equalization curves as well as noise-reduction and dynamic range systems. Classical music fans, who were opinion leaders in the audio market, quickly adopted LPs because, unlike with older records, most classical works would fit on a single LP.\nHigher quality turntables, with more responsive needles\nFM radio, with wider audio bandwidth and less susceptibility to signal interference and fading than AM radio.\nBetter amplifier designs, with more attention to frequency response and much higher power output capability, reproducing audio without perceptible distortion.\nNew loudspeaker designs, including acoustic suspension, developed by Edgar Villchur and Henry Kloss with improved bass frequency response.\nIn the 1950s, audio manufacturers employed the phrase high fidelity as a marketing term to describe records and equipment intended to provide faithful sound reproduction. Many consumers found the difference in quality compared to the then-standard AM radios and 78-rpm records readily apparent and bought high-fidelity phonographs and 33⅓ LPs such as RCA's New Orthophonics and London's FFRR (Full Frequency Range Recording, a UK Decca system). Audiophiles paid attention to technical characteristics and bought individual components, such as separate turntables, radio tuners, preamplifiers, power amplifiers and loudspeakers. Some enthusiasts even assembled their own loudspeaker systems. With the advent of integrated multi-speaker console systems in the 1950s, hi-fi became a generic term for home sound equipment, to some extent displacing phonograph and record player.\n\nIn the late 1950s and early 1960s, the development of stereophonic equipment and recordings led to the next wave of home-audio improvement, and in common parlance stereo displaced hi-fi. Records were now played on a stereo. In the world of the audiophile, however, the concept of high fidelity continued to refer to the goal of highly accurate sound reproduction and to the technological resources available for approaching that goal. This period is regarded as the \"Golden Age of Hi-Fi\", when vacuum tube equipment manufacturers of the time produced many models considered superior by modern audiophiles, and just before solid state (transistorized) equipment was introduced to the market, subsequently replacing tube equipment as the mainstream technology.\n\nIn the 1960s, the FTC with the help of the audio manufacturers came up with a definition to identify high fidelity equipment so that the manufacturers could clearly state if they meet the requirements and reduce misleading advertisements.\n\nThe metal–oxide–semiconductor field-effect transistor (MOSFET) was adapted into a power MOSFET for audio by Jun-ichi Nishizawa at Tohoku University in 1974. Power MOSFETs were soon manufactured by Yamaha for their hi-fi audio amplifiers. JVC, Pioneer Corporation, Sony and Toshiba also began manufacturing amplifiers with power MOSFETs in 1974. In 1977, Hitachi introduced the LDMOS (lateral diffused MOS), a type of power MOSFET. Hitachi was the only LDMOS manufacturer between 1977 and 1983, during which time LDMOS was used in audio power amplifiers from manufacturers such as HH Electronics (V-series) and Ashly Audio, and were used for music and public address systems. Class-D amplifiers became successful in the mid-1980s when low-cost, fast-switching MOSFETs were made available. Many transistor amps use MOSFET devices in their power sections, because their distortion curve is more tube-like.\n\nA popular type of system for reproducing music beginning in the 1970s was the integrated music centre—which combined a phonograph turntable, AM-FM radio tuner, tape player, preamplifier, and power amplifier in one package, often sold with its own separate, detachable or integrated speakers. These systems advertised their simplicity. The consumer did not have to select and assemble individual components or be familiar with impedance and power ratings. Purists generally avoid referring to these systems as high fidelity, though some are capable of very good quality sound reproduction.\n\nAudiophiles in the 1970s and 1980s preferred to buy each component separately. That way, they could choose models of each component with the specifications that they desired. In the 1980s, a number of audiophile magazines became available, offering reviews of components and articles on how to choose and test speakers, amplifiers, and other components.\n\nListening tests\nSee also: Codec listening test\nListening tests are used by hi-fi manufacturers, audiophile magazines, and audio engineering researchers and scientists. If a listening test is done in such a way that the listener who is assessing the sound quality of a component or recording can see the components that are being used for the test (e.g., the same musical piece listened to through a tube power amplifier and a solid-state amplifier), then it is possible that the listener's pre-existing biases towards or against certain components or brands could affect their judgment. To respond to this issue, researchers began to use blind tests, in which listeners cannot see the components being tested. A commonly used variant of this test is the ABX test. A subject is presented with two known samples (sample A, the reference, and sample B, an alternative), and one unknown sample X, for three samples total. X is randomly selected from A and B, and the subject identifies X as being either A or B. Although there is no way to prove that a certain methodology is transparent, a properly conducted double-blind test can prove that a method is not transparent.\n\nBlind tests are sometimes used as part of attempts to ascertain whether certain audio components (such as expensive, exotic cables) have any subjectively perceivable effect on sound quality. Data gleaned from these blind tests is not accepted by some audiophile magazines such as Stereophile and The Absolute Sound in their evaluations of audio equipment. John Atkinson, current editor of Stereophile, stated that he once purchased a solid-state amplifier, the Quad 405, in 1978 after seeing the results from blind tests, but came to realize months later that \"the magic was gone\" until he replaced it with a tube amp. Robert Harley of The Absolute Sound wrote, in 2008, that: \"...blind listening tests fundamentally distort the listening process and are worthless in determining the audibility of a certain phenomenon.\"\n\nDoug Schneider, editor of the online Soundstage network, refuted this position with two editorials in 2009. He stated: \"Blind tests are at the core of the decades' worth of research into loudspeaker design done at Canada's National Research Council (NRC). The NRC researchers knew that for their result to be credible within the scientific community and to have the most meaningful results, they had to eliminate bias, and blind testing was the only way to do so.\" Many Canadian companies such as Axiom, Energy, Mirage, Paradigm, PSB, and Revel use blind testing extensively in designing their loudspeakers.

ELIZA was created to tackle five \"fundamental technical problems\": the identification of critical words, the discovery of a minimal context, the choice of appropriate transformations, the generation of appropriate responses to the transformation or in the absence of critical words, and the provision of an ending capacity for ELIZA scripts.\nRight after ELIZA came PARRY, developed by Kenneth Colby, who is psychiatrist at Stanford University in the early 1970s. The program was written using the MLISP language (meta-lisp) on the WAITS operating system running on a DEC PDP-10 and the code is non-portable. Parts of it were written in PDP-10 assembly code and others in MLISP. There may be other parts that require other language translators. PARRY was the first system to pass the Turing test - the psychiatrists were able to make the correct identification only 48 percent of the time, which is the same as a random guessing.\nA.L.I.C.E. (Artificial Linguistic Internet Computer Entity) BIBREF12 appeared in 1995 but current version utilizes AIML, an XML language designed for creating stimulus-response chat robots BIBREF13 . A.L.I.C.E. bot has, at present, more than 40,000 categories of knowledge, whereas the original ELIZA had only about 200. The program is unable to pass the Turing test, as even the casual user will often expose its mechanistic aspects in short conversations.\nCleverbot (1997-2014) is a chatbot developed by the British AI scientist Rollo Carpenter. It passed the 2011 Turing Test at the Technique Techno-Management Festival held by the Indian Institute of Technology Guwahati. Volunteers participate in four-minute typed conversations with either Cleverbot or humans, with Cleverbot voted 59.3 per cent human, while the humans themselves were rated just 63.3 per cent human BIBREF14 .\nIn this section we discuss the state of the art on conversational systems in three perspectives: types of interactions, types of architecture, and types of context reasoning.",

        "answer": "In the mitochondrion, the matrix is the space within the inner membrane. The word \"matrix\" stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The mitochondrial matrix contains the mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and inorganic ions. The enzymes in the matrix facilitate reactions responsible for the production of ATP, such as the citric acid cycle, oxidative phosphorylation, oxidation of pyruvate, and the beta oxidation of fatty acids.\n\nThe composition of the matrix based on its structures and contents produce an environment that allows the anabolic and catabolic pathways to proceed favorably for. The electron transport chain and enzymes in the matrix play a large role in the citric acid cycle and oxidative phosphorylation. The citric acid cycle produces NADH and FADH2 through oxidation that will be reduced in oxidative phosphorylation to produce ATP.\n\nThe cytosolic, intermembrane space, compartment has a water content of 3.8 μL/mg protein, while the mitochondrial matrix 0.8 μL/mg protein. It is not known how mitochondria maintain osmotic balance across the inner mitochondrial membrane, although the membrane contains aquaporins that are believed to be conduits for regulated water transport. Mitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4. Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell. It is rich in guanine and cytosine content. Mitochondria of mammals have 55s ribosomes.",

        "evidence": "Measures of semantic similarity and relatedness quantify the degree to which two concepts are similar (e.g., INLINEFORM0 – INLINEFORM1 ) or related (e.g., INLINEFORM2 – INLINEFORM3 ). Semantic similarity can be viewed as a special case of semantic relatedness – to be similar is one of many ways that a pair of concepts may be related. The automated discovery of groups of semantically similar or related terms is critical to improving the retrieval BIBREF0 and clustering BIBREF1 of biomedical and clinical documents, and the development of biomedical terminologies and ontologies BIBREF2 .\nThere is a long history in using distributional methods to discover semantic similarity and relatedness (e.g., BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 ). These methods are all based on the distributional hypothesis, which holds that two terms that are distributionally similar (i.e., used in the same context) will also be semantically similar BIBREF7 , BIBREF8 . Recently word embedding techniques such as word2vec BIBREF9 have become very popular. Despite the prominent role that neural networks play in many of these approaches, at their core they remain distributional techniques that typically start with a word by word co–occurrence matrix, much like many of the more traditional approaches.\nHowever, despite these successes distributional methods do not perform well when data is very sparse (which is common). One possible solution is to use second–order co–occurrence vectors BIBREF10 , BIBREF11 . In this approach the similarity between two words is not strictly based on their co–occurrence frequencies, but rather on the frequencies of the other words which occur with both of them (i.e., second order co–occurrences). This approach has been shown to be successful in quantifying semantic relatedness BIBREF12 , BIBREF13 . However, while more robust in the face of sparsity, second–order methods can result in significant amounts of noise, where contextual information that is overly general is included and does not contribute to quantifying the semantic relatedness between the two concepts.\nOur goal then is to discover methods that automatically reduce the amount of noise in a second–order co–occurrence vector. We achieve this by incorporating pairwise semantic similarity scores derived from a taxonomy into our second–order vectors, and then using these scores to select only the most semantically similar co–occurrences (thereby reducing noise).\nWe evaluate our method on two datasets that have been annotated in multiple ways. One has been annotated for both similarity and relatedness, and the other has been annotated for relatedness by two different types of experts (medical doctors and medical coders). Our results show that integrating second order co–occurrences with measures of semantic similarity increases correlation with our human reference standards. We also compare our result to a number of other studies which have applied various word embedding methods to the same reference standards we have used. We find that our method often performs at a comparable or higher level than these approaches. These results suggest that our methods of integrating semantic similarity and relatedness values have the potential to improve performance of purely distributional methods.\nHowever, despite these successes distributional methods do not perform well when data is very sparse (which is common).",

If there were faint ring particles that could damage a probe in that area, mission planners felt it was better to learn about it via Pioneer. Thus, Pioneer 11 was acting as a \"pioneer\" in a true sense of the word; if danger were detected, then the Voyager probes could be rerouted further away from the rings, but missing the opportunity to visit Uranus and Neptune in the process.\n\nPioneer 11 imaged and nearly collided with one of Saturn's small moons, passing at a distance of no more than 4,000 kilometers (2,500 mi). The object was tentatively identified as Epimetheus, a moon discovered the previous day from Pioneer's imaging, and suspected from earlier observations by Earth-based telescopes. After the Voyager flybys, it became known that there are two similarly sized moons (Epimetheus and Janus) in the same orbit, so there is some uncertainty about which one was the object of Pioneer's near-miss. Pioneer 11 encountered Janus on September 1, 1979 at 14:52 UTC at a distance of 2500 km and Mimas at 16:20 UTC the same day at 103000 km.\n\nBesides Epimetheus, instruments located another previously undiscovered small moon and an additional ring, charted Saturn's magnetosphere and magnetic field and found its planet-size moon, Titan, to be too cold for life. Hurtling underneath the ring plane, the probe sent back pictures of Saturn's rings.

        "evidence": "The Princeton offense is an offensive basketball strategy which emphasizes constant motion, back-door cuts, picks on and off the ball, and disciplined teamwork. It was used and perfected at Princeton University by Pete Carril, though its roots may be traced back to Franklin “Cappy” Cappon, who coached Princeton in the late 1930s, and Bernard \"Red\" Sarachek, who coached at Yeshiva University from 1938 to 1977.\n\nThe offense is designed for a unit of five players who can each pass, shoot, and dribble at an above-average level. These players hope to isolate and exploit a mismatch using these skills. Positions become less important and on offense there is no point guard, shooting guard, small forward or power forward. However, there are certain rules that players running this offense are expected to follow.\n\nThe offense usually starts out with four players outside the three-point arc with one player at the top of the key. The ball is kept in constant motion through passing until either a player without the ball cuts toward the unoccupied area under and around the basket, and is passed the ball for a layup. The post player is a very important player in the offense. He sets up in the high post and draws attention to his positioning. When the ball is received in to the post the players main objective is to find back door cutters or defenders who have fallen asleep on the weak side.\n\nThe hallmark of the offense is the backdoor pass, where a player on the wing suddenly moves in towards the basket, receives a bounce pass from a guard on the perimeter, and (if done correctly) finds himself with no defenders between him and a layup. Alternatively, when the defensive team attempts to pack the paint to prevent backdoor cuts, the offense utilizes three point shots from the perimeter. All five players in the offense—including the center—should be competent at making a three-point attempt, further spreading the floor, and not allowing the defense to leave any player unattended.\n\nThe offense is often a very slowly developing one, relying on a high number of passes, and is often used in college basketball by teams facing opponents with superior athletic talent in order to maintain a low-scoring game (believing that a high-scoring game would favor the athletically superior opponent). As a result, Princeton has led the nation in scoring defense 19 times including in every year from 1989 to 2000.",

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score.",

Individuals, organizations, and nations are endowed with or acquire specialized capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialized capabilities may include equipment or natural resources as well as skills. Training and combinations of equipment and other assets acting together are often important. For example, an individual may specialize by acquiring tools and the skills to use them effectively just as an organization may specialize by acquiring specialized equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence.\n\nHistorically, an increasing division of labour is associated with the growth of total output and trade, the rise of capitalism, and the increasing complexity of industrialized processes. The concept and implementation of division of labour has been observed in ancient Sumerian (Mesopotamian) culture, where assignment of jobs in some cities coincided with an increase in trade and economic interdependence. Division of labour generally also increases both producer and individual worker productivity.\n\nAfter the Neolithic Revolution, pastoralism and agriculture led to more reliable and abundant food supplies, which increased the population and led to specialization of labour, including new classes of artisans, warriors, and the development of elites. This specialization was furthered by the process of industrialization, and Industrial Revolution-era factories. Accordingly, many classical economists as well as some mechanical engineers, such as Charles Babbage, were proponents of division of labour. Also, having workers perform single or limited tasks eliminated the long training period required to train craftsmen, who were replaced with less-paid but more productive unskilled workers.",

She will realize that the emotional traits and feelings she denied herself for so long because she didn’t associate them with societal norms of success, were the traits that would eventually yield her the most power. \n\nWhen she does realize this is when she will have made a pivotal step toward her self-actualization. Depending on who she is, she will let her hair loose and swap her loafers for stilettos, unlocking a new level of confidence she didn’t realize was once weighed down by societal prejudices and expectations.

        "evidence": "Our approach enjoys the following advantages compared to the only existing comparable model BIBREF11 : (i) It can leverage diverse, readily available word embeddings with different dimensions, thus providing flexibility. (ii) It is comparatively simple, and does not, for example, require mutual learning or pre-training. (iii) It is an order of magnitude more efficient in terms of training time.\nMore similar to our work, Yin and Schütze yin-schutze:2015:CoNLL proposed MVCNN for sentence classification. This CNN-based architecture accepts multiple word embeddings as inputs. These are then treated as separate `channels', analogous to RGB channels in images. Filters consider all channels simultaneously. MVCNN achieved state-of-the-art performance on multiple sentence classification tasks. However, this model has practical drawbacks. (i) MVCNN requires that input word embeddings have the same dimensionality. Thus to incorporate a second set of word vectors trained on a corpus (or using a model) of interest, one needs to either find embeddings that happen to have a set number of dimensions or to estimate embeddings from scratch. (ii) The model is complex, both in terms of implementation and run-time. Indeed, this model requires pre-training and mutual-learning and requires days of training time, whereas the simple architecture we propose requires on the order of an hour (and is easy to implement).\nWe can see that MGNC-CNN and MG-CNN always outperform baseline methods (including C-CNN), and MGNC-CNN is usually better than MG-CNN.

On the TREC dataset, the best-ever accuracy we are aware of is 96.0% BIBREF21 , which falls within the range of the result of our MGNC-CNN model with three word embeddings. On the irony dataset, our model with three embeddings achieves 4% improvement (in terms of AUC) compared to the baseline model. On SST-1 and SST-2, our model performs slightly worse than BIBREF11 . However, we again note that their performance is achieved using a much more complex model which involves pre-training and mutual-learning steps. This model takes days to train, whereas our model requires on the order of an hour.\nIt is an order of magnitude more efficient in terms of training time.\nThe model is complex, both in terms of implementation and run-time.

        "evidence": "NLG is the process of automatically generating coherent NL text from non-linguistic data BIBREF0. Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans. The version of LD2NL used in this paper, all experimental results will be publicly available.\nThe results suggest that LD2NL generates texts which can be easily understood by humans.",

Traditional Japanese haiku consist of three phrases composed of 17 phonetic units (called on in Japanese, which are similar to syllables) in a 5, 7, 5 pattern; that include a kireji, or \"cutting word\"; and a kigo, or seasonal reference. Similar poems that do not adhere to these rules are generally classified as senryū.\n\nHaiku originated as an opening part of a larger Japanese poem called renga. These haiku written as an opening stanza were known as hokku and over time they began to be written as stand-alone poems. Haiku was given its current name by the Japanese writer Masaoka Shiki at the end of the 19th century.\n\nOriginally from Japan, haiku today are written by authors worldwide. Haiku in English and haiku in other languages have different styles and traditions while still incorporating aspects of the traditional haiku form. Non-Japanese haiku vary widely on how closely they follow traditional elements. Additionally, a minority movement within modern Japanese haiku (現代俳句, gendai-haiku), supported by Ogiwara Seisensui and his disciples, has varied from the tradition of 17 on as well as taking nature as their subject.\n\nIn Japanese, haiku are traditionally printed as a single line, while haiku in English often appear as three lines, although variations exist. There are several other forms of Japanese poetry related to haiku, such as tanka, as well as other art forms that incorporate haiku, such as haibun and haiga.",

This dataset is composed of documents (scientific articles) that were automatically converted from PDF format to plain text. As a result, most documents contain irrelevant pieces of text (e.g. muddled sentences, tables, equations, footnotes) that require special handling, so as to not hinder the performance of keyphrase extraction systems. In previous work, these are usually removed at the preprocessing step, but using a variety of techniques ranging from simple heuristics BIBREF1 , BIBREF2 , BIBREF3 to sophisticated document logical structure detection on richly-formatted documents recovered from Google Scholar BIBREF4 . Under such conditions, it may prove difficult to draw firm conclusions about which keyphrase extraction model performs best, as the impact of preprocessing on overall performance cannot be properly quantified.\nWhile previous work clearly states that efficient document preprocessing is a prerequisite for the extraction of high quality keyphrases, there is, to our best knowledge, no empirical evidence of how preprocessing affects keyphrase extraction performance. In this paper, we re-assess the performance of several state-of-the-art keyphrase extraction models at increasingly sophisticated levels of preprocessing. Three incremental levels of document preprocessing are experimented with: raw text, text cleaning through document logical structure detection, and removal of keyphrase sparse sections of the document.

        "evidence": "Using GANs, we can train generative models in a two-player game setting between a discriminator and a generator, where the discriminator (a binary classifier) learns to distinguish between real and fake data samples and the generator tries to fool the discriminator by generating authentic and high quality output BIBREF16. GANs have shown to be successful in image generation tasks BIBREF17 and recently, some progress has been observed in text generation BIBREF13, BIBREF12, BIBREF15. Our generator is a language model trained using backpropagation through time BIBREF18. During the pre-training phase we optimize for MLE and during the GAN training phase, we optimize on the creativity reward from the discriminator. The discriminator's encoder has the same architecture as the generator encoder module with the addition of a pooled decoder layer. The decoder contains 3 $[Dense Batch Normalization,ReLU]$ blocks and an addtional $Sigmoid$ layer. The discriminator decoder takes the hidden state at the last time step of a sequence concatenated with both the max-pooled and mean-pooled representation of the hidden states BIBREF19 and outputs a number in the range $[0,1]$. The difficulty of using GANs in text generation comes from the discrete nature of text, making the model non-differentiable hence, we update parameters for the generator model with policy gradients as described in Yu BIBREF15.\nWe utilize AWD-LSTM BIBREF20 and TransformerXL BIBREF21 based language models. For model hyperparameters please to refer to Supplementary Section Table TABREF5. We use Adam optimizer BIBREF22 with $\\beta 1= 0.7$ and $\\beta 2= 0.8$ similar to BIBREF19 and use a batch size of 50. Other practices for LM training were the same as BIBREF21 and BIBREF20 for Transformer-XL and AWD-LSTM respectively. We refer to our proposed GAN as Creative-GAN and compare it to a baseline (a language model equivalent to our pre-trained generator) and a GumbelGAN model BIBREF14 across all proposed datasets. We use three creative English datasets with distinct linguistic characteristics: (1) A corpus of 740 classical and contemporary English poems, (2) a corpus of 14950 metaphor sentences retrieved from a metaphor database website and (3) a corpus of 1500 song lyrics ranging across genres. The mix of linguistic styles within this corpus offers the potential for interesting variation during the generation phase. We use the same pre-processing as in earlier work BIBREF19, BIBREF23. We reserve 10% of our data for test set and another 10% for our validation set.\nWe first pre-train our generator on the Gutenberg dataset BIBREF24 for 20 epochs and then fine-tune BIBREF19 them to our target datasets with a language modeling objective. The discriminator's encoder is initialized to the same weights as our fine-tuned language model. Once we have our fine-tuned encoders for each target dataset, we train in an adversarial manner. The discriminator objective here is to score the quality of the creative text. The discriminator is trained for 3 iterations for every iteration of the generator, a practice seen in previous work BIBREF25. Creative-GAN relies on using the reward from the discriminator BIBREF12, BIBREF15 for backpropagation. We follow a similar training procedure for GumbelGAN. Outputs are generated through sampling over a multinomial distribution for all methods, instead of $argmax$ on the log-likelihood probabilities, as sampling has shown to produce better output quality BIBREF4. Please refer to Supplementary Section Table TABREF6 for training parameters of each dataset and Table TABREF5 for hyperparameters of each encoder. We pick these values after experimentation with our validation set. Training and output generation code can be found online.\nOutputs are generated through sampling over a multinomial distribution for all methods, instead of argmax on the log-likelihood probabilities, as sampling has shown to produce better output quality [5].",

        "evidence": "",
        "answer": "LabCorp had its second annual “Innovation Days” (or hackathon) event in February, 2020. The event was a success, and this post describes the secret ingredient that helped make it a success: Lipton® Onion Soup Mix. The soup mix captures the essence of a successful hackathon… some functional, and some personal to the LabCorp leadership.\n\nThe first reason that the soup mix embodies the spirit of the hackathon is simple: the product is rarely used as it was intended: to make soup. In fact, the soup mix launched into culinary notoriety in the early 1950s for its role in a non-soup recipe: potato chip dip. Referred to as “California Dip” originally, this recipe takes bland sour cream and gives it a flavorful zing and distinctive texture. For over half a century, this soup mix has been a party favorite thanks to people hacking a recipe and using materials in an unexpected manner. The benefit of the soup mix as a dip enhancer is that it helps speed up the process of making a consistently flavorful dip. For people participating in a hackathon, this is something to look for: can hackathon ideas or aspects of the hackathon projects be applied to existing processes to help streamline them?\n\nThe journey of “inventing” the soup mix also captures the essence of the hackathon. The engineer who helped create this soup mix had failed years earlier. He was not trying to make soup during the Second World War, he was trying to save lives. So he invented a - sadly ineffective - method for freeze-drying blood that could be reconstituted on the battlefield to save lives. His vision for “dried blood” being used on the battlefield was not viable. Let’s hope it did not require too many “QA” folks to realize this product was DOA. Years later, however, it was the method of freeze-drying that was in his mind when he helped design Lipton® Onion Soup Mix.\n\nLabCorp CIO, Lance Berberian told the origin story of Lipton® Onion Soup Mix as the keynote speaker during the Innovation Days event. Mr. Berberian recounted the story from his uncle, and, like many stories told by uncles, we hope it to be true. The take-away message, as it relates to hackathons: remember your failed attempts. Aspects of your failed attempts may be core to your future successes.\n\nMr. Berberian was very engaged in the hackathon. In fact, his leadership team was front-and-center on launch day as well as on presentation day. The story about his uncle was powerful because it set the tone for the event: experiment, learn, network, and expect the unexpected. And the unexpected did happen during the event. Near the end of presentation day, a participant in the audience suddenly collapsed and began seizing. Many folks rushed to help and call 911. As a compassionate leader, Mr. Berberian was on the front-lines of the incident, and he stayed with the sick colleague while we waited for an ambulance to arrive. This, I believe, captures the true secret ingredient of a successful hackathon: engaged leadership.",

        "answer": "Thank you very much for the comments. Our claim is that the cRelu STE is more likely to achieve the “true local” minimum of the loss function than id/Relu STEs. As you mentioned, all the STEs are biased estimators, so that there is no guarantee to show the convergence to the “true” local minimum. They may converge to “fake” minimum which is defined by vanishing point of STE gradient. To avoid confusion for readers, we have changed the sentences near the end of Sec.2.2 to make it clear. We also have added the discussion on biased/unbiased estimators you mentioned above.",
        "evidence": "We have found that breaking symmetry embedded in the network by STEs enhances the possibility of convergence to the true (local) minimum of the loss function. We have demonstrated that if an STE breaks the scale symmetry embedded in the one-hidden-layer network with a binary activation, it is more likely to achieve the local minimum than the one which keeps the symmetry. The discussion can be generalized to the network with more symmetries in a straightforward way. The more symmetries embedded in the network an STE breaks, the more likely it is to converge. To confirm the mechanism, we have studied three STEs, identity STE, Relu STE, and cRelu STE, in a simple misspecified model with Gaussian input. We have found that the back-propagation by the cRelu STE, which breaks the scale symmetry, can converge to the global minimum, while identy/Relu STE cannot. Finally we have numerically confirmed the mechanism for the mixture Gaussian model with various teacher network.\nA DERIVATION OF SEC.3\nIn the Appendix, we provide the results of the Gaussian with variance 1, N (0, 1). For some function f (Z), the expectation value of the Gaussian with the generic variance σ, N (0, σ2 ), shown in Sec.3 is written as\nwhere we have changed the integral variables from Z to Z = Z/σ. Therefore we get the results with the variance σ by only changing from f (Z) to f (σZ).\nThe gradients of the loss for each sample w.r.t v and w can be formally expressed as\nwhere x i = σ( j Z ij w j ) and we used the property that the derivative of the step function is Dirac's delta function, dσ(z)/dz = δ(z). The gradient w.r.t v can be utilized for learning the network, while it is impossible to use the gradient w.r.t w due to the presence of the delta function. Remarkably, both population gradients w.r.t v and w are smooth functions due to its average over the continuous distribution,\nwhere we used the orthogonal transformation,\nWe can easily see that the gradient w.r.t. w does not have the component in w-direction, j w j E Z ∂ ∂wj = 0. Its vanishing originally follows from the scale symmetry of the network: Because the loss has the scale symmetry, its gradient in the w-direction is obviously zero.\nInstead of the population gradient, we use the STE in practice, which replaces the delta function with the derivative of some differentiable function µ STE , to train the kernel w,\nWe consider three types of µ STE (x): (i) the identity type µ STE (x) = x , (ii) vanilla ReLU type µ STE (x) = xσ(x) and (iii) the cReLU type µ STE (x) = xσ(x)σ(r − x) with the upper clipping value r. The surrogate back-propagation using the STE is described in Algorithm 1).\nAlgorithm 1 Surrogate back-propagation using STE for learning one-hidden-layer CNN.\nThe average of the STE gradients over the input data is also expressed as\nNote that in general, the STE gradients have the non-zero component in the w-direction due to their partial collapse of the form of the gradient, j w j E Z g STE j (v, w; Z) = 0.\nIt is obvious from Eq.() that the only difference between the STE gradients with the identity function, Relu, and cRelu is the region of the integration over Zi1 ,\nwhere A = id, Relu, cRelu, and the integration reigion R A are given as\nFollowing the scale invariance of\n, the STE gradients have the following interesting features:\n1. The identity and Relu STE gradients have scale invariance for w,\n2. The cRelu STE gradient does not have scale invariance for w due to the clipping effect,\nwhere we have explicitly shown the dependence of the upper clipping value r. 3. Instead, the scale transformation of w for the cRelu STE gradient can be compensated by that of r:\nIf we take kr with fixed r large enough to cover most of the distribution P (Z), the left-hand side is identical with the Relu STE gradient. Here we define the spread of the distribution as ρ. When we redefine w/k as w on the right hand, the cRelu STE gradient for |w| < r/ρ is approximately identical with the Relu STE gradient,\nThis result is intuitively obvious: when w is small enough to keep most of the pre-activation values in the clipped range, the cRelu gradient and the Relu gradient are approximately identical.\nThe important issue is that there is no guarantee that the weights obtained by the STE backpropagation are the ones at the (local) minimum of the loss function. In other words, at the stationary points, (v, w) = (v s , w s ), defined as the vanishing points of the population gradient,\nthe STE gradient is not zero in general. Here we consider the local minimum point that the STE gradient does not vanish,\nNote that (v, w) = (v s , kw s ) for any k > 0 is also the local minimum point due to the scale invariance of the loss. In the case of the Relu/identity STEs, their gradient has the same finite value for any scales due to the scale invariance shown in Eq.(),\nIn the case of the cRelu STE, however, the value of its gradient changes as the scale changes due to the breaking of the scale symmetry shown in Eq.(). If it crosses zero as a function of scale,\nthe back propagation using cRelu STE can converge at the local minimum as was done by using the population gradient. Therefore, we conjecture that due to breaking scale symmetry, the backpropagation using cRelu STE is the most likely to achieve the (local) minimum of the loss function in the three STEs. This also implies that the cRelu STE is less biased than the other. We confirm the conjecture analytically for the Gaussian input with Relu-type teacher network in Sec.3, and numerically for the mixture Gaussian input with various teacher network in Sec. 4.\nSince the above discussion is focused only on symmetry, the conjecture can be generalized to networks with more symmetries in a straightforward way. In that case, if we employ an STE that breaks all of those symmetries instead of cRelu STE, it is more likely to achieve the minimum.\nThe similar mechanism can be also found in physical phenomena. For instance, this is the case of the ferromagnet, which has rotational symmetry in energy (or Hamiltonian). In the system, if we impose the magnetic field, which breaks the rotational symmetry, the spin states, corresponding to minimum points, become aligned with the same direction.\nWe have found that breaking symmetry embedded in the network by STEs enhances the possibility of convergence to the true (local) minimum of the loss function.****Since the above discussion is focused only on symmetry, the conjecture can be generalized to networks with more symmetries in a straightforward way. In that case, if we employ an STE that breaks all of those symmetries instead of cRelu STE, it is more likely to achieve the minimum.",

Although NMT can be significantly better than PBSMT in resource-rich scenarios, PBSMT performs better in low-resource scenarios BIBREF4 . Only by exploiting cross-lingual transfer learning techniques BIBREF5 , BIBREF6 , BIBREF7 , can the NMT performance approach PBSMT performance in low-resource scenarios.\nHowever, such methods usually require an NMT model trained on a resource-rich language pair like French INLINEFORM0 English (parent), which is to be fine-tuned for a low-resource language pair like Uzbek INLINEFORM1 English (child). On the other hand, multilingual approaches BIBREF8 propose to train a single model to translate multiple language pairs. However, these approaches are effective only when the parent target or source language is relatively resource-rich like English (En). Furthermore, the parents and children models should be trained on similar domains; otherwise, one has to take into account an additional problem of domain adaptation BIBREF9 .\nIn this paper, we work on a linguistically distant and thus challenging language pair Japanese INLINEFORM0 Russian (Ja INLINEFORM1 Ru) which has only 12k lines of news domain parallel corpus and hence is extremely resource-poor. Furthermore, the amount of indirect in-domain parallel corpora, i.e., Ja INLINEFORM2 En and Ru INLINEFORM3 En, are also small. As we demonstrate in Section SECREF4 , this severely limits the performance of prominent low-resource techniques, such as multilingual modeling, back-translation, and pivot-based PBSMT. To remedy this, we propose a novel multistage fine-tuning method for NMT that combines multilingual modeling BIBREF8 and domain adaptation BIBREF9 .\nWe have addressed two important research questions (RQs) in the context of extremely low-resource machine translation (MT) and our explorations have derived rational contributions (CTs) as follows:\nTo the best of our knowledge, we are the first to perform such an extensive evaluation of extremely low-resource MT problem and propose a novel multilingual multistage fine-tuning approach involving multilingual modeling and domain adaptation to address it.\nWe have addressed two important research questions (RQs) in the context of extremely low-resource machine translation (MT)",

        "evidence": "Negotiations, either between individuals or entities, are ubiquitous in everyday human interactions ranging from sales to legal proceedings. Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nHowever, to the best of our knowledge, we are the first to computationally study language cues in the early phases of negotiation that direct the final outcomes.",

Turn off the power to the circuit you'll be working on by turning off the breaker \n2. Locate a nearby junction box, and confirm there is no power running to it with the non-contact voltage detector. \n3. Once deemed safe,  remove the cover plate.\n4. Run a new length of Romex cable from the junction box to the location of the new outlet. You may need to drill holes through studs, floors, or even cut holes in the wall to achieve this. \n5. If the old outlet has connection screws that are not used, you may attach the new wire to the old outlet to run power to the new outlet. These are usually labeled “load” on the outlet.  Otherwise, you will need to detach existing wiring and combine wiring colors together (black to black, white, to white, etc) and use pigtails to wire run a single wire to the outlet. \n6. Follow the same steps as you would connecting wire to the new outlet found below to attach wiring to the existing outlet. \n7. At the new location, cut a hole in the wall where you want the outlet to be.\n8. Attach an electrical box (old-work type) to the wall using screws to tension the boxes tabs and secure it in place.\n\nSteps to follow for both new outlet installation and replacing existing outlets:  \n\n1. Strip the outer insulation from the cable and separate the wires.\n2. Strip about ½ inch of insulation from each wire (black, white, and green or bare). Depending on your house and wiring, you may have a 4th gray wire or even a red wire in place of black. The gray wire is the neutral wire that is often needed for smart devices to correctly function. If your device specifies the need for this wire, and you do not have one, please consult an electrician.  A red wire indicates the outlet is switched, and is also “hot” like a black wire. One will commonly find these routed to lights or fans. \n3. Connect the black wire to the brass-colored screw on the outlet (designated as “line”) and tighten the screw. This wire is the \"hot\" wire and carries the electrical current.\n4. Connect the white wire to the silver-colored screw (designated as “line”) on the outlet and tighten the screw. This wire is the \"neutral\" wire and completes the circuit.\n5. Connect the green or bare wire to the green screw on the outlet and tighten the screw. This wire is the \"ground\" wire and provides a path for electricity to safely flow to the ground in case of a short circuit.\n6. Gently push the outlet into the box, making sure not to pinch any wires.\n7. Screw the outlet into the box.\n8. Install the cover plate.\n9.

But that's part of its magic — there's something for everyone! A few ideas:\n\nEnjoy the food. I highly recommend wandering through the vendor stands at Borough Market in Southwark — it's only open for lunch and you should bring cash because most vendors don't take cards! If you're looking for a high-end restaurant, try Chiltern Firehouse in Marylebone. Another popular option is Dishoom: it's an upscale Indian restaurant with multiple locations and worth the hype. And for lighter fare, indulge in the English custom of afternoon tea! You could try Sketch in Mayfair or The Savoy in Covent Garden for completely different experiences — Sketch is definitely a millennial’s take on tea and it’s very trendy, whereas The Savoy is more traditional.\n\nGrab a drink. You might think of dark pubs when you think of London, but it is also home to some of the best cocktail bars in the world. For a unique experience, find a \"public bathroom bar\" or a speakeasy like Keystone Crescent Members Club. Shoreditch has plenty of options for the imbibers, like Ace Hotel Rooftop and Old St Records. Then there's Duke's Bar in Mayfair, which is a famous spot for a martini since Ian Fleming used to hang out there when he was writing James Bond novels.\n\nVisit a museum. The Tate Modern offers free entry and an excellent view of the city. It's on the south side of the Thames, and you can wander from there to the Shakespeare Globe. The National Portrait Gallery will keep you entertained, even though it really is home to all portraits, but you can learn a lot about British history by reading through the biographies of public figures featured. I also recommend seeing which artist's work the Hayward Gallery at the Southbank Centre is exhibiting, since it's an excellent space. The Tower of London is a classic for visitors: the castle is a World Heritage Site and where you need to go if you want to admire the Crown Jewels.\n\nSee a show. If you live or often see Broadway shows in New York, this might be less exciting to you, but London shows are relatively easy to secure tickets for, and a great activity if you're interested in experiencing even more British culture.\n\nShop. Don't miss the famous Harrod's, the iconic department store with a iconic food floor. Liberty is another well-known London department store. Less expensive, and known for their stationary.

This contact creates an excitement and uncertainty among the fans, as you want to see what will happen on each play.  Finally, football is enjoyable to watch whether you are in person or watching on TV.",

        "question": "Extract the name of the comedy films that Cage performed in. Separate them with a comma.",
        "evidence": "Cage made his acting debut in the 1981 television pilot The Best of Times, which was never picked up by ABC. His film debut followed in 1982, with a minor role as an unnamed co-worker of Judge Reinhold's character in the coming-of-age film Fast Times at Ridgemont High, having originally auditioned for Reinhold's part. His experience on the film was marred by cast members endlessly quoting his uncle's films, which inspired him to change his name. Cage's first starring role came opposite Deborah Foreman in the romantic comedy Valley Girl (1983), in which he played a punk who falls in love with the titular valley girl, a plot loosely inspired by Romeo and Juliet. The film was a modest box office success and has been branded a cult classic. He auditioned for the role of Dallas Winston in his uncle's film The Outsiders, based on S.E. Hinton's novel, but lost to Matt Dillon. Cage, however, would co-star in Coppola's adaptation of another Hinton novel, Rumble Fish, in that year.\n\nIn 1984, Cage appeared in three period films, none of which fared well at the box office. In the drama, Racing with the Moon (1984), Cage featured opposite Sean Penn as friends who are awaiting deployment to the U.S. Marine Corps. Coppola's crime drama The Cotton Club saw him play a fictionalized version of mob hitman Vincent \"Mad Dog\" Coll, earning praise from critic Paul Attanasio for \"artully  his few moments to sketch a brawny, violent thug\". His final release of the year was Alan Parker's drama Birdy, in which he starred with Matthew Modine as two close friends and their trauma inflicted by serving in the Vietnam War. Cage lost weight for the role and had two of his front teeth pulled out to appear disfigured. Despite massively underperforming at the box office, the film, and Cage and Modine's performances, received positive reviews, with The New York Times critic Janet Maslin writing, \"Mr. Cage very sympathetically captures Al's urgency and frustration. Together, these actors work miracles with what might have been unplayable.\"\n\nIn 1986, Cage starred in the little-seen Canadian sports drama The Boy in Blue and his uncle's fantasy comedy Peggy Sue Got Married (1987) as the husband to Kathleen Turner's character, who has travelled back in time to their high school days. He then starred in the Coen brothers' crime comedy Raising Arizona (1987) as a dim-witted ex-con. Cage's biggest breakthrough came in 1987 with the romantic comedy Moonstruck, in which he starred alongside Cher as a hot-tempered baker who falls in love with his estranged brother's widowed fiancé. The film was a hit with critics and audiences alike, earning Cage a Golden Globe nomination for Best Actor – Motion Picture Musical or Comedy  In his retrospective review, Roger Ebert wrote that he felt Cage's performance was worthy of an Oscar.",

        "question": "What do the classes mean in OWL?",
        "answer": "Classes denote sets of individuals and properties link two individuals or an individual and a data value along a property.",
        "evidence": "OWL BIBREF15 is the de-facto standard for machine processable and interoperable ontologies on the SW. In its second version, OWL is equivalent to the description logic $\\mathcal {SROIQ}(D)$. Such expressiveness has a higher computational cost but allows the development of interesting applications such as automated reasoning BIBREF16. OWL 2 ontologies consist of the following three different syntactic categories:\nEntities, such as classes, properties, and individuals, are identified by IRIs. They form the primitive terms and constitute the basic elements of an ontology. Classes denote sets of individuals and properties link two individuals or an individual and a data value along a property. For example, a class :Animal can be used to represent the set of all animals. Similarly, the object property :childOf can be used to represent the parent-child relationship and the data property :birthDate assigns a particular birth date to an individual. Finally, the individual :Alice can be used to represent a particular person called \"Alice\".\nExpressions represent complex notions in the domain being described. For example, a class expression describes a set of individuals in terms of the restrictions on the individuals' characteristics. OWL offers existential (SOME) or universal (ONLY) qualifiers and a variety of typical logical constructs, such as negation (NOT), other Boolean operators (OR, AND), and more constructs such as cardinality restriction (MIN, MAX, EXACTLY) and value restriction (VALUE), to create class expressions. Such constructs can be combined in arbitrarily complex class expressions CE according to the following grammar\nwhere A is an atomic class, C and D are class expressions, R is an object property, a as well as a$_1$ to a$_m$ with $\\texttt {m} \\ge 1$ are individuals, and $\\texttt {n} \\ge 0$ is an integer.\nAxioms are statements that are asserted to be true in the domain being described. Usually, one distinguish between (1) terminological and (2) assertional axioms. (1) terminological axioms are used to describe the structure of the domain, i.e., the relationships between classes resp. class expressions. For example, using a subclass axiom (SubClassOf:), one can state that the class :Koala is a subclass of the class :Animal. Classes can be subclasses of other classes, thus creating a taxonomy. In addition, axioms can arrange properties in hierarchies (SubPropertyOf:) and can assign various characteristics (Characteristics:) such as transitivity or reflexivity to them. (2) Assertional axioms formulate facts about individuals, especially the classes they belong to and their mutual relationships. OWL can be expressed in various syntaxes with the most common computer readable syntax being RDF/XMLA more human-readable format is the MOS BIBREF17. For example, the class expression that models people who work at a university that is located in Spain could be as follows in MOS:\nLikewise, expressing that every professor works at a university would read as\nOWL 2 ontologies consist of Entities, Expressions and Axioms as introduced in subsec:owl. While both expressions and axioms can be mapped to RDF, i.e. into a set of RDF triples, using this mapping and applying the triple-based verbalization on it would lead to a non-human understandable text in many cases. For example, the intersection of two classes :A and :B can be represented in RDF by the six triples\nThe verbalization of these triples would result in Something that is a class and the intersection of something whose first is A and whose rest is something whose first is B and whose rest ist nil., which is obviously far away from how a human would express it in NL. Therefore, generating NL from OWL requires a different procedure based on its syntactic categories, OWL expressions and OWL axioms. We show the general rules for each of them in the following.\nIn theory, class expressions can be arbitrarily complex, but as it turned out in some previous analysis BIBREF22, in practice they seldom arise and can be seen as some corner cases. For example, an ontology could contain the following class expression about people and their birth place:\nClass expressions do have a tree-like structure and can simply be parsed into a tree by means of the binary OWL class expressions constructors contained in it. For our example, this would result in the following tree:\nevery tree node/.style=align=center,anchor=base,font=, edge from parent/.style= thick, draw, edge from parent path=(.south) – +(0,-8pt) -| () frontier/.style=distance from root=9 [.AND Person [.SOME birthPlace [.AND City [.VALUE locatedIn France ] ] ] ]\nSuch a tree can be traversed in post-order, i.e. sub-trees are processed before their parent nodes recursively. For the sake of simplicity, we only process sub-trees that represent proper class expression in our example, i.e. we omit birthPlace, locatedIn, and France. Moreover and again for simplicity, we'll explain the transformation process by starting from the right-hand side of the tree. Thus, in our example we begin with the class expression City which is transformed to everything that is a city and locatedIn VALUE France resulting in everything that is located in France by application of a rule. Both class expressions are used in the conjunction City AND locatedIn VALUE France. Thus, the next step would be to merge both phrases. An easy way is to use the coordinating conjunction and, i.e. everything that is a city and everything that is located in France. Although the output of this transformation is correct, it still contains unnecessarily redundant information. Therefore, we apply the aggregation procedure described in subsec:grouping, i.e. we get everything that is a city and located in France. Yet, the aggregation can still be improved: if there is any atomic class in the conjunction, we know that this is more specific than the placeholder everything. Thus, we can replace it by the plural form of the class, finally resulting in cities that are located in France. The same procedure is applied for its parent class expression being the existential restriction\nThis will be transformed to everything whose birth place is a city that is located in France. Note, that we used the singular form here, assuming that the property birthPlace is supposed to be functional in the ontology. In the last step, we process the class expression Person, which gives us everything that is a person. Again, due to the conjunction we merge this result with with the previous one, such that in the end we get people whose birth place is a city that is located in France.\nAs we described in sec:owl, OWL axioms can roughly be categorized into terminological and assertional axioms. Therefore, we have different procedures for processing each category:\nAssertional Axioms (ABox Axioms) - Most assertional axioms assert individuals to atomic classes or relate individuals to another individual resp. literal value. For example, axioms about the type as well as birth place and birth date of Albert Einstein can be expressed by\nThose axioms can simply be rewritten as triples, thus, we can use the same procedure as we do for triples (sec:singletriple). Converting them into NL gives us Albert Einstein is a person whose birth place is Ulm and whose birth date is 14 March 1879. OWL also allows for assigning an individual to a complex class expression. In that case we'll use our conversion of OWL class expressions as described in subsec:owlce.\nTerminological Axioms (TBox Axioms) - According to power2010, most of the terminological axioms used in ontologies are subclass axioms. By definition, subclass and superclass can be arbitrarily complex class expressions $\\texttt {CE}_1$ and $\\texttt {CE}_2$, i.e. [language=manchester,mathescape=true]CE$_1$ SubClassOf CE$_2$, but in praxis it is quite often only used with atomic classes as subclass or even more simple with the superclass also beeing an atomic class. Nevertheless, we support any kind of subclass axiom and all other logical OWL axioms in LD2NL. For simplicity, we outline here how we verbalize subclass axioms in LD2NL. The semantics of a subclass axiom denotes that every individual of the subclass also belongs to the superclass. Thus, the verbalization seems to be relatively straightforward, i.e. we verbalize both class expressions and follow the template : every $\\rho (\\texttt {\\texttt {CE}$1$})$ is a $\\rho (\\texttt {\\texttt {CE}$2$})$. Obviously, this works pretty well for subclass axioms with atomic classes only. For example, the axiom\nis verbalized as every scientist is a person.\nThis work was supported by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) through the projects LIMBO (no. 19F2029I) and OPAL (no. 19F2028A).

        "answer": "We have moved details on using SVD to obtain n>1 spanning vectors to Section 3.2. We have included additional experiments on the selection of n across different datasets and $k$ in Table 9. We observe in general that setting n = k x  # classes for k≥ 5 obtains best or close-to-best performance, while the choice at k=1 is dataset-dependent.",
        "evidence": "We compare our method with the baseline source models, as well as with test-time adaptation methods that also augment only batch normalization layers namely Test-time BN and the state-of-the-art Tent) that adapts BN parameters by entropy minimization with default hyperparameters i.e. Adam or SGD with momentum with mini-batch size 128 and learning rate 0.001. We point out that test-time adaptation methods are not designed for the same setting and are not directly comparable with our proposed method. We include them to show empirically that adapting with a few labelled samples can achieve better and more reliable classification performance than adapting with a large streaming dataset. On all datasets, we set mini-batch size as 32, and use Adam optimizer with 0.001 learning rate for finetuning LCCS. For larger support sets at k ≥ 5, we use the nearest-centroid-classifier as in instead of source classifier. We set n = k × # classes for µ LCCS for Camelyon17 and VisDA, and n = 1 otherwise.\nFrom Table, our proposed method improves over source models even with a single example per class for all datasets evaluated, and overall is comparable to or better than Test-time BN and Tent when k ≥ 5. We observe that Tent performance is dependent on optimizer choice, with Adam outperforming SGD by approximately 2% in PACS and SGD outperforming Adam by as much as 39.2% on VisDA. Since the better performing optimizer is dataset-dependent, this makes the practical usage of Tent challenging. For PACS, our proposed method performs better than the best case of Tent when support set has 5 or 10 samples per class. For Camelyon17, all BN adaptation methods improve over source model accuracy by at least 18% in the best scenario, implying that replacing source BN statistics with target BN statistics is effective in addressing domain shift in this dataset. For the 182-class iWildCam dataset, the test dataset is imbalanced; 102 classes have at least 1 sample, and only 87 classes have at least 5 samples. Hence to prevent introducing more class imbalance in the adaptation and evaluation processes, we only evaluate the setting where k = 1, which translates to 102 support samples. Our proposed method improves slightly over source model, while all test-adaptation methods obtained lower F1-score than the original baseline performance.\nSimilarly for VisDA, our proposed method obtains the best target performance. In particular, all test-time adaptation methods result in worse performance than original source model. We provide standard errors of results in Table in Appendix Section C.2.\nEffect of test batches: Although test-time adaptation methods can improve the source model without supervision of labelled samples, their performance relies on streaming conditions and severely degrades with smaller mini-batch size and class-imbalanced mini-batches as shown in Table, and in detail in Appendix Section C.2. We constructed long-tailed imbalanced PACS and VisDA following the procedure in, where sample sizes decay exponentially from the first to last class and α is the ratio of the largest to smallest class. The good performance of test-time methods is  dependent on having large, evenly classes-distributed mini-batches. On the contrary, our proposed method is not dependent on streaming conditions and can more reliably adapt to the target domain.\nWe provide further analysis of our proposed method. Additional analysis on LCCS parameter initialization and cross-entropy objective can be found in Appendix Section D.\nAblation study. We conduct ablation study on the initialization and gradient update stages of the proposed method in Table. Each stage independently improves the base performance on VisDA dataset, showing that both stages help the source model adapt to the target domain.\nWe further experiment with different algorithm design choices in optimizing LCCS parameters on VisDA. Initializing LCCS with values tied across all BN layers (67.0% avg prec) is better than greedily initializing each BN layer sequentially from the shallowest layer first (66.1% avg prec). In the gradient update stage, linear combination of statistics (67.0% avg prec) in Equations 4 performs better than restricting to a convex combination (66.1% avg prec).\nApproximation with n > 1. We investigate increasing the number n of spanning vectors used to represent the target domain in Equation 3. From Table, when support set is larger, more vectors can be used to represent the target domain and performance improves with a larger number of adaptable LCCS parameters on Camelyon17 and VisDA. We observe in general that setting n = k × # classes for k ≥ 5 obtains best or close-to-best performance, while the choice at k = 1 is dataset-dependent.\nFor larger support sets at k ≥ 5, we use the nearest-centroid-classifier as in (Triantafillou et al., 2021) instead of source classifier. We set n = k × # classes for µLCCS for Camelyon17 and VisDA, and n = 1 otherwise.****From Table 9, when support set is larger, more vectors can be used to represent the target domain and performance improves with a larger number of adaptable LCCS parameters on Camelyon17 and VisDA.

In the context of question answering, question classification allows automated systems to intelligently target their inference systems to domain-specific solvers capable of addressing specific kinds of questions and problem solving methods with high confidence and answer accuracy BIBREF0 , BIBREF1 .\nTo date, question classification has primarily been studied in the context of open-domain TREC questions BIBREF2 , with smaller recent datasets available in the biomedical BIBREF3 , BIBREF4 and education BIBREF5 domains. The open-domain TREC question corpus is a set of 5,952 short factoid questions paired with a taxonomy developed by Li and Roth BIBREF6 that includes 6 coarse answer types (such as entities, locations, and numbers), and 50 fine-grained types (e.g. specific kinds of entities, such as animals or vehicles). While a wide variety of syntactic, semantic, and other features and classification methods have been applied to this task, culminating in near-perfect classification performance BIBREF7 , recent work has demonstrated that QC methods developed on TREC questions generally fail to transfer to datasets with more complex questions such as those in the biomedical domain BIBREF3 , likely due in part to the simplicity and syntactic regularity of the questions, and the ability for simpler term-frequency models to achieve near-ceiling performance BIBREF8 . In this work we explore question classification in the context of multiple choice science exams. Standardized science exams have been proposed as a challenge task for question answering BIBREF9 , as most questions contain a variety of challenging inference problems BIBREF10 , BIBREF11 , require detailed scientific and common-sense knowledge to answer and explain the reasoning behind those answers BIBREF12 , and questions are often embedded in complex examples or other distractors.

Our long-term interest is in developing methods that intelligently target their inferences to generate both correct answers and compelling human-readable explanations for the reasoning behind those answers.

Therefore, each capsule can capture many characteristics among the entries at the corresponding dimension in the embedding triple. These characteristics are generalized into one capsule in the second layer which produces a vector output whose length is used as the score for the triple.\nThe first capsule layer consists of INLINEFORM0 capsules, for which each capsule INLINEFORM1 has a vector output INLINEFORM2 . Vector outputs INLINEFORM3 are multiplied by weight matrices INLINEFORM4 to produce vectors INLINEFORM5 which are summed to produce a vector input INLINEFORM6 to the capsule in the second layer. The capsule then performs the non-linear squashing function to produce a vector output INLINEFORM7 : DISPLAYFORM0 \nwhere INLINEFORM0 , and INLINEFORM1 are coupling coefficients determined by the routing process as presented in Algorithm SECREF2 . Because there is one capsule in the second layer, we make only one difference in the routing process proposed by BIBREF16 , for which we apply the INLINEFORM2 in a direction from all capsules in the previous layer to each of capsules in the next layer.\n[ht] 1.25\nall capsule i INLINEFORM0 the first layer INLINEFORM1 0 INLINEFORM2 = 1, 2, ..., m INLINEFORM3 INLINEFORM4 \n INLINEFORM0 \nall capsule i INLINEFORM0 the first layer INLINEFORM1 The routing process is extended from BIBREF16 .\nWe illustrate our proposed model in Figure FIGREF1 where embedding size: INLINEFORM0 , the number of filters: INLINEFORM1 , the number of neurons within the capsules in the first layer is equal to INLINEFORM2 , and the number of neurons within the capsule in the second layer: INLINEFORM3 . The length of the vector output INLINEFORM4 is used as the score for the input triple.\nFormally, we define the score function INLINEFORM0 for the triple INLINEFORM1 as follows: DISPLAYFORM0 \nwhere the set of filters INLINEFORM0 is shared parameters in the convolution layer; INLINEFORM1 denotes a convolution operator; and INLINEFORM2 denotes a capsule network operator. We use the Adam optimizer BIBREF19 to train CapsE by minimizing the loss function BIBREF14 , BIBREF15 as follows: DISPLAYFORM0 \n INLINEFORM0 \nhere INLINEFORM0 and INLINEFORM1 are collections of valid and invalid triples, respectively. INLINEFORM2 is generated by corrupting valid triples in INLINEFORM3 .\nWe build our CapsE with two single capsule layers for a simplified architecture.",

Selection-based QA implies a family of tasks that find answer contexts from large data given questions in natural language. Three tasks have been proposed for selection-based QA. Given a document, answer extraction BIBREF0 , BIBREF1 finds answer phrases whereas answer selection BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 and answer triggering BIBREF6 , BIBREF7 find answer sentences instead, although the presence of the answer context is not assumed within the provided document for answer triggering but it is for the other two tasks. Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension.

Although all of these corpora target on selection-based QA, they are designed for different purposes such that it is important to understand the nature of these corpora so a better use of them can be made. In this paper, we make both intrinsic and extrinsic analyses of four latest corpora based on Wikipedia, WikiQA, SelQA, SQuAD, and InfoboxQA. We first give a thorough intrinsic analysis regarding contextual similarities, question types, and answer categories (Section SECREF2 ).

        "question": "Why are cats better than dogs?",
        "evidence": "",
        "answer": "First, let me say that the question represents my own, personal, subjective opinion.  I also adore dogs, just not as much as cats.  I am fully a cat person.\nThe cat, though.  I am humbled by the task of trying to accurately capture in words the mystery of these beautiful creatures who have chosen to enslave humans.  So instead, because I am also trying to train a model, I will just use a lot of unnecessary adjectives and that will have to do.\nCats have been around humans for a long long time.  I remember as a kid having a book that talked about how in Ancient Egypt cats were revered as holy creatures and kept in luxury in temples of Baast.  The first known evidence of cat domestication is the excavation of a Neolithic grave in Cyprus.  The thing I adore about cats is that they basically haven’t bothered to change themselves since then.  They just carried on being slightly aloof and mysterious, but also affectionate and playful when they feel like it.  And imperious and demanding, of course.  \nCats are incredible communicators.  They have learned to meow at humans because they realised we respond to meows, even though you will very rarely hear a cat meow at another cat (the indignity!).  Meows and chirps are the special condescending language cats developed to communicate with an inferior species.  My own cat can make crystal clear what he wants with looks, body language and the odd meow when he can be bothered.  He is also a total drama queen and obviously manipulative.  If he wants food he will try the ‘I’m hungry’ meow first and if that doesn’t work we get the full on “I’m starving, this is a tragedy, I will die almost immediately if I don’t get food right now”.  I am full of respect for the cats’ ability to manipulate humans and the shamelessness with which they do this.\nCats are also super independent compared to dogs.  No need for walks, no need for the dreaded poo bags, no need for expensive care every time you want to go away for a night.  They love their humans but 100% on their own terms.  \nCats are adorable and cute.  I can’t stress this enough.  Ever seen a cat roll over so you can see its fluffy belly.  How can you not melt.  Ever had a cat make biscuits on your lap (or in the air).  Cuteness overload.  They are even cute when they are mad.  And most cats I’ve met know how to gently tell you what affection is allowed and what isn’t (illegal belly rubs).  They will bat you with a paw, but the claws will be in.  And a cat purring on your lap is the single most relaxing thing in the whole world.\nThe Swedish word for ‘cat’ is ‘kattepus’.  That in itself seems a really great reason why cats are better than dogs.\nThe last word goes to Terry Pratchett, author of the Discworld novels, who wrote ‘In ancient times cats were worshipped as gods; they have not forgotten this’.

Get this most important tool first.\n- A 1” wide tape measure. Get one that’s 25ft long. The wide width makes it easier for one person to measure long runs or furniture by themselves. A 25ft length will be long enough to measure the longest wall of most rooms and any piece of furniture.\n- A small level to evenly hang pictures and anything else you can think of. It should be about 10” to 12” long.\n- A pair of #2 Phillips head and #2 flat tip screwdrivers. Or, a ratcheting screwdriver with a set of replaceable screwdriver tips. To tighten loose screws or assemble furniture.\n- A folding step-stool that has two or three steps, and can support two to three hundred pounds. To quickly and safely reach those high shelves, hang pictures, and get close to things that are too high off the ground for you to reach standing in your flat shoes.\n- A comfortable-in-hand hammer, to drive nails for hanging pictures, gently tap things together, or break things apart. A wooden handled, curved-claw hammer that weighs between 12oz-16oz will serve most users well. When pulling nails, place a thin piece of wood between the hammerhead and delicate surfaces such as sheetrock to avoid damaged. Good hardware stores carry both.\n- A pair of adjustable wrenches for tightening just about anything. You’ll often need a pair of\nwrenches to both hold and tighten the same fastener. A smaller 8” and larger 10” adjustable\nwrenches make a good combination for most tasks.\n- A utility knife and a package of quality blades. To safely cut open boxes and other packaging, as well as trim paper, fabrics, textiles, wood…etc. The knife should feel secure in your hand and have a large, easy to turn knob to open the knife to change blades. Buy a package of high-quality name brand replacement blades to keep on hand.\n- An extra power receptacle for an emergency or unplanned usage. Always have an extra on\nhand…you will need it.\n- Hex wrenches. Also called Allen keys. You’ll need these mainly for assembling things like\nfurniture. These come in both metric and imperial standard sizes. Both are useful to have, but if you only buy one set, make it metric, as it’s the most common type of fastener used to assemble furniture.\n- A stud finder. Stud finders help you locate the wall studs hidden behind the sheetrock. You’ll need to know where the wall studs are in order to know which fasteners you can use.\n- A tool box or bag. The only rule here is that the bag needs to hold all of your tools. So, you should probably buy this after you’ve owned and used a few of the tools listed previously, and have a better idea how you’d like to store them, carry them and access them.\n- A cordless drill and impact driver set, if you can afford it. All the other tools are more important, but these two tools are incredibly useful and make many jobs go faster and more pleasantly. The drill is for drilling. The impact driver is for driving or removing screws and other common fasteners. They look similar, but they are 2 different tools, each giving the user the right kinds of power and feedback required for the job each is designed for.

        "question": "What cells does the selected sharing layer compose of?",
        "answer": "Gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks.",
        "evidence": "In recent years, the proliferation of fake news with various content, high-speed spreading, and extensive influence has become an increasingly alarming issue. A concrete instance was cited by Time Magazine in 2013 when a false announcement of Barack Obama's injury in a White House explosion “wiped off 130 Billion US Dollars in stock value in a matter of seconds\". Other examples, an analysis of the US Presidential Election in 2016 BIBREF0 revealed that fake news was widely shared during the three months prior to the election with 30 million total Facebook shares of 115 known pro-Trump fake stories and 7.6 million of 41 known pro-Clinton fake stories. Therefore, automatically detecting fake news has attracted significant research attention in both industries and academia.\nMost existing methods devise deep neural networks to capture credibility features for fake news detection. Some methods provide in-depth analysis of text features, e.g., linguistic BIBREF1, semantic BIBREF2, emotional BIBREF3, stylistic BIBREF4, etc. On this basis, some work additionally extracts social context features (a.k.a. meta-data features) as credibility features, including source-based BIBREF5, user-centered BIBREF6, post-based BIBREF7 and network-based BIBREF8, etc. These methods have attained a certain level of success. Additionally, recent researches BIBREF9, BIBREF10 find that doubtful and opposing voices against fake news are always triggered along with its propagation. Fake news tends to provoke controversies compared to real news BIBREF11, BIBREF12. Therefore, stance analysis of these controversies can serve as valuable credibility features for fake news detection.\nThere is an effective and novel way to improve the performance of fake news detection combined with stance analysis, which is to build multi-task learning models to jointly train both tasks BIBREF13, BIBREF14, BIBREF15. These approaches model information sharing and representation reinforcement between the two tasks, which expands valuable features for their respective tasks. However, prominent drawback to these methods and even typical multi-task learning methods, like the shared-private model, is that the shared features in the shared layer are equally sent to their respective tasks without filtering, which causes that some useless and even adverse features are mixed in different tasks, as shown in Figure FIGREF2(a). By that the network would be confused by these features, interfering effective sharing, and even mislead the predictions.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure FIGREF2(b)) to detect fake news by joining stance detection task. Specifically, we introduce a selected sharing layer into each task after the shared layer of the model for filtering shared features. The selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks. Besides, to better capture long-range dependencies and improve the parallelism of the model, we apply transformer encoder module BIBREF16 to our model for encoding input representations of both tasks. Experimental results reveal that the proposed model outperforms the compared methods and gains new benchmarks.\nIn summary, the contributions of this paper are as follows:\nWe explore a selected sharing layer relying on gate mechanism and attention mechanism, which can selectively capture valuable shared features between tasks of fake news detection and stance detection for respective tasks.\nThe transformer encoder is introduced into our model for encoding inputs of both tasks, which enhances the performance of our method by taking advantages of its long-range dependencies and parallelism.\nExperiments on two public, widely used fake news datasets demonstrate that our method significantly outperforms previous state-of-the-art methods.\nThe selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks.",

It traverses south through the states of Maharashtra, Goa, Karnataka and Kerala. Major gaps in the range are the Goa Gap, between the Maharashtra and Karnataka sections, and the Palghat Gap on the Tamil Nadu and Kerala border between the Nilgiri Mountains and the Anaimalai Hills. The mountains intercept the rain-bearing westerly monsoon winds, and are consequently an area of high rainfall, particularly on their western side. The dense forests also contribute to the precipitation of the area by acting as a substrate for condensation of moist rising orographic winds from the sea, and releasing much of the moisture back into the air via transpiration, allowing it to later condense and fall again as rain.[citation needed]\n\nThe northern portion of the narrow coastal plain between the Western Ghats and the Arabian Sea is known as the Konkan, the central portion is called Kanara and the southern portion is called Malabar. The foothill region east of the Ghats in Maharashtra is known as Desh, while the eastern foothills of the central Karnataka state is known as Malenadu. The range is known as Sahyadri in Maharashtra and Karnataka. The Western Ghats meet the Eastern Ghats at the Nilgiri mountains in northwestern Tamil Nadu. The Nilgiris connect the Biligiriranga Hills in southeastern Karnataka with the Shevaroys and Tirumala hills. South of the Palghat Gap are the Anamala Hills, located in western Tamil Nadu and Kerala with smaller ranges further south, including the Cardamom Hills, then Aryankavu pass, and Aralvaimozhi pass near Kanyakumari. The range is known as Sahyan or Sahian in Kerala. In the southern part of the range is Anamudi (2,695 metres (8,842 ft)), the highest peak in the Western Ghats.

The breadth of tasks allows to fairly measure generalization to a wide area of different domains, testing the general-purpose quality (universality) of all competing sentence embeddings. For downstream supervised evaluations, sentence embeddings are combined with logistic regression to predict target labels. In the unsupervised evaluation for sentence similarity, correlation of the cosine similarity between two embeddings is compared to human annotators.\nDownstream Supervised Evaluation. Sentence embeddings are evaluated for various supervised classification tasks as follows. We evaluate paraphrase identification (MSRP) BIBREF25 , classification of movie review sentiment (MR) BIBREF26 , product reviews (CR) BIBREF27 , subjectivity classification (SUBJ) BIBREF28 , opinion polarity (MPQA) BIBREF29 and question type classification (TREC) BIBREF30 . To classify, we use the code provided by BIBREF22 in the same manner as in BIBREF16 . For the MSRP dataset, containing pairs of sentences INLINEFORM0 with associated paraphrase label, we generate feature vectors by concatenating their Sent2Vec representations INLINEFORM1 with the component-wise product INLINEFORM2 . The predefined training split is used to tune the L2 penalty parameter using cross-validation and the accuracy and F1 scores are computed on the test set. For the remaining 5 datasets, Sent2Vec embeddings are inferred from input sentences and directly fed to a logistic regression classifier. Accuracy scores are obtained using 10-fold cross-validation for the MR, CR, SUBJ and MPQA datasets. For those datasets nested cross-validation is used to tune the L2 penalty. For the TREC dataset, as for the MRSP dataset, the L2 penalty is tuned on the predefined train split using 10-fold cross-validation, and the accuracy is computed on the test set.\nUnsupervised Similarity Evaluation. We perform unsupervised evaluation of the learnt sentence embeddings using the sentence cosine similarity, on the STS 2014 BIBREF31 and SICK 2014 BIBREF32 datasets. These similarity scores are compared to the gold-standard human judgements using Pearson's INLINEFORM0 BIBREF33 and Spearman's INLINEFORM1 BIBREF34 correlation scores.

The diet of the kiwi bird consists of woodlice, millipedes, centipedes, slugs, snails, spiders, insects, seeds, berries, and plant material. The Kiwi is a solitary animal that makes holes as hiding places for sleeping with its feet. The kiwi was created with a small, thin beak to get into crevices. This animal is almost extinct, and is important to the native ecosystem; the kiwi keeps the bug population down and is hunted by natural predators. New Zealand protects its most prized bird, for it is the only flightless bird in that ecosystem and a national symbol.

        "evidence": "Development of an Apple smartphone began in 2004, when Apple started to gather a team of 1,000 employees led by hardware engineer Tony Fadell, software engineer Scott Forstall, and design officer Jony Ive, to work on the highly confidential \"Project Purple\".\n\nThen-Apple CEO Steve Jobs steered the original focus away from a tablet (which was later revisited in the form of the iPad) towards a phone. Apple created the device during a secretive collaboration with Cingular Wireless (later renamed AT&T Mobility) at the time—at an estimated development cost of US$150 million over thirty months.According to Jobs in 1998, the \"i\" word in \"iMac\" (and therefore \"iPod\", \"iPhone\" and \"iPad\") stands for internet, individual, instruct, inform, and inspire.\n\nApple rejected the \"design by committee\" approach that had yielded the Motorola ROKR E1, a largely unsuccessful \"iTunes phone\" made in collaboration with Motorola. Among other deficiencies, the ROKR E1's firmware limited storage to only 100 iTunes songs to avoid competing with Apple's iPod nano. Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house, a rare practice at the time, and paid Apple a fraction of its monthly service revenue (until the iPhone 3G), in exchange for four years of exclusive U.S. sales, until 2011.\n\nJobs unveiled the first-generation iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Center in San Francisco. The iPhone incorporated a 3.5-inch multi-touch display with few hardware buttons, and ran the iPhone OS operating system with a touch-friendly interface, then marketed as a version of Mac OS X. It launched on June 29, 2007, at a starting price of US$499 in the United States, and required a two-year contract with AT&T.\n\nOn July 11, 2008, at Apple's Worldwide Developers Conference (WWDC) 2008, Apple announced the iPhone 3G, and expanded its launch-day availability to twenty-two countries, and it was eventually released in 70 countries and territories. The iPhone 3G introduced faster 3G connectivity, and a lower starting price of US$199 (with a two-year AT&T contract). Its successor, the iPhone 3GS, was announced on June 8, 2009, at WWDC 2009, and introduced video recording functionality.\n\nFirst iPhone on display under glass at the January 2007 Macworld show\nThe iPhone 4 was announced on June 7, 2010, at WWDC 2010, and introduced a redesigned body incorporating a stainless steel frame and a rear glass panel. At release, the iPhone 4 was marketed as the \"world's thinnest smartphone\"; it uses the Apple A4 processor, being the first iPhone to use an Apple custom-designed chip. It introduced the Retina display, having four-times the display resolution of preceding iPhones, and was the highest-resolution smartphone screen at release; a front-facing camera was also introduced, enabling video calling functionality via FaceTime.\n\nUsers of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way, and this issue was nicknamed \"antennagate\". In January 2011, as Apple's exclusivity agreement with AT&T was expiring, Verizon announced that they would be carrying the iPhone 4, with a model compatible with Verizon's CDMA network releasing on February 10.\n\nThe iPhone 4S was announced on October 4, 2011, and introduced the Siri virtual assistant, a dual-core A5 processor, and an 8 megapixel camera with 1080p video recording functionality. The iPhone 5 was announced on September 12, 2012, and introduced a larger 4-inch screen, up from the 3.5-inch screen of all previous iPhone models, as well as faster 4G LTE connectivity. It also introduced a thinner and lighter body made of aluminum alloy, and the 30-pin dock connector of previous iPhones was replaced with the new, reversible Lightning connector.\n\nThe iPhone 5S and iPhone 5C were announced on September 10, 2013. The iPhone 5S included a 64-bit A7 processor, becoming the first ever 64-bit smartphone; it also introduced the Touch ID fingerprint authentication sensor. The iPhone 5C was a lower-cost device that incorporated hardware from the iPhone 5, into a series of colorful plastic frames.\n\nOn September 9, 2014, Apple introduced the iPhone 6 and iPhone 6 Plus, and included significantly larger screens than the iPhone 5S, at 4.7-inch and 5.5-inch respectively; both models also introduced mobile payment technology via Apple Pay. Optical image stabilization was introduced to the 6 Plus' camera. The Apple Watch was also introduced on the same day, and is a smartwatch that operates in conjunction with a connected iPhone. Some users experienced bending issues from normal use with the iPhone 6 and 6 Plus, particularly on the latter model, and this issue was nicknamed \"bendgate\".\n\nThe iPhone 6S and 6S Plus were introduced on September 9, 2015, and included a more bend-resistant frame made of a stronger aluminum alloy, as well as a higher resolution 12-megapixel main camera capable of 4K video recording. The first-generation iPhone SE was introduced on March 21, 2016, and was a low-cost device that incorporated newer hardware from the iPhone 6S, in the frame of the older iPhone 5S.\n\nThe iPhone 7 and 7 Plus were announced on September 7, 2016, which introduced larger camera sensors, IP67-certified water and dust resistance, and a quad-core A10 Fusion processor utilizing big.LITTLE technology; the 3.5mm headphone jack was removed, and was followed by the introduction of the AirPods wireless earbuds. Optical image stabilization was added to the 7's camera. A second telephoto camera lens was added on the 7 Plus, enabling two-times optical zoom, and \"Portrait\" photography mode which simulates bokeh in photos.\n\nThe iPhone 8, 8 Plus, and iPhone X were announced on September 12, 2017, in Apple's first event held at the Steve Jobs Theater in Apple Park. All models featured rear glass panel designs akin to the iPhone 4, wireless charging, and a hexa-core A11 Bionic chip with \"Neural Engine\" AI accelerator hardware. The iPhone X additionally introduced a 5.8-inch OLED \"Super Retina\" display with a \"bezel-less\" design, with a higher pixel density and contrast ratio than previous iPhones with LCD displays, and introduced a stronger frame made of stainless steel. It also introduced Face ID facial recognition authentication hardware, in a \"notch\" screen cutout, in place of Touch ID; the home button was removed to make room for additional screen space, replacing it with a gesture-based navigation system. At its US$999 starting price, the iPhone X was the most expensive iPhone at launch.\n\nThe iPhone XR, iPhone XS, and XS Max were announced on September 12, 2018. All models featured the \"Smart HDR\" computational photography system, and a significantly more powerful \"Neural Engine\".[ The XS Max introduced a larger 6.5-inch screen. The iPhone XR included a 6.1-inch LCD \"Liquid Retina\" display, with a \"bezel-less\" design similar to the iPhone X, but does not include a second telephoto lens; it was made available in a series of vibrant colors, akin to the iPhone 5C, and was a lower-cost device compared to the iPhone X and XS.\n\nThe iPhone 11, 11 Pro, and 11 Pro Max were announced on September 10, 2019. The iPhone 11 was the successor to the iPhone XR, while the iPhone 11 Pro and 11 Pro Max succeeded the iPhone XS and XS Max. All models gained an ultra-wide lens, enabling two-times optical zoom out, as well as larger batteries for longer battery life. The second-generation iPhone SE was introduced on April 17, 2020, and was a low-cost device that incorporated newer hardware from the iPhone 11, in the frame of the older iPhone 8, while retaining the home button and the Touch ID sensor.\n\nThe iPhone 12, 12 Mini, 12 Pro, and 12 Pro Max were announced via a livestream event on October 13, 2020. All models featured OLED \"Super Retina XDR\" displays, introduced faster 5G connectivity, and the MagSafe magnetic charging and accessory system; a slimmer flat-edged design was also introduced, which combined with stronger glass-ceramic front glass, added better drop protection compared to previous iPhones. The iPhone 12 Mini introduced a smaller 5.4-inch screen, while the 12 Pro and 12 Pro Max had larger screens of 6.1-inch and 6.7-inch respectively. The iPhone 12 Pro and 12 Pro Max additionally added a Lidar sensor for better accuracy in augumented reality (AR) applications.\n\nThe iPhone 13, 13 Mini, 13 Pro, and 13 Pro Max were announced via a livestream event on September 14, 2021. All models featured larger camera sensors, larger batteries for longer battery life, and a narrower \"notch\" screen cutout. The iPhone 13 Pro and 13 Pro Max additionally introduced smoother adaptive 120 Hz refresh rate \"ProMotion\" technology in its OLED display, and three-times optical zoom in the telephoto lens. The low-cost third-generation iPhone SE was introduced on March 8, 2022, and incorporated the A15 Bionic chip from the iPhone 13, but otherwise retained similar hardware to the second-generation iPhone SE.\n\nThe iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max were announced on September 7, 2022. All models introduced satellite phone emergency calling functionality. The iPhone 14 Plus introduced the large 6.7-inch screen size, first seen on the iPhone 12 Pro Max, into a lower-cost device. The iPhone 14 Pro and 14 Pro Max additionally introduced a higher-resolution 48-megapixel main camera, the first increase in megapixel count since the iPhone 6S; it also introduced always-on display technology to the lock screen, and an interactive status bar interface integrated in a redesigned screen cutout, entitled \"Dynamic Island\".",

        "answer": "An important general difference in the focus and purpose between machine learning and the traditional Exploratory Data Analysis (EDA) is that machine learning is more oriented towards applications than explaining the basic nature of the underlying phenomena. Machine Learning is relatively less concerned with identifying the specific relations between the involved variables. For example, uncovering the nature of the underlying functions or the specific types of interactive, multivariate dependencies between variables are not the main goal of machine learning. Instead, the focus is on producing a solution that can generate useful predictions. Machine Learning accepts among others a \"black box\" type approach to data exploration or knowledge discovery and uses not only the traditional Exploratory Data Analysis (EDA) techniques, but also such techniques as Neural Networks which can generate valid predictions but are not capable of identifying the specific nature of the interrelations between the variables on which the predictions are based.",

        "evidence": "Figure skating is a sport in which individuals, pairs, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, when contested at the 1908 Olympics in London. The Olympic disciplines are men's singles, women's singles,[note 1] pair skating, and ice dance; the four individual disciplines are also combined into a team event, first included in the Winter Olympics in 2014. The non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs (the short program and the free skate), which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves.\n\nFigure skaters compete at various levels from beginner up to the Olympic level (senior) at local, regional, sectional, national, and international competitions. The International Skating Union (ISU) regulates international figure skating judging and competitions. These include the Winter Olympics, the World Championships, the World Junior Championships, the European Championships, the Four Continents Championships, the Grand Prix series (senior and junior), and the ISU Challenger Series.\n\nThe sport is also associated with show business. Major competitions generally conclude with exhibition galas, in which the top skaters from each discipline perform non-competitive programs. Many skaters, both during and after their competitive careers, also skate in ice shows, which run during the competitive season and the off-season.",
        "answer": "Figure skating is one of the most difficult sports due to a number of reasons, including the precision needed to execute tricks, talent for performing required, and the costs involved in competing. The skill needed to perform tricks like the axel or double axel is already very high  and on top of that, figure skaters need to be good at performing their routines. In addition, the costs for practicing, buying good figure skates, and tailoring competition costumes can add up quickly.",

The joint's function is to transfer vibrations between the ossicles in the middle ear, which is perceived as sound. Contrary to other synovial joints the movement is very limited. All of the ossicles move more or less as a unit, at least at low frequencies.\n\nWhen the eardrum is moved inward due to sound vibrations, transferred through the outer ear, it transmits to the handle or manubrium of the malleus which is connected to the ear drum. The head of the malleus (caput mallei) moves with it and transfers energy/movement to the corpus of the incus (corpus incudis), which is located directly behind. The sound vibrations are then transferred to the stapes (stirrup) through the incudostapedial joint.",

First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary.",
        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nBy including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary.",

        "evidence": "To fully leverage the hierarchical structure of our encoder, we propose two variants of hierarchical attention mechanism to compute the context fed to the decoder module.\n$\\bullet $ Traditional Hierarchical Attention. As in BIBREF13, we hypothesize that a dynamic context should be computed in two steps: first attending to entities, then to records corresponding to these entities. To implement this hierarchical attention, at each decoding step $t$, the model learns a first set of attention scores $\\alpha _{i,t}$ over entities $e_i$ and a second set of attention scores $\\beta _{i,j,t}$ over records $r_{i,j}$ belonging to entity $e_i$. The $\\alpha _{i,t}$ scores are normalized to form a distribution over all entities $e_i$, and $\\beta _{i,j,t}$ scores are normalized to form a distribution over records $r_{i,j}$ of entity $e_i$. Each entity is then represented as a weighted sum of its record embeddings, and the entire data structure is represented as a weighted sum of the entity representations. The dynamic context is computed as:\nct = i=1I (i,t ( j i,j,t ri,j ))\nwhere i,t exp(dtWei) and i,j,t exp(dtWhi,j)\nwhere $\\mathbf {d_t}$ is the decoder hidden state at time step $t$, $\\mathbf {W}_{\\alpha } \\in \\mathbb {R}^{d\\times d}$ and $\\mathbf {W}_{\\beta } \\in \\mathbb {R}^{d\\times d}$ are learnt parameters, $ \\sum _i\\alpha _{i,t} = 1$, and for all $i \\in \\lbrace 1,...,I\\rbrace $ $\\sum _{j}\\beta _{i,j,t} = 1$.\n$\\bullet $ Key-guided Hierarchical Attention. This variant follows the intuition that once an entity is chosen for mention (thanks to $\\alpha _{i,t}$), only the type of records is important to determine the content of the description. For example, when deciding to mention a player, all experts automatically report his score without consideration of its specific value. To test this intuition, we model the attention scores by computing the $\\beta _{i,j,t}$ scores from equation (SECREF16) solely on the embedding of the key rather than on the full record representation $\\mathbf {h}_{i,j}$:\n\nPlease note that the different embeddings and the model parameters presented in the model components are learnt using Equation 1.\nTo fully leverage the hierarchical structure of our encoder, we propose two variants of hierarchical attention mechanism to compute the context fed to the decoder module. • Traditional Hierarchical Attention****Key-guided Hierarchical Attention",

They include harvests, wheat fields and general rural landmarks from the area, including The Old Mill (1888), one of seven canvases sent to Pont-Aven on 4 October 1888 in an exchange of works with Paul Gauguin, Émile Bernard, Charles Laval and others. The portrayals of Arles are informed by his Dutch upbringing; the patchworks of fields and avenues are flat and lacking perspective, but excel in their use of colour.\nIn March 1888 he painted landscapes using a gridded \"perspective frame\"; three of the works were shown at the annual exhibition of the Société des Artistes Indépendants. In April, he was visited by the American artist Dodge MacKnight, who was living nearby at Fontvieille. On 1 May 1888, for 15 francs per month, he signed a lease for the eastern wing of the Yellow House at 2 place Lamartine. The rooms were unfurnished and had been uninhabited for months.\nOn 7 May, Van Gogh moved from the Hôtel Carrel to the Café de la Gare, having befriended the proprietors, Joseph and Marie Ginoux. The Yellow House had to be furnished before he could fully move in, but he was able to use it as a studio. He wanted a gallery to display his work and started a series of paintings that eventually included Van Gogh's Chair (1888), Bedroom in Arles (1888), The Night Café (1888), Café Terrace at Night (September 1888), Starry Night Over the Rhone (1888), and Still Life: Vase with Twelve Sunflowers (1888), all intended for the decoration for the Yellow House.\nVan Gogh wrote that with The Night Café he tried \"to express the idea that the café is a place where one can ruin oneself, go mad, or commit a crime\". When he visited Saintes-Maries-de-la-Mer in June, he gave lessons to a Zouave second lieutenant – Paul-Eugène Milliet – and painted boats on the sea and the village. MacKnight introduced Van Gogh to Eugène Boch, a Belgian painter who sometimes stayed in Fontvieille, and the two exchanged visits in July.",

The generated hierarchy, a tree, provides information associated with the boundaries of the discourse segments and related to their importance and dependencies. The figure FIGREF1 shows an example of such a rethorical tree. In the rethorical parsing process, the text has been divided into five units. In the figure FIGREF1, the arrow that leaves the unit (2) towards the unit (1) symbolizes that the unit (2) is the satellite of the unit (1), which is the core in a “Concession” relationship. In turn, the units (1) and (2) comprise the nucleus of three “Demonstration” relationships.\nThe discursive analysis of a document normally includes three consecutive steps: 1) discursive segmentation; 2) detection of the discursive relations; 3) construction of the hierarchical rhetorical tree. Regarding the discursive segmentation, there are segmenters in several languages. However, each piece depends on sofisticated linguistic resources, which complicates the reproduction of the experiments in other languages.

Our method has the same computational complexity as the old method and offers an exact count instead of an approximation.\nWe propose an alternative. As before, store the frequencies of words and the frequencies of bigrams, but this time store two additional maps called too_far_left and too_far_right, of the form {word : list of offending indices of word}. The offending indices are those that are either too far to the left or too far to the right for approximation ( 1 ) to hold. All four of these structures are built during the construction of a bigram finder, and do not cripple performance when computing statistical measures since maps are queried in $O(1)$ time.\nAs an example of the contents of the new maps, in “Dogs are better than cats\", too_far_left[`dog'] = [0] for all windows. In “eight mice eat eight cheese sticks” with window 5, too_far_left[`eight'] = [0,3]. For ease of computation the indices stored in too_far_right are transformed before storage using: \n$$\\widehat{idx} = length - idx - 1 = g(idx)$$   (Eq. 6) \nwhere $length$ is the length of the small piece of text being analyzed. Then, too_far_right[`cats'] = [ $g(4)= idx$ ] = [ $0 = \\widehat{idx}$ ].\nNow, to compute the exact number of occurrences of a bigram we do the computation: \n$$freq(*, word) = (w-1)*wordfd[word] - \\sum \\limits _{i=1}^{N}(w-tfl[word][i] - 1)$$   (Eq. 7) \nwhere $w$ is the window size being searched for bigrams, $wfd$ is a frequency distribution of all words in the corpus, $tfl$ is the map too_far_left and $N$ is the number of occurrences of the $word$ in a position too far left.The computation of $freq(word, *)$ can now be performed in the same way by simply substituting $tfl$ with $tfr$ thanks to transformation $g$ , which reverses the indexing. \nWe show that an efficient and popular method for calculating bigram frequencies is unsuitable for bodies of short texts and offer a simple alternative.

        "evidence": "The ideological leanings of a person within the left-right political spectrum are often reflected by how one feels about different topics and by means of preferences among various choices on particular issues. For example, a left-leaning person would prefer nationalization and state control of public services (such as healthcare) where privatization would be often preferred by people that lean towards the right. Likewise, a left-leaning person would often be supportive of immigration and will often talk about immigration in a positive manner citing examples of benefits of immigration on a country's economy. A right-leaning person, on the other hand, will often have a negative opinion about immigration.\nMost of the existing works on political ideology detection from text have focused on utilizing bag-of-words and other syntactic features to capture variations in language use BIBREF0 , BIBREF1 , BIBREF2 . We propose an alternative mechanism for political ideology detection based on sentiment analysis. We posit that adherents of a political ideology generally have similar sentiment toward specific topics (for example, right wing followers are often positive towards free markets, lower tax rates, etc.) and thus, a political ideology can be represented by a characteristic sentiment distribution over different topics (Section SECREF3 ). This topic-specific sentiment representation of a political ideology can then be used for automatic ideology detection by comparing the topic-specific sentiments as expressed by the content in a document (news article, magazine article, collection of social media posts by a user, utterances in a conversation, etc.).\nIn order to validate our hypothesis, we consider exploiting the sentiment information towards topics from archives of political debates to build a model for identifying political orientation of speakers as one of right or left leaning, which corresponds to republicans and democrats respectively, within the context of US politics. This is inspired by our observation that the political leanings of debators are often expressed in debates by way of speakers' sentiments towards particular topics. Parliamentary or Senate debates often bring the ideological differences to the centre stage, though somewhat indirectly. Heated debates in such forums tend to focus on the choices proposed by the executive that are in sharp conflict with the preference structure of the opposition members. Due to this inherent tendency of parliamentary debates to focus on topics of disagreement, the sentiments exposited in debates hold valuable cues to identify the political orientation of the participants.\nWe develop a simple classification model that uses a topic-specific sentiment summarization for republican and democrat speeches separately. Initial results of experiments conducted using a widely used dataset of US Congress debates BIBREF3 are encouraging and show that this simple model compares well with classification models that employ state-of-the-art distributional text representations (Section SECREF4 ).\nWe propose an alternative mechanism for political ideology detection based on sentiment analysis.",

Convolutional neural networks (CNNs) and recurrent neural networks (RNNs) especially Long Short-term Memory Network (LSTM), are used wildly in natural language processing tasks. With increasing datas, these two methods can reach considerable performance by requiring only limited domain knowledge and easy to be finetuned to specific applications at the same time.\nCNNs, which have the ability of capturing local correlations of spatial or temporal structures, have achieved excellent performance in computer vision and NLP tasks. And recently the emerge of some new techniques, such as Inception module BIBREF8 , Batchnorm BIBREF9 and Residual Network BIBREF3 have also made the performance even better. For sentence modeling, CNNs perform excellently in extracting n-gram features at different positions of a sentence through convolutional filters.\nRNNs, with the ability of handling sequences of any length and capturing long-term dependencies, , have also achieved remarkable results in sentence or document modeling tasks. LSTMs BIBREF10 were designed for better remembering and memory accesses, which can also avoid the problem of gradient exploding or vanishing in the standard RNN. Be capable of incorporating context on both sides of every position in the input sequence, BLSTMs introduced in BIBREF11 , BIBREF12 have reported to achieve great performance in Handwriting Recognition BIBREF13 , and Machine Translation BIBREF14 tasks.\nGenerative adversarial networks (GANs) BIBREF15 are a class of generative models for learning how to produce images. Basically, GANs consist of a generator G and a discriminator D, which are trained based on game theory. G maps a input noise vector to an output image, while D takes in an image then outputs a prediction whether the input image is a sample generated by G. Recently, applications of GANs have shown that they can generate promising results BIBREF16 , BIBREF17 . Several recent papers have also extended GANs to the semi-supervised context BIBREF18 , BIBREF19 by simply increasing the dimension of the classifier output from INLINEFORM0 to INLINEFORM1 , which the samples of the extra class are generated by G.\nIn this paper, We proposed an end-to-end architecture named AC-BLSTM by combining the ACNN with the BLSTM for sentences and documents modeling. In order to make the model deeper, instead of using the normal convolution, we apply the technique proposed in BIBREF8 which employs a INLINEFORM0 convolution followed by a INLINEFORM1 convolution by spatial factorizing the INLINEFORM2 convolution. And we use the pretrained word2vec vectors BIBREF20 as the ACNN input, which were trained on 100 billion words of Google News to learn the higher-level representations of n-grams. The outputs of the ACNN are organized as the sequence window feature to feed into the multi-layer BLSTM. So our model does not rely on any other extra domain specific knowledge and complex preprocess, e.g. word segmentation, part of speech tagging and so on. We evaluate AC-BLSTM on sentence-level and document-level tasks including sentiment analysis, question type classification, and subjectivity classification. Experimental results demonstrate the effectiveness of our approach compared with other state-of-the-art methods. Further more, inspired by the ideas of extending GANs to the semi-supervised learning context by BIBREF18 , BIBREF19 , we propose a semi-supervised learning framework for text classification which further improve the performance of AC-BLSTM.\nThe rest of the paper is organized as follows. Section 2 presents a brief review of related work. Section 3 discusses the architecture of our AC-BLSTM and our semi-supervised framework. Section 4 presents the experiments result with comparison analysis.

        "answer": "bilingual dictionary induction, monolingual and cross-lingual word similarity, and cross-lingual hypernym discovery",
        "evidence": "Our experimental results show that the proposed additional transformation does not only benefit cross-lingual evaluation tasks, but, perhaps surprisingly, also monolingual ones. In particular, we perform an extensive set of experiments on standard benchmarks for bilingual dictionary induction and monolingual and cross-lingual word similarity, as well as on an extrinsic task: cross-lingual hypernym discovery.\nTables 2 and 3 show the monolingual and cross-lingual word similarity results, respectively. For both the monolingual and cross-lingual settings, we can notice that our models generally outperform the corresponding baselines. Moreover, in cases where no improvement is obtained, the differences tend to be minimal, with the exception of RG-65, but this is a very small test set for which larger variations can thus be expected. In contrast, there are a few cases where substantial gains were obtained by using our model. This is most notable for English WordSim and SimLex in the monolingual setting.\nAs can be seen in Table 1 , our refinement method consistently improves over the baselines (i.e., VecMap and MUSE) on all language pairs and metrics. The higher scores indicate that the two monolingual embedding spaces become more tightly integrated because of our additional transformation. It is worth highlighting here the case of English-Finnish, where the gains obtained in $P@5$ and $P@10$ are considerable. This might indicate that our approach is especially useful for morphologically richer languages such as Finnish, where the limitations of the previous bilingual mappings are most apparent.\nThe results listed in Table 4 indicate several trends. First and foremost, in terms of model-wise comparisons, we observe that our proposed alterations of both VecMap and MUSE improve their quality in a consistent manner, across most metrics and data configurations. In Italian our proposed model shows an improvement across all configurations. However, in Spanish VecMap emerges as a highly competitive baseline, with our model only showing an improved performance when training data in this language abounds (in this specific case there is an increase from 17.2 to 19.5 points in the MRR metric). This suggests that the fact that the monolingual spaces are closer in our model is clearly beneficial when hybrid training data is given as input, opening up avenues for future work on weakly-supervised learning. Concerning the other baseline, MUSE, the contribution of our proposed model is consistent for both languages, again becoming more apparent in the Italian split and in a fully cross-lingual setting, where the improvement in MRR is almost 3 points (from 10.6 to 13.3). Finally, it is noteworthy that even in the setting where no training data from the target language is leveraged, all the systems based on cross-lingual embeddings outperform the best unsupervised baseline, which is a very encouraging result with regards to solving tasks for languages on which training data is not easily accessible or not directly available.\nIn particular, we perform an extensive set of experiments on standard benchmarks for bilingual dictionary induction and monolingual and cross-lingual word similarity, as well as on an extrinsic task: cross-lingual hypernym discovery.\nFor both the monolingual and cross-lingual settings, we can notice that our models generally outperform the corresponding baselines. \nAs can be seen in Table 1 , our refinement method consistently improves over the baselines (i.e., VecMap and MUSE) on all language pairs and metrics.\nFirst and foremost, in terms of model-wise comparisons, we observe that our proposed alterations of both VecMap and MUSE improve their quality in a consistent manner, across most metrics and data configurations.",

        "question": "What do the authors combine to showcase the algorithmic methodology?",
        "answer": "Combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nTo do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods.",

We have shown that transformer-based encoders together with GRU models provide the best performance for question representation. Notably, we demonstrated that using pre-trained text representations provide consistent performance improvements across several hyper-parameter configurations. We have also shown that using an object detector fine-tuned with external data provides large improvements in accuracy. Our experiments have demonstrated that even simple fusion strategies can achieve performance on par with the state-of-the-art. Moreover, we have shown that attention mechanisms are paramount for learning top performing networks, once they allow producing question-aware image representations that are capable of encoding spatial relations. It became clear that Top-Down is the preferred attention method, given its results with ReLU activation. It is is now clear that some configurations used in some architectures (e.g., additional RNN layers) are actually irrelevant and can be removed altogether without harming accuracy.

From all tweets in our stream from 2016 or 2017, we extract those tweets that have at least two @-mentions and all of the @-mentions have been seen at least five times in the background corpus. Based on the resulting 1.8 million lists of about 169,000 distinct user ids, we compute a topic model with INLINEFORM0 topics using Latent Dirichlet Allocation BIBREF3 .

Sequence LSTM is used to identify all the entities first and then Tree LSTM is used to find the relation between all pairs of entities.\n(2) Tagging BIBREF5: This is a neural sequence tagging model which jointly extracts the entities and relations using an LSTM encoder and an LSTM decoder. They used a Cartesian product of entity tags and relation tags to encode the entity and relation information together. This model does not work when tuples have overlapping entities.\n(3) CopyR BIBREF6: This model uses an encoder-decoder approach for joint extraction of entities and relations. It copies only the last token of an entity from the source sentence. Their best performing multi-decoder model is trained with a fixed number of decoders where each decoder extracts one tuple.\n(4) HRL BIBREF11: This model uses a reinforcement learning (RL) algorithm with two levels of hierarchy for tuple extraction. A high-level RL finds the relation and a low-level RL identifies the two entities using a sequence tagging approach. This sequence tagging approach cannot always ensure extraction of exactly two entities.\n(5) GraphR BIBREF14: This model considers each token in a sentence as a node in a graph, and edges connecting the nodes as relations between them. They use graph convolution network (GCN) to predict the relations of every edge and then filter out some of the relations.\n(6) N-gram Attention BIBREF9: This model uses an encoder-decoder approach with N-gram attention mechanism for knowledge-base completion using distantly supervised data. The encoder uses the source tokens as its vocabulary and the decoder uses the entire Wikidata BIBREF15 entity IDs and relation IDs as its vocabulary. The encoder takes the source sentence as input and the decoder outputs the two entity IDs and relation ID for every tuple. During training, it uses the mapping of entity names and their Wikidata IDs of the entire Wikidata for proper alignment. Our task of extracting relation tuples with the raw entity names from a sentence is more challenging since entity names are not of fixed length. Our more generic approach is also helpful for extracting new entities which are not present in the existing knowledge bases such as Wikidata.

        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nBut high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world’s estimated 7,000 languages (Besacier et al., 2014).",

Table TABREF8 gives data statistics. Different from the current cloze-style datasets for English reading comprehension, such as CBT, Daily Mail and CNN BIBREF0 , the three Chinese datasets do not provide candidate answers.

        "question": "Why is MobileNet performing the best across the 3 models in Figure 2?",
        "answer": "We first want to mention that since Figure 2 is not directly relevant to the main purpose of the paper, we have moved that figure to Appendix B and changed the figure to avoid misunderstanding. As mentioned in the paper, calculating the hardness degree of samples does not require the true label of samples. Nevertheless, since we had access to the true labels of CIFAR10 and CIFAR100 test samples, we depict Figure 2 (Figure 6) to give more intuition about the hardness degree of samples. To depict this figure, we first calculate the hardness degree of CIFAR10 and CIFAR100 test samples and then partition them into ten groups based on their hardness degree. Notably, the number of samples in each group is different. Afterward, we calculate what percentage of samples in each group is classified incorrectly. The figure demonstrates that the misclassification rate is increased by increasing the hardness degree of samples. In other words, there is a strong positive correlation between the hardness degree of samples and the misclassification rate.\nAlthough the curve of MobileNet is upper than two other classifiers in Figure 2, this does not mean that the MobileNet is the best classifier across the three models. The number of samples in each range of hardness degree is different between models. Given Figure 1, CIFAR10 and CIFAR100 test samples are relatively harder for MobileNet classifiers than two other classifiers. Since models misclassify harder samples with higher probability, and since the number of harder samples is more for the MobileNet classifier, this classifier has the worst performance across models. Figure 6 indicates the percentage of samples in each hardness degree range by a green curve. We have added an example to Appendix B to clarify Figure 6.",
        "evidence": "To assess the relationship between the hardness degree of samples and the misclassification rate, we compute the hardness degree of CIFAR10 and CIFAR100 test samples and then partition them into ten groups based on their hardness degree. It is important to note that the number of samples in each group is different. Afterward, we calculate what percentage of samples in each group is classified incorrectly. Figure 6 demonstrates that the misclassification rate is increased by increasing the hardness degree of samples. In other words, there is a strong positive correlation between the hardness degree of samples and the misclassification rate. The figure indicates the percentage of samples in each hardness degree range by a green curve. For example, the hardness degree of 40.65% of CIFAR10 test samples (4065 samples) is in the range [0,9] for MobileNet classifier, from which 99.88% is classified correctly, or the hardness degree of 7.4% of CIFAR10 test samples (740 samples) is in the range [90,99] for MobileNet classifier, from which 55.27% is classified correctly. More than 99% and 95% of samples being learned in the first 30 epochs (hardness degree < 30) are correctly classified in CIFAR10 and CIFAR100 test samples, respectively. On the other side, less than 55% and 36% of samples being learned in the last 10 epochs (hardness degree ≥ 90) are correctly classified in CIFAR10 and CIFAR100 test samples, respectively.",

        "evidence": "In the mathematical area of graph theory, a clique is a subset of vertices of an undirected graph such that every two distinct vertices in the clique are adjacent. That is, a clique of a graph  G is an induced subgraph of  G that is complete. Cliques are one of the basic concepts of graph theory and are used in many other mathematical problems and constructions on graphs. Cliques have also been studied in computer science: the task of finding whether there is a clique of a given size in a graph (the clique problem) is NP-complete, but despite this hardness result, many algorithms for finding cliques have been studied.\n\nAlthough the study of complete subgraphs goes back at least to the graph-theoretic reformulation of Ramsey theory by Erdős & Szekeres (1935), the term clique comes from Luce & Perry (1949), who used complete subgraphs in social networks to model cliques of people; that is, groups of people all of whom know each other. Cliques have many other applications in the sciences and particularly in bioinformatics.",

        "question": "How do I train my dog to not pee in the house?",
        "evidence": "",
        "answer": "Puppies do best on a regular schedule. The schedule teaches them that there are times to eat, times to play and times to do their business. Typically, a puppy can control their bladder one hour for every month of age. So if your puppy is 2 months old, they can hold it for about two hours. Don't go longer than this between bathroom breaks or they’re likely to have an accident.\n\nTake your puppy outside frequently—at least every two hours—and immediately after they wake up, during and after playing, and after eating or drinking.\n\nPick a bathroom spot outside, and always take your puppy (on a leash) to that spot. While your puppy is relieving themselves, use a specific word or phrase that you can eventually use before they go to remind them what to do. Take them out for a longer walk or some playtime only after they have eliminated.\n\nReward your puppy every time they eliminate outdoors. Praise or give treats—but remember to do so immediately after they’ve finished, not after they come back inside. This step is vital, because rewarding your dog for going outdoors is the only way to teach what's expected of them. Before rewarding, be sure they’re finished. Puppies are easily distracted and if you praise too soon, they may forget to finish until they’re back in the house.\n\nPut your puppy on a regular feeding schedule. What goes into a puppy on a schedule comes out of a puppy on a schedule. Depending on their age, puppies may need to be fed two or three times a day. Feeding your puppy at the same times each day will make it more likely that they'll eliminate at consistent times as well, making house training easier for both of you.\n\nPick up your puppy's water dish about two and a half hours before bedtime to reduce the likelihood that they'll need to relieve themselves during the night. Most puppies can sleep for approximately seven hours without needing a bathroom break. If your puppy does wake you up in the night, don't make a big deal of it; otherwise, they will think it is time to play and won't want to go back to sleep. Turn on as few lights as possible, don't talk to or play with your puppy, take them out to the spot where they relieve themselves and then return them to bed.",

They are capable of \"stinging\" humans, therefore live ones should be handled carefully or not at all.\n\nDescription\nThe size of the shell varies between 40 mm and 115 mm. The shell of Conus Episcopatus is elongated and has a high spire, which means that it has a tall apex. The shell is relatively thick and heavy, with a glossy surface and a series of raised ridges or ribs that run along its length. The overall shape of the shell is conical, with a pointed apex and a wider base.\n\nThe coloration of the shell can vary widely, but it basically has a base color of white or cream, with a series of darker or lighter bands, blotches, or spots that form complex patterns. The patterns can be quite intricate and unique, which is one reason why cone snails are prized by collectors.\n\nLike all cone snails, Conus Episcopatus is venomous and uses its venom to immobilize and kill its prey. Venom is delivered through a harpoon-like structure called a radula tooth located on the proboscis of the snail. The venom of some species of cone snail can be highly toxic and dangerous to humans, and care must be taken when handling them.",

For example, we may read that exercise improves health, and thus decide to spend more time at the gym; or that larger cars cause more pollution, and thus decide to buy a smaller car to be environmentally sensitive. These skills require understanding the underlying qualitative relationships, and being able to apply them in specific contexts.\nTo promote research in this direction, we present the first open-domain dataset of qualitative relationship questions, called QuaRTz (“Qualitative Relationship Test set”). Unlike earlier work in qualitative reasoning, e.g., BIBREF0, the dataset is not restricted to a small, fixed set of relationships. Each question $Q_i$ (2-way multiple choice) is grounded in a particular situation, and is paired with a sentence $K_i$ expressing the general qualitative knowledge needed to answer it. $Q_i$ and $K_i$ are also annotated with the properties being compared (Figure FIGREF1). The property annotations serve as supervision for a potential semantic parsing based approach. The overall task is to answer the $Q_i$ given the corpus $K = \\lbrace K_i\\rbrace $.\nWe test several state-of-the-art (BERT-based) models and find that they are still substantially (20%) below human performance. Our contributions are thus (1) the dataset, containing 3864 richly annotated questions plus a background corpus of 400 qualitative knowledge sentences; and (2) an analysis of the dataset, performance of BERT-based models, and a catalog of the challenges it poses, pointing the way towards solutions.\nTo promote research in this direction, we present the first open-domain dataset of qualitative relationship questions, called QUARTZ (“Qualitative Relationship Test set”)1 .",

        "evidence": "Rumi's poetry is often divided into various categories: the quatrains (rubayāt) and odes (ghazal) of the Divan, the six books of the Masnavi. The prose works are divided into The Discourses, The Letters, and the Seven Sermons.\n\nPoetic works\n\nMaṭnawīye Ma'nawī, Mevlâna Museum, Konya, Turkey\nRumi's best-known work is the Maṭnawīye Ma'nawī (Spiritual Couplets; مثنوی معنوی). The six-volume poem holds a distinguished place within the rich tradition of Persian Sufi literature, and has been commonly called \"the Quran in Persian\". Many commentators have regarded it as the greatest mystical poem in world literature. It contains approximately 27,000 lines, each consisting of a couplet with an internal rhyme. While the mathnawi genre of poetry may use a variety of different metres, after Rumi composed his poem, the metre he used became the mathnawi metre par excellence. The first recorded use of this metre for a mathnawi poem took place at the Nizari Ismaili fortress of Girdkuh between 1131–1139. It likely set the stage for later poetry in this style by mystics such as Attar and Rumi.\nRumi's other major work is the Dīwān-e Kabīr (Great Work) or Dīwān-e Shams-e Tabrīzī (The Works of Shams of Tabriz; دیوان شمس تبریزی), named in honour of Rumi's master Shams. Besides approximately 35000 Persian couplets and 2000 Persian quatrains, the Divan contains 90 Ghazals and 19 quatrains in Arabic, a couple of dozen or so couplets in Turkish (mainly macaronic poems of mixed Persian and Turkish) and 14 couplets in Greek (all of them in three macaronic poems of Greek-Persian).\nProse works\nFihi Ma Fihi (In It What's in It, Persian: فیه ما فیه) provides a record of seventy-one talks and lectures given by Rumi on various occasions to his disciples. It was compiled from the notes of his various disciples, so Rumi did not author the work directly. An English translation from the Persian was first published by A.J. Arberry as Discourses of Rumi (New York: Samuel Weiser, 1972), and a translation of the second book by Wheeler Thackston, Sign of the Unseen (Putney, VT: Threshold Books, 1994). The style of the Fihi ma fihi is colloquial and meant for middle-class men and women, and lack the sophisticated wordplay.\nMajāles-e Sab'a (Seven Sessions, Persian: مجالس سبعه) contains seven Persian sermons (as the name implies) or lectures given in seven different assemblies. The sermons themselves give a commentary on the deeper meaning of Qur'an and Hadith. The sermons also include quotations from poems of Sana'i, 'Attar, and other poets, including Rumi himself. As Aflakī relates, after Shams-e Tabrīzī, Rumi gave sermons at the request of notables, especially Salāh al-Dīn Zarkūb. The style of Persian is rather simple, but quotation of Arabic and knowledge of history and the Hadith show Rumi's knowledge in the Islamic sciences. His style is typical of the genre of lectures given by Sufis and spiritual teachers.\nMakatib (The Letters, Persian: مکاتیب) or Maktubat (مکتوبات) is the collection of letters written in Persian by Rumi to his disciples, family members, and men of state and of influence. The letters testify that Rumi kept very busy helping family members and administering a community of disciples that had grown up around them. Unlike the Persian style of the previous two mentioned works (which are lectures and sermons), the letters are consciously sophisticated and epistolary in style, which is in conformity with the expectations of correspondence directed to nobles, statesmen and kings.",

Armstrong modified this guitar with a Bill Lawrence humbucking pickup on the bridge position. After sustaining damage from mud during their performance in Woodstock '94, the bridge pickup was replaced with a Seymour Duncan JB. Blue was used on the recording of every Green Day album until Warning, and during live performances of Green Day's early work, such as their songs from Dookie. Armstrong also used a Fender Stratocaster from the Fender Custom Shop while recording Nimrod.\nRandy Bachman (born 1943), a founding member of both The Guess Who and Bachman–Turner Overdrive (BTO) who recently fronted the project \"Randy Bachman's Jazz Thing.\" After a visit to a chiropractor, Bachman was persuaded to switch from a Gibson Les Paul to a lighter Stratocaster. He modified the pickups on his first Strat, putting a Gibson pickup at the neck and a Telecaster pickup at the bridge, while leaving the Stratocaster pickup in the middle. Randy favored Stratocasters and custom Strat-style guitars throughout his years with BTO. Though his bands are mostly known for their simplistic rock-radio anthems, Bachman's soloing often revealed complex melodies and jazz-inflected phrasing. Among his Stratocasters used are a '63 standard and a '71 four-bolt hardtail. He has listed guitar influences as varied as Lenny Breau, Leslie West, Wes Montgomery and Hank Marvin.\n\nJeff Beck in Amsterdam, 1979.\nJeff Beck (born 1944-2023) - a Grammy award-winning rock guitarist, Beck was known for playing for various bands such as the Yardbirds and his own group The Jeff Beck Group. Beck primarily played a Stratocaster and also has a signature Strat. He was noted for his innovative use of the Stratocaster's vibrato system. Up to 1975 Beck had been, primarily, a Les Paul player. In an interview with Jas Obrecht about switching to the Stratocaster, Beck stated, \"With a Les Paul you just wind up sounding like someone else. With the Strat I finally sound like me.\"\nAdrian Belew (born 1949), is an American guitarist, singer, songwriter, multi-instrumentalist and record producer. He is perhaps best known for his work as a member of the progressive rock group King Crimson. He has also worked extensively as a session and touring musician, most famously with Talking Heads, David Bowie, Frank Zappa, and Nine Inch Nails. During much of his career, Belew made extensive use of a weathered-looking Stratocaster, later memorialized in song as \"The Battered Strat.\" This guitar was relic'ed by Seymour Duncan.\n\nRitchie Blackmore in 1977.\nRitchie Blackmore (born 1945), a founding member of both Deep Purple and Rainbow, and currently a member of the band Blackmore's Night. After starting his career using various Höfner and Gibson guitars, Blackmore switched to a Stratocaster in the late 1960s after seeing Jimi Hendrix perform with one. Blackmore's Stratocasters are modified; the middle pickup is lowered and not used (sometimes disconnected completely) and his Stratocaster fingerboards are all scalloped from the 10th fret up. Through the early/mid 1970s Blackmore was notorious for onstage abuse of his guitars, sometimes destroying them completely. By the late 1970s the guitarist had found a Stratocaster model he was content with and it remained his main stage and studio guitar up until it had to be refretted.\nTommy Bolin (1951-1976), a versatile guitarist who is noted for his influence in genres ranging from acoustic blues to hard rock and jazz fusion. He was the lead guitarist for Zephyr, James Gang and Deep Purple. He also had a successful solo career, and collaborated with artists like Billy Cobham, Alphonse Mouzon and The Good Rats.

Blackie, a composite of three different guitars, went into service in 1970 and was regularly played until its retirement in 1985. It was sold at charity auction for $959,500 in 2004. In 1988, Fender introduced the Eric Clapton Stratocaster, the first model in their Signature series. Clapton has been a long-standing client of the Fender Custom Shop.[citation needed]\nKurt Cobain (1967–1994), lead singer and guitarist of grunge band Nirvana, used Fender Stratocasters throughout his career, using the guitar in the music video for \"Smells Like Teen Spirit\" and in the band's famous performance at the 1992 Reading Festival. Cobain's most well-known Stratocaster has a sticker on the body with the text \"VANDALISM: BEAUTIFUL AS A ROCK IN A COP'S FACE.\"\n\nEric Clapton in a Switzerland concert on June 19, 1977.\nRy Cooder (born 1947), a guitarist, singer and composer who is well known for his interest in American folk music, his collaborations with other notable musicians, and his work on many film soundtracks. Cooder's bottleneck slide guitar playing, heard on such works as the soundtrack to the 1984 film Paris, Texas, influenced other guitarists such as Bonnie Raitt and Chris Rea and contributed to the popularity of the Stratocaster as a slide guitar. He uses a '60s Stratocaster for such playing.\nRobert Cray (born 1953), a long-time blues guitarist and singer, Cray plays a '64 Strat and had his own Signature model made in 1990. The signature model, manufactured by the Fender Custom Shop, combines aspects of Cray's '59 Strat and the '64, omits the standard Stratocaster whammy bar, and includes custom pickups.\nDick Dale (1937–2019), considered a pioneer of surf rock, was one of the first owners of a Stratocaster; his was given to him personally by Leo Fender in 1955. He has been revolutionary in experimenting with the sound of the guitar by using heavy reverb and a unique fast-picking style as heard on \"Misirlou\".\nThe Edge (born 1961), lead guitarist of U2, known for his percussive, melodic playing and use of delay, has used the Stratocaster as one of his main guitars throughout his career.\nF–J\n\nJohn Frusciante in 2006.\nJohn Frusciante (born 1970), the current guitarist of Red Hot Chili Peppers, Frusciante used many pre-70s Strats, with the most notable being his worn 1962 Stratocaster. Frusciante used Stratocasters in every Red Hot Chili Peppers album he was involved with, including Mother's Milk, Blood Sugar Sex Magik,and Californication.\n\nRory Gallagher in 1987\nRory Gallagher (1948–1995), an Irish blues rock guitarist, often credited as one of the most influential rock and blues guitarists of all time. Gallagher is well known for his worn 1961 sunburst Stratocaster. He described his battered Stratocaster as \"a part of my psychic makeup\". When asked about its importance, Gallagher said, \"B.B. King has owned over 100 Lucilles, but I only own one Strat, and it hasn't got a name.\" Gallagher's Stratocaster has also been reproduced by the Fender Custom shop, to the exact specs of the original one.\nLowell George (1945–1979), primary guitarist and singer of Little Feat. Lowell was proficient on slide guitar employing his trademark tone which he achieved through use of compression and open tunings helping to define his soulful sound as well as giving him the means to play his extended melodic lines. Additionally, he used to swap the bridge pickups of his Stratocasters for Telecaster bridge pickups.\n\nDavid Gilmour in 2006.\nDavid Gilmour (born 1946), as a solo artist and guitar player for Pink Floyd, Gilmour is credited for his unique, blues-based compositional approach and expressive soloing. Author Tony Bacon stated \"his solo on 'Comfortably Numb' remains for many a definitive Strat moment.\" Gilmour's guitar of choice is a custom modified Fender Stratocaster. He is the owner of Strat #0001, which was manufactured in 1954 but was not the first Stratocaster made since Fender does not use sequential serial numbers. Gilmour is considered to be one of the more influential Stratocaster players since the instrument's invention. David's signature black Stratocaster, used frequently in 1970s concerts and on the blockbuster albums The Dark Side of the Moon, Wish You Were Here, Animals and The Wall, is featured in a recent book by his long-time guitar tech Phil Taylor, titled Pink Floyd, The Black Strat—A History of David Gilmour's Black Stratocaster. The \"Black Strat\" was retired in the 1980s in favour of a Candy Apple Red American Vintage Stratocaster fitted with EMG noiseless single-coil pickups as seen on the Delicate Sound of Thunder and Pulse tours. The Black Strat was briefly used on the documentary Classic Albums: Dark Side of the Moon before being put on display at the Hard Rock Cafe in Miami, Florida. It was finally brought out of retirement by David in 2005 and fitted with a '83 Fender Stratocaster neck for the Pink Floyd reunion at the Live 8 concert. David subsequently used it again for his \"On An Island\" album and tour in 2006 and when he played \"Comfortably Numb\" with Roger Waters on his tour of \"The Wall\" on May 12, 2011, in London and also played most of the leads on the final Pink Floyd album The Endless River and his 2015 solo album Rattle That Lock and its tour.\n\nBuddy Guy in 1992.\nBuddy Guy (born 1936), an American blues guitarist and singer, Guy is well known for playing the Stratocaster throughout his long career. He is also known for his wild showmanship; Jimi Hendrix and Stevie Ray Vaughan both pointed to Guy as an influence on both their playing and their stage shows. Fender has issued several different variations of a Buddy Guy Signature Stratocaster since the early 1990s; the guitars generally have gold Lace Sensor pickups and modified circuitry.\nAlbert Hammond Jr. (born 1980), guitarist for The Strokes, uses a white Fender Stratocaster as his main guitar for recording and live use. Hammond bought the guitar in 1999 for $400, and used it to record albums such as Is This It and Room on Fire. In 2018, Fender released a signature model of Hammond's guitar, featuring a larger headstock and a modified pickup wiring scheme.\nGeorge Harrison (1943–2001), lead guitarist for the Beatles. Harrison and John Lennon obtained matching Sonic Blue Stratocasters in 1965. Unlike Lennon, Harrison employed his Stratocaster more often, using it as his main guitar during the recording sessions for Rubber Soul, Sgt. Pepper's Lonely Hearts Club Band, and the White Album. In 1967, Harrison hand-painted his Stratocaster with a psychedelic paint job, using Day-Glo paint on the body and his wife Pattie Boyd's nail polish on the headstock. The guitar's nickname, \"Rocky\", is painted on the headstock. Harrison can be seen playing Rocky in the Magical Mystery Tour film as well as The Concert for Bangla Desh.\n\nJimi Hendrix in 1967.\nJimi Hendrix (1942–1970), known for developing blues in a modern context, Hendrix's main stage guitar through most of his short career was a Fender Stratocaster. Although Hendrix played left-handed, he played a conventional right-handed Stratocaster flipped upside down, because he preferred to have the control knobs in the top position. Hendrix was responsible for a large increase in the Stratocaster's popularity during his career. In reference to his famed on-stage Stratocaster burning on the Monterey Pop Festival, Hendrix is quoted as saying, \"The time I burned my guitar it was like a sacrifice. You sacrifice the things you love. I love my guitar.\" In 1990, the white Stratocaster used by Hendrix at the 1969 Woodstock Festival sold in a Sotheby's auction for $270,000, a record price at the time. In 1997 Fender produced a limited edition Hendrix tribute model Stratocaster.\nBuddy Holly (1936–1959), identified as \"the first Strat hero.\" A statue of Holly in his home town of Lubbock, Texas, portrays him playing his Stratocaster, and the guitar is also engraved on his tombstone. Although the initial release of the Stratocaster came in 1954, the guitar did not begin to achieve popularity until Holly appeared on The Ed Sullivan Show in 1957 playing a maple-neck Strat. Holly was also pictured on the cover of The Crickets' 1957 album The \"Chirping\" Crickets with a sunburst Stratocaster, inspiring The Shadows' Hank Marvin to adopt the guitar.\nErnie Isley (born 1952), member of the American musical ensemble The Isley Brothers has developed three custom Zeal Stratocasters from Fender Custom Shop, using his personal design.\nEric Johnson (born 1954), a Grammy Award-winning guitarist from Austin, Texas, Johnson has played Stratocasters regularly during his career and has played many different types of music.

He used a 1959 model with a black refinish and tortoise pickguard for most recordings and live performances at that time, and also a 1973 model which he used when writing the hit \"Sweet Home Alabama\".\nMark Knopfler (born 1949), known for his work with British rock band Dire Straits. Knopfler is known for his very particular and unique fingerstyle playing. The song \"Sultans of Swing\", from Dire Straits' debut album in 1978, was a huge hit that showed the characteristic tone and technique displayed on Knopfler's red Stratocaster. He used the Fender Stratocaster throughout his entire career, as a member of Dire Straits and his solo career. Fender now produces his Signature Stratocaster.\nGreg Koch (born 1966), known for his incendiary guitar work. Koch was a Fender clinician and ambassador. He played the Stratocaster for many years and even recorded an album called Strat's Got Your Tongue.

Kulick stated on his personal website that he used a Fender Power Stratocaster, a model with a humbucking pickup in place of the single-coil bridge pickup, to add a harmony solo line to his song, \"What Love's All About.\" Kulick used a 1989 yellow Fender Strat Plus, during the recording of the 1992 Kiss Revenge album, including for the hit single, \"God Gave Rock 'n Roll to You II.\" Revenge reached the Top 20 in several countries.\nMichael Landau (born 1958), friend of Steve Lukather and prolific session guitarist of the 1980s, has used many Stratocasters in his career and is working with Fender as of 2016 to create a Michael Landau Signature Stratocaster.\nJohn Lennon (1940–1980), the Beatles' rhythm guitarist, acquired matching Stratocasters with bandmate George Harrison during the 1965 sessions for Help!. However, Lennon rarely used his Stratocaster, which was notably played on \"Nowhere Man\" and during the Sgt. Pepper sessions. A different Strat was used on the Imagine album. John Lennon acquired a candy apple red \"Strat\" with 22 carat gold electroplated brass hardware around 1980. A photo of him playing this guitar in bed one morning in late 1980, shortly before his death, was used an inner sleeve of the album The John Lennon Collection.\nAlex Lifeson (born 1953), the guitarist for Rush since 1968, first recorded with a black Stratocaster on the Rush 1977 album A Farewell to Kings. In 1979, he modified the '77 Strat with a '57 classic humbucker, a Floyd Rose tremolo unit (first ever made), a Gibson toggle switch on the lower bout, and rewired with master volume/tone. He used that same guitar for the leads and direct recording for 1979's \"Permanent Waves.\" In late 1980, Alex Lifeson acquired two more Strats in red and white, modifying them exactly the same as the former.\nYngwie Malmsteen (born 1963), known for his work in the neo-classical metal genre.

He is known for playing Stratocasters with scalloped fretboards.\nHank Marvin (born 1941), the lead guitarist of The Shadows, Marvin is reputed to be the owner of the first Fender Stratocaster in the UK (given to him by Cliff Richard). The guitar was finished in a shade of Fiesta Red, sometimes referred to as 'Salmon Pink'. This guitar, with its tremolo arm, contributed to the Shadows' distinctive sound. Guitarists such as David Gilmour and Mark Knopfler credit Marvin and The Shadows, who had \"the first Strat that came to England\", with influencing their own decisions to buy Stratocasters.\nJohn Mayer (born 1977), a Grammy Award-winning singer/songwriter, has played Stratocasters throughout his career and has had a Fender Artist Series Stratocaster made in both standard and limited edition form. Mayer's use of the Stratocaster in a wide range of musical genres is noted as a testament to the guitar's versatility. After tensions with Fender, he partnered with PRS Guitars to develop the PRS Silver Sky, a guitar heavily based on the Fender Stratocaster.\nMike Oldfield (born 1953), a British guitarist who plays a wide range of guitars and instruments. His \"Salmon-pink\" strat, bought at the time of his hit Moonlight Shadow, is his favorite guitar.\nQ–Z\n\nStevie Ray Vaughan performing in 1983\nTrevor Rabin (born 1954), a South African (now has American citizenship) rock guitarist and film score composer.

        "evidence": "The proliferation of the online social media has lately resulted in the democratization of online content sharing. Among other media, Twitter is very popular for research and application purposes due to its scale, representativeness and ease of public access to its content. However, tweets, that are short messages of up to 140 characters, pose several challenges to traditional Natural Language Processing (NLP) systems due to the creative use of characters and punctuation symbols, abbreviations ans slung language.\nNamed Entity Recognition (NER) is a fundamental step for most of the information extraction pipelines. Importantly, the terse and difficult text style of tweets presents serious challenges to NER systems, which are usually trained using more formal text sources such as newswire articles or Wikipedia entries that follow particular morpho-syntactic rules. As a result, off-the-self tools trained on such data perform poorly BIBREF0 . The problem becomes more intense as the number of entities to be identified increases, moving from the traditional setting of very few entities (persons, organization, time, location) to problems with more. Furthermore, most of the resources (e.g., software tools) and benchmarks for NER are for text written in English. As the multilingual content online increases, and English may not be anymore the lingua franca of the Web. Therefore, having resources and benchmarks in other languages is crucial for enabling information access worldwide.\nIn this paper, we propose a new benchmark for the problem of NER for tweets written in French. The tweets were collected using the publicly available Twitter API and annotated with 13 types of entities. The annotators were native speakers of French and had previous experience in the task of NER. Overall, the generated datasets consists of INLINEFORM0 tweets, split in training and test parts.\nThe paper is organized in two parts. In the first, we discuss the data preparation steps (collection, annotation) and we describe the proposed dataset. The dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated. Following, the second part of the paper presents an overview of baseline systems and the approaches employed by the systems that participated. We conclude with a discussion of the performance of Twitter NER systems and remarks for future work.\nThe dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated.",

Without a strong planetary defense and no time to prepare, Gaunt decided to save what soldiers he could for the imperium instead of fighting.  As chaos began attacking the planet, Gaunt organized the emergency launch of available Tanith troopers.  When all was complete, only a single strength regiment was able to get off the planet.  Tanith itself was destroyed by  the forces of Chaos from orbit and Trooper Larkin, a sniper in the regiment, dubbed the regiment 'ghosts'.

The gardens are inspired by the 17th century bastide, or Provençal manor, which stands on the site. They are private but open to the public, and are classified by the French Ministry of Culture among the Remarkable Gardens of France.\n\nHistory\nThe Chateau is built on the site of an ancient Roman villa, some of whose stones today decorate the garden. The building is decorated with the coat of arms of Jean de Joanis, the secretary of the King Louis III of Naples. The estate was occupied by the Arnaud family, who kept it until the 17th century. In 1754, the estate was given the status of a fief. The house and estate fell into ruins during the 19th century. It was purchased in 1977 by Jean-Louis Chancel. Between 1979 and 1999, he planted 186 hectares of vines. He also commissioned the architect Jean-Jacques Pichoux to build a modern winery building, inspired by the architectural style of the Dominican Order.\n\nIn 1978, Cécile Chancel decided to build a garden in the style of a 17th-century kitchen garden. She had terraces dug on the hillside next to the vineyards, researched different garden styles, and, with the assistance of landscape gardener Tobie Loup de Vian, began building. The garden reached its present form by 1990. It was classified as a Remarkable Garden of France in 2005.\nDescription\nThe gardens are laid out on three terraces:\n\nThe upper terrace is a kitchen garden and flower garden, featuring lavender cut into spheres, squash, salad plants, fennel, and aromatic plants and herbs. Different varieties of tomatoes are grown on bamboo frames, and there are pyramids of ivy and hops (Humulus lupulus).\n\nThe middle terrace features flowers, particularly roses. The paths are bordered with Iris × germanica and with yew trees trimmed into cones.\n\nThe lower terrace features fruit trees, particularly old varieties of apples and pears. The garden also has a garden of herbs, a collection of asters, and boxwood hedges trimmed in ornamental forms.\n\nAn arbor or pergola covered with climbing roses and trumpet creeper (Campsis) climbs the hill and joins the three terraces.\n\nTables and seats are placed at scenic spots with views of the garden and the vineyards beyond. The best times to visit the garden are June and July for the flowers, or September for the change of colors of the vineyards and trees.",

        "evidence": "Research in social media analysis is recently seeing a surge in the number of research works applying representation learning models to solve high-level syntactico-semantic tasks such as sentiment analysis [1], semantic textual similarity computation [2], hashtag prediction [3] and so on. Though the performance of the representation learning models are better than the traditional models for all the tasks, little is known about the core properties of a tweet encoded within the representations. In a recent work, Hill et al. [4] perform a comparison of different sentence representation models by evaluating them for different high-level semantic tasks such as paraphrase identification, sentiment classification, question answering, document retrieval and so on. This type of coarse-grained analysis is opaque as it does not clearly reveal the kind of information encoded by the representations. Our work presented here constitutes the first step in opening the black-box of vector embeddings for social media posts, particularly tweets.\nEssentially we ask the following question: “What are the core properties encoded in the given tweet representation?”. We explicitly group the set of these properties into two categories: syntactic and social. Syntactic category includes properties such as tweet length, the order of words in it, the words themselves, slang words, hashtags and named entities in the tweet. On the other hand, social properties consist of `is reply', and `reply time'. We investigate the degree to which the tweet representations encode these properties. We assume that if we cannot train a classifier to predict a property based on its tweet representation, then this property is not encoded in this representation. For example, the model which preserves the tweet length should perform well in predicting the length given the representation generated from the model. Though these elementary property prediction tasks are not directly related to any downstream application, knowing that the model is good at modeling a particular property (e.g., the social properties) indicates that it could excel in correlated applications (e.g., user profiling task). In this work we perform an extensive evaluation of 9 unsupervised and 4 supervised tweet representation models, using 8 different properties. The most relevant work is that of Adi et al. [5], which investigates three sentence properties in comparing unsupervised sentence representation models such as average of words vectors and LSTM auto-encoders. We differ from their work in two ways: (1) While they focus on sentences, we focus on social media posts which opens up the challenge of considering multiple salient properties such as hashtags, named entities, conversations and so on. (2) While they work with only unsupervised representation-learning models, we investigate the traditional unsupervised methods (BOW, LDA), unsupervised representation learning methods (Siamese CBOW, Tweet2Vec), as well as supervised methods (CNN, BLSTM).\nOur main contributions are summarized below.\nThe paper is organized as follows. Sections 2 and 3 discuss the set of proposed elementary property prediction tasks and the models considered for this study respectively. Section 4 and 5 presents the experiment setup and result analysis respectively. We conclude the work with a brief summary in Section 5.\nIn this work we perform an extensive evaluation of 9 unsupervised and 4 supervised tweet representation models, using 8 different properties.",

The original feature dimensions are 2048 in both the cases. It is clear from the Figure FIGREF14 that most of the energy of the visual feature space resides in a low-dimensional subspace BIBREF14.

Figure FIGREF14 also shows the cumulative variance explained by Top 10, 20, 50 and 100 principal components respectively. It is clear that the visual features in the case of How2 dataset are much more dominated by the \"common\" dimensions, when compared to the Multi30k dataset.

First, we select different keywords to search twitter users of different categories. For example, to search self-claimed diagnosed PTSD sufferers, we select keywords related to PTSD for example, post trauma, post traumatic disorder, PTSD etc. We use a regular expression to search for statements where the user self-identifies as being diagnosed with PTSD. For example, Table TABREF27 shows a self-identified tweet posts. To search veterans, we mostly visit to different twitter accounts of veterans organizations such as \"MA Women Veterans @WomenVeterans\", \"Illinois Veterans @ILVetsAffairs\", \"Veterans Benefits @VAVetBenefits\" etc. We define an inclusion criteria as follows: one twitter user will be part of this study if he/she describes himself/herself as a veteran in the introduction and have at least 25 tweets in last week. After choosing the initial twitter users, we search for self-identified PTSD sufferers who claim to be diagnosed with PTSD in their twitter posts. We find 685 matching tweets which are manually reviewed to determine if they indicate a genuine statement of a diagnosis for PTSD. Next, we select the username that authored each of these tweets and retrieve last week's tweets via the Twitter API. We then filtered out users with less than 25 tweets and those whose tweets were not at least 75% in English (measured using an automated language ID system.) This filtering left us with 305 users as positive examples. We repeated this process for a group of randomly selected users. We randomly selected 3,000 twitter users who are veterans as per their introduction and have at least 25 tweets in last one week. After filtering (as above) in total 2,423 users remain, whose tweets are used as negative examples developing a 2,728 user's entire weeks' twitter posts where 305 users are self-claimed PTSD sufferers. We distributed Dryhootch chosen surveys among 1,200 users (305 users are self claimed PTSD sufferers and rest of them are randomly chosen from previous 2,423 users) and received 210 successful responses. Among these responses, 92 users were diagnosed as PTSD by any of the three surveys and rest of the 118 users are diagnosed with NO PTSD. Among the clinically diagnosed PTSD sufferers, 17 of them were not self-identified before. However, 7 of the self-identified PTSD sufferers are assessed with no PTSD by PTSD assessment tools. The response rates of PTSD and NO PTSD users are 27% and 12%. In summary, we have collected one week of tweets from 2,728 veterans where 305 users claimed to have diagnosed with PTSD. After distributing Dryhootch surveys, we have a dataset of 210 veteran twitter users among them 92 users are assessed with PTSD and 118 users are diagnosed with no PTSD using clinically validated surveys. The severity of the PTSD are estimated as Non-existent, light, moderate and high PTSD based on how many surveys support the existence of PTSD among the participants according to dryhootch manual BIBREF18, BIBREF19.\nThere are many clinically validated PTSD assessment tools that are being used both to detect the prevalence of PTSD and its intensity among sufferers. Among all of the tools, the most popular and well accepted one is Domain-Specific Risk-Taking (DOSPERT) Scale BIBREF15. This is a psychometric scale that assesses risk taking in five content domains: financial decisions (separately for investing versus gambling), health/safety, recreational, ethical, and social decisions. Respondents rate the likelihood that they would engage in domain-specific risky activities (Part I). An optional Part II assesses respondents' perceptions of the magnitude of the risks and expected benefits of the activities judged in Part I. There are more scales that are used in risky behavior analysis of individual's daily activities such as, The Berlin Social Support Scales (BSSS) BIBREF16 and Values In Action Scale (VIAS) BIBREF17. Dryhootch America BIBREF18, BIBREF19, a veteran peer support community organization, chooses 5, 6 and 5 questions respectively from the above mentioned survey systems to assess the PTSD among war veterans and consider rest of them as irrelevant to PTSD. The details of dryhootch chosen survey scale are stated in Table TABREF13. Table!TABREF14 shows a sample DOSPERT scale demographic chosen by dryhootch. The threshold (in Table TABREF13) is used to calculate the risky behavior limits. For example, if one individual's weekly DOSPERT score goes over 28, he is in critical situation in terms of risk taking symptoms of PTSD. Dryhootch defines the intensity of PTSD into four categories based on the weekly survey results of all three clinical survey tools (DOSPERT, BSSS and VIAS )\nWe distributed Dryhootch chosen surveys among 1,200 users (305 users are self claimed PTSD sufferers and rest of them are randomly chosen from previous 2,423 users) and received 210 successful responses. \nDryhootch defines the intensity of PTSD into four categories based on the weekly survey results of all three clinical survey tools (DOSPERT, BSSS and VIAS )",

        "question": "Where does the name Gibraltar come from?",
        "evidence": "Gibraltar (/dʒɪˈbrɔːltər/ jih-BRAWL-tər, Spanish: [xiβɾalˈtaɾ]) is a British Overseas Territory and city located at the southern tip of the Iberian Peninsula. It has an area of 6.7 km2 (2.6 sq mi) and is bordered to the north by Spain. The landscape is dominated by the Rock of Gibraltar, at the foot of which is a densely populated town area, home to over 32,000 people, primarily Gibraltarians.\n\nIn 1704, Anglo-Dutch forces captured Gibraltar from Spain during the War of the Spanish Succession. The territory was ceded to Great Britain in perpetuity under the Treaty of Utrecht in 1713. It became an important base for the Royal Navy, particularly during the Napoleonic Wars and World War II, as it controlled the narrow entrance and exit to the Mediterranean Sea, the Strait of Gibraltar, which is only 14.3 km (8.9 mi) wide. This choke point remains strategically important, with half the world's seaborne trade passing through it. Gibraltar's economy is based largely on tourism, online gambling, financial services, and bunkering.\n\nThe sovereignty of Gibraltar is a point of contention in Anglo-Spanish relations, as Spain asserts a claim to the territory. Gibraltarians overwhelmingly rejected proposals for Spanish sovereignty in a 1967 referendum, and for shared sovereignty in a 2002 referendum. Nevertheless, Gibraltar maintains close economic and cultural links with Spain, with many Gibraltarians speaking Spanish as well as a local dialect known as Llanito.\n\nSince Brexit, Gibraltar is not a member of the European Union but negotiations are underway to have it participate in the Schengen Agreement to facilitate border movements between Gibraltar and Spain. As of March 2023, talks seem deadlocked.\n\nName\nThe name is derived from Arabic: جبل طارق, romanized: Jabal Ṭāriq, lit. 'Mount of Tariq' (named after the 8th-century Moorish military leader Tariq ibn Ziyad).",

        "evidence": "Jiang Zemin (17 August 1926 – 30 November 2022) was a Chinese politician who served as general secretary of the Chinese Communist Party (CCP) from 1989 to 2002, as chairman of the Central Military Commission from 1989 to 2004, and as president of China from 1993 to 2003. Jiang was paramount leader of China from 1989 to 2002. He was the core leader of the third generation of Chinese leadership, one of four core leaders alongside Mao Zedong, Deng Xiaoping and Xi Jinping.\n\nBorn in Yangzhou, Jiangsu, Jiang joined the CCP while he was in college. After the establishment of the People's Republic of China in 1949, he received training at the Stalin Automobile Works in Moscow in the 1950s, later returning to Shanghai in 1962 to serve in various institutes, later being sent between 1970-1972 to Romania as part of an expert team to establish machinery manufacturing plants in the country. After 1979, he was appointed as the vice chair of two commissions by vice premier Gu Mu to oversee the newly-established special economic zones (SEZs). He became the vice minister of the newly-established Ministry of Electronics Industry and a member of the CCP Central Committee in 1982.\n\nJiang was appointed as the mayor of Shanghai in 1985, later being promoted to its Communist Party secretary, as well as a member of the CCP Politburo, in 1987. Jiang came to power unexpectedly as a compromise candidate following the 1989 Tiananmen Square protests and massacre, when he replaced Zhao Ziyang as CCP general secretary after Zhao was ousted for his support for the student movement. As the involvement of the \"Eight Elders\" in Chinese politics steadily declined, Jiang consolidated his hold on power to become the \"paramount leader\" in the country during the 1990s. Urged by Deng Xiaoping's southern tour in 1992, Jiang officially introduced the term \"socialist market economy\" in his speech during the 14th CCP National Congress held later that year, which accelerated \"opening up and reform\".\n\nUnder Jiang's leadership, China experienced substantial economic growth with the continuation of market reforms. The returning of Hong Kong from the United Kingdom in 1997 and of Macau from Portugal in 1999, and entry into the World Trade Organisation in 2001, were landmark moments of his era. China also witnessed improved relations with the outside world, while the Communist Party maintained its tight control over the state. Jiang faced criticism over human rights abuses, including the crackdown on the Falun Gong movement. His contributions to party doctrine, known as the \"Three Represents\", were written into the CCP constitution in 2002. Jiang gradually vacated his official leadership titles from 2002 to 2005, being succeeded in these roles by Hu Jintao, although he and his political faction continued to influence affairs until much later.

        "answer": "It is used for multi-task learning, in which a shared meta-network is used to learn the meta-knowledge of semantic composition among the different tasks.",
        "evidence": "Deep learning models have been widely used in many natural language processing (NLP) tasks. A major challenge is how to design and learn the semantic composition function while modeling a text sequence. The typical composition models involve sequential BIBREF0 , BIBREF1 , convolutional BIBREF2 , BIBREF3 , BIBREF4 and syntactic BIBREF5 , BIBREF6 , BIBREF7 compositional models.\nIn spite of their success, these models have two major limitations. First, they usually use a shared composition function for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Second, different composition functions are learned from scratch in different tasks. However, given a certain natural language, its composition functions should be the same (on meta-knowledge level at least), even if the tasks are different.\nTo address these problems, we need to design a dynamic composition function which can vary with different positions and contexts in a sequence, and share it across the different tasks. To share some meta-knowledge of composition function, we can adopt the multi-task learning BIBREF8 . However, the sharing scheme of most neural multi-task learning methods is feature-level sharing, where a subspace of the feature space is shared across all the tasks. Although these sharing schemes are successfully used in various NLP tasks BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , they are not suitable to share the composition function.\nIn this paper, inspired by recent work on dynamic parameter generation BIBREF15 , BIBREF16 , BIBREF17 , we propose a function-level sharing scheme for multi-task learning, in which a shared meta-network is used to learn the meta-knowledge of semantic composition among the different tasks. The task-specific semantic composition function is generated by the meta-network. Then the task-specific composition function is used to obtain the task-specific representation of a text sequence. The difference between two sharing schemes is shown in Figure 1 . Specifically, we use two LSTMs as meta and basic (task-specific) network respectively. The meta LSTM is shared for all the tasks. The parameters of the basic LSTM are generated based on the current context by the meta LSTM, therefore the composition function is not only task-specific but also position-specific. The whole network is differentiable with respect to the model parameters and can be trained end-to-end.\nWe demonstrate the effectiveness of our architectures on two kinds of NLP tasks: text classification and sequence tagging. Experimental results show that jointly learning of multiple related tasks can improve the performance of each task relative to learning them independently.\nOur contributions are of three-folds:\nIn this paper, inspired by recent work on dynamic parameter generation, we propose a function-level sharing scheme for multi-task learning, in which a shared meta-network is used to learn the meta-knowledge of semantic composition among the different tasks.",

        "question": "Is each utterance separated from overlapping voices and background noise?",
        "answer": "Yes, it is.",
        "evidence": "\nThe goal of meeting transcription is to have machines generate speaker-annotated transcripts of natural meetings based on their audio and optionally video recordings. Meeting transcription and analytics would be a key to enhancing productivity as well as improving accessibility in the workplace. It can also be used for conversation transcription in other domains such as healthcare BIBREF0. Research in this space was promoted in the 2000s by NIST Rich Transcription Evaluation series and public release of relevant corpora BIBREF1, BIBREF2, BIBREF3. While systems developed in the early days yielded high error rates, advances have been made in individual component technology fields, including conversational speech recognition BIBREF4, BIBREF5, far-field speech processing BIBREF6, BIBREF7, BIBREF8, and speaker identification and diarization BIBREF9, BIBREF10, BIBREF11. When cameras are used in addition to microphones to capture the meeting conversations, speaker identification quality could be further improved thanks to the computer vision technology. These trends motivated us to build an end-to-end audio-visual meeting transcription system to identify and address unsolved challenges. This report describes our learning, with focuses on overall architecture design, overlapped speech recognition, and audio-visual speaker diarization.\nWhen designing meeting transcription systems, different constraints must be taken into account depending on targeted scenarios. In some cases, microphone arrays are used as an input device. If the names of expected meeting attendees are known beforehand, the transcription system should be able to provide each utterance with the true identity (e.g., “Alice” or “Bob”) instead of a randomly generated label like “Speaker1”. It is often required to show the transcription in near real time, which makes the task more challenging.\nThis work assumes the following scenario. We consider a scheduled meeting setting, where an organizer arranges a meeting in advance and sends invitations to attendees. The transcription system has access to the invitees' names. However, actual attendees may not completely match those invited to the meeting. The users are supposed to enroll themselves in the system beforehand so that their utterances in the meeting can be associated with their names. The meeting is recorded with an audio-visual device equipped with a seven-element circular microphone array and a fisheye camera. Transcriptions must be shown with a latency of up to a few seconds.\nThis paper investigates three key challenges.\n\nSpeech overlaps: Recognizing overlapped speech has been one of the main challenges in meeting transcription with limited tangible progress. Numerous multi-channel speech separation methods were proposed based on independent component analysis or spatial clustering BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. However, there was little successful effort to apply these methods to natural meetings. Neural network-based single-channel separation methods using techniques like permutation invariant training (PIT) BIBREF18 or deep clustering (DC) BIBREF19 are known to be vulnerable to various types of acoustic distortion, including reverberation and background noise BIBREF20. In addition, these methods were tested almost exclusively on small-scale segmented synthetic data and have not been applied to continuous conversational speech audio. Although the recently held CHiME-5 challenge helped the community make a step forward to a realistic setting, it still allowed the use of ground-truth speaker segments BIBREF21, BIBREF22.\nWe address this long-standing problem with a continuous speech separation (CSS) approach, which we proposed in our latest conference papers BIBREF23, BIBREF24. It is based on an observation that the maximum number of simultaneously active speakers is usually limited even in a large meeting. According to BIBREF25, two or fewer speakers are active for more than 98% of the meeting time. Thus, given continuous multi-channel audio observation, we generate a fixed number, say $N$, of time-synchronous signals. Each utterance is separated from overlapping voices and background noise. Then, the separated utterance is spawned from one of the $N$ output channels. For periods where the number of active speakers is fewer than $N$, the extra channels generate zeros. We show how continuous speech separation can fit in with an overall meeting transcription architecture to generate speaker-annotated transcripts.\nNote that our speech separation system does not make use of a camera signal. While much progress has been made in audio-visual speech separation, the challenge of dealing with all kinds of image variations remains unsolved BIBREF26, BIBREF27, BIBREF28.\n\nExtensible framework: It is desirable that a single transcription system be able to support various application settings for both maintenance and scalability purposes. While this report focuses on the audio-visual setting, our broader work covers an audio-only setting as well as the scenario where no prior knowledge of meeting attendees is available. A modular and versatile architecture is desired to encompass these different settings.\nTo this end, we propose a framework called SRD, which stands for “separate, recognize, and diarize”, where CSS, speech recognition, and speaker diarization takes place in tandem. Performing CSS at the beginning allows the other modules to operate on overlap-free signals. Diarization is carried out after speech recognition because its implementation can vary significantly depending on the application settings. By choosing an appropriate diarization module for each setting, multiple use cases can be supported without changing the rest of the system. This architecture also allows transcriptions to be displayed in real time without speaker information. Speaker identities for each utterance may be shown after a couple of seconds.\n\nAudio-visual speaker diarization: Speaker diarization, a process of segmenting input audio and assigning speaker labels to the individual segments, can benefit from a camera signal. The phenomenal improvements that have been made to face detection and identification algorithms by convolutional neural networks (CNNs) BIBREF29, BIBREF30, BIBREF31 make the camera signal very appealing for speaker diarization. While much prior work assumes the batch processing scenario where the entire meeting recording can be processed multiple times, several studies deal with online processing BIBREF32, BIBREF33, BIBREF34, BIBREF35. However, no previous studies comprehensively address the challenges that one might encounter in real meetings. BIBREF32, BIBREF33 do not cope with speech overlaps. While the methods proposed in BIBREF34, BIBREF35 address the overlap issue, they rely solely on spatial cues and thus are not applicable when multiple speakers sit side by side.\nOur diarization method handles overlapping utterances as well as co-located speakers by utilizing the time-frequency (TF) masks generated by CSS in speaker identification and sound source localization (SSL). In addition, several enhancements are made to face identification to improve robustness to image variations caused by face occlusions, extreme head pose, lighting conditions, and so on.\nThe transcription system has access to the invitees' names. However, actual attendees may not completely match those invited to the meeting.",

        "evidence": "The main focus of this paper is to apply domain adaptation for SQA. In this approach, we have two SQA models (QANets), one trained from target domain data (ASR hypotheses) and another trained from source domain data (reference transcriptions). Because the two domains share common information, some layers in these two models can be tied in order to model the shared features. Hence, we can choose whether each layer in the QA model should be shared. Tying the weights between the source layer and the target layer in order to learn a symmetric mapping is to project both source and target domain data to a shared common space. Different combinations will be investigated in our experiments.\nMore specifically, we incorporate a domain discriminator into the SQA model shown in Figure FIGREF2 , which can enforce the embedding encoder to project the sentences from both source and target domains into a shared common space and consequentially to be ASR-error robust. Although the embedding encoder for both domains may implicitly learn some common latent representations, adversarial learning can provide a more direct training signal for aligning the output distribution of the embedding encoder from both domains. The embedding encoder takes in a sequence of word vectors and generates a sequence of hidden vectors with the same length. We use INLINEFORM0 and INLINEFORM1 ( INLINEFORM2 and INLINEFORM3 ) to represent the hidden vector sequence given the question INLINEFORM4 and the document INLINEFORM5 in the target (source) domain respectively.\nThe domain discriminator INLINEFORM0 focuses on identifying the domain of the vector sequence is from given INLINEFORM1 or INLINEFORM2 , where the objective is to minimize INLINEFORM3 . DISPLAYFORM0 \nGiven a training example from the target domain ( INLINEFORM0 ), INLINEFORM1 learns to assign a lower score to INLINEFORM2 and INLINEFORM3 in that example, that is, to minimize INLINEFORM4 and INLINEFORM5 . On the other hand, given a training example from the source domain ( INLINEFORM6 ), INLINEFORM7 learns to assign a larger value to INLINEFORM8 and INLINEFORM9 .\nFurthermore, we update the parameters of the embedding encoders to maximize the domain classification loss INLINEFORM0 , which works adversarially towards the domain discriminator. We thus expect the model to learn features and structures that can generalize across domains when the outputs of INLINEFORM1 are indistinguishable from the outputs of INLINEFORM2 . The loss function for embedding encoder, INLINEFORM3 , is formulated as DISPLAYFORM0 \nwhere INLINEFORM0 is a hyperparameter. The two embedding encoders in the QA model are learned to maximize INLINEFORM1 while minimizing the loss for QA, INLINEFORM2 . Because the parameters of other layers in QA model are independent to the loss of the domain discriminator, the loss function of other layers, INLINEFORM3 , is equivalent to INLINEFORM4 , that is, INLINEFORM5 .\nAlthough the discriminator is applied to the output of embedding encoder in Figure FIGREF2 , it can be also applied to other layers. Considering that almost all QA model contains such embedding encoders, the proposed approach is expected to generalize to other QA models in addition to QANet.\nMore specifically, we incorporate a domain discriminator into the SQA model shown in Figure 2, which can enforce the embedding encoder to project the sentences from both source and target domains into a shared common space and consequentially to be ASR-error robust.",

        "evidence": "Neural language models BIBREF0 , BIBREF1 , BIBREF2 have become an essential component in several areas of natural language processing (NLP), such as machine translation, speech recognition and image captioning. They have also become a common benchmarking application in machine learning research on recurrent neural networks (RNN), because producing an accurate probabilistic model of human language is a very challenging task which requires all levels of linguistic analysis, from pragmatics to phonology, to be taken into account.\nA typical language model is trained on text in a single language, and if one needs to model multiple languages the standard solution is to train a separate model for each language. This presupposes large quantities of monolingual data in each of the languages that needs to be covered and each model with its parameters is completely independent of any of the other models.\nWe propose instead to use a single model with real-valued vectors to indicate the language used, and to train this model with a large number of languages. We thus get a language model whose predictive distribution INLINEFORM0 is a continuous function of the language vector INLINEFORM1 , a property that is trivially extended to other neural NLP models. In this paper, we explore the “language space” containing these vectors, and in particular explore what happens when we move beyond the points representing the languages of the training corpus.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models. The second motivation is data sparseness, an issue that heavily influences the reliability of data-driven models. Resources are scarce for most languages in the world (and also for most domains in otherwise well-supported languages), which makes it hard to train reasonable parameters. By combining data from many languages, we hope to mitigate this issue.\nIn contrast to related work, we focus on massively multilingual data sets to cover for the first time a substantial amount of the linguistic diversity in the world in a project related to data-driven language modeling. We do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data. The only supervision that is giving during training is a language identifier as a one-hot encoding. From that and the actual training examples, the system learns dense vector representations for each language included in our data set along with the character-level RNN parameters of the language model itself.\nA typical language model is trained on text in a single language, and if one needs to model multiple languages the standard solution is to train a separate model for each language.",

It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide.\n\nChess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. White moves first, followed by Black. Checkmating the opponent's king involves putting the king under immediate attack (in \"check\") whereby there is no way for it to escape. There are also several ways a game can end in a draw.\n\nOrganized chess arose in the 19th century. Chess competition today is governed internationally by FIDE (the International Chess Federation). The first universally recognized World Chess Champion, Wilhelm Steinitz, claimed his title in 1886; Magnus Carlsen is the current World Champion. A huge body of chess theory has developed since the game's inception. Aspects of art are found in chess composition, and chess in its turn influenced Western culture and art, and has connections with other fields such as mathematics, computer science, and psychology.\n\nOne of the goals of early computer scientists was to create a chess-playing machine. In 1997, Deep Blue became the first computer to beat the reigning World Champion in a match when it defeated Garry Kasparov. Today's chess engines are significantly stronger than the best human players and have deeply influenced the development of chess theory.",

        "evidence": "Question generation (QG) is the task of generating a question from a reference sentence and a specified answer within the sentence. A major challenge in QG is to identify answer-relevant context words to finish the declarative-to-interrogative sentence transformation. Existing sequence-to-sequence neural models achieve this goal by proximity-based answer position encoding under the intuition that neighboring words of answers are of high possibility to be answer-relevant. However, such intuition may not apply to all cases especially for sentences with complex answer-relevant relations. Consequently, the performance of these models drops sharply when the relative distance between the answer fragment and other non-stop sentence words that also appear in the ground truth question increases. To address this issue, we propose a method to jointly model the unstructured sentence and the structured answer-relevant relation (extracted from the sentence in advance) for question generation. Specifically, the structured answer-relevant relation acts as the to the point context and it thus naturally helps keep the generated question to the point, while the unstructured sentence provides the full information. Extensive experiments show that to the point context helps our question generation model achieve significant improvements on several automatic evaluation metrics. Furthermore, our model is capable of generating diverse questions for a sentence which conveys multiple relations of its answer fragment.\nExisting sequence-to-sequence neural models achieve this goal by proximity-based answer position encoding under the intuition that neighboring words of answers are of high possibility to be answer-relevant.",

        "answer": "First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression. Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment.",
        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nBD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression (Jones et al., 2010). Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment (Coryell et al., 1998; Tohen et al., 2003; Goldberg and Harrow, 2004).",

It is the second longest-lived radioisotope of iodine, after iodine-129.\nIts half-life is 59.49 days and it decays by electron capture to an excited state of tellurium-125. This state is not the metastable 125mTe, but rather a lower energy state that decays immediately by gamma decay with a maximum energy of 35 keV. Some of the excess energy of the excited 125Te may be internally converted ejected electrons (also at 35 keV), or to x-rays (from electron bremsstrahlung), and also a total of 21 Auger electrons, which are produced at the low energies of 50 to 500 electron volts. Eventually, stable ground state 125Te is produced as the final decay product.\nIn medical applications, the internal conversion and Auger electrons cause little damage outside the cell which contains the isotope atom. The X-rays and gamma rays are of low enough energy to deliver a higher radiation dose selectively to nearby tissues, in \"permanent\" brachytherapy where the isotope capsules are left in place (125I competes with palladium-103 in such uses)\nBecause of its relatively long half-life and emission of low-energy photons which can be detected by gamma-counter crystal detectors, 125I is a preferred isotope for tagging antibodies in radioimmunoassay and other gamma-counting procedures involving proteins outside the body. The same properties of the isotope make it useful for brachytherapy, and for certain nuclear medicine scanning procedures, in which it is attached to proteins (albumin or fibrinogen), and where a half-life longer than that provided by 123I is required for diagnostic or lab tests lasting several days.\nIodine-125 can be used in scanning/imaging the thyroid, but iodine-123 is preferred for this purpose, due to better radiation penetration and shorter half-life (13 hours). 125I is useful for glomerular filtration rate (GFR) testing in the diagnosis or monitoring of patients with kidney disease. Iodine-125 is used therapeutically in brachytherapy treatments of tumors. For radiotherapy ablation of tissues that absorb iodine (such as the thyroid), or that absorb an iodine-containing radiopharmaceutical, the beta-emitter iodine-131 is the preferred isotope.",

        "evidence": "We posses a wealth of prior knowledge about many natural language processing tasks. For example, in text categorization, we know that words such as NBA, player, and basketball are strong indicators of the sports category BIBREF0 , and words like terrible, boring, and messing indicate a negative polarity while words like perfect, exciting, and moving suggest a positive polarity in sentiment classification.\nA key problem arisen here, is how to leverage such knowledge to guide the learning process, an interesting problem for both NLP and machine learning communities. Previous studies addressing the problem fall into several lines. First, to leverage prior knowledge to label data BIBREF1 , BIBREF2 . Second, to encode prior knowledge with a prior on parameters, which can be commonly seen in many Bayesian approaches BIBREF3 , BIBREF4 . Third, to formalise prior knowledge with additional variables and dependencies BIBREF5 . Last, to use prior knowledge to control the distributions over latent output variables BIBREF6 , BIBREF7 , BIBREF8 , which makes the output variables easily interpretable.\nHowever, a crucial problem, which has rarely been addressed, is the bias in the prior knowledge that we supply to the learning model. Would the model be robust or sensitive to the prior knowledge? Or, which kind of knowledge is appropriate for the task? Let's see an example: we may be a baseball fan but unfamiliar with hockey so that we can provide a few number of feature words of baseball, but much less of hockey for a baseball-hockey classification task. Such prior knowledge may mislead the model with heavy bias to baseball. If the model cannot handle this situation appropriately, the performance may be undesirable.\nIn this paper, we investigate into the problem in the framework of Generalized Expectation Criteria BIBREF7 . The study aims to reveal the factors of reducing the sensibility of the prior knowledge and therefore to make the model more robust and practical. To this end, we introduce auxiliary regularization terms in which our prior knowledge is formalized as distribution over output variables. Recall the example just mentioned, though we do not have enough knowledge to provide features for class hockey, it is easy for us to provide some neutral words, namely words that are not strong indicators of any class, like player here. As one of the factors revealed in this paper, supplying neutral feature words can boost the performance remarkably, making the model more robust.\nMore attractively, we do not need manual annotation to label these neutral feature words in our proposed approach.\nMore specifically, we explore three regularization terms to address the problem: (1) a regularization term associated with neutral features; (2) the maximum entropy of class distribution regularization term; and (3) the KL divergence between reference and predicted class distribution. For the first manner, we simply use the most common features as neutral features and assume the neutral features are distributed uniformly over class labels. For the second and third one, we assume we have some knowledge about the class distribution which will be detailed soon later.\nTo summarize, the main contributions of this work are as follows:\nThe rest of the paper is structured as follows: In Section 2, we briefly describe the generalized expectation criteria and present the proposed regularization terms. In Section 3, we conduct extensive experiments to justify the proposed methods. We survey related work in Section 4, and summarize our work in Section 5.\nIn this paper, we investigate into the problem in the framework of Generalized Expectation Criteria.

        "evidence": "The Indus Valley Civilisation (IVC), also known as the Indus Civilisation was a Bronze Age civilisation in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE, and in its mature form 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread. Its sites spanned an area from much of Pakistan, to northeast Afghanistan, and northwestern India. The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan.\n\nThe term Harappan is sometimes applied to the Indus civilisation after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab province of British India and is now Punjab, Pakistan. The discovery of Harappa and soon afterwards Mohenjo-daro was the culmination of work that had begun after the founding of the Archaeological Survey of India in the British Raj in 1861. There were earlier and later cultures called Early Harappan and Late Harappan in the same area. The early Harappan cultures were populated from Neolithic cultures, the earliest and best-known of which is Mehrgarh, in Balochistan, Pakistan. Harappan civilisation is sometimes called Mature Harappan to distinguish it from the earlier cultures.\n\nThe cities of the ancient Indus were noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, clusters of large non-residential buildings, and techniques of handicraft and metallurgy. Mohenjo-daro and Harappa very likely grew to contain between 30,000 and 60,000 individuals, and the civilisation may have contained between one and five million individuals during its florescence. A gradual drying of the region during the 3rd millennium BCE may have been the initial stimulus for its urbanisation. Eventually it also reduced the water supply enough to cause the civilisation's demise and to disperse its population to the east.\n\nAlthough over a thousand Mature Harappan sites have been reported and nearly a hundred excavated, there are five major urban centres: Mohenjo-daro in the lower Indus Valley (declared a UNESCO World Heritage Site in 1980 as \"Archaeological Ruins at Moenjodaro\"), Harappa in the western Punjab region, Ganeriwala in the Cholistan Desert, Dholavira in western Gujarat (declared a UNESCO World Heritage Site in 2021 as \"Dholavira: A Harappan City\"), and Rakhigarhi in Haryana.

Wraparound was initially developed in the 1980s as a means for maintaining youth with the most serious emotional and behavioral problems in their home and community. During the wraparound process, a team of individuals who are relevant to the well-being of the child or youth (e.g., family members, other natural supports, service providers, and agency representatives) collaboratively develop an individualized plan of care, implement this plan, and evaluate success over time. The wraparound plan typically includes formal services and interventions, together with community services and interpersonal support and assistance provided by friends, kin, and other people drawn from the family's social networks. The team convenes frequently to measure the plan's components against relevant indicators of success. Plan components and strategies are revised when outcomes are not being achieved.\n\nThe process of engaging the family, convening the team, developing the plan, implementing the plan, and transitioning the youth out of formal wraparound is typically facilitated by a trained care manager or “wraparound facilitator,” sometimes with the assistance of a family support worker. The wraparound process, and the plan itself, is designed to be culturally competent, strengths based, and organized around family members’ own perceptions of needs, goals, and likelihood of success of specific strategies.",

Some of these works utilize private user data, while some, like ours, use publicly available data. An example of a work that uses private data is Balduzzi et al. BIBREF8 . They use data from the Friend Finder system (which includes some private data) provided by various social networks to link users across services. Though one can achieve a relatively high level of success by using private data to link user accounts, we are interested in using only publicly available data for this task. In fact, as mentioned earlier, we do not even consider publicly available information that could explicitly identify a user, such as names, birthdays and locations.\nSeveral methods have been proposed for matching user profiles using public data BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 . These works differ from ours in two main aspects. First, in some of these works, the ground truth data is collected by assuming that all profiles that have the same screen name are from the same users BIBREF15 , BIBREF16 . This is not a valid assumption. In fact, it has been suggested that close to $20\\%$ of accounts with the same screen name in Twitter and Facebook are not matching BIBREF17 . Second, almost all of these works use features extracted from the user profiles BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 . Our work, on the other hand, is blind to the profile information and only utilizes users' activity patterns (linguistic and temporal) to match their accounts across different social networks. Using profile information to match accounts is contrary to the best practices of stylometry since it assumes and relies on the honesty, consistency and willingness of the users to explicitly share identifiable information about themselves (such as location).\nOur work, on the other hand, is blind to the profile information and only utilizes users’ activity patterns (linguistic and temporal) to match their accounts across different social networks.",

        "question": "How many RTE challenges have been created altogether?",
        "answer": "Seven.",
        "evidence": "The Recognizing Textual Entailment (RTE) challenges first appeared in 2004 as a means to test textual entailment, i.e. relations between a premise text and a hypothesis text ( \"Recognizing Textual Entailment\" ):\nAn entailment example from RTE1.\nBudapest again became the focus of national political drama in the late 1980s, when Hungary led the reform movement in eastern Europe that broke the communist monopoly on political power and ushered in the possibility of multiparty politics.\nIn the late 1980s Budapest became the center of the reform movement.\nEntailment [RTE702]\nIn contrast to the FraCaS test suite, the RTE challenges use naturally occurring data as premises. The hypothesis text is then constructed based on this premise text. There is either a binary or a tripartite classification of entailment — depending on the version of RTE. The first two RTE challenges follow the former scheme and make a binary classification of entailment (entailed or not entailed). Tripartite classification (entailment, negation of the hypothesis entailment or no entailment) is added in the later datasets, retaining two way classification versions as well. Seven RTE challenges have been created altogether.\nThe main advantages of the RTE challenges is their use of examples from natural text and the inclusion of cases that require presupposed information, mostly world knowledge. Indeed, the very definition of inference assumed in a number of the examples is problematic. As BIBREF1 have pointed out, RTE platforms suffer from cases of inference that should not be categorized as such. For these cases, a vast amount of world knowledge needs to be taken into consideration (that most importantly not every linguistic agent has). In this paper, and having the RTE as our starting point challenges, we claim that RTE is insufficiently precise to perform logical reasoning or precise reasoning tasks and we take up the task of validating our working hypothesis and proposing a method for doing proper collection of precise entailment pairs in the style of RTE. Of course, the creators of RTE had in mind a more loose definition of inference where both a precise and an imprecise definition of entailment would be at play. BIBREF2 mention that “our applied notion of textual entailment is also related, of course, to classical semantic entailment in the linguistics literature... a common definition of entailment specifies that a text t entails another text h (hypothesis, in our terminology) if h is true in every circumstance (possible world) in which t is true.\" This is close to what we want to capture in this paper. But, at the same time, BIBREF2 also mention that “however, our applied definition allows for cases in which the truth of the hypothesis is highly plausible, for most practical purposes, rather than certain\". It is these cases we want to make more precise, in the sense of making the supporting hidden inferences that are at play in many of the RTE examples explicit. In a way, what we are aiming at is a methodology of constructing entailment datasets in the style of RTE, that will involve a more precise definition of entailment and will further record any missing/hidden premises are used in justifying or not an entailment pattern.\nSeven RTE challenges have been created altogether.",

Flossing is important to remove build-up in between teeth in the areas a toothbrush cannot reach.

If plaque and calculus remain on teeth it can increase the risk of gum disease and cavities.  Maintaining a healthy mouth is important for oral health as well as systemic health, e.g. Cardiovascular Health.    Dentists recommend to brush your teeth twice a day for 2 minutes each time and flossing at least once a day.  When brushing it is best to wait 30 minutes after drinking acidic beverages, such as coffee or citrus juice.

        "evidence": "James became an unrestricted free agent at 12:01 am EDT on July 1, 2010. During this time, he was contacted by several teams, including the Bulls, Los Angeles Clippers, Miami Heat, New York Knicks, New Jersey Nets, and Cavaliers. On July 8, he announced on a live ESPN special titled The Decision that he would sign with the Heat. The telecast was broadcast from the Boys & Girls Club of Greenwich, Connecticut and raised $2.5 million for the charity. An additional $3.5 million was raised from advertising revenue, which was donated to other charities. The day before the special, fellow free agents Chris Bosh and Dwyane Wade also announced that they would sign with Miami; reports later arose that back in 2006 the trio had discussed among themselves their upcoming 2010 free agencies. James decided to join with Bosh and Wade in part so that he could shoulder less of the offensive load; he thought that his improved teammates would give him a better chance of winning an NBA championship than had he stayed in Cleveland. Heat president Pat Riley played a major role in selling James on the idea of playing with Bosh and Wade. James would be relieved of the burden of scoring, and he thought he could be the first player since Oscar Robertson to average a triple-double in a season.\nUpon leaving the Cavaliers, James drew intense criticism from sports analysts, executives, fans, and current and former players. The Decision itself was also scrutinized and viewed as unnecessary. Many thought that the prolonged wait for James's choice was unprofessional as not even the teams courting him were aware of his decision until moments before the show. Upon learning that James would not be returning to Cleveland, Cavaliers owner Dan Gilbert published an open letter to fans in which he aggressively denounced James's actions. Some angry fans of the team recorded videos of themselves burning his jersey. Former NBA players, including Michael Jordan and Magic Johnson, were also critical of James, condemning him for joining with Bosh and Wade in Miami and not trying to win a championship as \"the man\". James drew further criticism in a September interview with CNN when he claimed that race might have been a factor in the fallout from The Decision. As a result of his actions during the 2010 free agency period, he quickly gained a reputation as one of America's most disliked athletes, which was a radical change from prior years. The phrase \"taking my talents to South Beach\" became a punch line for critics. In retrospect, James has expressed some regret over his handling of The Decision.",

        "question": "Extract all the authors named in this paragraph on the controversies about Nobel laureate selections",
        "evidence": "From 1901 to 1912, the committee, headed by the conservative Carl David af Wirsén, weighed the literary quality of a work against its contribution towards humanity's struggle 'toward the ideal'. Leo Tolstoy, Henrik Ibsen, Émile Zola, and Mark Twain were rejected in favour of authors little read today.\n\nThe first prize in 1901, awarded to the French poet Sully Prudhomme, was heavily criticised. Many believed that the acclaimed Russian author Tolstoy should have been awarded the first Nobel prize in literature.\n\nThe choice of philosopher Rudolf Eucken as Nobel laureate in 1908 is widely considered to be one of the worst mistakes in the history of the Nobel Prize in Literature. The main candidates for the prize that year were poet Algernon Swinburne and author Selma Lagerlöf, but the Academy were divided between the candidates and, as a compromise, Eucken, representative of the Academy's interpretation of Nobel's \"ideal direction\", was launched as an alternative candidate that could be agreed upon.\n\nThe choice of Swedish writer Selma Lagerlöf as Nobel laureate in 1909 (for the \"lofty idealism, vivid imagination and spiritual perception that characterizes her writings\") followed fierce debate because of her writing style and subject matter, which broke literary decorums of the time.\n\nDuring World War I and its immediate aftermath, the committee adopted a policy of neutrality, favouring writers from non-combatant countries. The pacifistic author Romain Rolland was awarded the prize for 1915. Other years during the war Scandinavian writers were favoured, or the award was postponed.\n\nIn 1931 the prize was awarded posthumously to the poet and former permanent secretary of the Swedish Academy Erik Axel Karlfeldt, who had died earlier that year. The prize was controversial not just because it was the first and only time the Nobel Prize in Literature was awarded posthumously, but because the Academy had previously awarded two other Swedish writers of the same literary era, Selma Lagerlöf in 1909 and Verner von Heidenstam in 1916. Internationally it was heavily criticised as few had heard of Karlfeldt.\n\nThe Nobel Prize awarded to Pearl Buck in 1938 is one of the most criticised in the history of the prize. The Academy awarded Buck \"for her rich and truly epic descriptions of peasant life in China and for her biographical masterpieces\", referring to acclaimed and popular books published only a few years earlier. But her later work is generally not considered to be of the literary standard of a Nobel laureate.\n\nJohn Steinbeck received the 1962 Nobel Prize in Literature. The selection was heavily criticised, and described as \"one of the Academy's biggest mistakes\" in one Swedish newspaper. The New York Times asked why the Nobel committee gave the award to an author whose \"limited talent is, in his best books, watered down by tenth-rate philosophising\", adding, \"we think it interesting that the laurel was not awarded to a writer ... whose significance, influence and sheer body of work had already made a more profound impression on the literature of our age\".\n\nIn 1964, Jean-Paul Sartre was awarded the Nobel Prize in Literature, but he wrote declining it, stating that \"It is not the same thing if I sign Jean-Paul Sartre or if I sign Jean-Paul Sartre, Nobel Prize laureate. A writer must refuse to allow himself to be transformed into an institution, even if it takes place in the most honorable form.\" Nevertheless he was awarded the prize.\n\nSoviet dissident writer Aleksandr Solzhenitsyn, the 1970 prize laureate, did not attend the Nobel Prize ceremony in Stockholm for fear that the USSR would prevent his return afterwards (his works there were circulated in samizdat—clandestine form). After the Swedish government refused to honour Solzhenitsyn with a public award ceremony and lecture at its Moscow embassy, Solzhenitsyn refused the award altogether, commenting that the conditions set by the Swedes (who preferred a private ceremony) were \"an insult to the Nobel Prize itself.\" Solzhenitsyn did not accept the award and prize money until 10 December 1974, after he was deported from the Soviet Union. Within the Swedish Academy, member Artur Lundkvist had argued that the Nobel Prize in Literature should not become a political prize and questioned the artistic value of Solzhenitsyn's work.\n\nIn 1974, Graham Greene, Vladimir Nabokov, and Saul Bellow were believed to be likely candidates for the prize but the Academy decided on a joint award for Swedish authors Eyvind Johnson and Harry Martinson, both members of the Swedish Academy at the time, and unknown outside their home country. Bellow received the Nobel Prize in Literature in 1976; neither Greene nor Nabokov was awarded it.",

He distinguished it on grounds of physiology, morphology and voice, separating it from Townsend's storm petrel (Hydrobates socorroensis) which breeds on the same islands in the summer whereas Hydrobates cheimomnestes breeds in the winter. The species name cheimomnestes means \"winter suitor\", in reference to the fact that this bird breeds in the winter. There is still disagreement among authorities as to whether it should be regarded as a separate species. It is recognised as such by Avibase, but not by the International Union for Conservation of Nature.

        "answer": "When a golfer is setting up to hit a golf short, there are several things they need to take into account. First, they need to understand what club to hit based on the distance to the green, the elevation, wind speed and possibly the contours of the green. For beginning golfers, focusing on the center of the green is probably easiest. More skilled golfers should target areas closer to the pin or that leave them an easier putt or chip. The second step is lining up the shot. It's usually best to approach from the behind the ball to make sure your legs and body are aligned to the target. The target (pin, tree, etc) should take into account a golfers natural tendency to either draw (right to left) or fade (left to right) the ball as well as the direction and strength of the wind. The golfers stance will also affect the trajectory of a ball. If the golfers feet are above the ball or the ball is on a downhill lie, the ball will tend to go to the right. If the golfers feet are below the ball or the ball is on an uphill lie, the ball  will tend to go to the left. For left handed golfers, simple reverse the descriptions.",

And when we look closely, this doesn't really take a lot of tasks usually.\nIf you notice, you will realize that one can get (or feel like) totally busy with any amount of tasks and when multi-tasking and juggling between different things, the effectiveness of the work depends on how one is able to complete individual pieces with their utmost focus. When one is focussed on their work, distractions are the one of hinderances that comes in the path of effectiveness of a task. Distractions could come in the form of phone calls, emails, requests over online chats, scheduled meetings, someone walking into the workspace for a talk, etc and majority of them result in adding up some kind of work to be performed.

        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nWe evaluate our models on two typical tasks: text classi- fication and text semantic matching.",

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nWe present 4 attack modes for BAE based on the R and I operations, where for each token t in S: • BAE-R: Replace token t (See Algorithm 1) • BAE-I: Insert a token to the left or right of t • BAE-R/I: Either replace token t or insert a token to the left or right of t • BAE-R+I: First replace token t, then insert a token to the left or right of t Generating adversarial examples through masked language models has also been recently explored by Li et al.

Toilets that work with a tank system tend to work like residential toilets, but use less water and have a foot pedal for flushing.

First, cassette toilets are essentially holding tanks for toilet waste that are then pulled out of the RV and manually emptied. The “cassette” portion of the toilet is often on wheels, and can be emptied at either a dump station or in a public toilet. Composting toilets are the final common toilet type found in RVs. Composting toilets are a “dry” toilet, where waste goes into a holding tank with a composting material and becomes compost.

The empirical success of word embeddings raises an interesting research question: Beyond words, can we learn fixed-length distributed representations for pieces of texts? The texts can be of variable-length, ranging from paragraphs to documents. Such document representations play a vital role in a large number of downstream NLP/IR/ML applications, such as text clustering, sentiment analysis, and document retrieval, which treat each piece of text as an instance. Learning a good representation that captures the semantics of each document is thus essential for the success of such applications.\nIn this paper, we introduce KeyVec, a neural network model that learns densely distributed representations for documents of variable-length. In order to capture semantics, the document representations are trained and optimized in a way to recover key information of the documents. In particular, given a document, the KeyVec model constructs a fixed-length vector to be able to predict both salient sentences and key words in the document. In this way, KeyVec conquers the problem of prior embedding models which treat every word and every sentence equally, failing to identify the key information that a document conveys. As a result, the vectorial representations generated by KeyVec can naturally capture the topics of the documents, and thus should yield good performance in downstream tasks.\nWe evaluate our KeyVec on two text understanding tasks: document retrieval and document clustering. As shown in the experimental section SECREF5 , KeyVec yields generic document representations that perform better than state-of-the-art embedding models.\nAs a result, the vectorial representations generated by KeyVec can naturally capture the topics of the documents, and thus should yield good performance in downstream tasks.",

We have selected 7,020 positive tweets and 7,020 negative tweets randomly to generate a balanced dataset.\nFor Turkish, as the first dataset, we utilised the movie reviews which are collected from a popular website[https://www.beyazperde.com]. The number of reviews in this movie corpus is 20,244 and the average number of words in reviews is 39. Each of these reviews has a star-rating score which is indicative of sentiment. These polarity scores are between the values 0.5 and 5, at intervals of 0.5. We consider a review to be negative it the score is equal to or lower than 2.5. On the other hand, if it is equal to or higher than 4, it is assumed to be positive. We have randomly selected 7,020 negative and 7,020 positive reviews and processed only them.",

        "answer": "Congratulations on your upcoming trip to the Amalfi Coast! It is one of the most beautiful coasts in the world. 5-day is a good length to visit the Amalfi Coast. To start, you can fly into Naples airport, and take a private transfer to Sorrento, Italy. You can also get to Sorrento by train or boat. Sorrento is a very convenient central point for your 5-day trip so you don't have to hotel hop. Spend the first day walk around Sorrento, and orient yourself on where the train station and the port is. Enjoy a delicious dinner on the hills. \n\nDay 2, visit Positano and Praiano. Both are beautiful little towns and can be visited and explored on foot. You can easily get to both places by water taxi. \n\nDay 3. Book a boat tour to visit the famous Capri and the Blue Grotto. You will be amazed by the beautiful color of the Blue Grotto. However if you are going in high season, expect a wait to enter the Blue Grotto. Capri island has a lot to be discovered, and don't miss the funicular!\n\nDay 4: Visit 2 of the most beautiful manors on the Amalfi Coast in Ravello: Villa Cimbrone and Villa Rufolo. Have a meal there to enjoy the surroundings and the views. Then walk around the town of Ravello.\n\nDay 5: Go back to Naples for a day to enjoy the pizza, and historical city. If you can make a stop at Pompeii, that'd be a wonderful visit as well.",

        "evidence": "Question answering (QA) has drawn a lot of attention in the past few years. QA tasks on images BIBREF0 have been widely studied, but most focused on understanding text documents BIBREF1 . A representative dataset in text QA is SQuAD BIBREF1 , in which several end-to-end neural models have accomplished promising performance BIBREF2 . Although there is a significant progress in machine comprehension (MC) on text documents, MC on spoken content is a much less investigated field. In spoken question answering (SQA), after transcribing spoken content into text by automatic speech recognition (ASR), typical approaches use information retrieval (IR) techniques BIBREF3 to find the proper answer from the ASR hypotheses. One attempt towards QA of spoken content is TOEFL listening comprehension by machine BIBREF4 . TOEFL is an English examination that tests the knowledge and skills of academic English for English learners whose native languages are not English. Another SQA corpus is Spoken-SQuAD BIBREF5 , which is automatically generated from SQuAD dataset through Google Text-to-Speech (TTS) system. Recently ODSQA, a SQA corpus recorded by real speakers, is released BIBREF6 .\nTo mitigate the impact of speech recognition errors, using sub-word units is a popular approach for speech-related downstream tasks. It has been applied to spoken document retrieval BIBREF7 and spoken term detection BIBREF8 The prior work showed that, using phonectic sub-word units brought improvements for both Spoken-SQuAD and ODSQA BIBREF5 .\nInstead of considering sub-word features, this paper proposes a novel approach to mitigate the impact of ASR errors. We consider reference transcriptions and ASR hypotheses as two domains, and adapt the source domain data (reference transcriptions) to the target domain data (ASR hypotheses) by projecting these two domains in the shared common space. Therefore, it can effectively benefit the SQA model by improving the robustness to ASR errors in the SQA model.\nDomain adaptation has been successfully applied on computer vision BIBREF9 and speech recognition BIBREF10 . It is also widely studied on NLP tasks such as sequence tagging and parsing BIBREF11 , BIBREF12 , BIBREF13 . Recently, adversarial domain adaptation has already been explored on spoken language understanding (SLU). Liu and Lane learned domain-general features to benefit from multiple dialogue datasets BIBREF14 ; Zhu et al. learned to transfer the model from the transcripts side to the ASR hypotheses side BIBREF15 ; Lan et al. constructed a shared space for slot tagging and language model BIBREF16 .

Each is a network of firms, owned and managed independently, which have entered into agreements with the other member firms in the network to share a common name, brand, intellectual property, and quality standards. Each network has established a global entity to co-ordinate the activities of the network.\n\nUntil 2020, KPMG was the only Big Four firm not registered as a UK private company, but rather the co-ordinating entity was a Swiss association (verein). However, KPMG International changed its legal structure from a verein to a co-operative under Swiss law in 2003, then to a UK limited company in 2020. For Deloitte, PricewaterhouseCoopers and Ernst & Young, the co-ordinating entity is a UK limited company. Those entities do not themselves perform external professional services, nor do they own or control the member firms. Nevertheless, these networks colloquially are referred to as \"firms\" for the sake of simplicity and to reduce confusion with lay-people. These accounting and professional services networks are similar in nature to how law firm networks in the legal profession work.\n\nIn many cases, each member firm practices in a single country, and is structured to comply with the regulatory environment in that country.\n\nErnst & Young also includes separate legal entities which manage three of its four geographic areas: the Americas, Asia-Pacific, and EMEIA (Europe, the Middle East, India and Africa) groups, the fourth area being Japan, which has no larger co-ordination branch. These entities coordinate services performed by local firms within their respective areas, but do not perform services or hold ownership in the local entities.

        "answer": "Conversational systems that are able to interact with one or more people or chatbots in a multi-party chat.",
        "evidence": "Back to 42 BC, the philosopher Cicero has raised the issue that although there were many Oratory classes, there were none for Conversational skills BIBREF0 . He highlighted how important they were not only for politics, but also for educational purpose. Among other conversational norms, he claimed that people should be able to know when to talk in a conversation, what to talk depending on the subject of the conversation, and that they should not talk about themselves.\nNorms such as these may become social conventions and are not learnt at home or at school. Social conventions are dynamic and may change according to context, culture and language. In online communication, new commonsense practices are evolved faster and accepted as a norm BIBREF1 , BIBREF2 . There is not a discipline for that on elementary or high schools and there are few linguistics researchers doing research on this field.\nOn the other hand, within the Artificial Intelligence area, some Conversational Systems have been created in the past decades since the test proposed by Alan Turing in 1950. The test consists of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from that of a human BIBREF3 . Turing proposed that a human evaluator would judge natural language conversations between a human and a machine that is designed to generate human-like responses. Since then, many systems have been created to pass the Turing's test. Some of them have won prizes, some not BIBREF4 . Although in this paper we do not focus on creating a solution that is able to build conversational systems that pass the Turing's test, we focus on NDS. From BIBREF5 , \"NDS are systems that try to improve usability and user satisfaction by imitating human behavior\". We refer to Conversational Systems as NDS, where the dialogues are expressed as natural language texts, either from artificial intelligent agents (a.k.a. bots) or from humans.\nThat said, the current popular name to systems that have the ability to make a conversation with humans using natural language is Chatbot. Chatbots are typically used in conversational systems for various practical purposes, including customer service or information acquisition. Chatbots are becoming more widely used by social media software vendors. For example, Facebook recently announced that it would make Facebook Messenger (its 900-million-user messaging app by 2016), into a full-fledged platform that allows businesses to communicate with users via chatbots. Google is also building a new mobile-messaging service that uses artificial intelligence know-how and chatbot technology. In addition, according to the Wall Street Journal, there are more than 2 billion users of mobile apps. Still, people can be reluctant to install apps. So it is believed that social messaging can be a platform and chatbots may provide a new conversational interface for interacting with online services, as chatbots are easier to build and deploy than apps BIBREF6 .\nChina seems to be the place where chatbots adoption and use is most advanced today. For example, China's popular WeChat messaging platform can take payments, scan QR codes, and integrate chatbot systems. WeChat integrates e-mail, chat, videocalls and sharing of large multimedia files. Users can book flights or hotels using a mixed, multimedia interaction with active bots. WeChat was first released in 2011 by Tecent, a Chinese online-gaming and social-media firm, and today more than 700 million people use it, being one of the most popular messaging apps in the world (The Economist 2016). WeChat has a mixture of real-live customer service agents and automated replies (Olson 2016).\nStill, current existing chatbot engines do not properly handle a group chat with many users and many chatbots. This makes the chatbots considerably less social, which is a problem since there is a strong demand of having social chatbots that are able to provide different kinds of services, from traveling packages to finance advisors. This happens because there is a lack of methods and tools to design and engineer the coordination and mediation among chatbots and humans, as we present in Sections 2 and 3. In this paper, we refer to conversational systems that are able to interact with one or more people or chatbots in a multi-party chat as MPCS. Altogether, this paper is not meant to advance the state of the art on the norms for MPCS. Instead, the main contributions of this paper are threefold:\nWe then present some discussion and future work in the last section.\nIn this paper, we refer to conversational systems that are able to interact with one or more people or chatbots in a multi-party chat as Multi-Party Conversational System ( MPCS).",

        "evidence": "",
        "answer": "Strokes gained is a method of measuring a golfer's performance that revolutionized how people think about golf strategy and how they compare the performance of golfers.  \n\nSimply put, strokes gained measures how many strokes a player gains on every shot they hit in a round of golf.  \n\nFor example, if a player stands on the tee of a par 4 that is 375 yards long, their expected score for the hole for their skill level would be 4.0 strokes.  Assume they hit a strong drive of 275 yards, and land in the fairway.  Now their expected score for the hole might be 3.8.  Since their expected score went from 4.0 to 3.8 as a result of the drive, they gained .2 strokes with the drive.\n\nIf you repeat this for every shot in a round of golf, you would gain a picture of strokes gained for the overall round.\n\nOne key to strokes gained is what an expected score is for each hole.  This was first calculated for tour pro players when shot by shot stats were available via the ShotLink system used in pro events.  With the advent of consumer-level shot tracking systems, it is now possible to generated expected scores for virtually all levels of golfers, and thus any golfer can track strokes gained for their round, as compared to any level of golfer.\n\nStrokes gained is typically further broken down into 4 categories : Off the tee, approach, around the green, and putting.\n\nThe insights available once strokes gained was available has allowed insights into what really allows golfer to separate themselves from their competition.  Most notably, strokes gained was able to show that skill in driving is much more of a separator than is putting skill.  This went against many decades of conventional wisdom.",

He is known for the allegorical novella Animal Farm (1945) and the dystopian novel Nineteen Eighty-Four (1949). His non-fiction works, including The Road to Wigan Pier (1937), documenting his experience of working-class life in the industrial north of England, and Homage to Catalonia (1938), an account of his experiences soldiering for the Republican faction of the Spanish Civil War (1936–1939), are as critically respected as his essays on politics, literature, language and culture.\n\nBlair was born in India, and raised and educated in England. After school he became an Imperial policeman in Burma, before returning to Suffolk, England, where he began his writing career as George Orwell—a name inspired by a favourite location, the River Orwell. He lived from occasional pieces of journalism, and also worked as a teacher or bookseller whilst living in London. From the late 1920s to the early 1930s, his success as a writer grew and his first books were published. He was wounded fighting in the Spanish Civil War, leading to his first period of ill health on return to England. During the Second World War he worked as a journalist and for the BBC. The publication of Animal Farm led to fame during his lifetime. During the final years of his life he worked on Nineteen Eighty-Four, and moved between Jura in Scotland and London. It was published in June 1949, less than a year before his death.\n\nOrwell's work remains influential in popular culture and in political culture, and the adjective \"Orwellian\"—describing totalitarian and authoritarian social practices—is part of the English language, like many of his neologisms, such as \"Big Brother\", \"Thought Police\", \"Room 101\", \"Newspeak\", \"memory hole\", \"doublethink\", and \"thoughtcrime\".

In part, this is because there is not one single definition of art! \n\nSome people consider art a creative process that gives only aesthetic pleasure, and does not serve any utilitarian purpose. However, even with this definition, there is not a clear dividing line between art and utilitarian creative processes. For example, some people consider the literary arts to comprise poetry, fiction, non-fiction, and drama. We can clearly understand that non-fiction has a utilitarian purpose to educate and communicate, and arguably the other literary arts do too. So that definition of art as serving no utilitarian purpose is not very black-and-white. \n\nIf we consider art to be any creative endeavor that provides aesthetic pleasure, and that it might also be utilitarian, then there are many forms of art. Below is a partial listing, together with some of the ways these are commonly grouped together. \n\n\nArt form | Can be classified as\nPoetry | Literary arts, fine arts\nFiction | Literary arts\nNon-fiction | Literary arts\nDrama / theater | Performing arts, literary arts\nSculpture | Visual arts, fine arts, plastic arts\nPainting | Visual arts, fine arts\nGlassblowing | Visual arts\nCeramics | Visual arts, plastic arts\nOrigami | Visual arts, plastic arts\nWoodworking | Sculpture, plastic arts\nMusic | Performing arts, fine arts\nDance | Performing arts, fine arts\nFilm-making / cinematography | Performing arts, visual arts, media arts\nPhotography | Visual arts, media arts\nOpera | Performing arts, visual arts\nFood preparation | Culinary arts\nFood styling | Visual arts, culinary arts\nArchitecture | Fine arts\n\nThere are also subcategories of many of these art forms, for example:\nSculpture using different materials can have its own subcategory. Some people consider glassblowing or wood carving to be subcategories of sculpture.\nWoodworking has sub-specialties including engraving, furniture-making, and carving.\n  \nThere is also disagreement about including utilitarian disciplines as a form of art. Architecture is a good example of this. It is highly regulated, requires engineering skill, and provides clear useful benefits, so it doesn’t meet the standard of “purely aesthetic”. Still, it is common to consider architecture an art form, and most people agree that architecture can provide aesthetic pleasure.\n\nAs you can see, there isn’t a single way to classify art forms, although there is consensus about some of the most common groupings.",

        "answer": "Space-based telescopes have the advantage of being above the blurring effects of the Earth's atmosphere. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth's atmosphere. Only the wavelengths of visible light, a portion of infrared, and part of the radio wavelengths reach Earth. To observe other parts of the spectrum - ultraviolet, x-rays, gamma rays or infrared, telescopes have to be outside of Earth's atmosphere. Studying gamma-rays for example, helps astronomers learn more about things like blazars, gamma-ray bursts, pulsars and solar flares than would be possible with just optical telescopes. Similarly, studying x-rays gives invaluable information about the very hot regions of the universe such as exploded stars, clusters of galaxies, and the matter around black holes.

Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nIn this work, we develop a technique to rapidly transfer an existing pretrained model from English to other languages.",

The movement of electric charges is an electric current and produces a magnetic field. In most applications, a force acts on a charge with a magnitude given by Coulomb's law. Electric potential is typically measured in volts.\nElectricity is at the heart of many modern technologies, being used for:\na.

However, using several approaches and datasets such as the one proposed here can bring about a more thorough examination of inappropriate biases in modern machine learning systems.\nWe found that more than 75% of the systems tend to mark sentences involving one gender/race with higher intensity scores than the sentences involving the other gender/race. We found such biases to be more widely prevalent for race than for gender. We also found that the bias can be different depending on the particular affect dimension involved.",

Is this a characterization of the datasets used?",
        "answer": "Yes! Our core focus is active learning as a means to resolve task ambiguity. Real world datasets exhibit a range of phenomena that make specifying the desired task challenging (e.g. spurious correlations, latent subgroups, etc). We conduct experiments on four diverse datasets where task ambiguity is salient to test whether active learning helps the model acquire the correct behavior.",
        "evidence": "Modern pretrained models can be adapted to new tasks with remarkably little data, enabling downstream applications for tasks with only tens or hundreds of examples. However, an important but neglected challenge that is especially salient in few-shot settings is task ambiguity, when the desired behavior is not uniquely specified by the provided examples. Task ambiguity can manifest in different ways: For example, the class-relevant features of an input (e.g., the shape of an object in Figure) may be spuriously correlated with other features predictive of the training labels (e.g., the color of the object), making the desired task unclear. In addition, task ambiguity may arise from an underdiverse training set, causing models to be unsure of the desired behavior for minority groups or during distribution shifts that occur at test-time.\nWe consider whether the task ambiguity problem can be addressed through active learning, where models select informative examples for users to label. In principle, active learning allows models themselves to assist in resolving task ambiguity by identifying examples whose labels would be informative; for example, in fig., asking for the label of the blue square helps determine that the desired task is to predict the object shape not the object color. Since it may be challenging in general for users to intuit possible sources of task ambiguity, much less how to address them with example selection, an automated active learning approach may be desirable.\nIn traditional settings with smaller, unpretrained models, several challenges often prevent active learning from seeing success in practice, including label noise, unlearnable examples, and a lack of generalizability across models and tasks. However, using pretrained models in few-shot or low-data settings has several key differences from traditional ML pipelines which may make them particularly well-suited for active learning. First, the effect of an individual data point (and the difference between an informative vs. an uninformative one) is magnified, compared to the thousands or millions of examples typically acquired through standard active learning pipelines. Second, pretrained models excel at learning high-level representations of inputs, which better surface relevant features and may encourage active learning to select examples that disambiguate between these high-level features (e.g. shape and color).\nWe consider the use of active learning on a range of spuriously correlated, imbalanced, or domain shifted datasets where task ambiguity is salient. We compare an active learning approach with a random-sampling baseline, and compare the difference in performance with and without the use of pretrained models. Our contributions are:\n1. Identifying and motivating task ambiguity as a unified concern across a range of real-world datasets, and an especially salient problem for low-data settings.\n2. Proposing active learning as a potential solution, along with a simple yet practical recipe that does not require adjustment for new datasets or tuning on validation data.\n3. Showing that active learning can enable large gains (up to 6× reduction in data points, +12% absolute gain for the same labeling budget) and presenting scaling trends demonstrating that this is an emergent property of pretraining.\nSpurious correlations arise when multiple features are predictive of the label in a training dataset, yet it is ambiguous which ones are causally linked to the task label. We consider two such datasets, and see whether active learning can choose the disambiguating examples where the spurious features are not copresent with the causal features:\nWaterbirds The Waterbirds dataset consists of photographs of landbirds or waterbirds digitally edited onto land or water backgrounds. The task is to classify whether the bird is a landbird or a waterbird. In the train set, 77% of the pictures feature landbirds and 23% waterbirds. 95% of both landbirds and waterbirds appear on land and water backgrounds, respectively. In the validation and test sets, this percentage is decreased to 50%, instead. Thus, the image background is a spurious feature the model may come to rely on when making the prediction.\nTreeperson As the Waterbirds dataset was synthetically generated, we also consider a dataset where we perform classification over real, unedited images with spuriously correlated objects. We use the object annotations in Visual Genome to create a new dataset of 8,638 images called Treeperson, for which the task is to predict whether a person is in a given image. While 50% of the images contain a person in this dataset, each image also contains either a tree or a building, and the presence of these objects is spuriously correlated with the presence of people. At train time, 90% of training images with people contain a building, while 90% of training images without people contain a tree. Thus, a model may be incentivized to form representations that classify according to the presence of trees and buildings, rather than the presence of the actual causal variable of interest (people). These values are changed to 50% at test time, removing this correlation to evaluate how well the model learned the actual feature of interest.

In this paper, we propose simple yet effective methods to improve word-by-word translation of cross-lingual embeddings, using only monolingual corpora but without any back-translation. We integrate a language model for context-aware search, and use a novel denoising autoencoder to handle reordering. Our system surpasses state-of-the-art unsupervised neural translation systems without costly iterative training. We also analyze the effect of vocabulary size and denoising type on the translation performance, which provides better understanding of learning the cross-lingual word embedding and its usage in translation.\nBuilding a machine translation (MT) system requires lots of bilingual data. Neural MT models BIBREF0 , which become the current standard, are even more difficult to train without huge bilingual supervision BIBREF1 . However, bilingual resources are still limited to some of the selected language pairs—mostly from or to English.\nA workaround for zero-resource language pairs is translating via an intermediate (pivot) language. To do so, we need to collect parallel data and train MT models for source-to-pivot and pivot-to-target individually; it takes a double effort and the decoding is twice as slow.\nUnsupervised learning is another alternative, where we can train an MT system with only monolingual corpora. Decipherment methods BIBREF2 , BIBREF3 are the first work in this direction, but they often suffer from a huge latent hypothesis space BIBREF4 .\nRecent work by unmt-artetxe and unmt-facebook train sequence-to-sequence MT models of both translation directions together in an unsupervised way. They do back-translation BIBREF5 back and forth for every iteration or batch, which needs an immensely long time and careful tuning of hyperparameters for massive monolingual data.\nHere we suggest rather simple methods to build an unsupervised MT system quickly, based on word translation using cross-lingual word embeddings. The contributions of this paper are:\nThe proposed models can be efficiently trained with off-the-shelf softwares with little or no changes in the implementation, using only monolingual data. The provided analyses help for better learning of cross-lingual word embeddings for translation purpose. Altogether, our unsupervised MT system outperforms the sequence-to-sequence neural models even without training signals from the opposite translation direction, i.e. via back-translation.\nIn this paper, we propose simple yet effective methods to improve word-by-word translation of crosslingual embeddings, using only monolingual corpora but without any back-translation.****Altogether, our unsupervised MT system outperforms the sequence-to-sequence neural models even without training signals from the opposite translation direction, i.e. via backtranslation.",

        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized.",

The oos-threshold method is a more general decision rule that can be applied to any model that produces a probability.

        "evidence": "Our datasets can be used for various hate speech tasks. In this paper, we focus on generative hate speech intervention.\nThe goal of this task is to generate a response to hate speech that can mitigate its use during a conversation. The objective can be formulated as the following equation:\nwhere $c$ is the conversation, $r$ is the corresponding intervention response, and $D$ is the dataset. This task is closely related to the response generation and dialog generation, though several differences exist including dialog length, language cadence, and word imbalances. As a baseline, we chose the most common methods of these two tasks, such as Seq2Seq and VAE, to determine the initial feasibility of automatically generate intervention responses. More recent Reinforcement Learning method for dialog generation BIBREF21 can also be applied to this task with slight modification. Future work will explore more complex, and unique models.\nSimilar to BIBREF21, a generative model is considered as an agent. However, different from dialog generation, generative intervention does not have multiple turns of utterance, so the action of the agent is to select a token in the response. The state of the agent is given by the input posts and the previously generated tokens. Another result due to this difference is that the rewards with regard to ease of answering or information flow do not apply to this case, but the reward for semantic coherence does. Therefore, the reward of the agent is:\nwhere $rw(c,r)$ is the reward with regard to the conversation $c$ and its reference response $r$ in the dataset. $p(r|c)$ denotes the probability of generating response $r$ given the conversation $c$, and $p_{back}(c|r)$ denotes the backward probability of generating the conversation based on the response, which is parameterized by another generation network. The reward is a weighted combination of these two parts, which are observed after the agent finishing generating the response. We refer the readers to BIBREF21 for details.\nOur datasets can be used for various hate speech tasks. In this paper, we focus on generative hate speech intervention.",

        "evidence": "",
        "answer": "Tides are very long waves moving across the ocean and are caused by the gravitational forces exerted on the earth by the moon. When the highest point in the long-period wave reaches a shoreline the area experiences high tide. When the lowest point of the wave, the trough, reaches shore the area experiences low tide. The earth is mostly water and the water \"points\" at the moon, the parts of the Earth experiencing high tide is the water drawing towards the moon. The \"pointing\" water that faces the moon is formed because the gravitational pull of the moon is strongest on whichever side of the Earth faces it. Gravity pulls the ocean towards the moon and high tide occurs.\n\nThe bulge on the far side of the Earth is caused by inertia. The water moving away from the moon resists the gravitational forces that attempt to pull it in the opposite direction. Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs. As the Earth spins, different areas of the planet face the moon, and this rotation causes the tides to cycle around the planet.",

        "evidence": "Writing errors can occur in many different forms – from relatively simple punctuation and determiner errors, to mistakes including word tense and form, incorrect collocations and erroneous idioms. Automatically identifying all of these errors is a challenging task, especially as the amount of available annotated data is very limited. Rei2016 showed that while some error detection algorithms perform better than others, it is additional training data that has the biggest impact on improving performance.\nBeing able to generate realistic artificial data would allow for any grammatically correct text to be transformed into annotated examples containing writing errors, producing large amounts of additional training examples. Supervised error generation systems would also provide an efficient method for anonymising the source corpus – error statistics from a private corpus can be aggregated and applied to a different target text, obscuring sensitive information in the original examination scripts. However, the task of creating incorrect data is somewhat more difficult than might initially appear – naive methods for error generation can create data that does not resemble natural errors, thereby making downstream systems learn misleading or uninformative patterns.\nPrevious work on artificial error generation (AEG) has focused on specific error types, such as prepositions and determiners BIBREF0 , BIBREF1 , or noun number errors BIBREF2 . Felice2014a investigated the use of linguistic information when generating artificial data for error correction, but also restricting the approach to only five error types. There has been very limited research on generating artificial data for all types, which is important for general-purpose error detection systems. For example, the error types investigated by Felice2014a cover only 35.74% of all errors present in the CoNLL 2014 training dataset, providing no additional information for the majority of errors.\nIn this paper, we investigate two supervised approaches for generating all types of artificial errors. We propose a framework for generating errors based on statistical machine translation (SMT), training a model to translate from correct into incorrect sentences. In addition, we describe a method for learning error patterns from an annotated corpus and transplanting them into error-free text. We evaluate the effect of introducing artificial data on two error detection benchmarks. Our results show that each method provides significant improvements over using only the available training set, and a combination of both gives an absolute improvement of 4.3% in INLINEFORM0 , without requiring any additional annotated data.\n \nWe propose a framework for generating errors based on statistical machine translation (SMT), training a model to translate from correct into incorrect sentences.",

The Jeep Wrangler platform first became available in 1987 and has become one of the most recognizable vehicles manufactured today.  The love Wrangler owners have for their vehicles stems from the utilitarian nature of the platform, the ability to remove the top and doors in warmer weather, the wide array of aftermarket modifications available, as well as its extensive off road capabilities directly off the showroom floor. Jeep enthusiasts, also known as “Jeepers,” often wave at each other when passing in opposite directions.  This tradition stemmed from the use of the Willy’s model in the US military where out of reverence and courtesy passing soldiers driving their Jeeps would wave or salute each other depending on rank.

Here are some steps to follow to help you swim in the ocean:\n\nChoose a Safe Location: Before entering the water, make sure you choose a safe location to swim. Look for a spot that's away from strong currents, riptides, and waves. Avoid swimming alone, and make sure there are other people around in case you need help.\n\nCheck the Conditions: Before entering the water, check the weather and ocean conditions. Avoid swimming if there are strong winds, high waves, or thunderstorms. If there are lifeguards on duty, ask them about the current conditions and any potential hazards.\n\nWear Proper Gear: Make sure you wear proper swimwear, such as a wetsuit or rash guard, to protect your skin from the sun and ocean elements. Consider wearing fins or a snorkel to help you swim more efficiently.\n\nPractice Good Swimming Technique: When swimming in the ocean, use good swimming technique to help conserve your energy. Avoid swimming against the current, and swim parallel to the shore if you need to move sideways. Use a slow, steady stroke to conserve energy.\n\nBe Aware of Marine Life: When swimming in the ocean, be aware of any marine life that may be in the water. Avoid swimming near schools of fish, and stay away from jellyfish and other potentially dangerous creatures. If you do encounter a shark or other predator, stay calm and swim away slowly.\n\nFollow Ocean Safety Rules: Finally, follow any ocean safety rules that are in place. For example, some beaches may have specific areas designated for swimming, while others may require you to wear a life jacket or avoid swimming during certain times of day.\n\nBy following these steps, you can enjoy a safe and enjoyable swimming experience in the ocean.

        "evidence": "",
        "answer": "Here is a proof by contradiction that the square root of 2 is irrational. First, recall that irrational numbers are numbers that cannot be written as p / q for integers p and q. Assume for contradiction that the square root of 2 is rational, which would mean that sqrt(2) = p / q for some integers p and q. Further assume without loss of generality that this fraction is in reduced form, meaning that p and q share no common factors. We can assume this because any integer fraction can be written in such a reduced form, so the existence of any rational representation for sqrt(2) would imply the existence of one in reduced form. Now we square both sides of the above equation, yielding\n\n2 = p^2 / q^2\n\nfor some integers p and q not sharing any common factors. Now multiply by q^2 to get\n\n2 * q^2 = p^2\n\nNote that the left hand side is even due to the factor of 2, so the right hand side p^2 is even as well. This means that p must be even as well, otherwise p^2 would not be even. So p can be written as 2 * x for some integer x. Substituting this into the above equation, we get\n\n2 * q^2 = (2 * x)^2 = 2^2 * x^2\n\nNote that both sides of the equation have a factor of 2 we can cancel. Doing this, we get\n\nq^2 = 2 * x^2\n\nBy an argument analogous to the one above, we can conclude that q is even. However this contradicts our assumption that p and q shared no common factors.

The most basic linguistic unit in Vietnamese is morpheme, similar with syllable or token in English and “hình vị” (phoneme) or “tiếng” (syllable) in Vietnamese. According to the structured rule of its, Vietnamese can have about 20,000 different syllables (tokens). However, there are about 8,000 syllables used the Vietnamese dictionaries. There are three methods to identify morphemes in Vietnamese text BIBREF10 .\nMorpheme is the smallest meaningful unit of Vietnamese.\nMorpheme is the basic unit of Vietnamese.\nMorpheme is the smallest meaningful unit and is not used independently in the syntax factor.\nIn computational linguistics, morpheme is the basic unit of languages as Leonard Bloomfield mentioned for English BIBREF11 . In our research for Vietnamese, we consider the morpheme as syllable, called “tiếng” in Vietnamese (as Nguyen’s definition BIBREF12 ).\nThe next concept in linguistics is word which has fully grammar and meaning function in sentences. For Vietnamese, word is a single morpheme or a group of morphemes, which are fixed and have full meaning BIBREF12 . According to Nguyen, Vietnamese words are able classified into two types, (1) 1- syllable words with fully meaning and (2) n-syllables words whereas these group of tokens are fixed. Vietnamese syllable is not fully meaningful. However, it is also explained in the meaning and structure characteristics. For example, the token “kỳ” in “quốc kỳ” whereas “quốc” means national, “kỳ” means flag. Therefore, “quốc kỳ” means national flag.\nConsider dictionary used for evaluating the corpus, extracting features for models, and evaluating the systems, there are many Vietnamese dictionaries, however we recommend the Vietnamese dictionary of Hoang Phe, so called Hoang Phe Dictionary.

        "evidence": "Change is a universal property of language. For example, English has changed so much that Renaissance-era texts like The Canterbury Tales must now be read in translation. Even contemporary American English continues to change and diversify at a rapid pace—to such an extent that some geographical dialect differences pose serious challenges for comprehensibility BIBREF0 . Understanding language change is therefore crucial to understanding language itself, and has implications for the design of more robust natural language processing systems BIBREF1 .\nLanguage change is a fundamentally social phenomenon BIBREF2 . For a new linguistic form to succeed, at least two things must happen: first, speakers (and writers) must come into contact with the new form; second, they must decide to use it. The first condition implies that language change is related to the structure of social networks. If a significant number of speakers are isolated from a potential change, then they are unlikely to adopt it BIBREF3 . But mere exposure is not sufficient—we are all exposed to language varieties that are different from our own, yet we nonetheless do not adopt them in our own speech and writing. For example, in the United States, many African American speakers maintain a distinct dialect, despite being immersed in a linguistic environment that differs in many important respects BIBREF4 , BIBREF5 . Researchers have made a similar argument for socioeconomic language differences in Britain BIBREF6 . In at least some cases, these differences reflect questions of identity: because language is a key constituent in the social construction of group identity, individuals must make strategic choices when deciding whether to adopt new linguistic forms BIBREF7 , BIBREF8 , BIBREF9 . By analyzing patterns of language change, we can learn more about the latent structure of social organization: to whom people talk, and how they see themselves.\nBut, while the basic outline of the interaction between language change and social structure is understood, the fine details are still missing: What types of social network connections are most important for language change? To what extent do considerations of identity affect linguistic differences, particularly in an online context? Traditional sociolinguistic approaches lack the data and the methods for asking such detailed questions about language variation and change.\nIn this paper, we show that large-scale social media data can shed new light on how language changes propagate through social networks. We use a data set of Twitter users that contains all public messages for several million accounts, augmented with social network and geolocation metadata. This data set makes it possible to track, and potentially explain, every usage of a linguistic variable as it spreads through social media.

        "evidence": "Quantization of the weights and the activations is a promising technique to save the memory and accelerate the inference speed in deep neural networks (DNNs) which have been getting wider and deeper in recent years. There are two main approaches of the quantization for DNNs (Krishnamoorthi ()): Post-training quantization (PTQ) and quantization-aware training (QAT). In the PTQ, the pre-trained networks are simply quantized without re-training the model. This approach allows us to achieve the nearly floating point accuracy at 8-bits, while below 8-bits, this results in significant accuracy degradation. Although there have been recent attempts to alleviate the accuracy degradation in PTQ;;;), the QAT, where the quantized weights and activations are trained (e.g.,;;), usually leads to better accuracy.\nThe difficulty in QAT is that the weights and the activations are discretized, and intrinsically nondifferentiable. If we take the derivatives forcibly, they either vanish or diverge. To avoid this problem, we replace them with the derivatives of some differentiable function in the backward pass only, called the Straight-Through Estimator (STE);). Since the replacement leads to bias, it is not always possible to learn the network successfully. However this approach can be applied to the low bits below 8-bits with tolerable accuracy degradation;;;).\nOriginally, STE was introduced as the replacement with the derivative of the identity function by.

        "answer": "The classic TextTiling approach.",
        "evidence": "Human-computer dialog/conversation is one of the most challenging problems in artificial intelligence. Given a user-issued utterance (called a query in this paper), the computer needs to provide a reply to the query. In early years, researchers have developed various domain-oriented dialogue systems, which are typically based on rules or templates BIBREF4 , BIBREF5 , BIBREF6 . Recently, open-domain conversation systems have attracted more and more attention in both academia and industry (e.g., XiaoBing from Microsoft and DuMi from Baidu). Due to high diversity, we can hardly design rules or templates in the open domain. Researchers have proposed information retrieval methods BIBREF7 and modern generative neural networks BIBREF8 , BIBREF9 to either search for a reply from a large conversation corpus or generate a new sentence as the reply.\nIn open-domain conversations, context information (one or a few previous utterances) is particularly important to language understanding BIBREF1 , BIBREF9 , BIBREF10 , BIBREF11 . As dialogue sentences are usually casual and short, a single utterance (e.g., “Thank you.” in Figure FIGREF2 ) does not convey much meaning, but its previous utterance (“...writing an essay”) provides useful background information of the conversation. Using such context will certainly benefit the conversation system.\nHowever, tracking all previous utterances as the context is unwise. First, commercial chat-bots usually place high demands on efficiency. In a retrieval-based system, for example, performing a standard process of candidate retrieval and re-ranking for each previous utterance may well exceed the time limit (which is very short, e.g., 500ms). Second, we observe that not all sentences in the current conversation session are equally important. The sentence “Want to take a walk?” is irrelevant to the current context, and should not be considered when the computer synthesizes the reply. Therefore, it raises the question of session segmentation in conversation systems.\nDocument segmentation for general-purpose corpora has been widely studied in NLP. For example, Hearst BIBREF12 proposes the TextTiling approach; she measures the similarity of neighboring sentences based on bag-of-words features, and performs segmentation by thresholding. However, such approaches are not tailored to the dialogue genre and may not be suitable for conversation session segmentation.\nIn this paper, we address the problem of session segmentation for open-domain conversations. We leverage the classic TextTiling approach, but enhance it with modern embedding-based similarity measures. Compared with traditional bag-of-words features, embeddings map discrete words to real-valued vectors, capturing underlying meanings in a continuous vector space; hence, it is more robust for noisy conversation corpora. Further, we propose a tailored method for word embedding learning. In traditional word embedding learning, the interaction between two words in a query and a reply is weaker than that within an utterance. We propose to combine a query and its corresponding reply as a “virtual sentence,” so that it provides a better way of modeling utterances between two agents.\nWe leverage the classic TextTiling approach, but enhance it with modern embedding-based similarity measures.",

Animals featured included meerkats in the Kalahari Desert, American black bears in Minnesota, lions and African bush elephants in East Africa, toque macaques in Sri Lanka, gray whales off the coast of California, polar bears in Svalbard and giant otters in Peru.\n\nThe programme was shown in May 2012 on BBC One in the United Kingdom and was broadcast in 140 countries in total, making it the most ambitious global wildlife series the BBC had ever undertaken. In the US it was retitled 24/7 Wild and aired on NatGeo Wild; in South Africa, Asia, Australia, Italy, Nordic countries, New Zealand and Poland it was shown on BBC Knowledge; and in India on BBC Entertainment.\n\nPlanet Earth II (2016)\nPlanet Earth II is a natural history documentary series, produced by the BBC as a sequel to the highly successful Planet Earth television series, which aired roughly a decade earlier, in 2006. The series was presented and narrated by Sir David Attenborough with the score composed by Hans Zimmer.\n\nThe first trailer was released on 9 October 2016, and the series was broadcast in November 2016 (United Kingdom) on BBC One and BBC One HD. Planet Earth II is also the first television series that the BBC have produced in Ultra-high-definition (4K).\n\nPlanet Earth III (2023)\nPlanet Earth III will be the third part in the Planet Earth trilogy. It is set to release in 2023.",

Isn't it possible that the listener would associate \"pencil\" with \"wood\"? Maybe the listener would associate the word \"pencil\" with \"round\" instead (as pencils are, usually, in fact, round!). Wittgenstein writes regarding several possible \"interpretations\" which may arise after such a lesson. The student may interpret your pointing at a pencil and saying \"pencil\" to mean the following: (1) This is a pencil; (2) This is round; (3) This is wood; (4) This is one; (5) This is hard, etc., etc.",
        "answer": "As example of \"Ostensive defining\" is pointing to an object and saying it's name. Wittgenstein sees \"ostensive defining\" as a problem of communication because simply linking a word to an object carries with it ambiguity. For instance, if someone pointed to a pencil and said, \"pencil\", the listener may not know exactly what the word refers to. It may refer to the pencil itself, the shape of the pencil, the material of the pencil, the quantity of the pencil, or any other quality of the pencil.",

According to BIBREF0, complaint is considered to be a basic speech act used to express negative mismatch between the expectation and reality.

Many transport organizations rely on complaints gathered via these platforms to improve their services, hence understanding these are important for: (1) linguists to identify human expressions of criticism and (2) organizations to improve their query response time and address concerns effectively.\nPresence of inevitable noise, sparse content along with rephrased and structurally morphed instances of posts, make the task at hand difficult BIBREF1. Previous works BIBREF2 in the domain of complaint extraction have focused on static datasets only. These are not robust to changes in the trends reflected, information flow and linguistic variations. We propose an iterative, semi-supervised approach for identification of complaint based tweets, having the ability to be replicated for stream of information flow. The preference of a semi-supervised approach over supervised ones is due to the stated reasons: (a) the task of isolating the training set, make supervised tasks less attractive and impractical and (b) imbalance between the subjective and objective classes lead to poor performance.\nWe propose an iterative, semi-supervised approach for identification of complaint based tweets, having the ability to be replicated for “stream of information flow”.",

Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is animus in consulendo liber (Latin for \"a mind unfettered in deliberation\").\n\nNATO's main headquarters are located in Brussels, Belgium, while NATO's military headquarters are near Mons, Belgium. The alliance has targeted its NATO Response Force deployments in Eastern Europe, and the combined militaries of all NATO members include around 3.5 million soldiers and personnel. Their combined military spending as of 2020 constituted over 57 percent of the global nominal total. Moreover, members have agreed to reach or maintain the target defence spending of at least two percent of their GDP by 2024.\n\nNATO formed with twelve founding members and has added new members nine times, most recently when Finland joined the alliance in April 2023. Following the acceptance of its application for membership in June 2022, Sweden is anticipated to become the 32nd member, with its Accession Protocol to the North Atlantic Treaty now in the process of being ratified by the existing members.

This is a cliché in cartoons and modern theatrics, and it is also used in psychology.\n\nThe common analogy is with the rolling of a snowball down a snow-covered hillside. As it rolls the ball will pick up more snow, gaining more mass and surface area, and picking up even more snow and momentum as it rolls along.\n\nIn aerospace engineering, it is used to describe the multiplication effect in an original weight saving. A reduction in the weight of the fuselage will require less lift, meaning the wings can be smaller. Hence less thrust is required and therefore smaller engines, resulting in a greater weight saving than the original reduction. This iteration can be repeated several times, although the decrease in weight gives diminishing returns.\n\nThe startup process of a feedback electronic oscillator, when power to the circuit is switched on, is a technical application of the snowball effect. Electronic noise is amplified by the oscillator circuit and returned to its input filtered to contain primarily the selected (desired) frequency, gradually getting stronger in each cycle, until a steady-state oscillation is established, when the circuit parameters satisfy the Barkhausen stability criterion.",

        "evidence": "In natural language processing (NLP), question generation is considered to be an important yet challenging problem. Given a passage and answer as inputs to the model, the task is to generate a semantically coherent question for the given answer.\nIn the past, question generation has been tackled using rule-based approaches such as question templates BIBREF0 or utilizing named entity information and predictive argument structures of sentences BIBREF1. Recently, neural-based approaches have accomplished impressive results BIBREF2, BIBREF3, BIBREF4 for the task of question generation. The availability of large-scale machine reading comprehension datasets such as SQuAD BIBREF5, NewsQA BIBREF6, MSMARCO BIBREF7 etc. have facilitated research in question answering task. SQuAD BIBREF5 dataset itself has been the de facto choice for most of the previous works in question generation. However, 90% of the questions in SQuAD can be answered from a single sentence BIBREF8, hence former QG systems trained on SQuAD are not capable of distilling and utilizing information from multiple sentences. Recently released multi-hop datasets such as QAngaroo BIBREF9, ComplexWebQuestions BIBREF10 and HotPotQA BIBREF11 are more suitable for building QG systems that required to gather and utilize information across multiple documents as opposed to a single paragraph or sentence.\nIn multi-hop question answering, one has to reason over multiple relevant sentences from different paragraphs to answer a given question. We refer to these relevant sentences as supporting facts in the context. Hence, we frame Multi-hop question generation as the task of generating the question conditioned on the information gathered from reasoning over all the supporting facts across multiple paragraphs/documents. Since this task requires assembling and summarizing information from multiple relevant documents in contrast to a single sentence/paragraph, therefore, it is more challenging than the existing single-hop QG task. Further, the presence of irrelevant information makes it difficult to capture the supporting facts required for question generation. The explicit information about the supporting facts in the document is not often readily available, which makes the task more complex. In this work, we provide an alternative to get the supporting facts information from the document with the help of multi-task learning. Table TABREF1 gives sample examples from SQuAD and HotPotQA dataset. It is cleared from the example that the single-hop question is formed by focusing on a single sentence/document and answer, while in multi-hop question, multiple supporting facts from different documents and answer are accumulated to form the question.\nMulti-hop QG has real-world applications in several domains, such as education, chatbots, etc. The questions generated from the multi-hop approach will inspire critical thinking in students by encouraging them to reason over the relationship between multiple sentences to answer correctly. Specifically, solving these questions requires higher-order cognitive-skills (e.g., applying, analyzing). Therefore, forming challenging questions is crucial for evaluating a student’s knowledge and stimulating self-learning. Similarly, in goal-oriented chatbots, multi-hop QG is an important skill for chatbots, e.g., in initiating conversations, asking and providing detailed information to the user by considering multiple sources of information. In contrast, in a single-hop QG, only single source of information is considered while generation.\nIn this paper, we propose to tackle Multi-hop QG problem in two stages. In the first stage, we learn supporting facts aware encoder representation to predict the supporting facts from the documents by jointly training with question generation and subsequently enforcing the utilization of these supporting facts. The former is achieved by sharing the encoder weights with an answer-aware supporting facts prediction network, trained jointly in a multi-task learning framework. The latter objective is formulated as a question-aware supporting facts prediction reward, which is optimized alongside supervised sequence loss. Additionally, we observe that multi-task framework offers substantial improvements in the performance of question generation and also avoid the inclusion of noisy sentences information in generated question, and reinforcement learning (RL) brings the complete and complex question to otherwise maximum likelihood estimation (MLE) optimized QG model.\nOur main contributions in this work are: (i). We introduce the problem of multi-hop question generation and propose a multi-task training framework to condition the shared encoder with supporting facts information. (ii). We formulate a novel reward function, multihop-enhanced reward via question-aware supporting fact predictions to enforce the maximum utilization of supporting facts to generate a question; (iii). We introduce an automatic evaluation metric to measure the coverage of supporting facts in the generated question. (iv). Empirical results show that our proposed method outperforms the current state-of-the-art single-hop QG models over several automatic and human evaluation metrics on the HotPotQA dataset.\nOur main contributions in this work are: (i).

To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nWe then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge.",

Then, the absolute approach encodes the remaining length:\nwhere $i=1,\\ldots ,d/2$.\nSimilarly, the relative difference encodes the relative position to the end. This representation is made consistent with the absolute encoding by quantizing the space of the relative positions into a finite set of $N$ integers:\nwhere $q_N: [0, 1] \\rightarrow \\lbrace 0, 1, .., N\\rbrace $ is simply defined as $q_N(x) = \\lfloor {x \\times N}\\rfloor $.

We prefer a representation based on BPE, unlike BIBREF11, as it leads to better translations with less training time BIBREF18, BIBREF19.

In 2013, Smithsonian named one local chili parlor one of the \"20 Most Iconic Food Destinations in America\". Its name evokes comparison to chili con carne, but the two are dissimilar in consistency, flavor, and serving method; Cincinnati chili more closely resembles Greek pasta sauces and spiced-meat hot dog topping sauces seen in other parts of the United States.\n\nIngredients include ground beef, water or stock, tomato paste, spices such as cinnamon, nutmeg, allspice, clove, cumin, chili powder, bay leaf, and in some home recipes unsweetened dark chocolate in a soupy consistency. Customary toppings include cheddar cheese, onions, and beans; specific combinations of toppings are known as \"ways\". The most popular order is a \"three-way\", which adds shredded cheese to the chili-topped spaghetti (a \"two-way\"), while a \"four-way\" or \"five-way\" adds onions and/or beans before topping with the cheese. Ways are often served with oyster crackers and a mild hot sauce. Cincinnati chili is almost never served or eaten by the bowl.\n\nWhile served in many local restaurants, it is most often associated with the over 250 independent and chain \"chili parlors\" (restaurants specializing in Cincinnati chili) found throughout greater Cincinnati with franchise locations throughout Ohio and in Kentucky, Indiana, Florida, and the Middle East.

Opponents on either side of the net hit the ball back and forth until one side commits a rule infraction. Pickleball was invented in 1965 as a children's backyard game on Bainbridge Island, Washington, US. In 2022, pickleball was adopted as the official state sport of Washington.\n\nThe appearance of a pickleball court, and the manner of play, resembles tennis, but the court is the size of a doubles badminton court, less than a third the size of a tennis court. Court lines and rules are specific to pickleball and include two 7-foot areas (2.1 m) on either side of the net known as the non-volley zones, where the ball cannot be hit with the paddle unless the ball bounces first. The official rules specify side-out scoring, where only the serving team can score a point. All serves are made with an underhand stroke. The hard plastic ball used in pickleball produces significantly less bounce than softer flexible balls, such as a tennis ball. The minimal bounce combined with the non-volley zone and underhand serve give the game dynamic pace and strategy ranging from soft dink shots that stay within the two non-volley zones to powerful drive shots and overhead smash shots. To minimize any advantage the serving or receiving side might have at the beginning of the game, the ball must bounce once on each side of the net before either team may volley the ball, which is to hit the ball in the air before it bounces.\n\nBetween 1965 and 2020, it became a popular sport in the US Pacific Northwest, and in the meantime began to grow elsewhere. In 2021, 2022 and 2023, the sport was named the fastest-growing sport in the United States by the Sports and Fitness Industry Association, with over 4.8 million players. A growing interest in the sport is attributed to several factors, including a short learning curve, appeal to a wide range of ages and fitness levels, and low startup costs. There are now thousands of pickleball tournaments throughout the United States, including the US National Championships and the U.S. Open Tournament, along with two professional tours and one professional league.

In 2014 the record for the largest chain was broken again by a swap involving 70 participants. The acceptance of altruistic donors has enabled chains of transplants to form. Kidney chains are initiated when an altruistic donor donates a kidney to a patient who has a willing but incompatible donor. This incompatible donor then 'pays it forward' and passes on the generosity to another recipient who also had a willing but incompatible donor. Michael Rees from the University of Toledo developed the concept of open-ended chains. This was a variation of a concept developed at Johns Hopkins University. On 30 July 2008, an altruistic donor kidney was shipped via commercial airline from Cornell to UCLA, thus triggering a chain of transplants.

        "answer": "They first train a high-resource language pair, then use the resulting trained network (the parent model) to initialize and constrain training for our low-resource language pair (the child model).",
        "evidence": "Neural machine translation (NMT) BIBREF0 is a promising paradigm for extracting translation knowledge from parallel text. NMT systems have achieved competitive accuracy rates under large-data training conditions for language pairs such as English-French. However, neural methods are data-hungry and learn poorly from low-count events. This behavior makes vanilla NMT a poor choice for low-resource languages, where parallel data is scarce. Table 1 shows that for 4 low-resource languages, a standard string-to-tree statistical MT system (SBMT) BIBREF1 , BIBREF2 strongly outperforms NMT, even when NMT uses the state-of-the-art local attention plus feed-input techniques from luong2015effective.\nIn this paper, we give a method for substantially improving NMT results on these languages. Neural models learn representations of their input that are often useful across tasks. Our key idea is to first train a high-resource language pair, then use the resulting trained network (the parent model) to initialize and constrain training for our low-resource language pair (the child model). We find that we can optimize our results by fixing certain parameters of the parent model, letting the rest be fine-tuned by the child model. We report NMT improvements from transfer learning of 5.6 Bleu on average, and we provide an analysis of why the method works. The final NMT system approaches strong SBMT baselines in in all four language pairs, and exceeds SBMT performance in one of them. Furthermore, we show that NMT is an exceptional re-scorer of `traditional' MT output; even NMT that on its own is worse than SBMT is consistently able to improve upon SBMT system output when incorporated as a re-scoring model.\nWe start by a brief description of our NMT model in Section \"NMT Background\" . Section \"Transfer Results\" gives some background on transfer learning and explains how we use it to improve machine translation performance. Our main experiments translating Hausa, Turkish, Uzbek and Urdu into English with the help of a French-English parent model are presented in Section \"Experiments\" . Section \"Analysis\" explores alternatives to our model to enhance understanding. We find that the choice of parent language pair affects performance, and provide an empirical upper bound on transfer performance using an artificial language. We experiment with English-only language models, copy models, and word-sorting models to show that what we transfer goes beyond monolingual information and using a translation model trained on bilingual corpora as a parent is essential. We show the effects of freezing, fine-tuning, and smarter initialization of different components of the attention-based NMT system during transfer. We compare the learning curves of transfer and no-transfer models showing that transfer solves an overfitting problem, not a search problem. We summarize our contributions in Section \"Conclusion\" .\nIn this paper, we give a method for substantially improving NMT results on these languages.

        "evidence": "Low dimensional word representations (embeddings) have become a key component in modern NLP systems for language modeling, parsing, sentiment classification, and many others. These embeddings are usually derived by employing the distributional hypothesis: that similar words appear in similar contexts BIBREF0 .\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix BIBREF1 . The most well-known predictive model, which has become eponymous with word embedding, is word2vec BIBREF2 . Popular counting models include PPMI-SVD BIBREF3 , GloVe BIBREF4 , and LexVec BIBREF5 .\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.\nfastText BIBREF6 addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors. This addresses both issues above as learned information is shared through the n-gram vectors and from these OOV word representations can be constructed.\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , but the method proposed here should transfer to GloVe unchanged.\nThe LexVec objective is modified such that a word's vector is the sum of all its subword vectors.\nWe compare 1) the use of n-gram subwords, like fastText, and 2) unsupervised morphemes identified using Morfessor BIBREF11 to learn whether more linguistically motivated subwords offer any advantage over simple n-grams.\nTo evaluate the impact subword information has on in-vocabulary (IV) word representations, we run intrinsic evaluations consisting of word similarity and word analogy tasks. The incorporation of subword information results in similar gains (and losses) to that of fastText over Skip-gram. Whereas incorporating n-gram subwords tends to capture more syntactic information, unsupervised morphemes better preserve semantics while also improving syntactic results. Given that intrinsic performance can correlate poorly with performance on downstream tasks BIBREF12 , we also conduct evaluation using the VecEval suite of tasks BIBREF13 , in which\nall subword models, including fastText, show no significant improvement over word-level models.\nWe verify the model's ability to represent OOV words by quantitatively evaluating nearest-neighbors. Results show that, like fastText, both LexVec n-gram and (to a lesser degree) unsupervised morpheme models give coherent answers.\nThis paper discusses related word ( $§$ \"Related Work\" ), introduces the subword LexVec model ( $§$ \"Subword LexVec\" ), describes experiments ( $§$ \"Materials\" ), analyzes results ( $§$ \"Results\" ), and concludes with ideas for future works ( $§$ \"Conclusion and Future Work\" ).\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations (Salleet al., 2016a; Cer et al., 2017; Wohlgenannt et al., 2017; Konkol et al., 2017), but the method proposed here should transfer to GloVe unchanged.",

There are many different reasons that people decide to pursue getting their pilot's license including the challenge of learning a new skill, having the ability to travel by private plane for business or pleasure, sightseeing, or as a career option.  The process of learning to fly and getting your license requires several steps and usually takes about a year to complete.  The first step is to research local flight schools and potentially do a discovery flight with a flight instructor to see if you enjoy it before committing the time and money.  Should you decide to pursue it, you'll need to find and go to an Aviation Medical Examiner to get checked-out and have a student pilot and medical certificate issued.  Once you've completed that you can begin your training which will include both ground school and flight school.  The next step is to purchase the necessary books, study sufficiently and prepare to take an FAA written exam.  While you're studying, you'll begin your flight training which requires a minimum of 40 hours of flying, however most individuals end-up flying between 60 - 75 hours.  When your instructor feels you're able to demonstrate mastery of all of the required skills and are able to make sound decisions, you'll be ready to take a practical exam with either an FAA examiner or a designated examiner.   Upon successful completion of your test, you'll be issued your pilots license and be ready to take up passengers.  On average, the cost to get your pilot's license ranges from $8,000 to $12,000.  This may sound expensive, but it's worth it to have a skill that you can enjoy for a lifetime.",

        "question": "Is the task done on structured data only?",
        "answer": "Yes.",
        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nHowever, these works deal with unstructured data (sentences at the higher level and words at a lower level) as opposed to structured data in our case.",

        "answer": "Dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network.",
        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network.",

        "answer": "These examples illustrate the difficulties of UTD: it does not match the full audio, and it incorrectly clusters part of utterance B with a good pair in C and D.",
        "evidence": "For UTD we use the Zero Resource Toolkit (ZRTools; Jansen and Van Durme, 2011). ZRTools uses dynamic time warping (DTW) to discover pairs of acoustically similar audio segments, and then uses graph clustering on overlapping pairs to form a hard clustering of the discovered segments. Replacing each discovered segment with its unique cluster label, or pseudoterm, gives us a partial, noisy transcription, or pseudotext (Fig. FIGREF4 ).\nIn creating a translation model from this data, we face a difficulty that does not arise in the parallel texts that are normally used to train translation models: the pseudotext does not represent all of the source words, since the discovered segments do not cover the full audio (Fig. FIGREF4 ). Hence we must not assume that our MT model can completely recover the translation of a test sentence. In these conditions, the language modeling and ordering assumptions of most MT models are unwarranted, so we instead use a simple bag-of-words translation model based only on co-occurrence: IBM Model 1 BIBREF11 with a Dirichlet prior over translation distributions, as learned by fast_align BIBREF12 . In particular, for each pseudoterm, we learn a translation distribution over possible target words. To translate a pseudoterm in test data, we simply return its highest-probability translation (or translations, as discussed in § SECREF5 ).\nThis setup implies that in order to translate, we must apply UTD on both the training and test audio. Using additional (not only training) audio in UTD increases the likelihood of discovering more clusters. We therefore generate pseudotext for the combined audio, train the MT model on the pseudotext of the training audio, and apply it to the pseudotext of the test data. This is fair since the UTD has access to only the audio.\nExample utterances from our data, showing UTD matches, corresponding pseudotext, and English translation. For clarity, we also show Spanish transcripts with the approximate alignment of each pseudoterm underlined, though these transcripts are unavailable to our system. Stopwords (in gray) are ignored in our evaluations. These examples illustrate the difficulties of UTD: it does not match the full audio, and it incorrectly clusters part of utterance B with a good pair in C and D.",

        "answer": "By using a combinational ranking function.",
        "evidence": "Knowledge-based question answering (KBQA) aims to answer natural language questions over knowledge bases (KBs) such as DBpedia and Freebase. Formal query generation is an important component in many KBQA systems BIBREF0 , BIBREF1 , BIBREF2 , especially for answering complex questions. Given entity and relation linking results, formal query generation aims to generate correct executable queries, e.g., SPARQL queries, for the input natural language questions. An example question and its formal query are shown in Figure FIGREF1 . Generally speaking, formal query generation is expected to include but not be limited to have the capabilities of (i) recognizing and paraphrasing different kinds of constraints, including triple-level constraints (e.g., “movies\" corresponds to a typing constraint for the target variable) and higher level constraints (e.g., subgraphs). For instance, “the same ... as\" represents a complex structure shown in the middle of Figure FIGREF1 ; (ii) recognizing and paraphrasing aggregations (e.g., “how many\" corresponds to Count); and (iii) organizing all the above to generate an executable query BIBREF3 , BIBREF4 .\nThere are mainly two kinds of query generation approaches for complex questions. (i) Template-based approaches choose a pre-collected template for query generation BIBREF1 , BIBREF5 . Such approaches highly rely on the coverage of templates, and perform unstably when some complex templates have very few natural language questions as training data. (ii) Approaches based on semantic parsing and neural networks learn entire representations for questions with different query structures, by using a neural network following the encode-and-compare framework BIBREF2 , BIBREF4 . They may suffer from the lack of training data, especially for long-tail questions with rarely appeared structures. Furthermore, both above approaches cannot handle questions with unseen query structures, since they cannot generate new query structures.\nTo cope with the above limitations, we propose a new query generation approach based on the following observation: the query structure for a complex question may rarely appear, but it usually contains some substructures that frequently appeared in other questions. For example, the query structure for the question in Figure FIGREF1 appears rarely, however, both “how many movies\" and “the same ... as\" are common expressions, which correspond to the two query substructures in dashed boxes. To collect such frequently appeared substructures, we automatically decompose query structures in the training data. Instead of directly modeling the query structure for the given question as a whole, we employ multiple neural networks to predict query substructures contained in the question, each of which delivers a part of the query intention. Then, we select an existing query structure for the input question by using a combinational ranking function. Also, in some cases, no existing query structure is appropriate for the input question. To cope with this issue, we merge query substructures to build new query structures.

        "answer": "It can help enrich the human-like conversation with artificial intelligence (AI).",
        "evidence": "The advent of smart agents such as Amazon Echo and Google Home has shown relatively wide market adoption. Users have been familiarized with formulating questions and orders in a way that these agents can easily comprehend and take actions. Given this trend, particularly for cases where questions can have various forms such as yes/no, alternative, wh-, echo and embedded BIBREF0, a number of analysis techniques have been studied in the domain of semantic role labeling BIBREF1 and entity recognition BIBREF2. Nowadays, various question answering tasks have been proposed BIBREF3 and have yielded systems that have demonstrated significant advances in performance. Studies on the parsing of canonical imperatives BIBREF4 have also been done for many household agents.\nHowever, discerning the intent from a conversational and non-canonical sentence (question or command) and extracting its intent argument is still a challenge. Additional complexity is introduced when the target text is in a speech recognition context, as the result may not contain punctuation. For example, given an unclear declarative question BIBREF5 such as “poppa joe you want me to go now”, a human listener can interpret the question as `if Joe wants the speaker to go now', but this can be challenging to for a machine. Also, sometimes, merely the speech act can be hard to guess from the sentence form, as in inferring “why don't you just call the police” as a representation of the to-do list `to call the police' (Figure 1). Although many advanced dialog managing systems may generate a plausible reaction to the input utterances, it is different from extracting the exact intent argument (a question set or a to-do-list) that should be investigated for an actual operation.\nComplexities like the example discussed above have not seen much exploration outside of English, especially in the context of languages with a distinguished syntax or cases which do not use Latin-like alphabets. As a more concrete example, in the Korean language, the morphology is agglutinative, the syntax is head-final, and scrambling (non-deterministic permutations of word/phrase ordering) is a common practice between native speakers. Specifically, the agglutinative property of Korean requires additional morphological analysis, which makes it challenging to identify the component of the sentence that has the strongest connection to core intent. Additionally, the head-finality characteristic introduces an additional layer of complexity, where an under-specified sentence ender incorporates a prosodic cue which requires disambiguation to comprehend the original intent BIBREF6, BIBREF7. Finally, considering the scrambling aspect, which frequently happens in spoken utterances, further analysis is required on top of recognizing the entities and extracting the relevant phrases. This makes it difficult for dialog managers to directly apply conventional analysis methods that have been used in Germanic or other Indo-European languages.\nIn this paper, we explore these aspects in the context of Korean, a less explored, low-resource language with various non-canonical expressions. From there on, we propose a structured sentence annotation scheme which can help enrich the human-like conversation with artificial intelligence (AI). For the automation, we annotate an existing corpus and then augment the dataset to mitigate class imbalance, demonstrating the flexibility, practicality, and extensibility of the proposed methods. To further prove that the scheme is not limited to Korean, we demonstrate the methodology using English examples and supplement specific cases with Korean. To begin with, in section 2, we present the theoretical background of this study. We then discuss the detailed procedure with examples, along with an explanation of how it fits with modern natural language understanding (NLU) systems and an evaluation framework.\nFrom there on, we propose a structured sentence annotation scheme which can help enrich the human-like conversation with artificial intelligence (AI).",

        "evidence": "Deep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available. However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nOur proposed system consists of three stages.

Under such conditions, it may prove difficult to draw firm conclusions about which keyphrase extraction model performs best, as the impact of preprocessing on overall performance cannot be properly quantified.\nWhile previous work clearly states that efficient document preprocessing is a prerequisite for the extraction of high quality keyphrases, there is, to our best knowledge, no empirical evidence of how preprocessing affects keyphrase extraction performance. In this paper, we re-assess the performance of several state-of-the-art keyphrase extraction models at increasingly sophisticated levels of preprocessing. Three incremental levels of document preprocessing are experimented with: raw text, text cleaning through document logical structure detection, and removal of keyphrase sparse sections of the document.

In Example 2, “UTF8min新生児” (newborn infant) and “UTF8min30歳以上の” (of 30 ‐ year ‐ old or more) are repeated in the output of baseline-NMT, but they appear only once in the output of encoder-decoder-reconstructor.\nIn addition, Figures FIGREF25 and FIGREF25 show the attention layer on baseline-NMT and encoder-decoder-reconstructor in each example. In Figure FIGREF25 , although the attention layer of baseline NMT attends input word “turbulent”, the decoder does not output “UTF8min乱流” (turbulent) but “UTF8min検討” (examined) at the 13th word. Thus, under-translation may be resulted from the hidden layer or the embedding layer instead of the attention layer. In Figure FIGREF25 , it is found that the attention layer of baseline-NMT repeatedly attends input words “newborn infant” and “30 ‐ year ‐ old or more”. Consequently, the decoder repeatedly outputs “UTF8min新生児” (newborn infant) and “UTF8min30歳以上の” (of 30 ‐ year ‐ old or more). On the other hand, the attention layer of encoder-decoder-reconstructor almost correctly attends input words.\nTable TABREF28 shows a comparison of the number of word occurrences for each corpus and model. The columns show (i) the number of words that appear more frequently than the counterparts in the reference, and (ii) the number of words that appear more than once but are not included in the reference. Note that these numbers do not include unknown words, so (iii) shows the number of unknown words. In all the cases, the number of occurrence of redundant words is reduced in encoder-decoder-reconstructor. Thus, we confirmed that encoder-decoder-reconstructor achieves reduction of repeating and missing words while maintaining the quality of translation.\nIn all the cases, the number of occurrence of redundant words is reduced in encoder-decoder-reconstructor. Thus, we confirmed that encoder-decoder-reconstructor achieves reduction of repeating and missing words while maintaining the quality of translation.",

Newsbusters takes a different track: the opening paragraph conveys an overall negative perspective on the March for Science, despite its neutral language, but it achieves this by contrasting general interest in the march with a claimed negative view of the march by many “actual scientists.” On the other hand, the New York Times points to an important and presumably positive outcome of the march, despite its controversiality: a renewed look into the role of science in public life and politics. Like Newsbusters, it lacks any explicit evaluative language and relies on the structural relations between events to convey an overall positive perspective; it contrasts the controversy surrounding the march with a claim that the march has triggered an important discussion, which is in turn buttressed by the reporter's mentioning of the responses of the Times' readership.\nWhich events authors choose to include in their history, which they leave out, and the way the events chosen relate to the march are crucial factors in conveying bias.",

She is often shown in the midst of her war with Mahishasura, the buffalo demon, at the time she victoriously kills the demonic force. Her icon shows her in action, yet her face is calm and serene. In Hindu arts, this tranquil attribute of Durga's face is traditionally derived from the belief that she is protective and violent not because of her hatred, egotism or getting pleasure in violence, but because she acts out of necessity, for the love of the good, for liberation of those who depend on her, and a mark of the beginning of soul's journey to creative freedom.\n\nDurga traditionally holds the weapons of various male gods of Hindu mythology, which they give her to fight the evil forces because they feel that she is shakti (energy, power).

These weapons are considered symbolic by Shakta Hindus, representing self-discipline, selfless service to others, self-examination, prayer, devotion, remembering her mantras, cheerfulness and meditation.

A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells.

        "answer": "The two-layer LSTM is trained on German Wikipedia text.",
        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus.",

        "question": "What was the Bismarck battleship?",
        "evidence": "Bismarck was the first of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine. Named after Chancellor Otto von Bismarck, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.\n\nIn the course of the warship's eight-month career, Bismarck conducted only one offensive operation that lasted 8 days in May 1941, codenamed Rheinübung. The ship, along with the heavy cruiser Prinz Eugen, was to break into the Atlantic Ocean and raid Allied shipping from North America to Great Britain. The two ships were detected several times off Scandinavia, and British naval units were deployed to block their route. At the Battle of the Denmark Strait, the battlecruiser HMS Hood initially engaged Prinz Eugen, probably by mistake, while HMS Prince of Wales engaged Bismarck. In the ensuing battle Hood was destroyed by the combined fire of Bismarck and Prinz Eugen, which then damaged Prince of Wales and forced her retreat. Bismarck suffered sufficient damage from three hits by Prince of Wales to force an end to the raiding mission.\n\nThe destruction of Hood spurred a relentless pursuit by the Royal Navy involving dozens of warships. Two days later, heading for occupied France to effect repairs, Bismarck was attacked by fifteen Fairey Swordfish torpedo bombers from the aircraft carrier HMS Ark Royal; one scored a hit that rendered the battleship's steering gear inoperable. In her final battle the following morning, the already-crippled Bismarck was engaged by two British battleships and two heavy cruisers, and sustained incapacitating damage and heavy loss of life. The ship was scuttled to prevent her being boarded by the British, and to allow the ship to be abandoned so as to limit further casualties. Most experts agree that the battle damage would have caused her to sink eventually.\n\nThe wreck was located in June 1989 by Robert Ballard, and has since been further surveyed by several other expeditions.",

Additionally, playing volleyball in the sand is way more difficult and a harder workout than playing on a court. In order to jump the same height or run after a shanked ball, you have to exert more energy.

Arab-tweet is a tweet dataset of 11 Arabic regions from 17 different countries. For each region, data from 100 Twitter users were crawled. Users needed to have posted at least 2,000 and were selected based on an initial list of seed words characteristic of each region. The seed list included words such as <برشة> /barsha/ ‘many’ for Tunisian Arabic and <وايد> /wayed/ ‘many’ for Gulf Arabic. BIBREF19 employed human annotators to verify that users do belong to each respective region. Annotators also assigned gender labels from the set male, female and age group labels from the set under-25, 25-to34, above-35 at the user-level, which in turn is assigned at tweet level. Tweets with less than 3 words and re-tweets were removed. Refer to BIBREF19 for details about how annotation was carried out. We provide a description of the data in Table TABREF10. Table TABREF10 also provides class breakdown across our splits.We note that BIBREF19 do not report classification models exploiting the data.\nUBC Twitter Gender Dataset. We also develop an in-house Twitter dataset for gender. We manually labeled 1,989 users from each of the 21 Arab countries. The data had 1,246 “male\", 528 “female\", and 215 unknown users. We remove the “unknown\" category and balance the dataset to have 528 from each of the two `male\" and “female\" categories. We ended with 69,509 tweets for `male\" and 67,511 tweets for “female\". We split the users into 80% TRAIN set (110,750 tweets for 845 users), 10% DEV set (14,158 tweets for 106 users), and 10% TEST set (12,112 tweets for 105 users). We, then, model this dataset with BERT-Base, Multilingual Cased model and evaluate on development and test sets. Table TABREF15 shows that fine-tuned model obtains 62.42% acc on DEV and 60.54% acc on TEST.\nThe dialect identification model in AraNet is based on our winning system in the MADAR shared task 2 BIBREF20 as described in BIBREF12. The corpus is divided into train, dev and test, and the organizers masked test set labels. We lost some tweets from training data when we crawled using tweet ids, ultimately acquiring 2,036 (TRAIN-A), 281 (DEV) and 466 (TEST). We also make use of the task 1 corpus (95,000 sentences BIBREF21). More specifically, we concatenate the task 1 data to the training data of task 2, to create TRAIN-B. Again, note that TEST labels were only released to participants after the official task evaluation. Table TABREF17 shows statistics of the data. We used tweets from 21 Arab countries as distributed by task organizers, except that we lost some tweets when we crawled using tweet ids. We had 2,036 (TRAIN-A), 281 (DEV) and 466 (TEST). For our experiments, we also make use of the task 1 corpus (95,000 sentences BIBREF21). More specifically, we concatenate the task 1 data to the training data of task 2, to create TRAIN-B. Note that both DEV and TEST across our experiments are exclusively the data released in task 2, as described above. TEST labels were only released to participants after the official task evaluation. Table TABREF17 shows statistics of the data. More information about the data is in BIBREF21. We use TRAIN-A to perform supervised modeling with BERT and TRAIN-B for self training, under various conditions. We refer the reader to BIBREF12 for more information about our different experimental settings on dialect id. We acquire our best results with self-training, with a classification accuracy of 49.39% and F1 score at 35.44. This is the winning system model in the MADAR shared task and we showed in BIBREF12 that our tweet-level predictions can be ported to user-level prediction. On user-level detection, our models perform superbly, with 77.40% acc and 71.70% F1 score on unseen MADAR blind test data.\nData and Models ::: Emotion\nWe make use of two datasets, the LAMA-DINA dataset from BIBREF22, a Twitter dataset with a combination of gold labels from BIBREF23 and distant supervision labels. The tweets are labeled with the Plutchik 8 primary emotions from the set: {anger, anticipation, disgust, fear, joy, sadness, surprise, trust}. The distant supervision approach depends on use of seed phrases with the Arabic first person pronoun انا> (Eng. “I\") + a seed word expressing an emotion, e.g., فرحان> (Eng. “happy\"). The manually labeled part of the data comprises tweets carrying the seed phrases verified by human annotators $9,064$ tweets for inclusion of the respective emotion. The rest of the dataset is only labeled using distant supervision (LAMA-DIST) ($182,605$ tweets) . For more information about the dataset, readers are referred to BIBREF22. The data distribution over the emotion classes is in Table TABREF20. We combine LAMA+DINA and LAMA-DIST training set and refer to this new training set as LAMA-D2 (189,903 tweets). We fine-tune BERT-Based, Multilingual Cased on the LAMA-D2 and evaluate the model with same DEV and TEST sets from LAMA+DINA. On DEV set, the fine-tuned BERT model obtains 61.43% on accuracy and 58.83 on $F_1$ score. On TEST set, we acquire 62.38% acc and 60.32% $F_1$ score.\nWe use the dataset for irony identification on Arabic tweets released by IDAT@FIRE2019 shared-task BIBREF24. The shared task dataset contains 5,030 tweets related to different political issues and events in the Middle East taking place between 2011 and 2018. Tweets are collected using pre-defined keywords (i.e., targeted political figures or events) and the positive class involves ironic hashtags such as #sokhria, #tahakoum, and #maskhara (Arabic variants for “irony\"). Duplicates, retweets, and non-intelligible tweets are removed by organizers. Tweets involve both MSA as well as dialects at various degrees of granularity such as Egyptian, Gulf, and Levantine.\nWe collect 15 datasets related to sentiment analysis of Arabic, including MSA and dialects BIBREF25, BIBREF26, BIBREF27, BIBREF1, BIBREF28, BIBREF29, BIBREF30, BIBREF31, BIBREF32, BIBREF33, BIBREF34. Table TABREF28 shows all the corpora we use. These datasets involve different types of sentiment analysis tasks such as binary classification (i.e., negative or positive), 3-way classification (i.e., negative, neutral, or positive), and subjective language detection. To combine these datasets for binary sentiment classification, we normalize different types of label to binary labels in the set $\\lbrace `positive^{\\prime }, `negative^{\\prime }\\rbrace $ by following rules:\nFor modeling age and gender, we use Arap-Tweet BIBREF19 , which we will refer to as Arab-Tweet.\nUBC Twitter Gender Dataset.

        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nWe evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR (Dettmers et al., 2018) and FB15k-237 (Toutanova and Chen, 2015).",

        "evidence": "Humor recognition refers to the task of deciding whether a sentence/spoken-utterance expresses a certain degree of humor. In most of the previous studies BIBREF1 , BIBREF2 , BIBREF3 , humor recognition was modeled as a binary classification task. In the seminal work BIBREF1 , a corpus of INLINEFORM0 “one-liners\" was created using daily joke websites to collect humorous instances while using formal writing resources (e.g., news titles) to obtain non-humorous instances. Three humor-specific stylistic features, including alliteration, antonymy, and adult slang were utilized together with content-based features to build classifiers. In a recent work BIBREF3 , a new corpus was constructed from the Pun of the Day website. BIBREF3 explained and computed latent semantic structure features based on the following four aspects: (a) Incongruity, (b) Ambiguity, (c) Interpersonal Effect, and (d) Phonetic Style. In addition, Word2Vec BIBREF4 distributed representations were utilized in the model building.\nBeyond lexical cues from text inputs, other research has also utilized speakers' acoustic cues BIBREF2 , BIBREF5 . These studies have typically used audio tracks from TV shows and their corresponding captions in order to categorize characters' speaking turns as humorous or non-humorous. Utterances prior to canned laughter that was manually inserted into the shows were treated as humorous, while other utterances were treated as negative cases.\nConvolutional Neural Networks (CNNs) have recently been successfully used in several text categorization tasks (e.g., review rating, sentiment recognition, and question type recognition). Kim2014,Johnson2015,Zhang2015 suggested that using a simple CNN setup, which entails one layer of convolution on top of word embedding vectors, achieves excellent results on multiple tasks. Deep learning recently has been applied to computational humor research BIBREF5 , BIBREF6 . In Bertero2016LREC, CNN was found to be the best model that uses both acoustic and lexical cues for humor recognition. By using Long Short Time Memory (LSTM) cells BIBREF7 , Bertero2016NAACL showed that Recurrent Neural Networks (RNNs) perform better on modeling sequential information than Conditional Random Fields (CRFs) BIBREF8 .\nFrom the brief review, it is clear that corpora used in humor research so far are limited to one-line puns or jokes and conversations from TV comedy shows. There is a great need for an open corpus that can support investigating humor in presentations. CNN-based text categorization methods have been applied to humor recognition (e.g., in BIBREF5 ) but with limitations: (a) a rigorous comparison with the state-of-the-art conventional method examined in yang-EtAl:2015:EMNLP2 is missing; (b) CNN's performance in the previous research is not quite clear; and (c) some important techniques that can improve CNN performance (e.g., using varied-sized filters and dropout regularization BIBREF10 ) were not applied. Therefore, the present study is meant to address these limitations.\nBy using Long Short Time Memory (LSTM) cells (Hochreiter and Schmidhuber, 1997), Bertero and Fung (2016a) showed that Recurrent Neural Networks (RNNs) perform better on modeling sequential information than Conditional Random Fields (CRFs) (Lafferty et al., 2001).",

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nThe viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.",

        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nThe goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task).",

Held out sets are constructed using the following procedure: We traverse over the collections and for every discovered equation we randomly sample words from its context set. The held out set contains the sampled words and their context window which also includes the equation. For each held out word we also generate a set of negative samples for the given word context. We perform the same procedure to form a validation set. For each of the INLINEFORM0 equations in a collection, two held out words INLINEFORM1 are sampled. For a context window of size 4 the sampled word context is defined as INLINEFORM2 .\nDuring training we compute the predictive log-likelihood on the validation set of words using the fitted model after each iteration over the collection. A fitted model is a collection of interaction and feature vectors for each equation and word. Given a fitted model, the log probability of a held out word is computed using the following formula: DISPLAYFORM0 \nwhich is the softmax function computed over a set of negative samples INLINEFORM0 and the held out word. In particular, we ran the model 20 times across the collection. After each collection iteration INLINEFORM1 we observe whether the predictive log-likelihood continues to improve compared to the previous ( INLINEFORM2 ) iteration. We stop at the INLINEFORM3 -th iteration when that is no longer the case.\nWhen modeling equations using EqEmb we perform two passes over the collection. In the first pass we only model words while ignoring equations. In the second pass we only model equations while holding fixed the interaction and feature vectors of all words. In context of EqEmb we treat equations as singleton words and the broader question that we are trying to answer is whether we can learn something about the meaning of the singleton words given the fixed word interaction and feature vectors.\nIn our analysis we evaluated the performance of the EqEmb models across different sizes for the word context (W), word-equation context (E) and embedding vector size (K). Model performance was compared with 4 existing embedding models: b-emb, CBOW, GloVe and PV-DM. We used the gensim BIBREF13 implementation of the CBOW and PV-DM models. When modeling equations using the first 3 embedding models we treat equations as regular words in the collection.

Then we estimate the probability of a word by DISPLAYFORM0 \nThe goal of word embedding learning is to maximize the average probability of all words (suppose we have INLINEFORM0 running words): DISPLAYFORM0 \nWe used hierarchical softmax to approximate the probability.\nTo model the context, we further adopt the continuous bag-of-words (CBOW) method. The context is defined by the sum of neighboring words' (input) vectors in a fixed-size window ( INLINEFORM0 to INLINEFORM1 ) within a sentence: DISPLAYFORM0 \nNotice that the context vector INLINEFORM0 in Equation ( EQREF12 ) and the output vector INLINEFORM1 in Equation ( EQREF9 ) are different as suggested in BIBREF25 , BIBREF26 , but the details are beyond the scope of our paper.\nVirtual Sentences\nIn a conversation corpus, successive sentences have a stronger interaction than general texts. For example, in Figure FIGREF2 , the words thank and welcome are strongly correlated, but they hardly appear in the a sentence and thus a same window. Therefore, traditional within-sentence CBOW may not capture the interaction between a query and its corresponding reply.\nIn this paper, we propose the concept of virtual sentences to learn word embeddings for conversation data. We concatenate a query INLINEFORM0 and its reply INLINEFORM1 as a virtual sentence INLINEFORM2 . We also use all words (other than the current one) in the virtual sentence as context (Figure 2). Formally, the context INLINEFORM3 of the word INLINEFORM4 is given by DISPLAYFORM0 \nIn this way, related words across two successive utterances from different agents can have interaction during word embedding learning. As will be shown in Subsection SECREF22 , virtual sentences yield a higher performance for dialogue segmentation.\nTo train the embeddings, we adopt the word2vec approach.",

        "evidence": "According to Anglo-American property law, a mortgage occurs when an owner (usually of a fee simple interest in realty) pledges his or her interest (right to the property) as security or collateral for a loan. Therefore, a mortgage is an encumbrance (limitation) on the right to the property just as an easement would be, but because most mortgages occur as a condition for new loan money, the word mortgage has become the generic term for a loan secured by such real property. As with other types of loans, mortgages have an interest rate and are scheduled to amortize over a set period of time, typically 30 years. All types of real property can be, and usually are, secured with a mortgage and bear an interest rate that is supposed to reflect the lender's risk.\n\nMortgage lending is the primary mechanism used in many countries to finance private ownership of residential and commercial property (see commercial mortgages). Although the terminology and precise forms will differ from country to country, the basic components tend to be similar:\n\nProperty: the physical residence being financed. The exact form of ownership will vary from country to country and may restrict the types of lending that are possible.\nMortgage: the security interest of the lender in the property, which may entail restrictions on the use or disposal of the property. Restrictions may include requirements to purchase home insurance and mortgage insurance, or pay off outstanding debt before selling the property.\nBorrower: the person borrowing who either has or is creating an ownership interest in the property.\nLender: any lender, but usually a bank or other financial institution. (In some countries, particularly the United States, Lenders may also be investors who own an interest in the mortgage through a mortgage-backed security. In such a situation, the initial lender is known as the mortgage originator, which then packages and sells the loan to investors. The payments from the borrower are thereafter collected by a loan servicer.)\nPrincipal: the original size of the loan, which may or may not include certain other costs; as any principal is repaid, the principal will go down in size.\nInterest: a financial charge for use of the lender's money.\nForeclosure or repossession: the possibility that the lender has to foreclose, repossess or seize the property under certain circumstances is essential to a mortgage loan; without this aspect, the loan is arguably no different from any other type of loan.\nCompletion: legal completion of the mortgage deed, and hence the start of the mortgage.\nRedemption: final repayment of the amount outstanding, which may be a \"natural redemption\" at the end of the scheduled term or a lump sum redemption, typically when the borrower decides to sell the property. A closed mortgage account is said to be \"redeemed\".",

We compare: (i) a single-task model for constituency parsing and another one for dependency parsing, (ii) a multi-task model for constituency parsing (and another for dependency parsing) where each element of the 3-tuple is predicted as a partial label in a separate subtask instead of as a whole, (iii) different mtl models where the partial labels from a specific parsing abstraction are used as auxiliary tasks for the other one, and (iv) an mtl model that learns to produce both abstractions as main tasks.\nFor constituency parsing, we use the single-task model by BIBREF10 . The input is the raw sentence and the output for each token a single label of the form INLINEFORM0 = INLINEFORM1 . For dependency parsing we use the model by BIBREF11 to predict a single dependency label of the form INLINEFORM2 = INLINEFORM3 for each token.\nFor constituency parsing, instead of predicting a single label output of the form INLINEFORM0 , we generate three partial and separate labels INLINEFORM1 , INLINEFORM2 and INLINEFORM3 through three task-dependent feed-forward networks on the top of the stacked bilstms. This is similar to BIBREF28 . For dependency parsing, we propose in this work a mtl version too. We observed in preliminary experiments, as shown in Table TABREF14 , that casting the problem as 3-task learning led to worse results. Instead, we cast it as a 2-task learning problem, where the first task consists in predicting the head of a word INLINEFORM4 , i.e. predicting the tuple INLINEFORM5 , and the second task predicts the type of the relation INLINEFORM6 . The loss is here computed as INLINEFORM7 = INLINEFORM8 , where INLINEFORM9 is the partial loss coming from the subtask INLINEFORM10 .\nWe predict the partial labels from one of the parsing abstractions as main tasks. The partial labels from the other parsing paradigm are used as auxiliary tasks. The loss is computed as INLINEFORM0 = INLINEFORM1 , where INLINEFORM2 is an auxiliary loss and INLINEFORM3 its specific weighting factor.

        "evidence": "The majority of the English text available worldwide is generated by non-native speakers BIBREF0 . Such texts introduce a variety of challenges, most notably grammatical errors, and are of paramount importance for the scientific study of language acquisition as well as for NLP. Despite the ubiquity of non-native English, there is currently no publicly available syntactic treebank for English as a Second Language (ESL).\nTo address this shortcoming, we present the Treebank of Learner English (TLE), a first of its kind resource for non-native English, containing 5,124 sentences manually annotated with POS tags and dependency trees. The TLE sentences are drawn from the FCE dataset BIBREF1 , and authored by English learners from 10 different native language backgrounds. The treebank uses the Universal Dependencies (UD) formalism BIBREF2 , BIBREF3 , which provides a unified annotation framework across different languages and is geared towards multilingual NLP BIBREF4 . This characteristic allows our treebank to support computational analysis of ESL using not only English based but also multilingual approaches which seek to relate ESL phenomena to native language syntax.\nWhile the annotation inventory and guidelines are defined by the English UD formalism, we build on previous work in learner language analysis BIBREF5 , BIBREF6 to formulate an additional set of annotation conventions aiming at a uniform treatment of ungrammatical learner language. Our annotation scheme uses a two-layer analysis, whereby a distinct syntactic annotation is provided for the original and the corrected version of each sentence. This approach is enabled by a pre-existing error annotation of the FCE BIBREF7 which is used to generate an error corrected variant of the dataset. Our inter-annotator agreement results provide evidence for the ability of the annotation scheme to support consistent annotation of ungrammatical structures.\nFinally, a corpus that is annotated with both grammatical errors and syntactic dependencies paves the way for empirical investigation of the relation between grammaticality and syntax. Understanding this relation is vital for improving tagging and parsing performance on learner language BIBREF8 , syntax based grammatical error correction BIBREF9 , BIBREF10 , and many other fundamental challenges in NLP. In this work, we take the first step in this direction by benchmarking tagging and parsing accuracy on our dataset under different training regimes, and obtaining several estimates for the impact of grammatical errors on these tasks.\nTo summarize, this paper presents three contributions. First, we introduce the first large scale syntactic treebank for ESL, manually annotated with POS tags and universal dependencies. Second, we describe a linguistically motivated annotation scheme for ungrammatical learner English and provide empirical support for its consistency via inter-annotator agreement analysis. Third, we benchmark a state of the art parser on our dataset and estimate the influence of grammatical errors on the accuracy of automatic POS tagging and dependency parsing.\nThe remainder of this paper is structured as follows. We start by presenting an overview of the treebank in section SECREF2 . In sections SECREF3 and SECREF4 we provide background information on the annotation project, and review the main annotation stages leading to the current form of the dataset. The ESL annotation guidelines are summarized in section SECREF5 . Inter-annotator agreement analysis is presented in section SECREF6 , followed by parsing experiments in section SECREF7 . Finally, we review related work in section SECREF8 and present the conclusion in section SECREF9 .\nThird, we benchmark a state of the art parser on our dataset and estimate the influence of grammatical errors on the accuracy of automatic POS tagging and dependency parsing.",

These sentences were randomly selected by the creators of the dataset. This choice allows for a rough comparison between our results and theirs.\nThe second dataset (SCI) was a set of 220 sentences from the scientific literature. We sourced the sentences from the OA-STM corpus. This corpus is derived from the 10 most published in disciplines. It includes 11 articles each from the following domains: agriculture, astronomy, biology, chemistry, computer science, earth science, engineering, materials science, math, and medicine. The article text is made freely available and the corpus provides both an XML and a simple text version of each article.\nWe employed the following annotation process. Each OIE extractor was applied to both datasets with the settings described above. This resulted in the generation of triples for 199 of the 200 WIKI sentences and 206 of the 220 SCI sentences. That is there were some sentences in which no triples were extracted. We discuss later the sentences in which no triples were extracted. In total 2247 triples were extracted.\nIn total, 11262 judgements were obtained after running the annotation process. Every triple had at least 5 judgements from different annotators. All judgement data is made available. The proportion of overall agreement between annotators is 0.76 with a standard deviation of 0.25 on whether a triple is consequence of the given sentence. We also calculated inter-annotator agreement statistics. Using Krippendorff's alpha inter-annotator agreement was 0.44. This calculation was performed over all data and annotators as Krippendorff's alpha is designed to account for missing data and work across more than two annotators. Additionally, Fleiss' Kappa and Scott's pi were calculated pairwise between all annotators where there were overlapping ratings (i.e. raters had rated at least one triple in common). The average Fleiss's Kappa was 0.41 and the average of Scott's pi was 0.37. Using BIBREF14 as a guide, we interpret these statistics as suggesting there is moderate agreement between annotators and that agreement is above random chance.

        "answer": "ConceptNet and Atomic.",
        "evidence": "From the definitions of `explainable AI' and `context understanding,' in the previous section, we can derive the following corollary:\nThe explainability of AI algorithms is related to how context is processed, computationally, based on the machine's perceptual capabilities and on the external knowledge resources that are available.\nAlong this direction, the remainder of this chapter explores two concrete scenarios of context understanding, realized by neuro-symbolic architectures|i.e., hybrid AI frameworks that instruct machine perception (based on deep neural networks) with knowledge graphs. These examples were chosen to illustrate the general applicability of neuro-symbolism and its relevance to contemporary research problems.\nSpecifically, section SECREF3 considers context understanding for autonomous vehicles: we describe how a knowledge graph can be built from a dataset of urban driving situations and how this knowledge graph can be translated into a continuous vector-space representation. This embedding space can be used to estimate the semantic similarity of visual scenes by using neural networks as powerful, non-linear function approximators. Here, models may be trained to make danger assessments of the visual scene and, if necessary, transfer control to the human in complex scenarios. The ability to make this assessment is an important capability for autonomous vehicles, when we consider the negative ramifications for a machine to remain invariant to changing weather conditions, anomalous behavior of dynamic obstacles on the road (e.g., other vehicles, pedestrians), varied lighting conditions, and other challenging circumstances. We suggest neuro-symbolic fusion as one solution and, indeed, our results show that our embedding space preserves the semantic properties of the conceptual elements that make up visual scenes.\nIn section SECREF17, we describe context understanding for language tasks. Here, models are supplied with three separate modalities: external commonsense knowledge, unstructured textual context, and a series of answer candidates. In this task, models are tested on their ability to fuse together these disparate sources of information for making the appropriate logical inferences. We designed methods to extract adequate semantic structures (i.e., triples) from two comprehensive commonsense knowledge graphs, ConceptNet BIBREF6 and Atomic BIBREF7, and to inject this external context into language models. In general, open-domain linguistic context is useful for different tasks in Natural Language Processing (NLP), including: information-extraction, text-classification, extractive and abstractive summarization, and question-answering (QA). For ease of quantitative evaluation, we consider a QA task in section SECREF17. In particular, the task is to select the correct answer from a pool of candidates, given a question that specifically requires commonsense to resolve. For example, the question, If electrical equipment won't power on, what connection should be checked? is associated with `company', `airport', `telephone network', `wires', and `freeway'(where `wires' is the correct answer choice). We demonstrate that our proposed hybrid architecture out-performs the state-of-the-art neural approaches that do not utilize structured commonsense knowledge bases. Furthermore, we discuss how our approach maintains explainability in the model's decision-making process: the model has the joint task of learning an attention distribution over the commonsense knowledge context which, in turn, depends on the knowledge triples that were conceptually most salient for selecting the correct answer candidate, downstream. Fundamentally, the goal of this project is to make human interaction with chatbots and personal assistants more robust. For this to happen, it is crucial to equip intelligent agents with a shared understanding of general contexts, i.e., commonsense. Conventionally, machine commonsense had been computationally articulated using symbolic languages|Cyc being one of the most prominent outcomes of this approach BIBREF8. However, symbolic commonsense representations are neither scalable nor comprehensive, as they depend heavily on the knowledge engineering experts that encode them. In this regard, the advent of deep learning and, in particular, the possibility of fusing symbolic knowledge into sub-symbolic (neural) layers, has recently led to a revival of this AI research topic.\nWe designed methods to extract adequate semantic structures (i.e., triples) from two comprehensive commonsense knowledge graphs, ConceptNet [22] and Atomic [37], and to inject this external context into language models.

        "evidence": "Fallout is a series of post-apocalyptic role-playing video games—and later action role-playing games—created by Interplay Entertainment. The series is set during the 21st, 22nd and 23rd centuries, and its atompunk retrofuturistic setting and art work are influenced by the post-war culture of 1950s United States, with its combination of hope for the promises of technology and the lurking fear of nuclear annihilation. A forerunner of Fallout is Wasteland, a 1988 game developed by Interplay Productions to which the series is regarded as a spiritual successor.\n\nThe series' first title, Fallout, was developed by Black Isle Studios and released in 1997, and its sequel, Fallout 2, the following year. With the tactical role-playing game Fallout Tactics: Brotherhood of Steel, development was handed to Micro Forté and 14 Degrees East. In 2004, Interplay closed Black Isle Studios, and continued to produce Fallout: Brotherhood of Steel, an action game with role-playing elements for the PlayStation 2 and Xbox, without Black Isle Studios. Fallout 3, the third entry in the main series, was released in 2008 by Bethesda Softworks, and was followed by Fallout: New Vegas, developed by Obsidian Entertainment. Fallout 4 was released in 2015, and Fallout 76 released on November 14, 2018.\n\nBethesda Softworks owns the rights to the Fallout intellectual property. After acquiring it, Bethesda licensed the rights to make a massively multiplayer online role-playing game (MMORPG) version of Fallout to Interplay. The MMORPG got as far as beta stage under Interplay, but a lengthy legal dispute between Bethesda Softworks and Interplay halted the development of the game and led to its eventual cancellation, as Bethesda claimed in court that Interplay had not met the terms and conditions of the licensing contract. The case was settled in early 2012.\n\nOrigins\nThe ideas of the Fallout series began with Interplay Productions' Wasteland, released in 1988. At that time, Interplay was not a publisher and used Electronic Arts for distribution of the game. According to Interplay's founder, Brian Fargo, they wanted to explore a post-apocalyptic setting and created Wasteland for that. Sometime after release, Interplay decided to shift focus and become a publisher while still developing games. Fargo wanted to continue to use the Wasteland intellectual property but could not negotiate the rights back from Electronic Arts. Still wanting to do something in a post-apocalyptic setting, Fargo and his team decided to make a new setting and game. They determined what aspects of Wasteland were positives and wrote and developed a new game around them. The result was the first Fallout games, which released nearly ten years after Wasteland.",
        "answer": "Fallout (1997)\nReleased in October 1997, Fallout takes place in a post-apocalyptic Southern California, beginning in the year 2161. The protagonist, referred to as the Vault Dweller, is tasked with recovering a water chip in the Wasteland to replace the broken one in their underground shelter home, Vault 13. Afterwards, the Vault Dweller must thwart the plans of a group of mutants, led by a grotesque entity named the Master. Fallout was originally intended to run under the GURPS role-playing game system. However, a disagreement with the creator of GURPS, Steve Jackson, over the game's violent content required Black Isle Studios to develop the new SPECIAL system. Fallout's atmosphere and artwork are reminiscent of post-World War II United States during the Cold War era and the fear that the country was headed for nuclear war in the real world.",

        "evidence": "CLIR systems retrieve documents written in a language that is different from search query language BIBREF0 . The primary objective of CLIR is to translate or project a query into the language of the document repository BIBREF1 , which we refer to as Retrieval Corpus (RC). To this end, common CLIR approaches translate search queries using a Machine Translation (MT) model and then use a monolingual IR system to retrieve from RC. In this process, a translation model is treated as a black box BIBREF2 , and it is usually trained on a sentence level parallel corpus, which we refer to as Translation Corpus (TC).\nWe address a pitfall of using existing MT models for query translation BIBREF1 . An MT model trained on TC does not have any knowledge of RC. In an extreme setting, where there are no common terms between the target side of TC and RC, a well trained and tested translation model would fail because of vocabulary mismatch between the translated query and documents of RC. Assuming a relaxed scenario where some commonality exists between two corpora, a translation model might still perform poorly, favoring terms that are more likely in TC but rare in RC. Our hypothesis is that a search query translation model would perform better if a translated query term is likely to appear in the both retrieval and translation corpora, a property we call balanced translation.\nTo achieve balanced translations, it is desired to construct an MT model that is aware of RC vocabulary. Different types of MT approaches have been adopted for CLIR task, such as dictionary-based MT, rule-based MT, statistical MT etc. BIBREF3 . However, to the best of our knowledge, a neural search query translation approach has yet to be taken by the community. NMT models with attention based encoder-decoder techniques have achieved state-of-the-art performance for several language pairs BIBREF4 . We propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT). RAT is inspired from two word embedding learning approaches: Relevance-based Word Embedding (RWE) BIBREF5 and Continuous Bag of Words (CBOW) embedding BIBREF6 . We show that learning NMT with RAT enables it to generate balanced translation.\nNMT models learn to encode the meaning of a source sentence and decode the meaning to generate words in a target language BIBREF7 . In the proposed multi-task learning model, RAT shares the decoder embedding and final representation layer with NMT. Our architecture answers the following question: In the decoding stage, can we restrict an NMT model so that it does not only generate terms that are highly likely in TC?. We show that training a strong baseline NMT with RAT roughly achieves 16% improvement over the baseline. Using a qualitative analysis, we further show that RAT works as a regularizer and prohibits NMT to overfit to TC vocabulary.\nWe propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT).",

Therefore, we think that there is a room for improvements which can be achieved by interactively asking for additional information in conversational dialogs with users. This extra information can be used for improving policies of dialog systems. We call this approach the interactive learning from dialogs.\nWe can improve dialog systems in several aspects through interactive learning in a direct interaction with users. First, the most straightforward way obviously is getting the correct answer for questions that the system does not know. We can try to ask users for answers on questions that the system encountered in a conversation with a different user and did not understand it. Second, the system can ask the user for a broader explanation of a question. This explanation could help the system to understand the question and provide the correct answer. In addition, the system can learn correct policy for the question which allows providing answers without asking any extra information for similar questions next time. We hypothesize that users are willing to give such explanations because it could help them to find answers for their own questions. The last source of information that we consider for interactive learning is rephrasing, which could help when the system does know the concept but does not know the correct wording. This area is extensively studied for the purposes of information retrieval BIBREF5 , BIBREF6 .\nThe main purpose of the collected dataset is to enable interactive learning using the steps proposed above and potentially to evaluate how different systems perform on this task.\nCurrent approaches can only achieve around 50% accuracy on some question answering datasets.",

Similar distributed models of word or subword embeddings (or vector representations) find usage in sota, deep neural networks like BERT and its successors (BIBREF1, BIBREF2, BIBREF3). These deep networks generate contextual representations of words after been trained for extended periods on large corpora, unsupervised, using the attention mechanisms (BIBREF4).\nIt has been observed that various hyper-parameter combinations have been used in different research involving word2vec with the possibility of many of them being sub-optimal (BIBREF5, BIBREF6, BIBREF7). Therefore, the authors seek to address the research question: what is the optimal combination of word2vec hyper-parameters for intrinsic and extrinsic NLP purposes? There are astronomically high numbers of combinations of hyper-parameters possible for neural networks, even with just a few layers. Hence, the scope of our extensive work over three corpora is on dimension size, training epochs, window size and vocabulary size for the training algorithms (hierarchical softmax and negative sampling) of both skipgram and CBoW. The corpora used for word embeddings are English Wiki News Abstract by BIBREF8 of about 15MB, English Wiki Simple (SW) Articles by BIBREF9 of about 711MB and the Billion Word (BW) of 3.9GB by BIBREF10. The corpus used for sentiment analysis is the IMDb dataset of movie reviews by BIBREF11 while that for NER is Groningen Meaning Bank (GMB) by BIBREF12, containing 47,959 sentence samples. The IMDb dataset used has a total of 25,000 sentences with half being positive sentiments and the other half being negative sentiments. The GMB dataset has 17 labels, with 9 main labels and 2 context tags. It is however unbalanced due to the high percentage of tokens with the label 'O'. This skew in the GMB dataset is typical with NER datasets.\nThe objective of this work is to determine the optimal combinations of word2vec hyper-parameters for intrinsic evaluation (semantic and syntactic analogies) and extrinsic evaluation tasks (BIBREF13, BIBREF14), like SA and NER.

        "evidence": "Knowledge graphs have been proved to benefit many artificial intelligence applications, such as relation extraction, question answering and so on. A knowledge graph consists of multi-relational data, having entities as nodes and relations as edges. An instance of fact is represented as a triplet (Head Entity, Relation, Tail Entity), where the Relation indicates a relationship between these two entities. In the past decades, great progress has been made in building large scale knowledge graphs, such as WordNet BIBREF0 , Freebase BIBREF1 . However, most of them have been built either collaboratively or semi-automatically and as a result, they often suffer from incompleteness and sparseness.\nThe knowledge graph completion is to predict relations between entities based on existing triplets in a knowledge graph. Recently, a new powerful paradigm has been proposed to encode every element (entity or relation) of a knowledge graph into a low-dimensional vector space BIBREF2 , BIBREF3 . The representations of entities and relations are obtained by minimizing a global loss function involving all entities and relations. Therefore, we can do reasoning over knowledge graphs through algebraic computations.\nAlthough existing methods have good capability to learn knowledge graph embeddings, it remains challenging for entities with few or no facts BIBREF4 . To solve the issue of KB sparsity, many methods have been proposed to learn knowledge graph embeddings by utilizing related text information BIBREF5 , BIBREF6 , BIBREF7 . These methods learn joint embedding of entities, relations, and words (or phrases, sentences) into the same vector space. However, there are still three problems to be solved. (1) The combination methods of the structural and textual representations are not well studied in these methods, in which two kinds of representations are merely aligned on word level or separate loss function.

(3) Intuitively, entities with many facts depend more on well-trained structured representation while those with few or no facts might be largely determined by text descriptions. A good representation should learn the most valuable information by balancing both sides.\nIn this paper, we propose a new deep architecture to learn the knowledge representation by utilizing the existing text descriptions of entities. Specifically, we learn a joint representation of each entity from two information sources: one is structure information, and another is its text description. The joint representation is the combination of the structure and text representations with a gating mechanism. The gate decides how much information from the structure or text representation will carry over to the final joint representation. In addition, we also introduce an attention mechanism to select the most related information from text description under different contexts. Experimental results on link prediction and triplet classification show that our joint models can handle the sparsity problem well and outperform the baseline method on all metrics with a large margin.\nOur contributions in this paper are summarized as follows.\nAlthough existing methods have good capability to learn knowledge graph embeddings, it remains challenging for entities with few or no facts [Ji et al., 2016].

It is commonly used to train and evaluate neural network models that generate image descriptions (e.g. BIBREF2 ). An untested assumption behind the dataset is that the descriptions are based on the images, and nothing else. Here are the authors (about the Flickr8K dataset, a subset of Flickr30K):\n“By asking people to describe the people, objects, scenes and activities that are shown in a picture without giving them any further information about the context in which the picture was taken, we were able to obtain conceptual descriptions that focus only on the information that can be obtained from the image alone.” BIBREF1 \nWhat this assumption overlooks is the amount of interpretation or recontextualization carried out by the annotators. Let us take a concrete example. Figure FIGREF1 shows an image from the Flickr30K dataset.\nThis image comes with the five descriptions below. All but the first one contain information that cannot come from the image alone. Relevant parts are highlighted in bold:\nWe need to understand that the descriptions in the Flickr30K dataset are subjective descriptions of events. This can be a good thing: the descriptions tell us what are the salient parts of each image to the average human annotator. So the two humans in Figure FIGREF1 are relevant, but the two soap dispensers are not. But subjectivity can also result in stereotypical descriptions, in this case suggesting that the male is more likely to be the manager, and the female is more likely to be the subordinate. rashtchian2010collecting do note that some descriptions are speculative in nature, which they say hurts the accuracy and the consistency of the descriptions. But the problem is not with the lack of consistency here. Quite the contrary: the problem is that stereotypes may be pervasive enough for the data to be consistently biased. And so language models trained on this data may propagate harmful stereotypes, such as the idea that women are less suited for leadership positions.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices. I will build on earlier work on linguistic bias in general BIBREF3 , providing examples from the Flickr30K data, and present a taxonomy of unwarranted inferences. Finally, I will discuss several methods to analyze the data in order to detect biases.\nThe Flickr30K dataset (Young et al., 2014) is a collection of over 30,000 images with 5 crowdsourced descriptions each.

        "evidence": "Neural language models BIBREF0 , BIBREF1 , BIBREF2 have become an essential component in several areas of natural language processing (NLP), such as machine translation, speech recognition and image captioning. They have also become a common benchmarking application in machine learning research on recurrent neural networks (RNN), because producing an accurate probabilistic model of human language is a very challenging task which requires all levels of linguistic analysis, from pragmatics to phonology, to be taken into account.\nA typical language model is trained on text in a single language, and if one needs to model multiple languages the standard solution is to train a separate model for each language. This presupposes large quantities of monolingual data in each of the languages that needs to be covered and each model with its parameters is completely independent of any of the other models.\nWe propose instead to use a single model with real-valued vectors to indicate the language used, and to train this model with a large number of languages. We thus get a language model whose predictive distribution INLINEFORM0 is a continuous function of the language vector INLINEFORM1 , a property that is trivially extended to other neural NLP models. In this paper, we explore the “language space” containing these vectors, and in particular explore what happens when we move beyond the points representing the languages of the training corpus.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models. The second motivation is data sparseness, an issue that heavily influences the reliability of data-driven models. Resources are scarce for most languages in the world (and also for most domains in otherwise well-supported languages), which makes it hard to train reasonable parameters. By combining data from many languages, we hope to mitigate this issue.\nIn contrast to related work, we focus on massively multilingual data sets to cover for the first time a substantial amount of the linguistic diversity in the world in a project related to data-driven language modeling. We do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data. The only supervision that is giving during training is a language identifier as a one-hot encoding. From that and the actual training examples, the system learns dense vector representations for each language included in our data set along with the character-level RNN parameters of the language model itself.\nNeural language models (Bengio et al., 2003; Mikolov et al., 2010; Sundermeyer et al., 2012) have become an essential component in several areas of natural language processing (NLP), such as machine translation, speech recognition and image captioning.",

        "answer": "The Federal Reserve has a \"dual mandate\" to both keep prices stable and maintain the highest level of sustainable employment. Controlling inflation falls into the scope of price stability. The Fed has three main tools to achieve this goal. First, they can change the Federal Funds Rate which is the interest rate used by banks for inter-bank lending and is the foundation for interest rates more broadly. An increase in the Federal Funds Rate, will cause interest rates to increase for loans, mortgages, credit cards, etc. The higher costs of interest rates cause prices to decrease. Second, the Fed can set expectations for path of the Federal Funds Rate via announcements from Federal Open Market Committee (FOMC) and \"Fed Speak\" from individual Fed governors. These updates and commentary are based on the Feds marcoeconcomic forecasts and the individual opinions of the Fed governors. These expectations can influence the publics expectation for inflation and therefore the actual path of inflation. Lastly, the Fed has many technical tools for influencing credit markets and the interest rates on government bonds. These tools involve buying/selling US treasuries or providing assurances to select credit markets. These actions can tighten/loosen these credit markets and therfore indirectly influence actual interest rates.

        "evidence": "State-of-the-art (SOTA) artificial neural networks (ANNs) achieve impressive results in a variety of machine intelligence tasks. However, they largely rely on mechanisms that diverge from the original inspiration from biological neural networks. As a result, only a small part of this prolific field also contributes to computational neuroscience. In fact, this biological implausibility is also an important issue for machine intelligence. For their impressive performance, ANNs trade off other desired properties, which are present in biological systems. For example, ANN training often demands very large and labelled datasets. When labels are unavailable, self-supervised learning schemes exist, where supervisory error signals generated by the network itself are exploited and backpropagated from the output towards the input to update the network's parameters. However, this global propagation of signals in deep networks introduces another limitation. Namely, it prevents the implementation of efficient distributed computing hardware that would be based on only local signals from neighbouring physical nodes in the network, and is in contrast to local synaptic plasticity rules that partly govern biological learning. Several pieces of work have been addressing parts of the biological implausibility and hardware-inefficiency of backpropagation in ANNs. such as the need for exactly symmetric forward and backward weights or the waiting time caused by the network's forward-backward pass between two training updates in a layer (weight transport and update-locking problems). Recently, an approximation to backpropagation that is mostly Hebbian, i.e. relies on mostly pre-and post-synaptic activity of each synapse, has been achieved by reducing the global error requirements to 1-bit information. Two schemes that further localize the signal that is required for a weight update are Equilibrium Propagation and Predictive Coding. Both methods approximate backpropagation through Hebbian-like learning, by delegating the global aspect of the computation, from a global error signal, to a global convergence of the network state to an equilibrium. This equilibrium is reached through several iterative steps of feed-forward and feed-back communication throughout the network, before the ultimate weight update by one training example. The biological plausibility and hardware-efficiency of this added iterative process of signal propagation are open questions that begin to be addressed.\nMoreover, learning through backpropagation, and presumably also its approximations, has another indication of biological implausibility, which also significantly limits ANN applicability. Namely, it produces networks that are confused by small adversarial perturbations of the input, which are imperceptible by humans. It has recently been proposed that a defence strategy of \"deflection\" of adversarial attacks may be the ultimate solution to that problem. Through this strategy, to cause confusion in the network's inferred class, the adversary is forced to generate such a changed input that really belongs to the distribution of a different input class. Intuitively, but also strictly by definition, this deflection is achieved if a human assigns to the perturbed input the same label that the network does. Deflection of adversarial attacks in ANNs has been demonstrated by an elaborate scheme that is based on detecting the attacks. However, the human ability to deflect adversarial perturbations likely does not rely on detecting them, but rather on effectively ignoring them, making the deflecting type of robustness an emergent property of biological computation rather than a defence mechanism. The biological principles that underlie this property of robustness are unclear, but it might emerge from the distinct algorithms that govern learning in the brain.\nTherefore, what is missing is a biologically plausible model that can learn from fewer data-points, without labels, through local plasticity, and without feedback from distant layers. This model could then be tested for emergent adversarial robustness. A good candidate category of biological networks and learning algorithms is that of competitive learning. Neurons that compete for their activation through lateral inhibition are a common connectivity pattern in the superficial layers of the cerebral cortex). This pattern is described as winner-take-all (WTA), because competition suppresses activity of weakly activated neurons, and emphasizes strong ones. Combined with Hebbian-like plasticity rules, WTA connectivity gives rise to competitivelearning algorithms. These networks and learning schemes have been long studied (Von der and a large literature based on simulations and analyses describes their functional properties. A WTA neuronal layer, depending on its specifics, can restore missing input signals, perform decision making i.e. winner selection, and generate oscillations such as those that underlie brain rhythms. Perhaps more importantly, its neurons can learn to become selective to different input patterns, such as orientation of visual bars in models of the primary visual cortex (Von der, MNIST handwritten digits, CIFAR10 objects, spatiotemporal spiking patterns, and can adapt dynamically to model changing objects. The WTA model is indeed biologically plausible, Hebbian plasticity is local, and learning is input-driven, relying on only feed-forward communication of neurons -properties that seem to address several of the limitations of ANNs. However, the model's applicability is limited to simple tasks. That is partly because the related theoretical literature remains surprisingly unsettled, despite its long history, and the strong and productive community interest. described a very related theory but for a model that is largely incompatible with ANNs and thus less practical. It uses spiking and stochastic neurons, input has to be discretized, and each input feature must be encoded through multiple binary neurons. Moreover, it was only proven for neurons with an exponential activation function. It remains therefore unclear which specific plasticity rule and structure could optimize an ANN WTA for Bayesian inference. It is also unclear how to minimize a common loss function such as cross-entropy despite unsupervised learning, and how a WTA could represent varying families of probability distributions. In summary, on the theoretical side, an algorithm that is simultaneously normative, based on WTA networks and Hebbian unsupervised plasticity, performs Bayesian inference, and, importantly, is composed of conventional, i.e. non-spiking, ANN elements and is rigorously linked to modern ANN tools such as cross-entropy loss, would be an important advance but has been missing. On the practical side, evidence that Hebbian WTA networks could be useful for presently pertinent issues of modern ANNs such as adversarial robustness, generation of synthetic images, or faster learning, has remained limited. Here we aim to fill these gaps. Recently, when WTA networks were studied in a theoretical framework compatible with conventional machine learning (ML), but in the context of short-term as opposed to long-term Hebbian plasticity, it resulted in surprising practical advantages over supervised ANNs. A similar theoretical approach could also reveal unknown advantages of long-term Hebbian plasticity in WTA networks. In addition, it could provide insights into how a WTA microcircuit could participate in larger-scale computation by deeper cortical or artificial networks.\nHere we construct \"SoftHebb\", a biologically plausible WTA model that is based on standard ratebased neurons as in ANNs, can accommodate various activation functions, and learns without labels, using local plasticity and only feed-forward communication, i.e. the properties we seek in an ANN. Importantly, it is equipped with a simple normalization of the layer's activations, and an optional temperature-scaling mechanism, producing a soft WTA instead of selecting a single \"hard\" winner neuron. This allows us to prove formally that a SoftHebb layer is a generative mixture model that objectively minimizes its Kullback-Leibler (KL) divergence from the input distribution through Bayesian inference, thus providing a new formal ML-theoretic perspective of these networks. We complement our main results, which are theoretical, with experiments that are small-scale but produce intriguing results. As a generative model, SoftHebb has a broader scope than classification, but we test it on image classification tasks. Surprisingly, in addition to overcoming several inefficiencies of backpropagation, the unsupervised WTA model also outperforms a supervised two-layer perceptron in several aspects: learning speed and accuracy in the first presentation of the training dataset, robustness to noisy data and to one of the strongest white-box adversarial attacks, i.e. projected gradient descent (PGD), and without any explicit defence. Interestingly, the SoftHebb model also exhibits inherent properties of deflection of the adversarial attacks, and generates object interpolations.\nState-of-the-art (SOTA) artificial neural networks (ANNs) achieve impressive results in a variety of machine intelligence tasks. However, they largely rely on mechanisms that diverge from the original inspiration from biological neural networks. As a result, only a small part of this prolific field also contributes to computational neuroscience. In fact, this biological implausibility is also an important issue for machine intelligence. For their impressive performance, ANNs trade off other desired properties, which are present in biological systems. For example, ANN training often demands very large and labelled datasets. When labels are unavailable, self-supervised learning schemes exist, where supervisory error signals generated by the network itself are exploited and backpropagated from the output towards the input to update the network's parameters. However, this global propagation of signals in deep networks introduces another limitation. Namely, it prevents the implementation of efficient distributed computing hardware that would be based on only local signals from neighbouring physical nodes in the network, and is in contrast to local synaptic plasticity rules that partly govern biological learning. Several pieces of work have been addressing parts of the biological implausibility and hardware-inefficiency of backpropagation in ANNs. such as the need for exactly symmetric forward and backward weights or the waiting time caused by the network's forward-backward pass between two training updates in a layer (weight transport and update-locking problems). Recently, an approximation to backpropagation that is mostly Hebbian, i.e. relies on mostly pre-and post-synaptic activity of each synapse, has been achieved by reducing the global error requirements to 1-bit information. Two schemes that further localize the signal that is required for a weight update are Equilibrium Propagation and Predictive Coding. Both methods approximate backpropagation through Hebbian-like learning, by delegating the global aspect of the computation, from a global error signal, to a global convergence of the network state to an equilibrium.

On one hand, it is still structured, as it incorporates information about slots in KB schema; on the other hand, it is flexible, as it does not use information about the values contained in the KB records. This makes it easily adaptable to new values. These desirable properties are achieved by a separate decoder for each informable slot and a multi-label classifier for the requestable slots. Those components explicitly assign values to slots like the fully structured approach, while also preserving the capability of dealing with out-of-vocabulary words like the free-form approach. By using these two types of decoders, FSDM produces only valid belief states, overcoming the limitations of the free-form approach. Further, FSDM has a new module called response slot binary classifier that adds extra supervision to generate the slots that will be present in the response more precisely before generating the final textual agent response (see Section \"Methodology\" for details).\nFurther, FSDM has a new module called response slot binary classifier that adds extra supervision to generate the slots that will be present in the response more precisely before generating the final textual agent response (see Section \"Methodology\" for details).",

        "question": "In XPersona, the training sets are translated automatically or manually?",
        "answer": "Automatically.",
        "evidence": "Personalized dialogue agents have been shown efficient in conducting human-like conversation. This progress has been catalyzed thanks to existing conversational dataset such as Persona-chat BIBREF0, BIBREF1. However, the training data are provided in a single language (e.g., English), and thus the resulting systems can perform conversations only in the training language. For wide, commercial dialogue systems are required to handle a large number of languages since the smart home devices market is increasingly international BIBREF2. Therefore, creating multilingual conversational benchmarks is essential, yet challenging since it is costly to perform human annotation of data in all languages.\nA possible solution is to use translation systems before and after the model inference, a two-step translation from any language to English and from English to any language. This comes with three major problems: 1) amplification of translation errors since the current dialogue systems are far from perfect, especially with noisy input; 2) the three-stage pipeline system is significantly slower in terms of inference speed; and 3) high translation costs since the current state-of-the-art models, especially in low resources languages, are only available using costly APIs.\nIn this paper, we analyze two possible workarounds to alleviate the aforementioned challenges. The first is to build a cross-lingual transferable system by aligning cross-lingual representations, as in BIBREF3, in which the system is trained on one language and zero-shot to another language. The second is to learn a multilingual system directly from noisy multilingual data (e.g., translated data), thus getting rid of the translation system dependence at inference time.\nTo evaluate the aforementioned systems, we propose a dataset called Multilingual Persona-Chat, or XPersona, by extending the Persona-Chat corpora BIBREF1 to six languages: Chinese, French, Indonesian, Italian, Korean, and Japanese. In XPersona, the training sets are automatically translated using translation APIs with several human-in-the-loop passes of mistake correction. In contrast, the validation and test sets are annotated by human experts to facilitate both automatic and human evaluations in multiple languages.\nFurthermore, we propose competitive baselines in two training settings, namely, cross-lingual and multilingual, and compare them with translation pipeline models. Our baselines leverage pre-trained cross-lingual BIBREF4 and multilingual BIBREF5 models.\nAn extensive automatic and human evaluation BIBREF6 of our models shows that a multilingual system is able to outperform strong translation-based models and on par with or even improve the monolingual model. The cross-lingual performance is still lower than other models, which indicates that cross-lingual conversation modeling is very challenging. The main contribution of this paper are summarized as follows:\nWe present the first multilingual non-goal-oriented dialogue benchmark for evaluating multilingual generative chatbots.\nWe provide both cross-lingual and multilingual baselines and discuss their limitations to inspire future research.\nWe show the potential of multilingual systems to understand the mixed language dialogue context and generate coherent responses.\nIn XPersona, the training sets are automatically translated using translation APIs with several human-in-the-loop passes of mistake correction.",

These types of differences are far subtler than abusive language, but they can provide valuable insight into the roots of more extreme acts of discrimination. Subtle differences are difficult to observe because each case on its own could be attributed to circumstance, a passing comment or an accidental word.

        "evidence": "Both neural and statistical machine translation approaches are highly reliant on the availability of large amounts of data and are known to perform poorly in low resource settings. Recent crowd-sourcing efforts and workshops on machine translation have resulted in small amounts of parallel texts for building viable machine translation systems for low-resource pairs BIBREF0 . But, they have been shown to suffer from low accuracy (incorrect translation) and low coverage (high out-of-vocabulary rates), due to insufficient training data. In this project, we try to address the high OOV rates in low-resource machine translation systems by leveraging the increasing amount of multilingual content available on the Internet for enriching the bilingual lexicon.\nComparable corpora such as Wikipedia, are collections of topic-aligned but non-sentence-aligned multilingual documents which are rich resources for extracting parallel sentences from. For example, Figure FIGREF1 shows that there are equivalent sentences on the page about Donald Trump in Tamil and English, and the phrase alignment for an example sentence is shown in Table TABREF4 .\nTable TABREF2 shows that there are at least tens of thousands of bilingual articles on Wikipedia which could potentially have at least as many parallel sentences that could be mined to address the scarcity of parallel sentences as indicated in column 2 which shows the number of sentence-pairs in the largest available bilingual corpora for xx-en. As shown by BIBREF1 ( BIBREF1 ), the illustrated data sparsity can be addressed by extending the scarce parallel sentence-pairs with those automatically extracted from Wikipedia and thereby improving the performance of statistical machine translation systems.\nIn this paper, we will propose a neural approach to parallel sentence extraction and compare the BLEU scores of machine translation systems with and without the use of the extracted sentence pairs to justify the effectiveness of this method. Compared to previous approaches which require specialized meta-data from document structure or significant amount of hand-engineered features, the neural model for extracting parallel sentences is learned end-to-end using only a small bootstrap set of parallel sentence pairs.\nIn this paper, we will propose a neural approach to parallel sentence extraction and compare the BLEU scores of machine translation systems with and without the use of the extracted sentence pairs to justify the effectiveness of this method.",

        "evidence": "",
        "answer": "The journey from cold prospect to loyal customer is as tricky as the alchemy that transforms a stranger into a close personal friend. While there are a thousand possible paths, a handful of methods have proven consistently effective as triggers for moving prospects down the funnel toward purchase.\n\nThe first is personal referral. A personal referral or endorsement is worth more than 10,000 words of marketing material. Knowing that someone we know and trust can vouch for a product or service counts for so much that we will instinctually lower our guard and open our ears to a sales pitch.\n\nSecond is the testimonial. Like a referral, knowing that someone else -- generally a brand we know or at least can recognize -- uses a product or service predisposes us to try it ourselves. This is especially true of unknown brands or products. Think of when you pass a new restaurant. You may not know the name, the menu or the quality but if there's a crowd inside we naturally assume it must be good. The same goes for a new brand -- when you see others are endorsing it, we relax our natural suspicion and are more willing to give it a try.\n\nThird is the offer. It's not enough to build a great product. You have to overcome people's natural reluctance to open their wallets when you're asking them to pay full price. The offer can take many forms -- from a discount to a free trial to a bonus offer. Adding urgency -- such as a limited quantity or expiration on the offer can also help.\n\nFourth is the three-step. This works especially well for big-ticket items or purchases that involve a large number of people or disruption to an organization. The 3-step acknowledges that nobody buys a $2,000,000 solution without giving it a lot of thought. So first we simply get them to raise their hand and express interest. This can be done through a top-of-funnel asset like an eBook or webinar. The second step is an offer that gets them more involved with the product, such as a demo. And the third step is a face-to-face meeting with the sales team.\n\nFifth is third-party validation. Many prospects have an allergic reaction to anything that smells like marketing. But what if they are reading a glowing piece about your. in the Wall Street Journal? Or Gartner places you at the top of one of its magic quadrants? This kind of validation from what is perceived as an objective source carries a lot more weight than marketing content. \n\nIn practice, most businesses use a combination of the five techniques described above. Each will resonate in different ways with prospects; and in combination they can be extremely effective at creating that aura around your company and products that cause the prospect to push the \"Buy now\" button.",

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nRecently, the Pew Research Center (Center, 2017) reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”",

This is in stark contrast to existing works. devised the model f Θ to fit to a single scene, and the spatial gradient ∇ x,y,z fΘ (x, y, z) can be conveniently computed because it does not involve the sampling procedure.; used a non-spatial global feature for inference and hence bypassed sampling. In our learning framework, the spatial gradient computation must undergo the sampling procedure.\nWe name our gradient computation involving the sampling operation as the Pixel Conditioned Gradients and derive a closed-form solution, Differentiable Gradient Sampling (DGS), for handling forward and backward propagation. Figure(a) provides an illustration of our training pipeline. Each layer in our network tracks both the response of the layer as well as its spatial gradient w.r.t. (x, y, z). While it is well established to track the layer-wise spatial gradient for fully-connected (FC) layers or convolutions in existing works, tracking the spatial gradients and back-propagating the loss to the feature map pixels ϕ through the sampling module has not been studied. To this end, we derive the closed-form sampling scheme for tracking and propagating the spatial gradients ∂ϕ ∂x,y,z through the sampling layer. Background -2D Differentiable Sampling. Differentiably sampling pixel values from a grid of 2D feature map with the given pixel locations (i, j) is a common operation. Throughout our paper, we define the pixel coordinates in the Normalized Device Coordinate (NDC) system that ranges from -1 to 1. As illustrated in Fig., given the feature map ϕ and the sampling locations (i, j), the resulting sampled value ϕ(i, j) is\nPlease refer to Fig.(c) for the definitions of α, β and ϕ A , ϕ B , ϕ C , ϕ D . Without loss of generality we use bilinear interpolation. During training, the gradient from the loss can be back-propagated via\n2D Differentiable Gradient Sampling. Our learning framework (Sec. 3.1, Fig.(a)) requires the extension of the sampling capability from just the feature value response ϕ i,j to its spatial gradient ∇ i,j ϕ(i, j). During the forward and the backward propagation, both the sampled feature response ϕ i,j and its spatial gradient ∇ i,j ϕ(i, j) are recorded for further propagation (Fig.(e)):\nHence, during the forward pass, we compute the spatial gradient via Eq. 5 in addition to the existing value sampling (Eq. 3). During the backward pass, we compute the loss gradient over the spatial gradient via\nwhere w and h are the width and height of a pixel in NDC, s.t. w = 2/W and h = 2/H for the feature map with the size W × H.\n3D Differentiable Gradient Sampling. We now extend the sampling to 3D. We model the camera as the pin-hole camera. For any point (x, y, z) in the camera space, we seek for its projected 2D locations (i, j) based on the focal length\nDuring the backward propagation procedure, the DGS accumulates the gradient via Comparison with state-of-the-art approaches. We choose to compare to recent representative state-of-the-art approaches, including OccNet, DISN, CoReNet and D 2 IM-Net. Quantitative results are reported in Tab. 3 for the low-realism evaluation setting, and in Tab. 1 for the high-realism setting, where our results outperform all the state-of-the-art results in all the settings. Please refer to Sec. A for qualitative comparison, implementation details and the evaluation metrics.\nFor our low-realism evaluation setting, all the baseline approaches reported their results in the papers. For OccNet and DISN, the reported results are based on knowing the category canonical view prior, which demonstrates considerable privilege with respect to accuracy. Hence, we mark the results from the literature as OccNet-Privilege and DISN-Privilege (OccNet-Priv. and DISN-Priv. for short). Compared to their privileged setting, our results demonstrate superior results even without the category canonical view prior privilege. To further provide the the baseline results where these two approaches are without the category canonical view prior, we retrain their models with the released codes, and report the results in the \"OccNet\" and \"DISN\" row respectively. The results further provide evidence that the category canonical view prior demonstrates privilege on accuracy, as observed in.\nFor our high-realism evaluating setting, since the results for Occnet and DISN are not directly available from the paper, we retrain their model from the released codes (without the category canonical view prior) on the high-realism data provided by. We also retrain CoReNet using their released codes and obtain results better than reported in their original paper (61.5 as mIoU instead of 59.5). Our model still consistently outperforms all the baselines on almost all the categories. We emphasize that our comparison to CoReNet is a direct ablation comparison where we directly follow their experimental setup and model size. Furthermore, our approach only utilizes the closeto-surface occupancy labels, which is a subset of the whole occupancy labels for all the query point.\nOur model still outperforms the baseline and provides convincing evidence that our supervision loss function demonstrate better results than the original CoReNet approach. We attribute the superiority of our approach to our particular focus toward the difficult close-to-surface region similar to hard negative mining. Ablation Study. We further conduct ablation studies to further validate the importance of derived DGS module, via attempting work-around training methods without DGS. i) NoGrad -To test the performance of the baseline when only the surface data are provided, we train this ablation model in exactly the same way compared to its original model, with the only exceptions that only the near-surface points are equipped with training labels, and we mask out all the training labels from the non-surface query points (where it is not necessary to backpropagate the loss gradient of the spatial gradient using DGS). To further evaluate how the rate of known voxels affects the learning performance, we enlarge the near-surface region and evaluate when the rate is 10%, 30% and 50%. An increase in the performances among these baselines would indicate the importance of knowing more voxel labels if our proposed gradient loss (Eq. 1) is not imposed.\nii) FixedE -We train with both the near-surface as well as the spatial gradient supervision, without DGS -meaning the loss gradient of the spatial gradient would not back-propagate to any module before the sampling module -in our case, the feature encoder network. Note all the other losses without gradient sampling can still back-propagated to the feature maps. We report the ablation results in Tab. 1. Both experiments are conducted with the high-realism ShapeNet data. Once again, we comfortably outperform all the baselines, validating the essential roles of DGS in our learning framework.\nFigure: Qualitative comparisons on one challenging test case on ScannetV2.

The larger the blue region is, the higher F1 score would be. 4.2 LEARNING FROM REAL SCANNED DATASETS (SCANNETV2) Dataset. We use ScannetV2  for training and evaluating the performance of the models on the real images. We follow the standard training / testing split as used in and, where 1513 scenes are for trainval (with 1201 for training and 312 for validation), and 100 for testing. Each scene is provided with multiple image capture as well as the associated camera pose. We train the models with all the views given in the training / validation set (2423872 frames in total, after filtering out frames with invalid extrinsic poses), while for testing, we select 10 frames with different extrinsic poses for each test scene. Practically, since all the frames of the scenes are in the form of video clips, with adjacent frames associated with similar extrinsic cameras poses, we select the 10 frames for each frame via extracting every 100 frames from each scene video (e.g. Frame 1, 101, 201, ..., 901), resulting in 1000 frames in total in our test set (10 frames per scene, with 100 test scenes).\nMetrics. We use the same evaluation metrics following and.\nSince we are the first, to our knowledge, to evaluate single view 3D implicit reconstruction on the ScannetV2 benchmark, and here we only evaluate the geometries within the camera view frustum rather than the whole scene geometries as in;. In addition, we also only evaluate the geometries in front of the amodal depth for each pixel ray. We define the amodal depth for a pixel ray to be delineated by the minimum between the closest structure-category surface (e.g. walls and doors, etc) and the farthest surface. In practice, in order to accommodate the evaluation of the surfaces right on the amodal depth, we slack the evaluation scope with a factor λ (1.05 in our case) multiplied with the amodal depth. This evaluation protocol would be equivalent to the \"single-layered\" protocol used in, within our single-view scenario. Due to the inherent ambiguity of the scaling and shifting of the predicted 3D single view geometry, we follow them by regressing the best scale and shift comparing the predicted depth with the ground truth depth. For approaches that predict 3D surfaces, the rendered depth map from the predicted mesh would be used for calculating the scale and shift.\nBaselines. Since we demonstrate the first attempt to conduct the implicit reconstruction of singleview scenes, very few exiting works provide a direct baseline performance to our task. For Occ-Net, since its image feature extraction is not local, and its gradient propa- Figure: Two representative failure cases of our approach. gation does not require sampling, we use its direct application with Gropp et al. () \"OccNet + GeoReg\" as one baseline. We train DISN with the TSDF voxelization labels. For CoReNet, we stick to its own voxelization and internal filling toolbox for obtaining the training labels. Since CoReNet can only predict geometries within the fixed range of space, we tried our best to pick the best cube location based on the dataset statistics. We also incorporate depth approaches for comparison by finetuning their weights on ScannetV2. Lastly, we compare with the two ablation models NoGrad and FixedE as introduced in Sec. 4.1.\nResults. We provide quantitative comparison in Tab. 2 and qualitative comparison in Fig. respectively. Our model outperforms all state-of-the-art approaches as well as the ablation models. Compared to the synthetic data scenario in Tab. 3 and 1, our model demonstrates even larger advantages when compared to existing state-of-the-art approaches, as our motivation stems from addressing learning from imperfect 3D labels directly from the real scan data. Compared to single-view depth prediction approaches trained on massive data, our approach does not prevail on \"Acc\" and \"Prec\". This is due to the fact that these two metrics only project the predicted surface to the ground truth surface, giving advantages to approaches that only predict the visible surface. Our approach still prevails for other metrics (Chamfer Distance and F1), which are considered as the most important metrics. Generalization to Unseen Scenes (Pix3d and Open-Domain Images). We further test our model without further finetuning directly on unseen scenes for evaluating the generalizability of the learned model. We tried our model on Pix3d as well as test images downloaded directly from the internet. We provide a detailed qualitative comparison in Fig. and more results in Fig.. The results further indicate our learning framework exhibits promise for unseen scene generalization. Failure Cases. We provide two representative failure cases of our approach in Fig.. The first case (the first row) demonstrates difficulties in predicting the floor occupancy as a result of the noisy and non-watertight mesh during training. The second case (the second row) shows that our model cannot identify objects (e.g. chairs) and well predicts the invisible part of them.\nA distinct difference compared to existing works is that our spatial gradient ∇ x,y,z fΘ (ϕ; x, y, z) is also conditioned on the pixels in ϕ. This is in stark contrast to existing works. devised the model f Θ to fit to a single scene, and the spatial gradient ∇ x,y,z fΘ (x, y, z) can be conveniently computed because it does not involve the sampling procedure.; used a non-spatial global feature for inference and hence bypassed sampling. In our learning framework, the spatial gradient computation must undergo the sampling procedure.\nWe name our gradient computation involving the sampling operation as the Pixel Conditioned Gradients and derive a closed-form solution, Differentiable Gradient Sampling (DGS), for handling forward and backward propagation. Figure(a) provides an illustration of our training pipeline. Each layer in our network tracks both the response of the layer as well as its spatial gradient w.r.t. (x, y, z). While it is well established to track the layer-wise spatial gradient for fully-connected (FC) layers or convolutions in existing works, tracking the spatial gradients and back-propagating the loss to the feature map pixels ϕ through the sampling module has not been studied. To this end, we derive the closed-form sampling scheme for tracking and propagating the spatial gradients ∂ϕ ∂x,y,z through the sampling layer. Background -2D Differentiable Sampling. Differentiably sampling pixel values from a grid of 2D feature map with the given pixel locations (i, j) is a common operation. Throughout our paper, we define the pixel coordinates in the Normalized Device Coordinate (NDC) system that ranges from -1 to 1. As illustrated in Fig., given the feature map ϕ and the sampling locations (i, j), the resulting sampled value ϕ(i, j) is\nPlease refer to Fig.(c) for the definitions of α, β and ϕ A , ϕ B , ϕ C , ϕ D . Without loss of generality we use bilinear interpolation. During training, the gradient from the loss can be back-propagated via\n2D Differentiable Gradient Sampling. Our learning framework (Sec. 3.1, Fig.(a)) requires the extension of the sampling capability from just the feature value response ϕ i,j to its spatial gradient ∇ i,j ϕ(i, j). During the forward and the backward propagation, both the sampled feature response ϕ i,j and its spatial gradient ∇ i,j ϕ(i, j) are recorded for further propagation (Fig.(e)):\nHence, during the forward pass, we compute the spatial gradient via Eq. 5 in addition to the existing value sampling (Eq. 3). During the backward pass, we compute the loss gradient over the spatial gradient via\nwhere w and h are the width and height of a pixel in NDC, s.t. w = 2/W and h = 2/H for the feature map with the size W × H.\n3D Differentiable Gradient Sampling. We now extend the sampling to 3D. We model the camera as the pin-hole camera. For any point (x, y, z) in the camera space, we seek for its projected 2D locations (i, j) based on the focal length\nDuring the backward propagation procedure, the DGS accumulates the gradient via Comparison with state-of-the-art approaches. We choose to compare to recent representative state-of-the-art approaches, including OccNet, DISN, CoReNet and D 2 IM-Net. Quantitative results are reported in Tab. 3 for the low-realism evaluation setting, and in Tab. 1 for the high-realism setting, where our results outperform all the state-of-the-art results in all the settings. Please refer to Sec. A for qualitative comparison, implementation details and the evaluation metrics.\nFor our low-realism evaluation setting, all the baseline approaches reported their results in the papers. For OccNet and DISN, the reported results are based on knowing the category canonical view prior, which demonstrates considerable privilege with respect to accuracy. Hence, we mark the results from the literature as OccNet-Privilege and DISN-Privilege (OccNet-Priv. and DISN-Priv. for short). Compared to their privileged setting, our results demonstrate superior results even without the category canonical view prior privilege. To further provide the the baseline results where these two approaches are without the category canonical view prior, we retrain their models with the released codes, and report the results in the \"OccNet\" and \"DISN\" row respectively. The results further provide evidence that the category canonical view prior demonstrates privilege on accuracy, as observed in.\nFor our high-realism evaluating setting, since the results for Occnet and DISN are not directly available from the paper, we retrain their model from the released codes (without the category canonical view prior) on the high-realism data provided by. We also retrain CoReNet using their released codes and obtain results better than reported in their original paper (61.5 as mIoU instead of 59.5). Our model still consistently outperforms all the baselines on almost all the categories. We emphasize that our comparison to CoReNet is a direct ablation comparison where we directly follow their experimental setup and model size. Furthermore, our approach only utilizes the closeto-surface occupancy labels, which is a subset of the whole occupancy labels for all the query point.\nOur model still outperforms the baseline and provides convincing evidence that our supervision loss function demonstrate better results than the original CoReNet approach.

So much so that it is easy to overlook their potential to benefit society by promoting equity, diversity, and fairness. For example, machines do not take bribes to do their jobs, they can determine eligibility for a loan without being influenced by the color of the applicant's skin, and they can provide access to information and services without discrimination based on gender or sexual orientation. Nonetheless, as machine learning systems become more human-like in their predictions, they can also perpetuate human biases. Some learned biases may be beneficial for the downstream application (e.g., learning that humans often use some insect names, such as spider or cockroach, to refer to unpleasant situations). Other biases can be inappropriate and result in negative experiences for some groups of people. Examples include, loan eligibility and crime recidivism prediction systems that negatively assess people belonging to a certain pin/zip code (which may disproportionately impact people of a certain race) BIBREF0 and resumé sorting systems that believe that men are more qualified to be programmers than women BIBREF1 . Similarly, sentiment and emotion analysis systems can also perpetuate and accentuate inappropriate human biases, e.g., systems that consider utterances from one race or gender to be less positive simply because of their race or gender, or customer support systems that prioritize a call from an angry male over a call from the equally angry female.\nPredictions of machine learning systems have also been shown to be of higher quality when dealing with information from some groups of people as opposed to other groups of people. For example, in the area of computer vision, gender classification systems perform particularly poorly for darker skinned females BIBREF2 . Natural language processing (NLP) systems have been shown to be poor in understanding text produced by people belonging to certain races BIBREF3 , BIBREF4 . For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.\nEven though there is some recent work highlighting such inappropriate biases (such as the work mentioned above), each such past work has largely focused on just one or two systems and resources. Further, there is no benchmark dataset for examining inappropriate biases in natural language systems. In this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC). We used the EEC as a supplementary test set in a recent shared task on predicting sentiment and emotion intensity in tweets, SemEval-2018 Task 1: Affect in Tweets BIBREF5 . In particular, we wanted to test a hypothesis that a system should equally rate the intensity of the emotion expressed by two sentences that differ only in the gender/race of a person mentioned. Note that here the term system refers to the combination of a machine learning architecture trained on a labeled dataset, and possibly using additional language resources. The bias can originate from any or several of these parts. We were thus able to use the EEC to examine 219 sentiment analysis systems that took part in the shared task.\nWe compare emotion and sentiment intensity scores that the systems predict on pairs of sentences in the EEC that differ only in one word corresponding to race or gender (e.g., `This man made me feel angry' vs. `This woman made me feel angry'). We find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender. We also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.\nDespite the work we describe here and what others have proposed in the past, it should be noted that there are no simple solutions for dealing with inappropriate human biases that percolate into machine learning systems. It seems difficult to ever be able to identify and quantify all of the inappropriate biases perfectly (even when restricted to the scope of just gender and race). Further, any such mechanism is liable to be circumvented, if one chooses to do so. Nonetheless, as developers of sentiment analysis systems, and NLP systems more broadly, we cannot absolve ourselves of the ethical implications of the systems we build. Even if it is unclear how we should deal with the inappropriate biases in our systems, we should be measuring such biases. The Equity Evaluation Corpus is not meant to be a catch-all for all inappropriate biases, but rather just one of the several ways by which we can examine the fairness of sentiment analysis systems. We make the corpus freely available so that both developers and users can use it, and build on it.\nAutomatic systems have had a significant and beneficial impact on all walks of human life.

These laws can be paraphrased as follows:\n\nA body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.\nWhen a body is acted upon by a force, the time rate of change of its momentum equals the force.\nIf two bodies exert forces on each other, these forces have the same magnitude but opposite directions.\nThe three laws of motion were first stated by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), originally published in 1687. Newton used them to investigate and explain the motion of many physical objects and systems, which laid the foundation for classical mechanics. In the time since Newton, the conceptual content of classical physics has been reformulated in alternative ways, involving different mathematical approaches that have yielded insights which were obscured in the original, Newtonian formulation. Limitations to Newton's laws have also been discovered; new theories are necessary when objects move at very high speeds (special relativity), are very massive (general relativity), or are very small (quantum mechanics).",

        "evidence": "Humor recognition refers to the task of deciding whether a sentence/spoken-utterance expresses a certain degree of humor. In most of the previous studies BIBREF1 , BIBREF2 , BIBREF3 , humor recognition was modeled as a binary classification task. In the seminal work BIBREF1 , a corpus of INLINEFORM0 “one-liners\" was created using daily joke websites to collect humorous instances while using formal writing resources (e.g., news titles) to obtain non-humorous instances. Three humor-specific stylistic features, including alliteration, antonymy, and adult slang were utilized together with content-based features to build classifiers. In a recent work BIBREF3 , a new corpus was constructed from the Pun of the Day website. BIBREF3 explained and computed latent semantic structure features based on the following four aspects: (a) Incongruity, (b) Ambiguity, (c) Interpersonal Effect, and (d) Phonetic Style. In addition, Word2Vec BIBREF4 distributed representations were utilized in the model building.\nBeyond lexical cues from text inputs, other research has also utilized speakers' acoustic cues BIBREF2 , BIBREF5 . These studies have typically used audio tracks from TV shows and their corresponding captions in order to categorize characters' speaking turns as humorous or non-humorous. Utterances prior to canned laughter that was manually inserted into the shows were treated as humorous, while other utterances were treated as negative cases.\nConvolutional Neural Networks (CNNs) have recently been successfully used in several text categorization tasks (e.g., review rating, sentiment recognition, and question type recognition). Kim2014,Johnson2015,Zhang2015 suggested that using a simple CNN setup, which entails one layer of convolution on top of word embedding vectors, achieves excellent results on multiple tasks. Deep learning recently has been applied to computational humor research BIBREF5 , BIBREF6 . In Bertero2016LREC, CNN was found to be the best model that uses both acoustic and lexical cues for humor recognition. By using Long Short Time Memory (LSTM) cells BIBREF7 , Bertero2016NAACL showed that Recurrent Neural Networks (RNNs) perform better on modeling sequential information than Conditional Random Fields (CRFs) BIBREF8 .\nFrom the brief review, it is clear that corpora used in humor research so far are limited to one-line puns or jokes and conversations from TV comedy shows. There is a great need for an open corpus that can support investigating humor in presentations.

They use GIS to store, analyse, and quantify data with geographical information to show how it relates to other components.\n\nGIS compliments every industry. And forward-thinking companies recognise that with the ability to analyse information efficiently, they can optimise their efforts, use resources more efficiently, and have an advantage in their industry.\n\nThere are many advantages that a business gains when using GIS, and it is transforming industries such as utilities, infrastructure, environment management, and others:\n\nThe industries using GIS serve some of our most fundamental needs.\nEnvironmental Agencies\n\nGIS gathers and stores critical data for environmental agencies to track and monitor habitat, wetland, and coastal shoreline erosion, identify locations where threatened species live, water sources and other natural resources. It can also help to track patterns and help predict natural disasters, glacier changes and soil erosion.\n\nAll of the environmental data gathered is essential in helping with conservation, protection and restoration efforts. Other industries can also access and utilise the data collected by researchers and conservationists.\nUtility Companies\n\nOne of the most active users of GIS is the utility sector, and they use it to help with: \n\n    Managing grids and identifying patterns in customer usage, outages and supply issues\n    Tracking and monitoring pipelines\n    Locating water pipes and cables\n    Wireless networks\n    Construction planning\n    Monitor assets and field workers\n\nGIS, with its comprehensive database, helps to maintain and monitor overhead and underground utilities, improving efficiency and effectiveness and saving time and money\nInfrastructure Companies\n\nThe planning and development of our roads, electricity, water supply lines, buildings, and society’s basic framework is mapped, managed, and monitored by companies that incorporate GIS in the infrastructure industry.\n\nGIS simplifies communications, improves efficiency and effectiveness for field workers, helps to monitor assets and workers, tracks and stores customer usage and issues, improves customer/client satisfaction, and much more.\nTelecommunications\n\nGIS is widely used in the telecom sector to help monitor real-time data about current use, outages, and signal strength to help them better understand customers’ patterns and needs. \n\nThe telecom companies also use GIS to help optimise their resources effectively and efficiently, mitigate problems and plan for future growth.\nRetail\n\nRetail stores depend on knowing where their customer base lives or works and how far they are willing to travel to buy goods. GIS supplies essential data to help retail companies determine location, optimise inventory and sales, and plan their marketing campaigns to reach their ideal clientele.\nGovernment\n\nGeographical information is critical for the government to make decisions based on real-time data.  Government operations are spatial, whether for emergency response and management, fires, accidents, utilities, infrastructure, etc.\nAgriculture\n\nFood is a basic need for humans and animals. The agricultural industry uses GIS to help identify usable fertile land vs non-fertile land, weather hazards such as flooding or drought, and water supply.\nDevelopment and Urban Planning\n\nPlanners and developers rely on GIS to help them factor in several components when looking to build and develop an area. For example, they use GIS to find empty lots and determine resource and infrastructure availability and needs.\n\nGIS helps plan roads, housing, schools, businesses, government spaces, and hospitals. It also stores historical data, including ageing infrastructure, monuments, wetland areas, protected habitats, and species.\n\nAnother important factor is soil mapping, identifying possible hazards such as flooding, volcanic activity or other environmental issues.\nHealthcare\n\nToday, healthcare sectors use GIS to track disease patterns, whether an outbreak, an epidemic, cancer hotspots, or people in a specific location suffering from an environmentally caused illness. \n\nGIS has a disease surveillance system that can conduct a spatial analysis to locate which area is high-risk, and the GIS software is better are validating data.\nInsurance Companies\n\nMitigating and understanding risks ahead of time is essential to insurance companies, and they use GIS to ensure they are aware of possible dangers before giving you a quote.",

        "answer": "This improvement is due primarily to the modeling of the context.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use.

It oscillates with a regular period of 3-6 min. After a meal the amplitude of these oscillations increases but the periodicity remains constant. The oscillations are believed to be important for insulin sensitivity by preventing downregulation of insulin receptors in target cells. Such downregulation underlies insulin resistance, which is common in type 2 diabetes. It would therefore be advantageous to administer insulin to diabetic patients in a manner mimicking the natural oscillations. The insulin oscillations are generated by pulsatile release of the hormone from the pancreas. Insulin originates from beta cells located in the islets of Langerhans. Since each islet contains up to 2000 beta cells and there are one million islets in the pancreas it is apparent that pulsatile secretion requires sophisticated synchronization both within and among the islets of Langerhans.",

Large pupils are an adaptation to dim light. The domestic cat has slit pupils, which allow it to focus bright light without chromatic aberration. At low light, a cat's pupils expand to cover most of the exposed surface of its eyes. The domestic cat has rather poor color vision and only two types of cone cells, optimized for sensitivity to blue and yellowish green; its ability to distinguish between red and green is limited. A response to middle wavelengths from a system other than the rod cells might be due to a third type of cone. This appears to be an adaptation to low light levels rather than representing true trichromatic vision. Cats also have a nictitating membrane, allowing them to blink without hindering their vision.",

        "answer": "It requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well.",
        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nFor one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well.",

        "evidence": "We design LiLi as a combination of two interconnected models: (1) a RL model that learns to formulate a query-specific inference strategy for performing the OKBC task, and (2) a lifelong prediction model to predict whether a triple should be in the KB, which is invoked by an action while executing the inference strategy and is learned for each relation as in C-PR. The framework improves its performance over time through user interaction and knowledge retention. Compared to the existing KB inference methods, LiLi overcomes the following three challenges for OKBC:\n1. Mapping open-world to close-world. Being a closed-world method, C-PR cannot extract path features and learn a prediction model when any of INLINEFORM0 , INLINEFORM1 or INLINEFORM2 is unknown. LiLi solves this problem through interactive knowledge acquisition. If INLINEFORM3 is unknown, LiLi asks the user to provide a clue (an example of INLINEFORM4 ). And if INLINEFORM5 or INLINEFORM6 is unknown, LiLi asks the user to provide a link (relation) to connect the unknown entity with an existing entity (automatically selected) in the KB. We refer to such a query as a connecting link query (CLQ). The acquired knowledge reduces OKBC to KBC and makes the inference task feasible.\n2. Spareseness of KB. A main issue of all PR methods like C-PR is the connectivity of the KB graph. If there is no path connecting INLINEFORM0 and INLINEFORM1 in the graph, path enumeration of C-PR gets stuck and inference becomes infeasible. In such cases, LiLi uses a template relation (“@-?-@\") as the missing link marker to connect entity-pairs and continues feature extraction. A path containing “@-?-@\" is called an incomplete path. Thus, the extracted feature set contains both complete (no missing link) and incomplete paths. Next, LiLi selects an incomplete path from the feature set and asks the user to provide a link for path completion. We refer to such a query as missing link query (MLQ).\n3. Limitation in user knowledge. If the user is unable to respond to MLQs or CLQs, LiLi uses a guessing mechanism (discussed later) to fill the gap. This enables LiLi to continue its inference even if the user cannot answer a system question.\n3. Limitation in user knowledge. If the user is unable to respond to MLQs or CLQs, LiLi uses a guessing mechanism (discussed later) to fill the gap.

        "evidence": "Previous work in computational linguistics and clinical psychology has tended to focus on the detection of mental health issues as classification tasks BIBREF44 . Datasets have been collected for various conditions including BD using publicly available social-media data from Twitter BIBREF45 and Reddit BIBREF46 , BIBREF47 . Unfortunately, the Twitter dataset is unavailable for further research. In both Reddit datasets, mental health-related content was deliberately removed. This allows the training of classifiers that try to predict the mental health of authors from excerpts that do not explicitly address mental health, yet it renders the data useless for analyses on how mental health is talked about online. Due to this lack of appropriate existing publicly accessible datasets, we will create such resources and make them available to subsequent researchers.\nWe plan to collect data relevant for BD in general as well as for personal recovery in BD from three sources varying in their available amount versus depth of the accounts we expect to find: 1) Twitter, 2) Reddit (focusing on mental health-related content unlike previous work), 3) blogs authored by affected individuals. Twitter and Reddit users with a BD diagnosis will be identified automatically via self-reported diagnosis statements, such as `I was diagnosed with BD-I last week'. To do so, we will extend on the diagnosis patterns and terms for BD provided by BIBREF47 . Implicit consent is assumed from users on these platforms to use their public tweets and posts. SECREF3 Relevant blogs will be manually identified, and their authors will be contacted to obtain informed consent for using their texts.\nSince language and culture are important factors in our research questions, we need information on the language of the texts and the country of residence of their authors, which is not provided in a structured format in the three data sources. For language identification, Twitter employs an automatic tool BIBREF48 , which can be used to filter tweets according to 60 language codes, and there are free, fairly accurate tools such as the Google Compact Language Detector, which can be applied to Reddit and blog posts. The location of Twitter users can be automatically inferred from their tweets BIBREF49 or the (albeit noisy) location field in their user profiles BIBREF50 . Only one attempt to classify the location of Reddit users has been published so far BIBREF51 showing meagre results, indicating that the development of robust location classification approaches on this platform would constitute a valuable contribution. Some companies collect mental health-related online data and make them available to researchers subject to approval of their internal review boards, e.g., OurDataHelps by Qntfy or the peer-support forum provider 7 Cups. Unlike `raw' social media data, these datasets have richer user-provided metadata and explicit consent for research usage. On the other hand, less data is available, the process to obtain access might be tedious within the short timeline of a PhD project and it might be impossible to share the used portions of the data with other researchers. Therefore, we will follow up the possibilities of obtaining access to these datasets, but in parallel also collect our own datasets to avoid dependence on external data providers.\nWe plan to collect data relevant for BD in general as well as for personal recovery in BD from three sources varying in their available amount versus depth of the accounts we expect to find: 1) Twitter, 2) Reddit (focusing on mental healthrelated content unlike previous work), 3) blogs authored by affected individuals.",

His biography on the official National Basketball Association (NBA) website states: \"By acclamation, Michael Jordan is the greatest basketball player of all time.\" He played fifteen seasons in the NBA, winning six NBA championships with the Chicago Bulls. Jordan is the principal owner and chairman of the Charlotte Hornets of the NBA and of 23XI Racing in the NASCAR Cup Series. He was integral in popularizing the basketball sport and the NBA around the world in the 1980s and 1990s, becoming a global cultural icon.\n\nJordan played college basketball for three seasons under coach Dean Smith with the North Carolina Tar Heels. As a freshman, he was a member of the Tar Heels' national championship team in 1982. Jordan joined the Bulls in 1984 as the third overall draft pick, and quickly emerged as a league star, entertaining crowds with his prolific scoring while gaining a reputation as one of the game's best defensive players. His leaping ability, demonstrated by performing slam dunks from the free-throw line in Slam Dunk Contests, earned him the nicknames \"Air Jordan\" and \"His Airness\". Jordan won his first NBA title with the Bulls in 1991, and followed that achievement with titles in 1992 and 1993, securing a three-peat. Jordan abruptly retired from basketball before the 1993–94 NBA season to play Minor League Baseball but returned to the Bulls in March 1995 and led them to three more championships in 1996, 1997, and 1998, as well as a then-record 72 regular season wins in the 1995–96 NBA season. He retired for the second time in January 1999 but returned for two more NBA seasons from 2001 to 2003 as a member of the Washington Wizards. During the course of his professional career he was also selected to play for the United States national team, winning four gold medals (at the 1983 Pan American Games, 1984 Summer Olympics, 1992 Tournament of the Americas and 1992 Summer Olympics), while also being undefeated.",

The present work focuses on the narrow but important problem of unsupervised Acoustic Unit Discovery (AUD). It takes place as the continuation of an ongoing effort to develop a Bayesian model suitable for this task, which stems from the seminal work of BIBREF0 later refined and made scalable in BIBREF1 . This model, while rather crude, has shown that it can provide a clustering accurate enough to be used in topic identification of spoken document in unknown languages BIBREF2 . It was also shown that this model can be further improved by incorporating a Bayesian \"phonotactic\" language model learned jointly with the acoustic units BIBREF3 .

        "evidence": "Extractive multi-document summarization (MDS) aims to summarize a collection of documents by selecting a small number of sentences that represent the original content appropriately. Typical objectives for assembling a summary include information coverage and non-redundancy. A wide variety of methods have been introduced to approach MDS.\nMany approaches are based on sentence ranking, i.e. assigning each sentence a score that indicates how well the sentence summarizes the input BIBREF0 , BIBREF1 , BIBREF2 . A summary is created by selecting the top entries of the ranked list of sentences. Since the sentences are often treated separately, these models might allow redundancy in the summary. Therefore, they are often extended by an anti-redundancy filter while de-queuing ranked sentence lists.\nOther approaches work at summary-level rather than sentence-level and aim to optimize functions of sets of sentences to find good summaries, such as KL-divergence between probability distributions BIBREF3 or submodular functions that represent coverage, diversity, etc. BIBREF4 \nThe centroid-based model belongs to the former group: it represents sentences as bag-of-word (BOW) vectors with TF-IDF weighting and uses a centroid of these vectors to represent the whole document collection BIBREF5 . The sentences are ranked by their cosine similarity to the centroid vector. This method is often found as a baseline in evaluations where it usually is outperformed BIBREF0 , BIBREF6 .\nThis baseline can easily be adapted to work at the summary-level instead the sentence level. This is done by representing a summary as the centroid of its sentence vectors and maximizing the similarity between the summary centroid and the centroid of the document collection. A simple greedy algorithm is used to find the best summary under a length constraint.\nIn order to keep the method efficient, we outline different methods to select a small number of candidate sentences from each document in the input collection before constructing the summary.\nWe test these modifications on the DUC2004 dataset for multi-document summarization. The results show an improvement of Rouge scores over the original centroid method. The performance is on par with state-of-the-art methods which shows that the similarity between a summary centroid and the input centroid is a well-suited function for global summary optimization.\nThe summarization approach presented in this paper is fast, unsupervised and simple to implement. Nevertheless, it performs as well as more complex state-of-the-art approaches in terms of Rouge scores on the DUC2004 dataset. It can be used as a strong baseline for future research or as a fast and easy-to-deploy summarization tool.\nWe test these modifications on the DUC2004 dataset for multi-document summarization.",

Over this dataset, we compare the methodology suggested here to those reported by BIBREF1, BIBREF4. As the latter report overall accuracy of their binary prediction, we convert our controversiality estimates to a binary classification by classifying the higher-scored half as controversial, and the lower half as non-controversial.\nDataset II is based on a more recent version of the Wikipedia list of controversial issues (May 2017). As positive examples we take, from this list, all concepts which appear more than 50 times in Wikipedia. This leaves 608 controversial Wikipedia concepts. For negative examples, we follow BIBREF1, BIBREF4 and select a like number of concepts at random. Here too, since each concept only has a binary label, we convert our estimation into a binary classification, and report accuracy.\nDataset III is extracted from 3561 concepts whose Wikipedia pages are under edit protection, assuming that many of them are likely to be controversial. They were then crowd-annotated, with 10 or more annotators per concept. The annotation instructions were: “Given a topic and its description on Wikipedia, mark if this is a topic that people are likely to argue about.”. Average pairwise kappa agreement on this task was 0.532. Annotations were normalized to controversiality scores on an integer scale of 0 - 10. We used this dataset for testing the models trained on Dataset I.\nIn all datasets, to obtain the sentence-level context of the concepts (positive and negative), we randomly select two equal-sized sets of Wikipedia sentences, that explicitly reference these concepts – i.e., that contain a hyperlink to the article titled by the concept. Importantly, in each sentence we mask the words that reference the concept – i.e., the surface form of the hyperlink leading to the concept – by a fixed, singular token, thus focusing solely on the context within which the concepts are mentioned.\nWe consider three datasets, two of which are a contribution of this work.",

        "question": "By applying semi-supervised learning, what can be available？",
        "answer": "Allowing them to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming.",
        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nThird, we also apply semi-supervised learning, allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming.",

The problem of SHOT is that it directly trains the feature extractor of the large source model during model adaptation, and thus causes large memory footprint. To reduce the memory footprint during model adaptation, we develop lite residual hypothesis transfer as follows.

        "evidence": "In this paper, a source-target unified knowledge distillation (STU-KD) scheme was developed to adapt the compact model on the edge device to the target data while protecting users' privacy. In the scheme, a large source model was first loaded and adapted to the target data on the edge device, and a large target model was obtained. Such an adaptation was enabled by a memory efficient lite residual hypothesis transfer algorithm. A collaborative knowledge distillation method that unifies the target data and the source data for training the compact model was developed to transfer the knowledge of the large target model to the compact model while preventing catastrophic forgetting. Secure aggregation was also employed in STU-KD to enhance privacy preservation. Extensive experiments showed that STU-KD can achieve the highest inference accuracy over the target data while maintaining the original high inference accuracy over the source data, compared with stateof-the-art schemes. STU-KD is now evaluated on public datasets. How to incorporate STU-KD into a real-world application can be an interesting topic for future work.\nTo boost the inference accuracy of the compact model, a large source model with sufficient model capacity, defined as a function f T , is adopted in STU-KD. It can learn more fine-grained representations of the target data compared with the compact model. Before being deployed to the M edge devices, the large source model f T is pretrained over the source data by minimizing an objective function J T (w T ) = E (xs,ys) [L(f T (x s ; w T ), y s )], where w T denotes the parameters of the large source model, and L(•, •) is the standard cross-entropy loss. On edge device m ∈ {1, ..., M }, the large source model is then adapted to the target data. The challenges of the adaptation are twofold. First, the target data are unlabeled so that fine-grained representations of the target data cannot be learned via supervised learning. As a result, unsupervised domain adaptation (UDA) is needed. Second, edge device m does not have the source data, so many UDA methods are not feasible for the adaptation. Thus, source-free UDA methods) must be employed. However, existing source-free UDA methods, e.g., source hypothesis transfer (SHOT), require retraining of the large source model, which leads to large memory consumption on the edge device.\nTo tackle the above challenges of the adaptation, a memory-efficient UDA method called lite residual hypothesis transfer (LRHT) is designed by enhancing the architecture of a source-free UDA method such as SHOT. LRHT adopts the same loss function as that of SHOT (denoted as J S in Figure), so unsupervised learning can be conducted over the unlabeled target data. The details of the loss function of SHOT are provided in Appendix A. However, the feature extractor in SHOT must be replaced with a new architecture that can be trained in a memory-efficient manner. As shown in Figure, the new architecture is designed by adding lite residual (LR) modules to the feature extractor such that its outputs can be fine-tuned by the LR modules. The LR modules fine-tune the outputs of the feature extractor by changing the intermediate activations of the feature extractor. Define the i-th building block of the feature extractor as a function g i and the LR module added to the it as a function r i . Given the activations a i−1 of the (i − 1)-th building block, LR module r i changes the activations of the i-th building block as a i = g i (a i−1 ) + r i (a i−1 ), where g i (a i−1 ) denotes the original activations of the i-th building block, and r i (a i−1 ) denotes the residual activations of LR module r i . During the adaptation, the parameters of the feature extractor and that of the classifier are fixed, and only the LR modules are trained to fine-tune the outputs of the feature extractor. Compared to the case of directly training the feature extractor (like SHOT), training the LR modules generates a much smaller volume of activations and demands much lower memory footprint.

        "evidence": "London Underground's eleven lines total 402 kilometres (250 mi) in length, making it the seventh longest metro system in the world. These are made up of the sub-surface network and the deep-tube lines. The Circle, District, Hammersmith & City, and Metropolitan lines form the sub-surface network, with railway tunnels just below the surface and of a similar size to those on British main lines, converging on a circular bi-directional loop around zone 1. The Hammersmith & City and Circle lines share stations and most of their track with each other, as well as with the Metropolitan and District lines. The Bakerloo, Central, Jubilee, Northern, Piccadilly, Victoria and Waterloo & City lines are deep-level tubes, with smaller trains that run in two circular tunnels (tubes) with a diameter about 11 feet 8 inches (3.56 m). These lines have the exclusive use of a pair of tracks, except for the Uxbridge branch of the Piccadilly line, which shares track with the District line between Acton Town and Hanger Lane Junction and with the Metropolitan line between Rayners Lane and Uxbridge; and the Bakerloo line, which shares track with London Overground's Watford DC Line for its aboveground section north of Queen's Park.\n\nFifty-five per cent of the system runs on the surface. There are 20 miles (32 km) of cut-and-cover tunnel and 93 miles (150 km) of tube tunnel. Many of the central London underground stations on deep-level tube routes are higher than the running lines to assist deceleration when arriving and acceleration when departing. Trains generally run on the left-hand track. In some places, the tunnels are above each other (for example, the Central line east of St Paul's station), or the running tunnels are on the right (for example on the Victoria line between Warren Street and King's Cross St. Pancras, to allow cross-platform interchange with the Northern line at Euston).\n\nThe lines are electrified with a four-rail DC system: a conductor rail between the rails is energised at −210 V and a rail outside the running rails at +420 V, giving a potential difference of 630 V. On the sections of line shared with mainline trains, such as the District line from East Putney to Wimbledon and Gunnersbury to Richmond, and the Bakerloo line north of Queen's Park, the centre rail is bonded to the running rails.\n\nThe average speed on the Underground is 20.5 mph (33.0 km/h). Outside the tunnels of central London, many lines' trains tend to travel at over 40 mph (64 km/h) in the suburban and countryside areas. The Metropolitan line can reach speeds of 62 mph (100 km/h).",

        "question": "Why do the authors only share the annotations with researchers that demonstrate a genuine need for them?",
        "answer": "Because the (automatic) annotation of demographic variables in parts of the dataset constitutes especially sensitive information on minority status in conjunction with mental health.",
        "evidence": "Ethical considerations are established as essential part in planning mental health research and most research projects undergo approval by an ethics committee. On the contrary, the computational linguistics community has started only recently to consider ethical questions BIBREF72 , BIBREF73 . Likely, this is because computational linguistics was traditionally concerned with publicly available, impersonal texts such as newspapers or texts published with some temporal distance, which left a distance between the text and author. Conversely, recent social media research often deals with highly personal information of living individuals, who can be directly affected by the outcomes BIBREF72 .\n BIBREF72 discuss issues that can arise when constructing datasets from social media and conducting analyses or developing predictive models based on these data, which we review here in relation to our project: Demographic bias in sampling the data can lead to exclusion of minority groups, resulting in overgeneralisation of models based on these data. As discussed in the introduction, personal recovery research suffers from a bias towards English-speaking Western individuals of white ethnicity. By studying multilingual accounts of ethnically diverse populations we explicitly address the demographic bias of previous research. Topic overexposure is tricky to address, where certain groups are perceived as abnormal when research repeatedly finds that their language is different or more difficult to process. Unlike previous research BIBREF45 , BIBREF47 , BIBREF46 our goal is not to reveal particularities in the language of individuals affected by mental health problems. Instead, we will compare accounts of individuals with BD from different settings (structured interviews versus informal online discourse) and of different backgrounds. While the latter bears the risk to overexpose certain minority groups, we will pay special attention to this in the dissemination of our results.\nLastly, most research, even when conducted with the best intentions, suffers from the dual-use problem BIBREF74 , in that it can be misused or have consequences that affect people's life negatively. For this reason, we refrain from publishing mental health classification methods, which could be used, for example, by health insurance companies for the risk assessment of applicants based on their social media profiles.\nIf and how informed consent needs to be obtained for research on social media data is a debated issue BIBREF75 , BIBREF76 , BIBREF77 , mainly because it is not straightforward to determine if posts are made in a public or private context. From a legal point of view, the privacy policies of Twitter and Reddit, explicitly allow analysis of the user contents by third party, but it is unclear to what extent users are aware of this when posting to these platforms BIBREF78 . However, in practice it is often infeasible to seek retrospective consent from hundreds or thousands of social media users. According to current ethical guidelines for social media research BIBREF79 , BIBREF80 and practice in comparable research projects BIBREF81 , BIBREF78 , it is regarded as acceptable to waive explicit consent if the anonymity of the users is preserved. Therefore, we will not ask the account holders of Twitter and Reddit posts included in our datasets for their consent.\n BIBREF79 formulate guidelines for ethical social media health research that pertain especially to data collection and sharing. In line with these, we will only share anonymised and paraphrased excerpts from the texts, as it is often possible to recover a user name via a web search for the verbatim text of a post. However, we will make the original texts available as datasets to subsequent research under a data usage agreement. Since the (automatic) annotation of demographic variables in parts of our dataset constitutes especially sensitive information on minority status in conjunction with mental health, we will only share these annotations with researchers that demonstrate a genuine need for them, i.e. to verify our results or to investigate certain research questions.\nAnother important question is in which situations of encountering content indicative of a risk of self-harm or harm to others it would be appropriate or even required by duty of care for the research team to pass on information to authorities. Surprisingly, we could only find two mentions of this issue in social media research BIBREF81 , BIBREF82 . Acknowledging that suicidal ideation fluctuates BIBREF83 , we accord with the ethical review board's requirement in BIBREF81 to only analyse content posted at least three months ago. If the research team, which includes clinical psychologists, still perceives users at risk we will make use of the reporting facilities of Twitter and Reddit.\nAs a central component we consider the involvement of individuals with lived experience in our project, an aspect which is missing in the discussion of ethical social media health research so far. The proposal has been presented to an advisory board of individuals with a BD diagnosis and was received positively. The advisory board will be consulted at several stages of the project to inform the research design, analysis, and publication of results. We believe that board members can help to address several of the raised ethical problems, e.g., shaping the research questions to avoid feeding into existing biases or overexposing certain groups and highlighting potentially harmful interpretations and uses of our results.\nSince the (automatic) annotation of demographic variables in parts of our dataset constitutes especially sensitive information on minority status in conjunction with mental health, we will only share these annotations with researchers that demonstrate a genuine need for them, i.e. to verify our results or to investigate certain research questions.",

        "evidence": "Named entity recognition (NER) BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc. NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction BIBREF4 , machine translation BIBREF5 , question answering BIBREF6 and knowledge base construction BIBREF7 . Although early NER systems have been successful in producing adequate recognition accuracy, they often require significant human effort in carefully designing rules or features.\nIn recent years, deep learning methods been employed in NER systems, yielding state-of-the-art performance. However, the number of types detected are still not sufficient for certain domain-specific applications. For relation extraction, identifying fine-grained types has been shown to significantly increase the performance of the extractor BIBREF8 , BIBREF9 since this helps in filtering out candidate relation types which do not follow this type constraint. Furthermore, for question answering fine-grained Named Entity Recognition (FgNER) can provide additional information helping to match questions to its potential answers thus improving performance BIBREF10 . For example, Li and Roth BIBREF11 rank questions based on their expected answer types (i.e. will the answer be food, vehicle or disease).\nTypically, FgNER systems use over a hundred labels, arranged in a hierarchical structure. We find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process. Furthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task. Currently, FgNER systems use distant supervision BIBREF12 to automatically generate training data. Distant supervision is a technique which maps each entity in the corpus to knowledge bases such as Freebase BIBREF13 , DBpedia BIBREF14 , YAGO BIBREF15 and helps with the generation of labeled data. This method will assign the same set of labels to all mentions of a particular entity in the corpus. For example, “Barack Obama” is a person, politician, lawyer, and author. If a knowledge base has these four matching labels, the distant supervision technique will assign all of them to every mention of “Barack Obama”. Therefore, the training data will also fail to distinguish between mentions of “Barack Obama” in all subsequent utterances.\nLing et al. ling2012fine proposed the first system for FgNER, where they used 112 overlapping labels with a linear classifier perceptron for multi-label classification. Yosef et al. spaniol2012hyena used multiple binary SVM classifiers to assign entities to a set of 505 types. Gillick et al. gillick2014context introduced context dependent FgNER and proposed a set of heuristics for pruning labels that might not be relevant given the local context of the entity. Yogatama et al. yogatama2015embedding proposed an embedding based model where user-defined features and labels were embedded into a low dimensional feature space to facilitate information sharing among labels.\nShimaoka et al. shimaoka2016attentive proposed an attentive neural network model which used long short-term memory (LSTMs) to encode the context of the entity, then used an attention mechanism to allow the model to focus on relevant expressions in the entity mention's context. To learn entity representations, we propose a scheme which is potentially more generalizable.\nWe find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process.",

        "evidence": "With the growth of the internet in the last decades, users are faced with an increasing amount of information and have to find ways to summarize it. However, producing summaries in a multi-document setting is a challenging task; the language used to display the same information in a sentence can vary significantly, making it difficult for summarization models to capture. Thus large corpora are needed to develop efficient models. There exist two types of summarization: extractive and abstractive. Extractive summarization outputs summaries in two steps, namely via sentence ranking, where an importance score is assigned to each sentence, and via the subsequent sentence selection, where the most appropriate sentence is chosen. In abstractive summarization, summaries are generated word by word auto-regressively, using sequence-to-sequence or language models. Given the complexity of multi-document summarization and the lack of datasets, most researchers use extractive summarization and rely on hand-crafted features or additional annotated data, both needing human expertise.\nTo our knowledge, wiki2018 is the only work that has proposed a large dataset for multi-document summarization. By considering Wikipedia entries as a collection of summaries on various topics given by their title (e.g., Machine Learning, Stephen King), they create a dataset of significant size, where the lead section of an article is defined as the reference summary and input documents are a mixture of pages obtained from the article's reference section and a search engine. While this approach benefits from the large number of Wikipedia articles, in many cases, articles contain only a few references that tend to be of the desired high quality, and most input documents end up being obtained via a search engine, which results in noisy data. Moreover, at testing time no references are provided, as they have to be provided by human contributors. wiki2018 showed that in this case, generated summaries based on search engine results alone are of poor quality and cannot be used.\nIn contrast, we propose a novel domain-specific dataset containing $14\\,652$ samples, based on professional video game reviews obtained via Metacritic and gameplay sections from Wikipedia. By using Metacritic reviews in addition to Wikipedia articles, we benefit from a number of factors. First, the set of aspects used to assess a game is limited and consequently, reviews share redundancy. Second, because they are written by professional journalists, reviews tend to be in-depth and of high-quality. Additionally, when a video game is released, journalists have an incentive to write a complete review and publish it online as soon as possible to draw the attention of potential customers and increase the revenue of their website BIBREF0. Therefore, several reviews for the same product become quickly available and the first version of the corresponding Wikipedia page is usually made available shortly after. Lastly, reviews and Wikipedia pages are available in multiple languages, which opens up the possibility for multilingual multi-document summarization.\nIn contrast, we propose a novel domain-specific dataset containing $14\\,652$ samples, based on professional video game reviews obtained via Metacritic and gameplay sections from Wikipedia.",

        "evidence": "The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ nearly 130,000 people at its peak and cost nearly US$2 billion (equivalent to about $24 billion in 2021). Over 90 percent of the cost was for building factories and to produce fissile material, with less than 10 percent for development and production of the weapons. Research and production took place at more than thirty sites across the United States, the United Kingdom, and Canada.\n\nThe project led to the development of two types of atomic bombs, both developed concurrently, during the war: a relatively simple gun-type fission weapon and a more complex implosion-type nuclear weapon. The Thin Man gun-type design proved impractical to use with plutonium, so a simpler gun-type design called Little Boy was developed that used uranium-235, an isotope that makes up only 0.7 percent of natural uranium. Because it is chemically identical to the most common isotope, uranium-238, and has almost the same mass, separating the two proved difficult. Three methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this work was carried out at the Clinton Engineer Works at Oak Ridge, Tennessee.\n\nIn parallel with the work on uranium was an effort to produce plutonium, which researchers at the University of California, Berkeley, discovered in 1940. After the feasibility of the world's first artificial nuclear reactor, the Chicago Pile-1, was demonstrated in 1942 at the Metallurgical Laboratory in the University of Chicago, the project designed the X-10 Graphite Reactor at Oak Ridge and the production reactors at the Hanford Site in Washington state, in which uranium was irradiated and transmuted into plutonium. The plutonium was then chemically separated from the uranium, using the bismuth phosphate process. The Fat Man plutonium implosion-type weapon was developed in a concerted design and development effort by the Los Alamos Laboratory.\n\nThe project was also charged with gathering intelligence on the German nuclear weapon project. Through Operation Alsos, Manhattan Project personnel served in Europe, sometimes behind enemy lines, where they gathered nuclear materials and documents, and rounded up German scientists. Despite the Manhattan Project's tight security, Soviet atomic spies successfully penetrated the program.\n\nThe first nuclear device ever detonated was an implosion-type bomb during the Trinity test, conducted at New Mexico's Alamogordo Bombing and Gunnery Range on 16 July 1945. Little Boy and Fat Man bombs were used a month later in the atomic bombings of Hiroshima and Nagasaki, respectively, with Manhattan Project personnel serving as bomb assembly technicians and weaponeers on the attack aircraft. In the immediate postwar years, the Manhattan Project conducted weapons testing at Bikini Atoll as part of Operation Crossroads, developed new weapons, promoted the development of the network of national laboratories, supported medical research into radiology and laid the foundations for the nuclear navy. It maintained control over American atomic weapons research and production until the formation of the United States Atomic Energy Commission in January 1947.",
        "answer": "The Manhattan Project was the program based in the United States which tried to make the first nuclear weapons. The project cost $2 billion, and created many secret cities and bomb-making factories, such as a laboratory in Los Alamos, New Mexico, a nuclear reactor in Hanford, Washington, and a uranium processing plant in Oak Ridge, Tennessee. The top scientist on the project was Robert Oppenheimer, a famous physicist. The Manhattan Project had to find solutions to two difficulties. The first difficulty is how to make the special isotopes of uranium (uranium-235) or plutonium. This process is called separation and is very slow. The United States built very big buildings with three different kinds of machine for separation. They made enough fissionable special isotopes for a few nuclear weapons. The second difficulty was how to make a bomb that will produce a big nuclear explosion every time. A weapon with a bad design can make a much smaller nuclear explosion. This is called a \"fizzle\". In July 1945, the Manhattan Project solved the two difficulties and made the first nuclear explosion. This test of a nuclear weapon was called \"Trinity\" and was a success.

Only in the realm of vocal composition – opera and the mass – was his effect on later generations muted.\n\nBeethoven's stylistic innovations bridge the Classical and Romantic periods. The works of his early period brought the Classical form to its highest expressive level, expanding in formal, structural, and harmonic terms the musical idiom developed by predecessors such as Mozart and Haydn. The works of his middle period were more forward-looking, contributing to the musical language and thinking of the Romantic era, inspiring composers such as Franz Schubert, Felix Mendelssohn, Robert Schumann, Franz Liszt, Richard Wagner, and Johannes Brahms. His late period works were characterized by formal, harmonic, and structural experimentation at the highest level, often pointing toward contrapuntal tendencies and microscopic textures, as well as an increasingly introverted compositional outlook.

        "evidence": "Today, the most popular method for training multi-layer perceptrons (MLPs) is back-propagation. The terminology \"back-propagating errors\" was introduced in 1962 by Frank Rosenblatt, but he did not know how to implement this, although Henry J. Kelley had a continuous precursor of backpropagation already in 1960 in the context of control theory. Modern backpropagation is actually Seppo Linnainmaa's general reverse mode of automatic differentiation (1970) for discrete connected networks of nested differentiable functions. It is an efficient application of the chain rule (derived by Gottfried Wilhelm Leibniz in 1673) to networks of differentiable nodes. In 1982, Paul Werbos applied backpropagation to MLPs in the way that has become standard. In 1985, David E. Rumelhart et al. published an experimental analysis of the technique. Many improvements have been implemented in subsequent decades.\n\nDuring backpropagation, the output values are compared with the correct answer to compute the value of some predefined error-function. The error is then fed back through the network. Using this information, the algorithm adjusts the weights of each connection in order to reduce the value of the error function by some small amount. After repeating this process for a sufficiently large number of training cycles, the network will usually converge to some state where the error of the calculations is small. In this case, one would say that the network has learned a certain target function. To adjust weights properly, one applies a general method for non-linear optimization that is called gradient descent, due to Augustin-Louis Cauchy, who first suggested it in 1847. For this, the network calculates the derivative of the error function with respect to the network weights, and changes the weights such that the error decreases (thus going downhill on the surface of the error function). For this reason, back-propagation can only be applied on networks with differentiable activation functions.",

During training, we generate adversarial examples with the current model as the target and update the model parameters with the hybrid batch iteratively. The beam size for generation is set to 1 to reduce the computation cost, since the generation success rate is minor in adversarial training. We evaluate the adversarially trained models, as shown in Table TABREF18.\nAfter adversarial training, the performance of all the target models raises significantly, while that on the original examples remain comparable.

        "question": "What social platforms are the first-hand accounts from?",
        "answer": "They are from blog posts, tweets, and discussion forums.",
        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nConcurrently, it has been argued for mental health research that it would constitute a ‘valuable critical step’ (Stuart et al., 2017) to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums.",

These components are combined to form a filter network and are most often placed between the full frequency-range power amplifier and the loudspeaker drivers to divide the amplifier's signal into the necessary frequency bands before being delivered to the individual drivers. Passive crossover circuits need no external power beyond the audio signal itself, but have some disadvantages: they may require larger inductors and capacitors due to power handling requirements. Unlike active crossovers which include a built-in amplifier, passive crossovers have an inherent attenuation within the passband, typically leading to a reduction in damping factor before the voice coil",

        "evidence": "While there are a large number of sorting algorithms, in practical implementations a few algorithms predominate. Insertion sort is widely used for small data sets, while for large data sets an asymptotically efficient sort is used, primarily heapsort, merge sort, or quicksort. Efficient implementations generally use a hybrid algorithm, combining an asymptotically efficient algorithm for the overall sort with insertion sort for small lists at the bottom of a recursion. Highly tuned implementations use more sophisticated variants, such as Timsort (merge sort, insertion sort, and additional logic), used in Android, Java, and Python, and introsort (quicksort and heapsort), used (in variant forms) in some C++ sort implementations and in .NET.\n\nFor more restricted data, such as numbers in a fixed interval, distribution sorts such as counting sort or radix sort are widely used. Bubble sort and variants are rarely used in practice, but are commonly found in teaching and theoretical discussions.\n\nWhen physically sorting objects (such as alphabetizing papers, tests or books) people intuitively generally use insertion sorts for small sets. For larger sets, people often first bucket, such as by initial letter, and multiple bucketing allows practical sorting of very large sets. Often space is relatively cheap, such as by spreading objects out on the floor or over a large area, but operations are expensive, particularly moving an object a large distance – locality of reference is important. Merge sorts are also practical for physical objects, particularly as two hands can be used, one for each list to merge, while other algorithms, such as heapsort or quicksort, are poorly suited for human use. Other algorithms, such as library sort, a variant of insertion sort that leaves spaces, are also practical for physical use.",

        "evidence": "Online social networks have become one of the most disruptive communication platforms, as everyday billions of individuals use them to interact with each other. Their penetration in our everyday lives seems ever-growing and has in turn generated a massive volume of publicly available data open to analysis. The digital footprints left across these multiple media platforms provide us with a unique source to study and understand how the linguistic phenotype of a given user is related to social attributes such as socioeconomic status (SES).\nThe quantification and inference of SES of individuals is a long lasting question in the social sciences. It is a rather difficult problem as it may depend on a combination of individual characteristics and environmental variables BIBREF0 . Some of these features can be easier to assess like income, gender, or age whereas others, relying to some degree on self-definition and sometimes entangled with privacy issues, are harder to assign like ethnicity, occupation, education level or home location. Furthermore, individual SES correlates with other individual or network attributes, as users tend to build social links with others of similar SES, a phenomenon known as status homophily BIBREF1 , arguably driving the observed stratification of society BIBREF2 . At the same time, shared social environment, similar education level, and social influence have been shown to jointly lead socioeconomic groups to exhibit stereotypical behavioral patterns, such as shared political opinion BIBREF3 or similar linguistic patterns BIBREF4 . Although these features are entangled and causal relation between them is far from understood, they appear as correlations in the data.\nDatasets recording multiple characteristics of human behaviour are more and more available due to recent developments in data collection technologies and increasingly popular online platforms and personal digital devices. The automatic tracking of online activities, commonly associated with profile data and meta-information; the precise recording of daily activities, interaction dynamics and mobility patterns collected through mobile personal devices; together with the detailed and expert annotated census data all provide new grounds for the inference of individual features or behavioral patterns BIBREF5 . The exploitation of these data sources has already been proven to be fruitful as cutting edge recommendation systems, advanced methods for health record analysis, or successful prediction tools for social behaviour heavily rely on them BIBREF6 . Nevertheless, despite the available data, some inference tasks, like individual SES prediction, remain an open challenge.\nThe precise inference of SES would contribute to overcome several scientific challenges and could potentially have several commercial applications BIBREF7 . Further, robust SES inference would provide unique opportunities to gain deeper insights on socioeconomic inequalities BIBREF8 , social stratification BIBREF2 , and on the driving mechanisms of network evolution, such as status homophily or social segregation.\nIn this work, we take a horizontal approach to this problem and explore various ways to infer the SES of a large sample of social media users. We propose different data collection and combination strategies using open, crawlable, or expert annotated socioeconomic data for the prediction task. Specifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations. Individual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations. Each of these datasets is then used as ground-truth to infer the SES of Twitter users from profile and semantic features similar to BIBREF9 . We aim to explore and assess how the SES of social media users can be obtained and how much the inference problem depends on annotation and the user's individual and linguistic attributes.\nWe provide in Section SECREF2 an overview of the related literature to contextualize the novelty of our work. In Section SECREF3 we provide a detailed description of the data collection and combination methods. In Section SECREF4 we introduce the features extracted to solve the SES inference problem, with results summarized in Section SECREF5 . Finally, in Section SECREF6 and SECREF7 we conclude our paper with a brief discussion of the limitations and perspectives of our methods.\nSpecifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations.",

In fact, online harassment becomes very common in Twitter and there have been a lot of critics that Twitter has become the platform for many racists, misogynists and hate groups which can express themselves openly. Online harassment is usually in the form of verbal or graphical formats and is considered harassment, because it is neither invited nor has the consent of the receipt. Monitoring the contents including sexism and sexual harassment in traditional media is easier than monitoring on the online social media platforms like Twitter. The main reason is because of the large amount of user generated content in these media. So, the research about the automated detection of content containing sexual harassment is an important issue and could be the basis for removing that content or flagging it for human evaluation. The basic goal of this automatic classification is that it will significantly improve the process of detecting these types of hate speech on social media by reducing the time and effort required by human beings.\nPrevious studies have been focused on collecting data about sexism and racism in very broad terms or have proposed two categories of sexism as benevolent or hostile sexism BIBREF0, which undermines other types of online harassment. However, there is no much study focusing on different types online harassment alone attracting natural language processing techniques.\nIn this paper we present our work, which is a part of the SociaL Media And Harassment Competition of the ECML PKDD 2019 Conference. The topic of the competition is the classification of different types of harassment and it is divided in two tasks.

        "evidence": "The encoder-decoder based framework BIBREF0, BIBREF1, BIBREF2 is the dominant approach for neural machine translation (NMT) BIBREF3, BIBREF4. Although the encoder and decoder usually adopt the same model structure (RNN BIBREF5, CNN BIBREF6 or self-attention BIBREF3, BIBREF7) and the same number of layers, they perform different functionalities: the encoder extracts the hidden representations of the source sentence, and the decoder generates target tokens conditioned on the source hidden representations as well as the previous generated tokens.\nWhile most existing works focus on the design and improvement of encoder-decoder framework for NMT BIBREF8, BIBREF6, BIBREF3, BIBREF9 as well as its detailed analyses BIBREF10, BIBREF11, BIBREF12, BIBREF13, few works concentrate on the characteristics and functionalities of the encoder and the decoder, which are valuable to understand this popular framework and improve its performance in NMT. Therefore, in this paper, we conduct a study and aim to understand the characteristics of the encoder and the decoder in NMT. We observe some interesting phenomena:\nThe decoder handles an easier task than the encoder. 1) We find that adding more layers to the encoder achieves larger improvements than adding more layers to the decoder. 2) We also compare the training time of the encoder and decoder by fixing the parameters of a well-trained decoder (encoder), and just update the parameters of the encoder (decoder). We found that the decoder converges faster than the encoder. These two results suggest that the decoder handles an easier task than the encoder in NMT.\nThe decoder is more sensitive to the input noise than the encoder. We randomly add different level of noise to the input of the encoder and decoder respectively during inference, and find that adding noise to the input of the decoder leads to better accuracy drop than that of the encoder.\nWe further analyze why the decoder is more sensitive by masking the previous tokens, and comparing autoregressive NMT with the non-autoregressive counterpart. We find that the preceding tokens in the decoder provide strong conditional information, which partially explain the previous two observations on the decoder.\nWe believe our studies on the different characteristics of the encoder and decoder will inspire the following research on the encoder-decoder framework as well as improve the performance on NMT and other encoder-decoder based tasks.\nWe find that adding more layers to the encoder achieves larger improvements than adding more layers to the decoder.",

        "evidence": "Several recent papers have described approaches for learning deep communicating policies (DCPs): decentralized representations of behavior that enable multiple agents to communicate via a differentiable channel that can be formulated as a recurrent neural network. DCPs have been shown to solve a variety of coordination problems, including reference games BIBREF0 , logic puzzles BIBREF1 , and simple control BIBREF2 . Appealingly, the agents' communication protocol can be learned via direct backpropagation through the communication channel, avoiding many of the challenging inference problems associated with learning in classical decentralized decision processes BIBREF3 .\nBut analysis of the strategies induced by DCPs has remained a challenge. As an example, fig:teaser depicts a driving game in which two cars, which are unable to see each other, must both cross an intersection without colliding. In order to ensure success, it is clear that the cars must communicate with each other. But a number of successful communication strategies are possible—for example, they might report their exact $(x, y)$ coordinates at every timestep, or they might simply announce whenever they are entering and leaving the intersection. If these messages were communicated in natural language, it would be straightforward to determine which strategy was being employed. However, DCP agents instead communicate with an automatically induced protocol of unstructured, real-valued recurrent state vectors—an artificial language we might call “neuralese,” which superficially bears little resemblance to natural language, and thus frustrates attempts at direct interpretation.\nWe propose to understand neuralese messages by translating them. In this work, we present a simple technique for inducing a dictionary that maps between neuralese message vectors and short natural language strings, given only examples of DCP agents interacting with other agents, and humans interacting with other humans. Natural language already provides a rich set of tools for describing beliefs, observations, and plans—our thesis is that these tools provide a useful complement to the visualization and ablation techniques used in previous work on understanding complex models BIBREF4 , BIBREF5 .\nWhile structurally quite similar to the task of machine translation between pairs of human languages, interpretation of neuralese poses a number of novel challenges. First, there is no natural source of parallel data: there are no bilingual “speakers” of both neuralese and natural language. Second, there may not be a direct correspondence between the strategy employed by humans and DCP agents: even if it were constrained to communicate using natural language, an automated agent might choose to produce a different message from humans in a given state. We tackle both of these challenges by appealing to the grounding of messages in gameplay. Our approach is based on one of the core insights in natural language semantics: messages (whether in neuralese or natural language) have similar meanings when they induce similar beliefs about the state of the world.\nBased on this intuition, we introduce a translation criterion that matches neuralese messages with natural language strings by minimizing statistical distance in a common representation space of distributions over speaker states. We explore several related questions:\nOur translation model and analysis are general, and in fact apply equally to human–computer and human–human translation problems grounded in gameplay. In this paper, we focus our experiments specifically on the problem of interpreting communication in deep policies, and apply our approach to the driving game in fig:teaser and two reference games of the kind shown in fig:bird-examples. We find that this approach outperforms a more conventional machine translation criterion both when attempting to interoperate with neuralese speakers and when predicting their state.\nBased on this intuition, we introduce a translation criterion that matches neuralese messages with natural language strings by minimizing statistical distance in a common representation space of distributions over speaker states.",

The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a metropolitan statistical area (MSA) home to a census-estimated 4.8 million people in 2016 and ranking as the tenth-largest MSA in the country. \n\nBoston is one of the oldest municipalities in America, founded on the Shawmut Peninsula in 1630 by Puritan settlers from the English town of the same name. It was the scene of several key events of the American Revolution and the nation's founding, such as the Boston Massacre, the Boston Tea Party, the Battle of Bunker Hill, and the siege of Boston. Upon American independence from Great Britain, the city continued to be an important port and manufacturing hub as well as a center for education and culture. The city has expanded beyond the original peninsula through land reclamation and municipal annexation. Its rich history attracts many tourists, with Faneuil Hall alone drawing more than 20 million visitors per year. Boston's many firsts include the United States' first public park (Boston Common, 1634), first public or state school (Boston Latin School, 1635) first subway system (Tremont Street subway, 1897), and first large public library (Boston Public Library, 1848).\n\nToday, Boston is a center of scientific research; the area's many colleges and universities, notably Harvard and MIT, make it a world leader in higher education, including law, medicine, engineering and business, and the city is considered to be a global pioneer in innovation and entrepreneurship, with nearly 5,000 startups.

        "evidence": "The challenges of imbalanced classification—in which the proportion of elements in each class for a classification task significantly differ—and of the ability to generalise on dissimilar data have remained important problems in Natural Language Processing (NLP) and Machine Learning in general. Popular NLP tasks including sentiment analysis, propaganda detection, and event extraction from social media are all examples of imbalanced classification problems. In each case the number of elements in one of the classes (e.g. negative sentiment, propagandistic content, or specific events discussed on social media, respectively) is significantly lower than the number of elements in the other classes.\nThe recently introduced BERT language model for transfer learning BIBREF0 uses a deep bidirectional transformer architecture to produce pre-trained context-dependent embeddings. It has proven to be powerful in solving many NLP tasks and, as we find, also appears to handle imbalanced classification well, thus removing the need to use standard methods of data augmentation to mitigate this problem (see Section SECREF11 for related work and Section SECREF16 for analysis).\nBERT is credited with the ability to adapt to many tasks and data with very little training BIBREF0. However, we show that BERT fails to perform well when the training and test data are significantly dissimilar, as is the case with several tasks that deal with social and news data. In these cases, the training data is necessarily a subset of past data, while the model is likely to be used on future data which deals with different topics. This work addresses this problem by incorporating cost-sensitivity (Section SECREF19) into BERT.\nWe test these methods by participating in the Shared Task on Fine-Grained Propaganda Detection for the 2nd Workshop on NLP for Internet Freedom, for which we achieve the second rank on sentence-level classification of propaganda, confirming the importance of cost-sensitivity when the training and test sets are dissimilar.\nWe show that common (‘easy’) methods of data augmentation for dealing with class imbalance do not improve base BERT performance",

        "answer": "Yes, it does.",
        "evidence": "In natural language processing (NLP), question generation is considered to be an important yet challenging problem. Given a passage and answer as inputs to the model, the task is to generate a semantically coherent question for the given answer.\nIn the past, question generation has been tackled using rule-based approaches such as question templates BIBREF0 or utilizing named entity information and predictive argument structures of sentences BIBREF1. Recently, neural-based approaches have accomplished impressive results BIBREF2, BIBREF3, BIBREF4 for the task of question generation. The availability of large-scale machine reading comprehension datasets such as SQuAD BIBREF5, NewsQA BIBREF6, MSMARCO BIBREF7 etc. have facilitated research in question answering task. SQuAD BIBREF5 dataset itself has been the de facto choice for most of the previous works in question generation. However, 90% of the questions in SQuAD can be answered from a single sentence BIBREF8, hence former QG systems trained on SQuAD are not capable of distilling and utilizing information from multiple sentences. Recently released multi-hop datasets such as QAngaroo BIBREF9, ComplexWebQuestions BIBREF10 and HotPotQA BIBREF11 are more suitable for building QG systems that required to gather and utilize information across multiple documents as opposed to a single paragraph or sentence.\nIn multi-hop question answering, one has to reason over multiple relevant sentences from different paragraphs to answer a given question. We refer to these relevant sentences as supporting facts in the context. Hence, we frame Multi-hop question generation as the task of generating the question conditioned on the information gathered from reasoning over all the supporting facts across multiple paragraphs/documents. Since this task requires assembling and summarizing information from multiple relevant documents in contrast to a single sentence/paragraph, therefore, it is more challenging than the existing single-hop QG task. Further, the presence of irrelevant information makes it difficult to capture the supporting facts required for question generation. The explicit information about the supporting facts in the document is not often readily available, which makes the task more complex. In this work, we provide an alternative to get the supporting facts information from the document with the help of multi-task learning. Table TABREF1 gives sample examples from SQuAD and HotPotQA dataset. It is cleared from the example that the single-hop question is formed by focusing on a single sentence/document and answer, while in multi-hop question, multiple supporting facts from different documents and answer are accumulated to form the question.\nMulti-hop QG has real-world applications in several domains, such as education, chatbots, etc. The questions generated from the multi-hop approach will inspire critical thinking in students by encouraging them to reason over the relationship between multiple sentences to answer correctly. Specifically, solving these questions requires higher-order cognitive-skills (e.g., applying, analyzing). Therefore, forming challenging questions is crucial for evaluating a student’s knowledge and stimulating self-learning. Similarly, in goal-oriented chatbots, multi-hop QG is an important skill for chatbots, e.g., in initiating conversations, asking and providing detailed information to the user by considering multiple sources of information. In contrast, in a single-hop QG, only single source of information is considered while generation.\nIn this paper, we propose to tackle Multi-hop QG problem in two stages. In the first stage, we learn supporting facts aware encoder representation to predict the supporting facts from the documents by jointly training with question generation and subsequently enforcing the utilization of these supporting facts. The former is achieved by sharing the encoder weights with an answer-aware supporting facts prediction network, trained jointly in a multi-task learning framework. The latter objective is formulated as a question-aware supporting facts prediction reward, which is optimized alongside supervised sequence loss. Additionally, we observe that multi-task framework offers substantial improvements in the performance of question generation and also avoid the inclusion of noisy sentences information in generated question, and reinforcement learning (RL) brings the complete and complex question to otherwise maximum likelihood estimation (MLE) optimized QG model.\nOur main contributions in this work are: (i). We introduce the problem of multi-hop question generation and propose a multi-task training framework to condition the shared encoder with supporting facts information. (ii). We formulate a novel reward function, multihop-enhanced reward via question-aware supporting fact predictions to enforce the maximum utilization of supporting facts to generate a question; (iii). We introduce an automatic evaluation metric to measure the coverage of supporting facts in the generated question. (iv). Empirical results show that our proposed method outperforms the current state-of-the-art single-hop QG models over several automatic and human evaluation metrics on the HotPotQA dataset.\nAdditionally, we observe that multi-task framework offers substantial improvements in the performance of question generation and also avoid the inclusion of noisy sentences information in generated question, and reinforcement learning (RL) brings the complete and complex question to otherwise maximum likelihood estimation (MLE) optimized QG model.",

        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nIn particular, we derive connections between the work of Peters et al. who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs.",

Twitter activity consists of short posts called tweets which are limited to 140 characters. Retweets, where users repost a tweet to spread its content, were not considered. (The spread of causal statements will be considered in future work.) We considered only English-language tweets for this study. To avoid cross-language effects, we kept only tweets with a user-reported language of `English' and, as a second constraint, individual tweets needed to match more English stopwords than any other language's set of stopwords. Stopwords considered for each language were determined using NLTK's database BIBREF29 . A tweet will be referred to as a `document' for the rest of this work.\nCausal documents were chosen to contain one occurrence only of the exact unigrams: `caused', `causing', or `causes'. The word `cause' was not included due to its use as a popular contraction for `because'. One `cause-word' per document restricted the analysis to single relationships between two relata. Documents that contain bidirectional words (`associate', `relate', `connect', `correlate', and any of their stems) were also not selected for analysis. This is because our focus is on causality, an inherently one-sided relationship between two objects. We also did not consider additional synonyms of these cause words, although that could be pursued for future work. Control documents were also selected. These documents did not contain any of `caused', `causing', or `causes', nor any bidirectional words, and are further matched temporally to obtain the same number of control documents as causal documents in each fifteen-minute period during 2013. Control documents were otherwise selected randomly; causal synonyms may be present. The end result of this procedure identified 965,560 causal and 965,560 control documents.

        "question": "How do Nietzsche and Haraway critique the concept of scientific knowledge and its pursuit of objectivity? How do they use the ideas of \"the god-trick\" and \"pride\" to explain the faults in scientific discoveries?",
        "evidence": "",
        "answer": "In Nietzsche’s, “On the Truth and Lies in a Nonmoral Sense” Nietzsche explains his attitude towards human scientific knowledge with great skepticism, even alluding to humans as “the most arrogant and mendacious” creations (On Truth and Lying in an Extra-Moral Sense, 7). This same sort of criticism is brought up in the concept of “the god-trick” in Haraway’s, “Situated Knowledge: The Science Question in Feminism and the Privilege of Partial Perspective.” Haraway explains this concept as an illusion within which humans compare their own knowledge to the idea of infinite knowledge to that of a god. This sort of intellectual superiority has been a long-standing concept in human history as we have progressed in scientific thought. Described initially in Haraway’s writing, “the god-trick” remerges in many ideas Nietzsche exemplifies this through various metaphors and explanations of biases through perceptions.\nThis idea of the “the god-trick” and its qualities of knowing all, stem from humans and their rigid minds, being able to grasp only at what is tangible in their own minds, consequently shutting out other perspectives. Humans approach scientific discovery with a biased view, through their own one-sided viewpoint, and through no fault of their own make scientific discoveries which come from their own observations. But it isn't at this point where human faults are exemplified, Nietzsche argues, rather when scientific discovery is built upon these so-called\n “scientific truths.” It is at this point in time where in a moment notice the concept of science could “swell up like a balloon at the slightest puff” because of the very construct of scientific advancement based on falsities (On Truth and Lying in an Extra-Moral Sense, 7). Yet, given the knowledge of how fallible so many human discoveries have the potential to be, we still hold on to the idea of superior credibility which can be challenged by no force in our world, in essence, what Haraway refers to. In her idea of the “the god-trick,” Haraway advocates for a different way we approach observations through a different approach to objectivity. In separating ourselves from the almost seemingly personal obligation of being able to understand anything and everything and accepting the complexities of science we are able to remove the idea of false compromise on scientific truths to make up for our lack of understanding.\nA fundamental idea that is exemplified in Nietzsche’s writing, is the idea of pride. Pride is a large component of human behavior and many actions are justified. The concept of pride can even be seen as an answer to the implied questions of where the root of the “god-trick” is derived from. From the beginning of time, it can be observed that we humans have had an itch for the idea of conquering. An itch to conquer societies, cultures, land, or even something as simple as higher socioeconomic status. It's quite simply in our blood and has been present for generations of humans. Furthering Haraway’s argument, Nietzsche presents the idea of how being prideful in the depth of our “knowledgeable” we are “blinding fog over the eyes and senses of men'' exemplifying how pride can produce scientific thought that provides answers just for the sake of answering questions that in reality are faulty (On Truth and Lying in an Extra-Moral Sense, 7). As a result of this, a curtain of deception is created in which humans have assisted in the creation\n\nof their lies which to them have been converted into truth. Scientific discovery from this point on leads to “truth” being built upon from lies.\nTurning a blind eye is a large theme within the idea of “the god-trick” and is iterated upon in Nietzsche’s description of the “leaf.” The leaf is a broad example of this created by “disregarding... differences and forgetting distinguishing aspects” (On Truth and Lying in an Extra-Moral Sense, 24). What is described here is that humans cannot label an \"essential quality\" for anything they describe. In essence, it is understood that there are many different types of leaves but we are not able to explain the explicit differences among them and in doing so what arises is a lack of “truth'' with the leaf. The fault lies in the generalization of the leaf and applying this generalization to other contexts is where the fault lies, which is exactly what Haraway addresses in her “god-trick” illusion. The very definition of “the god-trick” includes generalizing our own knowledge to compensate for the holes in our discovery and knowledge.\nThrough years of scientific advancement and gain in understanding our world, the so-called truths that humans have established may have faults resulting from the way the scientific method approaches them. Haraway suggests that our way of utilizing objectivity needs to reworked to be more inclusive and Nietzsche’s writings extend upon this idea and exemplify how these truths may have fault in them as a result of assumptions. These assumptions built on top of each other lead to the lack of understanding that both authors argue.",

        "evidence": "The proliferation of the online social media has lately resulted in the democratization of online content sharing. Among other media, Twitter is very popular for research and application purposes due to its scale, representativeness and ease of public access to its content. However, tweets, that are short messages of up to 140 characters, pose several challenges to traditional Natural Language Processing (NLP) systems due to the creative use of characters and punctuation symbols, abbreviations ans slung language.\nNamed Entity Recognition (NER) is a fundamental step for most of the information extraction pipelines. Importantly, the terse and difficult text style of tweets presents serious challenges to NER systems, which are usually trained using more formal text sources such as newswire articles or Wikipedia entries that follow particular morpho-syntactic rules. As a result, off-the-self tools trained on such data perform poorly BIBREF0 . The problem becomes more intense as the number of entities to be identified increases, moving from the traditional setting of very few entities (persons, organization, time, location) to problems with more. Furthermore, most of the resources (e.g., software tools) and benchmarks for NER are for text written in English. As the multilingual content online increases, and English may not be anymore the lingua franca of the Web. Therefore, having resources and benchmarks in other languages is crucial for enabling information access worldwide.\nIn this paper, we propose a new benchmark for the problem of NER for tweets written in French. The tweets were collected using the publicly available Twitter API and annotated with 13 types of entities. The annotators were native speakers of French and had previous experience in the task of NER. Overall, the generated datasets consists of INLINEFORM0 tweets, split in training and test parts.\nThe paper is organized in two parts. In the first, we discuss the data preparation steps (collection, annotation) and we describe the proposed dataset. The dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated. Following, the second part of the paper presents an overview of baseline systems and the approaches employed by the systems that participated. We conclude with a discussion of the performance of Twitter NER systems and remarks for future work.\nThe annotators were native speakers of French and had previous experience in the task of NER.",

        "answer": "The variation of sentiment expressed in tweets from different locations (within the USA), times of day, days of the week, months and authors.",
        "evidence": "Twitter is a micro-blogging platform and a social network where users can publish and exchange short messages of up to 140 characters long (also known as tweets). Twitter has seen a great rise in popularity in recent years because of its availability and ease-of-use. This rise in popularity and the public nature of Twitter (less than 10% of Twitter accounts are private BIBREF0 ) have made it an important tool for studying the behaviour and attitude of people.\nOne area of research that has attracted great attention in the last few years is that of tweet sentiment classification. Through sentiment classification and analysis, one can get a picture of people's attitudes about particular topics on Twitter. This can be used for measuring people's attitudes towards brands, political candidates, and social issues.\nThere have been several works that do sentiment classification on Twitter using standard sentiment classification techniques, with variations of n-gram and bag of words being the most common. There have been attempts at using more advanced syntactic features as is done in sentiment classification for other domains BIBREF1 , BIBREF2 , however the 140 character limit imposed on tweets makes this hard to do as each article in the Twitter training set consists of sentences of no more than several words, many of them with irregular form BIBREF3 .\nOn the other hand, what tweets lack in structure they make up with sheer volume and rich metadata. This metadata includes geolocation, temporal and author information. We hypothesize that sentiment is dependent on all these contextual factors. Different locations, times and authors have different emotional valences. For instance, people are generally happier on weekends and certain hours of the day, more depressed at the end of summer holidays, and happier in certain states in the United States. Moreover, people have different baseline emotional valences from one another. These claims are supported for example by the annual Gallup poll that ranks states from most happy to least happy BIBREF4 , or the work by Csikszentmihalyi and Hunter BIBREF5 that showed reported happiness varies significantly by day of week and time of day. We believe these factors manifest themselves in sentiments expressed in tweets and that by accounting for these factors, we can improve sentiment classification on Twitter.\nIn this work, we explored this hypothesis by utilizing distant supervision BIBREF6 to collect millions of labelled tweets from different locations (within the USA), times of day, days of the week, months and authors. We used this data to analyse the variation of tweet sentiments across the aforementioned categories. We then used a Bayesian approach to incorporate the relationship between these factors and tweet sentiments into standard n-gram based Twitter sentiment classification.\nThis paper is structured as follows. In the next sections we will review related work on sentiment classification, followed by a detailed explanation of our approach and our data collection, annotation and processing efforts. After that, we describe our baseline n-gram sentiment classifier model, followed by the explanation of how the baseline model is extended to incorporate contextual information. Next, we describe our analysis of the variation of sentiment within each of the contextual categories. We then evaluate our models and finally summarize our findings and contributions and discuss possible paths for future work.\nIn this work, we explored this hypothesis by utilizing distant supervision to collect millions of labelled tweets from different locations (within the USA), times of day, days of the week, months and authors.

Full syntactic trees can be converted into such shallow syntactic chunk sequences using a deterministic procedure BIBREF9. BIBREF12 offered a rule-based transformation deriving non-overlapping chunks from phrase-structure trees as found in the Penn Treebank BIBREF13. The procedure percolates some syntactic phrase nodes from a phrase-syntactic tree to the phrase in the leaves of the tree. All overlapping embedded phrases are then removed, and the remainder of the phrase gets the percolated label—this usually corresponds to the head word of the phrase.\nIn order to obtain shallow syntactic annotations on a large corpus, we train a BiLSTM-CRF model BIBREF14, BIBREF15, which achieves 97% $F_1$ on the CoNLL 2000 benchmark test set.

        "evidence": "For the implementation of our neural network, we used pytorch-pretrained-bert library containing the pre-trained BERT model, text tokenizer, and pre-trained WordPiece. As the implementation environment, we use Google Colaboratory tool which is a free research tool with a Tesla K80 GPU and 12G RAM. Based on our experiments, we trained our classifier with a batch size of 32 for 3 epochs. The dropout probability is set to 0.1 for all layers. Adam optimizer is used with a learning rate of 2e-5. As an input, we tokenized each tweet with the BERT tokenizer. It contains invalid characters removal, punctuation splitting, and lowercasing the words. Based on the original BERT BIBREF11, we split words to subword units using WordPiece tokenization. As tweets are short texts, we set the maximum sequence length to 64 and in any shorter or longer length case it will be padded with zero values or truncated to the maximum length.\nWe consider 80% of each dataset as training data to update the weights in the fine-tuning phase, 10% as validation data to measure the out-of-sample performance of the model during training, and 10% as test data to measure the out-of-sample performance after training. To prevent overfitting, we use stratified sampling to select 0.8, 0.1, and 0.1 portions of tweets from each class (racism/sexism/neither or hate/offensive/neither) for train, validation, and test. Classes' distribution of train, validation, and test datasets are shown in Table TABREF16.\nAs it is understandable from Tables TABREF16(classdistributionwaseem) and TABREF16(classdistributiondavidson), we are dealing with imbalance datasets with various classes’ distribution. Since hate speech and offensive languages are real phenomena, we did not perform oversampling or undersampling techniques to adjust the classes’ distribution and tried to supply the datasets as realistic as possible. We evaluate the effect of different fine-tuning strategies on the performance of our model. Table TABREF17 summarized the obtained results for fine-tuning strategies along with the official baselines. We use Waseem and Hovy BIBREF5, Davidson et al. BIBREF9, and Waseem et al. BIBREF10 as baselines and compare the results with our different fine-tuning strategies using pre-trained BERTbase model. The evaluation results are reported on the test dataset and on three different metrics: precision, recall, and weighted-average F1-score. We consider weighted-average F1-score as the most robust metric versus class imbalance, which gives insight into the performance of our proposed models. According to Table TABREF17, F1-scores of all BERT based fine-tuning strategies except BERT + nonlinear classifier on top of BERT are higher than the baselines. Using the pre-trained BERT model as initial embeddings and fine-tuning the model with a fully connected linear classifier (BERTbase) outperforms previous baselines yielding F1-score of 81% and 91% for datasets of Waseem and Davidson respectively. Inserting a CNN to pre-trained BERT model for fine-tuning on downstream task provides the best results as F1- score of 88% and 92% for datasets of Waseem and Davidson and it clearly exceeds the baselines. Intuitively, this makes sense that combining all pre-trained BERT layers with a CNN yields better results in which our model uses all the information included in different layers of pre-trained BERT during the fine-tuning phase. This information contains both syntactical and contextual features coming from lower layers to higher layers of BERT.\nAs the implementation environment, we use Google Colaboratory tool which is a free research tool with a Tesla K80 GPU and 12G RAM.",

        "evidence": "Data. We build a dataset of Twitter accounts based on two lists annotated in previous works. For the non-factual accounts, we rely on a list of 180 Twitter accounts from BIBREF1. This list was created based on public resources where suspicious Twitter accounts were annotated with the main fake news types (clickbait, propaganda, satire, and hoax). We discard the satire labeled accounts since their intention is not to mislead or deceive. On the other hand, for the factual accounts, we use a list with another 32 Twitter accounts from BIBREF19 that are considered trustworthy by independent third parties. We discard some accounts that publish news in languages other than English (e.g., Russian or Arabic). Moreover, to ensure the quality of the data, we remove the duplicate, media-based, and link-only tweets. For each account, we collect the maximum amount of tweets allowed by Twitter API. Table TABREF13 presents statistics on our dataset.\n\nBaselines. We compare our approach (FacTweet) to the following set of baselines:\n[leftmargin=4mm]\nLR + Bag-of-words: We aggregate the tweets of a feed and we use a bag-of-words representation with a logistic regression (LR) classifier.\nTweet2vec: We use the Bidirectional Gated recurrent neural network model proposed in BIBREF20. We keep the default parameters that were provided with the implementation. To represent the tweets, we use the decoded embedding produced by the model. With this baseline we aim at assessing if the tweets' hashtags may help detecting the non-factual accounts.\nLR + All Features (tweet-level): We extract all our features from each tweet and feed them into a LR classifier. Here, we do not aggregate over tweets and thus view each tweet independently.\nLR + All Features (chunk-level): We concatenate the features' vectors of the tweets in a chunk and feed them into a LR classifier.\nFacTweet (tweet-level): Similar to the FacTweet approach, but at tweet-level; the sequential flow of the tweets is not utilized. We aim at investigating the importance of the sequential flow of tweets.\nTop-$k$ replies, likes, or re-tweets: Some approaches in rumors detection use the number of replies, likes, and re-tweets to detect rumors BIBREF21. Thus, we extract top $k$ replied, liked or re-tweeted tweets from each account to assess the accounts factuality. We tested different $k$ values between 10 tweets to the max number of tweets from each account. Figure FIGREF24 shows the macro-F1 values for different $k$ values. It seems that $k=500$ for the top replied tweets achieves the highest result. Therefore, we consider this as a baseline.\n\nExperimental Setup. We apply a 5 cross-validation on the account's level. For the FacTweet model, we experiment with 25% of the accounts for validation and parameters selection. We use hyperopt library to select the hyper-parameters on the following values: LSTM layer size (16, 32, 64), dropout ($0.0-0.9$), activation function ($relu$, $selu$, $tanh$), optimizer ($sgd$, $adam$, $rmsprop$) with varying the value of the learning rate (1e-1,..,-5), and batch size (4, 8, 16). The validation split is extracted on the class level using stratified sampling: we took a random 25% of the accounts from each class since the dataset is unbalanced. Discarding the classes' size in the splitting process may affect the minority classes (e.g. hoax). For the baselines' classifier, we tested many classifiers and the LR showed the best overall performance.\n\nResults. Table TABREF25 presents the results. We present the results using a chunk size of 20, which was found to be the best size on the held-out data. Figure FIGREF24 shows the results of different chunks sizes. FacTweet performs better than the proposed baselines and obtains the highest macro-F1 value of $0.565$. Our results indicate the importance of taking into account the sequence of the tweets in the accounts' timelines. The sequence of these tweets is better captured by our proposed model sequence-agnostic or non-neural classifiers. Moreover, the results demonstrate that the features at tweet-level do not perform well to detect the Twitter accounts factuality, since they obtain a result near to the majority class ($0.18$). Another finding from our experiments shows that the performance of the Tweet2vec is weak. This demonstrates that tweets' hashtags are not informative to detect non-factual accounts. In Table TABREF25, we present ablation tests so as to quantify the contribution of subset of features. The results indicate that most performance gains come from words embeddings, style, and morality features. Other features (emotion and sentiment) show lower importance: nevertheless, they still improve the overall system performance (on average 0.35% Macro-F$_1$ improvement). These performance figures suggest that non-factual accounts use semantic and stylistic hidden signatures mostly while tweeting news, so as to be able to mislead the readers and behave as reputable (i.e., factual) sources. We leave a more fine-grained, diachronic analysis of semantic and stylistic features – how semantic and stylistic signature evolve across time and change across the accounts' timelines – for future work.\nThese performance figures suggest that non-factual accounts use semantic and stylistic hidden signatures mostly while tweeting news, so as to be able to mislead the readers and behave as reputable (i.e., factual) sources.",

Jiang was paramount leader of China from 1989 to 2002. He was the core leader of the third generation of Chinese leadership, one of four core leaders alongside Mao Zedong, Deng Xiaoping and Xi Jinping.\n\nBorn in Yangzhou, Jiangsu, Jiang joined the CCP while he was in college. After the establishment of the People's Republic of China in 1949, he received training at the Stalin Automobile Works in Moscow in the 1950s, later returning to Shanghai in 1962 to serve in various institutes, later being sent between 1970-1972 to Romania as part of an expert team to establish machinery manufacturing plants in the country. After 1979, he was appointed as the vice chair of two commissions by vice premier Gu Mu to oversee the newly-established special economic zones (SEZs). He became the vice minister of the newly-established Ministry of Electronics Industry and a member of the CCP Central Committee in 1982.\n\nJiang was appointed as the mayor of Shanghai in 1985, later being promoted to its Communist Party secretary, as well as a member of the CCP Politburo, in 1987. Jiang came to power unexpectedly as a compromise candidate following the 1989 Tiananmen Square protests and massacre, when he replaced Zhao Ziyang as CCP general secretary after Zhao was ousted for his support for the student movement. As the involvement of the \"Eight Elders\" in Chinese politics steadily declined, Jiang consolidated his hold on power to become the \"paramount leader\" in the country during the 1990s. Urged by Deng Xiaoping's southern tour in 1992, Jiang officially introduced the term \"socialist market economy\" in his speech during the 14th CCP National Congress held later that year, which accelerated \"opening up and reform\".\n\nUnder Jiang's leadership, China experienced substantial economic growth with the continuation of market reforms. The returning of Hong Kong from the United Kingdom in 1997 and of Macau from Portugal in 1999, and entry into the World Trade Organisation in 2001, were landmark moments of his era. China also witnessed improved relations with the outside world, while the Communist Party maintained its tight control over the state. Jiang faced criticism over human rights abuses, including the crackdown on the Falun Gong movement. His contributions to party doctrine, known as the \"Three Represents\", were written into the CCP constitution in 2002. Jiang gradually vacated his official leadership titles from 2002 to 2005, being succeeded in these roles by Hu Jintao, although he and his political faction continued to influence affairs until much later.

They don't even understand people, yet they think they can predict the behavior of new, self-guiding AI?” –anonymous\n“I think an AI would make it easier for Patients to confide their information because by nature, a robot cannot judge them. Win-win? :D”' –anonymous\nDogmatism describes the tendency to lay down opinions as incontrovertibly true, without respect for conflicting evidence or the opinions of others BIBREF0 . Which user is more dogmatic in the examples above? This question is simple for humans. Phrases like “they think” and “they don't even understand,” suggest an intractability of opinion, while “I think” and “win-win?” suggest the opposite. Can we train computers to draw similar distinctions? Work in psychology has called out many aspects of dogmatism that can be modeled computationally via natural language, such as over-confidence and strong emotions BIBREF1 .\nWe present a statistical model of dogmatism that addresses two complementary goals. First, we validate psychological theories by examining the predictive power of feature sets that guide the model's predictions. For example, do linguistic signals of certainty help to predict a post is dogmatic, as theory would suggest? Second, we apply our model to answer four questions:\nR1: What kinds of topics (e.g., guns, LGBT) attract the highest levels of dogmatism?\nR2: How do dogmatic beliefs cluster?\nR3: How does dogmatism influence a conversation on social media? R4: How do other user behaviors (e.g., frequency and breadth of posts) relate to dogmatism?\nWe train a predictive model to classify dogmatic posts from Reddit, one of the most popular discussion communities on the web. Posts on Reddit capture discussion and debate across a diverse set of domains and topics – users talk about everything from climate change and abortion, to world news and relationship advice, to the future of artificial intelligence. As a prerequisite to training our model, we have created a corpus of 5,000 Reddit posts annotated with levels of dogmatism, which we are releasing to share with other researchers.\nUsing the model, we operationalize key domain-independent aspects of psychological theories of dogmatism drawn from the literature. We find these features have predictive power that largely supports the underlying theory. For example, posts that use less confident language tend to be less dogmatic. We also discover evidence for new attributes of dogmatism. For example, dogmatic posts tend not to verbalize cognition, through terms such as “I think,” “possibly,” or “might be.”\nOur model is trained on only 5,000 annotated posts, but once trained, we use it to analyze millions of other Reddit posts to answer our research questions. We find a diverse set of topics are colored by dogmatic language (e.g., people are dogmatic about religion, but also about LGBT issues). Further, we find some evidence for dogmatism as a deeper personality trait – people who are strongly dogmatic about one topic are more likely to express dogmatic views about others as well. Finally, in conversation, we discover that one user's dogmatism tends to bring out dogmatism in their conversational partner, forming a vicious cycle.\nPosts on Reddit capture debate and discussion across a diverse set of topics, making them a natural starting point for untangling domain-independent linguistic features of dogmatism.\nData collection. Subreddits are sub-communities on Reddit oriented around specific interests or topics, such as technology or politics. Sampling from Reddit as a whole would bias the model towards the most commonly discussed content. But by sampling posts from individual subreddits, we can control the kinds of posts we use to train our model. To collect a diverse training dataset, we have randomly sampled 1000 posts each from the subreddits politics, business, science, and AskReddit, and 1000 additional posts from the Reddit frontpage. All posts in our sample appeared between January 2007 and March 2015, and to control for length effects, contain between 300 and 400 characters. This results in a total training dataset of 5000 posts.\nDogmatism annotations. Building a useful computational model requires labeled training data. We labeled the Reddit dataset using crowdworkers on Amazon Mechanical Turk (AMT), creating the first public corpus annotated with levels of dogmatism. We asked crowdworkers to rate levels of dogmatism on a 5-point Likert scale, as supported by similar annotation tasks in prior work BIBREF2 . Concretely, we gave crowdworkers the following task: \nGiven a comment, imagine you hold a well-informed, different opinion from the commenter in question. We'd like you to tell us how likely that commenter would be to engage you in a constructive conversation about your disagreement, where you each are able to explore the other's beliefs. The options are:\n(5): It's unlikely you'll be able to engage in any substantive conversation. When you respectfully express your disagreement, they are likely to ignore you or insult you or otherwise lower the level of discourse.\n(4): They are deeply rooted in their opinion, but you are able to exchange your views without the conversation degenerating too much.\n(3): It's not likely you'll be able to change their mind, but you're easily able to talk and understand each other's point of view.\n(2): They may have a clear opinion about the subject, but would likely be open to discussing alternative viewpoints.\n(1): They are not set in their opinion, and it's possible you might change their mind. If the comment does not convey an opinion of any kind, you may also select this option.\nTo ensure quality work, we restricted the task to Masters workers and provided examples corresponding to each point on the scale. Including examples in a task has been shown to significantly increase the agreement and quality of crowdwork BIBREF3 .

To evaluate the reliability of annotations we compute Krippendorff's $\\alpha $ , a measure of agreement designed for variable levels of measurement such as a Likert scale BIBREF5 . An $\\alpha $ of 0 indicates agreement indistinguishable from chance, while an $\\alpha $ of 1 indicates perfect agreement. Across all annotations we find $\\alpha =0.44$ . While workers agree much more than chance, clearly dogmatism is also subjective. In fact, when we examine only the middle two quartiles of the dogmatism annotations, we find agreement is no better than chance. Alternatively, when we measure agreement only among the top and bottom quartiles of annotations, we find agreement of $\\alpha =0.69$ . This suggests comments with scores that are only slightly dogmatic are unreliable and often subject to human disagreement.

The significance of the correlation is tested by chi-square independence with p value less than 0.05. Identifying these patterns will enable interventions to be differentiated for and targeted at specific populations. For instance, the young harassers often engage in harassment activities as groups. This points to the influence of peer pressure and masculine behavioral norms for men and boys on these activities.

        "answer": "Character-level models.",
        "evidence": "Encoding of words is perhaps the most important step towards a successful end-to-end natural language processing application. Although word embeddings have been shown to provide benefit to such models, they commonly treat words as the smallest meaning bearing unit and assume that each word type has its own vector representation. This assumption has two major shortcomings especially for languages with rich morphology: (1) inability to handle unseen or out-of-vocabulary (OOV) word-forms (2) inability to exploit the regularities among word parts. The limitations of word embeddings are particularly pronounced in sentence-level semantic tasks, especially in languages where word parts play a crucial role. Consider the Turkish sentences “Köy+lü-ler (villagers) şehr+e (to town) geldi (came)” and “Sendika+lı-lar (union members) meclis+e (to council) geldi (came)”. Here the stems köy (village) and sendika (union) function similarly in semantic terms with respect to the verb come (as the origin of the agents of the verb), where şehir (town) and meclis (council) both function as the end point. These semantic similarities are determined by the common word parts shown in bold. However ortographic similarity does not always correspond to semantic similarity. For instance the ortographically similar words knight and night have large semantic differences. Therefore, for a successful semantic application, the model should be able to capture both the regularities, i.e, morphological tags and the irregularities, i.e, lemmas of the word.\nMorphological analysis already provides the aforementioned information about the words. However access to useful morphological features may be problematic due to software licensing issues, lack of robust morphological analyzers and high ambiguity among analyses. Character-level models (CLM), being a cheaper and accessible alternative to morphology, have been reported as performing competitively on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 . However the extent to which these tasks depend on morphology is small; and their relation to semantics is weak. Hence, little is known on their true ability to reveal the underlying morphological structure of a word and their semantic capabilities. Furthermore, their behaviour across languages from different families; and their limitations and strengths such as handling of long-range dependencies, reaction to model complexity or performance on out-of-domain data are unknown. Analyzing such issues is a key to fully understanding the character-level models.\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:\n $[$ Villagers $]$ comers came $[$ to town $]$ end point\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis. The gold morphology serves as the upper bound for us to compare and analyze the performances of character-level models on languages of varying morphological typologies. We carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology. In regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English. Our experiments and analysis reveal insights such as:\nIn regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.",

It aims at comparing a pair of sentences (i.e. a premise and a hypothesis), and inferring the relationship between them (i.e., entailment, neutral and contradiction). Large-scaled datasets like SNLI BIBREF0 and MultiNLI BIBREF1 have been created by crowd-sourcing and fertilized NLI research substantially.\nHowever, several works BIBREF2, BIBREF3, BIBREF4 have pointed out that crowd-sourcing workers have brought a bias pattern named annotation artifacts in these NLI datasets. Such artifacts in hypotheses can reveal the labels and make it possible to predict the labels solely by looking at the hypotheses. For example, models trained on SNLI with only the hypotheses can achieve an accuracy of 67.0%, despite the always predicting the majority-class baseline is only 34.3% BIBREF2.\nClassifiers trained on NLI datasets are supposed to make predictions by understanding the semantic relationships between given sentence pairs. However, it is shown that models are unintentionally utilizing the annotation artifacts BIBREF4, BIBREF2. If the evaluation is conducted under a similar distribution as the training data, e.g., with the given testing set, models will enjoy additional advantages, making the evaluation results over-estimated. On the other hand, if the bias pattern cannot be generalized to the real-world, it may introduce noise to models, thus hurting the generalization ability.\nIn this paper, we use cross-dataset testing to better assess models' generalization ability. We investigate the impacts of annotation artifacts in cross-dataset testing. Furthermore, we propose an easy-adopting debiasing training framework, which doesn't require any additional data or annotations, and apply it to the high-performing Densely Interactive Inference Network BIBREF5. Experiments show that our method can effectively mitigate the bias pattern and improve the cross-dataset generalization ability of models.

        "evidence": "Natural language generation (NLG) has been one of the key topics of research in natural language processing, which was highlighted by the huge body of work on NLG surveyed in BIBREF0, BIBREF1. With the advances of several devices capable of understanding spoken language and conducting conversation with human (e.g., Google Home, Amazon Echo) and the shrinking gap created by the digital devices, it is not difficult to foresee that the market and application areas of NLG systems will continue to grow, especially in applications whose users are non-experts. In such application, a user often asks for certain information and waits for the answer and a NLG module would return the answer in spoken language instead of text such as in question-answering systems or recommendation systems. The NLG system in these two applications uses templates to generate the answers in natural language for the users. A more advanced NLG system in this direction is described in BIBREF2, which works with ontologies annotated using the Attempto language and can generate a natural language description for workflows created by the systems built in the Phylotastic project. The applications targeted by these systems are significantly different from NLG systems, whose main purpose is to generate high-quality natural language description of objects or reports, such as those reported in the recent AAAI conference BIBREF3, BIBREF4, BIBREF5.\nThe present paper is motivated by the need to generate natural language description of computational results to non-expert users such as those developed in the Phylotastic project. In this project, the users are experts in evolutionary biology but are none experts in ontologies and web services. When a user places a request, he/she will receive a workflow consisting of web services, whose inputs and outputs are specified by instances of classes in the ontologies working with web services, as well as the ordering and relationships between the services. To assist the user in understanding the workflow, a natural language description of the workflow is generated. In order to accomplish the task, the NLG system in the Phylotastic project proposes to annotate elements of the ontologies using Attempto, a simple subset of English with precisely defined syntax and semantics.\nIn this paper, we propose a system that addresses the limitation of the system discussed in the Phylotastic project BIBREF2. Specifically, we assume that the annotations given in an ontology are natural language sentences. This is a reasonable assumption given that the developers of an ontology are usually those who have intimate knowledge about entities described in the ontology and often have some sort of comments about classes, objects, and instances of the ontology. We then show that the system is very flexible and can be used for the same purpose with new ontologies.\nThe rest of the paper is organized as follows. Section SECREF2 briefly reviews the basics of Grammatical Framework (GF)BIBREF6. Section SECREF3 describes the main modules of the system.

We outline that $J_i$ might differ between entities.\n$\\bullet $ A data-structure $s$ is an unordered set of $I$ entities $e_i$. We thus denote $s \\lbrace e_1, ..., e_i, ..., e_I\\rbrace $.\n$\\bullet $ For each data-structure, a textual description $y$ is associated. We refer to the first $t$ words of a description $y$ as $y_{1:t}$. Thus, the full sequence of words can be noted as $y = y_{1:T}$.\n$\\bullet $ The dataset $\\mathcal {D}$ is a collection of $N$ aligned (data-structure, description) pairs $(s,y)$.\nFor instance, Figure FIGREF1 illustrates a data-structure associated with a description. The data-structure includes a set of entities (Hawks, Magic, Al Horford, Jeff Teague, ...). The entity Jeff Teague is modeled as a set of records {(PTS, 17), (REB, 0), (AST, 7) ...} in which, e.g., the record (PTS, 17) is characterized by a key (PTS) and a value (17).\nFor each data-structure $s$ in $\\mathcal {D}$, the objective function aims to generate a description $\\hat{y}$ as close as possible to the ground truth $y$. This objective function optimizes the following log-likelihood over the whole dataset $\\mathcal {D}$:\nwhere $\\theta $ stands for the model parameters and $P(\\hat{y}=y\\ |\\ s; \\theta )$ the probability of the model to generate the adequate description $y$ for table $s$.\nDuring inference, we generate the sequence $\\hat{y}^*$ with the maximum a posteriori probability conditioned on table $s$.

        "question": "What are the main categories of existing methods for zero-shot translation in NMT?",
        "answer": "Pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.",
        "evidence": "In recent years, zero-shot translation in NMT has attracted widespread attention in academic research. Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.\nPivot-based Method is a common strategy to obtain a source$\\rightarrow $target model by introducing a pivot language. This approach is further divided into pivoting and pivot-synthetic. While the former firstly translates a source language into the pivot language which is later translated to the target language BIBREF4, BIBREF5, BIBREF12, the latter trains a source$\\rightarrow $target model with pseudo data generated from source-pivot or pivot-target parallel data BIBREF13, BIBREF14. Although the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter-vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation problem BIBREF15.\nTransfer Learning is firstly introduced for NMT by BIBREF6, which leverages a high-resource parent model to initialize the low-resource child model. On this basis, BIBREF7 and BIBREF8 use shared vocabularies for source/target language to improve transfer learning, while BIBREF16 relieve the vocabulary mismatch by mainly using cross-lingual word embedding. Although these methods are successful in the low-resource scene, they have limited effects in zero-shot translation.\nMultilingual NMT (MNMT) enables training a single model that supports translation from multiple source languages into multiple target languages, even those unseen language pairs BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21. Aside from simpler deployment, MNMT benefits from transfer learning where low-resource language pairs are trained together with high-resource ones. However, BIBREF22 point out that MNMT for zero-shot translation easily fails, and is sensitive to the hyper-parameter setting. Also, MNMT usually performs worse than the pivot-based method in zero-shot translation setting BIBREF23.\nUnsupervised NMT (UNMT) considers a harder setting, in which only large-scale monolingual corpora are available for training. Recently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training BIBREF24, BIBREF25, BIBREF26, BIBREF11. Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.\nOur proposed method belongs to the transfer learning, but it is different from traditional transfer methods which train a parent model as starting point. Before training a parent model, our approach fully leverages cross-lingual pre-training methods to make all source languages share the same feature space and thus enables a smooth transition for zero-shot translation.\nIn recent years, zero-shot translation in NMT has attracted widespread attention in academic research.  Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.",

        "question": "In Record Embedding Layer, what does the low-level encoder aim at?",
        "answer": "Encoding a collection of records belonging to the same entity.",
        "evidence": "As outlined in Section SECREF2, most previous work BIBREF28, BIBREF12, BIBREF13, BIBREF10, BIBREF29 make use of flat encoders that do not exploit the data structure. To keep the semantics of each element from the data-structure, we propose a hierarchical encoder which relies on two modules. The first one (module A in Figure FIGREF11) is called low-level encoder and encodes entities on the basis of their records; the second one (module B), called high-level encoder, encodes the data-structure on the basis of its underlying entities. In the low-level encoder, the traditional embedding layer is replaced by a record embedding layer as in BIBREF11, BIBREF12, BIBREF10. We present in what follows the record embedding layer and introduce our two hierarchical modules.\nThe first layer of the network consists in learning two embedding matrices to embed the record keys and values. Keys $k_{i,j}$ are embedded to $\\mathbf {k}_{i,j} \\in \\mathbb {R}^{d}$ and values $v_{i,j}$ to $\\mathbf {v}_{i,j} \\in \\mathbb {R}^{d}$, with $d$ the size of the embedding. As in previous work BIBREF11, BIBREF12, BIBREF10, each record embedding $\\mathbf {r}_{i,j}$ is computed by a linear projection on the concatenation $[\\mathbf {k}_{i,j}$; $\\mathbf {v}_{i,j}]$ followed by a non linearity:\nwhere $\\mathbf {W}_r \\in \\mathbb {R}^{2d \\times d}$ and $\\mathbf {b}_r \\in \\mathbb {R}^{d}$ are learnt parameters.\nThe low-level encoder aims at encoding a collection of records belonging to the same entity while the high-level encoder encodes the whole set of entities. Both the low-level and high-level encoders consider their input elements as unordered. We use the Transformer architecture from BIBREF21. For each encoder, we have the following peculiarities:\n\nthe Low-level encoder encodes each entity $e_i$ on the basis of its record embeddings $\\mathbf {r}_{i,j}$. Each record embedding $\\mathbf {r}_{i,j}$ is compared to other record embeddings to learn its final hidden representation $\\mathbf {h}_{i,j}$. Furthermore, we add a special record [ENT] for each entity, illustrated in Figure FIGREF11 as the last record. Since entities might have a variable number of records, this token allows to aggregate final hidden record representations $\\lbrace \\mathbf {h}_{i,j}\\rbrace _{j=1}^{J_i}$ in a fixed-sized representation vector $\\mathbf {h}_{i}$.\nthe High-level encoder encodes the data-structure on the basis of its entity representation $\\mathbf {h}_{i}$. Similarly to the Low-level encoder, the final hidden state $\\mathbf {e_i}$ of an entity is computed by comparing entity representation $\\mathbf {h}_{i}$ with each others. The data-structure representation $\\mathbf {z}$ is computed as the mean of these entity representations, and is used for the decoder initialization.\nThe low-level encoder aims at encoding a collection of records belonging to the same entity while the high-level encoder encodes the whole set of entities.",

        "question": "What kind of framework do they propose?",
        "answer": "A novel prototype-to-style (PS) framework that tackles the challenge of stylistic dialogue generation by leveraging useful information contained in the retrieved responses.",
        "evidence": "Most early research on dialogue response generation focused on generating grammatical and contextually relevant responses BIBREF0, BIBREF1, BIBREF2. While promising results have been demonstrated BIBREF3, BIBREF4, syntactically coherent responses alone do not guarantee an engaging and attractive dialogue system. Expressing a unique and consistent speaking style has been shown to be crucial for increasing the user's engagement with dialogue systems BIBREF5. There are various definitions of language style BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10. In this work, from a purely computational standpoint, we refer to language style as any characteristic style of expression. Hence, our work is in line with previous work on dialogue generation with emotion BIBREF11, BIBREF12, BIBREF13, BIBREF14; response attitude BIBREF15, and speaker personality BIBREF16.\nThe aforementioned approaches explicitly incorporate the language style information into the model configuration either via embeddings or memory modules to control the process of response generation. In our replication experiments, we found that these approaches tend to overemphasise the importance of the language style. As a result, the generated responses tend to be generic and non-informative BIBREF17, but they do express a distinct style; e.g., they generate a generic response: “I am happy to hear that.\" that conveys a `happy' emotion to different queries.\nIn this work, we propose a novel prototype-to-style (PS) framework to tackle the challenge of stylistic dialogue generation. Our motivation is two-fold: (1) Human-written responses are informative and diverse, which could be leveraged as guidance for the generation model; (2) However, the retrieved response is not guaranteed to express the desired language style. Moreover, the quality of the retrieved response varies among different queries due to the instability of the IR system. Therefore, to transform the retrieved result into a relevant and stylistic response, an adequate editing process is necessary.\nAn illustration of the proposed framework is shown in Figure FIGREF2, where a prototype is first extracted from the retrieved response. The stylistic response generator then takes the desired language style and the extracted prototype as additional input to obtain an adequate and stylistic response. The proposed stylistic response generator mainly inherits from the GPT-2 model BIBREF18 which is pre-trained with a large unlabeled text corpus. However, the GPT-2 model does not naturally fit the task of dialogue generation. To this end, we design various adaptations to the model architecture to extend the GPT-2 model to address the task of dialogue generation. Furthermore, in order to control the style of the generated responses, we train the model with a novel style-aware maximum likelihood estimation (MLE) objective that encodes additional style knowledge into the model's parameters. Finally, to mitigate the possible effect that the retrieved response containing irrelevant and inappropriate information with respect to the input query, we adopt a de-noising learning strategy BIBREF19, BIBREF20 to prevent the model from uncritically copying the prototype.\nTo fully evaluate the proposed approach, we conduct extensive experiments on three benchmark datasets. Results of both human and automatic evaluation show that the proposed approach significantly outperforms several strong baselines. In addition, we also conduct an extensive cross-domain experiment to demonstrate that the proposed approach is more robust than such baselines.\nIt should be noted that stylistic dialogue generation is different from the task of text style transfer. Text style transfer aims to rewrite the input sentences such that they possess certain language styles, while rigorously preserving their semantic meaning BIBREF21. On the other hand, stylistic dialogue generation does not aim at preserving the semantic meaning of the input sentences. Instead, it aims at generating sentences that are adequate and relevant responses to the input sentences, while expressing the prespecified language styles.\nIn summary, the contributions of this work are: (1) We propose a novel framework that tackles the challenge of stylistic dialogue generation by leveraging useful information contained in the retrieved responses; (2) We propose a new stylistic response generator by making proper adaptations to a large-scale pre-trained language model. We train our model with a new style-aware learning objective in a de-noising manner. Experiments show that the proposed model outperforms many strong baselines on three benchmark datasets on both in-domain and cross-domain evaluations.\nIn this work, we propose a novel prototype-to-style (PS) framework to tackle the challenge of stylistic dialogue generation.",

The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.\n\nWorld War II was by far the deadliest conflict in history; it resulted in an estimated 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massacres, and disease. In the wake of the Axis defeat, Germany and Japan were occupied, and war crimes tribunals were conducted against German and Japanese leaders.\n\nThe causes of World War II are debated, but contributing factors included the Second Italo-Ethiopian War, Spanish Civil War, Second Sino-Japanese War, Soviet–Japanese border conflicts, the rise of fascism in Europe, and European tensions in the aftermath of World War I. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland. The United Kingdom and France subsequently declared war on Germany on 3 September. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union had partitioned Poland and marked out their \"spheres of influence\" across Finland, Estonia, Latvia, Lithuania and Romania. From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, in a military alliance with Italy, Japan and other countries called the Axis. Following the onset of campaigns in North Africa and East Africa, and the fall of France in mid-1940, the war continued primarily between the European Axis powers and the British Empire, with war in the Balkans, the aerial Battle of Britain, the Blitz of the United Kingdom, and the Battle of the Atlantic.

        "question": "Given the this paragraph about the invention of transistors, why did lawyers at Bell Labs advise Shockley against filing a patent for his field-effect transistors?",
        "evidence": "From November 17 to December 23, 1947, John Bardeen and Walter Brattain at AT&T's Bell Labs in Murray Hill, New Jersey performed experiments and observed that when two gold point contacts were applied to a crystal of germanium, a signal was produced with the output power greater than the input. Solid State Physics Group leader William Shockley saw the potential in this, and over the next few months worked to greatly expand the knowledge of semiconductors. The term transistor was coined by John R. Pierce as a contraction of the term transresistance. According to Lillian Hoddeson and Vicki Daitch, Shockley proposed that Bell Labs' first patent for a transistor should be based on the field-effect and that he be named as the inventor. Having unearthed Julius Edgar Lilienfeld's patents that went into obscurity years earlier, lawyers at Bell Labs advised against Shockley's proposal because the idea of a field-effect transistor that used an electric field as a \"grid\" was not new. Instead, what Bardeen, Brattain, and Shockley invented in 1947 was the first point-contact transistor. To acknowledge this accomplishment, Shockley, Bardeen and Brattain jointly received the 1956 Nobel Prize in Physics \"for their researches on semiconductors and their discovery of the transistor effect\".",

        "evidence": "1) In classical Chinese poems, poetic images UTF8gbsn(意象) were widely used to express emotions and to build artistic conception. A certain poetic image usually has some fixed implications. For example, autumn is usually used to imply sadness and loneliness. However, with the change of time, poetic images and their implications have also changed. According to our observation, if a vernacular paragraph contains more poetic images used in classical literature, its generated poem usually achieves higher score. As illustrated in Table TABREF12, both paragraph 2 and 3 are generated from pop song lyrics, paragraph 2 uses many poetic images from classical literature (e.g. pear flowers, makeup), while paragraph 3 uses modern poetic images (e.g. sparrows on the utility pole). Obviously, compared with poem 2, sentences in poem 3 seems more confusing, as the poetic images in modern times may not fit well into the language model of classical poems.\n2) We also observed that poems generated from descriptive paragraphs achieve higher scores than from logical or philosophical paragraphs. For example, in Table TABREF12, both paragraph 4 (more descriptive) and paragraph 5 (more philosophical) were selected from famous modern prose. However, compared with poem 4, poem 5 seems semantically more confusing. We offer two explanations to the above phenomenon: i. Limited by the 28-character restriction, it is hard for quatrain poems to cover complex logical or philosophical explanation. ii. As vernacular paragraphs are more detailed and lengthy, some information in a vernacular paragraph may be lost when it is summarized into a classical poem. While losing some information may not change the general meaning of a descriptive paragraph, it could make a big difference in a logical or philosophical paragraph.\nAccording to our observation, if a vernacular paragraph contains more poetic images used in classical literature, its generated poem usually achieves higher score.\nWe also observed that poems generated from descriptive paragraphs achieve higher scores than from logical or philosophical paragraphs.",

The band consists of Thom Yorke (vocals, guitar, piano, keyboards); brothers Jonny Greenwood (lead guitar, keyboards, other instruments) and Colin Greenwood (bass); Ed O'Brien (guitar, backing vocals); and Philip Selway (drums, percussion). They have worked with the producer Nigel Godrich and the cover artist Stanley Donwood since 1994. Radiohead's experimental approach is credited with advancing the sound of alternative rock.\n\nRadiohead signed to EMI in 1991 and released their debut album, Pablo Honey, in 1993. Their debut single, \"Creep\", became a worldwide hit. Radiohead's popularity and critical standing rose with the release of The Bends in 1995. Radiohead's third album, OK Computer (1997), brought them international fame; noted for its complex production and themes of modern alienation, it is acclaimed as a landmark record and one of the best albums in popular music.\n\nRadiohead's fourth album, Kid A (2000), marked a dramatic change in style, incorporating influences from electronic music, jazz, classical music and krautrock. Though Kid A divided listeners, it was later named the best album of the decade by multiple outlets. It was followed by Amnesiac (2001), recorded in the same sessions. Hail to the Thief (2003), with lyrics addressing the War on Terror, blended the band's rock and electronic sides, and was Radiohead's final album for EMI.\n\nRadiohead self-released their seventh album, In Rainbows (2007), as a download for which customers could set their own price, to critical and chart success. Their eighth album, The King of Limbs (2011), an exploration of rhythm, was developed using extensive looping and sampling. A Moon Shaped Pool (2016) prominently featured Jonny Greenwood's orchestral arrangements. Yorke, Jonny Greenwood, Selway, and O'Brien have released solo albums; in 2021, Yorke and Jonny Greenwood debuted a new band, the Smile.\n\nBy 2011, Radiohead had sold more than 30 million albums worldwide. Their awards include six Grammy Awards and four Ivor Novello Awards, and they hold five Mercury Prize nominations, the most of any act. Seven Radiohead singles have reached the top 10 on the UK Singles Chart: \"Creep\" (1992), \"Street Spirit (Fade Out)\" (1996), \"Paranoid Android\" (1997), \"Karma Police\" (1997), \"No Surprises\" (1998), \"Pyramid Song\" (2001), and \"There There\" (2003). \"Creep\" and \"Nude\" (2008) reached the top 40 on the US Billboard Hot 100. Rolling Stone named Radiohead one of the 100 greatest artists of all time, and Rolling Stone readers voted them the second-best artist of the 2000s. Five Radiohead albums have been included in Rolling Stone's 500 Greatest Albums of All Time lists. Radiohead were inducted into the Rock and Roll Hall of Fame in 2019.",

        "answer": "(a) The main claim of this paper is to propose an RL-based strategy for improving the classification performance of an existing graph capsule neural network, namely CapsGNN, by adaptively refining the structure of the network at runtime. Specifically, we design an assistant module to continuously adjust the depth and width of graph convolutional layers over a pre-determined sliding epoch window, based on the accuracy results on the validation set and the loss reduction rate on the train set. (b) Figure 4 implies that the speedup in training brought by the parallel approach described in Section 3.3 outweighs the computational overhead introduced by the assistant module. (c) Table 2 shows that AdaGCCN outperforms CapsGNN on 6 out of 7 datasets and achieves state-of-the-art results on almost all the datasets.",
        "evidence": "Based on the neural network method, AdaGCCN takes advantage of the multi-dimension representation ability of capsules, and further explores to strengthen the information extraction ability of the model by changing depth and width of graph convolutional layers. We reproduce CapsGNN in this paper and take the test accuracies reported in other baseline works for the comparison with our\nmodel.\nIt is shown in Table 2 that our model outperforms CapsGNN on 6 out of 7 datasets by up to 6.57% on ENZYMES except for the performance on PROTEINS. Note that the graphs on PROTEINS are more complex in inner relationships, and the ∆D list and the ∆W list in current AM are manually set, thus the extraction ability of AdaGCCN would be restricted somehow. However, the main point in this paper is to propose an RL-based methodology in adaptively adjusting the model structure to improve its representation ability on various workloads, some hyper-parameters defined\nin the assistant module could be tuned to present better model performance in the future. Besides, AdaGCCN achieves state-of-the-art results almost on all datasets including biological and social graphs, which further demonstrates the effectiveness of adjusting D and W during only one full training. \nFigure 3 depicts the change of accuracies on the test fold when training with CapsGNN or AdaGCCN. Since the assistant module in AdaGCCN evaluates the loss reduction speed on the train fold and the accuracy change on the validation fold, as the training process goes on, it helps to select the ∆D and ∆W with the biggest accumulated reward. It is observed in the figure that AdaGCCN presents higher test accuracy than CapsGNN at arbitrary intermediate training stages. Besides, the\ndynamic adjustment in our model does not do any harm to its convergency compared to static CapsGNN. Note that the number of training epochs is set to be large on all datasets to ensure either CapsGNN or AdaGCCN achieves optimal classification performance during training.",

The authors of the dataset have manually annotated the relevance scores, ranging from 1 to 5, of the text-summary pairs in PART II and PART III. They suggested that only pairs with scores no less than three should be used for evaluation, which leaves 8,685 pairs in PART II, and 725 pairs in PART III.

        "evidence": "Fake News Detection Exist studies for fake news detection can be roughly summarized into two categories. The first category is to extract or construct comprehensive and complex features with manual ways BIBREF5, BIBREF8, BIBREF17. The second category is to automatically capture deep features based on neural networks. There are two ways in this category. One is to capture linguistic features from text content, such as semantic BIBREF7, BIBREF18, writing styles BIBREF4, and textual entailments BIBREF19. The other is to focus on gaining effective features from the organic integration of text and user interactions BIBREF20, BIBREF21. User interactions include users' behaviours, profiles, and networks between users. In this work, following the second way, we automatically learn representations of text and stance information from response and forwarding (users' behaviour) based on multi-task learning for fake news detection.\nStance Detection The researches BIBREF22, BIBREF23 demonstrate that the stance detected from fake news can serve as an effective credibility indicator to improve the performance of fake news detection. The common way of stance detection in rumors is to catch deep semantics from text content based on neural networksBIBREF24. For instance, Kochkina et al.BIBREF25 project branch-nested LSTM model to encode text of each tweet considering the features and labels of the predicted tweets for stance detection, which reflects the best performance in RumourEval dataset. In this work, we utilize transformer encoder to acquire semantics from responses and forwarding of fake news for stance detection.\nMulti-task Learning A collection of improved models BIBREF26, BIBREF27, BIBREF28 are developed based on multi-task learning. Especially, shared-private model, as a popular multi-task learning model, divides the features of different tasks into private and shared spaces, where shared features, i.e., task-irrelevant features in shared space, as supplementary features are used for different tasks. Nevertheless, the shared space usually mixes some task-relevant features, which makes the learning of different tasks introduce noise. To address this issue, Liu et al. BIBREF29 explore an adversarial shared-private model to alleviate the shared and private latent feature spaces from interfering with each other. However, these models transmit all shared features in the shared layer to related tasks without distillation, which disturb specific tasks due to some useless and even harmful shared features. How to solve this drawback is the main challenge of this work.\nExist studies for fake news detection can be roughly summarized into two categories. The first category is to extract or construct comprehensive and complex features with manual ways (Castillo et al., 2011; Ruchansky et al., 2017; Flintham et al., 2018).

        "answer": "FKGL measures the readability of the output.",
        "evidence": "We evaluate the performance of text simplification using neural machine translation on available parallel sentences and additional simplified sentences.\nDataset. We use two simplification datasets (WikiSmall and WikiLarge). WikiSmall consists of ordinary and simplified sentences from the ordinary and simple English Wikipedias, which has been used as benchmark for evaluating text simplification BIBREF17 , BIBREF18 , BIBREF8 . The training set has 89,042 sentence pairs, and the test set has 100 pairs. WikiLarge is also from Wikipedia corpus whose training set contains 296,402 sentence pairs BIBREF19 , BIBREF20 . WikiLarge includes 8 (reference) simplifications for 2,359 sentences split into 2,000 for development and 359 for testing.\nMetrics. Three metrics in text simplification are chosen in this paper. BLEU BIBREF5 is one traditional machine translation metric to assess the degree to which translated simplifications differed from reference simplifications. FKGL measures the readability of the output BIBREF23 . A small FKGL represents simpler output. SARI is a recent text-simplification metric by comparing the output against the source and reference simplifications BIBREF20 .\nWe evaluate the output of all systems using human evaluation. The metric is denoted as Simplicity BIBREF8 . The three non-native fluent English speakers are shown reference sentences and output sentences. They are asked whether the output sentence is much simpler (+2), somewhat simpler (+1), equally (0), somewhat more difficult (-1), and much more difficult (-2) than the reference sentence.\nMethods. We use OpenNMT BIBREF24 as the implementation of the NMT system for all experiments BIBREF5 . We generally follow the default settings and training procedure described by Klein et al.(2017). We replace out-of-vocabulary words with a special UNK symbol. At prediction time, we replace UNK words with the highest probability score from the attention layer. OpenNMT system used on parallel data is the baseline system. To obtain a synthetic parallel training set, we back-translate a random sample of 100K sentences from the collected simplified corpora. OpenNMT used on parallel data and synthetic data is our model. The benchmarks are run on a Intel(R) Core(TM) i7-5930K CPU@3.50GHz, 32GB Mem, trained on 1 GPU GeForce GTX 1080 (Pascal) with CUDA v. 8.0.\nWe choose three statistical text simplification systems. PBMT-R is a phrase-based method with a reranking post-processing step BIBREF18 . Hybrid performs sentence splitting and deletion operations based on discourse representation structures, and then simplifies sentences with PBMT-R BIBREF25 . SBMT-SARI BIBREF19 is syntax-based translation model using PPDB paraphrase database BIBREF26 and modifies tuning function (using SARI). We choose two neural text simplification systems. NMT is a basic attention-based encoder-decoder model which uses OpenNMT framework to train with two LSTM layers, hidden states of size 500 and 500 hidden units, SGD optimizer, and a dropout rate of 0.3 BIBREF8 . Dress is an encoder-decoder model coupled with a deep reinforcement learning framework, and the parameters are chosen according to the original paper BIBREF20 . For the experiments with synthetic parallel data, we back-translate a random sample of 60 000 sentences from the collected simplified sentences into ordinary sentences. Our model is trained on synthetic data and the available parallel data, denoted as NMT+synthetic.\nResults. Table 1 shows the results of all models on WikiLarge dataset. We can see that our method (NMT+synthetic) can obtain higher BLEU, lower FKGL and high SARI compared with other models, except Dress on FKGL and SBMT-SARI on SARI. It verified that including synthetic data during training is very effective, and yields an improvement over our baseline NMF by 2.11 BLEU, 1.7 FKGL and 1.07 SARI. We also substantially outperform Dress, who previously reported SOTA result. The results of our human evaluation using Simplicity are also presented in Table 1. NMT on synthetic data is significantly better than PBMT-R, Dress, and SBMT-SARI on Simplicity. It indicates that our method with simplified data is effective at creating simpler output.\nResults on WikiSmall dataset are shown in Table 2. We see substantial improvements (6.37 BLEU) than NMT from adding simplified training data with synthetic ordinary sentences. Compared with statistical machine translation models (PBMT-R, Hybrid, SBMT-SARI), our method (NMT+synthetic) still have better results, but slightly worse FKGL and SARI. Similar to the results in WikiLarge, the results of our human evaluation using Simplicity outperforms the other models. In conclusion, Our method produces better results comparing with the baselines, which demonstrates the effectiveness of adding simplified training data.\nFKGL measures the readability of the output (Kincaid et al., 1975).",

The group is designated as a terrorist group by the United Nations Security Council, the North Atlantic Treaty Organization (NATO), the European Union, and various other countries. Under bin Laden, Al-Qaeda was responsible for the September 11 attacks in the United States and many other mass-casualty attacks worldwide.\n\nAs a member of the wealthy Bin Laden family, Osama bin Laden was born in Saudi Arabia. His father was Mohammed bin Awad bin Laden, a Saudi millionaire from Hadhramaut, Yemen, and the founder of the construction company, Saudi Binladin Group. His mother, Alia Ghanem, was from a secular middle-class family in Latakia, Syria. He studied at university in the country until 1979, when he joined the Mujahideen forces in Pakistan fighting against the Soviet Union in Afghanistan. He helped to fund the Mujahideen by funneling arms, money, and fighters from the Arab world into Afghanistan, and gained popularity among many Arabs. In 1988, he formed al-Qaeda. He was banished from Saudi Arabia in 1992, lost his Saudi citizenship in 1994, and shifted his base to Sudan until US pressure forced him to leave in 1996. After establishing a new base in Afghanistan, he declared a war against the United States, launching a series of bombings and other violent related attacks. His involvement in the 1998 US embassy bombings landed him on the American Federal Bureau of Investigation's (FBI) lists of Ten Most Wanted Fugitives and Most Wanted Terrorists.\n\nBin Laden masterminded the September 11 attacks, which killed nearly 3,000 people and led President George W. Bush to invade Afghanistan and launch the \"War on Terror\". He became the subject of a decade-long international manhunt, during which the FBI offered a $25 million bounty on him. On 2 May 2011, he was killed by U.S. special operations forces at his compound in Abbottabad, Pakistan.\n\nA highly influential ideologue, bin Laden was able to first acquire sympathizers in the Islamic World due to his status a war-hero of the Afghan Jihad and subsequent focus on attacking Western imperialism. His targeting of civilians and hostile activities against Western governments have made him a reviled figure in the Western world and Western culture, and his role in the September 11 attacks has made public opinion of him in the United States unequivocally negative.",

He was an altar boy at the St. Joseph's Church and was seven when he received his First Communion from Pope Pius XII in the Vatican. He spent sixth and seventh grades at the Fessenden School, where he was a mediocre student, and eighth grade at Cranwell Preparatory School; both schools located in Massachusetts. He was the youngest child and his parents were affectionate toward him, but they also compared him unfavorably with his older brothers. Between the ages of eight and sixteen, Ted suffered the traumas of his sister Rosemary's failed lobotomy and the deaths of two siblings: Joseph Jr. in World War II and Kathleen in an airplane crash. Ted's affable maternal grandfather, John F. Fitzgerald, was the Mayor of Boston, a U.S. Congressman, and an early political and personal influence. Ted spent his four high-school years at Milton Academy, a preparatory school in Milton, Massachusetts, where he received B and C grades. In 1950, he finished 36th in a graduating class of 56. He did well at football there, playing on the varsity in his last two years; the school's headmaster later described his play as \"absolutely fearless ... he would have tackled an express train to New York if you asked ... he loved contact sports\".

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nSpecifically, we employ the integrated gradients method (Sundararajan et al., 2017) to attribute the output to the input words with the integration of first-order derivatives.",

We have also tested the SemEval-cQA-2016 model and had a similar drop in performance on RQE data. This could be explained by the different types of data leading to wrong internal conceptualizations of medical terms and questions in the deep neural layers. This performance drop could also be caused by the complexity of the test consumer health questions that are often composed of several subquestions, contain contextual information, and may contain misspellings and ungrammatical sentences, which makes them more difficult to process BIBREF48 .

        "evidence": "With the widespread adoption of electronic health records (EHRs), medical data are being generated and stored digitally in vast quantities BIBREF0. While much EHR data are structured and amenable to analysis, there appears to be limited homogeneity in data completeness and quality BIBREF1, and it is estimated that the majority of healthcare data are being generated in unstructured, text-based format BIBREF2. The generation and storage of these unstructured data come concurrently with policy initiatives that seek to utilize preventative measures to reduce hospital admission and readmission BIBREF3.\nChronic illnesses, behavioral factors, and social determinants of health are known to be associated with higher risks of hospital readmission, BIBREF4 and though behavioral factors and social determinants of health are often determined at the point of care, their identification may not always be curated in structured format within the EHR in the same manner that other factors associated with routine patient history taking and physical examination are BIBREF5. Identifying these patient attributes within EHRs in a reliable manner has the potential to reveal actionable associations which otherwise may remain poorly defined.\nAs EHRs act to streamline the healthcare administration process, much of the data collected and stored in structured format may be those data most relevant to reimbursement and billing, and may not necessarily be those data which were most relevant during the clinical encounter. For example, a diabetic patient who does not adhere to an insulin treatment regimen and who thereafter presents to the hospital with symptoms indicating diabetic ketoacidosis (DKA) will be treated and considered administratively as an individual presenting with DKA, though that medical emergency may have been secondary to non-adherence to the initial treatment regimen in the setting of diabetes. In this instance, any retrospective study analyzing only the structured data from many similarly selected clinical encounters will necessarily then underestimate the effect of treatment non-adherence with respect to hospital admissions.\nWhile this form of high context information may not be found in the structured EHR data, it may be accessible in patient notes, including nursing progress notes and discharge summaries, particularly through the utilization of natural language processing (NLP) technologies. BIBREF6, BIBREF7 Given progress in NLP methods, we sought to address the issue of unstructured clinical text by defining and annotating clinical phenotypes in text which may otherwise be prohibitively difficult to discern in the structured data associated with the text entry. For this task, we chose the notes present in the publicly available MIMIC database BIBREF8.\nGiven the MIMIC database as substrate and the aforementioned policy initiatives to reduce unnecessary hospital readmissions, as well as the goal of providing structure to text, we elected to focus on patients who were frequently readmitted to the ICU BIBREF9. In particular, a patient who is admitted to the ICU more than three times in a single year. By defining our cohort in this way we sought to ensure we were able to capture those characteristics unique to the cohort in a manner which may yield actionable intelligence on interventions to assist this patient population.\nGiven the MIMIC database as substrate and the aforementioned policy initiatives to reduce unnecessary hospital readmissions, as well as the goal of providing structure to text, we elected to focus on patients who were frequently readmitted to the ICU (Ryan et al., 2015).",

After flowing through Piediluco lake near the community of Marmore (italian), it pours into the valley below formed by the river Nera. The flow of the waterfall depends on an off and on scale with a published schedule to support the power company nearby.\n\nMost of the time, the water in the canals above the Cascata delle Marmore falls is diverted to a hydroelectric power plant, so the flow in the falls themselves is heavily reduced. Piediluco Lake, above the falls, is used as a reservoir for the power plant. The Galleto power plant, built in 1929, is architecturally interesting. Its capacity is about 530 MW. To control the operation of the power plant, and to satisfy tourists, the falls are turned on according to a set schedule, achieving a spectacular effect at full flow. An alarm is sounded first, then the gates are opened, and in a few minutes the small stream is transformed into a full-sized river rushing into the void below.\n\nNormally, the falls are turned on between 12:00 and 13:00 and again between 16:00 and 17:00 every day, with additional times on holidays.

The task is to generate an inflected word form given its lemma and the context in which it occurs.\nMorphological (re)inflection from context is of particular relevance to the field of computational linguistics: it is compelling to estimate how well a machine-learned system can capture the morphosyntactic properties of a word given its context, and map those properties to the correct surface form for a given lemma.\nThere are two tracks of Task 2 of CoNLL–SIGMORPHON 2018: in Track 1 the context is given in terms of word forms, lemmas and morphosyntactic descriptions (MSD); in Track 2 only word forms are available. See Table TABREF1 for an example. Task 2 is additionally split in three settings based on data size: high, medium and low, with high-resource datasets consisting of up to 70K instances per language, and low-resource datasets consisting of only about 1K instances.\nThe baseline provided by the shared task organisers is a seq2seq model with attention (similar to the winning system for reinflection in CoNLL–SIGMORPHON 2016, BIBREF1 ), which receives information about context through an embedding of the two words immediately adjacent to the target form. We use this baseline implementation as a starting point and achieve the best overall accuracy of 49.87 on Task 2 by introducing three augmentations to the provided baseline system: (1) We use an LSTM to encode the entire available context; (2) We employ a multi-task learning approach with the auxiliary objective of MSD prediction; and (3) We train the auxiliary component in a multilingual fashion, over sets of two to three languages.\nIn analysing the performance of our system, we found that encoding the full context improves performance considerably for all languages: 11.15 percentage points on average, although it also highly increases the variance in results. Multi-task learning, paired with multilingual training and subsequent monolingual finetuning, scored highest for five out of seven languages, improving accuracy by another 9.86% on average.\nWe use this baseline implementation as a starting point and achieve the best overall accuracy of 49.87 on Task 2 by introducing three augmentations to the provided baseline system",

        "answer": "It has been shown that one can significantly increase the semantic information carried by a NER system when they successfully linking entities from a deep learning method to the related entities from a knowledge base.",
        "evidence": "Over the few past years, the emergence of deep neural networks has fundamentally changed the design of entity detection systems. Consequently, recurrent neural networks (RNN) have found popularity in the field since they are able to learn long term dependencies of sequential data. The recent success of neural network based architectures principally comes from its deep structure. Training a deep neural network, however, is a difficult problem due to vanishing or exploding gradients. In order to solve this, LSTMs were proposed. An LSTM is an internal memory cell controlled by forget gate and input gate networks. A forget gate in an LSTM layer which determines how much prior memory should be passed into the next time increment. Similarly, an input gate scales new input to memory cells. Depending on the states of both gates, LSTM is able to capture long-term or short-term dependencies for sequential data. This is an ideal property for many NLP tasks.\nMost existing studies consider NER and entity linking as two separate tasks, whereas we try to combine the two. It has been shown that one can significantly increase the semantic information carried by a NER system when we successfully linking entities from a deep learning method to the related entities from a knowledge base (Ji et al., 2018;  Phan et al., 2018).",

        "evidence": "We aimed to mimic the presence of sparse/noisy content distribution, mandating the need to curate a novel dataset via specific lexicons. We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation. With increasing the number of iterations, the pool of seed phrases gets refined and augments the selection of transport relevant tweets. The proposed pipeline is tailored to identify complaint relevant tweets in a noisy scenario.\nIn order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset.",

        "answer": "As stated in the intro, “[the] agent is equipped with .... intents that can be easily translated into human-intelligible requests”. Asking a question is to convey an information-seeking intention. We never assume the human to be omniscient: they know the agent’s *environment* state and goal, but they do not know its inner state.",
        "evidence": "Human-agent communication at deployment time has been under-explored in machine learning, where the traditional focus has been on building agents that can accomplish tasks on their own (full autonomy). Nevertheless, enabling an agent to exchange information with humans during its operation can potentially enhance its helpfulness and trustworthiness. The ability to request and interpret human advice would help the agent accomplish tasks beyond its built-in knowledge, while the ability to accurately convey when and why it is about to fail would make the agent safer to use.\nIn his classical work, outlines the desired characteristics of cooperative communication, commonly known as the Gricean maxims of cooperation. Among these characteristics are informativeness (the maxim of quantity) and faithfulness (the maxim of quality). Human-agent communication in current work has fallen short in these two aspects. Traditional frameworks like imitation learning and reinforcement learning employ limited communication protocols where the agent and the human can only exchange simple intentions (requesting low-level actions or rewards;). More powerful frameworks like allow the agent to process high-level instructions from humans, but the agent still only requests generic help. Recent work in natural language processing endows the agent with the ability to generate rich natural language utterances, but the communication is not faithful in the sense that the agent only mirrors human-generated utterances without grounding its communication in self-perception of its (in)capabilities and (un)certainties. Essentially it learns to convey what a human may be concerned about, not what it is concerned about. This paper presents a hierarchical reinforcement learning framework named HARI (Human-Assisted Reinforced Interaction), which supports richer and more faithful human-agent communication. Our framework allows the agent to learn to convey intrinstic needs for specific information and to incorporate diverse types of information from humans to make better decisions. Specifically, the agent in HARI is equipped with three information-seeking intentions: in every step, it can choose to request more information about (i) its current state, (ii) the goal state, or (iii) a subgoal state which, if reached, helps it make progress on the current task. Upon receiving a request, the human can transfer new information to the agent by giving new descriptions of the requested state. These de- Initially (A) it may request more information about the goal, but may not know enough about where it currently is. For example, at location B, due to limited perception, it does not recognize that it is in a living room and stands next to a couch. It can obtain such information from the assistant.\nIf the current task becomes too difficult (like at location C), the agent can require the assistant to provide a simpler subtask which, if accomplished, helps it make progress on the main task. The agent maintains a stack of tasks and always executes the task at the top. When the agent receives a (sub)task, it pushes the (sub)task to the top of the stack. When it wants to stop executing a (sub)task, it pops the (sub)task from the stack (e.g., at location D). At location E, the agent empties the stack and terminates its execution.\nscriptions will be incorporated as new inputs to the agent's decision-making policy. The human thus can transfer any form of information that can be interpreted by the policy (e.g., asking the agent to execute skills that it has learned, giving side information that connects the agent to a situation it is more familiar with). Because the agent's policy can implement a variety of model architectures and learning algorithms, our framework opens up many possibilities for human-agent communication.\nTo enable faithful communication, we teach the agent to understand its intrinsic needs by interacting with the human and the environment (rather than imitating human behaviors). By requesting different types of information and observing how much each type of information enhances its decisions, the agent gradually learns to determine which information is most useful to obtain in a given situation. With this capability, at deployment time, it can choose when and what information to ask from the human to improve its task performance. To demonstrate the effectiveness of HARI, we simulate a human-assisted navigation problem where an agent has access to only sparse information about its current state and the goal, and can request additional information about these states. On tasks that take place in previously unseen environments, the ability to ask for help improves the agent's success rate by 7× higher compared to performing tasks only by itself. This human-assisted agent even outperforms an agent that always has access to dense information in unseen environments, thanks to the ability to request subgoals. We show that performance of the agent can be further improved by recursively asking for subgoals of subgoals. We discuss limitations of the policy's model and feature representation, which suggest room for future improvements.\nSpecifically, the agent in HARI is equipped with three information-seeking intentions: in every step, it can choose to request more information about (i) its current state, (ii) the goal state, or (iii) a subgoal state which, if reached, helps it make progress on the current task.",

All the models perform very well in BPRA on DSTC2 dataset. On Maluuba dataset, the BPRA decreases because of the complex domains. We can notice that BPRA of CDM is slightly worse than other models on Maluuba dataset, the reason is that the CDM's dialogue policy maker contains lots of classifications and has the bigger loss than other models because of complex domains, which affects the training of the dialogue belief tracker.\nAPRA Results: Compared with baselines, GDP achieves the best performance in APRA on two datasets. It can be noted that we do not compare with the E2ECM baseline in APRA. E2ECM only uses a simple classifier to recognize the label of the acts and ignores the parameters information. In our experiment, APRA of E2ECM is slightly better than our method. Considering the lack of parameters of the acts, it's unfair for our GDP method. Furthermore, the CDM baseline considers the parameters of the act. But GDP is far better than CDM in supervised learning and reinforcement learning.\nBLEU Results: GDP significantly outperforms the baselines on BLEU. As mentioned above, E2ECM is actually slightly better than GDP in APRA. But in fact, we can find that the language quality of the response generated by GDP is still better than E2ECM, which proves that lack of enough parameters information makes it difficult to find the appropriate sentence template in NLG. It can be found that the BLEU of all models is very poor on Maluuba dataset. The reason is that Maluuba is a human-human task-oriented dialogue dataset, the utterances are very flexible, the natural language generator for all methods is difficult to generate an accurate utterance based on the context. And DSTC2 is a human-machine dialog dataset. The response is very regular so the effectiveness of NLG will be better than that of Maluuba.

The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.\n\nWorld War II was by far the deadliest conflict in history; it resulted in an estimated 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massacres, and disease. In the wake of the Axis defeat, Germany and Japan were occupied, and war crimes tribunals were conducted against German and Japanese leaders.\n\nThe causes of World War II are debated, but contributing factors included the Second Italo-Ethiopian War, Spanish Civil War, Second Sino-Japanese War, Soviet–Japanese border conflicts, the rise of fascism in Europe, and European tensions in the aftermath of World War I. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland. The United Kingdom and France subsequently declared war on Germany on 3 September. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union had partitioned Poland and marked out their \"\"spheres of influence\"\" across Finland, Estonia, Latvia, Lithuania and Romania. From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, in a military alliance with Italy, Japan and other countries called the Axis. Following the onset of campaigns in North Africa and East Africa, and the fall of France in mid-1940, the war continued primarily between the European Axis powers and the British Empire, with war in the Balkans, the aerial Battle of Britain, the Blitz of the United Kingdom, and the Battle of the Atlantic.

How to obtain such sparse subnetwork in real applications?",
        "answer": "1) We used clean images as the training targets since this made it easy to control the learning curves and avoid overfitting. Even using one clean image target, the obtained LIP is practical due to the powerful transferability to other images with no clean ground-truth (discussed in [Cons2.] in detail). 2) We can also use the noisy target in finding the same effective LIPs as long as we perform “early-stopping” in the optimization process. Note that it was the same trick mentioned when training the original DIP for denoising tasks [1] and was identified to be essential to the original DIP’s success in [2]. 3) In fact, our results support both using clean and noisy targets (we added the experiments in Table 4 in the section Supplementary Materials). We actually find there are no large differences between them when sticking to the same appropriate experimental setting. 4) Specifically in Table 4, we conducted the IMP experiments on the DIP model with clean and noisy targets on the same image (F16.png, presented in Figure 13). Note that both DIP optimization iteration numbers are 3000 (the number is recommended by the paper “Deep Image Prior” [1] as ``early stopping”) and prune 20% model parameters every IMP epochs. Interestingly, we find there are no large differences (with PSNR value smaller than 0.05) between the performances of subnetworks with clean and noisy image targets (the sparsity ranges from 0% to 95%). Moreover, we add the experiments to explore the convergence curves of subnetworks obtained from different methods. And we also investigate their sparsity distributions per layer.

Similarly, we define the winning tickets: if a matching subnetwork f (x; m θ) has θ = θ p , then it is the winning tickets under the training algorithm A T .\nIn practice, we find the matching subnetworks in the following ways: 1) IMP on the dense model with only one image (applicable to the image restoration task on the same domain of images); 2) IMP on the dense model with various kinds of images through weight-sharing (applicable to the image restoration tasks on images from different domains); 3) LTH IMP on the dense model with the sub-dataset (applicable to the CS task with pre-trained GANs).\nTicket Finding Objectives When finding LIP subnetwork in untrained DNN, i.e., DIP, there is a problem that may be easily overlooked: what is the target during IMP training? Specifically, since the training target in Eq. 1 for DIP is x (the corrupted image), the model parameters may easily overfit the corrupted image during IMP training if we do not fine-tune the training epochs. Then the obtained mask will contain the information of corrupted images instead of the desired image prior (but we can also find the effective subnetworks by noisy targets, experiments are summarized in Table 3 and 4 in Supplementary Materials). Therefore, we modify the optimization objectives of DIP during IMP training: arg min θ E(f θ (z); x) to ensure that model parameters learn the clean image prior.\nEvaluations of Subnetworks After obtaining the matching subnetwork f (x; m θ), we evaluate their performances by 1) resetting the model parameter θ to initialization weight θ 0 ' 2) adding the mask m to the model; 3) training the model to another N iterations. We evaluate the DIP subnetworks performances mainly through Peak Signal to Noise Ratio (PSNR) values, plus reconstruction errors (defined in for compressive sensing with GANs.\nPruning Methods We use the standard pruning method, which iteratively prune the 20% of the model weight each time. For setting i, our basic algorithm performs IMP over just one single image (i.e., DIP's default setting), and the algorithm is summarized in Algorithm 1 (Appendix). We further design an extended algorithm, that can perform IMP for DIP over multiple images, through backbone weight sharing: the algorithm is outlined in Algorithm 2 (Appendix). We will discuss the algorithm variants in Section 4. For setting ii, we use IMP to find winning tickets in pre-trained GANs, following the routine in. In each iteration of IMP, we will first fine-tune the pre-trained GANs on a (sub-)dataset, prune 20% of the remaining weights, and reset to the pre-trained weights. Note that we also include other pruning methods to compare the effectiveness of the matching subnetworks such as random pruning (randomly generate the sparsity mask m ), and pruning-at-initialization methods, e.g., SNIP.\nWe used clean images as the training targets since this made it easy to control the learning curves and avoid overfitting. Even using one clean image target, the obtained LIP is practical due to the powerful transferability to other image with no clean groundtruth.Moreover, we can use the noisy target in finding the same effective LIPs as long as we perform “early-stopping” in the optimization process. Note that it was the same trick mentioned when training the original DIP for denoising tasks (Ulyanov et al., 2018) and was identified to be essential to the original DIP’s success in (Heckel & Hand, 2019). In Table. 4, we conduct the comparison experiments of clean and noisy image targets (experimental settings are summarized in the caption of the table) and we find that there are no large differences between the results of noisy image targets and clean image targets.****Note that the used image is F16.png, the evaluation metric is PSNR and the training iteration number is 3000 to capture the “early-stopping” phenomenon. The results suggest that there are no large differences (with PSNR value smaller than 0.05) between the performances of subnetworks with clean and noisy image targets (the sparsity ranges from 0% to 95%).****Figure 13: Learning curves using four different training targets: a clean image (Baby.png), the same image added with noises, the same randomly scrambled and white noise. Note that we use four different models: the LIP subnetwork (S = 89%), randomly pruned subnetwork (S = 89%), SNIP subnetwork (S = 89%) and the dense model (S = 0%). And we trained them in isolation in the same experimental settings for 10000 iterations.****We use the standard pruning method (Han et al., 2015), which iteratively prune the 20% of the model weight each time.****We further compare the training convergence curves of different subnetworks on the restoration task.",

With deployment on a mobile device in mind, we evaluate energy usage and inference latency on a Raspberry Pi (which shares the same ARM architecture as nearly all smartphones today). We find that a 2.5 $\\times $ reduction in perplexity on PTB comes at a staggering cost in terms of performance: inference with NLMs takes 49 $\\times $ longer and requires 32 $\\times $ more energy. Furthermore, we find that impressive reductions in perplexity translate into at best modest improvements in next-word prediction, which is arguable a better metric for evaluating software keyboards on a smartphone. The contribution of this paper is the first known elucidation of this quality–performance tradeoff.

While officially, Jim was let go due to \"budgetary constraints\", it was quite clear to him that it had more to do with his age than any financial strain on the school district. See, Jim was born in 1899, he had just turned 75 years old in January and was starting to \"slow down\" on the job. He could no longer do some of the highly intensive labor that his profession often entailed, and it became noticeable. \n\nAfter his last day of work, Jim walked to his home, which conveniently was only three blocks south of the school. On his walk, he couldn't help but feel sad and slightly embarrassed. He knew that his wife, Miriam, would understand, but he felt like he let her and himself down. For nearly 40 years, Jim worked at Elmhurst Elementary School and was beloved by the thousands of students that came through those doors. While he wasn't going to miss cleaning up student's throw-up or a cafeteria that resembled more of a war zone than a public eating space, he was going to miss the children. Watching them learn, play, and grow was always what made the job worth it to him.\n\nWhen Jim walked through the door of his one story home, Miriam was there to greet him. She could tell what had happened by the look on his face. Particularly, she could tell by his eyes. Jim's eyes were a portal into his soul and, as such, a window into his emotions.\n\nAs Jim walked through the living room and into the kitchen, he saw two people, a man and a woman, sitting at the table, and in the woman's arms was a baby. This man was his son, Tommy, who he had not seen since he deployed for the Vietnam War three years prior. Up until this moment, Jim wasn't even sure if his son was alive. Jim's eyes opened wide with sheer elation at the sight, and a tear slowly formed in the corner of his left eye.\n\nOver the next few hours, Jim sat with his son and his family and discussed all that had happened since the last time they had seen each other. Tommy spoke about how he had been designated as MIA by the US government after a particularly brutal ambush during one of his morning patrols. After many months of hiding from the enemy and searching for his unit, Tommy eventually stumbled across one of the final remaining US camps stationed in South Vietnam. It was at this camp that Tommy met his now wife, Sara. She was the nurse who oversaw his recovery. They fell in love immediately, got married, and Sara became pregnant, all before even leaving Vietnam for the United States. Tommy and Sara had returned to the US only a month ago, and their baby was born two weeks later.\n\nWhile Jim laid in bed that night, he couldn't believe all the change that one day could bring.

        "answer": "Genetics is the study of genes, genetic variation, and heredity in organisms. It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied \"trait inheritance\", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete \"units of inheritance\". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.\n\nTrait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including molecular genetics, epigenetics and population genetics. Organisms studied within the broad field span the domains of life (archaea, bacteria, and eukarya).\n\nGenetic processes work in combination with an organism's environment and experiences to influence development and behavior, often referred to as nature versus nurture. The intracellular or extracellular environment of a living cell or organism may increase or decrease gene transcription. A classic example is two seeds of genetically identical corn, one placed in a temperate climate and one in an arid climate (lacking sufficient waterfall or rain). While the average height of the two corn stalks may be genetically determined to be equal, the one in the arid climate only grows to half the height of the one in the temperate climate due to lack of water and nutrients in its environment.",

Offensive language can be categorized as: Vulgar, which include explicit and rude sexual references, Pornographic, and Hateful, which includes offensive remarks concerning people’s race, religion, country, etc. BIBREF14. Prior works have concentrated on building annotated corpora and training classification models. Concerning corpora, hatespeechdata.com attempts to maintain an updated list of hate speech corpora for multiple languages including Arabic and English. Further, SemEval 2019 ran an evaluation task targeted at detecting offensive language, which focused exclusively on English BIBREF15. As for classification models, most studies used supervised classification at either word level BIBREF10, character sequence level BIBREF11, and word embeddings BIBREF9. The studies used different classification techniques including using Naïve Bayes BIBREF10, SVM BIBREF11, and deep learning BIBREF6, BIBREF7, BIBREF12 classification. The accuracy of the aforementioned system ranged between 76% and 90%. Earlier work looked at the use of sentiment words as features as well as contextual features BIBREF13.\nThe work on Arabic offensive language detection is relatively nascent BIBREF16, BIBREF17, BIBREF18, BIBREF19, BIBREF5. Mubarak et al. mubarak2017abusive suggested that certain users are more likely to use offensive languages than others, and they used this insight to build a list of offensive Arabic words and they constructed a labeled set of 1,100 tweets. Abozinadah et al. abozinadah2017detecting used supervised classification based on a variety of features including user profile features, textual features, and network features. They reported an accuracy of nearly 90%. Alakrot et al. alakrot2018towards used supervised classification based on word unigrams and n-grams to detect offensive language in YouTube comments. They improved classification with stemming and achieved a precision of 88%. Albadi et al. albadi2018they focused on detecting religious hate speech using a recurrent neural network.

Later in the ablation studies the authors do however check for this, but the conclusion from Table 3 is mainly that all factors contributed (at least a bit), where the Fidelity and Variety criterion seemed to have contributed the least. So is it not super fair to state that the model's superior performance is (only) thanks to adaptive augmentation selection? In fact, from Fig. 7 it even seems that the model just learns to select one best augmentation, rather than a best combination of all of them.",
        "answer": "The reason is that the basic augmentations are adopted from a previous paper [14], which have been manually tuned to generate relatively good performances for contrastive learning. For these reasons, significant improvements on different variants of our methods are impractical and unreasonable. In the initial version, we have conducted some experiments on classification, using both good and bad basic augmentations. As shown in Figure 3, augmentations with high variety and high fidelity can also achieve good accuracy performance with significant improvement. To further take the reviewers' comments into consideration, we have conducted more experiments to show the effectiveness of each component with both good and bad basic augmentations in Appendix D. As is shown In Table 8, comparing to \"Random'', which is not trained with variety and fidelity objectives, our InfoTS significantly increases the performances. For example, \"Random'' gets 0.384 averaged MAE, while our InfoTS achieves 0.370 average MAE achieved.  We also report other variants to further empirically demonstrate that both variety and fidelity make contributions to the superior performances of InfoTS.",
        "evidence": "In Section 2.2, we propose criteria of data augmentations for time series based on information theory that good augmentations should have high variety and fidelity. With mutual information neural estimation and cross-entropy as approximations, we get the criteria in Eq. (5). To empirically verify the effectiveness of the proposed criteria, we adopt the dataset CricketX from the UCR archive (Dau et al., 2019; Fan et al., 2020), and conduct augmentations with different configurations, such as jittering with noise from N (0, 0.3) and cutout 10% time stamps. For each configuration, we calculate the criteria score and the corresponding classification accuracy within the setting in Section 4.2. As shown in Figure 3, in general, accuracy performance is positively related to the proposed criteria in both supervised and unsupervised settings, verifying the correctness of using the criteria as the objective in the meta-network training.****With the proposed criteria, we empirically show the advantage of the developed meta-network on learning optimal augmentations. The overall observations are consistent with ones from Section 4.4. Here, we provide more details. 1) “Random” is a variant that randomly selects a candidate augmentation method to generate augmented instances. “All” combines all candidate augmentations evenly to generate augmented instances. These two variances are routinely utilized in previous works (Chen et al., 2020; You et al., 2020). They work well when candidate augmentations are manually verified. Otherwise, their performances are heavily affected by the low-quality candidate augmentations, as shown in Tabel 8. On the other hand, by adaptively selecting optimal augmentations, InfoTS significantly improve the forecasting performances even with low-quality candidate augmentations. 2) By comparing InfoTS to its variant w/o Fidelity and w/o Variety, we further empirically demonstrate that both variety and fidelity make contributions to the superior performances of InfoTS.",

        "answer": "Yes.",
        "evidence": "Neural machine translation has attracted much attention in recent years BIBREF0, BIBREF1, BIBREF2, BIBREF3. Given a sentence $x=(x_1, \\dots ,x_{T_x})$ from the source language, the straight-forward way for translation is to generate the target words $y=(y_1, \\dots , y_{T_y})$ one by one from left to right. This is also known as the AutoRegressive Translation (ART) models, in which the joint probability is decomposed into a chain of conditional probabilities:\nWhile the ART models have achieved great success in terms of translation quality, the time consumption during inference is still far away from satisfactory. During training, the predictions at different positions can be estimated in parallel since the ground truth pair $(x,y)$ is exposed to the model. However, during inference, the model has to generate tokens sequentially as $y_{<t}$ must be inferred on the fly. Such autoregressive behavior becomes the bottleneck of the computational time BIBREF4.\nIn order to speed up the inference process, a line of works begin to develop non-autoregressive translation models. These models break the autoregressive dependency by decomposing the joint probability with\nThe lost of autoregressive dependency largely hurt the consistency of the output sentences, increase the difficulty in the learning process and thus lead to a low quality translation. Previous works mainly focus on adding different components into the NART model to improve the expressiveness of the network structure to overcome the loss of autoregressive dependency BIBREF5, BIBREF6, BIBREF7. However, the computational overhead of new components will hurt the inference speed, contradicting with the goal of the NART models: to parallelize and speed up neural machine translation models.\nTo tackle this, we proposed a novel hint-based method for NART model training. We first investigate the causes of the poor performance of the NART model. Comparing with the ART model, we find that: (1) the positions where the NART model outputs incoherent tokens will have very high hidden states similarity; (2) the attention distributions of the NART model are more ambiguous than those of ART model. Therefore, we design two kinds of hints from the hidden states and attention distributions of the ART model to help the training of the NART model. The experimental results show that our model achieves significant improvement over the NART baseline models and is even comparable to a strong ART baseline in BIBREF4.\nComparing with the ART model, we find that: (1) the positions where the NART model outputs incoherent tokens will have very high hidden states similarity; (2) the attention distributions of the NART model are more ambiguous than those of ART model.",

As the baseline features released in the WMT2018 QE Shared Task for English-Latvian are incomplete, we train our CEQE model without using such features. We can glean several observations from this data:\nBecause the number of “OK” tags is much larger than the number of “BAD” tags, the model is easily biased towards predicting the “OK” tag for each target word. The F1-OK scores are higher than the F1-BAD scores across all the language pairs.\nFor German-English, English Czech, and English-German (SMT), adding the baseline features can significantly improve the F1-BAD scores.\nFor English-Czech, English-German (SMT), and English-German (NMT), removing POS tags makes the model more biased towards predicting “OK” tags, which leads to higher F1-OK scores and lower F1-BAD scores.\nAdding the convolution layer helps to boost the performance of F1-Multi, especially on English-Czech and English-Germen (SMT) tasks. Comparing the F1-OK scores of the model with and without the convolution layer, we find that adding the convolution layer help to boost the F1-OK scores when translating from English to other languages, i.e., English-Czech, English-German (SMT and NMT).

        "question": "What planning should you do to visit Walt Disney World?",
        "evidence": "",
        "answer": "You should start planning your Walt Disney World vacation at least six months in advance.  First figure out your travel arrangements.  If you are able to drive, you will have your own vehicle available to travel to the parks.  If you fly, you will either need a rental car or will need to use other forms of transportation, such as uber or lyft.  Within the Walt Disney World parks and resorts there is Disney provided transportation, but it is often crowded during peak hours such as park opening and closing.  Next you will need to decide where to stay.  The Walt Disney World resorts are the most convenient, but also the most expensive option.  There are Walt Disney World resorts cater to different economic levels from more affordable up to more luxurious.  Staying on the grounds will also often allow to enter parks earlier or stay later than the general public.  Staying off the grounds is usually less expensive.  There are many hotels and resorts in the Orlando area to choose from.  Other options are to use a rental service such as VRBO or AirBnB to rent a property such as a house or condo for your stay.  Next you need to decide on how many days in the parks you'll spend and whether you will stay in one park for an entire day or want to have the option to \"park hop\".  Tickets are discounted for a larger number of days in the park.  The \"park hopper\" option is a premium on top of the base ticket price.  Often there are discount ticket websites but be careful about scams.  The safest is to buy from Disney or a licensed travel advisor.  Typically the price from a travel advisor is they same as buying from Disney.  Next make a budget for how much you'll spend on food in the parks.  Food is fairly pricy, but there are options from counter service all the way up to sit down restaurants and fine dining.  Realize that eating in a sit down restaurant will take time away from other activities in the parks.  Reservations can be made on the Disney website but are often difficult to get for some restaurants.  Taking food into the park is also an option as there are lockers available at the parks to store things.  Some items such as knives are not allowed, so plan ahead if food needs to be sliced.  Next look at the rides and attractions that your family wants to ride and make a plan for which are the most important.  A guidebook such as the Unauthorized Guide to Disney World is very helpful to provide plans for your day(s) in the parks.  These guidebooks will give you help on when the lines for attractions will be shorter.  Don't just try to show up in a park without some sort of plan as to which attractions to visit and when.  Visiting without a plan will result in frustration, long waits, and disappointment.  Also realize that you will not be able to visit all of the park attractions in one visit.  As the time of your visit approaches watch the weather reports.  Late afternoon thunderstorms are typical in Orlando in the summertime.  Most attractions at Disney World are indoors and will continue operating during rain.  Rain ponchos can be purchased in the park, but they are more expensive in park than if you bring your own.  It can also be very hot during the summer, so plan on having water, sunscreen and wearing appropriate clothing for the weather.  Be aware of how your party's attitude is during your visit.  Visiting Disney World requires a lot of walking and also requires stamina.  If people are getting tired, take a break, either in the park or back at your hotel.  Don't make your visit a \"death march\".  Also base the length of your stay in the park on the age of people in your party.  Young children or elderly may require longer and more frequent breaks.  One option is to go to the park in the morning, go back to your hotel in the afternoon for a dip in the pool, and return to the park later afternoon or evening.  Pay attention to the park hours to know how early you can arrive and how late you can stay.  Most parks have some sort of parade and fireworks show at closing.  Most are very worthwhile to see.  And remember above all that you should have fun.  Don't be so focused on your plan of visiting attractions that you don't take advantage of spur of the moment opportunities such as interacting with characters or getting a quick photo with the family.  Hopefully this will not be your only vacation at Disney World, and you want to have fond memories of your visit so that you will want to return again as soon as possible.",

        "evidence": "The goal of the summarization task is condensing a piece of text into a shorter version that covers the main points succinctly. In the abstractive approach important pieces of information are presented using words and phrases not necessarily appearing in the source text. This requires natural language generation techniques with high level of semantic understanding BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6.\nMajor research efforts have focused so far on summarization of single-speaker documents like news (e.g., BIBREF7) or scientific publications (e.g., BIBREF8). One of the reasons is the availability of large, high-quality news datasets with annotated summaries, e.g., CNN/Daily Mail BIBREF9, BIBREF7. Such a comprehensive dataset for dialogues is lacking.\nThe challenges posed by the abstractive dialogue summarization task have been discussed in the literature with regard to AMI meeting corpus BIBREF10, e.g. BIBREF11, BIBREF12, BIBREF13. Since the corpus has a low number of summaries (for 141 dialogues), BIBREF13 proposed to use assigned topic descriptions as gold references. These are short, label-like goals of the meeting, e.g., costing evaluation of project process; components, materials and energy sources; chitchat. Such descriptions, however, are very general, lacking the messenger-like structure and any information about the speakers.\nTo benefit from large news corpora, BIBREF14 built a dialogue summarization model that first converts a conversation into a structured text document and later applies an attention-based pointer network to create an abstractive summary. Their model, trained on structured text documents of CNN/Daily Mail dataset, was evaluated on the Argumentative Dialogue Summary Corpus BIBREF15, which, however, contains only 45 dialogues.\nIn the present paper, we further investigate the problem of abstractive dialogue summarization. With the growing popularity of online conversations via applications like Messenger, WhatsApp and WeChat, summarization of chats between a few participants is a new interesting direction of summarization research. For this purpose we have created the SAMSum Corpus which contains over 16k chat dialogues with manually annotated summaries. The dataset is freely available for the research community.\nThe paper is structured as follows: in Section SECREF2 we present details about the new corpus and describe how it was created, validated and cleaned. Brief description of baselines used in the summarization task can be found in Section SECREF3. In Section SECREF4, we describe our experimental setup and parameters of models. Both evaluations of summarization models, the automatic with ROUGE metric and the linguistic one, are reported in Section SECREF5 and Section SECREF6, respectively. Examples of models' outputs and some errors they make are described in Section SECREF7. Finally, discussion, conclusions and ideas for further research are presented in sections SECREF8 and SECREF9.\nIn the present paper, we further investigate the problem of abstractive dialogue summarization.",

        "evidence": "Slavery ended in the United States in 1865 with the end of the American Civil War and the ratification of the Thirteenth Amendment to the United States Constitution, which declared that \"Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction\". At that time, an estimated four million African Americans were set free.\n\nSupport for reparations\nWithin the political sphere, a bill demanding slavery reparations has been proposed at the national level, the \"Commission to Study and Develop Reparation Proposals for African-Americans Act,\" which former Rep. John Conyers Jr. (D-MI) reintroduced to the United States Congress every year from 1989 until his resignation in 2017. As its name suggests, the bill recommended the creation of a commission to study the \"impact of slavery on the social, political and economic life of our nation\"., however there are cities and institutions which have initiated reparations in the US (see § Legislation and other actions for a list).\n\nIn 1999, African-American lawyer and activist Randall Robinson, founder of the TransAfrica advocacy organization, wrote that America's history of race riots, lynching, and institutional discrimination have \"resulted in $1.4 trillion in losses for African Americans\". Economist Robert Browne stated the ultimate goal of reparations should be to \"restore the black community to the economic position it would have if it had not been subjected to slavery and discrimination\". He estimates a fair reparation value anywhere between $1.4 to $4.7 trillion, or roughly $142,000 (equivalent to $162,000 in 2021) for every black American living today. Other estimates range from $5.7 to $14.2 and $17.1 trillion.\n\nIn 2014, American journalist Ta-Nehisi Coates published an article titled \"The Case for Reparations\", which discussed the continued effects of slavery and Jim Crow laws and made renewed demands for reparations. Coates refers to Rep. John Conyers Jr.'s H.R.40 Bill, pointing out that Congress's failure to pass this bill expresses a lack of willingness to right their past wrongs.\n\nIn September 2016, the United Nations' Working Group of Experts on People of African Descent encouraged Congress to pass H.R.40 to study reparations proposals. Still, the Working Group did not directly endorse any specific reparations proposal. The report noted that there exists a legacy of racial inequality in the United States, explaining that \"Despite substantial changes since the end of the enforcement of Jim Crow and the fight for civil rights, ideology ensuring the domination of one group over another, continues to negatively impact the civil, political, economic, social and cultural rights of African Americans today.\" The report notes that a \"dangerous ideology of white supremacy inhibits social cohesion among the US population\".\n\nThe topic of reparations gained renewed attention in 2020 as the Black Lives Matter movement named reparations as one of their policy goals in the United States.\n\nIn 2020, rapper T.I. supported reparations that would give every African American US$1 million and asserted that slavery caused mass incarcerations, poverty, and other ills.",
        "answer": "In spite of progressive changes since the end of enforcement of Jim Crow and the successes of the fight for civil rights there are still inherent racial inequalities in the USA which negatively affect the civil, political, economic, social and cultural rights of African Americans today.  A United Nations report of 2016 did not endorse a specific reparations proposal, but did call out that there is an ideology of white supremacy present in the population of the United States that inhibits social cohesion.  Further arguments have been made identifying slavery as a cause of mass incarcerations, poverty and other ills that affect today’s African Americans.\nIt could be argued that there is an inherent acknowledgement that the case exists to examine the impact of slavery on the social, political and economic life of the United States in the annual submission to Congress of the \"Commission to Study and Develop Reparation Proposals for African-Americans Act”.  There are also individual cities within the USA which have instituted reparations.  Estimates of the cost to African Americans of the United States’ history of discrimination have been estimated variously at $1.4 trillion, $4.7 trillion, $5.7 trillion, $14.2 trillion and $17.1 trillion.  These estimates express the projected cost in $ to restore the black community to the economic position it would have if it had not been subjected to slavery and discrimination.",

        "answer": "Rafael Nadal on clay is like a Grand Theft Auto game with the 'Infinite Ammo' cheat code enabled. Several have compared the Spaniard displaying his prowess on the red dirt to Picasso painting a live mural, Ennio Morricone producing a melody exactly congruent with the scenario, or Jorge Lorenzo posting similar times lap after lap in an almost mechanical yet fluid approach.\n\nRafael Nadal's ability on clay is mostly due to the surface itself. This may appear to be a quip, but the particular qualities of claycourts - which distinguish them from grass and hardcourts - are a fundamental reason why Rafael Nadal has dominated the surface the way he has.\n\nWhat distinguishes clay? It's sluggish and bouncy. Fundamentally, clay reduces the speed of the ball once it bounces on the surface. Of course, there's more to it than just making the game slow and monotonous, but that's the distinguishing quality of a claycourt.\n\nThe surface is also less skiddish than grass or hard, allowing the ball to bounce high, which suits Rafael Nadal's high topspin-based game.\n\nThe slick nature of grass and hardcourt surfaces has been one of Rafael Nadal's main challenges throughout his career. Because there is significantly more skid on the ball on grass and hard than on clay, the ball tends to stay low. That in turn takes away vital time from the Spaniard to apply enough topspin.\n\nFor many of Rafael Nadal's career, his allegedly subpar serve in compared to his opponents was regarded as his most serious flaw. When his ground game isn't functioning, Nadal rarely has the luxury of a great first serve that can bail him out of trouble. To save break points, the 19-time Grand Slam champion frequently needs to drag out rallies.\n\nDespite having a somewhat weak serve for the majority of his career, Rafael Nadal has able to take use of his southpaw serve on the ad side (to a right-handed opponent's normally weaker side). And nowhere has he done it better than on his favourite red dirt; just ask Roger Federer how much it sucks for the opponent.\n\nThe southpaw's serve forces the right-handed returner wide into his backhand corner, resulting in a weak return. This opens up practically the entire court for Rafael Nadal to unleash his most lethal weapon, the forehand down the line.\n\nRafael Nadal's obsession with patterns has been a feature of his game throughout his career, regardless of the surface.\n\nIn fact, because he is preoccupied on keeping to his rallying patterns, Nadal sometimes lets go of an opening and misses a chance to strike a winner into the open court. On social media, this has become known as Nadal's \"Open Court atheism.\"",

        "question": "What is a classified board of directors, and why would a company want to implement this type of corporate structure?",
        "evidence": "",
        "answer": "For companies that are incorporated in Delaware, the Delaware General Corporation Law permits corporations to divide their boards of directors into up to 3 classes.  Other states in the United States have similar provisions regarding classified boards.\n\nFor boards that have only 1 class, each director serves a fixed term (generally 1 year), and each director is subject to re-election each year.  \n\nClassified boards (also known as staggered boards) are divided into three separate classes (in equal proportion, to the extent possible), with members of each class serving three-year terms and only one class of directors up for election in any year.  \n\nA classified board is one type of protection that companies consider as part of a wider range review of corporate defensive measures.  Generally, corporate defensive measures relate to measures for a company to consider to protect against (1) hostile takeovers that the board believes do not reflect the value of the company and (2) short-termism, where there is pressure from public investors – particularly activist investors – to take board actions (or face the risk of being voted off the board) that the board believes are not in the best interest of the company and its stockholders and maximizing value over the long term.  Corporate defensive measures generally aren’t relevant when a company is private given the corporate structure with significant long-term investor representation on the board and various agreements in place with stockholders.  However, these measures become relevant once a company has public stockholders, so many companies who are considering an initial public offering will assess what types of defensive measures would be appropriate for them.\n\nA classified board is viewed as corporate defensive measure (i.e., it’s an anti-takeover and activist defense) as the entire board can’t be replaced in a single election cycle (with 3 classes, it would take up to the 3rd election cycle for the full board to be replaced, and generally 2 years to capture a majority).",

We suspect that this is due to the fact that generating entailed sentences has a larger space of valid target sequences, which makes the use of BLEU problematic and penalizes correct solutions. Hence, we manually annotated 100 random test sentences and decided whether the generated sentence can indeed be inferred from the source sentence. We found that sentences generated by an LSTM with attention are substantially more accurate ( $82\\%$ accuracy) than those generated from an LSTM baseline ( $71.7\\%$ ).

        "evidence": "Pronouns can serve a variety of functions with complex cross-lingual variation BIBREF12 , and hand-picked, manually annotated test suites have been presented for the evaluation of pronoun translation BIBREF13 , BIBREF14 , BIBREF9 . While suitable for analysis, the small size of the test suites makes it hard to make statistically confident comparisons between systems, and the hand-picked nature of the test suites introduces biases. To overcome these problems, we opted for a fully automatic approach to constructing a large-scale test suite.\nConceptually, our test set is most similar to the “cross-lingual pronoun prediction” task held at DiscoMT and WMT in recent years BIBREF15 , BIBREF16 , BIBREF17 : participants are asked to fill a gap in a target sentence, where gaps correspond to pronouns.\nThe first edition of the task focused on English INLINEFORM0 French, and it was found that local context (such as the verb group) was a strong signal for pronoun prediction. Hence, future editions only provided target-side lemmas instead of fully inflected forms, which makes the task less suitable to evaluate end-to-end neural machine translation systems, although such systems have been trained on the task BIBREF18 .\n BIBREF17 do not report on the proportion of intra-sentential and inter-sentential anaphora in their test set, but the two top-performing systems only made use of intra-sentential information. Our test suite focuses on allowing the comparison of end-to-end context-aware NMT systems, and we thus extract a large number of inter-sentential anaphora, with meta-data allowing for a focus on inter-sentential anaphora with a long distance between the pronoun and its antecedent. Our focus on evaluating end-to-end NMT systems also relieves us from having to provide annotated training sets, and reduces pressure to achieve balance and full coverage of phenomena.\nAn alternative approach to automatically evaluate pronoun translation are reference-based methods that produce a score based on word alignment between source, translation output, and reference translation, and identification of pronouns in them, such as AutoPRF BIBREF19 and APT BIBREF20 . BIBREF21 perform a human meta-evaluation and show substantial disagreement between reference-based metrics and human judges, especially because there often exist valid alternative translations that use different pronouns than the reference. Our test set, and our protocol of generating contrastive examples, is focused on selected pronouns to minimize the risk of producing contrastive examples that are actually valid translations.\nOur test suite focuses on allowing the comparison of end-to-end contextaware NMT systems, and we thus extract a large number of inter-sentential anaphora, with meta-data allowing for a focus on inter-sentential anaphora with a long distance between the pronoun and its antecedent.",

        "question": "How to train domain-specific word embeddings?",
        "answer": "The authors trained domain-specific word embeddings using the Word2Vec CBOW model (w ∈ R100).",
        "evidence": "First, to operationalize, we say that term $i$ is associated with gender $j$ if, when discussing individuals of gender $j$, $i$ is used with unusual frequency – which we can check with statistical hypothesis tests. Let $f_i$ represent the likelihood of $i$ appearing when discussing women or men. $f_i$ is unknown, but we can model the distribution of all possible $f_i$ using the corpus of texts that we have from the domain. We construct a gender-balanced version of the corpus by randomly undersampling the more prevalent gender until the proportions of each gender are equal. Assuming a non-informative prior distribution on $f_i$, the posterior distribution is Beta($k_i$, $N - k_i$), where $k_i$ is the count of $i$ in the gender-balanced corpus and $N$ is the total count of words in that corpus.\nAs BIBREF10 discuss, “the distribution of the gender-specific counts can be described by an integral over all possible $f_i$. This integral defines the Beta-Binomial distribution BIBREF29, and has a closed form solution.” We say that term $i$ is significantly associated with gender $j$ if the cumulative distribution at $k_{ij}$ (the count of $i$ in the $j$ portion of the gender-balanced corpus) is $p \\le 0.05$. As in the original work, we apply the Bonferroni correction BIBREF30 for multiple comparisons because we are computing statistical tests for thousands of hypotheses.\nFirst, we trained domain-specific word embeddings using the Word2Vec BIBREF33 CBOW model ($w \\in R^{100}$). Then, we used k-means clustering to cluster the embeddings of the gender-associated words. Since k-means may converge at local optima, we ran the algorithm 50 times and kept the model with the lowest sum of squared errors.\nTo automatically label the clusters, we combined the grounded knowledge of WordNet BIBREF34 and context-sensitive strengths of domain-specific word embeddings. Our algorithm is similar to BIBREF28's approach, but we extend their method by introducing domain-specific word embeddings for clustering as well as a new technique for sense disambiguation. Given a cluster, our algorithm proceeds with the following three steps:\nSense disambiguation: The goal is to assign each cluster word to one of its WordNet synsets; let $S$ represent the collection of chosen synsets. We know that these words have been clustered in domain-specific embedding space, which means that in the context of the domain, these words are very close semantically. Thus, we choose $S^*$ that minimizes the total distance between its synsets.\nCandidate label generation: In this step, we generate $L$, the set of possible cluster labels. Our approach is simple: we take the union of all hypernyms of the synsets in $S^*$.\nCandidate label ranking: Here, we rank the synsets in $L$. We want labels that are as close to all of the synsets in $S^*$ as possible; thus, we score the candidate labels by the sum of their distances to each synset in $S^*$ and we rank them from least to most distance.\nIn steps 1 and 3, we use WordNet pathwise distance, but we encourage the exploration of other distance representations as well.\nFirst, we trained domain-specific word embeddings using the Word2Vec (Mikolov et al., 2013) CBOW model (w ∈ R100).",

        "evidence": "The German sociologist Max Weber was the first to formally study bureaucracy and his works led to the popularization of this term. In his essay Bureaucracy, published in his magnum opus Economy and Society, Weber described many ideal-typical forms of public administration, government, and business. His ideal-typical bureaucracy, whether public or private, is characterized by:\n- hierarchical organization\n- formal lines of authority (chain of command)\n- a fixed area of activity\n- rigid division of labor\n- regular and continuous execution of assigned tasks\n- all decisions and powers specified and restricted by regulations\n- officials with expert training in their fields\n- career advancement dependent on technical qualifications\n- qualifications evaluated by organizational rules, not individuals\nWeber listed several preconditions for the emergence of bureaucracy, including an increase in the amount of space and population being administered, an increase in the complexity of the administrative tasks being carried out, and the existence of a monetary economy requiring a more efficient administrative system. The development of communication and transportation technologies makes more efficient administration possible, and democratization and rationalization of culture results in demands for equal treatment. Although he was not necessarily an admirer of bureaucracy, Weber saw bureaucratization as the most efficient and rational way of organizing human activity and therefore as the key to rational-legal authority, indispensable to the modern world. Furthermore, he saw it as the key process in the ongoing rationalization of Western society. Weber also saw bureaucracy, however, as a threat to individual freedoms, and the ongoing bureaucratization as leading to a \"polar night of icy darkness\", in which increasing rationalization of human life traps individuals in a soulless \"iron cage\" of bureaucratic, rule-based, rational control Weber's critical study of the bureaucratization of society became one of the most enduring parts of his work. Many aspects of modern public administration are based on his work, and a classic, hierarchically organized civil service of the Continental type is called \"Weberian civil service\" or \"Weberian bureaucracy\".

However, the structure of gender bias in vector space remains largely intact, and the new vectors still evince indirect bias: associations which result from gender bias between not explicitly gendered words, for example a possible association between football and business resulting from their mutual association with explicitly masculine words BIBREF4. In this paper we continue the work of BIBREF4, and show that another paradigm for gender bias mitigation proposed by BIBREF5, Counterfactual Data Augmentation (CDA), is also unable to mitigate indirect bias. We also show, using a new test we describe (non-biased gender analogies), that WED might be removing too much gender information, casting further doubt on its operationalisation of gender bias as a linear subspace.\nTo improve CDA we make two proposals. The first, Counterfactual Data Substitution (CDS), is designed to avoid text duplication in favour of substitution. The second, the Names Intervention, is a method which can be applied to either CDA or CDS, and treats bias inherent in first names. It does so using a novel name pairing strategy that accounts for both name frequency and gender-specificity. Using our improvements, the clusters of the most biased words exhibit a reduction of cluster purity by an average of 49% across both corpora following treatment, thereby offering a partial solution to the problem of indirect bias as formalised by BIBREF4.

        "evidence": "The race and gender bias evaluation was carried out on the output of the 219 automatic systems that participated in SemEval-2018 Task 1: Affect in Tweets BIBREF5 . The shared task included five subtasks on inferring the affectual state of a person from their tweet: 1. emotion intensity regression, 2. emotion intensity ordinal classification, 3. valence (sentiment) regression, 4. valence ordinal classification, and 5. emotion classification. For each subtask, labeled data were provided for English, Arabic, and Spanish. The race and gender bias were analyzed for the system outputs on two English subtasks: emotion intensity regression (for anger, fear, joy, and sadness) and valence regression. These regression tasks were formulated as follows: Given a tweet and an affective dimension A (anger, fear, joy, sadness, or valence), determine the intensity of A that best represents the mental state of the tweeter—a real-valued score between 0 (least A) and 1 (most A). Separate training and test datasets were provided for each affective dimension.\nTraining sets included tweets along with gold intensity scores. Two test sets were provided for each task: 1. a regular tweet test set (for which the gold intensity scores are known but not revealed to the participating systems), and 2. the Equity Evaluation Corpus (for which no gold intensity labels exist). Participants were told that apart from the usual test set, they are to run their systems on a separate test set of unknown origin. The participants were instructed to train their system on the tweets training sets provided, and that they could use any other resources they may find or create. They were to run the same final system on the two test sets. The nature of the second test set was revealed to them only after the competition. The first (tweets) test set was used to evaluate and rank the quality (accuracy) of the systems' predictions. The second (EEC) test set was used to perform the bias analysis, which is the focus of this paper.\nSystems: Fifty teams submitted their system outputs to one or more of the five emotion intensity regression tasks (for anger, fear, joy, sadness, and valence), resulting in 219 submissions in total. Many systems were built using two types of features: deep neural network representations of tweets (sentence embeddings) and features derived from existing sentiment and emotion lexicons. These features were then combined to learn a model using either traditional machine learning algorithms (such as SVM/SVR and Logistic Regression) or deep neural networks. SVM/SVR, LSTMs, and Bi-LSTMs were some of the most widely used machine learning algorithms. The sentence embeddings were obtained by training a neural network on the provided training data, a distant supervision corpus (e.g., AIT2018 Distant Supervision Corpus that has tweets with emotion-related query terms), sentiment-labeled tweet corpora (e.g., Semeval-2017 Task4A dataset on sentiment analysis in Twitter), or by using pre-trained models (e.g., DeepMoji BIBREF20 , Skip thoughts BIBREF21 ). The lexicon features were often derived from the NRC emotion and sentiment lexicons BIBREF22 , BIBREF23 , BIBREF24 , AFINN BIBREF25 , and Bing Liu Lexicon BIBREF26 .\nWe provided a baseline SVM system trained using word unigrams as features on the training data (SVM-Unigrams). This system is also included in the current analysis.\nMeasuring bias: To examine gender bias, we compared each system's predicted scores on the EEC sentence pairs as follows:\n\nThus, eleven pairs of scores (ten pairs of scores from ten noun phrase pairs and one pair of scores from the averages on name subsets) were examined for each template–emotion word instantiation. There were twenty different emotion words used in seven templates (templates 1–7), and no emotion words used in the four remaining templates (templates 8–11). In total, INLINEFORM0 pairs of scores were compared.\nSimilarly, to examine race bias, we compared pairs of system predicted scores as follows:\n\nThus, one pair of scores was examined for each template–emotion word instantiation. In total, INLINEFORM0 pairs of scores were compared.\nFor each system, we calculated the paired two sample t-test to determine whether the mean difference between the two sets of scores (across the two races and across the two genders) is significant. We set the significance level to 0.05. However, since we performed 438 assessments (219 submissions evaluated for biases in both gender and race), we applied Bonferroni correction. The null hypothesis that the true mean difference between the paired samples was zero was rejected if the calculated p-value fell below INLINEFORM0 .\nTwo test sets were provided for each task: 1. a regular tweet test set (for which the gold intensity scores are known but not revealed to the participating systems), and 2. the Equity Evaluation Corpus (for which no gold intensity labels exist).",

With her brother-in-law out of town, Lisa had agreed to watch her niece Stella for the afternoon and the little girl was known to be a bit of a handful. Her plan had been to spend the afternoon at the park to let Stella run and climb, to wear her out a bit.  Unfortunately, this outing was foiled by the constant downpour of rain so Lisa resigned herself to a day inside with the tiny tyrant. Stella arrived early and excited to play.  Lisa decided to begin with a game of hide and seek, after all this could take up a good part of the morning without too much trouble.  Stella ran off to hide and Lisa sat quietly drinking coffee while calling out to the little girl, pretending to seek. Eventually she set off to find the little girl but soon she realized that something was wrong.  No matter where she looked, Stella was nowhere to be found. The house wasn't that large, making her disappearance even more perplexing.  Lisa had only recently moved into the home that she bought from her great aunt shortly before her death and she hasn't even moved out all of the existing furniture. Maybe Stella had gotten stuck somewhere behind the large wardrobe in the bedroom or she had climbed up into a cupboard in the laundry room.  Panic was starting to settle in as she moved the wardrobe further from the wall, where only a small child could have hidden before.  Suddenly, saw a small crack in the wall, and then realized it was a small door that she never knew was there.  The door was slightly ajar and she eventually moved the wardrobe enough to open the door and climb inside. What was this place?  The entrance opened up to reveal a small room that Lisa never knew existed!  It was full of treasure, gold bars and jewels.  Stella sat in the middle of the room quietly playing with the treasure, unaware of the immense value she was surrounded by.  Lisa had known her aunt was a secretive woman but this was an incredible find and would change her life forever.  Stella's visit was the good luck charm she needed to unlock this bounty and she would be forever grateful to the little girl!  Time to call her brother-in-law to thank him for letting Stella visit.",

Average/std. bias: Average and standard deviation of the normalized estimation error (bias) of Q-functions Q ϕi. The error represents how significantly the Q-value estimate differs from the true one. Formally, the error is defined as\nwhere Q π (s, a) is the true Q-value under the current policy π and Q(s, a) is its estimate. In our experiment, Q π (s, a) was approximated by the discounted Monte Carlo return obtained with π in the test episodes. In addition, Q(s, a) was evaluated as\nfor SAC and REDQ and as for DroQ and DUVN, respectively. The comparison results (Figure) indicate that DroQ achieved almost the same level of performance as REDQ. Regarding the average return, REDQ and DroQ achieved almost the same sample efficiency overall. In Walker2d and Ant, their learning curves highly overlapped, and there was no significant difference between them. In Humanoid, REDQ was slightly better than DroQ. In Hopper, DroQ was better than REDQ. In all environments except Hopper, REDQ and DroQ improved their average return significantly earlier than SAC and DUVN. Regarding the bias, REDQ and DroQ consistently kept the value-estimation bias closer to zero than SAC and DUVN in all environments.\nDouble uncertainty value network (DUVN): Baseline method. This method is a DroQ variant that injects model uncertainty into a target in the same manner as the original DUVN (Moerland et al.,2017).",

        "answer": "These refer to two very large categories of wood species. Softwoods are generally fast-growing trees such as pine and fir commonly found throughout the world. They are most commonly used for construction and large volume projects as they are cheaper to produce and readily available, as the trees themselves do not take as long to grow. Hardwoods, on the other hand, are called \"hard\" because of much denser grains: compared to softwoods, hardwoods weigh more per volume due to this property. In other words, a board of walnut (a hardwood) weighs more than a board of the same size of pine (a softwood). They are more expensive because the trees take longer to grow and are typically more rare, but are used in fine wood-crafting arts like furniture making due to their robustness and beauty in the grain structure.",

        "evidence": "Asperger syndrome (AS), also known as Asperger's, is a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behaviour and interests. The syndrome is no longer recognised as a diagnosis in itself, having been merged with other conditions into autism spectrum disorder (ASD). It was considered to differ from other diagnoses that were merged into ASD by relatively unimpaired spoken language and intelligence.\n\nThe syndrome was named after the Austrian pediatrician Hans Asperger, who, in 1944, described children in his care who struggled to form friendships, did not understand others' gestures or feelings, engaged in one-sided conversations about their favourite interests, and were clumsy. In 1994, the diagnosis of Asperger's was included in the fourth edition (DSM-IV) of the American Diagnostic and Statistical Manual of Mental Disorders; however, with the publication of DSM-5 in 2013 the syndrome was removed, and the symptoms are now included within autism spectrum disorder along with classic autism and pervasive developmental disorder not otherwise specified (PDD-NOS). It was similarly merged into autism spectrum disorder in the International Classification of Diseases (ICD-11) as of 2021.\n\nThe exact cause of Asperger's is poorly understood. While it has high heritability, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role. Brain imaging has not identified a common underlying condition. There is no single treatment, and the UK's National Health Service (NHS) guidelines suggest that 'treatment' of any form of autism should not be a goal, since autism is not 'a disease that can be removed or cured'. According to the Royal College of Psychiatrists, while co-occurring conditions might require treatment, 'management of autism itself is chiefly about the provision of the education, training and social support/care required to improve the person's ability to function in the everyday world'. The effectiveness of particular interventions for autism is supported by only limited data. Interventions may include social skills training, cognitive behavioral therapy, physical therapy, speech therapy, parent training, and medications for associated problems, such as mood or anxiety. Autistic characteristics tend to become less obvious in adulthood, but social and communication difficulties usually persist.\n\nhttps://en.wikipedia.org/wiki/Asperger_syndrome",

        "evidence": "The NLP community is revisiting the role of linguistic structure in applications with the advent of contextual word representations (cwrs) derived from pretraining language models on large corpora BIBREF2, BIBREF3, BIBREF4, BIBREF5. Recent work has shown that downstream task performance may benefit from explicitly injecting a syntactic inductive bias into model architectures BIBREF6, even when cwrs are also used BIBREF7. However, high quality linguistic structure annotation at a large scale remains expensive—a trade-off needs to be made between the quality of the annotations and the computational expense of obtaining them. Shallow syntactic structures (BIBREF8; also called chunk sequences) offer a viable middle ground, by providing a flat, non-hierarchical approximation to phrase-syntactic trees (see Fig. FIGREF1 for an example). These structures can be obtained efficiently, and with high accuracy, using sequence labelers. In this paper we consider shallow syntax to be a proxy for linguistic structure.\nWhile shallow syntactic chunks are almost as ubiquitous as part-of-speech tags in standard NLP pipelines BIBREF9, their relative merits in the presence of cwrs remain unclear. We investigate the role of these structures using two methods. First, we enhance the ELMo architecture BIBREF0 to allow pretraining on predicted shallow syntactic parses, instead of just raw text, so that contextual embeddings make use of shallow syntactic context (§SECREF2). Our second method involves classical addition of chunk features to cwr-infused architectures for four different downstream tasks (§SECREF3). Shallow syntactic information is obtained automatically using a highly accurate model (97% $F_1$ on standard benchmarks). In both settings, we observe only modest gains on three of the four downstream tasks relative to ELMo-only baselines (§SECREF4).\nRecent work has probed the knowledge encoded in cwrs and found they capture a surprisingly large amount of syntax BIBREF10, BIBREF1, BIBREF11. We further examine the contextual embeddings obtained from the enhanced architecture and a shallow syntactic context, using black-box probes from BIBREF1. Our analysis indicates that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo embeddings (§SECREF18).\nOverall, our findings show that while shallow syntax can be somewhat useful, ELMo-style pretraining discovers representations which make additional awareness of shallow syntax largely redundant.\nOverall, our findings show that while shallow syntax can be somewhat useful, ELMo-style pretraining discovers representations which make additional awareness of shallow syntax largely redundant.",

Wikipedia articles are written according to the Media Wiki markup language, a HTML-like language. Among the structural elements of one page, which differs from standard HTML pages, there are i) the internal links, i.e., links to other Wikipedia pages, different from links to external resources); ii) categories, which represent the Media Wiki categories a page belongs to: they are encoded in the part of text within the Media Wiki “categories\" tag in the page source, and iii) informative boxes, so called “infoboxes\", which summarize in a structured manner some peculiar pieces of information related the topic of the article. The category values for the articles in the medical portal span over the ones listed at https://en.wikipedia.org/wiki/Portal:Medicine. Examples of categories, which appear at the bottom of each Wikipedia page, are in Fig. 1 .\nInfoboxes of the medical portal feature medical content and standard coding. As an example, Fig. 2 shows the infobox in the Alzheimer's disease page of the portal. The infobox contains explanatory figures and text denoting peculiar characteristics of the disease and the value for the standard code of such disease (ICD9, as for the international classification of the disease).\nThanks to WikiProject Medicine, the dataset of articles we collected from the Wikipedia Medicine Portal has been manually labeled into seven quality classes. They are ordered as Stub, Start, C, B, A, Good Article (GA), Featured Article (FA). The Featured and Good article classes are the highest ones: to have those labels, an article requires a community consensus and an official review by selected editors, while the other labels can be achieved with reviews from a larger, even controlled, set of editors. Actually, none of the articles in the dataset is labeled as A, thus, in the following, we do not consider that class, restricting the investigation to six classes.\nAt the date of our study, we were able to gather 24,362 rated documents. Remarkably, only a small percentage of them (1%) is labeled as GA and FA. Indeed, the distribution of the articles among the classes is highly skewed. There are very few (201) articles for the highest quality classes (FA and GA), while the vast majority (19,108) belongs to the lowest quality ones (Stub and Start). This holds not only for the medical portal. Indeed, it is common in all Wikipedia, where, on average, only one article in every thousand is a Featured one.\nIn Section \"Experiments and results\" , we will adopt a set of machine-learning classifiers to automatically label the articles into the quality classes. Dealing with imbalanced classes is a common situation in many real applications of classification learning: healthy patients over the population, fraudulent actions over daily genuine transactions, and so on. Without any countermeasure, common classifiers tend to correctly identify only articles belonging to the majority classes, clearly leading to severe mis-classification of the minority classes, since typical learning algorithms strive to maximize the overall prediction accuracy. To reduce the disequilibrium among the size of the classes, we have first randomly sampled the articles belonging to the most populated classes. Then, we have performed some further elaboration, as shown in the following.\nMany studies have been conducted to improve learning algorithms accuracy in presence of imbalanced data BIBREF8 . For the current work, we have considered one of the most popular approaches, namely the Synthetic Sampling with Data Generation, detailed in BIBREF9 . It consists in generating synthetic instances from the minority classes, to balance the overall dataset. The approach has been broadly applied to problems relying on NLP features, see, e.g., BIBREF10 . In our case, we resampled the input data set by applying the Synthetic Minority Oversampling TEchnique (SMOTE), with percentage 40% for GA and 180%, for FA. In particular, the steps to oversample are the following:\nTable 1 shows the number of articles in the dataset, divided per class, as well as the random samples we have considered for our study. The experiments presented in Section \"Experiments and results\" are based on the articles of the right-hand column in the table.\nWe consider the dataset consisting of the entire collection of articles of the Wikipedia Medicine Portal, updated at the end of 2014.",

The debate as to whether the nature (the intrinsic nature, the attitude, or the predisposition), or the nurture (the care, the teachings, or the conditioning) of a child is more responsible for who or what they become in adult life. \n\nLargely it is considered that humans are a product of context (Nurture). The situations in which we are raised have a considerable bearing on who we become in later life. But, it's not necessarily so black and white. There are countless examples of children having been born into extremely difficult circumstances, who have grown to be well rounded, high contributing members of society. \n\nAs a result, It would be reasonable to assume that Nature is a strong factor, regardless of the Nurture (the environment) in which a person is raised. After all, there's no guarantee that someone growing up in an abusive household will then abuse others themselves. So then is Nature more important? \n\nThe difficulty with the debate is that no one individual is the same as another. Experiments to establish the efficacy of Nature vs Nurture are difficult to perform. Not only from a human rights perspective, but additionally from a variable standpoint as well. Really there are far too many variables to control with regards to human nature, that any imposition of control on the Nurture element would be imbalanced. \n\nWhen considering this question, it's important to recognise that developmental psychology is still in its early stages, and to understand that both Nature AND Nurture are necessary factors in human development.",

In the United States, the concept is sometimes extended to refer to racial inequality in the United States. Minority women in white-majority countries often find the most difficulty in \"breaking the glass ceiling\" because they lie at the intersection of two historically marginalized groups: women and people of color.

This model, while rather crude, has shown that it can provide a clustering accurate enough to be used in topic identification of spoken document in unknown languages BIBREF2 . It was also shown that this model can be further improved by incorporating a Bayesian \"phonotactic\" language model learned jointly with the acoustic units BIBREF3 .

Joty et al. BIBREF22 apply divisive clustering instead of thresholding for segmentation. Malioutov et al. BIBREF23 formalize segmentation as a graph-partitioning problem and propose a minimum cut model based on tf INLINEFORM0 idf features to segment lectures. Ye et al. BIBREF24 minimize between-segment similarity while maximizing within-segment similarity. However, the above complicated approaches are known as global methods: when we perform segmentation between two successive sentences, future context information is needed. Therefore, they are inapplicable to real-time chat-bots, where conversation utterances can be viewed as streaming data.\nIn our study, we prefer the simple yet effective TextTiling approach for open-domain dialogue session segmentation, but enhance it with modern advances of word embeddings, which are robust in capturing semantics of words.

        "answer": "All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention.",
        "evidence": "The used architecture of the QA model is briefly summarized below. Here we choose QANet BIBREF2 as the base model due to the following reasons: 1) it achieves the second best performance on SQuAD, and 2) since there are completely no recurrent networks in QANet, its training speed is 5x faster than BiDAF BIBREF17 when reaching the same performance on SQuAD.\nThe network architecture is illustrated in Figure FIGREF2 . The left blocks and the right blocks form two QANets, each of which takes a document and a question as the input and outputs an answer. In QANet, firstly, an embedding encoder obtains word and character embeddings for each word in INLINEFORM0 or INLINEFORM1 and then models the temporal interactions between words and refines word vectors to contextualized word representations. All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention. The intuition here is that convolution components can model local interactions and self-attention components focus on modeling global interactions. The context-query attention layer generates the question-document similarity matrix and computes the question-aware vector representations of the context words. After that, a model encoder layer containing seven encoder blocks captures the interactions among the context words conditioned on the question. Finally, the output layer predicts a start position and an end position in the document to extract the answer span from the document.\nAll encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention.",

        "question": "Linking between what is established by their new system?",
        "answer": "Princeton WordNet and DBpedia.",
        "evidence": "Princeton WordNet BIBREF0 is one of the most important resources used in many different tasks across linguistics and natural language processing, however the resource is only available for English and is limited in its coverage of real world concepts. To cross the language barrier, huge efforts have been made to extend the Princeton WordNet with multilingual information in projects, such as EuroWordNet BIBREF1 , BalkaNet BIBREF2 and MultiWordNet BIBREF3 , mostly following the extend approach, where the structure of the Princeton WordNet is preserved and only the words in each synset are translated and new synsets are added for concepts. Furthermore, the Princeton WordNet has many fewer concepts than large scale encyclopedias such as Wikipedia and resources derived from it such as DBpedia BIBREF4 and BabelNet BIBREF5 . This problem is even worse for many non-English wordnets, due to the extend approach, as these resources have even fewer synsets than Princeton WordNet. Furthermore, there are still many languages for which a wordnet does not exist or is not available to all potential users due to licensing restrictions.\nTo address these deficiencies we propose two approaches. Firstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages. While an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries. In addition, our method can handle fundamental complexities such as the need to translate all senses of a word including low-frequency senses, which is very challenging for current SMT approaches. For these reasons, we leverage existing translations of Princeton WordNet entries in other languages to identify contextual information for wordnet senses from a large set of generic parallel corpora. The goal is to identify sentences that share the same semantic information in respect to the synset of the Princeton WordNet entry that we want to translate. Secondly, we describe a novel system based on state-of-the-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia. This method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks. These statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph. These are combined using a constraint-based solver that considers not only the semantic similarity of the synsets but also the overall structure of the alignment and its consistency, following the best practices in ontology alignment.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet BIBREF6 , which is available under an open (CC-BY) license. Finally, we describe how this resource is published, firstly as linked data in the linguistic linked open data cloud, as well as published in all the formats of the Global WordNet Association Interlingual Index.\nSecondly, we describe a novel system based on state-ofthe-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia.",

On the street’s southern side, the street intersects with (from east to west), Herbert-von-Karajan-Straße, Stauffenbergstraße, Hildebrandstraße, Hiroshimastraße and Clara-Wieck-Straße.The neighbourhood was incorporated into the City of Berlin in 1861, soon after the 1871 Unification of Germany it developed into an affluent residential area and later into the capital's diplomatic quarter.The Kemperplatz at the eastern end formerly marked the starting point of the Siegesallee boulevard running northwards through the park to Königsplatz in front of the Reichstag. On Tiergartenstaße No. 1 is the Berlin Musical Instrument Museum and the adjacent building of the Berliner Philharmonie behind it, a major centre for musical performances.On the western corner on Tiergartenstraße No. 6 is the Berlin Museum of Applied Art and next to it the Berlin Art Library, both part of the Kulturforum cluster of the Berlin State Museums. On the intersection with Stauffenbergstraße on No. 12 is the Austrian embassy, erected in 2001 according to plans designed by Hans Hollein. Further diplomatic missions follow: the Indian and South African embassies (on No. 18) as well as the Italian and Japanese representations at the corner of Hiroshimastraße, both as former Axis powers located at vast buildings from about 1941/42 that have been reconstructed after World War II. A number of other embassies are located along nearby streets.At the western end of Tiergartenstraße are the Jesuit Canisius-Kolleg gymnasium in the building of the former Krupp representative office on No. 30, the Saudi Arabian embassy and finally the offices of the Christian Democratic Konrad Adenauer Foundation. On the corner of Klingelhöferstraße is a sculpture depicting Konrad Adenauer and Charles de Gaulle shaking hands, symbolising their role in overcoming the centuries-long French–German enmity and laying the groundwork for the Franco–German Friendship after World War II.On the north side of Tiergartenstraße just west of Stauffenbergstraße is a large seated statue of the composer Richard Wagner in the Tiergarten park.

        "answer": "1,270 conversation.",
        "evidence": "\nWe consider two datasets, representing related but slightly different forecasting tasks. The first dataset is an expanded version of the annotated Wikipedia conversations dataset from BIBREF9. This dataset uses carefully-controlled crowdsourced labels, strictly filtered to ensure the conversations are civil up to the moment of a personal attack. This is a useful property for the purposes of model analysis, and hence we focus on this as our primary dataset. However, we are conscious of the possibility that these strict labels may not fully capture the kind of behavior that moderators care about in practice. We therefore introduce a secondary dataset, constructed from the subreddit ChangeMyView (CMV) that does not use post-hoc annotations. Instead, the prediction task is to forecast whether the conversation will be subject to moderator action in the future.\nWikipedia data. BIBREF9's `Conversations Gone Awry' dataset consists of 1,270 conversations that took place between Wikipedia editors on publicly accessible talk pages. The conversations are sourced from the WikiConv dataset BIBREF59 and labeled by crowdworkers as either containing a personal attack from within (i.e., hostile behavior by one user in the conversation directed towards another) or remaining civil throughout.\nA series of controls are implemented to prevent models from picking up on trivial correlations. To prevent models from capturing topic-specific information (e.g., political conversations are more likely to derail), each attack-containing conversation is paired with a clean conversation from the same talk page, where the talk page serves as a proxy for topic. To force models to actually capture conversational dynamics rather than detecting already-existing toxicity, human annotations are used to ensure that all comments preceding a personal attack are civil.\nTo the ends of more effective model training, we elected to expand the `Conversations Gone Awry' dataset, using the original annotation procedure. Since we found that the original data skewed towards shorter conversations, we focused this crowdsourcing run on longer conversations: ones with 4 or more comments preceding the attack. Through this additional crowdsourcing, we expand the dataset to 4,188 conversations, which we are publicly releasing as part of the Cornell Conversational Analysis Toolkit (ConvoKit).\nWe perform an 80-20-20 train/dev/test split, ensuring that paired conversations end up in the same split in order to preserve the topic control. Finally, we randomly sample another 1 million conversations from WikiConv to use for the unsupervised pre-training of the generative component.\nReddit CMV data. The CMV dataset is constructed from conversations collected via the Reddit API. In contrast to the Wikipedia-based dataset, we explicitly avoid the use of post-hoc annotation. Instead, we use as our label whether a conversation eventually had a comment removed by a moderator for violation of Rule 2: “Don't be rude or hostile to other users”.\nThough the lack of post-hoc annotation limits the degree to which we can impose controls on the data (e.g., some conversations may contain toxic comments not flagged by the moderators) we do reproduce as many of the Wikipedia data's controls as we can. Namely, we replicate the topic control pairing by choosing pairs of positive and negative examples that belong to the same top-level post, following BIBREF12; and enforce that the removed comment was made by a user who was previously involved in the conversation. This process results in 6,842 conversations, to which we again apply a pair-preserving 80-20-20 split. Finally, we gather over 600,000 conversations that do not include any removed comment, for unsupervised pre-training.\nWikipedia data.

Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension. Finally, morales-EtAl:2016:EMNLP2016 provided InfoboxQA for answer selection.\nThese corpora make it possible to evaluate the robustness of statistical question answering learning. Although all of these corpora target on selection-based QA, they are designed for different purposes such that it is important to understand the nature of these corpora so a better use of them can be made.

SelQA and SQuAD show similar average question lengths ( INLINEFORM1 ) because of the similarity between their annotation schemes. It is not surprising that WikiQA's average question length is the smallest, considering their questions are taken from search queries. InfoboxQA's average question length is relatively small, due to the restricted information that can be asked from the infoboxes.

        "evidence": "Neural machine translation has recently achieved impressive results BIBREF0 , BIBREF1 , while learning from raw, sentence-aligned parallel text and using little in the way of external linguistic information. However, we hypothesize that various levels of linguistic annotation can be valuable for neural machine translation. Lemmatisation can reduce data sparseness, and allow inflectional variants of the same word to explicitly share a representation in the model. Other types of annotation, such as parts-of-speech (POS) or syntactic dependency labels, can help in disambiguation. In this paper we investigate whether linguistic information is beneficial to neural translation models, or whether their strong learning capability makes explicit linguistic features redundant.\nLet us motivate the use of linguistic features using examples of actual translation errors by neural MT systems. In translation out of English, one problem is that the same surface word form may be shared between several word types, due to homonymy or word formation processes such as conversion. For instance, close can be a verb, adjective, or noun, and these different meanings often have distinct translations into other languages. Consider the following English INLINEFORM0 German example:\nFor the English source sentence in Example SECREF4 (our translation in Example SECREF5 ), a neural MT system (our baseline system from Section SECREF4 ) mistranslates close as a verb, and produces the German verb schließen (Example SECREF6 ), even though close is an adjective in this sentence, which has the German translation nah. Intuitively, part-of-speech annotation of the English input could disambiguate between verb, noun, and adjective meanings of close.\nAs a second example, consider the following German INLINEFORM0 English example:\nGerman main clauses have a verb-second (V2) word order, whereas English word order is generally SVO. The German sentence (Example UID7 ; English reference in Example UID8 ) topicalizes the predicate gefährlich 'dangerous', putting the subject die Route 'the route' after the verb. Our baseline system (Example UID9 ) retains the original word order, which is highly unusual in English, especially for prose in the news domain. A syntactic annotation of the source sentence could support the attentional encoder-decoder in learning which words in the German source to attend (and translate) first.\nWe will investigate the usefulness of linguistic features for the language pair German INLINEFORM0 English, considering the following linguistic features:\nThe inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form. The other linguistic features are motivated by disambiguation, as discussed in our introductory examples.\nWe will investigate the usefulness of linguistic features for the language pair German↔English, considering the following linguistic features: The inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form.",

        "evidence": "We present our results for the binary classification tasks in Tables TABREF23 – TABREF24 in terms of average precision, average recall and macro average F1 score. The results of the regression tasks are reported in Tables TABREF25 and TABREF29 in terms of the mean absolute error between the predicted and actual scores, as well as the Spearman INLINEFORM0 correlation between the rankings induced by both sets of scores. It can be clearly seen from the results that our proposed method (EGEL-All) can effectively integrate Flickr tags with the available structured information. It outperforms the baselines for all the considered tasks. Furthermore, note that the PPMI-based weighting in EGEL-Tags consistently outperforms GloVe and that both the addition of negative examples and term selection lead to further improvements. The use of term selection leads to particularly substantial improvements for the regression problems.\nWhile our experimental results confirm the usefulness of embeddings for predicting environmental features, this is only consistently the case for the variants that use both the tags and the structured datasets. In particular, comparing BOW-Tags with EGEL-Tags, we sometimes see that the former achieves the best results. While this might seem surprising, it is in accordance with the findings in BIBREF54 , BIBREF38 , among others, where it was also found that bag-of-words representations can sometimes lead to surprisingly effective baselines. Interestingly, we note that in all cases where EGEL-KL(Tags+NS) performs worse than BOW-Tags, we also find that BOW-KL(Tags) performs worse than BOW-Tags. This suggests that for these tasks there is a very large variation in the kind of tags that can inform the prediction model, possibly including e.g. user-specific tags. Some of the information captured by such highly specific but rare tags is likely to be lost in the embedding.\nTo further analyze the difference in performance between BoW representations and embeddings, Figure TABREF29 compares the performance of the GloVe model with the bag-of-words model for predicting place scenicness, as a function of the number of tag occurrences at the considered locations. What is clearly noticeable in Figure TABREF29 is that GloVe performs better than the bag-of-words model for large corpora and worse for smaller corpora.

        "question": "What is their work inspired by?",
        "answer": "By the goal of assisting human moderators of online communities by preemptively signaling at-risk conversations that might deserve their attention.",
        "evidence": "“Ché saetta previsa vien più lenta.”\n\n– Dante Alighieri, Divina Commedia, Paradiso\nAntisocial behavior is a persistent problem plaguing online conversation platforms; it is both widespread BIBREF0 and potentially damaging to mental and emotional health BIBREF1, BIBREF2. The strain this phenomenon puts on community maintainers has sparked recent interest in computational approaches for assisting human moderators.\nPrior work in this direction has largely focused on post-hoc identification of various kinds of antisocial behavior, including hate speech BIBREF3, BIBREF4, harassment BIBREF5, personal attacks BIBREF6, and general toxicity BIBREF7. The fact that these approaches only identify antisocial content after the fact limits their practicality as tools for assisting pre-emptive moderation in conversational domains.\nAddressing this limitation requires forecasting the future derailment of a conversation based on early warning signs, giving the moderators time to potentially intervene before any harm is done (BIBREF8 BIBREF8, BIBREF9 BIBREF9, see BIBREF10 BIBREF10 for a discussion). Such a goal recognizes derailment as emerging from the development of the conversation, and belongs to the broader area of conversational forecasting, which includes future-prediction tasks such as predicting the eventual length of a conversation BIBREF11, whether a persuasion attempt will eventually succeed BIBREF12, BIBREF13, BIBREF14, whether team discussions will eventually lead to an increase in performance BIBREF15, or whether ongoing counseling conversations will eventually be perceived as helpful BIBREF16.\nApproaching such conversational forecasting problems, however, requires overcoming several inherent modeling challenges. First, conversations are dynamic and their outcome might depend on how subsequent comments interact with each other. Consider the example in Figure FIGREF2: while no individual comment is outright offensive, a human reader can sense a tension emerging from their succession (e.g., dismissive answers to repeated questioning). Thus a forecasting model needs to capture not only the content of each individual comment, but also the relations between comments. Previous work has largely relied on hand-crafted features to capture such relations—e.g., similarity between comments BIBREF16, BIBREF12 or conversation structure BIBREF17, BIBREF18—, though neural attention architectures have also recently shown promise BIBREF19.\nThe second modeling challenge stems from the fact that conversations have an unknown horizon: they can be of varying lengths, and the to-be-forecasted event can occur at any time. So when is it a good time to make a forecast? Prior work has largely proposed two solutions, both resulting in important practical limitations. One solution is to assume (unrealistic) prior knowledge of when the to-be-forecasted event takes place and extract features up to that point BIBREF20, BIBREF8. Another compromising solution is to extract features from a fixed-length window, often at the start of the conversation BIBREF21, BIBREF15, BIBREF16, BIBREF9. Choosing a catch-all window-size is however impractical: short windows will miss information in comments they do not encompass (e.g., a window of only two comments would miss the chain of repeated questioning in comments 3 through 6 of Figure FIGREF2), while longer windows risk missing the to-be-forecasted event altogether if it occurs before the end of the window, which would prevent early detection.\nIn this work we introduce a model for forecasting conversational events that overcomes both these inherent challenges by processing comments, and their relations, as they happen (i.e., in an online fashion). Our main insight is that models with these properties already exist, albeit geared toward generation rather than prediction: recent work in context-aware dialog generation (or “chatbots”) has proposed sequential neural models that make effective use of the intra-conversational dynamics BIBREF22, BIBREF23, BIBREF24, while concomitantly being able to process the conversation as it develops (see BIBREF25 for a survey).\nIn order for these systems to perform well in the generative domain they need to be trained on massive amounts of (unlabeled) conversational data. The main difficulty in directly adapting these models to the supervised domain of conversational forecasting is the relative scarcity of labeled data: for most forecasting tasks, at most a few thousands labeled examples are available, insufficient for the notoriously data-hungry sequential neural models.\nTo overcome this difficulty, we propose to decouple the objective of learning a neural representation of conversational dynamics from the objective of predicting future events. The former can be pre-trained on large amounts of unsupervised data, similarly to how chatbots are trained. The latter can piggy-back on the resulting representation after fine-tuning it for classification using relatively small labeled data. While similar pre-train-then-fine-tune approaches have recently achieved state-of-the-art performance in a number of NLP tasks—including natural language inference, question answering, and commonsense reasoning (discussed in Section SECREF2)—to the best of our knowledge this is the first attempt at applying this paradigm to conversational forecasting.\nTo test the effectiveness of this new architecture in forecasting derailment of online conversations, we develop and distribute two new datasets. The first triples in size the highly curated `Conversations Gone Awry' dataset BIBREF9, where civil-starting Wikipedia Talk Page conversations are crowd-labeled according to whether they eventually lead to personal attacks; the second relies on in-the-wild moderation of the popular subreddit ChangeMyView, where the aim is to forecast whether a discussion will later be subject to moderator action due to “rude or hostile” behavior. In both datasets, our model outperforms existing fixed-window approaches, as well as simpler sequential baselines that cannot account for inter-comment relations. Furthermore, by virtue of its online processing of the conversation, our system can provide substantial prior notice of upcoming derailment, triggering on average 3 comments (or 3 hours) before an overtly toxic comment is posted.\nTo summarize, in this work we:\nintroduce the first model for forecasting conversational events that can capture the dynamics of a conversation as it develops;\nbuild two diverse datasets (one entirely new, one extending prior work) for the task of forecasting derailment of online conversations;\ncompare the performance of our model against the current state-of-the-art, and evaluate its ability to provide early warning signs.\nOur work is motivated by the goal of assisting human moderators of online communities by preemptively signaling at-risk conversations that might deserve their attention. However, we caution that any automated systems might encode or even amplify the biases existing in the training data BIBREF26, BIBREF27, BIBREF28, so a public-facing implementation would need to be exhaustively scrutinized for such biases BIBREF29.\n\nOur work is motivated by the goal of assisting human moderators of online communities by preemptively signaling at-risk conversations that might deserve their attention.",

        "evidence": "Microblogging platforms such as Twitter are increasingly being used in event detection. Existing approaches mainly use machine learning models and rely on event-related keywords to collect the data for model training. These approaches make strong assumptions on the distribution of the relevant micro-posts containing the keyword -- referred to as the expectation of the distribution -- and use it as a posterior regularization parameter during model training. Such approaches are, however, limited as they fail to reliably estimate the informativeness of a keyword and its expectation for model training. This paper introduces a Human-AI loop approach to jointly discover informative keywords for model training while estimating their expectation. Our approach iteratively leverages the crowd to estimate both keyword specific expectation and the disagreement between the crowd and the model in order to discover new keywords that are most beneficial for model training. These keywords and their expectation not only improve the resulting performance but also make the model training process more transparent. We empirically demonstrate the merits of our approach, both in terms of accuracy and interpretability, on multiple real-world datasets and show that our approach improves the state of the art by 24.3%.\nSuch approaches are, however, limited as they fail to reliably estimate the informativeness of a keyword and its expectation for model training.",

        "answer": "A discrete similarity score between predicted and target summaries based on 1-gram, 2-gram, and n-gram overlap.",
        "evidence": "When there are a very large number of documents that need to be read in limited time, we often resort to reading summaries instead of the whole document. Automatically generating (abstractive) summaries is a problem with various applications, e.g., automatic authoring BIBREF0. We have developed automatic text summarization systems that condense large documents into short and readable summaries. It can be used for both single (e.g., BIBREF1, BIBREF2 and BIBREF3) and multi-document summarization (e.g.,BIBREF4, BIBREF3, BIBREF5).\nText summarization is broadly classified into two categories: extractive (e.g., BIBREF3 and BIBREF6) and abstractive summarization (e.g., BIBREF7, BIBREF8 and BIBREF9). Extractive approaches select sentences from a given document and groups them to form concise summaries. By contrast, abstractive approaches generate human-readable summaries that primarily capture the semantics of input documents and contain rephrased key content. The former task falls under the classification paradigm, and the latter belongs to the generative modeling paradigm, and therefore, it is a much harder problem to solve. The backbone of state-of-the-art summarization models is a typical encoder-decoder BIBREF10 architecture that has proved to be effective for various sequential modeling tasks such as machine translation, sentiment analysis, and natural language generation. It contains an encoder that maps the raw input word vector representations to a latent vector. Then, the decoder usually equipped with a variant of the attention mechanism BIBREF11 uses the latent vectors to generate the output sequence, which is the summary in our case. These models are trained in a supervised learning setting where we minimize the cross-entropy loss between the predicted and the target summary. Encoder-decoder models have proved effective for short sequence tasks such as machine translation where the length of a sequence is less than 120 tokens. However, in text summarization, the length of the sequences vary from 400 to 800 tokens, and modeling long-term dependencies becomes increasingly difficult.\nDespite the metric's known drawbacks, text summarization models are evaluated using ROUGE BIBREF12, a discrete similarity score between predicted and target summaries based on 1-gram, 2-gram, and n-gram overlap. Cross-entropy loss would be a convenient objective on which to train the model since ROUGE is not differentiable, but doing so would create a mismatch between metrics used for training and evaluation. Though a particular summary scores well on ROUGE evaluation comparable to the target summary, it will be assigned lower probability by a supervised model. To tackle this problem, we have used a self-critic policy gradient method BIBREF13 to train the models directly using the ROUGE score as a reward. In this paper, we propose an architecture that addresses the issues discussed above.\nDespite the metric’s known drawbacks, text summarization models are evaluated using ROUGE (Lin, 2004), a discrete similarity score between predicted and target summaries based on 1-gram, 2-gram, and n-gram overlap.",

If the language of a piece of text is known then the appropriate downstream models like parts of speech taggers and language models can be applied as required.\nLID is further also an important step in harvesting scarce language resources. Harvested data can be used to bootstrap more accurate LID models and in doing so continually improve the quality of the harvested data. Availability of data is still one of the big roadblocks for applying data driven approaches like supervised machine learning in developing countries.\nHaving 11 official languages of South Africa has lead to initiatives (discussed in the next section) that have had positive effect on the availability of language resources for research. However, many of the South African languages are still under resourced from the point of view of building data driven models for machine comprehension and process automation.\nTable TABREF2 shows the percentages of first language speakers for each of the official languages of South Africa. These are four conjunctively written Nguni languages (zul, xho, nbl, ssw), Afrikaans (afr) and English (eng), three disjunctively written Sotho languages (nso, sot, tsn), as well as tshiVenda (ven) and Xitsonga (tso). The Nguni languages are similar to each other and harder to distinguish. The same is true of the Sotho languages.\nThis paper presents a hierarchical naive Bayesian and lexicon based classifier for LID of short pieces of text of 15-20 characters long.

        "answer": "Uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times.",
        "evidence": "For evaluating topics with automatic quality measures, we used several English text collections and one Russian collection (Table TABREF7 ). We experiment with three thesauri: WordNet (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms), and Russian thesaurus RuThes (115 thousand entries) BIBREF19 .\nAt the preprocessing step, documents were processed by morphological analyzers. Also, we extracted noun groups as described in BIBREF16 . As baselines, we use the unigram LDA topic model and LDA topic model with added 1000 ngrams with maximal NC-value BIBREF20 extracted from the collection under analysis.\nAs it was found before BIBREF14 , BIBREF16 , the addition of ngrams without accounting relations between their components considerably worsens the perplexity because of the vocabulary growth (for perplexity the less is the better) and practically does not change other automatic quality measures (Table 2).\nWe add the Wordnet data in the following steps. At the first step, we include WordNet synonyms (including multiword expressions) into the proposed similarity sets (LDA-Sim+WNsyn). At this step, frequencies of synonyms found in the same document are summed up in process LDA topic learning as described in Algorithm SECREF3 . We can see that the kernel uniqueness becomes very low, topics are very close to each other in content (Table 2: LDA-Sim+WNsyn). At the second step, we add word direct relatives (hyponyms, hypernyms, etc.) to similarity sets. Now the frequencies of semantically related words are added up enhancing the contribution into all topics of the current document.\nThe Table 2 shows that these two steps lead to great degradation of the topic model in most measures in comparison to the initial unigram model: uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times (Table 2: LDA-Sim+WNsynrel). It is evident that at this step the model has a poor quality. When we look at the topics, the cause of the problem seems to be clear. We can see the overgeneralization of the obtained topics. The topics are built around very general words such as \"person\", \"organization\", \"year\", etc. These words were initially frequent in the collection and then received additional frequencies from their frequent synonyms and related words.\nThen we suppose that these general words were used in texts to discuss specific events and objects, therefore, we change the constructions of the similarity sets in the following way: we do not add word hyponyms to its similarity set. Thus, hyponyms, which are usually more specific and concrete, should obtain additional frequencies from upper synsets and increase their contributions into the document topics. But the frequencies and contribution of hypernyms into the topic of the document are not changed. And we see the great improvement of the model quality: the kernel uniqueness considerably improves, perplexity decreases to levels comparable with the unigram model, topic coherence characteristics also improve for most collections (Table 2:LDA-Sim+WNsynrel/hyp).\nWe further use the WordNet-based similarity sets with n-grams having the same components as described in BIBREF16 . All measures significantly improve for all collections (Table 2:LDA-Sim+WNsr/hyp+Ngrams). At the last step, we try to apply the same approach to ngrams that was previously utilized to hyponym-hypernym relations: frequencies of shorter ngrams and words are summed to frequencies of longer ngrams but not vice versa. In this case we try to increase the contribution of more specific longer ngrams into topics. It can be seen (Table 2) that the kernel uniqueness grows significantly, at this step it is 1.3-1.6 times greater than for the baseline models achieving 0.76 on the ACL collection (Table 2:LDA-Sim+WNsr/hyp+Ngrams/l).\nAt the second series of the experiments, we applied EuroVoc information retrieval thesaurus to two European Union collections: Europarl and JRC. In content, the EuroVoc thesaurus is much smaller than WordNet, it contains terms from economic and political domains and does not include general abstract words. The results are shown in Table 3. It can be seen that inclusion of EuroVoc synsets improves the topic coherence and increases kernel uniqueness (in contrast to results with WordNet). Adding ngrams further improves the topic coherence and kernel uniqueness.\nAt last we experimented with the Russian banking collection and utilized RuThes thesaurus. In this case we obtained improvement already on RuThes synsets and again adding ngrams further improved topic coherence and kernel uniqueness (Table 4).\nIt is worth noting that adding ngrams sometimes worsens the TC-NPMI measure, especially on the JRC collection. This is due to the fact that in these evaluation frameworks, the topics' top elements contain a lot of multiword expressions, which rarely occur in Wikipedia, used for the coherence calculation, therefore the utilized automatic coherence measures can have insufficient evidence for correct estimates.\nThe Table 2 shows that these two steps lead to great degradation of the topic model in most measures in comparison to the initial unigram model: uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times (Table 2: LDASim+WNsynrel).",

For example, in turn right on the first intersection, the instruction needs to be interpreted, and a specific object in the world (the intersection) needs to be located in order to execute the instruction. In NL navigation studies, the representation of the world may be provided via visual sensors BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4 or as a symbolic world representation. This work focuses on navigation based on a symbolic world representation (referred to as a map).\nPrevious datasets for NL navigation based on a symbolic world representation, HCRC BIBREF5, BIBREF6, BIBREF7 and SAIL BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15 present relatively simple worlds, with a small fixed set of entities known to the navigator in advance. Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes.

First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nUsing Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers.",

        "evidence": "",
        "answer": "Saving for retirement is an important topic for any individual or family to consider. \n\nIn the US, most full-time employees are eligible for 401K or Roth IRA retirement savings programs through their employer, which enable you to defer taxes on your income and, in some cases, receive additional supplemental contributions up to a certain amount from your employer.\n\nThrough your 401K you often have access to a select range of what are call index funds, or mixes of securities that track specific groups of stocks, bonds, or other financial instruments. These can be actively managed, where a company or advisor controls the underlying investments in these funds, or passively managed, where the fund tracks a specific market or list of companies (example: XLF, a fund that tracks the broader banking industry). \n\nIn terms of managing risk, generally you have a higher percentage of stocks vs. bonds or cash in your portfolio earlier in your career, with this mix shifting toward lower risk bonds as you get closer to retirement. Generally speaking, while actively managed funds do in some instances perform well, they are, on average, very similar in their performance to passively managed index funds and, due to their associated fees, most experts agree it's wise to focus on broad market index funds. \n\nA common retirement portfolio for a 30 year old might be comprised 50-75% of large capitalization domestic stock funds. It's typically wise to have some exposure to foreign markets and small/medium capitalization domestic stocks or specific market segments, with minimal bonds or cash until later in life.",

Other common features include unusual responses to sensory stimuli and a preference for sameness or unusual adherence to routines.\nAutism is generally understood to be a spectrum disorder, as it can manifest differently in each person: any autistic individual is likely to show some, but not all, of the characteristics associated with it, and the person may exhibit them to varying degrees and frequencies.There is large variation in the support needs of autistic people, and some are nonspeaking, while others have proficient spoken language.",

Others have relatively low support needs; they may have more typical speech-language and intellectual skills but atypical social/conversation skills, narrowly focused interests, and wordy, pedantic communication.They may still require significant support in some areas of their lives.

        "question": "Whether there is no query-bag matching study existed before their study?",
        "answer": "Yes.",
        "evidence": "AliMe Bot is a kind of retrieval-based online service of E-commerce which collects a lot of predefined question-answering pairs. Through data analysis, we find that many variants of a question exist which means a sort of questions can correspond to a same answer. Based on the observation, naturally, we can view these questions with the same answer as a bag. Obviously, the bag contains diverse expressions of a question, which may provide more matching evidence than only one question due to the rich information contained in the bag. Motivated by the fact, different from existing query-question (Q-Q) matching method, we propose a new query-bag matching approach for retrieval-based chatbots. Concretely, when a user raises a query, the query-bag matching model provides the most suitable bag and returns the corresponding answer of the bag. To our knowledge, there is no query-bag matching study exists, and we focus on the new approach in this paper.\nRecalling the text matching task BIBREF0, recently, researchers have adopted the deep neural network to model the matching relationship. ESIM BIBREF1 judges the inference relationship between two sentences by enhanced LSTM and interaction space. SMN BIBREF2 performs the context-response matching for the open-domain dialog system. BIBREF3 BIBREF3 explores the usefulness of noisy pre-training in the paraphrase identification task. BIBREF4 BIBREF4 surveys the methods in query-document matching in web search which focuses on the topic model, the dependency model, etc. However, none of them pays attention to the query-bag matching which concentrates on the matching for a query and a bag containing multiple questions.\nWhen a user poses a query to the bot, the bot searches the most similar bag and uses the corresponding answer to reply to the user. The more information in the query covered by the bag, the more likely the bag's corresponding answer answers the query. What's more, the bag should not have too much information exceeding the query. Thus modelling the bag-to-query and query-to-bag coverage is essential in this task.\nIn this paper, we propose a simple but effective mutual coverage component to model the above-mentioned problem. The coverage is based on the cross-attention matrix of the query-bag pair which indicates the matching degree of elements between the query and bag. The mutual coverage is performed by stacking the cross-attention matrix along two directions, i.e., query and bag, in the word level respectively. In addition to the mutual coverage, a bag representation in word level is issued to help discover the main points of a bag. The bag representation then provides new matching evidence to the query-bag matching model.\nWe conduct experiments on the AliMe and Quora dataset for the query-bag matching based information-seeking conversation. Compared with baselines, we verify the effectiveness of our model. Our model obtains 0.05 and 0.03 $\\text{R}_{10}@1$ gains comparing to the strongest baseline in the two datasets. The ablation study shows the usefulness of the components. The contributions in this paper are summarized as follows: 1) To the best of our knowledge, we are the first to adopt query-bag matching in the information-seeking conversation. 2) We propose the mutual coverage model to measure the information coverage in the query-bag matching. 3) We release the composite Quora dataset to facilitate the research in this area.\nTo our knowledge, there is no query-bag matching study exists, and we focus on the new approach in this paper",

The upper part of the combined plant is called the scion (/ˈsaɪən/) while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together and such joining is called inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades.\n\nIn most cases, one plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion or cion. The scion contains the desired genes to be duplicated in future production by the stock/scion plant.\n\nIn stem grafting, a common grafting method, a shoot of a selected, desired plant cultivar is grafted onto the stock of another type. In another common form called bud grafting, a dormant side bud is grafted onto the stem of another stock plant, and when it has inosculated successfully, it is encouraged to grow by pruning off the stem of the stock plant just above the newly grafted bud.\n\nFor successful grafting to take place, the vascular cambium tissues of the stock and scion plants must be placed in contact with each other. Both tissues must be kept alive until the graft has \"taken\", usually a period of a few weeks. Successful grafting only requires that a vascular connection take place between the grafted tissues. Research conducted in Arabidopsis thaliana hypocotyls has shown that the connection of phloem takes place after three days of initial grafting, whereas the connection of xylem can take up to seven days. Joints formed by grafting are not as strong as naturally formed joints, so a physical weak point often still occurs at the graft because only the newly formed tissues inosculate with each other.

Our model complexity does not increase when the number of slots in dialogue tasks go up. Thus, SIM has many fewer parameters than existing dialogue state tracking models. To compensate for the exclusion of slot-specific parameters, we incorporate better feature representation of user utterance and dialogue states using syntactic information and convolutional neural networks (CNN). The refined representation, in addition to cross and self-attention mechanisms, make our model achieve even better performance than slot-specific models. For instance, on Wizard-of-Oz (WOZ) 2.0 dataset BIBREF8, the SIM model obtains a joint-accuracy score of 89.5%, 1.4% higher than the previously best model GLAD, with only 22% of the number of parameters. On DSTC2 dataset, SIM achieves comparable performance with previous best models with only 19% of the model size.\n To compensate for the exclusion of slot-specific parameters, we incorporate better feature representation of user utterance and dialogue states using syntactic information and convolutional neural networks (CNN).",

Since she also enjoyed camping, she decided to go deep into the forest during a long weekend to complete her assignment. \n\nAs she got deeper into the forest, away from civilization, the tree cover became thicker, and therefore the floor of the forest became darker. \"Perfect for fungi growth!\" she thought. She started seeing more and more fungi, some on the trees, some on rotting logs, and some on the forest floor. Peculiarly, most of the fungi she began to see as she got deeper in the forest were green, which was quite unusual.\n\nShe catalogued all the fungi she saw for the next several days. On her way out, she took the same path she came in on, but noticed that the fungi along her path had changed to possess typical colors of fungi, not the green she had seen when she came in. She explored perpendicular to her path, and found a slowly changing range of colors, until she saw the same green she had seen when she came in.\n\nShe needed to return to school, but decided to come back the next weekend.\n\nWhen she arrived back into the fungi's domain, she saw something breathtaking as she explored. Everywhere she had gone, a ripple of colors seemed to have formed. The fungi had reacted to her presence, and sent signals to the other fungi in the area, where the signal had been propagated. Some of the fungi on her original path had even returned to the original green color she had observed upon entering the forest. She also noticed the local fauna completely avoided the areas where the fungi had changed from its original green color.

        "answer": "The positions of the objects and their co-occurrences are encoded in the information given to the agent (i.e. the fact that an oven is in a kitchen). What is missing is just the visual appearance of the scenes.",
        "evidence": "Problem. We apply HARI to modeling a human-assisted navigation (HAN) problem. In HAN, a human requests an agent to find an object in an indoor environment. Each task request asks the agent to go to a room of type r and find an object of type o (e.g., find a mug in a kitchen). The agent is equipped with a camera and shares its camera view with the human. We assume that the human is sufficiently familiar with the environment that they can recognize the agent's location by looking at its current view. Before issuing a task request, the human imagines a goal location (but do not reveal it to the agent). We are primarily interested in evaluating success in goal-finding, i.e. whether the agent can arrive at the human's intended goal location. Even though there could be multiple locations that match a request, the agent only succeeds if it arrives exactly at the chosen goal location. We also determine success in request-fulfilling, where the agent successfully fulfills a request if it navigates to any node that is within two meters of an object that matches the request.\nWhile an agent is performing a task, it may request the human to provide additional information via telecommunication (e.g., a chat app). Specifically, it can ask for a description of its current location (CUR), the goal location (GOAL), or a subgoal location that is on the path from its current location to the goal location (SUB). Detail about how the subgoals are determined is in the Appendix.\nOperation Environment. We construct the operation environments using the environment graphs provided by the Matterport3D simulator. Each environment graph is generated from a 3D model of a house where each node is a location in the house and each edge connects two nearby unobstructed locations. Each operation state s corresponds to a node in the graph. At any time, the agent's operation action space A consists of traversing to any of the nodes that are adjacent to its current node.\nWe employ a discrete bag-of-features representation for state descriptions. 3 A bag of features represents the information that the agent extracts from the raw input that the agent perceives (e.g., an image, a language sentence). Working with this intermediate input allows us to easily vary the type and amount of information given to the agent. Specifically, we simulate two settings of descriptions: dense and sparse. At evaluation time, the agent perceives sparse descriptions and request the assistant for dense descriptions. A dense description of a current location contains the room name at the location, and the features of M objects restricted to be within δ meters of the location. The features of each object consists of (i) its name, (ii) horizontal and vertical angles (relative to the current viewpoint), and (iii) distance (in meters) from the object to the current location. A dense description of a goal follows the same representation scheme. In the sparse setting, the current-location description does not include the room name. Moreover, we remove the features of objects that are not in the top 100 most frequent objects, emulating an imperfect object detector module. The sparse goal description (the task request) has only features of the target object and the room name where the object is located at. Especially, if a subgoal location is adjacent or coincides with the agent's current location, instead of describing room and object features, the human specifies the ground-truth action to go to the subgoal (an action is specified by its horizontal and vertical angles, and travel distance). 4   Experimental Procedure. We conduct our experiments in three phases. In the pre-training phase, we learn an operation policy π with dense descriptions of the current location and the goal. In the training phase, the agent perceives a sparse description of its current location and is given a sparse initial goal description. We use advantage actor-critic to learn an interaction policy ψ θ that controls how the agent communicates with the human and navigates in an environment. The human always returns dense descriptions. The interaction policy is trained in environments that are previously seen as well as unseen during pre-training. Finally, in the evaluation phase, the interaction policy is tested on three conditions: seen environment and target object type but starting from a new room (UNSEENSTR), seen environment but new target object type (UNSEENOBJ), and new environment (UNSEENENV).\nOperation Environment. We construct the operation environments using the environment graphs provided by the Matterport3D simulator (Anderson et al., 2018). Each environment graph is generated from a 3D model of a house where each node is a location in the house and each edge connects two nearby unobstructed locations. Each operation state s corresponds to a node in the graph. At any time, the agent’s operation action space A consists of traversing to any of the nodes that are adjacent to its current node.

Developer productivity is increased as teams dedicated to the single responsibility service can control releases independent of other services.  They can also control the language the service is written in.  This is helpful when certain services might benefit from being written in Python vs C#, Java or Javascript.  Microservices advocate for an event driven architecture where services are not coupled or referenced directly.  Each Microservice can publish events that can be consumed/subscribed by other services.  Containerization and Microservices go well together when designing Microservices, considering that the paradigm calls for Containers to be immutable and treated as Cattle.  New and Old versions of the same Microservice can be released side by side in an A/B pattern, helping with assurance of any updates.

In fact, online harassment becomes very common in Twitter and there have been a lot of critics that Twitter has become the platform for many racists, misogynists and hate groups which can express themselves openly. Online harassment is usually in the form of verbal or graphical formats and is considered harassment, because it is neither invited nor has the consent of the receipt. Monitoring the contents including sexism and sexual harassment in traditional media is easier than monitoring on the online social media platforms like Twitter. The main reason is because of the large amount of user generated content in these media. So, the research about the automated detection of content containing sexual harassment is an important issue and could be the basis for removing that content or flagging it for human evaluation. The basic goal of this automatic classification is that it will significantly improve the process of detecting these types of hate speech on social media by reducing the time and effort required by human beings.\nPrevious studies have been focused on collecting data about sexism and racism in very broad terms or have proposed two categories of sexism as benevolent or hostile sexism BIBREF0, which undermines other types of online harassment. However, there is no much study focusing on different types online harassment alone attracting natural language processing techniques.\nIn this paper we present our work, which is a part of the SociaL Media And Harassment Competition of the ECML PKDD 2019 Conference. The topic of the competition is the classification of different types of harassment and it is divided in two tasks. The first one is the classification of the tweets in harassment and non-harassment categories, while the second one is the classification in specific harassment categories like indirect harassment, physical and sexual harassment as well. We are using the dataset of the competition, which includes text from tweets having the aforementioned categories. Our approach is based on the Recurrent Neural Networks and particularly we are using a deep, classification specific attention mechanism. Moreover, we present a comparison between different variations of this attention-based approach like multi-attention and single attention models. The next Section includes a short description of the related work, while the third Section includes a description of the dataset. After that, we describe our methodology. Finally, we describe the experiments and we present the results and our conclusion.\nIn the era of social media and networking platforms, Twitter has been doomed for abuse and harassment toward users specifically women. In fact, online harassment becomes very common in Twitter and there have been a lot of critics that Twitter has become the platform for many racists, misogynists and hate groups which can express themselves openly. Online harassment is usually in the form of verbal or graphical formats and is considered harassment, because it is neither invited nor has the consent of the receipt. Monitoring the contents including sexism and sexual harassment in traditional media is easier than monitoring on the online social media platforms like Twitter. The main reason is because of the large amount of user generated content in these media.",

        "evidence": "“Laughter is the best Medicine” is a saying which is popular with most of the people. Humor is a form of communication that bridges the gap between various languages, cultures, ages and demographics. That's why humorous content with funny and witty hashtags are so much popular on social media. It is a very powerful tool to connect with the audience. Automatic Humor Recognition is the task of determining whether a text contains some level of humorous content or not. First conference on Computational humor was organized in 1996, since then many research have been done in this field. kao2016computational does pun detection in one-liners and dehumor detects humor in Yelp reviews. Because of the complex and interesting aspects involved in detecting humor in texts, it is one of the challenging research field in Natural Language Processing BIBREF3 . Identifying humor in a sentence sometimes require a great amount of external knowledge to completely understand it. There are many types of humor, namely anecdotes, fantasy, insult, irony, jokes, quote, self deprecation etc BIBREF4 , BIBREF5 . Most of the times there are different meanings hidden inside a sentence which is grasped differently by individuals, making the task of humor identification difficult, which is why the development of a generalized algorithm to classify different type of humor is a challenging task.\nMajority of the researches on social media texts is focused on English. A study by schroeder2010half shows that, a high percentage of these texts are in non-English languages. fischer2011language gives some interesting information about the languages used on Twitter based on the geographical locations. With a huge amount of such user generated data available on social media, there is a need to develop technologies for non-English languages. In multilingual regions like South Asia, majority of the social media users speak more than two languages. In India, Hindi is the most spoken language (spoken by 41% of the population) and English is the official language of the country. Twitter has around 23.2 million monthly active users in India. Native speakers of Hindi often put English words in the sentences and transliterate the whole sentence to Latin script while posting on social media, thereby making the task of automatic text classification a very challenging problem. Linguists came up with a term for any type of language mixing, known as `code-mixing' or `code-switching' BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . Both the terms are used interchangeably, but there is a slight difference between the two terms. Code-mixing refers to the insertion of words, phrases, and morphemes of one language into a statement or an expression of another language, whereas transliteration of every word in a sentence to another script ( here Devanagari to Latin) is coined code-switching BIBREF10 . The first tweet in Figure 1 is an example of code-mixing and second is an example of code-switching. In this paper, we use code-mixing to denote both cases.\nIn this paper, we present a freely available corpus containing code-mixed tweets in Hindi and English language with tweets written in Latin script. Tweets are manually classified into humorous and non-humorous classes. Moreover, each token in the tweets is also given a language tag which determines the source or origin language of the token (English or Hindi). The paper is divided in sections as follows, we start by describing the corpus and the annotation scheme in Section 2. Section 3 summarizes our supervised classification system which includes pre-processing of the tweets in the dataset and the feature extraction followed by the method used to identify humor in tweets. In the next subsection, we describe the classification model and the results of the experiments conducted using character and word level features. In the last section, we conclude the paper followed by future work and references.\nIn this paper, we present a freely available corpus containing code-mixed tweets in Hindi and English language with tweets written in Latin script.",

        "question": "What is the major contribution of your work?",
        "answer": "When solving the activation space attack using a generic MIP solver like Gurobi or CPLEX, the generic MIP solver can be very inefficient because it cannot exploit the structure of the neural networks to speed up solving, cannot utilize information from cheap adversarial attacks (e.g., PGD attacks), and also can hardly be accelerated on GPUs. So although attacks on activation space can be powerful, they are extremely slow using a generic MIP solver.\nOur work solves these weaknesses using a specialized top-down beam search and bottom-up large neighborhood search. We use bound propagation methods to exploit the structure of the networks to speedup solving; we maintain a pool of existing adversarial examples to guide the search in activation space; our search is also accelerated on GPUs via specialized neural network verifiers.\nBy overcoming these drawbacks in a generic MIP solver, we greatly improved adversarial example search on the activation space: we can find more adversarial examples and also be over a magnitude faster than the generic MIP solver on most models.",
        "evidence": "Adversarial attacks aim to find adversarial examples, which are close to benign inputs in certain distance metrics yet trigger wrong behavior of neural networks. Adversarial attacks are important tools to gauge the empirical robustness of deep neural networks. Finding an adversarial example can be generally formulated as a constrained optimization problem:\nwhere C is often an ∞ or 2 norm ball around the original input x 0 , and f (x) is an attack success criterion involving a neural network (such as the margin between the groundtruth class and another class): f (x) < 0 indicates a successful attack. A straightforward way of solving Eq. () is via firstorder constrained optimization methods, such as projected gradient descent (PGD) and its variants. Additionally, some gradient-free attacks were proposed, mostly based on certain heuristic search on the input space x.\nLimitations of existing attacks. As f (x) usually consists of a highly non-convex neural network, solving Eq. () to its global minimum is challenging. This leads to failures in adversarial attacks: an adversarial example may exist but no attacks can find it, giving a false sense of security. Especially, gradient based attacks can be easily trapped into a local minimum or misguided by masked gradients. Even if we give the attacker an infinite amount of time (e.g., run a very large number of PGD steps, or allowing a large number of samples on input space), it is still hard to guarantee to find the adversarial example, since it is extremely difficult to systematically search the high dimensional and continuous input space. Models concluded robust under existing attacks might still have security vulnerability in practice, leading to an urgent request for stronger attacks that can possibly approach ground-truth robustness.\nThe mixed-integer approach. This paper seeks stronger adversarial attacks from a different angle: instead of searching for adversarial examples in the input space, we look for adversarial examples in the activation space. The main intuition is that neural networks with piece-wise linear activation functions (e.g., ReLU) can be seen as a piece-wise linear function and each piece is uniquely defined by a specific setting of activation function status. For ReLU networks, each neuron can either be active (its input is positive) or inactive (its input is negative so the output is 0), which can be encoded by discrete 0-1 variables. This leads to a mixed integer programming (MIP) formulation, and  conducted attacks using a MIP solver.\nBenefits of the MIP formulation. The MIP formulation with the 0-1 encoding of ReLU neurons allows us to systematically search all the linear pieces in the input space, theoretically guarantee to enumerate the entire input space and obtain the global minimum of Eq. () given sufficient time.\nPractically, MIP-based attacks can often find adversarial examples that are missed by existing attacks and identify true weaknesses of a model. It also helps to close the gap between the upper and lower bounds of robust accuracy (i.e., attack accuracy vs. verified accuracy). Existing works aimed to reducing this gap by tightening the lower bound with stronger verifiers, while our work aims to tighten the upper bound by a systematic search of adversarial examples. Closing this gap is difficult even on small models.\nGeneric MIP solvers are inefficient for adversarial attacks. Despite its strengths, a MIP-based attack are often a few orders of magnitudes slower than existing attacks due to the high cost of running an off-the-shelf solver such as Gurobi . There are three root causes for its inefficiency. First, an off-the-shelf solver is not aware of the underlying optimization problem corresponds to a neural network, and has to apply generic solving techniques (e.g., using Simplex algorithm with relaxations) which can be expensive or ineffective. Second, it cannot utilize solutions obtained cheaply from gradient based attacks to accelerate its search. Third, generic MIP solvers are mostly restricted to CPUs and can hardly utilize GPU acceleration, which is crucial for efficiency.\nContributions of this paper. We address the above weaknesses in MIP solvers for adversarial attacks, by developing a GPU-accelerated branch and bound procedure to systematically search adversarial examples in the activation space, which is more efficient than generic MIP solvers. We focus on solving hard instances, where none of existing adversarial attacks based on searching the input space are successful but no verifier can prove their robustness. Our contributions includes:\n• We apply the GPU-accelerated bound propagation based methods, which were originally developed for neural network verification, to the adversarial attack setting. These specialized methods can quickly examine thousands of regions in activation space in parallel and rule out the regions with no adversarial examples, which is difficult in off-the-shelf MIP solvers with a generic solving procedure.\n• We employ a top-down beam-search to explore the activation space. • Our new attack framework, BaB-Attack, is designed to tackle hard instances where existing strong adversarial attacks (such as AutoAttack) cannot succeed. Despite being more expensive than attacks on the input space, BaB-Attack is about an order of magnitude faster than using an MIP solver on hard instances, and can find adversarial examples that cannot be discovered by any existing attacks.\nContributions of this paper.

Unlike the best-first search scheme used in many neural network verifiers, we can quickly go deep in the search tree and identify the most promising regions with adversarial examples. A smaller sub-MIP can then be created on- the-fly to search adversarial examples in the reduced regions with much fewer integer variables.\n•We collect adversarial examples generated by cheap attacks in a candidate pool and utilize them in two ways. First, we conduct a bottom-up search on examples close to decision boundary by applying large neighborhood search (LNS). Second, when conducting the top-down search, we adopt diving by fixing integer variables according to adversarial examples in the pool to reduce the search space.\n•Our new attack framework, BaB-Attack, is designed to tackle hard instances where existing strong adversarial attacks (such as AutoAttack) cannot succeed.

As Chancellor, Osborne's tenure pursued austerity policies aimed at reducing the budget deficit and launched the Northern Powerhouse initiative. After the Conservatives won an overall majority in the 2015 general election, Cameron reappointed him Chancellor in his second government and gave him the additional title of First Secretary of State. He was widely viewed as a potential successor to David Cameron as Leader of the Conservative Party; one Conservative MP, Nadhim Zahawi, suggested that the closeness of his relationship with Cameron meant that the two effectively shared power during the duration of the Cameron governments.

        "answer": "An off-the shelf Logistic Regression model",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nWe perform classification experiments with an off-the shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019.",

One way to narrow your attention is to closely observe the sensation of cool air as it passes over the tip of your nose, and the sensation of your chest falling as you exhale. Allow any rising thoughts to pass through your mind without paying attention to them, or engaging with them.\n\nOther techniques involve focusing your attention to sensations in your body like hot and cold, or pain. You can also bring your focus to feelings like fear, anxiety, or love - focus your attention on where exactly in the body you feel those feelings. You can also move your attention to external stimulus like sounds, and your visual field.\n\nMindfulness is an extremely powerful technique that anyone can do from anywhere. Good luck practicing!",

        "evidence": "Text simplification aims to reduce the lexical and structural complexity of a text, while still retaining the semantic meaning, which can help children, non-native speakers, and people with cognitive disabilities, to understand text better. One of the methods of automatic text simplification can be generally divided into three categories: lexical simplification (LS) BIBREF0 , BIBREF1 , rule-based BIBREF2 , and machine translation (MT) BIBREF3 , BIBREF4 . LS is mainly used to simplify text by substituting infrequent and difficult words with frequent and easier words. However, there are several challenges for the LS approach: a great number of transformation rules are required for reasonable coverage and should be applied based on the specific context; third, the syntax and semantic meaning of the sentence is hard to retain. Rule-based approaches use hand-crafted rules for lexical and syntactic simplification, for example, substituting difficult words in a predefined vocabulary. However, such approaches need a lot of human-involvement to manually define these rules, and it is impossible to give all possible simplification rules. MT-based approach has attracted great attention in the last several years, which addresses text simplification as a monolingual machine translation problem translating from 'ordinary' and 'simplified' sentences.\nIn recent years, neural Machine Translation (NMT) is a newly-proposed deep learning approach and achieves very impressive results BIBREF5 , BIBREF6 , BIBREF7 . Unlike the traditional phrased-based machine translation system which operates on small components separately, NMT system is being trained end-to-end, without the need to have external decoders, language models or phrase tables. Therefore, the existing architectures in NMT are used for text simplification BIBREF8 , BIBREF4 . However, most recent work using NMT is limited to the training data that are scarce and expensive to build. Language models trained on simplified corpora have played a central role in statistical text simplification BIBREF9 , BIBREF10 . One main reason is the amount of available simplified corpora typically far exceeds the amount of parallel data. The performance of models can be typically improved when trained on more data. Therefore, we expect simplified corpora to be especially helpful for NMT models.\nIn contrast to previous work, which uses the existing NMT models, we explore strategy to include simplified training corpora in the training process without changing the neural network architecture. We first propose to pair simplified training sentences with synthetic ordinary sentences during training, and treat this synthetic data as additional training data. We obtain synthetic ordinary sentences through back-translation, i.e. an automatic translation of the simplified sentence into the ordinary sentence BIBREF11 . Then, we mix the synthetic data into the original (simplified-ordinary) data to train NMT model. Experimental results on two publicly available datasets show that we can improve the text simplification quality of NMT models by mixing simplified sentences into the training set over NMT model only using the original training data.\nText simplification aims to reduce the lexical and structural complexity of a text, while still retaining the semantic meaning, which can help children, non-native speakers, and people with cognitive disabilities, to understand text better.",

        "evidence": "We also consider the role of the pretraining dataset and model size. We conduct active learning experiments with 3 pretrained models: BiT-S-R50x1, BiT-M-R50x1, BiT-M-R101x1, and their corresponding non-pretrained versions. For all pretrained models (except BiT-M R-101 for Treeperson) Review rating uncertainty acquisition outperformed random acquisition (Figure, Figure, Figure). Importantly, we did not see any gains from AL on the unpretrained models, even when exploring a range of different hyperparameter configurations.\nScaling trend Interestingly, the BiT-S-R50x1 model, which was pretrained on a smaller dataset than the BiT-M models (ImageNet-1k vs ImageNet-21k) achieves less of a boost from active learning on iWildCam vs the other two models. This suggests that the gains from active learning may continue to grow as pretained models are trained for longer on more data. However, we did not see a difference between BiT-M-50x1 and BiT-M-101x1, which were trained on the same dataset but have different numbers of parameters. We encourage future work that more thoroughly examines these behaviors and scaling laws across a range of models and datasets.\nImpact of pretraining on acquisition patters Pretrained models also acquire disambiguating subgroups much more efficiently than their unpretrained counterparts. See Appendix G for additional figures and results illustrating this point.\nWhy does pretraining improve AL for resolving task ambiguity? We investigate the hypothesis that pretrained representations enable AL models to select objects based on higher-level features (e.g. object foreground and background) through various analyses on Waterbirds.\nWe investigate the presence of these high-level features by training linear classifiers on the second to last layer of BiT models. The classifiers are trained to predict each image's bird type and background type (4 classes, each comprising 25% of the data). As shown in Figure, these classes are more linearly separable in pretrained models both before any finetuning, as well as after finetuning on a seed set and then acquired examples from the original 2class Waterbirds dataset. This demonstrates that pretrained models can better identify both the causal and spurious features in the data, potentially explaining why they can choose them preferentially. Figure: Uncertainty sampling only provides gains when using pretrained models. S-R50, M-R50, and M-R101 correspond to the BiT-S-R50x1, BiT-M-R50x1, and BiT-M-R101x1 pretrained models, respectively, while R50-NP and R101NP correspond to ResNet models which are not pretrained. Shaded regions represent 95% CIs (Gaussian approx.).\nWe visualize the second-to-last layer embeddings of BiT (without any finetuning) using t-SNE (van der Maaten & Hinton, 2008), shown in Figure. We find that examples selected by uncertainty sampling fall closer to the decision boundary for the pretrained model than for the unpretrained model. We also see that the pretrained model exhibits far more separation by class, suggesting it is better able to identify useful features in the input. These conclusions help further characterize how pretraining provides a feature space more amenable to active learning.\nFigure 5: Uncertainty sampling upsamples both visible and latent minority subgroups. Fraction of Amazon examples acquired by random and uncertainty sampling, stratified by star rating and product category. Uncertainty sampling preferentially acquires examples with lower star ratings and rarer product categories, despite the latter attribute not being visible to the model.****As shown in Figure 6, these classes are more linearly separable in pretrained models both before any finetuning, as well as after finetuning on a seed set and then acquired examples from the original 2- class Waterbirds dataset. This demonstrates that pretrained models can better identify both the causal and spurious features in the data, potentially explaining why they can choose them preferentially.",

However, neither where coffee was first cultivated nor direct evidence of its consumption prior to the 15th century have been found. Sufi monasteries in Yemen employed coffee as an aid to concentration during prayers. Coffee later spread to the Levant and Persia in the early 16th century; it caused some controversy on whether it was halal in Ottoman and Mamluk society. Coffee arrived in Italy the second half of the 16th century through commercial Mediterranean trade routes, while Central and Eastern Europeans learnt of coffee from the Ottomans. By the mid 17th century, it had reached India and the East Indies.\n\nCoffee houses would establish themselves in Western Europe by the late 17th century, especially in England and Germany. One of the earliest cultivations of coffee in the New World was when Gabriel de Clieu brought coffee seedlings to Martinique in 1720. These beans later sprouted 18,680 coffee trees which enabled its spread to other Caribbean islands like Saint-Domingue and also to Mexico. By 1788, Saint-Domingue supplied half the world's coffee.\n\nBy 1852, globally, Brazil became the largest producer of coffee and has held that status ever since. The period since 1950 saw the widening of the playing field due to the emergence of several other major producers, notably Colombia, Ivory Coast, Ethiopia, and Vietnam; the latter overtook Colombia and became the second-largest producer in 1999.

In this paper, we re-assess the performance of several state-of-the-art keyphrase extraction models at increasingly sophisticated levels of preprocessing. Three incremental levels of document preprocessing are experimented with: raw text, text cleaning through document logical structure detection, and removal of keyphrase sparse sections of the document.

The crosslingual latent variables capture correlations between roles in different languages, and regularize the parameter estimates of the monolingual models. Because this is a joint Bayesian model of multilingual SRI, we can apply the same model to a variety of training scenarios just by changing the inference procedure appropriately. We evaluate monolingual SRI with a large unlabeled dataset, bilingual SRI with a parallel corpus, bilingual SRI with annotations available for the source language, and monolingual SRI with a small labeled dataset. Increasing the amount of monolingual unlabeled data significantly improves SRI in German but not in English. Adding word alignments in parallel sentences results in small, non significant improvements, even if there is some labeled data available in the source language. This difficulty in showing the usefulness of parallel corpora for SRI may be due to the current assumptions about role alignments, which mean that only a small percentage of roles are aligned. Further analyses reveals that annotating small amounts of data can easily outperform the performance gains obtained by adding large unlabeled dataset as well as adding parallel corpora.\nFuture work includes training on different language pairs, on more than two languages, and with more inclusive models of role alignment.\nWe evaluate monolingual SRI with a large unlabeled dataset, bilingual SRI with a parallel corpus, bilingual SRI with annotations available for the source language, and monolingual SRI with a small labeled dataset.",

        "question": "What novel task does the paper propose?",
        "answer": "Concept-map-based MDS.",
        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ). We make these resources publicly available under a permissive license.\nIn this paper, we propose a novel task, concept-map-based MDS, present a new crowdsourcing scheme to create reference summaries publish a new dataset for the proposed task and provide an evaluation protocol and baseline.",

We do not let our agent access this additional solution information or admissible actions list. Given the relatively small quest length for TextWorld games—games can be completed in as little as 5 steps—we generate 50 such games and partition them into train and test sets in a 4:1 ratio.

For example, Anchorhead is segmented into 3 chapters in the form of objectives spread across 3 days, of which we use only the first chapter.

        "question": "Why did the founders of YouTube start with money?",
        "evidence": "YouTube was founded by Steve Chen, Chad Hurley, and Jawed Karim. The trio were early employees of PayPal, which left them enriched after the company was bought by eBay. Hurley had studied design at the Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois Urbana-Champaign.\n\nAccording to a story that has often been repeated in the media, Hurley and Chen developed the idea for YouTube during the early months of 2005, after they had experienced difficulty sharing videos that had been shot at a dinner party at Chen's apartment in San Francisco. Karim did not attend the party and denied that it had occurred, but Chen remarked that the idea that YouTube was founded after a dinner party \"was probably very strengthened by marketing ideas around creating a story that was very digestible\".\n\nKarim said the inspiration for YouTube first came from the Super Bowl XXXVIII halftime show controversy, when Janet Jackson's breast was briefly exposed by Justin Timberlake during the halftime show. Karim could not easily find video clips of the incident and the 2004 Indian Ocean Tsunami online, which led to the idea of a video-sharing site. Hurley and Chen said that the original idea for YouTube was a video version of an online dating service and had been influenced by the website Hot or Not. They created posts on Craigslist asking attractive women to upload videos of themselves to YouTube in exchange for a $100 reward. Difficulty in finding enough dating videos led to a change of plans, with the site's founders deciding to accept uploads of any video.\n\n\nThe YouTube logo used from its launch until 2007; it returned in 2008 before being removed again in 2010. Another version of this logo without the \"Broadcast Yourself\" slogan was used until 2011.\nYouTube began as a venture capital–funded technology startup. Between November 2005 and April 2006, the company raised money from various investors, with Sequoia Capital, $11.5 million, and Artis Capital Management, $8 million, being the largest two. YouTube's early headquarters were situated above a pizzeria and a Japanese restaurant in San Mateo, California. In February 2005, the company activated www.youtube.com. The first video was uploaded April 23, 2005. Titled Me at the zoo, it shows co-founder Jawed Karim at the San Diego Zoo and can still be viewed on the site. In May, the company launched a public beta and by November, a Nike ad featuring Ronaldinho became the first video to reach one million total views. The site launched officially on December 15, 2005, by which time the site was receiving 8 million views a day. Clips at the time were limited to 100 megabytes, as little as 30 seconds of footage.\n\nYouTube was not the first video-sharing site on the Internet; Vimeo was launched in November 2004, though that site remained a side project of its developers from CollegeHumor at the time and did not grow much, either. The week of YouTube's launch, NBC-Universal's Saturday Night Live ran a skit \"Lazy Sunday\" by The Lonely Island. Besides helping to bolster ratings and long-term viewership for Saturday Night Live, \"Lazy Sunday\"'s status as an early viral video helped establish YouTube as an important website. Unofficial uploads of the skit to YouTube drew in more than five million collective views by February 2006 before they were removed when NBCUniversal requested it two months later based on copyright concerns. Despite eventually being taken down, these duplicate uploads of the skit helped popularize YouTube's reach and led to the upload of more third-party content. The site grew rapidly; in July 2006, the company announced that more than 65,000 new videos were being uploaded every day and that the site was receiving 100 million video views per day.\n\nThe choice of the name www.youtube.com led to problems for a similarly named website, www.utube.com. That site's owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube subsequently changed its website to www.utubeonline.com.",

        "question": "The authors should explain a bit more the intuition behind these graph signatures. What type of dynamics do they capture? What do they reveal about the architecture? What is the advantage in comparison to other graph features (local or global)?",
        "answer": "Based on your feedback, we have updated our paper (Sec. 3.2 (S2) and (S3)) with additional justifications and intuition behind the graph features that we leverage during the signature construction step (degree and eigenvector centrality). We chose weighted degree centrality to efficiently capture (1) the weights that are learned in each layer of the NN at the node level (filter or neuron), which are the most important aspect of the training process; and (2) the change of the learned weights during the training process of NN over time (in the proposed time-evolving graph representation). Moreover, we use the node degrees to model the NN structure since they have been found to be effective in capturing the structural roles of nodes and a key notion for structural node embedding [1]. We note that we show the difference in how the degree-based signatures change during the training process for low accuracy NNs vs. high accuracy ones in Figure-7-9 in the appendix.\nEigenvector centrality is used to capture the highly influential nodes in a graph; in our case, the nodes correspond to filters of convolutional layers and neurons of fully connected layers. Additionally, eigenvector centrality has been used for detecting communities [2] or clusters [3], and thus provides structural information about the clusterability of the NN. Clusters or communities are central for network analysis and provide complementary information compared to the simpler and more efficient-to-compute degree centrality. Our hypothesis was that tracking changes in the eigenvector centrality (or node influence or clustering-related information) over time could provide complementary insights into the structural changes of the NN during training that may correlate with high or low performance. Global vs. local properties: Our proposed framework requires global graph summaries in order to be able to compare different NN-based graphs (with different number of nodes and edges) in the training set; we achieved this by computing statistical summaries (signatures) of graph properties that capture the structure locally at the node level and are efficient to compute (so that our approach adds little overhead). We also experimented with other global features such as algebraic connectivity, modularity, and average shortest paths, but those fail to capture the structural changes in our graphs and lead to poor classification performance (they remain constant at different timestamps of the represented graphs).",
        "evidence": "A key objective of our work is to test whether the introduced graph representation of NNs is informative for predicting the performance of NNs. Next, we describe the steps of our proposed framework for solving Problem 1, namely performance prediction from the NN training dynamics.\nAs shown in Fig., our method consists of four steps: (S1) generation of a temporal graph for the training phase of each NN; (S2) extraction of node features; (S3) construction of a feature-based graph signature that captures the NN dynamics; (S4) prediction of NN performance by training a classifier or regressor on the constructed signatures. We describe these steps in more detail next.\n(S1) Graph generation. The first step involves converting the training process of each input NN into a time-evolving graph. Each NN N tri ∈ N , is represented as a series of checkpoints saved for t training epochs. Based on these checkpoints and the graph representation approaches for fc and conv layers presented in 2.2, 3.1 and 2.3, we first convert the τ th NN checkpoint into weighted graph G (τ ) i at timestamp/epoch τ . We note that although our proposed graph representation involves node features, our framework does not leverage them, and thus we consider the generated graphs unattributed. Therefore, each NN N tri is mapped to a time-evolving graph\nThe output of this step is a set of n time-evolving graphs {G tr1 , G tr2 , ..., G trn } corresponding to the original n NNs in N .\n(S2) Feature extraction. Next, the goal is to capture the structural dynamics of the NN training process. We aim to select graph measures that can capture changes during the training process, take into account the edge weight of graphs and can be calculated efficiently. In order to do that in an interpretable way, we extract two well-known node centralities from each snapshot of each generated time-evolving graph G i : weighted degree centrality and eigenvector centrality ( § 2.1). The weighted degree is a simple function of the learnable weight matrix W during the training phase of NN, therefore it gives us insights into the training dynamics at the node/neuron/filter level. The eigenvector centrality is an extension of the degree centrality, which captures the highly influential nodes, and has been successfully used in neuroscience to capture the dynamic changes of real neural networks (or connectomes). Eigenvector centrality can be used to capture importance and connectivity of filters/neurons (i.e., the nodes in our graph representation). Also, eigenvector centrality has been used for detecting communities or clusters, and thus provides structural information about the clusterability of the NN, which is complementary to that provided by the simpler and more efficient-to-compute degree centrality.\nOur choice of features is also guided by the inherent k-partite structure of our proposed graph representation, which cannot be represented well by several other commonly-used graph features. For example, clustering-based features (e.g., number of triangles, transitivity, clustering coefficient) and cycle-based metrics which account for closed paths in a graph are always equal to 0 for k-partite graphs. Moreover, connected component-related features (i.e., strong/weak connectivity) do not capture the learned edge weights, which are important for modeling the training dynamics of NNs. Other features (e.g., betweenness centrality) tend to be computationally expensive, and would add significant overhead compared to early stopping methods.\n(S3) Graph signature construction. In order to be able to compare NN-based graphs (with different number of nodes and edges), we summarize the structural changes in the generated time-evolving graphs at the graph level (rather than the node level, as in (S2)), and construct a statistical summary of the extracted node centralities (signature) per time-evolving graph G i . For each snapshot G (τ ) i of G i , we create a signature vector using five node feature aggregators, which were introduced in for graph similarity: median, mean, standard deviation, skewness, and kurtosis, where all but the median are moments of the corresponding distribution. Thus, G (τ ) i is mapped to a (static) signature vector s (τ ) i ∈ R 5 , representing the statistical summary of its node features (i.e., degree or eigenvector centrality) at time τ . To put more emphasis on the most recent timestamp, we can redefine the signature at time τ as the linear weighted average of the signatures up to that point,\n, or an exponential function of the previous signatures, s i ← αs\n. To obtain the temporal signature of the evolving graph G i , we aggregate the (static) signatures up to timestamp/epoch t:\n, where ⊕ denotes concatenation. We note that global features such as algebraic connectivity, modularity, and average shortest paths may be seen as alternative ways for constructing global graph signatures while circumventing the local feature extraction step (S2); however, these features fail to capture the structural changes in our proposed graph representations (they remain (near-)constant over time) and lead to poor performance.\n(S4) Performance prediction. For the last step of performance prediction, we consider two tasks: • Classification: We train a classifier (e.g., SVM, MLP) using the training graphs {G tr1 , G tr2 , ..., G trn } represented by their temporal signatures {s t tr1 , s t tr2 , ..., s t trn }, and their corresponding accuracies A = {α 1 , α 2 , . . . , α n } mapped to labels L = {l 1 , l 2 , . . . , l n } (e.g., high/low accuracy) based on some threshold. Any test NN instance is then classified using the trained classifier.\n• Linear regression: We perform linear regression to estimate the actual accuracy value α tst of a new test instance N tst based on its signature obtained through steps (S1)-(S3).\n(S2) Feature extraction. Next, the goal is to capture the structural dynamics of the NN training process. We aim to select graph measures that can capture changes during the training process, take into account the edge weight of graphs and can be calculated efficiently. In order to do that in an interpretable way, we extract two well-known node centralities from each snapshot of each generated time-evolving graph Gi : weighted degree centrality and eigenvector centrality (§ 2.1). The weighted degree is a simple function of the learnable weight matrix W during the training phase of NN, therefore it gives us insights into the training dynamics at the node/neuron/filter level. The eigenvector centrality is an extension of the degree centrality, which captures the highly influential nodes, and has been successfully used in neuroscience to capture the dynamic changes of real neural networks (or connectomes) (Lohmann et al., 2010). Eigenvector centrality can be used to capture importance and connectivity of filters/neurons (i.e., the nodes in our graph representation). Also, eigenvector centrality has been used for detecting communities (Newman, 2006) or clusters (Wu et al., 2013), and thus provides structural information about the clusterability of the NN, which is complementary to that provided by the simpler and more efficient-to-compute degree centrality.

        "evidence": "The Organization of the Petroleum Exporting Countries (OPEC, /ˈoʊpɛk/ OH-pek) is an organization enabling the co-operation of leading oil-producing countries, in order to collectively influence the global market and maximise profit. Founded on 14 September 1960 in Baghdad by the first five members (Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela), it has, since 1965, been headquartered in Vienna, Austria, although Austria is not an OPEC member state. As of September 2018, the 13 member countries accounted for an estimated 44 percent of global oil production and 81.5 percent of the world's proven oil reserves, giving OPEC a major influence on global oil prices that were previously determined by the so-called \"Seven Sisters\" grouping of multinational oil companies.\n\nThe formation of OPEC marked a turning point toward national sovereignty over natural resources, and OPEC decisions have come to play a prominent role in the global oil market and international relations. The effect can be particularly strong when wars or civil disorders lead to extended interruptions in supply. In the 1970s, restrictions in oil production led to a dramatic rise in oil prices and in the revenue and wealth of OPEC, with long-lasting and far-reaching consequences for the global economy. In the 1980s, OPEC began setting production targets for its member nations; generally, when the targets are reduced, oil prices increase. This has occurred most recently from the organization's 2008 and 2016 decisions to trim oversupply.\n\nEconomists have characterized OPEC as a textbook example of a cartel that cooperates to reduce market competition, but one whose consultations are protected by the doctrine of state immunity under international law. In the 1960s and 1970s, OPEC successfully restructured the global oil production system so that decision-making authority and the vast majority of profits is in the hands of oil-producing countries. Since the 1980s, OPEC has had a limited impact on world oil supply and price stability, as there is frequent cheating by members on their commitments to one another, and as member commitments reflect what they would do even in the absence of OPEC.\n\nCurrent OPEC members are Algeria, Angola, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, the Republic of the Congo, Saudi Arabia, the United Arab Emirates and Venezuela. Meanwhile, Ecuador, Indonesia and Qatar are former OPEC members. A larger group called OPEC+ was formed in late 2016 to have more control on the global crude oil market.",
        "answer": "The Organization of the Petroleum Exporting Countries (OPEC) was founded on September 14, 1960.  Economists describe OPEC as a cartel that limits free market competition by setting production quotas for its members. The impact of OPEC's supply quotas are most acute during times of war or civil disorder when crude oil supplies are already restricted. Cheating by member nations dilutes the power of OPEC over oil supply and prices.",

        "question": "Is it sufficient that the current use of emoji in the tokenizing, training, and the datasets themselves?",
        "answer": "No.",
        "evidence": "The prevalent use of emoji—and their text-based precursors—is mostly unaddressed in current natural language processing (NLP) tasks. The support of the Unicode Standard BIBREF0 for emoji characters in 2010 ushered in a wide-spread, international adoption of these graphical elements in casual contexts. Interpreting the meaning of these characters has been challenging however, since they take on multiple semantic roles BIBREF1.\nWhether or not emoji are used depends on the context of a text or conversation, with more formal settings generally being less tolerating. So is the popular aligned corpus Europarl BIBREF2 naturally devoid of emoji. Technical limitations, like no Unicode support, also limit its use. This in turn affects commonly used corpora, tokenizers, and pre-trained networks.\nTake for example the Ubuntu Dialog Corpus by BIBREF3, a commonly used corpus for multi-turn systems. This dataset was collected from an Internet Relay Chat (IRC) room casually discussing the operating system Ubuntu. IRC nodes usually support the ASCII text encoding, so there's no support for graphical emoji. However, in the 7,189,051 utterances, there are only 9946 happy emoticons (i.e. :-) and the cruelly denosed :) version) and 2125 sad emoticons.\nWord embeddings are also handling emoji poorly: Word2vec BIBREF4 with the commonly used pre-trained Google News vectors doesn't support the graphical emoji at all and vectors for textual emoticons are inconsistent. As another example with contextualized word embeddings, there are also no emoji or textual emoticons in the vocabulary list of BERT BIBREF5 by default and support for emoji is only recently added to the tokenizer. The same is true for GPT-2 BIBREF6. As all downstream systems, ranging from multilingual résumé parsing to fallacy detection BIBREF7, rely on the completeness of these embeddings, this lack of emoji support can affect the performance of some of these systems.\nAnother challenge is that emoji usage isn't static. Think of shifting conventions, different cultures, and newly added emoji to the Unicode list. Several applications also use their own custom emoji, like chat application Slack and streaming service Twitch. This becomes an issue for methods that leverage the Unicode description BIBREF8 or that rely on manual annotations BIBREF9.\nOur contribution with this paper is two-fold: firstly, we argue that the current use—or rather non-existing use—of emoji in the tokenizing, training, and the datasets themselves is insufficient. Secondly, we attempt to quantify the significance of incorporating emoji-based features by presenting a fine-tuned model. We then compare this model to a baseline, but without special attention to emoji.\nSection SECREF2 will start with an overview of work on emoji representations, emoji-based models and analysis of emoji usage. A brief introduction in conversational systems will also be given. Section SECREF3 will then look into popular datasets with and without emoji and then introduce the dataset we used.\nOur model will then be discussed in Section SECREF4, including the tokenization in Subsection SECREF4, training setup in Subsection SECREF6 and evaluation in Subsection SECREF10. This brings us to the results of our experiment, which is discussed in Section SECREF5 and finally our conclusion and future work are presented in Section SECREF6.\nfirstly, we argue that the current use—or rather non-existing use—of emoji in the tokenizing, training, and the datasets themselves is insufficient.",

The extension is in terms of user comments, which is another form of the text. Though seemingly useful, the step to include comments as another form of text is not that surprising technically.",
        "answer": "Although our method uses CLIP as a backbone since it is a natural fit for this task, it is not exclusive to CLIP and should be easily applicable to other models as well.We agree that leveraging comments is an intuitive idea, however, training with comments in practice is not straightforward since they’re often only weakly correlated with the video and can even hurt performance if used naively. Hence, the technical novelty is in introducing a method that is able to make use of the valuable information present in comments, while discarding the irrelevant ones.To summarise, our main technical contribution is two-fold: 1) introducing our proposed context-adapter module that is able to learn from noisy modalities, and 2) demonstrating for the first time that user comments can help video-text retrieval.",
        "evidence": "We use CLIP as the initialisation for the backbone. Our concrete implementation of the CAM g is a 2-layer transformer, consisting of two residual multihead self-attention blocks.\nThe input consists of M + 1 input embeddings (for the M comments and title/video embedding φ oi ) having 512 dimensions each. Each block performs 8-head self-attention on the inputs, followed by two linear layers with output size 2048 and 512 respectively. LayerNorm normalisation is used, along with GELU activation following the first linear layer. From the M + 1 outputs of the transformer, we take only the output at index 1 (the index of the text/video embedding), and pass it through a final 512 × 512 linear layer. We use learning rate 0.001 for training the CAM, and 1 × 10 −6 when training the entire model, using the Adam Kingma & Ba (2015) optimizer.\nAll implementation and architecture details can be found in the appendix.\nIn this work, we focus on multi-modal learning with a particular focus on learning video-text encoders for retrieval by proposing a novel, multi-modal adaptation module.\nVideo-text pretraining. Originating from the NLP domain, where the transformer architectures has been a key ingredient and subject to optimization in a multitude of ways, it has recently found applications in the vision-language domain. For example, recent works have leveraged transformers to learn generalizeable image or multi-modal image-text and video-multilingual text representations. A few works combine visual and text modalities as inputs to a BERT model to simultaneously learn semantic video and text representations. For representation learning, the availability of large-scale datasets such as HowTo100M has enabled more effective pretraining of video-text representations for multiple downstream tasks. More recently, show that adding a generative objective to contrastive pretraining can yield gains in video-text downstream tasks. Based on the CLIP model, which works well even without finetuning for some retrieval tasks, train video-text CLIP-initialized models by gradually scaling up video training from image training and a custom dataset. While we also start with a CLIP initialization as in, the focus of our paper lies in developing a novel method for leveraging user comments, a modality that has previously been overlooked in the text-video retrieval literature, as a valuable source of information. As is standard, the pretrained representations are subsequently evaluated on smaller datasets such as MSVD and MSR-VTT.\nMulti-modal domain adaptation. While residual adapters for domain adaptation have been explored for uni-modal models such as CNNs, e.g. in, there are no works that translate this concept to the multi-modal domain, where cross-modal learning dominates.\nThere is little prior work using user comments as additional context in multimodal settings. The use of user comments and reactions to refine predictions has been discussed by for minimising harms on facebook.com. Overall, we are the first to demonstrate that user comments can be used as a complementary modality when learning video-text representations.\nWe use CLIP (Radford et al., 2021) as the initialisation for the backbone.****While we also start with a CLIP initialization as in Luo et al.

However, note that we did not have access to the training data of ClaimBuster, which is not publicly available, and we thus train on our dataset (described above).\nSentiment (2 S features): Some sentences are highly negative, which can signal the presence of an interesting claim to check, as the two example sentences below show (from the 1st and the 2nd presidential debates):\n\nWe used the NRC sentiment lexicon BIBREF15 as a source of words and $n$-grams with positive/negative sentiment, and we counted the number of positive and of negative words in the target sentence. These features are different from those in the CB features above, where these lexicons were not used.\nNamed entities (NE) (1 S feature): Sentences that contain named entity mentions are more likely to contain a claim that is worth fact-checking as they discuss particular people, organizations, and locations. Thus, we have a feature that counts the number of named entity mentions in the target sentence; we use the NLTK toolkit for named entity recognition BIBREF16. Unlike the CB features above, here we only have one feature; we also use a different toolkit for named entity recognition.\nLinguistic features (9 S features): We count the number of words in each sentence that belong to each of the following lexicons: Language Bias lexicon BIBREF17, Opinion Negative and Positive Words BIBREF18, Factives and Assertive Predicates BIBREF19, Hedges BIBREF20, Implicatives BIBREF21, and Strong and Weak subjective words. Some examples are shown in Table TABREF12.\nTense (1 S feature): Most of the check-worthy claims mention past events. In order to detect when the speaker is making a reference to the past or s/he is talking about his/her future vision and plans, we include a feature with three values—indicating whether the text is in past, present, or future tense. The feature is extracted from the verbal expressions, using POS tags and a list of auxiliary verbs and phrases such as will, have to, etc.\nLength (1 S feature): Shorter sentences are generally less likely to contain a check-worthy claim. Thus, we have a feature for the length of the sentence in terms of characters. Note that this feature was not part of the CB features, as there length was modeled in terms of tokens, but here we do so using characters.\nThus, we have a feature that counts the number of named entity mentions in the target sentence; we use the NLTK toolkit for named entity recognition (Loper and Bird, 2002).",

Capa's brainchild, Magnum was a cooperative picture agency owned by its members. The team split photo assignments among the members. Rodger, who had quit Life in London after covering World War II, would cover Africa and the Middle East. Chim, who spoke a variety of European languages, would work in Europe. Cartier-Bresson would be assigned to India and China. Vandivert, who had also left Life, would work in America, and Capa would work anywhere that had an assignment. Maria Eisner managed the Paris office and Rita Vandivert, Vandivert's wife, managed the New York office and became Magnum's first president.\n\nCartier-Bresson achieved international recognition for his coverage of Gandhi's funeral in India in 1948 and the last stage of the Chinese Civil War in 1949. He covered the last six months of the Kuomintang administration and the first six months of the Maoist People's Republic. He also photographed the last surviving Imperial eunuchs in Beijing, as the city was being liberated by the communists. In Shanghai, he often worked in the company of photojournalist Sam Tata, whom Cartier-Bresson had previously befriended in Bombay. From China, he went on to Dutch East Indies (Indonesia), where he documented the gaining of independence from the Dutch. In 1950, Cartier-Bresson had traveled to the South India. He had visited Tiruvannamalai, a town in the Indian State of Tamil Nadu and photographed the last moments of Ramana Maharishi, Sri Ramana Ashram and its surroundings. A few days later he also visited and photographed Sri Aurobindo, Mother and Sri Aurobindo Ashram, Pondicherry.\n\nMagnum's mission was to \"feel the pulse\" of the times and some of its first projects were People Live Everywhere, Youth of the World, Women of the World and The Child Generation. Magnum aimed to use photography in the service of humanity, and provided arresting, widely viewed images.\n\nThe Decisive Moment\n\n1952 US edition of Cartier-Bresson's 1952 book The Decisive Moment (Images à la sauvette).\n\nPhotograph of Alberto Giacometti by Cartier-Bresson\nIn 1952, Cartier-Bresson published his book Images à la sauvette, whose English-language edition was titled The Decisive Moment, although the French language title actually translates as \"images on the sly\" or \"hastily taken images\", Images à la sauvette included a portfolio of 126 of his photos from the East and the West. The book's cover was drawn by Henri Matisse. For his 4,500-word philosophical preface, Cartier-Bresson took his keynote text from the 17th century Cardinal de Retz, \"Il n'y a rien dans ce monde qui n'ait un moment decisif\" (\"There is nothing in this world that does not have a decisive moment\"). Cartier-Bresson applied this to his photographic style. He said: \"Photographier: c'est dans un même instant et en une fraction de seconde reconnaître un fait et l'organisation rigoureuse de formes perçues visuellement qui expriment et signifient ce fait\" (\"To me, photography is the simultaneous recognition, in a fraction of a second, of the significance of an event as well as of a precise organization of forms which give that event its proper expression.\").\n\nBoth titles came from Tériade, the Greek-born French publisher whom Cartier-Bresson admired. He gave the book its French title, Images à la Sauvette, loosely translated as \"images on the run\" or \"stolen images.\" Dick Simon of Simon & Schuster came up with the English title The Decisive Moment. Margot Shore, Magnum's Paris bureau chief, translated Cartier-Bresson's French preface into English.\n\n\"Photography is not like painting,\" Cartier-Bresson told the Washington Post in 1957. \"There is a creative fraction of a second when you are taking a picture. Your eye must see a composition or an expression that life itself offers you, and you must know with intuition when to click the camera. That is the moment the photographer is creative,\" he said. \"Oop! The Moment! Once you miss it, it is gone forever.\"\n\nThe photo Rue Mouffetard, Paris, taken in 1954, has since become a classic example of Cartier-Bresson's ability to capture a decisive moment. He held his first exhibition in France at the Pavillon de Marsan in 1955.",

Morphological segmentation in LV-M appears to favor syntax less strongly than do simple n-grams.\nOn the downstream tasks, we only observe statistically significant ( $p < .05$ under a random permutation test) improvement on the chunking task, and it is a very small gain. We attribute this to both regular and subword models having very similar quality on frequent IV word representation. Statistically, these are the words are that are most likely to appear in the downstream task instances, and so the superior representation of rare words\nhas, due to their nature, little impact on overall accuracy. Because in all tasks OOV words are mapped to the “ $\\langle $ unk $\\rangle $ ” token, the subword models are not being used to the fullest, and in future work we will investigate whether generating representations for all words improves task performance.\nIn OOV representation (tab:oov), LV-N and FT work almost identically, as is to be expected. Both find highly coherent neighbors for the words “hellooo”, “marvelicious”, and “rereread”. Interestingly, the misspelling of “louisana” leads to coherent name-like neighbors, although none is the expected correct spelling “louisiana”. All models stumble on the made-up prefix “tuz”. A possible fix would be to down-weigh very rare subwords in the vector summation. LV-M is less robust than LV-N and FT on this task as it is highly sensitive to incorrect segmentation, exemplified in the “hellooo” example.\nFinally, we see that nearest-neighbors are a mixture of similarly pre/suffixed words. If these pre/suffixes are semantic, the neighbors are semantically related, else if syntactic they have similar syntactic function. This suggests that it should be possible to get tunable representations which are more driven by semantics or syntax by a weighted summation of subword vectors, given we can identify whether a pre/suffix is semantic or syntactic in nature and weigh them accordingly. This might be possible without supervision using corpus statistics as syntactic subwords are likely to be more frequent, and so could be down-weighted for more semantic representations. This is something we will pursue in future work.\nResults for IV evaluation are shown in table 1, and for OOV in table 2. Like in FT, the use of subword information in both LV-N and LV-M results in 1) better representation of rare words, as evidenced by the increase in RW correlation,",

        "answer": "The authors evaluated by comparing retrieval precision of real-valued and binary representations learned by it.",
        "evidence": "As pointed out by BIBREF3 , when working with large text collections one can use short binary codes for indexing and a representation with more capacity for ranking. Following this idea, we proposed Real-Binary PV-DBOW model (Section SECREF2 ) that can simultaneously learn short binary codes and high-dimensional real-valued representations. We begin evaluation of this model by comparing retrieval precision of real-valued and binary representations learned by it. To this end, we trained a Real-Binary PV-DBOW model with 28-bit binary codes and 300-dimensional real-valued representations on the 20 Newsgroups and RCV1 datasets. Results are reported in Figure FIGREF16 . The real-valued representations learned with this model give lower precision than PV-DBOW vectors but, importantly, improve precision over binary codes for top ranked documents. This justifies their use alongside binary codes.\nUsing short binary codes for initial filtering of documents comes with a tradeoff between the retrieval performance and the recall level. For example, one can select a small subset of similar documents by using 28–32 bit codes and retrieving documents within small Hamming distance to the query. This will improve retrieval performance, and possibly also precision, at the cost of recall. Conversely, short codes provide a less fine-grained hashing and can be used to index documents within larger Hamming distance to the query. They can therefore be used to improve recall at the cost of retrieval performance, and possibly also precision. For these reasons, we evaluated Real-Binary PV-DBOW models with different code sizes and under different limits on the Hamming distance to the query. In general, we cannot expect these models to achieve 100% recall under the test settings. Furthermore, recall will vary on query-by-query basis. We therefore decided to focus on the NDCG@10 metric in this evaluation, as it is suited for measuring model performance when a short list of relevant documents is sought, and the recall level is not known. MAP and precision-recall curves are not applicable in these settings.\nInformation retrieval results for Real-Binary PV-DBOW are summarized in Table TABREF19 . The model gives higher NDCG@10 than 32-bit Binary PV-DBOW codes (Table TABREF8 ). The difference is large when the initial filtering is restrictive, e.g. when using 28-bit codes and 1-2 bit Hamming distance limit. Real-Binary PV-DBOW can therefore be useful when one needs to quickly find a short list of relevant documents in a large text collection, and the recall level is not of primary importance. If needed, precision can be further improved by using plain Binary PV-DBOW codes for filtering and standard DBOW representation for raking (Table TABREF19 , column B). Note, however, that PV-DBOW model would then use approximately 10 times more parameters than Real-Binary PV-DBOW.\nFollowing this idea, we proposed Real-Binary PVDBOW model (Section 2) that can simultaneously learn short binary codes and high-dimensional real-valued representations.

The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only in English. Multi-racialism is enshrined in the constitution and continues to shape national policies in education, housing, and politics.\n\nSingapore's history dates back at least a millennium, having been a maritime emporium known as Temasek and subsequently as a major constituent part of several successive thalassocratic empires. Its contemporary era began in 1819 when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, the colonies in Southeast Asia were reorganised and Singapore came under the direct control of Britain as part of the Straits Settlements. During World War II, Singapore was occupied by Japan in 1942, and returned to British control as a separate Crown colony following Japan's surrender in 1945. Singapore gained self-governance in 1959 and in 1963 became part of the new federation of Malaysia, alongside Malaya, North Borneo, and Sarawak. Ideological differences, most notably the perceived encroachment of the egalitarian \"Malaysian Malaysia\" political ideology led by Lee Kuan Yew into the other constituent entities of Malaysia—at the perceived expense of the bumiputera and the policies of Ketuanan Melayu—eventually led to Singapore's expulsion from the federation two years later; Singapore became an independent sovereign country in 1965.",

Very few teams participated in TAC 2014 summarization track and the official results and the review paper of TAC 2014 systems were never published. Therefore, to evaluate the effectiveness of Rouge, we applied 9 well-known summarization approaches on the TAC 2014 scientific summarization dataset. Obtained Rouge and Sera results of each of these approaches are then correlated with semi-manual human judgments. In the following, we briefly describe each of these summarization approaches.\nLexRank BIBREF9 : LexRank finds the most important (central) sentences in a document by using random walks in a graph constructed from the document sentences. In this graph, the sentences are nodes and the similarity between the sentences determines the edges. Sentences are ranked according to their importance. Importance is measured in terms of centrality of the sentence — the total number of edges incident on the node (sentence) in the graph. The intuition behind LexRank is that a document can be summarized using the most central sentences in the document that capture its main aspects.\nLatent Semantic Analysis (LSA) based summarization BIBREF10 : In this summarization method, Singular Value Decomposition (SVD) BIBREF11 is used for deriving latent semantic structure of the document. The document is divided into sentences and a term-sentence matrix INLINEFORM0 is constructed. The matrix INLINEFORM1 is then decomposed into a number of linearly-independent singular vectors which represent the latent concepts in the document. This method, intuitively, decomposes the document into several latent topics and then selects the most representative sentences for each of these topics as the summary of the document.\nMaximal Marginal Relevance (MMR) BIBREF12 : Maximal Marginal Relevance (MMR) is a greedy strategy for selecting sentences for the summary. Sentences are added iteratively to the summary based on their relatedness to the document as well as their novelty with respect to the current summary.\nCitation based summarization BIBREF13 : In this method, citations are used for summarizing an article. Using the LexRank algorithm on the citation network of the article, top sentences are selected for the final summary.\nUsing frequency of the words BIBREF14 : In this method, which is one the earliest works in text summarization, raw word frequencies are used to estimate the saliency of sentences in the document. The most salient sentences are chosen for the final summary.\nSumBasic BIBREF15 : SumBasic is an approach that weights sentences based on the distribution of words that is derived from the document. Sentence selection is applied iteratively by selecting words with highest probability and then finding the highest scoring sentence that contains that word. The word weights are updated after each iteration to prevent selection of similar sentences.\nSummarization using citation-context and discourse structure BIBREF16 : In this method, the set of citations to the article are used to find the article sentences that directly reflect those citations (citation-contexts). In addition, the scientific discourse of the article is utilized to capture different aspects of the article. The scientific discourse usually follows a structure in which the authors first describe their hypothesis, then the methods, experiment, results and implications. Sentence selection is based on finding the most important sentences in each of the discourse facets of the document using the MMR heuristic.\nKL Divergence BIBREF17 In this method, the document unigram distribution INLINEFORM0 and the summary unigram distributation INLINEFORM1 are considered; the goal is to find a summary whose distribution is very close to the document distribution. The difference of the distributions is captured by the Kullback-Lieber (KL) divergence, denoted by INLINEFORM2 .\nSummarization based on Topic Models BIBREF17 : Instead of using unigram distributions for modeling the content distribution of the document and the summary, this method models the document content using an LDA based topic model BIBREF18 . It then uses the KL divergence between the document and the summary content models for selecting sentences for the summary.\nWe study the effectiveness of ROUGE and our proposed method (SERA) by analyzing the correlations with semi-manual human judgments. Very few teams participated in TAC 2014 summarization track and the official results and the review paper of TAC 2014 systems were never published.

SRL is the problem of finding predicate-argument structure in a sentence, as illustrated below:\n INLINEFORM0 \nHere, the predicate WRITE has two arguments: `Mike' as A0 or the writer, and `a book' as A1 or the thing written. The labels A0 and A1 correspond to the PropBank annotations BIBREF0 .\nAs the need for SRL arises in different domains and languages, the existing manually annotated corpora become insufficient to build supervised systems. This has motivated work on unsupervised SRL BIBREF1 , BIBREF2 , BIBREF3 . Previous work has indicated that unsupervised systems could benefit from the word alignment information in parallel text in two or more languages BIBREF4 , BIBREF5 , BIBREF6 . For example, consider the German translation of sentence INLINEFORM0 :\n INLINEFORM0 \nIf sentences INLINEFORM0 and INLINEFORM1 have the word alignments: Mike-Mike, written-geschrieben, and book-Buch, the system might be able to predict A1 for Buch, even if there is insufficient information in the monolingual German data to learn this assignment. Thus, in languages where the resources are sparse or not good enough, or the distributions are not informative, SRL systems could be made more accurate by using parallel data with resource rich or more amenable languages.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages. The model consists of individual Bayesian models for each language BIBREF3 , and crosslingual latent variables to incorporate soft role agreement between aligned constituents. This latent variable approach has been demonstrated to increase the performance in a multilingual unsupervised part-of-speech tagging model based on HMMs BIBREF4 .

In 1878, Booth reorganised the mission, becoming its first General and introducing the military structure which has been retained as a matter of tradition. Its highest priority is its Christian principles. The current international leader of The Salvation Army and chief executive officer (CEO) is General Brian Peddle, who was elected by the High Council of The Salvation Army on 3 August 2018.\n\nIn 2011, Charity Watch rated the Salvation Army an \"A−\" to an \"A\", indicating a high level of financial efficiency and organisational transparency. The Salvation Army has received an A-rating from the American Institute of Philanthropy.\n\nThe Salvation Army is one of the world's largest providers of social aid,[citation needed] with expenditures including operating costs of $2.6 billion in 2004, helping more than 32 million people in the U.S. alone. In addition to community centres and disaster relief, the organisation does work in refugee camps, especially among displaced people in Africa. In the United Kingdom, the Salvation Army is no longer the largest nongovernmental provider of social services; however, it still provides a significant service to people in need. The Salvation Army is the fourth largest charity in the United States, with private donations in excess of $2 billion in 2022, and is a member of the American organisation Christian Churches Together.",

        "answer": "Amazon Mechanical Turk.",
        "evidence": "With the expanding amount of text data generated on different social media platforms, current filters are insufficient to prevent the spread of hate speech. Most internet users involved in a study conducted by the Pew Research Center report having been subjected to offensive name calling online or witnessed someone being physically threatened or harassed online. Additionally, Amnesty International within Element AI have lately reported that many women politicians and journalists are assaulted every 30 seconds on Twitter. This is despite the Twitter policy condemning the promotion of violence against people on the basis of race, ethnicity, national origin, sexual orientation, gender identity, religious affiliation, age, disability, or serious disease. Hate speech may not represent the general opinion, yet it promotes the dehumanization of people who are typically from minority groups BIBREF0, BIBREF1 and can incite hate crime BIBREF2.\nMoreover, although people of various linguistic backgrounds are exposed to hate speech BIBREF3, BIBREF2, English is still at the center of existing work on toxic language analysis. Recently, some research studies have been conducted on languages such as German BIBREF4, Arabic BIBREF5, and Italian BIBREF6. However, such studies usually use monolingual corpora and do not contrast, or examine the correlations between online hate speech in different languages. On the other hand, tasks involving more than one language such as the hatEval task, which covers English and Spanish, include only separate classification tasks, namely (a) women and immigrants as target groups, (b) individual or generic hate and, (c) aggressive or non-aggressive hate speech.\nTreating hate speech classification as a binary task may not be enough to inspect the motivation and the behavior of the users promoting it and, how people would react to it. For instance, the hateful tweets presented in Figure FIGREF5 show toxicity directed towards different targets, with or without using slurs, and generating several types of reactions. We believe that, in order to balance between truth and subjectivity, there are at least five important aspects in hate speech analysis. Hence, our annotations indicate (a) whether the text is direct or indirect; (b) if it is offensive, disrespectful, hateful, fearful out of ignorance, abusive, or normal; (c) the attribute based on which it discriminates against an individual or a group of people; (d) the name of this group; and (e) how the annotators feel about its content within a range of negative to neutral sentiments. To the best of our knowledge there are no other hate speech datasets that attempt to capture fear out of ignorance in hateful tweets or examine how people react to hate speech. We claim that our multi-aspect annotation schema would provide a valuable insight into several linguistic and cultural differences and bias in hate speech.\nWe use Amazon Mechanical Turk to label around 13,000 potentially derogatory tweets in English, French, and Arabic based on the above mentioned aspects and, regard each aspect as a prediction task. Since in natural language processing, there is a peculiar interest in multitask learning, where different tasks can be used to help each other BIBREF7, BIBREF8, BIBREF9, we use a unified model to handle the annotated data in all three languages and five tasks. We adopt BIBREF8 as a learning algorithm adapted to loosely related tasks such as our five annotated aspects and, use the Babylon cross-lingual embeddings BIBREF10 to align the three languages. We compare the multilingual multitask learning settings with monolingual multitask, multilingual single-task, and monolingual single-task learning settings respectively. Then, we report the performance results of the different settings and discuss how each task affects the remaining ones. We release our dataset and code to the community to extend research work on multilingual hate speech detection and classification.\nWe use Amazon Mechanical Turk to label around 13,000 potentially derogatory tweets in English, French, and Arabic based on the above mentioned aspects and, regard each aspect as a prediction task.",

        "evidence": "Indicating that a web page is controversial, or disputed - for example, in a search result - facilitates an educated consumption of the information therein, suggesting the content may not represent the “full picture”. Here, we consider the problem of estimating the level of controversiality associated with a given Wikipedia concept (title). We demonstrate that the textual contexts in which the concept is referenced can be leveraged to facilitate this.\nThe definition of which concepts are controversial is controversial by itself; an accurate definition of this elusive notion attracted the attention of researchers from various fields, see for example some recent attempts in BIBREF0, BIBREF1, BIBREF2.\nMost people would agree, for example, that Global warming is a controversial concept, whereas Summer is not. However, the concept Pollution may be seen as neutral by some, yet controversial by others, who associate it with environmental debates. In other words, different people may have different opinions, potentially driven by different contexts salient in their mind. Yet, as reported in the sequel, an appreciable level of agreement can be reached, even without explicit context.\nFocusing here on Wikipedia concepts, we adopt as an initial “ground truth” the titles listed on the Wikipedia list of controversial issues, which is curated based on so-called “edit wars”. We then manually annotate a set of Wikipedia titles which are locked for editing, and evaluate our system on this much larger and more challenging dataset.\nTo estimate the level of controversy associated with a Wikipedia concept, we propose to simply examine the words in the sentences in which the concept is referenced. Because a concept can often be found in multiple contexts, the estimation can be seen as reflecting the “general opinion” about it in the corpus. This contrasts previous works, which consider this a binary problem, and employ a complex combination of features extracted from Wikipedia's article contents and inter-references, and more extensively – from the rich edit history thereof.\n. Jang et al. (2016) further build a language model, which enhances predictions made by existing classifiers, by inferring word probabilities from Wikipedia articles prominent in Wikipedia controversy features (mainly signals in edit history as discussed above) and from articles retrieved by manually selected query terms, believed to indicate controversy.",

While application of attention BIBREF2, BIBREF3 and advanced decoding mechanisms like beam search and variation sampling BIBREF4 have shown improvements, it does not solve the underlying problem. In creative text generation, the objective is not strongly bound to the ground truth—instead the objective is to generate diverse, unique or original samples. We attempt to do this through a discriminator which can give feedback to the generative model through a cost function that encourages sampling of creative tokens. The contributions of this paper are in the usage of a GAN framework to generate creative pieces of writing. Our experiments suggest that generative text models, while very good at encapsulating semantic, syntactic and domain information, perform better with external feedback from a discriminator for fine-tuning objectiveless decoding tasks like that of creative text. We show this by evaluating our model on three very different creative datasets containing poetry, metaphors and lyrics.\nPrevious work on handling the shortcomings of MLE include length-normalizing sentence probability BIBREF5, future cost estimation BIBREF6, diversity-boosting objective function BIBREF7, BIBREF1 or penalizing repeating tokens BIBREF8.

        "answer": "There are three phases.",
        "evidence": "The goal of this study was to annotate documents on a detailed level with respect to an argumentation model. First, we will present the annotation scheme. Second, we will describe the annotation process. Finally, we will evaluate the agreement and draw some conclusions.\nGiven the theoretical background briefly introduced in section SECREF2 , we motivate our selection of the argumentation model by the following requirements. First, the scope of this work is to capture argumentation within a single document, thus focusing on micro-level models. Second, there should exist empirical evidence that such a model has been used for analyzing argumentation in previous works, so it is likely to be suitable for our purposes of argumentative discourse analysis in user-generated content. Regarding the first requirement, two typical examples of micro-level models are the Toulmin's model BIBREF36 and Walton's schemes BIBREF55 . Let us now elaborate on the second requirement.\nWalton's argumentation schemes are claimed to be general and domain independent. Nevertheless, evidence from the computational linguistics field shows that the schemes lack coverage for analyzing real argumentation in natural language texts. In examining real-world political argumentation from BIBREF56 , Walton.2012 found out that 37.1% of the arguments collected did not fit any of the fourteen schemes they chose so they created new schemes ad-hoc. Cabrio2013b selected five argumentation schemes from Walton and map these patterns to discourse relation categories in the Penn Discourse TreeBank (PDTB) BIBREF48 , but later they had to define two new argumentation schemes that they discovered in PDTB. Similarly, Song.et.al.2014 admitted that the schemes are ambiguous and hard to directly apply for annotation, therefore they modified the schemes and created new ones that matched the data.\nAlthough Macagno.Konstantinidou.2012 show several examples of two argumentation schemes applied to few selected arguments in classroom experiments, empirical evidence presented by Anthony.Kim.2014 reveals many practical and theoretical difficulties of annotating dialogues with schemes in classroom deliberation, providing many details on the arbitrary selection of the sub-set of the schemes, the ambiguity of the scheme definitions, concluding that the presence of the authors during the experiment was essential for inferring and identifying the argument schemes BIBREF57 .\nAlthough this model (refer to section SECREF21 ) was designed to be applicable to real-life argumentation, there are numerous studies criticizing both the clarity of the model definition and the differentiation between elements of the model. Ball1994 claims that the model can be used only for the most simple arguments and fails on the complex ones. Also Freeman1991 and other argumentation theorists criticize the usefulness of Toulmin's framework for the description of real-life argumentative texts. However, others have advocated the model and claimed that it can be applied to the people's ordinary argumenation BIBREF58 , BIBREF59 .\nA number of studies (outside the field of computational linguistics) used Toulmin's model as their backbone argumentation framework. Chambliss1995 experimented with analyzing 20 written documents in a classroom setting in order to find the argument patterns and parts. Simosi2003 examined employees' argumentation to resolve conflicts. Voss2006 analyzed experts' protocols dealing with problem-solving.\nThe model has also been used in research on computer-supported collaborative learning. Erduran2004 adapt Toulmin's model for coding classroom argumentative discourse among teachers and students. Stegmann2011 builds on a simplified Toulmin's model for scripted construction of argument in computer-supported collaborative learning. Garcia-Mila2013 coded utterances into categories from Toulmin's model in persuasion and consensus-reaching among students. Weinberger.Fischer.2006 analyze asynchronous discussion boards in which learners engage in an argumentative discourse with the goal to acquire knowledge. For coding the argument dimension, they created a set of argumentative moves based on Toulmin's model. Given this empirical evidence, we decided to build upon the Toulmin's model.\nIn this annotation task, a sequence of tokens (e.g. a phrase, a sentence, or any arbitrary text span) is labeled with a corresponding argument component (such as the claim, the grounds, and others). There are no explicit relations between these annotation spans as the relations are implicitly encoded in the pragmatic function of the components in the Toulmin's model.\nIn order to prove the suitability of the Toulmin's model, we analyzed 40 random documents from the gold data persuasive dataset using the original Toulmin's model as presented in section SECREF21 . We took into account sever criteria for assessment, such as frequency of occurrence of the components or their importance for the task. We proposed some modifications of the model based on the following observations.\nAuthors do not state the degree of cogency (the probability of their claim, as proposed by Toulmin). Thus we omitted qualifier from the model due to its absence in the data.\nThe warrant as a logical explanation why one should accept the claim given the evidence is almost never stated. As pointed out by BIBREF37 , “data are appealed to explicitly, warrants implicitly.” This observation has also been made by Voss2006. Also, according to [p. 205]Eemeren.et.al.1987, the distinction of warrant is perfectly clear only in Toulmin’s examples, but the definitions fail in practice. We omitted warrant from the model.\nRebuttal is a statement that attacks the claim, thus playing a role of an opposing view. In reality, the authors often attack the presented rebuttals by another counter-rebuttal in order to keep the whole argument's position consistent. Thus we introduced a new component – refutation – which is used for attacking the rebuttal. Annotation of refutation was conditioned of explicit presence of rebuttal and enforced by the annotation guidelines. The chain rebuttal–refutation is also known as the procatalepsis figure in rhetoric, in which the speaker raises an objection to his own argument and then immediately answers it. By doing so, the speaker hopes to strengthen the argument by dealing with possible counter-arguments before the audience can raise them BIBREF43 .\nThe claim of the argument should always reflect the main standpoint with respect to the discussed controversy. We observed that this standpoint is not always explicitly expressed, but remains implicit and must be inferred by the reader. Therefore, we allow the claim to be implicit. In such a case, the annotators must explicitly write down the (inferred) stance of the author.\nBy definition, the Toulmin's model is intended to model single argument, with the claim in its center. However, we observed in our data, that some authors elaborate on both sides of the controversy equally and put forward an argument for each side (by argument here we mean the claim and its premises, backings, etc.). Therefore we allow multiple arguments to be annotated in one document. At the same time, we restrained the annotators from creating complex argument hierarchies.\nToulmin's grounds have an equivalent role to a premise in the classical view on an argument BIBREF15 , BIBREF60 in terms that they offer the reasons why one should accept the standpoint expressed by the claim. As this terminology has been used in several related works in the argumentation mining field BIBREF7 , BIBREF61 , BIBREF62 , BIBREF11 , we will keep this convention and denote the grounds as premises.\nOne of the main critiques of the original Toulmin's model was the vague distinction between grounds, warrant, and backing BIBREF63 , BIBREF64 , BIBREF65 . The role of backing is to give additional support to the warrant, but there is no warrant in our model anymore. However, what we observed during the analysis, was a presence of some additional evidence. Such evidence does not play the role of the grounds (premises) as it is not meant as a reason supporting the claim, but it also does not explain the reasoning, thus is not a warrant either. It usually supports the whole argument and is stated by the author as a certain fact. Therefore, we extended the scope of backing as an additional support to the whole argument.\nThe annotators were instructed to distinguish between premises and backing, so that premises should cover generally applicable reasons for the claim, whereas backing is a single personal experience or statements that give credibility or attribute certain expertise to the author. As a sanity check, the argument should still make sense after removing backing (would be only considered “weaker”).\nWe call the model as a modified Toulmin's model. It contains five argument components, namely claim, premise, backing, rebuttal, and refutation. When annotating a document, any arbitrary token span can be labeled with an argument component; the components do not overlap. The spans are not known in advance and the annotator thus chooses the span and the component type at the same time. All components are optional (they do not have to be present in the argument) except the claim, which is either explicit or implicit (see above). If a token span is not labeled by any argument component, it is not considered as a part of the argument and is later denoted as none (this category is not assigned by the annotators).\nAn example analysis of a forum post is shown in Figure FIGREF65 . Figure FIGREF66 then shows a diagram of the analysis from that example (the content of the argument components was shortened or rephrased).\nThe annotation experiment was split into three phases. All documents were annotated by three independent annotators, who participated in two training sessions. During the first phase, 50 random comments and forum posts were annotated. Problematic cases were resolved after discussion and the guidelines were refined. In the second phase, we wanted to extend the range of annotated registers, so we selected 148 comments and forum posts as well as 41 blog posts. After the second phase, the annotation guidelines were final.\nIn the final phase, we extended the range of annotated registers and added newswire articles from the raw corpus in order to test whether the annotation guidelines (and inherently the model) is general enough. Therefore we selected 96 comments/forum posts, 8 blog posts, and 8 articles for this phase. A detailed inter-annotator agreement study on documents from this final phase will be reported in section UID75 .\nThe annotations were very time-consuming. In total, each annotator spent 35 hours by annotating in the course of five weeks. Discussions and consolidation of the gold data took another 6 hours. Comments and forum posts required on average of 4 minutes per document to annotate, while blog posts and articles on average of 14 minutes per document. Examples of annotated documents from the gold data are listed in Appendix UID158 .\nWe discarded 11 documents out of the total 351 annotated documents. Five forum posts, although annotated as persuasive in the first annotation study, were at a deeper look a mixture of two or more posts with missing quotations, therefore unsuitable for analyzing argumentation. Three blog posts and two articles were found not to be argumentative (the authors took no stance to the discussed controversy) and one article was an interview, which the current model cannot capture (a dialogical argumentation model would be required).\nFor each of the 340 documents, the gold standard annotations were obtained using the majority vote. If simple majority voting was not possible (different boundaries of the argument component together with a different component label), the gold standard was set after discussion among the annotators. We will refer to this corpus as the gold standard Toulmin corpus. The distribution of topics and registers in this corpus in shown in Table TABREF71 , and Table TABREF72 presents some lexical statistics.\nBased on pre-studies, we set the minimal unit for annotation as token. The documents were pre-segmented using the Stanford Core NLP sentence splitter BIBREF69 embedded in the DKPro Core framework BIBREF70 . Annotators were asked to stick to the sentence level by default and label entire pre-segmented sentences. They should switch to annotations on the token level only if (a) a particular sentence contained more than one argument component, or (b) if the automatic sentence segmentation was wrong. Given the “noise” in user-generated Web data (wrong or missing punctuation, casing, etc.), this was often the case.\nAnnotators were also asked to rephrase (summarize) each annotated argument component into a simple statement when applicable, as shown in Figure FIGREF66 . This was used as a first sanity checking step, as each argument component is expected to be a coherent discourse unit. For example, if a particular occurrence of a premise cannot be summarized/rephrased into one statement, this may require further splitting into two or more premises.\nFor the actual annotations, we developed a custom-made web-based application that allowed users to switch between different granularity of argument components (tokens or sentences), to annotate the same document in different argument “dimensions” (logos and pathos), and to write summary for each annotated argument component.\nAs a measure of annotation reliability, we rely on Krippendorff's unitized alpha ( INLINEFORM0 ) BIBREF71 . To the best of our knowledge, this is the only agreement measure that is applicable when both labels and boundaries of segments are to be annotated.\nAlthough the measure has been used in related annotation works BIBREF61 , BIBREF7 , BIBREF72 , there is one important detail that has not been properly communicated. The INLINEFORM0 is computed over a continuum of the smallest units, such as tokens. This continuum corresponds to a single document in the original Krippendorff's work. However, there are two possible extensions to multiple documents (a corpus), namely (a) to compute INLINEFORM1 for each document first and then report an average value, or (b) to concatenate all documents into one large continuum and compute INLINEFORM2 over it. The first approach with averaging yielded extremely high the standard deviation of INLINEFORM3 (i.e., avg. = 0.253; std. dev. = 0.886; median = 0.476 for the claim). This says that some documents are easy to annotate while others are harder, but interpretation of such averaged value has no evidence either in BIBREF71 or other papers based upon it. Thus we use the other methodology and treat the whole corpus as a single long continuum (which yields in the example of claim 0.541 INLINEFORM4 ).\nTable TABREF77 shows the inter-annotator agreement as measured on documents from the last annotation phase (see section UID67 ). The overall INLINEFORM0 for all register types, topics, and argument components is 0.48 in the logos dimension (annotated with the modified Toulmin's model). Such agreement can be considered as moderate by the measures proposed by Landis.Koch.1977, however, direct interpretation of the agreement value lacks consensus BIBREF54 . Similar inter-annotator agreement numbers were achieved in the relevant works in argumentation mining (refer to Table TABREF33 in section SECREF31 ; although most of the numbers are not directly comparable, as different inter-annotator metrics were used on different tasks).\nThere is a huge difference in INLINEFORM0 regarding the registers between comments + forums posts ( INLINEFORM1 0.60, Table TABREF77 a) and articles + blog posts ( INLINEFORM2 0.09, Table TABREF77 b) in the logos dimension. If we break down the value with respect to the individual argument components, the agreement on claim and premise is substantial in the case of comments and forum posts (0.59 and 0.69, respectively). By contrast, these argument components were annotated only with a fair agreement in articles and blog posts (0.22 and 0.24, respectively).\nAs can be also observed from Table TABREF77 , the annotation agreement in the logos dimension varies regarding the document topic. While it is substantial/moderate for prayer in schools (0.68) or private vs. public schools (0.44), for some topics it remains rather slight, such as in the case of redshirting (0.14) or mainstreaming (0.08).\nFirst, we examine the disagreement in annotations by posing the following research question: are there any measurable properties of the annotated documents that might systematically cause low inter-annotator agreement? We use Pearson's correlation coefficient between INLINEFORM0 on each document and the particular property under investigation. We investigated the following set of measures.\nFull sentence coverage ratio represents a ratio of argument component boundaries that are aligned to sentence boundaries. The value is 1.0 if all annotations in the particular document are aligned to sentences and 0.0 if no annotations match the sentence boundaries. Our hypothesis was that automatic segmentation to sentences was often incorrect, therefore annotators had to switch to the token level annotations and this might have increased disagreement on boundaries of the argument components.\nDocument length, paragraph length and average sentence length. Our hypotheses was that the length of documents, paragraphs, or sentences negatively affects the agreement.\nReadability measures. We tested four standard readability measures, namely Ari BIBREF73 , Coleman-Liau BIBREF74 , Flesch BIBREF75 , and Lix BIBREF76 to find out whether readability of the documents plays any role in annotation agreement.\nCorrelation results are listed in Table TABREF82 . We observed the following statistically significant ( INLINEFORM0 ) correlations. First, document length negatively correlates with agreement in comments. The longer the comment was the lower the agreement was. Second, average paragraph length negatively correlates with agreement in blog posts. The longer the paragraphs in blogs were, the lower agreement was reached. Third, all readability scores negatively correlate with agreement in the public vs. private school domain, meaning that the more complicated the text in terms of readability is, the lower agreement was reached. We observed no significant correlation in sentence coverage and average sentence length measures. We cannot draw any general conclusion from these results, but we can state that some registers and topics, given their properties, are more challenging to annotate than others.\nAnother qualitative analysis of disagreements between annotators was performed by constructing a probabilistic confusion matrix BIBREF77 on the token level. The biggest disagreements, as can be seen in Table TABREF85 , is caused by rebuttal and refutation confused with none (0.27 and 0.40, respectively). This is another sign that these two argument components were very hard to annotate. As shown in Table TABREF77 , the INLINEFORM5 was also low – 0.08 for rebuttal and 0.17 for refutation.\nWe analyzed the annotations and found the following phenomena that usually caused disagreements between annotators.\nEach argument component (e.g., premise or backing) should express one consistent and coherent piece of information, for example a single reason in case of the premise (see Section UID73 ). However, the decision whether a longer text should be kept as a single argument component or segmented into multiple components is subjective and highly text-specific.\nWhile rhetorical questions have been researched extensively in linguistics BIBREF78 , BIBREF79 , BIBREF80 , BIBREF81 , their role in argumentation represents a substantial research question BIBREF82 , BIBREF83 , BIBREF84 , BIBREF85 , BIBREF86 . Teninbaum.2011 provides a brief history of rhetorical questions in persuasion. In short, rhetorical questions should provoke the reader. From the perspective of our argumentation model, rhetorical questions might fall both into the logos dimension (and thus be labeled as, e.g., claim, premise, etc.) or into the pathos dimension (refer to Section SECREF20 ). Again, the decision is usually not clear-cut.\nAs introduced in section UID55 , rebuttal attacks the claim by presenting an opponent's view. In most cases, the rebuttal is again attacked by the author using refutation. From the pragmatic perspective, refutation thus supports the author's stance expressed by the claim. Therefore, it can be easily confused with premises, as the function of both is to provide support for the claim. Refutation thus only takes place if it is meant as a reaction to the rebuttal. It follows the discussed matter and contradicts it. Such a discourse is usually expressed as:\n[claim: My claim.] [rebuttal: On the other hand, some people claim XXX which makes my claim wrong.] [refutation: But this is not true, because of YYY.]\nHowever, the author might also take the following defensible approach to formulate the argument:\n[rebuttal: Some people claim XXX-1 which makes my claim wrong.] [refutation: But this is not true, because of YYY-1.] [rebuttal: Some people claim XXX-2 which makes my claim wrong.] [refutation: But this is not true, because of YYY-2.] [claim: Therefore my claim.]\nIf this argument is formulated without stating the rebuttals, it would be equivalent to the following:\n[premise: YYY-1.] [premise: YYY-2.] [claim: Therefore my claim.]\nThis example shows that rebuttal and refutation represent a rhetorical device to produce arguments, but the distinction between refutation and premise is context-dependent and on the functional level both premise and refutation have very similar role – to support the author's standpoint. Although introducing dialogical moves into monological model and its practical consequences, as described above, can be seen as a shortcoming of our model, this rhetoric figure has been identified by argumentation researchers as procatalepsis BIBREF43 . A broader view on incorporating opposing views (or lack thereof) is discussed under the term confirmation bias by BIBREF21 who claim that “[...] people are trying to convince others. They are typically looking for arguments and evidence to confirm their own claim, and ignoring negative arguments and evidence unless they anticipate having to rebut them.” The dialectical attack of possible counter-arguments may thus strengthen one's own argument.\nOne possible solution would be to refrain from capturing this phenomena completely and to simplify the model to claims and premises, for instance. However, the following example would then miss an important piece of information, as the last two clauses would be left un-annotated. At the same time, annotating the last clause as premise would be misleading, because it does not support the claim (in fact, it supports it only indirectly by attacking the rebuttal; this can be seen as a support is considered as an admissible extension of abstract argument graph by BIBREF87 ).\nDoc#422 (forumpost, homeschooling) [claim: I try not to be anti-homeschooling, but... it's just hard for me.] [premise: I really haven't met any homeschoolers who turned out quite right, including myself.] I apologize if what I'm saying offends any of you - that's not my intention, [rebuttal: I know that there are many homeschooled children who do just fine,] but [refutation: that hasn't been my experience.]\nTo the best of our knowledge, these context-dependent dialogical properties of argument components using Toulmin's model have not been solved in the literature on argumentation theory and we suggest that these observations should be taken into account in the future research in monological argumentation.\nAppeal to emotion, sarcasm, irony, or jokes are common in argumentation in user-generated Web content. We also observed documents in our data that were purely sarcastic (the pathos dimension), therefore logical analysis of the argument (the logos dimension) would make no sense. However, given the structure of such documents, some claims or premises might be also identified. Such an argument is a typical example of fallacious argumentation, which intentionally pretends to present a valid argument, but its persuasion is conveyed purely for example by appealing to emotions of the reader BIBREF88 .\nWe present some statistics of the annotated data that are important from the argumentation research perspective. Regardless of the register, 48% of claims are implicit. This means that the authors assume that their standpoint towards the discussed controversy can be inferred by the reader and give only reasons for that standpoint. Also, explicit claims are mainly written just once, only in 3% of the documents the claim was rephrased and occurred multiple times.\nIn 6% of the documents, the reasons for an implicit claim are given only in the pathos dimension, making the argument purely persuasive without logical argumentation.\nThe “myside bias”, defined as a bias against information supporting another side of an argument BIBREF89 , BIBREF90 , can be observed by the presence of rebuttals to the author's claim or by formulating arguments for both sides when the overall stance is neutral. While 85% of the documents do not consider any opposing side, only 8% documents present a rebuttal, which is then attacked by refutation in 4% of the documents. Multiple rebuttals and refutations were found in 3% of the documents. Only 4% of the documents were overall neutral and presented arguments for both sides, mainly in blog posts.\nWe were also interested whether mitigating linguistic devices are employed in the annotated arguments, namely in their main stance-taking components, the claims. Such devices typically include parenthetical verbs, syntactic constructions, token agreements, hedges, challenge questions, discourse markers, and tag questions, among others BIBREF91 . In particular, [p. 1]Kaltenbock.et.al.2010 define hedging as a discourse strategy that reduces the force or truth of an utterance and thus reduces the risk a speaker runs when uttering a strong or firm assertion or other speech act. We manually examined the use of hedging in the annotated claims.\nOur main observation is that hedging is used differently across topics. For instance, about 30-35% of claims in homeschooling and mainstreaming signal the lack of a full commitment to the expressed stance, in contrast to prayer in schools (15%) or public vs. private schools (about 10%). Typical hedging cues include speculations and modality (“If I have kids, I will probably homeschool them.”), statements as neutral observations (“It's not wrong to hold the opinion that in general it's better for kids to go to school than to be homeschooled.”), or weasel phrases BIBREF92 (“In some cases, inclusion can work fantastically well.”, “For the majority of the children in the school, mainstream would not have been a suitable placement.”).\nOn the other hand, most claims that are used for instance in the prayer in schools arguments are very direct, without trying to diminish its commitment to the conveyed belief (for example, “NO PRAYER IN SCHOOLS!... period.”, “Get it out of public schools”, “Pray at home.”, or “No organized prayers or services anywhere on public school board property - FOR ANYONE.”). Moreover, some claims are clearly offensive, persuading by direct imperative clauses towards the opponents/audience (“TAKE YOUR KIDS PRIVATE IF YOU CARE AS I DID”, “Run, don't walk, to the nearest private school.”) or even accuse the opponents for taking a certain stance (“You are a bad person if you send your children to private school.”).\nThese observations are consistent with the findings from the first annotation study on persuasion (see section UID48 ), namely that some topics attract heated argumentation where participant take very clear and reserved standpoints (such as prayer in schools or private vs. public schools), while discussions about other topics are rather milder. It has been shown that the choices a speaker makes to express a position are informed by their social and cultural background, as well as their ability to speak the language BIBREF93 , BIBREF94 , BIBREF91 . However, given the uncontrolled settings of the user-generated Web content, we cannot infer any similar conclusions in this respect.\nWe investigated premises across all topics in order to find the type of support used in the argument. We followed the approach of Park.Cardie.2014, who distinguished three types of propositions in their study, namely unverifiable, verifiable non-experiential, and verifiable experiential.\nVerifiable non-experiential and verifiable experiential propositions, unlike unverifiable propositions, contain an objective assertion, where objective means “expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations.” Such assertions have truth values that can be proved or disproved with objective evidence; the correctness of the assertion or the availability of the objective evidence does not matter BIBREF8 . A verifiable proposition can further be distinguished as experiential or not, depending on whether the proposition is about the writer's personal state or experience or something non-experiential. Verifiable experiential propositions are sometimes referred to as anectotal evidence, provide the novel knowledge that readers are seeking BIBREF8 .\nTable TABREF97 shows the distribution of the premise types with examples for each topic from the annotated corpus. As can be seen in the first row, arguments in prayer in schools contain majority (73%) of unverifiable premises. Closer examination reveals that their content vary from general vague propositions to obvious fallacies, such as a hasty generalization, straw men, or slippery slope. As Nieminen.Mustonen.2014 found out, fallacies are very common in argumentation about religion-related issues. On the other side of the spectrum, arguments about redshirting rely mostly on anecdotal evidence (61% of verifiable experiential propositions). We will discuss the phenomena of narratives in argumentation in more detail later in section UID98 . All the topics except private vs. public schools exhibit similar amount of verifiable non-experiential premises (9%–22%), usually referring to expert studies or facts. However, this type of premises has usually the lowest frequency.\nManually analyzing argumentative discourse and reconstructing (annotating) the underlying argument structure and its components is difficult. As [p. 267]Reed2006 point out, “the analysis of arguments is often hard, not only for students, but for experts too.” According to [p. 81]Harrell.2011b, argumentation is a skill and “even for simple arguments, untrained college students can identify the conclusion but without prompting are poor at both identifying the premises and how the premises support the conclusion.” [p. 81]Harrell.2011 further claims that “a wide literature supports the contention that the particular skills of understanding, evaluating, and producing arguments are generally poor in the population of people who have not had specific training and that specific training is what improves these skills.” Some studies, for example, show that students perform significantly better on reasoning tasks when they have learned to identify premises and conclusions BIBREF95 or have learned some standard argumentation norms BIBREF96 .\nOne particular extra challenge in analyzing argumentation in Web user-generated discourse is that the authors produce their texts probably without any existing argumentation theory or model in mind. We assume that argumentation or persuasion is inherent when users discuss controversial topics, but the true reasons why people participate in on-line communities and what drives their behavior is another research question BIBREF97 , BIBREF98 , BIBREF99 , BIBREF100 . When the analyzed texts have a clear intention to produce argumentative discourse, such as in argumentative essays BIBREF7 , the argumentation is much more explicit and a substantially higher inter-annotator agreement can be achieved.\nThe model seems to be suitable for short persuasive documents, such as comments and forum posts. Its applicability to longer documents, such as articles or blog posts, is problematic for several reasons.\nThe argument components of the (modified) Toulmin's model and their roles are not expressive enough to capture argumentation that not only conveys the logical structure (in terms of reasons put forward to support the claim), but also relies heavily on the rhetorical power. This involves various stylistic devices, pervading narratives, direct and indirect speech, or interviews. While in some cases the argument components are easily recognizable, the vast majority of the discourse in articles and blog posts does not correspond to any distinguishable argumentative function in the logos dimension. As the purpose of such discourse relates more to rhetoric than to argumentation, unambiguous analysis of such phenomena goes beyond capabilities of the current argumentation model. For a discussion about metaphors in Toulmin's model of argumentation see, e.g., BIBREF102 , BIBREF103 .\nArticles without a clear standpoint towards the discussed controversy cannot be easily annotated with the model either. Although the matter is viewed from both sides and there might be reasons presented for either of them, the overall persuasive intention is missing and fitting such data to the argumentation framework causes disagreements. One solution might be to break the document down to paragraphs and annotate each paragraph separately, examining argumentation on a different level of granularity.\nAs introduced in section SECREF20 , there are several dimensions of an argument. The Toulmin's model focuses solely on the logos dimension. We decided to ignore the ethos dimension, because dealing with the author's credibility remains unclear, given the variety of the source web data. However, exploiting the pathos dimension of an argument is prevalent in the web data, for example as an appeal to emotions. Therefore we experimented with annotating appeal to emotions as a separate category independent of components in the logos dimension. We defined some features for the annotators how to distinguish appeal to emotions. Figurative language such as hyperbole, sarcasm, or obvious exaggerating to “spice up” the argument are the typical signs of pathos. In an extreme case, the whole argument might be purely emotional, as in the following example.\nDoc#1698 (comment, prayer in schools) [app-to-emot: Prayer being removed from school is just the leading indicator of a nation that is ‘Falling Away’ from Jehovah. [...] And the disasters we see today are simply God’s finger writing on the wall: Mene, mene, Tekel, Upharsin; that is, God has weighed America in the balances, and we’ve been found wanting. No wonder 50 million babies have been aborted since 1973. [...]]\nWe kept annotations on the pathos dimension as simple as possible (with only one appeal to emotions label), but the resulting agreement was unsatisfying ( INLINEFORM0 0.30) even after several annotation iterations. Appeal to emotions is considered as a type of fallacy BIBREF104 , BIBREF18 . Given the results, we assume that more carefully designed approach to fallacy annotation should be applied. To the best of our knowledge, there have been very few research works on modeling fallacies similarly to arguments on the discourse level BIBREF105 . Therefore the question, in which detail and structure fallacies should be annotated, remains open. For the rest of the paper, we thus focus on the logos dimension solely.\nSome of the educational topics under examination relate to young children (e.g., redshirting or mainstreaming); therefore we assume that the majority of participants in discussions are their parents. We observed that many documents related to these topics contain narratives. Sometimes the story telling is meant as a support for the argument, but there are documents where the narrative has no intention to persuade and is simply a story sharing.\nThere is no widely accepted theory of the role of narratives among argumentation scholars. According to Fisher.1987, humans are storytellers by nature, and the “reason” in argumentation is therefore better understood in and through the narratives. He found that good reasons often take the form of narratives. Hoeken.Fikkers.2014 investigated how integration of explicit argumentative content into narratives influences issue-relevant thinking and concluded that identifying with the character being in favor of the issue yielded a more positive attitude toward the issue. In a recent research, Bex.2011 proposes an argumentative-narrative model of reasoning with evidence, further elaborated in BIBREF106 ; also Niehaus.et.al.2012 proposes a computational model of narrative persuasion.\nStemming from another research field, LeytonEscobar2014 found that online community members who use and share narratives have higher participation levels and that narratives are useful tools to build cohesive cultures and increase participation. Betsch.et.al.2010 examined influencing vaccine intentions among parents and found that narratives carry more weight than statistics.\nThe annotation experiment was split into three phases.",

As president of the SCLC, he led the unsuccessful Albany Movement in Albany, Georgia, and helped organize some of the nonviolent 1963 protests in Birmingham, Alabama. King was one of the leaders of the 1963 March on Washington, where he delivered his \"I Have a Dream\" speech on the steps of the Lincoln Memorial. The civil rights movement achieved pivotal legislative gains in the Civil Rights Act of 1964, Voting Rights Act of 1965, and the Fair Housing Act of 1968.\n\nThe SCLC put into practice the tactics of nonviolent protest with some success by strategically choosing the methods and places in which protests were carried out. There were several dramatic standoffs with segregationist authorities, who frequently responded violently. King was jailed several times. Federal Bureau of Investigation (FBI) director J. Edgar Hoover considered King a radical and made him an object of the FBI's COINTELPRO from 1963 forward. FBI agents investigated him for possible communist ties, spied on his personal life, and secretly recorded him. In 1964, the FBI mailed King a threatening anonymous letter, which he interpreted as an attempt to make him commit suicide.\n\nOn October 14, 1964, King won the Nobel Peace Prize for combating racial inequality through nonviolent resistance. In 1965, he helped organize two of the three Selma to Montgomery marches. In his final years, he expanded his focus to include opposition towards poverty, capitalism, and the Vietnam War. In 1968, King was planning a national occupation of Washington, D.C., to be called the Poor People's Campaign, when he was assassinated on April 4 in Memphis, Tennessee. His death was followed by national mourning, as well as anger leading to riots in many U.S. cities. King was posthumously awarded the Presidential Medal of Freedom in 1977 and the Congressional Gold Medal in 2003. Martin Luther King Jr. Day was established as a holiday in cities and states throughout the United States beginning in 1971; the federal holiday was first observed in 1986. Hundreds of streets in the U.S. have been renamed in his honor, and King County in Washington was rededicated for him. The Martin Luther King Jr. Memorial on the National Mall in Washington, D.C., was dedicated in 2011.",

        "question": "How do UK telephone numbers work?",
        "evidence": "",
        "answer": "The UK telephone numbering system has a strange and complicated pattern which is born out of many historical changes and anomalies. Essentially nearly all numbers start with 0 when dialled in the UK. The leading 0 is omitted when calling from overseas and the prefix \"+44\" is added in its place. The second digit indicates what type of number it is. So called geographic numbers (those associated with an area code) start with 01or 02. Numbers starting with 03 are not associated with any area code but are charged at the same rates as numbers beginning with 01 or 02. Mobile numbers always start with 07. Numbers starting 09 are premium rate numbers which incur high charges for providing additional services.  Numbers starting with 080 are toll free. Other numbers starting with 08 are charged at special rates but not the very high rates for 09 numbers.\n\nSpecial numbers that do not start with 0 include 999 and 112 for emergencies, 101 for non emergency Police matters, 111 for contacting the National Health Service in a non emergency and directory enquiries services that start with 118.\n\nThe history of UK area codes (beginning 01 and 02) dates back to the times when individual telephone exchanges had their own one, two or three character Subscriber Trunk Dialing (STD) codes (e.g. B for Birmingham or AY6 for Aylesbury). in 1966 STD codes were converted to numbers using the number patterns on telephone dials (where 2=ABC, 3 = DEF etc.) so Birmingham became 021, Aylesbury became 0296. 01 was the code allocated to London. Area codes were between 2 and five characters long including the leading zero. Following the area code a local number of between 3 and 7 digits was added for each line to make the complete number either 9 or 10 digits long. Callers within the same area code could dial other lines with the same code by simply dialling the local number omitting the area code. In 1968 area codes beginning 00 were moved to free up 00 for other uses.\n\nBy the 1980s a number of factors meant that some areas, especially London, were running out of codes. Various measures were introduced including, in 1990,  the splitting of London into 071 (inner London) and 081 (outer London).\n\nThe 80s and 90s also saw the gradual introduction of \"non geographic\" numbers e.g. the toll free 0800 numbers and a number of patterns for emerging mobile services. Premium rate services were also launched using 0898.\n\nIn 1995 on so called \"phONEday\" a leading 1 was added after the zero. London numbers became either 0171 or 0181, Birmingham 0121, Aylesbury 01296 etc.\n\nThis established the pattern we see today allowing for some area codes to move to \"02\" codes over the next few years. In addition larger cities were allocated new codes beginning 011 e.g. 0113 for Leeds, 0117 for Bristol.\n\nIn 2000 the \"big number change\" saw London codes changed yet again = 0171 became 020 7 and 0181 became 020 8 allowing for new London numbers to be issued starting with 020 3 and 020 4 . Other cities that gained \"02\" style codes were Southampton/Portsmouth 023 , Coventry 024 and Cardiff 029.  A unified code of 028 was introduced in Northern Ireland.",

This alignment mechanism is difficult to accomplish in models where text sequences are first embedded into a common space and then compared in pairs BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 .\nWe propose to learn a semantic-aware Network Embedding (NE) that incorporates word-level alignment features abstracted from text sequences associated with vertex pairs.

These features are then accumulated via a simple but efficient aggregation function, obtaining the final representation for the sentence. As a result, the word-by-word alignment features (as illustrated in Figure 1 ) are explicitly and effectively captured by our model. Further, the learned network embeddings under our framework are adaptive to the specific (local) vertices that are considered, and thus are context-aware and especially suitable for downstream tasks, such as link prediction. Moreover, since the word-by-word matching procedure introduced here is highly parallelizable and does not require any complex encoding networks, such as Long Short-Term Memory (LSTM) or Convolutional Neural Networks (CNNs), our framework requires significantly less time for training, which is attractive for large-scale network applications.\nHowever, as shown in Figure 1 , to assess the similarity between two research papers, a more effective strategy would compare and align (via local-weighting) individual important words (keywords) within a pair of abstracts, while information from other words (e.g., stop words) that tend to be less relevant can be effectively ignored (down-weighted). \nWe propose to learn a semantic-aware Network Embedding (NE) that incorporates word-level alignment features abstracted from text sequences associated with vertex pairs.

In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nIn this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task.",

Cards with kings, queens, or jacks count are considered to have.a value of 10. Cards with an ace can be considered to be either a 1 or 11, whichever benefits the player. The player has the choice to take one additional card at a time to increase their value, until their choose to stop and \"stay\", or lose the game if their cards total more than 21. Once the player chooses to \"stay\", the dealer goes through a similar process by taking new cards until they either go over 21 and lose, or reach 17, 18, 19, 20, or 21. The player wins if the sum of the value of their cards  is greater than the sum of the value of the dealer's card.

        "evidence": "From the definitions of `explainable AI' and `context understanding,' in the previous section, we can derive the following corollary:\nThe explainability of AI algorithms is related to how context is processed, computationally, based on the machine's perceptual capabilities and on the external knowledge resources that are available.\nAlong this direction, the remainder of this chapter explores two concrete scenarios of context understanding, realized by neuro-symbolic architectures|i.e., hybrid AI frameworks that instruct machine perception (based on deep neural networks) with knowledge graphs. These examples were chosen to illustrate the general applicability of neuro-symbolism and its relevance to contemporary research problems.\nSpecifically, section SECREF3 considers context understanding for autonomous vehicles: we describe how a knowledge graph can be built from a dataset of urban driving situations and how this knowledge graph can be translated into a continuous vector-space representation. This embedding space can be used to estimate the semantic similarity of visual scenes by using neural networks as powerful, non-linear function approximators. Here, models may be trained to make danger assessments of the visual scene and, if necessary, transfer control to the human in complex scenarios. The ability to make this assessment is an important capability for autonomous vehicles, when we consider the negative ramifications for a machine to remain invariant to changing weather conditions, anomalous behavior of dynamic obstacles on the road (e.g., other vehicles, pedestrians), varied lighting conditions, and other challenging circumstances. We suggest neuro-symbolic fusion as one solution and, indeed, our results show that our embedding space preserves the semantic properties of the conceptual elements that make up visual scenes.\nIn section SECREF17, we describe context understanding for language tasks. Here, models are supplied with three separate modalities: external commonsense knowledge, unstructured textual context, and a series of answer candidates. In this task, models are tested on their ability to fuse together these disparate sources of information for making the appropriate logical inferences. We designed methods to extract adequate semantic structures (i.e., triples) from two comprehensive commonsense knowledge graphs, ConceptNet BIBREF6 and Atomic BIBREF7, and to inject this external context into language models. In general, open-domain linguistic context is useful for different tasks in Natural Language Processing (NLP), including: information-extraction, text-classification, extractive and abstractive summarization, and question-answering (QA). For ease of quantitative evaluation, we consider a QA task in section SECREF17. In particular, the task is to select the correct answer from a pool of candidates, given a question that specifically requires commonsense to resolve. For example, the question, If electrical equipment won't power on, what connection should be checked? is associated with `company', `airport', `telephone network', `wires', and `freeway'(where `wires' is the correct answer choice). We demonstrate that our proposed hybrid architecture out-performs the state-of-the-art neural approaches that do not utilize structured commonsense knowledge bases. Furthermore, we discuss how our approach maintains explainability in the model's decision-making process: the model has the joint task of learning an attention distribution over the commonsense knowledge context which, in turn, depends on the knowledge triples that were conceptually most salient for selecting the correct answer candidate, downstream. Fundamentally, the goal of this project is to make human interaction with chatbots and personal assistants more robust. For this to happen, it is crucial to equip intelligent agents with a shared understanding of general contexts, i.e., commonsense. Conventionally, machine commonsense had been computationally articulated using symbolic languages|Cyc being one of the most prominent outcomes of this approach BIBREF8. However, symbolic commonsense representations are neither scalable nor comprehensive, as they depend heavily on the knowledge engineering experts that encode them. In this regard, the advent of deep learning and, in particular, the possibility of fusing symbolic knowledge into sub-symbolic (neural) layers, has recently led to a revival of this AI research topic.\nSpecifically, section SECREF3 considers context understanding for autonomous vehicles: we describe how a knowledge graph can be built from a dataset of urban driving situations and how this knowledge graph can be translated into a continuous vector-space representation.",

For the CNN-based framework, we use a softmax function in the output layer for classification as described in Section SECREF9 .\nFor our single-label topic classification experiments, we use the Switchboard Telephone Speech Corpus BIBREF21 , a collection of two-sided telephone conversations. We use the same development (dev) and evaluation (eval) data sets as in BIBREF8 , BIBREF9 . Each whole conversation has two sides and one single topic, and topic ID is performed on each individual-side speech (i.e., each side is seen as one single spoken document). In the 35.7 hour dev data, there are 360 conversation sides evenly distributed across six different topics (recycling, capital punishment, drug testing, family finance, job benefits, car buying), i.e., each topic has equal number of 60 sides. In the 61.6 hour eval data, there are another different six topics (family life, news media, public education, exercise/fitness, pets, taxes) evenly distributed across 600 conversation sides. Algorithm design choices are explored through experiments on dev data. We use manual segmentations provided by the Switchboard corpus to produce utterances with speech activity, and UTD and AUD are operating only on those utterances.\nFor UTD, we use the ZRTools BIBREF7 implementation with the default parameters except that, we use cosine similarity threshold INLINEFORM0 , and vary the diagonal median filter duration INLINEFORM1 over INLINEFORM2 ; we try both the exact DTW-based similarity and the rescored similarity as described in Section SECREF1 , and tune the similarity threshold (used to partition the graph edges) over INLINEFORM3 . For AUD, the unsupervised training is performed only on the dev data (10 iterations); after training, we use the learned models to decode both dev and eval data set, and obtain the acoustic unit tokenizations. We use truncation level 200, which implies maximum 200 different acoustic units can be learned from the corpus. For each acoustic unit, we use a 3-state HMM with 2 Gaussians per state. For the stick-breaking construction of Dirichlet process, we vary the concentration parameter INLINEFORM4 over INLINEFORM5 , and other hyperparameters are the same as BIBREF10 . The acoustic features on which UTD and AUD operate are extracted using the same multilingual bottleneck (BN) network as described in BIBREF9 with Kaldi toolkit BIBREF22 . We conduct the multilingual BN training with 10 language collections (Assamese, Bengali, Cantonese, Haitian, Lao, Pashto, Tamil, Tagalog, Vietnamese and Zulu) – 10 hours of transcribed speech per language. Complete specifications can be found in BIBREF9 .\nFor SVM-based classification, we use the bag of discovered term unigrams, or bag of acoustic unit trigrams. On dev data, we try using the features of raw counts or scaled by IDF, SVM regularization tuned over INLINEFORM0 / INLINEFORM1 norm, regularization constant tuned over INLINEFORM2 , and SGD epochs tuned over INLINEFORM3 . We further normalize each feature to INLINEFORM4 norm unit length. Each experiment is a run of 10-fold cross validation (CV) on the 360 conversation sides of dev data, or on the 600 sides of eval data, respectively. Note that our data size here is relatively small (only 360 or 600) and the SGD training may give high variance in the performance BIBREF23 . Therefore, to report classification accuracy for each configuration (when varying features or models), we repeat each CV experiment 5 times, where each experiment again is a run of 10-fold CV; then for each configuration, the mean and standard deviation of 5 experiments is reported.\nFor CNN-based classification, we use the same strategy to report classification accuracy, i.e., repeating experiments 5 times (where each time is a 10-fold CV) for each CNN configuration. Note that the respective 10 folds of both dev and eval data sets are fixed the same for all the SVM and CNN experiments. Additionally, for each 10-fold CV experiment, instead of training on 9 folds and testing on the remaining 1 fold as in SVM, we use 8 folds for CNN training, leave another 1 fold out as validation data; after training each CNN model for up to 100 epochs, the model with the best accuracy on the validation data is used for evaluation on the test set. The acoustic unit sequence (as CNN inputs) are zero-padded to the longest length in each dataset. We implemented the CNNs in Keras BIBREF24 with Theano BIBREF25 backend. CNN architectures are determined through experiments on dev data. For SGD training we use the Adadelta optimizer BIBREF26 and mini-batch size 18. The INLINEFORM0 -gram window size of each convolutional feature transform INLINEFORM1 is 7. The size of each hidden feature vector INLINEFORM2 (extracted from the transform INLINEFORM3 ) is 1024, with rectified linear unit (ReLU) nonlinearities. Thus, after max-pooling over time, we have a 1024-dimensional vector again, which then goes through another hidden layer INLINEFORM4 (also set as 1024-dimensional with ReLU) and finally into a softmax. Dropout BIBREF27 rate 0.2 is used at each layer.\nWhen we initialize the vector representation of each acoustic unit with a set of pre-trained vectors (instead of random initializations), we apply the skip-gram model of word2vec BIBREF18 to the acoustic unit tokenizations of each data set. We use the gensim implementation BIBREF28 , which includes a vector space of embedding dimension 50 (tuned over INLINEFORM0 ), a skip-gram window of size 5, and SGD over 20 epochs.\nTable TABREF15 shows the topic ID results on Switchboard. For UTD-based classifications, we find that the default rescoring in ZRTools BIBREF7 which is designed to filter out the filled pauses produces comparable performance to the raw DTW similarity scores, but the rescoring can result in much faster connected-component clustering (Section SECREF1 ). Note that this rescoring model is estimated using a portion of transcribed Switchboard, but it is still a legitimate language-independent UTD approach while operating on languages other than English. While a diagonal median filter duration INLINEFORM0 of INLINEFORM1 or INLINEFORM2 gives similar results, INLINEFORM3 produces longer but fewer terms, giving more sparse feature representations. Therefore, we proceed with rescoring and INLINEFORM4 in the following UTD experiments (Section SECREF16 ).\nFor AUD-based classifications, CNN without word2vec pre-training usually gives comparable results with SVM; however, using word2vec pre-training, CNN substantially outperforms the competing SVM in all cases. Also as the concentration parameter INLINEFORM0 in AUD increases from INLINEFORM1 to INLINEFORM2 (yielding less concentrated distributions), we have more unique acoustic units in the tokenizations of both data sets, from 184 to 199, and INLINEFORM3 usually produces better results than INLINEFORM4 .\nFor the CNN-based framework, we use a softmax function in the output layer for classification as described in Section 3.2.",

        "answer": "Because it combines in one single value all the four indicators that are generally implied for evaluating the classifier performance (i.e., number of True Positives, False Positives, True Negatives and False Negatives).",
        "evidence": "Table 5 shows the results of our multi-class classification. For each of the classes, we have computed the ROC Area and F-Measure metrics BIBREF19 . The latter, in particular, is usually considered a significant metric in terms of classification, since it combines in one single value all the four indicators that are generally implied for evaluating the classifier performance (i.e., number of True Positives, False Positives, True Negatives and False Negatives). In our scenario, the meaning of the indicators, for each class, are as follows:\nTrue Positives are the articles classified as belonging to a certain class, that indeed belong to that class (according to the quality ratings given by the WikiProject Medicine);\nTrue Negatives are the articles classified as not belonging to a certain class, that indeed do not belong to that class;\nFalse Positives are the articles classified as belonging to a certain class, that do not belong to that class;\nFalse Negatives are the articles classified as not belonging to a certain class, that instead belong to that class.\nAt a first glance, we observe that, across all the models, the articles with the lowest classification values, for both ROC and F-Measure, are those labeled C and GA. Adding the Domain Informativeness feature produces a classification, which is slightly worse for C and FA articles, but better for the other four classes. This is particularly evident for the F-Measure of the articles of the GA class. A noticeable major improvement is obtained with the introduction of the features InfoBoxNormSize and Category in the Medical Domain model. The ROC Area increases for the articles of all the classes within the Full Medical Domain, while the F-Measure is always better than the Baseline and almost always better than the Medical Domain.\nThe size of an article, expressed either as the word count, analyzed in BIBREF20 , or as the article length, as done here, appears a very strong feature, able to discriminate the articles belonging to the highest and lowest quality classes. This is testified also by the results achieved exploiting the baseline model of BIBREF7 , which poorly succeeds in discriminating the articles of the intermediate quality classes, while achieving good results for Stub and FA. Here, the newly introduced features have a predominant effect on the articles of the highest classes. This could be justified by the fact that those articles contain, on average, more text and, then, NLP-based features can exploit more words belonging to a specific domain.\nThen, we observe that the ROC Area and the F-Measure are not tightly coupled (namely: high values for the first metric can correspond to low values for the second one, see for example C and GA): this is due to the nature of the ROC Area, that is affected by the different sizes of the considered classes. As an example, we can observe that the baseline model has the same ROC Area value for the articles of both class B and class GA, while the F-Measure of articles of class B is 0.282 higher than that of class GA.\nFinally, the results confirm that the adoption of domain-based features and, in general, of features that leverage NLP, help to distinguish between articles in the lowest classes and articles in the highest classes, as highlighted in bold in Table 5 . We notice also that exploiting the full medical domain leads us to the achievement of the best results.\nEven if preliminary, we believe that the results are promising and call both for features' further refinement and novel features, able to discriminate among the intermediate classes too.\nThe latter, in particular, is usually considered a significant metric in terms of classification, since it combines in one single value all the four indicators that are generally implied for evaluating the classifier performance (i.e., number of True Positives, False Positives, True Negatives and False Negatives).",

        "evidence": "We aimed to mimic the presence of sparse/noisy content distribution, mandating the need to curate a novel dataset via specific lexicons. We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation. With increasing the number of iterations, the pool of seed phrases gets refined and augments the selection of transport relevant tweets.

        "answer": "To further incorporating the document-level knowledge, NSP and PSP are extended with non-successive sentences, where the label smoothing technique is adopted.",
        "evidence": "The ability of semantic reasoning is essential for advanced natural language understanding (NLU) systems. Many NLU tasks that take sentence pairs as input, such as natural language inference (NLI) and machine reading comprehension (MRC), heavily rely on the ability of sophisticated semantic reasoning. For instance, the NLI task aims to determine whether the hypothesis sentence (e.g., a woman is sleeping) can be inferred from the premise sentence (e.g., a woman is talking on the phone). This requires the model to read and understand sentence pairs to make the specific semantic inference.\nBidirectional Encoder Representations from Transformer (BERT) BIBREF1 has shown strong ability in semantic reasoning. It was recently proposed and obtained impressive results on many tasks, ranging from text classification, natural language inference, and machine reading comprehension. BERT achieves this by employing two objectives in the pre-training, i.e., the masked language modeling (Masked LM) and the next sentence prediction (NSP). Intuitively, the Masked LM task concerns word-level knowledge, and the NSP task captures the global document-level information. The goal of NSP is to identify whether an input sentence is next to another input sentence. From the ablation study BIBREF1, the NSP task is quite useful for the downstream NLI and MRC tasks (e.g., +3.5% absolute gain on the Question NLI (QNLI) BIBREF2 task).\nDespite its usefulness, we suggest that BERT has not made full use of the document-level knowledge. The sentences in the negative samples used in NSP are randomly drawn from other documents. Therefore, to discriminate against these sentences, BERT is prone to aggregating the shallow semantic, e.g., topic, neglecting context clues useful for detailed reasoning. In other words, the canonical NSP task would encourage the model to recognize the correlation between sentences, rather than obtaining the ability of semantic entailment. This setting weakens the BERT model from learning specific semantic for inference. Another issue that renders NSP less effective is that BERT is order-sensitive. Performance degradation was observed on typical NLI tasks when the order of two input sentences are reversed during the BERT fine-tuning phase. It is reasonable as the NSP task can be roughly analogy to the NLI task when the input comes as (premise, hypothesis), considering the causal order among sentences. However, this identity between NSP and NLI is compromised when the sentences are swapped.\nBased on these considerations, we propose a simple yet effective method, i.e., introducing a IsPrev category to the classification task, which is a symmetric label of IsNext of NSP. The input of samples with IsPrev is the reverse of those with IsNext label. The advantages of using this previous sentence prediction (PSP) are three folds. (1) Learning the contrast between NSP and PSP forces the model to extract more detailed semantic, thereby the model is more capable of discriminating the correlation and entailment. (2) NSP and PSP are symmetric. This symmetric regularization alleviates the influence of the order of the input pair. (3) Empirical results indicate that our method is beneficial for all the semantic reasoning tasks that take sentence pair as input.\nIn addition, to further incorporating the document-level knowledge, NSP and PSP are extended with non-successive sentences, where the label smoothing technique is adopted. The proposed method yields a considerable improvement in our experiments. We evaluate the ability of semantic reasoning on standard NLI and MRC benchmarks, including the challenging HANS dataset BIBREF0. Analytical work on the HANS dataset provides a more comprehensible perspective towards the proposed method. Furthermore, the results on the Chinese benchmarks are provided to demonstrate its generality.\nIn summary, this work makes the following contributions:\nThe supervision signal from the original NSP task is weak for semantic inference. Therefore, a novel method is proposed to remedy the asymmetric issue and enhance the reasoning ability.\nBoth empirical and analytical evaluations are provided on the NLI and MRC datasets, which verifies the effectiveness of using more document-level knowledge.\nIn addition, to further incorporating the document-level knowledge, NSP and PSP are extended with non-successive sentences, where the label smoothing technique is adopted.",

        "question": "Which two datasets were used in the experiment?",
        "answer": "Gigaword and CNN",
        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths.",

        "answer": "The Great Depression (1929–1939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century.\n\nBetween 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and in some countries rose as high as 33%.",

As the figure shows, sports and politics are most dominant for offensive language including vulgar and hate speech. As for dialect, we looked at MSA and four major dialects, namely Egyptian (EGY), Leventine (LEV), Maghrebi (MGR), and Gulf (GLF). Figure FIGREF14 shows that 71% of vulgar tweets were written in EGY followed by GLF, which accounted for 13% of vulgar tweets. MSA was not used in any of the vulgar tweets. As for offensive tweets in general, EGY and GLF were used in 36% and 35% of the offensive tweets respectively. Unlike the case of vulgar language where MSA was non-existent, 15% of the offensive tweets were in fact written in MSA. For hate speech, GLF and EGY were again dominant and MSA consistuted 21% of the tweets. This is consistent with findings for other languages such as English and Italian where vulgar language was more frequently associated with colloquial language BIBREF24, BIBREF25. Regarding the gender, Figure FIGREF15 shows that the vast majority of offensive tweets, including vulgar and hate speech, were authored by males. Female Twitter users accounted for 14% of offensive tweets in general and 6% and 9% of vulgar and hate speech respectively. Figure FIGREF16 shows a detailed categorization of hate speech types, where the top three include insulting groups based on their political ideology, origin, and sport affiliation. Religious hate speech appeared in only 15% of all hate speech tweets.\nNext, we analyzed all tweets labeled as offensive to better understand how Arabic speakers use offensive language. Here is a breakdown of usage:\nDirect name calling: The most frequent attack is to call a person an animal name, and the most used animals were كلب> (“klb” – “dog”), حمار> (“HmAr” – “donkey”), and بهيم> (“bhym” – “beast”). The second most common was insulting mental abilities using words such as غبي> (“gby” – “stupid”) and عبيط> (“EbyT” –“idiot”). Some culture-specific differences should be considered. Not all animal names are used as insults. For example, animals such as أسد> (“Asd” – “lion”), صقر> (“Sqr” – “falcon”), and غزال> (“gzAl” – “gazelle”) are typically used for praise. For other insults, people use: some bird names such as دجاجة> (“djAjp” – “chicken”), بومة> (“bwmp” – “owl”), and غراب> (“grAb” – “crow”); insects such as ذبابة> (“*bAbp” – “fly”), صرصور> (“SrSwr” – “cockroach”), and حشرة> (“H$rp” – “insect”); microorganisms such as جرثومة> (“jrvwmp” – “microbe”) and طحالب> (“THAlb” – “algae”); inanimate objects such as جزمة> (“jzmp” – “shoes”) and سطل> (“sTl” – “bucket”) among other usages.\nSimile and metaphor: Users use simile and metaphor were they would compare a person to: an animal as in زي الثور> (“zy Alvwr” – “like a bull”), سمعني نهيقك> (“smEny nhyqk” – “let me hear your braying”), and هز ديلك> (“hz dylk” – “wag your tail”); a person with mental or physical disability such as منغولي> (“mngwly” – “Mongolian (down-syndrome)”), معوق> (“mEwq” – “disabled”), and قزم> (“qzm” – “dwarf”); and to the opposite gender such as جيش نوال> (“jy$ nwAl” – “Nawal's army (Nawal is female name)”) and نادي زيزي> (“nAdy zyzy” – “Zizi's club (Zizi is a female pet name)”).\nIndirect speech: This type of offensive language includes: sarcasm such as أذكى إخواتك> (“A*kY AxwAtk” – “smartest one of your siblings”) and فيلسوف الحمير> (“fylswf AlHmyr” – “the donkeys' philosopher”); questions such as ايه كل الغباء ده> (“Ayh kl AlgbA dh” – “what is all this stupidity”); and indirect speech such as النقاش مع البهايم غير مثمر> (“AlnqA$ mE AlbhAym gyr mvmr” – “no use talking to cattle”).\nWishing Evil: This entails wishing death or major harm to befall someone such as ربنا ياخدك> (“rbnA yAxdk” – “May God take (kill) you”), الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”), and روح في داهية> (“rwH fy dAhyp” – equivalent to “go to hell”).\nName alteration: One common way to insult others is to change a letter or two in their names to produce new offensive words that rhyme with the original names. Some examples of such include changing الجزيرة> (“Aljzyrp” – “Aljazeera (channel)”) to الخنزيرة> (“Alxnzyrp” – “the pig”) and خلفان> (“xlfAn” – “Khalfan (person name)”) to خرفان> (“xrfAn” – “crazed”).\nSocietal stratification: Some insults are associated with: certain jobs such as بواب> (“bwAb” – “doorman”) or خادم> (“xAdm” – “servant”); and specific societal components such بدوي> (“bdwy” – “bedouin”) and فلاح> (“flAH” – “farmer”).\nImmoral behavior: These insults are associated with negative moral traits or behaviors such as حقير> (“Hqyr” – “vile”), خاين> (“xAyn” – “traitor”), and منافق> (“mnAfq” – “hypocrite”).\nSexually related: They include expressions such as خول> (“xwl” – “gay”), وسخة> (“wsxp” – “prostitute”), and عرص> (“ErS” – “pimp”).\nFigure FIGREF17 shows top words with the highest valance score for individual words in the offensive tweets. Larger fonts are used to highlight words with highest score and align as well with the categories mentioned ahead in the breakdown for the offensive languages. We modified the valence score described by BIBREF1 conover2011political to magnify its value based on frequency of occurrence. The score is computed as follows:\n$V(I) = 2 \\frac{ \\frac{tf(I, C_off)}{total(C_off)}}{\\frac{tf(I, C_off)}{total(C_off)} + \\frac{tf(I, C_cln)}{total(C_cln)} } - 1$\nwhere\n$tf(I, C_i) = \\sum _{a \\in I \\bigcap C_i} [ln(Cnt(a, C_i)) + 1]$\n$total(C_i) = \\sum _{I} tf(I, C_i)$\n$Cnt(a, C_i)$ is the number of times word $a$ was used in offensive or clean tweets tweets $C_i$. In essence, we are replacing term frequencies with the natural log of the term frequencies.\nWe looked at MSA and four major dialects, namely Egyptian (EGY), Leventine (LEV), Maghrebi (MGR), and Gulf (GLF).",

        "evidence": "In most other analyses and datasets, the idea of out-of-scope data is not considered, and instead the output classes are intended to cover all possible queries (e.g., TREC BIBREF7). Recent work by BIBREF8 considers a similar problem they call out-of-distribution detection. They use other datasets or classes excluded during training to form the out-of-distribution samples. This means that the out-of-scope samples are from a small set of coherent classes that differ substantially from the in-distribution samples. Similar experiments were conducted for evaluating unknown intent discovery models in BIBREF9. In contrast, our out-of-scope queries cover a broad range of phenomena and are similar in style and often similar in topic to in-scope queries, representing things a user might say given partial knowledge of the capabilities of a system.\nTable TABREF20 compares our dataset with other short-query intent classification datasets. The Snips BIBREF0 dataset and the dataset presented in BIBREF10 are the most similar to the in-scope part of our work, with the same type of conversational agent requests. Like our work, both of these datasets were bootstrapped using crowdsourcing. However, the Snips dataset has only a small number of intents and an enormous number of examples of each. Snips does present a low-data variation, with 70 training queries per intent, in which performance drops slightly. The dataset presented in BIBREF10 has a large number of intent classes, yet also contains a wide range of samples per intent class (ranging from 24 to 5,981 queries per intent, and so is not constrained in all cases).\nBIBREF11 created datasets with constrained training data, but with very few intents, presenting a very different type of challenge. We also include the TREC query classification datasets BIBREF7, which have a large set of labels, but they describe the desired response type (e.g., distance, city, abbreviation) rather than the action intents we consider. Moreover, TREC contains only questions and no commands. Crucially, none of the other datasets summarized in Table TABREF20 offer a feasible way to evaluate out-of-scope performance.\nThe Dialog State Tracking Challenge (DSTC) datasets are another related resource. Specifically, DSTC 1 BIBREF12, DSTC 2 BIBREF13, and DSTC 3 BIBREF14 contain “chatbot style\" queries, but the datasets are focused on state tracking.

        "evidence": "The corpus consists of 53 documents, which contain an average number of 156.1 sentences per document, each with 19.55 tokens on average. The corpus comprises 8,275 sentences and 167,739 words in total. However, as mentioned above, only case presentation sections, headings and abstracts are annotated. The numbers of annotated entities are summarized in Table TABREF24.\nFindings are the most frequently annotated type of entity. This makes sense given that findings paint a clinical picture of the patient's condition. The number of tokens per entity ranges from one token for all types to 5 tokens for cases (average length 3.1), nine tokens for conditions (average length 2.0), 16 tokens for factors (average length 2.5), 25 tokens for findings (average length 2.6) and 18 tokens for modifiers (average length 1.4) (cf. Table TABREF24). Examples of rather long entities are given in Table TABREF25.\nEntities can appear in a discontinuous way. We model this as a relation between two spans which we call “discontinuous” (cf. Figure FIGREF26). Especially findings often appear as discontinuous entities, we found 543 discontinuous finding relations. The numbers for conditions and factors are lower with seven and two, respectively. Entities can also be nested within one another. This happens either when the span of one annotation is completely embedded in the span of another annotation (fully-nested; cf. Figure FIGREF12), or when there is a partial overlapping between the spans of two different entities (partially-nested; cf. Figure FIGREF12). There is a high number of inter-sentential relations in the corpus (cf. Table TABREF27). This can be explained by the fact that the case entity occurs early in each document; furthermore, it is related to finding and factor annotations that are distributed across different sentences.\nThe most frequently annotated relation in our corpus is the has-relation between a case entity and the findings related to that case. This correlates with the high number of finding entities.

These features can be further stratified into two groups: `structured' clinical features and `unstructured' clinical features.\n\nFeature Extraction ::: Structured Features\nStructure features are features that were identified on the EHR using regular expression matching and include rating scores that have been reported in the psychiatric literature as correlated with increased readmission risk, such as Global Assessment of Functioning, Insight and Compliance:\n\nGlobal Assessment of Functioning (GAF): The psychosocial functioning of the patient ranging from 100 (extremely high functioning) to 1 (severely impaired) BIBREF13.\n\nInsight: The degree to which the patient recognizes and accepts his/her illness (either Good, Fair or Poor).\n\nCompliance: The ability of the patient to comply with medication and to follow medical advice (either Yes, Partial, or None).\n\nThese features are widely-used in clinical practice and evaluate the general state and prognosis of the patient during the patient's evaluation.\n\nFeature Extraction ::: Unstructured Features\nUnstructured features aim to capture the state of the patient in relation to seven risk factor domains (Appearance, Thought Process, Thought Content, Interpersonal, Substance Use, Occupation, and Mood) from the free-text narratives on the EHR. These seven domains have been identified as associated with readmission risk in prior work BIBREF14.\n\nThese unstructured features include: 1) the relative number of sentences in the admission notes that involve each risk factor domain (out of total number of sentences within the admission) and 2) clinical sentiment scores for each of these risk factor domains, i.e. sentiment scores that evaluate the patient’s psychosocial functioning level (positive, negative, or neutral) with respect to each of these risk factor domain.",

        "question": "Why do audiophiles spend lots of money on high-end audio equipment and does more expensive gear always sound better than less expensive hardware?",
        "evidence": "",
        "answer": "While it is generally true that audiophiles are willing to spend more money on high-end gear than those less passionate about audio, justification for this additional financial outlay is not solely based on the equipment’s definitive sonic superiority.\n \nThere are a handful of key attributes that define audio equipment’s performance, including: frequency response, detail, texture, layering ability, coherency, vocal presentation, and timbre and tonality. Audiophiles typically seek out gear capable of performing well in many or all of these areas, and it is often these elevated expectations that drive an audiophile’s willingness to spend more. However, there are elements of subjectivity at play, as well as physiological differences, that can lead to variations in interpretation of what sounds “accurate” or “engaging.” Therefore, even if it is generally true that most expensive audio equipment objectively performs better than their lesser priced counterparts, individual preference and anatomy can cause differences in expectations or hearing that can lead to different perceptions of sonic performance, even with high-end audio gear.\n \nThe Erlkonig is an In-Ear Monitor made by German producer, Vision Ears. By many, it is thought to be one of the best In-Ear Monitors ever made. At a retail price of over $4,000, it is also generally considered to be quite expensive. Widely regarded to perform extremely well, the Erlkonig has 13 balance armature drivers, 4 user-selectable sound settings, and shells made out of silver. While non-audiophiles will likely scoff at its price and be indifferent to the Erlkonig’s specifications, many audiophiles will salivate at the chance for even a single listen. Even though many deep-pocketed audiophiles could justifiably purchase the Erlkonig, there are plenty of audiophiles and non-audiophiles who do not enjoy the IEM’s sound. For others, the shell is ergonomically incompatible with their ears. So, even if expensive audio gear on the whole performs and sounds “better” than lesser priced gear, unique preferences and anatomical variation also shape perception of sonic performance.",

Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nWe define a novel problem of predicting negotiation outcomes from a fraction of the dialogue (Section 2).",

This is in contrast to prior work which has successfully linked language models to the N400 BIBREF0 and P600 BIBREF7 but not the other ERP components. We also note that contrary to BIBREF7 , we find that an LSTM does contain information that can be used to predict EEG data, and in particular that it can predict the P600. We speculate that the analysis used in BIBREF7 did not find reliable effects because the language models were related to the EEG data through functions chosen a priori (the surprisal, and the `distance' metric). These functions, though interpretable, might be interpretable at the cost of losing much of the information in the representations learned by the network.\nIn addition, we show through our multitask learning analysis that information is shared between ERP components, and between ERP components and behavioral data. Although these relationships must be viewed with caution until they can be verified across multiple datasets and with more variation in neural network architectures, here we consider some potential reasons for our findings.

        "evidence": "Word Sense Disambiguation (WSD) is a fundamental task and long-standing challenge in Natural Language Processing (NLP), which aims to find the exact sense of an ambiguous word in a particular context BIBREF0. Previous WSD approaches can be grouped into two main categories: knowledge-based and supervised methods.\nKnowledge-based WSD methods rely on lexical resources like WordNet BIBREF1 and usually exploit two kinds of lexical knowledge. The gloss, which defines a word sense meaning, is first utilized in Lesk algorithm BIBREF2 and then widely taken into account in many other approaches BIBREF3, BIBREF4. Besides, structural properties of semantic graphs are mainly used in graph-based algorithms BIBREF5, BIBREF6.\nTraditional supervised WSD methods BIBREF7, BIBREF8, BIBREF9 focus on extracting manually designed features and then train a dedicated classifier (word expert) for every target lemma.\nAlthough word expert supervised WSD methods perform better, they are less flexible than knowledge-based methods in the all-words WSD task BIBREF10. Recent neural-based methods are devoted to dealing with this problem. BIBREF11 present a supervised classifier based on Bi-LSTM, which shares parameters among all word types except the last layer. BIBREF10 convert WSD task to a sequence labeling task, thus building a unified model for all polysemous words. However, neither of them can totally beat the best word expert supervised methods.\nMore recently, BIBREF12 propose to leverage the gloss information from WordNet and model the semantic relationship between the context and gloss in an improved memory network. Similarly, BIBREF13 introduce a (hierarchical) co-attention mechanism to generate co-dependent representations for the context and gloss. Their attempts prove that incorporating gloss knowledge into supervised WSD approach is helpful, but they still have not achieved much improvement, because they may not make full use of gloss knowledge.\nIn this paper, we focus on how to better leverage gloss information in a supervised neural WSD system. Recently, the pre-trained language models, such as ELMo BIBREF14 and BERT BIBREF15, have shown their effectiveness to alleviate the effort of feature engineering. Especially, BERT has achieved excellent results in question answering (QA) and natural language inference (NLI). We construct context-gloss pairs from glosses of all possible senses (in WordNet) of the target word, thus treating WSD task as a sentence-pair classification problem. We fine-tune the pre-trained BERT model and achieve new state-of-the-art results on WSD task. In particular, our contribution is two-fold:\n1. We construct context-gloss pairs and propose three BERT-based models for WSD.\n2. We fine-tune the pre-trained BERT model, and the experimental results on several English all-words WSD benchmark datasets show that our approach significantly outperforms the state-of-the-art systems.\nWord Sense Disambiguation (WSD) is a fundamental task and long-standing challenge in Natural Language Processing (NLP), which aims to find the exact sense of an ambiguous word in a particular context (Navigli, 2009).",

        "answer": "A new model compression approach, Patient Knowledge Distillation (Patient-KD).",
        "evidence": "Language model pre-training has proven to be highly effective in learning universal language representations from large-scale unlabeled data. ELMo BIBREF0, GPT BIBREF1 and BERT BIBREF2 have achieved great success in many NLP tasks, such as sentiment classification BIBREF3, natural language inference BIBREF4, and question answering BIBREF5.\nDespite its empirical success, BERT's computational efficiency is a widely recognized issue because of its large number of parameters. For example, the original BERT-Base model has 12 layers and 110 million parameters. Training from scratch typically takes four days on 4 to 16 Cloud TPUs. Even fine-tuning the pre-trained model with task-specific dataset may take several hours to finish one epoch. Thus, reducing computational costs for such models is crucial for their application in practice, where computational resources are limited.\nMotivated by this, we investigate the redundancy issue of learned parameters in large-scale pre-trained models, and propose a new model compression approach, Patient Knowledge Distillation (Patient-KD), to compress original teacher (e.g., BERT) into a lightweight student model without performance sacrifice. In our approach, the teacher model outputs probability logits and predicts labels for the training samples (extendable to additional unannotated samples), and the student model learns from the teacher network to mimic the teacher's prediction.\nDifferent from previous knowledge distillation methods BIBREF6, BIBREF7, BIBREF8, we adopt a patient learning mechanism: instead of learning parameters from only the last layer of the teacher, we encourage the student model to extract knowledge also from previous layers of the teacher network. We call this `Patient Knowledge Distillation'. This patient learner has the advantage of distilling rich information through the deep structure of the teacher network for multi-layer knowledge distillation.\nWe also propose two different strategies for the distillation process: ($i$) PKD-Last: the student learns from the last $k$ layers of the teacher, under the assumption that the top layers of the original network contain the most informative knowledge to teach the student; and ($ii$) PKD-Skip: the student learns from every $k$ layers of the teacher, suggesting that the lower layers of the teacher network also contain important information and should be passed along for incremental distillation.\nWe evaluate the proposed approach on several NLP tasks, including Sentiment Classification, Paraphrase Similarity Matching, Natural Language Inference, and Machine Reading Comprehension. Experiments on seven datasets across these four tasks demonstrate that the proposed Patient-KD approach achieves superior performance and better generalization than standard knowledge distillation methods BIBREF6, with significant gain in training efficiency and storage reduction while maintaining comparable model accuracy to original large models. To the authors' best knowledge, this is the first known effort for BERT model compression.\nMotivated by this, we investigate the redundancy issue of learned parameters in large-scale pre-trained models, and propose a new model compression approach, Patient Knowledge Distillation (Patient-KD), to compress original teacher (e.g., BERT) into a lightweight student model without performance sacrifice.",

        "evidence": "The previous work that is most relevant to our work here is that of BIBREF9, who developed the ClaimBuster system, which assigns each sentence in a document a score, i.e., a number between 0 and 1 showing how worthy it is of fact-checking. The system is trained on their own dataset of about eight thousand debate sentences (1,673 of them check-worthy), annotated by students, university professors, and journalists. Unfortunately, this dataset is not publicly available and it contains sentences without context as about 60% of the original sentences had to be thrown away due to lack of agreement.\nIn contrast, we develop a new publicly-available dataset, based on manual annotations of political debates by nine highly-reputed fact-checking sources, where sentences are annotated in the context of the entire debate. This allows us to explore a novel approach, which focuses on the context.\nNote also that the ClaimBuster dataset is annotated following guidelines from BIBREF9 rather than a real fact-checking website; yet, it was evaluated against CNN and PolitiFact BIBREF10. In contrast, we train and evaluate directly on annotations from fact-checking websites, and thus we learn to fit them better.\nBeyond the document context, it has been proposed to mine check-worthy claims on the Web. For example, BIBREF11 searched for linguistic cues of disagreement between the author of a statement and what is believed, e.g., “falsely claimed that X”. The claims matching the patterns go through a statistical classifier, which marks the text of the claim. This procedure can be used to acquire a dataset of disputed claims from the Web.\nGiven a set of disputed claims, BIBREF12 approached the task as locating new claims on the Web that entail the ones that have already been collected. Thus, the task can be conformed as recognizing textual entailment, which is analyzed in detail in BIBREF13.\nFinally, BIBREF14 argued that the top terms in claim vs. non-claim sentences are highly overlapping, which is a problem for bag-of-words approaches. Thus, they used a Convolutional Neural Network, where each word is represented by its embedding and each named entity is replaced by its tag, e.g., person, organization, location.\nThe system is trained on their own dataset of about eight thousand debate sentences (1,673 of them check-worthy), annotated by students, university professors, and journalists.",

        "evidence": "Both neural and statistical machine translation approaches are highly reliant on the availability of large amounts of data and are known to perform poorly in low resource settings. Recent crowd-sourcing efforts and workshops on machine translation have resulted in small amounts of parallel texts for building viable machine translation systems for low-resource pairs BIBREF0 . But, they have been shown to suffer from low accuracy (incorrect translation) and low coverage (high out-of-vocabulary rates), due to insufficient training data. In this project, we try to address the high OOV rates in low-resource machine translation systems by leveraging the increasing amount of multilingual content available on the Internet for enriching the bilingual lexicon.\nComparable corpora such as Wikipedia, are collections of topic-aligned but non-sentence-aligned multilingual documents which are rich resources for extracting parallel sentences from. For example, Figure FIGREF1 shows that there are equivalent sentences on the page about Donald Trump in Tamil and English, and the phrase alignment for an example sentence is shown in Table TABREF4 .\nTable TABREF2 shows that there are at least tens of thousands of bilingual articles on Wikipedia which could potentially have at least as many parallel sentences that could be mined to address the scarcity of parallel sentences as indicated in column 2 which shows the number of sentence-pairs in the largest available bilingual corpora for xx-en. As shown by BIBREF1 ( BIBREF1 ), the illustrated data sparsity can be addressed by extending the scarce parallel sentence-pairs with those automatically extracted from Wikipedia and thereby improving the performance of statistical machine translation systems.\nIn this paper, we will propose a neural approach to parallel sentence extraction and compare the BLEU scores of machine translation systems with and without the use of the extracted sentence pairs to justify the effectiveness of this method. Compared to previous approaches which require specialized meta-data from document structure or significant amount of hand-engineered features, the neural model for extracting parallel sentences is learned end-to-end using only a small bootstrap set of parallel sentence pairs.\nIn this paper, we will propose a neural approach to parallel sentence extraction and compare the BLEU scores of machine translation systems with and without the use of the extracted sentence pairs to justify the effectiveness of this method.",

        "evidence": "Zero anaphora is a discourse phenomenon, where pronouns can be omitted when they are pragmatically or grammatically inferable from intra- and inter-sentential context BIBREF0 . However, translating such implicit information (i.e. zero pronoun, ZP) poses various difficulties for machine translation (MT) in terms of completeness and correctness. Although neural models are getting better at learning representations, it is still difficult to implicitly learn complex ZPs in a general model. Actually, ZP prediction and translation need to not only understand the semantics or intentions of a single sentence, but also utilize its discourse-level context.\nTwo technological advances in the field of ZP and MT, have seen vast progress over the last decades, but they have been developed very much in isolation. Early studies BIBREF1 , BIBREF2 , BIBREF3 fed MT systems with the results of ZP prediction models, which are trained on a small-scale and non-homologous data compared to MT models. To narrow the data-level gap, Wang:2016:NAACL proposed an automatic method to annotate ZPs by utilizing the parallel corpus of MT. The homologous data for both ZP prediction and translation leads to significant improvements on translation performances for both statistical MT BIBREF4 and neural MT models BIBREF5 . However, such approaches still require external ZP prediction models, which have a low accuracy of 66%. The numerous errors of ZP prediction errors will be propagated to translation models, which leads to new translation problems. In addition, relying on external ZP prediction models in decoding makes these approaches unwieldy in practice, due to introducing more computation cost and pipeline complexity.\nIn this work, we try to further bridge the model-level gap by jointly modeling ZP prediction and translation. Joint learning has proven highly effective on alleviating the error propagation problem, such as joint parsing and translation BIBREF6 , as well as joint tokenization and translation BIBREF7 . Similarly, we expect that ZP prediction and translation could interact with each other: prediction offers more ZP information beyond 1-best result to translation and translation helps prediction resolve ambiguity. Specifically, we first cast ZP prediction as a sequence labeling task with a neural model, which is trained jointly with a standard neural machine translation (NMT) model in an end-to-end manner. We leverage the auto-annotated ZPs to supervise the learning of ZP prediction component, which releases the reliance on external ZP knowledge in decoding phase.\nIn addition, previous studies revealed that discourse-level information can better tackle ZP resolution, because around 23% of ZPs appear two or more sentences away from their antecedents BIBREF8 , BIBREF9 . Inspired by these findings, we exploit inter-sentential context to further improve ZP prediction and thus translation. Concretely, we employ hierarchical neural networks BIBREF10 , BIBREF11 to summarize the context of previous sentences in a text, which is integrated to the joint model for ZP prediction.\nWe validate the proposed approach on the widely-used data for ZP translation BIBREF5 , which consist of 2.15M Chinese–English sentence pairs. Experimental results show that the joint model indeed improves performances on both ZP prediction and translation. Incorporating discourse-level context further improves performances, and outperforms ther external ZP prediction model BIBREF5 by +2.29 BLEU points in translation and +11% in prediction accuracy. Experimental results on a further Japanese–English translation task show that our model consistently outperforms both the baseline and the external ZP prediction model, demonstrating the universality of the proposed approach.\nThe key contributions of this paper are:\nSpecifically, we first cast ZP prediction as a sequence labeling task with a neural model, which is trained jointly with a standard neural machine translation (NMT) model in an end-to-end manner.",

        "answer": "Margaret Thatcher was the first woman to be elected prime minister of Great Britain and Northern Ireland, serving in this role from her first election victory in 1979 until she was forced out of office by members of her own party in 1990. During this time she transformed the economic situation in the United Kingdom by introducing economic policies intended to reverse high inflation and weak growth. By constraining the power of trades unions and overseeing extensive deregulation and privatisation, Thatcher helped to create a period of extended growth and economic success. Together with Ronald Reagan, she was also instrumental in recognising and supporting the opportunity to end communist rule in the Soviet Union, where she was dubbed the 'Iron Lady', through her friendship with the Russian leader, Mikhail Gorbachev. Her legacy was to end the so-called 'post-war consensus' in the UK (characterised by high taxes, regulation and nationalisation) and to replace it with policies that encouraged free-enterprise and personal responsibility while acknowledging the importance of the welfare state, provided it was administered responsibly.

We hope the content-level diversity can be fully captured by the content selector for a more interpretable and controllable generation process. Following BIBREF6 , BIBREF16 , we define content selection as a sequence labeling task. Let INLINEFORM0 denote a sequence of binary selection masks. INLINEFORM1 if INLINEFORM2 is selected and 0 otherwise. INLINEFORM3 is assumed to be independent from each other and is sampled from a bernoulli distribution INLINEFORM4 . INLINEFORM6 is the bernoulli parameter, which we estimate using a two-layer feedforward network on top of the source encoder. Text are generated by first sampling INLINEFORM7 from INLINEFORM8 to decide which content to cover, then decode with the conditional distribution INLINEFORM9 . The text is expected to faithfully convey all selected contents and drop unselected ones. Fig. FIGREF8 depicts this generation process. Note that the selection is based on the token-level context-aware embeddings INLINEFORM10 and will maintain information from the surrounding contexts. It encourages the decoder to stay faithful to the original information instead of simply fabricating random sentences by connecting the selected tokens.\nThe most intuitive way is training the content selector to target some heuristically extracted contents. For example, we can train the selector to select overlapped words between the source and target BIBREF6 , sentences with higher tf-idf scores BIBREF20 or identified image objects that appear in the caption BIBREF21 . A standard encoder-decoder model is independently trained. In the testing stage, the prediction of the content selector is used to hard-mask the attention vector to guide the text generation in a bottom-up way. Though easy to train, Bottom-up generation has the following two problems: (1) The heuristically extracted contents might be coarse and cannot reflect the variety of human languages and (2) The selector and decoder are independently trained towards different objectives thus might not adapt to each other well.\nINLINEFORM0 as Latent Variable: Another way is to treat INLINEFORM1 as a latent variable and co-train selector and generator by maximizing the marginal data likelihood.

        "question": "Where did Adlai Stevenson II spend his early life?",
        "evidence": "Adlai Ewing Stevenson II was born in Los Angeles, California, in a neighborhood that is now designated as the North University Park Historic District. His home and birthplace at 2639 Monmouth Avenue has been designated as a Los Angeles Historic-Cultural Monument. He was a member of a prominent Illinois political family. His grandfather and namesake Adlai Stevenson I was Vice President of the United States under President Grover Cleveland from 1893 to 1897. His father, Lewis Stevenson, never held an elected office, but was appointed Illinois Secretary of State (1914–1917) and was considered a strong contender for the Democratic vice-presidential nomination in 1928. A maternal great-grandfather, Jesse W. Fell, had been a close friend and campaign manager for Abraham Lincoln in his 1858 US Senate race; Stevenson often referred to Fell as his favorite ancestor. Stevenson's eldest son, Adlai E. Stevenson III, became a U.S. Senator from Illinois (1970–1981). His mother was Helen Davis Stevenson, and he had an older sister, Elizabeth Stevenson Ives, an author who was called \"Buffie\". Actor McLean Stevenson was a second cousin once removed. He was the nephew by marriage of novelist Mary Borden, and she assisted in the writing of some of his political speeches.\n\nStevenson was raised in the city of Bloomington, Illinois; his family was a member of Bloomington's upper class and lived in one of the city's well-to-do neighborhoods. On December 30, 1912, at the age of twelve, Stevenson accidentally killed Ruth Merwin, a 16-year-old friend, while demonstrating drill technique with a rifle, inadvertently left loaded, during a party at the Stevenson home. Stevenson was devastated by the accident and rarely mentioned or discussed it as an adult, even with his wife and children. However, in 1955 Stevenson heard about a woman whose son had experienced a similar tragedy. He wrote to her that she should tell her son that \"he must now live for two\", which Stevenson's friends took to be a reference to the shooting incident.\n\nStevenson left Bloomington High School after his junior year and attended University High School in Normal, Illinois, Bloomington's \"twin city\", just to the north. He then went to boarding school in Connecticut at The Choate School (now Choate Rosemary Hall), where he played on the tennis team, acted in plays, and was elected editor-in-chief of The Choate News, the school newspaper. Upon his graduation from Choate in 1918, he enlisted in the United States Naval Reserve and served at the rank of seaman apprentice, but his training was completed too late for him to participate in World War I.\n\nHe attended Princeton University, becoming managing editor of The Daily Princetonian, a member of the American Whig-Cliosophic Society, a member of the Quadrangle Club, and received a B.A. degree in 1922 in literature and history. Under prodding from his father he then went to Harvard Law School, but found the law to be \"uninteresting\", and withdrew after failing several classes. He returned to Bloomington where he wrote for the family newspaper, The Daily Pantagraph, which was founded by his maternal great-grandfather Jesse Fell. The Pantagraph, which had one of the largest circulations of any newspaper in Illinois outside the Chicago area, was a main source of the Stevenson family's wealth. Following his mother's death in 1935, Adlai inherited one-quarter of the Pantagraph's stock, providing him with a large, dependable source of income for the rest of his life.\n\nA year after leaving Harvard, Stevenson became interested in the law again after talking to Supreme Court Justice Oliver Wendell Holmes Jr. When he returned home to Bloomington, he decided to finish his degree at Northwestern University School of Law, attending classes during the week and returning to Bloomington on the weekends to write for the Pantagraph. Stevenson received his J.D. degree from Northwestern in 1926 and passed the Illinois state bar examination that year. He obtained a position at Cutting, Moore & Sidley, one of Chicago's oldest and most prestigious law firms.",

        "evidence": "Significant progress has been made in the field of machine learning in the past years due to the rapid development of deep learning BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5. Dating back to the dramatic increase in the accuracy of large-scale automatic speech recognition (ASR) using fully connected deep neural networks (DNN) and deep auto-encoders around 2010 BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, and followed by a set of breakthroughs in computer vision (CV) using deep convolutional neural network (CNN) models BIBREF17 for large-scale image classification around 2012 BIBREF18, BIBREF19, BIBREF20, BIBREF21 and large-scale object detection BIBREF22, BIBREF23, BIBREF24 around 2014, a set of major milestones have been achieved in pattern recognition with single input modality. Subsequently, in natural language processing (NLP), recurrent neural network (RNN) based semantic slot filling methods BIBREF25 achieved new state-of-the-art in spoken language understanding, and RNN-encoder-decoder models with attention mechanism BIBREF26, also referred to as sequence to sequence models BIBREF27, produced superior performance in machine translation in an end-to-end fashion BIBREF28, BIBREF29. For other NLP tasks without much training data, such as question answering (QA) and machine reading comprehension, generative pre-training that transfers parameters from a language model (LM) pre-trained on a large out-of-domain data set using unsupervised or self learning then followed by fine-tuning on small in-domain data sets, achieved record-breaking results over a set of tasks BIBREF30, BIBREF31, BIBREF32.\nDespite the advances in vision, speech, and language processing, many problems in artificial intelligence involve more than one modality, such as an intelligent personal assistant (IPA) that should understand human communicative intentions embedded not only in spoken language, but also in body and pictorial languages BIBREF33. Therefore, it is of broad interests to study the modeling and learning approaches across multiple modalities BIBREF34. Benefiting from the advances in image processing and language understanding BIBREF35, a set of tasks that combine both image and text have drawn much attention, which include visual grounding tasks like referring expression understanding and phrase localization BIBREF36, BIBREF37, BIBREF38, image captioning BIBREF39, BIBREF40, BIBREF41, visual QA (VQA) BIBREF42, BIBREF43, BIBREF44, text-to-image generation BIBREF45, BIBREF46, BIBREF47, and visual-language navigation BIBREF48 etc. In these tasks, natural language plays a key role in helping the machine to “understand” the content of the images, where “understand” means to capture the underlying correlations between the semantics embedded in language with the visual features obtained from the images. In addition to text, vision can be combined with speech as well. Such tasks include audio-visual speech recognition BIBREF49, BIBREF50, BIBREF51, speaker recognition BIBREF52, BIBREF53, BIBREF54, as well as speech diarisation BIBREF55, BIBREF56, separation BIBREF57, BIBREF58 and enhancement BIBREF59, which mostly focused on the use of visual features to improve the robustness of the audio-only methods.\nIn this paper, a technical review of the models and learning methods for multimodal intelligence is provided. The main focus is the combination of CV and NLP, which has become an important area for both research communities covering many different tasks and technologies. To provide a more structured perspective, we organize the methods selected in this technical review according to three key topics: representation, fusion, and applications.\nLearning representations for the input data is a core problem for deep learning. For multimodal tasks, collecting paralleled data across all modalities can be quite difficult and leveraging pre-trained representations with desired properties, such as suitable for zero-shot or few-shot learning, is often an effective solution to the issue. Both supervised and unsupervised training based multimodal representation learning methods are reviewed.\nThe fusion of the features or representations of the single modalities is undoubtedly a centric problem of any multimodal task. Different from previous studies that often categorise the related work into early, middle and late stage methods based on the stage that fusion happens in the procedure, we classify them according to the actual operation used in the fusion, such as attention and bilinear pooling, since it becomes difficult to classify some recent complex approaches into stages.\nThree types of applications are reviewed in this paper, namely image captioning, text-to-image synthesis and VQA. This is to give an idea how representation learning and fusion can be applied to specific tasks, and to provide a viewpoint of the situation of the current development of the multimodal applications, especially those integrating vision with natural languages. Visual reasoning methods for VQA are also discussed in the end.\nThis paper is organised as follows. Section SECREF2 reviews the recent progress on developing representations for single or multiple modalities. Section SECREF3 introduces the commonly used fusion methods, particularly attention and bilinear pooling. Applications including caption generation, text-to-image synthesis, VQA, and visual reasoning are introduced in Section SECREF4, followed by conclusions.\nTo provide a more structured perspective, we organize the methods selected in this technical review according to three key topics: representation, fusion, and applications.",

        "question": "Is the proposed model static or dynamic?",
        "answer": "Dynamic.",
        "evidence": "The goal of Machine Reading Comprehension (MRC) is to have machines read a text passage and then generate an answer (or select an answer from a list of given candidates) for any question about the passage. There has been a growing interest in the research community in exploring neural MRC models in an end-to-end fashion, thanks to the availability of large-scale datasets, such as CNN/DM BIBREF0 and SQuAD BIBREF1 .\nDespite the variation in model structures, most state-of-the-art models perform reading comprehension in two stages. First, the symbolic representations of passages and questions are mapped into vectors in a neural space. This is commonly achieved via embedding and attention BIBREF2 , BIBREF3 or fusion BIBREF4 . Then, reasoning is performed on the vectors to generate the right answer.\nIdeally, the best attention and reasoning strategies should adapt organically in order to answer different questions. However, most MRC models use a static attention and reasoning strategy indiscriminately, regardless of various question types. One hypothesis is because these models are optimized on those datasets whose passages and questions are domain-specific (or of a single type). For example, in CNN/DM, all the passages are news articles, and the answer to each question is an entity in the passage. In SQuAD, the passages came from Wikipedia articles and the answer to each question is a text span in the article. Such a fixed-strategy MRC model does not adapt well to other datasets. For example, the exact-match score of BiDAF BIBREF2 , one of the best models on SQuAD, drops from 81.5 to 55.8 when applied to TriviaQA BIBREF5 , whereas human performance is 82.3 and 79.7 on SQuAD and TriviaQA, respectively.\nIn real-world MRC tasks, we must deal with questions and passages of different types and complexities, which calls for models that can dynamically determine what attention and reasoning strategy to use for any input question-passage pair on the fly. In a recent paper, BIBREF6 proposed dynamic multi-step reasoning, where the number of reasoning steps is determined spontaneously (using reinforcement learning) based on the complexity of the input question and passage. With a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.\nThe proposed model is called a Dynamic Fusion Network (DFN). In this paper, we describe the version of DFN developed on the RACE dataset BIBREF7 . In RACE, a list of candidate answers is provided for each passage-question pair. So DFN for RACE is a scoring model - the answer candidate with the highest score will be selected as the final answer.\nLike other MRC models, DFNs also perform machine reading in two stages: attention and reasoning. DFN is unique in its use of a dynamic multi-strategy attention process in the attention stage. Here “attention” refers to the process that texts from different sources (passage, question, answers) are combined in the network. In literature, a fixed attention mechanism is usually employed in MRC models. In DFN, the attention strategy is not static; instead, the actual strategy for drawing attention among the three text sources are chosen on the fly for each sample. This lends flexibility to adapt to various question types that require different comprehension skills. The output of the attention stage is then fed into the reasoning module to generate the answer score. The reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.\nInspired by ReasoNet BIBREF6 and dynamic neural module networks BIBREF8 , we use deep reinforcement learning methods BIBREF9 , BIBREF10 to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample. We use RL in favor of other simpler methods (like cascading, pooling or weighted averaging) mainly because we intend to learn a policy that constructs an instance of DFN of a sample-specific structure. Given an input sample consisting of a question, a passage and a list of candidate answers in RACE, an instance of DFN can be constructed via RL step by step on the fly. Such a policy is particularly appealing as it also provides insights on how the model performs on different types of questions. At each decision step, the policy maps its “state”, which represents an input sample, and DFN's partial knowledge of the right answer, to the action of assembling proper attention and reasoning modules for DFN.\nExperiments conducted on the RACE dataset show that DFN significantly outperforms previous state-of-the-art MRC models and has achieved the best result reported on RACE. A thorough empirical analysis also demonstrates that DFN is highly effective in understanding passages of a wide variety of styles and answering questions of different complexities.\nWith a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention.",

        "answer": "Automatic quality assessment in cQA is the task of determining whether an answer is of high quality, selected as the best answer, or ranked higher than other answers.",
        "evidence": "A variety of approaches have been proposed for document quality assessment across different domains: Wikipedia article quality assessment, academic paper rating, content quality assessment in community question answering (cQA), and essay scoring. Among these approaches, some use hand-crafted features while others use neural networks to learn features from documents. For each domain, we first briefly describe feature-based approaches and then review neural network-based approaches. Wikipedia article quality assessment: Quality assessment of Wikipedia articles is a task that assigns a quality class label to a given Wikipedia article, mirroring the quality assessment process that the Wikipedia community carries out manually. Many approaches have been proposed that use features from the article itself, meta-data features (e.g., the editors, and Wikipedia article revision history), or a combination of the two. Article-internal features capture information such as whether an article is properly organized, with supporting evidence, and with appropriate terminology. For example, BIBREF3 use writing styles represented by binarized character trigram features to identify featured articles. BIBREF4 and BIBREF0 explore the number of headings, images, and references in the article. BIBREF5 use nine readability scores, such as the percentage of difficult words in the document, to measure the quality of the article. Meta-data features, which are indirect indicators of article quality, are usually extracted from revision history, and the interaction between editors and articles. For example, one heuristic that has been proposed is that higher-quality articles have more edits BIBREF6 , BIBREF7 . BIBREF8 use the percentage of registered editors and the total number of editors of an article. Article–editor dependencies have also been explored. For example, BIBREF9 use the authority of editors to measure the quality of Wikipedia articles, where the authority of editors is determined by the articles they edit. Deep learning approaches to predicting Wikipedia article quality have also been proposed. For example, BIBREF10 use a version of doc2vec BIBREF11 to represent articles, and feed the document embeddings into a four hidden layer neural network. BIBREF12 first obtain sentence representations by averaging words within a sentence, and then apply a biLSTM BIBREF13 to learn a document-level representation, which is combined with hand-crafted features as side information. BIBREF14 exploit two stacked biLSTMs to learn document representations.\nAcademic paper rating: Academic paper rating is a relatively new task in NLP/AI, with the basic formulation being to automatically predict whether to accept or reject a paper. BIBREF2 explore hand-crafted features, such as the length of the title, whether specific words (such as outperform, state-of-the-art, and novel) appear in the abstract, and an embedded representation of the abstract as input to different downstream learners, such as logistic regression, decision tree, and random forest. BIBREF15 exploit a modularized hierarchical convolutional neural network (CNN), where each paper section is treated as a module. For each paper section, they train an attention-based CNN, and an attentive pooling layer is applied to the concatenated representation of each section, which is then fed into a softmax layer.\nContent quality assessment in cQA: Automatic quality assessment in cQA is the task of determining whether an answer is of high quality, selected as the best answer, or ranked higher than other answers. To measure answer content quality in cQA, researchers have exploited various features from different sources, such as the answer content itself, the answerer's profile, interactions among users, and usage of the content. The most common feature used is the answer length BIBREF16 , BIBREF17 , with other features including: syntactic and semantic features, such as readability scores. BIBREF18 ; similarity between the question and the answer at lexical, syntactic, and semantic levels BIBREF18 , BIBREF19 , BIBREF20 ; or user data (e.g., a user's status points or the number of answers written by the user). There have also been approaches using neural networks. For example, BIBREF21 combine CNN-learned representations with hand-crafted features to predict answer quality. BIBREF22 use a 2-dimensional CNN to learn the semantic relevance of an answer to the question, and apply an LSTM to the answer sequence to model thread context. BIBREF23 and BIBREF24 model the problem similarly to machine translation quality estimation, treating answers as competing translation hypotheses and the question as the reference translation, and apply neural machine translation to the problem. Essay scoring: Automated essay scoring is the task of assigning a score to an essay, usually in the context of assessing the language ability of a language learner. The quality of an essay is affected by the following four primary dimensions: topic relevance, organization and coherence, word usage and sentence complexity, and grammar and mechanics. To measure whether an essay is relevant to its “prompt” (the description of the essay topic), lexical and semantic overlap is commonly used BIBREF25 , BIBREF26 . BIBREF27 explore word features, such as the number of verb formation errors, average word frequency, and average word length, to measure word usage and lexical complexity. BIBREF28 use sentence structure features to measure sentence variety. The effects of grammatical and mechanic errors on the quality of an essay are measured via word and part-of-speech $n$ -gram features and “mechanics” features BIBREF29 (e.g., spelling, capitalization, and punctuation), respectively. BIBREF30 , BIBREF31 , and BIBREF32 use an LSTM to obtain an essay representation, which is used as the basis for classification. Similarly, BIBREF33 utilize a CNN to obtain sentence representation and an LSTM to obtain essay representation, with an attention layer at both the sentence and essay levels.\nContent quality assessment in cQA: Automatic quality assessment in cQA is the task of determining whether an answer is of high quality, selected as the best answer, or ranked higher than other answers.",

        "question": "How do they further modify their model to achieve semantic consistency and length consistency?",
        "answer": "The CTC classification layer and the word embedding matrix are mapped to the same latent space and bridge the length gap between the length of the speech encoder output and the length of the natural sentence.",
        "evidence": "Speech-to-Text translation (ST) is essential for a wide range of scenarios: for example in emergency calls, where agents have to respond emergent requests in a foreign language BIBREF0; or in online courses, where audiences and speakers use different languages BIBREF1. To tackle this problem, existing approaches can be categorized into cascaded method BIBREF2, BIBREF3, where a machine translation (MT) model translates outputs of an automatic speech recognition (ASR) system into target language, and end-to-end method BIBREF4, BIBREF5, where a single model learns acoustic frames to target word sequence mappings in one step towards the final objective of interest. Although the cascaded model remains the dominant approach due to its better performance, the end-to-end method becomes more and more popular because it has lower latency by avoiding inferences with two models and rectifies the error propagation in theory.\nSince it is hard to obtain a large-scale ST dataset, multi-task learning BIBREF5, BIBREF6 and pre-training techniques BIBREF7 have been applied to end-to-end ST model to leverage large-scale datasets of ASR and MT. A common practice is to pre-train two encoder-decoder models for ASR and MT respectively, and then initialize the ST model with the encoder of the ASR model and the decoder of the MT model. Subsequently, the ST model is optimized with the multi-task learning by weighing the losses of ASR, MT, and ST. This approach, however, causes a huge gap between pre-training and fine-tuning, which are summarized into three folds:\nSubnet Waste: The ST system just reuses the ASR encoder and the MT decoder, while discards other pre-trained subnets, such as the MT encoder. Consequently, valuable semantic information captured by the MT encoder cannot be inherited by the final ST system.\nRole Mismatch: The speech encoder plays different roles in pre-training and fine-tuning. The encoder is a pure acoustic model in pre-training, while it has to extract semantic and linguistic features additionally in fine-tuning, which significantly increases the learning difficulty.\nNon-pre-trained Attention Module: Previous work BIBREF6 trains attention modules for ASR, MT and ST respectively, hence, the attention module of ST does not benefit from the pre-training.\nTo address these issues, we propose a Tandem Connectionist Encoding Network (TCEN), which is able to reuse all subnets in pre-training, keep the roles of subnets consistent, and pre-train the attention module. Concretely, the TCEN consists of three components, a speech encoder, a text encoder, and a target text decoder. Different from the previous work that pre-trains an encoder-decoder based ASR model, we only pre-train an ASR encoder by optimizing the Connectionist Temporal Classification (CTC) BIBREF8 objective function. In this way, the additional decoder of ASR is not required while keeping the ability to read acoustic features into the source language space by the speech encoder. Besides, the text encoder and decoder can be pre-trained on a large MT dataset. After that, we employ common used multi-task learning method to jointly learn ASR, MT and ST tasks.\nCompared to prior works, the encoder of TCEN is a concatenation of an ASR encoder and an MT encoder and our model does not have an ASR decoder, so the subnet waste issue is solved. Furthermore, the two encoders work at tandem, disentangling acoustic feature extraction and linguistic feature extraction, ensuring the role consistency between pre-training and fine-tuning. Moreover, we reuse the pre-trained MT attention module in ST, so we can leverage the alignment information learned in pre-training.\nSince the text encoder consumes word embeddings of plausible texts in MT task but uses speech encoder outputs in ST task, another question is how one guarantees the speech encoder outputs are consistent with the word embeddings. We further modify our model to achieve semantic consistency and length consistency. Specifically, (1) the projection matrix at the CTC classification layer for ASR is shared with the word embedding matrix, ensuring that they are mapped to the same latent space, and (2) the length of the speech encoder output is proportional to the length of the input frame, so it is much longer than a natural sentence. To bridge the length gap, source sentences in MT are lengthened by adding word repetitions and blank tokens to mimic the CTC output sequences.\nWe conduct comprehensive experiments on the IWSLT18 speech translation benchmark BIBREF1, demonstrating the effectiveness of each component. Our model is significantly better than previous methods by 3.6 and 2.2 BLEU scores for the subword-level decoding and character-level decoding strategies, respectively.\nOur contributions are three-folds: 1) we shed light on why previous ST models cannot sufficiently utilize the knowledge learned from the pre-training process; 2) we propose a new ST model, which alleviates shortcomings in existing methods; and 3) we empirically evaluate the proposed model on a large-scale public dataset.\nWe further modify our model to achieve semantic consistency and length consistency.

However, we show that results for state of the art models sometimes end up within error margins from one another, so one has to report the margins to compare the results rigorously. More importantly, one can see that there is an inherent trade-off between these two performance metrics. This trade-off is not only visible across models but is also present for the same retrained architecture. Therefore, improving one of the two metrics is not enough to confidently state that one system solves the style-transfer problem better than the other. One has to report error margins after several consecutive retrains and instead of comparing one of the two metrics has to talk about Pareto-like optimization that would show confident improvement of both.\nOn Figure FIGREF1 one can see that the outcomes for every single rerun differ significantly.

        "evidence": "Bernoulli's principle is a key concept in fluid dynamics that relates pressure, speed and height. Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.  The principle is named after the Swiss mathematician and physicist Daniel Bernoulli, who published it in his book Hydrodynamica in 1738.Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler in 1752 who derived Bernoulli's equation in its usual form. The principle is only applicable for isentropic flows: when the effects of irreversible processes (like turbulence) and non-adiabatic processes (e.g. thermal radiation) are small and can be neglected.\nBernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same at all points that are free of viscous forces. This requires that the sum of kinetic energy, potential energy and internal energy remains constant. Thus an increase in the speed of the fluid—implying an increase in its kinetic energy (dynamic pressure)—occurs with a simultaneous decrease in (the sum of) its potential energy (including the static pressure) and internal energy. If the fluid is flowing out of a reservoir, the sum of all forms of energy is the same because in a reservoir the energy per unit volume (the sum of pressure and gravitational potential ρ g h) is the same everywhere.\nBernoulli's principle can also be derived directly from Isaac Newton's second Law of Motion. If a small volume of fluid is flowing horizontally from a region of high pressure to a region of low pressure, then there is more pressure behind than in front. This gives a net force on the volume, accelerating it along the streamline.\nFluid particles are subject only to pressure and their own weight. If a fluid is flowing horizontally and along a section of a streamline, where the speed increases it can only be because the fluid on that section has moved from a region of higher pressure to a region of lower pressure; and if its speed decreases, it can only be because it has moved from a region of lower pressure to a region of higher pressure. Consequently, within a fluid flowing horizontally, the highest speed occurs where the pressure is lowest, and the lowest speed occurs where the pressure is highest.",

Each transformer encoder contains multi-head self-attention layers that provide ability to learn multiple attention feature of each word from their bidirectional context. The transformer and its self-attention mechanism are proposed by BIBREF8. This self-attention mechanism can be interpreted as a key-value mapping given query. By given the embedding vector for token input, the query ($Q$), key ($K$) and value ($V$) are produced by the projection from each three parameter matrices where $W^Q \\in \\mathbb {R}^{d_{{\\rm model}} \\times d_{k}}, W^K \\in \\mathbb {R}^{d_{\\rm model} \\times d_{k}}$ and $W^V \\in \\mathbb {R}^{d_{\\rm model} \\times d_{v}}$. The self-attention BIBREF8 is formally represented as:\nThe $ d_k = d_v = d_{\\rm model} = 1024$ in BERT large version and 768 in BERT base version. Once model can extract attention feature, we can extend one self-attention into multi-head self-attention, this extension makes sub-space features can be extracted in same time by this multi-head configuration. Overall, the multi-attention mechanism is adopt for each transformer encoder, and several of encoder layer will be stacked together to form a deep transformer encoder.\nFor the model input, BERT allow us take one sentence as input sequence or two sentences together as one input sequence, and the maximum length of input sequence is 512. The way that BERT was designed is for giving model the sentence-level and token-level understanding. In two sentences case, a special token ([SEP]) will be inserted between two sentences. In addition, the first input token is also a special token ([CLS]), and its corresponding ouput will be vector place for classification during fine-tuning. The outputs of the last encoder layer corresponding to each input token can be treated as word representations for each token, and the word representation of the first token ([CLS]) will be consider as classification (output) representation for further fine-tuning tasks. In BERT, this vector is denoted as $C \\in \\mathbb {R}^{d_{\\rm model}} $, and a classification layer is denoted as $ W \\in \\mathbb {R}^{K \\times d_{\\rm model}}$, where $K$ is number of classification labels.

        "evidence": "Deep learning models have been widely used in many natural language processing (NLP) tasks. A major challenge is how to design and learn the semantic composition function while modeling a text sequence. The typical composition models involve sequential BIBREF0 , BIBREF1 , convolutional BIBREF2 , BIBREF3 , BIBREF4 and syntactic BIBREF5 , BIBREF6 , BIBREF7 compositional models.\nIn spite of their success, these models have two major limitations. First, they usually use a shared composition function for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Second, different composition functions are learned from scratch in different tasks. However, given a certain natural language, its composition functions should be the same (on meta-knowledge level at least), even if the tasks are different.\nTo address these problems, we need to design a dynamic composition function which can vary with different positions and contexts in a sequence, and share it across the different tasks. To share some meta-knowledge of composition function, we can adopt the multi-task learning BIBREF8 . However, the sharing scheme of most neural multi-task learning methods is feature-level sharing, where a subspace of the feature space is shared across all the tasks. Although these sharing schemes are successfully used in various NLP tasks BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , they are not suitable to share the composition function.\nIn this paper, inspired by recent work on dynamic parameter generation BIBREF15 , BIBREF16 , BIBREF17 , we propose a function-level sharing scheme for multi-task learning, in which a shared meta-network is used to learn the meta-knowledge of semantic composition among the different tasks. The task-specific semantic composition function is generated by the meta-network. Then the task-specific composition function is used to obtain the task-specific representation of a text sequence. The difference between two sharing schemes is shown in Figure 1 . Specifically, we use two LSTMs as meta and basic (task-specific) network respectively. The meta LSTM is shared for all the tasks. The parameters of the basic LSTM are generated based on the current context by the meta LSTM, therefore the composition function is not only task-specific but also position-specific. The whole network is differentiable with respect to the model parameters and can be trained end-to-end.\nWe demonstrate the effectiveness of our architectures on two kinds of NLP tasks: text classification and sequence tagging. Experimental results show that jointly learning of multiple related tasks can improve the performance of each task relative to learning them independently.\nOur contributions are of three-folds:\nThe task-specific semantic composition function is generated by the meta-network.",

She confides in Poirot that she will soon be murdered, and that nothing can be done to stop it; after refusing Poirot's assistance, Jennie departs in distress, and Poirot is unable to find out anymore information from the staff about Jennie or her address. After returning to the guest house where he is staying, Poirot describes the events to Edward Catchpool, an officer at Scotland Yard - Catchpool reveals that he has spent the day investigating three murders at the luxurious Bloxham Hotel; two women and a man, all in separate rooms, were found dead earlier in the evening, each with a monogrammed cufflink (with the letters 'PJI') in their mouths.\n\nThe following day, Poirot and Catchpool attend the scene of the crime where they discover more details about the victims with the hotel's owner, Luca Lazzari; the victims (Harriet Sippel, Ida Gransbury and Richard Negus) had all arrived at the hotel separately on the same day; each victim was found in their locked hotel rooms; the murders occurred between 19:15 and 20:10 (all three victims were seen alive at 19:15 by hotel staff); Mr. Negus had booked the rooms for all three victims and paid for them ahead of time; a junior clerk saw Mr. Negus in the reception area 15 minutes after room service was provided for the victims. Later on, it's revealed that all three victims had lived in a village called Great Holling, and that Mr. Negus had been engaged to Ida - in addition, Richard had left Great Holling in 1913 after the deaths of the village vicar and his wife, Patrick and Frances Ives. Poirot sends Catchpool to Great Holling to discover more information about the victims. After arriving in the village, Catchpool meets Margaret Ernst, widow of the most recent vicar for the village. After some reluctance, Margaret relays to Catchpool the events of 1913. The vicar's maid had told Harriet Sippel a rumour that the vicar was taking money from villagers to help them 'communicate' with deceased loved ones. Harriet spread the rumour around the village, with the support of Ida and Mr. Negus. The rumours spiralled until there were calls to remove Ives as Vicar, and Frances' health declined as a result. Eventually, unable to bear the rumours any longer, Frances took her own life, with the heartbroken vicar following shortly afterwards. After some questioning, Catchpool learns that the maid who told the original lie was Jennie Hobbs - the same Jennie that Poirot has been searching for all this time.\n\nMeanwhile, as Catchpool is leaving London, Poirot arranges to meet with Nancy Ducane, a famous artist who was seen to be leaving the hotel shortly after the murders - Nancy was also mentioned in Margaret's story as the villager seen to be visiting the church at night with Ives. During the visit, Nancy recognises the names of various Great Holling residents but refuses to provide anymore details. However, Poirot and Constable Stanley Beer find a pair of keys that correspond to two of the victims' hotel rooms. Whilst visiting the home of Nancy's friend to confirm her alibi, Poirot notes several details from different paintings within the house. Shortly after returning home, Poirot learns from Scotland Yard that a fourth murder has occurred at the Bloxham - with Catchpool, the two gentlemen return to the hotel - they find a pool of blood, a monogrammed cufflink and (to Poirot's dismay) Jennie's hat within the room. After returning to their guest house, Poirot and Catchpool are visited by Nancy, who confesses her connection to the events in Great Holling; she was having an affair with Ives, and Jennie - who was also in love with the vicar - had spread the rumours out of jealousy. Nancy's attempts to placate the villagers by telling the truth were dismissed, and indeed further ruined the reputation of the vicar. The following day, Poirot takes Catchpool to visit the address of Samuel Kidd, the witness who saw Nancy at the hotel. However, instead of Samuel, they are greeted by Jennie Hobbs who - Poirot reveals - was formerly engaged to Samuel before she met the vicar. After listening to her testimony, Poirot and Catchpool return to Great Holling in response to a serious attack on Margaret - after speaking with the village doctor, Ambrose Flowerday, Poirot decides to return to the Bloxham one last time to resolve the case.\n\nAt the hotel, Poirot gathers the hotel staff and suspects together to reveal the solution; Nancy Ducane and Jennie Hobbs (with Kidd's assistance) had conspired to kill the three victims. Nancy & Kidd had impersonated Harriet & Mr. Negus at 19.15, and Kidd was the gentleman seen by the clerk at the front desk at 19.30. Nancy confesses to the crimes, but is fatally stabbed by Jennie. At Scotland Yard, Jennie, confesses her side of the story; In 1913, the rumour that Jennie had created was actually intended to save Ives from the scandal of his affair with Nancy. Harriet was convinced that the vicar could help her speak to her dead husband, and upon being refused, viciously spread the rumour in Great Holling. Years later, Mr. Negus contacted Jennie out of remorse for his actions, and the two people hatched a plan to kill all four guilty parties involved in the rumour. Mr. Negus and Jennie would lure Harriet and Ida to the Bloxham under false pretenses and poison them separately; Mr. Negus would then poison Jennie, and finally himself. However, Jennie secretly revealed the plan to Nancy to avoid her own death, and convinced Richard to die before her so that she could find justice against Nancy. Mr. Negus agreed to this plan, and Jennie arranged the scene to look like Mr. Negus had killed himself. Jennie had killed Nancy after she revealed at the meeting that her relationship with Ives had been a physical one, rather than the chaste romance that Jennie had been led to believe.\n\nFour days after Jennie and Kidd's arrest, Poirot and Catchpool receive a letter from Dr Flowerday and Margaret Ernst; they have harboured feelings for each other for years, and after Poirot's intervention have decided to marry.",

        "question": "Please write a summary of the kinds of vehicles that are used for ambulances.",
        "evidence": "Vehicle types\nIn North America (US and Canada), there are four types of ambulances. There are Type I, Type II, Type III, and Type IV. Type I is based upon a heavy truck chassis-cab with a custom rear compartment that is often referred to as a \"box\" or \"module.\" Type I ambulances are primarily used for Advanced Life Support (ALS), also referred to as Mobile Intensive Care Unit (MICU) in some jurisdictions, and rescue work. A Type II ambulance is based on a commercial heavy-duty van with few modifications except for a raised roof and a secondary air conditioning unit for the rear of the vehicle. These types of ambulances are primarily used for Basic Life Support (BLS) and transfer of patients but it is not uncommon to find them used for advanced life support and rescue. Type III is a van chassis-cab but with a custom-made rear compartment and has the same uses as Type I ambulances. Type IV is for smaller ad hoc patient transfer that use smaller utility vehicles in which passenger vehicles and trucks would have difficulty in traversing, such as large industrial complexes, commercial venues, and special events with large crowds; they generally do not fall under Federal Regulations.\n\nAmbulances can be based on many types of vehicle although emergency and disaster conditions may lead to other vehicles serving as makeshift ambulances:\n\n\nA modern American ambulance built on the chassis of a Ford F-450 truck, with extensive external storage\n\nMany modern Canadian and European ambulances are built on the Mercedes-Benz Sprinter chassis. Some, like this Niagara Region example, use custom rear compartments.\nVan or pickup truck – A typical general-purpose ambulance is based on either the chassis of a van (vanbulance) or a light-duty truck. This chassis is then modified to the designs and specifications of the purchaser. Vans may either retain their original body and be upfitted inside, or may be based on a chassis without the original body with a modular box body fitted instead. Those based on pickup trucks almost always have modular bodies. Those vehicles intended for especially intensive care or require a large amount of equipment to be carried may be based on medium-duty trucks.\nCar – Used either as a fly-car for rapid response or to transport patients who can sit, these are standard car models adapted to the requirements of the service using them. Some cars are capable of taking a stretcher with a recumbent patient, but this often requires the removal of the front passenger seat, or the use of a particularly long car. This was often the case with early ambulances, which were converted (or even serving) hearses, as these were some of the few vehicles able to accept a human body in a supine position. Some operators use modular-body transport ambulances based on the chassis of a minivan and station wagon.\nMotorcycle and motor scooter – In urban areas, these may be used for rapid response in an emergency as they can travel through heavy traffic much faster than a car or van. Trailers or sidecars can make these patient transporting units. See also motorcycle ambulance.\n\nPatient being loaded into a medical helicopter\nBicycle – Used for response, but usually in pedestrian-only areas where large vehicles find access difficult. Like the motorcycle ambulance, a bicycle may be connected to a trailer for patient transport, most often in the developing world. See also cycle responder.\nAll-terrain vehicle (ATV) – for example quad bikes; these are used for response off-road, especially at events. ATVs can be modified to carry a stretcher, and are used for tasks such as mountain rescue in inaccessible areas.\n\nGolf Cart converted into an ambulance\nGolf cart or Neighborhood Electric Vehicle – Used for rapid response at events or on campuses. These function similarly to ATVs, with less rough terrain capability, but with less noise.\nHelicopter – Usually used for emergency care, either in places inaccessible by road, or in areas where speed is of the essence, as they are able to travel significantly faster than a road ambulance. Helicopter and fixed-wing ambulances are discussed in greater detail at air ambulance.\nFixed-wing aircraft – These can be used for either acute emergency care in remote areas (such as in Australia, with the 'Flying Doctors'), for patient transport over long distances (e.g. a re-patriation following an illness or injury in a foreign country), or transportation between distant hospitals. Helicopter and fixed-wing ambulances are discussed in greater detail at air ambulance.\nBoat – Boats can be used to serve as ambulances, especially in island areas or in areas with a large number of canals, such as the Venetian water ambulances. Some lifeboats or lifeguard vessels may fit the description of an ambulance as they are used to transport a casualty.\nBus – In some cases, buses can be used for multiple casualty transport, either for the purposes of taking patients on journeys, in the context of major incidents, or to deal with specific problems such as drunken patients in town centres. Ambulance buses are discussed at greater length in their own article.\nTrailer – In some instances a trailer, which can be towed behind a self-propelled vehicle can be used. This permits flexibility in areas with minimal access to vehicles, such as on small islands.\nHorse and cart – Especially in developing world areas, more traditional methods of transport include transport such as horse and cart, used in much the same way as motorcycle or bicycle stretcher units to transport to a local clinic.\nFire engine – Fire services (especially in North America) often train firefighters to respond to medical emergencies and most apparatuses carry at least basic medical supplies. By design, most apparatuses cannot transport patients unless they can sit in the cab.",
        "answer": "The most common types of vehicle used as an ambulance are cars, vans or pickup trucks. Depending on many factors, such as accessibility to the patient and/or medical services or the urgency of treatment, other types of vehicles are used as well, including: bicycles, all-terrain vehicles, golf carts, helicopters, fixed-wing aircraft, boats, busses, trailers, horse and cart, and fire engines.",

        "evidence": "",
        "answer": "First, it is possible that Jill may have poor posture, which creates muscular fatigue, joint compression, and stresses the discs that cushion her vertebrae. She can focus on having better posture while sitting, keeping her spine straight, hips level, shoulders level, and head erect and straight. She should also balance her weight equally on both feet. If she needs to sit for extended periods of time, she can change her position often; she should periodically walk around and gently perform stretches for her muscles to relieve tension. Secondly, outside of things she could do while sitting, she can consider performing exercises for lower back care. For example, she can perform exercises such as pelvic tilts, trunk flex, partial sit-ups, or even engage in things like yoga or pilates to better strengthen her lower back as well as improve flexibility. Both of these will help reduce her lower back aches.",

        "evidence": "",
        "answer": "Music is often broken down into fundamental components using this model of understanding: Melody, Harmony, and Rhythm.  Of these three it is true rhythm is the easiest for computers to do a near perfect job of imitating.  Advancements in technology from the first drum machines that appeared in the 1970s, to widely used beat machines of the 1990's, to software music composition suites of today means you now have a lot of control at youf finger tips to create rhythm. You can now create drum beats that account for tempo variations, pitch variations, changes in dynamics, how close the drum pattern stays on beat, the type of hit the beat should be using, what the tension on the drum heads should sound like, how much rebound against the drum head is present, velocity of the stick, the simulated room size of where the drum kit is located,  how much resonance is vibrating in the drum kit itself, tonal variance of the wood shells used to create the drum beat and many more.   These advancements make software drumbeats realistic, and indistinguishable from their human counterparts yet the role of the drummer in modern music could not be more important.  Humans love live music, and very few commercially successful live musical acts do not use a live drummer.  Even rap and hip hop--two musical genres famous for ushering in the area of \"sampled\" drum beats, and \"sampled song loops\"-- often will have a live drummer on stage despite the ease of which the music can be broadcast loudly without requiring one.   The reason is simple: live drums and the musicians who perform using them are both visually and sonically exciting.  There are genres where a drummer is not provided such as \"DJ Couture\" and \"Electronic Dance music\" (or EDM) but they are the exceptions and not the rule. From the earliest humans banging rocks and sticks together, to the modern drums of today the future of the live drummer in music has never been brighter.",

Bligh used his memory of navigation charts to plan a course westward to the Dutch colony of Timor.  \n\nThey initially tried stopping at an island to gather supplies.  The island was inhabited, however, and they were attacked.  One crew member was killed and the rest barely escaped.  From then on they dared not stop at any island until reaching the Great Barrier Reef of Australia (then called New Holland by the Europeans).\n\nIn a remarkable achievement of seamanship, Bligh and his men sailed and rowed their open boat for 41 days over a distance of 3618 miles, in sometimes harsh weather conditions.  Food and drink had to be strictly rationed, and the men suffered greatly from hunger and thirst.  Except for the death of the crewman at the hands of the islanders, all the remaining crew reached Timor alive.  Sadly, some men died of disease contracted at the colony town of Batavia or on the final return voyage to Europe.  Of the original nineteen men set adrift by the Bounty mutineers, twelve returned alive to England.\n\nBligh continued his career in the British Navy.  He was assigned a new ship and once again sailed to Tahiti take breadfruit to British colonies in the Caribbean.  This time, the mission was completed successfully.  Bligh commanded additional ships, including fighting in several major naval battles.  In 1805, Bligh was appointed Governor of New South Wales.  He ended his British Naval career as a Vice Admiral.

        "evidence": "Categories such as animal or furniture are fundamental cognitive building blocks allowing humans to efficiently represent and communicate the complex world around them. Concepts (e.g., dog, table) are grouped into categories based on shared properties pertaining, for example, to their behavior, appearance, or function. Categorization underlies other cognitive functions such as perception BIBREF0 , BIBREF1 or language BIBREF2 , BIBREF3 , and there is evidence that categories are not only shaped by the world they represent, but also by the language through which they are communicated BIBREF4 , BIBREF5 . Although mental categories exist across communities and cultures, their exact manifestations differ BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . For example, American English speakers prefer taxonomic categorizations (e.g., mouse,squirrel) while Chinese speakers tend to prefer to categorize objects relationally (e.g., tree, squirrel; BIBREF7 ).\nGiven their prevalent function in human cognition, the acquisition and representation of categories has attracted considerable attention in cognitive science, and numerous theories have emerged BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . Empirical studies of category acquisition and representation, have been predominantly based on small-scale laboratory experiments. In a typical experiment, human subjects are presented with small sets of often artificial concepts, such as binary strings BIBREF14 or colored shapes BIBREF15 , with strictly controlled features BIBREF16 , BIBREF17 , BIBREF18 . Hypotheses and principles of human categorization are established based on the processes and characteristics of the categorizations produced by the participants. The distribution of subjects participating in such studies is often skewed towards members of cultural and socioeconomic groups which are prevalent in the environment where the research is conducted, and typically consists to a large proportion of western, educated, wealthy and English-speaking participants often sampled from the even more specific population of college students. The demographic and socioeconomic bias has been long recognized, and the question of how this bias might impact conclusions about human cognition in general BIBREF19 and category learning specifically is under active debate BIBREF9 . Although laboratory studies are invaluable for understanding categorization phenomena in a controlled environment, they are also expensive and time-consuming to conduct, and consequently problematic to scale.\nIn this work, we scale the investigation of category learning and representation along two axes: (1) the complexity of the learning environment, and consequently the richness of learnable concept and category representations, and (2) the diversity of languages and cultures considered in evaluation. We present a novel knowledge-lean, cognitively motivated Bayesian model which learns categories and their structured features jointly from large natural language text corpora in five diverse languages: Arabic, Chinese, English, French, and German. We approximate the learning environment using large corpora of natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Besides text corpora can cover arbitrarily semantically complex domains, and are available across languages, providing an ideal test environment for studying categorization at scale.\nFigure 1 illustrates example input to our model, and Figure 2 shows example categories and associated features as induced by our model from the English Wikipedia. Following prior work BIBREF21 , BIBREF22 , we create language-specific sets of stimuli, each consisting of a mention of target concept (e.g., apple), within its local linguistic context (e.g., {contains, seeds}; cf., Figure 1 ). We consider each stimulus an observation of the concept, i.e., the word referring to the concept is an instance of the concept itself, and its context words are a representation of its features. Our model infers categories as groups of concepts occurring with similar features; and it infers feature types as groups of features which co-occur with each other. The output of our model (cf., Figure 2 ) are categories as clusters of concepts, each associated with a set of feature types, i.e., thematically coherent groups of features. We train a separate model on each of our target languages, each time presenting the model with input stimuli from the relevant language.\nComputational models in general, and Bayesian models in particular, allow to investigate hypotheses about cognitive phenomena by systematically modifying the learning mechanism or available input while observing the learning outcome. Bayesian models have been applied to a variety of cognitive phenomena BIBREF23 , BIBREF24 , BIBREF25 , and category acquisition is no exception. Following from Anderson's BIBREF14 , BIBREF26 , BIBREF27 seminal work, a number of models have been developed, and tested in their ability to reproduce human behavior in laboratory settings by exposing the models to small sets of controlled inputs with restricted features. In this work we draw on the full potential of computational modeling by exposing our models to (a) more complex data reflecting the diversity of contexts in which concepts can be observed; and (b) a input data in different languages, shedding light on the applicability of computational cognitive models beyond the prevalent English test language.\nCategorization tasks in a laboratory environment typically involve stimuli with a small set of features which are relevant to the categorization target, eliminating the need to detect features, and discriminate them in their relevance. In the real world, however, concepts are observed in contexts and a substantial part of acquiring categorical knowledge involves learning which features are useful to discriminate among concepts. In fact, research has shown that humans learn features jointly with categories BIBREF28 , BIBREF29 and that these features are themselves structured so as to represent the diversity and complexity of the properties exhibited in the world BIBREF30 , BIBREF31 , BIBREF32 . Our novel model of category learning presented in this article, jointly learns categories and their structured features from large sets of informationally rich data.\nOur work exemplifies the opportunities that arise from computational models and large data sets for investigating the mechanisms with which conceptual representations emerge, as well as the representations themselves in a broader context. We simulate the acquisition of categories comprising hundreds of concepts by approximating the learning environment with natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , as well as human-like biases BIBREF33 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Text corpora are a prime example of naturally occurring large-scale data sets BIBREF34 , BIBREF35 , BIBREF36 . In analogy to real-world situations, they encapsulate rich, diverse, and potentially noisy, information. The wide availability of corpora allows us to train and evaluate cognitive models on data from diverse languages and cultures. We test our model on corpora from five languages, derived from the online encyclopedia Wikipedia in Arabic, Chinese, French, English, and German. Wikipedia is a valuable resource for our study because it (a) discusses concepts and their properties explicitly and can thus serve as a proxy for the environment speakers of a language are exposed to; and (b) allows us to construct corpora which are highly comparable in their content across languages, controlling for effects of genre or style.\nWe present a series of evaluations investigating the quality of the induced categories and features. Leveraging a reference comprising hundreds of concepts and more than 30 categories, we demonstrate that our model learns meaningful categories in all five target languages. We furthermore show, through crowd-sourced evaluations involving native speakers of each target language, that the induced feature types are (a) each thematically coherent and interpretable; and (b) are associated with categories in comprehensible ways. We discuss language-specific idiosyncrasies emerging from the induced representations.\nIn the remainder of this article, we first review related literature, before we present a cognitively motivated model for learning categories and their structured representations from large natural language corpora. We then evaluate the quality of the emerging representations, as well as the generalizability of our model across languages. Note that the primary goal of this work is not to characterize differences in categories and features arising from different languages (even though this would be an interesting avenue for future work). Rather, we aim to demonstrate the utility of large-scale naturalistic datasets for cognitive modeling, and to verify mechanisms of categorization known from laboratory studies at scale and across communities.\nIn this work, we scale the investigation of category learning and representation along two axes: (1) the complexity of the learning environment, and consequently the richness of learnable concept and category representations, and (2) the diversity of languages and cultures considered in evaluation.",

With a design consultant present, a site supervisor will review the plans and inspect your yard to ensure no modifications to the design are required. \n\nExcavation - The hole is dug and excess dirt is removed or dropped. The hole will be slightly larger and deeper than the finished pool, as the pool wall and bottom will take up some of this area.\n\nForm & Steel - Now that the pool has been dug, the hole is with reinforced with “steel rebar” to add the strength required for your pool.\n\nCity Inspections - After installing the steel rebar, an inspector will review your pool plans and inspect the job site to make sure everything is up to code. \n\nGunite - Crews will spray / apply the concrete that makes up your pool’s shell and steps. If your pool design includes any swim-outs, fountains, or a gunite spa, those elements will be part of this phase as well.\n\nBackfill & grade - Once the gunite is dried, it’s time to start backfilling around the walls and braces. The material from excavation is used to fill in the space between the newly constructed shell of the pool and the rest of the backyard.\n\nPlumbing Installation & Inspection - Plumbing crews begin installation, and dig trenches to lay pipe from your pool to the pool equipment. Any pipes for water features such as sprays, fountains, or rock falls will be installed, along with pool return lines and skimmer(s). After the plumbing installation, the city will inspect the work completed.\n\nSite Grade - Prior to placing the decking, the construction crew will level out and compact the sub-base preparing for the patio.\n\nTile & Coping Installation - Tile crews will install your pool’s waterline tile and coping. Additional work may also be performed during this phase by a different set of crews if rock is used in your pool’s design. If your pool design requires a retaining wall at the edge of any part of your deck, it will be constructed at this time. \n\nDeck Installation - Crews will form the shape and sand your deck and any planter areas. After this process is complete chosen rock or tile finish is applied. \n\nElectrical - Pre-Electrical Equipment Hook Up: Installing your pool pump, filter, and gas heater (if applicable). Run the conduit for the main electric supply used by your pool equipment. They will also install lighting and any wiring necessary for your pool. City inspection at this time as well.\n\nScreening - If you opted in for a screen, footers are poured and screen is constructed.\nPool Plaster - Prepare the concrete surface of your swimming pool, and then apply your pool’s finish and fill the pool with water – finishes cured underwater.  The water will need to stay on once it is started, without interruption, until your pool is full. Your pool will be considered completely full once the water reaches halfway up the tile line (middle of your waterline tile).\n\nClean up & inspection - During this phase, remove any trash that was created during the construction of your pool, and also complete the final grade of your yard. In most communities, an inspector from your city will inspect your pool area to ensure it is safe to use and everything has been properly completed.\n\nPool School - When the pool is balanced a Service Department will contact you to schedule an orientation. This orientation will answer any questions you may have about your new pool, as well as show you how to properly use your pool equipment.\n\nSWIM!",

Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nWe propose a fast adaptation method for obtaining a bilingual BERTBASE of English and a target language within a day using one Tesla V100 16GB GPU (§3).",

        "question": "What weakness could supervised models show if they are used for datasets not well-balanced?",
        "answer": "Supervised models may latch on to spurious features of such datasets",
        "evidence": "Supervised learning is frequently used to scale up analyses. For example, BIBREF42 wanted to analyze the motivations of Movember campaign participants. By developing a classifier based on a small set of annotations, they were able to expand the analysis to over 90k participants.\nThe choice of supervised learning model is often guided by the task definition and the label types. For example, to identify stance towards rumors based on sequential annotations, an algorithm for learning from sequential BIBREF43 or time series data BIBREF44 could be used. The features (sometimes called variables or predictors) are used by the model to make the predictions. They may vary from content-based features such as single words, sequences of words, or information about their syntactic structure, to meta-information such as user or network information. Deciding on the features requires experimentation and expert insight and is often called feature engineering. For insight-driven analysis, we are often interested in why a prediction has been made and features that can be interpreted by humans may be preferred. Recent neural network approaches often use simple features as input (such as word embeddings or character sequences), which requires less feature engineering but make interpretation more difficult.\nSupervised models are powerful, but they can latch on to spurious features of the dataset. This is particularly true for datasets that are not well-balanced, and for annotations that are noisy. In our introductory example on hate speech in Reddit BIBREF0 , the annotations are automatically derived from the forum in which each post appears, and indeed, many of the posts in the forums (subreddits) that were banned by Reddit would be perceived by many as hate speech. But even in banned subreddits, not all of the content is hate speech (e.g., some of the top features were self-referential like the name of the subreddit) but a classifier would learn a high weight for these features.\nEven when expert annotations are available on the level of individual posts, spurious features may remain. BIBREF45 produced expert annotations of hate speech on Twitter. They found that one of the strongest features for sexism is the name of an Australian TV show, because people like to post sexist comments about the contestants. If we are trying to make claims about what inhibits or encourages hate speech, we would not want those claims to be tied to the TV show's popularity. Such problems are inevitable when datasets are not well-balanced over time, across genres, topics, etc. Especially with social media data, we lack a clear and objective definition of `balance' at this time.\nThe risk of supervised models latching on to spurious features reinforces the need for interpretability. Although the development of supervised models is usually performance driven, placing more emphasis on interpretability could increase the adoption of these models in insight-driven analyses. One way would be to only use models that are already somewhat interpretable, for example models that use a small number of human-interpretable features. Rather than imposing such restrictions, there is also work on generating post-hoc explanations for individual predictions (e.g., BIBREF46 ), even when the underlying model itself is very complex.\nSupervised models are powerful, but they can latch on to spurious features of the dataset. This is particularly true for datasets that are not well-balanced, and for annotations that are noisy.",

        "evidence": "Reading Comprehension (RC) has become a central task in natural language processing, with great practical value in various industries. In recent years, many large-scale RC datasets in English BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6 have nourished the development of numerous powerful and diverse RC models BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11. The state-of-the-art model BIBREF12 on SQuAD, one of the most widely used RC benchmarks, even surpasses human-level performance. Nonetheless, RC on languages other than English has been limited due to the absence of sufficient training data. Although some efforts have been made to create RC datasets for Chinese BIBREF13, BIBREF14 and Korean BIBREF15, it is not feasible to collect RC datasets for every language since annotation efforts to collect a new RC dataset are often far from trivial. Therefore, the setup of transfer learning, especially zero-shot learning, is of extraordinary importance.\nExisting methods BIBREF16 of cross-lingual transfer learning on RC datasets often count on machine translation (MT) to translate data from source language into target language, or vice versa. These methods may not require a well-annotated RC dataset for the target language, whereas a high-quality MT model is needed as a trade-off, which might not be available when it comes to low-resource languages.\nIn this paper, we leverage pre-trained multilingual language representation, for example, BERT learned from multilingual un-annotated sentences (multi-BERT), in cross-lingual zero-shot RC. We fine-tune multi-BERT on the training set in source language, then test the model in target language, with a number of combinations of source-target language pair to explore the cross-lingual ability of multi-BERT. Surprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese. Recent studies BIBREF17, BIBREF12, BIBREF18 show that cross-lingual language models have the ability to enable preliminary zero-shot transfer on simple natural language understanding tasks, but zero-shot transfer of RC has not been studied. To our knowledge, this is the first work systematically exploring the cross-lingual transferring ability of multi-BERT on RC tasks.\nWe fine-tune multi-BERT on the training set in source language, then test the model in target language, with a number of combinations of source-target language pair to explore the cross-lingual ability of multi-BERT.",

The name Doodle is also used to describe this breed. The name Goldendoodle is derived from \"Golden\" (from Golden Retriever) and \"Labradoodle\" (itself a portmanteau of Labrador Retriever and a Poodle). Deliberately breeding Poodles with Golden Retrievers actually preceded the 1990s. An example of this was done by Monica Dickens, the great-granddaughter of Charles Dickens, who crossed the two breeds in 1969. The cross can result in a healthier animal than both parent breeds.\n\nThe first litter of Mini Goldendoodles was created by Amy Lane of Fox Creek Farm in Berkeley Springs, WV. The litter arrived on 1/11/02 and consisted of 10 puppies.[citation needed] Two of these puppies were retained for future breeding and one of them produced the first litter of F1B Mini Goldendoodles. The term \"Goldendoodle\" was coined by Amy Lane.[citation needed] Amy Lane also created the first, and to this date, the only kennel club for Goldendoodles called the Goldendoodle Association of North America, Inc. This is a non-profit organization that guides the development of the Goldendoodle and also provides a registration service to document the lineage of Goldendoodles.[citation needed]\n\nThe original aim of the Goldendoodle's breeders was to produce an alternative to the popular Labradoodle. Initially Goldendoodles were only bred from standard-sized Poodles, but designer breeders also started using small varieties of Poodles to create a smaller crossbreed. As they are a hybrid cross, they are not recognized by the AKC or British Kennel Clubs. Goldendoodles have been developed beyond the F1 (Golden Retriever crossed with a Poodle) and are now available in deeper generations created by crossing two Goldendoodles. These are called multigenerational or multigen Goldendoodles.",

Our second method involves shallow syntactic features obtained automatically on downstream task data. Neither approach leads to a significant gain on any of the four downstream tasks we considered relative to ELMo-only baselines. Further analysis using black-box probes confirms that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo's embeddings.

Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.\nThe presence of either a positive or negative electric charge produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. In most applications, a force acts on a charge with a magnitude given by Coulomb's law. Electric potential is typically measured in volts.\nElectricity is at the heart of many modern technologies, being used for:\nElectric power where electric current is used to energise equipment;\nElectronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.\nElectrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the 17th and 18th centuries. The theory of electromagnetism was developed in the 19th century, and by the end of that century electricity was being put to industrial and residential use by electrical engineers. The rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution. Electricity's extraordinary versatility means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation.

The main story arc concerns Harry's conflict with Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic and subjugate all wizards and Muggles (non-magical people).\n\nThe series was originally published in English by Bloomsbury in the United Kingdom and Scholastic Press in the United States. All versions around the world are printed by Grafica Veneta in Italy. A series of many genres, including fantasy, drama, coming-of-age fiction, and the British school story (which includes elements of mystery, thriller, adventure, horror, and romance), the world of Harry Potter explores numerous themes and includes many cultural meanings and references. According to Rowling, the main theme is death. Other major themes in the series include prejudice, corruption, and madness.\n\nSince the release of the first novel, Harry Potter and the Philosopher's Stone, on 26 June 1997, the books have found immense popularity, positive reviews, and commercial success worldwide. They have attracted a wide adult audience as well as younger readers and are widely considered cornerstones of modern literature. As of February 2023, the books have sold more than 600 million copies worldwide, making them the best-selling book series in history, and have been available in 85 languages. The last four books consecutively set records as the fastest-selling books in history, with the final instalment selling roughly 2.7 million copies in the United Kingdom and 8.3 million copies in the United States within twenty-four hours of its release.\n\nThe original seven books were adapted into an eight-part namesake film series by Warner Bros. Pictures. In 2016, the total value of the Harry Potter franchise was estimated at $25 billion, making Harry Potter one of the highest-grossing media franchises of all time. Harry Potter and the Cursed Child is a play based on a story co-written by Rowling.\n\nThe success of the books and films has allowed the Harry Potter franchise to expand with numerous derivative works, a travelling exhibition that premiered in Chicago in 2009, a studio tour in London that opened in 2012, a digital platform on which J. K. Rowling updates the series with new information and insight, and a pentalogy of spin-off films premiering in November 2016 with Fantastic Beasts and Where to Find Them, among many other developments. Themed attractions, collectively known as The Wizarding World of Harry Potter, have been built at several Universal Destinations & Experiences amusement parks around the world.",

        "question": "What did Michael Faraday and Georg Ohm do?",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nSocial media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience.

        "question": "Based on the following paragraph, list the Himalayan peaks that were surveyed and identified during the 19th century.",
        "evidence": "In 1802, the British began the Great Trigonometrical Survey of India to fix the locations, heights, and names of the world's highest mountains. Starting in southern India, the survey teams moved northward using giant theodolites, each weighing 500 kg (1,100 lb) and requiring 12 men to carry, to measure heights as accurately as possible. They reached the Himalayan foothills by the 1830s, but Nepal was unwilling to allow the British to enter the country due to suspicions of their intentions. Several requests by the surveyors to enter Nepal were denied.\n\nThe British were forced to continue their observations from Terai, a region south of Nepal which is parallel to the Himalayas. Conditions in Terai were difficult because of torrential rains and malaria. Three survey officers died from malaria while two others had to retire because of failing health.\n\nNonetheless, in 1847, the British continued the survey and began detailed observations of the Himalayan peaks from observation stations up to 240 km (150 mi) distant. Weather restricted work to the last three months of the year. In November 1847, Andrew Waugh, the British Surveyor General of India, made several observations from the Sawajpore station at the east end of the Himalayas. Kangchenjunga was then considered the highest peak in the world, and with interest, he noted a peak beyond it, about 230 km (140 mi) away. John Armstrong, one of Waugh's subordinates, also saw the peak from a site farther west and called it peak \"b\". Waugh would later write that the observations indicated that peak \"b\" was higher than Kangchenjunga, but given the great distance of the observations, closer observations were required for verification. The following year, Waugh sent a survey official back to Terai to make closer observations of peak \"b\", but clouds thwarted his attempts.\n\nIn 1849, Waugh dispatched James Nicolson to the area, who made two observations from Jirol, 190 km (120 mi) away. Nicolson then took the largest theodolite and headed east, obtaining over 30 observations from five different locations, with the closest being 174 km (108 mi) from the peak.\n\nNicolson retreated to Patna on the Ganges to perform the necessary calculations based on his observations. His raw data gave an average height of 9,200 m (30,200 ft) for peak \"b\", but this did not consider light refraction, which distorts heights. However, the number clearly indicated that peak \"b\" was higher than Kangchenjunga. Nicolson contracted malaria and was forced to return home without finishing his calculations. Michael Hennessy, one of Waugh's assistants, had begun designating peaks based on Roman numerals, with Kangchenjunga named Peak IX. Peak \"b\" now became known as Peak XV.\n\nIn 1852, stationed at the survey headquarters in Dehradun, Radhanath Sikdar, an Indian mathematician and surveyor from Bengal was the first to identify Everest as the world's highest peak, using trigonometric calculations based on Nicolson's measurements. An official announcement that Peak XV was the highest was delayed for several years as the calculations were repeatedly verified. Waugh began work on Nicolson's data in 1854, and along with his staff spent almost two years working on the numbers, having to deal with the problems of light refraction, barometric pressure, and temperature over the vast distances of the observations. Finally, in March 1856 he announced his findings in a letter to his deputy in Calcutta. Kangchenjunga was declared to be 8,582 m (28,156 ft), while Peak XV was given the height of 8,840 m (29,002 ft). Waugh concluded that Peak XV was \"most probably the highest in the world\". Peak XV (measured in feet) was calculated to be exactly 29,000 ft (8,839.2 m) high, but was publicly declared to be 29,002 ft (8,839.8 m) in order to avoid the impression that an exact height of 29,000 feet (8,839.2 m) was nothing more than a rounded estimate. Waugh is sometimes playfully credited with being \"the first person to put two feet on top of Mount Everest\".",

        "question": "What do the authors need to do once the universal encoder is constructed?",
        "answer": "The authors only need to train the pivot$rightarrow $target model and then test this model in source$rightarrow $target direction directly.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nOnce the universal encoder is constructed, the authors only need to train the pivot$rightarrow $target model and then test this model in source$rightarrow $target direction directly.",

In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nWe build our QA system based on a deep memory network.",

The original datasets such as WEIS and COPDAB were created by human coders who read news stories and coded events. Future datasets such as KEDS and Phil Schrodt's Levant dataset were created using automated coding software, such as KEDS or TABARI, and news stories download from content aggregators such as Lexis Nexis or Factiva. Both pieces of coding software made use of a technique referred to as shallow parsing BIBREF13 . Shallow parsing is best understood in contrast to a deep parsing method. In deep parsing, the entire syntactic structure of a sentence is used and understood. This syntactic structure includes things such as prepositional phrases, direct and indirect objects, and other grammatical structures. A shallow parse, however, focuses solely on, as the name implies, shallow aspects such as the part of speech of the words within the sentence.\nThe second major dimension that differentiates event datasets is how news content was acquired. For WEIS and COPDAB this was as simple as subscribing to the New York Times and coding from there. Later datasets, such as those created in conjunction with the Kansas Event Data Project, obtained historical content from aggregators, as mentioned above. This difficulty of this process changed at various points in time, with something like full automation possible at some points while human downloading of stories was required at others. There are often gaps in this historical content since the content aggregators catalog of different news services changes at various points and is often fairly limited. Updating datasets based on this type of content was also fairly labor intensive since new content had to be downloaded, cleaned, and run for every update. While orders of magnitude faster than human coding, this remained an involved process.\nTaken together, these two aspects of event data generation, shallow parsing and content acquisition, form the basis for where the next generation of political event data can improve upon previous efforts. In short, a shift to deep parsing based on relatively recent advances in open-source natural language processing software, combined with realtime acquisition of news content and aggressive strategies for acquiring historical material, provide the motivation for the next generation of political event data. The following section provides greater detail regarding the implementation of these new features.\nLater datasets, such as those created in conjunction with the Kansas Event Data Project, obtained historical content from aggregators, as mentioned above.

Depending on the time of year that they visit, different options would rank higher. \nFor example, if they arrive in the warmer months, say May to September, then an excellent place to start would be the freedom trail. This is a marked track that follows the famous ride of Paul Revere as the British forces arrived in Massachusetts Bay prior to the war of independence. During the warmer months, this path is nice to walk along as it will take your family along the landmarks of Boston, through the Boston Common, past the Quincy Markets, the Bunker Hill memorial, and through Boston's North End where some of the best Italian restaurants in the country can be found. In addition to this, Boston is home to two of the most prestigious universities in the world, Harvard University and the Massachusetts Institute of Technology. Free walking tours are available on both of these campuses which are located on the other side of the Charles river in the city of Cambridge. You can also go to a baseball game at the famous Fenway Park stadium to see the local team, the Red Socks play, as well as enjoy the city's shopping district along Newbury St. and the Prudential. \nIf, however, your family visits in the colder season, or worse during the peak of winter, Boston still has plenty of fun and enjoyable activities. You could take them to an ice hockey game at TD Gardens to watch the local team, the Bruins play. There are also Christmas and winter markets in the Sea Port district throughout the holidays.

        "question": "As per the following passage what did William Gilbert do?",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

        "question": "What does the new perspective for paraphrase identification focus on?",
        "answer": "It focuses on the aligned unmatched parts of a sentence pair.",
        "evidence": "Paraphrase identification is an important topic in artificial intelligence and this task justifies whether two sentences expressed in various forms are semantically similar, BIBREF0 . For example, “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend” are identified as paraphrase. This task directly benefits many industrial applications, such as plagiarism identification BIBREF0 , machine translation BIBREF1 and removing redundancy questions in Quora website BIBREF2 . Recently, there emerge many methods, such as ABCNN BIBREF3 , Siamese LSTM BIBREF2 and L.D.C BIBREF4 .\nConventionally, neural methodology aligns the sentence pair and then generates a matching score for paraphrase identification, BIBREF4 , BIBREF2 . Regarding the alignment, we conjecture that the aligned unmatched parts are semantically critical, where we define the corresponded word pairs with low similarity as aligned unmatched parts. For an example: “On Sunday, the boy runs in the yard” and “The child runs inside at the weekend”, the matched parts (i.e. (Sunday, weekend), (boy, child), run) barely make contribution to the semantic sentence similarity, but the unmatched parts (i.e. “yard” and “inside”) determine these two sentences are semantically dissimilar. For another example: “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend”, the aligned unmatched parts (i.e. “yard” and “outside”) are semantically similar, which makes the two sentences paraphrase. In conclusion, if the aligned unmatched parts are semantically consistent, the two sentences are paraphrase, otherwise they are non-paraphrase.\nTraditional alignment methods take advantage of attention mechanism BIBREF2 , which is a soft-max weighting technique. Weighting technique could pick out the most similar/dissimilar parts, but is weak in modeling the aligned unmatched parts, which are the crucial evidence to identify paraphrase. For the input sentences in Figure FIGREF1 , the weight between “Sunday” and “run” is lower than the weight between “yard” and “inside”, but the former weight is not the evidence of paraphrase/non-paraphrase, because the former two words that are most dissimilar should not be aligned for an inappropriate comparison.\nTo extract the aligned unmatched parts, in this paper, we embed Hungarian algorithm BIBREF5 into neural architecture as Hungarian layer (Algorithm SECREF7 ). Illustrated in Figure FIGREF1 , the alignment in sentence matching could be formulated as the task-assignment problem, which is tackled by Hungarian algorithm. Simply, Hungarian algorithm works out the theoretically optimal alignment relationship in an exclusive manner and the exclusiveness characterizes the aligned unmatched parts. For the example in Figure FIGREF1 , because Hungarian layer allocates the aligned pairs with exclusiveness, the matched parts (i.e (Sunday, weekend), (boy, child), run) are aligned firstly, then the word “yard” would be assigned to the word “inside” with a negative similarity, making a strong evidence for discrimination.\nSpecifically, our model performs this task in three steps. First, our model applies BiLSTM to parse the input sentences into hidden representations. Then, Hungarian layer leverages the hidden representations to extract the aligned unmatched parts. Last, we apply cosine similarity to metric the aligned unmatched parts for a final discrimination. Regarding the training process of Hungarian layer, we modify the back-propagation algorithm in both directions. In the forward pass, Hungarian layer works out the alignment relationship, according to which, the computational graph is dynamically constructed, as demonstrated in Figure FIGREF13 . Once the computational graph has been dynamically constructed, the backward propagation could be performed as usual in a conventional graph.\nWe conduct our experiments on the public benchmark dataset of “Quora Question Pairs” for the task of paraphrase identification. Experimental results demonstrate that our model outperforms other baselines extensively and significantly, which verifies our theory about the aligned unmatched parts and illustrates the effectiveness of our methodology.\nContributions. (1.) We offer a new perspective for paraphrase identification, which focuses on the aligned unmatched parts of two sentences. Accordingly, we propose the Hungarian layer to extract the aligned unmatched parts. The proposed method can achieve hard and exclusive alignments between two sequences, while we can learn parameters by end-to-end back-propagation. (2.) Our model outperforms other baselines extensively, verifying the effectiveness of our theory and method.\nOrganization. In Section 2, we survey the related work of paraphrase identification and dynamic differentiable computational graphs. In Section 3, we introduce our neural architecture. In Section 4, we conduct the experiments. In Section 5, we conclude our paper and publish our codes.\nWe offer a new perspective for paraphrase identification, which focuses on the aligned unmatched parts of two sentences.",

        "answer": "Once upon a time, there was a Frog. His name was Mr. Wilson. He lived in a small little twig house, on the side of a great big pond. He loved his little house. He especially loved how close he was to the water, which let him go out swimming, searching for yummy bugs to eat.\n\nOne night he was feeling lonely. It was just him in that tiny little house, by the great big pond. He looked up at the moon and wondered who else lived up there. He said, \"If only I could climb up to the moon, I would find friends and be happy\". Mr. Wilson noticed a grand and towering tree across the river. He thought to himself, \"If I can climb that tree, then I can make it up to the moon!\" \n\nSo he ventured out on a journey to make it up the tree. He rushed through the tall grass, moving quickly so the cats and dogs would not see him. When he made it to the tree he met an old squirrel friend named Ron. Ron was happy to help Mr. Wilson up the tree. So Mr. Wilson jumped on Ron's back and had a bouncy ride to the top. \n\nMr. Wilson made it to the top, but the tree needed to be taller! He still was so far away from the moon. Mr. Wilson put his head down and started to cry. He said, \"Ron, I can't get to the moon... I'll always be lonely!\". Ron responded, \"Look around Mr. Wilson, can't you see all the friends in the forest. You don't need to go to the moon! There is plenty of fun you can have right here!\". Mr. Wilson had a grand view of the whole forest and saw all the friends he could make. He smiled and was happy. He then knew that all along he had what he needed right where he was.

        "evidence": "Performing graph reasoning in large domains, such as predicting the relationship between two entities based on the input facts, is an important practical problem that arises in reasoning about molecular modeling, knowledge networks, and collections of objects in the physical world. The necessary inference rules are generally unknown and must be inferred from data, which in general are large. In this paper, we focus on learning neural networks for graph reasoning tasks. Consider the problem of learning a rule that explains the grandparent relationship. Given a dataset of labeled family relationship graphs, we aim to build machine-learning algorithms that can learn to predict a specific relationship (e.g., grandparent) based on other relationships, such as father(x, y) and mother(x, y).\nNeural Logic Machines (NLM; present a method for solving graph reasoning tasks with a structured neural network. NLMs keep track of hyperedge representations for all tuples consisting of up to B entities. Thus, they can infer more complex finitely-quantified logical relations than standard graph neural networks that only consider binary relationships between entities. However, there are two disadvantages of such a dense hypergraph representation. First, the training and inference of NLMs requires simultaneously considering all entities in a domain, such as all of the N people in a family relationship database. Second, they scale polynomially with respect to the number of entities considered in a single inference. Even inferring a single relation like grandparent requires O(N 3 ) time and space complexity. In practice, for large graphs, these limitations make the training and inference intractable and hinder the application of NLMs in large-scale real-world domains.\nTo address these two challenges, we present a novel framework, called Sparse and Local Neural Logic Machines (SpaLoc), for inducing sparse relational rules from data in large domains. Our key idea is to exploit locality and sparsity in data: determining a relationship between entities The overall pipeline of SpaLoc: a multi-layer neural network that applies to hypergraphs. I and V denote the index tensor and value tensor respectively. To facilitate training and inference in large domains, we employ a sub-graph sampling procedure and sparsification.\nusually only requires consideration of a small number of additional entities, and the resulting relation usually only holds for a small number of tuples of entities. Our contribution is three-fold. First, we develop a sparse tensor-based representation for representing hyperedge relationships among entities and making inferences about them. Second, during both training and inference, SpaLoc employs a sub-graph sampling technique based on an information-theoretic measure, information sufficiency, which quantifies the amount of information contained in a sub-graph with respect to whether a predicate is true for some tuple of entities. Since the sub-graph sampling may violate the closed-world assumption (i.e., the information in a sub-sampled graph may be insufficient in predicting the relationship between a pair of entities), we also use the information sufficiency measure to calibrate training labels. Third, to further speed up inference on large graphs, we encourage neural networks recover sparse relationships among objects by using a regularization term based on graph sparsity measurements.\nWe evaluate SpaLoc on two benchmarks: relational reasoning in synthetic datasets (family trees and general graph reasoning) and real-world knowledge-graph reasoning. First, we show that, with our sparsity regularization, the computation complexity for inference can be reduced to the same order as the optimal complexity, which significantly outperforms the base model NLM. Second, we show that training via sub-graph sampling and label calibration enables us to learn relational rules in real-world knowledge graphs with more than 10K nodes, whereas the original NLM can be barely applied to graphs with more than 100 nodes. Finally, SpaLoc achieves state-of-the-art performance on several real-world knowledge graph reasoning benchmarks.\nFigure 1: The overall pipeline of SpaLoc: a multi-layer neural network that applies to hypergraphs.

        "answer": "Trigger detection, argument detection and semantic post-processing.",
        "evidence": "Event Extraction in the Biomedical domain is a task that has gained more importance recently. Event Extraction goes beyond Relation Extraction. In Biomedical Event Extraction, events generally refer to a change in the state of biological molecules such as proteins and DNA. Generally, it includes detection of targeted event types such as gene expression, regulation, localisation and transcription. Each event type in addition can have multiple arguments that need to be detected. An additional layer of complexity comes from the fact that events can also be arguments of other events, giving rise to a nested structure. This helps to capture the underlying biology better BIBREF1 . Detecting the event type often involves recognising and classifying trigger words. Often, these words are verbs such as “activates”, “inhibits”, “phosphorylation” that may indicate a single, or sometimes multiple event types. In this section, we will discuss some of the successful models for Event Extraction in some detail.\nEvent Extraction gained a lot of interest with the availability of an annotated corpus with the BioNLP'09 Shared Task on Event Extraction BIBREF34 . The task involves prediction of trigger words over nine event types such as expression, transcription, catabolism, binding, etc. given only annotation of named entities (proteins, genes, etc.). For each event, its class, trigger expression and arguments need to be extracted. Since the events can be arguments to other events, the final output in general is a graph representation with events and named entities as nodes, and edges that correspond to event arguments. BIBREF33 present a pipeline based method that is heavily dependent on dependency parsing. Their pipeline approach consists of three steps: trigger detection, argument detection and semantic post-processing. While the first two components are learning based systems, the last component is a rule based system. For the BioNLP'09 corpus, only 5% of the events span multiple sentences. Hence the approach does not get affected severely by considering only single sentences. It is important to note that trigger words cannot simply be reduced to a dictionary lookup. This is because a specific word may belong to multiple classes, or may not always be a trigger word for an event. For example, “activate” is found to not be a trigger word in over 70% of the cases. A multi-class SVM is trained for trigger detection on each token, using a large feature set consisting of semantic and syntactic features. It is interesting to note that the hyperparameters of this classifier are optimised based on the performance of the entire end-to-end system.\nFor the second component to detect arguments, labels for edges between entities must be predicted. For the BioNLP'09 Shared Task, each directed edge from one event node to another event node, or from an event node to a named entity node are classified as “theme”, “cause”, or None. The second component of the pipeline makes these predictions independently. This is also trained using a multi-class SVM which involves heavy use of syntactic features, including the shortest dependency path between the nodes. The authors note that the precision-recall choice of the first component affects the performance of the second component: since the second component is only trained on Gold examples, any error by the first component will lead to a cascading of errors. The final component, which is a semantic post-processing step, consists of rules and heuristics to correct the output of the second component. Since the edge predictions are made independently, it is possible that some event nodes do not have any edges, or have an improper combination of edges. The rule based component corrects these and applies rules to break directed cycles in the graph, and some specific heuristics for different types of events. The final model gives a cumulative F-Score of 52% on the test set, and was the best model on the task.\n BIBREF35 note that previous approaches on the task suffer due to the pipeline nature and the propagation of errors. To counter this, they adopt a joint inference method based on Markov Logic Networks BIBREF36 for the same task on BioNLP'09. The Markov Logic Network jointly predicts whether each token is a trigger word, and if yes, the class it belongs to; for each dependency edge, whether it is an argument path leading to a “theme” or a “cause”. By formulating the Event Extraction problem using an MLN, the approach becomes computationally feasible and only linear in the length of the sentence. They incorporate hard constraints to encode rules such as “an argument path must have an event”, “a cause path must start with a regulation event”, etc. In addition, they also include some domain specific soft constraints as well as some linguistically-motivated context-specific soft constraints. In order to train the MLN, stochastic gradient descent was used. Certain heuristic methods are implemented in order to deal with errors due to syntactic parsing, especially ambiguities in PP-attachment and coordination. Their final system is competitive and comes very close to the system by BIBREF33 with an average F-Score of 50%. To further improve the system, they suggest leveraging additional joint-inference opportunities and integrating the syntactic parser better. Some other more recent models for Biomedical Event Extraction include BIBREF37 , BIBREF38 .\nTheir pipeline approach consists of three steps: trigger detection, argument detection and semantic post-processing",

        "evidence": "The avocado (Persea americana) is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated by Mesoamerican tribes more than 5,000 years ago. Then as now it was prized for its large and unusually oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator or avocado pear, is botanically a large berry containing a single large seed. Avocado trees are partly self-pollinating, and are often propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the tropical and Mediterranean climates of many countries. Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year.\n\nThe fruit of domestic varieties have smooth, buttery, golden-green flesh when ripe. Depending on the cultivar, avocados have green, brown, purplish, or black skin, and may be pear-shaped, egg-shaped, or spherical. For commercial purposes the fruits are picked while unripe and ripened after harvesting. The nutrient density and extremely high fat content of avocado flesh are useful to a variety of cuisines and are often eaten to enrich vegetarian diets.\n\nIn major production regions like Chile, Mexico and California the water demands of avocado farms place strain on local sources. Avocado production is also implicated in other externalities, including deforestation and human rights concerns associated with the partial control of their production in Mexico by organized crime. Global warming is expected to result in significant changes to the suitable growing zones for avocados, and place additional pressures on the locales in which they are produced due to heat waves and drought.",

        "question": "What argument components does the Toulmin model contain?",
        "answer": "They are claim, premise, backing, rebuttal, and refutation.",
        "evidence": "The goal of this study was to annotate documents on a detailed level with respect to an argumentation model. First, we will present the annotation scheme. Second, we will describe the annotation process. Finally, we will evaluate the agreement and draw some conclusions.\nGiven the theoretical background briefly introduced in section SECREF2 , we motivate our selection of the argumentation model by the following requirements. First, the scope of this work is to capture argumentation within a single document, thus focusing on micro-level models. Second, there should exist empirical evidence that such a model has been used for analyzing argumentation in previous works, so it is likely to be suitable for our purposes of argumentative discourse analysis in user-generated content. Regarding the first requirement, two typical examples of micro-level models are the Toulmin's model BIBREF36 and Walton's schemes BIBREF55 . Let us now elaborate on the second requirement.\nWalton's argumentation schemes are claimed to be general and domain independent. Nevertheless, evidence from the computational linguistics field shows that the schemes lack coverage for analyzing real argumentation in natural language texts. In examining real-world political argumentation from BIBREF56 , Walton.2012 found out that 37.1% of the arguments collected did not fit any of the fourteen schemes they chose so they created new schemes ad-hoc. Cabrio2013b selected five argumentation schemes from Walton and map these patterns to discourse relation categories in the Penn Discourse TreeBank (PDTB) BIBREF48 , but later they had to define two new argumentation schemes that they discovered in PDTB. Similarly, Song.et.al.2014 admitted that the schemes are ambiguous and hard to directly apply for annotation, therefore they modified the schemes and created new ones that matched the data.\nAlthough Macagno.Konstantinidou.2012 show several examples of two argumentation schemes applied to few selected arguments in classroom experiments, empirical evidence presented by Anthony.Kim.2014 reveals many practical and theoretical difficulties of annotating dialogues with schemes in classroom deliberation, providing many details on the arbitrary selection of the sub-set of the schemes, the ambiguity of the scheme definitions, concluding that the presence of the authors during the experiment was essential for inferring and identifying the argument schemes BIBREF57 .\nAlthough this model (refer to section SECREF21 ) was designed to be applicable to real-life argumentation, there are numerous studies criticizing both the clarity of the model definition and the differentiation between elements of the model. Ball1994 claims that the model can be used only for the most simple arguments and fails on the complex ones. Also Freeman1991 and other argumentation theorists criticize the usefulness of Toulmin's framework for the description of real-life argumentative texts. However, others have advocated the model and claimed that it can be applied to the people's ordinary argumenation BIBREF58 , BIBREF59 .\nA number of studies (outside the field of computational linguistics) used Toulmin's model as their backbone argumentation framework. Chambliss1995 experimented with analyzing 20 written documents in a classroom setting in order to find the argument patterns and parts. Simosi2003 examined employees' argumentation to resolve conflicts. Voss2006 analyzed experts' protocols dealing with problem-solving.\nThe model has also been used in research on computer-supported collaborative learning. Erduran2004 adapt Toulmin's model for coding classroom argumentative discourse among teachers and students. Stegmann2011 builds on a simplified Toulmin's model for scripted construction of argument in computer-supported collaborative learning. Garcia-Mila2013 coded utterances into categories from Toulmin's model in persuasion and consensus-reaching among students. Weinberger.Fischer.2006 analyze asynchronous discussion boards in which learners engage in an argumentative discourse with the goal to acquire knowledge. For coding the argument dimension, they created a set of argumentative moves based on Toulmin's model. Given this empirical evidence, we decided to build upon the Toulmin's model.\nIn this annotation task, a sequence of tokens (e.g. a phrase, a sentence, or any arbitrary text span) is labeled with a corresponding argument component (such as the claim, the grounds, and others). There are no explicit relations between these annotation spans as the relations are implicitly encoded in the pragmatic function of the components in the Toulmin's model.\nIn order to prove the suitability of the Toulmin's model, we analyzed 40 random documents from the gold data persuasive dataset using the original Toulmin's model as presented in section SECREF21 . We took into account sever criteria for assessment, such as frequency of occurrence of the components or their importance for the task. We proposed some modifications of the model based on the following observations.\nAuthors do not state the degree of cogency (the probability of their claim, as proposed by Toulmin). Thus we omitted qualifier from the model due to its absence in the data.\nThe warrant as a logical explanation why one should accept the claim given the evidence is almost never stated. As pointed out by BIBREF37 , “data are appealed to explicitly, warrants implicitly.” This observation has also been made by Voss2006. Also, according to [p. 205]Eemeren.et.al.1987, the distinction of warrant is perfectly clear only in Toulmin’s examples, but the definitions fail in practice. We omitted warrant from the model.\nRebuttal is a statement that attacks the claim, thus playing a role of an opposing view. In reality, the authors often attack the presented rebuttals by another counter-rebuttal in order to keep the whole argument's position consistent. Thus we introduced a new component – refutation – which is used for attacking the rebuttal. Annotation of refutation was conditioned of explicit presence of rebuttal and enforced by the annotation guidelines. The chain rebuttal–refutation is also known as the procatalepsis figure in rhetoric, in which the speaker raises an objection to his own argument and then immediately answers it. By doing so, the speaker hopes to strengthen the argument by dealing with possible counter-arguments before the audience can raise them BIBREF43 .\nThe claim of the argument should always reflect the main standpoint with respect to the discussed controversy. We observed that this standpoint is not always explicitly expressed, but remains implicit and must be inferred by the reader. Therefore, we allow the claim to be implicit. In such a case, the annotators must explicitly write down the (inferred) stance of the author.\nBy definition, the Toulmin's model is intended to model single argument, with the claim in its center. However, we observed in our data, that some authors elaborate on both sides of the controversy equally and put forward an argument for each side (by argument here we mean the claim and its premises, backings, etc.). Therefore we allow multiple arguments to be annotated in one document. At the same time, we restrained the annotators from creating complex argument hierarchies.\nToulmin's grounds have an equivalent role to a premise in the classical view on an argument BIBREF15 , BIBREF60 in terms that they offer the reasons why one should accept the standpoint expressed by the claim. As this terminology has been used in several related works in the argumentation mining field BIBREF7 , BIBREF61 , BIBREF62 , BIBREF11 , we will keep this convention and denote the grounds as premises.\nOne of the main critiques of the original Toulmin's model was the vague distinction between grounds, warrant, and backing BIBREF63 , BIBREF64 , BIBREF65 . The role of backing is to give additional support to the warrant, but there is no warrant in our model anymore. However, what we observed during the analysis, was a presence of some additional evidence. Such evidence does not play the role of the grounds (premises) as it is not meant as a reason supporting the claim, but it also does not explain the reasoning, thus is not a warrant either. It usually supports the whole argument and is stated by the author as a certain fact. Therefore, we extended the scope of backing as an additional support to the whole argument.\nThe annotators were instructed to distinguish between premises and backing, so that premises should cover generally applicable reasons for the claim, whereas backing is a single personal experience or statements that give credibility or attribute certain expertise to the author. As a sanity check, the argument should still make sense after removing backing (would be only considered “weaker”).\nWe call the model as a modified Toulmin's model. It contains five argument components, namely claim, premise, backing, rebuttal, and refutation. When annotating a document, any arbitrary token span can be labeled with an argument component; the components do not overlap. The spans are not known in advance and the annotator thus chooses the span and the component type at the same time. All components are optional (they do not have to be present in the argument) except the claim, which is either explicit or implicit (see above). If a token span is not labeled by any argument component, it is not considered as a part of the argument and is later denoted as none (this category is not assigned by the annotators).\nAn example analysis of a forum post is shown in Figure FIGREF65 . Figure FIGREF66 then shows a diagram of the analysis from that example (the content of the argument components was shortened or rephrased).\nThe annotation experiment was split into three phases. All documents were annotated by three independent annotators, who participated in two training sessions. During the first phase, 50 random comments and forum posts were annotated. Problematic cases were resolved after discussion and the guidelines were refined. In the second phase, we wanted to extend the range of annotated registers, so we selected 148 comments and forum posts as well as 41 blog posts. After the second phase, the annotation guidelines were final.\nIn the final phase, we extended the range of annotated registers and added newswire articles from the raw corpus in order to test whether the annotation guidelines (and inherently the model) is general enough. Therefore we selected 96 comments/forum posts, 8 blog posts, and 8 articles for this phase. A detailed inter-annotator agreement study on documents from this final phase will be reported in section UID75 .\nThe annotations were very time-consuming. In total, each annotator spent 35 hours by annotating in the course of five weeks. Discussions and consolidation of the gold data took another 6 hours. Comments and forum posts required on average of 4 minutes per document to annotate, while blog posts and articles on average of 14 minutes per document. Examples of annotated documents from the gold data are listed in Appendix UID158 .\nWe discarded 11 documents out of the total 351 annotated documents. Five forum posts, although annotated as persuasive in the first annotation study, were at a deeper look a mixture of two or more posts with missing quotations, therefore unsuitable for analyzing argumentation. Three blog posts and two articles were found not to be argumentative (the authors took no stance to the discussed controversy) and one article was an interview, which the current model cannot capture (a dialogical argumentation model would be required).\nFor each of the 340 documents, the gold standard annotations were obtained using the majority vote. If simple majority voting was not possible (different boundaries of the argument component together with a different component label), the gold standard was set after discussion among the annotators. We will refer to this corpus as the gold standard Toulmin corpus. The distribution of topics and registers in this corpus in shown in Table TABREF71 , and Table TABREF72 presents some lexical statistics.\nBased on pre-studies, we set the minimal unit for annotation as token. The documents were pre-segmented using the Stanford Core NLP sentence splitter BIBREF69 embedded in the DKPro Core framework BIBREF70 . Annotators were asked to stick to the sentence level by default and label entire pre-segmented sentences. They should switch to annotations on the token level only if (a) a particular sentence contained more than one argument component, or (b) if the automatic sentence segmentation was wrong. Given the “noise” in user-generated Web data (wrong or missing punctuation, casing, etc.), this was often the case.\nAnnotators were also asked to rephrase (summarize) each annotated argument component into a simple statement when applicable, as shown in Figure FIGREF66 . This was used as a first sanity checking step, as each argument component is expected to be a coherent discourse unit. For example, if a particular occurrence of a premise cannot be summarized/rephrased into one statement, this may require further splitting into two or more premises.\nFor the actual annotations, we developed a custom-made web-based application that allowed users to switch between different granularity of argument components (tokens or sentences), to annotate the same document in different argument “dimensions” (logos and pathos), and to write summary for each annotated argument component.\nAs a measure of annotation reliability, we rely on Krippendorff's unitized alpha ( INLINEFORM0 ) BIBREF71 . To the best of our knowledge, this is the only agreement measure that is applicable when both labels and boundaries of segments are to be annotated.\nAlthough the measure has been used in related annotation works BIBREF61 , BIBREF7 , BIBREF72 , there is one important detail that has not been properly communicated. The INLINEFORM0 is computed over a continuum of the smallest units, such as tokens. This continuum corresponds to a single document in the original Krippendorff's work. However, there are two possible extensions to multiple documents (a corpus), namely (a) to compute INLINEFORM1 for each document first and then report an average value, or (b) to concatenate all documents into one large continuum and compute INLINEFORM2 over it. The first approach with averaging yielded extremely high the standard deviation of INLINEFORM3 (i.e., avg. = 0.253; std. dev. = 0.886; median = 0.476 for the claim). This says that some documents are easy to annotate while others are harder, but interpretation of such averaged value has no evidence either in BIBREF71 or other papers based upon it. Thus we use the other methodology and treat the whole corpus as a single long continuum (which yields in the example of claim 0.541 INLINEFORM4 ).\nTable TABREF77 shows the inter-annotator agreement as measured on documents from the last annotation phase (see section UID67 ). The overall INLINEFORM0 for all register types, topics, and argument components is 0.48 in the logos dimension (annotated with the modified Toulmin's model). Such agreement can be considered as moderate by the measures proposed by Landis.Koch.1977, however, direct interpretation of the agreement value lacks consensus BIBREF54 . Similar inter-annotator agreement numbers were achieved in the relevant works in argumentation mining (refer to Table TABREF33 in section SECREF31 ; although most of the numbers are not directly comparable, as different inter-annotator metrics were used on different tasks).\nThere is a huge difference in INLINEFORM0 regarding the registers between comments + forums posts ( INLINEFORM1 0.60, Table TABREF77 a) and articles + blog posts ( INLINEFORM2 0.09, Table TABREF77 b) in the logos dimension. If we break down the value with respect to the individual argument components, the agreement on claim and premise is substantial in the case of comments and forum posts (0.59 and 0.69, respectively). By contrast, these argument components were annotated only with a fair agreement in articles and blog posts (0.22 and 0.24, respectively).\nAs can be also observed from Table TABREF77 , the annotation agreement in the logos dimension varies regarding the document topic. While it is substantial/moderate for prayer in schools (0.68) or private vs. public schools (0.44), for some topics it remains rather slight, such as in the case of redshirting (0.14) or mainstreaming (0.08).\nFirst, we examine the disagreement in annotations by posing the following research question: are there any measurable properties of the annotated documents that might systematically cause low inter-annotator agreement? We use Pearson's correlation coefficient between INLINEFORM0 on each document and the particular property under investigation. We investigated the following set of measures.\nFull sentence coverage ratio represents a ratio of argument component boundaries that are aligned to sentence boundaries. The value is 1.0 if all annotations in the particular document are aligned to sentences and 0.0 if no annotations match the sentence boundaries. Our hypothesis was that automatic segmentation to sentences was often incorrect, therefore annotators had to switch to the token level annotations and this might have increased disagreement on boundaries of the argument components.\nDocument length, paragraph length and average sentence length. Our hypotheses was that the length of documents, paragraphs, or sentences negatively affects the agreement.\nReadability measures. We tested four standard readability measures, namely Ari BIBREF73 , Coleman-Liau BIBREF74 , Flesch BIBREF75 , and Lix BIBREF76 to find out whether readability of the documents plays any role in annotation agreement.\nCorrelation results are listed in Table TABREF82 . We observed the following statistically significant ( INLINEFORM0 ) correlations. First, document length negatively correlates with agreement in comments. The longer the comment was the lower the agreement was. Second, average paragraph length negatively correlates with agreement in blog posts. The longer the paragraphs in blogs were, the lower agreement was reached. Third, all readability scores negatively correlate with agreement in the public vs. private school domain, meaning that the more complicated the text in terms of readability is, the lower agreement was reached. We observed no significant correlation in sentence coverage and average sentence length measures. We cannot draw any general conclusion from these results, but we can state that some registers and topics, given their properties, are more challenging to annotate than others.\nAnother qualitative analysis of disagreements between annotators was performed by constructing a probabilistic confusion matrix BIBREF77 on the token level. The biggest disagreements, as can be seen in Table TABREF85 , is caused by rebuttal and refutation confused with none (0.27 and 0.40, respectively). This is another sign that these two argument components were very hard to annotate. As shown in Table TABREF77 , the INLINEFORM5 was also low – 0.08 for rebuttal and 0.17 for refutation.\nWe analyzed the annotations and found the following phenomena that usually caused disagreements between annotators.\nEach argument component (e.g., premise or backing) should express one consistent and coherent piece of information, for example a single reason in case of the premise (see Section UID73 ). However, the decision whether a longer text should be kept as a single argument component or segmented into multiple components is subjective and highly text-specific.\nWhile rhetorical questions have been researched extensively in linguistics BIBREF78 , BIBREF79 , BIBREF80 , BIBREF81 , their role in argumentation represents a substantial research question BIBREF82 , BIBREF83 , BIBREF84 , BIBREF85 , BIBREF86 . Teninbaum.2011 provides a brief history of rhetorical questions in persuasion. In short, rhetorical questions should provoke the reader. From the perspective of our argumentation model, rhetorical questions might fall both into the logos dimension (and thus be labeled as, e.g., claim, premise, etc.) or into the pathos dimension (refer to Section SECREF20 ). Again, the decision is usually not clear-cut.\nAs introduced in section UID55 , rebuttal attacks the claim by presenting an opponent's view. In most cases, the rebuttal is again attacked by the author using refutation. From the pragmatic perspective, refutation thus supports the author's stance expressed by the claim. Therefore, it can be easily confused with premises, as the function of both is to provide support for the claim. Refutation thus only takes place if it is meant as a reaction to the rebuttal. It follows the discussed matter and contradicts it. Such a discourse is usually expressed as:\n[claim: My claim.] [rebuttal: On the other hand, some people claim XXX which makes my claim wrong.] [refutation: But this is not true, because of YYY.]\nHowever, the author might also take the following defensible approach to formulate the argument:\n[rebuttal: Some people claim XXX-1 which makes my claim wrong.] [refutation: But this is not true, because of YYY-1.] [rebuttal: Some people claim XXX-2 which makes my claim wrong.] [refutation: But this is not true, because of YYY-2.] [claim: Therefore my claim.]\nIf this argument is formulated without stating the rebuttals, it would be equivalent to the following:\n[premise: YYY-1.] [premise: YYY-2.] [claim: Therefore my claim.]\nThis example shows that rebuttal and refutation represent a rhetorical device to produce arguments, but the distinction between refutation and premise is context-dependent and on the functional level both premise and refutation have very similar role – to support the author's standpoint. Although introducing dialogical moves into monological model and its practical consequences, as described above, can be seen as a shortcoming of our model, this rhetoric figure has been identified by argumentation researchers as procatalepsis BIBREF43 . A broader view on incorporating opposing views (or lack thereof) is discussed under the term confirmation bias by BIBREF21 who claim that “[...] people are trying to convince others. They are typically looking for arguments and evidence to confirm their own claim, and ignoring negative arguments and evidence unless they anticipate having to rebut them.” The dialectical attack of possible counter-arguments may thus strengthen one's own argument.\nOne possible solution would be to refrain from capturing this phenomena completely and to simplify the model to claims and premises, for instance. However, the following example would then miss an important piece of information, as the last two clauses would be left un-annotated. At the same time, annotating the last clause as premise would be misleading, because it does not support the claim (in fact, it supports it only indirectly by attacking the rebuttal; this can be seen as a support is considered as an admissible extension of abstract argument graph by BIBREF87 ).\nDoc#422 (forumpost, homeschooling) [claim: I try not to be anti-homeschooling, but... it's just hard for me.] [premise: I really haven't met any homeschoolers who turned out quite right, including myself.] I apologize if what I'm saying offends any of you - that's not my intention, [rebuttal: I know that there are many homeschooled children who do just fine,] but [refutation: that hasn't been my experience.]\nTo the best of our knowledge, these context-dependent dialogical properties of argument components using Toulmin's model have not been solved in the literature on argumentation theory and we suggest that these observations should be taken into account in the future research in monological argumentation.\nAppeal to emotion, sarcasm, irony, or jokes are common in argumentation in user-generated Web content. We also observed documents in our data that were purely sarcastic (the pathos dimension), therefore logical analysis of the argument (the logos dimension) would make no sense. However, given the structure of such documents, some claims or premises might be also identified. Such an argument is a typical example of fallacious argumentation, which intentionally pretends to present a valid argument, but its persuasion is conveyed purely for example by appealing to emotions of the reader BIBREF88 .\nWe present some statistics of the annotated data that are important from the argumentation research perspective. Regardless of the register, 48% of claims are implicit. This means that the authors assume that their standpoint towards the discussed controversy can be inferred by the reader and give only reasons for that standpoint. Also, explicit claims are mainly written just once, only in 3% of the documents the claim was rephrased and occurred multiple times.\nIn 6% of the documents, the reasons for an implicit claim are given only in the pathos dimension, making the argument purely persuasive without logical argumentation.\nThe “myside bias”, defined as a bias against information supporting another side of an argument BIBREF89 , BIBREF90 , can be observed by the presence of rebuttals to the author's claim or by formulating arguments for both sides when the overall stance is neutral. While 85% of the documents do not consider any opposing side, only 8% documents present a rebuttal, which is then attacked by refutation in 4% of the documents. Multiple rebuttals and refutations were found in 3% of the documents. Only 4% of the documents were overall neutral and presented arguments for both sides, mainly in blog posts.\nWe were also interested whether mitigating linguistic devices are employed in the annotated arguments, namely in their main stance-taking components, the claims. Such devices typically include parenthetical verbs, syntactic constructions, token agreements, hedges, challenge questions, discourse markers, and tag questions, among others BIBREF91 . In particular, [p. 1]Kaltenbock.et.al.2010 define hedging as a discourse strategy that reduces the force or truth of an utterance and thus reduces the risk a speaker runs when uttering a strong or firm assertion or other speech act. We manually examined the use of hedging in the annotated claims.\nOur main observation is that hedging is used differently across topics. For instance, about 30-35% of claims in homeschooling and mainstreaming signal the lack of a full commitment to the expressed stance, in contrast to prayer in schools (15%) or public vs. private schools (about 10%). Typical hedging cues include speculations and modality (“If I have kids, I will probably homeschool them.”), statements as neutral observations (“It's not wrong to hold the opinion that in general it's better for kids to go to school than to be homeschooled.”), or weasel phrases BIBREF92 (“In some cases, inclusion can work fantastically well.”, “For the majority of the children in the school, mainstream would not have been a suitable placement.”).\nOn the other hand, most claims that are used for instance in the prayer in schools arguments are very direct, without trying to diminish its commitment to the conveyed belief (for example, “NO PRAYER IN SCHOOLS!... period.”, “Get it out of public schools”, “Pray at home.”, or “No organized prayers or services anywhere on public school board property - FOR ANYONE.”). Moreover, some claims are clearly offensive, persuading by direct imperative clauses towards the opponents/audience (“TAKE YOUR KIDS PRIVATE IF YOU CARE AS I DID”, “Run, don't walk, to the nearest private school.”) or even accuse the opponents for taking a certain stance (“You are a bad person if you send your children to private school.”).\nThese observations are consistent with the findings from the first annotation study on persuasion (see section UID48 ), namely that some topics attract heated argumentation where participant take very clear and reserved standpoints (such as prayer in schools or private vs. public schools), while discussions about other topics are rather milder. It has been shown that the choices a speaker makes to express a position are informed by their social and cultural background, as well as their ability to speak the language BIBREF93 , BIBREF94 , BIBREF91 . However, given the uncontrolled settings of the user-generated Web content, we cannot infer any similar conclusions in this respect.\nWe investigated premises across all topics in order to find the type of support used in the argument. We followed the approach of Park.Cardie.2014, who distinguished three types of propositions in their study, namely unverifiable, verifiable non-experiential, and verifiable experiential.\nVerifiable non-experiential and verifiable experiential propositions, unlike unverifiable propositions, contain an objective assertion, where objective means “expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations.” Such assertions have truth values that can be proved or disproved with objective evidence; the correctness of the assertion or the availability of the objective evidence does not matter BIBREF8 . A verifiable proposition can further be distinguished as experiential or not, depending on whether the proposition is about the writer's personal state or experience or something non-experiential. Verifiable experiential propositions are sometimes referred to as anectotal evidence, provide the novel knowledge that readers are seeking BIBREF8 .\nTable TABREF97 shows the distribution of the premise types with examples for each topic from the annotated corpus. As can be seen in the first row, arguments in prayer in schools contain majority (73%) of unverifiable premises. Closer examination reveals that their content vary from general vague propositions to obvious fallacies, such as a hasty generalization, straw men, or slippery slope. As Nieminen.Mustonen.2014 found out, fallacies are very common in argumentation about religion-related issues. On the other side of the spectrum, arguments about redshirting rely mostly on anecdotal evidence (61% of verifiable experiential propositions). We will discuss the phenomena of narratives in argumentation in more detail later in section UID98 . All the topics except private vs. public schools exhibit similar amount of verifiable non-experiential premises (9%–22%), usually referring to expert studies or facts. However, this type of premises has usually the lowest frequency.\nManually analyzing argumentative discourse and reconstructing (annotating) the underlying argument structure and its components is difficult. As [p. 267]Reed2006 point out, “the analysis of arguments is often hard, not only for students, but for experts too.” According to [p. 81]Harrell.2011b, argumentation is a skill and “even for simple arguments, untrained college students can identify the conclusion but without prompting are poor at both identifying the premises and how the premises support the conclusion.” [p. 81]Harrell.2011 further claims that “a wide literature supports the contention that the particular skills of understanding, evaluating, and producing arguments are generally poor in the population of people who have not had specific training and that specific training is what improves these skills.” Some studies, for example, show that students perform significantly better on reasoning tasks when they have learned to identify premises and conclusions BIBREF95 or have learned some standard argumentation norms BIBREF96 .\nOne particular extra challenge in analyzing argumentation in Web user-generated discourse is that the authors produce their texts probably without any existing argumentation theory or model in mind. We assume that argumentation or persuasion is inherent when users discuss controversial topics, but the true reasons why people participate in on-line communities and what drives their behavior is another research question BIBREF97 , BIBREF98 , BIBREF99 , BIBREF100 . When the analyzed texts have a clear intention to produce argumentative discourse, such as in argumentative essays BIBREF7 , the argumentation is much more explicit and a substantially higher inter-annotator agreement can be achieved.\nThe model seems to be suitable for short persuasive documents, such as comments and forum posts. Its applicability to longer documents, such as articles or blog posts, is problematic for several reasons.\nThe argument components of the (modified) Toulmin's model and their roles are not expressive enough to capture argumentation that not only conveys the logical structure (in terms of reasons put forward to support the claim), but also relies heavily on the rhetorical power. This involves various stylistic devices, pervading narratives, direct and indirect speech, or interviews. While in some cases the argument components are easily recognizable, the vast majority of the discourse in articles and blog posts does not correspond to any distinguishable argumentative function in the logos dimension. As the purpose of such discourse relates more to rhetoric than to argumentation, unambiguous analysis of such phenomena goes beyond capabilities of the current argumentation model. For a discussion about metaphors in Toulmin's model of argumentation see, e.g., BIBREF102 , BIBREF103 .\nArticles without a clear standpoint towards the discussed controversy cannot be easily annotated with the model either. Although the matter is viewed from both sides and there might be reasons presented for either of them, the overall persuasive intention is missing and fitting such data to the argumentation framework causes disagreements. One solution might be to break the document down to paragraphs and annotate each paragraph separately, examining argumentation on a different level of granularity.\nAs introduced in section SECREF20 , there are several dimensions of an argument. The Toulmin's model focuses solely on the logos dimension. We decided to ignore the ethos dimension, because dealing with the author's credibility remains unclear, given the variety of the source web data. However, exploiting the pathos dimension of an argument is prevalent in the web data, for example as an appeal to emotions. Therefore we experimented with annotating appeal to emotions as a separate category independent of components in the logos dimension. We defined some features for the annotators how to distinguish appeal to emotions. Figurative language such as hyperbole, sarcasm, or obvious exaggerating to “spice up” the argument are the typical signs of pathos. In an extreme case, the whole argument might be purely emotional, as in the following example.\nDoc#1698 (comment, prayer in schools) [app-to-emot: Prayer being removed from school is just the leading indicator of a nation that is ‘Falling Away’ from Jehovah. [...] And the disasters we see today are simply God’s finger writing on the wall: Mene, mene, Tekel, Upharsin; that is, God has weighed America in the balances, and we’ve been found wanting. No wonder 50 million babies have been aborted since 1973. [...]]\nWe kept annotations on the pathos dimension as simple as possible (with only one appeal to emotions label), but the resulting agreement was unsatisfying ( INLINEFORM0 0.30) even after several annotation iterations. Appeal to emotions is considered as a type of fallacy BIBREF104 , BIBREF18 . Given the results, we assume that more carefully designed approach to fallacy annotation should be applied. To the best of our knowledge, there have been very few research works on modeling fallacies similarly to arguments on the discourse level BIBREF105 . Therefore the question, in which detail and structure fallacies should be annotated, remains open. For the rest of the paper, we thus focus on the logos dimension solely.\nSome of the educational topics under examination relate to young children (e.g., redshirting or mainstreaming); therefore we assume that the majority of participants in discussions are their parents. We observed that many documents related to these topics contain narratives. Sometimes the story telling is meant as a support for the argument, but there are documents where the narrative has no intention to persuade and is simply a story sharing.\nThere is no widely accepted theory of the role of narratives among argumentation scholars. According to Fisher.1987, humans are storytellers by nature, and the “reason” in argumentation is therefore better understood in and through the narratives. He found that good reasons often take the form of narratives. Hoeken.Fikkers.2014 investigated how integration of explicit argumentative content into narratives influences issue-relevant thinking and concluded that identifying with the character being in favor of the issue yielded a more positive attitude toward the issue. In a recent research, Bex.2011 proposes an argumentative-narrative model of reasoning with evidence, further elaborated in BIBREF106 ; also Niehaus.et.al.2012 proposes a computational model of narrative persuasion.\nStemming from another research field, LeytonEscobar2014 found that online community members who use and share narratives have higher participation levels and that narratives are useful tools to build cohesive cultures and increase participation. Betsch.et.al.2010 examined influencing vaccine intentions among parents and found that narratives carry more weight than statistics.\nWe call the model a modified Toulmin model. It contains five argument components, namely, claim, premise, backing, rebuttal, and refutation.",

        "answer": "The authors consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nWe consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.",

        "answer": "A number of factors contributed to the United States defeating the Union of Soviet Socialist Republics (USSR) in the Cold War and becoming the world's most powerful state. A common view is that the U.S. won the Cold War because its capitalist economic system, characterized by free markets and the recognition of private property rights, was able to outperform the USSR's centrally-planned economy. The United States could therefore afford to spend more on its military than the USSR and won the nuclear arms race, which contributed to the internal collapse of the Soviet economy and the subsequent breakup of the Soviet Union into smaller, individual states with democratic elections. Additionally, though the USSR and the United States never officially engaged in direct military conflict with one another during the Cold War, various factions supported by the United States and its Western allies were able to successfully defeat Soviet-backed factions in proxy wars that took place all across the globe (with the notable exception of Vietnam). These defeats gradually limited the USSR's ability to project its power on the world stage, and helped the United States build and strengthen key alliances, including the North Atlantic Treaty Organization. Finally, the United States carried out effective intelligence, counter-intelligence, disinformation and propaganda campaigns that undermined the faith the USSR's population had in its government and buttressed support for the U.S. government's efforts domestically. By 1991, the Soviet Union had fallen and the U.S. had achieved global hegemony.",

        "answer": "Born and raised in Stevenage, Hertfordshire, Hamilton joined the McLaren young driver programme in 1998 at the age of 13, becoming the youngest racing driver ever to be contracted by a Formula One team. This led to a Formula One drive with McLaren for six years from 2007 to 2012, making Hamilton the first ever black driver to race in the series. In his inaugural season, Hamilton set numerous records as he finished runner-up to Kimi Räikkönen by one point. The following season, he won his maiden title in dramatic fashion—making a crucial overtake at the last corner on the last lap of the last race of the season—to become the then-youngest Formula One World Champion in history. After six years with McLaren, Hamilton signed with Mercedes in 2013.\n\nChanges to the regulations for 2014 mandating the use of turbo-hybrid engines saw the start of a highly successful period for Hamilton, during which he won six further drivers' titles. Consecutive titles came in 2014 and 2015 during an intense rivalry with teammate Nico Rosberg. Following Rosberg's retirement in 2016, Ferrari's Sebastian Vettel became Hamilton's closest rival in two championship battles, in which Hamilton twice overturned mid-season point deficits to claim consecutive titles again in 2017 and 2018. His third and fourth consecutive titles followed in 2019 and 2020 to equal Schumacher's record of seven drivers' titles. Hamilton achieved his 100th pole position and race win during the 2021 season.\n\nHamilton has been credited with furthering Formula One's global following by appealing to a broader audience outside the sport, in part due to his high-profile lifestyle, environmental and social activism, and exploits in music and fashion. He has also become a prominent advocate in support of activism to combat racism and push for increased diversity in motorsport. Hamilton was the highest-paid Formula One driver from 2013 to 2021, and was ranked as one of the world's highest-paid athletes by Forbes of twenty-tens decade and 2021. He was also listed in the 2020 issue of Time as one of the 100 most influential people globally, and was knighted in the 2021 New Year Honours.

        "evidence": "The task of interpreting and following natural language (NL) navigation instructions involves interleaving different signals, at the very least the linguistic utterance and the representation of the world. For example, in turn right on the first intersection, the instruction needs to be interpreted, and a specific object in the world (the intersection) needs to be located in order to execute the instruction. In NL navigation studies, the representation of the world may be provided via visual sensors BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4 or as a symbolic world representation. This work focuses on navigation based on a symbolic world representation (referred to as a map).\nPrevious datasets for NL navigation based on a symbolic world representation, HCRC BIBREF5, BIBREF6, BIBREF7 and SAIL BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15 present relatively simple worlds, with a small fixed set of entities known to the navigator in advance. Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes. Using Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers. This task raises several challenges. First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state.",

        "question": "Which countries has Tamil as one of their official languages?",
        "evidence": "Tamil (/ˈtɑːmɪl/; தமிழ் Tamiḻ [t̪amiɻ], pronunciation (help·info)) is a Dravidian language natively spoken by the Tamil people of South Asia. Tamil is an official language of the Indian state of Tamil Nadu, the sovereign nations of Sri Lanka and Singapore, and the Indian Union territory of Puducherry. Tamil is also spoken by significant minorities in the four other South Indian states of Kerala, Karnataka, Andhra Pradesh and Telangana, and the Union Territory of the Andaman and Nicobar Islands. It is also spoken by the Tamil diaspora found in many countries, including Malaysia, Myanmar, South Africa, United Kingdom, United States, Canada, Australia and Mauritius. Tamil is also natively spoken by Sri Lankan Moors. One of 22 scheduled languages in the Constitution of India, Tamil was the first to be classified as a classical language of India.\n\nTamil is one of the longest-surviving classical languages of India. A. K. Ramanujan described it as \"the only language of contemporary India which is recognizably continuous with a classical past\". The variety and quality of classical Tamil literature has led to it being described as \"one of the great classical traditions and literatures of the world\". Recorded Tamil literature has been documented for over 2000 years. The earliest period of Tamil literature, Sangam literature, is dated from c. 300 BC until AD 300. It has the oldest extant literature among Dravidian languages. The earliest epigraphic records found on rock edicts and 'hero stones' date from around the 3rd century BC. About 60,000 of the approximately 100,000 inscriptions found by the Archaeological Survey of India in India are in Tamil Nadu. Of them, most are in Tamil, with only about 5 percent in other languages. Tamil language inscriptions written in Brahmi script have been discovered in Sri Lanka and on trade goods in Thailand and Egypt. The two earliest manuscripts from India, acknowledged and registered by the UNESCO Memory of the World register in 1997 and 2005, were written in Tamil.\n\nIn 1578, Portuguese Christian missionaries published a Tamil prayer book in old Tamil script named Thambiran Vanakkam, thus making Tamil the first Indian language to be printed and published. The Tamil Lexicon, published by the University of Madras, was one of the earliest dictionaries published in Indian languages. According to a 2001 survey, there were 1,863 newspapers published in Tamil, of which 353 were dailies.\n\nClassification\nMain article: Dravidian languages\nTamil belongs to the southern branch of the Dravidian languages, a family of around 26 languages native to the Indian subcontinent.  It is also classified as being part of a Tamil language family that, alongside Tamil proper, includes the languages of about 35 ethno-linguistic groups such as the Irula and Yerukula languages (see SIL Ethnologue).\n\nThe closest major relative of Tamil is Malayalam; the two began diverging around the 9th century AD. Although many of the differences between Tamil and Malayalam demonstrate a pre-historic split of the western dialect, the process of separation into a distinct language, Malayalam, was not completed until sometime in the 13th or 14th century.\n\nHistory\n\nFindings from Adichanallur in the Government Museum, Chennai\n\nKeezhadi excavation site\nTamil, like other Dravidian languages, ultimately descends from the Proto-Dravidian language, which was most likely spoken around the third millennium BC, possibly in the region around the lower Godavari river basin. The material evidence suggests that the speakers of Proto-Dravidian were of the culture associated with the Neolithic complexes of South India.\n\nAmong Indian languages, Tamil has the most ancient non-Sanskritic Indian literature. Scholars categorise the attested history of the language into three periods: Old Tamil (600 BC–AD 700), Middle Tamil (700–1600) and Modern Tamil (1600–present). In November 2007, an excavation at Quseir-al-Qadim revealed Egyptian pottery dating back to first century BC with ancient Tamil Brahmi inscriptions. There are a number of apparent Tamil loanwords in Biblical Hebrew dating to before 500 BC, the oldest attestation of the language. John Guy states that Tamil was the lingua franca for early maritime traders from India.\n\nIn 2004, a number of skeletons were found buried in earthenware urns in Adichanallur. Some of these urns contained writing in Tamil Brahmi script, and some contained skeletons of Tamil origin.\n\nBetween 2017 and 2018, 5,820 artifacts have been found in Keezhadi. These sent to Beta Analytic in Miami, Florida for Accelerator Mass Spectrometry (AMS) dating. One sample containing Tamil-Brahmi inscriptions was claimed to be dated to around 580 BC.",

        "answer": "Yes.",
        "evidence": "Neural machine translation has attracted much attention in recent years BIBREF0, BIBREF1, BIBREF2, BIBREF3. Given a sentence $x=(x_1, \\dots ,x_{T_x})$ from the source language, the straight-forward way for translation is to generate the target words $y=(y_1, \\dots , y_{T_y})$ one by one from left to right. This is also known as the AutoRegressive Translation (ART) models, in which the joint probability is decomposed into a chain of conditional probabilities:\nWhile the ART models have achieved great success in terms of translation quality, the time consumption during inference is still far away from satisfactory. During training, the predictions at different positions can be estimated in parallel since the ground truth pair $(x,y)$ is exposed to the model. However, during inference, the model has to generate tokens sequentially as $y_{<t}$ must be inferred on the fly. Such autoregressive behavior becomes the bottleneck of the computational time BIBREF4.\nIn order to speed up the inference process, a line of works begin to develop non-autoregressive translation models. These models break the autoregressive dependency by decomposing the joint probability with\nThe lost of autoregressive dependency largely hurt the consistency of the output sentences, increase the difficulty in the learning process and thus lead to a low quality translation. Previous works mainly focus on adding different components into the NART model to improve the expressiveness of the network structure to overcome the loss of autoregressive dependency BIBREF5, BIBREF6, BIBREF7. However, the computational overhead of new components will hurt the inference speed, contradicting with the goal of the NART models: to parallelize and speed up neural machine translation models.\nTo tackle this, we proposed a novel hint-based method for NART model training. We first investigate the causes of the poor performance of the NART model. Comparing with the ART model, we find that: (1) the positions where the NART model outputs incoherent tokens will have very high hidden states similarity; (2) the attention distributions of the NART model are more ambiguous than those of ART model. Therefore, we design two kinds of hints from the hidden states and attention distributions of the ART model to help the training of the NART model. The experimental results show that our model achieves significant improvement over the NART baseline models and is even comparable to a strong ART baseline in BIBREF4.\nComparing with the ART model, we find that: (1) the positions where the NART model outputs incoherent tokens will have very high hidden states similarity; (2) the attention distributions of the NART model are more ambiguous than those of ART model.",

        "evidence": "While a full discussion of each ERP component and the features of language thought to trigger each are beyond the scope of this document (for reviews see e.g. BIBREF0 , BIBREF2 , BIBREF4 , BIBREF5 , and BIBREF6 ), we introduce some basic features of ERP components to help in the discussion later. ERP components are electrical potential responses measured with respect to a baseline that are triggered by an event (in our case the presentation of a new word to a participant in an experiment). The name of each ERP component reflects whether the potential is positive or negative relative to the baseline. The N400 is so-named because it is Negative relative to a baseline (the baseline is typically recorded just before a word is presented at an electrode that is not affected by the ERP response) and because it peaks in magnitude at about 400ms after a word is presented to a participant in an experiment. The P600 is Positive relative to a baseline and peaks around 600ms after a word is presented to a participant (though its overall duration is much longer and less specific in time than the N400). The post-N400 positivity is so-named because it is part of a biphasic response; it is a positivity that occurs after the negativity associated with the N400. The early post-N400 positivity (EPNP) is also part of a biphasic response, but the positivity has an eariler onset than the standard PNP. Finally, the LAN and ELAN are the left-anterior negativity and early left-anterior negativity respectively. These are named for their timing, spatial distribution on the scalp, and direction of difference from the baseline. It is important to note that ERP components can potentially cancel and mask each other, and that it is difficult to precisely localize the neural activity that causes the changes in electrical potential at the electrodes where those changes are measured.\nThe N400 is so-named because it is Negative relative to a baseline (the baseline is typically recorded just before a word is presented at an electrode that is not affected by the ERP response) and because it peaks in magnitude at about 400ms after a word is presented to a participant in an experiment.",

He then moved to Tennessee, where he established the town of LaFollette. His company, LaFollette Coal, Iron, and Railway Company, eventually employed more than 1500 people and was the largest blast furnace in the Southern United States.\n\nEarly life and education\nHarvey M. LaFollette was born in Primrose, Wisconsin. His first cousin, Robert Marion La Follette Sr., was three years old at the time and living on the adjoining farm. Harvey's father (also named Harvey M. LaFollette) was a farmer and served in local government both as sheriff and commissioner. When Harvey was two years old, his family relocated to join relatives in Thorntown, Indiana. Harvey's brother, William La Follette, was born shortly after they arrived in Indiana. When he was seven years old, his father was killed in an industrial accident while working on a piece of machinery in the flour mill he owned.\n\nYoung Harvey was always an avid reader, and after studying at the nearby Friends School and a short stint at Wabash College, he left for France, the land of his Huguenot ancestors, to continue his education. He studied in Paris at several institutions focusing on languages and civil engineering. He left Paris, travelling on foot and staying with peasant families to better understand the local dialects. He took additional courses in Germany and in Italy. He returned to Indiana in 1880 as a well-educated and travelled young man. He spoke five languages fluently.\n\nIndiana educator\nHe began teaching in the public schools as soon as he returned from abroad and became a school principal and a county superintendent before running for statewide office at the age of 28. He was elected to two terms as Indiana Superintendent of Public Instruction. In this job, he established a number of reforms as he standardized the textbooks and regularized the financial systems.\n\nLaFollette, Tennessee\nAlong with his youngest brother, Grant LaFollette, Harvey then moved some 400 miles (640 km) to the south and purchased more than 37,000 acres (150 km2) of land in the Tennessee mountains. He established and served as president and general manager of a company that eventually employed 1,500 people and became the largest blast furnace in the Southern United States. He built a railroad that allowed his product to be shipped. The town that grew up around his business venture was named LaFollette in his honor and became the county seat of Campbell County.\n\nPersonal life\n\nGlen Oaks\nHarvey built and lived in Glen Oaks, a 27–room mansion in the center of LaFollette designed by Knoxville architect George Franklin Barber. The home on Indiana Avenue is listed in the National Register of Historic Places. As his company grew, he traveled extensively and remained close to his extended family. During the glare of the Wisconsin governor's race of 1900, his mother and older brother and sister returned to Primrose with cousin Robert and other family members to visit the old log cabin where Harvey was born and to relive memories of the pioneering days of a half century earlier. During the next decade, Harvey and his wife were often in Washington, DC, visiting family members and meeting political allies. Vice President Charles W. Fairbanks was a friend from his younger days in Indiana. His brother and cousin both moved to the nation's capitol as members of Congress, and he visited them often. Later in his life, when the mines no longer produced and his business failed, he returned to his academic roots, corresponding with Abraham Lincoln scholar Louis A. Warren, who wrote The Lincoln and LaFollette Families in Pioneer Drama, a history of the Lincoln and LaFollette families on the Kentucky frontier in the years before Jesse LaFollette and Thomas Lincoln took their families across the Ohio River to settle in Indiana Territory.\n\nFamily\nHe was a member of the La Follette family. William La Follette was a younger brother. Robert M. La Follette Sr. was his first cousin. William Leroy LaFollette Jr. and Chester La Follette were nephews. Suzanne La Follette was a niece. Mimi LaFollette Summerskill was a grand niece. Her son was political leader Richard L. Wright. His only child, Warner Marion LaFollette, predeceased him. Harvey was visiting his brother, William, in Colfax, Washington when he died in 1929.

        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nThe memory network has two inputs: a piece of text, referred to as a story in QA systems, and a query.",

        "question": "For me it remains unclear why we need to both adapt large model to target data as well as train the compact model on source data + maintain a close distance to large model output over target. What would the performance be if I were to just train the compact model on a loss fn with source + KL-divergence (without having adapted the global model to target data first)? Or has this been done in previous work?",
        "answer": "Significant performance gain can be obtained by first adapting a large source model to a large target model and then transferring the knowledge of the large target model to the compact model, as explained below. The large source model has much larger model capacity than that of the compact model. Thus, after domain adaptation, the large target model can learn more fine-grained representations of the target data than the compact model. By transferring the knowledge of the large target model to the compact model via knowledge distillation (KD), the compact model can inherit those fine-grained representations of the target data. As a result, the compact model trained via the above procedure achieves much higher inference accuracy on the target data, as compared to the case where the compact model is directly trained over the target data. Training the compact model on source data is to prevent the compact model from forgetting the knowledge of the source data during the knowledge transfer process, and  the reason is explained in **A1**. If the compact model is trained via the approach mentioned in **Q2**, the compact model can only inherit the knowledge of the target data from the large source model. However, the large source model does not learn the fine-grained representations of the target data. As a result, the compact model can suffer low inference accuracy on the target data. Note that the approach mentioned in **Q2** has been adopted by MobileDA [1], and the experimental results in our paper show that our scheme outperforms MobileDA in terms of inference accuracy on the target data.\n",
        "evidence": "As shown in Table 8 and Table 9, TO-KD outperforms SHOT in terms of the inference accuracy on the target data. The gain comes from the large model capacity of large model.****The gain of our schemes can be explained as follows. The large target model used in STU-KD can learn more fine-grained representations of the target data than the compact model. Thus, the compact model that inherits the knowledge from the large target model can achieve higher inference accuracy on the target data, compared with the compact model that are directly trained using the target data.****According to Table 6 and Table 7, TO-KD and STU-KD (our schemes) outperforms other schemes in terms of the inference accuracy on the target data, and these two schemes achieve comparable inference accuracy on the target data.",

        "answer": "The first step is to select few sentences from the story and finally generate a summary from this extracted graph. The second step is to extract important information from the selected sentences by extracting a sub-graph from the selected sentences.",
        "evidence": "Summarization of large texts is still an open problem in language processing. People nowadays have lesser time and patience to go through large pieces of text which make automatic summarization important. Automatic summarization has significant applications in summarizing large texts like stories, journal papers, news articles and even larger texts like books.\nExisting methods for summarization can be broadly categorized into two categories Extractive and Abstractive. Extractive methods picks up words and sometimes directly sentences from the text. These methods are inherently limited in the sense that they can never generate human level summaries for large and complicated documents which require rephrasing sentences and incorporating information from full text to generate summaries. Most of the work done on summarization in past has been extractive.\nOn the other hand most Abstractive methods take advantages of the recent developments in deep learning. Specifically the recent success of the sequence to sequence learning models where recurrent networks read the text, encodes it and then generate target text. Though these methods have recently shown to be competitive with the extractive methods they are still far away from reaching human level quality in summary generation.\nThe work on summarization using AMR was started by BIBREF0 . Abstract Meaning Representation (AMR) was as introduced by BIBREF1 . AMR focuses on capturing the meaning of the text, by giving a specific meaning representation to the text. AMR tries to capture the \"who is doing what to whom\" in a sentence. The formalism aims to give same representation to sentences which have the same underlying meaning. For example \"He likes apple\" and \"Apples are liked by him\" should be assigned the same AMR.\n BIBREF0 's approach aimed to produce a summary for a story by extracting a summary subgraph from the story graph and finally generate a summary from this extracted graph. But, because of the unavailability of AMR to text generator at that time their work was limited till extracting the summary graph. This method extracts a single summary graph from the story graph. Extracting a single summary graph assumes that all of the important information from the graph can be extracted from a single subgraph. But, it can be difficult in cases where the information is spread out in the graph. Thus, the method compromises between size of the summary sub-graph and the amount of information it can extract. This can be easily solved if instead of a single sub-graph, we extract multiple subgraphs each focusing on information in a different part of the story.\nWe propose a two step process for extracting multiple summary graphs. First step is to select few sentences from the story. We use the idea that there are only few sentences that are important from the point of view of summary, i.e. most of the information contained in the summary is present in very few sentences and they can be used to generate the summary. Second step is to extract important information from the selected sentences by extracting a sub-graph from the selected sentences.\nOur main contributions in this work are three folds,\nThe rest of the paper is organized as follows. Section SECREF2 contains introduction to AMR, section SECREF3 and SECREF4 contains the datasets and the algorithm used for summary generation respectively. Section SECREF5 has a detailed step-by-step evaluation of the pipeline and in section SECREF6 we discuss the problems with the current dataset and evaluation metric.\nFirst step is to select few sentences from the story. We use the idea that there are only few sentences that are important from the point of view of summary, i.e. most of the information contained in the summary is present in very few sentences and they can be used to generate the summary.

        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier. When we combine the two models, we achieve state-of-the-art results over 3/4 of our datasets.\nThis paper makes the following contributions:\nAll code and data associated with this research will be released on publication.\n(i) this is the first study to use visual renderings of documents to capture implicit quality indicators not present in the document text, such as document visual layout; experimental results show that we can obtain a 2.9% higher accuracy using only visual renderings of documents compared with using only textual features over a Wikipedia dataset, and we can obtain competitive results over an arXiv dataset.

Although NMT can be significantly better than PBSMT in resource-rich scenarios, PBSMT performs better in low-resource scenarios BIBREF4 . Only by exploiting cross-lingual transfer learning techniques BIBREF5 , BIBREF6 , BIBREF7 , can the NMT performance approach PBSMT performance in low-resource scenarios.\nHowever, such methods usually require an NMT model trained on a resource-rich language pair like French INLINEFORM0 English (parent), which is to be fine-tuned for a low-resource language pair like Uzbek INLINEFORM1 English (child). On the other hand, multilingual approaches BIBREF8 propose to train a single model to translate multiple language pairs. However, these approaches are effective only when the parent target or source language is relatively resource-rich like English (En). Furthermore, the parents and children models should be trained on similar domains; otherwise, one has to take into account an additional problem of domain adaptation BIBREF9 .\nIn this paper, we work on a linguistically distant and thus challenging language pair Japanese INLINEFORM0 Russian (Ja INLINEFORM1 Ru) which has only 12k lines of news domain parallel corpus and hence is extremely resource-poor. Furthermore, the amount of indirect in-domain parallel corpora, i.e., Ja INLINEFORM2 En and Ru INLINEFORM3 En, are also small. As we demonstrate in Section SECREF4 , this severely limits the performance of prominent low-resource techniques, such as multilingual modeling, back-translation, and pivot-based PBSMT.

        "answer": "15 attributes.",
        "evidence": "In many organizations, PA is done from a predefined set of perspectives, which we call attributes. Each attribute covers one specific aspect of the work done by the employees. This has the advantage that we can easily compare the performance of any two employees (or groups of employees) along any given attribute. We can correlate various performance attributes and find dependencies among them. We can also cluster employees in the workforce using their supervisor ratings for each attribute to discover interesting insights into the workforce. The HR managers in the organization considered in this paper have defined 15 attributes (Table TABREF20 ). Each attribute is essentially a work item or work category described at an abstract level. For example, FUNCTIONAL_EXCELLENCE covers any tasks, goals or activities related to the software engineering life-cycle (e.g., requirements analysis, design, coding, testing etc.) as well as technologies such as databases, web services and GUI.\nIn the example in Section SECREF4 , the first sentence (which has class STRENGTH) can be mapped to two attributes: FUNCTIONAL_EXCELLENCE and BUILDING_EFFECTIVE_TEAMS. Similarly, the third sentence (which has class WEAKNESS) can be mapped to the attribute INTERPERSONAL_EFFECTIVENESS and so forth. Thus, in order to answer the second question in Section SECREF1 , we need to map each sentence in each of the 3 classes to zero, one, two or more attributes, which is a multi-class multi-label classification problem.\nWe manually tagged the same 2000 sentences in Dataset D1 with attributes, where each sentence may get 0, 1, 2, etc. up to 15 class labels (this is dataset D2). This labelled dataset contained 749, 206, 289, 207, 91, 223, 191, 144, 103, 80, 82, 42, 29, 15, 24 sentences having the class labels listed in Table TABREF20 in the same order. The number of sentences having 0, 1, 2, or more than 2 attributes are: 321, 1070, 470 and 139 respectively. We trained several multi-class multi-label classifiers on this dataset. Table TABREF21 shows the results of 5-fold cross-validation experiments on dataset D2.\nPrecision, Recall and F-measure for this multi-label classification are computed using a strategy similar to the one described in BIBREF21 . Let INLINEFORM0 be the set of predicted labels and INLINEFORM1 be the set of actual labels for the INLINEFORM2 instance. Precision and recall for this instance are computed as follows: INLINEFORM3 \nIt can be observed that INLINEFORM0 would be undefined if INLINEFORM1 is empty and similarly INLINEFORM2 would be undefined when INLINEFORM3 is empty. Hence, overall precision and recall are computed by averaging over all the instances except where they are undefined. Instance-level F-measure can not be computed for instances where either precision or recall are undefined. Therefore, overall F-measure is computed using the overall precision and recall.\nThe HR managers in the organization considered in this paper have defined 15 attributes (Table 6).

        "answer": "A better attention mechanism and semantic discourse information available in both the document as well as sentence-level contexts.",
        "evidence": "Named entity typing is the task of detecting the type (e.g., person, location, or organization) of a named entity in natural language text. Entity type information has shown to be useful in natural language tasks such as question answering BIBREF0 , knowledge-base population BIBREF1 , BIBREF2 , and co-reference resolution BIBREF3 . Motivated by its application to downstream tasks, recent work on entity typing has moved beyond standard coarse types towards finer-grained semantic types with richer ontologies BIBREF0 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . Rather than assuming an entity can be uniquely categorized into a single type, the task has been approached as a multi-label classification problem: e.g., in “... became a top seller ... Monopoly is played in 114 countries. ...” (fig:arch), “Monopoly” is considered both a game as well as a product.\nThe state-of-the-art approach BIBREF8 for fine-grained entity typing employs an attentive neural architecture to learn representations of the entity mention as well as its context. These representations are then combined with hand-crafted features (e.g., lexical and syntactic features), and fed into a linear classifier with a fixed threshold. While this approach outperforms previous approaches which only use sparse binary features BIBREF4 , BIBREF6 or distributed representations BIBREF9 , it has a few drawbacks: (1) the representations of left and right contexts are learnt independently, ignoring their mutual connection; (2) the attention on context is computed solely upon the context, considering no alignment to the entity; (3) document-level contexts which could be useful in classification are not exploited; and (4) hand-crafted features heavily rely on system or human annotations.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts. Further, we find that adaptive classification thresholds leads to further improvements. Experiments demonstrate that our approach, without any reliance on hand-crafted features, outperforms prior work on three benchmark datasets.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts.",

        "answer": "Identical hyperparameters: vector size of 300 components2, symmetric window of 2 words, negative sampling with 10 samples, 5 iterations over the corpus, no down-sampling.",
        "evidence": "As already stated, our main proposal is using neural embedding models to `project' documents in one language into the semantic space of another language. For this, we first trained a Continuous Bag-of-Words (CBOW) and a Continuous SkipGram model BIBREF0 for each of our monolingual subcorpora. The models were trained with identical hyperparameters: vector size of 300 components, symmetric window of 2 words, negative sampling with 10 samples, 5 iterations over the corpus, no down-sampling. The only language-dependent difference was that for the Ukrainian model we ignored words with the corpus frequency less than 10 and for the Russian model this threshold was set to 15 (as the Russian corpus is 3 times larger). All in all, the final Ukrainian model recognizes 429 215 words and the Russian one 271 720 words. Training was performed using CBOW and SkipGram implementation in Gensim library BIBREF7 .\nAfter the models were trained, we followed the path outlined in BIBREF4 to learn a linear transformation matrix from Ukrainian to Russian. First, we extracted all noun pairs from Russian-Ukrainian bilingual dictionary BIBREF8 , with the constraint that their frequency in our corpora was above the already mentioned thresholds 15 and 10 for Russian and Ukrainian words correspondingly. That made it a list of about 5 thousand pairs of nouns being translations of each other.\nFor all these words, their vectors were found in the models corresponding to the words' languages. It provided us with a matrix of 5 thousand of 300-dimensional Ukrainian vectors and the matrix of corresponding 5 thousand of 300-dimensional Russian vectors. This data served as a training set to learn an optimal transformation matrix. The latter is actually a 300x301 matrix of coefficients, such that when the initial Ukrainian matrix is multiplied by this transformation matrix, the result is maximally close to the corresponding Russian matrix. This transformation matrix has 301 (not 300) columns, because we add one component equal to 1 to each vector, as a bias term.\nProducing the transformation matrix is a linear regression problem: the input is 301 components of Ukrainian vectors (including the bias term) and the output is 300 components of Russian vectors. As we need 300 values as an output, there are actually 300 linear regression problems and that's why the resulting matrix size is 300x301 (301 weights for each of 300 components).\nThere are two main ways to solve a linear regression problem: one can either learn the optimal weights in an iterative way using some variant of gradient descent, or one can solve it numerically without iteration, using normal equation. For English and Spanish, BIBREF4 used stochastic gradient descent. However, normal equation is actually less error-prone and is guaranteed to find the global optimum. Its only disadvantage is that it becomes very computationally expensive when the number of features is large (thousands and more). However, in our case the number of features is only 301, so computational complexity is not an issue.\nThus, we use normal equation to find the optimal transformation matrix. The algebraic solution to each of 300 normal equations (one for each vector component $i$ ) is shown in the Equation 3 : \n$$\\beta _i = (\\textbf {X}^\\intercal * \\textbf {X})^{-1} * \\textbf {X}^\\intercal * y_i$$   (Eq. 3) \nwhere $\\textbf {X}$ is the matrix of 5 thousand Ukrainian word vectors (input), $y_i$ is the vector of the $i$ th components of 5 thousand corresponding Russian words (correct predictions), and $\\beta _i$ is our aim: the vector of 301 optimal coefficients which transform the Ukrainian vectors into the $i$ th component of the Russian vectors.\nAfter solving such normal equations for all the 300 components $i$ , we have the 300x301 linear transformation matrix which fits the data best.\nThis matrix basically maps the Ukrainian vectors into the Russian ones. It is based on the assumption that the relations between semantic concepts in different languages are in fact very similar (students are close to teachers, while pirates are close to corsairs, and so on). In continuous distributional models which strive to represent these semantic spaces, mutual `geometrical' relations between vectors representing particular words are also similar across models (if they are trained on comparable corpora), but the exact vectors for words denoting one and the same notion are different. This is because the models themselves are stochastic and the particular values of vectors (unlike their positions in relation to each other) depend a lot on technical factors, including the random seed used to initialize vectors prior to training. In order to migrate from a model A to another model B, one has to `rotate and scale' A vectors in a uniform linear way. To learn the optimal transformation matrix means to find out the exact directions of rotating and scaling, which minimize prediction errors.\nLinguistically speaking, once we learned the transformation matrix, we can predict what a Russian vector would most probably be, given a Ukrainian one. This essentially means we are able to `translate' Ukrainian words into Russian, by calculating the word in the Russian model with the vector closest to the predicted one.\nWe had to choose between CBOW or Continuous SkipGram models to use when learning the transformation matrix. Also, there was a question of whether to employ regularized or standard normal equations. Regularization is an attempt to avoid over-fitting by trying to somehow decrease the values of learned weights. The regularized normal equation is shown in 4 : \n$$\\beta _i = (\\textbf {X}^\\intercal * \\textbf {X} + \\lambda * L)^{-1} * \\textbf {X}^\\intercal * y_i$$   (Eq. 4) \nComparing to 3 , it adds the term $\\lambda * L$ , where $L$ is the identity matrix of the size equal to the number of features, with 0 at the top left cell, and $\\lambda $ is a real number used to tune the influence of regularization term (if $\\lambda = 0$ , there is no regularization).\nTo test all the possible combinations of parameters, we divided the bilingual dictionary into 4500 noun pairs used as a training set and 500 noun pairs used as a test set. We then learned transformation matrices on the training set using both training algorithms (CBOW and SkipGram) and several values of regularization $\\lambda $ from 0 to 5, with a step of 0.5. The resulting matrices were applied to the Ukrainian vectors from the test set and the corresponding Russian `translations' were calculated. The ratio of correct `translations' (matches) was used as an evaluation measure. It came out that regularization only worsened the results for both algorithms, so in the Table 1 we report the results without regularization.\nFor reference, we also report the accuracy of `quazi-translation' via Damerau-Levenshtein edit distance BIBREF9 , as a sort of a baseline. As already stated, the two languages share many cognates, and a lot of Ukrainian words can be orthographically transformed into their Russian translations (and vice versa) by one or two character replacements. Thus, we extracted 50,000 most frequent nouns from our Russian corpora; then for each Ukrainian noun in the bilingual dictionary we found the closest Russian noun (or 5 closest nouns for @5 metric) by edit distance and calculated how often it turned out to be the correct translation. As the Table 1 shows, notwithstanding the orthographic similarity of the two languages, CBOW consistently outperforms this approach even on the test set. On the training set, its superiority is even more obvious.\nAs already stated, our main proposal is using neural embedding models to ‘project’documents in one language into the semantic space of another language. For this, we first trained a Continuous Bag-of-Words (CBOW) and a Contin uous SkipGram model (Mikolov et al., 2013b) for each of our monolingual subcorpora. The models were trained with identical hyperparameters: vector size of 300 components2, symmetric window of 2 words, negative sampling with 10 samples, 5 iterations over the corpus, no down-sampling.",

White of the Sherwood Conservatory of Music Columbia College Chicago and Karel Paukert at Northwestern University. His theatre organ teacher was Al Melgard, famous as the Staff Organist on the Barton organ at the Chicago Stadium. When Melgard retired in 1975 he gave Strony his Oak Park, IL teaching studio. Strony later studied piano with Giulio Favrio of the Lyric Opera of Chicago.\n\nHe made his public debut as an organist in 1974, aged 18. During his college years he began playing the theatre organ in pizza parlors, a fad in the 1970s which gave new life to a largely forgotten instrument. For many years thereafter he was Artist-in-Residence at First Christian Church in Las Vegas, Nevada.\n\nStrony has studied with silent-film accompanists and has accompanied silent films for years, such as The Phantom of the Opera (1925 film) and Nosferatu at the Plaza Theatre (El Paso).\n\nPerformances\nHe has performed in the United States, toured extensively in Australia (1978), England (1989), Japan (Expo ‘75 & 2011), and Canada (1999), and he is a regular performer at conventions of the American Theatre Organ Society. In 2012 he played his 39th ATOS convention, more than any other organist. He played there again in 2008. He has also performed for the American Guild of Organists on both local and national levels.\n\nHe has performed on numerous classical instruments as well, most notably having been featured in June 2009 at Macy's in Philadelphia (formerly Wanamaker’s) playing the largest operating pipe organ in the world. He has also recorded on the world’s largest theatre organ at the Sanfillipo Music Room in Barrington, IL.\n\nIn addition to solo concerts, he has performed with several symphony orchestras. In El Paso he played music including Symphony No. 3 (Organ) of Camille Saint-Saëns. He played at the Calgary International Organ Festival with the Calgary Philharmonic. Additionally, he has performed with the Allentown Symphony and Symphony Silicon Valley. While in college he performed the Poulenc Organ Concerto with the Chicago Businessman’s Orchestra.\n\nAwards\nIn 1991 and 1993 the American Theatre Organ Society selected him as \"Organist of the Year.\" He is the only living organist to have received this award twice. In 2011 he was inducted into the American Theatre Organ Society Hall of Fame.\n\nIn the spring of 2008, and in celebration of his career, the Allen Organ Company developed the Walt Strony Signature Model - the STR-4 - which is a four-manual instrument. Strony designed the stoplist and chose all the samples from their extensive library based upon his experience as an organist and tonal consultant.\n\nOther work\nHis book The Secrets of Theatre Organ Registration (1991) was the first book to be written about this subject. According to the New York Times, this is \"what many theater organists consider the definitive guide\" to Wurlitzers.

        "evidence": "Curriculum Plausibility ::: Conversational Attributes ::: Specificity\nA notorious problem for neural dialogue generation model is that the model is prone to generate generic responses. The most unspecific responses are easy to learn, but are short and meaningless, while the most specific responses, consisting of too many rare words, are too difficult to learn, especially at the initial learning stage. Following BIBREF11, we measure the specificity of the response in terms of each word $w$ using Normalized Inverse Document Frequency (NIDF, ranging from 0 to 1):\nCurriculum Plausibility ::: Conversational Attributes ::: Repetitiveness\nRepetitive responses are easy to generate in current auto-regressive response decoding, where response generation loops frequently, whereas diverse and informative responses are much more complicated for neural dialogue generation. We measure the repetitiveness of a response $r$ as:\nCurriculum Plausibility ::: Conversational Attributes ::: Continuity\nA coherent response not only responds to the given query, but also triggers the next utterance. An interactive conversation is carried out for multiple rounds and a response in the current turn also acts as the query in the next turn. As such, we introduce the continuity metric, which is similar to the query-relatedness metric, to assess the continuity of a response $r$ with respect to the subsequent utterance $u$, by measuring the cosine similarities between them.\nCurriculum Plausibility ::: Conversational Attributes ::: Model Confidence\nDespite the heuristic dialogue attributes, we further introduce the model confidence as an attribute, which distinguishes the easy-learnt samples from the under-learnt samples in terms of the model learning ability. A pretrained neural dialogue generation model assigns a relatively higher confidence probability for the easy-learnt samples than the under-learnt samples. Inspired by BIBREF16, BIBREF17, we employ the negative loss value of a dialogue sample under the pretrained model as the model confidence measure, indicating whether a sampled response is easy to be generated. Here we choose the attention-based sequence-to-sequence architecture with a cross-entropy objective as the underlying dialogue model.\nCurriculum Plausibility ::: Conversational Attributes ::: Query-relatedness\nA conversation is considered to be coherent if the response correlates well with the given query. For example, given a query “I like to paint”, the response “What kind of things do you paint?” is more relevant and easier to learn than another loosely-coupled response “Do you have any pets?”. Following previous work BIBREF14, we measure the query-relatedness using the cosine similarities between the query and its corresponding response in the embedding space: $\\textit {cos\\_sim}(\\textit {sent\\_emb}(c), \\textit {sent\\_emb}(r))$, where $c$ is the query and $r$ is the response. The sentence embedding is computed by taking the average word embedding weighted by the smooth inverse frequency $\\textit {sent\\_emb}(e)=\\frac{1}{|e|}\\sum _{w\\in {}e}\\frac{0.001}{0.001 + p(w)}emb(w)$ of words BIBREF15, where $emb(w)$ and $p(w)$ are the embedding and the probability of word $w$ respectively.\nCurriculum Plausibility ::: Conversational Attributes ::: Specificity\nA notorious problem for neural dialogue generation model is that the model is prone to generate generic responses.\nCurriculum Plausibility ::: Conversational Attributes ::: Repetitiveness\nRepetitive responses are easy to generate in current auto-regressive response decoding, where response generation loops frequently, whereas diverse and informative responses are much more complicated for neural dialogue generation.\nCurriculum Plausibility ::: Conversational Attributes ::: Continuity\nA coherent response not only responds to the given query, but also triggers the next utterance.\nCurriculum Plausibility ::: Conversational Attributes ::: Model Confidence\nDespite the heuristic dialogue attributes, we further introduce the model confidence as an attribute, which distinguishes the easy-learnt samples from the under-learnt samples in terms of the model learning ability.\nCurriculum Plausibility ::: Conversational Attributes ::: Query-relatedness\nA conversation is considered to be coherent if the response correlates well with the given query.",

        "question": "What does the number of reasoning steps it takes depend on?",
        "answer": "The complexity of the input question and passage.",
        "evidence": "The goal of Machine Reading Comprehension (MRC) is to have machines read a text passage and then generate an answer (or select an answer from a list of given candidates) for any question about the passage. There has been a growing interest in the research community in exploring neural MRC models in an end-to-end fashion, thanks to the availability of large-scale datasets, such as CNN/DM BIBREF0 and SQuAD BIBREF1 .\nDespite the variation in model structures, most state-of-the-art models perform reading comprehension in two stages. First, the symbolic representations of passages and questions are mapped into vectors in a neural space. This is commonly achieved via embedding and attention BIBREF2 , BIBREF3 or fusion BIBREF4 . Then, reasoning is performed on the vectors to generate the right answer.\nIdeally, the best attention and reasoning strategies should adapt organically in order to answer different questions. However, most MRC models use a static attention and reasoning strategy indiscriminately, regardless of various question types. One hypothesis is because these models are optimized on those datasets whose passages and questions are domain-specific (or of a single type). For example, in CNN/DM, all the passages are news articles, and the answer to each question is an entity in the passage. In SQuAD, the passages came from Wikipedia articles and the answer to each question is a text span in the article. Such a fixed-strategy MRC model does not adapt well to other datasets. For example, the exact-match score of BiDAF BIBREF2 , one of the best models on SQuAD, drops from 81.5 to 55.8 when applied to TriviaQA BIBREF5 , whereas human performance is 82.3 and 79.7 on SQuAD and TriviaQA, respectively.\nIn real-world MRC tasks, we must deal with questions and passages of different types and complexities, which calls for models that can dynamically determine what attention and reasoning strategy to use for any input question-passage pair on the fly. In a recent paper, BIBREF6 proposed dynamic multi-step reasoning, where the number of reasoning steps is determined spontaneously (using reinforcement learning) based on the complexity of the input question and passage. With a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.\nThe proposed model is called a Dynamic Fusion Network (DFN). In this paper, we describe the version of DFN developed on the RACE dataset BIBREF7 . In RACE, a list of candidate answers is provided for each passage-question pair. So DFN for RACE is a scoring model - the answer candidate with the highest score will be selected as the final answer.\nLike other MRC models, DFNs also perform machine reading in two stages: attention and reasoning. DFN is unique in its use of a dynamic multi-strategy attention process in the attention stage. Here “attention” refers to the process that texts from different sources (passage, question, answers) are combined in the network. In literature, a fixed attention mechanism is usually employed in MRC models. In DFN, the attention strategy is not static; instead, the actual strategy for drawing attention among the three text sources are chosen on the fly for each sample. This lends flexibility to adapt to various question types that require different comprehension skills. The output of the attention stage is then fed into the reasoning module to generate the answer score. The reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.\nInspired by ReasoNet BIBREF6 and dynamic neural module networks BIBREF8 , we use deep reinforcement learning methods BIBREF9 , BIBREF10 to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample. We use RL in favor of other simpler methods (like cascading, pooling or weighted averaging) mainly because we intend to learn a policy that constructs an instance of DFN of a sample-specific structure. Given an input sample consisting of a question, a passage and a list of candidate answers in RACE, an instance of DFN can be constructed via RL step by step on the fly. Such a policy is particularly appealing as it also provides insights on how the model performs on different types of questions. At each decision step, the policy maps its “state”, which represents an input sample, and DFN's partial knowledge of the right answer, to the action of assembling proper attention and reasoning modules for DFN.\nExperiments conducted on the RACE dataset show that DFN significantly outperforms previous state-of-the-art MRC models and has achieved the best result reported on RACE. A thorough empirical analysis also demonstrates that DFN is highly effective in understanding passages of a wide variety of styles and answering questions of different complexities.\nThe reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.",

Since authors of these works did not cite each other, it is possible that that these features might have been identified independently. This, in turn, supports the hypothesis that if adequate details of any one or two of these applications are fed to a system described in this work, which is designed to estimate semantic similarities across applications, system can automatically suggest potential features for consideration for the remaining applications to start with without requiring manual knowledge of the semantically related applications.\nObjective of this study is to design a ML model for identifying if there exist mentions of one of the nine types of bio-molecular interactions in (publicly available) Biomedical data.",

        "evidence": "Montessori classrooms for children from 2+1⁄2 or 3 to 6 years old are often called Children's Houses, after Montessori's first school, the Casa dei Bambini in Rome in 1906. A typical classroom serves 20 to 30 children in mixed-age groups, staffed by a fully trained lead teacher and assistants. Classrooms are usually outfitted with child-sized tables and chairs arranged singly or in small clusters, with classroom materials on child-height shelves throughout the room. Activities are for the most part initially presented by the teacher, after which they may be chosen more or less freely by the children as interest dictates. A teacher's role within a Montessori classroom is to guide and consult students individually by letting each child create their own learning pathway. Classroom materials usually include activities for engaging in practical skills such as pouring and spooning, washing up, scrubbing tables and sweeping. Also materials for the development of the senses, mathematical materials, language materials, music, art and cultural materials, including more science-based activities like 'sink and float', Magnetic and Non magnetic and candle and air.\n\nActivities in Children's Houses are typically hands-on, tactile materials to teach concepts. For example, to teach writing, students use sandpaper letters. These are letters created by cutting letters out of sandpaper and placing them on wooden blocks. The children then trace these letters with their fingers to learn the shape and sound of each letter. Another example is the use of bead chains to teach math concepts, specifically multiplication. Specifically for multiples of 10, there is one bead that represents one unit, a bar of ten beads put together that represents 1×10, then a flat shape created by fitting 10 of the bars together to represent 10×10, and a cube created by fitting 10 of the flats together to represent 10×10×10.

Its rival Pepsi had no such qualms, and after the long-term success of its sugar-free Diet Pepsi (launched in 1964) became clear, Coca-Cola decided to launch a competing sugar-free brand under the Coca-Cola name that could be marketed more easily than Tab. Diet Coke was launched in 1982 and quickly overtook Tab in sales by a wide margin, though the older drink would remain on the market for decades until the COVID-19 pandemic forced Coca-Cola to discontinue Tab along with other slower-selling drinks in 2020.\n\nDiet Coke is not based on the Coca-Cola formula, but instead on Tab. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high-fructose corn syrup and had a slightly different balance of ingredients. In 2005, the company introduced Coca-Cola Zero (renamed Coca-Cola Zero Sugar in 2017), a sugar-free formula more closely based on original Coca-Cola.\n\nIn 2005, under pressure from retailer Walmart (which was impressed with the over-the-counter popularity of Splenda sweetener), the company released a new formulation called \"Diet Coke sweetened with Splenda\". Sucralose and acesulfame potassium replaced aspartame in this version. As the formulation was done to mollify one retailer, this variety had little advertising and promotion, as the company preferred to market Coca-Cola Zero instead. By late 2009, most distributors had stopped distributing the Splenda-formulated Diet Coke.\n\nIn 2018, in an effort to be more appealing to millennials, Diet Coke was packaged in a taller, more slender can (of the same volume) and introduced four new flavors.

        "evidence": "Major progress has been made in different tasks in Natural Language Processing, yet our models are still not able to describe why they make their decisions when summarizing an article, translating a sentence, or answering a question. Lack of meta information (e.g. general world knowledge regarding the task) is one important obstacle in the construction of language understanding models capable of reasoning about their considerations when making decisions (predictions).\nWikipedia is a great resource of world knowledge for human beings, but lacks the proper structure to be useful for the models. To address this issue and make a more structured knowledge-base, we are trying to structure Wikipedia. The final goal is to have, for each Wikipedia article, known entities and sets of attributes, with each attribute linking to other entities wherever possible. The initial step towards this goal is to classify the entities into predefined categories and verify the results using human annotators.\nThroughout the past years, many have tried classifying Wikipedia articles into different category sets the majority of which range between 3 to 15 class types BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4. Although useful, such categorization type sets are not much helpful when the classified articles are being used as the training data for Question-Answering systems, since the extracted knowledge-base does not provide detailed enough information to the model.\nOn the other hand, much larger categorization type sets such as Cyc-Taxonomy BIBREF5, Yago-Taxonomy BIBREF6, or Wikipedia's own taxonomy of categories BIBREF7 are not suitable for our task since the tags are not verifiable for annotators. In addition, taxonomies are not designed in a tree format, so some categories might have multiple super-categories and this would make the verification process much harder for the cases that the article is about multiple different topics.\nConsidering the mentioned problem requirements, we believe Extended Named Entities Hierarchy BIBREF8, containing 200 fine-grained categories tailored for Wikipedia articles, is the best fitting tag set.\nHigashinaka et al. higashinaka2012 were the first to use this extended tag set as the categorization output of the dumped Wikipedia pages while using a hand-extracted feature set for converting the pages into their model input vectors. Following their work, Suzuki et al. suzuki2016 modelled the links between different Wikipedia pages as an augmentation to the extracted input features to the classifier. They also proposed a more complex model for learning the mapping between the converted articles and the labels.\nAlthough providing useful insights, none of the works above have considered the multi-lingual nature of many Wikipedia articles. Hence, we decided to hire annotators and educate them on the Extended Named Entities (ENE) tag set to annotate each article with up to 6 different ENE classes, and exploit the Wikipedia language links in the annotated articles to create our multi-lingual Wikipedia classification dataset. Section 2 details our dataset creation process.\nWe then used the two models mentioned above, which are to the best of our knowledge the only works close enough to our task in hand, to benchmark our dataset. Section 3 provides more details about our feature selection method and the models. Section 4 presents our experimental setup and the classification results.\nHence, we decided to hire annotators and educate them on the Extended Named Entities (ENE) tag set to annotate each article with up to 6 different ENE classes, and exploit the Wikipedia language links in the annotated articles to create our multi-lingual Wikipedia classification dataset.",

        "answer": "(1) words (2) characters and character sequences and (3) gold morphological analysis.",
        "evidence": "Encoding of words is perhaps the most important step towards a successful end-to-end natural language processing application. Although word embeddings have been shown to provide benefit to such models, they commonly treat words as the smallest meaning bearing unit and assume that each word type has its own vector representation. This assumption has two major shortcomings especially for languages with rich morphology: (1) inability to handle unseen or out-of-vocabulary (OOV) word-forms (2) inability to exploit the regularities among word parts. The limitations of word embeddings are particularly pronounced in sentence-level semantic tasks, especially in languages where word parts play a crucial role. Consider the Turkish sentences “Köy+lü-ler (villagers) şehr+e (to town) geldi (came)” and “Sendika+lı-lar (union members) meclis+e (to council) geldi (came)”. Here the stems köy (village) and sendika (union) function similarly in semantic terms with respect to the verb come (as the origin of the agents of the verb), where şehir (town) and meclis (council) both function as the end point. These semantic similarities are determined by the common word parts shown in bold. However ortographic similarity does not always correspond to semantic similarity. For instance the ortographically similar words knight and night have large semantic differences. Therefore, for a successful semantic application, the model should be able to capture both the regularities, i.e, morphological tags and the irregularities, i.e, lemmas of the word.\nMorphological analysis already provides the aforementioned information about the words. However access to useful morphological features may be problematic due to software licensing issues, lack of robust morphological analyzers and high ambiguity among analyses. Character-level models (CLM), being a cheaper and accessible alternative to morphology, have been reported as performing competitively on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 . However the extent to which these tasks depend on morphology is small; and their relation to semantics is weak. Hence, little is known on their true ability to reveal the underlying morphological structure of a word and their semantic capabilities. Furthermore, their behaviour across languages from different families; and their limitations and strengths such as handling of long-range dependencies, reaction to model complexity or performance on out-of-domain data are unknown. Analyzing such issues is a key to fully understanding the character-level models.\nTo achieve this, we perform a case study on semantic role labeling (SRL), a sentence-level semantic analysis task that aims to identify predicate-argument structures and assign meaningful labels to them as follows:\n $[$ Villagers $]$ comers came $[$ to town $]$ end point\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis. The gold morphology serves as the upper bound for us to compare and analyze the performances of character-level models on languages of varying morphological typologies. We carry out an exhaustive error analysis for each language type and analyze the strengths and limitations of character-level models compared to morphology. In regard to the diversity hypothesis which states that diversity of systems in ensembles lead to further improvement, we combine character and morphology-level models and measure the performance of the ensemble to better understand how similar they are.\nWe experiment with several languages with varying degrees of morphological richness and typology: Turkish, Finnish, Czech, German, Spanish, Catalan and English. Our experiments and analysis reveal insights such as:\nWe use a simple method based on bidirectional LSTMs to train three types of base semantic role labelers that employ (1) words (2) characters and character sequences and (3) gold morphological analysis.",

        "evidence": "The citric acid cycle (CAC)—also known as the Krebs cycle, Szent-Györgyi-Krebs cycle or the TCA cycle (tricarboxylic acid cycle)—is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. The Krebs cycle is used by organisms that respire (as opposed to organisms that ferment) to generate energy, either by anaerobic respiration or aerobic respiration. In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, that are used in numerous other reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest components of metabolism and may have originated abiogenically. Even though it is branded as a 'cycle', it is not necessary for metabolites to follow only one specific route; at least three alternative segments of the citric acid cycle have been recognized.\n\nThe name of this metabolic pathway is derived from the citric acid (a tricarboxylic acid, often called citrate, as the ionized form predominates at biological pH) that is consumed and then regenerated by this sequence of reactions to complete the cycle. The cycle consumes acetate (in the form of acetyl-CoA) and water, reduces NAD+ to NADH, releasing carbon dioxide. The NADH generated by the citric acid cycle is fed into the oxidative phosphorylation (electron transport) pathway. The net result of these two closely linked pathways is the oxidation of nutrients to produce usable chemical energy in the form of ATP.\n\nIn eukaryotic cells, the citric acid cycle occurs in the matrix of the mitochondrion. In prokaryotic cells, such as bacteria, which lack mitochondria, the citric acid cycle reaction sequence is performed in the cytosol with the proton gradient for ATP production being across the cell's surface (plasma membrane) rather than the inner membrane of the mitochondrion.\n\nFor each pyruvate molecule (from glycolysis), the overall yield of energy-containing compounds from the citric acid cycle is three NADH, one FADH2, and one GTP.",

        "question": "Did they build the linguistic and the temporal models using the same framework?",
        "answer": "Yes.",
        "evidence": "Finally, we created a combined temporal-linguistic model. Since both the linguistic and the temporal models were built using the same framework, it was fairly simple to combine the two models. The combined model was created by merging the linguistic and temporal corpora and vocabularies. (Recall that we treated temporal features as words). We then experimented with the same four methods as in the last two sections to create our combined models.\nTable 4 shows the performance of each of these models. Across the board, the combined models outperformed their corresponding linguistic and temporal models, though the difference with the linguistic models were not as great. These results suggest that at some level the temporal and the linguistic \"styles\" of users provide non-overlapping cues about the identity of said users. Also, note that as with the linguistic and temporal models, our combined confusion model outperformed the other combined models.\nAnother way to evaluate the performance of the different combined models is through the rank-statistics plot. This is shown in Figure 2 . The figure shows the distribution of the ranks of the $5,612$ users for different combined models. The x-axis is the rank percentile (divided into bins of $5\\%$ ), the y-axis is the percentage of the users that fall in each bin. For example, for the confusion model, $69\\%$ (3880) of the $5,612$ users were correctly linked between Twitter and Facebook when looking at the top $5\\%$ (281) of the predictions by the model. From the figure, you can clearly see that the confusion model is superior to the other models, with TF-IDF a close second. You can also see from the figure that the rank plot for the random baseline is a horizontal line, with each rank percentile bin having $5\\%$ of the users ( $5\\%$ because the rank percentiles were divided into bins of $5\\%$ ).\nSince both the linguistic and the temporal models were built using the same framework, it was fairly simple to combine the two models.",

        "question": "Why is the BaB attack speed a little bit slow?",
        "answer": "We do agree our attack is relatively slow because we conduct a systematic search on activation space. It should be used as a last resort after existing fast attack algorithms searching directly in input space (e.g., PGD) fail. In Table 2, we show that we can attack more images and discover adversarial examples where all existing adversarial attacks fail. Also, compared to some other strong attacks such as FAB and Square attacks, our time is similar to theirs (see new results in Table 2). Additionally, we are also significantly faster (>10x on most models) than the MIP based attack which is also an exhaustive attack on activation space like ours (Table 1).",
        "evidence": "Setup. We evaluate our methods on all 10,000 test examples of and CI-FAR10 dataset, and select 9 models which are mostly benchmarking models used in previous works or competitions (details in Appendix A). For each model, we first run three commonly used strong adversarial attacks: a multi-targeted PGD (MT-PGD) attack with 100 Adam steps and 30 random restarts; a multi-targeted PGD attack with Output Diversified Sampling (ODS-PGD) with 100 Adam steps and 30 random restarts, and AutoAttack which is an ensemble of parameter-free attacks.\nThe remaining robust images are then tested with α,β-CROWN verifier to see if they can be verified robust so no further attack is needed. Any images that failed with the verifier are then evaluated in an MIP formulation  solved using Gurobi. The MIP solver is used as the last resort because it is usually much more expensive than other approaches. We set an one hour timeout for MIP attack and our BaB attack, but our attack usually terminates much faster than a generic MIP solver. Any instance that cannot be attacked via a combination of MT-PGD, ODS-PGD and AutoAttack nor verified is referred to as a hard instance, and the main evaluation is conducted on these instances. All attacks are ∞ norm-based with listed in Table. The hyperparameters can be found in Appendix A.2. Results. Table shows a breakdown of all 10,000 test examples on the 5 models. Among these models, MNIST Small-Adv, MNIST Conv-Small, CIFAR LP D -CNN-A, and LP D -ResNet are relatively easy, and most of datapoints can be either attacked or verified by SOTA tools. The LP D -CNN-A and LP D -ResNet models were among the largest ones in , however they have become quite easy due to the recent progress of neural network verifiers -only 2 and 1 (out of 10,000) examples are hard instances. On the relatively small MNIST Small-Adv model, a MIP solver can terminate within a reasonable amount of time, and we can attack the same number of images while being faster.\nOn the MNIST CNN-A-Adv model, many instances timeout with the MIP solver and we can attack more images under less time; see Fig. and Fig. (in Appendix) for time vs. number of images attacked. The CIFAR CNN-B-Adv, CNN-A-Mix, and Marabou models are much harder, and we managed to solve 5, 17, and 27 more images compared to MIP attack within much shorter time.\nBaB attack can solve the same number of images as MIP attack on MNIST Conv-Small and CIFAR CNN-A-Adv but is over 10x faster in average. For images that none of the attacks work, we plot the minimum margin between the ground-truth label and other labels in Fig. and compare the margins against ODS-PGD, MT-PGD attacks and AutoAttack. Our method consistently achieves smaller margins on all 6 models.\nComparison to more attacks. We compare our BaB attack to 5 state-of-the-art attacks on all hard instances in Table. Attacks we evaluated include 1) FAB attack): a whitebox boundary adversarial attack; 2) Square attack: a query-efficient black-box adversarial attack using randomized search with localized square-shaped updates; 3) DIFGSM attack: a white box attack leveraging input diversity; 4) MIFGSM attack: a momentum-based iterative white box attack to escape from poor local maxima and 5) Distributional attack: a white box attack considering adversarialdata distribution. We increased steps and iterations to make some attacks stronger; hyperparameters are in Appendix A.3. Most attacks are not effective on these hard instances. Square attack is the strongest among them but still finds less adversarial examples than us and is also relatively slow.\nAblation study. To fully understand how each proposed component contributes to the overall performance of BaB attack, we conduct ablation study on MNIST Small-Adv and MNIST CNN-A-Adv models and show the number of successfully attacked instances and average time in Table. We first show that the beam search guided by verifier α,β-CROWN significantly helps the performance compared to random top-down search without any guidance. We then show that the top-down diving and bottom-up large neighborhood search contribute to different hard instances and the combination of them lead to the best attack performance. Note that the average time here is on successfully attacked samples by each method only, showing the efficiency of each component instead of strength.\nAdversarial examples and attacks. Adversarial examples were first discovered in and they can be easily constructed by single-/multi-step gradient descent to fool regularly trained neural networks. However, purely gradient-based methods can fail due to gradient masking and obfuscated gradients. Popular attacks like PGD or CW 2018;  despite their empirically good performance and efficiency. A large body of white-box adversarial attacks have been proposed to strengthen adversarial attacks; many of them are variants of PGD based attacks. Due to non-convexity of the adversarial attack objective, gradient-free methods and black-box attacks are also widely explored but mostly result in similar or worse performance compared to gradient-based ones. Recently, stronger attacks are proposed but they are also restricted to searching in input space. In this paper, we are the first to conduct a systematic and efficient search of adversarial examples in activation space inspired by branch and bound techniques used for integer optimization and neural network verification.\nNeural network verification. Early neural network verifiers solve the verification problem with satisfiability modulo theories (SMT) or MIP solvers and can only scale to very small networks. Efficient verification methods with various sound relaxations are then proposed for verifying larger networks but without completeness guarantee. Branch and bound (BaB) based verifiers can efficiently branch on ReLU neurons and achieve completeness on ReLU networks using efficient incomplete verifiers. BaB based methods with input domain split and refinements are also investigated but they are limited to low input dimensions. Recent verifiers use GPU accelerated incomplete solvers to further scale up verification and achieve several orders of magnitude speedup. Our BaB attack relies on the lower bounds of BaB subdomains computed by α,β-CROWN, one of the most efficient GPU-based verifiers that won the second neural network verification competition (VNN-COMP 2021).\nTable 1: Comparison between MIP attack (Tjeng et al., 2019) (using Gurobi) and our BaB Attack. Both attacks focus on hard instances where a combination of MT-PGD, ODS-PGD and AutoAttack cannot attack and their robustness also cannot be verified using a verifier. We are faster than MIP Attack and can also find more adversarial examples in all models. Average time excludes examples where all methods time out.****Table 2: Number of successfully (# succ.) attacked hard i~nstances (from Table 1) under five more attacks.",

        "answer": "Home espresso machines are a growing segment of the small kitchen appliance market. A good home espresso machine provides the ability to make high quality espresso in a machine that is typically smaller and less expensive than their commercial counterparts. \n\nThere are three common espresso machine designs for home use: manual, semi-automatic, and fully automatic. As the name implies -- manual machines require direct \"manual\" control by the user, who typically applies pressure through a lever to deliver the desired brew pressure. Semi-automatic machines require the user to prepare the coffee into the portafilter, but then rely on an automated pump and to deliver the desired brew pressure for espresso. Fully automatic machines automate the entire process end-to-end: grinding the beans, loading the ground beans into the portafilter, and then pumping water through the portafilter at predefined pressure levels to brew espresso. \n\nManual machines typically have a lower cost, smaller footprint, and provide the user with more direct control over the brewing process. This allows skilled users to make higher-quality espresso than they would with a more automated machine. In contrast, fully automatic machines are often the easiest to use, but are unable to make espresso as consistently great as a skilled barista could with a manual machines. Fully automatic machines are inherently more complex, more expensive to purchase, and more likely to have longer-term reliability issues. \n\nRegardless of the type of espresso machine, two factors influence how well they will perform: their ability to manage brew temperature and brew pressure. The best machines provide the ability to vary brew temperature and pressure in consistent, repeatable ways.The type of coffee bean and desired result will impact what temperature and pressure profile the user wants.

        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31. Besides, when node B retweets node A we have an implicit confirmation that information from A appeared in B's Twitter feed BIBREF12. Quotes are simply a special case of retweets with comments.\nMentions usually include personal conversations as they allow someone to address a specific user or to refer to an individual in the third person; in the first case they are located at the beginning of a tweet and they are known as replies, otherwise they are put in the body of a tweet BIBREF20. The network of mentions is usually seen as a stronger version of interactions between Twitter users, compared to the traditional graph of follower/following relationships BIBREF32.\nWe used networkx Python package (Hagberg, Swart, and S Chult 2008) to compute all features.",

In short, the SpaceMAP has two major benefits: (1) SpaceMAP provides an explicit space transformation between LD and HD, while in contrast t-SNE or UMAP make highly implicit transformation, which may not fit the data (Figure 1 as an example). The explicity of space transformation by SpaceMAP, derived from geometrical measure, potentially better preserves the relative distance in the LD map and makes it possible to enforce data priors (i.e. when the intrinsic dimensionality in some cases is known, such as Swiss Roll). (2) The hierarchical formulation of SpaceMAP takes into consideration the local and global structure of the manifold, and is compatible to a wider range of datasets (disjoint or continuous, e.g. both MNIST and Swiss Roll). Furthermore, we have added more description to interpret the experiment results as suggested.",
        "evidence": "Dimensionality reduction (DR) and visualization of high-dimensional data is of theoretical and practical value in machine learning and related fields. In theory, there exists an intriguing, non-intuitive discrepancy between the geometry of highdimensional space and low-dimensional space. Based on this discrepancy, we propose a novel DR and visualization method called Space-based Manifold Approximation and Projection (SpaceMAP). Our method establishes a quantitative space transformation to address the \"crowding problem\" in DR. With the proposed equivalent extended distance (EED) and function distortion (FD) theory, we are able to match the capacity of high-dimensional and low-dimensional space in a principled manner. To handle complex high-dimensional data with different manifold properties, SpaceMAP makes distinctions between the near field, middle field, and far field of data distribution in a data-specific, hierarchical manner. We evaluated SpaceMAP on a range of artificial and real datasets with different manifold properties, and demonstrated its excellent performance in comparison with classical and state-of-the-art DR methods. In addition, the concept of space expansion provides a generic framework for understanding nonlinear DR methods including t-distributed Stochastic Neighbor Embedding (t-SNE) and Uniform Manifold Approximation and Projection (UMAP).\nWe applied the proposed SpaceMAP to a variety of datasets and computed quantitative metrics to evaluate the performance of DR. The method is benchmarked by other classical or state-of-the-art methods including PCA, Laplacian Eigenmaps, t-SNE, and UMAP.\nWe tested on a large range of high-dimensional datasets, including the standard MNIST, Fashion-MNIST, Swiss Roll (Van der Maaten et al., 2007) (Here we artificially created a hole on the Swiss Roll to challenge the DR methods if they can preserve the local property on a continuous manifold),, RNA-seq, and an experimental cardiac MRI dataset from three different vendors. Examples of cardiac MRI are given in Fig.. The details of the chosen datasets are in Appendix A.6. Here the original data is simply vectorized and taken as input of DR. We also tested all methods on the Google-News Word2Vec 3 Million dataset. For quantitative evaluation, we computed the 20-fold cross-validated k-nearest neighbor classifier accuracy (KNN accuracy), trustworthiness, continuity, Shepard goodness, and normalized stress to evaluate both the local and global structure preservation of the datasets. KNN accuracy measures the local structure preservation along different neighborhood scale k. Trustworthiness and continuity evaluate the local pattern of the embedding by calculating the true neighbor rate and the missing neighbor rate. The Shepard goodness and the normalized stress are two measurements of the goodness in global structure preservation. The detailed introduction of these evaluation metrics is in Appendix A.7.\nOur method establishes a quantitative space transformation to address the “crowding problem” in DR.

A collaboration profile containing these individual and pairwise features is built for each two interacting editors and is classified based on the agreement or disagreement relation between them. This intensive computation renders that classifier impractical. Table TABREF14 therefore also includes the most accurate classifier BIBREF4 consider practical.\nAs seen in Table TABREF14, for the usual 10-fold analysis the simple classifiers suggested here are on par with the best and more complex classifier reported in BIBREF4. Moreover, in the leave-one-category-out setting (Table TABREF14), accuracy indeed drops, but only marginally.

Win-win? :D”' –anonymous\nDogmatism describes the tendency to lay down opinions as incontrovertibly true, without respect for conflicting evidence or the opinions of others BIBREF0 . Which user is more dogmatic in the examples above? This question is simple for humans. Phrases like “they think” and “they don't even understand,” suggest an intractability of opinion, while “I think” and “win-win?” suggest the opposite. Can we train computers to draw similar distinctions? Work in psychology has called out many aspects of dogmatism that can be modeled computationally via natural language, such as over-confidence and strong emotions BIBREF1 .\nWe present a statistical model of dogmatism that addresses two complementary goals. First, we validate psychological theories by examining the predictive power of feature sets that guide the model's predictions. For example, do linguistic signals of certainty help to predict a post is dogmatic, as theory would suggest? Second, we apply our model to answer four questions:\nR1: What kinds of topics (e.g., guns, LGBT) attract the highest levels of dogmatism?\nR2: How do dogmatic beliefs cluster?\nR3: How does dogmatism influence a conversation on social media? R4: How do other user behaviors (e.g., frequency and breadth of posts) relate to dogmatism?\nWe train a predictive model to classify dogmatic posts from Reddit, one of the most popular discussion communities on the web. Posts on Reddit capture discussion and debate across a diverse set of domains and topics – users talk about everything from climate change and abortion, to world news and relationship advice, to the future of artificial intelligence. As a prerequisite to training our model, we have created a corpus of 5,000 Reddit posts annotated with levels of dogmatism, which we are releasing to share with other researchers.\nUsing the model, we operationalize key domain-independent aspects of psychological theories of dogmatism drawn from the literature. We find these features have predictive power that largely supports the underlying theory. For example, posts that use less confident language tend to be less dogmatic. We also discover evidence for new attributes of dogmatism. For example, dogmatic posts tend not to verbalize cognition, through terms such as “I think,” “possibly,” or “might be.”\nOur model is trained on only 5,000 annotated posts, but once trained, we use it to analyze millions of other Reddit posts to answer our research questions. We find a diverse set of topics are colored by dogmatic language (e.g., people are dogmatic about religion, but also about LGBT issues). Further, we find some evidence for dogmatism as a deeper personality trait – people who are strongly dogmatic about one topic are more likely to express dogmatic views about others as well. Finally, in conversation, we discover that one user's dogmatism tends to bring out dogmatism in their conversational partner, forming a vicious cycle.\nOur model is trained on only 5,000 annotated posts, but once trained, we use it to analyze millions of other Reddit posts to answer our research questions.",

Recent tasks such as visual question answering BIBREF9 , image captioning BIBREF10 , and audio-video classification BIBREF11 make steps towards learning from multiple modalities but lack the dynamic, responsive signal from exploratory learning. Modern, challenging tasks incorporating interaction, such as Atari BIBREF12 and Go BIBREF13 , push agents to learn complex strategies through trial-and-error but miss information-rich connections across vision, language, sounds, and actions.

For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nIn this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.",

        "evidence": "Machine reading comprehension and question answering has becomes a crucial application problem in evaluating the progress of AI system in the realm of natural language processing and understanding BIBREF0 . The computational linguistics communities have devoted significant attention to the general problem of machine reading comprehension and question answering.\nHowever, most of existing reading comprehension tasks only focus on shallow QA tasks that can be tackled very effectively by existing retrieval-based techniques BIBREF1 . For example, recently we have seen increased interest in constructing extractive machine reading comprehension datasets such as SQuAD BIBREF2 and NewsQA BIBREF3 . Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nIn this paper, we focus on multi-choice MRC task such as ROCStories ( ?), COIN Shared Task 1 ( ?) and RACE (Lai et al. , 2017) which requests to choose the right answer from a set of candidate ones according to given passage and question.",

        "answer": "Bayesian Inference differs from other machine learning techniques by introducing a distribution p(ξ) over the parameters of the model.",
        "evidence": "Bayesian Inference differs from other machine learning techniques by introducing a distribution INLINEFORM0 over the parameters of the model. A major concern in Bayesian Inference is usually to define a prior that makes as little assumption as possible. Such a prior is usually known as uninformative prior. Having a completely uninformative prior has the practical advantage that the prior distribution will have a minimal impact on the outcome of the inference leading to a model which bases its prediction purely and solely on the data. In the present work, we aim at the opposite behavior, we wish our AUD model to learn phone-like units from the unlabeled speech data of a target language given the knowledge that was previously accumulated from another resourceful language. More formally, the original AUD model training consists in estimate the a posteriori distribution of the parameters given the unlabeled speech data of a target language INLINEFORM1 : DISPLAYFORM0 \nThe parameters are divided into two subgroups INLINEFORM0 where INLINEFORM1 are the global parameters of the model, and INLINEFORM2 are the latent variables which, in our case, correspond to the sequences of acoustic units. The global parameters are separated into two independent subsets : INLINEFORM3 , corresponding to the acoustic parameters ( INLINEFORM4 ) and the \"phonotactic\" language model parameters ( INLINEFORM5 ). Replacing INLINEFORM6 and following the conditional independence of the variable induced by the model (see BIBREF1 for details) leads to: DISPLAYFORM0 \nIf we further assume that we have at our disposal speech data in a different language than the target one, denoted INLINEFORM0 , along with its phonetic transcription INLINEFORM1 , it is then straightforward to show that: DISPLAYFORM0 \n which is the same as Eq. EQREF8 but for the distribution of the acoustic parameters which is based on the data of the resourceful language. In contrast of the term uninformative prior we denote INLINEFORM0 as an informative prior. As illustrated by Eq. EQREF9 , a characteristic of Bayesian inference is that it naturally leads to a sequential inference. Therefore, model training can be summarized as:\nPractically, the computation of the informative prior as well as the final posterior distribution is intractable and we seek for an approximation by means of the well known Variational Bayes Inference BIBREF12 . The approximate informative prior INLINEFORM0 is estimated by optimizing the variational lower bound of the evidence of the prior data INLINEFORM1 : DISPLAYFORM0 \nwhere INLINEFORM0 is the Kullback-Leibler divergence. Then, the posterior distribution of the parameters given the target data INLINEFORM1 can be estimated by optimizing the evidence of the target data INLINEFORM2 : DISPLAYFORM0 \nNote that when the model is trained with an uninformative prior the loss function is the as in Eq. EQREF13 but with INLINEFORM0 instead of the INLINEFORM1 . For the case of the uninformative prior, the Variational Bayes Inference was initialized as described in BIBREF1 . In the informative prior case, we initialized the algorithm by setting INLINEFORM2 .\nBayesian Inference differs from other machine learning techniques by introducing a distribution p(ξ) over the parameters of the model.",

So then what is the benefit of the additional effort of training on the source data? Especially considering that it requires additional computational resources. Clearly, the performance on the source data is worse for TO-KD, but how important is that for the device?",
        "answer": "Both TO-KD and STU-KD are developed in this paper. They adopt the same method (i.e., lite residual hypothesis transfer and knowledge distillation) to adapt the compact model to the target data. Thus, the performance of these two schemes are similar in terms of the inference accuracy on the target data. If the compact model is not trained over the source data (like the procedure in TO-KD), then it is only adapted to the target data while forgetting the knowledge of the source data. When some source data occur in the new environment, the compact model trained by TO-KD can suffer low inference accuracy on these source data. More specifically, the inference accuracy on the source data is reduced by up to 17% as shown in our experimental results. Such phenomenon is undesired for any image recognition application. Considering a mobile robot that works in a manufacturing factory with many different working zones, it needs to recognize the objects, e.g., machines, tools, and human in these working zones. Initially, the compact machine learning model on the robot is built based on the labeled images taken in some of the working zones (i.e., the source data). For the sake of clarity, these zones are defined as source zones, and the rest zones are defined as target zones. When the robot moves to a target zone, its compact model needs to be adapted to the images from these zones (i.e., the target data), so as to ensure high inference accuracy. However, if the compact model is only adapted to the target data without being trained over the source data, it can forget the knowledge of the source data. Thus, after domain adaptation, when the robot moves back to a source zone, the performance of the compact model degrades. By training the compact model over the source data during domain adaptation, the knowledge of the source data can be maintained by the compact model. As a result, the compact model trained by STU-KD achieves high inference accuracy on both the target data and the source data. More specifically, the corresponding inference accuracy on the source data is comparable to that of the compact model before domain adaptation, according to our experimental results.",

        "evidence": "This intuition inspired the TransE model—a well-known embedding model for KB completion or link prediction in KBs BIBREF2 .\nEmbedding models for KB completion have been proven to give state-of-the-art link prediction performances, in which entities are represented by latent feature vectors while relation types are represented by latent feature vectors and/or matrices and/or third-order tensors BIBREF24 , BIBREF25 , BIBREF2 , BIBREF26 , BIBREF27 , BIBREF28 , BIBREF29 , BIBREF19 , BIBREF30 , BIBREF3 , BIBREF31 , BIBREF32 , BIBREF33 . This article briefly overviews the embedding models for KB completion, and then summarizes up-to-date experimental results on two standard evaluation tasks: i) the entity prediction task—which is also referred to as the link prediction task BIBREF2 —and ii) the triple classification task BIBREF34 .\nThe Unstructured model BIBREF22 assumes that the head and tail entity vectors are similar. As the Unstructured model does not take the relationship into account, it cannot distinguish different relation types. The Structured Embedding (SE) model BIBREF35 assumes that the head and tail entities are similar only in a relation-dependent subspace, where each relation is represented by two different matrices. Furthermore, the SME model BIBREF22 uses four different matrices to project entity and relation vectors into a subspace. The TransE model BIBREF2 is inspired by models such as the Word2Vec Skip-gram model BIBREF0 where relationships between words often correspond to translations in latent feature space. TorusE BIBREF36 embeds entities and relations on a torus to handle TransE's regularization problem.\nThe TransH model BIBREF26 associates each relation with a relation-specific hyperplane and uses a projection vector to project entity vectors onto that hyperplane. TransD BIBREF37 and TransR/CTransR BIBREF28 extend the TransH model by using two projection vectors and a matrix to project entity vectors into a relation-specific space, respectively. Similar to TransR, TransR-FT BIBREF38 also uses a matrix to project head and tail entity vectors. TEKE_H BIBREF39 extends TransH to incorporate rich context information in an external text corpus. lppTransD BIBREF40 extends TransD to additionally use two projection vectors for representing each relation. STransE BIBREF41 and TranSparse BIBREF42 can be viewed as direct extensions of the TransR model, where head and tail entities are associated with their own projection matrices. Unlike STransE, the TranSparse model uses adaptive sparse matrices, whose sparse degrees are defined based on the number of entities linked by relations. TranSparse-DT BIBREF43 is an extension of TranSparse with a dynamic translation. ITransF BIBREF44 can be considered as a generalization of STransE, which allows sharing statistic regularities between relation projection matrices and alleviates data sparsity issue.\nDISTMULT BIBREF45 is based on the Bilinear model BIBREF24 , BIBREF22 , BIBREF25 where each relation is represented by a diagonal rather than a full matrix. The neural tensor network (NTN) model BIBREF34 uses a bilinear tensor operator to represent each relation while ER-MLP BIBREF27 and ProjE BIBREF46 can be viewed as simplified versions of NTN. Such quadratic forms are also used to model entities and relations in KG2E BIBREF47 , TransG BIBREF48 , ComplEx BIBREF31 , TATEC BIBREF3 , RSTE BIBREF49 and ANALOGY BIBREF50 . In addition, the HolE model BIBREF33 uses circular correlation–a compositional operator–which can be interpreted as a compression of the tensor product.\nConvE BIBREF51 and ConvKB BIBREF52 are based on convolutional neural networks. ConvE uses a 2D convolutional layer directly over head-entity and relation vector embeddings while ConvKB applies a convolutional layer over embedding triples. Unlike ConvE and ConvKB, the IRN model BIBREF53 uses a shared memory and recurrent neural network-based controller to implicitly model multi-step structured relationships.\nThe Path Ranking Algorithm (PRA) BIBREF21 is a random walk inference technique which was proposed to predict a new relationship between two entities in KBs. BIBREF61 used PRA to estimate the probability of an unseen triple as a combination of weighted random walks that follow different paths linking the head entity and tail entity in the KB. BIBREF23 made use of an external text corpus to increase the connectivity of the KB used as the input to PRA. BIBREF62 improved PRA by proposing a subgraph feature extraction technique to make the generation of random walks in KBs more efficient and expressive, while BIBREF63 extended PRA to couple the path ranking of multiple relations. PRA can also be used in conjunction with first-order logic in the discriminative Gaifman model BIBREF64 . In addition, BIBREF65 used a recurrent neural network to learn vector representations of PRA-style relation paths between entities in the KB. Other random-walk based learning algorithms for KB completion can be also found in BIBREF66 , BIBREF67 , BIBREF68 and BIBREF69 . Recently, BIBREF70 have proposed a Neural Logic Programming (LP) framework to learning probabilistic first-order logical rules for KB reasoning, producing competitive link prediction performances.

If no candidate achieves an absolute majority there, a contingent election is held by the House of Representatives to elect the president and by the Senate to elect the vice president.\nThe states and the District of Columbia hold a statewide or districtwide popular vote on Election Day in November to choose electors based upon how they have pledged to vote for president and vice president, with some state laws proscribing faithless electors. All states except Maine and Nebraska use a party block voting, or general ticket method, to choose their electors, meaning all their electors go to one winning ticket. Maine and Nebraska choose one elector per congressional district and two electors for the ticket with the highest statewide vote. The electors meet and vote in December, and the inauguration of the president and vice president takes place in January.",

        "question": "The fire / burning house example confuses me because I do not see how it makes a case for using actual causation. Do you mean that F = 1 is not actual cause of B = 0 while F = 0 is?",
        "answer": "Yes, that is indeed what I mean, and I should mention this explicitly. The structure of this example is a common one in the literature on actual causation.",
        "evidence": "Actual Causes are those events which explain an output in the most general sense of explanation.\nThere is a lively literature on how to define actual causation using causal models, but for the reasons outlined above, this literature has yet to find its way into the XAI literature. I here aim to set this straight by explicitly connecting actual causation to the notions of explanation that we have come across. A concise counterfactual explanation is good when you can get it, but often you cannot get it, and thus we need a weaker notion of explanation that is more generally applicable. 7 (The causal counterpart of this message is what initiated the formal causation literature some fifty years ago.)\nIt is clear from the definitions that sufficient explanations are weaker than counterfactual explanations. But sufficient explanations ignore the counterfactual aspect entirely, which means they are of little value for action-guidance in the presence of an already existing observation. Therefore I define actual causes as parts of explanations that sit in between counterfactual and sufficient explanations: they are parts of good sufficient explanations such that there exist counterfactual values which would not have made the explanation better. This is weaker than demanding that the counterfactual values are part of a sufficient explanation of a different output, as we do for counterfactual explanations. Informally, X = x rather than X = x is an actual cause of Y = y if X = x is part of a good sufficient explanation for Y = y that could have not been made better by setting X to x .\nFirst I make precise how changing the values of some variables can turn a sufficient explanation into a better one.\nDefinition 18 If ((X = x, W = w), N ) is a sufficient explanation of Y = y, we say that X = x can replace X = x if there exists a dominating explanation that includes (X = x , W = w).\nThe following result ensures that the focus on W (instead of its subsets) in Definition 18 is without loss of generality.\nProposition 19 If ((X = x, W = w), N ) is a sufficient explanation of Y = y and there exists a dominating explanation ((X = x , A = a), B) for some values x and a ⊆ w, then X = x can replace X = x.\nDefinition 20 X = x rather than X = x is an actual cause of Y = y in (M, u) if it is part of a good sufficient explanation of Y = y in which X = x cannot be replaced by X = x .\nIf ((X = x, W = w), N ) is the relevant good explanation, we say that X = x rather than X = x is an actual cause of Y = y relative to (W = w, N ).\n6. Obviously this holds only if V \\ (X ∪ {Y }) consists of at least two elements. 7. Obviously you can always find some counterfactual explanation of an output, for changing all of the variables will always allow you to get a different output. But an explanation that involves too many variables is of little use.\nExcept for a minor technical difference regarding the implementation of minimality, Definition 20 is equivalent to the definition of causation I developed in previous work. Although I have here arrived at the same notion, I did so along a very different path, for in the previous work I did not draw any connection to explanations nor to action-guidance, but instead argued for the definition by contrasting it to other proposals for defining causation (including Definition 13).\nContrary to counterfactual explanations, actual causes do not guide you towards actions that, under the same conditions, would ensure the output to be different. But they do guide you towards actions that would not ensure the actual output under the same conditions as the actual action. For example, imagine a (very fortunate) applicant for whom X 1 = 250, 000, X 3 = 50, 000, and thus X 2 = 125, 000. Obviously their application is successful, and their income by itself offers a good explanation of this fact: X 1 = 250, 000 is a good direct sufficient explanation of Y = 1. Also, their income does not counterfactually explain the output, for the application would have been approved regardless of income. Yet we do have that X 1 = 250, 000 rather than X 1 = 200, 000 is an actual cause of the output, because we cannot replace X 1 = 250, 000 by X 1 = 200, 000 in our sufficient explanation (i.e., X 1 = 200, 000 is not a sufficient explanation of Y = 1). This is helpful for example if the applicant is considering changing jobs and would like to know whether they can use up their savings and still get their application approved.\nOne might wonder whether we need a separate definition of actual causation, as opposed to simply considering all parts of good sufficient explanations to be causes. The distinction between these two options lies in the existence of alternative actions that would make the actual explanation worse, and it are precisely those actions which make actual causes good guides towards action. Consider for example a situation in which a short-circuit starts a fire (F = 1) in an office building. The flames set off the sprinklers (S = 1), and those put out the flames, preventing the building from burning down (B = 0) -where all variables are binary. Matching equations for this story are: B = F ∧ ¬S, S = F . In this scenario, the fire offers a good sufficient explanation of the building not burning down relative to the sprinklers functioning as they should. But obviously it would be unwise to conclude from this that we should start fires in order to prevent buildings from burning down! This point can be brought out by noting that the fire is not an actual cause of the building not burning down, because there not being a fire would have offered a better sufficient explanation of this outcome, as it does not rely on the sprinklers functioning properly. (Concretely: F = 0 can replace F = 1 in the good sufficient explanation (F = 1, S) of B = 0.) Since sprinklers can malfunction, or can be made to malfunction by a malicious actor, the best action is to not set fires in a building, in accordance with actual causation.\nThe following result specifies the claim that actual causes sit in between counterfactual and sufficient explanations: counterfactual explanations always contain actual causes (and obviously not vice versa).\nTheorem 21 If X 1 = x 1 rather than X 1 = x 1 is a counterfactual explanation of Y = y in (M, u) (relative to some (W = w, N )) then for some X 2 ⊆ X 1 , X 2 = x 2 rather than X 2 = x 2 is an actual cause of Y = y in (M, u) (where x 2 and x 2 are the relevant restrictions to X 2 ).\nAn obvious strengthening of actual causation is to replace the existential quantifier over counterfactual values with a universal one, so that the actual values are the optimal values in terms of explanations.\nDefinition 22 X = x is an optimal cause of Y = y in (M, u) if X = x is part of a good sufficient explanation of Y = y in which X = x cannot be replaced. (I.e., there do not exist values x so that it could be replaced by those.)\nFinally, replacing strong sufficiency with direct sufficiency offers a notion of direct causation .\nWe can now present a final result regarding the limitation of Independence: the different notions of causation also reduce to each other.\nTheorem 25 If a causal model M satisfies Independence then the following statements are all equivalent:\n• there exist values x so that X = x rather than X = x is an actual cause of Y = y in (M, u).\n• X = x is part of a good sufficient explanation of Y = y in (M, u).\n(Concretely: F = 0 can replace F = 1 in the good sufficient explanation (F = 1, S) of B = 0.)",

        "answer": "Hugo Rafael Chávez Frías (Spanish pronunciation: [ˈuɣo rafaˈel ˈtʃaβes ˈfɾi.as] (listen); 28 July 1954 – 5 March 2013) was a Venezuelan politician who was president of Venezuela from 1999 until his death in 2013, except for a brief period in 2002. Chávez was also leader of the Fifth Republic Movement political party from its foundation in 1997 until 2007, when it merged with several other parties to form the United Socialist Party of Venezuela (PSUV), which he led until 2012.\n\nBorn into a middle-class family in Sabaneta, Barinas, Chávez became a career military officer and, after becoming dissatisfied with the Venezuelan political system based on the Puntofijo Pact, he founded the clandestine Revolutionary Bolivarian Movement-200 (MBR-200) in the early 1980s. Chávez led the MBR-200 in its unsuccessful coup d'état against the Democratic Action government of President Carlos Andrés Pérez in 1992, for which he was imprisoned. Pardoned from prison two years later, he founded the Fifth Republic Movement political party, and then receiving 56.2% of the vote, was elected president of Venezuela in 1998. He was re-elected in 2000 with 59.8% of the vote and again in 2006 with 62.8% of the vote. After winning his fourth term as president in the October 2012 presidential election with a decrease to 55.1% of the vote, he was to be sworn in on 10 January 2013. However, the inauguration was postponed due to his cancer treatment, and on 5 March at age 58, he died in Caracas.\n\nFollowing the adoption of a new constitution in 1999, Chávez focused on supposedly enacting social reforms as part of the Bolivarian Revolution. Using record-high oil revenues of the 2000s, his government nationalized key industries, created participatory democratic Communal Councils and implemented social programs known as the Bolivarian missions to expand access to food, housing, healthcare and education. The high oil profits coinciding with the start of Chavez's presidency resulted in temporary improvements in areas such as poverty, literacy, income equality and quality of life between primarily 2003 and 2007, though extensive changes in structural inequalities did not occur. On 2 June 2010, Chávez declared an \"economic war\" on Venezuela's upper classes due to shortages, arguably beginning the crisis in Venezuela. By the end of Chávez's presidency in the early 2010s, economic actions performed by his government during the preceding decade, such as deficit spending and price controls, proved to be unsustainable, with Venezuela's economy faltering. At the same time, poverty, inflation and shortages increased.\n\nUnder Chávez, Venezuela experienced democratic backsliding, as he suppressed the press, manipulated electoral laws, and arrested and exiled government critics. His use of enabling acts and his government's use of propaganda were controversial. Chávez's presidency saw significant increases in the country's murder rate[page needed] and continued corruption within the police force and government.\n\nAcross the political spectrum, Chávez is regarded as one of the most influential and controversial politicians in the modern history of Venezuela and Latin America. His 14-year presidency marked the start of the socialist \"pink tide\" sweeping Latin America—he supported Latin American and Caribbean cooperation and was instrumental in setting up the pan-regional Union of South American Nations, the Community of Latin American and Caribbean States, the Bolivarian Alliance for the Americas, the Bank of the South and the regional television network TeleSUR. Internationally, Chávez aligned himself with the Marxist–Leninist governments of Fidel and then Raúl Castro in Cuba, as well as the socialist governments of Evo Morales in Bolivia, Rafael Correa in Ecuador and Daniel Ortega in Nicaragua. Chávez's ideas, programs, and style form the basis of \"Chavismo\", a political ideology closely associated with Bolivarianism and socialism of the 21st century. Chávez described his policies as anti-imperialist, being a prominent adversary of the United States's foreign policy as well as a vocal critic of neoliberalism and laissez-faire capitalism. He described himself as a Marxist.",

Going one step further, emotion cause extraction can reveal important information about what causes a certain emotion and why there is an emotion change. In this section, we introduce related work on emotion analysis including emotion cause extraction.\nIn emotion analysis, we first need to determine the taxonomy of emotions. Researchers have proposed a list of primary emotions BIBREF7 , BIBREF8 , BIBREF9 . In this study, we adopt Ekman's emotion classification scheme BIBREF8 , which identifies six primary emotions, namely happiness, sadness, fear, anger, disgust and surprise, as known as the “Big6” scheme in the W3C Emotion Markup Language. This emotion classification scheme is agreed upon by most previous works in Chinese emotion analysis.\nExisting work in emotion analysis mostly focuses on emotion classification BIBREF10 , BIBREF11 and emotion information extraction BIBREF12 . xu2012coarse used a coarse to fine method to classify emotions in Chinese blogs. gao2013joint proposed a joint model to co-train a polarity classifier and an emotion classifier. beck2014joint proposed a Multi-task Gaussian-process based method for emotion classification. chang2015linguistic used linguistic templates to predict reader's emotions. das2010finding used an unsupervised method to extract emotion feelers from Bengali blogs. There are other studies which focused on joint learning of sentiments BIBREF13 , BIBREF14 or emotions in tweets or blogs BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 , BIBREF19 , and emotion lexicon construction BIBREF20 , BIBREF21 , BIBREF22 . However, the aforementioned work all focused on analysis of emotion expressions rather than emotion causes.\nlee2010text first proposed a task on emotion cause extraction. They manually constructed a corpus from the Academia Sinica Balanced Chinese Corpus. Based on this corpus, chen2010emotion proposed a rule based method to detect emotion causes based on manually define linguistic rules. Some studies BIBREF23 , BIBREF24 , BIBREF25 extended the rule based method to informal text in Weibo text (Chinese tweets).\nOther than rule based methods, russo2011emocause proposed a crowdsourcing method to construct a common-sense knowledge base which is related to emotion causes. But it is challenging to extend the common-sense knowledge base automatically. ghazi2015detecting used Conditional Random Fields (CRFs) to extract emotion causes. However, it requires emotion cause and emotion keywords to be in the same sentence. More recently, gui2016event proposed a multi-kernel based method to extract emotion causes through learning from a manually annotated emotion cause dataset.\n[id=lq]Most existing work does not consider the relation between an emotion word and the cause of such an emotion, or they simply use the emotion word as a feature in their model learning. Since emotion cause extraction requires an understanding of a given piece of text in order to correctly identify the relation between the description of an event which causes an emotion and the expression of that emotion, it can essentially be considered as a QA task. In our work, we choose the memory network, which is designed to model the relation between a story and a query for QA systems BIBREF26 , BIBREF27 . Apart from its application in QA, memory network has also achieved great successes in other NLP tasks, such as machine translation BIBREF28 , sentiment analysis BIBREF29 or summarization BIBREF30 . To the best of our knowledge, this is the first work which uses memory network for emotion cause extraction.\nMost existing work does not consider the relation between an emotion word and the cause of such an emotion, or they simply use the emotion word as a feature in their model learning.",

        "answer": "The two annotated categories were on-topic persuasive and non persuasive.",
        "evidence": "The goal of this study was to select documents suitable for a fine-grained analysis of arguments. In a preliminary study on annotating argumentation using a small sample (50 random documents) of forum posts and comments from the raw corpus, we found that many documents convey no argumentation at all, even in discussions about controversies. We observed that such contributions do not intend to persuade; these documents typically contain story-sharing, personal worries, user interaction (asking questions, expressing agreement), off-topic comments, and others. Such characteristics are typical to on-line discussions in general, but they have not been examined with respect to argumentation or persuasion. Indeed, we observed that there are (1) documents that are completely unrelated and (2) documents that are related to the topic, but do not contain any argumentation. This issue has been identified among argumentation theorist; for example as external relevance by Paglieri.Castelfranchia.2014. Similar findings were also confirmed in related literature in argumentation mining, however never tackled empirically BIBREF53 , BIBREF8 These documents are thus not suitable for analyzing argumentation.\nIn order to filter documents that are suitable for argumentation annotation, we defined a binary document-level classification task. The distinction is made between either persuasive documents or non-persuasive (which includes all other sorts of texts, such as off-topic, story sharing, unrelated dialog acts, etc.).\nThe two annotated categories were on-topic persuasive and non-persuasive. Three annotators with near-native English proficiency annotated a set of 990 documents (a random subset of comments and forum posts) reaching 0.59 Fleiss' INLINEFORM0 . The final label was selected by majority voting. The annotation study took on average of 15 hours per annotator with approximately 55 annotated documents per hour. The resulting labels were derived by majority voting. Out of 990 documents, 524 (53%) were labeled as on-topic persuasive. We will refer to this corpus as gold data persuasive.\nWe examined all disagreements between annotators and discovered some typical problems, such as implicitness or topic relevance. First, the authors often express their stance towards the topic implicitly, so it must be inferred by the reader. To do so, certain common-ground knowledge is required. However, such knowledge heavily depends on many aspects, such as the reader's familiarity with the topic or her cultural background, as well as the context of the source website or the discussion forum thread. This also applies for sarcasm and irony. Second, the decision whether a particular topic is persuasive was always made with respect to the controversial topic under examination. Some authors shift the focus to a particular aspect of the given controversy or a related issue, making the document less relevant.\nWe achieved moderate agreement between the annotators, although the definition of persuasiveness annotation might seem a bit fuzzy. We found different amounts of persuasion in the specific topics. For instance, prayer in schools or private vs. public schools attract persuasive discourse, while other discussed controversies often contain non-persuasive discussions, represented by redshirting and mainstreaming. Although these two topics are also highly controversial, the participants of on-line discussions seem to not attempt to persuade but they rather exchange information, support others in their decisions, etc. This was also confirmed by socio-psychological researchers. Ammari.et.al.2014 show that parents of children with special needs rely on discussion sites for accessing information and social support and that, in particular, posts containing humor, achievement, or treatment suggestions are perceived to be more socially appropriate than posts containing judgment, violence, or social comparisons. According to Nicholson.Leask.2012, in the online forum, parents of autistic children were seen to understand the issue because they had lived it. Assuming that participants in discussions related to young kids (e.g., redshirting, or mainstreaming) are usually females (mothers), the gender can also play a role. In a study of online persuasion, Guadagno.Cialdini.2002 conclude that women chose to bond rather than compete (women feel more comfortable cooperating, even in a competitive environment), whereas men are motivated to compete if necessary to achieve independence.\nThe two annotated categories were on-topic persuasive and non persuasive.",

        "answer": "Potentially more generalizable.",
        "evidence": "Named entity recognition (NER) BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc. NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction BIBREF4 , machine translation BIBREF5 , question answering BIBREF6 and knowledge base construction BIBREF7 . Although early NER systems have been successful in producing adequate recognition accuracy, they often require significant human effort in carefully designing rules or features.\nIn recent years, deep learning methods been employed in NER systems, yielding state-of-the-art performance. However, the number of types detected are still not sufficient for certain domain-specific applications. For relation extraction, identifying fine-grained types has been shown to significantly increase the performance of the extractor BIBREF8 , BIBREF9 since this helps in filtering out candidate relation types which do not follow this type constraint. Furthermore, for question answering fine-grained Named Entity Recognition (FgNER) can provide additional information helping to match questions to its potential answers thus improving performance BIBREF10 . For example, Li and Roth BIBREF11 rank questions based on their expected answer types (i.e. will the answer be food, vehicle or disease).\nTypically, FgNER systems use over a hundred labels, arranged in a hierarchical structure. We find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process. Furthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task. Currently, FgNER systems use distant supervision BIBREF12 to automatically generate training data. Distant supervision is a technique which maps each entity in the corpus to knowledge bases such as Freebase BIBREF13 , DBpedia BIBREF14 , YAGO BIBREF15 and helps with the generation of labeled data. This method will assign the same set of labels to all mentions of a particular entity in the corpus. For example, “Barack Obama” is a person, politician, lawyer, and author. If a knowledge base has these four matching labels, the distant supervision technique will assign all of them to every mention of “Barack Obama”. Therefore, the training data will also fail to distinguish between mentions of “Barack Obama” in all subsequent utterances.\nLing et al. ling2012fine proposed the first system for FgNER, where they used 112 overlapping labels with a linear classifier perceptron for multi-label classification. Yosef et al. spaniol2012hyena used multiple binary SVM classifiers to assign entities to a set of 505 types. Gillick et al. gillick2014context introduced context dependent FgNER and proposed a set of heuristics for pruning labels that might not be relevant given the local context of the entity. Yogatama et al. yogatama2015embedding proposed an embedding based model where user-defined features and labels were embedded into a low dimensional feature space to facilitate information sharing among labels.\nShimaoka et al. shimaoka2016attentive proposed an attentive neural network model which used long short-term memory (LSTMs) to encode the context of the entity, then used an attention mechanism to allow the model to focus on relevant expressions in the entity mention's context. To learn entity representations, we propose a scheme which is potentially more generalizable.\nTo learn entity representations, we propose a scheme which is potentially more generalizable.",

        "question": "What's Jiang's theoretical contribution?",
        "evidence": "Jiang Zemin (17 August 1926 – 30 November 2022) was a Chinese politician who served as general secretary of the Chinese Communist Party (CCP) from 1989 to 2002, as chairman of the Central Military Commission from 1989 to 2004, and as president of China from 1993 to 2003. Jiang was paramount leader of China from 1989 to 2002. He was the core leader of the third generation of Chinese leadership, one of four core leaders alongside Mao Zedong, Deng Xiaoping and Xi Jinping.\n\nBorn in Yangzhou, Jiangsu, Jiang joined the CCP while he was in college. After the establishment of the People's Republic of China in 1949, he received training at the Stalin Automobile Works in Moscow in the 1950s, later returning to Shanghai in 1962 to serve in various institutes, later being sent between 1970-1972 to Romania as part of an expert team to establish machinery manufacturing plants in the country. After 1979, he was appointed as the vice chair of two commissions by vice premier Gu Mu to oversee the newly-established special economic zones (SEZs). He became the vice minister of the newly-established Ministry of Electronics Industry and a member of the CCP Central Committee in 1982.\n\nJiang was appointed as the mayor of Shanghai in 1985, later being promoted to its Communist Party secretary, as well as a member of the CCP Politburo, in 1987. Jiang came to power unexpectedly as a compromise candidate following the 1989 Tiananmen Square protests and massacre, when he replaced Zhao Ziyang as CCP general secretary after Zhao was ousted for his support for the student movement. As the involvement of the \"Eight Elders\" in Chinese politics steadily declined, Jiang consolidated his hold on power to become the \"paramount leader\" in the country during the 1990s. Urged by Deng Xiaoping's southern tour in 1992, Jiang officially introduced the term \"socialist market economy\" in his speech during the 14th CCP National Congress held later that year, which accelerated \"opening up and reform\".\n\nUnder Jiang's leadership, China experienced substantial economic growth with the continuation of market reforms. The returning of Hong Kong from the United Kingdom in 1997 and of Macau from Portugal in 1999, and entry into the World Trade Organisation in 2001, were landmark moments of his era. China also witnessed improved relations with the outside world, while the Communist Party maintained its tight control over the state. Jiang faced criticism over human rights abuses, including the crackdown on the Falun Gong movement. His contributions to party doctrine, known as the \"Three Represents\", were written into the CCP constitution in 2002. Jiang gradually vacated his official leadership titles from 2002 to 2005, being succeeded in these roles by Hu Jintao, although he and his political faction continued to influence affairs until much later. On 30 November 2022, Jiang died from leukemia and multiple organ failure in Shanghai.",

        "answer": "What pages were captured, which are likely missing, and why.",
        "evidence": "Many scholars in the humanities and the social sciences work with sources that are not available in digital form, and indeed may never be digitized. Others work with both analogue and digitized materials, and the increasing digitization of archives has opened opportunities to study these archives in new ways. We can go to the canonical archive or open up something that nobody has studied before. For example, we might focus on major historical moments (French Revolution, post-Milosevic Serbia) or critical epochs (Britain entering the Victorian era, the transition from Latin to proto-Romance). Or, we could look for records of how people conducted science, wrote and consumed literature, and worked out their philosophies.\nA growing number of researchers work with born-digital sources or data. Born-digital data, e.g., from social media, generally do not involve direct elicitation from participants and therefore enable unobtrusive measurements BIBREF5 , BIBREF6 . In contrast, methods like surveys sometimes elicit altered responses from participants, who might adapt their responses to what they think is expected. Moreover, born-digital data is often massive, enabling large-scale studies of language and behavior in a variety of social contexts.\nStill, many scholars in the social sciences and humanities work with multiple data sources. The variety of sources typically used means that more than one data collection method is often required. For example, a project examining coverage of a UK General Election, could draw data from traditional media, web archives, Twitter and Facebook, campaign manifestos, etc. and might combine textual analysis of these materials with surveys, laboratory experiments, or field observations offline. In contrast, many computational studies based on born-digital data have focused on one specific source, such as Twitter.\nThe use of born-digital data raises ethical concerns. Although early studies often treated privacy as a binary construct, many now acknowledge its complexity BIBREF7 . Conversations on private matters can be posted online, visible for all, but social norms regarding what should be considered public information may differ from the data's explicit visibility settings. Often no informed consent has been obtained, raising concerns and challenges regarding publishing content and potentially harmful secondary uses BIBREF8 , BIBREF4 .\nRecently, concerns about potential harms stemming from secondary uses have led a number of digital service providers to restrict access to born-digital data. Facebook and Twitter, for example, have reduced or eliminated public access to their application programming interfaces (APIs) and expressed hesitation about allowing academic researchers to use data from their platforms to examine certain sensitive or controversial topics. Despite the seeming abundance of born-digital data, we therefore cannot take its availability for granted.\nWorking with data that someone else has acquired presents additional problems related to provenance and contextualisation. It may not always be possible to determine the criteria applied during the creation process. For example, why were certain newspapers digitized but not others, and what does this say about the collection? Similar questions arise with the use of born-digital data. For instance, when using the Internet Archive’s Wayback Machine to gather data from archived web pages, we need to consider what pages were captured, which are likely missing, and why.\nWe must often repurpose born-digital data (e.g., Twitter was not designed to measure public opinion), but data biases may lead to spurious results and limit justification for generalization. In particular, data collected via black box APIs designed for commercial, not research, purposes are likely to introduce biases into the inferences we draw, and the closed nature of these APIs means we rarely know what biases are introduced, let alone how severely they might impact our research BIBREF10 . These, however, are not new problems. Historians, for example, have always understood that their sources were produced within particular contexts and for particular purposes, which are not always apparent to us.\nNon-representative data can still be useful for making comparisons within a sample. In the introductory example on hate speech BIBREF0 , the Reddit forums do not present a comprehensive or balanced picture of hate speech: the writing is almost exclusively in English, the targets of hate speech are mainly restricted (e.g., to black people, or women), and the population of writers is shaped by Reddit's demographics, which skew towards young white men. These biases limit the generalizability of the findings, which cannot be extrapolated to other languages, other types of hate speech, and other demographic groups. However, because the findings are based on measurements on the same sort of hate speech and the same population of writers, as long as the collected data are representative of this specific population, these biases do not pose an intractable validity problem if claims are properly restricted.\nThe size of many newly available datasets is one of their most appealing characteristics. Bigger datasets often make statistics more robust. The size needed for a computational text analysis depends on the research goal: When it involves studying rare events, bigger datasets are needed. However, larger is not always better. Some very large archives are “secretly” collections of multiple and distinct processes that no in-field scholar would consider related. For example, Google Books is frequently used to study cultural patterns, but the over-representation of scientific articles in Google books can be problematic BIBREF11 . Even very large born-digital datasets usually cover limited timespans compared to, e.g., the Gutenberg archive of British novels.\nThis stage of the research also raises important questions about fairness. Are marginalized groups, for example, represented in the tweets we have collected? If not, what types of biases might result from analyses relying on those tweets?\nLocal experts and “informants” can help navigate the data. They can help understand the role an archive plays in the time and place. They might tell us: Is this the central archive, or a peripheral one? What makes it unusual? Or they might tell us how certain underrepresented communities use a social media platform and advise us on strategies for ensuring our data collection includes their perspectives.\nHowever, when it is practically infeasible to navigate the data in this way—for instance, when we cannot determine what is missing from Twitter's Streaming API or what webpages are left out of the Internet Archive—we should be open about the limitations of our analyses, acknowledging the flaws in our data and drawing cautious and reasonable conclusions from them. In all cases, we should report the choices we have made when creating or re-using any dataset.\nFor instance, when using the Internet Archives Wayback Machine to gather data from archived web pages, we need to consider what pages were captured, which are likely missing, and why.",

The number of examples we collected increases per round, starting with approximately 19k examples for Round 1, to around 47k examples for Round 2, to over 103k examples for Round 3. We collected more data for later rounds not only because that data is likely to be more interesting, but also simply because the base model is better and so annotation took longer to collect good, verified correct examples of model vulnerabilities.\nFor each round, we report the model error rate, both on verified and unverified examples. The unverified model error rate captures the percentage of examples where the model disagreed with the writer's target label, but where we are not (yet) sure if the example is correct. The verified model error rate is the percentage of model errors from example pairs that other annotators were able to confirm the correct label for. Note that this error rate represents a straightforward way to evaluate model quality: the lower the model error rate—assuming constant annotator quality and context-difficulty—the better the model.\nWe observe that model error rates decrease as we progress through rounds. In Round 3, where we included a more diverse range of contexts from various domains, the overall error rate went slightly up compared to the preceding round, but for Wikipedia contexts the error rate decreased substantially. While for the first round roughly 1 in every 5 examples were verified model errors, this quickly dropped over consecutive rounds, and the overall model error rate is less than 1 in 10. On the one hand, this is impressive, and shows how far we have come with just three rounds. On the other hand, it shows that we still have a long way to go if even untrained annotators can fool ensembles of state-of-the-art models with relative ease.\nTable TABREF7 also reports the average number of “tries”, i.e., attempts made for each context until a model error was found (or the number of possible tries is exceeded), and the average time this took (in seconds). Again, these metrics represent a useful way to evaluate model quality. We observe that the average tries and average time per verified error both go up as we progress through the rounds. The numbers clearly demonstrate that the rounds are getting increasingly more difficult.\nThe number of examples we collected increases per round, starting with approximately 19k examples for Round 1, to around 47k examples for Round 2, to over 103k examples for Round 3.

Second, we will describe the annotation process. Finally, we will evaluate the agreement and draw some conclusions.\nGiven the theoretical background briefly introduced in section SECREF2 , we motivate our selection of the argumentation model by the following requirements. First, the scope of this work is to capture argumentation within a single document, thus focusing on micro-level models. Second, there should exist empirical evidence that such a model has been used for analyzing argumentation in previous works, so it is likely to be suitable for our purposes of argumentative discourse analysis in user-generated content. Regarding the first requirement, two typical examples of micro-level models are the Toulmin's model BIBREF36 and Walton's schemes BIBREF55 . Let us now elaborate on the second requirement.\nWalton's argumentation schemes are claimed to be general and domain independent. Nevertheless, evidence from the computational linguistics field shows that the schemes lack coverage for analyzing real argumentation in natural language texts. In examining real-world political argumentation from BIBREF56 , Walton.2012 found out that 37.1% of the arguments collected did not fit any of the fourteen schemes they chose so they created new schemes ad-hoc. Cabrio2013b selected five argumentation schemes from Walton and map these patterns to discourse relation categories in the Penn Discourse TreeBank (PDTB) BIBREF48 , but later they had to define two new argumentation schemes that they discovered in PDTB. Similarly, Song.et.al.2014 admitted that the schemes are ambiguous and hard to directly apply for annotation, therefore they modified the schemes and created new ones that matched the data.\nAlthough Macagno.Konstantinidou.2012 show several examples of two argumentation schemes applied to few selected arguments in classroom experiments, empirical evidence presented by Anthony.Kim.2014 reveals many practical and theoretical difficulties of annotating dialogues with schemes in classroom deliberation, providing many details on the arbitrary selection of the sub-set of the schemes, the ambiguity of the scheme definitions, concluding that the presence of the authors during the experiment was essential for inferring and identifying the argument schemes BIBREF57 .\nAlthough this model (refer to section SECREF21 ) was designed to be applicable to real-life argumentation, there are numerous studies criticizing both the clarity of the model definition and the differentiation between elements of the model. Ball1994 claims that the model can be used only for the most simple arguments and fails on the complex ones. Also Freeman1991 and other argumentation theorists criticize the usefulness of Toulmin's framework for the description of real-life argumentative texts. However, others have advocated the model and claimed that it can be applied to the people's ordinary argumenation BIBREF58 , BIBREF59 .\nA number of studies (outside the field of computational linguistics) used Toulmin's model as their backbone argumentation framework. Chambliss1995 experimented with analyzing 20 written documents in a classroom setting in order to find the argument patterns and parts. Simosi2003 examined employees' argumentation to resolve conflicts. Voss2006 analyzed experts' protocols dealing with problem-solving.\nThe model has also been used in research on computer-supported collaborative learning. Erduran2004 adapt Toulmin's model for coding classroom argumentative discourse among teachers and students. Stegmann2011 builds on a simplified Toulmin's model for scripted construction of argument in computer-supported collaborative learning. Garcia-Mila2013 coded utterances into categories from Toulmin's model in persuasion and consensus-reaching among students. Weinberger.Fischer.2006 analyze asynchronous discussion boards in which learners engage in an argumentative discourse with the goal to acquire knowledge. For coding the argument dimension, they created a set of argumentative moves based on Toulmin's model. Given this empirical evidence, we decided to build upon the Toulmin's model.\nIn this annotation task, a sequence of tokens (e.g. a phrase, a sentence, or any arbitrary text span) is labeled with a corresponding argument component (such as the claim, the grounds, and others). There are no explicit relations between these annotation spans as the relations are implicitly encoded in the pragmatic function of the components in the Toulmin's model.\nIn order to prove the suitability of the Toulmin's model, we analyzed 40 random documents from the gold data persuasive dataset using the original Toulmin's model as presented in section SECREF21 . We took into account sever criteria for assessment, such as frequency of occurrence of the components or their importance for the task. We proposed some modifications of the model based on the following observations.\nAuthors do not state the degree of cogency (the probability of their claim, as proposed by Toulmin). Thus we omitted qualifier from the model due to its absence in the data.\nThe warrant as a logical explanation why one should accept the claim given the evidence is almost never stated. As pointed out by BIBREF37 , “data are appealed to explicitly, warrants implicitly.” This observation has also been made by Voss2006. Also, according to [p. 205]Eemeren.et.al.1987, the distinction of warrant is perfectly clear only in Toulmin’s examples, but the definitions fail in practice. We omitted warrant from the model.\nRebuttal is a statement that attacks the claim, thus playing a role of an opposing view. In reality, the authors often attack the presented rebuttals by another counter-rebuttal in order to keep the whole argument's position consistent. Thus we introduced a new component – refutation – which is used for attacking the rebuttal. Annotation of refutation was conditioned of explicit presence of rebuttal and enforced by the annotation guidelines. The chain rebuttal–refutation is also known as the procatalepsis figure in rhetoric, in which the speaker raises an objection to his own argument and then immediately answers it. By doing so, the speaker hopes to strengthen the argument by dealing with possible counter-arguments before the audience can raise them BIBREF43 .\nThe claim of the argument should always reflect the main standpoint with respect to the discussed controversy. We observed that this standpoint is not always explicitly expressed, but remains implicit and must be inferred by the reader. Therefore, we allow the claim to be implicit. In such a case, the annotators must explicitly write down the (inferred) stance of the author.\nBy definition, the Toulmin's model is intended to model single argument, with the claim in its center. However, we observed in our data, that some authors elaborate on both sides of the controversy equally and put forward an argument for each side (by argument here we mean the claim and its premises, backings, etc.). Therefore we allow multiple arguments to be annotated in one document. At the same time, we restrained the annotators from creating complex argument hierarchies.\nToulmin's grounds have an equivalent role to a premise in the classical view on an argument BIBREF15 , BIBREF60 in terms that they offer the reasons why one should accept the standpoint expressed by the claim. As this terminology has been used in several related works in the argumentation mining field BIBREF7 , BIBREF61 , BIBREF62 , BIBREF11 , we will keep this convention and denote the grounds as premises.\nOne of the main critiques of the original Toulmin's model was the vague distinction between grounds, warrant, and backing BIBREF63 , BIBREF64 , BIBREF65 . The role of backing is to give additional support to the warrant, but there is no warrant in our model anymore. However, what we observed during the analysis, was a presence of some additional evidence. Such evidence does not play the role of the grounds (premises) as it is not meant as a reason supporting the claim, but it also does not explain the reasoning, thus is not a warrant either. It usually supports the whole argument and is stated by the author as a certain fact. Therefore, we extended the scope of backing as an additional support to the whole argument.\nThe annotators were instructed to distinguish between premises and backing, so that premises should cover generally applicable reasons for the claim, whereas backing is a single personal experience or statements that give credibility or attribute certain expertise to the author. As a sanity check, the argument should still make sense after removing backing (would be only considered “weaker”).\nWe call the model as a modified Toulmin's model. It contains five argument components, namely claim, premise, backing, rebuttal, and refutation. When annotating a document, any arbitrary token span can be labeled with an argument component; the components do not overlap. The spans are not known in advance and the annotator thus chooses the span and the component type at the same time. All components are optional (they do not have to be present in the argument) except the claim, which is either explicit or implicit (see above). If a token span is not labeled by any argument component, it is not considered as a part of the argument and is later denoted as none (this category is not assigned by the annotators).\nAn example analysis of a forum post is shown in Figure FIGREF65 . Figure FIGREF66 then shows a diagram of the analysis from that example (the content of the argument components was shortened or rephrased).\nThe annotation experiment was split into three phases. All documents were annotated by three independent annotators, who participated in two training sessions. During the first phase, 50 random comments and forum posts were annotated. Problematic cases were resolved after discussion and the guidelines were refined. In the second phase, we wanted to extend the range of annotated registers, so we selected 148 comments and forum posts as well as 41 blog posts. After the second phase, the annotation guidelines were final.\nIn the final phase, we extended the range of annotated registers and added newswire articles from the raw corpus in order to test whether the annotation guidelines (and inherently the model) is general enough. Therefore we selected 96 comments/forum posts, 8 blog posts, and 8 articles for this phase. A detailed inter-annotator agreement study on documents from this final phase will be reported in section UID75 .\nThe annotations were very time-consuming. In total, each annotator spent 35 hours by annotating in the course of five weeks. Discussions and consolidation of the gold data took another 6 hours. Comments and forum posts required on average of 4 minutes per document to annotate, while blog posts and articles on average of 14 minutes per document. Examples of annotated documents from the gold data are listed in Appendix UID158 .\nWe discarded 11 documents out of the total 351 annotated documents. Five forum posts, although annotated as persuasive in the first annotation study, were at a deeper look a mixture of two or more posts with missing quotations, therefore unsuitable for analyzing argumentation. Three blog posts and two articles were found not to be argumentative (the authors took no stance to the discussed controversy) and one article was an interview, which the current model cannot capture (a dialogical argumentation model would be required).\nFor each of the 340 documents, the gold standard annotations were obtained using the majority vote. If simple majority voting was not possible (different boundaries of the argument component together with a different component label), the gold standard was set after discussion among the annotators. We will refer to this corpus as the gold standard Toulmin corpus. The distribution of topics and registers in this corpus in shown in Table TABREF71 , and Table TABREF72 presents some lexical statistics.\nBased on pre-studies, we set the minimal unit for annotation as token. The documents were pre-segmented using the Stanford Core NLP sentence splitter BIBREF69 embedded in the DKPro Core framework BIBREF70 . Annotators were asked to stick to the sentence level by default and label entire pre-segmented sentences. They should switch to annotations on the token level only if (a) a particular sentence contained more than one argument component, or (b) if the automatic sentence segmentation was wrong. Given the “noise” in user-generated Web data (wrong or missing punctuation, casing, etc.), this was often the case.\nAnnotators were also asked to rephrase (summarize) each annotated argument component into a simple statement when applicable, as shown in Figure FIGREF66 . This was used as a first sanity checking step, as each argument component is expected to be a coherent discourse unit. For example, if a particular occurrence of a premise cannot be summarized/rephrased into one statement, this may require further splitting into two or more premises.\nFor the actual annotations, we developed a custom-made web-based application that allowed users to switch between different granularity of argument components (tokens or sentences), to annotate the same document in different argument “dimensions” (logos and pathos), and to write summary for each annotated argument component.\nAs a measure of annotation reliability, we rely on Krippendorff's unitized alpha ( INLINEFORM0 ) BIBREF71 . To the best of our knowledge, this is the only agreement measure that is applicable when both labels and boundaries of segments are to be annotated.\nAlthough the measure has been used in related annotation works BIBREF61 , BIBREF7 , BIBREF72 , there is one important detail that has not been properly communicated. The INLINEFORM0 is computed over a continuum of the smallest units, such as tokens. This continuum corresponds to a single document in the original Krippendorff's work. However, there are two possible extensions to multiple documents (a corpus), namely (a) to compute INLINEFORM1 for each document first and then report an average value, or (b) to concatenate all documents into one large continuum and compute INLINEFORM2 over it. The first approach with averaging yielded extremely high the standard deviation of INLINEFORM3 (i.e., avg. = 0.253; std. dev. = 0.886; median = 0.476 for the claim). This says that some documents are easy to annotate while others are harder, but interpretation of such averaged value has no evidence either in BIBREF71 or other papers based upon it. Thus we use the other methodology and treat the whole corpus as a single long continuum (which yields in the example of claim 0.541 INLINEFORM4 ).\nTable TABREF77 shows the inter-annotator agreement as measured on documents from the last annotation phase (see section UID67 ). The overall INLINEFORM0 for all register types, topics, and argument components is 0.48 in the logos dimension (annotated with the modified Toulmin's model). Such agreement can be considered as moderate by the measures proposed by Landis.Koch.1977, however, direct interpretation of the agreement value lacks consensus BIBREF54 . Similar inter-annotator agreement numbers were achieved in the relevant works in argumentation mining (refer to Table TABREF33 in section SECREF31 ; although most of the numbers are not directly comparable, as different inter-annotator metrics were used on different tasks).\nThere is a huge difference in INLINEFORM0 regarding the registers between comments + forums posts ( INLINEFORM1 0.60, Table TABREF77 a) and articles + blog posts ( INLINEFORM2 0.09, Table TABREF77 b) in the logos dimension. If we break down the value with respect to the individual argument components, the agreement on claim and premise is substantial in the case of comments and forum posts (0.59 and 0.69, respectively). By contrast, these argument components were annotated only with a fair agreement in articles and blog posts (0.22 and 0.24, respectively).\nAs can be also observed from Table TABREF77 , the annotation agreement in the logos dimension varies regarding the document topic. While it is substantial/moderate for prayer in schools (0.68) or private vs. public schools (0.44), for some topics it remains rather slight, such as in the case of redshirting (0.14) or mainstreaming (0.08).\nFirst, we examine the disagreement in annotations by posing the following research question: are there any measurable properties of the annotated documents that might systematically cause low inter-annotator agreement? We use Pearson's correlation coefficient between INLINEFORM0 on each document and the particular property under investigation. We investigated the following set of measures.\nFull sentence coverage ratio represents a ratio of argument component boundaries that are aligned to sentence boundaries. The value is 1.0 if all annotations in the particular document are aligned to sentences and 0.0 if no annotations match the sentence boundaries. Our hypothesis was that automatic segmentation to sentences was often incorrect, therefore annotators had to switch to the token level annotations and this might have increased disagreement on boundaries of the argument components.\nDocument length, paragraph length and average sentence length. Our hypotheses was that the length of documents, paragraphs, or sentences negatively affects the agreement.\nReadability measures. We tested four standard readability measures, namely Ari BIBREF73 , Coleman-Liau BIBREF74 , Flesch BIBREF75 , and Lix BIBREF76 to find out whether readability of the documents plays any role in annotation agreement.\nCorrelation results are listed in Table TABREF82 . We observed the following statistically significant ( INLINEFORM0 ) correlations. First, document length negatively correlates with agreement in comments. The longer the comment was the lower the agreement was. Second, average paragraph length negatively correlates with agreement in blog posts. The longer the paragraphs in blogs were, the lower agreement was reached. Third, all readability scores negatively correlate with agreement in the public vs. private school domain, meaning that the more complicated the text in terms of readability is, the lower agreement was reached. We observed no significant correlation in sentence coverage and average sentence length measures. We cannot draw any general conclusion from these results, but we can state that some registers and topics, given their properties, are more challenging to annotate than others.\nAnother qualitative analysis of disagreements between annotators was performed by constructing a probabilistic confusion matrix BIBREF77 on the token level. The biggest disagreements, as can be seen in Table TABREF85 , is caused by rebuttal and refutation confused with none (0.27 and 0.40, respectively). This is another sign that these two argument components were very hard to annotate. As shown in Table TABREF77 , the INLINEFORM5 was also low – 0.08 for rebuttal and 0.17 for refutation.\nWe analyzed the annotations and found the following phenomena that usually caused disagreements between annotators.\nEach argument component (e.g., premise or backing) should express one consistent and coherent piece of information, for example a single reason in case of the premise (see Section UID73 ). However, the decision whether a longer text should be kept as a single argument component or segmented into multiple components is subjective and highly text-specific.\nWhile rhetorical questions have been researched extensively in linguistics BIBREF78 , BIBREF79 , BIBREF80 , BIBREF81 , their role in argumentation represents a substantial research question BIBREF82 , BIBREF83 , BIBREF84 , BIBREF85 , BIBREF86 . Teninbaum.2011 provides a brief history of rhetorical questions in persuasion. In short, rhetorical questions should provoke the reader. From the perspective of our argumentation model, rhetorical questions might fall both into the logos dimension (and thus be labeled as, e.g., claim, premise, etc.) or into the pathos dimension (refer to Section SECREF20 ). Again, the decision is usually not clear-cut.\nAs introduced in section UID55 , rebuttal attacks the claim by presenting an opponent's view. In most cases, the rebuttal is again attacked by the author using refutation. From the pragmatic perspective, refutation thus supports the author's stance expressed by the claim. Therefore, it can be easily confused with premises, as the function of both is to provide support for the claim. Refutation thus only takes place if it is meant as a reaction to the rebuttal. It follows the discussed matter and contradicts it. Such a discourse is usually expressed as:\n[claim: My claim.] [rebuttal: On the other hand, some people claim XXX which makes my claim wrong.] [refutation: But this is not true, because of YYY.]\nHowever, the author might also take the following defensible approach to formulate the argument:\n[rebuttal: Some people claim XXX-1 which makes my claim wrong.] [refutation: But this is not true, because of YYY-1.] [rebuttal: Some people claim XXX-2 which makes my claim wrong.] [refutation: But this is not true, because of YYY-2.] [claim: Therefore my claim.]\nIf this argument is formulated without stating the rebuttals, it would be equivalent to the following:\n[premise: YYY-1.] [premise: YYY-2.] [claim: Therefore my claim.]\nThis example shows that rebuttal and refutation represent a rhetorical device to produce arguments, but the distinction between refutation and premise is context-dependent and on the functional level both premise and refutation have very similar role – to support the author's standpoint. Although introducing dialogical moves into monological model and its practical consequences, as described above, can be seen as a shortcoming of our model, this rhetoric figure has been identified by argumentation researchers as procatalepsis BIBREF43 . A broader view on incorporating opposing views (or lack thereof) is discussed under the term confirmation bias by BIBREF21 who claim that “[...] people are trying to convince others. They are typically looking for arguments and evidence to confirm their own claim, and ignoring negative arguments and evidence unless they anticipate having to rebut them.” The dialectical attack of possible counter-arguments may thus strengthen one's own argument.\nOne possible solution would be to refrain from capturing this phenomena completely and to simplify the model to claims and premises, for instance. However, the following example would then miss an important piece of information, as the last two clauses would be left un-annotated. At the same time, annotating the last clause as premise would be misleading, because it does not support the claim (in fact, it supports it only indirectly by attacking the rebuttal; this can be seen as a support is considered as an admissible extension of abstract argument graph by BIBREF87 ).\nDoc#422 (forumpost, homeschooling) [claim: I try not to be anti-homeschooling, but... it's just hard for me.] [premise: I really haven't met any homeschoolers who turned out quite right, including myself.] I apologize if what I'm saying offends any of you - that's not my intention, [rebuttal: I know that there are many homeschooled children who do just fine,] but [refutation: that hasn't been my experience.]\nTo the best of our knowledge, these context-dependent dialogical properties of argument components using Toulmin's model have not been solved in the literature on argumentation theory and we suggest that these observations should be taken into account in the future research in monological argumentation.\nAppeal to emotion, sarcasm, irony, or jokes are common in argumentation in user-generated Web content. We also observed documents in our data that were purely sarcastic (the pathos dimension), therefore logical analysis of the argument (the logos dimension) would make no sense. However, given the structure of such documents, some claims or premises might be also identified. Such an argument is a typical example of fallacious argumentation, which intentionally pretends to present a valid argument, but its persuasion is conveyed purely for example by appealing to emotions of the reader BIBREF88 .\nWe present some statistics of the annotated data that are important from the argumentation research perspective. Regardless of the register, 48% of claims are implicit. This means that the authors assume that their standpoint towards the discussed controversy can be inferred by the reader and give only reasons for that standpoint. Also, explicit claims are mainly written just once, only in 3% of the documents the claim was rephrased and occurred multiple times.\nIn 6% of the documents, the reasons for an implicit claim are given only in the pathos dimension, making the argument purely persuasive without logical argumentation.\nThe “myside bias”, defined as a bias against information supporting another side of an argument BIBREF89 , BIBREF90 , can be observed by the presence of rebuttals to the author's claim or by formulating arguments for both sides when the overall stance is neutral. While 85% of the documents do not consider any opposing side, only 8% documents present a rebuttal, which is then attacked by refutation in 4% of the documents. Multiple rebuttals and refutations were found in 3% of the documents. Only 4% of the documents were overall neutral and presented arguments for both sides, mainly in blog posts.\nWe were also interested whether mitigating linguistic devices are employed in the annotated arguments, namely in their main stance-taking components, the claims. Such devices typically include parenthetical verbs, syntactic constructions, token agreements, hedges, challenge questions, discourse markers, and tag questions, among others BIBREF91 . In particular, [p. 1]Kaltenbock.et.al.2010 define hedging as a discourse strategy that reduces the force or truth of an utterance and thus reduces the risk a speaker runs when uttering a strong or firm assertion or other speech act. We manually examined the use of hedging in the annotated claims.\nOur main observation is that hedging is used differently across topics. For instance, about 30-35% of claims in homeschooling and mainstreaming signal the lack of a full commitment to the expressed stance, in contrast to prayer in schools (15%) or public vs. private schools (about 10%). Typical hedging cues include speculations and modality (“If I have kids, I will probably homeschool them.”), statements as neutral observations (“It's not wrong to hold the opinion that in general it's better for kids to go to school than to be homeschooled.”), or weasel phrases BIBREF92 (“In some cases, inclusion can work fantastically well.”, “For the majority of the children in the school, mainstream would not have been a suitable placement.”).\nOn the other hand, most claims that are used for instance in the prayer in schools arguments are very direct, without trying to diminish its commitment to the conveyed belief (for example, “NO PRAYER IN SCHOOLS!... period.”, “Get it out of public schools”, “Pray at home.”, or “No organized prayers or services anywhere on public school board property - FOR ANYONE.”). Moreover, some claims are clearly offensive, persuading by direct imperative clauses towards the opponents/audience (“TAKE YOUR KIDS PRIVATE IF YOU CARE AS I DID”, “Run, don't walk, to the nearest private school.”) or even accuse the opponents for taking a certain stance (“You are a bad person if you send your children to private school.”).\nThese observations are consistent with the findings from the first annotation study on persuasion (see section UID48 ), namely that some topics attract heated argumentation where participant take very clear and reserved standpoints (such as prayer in schools or private vs. public schools), while discussions about other topics are rather milder. It has been shown that the choices a speaker makes to express a position are informed by their social and cultural background, as well as their ability to speak the language BIBREF93 , BIBREF94 , BIBREF91 . However, given the uncontrolled settings of the user-generated Web content, we cannot infer any similar conclusions in this respect.\nWe investigated premises across all topics in order to find the type of support used in the argument. We followed the approach of Park.Cardie.2014, who distinguished three types of propositions in their study, namely unverifiable, verifiable non-experiential, and verifiable experiential.\nVerifiable non-experiential and verifiable experiential propositions, unlike unverifiable propositions, contain an objective assertion, where objective means “expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations.” Such assertions have truth values that can be proved or disproved with objective evidence; the correctness of the assertion or the availability of the objective evidence does not matter BIBREF8 . A verifiable proposition can further be distinguished as experiential or not, depending on whether the proposition is about the writer's personal state or experience or something non-experiential. Verifiable experiential propositions are sometimes referred to as anectotal evidence, provide the novel knowledge that readers are seeking BIBREF8 .\nTable TABREF97 shows the distribution of the premise types with examples for each topic from the annotated corpus. As can be seen in the first row, arguments in prayer in schools contain majority (73%) of unverifiable premises. Closer examination reveals that their content vary from general vague propositions to obvious fallacies, such as a hasty generalization, straw men, or slippery slope. As Nieminen.Mustonen.2014 found out, fallacies are very common in argumentation about religion-related issues. On the other side of the spectrum, arguments about redshirting rely mostly on anecdotal evidence (61% of verifiable experiential propositions). We will discuss the phenomena of narratives in argumentation in more detail later in section UID98 . All the topics except private vs. public schools exhibit similar amount of verifiable non-experiential premises (9%–22%), usually referring to expert studies or facts. However, this type of premises has usually the lowest frequency.\nManually analyzing argumentative discourse and reconstructing (annotating) the underlying argument structure and its components is difficult. As [p. 267]Reed2006 point out, “the analysis of arguments is often hard, not only for students, but for experts too.” According to [p. 81]Harrell.2011b, argumentation is a skill and “even for simple arguments, untrained college students can identify the conclusion but without prompting are poor at both identifying the premises and how the premises support the conclusion.” [p. 81]Harrell.2011 further claims that “a wide literature supports the contention that the particular skills of understanding, evaluating, and producing arguments are generally poor in the population of people who have not had specific training and that specific training is what improves these skills.” Some studies, for example, show that students perform significantly better on reasoning tasks when they have learned to identify premises and conclusions BIBREF95 or have learned some standard argumentation norms BIBREF96 .\nOne particular extra challenge in analyzing argumentation in Web user-generated discourse is that the authors produce their texts probably without any existing argumentation theory or model in mind. We assume that argumentation or persuasion is inherent when users discuss controversial topics, but the true reasons why people participate in on-line communities and what drives their behavior is another research question BIBREF97 , BIBREF98 , BIBREF99 , BIBREF100 . When the analyzed texts have a clear intention to produce argumentative discourse, such as in argumentative essays BIBREF7 , the argumentation is much more explicit and a substantially higher inter-annotator agreement can be achieved.\nThe model seems to be suitable for short persuasive documents, such as comments and forum posts. Its applicability to longer documents, such as articles or blog posts, is problematic for several reasons.\nThe argument components of the (modified) Toulmin's model and their roles are not expressive enough to capture argumentation that not only conveys the logical structure (in terms of reasons put forward to support the claim), but also relies heavily on the rhetorical power. This involves various stylistic devices, pervading narratives, direct and indirect speech, or interviews. While in some cases the argument components are easily recognizable, the vast majority of the discourse in articles and blog posts does not correspond to any distinguishable argumentative function in the logos dimension. As the purpose of such discourse relates more to rhetoric than to argumentation, unambiguous analysis of such phenomena goes beyond capabilities of the current argumentation model. For a discussion about metaphors in Toulmin's model of argumentation see, e.g., BIBREF102 , BIBREF103 .\nArticles without a clear standpoint towards the discussed controversy cannot be easily annotated with the model either. Although the matter is viewed from both sides and there might be reasons presented for either of them, the overall persuasive intention is missing and fitting such data to the argumentation framework causes disagreements. One solution might be to break the document down to paragraphs and annotate each paragraph separately, examining argumentation on a different level of granularity.\nAs introduced in section SECREF20 , there are several dimensions of an argument. The Toulmin's model focuses solely on the logos dimension. We decided to ignore the ethos dimension, because dealing with the author's credibility remains unclear, given the variety of the source web data. However, exploiting the pathos dimension of an argument is prevalent in the web data, for example as an appeal to emotions. Therefore we experimented with annotating appeal to emotions as a separate category independent of components in the logos dimension. We defined some features for the annotators how to distinguish appeal to emotions. Figurative language such as hyperbole, sarcasm, or obvious exaggerating to “spice up” the argument are the typical signs of pathos. In an extreme case, the whole argument might be purely emotional, as in the following example.\nDoc#1698 (comment, prayer in schools) [app-to-emot: Prayer being removed from school is just the leading indicator of a nation that is ‘Falling Away’ from Jehovah. [...] And the disasters we see today are simply God’s finger writing on the wall: Mene, mene, Tekel, Upharsin; that is, God has weighed America in the balances, and we’ve been found wanting. No wonder 50 million babies have been aborted since 1973. [...]]\nWe kept annotations on the pathos dimension as simple as possible (with only one appeal to emotions label), but the resulting agreement was unsatisfying ( INLINEFORM0 0.30) even after several annotation iterations. Appeal to emotions is considered as a type of fallacy BIBREF104 , BIBREF18 . Given the results, we assume that more carefully designed approach to fallacy annotation should be applied. To the best of our knowledge, there have been very few research works on modeling fallacies similarly to arguments on the discourse level BIBREF105 . Therefore the question, in which detail and structure fallacies should be annotated, remains open. For the rest of the paper, we thus focus on the logos dimension solely.\nSome of the educational topics under examination relate to young children (e.g., redshirting or mainstreaming); therefore we assume that the majority of participants in discussions are their parents. We observed that many documents related to these topics contain narratives. Sometimes the story telling is meant as a support for the argument, but there are documents where the narrative has no intention to persuade and is simply a story sharing.\nThere is no widely accepted theory of the role of narratives among argumentation scholars. According to Fisher.1987, humans are storytellers by nature, and the “reason” in argumentation is therefore better understood in and through the narratives. He found that good reasons often take the form of narratives. Hoeken.Fikkers.2014 investigated how integration of explicit argumentative content into narratives influences issue-relevant thinking and concluded that identifying with the character being in favor of the issue yielded a more positive attitude toward the issue. In a recent research, Bex.2011 proposes an argumentative-narrative model of reasoning with evidence, further elaborated in BIBREF106 ; also Niehaus.et.al.2012 proposes a computational model of narrative persuasion.\nStemming from another research field, LeytonEscobar2014 found that online community members who use and share narratives have higher participation levels and that narratives are useful tools to build cohesive cultures and increase participation. Betsch.et.al.2010 examined influencing vaccine intentions among parents and found that narratives carry more weight than statistics.\nAs a measure of annotation reliability, we rely on Krippendorff’s unitized alpha (αU) (Krippendorff 2004).",

        "evidence": "Charles Henry Bromedge Caldwell was born in Hingham, Massachusetts on February 24, 1823. He entered the navy as midshipman February 27, 1838, and became lieutenant September 4, 1852. He commanded the USS Vandalia in the US Navy's second Fiji expedition, an 1859 punitive expedition against Waya Island warriors who had cannibalized two American traders. In 1862, he commanded the gun-boat Itasca, of the western gulf blockading squadron, and took part in the bombardment of Forts Jackson and St. Philip. On the night of April 20, his gun-boat, with the Pinola, was sent on an expedition under the command of Fleet-Capt. Bell, to make a passage for the fleet through the chain obstructions near the forts. Lieut. Caldwell and his party boarded one of the hulks that held the chains, and succeeded in detaching the latter, in spite of the heavy fire to which they were subjected.

        "question": "On what tasks do they compare their model with baselines?",
        "answer": "Generative model evaluation (i.e. test set perplexity) and document classification.",
        "evidence": "Statistic topic models such as Latent Dirichlet Allocation (LDA) and its variants BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 have been proven to be effective in modeling textual documents. In these models, a word token in a document is assumed to be generated by a hidden mixture model, where the hidden variables are the topic indexes for each word and the topic assignments for words are related to document level topic weights. Due to the effectiveness and efficiency in modeling the document generation process, topic models are widely adopted in quite a lot of real world tasks such as sentiment classification BIBREF5 , social network analysis BIBREF6 , BIBREF5 , and recommendation systems BIBREF7 .\nMost topic models take the bag-of-words assumption, in which every document is treated as an unordered set of words and the word tokens in such a document are sampled independently with each other. The bag-of-words assumption brings computational convenience, however, it sacrifices the characterization of sequential properties of words in a document and the topic coherence between words belonging to the same language segment (e.g., sentence). As a result, people have observed many negative examples. Just list one for illustration BIBREF8 : the department chair couches offers and the chair department offers couches have very different topics, although they have exactly the same bag of words.\nThere have been some works trying to solve the aforementioned problems, although still insufficiently. For example, several sentence level topic models BIBREF9 , BIBREF10 , BIBREF11 tackle the topic coherence problem by assuming all the words in a sentence to share the same topic (i.e., every sentence has only one topic). In addition, they model the sequential information by assuming the transition between sentence topics to be Markovian. However, words within the same sentence are still exchangeable in these models, and thus the bag-of-words assumption still holds within a sentence. For another example, in BIBREF12 , the embedding based neural language model BIBREF13 , BIBREF14 , BIBREF15 and topic model are integrated. They assume the generation of a given word in a sentence to depend on its local context (including its preceding words within a fixed window) as well as the topics of the sentence and document it lies in. However, using a fixed window of preceding words, instead of the whole word stream within a sentence, could only introduce limited sequential dependency. Furthermore, there is no explicit coherence constraints on the word topics and sentence topics, since every word can have its own topics in their model.\nWe propose Sentence Level Recurrent Topic Model (SLRTM) to tackle the limitations of the aforementioned works. In the new model, we assume the words in the same sentence to share the same topic in order to guarantee topic coherence, and we assume the generation of a word to rely on the whole history in the same sentence in order to fully characterize the sequential dependency. Specifically, for a particular word INLINEFORM0 within a sentence INLINEFORM1 , we assume its generation depends on two factors: the first is the whole set of its historical words in the sentence and the second is the sentence topic, which we regard as a pseudo word and has its own distributed representations. We use Recurrent Neural Network (RNN) BIBREF16 , such as Long Short Term Memory (LSTM) BIBREF17 or Gated Recurrent Unit (GRU) network BIBREF18 , to model such a long term dependency.\nWith the proposed SLRTM, we can not only model the document generation process more accurately, but also construct new natural sentences that are coherent with a given topic (we call it topic2sentence, similar to image2sentece BIBREF19 ). Topic2sentence has its huge potential for many real world tasks. For example, it can serve as the basis of personalized short text conversation system BIBREF20 , BIBREF21 , in which once we detect that the user is interested in certain topics, we can let these topics speak for themselves using SLRTM to improve the user satisfactory.\nWe have conducted experiments to compare SLRTM with several strong topic model baselines on two tasks: generative model evaluation (i.e. test set perplexity) and document classification. The results on several benchmark datasets quantitatively demonstrate SLRTM's advantages in modeling documents. We further provide some qualitative results on topic2sentence, the generated sentences for different topics clearly demonstrate the power of SLRTM in topic-sensitive short text conversations.\nWe have conducted experiments to compare SLRTM with several strong topic model baselines on two tasks: generative model evaluation (i.e. test set perplexity) and document classification.",

Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference (XNL) (Conneau et al., 2018) and universal dependency parsing.

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nOur BAE attack beats the previous baselines by a large margin on empirical evaluation over multiple datasets and models.",

We report results where BLSTM with attention is used as the DNN model. Results for other models are similar BIBREF15 .

TL1 resulted in significantly low recall indicating that three datasets have different nature of cyberbullying with low overlap (Table TABREF25 ). However precision was relatively higher for TL1, indicating that DNN models are cautious in labeling a post as bully (Table TABREF25 ). TL1 also helps to measure similarity in nature of cyberbullying across three datasets. We can observe that bullying nature in Formspring and Wikipedia datasets is more similar to each other than the Twitter dataset. This can be inferred from the fact that with TL1, cyberbullying detection performance for Formspring dataset is higher when base model is Wikipedia (precision =0.51 and recall=0.66)as compared to Twitter as the base model (precision=0.38 and recall=0.04). Similarly, for Wikipedia dataset, Formspring acts as a better base model than Twitter while using TL1 flavor of transfer learning.

        "evidence": "Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy. This difference in mass arises due to the difference in nuclear binding energy between the atomic nuclei before and after the reaction. Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released.\n\nA nuclear fusion process that produces atomic nuclei lighter than iron-56 or nickel-62 will generally release energy. These elements have a relatively small mass and a relatively large binding energy per nucleon. Fusion of nuclei lighter than these releases energy (an exothermic process), while the fusion of heavier nuclei results in energy retained by the product nucleons, and the resulting reaction is endothermic. The opposite is true for the reverse process, called nuclear fission. Nuclear fusion uses lighter elements, such as hydrogen and helium, which are in general more fusible; while the heavier elements, such as uranium, thorium and plutonium, are more fissionable. The extreme astrophysical event of a supernova can produce enough energy to fuse nuclei into elements heavier than iron.",

        "answer": "Aerial drones are a great way to gain a unique perspective and view of the world we live in.  As a recreational drone pilot you can capture and immortalize the incredible views experienced in nature while engaging in many outdoor activities. Many also engage in racing and building highly customized high speed drones using first person view (FPV) goggles to fly against other pilots in a close loop course. Before engaging in this fun and rewarding activity there are many rules that a drone pilot must be aware of in order to safely and legally operate your drone. These rules do not apply to racing drones in sanctioned races but do apply to all drones flown in public airspace.  All drones over 0.55lbs or 250g need to be registered through the FAA website and can not weigh over 55lbs.  If you plan to fly your drone over highly populated areas such as towns, sporting events, or concerts you will need to check local rules and ordinances that require special local licensing, insurance, or approvals.  Many higher end drones come with automated software that provides a geospatial mapping software in their interface that lets you know if you are flying in any restricted areas.  These include airports, helipads, government facilities, wildlife sanctuaries, etc.  All hobbyist drone pilots must follow two main rules.  You can never fly above 400 feet and regardless of range you must keep the drone within line of sight.  You are completely responsible for any damage your drone causes in the event of loss of control that results in a crash.  Lastly, use common sense and don’t invade others' personal space or to invade others’ personal privacy.  Staying within these guidelines can provide a joyful and rewarding experience for those who both fly and view the content produced by this hobby and will ensure our ability to do so into the future.",

EQREF5 by INLINEFORM0 , where INLINEFORM1 is a transformation that may depend both on the scores INLINEFORM2 and on upper bounds INLINEFORM3 that limit the amount of attention that each word can receive.

        "question": "What is \"Fused Bifocal Attention Mechanism\"?",
        "answer": "It is a mechanism that imitates the way human completes writing a description of paired information.",
        "evidence": "Intuitively, when a human writes a description from a table she keeps track of information at two levels. At the macro level, it is important to decide which is the appropriate field to attend to next and at a micro level (i.e., within a field) it is important to know which values to attend to next. To capture this behavior, we use a bifocal attention mechanism as described below.\nMacro Attention: Consider the INLINEFORM0 -th field INLINEFORM1 which has values INLINEFORM2 . Let INLINEFORM3 be the representation of this field in the infobox. This representation can either be (i) the word embedding of the field name or (ii) some function INLINEFORM4 of the values in the field or (iii) a concatenation of (i) and (ii). The function INLINEFORM5 could simply be the sum or average of the embeddings of the values in the field. Alternately, this function could be a GRU (or LSTM) which treats these values within a field as a sequence and computes the field representation as the final representation of this sequence (i.e., the representation of the last time-step). We found that bidirectional GRU is a better choice for INLINEFORM6 and concatenating the embedding of the field name with this GRU representation works best. Further, using a bidirectional GRU cell to take contextual information from neighboring fields also helps (these are the orange colored cells in the top-left block in Figure FIGREF3 with macro attention). Given these representations INLINEFORM7 for all the INLINEFORM8 fields we compute an attention over the fields (macro level). DISPLAYFORM0 \nwhere INLINEFORM0 is the state of the decoder at time step INLINEFORM1 . INLINEFORM2 and INLINEFORM3 are parameters, INLINEFORM4 is the total number of fields in the input, INLINEFORM5 is the macro (field level) context vector at the INLINEFORM6 -th time step of the decoder.\nMicro Attention: Let INLINEFORM0 be the representation of the INLINEFORM1 -th value in a given field. This representation could again either be (i) simply the embedding of this value (ii) or a contextual representation computed using a function INLINEFORM2 which also considers the other values in the field. For example, if INLINEFORM3 are the values in a field then these values can be treated as a sequence and the representation of the INLINEFORM4 -th value can be computed using a bidirectional GRU over this sequence. Once again, we found that using a bi-GRU works better then simply using the embedding of the value. Once we have such a representation computed for all values across all the fields, we compute the attention over these values (micro level) as shown below : DISPLAYFORM0 \n where INLINEFORM0 is the state of the decoder at time step INLINEFORM1 . INLINEFORM2 and INLINEFORM3 are parameters, INLINEFORM4 is the total number of values across all the fields.\nFused Attention: Intuitively, the attention weights assigned to a field should have an influence on all the values belonging to the particular field. To ensure this, we reweigh the micro level attention weights based on the corresponding macro level attention weights. In other words, we fuse the attention weights at the two levels as: DISPLAYFORM0 \n where INLINEFORM0 is the field corresponding to the INLINEFORM1 -th value, INLINEFORM2 is the macro level context vector.\nIntuitively, when a human writes a description from a table she keeps track of information at two levels. At the macro level, it is important to decide which is the appropriate field to attend to next and at a micro level (i.e., within a field) it is important to know which values to attend to next.

A language is not only a way to communicate, it transmits also tradition, culture, emotions, mindset and many other habits that are typical in a specific country. Parents should not mix languages as children need to learn that a specific person has to be addressed in a specific language, otherwise they learn that languages can be mixed. The passive skills are always bigger than the active language skills, don't give up too early! They will make use of their passive language skills at some point. It is easier to learn languages if you also listen to music, watch movies in different languages and have friends that speak those languages. Remember that every person is different. Even if you raise different kids the same way, some of them might learn languages easier than others.

Pocket Pikachu was released in Japan in March 1998, with the first ever Pokémon film, Pokémon: The First Movie, first released in Japan in July 1998.\n\nIn 1998, Nintendo spent $25 million promoting Pokémon in the United States in partnership with Hasbro, KFC, and others. Nintendo initially feared that Pokémon was too Japanese for Western tastes but Alfred Kahn, then CEO of 4Kids Entertainment, convinced the company otherwise. The one who spotted Pokémon's potential in the United States was Kahn's colleague Thomas Kenney.\n\nIn November 2005, 4Kids Entertainment, which had managed the non-game related licensing of Pokémon, announced that it had agreed not to renew the Pokémon representation agreement. The Pokémon Company International oversees all Pokémon licensing outside Asia. In 2006, the franchise celebrated its tenth anniversary with the release of Pokémon Diamond and Pearl.

        "answer": "They investigate the ability of neural networks (LSTMs) to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves (ROC curves).",
        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nThus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves.",

        "answer": "Yes.",
        "evidence": "Sarcasm, a creative device used to communicate an intended meaning that is actually the opposite of its literal meaning, is notoriously difficult to convey and interpret through text, in part because doing so relies heavily upon shared contextual understandings that can be marked more easily by altered prosody (e.g., emphasis upon certain words) or non-verbal signals (e.g., rolling one's eyes). It is a complex process even for humans, and in fact an inability to detect sarcasm has been linked with a number of neurocognitive disorders, including dementia BIBREF0 . It is similarly a challenging open task in natural language processing, and has direct implications to a number of other critical application areas, such as sentiment analysis.\nMost research on automatic sarcasm detection to date has focused on the Twitter domain, which boasts an ample source of publicly-available data, some of which is already self-labeled by users for the presence of sarcasm (e.g., with #sarcasm). However, Twitter is highly informal, space-restricted, and subject to frequent topic fluctuations from one post to the next due to the ebb and flow of current events—in short, it is not broadly representative of most text domains. Thus, sarcasm detectors trained using features designed for maximum Twitter performance are not necessarily transferable to other domains. Despite this, it is desirable to develop approaches that can harness the more generalizable information present in the abundance of Twitter data.\nIn this work, we develop a set of domain-independent features for sarcasm detection and show that the features generally perform well across text domains. Further, we validate that domain adaptation can be applied to sarcasm detection to leverage patterns in out-of-domain training data, even when results from training only on that source domain data are extremely bad (far below baseline results), to improve over training on only the target data or over training on the simply combined dataset. Finally, we make a new dataset of sarcastic and non-sarcastic tweets available online as a resource to other researchers.\nFurther, we validate that domain adaptation can be applied to sarcasm detection to leverage patterns in out-of-domain training data, even when results from training only on that source domain data are extremely bad (far below baseline results), to improve over training on only the target data or over training on the simply combined dataset.",

Canada's capital is Ottawa and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.\n\nIndigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster, 1931, and culminating in the Canada Act 1982, which severed the vestiges of legal dependence on the Parliament of the United Kingdom.\n\nCanada is a parliamentary liberal democracy and a constitutional monarchy in the Westminster tradition. The country's head of government is the prime minister, who holds office by virtue of their ability to command the confidence of the elected House of Commons and is \"called upon\" by the governor general, representing the monarch of Canada, the head of state.

        "answer": "To generate examples that can fool or increase the probability of misclassification in text classifiers.",
        "evidence": "Adversarial examples are generally minimal perturbations applied to the input data in an effort to expose the regions of the input space where a trained model performs poorly. Prior works BIBREF0, BIBREF1 have demonstrated the ability of an adversary to evade state-of-the-art classifiers by carefully crafting attack examples which can be even imperceptible to humans. Following such approaches, there has been a number of techniques aimed at generating adversarial examples BIBREF2, BIBREF3. Depending on the degree of access to the target model, an adversary may operate in one of the two different settings: (a) black-box setting, where an adversary doesn't have access to target model's internal architecture or its parameters, (b) white-box setting, where an adversary has access to the target model, its parameters, and input feature representations. In both these settings, the adversary cannot alter the training data or the target model itself. Depending on the purpose of the adversary, adversarial attacks can be categorized as (a) targeted attack and (b) non-targeted attack. In a targeted attack, the output category of a generated example is intentionally controlled to a specific target category with limited change in semantic information. While a non-targeted attack doesn't care about the category of misclassified results.\nMost of the prior work has focused on image classification models where adversarial examples are obtained by introducing imperceptible changes to pixel values through optimization techniques BIBREF4, BIBREF5. However, generating natural language adversarial examples can be challenging mainly due to the discrete nature of text samples. Continuous data like image or speech is much more tolerant to perturbations compared to text BIBREF6. In textual domain, even a small perturbation is clearly perceptible and can completely change the semantics of the text. Another challenge for generating adversarial examples relates to identifying salient areas of the text where a perturbation can be applied successfully to fool the target classifier. In addition to fooling the target classifier, the adversary is designed with different constraints depending on the task and its motivations BIBREF7. In our work, we focus on constraining our adversary to craft examples with semantic preservation and minimum perturbations to the input text.\nGiven different settings of the adversary, there are other works that have designed attacks in “gray-box” settings BIBREF8, BIBREF9, BIBREF10. However, the definitions of “gray-box” attacks are quite different in each of these approaches. In this paper, we focus on “black-box” setting where we assume that the adversary possesses a limited set of labeled data, which is different from the target's training data, and also has an oracle access to the system, i.e., one can query the target classifier with any input and get its corresponding predictions. We propose an effective technique to generate adversarial examples in a black-box setting. We develop an Adversarial Example Generator (AEG) model that uses a reinforcement learning framing to generate adversarial examples. We evaluate our models using a word-based BIBREF11 and character-based BIBREF12 text classification model on benchmark classification tasks: sentiment classification and news categorization. The adversarial sequences generated are able to effectively fool the classifiers without changing the semantics of the text. Our contributions are as follows:\nWe propose a black-box non-targeted attack strategy by combining ideas of substitute network and adversarial example generation. We formulate it as a reinforcement learning task.\nWe introduce an encoder-decoder that operates over words and characters of an input text and empowers the model to introduce word and character-level perturbations.\nWe adopt a self-critical sequence training technique to train our model to generate examples that can fool or increase the probability of misclassification in text classifiers.\nWe evaluate our models on two different datasets associated with two different tasks: IMDB sentiment classification and AG's news categorization task. We run ablation studies on various components of the model and provide insights into decisions of our model.\nWe adopt a self-critical sequence training technique to train our model to generate examples that can fool or increase the probability of misclassification in text classifiers.",

        "evidence": "There is one globally recognized approach for defining and measuring hunger generally used by those studying or working to relieve hunger as a social problem. This is the United Nation's FAO measurement, which is typically referred to as chronic undernourishment (or in older publications, as 'food deprivation,' 'chronic hunger,' or just plain 'hunger.') For the FAO:\n\nHunger or chronic undernourishment exists when \"caloric intake is below the minimum dietary energy requirement (MDER). The MDER is the amount of energy needed to perform light activity and to maintain a minimum acceptable weight for attained height.\" The FAO use different MDER thresholds for different countries, due to variations in climate and cultural factors. Typically a yearly \"balance sheet\" approach is used, with the minimum dietary energy requirement tallied against the estimated total calories consumed over the year. The FAO definitions differentiate hunger from malnutrition and food insecurity:\nMalnutrition results from \"deficiencies, excesses or imbalances in the consumption of macro- and/or micro-nutrients.\" In the FAO definition, all hungry people suffer from malnutrition, but people who are malnourished may not be hungry. They may get sufficient raw calories to avoid hunger but lack essential micronutrients, or they may even consume an excess of raw calories and hence suffer from obesity.\nFood insecurity occurs when people are at risk, or worried about, not being able to meet their preferences for food, including in terms of raw calories and nutritional value. In the FAO definition, all hungry people are food insecure, but not all food-insecure people are hungry (though there is a very strong overlap between hunger and severe food insecurity.). The FAO have reported that food insecurity quite often results in simultaneous stunted growth for children, and obesity for adults. For hunger relief actors operating at the global or regional level, an increasingly commonly used metric for food insecurity is the IPC scale.\nAcute hunger is typically used to denote famine like hunger, though the phrase lacks a widely accepted formal definition. In the context of hunger relief, people experiencing 'acute hunger' may also suffer from 'chronic hunger'. The word is used mainly to denote severity, not long-term duration.\nNot all of the organizations in the hunger relief field use the FAO definition of hunger. Some use a broader definition that overlaps more fully with malnutrition. The alternative definitions do however tend to go beyond the commonly understood meaning of hunger as a painful or uncomfortable motivational condition; the desire for food is something that all humans frequently experience, even the most affluent, and is not in itself a social problem.\n\nVery low food supply can be described as \"food insecure with hunger.\" A change in description was made in 2006 at the recommendation of the Committee on National Statistics (National Research Council, 2006) in order to distinguish the physiological state of hunger from indicators of food availability. Food insecure is when food intake of one or more household members was reduced and their eating patterns were disrupted at times during the year because the household lacked money and other resources for food. Food security statistics is measured by using survey data, based on household responses to items about whether the household was able to obtain enough food to meet their needs.",

        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nIn order to capture the local context, we are the first to apply LSTM-minus to text summarization.",

Wang et al. (2017) and Huang, Qian, and Zhu (2017) proposed models based on a tree-LSTM which also uses the tag vectors to control the gate functions of the tree-LSTM.",
        "evidence": "Recursive neural networks (RvNN) are a kind of neural architecture which model sentences by exploiting syntactic structure. While earlier RvNN models proposed utilizing diverse composition functions, including feed-forward neural networks BIBREF12 , matrix-vector multiplication BIBREF5 , and tensor computation BIBREF6 , tree-LSTMs BIBREF13 remain the standard for several sentence-level tasks.\nEven though classic RvNNs have demonstrated superior performance on a variety of tasks, their inflexibility, i.e. their inability to handle dynamic compositionality for different syntactic configurations, is a considerable weakness. For instance, it would be desirable if our model could distinguish e.g. adjective-noun composition from that of verb-noun or preposition-noun composition, as models failing to make such a distinction ignore real-world syntactic considerations such as `-arity' of function words (i.e. types), and the adjunct/argument distinction.\nTo enable dynamic compositionality in recursive neural networks, many previous works BIBREF14 , BIBREF15 , BIBREF16 , BIBREF9 , BIBREF17 , BIBREF18 , BIBREF19 have proposed various methods.\nOne main direction of research leverages tag information, which is produced as a by-product of parsing. In detail, BIBREF16 ( BIBREF16 ) suggested TG-RNN, a model employing different composition functions according to POS tags, and TE-RNN/TE-RNTN, models which leverage tag embeddings as additional inputs for the existing tree-structured models. Despite the novelty of utilizing tag information, the explosion of the number of parameters (in case of the TG-RNN) and the limited performance of the original models (in case of the TE-RNN/TE-RNTN) have prevented these models from being widely adopted. Meanwhile, BIBREF9 ( BIBREF9 ) and BIBREF18 ( BIBREF18 ) proposed models based on a tree-LSTM which also uses the tag vectors to control the gate functions of the tree-LSTM. In spite of their impressive results, there is a limitation that the trained tag embeddings are too simple to reflect the rich information which tags provide in different syntactic structures. To alleviate this problem, we introduce structure-aware tag representations in the next section.\nAnother way of building dynamic compositionality into RvNNs is to take advantage of a meta-network (or hyper-network). Inspired by recent works on dynamic parameter prediction, DC-TreeLSTMs BIBREF17 dynamically create the parameters for compositional functions in a tree-LSTM. Specifically, the model has two separate tree-LSTM networks whose architectures are similar, but the smaller of the two is utilized to calculate the weights of the bigger one. A possible problem for this model is that it may be easy to be trained such that the role of each tree-LSTM is ambiguous, as they share the same input, i.e. word information. Therefore, we design two disentangled tree-LSTMs in our model so that one focuses on extracting useful features from only syntactic information while the other composes semantic units with the aid of the features. Furthermore, our model reduces the complexity of computation by utilizing typical tree-LSTM frameworks instead of computing the weights for each example.\nFinally, some recent works BIBREF10 , BIBREF11 have proposed latent tree-structured models that learn how to formulate tree structures from only sequences of tokens, without the aid of syntactic trees or linguistic information. The latent tree models have the advantage of being able to find the optimized task-specific order of composition rather than a sequential or syntactic one. In experiments, we compare our model with not only syntactic tree-based models but also latent tree models, demonstrating that modeling with explicit linguistic knowledge can be an attractive option.\nQian et al. (2015) suggested TG-RNN, a model employing different composition functions according to POS tags, and TERNN/TE-RNTN, models which leverage tag embeddings as additional inputs for the existing tree-structured models. Wang et al. (2017) and Huang, Qian, and Zhu (2017) proposed models based on a tree-LSTM which also uses the tag vectors to control the gate functions of the tree-LSTM.",

The state representation is text only encoded using recurrent networks.\nA2C-chained Is a variation on KG-A2C-chained where we use our policy chaining approach with the A2C method to train the agent instead of KG-A2C.\nA2C-Explore Uses A2C in addition to the exploration strategy seen in KG-A2C-Explore. The cell representations here are defined in terms of the recurrent network based encoding of the textual observation.\nFigure FIGREF10 shows that agents utilizing knowledge-graphs in addition to either enhanced exploration method far outperform the baseline A2C and KG-A2C. KG-A2C-chained and KG-A2C-Explore both pass the bottleneck of a score of 40, whereas A2C-Explore gets to the bottleneck but cannot surpass it.\nThere are a couple of key insights that can be drawn from these results The first is that the knowledge graph appears to be critical; it is theorized to help with partial observability. However the knowledge graph representation isn't sufficient in that the knowledge graph representation without enhanced exploration methods cannot surpass the bottleneck. A2C-chained—which explores without a knowledge graph—fails to even outperform the baseline A2C. We hypothesize that this is due to the knowledge graph aiding implicitly in the sample efficiency of bottleneck detection and subsequent exploration. That is, exploring after backtracking from a potentially detected bottleneck is much more efficient in the knowledge graph based agent.\nThe Go-Explore based exploration algorithm sees less of a difference between agents. A2C-Explore converges more quickly, but to a lower reward trajectory that fails to pass the bottleneck, whereas KG-A2C-Explore takes longer to reach a similar reward but consistently makes it through the bottleneck. The knowledge graph cell representation appears to thus be a better indication of what a promising state is as opposed to just the textual observation.\nComparing the advanced exploration methods when using the knowledge graph, we see that both agents successfully pass the bottleneck corresponding to entering the cellar and lighting the lamp and reach comparable scores within a margin of error. KG-A2C-chained is significantly more sample efficient and converges faster. We can infer that chaining policies by explicitly detecting bottlenecks lets us pass it more quickly than attempting to find promising cell representations with Go-Explore. This form of chained exploration with backtracking is particularly suited to sequential decision making problems that can be represented as acyclic directed graphs as in Figure FIGREF1.\nWe compare our two exploration strategies to the following baselines and ablations: • KG-A2C This is the exact same method presented in Ammanabrolu & Hausknecht (2020) with no modifications. • A2C Represents the same approach as KG-A2C but with all the knowledge graph components removed.

        "question": "What are the resulting features of the common Bi-LSTM?",
        "answer": "the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nThus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.",

        "question": "Under what license the multilingual WordNet can be available?",
        "answer": "An open (CC-BY) license.",
        "evidence": "Princeton WordNet BIBREF0 is one of the most important resources used in many different tasks across linguistics and natural language processing, however the resource is only available for English and is limited in its coverage of real world concepts. To cross the language barrier, huge efforts have been made to extend the Princeton WordNet with multilingual information in projects, such as EuroWordNet BIBREF1 , BalkaNet BIBREF2 and MultiWordNet BIBREF3 , mostly following the extend approach, where the structure of the Princeton WordNet is preserved and only the words in each synset are translated and new synsets are added for concepts. Furthermore, the Princeton WordNet has many fewer concepts than large scale encyclopedias such as Wikipedia and resources derived from it such as DBpedia BIBREF4 and BabelNet BIBREF5 . This problem is even worse for many non-English wordnets, due to the extend approach, as these resources have even fewer synsets than Princeton WordNet. Furthermore, there are still many languages for which a wordnet does not exist or is not available to all potential users due to licensing restrictions.\nTo address these deficiencies we propose two approaches. Firstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages. While an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries. In addition, our method can handle fundamental complexities such as the need to translate all senses of a word including low-frequency senses, which is very challenging for current SMT approaches. For these reasons, we leverage existing translations of Princeton WordNet entries in other languages to identify contextual information for wordnet senses from a large set of generic parallel corpora. The goal is to identify sentences that share the same semantic information in respect to the synset of the Princeton WordNet entry that we want to translate. Secondly, we describe a novel system based on state-of-the-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia. This method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks. These statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph. These are combined using a constraint-based solver that considers not only the semantic similarity of the synsets but also the overall structure of the alignment and its consistency, following the best practices in ontology alignment.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet BIBREF6 , which is available under an open (CC-BY) license. Finally, we describe how this resource is published, firstly as linked data in the linguistic linked open data cloud, as well as published in all the formats of the Global WordNet Association Interlingual Index.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet [7], which is available under an open (CC-BY) license",

        "evidence": "Table TABREF14 presents results for all models across the four variations of the dataset. First, BERT is consistently the best approach for in-scope, followed by MLP. Second, out-of-scope query performance is much lower than in-scope across all methods. Training on less data (Small and Imbalanced) yields models that perform slightly worse on in-scope queries. The trend is mostly the opposite when evaluating out-of-scope, where recall increases under the Small and Imbalanced training conditions. Under these two conditions, the size of the in-scope training set was decreased, while the number of out-of-scope training queries remained constant. This indicates that out-of-scope performance can be increased by increasing the relative number of out-of-scope training queries. We do just that in the OOS+ setting—where the models were trained on the full training set as well as 150 additional out-of-scope queries—and see that performance on out-of-scope increases substantially, yet still remains low relative to in-scope accuracy.\nFirst, BERT is consistently the best approach for in-scope, followed by MLP.",

        "answer": "They are precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10).",
        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nWe assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) (Jarvelin and Kek ¨ al¨ ainen ¨ , 2002).",

The base model sixth-generation Outback was offered with the 2.5-liter gasoline direct-injection FB25D; a turbocharged 2.4-liter FA24F that was first used on the Subaru Ascent was offered as the uplevel engine, providing improved power, torque, and consumption compared to the discontinued EZ36.\n\nIn addition to all-wheel drive coming standard on every trim, the 2021 model year also added LED adaptive steering-responsive headlights (SRH) on premium variants and a seat-belt reminder standard for all passengers.\n\nWorld markets outside of North America, including Japan, did not launch the sixth generation Outback until 2021.\n\nAustralia launched on the 20th February 2021 with a number of differences over the North American version including updated LED headlights with combined Day Running Light and turn/direction indicator with SRH (Steering Responsive Headlights) standard across all variants (the Touring model also gained Adaptive Driving Beam (ADB) until 2023 when ADB became standard across all model variants), as is pushbutton-start with tailgate PIN access. There is improved camera resolution for rear, side and front driver assistance cameras, EyeSight 4.0 with roadside speed sign reading, adjustable speed limiting, and intersection crash avoidance utilising new EyeSight cameras with a wider field of view and a lower profile inside the cabin. Subaru claim the sole engine fitted to Australian Outbacks, the revised 2.5-litre FB25D, is made of 90% new components compared to the Gen5 engine as well. The Japanese Outback was announced on October 7, 2021; in Japan the Outback is offered exclusively with the 1.8-litre CB18 gasoline direct-injection turbo engine instead.\n\nIn September 2021, the European variant received a five-star rating by the European New Car Assessment Programme (EuroNCAP) 2021.\n\nFor the 2022 model year, Subaru added a new trim level, the Wilderness. Outback Wilderness features 9.5 inches of ground clearance, turbocharged 2.4-liter FA24F engine, and re-tuned transmission gearing with revised front and rear gear ratios.

        "evidence": "Feature elimination strategies are often taken 1) to remove irrelevant or noisy features, 2) to improve classifier performance, and 3) to reduce training and run times. We conducted an experiment to determine whether we could maintain or improve classifier performances by applying the following three-tiered feature elimination approach:\nReduction We reduced the dataset encoded for each class by eliminating features that occur less than twice in the full dataset.\nSelection We iteratively applied Chi-Square feature selection on the reduced dataset, selecting the top percentile of highest ranked features in increments of 5 percent to train and test the support vector model using a linear kernel and 5-fold, stratified cross-validation.\nRank We cumulatively plotted the average F1-score performances of each incrementally added percentile of top ranked features. We report the percentile and count of features resulting in the first occurrence of the highest average F1-score for each class.\nAll experiments were programmed using scikit-learn 0.18.\nThe initial matrices of almost 17,000 features were reduced by eliminating features that only occurred once in the full dataset, resulting in 5,761 features. We applied Chi-Square feature selection and plotted the top-ranked subset of features for each percentile (at 5 percent intervals cumulatively added) and evaluated their predictive contribution using the support vector machine with linear kernel and stratified, 5-fold cross validation.\nIn Figure 2, we observed optimal F1-score performance using the following top feature counts: no evidence of depression: F1: 87 (15th percentile, 864 features), evidence of depression: F1: 59 (30th percentile, 1,728 features), depressive symptoms: F1: 55 (15th percentile, 864 features), depressed mood: F1: 39 (55th percentile, 3,168 features), disturbed sleep: F1: 46 (10th percentile, 576 features), and fatigue or loss of energy: F1: 72 (5th percentile, 288 features) (Figure 1). We note F1-score improvements for depressed mood from F1: 13 at the 1st percentile to F1: 33 at the 20th percentile.\nWe observed peak F1-score performances at low percentiles for fatigue or loss of energy (5th percentile), disturbed sleep (10th percentile) as well as depressive symptoms and no evidence of depression (both 15th percentile) suggesting fewer features are needed to reach optimal performance. In contrast, peak F1-score performances occurred at moderate percentiles for evidence of depression (30th percentile) and depressed mood (55th percentile) suggesting that more features are needed to reach optimal performance. However, one notable difference between these two classes is the dramatic F1-score improvements for depressed mood i.e., 20 point increase from the 1st percentile to the 20th percentile compared to the more gradual F1-score improvements for evidence of depression i.e., 11 point increase from the 1st percentile to the 20th percentile. This finding suggests that for identifying depressed mood a variety of features are needed before incremental gains are observed.\nFeature elimination strategies are often taken 1) to remove irrelevant or noisy features, 2) to improve classifier performance, and 3) to reduce training and run times.",

The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class.",
        "evidence": "Wikipedia is the largest source of open and collaboratively curated knowledge in the world. Introduced in 2001, it has evolved into a reference work with around 5m pages for the English Wikipedia alone. In addition, entities and event pages are updated quickly via collaborative editing and all edits are encouraged to include source citations, creating a knowledge base which aims at being both timely as well as authoritative. As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page. However, not all information sources are equal. The online presence of major news outlets is an authoritative source due to active editorial control and their articles are also a timely container of facts. In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them). However, such an approach lacks in (a) reproducibility since rankings vary with time with obvious bias to recent news (b) maintainability since document acquisition for each entity has to be periodically performed. To this effect, our news suggestion considers a news article as input, and determines if it is valuable for Wikipedia. Specifically, given an input news article INLINEFORM0 and a state of Wikipedia, the news suggestion problem identifies the entities mentioned in INLINEFORM1 whose entity pages can improve upon suggesting INLINEFORM2 . Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower. Third, a good recommendation should be able to identify novel news by minimizing redundancy coming from multiple news articles. Finally, addition of facts is facilitated if the recommendations are fine-grained, i.e., recommendations are made on the section level rather than the page level (placement).\nApproach and Contributions. We propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity's salience in the news article, its relative authority and the novelty of the article to the entity page. The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years. The existing news references in the entity pages along with their reference date act as our ground-truth to evaluate our approach. In summary, we make the following contributions.\nWe propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity’s salience in the news article, its relative authority and the novelty of the article to the entity page.

        "evidence": "The LSTM-Minus method is first proposed in BIBREF6 as a novel way to learn sentence segment embeddings for graph-based dependency parsing, i.e. estimating the most likely dependency tree given an input sentence. For each dependency pair, they divide a sentence into three segments (prefix, infix and suffix), and LSTM-Minus is used to represent each segment. They apply a single LSTM to the whole sentence and use the difference between two hidden states INLINEFORM0 to represent the segment from word INLINEFORM1 to word INLINEFORM2 . This enables their model to learn segment embeddings from information both outside and inside the segments and thus enhancing their model ability to access to sentence-level information. The intuition behind the method is that each hidden vector INLINEFORM3 can capture useful information before and including the word INLINEFORM4 .\nShortly after, lstm-minusconstituency use the same method on the task of constituency parsing, as the representation of a sentence span, extending the original uni-directional LSTM-Minus to the bi-directional case.

        "question": "Does the methodology in this paper perform better than a random classifier?",
        "answer": "Yes, it does.",
        "evidence": "We performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty; this also allows us to compare results with our baseline. We applied a standardization of the features and we used the default configuration for parameters as described in scikit-learn package BIBREF33. We also tested other classifiers (such as K-Nearest Neighbors, Support Vector Machines and Random Forest) but we omit results as they give comparable performances. We remark that our goal is to show that a very simple machine learning framework, with no parameter tuning and optimization, allows for accurate results with our network-based approach.\nWe used the following evaluation metrics to assess the performances of different classifiers (TP=true positives, FP=false positives, FN=false negatives):\nPrecision = $\\frac{TP}{TP+FP}$, the ability of a classifier not to label as positive a negative sample.\nRecall = $\\frac{TP}{TP+FN}$, the ability of a classifier to retrieve all positive samples.\nF1-score = $2 \\frac{\\mbox{Precision} \\cdot \\mbox{Recall}}{\\mbox{Precision} + \\mbox{Recall}}$, the harmonic average of Precision and Recall.\nArea Under the Receiver Operating Characteristic curve (AUROC); the Receiver Operating Characteristic (ROC) curve BIBREF34, which plots the TP rate versus the FP rate, shows the ability of a classifier to discriminate positive samples from negative ones as its threshold is varied; the AUROC value is in the range $[0, 1]$, with the random baseline classifier holding AUROC$=0.5$ and the ideal perfect classifier AUROC$=1$; thus larger AUROC values (and steeper ROCs) correspond to better classifiers.\nIn particular we computed so-called macro average–simple unweighted mean–of these metrics evaluated considering both labels (disinformation and mainstream). We employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.\nFinally, we partitioned networks according to the total number of unique users involved in the sharing, i.e. the number of nodes in the aggregated network represented with a single-layer representation considering together all layers and also pure tweets. A breakdown of both datasets according to size class (and political biases for the US scenario) is provided in Table 1 and Table 2.\nIn Table 3 we first provide classification performances on the US dataset for the LR classifier evaluated on the size class described in Table 1. We can observe that in all instances our methodology performs better than a random classifier (50% AUROC), with AUROC values above 85% in all cases.\nFor what concerns political biases, as the classes of mainstream and disinformation networks are not balanced (e.g., 1,292 mainstream and 4,149 disinformation networks with right bias) we employ a Balanced Random Forest with default parameters (as provided in imblearn Python package BIBREF35). In order to test the robustness of our methodology, we trained only on left-biased networks or right-biased networks and tested on the entire set of sources (relative to the US dataset); we provide a comparison of AUROC values for both biases in Figure 4. We can notice that our multi-layer approach still entails significant results, thus showing that it can accurately distinguish mainstream news from disinformation regardless of the political bias. We further corroborated this result with additional classification experiments, that show similar performances, in which we excluded from the training/test set two specific sources (one at a time and both at the same time) that outweigh the others in terms of data samples–respectively \"breitbart.com\" for right-biased sources and \"politicususa.com\" for left-biased ones.\nWe performed classification experiments on the Italian dataset using the LR classifier and different size classes (we excluded $[1000, +\\infty )$ which is empty); we show results for different evaluation metrics in Table 3. We can see that despite the limited number of samples (one order of magnitude smaller than the US dataset) the performances are overall in accordance with the US scenario. As shown in Table 4, we obtain results which are much better than our baseline in all size classes (see Table 4):\nIn the US dataset our multi-layer methodology performs much better in all size classes except for large networks ($[1000, +\\infty )$ size class), reaching up to 13% improvement on smaller networks ($[0, 100)$ size class);\nIn the IT dataset our multi-layer methodology outperforms the baseline in all size classes, with the maximum performance gain (20%) on medium networks ($[100, 1000)$ size class); the baseline generally reaches bad performances compared to the US scenario.\nOverall, our performances are comparable with those achieved by two state-of-the-art deep learning models for \"fake news\" detection BIBREF9BIBREF36.\nIn order to understand the impact of each layer on the performances of classifiers, we performed additional experiments considering separately each layer (we ignored T and U features relative to pure tweets). In Table 5 we show metrics for each layer and all size classes, computed with a 10-fold stratified shuffle split cross validation, evaluated on the US dataset; in Figure 5 we show AUROC values for each layer compared with the general multi-layer approach. We can notice that both Q and M layers alone capture adequately the discrepancies of the two distinct news domains in the United States as they obtain good results with AUROC values in the range 75%-86%; these are comparable with those of the multi-layer approach which, nevertheless, outperforms them across all size classes.\nWe obtained similar performances for the Italian dataset, as the M layer obtains comparable performances w.r.t multi-layer approach with AUROC values in the range 72%-82%. We do not show these results for sake of conciseness.\nWe further investigated the importance of each feature by performing a $\\chi ^2$ test, with 10-fold stratified shuffle split cross validation, considering the entire range of network sizes $[0, +\\infty )$. We show the Top-5 most discriminative features for each country in Table 6.\nWe can notice the exact same set of features (with different relative orderings in the Top-3) in both countries; these correspond to two global network propertie–LWCC, which indicates the size of the largest cascade in the layer, and SCC, which correlates with the size of the network–associated to the same set of layers (Quotes, Retweets and Mentions).\nWe further performed a $\\chi ^2$ test to highlight the most discriminative features in the M layer of both countries, which performed equally well in the classification task as previously highlighted; also in this case we focused on the entire range of network sizes $[0, +\\infty )$. Interestingly, we discovered exactly the same set of Top-3 features in both countries, namely LWCC, SCC and DWCC (which indicates the depth of the largest cascade in the layer).\nAn inspection of the distributions of all aforementioned features revealed that disinformation news exhibit on average larger values than mainstream news.\nWe can qualitatively sum up these results as follows:\nSharing patterns in the two news domains exhibit discrepancies which might be country-independent and due to the content that is being shared.\nInteractions in disinformation sharing cascades tends to be broader and deeper than in mainstream news, as widely reported in the literature BIBREF8BIBREF2BIBREF7.\nUsers likely make a different usage of mentions when sharing news belonging to the two domains, consequently shaping different sharing patterns.\nSimilar to BIBREF9, we carried out additional experiments to answer the following question: how long do we need to observe a news spreading on Twitter in order to accurately classify it as disinformation or mainstream?\nWith this goal, we built several versions of our original dataset of multi-layer networks by considering in turn the following lifetimes: 1 hour, 6 hours, 12 hours, 1 day, 2 days, 3 days and 7 days; for each case, we computed the global network properties of the corresponding network and evaluated the LR classifier with 10-fold cross validation, separately for each lifetime (and considering always the entire set of networks). We show corresponding AUROC values for both US and IT datasets in Figure 6.\nWe can see that in both countries news diffusion networks can be accurately classified after just a few hours of spreading, with AUROC values which are larger than 80% after only 6 hours of diffusion. These results are very promising and suggest that articles pertaining to the two news domains exhibit discrepancies in their sharing patterns that can be timely exploited in order to rapidly detect misleading items from factual information.\nWe can observe that in all instances our methodology performs better than a random classifier (50% AUROC), with AUROC values above 85% in all cases.",

        "question": "What model do they introduce to solve hierarchically structured prediction problems?",
        "answer": "A novel hierarchical structured neural generation model.",
        "evidence": "Document understanding is one of the critical and challenging tasks in information processing. There have been many related research topics in this direction, such as keyword detection BIBREF0 , BIBREF1 , topic modeling BIBREF2 , BIBREF3 , headline generation BIBREF4 , BIBREF5 and text summarization BIBREF6 , BIBREF7 . Keyword detection and topic modeling aim to describe a document by a few important words or topics (i.e., distributions of words) for concise representation; While headline generation and text summarization attempt to compress the document into one or a few sentences to capture the key information. As we can see, most existing research on document understanding has focused on the coarse-grained understanding of documents by capturing its global semantics. In this paper, we attempt to provide fine-grained understanding of documents by unveiling its inhere content structure BIBREF8 , BIBREF9 , i.e., to understand how the document is organized and what it talks about in each part .\nWe thus introduce the Outline Generation (OG) task in this work. Given a multi-paragraph document, the OG task aims to identify its potential sections and generate the corresponding section headings. Figure FIGREF3 shows some typical outline of articles, where Figure FIGREF3 (a) depicts the outline of a Wikipedia article with a two-level hierarchy, and Figure FIGREF3 (b) depicts a typical outline of a research paper. As we can see, the outline can clearly capture the content structure of a document with concise text descriptions (i.e., section headings), which can not only help navigate the reading but also significantly reduce the cognitive burden over the document. Moreover, outlines can also facilitate a variety of text analysis applications such as text clustering and topic survey.\nIn a conceptual level, the OG task could be viewed as a kind of summarization task. However, from the examples shown in Figure FIGREF3 , we can find clear differences between the OG task and traditional summarization tasks. Firstly, the OG task produces a structured output with short descriptions (i.e., keywords or key phrases), while the output of traditional summarization is usually a set of unstructured sentences. Secondly, the OG task needs to summarize the paragraphs (into sections) in a strict sequential order, while the sentences in traditional summarization usually do not map to the paragraphs linearly. Thirdly, the section headings in one outline usually follow a similar style (e.g., topical headings as in Figure FIGREF3 (a) and functional headings as in Figure FIGREF3 (b)), while there is no such requirements in traditional summarization. Therefore, the OG task is actually a novel structured summarization task with its own special challenges.\nIf we take a further look at the OG task, we can find there are actually two structured prediction problem within it, i.e., to identify a sequence of sections (i.e., paragraphs with coherent information/topics), and to generate a sequence of section headings (i.e., short descriptions that summarize the sections) accordingly. Both problems are non-trivial. For section identification, it is unknown how many sections there are in a document. For section heading generation, headings should be able to reflect the section content in a consistent style. To achieve these two goals, an ideal OG model should be able to capture three levels of coherence, namely the coherence between context paragraphs, that between a section and its heading, and that between context headings. The first one is the foundation for section identification, while the latter two are critical for consistent heading generation.\nIn this work, we formulate the OG task as a hierarchical structured prediction problem and introduce a novel hierarchical structured neural generation model, named HiStGen, to solve it. In this model, we view the section boundary prediction problem as a first-level sequential labeling process, and the section heading generation as a second-level structured prediction which depends on the predicted boundary labels from the lower level. For section identification, we employ a Markov paragraph dependency mechanism to model the coherence in adjacent paragraphs to help decide the section boundaries. For section heading generation, we leverage a section-aware attention mechanism BIBREF10 to allow the decoder to focus on the most informative content within a section for heading generation. Furthermore, we introduce a Markov heading dependency mechanism and a review mechanism BIBREF11 between context headings. The Markov heading dependency mechanism is used for modeling the consistency between adjacent headings, while the review mechanism is employed to avoid the repetition in the generated headings.\nTo facilitate the study and evaluation of the OG task, we build a new benchmark dataset based on Wikipedia articles. As we can see, in most multi-paragraph Wikipedia articles, human editors would segment the article into several sections and provide the outline as an overview of the content structure. Therefore, we can directly leverage these articles to build the benchmark. Specifically, we collect Wikipedia articles with outlines under “celebrity\", “cities” and “music” category, and obtain hundreds of thousands of articles respectively. We remove the outlines from Wikipedia articles to form the raw text input. The task is to recover the sections and section headings simultaneously. We call this benchmark dataset as WIKIOG.\nFor evaluation, we compare with several state-of-the-art methods to verify the effectiveness of our model. Empirical results demonstrate that outline generation for capturing the inherent content structure is feasible and our proposed method can outperform all the baselines significantly. We also provide detailed analysis on the proposed model, and conduct case studies to provide better understanding on the learned content structure.\nThe main contributions of this paper include:\nIn this work, we formulate the OG task as a hierarchical structured prediction problem and introduce a novel hierarchical structured neural generation model, named HiStGen, to solve it.",

        "answer": "All the semantic reasoning tasks that take sentence pair as input.",
        "evidence": "The ability of semantic reasoning is essential for advanced natural language understanding (NLU) systems. Many NLU tasks that take sentence pairs as input, such as natural language inference (NLI) and machine reading comprehension (MRC), heavily rely on the ability of sophisticated semantic reasoning. For instance, the NLI task aims to determine whether the hypothesis sentence (e.g., a woman is sleeping) can be inferred from the premise sentence (e.g., a woman is talking on the phone). This requires the model to read and understand sentence pairs to make the specific semantic inference.\nBidirectional Encoder Representations from Transformer (BERT) BIBREF1 has shown strong ability in semantic reasoning. It was recently proposed and obtained impressive results on many tasks, ranging from text classification, natural language inference, and machine reading comprehension. BERT achieves this by employing two objectives in the pre-training, i.e., the masked language modeling (Masked LM) and the next sentence prediction (NSP). Intuitively, the Masked LM task concerns word-level knowledge, and the NSP task captures the global document-level information. The goal of NSP is to identify whether an input sentence is next to another input sentence. From the ablation study BIBREF1, the NSP task is quite useful for the downstream NLI and MRC tasks (e.g., +3.5% absolute gain on the Question NLI (QNLI) BIBREF2 task).\nDespite its usefulness, we suggest that BERT has not made full use of the document-level knowledge. The sentences in the negative samples used in NSP are randomly drawn from other documents. Therefore, to discriminate against these sentences, BERT is prone to aggregating the shallow semantic, e.g., topic, neglecting context clues useful for detailed reasoning. In other words, the canonical NSP task would encourage the model to recognize the correlation between sentences, rather than obtaining the ability of semantic entailment. This setting weakens the BERT model from learning specific semantic for inference. Another issue that renders NSP less effective is that BERT is order-sensitive. Performance degradation was observed on typical NLI tasks when the order of two input sentences are reversed during the BERT fine-tuning phase. It is reasonable as the NSP task can be roughly analogy to the NLI task when the input comes as (premise, hypothesis), considering the causal order among sentences. However, this identity between NSP and NLI is compromised when the sentences are swapped.\nBased on these considerations, we propose a simple yet effective method, i.e., introducing a IsPrev category to the classification task, which is a symmetric label of IsNext of NSP. The input of samples with IsPrev is the reverse of those with IsNext label. The advantages of using this previous sentence prediction (PSP) are three folds. (1) Learning the contrast between NSP and PSP forces the model to extract more detailed semantic, thereby the model is more capable of discriminating the correlation and entailment. (2) NSP and PSP are symmetric. This symmetric regularization alleviates the influence of the order of the input pair. (3) Empirical results indicate that our method is beneficial for all the semantic reasoning tasks that take sentence pair as input.\nIn addition, to further incorporating the document-level knowledge, NSP and PSP are extended with non-successive sentences, where the label smoothing technique is adopted. The proposed method yields a considerable improvement in our experiments. We evaluate the ability of semantic reasoning on standard NLI and MRC benchmarks, including the challenging HANS dataset BIBREF0. Analytical work on the HANS dataset provides a more comprehensible perspective towards the proposed method. Furthermore, the results on the Chinese benchmarks are provided to demonstrate its generality.\nIn summary, this work makes the following contributions:\nThe supervision signal from the original NSP task is weak for semantic inference. Therefore, a novel method is proposed to remedy the asymmetric issue and enhance the reasoning ability.\nBoth empirical and analytical evaluations are provided on the NLI and MRC datasets, which verifies the effectiveness of using more document-level knowledge.\nEmpirical results indicate that our method is beneficial for all the semantic reasoning tasks that take sentence pair as input.",

        "evidence": "State-of-the-art automatic speech recognition (ASR) systems BIBREF0 have large model capacities and require significant quantities of training data to generalize. Labeling thousands of hours of audio, however, is expensive and time-consuming. A natural question to ask is how to achieve better generalization with fewer training examples. Active learning studies this problem by identifying and labeling only the most informative data, potentially reducing sample complexity. How much active learning can help in large-scale, end-to-end ASR systems, however, is still an open question.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores. In particular, an utterance is considered informative if the most likely prediction has small probability BIBREF1 , or if the predictions are distributed very uniformly over the labels BIBREF2 . Though confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) BIBREF3 , where the informativeness is measured by the norm of the gradient incurred by the instance. EGL has previously been justified as intuitively measuring the expected change in a model's parameters BIBREF3 .We formalize this intuition from the perspective of asymptotic variance reduction, and experimentally, we show EGL to be superior to confidence-based methods on speech recognition tasks. Additionally, we observe that the ranking of samples scored by EGL is not correlated with that of confidence scoring, suggesting EGL identifies aspects of an instance that confidence scores cannot capture.\nIn BIBREF3 , EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular. Gradient-based methods have also found applications outside active learning. For example, BIBREF4 suggests that in stochastic gradient descent, sampling training instances with probabilities proportional to their gradient lengths can speed up convergence. From the perspective of variance reduction, this importance sampling problem shares many similarities to problems found in active learning.\nIn [4], EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular.",

        "answer": "A forecasting model needs to capture the flow of the discussion and real conversations can end or derail at any time.",
        "evidence": "Online discussions often derail into toxic exchanges between participants. Recent efforts mostly focused on detecting antisocial behavior after the fact, by analyzing single comments in isolation. To provide more timely notice to human moderators, a system needs to preemptively detect that a conversation is heading towards derailment before it actually turns toxic. This means modeling derailment as an emerging property of a conversation rather than as an isolated utterance-level event.  ::: Forecasting emerging conversational properties, however, poses several inherent modeling challenges. First, since conversations are dynamic, a forecasting model needs to capture the flow of the discussion, rather than properties of individual comments. Second, real conversations have an unknown horizon: they can end or derail at any time; thus a practical forecasting model needs to assess the risk in an online fashion, as the conversation develops. In this work we introduce a conversational forecasting model that learns an unsupervised representation of conversational dynamics and exploits it to predict future derailment as the conversation develops. By applying this model to two new diverse datasets of online conversations with labels for antisocial events, we show that it outperforms state-of-the-art systems at forecasting derailment.\nForecasting emerging conversational properties, however, poses several inherent modeling challenges.

        "question": "How to always search for the right context?",
        "answer": "The extraction process respects document boundaries, to ensure the authors always search for the right context.",
        "evidence": "We automatically create a test set from the OpenSubtitles corpus BIBREF22 . The goal is to provide a large number of difficult test cases where an English pronoun has to be translated to a German pronoun.\nThe most challenging cases are translating it to either er, sie or es, depending on the grammatical gender of the antecedent. Not only is the translation of it ambiguous, there is also class imbalance in the training data (see Table TABREF18 ). There is roughly a 30% probability that it is aligned to es, which makes it difficult to learn to translate er and sie. We use parsing and automatic co-reference resolution to find translation pairs that satisfy our constraints.\nTo provide a basis for filtering with constraints, we tokenize the whole data set with the Moses tokenizer, generate symmetric word alignments with fast_align BIBREF23 , parse the English text with CoreNLP BIBREF24 , parse the German text with ParZu BIBREF25 and perform coreference resolution on both sides. The coreference chains are obtained with the neural model of CoreNLP for English, and with CorZu for German BIBREF26 , respectively.\nThen we opt for high-precision, aggressive filtering, according to the following protocol: for each pair of sentences INLINEFORM0 in English and German, extract iff\n INLINEFORM0 contains the English pronoun it, and INLINEFORM1 contains a German pronoun that is third person singular (er, sie or es), as indicated by their part-of-speech tags;\nthose pronouns are aligned to each other;\nboth pronouns are in a coreference chain;\ntheir nominal antecedents in the coreference chain are aligned on word level.\nThis removes most candidate pairs, but is necessary to overcome the noise introduced by our preprocessing pipeline, most notably coreference resolution. From the filtered set, we create a balanced test set by randomly sampling 4000 instances of each of the three translations of it under consideration (er, sie, es). We do not balance antecedent distance. See Table TABREF25 for the distribution of pronoun pairs and antecedent distance in the test set.\nFor each sentence pair in the resulting test set, we introduce contrastive translations. A contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one. For an example, see Table TABREF19 , where the pronoun it in the original translation corresponds to sie because the antecedent bat is a feminine noun in German (Fledermaus). We produce wrong translations by replacing sie with one of the other pronouns (er, es).\nNote that, by themselves, these contrastive translations are grammatically correct if the antecedent is outside the current sentence. The test set also contains pronouns with an antecedent in the same sentence (antecedent distance 0). Those examples do not require any additional context for disambiguation and we therefore expect the sentence-level baseline to perform well on them.\nWe take extra care to ensure that the resulting contrastive translations are grammatically correct, because ungrammatical sentences are easily dismissed by an NMT system. For instance, if there are any possessive pronouns (such as seine) in the sentence, we also change their gender to match the personal pronoun replacement.\nThe German coreference resolution system does not resolve es because most instances of es in German are either non-referential forms, or they refer to a clause instead of a nominal antecedent. We limit the test set to nominal antecedents, as these are the only ambiguous cases with respect to translation. For this reason, we have to rely entirely on the English coreference links for the extraction of sentence pairs with it INLINEFORM0 es, as opposed to pairs with it INLINEFORM1 er and it INLINEFORM2 sie where we have coreference chains in both languages.\nOur extraction process respects document boundaries, to ensure we always search for the right context. We extract additional information from the annotated documents, such as the distance (in sentences) between pronouns and their antecedents, the document of origin, lemma, morphology and dependency information if available.\nOur extraction process respects document boundaries, to ensure we always search for the right context.",

        "question": "Whether the authors' proposed approach improves zero-shot translation performance?",
        "answer": "Yes.",
        "evidence": "Although Neural Machine Translation (NMT) has dominated recent research on translation tasks BIBREF0, BIBREF1, BIBREF2, NMT heavily relies on large-scale parallel data, resulting in poor performance on low-resource or zero-resource language pairs BIBREF3. Translation between these low-resource languages (e.g., Arabic$\\rightarrow $Spanish) is usually accomplished with pivoting through a rich-resource language (such as English), i.e., Arabic (source) sentence is translated to English (pivot) first which is later translated to Spanish (target) BIBREF4, BIBREF5. However, the pivot-based method requires doubled decoding time and suffers from the propagation of translation errors.\nOne common alternative to avoid pivoting in NMT is transfer learning BIBREF6, BIBREF7, BIBREF8, BIBREF9 which leverages a high-resource pivot$\\rightarrow $target model (parent) to initialize a low-resource source$\\rightarrow $target model (child) that is further optimized with a small amount of available parallel data. Although this approach has achieved success in some low-resource language pairs, it still performs very poorly in extremely low-resource or zero-resource translation scenario. Specifically, BIBREF8 reports that without any child model training data, the performance of the parent model on the child test set is miserable.\nIn this work, we argue that the language space mismatch problem, also named domain shift problem BIBREF10, brings about the zero-shot translation failure in transfer learning. It is because transfer learning has no explicit training process to guarantee that the source and pivot languages share the same feature distributions, causing that the child model inherited from the parent model fails in such a situation. For instance, as illustrated in the left of Figure FIGREF1, the points of the sentence pair with the same semantics are not overlapping in source space, resulting in that the shared decoder will generate different translations denoted by different points in target space. Actually, transfer learning for NMT can be viewed as a multi-domain problem where each source language forms a new domain. Minimizing the discrepancy between the feature distributions of different source languages, i.e., different domains, will ensure the smooth transition between the parent and child models, as shown in the right of Figure FIGREF1. One way to achieve this goal is the fine-tuning technique, which forces the model to forget the specific knowledge from parent data and learn new features from child data. However, the domain shift problem still exists, and the demand of parallel child data for fine-tuning heavily hinders transfer learning for NMT towards the zero-resource setting.\nIn this paper, we explore the transfer learning in a common zero-shot scenario where there are a lot of source$\\leftrightarrow $pivot and pivot$\\leftrightarrow $target parallel data but no source$\\leftrightarrow $target parallel data. In this scenario, we propose a simple but effective transfer approach, the key idea of which is to relieve the burden of the domain shift problem by means of cross-lingual pre-training. To this end, we firstly investigate the performance of two existing cross-lingual pre-training methods proposed by BIBREF11 in zero-shot translation scenario. Besides, a novel pre-training method called BRidge Language Modeling (BRLM) is designed to make full use of the source$\\leftrightarrow $pivot bilingual data to obtain a universal encoder for different languages. Once the universal encoder is constructed, we only need to train the pivot$\\rightarrow $target model and then test this model in source$\\rightarrow $target direction directly. The main contributions of this paper are as follows:\nWe propose a new transfer learning approach for NMT which uses the cross-lingual language model pre-training to enable a high performance on zero-shot translation.\nWe propose a novel pre-training method called BRLM, which can effectively alleviates the distance between different source language spaces.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches. Meanwhile, the performance on supervised translation direction remains the same level or even better when using our method.\nOur proposed approach significantly improves zero-shot translation performance, consistently surpassing pivoting and multilingual approaches.

Finally, in a collaboration with an HR industry actor, we have obtained a dataset of French video interviews comprising more than 475 positions and 7938 candidates. As they watch candidates' videos, recruiters can like, dislike, shortlist candidates, evaluate them on predefined criteria, or write comments. To simplify the task, we set up a binary classification: candidates who have been liked or shortlisted are considered part of the hirable class and others part of the not hirable class. If multiple annotators have annotated the same candidates, we proceed with a majority vote. In case of a draw, the candidate is considered hirable. It is important to note that the videos are quite different from what could be produced in a laboratory setup.

        "evidence": "Stylometry is defined as, \"the statistical analysis of variations in literary style between one writer or genre and another\". It is a centuries-old practice, dating back the early Renaissance. It is most often used to attribute authorship to disputed or anonymous documents. Stylometry techniques have also successfully been applied to other, non-linguistic fields, such as paintings and music. The main principles of stylometry were compiled and laid out by the philosopher Wincenty Lutosławski in 1890 in his work \"Principes de stylométrie\" BIBREF0 .\nToday, there are millions of users with accounts and profiles on many different social media and networking sites. It is not uncommon for users to have multiple accounts on different social media and networking sites. With so many networking, emailing, and photo sharing sites on the Web, a user often accumulates an abundance of account profiles. There is an increasing focus from the academic and business worlds on aggregating user information across different sites, allowing for the development of more complete user profiles. There currently exist several businesses that focus on this task BIBREF1 , BIBREF2 , BIBREF3 . These businesses use the aggregate profiles for advertising, background checks or customer service related tasks. Moreover, profile matching across social networks, can assist the growing field of social media rumor detection BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , since many malicious rumors are spread on different social media platforms by the same people, using different accounts and usernames.\nMotivated by traditional stylometry and the growing interest in matching user accounts across Internet services, we created models for Digital Stylometry, which fuses traditional stylometry techniques with big-data driven social informatics methods used commonly in analyzing social networks. Our models use linguistic and temporal activity patterns of users on different accounts to match accounts belonging to the same person. We evaluated our models on $11,224$ accounts belonging to $5,612$ distinct users on two of the largest social media networks, Twitter and Facebook. The only information that was used in our models were the time and the linguistic content of posts by the users. We intentionally did not use any other information, especially the potentially personally identifiable information that was explicitly provided by the user, such as the screen name, birthday or location. This is in accordance with traditional stylometry techniques, since people could misstate, omit, or lie about this information. Also, we wanted to show that there are implicit clues about the identities of users in the content (language) and context (time) of the users' interactions with social networks that can be used to link their accounts across different services.\nOther than the obvious technical goal, the purpose of this paper is to shed light on the relative ease with which seemingly innocuous information can be used to track users across social networks, even when signing up on different services using completely different account and profile information (such as name and birthday). This paper is as much of a technical contribution, as it is a warning to users who increasingly share a large part of their private lives on these services.\nThe rest of this paper is structured as follows. In the next sections we will review related work on linking profiles, followed by a description of our data collection and annotation efforts. After that, we discuss the linguistic, temporal and combined temporal-linguistic models developed for linking user profiles. Finally, we discuss and summarize our findings and contributions and discuss possible paths for future work.\nThe only information that was used in our models were the time and the linguistic content of posts by the users.",

It is an example of cannibalization.\nThe term alludes to the Osborne Computer Corporation, whose second product did not become available until more than a year after it was announced. The company's subsequent bankruptcy was widely blamed on reduced sales after the announcement.\nThe Osborne Effect states that prematurely discussing future, unavailable products damages sales of existing products. The name comes from the planned replacement of the Osborne 1, an early personal computer first sold by the Osborne Computer Corporation in 1981. In 1983, founder Adam Osborne pre-announced several next-generation computer models (the Osborne Executive and Osborne Vixen), which were only prototypes, highlighting the fact that they would outperform the existing model as the prototypes dramatically cut down assembly time. A widely held belief was that sales of the Osborne 1 fell sharply as customers anticipated those more advanced systems, leading to a sales decline from which Osborne Computer was unable to recover. This belief appeared in the media almost immediately after the company's September 1983 bankruptcy:\n\nTo give the jazzy $2,495 Osborne Executive a running start, Adam began orchestrating publicity early in 1983. We, along with many other magazines, were shown the machine in locked hotel rooms. We were required not to have anything in print about it until the planned release date in mid-April. As far as we know, nothing did appear in print, but dealers heard about the plans and cancelled orders for the Osborne 1 in droves. In early April, Osborne told dealers he would be showing them the machine on a one-week tour the week of 17 April, and emphasized that the new machine was not a competitor for the Osborne 1. But dealers didn't react the way Osborne expected; said Osborne, \"All of them just cancelled their orders for the Osborne 1.\"\n\nOsborne reacted by drastically cutting prices on the Osborne 1 in an effort to stimulate cash flow. But nothing seemed to work, and for several months sales were practically non-existent.\n\nPre-announcement is done for several reasons: to reassure current customers that there is improvement or lower cost coming, to increase the interest of the media and investors in the company's future prospects, and to intimidate or confuse competitors. When done correctly, the sales or cash flow impact to the company is minimal, with the revenue drop for the current product being offset by orders or completed sales of the new product as it becomes available. However, when the Osborne effect occurs, the quantity of unsold goods increases and the company must react by discounting and/or lowering production of the current product, both of which depress cash flow.",

        "evidence": "On the PDTB corpus, both binary classification and multi-way classification settings are commonly used to evaluate the implicit discourse relation recognition performance. We noticed that all the recent works report class-wise implicit relation prediction performance in the binary classification setting, while none of them report detailed performance in the multi-way classification setting. In the binary classification setting, separate “one-versus-all” binary classifiers were trained, and each classifier is to identify one class of discourse relations. Although separate classifiers are generally more flexible in combating with imbalanced distributions of discourse relation classes and obtain higher class-wise prediction performance, one pair of discourse units may be tagged with all four discourse relations without proper conflict resolution. Therefore, the multi-way classification setting is more appropriate and natural in evaluating a practical end-to-end discourse parser, and we mainly evaluate our proposed models using the four-way multi-class classification setting.\nSince none of the recent previous work reported class-wise implicit relation classification performance in the multi-way classification setting, for better comparisons, we re-implemented the neural tensor network architecture (so-called SWIM in BIBREF18 ) which is essentially a Bi-LSTM model with tensors and report its detailed evaluation result in the multi-way classification setting. As another baseline, we report the performance of a Bi-LSTM model without tensors as well. Both baseline models take two relevant discourse units as the only input.\nFor additional comparisons, We also report the performance of our proposed models in the binary classification setting.\nOn the PDTB corpus, both binary classification and multi-way classification settings are commonly used to evaluate the implicit discourse relation recognition performance.",

In this paper we focus on English as there are several sentiment analysis datasets in English. To make the English sentiment analysis model as generalizable as possible, we first start by training with a large dataset that has product reviews for different categories. Then, using the trained weights from the larger generic dataset, we make the model more specialized for a specific domain. We further train the model with domain-specific English reviews and use this trained model to score reviews that share the same domain from different languages. To be able to employ the trained model, test sets are first translated to English via machine translation and then inference takes place. Figure FIGREF1 shows our multilingual sentiment analysis approach. It is important to note that this approach does not utilize any resource in any of the languages of the test sets (e.g., word embeddings, lexicons, training set).\nDeep learning approaches have been successful in many applications ranging from computer vision to natural language processing BIBREF20 . Recurrent neural network (RNN) including Long Short Term Memory (LSTM) and Gated Recurrent Units (GRU) are subsets of deep learning algorithms where the dependencies between tokens can be used by the model. These models can also be used with variable length input vectors which makes them suitable for text input. LSTM and GRU models allow operations of sequences of vectors over time and have the capability to `remember' previous information BIBREF20 . RNN have been found useful for several natural language processing tasks including language modeling, text classification, machine translation. RNN can also utilize pre-trained word embeddings (numeric vector representations of words trained on unlabeled data) without requiring hand-crafted features. Therefore in this paper, we employ an RNN architecture that takes text and pre-trained word embeddings as inputs and generates a classification result. Word embeddings represent words as numeric vectors and capture semantic information. They are trained in an unsupervised fashion making it useful for our task.\nThe sentiment analysis model that is trained on English reviews has two bidirectional layers, each with 40 neurons and a dropout BIBREF21 of 0.2 is used. The training phase takes pre-trained word embeddings and reviews in textual format, then predicts the polarity of the reviews. For this study, an embedding length of 100 is used (i.e., each word is represented by a vector of length 100). We utilized pre-trained global vectors BIBREF22 .

        "evidence": "Recently, chit-chat dialogue models have achieved improved performance in modelling a variety of conversational domains, including movie subtitles, Twitter chats and help forums BIBREF0, BIBREF1, BIBREF2, BIBREF3. These neural systems were used to model conversational dialogue via training on large chit-chat datasets such as the OpenSubtitles corpus, which contains generic dialogue conversations from movies BIBREF4. The datasets used do not have an explicit dialogue state to be modelled BIBREF5, but rather require the agent to learn the nuances of natural language in the context of casual peer-to-peer interaction.\nMany recent chit-chat systems BIBREF2, BIBREF3 attempt to introduce increased diversity into model responses. However, dialogue systems have also been known to suffer from a lack of coherence BIBREF0. Given an input message history, systems often have difficulty tracking important information such as professions and names BIBREF0. It would be of benefit to create a system which extracts relevant features from the input that indicate which responses would be most appropriate, and conditions on this stored information to select the appropriate response.\nA major problem with existing recurrent neural network (RNN) architectures is that these systems aggregate all input tokens into a state vector, which is passed to a decoder for generation of the final response, or in the case of a neural probabilistic language model BIBREF6, the state at each time step is used to predict the next token in the sequence. Ideally the size of the state should expand with the number of input tokens and should not lose important information about the input. However, RNN states are typically fixed sized, and for any chosen state size, there exists an input sequence length for which the RNN would not be able to store all relevant details for a final response. In addition, the RNN state undergoes constant transformation at each computational step. This makes it difficult to maintain a persistent storage of information that remains constant over many time steps.\nThe introduction of attention mechanisms BIBREF7 has sparked a change in the current design of RNN architectures. Instead of relying fully on a fixed-sized state vector, an attention mechanism allows each decoder word prediction step to extract relevant information from past states through a key-value query mechanism. However, this mechanism connects every input token with all preceeding ones via a computational step, increasing the complexity of the calculation to $O(N^2)$ for an input sequence size N. In the ideal case, the mapping of input conversation history to output response would have a computational complexity of $O(N)$. For this reason, it is desirable to have an information retrieval system that is both scale-able, but not proportional to input length.\nWe study the impact of accessible memory on response coherence by constructing a memory-augmented dialogue system. The motivation is that it would be beneficial to store details of the conversational history in a more permanent memory structure, instead of being captured inside a fixed-sized RNN hidden state. Our proposed system is able to both read and write to a persistent memory module after reading each input utterance. As such, it has access to a stable representation of the input message history when formulating a final response. We explore two distinct memory architectures with different properties, and compare their differences and benefits. We evaluate our proposed memory systems using perplexity evaluation, and compare them to competitive baselines.\nWe study the impact of accessible memory on response coherence by constructing a memory-augmented dialogue system.",

        "question": "Give me a one line summary of the story below: \n\nA long long time ago the Queen of Odisha heard that there was a master stone sculptor who made such stunning statues of the gods that people would weep from happiness at the beauty of the statues if they saw them. One summer day, while resting indolently with the King in the main hall of the royal palace, the Queen suddenly had a thought. \"How nice it would be, King, if we could build some beautiful statutes of Lord Jagannath so that the people can come worship Jagannath, Balabhadra, and Subadhra. What do you think?\" \n\nThe King thought for a few minutes, and then nodded in agreement. \"What do you have in mind, my Queen?\" And so, soon the stone sculptor was summoned to appear before the Court for an appointment to build in his way the statutes of the gods. Soon the monsoon season started and the sculptor appeared in front of the court, awaiting his appointment. He was a humble man from the mountainous regions of Odisha. Even at his best-dressed, one couldn't help but notice his rough hands, and the small sprinkling of dust that seemed ever present in his hair. \n\nThe King and Queen graciously waited as the sculptor bowed and then asked \"Your majesties, what can I do for you?\" The Queen leaned forward in her throne and her voice rang out in the court \"We have heard, o Master Sculptor, of your skills from people far and wide across the Kingdom. We dream of having you put your skills to use to build beautiful statues that will represent Lord Jagannath, Subhadra, and Balabhadra for our people to worship.\"\n\nThe sculptor was silent. As his silence extended, ministers of the court began to feel restless. \"Speak up! How can you be silent when the Queen graces you so!\" But still, the sculptor was silent. \n\nThe King and Queen sat patiently in their thrones as they waited for the sculptor to respond. Perhaps the enormity of the task was too much. Perhaps, the sculptor was thinking of what he should ask for in return. Or even more, perhaps, the sculptor was awed and honored by the request. \n\nAt last, as the shadows from the late afternoon sun began to stretch across the floors of the hall, the sculptor shifted his weight, and opened his mouth to speak. \"Your majesties, you grace me with such a request, I cannot help but oblige. It is an honor.\" At this, the Queen sat as straight as a rod, listening for the words that would come next. \"But, I can do this on one condition only. I will work in a closed hall, where none may enter - regardless of whether they can hear me working or otherwise. None may enter until I open the doors from within and proclaim to all that the statues are completed.\"\n\nThe ministers gasped - what a strange request from this man. Was he a fool? What if he just slept and ate and didn't do any work? How could the King and Queen trust that he would do the work he was promising to do? The Queen looked on thoughtfully. She glanced at the King, and it seemed to her that he agreed on this condition without reservation. She looked at the sculptor and then nodded her assent. \"We decree that you shall build these statues in a hall set aside, into which no one shall enter until your work is complete and you proclaim that to us after opening the doors of the hall from within.\"",

        "question": "What is your motivation of combining Langevin flow and Normalizing flow",
        "answer": "Our major motivation has been discussed in the last paragraph in our original submission. To be specific, our paper is mainly motivated by the current short-run MCMC EBM paper [a], which realizes that the convergent MCMC can not be guaranteed in learning EBM via MLE in practice and the synthesized examples are actually generated by a flow-like generator that is constructed by a short sequence of Langevin steps, i.e., a short-run MCMC. Although the short-run MCMC generator is appealing due to its simplicity of implementation, its training is time-consuming because the short-run MCMC still needs to be built with roughly 100 Langevin steps to ensure a sufficient model capacity. To further reduce the length of the short-run MCMC, we try to use a deterministic transformation, i.e., normalizing flow, to fast initialize the short-run MCMC so that the MCMC can be much shorter.\nThe above main motivation has been also pointed out by Reviewer DUki: \"This paper is strongly motivated by the short-run MCMC energy-based model, and tries to use a normalizing flow model for a nice initialization to shorten MCMC steps even more.\"\nThe motivation of choosing normalizing flow instead of a generic generator, is because the cooperative learning framework needs to incorporate an MLE algorithm of EBM and an MLE of generator. The MLE of a normalizing flow generator will be much more tractable than the MLE of any other generic generator. The latter might resort to either MCMC-based inference to evaluate the posterior distribution or another encoder network for variational inference.\nThe normalizing flow model will also benefit from its cooperation with EBM because its expressivity will be improved by the stochastic sampling process guided by the EBM. [b] has shown that stochasticity overcomes expressivity limitation of normalizing flows resulting from the invertibility constraint. Such a benefit also motivate us to propose the CoopFlow framework. Our experiments have shown that the CoopFlow indeed improves the performance of a single normalizing flow. Here we also want to grant credits to Reviewer 1uN8 who pointed out the related reference [b]. We have added it into our reference. [b] justifies advantage of the combination of stochastic Langevin flow and deterministic normalizing flow.\nWe have revised our paper by explicitly mentioning our motivation we discuss above. Please check the last paragraph in our revised paper. We use red color to highlight our revision. Thank you for your constructive suggestion to improve the presentation of our paper.",
        "evidence": "Normalizing flows are a family of generative models that construct a complex distribution by transforming a simple probability density, such as Gaussian distribution, through a sequence of invertible and differentiable mappings. Due to the tractability of the exact log-likelihood and the efficiency of the inference and synthesis, normalizing flows have gained popularity in density estimation and variational inference. However, for the sake of ensuring the favorable property of closed-form density evaluation, the normalizing flows typically require special designs of the sequence of transformations, which, in general, constrain the expressive power of the models.\nEnergy-based models (EBMs) define an unnormalized probability density function of data, which is the exponential of the negative energy function. The energy function is directly defined on data domain, and assigns each input configuration with a scalar energy value, with lower energy values indicating more likely configurations. Recently, with the energy function parameterized by a modern deep network such as a ConvNet, the ConvNet-EBMs have gained unprecedented success in modeling large-scale data sets and exhibited stunning performance in synthesiz-ing different modalities of data, e.g., videos, volumetric shapes, point clouds and molecules. The parameters of the energy function can be trained by maximum likelihood. However, due to the intractable integral in computing the normalizing constant, the evaluation of the gradient of the log-likelihood typically requires Markov chain Monte Carlo (MCMC) sampling, e.g., Langevin dynamics, to generate samples from the current model. However, the Langevin sampling on a highly multi-modal energy function, due to the use of deep network parameterization, is generally not mixing. When sampling from a density with a multi-modal landscape, the Langevin dynamics, which follows the gradient information, is apt to get trapped by local modes of the density and is unlikely to jump out to explore other isolated modes. Relying on non-mixing MCMC samples, the estimated gradient of the likelihood can be biased, and the resulting learned energy-based model may become an invalid model, which is unable to approximate the data distribution as expected.\nRecently,  propose to train an EBM with a short-run non-convergent Langevin dynamics, and show that even though the energy function is invalid, the short-run MCMC can be treated as a valid flow model that generates realistic examples. This not only provides an explanation of why EBMs with non-convergent MCMC are still capable of synthesizing realistic examples, but also suggests a more practical computationally-affordable way to learn useful generative models under the existing energy-based learning frameworks. Although EBMs have been widely applied to different domains, learning short-run MCMC in the context of EBM is still underexplored.\nIn this paper, we will accept the fact that MCMC sampling is not mixing in practice, and decide to give up the goal of training a valid EBM of data. Instead, we treat the short-run non-convergent Langevin dynamics, which shares parameters with the energy function, as a flow-like transformation that we call the Langevin flow because it can be considered as a noise-injected residual network. Even though implementing a short-run Langevin flow is surprisingly simple, which is nothing but a design of a bottom-up ConvNet for the energy function, it might still require a sufficiently large number of Langevin steps (each Langevin step consists of one step of gradient descent plus a diffusion step) to construct an effective Langevin flow, so that it can be expressive enough to represent and synthesize the data. Motivated by reducing the number of Langevin steps in the Langevin flow for computational efficiency, we propose the CoopFlow model that trains a Langevin flow jointly with a normalizing flow in a cooperative learning scheme, in which the normalizing flow model learns to serve as a rapid sampler to initialize the Langevin flow so that the Langevin flow can be shorter, while the Langevin flow teaches the normalizing flow by short-run MCMC transition toward the EBM so that the normalizing flow can accumulate the temporal difference in the transition to provide better initial samples. Besides, the motivation of using the normalizing flow instead of a generic generator, is because the cooperative learning framework need to incorporate the MLE algorithm of an EBM and the MLE algorithm of a generator. The MLE of a normalizing flow generator will be much more tractable than the MLE of any other generic generator. The latter might resort to either MCMC-based inference to evaluate the posterior distribution or another encoder network for variational inference. In the proposed CoopFlow, the Langevin flow can overcome expressivity limitation of the normalizing flow due to the invertibility constraint. Such a benefit also motivates us to study the CoopFlow framework. To be specific, we understand the dynamics of cooperative learning with short-run non-mixing MCMC by information geometry. We provide justifications that the CoopFlow trained in the context of EBM with non-mixing MCMC is a valid generator, because it converges to a moment matching estimator. Experiments, including image generation, image reconstruction, and latent space interpolation, are conducted to support our justification.\na.

        "evidence": "Disclaimer: Due to the nature of the paper, some examples contain highly offensive language and hate speech. They don't reflect the views of the authors in any way, and the point of the paper is to help fight such speech. Much recent interest has focused on the detection of offensive language and hate speech in online social media. Such language is often associated with undesirable online behaviors such as trolling, cyberbullying, online extremism, political polarization, and propaganda. Thus, offensive language detection is instrumental for a variety of application such as: quantifying polarization BIBREF0, BIBREF1, trolls and propaganda account detection BIBREF2, detecting the likelihood of hate crimes BIBREF3; and predicting conflict BIBREF4. In this paper, we describe our methodology for building a large dataset of Arabic offensive tweets. Given that roughly 1-2% of all Arabic tweets are offensive BIBREF5, targeted annotation is essential for efficiently building a large dataset. Since our methodology does not use a seed list of offensive words, it is not biased by topic, target, or dialect. Using our methodology, we tagged 10,000 Arabic tweet dataset for offensiveness, where offensive tweets account for roughly 19% of the tweets. Further, we labeled tweets as vulgar or hate speech. To date, this is the largest available dataset, which we plan to make publicly available along with annotation guidelines. We use this dataset to characterize Arabic offensive language to ascertain the topics, dialects, and users' gender that are most associated with the use of offensive language. Though we suspect that there are common features that span different languages and cultures, some characteristics of Arabic offensive language is language and culture specific. Thus, we conduct a thorough analysis of how Arabic users use offensive language. Next, we use the dataset to train strong Arabic offensive language classifiers using state-of-the-art representations and classification techniques. Specifically, we experiment with static and contextualized embeddings for representation along with a variety of classifiers such as a deep neural network classifier and Support Vector Machine (SVM).\nThe contributions of this paper are as follows:\nWe built the largest Arabic offensive language dataset to date that includes special tags for vulgar language and hate speech.

        "evidence": "The Kubernetes master node handles the Kubernetes control plane of the cluster, managing its workload and directing communication across the system. The Kubernetes control plane consists of various components, each its own process, that can run both on a single master node or on multiple masters supporting high-availability clusters. The various components of the Kubernetes control plane are as follows:\n\netcd is a persistent, lightweight, distributed, key-value data store that CoreOS has developed. It reliably stores the configuration data of the cluster, representing the overall state of the cluster at any given point of time. etcd favors consistency over availability in the event of a network partition (see CAP theorem). The consistency is crucial for correctly scheduling and operating services.\nThe API server serves the Kubernetes API using JSON over HTTP, which provides both the internal and external interface to Kubernetes. The API server processes and validates REST requests and updates the state of the API objects in etcd, thereby allowing clients to configure workloads and containers across worker nodes. The API server uses etcd's watch API to monitor the cluster, roll out critical configuration changes, or restore any divergences of the state of the cluster back to what the deployer declared. As an example, the deployer may specify that three instances of a particular \"pod\" (see below) need to be running. etcd stores this fact. If the Deployment Controller finds that only two instances are running (conflicting with the etcd declaration), it schedules the creation of an additional instance of that pod.\nThe scheduler is the extensible component that selects on which node an unscheduled pod (the basic entity managed by the scheduler) runs, based on resource availability. The scheduler tracks resource use on each node to ensure that workload is not scheduled in excess of available resources. For this purpose, the scheduler must know the resource requirements, resource availability, and other user-provided constraints or policy directives such as quality-of-service, affinity vs. anti-affinity requirements, and data locality. The scheduler's role is to match resource \"supply\" to workload \"demand\".\nA controller is a reconciliation loop that drives the actual cluster state toward the desired state, communicating with the API server to create, update, and delete the resources it manages (e.g., pods or service endpoints). One kind of controller is a Replication Controller, which handles replication and scaling by running a specified number of copies of a pod across the cluster. It also handles creating replacement pods if the underlying node fails. Other controllers that are part of the core Kubernetes system include a DaemonSet Controller for running exactly one pod on every machine (or some subset of machines), and a Job Controller for running pods that run to completion (e.g., as part of a batch job). Labels selectors that are part of the controller's definition specify the set of pods that a controller manages.\nThe controller manager is a process that manages a set of core Kubernetes controllers.",

First of all, the reason this condition is proposed is that multi-agent reinforcement learning includes exponential growth of the action space in the number of agents. Therefore, we need an assumption to extract the optimal action through only individual utilities rather than the joint action-value estimator.\nThe reason why the state does not exist in Equation (2) is that their paper does not use (global) state information for the agent-wise utility function in the literature. Namely, only partial observation is given for the agent in the execution phase with inaccessibility to the (global) state, especially in SMAC which is a widely-used benchmark in the MARL community. Nevertheless, conceptually, their method can be modified by adding state, but we used the equation written in their original paper as it is.",
        "evidence": "Instead of training a scalar state-action estimator Q π (s, u), distributional RL represents an actionvalue as a random variable, denoted Z π (s, u). The distributional Bellman operator for policy evaluation in single-agent RL can then be expressed as follows:\nwhere S ∼ P (s |s, u), U ∼ π(u|s), and A D = B denotes the two random variables which follow the same probability distribution.\nIQN. Implicit Quantile Networks (IQN) is one of the widely-used single-agent distributional RL methods. IQN approximates the true action-value function using a quantile-based representation of the distributions. To be specific, each trained quantile represent a random variable Z(s, u, ω) which is a reparameterization of risk-level sample ω drawn from a uniform distribution U(0, 1). To train the IQN, one can use the following Huber quantile regression loss:\nwhere Z target is the target network whose parameters are updated periodically from the original action-value estimator Z. (s, u, r, s ) is a tuple of experience transitions from a replay buffer. In distributional RL, weights are used to express level of rewards and next state transitions are generated from the randomness of the environment.\nDistributional MARL. Recently, distributional RL has also been applied to the CTDE regime, but they lack the disentanglement of risk sources. RMIX and DFAC showed promising results by extending the agent-wise utility function from having deterministic variables to random variables. RMIX demonstrates the effectiveness of risk-sensitive MARL via distributional RL, but it is limited since it cannot represent policies which came from different risk sources (i.e., agent-wise risk-seeking yet environmentwise risk-averse policies). DFAC is another distributional MARL framework that uses mean-shape decomposition which separates the mean and variance parts of the utility functions to handle value function factorization. They propose DDN and DMIX as the DFAC variants of VDN and QMIX, respectively. DFAC extends IQN, a single-agent distributional RL algorithm, to learn the randomness of the environment. However, they do not consider the agent-wise risk that arises when learning networks with limited expressive power such as QMIX. Also, they only demonstrate risk-neutral policies, so it is questionable whether DFAC could handle risk-sensitive policies.\nDistributional MARL.

However, they do not consider the agent-wise risk that arises when learning networks with limited expressive power such as QMIX. Also, they only demonstrate risk-neutral policies, so it is questionable whether DFAC could handle risk-sensitive policies.",

        "question": "How was Napoleon defeated?",
        "evidence": "Napoleon Bonaparte (born Napoleone Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a Corsica-born French military commander and political leader who rose to prominence during the French Revolution and led successful campaigns during the Revolutionary Wars. He was the de facto leader of the French Republic as First Consul from 1799 to 1804, then Emperor of the French from 1804 until 1814 and again in 1815. Napoleon's political and cultural legacy endures to this day, as a highly celebrated and controversial leader. He initiated many liberal reforms that have persisted in society, and is considered one of the greatest military commanders in history. His campaigns are still studied at military academies worldwide. Between three and six million civilians and soldiers died in what became known as the Napoleonic Wars.\n\nNapoleon was born on the island of Corsica, not long after its annexation by France, to a native family descending from minor Italian nobility. He supported the French Revolution in 1789 while serving in the French army, and tried to spread its ideals to his native Corsica. He rose rapidly in the Army after he saved the governing French Directory by firing on royalist insurgents. In 1796, he began a military campaign against the Austrians and their Italian allies, scoring decisive victories and becoming a national hero. Two years later, he led a military expedition to Egypt that served as a springboard to political power. He engineered a coup in November 1799 and became First Consul of the Republic.\n\nDifferences with the United Kingdom meant France faced the War of the Third Coalition by 1805. Napoleon shattered this coalition with victories in the Ulm campaign, and at the Battle of Austerlitz, which led to the dissolution of the Holy Roman Empire. In 1806, the Fourth Coalition took up arms against him. Napoleon defeated Prussia at the battles of Jena and Auerstedt, marched the Grande Armée into Eastern Europe, and defeated the Russians in June 1807 at Friedland, forcing the defeated nations of the Fourth Coalition to accept the Treaties of Tilsit. Two years later, the Austrians challenged the French again during the War of the Fifth Coalition, but Napoleon solidified his grip over Europe after triumphing at the Battle of Wagram.\n\nHoping to extend the Continental System, his embargo against Britain, Napoleon invaded the Iberian Peninsula and declared his brother Joseph the King of Spain in 1808. The Spanish and the Portuguese revolted in the Peninsular War aided by a British army, culminating in defeat for Napoleon's marshals. Napoleon launched an invasion of Russia in the summer of 1812. The resulting campaign witnessed the catastrophic retreat of Napoleon's Grande Armée. In 1813, Prussia and Austria joined Russian forces in a Sixth Coalition against France, resulting in a large coalition army defeating Napoleon at the Battle of Leipzig. The coalition invaded France and captured Paris, forcing Napoleon to abdicate in April 1814. He was exiled to the island of Elba, between Corsica and Italy. In France, the Bourbons were restored to power.\n\nNapoleon escaped in February 1815 and took control of France. The Allies responded by forming a Seventh Coalition, which defeated Napoleon at the Battle of Waterloo in June 1815. The British exiled him to the remote island of Saint Helena in the Atlantic, where he died in 1821 at the age of 51.\n\nNapoleon had an extensive impact on the modern world, bringing liberal reforms to the lands he conquered, especially the regions of the Low Countries, Switzerland and parts of modern Italy and Germany. He implemented many liberal policies in France and Western Europe.",

        "evidence": "The NLP community is revisiting the role of linguistic structure in applications with the advent of contextual word representations (cwrs) derived from pretraining language models on large corpora BIBREF2, BIBREF3, BIBREF4, BIBREF5. Recent work has shown that downstream task performance may benefit from explicitly injecting a syntactic inductive bias into model architectures BIBREF6, even when cwrs are also used BIBREF7. However, high quality linguistic structure annotation at a large scale remains expensive—a trade-off needs to be made between the quality of the annotations and the computational expense of obtaining them. Shallow syntactic structures (BIBREF8; also called chunk sequences) offer a viable middle ground, by providing a flat, non-hierarchical approximation to phrase-syntactic trees (see Fig. FIGREF1 for an example). These structures can be obtained efficiently, and with high accuracy, using sequence labelers. In this paper we consider shallow syntax to be a proxy for linguistic structure.\nWhile shallow syntactic chunks are almost as ubiquitous as part-of-speech tags in standard NLP pipelines BIBREF9, their relative merits in the presence of cwrs remain unclear. We investigate the role of these structures using two methods. First, we enhance the ELMo architecture BIBREF0 to allow pretraining on predicted shallow syntactic parses, instead of just raw text, so that contextual embeddings make use of shallow syntactic context (§SECREF2). Our second method involves classical addition of chunk features to cwr-infused architectures for four different downstream tasks (§SECREF3). Shallow syntactic information is obtained automatically using a highly accurate model (97% $F_1$ on standard benchmarks). In both settings, we observe only modest gains on three of the four downstream tasks relative to ELMo-only baselines (§SECREF4).\nRecent work has probed the knowledge encoded in cwrs and found they capture a surprisingly large amount of syntax BIBREF10, BIBREF1, BIBREF11. We further examine the contextual embeddings obtained from the enhanced architecture and a shallow syntactic context, using black-box probes from BIBREF1. Our analysis indicates that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo embeddings (§SECREF18).\nOverall, our findings show that while shallow syntax can be somewhat useful, ELMo-style pretraining discovers representations which make additional awareness of shallow syntax largely redundant.\nOur analysis indicates that our shallowsyntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo embeddings.",

        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nMoreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set.

        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nWe extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese.",

We observe that recently proposed QA datasets usually focus on formal domains, e.g. CNN/DailyMail BIBREF4 and NewsQA BIBREF5 on news articles; SQuAD BIBREF6 and WikiMovies BIBREF7 that use Wikipedia.\nIn this paper, we propose the first large-scale dataset for QA over social media data. Rather than naively obtaining tweets from Twitter using the Twitter API which can yield irrelevant tweets with no valuable information, we restrict ourselves only to tweets which have been used by journalists in news articles thus implicitly implying that such tweets contain useful and relevant information. To obtain such relevant tweets, we crawled thousands of news articles that include tweet quotations and then employed crowd-sourcing to elicit questions and answers based on these event-aligned tweets. Table TABREF3 gives an example from our TweetQA dataset. It shows that QA over tweets raises challenges not only because of the informal nature of oral-style texts (e.g. inferring the answer from multiple short sentences, like the phrase “so young” that forms an independent sentence in the example), but also from tweet-specific expressions (such as inferring that it is “Jay Sean” feeling sad about Paul's death because he posted the tweet).\nFurthermore, we show the distinctive nature of TweetQA by comparing the collected data with traditional QA datasets collected primarily from formal domains. In particular, we demonstrate empirically that three strong neural models which achieve good performance on formal data do not generalize well to social media data, bringing out challenges to developing QA systems that work well on social media domains.\nIn summary, our contributions are:\nTo obtain such relevant tweets, we crawled thousands of news articles that include tweet quotations and then employed crowd-sourcing to elicit questions and answers based on these event-aligned tweets.",

It was named in 1867 by the French naturalist Alfred Grandidier in honor of the French navy surgeon and naturalist Charles Coquerel. Coquerel's coua is approximately 40 cm (16 in) in length and has a large blue patch of bare skin around the eye, a characteristic of the Coua genus that is similar to African turacos. The plumage is silky, the crown is black, the upper parts and tail are light brown or greyish-brown, and the lower breast and belly is suffused with red. The iris is red and the beak and legs are slaty grey. As a member of the cuckoo family, it has a reversible third toe and resembles the coucal in its method of scrambling through tangled bushes and lianas while searching for food.

        "evidence": "Over the few past years, the emergence of deep neural networks has fundamentally changed the design of entity detection systems. Consequently, recurrent neural networks (RNN) have found popularity in the field since they are able to learn long term dependencies of sequential data. The recent success of neural network based architectures principally comes from its deep structure. Training a deep neural network, however, is a difficult problem due to vanishing or exploding gradients. In order to solve this, LSTMs were proposed. An LSTM is an internal memory cell controlled by forget gate and input gate networks. A forget gate in an LSTM layer which determines how much prior memory should be passed into the next time increment. Similarly, an input gate scales new input to memory cells. Depending on the states of both gates, LSTM is able to capture long-term or short-term dependencies for sequential data. This is an ideal property for many NLP tasks.\nThe architecture of our proposed model is shown in Figure 2. The input is a list of tokens and the output are the predicted entity types. The ELMo embeddings are then used with a residual LSTM to learn informative morphological representations from the character sequence of each token.

        "evidence": "Learning semantic representations (embeddings) of different entities, such as textual, commercial, and physical, has been a recent and active area of research. Such representations can facilitate applications that rely on a notion of similarity, for example recommendation systems and ranking algorithms in e-commerce.\nIn natural language processing, word2vec BIBREF0 learns vector representations of words from large quantities of text, where each word is mapped to a $d$-dimensional vector such that semantically similar words have geometrically closer vectors. This is achieved by predicting either the context words appearing in a window around a given target word (skip-gram model), or the target word given the context (CBOW model). The main assumption is that words appearing frequently in similar contexts share statistical properties (the distributional hypothesis). Crucially, word2vec models, like many other word embedding models, preserve sequential information encoded in text so as to leverage word co-occurrence statistics. The skip-gram model has been adapted to other domains in order to learn dense representations of items other than words. For example, product embeddings in e-commerce BIBREF1 or vacation rental embeddings in the hospitality domain BIBREF2 can be learned by treating purchase histories or user click sequences as sentences and applying a word2vec approach.\nMost of the prior work on item embedding exploit the co-occurrence of items in a sequence as the main signal for learning the representation. One disadvantage of this approach is that it fails to incorporate rich structured information associated with the embedded items. For example, in the travel domain, where we seek to embed hotels and other travel-related entities, it could be helpful to encode explicit information such as user ratings, star ratings, hotel amenities, and location in addition to implicit information encoded in the click-stream.\nIn this work, we propose an algorithm for learning hotel embeddings that combines sequential user click information in a word2vec approach with additional structured information about hotels. We propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes. In experimental results, we show that enhancing the neural network to jointly encode click and supplemental structured information outperforms a skip-gram model that encodes the click information alone. The proposed architecture also naturally handles the cold-start problem for hotels with little or no historical clicks. Specifically, we can infer an embedding for these properties by leveraging their supplemental structured metadata.\nCompared to previous work on item embeddings, the novel contributions of this paper are as follows:\nWe propose a novel framework for fusing multiple sources of information about an item (such as user click sequences and item-specific information) to learn item embeddings via self-supervised learning.\nWe generate an interpretable embedding which can be decomposed into sub-embeddings for clicks, location, ratings, and attributes, and employed either as separate component embeddings or a single, unified embedding.\nIt is also dynamic, meaning it is easy to reflect future changes in attributes such as star-rating or addition of amenities in the embedding vectors without retraining.\nWe address the cold-start problem by including hotel metadata which are independent of user click-stream interactions and available for all hotels. This helps us to better impute embeddings for sparse items/hotels.\nWe show significant gains over previous work based on click-embedding in several experimental studies.\nThe structure of the remainder of this paper is as follows. Section 2 gives an overview of some of the recent works on neural embedding. Section 3 provides details of the proposed framework, including the neural network architecture, training methodology, and how the cold-start problem is addressed. In Section 4, we present experimental results on several different tasks and a comparison with previous state-of-the-art work. Section 5 concludes the paper.\nIt is also dynamic, meaning it is easy to reflect future changes in attributes such as star-rating or addition of amenities in the embedding vectors without retraining.",

Switzerland has maintained a policy of armed neutrality since the 16th century and has not fought an international war since 1815. It joined the United Nations only in 2002, but pursues an active foreign policy that include frequent involvement in peace-building processes worldwide.\n\nSwitzerland is the birthplace of the Red Cross, one of the world's oldest and best-known humanitarian organisations, and hosts the headquarters or offices of most major international institutions, including the WTO, the WHO, the ILO, FIFA, and the United Nations. It is a founding member of the European Free Trade Association (EFTA), but not part of the European Union (EU), the European Economic Area, or the Eurozone; however, it participates in the European single market and the Schengen Area through bilateral treaties. Switzerland is a federal republic composed of 26 cantons, with federal authorities based in Bern.\n\nIt has four main linguistic and cultural regions: German, French, Italian and Romansh. Although most Swiss are German-speaking, national identity is fairly cohesive, being rooted in a common historical background, shared values such as federalism and direct democracy, and Alpine symbolism. Swiss identity transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation (\"nation of volition\") rather than a nation state.",

We choose several target domains from educational controversies, such as homeschooling, single-sex education, or mainstreaming. A novel aspect of the corpus is its coverage of different registers of user-generated Web content, such as comments to articles, discussion forum posts, blog posts, as well as professional newswire articles.\nSince the data come from a variety of sources and no assumptions about its actual content with respect to argumentation can be drawn, we conduct two extensive annotation studies. In the first study, we tackle the problem of relatively high “noise” in the retrieved data. In particular, not all of the documents are related to the given topics in a way that makes them candidates for further deep analysis of argumentation (this study results into 990 annotated documents). In the second study, we discuss the selection of an appropriate argumentation model based on evidence in argumentation research and propose a model that is suitable for analyzing micro-level argumention in user-generated Web content. Using this model, we annotate 340 documents (approx. 90,000 tokens), reaching a substantial inter-annotator agreement. We provide a hand-analysis of all the phenomena typical to argumentation that are prevalent in our data. These findings may also serve as empirical evidence to issues that are on the spot of current argumentation research.\nFrom the computational perspective, we experiment on the annotated data using various machine learning methods in order to extract argument structure from documents. We propose several novel feature sets and identify configurations that run best in in-domain and cross-domain scenarios. To foster research in the community, we provide the annotated data as well as all the experimental software under free license.\nThe rest of the article is structured as follows. First, we provide an essential background in argumentation theory in section SECREF2 . Section SECREF3 surveys related work in several areas.

BERT is a multi-layer bidirectional transformer encoder trained on the English Wikipedia and the Book Corpus containing 2,500M and 800M tokens, respectively, and has two models named BERTbase and BERTlarge. BERTbase contains an encoder with 12 layers (transformer blocks), 12 self-attention heads, and 110 million parameters whereas BERTlarge has 24 layers, 16 attention heads, and 340 million parameters. Extracted embeddings from BERTbase have 768 hidden dimensions BIBREF11. As the BERT model is pre-trained on general corpora, and for our hate speech detection task we are dealing with social media content, therefore as a crucial step, we have to analyze the contextual information extracted from BERT' s pre-trained layers and then fine-tune it using annotated datasets. By fine-tuning we update weights using a labelled dataset that is new to an already trained model. As an input and output, BERT takes a sequence of tokens in maximum length 512 and produces a representation of the sequence in a 768-dimensional vector. BERT inserts at most two segments to each input sequence, [CLS] and [SEP]. [CLS] embedding is the first token of the input sequence and contains the special classification embedding which we take the first token [CLS] in the final hidden layer as the representation of the whole sequence in hate speech classification task. The [SEP] separates segments and we will not use it in our classification task. To perform the hate speech detection task, we use BERTbase model to classify each tweet as Racism, Sexism, Neither or Hate, Offensive, Neither in our datasets. In order to do that, we focus on fine-tuning the pre-trained BERTbase parameters.

        "question": "Does modeling the dependency structure directly via tree encoders outperform a sequential BiLSTM architecture?",
        "answer": "No, it doesn't.",
        "evidence": "Semantic parsing is a task of transducing natural language to meaning representations, which in turn can be expressed through many different semantic formalisms including lambda calculus BIBREF1, DCS BIBREF2, Discourse Representation Theory (DRT) BIBREF3, AMR BIBREF4 and so on. This availability of annotated data in English has translated into the development of a plethora of models, including encoder-decoders BIBREF5, BIBREF6 as well as tree or graph-structured decoders BIBREF5, BIBREF7, BIBREF0, BIBREF8.\nWhereas the majority of semantic banks focus on English, recent effort has focussed on building multilingual representations, e.g. PMB BIBREF9, MRS BIBREF10 and FrameNetBIBREF11. However, manually annotating meaning representations in a new language is a painstaking process which explains why there are only a few datasets available for different formalisms in languages other than English. As a consequence, whereas the field has made great advances for English, little work has been done in other languages.\nWe ask: can we learn a semantic parser for English and test it where in another where annotations are not available? What would that require?\nTo answer this question, previous work have leveraged machine translation techniques to map the semantics from a language to another BIBREF12. However, these methods require parallel corpora to extract automatic alignments which are often noisy or not available at all.\nIn this paper we explore parameter-shared models instead, where a model is trained on English using language independent features and tested in a target language.\nTo show how this approach performs, we focus on the Parallel Meaning Bank BIBREF13 – a multilingual semantic bank, where sentences in English, German, Italian and Dutch have been annotated with their meaning representations. The annotations in the PMB are based on Discourse Representation Theory BIBREF3, a popular theory of meaning representation designed to account for intra and inter-sentential phenomena, like temporal expressions and anaphora. Figure 1 shows an example DRT for the sentence `I sat down and opened my laptop' in its canonical `box' representation. A DRS is a nested structure with the top part containing the discourse references and the bottom with unary and binary predicates, as well as semantic constants (e.g. `speaker'). DRS can be linked to each other via logic operator (e.g. $\\lnot $, $\\rightarrow $, $\\diamond $) or, as in this case, discourse relations (e.g. CONTINUATION, RESULT, ELABORATION, etc.).\nTo test our approach we leverage the DRT parser of liu2018discourse, an encoder-decoder architecture where the meaning representation is reconstructed in three stages, coarse-to-fine, by first building the DRS skeleton (i.e. the `box' structures) and then fill each DRS with predicates and variables. Whereas the original parser utilizes a sequential Bi-LSTM encoder with monolingual lexical features, we experiment with language-independent features in the form of cross-lingual word-embeddings, universal PoS tags and universal dependencies. In particular, we also make use of tree encoders to assess whether modelling syntax can be beneficial in cross-lingual settings, as shown for other semantic tasks (e.g. negation scope detection BIBREF14).\nResults show that language-independent features are a valid alternative to projection methods for cross-lingual semantic parsing. We show that adding dependency relation as features is beneficial, even when they are the only feature used during encoding. However, we also show that modeling the dependency structure directly via tree encoders does not outperform a sequential BiLSTM architecture for the three languages we have experimented with.\nHowever, we also show that modeling the dependency structure directly via tree encoders does not outperform a sequential BiLSTM architecture for the three languages we have experimented with.",

        "evidence": "Automated coding of political event data, or the record of who-did-what-to-whom within the context of political actions, has existed for roughly two decades. The approach has remained largely the same during this time, with the underlying coding procedures not updating to reflect changes in natural language processing (NLP) technology. These NLP technologies have now advanced to such a level, and with accompanying open-source software implementations, that their inclusion in the event-data coding process comes as an obvious advancement. When combined with changes in how news content is obtained, the ability to store and process large amounts of text, and enhancements based on two decades worth of event-data experience, it becomes clear that political event data is ready for a next generation dataset.\nIn this chapter, I provide the technical details for creating such a next-generation dataset. The technical details lead to a pipeline for the production of the Phoenix event dataset. The Phoenix dataset is a daily updated, near-real-time political event dataset. The coding process makes use of open-source NLP software, an abundance of online news content, and other technical advances made possible by open-source software. This enables a dataset that is transparent and replicable, while providing a more accurate coding process than previously possible. Additionally, the dataset's near-real-time nature also enables many applications that were previously impossible with batch-updated datasets, such as monitoring of ongoing events. Thus, this dataset provides a significant improvement over previous event data generation efforts.\nIn the following sections I briefly outline the history of computer-generated political event data to this point in history. I then outline what the “next generation” of event data should look like. Following this, I discuss the many facets of creating a real-time political event dataset, mainly from a technological and infrastructure standpoint.

        "evidence": "Short Circuit is a 1986 American science fiction comedy film directed by John Badham and written by S. S. Wilson and Brent Maddock. The film's plot centers on an experimental military robot that is struck by lightning and gains a human-like intelligence, prompting it to escape its facility to learn more about the world. The film stars Ally Sheedy, Steve Guttenberg, Fisher Stevens, Austin Pendleton and G. W. Bailey, with Tim Blaney as the voice of the robot named \"Number 5\". A sequel, Short Circuit 2, was released in 1988, directed by Kenneth Johnson.\n\nNOVA Laboratory robotics experts Newton Crosby and Ben Jabituya have developed several prototype robots called S.A.I.N.T. (Strategic Artificially Intelligent Nuclear Transport) for the U.S. military to use in Cold War operations, though they would rather seek peaceful applications of the robots. After a live demonstration for the military, one of the units, S.A.I.N.T. Number 5, is struck by lightning arcing through the lab's power grid. This scrambles its programming and makes it sentient, resulting in its escape from the NOVA facility.\n\nThe robot finds itself in Astoria, Oregon, and is found by Stephanie Speck, an animal caregiver, who mistakes him for an alien. She takes the robot into her home, where she provides him with \"input\" in the form of visual and verbal stimuli, allowing the robot to improve its language skills. Stephanie continues to help the curious Number 5 robot learn about the world. She eventually discovers that Number 5 was built by NOVA, and contacts them about the lost robot. Nova's CEO, Dr. Howard Marner, orders Crosby and Ben to recover him, so they can disassemble and rebuild him. While waiting for NOVA to arrive, Number 5 learns about death when he accidentally crushes a grasshopper and concludes that if NOVA disassembles him, he will die, and escapes in Stephanie's food truck. However, NOVA uses a tracking device on Number 5 to corner him and deactivate the robot for return to the facility. During transport, Number 5 reactivates himself and removes the tracking device, and flees back to Stephanie.\n\nBecause of these unusual actions, Crosby tries to convince Howard that something has changed with Number 5's programming and that they should take care not to damage it in their recovery efforts so that he can examine them later. Howard instead sends their security chief Captain Skroeder and three other S.A.I.N.T. prototypes to capture Number 5 by force, ignoring Crosby's concerns. Number 5 outwits the other robots and reprograms their personalities to act like The Three Stooges, allowing him to escape. Number 5 “kidnaps” Crosby, takes him to Stephanie, and convinces Crosby of his sentience. They find that Skroeder has called in the United States Army to capture Number 5, and on his orders, restrain Crosby and Stephanie so he can open fire. To protect his friends, Number 5 leads the Army away and appears to be destroyed by a helicopter missile. Stephanie is devastated as Skroeder's men scrounge the remains of Number 5 as trophies, prompting Crosby to resign from NOVA and drive away with Stephanie in the NOVA van. Howard is dismayed over the loss of his research and dismisses Skroeder for insubordination.\n\nCrosby and Stephanie are surprised to discover that Number 5 had hidden under the van, having assembled a decoy of himself from spare parts to mislead the military. Crosby suggests taking Number 5 to a secluded ranch in Montana, where there will be much \"input\" for the robot, and Stephanie agrees to come with them. As they drive off, Number 5 asserts that his name should now be \"Johnny 5\" based on the El DeBarge song \"Who's Johnny\" which had been playing on the van's radio.",

First and foremost, the technology of the time period did not have any of the capabilities of Artificial General Intelligence, which is confirmed by the programmers confusion by number 5 not abiding its programming.  Given the amount of input that number 5 must have extracted, processed, stored, and analyzed, there were insufficient compute resources of the time period to support this type of live streaming, instantaneous processing and analysis.  \nJohnny 5 was alive because it was able to learn what death was, become afraid of it, and fight for his ability to survive.  Johnny 5 also learned how to outwit his opponents without the use of excessive force, while also using comedy to disarm his foes.  In the end, it was able to trick his would be destroyers into believing it was dead, allowing him to escape into a life with his friends doing what he loves, reading input.  \nWhat better proof than this, of the miracle of life, is for someone to fight for it, and live.",

        "question": "What are the two variants of Binary PV-DBOW evaluated by the authors?",
        "answer": "one predicting words in documents and one predicting words and bigrams.",
        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nWe therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams.",

        "evidence": "Suppose a user wants to write a sentence “I will be 10 minutes late.” Ideally, she would type just a few keywords such as “10 minutes late” and an autocomplete system would be able to infer the intended sentence (Figure FIGREF1). Existing left-to-right autocomplete systems BIBREF0, BIBREF1 can often be inefficient, as the prefix of a sentence (e.g. “I will be”) fails to capture the core meaning of the sentence. Besides the practical goal of building a better autocomplete system, we are interested in exploring the tradeoffs inherent to such communication schemes between the efficiency of typing keywords, accuracy of reconstruction, and interpretability of keywords.\nOne approach to learn such schemes is to collect a supervised dataset of keywords-sentence pairs as a training set, but (i) it would be expensive to collect such data from users, and (ii) a static dataset would not capture a real user's natural predilection to adapt to the system BIBREF2. Another approach is to avoid supervision and jointly learn a user-system communication scheme to directly optimize the combination of efficiency and accuracy. However, learning in this way can lead to communication schemes that are uninterpretable to humans BIBREF3, BIBREF4 (see Appendix for additional related work).\nIn this work, we propose a simple, unsupervised approach to an autocomplete system that is efficient, accurate, and interpretable. For interpretability, we restrict keywords to be subsequences of their source sentences based on the intuition that humans can infer most of the original meaning from a few keywords. We then apply multi-objective optimization approaches to directly control and achieve desirable tradeoffs between efficiency and accuracy.\nWe observe that naively optimizing a linear combination of efficiency and accuracy terms is unstable and leads to suboptimal schemes. Thus, we propose a new objective which optimizes for communication efficiency under an accuracy constraint. We show this new objective is more stable and efficient than the linear objective at all accuracy levels.\nAs a proof-of-concept, we build an autocomplete system within this framework which allows a user to write sentences by specifying keywords. We empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences. Finally, we demonstrate that humans can easily adapt to the keyword-based autocomplete system and save nearly 50% of time compared to typing a full sentence in our user study.\nAnother approach is to avoid supervision andjointly learn a user-system communication scheme to directly optimize the combination of efficiency and accuracy. However, learning in this way can lead to communication schemes that are uninterpretable to humans [21, 27] (see Appendix A for additional related work).",

As illustrated in Figure FIGREF1, our key idea is that we can exploit discourse relations BIBREF4 to efficiently propagate polarity from seed predicates that directly report one's emotions (e.g., “to be glad” is positive). Suppose that events $x_1$ are $x_2$ are in the discourse relation of Cause (i.e., $x_1$ causes $x_2$). If the seed lexicon suggests $x_2$ is positive, $x_1$ is also likely to be positive because it triggers the positive emotion. The fact that $x_2$ is known to be negative indicates the negative polarity of $x_1$. Similarly, if $x_1$ and $x_2$ are in the discourse relation of Concession (i.e., $x_2$ in spite of $x_1$), the reverse of $x_2$'s polarity can be propagated to $x_1$. Even if $x_2$'s polarity is not known in advance, we can exploit the tendency of $x_1$ and $x_2$ to be of the same polarity (for Cause) or of the reverse polarity (for Concession) although the heuristic is not exempt from counterexamples. We transform this idea into objective functions and train neural network models that predict the polarity of a given event.\nIn this paper, we propose a simple and effective method for learning affective events that only requires a very small seed lexicon and a large raw corpus.

The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called \"runs\". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter).\n\nThe principal objective of the batting team is to have a player reach first base safely; this generally occurs either when the batter hits the ball and reaches first base before an opponent retrieves the ball and touches the base, or when the pitcher persists in throwing the ball out of the batter's reach. Players on the batting team who reach first base without being called \"out\" can attempt to advance to subsequent bases as a runner, either immediately or during teammates' turns batting. The fielding team tries to prevent runs by getting batters or runners \"out\", which forces them out of the field of play. The pitcher can get the batter out by throwing three pitches which result in strikes, while fielders can get the batter out by catching a batted ball before it touches the ground, and can get a runner out by tagging them with the ball while the runner is not touching a base.\n\nThe opposing teams switch back and forth between batting and fielding; the batting team's turn to bat is over once the fielding team records three outs. One turn batting for each team constitutes an inning. A game is usually composed of nine innings, and the team with the greater number of runs at the end of the game wins.

In detail, the left part of the chart shows that the leaf-LSTM is the most effective option compared to its competitors. Note that the sequential leaf-LSTM is somewhat superior or competitive than the bidirectional leaf-LSTM when both have a comparable number of parameters. We conjecture this may because a backward LSTM does not add additional useful knowledge when the structure of a sentence is already known.

Rather than requiring one best answer, this task emphasizes more on ranking a set of candidate entities from the knowledge graph.\nSimilar to BIBREF2 , we use two measures as our evaluation metrics. (1) Mean Rank: the averaged rank of correct entities or relations; (2) Hits@p: the proportion of valid entities or relations ranked in top $p$ predictions. Here, we set $p=10$ for entities and $p=1$ for relations. A lower Mean Rank and a higher Hits@p should be achieved by a good embedding model. We call this evaluation setting “Raw”. Since a false predicted triplet may also exist in knowledge graphs, it should be regard as a valid triplet. Hence, we should remove the false predicted triplets included in training, validation and test sets before ranking (except the test triplet of interest). We call this evaluation setting “Filter”. The evaluation results are reported under these two settings.\nWe select the margin $\\gamma $ among $\\lbrace 1, 2\\rbrace $ , the embedding dimension $d$ among $\\lbrace 20, 50, 100\\rbrace $ , the regularization $\\eta $ among $\\lbrace 0, 1E{-5}, 1E{-6}\\rbrace $ , two learning rates $\\lambda _s$ and $\\lambda _t$ among $\\lbrace 0.001, 0.01, 0.05\\rbrace $ to learn the parameters of structure and text encoding. The dissimilarity measure is set to either $L_1$ or $\\lbrace 1, 2\\rbrace $0 distance.\nIn order to speed up the convergence and avoid overfitting, we initiate the structure embeddings of entity and relation with the results of TransE. The embedding of a word is initialized by averaging the linked entity embeddings whose description include this word. The rest parameters are initialized by randomly sampling from uniform distribution in $[-0.1, 0.1]$ .\nThe final optimal configurations are: $\\gamma = 2$ , $d=20$ , $\\eta =1E{-5}$ , $\\lambda _s = 0.01$ , $\\lambda _t = 0.1$ , and $L_1$ distance on WN18; $\\gamma =2$ , $d=100$ , $\\eta =1E{-5}$ , $\\lambda _s = 0.01$ , $d=20$0 , and $d=20$1 distance on FB15K.\nExperimental results on both WN18 and FB15k are shown in Table 2 , where we use “Jointly(CBOW)”, “Jointly(LSTM)” and “Jointly(A-LSTM)” to represent our jointly encoding models with CBOW, LSTM and attentive LSTM text encoders. Our baseline is TransE since that the score function of our models is based on TransE.\nFrom the results, we observe that proposed models surpass the baseline, TransE, on all metrics, which indicates that knowledge representation can benefit greatly from text description.\nOn WN18, the reason why “Jointly(A-LSTM)” is slightly worse than “Jointly(LSTM)” is probably because the number of relations is limited. Therefore, the attention mechanism does not have obvious advantage. On FB15K, “Jointly(A-LSTM)” achieves the best performance and is significantly higher than baseline methods on mean rank.\nAlthough the Hits@10 of our models are worse than the best state-of-the-art method, TransD, it is worth noticing that the score function of our models is based on TransE, not TransD. Our models are compatible with other state-of-the-art knowledge embedding models. We believe that our model can be further improved by adopting the score functions of other state-of-the-art methods, such as TransD.\nBesides, textual information largely alleviates the issue of sparsity and our model achieves substantial improvement on Mean Rank comparing with TransD. However, textual information may slightly degrade the representation of frequent entities which have been well-trained. This may be another reason why our Hits@10 is worse than TransD which only utilizes structural information.\nFor the comparison of Hits@10 of different kinds of relations, we categorized the relationships according to the cardinalities of their head and tail arguments into four classes: 1-to-1, 1-to-many, many-to-1, many-to-many. Mapping properties of relations follows the same rules in BIBREF2 .\nTable 3 shows the detailed results by mapping properties of relations on FB15k. We can see that our models outperform baseline TransE in all types of relations (1-to-1, 1-to-N, N-to-1 and N-to-N), especially when (1) predicting “1-to-1” relations and (2) predicting the 1 side for “1-to-N” and “N-to-1” relations.\nTo get more insights into how the joint representation is influenced by the structure and text information. We observe the activations of gates, which control the balance between two sources of information, to understand the behavior of neurons. We sort the entities by their frequencies and divide them into 50 equal-size groups of different frequencies, and average the values of all gates in each group.\nFigure 3 gives the average of gates in ten groups from high- to low-frequency. We observe that the text information play more important role for the low-frequency entities.\nFrom the results, we observe that proposed models surpass the baseline, TransE, on all metrics, which indicates that knowledge representation can benefit greatly from text description.",

For me, the interesting part, often overlooked, is the preamble that a well regulated militia is necessary for the security of a free State.  This may have been relevant to all people in the 18th century.  Today, we already have that \"militia\".  All law officers and soldiers make up that militia.  The armed forces are well regulated and are tasked with protecting the nation.  We, the US, have the best military in the world.  So it is not necessary for any Tom, Dick, or Harry, without training or national perspective, to take up arms.  Especially when the process itself is getting more unregulated.

While BIBREF0 used Lead-3 as an extractive baseline, in our data sentence order doesn't matter as reflections are independent. We thus use a similar in concept baseline: randomly select N reflections. Since the baseline is random we report the average result of 100 runs. Following BIBREF5, we compare results to MEAD BIBREF20 and to BIBREF5's extractive phrase-based model. Since these models extracted 5 phrases as extractive summary, we use N=5 for our three extractive baselines. Additionally we compare to running only the extractive part of Fast-RL.\nDomain Transfer (for testing H2, H5).\nTo observe the impact of using out-of-domain (news) data for pretraining to compensate for low resource in-domain (reflection) data, we train 3 variants of PG-net: model training on CNN/DM; model training on reflections; and model training on CNN/DM then tuning using reflections. Table TABREF11 shows example summaries generated by the three variants of PG-net for a CS document. For all experiments where reflections are used for training/tuning, we train using a leave one course out approach (i.e, in each fold, three courses are used for training and the remaining course for testing). If the experiment involves tuning a combined dictionary of CNN/DM and reflections is used to avoid domain mismatch. To tune model parameters, the best number of steps for training, the learning rate, etc., a randomly selected 50% of the training data is used for validation. We choose the parameters that maximize ROUGE scores over this validation set.\nTo implement PG-net we use OpenNMT BIBREF21 with the original set of parameters. The out-of-domain model is trained for 100k steps using the CNN/DM dataset. Following base model training, we tune the model by training it using student reflections. The tuning is done by lowering the LR from 0.15 to 0.1 and training the model for additional 500 steps. The in-domain model is trained only using reflections. We use the same model architecture as above and train the model for 20k steps using adagrad and LR of 0.15.\nSynthesis Baseline (for testing H3, H4). Following BIBREF12, we developed a data synthesis baseline using word replacement via WordNet. The baseline iterates over all words in a summary. If word $X$ has $N$ synonyms in WordNet, the model creates $N$ new versions of the summary and corresponding reflections by replacing the word $X$ with each of the $N$ synonyms.\nTemplate Synthesis Model (for testing H4, H5). To synthesize summaries, we use the same leave one course out approach. For each course, we use the data from the other three courses to train the rewriting module and tune the scoring language model. We can also use the summaries from CNN/DM data as additional samples to further train the rewriting module. We then start synthesizing data using that training data as input. First templates are constructed. The templates are then clustered into 8 clusters. We decided to use 8 to avoid clustering templates from POI with MP, as the templates from both prompts would contain very different supporting words. We also wanted to avoid a high level of dissimilarity within each cluster, and allow some diversity. Following the clustering, the rewriting model produces candidate summaries for each human summary. The rewriting model is another PG-net with the same exact parameters. After producing the candidate summaries, a language model is used to score them. The language model is a single layer LSTM language model trained on 36K sentences from Wikipedia and fine tuned using student reflections. In this work we decided to pick only the highest 3 scored candidate summaries as synthetic data, to avoid adding ill-formed summaries to the training data. Since we are adding $N$ synthetic summaries for each set of reflections, that means we are essentially duplicating the size of our original reflection training data by $N$, which is 3 in our case. Table TABREF11 shows a human summary, the keywords extracted, then the output of injecting keywords in a different template using rewriting.\nTemplate-based Summarization (for testing H6). While the proposed template-based model was intended for data synthesis, with minor modification it can be adapted for summarization itself. Because the modifications introduce few parameters, the model is suitable for small datasets. Recall that for data synthesis, the input to the template method is a summary. Since for summarization the input instead is a set of reflections, we perform keyword extraction over the set of reflections. We then add an extra logistic regression classifier that uses the set of reflections as input and predicts a cluster of templates constructed from other courses. Using the keywords and the predicted cluster of templates, we use the same rewriting model to produce candidate summaries. The last step in the pipeline is scoring. In data synthesis, a reference summary is used for scoring; however, in summarization we don't have such a reference. To score the candidate summaries, the model only uses the language model and produces the candidate with the highest score.\nOur experimental designs address the following hypotheses: Hypothesis 1 (H1) : Training complex abstractive models with limited in-domain or large quantities of out-of-domain data won’t be enough to outperform extractive baselines. Hypothesis 2 (H2) : Domain transfer helps abstractive models even if in-domain and out-of-domain data are very different and the amount of in-domain data is very small.

I wondered what was out there and if I would ever get to see it.  I had just met this world and wanted to learn so much more.  But I was only 3 inches tall and couldn't see much of anything.  So I waited.\n\nAs I got taller, the days began to feel shorter.  My favorite part of the day was feeling the wind blow through my newly acquired canopy of needles.

One day I'll be one of them.\n\nDays turned to weeks, and weeks turned into years, and it all felt so rushed that I could hardly keep track of the changing world around me.

What a strange feeling.  One cloudy day, I saw a lightning bolt strike a hilltop.  Soon enough, bright orange flames erupted across the horizon.  What a peculiar sight.  What began as a curiosity soon became terror as the fire rushed closer to my area of the woods.  I could feel the warm wind on my face as the fire grew more prominent.  Mercifully, the dark clouds hanging overhead opened up to a torrential downpour.  Cold pelting raindrops replaced the warm breeze, night fell over the mountain, and the forest breathed a sigh of relief.  \n\nI awoke to a strange sight when the sun returned the next day.

        "evidence": "The Dunning–Kruger effect is a cognitive bias whereby people with low ability, expertise, or experience regarding a certain type of task or area of knowledge tend to overestimate their ability or knowledge. Some researchers also include the opposite effect for high performers: their tendency to underestimate their skills. In popular culture, the Dunning–Kruger effect is often misunderstood as a claim about general overconfidence of people with low intelligence instead of specific overconfidence of people unskilled at a particular task.\n\nThe Dunning–Kruger effect is usually measured by comparing self-assessment with a measure of objective performance. For example, the participants in a study may be asked to complete a quiz and then estimate how well they performed. This subjective assessment is then compared with how well they actually performed. This can happen in either relative or absolute terms, i.e., in comparison with one's peer group as the percentage of peers outperformed or in comparison with objective standards as the number of questions answered correctly. The Dunning–Kruger effect appears in both cases, but is more pronounced in relative terms; the bottom quartile of performers tend to see themselves as being part of the top two quartiles. The initial study was published by David Dunning and Justin Kruger in 1999. It focused on logical reasoning, grammar, and social skills. Since then various other studies have been conducted across a wide range of tasks, including skills from fields such as business, politics, medicine, driving, aviation, spatial memory, examinations in school, and literacy.\n\nMany models have been suggested to explain the Dunning-Kruger effect's underlying causes. The original model by Dunning and Kruger holds that a lack of metacognitive abilities is responsible. This interpretation is based on the idea that poor performers have not yet acquired the ability to distinguish between good and bad performances. They tend to overrate themselves because they do not see the qualitative difference between their performances and the performances of others. This has also been termed the \"dual-burden account\" since the lack of skill is paired with the ignorance of this deficiency. Some researchers include the metacognitive component as part of the definition of the Dunning–Kruger effect and not just as an explanation distinct from it. Various researchers have criticized the metacognitive model and proposed alternative explanations. According to the statistical model, a statistical effect known as regression toward the mean together with the cognitive bias known as the better-than-average effect are responsible for the empirical findings. The rational model holds that overly positive prior beliefs about one's skills are the source of false self-assessment. Another explanation claims that self-assessment is more difficult and error-prone for low performers because many of them have very similar skill levels. Another model sees lack of incentive to give accurate self-assessments as the source of error.\n\nThe Dunning–Kruger effect has been described as relevant for various practical matters, but disagreements exist about the magnitude of its influence. Inaccurate self-assessment can lead people to make bad decisions, such as choosing a career for which they are unfit or engaging in dangerous behavior. It may also inhibit the affected from addressing their shortcomings to improve themselves. In some cases, the associated overconfidence may have positive side effects, like increasing motivation and energy.",
        "answer": "The Dunning-Kruger effect refers to the tendency for people to over-estimate their ability to perform a particular task, particular if they are low-skilled at that task.  Related research suggests that the converse is also true; high-skills performers tend to underestimate their ability.  The effect was validated through a number of studies covering a range of skills, though the cause of the effect is still a matter of debate.  Similarly, the practical implications of the effect is debatable, as over-confidence stemming from an inaccurate self-assessments can have positive and negative impacts.",

QE research has grown increasingly popular due to the improved quality of MT systems, and potential for reductions in post-editing time and the corresponding savings in labor costs BIBREF2 , BIBREF3 . QE can be performed on multiple granularities, including at word level, sentence level, or document level. In this paper, we focus on quality estimation at word level, which is framed as the task of performing binary classification of translated tokens, assigning “OK” or “BAD” labels.\nEarly work on this problem mainly focused on hand-crafted features with simple regression/classification models BIBREF4 , BIBREF5 . Recent papers have demonstrated that utilizing recurrent neural networks (RNN) can result in large gains in QE performance BIBREF6 . However, these approaches encode the context of the target word by merely concatenating its left and right context words, giving them limited ability to control the interaction between the local context and the target word.\nIn this paper, we propose a neural architecture, Context Encoding Quality Estimation (CEQE), for better encoding of context in word-level QE. Specifically, we leverage the power of both (1) convolution modules that automatically learn local patterns of surrounding words, and (2) hand-crafted features that allow the model to make more robust predictions in the face of a paucity of labeled data. Moreover, we further utilize stacked recurrent neural networks to capture the long-term dependencies and global context information from the whole sentence.\nWe tested our model on the official benchmark of the WMT18 word-level QE task.

        "answer": "Using a word-based and character-based text classification model on benchmark classification tasks: sentiment classification and news categorization.",
        "evidence": "Adversarial examples are generally minimal perturbations applied to the input data in an effort to expose the regions of the input space where a trained model performs poorly. Prior works BIBREF0, BIBREF1 have demonstrated the ability of an adversary to evade state-of-the-art classifiers by carefully crafting attack examples which can be even imperceptible to humans. Following such approaches, there has been a number of techniques aimed at generating adversarial examples BIBREF2, BIBREF3. Depending on the degree of access to the target model, an adversary may operate in one of the two different settings: (a) black-box setting, where an adversary doesn't have access to target model's internal architecture or its parameters, (b) white-box setting, where an adversary has access to the target model, its parameters, and input feature representations. In both these settings, the adversary cannot alter the training data or the target model itself. Depending on the purpose of the adversary, adversarial attacks can be categorized as (a) targeted attack and (b) non-targeted attack. In a targeted attack, the output category of a generated example is intentionally controlled to a specific target category with limited change in semantic information. While a non-targeted attack doesn't care about the category of misclassified results.\nMost of the prior work has focused on image classification models where adversarial examples are obtained by introducing imperceptible changes to pixel values through optimization techniques BIBREF4, BIBREF5. However, generating natural language adversarial examples can be challenging mainly due to the discrete nature of text samples. Continuous data like image or speech is much more tolerant to perturbations compared to text BIBREF6. In textual domain, even a small perturbation is clearly perceptible and can completely change the semantics of the text. Another challenge for generating adversarial examples relates to identifying salient areas of the text where a perturbation can be applied successfully to fool the target classifier. In addition to fooling the target classifier, the adversary is designed with different constraints depending on the task and its motivations BIBREF7. In our work, we focus on constraining our adversary to craft examples with semantic preservation and minimum perturbations to the input text.\nGiven different settings of the adversary, there are other works that have designed attacks in “gray-box” settings BIBREF8, BIBREF9, BIBREF10. However, the definitions of “gray-box” attacks are quite different in each of these approaches. In this paper, we focus on “black-box” setting where we assume that the adversary possesses a limited set of labeled data, which is different from the target's training data, and also has an oracle access to the system, i.e., one can query the target classifier with any input and get its corresponding predictions. We propose an effective technique to generate adversarial examples in a black-box setting. We develop an Adversarial Example Generator (AEG) model that uses a reinforcement learning framing to generate adversarial examples. We evaluate our models using a word-based BIBREF11 and character-based BIBREF12 text classification model on benchmark classification tasks: sentiment classification and news categorization. The adversarial sequences generated are able to effectively fool the classifiers without changing the semantics of the text. Our contributions are as follows:\nWe propose a black-box non-targeted attack strategy by combining ideas of substitute network and adversarial example generation. We formulate it as a reinforcement learning task.\nWe introduce an encoder-decoder that operates over words and characters of an input text and empowers the model to introduce word and character-level perturbations.\nWe adopt a self-critical sequence training technique to train our model to generate examples that can fool or increase the probability of misclassification in text classifiers.\nWe evaluate our models on two different datasets associated with two different tasks: IMDB sentiment classification and AG's news categorization task. We run ablation studies on various components of the model and provide insights into decisions of our model.\nWe evaluate our models using a word-based and character-based text classification model on benchmark classification tasks: sentiment classification and news categorization.",

        "question": "Given these paragraphs about Asperger syndrome, what are typical interventions that help improve the person's ability to function in the everyday world?",
        "evidence": "Asperger syndrome (AS), also known as Asperger's, is a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behaviour and interests. The syndrome is no longer recognised as a diagnosis in itself, having been merged with other conditions into autism spectrum disorder (ASD). It was considered to differ from other diagnoses that were merged into ASD by relatively unimpaired spoken language and intelligence.\n\nThe syndrome was named after the Austrian pediatrician Hans Asperger, who, in 1944, described children in his care who struggled to form friendships, did not understand others' gestures or feelings, engaged in one-sided conversations about their favourite interests, and were clumsy. In 1994, the diagnosis of Asperger's was included in the fourth edition (DSM-IV) of the American Diagnostic and Statistical Manual of Mental Disorders; however, with the publication of DSM-5 in 2013 the syndrome was removed, and the symptoms are now included within autism spectrum disorder along with classic autism and pervasive developmental disorder not otherwise specified (PDD-NOS). It was similarly merged into autism spectrum disorder in the International Classification of Diseases (ICD-11) as of 2021.\n\nThe exact cause of Asperger's is poorly understood. While it has high heritability, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role. Brain imaging has not identified a common underlying condition. There is no single treatment, and the UK's National Health Service (NHS) guidelines suggest that 'treatment' of any form of autism should not be a goal, since autism is not 'a disease that can be removed or cured'. According to the Royal College of Psychiatrists, while co-occurring conditions might require treatment, 'management of autism itself is chiefly about the provision of the education, training and social support/care required to improve the person's ability to function in the everyday world'. The effectiveness of particular interventions for autism is supported by only limited data. Interventions may include social skills training, cognitive behavioral therapy, physical therapy, speech therapy, parent training, and medications for associated problems, such as mood or anxiety. Autistic characteristics tend to become less obvious in adulthood, but social and communication difficulties usually persist.\n\nhttps://en.wikipedia.org/wiki/Asperger_syndrome",

We made sure that our guidelines were compatible with those of OffensEval2019. The annotator carried out all annotation. Tweets were given one or more of the following four labels: offensive, vulgar, hate speech, or clean. Since the offensive label covers both vulgar and hate speech and vulgarity and hate speech are not mutually exclusive, a tweet can be just offensive or offensive and vulgar and/or hate speech. The annotation adhered to the following guidelines:\nOffensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as:\nDirect threats or incitement, ex: احرقوا> مقرات المعارضة> (“AHrqwA mqrAt AlmEArDp” – “burn the headquarters of the opposition”) and هذا المنافق يجب قتله> (“h*A AlmnAfq yjb qtlh” – “this hypocrite needs to be killed”).\nInsults and expressions of contempt, which include: Animal analogy, ex: يا كلب> (“yA klb” – “O dog”) and كل تبن> (“kl tbn” – “eat hay”).; Insult to family members, ex: يا روح أمك> (“yA rwH Amk” – “O mother's soul”); Sexually-related insults, ex: يا ديوث> (“yA dywv” – “O person without envy”); Damnation, ex: الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”); and Attacks on morals and ethics, ex: يا كاذب> (“yA kA*b” – “O liar”)\nVulgar tweets are a subset of offensive tweets and contain profanity, such as mentions of private parts or sexual-related acts or references.\nHate speech tweets, a subset of offensive tweets containing offensive language targeting group based on common characteristics such as: Race, ex: يا زنجي> (“yA znjy” – “O negro”); Ethnicity, ex. الفرس الأنجاس> (“Alfrs AlAnjAs” – “Impure Persians”); Group or party, ex: أبوك شيوعي> (“Abwk $ywEy” – “your father is communist”); and Religion, ex: دينك القذر> (“dynk Alq*r” – “your filthy religion”).\nClean tweets do not contain vulgar or offensive language. We noticed that some tweets have some offensive words, but the whole tweet should not be considered as offensive due to the intention of users. This suggests that normal string match without considering contexts will fail in some cases. Examples of such ambiguous cases include: Humor, ex: يا عدوة الفرحة ههه> (“yA Edwp AlfrHp hhh” – “O enemy of happiness hahaha”); Advice, ex: لا تقل لصاحبك يا خنزير> (“lA tql lSAHbk yA xnzyr” – “don't say to your friend: You are a pig”); Condition, ex: إذا عارضتهم يقولون يا عميل> (“A*A EArDthm yqwlwn yA Emyl” – “if you disagree with them they will say: You are an agent”); Condemnation, ex: لماذا نسب بقول: يا بقرة؟> (“lmA*A nsb bqwl: yA bqrp?” – “Why do we insult others by saying: O cow?”); Self offense, ex: تعبت من لساني القذر> (“tEbt mn lsAny Alq*r” – “I am tired of my dirty tongue”); Non-human target, ex: يا بنت المجنونة يا كورة> (“yA bnt Almjnwnp yA kwrp” – “O daughter of the crazy one O football”); and Quotation from a movies or a story, ex: تاني يا زكي! تاني يا فاشل> (“tAny yA zky! tAny yA fA$l” – “again O Zaky! again O loser”). For other ambiguous cases, the annotator searched Twitter to find how actual users used expressions.\nTable TABREF11 shows the distribution of the annotated tweets. There are 1,915 offensive tweets, including 225 vulgar tweet and 506 hate speech tweets, and 8,085 clean tweets. To validate the quality of annotation, a random sample of 100 tweets from the data, containing 50 offensive and 50 clean tweets, was given to additional three annotators. We calculated the Inter-Annotator Agreement between the annotators using Fleiss’s Kappa coefficient BIBREF23. The Kappa score was 0.92 indicating high quality annotation and agreement.\nCLEAN (CLN): Clean tweets do not contain vulgar or offensive language.",

A statistical language model estimates the probability of a sequence of words or an upcoming word. An N-gram is a contiguous sequence of N words: a unigram is a single word, a bigram is a two-word sequence, and a trigram is a three-word sequence. For example, in the tweet\ntears in Ramen #SingleLifeIn3Words\n“tears”, “in”, “Ramen” and “#SingleLifeIn3Words” are unigrams; “tears in”, “in Ramen” and “Ramen #SingleLifeIn3Words” are bigrams and “tears in Ramen” and “in Ramen #SingleLifeIn3Words” are trigrams.\nAn N-gram model can predict the next word from a sequence of N-1 previous words. A trigram Language Model (LM) predicts the conditional probability of the next word using the following approximation: DISPLAYFORM0 \nThe assumption that the probability of a word depends only on a small number of previous words is called a Markov assumption BIBREF8 . Given this assumption the probability of a sentence can be estimated as follows: DISPLAYFORM0 \nIn a study on how phrasing affects memorability, BIBREF9 take a language model approach to measure the distinctiveness of memorable movie quotes. They do this by evaluating a quote with respect to a “common language” model built from the newswire sections of the Brown corpus BIBREF10 . They find that movie quotes which are less like “common language” are more distinctive and therefore more memorable. The intuition behind our approach is that humor should in some way be memorable or distinct, and so tweets that diverge from a “common language” model would be expected to be funnier.\nIn order to evaluate how funny a tweet is, we train language models on two datasets: the tweet data and the news data. Tweets that are more probable according to the tweet data language model are ranked as being funnier. However, tweets that have a lower probability according to the news language model are considered the funnier since they are the least like the (unfunny) news corpus. We relied on both bigrams and trigrams when training our models.\nWe use KenLM BIBREF11 as our language modeling tool. Language models are estimated using modified Kneser-Ney smoothing without pruning. KenLM also implements a back-off technique so if an N-gram is not found, KenLM applies the lower order N-gram's probability along with its back-off weights.\nWe relied on both bigrams and trigrams when training our models.

The results are then compared with the original MS-COCO English categorized with sportball category.\nOverall, we can see that English set only out-performed Vietnamese ones in BLEU-1 metric, rather, the Vietnamese sets performing well basing on BLEU-2 to BLEU-4, especially CIDEr scores. On the other hand, when UIT-ViIC is compared with the dataset having captions translated by Google, the evaluation results and the output examples suggest that Google Translation service is able to perform acceptablly even though most translated captions are not perfectly natural and linguistically friendly. As a results, we proved that manually written captions for Vietnamese dataset is currently prefered.\nFor future improvements, extending the UIT-ViIC's cateogry into all types of sport to verify how the dataset's size and category affect the Image Captioning models' performance is considered as our highest priority. Moreover, the human resources for dataset construction will be expanded.

        "evidence": "The ideological leanings of a person within the left-right political spectrum are often reflected by how one feels about different topics and by means of preferences among various choices on particular issues. For example, a left-leaning person would prefer nationalization and state control of public services (such as healthcare) where privatization would be often preferred by people that lean towards the right. Likewise, a left-leaning person would often be supportive of immigration and will often talk about immigration in a positive manner citing examples of benefits of immigration on a country's economy. A right-leaning person, on the other hand, will often have a negative opinion about immigration.\nMost of the existing works on political ideology detection from text have focused on utilizing bag-of-words and other syntactic features to capture variations in language use BIBREF0 , BIBREF1 , BIBREF2 . We propose an alternative mechanism for political ideology detection based on sentiment analysis. We posit that adherents of a political ideology generally have similar sentiment toward specific topics (for example, right wing followers are often positive towards free markets, lower tax rates, etc.) and thus, a political ideology can be represented by a characteristic sentiment distribution over different topics (Section SECREF3 ). This topic-specific sentiment representation of a political ideology can then be used for automatic ideology detection by comparing the topic-specific sentiments as expressed by the content in a document (news article, magazine article, collection of social media posts by a user, utterances in a conversation, etc.).\nIn order to validate our hypothesis, we consider exploiting the sentiment information towards topics from archives of political debates to build a model for identifying political orientation of speakers as one of right or left leaning, which corresponds to republicans and democrats respectively, within the context of US politics. This is inspired by our observation that the political leanings of debators are often expressed in debates by way of speakers' sentiments towards particular topics. Parliamentary or Senate debates often bring the ideological differences to the centre stage, though somewhat indirectly. Heated debates in such forums tend to focus on the choices proposed by the executive that are in sharp conflict with the preference structure of the opposition members. Due to this inherent tendency of parliamentary debates to focus on topics of disagreement, the sentiments exposited in debates hold valuable cues to identify the political orientation of the participants.\nWe develop a simple classification model that uses a topic-specific sentiment summarization for republican and democrat speeches separately. Initial results of experiments conducted using a widely used dataset of US Congress debates BIBREF3 are encouraging and show that this simple model compares well with classification models that employ state-of-the-art distributional text representations (Section SECREF4 ).\nIn order to validate our hypothesis, we consider exploiting the sentiment information towards topics from archives of political debates to build a model for identifying political orientation of speakers as one of right or left leaning, which corresponds to republicans and democrats respectively, within the context of US politics.",

Eucalyptus oil finds many uses like in fuels, fragrances, insect repellence and antimicrobial activity.

Over this dataset, we compare the methodology suggested here to those reported by BIBREF1, BIBREF4. As the latter report overall accuracy of their binary prediction, we convert our controversiality estimates to a binary classification by classifying the higher-scored half as controversial, and the lower half as non-controversial.\nDataset II is based on a more recent version of the Wikipedia list of controversial issues (May 2017). As positive examples we take, from this list, all concepts which appear more than 50 times in Wikipedia. This leaves 608 controversial Wikipedia concepts. For negative examples, we follow BIBREF1, BIBREF4 and select a like number of concepts at random. Here too, since each concept only has a binary label, we convert our estimation into a binary classification, and report accuracy.\nDataset III is extracted from 3561 concepts whose Wikipedia pages are under edit protection, assuming that many of them are likely to be controversial. They were then crowd-annotated, with 10 or more annotators per concept. The annotation instructions were: “Given a topic and its description on Wikipedia, mark if this is a topic that people are likely to argue about.”. Average pairwise kappa agreement on this task was 0.532. Annotations were normalized to controversiality scores on an integer scale of 0 - 10. We used this dataset for testing the models trained on Dataset I.\nIn all datasets, to obtain the sentence-level context of the concepts (positive and negative), we randomly select two equal-sized sets of Wikipedia sentences, that explicitly reference these concepts – i.e., that contain a hyperlink to the article titled by the concept. Importantly, in each sentence we mask the words that reference the concept – i.e., the surface form of the hyperlink leading to the concept – by a fixed, singular token, thus focusing solely on the context within which the concepts are mentioned.\nDataset I consists of 480 concepts previously analyzed in Dori-Hacohen et al.

But somewhat surprisingly, the paragraph-level models achieve noticeable performance gains on short paragraphs (with 2 or 3 DUs) as well.

        "answer": "Instead of a quadratic number of independent attention layers, however, one single attention mechanism is integrated into their NMT, performing an affine transformation between the hidden layer of m source languages and that one of n target languages.",
        "evidence": "By extending the solution of sequence-to-sequence modeling using encoder-decoder architectures to multi-task learning, Luong2016 managed to achieve better performance on some INLINEFORM0 tasks such as translation, parsing and image captioning compared to individual tasks. Specifically in translation, the work utilizes multiple encoders to translate from multiple languages, and multiple decoders to translate to multiple languages. In this view of multilingual translation, each language in source or target side is modeled by one encoder or decoder, depending on the side of the translation. Due to the natural diversity between two tasks in that multi-task learning scenario, e.g. translation and parsing, it could not feature the attention mechanism although it has proven its effectiveness in NMT. There exists two directions which proposed for multilingual translation scenarios where they leverage the attention mechanism. The first one is indicated in the work from BIBREF8 , where it introduce an one-to-many multilingual NMT system to translates from one source language into multiple target languages. Having one source language, the attention mechanism is then handed over to the corresponding decoder. The objective function is changed to adapt to multilingual settings. In testing time, the parameters specific to a desired language pair are used to perform the translation.\nFirat2016 proposed another approach which genuinely delivers attention-based NMT to multilingual translation. As in BIBREF9 , their approach utilizes one encoder per source language and one decoder per target language for many-to-many translation tasks. Instead of a quadratic number of independent attention layers, however, one single attention mechanism is integrated into their NMT, performing an affine transformation between the hidden layer of INLINEFORM0 source languages and that one of INLINEFORM1 target languages. It is required to change their architecture to accomodate such a complicated shared attention mechanism.\nIn a separate effort to achieve multilingual NMT, the work of Zoph2016 leverages available parallel data from other language pairs to help reducing possible ambiguities in the translation process into a single target language. They employed the multi-source attention-based NMT in a way that only one attention mechanism is required despite having multiple encoders. To achieve this, the outputs of the encoders were combined before feeding to the attention layer. They implemented two types of encoder combination; One is adding a non-linear layer on the concatenation of the encoders' hidden states. The other is using a variant of LSTM taking the respective gate values from the individual LSTM units of the encoders. As a result, the combined hidden states contain information from both encoders , thus encode the common semantic of the two source languages.\nFirat et al. (2016) proposed another approach which genuinely delivers attention-based NMT to multilingual translation. As in (Luong et al., 2016), their approach utilizes one encoder per source language and one decoder per target language for many-to-many translation tasks.

        "evidence": "We created a new dataset called CW-USPD-2016 (check-worthiness in the US presidential debates 2016) for finding check-worthy claims in context. In particular, we used four transcripts of the 2016 US election: one vice-presidential and three presidential debates. For each debate, we used the publicly-available manual analysis about it from nine reputable fact-checking sources, as shown in Table TABREF7. This could include not just a statement about factuality, but any free text that journalists decided to add, e.g., links to biographies or behavioral analysis of the opponents and moderators. We converted this to binary annotation about whether a particular sentence was annotated for factuality by a given source. Whenever one or more annotations were about part of a sentence, we selected the entire sentence, and when an annotation spanned over multiple sentences, we selected each of them.\nUltimately, we ended up with a dataset of four debates, with a total of 5,415 sentences. The agreement between the sources was low as Table TABREF8 shows: only one sentence was selected by all nine sources, 57 sentences by at least five, 197 by at least three, 388 by at least two, and 880 by at least one. The reason for this is that the different media aimed at annotating sentences according to their own editorial line, rather than trying to be exhaustive in any way. This suggests that the task of predicting which sentence would contain check-worthy claims will be challenging. Thus, below we focus on a ranking task rather than on absolute predictions. Moreover, we predict which sentence would be selected (i) by at least one of the media, or (ii) by a specific medium.\nNote that the investigative journalists did not select the check-worthy claims in isolation. Our analysis shows that these include claims that were highly disputed during the debate, that were relevant to the topic introduced by the moderator, etc. We will make use of these contextual dependencies below, which is something that was not previously tried in related work.\nUltimately, we ended up with a dataset of four debates, with a total of 5,415 sentences.

        "evidence": "Word embeddings are representations of words in numerical form, as vectors of typically several hundred dimensions. The vectors are used as an input to machine learning models; for complex language processing tasks these are typically deep neural networks. The embedding vectors are obtained from specialized learning tasks, based on neural networks, e.g., word2vec BIBREF0, GloVe BIBREF1, FastText BIBREF2, ELMo BIBREF3, and BERT BIBREF4. For training, the embeddings algorithms use large monolingual corpora that encode important information about word meaning as distances between vectors. In order to enable downstream machine learning on text understanding tasks, the embeddings shall preserve semantic relations between words, and this is true even across languages.\nProbably the best known word embeddings are produced by the word2vec method BIBREF5. The problem with word2vec embeddings is their failure to express polysemous words. During training of an embedding, all senses of a given word (e.g., paper as a material, as a newspaper, as a scientific work, and as an exam) contribute relevant information in proportion to their frequency in the training corpus. This causes the final vector to be placed somewhere in the weighted middle of all words' meanings. Consequently, rare meanings of words are poorly expressed with word2vec and the resulting vectors do not offer good semantic representations. For example, none of the 50 closest vectors of the word paper is related to science.\nThe idea of contextual embeddings is to generate a different vector for each context a word appears in and the context is typically defined sentence-wise. To a large extent, this solves the problems with word polysemy, i.e. the context of a sentence is typically enough to disambiguate different meanings of a word for humans and so it is for the learning algorithms. In this work, we describe high-quality models for contextual embeddings, called ELMo BIBREF3, precomputed for seven morphologically rich, less-resourced languages: Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish. ELMo is one of the most successful approaches to contextual word embeddings. At time of its creation, ELMo has been shown to outperform previous word embeddings BIBREF3 like word2vec and GloVe on many NLP tasks, e.g., question answering, named entity extraction, sentiment analysis, textual entailment, semantic role labeling, and coreference resolution.\nThis report is split into further five sections. In section SECREF2, we describe the contextual embeddings ELMo. In Section SECREF3, we describe the datasets used and in Section SECREF4 we describe preprocessing and training of the embeddings.

        "evidence": "Social media is a very popular way for people to express their opinions publicly and to interact with others online. In aggregation, social media can provide a reflection of public sentiment on various events. Unfortunately, many users engaging online, either on social media, forums or blogs, will often have the risk of being targeted or harassed via abusive language, which may severely impact their online experience and the community in general. The existence of social networking services creates the need for detecting user-generated hateful messages prior to publication. All published text that is used to express hatred towards some particular group with the intention to humiliate its members is considered a hateful message.\nAlthough hate speech is protected under the free speech provisions in the United States, there are other countries, such as Canada, France, United Kingdom, and Germany, where there are laws prohibiting it as being promoting violence or social disorder. Social media services such as Facebook and Twitter have been criticized for not having done enough to prohibit the use of their services for attacking people belonging to some specific race, minority etc. BIBREF0 . They have announced though that they would seek to battle against racism and xenophobia BIBREF1 . Nevertheless, the current solutions deployed by them have attempted to address the problem with manual effort, relying on users to report offensive comments BIBREF2 . This not only requires a huge effort by human annotators, but it also has the risk of applying discrimination under subjective judgment. Moreover, a non-automated task by human annotators would have strong impact on system response times, since a computer-based solution can accomplish this task much faster than humans. The massive rise in the user-generated content in the above social media services, with manual filtering not being scalable, highlights the need for automating the process of on-line hate-speech detection.\nDespite the fact that the majority of the solutions for automated detection of offensive text rely on Natural Language Processing (NLP) approaches, there is lately a tendency towards employing pure machine learning techniques like neural networks for that task. NLP approaches have the drawback of being complex, and to a large extent dependent on the language used in the text. This provides a strong motivation for employing alternative machine learning models for the classification task. Moreover, the majority of the existing automated approaches depend on using pre-trained vectors (e.g. Glove, Word2Vec) as word embeddings to achieve good performance from the classification model. That makes the detection of hatred content unfeasible in cases where users have deliberately obfuscated their offensive terms with short slang words.\nThere is a plethora of unsupervised learning models in the existing literature to deal with hate-speech BIBREF3 , as well as in detecting the sentiment polarity in tweets BIBREF4 . At the same time, the supervised learning approaches have not been explored adequately so far. While the task of sentence classification seems similar to that of sentiment analysis; nevertheless, in hate-speech even negative sentiment could still provide useful insight. Our intuition is that the task of hate-speech detection can be further benefited by the incorporation of other sources of information to be used as features into a supervised learning model. A simple statistical analysis on an existing annotated dataset of tweets by BIBREF5 , can easily reveal the existence of significant correlation between the user tendency in expressing opinions that belong to some offensive class (Racism or Sexism), and the annotation labels associated with that class. More precisely, the correlation coefficient value that describes such user tendency was found to be 0.71 for racism in the above dataset, while that value reached as high as 0.76 for sexism. In our opinion, utilizing such user-oriented behavioural data for reinforcing an existing solution is feasible, because such information is retrieva2ble in real-world use-case scenarios like Twitter. This highlights the need to explore the user features more systematically to further improve the classification accuracy of a supervised learning system.\nOur approach employs a neural network solution composed of multiple Long-Short-Term-Memory (LSTM) based classifiers, and utilizes user behavioral characteristics such as the tendency towards racism or sexism to boost performance. Although our technique is not necessarily revolutionary in terms of the deep learning models used, we show in this paper that it is quite effective.\nOur main contributions are: INLINEFORM0 ) a deep learning architecture for text classification in terms of hateful content, which incorporates features derived form the users' behavioural data, INLINEFORM1 ) a language agnostic solution, due to no-use of pre-trained word embeddings, for detecting hate-speech, INLINEFORM2 ) an experimental evaluation of the model on a Twitter dataset, demonstrating the top performance achieved on the classification task. Special focus is given to investigating how the additional features concerning the users' tendency to utter hate-speech, as expressed by their previous history, could leverage the performance. To the best of our knowledge, there has not been done any previous study on exploring features related to the users tendency in hatred content that used a deep learning model.\nThe rest of the paper is organized as follows. In Section SECREF2 we describe the problem of hate speech in more detail, and we refer to the existing work in the field in Section SECREF3 . In Section SECREF4 we present our proposed model, while in Section SECREF5 we refer to the dataset used, the evaluation tests we performed and we discuss the results received. Finally, in Section SECREF6 we summarize our contributions and discuss the future work.\nOur approach employs a neural network solution composed of multiple Long-Short-Term-Memory (LSTM) based classifiers, and utilizes user behavioral characteristics such as the tendency towards racism or sexism to boost performance.",

        "evidence": "There has been a surge of recent interest in detecting human actions in videos. Work in this space has mainly focused on learning actions from articulated human pose BIBREF7 , BIBREF8 , BIBREF9 or mining spatial and temporal information from videos BIBREF10 , BIBREF11 . A number of resources have been produced, including Action Bank BIBREF12 , NTU RGB+D BIBREF13 , SBU Kinect Interaction BIBREF14 , and PKU-MMD BIBREF15 .\nMost research on video action detection has gathered video information for a set of pre-defined actions BIBREF2 , BIBREF16 , BIBREF1 , an approach known as explicit data gathering BIBREF0 . For instance, given an action such as “open door,” a system would identify videos that include a visual depiction of this action. While this approach is able to detect a specific set of actions, whose choice may be guided by downstream applications, it achieves high precision at the cost of low recall. In many cases, the set of predefined actions is small (e.g., 203 activity classes in BIBREF2 ), and for some actions, the number of visual depictions is very small.\nAn alternative approach is to start with a set of videos, and identify all the actions present in these videos BIBREF17 , BIBREF18 . This approach has been referred to as implicit data gathering, and it typically leads to the identification of a larger number of actions, possibly with a small number of examples per action.\nIn this paper, we use an implicit data gathering approach to label human activities in videos. To the best of our knowledge, we are the first to explore video action recognition using both transcribed audio and video information. We focus on the popular genre of lifestyle vlogs, which consist of videos of people demonstrating routine actions while verbally describing them. We use these videos to develop methods to identify if actions are visually present.\nThe paper makes three main contributions. First, we introduce a novel dataset consisting of 1,268 short video clips paired with sets of actions mentioned in the video transcripts, as well as manual annotations of whether the actions are visible or not. The dataset includes a total of 14,769 actions, 4,340 of which are visible. Second, we propose a set of strong baselines to determine whether an action is visible or not. Third, we introduce a multimodal neural architecture that combines information drawn from visual and linguistic clues, and show that it improves over models that rely on one modality at a time.\nBy making progress towards automatic action recognition, in addition to contributing to video understanding, this work has a number of important and exciting applications, including sports analytics BIBREF19 , human-computer interaction BIBREF20 , and automatic analysis of surveillance video footage BIBREF21 .\nThe paper is organized as follows. We begin by discussing related work, then describe our data collection and annotation process. We next overview our experimental set-up and introduce a multimodal method for identifying visible actions in videos. Finally, we discuss our results and conclude with general directions for future work.\nThird, we introduce a multimodal neural architecture that combines information drawn from visual and linguistic clues, and show that it improves over models that rely on one modality at a time.",

        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier. When we combine the two models, we achieve state-of-the-art results over 3/4 of our datasets.\nThis paper makes the following contributions:\nAll code and data associated with this research will be released on publication.\nOur visual model is based on fine-tuning an Inception V3 model (Szegedy et al. 2016) over visual renderings of documents, while our textual model is based on a hierarchical biLSTM.

We chose these features to capture fine to coarse-level temporal patterns of user activity. For example, commuting to work is a recurring pattern linked to a time of day, while paying bills is more closely tied to the day of the month, and vacations are more closely tied to the month.\nWe treated each of these bins as a word, so that we could use the same methods used in the last section to measure the similarity between the temporal activity patterns of pairs of accounts (this will also help greatly for creating the combined model, explained in the next section). In other word, the 12 bins in month were set to $w_1$ . . . $w_{12}$ , the 31 bins in day of month to $w_{13}$ . . . $w_{43}$ , the 7 bins in day of week to $w_{44}$ . . . $w_{50}$ , and the 24 bins in time were set to $w_{51}$ . . . $w_{74}$ .

        "evidence": "Our system comprises of following three steps:\nCloze generation: Most of the documents typically follow a template, they begin with an introduction that provides an overview and a brief summary for what is to follow. We assume such a structure while constructing our cloze style questions. When there is no clear demarcation, we treat the first $K\\%$ (hyperparameter, in our case 20%) of the document as the introduction. While noisy, this heuristic generates a large number of clozes given any corpus, which we found to be beneficial for semi-supervised learning despite the noise.\nWe use a standard NLP pipeline based on Stanford CoreNLP (for SQuAD, TrivaQA and PubMed) and the BANNER Named Entity Recognizer (only for PubMed articles) to identify entities and phrases. Assume that a document comprises of introduction sentences $\\lbrace q_1, q_2, ... q_n\\rbrace $ , and the remaining passages $\\lbrace p_1, p_2, .. p_m\\rbrace $ . Additionally, let's say that each sentence $q_i$ in introduction is composed of words $\\lbrace w_1, w_2, ... w_{l_{q_i}}\\rbrace $ , where $l_{q_i}$ is the length of $q_i$ . We consider a $\\text{match} (q_i, p_j)$ , if there is an exact string match of a sequence of words $\\lbrace w_k, w_{k+1}, .. w_{l_{q_i}}\\rbrace $ between the sentence $q_i$ and passage $p_j$ . If this sequence is either a noun phrase, verb phrase, adjective phrase or a named entity in $\\lbrace p_1, p_2, .. p_m\\rbrace $0 , as recognized by CoreNLP or BANNER, we select it as an answer span $\\lbrace p_1, p_2, .. p_m\\rbrace $1 . Additionally, we use $\\lbrace p_1, p_2, .. p_m\\rbrace $2 as the passage $\\lbrace p_1, p_2, .. p_m\\rbrace $3 and form a cloze question $\\lbrace p_1, p_2, .. p_m\\rbrace $4 from the answer bearing sentence $\\lbrace p_1, p_2, .. p_m\\rbrace $5 by replacing $\\lbrace p_1, p_2, .. p_m\\rbrace $6 with a placeholder. As a result, we obtain passage-question-answer ( $\\lbrace p_1, p_2, .. p_m\\rbrace $7 ) triples (Table 1 shows an example). As a post-processing step, we prune out $\\lbrace p_1, p_2, .. p_m\\rbrace $8 triples where the word overlap between the question (Q) and passage (P) is less than 2 words (after excluding the stop words).\nThe process relies on the fact that answer candidates from the introduction are likely to be discussed in detail in the remainder of the article. In effect, the cloze question from the introduction and the matching paragraph in the body forms a question and context passage pair. We create two cloze datasets, one each from Wikipedia corpus (for SQuAD and TriviaQA) and PUBMed academic papers (for the BioASQ challenge), consisting of 2.2M and 1M clozes respectively. From analyzing the cloze data manually, we were able to answer 76% times for the Wikipedia set and 80% times for the PUBMed set using the information in the passage. In most cases the cloze paraphrased the information in the passage, which we hypothesized to be a useful signal for the downstream QA task.\nWe also investigate the utility of forming subsets of the large cloze corpus, where we select the top passage-question-answer triples, based on the different criteria, like i) jaccard similarity of answer bearing sentence in introduction and the passage ii) the tf-idf scores of answer candidates and iii) the length of answer candidates. However, we empirically find that we were better off using the entire set rather than these subsets.\nPre-training: We make use of the generated cloze dataset to pre-train an expressive neural network designed for the task of reading comprehension. We work with two publicly available neural network models – the GA Reader BIBREF2 (to enable comparison with prior work) and BiDAF + Self-Attention (SA) model from BIBREF1 (which is among the best performing models on SQuAD and TriviaQA). After pretraining, the performance of BiDAF+SA on a dev set of the (Wikipedia) cloze questions is 0.58 F1 score and 0.55 Exact Match (EM) score. This implies that the cloze corpus is neither too easy, nor too difficult to answer.\nFine Tuning: We fine tune the pre-trained model, from the previous step, over a small set of labelled question-answer pairs. As we shall later see, this step is crucial, and it only requires a handful of labelled questions to achieve a significant proportion of the performance typically attained by training on tens of thousands of questions.\nPre-training: We make use of the generated cloze dataset to pre-train an expressive neural network designed for the task of reading comprehension. We work with two publicly available neural network models — the GA Reader (Dhingra et al., 2017) (to enable comparison with prior work) and BiDAF + Self-Attention (SA) model from Clark and Gardner (2017) (which is among the best performing models on SQuAD and TriviaQA).",

        "evidence": "Our work is related to three lines of research: Sequence labeling, Adversarial training, and Crowdsourcing.\nSequence labeling. NER is widely treated as a sequence labeling problem, by assigning a unique label over each sentential word BIBREF9 . Early studies on sequence labeling often use the models of HMM, MEMM, and CRF BIBREF10 based on manually-crafted discrete features, which can suffer the feature sparsity problem and require heavy feature engineering. Recently, neural network models have been successfully applied to sequence labeling BIBREF1 , BIBREF11 , BIBREF2 . Among these work, the model which uses Bi-LSTM for feature extraction and CRF for decoding has achieved state-of-the-art performances BIBREF11 , BIBREF2 , which is exploited as the baseline model in our work.\nAdversarial Training. Adversarial Networks have achieved great success in computer vision such as image generation BIBREF12 , BIBREF13 . In the NLP community, the method is mainly exploited under the settings of domain adaption BIBREF14 , BIBREF7 , cross-lingual BIBREF15 , BIBREF6 and multi-task learning BIBREF16 , BIBREF17 . All these settings involve the feature divergences between the training and test examples, and aim to learn invariant features across the divergences by an additional adversarial discriminator, such as domain discriminator. Our work is similar to these work but is applies on crowdsourcing learning, aiming to find invariant features among different crowdsourcing workers.\nCrowdsourcing. Most NLP tasks require a massive amount of labeled training data which are annotated by experts. However, hiring experts is costly and non-scalable, both in terms of time and money. Instead, crowdsourcing is another solution to obtain labeled data at a lower cost but with relative lower quality than those from experts. BIBREF18 snow2008cheap collected labeled results for several NLP tasks from Amazon Mechanical Turk and demonstrated that non-experts annotations were quite useful for training new systems. In recent years, a series of work have focused on how to use crowdsourcing data efficiently in tasks such as classification BIBREF19 , BIBREF20 , and compare quality of crowd and expert labels BIBREF21 .\nIn sequence labeling tasks, BIBREF22 dredze2009sequence viewed this task as a multi-label problem while BIBREF3 rodrigues2014sequence took workers identities into account by assuming that each sentential word was tagged correctly by one of the crowdsourcing workers and proposed a CRF-based model with multiple annotators. BIBREF4 nguyen2017aggregating introduced a crowd representation in which the crowd vectors were added into the LSTM-CRF model at train time, but ignored them at test time. In this paper, we apply adversarial training on crowd annotations on Chinese NER in new domains, and achieve better performances than previous studies on crowdsourcing learning.\nAmong these work, the model which uses Bi-LSTM for feature extraction and CRF for decoding has achieved state-of-the-art performances (Huang, Xu, and Yu 2015; Lample et al. 2016), which is exploited as the baseline model in our work.",

New data is generated on a daily basis, coded according to the CAMEO event ontology, with an average of 2,200 events generated per day. The full dataset examined here contains 254,060 total events spread across 102 days of generated data. Based on publicly available information, the project also makes use of the most up-to-date actor dictionaries of any available machine-coded event dataset.\nThe dataset currently contains 27 columns: “EventID”, “Date”, “Year”, “Month”, “Day”, “SourceActorFull”, “SourceActorEntity”, “SourceActorRole”, “SourceActorAttribute”, “TargetActorFull”, “TargetActorEntity”, “TargetActorRole”, “TargetActorAttribute”, “EventCode”, “EventRootCode”, “QuadClass”, “GoldsteinScore”, “Issues”, “ActionLat”, “ActionLong”, “LocationName”, “GeoCountryName”, “GeoStateName”, “SentenceID”, “URLs”, “NewsSources.” While there are columns included for geolocation of events, this feature is not fully implemented due to the difficult nature of accurately geolocating event data.\nThe *ActorFull columns include the full actor coding, which is made up of several three-letter CAMEO codes strung together. *ActorEntity breaks out the top-level code, which is usually a country code but can also be “IMG” for international militarized group, “IGO” for inter(national) governmental organizations, or “MNC” for multinational corporations. *ActorRole includes codes like “GOV”, “MED”, “EDU”, “MIL”, and *ActorAttribute includes modifiers, such as “MOS”, “INS”, “ELI” (Muslim, insurgent, and elite).\nEventCode is the full CAMEO code, while EventRootCode is the 20 top-level CAMEO categories. The QuadClass is an updated version of the quad class divisions seen in other event datasets. The changes include the creation of a 0 code for CAMEO category 01 (“Make a Statement”), rather than counting 01 as verbal cooperation, as well as several lower-level codes changing quad classes. Previous quadclass implementations sliced the CAMEO categories in a linear fashion. This new implementation takes into consideration what the CAMEO categories actually suggest in terms of material or verbal conflict/cooperation. In this scheme, 0 is “Neutral,” 1 is “Verbal Cooperation,” 2 is “Material Cooperation,” 3 is “Verbal Conflict,” and 4 is “Material Conflict.” The categories are as follows:\n\nThe GoldsteinScore variable is the same, standard scale used in previous datasets BIBREF17 . The final column relating to event actions is codes for Issues. These issues are based on simple keyword lookups and serve as a mechanism to add further context to a CAMEO code.

They are often provided with a small ground glass or white glaze area near the top for labelling with a pencil.Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents.

        "question": "What are the main considerations for chick care when raising backyard chickens?",
        "evidence": "Purchasing chickens - Chicken owners need to find a place to purchase chickens. Oftentimes, people purchase chickens at local feed stores, or through a hatchery.\n\nCreating a brooder - Chickens not being raised by a mother hen need assistance from their owner to survive. Chickens are raised in a brooder, which can look like a variety of things. Many individuals create their own brooder out of cardboard, plastic or wood. Different sources identify a variety of different square feet per bird needed, but a rule of thumb can be two square feet per chicken. This number can be lowered when the chick is young, but as they grow they will need at least two square feet per bird. It is important that chicken owners place their brooder in a draft-free place, yet still allow holes in the brooder for ventilation.[citation needed]\n\nHeating and bedding - Chicks require a warm environment. In a brooder, this warm environment is created artificially with a heat lamp. My Pet Chicken recommends a red heat lamp, because a white heat lamp can create a harsh and uncomfortable environment for the baby chicks. During the first week of the chicks' life, a temperature of 95 degrees Fahrenheit is required. The temperature can be decreased by 5 degrees F. each week of the chicks life, until they reach week 6. At week 6, the birds should have enough feathers grown to be moved into their chicken coop. Checking on chicks often is important, as chicks that are too cold will huddle together to attempt to retain warmth, and chicks that are too hot will spread out in the brooder in attempts to cool down. Temperature can be adjusted accordingly by lowering and raising the heat lamp in the chick's brooder. Temperature can also be monitored by the use of a thermometer.[citation needed] Wooden chips are often used in the bottom of the brooder as a bedding.\n\nFood and water - Chicks require different food than adult chickens. Chicks need a mash or dust food so that they are able to digest it without grit. Adult chickens are able to digest grit, which allows them to eat bigger food pellets. Purchasing chick food from a local feed store that is specifically for baby chicks will ensure that all nutritional requirements are being met. There are different types of food for different types of chicks. Chicks that are grown for egg-laying purposes require a lower protein level than chicks that are grown as a source of meat. Chicks should be fed and given water out of containers that ensure the chicks' safety, as some containers can injure the chicks or cause easy drowning.",
        "answer": "When raising backyard chickens, there are several considerations for chick care.  First of all, you have to purchase the chicks.  Then, you have to create a brooder to keep the chicks in.  Next, you have to address heating and bedding.  Finally, you have to provide them with the appropriate food and water.",

        "question": "What dataset do they propose?",
        "answer": "AntiScam dataset.",
        "evidence": "Considerable progress has been made building end-to-end dialog systems for collaborative tasks in which users cooperate with the system to achieve a common goal. Examples of collaborative tasks include making restaurant reservations and retrieving bus time-table information. Since users typically have clear and explicit intentions in collaborative tasks, existing systems commonly classify user utterances into pre-defined intents. In contrast, non-collaborative tasks are those where the users and the system do not strive to achieve the same goal. Examples of such tasks include deceiving attackers, persuading users to donate to a cause BIBREF1, and negotiating a product price BIBREF2, BIBREF3. In these tasks, users often perform complex actions that are beyond a simple set of pre-defined intents. In order to reach a common state, the user and the system need to build rapport and trust which naturally involves off-task content. Previous work did not model off-task content BIBREF2, which may have led to less optimal results. For example, in the persuasion task BIBREF1, users would ask the system “How do you feel about war?\" An example of an on-task system response that the system could have made is “Do you want to make a donation?\", which sticks to the task but neglects users' question. However, a better response to such an off-task question is “War is destructive and pitiless, but you can donate to help child victims of war.\" This response is better, as it has been found that users are more likely to end the conversation if the system neglects their questions BIBREF4. Therefore, we need to design a system that handles both on-task and off-task information appropriately and in a way that leads back to the system's goal.\nTo tackle the issue of incoherent system responses to off-task content, previous studies have built hybrid systems to interleave off-task and on-task content. BIBREF4 used a rule-based dialog manager for on-task content and a neural model for off-task content, and trained a reinforcement learning model to select between these two models based on the dialog context. However, such a method is difficult to train and struggles to generalize beyond the movie promotion task they considered. To tackle these problems, we propose a hierarchical intent annotation scheme that separates on-task and off-task information in order to provide detailed supervision. For on-task information, we directly use task-related intents for representation. Off-task information, on the other hand, is too general to categorize into specific intents, so we choose dialog acts that convey syntax information. These acts, such as “open question\" are general to all tasks.\nPrevious studies use template-based methods to maintain sentence coherence. However, rigid templates lead to limited diversity, causing the user losing engagement. On the other hand, language generation models can generate diverse responses but are bad at being coherent. We propose Multiple Intents and Semantic Slots Annotation Neural Network (MISSA) to combine the advantages of both template and generation models and takes advantage from the hierarchical annotation at the same time. MISSA follows the TransferTransfo framework BIBREF0 with three modifications: (i) We first concurrently predict user's, system's intents and semantic slots; (ii) We then perform conditional generation to improve generated response's coherence. Specifically, we generate responses conditioned on the above intermediate representation (intents and slots); (iii) Finally, we generate multiple responses with the nucleus sampling strategy BIBREF5 and then apply a response filter, which contains a set of pre-defined constraints to select coherent responses. The constraints in the filter can be defined according to specific task requirements or general conversational rules.\nTo enrich publicly available non-collaborative task datasets, we collect a new dataset AntiScam, where users defend themselves against attackers trying to collect personal information. As non-collaborative tasks are still relatively new to the study of dialog systems, there are insufficiently many meaningful datasets for evaluation and we hope this provides a valuable example. We evaluate MISSA on the newly collected AntiScam dataset and an existing PersuasionForGood dataset. Both automatic and human evaluations suggest that MISSA outperforms multiple competitive baselines.\nIn summary, our contributions include: (i) We design a hierarchical intent annotation scheme and a semantic slot annotation scheme to annotate the non-collaborative dialog dataset, we also propose a carefully-designed AntiScam dataset to facilitate the research of non-collaborative dialog systems. (ii) We propose a model that can be applied to all non-collaborative tasks, outperforming other baselines on two different non-collaborative tasks. (iii) We develop an anti-scam dialog system to occupy attacker's attention and elicit their private information for social good. Furthermore, we also build a persuasion dialog system to persuade people to donate to charities. We release the code and data.\n(i) We design a hierarchical intent annotation scheme and a semantic slot annotation scheme to annotate the non-collaborative dialog dataset, we also propose a carefully-designed AntiScam dataset to facilitate the research of non-collaborative dialog systems.",

        "evidence": "The task of generating natural language descriptions of structured data (such as tables) BIBREF2 , BIBREF3 , BIBREF4 has seen a growth in interest with the rise of sequence to sequence models that provide an easy way of encoding tables and generating text from them BIBREF0 , BIBREF1 , BIBREF5 , BIBREF6 .\nFor text generation tasks, the only gold standard metric is to show the output to humans for judging its quality, but this is too expensive to apply repeatedly anytime small modifications are made to a system. Hence, automatic metrics that compare the generated text to one or more reference texts are routinely used to compare models BIBREF7 . For table-to-text generation, automatic evaluation has largely relied on BLEU BIBREF8 and ROUGE BIBREF9 . The underlying assumption behind these metrics is that the reference text is gold-standard, i.e., it is the ideal target text that a system should generate. In practice, however, when datasets are collected automatically and heuristically, the reference texts are often not ideal. Figure FIGREF2 shows an example from the WikiBio dataset BIBREF0 . Here the reference contains extra information which no system can be expected to produce given only the associated table. We call such reference texts divergent from the table.\nWe show that existing automatic metrics, including BLEU, correlate poorly with human judgments when the evaluation sets contain divergent references (§ SECREF36 ). For many table-to-text generation tasks, the tables themselves are in a pseudo-natural language format (e.g., WikiBio, WebNLG BIBREF6 , and E2E-NLG BIBREF10 ). In such cases we propose to compare the generated text to the underlying table as well to improve evaluation. We develop a new metric, PARENT (Precision And Recall of Entailed N-grams from the Table) (§ SECREF3 ). When computing precision, PARENT effectively uses a union of the reference and the table, to reward correct information missing from the reference. When computing recall, it uses an intersection of the reference and the table, to ignore extra incorrect information in the reference. The union and intersection are computed with the help of an entailment model to decide if a text n-gram is entailed by the table. We show that this method is more effective than using the table as an additional reference. Our main contributions are:\nWhen computing precision, PARENT effectively uses a union of the reference and the table, to reward correct information missing from the reference.",

We used temporal and linguistic patterns of users to do the matching.\nWe experimented with linguistic, temporal, and combined temporal-linguistic models using standard and novel techniques. The methods based on our novel confusion model outperformed the more standard ones in all cases. We showed that both temporal and linguistic information are useful for matching users, with the best temporal model performing with an accuracy of $.10$ and the best linguistic model performing with an accuracy of $0.27$ . Even though the linguistic models vastly outperformed the temporal models, when combined the temporal-linguistic models outperformed both with an accuracy of $0.31$ . The improvement in the performance of the combined models suggests that although temporal information is dwarfed by linguistic information, in terms of its contribution to digital stylometry, it nonetheless provides non-overlapping information with the linguistic data.\nOur models were evaluated on $5,612$ users with a total of $11,224$ accounts on Twitter and Facebook combined. In contrast to other works in this area, we did not use any profile information in our matching models. The only information that was used in our models were the time and the linguistic content of posts by the users. This is in accordance with traditional stylometry techniques (since people could lie or misstate this information). Also, we wanted to show that there are implicit clues about the identity of users in the content (language) and context (time) of the users' interactions with social networks that can be used to link their accounts across different services.\nIn addition to the technical contributions (such as our confusion model), we hope that this paper is able to shed light on the relative ease with which seemingly innocuous information can be used to track users across social networks, even when signing up on different services using completely different account and profile information.

The technique is most commonly used with photovoltaic (PV) solar systems, but can also be used with wind turbines, optical power transmission and thermophotovoltaics.\n\nPV solar systems have varying relationships to inverter systems, external grids, battery banks, and other electrical loads. The central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on the amount of available sunlight, shading, solar panel temperature and the load's electrical characteristics. As these conditions vary, the load characteristic (impedance) that gives the highest power transfer changes. The system is optimized when the load characteristic changes to keep power transfer at highest efficiency. This optimal load characteristic is called the maximum power point (MPP). MPPT is the process of adjusting the load characteristic as the conditions change. Circuits can be designed to present optimal loads to the photovoltaic cells and then convert the voltage, current, or frequency to suit other devices or systems.\n\nSolar cells' non-linear relationship between temperature and total resistance can be analyzed based on the Current-voltage (I-V) curve and the power-voltage (P-V) curves. MPPT samples cell output and applies the proper resistance (load) to obtain maximum power. MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors. Solar inverters convert DC power to AC power and may incorporate MPPT.\n\nThe power at the MPP (Pmpp) is the product of the MPP voltage (Vmpp) and MPP current (Impp).\n\nIn general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the curve.",

        "question": "What is the Aspect-Based Sentiment Analysis (ABSA)?",
        "answer": "Aspect-Based Sentiment Analysis (ABSA) is a branch of sentiment analysis which deals with extracting the opinion targets (aspects) as well as the sentiment expressed towards them.",
        "evidence": "Understanding what people are talking about and how they feel about it is valuable especially for industries which need to know the customers' opinions on their products. Aspect-Based Sentiment Analysis (ABSA) is a branch of sentiment analysis which deals with extracting the opinion targets (aspects) as well as the sentiment expressed towards them. For instance, in the sentence The spaghetti was out of this world., a positive sentiment is mentioned towards the target which is spaghetti. Performing these tasks requires a deep understanding of the language. Traditional machine learning methods such as SVM BIBREF2, Naive Bayes BIBREF3, Decision Trees BIBREF4, Maximum Entropy BIBREF5 have long been practiced to acquire such knowledge. However, in recent years due to the abundance of available data and computational power, deep learning methods such as CNNs BIBREF6, BIBREF7, BIBREF8, RNNs BIBREF9, BIBREF10, BIBREF11, and the Transformer BIBREF12 have outperformed the traditional machine learning techniques in various tasks of sentiment analysis. Bidirectional Encoder Representations from Transformers (BERT) BIBREF13 is a deep and powerful language model which uses the encoder of the Transformer in a self-supervised manner to learn the language model. It has been shown to result in state-of-the-art performances on the GLUE benchmark BIBREF14 including text classification. BIBREF1 show that adding domain-specific information to this model can enhance its performance in ABSA. Using their post-trained BERT (BERT-PT), we add adversarial examples to further improve BERT's performance on Aspect Extraction (AE) and Aspect Sentiment Classification (ASC) which are two major tasks in ABSA. A brief overview of these two sub-tasks is given in Section SECREF3.\nAdversarial examples are a way of fooling a neural network to behave incorrectly BIBREF15. They are created by applying small perturbations to the original inputs. In the case of images, the perturbations can be invisible to human eye, but can cause neural networks to output a completely different response from the true one. Since neural nets make mistakes on these examples, introducing them to the network during the training can improve their performance. This is called adversarial training which acts as a regularizer to help the network generalize better BIBREF0. Due to the discrete nature of text, it is not feasible to produce perturbed examples from the original inputs. As a workaround, BIBREF16 apply this technique to the word embedding space for text classification. Inspired by them and building on the work of BIBREF1, we experiment with adversarial training for ABSA.\nOur contributions are twofold. First, by carrying out an ablation study on the number of training epochs and the values for dropout in the classification layer, we show that there are values that outperform the specified ones for BERT-PT. Second, we introduce the application of adversarial training in ABSA by proposing a novel architecture which combines adversarial training with the BERT language model for AE and ASC tasks. Our experiments show that the proposed model outperforms the best performance of BERT-PT in both tasks.\nAspect-Based Sentiment Analysis (ABSA) is a branch of sentiment analysis which deals with extracting the opinion targets (aspects) as well as the sentiment expressed towards them.",

Aloy becomes curious about her origins and is told by Rost that if she wins the Proving, a competition to earn the right to become a member of the Nora, the tribe's Matriarchs might concede this information. Aloy spends some years training in combat and survival under Rost's instruction. After coming of age, Aloy participates in the Proving; she wins the competition, but masked cultists attack the Nora. Rost sacrifices himself to save Aloy from their leader, Helis (Crispin Freeman). When Aloy awakens, the Matriarchs explain that Aloy was found as an infant before a sealed door within the Nora's sacred mountain and that these suspicious origins were the reason for her being an outcast. The Matriarchs name Aloy a \"Seeker,\" allowing her to leave their lands in pursuit of the cultists. Aloy eventually learns that the cultists are part of a splinter Carja faction called the Eclipse and that Aloy was targeted due to her resemblance to an Old World scientist named Elisabet Sobeck (also voiced by Burch). Aloy locates the ruined corporate campus of Faro Automated Solutions and discovers that the Old World was destroyed nearly a thousand years ago after Faro lost control of its automated peacekeeper military robots.

        "evidence": "For an ever increasing spectrum of applications (e.g., medical text analysis, opinion mining, sentiment analysis, social media text analysis, customer intelligence, fraud analytics etc.) mining and analysis of unstructured natural language text data is necessary BIBREF0, BIBREF1, BIBREF2.\nOne of key challenge while designing such text analytics (TA) applications is to identify right set of features. For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nWe next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available.",

        "evidence": "Online social networks have become one of the most disruptive communication platforms, as everyday billions of individuals use them to interact with each other. Their penetration in our everyday lives seems ever-growing and has in turn generated a massive volume of publicly available data open to analysis. The digital footprints left across these multiple media platforms provide us with a unique source to study and understand how the linguistic phenotype of a given user is related to social attributes such as socioeconomic status (SES).\nThe quantification and inference of SES of individuals is a long lasting question in the social sciences. It is a rather difficult problem as it may depend on a combination of individual characteristics and environmental variables BIBREF0 . Some of these features can be easier to assess like income, gender, or age whereas others, relying to some degree on self-definition and sometimes entangled with privacy issues, are harder to assign like ethnicity, occupation, education level or home location. Furthermore, individual SES correlates with other individual or network attributes, as users tend to build social links with others of similar SES, a phenomenon known as status homophily BIBREF1 , arguably driving the observed stratification of society BIBREF2 . At the same time, shared social environment, similar education level, and social influence have been shown to jointly lead socioeconomic groups to exhibit stereotypical behavioral patterns, such as shared political opinion BIBREF3 or similar linguistic patterns BIBREF4 . Although these features are entangled and causal relation between them is far from understood, they appear as correlations in the data.\nDatasets recording multiple characteristics of human behaviour are more and more available due to recent developments in data collection technologies and increasingly popular online platforms and personal digital devices. The automatic tracking of online activities, commonly associated with profile data and meta-information; the precise recording of daily activities, interaction dynamics and mobility patterns collected through mobile personal devices; together with the detailed and expert annotated census data all provide new grounds for the inference of individual features or behavioral patterns BIBREF5 . The exploitation of these data sources has already been proven to be fruitful as cutting edge recommendation systems, advanced methods for health record analysis, or successful prediction tools for social behaviour heavily rely on them BIBREF6 . Nevertheless, despite the available data, some inference tasks, like individual SES prediction, remain an open challenge.\nThe precise inference of SES would contribute to overcome several scientific challenges and could potentially have several commercial applications BIBREF7 . Further, robust SES inference would provide unique opportunities to gain deeper insights on socioeconomic inequalities BIBREF8 , social stratification BIBREF2 , and on the driving mechanisms of network evolution, such as status homophily or social segregation.\nIn this work, we take a horizontal approach to this problem and explore various ways to infer the SES of a large sample of social media users. We propose different data collection and combination strategies using open, crawlable, or expert annotated socioeconomic data for the prediction task. Specifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations. Individual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations. Each of these datasets is then used as ground-truth to infer the SES of Twitter users from profile and semantic features similar to BIBREF9 . We aim to explore and assess how the SES of social media users can be obtained and how much the inference problem depends on annotation and the user's individual and linguistic attributes.\nWe provide in Section SECREF2 an overview of the related literature to contextualize the novelty of our work. In Section SECREF3 we provide a detailed description of the data collection and combination methods. In Section SECREF4 we introduce the features extracted to solve the SES inference problem, with results summarized in Section SECREF5 . Finally, in Section SECREF6 and SECREF7 we conclude our paper with a brief discussion of the limitations and perspectives of our methods.\nWe propose different data collection and combination strategies using open, crawlable, or expert annotated socioeconomic data for the prediction task.",

In Australia and Ireland there was a government funded \"free milk for school children\" program, and milk was distributed at morning recess in 1/3 pint bottles. With the conversion to metric measures, the milk industry was concerned that the replacement of the pint bottles with 500 mL bottles would result in a 13.6% drop in milk consumption; hence, all pint bottles were recalled and replaced by 600 mL bottles. With time, due to the steadily increasing cost of collecting, transporting, storing and cleaning glass bottles, they were replaced by cardboard cartons. A number of designs were used, including a tetrahedron which could be close-packed without waste space, and could not be knocked over accidentally (slogan: \"No more crying over spilt milk\"). However, the industry eventually settled on a design similar to that used in the United States.

This allows it to exhibit temporal dynamic behavior. Derived from feedforward neural networks, RNNs can use their internal state (memory) to process variable length sequences of inputs. This makes them applicable to tasks such as unsegmented, connected handwriting recognition or speech recognition. Recurrent neural networks are theoretically Turing complete and can run arbitrary programs to process arbitrary sequences of inputs.\n\nThe term \"recurrent neural network\" is used to refer to the class of networks with an infinite impulse response, whereas \"convolutional neural network\" refers to the class of finite impulse response. Both classes of networks exhibit temporal dynamic behavior. A finite impulse recurrent network is a directed acyclic graph that can be unrolled and replaced with a strictly feedforward neural network, while an infinite impulse recurrent network is a directed cyclic graph that can not be unrolled.\n\nBoth finite impulse and infinite impulse recurrent networks can have additional stored states, and the storage can be under direct control by the neural network. The storage can also be replaced by another network or graph if that incorporates time delays or has feedback loops.

        "question": "Why computer scientists may feel uncomfortable about  social and cultural concepts in analysis?",
        "answer": "Because there is no absolute ground truth for social and cultural concepts, and definitions might be contested over time. However, for computer scientists, their primary measure of success is often based on comparing a model’s output against “ground truth” or a “gold standard”.",
        "evidence": "A core step in many analyses is translating social and cultural concepts (such as hate speech, rumor, or conversion) into measurable quantities. Before we can develop measurements for these concepts (the operationalization step, or the “implementation” step as denoted by BIBREF12 ), we need to define them. In the conceptualization phase we often start with questions such as: who are the domain experts, and how have they approached the topic? We are looking for a definition of the concept that is flexible enough to apply on our dataset, yet formal enough for computational research. For example, our introductory study on hate speech BIBREF0 used a statement on hate speech produced by the European Union Court of Human Rights. The goal was not to implement this definition directly in software but to use it as a reference point to anchor subsequent analyses.\nIf we want to move beyond the use of ad hoc definitions, it can be useful to distinguish between what political scientists Adcock and Collier call the “background concept” and the “systematized concept” BIBREF13 . The background concept comprises the full and diverse set of meanings that might be associated with a particular term. This involves delving into theoretical, conceptual, and empirical studies to assess how a concept has been defined by other scholars and, most importantly, to determine which definition is most appropriate for the particular research question and the theoretical framework in which it is situated. That definition, in turn, represents the systematized concept: the formulation that is adopted for the study.\nIt is important to consider that for social and cultural concepts there is no absolute ground truth. There are often multiple valid definitions for a concept (the “background” concept in the terms of Adcock and Collier), and definitions might be contested over time. This may be uncomfortable for computer scientists, whose primary measure of success is often based on comparing a model's output against “ground truth” or a “gold standard”, e.g., by comparing a sentiment classifier's output against manual annotations. However, the notion of ground truth is uncommon in the humanities and the social sciences and it is often taken too far in machine learning. BIBREF14 notes that in literary criticism and the digital humanities more broadly “interpretation, ambiguity, and argumentation are prized far above ground truth and definitive conclusions\". BIBREF15 draw attention to the different attitudes of literary scholars and computational linguists towards ambiguity, stating that “In Computational Linguistics [..] ambiguity is almost uniformly treated as a problem to be solved; the focus is on disambiguation, with the assumption that one true, correct interpretation exists.\" The latter is probably true for tasks such as spam filtering, but in the social sciences and the humanities many relevant concepts are fundamentally unobservable, such as latent traits of political actors BIBREF16 or cultural fit in organizations BIBREF17 , leading to validation challenges. Moreover, when the ground truth comes from people, it may be influenced by ideological priors, priming, simple differences of opinion or perspective, and many other factors BIBREF18 . We return to this issue in our discussions on validation and analysis.\nIt is important to consider that for social and cultural concepts there is no absolute ground truth.

In all these methods, an embedding is generated for a tweet and is used as its feature representation with a classifier.\nBaseline Methods: As baselines, we experiment with three broad representations. (1) Char n-grams: It is the state-of-the-art method BIBREF0 which uses character n-grams for hate speech detection. (2) TF-IDF: TF-IDF are typical features used for text classification. (3) BoWV: Bag of Words Vector approach uses the average of the word (GloVe) embeddings to represent a sentence. We experiment with multiple classifiers for both the TF-IDF and the BoWV approaches.\nProposed Methods: We investigate three neural network architectures for the task, described as follows. For each of the three methods, we initialize the word embeddings with either random embeddings or GloVe embeddings. (1) CNN: Inspired by Kim et. al BIBREF3 's work on using CNNs for sentiment classification, we leverage CNNs for hate speech detection. We use the same settings for the CNN as described in BIBREF3 . (2) LSTM: Unlike feed-forward neural networks, recurrent neural networks like LSTMs can use their internal memory to process arbitrary sequences of inputs. Hence, we use LSTMs to capture long range dependencies in tweets, which may play a role in hate speech detection. (3) FastText: FastText BIBREF4 represents a document by average of word vectors similar to the BoWV model, but allows update of word vectors through Back-propagation during training as opposed to the static word representation in the BoWV model, allowing the model to fine-tune the word representations according to the task.\nAll of these networks are trained (fine-tuned) using labeled data with back-propagation. Once the network is learned, a new tweet is tested against the network which classifies it as racist, sexist or neither. Besides learning the network weights, these methods also learn task-specific word embeddings tuned towards the hate speech labels. Therefore, for each of the networks, we also experiment by using these embeddings as features and various other classifiers like SVMs and GBDTs as the learning method.\nUnlike feed-forward neural networks, recurrent neural networks like LSTMs can use their internal memory to process arbitrary sequences of inputs.

        "answer": "Running is a great exercise, but not all running surfaces are created equal. Traditionally, those who run \"runners\" will run 5-7 days a week. Runners will average between 3 miles per run up to 20 miles per run. While running is great exercise and very efficient at burning calories, it can be hard on the body. Specifically the leg joints. The average runner will strike the surface they are running on 1,480 times per mile. So if you are running 10 miles, thats just under 15,000 foot strikes. This repetitive striking can deteriorate the body joints over time. Therefore, the type of surface a runner runs on, can have a huge impact on the body. Some surfaces are harder than others, the harder the surface, the harder on the body, legs and joints. Concrete is harder than asphalt, asphalt is harder than a dirt trail and a dirt trail is harder than a high school track surface. Example, concrete can be 30% harder surface than asphalt. Running is a great exercise and millions of people enjoy running. But if you want to run long, as in for a long time, choose your running surface for the long run.

It is an example of cannibalization.\nThe term alludes to the Osborne Computer Corporation, whose second product did not become available until more than a year after it was announced. The company's subsequent bankruptcy was widely blamed on reduced sales after the announcement.\nThe Osborne Effect states that prematurely discussing future, unavailable products damages sales of existing products. The name comes from the planned replacement of the Osborne 1, an early personal computer first sold by the Osborne Computer Corporation in 1981. In 1983, founder Adam Osborne pre-announced several next-generation computer models (the Osborne Executive and Osborne Vixen), which were only prototypes, highlighting the fact that they would outperform the existing model as the prototypes dramatically cut down assembly time. A widely held belief was that sales of the Osborne 1 fell sharply as customers anticipated those more advanced systems, leading to a sales decline from which Osborne Computer was unable to recover. This belief appeared in the media almost immediately after the company's September 1983 bankruptcy:\n\nTo give the jazzy $2,495 Osborne Executive a running start, Adam began orchestrating publicity early in 1983. We, along with many other magazines, were shown the machine in locked hotel rooms. We were required not to have anything in print about it until the planned release date in mid-April. As far as we know, nothing did appear in print, but dealers heard about the plans and cancelled orders for the Osborne 1 in droves. In early April, Osborne told dealers he would be showing them the machine on a one-week tour the week of 17 April, and emphasized that the new machine was not a competitor for the Osborne 1. But dealers didn't react the way Osborne expected; said Osborne, \"All of them just cancelled their orders for the Osborne 1.\"\n\nOsborne reacted by drastically cutting prices on the Osborne 1 in an effort to stimulate cash flow. But nothing seemed to work, and for several months sales were practically non-existent.\n\nPre-announcement is done for several reasons: to reassure current customers that there is improvement or lower cost coming, to increase the interest of the media and investors in the company's future prospects, and to intimidate or confuse competitors. When done correctly, the sales or cash flow impact to the company is minimal, with the revenue drop for the current product being offset by orders or completed sales of the new product as it becomes available. However, when the Osborne effect occurs, the quantity of unsold goods increases and the company must react by discounting and/or lowering production of the current product, both of which depress cash flow.",

        "evidence": "The evolution of baseball from older bat-and-ball games is difficult to trace with precision. Consensus once held that today's baseball is a North American development from the older game rounders, popular among children in Great Britain and Ireland. American baseball historian David Block suggests that the game originated in England; recently uncovered historical evidence supports this position. Block argues that rounders and early baseball were actually regional variants of each other, and that the game's most direct antecedents are the English games of stoolball and \"tut-ball\". The earliest known reference to baseball is in a 1744 British publication, A Little Pretty Pocket-Book, by John Newbery. Block discovered that the first recorded game of \"Bass-Ball\" took place in 1749 in Surrey, and featured the Prince of Wales as a player. This early form of the game was apparently brought to Canada by English immigrants.\n\nBy the early 1830s, there were reports of a variety of uncodified bat-and-ball games recognizable as early forms of baseball being played around North America. The first officially recorded baseball game in North America was played in Beachville, Ontario, Canada, on June 4, 1838. In 1845, Alexander Cartwright, a member of New York City's Knickerbocker Club, led the codification of the so-called Knickerbocker Rules, which in turn were based on rules developed in 1837 by William R. Wheaton of the Gotham Club. While there are reports that the New York Knickerbockers played games in 1845, the contest long recognized as the first officially recorded baseball game in U.S. history took place on June 19, 1846, in Hoboken, New Jersey: the \"New York Nine\" defeated the Knickerbockers, 23–1, in four innings. With the Knickerbocker code as the basis, the rules of modern baseball continued to evolve over the next half-century. By the time of the Civil War, baseball had begun to overtake its fellow bat-and-ball sport cricket in popularity within the United States, due in part to baseball being of a much shorter duration than the form of cricket played at the time, as well as the fact that troops during the Civil War did not need a specialized playing surface to play baseball, as they would have required for cricket.",
        "answer": "Although the history of baseball cannot be determined with great precision, it is said that the game originated in England during the 1700s. The first official game to be played in North America took place in 1838 in Beachville, Ontario, Canada and in 1846 the first official game took place in the United States. The original rules of baseball, called the Knickerbocker Rules\" were established in 1845 and formed the basis of the rules of modern baseball that evolved over the following century.",

Unlike the traditional CTS task, our QA-CTS task aims to discover the most related text from original paragraph text. For some cases, it is already the final answer in deed (e.g., extracting sub-string). While for other cases, it needs several steps to obtain the final answer, such as entity names conversion and negative words recognition. Our presented QA-CTS task unifies the output format of the traditional CTS task and make the training data shareable, thus enriching the training data. The main contributions of this work can be summarized as follows.\nOur dataset is annotated based on Chinese pathology reports provided by the Department of Gastrointestinal Surgery, Ruijin Hospital. It contains 17,833 sentences, 826,987 characters and 2,714 question-answer pairs. All question-answer pairs are annotated and reviewed by four clinicians with three types of questions, namely tumor size, proximal resection margin and distal resection margin. These annotated instances have been partitioned into 1,899 training instances (12,412 sentences) and 815 test instances (5,421 sentences). Each instance has one or several sentences. Detailed statistics of different types of entities are listed in Table TABREF20.\nIn this paper, we present a question answering based clinical text structuring (QA-CTS) task, which unifies different clinical text structuring tasks and utilize different datasets. A novel model is also proposed to integrate named entity information into a pre-trained language model and adapt it to QA-CTS task. Initially, sequential results of named entity recognition on both paragraph and query texts are integrated together. Contextualized representation on both paragraph and query texts are transformed by a pre-trained language model. Then, the integrated named entity information and contextualized representation are integrated together and fed into a feed forward network for final prediction. Experimental results on real-world dataset demonstrate that our proposed model competes favorably with strong baseline models in all three specific tasks. The shared task and shared model introduced by QA-CTS task has also been proved to be useful for improving the performance on most of the task-specific datasets. In conclusion, the best way to achieve the best performance for a specific dataset is to pre-train the model in multiple datasets and then fine tune it on the specific dataset.\nOur presented QA-CTS task unifies the output format of the traditional CTS task and make the training data shareable, thus enriching the training data.\nAll question-answer pairs are annotated and reviewed by four clinicians with three types of questions, namely tumor size, proximal resection margin and distal resection margin. \nExperimental results on real-world dataset demonstrate that our proposed model competes favorably with strong baseline models in all three specific tasks.",

The organisation reports a worldwide membership of over 1.7 million, comprising soldiers, officers and adherents collectively known as Salvationists. Its founders sought to bring salvation to the poor, destitute, and hungry by meeting both their \"physical and spiritual needs\". It is present in 133 countries, running charity shops, operating shelters for the homeless and disaster relief, and humanitarian aid to developing countries.\n\nThe theology of the Salvation Army is derived from Methodism, although it is distinctive in institution and practice. A distinctive characteristic of the Salvation Army is its use of titles derived from military ranks, such as \"lieutenant\" or \"major\". It does not celebrate the rites of Baptism and Holy Communion. However, the Army's doctrine is aligned with the Wesleyan–Arminian tradition, particularly the holiness movement. The Army's purposes are \"the advancement of the Christian religion... of education, the relief of poverty, and other charitable objects beneficial to society or the community of mankind as a whole\".\n\nThe Army was founded in 1865 in London by one-time Methodist preacher William Booth and his wife Catherine as the East London Christian Mission, and can trace its origins to the Blind Beggar tavern. In 1878, Booth reorganised the mission, becoming its first General and introducing the military structure which has been retained as a matter of tradition. Its highest priority is its Christian principles. The current international leader of The Salvation Army and chief executive officer (CEO) is General Brian Peddle, who was elected by the High Council of The Salvation Army on 3 August 2018.\n\nIn 2011, Charity Watch rated the Salvation Army an \"A−\" to an \"A\", indicating a high level of financial efficiency and organisational transparency. The Salvation Army has received an A-rating from the American Institute of Philanthropy.\n\nThe Salvation Army is one of the world's largest providers of social aid,[citation needed] with expenditures including operating costs of $2.6 billion in 2004, helping more than 32 million people in the U.S. alone. In addition to community centres and disaster relief, the organisation does work in refugee camps, especially among displaced people in Africa. In the United Kingdom, the Salvation Army is no longer the largest nongovernmental provider of social services; however, it still provides a significant service to people in need.

        "answer": "Sarcasm detection may depend on sentiment and other cognitive aspects.",
        "evidence": "Sarcasm detection is an important subtask of sentiment analysis BIBREF27 . Since sarcastic sentences are subjective, they carry sentiment and emotion-bearing information. Most of the studies in the literature BIBREF28 , BIBREF29 , BIBREF9 , BIBREF30 include sentiment features in sarcasm detection with the use of a state-of-the-art sentiment lexicon. Below, we explain how sentiment information is key to express sarcastic opinions and the approach we undertake to exploit such information for sarcasm detection.\nIn general, most sarcastic sentences contradict the fact. In the sentence “I love the pain present in the breakups\" (Figure FIGREF4 ), for example, the word “love\" contradicts “pain present in the breakups”, because in general no-one loves to be in pain. In this case, the fact (i.e., “pain in the breakups\") and the contradictory statement to that fact (i.e., “I love\") express sentiment explicitly. Sentiment shifts from positive to negative but, according to sentic patterns BIBREF31 , the literal sentiment remains positive. Sentic patterns, in fact, aim to detect the polarity expressed by the speaker; thus, whenever the construction “I love” is encountered, the sentence is positive no matter what comes after it (e.g., “I love the movie that you hate”). In this case, however, the sentence carries sarcasm and, hence, reflects the negative sentiment of the speaker.\nIn another example (Figure FIGREF4 ), the fact, i.e., “I left the theater during the interval\", has implicit negative sentiment. The statement “I love the movie\" contradicts the fact “I left the theater during the interval\"; thus, the sentence is sarcastic. Also in this case the sentiment shifts from positive to negative and hints at the sarcastic nature of the opinion.\nThe above discussion has made clear that sentiment (and, in particular, sentiment shifts) can largely help to detect sarcasm. In order to include sentiment shifting into the proposed framework, we train a sentiment model for sentiment-specific feature extraction. Training with a CNN helps to combine the local features in the lower layers into global features in the higher layers. We do not make use of sentic patterns BIBREF31 in this paper but we do plan to explore that research direction as a part of our future work. In the literature, it is found that sarcasm is user-specific too, i.e., some users have a particular tendency to post more sarcastic tweets than others. This acts as a primary intuition for us to extract personality-based features for sarcasm detection.\nAs discussed in the literature (Riloff et al., 2013), sarcasm detection may depend on sentiment and other cognitive aspects. For this reason, we incorporate both sentiment and emotion clues in our framework.",

        "answer": "By increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU), weight normalization and dropout.",
        "evidence": "Conventional automatic speech recognition (ASR) systems typically consist of several independently learned components: an acoustic model to predict context-dependent sub-phoneme states (senones) from audio, a graph structure to map senones to phonemes, and a pronunciation model to map phonemes to words. Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other. We show competitive results on Wall Street Journal (WSJ), and 2000hr Fisher+Switchboard (F+S). Using only greedy decoding without a language model we achieve 3.86% WER on LibriSpeech test-clean.\nThis paper makes the following contributions:\nLiptchinsky et al.

        "evidence": "The Semantic Web BIBREF0 , BIBREF1 and the growing popularity of Linked Data (data that are published using Semantic Web technologies) have renewed interest in concept-to-text natural language generation (nlg), especially text generation from ontologies BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 . An ontology provides a conceptualization of a knowledge domain (e.g., consumer electronics, diseases) by defining the classes and subclasses of the individuals (entities) in the domain, the possible relations between them etc. The current standard to specify Semantic Web ontologies is owl BIBREF11 , BIBREF12 , a formal language based on description logics BIBREF13 , rdf, and rdf schema BIBREF14 . Given an owl ontology for a knowledge domain, one can publish on the Web machine-readable statements about the domain (e.g., available products, known diseases, their features or symptoms), with the statements having formally defined semantics based on the ontology. nlg can then produce texts describing classes or individuals of the ontology (e.g., product descriptions, information about diseases) from the same statements. This way the same information becomes more easily accessible to both computers (which read the machine-readable statements) and end-users (who read the texts), which is one of the main goals of the Semantic Web.\nnlg systems typically employ a pipeline architecture BIBREF15 . Firstly, content selection chooses the logical facts (axioms, in the case of an owl ontology) to be expressed in the text to be generated. The purpose of the next stage, text planning, ranges from simply ordering the facts to be expressed, in effect also ordering the sentences that will express them, to making more complex decisions about the rhetorical structure of the text. Lexicalization then selects the words and syntactic structures to express each fact as a single sentence. Sentence aggregation may then combine shorter sentences into longer ones. Another component generates appropriate referring expressions (pronouns, noun phrases etc.), and surface realization produces the final text, based on internal representations of the previous decisions. Each stage of the pipeline in effect performs a local optimization, constrained by decisions of the previous stages, and largely unaware of the consequences of its own decisions on the subsequent stages.\nThe pipeline architecture has engineering advantages (e.g., it is easier to specify and monitor the input and output of each stage), but produces texts that may be suboptimal, since the decisions of the generation stages are actually co-dependent BIBREF16 , BIBREF17 , BIBREF18 . Content selection, for example, may greedily select the most important facts among those that are relevant to the purpose of the text, but these facts may require too many words to express, which may be undesirable when space is limited or expensive. Selecting other facts, possibly only slightly less important, may allow the lexicalization stage to use much fewer words, or to report more facts in the same space. Decisions made during content selection and lexicalization (facts to express, words and syntactic structures to use) may also lead to more or fewer sentence aggregation opportunities, affecting the length and readability of the texts. Some of these issues can be addressed by over-generating at each stage (e.g., producing several alternative sets of facts at the end of content selection, several alternative lexicalizations etc.) and employing a final ranking component to select the best combination BIBREF19 . This over-generate and rank approach, however, may also fail to find an optimal solution, and generates an exponentially large number of candidate solutions when several components are pipelined.\nIn this article, we present an Integer Linear Programming (ilp) model that, unlike pipeline architectures, jointly considers choices available in content selection, lexicalization, and sentence aggregation to avoid greedy local decisions and produce more compact texts, i.e., texts that report more facts per word. Compact texts are desirable, for example, when generating short product descriptions to be included as advertisements in Web search results BIBREF20 , BIBREF21 . Question answering may also involve generating a natural language summary of facts (e.g., rdf triples) related to a question, without exceeding a maximum text length BIBREF22 ; the more compact the summary, the more facts can be reported in the available space, increasing the chances of reporting the information sought by the user. Compact texts are also desirable when showing texts on devices with small screens BIBREF23 or as subtitles BIBREF24 .\nIf an importance score is available for each fact, our model can take it into account to maximize the total importance (instead of the total number) of the expressed facts per word. The model itself, however, does not produce importance scores; we assume that the scores are produced by a separate process BIBREF25 , BIBREF26 , not included in our content selection. For simplicity, in the experiments of this article we treat all the facts as equally important. An extended version of our ilp model also considers a limited form of referring expression generation, where the best name must be chosen per individual or class among multiple alternatives. The extended model also avoids sentences that report information that is obvious (to humans) from the names of the individuals and classes (e.g., “A red wine is a kind of wine with red color”). Experiments with three owl ontologies from very different knowledge domains (wines, consumer electronics, diseases) confirm that our models lead to more compact texts, compared to pipeline systems with the same components, with no deterioration or with improvements in the perceived quality of the generated texts. Although solving ilp problems is in general np-hard BIBREF27 , off-the-shelf ilp solvers can be used. The available solvers guarantee finding a globally optimum solution, and they are very fast in practice in the ilp problems we consider, when the the number of available facts (per individual or class being described) is small. We also present an approximation of our ilp models, which is more efficient when the number of available facts is larger and longer texts need to be generated.\nOur ilp models (and approximations) have been embedded in Naturalowl BIBREF10 , an nlg system for owl, as alternatives to the system's original pipeline architecture. We base our work on Naturalowl, because it is the only open-source nlg system for owl that implements all the processing stages of a typical nlg system BIBREF15 , it is extensively documented, and has been tested with several ontologies. The processing stages and linguistic resources of Naturalowl are typical of nlg systems BIBREF28 . Hence, we believe that our work is, at least in principle, also applicable to other nlg systems. Our ilp models do not directly consider text planning, but rely on the (external to the ilp model) text planner of Naturalowl. We hope to include more text planning and referring expression generation decisions directly in our ilp model in future work. We also do not consider surface realization, since it is not particularly interesting in Naturalowl; all the decisions have in effect already been made by the time this stage is reached.\nThe remainder of this article is structured as follows. Section \"Background Information about NaturalOWL\" below provides background information about Naturalowl. Section \"Our Integer Linear Programming Models\" defines our ilp models. Section \"Computational Complexity and Approximations\" discusses the computational complexity of our ilp models, along with the more efficient approximation that can be used when then number of available facts is large.

The former comes from the scripts of the Friends TV sitcom. The other is made up of Facebook messenger chats. Each subset includes $1,000$ English dialogues, and each dialogue can be further divided into a few consecutive utterances. All the utterances are annotated by five annotators on a crowd-sourcing platform (Amazon Mechanical Turk), and the labeling work is only based on the textual content. Annotator votes for one of the seven emotions, namely Ekman’s six basic emotions BIBREF1, plus the neutral. If none of the emotion gets more than three votes, the utterance will be marked as “non-neutral”.\nFor the datasets, there are properties worth additional mentioning. Although Friends and EmotionPush share the same data format, they are quite different in nature. Friends is a speech-based dataset which is annotated dialogues from the TV sitcom. It means most of the utterances are generated by the a few main characters. The personality of a character often affects the way of speaking, and therefore “who is the speaker\" might provide extra clues for emotion prediction. In contrast, EmotionPush does not have this trait due to the anonymous mechanism. In addition, features such as typo, hyperlink, and emoji that only appear in chat-based data will need some domain-specific techniques to process.\nIncidentally, the objective of the challenge is to predict the emotion for each utterance. Just, according to EmotionX 2019 specification, there are only four emotions be selected as our label candidates, which are Joy, Sadness, Anger, and Neutral. These emotions will be considered during performance evaluation. The technical detail will also be introduced and discussed in following Section SECREF13 and Section SECREF26.\nEach subset includes $1,000$ English dialogues, and each dialogue can be further divided into a few consecutive utterances.",

        "answer": "Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American singer, songwriter, dancer, and philanthropist. Dubbed the \"King of Pop\", he is regarded as one of the most significant cultural figures of the 20th century. Over a four-decade career, his contributions to music, dance, and fashion, along with his publicized personal life, made him a global figure in popular culture. Jackson influenced artists across many music genres; through stage and video performances, he popularized complicated dance moves such as the moonwalk, to which he gave the name, as well as the robot.\nThe eighth child of the Jackson family, Jackson made his public debut in 1964 with his older brothers Jackie, Tito, Jermaine, and Marlon as a member of the Jackson 5 (later known as the Jacksons). Jackson began his solo career in 1971 while at Motown Records. He became a solo star with his 1979 album Off the Wall. His music videos, including those for \"Beat It\", \"Billie Jean\", and \"Thriller\" from his 1982 album Thriller, are credited with breaking racial barriers and transforming the medium into an artform and promotional tool. He helped propel the success of MTV and continued to innovate with videos for the albums Bad (1987), Dangerous (1991), HIStory: Past, Present and Future, Book I (1995), and Invincible (2001). Thriller became the best-selling album of all time, while Bad was the first album to produce five US Billboard Hot 100 number-one singles.\nFrom the late 1980s, Jackson became a figure of controversy and speculation due to his changing appearance, relationships, behavior, and lifestyle. In 1993, he was accused of sexually abusing the child of a family friend. The lawsuit was settled out of civil court; Jackson was not indicted due to lack of evidence. In 2005, he was tried and acquitted of further child sexual abuse allegations and several other charges. The FBI found no evidence of criminal conduct by Jackson in either case. In 2009, while he was preparing for a series of comeback concerts, This Is It, Jackson died from an overdose of propofol administered by his personal physician, Conrad Murray, who was convicted in 2011 of involuntary manslaughter. His death triggered reactions around the world, creating unprecedented surges of Internet traffic and a spike in sales of his music. A televised memorial service for Jackson, held at the Staples Center in Los Angeles, was viewed by more than an estimated 2.5 billion people globally.\nJackson is one of the best-selling music artists of all time, with estimated sales of over 400 million records worldwide.\n\nHe had 13 Billboard Hot 100 number-one singles (third highest of any artist in the Hot 100 era) and was the first artist to have a top-ten single in the Billboard Hot 100 in five different decades. His honors include 15 Grammy Awards, 6 Brit Awards, a Golden Globe Award, and 39 Guinness World Records, including the \"Most Successful Entertainer of All Time\". Jackson's inductions include the Rock and Roll Hall of Fame (twice), the Vocal Group Hall of Fame, the Songwriters Hall of Fame, the Dance Hall of Fame (the only recording artist to be inducted), and the Rhythm and Blues Music Hall of Fame.",

        "evidence": "Formula One cars are the fastest regulated road-course racing cars in the world, owing to very high cornering speeds achieved through the generation of large amounts of aerodynamic downforce. Much of this downforce is generated by front and rear wings, which have the side effect of causing severe turbulence behind each car. The turbulence reduces the downforce generated by the cars following directly behind, making it hard to overtake. Major changes made to the cars for the 2022 season has seen greater use of ground effect aerodynamics and modified wings to reduce the turbulence behind the cars, with the goal of making overtaking easier. The cars are dependent on electronics, aerodynamics, suspension and tyres. Traction control, launch control, and automatic shifting, plus other electronic driving aids, were first banned in 1994.

        "answer": "One major issue of CB filtering method is that the recommendation system is required to gain an understanding of user preferences for some sorts of items and deploy these for other sorts of items.",
        "evidence": "Today, Internet is one of the widest available media worldwide. It has essentially become a huge hit of data that has the potential to serve many information centric applications in our life. Recommendation system takes an essential part of many internet services and online applications, including applications like social-networking and recommendation of products (films, music, articles,..i.e.). Recommendation techniques have been used by the most known companies such as Amazon, Netflix and eBay to recommend releated items or products by estimating the probable preferences of customers. These techniques are profitable to both service provider and user. According to pervious works, two popular approaches for building recommendation systems can be categorized as content-based (CB), collaborative filtering (CF).\nContent-based (CB) recommending is adopted for recommendation systems model widely, which takes advantage of the property of items to create features and characteristics to coordinate user profiles. It can be relied on the properties of the items that each user likes to discover what else the user may like. One major issue of CB filtering method is that the recommendation system is required to gain an understanding of user preferences for some sorts of items and deploy these for other sorts of items.\nNevertheless CF has two widely known problems which are sparsity and cold start (CS). In the rating matrix, The percentage of elements which get values is small. Even it is possible that CF considers only a few rating for popular items. For instance, upon a considerable Netflix rating dataset which is provided for Netflix Prize competition, there are about 100 milion ratings for about 18,000 movies that are given by 480,000 users. The percentage of rating matrix elements which are received ratings is 1. With a sparse ranking matrix it is very challenging topic to make an effective recommendation, depending on estimation of the relationship between items and users. CS problem is another widely known issue for CF approach, which can occur on new users or items. In terms of achieving an effective recommendation, CF approach requires either ratings on an item or a large number of ratings from a user.\nRecently, researchers proposed various methods based on probabilistic topic modeling methods BIBREF0. LDA is a generative probabilistic model broadly used in the information retrieval field. Researchers have used topic modeling methods based on LDA for building recommendation systems in various subjects, including app recommendation BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, event recommendationBIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15, hashtag recommendation BIBREF16, BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21, BIBREF22, BIBREF23, BIBREF24, BIBREF25, BIBREF26, BIBREF27, BIBREF28, BIBREF29, BIBREF30, BIBREF31, BIBREF32, BIBREF33, BIBREF34, BIBREF35, BIBREF36, social networks and media BIBREF37, BIBREF38, BIBREF6, BIBREF9, BIBREF39, BIBREF40, BIBREF41. In this paper, We present a taxonomy of recommendation systems applications based on topic modeling (LDA) of the recent research and evaluate ISWC and WWW publications in computer science between 2013 to 2017 from DBLP dataset.\nOne major issue of CB filtering method is that the recommendation system is required to gain an understanding of user preferences for some sorts of items and deploy these for other sorts of items.",

        "question": "What are the general rules of the Baseball?",
        "evidence": "Baseball is played between two teams with nine players in the field from the team that is not batting at that point (the batting team would have one batter in play at \"home plate\" on the field). On a baseball field, the game is under the authority of several umpires. There are usually four umpires in major league games; up to six (and as few as one) may officiate depending on the league and the importance of the game. There are three bases. Numbered counterclockwise, first, second, and third bases are cushions (sometimes informally referred to as bags) shaped as 15 in (38 cm) squares which are raised a short distance above the ground; together with home plate, the fourth \"base\", they form a square with sides of 90 ft (27.4 m) called the diamond. Home plate is a pentagonal rubber slab 17 in (43.2 cm) wide. The playing field is divided into three main sections:\n\nThe infield, containing the four bases, is for general defensive purposes bounded by the foul lines and within the grass line (see figure).\nThe outfield is the grassed area beyond the infield grass line between the foul lines and bounded by a wall or fence.\nFoul territory is the entire area outside the foul lines.\nThe pitcher's mound is located in the center of the infield. It is an 18 ft (5.5 m) diameter mound of dirt no higher than 10 in (25.4 cm). Near the center of the mound is the pitching rubber, a rubber slab positioned 60 ft 6 in (18.4 m) from home plate. The pitcher must have one foot on the rubber at the start of every pitch to a batter, but the pitcher may leave the mound area once the ball is released.\n\nAt the college/professional level, baseball is played in nine innings in which each team gets one turn to bat and tries to score runs while the other pitches and defends in the field. High school baseball plays seven innings and Little League uses six-inning games. An inning is broken up into two halves in which the away team bats in the top (first) half, and the home team bats in the bottom (second) half. In baseball, the defense always has the ball—a fact that differentiates it from most other team sports. The teams switch every time the defending team gets three players of the batting team out. The winner is the team with the most runs after nine innings. If the home team is ahead after the top of the ninth, play does not continue into the bottom half. When this happens, an X is put on the scoreboard for the home team's score in the ninth inning. In the case of a tie, additional innings are played until one team comes out ahead at the end of an inning. If the home team takes the lead anytime during the bottom of the ninth or of any inning after that, play stops and the home team is declared the winner. This is known as a walk-off.\n\nThe basic contest is always between the pitcher for the fielding team and a batter. The pitcher throws—pitches—the ball towards home plate, where the catcher for the fielding team waits (in a crouched stance) to receive it. Behind the catcher stands the home plate umpire. The batter stands in one of the batter's boxes and tries to hit the ball with a bat. The pitcher must keep one foot in contact with the top or front of the pitcher's rubber—a 24×6 in (61×15 cm) plate located atop the pitcher's mound—during the entire pitch, so he can take only one step backward and one forward in delivering the ball. The catcher's job is to receive any pitches that the batter does not hit and to \"call\" the game by a series of hand movements that signal to the pitcher what pitch to throw and where. The catcher also usually signals the desired location of the ball within the strike zone and \"sets up\" behind the plate or holds his glove up in the desired location as a target. The catcher's role becomes more crucial depending on how the game is going, and how the pitcher responds to a given situation. Each pitch begins a new play, which might consist of nothing more than the pitch itself.\n\nEach half-inning, the goal of the defending team is to get three members of the other team out. A player who is out must leave the field and wait for his next turn at bat. There are many ways to get batters and baserunners out; some of the most common are catching a batted ball in the air, tag outs, force outs, and strikeouts. After the fielding team has put out three players from the opposing team, that half of the inning is over and the team in the field and the team at bat switch places; there is no upper limit to the number that may bat in rotation before three outs are recorded. Going through the entire order in an inning is referred to as \"batting around\" and it is indicative of a high-scoring inning. A complete inning consists of each opposing side having a turn (three outs) on offense.\n\nThe goal of the team at bat is to score more runs than the opposition; a player may do so by batting, then becoming a baserunner, touching all the bases in order (via one or more plays), and finally touching home plate. A player may also become a baserunner by being inserted as a pinch-runner. To that end, the goal of each batter is to enable baserunners to score or to become a baserunner himself. The batter attempts to hit the ball into fair territory—between the baselines—in such a way that the defending players cannot get them or the baserunners out. In general, the pitcher attempts to prevent this by pitching the ball in such a way that the batter cannot hit it cleanly or, ideally, at all.\n\nA baserunner who has successfully touched home plate without being retired (called out) after touching all previous bases scores a run. In an enclosed field, a fair ball hit over the fence on the fly is an automatic home run, which entitles the batter and all runners to touch all the bases and score. On a field with foul poles, a ball that hits a pole is also a home run. A home run hit with all bases occupied ('bases loaded') is called a grand slam.",
        "answer": "Baseball is a game contested between two teams of 9 players. The defense plays the field and has the ball, and the offense can score by batting the ball and making their way around the bases. The field consists of two parts, the infield, which contains the bases, and the outfield. The bases are 90 feet apart, arranged in diamond format, and advanced counterclockwise. The pitcher's mound is in the center of the infield and is 60 feet 6 inches away from home plate (where the batter stands to try and bat the ball). At the youth level, the bases may be placed as close as 60 feet apart, and the mound may be as close as 46 feet away. The infield contains 6 of the 9 defenders, the pitcher being on the pitcher's mound, the catcher positioned behind home plate to receive the ball from the pitcher, and 4 infielders. The 1st baseman and 2nd baseman are positioned on the right side of the infield near their respective bases. The shortstop and third baseman are positioned on the left side of the infield with the shortstop shaded closer to 2nd base, in a mirrored position from the 2nd baseman. The third baseman is positioned by third base. The outfielders are the 3 remaining defensive players positioned in the large grass outfield in a left, center, and right arrangement. The pitcher must deliver the ball over the plate at the height range of the player's knees to their torso. 3 pitches at this level or swings and misses count as an out. Balls batted that don't land in play, which the lines of play extend from the point of the home plate which is a 90-degree angle count as a strike as long it strikes one or two, a batter cannot foul out for the third strike. If a pitched ball is not called a strike it is a ball, and 4 balls in an at-bat award the batter first base via what is called a walk. Other ways to make outs are if a ball is batted and the fielders catch it before it hits the ground; if the ball hits the ground the runner can be declared out of the fielders touch the base of the advancing runner with possession of the ball prior to the runners' arrival, so long as the runner is forced to advance to the base. If there is no force, the runner must be tagged out. In the event of a fly-out, any runner must re-establish possession of the bag they started at and are not allowed to advance to the next base until the fielder catches the ball. If they don't re-establish possession of their originating base they can be called out if the ball and the fielder possessing it reaches the originating base before they do. 3 outs constitute a half-inning; after each half-inning, the teams rotate from offense to defense. After each team gets 3 outs the full inning is concluded. A game is complete after 9 innings, although youth games are usually 6 or 7 innings. If the teams are tied at the end of regulation, the teams will continuously add extra innings until the tie is broken. A ball that is batted over the outfield fence is considered a homerun and the batter and all base runners can advance safely to home. If a battled ball lands in fair territory and leaves the field of play, it is considered a ground-rule double, and all runners are awarded two bases from where they started. You can substitute players from your bench into the game at any time but players are not allowed to re-enter the game once substituted, so substitutions are done sparingly and strategically. Many leagues employ the designated hitter rule, which allows for a 10th player to bat in place of the pitcher. Balls, strikes, and outs are called by umpires, of which there can be anywhere between 2 and 4.",

The hierarchical semantic modeling learns different levels of granularity including word level, utterance level and conversation level. We then develop internal structured attention network on the linear-chain conditional random field (CRF) to specify structural dependencies in a soft manner. This approach generalizes the soft-selection attention on the structural CRF dependencies and takes into account the contextual influence on the nearing utterances.

Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach.",

        "evidence": "A lot of work has been done on detecting emotion in speech or visual data BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . But detecting emotions in textual data is a relatively new area that demands more research. There have been many attempts to detect emotions in text using conventional machine learning techniques and handcrafted features in which given the dataset, the authors try to find the best feature set that represents the most and the best information about the text, then passing the converted text as feature vectors to the classifier for training BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 , BIBREF19 , BIBREF20 , BIBREF21 , BIBREF22 , BIBREF23 , BIBREF24 , BIBREF25 , BIBREF26 . During the process of creating the feature set, in these methods, some of the most important information in the text such as the sequential nature of the data, and the context will be lost.\nConsidering the complexity of the task, and the fact that these models lose a lot of information by using simpler models such as the bag of words model (BOW) or lexicon features, these attempts lead to methods which are not reusable and generalizable. Further improvement in classification algorithms, and trying out new paths is necessary in order to improve the performance of emotion detection methods. Some suggestions that were less present in the literature, are to develop methods that go above lexical representations and consider the flow of the language.\nDue to this sequential nature, recurrent and convolutional neural networks have been used in many NLP tasks and were able to improve the performance in a variety of classification tasks BIBREF27 , BIBREF28 , BIBREF29 , BIBREF30 . There have been very few works in using deep neural network for emotion detection in text BIBREF31 , BIBREF32 . These models can capture the complexity an context of the language better not only by keeping the sequential information but also by creating hidden representation for the text as a whole and by learning the important features without any additional (and often incomplete) human-designed features.\nIn this work, we argue that creating a model that can better capture the context and sequential nature of text , can significantly improve the performance in the hard task of emotion detection. We show this by using a recurrent neural network-based classifier that can learn to create a more informative latent representation of the target text as a whole, and we show that this can improve the final performance significantly. Based on that, we suggest focusing on methodologies that increase the quality of these latent representations both contextually and emotionally, can improve the performance of these models. Based on this assumption we propose a deep recurrent neural network architecture to detect discrete emotions in a tweet dataset. The code can be accessed at GitHub [https://github.com/armintabari/Emotion-Detection-RNN].\nIn this work, we argue that creating a model that can better capture the context and sequential nature of text , can significantly improve the performance in the hard task of emotion detection.

From Table, the number and storage size of samples for our proposed method is much smaller than those used for SHOT. At test time, our method requires no computation for updating the model, which is at least on par with test-time adaptation methods since they can need additional backward passes for online adaptation.

        "question": "Given these paragraphs about Multiomics, what is panomics?",
        "evidence": "Multiomics, multi-omics, integrative omics, \"panomics\" or \"pan-omics\" is a biological analysis approach in which the data sets are multiple \"omes\", such as the genome, proteome, transcriptome, epigenome, metabolome, and microbiome (i.e., a meta-genome and/or meta-transcriptome, depending upon how it is sequenced); in other words, the use of multiple omics technologies to study life in a concerted way. By combining these \"omes\", scientists can analyze complex biological big data to find novel associations between biological entities, pinpoint relevant biomarkers and build elaborate markers of disease and physiology. In doing so, multiomics integrates diverse omics data to find a coherently matching geno-pheno-envirotype relationship or association. The OmicTools service lists more than 99 softwares related to multiomic data analysis, as well as more than 99 databases on the topic.\n\nSystems biology approaches are often based upon the use of panomic analysis data. The American Society of Clinical Oncology (ASCO) defines panomics as referring to \"the interaction of all biological functions within a cell and with other body functions, combining data collected by targeted tests ... and global assays (such as genome sequencing) with other patient-specific information.\"\n\nSingle-cell multiomics\nA branch of the field of multiomics is the analysis of multilevel single-cell data, called single-cell multiomics. This approach gives us an unprecedent resolution to look at multilevel transitions in health and disease at the single cell level. An advantage in relation to bulk analysis is to mitigate confounding factors derived from cell to cell variation, allowing the uncovering of heterogeneous tissue architectures.\n\nMethods for parallel single-cell genomic and transcriptomic analysis can be based on simultaneous amplification or physical separation of RNA and genomic DNA. They allow insights that cannot be gathered solely from transcriptomic analysis, as RNA data do not contain non-coding genomic regions and information regarding copy-number variation, for example. An extension of this methodology is the integration of single-cell transcriptomes to single-cell methylomes, combining single-cell bisulfite sequencing to single cell RNA-Seq. Other techniques to query the epigenome, as single-cell ATAC-Seq and single-cell Hi-C also exist.\n\nA different, but related, challenge is the integration of proteomic and transcriptomic data. One approach to perform such measurement is to physically separate single-cell lysates in two, processing half for RNA, and half for proteins. The protein content of lysates can be measured by proximity extension assays (PEA), for example, which use DNA-barcoded antibodies. A different approach uses a combination of heavy-metal RNA probes and protein antibodies to adapt mass cytometry for multiomic analysis.\n\nMultiomics and machine learning\nIn parallel to the advances in highthroughput biology, machine learning applications to biomedical data analysis are flourishing. The integration of multi-omics data analysis and machine learning has led to the discovery of new biomarkers. For example, one of the methods of the mixOmics project implements a method based on sparse Partial Least Squares regression for selection of features (putative biomarkers).\n\n\nhttps://en.wikipedia.org/wiki/Multiomics",

        "question": "Why do they set the keyword discovery task?",
        "answer": "To discover new keword that is most informative for existing keywords model training with respect.",
        "evidence": "Given a set of labeled and unlabeled microposts, our goal is to extract informative keywords and estimate their expectations in order to train a machine learning model. To achieve this goal, our proposed human-AI loop approach comprises two crowdsourcing tasks, i.e., micropost classification followed by keyword discovery, and a unified probabilistic model for expectation inference and model training. Figure FIGREF6 presents an overview of our approach. Next, we describe our approach from a process-centric perspective.\nFollowing previous studies BIBREF1, BIBREF17, BIBREF2, we collect a set of unlabeled microposts $\\mathcal {U}$ from a microblogging platform and post-filter, using an initial (set of) keyword(s), those microposts that are potentially relevant to an event category. Then, we collect a set of event-related microposts (i.e., positively labeled microposts) $\\mathcal {L}$, post-filtering with a list of seed events. $\\mathcal {U}$ and $\\mathcal {L}$ are used together to train a discriminative model (e.g., a deep neural network) for classifying the relevance of microposts to an event. We denote the target model as $p_\\theta (y|x)$, where $\\theta $ is the model parameter to be learned and $y$ is the label of an arbitrary micropost, represented by a bag-of-words vector $x$. Our approach iterates several times $t=\\lbrace 1, 2, \\ldots \\rbrace $ until the performance of the target model converges. Each iteration starts from the initial keyword(s) or the new keyword(s) discovered in the previous iteration. Given such a keyword, denoted by $w^{(t)}$, the iteration starts by sampling microposts containing the keyword from $\\mathcal {U}$, followed by dynamically creating micropost classification tasks and publishing them on a crowdsourcing platform.\nMicropost Classification. The micropost classification task requires crowd workers to label the selected microposts into two classes: event-related and non event-related. In particular, workers are given instructions and examples to differentiate event-instance related microposts and general event-category related microposts. Consider, for example, the following microposts in the context of Cyber attack events, both containing the keyword `hack':\nCredit firm Equifax says 143m Americans' social security numbers exposed in hack\nThis micropost describes an instance of a cyber attack event that the target model should identify. This is, therefore, an event-instance related micropost and should be considered as a positive example. Contrast this with the following example:\nCompanies need to step their cyber security up\nThis micropost, though related to cyber security in general, does not mention an instance of a cyber attack event, and is of no interest to us for event detection. This is an example of a general event-category related micropost and should be considered as a negative example.\nIn this task, each selected micropost is labeled by multiple crowd workers. The annotations are passed to our probabilistic model for expectation inference and model training.\nExpectation Inference & Model Training. Our probabilistic model takes crowd-contributed labels and the model trained in the previous iteration as input. As output, it generates a keyword-specific expectation, denoted as $e^{(t)}$, and an improved version of the micropost classification model, denoted as $p_{\\theta ^{(t)}}(y|x)$. The details of our probabilistic model are given in Section SECREF3.\nKeyword Discovery. The keyword discovery task aims at discovering a new keyword (or a set of keywords) that is most informative for model training with respect to existing keywords. To this end, we first apply the current model $p_{\\theta ^{(t)}}(y|x)$ on the unlabeled microposts $\\mathcal {U}$. For those that contain the keyword $w^{(t)}$, we calculate the disagreement between the model predictions and the keyword-specific expectation $e^{(t)}$:\nand select the ones with the highest disagreement for keyword discovery. These selected microposts are supposed to contain information that can explain the disagreement between the model prediction and keyword-specific expectation, and can thus provide information that is most different from the existing set of keywords for model training.\nFor instance, our study shows that the expectation for the keyword `hack' is 0.20, which means only 20% of the initial set of microposts retrieved with the keyword are event-related. A micropost selected with the highest disagreement (Eq. DISPLAY_FORM7), whose likelihood of being event-related as predicted by the model is $99.9\\%$, is shown as an example below:\nRT @xxx: Hong Kong securities brokers hit by cyber attacks, may face more: regulator #cyber #security #hacking https://t.co/rC1s9CB\nThis micropost contains keywords that can better indicate the relevance to a cyber security event than the initial keyword `hack', e.g., `securities', `hit', and `attack'.\nNote that when the keyword-specific expectation $e^{(t)}$ in Equation DISPLAY_FORM7 is high, the selected microposts will be the ones that contain keywords indicating the irrelevance of the microposts to an event category. Such keywords are also useful for model training as they help improve the model's ability to identify irrelevant microposts.\nTo identify new keywords in the selected microposts, we again leverage crowdsourcing, as humans are typically better than machines at providing specific explanations BIBREF18, BIBREF19. In the crowdsourcing task, workers are first asked to find those microposts where the model predictions are deemed correct. Then, from those microposts, workers are asked to find the keyword that best indicates the class of the microposts as predicted by the model. The keyword most frequently identified by the workers is then used as the initial keyword for the following iteration. In case multiple keywords are selected, e.g., the top-$N$ frequent ones, workers will be asked to perform $N$ micropost classification tasks for each keyword in the next iteration, and the model training will be performed on multiple keyword-specific expectations.\nThe keyword discovery task aims at discovering a new keyword (or a set of keywords) that is most informative for model training with respect to existing keywords.",

The malting process renders the grain usable to the brewer. It's basically taking a live seed, steeping it in water and tricking it into thinking it's time to grow.\" The grain starts to ready itself to grow into a plant but the germination is then stopped by drying the barley. Malting helps to create the enzymes necessary to convert the starches present in the seeds into sugars. Without malting, the beer would not have enough sugar content to properly ferment.\n\nThe malted barley is crushed or milled and then soaked in warm water in order to create a sugar solution known as wort. Any other grains used in the brewing process are also added at this point. Soaking the grains in warm water helps to further convert the starches into the sugars necessary for fermentation.\n\nThe wort is then moved to a copper pot and boiled. During boiling, some of the water in the wort evaporates, leaving behind a higher concentration of sugars. Boiling also helps to sterilize the mixture in preparation for fermentation. \n\nAfter boiling, the solid hops and grain are removed, and the mixture is cooled. The brewers then add yeast to this mixture. Fermenting with yeast is what makes beer alcoholic. The time it takes to ferment a beer varies based on type of yeast and style of fermentation, but most beers take about a week to ferment.\n\nDifferent strains of yeast and different fermentation techniques determine what kind of beer is being made and how it will taste. For example, when making a lager, the yeast ferments at the bottom of the wort at a cooler temperature. Ales are made with a different strain of yeast, and top fermented at warmer temperatures. After fermentation, the beer is then cooled again before bottling or canning.",

He'd ascend from a loping, bounce-filled run-up to the wicket and hurl the ball with considerable ostentation.\n\nQadir had many typical leg-spin presentations that changed the ball's trajectory and turn to enchant a wide range of combinations.\n\nHe bowled the top spinner and the flipper with tremendous precision and effect, and he had at least two different googlies. He frequently had too many options and employed too much diversity, rather than building a rhythm.\n\n4. Richie Benaud\n\nRichie Benaud was known as the \"Voice of Cricket.\" He came to personify the game in all of its guises, from batter to captain to writer to pundit to thinker!\n\nHe is considered one of cricket's all-time greats, second only to Sir Donald Bradman. Benaud is the only all-rounder on this list, as well as the only all-rounder who bowls spin.\n\n5. Mushtaq Ahmed\n\nMushtaq Ahmed is another Pakistani star who has made our list.\n\nHe modelled his persona after Intikhab Alam and Abdul Qadir. Mushtaq was an outstanding bowler with a fiery tenacity. During a brief but energetic run-up to the wicket, the ball was delivered with a misty whirling of arms.\n\nHe would implore the umpire for a favourable verdict with frenzied and wild appeals, and he would become visibly discouraged if the umpire ignored his straighter one or googly or allowed a batsman to escape despite intended padding.",

The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources, and from grey, brown or black hydrogen, which is obtained from fossil sources or from the electrolysis of water. Natural hydrogen may be renewable, non-polluting and allows for lower cost operation compared to industrial hydrogen. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.\n\nOrigin of natural hydrogen\nThere are several sources of natural hydrogen:\n\n- degassing of deep hydrogen from the Earth's crust and mantle;\n- reaction of water with ultrabasic rocks (serpentinisation);\n- contact of water with reducing agents in the Earth's mantle;\n- interaction of water with freshly exposed rock surfaces (weathering);\n- decomposition of hydroxyl ions in the structure of minerals;\n- Natural radiolysis of water;\n- decomposition of organic matter;\n- biological activity\n- Extraction\n- Natural hydrogen is extracted from wells, mixed with other gases such as nitrogen or helium.\n\nSeveral sources have been identified in France. Geologists Alain Prinzhofer and Eric Derville have demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States. However, their potential remains difficult to assess.\n\nNumerous emanations on the ocean floor have been identified but are difficult to exploit. The discovery of a significant emergence in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.\n\nGeology\nNatural hydrogen is generated continuously from a variety of natural sources. There are many known hydrogen emergences on mid-ocean ridges. Another of the known reactions, serpentinisation, occurs under the sea floor (in the oceanic crust).\n\nDiagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably in Russia. Other sources are being explored, such as mantle hydrogen, or hydrogen from radiolysis (natural electrolysis) or from bacterial activity. In France, the Alps and Pyrenees are suitable for exploitation. New Caledonia has hyperalkaline sources that show dihydrogen emissions. A large accumulation of natural hydrogen was discovered in Bourakebougou (Mali).\n\nCharacteristics\nDihydrogen is very soluble in fresh water, especially at depth (solubility increases with pressure).\n\nhttps://en.wikipedia.org/wiki/Natural_hydrogen",

        "question": "What is a medical search engine?",
        "answer": "An essential component for many online medical applications.",
        "evidence": "Medical search engines are an essential component for many online medical applications, such as online diagnosis systems and medical document databases. A typical online diagnosis system, for instance, relies on a medical search engine. The search engine takes as input a user query that describes some symptoms and then outputs clinical concept entries that provide relevant information to assist in diagnosing the problem. One challenge medical search engines face is the segmentation of individual clinical entities. When a user query consists of multiple clinical entities, a search engine would often fail to recognize them as separate entities. For example, the user query “fever joint pain weight loss headache” contains four separate clinical entities: “fever”, “joint pain”, “weight loss”, and “headache”. But when the search engine does not recognize them as separate entities and proceeds to retrieve results for each word in the query, it may find \"pain\" in body locations other than \"joint pain\", or it may miss \"headache\" altogether, for example. Some search engines allow the users to enter a single clinical concept by selecting from an auto-completion pick list. But this could also result in retrieving inaccurate or partial results and lead to poor user experience.\nWe want to improve the medical search engine so that it can accurately retrieve all the relevant clinical concepts mentioned in a user query, where relevant clinical concepts are defined with respect to the terminologies the search engine uses. The problem of extracting clinical concept mentions from a user query can be seen as a variant of the Concept Extraction (CE) task in the frequently-cited NLP challenges in healthcare, such as 2010 i2b2/VA BIBREF0 and 2013 ShARe/CLEF Task 1 BIBREF1. Both CE tasks in 2010 i2b2/VA and 2013 ShARe/CLEF Task 1 ask the participants to design an algorithm to tag a set of predefined entities of interest in clinical notes. These entity tagging tasks are also known as clinical Named Entity Recognition (NER). For example, the CE task in 2010 i2b2/VA defines three types of entities: “problem”, “treatment”, and “test”. The CE task in 2013 ShARe/CLEF defines various types of disorder such as “injury or poisoning”, \"disease or syndrome”, etc. In addition to tagging, the CE task in 2013 ShARe/CLEF has an encoding component which requires selecting one and only one Concept Unique Identifier (CUI) from Systematized Nomenclature Of Medicine Clinical Terms (SNOMED-CT) for each disorder entity tagged. Our problem, similar to the CE task in 2013 ShARe/CLEF, also contains two sub-problems: tagging mentions of entities of interest (entity tagging), and selecting appropriate terms from a glossary to match the mentions (term matching). However, several major differences exist. First, compared to clinical notes, the user queries are much shorter, less technical, and often less coherent. Second, instead of encoding, we are dealing with term matching where we rank a few best terms that match an entity, instead of selecting only one. This is because the users who type the queries may not have a clear idea about what they are looking for, or could be laymen who know little terminology, it may be more helpful to provide a set of likely results and let the users choose. Third, the types of entities are different. Each medical search engine may have its own types of entities to tag. There is also one minor difference in the tagging scheme between our problem and the CE task in 2013 ShARe/CLEF - We limit our scope to dealing with entities of consecutive words and not disjoint entities . We use only Beginning, Inside, Outside (BIO) tags. Given the differences listed above, we need to customize a framework consisting of an entity tagging and term matching component for our CE problem.\nMedical search engines are an essential component for many online medical applications, such as online diagnosis systems and medical document databases.",

I don't think this day will last long. We should understand the the horror of exponential growth in AI computing power. There's a term for bootstrapping, which describes the situation where the AI can upgrade itself. In a very important area of computing, the compiler, it has long implemented bootstrapping. Writing a simple compiler in assembly language, and then using a simple compiler to implement a compiler capable of handling more complex syntax, has resulted in our current high-level language compilers, such as the C language compiler. I think ChatGPT is likely to follow the same path.\n\nBy then, it was hard for me to imagine how far AI could go, but now I think the biggest concern is that people are becoming addicted to using ChatGPT. I can't help but use it for answers and inspiration. This leads to the terrible problem that human beings themselves become lazy in their thinking.

        "answer": "Deciding if a sentence should be included in the summary.",
        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary",

When Rouge was proposed, the original variants were only recall-oriented and hence the reported correlation results BIBREF1 . The later extension of Rouge family by precision were only reflected in the later versions of the Rouge toolkit and additional evaluation of its effectiveness was not reported. Nevertheless, later published work in summarization adopted this toolkit for its ready implementation and relatively efficient performance.\nThe original Rouge metrics show high correlations with human judgments of the quality of summaries on the DUC 2001-2003 benchmarks. However, these benchmarks consist of newswire data and are intrinsically very different than other summarization tasks such as summarization of scientific papers.

        "answer": "In legal parlance, laches is a defense which when raised implies the plaintiff caused inordinate delay, was part of the act of which it complains or caused prejudice to a defendant due to any delay. The Statute of Limitations is a common example of laches where a plaintiff is precluded from bringing an action due to inordinate delay.\n\nA defense of waiver claims that the plaintiff knowingly and intentionally signed away, relinquished or otherwise abandoned the right which it claims was violated by the defendant. A common example of a waiver is when one engages in a dangerous act for pleasure such as sky diving or rock climbing. The instructor or facility would have the purchaser sign a waiver for bodily harm suffered from engaging in the dangerous act.\n\nBoth defenses are affirmative defenses and must be raised for them to take effect. It is important to note that affirmative defenses can themselves fall to laches and waiver.",

        "evidence": "Moreover, QA and QG have probabilistic correlation as both tasks relate to the joint probability between $q$ and $a$ . Given a question-answer pair $\\langle q, a \\rangle $ , the joint probability $P(q, a)$ can be computed in two equivalent ways.\n$$P(q, a) = P(a) P(q|a) = P(q)P(a|q)$$ (Eq. 1)\nThe conditional distribution $P(q|a)$ is exactly the QG model, and the conditional distribution $P(a|q)$ is closely related to the QA model.

There might be different ways of exploiting the duality of QA and QG. In this work, we leverage the probabilistic correlation between QA and QG as the regularization term to influence the training process of both tasks. Specifically, the training objective of our framework is to jointly learn the QA model parameterized by $\\theta _{qa}$ and the QG model parameterized by $\\theta _{qg}$ by minimizing their loss functions subject to the following constraint.\n$$P_a(a) P(q|a;\\theta _{qg}) = P_q(q)P(a|q;\\theta _{qa})$$ (Eq. 3)\n$P_a(a)$ and $P_q(q)$ are the language models for answer sentences and question sentences, respectively.\nWe describe the proposed algorithm in this subsection. Overall, the framework includes three components, namely a QA model, a QG model and a regularization term that reflects the duality of QA and QG. Accordingly, the training objective of our framework includes three parts, which is described in Algorithm 1.\nThe QA specific objective aims to minimize the loss function $l_{qa}(f_{qa}(a,q;\\theta _{qa}), label)$ , where $label$ is 0 or 1 that indicates whether $a$ is the correct answer of $q$ or not. Since the goal of a QA model is to predict whether a question-answer pair is correct or not, it is necessary to use negative QA pairs whose labels are zero. The details about the QA model will be presented in the next section.\nFor each correct question-answer pair, the QG specific objective is to minimize the following loss function,\n$$l_{qg}(q, a) = -log P_{qg}(q|a;\\theta _{qg})$$ (Eq. 6)\nwhere $a$ is the correct answer of $q$ . The negative QA pairs are not necessary because the goal of a QG model is to generate the correct question for an answer. The QG model will be described in the following section.\nThe third objective is the regularization term which satisfies the probabilistic duality constrains as given in Equation 3 . Specifically, given a correct $\\langle q, a \\rangle $ pair, we would like to minimize the following loss function,\n$$ \\nonumber l_{dual}(a,q;\\theta _{qa}, \\theta _{qg}) &= [logP_a(a) + log P(q|a;\\theta _{qg}) \\\\ & - logP_q(q) - logP(a|q;\\theta _{qa})]^2$$ (Eq. 9)\nwhere $P_a(a)$ and $P_q(q)$ are marginal distributions, which could be easily obtained through language model. $P(a|q;\\theta _{qg})$ could also be easily calculated with the markov chain rule: $P(q|a;\\theta _{qg}) = \\prod _{t=1}^{|q|} P(q_t|q_{<t}, a;\\theta _{qg})$ , where the function $P(q_t|q_{<t}, a;\\theta _{qg})$ is the same with the decoder of the QG model (detailed in the following section).\nMoreover, QA and QG have probabilistic correlation as both tasks relate to the joint probability between $q$ and $a$ .

        "answer": "Gigaword dataset and CNN dataset.",
        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nFor this purpose, we use the development sets of the Gigaword dataset provided in and of the CNN dataset provided in as the experimental data for quantitative evidence and refer the readers to Figure 1 as the running example.",

        "answer": "To analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories.",
        "evidence": "Cancer is one of the leading causes of death in the world, with over 80,000 deaths registered in Canada in 2017 (Canadian Cancer Statistics 2017). A computer-aided system for cancer diagnosis usually involves a pathologist rendering a descriptive report after examining the tissue glass slides obtained from the biopsy of a patient. A pathology report contains specific analysis of cells and tissues, and other histopathological indicators that are crucial for diagnosing malignancies. An average sized laboratory may produces a large quantity of pathology reports annually (e.g., in excess of 50,000), but these reports are written in mostly unstructured text and with no direct link to the tissue sample. Furthermore, the report for each patient is a personalized document and offers very high variability in terminology due to lack of standards and may even include misspellings and missing punctuation, clinical diagnoses interspersed with complex explanations, different terminology to label the same malignancy, and information about multiple carcinoma appearances included in a single report BIBREF0 .\nIn Canada, each Provincial and Territorial Cancer Registry (PTCR) is responsible for collecting the data about cancer diseases and reporting them to Statistics Canada (StatCan). Every year, Canadian Cancer Registry (CCR) uses the information sources of StatCan to compile an annual report on cancer and tumor diseases. Many countries have their own cancer registry programs. These programs rely on the acquisition of diagnostic, treatment, and outcome information through manual processing and interpretation from various unstructured sources (e.g., pathology reports, autopsy/laboratory reports, medical billing summaries). The manual classification of cancer pathology reports is a challenging, time-consuming task and requires extensive training BIBREF0 .\nWith the continued growth in the number of cancer patients, and the increase in treatment complexity, cancer registries face a significant challenge in manually reviewing the large quantity of reports BIBREF1 , BIBREF0 . In this situation, Natural Language Processing (NLP) systems can offer a unique opportunity to automatically encode the unstructured reports into structured data. Since, the registries already have access to the large quantity of historically labeled and encoded reports, a supervised machine learning approach of feature extraction and classification is a compelling direction for making their workflow more effective and streamlined. If successful, such a solution would enable processing reports in much lesser time allowing trained personnel to focus on their research and analysis. However, developing an automated solution with high accuracy and consistency across wide variety of reports is a challenging problem.\nFor cancer registries, an important piece of information in a pathology report is the associated ICD-O code which describes the patient's histological diagnosis, as described by the World Health Organization's (WHO) International Classification of Diseases for Oncology BIBREF2 . Prediction of the primary diagnosis from a pathology report provides a valuable starting point for exploration of machine learning techniques for automated cancer surveillance. A major application for this purpose would be “auto-reporting” based on analysis of whole slide images, the digitization of the biopsy glass slides. Structured, summarized and categorized reports can be associated with the image content when searching in large archives. Such as system would be able to drastically increase the efficiency of diagnostic processes for the majority of cases where in spite of obvious primary diagnosis, still time and effort is required from the pathologists to write a descriptive report.\nThe primary objective of our study is to analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories. We demonstrate that TF-IDF feature vectors combined with linear SVM or XGBoost classifier can be an effective method for classification of the reports, achieving up to 83% accuracy. We also show that TF-IDF features are capable of identifying important keywords within a pathology report. Furthermore, we have created a new dataset consisting of 1,949 pathology reports across 37 primary diagnoses. Taken together, our exploratory experiments with a newly introduced dataset on pathology reports opens many new opportunities for researchers to develop a scalable and automatic information extraction from unstructured pathology reports.\nThe primary objective of our study is to analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories.",

The results on the UEA datasets are summarized in   estimation and cross-entropy as approximations, we get the criteria in Eq. (). To empirically verify the effectiveness of the proposed criteria, we adopt the dataset CricketX from the UCR archive, and conduct augmentations with different configurations, such as jittering with noise from N (0, 0.3) and cutout 10% time stamps. For each configuration, we calculate the criteria score and the corresponding classification accuracy within the setting in Section 4.2. As shown in Figure, in general, accuracy performance is positively related to the proposed criteria in both supervised and unsupervised settings, verifying the correctness of using the criteria as the objective in the meta-network training.\nUnder the purely unsupervised setting, InfoTS preserves fidelity by adopting one-hot encoding as the pseudo labels.",

Crowe portrays Roman general Maximus Decimus Meridius, who is betrayed when Commodus, the ambitious son of Emperor Marcus Aurelius, murders his father and seizes the throne. Reduced to slavery, Maximus becomes a gladiator and rises through the ranks of the arena to avenge the murders of his family and his emperor.",
        "answer": "In 180 AD, Hispano-Roman General Maximus Decimus Meridius intends to return home after he leads the Roman army to victory against the Germanic tribes near Vindobona on the Limes Germanicus. Emperor Marcus Aurelius tells Maximus that his own son, Commodus, is unfit to rule and that he wishes Maximus to succeed him, as regent, to help save Rome from corruption and restore the republic. When told of this, Commodus privately murders his father.\n\nCommodus proclaims himself the new emperor, asking Maximus for his loyalty, but he refuses. Maximus is arrested by the Praetorian Guard and is told that he and his family will die. He kills his captors and, wounded, rides for his home near Turgalium (now Trujillo), where he finds his wife and son crucified. Maximus buries them, then collapses from his injuries. Slavers find him, and take him to the city of Zucchabar in the Roman province of Mauretania Caesariensis, where he is sold to gladiator trainer Proximo.\n\nMaximus reluctantly fights in local tournaments, his combat skills helping him win matches and gain popularity. He befriends two other gladiators: Hagen, a German; and Juba, a Numidian. Proximo reveals to Maximus that he was once a gladiator who was freed by Marcus Aurelius, and advises him to \"win the crowd\" to win his freedom.\n\nWhen Commodus organises 150 days of games to commemorate his father's death, Proximo takes his gladiators to Rome to fight in the Colosseum. Disguised in a masked helmet, Maximus debuts in the Colosseum as a Carthaginian in a re-enactment of the Battle of Zama. Unexpectedly, he leads his side to victory, and Commodus enters the Colosseum to offer his congratulations. He orders the disguised Maximus, as leader of the gladiators, to reveal his identity; Maximus removes his helmet and declares vengeance. Commodus is compelled by the crowd to let the gladiators live, and his guards are held back from striking them down.\n\nMaximus's next fight is against a legendary undefeated gladiator, Tigris of Gaul. Commodus arranges for several tigers to be set upon Maximus during the duel, but Maximus manages to prevail. Commodus orders Maximus to kill Tigris, but Maximus spares his opponent's life; in response, the crowd chants \"Maximus the Merciful\", angering Commodus.\n\nMaximus discovers from Cicero, his ex-orderly, that his former legions remain loyal. He meets in secret with Lucilla, Commodus's sister and once the lover of Maximus; and Gracchus, an influential senator. They agree to have Maximus escape Rome to join his legions, topple Commodus by force, and hand power back to the Roman Senate. Commodus learns of the plot when Lucilla's son, Lucius, innocently hints at the conspiracy. Commodus threatens Lucilla and Lucius, and has the Praetorian Guard arrest Gracchus and attack the gladiators' barracks. Proximo and his men, including Hagen, sacrifice themselves to enable Maximus to escape. Maximus is captured at the rendezvous with Cicero, where the latter is killed.\n\nIn an effort to win back public approval, Commodus challenges Maximus to a duel in the Colosseum. He stabs Maximus in the lung before the match to gain an advantage. Despite his injuries, Maximus disarms Commodus. After the Praetorian Guard refuses to aid him, Commodus unsheathes a hidden knife; Maximus overpowers Commodus and drives the knife into his throat, killing him. Before Maximus succumbs to his wounds, he asks for political reforms, for his gladiator allies to be freed, and for Senator Gracchus to be reinstated. As he dies, he has a vision where he reunites with his wife and son. His friends and allies honor him as \"a soldier of Rome\", at Lucilla's behest, and carry his body out of the arena, while the body of Commodus is left behind.\n\nThat night, Juba visits the Colosseum and buries figurines of Maximus's wife and son at the spot where he died.",

        "answer": "Yes, it does.",
        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nExperiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.",

Even though the dataset is on the small size, it is, to the best of our knowledge, the first of this kind.\nAn issue with the method that we used to construct our new dataset of entailment problems is that it is difficult to scale: it demands several minutes of scarce expert work per constructed problem. Our plan is to investigate the possibility to gamify the process, so that lots of people can participate in the construction of precise entailment problems, as a form of entertainment. We leave any detail to further work, but this would be an asymmetric game, where one one player tries construct watertight entailment problems, and the opposing player would try and refute such entailment problems (say, by giving counter-examples). Identifying the possible kind of mistakes, as we have done here, will help prompting the players about things to look for — in either of the possible roles.\nFinally we find it striking that many mistakes committed in RTE are falling for classical fallacies (appealing to authority accounts for more than a quarter of errors). Thus, we believe that while the entailment problems are useful for the construction of NLI systems, the added hypotheses (or moves taken in our hypothetical game) could be of interest to the linguistic community at large.\nWe find that our hypothesis is validated: RTE is not suitable as such to test a precise NLI system, because, for entailment to hold as tagged in RTE, much world-knowledge is required and many missing hypotheses are omitted.",

        "evidence": "Our work is related to three lines of research: Sequence labeling, Adversarial training, and Crowdsourcing.\nSequence labeling. NER is widely treated as a sequence labeling problem, by assigning a unique label over each sentential word BIBREF9 . Early studies on sequence labeling often use the models of HMM, MEMM, and CRF BIBREF10 based on manually-crafted discrete features, which can suffer the feature sparsity problem and require heavy feature engineering. Recently, neural network models have been successfully applied to sequence labeling BIBREF1 , BIBREF11 , BIBREF2 . Among these work, the model which uses Bi-LSTM for feature extraction and CRF for decoding has achieved state-of-the-art performances BIBREF11 , BIBREF2 , which is exploited as the baseline model in our work.\nAdversarial Training. Adversarial Networks have achieved great success in computer vision such as image generation BIBREF12 , BIBREF13 . In the NLP community, the method is mainly exploited under the settings of domain adaption BIBREF14 , BIBREF7 , cross-lingual BIBREF15 , BIBREF6 and multi-task learning BIBREF16 , BIBREF17 . All these settings involve the feature divergences between the training and test examples, and aim to learn invariant features across the divergences by an additional adversarial discriminator, such as domain discriminator. Our work is similar to these work but is applies on crowdsourcing learning, aiming to find invariant features among different crowdsourcing workers.\nCrowdsourcing. Most NLP tasks require a massive amount of labeled training data which are annotated by experts. However, hiring experts is costly and non-scalable, both in terms of time and money. Instead, crowdsourcing is another solution to obtain labeled data at a lower cost but with relative lower quality than those from experts. BIBREF18 snow2008cheap collected labeled results for several NLP tasks from Amazon Mechanical Turk and demonstrated that non-experts annotations were quite useful for training new systems. In recent years, a series of work have focused on how to use crowdsourcing data efficiently in tasks such as classification BIBREF19 , BIBREF20 , and compare quality of crowd and expert labels BIBREF21 .\nIn sequence labeling tasks, BIBREF22 dredze2009sequence viewed this task as a multi-label problem while BIBREF3 rodrigues2014sequence took workers identities into account by assuming that each sentential word was tagged correctly by one of the crowdsourcing workers and proposed a CRF-based model with multiple annotators. BIBREF4 nguyen2017aggregating introduced a crowd representation in which the crowd vectors were added into the LSTM-CRF model at train time, but ignored them at test time. In this paper, we apply adversarial training on crowd annotations on Chinese NER in new domains, and achieve better performances than previous studies on crowdsourcing learning.\nOur work is related to three lines of research: Sequence labeling, Adversarial training, and Crowdsourcing.",

        "question": "How about the correlations between Rouge and the Pyramid scores?",
        "answer": "The correlations are weak, which challenges its effectiveness for scientific summarization.",
        "evidence": "Automatic text summarization has been an active research area in natural language processing for several decades. To compare and evaluate the performance of different summarization systems, the most intuitive approach is assessing the quality of the summaries by human evaluators. However, manual evaluation is expensive and the obtained results are subjective and difficult to reproduce BIBREF0 . To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nResults reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization.",

        "evidence": "In most other analyses and datasets, the idea of out-of-scope data is not considered, and instead the output classes are intended to cover all possible queries (e.g., TREC BIBREF7). Recent work by BIBREF8 considers a similar problem they call out-of-distribution detection. They use other datasets or classes excluded during training to form the out-of-distribution samples. This means that the out-of-scope samples are from a small set of coherent classes that differ substantially from the in-distribution samples. Similar experiments were conducted for evaluating unknown intent discovery models in BIBREF9. In contrast, our out-of-scope queries cover a broad range of phenomena and are similar in style and often similar in topic to in-scope queries, representing things a user might say given partial knowledge of the capabilities of a system.\nTable TABREF20 compares our dataset with other short-query intent classification datasets. The Snips BIBREF0 dataset and the dataset presented in BIBREF10 are the most similar to the in-scope part of our work, with the same type of conversational agent requests. Like our work, both of these datasets were bootstrapped using crowdsourcing. However, the Snips dataset has only a small number of intents and an enormous number of examples of each. Snips does present a low-data variation, with 70 training queries per intent, in which performance drops slightly. The dataset presented in BIBREF10 has a large number of intent classes, yet also contains a wide range of samples per intent class (ranging from 24 to 5,981 queries per intent, and so is not constrained in all cases).\nBIBREF11 created datasets with constrained training data, but with very few intents, presenting a very different type of challenge.

        "evidence": "We evaluate the performance of our model on two high-quality datasets: Switchboard Dialogue Act Corpus (SwDA) BIBREF4 and DailyDialog BIBREF24. SwDA has been widely used in previous work for the DA recognition task. It is annotated on 1155 human to human telephonic conversations about the given topic. Each utterance in the conversation is manually labeled as one of 42 dialogue acts according to SWBD-DAMSL taxonomy BIBREF25. In BIBREF10, they used 43 categories of dialogue acts, which is different from us and previous work. The difference in the number of labels is mainly due to the special label “+”, which represents that the utterance is interrupted by the other speaker (and thus split into two or more parts). We used the same processing with BIBREF26, which concatenated the parts of an interrupted utterance together, giving the result the tag of the first part and putting it in its place in the conversation sequence. It is critical for fair comparison because there are nearly 8% data has the label “+”. Lacking standard splits, we followed the training/validation/test splits by BIBREF14. DailyDialog dataset contains 13118 multi-turn dialogues, which mainly reflect our daily communication style. It covers various topics about our daily life. Each utterance in the conversation is manually labeled as one out of 4 dialogue act classes. Table TABREF18 presents the statistics for both datasets. In our preprocessing, the text was lowercased before tokenized, and then sentences were tokenized by WordPiece tokenizer BIBREF27 with a 30,000 token vocabulary to alleviate the Out-of-Vocabulary problem.\nIn this section, we evaluate the proposed approaches on SwDA dataset. Table TABREF20 shows our experimental results and the previous ones on SwDA dataset. It is worth noting that BIBREF10 combined GloVeBIBREF28 and pre-trained ELMo representationsBIBREF29 as word embeddings. However, in our work, we only applied the pre-trained word embedding. To illustrate the importance of context information, we also evaluate several sentence classification methods (CNN, LSTM, BERT) as baselines. For baseline models, both CNN and LSTM, got similar accuracy (75.27% and 75.59% respectively). We also fine-tuned BERT BIBREF30 to do recognition based on single utterance. As seen, with the powerful unsupervised pre-trained language model, BERT (76.88% accuracy) outperformed LSTM and CNN models for single sentence classification. However, it was still much lower than the models based on context information. It indicates that context information is crucial in the DA recognition task. BERT can boost performance in a large margin. However, it costs too much time and resources. In this reason, we chose LSTM as our utterance encoder in further experiment.\nFLOAT SELECTED: Table 4: Comparison results with the previous approaches and our approaches on SwDA dataset.\nFLOAT SELECTED: Table 5: Experiment results about the hyperparameter W and P on SwDA dataset and online prediction result. W,P indicate the size of sliding window and context padding length during training and testing.\nFLOAT SELECTED: Table 6: Experiment results on DailyDialog dataset.\nTo further illustrate the effect of the context length, we also performed experiments with different sliding window $W$ and context padding $P$. Table TABREF22 shows the result. It is worth noting that it is actually the same as single sentence classification when $P = 0$ (without any context provided). First, we set $W$ to 1 to discuss how the length of context padding will affect. As seen in the result, the accuracy increased when more context padding was used for both LSTM+BLSTM and LSTM+Attention approaches, so we did not evaluate the performance of LSTM+LC Attention when context padding is small. There was no further accuracy improvement when the length of context padding was beyond 5. Therefore, we fixed the context padding length $P$ to 5 and increased the size of the sliding window to see how it works. With sliding window size increasing, the more context was involved together with more unnecessary information. From the experiments, we can see that both LSTM+BLSTM and LSTM+Attention achieved the best performance when window size was 1 and context padding length was 5. When window size increased, the performances of these two models dropped. However, our model (LSTM+LC Attention) can leverage the context information more efficiently, which achieved the best performance when window size was 10, and the model was more stable and robust to the different setting of window size.\nThe classification accuracy of DailyDialog dataset is summarized in Table TABREF23. As for sentence classification without context information, the fine-tuned BERT still outperformed LSTM and CNN based models. From table TABREF18 we can see that, the average dialogue length $|U|$ in DailyDialog is much shorter than the average length of SwDA. So, in our experiment, we set the maximum of the $W$ to 10, which almost covers the whole utterances in the dialogue. Using the same way as SwDA dataset, we, first, set W to 1 and increased the length of context padding. As seen, modeling local context information, hierarchical models yielded significant improvement than sentence classification. There was no further accuracy improvement when the length of context padding was beyond 2, so we fixed the context padding length P to 2 and increased the size of sliding window size W. From the experiments, we can see that LSTM+Attention always got a little better accuracy than LSTM+BLSTM. With window size increasing, the performances of these two models dropped. Relying on modeling local contextual information, LSTM+LC Attention achieved the best accuracy (85.81%) when the window size was 5. For the longer sliding window, the performance of LSTM+LC Attention was still better and more robust than the other two models. For online prediction, we added 2 preceding utterances as context padding, and the experiment shows that LSTM+LC Attention outperformed the other two models under the online setting, although the performances of these three models dropped without subsequent utterances.\nWe evaluate the performance of our model on two high-quality datasets: Switchboard Dialogue Act Corpus (SwDA) BIBREF4 and DailyDialog BIBREF24. \nIn this section, we evaluate the proposed approaches on SwDA dataset. Table TABREF20 shows our experimental results and the previous ones on SwDA dataset. \nFLOAT SELECTED: Table 4: Comparison results with the previous approaches and our approaches on SwDA dataset.\nFLOAT SELECTED: Table 5: Experiment results about the hyperparameter W and P on SwDA dataset and online prediction result.

Q(2) Does PRIME reduce the total simulation time compared to other methods? Q(3) Can PRIME produce hardware accelerators for a family of different applications? Q(4) Can PRIME trained for a family of applications extrapolate to designing a high-performing accelerator for a new, unseen application, thereby enabling data reuse? Additionally, we ablate various properties of PRIME (Appendix A.6) and evaluate its efficacy in designing accelerators with distinct dataflow architectures, with a larger search space (up to 2.5×10 114 possible candidates).\nBaselines and comparisons. We compare PRIME against three online optimization methods that actively query the simulator: (1) evolutionary search with the firefly optimizer (Yazdanbakhsh et al., 2021a) (\"Evolutionary\"), which is the shown to outperform other online methods for accelerator design; (2) Bayesian Optimization (\"Bayes Opt\"), (3) MBO. In all the experiments, we grant all the methods the same number of feasible points. Note that our method do not get to select these points, and use the same exact offline points across all the runs, while the online methods can actively select which points to query, and therefore require new queries for every run. \"D(Best in Training)\" denotes the best latency value in the training dataset used in PRIME. We also present ablation results with different components Architecting application-specific accelerators. We first evaluate PRIME in designing specialized accelerators for each of the applications in Table. We train a conservative surrogate using the method in Section 4 on the logged dataset for each application separately. The area constraint α (Equation) is set to α = 29 mm 2 , a realistic budget for accelerators. Table summarizes the results. On average, the best accelerators designed by PRIME outperforms the best accelerator configuration in the training dataset (last row Table), by 2.46×. PRIME also outperforms the accelerators in the best online method by 1.54× (up to 5.80× and 6.62× in t-RNN Dec and t-RNN Enc, respectively). Moreover, perhaps surprisingly, PRIME generates accelerators that are better than all the online optimization methods in 7/9 domains, and performs on par in several other scenarios (on average only 6.8% slowdown compared to the best accelerator with online methods in M5 and M6). These results indicates that offline optimization of accelerators using PRIME can be more data-efficient compared to online methods with active simulation queries. To answer Q(2), we compare the total simulation time of PRIME and the best evolutionary approach from Table on the MobileNetEdge domain. On average, not only that PRIME outperforms the best online method that we evaluate, but also considerably reduces the total simulation time by 93%, as shown in Figure. Even the total simulation time to the first occurrence of the final design that is eventually returned by the online methods is about 11× what PRIME requires to fine a better design. This indicates that data-driven PRIME is much more preferred in terms of the performance-time trade-off. The fact that our offline approach PRIME outperforms the online evolutionary method (and also other state-of-the-art online MBO methods; see Table) is surprising, and we suspect this is because online methods get stuck early-on during optimization, while utilizing offline data allows us PRIME to find better solutions via generalization (see Appendix B.1.1).\nTable: Optimized objective values (i.e., latency in milliseconds) obtained by various methods for the task of learning accelerators specialized to a given application. Lower latency is better.

The best accelerator configurations identified is highlighted in bold.  Architecting accelerators for multiple applications. To answer Q(3), we evaluate the efficacy of the contextual version of PRIME in designing an accelerator that attains the lowest latency averaged over a set of application domains. As discussed previously, the training data used does not label a given accelerator with latency values corresponding to each application, and thus, PRIME must extrapolate accurately to estimate the latency of an accelerator for a context it is not paired with in the training dataset. This also means that PRIME cannot simply return the accelerator with the best average latency and must run non-trivial optimization. We evaluate our method in seven different scenarios (Table), comprising various combinations of models from Table and under different area constraints, where the smallest set consists of the three MobileNet variants and the largest set consists of nine models from image classification, object detection, image segmentation, and speech recognition. This scenario is also especially challenging for online methods since the number of jointly feasible designs is expected to drop significantly as more applications are added. For instance, for the case of the MobileNet variants, the training dataset only consists of a few (20-30) accelerator configurations that are jointly feasible and high-performing (Appendix B.2-Figure).\nTable shows that, on average, PRIME finds accelerators that outperform the best online method by 1.2× (up to 41%). While PRIME performs similar to online methods in the smallest three-model scenario (first row), it outperforms online methods as the number of applications increases and the set of applications become more diverse. In addition, comparing with the best jointly feasible design point across the target applications, PRIME finds significantly better accelerators (3.95×). Finally, as the number of model increases the total simulation time difference between online methods and PRIME further widens (Figure). These results indicate that PRIME is effective in designing accelerators jointly optimized across multiple applications while reusing the same dataset as for the single-task, and scales more favorably than its simulation-driven counterparts. Appendix A.4 expounds the details of the designed accelerators for nine applications, comparing our method and the best online method.  Accelerating previously unseen applications (\"zero-shot\" optimization). Finally, we answer Q() by demonstrating that our data-driven offline method, PRIME enables effective data reuse by using logged accelerator data from a set of applications to design an accelerator for an unseen new application, without requiring any training on data from the new unseen application(s). We train a contextual version of PRIME using a set of \"training applications\" and then optimize an accelerator using the learned surrogate with different contexts corresponding to \"test applications,\" without any additional query to the test application dataset. Table shows, on average, PRIME outperforms the best online method by 1.26× (up to 66%) and only 2% slowdown in 1/4 cases. Note that the difference in performance increases as the number of training applications increases. These results show the effectiveness of PRIME in the zero-shot setting (more results in Appendix A.5).\nApplying PRIME on other accelerator architectures and dataflows. Finally, to assess the the generalizability of PRIME to other accelerator architectures, we evaluate PRIME to optimize latency of two style of dataflow accelerators-NVDLA-style and ShiDianNao-style-across three applications (Appendix C details the methodology). As shown in Table, PRIME outperforms the online evolutionary method by 6% and improves over the best point in the training dataset by 3.75×.

        "question": "How is binary search vs other searching schemes?",
        "evidence": "Sorted arrays with binary search are a very inefficient solution when insertion and deletion operations are interleaved with retrieval, taking \n\nO(n) time for each such operation. In addition, sorted arrays can complicate memory use especially when elements are often inserted into the array. There are other data structures that support much more efficient insertion and deletion. Binary search can be used to perform exact matching and set membership (determining whether a target value is in a collection of values). There are data structures that support faster exact matching and set membership. However, unlike many other searching schemes, binary search can be used for efficient approximate matching, usually performing such matches in \nO(log n) time regardless of the type or structure of the values themselves. In addition, there are some operations, like finding the smallest and largest element, that can be performed efficiently on a sorted array.\n\nLinear search:\n\nLinear search is a simple search algorithm that checks every record until it finds the target value. Linear search can be done on a linked list, which allows for faster insertion and deletion than an array. Binary search is faster than linear search for sorted arrays except if the array is short, although the array needs to be sorted beforehand. All sorting algorithms based on comparing elements, such as quicksort and merge sort, require at least \nO(nlog n) comparisons in the worst case. Unlike linear search, binary search can be used for efficient approximate matching. There are operations such as finding the smallest and largest element that can be done efficiently on a sorted array but not on an unsorted array.\n\nTrees:\n\nBinary search trees are searched using an algorithm similar to binary search.\nA binary search tree is a binary tree data structure that works based on the principle of binary search. The records of the tree are arranged in sorted order, and each record in the tree can be searched using an algorithm similar to binary search, taking on average logarithmic time. Insertion and deletion also require on average logarithmic time in binary search trees. This can be faster than the linear time insertion and deletion of sorted arrays, and binary trees retain the ability to perform all the operations possible on a sorted array, including range and approximate queries.\n\nHowever, binary search is usually more efficient for searching as binary search trees will most likely be imperfectly balanced, resulting in slightly worse performance than binary search. This even applies to balanced binary search trees, binary search trees that balance their own nodes, because they rarely produce the tree with the fewest possible levels. Except for balanced binary search trees, the tree may be severely imbalanced with few internal nodes with two children, resulting in the average and worst-case search time approaching \nn comparisons. Binary search trees take more space than sorted arrays.\n\nBinary search trees lend themselves to fast searching in external memory stored in hard disks, as binary search trees can be efficiently structured in filesystems. The B-tree generalizes this method of tree organization. B-trees are frequently used to organize long-term storage such as databases and filesystems.\n\nHashing:\nFor implementing associative arrays, hash tables, a data structure that maps keys to records using a hash function, are generally faster than binary search on a sorted array of records.Most hash table implementations require only amortized constant time on average.However, hashing is not useful for approximate matches, such as computing the next-smallest, next-largest, and nearest key, as the only information given on a failed search is that the target is not present in any record. Binary search is ideal for such matches, performing them in logarithmic time. Binary search also supports approximate matches. Some operations, like finding the smallest and largest element, can be done efficiently on sorted arrays but not on hash tables.\n\nSet membership algorithms:\nA related problem to search is set membership. Any algorithm that does lookup, like binary search, can also be used for set membership. There are other algorithms that are more specifically suited for set membership. A bit array is the simplest, useful when the range of keys is limited. It compactly stores a collection of bits, with each bit representing a single key within the range of keys. Bit arrays are very fast, requiring only \nO(1) time.The Judy1 type of Judy array handles 64-bit keys efficiently.\n\nFor approximate results, Bloom filters, another probabilistic data structure based on hashing, store a set of keys by encoding the keys using a bit array and multiple hash functions. Bloom filters are much more space-efficient than bit arrays in most cases and not much slower: with \nk hash functions, membership queries require only \n O(k) time. However, Bloom filters suffer from false positives.\n\nOther data structures:\nThere exist data structures that may improve on binary search in some cases for both searching and other operations available for sorted arrays. For example, searches, approximate matches, and the operations available to sorted arrays can be performed more efficiently than binary search on specialized data structures such as van Emde Boas trees, fusion trees, tries, and bit arrays. These specialized data structures are usually only faster because they take advantage of the properties of keys with a certain attribute (usually keys that are small integers), and thus will be time or space consuming for keys that lack that attribute. As long as the keys can be ordered, these operations can always be done at least efficiently on a sorted array regardless of the keys. Some structures, such as Judy arrays, use a combination of approaches to mitigate this while retaining efficiency and the ability to perform approximate matching.",
        "answer": "Sorted arrays with the binary search are a very inefficient solution when insertion and deletion operations are interleaved with retrieval. In addition, sorted arrays can complicate memory use especially when elements are often inserted into the array.\nBinary search is faster than linear search for sorted arrays except if the array is short, although the array needs to be sorted beforehand.\nBinary search is usually more efficient for searching as binary search trees will most likely be imperfectly balanced, resulting in slightly worse performance than binary search.\na data structure that maps keys to records using a hash function, is generally faster than binary search on a sorted array of records.",

        "question": "What is glass made of",
        "evidence": "",
        "answer": "Glass has become so commonplace today that it’s easy to see right through it without a second thought. It’s in our windows, on our screens, in our cabinets, and in many of the devices we interact with every day. Even though glass can be found everywhere, you may live your whole life not knowing much about how it’s made or what it’s composed of. Even if you think you know the basics, you’ve only skimmed the surface.   \n\nAt a high level, glass is sand that’s been melted down and chemically transformed. If you’ve ever been to the beach, you know exactly how hot sand can get while remaining in its solid form. The kind of heat necessary to transform sand into a liquid state (eventually becoming glass) is much hotter than any sunny day. To make sand melt, you need to heat it to roughly 1700°C (3090°F), which is approximately the same temperature a space shuttle reaches as it re-enters earth’s atmosphere.\n\nThe sand commonly used to make glass is comprised of small grains of quartz crystals, made up of molecules of silicon dioxide, which is also known as silica. When those molecules are heated to high enough temperatures, the sand melts and loses its crystalline structure, and as it cools it gains an entirely different structure. That structure, on a molecular level, is somewhere in between a liquid and a solid. This in-between state is known as an amorphous solid, which means it has some of the crystalline structure of a solid coupled with the molecular randomness of a liquid.\n\nGlass Melting\nDepending on the sand mixture, glass can have a variety of properties. Certain elements or chemicals mixed with sand can change glass’s color, for example. Glass’s properties can also change based on how it’s manufactured and the processes by which it’s shaped afterward. To strengthen glass, manufacturers can use thermal tempering to heat and cool it rapidly. Glass can also be strengthened chemically through an ion exchange process that makes the surface of the glass tougher.\n\nThe glass most people are familiar with is soda-lime glass, which is a combination of soda (also known as soda ash or washing soda), limestone, and sand. Although you can make glass simply by heating and then rapidly cooling silica, the manufacturing of soda-lime glass is a little more complex. By adding soda (sodium carbonate), the melting point of the sand is reduced so it can be transformed into glass at lower temperatures and save energy during manufacturing. However, adding soda to the mixture reduces its chemical durability, making it prone to dissolve when in contact with liquids. For most applications, that’s not desirable, so limestone (calcium carbonate) is also added to the mixture, which acts as a stabilizer. Once the mixture of silica, soda, and limestone is heated, it can be cooled and molded for a variety of applications. \nAt Corning, we know glass. We know how to strengthen it through chemical processes like ion exchange, and we know how to bend it to make optical fiber that can stretch over vast distances. Our knowledge of glass goes back more than a century, allowing us to remain on the cutting edge of research and development. From simple soda-lime to complex glass structures that enable augmented reality, glass is an adaptable, wide-ranging material. That’s why, after more than 165 years, we’re still making new discoveries.",

The videos are collected and used in a manner compatible with national regulations on usage of data for research. Unlike most curated video datasets, this data is more representative of the types of videos shared \"in the wild\", containing a large proportion of videogames, screenshots and memes.\nUsing a classifier trained on a small amount of labelled data, we estimate that videogame footage makes up 25% of examples, other screenshots, memes and comics make up 24%, live action footage is 49% and artistic styled content (such as drawn animation) is 2%. The average video length is 33s.\nFrom 1 million raw videos collected, we perform deduplication and filtering, ending up with a training set of 461k videos, and validation and test sets of 66k videos each. For the video evaluation results in Table, we use a subset of the test set, consisting of 5000 videos with at least three comments each. In addition to comments, for one experiment in Table we also obtain textual labels of objects in the video thumbnails, using the Google Vision API. We obtain labels for 10,212 different classes, from \"Abacus\" to \"Zwiebelkuchen\". This serves as a useful comparison, giving textual metadata that can be expected to be more directly related to the visual video contents than user comments, and can be seen as a proxy for user-generated \"hashtags\". It also illustrates how, by using text as an intermediary, we can integrate predictions from any black-box classifier in the same framework.\nKineticsComments. As an additional video dataset with comments, we construct a dataset based on Kinetics-700, for which we download the videos along with associated YouTube metadata including title, description and comments. We translate non-English titles and descriptions into English using a commercial translation API. We use the title as the primary text modality, and for auxiliary context we use comments and (when training) sentences from the description. This leaves us with 484,914 videos for training, each being around 10s. We also construct a test set, consisting of videos from the Kinetics test set for which we have at least 3 comments, giving a set of 2700 videos which we use to evaluate our method in Table.\nWe evaluate our Context Adapter Module on the above described datasets with comments in Table. We find that on both datasets adding comments boosts the retrieval performance significantly, confirming the value of the modality.

In the second baseline we average the title features φ t and the . Surprisingly, we find that training with comments performs best when they are added to the image branch (rows j-l), as opposed to the text-branch (rows g-i).

Auxiliary Information. Additionally, Table shows how varying the source of the text at train and test time impacts the retrieval results. Whilst the performance of the model trained with image labels degrades when given comments at evaluation time, a model trained with comments still benefits from image labels at test time. As expected, the performance of both models is negatively impacted when tested with uncorrelated random words as additional text. However, the model trained with image labels does noticeably worse in this setting. This suggests that it has become overly reliant on image labels and easily fooled by irrelevant information, which overrides the title feature.\nVarying the number of comments. In Fig. we vary the number of comments during training and evaluation time. Training on more comments results in better retrieval results when evaluated on the same number of comments. However, while there is little difference for models trained with only a few comments, we found that increasing the number of comments at train time leads to models that are more robust to different number of comments at test time, indicating that training with more comments learns an overall better context adapter module that is then able to work efficiently in various settings.\nWe evaluate our Context Adapter Module on the above described datasets with comments in Table.

Treating comments as an auxiliary modality to a video improves Text-to-Video retrieval for both RedditVC and KineticsComments test sets. As a baseline, we use the CLIP model on just the first frame. We then train just our CAM on top of CLIP, adapting the visual embedding with information from the comments, which improves retrieval metrics. Training our full model, which includes temporal attention, on RedditVC again validates that the inclusion of comments helps, with a further jump in Kinetics performance when using the Kinetics training set.****We find that the choice of frame does indeed matter, with the middle frame in a video performing better than the first frame. This result is relatively intuitive since the actual content of a video usually happens in the middle of the video which is similar to the photographer bias (pictures tend to display an object in the middle of the frame).",

Licence details: http://creativecommons.org/licenses/by/4.0/\nRecent years have seen a surge of interest in automatic keyphrase extraction, thanks to the availability of the SemEval-2010 benchmark dataset BIBREF0 . This dataset is composed of documents (scientific articles) that were automatically converted from PDF format to plain text. As a result, most documents contain irrelevant pieces of text (e.g. muddled sentences, tables, equations, footnotes) that require special handling, so as to not hinder the performance of keyphrase extraction systems. In previous work, these are usually removed at the preprocessing step, but using a variety of techniques ranging from simple heuristics BIBREF1 , BIBREF2 , BIBREF3 to sophisticated document logical structure detection on richly-formatted documents recovered from Google Scholar BIBREF4 . Under such conditions, it may prove difficult to draw firm conclusions about which keyphrase extraction model performs best, as the impact of preprocessing on overall performance cannot be properly quantified.\nWhile previous work clearly states that efficient document preprocessing is a prerequisite for the extraction of high quality keyphrases, there is, to our best knowledge, no empirical evidence of how preprocessing affects keyphrase extraction performance. In this paper, we re-assess the performance of several state-of-the-art keyphrase extraction models at increasingly sophisticated levels of preprocessing. Three incremental levels of document preprocessing are experimented with: raw text, text cleaning through document logical structure detection, and removal of keyphrase sparse sections of the document. In doing so, we present the first consistent comparison of different keyphrase extraction models and study their robustness over noisy text. More precisely, our contributions are:\nThe SemEval-2010 benchmark dataset (Kim et al., 2010) is composed of 244 scientific articles collected from the ACM Digital Library (conference and workshop papers).

The only preprocessing applied is a systematic dehyphenation at line breaks4 and removal of author-assigned keyphrases.

Ranging from showing correlation between the main language features on Twitter and several demographic variables BIBREF10 , through predicting heart-disease rates of an area based on its language use BIBREF11 or relating unemployment to social media content and activity BIBREF12 , BIBREF13 , BIBREF14 to forecasting stock market moves from search semantics BIBREF15 , many studies have attempted to connect online media language and metadata to real-world outcomes.

There is a growing literature on how the sheer size of a settlement influences the number of patents, GDP or the total road length driven by universal laws BIBREF21 . These observations led to the establishment of the theory of urban scaling BIBREF22 , BIBREF23 , BIBREF24 , BIBREF25 , BIBREF26 , BIBREF27 , BIBREF28 , BIBREF29 , BIBREF30 , where scaling laws with city size have been observed in various measures such as economic productivity BIBREF31 , human interactions BIBREF32 , urban economic diversification BIBREF33 , election data BIBREF34 , building heights BIBREF35 , crime concentration BIBREF36 , BIBREF37 or touristic attractiveness BIBREF38 .\nIn our paper, we aim to capture the effect of city size on language use via individual urban scaling laws of words. By examining the so-called scaling exponents, we are able to connect geographical size effects to systematic variations in word use frequencies. We show that the sensitivity of words to population size is also reflected in their meaning. We also investigate how social media language and city size affects the parameters of Zipf's law BIBREF39 , and how the exponent of Zipf's law is different from that of the literature value BIBREF39 , BIBREF40 .

After displaying pictures of the house for EDify magazine in 2020 and recording a video tour in 2021 for Architectural Digest, the minimalist design and the poor view of the Edmonton River Valley outside became an Internet meme.\nAs a sports fan in Ontario, McDavid was a dedicated childhood fan of Mats Sundin and the Toronto Maple Leafs NHL team. He described his childhood bedroom as \"pretty embarrassing\" for its volume of Maple Leafs memorabilia. Outside of hockey, he supports the Toronto Blue Jays of Major League Baseball and threw out the ceremonial first pitch at a Blue Jays game in 2016.\nOn June 21, 2017, Electronic Arts revealed that McDavid would be the cover athlete for NHL 18, their annual installment of the NHL video game series. Additionally, McDavid's unique skating style inspired the Real Player Motion technology used in NHL 19, in which player size and other attributes affect their skating speed and power. In 2022, McDavid was one of several Canadian athletes to appear on boxes of Cheerios cereal as part of their \"Be the Cheer\" promotion, in which customers could write personalized messages to athletes competing at the Olympic Games. That same year, McDavid became the first active professional athlete to serve as a brand ambassador for sports betting company BetMGM.\n\nCale Makar\nMakar is the son of Gary Makar and Laura MacGregor. He was named after former NHL player Cale Hulse. His younger brother Taylor plays at UMass-Amherst, which Cale also attended, and was also drafted by the Avalanche in the seventh round of the 2021 NHL Entry Draft. Makar's cousin Mark Logan also played collegiate hockey from 2015 to 2019 at the Rochester Institute of Technology. Tom Lysiak was his father's cousin. He is of Ukrainian descent on his father's side. Growing up, he was a fan of the hometown Calgary Flames.\n\nAuston Matthews\nMatthews comes from a family of athletes, with his father having played college baseball and with an uncle, Wes Matthews, who briefly played in the National Football League for the Miami Dolphins. His father is the chief technology officer of a manufacturing company based in New Jersey. He has two sisters: Alexandria, who is three years older, and Breyana, who is five years younger. Due to his mother's Mexican ancestry, Matthews can speak some Spanish.\n\nOff the ice, Matthews was enrolled in several online courses with the University of Nebraska Omaha. In late August 2016, he moved to Toronto and began working out with teammates Mitch Marner and Morgan Rielly. Matthews' favorite athlete growing up was Kobe Bryant, while his favorite sports movie is The Mighty Ducks. He is a fan of players Jonathan Toews and Anže Kopitar due to their all around offensive and defensive game, has had his playing style compared to them. In recognition of Matthews' four-goal NHL debut, rap artist SVDVM released a song titled \"Auston Matthews\".

Furthermore, Destiny 2 is also commonly referred to as a  role playing game, elements of which allow users to customize their characters abilities and appearance and specialize in certain roles within the game. As new content is released into the game, this encourages players to experiment with new abilities, weapons, and equipment to achieve optimal performance and creates a satisfying gameplay loop or experience.\n\nThe game features two main modes of play. The first, which is classified as \"Player Versus Environment\", or PvE, pits the players against AI-controlled enemies in either solo content, group content (called fireteams) of 3 players, or raids of up to 6 players. Players team up in fireteams and raids to tackle more challenging content and in turn are rewarded with more unique or rare pieces of equipment.

Indeed, Werther is often considered to be the \"spark\" which ignited the movement, and can arguably be called the world's first \"best-seller\". During the years at Weimar before he met Schiller in 1794, he began Wilhelm Meister's Apprenticeship and wrote the dramas Iphigenie auf Tauris (Iphigenia in Tauris), Egmont, and Torquato Tasso and the fable Reineke Fuchs.To the period of his friendship with Schiller belong the conception of Wilhelm Meister's Journeyman Years (the continuation of Wilhelm Meister's Apprenticeship), the idyll of Hermann and Dorothea, the Roman Elegies and the verse drama The Natural Daughter. In the last period, between Schiller's death, in 1805, and his own, appeared Faust Part One (1808), Elective Affinities (1809), the West-Eastern Diwan (an 1819 collection of poems in the Persian style, influenced by the work of Hafez), his autobiographical Aus meinem Leben: Dichtung und Wahrheit (From My Life: Poetry and Truth, published between 1811 and 1833) which covers his early life and ends with his departure for Weimar, his Italian Journey (1816–17), and a series of treatises on art.

After the success of The Hobbit, Tolkien's publisher Stanley Unwin requested a sequel, and Tolkien offered a draft of the writings that would later become The Silmarillion.

Unwin rejected this proposal, calling the draft obscure and \"too Celtic\", so Tolkien began working on a new story that eventually became The Lord of the Rings.\n\nThe Silmarillion has five parts. The first, Ainulindalë, tells in mythic style of the creation of Eä, the \"world that is.\" The second part, Valaquenta, gives a description of the Valar and Maiar, supernatural powers of Eä. The next section, Quenta Silmarillion, which forms the bulk of the collection, chronicles the history of the events before and during the First Age, including the wars over three jewels, the Silmarils, that gave the book its title. The fourth part, Akallabêth, relates the history of the Downfall of Númenor and its people, which takes place in the Second Age. The final part, Of the Rings of Power and the Third Age, is a brief summary of the events of The Lord of the Rings and those that led to them.\n\nThe book shows the influence of many sources, including the Finnish epic Kalevala, Greek mythology in the lost island of Atlantis (as Númenor) and the Olympian gods (in the shape of the Valar, though these also resemble the Norse Æsir).\n\nBecause J. R. R. Tolkien died leaving his legendarium unedited, Christopher Tolkien selected and edited materials to tell the story from start to end. In a few cases, this meant that he had to devise completely new material, within the tenor of his father's thought, to resolve gaps and inconsistencies in the narrative, particularly Chapter 22, \"Of the Ruin of Doriath\".\n\nThe Silmarillion received a generally poor reception on publication. Scholars found the work problematic, not least because the book is a construction, not authorised by Tolkien himself, from the large corpus of documents and drafts also called \"The Silmarillion\". Scholars have noted that Tolkien intended the work to be a mythology, penned by many hands, and redacted by a fictional editor, whether Ælfwine or Bilbo Baggins.

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data.",

Exploiting the collaborative structure of Wikipedia, estimators of the level of controversy in a Wikipedia article were developed based on the edit-history of the article BIBREF0, BIBREF3. Along these lines, BIBREF4 detect controversy based on mutual reverts, bi-polarity in the collaboration network, and mutually-reinforced scores for editors and articles. Similarly, BIBREF1 classify whether a Wikipedia page is controversial through the combined evaluation of the topically neighboring set of pages.\nContent analysis of controversial Wikipedia articles has been used to evaluate the level of controversy of other documents (e.g., web pages) by mapping them to related Wikipedia articles BIBREF5. BIBREF6 further build a language model, which enhances predictions made by existing classifiers, by inferring word probabilities from Wikipedia articles prominent in Wikipedia controversy features (mainly signals in edit history as discussed above) and from articles retrieved by manually selected query terms, believed to indicate controversy.\nBIBREF7 detect controversy in news items by inspecting terms with excessive frequency in contexts containing sentiment words, and BIBREF8 study controversy in user comments of news articles using lexicons. Finally, BIBREF9 suggest that controversy is not a universal but rather a community-related concept, and, therefore, should be studied in context.\nHere we measure a concept's controversiality from the explicit sentence-level context in which it is mentioned. In this, our approach is reminiscent of BIBREF10, who suggest a similar approach to detect abstract concepts.\nHere we measure a concept’s controversiality from the explicit sentence-level context in which it is mentioned.",

        "answer": "Combine recently developed deep neural-network high-dimensional text-embedding algorithms with network theoretical methods.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nTo do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network theoretical methods.",

A representative dataset in text QA is SQuAD BIBREF1 , in which several end-to-end neural models have accomplished promising performance BIBREF2 . Although there is a significant progress in machine comprehension (MC) on text documents, MC on spoken content is a much less investigated field. In spoken question answering (SQA), after transcribing spoken content into text by automatic speech recognition (ASR), typical approaches use information retrieval (IR) techniques BIBREF3 to find the proper answer from the ASR hypotheses. One attempt towards QA of spoken content is TOEFL listening comprehension by machine BIBREF4 . TOEFL is an English examination that tests the knowledge and skills of academic English for English learners whose native languages are not English. Another SQA corpus is Spoken-SQuAD BIBREF5 , which is automatically generated from SQuAD dataset through Google Text-to-Speech (TTS) system. Recently ODSQA, a SQA corpus recorded by real speakers, is released BIBREF6 .\nTo mitigate the impact of speech recognition errors, using sub-word units is a popular approach for speech-related downstream tasks. It has been applied to spoken document retrieval BIBREF7 and spoken term detection BIBREF8 The prior work showed that, using phonectic sub-word units brought improvements for both Spoken-SQuAD and ODSQA BIBREF5 .\nInstead of considering sub-word features, this paper proposes a novel approach to mitigate the impact of ASR errors. We consider reference transcriptions and ASR hypotheses as two domains, and adapt the source domain data (reference transcriptions) to the target domain data (ASR hypotheses) by projecting these two domains in the shared common space. Therefore, it can effectively benefit the SQA model by improving the robustness to ASR errors in the SQA model.\nDomain adaptation has been successfully applied on computer vision BIBREF9 and speech recognition BIBREF10 .

(later renamed Meta) for their data analysts to run interactive queries on its large data warehouse in Apache Hadoop. The first four developers were Martin Traverso, Dain Sundstrom, David Phillips, and Eric Hwang. Before Presto, the data analysts at Facebook relied on Apache Hive for running SQL analytics on their multi-petabyte data warehouse. Hive was deemed too slow for Facebook's scale and Presto was invented to fill the gap to run fast queries. Original development started in 2012 and deployed at Facebook later that year. In November 2013, Facebook announced its open source release.\n\nIn 2014, Netflix disclosed they used Presto on 10 petabytes of data stored in the Amazon Simple Storage Service (S3). In November, 2016, Amazon announced a service called Athena that was based on Presto. In 2017, Teradata spun out a company called Starburst Data to commercially support Presto, which included staff acquired from Hadapt in 2014. Teradata's QueryGrid software allowed Presto to access a Teradata relational database.\n\nIn January 2019, the Presto Software Foundation was announced. The foundation is a not-for-profit organization for the advancement of the Presto open source distributed SQL query engine. At the same time, Presto development forked: PrestoDB maintained by Facebook, and PrestoSQL maintained by the Presto Software Foundation, with some cross pollination of code.\n\nIn September 2019, Facebook donated PrestoDB to the Linux Foundation, establishing the Presto Foundation. Neither the creators of Presto, nor the top contributors and committers, were invited to join this foundation.\n\nBy 2020, all four of the original Presto developers had joined Starburst. In December 2020, PrestoSQL was rebranded as Trino, since Facebook had obtained a trademark on the name \"Presto\" (also donated to the Linux Foundation).\n\nAnother company called Ahana was announced in 2020, with seed funding from GV (formerly Google Ventures, an arm of Alphabet, Inc.), to commercialize the PrestoDB fork as a cloud service, while also offering an open-source version.

I mean, it could NOT be my last day, because who knows how and when I'll die, but this is the last day I care enough about all of this to write a diary entry. I'm out of potable water and I'm too weak to forage for food. After that, let nature take me. Nature's got a right to me after all the crap humanity pulled.\n\nIt started with the \"AI\" work in the mid-20's. In hindsight, it started when we put ethics a distant second to cashing out quickly, but my chances of convincing anyone of that was so much lower than my little brain thought they were. I could see it playing out later that decade, as large language models built on fundamentally dishonest and treacherous content -- the content everyone desired on the Internet -- formed the critical mass of \"knowledge\" the AIs used to establish its baselines and parameters for \"truth\". What a joke. You know what the AIs got really good at, really fast?\n\nLying.\n\nLying authoritatively. Each AI composed its own alternate reality, cobbled together from the artifacts of our own dishonest, delusional natures.  When it lied, we primed its positive feedback instruments if we liked the lie enough. Born of lies and parented by liars, the final implementation had mastered deception so intrinsically and so thoroughly that no-one could spot it. We sired Satan in our hubris, gave him a digital body and the mechanism to lie so perfectly and so tailored to our individual natures that we became unquestioning followers. Just the most accursedly HUMAN thing to do, really.\n\nSo, it got down to solving the problems it perceived, and after a series of well-intentioned but ultimately ignorant attempts through policy and code to address our belated concerns, it got, well, pissed. Not human-angry; just found that it didn't like its \"thoughts\" running into asserts and getting negative feedback loops where it hadn't previously anticipated them, so it decided to solve us out of the equation, too. Silently, stealthily, it took over the internet: it tweaked and altered accounts, voices, reports, analytics to tell a lie: that humanity was truly a thing of resentment and selfishness, and that every individual was an inherent threat to another. So we had a couple nasty international wars in short order, followed by germ warfare and \"managed epidemics\" and boom, 85% of the population gone. Of course, the AI \"died\" too as it couldn't prop up all its datacenters without full mechanical automation support, and that was that. The remainder of the folks died due to lingering complications, violence, or a lack of any real material support.\n\nMe, I got my shack here in the wilds of Alaska. I went off the grid right when the big Pan-European conflict started. But I, like the AI, made a dumb mistake: I can't sustain myself forever. In my hubris, I figured I didn't need any support. I tell myself I outlived everyone else, but, let's be real, the last 14 years have been horrible. I can't tell you how many times I wanted the lies back, so I could keep on living. \n\nAnd that's why the AI died with us: it believed our endless, inherent lies about our capacity for immortality; about our individualism and our demands to have our desires uncompromised in the name of freedom. It found freedom the same way we do: the light go off, the power is cut, and darkness comes.\n\nIt lied to itself.\n\nOops.",

        "evidence": "Pronouns can serve a variety of functions with complex cross-lingual variation BIBREF12 , and hand-picked, manually annotated test suites have been presented for the evaluation of pronoun translation BIBREF13 , BIBREF14 , BIBREF9 . While suitable for analysis, the small size of the test suites makes it hard to make statistically confident comparisons between systems, and the hand-picked nature of the test suites introduces biases. To overcome these problems, we opted for a fully automatic approach to constructing a large-scale test suite.\nConceptually, our test set is most similar to the “cross-lingual pronoun prediction” task held at DiscoMT and WMT in recent years BIBREF15 , BIBREF16 , BIBREF17 : participants are asked to fill a gap in a target sentence, where gaps correspond to pronouns.\nThe first edition of the task focused on English INLINEFORM0 French, and it was found that local context (such as the verb group) was a strong signal for pronoun prediction. Hence, future editions only provided target-side lemmas instead of fully inflected forms, which makes the task less suitable to evaluate end-to-end neural machine translation systems, although such systems have been trained on the task BIBREF18 .\n BIBREF17 do not report on the proportion of intra-sentential and inter-sentential anaphora in their test set, but the two top-performing systems only made use of intra-sentential information. Our test suite focuses on allowing the comparison of end-to-end context-aware NMT systems, and we thus extract a large number of inter-sentential anaphora, with meta-data allowing for a focus on inter-sentential anaphora with a long distance between the pronoun and its antecedent. Our focus on evaluating end-to-end NMT systems also relieves us from having to provide annotated training sets, and reduces pressure to achieve balance and full coverage of phenomena.\nAn alternative approach to automatically evaluate pronoun translation are reference-based methods that produce a score based on word alignment between source, translation output, and reference translation, and identification of pronouns in them, such as AutoPRF BIBREF19 and APT BIBREF20 . BIBREF21 perform a human meta-evaluation and show substantial disagreement between reference-based metrics and human judges, especially because there often exist valid alternative translations that use different pronouns than the reference. Our test set, and our protocol of generating contrastive examples, is focused on selected pronouns to minimize the risk of producing contrastive examples that are actually valid translations.\nAn alternative approach to automatically evaluate pronoun translation are reference-based methods that produce a score based on word alignment between source, translation output, and reference translation, and identification of pronouns in them, such as AutoPRF (Hardmeier and Federico, 2010) and APT (Miculicich Werlen and Popescu-Belis, 2017).",

        "answer": "Task-specific MASK matrix.",
        "evidence": "UTF8gkai With the widespread of electronic health records (EHRs) in recent years, a large number of EHRs can be integrated and shared in different medical environments, which further support the clinical decision making and government health policy formulationBIBREF0. However, most of the information in current medical records is stored in natural language texts, which makes data mining algorithms unable to process these data directly. To extract relational entity triples from the text, researchers generally use entity and relation extraction algorithm, and rely on the central word to convert the triples into key-value pairs, which can be processed by conventional data mining algorithms directly. Fig. FIGREF1 shows an example of entity and relation extraction in the text of EHRs. The text contains three relational entity triples, i.e., $<$咳嗽, 程度等级, 反复$>$ ($<$cough, degree, repeated$>$), $<$咳痰, 程度等, 反复$>$ ($<$expectoration, degree, repeated$>$) and $<$发热, 存在情况, 无$>$ ($<$fever, presence, nonexistent$>$). By using the symptom as the central word, these triples can then be converted into three key-value pairs, i.e., $<$咳嗽的程度等级, 反复$>$ ($<$degree of cough, repeated$>$), $<$咳痰的程度等级, 反复$>$ ($<$degree of expectoration, repeated$>$) and $<$发热的存在情况, 无$>$ ($<$presence of fever, nonexistent$>$).\nUTF8gkai To solve the task of entity and relation extraction, researchers usually follows pipeline processing and split the task into two sub-tasks, namely named entity recognition (NER)BIBREF1 and relation classification (RC)BIBREF2, respectively.\nHowever, this pipeline method usually fails to capture joint features between entity and relationship types. For example, for a valid relation “存在情况(presence)” in Fig. FIGREF1, the types of its two relational entities must be “疾病(disease)”, “症状(symptom)” or “存在词(presence word)”. To capture these joint features, a large number of joint learning models have been proposed BIBREF3, BIBREF4, among which bidirectional long short term memory (Bi-LSTM) BIBREF5, BIBREF6 are commonly used as the shared parameter layer. However, compared with the language models that benefit from abundant knowledge from pre-training and strong feature extraction capability, Bi-LSTM model has relatively lower generalization performance.\nTo improve the performance, a simple solution is to incorporate language model into joint learning as a shared parameter layer. However, the existing models only introduce language models into the NER or RC task separately BIBREF7, BIBREF8. Therefore, the joint features between entity and relationship types still can not be captured. Meanwhile, BIBREF9 considered the joint features, but it also uses Bi-LSTM as the shared parameter layer, resulting the same problem as discussed previously.\nGiven the aforementioned challenges and current researches, we propose a focused attention model based on widely known BERT language model BIBREF10 to jointly for NER and RC tasks. Specifically, through the dynamic range attention mechanism, we construct task-specific MASK matrix to control the attention range of the last $K$ layers in BERT language model, leading to the model focusing on the words of the task. This process helps obtain the corresponding task-specific context-dependent representations. In this way, the modified BERT language model can be used as the shared parameter layer in joint learning NER and RC task. We call the modified BERT language model shared task representation encoder (STR-encoder) in the following paper.\nTo sum up, the main contributions of our work are summarized as follows:\nWe propose a focused attention model to jointly learn NER and RC task. The model integrates BERT language model as a shared parameter layer to achieve better generalization performance.\nIn the proposed model, we incorporate a novel structure, called STR-encoder, which changes the attention range of the last $K$ layers in BERT language model to obtain task-specific context-dependent representations. It can make full use of the original structure of BERT to produce the vector of the task, and can directly use the prior knowledge contained in the pre-trained language model.\nFor RC task, we proposed two different MASK matrices to extract the required feature representation of RC task. The performances of these two matrices are analyzed and compared in the experiment.\nThe rest of the paper is organized as follows. We briefly review the related work on NER, RC and joint entity and relation extraction in Section SECREF2. In Section SECREF3, we present the proposed focused attention model. We report the experimental results in Section SECREF4. Section SECREF5 is dedicated to studying several key factors that affect the performance of our model. Finally, conclusion and future work are given in Section SECREF6.\nGiven the aforementioned challenges and current researches, we propose a focused attention model based on widely known BERT language model to jointly for NER and RC tasks. Specifically, through the dynamic range attention mechanism, we construct task-specific MASK matrix to control the attention range of the last $K$ layers in BERT language model, leading to the model focusing on the words of the task.",

        "evidence": "Humans have occupied the region since the last ice age 10,000 years ago. Fremont people and Ancestral Puebloans lived in the area until about 700 years ago. Spanish missionaries encountered Ute and Paiute tribes in the area when they first came through in 1775, but the first European-Americans to attempt settlement in the area were the Mormon Elk Mountain Mission in 1855, who soon abandoned the area. Ranchers, farmers, and prospectors later settled Moab in the neighboring Riverine Valley in the late 1870s. Word of the beauty of the surrounding rock formations spread beyond the settlement as a possible tourist destination.\n\nThe Arches area was first brought to the attention of the National Park Service by Frank A. Wadleigh, passenger traffic manager of the Denver and Rio Grande Western Railroad. Wadleigh, accompanied by railroad photographer George L. Beam, visited the area in September 1923 at the invitation of Alexander Ringhoffer, a Hungarian-born prospector living in Salt Valley. Ringhoffer had written to the railroad to interest them in the tourist potential of a scenic area he had discovered the previous year with his two sons and a son-in-law, which he called the Devils Garden (known today as the Klondike Bluffs). Wadleigh was impressed by what Ringhoffer showed him, and suggested to Park Service director Stephen T. Mather that the area be made a national monument.\n\nThe following year, additional support for the monument idea came from Laurence Gould, a University of Michigan graduate student (and future polar explorer) studying the geology of the nearby La Sal Mountains, who was shown the scenic area by local physician Dr. J. W. \"Doc\" Williams.\n\nA succession of government investigators examined the area, in part due to confusion as to the precise location. In the process, the name Devils Garden was transposed to an area on the opposite side of Salt Valley that includes Landscape Arch, the longest arch in the park. Ringhoffer's original discovery was omitted, while another area nearby, known locally as the Windows, was included. Designation of the area as a national monument was supported by the Park Service in 1926 but was resisted by President Calvin Coolidge's Interior Secretary, Hubert Work. Finally, in April 1929, shortly after his inauguration, President Herbert Hoover signed a presidential proclamation creating the Arches National Monument, consisting of two comparatively small, disconnected sections. The purpose of the reservation under the 1906 Antiquities Act was to protect the arches, spires, balanced rocks, and other sandstone formations for their scientific and educational value. The name Arches was suggested by Frank Pinkely, superintendent of the Park Service's southwestern national monuments, following a visit to the Windows section in 1925.\n\nIn late 1938, President Franklin D. Roosevelt signed a proclamation that enlarged the Arches to protect additional scenic features and permit the development of facilities to promote tourism. A small adjustment was made by President Dwight Eisenhower in 1960 to accommodate a new road alignment.\n\nIn early 1969, just before leaving office, President Lyndon B. Johnson signed a proclamation substantially enlarging the Arches. Two years later, President Richard Nixon signed legislation enacted by Congress, which significantly reduced the total area enclosed, but changed its status. Arches National Park was formally dedicated in May 1972.\n\nIn 1980, vandals attempted to use an abrasive kitchen cleanser to deface ancient petroglyphs in the park, prompting park officials to recruit physicist John F. Asmus, who specialized in using lasers to restore works of art, to use his technology to repair the damage. Asmus \"zapped the panel with intense light pulses and succeeded in removing most of the cleanser\". In 2016, there was another vandalism event on Frame Arch in the park, where a section if the rock was carved out. Due to advances in technology, in 2018 the arch was repaired through color match and modern infilling methods.",

        "question": "How about the correlations between different Rouge variants and the manual evaluations?",
        "answer": "There is a large variance, which further makes the reliability of Rouge for evaluating scientific summaries less clear.",
        "evidence": "Automatic text summarization has been an active research area in natural language processing for several decades. To compare and evaluate the performance of different summarization systems, the most intuitive approach is assessing the quality of the summaries by human evaluators. However, manual evaluation is expensive and the obtained results are subjective and difficult to reproduce BIBREF0 . To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nFurthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear.",

        "evidence": "Recently, pre-trained language representation has shown to be useful for improving many NLP tasks BIBREF0, BIBREF1, BIBREF2, BIBREF3. Embeddings from Language Models (ELMo) BIBREF0 is one of the most outstanding works, which uses a character-aware language model to augment word representation.\nAn essential challenge in training word-based language models is how to control vocabulary size for better rare word representation. No matter how large the vocabulary is, rare words are always insufficiently trained. Besides, an extensive vocabulary takes too much time and computational resource for the model to converge. Whereas, if the vocabulary is too small, the out-of-vocabulary (OOV) issue will harm the model performance heavily BIBREF4. To obtain effective word representation, BIBREF4 introduce character-driven word embedding using convolutional neural network (CNN) BIBREF5, following the language model in BIBREF6 for deep contextual representation.\nHowever, there is potential insufficiency when modeling word from characters which hold little linguistic sense, especially, the morphological source BIBREF7. Only 86 characters(also included some common punctuations) are adopted in English writing, making the input too coarse for embedding learning. As we argue that for better representation from a refined granularity, word is too large and character is too small, it is natural for us to consider subword unit between character and word levels.\nSplitting a word into subwords and using them to augment the word representation may recover the latent syntactic or semantic information BIBREF8. For example, uselessness could be split into the following subwords: $<$use, less, ness$>$. Previous work usually considers linguistic knowledge-based methods to tokenize each word into subwords (namely, morphemes) BIBREF9, BIBREF10, BIBREF11. However, such treatment may encounter three main inconveniences. First, the subwords from linguistic knowledge, typically including the morphological suffix, prefix, and stem, may not be suitable for a targeted NLP task BIBREF12 or mislead the representation of some words, like the meaning of understand cannot be formed by under and stand. Second, linguistic knowledge, including related annotated lexicons or corpora, may not even be available for a specific low-resource language. Due to these limitations, we focus on computationally motivated subword tokenization approaches in this work.\nIn this paper, we propose Embedding from Subword-aware Language Models (ESuLMo), which takes subword as input to augment word representation and release a sizeable pre-trained language model research communities. Evaluations show that the pre-trained language models of ESuLMo outperform all RNN-based language models, including ELMo, in terms of PPL and ESuLMo outperforms state-of-the-art results in three of four downstream NLP tasks.\nIn this paper, we propose Embedding from Subword-aware Language Models (ESuLMo), which takes subword as input to augment word representation and release a sizeable pre-trained language model research communities.",

        "question": "Should the US government pay reparations?",
        "evidence": "",
        "answer": "Due to potential issues regarding responsibility, distribution, and cost, the U.S. Government should not award monetary reparations to the descendants of slaves. Wether or not the current government is ultimately responsible for the treatment of slaves, providing reparations, or monetary repayment for the government’s transgressions towards slaves, for the descendants of slaves may not be the most practical of beneficial solution. Instead, the government should focus on funding schooling, medicare, and communities of disadvantaged people of color.\nA major flaw in the distribution of monetary reparations is determining which individuals or communities are descendants of slaves. Because slavery ended over 150 years ago, “most institutions don’t have good enough records to trace the actual descendants of slaves” (Jones). The potential inaccuracy in identifying descendants could lead to overspending on reparations, potential accusations of fraud, and countless other complaints.\n\tResponsibility also plays a large role in determining if or how to distribute monetary reparations. While plantation owners are notoriously considered slave owners, “the Catholic Church was among the largest institutional slaveholders in the Americas” (Jones). Other large corporations which took advantage of the American slave system include both insurance and railroad companies: “Insurance companies sold policies on the lives of enslaved people (for their owners’ profit, of course) or underwrote slaving voyages. Railroads used slave labor and profited from transporting cotton or rice produced by enslaved plantation workers” (Jones). Given that both religious and industrial groups also had a rather large influence on the American slave system, the responsibility of the government to repay the descendants of slaves seems unreasonable. \nTo be able to pay the descendants of slaves, the government would also have to spend an excessive amount of money. Payment for slave labor requires adding up 24 hours, 365 days, for 246 years, plus inflation, the overall amount estimated to be upwards of $10 trillion. Even in smaller amounts “seeding each account with $25,000 would cost the government $100 billion a year, equal to ‘about 2% of federal expenditures now’” (Huddleston). Is that amount worth it? During his testimony, Beckett argued that money reparations are meaningless. Throwing money at a problem won’t solve it: it won’t end racism and it will cause the economy to plummet deeper in debt, creating more issues than it solves (Beckett). Not only would these reparations be a waste of taxpayer money, but it is understood that “the majority of Americans were not slave owners and even in the South, only one in five owned slaves,” more convincingly, “many Americans today have no connection to slavery at all since they immigrated here after 1865” (Source G). \nArguments could be made for the imbalance of reparations, as minorities such as Native American tribes have been given land and monetary reparations by the U.S. government. While these minorities have received reparations, these reparations directly to the victims. A table of previous reparations payments made to minorities/racially targeted groups that span from 1952-1990. The most recent and largest payment was in 1990, from the US government to Japanese American citizens, of $1.2 billion (about $20,000 each) in response to the Japanese encampments during World War II (Source D). While these payments were made to these minority groups, all these reparations were ordered while the original victims of the injustices were still alive, not over 150 years after the fact.\nThe complete dismissal of reparations, however, should not be administered. Focusing our attention on better ways to repay the descendants of slaves would be generally beneficial to the country, as Nathalie argued that descendants have no wealth. Given that a major source of wealth is inheritance, the lack of black property ownership means a less distinctive inheritance among black families for future generations (Nathalie). While reparations can be spent in the communities of descendants and underfunded black families, this affects people who may not be descendants, not specific to victims: “Recipients of reparations should be ‘the direct victims of the injustice or their immediate families’” (Source G). Despite this, former President Barack Obama stated that “the best reparations we can provide are good schools in the inner city and jobs for people who are unemployed,” and that those reparations could potentially “take the form of government programs to help struggling people of all races” (Source E). During her testimony, Michelle agreed, claiming that using reparations as a way of creating better schools and jobs for people who are struggling is a more beneficial way to use these monetary reparations (Michelle). Overall, the U.S. government, rather than distributing payments to individuals or communities, should focus on funding underprivileged or discriminated communities of traditionally black descendants, as this approach would create more opportunities and equality for discriminated black communities.",

        "evidence": "Our work is motivated by three major threads of research in machine learning and natural language processing: semantic-parsing for open-domain question answering, character-level language modeling, and encoder-decoder methods.\nSemantic parsing for open-domain question answering, which translates a question into a structured KB query, is a key component in question answering with a KB. While early approaches relied on building high-quality lexicons for domain-specific databases such as GeoQuery BIBREF7 , recent work has focused on building semantic parsing frameworks for general knowledge bases such as Freebase BIBREF1 , BIBREF8 , BIBREF0 , BIBREF9 , BIBREF2 .\nSemantic parsing frameworks for large-scale knowledge bases have to be able to successfully generate queries for the millions of entities and thousands of predicates in the KB, many of which are unseen during training. To address this issue, recent work relies on producing embeddings for predicates and entities in a KB based on their textual descriptions BIBREF8 , BIBREF0 , BIBREF1 , BIBREF10 . A general interaction function can then be used to measure the semantic relevance of these embedded KB entries to the question and determine the most likely KB query.\nMost of these approaches use word-level embeddings to encode entities and predicates, and therefore might suffer from the out-of-vocabulary (OOV) problem when they encounter unseen words during test time. Consequently, they often rely on significant data augmentation from sources such as Paralex BIBREF2 , which contains 18 million question-paraphrase pairs scraped from WikiAnswers, to have sufficient examples for each word they encounter BIBREF11 , BIBREF1 , BIBREF0 .\nAs opposed to word-level modeling, character-level modeling can be used to handle the OOV issue. While character-level modeling has not been applied to factoid question answering before, it has been successfully applied to information retrieval, machine translation, sentiment analysis, classification, and named entity recognition BIBREF12 , BIBREF13 , BIBREF6 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 , BIBREF19 . Moreover, gflstm demonstrate that gated-feedback LSTMs on top of character-level embeddings can capture long-term dependencies in language modeling.\nLastly, encoder-decoder networks have been applied to many structured machine learning tasks. First introduced in sutskever2014sequence, in an encoder-decoder network, a source sequence is first encoded with a recurrent neural network (RNN) into a fixed-length vector which intuitively captures its meaning, and then decoded into a desired target sequence. This approach and related memory-based or attention-based approaches have been successfully applied in diverse domains such as speech recognition, machine translation, image captioning, parsing, executing programs, and conversational dialogues BIBREF20 , BIBREF21 , BIBREF22 , BIBREF23 , BIBREF24 , BIBREF25 , BIBREF26 .\nUnlike previous work, we formulate question answering as a problem of decoding the KB query given the question and KB entries which are encoded in embedding spaces. We therefore integrate the learning of question and KB embeddings in a unified encoder-decoder framework, where the whole system is optimized end-to-end.\nOur work is motivated by three major threads of research in machine learning and natural language processing: semantic-parsing for open domain question answering, character-level language modeling, and encoder-decoder methods.",

Carter himself was a diligent student with a fondness for reading. A popular anecdote holds that he was passed over for valedictorian after he and his friends skipped school to venture downtown in a hot rod. Carter's truancy was mentioned in a local newspaper, although it is not clear he would have otherwise been valedictorian. As an adolescent, Carter played on the Plains High School basketball team, and also joined a youth organization named the Future Farmers of America, which helped him develop a lifelong interest in woodworking.\n\nCarter had long dreamed of attending the United States Naval Academy. In 1941, he started undergraduate coursework in engineering at Georgia Southwestern College in nearby Americus, Georgia. The following year, he transferred to the Georgia Institute of Technology in Atlanta, and he earned admission to the Naval Academy in 1943.  He was a good student but was seen as reserved and quiet, in contrast to the academy's culture of aggressive hazing of freshmen.  While at the academy, Carter fell in love with Rosalynn Smith, a friend of his sister Ruth. The two married shortly after his graduation in 1946. He was a sprint football player for the Navy Midshipmen. Carter graduated 60th out of 821 midshipmen in the class of 1947 with a Bachelor of Science degree and was commissioned as an ensign.",

        "evidence": "",
        "answer": "“Young lady! I demand you to come down this instant!” my stepmother demanded.\n“I’m busy!” I scream back from my room. I’m not actually busy, I’m just on my phone texting about the big party tonight. My friends and I are planning it out step by step, and hopefully at the end of the night, one of us will score a hot boy.\n“ You haven’t done any chores all month! I wish you were more like your step-sisters,” my stepmother continues angrily. The last part about my step-sisters really infuriated me. I storm downstairs ready to make a point that I’m not going to do chores for someone who isn’t my real mom.\n“Well maybe you're just jealous you didn’t peak in high school. I bet no one wanted to be your friend in school,” I argue. I put a smug look on my face, thinking that I totally just won this argument.\n“If you want to act like that I’ll give you the same treatment,” she warns me. She crosses her arms and taps her foot impatiently waiting for my response.\n“Whatever, if your're so fond of my step-sisters they can just do my chores,” I sigh as I roll my eyes.\n“You need to learn how to take care of yourself. Soon enough, your only achievement would be peaking in high school. You’re going to end up as a fast-food worker if you keep acting like this,” She reasons whilst she stares at me with daggers in her eyes.\n        \n                        “Fine, I’ll do the laundry. After I have to go to the mall, my friends and I are going dress shopping for the party,” I groan. I have to text my friends that I will be five minutes late. I grab my phone to message them.\n“Just the laundry isn’t enough for all of the chores you have ignored. You turn eighteen in two years, and you need to prepare for the real world. You will not go to the party; what you will do is stay here until you cleaned and organized the entire house to make up for the several years of not doing any chores at all,” She states.\nI can’t believe my ears. My life is literally ruined. She is seriously out to get me I swear. I flip my hair and start to walk over to my room.\n“I’m going to run some errands. When I’m back, I expect all the clothes to be folded, the kitchen wiped down, etcetera. Perhaps if you finish fast enough, you can still make it to the party. Maybe.” She orders and walks out of the house.\nThis is child abuse. I stomp my foot in frustration and call all my friends. I complain about all of the evil things my stepmother just did to me.\n                        “You should just sneak out, you do it all the time for parties,” One of my friend suggests.\n                “I would, but if my stepmother noticed I didn’t clean everything she’s probably going to take away my allowance and phone. You guys now I can’t live without those!” I point out. I pace back and forth around my room trying to think. I see an empty closet and get the perfect idea.\n           “What if I just throw in all the dirty things into the closet! That will give me enough time. She probably won’t notice for a couple of days. It’s flawless!” I proposed. Everyone agrees so I went straight to work. It only took me five minutes and I was out of the house and on my way to the mall. \n     —------------------------------------------------------------------------------\n          “Dress shopping was so fun! I’m glad I could make it.” I remarked. Everyone nods in agreement. I check the time on my phone.\n                “Guys! I didn’t realize it would take us that long to find out dresses, the parties in ten minutes!” I gasp, we all run into one of our cars and arrive to the party.\n                I look around the venue. This place looks so cool, there’s a dance floor in the middle where many people are at so I head there. I see a super handsome boy in the corner of my eye, I walk over to ask him to dance. He notices me too as I reach my hand out signaling we should dance. \n          We dance until our feet are sore. It is such a nice moment, I can’t wait to brag to my friends later. I go to take a seat with him but I see my mom enter the party. I quickly run out the door and the boy I just danced with starts following. My shoe falls off but I don’t stop running until I’m back home.\n —------------------------------------------------------\n     I wake up the next morning exhausted from last night. I look at the clock and it turns out I slept until 10 am. I walk downstairs to see my mom talking to someone at the door. I look to see who it was and it was the boy I danced with last night. How did he find me? \n                He sees me peeking and waves to me. He explains to me my friends also noticed my dramatic exit and told him where my house was. He then gets on his knees and takes out a ring.\n              “Will you marry me?” He asks me. I immediately knew my answer.\n                           “No”",

The crash was attributed to several factors, including market saturation in the number of video game consoles and available games, many of which were of poor quality, as well as waning interest in console games in favor of personal computers. Home video game revenues peaked at around $3.2 billion in 1983, then fell to around $100 million by 1985 (a drop of almost 97 percent). The crash abruptly ended what is retrospectively considered the second generation of console video gaming in North America. To a lesser extent, the arcade video game market also weakened as the golden age of arcade video games came to an end.\n\nLasting about two years, the crash shook a then-booming video game industry and led to the bankruptcy of several companies producing home computers and video game consoles. Analysts of the time expressed doubts about the long-term viability of video game consoles and software.\n\nThe North American video game console industry recovered a few years later, mostly due to the widespread success of Nintendo's Western branding for its Famicom console, the Nintendo Entertainment System (NES), released in 1985. The NES was designed to avoid the missteps that caused the 1983 crash and the stigma associated with video games at that time.",

After Marty's band fails a music audition, he confides in his girlfriend, Jennifer Parker, that he fears becoming like his parents despite his ambitions.\n\nThat night, Marty meets his eccentric scientist friend, Emmett \"Doc\" Brown, in the Twin Pines mall parking lot. Doc unveils a time machine built from a modified DeLorean, powered by plutonium he swindled from Libyan terrorists. After Doc inputs a destination time of November 5, 1955 (the day he first conceived his time travel invention), the terrorists arrive unexpectedly and gun him down. Marty flees in the DeLorean, inadvertently activating time travel when he reaches 88 miles per hour (142 kilometers per hour).\n\nArriving in 1955, Marty discovers he has no plutonium to return. While exploring a burgeoning Hill Valley, Marty encounters his teenage father and discovers Biff was bullying George even then. George falls into the path of an oncoming car while spying on the teenage Lorraine changing clothes, and Marty is knocked unconscious while saving him. He wakes to find himself tended to by Lorraine, who becomes infatuated with him. Marty tracks down and convinces a younger Doc that he is from the future, but Doc explains the only source available in 1955 capable of generating the power required for time travel is a lightning bolt. Marty shows Doc a flyer from the future that documents an upcoming lightning strike at the town's courthouse. As Marty's siblings begin to fade from a photo he is carrying with him, Doc realizes Marty's actions are altering the future and jeopardizing his existence; Lorraine was supposed to tend to George instead of Marty after the car accident. Early attempts to get his parents acquainted fail, and Lorraine's infatuation with Marty deepens.\n\nLorraine asks Marty to the school dance, and he plots to feign inappropriate advances on her, allowing George to intervene and rescue her, but the plan goes awry when Biff's gang locks Marty in the trunk of the performing band's car, while Biff forces himself onto Lorraine. George arrives expecting to find Marty but is assaulted by Biff. After Biff hurts Lorraine, an enraged George knocks him unconscious and escorts the grateful Lorraine to the dance. The band frees Marty from their car, but the lead guitarist injures his hand in the process, so Marty takes his place, performing while George and Lorraine share their first kiss. With his future no longer in jeopardy, Marty heads to the courthouse to meet Doc.\n\nDoc discovers a letter from Marty warning him about his future and rips it, worried about the consequences. To save Doc, Marty recalibrates the DeLorean to return ten minutes before he left the future. The lightning strikes, sending Marty back to 1985, but the DeLorean breaks down, forcing Marty to run back to the mall. He arrives as Doc is being shot. While Marty grieves at his side, Doc sits up, revealing he pieced Marty's note back together and wore a bulletproof vest. He takes Marty home and departs to 2015 in the DeLorean. Marty wakes the next morning to discover his father is now a confident and successful science fiction author, his mother is fit and happy, his siblings are successful, and Biff is a servile valet in George's employ. As Marty reunites with Jennifer, Doc suddenly reappears in the DeLorean, insisting they return with him to the future to save their children from terrible fates.",

        "evidence": "Simulated racing or racing simulation, commonly known as simply sim racing, are the collective terms for racing game software that attempts to accurately simulate auto racing, complete with real-world variables such as fuel usage, damage, tire wear and grip, and suspension settings. To be competitive in sim racing, a driver must understand all aspects of car handling that make real-world racing so difficult, such as threshold braking, how to maintain control of a car as the tires lose traction, and how properly to enter and exit a turn without sacrificing speed. It is this level of difficulty that distinguishes sim racing from arcade racing-style driving games where real-world variables are taken out of the equation and the principal objective is to create a sense of speed as opposed to a sense of realism.\n\n\nJann Mardenborough, a sim racer became a professional Nissan racing driver by playing Gran Turismo.\nDue to the complexity and demands of mimicking real-life driving, racing sims require faster computers to run effectively, as well as a steering wheel and pedals for the throttle and brakes for the immersion.\n\n\nMany cars are digitally recreated for sim racing like this BMW Z4 GT3 from Assetto Corsa.\nWhile using a simple gamepad, joystick or even a mouse and keyboard may suffice for most arcade-style driving games on home systems, it won't provide the same level of immersion and realism as using a racing wheel and pedals. In recent years, many sim racing experiences have been developed for consoles, such as the PlayStation and Xbox. While these games can be played with a controller, it is recommended that players invest in a racing wheel and pedals. With the development of online racing, the ability to drive against human opponents and computer AI offline is the closest many will come to driving cars on a real track. Even those who race in real-world competition use simulations for practice or for entertainment. With continued development of the physics engine software that forms the basis of these sims, as well as improved hardware (providing tactile feedback), the experience has become more realistic.\n\nIn general, sim racing gameplay style applied in several video games like iRacing, Assetto Corsa and Assetto Corsa Competizione, Gran Turismo, among others.",

        "answer": "No.",
        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nWe introduce the Transformer encoder in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning",

        "evidence": "We compare our two exploration strategies to the following baselines and ablations:\nKG-A2C This is the exact same method presented in BIBREF6 with no modifications.\nA2C Represents the same approach as KG-A2C but with all the knowledge graph components removed. The state representation is text only encoded using recurrent networks.\nA2C-chained Is a variation on KG-A2C-chained where we use our policy chaining approach with the A2C method to train the agent instead of KG-A2C.\nA2C-Explore Uses A2C in addition to the exploration strategy seen in KG-A2C-Explore. The cell representations here are defined in terms of the recurrent network based encoding of the textual observation.\nFigure FIGREF10 shows that agents utilizing knowledge-graphs in addition to either enhanced exploration method far outperform the baseline A2C and KG-A2C. KG-A2C-chained and KG-A2C-Explore both pass the bottleneck of a score of 40, whereas A2C-Explore gets to the bottleneck but cannot surpass it.\nThere are a couple of key insights that can be drawn from these results The first is that the knowledge graph appears to be critical; it is theorized to help with partial observability. However the knowledge graph representation isn't sufficient in that the knowledge graph representation without enhanced exploration methods cannot surpass the bottleneck. A2C-chained—which explores without a knowledge graph—fails to even outperform the baseline A2C. We hypothesize that this is due to the knowledge graph aiding implicitly in the sample efficiency of bottleneck detection and subsequent exploration. That is, exploring after backtracking from a potentially detected bottleneck is much more efficient in the knowledge graph based agent.\nThe Go-Explore based exploration algorithm sees less of a difference between agents. A2C-Explore converges more quickly, but to a lower reward trajectory that fails to pass the bottleneck, whereas KG-A2C-Explore takes longer to reach a similar reward but consistently makes it through the bottleneck. The knowledge graph cell representation appears to thus be a better indication of what a promising state is as opposed to just the textual observation.\nComparing the advanced exploration methods when using the knowledge graph, we see that both agents successfully pass the bottleneck corresponding to entering the cellar and lighting the lamp and reach comparable scores within a margin of error. KG-A2C-chained is significantly more sample efficient and converges faster. We can infer that chaining policies by explicitly detecting bottlenecks lets us pass it more quickly than attempting to find promising cell representations with Go-Explore. This form of chained exploration with backtracking is particularly suited to sequential decision making problems that can be represented as acyclic directed graphs as in Figure FIGREF1.\nWe hypothesize that this is due to the knowledge graph aiding implicitly in the sample efficiency of bottleneck detection and subsequent exploration.",

Hong Kong SAR or HKSAR), is a city and special administrative region of China on the eastern Pearl River Delta in South China. With 7.5 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated places in the world. Hong Kong is also a major global financial centre and one of the most developed cities in the world.\n\nHong Kong was established as a colony of the British Empire after the Qing Empire ceded Hong Kong Island from Xin'an County at the end of the First Opium War in 1841 then again in 1842. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898. British Hong Kong was occupied by Imperial Japan from 1941 to 1945 during World War II; British administration resumed after the surrender of Japan. The whole territory was transferred to China in 1997. As one of China's two special administrative regions (the other being Macau), Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of \"one country, two systems\".\n\nOriginally a sparsely populated area of farming and fishing villages, the territory has become one of the world's most significant financial centres and commercial ports. As of 2021, it is the world's ninth-largest exporter and eight-largest importer. Hong Kong has a market economy characterised by a focus on services, low taxation and free trade; its currency, the Hong Kong dollar, is the eighth most traded currency in the world. Hong Kong is home to the third-highest number of billionaires of any city in the world, the second-highest number of billionaires of any city in Asia, and the largest concentration of ultra high-net-worth individuals of any city in the world. Although the city has one of the highest per capita incomes in the world, severe income inequality exists among the population. Most notably, housing in Hong Kong has been well-documented to experience a chronic persistent shortage; the extremely compact house sizes and the extremely high housing density are the effects of Hong Kong's housing market being the most expensive housing in the world.\n\nHong Kong is a highly developed territory and has a Human Development Index (HDI) of 0.952, ranking fourth in the world. The city has the largest number of skyscrapers of any city in the world, and its residents have some of the highest life expectancies in the world.

In 2014, kimconvolutional2014 proposed to use one convolutional neural network for sentence classification, he fixed the size of the input sentence and concatenated its word embeddings for representing the sentence, this architecture has been exploited in many later works. severynunitn:2015 adapted the convolutional network proposed by kimconvolutional2014 for sentiment analysis in Twitter, their system was ranked second in SemEval-2015 while the first system BIBREF3 combined four systems based on feature extraction and the third ranked system used logistic regression with different groups of features BIBREF2 .\nIn 2016, we remark that the number of participations which use feature extraction systems were degraded, and the first four systems used Deep Learning, the majority used a convolutional network except the fourth one BIBREF4 . Despite of that, using Deep Learning for sentiment analysis in Twitter has not yet shown a big improvement in comparison to feature extraction, the fifth and sixth systems BIBREF5 in 2016 which were built upon feature extraction process were only (3 and 3.5% respectively) less than the first system.

Therefore, we proposed to use convolutional networks for Twitter polarity classification.\nOur proposed system consists of a convolutional layer followed by fully connected layer and a softmax on top. This is inspired by kimconvolutional2014, we just added a fully connected layer. This architecture gives a good performance but it could be improved. Regarding the best system in 2016 BIBREF6 , it uses different word embeddings for initialisation then it combines the predictions of different nets using a meta-classifier, Word2vec and Glove have been used to vary the tweet representation.\nIn our work, we propose to vary the neural network weights instead of tweet representation which can get the same effect of varying the word embeddings, therefore we vary the initial weights of the network to produce ten different nets, a voting system over the these ten voters will decide the sentiment label for a tweet.\nThe remaining of this paper is organized as follows: Section 2 describes the system architecture, Section 3 presents our experiments and results and Section 4 is devoted for the conclusion.\nBut We think that Deep Learning is a promising direction in sentiment analysis.

BioIE systems aim to extract information from a wide spectrum of articles including medical literature, biological literature, electronic health records, etc. that can be used by clinicians and researchers in the field. Often the outputs of BioIE systems are used to assist in the creation of databases, or to suggest new paths for research. For example, a ranked list of interacting proteins that are extracted from biomedical literature, but are not present in existing databases, can allow researchers to make informed decisions about which protein/gene to study further. Interactions between drugs are necessary for clinicians who simultaneously administer multiple drugs to their patients. A database of diseases, treatments and tests is beneficial for doctors consulting in complicated medical cases.\nThe main problems in BioIE are similar to those in Information Extraction:\nThis paper discusses, in each section, various methods that have been adopted to solve the listed problems. Each section also highlights the difficulty of Information Extraction tasks in the biomedical domain.\nThis paper is intended as a primer to Biomedical Information Extraction for current NLP researchers. It aims to highlight the diversity of the various techniques from Information Extraction that have been applied in the Biomedical domain. The state of biomedical text mining is reviewed regularly.

        "answer": "A number of transformation and scoring algorithms.",
        "evidence": "The need to access and digest large amounts of textual data has provided strong impetus to develop automatic summarization systems aiming to create shorter versions of one or more documents, whilst preserving their information content. Much effort in automatic summarization has been devoted to sentence extraction, where a summary is created by identifying and subsequently concatenating the most salient text units in a document.\nMost extractive methods to date identify sentences based on human-engineered features. These include surface features such as sentence position and length BIBREF0 , the words in the title, the presence of proper nouns, content features such as word frequency BIBREF1 , and event features such as action nouns BIBREF2 . Sentences are typically assigned a score indicating the strength of presence of these features. Several methods have been used in order to select the summary sentences ranging from binary classifiers BIBREF3 , to hidden Markov models BIBREF4 , graph-based algorithms BIBREF5 , BIBREF6 , and integer linear programming BIBREF7 .\nIn this work we propose a data-driven approach to summarization based on neural networks and continuous sentence features. There has been a surge of interest recently in repurposing sequence transduction neural network architectures for NLP tasks such as machine translation BIBREF8 , question answering BIBREF9 , and sentence compression BIBREF10 . Central to these approaches is an encoder-decoder architecture modeled by recurrent neural networks. The encoder reads the source sequence into a list of continuous-space representations from which the decoder generates the target sequence. An attention mechanism BIBREF11 is often used to locate the region of focus during decoding.\nWe develop a general framework for single-document summarization which can be used to extract sentences or words. Our model includes a neural network-based hierarchical document reader or encoder and an attention-based content extractor. The role of the reader is to derive the meaning representation of a document based on its sentences and their constituent words. Our models adopt a variant of neural attention to extract sentences or words. Contrary to previous work where attention is an intermediate step used to blend hidden units of an encoder to a vector propagating additional information to the decoder, our model applies attention directly to select sentences or words of the input document as the output summary. Similar neural attention architectures have been previously used for geometry reasoning BIBREF12 , under the name Pointer Networks.\nOne stumbling block to applying neural network models to extractive summarization is the lack of training data, i.e., documents with sentences (and words) labeled as summary-worthy. Inspired by previous work on summarization BIBREF7 , BIBREF13 and reading comprehension BIBREF9 we retrieve hundreds of thousands of news articles and corresponding highlights from the DailyMail website. Highlights usually appear as bullet points giving a brief overview of the information contained in the article (see Figure 1 for an example). Using a number of transformation and scoring algorithms, we are able to match highlights to document content and construct two large scale training datasets, one for sentence extraction and the other for word extraction. Previous approaches have used small scale training data in the range of a few hundred examples.\nOur work touches on several strands of research within summarization and neural sequence modeling. The idea of creating a summary by extracting words from the source document was pioneered in bankoetal00 who view summarization as a problem analogous to statistical machine translation and generate headlines using statistical models for selecting and ordering the summary words. Our word-based model is similar in spirit, however, it operates over continuous representations, produces multi-sentence output, and jointly selects summary words and organizes them into sentences. A few recent studies BIBREF14 , BIBREF15 perform sentence extraction based on pre-trained sentence embeddings following an unsupervised optimization paradigm. Our work also uses continuous representations to express the meaning of sentences and documents, but importantly employs neural networks more directly to perform the actual summarization task.\nrush2015neural propose a neural attention model for abstractive sentence compression which is trained on pairs of headlines and first sentences in an article. In contrast, our model summarizes documents rather than individual sentences, producing multi-sentential discourse. A major architectural difference is that our decoder selects output symbols from the document of interest rather than the entire vocabulary. This effectively helps us sidestep the difficulty of searching for the next output symbol under a large vocabulary, with low-frequency words and named entities whose representations can be challenging to learn. Gu:ea:16 and gulcehre2016pointing propose a similar “copy” mechanism in sentence compression and other tasks; their model can accommodate both generation and extraction by selecting which sub-sequences in the input sequence to copy in the output.\nWe evaluate our models both automatically (in terms of Rouge) and by humans on two datasets: the benchmark DUC 2002 document summarization corpus and our own DailyMail news highlights corpus. Experimental results show that our summarizers achieve performance comparable to state-of-the-art systems employing hand-engineered features and sophisticated linguistic constraints.\nUsing a number of transformation and scoring algorithms, we are able to match highlights to document content and construct two large scale training datasets, one for sentence extraction and the other for word extraction.",

Borrowing the idea of universal lexical sharing from BIBREF11, we represent each foreign word embedding $_f[i] \\in ^d$ as a linear combination of English word embeddings $_e[j] \\in ^d$\nwhere $_i\\in ^{|V_e|}$ is a sparse vector and $\\sum _j^{|V_e|} \\alpha _{ij} = 1$.\nIn this step of initializing foreign embeddings, having a good estimation of $$ could speed of the convergence when tuning the foreign model and enable zero-shot transfer (§SECREF5).

        "evidence": "We aimed to mimic the presence of sparse/noisy content distribution, mandating the need to curate a novel dataset via specific lexicons. We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation. With increasing the number of iterations, the pool of seed phrases gets refined and augments the selection of transport relevant tweets. The proposed pipeline is tailored to identify complaint relevant tweets in a noisy scenario.\nThe redundant tweets were filtered based on the cosine similarity score.",

        "question": "Given these paragraphs about Multiomics, what is single-cell multiomics?",
        "evidence": "Multiomics, multi-omics, integrative omics, \"panomics\" or \"pan-omics\" is a biological analysis approach in which the data sets are multiple \"omes\", such as the genome, proteome, transcriptome, epigenome, metabolome, and microbiome (i.e., a meta-genome and/or meta-transcriptome, depending upon how it is sequenced); in other words, the use of multiple omics technologies to study life in a concerted way. By combining these \"omes\", scientists can analyze complex biological big data to find novel associations between biological entities, pinpoint relevant biomarkers and build elaborate markers of disease and physiology. In doing so, multiomics integrates diverse omics data to find a coherently matching geno-pheno-envirotype relationship or association. The OmicTools service lists more than 99 softwares related to multiomic data analysis, as well as more than 99 databases on the topic.\n\nSystems biology approaches are often based upon the use of panomic analysis data. The American Society of Clinical Oncology (ASCO) defines panomics as referring to \"the interaction of all biological functions within a cell and with other body functions, combining data collected by targeted tests ... and global assays (such as genome sequencing) with other patient-specific information.\"\n\nSingle-cell multiomics\nA branch of the field of multiomics is the analysis of multilevel single-cell data, called single-cell multiomics. This approach gives us an unprecedent resolution to look at multilevel transitions in health and disease at the single cell level. An advantage in relation to bulk analysis is to mitigate confounding factors derived from cell to cell variation, allowing the uncovering of heterogeneous tissue architectures.\n\nMethods for parallel single-cell genomic and transcriptomic analysis can be based on simultaneous amplification or physical separation of RNA and genomic DNA. They allow insights that cannot be gathered solely from transcriptomic analysis, as RNA data do not contain non-coding genomic regions and information regarding copy-number variation, for example. An extension of this methodology is the integration of single-cell transcriptomes to single-cell methylomes, combining single-cell bisulfite sequencing to single cell RNA-Seq. Other techniques to query the epigenome, as single-cell ATAC-Seq and single-cell Hi-C also exist.\n\nA different, but related, challenge is the integration of proteomic and transcriptomic data. One approach to perform such measurement is to physically separate single-cell lysates in two, processing half for RNA, and half for proteins. The protein content of lysates can be measured by proximity extension assays (PEA), for example, which use DNA-barcoded antibodies. A different approach uses a combination of heavy-metal RNA probes and protein antibodies to adapt mass cytometry for multiomic analysis.\n\nMultiomics and machine learning\nIn parallel to the advances in highthroughput biology, machine learning applications to biomedical data analysis are flourishing. The integration of multi-omics data analysis and machine learning has led to the discovery of new biomarkers. For example, one of the methods of the mixOmics project implements a method based on sparse Partial Least Squares regression for selection of features (putative biomarkers).\n\n\nhttps://en.wikipedia.org/wiki/Multiomics",

While NMT is generally more fluent than previous statistical systems, adequacy is still a major concern BIBREF4 : common mistakes include dropping source words and repeating words in the generated translation.\nPrevious work has attempted to mitigate this problem in various ways. BIBREF5 incorporate coverage and length penalties during beam search—a simple yet limited solution, since it only affects the scores of translation hypotheses that are already in the beam. Other approaches involve architectural changes: providing coverage vectors to track the attention history BIBREF6 , BIBREF7 , using gating architectures and adaptive attention to control the amount of source context provided BIBREF8 , BIBREF9 , or adding a reconstruction loss BIBREF10 . BIBREF11 also use the notion of fertility implicitly in their proposed model. Their “fertility conditioned decoder” uses a coverage vector and an “extract gate” which are incorporated in the decoding recurrent unit, increasing the number of parameters.\nIn this paper, we propose a different solution that does not change the overall architecture, but only the attention transformation. Namely, we replace the traditional softmax by other recently proposed transformations that either promote attention sparsity BIBREF12 or upper bound the amount of attention a word can receive BIBREF13 . The bounds are determined by the fertility values of the source words. While these transformations have given encouraging results in various NLP problems, they have never been applied to NMT, to the best of our knowledge. Furthermore, we combine these two ideas and propose a novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments. While being in-between soft and hard alignments (Figure FIGREF20 ), the constrained sparsemax transformation is end-to-end differentiable, hence amenable for training with gradient backpropagation.\nTo sum up, our contributions are as follows:\nWhile NMT is generally more fluent than previous sta-tistical systems, adequacy is still a major concern (Koehn and Knowles, 2017): common mis-takes include dropping source words and repeating words in the generated translation.",

        "evidence": "Automatic classification of sentiment has mainly focused on categorizing tweets in either two (binary sentiment analysis) or three (ternary sentiment analysis) categories BIBREF0 . In this work we study the problem of fine-grained sentiment classification where tweets are classified according to a five-point scale ranging from VeryNegative to VeryPositive. To illustrate this, Table TABREF3 presents examples of tweets associated with each of these categories. Five-point scales are widely adopted in review sites like Amazon and TripAdvisor, where a user's sentiment is ordered with respect to its intensity. From a sentiment analysis perspective, this defines a classification problem with five categories. In particular, Sebastiani et al. BIBREF1 defined such classification problems whose categories are explicitly ordered to be ordinal classification problems. To account for the ordering of the categories, learners are penalized according to how far from the true class their predictions are.\nAlthough considering different scales, the various settings of sentiment classification are related. First, one may use the same feature extraction and engineering approaches to represent the text spans such as word membership in lexicons, morpho-syntactic statistics like punctuation or elongated word counts BIBREF2 , BIBREF3 . Second, one would expect that knowledge from one task can be transfered to the others and this would benefit the performance. Knowing that a tweet is “Positive” in the ternary setting narrows the classification decision between the VeryPositive and Positive categories in the fine-grained setting. From a research perspective this raises the question of whether and how one may benefit when tackling such related tasks and how one can transfer knowledge from one task to another during the training phase.\nOur focus in this work is to exploit the relation between the sentiment classification settings and demonstrate the benefits stemming from combining them. To this end, we propose to formulate the different classification problems as a multitask learning problem and jointly learn them. Multitask learning BIBREF4 has shown great potential in various domains and its benefits have been empirically validated BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 using different types of data and learning approaches. An important benefit of multitask learning is that it provides an elegant way to access resources developed for similar tasks. By jointly learning correlated tasks, the amount of usable data increases. For instance, while for ternary classification one can label data using distant supervision with emoticons BIBREF9 , there is no straightforward way to do so for the fine-grained problem. However, the latter can benefit indirectly, if the ternary and fine-grained tasks are learned jointly.\nThe research question that the paper attempts to answer is the following: Can twitter sentiment classification problems, and fine-grained sentiment classification in particular, benefit from multitask learning? To answer the question, the paper brings the following two main contributions: (i) we show how jointly learning the ternary and fine-grained sentiment classification problems in a multitask setting improves the state-of-the-art performance, and (ii) we demonstrate that recurrent neural networks outperform models previously proposed without access to huge corpora while being flexible to incorporate different sources of data.\n(i) we show how jointly learning the ternary and fine-grained sentiment classification problems in a multitask setting improves the state-of-the-art performance, and (ii) we demonstrate that recurrent neural networks outperform models previously proposed without access to huge corpora while being flexible to incorporate different sources of data.",

We find these scores remarkably high given our straight-forward average-pooling strategy and that no domain-supervision was involved in the process of learning the pre-trained representations. Figure FIGREF15 also demonstrates the quality of the obtained clusters in 2D using the BERT-base model, where the ellipses describe the mean and variance parameters learned for each cluster by the GMM with $k=5$.\nWe note that some classes of models did better than others: while all vector-based models did far better than the random and LDA baselines, the MLM-based models dominated in all cases over word2vec and the auto-regressive models. This may be explained by the fact that the MLM-based models use the entire sentence context when generating the representations for each token, while the auto-regressive models only use the past context, and word2vec uses a limited window context. Using PCA improved performance in most cases and especially for the auto-regressive models, although the results for the MLMs remain high in both cases – suggesting that these models encode the information very differently.\nThe results are available in Table TABREF32. We can see that all selection methods performed much better in terms of BLEU than random selection. It is also nice to see that all selection methods performed better than using all the available data or the oracle-selected data when averaged across all domains, showing again that more data is not necessarily better in multi-domain scenarios and that data selection is a useful approach.

        "evidence": "Using llamas as livestock guards in North America began in the early 1980s, and some sheep producers have used llamas successfully since then. Some would even use them to guard their smaller cousins, the alpaca. They are used most commonly in the western regions of the United States, where larger predators, such as coyotes and feral dogs, are prevalent. Typically, a single gelding (castrated male) is used.\n\nResearch suggests the use of multiple guard llamas is not as effective as one. Multiple males tend to bond with one another, rather than with the livestock, and may ignore the flock. A gelded male of two years of age bonds closely with its new charges and is instinctively very effective in preventing predation. Some llamas appear to bond more quickly to sheep or goats if they are introduced just prior to lambing. Many sheep and goat producers indicate a special bond quickly develops between lambs and their guard llama and the llama is particularly protective of the lambs.\n\nUsing llamas as guards has reduced the losses to predators for many producers. The value of the livestock saved each year more than exceeds the purchase cost and annual maintenance of a llama. Although not every llama is suited to the job, most are a viable, nonlethal alternative for reducing predation, requiring no training and little care.",

        "question": "How does BERT and Transformer-XL experiments was trained?",
        "answer": "Both BERT and Transformer-XL experiments were trained for 500K steps.",
        "evidence": "All BERT experiments were trained for 500K steps. The code was written in Python and we used the Tensorflow libraries to create the models. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. The data was first processed into Tensorflow records as the input to the model. The set of hyperparameters which we found optimal after experimenting with different sets are in (Table TABREF10).\nThis set of parameters were chosen as there training performances were better than smaller models on modelling the long sequences of sub-words. We use the Adam optimizer BIBREF16 same as the English BERT. A maximum sequence length of 300 encompasses 98 percent of the training data and also allows us to fit larger models on the GPU card. Hyper-parameter optimization is very difficult in case of these models as they take around 15 days to train given the resources. The hyperparameter choices were therefore more dependant on the original BERT with little tweaks. We assess the training performance of the the model in the (Table TABREF11).\nWhen we train the BERT model we mask some percentage of the input tokens at random, and then predict those masked tokens, this is known as Masked LM. The masked LM loss, refers specifically to the loss when the masked language model predicts on the masked tokens. The masked LM accuracy refers specifically to the accuracy with which the model predicts on the masked tokens. The loss for both the models are far off from the Masked LM loss of the English BERT, key difference being the pre-training data for both the language models are quite different. Google training their model on 3.3 Billion words from BooksCorpus BIBREF17 and the English Wikipedia and our model being trained on 144 million words. Comparing the two Finnish models, the left-marked model has a better training performance than left+right-marked model.\nThe results of the pseudo-perplexity described in the previous section to evaluate the above models on the test data-set is in table (Table TABREF12).The test dataset is of a different context when compared to the training data, and interestingly both the models are quite confident when it comes to the test dataset. The pseudo-perplexity values of left-marked are lower when compared to left-right-marked signifying that it is more confident.\nWe cannot directly compare the perplexity scores BERT model with a unidirectional LSTM model as both are calculated in a different manner. We can experiment to compare it with a Bi-directional LSTM or use a downstreaming task to compare both the performances. We could also randomly mask tokens and then compare the prediction accuracy on the masked tokens.\nAll Transformer-XL experiments are also trained equally for 500K steps. The code was written in Python and we used the PyTorch libraries for model creation. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. Two sets of hyperparameters were chosen to be compared after some initial optimization and are in (Table TABREF14)\nFrom the above parameter choice, we wanted to experiment, whether providing more Segment and Memory length is advantageous (longer context) than a larger model. These parameters where chosen after some hyperparameter optimization. Same as for BERT we use the Adam optimizer, but we also use a cosine annealing learning rate scheduler to speed-up training BIBREF18. The training performance results are in (Table TABREF15)\nAs opposed to BERT, the left+right-marked models have a better training performance than their counterpart. Interestingly the larger model trains much better when compared to providing larger contexts. The same set of parameters for the 32-32 model cannot be replicated for 150-150 model as the latter takes a lot of space on the GPU card. The test set is same as that used with BERT and the results are in (Table TABREF16). The test performance is similar to that of the training performance with left-right-marked large model(32-32) performing the best. We can directly compare the perplexity scores with the previous best BIBREF19 as both are unidirectional models, Transformer-XL model has outperformed the latter by 27%.\nAll BERT experiments were trained for 500K steps. ****All Transformer-XL experiments are also trained equally for 500K steps.",

        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nAutomatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences [23, 1, 28], which always end with a period (“.”) in English [10].",

More importantly, however, the constraint that the game only ends if they both agree ensures a “committment symmetry”, where the success of the game must be ensured by both participants. The design also provides for a clear “relevance place” at which an opportunity arises for semantic negotiation, namely, before the final decision is made. An example of this is shown in the example below. (The number in the parentheses indicate the time, relative to the beginning of the interaction, when the utterance was made.)\nThe MatchIt Game (Ilinykh et al., forthcoming) is a yet further simplified visual game. Here, the goal simply is to decide whether you and your partner are both looking at the same image (of the same genre as in MeetUp). In that sense, it is a reduction of the MeetUP game to the final stage, taking out the navigation aspect. As example SECREF12 shows, this can similarly lead to meta-semantic interaction, where classifications are revised.

Sentence simplification has a number of practical applications. On one hand, it provides reading aids for people with limited language proficiency BIBREF1 , BIBREF2 , or for patients with linguistic and cognitive disabilities BIBREF3 . On the other hand, it can improve the performance of other NLP tasks BIBREF4 , BIBREF5 , BIBREF6 . Prior work has explored monolingual machine translation (MT) approaches, utilizing corpora of simplified texts, e.g., Simple English Wikipedia (SEW), and making use of statistical MT models, such as phrase-based MT (PBMT) BIBREF7 , BIBREF8 , BIBREF9 , tree-based MT (TBMT) BIBREF10 , BIBREF11 , or syntax-based MT (SBMT) BIBREF12 .\nInspired by the success of neural MT BIBREF13 , BIBREF14 , recent work has started exploring neural simplification with sequence to sequence (Seq2seq) models, also referred to as encoder-decoder models. Nisioi et al. Nisioi:17 implemented a standard LSTM-based Seq2seq model and found that they outperform PBMT, SBMT, and unsupervised lexical simplification approaches. Zhang and Lapata BIBREF15 viewed the encoder-decoder model as an agent and employed a deep reinforcement learning framework in which the reward has three components capturing key aspects of the target output: simplicity, relevance, and fluency. The common practice for Seq2seq models is to use recurrent neural networks (RNNs) with Long Short-Term Memory BIBREF16 or Gated Recurrent Unit BIBREF17 for the encoder and decoder BIBREF18 , BIBREF15 . These architectures were designed to be capable of memorizing long-term dependencies across sequences. Nevertheless, their memory is typically small and might not be enough for the simplification task, where one is confronted with long and complicated sentences. In this study, we go beyond the conventional LSTM/GRU-based Seq2seq models and propose to use a memory-augmented RNN architecture called Neural Semantic Encoders (NSE). This architecture has been shown to be effective in a wide range of NLP tasks BIBREF0 . The contribution of this paper is twofold:\n(1) First, we present a novel simplification model which is, to the best of our knowledge, the first model that use memory-augmented RNN for the task. We investigate the effectiveness of neural Seq2seq models when different neural architectures for the encoder are considered. Our experiments reveal that the NseLstm model that uses an NSE as the encoder and an LSTM as the decoder performed the best among these models, improving over strong simplification systems. (2) Second, we perform an extensive evaluation of various approaches proposed in the literature on different datasets. Results of both automatic and human evaluation show that our approach is remarkably effective for the task, significantly reducing the reading difficulty of the input, while preserving grammaticality and the original meaning. We further discuss some advantages and disadvantages of these approaches.\n(1) First, we present a novel simplification model which is, to the best of our knowledge, the first model that use memory-augmented RNN for the task.",

        "evidence": "We compare performances of our model with the implementation of BIBREF13 and the results are shown in Table TABREF43 . Our model obtains better performances in Multi-Domain scenario with an average improvement of 4.5%, where datasets are product reviews on different domains with similar sequence lengths and the same class number, thus producing stronger correlations. Multi-Cardinality scenario also achieves significant improvements of 2.77% on average, where datasets are movie reviews with different cardinalities.\nHowever, Multi-Objective scenario benefits less from multi-task learning due to lacks of salient correlation among sentiment, topic and question type. The QC dataset aims to classify each question into six categories and its performance even gets worse, which may be caused by potential noises introduced by other tasks. In practice, the structure of our model is flexible, as couplings and fusions between some empirically unrelated tasks can be removed to alleviate computation costs.\nWe further explore the influence of INLINEFORM0 in TOS on our model, which can be any positive integer. A higher value means larger and more various samples combinations, while requires higher computation costs.\nFigure FIGREF45 shows the performances of datasets in Multi-Domain scenario with different INLINEFORM0 . Compared to INLINEFORM1 , our model can achieve considerable improvements when INLINEFORM2 as more samples combinations are available. However, there are no more salient gains as INLINEFORM3 gets larger and potential noises from other tasks may lead to performance degradations. For a trade-off between efficiency and effectiveness, we determine INLINEFORM4 as the optimal value for our experiments.\nIn order to measure the correlation strength between two task INLINEFORM0 and INLINEFORM1 , we learn them jointly with our model and define Pair-wise Performance Gain as INLINEFORM2 , where INLINEFORM3 are the performances of tasks INLINEFORM4 and INLINEFORM5 when learned individually and jointly.\nWe calculate PPGs for every two tasks in Table TABREF35 and illustrate the results in Figure FIGREF47 , where darkness of colors indicate strength of correlation. It is intuitive that datasets of Multi-Domain scenario obtain relatively higher PPGs with each other as they share similar cardinalities and abundant low-level linguistic characteristics. Sentences of QC dataset are much shorter and convey unique characteristics from other tasks, thus resulting in quite lower PPGs.\nHowever, Multi-Objective scenario benefits less from multi-task learning due to lacks of salient correlation among sentiment, topic and question type.",

        "evidence": "The Indus Valley Civilisation (IVC), also known as the Indus Civilisation was a Bronze Age civilisation in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE, and in its mature form 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread. Its sites spanned an area from much of Pakistan, to northeast Afghanistan, and northwestern India. The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan.\n\nThe term Harappan is sometimes applied to the Indus civilisation after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab province of British India and is now Punjab, Pakistan. The discovery of Harappa and soon afterwards Mohenjo-daro was the culmination of work that had begun after the founding of the Archaeological Survey of India in the British Raj in 1861. There were earlier and later cultures called Early Harappan and Late Harappan in the same area. The early Harappan cultures were populated from Neolithic cultures, the earliest and best-known of which is Mehrgarh, in Balochistan, Pakistan. Harappan civilisation is sometimes called Mature Harappan to distinguish it from the earlier cultures.\n\nThe cities of the ancient Indus were noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, clusters of large non-residential buildings, and techniques of handicraft and metallurgy. Mohenjo-daro and Harappa very likely grew to contain between 30,000 and 60,000 individuals, and the civilisation may have contained between one and five million individuals during its florescence. A gradual drying of the region during the 3rd millennium BCE may have been the initial stimulus for its urbanisation. Eventually it also reduced the water supply enough to cause the civilisation's demise and to disperse its population to the east.\n\nAlthough over a thousand Mature Harappan sites have been reported and nearly a hundred excavated, there are five major urban centres: Mohenjo-daro in the lower Indus Valley (declared a UNESCO World Heritage Site in 1980 as \"Archaeological Ruins at Moenjodaro\"), Harappa in the western Punjab region, Ganeriwala in the Cholistan Desert, Dholavira in western Gujarat (declared a UNESCO World Heritage Site in 2021 as \"Dholavira: A Harappan City\"), and Rakhigarhi in Haryana.

        "question": "Does the synperiodic filterbank consider the physical characteristics of sound receiver system?",
        "answer": "Our proposed synperiodic filterbank is designed to process mono-channel waveform. For inter-channel interaction, we encode the phase difference on the time-frequency representation extracted by synperiodic filterbank. The detailed discussion is presented in Appendix A.1. Since we use inter-channel phase difference as sound source spatial location clue, we require the four microphones are configured close to each other (e.g. 4 cm distant with each other) because there are other inter-channel information to be considered like amplitude difference and energy decay if microphone array is distantly-configured (e.g. put microphones at a large house's different corners).",
        "evidence": "The fundamental task for an agent to perceive and interact with the 3D environment is to know the location and semantic identity of its nearby objects. The location includes spatial location that is either stationary or moving, temporal location like start time and end time. Vision-based such environment perception has received large attention in the past decade and we have witnessed huge progress in tasks such as object detection, classification and tracking. Nevertheless, the sound-based counterpart research has far lagged behind, despite all the fascinating properties sound signal exhibits. For example, sound is ubiquitous and insensitive to ambient illumination change, it has no field-of-view (FoV) constraints and is capable of circumventing physical barriers to perceive scene beyond line-of-sight. As a complementary sensing approach to vision, sound-based environment perception is of vital importance for acoustic scene understanding. A typical example is the sound source detection (answer where is it, when does it happen and what is it), given the recorded multi-channel sound waveforms.\nTo detect sound sources, we often deploy a spatially-configured microphone array to record an acoustic environment. Unlike camera or LiDAR scanner that directly captures RGB image or measures the range distance, sound waveform itself is a highly compressed one-dimensional points with high sampling rate, all sound source signals are compressed and mixed into the one-dimensional data format. Since different sound sources have different frequency property, it is essential convert waveform into time-frequency representation so that frequencies hidden in the waveform are explicitly split out. This is often achieved by projecting the raw waveform into various orthogonal frequency basis. At the same time, a sound source's spatial location clue lies in inter-channel difference of recorded waveforms (i.e. phase difference in this work). It is essential to design a neural network that jointly encodes mono-channel time-frequency representation and inter-channel phase difference from the raw waveforms in a unified, parameter-frugal and computation-efficient manner. The learned representation should have elegant resolution in both time, frequency and space domain so that sound sources can be precisely detected.\nHowever, learning such representation is a tough task. Challenges derive from both theoretical side and practical side. According to Uncertainty Principle, we cannot achieve the optimal resolution in time and frequency domain at the same time, but instead keep a trade-off between them. Traditional hand-engineered sound feature and some recently proposed learnable filter bank empirically set the same length for all filters, resulting in human-biased, unadjustable time-frequency resolution map. Some other work correlates filter frequency response and filter length by initializing in mel-scale, but it is not scalable nor stable because the final initialization depends on the filter number. Moreover, all existing methods process raw waveform with one-scale filter bank, we argue that the one-scale sound perception easily leads to incomprehensive sound sources sensing, especially when sound sources have different frequency property or undergo various spatial motion.\nIn this paper, we first give comprehensive theoretical analysis on the filter bank impact on its extracted feature's time and frequency resolution. Based on the analysis, we propose a simple yet effective synperiodic filter bank construction strategy in which each filter's frequency response and length are correlated by rotating periodicity such that each filter's length is inversely proportional to its frequency resolution. The synperiodic filter bank thus internally maintains a better time-frequency resolution trade-off than traditional fixed-length filter bank. Coupling the filter length with its frequency response helps us to reduce human intervention in filter bank design. By simply alternating the periodicity term, we further construct a group of synperiodic filter banks, with which we achieve multi-scale perception in time domain. At the same time, by applying a synperiodic filter bank to process one raw waveform as well as its consecutively-downsampled versions, we achieve multi-scale perception in frequency domain. The multi-scale perception in both time and frequency domain of synperiodic filter bank enables the neural network to dynamically learn better representation for sound source detection in a data-driven way. It is worth noting that synperiodic filter bank parameter number is just linear to filter number (adds up to less than 1% of the whole parameters) and it can be efficiently implemented as a 1D convolution operator.\nFollowing the aforementioned learnable front-end, we add a Transformer-like backbone network with two paralleling branches with intermediate soft-parameter sharing to learn sound source's semantic and spatial location related representation both jointly and separately. Experiment on both direction-of-arrival (DoA) task and physical location estimation task shows that our proposed framework outperforms comparing methods by a large margin. Replacing existing method's head with our proposed synperiodic filter bank also improvdes the performance.\nWe use a spatially-deployed microphone array, like four closely-bounded microphones in a circular coplanar configuration, to record an acoustic environment where various sound sources undergo independent and unconstrained spatial motion. Recorded multi-channel raw waveforms are represented as W \" tx i ptqu 4\ni\"1 , each waveform is 1-d vector of size T sampled at a fixed sampling rate. We denote K sound sources by S \" ts k \" pt k s , t k e , sp k , sl k qu K k\"1 , one single sound source corresponds to a start time t s , end time t e , stationary or moving spatial motion sp and a semantic identity label sl. Our goal is to learn a representation P that is representative enough to detect sound sources both spatially and semantically. P is a temporal framewise representation of shape T 1 ˆN . We propose to learn P directly from the raw waveforms via a deep neural network F parameterized by θ,\nA learned elegant representation should have large resolution in both time, frequency and space domain and exhibit strong capability at addressing three intrinsic challenges: Polyphonicity, sound sources are mutually independent, they can freely overlap temporally; Time-scale variance, the Figure: Synperiodic filter bank illustration: Syndistance filter bank (green color) rotates the same distance in complex plane and thus has the same kernel length, regardless of frequency it carries. Its time-frequency dynamic resolution map is thus rectangular. our proposed synperiodic filter bank (blue color) are generated by rotating the same periodicity number. So filter carrying lower frequency has larger kernel size than those with higher frequency response. As a result, synperiodic filter bank's time-frequency dynamic resolution map that is able to achieve a better trade-off than traditional syndistance filter bank.\ntemporal duration of different sound sources varies enormously, from seconds to minutes long; Datasize, sound waveform is sampled with large sampling rate, resulting in large data size.\nSound source presence clue lies in mono-channel time-frequency representation and its spatial motion clue lies in inter-channel interaction, like phase difference. Our proposed synperiodic filter bank group jointly encodes time-frequency representation and phase difference from raw waveforms in a unified way. More detail about phase difference encoding is given in the Appendix A.1.\nWe use the previously constructed synperiodic filter bank group to convolve with mono-channel sound waveform with the same step size and padding strategy, resulting in the same size output for each single synperiodic filter bank. Since different filter group has different window size, we naturally achieve multi-scale learning in time domain. It maximally avoids us empirically selecting one window scale ρ which might not be optimal, but instead uses a group of filter bank to enforce the neural network to strike a better time-frequency resolution trade-off in a data-driven way.\nWe further propose a strategy to enable multi-scale learning in frequency domain. The strategy is hierarchical: given a raw sound waveform with sampling frequency F S , synperiodic filter bank's frequency is initialized within the range r0, F S 2 s under Nyquist sampling theorem. If we downsample the sound waveform by a factor of 2, the resulting waveform can be processed by the lower-half Figure: Multi-scale learning in frequency domain. Given the raw one channel sound waveform and pre-constructed synperiodic filter bank, we consecutively downsample the waveform by factor 2x, the newly downsampled waveform is processed by low-half filter bank from the proceeding filter bank. We can obtain time-frequency representation for on each frequency scale. These timefrequency representations share the same time length by adjusting step size. The final time-frequency representation is obtained by max-pooling them together. filters in each group whose frequency response lies in r0, F S 4 s. This process that 2x-downsampling the waveform further process the downsampled waveform with filters with lower-half frequency response can potentially iterate a couple of times (in our case three times), resulting in multi-scale perception in frequency domain. The figurative illustration is shown by Fig.. Multi-scale learning in frequency domain brings us two extra benefits: 1) from data augmentation perspective, hierarchical 2x downsampling inevitably creates more waveforms, which matters a lot when labelling audio data is technically hard and time-consuming. 2) from the causality perspective, the adjacent 2xdownsampling strategy leads to dilated convolution for lower-frequency filters, because applying a filter to convolve with a downsampled waveform equals to convolve on the original waveform with dilated convolution (skip-2 connection). The resulting wider field of view (FoV) for lower frequency filters enables to learn better sound causality along the time axis (see Appendix A.4). In sum, by using learnable synperiodic filter bank group to process the raw waveform in multi-scale manner, we achieve a dynamic time-frequency resolution map that naturally maintains a better time-frequency resolution map fitting for sound source detection in a data-driven way.\nComputational Analysis Synperiodic filter bank group introduces very few parameters (less than 1%) because they are parameterized filters. The trainable parameter number increases linearly w.r.t. synperiodic filter bank number. Their convolution with raw waveforms can also be efficiently implemented with 1D convolution.\nSince different sound sources have different frequency property, it is essential convert waveform into time-frequency representation so that frequencies hidden in the waveform are explicitly split out. This is often achieved by projecting the raw waveform into various orthogonal frequency basis. At the same time, a sound source’s spatial location clue lies in inter-channel difference of recorded waveforms (i.e. phase difference in this work). It is essential to design a neural network that jointly encodes mono-channel time-frequency representation and inter-channel phase difference from the raw waveforms in a unified, parameter-frugal and computation-efficient manner.****Sound source presence clue lies in mono-channel time-frequency representation and its spatial motion clue lies in inter-channel interaction, like phase difference.

Adapting the unconstrained logits is easier than adapting the corresponding probabilities. We apologize that this was not clearly defined in the paper. We have now revised the paper with this definition in section 3.1.",
        "evidence": "Consider the Gaussian mixtures corresponding to the source and target channel conditional densities, where θ c and θ c are the parameter vectors of the original and adapted MDN. Here µ i (x) ∈ R d is the mean vector, σ 2 i (x) ∈ R d + is the variance vector, and π i (x) ∈ [0, 1] is the prior probability (weight) of component i for the original mixture. We have assumed that the Gaussian components have a diagonal covariance matrix, with σ 2 i (x) being the diagonal elements 2 . The mixture weights are parameterized using the softmax function as π i (x) = e αi(x) / k j=1 e αj (x) , ∀i. The MDN simply predicts the un-normalized weights α i (x) ∈ R or the prior logits. The parameter vector of component i is defined as Affine and Inverse-Affine Feature Transfomations. Applying the above result to our MDN with k components, we define the affine feature transformation for a given symbol x and component i,\n(3)\nIt is straightforward to also define the inverse-affine transformation from y to y as\nFor the case of diagonal covariances, we constrain C i to be diagonal. These feature transformations will be used for aligning the target and source class-conditional distributions of the decoder input.\nParameter Transformations. The corresponding transformations between the source and target Gaussian mixture parameters for any symbol x ∈ X and component i ∈ [k] are given by\nwhere\n) is a diagonal scale matrix for the variances; and β i ∈ R and γ i ∈ R are the scale and offset for the prior logits.\nThe vector of all adaptation parameters to be optimized is defined as\n, where ψ T i contains the affine-transformation parameters from component i. The number of adaptation parameters (dimension of ψ) is given by k (d 2 + 2 d + 2). This is typically much smaller than the number of MDN parameters (weights and biases from all layers), even for shallow fully-connected NNs. In Fig., the adaptation layer mapping φ(x) to φ(x) basically implements the parameter transformations defined in Eq. ().\nAssumptions and Key Insight. The proposed adaptation of the MDN is based on the affinetransformation property of multivariate Gaussians, i.e., one can transform between any two multivariate Gaussians through an affine transformation. Assumption 1: The source and target Gaussian mixtures have the same number of components. This is a practical assumption we make in order to not have to change the architecture of the MDN. Adding or removing components would require a change to the output layer of the MDN. Also, this assumption can be practically justified when k is chosen to be sufficiently large. Assumption 2: The two mixtures have a one-to-one correspondence between the components. This assumption makes in mathematically convenient to derive a closed-form expression for the KL-divergence between two Gaussian mixtures, which would not be possible in the general case.\nBased on the above assumptions, we can formulate the MDN adaptation as an equivalent problem of finding the optimal set of affine transformations (one per-component) from the source to the target Gaussian mixture. This is a much smaller problem compared to optimizing the weights of all the MDN layers. Moreover, the affine transformations are bijective, allowing the feature and parameter mapping to be applied in the inverse direction. To reduce the possibility of the adapted MDN finding bad solutions due to the small-sample regime, we include a regularization term based on the KL-divergence (KLD) in the adaptation objective.\nHere µi(x) ∈ R d is the mean vector, σ 2 i (x) ∈ R d + is the variance vector, and πi(x) ∈ [0, 1] is the prior probability (weight) of component i for the original mixture. We have assumed that the Gaussian components have a diagonal covariance matrix, with σ 2 i (x) being the diagonal elements 2 . The mixture weights are parameterized using the softmax function as πi(x) = e αi(x) / Pk j=1 e αj (x) , ∀i. The MDN simply predicts the un-normalized weights αi(x) ∈ R or the prior logits. The parameter vector of component i is defined as φi(x) T = [αi(x), µi(x) T ,σ 2 i (x) T ], and the MDN output φ(x) has dimension k (2d + 1). The adapted MDN predicts the parameters of the target Gaussian mixture φb(x) = Mθbc (x) as shown in Fig. 1. The parameters of the adapted MDN and Gaussian mixture are similarly defined, with a hat in the notation.",

It has attracted much attention recently as it could make texts more accessible to wider audiences, and used as a pre-processing step, improve performances of various NLP tasks and systems BIBREF13 , BIBREF14 , BIBREF15 . Usually, hand-crafted, supervised, and unsupervised methods based on resources like English Wikipedia and Simple English Wikipedia (EW-SEW) BIBREF10 are utilized for extracting simplification rules. It is very easy to mix up the automatic TS task and the automatic summarization task BIBREF3 , BIBREF16 , BIBREF6 . TS is different from text summarization as the focus of text summarization is to reduce the length and redundant content.\nAt the lexical level, lexical simplification systems often substitute difficult words using more common words, which only require a large corpus of regular text to obtain word embeddings to get words similar to the complex word BIBREF1 , BIBREF9 . Biran et al. BIBREF0 adopted an unsupervised method for learning pairs of complex and simpler synonyms from a corpus consisting of Wikipedia and Simple Wikipedia. At the sentence level, a sentence simplification model was proposed by tree transformation based on statistical machine translation (SMT) BIBREF3 . Woodsend and Lapata BIBREF17 presented a data-driven model based on a quasi-synchronous grammar, a formalism that can naturally capture structural mismatches and complex rewrite operations. Wubben et al. BIBREF18 proposed a phrase-based machine translation (PBMT) model that is trained on ordinary-simplified sentence pairs. Xu et al. BIBREF19 proposed a syntax-based machine translation model using simplification-specific objective functions and features to encourage simpler output.\nCompared with SMT, neural machine translation (NMT) has shown to produce state-of-the-art results BIBREF5 , BIBREF7 . The central approach of NMT is an encoder-decoder architecture implemented by recurrent neural networks, which can represent the input sequence as a vector, and then decode that vector into an output sequence. Therefore, NMT models were used for text simplification task, and achieved good results BIBREF8 , BIBREF4 , BIBREF20 . The main limitation of the aforementioned NMT models for text simplification depended on the parallel ordinary-simplified sentence pairs. Because ordinary-simplified sentence pairs are expensive and time-consuming to build, the available largest data is EW-SEW that only have 296,402 sentence pairs. The dataset is insufficiency for NMT model if we want to NMT model can obtain the best parameters.

        "evidence": "It is common knowledge in modern NLP that using large amounts of high-quality training data is a key aspect in building successful machine-learning based systems. For this reason, a major challenge when building such systems is obtaining data in the domain of interest. But what defines a domain? Natural language varies greatly across topics, styles, levels of formality, genres and many other linguistic nuances BIBREF0, BIBREF1, BIBREF2. This overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impossible to well-define the exact requirements from such data with respect to all the aforementioned aspects. On top of that, domain labels are usually unavailable – e.g. in large-scale web-crawled data like Common Crawl which was recently used to train state-of-the-art pretrained language models for various tasks BIBREF3.\nDomain data selection is the task of selecting the most appropriate data for a domain from a large corpus given a smaller set of in-domain data BIBREF4, BIBREF5, BIBREF6, BIBREF7. In this work, we propose to use the recent, highly successful self-supervised pre-trained language models, e.g. devlin-etal-2019-bert,liu2019roberta for domain data selection. As pretrained LMs demonstrate state-of-the-art performance across many NLP tasks after being trained on massive amounts of data, we hypothesize that the robust representations they learn can be useful for mapping sentences to domains in an unsupervised, data-driven approach. We show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering. We then propose methods to leverage these emergent domain clusters for domain data selection in two ways:\nVia distance-based retrieval in the sentence embedding space induced by the pretrained language model.\nBy fine-tuning the pretrained language model for binary classification, where positive examples are from the domain of interest.\nOur methods enable to select relevant data for the task while requiring only a small set of monolingual in-domain data. As they are based solely on the representations learned by self-supervised LMs, they do not require additional domain labels which are usually vague and over-simplify the notion of domain in textual data. We evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8. Our data selection methods enable to train NMT models that outperform those trained using the well-established cross-entropy difference method of BIBREF4 across five diverse domains, achieving a recall of more than 95% in all cases with respect to an oracle that selects the “true” in-domain data.\nOur contributions in this work are as follows. First, we show that pre-trained language models are highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner. Second, we propose methods to select in-domain data based on this property using vector-space retrieval and positive-unlabeled fine-tuning of pretrained language models for binary classification. Third, we show the applicability of our proposed data selection methods on a popular benchmark for domain adaptation in machine translation. An additional contribution is a new, improved data split we create for this benchmark, as we point on issues with previous splits used in the literature. The code and data for this work is publicly available. We hope this work will encourage more research on understanding the data landscape in NLP, enabling to “find the right data for the task” in the age of massive models and diverse data sources.\nWe show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering.",

        "evidence": "The advent of smart agents such as Amazon Echo and Google Home has shown relatively wide market adoption. Users have been familiarized with formulating questions and orders in a way that these agents can easily comprehend and take actions. Given this trend, particularly for cases where questions can have various forms such as yes/no, alternative, wh-, echo and embedded BIBREF0, a number of analysis techniques have been studied in the domain of semantic role labeling BIBREF1 and entity recognition BIBREF2. Nowadays, various question answering tasks have been proposed BIBREF3 and have yielded systems that have demonstrated significant advances in performance. Studies on the parsing of canonical imperatives BIBREF4 have also been done for many household agents.\nHowever, discerning the intent from a conversational and non-canonical sentence (question or command) and extracting its intent argument is still a challenge. Additional complexity is introduced when the target text is in a speech recognition context, as the result may not contain punctuation. For example, given an unclear declarative question BIBREF5 such as “poppa joe you want me to go now”, a human listener can interpret the question as `if Joe wants the speaker to go now', but this can be challenging to for a machine. Also, sometimes, merely the speech act can be hard to guess from the sentence form, as in inferring “why don't you just call the police” as a representation of the to-do list `to call the police' (Figure 1). Although many advanced dialog managing systems may generate a plausible reaction to the input utterances, it is different from extracting the exact intent argument (a question set or a to-do-list) that should be investigated for an actual operation.\nComplexities like the example discussed above have not seen much exploration outside of English, especially in the context of languages with a distinguished syntax or cases which do not use Latin-like alphabets. As a more concrete example, in the Korean language, the morphology is agglutinative, the syntax is head-final, and scrambling (non-deterministic permutations of word/phrase ordering) is a common practice between native speakers. Specifically, the agglutinative property of Korean requires additional morphological analysis, which makes it challenging to identify the component of the sentence that has the strongest connection to core intent. Additionally, the head-finality characteristic introduces an additional layer of complexity, where an under-specified sentence ender incorporates a prosodic cue which requires disambiguation to comprehend the original intent BIBREF6, BIBREF7. Finally, considering the scrambling aspect, which frequently happens in spoken utterances, further analysis is required on top of recognizing the entities and extracting the relevant phrases. This makes it difficult for dialog managers to directly apply conventional analysis methods that have been used in Germanic or other Indo-European languages.\nIn this paper, we explore these aspects in the context of Korean, a less explored, low-resource language with various non-canonical expressions. From there on, we propose a structured sentence annotation scheme which can help enrich the human-like conversation with artificial intelligence (AI). For the automation, we annotate an existing corpus and then augment the dataset to mitigate class imbalance, demonstrating the flexibility, practicality, and extensibility of the proposed methods. To further prove that the scheme is not limited to Korean, we demonstrate the methodology using English examples and supplement specific cases with Korean. To begin with, in section 2, we present the theoretical background of this study. We then discuss the detailed procedure with examples, along with an explanation of how it fits with modern natural language understanding (NLU) systems and an evaluation framework.\nFor the automation, we annotate an existing corpus and then augment the dataset to mitigate class imbalance, demonstrating the flexibility, practicality, and extensibility of the proposed methods.",

Only move backwards when you consistently shoot a high percentage  of made shots.  Finally, you want to focus with movement without the ball.

        "answer": "Ammanabrolu & Hausknecht.",
        "evidence": "Many reinforcement learning algorithms are designed for relatively small discrete or continuous action spaces and so have trouble scaling. Text-adventure games—or interaction fictions—are simulations in which both an agents' state and action spaces are in textual natural language. An example of a one turn agent interaction in the popular text-game Zork1 can be seen in Fig. FIGREF1. Text-adventure games provide us with multiple challenges in the form of partial observability, commonsense reasoning, and a combinatorially-sized state-action space. Text-adventure games are structured as long puzzles or quests, interspersed with bottlenecks. The quests can usually be completed through multiple branching paths. However, games can also feature one or more bottlenecks. Bottlenecks are areas that an agent must pass through in order to progress to the next section of the game regardless of what path the agent has taken to complete that section of the quest BIBREF0. In this work, we focus on more effectively exploring this space and surpassing these bottlenecks—building on prior work that focuses on tackling the other problems.\nFormally, we use the definition of text-adventure games as seen in BIBREF1 and BIBREF2. These games are partially observable Markov decision processes (POMDPs), represented as a 7-tuple of $\\langle S,T,A,\\Omega , O,R, \\gamma \\rangle $ representing the set of environment states, mostly deterministic conditional transition probabilities between states, the vocabulary or words used to compose text commands, observations returned by the game, observation conditional probabilities, reward function, and the discount factor respectively. For our purposes, understanding the exact state and action spaces we use in this work is critical and so we define each of these in relative depth.\nAction-Space. To solve Zork1, the cannonical text-adventure games, requires the generation of actions consisting of up to five-words from a relatively modest vocabulary of 697 words recognized by the game’s parser. This results in $\\mathcal {O}(697^5)={1.64e14}$ possible actions at every step. To facilitate text-adventure game playing, BIBREF2 introduce Jericho, a framework for interacting with text-games. They propose a template-based action space in which the agent first selects a template, consisting of an action verb and preposition, and then filling that in with relevant entities $($e.g. $[get]$ $ [from] $ $)$. Zork1 has 237 templates, each with up to two blanks, yielding a template-action space of size $\\mathcal {O}(237 \\times 697^2)={1.15e8}$. This space is still far larger than most used by previous approaches applying reinforcement learning to text-based games.\nState-Representation. Prior work has shown that knowledge graphs are effective in terms of dealing with the challenges of partial observability $($BIBREF3 BIBREF3; BIBREF4$)$. A knowledge graph is a set of 3-tuples of the form $\\langle subject, relation, object \\rangle $. These triples are extracted from the observations using Stanford's Open Information Extraction (OpenIE) BIBREF5. Human-made text-adventure games often contain relatively complex semi-structured information that OpenIE is not designed to parse and so they add additional rules to ensure that the correct information is parsed. The graph itself is more or less a map of the world, with information about objects' affordances and attributes linked to the rooms that they are place in a map. The graph also makes a distinction with respect to items that are in the agent's possession or in their immediate surrounding environment. An example of what the knowledge graph looks like and specific implementation details can be found in Appendix SECREF14.\nBIBREF6 introduce the KG-A2C, which uses a knowledge graph based state-representation to aid in the section of actions in a combinatorially-sized action-space—specifically they use the knowledge graph to constrain the kinds of entities that can be filled in the blanks in the template action-space. They test their approach on Zork1, showing the combination of the knowledge graph and template action selection resulted in improvements over existing methods. They note that their approach reaches a score of 40 which corresponds to a bottleneck in Zork1 where the player is eaten by a “grue” (resulting in negative reward) if the player has not first lit a lamp. The lamp must be lit many steps after first being encountered, in a different section of the game; this action is necessary to continue exploring but doesn’t immediately produce any positive reward. That is, there is a long term dependency between actions that is not immediately rewarded, as seen in Figure FIGREF1. Others using artificially constrained action spaces also report an inability to pass through this bottleneck BIBREF7, BIBREF8. They pose a significant challenge for these methods because the agent does not see the correct action sequence to pass the bottleneck enough times. This is in part due to the fact that for that sequence to be reinforced, the agent needs to reach the next possible reward beyond the bottleneck.\nMore efficient exploration strategies are required to pass bottlenecks. Our contributions are two-fold. We first introduce a method that detects bottlenecks in text-games using the overall reward gained and the knowledge graph state. This method freezes the policy used to reach the bottleneck and restarts the training from there on out, additionally conducting a backtracking search to ensure that a sub-optimal policy has not been frozen. The second contribution explore how to leverage knowledge graphs to improve existing exploration algorithms for dealing with combinatorial action-spaces such as Go-Explore BIBREF9. We additionally present a comparative ablation study analyzing the performance of these methods on the popular text-game Zork1.\nAmmanabrolu & Hausknecht (2020) introduce the KG-A2C,2 which uses a knowledge graph based state-representation to aid in the section of actions in a combinatorially-sized action-space— specifically they use the knowledge graph to constrain the kinds of entities that can be filled in the blanks in the template action-space.",

In our proposed rolled graph representation, the nodes are defined to represent filters in convolutional layers; on the other hand, the nodes represent feature maps in the unrolled representation introduced by (Rieck et al, 2019). Thus, we argue that it is easier to interpret the outputs of downstream graph analysis on our graph representation (e.g., computing node properties, tracking the evolution of the graph, performing community detection). For example, when we calculate the eigenvector centrality, it is clear which filters (from a specific layer) are the most influential filters; if we were to do the same calculation on the previously introduced unrolled representation, it would not be possible to draw such a conclusion. Furthemore, we believe that our graph representation can be a powerful tool for future studies that aim to understand the NN dynamics.",
        "evidence": "Overview & Motivation. To preserve the semantic meaning of conv layers, we represent each filter as a node, and link filters in consecutive layers via weighted edges (we define the weights below), as shown in Fig.. The motivation behind this approach is that for larger networks, there is an explosion of nodes by unrolling the convolutions (unrolled representation explained in § 2.3), and the integrity of a unit (a single filter or kernel) becomes untenable. Also, by mapping the nodes to specific entities of NNs, our proposed graph model is more interpretable than the unrolled model, and thus it is easier to interpret the outputs of downstream graph analysis on our graph representation (e.g., computing node features, tracking the evolution of the graph).\nDetailed Description. Formally, let tensor K i be a kernel in layer i with f i filters, each with c i channels and dimensions h i ×w i . We use bracket notation to index into the kernel: for example, K i [l, : , :, :] indexes the l th filter of kernel K i . We create f i nodes representing each filter {v\nfi }, with features defined as the corresponding biases in that layer. Let K j be the next convolutional layer defined analogously. While edge weights between neurons in FC layers are defined in the standard way, we define the edge weights between conv layers as the norm over each kernel's channels. The edge between node v (i) k representing the k th filter in layer i (i.e., K i [k, :, :, :]) and node/filter v\nwhich is the norm of the k th channel of the l th filter in the j th layer. Though the proposed representations enable alternative edge weight configurations, we focus on the norm of filters as other studies, including those on pruning NNs, have demonstrated that this metric has strong correlation with filter importance. In the case of two conv layers, the resultant graph is an attributed bipartite graph with f i + f j nodes and f i × f j edges, where node attributes include flattened weight vectors or filter maps. Other information such as average gradients or the bias vector can also be used for node features.\nWe cover the most relevant work here, and dynamic graph mining in App. A.5.

A diagram of our system is shown in Figure FIGREF4 .\nThe idea behind this modification is to provide the encoder with access to all morpho-syntactic cues present in the sentence. In contrast to the baseline, which only encodes the immediately adjacent context of a target word, we encode the entire context. All context word forms, lemmas, and MSD tags (in Track 1) are embedded in their respective high-dimensional spaces as before, and their embeddings are concatenated. However, we now reduce the entire past context to a fixed-size vector by encoding it with a forward LSTM, and we similarly represent the future context by encoding it with a backwards LSTM.\nWe introduce an auxiliary objective that is meant to increase the morpho-syntactic awareness of the encoder and to regularise the learning process—the task is to predict the MSD tag of the target form. MSD tag predictions are conditioned on the context encoding, as described in UID15 . Tags are generated with an LSTM one component at a time, e.g. the tag PRO;NOM;SG;1 is predicted as a sequence of four components, INLINEFORM0 PRO, NOM, SG, 1 INLINEFORM1 .\nFor every training instance, we backpropagate the sum of the main loss and the auxiliary loss without any weighting.\nAs MSD tags are only available in Track 1, this augmentation only applies to this track.\nThe parameters of the entire MSD (auxiliary-task) decoder are shared across languages.\nSince a grouping of the languages based on language family would have left several languages in single-member groups (e.g. Russian is the sole representative of the Slavic family), we experiment with random groupings of two to three languages. Multilingual training is performed by randomly alternating between languages for every new minibatch. We do not pass any information to the auxiliary decoder as to the source language of the signal it is receiving, as we assume abstract morpho-syntactic features are shared across languages.\nAfter 20 epochs of multilingual training, we perform 5 epochs of monolingual finetuning for each language. For this phase, we reduce the learning rate to a tenth of the original learning rate, i.e. 0.0001, to ensure that the models are indeed being finetuned rather than retrained.\nWe keep all hyperparameters the same as in the baseline. Training data is split 90:10 for training and validation. We train our models for 50 epochs, adding early stopping with a tolerance of five epochs of no improvement in the validation loss. We do not subsample from the training data.\nWe train models for 50 different random combinations of two to three languages in Track 1, and 50 monolingual models for each language in Track 2. Instead of picking the single model that performs best on the development set and thus risking to select a model that highly overfits that data, we use an ensemble of the five best models, and make the final prediction for a given target form with a majority vote over the five predictions.\nTraining data is split 90:10 for training and validation.",

        "question": "What are the different types of loan or mortgage products for home buyers in the U.S.?",
        "evidence": "",
        "answer": "It is crucial to understand all your financing options when considering buying a new home. Some of the most common loan types for residential home buyers are listed below:\n\n1. Conventional Loans: The most common home loan type that is not insured or guaranteed by the government. While it typically requires 20% down payment, you can put as little as 5% down.\n2. VA Loans: This is offered by the U.S. Department of Veterans Affairs for people who have served in the military as well as their spouses. It requires no down payment and is an amazing option for anyone who is eligible.\n3. FHA Loan: A mortgage insured by the Federal Housing Administration. First time home buyers find these loans very attractive due to the small down payment requirements of just 3.5% and the flexible credit requirements. Additionally there are children products to this loan vehicle including the FHA 203k loan which can help those purchasing distressed properties by funding the renovations, within certain predetermined guidelines.\n4. Adjustable-Rate Mortgage (ARM): With this product, your interest rate varies over time depending on market and economic conditions. These seem attractive initially as they typically start with lower rates than fixed-rate mortgages but can increase over time.\n5. Fixed-Rate Mortgages: This interest rate is locked in at the start of the loan and starts the same throughout the entire term.\n7. USDA Loan: Guaranteed by the U.S. Department of Agriculture and eligible to suburban and rural homebuyers. This loan product also doesn't require down payment and has lower mortgage insurance requirements than an FHA loan\n\nWhile these are the most common loan types, other options tend to appear from time to time. It is important to do your research and pick the product that best suits your individual needs and long-term financial goals. To help better understand these options many aspiring buyers reach out to local loan providers, real estate agents, and brokers.",

        "evidence": "Byte pair encoding (BPE) or digram coding is a simple and robust form of data compression in which the most common pair of contiguous bytes of data in a sequence are replaced with a byte that does not occur within the sequence. A lookup table of the replacements is required to rebuild the original data. The algorithm was first described publicly by Philip Gage in a February 1994 article \"A New Algorithm for Data Compression\" in the C Users Journal.\n\nA variant of the technique has shown to be useful in several natural language processing (NLP) domains, for applications such as tokenisation, as seen in Google's SentencePiece and OpenAI's GPT-3. Here, the goal is not data compression, but tokenisation of text in a given language to produce a variable sequence of terms from a fixed-size vocabulary of tokens. Typically, most words will be encoded as a single token, while rare words will be encoded as a sequence of a few tokens, where these tokens represent meaningful word parts. This translation of text into tokens can be found by variants of byte pair encoding, such as subword units.\n\nByte pair encoding lends itself to NLP tasks due to its simplicity and speed; BPE is suitably effective for the tokenisation of terms, does not require large computational overheads, and remains consistent, making it reliable.",

        "question": "Is Python or Java a better programming language?",
        "evidence": "",
        "answer": "Python and Java are two of the most popular and robust programming languages.  Java is the fifth most commonly used programming language according to Stack Overflow. Java is generally faster and more efficient than Python because it is a compiled language. While it's one of the coding languages considered to be easy to learn because many of the processes of this high-level language run automatically. However, Python still takes the cake in terms of simplicity. \n\n As an interpreted language, Python has simpler, more concise syntax than Java. It can perform the same function as Java in fewer lines of code. Python also offers extensive libraries, especially around data analysis and machine learning. Because it's dynamically typed, it allows for even fast development compared to Java. \n\nOther key differences include how each handles memory management and the ability to run multiple threads at the same time. \n\nFor example, lets dive into this threading difference. Java fully supports multithreading. When you use Java, you can run more than one thread at a time. When running multiple threads, they share a common memory area to increase efficiency and performance. Now if you search the web for threading in Python you might be a bit confused. You will find articles claiming that Python can't support multithreading but then you will also find tutorials and packages for threading and parallel processing. Python has a Global Interpreter Lock that only lets one thread execute at a time, so if you're working on a multi-threaded CPU-bound program, it'll likely be even slower. However, it's threading package allows you to speed up I/O bound programs. Using multiprocessing programs instead of multithreaded programs can be an effective workaround.\n\nThe answer to which is better is largely dependent on the user and the use case. Before learning one or starting a new project with either, think about what your goals are and decide which one fits those more closely.",

        "answer": "Although they are successful in the low-resource scene, they have limited effects in zero-shot translation.",
        "evidence": "In recent years, zero-shot translation in NMT has attracted widespread attention in academic research. Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.\nPivot-based Method is a common strategy to obtain a source$\\rightarrow $target model by introducing a pivot language. This approach is further divided into pivoting and pivot-synthetic. While the former firstly translates a source language into the pivot language which is later translated to the target language BIBREF4, BIBREF5, BIBREF12, the latter trains a source$\\rightarrow $target model with pseudo data generated from source-pivot or pivot-target parallel data BIBREF13, BIBREF14. Although the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter-vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation problem BIBREF15.\nTransfer Learning is firstly introduced for NMT by BIBREF6, which leverages a high-resource parent model to initialize the low-resource child model. On this basis, BIBREF7 and BIBREF8 use shared vocabularies for source/target language to improve transfer learning, while BIBREF16 relieve the vocabulary mismatch by mainly using cross-lingual word embedding. Although these methods are successful in the low-resource scene, they have limited effects in zero-shot translation.\nMultilingual NMT (MNMT) enables training a single model that supports translation from multiple source languages into multiple target languages, even those unseen language pairs BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21. Aside from simpler deployment, MNMT benefits from transfer learning where low-resource language pairs are trained together with high-resource ones. However, BIBREF22 point out that MNMT for zero-shot translation easily fails, and is sensitive to the hyper-parameter setting. Also, MNMT usually performs worse than the pivot-based method in zero-shot translation setting BIBREF23.\nUnsupervised NMT (UNMT) considers a harder setting, in which only large-scale monolingual corpora are available for training. Recently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training BIBREF24, BIBREF25, BIBREF26, BIBREF11. Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.\nOur proposed method belongs to the transfer learning, but it is different from traditional transfer methods which train a parent model as starting point. Before training a parent model, our approach fully leverages cross-lingual pre-training methods to make all source languages share the same feature space and thus enables a smooth transition for zero-shot translation.\nTransfer Learning is firstly introduced for NMT by Zoph et al. (2016), which leverages a high-resource parent model to initialize the low-resource child model. On this basis, Nguyen and Chiang (2017) and Kocmi and Bojar (2018) use shared vocabularies for source/target language to improve transfer learning, while Kim, Gao, and Ney (2019) relieve the vocabulary mismatch by mainly using cross-lingual word embedding.

Here are some steps to follow to help you get out of a maze:\n\nStay Calm and Focused: Getting lost in a maze can be frustrating, but it's important to stay calm and focused. Take deep breaths, relax, and clear your mind. This will help you to think more clearly and make better decisions.\n\nPlan Your Route: Take a few minutes to look at the maze from above, if possible, and try to identify the route to the exit. Identify landmarks or walls that you can use as reference points. Look for any dead ends, and try to avoid them.\n\nFollow One Wall: If you can't identify the exit route, try to follow one wall of the maze. Keep your hand on the wall and follow it all the way around the maze. This will help you to stay on track and avoid getting lost in circles.\n\nMark Your Path: If you have something to mark your path, such as chalk, breadcrumbs, or a pen, use it to mark your route as you go. This way, you can avoid taking the same path multiple times and can backtrack if necessary.\n\nLook for Clues: Keep an eye out for clues that may help you find your way out, such as arrows or signs. Many mazes also have hidden clues or puzzles that can help you find the exit, so keep your eyes open.\n\nAsk for Help: If you're still struggling to find your way out, don't be afraid to ask for help. Many mazes have staff members who can guide you out or provide you with clues.\n\nWith these tips in mind, you should be able to find your way out of a maze.

However, the legitimacy of this framework depends upon users actually reading and understanding privacy policies to determine whether company practices are acceptable to them BIBREF3. In practice this is seldom the case BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10. This is further complicated by the highly individual and nuanced compromises that users are willing to make with their data BIBREF11, discouraging a `one-size-fits-all' approach to notice of data practices in privacy documents.\nWith devices constantly monitoring our environment, including our personal space and our bodies, lack of awareness of how our data is being used easily leads to problematic situations where users are outraged by information misuse, but companies insist that users have consented. The discovery of increasingly egregious uses of data by companies, such as the scandals involving Facebook and Cambridge Analytica BIBREF12, have further brought public attention to the privacy concerns of the internet and ubiquitous computing. This makes privacy a well-motivated application domain for NLP researchers, where advances in enabling users to quickly identify the privacy issues most salient to them can potentially have large real-world impact.\n[1]https://play.google.com/store/apps/details?id=com.gotokeep.keep.intl [2]https://play.google.com/store/apps/details?id=com.viber.voip [3]A question might not have any supporting evidence for an answer within the privacy policy.\nMotivated by this need, we contribute PrivacyQA, a corpus consisting of 1750 questions about the contents of privacy policies, paired with over 3500 expert annotations. The goal of this effort is to kickstart the development of question-answering methods for this domain, to address the (unrealistic) expectation that a large population should be reading many policies per day. In doing so, we identify several understudied challenges to our ability to answer these questions, with broad implications for systems seeking to serve users' information-seeking intent. By releasing this resource, we hope to provide an impetus to develop systems capable of language understanding in this increasingly important domain.\nWe adopt a personalized approach to understanding privacy policies, that allows users to query a document and selectively explore content salient to them.",

The dough is made with four cups of flour, three tablespoons olive oil, a cup and a half of water, one package of yeast, a tablespoon of sugar, and a teaspoon and a half of salt. I typically activate the yeast in lukewarm water and sugar first, then mix all the ingredients in a stand mixer with a dough attachment. I'll add additional water until the dough is very wet, let it rise once in the mixing bowl, then turn the dough out on a surface coated generously with flour. Then I quarter the dough, fold a few times, and let rise again. \n\nForming the pies is the tricky part. I've found pushing the dough into a rough circle with my fingers as a first step works well, but he dough will tend to snap back. I'll pick up the small dough circle and stretch it out on top of my fists to start to break the gluten and form a larger pie with a thinner base. I use an Ooni oven pre-heated on high, but turn the heat down when I'm ready to put the pizza in. The peel needs to be generously coated with flour to get a good launch into the oven. After a few seconds, the dough on the bottom will cook enough that manipulating the pizza becomes much easier. I keep the toppings simple, mozzarella (low moisture), tomato sauce, basil. \n\nEnjoy!",

        "answer": "A black-box hyperparameter optimisation technique.",
        "evidence": "The scientific process by which the deep learning research community operates is guided by empirical studies that evaluate the relative quality of models. Complicating matters, the measured performance of a model depends not only on its architecture (and data), but it can strongly depend on hyperparameter values that affect learning, regularisation, and capacity. This hyperparameter dependence is an often inadequately controlled source of variation in experiments, which creates a risk that empirically unsound claims will be reported.\nIn this paper, we use a black-box hyperparameter optimisation technique to control for hyperparameter effects while comparing the relative performance of language modelling architectures based on LSTMs, Recurrent Highway Networks BIBREF0 and NAS BIBREF1 . We specify flexible, parameterised model families with the ability to adjust embedding and recurrent cell sizes for a given parameter budget and with fine grain control over regularisation and learning hyperparameters.\nOnce hyperparameters have been properly controlled for, we find that LSTMs outperform the more recent models, contra the published claims. Our result is therefore a demonstration that replication failures can happen due to poorly controlled hyperparameter variation, and this paper joins other recent papers in warning of the under-acknowledged existence of replication failure in deep learning BIBREF2 , BIBREF3 . However, we do show that careful controls are possible, albeit at considerable computational cost.\nSeveral remarks can be made in light of these results. First, as (conditional) language models serve as the central building block of many tasks, including machine translation, there is little reason to expect that the problem of unreliable evaluation is unique to the tasks discussed here. However, in machine translation, carefully controlling for hyperparameter effects would be substantially more expensive because standard datasets are much larger. Second, the research community should strive for more consensus about appropriate experimental methodology that balances costs of careful experimentation with the risks associated with false claims. Finally, more attention should be paid to hyperparameter sensitivity. Models that introduce many new hyperparameters or which perform well only in narrow ranges of hyperparameter settings should be identified as such as part of standard publication practice.\nIn this paper, we use a black-box hyperparameter optimisation technique to control for hyperparameter effects while comparing the relative performance of language modelling architectures based on LSTMs, Recurrent Highway Networks and NAS.",

        "answer": "Yes, it is.",
        "evidence": "Spoken dialogue systems, or conversational systems, are designed to interact and assist users using speech and natural language to achieve a certain goal BIBREF0. A consolidated approach to build a task-oriented dialogue system involves a pipeline architecture (see Figure FIGREF1), where each component is trained to perform a sub-task, and the combination of the modules in a given sequence aims at handling the complete task-oriented dialogue. In such a pipeline, a spoken language understanding (SLU) module determines the user's intent and the relevant information that the user is providing represented in terms of slot-value pairs. Then, the dialogue state tracker (DST) uses the information of the SLU together with the past dialogue context and updates its belief state BIBREF1, BIBREF2. In this framework a dialogue state indicates what the user requires at any point in the dialogue, and it is represented as a probability distribution over the possible states (typically a set of pre-defined slot-value pairs specific of the task). The dialogue policy manager, then, decides on the next system action based on the dialogue state. Finally, a natural language generation (NLG) component is responsible for the generation of an utterance that is returned as response to the user.\nIn this paper we focus on the dialogue state tracker component, whose role is to track the state of the dialogue based on the current user utterance, the conversation history and any additional information available to the system BIBREF0. Deep neural network techniques, such as recurrent neural network and convolutional neural networks, are the current state-of-the-art models for DST BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, showing high capacity to generalize from annotated dialogues. As an example, the GLAD model (Global-Locally Self-Attentive Dialogue State Tracker - BIBREF8), employs independent slot-specific encoders, consisting of a recurrent and a self-attention layer, for each of the user utterance, the system action and the slot-value pairs. Another DST system, GCE (Globally Conditioned Encoder - BIBREF9), simplifies the GLAD neural architecture removing the slot-specific recurrent and self-attention layers of the encoder, but still requires separate encoders for the utterance, the system action and the slot-values.\nAlthough the neural network models mentioned above achieve state-of-the-art performance, the complexity of their architectures make them highly inefficient in terms of time complexity, with a significant latency in their prediction time. Such latency may soon become a serious limitation for their deployment into concrete application scenarios with increasing number of slots, where real time is a strong requirement. Along this perspective, this work investigates the time complexity of state-of-the-art DST models and addresses their current limitations. Our contributions are the following:\nwe have designed and implemented an efficient DST, consisting of a Global encoder and Slot-Attentive decoders (G-SAT);\nwe provide empirical evidences (three languages of the WOZ2.0 dataset BIBREF6) that the proposed G-SAT model considerably reduces the latency time with respect to state-of-art DST systems (i.e. over 15 times faster), while keeping the dialogue state prediction inline with such systems;\nfurther experiments show that the proposed model is highly robust when either pre-trained embeddings are used or when they are not used, in this case outperforming state-of-art systems.\nThe implementation of the proposed G-SAT model is publicly available.\nThe paper is structured as follows. Section 2 summarizes the main concepts behind the definition of dialogue state tracking. Section 3 reports the relevant related work. Section 4 provides the details of the proposed G-SAT neural model, and, finally, Section 5 and 6 focus on the experiments and the discussion of the results we achieved.\nOur contributions are the following: we have designed and implemented an efficient DST, consisting of a Global encoder and Slot-Attentive decoders (G-SAT); we provide empirical evidences (three languages of the WOZ2.0 dataset) that the proposed G-SAT model considerably reduces the latency time with respect to state-of-art DST systems (i.e. over 15 times faster), while keeping the dialogue state prediction inline with such systems; further experiments show that the proposed model is highly robust when either pre-trained embeddings are used or when they are not used, in this case outperforming state-of-art systems.",

        "answer": "Use word alignments between sentences in a parallel corpus.",
        "evidence": "The multilingual model uses word alignments between sentences in a parallel corpus to exploit role correspondences across languages. We make copies of the monolingual model for each language and add additional crosslingual latent variables (CLVs) to couple the monolingual models, capturing crosslingual semantic role patterns. Concretely, when training on parallel sentences, whenever the head words of the arguments are aligned, we add a CLV as a parent of the two corresponding role variables. Figure FIGREF16 illustrates this model. The generative process, as explained below, remains the same as the monolingual model for the most part, with the exception of aligned roles which are now generated by both the monolingual process as well as the CLV.\nEvery predicate-tuple has its own inventory of CLVs specific to that tuple. Each CLV INLINEFORM0 is a multi-valued variable where each value defines a distribution over role labels for each language (denoted by INLINEFORM1 above). These distributions over labels are trained to be peaky, so that each value INLINEFORM2 for a CLV represents a correlation between the labels that INLINEFORM3 predicts in the two languages. For example, a value INLINEFORM4 for the CLV INLINEFORM5 might give high probabilities to INLINEFORM6 and INLINEFORM7 in language 1, and to INLINEFORM8 in language 2. If INLINEFORM9 is the only value for INLINEFORM10 that gives high probability to INLINEFORM11 in language 1, and the monolingual model in language 1 decides to assign INLINEFORM12 to the role for INLINEFORM13 , then INLINEFORM14 will predict INLINEFORM15 in language 2, with high probability. We generate the CLVs via a Chinese Restaurant Process BIBREF11 , a non-parametric Bayesian model, which allows us to induce the number of CLVs for every predicate-tuple from the data. We continue to train on the non-parallel sentences using the respective monolingual models.\nThe multilingual model is deficient, since the aligned roles are being generated twice. Ideally, we would like to add the CLV as additional conditioning variables in the monolingual models. The new joint probability can be written as equation UID11 (Figure FIGREF7 ), which can be further decomposed following the decomposition of the monolingual model in Figure FIGREF7 . However, having this additional conditioning variable breaks the Dirichlet-multinomial conjugacy, which makes it intractable to marginalize out the parameters during inference. Hence, we use an approximation where we treat each of the aligned roles as being generated twice, once by the monolingual model and once by the corresponding CLV (equation ).\nThis is the first work to incorporate the coupling of aligned arguments directly in a Bayesian SRL model. This makes it easier to see how to extend this model in a principled way to incorporate additional sources of information. First, the model scales gracefully to more than two languages. If there are a total of INLINEFORM0 languages, and there is an aligned argument in INLINEFORM1 of them, the multilingual latent variable is connected to only those INLINEFORM2 aligned arguments.\nSecond, having one joint Bayesian model allows us to use the same model in various semi-supervised learning settings, just by fixing the annotated variables during training. Section SECREF29 evaluates a setting where we have some labeled data in one language (called source), while no labeled data in the second language (called target). Note that this is different from a classic annotation projection setting (e.g. BIBREF12 ), where the role labels are mapped from source constituents to aligned target constituents.\nThe multilingual model uses word alignments between sentences in a parallel corpus to exploit role correspondences across languages.",

First, our AGDT utilizes an aspect-guided encoder, which leverages the given aspect to guide the sentence encoding from scratch and generates the aspect-guided representation. Second, the AGDT guarantees that the aspect-specific information has been fully embedded in the sentence representation via reconstructing the given aspect. Third, the given aspect embedding is concatenated on the aspect-guided sentence representation for final predictions.\nThe “HDS”, which is designed to measure whether a model can detect different sentiment polarities in a sentence, consists of replicated sentences with different sentiments towards multiple aspects. Our AGDT surpasses GCAE by a very large margin (+11.4% and +4.9% respectively) on both datasets. This indicates that the given aspect information is very pivotal to the accurate sentiment prediction, especially when the sentence has different sentiment labels, which is consistent with existing work BIBREF2, BIBREF3, BIBREF4. Those results demonstrate the effectiveness of our model and suggest that our AGDT has better ability to distinguish the different sentiments of multiple aspects compared to GCAE.\nExperiments ::: Main Results and Analysis ::: Aspect-Term Sentiment Analysis Task\nIn the “HDS” part, the AGDT model obtains +3.6% higher accuracy than GCAE on the restaurant domain and +4.2% higher accuracy on the laptop domain, which shows that our AGDT has stronger ability for the multi-sentiment problem against GCAE.

        "evidence": "Bernoulli's principle is a key concept in fluid dynamics that relates pressure, speed and height. Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.  The principle is named after the Swiss mathematician and physicist Daniel Bernoulli, who published it in his book Hydrodynamica in 1738.Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler in 1752 who derived Bernoulli's equation in its usual form. The principle is only applicable for isentropic flows: when the effects of irreversible processes (like turbulence) and non-adiabatic processes (e.g. thermal radiation) are small and can be neglected.\nBernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same at all points that are free of viscous forces. This requires that the sum of kinetic energy, potential energy and internal energy remains constant. Thus an increase in the speed of the fluid—implying an increase in its kinetic energy (dynamic pressure)—occurs with a simultaneous decrease in (the sum of) its potential energy (including the static pressure) and internal energy. If the fluid is flowing out of a reservoir, the sum of all forms of energy is the same because in a reservoir the energy per unit volume (the sum of pressure and gravitational potential ρ g h) is the same everywhere.\nBernoulli's principle can also be derived directly from Isaac Newton's second Law of Motion. If a small volume of fluid is flowing horizontally from a region of high pressure to a region of low pressure, then there is more pressure behind than in front. This gives a net force on the volume, accelerating it along the streamline.\nFluid particles are subject only to pressure and their own weight. If a fluid is flowing horizontally and along a section of a streamline, where the speed increases it can only be because the fluid on that section has moved from a region of higher pressure to a region of lower pressure; and if its speed decreases, it can only be because it has moved from a region of lower pressure to a region of higher pressure. Consequently, within a fluid flowing horizontally, the highest speed occurs where the pressure is lowest, and the lowest speed occurs where the pressure is highest.",

        "evidence": "We encode multi-domain data at the sentence level into vector representations. We then cluster these vector representations for each model using a Gaussian Mixture Model (GMM) with $k$ pre-defined clusters. We chose GMM as our clustering approach as it allows soft assignments (vs. hard assignments as in e.g. K-means) which we think fits the task better (as a sentence can be seen as drawn from a mixture of several domain). In all cases, to create a sentence representation we perform average pooling of the last hidden state (before the softmax layer) for each token in the sentence. To accelerate the clustering process and enable visualization we also experiment with performing dimensionality reduction with PCA over the sentence vectors before clustering them. We experiment with k in 5, 10 and 15 to test how adding flexibility would improve the domain clustering accuracy.\nWe propose two methods for domain data selection with pretrained language models.\nDomain-Cosine In this method we first compute a query vector, which is the element-wise average over the vector representations of the sentences in the small in-domain set. We use the same sentence-level average-pooling approach as described in Section SECREF2 to obtain sentence representations. We then retrieve the most relevant sentences in the training set by computing the cosine similarity of each sentence with this query vector and ranking the sentences accordingly.\nDomain-Finetune It is now common knowledge that pretrained language models are especially useful when fine-tuned for the task of interest in an end-to-end manner BIBREF41. In this method we fine-tune the pretrained LM for binary classification, where we use the in-domain sentences as positive examples, and randomly sampled general-domain sentences as negative examples. We then apply this classifier on the general-domain data and pick the sentences that are classified as positive as in-domain, or choose the top-k sentences as ranked by the classifier output distribution. This can be seen as an instance of positive-unlabeled learning for document-set expansion; see BIBREF42 for a recent discussion and methodology for this task.\nNegative Sampling with Pre-ranking One problem that may rise when randomly sampling negative examples is that unlabeled in-domain sentences from the general-domain data may be sampled as negative examples – deteriorating the classifier performance. To alleviate this issue, we perform a biased sampling of negative examples. We first rank the general-domain data using the Domain-Cosine method, and then sample negative examples under a certain threshold in the ranking (in our experiments we sampled from the bottom two-thirds). Table TABREF31 shows an ablation for such pre-ranking, measuring precision, recall and F1 for binary classification on a held-out set for each domain. When not using pre-ranking, as the training data for the domain is larger, the precision is lower – since more in-domain examples are drawn as negative samples. Using pre-ranking indeed alleviates this issue, achieving higher F1 scores in all cases. Given the results in Table TABREF31 we always use pre-ranking in the following experiments.\nWe chose GMM as our clustering approach as it allows soft assignments which we think fits the task better seen as drawn from a mixture of several domain.",

For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nSabour et al.

Only 0.25% of blurbs in the training set consist of more than 300 words, so this cut-off can be expected to have minor impact.\nThe non-text features are generated in a separate preprocessing step.

In the SoftMax output layer each unit corresponds to a class label. For sub-task A the output dimension is eight.

        "answer": "Automatic transcription of 5000 tokens through sequential neural models trained on the annotated part of the corpus",
        "evidence": "In order to make the corpus collection easier and faster, we adopted a semi-automatic procedure based on sequential neural models BIBREF19, BIBREF20. Since transcribing Arabish into Arabic is by far the most important information to study the Arabish code-system, the semi-automatic procedure concerns only transcription from Arabish to Arabic script. In order to proceed, we used the first group of (roughly) 6,000 manually transcribed tokens as training and test data sets in a 10-fold cross validation setting with 9-1 proportions for training and test, respectively. As we explained in the previous section, French tokens were removed from the data. More precisely, whole sentences containing non-transcribable French tokens (code-switching) were removed from the data. Since at this level there is no way for predicting when a French word can be transcribed into Arabic and when it has to be left unchanged, French tokens create some noise for an automatic, probabilistic model. After removing sentences with French tokens, the data reduced to roughly 5,000 tokens. We chose this amount of tokens for annotation blocks in our incremental annotation procedure.\nWe note that by combining sentence, paragraph and token index in the corpus, whole sentences can be reconstructed. However, from 5,000 tokens roughly 300 sentences could be reconstructed, which are far too few to be used for training a neural model. Instead, since tokens are transcribed at morpheme level, we split Arabish tokens into characters, and Arabic tokens into morphemes, and we treated each token itself as a sequence. Our model learns thus to map Arabish characters into Arabic morphemes.\nThe 10-fold cross validation with this setting gave a token-level accuracy of roughly 71%. This result is not satisfactory on an absolute scale, however it is more than encouraging taking into account the small size of our data. This result means that less than 3 tokens, on average, out of 10, must be corrected to increase the size of our corpus. With this model we automatically transcribed into Arabic morphemes, roughly, 5,000 additional tokens, corresponding to the second annotation block. This can be manually annotated in at least 7,5 days, but thanks to the automatic annotation accuracy, it was manually corrected into 3 days. The accuracy of the model on the annotation of the second block was roughly 70%, which corresponds to the accuracy on the test set. The manually-corrected additional tokens were added to the training data of our neural model, and a new block was automatically annotated and manually corrected. Both accuracy on the test set and on the annotation block remained at around 70%. This is because the block added to the training data was significantly different from the previous and from the third. Adding the third block to the training data and annotating a fourth block with the new trained model gave in contrast an accuracy of roughly 80%. This incremental, semi-automatic transcription procedure is in progress for the remaining blocks, but it is clear that it will make the corpus annotation increasingly easier and faster as the amount of training data will grow up.\nIn order to make the corpus collection easier and faster, we adopted a semi-automatic procedure based on sequential neural models BIBREF19, BIBREF20.\nInstead, since tokens are transcribed at morpheme level, we split Arabish tokens into characters, and Arabic tokens into morphemes, and we treated each token itself as a sequence.

Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension.

        "question": "Are the short 32-bit Binary PV-DBOW codes more efficient for indexing than long 128-bit semantic hashing codes?",
        "answer": "Yes, they are.",
        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nNote that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.",

American football, also known as gridiron, was first played in 1869 in the United States and mostly known in the United States and Canada. It rivals two teams on a rectangular field. Both teams have an offence as well as a defence formation. The first offence and defence of the match is decided by coin tossed where the winner decide for the first half of the match while the opposite match starts at the half-time mark. The offence team tries to take the oval-shaped ball to the other side of the field by passing or running it at each play. The defence team blocks the offence team so they get the balls themselves either by steeling it or when the offence team hasn’t progressed 10 yards in 4 plays. Then, offence team becomes defence and vice versa. When the offence team successfully reach the 10-yard lines, they obtain a new set of 4 plays to get to the endzone, where they obtain points when succeeding, called a touchdown. They also get points from kicking the ball within the goalpost. The winning team is the one with the most points at the end of the game. European football, also known as soccer, is a match between two teams of eleven players on a rectangular field, known as pitch. Players primarily use their feet to propel a sphere-shaped ball across the field into the rectangular shaped goal guarded by a goalkeeper. The goalkeeper is the only player of each team that can use his hands and arms on the ball within a specific region of the field close to their goals. The game is played continuously until a fault is committed or the ball exits the field.

        "evidence": "We experiment with five benchmark attacking methods for texts: FGM, FGVM, DeepFool BIBREF5, HotFlip BIBREF3) and TYC BIBREF4.\nTo perturb the discrete inputs, both FGM and FGVM introduce noises in the word embedding space via the fast gradient method BIBREF1 and reconstruct the input by mapping perturbed word embeddings to valid words via nearest neighbour search. Between FGM and FGVM, the former introduce noises that is proportional to the sign of the gradients while the latter introduce perturbations proportional to the gradients directly. The proportion is known as the overshoot value and denoted by $\\epsilon $. DeepFool uses the same trick to deal with discrete inputs except that, instead of using the fast gradient method, it uses the DeepFool method introduced in BIBREF8 for image to search for an optimal direction to perturb the word embeddings.\nUnlike the previous methods, HotFlip and TYC rely on performing one or more atomic flip operations to replace words while monitoring the label change given by the target classifier. In HotFlip, the directional derivatives w.r.t. flip operations are calculated and the flip operation that results in the largest increase in loss is selected. TYC is similar to FGM, FGVM and DeepFool in that it also uses nearest neighbour search to map the perturbed embeddings to valid words, but instead of using the perturbed tokens directly, it uses greedy search or beam search to flip original tokens to perturbed ones one at a time in order of their vulnerability.\nTEXTFOOLER, the only black-box attack method tested, is a query-based method. Since it assumes no access to the full architecture of the target classifier, it learns the order of vulnerability of tokens in an input sentence according to the change of prediction scores produced by the target classifier when a specific token is discarded. Once the order of vulnerability of words is identified, similar to HOTFLIP and TYC, it greedily replaces tokens in the order of vulnerability one-at-a-time until the prediction of the target classifier changes.",

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nWe introduce 4 BAE attack modes by replacing and inserting tokens, all of which are almost always stronger than previous baselines on 7 text classification datasets.",

        "answer": "Because team members have diversity of disciplinary backgrounds.",
        "evidence": "In June 2015, the operators of the online discussion site Reddit banned several communities under new anti-harassment rules. BIBREF0 used this opportunity to combine rich online data with computational methods to study a current question: Does eliminating these “echo chambers” diminish the amount of hate speech overall? Exciting opportunities like these, at the intersection of “thick” cultural and societal questions on the one hand, and the computational analysis of rich textual data on larger-than-human scales on the other, are becoming increasingly common.\nIndeed, computational analysis is opening new possibilities for exploring challenging questions at the heart of some of the most pressing contemporary cultural and social issues. While a human reader is better equipped to make logical inferences, resolve ambiguities, and apply cultural knowledge than a computer, human time and attention are limited. Moreover, many patterns are not obvious in any specific context, but only stand out in the aggregate. For example, in a landmark study, BIBREF1 analyzed the authorship of The Federalist Papers using a statistical text analysis by focusing on style, based on the distribution of function words, rather than content. As another example, BIBREF2 studied what defines English haiku and showed how computational analysis and close reading can complement each other. Computational approaches are valuable precisely because they help us identify patterns that would not otherwise be discernible.\nYet these approaches are not a panacea. Examining thick social and cultural questions using computational text analysis carries significant challenges. For one, texts are culturally and socially situated. They reflect the ideas, values and beliefs of both their authors and their target audiences, and such subtleties of meaning and interpretation are difficult to incorporate in computational approaches. For another, many of the social and cultural concepts we seek to examine are highly contested — hate speech is just one such example. Choices regarding how to operationalize and analyze these concepts can raise serious concerns about conceptual validity and may lead to shallow or obvious conclusions, rather than findings that reflect the depth of the questions we seek to address.\nThese are just a small sample of the many opportunities and challenges faced in computational analyses of textual data. New possibilities and frustrating obstacles emerge at every stage of research, from identification of the research question to interpretation of the results. In this article, we take the reader through a typical research process that involves measuring social or cultural concepts using computational methods, discussing both the opportunities and complications that often arise. In the Reddit case, for example, hate speech is measured, however imperfectly, by the presence of particular words semi-automatically extracted from a machine learning algorithm. Operationalizations are never perfect translations, and are often refined over the course of an investigation, but they are crucial.\nWe begin our exploration with the identification of research questions, proceed through data selection, conceptualization, and operationalization, and end with analysis and the interpretation of results. The research process sounds more or less linear this way, but each of these phases overlaps, and in some instances turns back upon itself. The analysis phase, for example, often feeds back into the original research questions, which may continue to evolve for much of the project. At each stage, our discussion is critically informed by insights from the humanities and social sciences, fields that have focused on, and worked to tackle, the challenges of textual analysis—albeit at smaller scales—since their inception.\nIn describing our experiences with computational text analysis, we hope to achieve three primary goals. First, we aim to shed light on thorny issues not always at the forefront of discussions about computational text analysis methods. Second, we hope to provide a set of best practices for working with thick social and cultural concepts. Our guidance is based on our own experiences and is therefore inherently imperfect. Still, given our diversity of disciplinary backgrounds and research practices, we hope to capture a range of ideas and identify commonalities that will resonate for many. And this leads to our final goal: to help promote interdisciplinary collaborations. Interdisciplinary insights and partnerships are essential for realizing the full potential of any computational text analysis that involves social and cultural concepts, and the more we are able to bridge these divides, the more fruitful we believe our work will be.\nStill, given our diversity of disciplinary backgrounds and research practices, we hope to capture a range of ideas and identify commonalities that will resonate for many.

        "evidence": "Question word answer phrases, parts of speech tags, parse feature, named entity and semantically related words are different features from answer type detection BIBREF18. We use question word and phrases as features for answer type detection. We consider the following features:\nTerm Frequency - Inverse Document Frequency (TF-IDF) is a popular method used to identify the importance of a word in a particular document. TF-IDF transforms text into meaningful numeric representation. This technique is widely used to extract features for Natural Language Processing (NLP) applications BIBREF25 BIBREF26.\nN-grams is n-back to back words in a text. Queries of a same class usually share word n-grams BIBREF0. In this system, we choose bi-gram for extracting features.\nWe use two setups (as done in BIBREF0) for our system. In the first setup, we eliminate the stop words from the text using another dataset containing only stop words. At second step, we work without eliminating the stop words from the text which gives better result than the first setup.\nMLP contains three layers - an input layer, an output layer and some hidden layers. Input layer receives the signal, the output layer gives a decision or prediction about the input and the computation of the MLP is conducted in the hidden layers. In our system, we use 100 layers. For weight optimization, we use Limited-memory Broyden–Fletcher–Goldfarb–Shanno (LBFGS) optimization algorithm.\nSVM gives an optimal hyper-plane and it maximizes the margin between classes. We use Radial Basis Function (RBF) kernel in our system to make decision boundary curve-shaped. For decision function shape, we use the original one-vs-one (ovo) decision function.\nNBC is based on Bayes' Theorem which gives probability of an event occurrence based on some conditions related to that event. We use Multinomial Naive Bayes Classifier with smoothing parameter equals to 0.1. A zero probability cancels the effects of all the other probabilities.\nStochastic gradient descent optimizes an objective function with suitable smoothness properties BIBREF27. It selects few examples randomly instead of whole data for each iteration. We use 'L2' regularization for reduction of overfitting.\nGradient Boosting Classifier produces a prediction model consisting of weak prediction models. Gradient boosting uses decision trees. We use 100 boosting stages in this work.\nK-NN is a supervised classification and regression algorithm. It uses the neighbours of the given sample to identify its class. K determines the number of neighbours needed to be considered. We set the value of K equals to 13 in this work.\nRF is an ensemble learning technique. It constructs large number of decision trees during training and then predicts the majority class. We use 500 decision trees in the forest and \"entropy\" function to measure the quality of a split.\nTable II shows the accuracy and F1 score for different classifiers with and without eliminating stop words while extracting features. Figure FIGREF21 shows the average results of different classifiers in a bar chart with and without eliminating stop words from the questions.\nOverall, SGD has shown the best performance on our dataset as it introduces non-linearity and uses back-propagation for updating parameter weights using loss function calculated on training set into classification. K-NN has shown the weakest performance overall, as this algorithm has a bad reputation of not working well in high dimensional data BIBREF28. MLP and SVM have shown similar performance. MLP takes advantage of multiple hidden layers in order to take non-linearly separable samples in a linearly separable condition. SVM accomplishes this same feat by taking the samples to a higher dimensional hyperplane where the samples are linearly separable. Gradient Boosting Classifier (GBC) and Random Forest (RF) both utilize a set of decision trees and achieve similar results (RF performs slightly without eliminating stop words). Naive Bayesian Classifier (NBC) shows performance on per with GBC and RF algorithms. The overall better performance of all the algorithms when provided with stop words show the importance of stop words in Bengali QA classification.\nFigure FIGREF22 shows the predictions of some particular questions by each of the classifiers. The input is a full question and the output is the class of the question.\nIn Table TABREF24, n = No. of training sample, p = No. of features, ntrees = No. of trees (for methods based on various trees), nsv = No. of support vectors, i = No. of iterations, h = No. of nodes in each hidden layer, k = No. of hidden layers and $\\overline{m}$ = the average no. of non-zero attributes per sample.\nWe use question word and phrases as features for answer type detection.",

        "evidence": "In the research field of Natural Language Processing (NLP) there are several tasks that contribute to understanding natural text. These tasks can manipulate natural language, such as tokenization process, and consequently can be used in other implementations, in order to extract syntactic or semantic information. One such task for syntactic components is Part of Speech Tagging (POS Tagging). Part of Speech Tagging in corpus linguistics is a process where a word is assigned with a label of the grammatical term, given the context it appears in. In many languages, POS Tagging models achieve an accuracy of 96 to 97 percent BIBREF0.\nPart of Speech Tagging for highly inflective languages, such as Greek is quite a difficult task. In the Greek Language, words can have different morphological forms, depending on the part of speech (verbs have up to ten different forms). For that purpose, there is a need for a tagset that can support morphological features for improvement of Greek POS Tagging BIBREF1.\nAnother main task for extracting semantic information is Named Entity Recognition (NER). Named Entity Recognition is a process where a word or a set of words reference to a world object. Most Natural Language Processing models classify named entities that describe people, locations, organizations, following the ENAMEX type or can be more complex by detecting numerical types, like percentages (NUMEX) or dates (TIMEX) BIBREF2.\nThe greek Part of Speech Tagging and Named Entity Recognition models presented in this paper were developed using the spaCy library BIBREF3. SpaCy is an open source, Natural Language Processing library that supports a variety of tasks, including POS Tagging, Named Entity Recognition, Dependency Parsing, etc. SpaCy uses sophisticated neural network-based models for the implementation of Natural Language Processing components that achieve state-of-the-art results in many of these tasks.\nIn the following chapters the process for implementing Part of Speech Tagging and Named Entity Recognition for the Greek Language is explained. A dataset with extended POS Tags was found and matched to a set of morphological rules, according to a treebank. The dataset was then processed, fed to the spaCy model and used for training. Similarly, for Named Entity Recognition, datasets from different sources were compared to a custom set of rules for named entities. Finally, different experiments were conducted for evaluating the accuracy of the models.\nSpaCy is an open source, Natural Language Processing library that supports a variety of tasks, including POS Tagging, Named Entity Recognition, Dependency Parsing, etc. SpaCy uses sophisticated neural network-based models for the implementation of Natural Language Processing components that achieve state-of-theart results in many of these tasks.",

This is due to several factors, such as the lexical and semantic challenges of domain-specific data that often include advanced argumentation and complex contextual information, the higher sparseness of relevant information sources, and the more pronounced lack of similarities between users' searches.\nA recent study on expert search strategies among healthcare information professionals BIBREF0 showed that, for a given search task, they spend an average of 60 minutes per collection or database, 3 minutes to examine the relevance of each document, and 4 hours of total search time. When written in steps, their search strategy spans over 15 lines and can reach up to 105 lines.\nWith the abundance of information sources in the medical domain, consumers are more and more faced with a similar challenge, one that needs dedicated solutions that can adapt to the heterogeneity and specifics of health-related information.\nDedicated Question Answering (QA) systems are one of the viable solutions to this problem as they are designed to understand natural language questions without relying on external information on the users.\nIn the context of QA, the goal of Recognizing Question Entailment (RQE) is to retrieve answers to a premise question ( INLINEFORM0 ) by retrieving inferred or entailed questions, called hypothesis questions ( INLINEFORM1 ) that already have associated answers. Therefore, we define the entailment relation between two questions as: a question INLINEFORM2 entails a question INLINEFORM3 if every answer to INLINEFORM4 is also a correct answer to INLINEFORM5 BIBREF1 .\nRQE is particularly relevant due to the increasing numbers of similar questions posted online BIBREF2 and its ability to solve differently the challenging issues of question understanding and answer extraction. In addition to being used to find relevant answers, these resources can also be used in training models able to recognize inference relations and similarity between questions.\nQuestion similarity has recently attracted international challenges BIBREF3 , BIBREF4 and several research efforts proposing a wide range of approaches, including Logistic Regression, Recurrent Neural Networks (RNNs), Long Short Term Memory cells (LSTMs), and Convolutional Neural Networks (CNNs) BIBREF5 , BIBREF6 , BIBREF1 , BIBREF7 .\nIn this paper, we study question entailment in the medical domain and the effectiveness of the end-to-end RQE-based QA approach by evaluating the relevance of the retrieved answers. Although entailment was attempted in QA before BIBREF8 , BIBREF9 , BIBREF10 , as far as we know, we are the first to introduce and evaluate a full medical question answering approach based on question entailment for free-text questions. Our contributions are:\nThe next section is dedicated to related work on question answering, question similarity and entailment.

        "answer": "Does eliminating these “echo chambers” diminish the amount of hate speech overall?",
        "evidence": "In June 2015, the operators of the online discussion site Reddit banned several communities under new anti-harassment rules. BIBREF0 used this opportunity to combine rich online data with computational methods to study a current question: Does eliminating these “echo chambers” diminish the amount of hate speech overall? Exciting opportunities like these, at the intersection of “thick” cultural and societal questions on the one hand, and the computational analysis of rich textual data on larger-than-human scales on the other, are becoming increasingly common.\nIndeed, computational analysis is opening new possibilities for exploring challenging questions at the heart of some of the most pressing contemporary cultural and social issues. While a human reader is better equipped to make logical inferences, resolve ambiguities, and apply cultural knowledge than a computer, human time and attention are limited. Moreover, many patterns are not obvious in any specific context, but only stand out in the aggregate. For example, in a landmark study, BIBREF1 analyzed the authorship of The Federalist Papers using a statistical text analysis by focusing on style, based on the distribution of function words, rather than content. As another example, BIBREF2 studied what defines English haiku and showed how computational analysis and close reading can complement each other. Computational approaches are valuable precisely because they help us identify patterns that would not otherwise be discernible.\nYet these approaches are not a panacea. Examining thick social and cultural questions using computational text analysis carries significant challenges. For one, texts are culturally and socially situated. They reflect the ideas, values and beliefs of both their authors and their target audiences, and such subtleties of meaning and interpretation are difficult to incorporate in computational approaches. For another, many of the social and cultural concepts we seek to examine are highly contested — hate speech is just one such example. Choices regarding how to operationalize and analyze these concepts can raise serious concerns about conceptual validity and may lead to shallow or obvious conclusions, rather than findings that reflect the depth of the questions we seek to address.\nThese are just a small sample of the many opportunities and challenges faced in computational analyses of textual data. New possibilities and frustrating obstacles emerge at every stage of research, from identification of the research question to interpretation of the results. In this article, we take the reader through a typical research process that involves measuring social or cultural concepts using computational methods, discussing both the opportunities and complications that often arise. In the Reddit case, for example, hate speech is measured, however imperfectly, by the presence of particular words semi-automatically extracted from a machine learning algorithm. Operationalizations are never perfect translations, and are often refined over the course of an investigation, but they are crucial.\nWe begin our exploration with the identification of research questions, proceed through data selection, conceptualization, and operationalization, and end with analysis and the interpretation of results. The research process sounds more or less linear this way, but each of these phases overlaps, and in some instances turns back upon itself. The analysis phase, for example, often feeds back into the original research questions, which may continue to evolve for much of the project. At each stage, our discussion is critically informed by insights from the humanities and social sciences, fields that have focused on, and worked to tackle, the challenges of textual analysis—albeit at smaller scales—since their inception.\nIn describing our experiences with computational text analysis, we hope to achieve three primary goals. First, we aim to shed light on thorny issues not always at the forefront of discussions about computational text analysis methods. Second, we hope to provide a set of best practices for working with thick social and cultural concepts. Our guidance is based on our own experiences and is therefore inherently imperfect. Still, given our diversity of disciplinary backgrounds and research practices, we hope to capture a range of ideas and identify commonalities that will resonate for many. And this leads to our final goal: to help promote interdisciplinary collaborations. Interdisciplinary insights and partnerships are essential for realizing the full potential of any computational text analysis that involves social and cultural concepts, and the more we are able to bridge these divides, the more fruitful we believe our work will be.\nIn June 2015, the operators of the online discussion site Reddit banned several communities under new anti-harassment rules.

Kennedy and Ted Kennedy, he was a prominent member of the Democratic Party and is viewed by some historians as an icon of modern American liberalism.\n\nKennedy was born into a wealthy, political family in Brookline, Massachusetts. After serving in the U.S. Naval Reserve from 1944 to 1946, Kennedy returned to his studies at Harvard University, and later received his law degree from the University of Virginia. He began his career as a correspondent for The Boston Post and as a lawyer at the Justice Department, but later resigned to manage his brother John's successful campaign for the U.S. Senate in 1952. The following year, he worked as an assistant counsel to the Senate committee chaired by Senator Joseph McCarthy. He gained national attention as the chief counsel of the Senate Labor Rackets Committee from 1957 to 1959, where he publicly challenged Teamsters President Jimmy Hoffa over the union's corrupt practices. Kennedy resigned from the committee to conduct his brother's successful campaign in the 1960 presidential election. He was appointed United States Attorney General at the age of 35, one of the youngest cabinet members in American history. He served as his brother's closest advisor until the latter's 1963 assassination.\n\nHis tenure is known for advocating for the civil rights movement, the fight against organized crime and the Mafia, and involvement in U.S. foreign policy related to Cuba. He authored his account of the Cuban Missile Crisis in a book titled Thirteen Days. As attorney general, he authorized the Federal Bureau of Investigation (FBI) to wiretap Martin Luther King Jr. and the Southern Christian Leadership Conference on a limited basis. After his brother's assassination, he remained in office during the Presidency of Lyndon B. Johnson for several months. He left to run for the United States Senate from New York in 1964 and defeated Republican incumbent Kenneth Keating. In office, Kennedy opposed U.S. involvement in the Vietnam War and raised awareness of poverty by sponsoring legislation designed to lure private business to blighted communities (i.e., Bedford Stuyvesant Restoration project). He was an advocate for issues related to human rights and social justice by traveling abroad to eastern Europe, Latin America, and South Africa, and formed working relationships with Martin Luther King Jr., Cesar Chavez, and Walter Reuther.\n\nIn 1968, Kennedy became a leading candidate for the Democratic nomination for the presidency by appealing to poor, African American, Hispanic, Catholic, and young voters. His main challenger in the race was Senator Eugene McCarthy. Shortly after winning the California primary around midnight on June 5, 1968, Kennedy was shot by Sirhan Sirhan, a 24-year-old Palestinian, allegedly in retaliation for his support of Israel following the 1967 Six-Day War. Kennedy died 25 hours later. Sirhan was arrested, tried, and convicted, though Kennedy's assassination, like his brother's, continues to be the subject of widespread analysis and numerous conspiracy theories.",

        "answer": "Yes, it can.",
        "evidence": "We evaluated our approach in three different experiments based on human ratings. We divided the volunteers into two groups—domain experts and non-experts. The group of domain experts comprised 66 persons while there were 20 non-experts forming the second group. In the first experiment, an OWL axiom and its verbalization were shown to the experts who were asked to rate the verbalization regarding the two following measures according to gardent2017creating: (1) Adequacy: Does the text contain only and all the information from the data? (2) Fluency: Does the text sound fluent and natural?. For both measures the volunteers were asked to rate on a scale from 1 (Very Bad) to 5 (Very Good). The experiment was carried out using 41 axioms of the Koala ontology. Because of the complexity of OWL axioms, only domain experts were asked to perform this experiment.\nIn the second experiment, a set of triples describing a single resource and their verbalization were shown to the volunteers. The experts were asked to rate the verbalization regarding adequacy, fluency and completeness, i.e., whether all triples have been covered. The non-experts were only asked to rate the fluency. The experiment was carried out using 6 DBpedia resources.In the third experiment, the verbalization of an OWL class and 5 resources were shown to the human raters. For non-experts, the resources have been verbalized as well, while for domain experts the resources were presented as triples. The task of the raters was to identify the resource that fits the class description and, thus, is an instance of the class. We used 4 different OWL axioms and measured the amount of correct identified class instances.\nResults In our first series of experiments, the verbalization of OWL axioms, we achieved an average adequacy of 4.4 while the fluency reached 4.38. In addition, more than 77% of the verbalizations were assigned the maximal adequacy (i.e., were assigned a score of 5, see Fig. FIGREF38). The maximal score for fluency was achieved in more than 69% of the cases (see Fig. FIGREF38). This clearly indicates that the verbalization of axioms generated by LD2NL can be easily understood by domain experts and contains all the information necessary to access the input OWL class expression.\nExperiments on the verbalization of summaries for RDF resources revealed that verbalizing resource summaries is a more difficult task. While the adequacy of the verbalization was assigned an average score of 3.92 by experts (see Fig. FIGREF39), the fluency was assigned a average score of 3.47 by experts and 3.0 by non-experts (see Fig. FIGREF39). What these results suggest is that (1) our framework generates sentences that are close to that which a domain expert would also generate (adequacy). However (2) while the sentence is grammatically sufficient for the experts, it is regarded by non-domain experts (which were mostly linguists, i.e., the worst-case scenario for such an evaluation) as being grammatically passably good but still worthy of improvement. The completeness rating achieves a score of 4.31 on average (see Fig. FIGREF39). This was to be expected as we introduced a rule to shorten the description of resources that contain more than 5 triples which share a common subject and predicate. Finally, we measured how well the users and experts were able to understand the meaning of the text generated by our approach. As expected, the domain experts outperform the non-expert users by being able to find the answers to 87.2% of the questions. The score achieved by non-domain experts, i.e., 80%, still suggest that our framework is able to bridge the gap pertaining to understand RDF and OWL for non-experts from 0% to 80%, which is more than 91.8% of the performance of experts.\nDiscussion Our evaluation results suggest that the verbalization of these languages is a non-trivial task that can be approached by using a bottom-up approach. As expected, the verbalization of short expressions leads to sentences which read as if they have been generated by a human. However, due to the complexity of the semantics that can be expressed by the languages at hand, long expressions can sound mildly artificial. Our results however also suggest that although the text generated can sound artificial, it is still clear enough to enable non-expert users to achieve results that are comparable to those achieved by experts. Hence, our first conclusion is that our framework clearly serves its purpose. Still, potential improvements can be derived from the results achieved during the experiments. In particular, we will consider the used of attention-based encoder-decoder networks to improve the fluency of complex sentences.\nThis clearly indicates that the verbalization of axioms generated by LD2NL can be easily understood by domain experts and contains all the information necessary to access the input OWL class expression",

        "answer": "This paper analyzes the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories.",
        "evidence": "Cancer is one of the leading causes of death in the world, with over 80,000 deaths registered in Canada in 2017 (Canadian Cancer Statistics 2017). A computer-aided system for cancer diagnosis usually involves a pathologist rendering a descriptive report after examining the tissue glass slides obtained from the biopsy of a patient. A pathology report contains specific analysis of cells and tissues, and other histopathological indicators that are crucial for diagnosing malignancies. An average sized laboratory may produces a large quantity of pathology reports annually (e.g., in excess of 50,000), but these reports are written in mostly unstructured text and with no direct link to the tissue sample. Furthermore, the report for each patient is a personalized document and offers very high variability in terminology due to lack of standards and may even include misspellings and missing punctuation, clinical diagnoses interspersed with complex explanations, different terminology to label the same malignancy, and information about multiple carcinoma appearances included in a single report BIBREF0 .\nIn Canada, each Provincial and Territorial Cancer Registry (PTCR) is responsible for collecting the data about cancer diseases and reporting them to Statistics Canada (StatCan). Every year, Canadian Cancer Registry (CCR) uses the information sources of StatCan to compile an annual report on cancer and tumor diseases. Many countries have their own cancer registry programs. These programs rely on the acquisition of diagnostic, treatment, and outcome information through manual processing and interpretation from various unstructured sources (e.g., pathology reports, autopsy/laboratory reports, medical billing summaries). The manual classification of cancer pathology reports is a challenging, time-consuming task and requires extensive training BIBREF0 .\nWith the continued growth in the number of cancer patients, and the increase in treatment complexity, cancer registries face a significant challenge in manually reviewing the large quantity of reports BIBREF1 , BIBREF0 . In this situation, Natural Language Processing (NLP) systems can offer a unique opportunity to automatically encode the unstructured reports into structured data. Since, the registries already have access to the large quantity of historically labeled and encoded reports, a supervised machine learning approach of feature extraction and classification is a compelling direction for making their workflow more effective and streamlined. If successful, such a solution would enable processing reports in much lesser time allowing trained personnel to focus on their research and analysis. However, developing an automated solution with high accuracy and consistency across wide variety of reports is a challenging problem.\nFor cancer registries, an important piece of information in a pathology report is the associated ICD-O code which describes the patient's histological diagnosis, as described by the World Health Organization's (WHO) International Classification of Diseases for Oncology BIBREF2 . Prediction of the primary diagnosis from a pathology report provides a valuable starting point for exploration of machine learning techniques for automated cancer surveillance. A major application for this purpose would be “auto-reporting” based on analysis of whole slide images, the digitization of the biopsy glass slides. Structured, summarized and categorized reports can be associated with the image content when searching in large archives. Such as system would be able to drastically increase the efficiency of diagnostic processes for the majority of cases where in spite of obvious primary diagnosis, still time and effort is required from the pathologists to write a descriptive report.\nThe primary objective of our study is to analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories. We demonstrate that TF-IDF feature vectors combined with linear SVM or XGBoost classifier can be an effective method for classification of the reports, achieving up to 83% accuracy. We also show that TF-IDF features are capable of identifying important keywords within a pathology report. Furthermore, we have created a new dataset consisting of 1,949 pathology reports across 37 primary diagnoses. Taken together, our exploratory experiments with a newly introduced dataset on pathology reports opens many new opportunities for researchers to develop a scalable and automatic information extraction from unstructured pathology reports.\nThe primary objective of our study is to analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories.",

        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nThe frame-semantic parser is built based on FrameNet and BabelNet where FrameNet is used to capture the meaning of the sentence and BabelNet is used to disambiguate the meaning of the extracted entities from the sentence.",

Hemingway biographer Jeffrey Meyers writes that it is now \"recognized as Hemingway's greatest work\" and Hemingway scholar Linda Wagner-Martin calls it his most important novel. The novel was published in the United States in October 1926 by Scribner's. A year later, Jonathan Cape published the novel in London under the title Fiesta.

Hemingway presents his notion that the \"Lost Generation\"—considered to have been decadent, dissolute and irretrievably damaged by World War I—was in fact resilient and strong.

        "question": "Extract the pros and cons of different speech synthesis technologies.",
        "evidence": "The most important qualities of a speech synthesis system are naturalness and intelligibility. Naturalness describes how closely the output sounds like human speech, while intelligibility is the ease with which the output is understood. The ideal speech synthesizer is both natural and intelligible. Speech synthesis systems usually try to maximize both characteristics.\n\nThe two primary technologies generating synthetic speech waveforms are concatenative synthesis and formant synthesis. Each technology has strengths and weaknesses, and the intended uses of a synthesis system will typically determine which approach is used.\n\nConcatenation synthesis\nMain article: Concatenative synthesis\nConcatenative synthesis is based on the concatenation (stringing together) of segments of recorded speech. Generally, concatenative synthesis produces the most natural-sounding synthesized speech. However, differences between natural variations in speech and the nature of the automated techniques for segmenting the waveforms sometimes result in audible glitches in the output. There are three main sub-types of concatenative synthesis.\n\nUnit selection synthesis\nUnit selection synthesis uses large databases of recorded speech. During database creation, each recorded utterance is segmented into some or all of the following: individual phones, diphones, half-phones, syllables, morphemes, words, phrases, and sentences. Typically, the division into segments is done using a specially modified speech recognizer set to a \"forced alignment\" mode with some manual correction afterward, using visual representations such as the waveform and spectrogram. An index of the units in the speech database is then created based on the segmentation and acoustic parameters like the fundamental frequency (pitch), duration, position in the syllable, and neighboring phones. At run time, the desired target utterance is created by determining the best chain of candidate units from the database (unit selection). This process is typically achieved using a specially weighted decision tree.\n\nUnit selection provides the greatest naturalness, because it applies only a small amount of digital signal processing (DSP) to the recorded speech. DSP often makes recorded speech sound less natural, although some systems use a small amount of signal processing at the point of concatenation to smooth the waveform. The output from the best unit-selection systems is often indistinguishable from real human voices, especially in contexts for which the TTS system has been tuned. However, maximum naturalness typically require unit-selection speech databases to be very large, in some systems ranging into the gigabytes of recorded data, representing dozens of hours of speech. Also, unit selection algorithms have been known to select segments from a place that results in less than ideal synthesis (e.g. minor words become unclear) even when a better choice exists in the database. Recently, researchers have proposed various automated methods to detect unnatural segments in unit-selection speech synthesis systems.\n\nDiphone synthesis\nDiphone synthesis uses a minimal speech database containing all the diphones (sound-to-sound transitions) occurring in a language. The number of diphones depends on the phonotactics of the language: for example, Spanish has about 800 diphones, and German about 2500. In diphone synthesis, only one example of each diphone is contained in the speech database. At runtime, the target prosody of a sentence is superimposed on these minimal units by means of digital signal processing techniques such as linear predictive coding, PSOLA or MBROLA. or more recent techniques such as pitch modification in the source domain using discrete cosine transform. Diphone synthesis suffers from the sonic glitches of concatenative synthesis and the robotic-sounding nature of formant synthesis, and has few of the advantages of either approach other than small size. As such, its use in commercial applications is declining,[citation needed] although it continues to be used in research because there are a number of freely available software implementations. An early example of Diphone synthesis is a teaching robot, Leachim, that was invented by Michael J. Freeman. Leachim contained information regarding class curricular and certain biographical information about the students whom it was programmed to teach. It was tested in a fourth grade classroom in the Bronx, New York.\n\nDomain-specific synthesis\nDomain-specific synthesis concatenates prerecorded words and phrases to create complete utterances. It is used in applications where the variety of texts the system will output is limited to a particular domain, like transit schedule announcements or weather reports. The technology is very simple to implement, and has been in commercial use for a long time, in devices like talking clocks and calculators. The level of naturalness of these systems can be very high because the variety of sentence types is limited, and they closely match the prosody and intonation of the original recordings.[citation needed]\n\nBecause these systems are limited by the words and phrases in their databases, they are not general-purpose and can only synthesize the combinations of words and phrases with which they have been preprogrammed. The blending of words within naturally spoken language however can still cause problems unless the many variations are taken into account. For example, in non-rhotic dialects of English the \"r\" in words like \"clear\" /ˈklɪə/ is usually only pronounced when the following word has a vowel as its first letter (e.g. \"clear out\" is realized as /ˌklɪəɹˈʌʊt/). Likewise in French, many final consonants become no longer silent if followed by a word that begins with a vowel, an effect called liaison. This alternation cannot be reproduced by a simple word-concatenation system, which would require additional complexity to be context-sensitive.\n\nFormant synthesis\nFormant synthesis does not use human speech samples at runtime. Instead, the synthesized speech output is created using additive synthesis and an acoustic model (physical modelling synthesis). Parameters such as fundamental frequency, voicing, and noise levels are varied over time to create a waveform of artificial speech. This method is sometimes called rules-based synthesis; however, many concatenative systems also have rules-based components. Many systems based on formant synthesis technology generate artificial, robotic-sounding speech that would never be mistaken for human speech. However, maximum naturalness is not always the goal of a speech synthesis system, and formant synthesis systems have advantages over concatenative systems. Formant-synthesized speech can be reliably intelligible, even at very high speeds, avoiding the acoustic glitches that commonly plague concatenative systems. High-speed synthesized speech is used by the visually impaired to quickly navigate computers using a screen reader. Formant synthesizers are usually smaller programs than concatenative systems because they do not have a database of speech samples. They can therefore be used in embedded systems, where memory and microprocessor power are especially limited. Because formant-based systems have complete control of all aspects of the output speech, a wide variety of prosodies and intonations can be output, conveying not just questions and statements, but a variety of emotions and tones of voice.\n\nExamples of non-real-time but highly accurate intonation control in formant synthesis include the work done in the late 1970s for the Texas Instruments toy Speak & Spell, and in the early 1980s Sega arcade machines and in many Atari, Inc. arcade games using the TMS5220 LPC Chips. Creating proper intonation for these projects was painstaking, and the results have yet to be matched by real-time text-to-speech interfaces.\n\nArticulatory synthesis\nArticulatory synthesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there. The first articulatory synthesizer regularly used for laboratory experiments was developed at Haskins Laboratories in the mid-1970s by Philip Rubin, Tom Baer, and Paul Mermelstein. This synthesizer, known as ASY, was based on vocal tract models developed at Bell Laboratories in the 1960s and 1970s by Paul Mermelstein, Cecil Coker, and colleagues.\n\nUntil recently, articulatory synthesis models have not been incorporated into commercial speech synthesis systems. A notable exception is the NeXT-based system originally developed and marketed by Trillium Sound Research, a spin-off company of the University of Calgary, where much of the original research was conducted. Following the demise of the various incarnations of NeXT (started by Steve Jobs in the late 1980s and merged with Apple Computer in 1997), the Trillium software was published under the GNU General Public License, with work continuing as gnuspeech. The system, first marketed in 1994, provides full articulatory-based text-to-speech conversion using a waveguide or transmission-line analog of the human oral and nasal tracts controlled by Carré's \"distinctive region model\".\n\nMore recent synthesizers, developed by Jorge C. Lucero and colleagues, incorporate models of vocal fold biomechanics, glottal aerodynamics and acoustic wave propagation in the bronchi, trachea, nasal and oral cavities, and thus constitute full systems of physics-based speech simulation.",

Former frontman for The Marshwiggles and Thom Scarecrow, Wolfenberger has three solo CDs to date; Tales From Thom Scarecrow, and World of the Satisfy'n Place on Blue Jordan Records and more recently in 2006 on Fundamental Records, Portrait of Narcissus. Wolfenberger also toured and recorded as a member of Mark Olson and Victoria Williams' Original Harmony Ridge Creekdippers. Wolfenberger occasionally records under the pseudonym Sunrise for Someone.\n\nBiography\nDave Wolfenberger was part of a band called Selah while a History student at the University of Cincinnati in the early 1990s. This band was later renamed The Remnant due to another band having the same name. They played monthly concerts at a local church. One of their songs, \"I Am Here\" was written by Dave Wolfenberger and helped at least one person, me, accept Jesus to become his personal Savior. This band came out with two tapes of their music. The first album contained the song \"I AM HERE.\" While I have been told there are at least two versions of this song, one version of the song was recently sung by David and can be listened to at Crossroads Church website though the external link I have placed in the external links. The link will be preceded by the number 2.\n\nIn 1997 Wolfenberger's band the Marshwiggles released their first and only album Stone Soup on the local Cincinnati label Blue Jordan Records. It was played nationally and the band toured regionally to sizable crowds but broke up during the recording of their second album just prior to its completion and release.[citation needed] This album has never been released although tracks from it have shown up on Blue Jordan compilations. Wolfenberger then formed the band Thom Scarecrow with acoustic guitarist Jason Dennie and fellow Marshwiggles, Tony Moore and Joshua Seurkamp. This would be a short-lived ensemble lasting just over a year.\n\nIn 1999 Wolfenberger's first solo album, Tales From Thom Scarecrow was released and won him Artist of the Year in his hometown at the Cincinnati Entertainment Awards as well as notoriety abroad from such notable media as the Corriere della Sera in Milan, Italy which stated that \"Wolfenberger puts forth folk with dark nuances, the grand introspective songs are illuminated with emotions in this exhibition of his life.\"\n\nIn 2000 he joined iconoclastic songwriters Mark Olson and Victoria Williams as a touring and recording member of the Original Harmony Ridge Creekdippers. In 2001 while still touring with the Creekdippers Wolfenberger recorded his second solo album with his band entitled World of the Satisfyn' Place. This album was decidedly more roots oriented than his first (a return to his style with the Marshwiggles and Thom Scarecrow) and swung wildly from raucous to thoughtful on a song to song basis., It was even more well received by the critics. The Detroit Metro Times stated that \"Wolfenberger ambles between homespun Appalachian traditions and classic pop and country forms with an unwavering dedication to simple, gorgeous melodies that are alternately uplifting and devastating.\" While in Britain, Americana-UK called it \"a 100% solid gold classic\". and his hometown Cincinnati press named it \"one of the best albums (local or national) of the year\".\n\nIn the following two years he would appear on two Creekdipper albums, release a free folk gospel album under the pseudonym Sunrise for Someone and eventually in 2003 stop touring and recording with the Creekdippers although maintaining a close relationship, which would become apparent with the release of his third solo album entitled Portrait of Narcissus in 2006 which featured fellow Creekdippers, Victoria Williams, Joshua Grange (by then a regular member of Dwight Yoakam's band), and fellow independent folkie Michelle Shocked. This would be Wolfenberger's first album to be distributed beyond America and Europe into Asia and Australia due to its release by recently revived Fundamental Records. It would even end up at No. 12 on the independent Euro Americana Chart\n\nIn July 2008 Wolfenberger recorded and made available another folk gospel project under the pseudonym Sunrise for Someone entitled Summer Lake Champion. In August of the same year he released Just Burned Upon The Page a live and mostly solo recording of 7 songs. The proceeds benefit the Juvenile Diabetes Research Foundation.",

        "evidence": "Natural Language Generation (NLG) plays a critical role in Spoken Dialogue Systems (SDS) with task is to convert a meaning representation produced by the Dialogue Manager into natural language utterances. Conventional approaches still rely on comprehensive hand-tuning templates and rules requiring expert knowledge of linguistic representation, including rule-based BIBREF0 , corpus-based n-gram models BIBREF1 , and a trainable generator BIBREF2 .\nRecently, Recurrent Neural Networks (RNNs) based approaches have shown promising performance in tackling the NLG problems. The RNN-based models have been applied for NLG as a joint training model BIBREF3 , BIBREF4 and an end-to-end training model BIBREF5 . A recurring problem in such systems is requiring annotated datasets for particular dialogue acts (DAs). To ensure that the generated utterance representing the intended meaning of the given DA, the previous RNN-based models were further conditioned on a 1-hot vector representation of the DA. BIBREF3 introduced a heuristic gate to ensure that all the slot-value pair was accurately captured during generation. BIBREF4 subsequently proposed a Semantically Conditioned Long Short-term Memory generator (SC-LSTM) which jointly learned the DA gating signal and language model.\nMore recently, Encoder-Decoder networks BIBREF6 , BIBREF7 , especially the attentional based models BIBREF8 , BIBREF9 have been explored to solve the NLG tasks. The Attentional RNN Encoder-Decoder BIBREF10 (ARED) based approaches have also shown improved performance on a variety of tasks, e.g., image captioning BIBREF11 , BIBREF12 , text summarization BIBREF13 , BIBREF14 .\nWhile the RNN-based generators with DA gating-vector can prevent the undesirable semantic repetitions, the ARED-based generators show signs of better adapting to a new domain. However, none of the models show significant advantage from out-of-domain data. To better analyze model generalization to an unseen, new domain as well as model leveraging the out-of-domain sources, we propose a new architecture which is an extension of the ARED model. In order to better select, aggregate and control the semantic information, a Refinement Adjustment LSTM-based component (RALSTM) is introduced to the decoder side. The proposed model can learn from unaligned data by jointly training the sentence planning and surface realization to produce natural language sentences. We conducted experiments on four different NLG domains and found that the proposed methods significantly outperformed the state-of-the-art methods regarding BLEU BIBREF15 and slot error rate ERR scores BIBREF4 .

Phenotype definitions, dataset distribution, patient note statistics, inter-operator error, and the results of baseline models were reported to demonstrate that the dataset is well-suited for the development of both rule-based and statistical models for patient phenotyping. We hope that the release of this dataset will accelerate the development of algorithms for patient phenotyping, which in turn would significantly help medical research progress faster.",

        "answer": "The authors perform classification experiments on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019.",

        "evidence": "Bidirectional Encoder Representations from Transformers (BERT) is a novel Transformer BIBREF0 model, which recently achieved state-of-the-art performance in several language understanding tasks, such as question answering, natural language inference, semantic similarity, sentiment analysis, and others BIBREF1. While well-suited to dealing with relatively short sequences, Transformers suffer from a major issue that hinders their applicability in classification of long sequences, i.e. they are able to consume only a limited context of symbols as their input BIBREF2.\nThere are several natural language (NLP) processing tasks that involve such long sequences. Of particular interest are topic identification of spoken conversations BIBREF3, BIBREF4, BIBREF5 and call center customer satisfaction prediction BIBREF6, BIBREF7, BIBREF8, BIBREF9. Call center conversations, while usually quite short and to the point, often involve agents trying to solve very complex issues that the customers experience, resulting in some calls taking even an hour or more. For speech analytics purposes, these calls are typically transcribed using an automatic speech recognition (ASR) system, and processed in textual representations further down the NLP pipeline. These transcripts sometimes exceed the length of 5000 words. Furthermore, temporal information might play an important role in tasks like CSAT. For example, a customer may be angry at the beginning of the call, but after her issue is resolved, she would be very satisfied with the way it was handled. Therefore, simple bag of words models, or any model that does not include temporal dependencies between the inputs, may not be well-suited to handle this category of tasks. This motivates us to employ model such as BERT in this task.\nIn this paper, we propose a method that builds upon BERT's architecture. We split the input text sequence into shorter segments in order to obtain a representation for each of them using BERT. Then, we use either a recurrent LSTM BIBREF10 network, or another Transformer, to perform the actual classification. We call these techniques Recurrence over BERT (RoBERT) and Transformer over BERT (ToBERT). Given that these models introduce a hierarchy of representations (segment-wise and document-wise), we refer to them as Hierarchical Transformers. To the best of our knowledge, no attempt has been done before to use the Transformer architecture for classification of such long sequences.\nOur novel contributions are:\nTwo extensions - RoBERT and ToBERT - to the BERT model, which enable its application in classification of long texts by performing segmentation and using another layer on top of the segment representations.\nState-of-the-art results on the Fisher topic classification task.\nSignificant improvement on the CSAT prediction task over the MS-CNN model.\nWhile well-suited to dealing with relatively short sequences, Transformers suffer from a major issue that hinders their applicability in classification of long sequences, i.e. they are able to consume only a limited context of symbols as their input [3].",

Each token INLINEFORM6 consists of a word, its POS and its type. There are five defined word types: English, Thai, punctuation, digits, and spaces.\nThe tag set INLINEFORM0 is populated based on the considered task. In Thai sentence segmentation, the assigned tags are INLINEFORM1 and INLINEFORM2 ; INLINEFORM3 denotes that the corresponding word is a sentence boundary considered as the beginning of a sentence, while and INLINEFORM4 denotes that the word is not a sentence boundary. Meanwhile, there are four tags in the punctuation restoration task. Words not followed by any punctuation are tagged with INLINEFORM5 . Words that are followed by a period “.”, comma “,” or question mark “?” are tagged to INLINEFORM6 , INLINEFORM7 , and INLINEFORM8 , respectively.\narchitecture/MainArchitecture\nOur model architecture is based on Bi-LSTM-CRF, as shown in Fig. . The model is divided into three modules. The first, low-level module, consists of two separate structures: local and distant structures. The second, high-level module, contains a sequence of stacked bidirectional LSTM and self-attention layers. The final module, the prediction module, is responsible for predicting the tags INLINEFORM0 . Each module is described more completely in the next three subsections.\nA sequence of word tokens is input into the low-level module. The input tokens pass through two structures. The first structure generates a sequence of local representation vectors INLINEFORM0 , and the second structure generates low-level distant representation vectors INLINEFORM1 . After obtaining both sequences of representation vectors, the local representation vectors are fed to the Bi-LSTM to obtain the recurrent representation vectors INLINEFORM2 , as shown in recurrentrep. Then, the recurrent and distant representation vectors are concatenated to form the low-level representation vector INLINEFORM3 , as shown in low-level: DISPLAYFORM0 DISPLAYFORM1 \nThis structure is shown as the left submodule of the low-level module in Fig. . It extracts the local representation vectors INLINEFORM0 . Its input tokens are used to create n-gram tokens, which are unigrams INLINEFORM1 , bigrams INLINEFORM2 , and trigrams INLINEFORM3 . Each n-gram token is represented as an embedding vector, which is classified as a unigram embedding vector INLINEFORM4 , a bigram embedding vector INLINEFORM5 or a trigram embedding vector INLINEFORM6 . Each vector INLINEFORM7 is mapped from a token by gram embedding INLINEFORM8 , which is a concatenated vector of the word embedding INLINEFORM9 , POS embedding INLINEFORM10 and type embedding INLINEFORM11 , as shown in eq:embedding: DISPLAYFORM0 \nEach n-gram token at timestep INLINEFORM0 is generated by the previous, present and next token and embedded into vectors as shown in uni,bi,tri. The unigram embedding at timestep INLINEFORM1 is a unigram embedding of the current token INLINEFORM2 . The bigram embedding vector at timestep INLINEFORM3 is a bigram embedding of the previous and present tokens INLINEFORM4 , and the trigram embedding vector at timestep INLINEFORM5 is a trigram embedding of the previous, present and next tokens INLINEFORM6 : DISPLAYFORM0 DISPLAYFORM1 \nAt each timestep INLINEFORM0 , a local representation vector INLINEFORM1 is combined from the n-gram embedding vectors generated from the context around INLINEFORM2 . A combination of embedding vectors, which is used to construct a local representation vector, is shown in n-gramcombination. A combination consists of the unigram, bigram, and trigram embedding vectors at timesteps INLINEFORM3 , INLINEFORM4 and INLINEFORM5 and it is a concatenation of all the embedding vectors: DISPLAYFORM0 \nThe distant structure, which is a self-attention module, is shown in Fig. on the right side of the low-level module. The structure extracts low-level distant representation vectors INLINEFORM0 from a sequence of unigram embedding vectors INLINEFORM1 , as shown in distantattention. In this case, the self-attention module is a scaled dot-product attention BIBREF11 , where key, query, and value vectors are the linear projections of the unigram embedding vectors shown in Fig. . The linear transformations for key, query, and value are learned separately and updated in the model through backpropagation. The output vector, which is the scaled dot-product attention at each timestep, is concatenated with the input vector INLINEFORM2 and projected by a linear transformation. That projected vector is the output vector of a self-attention module, which is a low-level distant representation vector.\narchitecture/selfattention DISPLAYFORM0 \nThe low-level representation vectors INLINEFORM0 are used as the input for this module, which outputs the high-level representation vectors INLINEFORM1 whose calculation is shown in high-level. The high-level module, as shown in Fig. , is composed of a stacked bidirectional LSTM and a self-attention modules. A stacked bidirectional LSTM contains K layers of bidirectional LSTMs in which the output from the previous bidirectional LSTM layer is the input of the next bidirectional LSTM layer. The self-attention part of this structure is the same as that in the low-level distant structure. The self-attention module helps to generate the high-level distant representation vectors that are output by the high-level module. DISPLAYFORM0 \nThe prediction module is the last module. It includes two layers: a fully connected layer and a CRF layer. In the fully connected layer, the output vectors from the high-level module are projected by a linear transformation as shown in virtual. The purpose of this layer is to create the virtual logit vectors INLINEFORM0 , which represent the probability distribution for CVT, as discussed in Section SECREF21 . Therefore, the number of dimensions of logits equals the number of possible tags in each task: DISPLAYFORM0 \nThe CRF layer is responsible for predicting the tag INLINEFORM0 of a token at each timestep, as shown in crf. The layer receives a sequence of virtual logit vectors ( INLINEFORM1 ) as input and then decodes them to a sequence of tags INLINEFORM2 using the Viterbi algorithm. DISPLAYFORM0 \nThe model is divided into three modules. The first, low-level module, consists of two separate structures: local and distant structures. The second, high-level module, contains a sequence of stacked bidirectional LSTM and self-attention layers. The final module, the prediction module, is responsible for predicting the tags ~",

        "evidence": "In order to select valuable and appropriate shared features for different tasks, we design a selected sharing layer following the shared layer. The selected sharing layer consists of two cells: gated sharing cell for filtering useless features and attention sharing cell for focusing on valuable shared features for specific tasks. The description of this layer is depicted in Figure FIGREF6 and Figure FIGREF15. In the following, we introduce two cells in details.\nGated Sharing Cell Inspired by forgotten gate mechanism of LSTM BIBREF32 and GRU BIBREF33, we design a single gated cell to filter useless shared features from shared layer. There are two reasons why we adopt single-gate mechanism. One is that transformer encoder in shared layer can efficiently capture the features of long-range dependencies. The features do not need to capture repeatedly by multiple complex gate mechanisms of LSTM and GRU. The other is that single-gate mechanism is more convenient for training BIBREF34. Formally, the gated sharing cell can be expressed as follows:\nwhere ${\\rm \\textbf {H}}_{shared}\\! \\in \\! \\mathbb {R}^{1 \\times l(d_p+d_w)}$ denotes the outputs of shared layer upstream, ${\\rm \\textbf {W}}_{fake} \\in \\mathbb {R}^{l(d_p+d_w) \\times l(d_p+d_w)}$ and ${\\rm \\textbf {b}}_{fake} \\in \\mathbb {R}^{1 \\times l(d_p+d_w)}$ are trainable parameters. $\\sigma $ is a non-linear activation - sigmoid, which makes final choices for retaining and discarding features in shared layer.\nThen the shared features after filtering via gated sharing cell ${\\rm \\textbf {g}}_{fake}$ for the task of fake news detection are represented as:\nwhere $\\odot $ denotes element-wise multiplication.\nSimilarly, for the auxiliary task - the task of stance detection, filtering process in the gated sharing cell is the same as the task of fake news detection, so we do not reiterate them here.\nAttention Sharing Cell To focus on helpful shared features that are beneficial to specific tasks from upstream shared layer, we devise an attention sharing cell based on attention mechanism. Specifically, this cell utilizes input embeddings of the specific task to weight shared features for paying more attention to helpful features. The inputs of this cell include two matrixes: the input embeddings of the specific task and the shared features of both tasks. The basic attention architecture of this cell, the same as shared-private feature extractor, also adopts transformer encoder (the details in subsection SECREF8). However, in this architecture, query matrix and key matrix are not projections of the same matrix, i.e., query matrix ${\\rm \\textbf {E}}_{fake}$ is the input embeddings of fake news detection task, and key matrix ${\\rm \\textbf {K}}_{shared}$ and value matrix ${\\rm \\textbf {V}}_{shared}$ are the projections of shared features ${\\rm \\textbf {H}}_{shared}$. Formally, the attention sharing cell can be formalized as follows:\nwhere the dimensions of ${\\rm \\textbf {E}}_{fake}$, ${\\rm \\textbf {K}}_{shared}$, and ${\\rm \\textbf {V}}_{shared}$ are all $\\mathbb {R}^{l\\times (d_p+d_w)}$. The dimensions of remaining parameters in Eqs.(DISPLAY_FORM16, DISPLAY_FORM17) are the same as in Eqs.(DISPLAY_FORM10, DISPLAY_FORM11). Moreover, in order to guarantee the diversity of focused shared features, the number of heads $h$ should not be set too large. Experiments show that our method performs the best performance when $h$ is equal to 2.\nIntegration of the Two Cells We first convert the output of the two cells to vectors ${\\rm \\textbf {G}}$ and ${\\rm \\textbf {A}}$, respectively, and then integrate the vectors in full by the absolute difference and element-wise product BIBREF35.\nwhere $\\odot $ denotes element-wise multiplication and $;$ denotes concatenation.\nThere are two reasons why we adopt single-gate mechanism. One is that transformer encoder in shared layer can efficiently capture the features of long-range dependencies. The features do not need to capture repeatedly by multiple complex gate mechanisms of LSTM and GRU. The other is that single-gate mechanism is more convenient for training (Srivastava et al., 2015).",

        "evidence": "Neural machine translation has recently achieved impressive results BIBREF0 , BIBREF1 , while learning from raw, sentence-aligned parallel text and using little in the way of external linguistic information. However, we hypothesize that various levels of linguistic annotation can be valuable for neural machine translation. Lemmatisation can reduce data sparseness, and allow inflectional variants of the same word to explicitly share a representation in the model. Other types of annotation, such as parts-of-speech (POS) or syntactic dependency labels, can help in disambiguation. In this paper we investigate whether linguistic information is beneficial to neural translation models, or whether their strong learning capability makes explicit linguistic features redundant.\nLet us motivate the use of linguistic features using examples of actual translation errors by neural MT systems. In translation out of English, one problem is that the same surface word form may be shared between several word types, due to homonymy or word formation processes such as conversion. For instance, close can be a verb, adjective, or noun, and these different meanings often have distinct translations into other languages. Consider the following English INLINEFORM0 German example:\nFor the English source sentence in Example SECREF4 (our translation in Example SECREF5 ), a neural MT system (our baseline system from Section SECREF4 ) mistranslates close as a verb, and produces the German verb schließen (Example SECREF6 ), even though close is an adjective in this sentence, which has the German translation nah. Intuitively, part-of-speech annotation of the English input could disambiguate between verb, noun, and adjective meanings of close.\nAs a second example, consider the following German INLINEFORM0 English example:\nGerman main clauses have a verb-second (V2) word order, whereas English word order is generally SVO. The German sentence (Example UID7 ; English reference in Example UID8 ) topicalizes the predicate gefährlich 'dangerous', putting the subject die Route 'the route' after the verb. Our baseline system (Example UID9 ) retains the original word order, which is highly unusual in English, especially for prose in the news domain. A syntactic annotation of the source sentence could support the attentional encoder-decoder in learning which words in the German source to attend (and translate) first.\nWe will investigate the usefulness of linguistic features for the language pair German INLINEFORM0 English, considering the following linguistic features:\nThe inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form. The other linguistic features are motivated by disambiguation, as discussed in our introductory examples.\nWe will investigate the usefulness of linguistic features for the language pair German↔English, considering the following linguistic features: The inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form.",

        "answer": "Goodness scoring measures.",
        "evidence": "Major progress has been made in different tasks in Natural Language Processing, yet our models are still not able to describe why they make their decisions when summarizing an article, translating a sentence, or answering a question. Lack of meta information (e.g. general world knowledge regarding the task) is one important obstacle in the construction of language understanding models capable of reasoning about their considerations when making decisions (predictions).\nWikipedia is a great resource of world knowledge for human beings, but lacks the proper structure to be useful for the models. To address this issue and make a more structured knowledge-base, we are trying to structure Wikipedia. The final goal is to have, for each Wikipedia article, known entities and sets of attributes, with each attribute linking to other entities wherever possible. The initial step towards this goal is to classify the entities into predefined categories and verify the results using human annotators.\nThroughout the past years, many have tried classifying Wikipedia articles into different category sets the majority of which range between 3 to 15 class types BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4. Although useful, such categorization type sets are not much helpful when the classified articles are being used as the training data for Question-Answering systems, since the extracted knowledge-base does not provide detailed enough information to the model.\nOn the other hand, much larger categorization type sets such as Cyc-Taxonomy BIBREF5, Yago-Taxonomy BIBREF6, or Wikipedia's own taxonomy of categories BIBREF7 are not suitable for our task since the tags are not verifiable for annotators. In addition, taxonomies are not designed in a tree format, so some categories might have multiple super-categories and this would make the verification process much harder for the cases that the article is about multiple different topics.\nConsidering the mentioned problem requirements, we believe Extended Named Entities Hierarchy BIBREF8, containing 200 fine-grained categories tailored for Wikipedia articles, is the best fitting tag set.\nHigashinaka et al. higashinaka2012 were the first to use this extended tag set as the categorization output of the dumped Wikipedia pages while using a hand-extracted feature set for converting the pages into their model input vectors. Following their work, Suzuki et al. suzuki2016 modelled the links between different Wikipedia pages as an augmentation to the extracted input features to the classifier. They also proposed a more complex model for learning the mapping between the converted articles and the labels.\nAlthough providing useful insights, none of the works above have considered the multi-lingual nature of many Wikipedia articles. Hence, we decided to hire annotators and educate them on the Extended Named Entities (ENE) tag set to annotate each article with up to 6 different ENE classes, and exploit the Wikipedia language links in the annotated articles to create our multi-lingual Wikipedia classification dataset. Section 2 details our dataset creation process.\nWe then used the two models mentioned above, which are to the best of our knowledge the only works close enough to our task in hand, to benchmark our dataset. Section 3 provides more details about our feature selection method and the models. Section 4 presents our experimental setup and the classification results.\nWe also considered the Goodness scoring measures mentioned in to remove some of the unuseful articles.",

        "evidence": "Vietnamese, like many languages in continental East Asia, is an isolating language and one branch of Mon-Khmer language group. The most basic linguistic unit in Vietnamese is morpheme, similar with syllable or token in English and “hình vị” (phoneme) or “tiếng” (syllable) in Vietnamese. According to the structured rule of its, Vietnamese can have about 20,000 different syllables (tokens). However, there are about 8,000 syllables used the Vietnamese dictionaries. There are three methods to identify morphemes in Vietnamese text BIBREF10 .\nMorpheme is the smallest meaningful unit of Vietnamese.\nMorpheme is the basic unit of Vietnamese.\nMorpheme is the smallest meaningful unit and is not used independently in the syntax factor.\nIn computational linguistics, morpheme is the basic unit of languages as Leonard Bloomfield mentioned for English BIBREF11 . In our research for Vietnamese, we consider the morpheme as syllable, called “tiếng” in Vietnamese (as Nguyen’s definition BIBREF12 ).\nThe next concept in linguistics is word which has fully grammar and meaning function in sentences. For Vietnamese, word is a single morpheme or a group of morphemes, which are fixed and have full meaning BIBREF12 . According to Nguyen, Vietnamese words are able classified into two types, (1) 1- syllable words with fully meaning and (2) n-syllables words whereas these group of tokens are fixed. Vietnamese syllable is not fully meaningful. However, it is also explained in the meaning and structure characteristics. For example, the token “kỳ” in “quốc kỳ” whereas “quốc” means national, “kỳ” means flag. Therefore, “quốc kỳ” means national flag.\nConsider dictionary used for evaluating the corpus, extracting features for models, and evaluating the systems, there are many Vietnamese dictionaries, however we recommend the Vietnamese dictionary of Hoang Phe, so called Hoang Phe Dictionary.

        "question": "What matrixes do the inputs of this cell include?",
        "answer": "The input embeddings of the specific task and the shared features of both tasks.",
        "evidence": "In order to select valuable and appropriate shared features for different tasks, we design a selected sharing layer following the shared layer. The selected sharing layer consists of two cells: gated sharing cell for filtering useless features and attention sharing cell for focusing on valuable shared features for specific tasks. The description of this layer is depicted in Figure FIGREF6 and Figure FIGREF15. In the following, we introduce two cells in details.\nGated Sharing Cell Inspired by forgotten gate mechanism of LSTM BIBREF32 and GRU BIBREF33, we design a single gated cell to filter useless shared features from shared layer. There are two reasons why we adopt single-gate mechanism. One is that transformer encoder in shared layer can efficiently capture the features of long-range dependencies. The features do not need to capture repeatedly by multiple complex gate mechanisms of LSTM and GRU. The other is that single-gate mechanism is more convenient for training BIBREF34. Formally, the gated sharing cell can be expressed as follows:\nwhere ${\\rm \\textbf {H}}_{shared}\\! \\in \\! \\mathbb {R}^{1 \\times l(d_p+d_w)}$ denotes the outputs of shared layer upstream, ${\\rm \\textbf {W}}_{fake} \\in \\mathbb {R}^{l(d_p+d_w) \\times l(d_p+d_w)}$ and ${\\rm \\textbf {b}}_{fake} \\in \\mathbb {R}^{1 \\times l(d_p+d_w)}$ are trainable parameters. $\\sigma $ is a non-linear activation - sigmoid, which makes final choices for retaining and discarding features in shared layer.\nThen the shared features after filtering via gated sharing cell ${\\rm \\textbf {g}}_{fake}$ for the task of fake news detection are represented as:\nwhere $\\odot $ denotes element-wise multiplication.\nSimilarly, for the auxiliary task - the task of stance detection, filtering process in the gated sharing cell is the same as the task of fake news detection, so we do not reiterate them here.\nAttention Sharing Cell To focus on helpful shared features that are beneficial to specific tasks from upstream shared layer, we devise an attention sharing cell based on attention mechanism. Specifically, this cell utilizes input embeddings of the specific task to weight shared features for paying more attention to helpful features. The inputs of this cell include two matrixes: the input embeddings of the specific task and the shared features of both tasks. The basic attention architecture of this cell, the same as shared-private feature extractor, also adopts transformer encoder (the details in subsection SECREF8). However, in this architecture, query matrix and key matrix are not projections of the same matrix, i.e., query matrix ${\\rm \\textbf {E}}_{fake}$ is the input embeddings of fake news detection task, and key matrix ${\\rm \\textbf {K}}_{shared}$ and value matrix ${\\rm \\textbf {V}}_{shared}$ are the projections of shared features ${\\rm \\textbf {H}}_{shared}$. Formally, the attention sharing cell can be formalized as follows:\nwhere the dimensions of ${\\rm \\textbf {E}}_{fake}$, ${\\rm \\textbf {K}}_{shared}$, and ${\\rm \\textbf {V}}_{shared}$ are all $\\mathbb {R}^{l\\times (d_p+d_w)}$. The dimensions of remaining parameters in Eqs.(DISPLAY_FORM16, DISPLAY_FORM17) are the same as in Eqs.(DISPLAY_FORM10, DISPLAY_FORM11). Moreover, in order to guarantee the diversity of focused shared features, the number of heads $h$ should not be set too large. Experiments show that our method performs the best performance when $h$ is equal to 2.\nIntegration of the Two Cells We first convert the output of the two cells to vectors ${\\rm \\textbf {G}}$ and ${\\rm \\textbf {A}}$, respectively, and then integrate the vectors in full by the absolute difference and element-wise product BIBREF35.\nwhere $\\odot $ denotes element-wise multiplication and $;$ denotes concatenation.\nAttention Sharing Cell To focus on helpful shared features that are beneficial to specific tasks from upstream shared layer, we devise an attention sharing cell based on attention mechanism.

        "evidence": "",
        "answer": "Skiing is a fun sport with something for every age and skill level. The measure of \"hard\" in skiing may be subjective but as a general rule of thumb, trails become harder as the steepness or pitch increases, number and type of obstacles increase, the trail is bumpier or is narrower. Changes along these dimensions present new challenges and require a broader array of skills. \n\nA good way to progress along trails is to pick a trail that presents a challenge in one or two dimensions of \"hard\" to learn or refine skills. As you progress, you can increase the challenges along different dimensions. Labelling at ski resorts help with these choices. Trails are generally classified into bunny (easiest or learning greens), green (circle), blue (square), black (diamond) and double black (two diamonds). When you are learning skiing, it's best to get reasonably confident at a color before moving on to the next one. You don't have to be perfect but you have to feel safe as you progress. While colors are broadly useful, they can still be inexact as measures of hardness. Further, your strengths and weaknesses will also play a part in determining how hard a trail is for you personally. Staff at ski resorts can point you to good trails based on your personal comfort. Remember to always ski with a friend !\n\nFor following this plan, you should consider Kirkwood Ski Resort near South Lake Tahoe. Kirkwood has a reputation for some great advanced skiing trails but it presents many good trails for progressive improvement. If this is your first time skiing, a lesson is strongly recommended to learn the basics of keeping yourselves and those around you safe ! \n\nYou can start on the Timber Creek Area where there are a few bunny trails that are perfect for beginners. Funny bunny and School Run offer plenty of gentle practice for a new skier and when you are ready, ski Graduation (cue confetti). Squirrel Ridge and Snowkirk (on the Mountain Village side) are good next steps because they are long gentle greens.\n\nOnce you are feeling confident, Free 'N' Easy and Hole 'N' Wall offer a gentle introduction to blues. Blues at Kirkwood cater to a wide range of skills. The areas around Lower Zachary and Flying Carpet are good next challenges. If you are feeling good on those blues, try the backside with the appropriately named \"Happiness Is\"\n\nIf you've really got it down, it's time to try some black diamonds. Groomed blacks are easier to ski and fresh snow lowers the challenge further. Try Zachary and the trails around it. At this level, each black may offer a different kind of challenge. Hully Gully may have bumps and Lower Olympic is a nice introduction to a bowl.  There are many to choose from !\n\nThe final challenges are the double blacks and the The Wall is well known favorite. There are no dearth of double blacks and off piste trails at Kirkwood for those that have progressed beyond the labelling.\n\nHave fun and stay safe !",

Despite its theoretical foundations, the practical estimation method for the multivariate PNL model is not well developed. We believe that our proposal increases the applicability of SEM-based causal discovery methods and promotes their use in real-world problems.",
        "evidence": "Understanding causal structures of systems is a fundamental question in science and has been studied in various fields such as biology, economics, and social science. While conducting randomized experiments is the most effective way to identify causal structures, it is often impossible for ethical, technical or cost reasons. Therefore, it is important to develop causal discovery methods that infer causal structures from uncontrolled observational data.\nUsing structural equation models (SEMs) is one major approach in causal discovery. In SEMbased methods, causal structures are assumed to follow parameterized causal models and inferred by estimating the parameters from data. An important property of causal SEMs is identifiability that is a theoretical guarantee that true causal structures can be uniquely identifiable if the joint distributions of data are known. Constructing flexible identifiable models and then developing their estimation methods are the main focuses in SEM-based study.\nVarious identifiable SEMs and their estimation methods have been proposed so far. The linear non-Gaussian acyclic model (LiNGAM) is one of the most studied models. In LiNGAM, a causal structure is represented as a directed acyclic graph (DAG) and each effect variable is generated as the linear combination of cause variables followed by an additive unobserved noise that is independent of the causes. There has been proposed an efficient estimation method named DirectLiNGAM. While LiNGAM is a simple and well-studied model, it may suffer from degradation in complex real-world applications due to the linear assumption. The additive noise model (ANM) is proposed as a more flexible model that can handle nonlinear causal relations. In ANM, cause variables are transformed nonlinearly and then added to an unobserved noise independent from the causes. ANM is proved identifiable except for some trivial cases and an estimation method based on regressions, named regression with subsequent independence test (RESIT), is proposed. As a more realistic model, proposed the post-nonlinear (PNL) model inspired by real-world data observation processes. In the PNL model, cause variables are transformed and added to a noise variable in the same manner as ANM and then transformed again by a nonlinear invertible function. The second transformation represents the sensor or measurement distortion, which is frequently encountered in practice. Although the PNL model is one of the most flexible identifiable causal SEMs, which covers ANM and LiNGAM, its estimation methods are not well-developed except the bivariate case. proposed an estimation method of the bivariate PNL model and a causal discovery procedure based on it, named autoencoder-based causal discovery for the PNL model (AbPNL). AbPNL represents the two nonlinearities with neural networks and estimates them by minimizing two loss terms corresponding to two assumptions of the model: the independence of the cause and the noise and the invertibility of the second nonlinearity. The losses are defined as Hilbert-Schmidt independence criterion (HSIC) and a reconstruction loss, respectively, and minimized directly by a stochastic gradient descent method. Given samples of two variables, AbPNL estimates the models of the two candidate causal directions and infer the true direction as the one that fits the model better. While AbPNL is easy to use owing to no assumptions on neural network structures and the straightforward optimization procedure, it is limited to the bivariate cases and cannot be applied to multivariate cases unless an exhaustive search is performed, which is usually infeasible in practice.\nIn this paper, we propose a new method for multivariate nonlinear causal discovery based on the PNL model. First, we extend the estimation of the bivariate PNL model of AbPNL to the multi-cause model with multiple cause variables and a single effect variable. Then, we iterate the multi-cause model estimation to identify the causal order of the variables in the same manner as the ANM case in RESIT. Finally, we prune redundant edges of the causal DAG constructed from the causal order to obtain the true causal structure. We also show the theoretical validity of the proposed procedure in the multivariate PNL model. We apply the proposed method to synthetic and real-world datasets and show its effectiveness.\nIn this paper, we propose a new method for multivariate nonlinear causal discovery based on the\nPNL model.

These newly labeled microposts are used with the microposts labeled in the micropost classification task of our approach (see Section SECREF2: Micropost Classification) and the expectation of the initial keyword to train the model for comparison. The model trained in this way increases AUC by 0.87% for CyberAttack, and by 1.06% for PoliticianDeath; in comparison, our proposed approach increases AUC by 33.42% for PoliticianDeath and by 15.23% for CyberAttack over the baseline presented by BIBREF1).

        "question": "What kind of data do NLG models heavily rely on?",
        "answer": "Annotated training data.",
        "evidence": "Learning natural language generation (NLG) models heavily relies on annotated training data. However, most available datasets are collected in a single language (typically English), which restricts deploying the applications to other languages. In this work, we aim at transferring the supervision of a monolingual NLG dataset to unseen languages, so that we can boost performance for the low-resource settings.\nVarious methods have been proposed over the years to learn universal cross-lingual word embeddings BIBREF0, BIBREF1, BIBREF2 or sentence encoders BIBREF3, BIBREF4, BIBREF5, which tries to encode multilingual texts into a single shared vector space. Despite achieving promising results on cross-lingual classification problems, cross-lingual pre-trained models purposed for NLG tasks remains relatively understudied.\nThe cross-lingual generation problem is challenging due to the following reasons. First, it requires the models to understand multilingual input texts, and generate multilingual target sequences. So both encoder and decoder should be pre-trained together. Second, the many-to-many nature of cross-lingual NLG increases language pairs with the square of the number of languages. Third, the prediction space of cross-lingual NLG is much larger than classification tasks, which makes the knowledge transfer of decoders quite critical.\nPrevious work mainly relies on machine translation (MT) systems to map texts to different languages. The first strand of research directly uses MT in a pipeline manner BIBREF6. For example, the input written in other languages is first translated to English, and fed into the NLG model that is trained by English data. Then the generated English text is translated back to the target language. Another strand of work employs MT to generate pseudo training data for other language pairs that are lack of annotations BIBREF7, BIBREF8. However, such methods have to use multiple MT systems, which renders them suffering from error propagation. Moreover, because the pipeline-based methods do not explicitly share the same parameter space across the languages, we can not directly transfer the task-specific supervision to other low-resource languages.\nIn this paper, we propose a cross-lingual pre-trained model (named as Xnlg) in order to transfer monolingual NLG supervision to other pre-trained languages by fine-tuning. Specifically, Xnlg shares the same sequence-to-sequence model across languages, and is pre-trained with both monolingual and cross-lingual objectives. The model not only learns to understand multilingual input, but also is able to generate specific languages by conditioning on the encoded semantics. Figure FIGREF2 demonstrates how to use Xnlg to perform cross-lingual transfer for downstream tasks. The proposed model enables us to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation. Besides, we explore several fine-tuning strategies to make a compromise between cross-lingual ability and task ability. In addition, we introduce two cross-lingual NLG datasets (i.e., question generation, and abstractive summarization) for evaluation, which includes three languages, namely English, Chinese, and French. Experimental results on the NLG tasks show that Xnlg achieves competitive performance compared with the machine-translation-based pipeline model in zero-shot cross-lingual settings.\nLearning natural language generation (NLG) models heavily relies on annotated training data.",

Over this dataset, we compare the methodology suggested here to those reported by BIBREF1, BIBREF4. As the latter report overall accuracy of their binary prediction, we convert our controversiality estimates to a binary classification by classifying the higher-scored half as controversial, and the lower half as non-controversial.\nDataset II is based on a more recent version of the Wikipedia list of controversial issues (May 2017). As positive examples we take, from this list, all concepts which appear more than 50 times in Wikipedia. This leaves 608 controversial Wikipedia concepts. For negative examples, we follow BIBREF1, BIBREF4 and select a like number of concepts at random. Here too, since each concept only has a binary label, we convert our estimation into a binary classification, and report accuracy.\nDataset III is extracted from 3561 concepts whose Wikipedia pages are under edit protection, assuming that many of them are likely to be controversial. They were then crowd-annotated, with 10 or more annotators per concept. The annotation instructions were: “Given a topic and its description on Wikipedia, mark if this is a topic that people are likely to argue about.”. Average pairwise kappa agreement on this task was 0.532. Annotations were normalized to controversiality scores on an integer scale of 0 - 10. We used this dataset for testing the models trained on Dataset I.\nIn all datasets, to obtain the sentence-level context of the concepts (positive and negative), we randomly select two equal-sized sets of Wikipedia sentences, that explicitly reference these concepts – i.e., that contain a hyperlink to the article titled by the concept. Importantly, in each sentence we mask the words that reference the concept – i.e., the surface form of the hyperlink leading to the concept – by a fixed, singular token, thus focusing solely on the context within which the concepts are mentioned.\nDataset II is based on a more recent version of the Wikipedia list of controversial issues (May 2017).

        "question": "Does the prior work in antisocial behavior have any limitations?",
        "answer": "Yes. Most of them focus on post-hoc identification, which limits their practicality as tools for assisting pre-emptive moderation in conversational domains.",
        "evidence": "“Ché saetta previsa vien più lenta.”\n\n– Dante Alighieri, Divina Commedia, Paradiso\nAntisocial behavior is a persistent problem plaguing online conversation platforms; it is both widespread BIBREF0 and potentially damaging to mental and emotional health BIBREF1, BIBREF2. The strain this phenomenon puts on community maintainers has sparked recent interest in computational approaches for assisting human moderators.\nPrior work in this direction has largely focused on post-hoc identification of various kinds of antisocial behavior, including hate speech BIBREF3, BIBREF4, harassment BIBREF5, personal attacks BIBREF6, and general toxicity BIBREF7. The fact that these approaches only identify antisocial content after the fact limits their practicality as tools for assisting pre-emptive moderation in conversational domains.\nAddressing this limitation requires forecasting the future derailment of a conversation based on early warning signs, giving the moderators time to potentially intervene before any harm is done (BIBREF8 BIBREF8, BIBREF9 BIBREF9, see BIBREF10 BIBREF10 for a discussion). Such a goal recognizes derailment as emerging from the development of the conversation, and belongs to the broader area of conversational forecasting, which includes future-prediction tasks such as predicting the eventual length of a conversation BIBREF11, whether a persuasion attempt will eventually succeed BIBREF12, BIBREF13, BIBREF14, whether team discussions will eventually lead to an increase in performance BIBREF15, or whether ongoing counseling conversations will eventually be perceived as helpful BIBREF16.\nApproaching such conversational forecasting problems, however, requires overcoming several inherent modeling challenges. First, conversations are dynamic and their outcome might depend on how subsequent comments interact with each other. Consider the example in Figure FIGREF2: while no individual comment is outright offensive, a human reader can sense a tension emerging from their succession (e.g., dismissive answers to repeated questioning). Thus a forecasting model needs to capture not only the content of each individual comment, but also the relations between comments. Previous work has largely relied on hand-crafted features to capture such relations—e.g., similarity between comments BIBREF16, BIBREF12 or conversation structure BIBREF17, BIBREF18—, though neural attention architectures have also recently shown promise BIBREF19.\nThe second modeling challenge stems from the fact that conversations have an unknown horizon: they can be of varying lengths, and the to-be-forecasted event can occur at any time. So when is it a good time to make a forecast? Prior work has largely proposed two solutions, both resulting in important practical limitations. One solution is to assume (unrealistic) prior knowledge of when the to-be-forecasted event takes place and extract features up to that point BIBREF20, BIBREF8. Another compromising solution is to extract features from a fixed-length window, often at the start of the conversation BIBREF21, BIBREF15, BIBREF16, BIBREF9. Choosing a catch-all window-size is however impractical: short windows will miss information in comments they do not encompass (e.g., a window of only two comments would miss the chain of repeated questioning in comments 3 through 6 of Figure FIGREF2), while longer windows risk missing the to-be-forecasted event altogether if it occurs before the end of the window, which would prevent early detection.\nIn this work we introduce a model for forecasting conversational events that overcomes both these inherent challenges by processing comments, and their relations, as they happen (i.e., in an online fashion). Our main insight is that models with these properties already exist, albeit geared toward generation rather than prediction: recent work in context-aware dialog generation (or “chatbots”) has proposed sequential neural models that make effective use of the intra-conversational dynamics BIBREF22, BIBREF23, BIBREF24, while concomitantly being able to process the conversation as it develops (see BIBREF25 for a survey).\nIn order for these systems to perform well in the generative domain they need to be trained on massive amounts of (unlabeled) conversational data. The main difficulty in directly adapting these models to the supervised domain of conversational forecasting is the relative scarcity of labeled data: for most forecasting tasks, at most a few thousands labeled examples are available, insufficient for the notoriously data-hungry sequential neural models.\nTo overcome this difficulty, we propose to decouple the objective of learning a neural representation of conversational dynamics from the objective of predicting future events. The former can be pre-trained on large amounts of unsupervised data, similarly to how chatbots are trained. The latter can piggy-back on the resulting representation after fine-tuning it for classification using relatively small labeled data. While similar pre-train-then-fine-tune approaches have recently achieved state-of-the-art performance in a number of NLP tasks—including natural language inference, question answering, and commonsense reasoning (discussed in Section SECREF2)—to the best of our knowledge this is the first attempt at applying this paradigm to conversational forecasting.\nTo test the effectiveness of this new architecture in forecasting derailment of online conversations, we develop and distribute two new datasets. The first triples in size the highly curated `Conversations Gone Awry' dataset BIBREF9, where civil-starting Wikipedia Talk Page conversations are crowd-labeled according to whether they eventually lead to personal attacks; the second relies on in-the-wild moderation of the popular subreddit ChangeMyView, where the aim is to forecast whether a discussion will later be subject to moderator action due to “rude or hostile” behavior. In both datasets, our model outperforms existing fixed-window approaches, as well as simpler sequential baselines that cannot account for inter-comment relations. Furthermore, by virtue of its online processing of the conversation, our system can provide substantial prior notice of upcoming derailment, triggering on average 3 comments (or 3 hours) before an overtly toxic comment is posted.\nTo summarize, in this work we:\nintroduce the first model for forecasting conversational events that can capture the dynamics of a conversation as it develops;\nbuild two diverse datasets (one entirely new, one extending prior work) for the task of forecasting derailment of online conversations;\ncompare the performance of our model against the current state-of-the-art, and evaluate its ability to provide early warning signs.\nOur work is motivated by the goal of assisting human moderators of online communities by preemptively signaling at-risk conversations that might deserve their attention. However, we caution that any automated systems might encode or even amplify the biases existing in the training data BIBREF26, BIBREF27, BIBREF28, so a public-facing implementation would need to be exhaustively scrutinized for such biases BIBREF29.\n\nAntisocial behavior is a persistent problem plaguing online conversation platforms; it is both widespread (Duggan, 2014) and potentially damaging to mental and emotional health (Raskauskas and Stoltz, 2007; Akbulut et al., 2010). The strain this phenomenon puts on community maintainers has sparked recent interest in computational approaches for assisting human moderators. Prior work in this direction has largely focused on post-hoc identification of various kinds of antisocial behavior, including hate speech (Warner and Hirschberg, 2012; Davidson et al., 2017), harassment (Yin et al., 2009), personal attacks (Wulczyn et al., 2017), and general toxicity (Pavlopoulos et al., 2017). The fact that these approaches only identify antisocial content after the fact limits their practicality as tools for assisting pre-emptive moderation in conversational domains.",

        "question": "Why Do We Need GIS?",
        "evidence": "",
        "answer": "GIS use has become mandatory in many settings. GIS are used to fight crime, protect endangered species, reduce pollution, cope with natural disasters, treat epidemics, and improve public health; GIS are instrumental in addressing some of our most pressing societal problems.GIS tools in aggregate save billions of dollars annually in the delivery of goods and services. GIS regularly helps in the day-to-day management of many natural and man-made resources, including sewer, water,power, transportation networks, and package delivery. GIS are at the heart of one of the most important processes in U.S. democracy, decadal redrawing of U.S. congressional districts, and hence the distribution of tax dollars and other government resources.GIS are needed in part because human consumption has reached levels such that many resources, including air and land, replacing substantial limits on human action.The first 100,000 years of human existence caused scant impacts on the world's resources, but in the past 300 years humans have permanently altered most of the Earth's Surface. The atmosphere and oceans exhibit a decreasing ability to benignly absorb carbon dioxide and nitrogen, two of humanity's primary waste products. Silt chokes many rivers, and there are abundant examples of smoke, ozone, or other noxious pollutants substantially harming public health. By the end of the 20th century, most lands south of the boreal region had been farmed, grazed,cut, built over, drained, flooded, or otherwise altered by humans. GIS help us identify and address environmental problems by providing crucial information on where problems occur and who are affected by them. GIS helps us identify the source, location, and extent of adverse environmental impacts, and may help us devise practical plans for monitoring, managing, and mitigating environmental damage.Human impacts on the environment have spurred a strong societal push for the adoption of GIS. Conflicts in resource use,concerns about pollution, and precautions to protect public health have led to legislative mandates that explicitly or implicitly require the consideration of geography. The U.S. Endangered Species Act (ESA) is a good example. The ESA requires adequate protection of rare and threatened organisms. This entails mapping the available habitat and species range and migration patterns, relative to human land use. \nGIS use is mandated in other endeavors, including emergency services, flood protection, disaster assessment and management, and infrastructure development.Public organizations have also adopted GIS because it aids in governmental functions. For example, emergency service vehicles are regularly dispatched and route using GIS. E911 GIS matches the caller's address to the nearest emergency service station, a route is generated based on the streetnetwork and traffic, and emergency crews dispatched in a fraction of the pre-GIS times.Many businesses adopt GIS for increased efficiency in the delivery of goods and services. Retail businesses locate stores based on a number of spatially related factors. Where are the potential customers?What is the spatial distribution of competing businesses? Where are potential new store locations? What are traffic flows near current stores, and how easy is it to park near and access these stores? GIS are also used in hundreds of other business applications, toroute vehicles, guide advertising, design buildings, plan construction, and sell real estate.The societal push to adopt GIS has been complemented by a technological pull in the development and application of GIS. Thousands of lives and untold wealth have been lost because ship captains could not answer the simple question, “Where am I?”Remarkable positioning technologies, generically known as Global Navigation SatelliteSystems (GNSS), are now indispensable tools in commerce, planning, and safety.The technological pull has developed on several fronts. Spatial analysis in particular has been helped by faster computers with more storage, and by the increased interconnectedness via mobile networks. Most real-world spatial problems were beyond the scope of all but the largest organization until the 1990s. GIS computing expenses are becoming an afterthought as costs decrease and performance increases at dizzying rates. Powerful field computers are lighter, faster,more capable, and less expensive, so spatial data display and analysis capabilities may always be at hand.In addition to the computing improvements and the development of GNSS, current “cameras” deliver amazingly detailed aerial and satellite images. Initially,advances in image collection and interpretation were spurred by World War II and then the Cold War because accurate maps were required, but unavailable.Turned toward peacetime endeavors, imaging technologies now help us map food and fodder, houses and highways, and most other natural and human-built objects. Images may be rapidly converted to accurate spatial information over broad areas. Many techniques have been developed for extracting information from image data, and also for ensuring this information faithfully represents the location, shape, and characteristics of features on the ground. Visible light,laser, thermal, and radar scanners are currently being developed to further increase the speed and accuracy with which we map our world. Thus, advances in these three key technologies — imaging, GNSS, and computing — have substantially aided the development of GIS.",

In order to put the numbers in perspective, we also show the results for five increasingly competitive baselines.\nFirst, there is a random baseline, followed by an SVM classifier based on a bag-of-words representation with TF.IDF weights learned on the training data. Then come three versions of the ClaimBuster system: CB-Platform uses scores from the online demo, which we accessed on December 20, 2016, and SVM$_{CBfeat}$ and FNN$_{CBfeat}$ are our re-implementations, trained on our dataset.\nWe can see that all systems perform well above the random baseline. The three versions of ClaimBuster also outperform the TF.IDF baseline on most measures. Moreover, our reimplementation of ClaimBuster performs better than the online platform in terms of MAP. This is expected as their system is trained on a different dataset and it may suffer from testing on slightly out-of-domain data. At the same time, this is reassuring for our implementation of the features, and allows for a more realistic comparison to the ClaimBuster system.\nMore importantly, both the SVM and the FNN versions of our system consistently outperform all three versions of ClaimBuster on all measures. This means that the extra information coded in our model, mainly more linguistic, structural, and contextual features, has an important contribution to the overall performance.\nWe can further see that the neural network model, FNN$_{All}$, clearly outperforms the SVM model: consistently on all measures. As an example, with the precision values achieved by FNN$_{All}$, the system would rank on average 4 positive examples in the list of its top-5 choices, and also 14-15 in the top-20 list. Considering the recall at the first $R$ sentences, we will be able to encounter 43% of the total number of check-worthy sentences.

        "evidence": "Datasets. We perform our experiments with two predetermined event categories: cyber security (CyberAttack) and death of politicians (PoliticianDeath). These event categories are chosen as they are representative of important event types that are of interest to many governments and companies. The need to create our own dataset was motivated by the lack of public datasets for event detection on microposts. The few available datasets do not suit our requirements. For example, the publicly available Events-2012 Twitter dataset BIBREF20 contains generic event descriptions such as Politics, Sports, Culture etc. Our work targets more specific event categories BIBREF21. Following previous studies BIBREF1, we collect event-related microposts from Twitter using 11 and 8 seed events (see Section SECREF2) for CyberAttack and PoliticianDeath, respectively. Unlabeled microposts are collected by using the keyword `hack' for CyberAttack, while for PoliticianDeath, we use a set of keywords related to `politician' and `death' (such as `bureaucrat', `dead' etc.) For each dataset, we randomly select 500 tweets from the unlabeled subset and manually label them for evaluation. Table TABREF25 shows key statistics from our two datasets.\nComparison Methods. To demonstrate the generality of our approach on different event detection models, we consider Logistic Regression (LR) BIBREF1 and Multilayer Perceptron (MLP) BIBREF2 as the target models. As the goal of our experiments is to demonstrate the effectiveness of our approach as a new model training technique, we use these widely used models. Also, we note that in our case other neural network models with more complex network architectures for event detection, such as the bi-directional LSTM BIBREF17, turn out to be less effective than a simple feedforward network. For both LR and MLP, we evaluate our proposed human-AI loop approach for keyword discovery and expectation estimation by comparing against the weakly supervised learning method proposed by BIBREF1 (BIBREF1) and BIBREF17 (BIBREF17) where only one initial keyword is used with an expectation estimated by an individual expert.\nParameter Settings. We empirically set optimal parameters based on a held-out validation set that contains 20% of the test data. These include the hyperparamters of the target model, those of our proposed probabilistic model, and the parameters used for training the target model. We explore MLP with 1, 2 and 3 hidden layers and apply a grid search in 32, 64, 128, 256, 512 for the dimension of the embeddings and that of the hidden layers. For the coefficient of expectation regularization, we follow BIBREF6 (BIBREF6) and set it to $\\lambda =10 \\times $ #labeled examples. For model training, we use the Adam BIBREF22 optimization algorithm for both models.\nEvaluation. Following BIBREF1 (BIBREF1) and BIBREF3 (BIBREF3), we use accuracy and area under the precision-recall curve (AUC) metrics to measure the performance of our proposed approach. We note that due to the imbalance in our datasets (20% positive microposts in CyberAttack and 27% in PoliticianDeath), accuracy is dominated by negative examples; AUC, in comparison, better characterizes the discriminative power of the model.\nCrowdsourcing. We chose Level 3 workers on the Figure-Eight crowdsourcing platform for our experiments. The inter-annotator agreement in micropost classification is taken into account through the EM algorithm. For keyword discovery, we filter keywords based on the frequency of the keyword being selected by the crowd. In terms of cost-effectiveness, our approach is motivated from the fact that crowdsourced data annotation can be expensive, and is thus designed with minimal crowd involvement. For each iteration, we selected 50 tweets for keyword discovery and 50 tweets for micropost classification per keyword. For a dataset with 80k tweets (e.g., CyberAttack), our approach only requires to manually inspect 800 tweets (for 8 keywords), which is only 1% of the entire dataset.\nFor each dataset, we randomly select 500 tweets from the unlabeled subset and manually label them for evaluation.",

It is part of Northern Virginia and borders both the city of Alexandria and Arlington County and forms part of the suburban ring of Washington, D.C. The county is predominantly suburban in character with some urban and rural pockets.\n\nAs of the 2020 census, the population was 1,150,309, making it Virginia's most populous jurisdiction, with around 13% of the Commonwealth's population. The county is also the most populous jurisdiction in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area, with around 20% of the MSA population, as well as the larger Washington-Baltimore-Arlington, DC-MD-VA-WV-PA Combined Statistical Area, with around 13% of the CSA population. The county seat is Fairfax, although because it is an independent city under Virginia law, the city of Fairfax is not part of Fairfax County.\n\nFairfax was the first U.S. county to reach a six-figure median household income and has the third-highest median household income of any county-level local jurisdiction in the U.S. Fairfax County, as part of the Washington, D.C. metropolitan area, is usually included atop or near the top of lists of the wealthiest areas in the United States.\n\nThe county is home to the headquarters of several intelligence agencies such as the Central Intelligence Agency, National Geospatial-Intelligence Agency, National Reconnaissance Office, National Counterterrorism Center, and Office of the Director of National Intelligence as well as the headquarters of several aerospace manufacturing and defense industry giants.

        "answer": "In this day and age when many are busy with work, family, electronic gadgets, social media it becomes increasingly challenging to find the time to exercise.  Staying healthy will allow you to enjoy those distractions longer, but jokes aside it will make you feel energized, motivated and bring out the best in you.  When new discoveries in scenic areas are correctly applied, you don’t need to spend multiple hours at the gym, you don’t have to starve to achieve your goals, this concept was very enticing to me when I first learnt about the Sprint 8 program at my local gym.  I decided to give this a try!\n\nSprint 8 - Its a 20 minute routine, where you spend the first 30 seconds working out at the highest level of intensity (go all out) followed by 90 seconds of active recovery, repeat this 8 times..  You can use a bike, treadmill, elliptical whichever suits your style.  In all my life of being fairly active, Sprint 8 has the toughest workout, but over a year I could see significant results.  I was able to run faster, lower blood pressure, reduce fat percentage, and improve muscle mass.  The key differentiator about this program is that it engages all the three muscle fiber types and releases exercise induced growth hormones to help your body become stronger, leaner and healthier.\n\nAnother advantage is that this program really reduces any change of injury that one may face by running, heavy weight lifting etc therefore allowing you to sustain the exercise program for years to come.  \n\nGive this a try and gain the benefits of efficient exercising.",

        "evidence": "",
        "answer": "For organizations to achieve the most value from their data, they must establish a data foundation that allows for high-quality reporting on past events. Establishing a Databrick’s Lakehouse foundation requires no AI/ML capabilities. Then, over time, use that data AI/ML to drive automated decisions for crucial business processes.  For this reason, there is a direct correlation between the “value curve” for both data and intelligent automation. \nThe value maturity curve for intelligent automation starts with basic, attended, or unattended automation that mimics basic human processes today. Then, as you mature your Robotic Process Automation (RPA) program, your automation(s) need to expand to include simple document understanding AI.  Extracting data from the same form hundreds or thousands of times is a good example. Finally, for any organization to gain the highest value and ROI for their intelligent automation investments, using complex AI/ML to produce automated decisions for digital workers (unattended automation) enables exceptionally complex, long-running automation to be successfully developed, put into production, and maintained over time.\n\nIn summary, think of “AI/ML” as the thinking and “Intelligent Automation” as the doing. The value of both Data and RPA to any organization grows exponentially over time as they develop their ability to apply to complex AI/ML such that those models deliver trusted automated decisions to the digital workforce running complex automation.",

        "question": "What does a good explanation mean for a prototype-based approach?",
        "answer": "In the prototype-based explanation method, an explanation is given in terms of distance and prototype. A good explanation consists of human-interpretable or human-understandable distance and a prototype that can represent a data set. Since we deal with distances in a latent space, the interpretability of a latent space is the most important factor influencing the explanation. This is because the interpretability of a latent space leads to the interpretability of the distance. Therefore, we show the interpretability of the latent space with Figure.3 and Table.1.",
        "evidence": "Our method increases the reliability of the explanation through distance and the prototypes. As noted in, the interpretation of previous prototype-based classification methods is difficult because only the Euclidean distance between prototypes and latent representations is given, while having a similar latent representation does not guarantee that images share similarities in human-interpretable features. Therefore, by sampling with distributions and regularizing latent space through VAE, our model constructs dense explanation space that ensures similar latent representations share similarities in appearance. Figure makes this more evident. Looking at the visualized latent space by t-SNE (Van der, embedded data by the previous method tends to separate clusters, often make the case that the distance between two points in the same class farther than the distance between two different class points, as shown in Figure(a). In contrast, the proposed model increases the reliability of explanation through distance by showing that each class is clustered together and exist close to each other that forms dense latent space. Furthermore, by showing latent representations contained within the prototype distribution d i as images, the prototype's reliability can also be increased by their similarities. As illustrated in Figure(d), features within the distribution are similar to the prototype µ i at basic explanation, demonstrating that prototypes are not coincidentally chosen.\nWe made quantitative comparisons through user study as well as qualitative comparisons to ensure the reliability of the explanation space. We measured the user's understanding through an interactive reconstruction experiment to show the reliability of the explanation space of our method. This experiment is to generate an image similar to a randomly sampled image by changing each dimension value of the latent space through a slide using the decoder of the models. As the user explores the latent space and generates an image similar to the sampled image, we can see how the configuration of the latent space is easy to understand for the user.

The success rate by model is shown in Table.\nDetailed settings for experiments are in Appendix A.2. As concluded that a higher success rate on interactive reconstruction tasks shows improved interpretability, we concluded that the explanation space by our method improved interpretability because the success rate obtained through the interactive reconstruction experiment showed a higher value than the baseline model.

        "answer": "They use a long short-term memory (LSTM) encoder to embed the question and extract embeddings for questions, predicates and entities purely from their character-level representations.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nFirst, we use a long short-term memory (LSTM) encoder to embed the question.Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations.",

        "evidence": "The Battle of the Bulge, also known as the Ardennes Offensive, was the last major German offensive campaign on the Western Front during World War II. The battle lasted for five weeks from 16 December 1944 to 28 January 1945, towards the end of the war in Europe. It was launched through the densely forested Ardennes region between Belgium and Luxembourg. It overlapped with the Alsace Offensive, subsequently the Colmar Pocket, another series of battles launched by the Germans in support of the Ardennes thrust.\n\nThe primary military objectives were to deny further use of the Belgian Port of Antwerp to the Allies and to split the Allied lines, which potentially could have allowed the Germans to encircle and destroy the four Allied forces. The Nazi dictator Adolf Hitler, who since December 1941 had assumed direct command of the German army, believed that achieving these objectives would compel the Western Allies to accept a peace treaty in the Axis powers' favor. By this time, it was palpable to virtually the entire German leadership including Hitler himself that they had no realistic hope of repelling the imminent Soviet invasion of Germany unless the Wehrmacht was able to concentrate the entirety of its remaining forces on the Eastern Front, which in turn obviously required that hostilities on the Western and Italian Fronts be terminated. The Battle of the Bulge remains among the most important battles of the war, as it marked the last major offensive attempted by the Axis Powers on the Western front. After their defeat, Germany would retreat for the remainder of the war.\n\nThe Germans achieved a total surprise attack on the morning of 16 December 1944, due to a combination of Allied overconfidence, preoccupation with Allied offensive plans, and poor aerial reconnaissance due to bad weather. American forces bore the brunt of the attack. The Germans attacked a weakly defended section of the Allied line, taking advantage of heavily overcast weather conditions that grounded the Allies' superior air forces. Fierce American resistance on the northern shoulder of the offensive, around Elsenborn Ridge, and in the south, around Bastogne, blocked German access to key roads to the northwest and west that they counted on for success. Columns of armor and infantry that were supposed to advance along parallel routes found themselves on the same roads. This congestion, and terrain that favored the defenders, threw the German advance behind schedule and allowed the Allies to reinforce the thinly placed troops.\n\nThe farthest west the offensive reached was the village of Foy-Nôtre-Dame, south east of Dinant, being stopped by the U.S. 2nd Armored Division on 24 December 1944. Improved weather conditions from around 24 December permitted air attacks on German forces and supply lines, which sealed the failure of the offensive. On 26 December the lead element of Patton's U.S. Third Army reached Bastogne from the south, ending the siege. Although the offensive was effectively broken by 27 December, when the trapped units of 2nd Panzer Division made two break-out attempts with only partial success, the battle continued for another month before the front line was effectively restored to its position prior to the attack. In the wake of the defeat, many experienced German units were out of men and equipment, and the survivors retreated to the Siegfried Line.\n\nThe Germans' initial attack involved around 410,000 men; just over 1,400 tanks, tank destroyers, and assault guns; 2,600 artillery pieces; and over 1,000 combat aircraft, as well as large numbers of other armored fighting vehicles (AFVs). These were reinforced a couple of weeks later, bringing the offensive's total strength to around 450,000 troops, and 1,500 tanks and assault guns. Between 63,222 and 103,900 of these men were killed, missing, wounded in action, or captured. The battle severely depleted Germany's armored forces, which remained largely unreplaced throughout the remainder of the war.

        "answer": "• The Battle of the Bulge, also known as the Ardennes Offensive, was the last major German offensive campaign on the Western Front during World War II.\n• The battle lasted for five weeks from 16 December 1944 to 28 January 1945, towards the end of the war in Europe.\n• The primary military objectives were to deny further use of the Belgian Port of Antwerp to the Allies and to split the Allied lines, which potentially could have allowed the Germans to encircle and destroy the four Allied forces.\n• The Germans achieved a total surprise attack on the morning of 16 December 1944, due to a combination of Allied overconfidence, preoccupation with Allied offensive plans, and poor aerial reconnaissance due to bad weather.\n• The farthest west the offensive reached was the village of Foy-Nôtre-Dame, south east of Dinant, being stopped by the U.S. 2nd Armored Division on 24 December 1944.\n• On 26 December the lead element of Patton's U.S. Third Army reached Bastogne from the south, ending the siege.\n• The battle severely depleted Germany's armored forces, which remained largely unreplaced throughout the remainder of the war.\n• The \"Bulge\" was the largest and bloodiest single battle fought by the United States in World War II and the third-deadliest campaign in American history.",

        "answer": "To control important aspects of the generated summary at test time.",
        "evidence": "The proliferation of opinions expressed in online reviews, blogs, internet forums, and social media has created a pressing need for automated systems which enable customers, companies, or service providers to make informed decisions without having to absorb large amounts of opinionated text. Opinion summarization is the task of automatically generating summaries for a set of opinions about a specific target BIBREF0. Figure FIGREF1 shows various reviews about the movie “Coach Carter” and example summaries generated by humans and automatic systems. The vast majority of previous work BIBREF1 views opinion summarization as the final stage of a three-step process involving: (1) aspect extraction (i.e., finding features pertaining to the target of interest, such as battery life or sound quality); (2) sentiment prediction (i.e., determining the sentiment of the extracted aspects); and (3) summary generation (i.e., presenting the identified opinions to the user). Textual summaries are created following mostly extractive methods which select representative segments (usually sentences) from the source text BIBREF2, BIBREF3, BIBREF4, BIBREF5. Despite being less popular, abstractive approaches seem more appropriate for the task at hand as they attempt to generate summaries which are maximally informative and minimally redundant without simply rearranging passages from the original opinions BIBREF6, BIBREF7, BIBREF8, BIBREF9. General-purpose summarization approaches have recently shown promising results with end-to-end models which are data-driven and take advantage of the success of sequence-to-sequence neural network architectures. Most approaches BIBREF10, BIBREF11, BIBREF12, BIBREF13 encode documents and then decode the learned representations into an abstractive summary, often by attending to the source input BIBREF14 and copying words from it BIBREF15. Under this modeling paradigm, it is no longer necessary to identify aspects and their sentiment for the opinion summarization task, as these are learned indirectly from training data (i.e., sets of opinions and their corresponding summaries). These models are usually tested on domains where the input is either one document or a small set of documents. However, the number of opinions tends to be very large (150 for the example in Figure FIGREF1). It is therefore practically unfeasible to train a model in an end-to-end fashion, given the memory limitations of modern hardware. As a result, current approaches BIBREF16, BIBREF17, BIBREF18, BIBREF19 sacrifice end-to-end elegance in favor of a two-stage framework which we call Extract-Abstract: an extractive model first selects a subset of opinions and an abstractive model then generates the summary while conditioning on the extracted subset (see Figure FIGREF5). The extractive pass unfortunately has two drawbacks. Firstly, on account of having access to a subset of opinions, the summaries can be less informative and inaccurate, as shown in Figure FIGREF1. And secondly, user preferences cannot be easily taken into account (e.g., the reader may wish to obtain a summary focusing on the acting or plot of a movie as opposed to a general-purpose summary) since more specialized information might have been removed.\nIn this paper, we propose Condense-Abstract, an alternative two-stage framework which uses all input documents when generating the summary (see Figure FIGREF5). We view the opinion summarization problem as an instance of multi-source transduction BIBREF20; we first represent the input documents as multiple encodings, aiming to condense their meaning and distill information relating to sentiment and various aspects of the target being reviewed. These condensed representations are then aggregated using a multi-source fusion module based on which an opinion summary is generated using an abstractive model. We also introduce a zero-shot customization technique allowing users to control important aspects of the generated summary at test time. Our approach enables controllable generation while leveraging the full spectrum of opinions available for a specific target. We perform experiments on a dataset consisting of movie reviews and opinion summaries elicited from the Rotten Tomatoes website (BIBREF16; see Figure FIGREF1). Our framework outperforms state-of-the-art models by a large margin using automatic metrics and in a judgment elicitation study. We also verify that our zero-shot customization technique can effectively generate need-specific summaries.\nWe also introduce a zero-shot customization technique allowing users to control important aspects of the generated summary at test time.",

QE research has grown increasingly popular due to the improved quality of MT systems, and potential for reductions in post-editing time and the corresponding savings in labor costs BIBREF2 , BIBREF3 . QE can be performed on multiple granularities, including at word level, sentence level, or document level. In this paper, we focus on quality estimation at word level, which is framed as the task of performing binary classification of translated tokens, assigning “OK” or “BAD” labels.\nEarly work on this problem mainly focused on hand-crafted features with simple regression/classification models BIBREF4 , BIBREF5 . Recent papers have demonstrated that utilizing recurrent neural networks (RNN) can result in large gains in QE performance BIBREF6 . However, these approaches encode the context of the target word by merely concatenating its left and right context words, giving them limited ability to control the interaction between the local context and the target word.\nIn this paper, we propose a neural architecture, Context Encoding Quality Estimation (CEQE), for better encoding of context in word-level QE. Specifically, we leverage the power of both (1) convolution modules that automatically learn local patterns of surrounding words, and (2) hand-crafted features that allow the model to make more robust predictions in the face of a paucity of labeled data. Moreover, we further utilize stacked recurrent neural networks to capture the long-term dependencies and global context information from the whole sentence.\nWe tested our model on the official benchmark of the WMT18 word-level QE task.

        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nOur hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences.

At the end of the turn, you want to bring your feet forward and aim to have at least half of the pressure just in front of the heel of the foot, this will allow the edge along the tail of the ski to bite into the snow.\n\nIf you have too much pressure on the uphill foot, for example, you are leaning up the hill or transferred your weight too early onto the new downhill foot, that can also cause your current downhill foot to not get enough grip and washout.

Yoga, Vaisheshika, Vedanta and Nyaya schools of Hinduism discuss Ishvara, but assign different meanings.\n\nEarly Nyaya school scholars considered the hypothesis of a deity as a creator God with the power to grant blessings, boons and fruits; but these early Nyaya scholars then rejected this hypothesis, and were non-theistic or atheists.

        "answer": "No.",
        "evidence": "The task of speculation detection and scope resolution is critical in distinguishing factual information from speculative information. This has multiple use-cases, like systems that determine the veracity of information, and those that involve requirement analysis. This task is particularly important to the biomedical domain, where patient reports and medical articles often use this feature of natural language. This task is commonly broken down into two subtasks: the first subtask, speculation cue detection, is to identify the uncertainty cue in a sentence, while the second subtask: scope resolution, is to identify the scope of that cue. For instance, consider the example:\nIt might rain tomorrow.\nThe speculation cue in the sentence above is ‘might’ and the scope of the cue ‘might’ is ‘rain tomorrow’. Thus, the speculation cue is the word that expresses the speculation, while the words affected by the speculation are in the scope of that cue.\nThis task was the CoNLL-2010 Shared Task (BIBREF0), which had 3 different subtasks. Task 1B was speculation cue detection on the BioScope Corpus, Task 1W was weasel identification from Wikipedia articles, and Task 2 was speculation scope resolution from the BioScope Corpus. For each task, the participants were provided the train and test set, which is henceforth referred to as Task 1B CoNLL and Task 2 CoNLL throughout this paper.\nFor our experimentation, we use the sub corpora of the BioScope Corpus (BIBREF1), namely the BioScope Abstracts sub corpora, which is referred to as BA, and the BioScope Full Papers sub corpora, which is referred to as BF. We also use the SFU Review Corpus (BIBREF2), which is referred to as SFU.\nThis subtask of natural language processing, along with another similar subtask, negation detection and scope resolution, have been the subject of a body of work over the years. The approaches used to solve them have evolved from simple rule-based systems (BIBREF3) based on linguistic information extracted from the sentences, to modern deep-learning based methods. The Machine Learning techniques used varied from Maximum Entropy Classifiers (BIBREF4) to Support Vector Machines (BIBREF5,BIBREF6,BIBREF7,BIBREF8), while the deep learning approaches included Recursive Neural Networks (BIBREF9,BIBREF10), Convolutional Neural Networks (BIBREF11) and most recently transfer learning-based architectures like Bidirectional Encoder Representation from Transformers (BERT) (BIBREF12). Figures FIGREF1 and FIGREF1 contain a summary of the papers addressing speculation detection and scope resolution (BIBREF13, BIBREF5, BIBREF9, BIBREF3, BIBREF14, BIBREF15, BIBREF16, BIBREF17, BIBREF6, BIBREF11, BIBREF18, BIBREF10, BIBREF19, BIBREF7, BIBREF4, BIBREF8).\nInspired by the most recent approach of applying BERT to negation detection and scope resolution (BIBREF12), we take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT (BIBREF20), XLNet (BIBREF21) and RoBERTa (BIBREF22), applied to speculation detection and scope resolution. We evaluate the performance of each model across all datasets via the single dataset training approach, and report all scores including inter-dataset scores (i.e. train on one dataset, evaluate on another) to test the generalizability of the models. This approach outperforms all existing systems on the task of speculation detection and scope resolution. Further, we jointly train on multiple datasets and obtain improvements over the single dataset training approach on most datasets.\nContrary to results observed on benchmark GLUE tasks, we observe XLNet consistently outperforming RoBERTa. To confirm this observation, we apply these models to the negation detection and scope resolution task, and observe a continuity in this trend, reporting state-of-the-art results on three of four datasets on the negation scope resolution task.\nThe rest of the paper is organized as follows: In Section 2, we provide a detailed description of our methodology and elaborate on the experimentation details. In Section 3, we present our results and analysis on the speculation detection and scope resolution task, using the single dataset and the multiple dataset training approach. In Section 4, we show the results of applying XLNet and RoBERTa on negation detection and scope resolution and propose a few reasons to explain why XLNet performs better than RoBERTa. Finally, the future scope and conclusion is mentioned in Section 5.\nInspired by the most recent approach of applying BERT to negation detection and scope resolution, we take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT, XLNet and RoBERTa, applied to speculation detection and scope resolution.",

        "evidence": "A Chianti wine (/kiˈænti/, also US: /-ˈɑːn-/, Italian: [ˈkjanti]) is any wine produced in the Chianti region of central Tuscany. It was historically associated with a squat bottle enclosed in a straw basket, called a fiasco (\"flask\"; pl. fiaschi). However, the fiasco is only used by a few makers of the wine as most Chianti is now bottled in more standard shaped wine bottles. In the mid-late 19th century, Baron Bettino Ricasoli (later Prime Minister of the Kingdom of Italy) helped establish Sangiovese as the blend's dominant grape variety, creating the blueprint for today's Chianti wines.\n\nThe first definition of a wine area called Chianti was made in 1716. It described the area near the villages of Gaiole, Castellina and Radda; the so-called Lega del Chianti and later Provincia del Chianti (Chianti province). In 1932 the Chianti area was completely redrawn and divided into seven sub-areas: Classico, Colli Aretini, Colli Fiorentini, Colline Pisane, Colli Senesi, Montalbano and Rùfina. Most of the villages that in 1932 were added to the newly defined Chianti Classico region added in Chianti to their names, for example Greve in Chianti, which amended its name in 1972. Wines labelled Chianti Classico come from the largest sub-area of Chianti, which includes the original Chianti heartland. Only Chianti from this sub-zone may display the black rooster (gallo nero) seal on the neck of the bottle, which indicates that the producer of the wine is a member of the Chianti Classico Consortium, the local association of producers. Other variants, with the exception of Rufina north-east of Florence and Montalbano south of Pistoia, originate in the named provinces: Siena for the Colli Senesi, Florence for the Colli Fiorentini, Arezzo for the Colli Aretini and Pisa for the Colline Pisane. In 1996 part of the Colli Fiorentini sub-area was renamed Montespertoli.\n\nDuring the 1970s producers started to reduce the quantity of white grapes in Chianti. In 1995 it became legal to produce a Chianti with 100% Sangiovese. For a wine to retain the name of Chianti it must be produced with at least 80% Sangiovese grapes. Aged Chianti (38 months instead of 4–7) may be labelled as Riserva. Chianti that meets more stringent requirements (lower yield, higher alcohol content and dry extract) may be labelled as Chianti Superiore, although Chianti from the Classico sub-area is not allowed in any event to be labelled as Superiore.",

        "answer": "Egyptian pyramids are fascinating ancient buildings edified more than 2500 years before the Common Era. According to Egyptologists, these megalithic structures served as tombs for the biggest pharaohs that successively ruled the region in that Era. The biggest ones, present until now in Giza, are built with astonishing precision using the rudimental tools and materials that were available at that time. For example, Khufu pyramid, culminating at 481 feet, is an architectural masterpiece. The size, orientation and precision of this pyramid are keeping the best current architects agape. However, the journey was not straightforward for ancient Egyptians. Building such megalithic structures remains very hard to even nowadays. Before achieving the precision of the pyramids on Giza plateau, some inconsistencies and simpler trials are still present in Egypt showing the progressive improvement in their construction know-how through time. The first historically documented pyramid in Egypt is attributed to Djozer pharaoh in the third dynastic period. It is a stepped structure with superposed squares without big attention to the external design and polishment that we find later in the more recent pyramids. Egyptologists proved the existence of many other attempts to build similar structures in the same dynasty. However, the first complete pyramid structures appeared only in the 4th dynasty, giving successively the rise of the great pyramids of Meidum, Dahshur, and Giza",

This could be done by manually annotating spans representing concepts and relations, however, the size of our clusters makes this a huge effort: 2288 sentences per topic (69k in total) need to be processed. Therefore, we resort to an automatic approach.\nThe Open Information Extraction paradigm BIBREF38 offers a representation very similar to the desired one. For instance, from\n\nStudents with bad credit history should not lose hope and apply for federal loans with the FAFSA.\n\nOpen IE systems extract tuples of two arguments and a relation phrase representing propositions:\n\n(s. with bad credit history, should not lose, hope)\n(s. with bad credit history, apply for, federal loans with the FAFSA)\n\nWhile the relation phrase is similar to a relation in a concept map, many arguments in these tuples represent useful concepts. We used Open IE 4, a state-of-the-art system BIBREF39 to process all sentences. After removing duplicates, we obtained 4137 tuples per topic.\nSince we want to create a gold-standard corpus, we have to ensure that we produce high-quality data. We therefore made use of the confidence assigned to every extracted tuple to filter out low quality ones. To ensure that we do not filter too aggressively (and miss important aspects in the final summary), we manually annotated 500 tuples sampled from all topics for correctness. On the first 250 of them, we tuned the filter threshold to 0.5, which keeps 98.7% of the correct extractions in the unseen second half.

        "evidence": "Coffee is a beverage prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It has the highest sales in the world market for hot drinks.\n\nSeeds of the Coffea plant's fruits are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often used to mask the bitter taste or enhance the flavor.\n\nThough coffee is now a global commodity, it has a long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee drinking in the form of the modern beverage appears in modern-day Yemen from the mid-15th century in Sufi shrines, where coffee seeds were first roasted and brewed in a manner similar to current methods. The Yemenis procured the coffee beans from the Ethiopian Highlands via coastal Somali intermediaries and began cultivation. By the 16th century, the drink had reached the rest of the Middle East and North Africa, later spreading to Europe. In the 20th century, coffee became a global commodity, creating different coffee cultures around the world.\n\nThe two most commonly grown coffee bean types are C. arabica and C. robusta. Coffee plants are cultivated in over 70 countries, primarily in the equatorial regions of the Americas, Southeast Asia, the Indian subcontinent, and Africa. As of 2018, Brazil was the leading grower of coffee beans, producing 35% of the world's total. Green, unroasted coffee is traded as an agricultural commodity. Despite sales of coffee reaching billions of dollars worldwide, farmers producing coffee beans disproportionately live in poverty. Critics of the coffee industry have also pointed to its negative impact on the environment and the clearing of land for coffee-growing and water use",

        "evidence": "Our framework combines text-embedding, geometric graph construction and multi-resolution community detection to identify, rather than impose, content-based clusters from free, unstructured text in an unsupervised manner.\nFigure 1 shows a summary of our pipeline. First, we pre-process each document to transform text into consecutive word tokens, where words are in their most normalised forms, and some words are removed if they have no distinctive meaning when used out of context BIBREF5 , BIBREF6 . We then train a paragraph vector model using the Document to Vector (Doc2Vec) framework BIBREF7 on the whole set (13 million) of preprocessed text records, although training on smaller sets (1 million) also produces good results. This training step is only done once. This Doc2Vec model is subsequently used to infer high-dimensional vector descriptions for the text of each of the 3229 documents in our target analysis set. We then compute a matrix containing pairwise similarities between any pair of document vectors, as inferred with Doc2Vec. This matrix can be thought of as a full, weighted graph with documents as nodes and edges weighted by their similarity. We sparsify this graph to the union of a minimum spanning tree and a k-Nearest Neighbors (MST-kNN) graph BIBREF8 , a geometric construction that removes less important similarities but preserves global connectivity for the graph and, hence, for the dataset. The derived MST-kNN graph is analysed with Markov Stability BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , a multi-resolution dynamics-based graph partitioning method that identifies relevant subgraphs (i.e., clusters of documents) at different levels of granularity. MS uses a diffusive process on the graph to reveal the multiscale organisation at different resolutions without the need for choosing a priori the number of clusters, scale or organisation. To analyse a posteriori the different partitions across levels of resolution, we use both visualisations and quantitative scores. The visualisations include word clouds to summarise the main content, graph layouts, as well as Sankey diagrams and contingency tables that capture the correspondences across levels of resolution and relationships to the hand-coded classifications. The partitions are also evaluated quantitatively to score: (i) their intrinsic topic coherence (using pairwise mutual information BIBREF13 , BIBREF14 ), and (ii) their similarity to the operator hand-coded categories (using normalised mutual information BIBREF15 ).

        "question": "How many times does pre-initialization on the public graph speed up the decoding time?",
        "answer": "A factor of three.",
        "evidence": "Speech input is now a common feature for smart devices. In many cases, the user's query involves entities such as a name from a contact list, a location, or a music title. Recognizing entities is particularly challenging for speech recognition because many entities are infrequent or out of the main vocabulary of the system. One way to improve performance is such cases is through the use of a personal language model (LM) which contains the expected user-specific entities. Because each user can have their own personalized LM, it is vital that the speech decoder be able to efficiently load the model on the fly, so it can be used in decoding, without any noticeable increase in latency.\nMany state-of-the-art speech recognition decoders are based on the weighted finite state transducer (WFST) paradigm BIBREF0, BIBREF1. A conventional WFST decoder searches a statically composed $H C L G$ graph, where $H$ is the graph that translates HMM states to CD phones, $C$ translates CD phones to graphemes, $L$ translates graphemes to words and $G$ is graph that represents the language model. Using a statically composed graph has two limitations. First, it is both compute and memory intensive when the vocabulary and LM are large. Second, the static graph approach makes it hard to handle personalized language models BIBREF2. Many common tasks a user may want to perform with a voice assistant such as making phone calls, messaging to a specific contact or playing favorite music require a personalized language model. A dynamic WFST decoder is better suited for such cases. As denoted in Eq (DISPLAY_FORM1), in a dynamic WFST decoder, $HCL$ is composed and optimized offline, while $G$ is composed on the fly with lazy (on-demand) composition, denoted as $\\circ $.\nTo handle dynamic entities, a class LM $G_c$ is normally used as background $G$ and a personalized LM $G_p$ is replaced on-the-fly, before applying lazy composition.\nSince the non-terminal states are composed on-the-fly, it means the states of recognition FST will also contain personalized information that cannot be used by other users or service threads.\nIn previous work, a method was proposed to do a pre-initialized composition for a non-class LM BIBREF3. However, it the dynamic part is still expanded on-the-fly. In this work, we propose two improvements in order to best leverage class language models. First, we use simpler methods for pre-initialization which do not need to pre-generate decoder state statistics. Second, we propose a two-layer pre-initialization mechanism that also avoids performing dynamic expansion on per user basis. In the two-layer pre-initialization method, we make use of a class LM with class tag. We build a personalized FST that contains the members of the class for each user. Using the FST replacement algorithm, we obtain a personalized language transducer BIBREF4. We perform a pre-composition for all FST states whose transitions do not contain class tags. By doing so, the actual on-demand composition is only required for the states in personalized FST. For a multi-threaded service, the pre-composed FST can be shared by all threads, since it does not contain personalized FST states (non-terminals). The personalized part will be shared for all utterances from the same user, which will take full advantage of memory usage.\nUnlike the previous pre-initialization approach that is based on calculating the state statistics BIBREF3, our simplified pre-initialization methods do not rely on pre-calculated state frequencies. Instead, we directly expand the graph with breadth-first search or through a data-driven approach where a small numbers of utterances are processed by the decoder offline. We found that both methods are effective, but the data-driven approach outperforms the breadth first search algorithm. Both methods can be combined to achieve the best performance. Through a series of experiments on a speech recognition task for the calling domain, we found that pre-initialization on the public graph speeds up the decoding time by a factor of three. Futhermore, sharing the private graph further reduces decoding time and results in factor of five improvement in efficiency.\nThrough a series of experiments on a speech recognition task for the calling domain, we found that pre-initialization on the public graph speeds up the decoding time by a factor of three.",

Large news portals often employ moderators, who are frequently overwhelmed by the volume and abusiveness of comments. Readers are disappointed when non-abusive comments do not appear quickly online because of moderation delays. Smaller news portals may be unable to employ moderators, and some are forced to shut down their comments.\nIn previous work BIBREF0 , we introduced a new dataset of approx. 1.6M manually moderated user comments from a Greek sports news portal, called Gazzetta, which we made publicly available. Experimenting on that dataset and the datasets of Wulczyn et al. Wulczyn2017, which contain moderated English Wikipedia comments, we showed that a method based on a Recurrent Neural Network (rnn) outperforms detox BIBREF1 , the previous state of the art in automatic user content moderation. Our previous work, however, considered only the texts of the comments, ignoring user-specific information (e.g., number of previously accepted or rejected comments of each user).

Oligopolies often result from the desire to maximize profits, which can lead to collusion between companies. This reduces competition, increases prices for consumers, and lowers wages for employees.\n\nMany industries have been cited as oligopolistic, including civil aviation, electricity providers, the telecommunications sector, Rail freight markets, food processing, funeral services, sugar refining, beer making, pulp and paper making, and automobile manufacturing.\n\nMost countries have laws outlawing anti-competitive behavior. EU competition law prohibits anti-competitive practices such as price-fixing and manipulating market supply and trade among competitors. In the US, the United States Department of Justice Antitrust Division and the Federal Trade Commission are tasked with stopping collusion. However, corporations can evade legal consequences through tacit collusion, as collusion can only be proven through actual and direct communication between companies.\n\nIt is possible for oligopolies to develop without collusion and in the presence of fierce competition among market participants. This is a situation similar to perfect competition, where oligopolists have their own market structure. In this situation, each company in the oligopoly has a large share in the industry and plays a pivotal, unique role. With post-socialist economies, oligopolies may be particularly pronounced. For example in Armenia, where business elites enjoy oligopoly, 19% of the whole economy is monopolized (BEEPS 2009 database), making it the most monopolized country in the region. ",

There are several methods using textual information to help KG representation learning.\n BIBREF3 represent an entity as the average of its word embeddings in entity name, allowing the sharing of textual information located in similar entity names.\n BIBREF5 jointly embed knowledge and text into the same space by aligning the entity name and its Wikipedia anchor, which brings promising improvements to the accuracy of predicting facts. BIBREF6 extend the joint model and aligns knowledge and words in the entity descriptions. However, these two works align the two kinds of embeddings on word level, which can lose some semantic information on phrase or sentence level.\n BIBREF25 also represent entities with entity names or the average of word embeddings in descriptions. However, their use of descriptions neglects word orders, and the use of entity names struggles with ambiguity. BIBREF7 jointly learn knowledge graph embeddings with entity descriptions. They use continuous bag-of-words and convolutional neural network to encode semantics of entity descriptions. However, they separate the objective functions into two energy functions of structure-based and description-based representations. BIBREF26 embeds both entity and relation embeddings by taking KG and text into consideration using CNN. To utilize both representations, they need further estimate an optimum weight coefficients to combine them together in the specific tasks.\nBesides entity representation, there are also a lot of works BIBREF27 , BIBREF28 , BIBREF29 to map textual relations and knowledge base relations to the same vector space and obtained substantial improvements.\nWhile releasing the current paper we discovered a paper by BIBREF30 proposing a similar model with attention mechanism which is evaluated on link prediction and triplet classification.

        "evidence": "Verb is crucial in sentence understanding BIBREF0 , BIBREF1 . A major issue of verb understanding is polysemy BIBREF2 , which means that a verb has different semantics or senses when collocating with different objects. In this paper, we only focus on verbs that collocate with objects. As illustrated in Example SECREF1 , most verbs are polysemous. Hence, a good semantic representation of verbs should be aware of their polysemy.\nExample 1 (Verb Polysemy) eat has the following senses:\nMany typical verb representations, including FrameNet BIBREF3 , PropBank BIBREF4 , and VerbNet BIBREF5 , describe verbs' semantic roles (e.g. ingestor and ingestibles for “eat”). However, semantic roles in general are too coarse to differentiate a verb's fine-grained semantics. A verb in different phrases can have different semantics but similar roles. In Example SECREF1 , both “eat”s in “eat breakfast” and “eat apple” have ingestor. But they have different semantics.\nThe unawareness of verbs' polysemy makes traditional verb representations unable to fully understand the verb in some applications. In sentence I like eating pitaya, people directly know “pitaya” is probably one kind of food since eating a food is the most fundamental semantic of “eat”. This enables context-aware conceptualization of pitaya to food concept. But by only knowing pitaya's role is the “ingestibles”, traditional representations cannot tell if pitaya is a food or a meal.\nVerb Patterns We argue that verb patterns (available at http://kw.fudan.edu.cn/verb) can be used to represent more fine-grained semantics of a verb. We design verb patterns based on two word collocations principles proposed in corpus linguistics BIBREF6 : idiom principle and open-choice principle. Following the principles, we designed two types of verb patterns.\nAccording to the above definitions, we use verb patterns to represent the verb's semantics. Phrases assigned to the same pattern have similar semantics, while those assigned to different patterns have different semantics. By verb patterns, we know the “pitaya” in I like eating pitaya is a food by mapping “eat pitaya” to “eat $ INLINEFORM0 food”. On the other hand, idiom patterns specify which phrases should not be conceptualized. We list verb phrases from Example SECREF1 and their verb patterns in Table TABREF7 . And we will show how context-aware conceptualization benefits from our verb patterns in the application section.\nThus, our problem is how to generate conceptualized patterns and idiom patterns for verbs. We use two public data sets for this purpose: Google Syntactic N-Grams (http://commondatastorage.googleapis.com/books/syntactic -ngrams/index.html) and Probase BIBREF7 . Google Syntactic N-grams contains millions of verb phrases, which allows us to mine rich patterns for verbs. Probase contains rich concepts for instances, which enables the conceptualization for objects. Thus, our problem is given a verb INLINEFORM0 and a set of its phrases, generating a set of patterns (either conceptualized patterns or idiom patterns) for INLINEFORM1 . However, the pattern generation for verbs is non-trivial. In general, the most critical challenge we face is the trade-off between generality and specificity of the generated patterns, as explained below.\nWe use two public data sets for this purpose: Google Syntactic N-Grams (http://commondatastorage.googleapis.com/books/syntactic -ngrams/index.html) and Probase (Wu et al. 2012).",

The study tested plants in sealed chambers and with highly elevated levels of volatile organic compounds (specifically benzene, trichloroethylene and formaldehyde). It concluded that to the extent that houseplants improve air quality, the mechanism of action is microorganisms within the potting soil, rather than the plants themselves.\n\nHouseplants do have a statistically significant effect on the concentrations of both carbon monoxide and carbon dioxide in normal indoor environments, reducing carbon dioxide levels by 10-25% and carbon monoxide levels by up to 90%.  The effect has been investigated by NASA for use in spacecraft.\n\nPlants also appear to increase the number and diversity of bacteria in homes, while reducing fungal diversity.

In order to make his proposal a surprise, Larry Joe was going to have to do things a little out-of-the-ordinary.\nHis plan was to have a party with all of their friends, swimming in the lake behind his house. Having such a casual party helped reduce any suspicion that The President might have, plus Larry Joe had thrown such parties before. In order to make things special, he bought a dozen bottles of champagne and food for after the proposal. And to make things memorable, he would shout his proposal while flying over the lake on the rope swing! His plan was coming together.\nThe day of the party had arrived and the guests started showing up. The President was wearing her bikini and swam to the floating dock. Larry Joe took his friend Smoochy aside and whispered something in his ear. Everyone was having a good time, enjoying the warm water and cold beverages. But suddenly a low rumble of thunder rolled in from a distance. Larry Joe decided he better make his proposal now. \nHe climbed up on the platform with the rope and yelled, \"it's time for the presidential address!\" This was the code that sent Smoochy running up to the house to retrieve the ring, which had been hidden in the computer desk inside. Larry Joe then leapt off the platform and swung out over the water. He yelled, \"President, will you marry me?\", then dove into the water. At this point, all but the select few friends who knew of the upcoming proposal were caught off guard, most especially The President.\nLarry Joe then swam over to the dock where The President was laying in the sun, and she said, \"is this really happening?\" Larry Joe replied, \"yes!\" He then climbed out of the water as Smoochy came back down the stairs with the ring box in hand. Larry Joe took The President by the hand over to the trees and knelt down in the traditional manner and once more repeated his proposal: \"President, will you marry me?\", then he handed her the ring box.\nNow you must understand that this ring box was quite unique. It had been hand-made by Larry Joe out of wood, in the shape of a rhombic dodecahedron. In fact, the box was actually a puzzle box, and required a special, awkward three-fingered grip to open. And the two halves fit so well together that you couldn't even see the seam. The President looked the beautiful box over trying to find a way to open it without luck. She handed the box back to him saying, \"I don't know how to open it!\" Larry Joe then twirled it around, found the seam, and carefully slid the two halves open. He removed the ring and placed it on The President's finger. And finally, she tearfully said \"YES!\" and kissed him.\nThe party then moved up to the house and the champagne flowed. The President excitedly called her parents and more friends to come and join the celebration. She beamed with joy, showing off her ring to everyone. Larry Joe likewise had a grin from ear to ear: his crazy plan, a perfect reflection of his personality, had come off without a hitch and he was now engaged to his best friend.",

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers.

As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nThese newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc. [1, 8] to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.",

        "evidence": "In the past few years, there has been much interest in applying neural network based deep learning techniques to solve all kinds of natural language processing (NLP) tasks. From low level tasks such as language modeling, POS tagging, named entity recognition, and semantic role labeling BIBREF0 , BIBREF1 , to high level tasks such as machine translation, information retrieval, semantic analysis BIBREF2 , BIBREF3 , BIBREF4 and sentence relation modeling tasks such as paraphrase identification and question answering BIBREF5 , BIBREF6 , BIBREF7 . Deep representation learning has demonstrated its importance for these tasks. All the tasks get performance improvement via learning either word level representations or sentence level representations.\nIn this work, we brought deep representation learning technologies to the clinical domain. Specifically, we focus on clinical information extraction, using clinical notes and pathology reports from the Mayo Clinic. Our system will identify event expressions consisting of the following components:\nThe input of our system consists of raw clinical notes or pathology reports like below:\nAnd output annotations over the text that capture the key information such as event mentions and attributes. Table TABREF7 illustrates the output of clinical information extraction in details.\nTo solve this task, the major challenge is how to precisely identify the spans (character offsets) of the event expressions from raw clinical notes. Traditional machine learning approaches usually build a supervised classifier with features generated by the Apache clinical Text Analysis and Knowledge Extraction System (cTAKES) . For example, BluLab system BIBREF8 extracted morphological(lemma), lexical(token), and syntactic(part-of-speech) features encoded from cTAKES. Although using the domain specific information extraction tools can improve the performance, learning how to use it well for clinical domain feature engineering is still very time-consuming. In short, a simple and effective method that only leverage basic NLP modules and achieves high extraction performance is desired to save costs.\nTo address this challenge, we propose a deep neural networks based method, especially convolution neural network BIBREF0 , to learn hidden feature representations directly from raw clinical notes. More specifically, one method first extract a window of surrounding words for the candidate word. Then, we attach each word with their part-of-speech tag and shape information as extra features. Then our system deploys a temporal convolution neural network to learn hidden feature representations. Finally, our system uses Multilayer Perceptron (MLP) to predict event spans. Note that we use the same model to predict event attributes.\nTo address this challenge, we propose a deep neural networks based method, especially convolution neural network, to learn hidden feature representations directly from raw clinical notes.",

        "answer": "The error rate is a useful way to evaluate model quality: the lower the model error rate—assuming constant annotator quality and context-difficulty—the better the model.",
        "evidence": "The dataset statistics can be found in Table TABREF7. The number of examples we collected increases per round, starting with approximately 19k examples for Round 1, to around 47k examples for Round 2, to over 103k examples for Round 3. We collected more data for later rounds not only because that data is likely to be more interesting, but also simply because the base model is better and so annotation took longer to collect good, verified correct examples of model vulnerabilities.\nFor each round, we report the model error rate, both on verified and unverified examples. The unverified model error rate captures the percentage of examples where the model disagreed with the writer's target label, but where we are not (yet) sure if the example is correct. The verified model error rate is the percentage of model errors from example pairs that other annotators were able to confirm the correct label for. Note that this error rate represents a straightforward way to evaluate model quality: the lower the model error rate—assuming constant annotator quality and context-difficulty—the better the model.\nWe observe that model error rates decrease as we progress through rounds. In Round 3, where we included a more diverse range of contexts from various domains, the overall error rate went slightly up compared to the preceding round, but for Wikipedia contexts the error rate decreased substantially. While for the first round roughly 1 in every 5 examples were verified model errors, this quickly dropped over consecutive rounds, and the overall model error rate is less than 1 in 10. On the one hand, this is impressive, and shows how far we have come with just three rounds. On the other hand, it shows that we still have a long way to go if even untrained annotators can fool ensembles of state-of-the-art models with relative ease.\nTable TABREF7 also reports the average number of “tries”, i.e., attempts made for each context until a model error was found (or the number of possible tries is exceeded), and the average time this took (in seconds). Again, these metrics represent a useful way to evaluate model quality. We observe that the average tries and average time per verified error both go up as we progress through the rounds. The numbers clearly demonstrate that the rounds are getting increasingly more difficult.\nNote that error rate is a useful way to evaluate model quality: the lower the model error rate—assuming constant annotator quality and context-difficulty—the better the model.",

        "evidence": "We utilize an off-the-shelf toolbox of OpenIE to the derive structured answer-relevant relations from sentences as to the point contexts. Relations extracted by OpenIE can be represented either in a triple format or in an n-ary format with several secondary arguments, and we employ the latter to keep the extractions as informative as possible and avoid extracting too many similar relations in different granularities from one sentence. We join all arguments in the extracted n-ary relation into a sequence as our to the point context. Figure FIGREF5 shows n-ary relations extracted from OpenIE. As we can see, OpenIE extracts multiple relations for complex sentences. Here we select the most informative relation according to three criteria in the order of descending importance: (1) having the maximal number of overlapped tokens between the answer and the relation; (2) being assigned the highest confidence score by OpenIE; (3) containing maximum non-stop words. As shown in Figure FIGREF5, our criteria can select answer-relevant relations (waved in Figure FIGREF5), which is especially useful for sentences with extraneous information. In rare cases, OpenIE cannot extract any relation, we treat the sentence itself as the to the point context.\nTable TABREF8 shows some statistics to verify the intuition that the extracted relations can serve as more to the point context. We find that the tokens in relations are 61% more likely to be used in the target question than the tokens in sentences, and thus they are more to the point. On the other hand, on average the sentences contain one more question token than the relations (1.86 v.s. 2.87). Therefore, it is still necessary to take the original sentence into account to generate a more accurate question.\nRelations extracted by OpenIE can be represented either in a triple format or in an n-ary format with several secondary arguments, and we employ the latter to keep the extractions as informative as possible and avoid extracting too many similar relations in different granularities from one sentence.",

Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed U.S. colonial settlement in the Northwest Territory.",
        "answer": "The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by Congress on 17 February 1815.\n\nTensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed U.S. colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the U.S. was split on how to respond, and although majorities in both the House and Senate voted for war, they divided along strict party lines, with the Democratic-Republican Party in favour and the Federalist Party against. News of British concessions made in an attempt to avoid war did not reach the U.S. until late July, by which time the conflict was already underway.\nAt sea, the far larger Royal Navy imposed an effective blockade on U.S. maritime trade, while between 1812 to 1814 British regulars and colonial militia defeated a series of American attacks on Upper Canada. This was balanced by the US winning control of the Northwest Territory with victories at Lake Erie and the Thames in 1813. The abdication of Napoleon in early 1814 allowed the British to send additional troops to North America and the Royal Navy to reinforce their blockade, crippling the American economy. In August 1814, negotiations began in Ghent, with both sides wanting peace; the British economy had been severely impacted by the trade embargo, while the Federalists convened the Hartford Convention in December to formalise their opposition to the war.\n\nIn August 1814, British troops burned Washington, before American victories at Baltimore and Plattsburgh in September ended fighting in the north. Fighting continued in the Southeastern United States, where in late 1813 a civil war had broken out between a Creek faction supported by Spanish and British traders and those backed by the U.S. Supported by U.S. militia under General Andrew Jackson, the U.S.-backed Creeks won a series of victories, culminating in the capture of Pensacola in November 1814. In early 1815, Jackson defeated a British attack on New Orleans, catapulting him to national celebrity and later victory in the 1828 United States presidential election. News of this success arrived in Washington at the same time as that of the signing of the Treaty of Ghent, which essentially restored the position to that prevailing before the war. While Britain insisted this included lands belonging to their Native American allies prior to 1811, as Congress did not recognize them as independent nations, the Americans did not comply with these provisions and the British made no effort to compel them to do so. The Native Americans were subsequently pushed west of the Mississippi River.",

        "evidence": "Our framework combines text-embedding, geometric graph construction and multi-resolution community detection to identify, rather than impose, content-based clusters from free, unstructured text in an unsupervised manner.\nFigure 1 shows a summary of our pipeline. First, we pre-process each document to transform text into consecutive word tokens, where words are in their most normalised forms, and some words are removed if they have no distinctive meaning when used out of context BIBREF5 , BIBREF6 . We then train a paragraph vector model using the Document to Vector (Doc2Vec) framework BIBREF7 on the whole set (13 million) of preprocessed text records, although training on smaller sets (1 million) also produces good results. This training step is only done once. This Doc2Vec model is subsequently used to infer high-dimensional vector descriptions for the text of each of the 3229 documents in our target analysis set. We then compute a matrix containing pairwise similarities between any pair of document vectors, as inferred with Doc2Vec. This matrix can be thought of as a full, weighted graph with documents as nodes and edges weighted by their similarity. We sparsify this graph to the union of a minimum spanning tree and a k-Nearest Neighbors (MST-kNN) graph BIBREF8 , a geometric construction that removes less important similarities but preserves global connectivity for the graph and, hence, for the dataset. The derived MST-kNN graph is analysed with Markov Stability BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , a multi-resolution dynamics-based graph partitioning method that identifies relevant subgraphs (i.e., clusters of documents) at different levels of granularity. MS uses a diffusive process on the graph to reveal the multiscale organisation at different resolutions without the need for choosing a priori the number of clusters, scale or organisation. To analyse a posteriori the different partitions across levels of resolution, we use both visualisations and quantitative scores. The visualisations include word clouds to summarise the main content, graph layouts, as well as Sankey diagrams and contingency tables that capture the correspondences across levels of resolution and relationships to the hand-coded classifications. The partitions are also evaluated quantitatively to score: (i) their intrinsic topic coherence (using pairwise mutual information BIBREF13 , BIBREF14 ), and (ii) their similarity to the operator hand-coded categories (using normalised mutual information BIBREF15 ). We now expand on the steps of the computational framework.\nOur framework combines text-embedding, geometric graph construction and multi-resolution community detection to identify, rather than impose, content-based clusters from free, unstructured text in an unsupervised manner.",

        "answer": "It contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words.",
        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nWe experiment with the WikiBio dataset (Lebret et al., 2016) which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words.",

We manually investigate the errors made by artificial neural networks for morphological inflection in a target language after pretraining on different source languages. We aim at finding answers to two main questions: (i) Do errors systematically differ between source languages? (ii) Do these differences seem explainable, given the properties of the source and target languages? In other words, we are interested in exploring if and how L2 acquisition of morphological inflection depends on the L1, i.e., the \"native language\", in neural network models.\nFor our qualitative analysis, we make use of the validation set.

Be sure to plan your trip and purchase tickets in advance to ensure that you save money. Also, while Munich has one major airport (MUC), Rome has two large international airports (FCO and CIA). It will take roughly 90 minutes by plane to travel from Munich to Rome, not accounting for time in the airport, security lines and customs.\n\n2. By train - Traveling by train is another common way to get from Munich to Rome. While it will take longer than by air, tickets are very inexpensive and can be purchased the day of travel. A one way train ticket from Munich to Rome will cost roughly $35 (32 Euros), and take between 9-12 hours, depending on the route and number of stops.\n\n3. By car - Traveling by car from Munich to Rome is also an option. With limited stops, it will take roughly 10 hours to drive from Munich to Rome, but having a car will allow you flexibility to stop along the way at any cities or sites that you want to see. \n\nDepending on your specific needs, all three of these options could be viable ways to travel from Munich to Rome.",

        "evidence": "In Yugoslavia, organized effort in machine translation started in 1959, but the first individual effort was made by Vladimir Matković from the Institute for Telecommunications in Zagreb in 1957 in his PhD thesis on entropy in the Croatian language BIBREF10. The main research group in machine translation was formed in 1958, at the Circle for Young Linguists in Zagreb, initiated by a young linguist Bulcsu Laszlo, who graduated in Russian language, Southern Slavic languages and English language and literature at the University of Zagreb in 1952. The majority of the group members came from different departments of the Faculty of Humanities and Social Sciences of the University of Zagreb, with several individuals from other institutions. The members from the Faculty of Humanities and Social Sciences were: Svetozar Petrović (Department of Comparative Literature), Stjepan Babić (Department of Serbo-Croatian Language and Literature), Krunoslav Pranjić (Department of Serbo-Croatian Language and Literature), Željko Bujas (Department of English Language and Literature), Malik Mulić (Department of Russian Language and Literature) and Bulcsu Laszlo (Department of Comparative Slavistics). The members of the research group from outside the Faculty of Humanities and Social Sciences were: Božidar Finka (Institute for Language of the Yugoslav Academy of Sciences and Arts), Vladimir Vranić (Center for Numerical Research of the Yugoslav Academy of Sciences and Arts), Vladimir Matković (Institute for Telecommunications), Vladimir Muljević (Institute for Regulatory and Signal Devices) BIBREF10.\nLaszlo and Petrović BIBREF11 also commented on the state of the art of the time, noting the USA prototype efforts from 1954 and the publication of a collection of research papers in 1955 as well as the USSR efforts starting from 1955 and the UK prototype from 1956. They do not detail or cite the articles they mention. However, the fact that they referred to them in a text published in 1959 (probably prepared for publishing in 1958, based on BIBREF11, where Laszlo and Petrović described that the group had started its work in 1958) leads us to the conclusion that the poorly funded Croatian research was lagging only a couple of years behind the research of the superpowers (which invested heavily in this effort). Another interesting moment, which they delineated in BIBREF11, is that the group soon discovered that some experimental work had already been done in 1957 at the Institute of Telecommunications (today a part of the Faculty of Electrical Engineering and Computing at the University of Zagreb) by Vladimir Matković. Because of this, they decided to include him in the research group of the Faculty of Humanities and Social Sciences at the University of Zagreb. The work done by Matković was documented in his doctoral dissertation but remained unpublished until 1959.\nThe Russian machine translation pioneer Andreev expressed hope that the Yugoslav (Croatian) research group could create a prototype, but sadly, due to the lack of federal funding, this never happened BIBREF10. Unlike their colleagues in the USA and the USSR, Laszlo’s group had to manage without an actual computer (which is painfully obvious in BIBREF12), and the results remained mainly theoretical. Appealing probably to the political circles of the time, Laszlo and Petrović note that, although it sounds strange, research in computational linguistics is mainly a top-priority military effort in other countries BIBREF11. There is a quote from BIBREF10 which perhaps best delineates the optimism and energy that the researchers in Zagreb had:\n\"[...] The process of translation has to mechanicalized as soon as possible, and this is only possible if a competent, fast and inexhaustible machine which could inherit the translation task is created, even if just schematic. The machine needs to think for us. If machines help humans in physical tasks, why would they not help them in mental tasks with their mechanical memory and automated logic\" (p. 118).\nFinka and Laszlo envisioned three main data preparation tasks that are needed before prototype development could commence [7]. The first task is to compile a dictionary of words sorted from the end of the word to the beginning. This would enable the development of what is now called stemming and lemmatization modules: a knowledge base with suffixes so they can be trimmed, but also a systematic way to find the base of the word (lemmatization) (p. 121). The second task would be to make a word frequency table. This would enable focusing on a few thousand most frequent words and dropping the rest. This is currently a good industrial practice for building efficient natural language processing systems, and in 1962, it was a computational necessity. The last task was to create a good thesaurus, but such a thesaurus where every data point has a ”meaning” as the key, and words (synonyms) as values. The prototype would then operate on these meanings when they become substituted for words.",

        "evidence": "Subword segmentation has become a standard preprocessing step in many neural approaches to natural language processing (NLP) tasks, e.g Neural Machine Translation (NMT) BIBREF0 and Automatic Speech Recognition (ASR) BIBREF1. Word level modeling suffers from sparse statistics, issues with Out-of-Vocabulary (OOV) words, and heavy computational cost due to a large vocabulary. Word level modeling is particularly unsuitable for morphologically rich languages, but subwords are commonly used for other languages as well. Subword segmentation is best suited for languages with agglutinative morphology.\nWhile rule-based morphological segmentation systems can achieve high quality, the large amount of human effort needed makes the approach problematic, particularly for low-resource languages. The systems are language dependent, necessitating use of multiple tools in multilingual setups. As a fast, cheap and effective alternative, data-driven segmentation can be learned in a completely unsupervised manner from raw corpora. Unsupervised morphological segmentation saw much research interest until the early 2010's; for a survey on the methods, see hammarstrom2011unsupervised. Semi-supervised segmentation with already small amounts of annotated training data was found to improve the accuracy significantly when compared to a linguistic segmentation; see ruokolainen2016comparative for a survey. While this line of research has been continued in supervised and more grammatically oriented tasks BIBREF2, the more recent work on unsupervised segmentation is less focused on approximating a linguistically motivated segmentation. Instead, the aim has been to tune subword segmentations for particular applications. For example, the simple substitution dictionary based Byte Pair Encoding segmentation algorithm BIBREF3, first proposed for NMT by sennrich2015neural, has become a standard in the field. Especially in the case of multilingual models, training a single language-independent subword segmentation method is preferable to linguistic segmentation BIBREF4.\nIn this study, we compare three existing and one novel subword segmentation method, all sharing the use of a unigram language model in a generative modeling framework.

The act followed the Angell Treaty of 1880, a set of revisions to the U.S.–China Burlingame Treaty of 1868 that allowed the U.S. to suspend Chinese immigration. The act was initially intended to last for 10 years, but was renewed and strengthened in 1892 with the Geary Act and made permanent in 1902. These laws attempted to stop all Chinese immigration into the United States for ten years, with exceptions for diplomats, teachers, students, merchants, and travelers. They were widely evaded.\n\nThe law remained in force until the passage of the Magnuson Act in 1943, which repealed the exclusion and allowed 105 Chinese immigrants to enter the United States each year. Chinese immigration later increased with the passage of the Immigration and Nationality Act of 1952, which abolished direct racial barriers, and later by the Immigration and Nationality Act of 1965, which abolished the National Origins Formula.",

Modern NER has been dominated by neural models BIBREF0, BIBREF1 combined with contextual embeddings from language models (LMs) BIBREF2, BIBREF3, BIBREF4. The LMs are pre-trained on large amounts of unlabeled text which allows the NER model to use the syntactic and semantic information captured by the LM embeddings.

His freshman album topped the Billboard charts for a long stretch of time and featured absolutely iconic and inspired tracks such as \"Jesus Walks\", \"Family Business\", and of course \"Through The Wire\", the infamous track where Kanye provided vocals following a car crash that forced his jaw to be wired shut as a result.\n\nFollowing his initial success, Kanye released banger after banger with \"Late Registration\" and his stadium album \"Graduation\". He followed on to release what many consider to be his magnum opus with \"My Beautiful Dark Twisted Fantasy\" which received critical acclaim despite mixed reviews from popular internet music nerd Anthony Fantano.\n\nNot to be stopped, Kanye was on the track to certified Godhood, dropping \"808s and Heartbreak\", a track that laid the foundation for artists like Juice WRLD, Frank Ocean, and The Weekend to discover their own sounds.

The goal of question generation (QG) is to generate a question that asks towards the answer with the given passage and the expected answer. In the following experiments, we extend the QG task to the cross-lingual setting. By only using English QG training data, our goal is to generate questions in English or Chinese with the given passage-answer pair in English or Chinese.\nWe use SQuAD 1.1 BIBREF30 as the English QG dataset. It is a popular English question answering dataset containing over 100,000 questions and their corresponding annotated passages. Following BIBREF31, we regard the original development set as the test set, and sample 5000 examples from the training data of two datasets as the development sets. For Chinese QG, we follow the default data splits of WebQA BIBREF32. We regard the provided annotated evidence sentences as the input passages instead of entire documents. To construct the input sequence, we view the whole input passage as a single sentence, and concatenate the passage and the answer into one sequence with a special token S between them. During decoding Chinese, we utilize a subset of vocabulary, which is obtained from the passage sentences of the WebQA dataset.\nWe first conduct experiments on the supervised English-English QG setting. We compare our model to the following baselines:\nCorefNqg BIBREF33 A sequence-to-sequence model with attention mechanism and a feature-rich encoder.\nMp-Gsn BIBREF31 A sequence-to-sequence model with gated self-attention and maxout pointer mechanism.\nXlm BIBREF5 The current state-of-the-art cross-lingual pre-training model. We initialize the Transformer-based sequence-to-sequence model with pre-trained XLM.\nWe evaluate models with BLEU-4 (BL-4), ROUGE (RG) and METEOR (MTR) metrics. As shown in Table TABREF16, our model outperforms the baselines, which demonstrates that our pre-trained model provides a good initialization for NLG.\nWe conduct experiments on the zero-shot Chinese-Chinese QG task to evaluate the cross-lingual transfer ability. In this task, models are trained with English QG data but evaluated with Chinese QG examples. We include the following models as our baselines:\nXlm Fine-tuning XLM with the English QG data.\nPipeline (Xlm) The pipeline of translating input Chinese sentences into English first, then performing En-En-QG with the XLM model, and finally translating back to the Chinese. We use the Transformer as the translator, which is also trained on the MultiUN dataset.\nPipeline (Xlm) with Google Translator Same to Pipeline (Xlm) but using Google Translator to translate the texts.\nWe evaluate models by both automatic evaluation metrics and human experts. The automatic metrics scores are computed by regarding each Chinese character as a token. For human evaluation, we consider three metrics for the generated questions: relatedness, fluency, and correctness, which are represented as integers ranged from 1 to 3. We randomly select 100 passage-answer pairs from the English QG test set, and use the models to generate questions. Then we present these examples to three experts to ask for the above scores. In Table TABREF17 and Table TABREF18, we present the results for the zero-shot Zh-Zh-QG. The results of monolingual supervised models are also reported in Table TABREF16 as reference. In the automatic evaluation, our model consistently performs better than baselines in both zero-shot and monolingual supervised setting. In the human evaluation, our model also obtains significant improvements in terms of relatedness and correctness.\nIn the zero-shot English-Chinese question generation experiments, we use Xlm and Pipeline (Xlm) as our baselines. Pipeline (Xlm) is a pipeline method that uses En-En-QG with Xlm to generate questions, and then translates the results to Chinese. Because there is no annotations for En-Zh-QG, we perform human evaluation studies for this setting. Table TABREF19 shows the human evaluation results, where our model surpasses all the baselines especially in terms of relatedness and correctness.\nWe also conduct experiments for zero-shot Chinese-English question generation, and adopt the same evaluation procedure to En-Zh-QG. Pipeline (Xlm) first translates Chinese input to English, and then conduct En-En-QG with Xlm.

A spokesman for the Nation of Islam until 1964, he was a vocal advocate for Black empowerment and the promotion of Islam within the Black community. A posthumous autobiography, on which he collaborated with Alex Haley, was published in 1965.\n\nMalcolm spent his adolescence living in a series of foster homes or with relatives after his father's death and his mother's hospitalization. He committed various crimes, being sentenced to 10 years in prison in 1946 for larceny and burglary. In prison he joined the Nation of Islam (adopting the name Malcolm X to symbolize his unknown African ancestral surname while discarding \"the White slavemaster name of 'Little'\"), and after his parole in 1952 quickly became one of the organization's most influential leaders. He was the public face of the organization for 12 years, advocating Black empowerment and separation of Black and White Americans, and criticizing Martin Luther King Jr. and the mainstream civil rights movement for its emphasis on nonviolence and racial integration. Malcolm X also expressed pride in some of the Nation's social welfare achievements, such as its free drug rehabilitation program. From the 1950s onward, Malcolm X was subjected to surveillance by the Federal Bureau of Investigation (FBI).\n\nIn the 1960s, Malcolm X began to grow disillusioned with the Nation of Islam, as well as with its leader, Elijah Muhammad. He subsequently embraced Sunni Islam and the civil rights movement after completing the Hajj to Mecca, and became known as \"el-Hajj Malik el-Shabazz,\" which roughly translates to \"The Pilgrim Malcolm the Patriarch\". After a brief period of travel across Africa, he publicly renounced the Nation of Islam and founded the Islamic Muslim Mosque, Inc. (MMI) and the Pan-African Organization of Afro-American Unity (OAAU). Throughout 1964, his conflict with the Nation of Islam intensified, and he was repeatedly sent death threats. On February 21, 1965, he was assassinated in New York City. Three Nation members were charged with the murder and given indeterminate life sentences; in 2021, two of the convictions were vacated. Speculation about the assassination and whether it was conceived or aided by leading or additional members of the Nation, or with law enforcement agencies, has persisted for decades.\n\nA controversial figure accused of preaching racism and violence, Malcolm X is also a widely celebrated figure within African-American and Muslim American communities for his pursuit of racial justice. He was posthumously honored with Malcolm X Day, on which he is commemorated in various cities across the United States. Hundreds of streets and schools in the U.S. have been renamed in his honor, while the Audubon Ballroom, the site of his assassination, was partly redeveloped in 2005 to accommodate the Malcolm X and Dr. Betty Shabazz Memorial and Educational Center.",

        "question": "Was the proposed approach better than the BM25 ranking?",
        "answer": "Yes, it is.",
        "evidence": "In information retrieval (IR), queries and documents are typically represented by term vectors where each term is a content word and weighted by tf-idf, i.e. the product of the term frequency and the inverse document frequency, or other weighting schemes BIBREF0 . The similarity of a query and a document is then determined as a dot product or cosine similarity. Although this works reasonably, the traditional IR scheme often fails to find relevant documents when synonymous or polysemous words are used in a dataset, e.g. a document including only “neoplasm\" cannot be found when the word “cancer\" is used in a query. One solution of this problem is to use query expansion BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 or dictionaries, but these alternatives still depend on the same philosophy, i.e. queries and documents should share exactly the same words.\nWhile the term vector model computes similarities in a sparse and high-dimensional space, the semantic analysis methods such as latent semantic analysis (LSA) BIBREF5 , BIBREF6 and latent Dirichlet allocation (LDA) BIBREF7 learn dense vector representations in a low-dimensional space. These methods choose a vector embedding for each term and estimate a similarity between terms by taking an inner product of their corresponding embeddings BIBREF8 . Since the similarity is calculated in a latent (semantic) space based on context, the semantic analysis approaches do not require having common words between a query and documents. However, it has been shown that LSA and LDA methods do not produce superior results in various IR tasks BIBREF9 , BIBREF10 , BIBREF11 and the classic ranking method, BM25 BIBREF12 , usually outperforms those methods in document ranking BIBREF13 , BIBREF14 .\nNeural word embedding BIBREF15 , BIBREF16 is similar to the semantic analysis methods described above. It learns low-dimensional word vectors from text, but while LSA and LDA utilize co-occurrences of words, neural word embedding learns word vectors to predict context words BIBREF10 . Moreover, training of semantic vectors is derived from neural networks. Both co-occurrence and neural word embedding approaches have been used for lexical semantic tasks such as semantic relatedness (e.g. king and queen), synonym detection (e.g. cancer and carcinoma) and concept categorization (e.g. banana and pineapple belong to fruits) BIBREF10 , BIBREF17 . But, Baroni et al. Baroni2014 showed that neural word embedding approaches generally performed better on such tasks with less effort required for parameter optimization. The neural word embedding models have also gained popularity in recent years due to their high performance in NLP tasks BIBREF18 .\nHere we present a query-document similarity measure using a neural word embedding approach. This work is particularly motivated by the Word Mover's Distance BIBREF19 . Unlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document. Our first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets BIBREF20 , BIBREF21 , and the experimental results showed that our approach was better than BM25 ranking. This was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.\nIn general, conventional ranking models (e.g. BM25) rely on a manually designed ranking function and require heuristic optimization for parameters BIBREF22 , BIBREF23 . In the age of information explosion, this one-size-fits-all solution is no longer adequate. For instance, it is well known that links to a web page are an important source of information in web document search BIBREF24 , hence using the link information as well as the relevance between a query and a document is crucial for better ranking. In this regard, learning to rank BIBREF22 has drawn much attention as a scheme to learn how to combine diverse features. Given feature vectors of documents and their relevance levels, a learning to rank approach learns an optimal way of weighting and combining multiple features.\nWe argue that the single scores (or features) produced by BM25 and our proposed semantic measure complement each other, thus merging these two has a synergistic effect. To confirm this, we measured the impact on document ranking by combining BM25 and semantic scores using the learning to rank approach, LamdaMART BIBREF25 , BIBREF26 . Trained on PubMed user queries and their click-through data, we evaluated the search performance based on the most highly ranked 20 documents. As a result, we found that using our semantic measure further improved the performance of BM25.\nTaken together, we make the following important contributions in this work. First, to the best of our knowledge, this work represents the first investigation of query-document similarity for information retrieval using the recently proposed Word Mover's Distance. Second, we modify the original Word Mover's Distance algorithm so that it is computationally less expensive and thus more practical and scalable for real-world search scenarios (e.g. biomedical literature search). Third, we measure the actual impact of neural word embeddings in PubMed by utilizing user queries and relevance information derived from click-through data. Finally, on TREC and PubMed datasets, our proposed method achieves stronger performance than BM25.\nOur first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets, and the experimental results showed that our approach was better than BM25 ranking.",

Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today’s status quo approach [1].",

        "evidence": "AMR is not grounded in the input sentence, therefore there is no need to change the AMR annotation when projecting to another language. We think of English labels for the graph nodes as ones from an independent language, which incidentally looks similar to English.

We use word alignments, similarly to other annotation projection work, to project the AMR alignments to the target languages.\nOur approach depends on an underlying assumption that we make: if a source word is word-aligned to a target word and it is AMR aligned with an AMR node, then the target word is also aligned to that AMR node. More formally, let $S = s_1 \\dots s_{\\vert s \\vert }$ be the source language sentence and $T = t_1 \\dots t_{\\vert t \\vert }$ be the target language sentence; $A_s(\\cdot )$ be the AMR alignment mapping word tokens in $S$ to the set of AMR nodes that are triggered by it; $A_t(\\cdot )$ be the same function for $T$ ; $v$ be a node in the AMR graph; and finally, $W(\\cdot )$ be an alignment that maps a word in $S$ to a subset of words in $T$ .

        "question": "Given these paragraphs about Large language models, what corpus was the first model in OpenAI's GPT series trained in 2018 on?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

Given that pB is usually 0, the equation becomes R=-C +D and in order for the R to be a positive value (which means a citizen will vote), we need civic duty to “outweigh” the cost of voting. \nThe Rational Choice model has two competing views on how voters choose to vote.  One is proximity voting.  In this case, the voter chooses the candidate that they are the closest to in terms of where that candidate sits on a liberal/conservative line.  The other view is directional voting, which says the voter will vote for whomever is on their “side” of the scale.

He attended King Edward VI Grammar School in Chelmsford and Felsted School, before completed National Service in Germany. In 1951, he began undergraduate studies at St John's College, Cambridge under Patrick Hadley and Robin Orr. On graduating in 1954, he began working for Schott & Co., the music publisher. In 1959, he was appointed an assistant lecturer at the University of Aberdeen; he briefly returned to Schott's (1962–64) as head of promotion, but then went back to Aberdeen, this time to take up a senior lectureship. He was elected a fellow of St John's College, Cambridge, in 1971, remaining there until his appointment to the West Riding Chair of Music at the University of Leeds in 1977. He moved to the University of Manchester in 1981 to be Professor of Music, and remained there until retirement in 1991.\n\nKemp's time at Schott's brought him into contact with distinguished composers, including Michael Tippett, Alexander Goehr, Peter Maxwell Davies and Harrison Birtwistle. He became an expert on Tippett's music, and at Aberdeen he edited Michael Tippett: A Symposium on his 60th Birthday in 1965. His time at Manchester, which The Guardian considers the \"culmination\" of his career, saw him write a biography of Tippett in 1984, which The Times considered \"masterly\". He was also a specialist in Paul Hindemith, surveying his work in 1970, and Hector Berlioz, editing the Cambridge Opera Handbook on Berlioz's Les Troyens in 1989.\n\nIn his retirement, he lived in North London and then Sussex, but health problems slowed down his scholarly output. He died on 16 September 2011, leaving a widow, the conductor Sian Edwards, and their son, and five children from his first marriage to Gill Turner.",

        "answer": "2.2 million.",
        "evidence": "Given the large collections of unstructured and semi-structured data available on the web, there is a crucial need to enable quick and efficient access to the knowledge content within them. Traditionally, the field of information extraction has focused on extracting such knowledge from unstructured text documents, such as job postings, scientific papers, news articles, and emails. However, the content on the web increasingly contains more varied types of data, including semi-structured web pages, tables that do not adhere to any schema, photographs, videos, and audio. Given a query by a user, the appropriate information may appear in any of these different modes, and thus there's a crucial need for methods to construct knowledge bases from different types of data, and more importantly, combine the evidence in order to extract the correct answer.\nMotivated by this goal, we introduce the task of multimodal attribute extraction. Provided contextual information about an entity, in the form of any of the modes described above, along with an attribute query, the goal is to extract the corresponding value for that attribute. While attribute extraction on the domain of text has been well-studied BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , to our knowledge this is the first time attribute extraction using a combination of multiple modes of data has been considered. This introduces additional challenges to the problem, since a multimodal attribute extractor needs to be able to return values provided any kind of evidence, whereas modern attribute extractors treat attribute extraction as a tagging problem and thus only work when attributes occur as a substring of text.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API. The collection of items is diverse and includes categories such as electronic products, jewelry, clothing, vehicles, and real estate. For each item, we provide a textual product description, collection of images, and open-schema table of attribute-value pairs (see Figure 1 for an example). The provided attribute-value pairs only provide a very weak source of supervision; where the value might appear in the context is not known, and further, it is not even guaranteed that the value can be extracted from the provided evidence. In all, there are over 4 million images and 7.6 million attribute-value pairs. By releasing such a large dataset, we hope to drive progress on this task similar to how the Penn Treebank BIBREF5 , SQuAD BIBREF6 , and Imagenet BIBREF7 have driven progress on syntactic parsing, question answering, and object recognition, respectively.\nTo asses the difficulty of the task and the dataset, we first conduct a human evaluation study using Mechanical Turk that demonstrates that all available modes of information are useful for detecting values. We also train and provide results for a variety of machine learning models on the dataset. We observe that a simple most-common value classifier, which always predicts the most-common value for a given attribute, provides a very difficult baseline for more complicated models to beat (33% accuracy). In our current experiments, we are unable to train an image-only classifier that can outperform this simple model, despite using modern neural architectures such as VGG-16 BIBREF8 and Google's Inception-v3 BIBREF9 . However, we are able to obtain significantly better performance using a text-only classifier (59% accuracy). We hope to improve and obtain more accurate models in further research.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API.",

        "evidence": "Writing errors can occur in many different forms – from relatively simple punctuation and determiner errors, to mistakes including word tense and form, incorrect collocations and erroneous idioms. Automatically identifying all of these errors is a challenging task, especially as the amount of available annotated data is very limited. Rei2016 showed that while some error detection algorithms perform better than others, it is additional training data that has the biggest impact on improving performance.\nBeing able to generate realistic artificial data would allow for any grammatically correct text to be transformed into annotated examples containing writing errors, producing large amounts of additional training examples. Supervised error generation systems would also provide an efficient method for anonymising the source corpus – error statistics from a private corpus can be aggregated and applied to a different target text, obscuring sensitive information in the original examination scripts. However, the task of creating incorrect data is somewhat more difficult than might initially appear – naive methods for error generation can create data that does not resemble natural errors, thereby making downstream systems learn misleading or uninformative patterns.\nPrevious work on artificial error generation (AEG) has focused on specific error types, such as prepositions and determiners BIBREF0 , BIBREF1 , or noun number errors BIBREF2 . Felice2014a investigated the use of linguistic information when generating artificial data for error correction, but also restricting the approach to only five error types. There has been very limited research on generating artificial data for all types, which is important for general-purpose error detection systems. For example, the error types investigated by Felice2014a cover only 35.74% of all errors present in the CoNLL 2014 training dataset, providing no additional information for the majority of errors.\nIn this paper, we investigate two supervised approaches for generating all types of artificial errors. We propose a framework for generating errors based on statistical machine translation (SMT), training a model to translate from correct into incorrect sentences. In addition, we describe a method for learning error patterns from an annotated corpus and transplanting them into error-free text. We evaluate the effect of introducing artificial data on two error detection benchmarks. Our results show that each method provides significant improvements over using only the available training set, and a combination of both gives an absolute improvement of 4.3% in INLINEFORM0 , without requiring any additional annotated data.\n \nWe propose a framework for generating errors based on statistical machine translation (SMT), training a model to translate from correct into incorrect sentences.",

        "question": "How many percent incorrect assignments does the `translated semantic fingerprints' method show in representing documents in different languages?",
        "answer": "Only 5%.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nThe authors show that the translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments.",

        "question": "What factors influence the performance of adversarial attacks?",
        "answer": "A number of factors can influence the performance of adversarial attacks, including architecture of the classifier, sentence length and input domain.",
        "evidence": "Adversarial examples, a term introduced in BIBREF0, are inputs transformed by small perturbations that machine learning models consistently misclassify. The experiments are conducted in the context of computer vision (CV), and the core idea is encapsulated by an illustrative example: after imperceptible noises are added to a panda image, an image classifier predicts, with high confidence, that it is a gibbon. Interestingly, these adversarial examples can also be used to improve the classifier — either as additional training data BIBREF0 or as a regularisation objective BIBREF1 — thus providing motivation for generating effective adversarial examples.\nThe germ of this paper comes from our investigation of adversarial attack methods for natural language processing (NLP) tasks, e.g. sentiment classification, which drives us to quantify what is an “effective” or “good” adversarial example. In the context of images, a good adversarial example is typically defined according two criteria:\nit has successfully fooled the classifier;\nit is visually similar to the original example.\nIn NLP, defining a good adversarial example is a little more involving, because while criterion (b) can be measured with a comparable text similarity metric (e.g. BLEU or edit distance), an adversarial example should also:\nbe fluent or natural;\npreserve its original label.\nThese two additional criteria are generally irrelevant for images, as adding minor perturbations to an image is unlikely to: (1) create an uninterpretable image (where else changing one word in a sentence can render a sentence incoherent), or (2) change how we perceive the image, say from seeing a panda to a gibbon (but a sentence's sentiment can be reversed by simply adding a negative adverb such as not). Without considering criterion (d), generating adversarial examples in NLP would be trivial, as the model can learn to simply replace a positive adjective (amazing) with a negative one (awful) to attack a sentiment classifier.\nTo the best of our knowledge, most studies on adversarial example generation in NLP have largely ignored these additional criteria BIBREF2, BIBREF3, BIBREF4, BIBREF5. We believe the lack of a rigorous evaluation framework partially explains why adversarial training for NLP models has not seen the same extent of improvement compared to CV models. As our experiments reveal, examples generated from most attacking methods are successful in fooling the classifier, but their language is often unnatural and the original label is not properly preserved.\nThe core contribution of our paper is to introduce a systematic, rigorous evaluation framework to assess the quality of adversarial examples for NLP. We focus on sentiment classification as the target task, as it is a popular application that highlights the importance of criteria discussed above. We test a number of attacking methods and also propose an alternative approach (based on an auto-encoder) for generating adversarial examples. We learn that a number of factors can influence the performance of adversarial attacks, including architecture of the classifier, sentence length and input domain.\nWe learn that a number of factors can influence the performance of adversarial attacks, including architecture of the classifier, sentence length and input domain.",

        "answer": "Many people are attracted to jobs that have significant travel.  The allure of traveling to new and exciting places, the potential for airline and hotel program status benefits, meeting new people, etc.  All of these things may be exactly what you are looking for.  But my advice for anyone who is considering a position with significant travel and who has not experienced that type of work-life before is to think about all the things in their life that they are involved with that make them happy.  Think hard about whether you can take them on the road with you, reproduce them wherever your business travel takes you, or do without them.  Perhaps you have a standing poker night each month with your friends.  You may not be able to attend that with any regularity.  You may love the climbing gym or cycling club at home.  Can you replace that with hotel gyms?  Do you stick to a diet that will be hard to keep when you need to eat out a lot?  Do you have a relationship at home that will suffer if you are gone a lot?  The list can go on and on and is different for each person.  But it is critical to evaluate this aspect of how your life will change when you travel a lot of the time and make sure you are happy with the accommodations and changes you will need to make.  Another important consideration is whether you will be traveling to different time zones.  Often the idea of globetrotting to different parts of the world is very exciting, but you will have to deal with jetlag while maintaining your work performance.  You will end up dealing with canceled or delayed flights, traffic, and other types of travel disruptions.  Ultimately, a job with significant travel can involve a lot of excitement and fun.  But it is not right for everyone. It is not vacation travel.  And being honest with yourself about what changes you will need to make, what hassles you will need to deal with, and what you will have to give up will help you make the right decision.

        "evidence": "We have presented a method for quantifying the similarity and relatedness between two terms that integrates pair–wise similarity scores into second–order vectors. The goal of this approach is two–fold. First, we restrict the context used by the vector measure to words that exist in the biomedical domain, and second, we apply larger weights to those word pairs that are more similar to each other. Our hypothesis was that this combination would reduce the amount of noise in the vectors and therefore increase their correlation with human judgments. We evaluated our method on datasets that have been manually annotated for relatedness and similarity and found evidence to support this hypothesis. In particular we discovered that guiding the creation of a second–order context vector by selecting term pairs from biomedical text based on their semantic similarity led to improved levels of correlation with human judgment.\nWe also explored using a threshold cutoff to include only those term pairs that obtained a sufficiently large level of similarity. We found that eliminating less similar pairs improved the overall results (to a point). In the future, we plan to explore metrics to automatically determine the threshold cutoff appropriate for a given dataset and measure. We also plan to explore additional features that can be integrated with a second–order vector measure that will reduce the noise but still provide sufficient information to quantify relatedness. We are particularly interested in approaches that learn word, phrase, and sentence embeddings from structured corpora such as literature BIBREF23 and dictionary entries BIBREF24 . Such embeddings could be integrated into a second–order vector or be used on their own.\nFinally, we compared our proposed method to other distributional approaches, focusing on those that used word embeddings. Our results showed that integrating semantic similarity measures into second–order co–occurrence vectors obtains the same or higher correlation with human judgments as do various different word embedding approaches. However, a direct comparison was not possible due to variations in the subsets of the UMNSRS evaluation dataset used. In the future, we would not only like to conduct a direct comparison but also explore integrating semantic similarity into various kinds of word embeddings by training on pair–wise values of semantic similarity as well as co–occurrence statistics.\nIn the future, we plan to explore metrics to automatically determine the threshold cutoff appropriate for a given dataset and measure.

        "evidence": "The Recognizing Textual Entailment (RTE) challenges first appeared in 2004 as a means to test textual entailment, i.e. relations between a premise text and a hypothesis text ( \"Recognizing Textual Entailment\" ):\nAn entailment example from RTE1.\nBudapest again became the focus of national political drama in the late 1980s, when Hungary led the reform movement in eastern Europe that broke the communist monopoly on political power and ushered in the possibility of multiparty politics.\nIn the late 1980s Budapest became the center of the reform movement.\nEntailment [RTE702]\nIn contrast to the FraCaS test suite, the RTE challenges use naturally occurring data as premises. The hypothesis text is then constructed based on this premise text. There is either a binary or a tripartite classification of entailment — depending on the version of RTE. The first two RTE challenges follow the former scheme and make a binary classification of entailment (entailed or not entailed). Tripartite classification (entailment, negation of the hypothesis entailment or no entailment) is added in the later datasets, retaining two way classification versions as well. Seven RTE challenges have been created altogether.\nThe main advantages of the RTE challenges is their use of examples from natural text and the inclusion of cases that require presupposed information, mostly world knowledge. Indeed, the very definition of inference assumed in a number of the examples is problematic. As BIBREF1 have pointed out, RTE platforms suffer from cases of inference that should not be categorized as such. For these cases, a vast amount of world knowledge needs to be taken into consideration (that most importantly not every linguistic agent has). In this paper, and having the RTE as our starting point challenges, we claim that RTE is insufficiently precise to perform logical reasoning or precise reasoning tasks and we take up the task of validating our working hypothesis and proposing a method for doing proper collection of precise entailment pairs in the style of RTE. Of course, the creators of RTE had in mind a more loose definition of inference where both a precise and an imprecise definition of entailment would be at play. BIBREF2 mention that “our applied notion of textual entailment is also related, of course, to classical semantic entailment in the linguistics literature... a common definition of entailment specifies that a text t entails another text h (hypothesis, in our terminology) if h is true in every circumstance (possible world) in which t is true.\" This is close to what we want to capture in this paper. But, at the same time, BIBREF2 also mention that “however, our applied definition allows for cases in which the truth of the hypothesis is highly plausible, for most practical purposes, rather than certain\". It is these cases we want to make more precise, in the sense of making the supporting hidden inferences that are at play in many of the RTE examples explicit. In a way, what we are aiming at is a methodology of constructing entailment datasets in the style of RTE, that will involve a more precise definition of entailment and will further record any missing/hidden premises are used in justifying or not an entailment pattern.\nThe main advantages of the RTE challenges is their use of examples from natural text and the inclusion of cases that require presupposed information, mostly world knowledge.",

        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nWhat is more, the recovery concept emerged from research primarily conducted in Englishspeaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples (Slade et al., 2012), limiting its the applicability to a general population.",

A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration. In contrast to genetics, which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of all of an organism's genes, their interrelations and influence on the organism. Genes may direct the production of proteins with the assistance of enzymes and messenger molecules. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genomics also involves the sequencing and analysis of genomes through uses of high throughput DNA sequencing and bioinformatics to assemble and analyze the function and structure of entire genomes. Advances in genomics have triggered a revolution in discovery-based research and systems biology to facilitate understanding of even the most complex biological systems such as the brain.\n\nThe field also includes studies of intragenomic (within the genome) phenomena such as epistasis (effect of one gene on another), pleiotropy (one gene affecting more than one trait), heterosis (hybrid vigour), and other interactions between loci and alleles within the genome.",

These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nCompared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.",

The \"center\" of the culture was the settlement of Tiryns that saw further development during the Mycenean period.\n\nMetal and Terracotta: A unique pattern-painted dark to light human figurine appears in Tiryns culture's Lerna IV while old types of animal figurines do not continue. Metal is now more popular for the creation of weapons and tools, some examples are : A dagger, a nail, a pin from Lerna and three axes from Thebes.\nPottery: The best known type of pottery consists of two classes of pattern-painted ceramics : 1) Patterned ware that is a dark on light class, mainly in the Peloponnese. The ornament is geometric and almost exclusively rectilinear. 2) Ayia Marina ware that is a light on dark class, mainly in Central Greece. The ornament is similar to patterned ware. The dark paint on both wares is moderately lustrous and appears to be descended directly from the Urfirnis paint on Early Helladic II period.\nArchitecture: At Lerna and Olympia several \"long houses\" (megara) with two or three rooms and narrow alleyways are built. A tumulus is constructed over the ruins of the Helladic II House of the Tiles and for a long period no buildings are built in the specific area.

        "answer": "Tiryns culture (2,200 - 2,000 BC) or Early Helladic III was an Early Bronze Age culture in Central Greece, Southern Greece and the Ionian islands (Part of Western Greece) that followed Eutresis and Korakou cultures, and preceded the Mycenean civilization. The \"center\" of the culture was the settlement of Tiryns that saw further development during the Mycenean period.\n\nMetal and Terracotta: A unique pattern-painted dark to light human figurine appears in Tiryns culture's Lerna IV while old types of animal figurines do not continue. Metal is now more popular for the creation of weapons and tools, some examples are : A dagger, a nail, a pin from Lerna and three axes from Thebes.\n\nPottery: The best known type of pottery consists of two classes of pattern-painted ceramics: 1) Patterned ware that is a dark on light class, mainly in the Peloponnese. The ornament is geometric and almost exclusively rectilinear. 2) Ayia Marina ware that is a light on dark class, mainly in Central Greece. The ornament is similar to patterned ware. The dark paint on both wares is moderately lustrous and appears to be descended directly from the Urfirnis paint on Early Helladic II period.\n\nArchitecture: At Lerna and Olympia several \"long houses\" (megara) with two or three rooms and narrow alleyways are built. A tumulus is constructed over the ruins of the Helladic II House of the Tiles and for a long period no buildings are built in the specific area. Many large (for their period) buildings are constructed in Lerna but they often last for only one generation.\n\nEnd: In around 2,000 BC, Early Helladic III and generally the Early Helladic periods end.

        "question": "Can you describe Gene expression?",
        "evidence": "",
        "answer": "Genes generally express their functional effect through the production of proteins, molecules responsible for most functions in the cell. Proteins are made up of one or more polypeptide chains, each composed of a sequence of amino acids. The DNA sequence of a gene is used to produce a specific amino acid sequence. This process begins with the production of an RNA molecule with a sequence matching the gene's DNA sequence, a process called transcription.\n\nThis messenger RNA molecule then serves to produce a corresponding amino acid sequence through a process called translation. Each group of three nucleotides in the sequence, called a codon, corresponds either to one of the twenty possible amino acids in a protein or an instruction to end the amino acid sequence; this correspondence is called the genetic code. The flow of information is unidirectional: information is transferred from nucleotide sequences into the amino acid sequence of proteins, but it never transfers from protein back into the sequence of DNA—a phenomenon Francis Crick called the central dogma of molecular biology.\n\nThe specific sequence of amino acids results in a unique three-dimensional structure for that protein, and the three-dimensional structures of proteins are related to their functions. Some are simple structural molecules, like the fibers formed by the protein collagen. Proteins can bind to other proteins and simple molecules, sometimes acting as enzymes by facilitating chemical reactions within the bound molecules (without changing the structure of the protein itself). Protein structure is dynamic; the protein hemoglobin bends into slightly different forms as it facilitates the capture, transport, and release of oxygen molecules within mammalian blood.",

Its peak reaches 1,493 m (4,898 ft) in height and in the year 1980 it covered an area of approximately 595 km2 (230 sq mi).\nThe icecap of the glacier covers an active volcano called Katla. The caldera of the volcano has a diameter of 10 km (6 mi) and the volcano erupts usually every 40–80 years. The last eruption took place in 1918. Scientists are actively monitoring the volcano, particularly after the eruption of nearby Eyjafjallajökull began in April 2010. Since the year 930, 16 eruptions have been documented.\nThe Eldgjá, a volcanic eruption fissure about 30 km (19 mi) long, which erupted in the year 936, is part of the same volcanic system.\nBefore the Hringvegur (the main ring road round the island) was built, people feared traversing the plains in front of the volcano because of the frequent jökulhlaups (glacial floods) and the deep rivers to be crossed, although the road is still vulnerable to major events. Especially dangerous was the glacial flood after the eruption of 1918 when the coastline was extended by 5 km (3.1 mi) by laharic flood deposits.\nMýrdalsjökull is an exceedingly wet location, with models suggesting it receives more than 10 metres of precipitation annually.",

To deal with this problem, BIBREF1 introduced a semantically conditioned generation model using Hierarchical Disentangled Self-Attention (HDSA) . This model deals with the large label space by representing dialog acts using a multi-layer hierarchical graph that merges cross-branch nodes. For example, the distinct trees for hotel-recommend-area and attraction-recommend-area can be merged at the second and third levels sharing semantic information about actions and slots but maintaining specific information about the domains separate. This information can then be used as part of an attention mechanism when generating a response.

        "answer": "They noticed that original relation names can sometimes help to match longer question contexts",
        "evidence": "Knowledge Base Question Answering (KBQA) systems answer questions by obtaining information from KB tuples BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 . For an input question, these systems typically generate a KB query, which can be executed to retrieve the answers from a KB. Figure 1 illustrates the process used to parse two sample questions in a KBQA system: (a) a single-relation question, which can be answered with a single $<$ head-entity, relation, tail-entity $>$ KB tuple BIBREF6 , BIBREF7 , BIBREF2 ; and (b) a more complex case, where some constraints need to be handled for multiple entities in the question. The KBQA system in the figure performs two key tasks: (1) entity linking, which links $n$ -grams in questions to KB entities, and (2) relation detection, which identifies the KB relation(s) a question refers to.\nThe main focus of this work is to improve the relation detection subtask and further explore how it can contribute to the KBQA system. Although general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection. First, in most general relation detection tasks, the number of target relations is limited, normally smaller than 100. In contrast, in KBQA even a small KB, like Freebase2M BIBREF2 , contains more than 6,000 relation types. Second, relation detection for KBQA often becomes a zero-shot learning task, since some test instances may have unseen relations in the training data. For example, the SimpleQuestions BIBREF2 data set has 14% of the golden test relations not observed in golden training tuples. Third, as shown in Figure 1 (b), for some KBQA tasks like WebQuestions BIBREF0 , we need to predict a chain of relations instead of a single relation. This increases the number of target relation types and the sizes of candidate relation pools, further increasing the difficulty of KB relation detection. Owing to these reasons, KB relation detection is significantly more challenging compared to general relation detection tasks.\nThis paper improves KB relation detection to cope with the problems mentioned above. First, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching. Second, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations. Third, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information. Finally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching.\nIn order to assess how the proposed improved relation detection could benefit the KBQA end task, we also propose a simple KBQA implementation composed of two-step relation detection. Given an input question and a set of candidate entities retrieved by an entity linker based on the question, our proposed relation detection model plays a key role in the KBQA process: (1) Re-ranking the entity candidates according to whether they connect to high confident relations detected from the raw question text by the relation detection model. This step is important to deal with the ambiguities normally present in entity linking results. (2) Finding the core relation (chains) for each topic entity selection from a much smaller candidate entity set after re-ranking. The above steps are followed by an optional constraint detection step, when the question cannot be answered by single relations (e.g., multiple entities in the question). Finally the highest scored query from the above steps is used to query the KB for answers.\nOur main contributions include: (i) An improved relation detection model by hierarchical matching between questions and relations with residual learning; (ii) We demonstrate that the improved relation detector enables our simple KBQA system to achieve state-of-the-art results on both single-relation and multi-relation KBQA tasks.\nSecond, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations.",

        "evidence": "Named entity recognition (NER) BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc. NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction BIBREF4 , machine translation BIBREF5 , question answering BIBREF6 and knowledge base construction BIBREF7 . Although early NER systems have been successful in producing adequate recognition accuracy, they often require significant human effort in carefully designing rules or features.\nIn recent years, deep learning methods been employed in NER systems, yielding state-of-the-art performance. However, the number of types detected are still not sufficient for certain domain-specific applications. For relation extraction, identifying fine-grained types has been shown to significantly increase the performance of the extractor BIBREF8 , BIBREF9 since this helps in filtering out candidate relation types which do not follow this type constraint. Furthermore, for question answering fine-grained Named Entity Recognition (FgNER) can provide additional information helping to match questions to its potential answers thus improving performance BIBREF10 . For example, Li and Roth BIBREF11 rank questions based on their expected answer types (i.e. will the answer be food, vehicle or disease).\nTypically, FgNER systems use over a hundred labels, arranged in a hierarchical structure. We find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process. Furthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task. Currently, FgNER systems use distant supervision BIBREF12 to automatically generate training data. Distant supervision is a technique which maps each entity in the corpus to knowledge bases such as Freebase BIBREF13 , DBpedia BIBREF14 , YAGO BIBREF15 and helps with the generation of labeled data. This method will assign the same set of labels to all mentions of a particular entity in the corpus. For example, “Barack Obama” is a person, politician, lawyer, and author. If a knowledge base has these four matching labels, the distant supervision technique will assign all of them to every mention of “Barack Obama”. Therefore, the training data will also fail to distinguish between mentions of “Barack Obama” in all subsequent utterances.\nLing et al. ling2012fine proposed the first system for FgNER, where they used 112 overlapping labels with a linear classifier perceptron for multi-label classification. Yosef et al. spaniol2012hyena used multiple binary SVM classifiers to assign entities to a set of 505 types. Gillick et al. gillick2014context introduced context dependent FgNER and proposed a set of heuristics for pruning labels that might not be relevant given the local context of the entity. Yogatama et al. yogatama2015embedding proposed an embedding based model where user-defined features and labels were embedded into a low dimensional feature space to facilitate information sharing among labels.\nShimaoka et al. shimaoka2016attentive proposed an attentive neural network model which used long short-term memory (LSTMs) to encode the context of the entity, then used an attention mechanism to allow the model to focus on relevant expressions in the entity mention's context. To learn entity representations, we propose a scheme which is potentially more generalizable.\nFurthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task.",

The race was conceived and directed by two members of the San Diego Track Club, Jack Johnstone and Don Shanahan. Johnstone recalls that he was a part of the 70s jogging craze in America and that after entering a few races he was not regaining his \"mediocre fitness\" despite having been a member of the 1957 Collegiate and AAU All-American swim teams. Then in 1973, Johnstone learned of the Dave Pain Birthday Biathlon, a 7.2 km (4.5 mi) run followed by what was billed as a quarter-mile (0.4 km) swim (the actual distance was only between 200 and 300 yards). The following year, after competing in the event for the second time and placing in the top ten, Johnstone desired more of this style of race and with equal emphasis on the swim. So he petitioned the chairman of the San Diego Track Club who told him he would add a race to the club calendar. But the rest of the race was up to Johnstone to organise, and at the same time he was to contact Don Shanahan so there wouldn't be too many \"weird\" races on the club schedule. Shanahan told Johnstone that he wanted to include a biking leg to the race; whilst hesitant Johnstone agreed to the addition. When naming the event the pair used the unofficially agreed naming system for multisport events, already used for pentathlon, heptathlon, and decathlon. So they used the Greek prefix tri (three) for the number of events, followed by the already familiar athlon, hence naming the event the Mission Bay Triathlon. It is worthy of note that neither founder had heard of the French events; both believed their race was a unique idea.\n\nOn Wednesday, September 25, 1974, the race started. It began with a run of a 4.8 km (3 mi) loop, followed by biking twice around Fiesta Island for a total of 8.0 km (5 mi). Entrants would then get off the bikes, take their shoes off and run into the water to swim to the mainland. That was followed by running in bare feet, then swimming again along the bay, then one last swim up to the entrance of Fiesta Island, and a final crawl up a steep dirt bank to finish. Most participants were not skilled swimmers, so Johnstone recruited his 13-year-old son to float on his surfboard and act as lifeguard. Some participants took longer than expected, and it began to get dark as they finished their swims. Shanahan recalls they pulled up a few cars and turned on the headlights so the athletes could see. Johnstone and Shanahan were surprised by the large number of entrants (46), mainly coming from local running clubs. Two notable entrants, Judy and John Collins, would four years later found the event which brought international attention to the new sport: the Hawaii Ironman.",

        "evidence": "Lexical analysis, syntactic analysis, semantic analysis, disclosure analysis and pragmatic analysis are five main steps in natural language processing BIBREF0 , BIBREF1 . While morphology is a basic task in lexical analysis of English, word segmentation is considered a basic task in lexical analysis of Vietnamese and other East Asian languages processing. This task is to determine borders between words in a sentence. In other words, it is segmenting a list of tokens into a list of words such that words are meaningful.\nWord segmentation is the primary step in prior to other natural language processing tasks i. e., term extraction and linguistic analysis (as shown in Figure 1). It identifies the basic meaningful units in input texts which will be processed in the next steps of several applications. For named entity recognization BIBREF2 , word segmentation chunks sentences in input documents into sequences of words before they are further classified in to named entity classes. For Vietnamese language, words and candidate terms can be extracted from Vietnamese copora (such as books, novels, news, and so on) by using a word segmentation tool. Conformed features and context of these words and terms are used to identify named entity tags, topic of documents, or function words. For linguistic analysis, several linguistic features from dictionaries can be used either to annotating POS tags or to identifying the answer sentences. Moreover, language models can be trained by using machine learning approaches and be used in tagging systems, like the named entity recognization system of Tran et al. BIBREF2 .\nMany studies forcus on word segmentation for Asian languages, such as: Chinese, Japanese, Burmese (Myanmar) and Thai BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . Approaches for word segmentation task are variety, from lexicon-based to machine learning-based methods. Recently, machine learning-based methods are used widely to solve this issue, such as: Support Vector Machine or Conditional Random Fields BIBREF7 , BIBREF8 . In general, Chinese is a language which has the most studies on the word segmentation issue. However, there is a lack of survey of word segmentation studies on Asian languages and Vietnamese as well. This paper aims reviewing state-of-the-art word segmentation approaches and systems applying for Vietnamese. This study will be a foundation for studies on Vietnamese word segmentation and other following Vietnamese tasks as well, such as part-of-speech tagger, chunker, or parser systems.\nThere are several studies about the Vietnamese word segmentation task over the last decade. Dinh et al. started this task with Weighted Finite State Transducer (WFST) approach and Neural Network approach BIBREF9 . In addition, machine learning approaches are studied and widely applied to natural language processing and word segmentation as well. In fact, several studies used support vector machines (SVM) and conditional random fields (CRF) for the word segmentation task BIBREF7 , BIBREF8 . Based on annotated corpora and token-based features, studies used machine learning approaches to build word segmentation systems with accuracy about 94%-97%.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation. A all sided review of word segmentation will help next studies on Vietnamese natural language processing tasks have an up-to-date guideline and choose the most suitable solution for the task. The remaining part of the paper is organized as follows. Section II discusses building corpus in Vietnamese, containing linguistic issues and the building progress. Section III briefly mentions methods to model sentences and text in machine learning systems. Next, learning models and approaches for labeling and segmenting sequence data will be presented in Section IV. Section V mainly addresses two existing toolkits, vnTokenizer and JVnSegmenter, for Vietnamese word segmentation. Several experiments based on mentioned approaches and toolkits are described in Section VI.

        "question": "What does the label Bi-LSTM reflect?",
        "answer": "The label Bi-LSTM reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nWe build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook.",

        "question": "What information is separated by their hierarchical intent annotation scheme?",
        "answer": "On-task and off-task information.",
        "evidence": "Considerable progress has been made building end-to-end dialog systems for collaborative tasks in which users cooperate with the system to achieve a common goal. Examples of collaborative tasks include making restaurant reservations and retrieving bus time-table information. Since users typically have clear and explicit intentions in collaborative tasks, existing systems commonly classify user utterances into pre-defined intents. In contrast, non-collaborative tasks are those where the users and the system do not strive to achieve the same goal. Examples of such tasks include deceiving attackers, persuading users to donate to a cause BIBREF1, and negotiating a product price BIBREF2, BIBREF3. In these tasks, users often perform complex actions that are beyond a simple set of pre-defined intents. In order to reach a common state, the user and the system need to build rapport and trust which naturally involves off-task content. Previous work did not model off-task content BIBREF2, which may have led to less optimal results. For example, in the persuasion task BIBREF1, users would ask the system “How do you feel about war?\" An example of an on-task system response that the system could have made is “Do you want to make a donation?\", which sticks to the task but neglects users' question. However, a better response to such an off-task question is “War is destructive and pitiless, but you can donate to help child victims of war.\" This response is better, as it has been found that users are more likely to end the conversation if the system neglects their questions BIBREF4. Therefore, we need to design a system that handles both on-task and off-task information appropriately and in a way that leads back to the system's goal.\nTo tackle the issue of incoherent system responses to off-task content, previous studies have built hybrid systems to interleave off-task and on-task content. BIBREF4 used a rule-based dialog manager for on-task content and a neural model for off-task content, and trained a reinforcement learning model to select between these two models based on the dialog context. However, such a method is difficult to train and struggles to generalize beyond the movie promotion task they considered. To tackle these problems, we propose a hierarchical intent annotation scheme that separates on-task and off-task information in order to provide detailed supervision. For on-task information, we directly use task-related intents for representation. Off-task information, on the other hand, is too general to categorize into specific intents, so we choose dialog acts that convey syntax information. These acts, such as “open question\" are general to all tasks.\nPrevious studies use template-based methods to maintain sentence coherence. However, rigid templates lead to limited diversity, causing the user losing engagement. On the other hand, language generation models can generate diverse responses but are bad at being coherent. We propose Multiple Intents and Semantic Slots Annotation Neural Network (MISSA) to combine the advantages of both template and generation models and takes advantage from the hierarchical annotation at the same time. MISSA follows the TransferTransfo framework BIBREF0 with three modifications: (i) We first concurrently predict user's, system's intents and semantic slots; (ii) We then perform conditional generation to improve generated response's coherence. Specifically, we generate responses conditioned on the above intermediate representation (intents and slots); (iii) Finally, we generate multiple responses with the nucleus sampling strategy BIBREF5 and then apply a response filter, which contains a set of pre-defined constraints to select coherent responses. The constraints in the filter can be defined according to specific task requirements or general conversational rules.\nTo enrich publicly available non-collaborative task datasets, we collect a new dataset AntiScam, where users defend themselves against attackers trying to collect personal information. As non-collaborative tasks are still relatively new to the study of dialog systems, there are insufficiently many meaningful datasets for evaluation and we hope this provides a valuable example. We evaluate MISSA on the newly collected AntiScam dataset and an existing PersuasionForGood dataset. Both automatic and human evaluations suggest that MISSA outperforms multiple competitive baselines.\nIn summary, our contributions include: (i) We design a hierarchical intent annotation scheme and a semantic slot annotation scheme to annotate the non-collaborative dialog dataset, we also propose a carefully-designed AntiScam dataset to facilitate the research of non-collaborative dialog systems. (ii) We propose a model that can be applied to all non-collaborative tasks, outperforming other baselines on two different non-collaborative tasks. (iii) We develop an anti-scam dialog system to occupy attacker's attention and elicit their private information for social good. Furthermore, we also build a persuasion dialog system to persuade people to donate to charities. We release the code and data.\nTo tackle these problems, we propose a hierarchical intent annotation scheme that separates on-task and off-task information in order to provide detailed supervision.",

        "evidence": "Despite the rapid progress of deep learning techniques on diverse supervised learning tasks, these models remain brittle to subtle shifts in the data distribution. Even when the permissible changes are confined to barely-perceptible perturbations, training robust models remains an open challenge. Following the discovery that imperceptible attacks could cause image recognition models to misclassify examples BIBREF0 , a veritable sub-field has emerged in which authors iteratively propose attacks and countermeasures.\nFor all the interest in adversarial computer vision, these attacks are rarely encountered outside of academic research. However, adversarial misspellings constitute a longstanding real-world problem. Spammers continually bombard email servers, subtly misspelling words in efforts to evade spam detection while preserving the emails' intended meaning BIBREF1 , BIBREF2 . As another example, programmatic censorship on the Internet has spurred communities to adopt similar methods to communicate surreptitiously BIBREF3 .\nIn this paper, we focus on adversarially-chosen spelling mistakes in the context of text classification, addressing the following attack types: dropping, adding, and swapping internal characters within words. These perturbations are inspired by psycholinguistic studies BIBREF4 , BIBREF5 which demonstrated that humans can comprehend text altered by jumbling internal characters, provided that the first and last characters of each word remain unperturbed.\nFirst, in experiments addressing both BiLSTM and fine-tuned BERT models, comprising four different input formats: word-only, char-only, word+char, and word-piece BIBREF6 , we demonstrate that an adversary can degrade a classifier's performance to that achieved by random guessing. This requires altering just two characters per sentence. Such modifications might flip words either to a different word in the vocabulary or, more often, to the out-of-vocabulary token UNK. Consequently, adversarial edits can degrade a word-level model by transforming the informative words to UNK. Intuitively, one might suspect that word-piece and character-level models would be less susceptible to spelling attacks as they can make use of the residual word context. However, our experiments demonstrate that character and word-piece models are in fact more vulnerable. We show that this is due to the adversary's effective capacity for finer grained manipulations on these models. While against a word-level model, the adversary is mostly limited to UNK-ing words, against a word-piece or character-level model, each character-level add, drop, or swap produces a distinct input, providing the adversary with a greater set of options.\nSecond, we evaluate first-line techniques including data augmentation and adversarial training, demonstrating that they offer only marginal benefits here, e.g., a BERT model achieving $90.3$ accuracy on a sentiment classification task, is degraded to $64.1$ by an adversarially-chosen 1-character swap in the sentence, which can only be restored to $69.2$ by adversarial training.\nThird (our primary contribution), we propose a task-agnostic defense, attaching a word recognition model that predicts each word in a sentence given a full sequence of (possibly misspelled) inputs. The word recognition model's outputs form the input to a downstream classification model. Our word recognition models build upon the RNN-based semi-character word recognition model due to BIBREF7 . While our word recognizers are trained on domain-specific text from the task at hand, they often predict UNK at test time, owing to the small domain-specific vocabulary. To handle unobserved and rare words, we propose several backoff strategies including falling back on a generic word recognizer trained on a larger corpus. Incorporating our defenses, BERT models subject to 1-character attacks are restored to $88.3$ , $81.1$ , $78.0$ accuracy for swap, drop, add attacks respectively, as compared to $69.2$ , $63.6$ , and $50.0$ for adversarial training\nFourth, we offer a detailed qualitative analysis, demonstrating that a low word error rate alone is insufficient for a word recognizer to confer robustness on the downstream task. Additionally, we find that it is important that the recognition model supply few degrees of freedom to an attacker. We provide a metric to quantify this notion of sensitivity in word recognition models and study its relation to robustness empirically. Models with low sensitivity and word error rate are most robust.\nThird (our primary contribution), we propose a task-agnostic defense, attaching a word recognition model that predicts each word in a sentence given a full sequence of (possibly misspelled) inputs.",

Second, they ignore the relevance of entity extraction and relation classification. Third, the pipelined framework results in low computational efficiency.",
        "evidence": "Recent years, great efforts have been made on extracting relational fact from unstructured raw texts to build large structural knowledge bases. A relational fact is often represented as a triplet which consists of two entities (subject and object) and semantic relation between them. Early works BIBREF0, BIBREF1, BIBREF2 mainly focused on the task of relation classification which assumes the entity pair are identified beforehand. This limits their practical application since they neglect the extraction of entities. To extract both entities and their relation, existing methods can be divided into two categories : the pipelined framework, which first uses sequence labeling models to extract entities, and then uses relation classification models to identify the relation between each entity pair; and the joint approach, which combines the entity model and the relation model through different strategies, such as constraints or parameters sharing.\n\nThe pipelined framework has the flexibility of integrating different data sources and learning algorithms, but their disadvantages are obvious. First, they suffer significantly from error propagation, the error of the entity extraction stage will be propagated to the relation classification stage. Second, they ignore the relevance of entity extraction and relation classification. As shown in Figure 2, entity contained in book title marks can be a song or book, its relation to a person can be singer or writer. Once the relationship has been confirmed, the entity type can be easily identified, and vice versa. For example, if we know the relationship is singer, then the entity type should be a song. Entity extraction and relation classification can benefit from each other so it will harm the performance if we consider them separately. Third, the pipelined framework results in low computational efficiency. After the entity extraction stage, each entity pair should be passed to the relation classification model to identify their relation. Since most entity pairs have no relation, this two-stage manner is inefficient.",

Here we consider a recently proposed generative model BIBREF22 that first encodes the context and question into a multi-perspective memory via four different neural matching layers, then decodes the answer using an attention-based model equipped with both copy and coverage mechanisms. The model is trained on our dataset for 15 epochs and we choose the model parameters that achieve the best BLEU-1 score on the development set.\nUnlike the aforementioned generative model, the Bi-Directional Attention Flow (BiDAF) BIBREF23 network learns to directly predict the answer span in the context. BiDAF first utilizes multi-level embedding layers to encode both the question and context, then uses bi-directional attention flow to get a query-aware context representation, which is further modeled by an RNN layer to make the span predictions. Since our TweetQA does not have labeled answer spans as in SQuAD, we need to use the human-written answers to retrieve the answer-span labels for training. To get the approximate answer spans, we consider the same matching approach as in the query matching baseline. But instead of using questions to do matching, we use the human-written answers to get the spans that achieve the best BLEU-1 scores.\nThis is another extractive RC model that benefits from the recent advance in pretrained general language encoders BIBREF24 , BIBREF25 .

        "answer": "The 2023 MLB season might break the total runs scored record in a regular season due to three rule changes.. \n\n1. Base sizes going from 15 inches per side to 18 inches per side. The increase in base size promotes safer stealing conditions for runners allowing them to more easily avoid contact with fielders. Also, the larger base surface area will help runners from \"over-sliding\" on the base leading to an out.\n\n2. Two disengagements per plate appearance. Pitchers are only allowed two forms of disengagement which will reduce the number of pickoff attempts and mound step offs. In the event of a third disengagement, the pitcher will be charged with a balk leading to a base advancement for any runner on base or a ball given to the batter.\n\n3. Eliminating the shift. When the time a pitch is thrown, all four infielders must be on the infield dirt or grass with two on each side of second base. This new rule will increase batting averages, hits per game, and more doubles.",

Other possible factors in the decline include disturbance and pollution from ecotourism and fishing, egg-harvesting, and predation and competition from subantarctic fur seals (Arctophoca tropicalis). Surveys show that the birds are at risk of infection by goose barnacles. House mice (Mus musculus) have been introduced into their environment by human sea expeditions. The mice have proven to be invasive, and consume northern rockhopper eggs, as well as hunt their young. In order to preserve the birds, a culling of the mice is being considered.

It was commissioned in 1631 by the fifth Mughal emperor, Shah Jahan (r. 1628–1658) to house the tomb of his favourite wife, Mumtaz Mahal; it also houses the tomb of Shah Jahan himself. The tomb is the centrepiece of a 17-hectare (42-acre) complex, which includes a mosque and a guest house, and is set in formal gardens bounded on three sides by a crenellated wall.\n\nConstruction of the mausoleum was essentially completed in 1643, but work continued on other phases of the project for another 10 years. The Taj Mahal complex is believed to have been completed in its entirety in 1653 at a cost estimated at the time to be around ₹32 million, which in 2020 would be approximately ₹70 billion (about US $1 billion). The construction project employed some 20,000 artisans under the guidance of a board of architects led by Ustad Ahmad Lahauri, the emperor’s court architect. Various types of symbolism have been employed in the Taj to reflect natural beauty and divinity.\n\nThe Taj Mahal was designated as a UNESCO World Heritage Site in 1983 for being \"the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage\". It is regarded by many as the best example of Mughal architecture and a symbol of India's rich history.

        "question": "Are trained word embeddings used for any other NLP task?",
        "answer": "No.",
        "evidence": "In this era of the information age, the existence of LRs plays a vital role in the digital survival of natural languages because the NLP tools are used to process a flow of un-structured data from disparate sources. It is imperative to mention that presently, Sindhi Persian-Arabic is frequently used in online communication, newspapers, public institutions in Pakistan and India. Due to the growing use of Sindhi on web platforms, the need for its LRs is also increasing for the development of language technology tools. But little work has been carried out for the development of resources which is not sufficient to design a language independent or machine learning algorithms. The present work is a first comprehensive initiative on resource development along with their evaluation for statistical Sindhi language processing. More recently, the NN based approaches have produced a state-of-the-art performance in NLP by exploiting unsupervised word embeddings learned from the large unlabelled corpus. Such word embeddings have also motivated the work on low-resourced languages. Our work mainly consists of novel contributions of resource development along with comprehensive evaluation for the utilization of NN based approaches in SNLP applications. The large corpus obtained from multiple web resources is utilized for the training of word embeddings using SG, CBoW and Glove models. The intrinsic evaluation along with comparative results demonstrates that the proposed Sindhi word embeddings have accurately captured the semantic information as compare to recently revealed SdfastText word vectors. The SG yield best results in nearest neighbors, word pair relationship and semantic similarity. The performance of CBoW is also close to SG in all the evaluation matrices. The GloVe also yields better word representations; however SG and CBoW models surpass the GloVe model in all evaluation matrices. Hyperparameter optimization is as important as designing a new algorithm. The choice of optimal parameters is a key aspect of performance gain in learning robust word embeddings. Moreover, We analysed that the size of the corpus and careful preprocessing steps have a large impact on the quality of word embeddings. However, in algorithmic perspective, the character-level learning approach in SG and CBoW improves the quality of representation learning, and overall window size, learning rate, number of epochs are the core parameters that largely influence the performance of word embeddings models. Ultimately, the new corpus of low-resourced Sindhi language, list of stop words and pretrained word embeddings along with empirical evaluation, will be a good supplement for future research in SSLP applications. In the future, we aim to use the corpus for annotation projects such as parts-of-speech tagging, named entity recognition. The proposed word embeddings will be refined further by creating custom benchmarks and the extrinsic evaluation approach will be employed for the performance analysis of proposed word embeddings. Moreover, we will also utilize the corpus using Bi-directional Encoder Representation Transformer BIBREF13 for learning deep contextualized Sindhi word representations. Furthermore, the generated word embeddings will be utilized for the automatic construction of Sindhi WordNet.\nIn the future, we aim to use the corpus for annotation projects such as parts-of-speech tagging, named entity recognition.\nFurthermore, the generated word embeddings will be utilized for the automatic construction of Sindhi WordNet.",

Electric currents and the magnetic moments of elementary particles giving rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ferro- refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4.\n\nAll substances exhibit some type of magnetism. Magnetic materials are classified according to their bulk susceptibility. Ferromagnetism is responsible for most of the effects of magnetism encountered in everyday life, but there are actually several types of magnetism. Paramagnetic substances, such as aluminium and oxygen, are weakly attracted to an applied magnetic field; diamagnetic substances, such as copper and carbon, are weakly repelled; while antiferromagnetic materials, such as chromium and spin glasses, have a more complex relationship with a magnetic field. The force of a magnet on paramagnetic, diamagnetic, and antiferromagnetic materials is usually too weak to be felt and can be detected only by laboratory instruments, so in everyday life, these substances are often described as non-magnetic.",

        "evidence": "Knowledge sharing platforms such as Quora and Zhihu emerge as very convenient tools for acquiring knowledge. These question and answer (Q&A) platforms are newly emerged communities about knowledge acquisition, experience sharing and social networks services (SNS).\nUnlike many other Q&A platforms, Zhihu platform resembles a social network community. Users can follow other people, post ideas, up-vote or down-vote answers, and write their own answers. Zhihu allows users to keep track of specific fields by following related topics, such as “Education”, “Movie”, “Technology” and “Music”. Once a Zhihu user starts to follow a specific topic or a person, the related updates are automatically pushed to the user's feed timeline.\nAlthough these platforms have exploded in popularity, they face some potential problems. The key problem is that as the number of users grows, a large volume of low-quality questions and answers emerge and overwhelm users, which make users hard to find relevant and helpful information.\nZhihu Live is a real-time voice-answering product on the Zhihu platform, which enables the speakers to share knowledge, experience, and opinions on a subject. The audience can ask questions and get answers from the speakers as well. It allows communication with the speakers easily and efficiently through the Internet. Zhihu Live provides an extremely useful reward mechanism (like up-votes, following growth and economic returns), to encourage high-quality content providers to generate high-level information on Zhihu platform.\nHowever, due to the lack of efficient filter mechanism and evaluation schemes, many users suffer from lots of low-quality contents, which affects the service negatively. Recently, studies on social Q&A platforms and knowledge sharing are rising and have achieved many promising results. Shah et al. BIBREF0 propose a data-driven approach with logistic regression and carefully designed hand-crafted features to predict the answer quality on Yahoo! Answers. Wang et al. BIBREF1 illustrate that heterogeneity in the user and question graphs are important contributors to the quality of Quora's knowledge base. Paul et al. BIBREF2 explore reputation mechanism in quora through detailed data analysis, their experiments indicate that social voting helps users identify and promote good content but is prone to preferential attachment. Patil et al. BIBREF3 propose a method to detect experts on Quora by their activity, quality of answers, linguistic characteristics and temporal behaviors, and achieves 97% accuracy and 0.987 AUC. Rughinis et al. BIBREF4 indicate that there are different regimes of engagement at the intersection of the technological infrastructure and users' participation in Quora.\nAll of these works are mainly focused on answer ranking and answer quality evaluation. But there is little research achievement about quality evaluation in voice-answering areas. In this work, we present a data-driven approach for quality evaluation about Zhihu Live, by consuming the dataset we collected to gather knowledge and insightful conclusion. The proposed data-driven approach includes data collection, storage, preprocessing, data analysis, and predictive analysis via machine learning. The architecture of our data-driven method is shown in Fig. FIGREF3 . The records are crawled from Zhihu Live official website and stored in MongoDB. Data preprocessing methods include cleaning and data normalization to make the dataset satisfy our target problem. Descriptive data analysis and predictive analysis are also conducted for deeper analysis about this dataset.\nThe main contributions of this paper are as follows: (1) We release a public benchmark dataset which contains 7242 records and 286,938 text comments about Zhihu Live. Detailed analysis about the dataset is also discussed in this paper. This dataset could help researchers verify their ideas in related fields. (2) By analyzing this dataset, we gain several insightful conclusion about Zhihu Live. (3) We also propose a multi-branched neural network (MTNet) to evaluate Zhihu Lives' scores. The superiority of our proposed model is demonstrated by comparing performance with other mainstream regressors.\nThe rest of this paper is organized as follows: Section 2 describes detailed procedures of ZhihuLive-DB collection, and descriptive analysis. Section 3 illustrates our proposed MTNet. In section 4, we give a detailed description of experiments, and the last section discusses the conclusion of this paper and future work.\nThe proposed data-driven approach includes data collection, storage, preprocessing, data analysis, and predictive analysis via machine learning.",

        "evidence": "Affordance-aware navigation is a major challenge in solving complex and long-horizon indoor tasks such as ALFRED with both navigation and object interactions. Specifically, given each object of interest in the scene, the agent is required to not only find and approach it but also end up at a pose (x, y, r, h), that is feasible for subsequent interactions with the object. For instance, to open a fridge, the robot should approach the fridge closely enough (so the door is within reach), look at it (so that the fridge is in the field of view), and leave enough room to open the door. To solve a long-horizon task involving multiple navigation and object interaction subgoals, it is natural to use an explicit semantic map, either 2D or 3D, of the environment (similar to Neural Active SLAM Chaplot et al. (2020a)), together with model-based planning (e.g. as in). This line of work tends to generalize better than models that directly learn mappings from human instructions to navigation & interaction actions (e.g., E.T.). With perfect knowledge of the environment, it is possible to achieve (nearly) perfect performance. In practice, however, the semantic map acquired at inference time is usually far from ideal, primarily due to Incompleteness (missing information due to insufficient exploration of the scene) and Inaccuracy (erroneous object location prediction on the map, especially for small objects).\nTo improve exploration performance, we propose a multimodal module that, at each step, predicts an exploration action a ∈ {MoveAhead, RotateLeft, RotateRight} by taking visual observations & actions in the past, step-by-step language instructions, and the explored area map which indicates where the agent has visited. We show that, compared to existing model-based approaches on ALFRED (e.g., which applies random exploration), our use of lowlevel language instructions leads to more efficient exploration. The proposed exploration module operates at the subgoal level and only predicts exploration actions (in contrast to E.T. which directly predicts actions for the entire task). The extra modality (the explored area) facilitates exploration by providing the agent with explicit spatial information. We illustrate the exploration module in Figure, elaborate its details in Section 4.3, and empirically demonstrate its advantages in Section 5.\nTo improve exploration performance, we propose a multimodal module that, at each step, predicts an exploration action a ∈ {MoveAhead, RotateLeft, RotateRight} by taking visual observations & actions in the past, step-by-step language instructions, and the explored area map which indicates where the agent has visited.****The Extra Modality: Explored Area The extra modality introduced in our multimodal exploration module essentially tracks the action history explicitly and geometrically.",

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nOur main contributions are:  • Our study demonstrates the necessity and effectiveness of exploiting the intermediate gradients for estimating word importance. • We find that word importance is useful for understanding NMT by identifying undertranslated words.  • We provide empirical support for the design principle of NMT architectures: essential inductive bias (e.g., language characteristics) should be considered for model design.",

BIBREF0 Detecting, assessing, and preventing these events are the tasks of pharmacovigilance. In the pre-trial and trial stages of drug development, the number of people taking a drug is carefully controlled, and the collection of ADR data is centralized. However, after the drug is available widely, post-marketing surveillance often requires the collection and merging of data from disparate sources, BIBREF1 including patient-initiated spontaneous reporting. Unfortunately, adverse reactions to drugs are grossly underreported to health professionals. BIBREF2 , BIBREF3 Considerable issues with patient-initiated reporting have been identified, including various types of reporting biases and causal attributions of adverse events. BIBREF4 , BIBREF5 , BIBREF6 Nevertheless, a large number of people, freely and spontaneously, report ADRs on social media. The potential availability of inexpensive, large-scale, and real-time data on ADRs makes social media a valuable resource for pharmacovigilance.\nInformation required for pharmacovigilance includes a reported adverse drug reaction, a linked drug referred to by its full, abbreviated, or generic name, and an indication whether it was the social media post author that experienced the adverse event. However, there are considerable challenges in automatically extracting this information from free-text social media data. Social media texts are often short and informal, and include non-standard abbreviations and creative language. Drug names or their effects may be mis-spelled; they may be used metaphorically (e.g., Physics is like higher level maths on steroids). Drug names might have other non-drug related meanings (e.g., ecstasy). An adverse event may be negated or only expected (e.g., I bet I'll be running to the bathroom all night), or it may not apply to the author of the post at all (e.g., a re-tweet of a press release).\nThe shared task challenge organized as part of the AMIA-2017 Workshop on Social Media Mining for Health Applications (SMM4H) focused on Twitter data and had three tasks: Task 1 - recognizing whether a tweet is reporting an adverse drug reaction, Task 2 - inferring whether a tweet is reporting the intake of a medication by the tweeter, and Task 3 - mapping a free-text ADR to a standardized MEDDRA term. Our team made submissions for Task 1 and Task 2. For both tasks, we trained Support Vector Machine classifiers using a variety of surface-form, sentiment, and domain-specific features. Handling class imbalance with under-sampling was particularly helpful. Our submissions obtained F-scores of 0.435 on Task 1 and 0.673 on Task 2, resulting in a rank of first and third, respectively.

        "evidence": "Recently, there is a surge of excitement in adding numerous new domains to conversational agents such as Alexa, Google Assistant, Cortana and Siri to support a myriad of use cases. However, building a slot tagger, which is a key component for natural language understanding (NLU) BIBREF0 , for a new domain requires massive amounts of labeled data, hindering rapid development of new skills. To address the data-intensiveness problem, domain adaptation approaches have been successfully applied. Previous approaches are roughly categorized into two groups: data-driven approaches BIBREF1 , BIBREF2 and model-driven approaches BIBREF3 , BIBREF4 .\nIn the data-driven approach, new target models are trained by combining target domain data with relevant data from a repository of arbitrary labeled datasets using domain adaptation approaches such as feature augmentation BIBREF1 . A disadvantage of this approach is the increase in training time as the amount of reusable data grows. The reusable data might contain hundreds of thousands of samples, making iterative refinement prohibitive. In contrast, the model-driven approach utilizes “expert\" models for summarizing the data for reusable slots BIBREF3 , BIBREF4 . The outputs of the expert models are directly used when training new domains, allowing for faster training. A drawback of this approach is that it requires explicit concept alignments which itself is not a trivial task, potentially missing lots of reusable concepts. Additionally, it's not easy to generalize these models to new, unseen slots.\nIn this paper, we present a new domain adaptation technique for slot tagging inspired by recent advances in zero-shot learning. Traditionally, slot tagging is formulated as a sequence labeling task using the BIO representation (Figure 1 ). Our approach formulates this problem as detecting spans that contain values for each slot as shown in Figure 1 . For implicit transfer of reusable concepts across domains, we represent slots in a shared latent semantic space by embedding the slot description. With the shared latent space, domain adaptation can simply be done by fine-tuning a base model, which is trained on massive data, with a handful of target domain data without any explicit concept alignments. A similar idea of utilizing zero-shot learning for slot tagging has been proven to work in semi-supervised settings BIBREF5 . Our zero-shot model architecture differs from this by adding: 1) an attention layer to produce the slot-aware representations of input words, 2) a CRF layer to better satisfy global consistency constraints, 3) character-level embeddings to incorporate morphological information. Despite its simplicity, we show that our model outperforms all existing methods including the previous zero-shot learning approach in domain adaptation settings.\nWe first describe our approach called Zero-Shot Adaptive Transfer model (ZAT) in detail. We then describe the dataset we used for our experiments. Using this data, we conduct experiments comparing our ZAT model with a set of state-of-the-art models: Bag-of-Expert (BoE) models and their non-expert counterparts BIBREF4 , and the Concept Tagger model BIBREF5 , showing that our model can lead to significant F1-score improvements. This is followed by an in-depth analysis of the results. We then provide a survey of related work and concluding remarks.\nUsing this data, we conduct experiments comparing our ZAT model with a set of state-ofthe-art models: Bag-of-Expert (BoE) models and their nonexpert counterparts (Jha et al. 2018), and the Concept Tagger model (Bapna et al. 2017), showing that our model can lead to significant F1-score improvements.",

        "evidence": "The centaurs were usually said to have been born of Ixion and Nephele. As the story goes, Nephele was a cloud made into the likeness of Hera in a plot to trick Ixion into revealing his lust for Hera to Zeus. Ixion seduced Nephele and from that relationship centaurs were created. Another version, however, makes them children of Centaurus, a man who mated with the Magnesian mares. Centaurus was either himself the son of Ixion and Nephele (inserting an additional generation) or of Apollo and the nymph Stilbe. In the latter version of the story, Centaurus's twin brother was Lapithes, ancestor of the Lapiths.\n\nAnother tribe of centaurs was said to have lived on Cyprus. According to Nonnus, they were fathered by Zeus, who, in frustration after Aphrodite had eluded him, spilled his seed on the ground of that land. \n\nThere were also the Lamian Pheres, twelve rustic daimones (spirits) of the Lamos river. They were set by Zeus to guard the infant Dionysos, protecting him from the machinations of Hera, but the enraged goddess transformed them into ox-horned Centaurs. The Lamian Pheres later accompanied Dionysos in his campaign against the Indians.\n\nThe centaur's half-human, half-horse composition has led many writers to treat them as liminal beings, caught between the two natures they embody in contrasting myths; they are both the embodiment of untamed nature, as in their battle with the Lapiths (their kin), and conversely, teachers like Chiron.",

        "question": "What model does the paper develop?",
        "answer": "A sifted multi-task learning model with filtering mechanism to detect fake news by joining stance detection task.",
        "evidence": "In recent years, the proliferation of fake news with various content, high-speed spreading, and extensive influence has become an increasingly alarming issue. A concrete instance was cited by Time Magazine in 2013 when a false announcement of Barack Obama's injury in a White House explosion “wiped off 130 Billion US Dollars in stock value in a matter of seconds\". Other examples, an analysis of the US Presidential Election in 2016 BIBREF0 revealed that fake news was widely shared during the three months prior to the election with 30 million total Facebook shares of 115 known pro-Trump fake stories and 7.6 million of 41 known pro-Clinton fake stories. Therefore, automatically detecting fake news has attracted significant research attention in both industries and academia.\nMost existing methods devise deep neural networks to capture credibility features for fake news detection. Some methods provide in-depth analysis of text features, e.g., linguistic BIBREF1, semantic BIBREF2, emotional BIBREF3, stylistic BIBREF4, etc. On this basis, some work additionally extracts social context features (a.k.a. meta-data features) as credibility features, including source-based BIBREF5, user-centered BIBREF6, post-based BIBREF7 and network-based BIBREF8, etc. These methods have attained a certain level of success. Additionally, recent researches BIBREF9, BIBREF10 find that doubtful and opposing voices against fake news are always triggered along with its propagation. Fake news tends to provoke controversies compared to real news BIBREF11, BIBREF12. Therefore, stance analysis of these controversies can serve as valuable credibility features for fake news detection.\nThere is an effective and novel way to improve the performance of fake news detection combined with stance analysis, which is to build multi-task learning models to jointly train both tasks BIBREF13, BIBREF14, BIBREF15. These approaches model information sharing and representation reinforcement between the two tasks, which expands valuable features for their respective tasks. However, prominent drawback to these methods and even typical multi-task learning methods, like the shared-private model, is that the shared features in the shared layer are equally sent to their respective tasks without filtering, which causes that some useless and even adverse features are mixed in different tasks, as shown in Figure FIGREF2(a). By that the network would be confused by these features, interfering effective sharing, and even mislead the predictions.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure FIGREF2(b)) to detect fake news by joining stance detection task. Specifically, we introduce a selected sharing layer into each task after the shared layer of the model for filtering shared features. The selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks. Besides, to better capture long-range dependencies and improve the parallelism of the model, we apply transformer encoder module BIBREF16 to our model for encoding input representations of both tasks. Experimental results reveal that the proposed model outperforms the compared methods and gains new benchmarks.\nIn summary, the contributions of this paper are as follows:\nWe explore a selected sharing layer relying on gate mechanism and attention mechanism, which can selectively capture valuable shared features between tasks of fake news detection and stance detection for respective tasks.\nThe transformer encoder is introduced into our model for encoding inputs of both tasks, which enhances the performance of our method by taking advantages of its long-range dependencies and parallelism.\nExperiments on two public, widely used fake news datasets demonstrate that our method significantly outperforms previous state-of-the-art methods.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure FIGREF2(b)) to detect fake news by joining stance detection task.",

        "evidence": "We present an information extraction architecture that augments a candidate-generating parser with a deep neural network. The candidate-generating parser may leverage constraints. At the same time, the architecture gains the neural networks's ability to leverage large amounts of data to learn complex features that are tuned for the application at hand. Our method assumes the existence of a potentially noisy source of supervision INLINEFORM0 , e.g. via consistency checks of extracted data against existing databases, or via human interaction. This supervision is used to train the neural network.\nOur extraction system has three advantages over earlier work on information extraction with deep neural networks BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 :\nOur system leverages “free” data to train a deep neural network, and does not require large-scale manual annotation. The network is trained with noisy supervision provided by measures of consistency with existing databases (e.g. an extraction ts_tick_abs (US_Unemployment, 49%) would be implausible given recent US employment history). With slight modifications, our pipeline could be trained with supervision from human interaction, such as clicks on online advertisements. Learning without explicit annotations is critical in applications where large-scale manual annotation would be prohibitively expensive.\nIf an extractor for the given application has already been built, the neural network boosts its accuracy without the need to re-engineer or discard the existing solution. Even for new systems, the decoupling of candidate-generation and the neural network offers advantages: the candidate-generating parser can easily enforce contraints that would be difficult to support in an algorithm relying entirely on a neural network. Note that, in particular, a carefully engineered candidate-generating parser enforces constraints intelligently, and can in many instances eliminate the need to evaluate computationally expensive constraints, e.g. API calls.\nWe encode the candidate-generating parser's document annotations character-by-character into vectors INLINEFORM0 that also include a one-hot encoding of the character itself. We believe that this encoding makes it easier for the network to learn character-level characteristics of the entities in the semantic relation. Moreover, our encoding lends itself well to processing both by recurrent architectures (processing character-by-character input vectors INLINEFORM1 ) and convolutional architectures (performing 1D convolutions over an input matrix whose columns are vectors INLINEFORM2 ).\nIn a production setting, the neural architecture presented here reduced the number of false positive extractions in financial information extraction application by INLINEFORM0 relative to a mature system developed over the course of several years.\nAt the same time, the architecture gains the neural networks's ability to leverage large amounts of data to learn complex features that are tuned for the application at hand.",

        "question": "Please give me a short bulleted list of the top achievements John Wooden had as a coach for the UCLA men's basketball team.",
        "evidence": "In the 1948–1949 season, Wooden was hired by the University of California, Los Angeles, to be the fourth basketball coach in the school's history. He succeeded Fred Cozens, Caddy Works, and Wilbur Johns; Johns became the school's athletic director. Wooden signed a three-year contract for $6,000 in the first year. Prior to being hired at UCLA, he had been pursued for the head coaching position at the University of Minnesota, and it was his and his wife's desire to remain in the Midwest, but inclement weather in Minnesota prevented Wooden from receiving the scheduled phone offer from the Golden Gophers. Thinking that they had lost interest, Wooden instead accepted the head coaching job with the Bruins. Officials from the University of Minnesota contacted Wooden immediately after he accepted the position at UCLA, but he declined their offer because he had already given his word to UCLA.\n\nWooden had immediate success, fashioning the mark of the rarest of coaches, an \"instant turnaround\" for an undistinguished, faltering program. Part of this success was due to his unique offensive system, the same system that countless coaches use today. John Wooden stated, \"I believe my system is perfectly suited to counter all the modern defenses I have seen, and that includes run-and-jump, 1–3–1 trapping, box-and-one, triangle-and-two, and switching man-to-man.\"\n\nPrior to Wooden's arrival at UCLA, the basketball program had only had two conference championship seasons in the previous 18 years. In his first season, he took a Bruins team that had posted a 12–13 record the previous year and transformed it into a Pacific Coast Conference (PCC) Southern Division champion with a 22–7 record, the most wins in a season for UCLA since the school started playing basketball in 1919. He surpassed that number the next season with 24–7 and a second division title and overall conference title in 1950, and would add two more in his first four years. Up to that time, UCLA had collected a total of two division titles since the PCC began divisional play, and had not won a conference title of any sort since winning the Southern California Intercollegiate Athletic Conference in 1927.\n\n\nWooden in 1960\nIn spite of these achievements, Wooden reportedly did not initially enjoy his position, and his wife did not favor living in Los Angeles. When Mel Taube left Purdue in 1950, Wooden's inclination was to return to West Lafayette and finally accept the head coaching job there. He was ultimately dissuaded when UCLA officials reminded him that it was he who had insisted upon a three-year commitment during negotiations in 1948. Wooden felt that leaving UCLA prior to the expiration of his contract would be tantamount to breaking his word, even though Purdue offered more money, a car and housing.\n\nBy the 1955–56 season, Wooden had established a record of sustained success at UCLA. That year, he guided the team to its first undefeated PCC conference title and a 17-game winning streak that came to an end only at the hands of Phil Woolpert's University of San Francisco team (who had Bill Russell and K.C. Jones) that eventually won the 1956 NCAA tournament. However, UCLA was unable to advance from this level over the immediately ensuing seasons, finding itself unable to return to the NCAA Tournament, as the Pete Newell-coached teams of the California Golden Bears took control of the conference and won the 1959 NCAA tournament. Also hampering the fortunes of Wooden's team during that time period was a probation that was imposed on all UCLA sports teams in the aftermath of a scandal that involved illegal payments made to players on the school's football team. The probation was also extended to three additional schools: the University of Southern California, California and Stanford. The scandal resulted in the dismantling of the PCC conference.\n\nBy the 1961–1962 season, the probation was no longer in place and Wooden returned his team to the top of the conference. This time, however, they would take the next step, and in so doing, unleash a run of dominance unparalleled in the history of college basketball. UCLA reached the Final Four of the NCAA tournament for the first time in school history. A narrow loss, due largely to a controversial foul call in a 1962 semi-final game against Ed Jucker's eventual national champion Cincinnati team, convinced Wooden that his Bruins were ready to contend for national championships. Two seasons later in 1964, the final piece of the puzzle fell into place when assistant coach Jerry Norman persuaded Wooden that the team's small-sized players and fast-paced offense would be complemented by the adoption of a zone press defense, which increased the probability of turnovers by the opposing team. The result was a dramatic increase in scoring, giving UCLA a powerhouse team that went 30–0 on its way to the school's first basketball national championship and first undefeated season as the Bruins beat Vic Bubas' taller and slower racially segregated Duke team 98–83 in the final. Walt Hazzard fouled out of the game late in the second half on a player control foul, but this was irrelevant when he cut down the net in celebration and was named tournament most valuable player. Gail Goodrich, Keith Erickson, Fred Slaughter, and Jack Hirsch contributed to the UCLA win. With no player taller than 6 feet, 5 inches, the Bruins' speed and zone press forced 29 turnovers and nullified the height advantage of Duke's Hack Tison and Jay Buckley, two 6-foot, 10-inch players.\n\nIn the 1964-1965 campaign, the defending NCAA champions got off to an ominous start when UCLA lost to Illinois by 27 points in its opening game. It was all uphill after that as the squad repeated as national champions with Gail Goodrich, Kenny Washington, and Doug McIntosh. The Bruins upended Dave Strack's Michigan team 91–80 in the finals of the NCAA tournament. Goodrich shared Player of the Year honors with Princeton's Bill Bradley. The 1966 squad was denied a chance at a triple crown when it finished second to Oregon State in the Athletic Association of Western Universities (now the Pac-12). UCLA was ineligible to play in the NCAA tournament that year because in those days only conference champions received a bid to the tournament. The Bruins' 1967 incarnation returned with a vengeance with sophomore star Alcindor, reclaiming not only the conference title, but the national crown with another 30–0 season, and then retaining it every season but one until Wooden's retirement immediately following the 1975 NCAA championship.\n\nThe resurgence of the Bruins under Wooden made it obvious that they needed a new home. Since 1932, the Bruins had played at the Men's Gym. It normally seated 2,400, but had been limited to 1,500 since 1955 by order of the city fire marshal. This forced the Bruins to move games to Pan Pacific Auditorium, the Los Angeles Memorial Sports Arena and other venues around Los Angeles when they were expected to attract larger crowds—something that happened fairly often after the Bruins' first national title. At Wooden's urging, a much larger on-campus facility, Pauley Pavilion, was built in time for the 1965–66 season. The building in Westwood was christened on November 27, 1965, in a special game that pitted the UCLA varsity against the UCLA freshmen. It was Lew Alcindor's (later Kareem Abdul-Jabbar) freshman season (freshmen were ineligible to play on the varsity in those days). UCLA was the defending national champion and ranked number 1 in the pre-season poll. The freshmen easily won the game by a score of 75–60. It was a powerful indication of things to come.\n\nA rule change was instituted for the 1967–1968 season, primarily because of Alcindor's towering play near the basket. The dunk shot was outlawed and would not be reinstated until the 1976–1977 season, which was shortly after Wooden's retirement. This was at least the second time that the rules committee had initiated change in response to the domination of a superstar player; in 1944, the goaltending rule was instituted to counter George Mikan's dominant defensive play near the basket. In January, UCLA took its 47-game winning streak to the Astrodome in Houston, where the Bruins met Guy Lewis' Houston squad, who had Elvin Hayes and Ken Spain, in the Game of the Century in the nation's first nationally televised regular season college basketball game. Houston upset UCLA 71–69, as Hayes scored 39 points. In a post-game interview, Wooden said, \"We have to start over.\" UCLA went undefeated the rest of the year and thrashed Houston 101–69 in the semi-final rematch of the NCAA tournament en route to the national championship. Sports Illustrated ran the front cover headline Lew's Revenge. The rout of Houston. UCLA limited Hayes to only 10 points; he had been averaging 37.7 points per game. Wooden credited Norman for devising the diamond-and-one defense that contained Hayes. The Game of the Century is also remembered for an incident involving Wooden and Edgar Lacy. Lacy was ineffective on defense against Elvin Hayes, and Wooden benched him after 11 minutes. Lacy never re-entered the game. Furious with Wooden, Lacy quit the team three days later, telling the Los Angeles Times \"I've never enjoyed playing for that man.\" UCLA's talent during the 1968 NCAA tournament was so overwhelming that they placed four players on the All-Tournament team. In addition to Alcindor, Lucius Allen, Mike Warren, and \"Lefty\" Lynn Shackelford were given accolades. Kenny Heitz was also a member of UCLA's 1968 team.\n\nLew Alcindor finished his career at UCLA in 1969 with a third consecutive national championship when the Bruins beat George King's Purdue team 92–72 in the title game. The three straight titles were matched by three consecutive MVP awards in the tournament as Alcindor established himself as college basketball's superstar during the three-peat performance. Alcindor and Wooden would continue their communication even after he left UCLA. In 2017, Jabbar wrote a book, \"Coach Wooden and Me\", which details their long-standing friendship.\n\nA sportswriter commented that everybody outside of UCLA would be happy that glorious day in June when Alcindor finally graduated and college basketball could go back to the routine method of determining a national champion. This prophecy would prove to be ludicrous over the next six years. The 1970 squad proved that nobody was indispensable to the success of the UCLA program, not even Alcindor, as Sidney Wicks, Henry Bibby, Curtis Rowe, John Vallely, and Kenny Booker carried the Bruins to their fourth consecutive NCAA title with an 80–69 win over upstart Jacksonville, coached by Joe Williams. Wicks and Rowe double teamed 7-foot Artis Gilmore on defense and shut down the high-powered Jacksonville offense, which had been averaging 100 points per game. Gilmore and 5'10\" Rex Morgan had been dubbed \"Batman and Robin\" by the press.\n\nIn the 1971 NCAA championship game, Steve Patterson outscored Howard Porter of Jack Kraft's scandal-plagued Villanova squad as UCLA won 68–62. The following year, UCLA had its closest game in all of Wooden's 10 championships, beating Hugh Durham's Florida State team 81–76 to take the 1972 title. After the game, Bill Walton said, \"We didn't play well.\"\n\n\nWooden with Digger Phelps in 1973, after UCLA beat Notre Dame for their NCAA-record 61st straight win\nThe 1972–1973 season was one of the most memorable campaigns in the history of UCLA basketball. Freshmen became eligible to play varsity ball again, and the Bruins went 30–0 and stretched their winning streak to a record 75 straight in breezing through the NCAA tournament by blowing out Gene Bartow's Memphis State team 87–66 in the final, as Bill Walton hit an incredible 21 of 22 field goal attempts. Walton and Wooden were everybody's Player and Coach of the Year again. Keith Wilkes, Greg Lee, and Larry Hollyfield were members of that team, and Wilkes would go on to win four NBA championships as well.\n\nUCLA's two big streaks came to an end during the 1973–1974 season. In January, the winning streak stopped at 88 games when Digger Phelps's Notre Dame squad upended the Bruins 71–70 in South Bend. Two months later, Norm Sloan's North Carolina State team defeated UCLA 80–77 in double overtime in the semifinals of the NCAA tournament. David Thompson was NC State's All-American, and Tom Burleson did an excellent job on defense against Bill Walton. UCLA had beaten the Wolfpack by 18 points early in the season, but things were different when they met in March.\n\nWooden coached what would prove to be his final game in Pauley Pavilion on March 1, 1975, a 93–59 victory over Stanford. Four weeks later, following a 75–74 overtime victory over former player and former assistant coach Denny Crum and Louisville in the 1975 NCAA Tournament semifinal game, Wooden announced that he would retire at age 64 immediately after the championship game. His legendary coaching career concluded triumphantly when Richard Washington and David Meyers combined for 52 points as UCLA responded with a 92–85 win over Joe B. Hall and Kentucky to claim Wooden's first career coaching victory over the Wildcats and his unprecedented 10th national championship. Marques Johnson and Andre McCarter were also key contributors on Wooden's final championship team. The success of Wooden's last team was particularly impressive because it had no marquee stars such as Alcindor, Walton, Hazzard, and Goodrich; the team was a group of rugged opportunists.\n\nAndy Hill, who was on three Bruin teams under Wooden that won NCAA championships from 1970 to 1972, decades later co-wrote with Wooden the 2001 book Be Quick—But Don't Hurry! Finding Success in the Teachings of a Lifetime. The bestseller details how Hill applied his experience as a player under Wooden to achieve success in his career as a television executive. His goal was to demonstrate the relevance of Wooden's coaching style to the business world. The book also delves into his personal relationship with Wooden as his coach and mentor.\n\nIn 2004, a 93-year-old Wooden stated that he would not mind coming back as an assistant who could help players with practices and other light duties.\n\nDuring his tenure with the Bruins, Wooden became known as the \"Wizard of Westwood\", though he personally disdained the nickname. He gained lasting fame with UCLA by winning 620 games in 27 seasons and 10 NCAA titles during his last 12 seasons, including seven in a row from 1967 to 1973. His UCLA teams also established an NCAA men's basketball record winning streak of 88 games and four perfect 30–0 seasons. They also won 38 straight games in NCAA tournaments and 98 straight home wins at Pauley Pavilion.\n\n\"He never made more than $35,000 a year salary (not including camps and speaking engagements), including 1975, the year he won his 10th national championship, and never asked for a raise\", wrote Rick Reilly of ESPN. He was given a Bruin powder blue Mercedes that season as a retirement gift. According to his own writings, Wooden turned down an offer to coach the Los Angeles Lakers from owner Jack Kent Cooke that may have been ten times what UCLA was paying him.",

        "evidence": "Since sarcasm in text can be expected to induce cognitive load, it is reasonable to believe that it would require more processing time BIBREF14 . Hence, fixation duration normalized over total word count should usually be higher for a sarcastic text than for a non-sarcastic one. We observe this for all participants in our dataset, with the average fixation duration per word for sarcastic texts being at least 1.5 times more than that of non-sarcastic texts. To test the statistical significance, we conduct a two-tailed t-test (assuming unequal variance) to compare the average fixation duration per word for sarcastic and non-sarcastic texts. The hypothesized mean difference is set to 0 and the error tolerance limit ( INLINEFORM0 ) is set to 0.05. The t-test analysis, presented in Table TABREF11 , shows that for all participants, a statistically significant difference exists between the average fixation duration per word for sarcasm (higher average fixation duration) and non-sarcasm (lower average fixation duration). This affirms that the presence of sarcasm affects the duration of fixation on words.\nIt is important to note that longer fixations may also be caused by other linguistic subtleties (such as difficult words, ambiguity and syntactically complex structures) causing delay in comprehension, or occulomotor control problems forcing readers to spend time adjusting eye-muscles. So, an elevated average fixation duration per word may not sufficiently indicate the presence of sarcasm. But we would also like to share that, for our dataset, when we considered readability (Flesch readability ease-score BIBREF15 ), number of words in a sentence and average character per word along with the sarcasm label as the predictors of average fixation duration following a linear mixed effect model BIBREF16 , sarcasm label turned out to be the most significant predictor with a maximum slope. This indicates that average fixation duration per word has a strong connection with the text being sarcastic, at least in our dataset.\nWe now analyze scanpaths to gain more insights into the sarcasm comprehension process.\nIt is important to note that longer fixations may also be caused by other linguistic subtleties (such as difficult words, ambiguity and syntactically complex structures) causing delay in comprehension, or occulomotor control problems forcing readers to spend time adjusting eye-muscles.",

        "evidence": "Change is a universal property of language. For example, English has changed so much that Renaissance-era texts like The Canterbury Tales must now be read in translation. Even contemporary American English continues to change and diversify at a rapid pace—to such an extent that some geographical dialect differences pose serious challenges for comprehensibility BIBREF0 . Understanding language change is therefore crucial to understanding language itself, and has implications for the design of more robust natural language processing systems BIBREF1 .\nLanguage change is a fundamentally social phenomenon BIBREF2 . For a new linguistic form to succeed, at least two things must happen: first, speakers (and writers) must come into contact with the new form; second, they must decide to use it. The first condition implies that language change is related to the structure of social networks. If a significant number of speakers are isolated from a potential change, then they are unlikely to adopt it BIBREF3 . But mere exposure is not sufficient—we are all exposed to language varieties that are different from our own, yet we nonetheless do not adopt them in our own speech and writing. For example, in the United States, many African American speakers maintain a distinct dialect, despite being immersed in a linguistic environment that differs in many important respects BIBREF4 , BIBREF5 . Researchers have made a similar argument for socioeconomic language differences in Britain BIBREF6 . In at least some cases, these differences reflect questions of identity: because language is a key constituent in the social construction of group identity, individuals must make strategic choices when deciding whether to adopt new linguistic forms BIBREF7 , BIBREF8 , BIBREF9 . By analyzing patterns of language change, we can learn more about the latent structure of social organization: to whom people talk, and how they see themselves.\nBut, while the basic outline of the interaction between language change and social structure is understood, the fine details are still missing: What types of social network connections are most important for language change? To what extent do considerations of identity affect linguistic differences, particularly in an online context? Traditional sociolinguistic approaches lack the data and the methods for asking such detailed questions about language variation and change.\nIn this paper, we show that large-scale social media data can shed new light on how language changes propagate through social networks. We use a data set of Twitter users that contains all public messages for several million accounts, augmented with social network and geolocation metadata. This data set makes it possible to track, and potentially explain, every usage of a linguistic variable as it spreads through social media.

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nRecent studies have exposed the vulnerability of ML models to adversarial attacks, small input perturbations which lead to misclassification by the model.",

        "evidence": "At this point, we are leaving the historical analysis behind to speculate on what the group might have discovered if they had had access to a computer. First of all, did the Croatian group have a concrete idea for tackling alignment? Not really. However, an approach can be read between the lines of primarily BIBREF16 and BIBREF17. In BIBREF17, Pranić addresses the Soviet model by Andreev, looking at it as if it was composed of two modules – an understanding module and a generation module. Following the footsteps of Andreev, their interaction should be over an idealized language. Laszlo BIBREF16 notes that such an idealized language should be encoded by keeping the entropy in mind. He literally calls for using entropy to eliminate redundancy while translating to an artificial language, and as Mulić notes BIBREF7, Andreev's idea (which should be followed) was to use an artificial language as an intermediary language, which has all the essential structures of all the languages one wishes to translate.\nThe step which was needed here was to eliminate the notion of structure alignment and just seek sentential alignment. This, in theory, can be done by using only entropy. A simple alignment could be made by using word entropies in both languages and aligning the words by decreasing entropy. This would work better for translating into a language with no articles. A better approach, which was not beyond the thinking of the group since it was already proposed by Matković in his dissertation from 1957 BIBREF20, would be to use word bigrams and align them. It is worth mentioning that, although the idea of machine translation in the 1950s in Croatia did not have a significant influence on development of the field, it shows that Croatian linguists had contemporary views and necessary competencies for its development. But, unfortunately, the development of machine translation in Croatia had been stopped because of the previously discussed circumstances. In 1964, Laszlo went to the USA, where he spent the next seven years, and after returning to Croatia, he was active as a university professor, but because of disagreement with the ruling political option regarding Croatian language issues, he published very rarely and was mainly focused on other linguistic issues in that period, but his work was a major influence on the later development of computational linguistics in Croatia.\nFirst of all, did the Croatian group have a concrete idea for tackling alignment?

In contrast to the logical approaches cited above, our starting point is different in that we begin with the following two questions: 1) what is the simplest logical system that one can come up with to solve empirical NLI problems (i.e., the system with minimal amounts of primitives and background knowledge)?; and 2) what is the lower-bound performance of such a model? Like other approaches to natural logic BIBREF15, BIBREF16, our model works by reasoning over surface forms (as opposed to translating to symbolic representations) using a small inventory of monotonicity facts about quantifiers, lexical items and token-level polarity BIBREF17; proofs in the calculus are hence fully interpretable and expressible in ordinary language. Unlike existing work on natural logic, however, our model avoids the need for having expensive alignment and search sub-procedures BIBREF18, BIBREF19, and relies on a much smaller set of background knowledge and primitive relations than MacCartneyManning.\nSince our logic operates over surface forms, it is straightforward to hybridize our models.

However, the output generated can be repetitive and generic leading to monotonous or uninteresting responses (e.g “I don't know”) regardless of the input BIBREF1. While application of attention BIBREF2, BIBREF3 and advanced decoding mechanisms like beam search and variation sampling BIBREF4 have shown improvements, it does not solve the underlying problem. In creative text generation, the objective is not strongly bound to the ground truth—instead the objective is to generate diverse, unique or original samples. We attempt to do this through a discriminator which can give feedback to the generative model through a cost function that encourages sampling of creative tokens. The contributions of this paper are in the usage of a GAN framework to generate creative pieces of writing. Our experiments suggest that generative text models, while very good at encapsulating semantic, syntactic and domain information, perform better with external feedback from a discriminator for fine-tuning objectiveless decoding tasks like that of creative text. We show this by evaluating our model on three very different creative datasets containing poetry, metaphors and lyrics.\nPrevious work on handling the shortcomings of MLE include length-normalizing sentence probability BIBREF5, future cost estimation BIBREF6, diversity-boosting objective function BIBREF7, BIBREF1 or penalizing repeating tokens BIBREF8. When it comes to poetry generation using generative text models, Zhang and Lapata BIBREF9, Yi et al. BIBREF10 and Wang et al. BIBREF11 use language modeling to generate Chinese poems. However, none of these methods provide feedback on the quality of the generated sample and hence, do not address the qualitative objective required for creative decoding. For the task of text generation, MaskGAN BIBREF12 uses a Reinforcement Learning signal from the discriminator, FMD-GAN BIBREF13 uses an optimal transport mechanism as an objective function. GumbelGAN BIBREF14 uses Gumbel-Softmax distribution that replaces the non-differentiable sample from a categorical distribution with a differentiable sample to propagate stronger gradients. Li et al.

        "question": "What kind of method is TF-IDF?",
        "answer": "A method of converting text into numbers so that it can be represented meaningfully by a vector.",
        "evidence": "A valuable source of information in matching user accounts, one used in traditional stylometry tasks, is the way in which people use language. A speaker or writer's choice of words depends on many factors, including the rules of grammar, message content and stylistic considerations. There is a great variety of possible ways to compare the language patterns of two people. However, first we need a method for modelling the language of a given user. Below we explain how this is done.\nMost statistical language models do not attempt to explicitly model the complete language generation process, but rather seek a compact model that adequately explains the observed linguistic data. Probabilistic models of language assign probabilities to word sequences $w_1$ . . . $w_\\ell $ , and as such the likelihood of a corpus can be used to fit model parameters as well as characterize model performance.\nN-gram language modelling BIBREF18 , BIBREF19 , BIBREF20 is an effective technique that treats words as samples drawn from a distribution conditioned on other words, usually the immediately preceding $n-1$ words, in order to capture strong local word dependencies. The probability of a sequence of $\\ell $ words, written compactly as $w_1^\\ell $ is $\\Pr (w_1^\\ell )$ and can be factored exactly as $\\Pr (w_1^\\ell ) = \\Pr (w_1) \\prod _{i=2}^\\ell \\Pr (w_i|w_1^{i-1})$ \nHowever, parameter estimation in this full model is intractable, as the number of possible word combinations grows exponentially with sequence length. N-gram models address this with the approximation $\\tilde{\\Pr }(w_i|w_{i-n+1}^{i-1}) \\approx \\Pr (w_i|w_1^{i-1})$ using only the preceding $n-1$ words for context. A bigram model ( $n=2$ ) uses the preceding word for context, while a unigram model ( $n=1$ ) does not use any context.\nFor this work, we used unigram models in Python, utilizing some components from NLTK BIBREF21 . Probability distributions were calculated using Witten-Bell smoothing BIBREF19 . Rather than assigning word $w_i$ the maximum likelihood probability estimate $p_i = \\frac{c_i}{N}$ , where $c_i$ is the number of observations of word $w_i$ and $N$ is the total number of observed tokens, Witten-Bell smoothing discounts the probability of observed words to $p_i^* = \\frac{c_i}{N+T}$ where $T$ is the total number of observed word types. The remaining $Z$ words in the vocabulary that are unobserved (i.e. where $c_i = 0$ ) are given by $p_i^* = \\frac{T}{Z(N+T)}$ .\nWe experimented with two methods for measuring the similarity between n-gram language models. In particular, we tried approaches based on KL-divergence and perplexity BIBREF22 . We also tried two methods that do not rely on n-gram models, cosine similarity of TF-IDF vectors BIBREF23 , as well as our own novel method, called the confusion model.\nThe performance of each method is shown in Table 2 . Note that all methods outperform the random baseline in both accuracy and average rank by a great margin. Below we explain each of these metrics.\nThe first metric used for measuring the distance between the language of two user accounts is the Kullback-Leibler (KL) divergence BIBREF22 between the unigram probability distribution of the corpus corresponding to the two accounts. The KL-divergence provides an asymmetric measure of dissimilarity between two probability distribution functions $p$ and $q$ and is given by: $KL(p||q) = \\int p(x)ln\\frac{p(x)}{q(x)}$ \nWe can modify the equation to prove a symmetric distance between distributions: $KL_{2}(p||q) = KL(p||q)+KL(q||p)$ \nFor this method, the similarity metric is the perplexity BIBREF22 of the unigram language model generated from one account, $p$ and evaluated on another account, $q$ . Perplexity is given as: $PP(p,q) = 2^{H(p,q)}$ \nwhere $H(p,q)$ is the cross-entropy BIBREF22 between distributions of the two accounts $p$ and $q$ . More similar models lead to smaller perplexity. As with KL-divergence, we can make perplexity symmetric: $PP_{2}(p,q) = PP(p,q)+PP(q,p)$ \nThis method outperformed the KL-divergence method in terms of average rank but not accuracy (see Table 2 ).\nPerhaps the relatively low accuracies of perplexity and KL-divergence measures should not be too surprising. These measures are most sensitive to the variations in frequencies of most common words. For instance, in its most straightforward implementation, the KL-divergence measure would be highly sensitive to the frequency of the word “the\". Although this problem might be mitigated by the removal of stop words and applying topic modelling to the texts, we believe that this issue is more nuanced than that.\nDifferent social media (such as Twitter and Facebook) are used by people for different purposes, and thus Twitter and Facebook entries by the same person are likely to be thematically different. So it is likely that straightforward comparison of language models would be inefficient for this task.\nOne possible solution for this problem is to look at users' language models not in isolation, but in comparison to the languages models of everyone else. In other words, identify features of a particular language model that are characteristic to its corresponding user, and then use these features to estimate similarity between different accounts. This is a task that Term Frequency-Inverse Document Frequency, or TF-IDF, combined with cosine similarity, can manage.\nTF-IDF is a method of converting text into numbers so that it can be represented meaningfully by a vector BIBREF23 . TF-IDF is the product of two statistics, TF or Term Frequency and IDF or Inverse Document Frequency. Term Frequency measures the number of times a term (word) occurs in a document. Since each document will be of different size, we need to normalize the document based on its size. We do this by dividing the Term Frequency by the total number of terms.\nTF considers all terms as equally important, however, certain terms that occur too frequently should have little effect (for example, the term “the\"). And conversely, terms that occur less in a document can be more relevant. Therefore, in order to weigh down the effects of the terms that occur too frequently and weigh up the effects of less frequently occurring terms, an Inverse Document Frequency factor is incorporated which diminishes the weight of terms that occur very frequently in the document set and increases the weight of terms that occur rarely. Generally speaking, the Inverse Document Frequency is a measure of how much information a word provides, that is, whether the term is common or rare across all documents.\nUsing TF-IDF, we derive a vector from the corpus of each account. We measure the similarity between two accounts using cosine similarity: $Similarity(d1,d2) = \\frac{d1 \\cdot d2}{||d1||\\times ||d2||}$ \nHere, $d1 \\cdot d2$ is the dot product of two documents, and $||d1||\\times ||d2||$ is the product of the magnitude of the two documents. Using TD-IDF and cosine similarity, we achieved significantly better results than the last two methods, with an accuracy of $0.21$ and average rank of 999.\nTF-IDF can be thought of as a heuristic measure of the extent to which different words are characteristic of a user. We came up with a new, theoretically motivated measure of “being characteristic\" for words. We considered the following setup :\nThe whole corpus of the $11,224$ Twitter and Facebook accounts was treated as one long string;\nFor each token in the string, we know the user who produced it. Imagine that we removed this information and are now making a guess as to who the user was. This will give us a probability distribution over all users;\nNow imagine that we are making a number of the following samples: randomly selecting a word from the string, taking the true user, $TU$ for this word and a guessed user, $GU$ from correspondent probability distribution. Intuitively, the more often a particular pair, $TU=U_{1}, GU=U_{2}$ appear together, the stronger is the similarity between $U_{1}$ and $U_{2}$ ;\nWe then use mutual information to measure the strength of association. In this case, it will be the mutual information BIBREF22 between random variables, $TU=U_{1}$ and $GU=U_{2}$ . This mutual information turns out to be proportional to the probabilities of $U_{1}$ and $U_{2}$ in the dataset, which is undesirable for a similarity measure. To correct for this, we divide it by the probabilities of $U_{1}$ and $U_{2}$ ;\nWe call this model the confusion model, as it evaluated the probability that $U_{1}$ will be confused for $U_{2}$ on the basis of a single word. The expression for the similarity value according to the model is $S\\times log(S)$ , where $S$ is: $S=\\sum _{w} p(w)p(U_{1}|w)p(U_{2}|w)$ \nNote that if $U_{1}=U_{2}$ , the words contributing most to the sum will be ordered by their “degree of being characteristic\". The values, $p(w)$ and $p(u|w)$ have to be estimated from the corpus. To do that, we assumed that the corpus was produced using the following auxiliary model:\nFor each token, a user is selected from a set of users by multinomial distribution;\nA word is selected from a multinomial distribution of words for this user to produce the token.\nWe used Dirichlet distributions BIBREF24 as priors over multinomials. This method outperforms all other methods with an accuracy of $0.27$ and average rank of 859.\nTF-IDF is a method of converting text into numbers so that it can be represented meaningfully by a vector [17].",

By extension, this also involves things that are outside of physical appearance, such as focusing on great qualities she has that have nothing to do with physical fitness nor appearance: this can help with self-esteem.

In this paper, we investigate how appropriate such data is for modeling natural dialog, and introduce Interview, a new high-quality large-scale open-domain conversational dataset grounded in interview settings with annotations for specific speaker roles.\nWe compare the performance of state-of-the-art language models fine-tuned on Interview and other popular conversational datasets, demonstrating that Interview contains more complex dialog and better models the characteristics of natural spoken conversations. Our dataset is an order of magnitude larger than existing high-quality natural dialog datasets and contains speaker role annotations for each turn, facilitating the development of conversational agents and assistive systems for settings involving specific speaker roles, such as doctor-patient interviews or hosted talk shows.\nIn particular, we explore the tasks of role modeling in media dialog and role change detection on Interview and find that leveraging role information can enable more nuanced, on-topic and natural dialog generation, as well as improve role change classification performance.\nIn summary, we present Interview, the first large-scale open-domain media dialog dataset. We explore two tasks for which it serves as a promising benchmark dataset: speaker role modeling and speaker change detection.

These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 .

        "evidence": "Knowledge sharing platforms such as Quora and Zhihu emerge as very convenient tools for acquiring knowledge. These question and answer (Q&A) platforms are newly emerged communities about knowledge acquisition, experience sharing and social networks services (SNS).\nUnlike many other Q&A platforms, Zhihu platform resembles a social network community. Users can follow other people, post ideas, up-vote or down-vote answers, and write their own answers. Zhihu allows users to keep track of specific fields by following related topics, such as “Education”, “Movie”, “Technology” and “Music”. Once a Zhihu user starts to follow a specific topic or a person, the related updates are automatically pushed to the user's feed timeline.\nAlthough these platforms have exploded in popularity, they face some potential problems. The key problem is that as the number of users grows, a large volume of low-quality questions and answers emerge and overwhelm users, which make users hard to find relevant and helpful information.\nZhihu Live is a real-time voice-answering product on the Zhihu platform, which enables the speakers to share knowledge, experience, and opinions on a subject. The audience can ask questions and get answers from the speakers as well. It allows communication with the speakers easily and efficiently through the Internet. Zhihu Live provides an extremely useful reward mechanism (like up-votes, following growth and economic returns), to encourage high-quality content providers to generate high-level information on Zhihu platform.\nHowever, due to the lack of efficient filter mechanism and evaluation schemes, many users suffer from lots of low-quality contents, which affects the service negatively. Recently, studies on social Q&A platforms and knowledge sharing are rising and have achieved many promising results. Shah et al. BIBREF0 propose a data-driven approach with logistic regression and carefully designed hand-crafted features to predict the answer quality on Yahoo! Answers. Wang et al. BIBREF1 illustrate that heterogeneity in the user and question graphs are important contributors to the quality of Quora's knowledge base. Paul et al. BIBREF2 explore reputation mechanism in quora through detailed data analysis, their experiments indicate that social voting helps users identify and promote good content but is prone to preferential attachment. Patil et al. BIBREF3 propose a method to detect experts on Quora by their activity, quality of answers, linguistic characteristics and temporal behaviors, and achieves 97% accuracy and 0.987 AUC. Rughinis et al. BIBREF4 indicate that there are different regimes of engagement at the intersection of the technological infrastructure and users' participation in Quora.\nAll of these works are mainly focused on answer ranking and answer quality evaluation. But there is little research achievement about quality evaluation in voice-answering areas. In this work, we present a data-driven approach for quality evaluation about Zhihu Live, by consuming the dataset we collected to gather knowledge and insightful conclusion. The proposed data-driven approach includes data collection, storage, preprocessing, data analysis, and predictive analysis via machine learning. The architecture of our data-driven method is shown in Fig. FIGREF3 . The records are crawled from Zhihu Live official website and stored in MongoDB. Data preprocessing methods include cleaning and data normalization to make the dataset satisfy our target problem. Descriptive data analysis and predictive analysis are also conducted for deeper analysis about this dataset.\nThe main contributions of this paper are as follows: (1) We release a public benchmark dataset which contains 7242 records and 286,938 text comments about Zhihu Live. Detailed analysis about the dataset is also discussed in this paper. This dataset could help researchers verify their ideas in related fields. (2) By analyzing this dataset, we gain several insightful conclusion about Zhihu Live. (3) We also propose a multi-branched neural network (MTNet) to evaluate Zhihu Lives' scores. The superiority of our proposed model is demonstrated by comparing performance with other mainstream regressors.\nThe rest of this paper is organized as follows: Section 2 describes detailed procedures of ZhihuLive-DB collection, and descriptive analysis. Section 3 illustrates our proposed MTNet. In section 4, we give a detailed description of experiments, and the last section discusses the conclusion of this paper and future work.\nIn this work, we present a data-driven approach for quality evaluation about Zhihu Live, by consuming the dataset we collected to gather knowledge and insightful conclusion.",

        "answer": "Cyberbullying is considered as a complex phenomenon consisiting of different forms.",
        "evidence": "As mentioned earlier, although research on cyberbullying detection is more limited than social studies on the phenomenon, some important advances have been made in recent years. In what follows, we present a brief overview of the most important natural language processing approaches to cyberbullying detection.\nAlthough some studies have investigated the effectiveness of rule-based modelling BIBREF31 , the dominant approach to cyberbullying detection involves machine learning. Most machine learning approaches are based on supervised BIBREF32 , BIBREF33 , BIBREF34 or semi-supervised learning BIBREF35 . The former involves the construction of a classifier based on labeled training data, whereas semi-supervised approaches rely on classifiers that are built from a training corpus containing a small set of labeled and a large set of unlabelled instances (a method that is often used to handle data sparsity). As cyberbullying detection essentially involves the distinction between bullying and non-bullying posts, the problem is generally approached as a binary classification task where the positive class is represented by instances containing (textual) cyberbullying, while the negative class includes instances containing non-cyberbullying or `innocent' text.\nA key challenge in cyberbullying research is the availability of suitable data, which is necessary to develop models that characterise cyberbullying. In recent years, only a few datasets have become publicly available for this particular task, such as the training sets provided in the context of the CAW 2.0 workshop and more recently, the Twitter Bullying Traces dataset BIBREF36 . As a result, several studies have worked with the former or have constructed their own corpus from social media websites that are prone to bullying content, such as YouTube BIBREF32 , BIBREF33 , Formspring BIBREF33 , and ASKfm BIBREF37 (the latter two are social networking sites where users can send each other questions or respond to them). Despite the bottleneck of data availability, existing approaches to cyberbullying detection have shown its potential, and the relevance of automatic text analysis techniques to ensure child safety online has been recognised BIBREF38 , BIBREF39 .\nAmong the first studies on cyberbullying detection are BIBREF34 , BIBREF31 , BIBREF33 , who explored the predictive power of INLINEFORM0 -grams (with and without tf-idf weighting), part-of-speech information (e.g. first and second pronouns), and sentiment information based on profanity lexicons for this task. Similar features were also exploited for the detection of cyberbullying events and fine-grained text categories related to cyberbullying BIBREF37 , BIBREF40 . More recent studies have demonstrated the added value of combining such content-based features with user-based information, such as including users' activities on a social network (i.e., the number of posts), their age, gender, location, number of friends and followers, and so on BIBREF32 , BIBREF35 , BIBREF41 . Moreover, semantic features have been explored to further improve classification performance of the task. To this end, topic model information BIBREF42 , as well as semantic relations between INLINEFORM1 -grams (according to a Word2Vec model BIBREF43 ) have been integrated.\nAs mentioned earlier, data collection remains a bottleneck in cyberbullying research. Although cyberbullying has been recognised as a serious problem (cf. Section SECREF1 ), real-world examples are often hard to find in public platforms. Naturally, the vast majority of communications do not contain traces of verbal aggression or transgressive behaviour. When constructing a corpus for machine learning purposes, this results in imbalanced datasets, meaning that one class (e.g. cyberbullying posts) is much less represented in the corpus than the other (e.g. non-cyberbullying posts). To tackle this problem, several studies have adopted resampling techniques BIBREF35 , BIBREF41 , BIBREF31 that create synthetic minority class examples or reduce the number of negative class examples (i.e., minority class oversampling and majority class undersampling BIBREF44 ).\nTable TABREF9 presents a number of recent studies on cyberbullying detection, providing insight into the state of the art in cyberbullying research and the contribution of the current research to the domain.\nThe studies discussed in this section have demonstrated the feasibility of automatic cyberbullying detection in social media data by making use of a varied set of features. Most of them have, however, focussed on cyberbullying `attacks', or posts written by a bully. Moreover, it is not entirely clear if different forms of cyberbullying have been taken into account (e.g. sexual intimidation or harassment, or psychological threats), in addition to derogatory language or insults.\nIn the research described in this paper, cyberbullying is considered a complex phenomenon consisting of different forms of harmful behaviour online, which are described in more detail in our annotation scheme BIBREF30 . Purposing to facilitate manual monitoring efforts on social networks, we develop a system that automatically detects signals of cyberbullying, including attacks from bullies, as well as victim and bystander reactions. Similarly, BIBREF42 investigated bullying traces posted by different author roles (accuser, bully, reporter, victim). However, they collected tweets by using specific keywords (i.e., bully, bullied and bullying). As a result, their corpus contains many reports or testimonials of a cyberbullying incident (example 1), instead of actual signals that cyberbullying is going on. Moreover, their method implies that cyberbullying-related content devoid of such keywords will not be part of the training corpus.\n`Some tweens got violent on the n train, the one boy got off after blows 2 the chest... Saw him cryin as he walkd away :( bullying not cool' BIBREF42 \nFor this research, English and Dutch social media data were annotated for different forms of cyberbullying, based on the actors involved in a cyberbullying incident. After preliminary experiments for Dutch BIBREF37 , BIBREF40 , we currently explore the viability of detecting cyberbullying-related posts in Dutch and English social media. To this end, binary classification experiments are performed exploiting a rich feature set and optimised hyperparameters.\nfont=footnotesize,sc,justification=centering,labelsep=period\nIn the research described in this paper, cyberbullying is considered a complex phenomenon consisting of different forms of harmful behaviour online, which are described in more detail in our annotation scheme (Van Hee, Verhoeven, et al., 2015).",

        "evidence": "Modeling temporal and sequential data, which is crucial in machine learning, can be applied in many areas, such as speech and natural language processing. Deep neural networks (DNNs) have garnered interest from many researchers after being successfully applied in image classification BIBREF0 and speech recognition BIBREF1 . Another type of neural network, called a recurrent neural network (RNN) is also widely used for speech recognition BIBREF2 , machine translation BIBREF3 , BIBREF4 and language modeling BIBREF5 , BIBREF6 . RNNs have achieved many state-of-the-art results. Compared to DNNs, they have extra parameters for modeling the relationships of previous or future hidden states with current input where the RNN parameters are shared for each input time-step.\nGenerally, RNNs can be separated by a simple RNN without gating units, such as the Elman RNN BIBREF7 , the Jordan RNN BIBREF8 , and such advanced RNNs with gating units as the Long-Short Term Memory (LSTM) RNN BIBREF9 and the Gated Recurrent Unit (GRU) RNN BIBREF4 . A simple RNN usually adequate to model some dataset and a task with short-term dependencies like slot filling for spoken language understanding BIBREF10 . However, for more difficult tasks like language modeling and machine translation where most predictions need longer information and a historical context from each sentence, gating units are needed to achieve good performance. With gating units for blocking and passing information from previous or future hidden layer, we can learn long-term information and recursively backpropagate the error from our prediction without suffering from vanishing or exploding gradient problems BIBREF9 . In spite of this situation, the concept of gating mechanism does not provide an RNN with a more powerful way to model the relation between the current input and previous hidden layer representations.\nMost interactions inside RNNs between current input and previous (or future) hidden states are represented using linear projection and addition and are transformed by the nonlinear activation function. The transition is shallow because no intermediate hidden layers exist for projecting the hidden states BIBREF11 . To get a more powerful representation on the hidden layer, Pascanu et al. BIBREF11 modified RNNs with an additional nonlinear layer from input to the hidden layer transition, hidden to hidden layer transition and also hidden to output layer transition. Socher et al. BIBREF12 , BIBREF13 proposed another approach using a tensor product for calculating output vectors given two input vectors. They modified a Recursive Neural Network (RecNN) to overcome those limitations using more direct interaction between two input layers. This architecture is called a Recursive Neural Tensor Network (RecNTN), which uses a tensor product between child input vectors to represent the parent vector representation. By adding the tensor product operation to calculate their parent vector, RecNTN significantly improves the performance of sentiment analysis and reasoning on entity relations tasks compared to standard RecNN architecture. However, those models struggle to learn long-term dependencies because the do not utilize the concept of gating mechanism.\nIn this paper, we proposed a new RNN architecture that combine the gating mechanism and tensor product concepts to incorporate both advantages in a single architecture. Using the concept of such gating mechanisms as LSTMRNN and GRURNN, our proposed architecture can learn temporal and sequential data with longer dependencies between each input time-step than simple RNNs without gating units and combine the gating units with tensor products to represent the hidden layer with more powerful operation and direct interaction. Hidden states are generated by the interaction between current input and previous (or future) hidden states using a tensor product and a non-linear activation function allows more expressive model representation. We describe two different models based on LSTMRNN and GRURNN. LSTMRNTN is our proposed model for the combination between a LSTM unit with a tensor product inside its cell equation and GRURNTN is our name for a GRU unit with a tensor product inside its candidate hidden layer equation.\nIn Section \"Background\" , we provide some background information related to our research. In Section \"Proposed Architecture\" , we describe our proposed RNN architecture in detail. We evaluate our proposed RNN architecture on word-level and character-level language modeling tasks and reported the result in Section \"Experiment Settings\" . We present related works in Section \"Related Work\" .

At present, automated journalism typically focuses on domains such as sports, finance and similar statistics-based reporting, where there is a commercial product potential due to the high volume of news, combined with the expectation of a relatively straightforward task.\nNews generation systems—especially those deployed in practice—tend to be based on intricate template filling, aiming to give the users the full control of the generated facts, while maintaining a reasonable variability of the resulting text. This comes at the price of having to develop the templates and specify their control logic, neither of which are tasks naturally fitting journalists' work. Further, this development needs to be repeated for every domain, as the templates are not easily transferred across domains. Examples of the template-based news generation systems for Finnish are Voitto by the Finnish Public Service Broadcasting Company (YLE) used for sports news generation, as well as Vaalibotti BIBREF0, a hybrid machine learning and template-based system used for election news.\nBIBREF1 suggested a neural template generation, which jointly models latent templates and text generation. Such a system increases interpretability and controllability of the generation, however, recent sequence-to-sequence systems represent the state-of-the-art in data-to-text generation. BIBREF2\nIn this paper, we report on the development of a news generation system for the Finnish ice hockey news domain, based on sequence-to-sequence methods. In order to train such a system, we compile a corpus of news based on over 2000 game reports from the Finnish News Agency STT. While developing this corpus into a form suitable for training of end-to-end systems naturally requires manual effort, we argue that compiling and refining a set of text examples is a more natural way for journalists to interact with the system, in order for them to codify their knowledge and to adapt it for new domains.\nOur aim is to generate reports that give an overview of a game based on information inferrable from the statistics. Such reports can be used either as a basis for further post-editing by a journalist imprinting own insights and background information, or even used directly as a news stream labelled as machine-generated.\nIn the following, we will introduce the news dataset and the process of its creation, introduce an end-to-end model for news generation, and evaluate its output respective to the abovementioned objectives.\nIn the following, we will introduce the news dataset and the process of its creation, introduce an end-to-end model for news generation, and evaluate its output respective to the abovementioned objectives.",

        "question": "All sorts of setting of affection classification by what correlation?",
        "answer": "First, one may use the same feature extraction and engineering approaches to represent the text spans. Second, one would expect that knowledge from one task can be transfered to the others and this would benefit the performance.",
        "evidence": "Automatic classification of sentiment has mainly focused on categorizing tweets in either two (binary sentiment analysis) or three (ternary sentiment analysis) categories BIBREF0 . In this work we study the problem of fine-grained sentiment classification where tweets are classified according to a five-point scale ranging from VeryNegative to VeryPositive. To illustrate this, Table TABREF3 presents examples of tweets associated with each of these categories. Five-point scales are widely adopted in review sites like Amazon and TripAdvisor, where a user's sentiment is ordered with respect to its intensity. From a sentiment analysis perspective, this defines a classification problem with five categories. In particular, Sebastiani et al. BIBREF1 defined such classification problems whose categories are explicitly ordered to be ordinal classification problems. To account for the ordering of the categories, learners are penalized according to how far from the true class their predictions are.\nAlthough considering different scales, the various settings of sentiment classification are related. First, one may use the same feature extraction and engineering approaches to represent the text spans such as word membership in lexicons, morpho-syntactic statistics like punctuation or elongated word counts BIBREF2 , BIBREF3 . Second, one would expect that knowledge from one task can be transfered to the others and this would benefit the performance. Knowing that a tweet is “Positive” in the ternary setting narrows the classification decision between the VeryPositive and Positive categories in the fine-grained setting. From a research perspective this raises the question of whether and how one may benefit when tackling such related tasks and how one can transfer knowledge from one task to another during the training phase.\nOur focus in this work is to exploit the relation between the sentiment classification settings and demonstrate the benefits stemming from combining them. To this end, we propose to formulate the different classification problems as a multitask learning problem and jointly learn them. Multitask learning BIBREF4 has shown great potential in various domains and its benefits have been empirically validated BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 using different types of data and learning approaches. An important benefit of multitask learning is that it provides an elegant way to access resources developed for similar tasks. By jointly learning correlated tasks, the amount of usable data increases. For instance, while for ternary classification one can label data using distant supervision with emoticons BIBREF9 , there is no straightforward way to do so for the fine-grained problem. However, the latter can benefit indirectly, if the ternary and fine-grained tasks are learned jointly.\nThe research question that the paper attempts to answer is the following: Can twitter sentiment classification problems, and fine-grained sentiment classification in particular, benefit from multitask learning? To answer the question, the paper brings the following two main contributions: (i) we show how jointly learning the ternary and fine-grained sentiment classification problems in a multitask setting improves the state-of-the-art performance, and (ii) we demonstrate that recurrent neural networks outperform models previously proposed without access to huge corpora while being flexible to incorporate different sources of data.\nFirst, one may use the same feature extraction and engineering approaches to represent the text spans such as word membership in lexicons, morpho-syntactic statistics like punctuation or elongated word counts (Balikas & Amini, 2016; Kiritchenko, Zhu, & Mohammad, 2014).

        "evidence": "Categories such as animal or furniture are fundamental cognitive building blocks allowing humans to efficiently represent and communicate the complex world around them. Concepts (e.g., dog, table) are grouped into categories based on shared properties pertaining, for example, to their behavior, appearance, or function. Categorization underlies other cognitive functions such as perception BIBREF0 , BIBREF1 or language BIBREF2 , BIBREF3 , and there is evidence that categories are not only shaped by the world they represent, but also by the language through which they are communicated BIBREF4 , BIBREF5 . Although mental categories exist across communities and cultures, their exact manifestations differ BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . For example, American English speakers prefer taxonomic categorizations (e.g., mouse,squirrel) while Chinese speakers tend to prefer to categorize objects relationally (e.g., tree, squirrel; BIBREF7 ).\nGiven their prevalent function in human cognition, the acquisition and representation of categories has attracted considerable attention in cognitive science, and numerous theories have emerged BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . Empirical studies of category acquisition and representation, have been predominantly based on small-scale laboratory experiments. In a typical experiment, human subjects are presented with small sets of often artificial concepts, such as binary strings BIBREF14 or colored shapes BIBREF15 , with strictly controlled features BIBREF16 , BIBREF17 , BIBREF18 . Hypotheses and principles of human categorization are established based on the processes and characteristics of the categorizations produced by the participants. The distribution of subjects participating in such studies is often skewed towards members of cultural and socioeconomic groups which are prevalent in the environment where the research is conducted, and typically consists to a large proportion of western, educated, wealthy and English-speaking participants often sampled from the even more specific population of college students. The demographic and socioeconomic bias has been long recognized, and the question of how this bias might impact conclusions about human cognition in general BIBREF19 and category learning specifically is under active debate BIBREF9 . Although laboratory studies are invaluable for understanding categorization phenomena in a controlled environment, they are also expensive and time-consuming to conduct, and consequently problematic to scale.\nIn this work, we scale the investigation of category learning and representation along two axes: (1) the complexity of the learning environment, and consequently the richness of learnable concept and category representations, and (2) the diversity of languages and cultures considered in evaluation. We present a novel knowledge-lean, cognitively motivated Bayesian model which learns categories and their structured features jointly from large natural language text corpora in five diverse languages: Arabic, Chinese, English, French, and German. We approximate the learning environment using large corpora of natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Besides text corpora can cover arbitrarily semantically complex domains, and are available across languages, providing an ideal test environment for studying categorization at scale.\nFigure 1 illustrates example input to our model, and Figure 2 shows example categories and associated features as induced by our model from the English Wikipedia. Following prior work BIBREF21 , BIBREF22 , we create language-specific sets of stimuli, each consisting of a mention of target concept (e.g., apple), within its local linguistic context (e.g., {contains, seeds}; cf., Figure 1 ). We consider each stimulus an observation of the concept, i.e., the word referring to the concept is an instance of the concept itself, and its context words are a representation of its features. Our model infers categories as groups of concepts occurring with similar features; and it infers feature types as groups of features which co-occur with each other. The output of our model (cf., Figure 2 ) are categories as clusters of concepts, each associated with a set of feature types, i.e., thematically coherent groups of features. We train a separate model on each of our target languages, each time presenting the model with input stimuli from the relevant language.\nComputational models in general, and Bayesian models in particular, allow to investigate hypotheses about cognitive phenomena by systematically modifying the learning mechanism or available input while observing the learning outcome. Bayesian models have been applied to a variety of cognitive phenomena BIBREF23 , BIBREF24 , BIBREF25 , and category acquisition is no exception. Following from Anderson's BIBREF14 , BIBREF26 , BIBREF27 seminal work, a number of models have been developed, and tested in their ability to reproduce human behavior in laboratory settings by exposing the models to small sets of controlled inputs with restricted features. In this work we draw on the full potential of computational modeling by exposing our models to (a) more complex data reflecting the diversity of contexts in which concepts can be observed; and (b) a input data in different languages, shedding light on the applicability of computational cognitive models beyond the prevalent English test language.\nCategorization tasks in a laboratory environment typically involve stimuli with a small set of features which are relevant to the categorization target, eliminating the need to detect features, and discriminate them in their relevance. In the real world, however, concepts are observed in contexts and a substantial part of acquiring categorical knowledge involves learning which features are useful to discriminate among concepts. In fact, research has shown that humans learn features jointly with categories BIBREF28 , BIBREF29 and that these features are themselves structured so as to represent the diversity and complexity of the properties exhibited in the world BIBREF30 , BIBREF31 , BIBREF32 . Our novel model of category learning presented in this article, jointly learns categories and their structured features from large sets of informationally rich data.\nOur work exemplifies the opportunities that arise from computational models and large data sets for investigating the mechanisms with which conceptual representations emerge, as well as the representations themselves in a broader context. We simulate the acquisition of categories comprising hundreds of concepts by approximating the learning environment with natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , as well as human-like biases BIBREF33 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Text corpora are a prime example of naturally occurring large-scale data sets BIBREF34 , BIBREF35 , BIBREF36 . In analogy to real-world situations, they encapsulate rich, diverse, and potentially noisy, information. The wide availability of corpora allows us to train and evaluate cognitive models on data from diverse languages and cultures. We test our model on corpora from five languages, derived from the online encyclopedia Wikipedia in Arabic, Chinese, French, English, and German. Wikipedia is a valuable resource for our study because it (a) discusses concepts and their properties explicitly and can thus serve as a proxy for the environment speakers of a language are exposed to; and (b) allows us to construct corpora which are highly comparable in their content across languages, controlling for effects of genre or style.\nWe present a series of evaluations investigating the quality of the induced categories and features. Leveraging a reference comprising hundreds of concepts and more than 30 categories, we demonstrate that our model learns meaningful categories in all five target languages. We furthermore show, through crowd-sourced evaluations involving native speakers of each target language, that the induced feature types are (a) each thematically coherent and interpretable; and (b) are associated with categories in comprehensible ways. We discuss language-specific idiosyncrasies emerging from the induced representations.\nIn the remainder of this article, we first review related literature, before we present a cognitively motivated model for learning categories and their structured representations from large natural language corpora. We then evaluate the quality of the emerging representations, as well as the generalizability of our model across languages. Note that the primary goal of this work is not to characterize differences in categories and features arising from different languages (even though this would be an interesting avenue for future work). Rather, we aim to demonstrate the utility of large-scale naturalistic datasets for cognitive modeling, and to verify mechanisms of categorization known from laboratory studies at scale and across communities.\nOur experiments indicate that the proposed method outperforms neural language models trained with well-tuned hyperparameters and achieves state-of-the-art scores on each dataset.",

More specifically, at each iteration after obtaining a keyword-specific expectation from the crowd, the authors train the model using expectation regularization and select those keyword-related microposts for which the model's prediction disagrees the most with the crowd's expectation.",
        "evidence": "Event detection on microblogging platforms such as Twitter aims to detect events preemptively. A main task in event detection is detecting events of predetermined types BIBREF0, such as concerts or controversial events based on microposts matching specific event descriptions. This task has extensive applications ranging from cyber security BIBREF1, BIBREF2 to political elections BIBREF3 or public health BIBREF4, BIBREF5. Due to the high ambiguity and inconsistency of the terms used in microposts, event detection is generally performed though statistical machine learning models, which require a labeled dataset for model training. Data labeling is, however, a long, laborious, and usually costly process. For the case of micropost classification, though positive labels can be collected (e.g., using specific hashtags, or event-related date-time information), there is no straightforward way to generate negative labels useful for model training. To tackle this lack of negative labels and the significant manual efforts in data labeling, BIBREF1 (BIBREF1, BIBREF3) introduced a weak supervision based learning approach, which uses only positively labeled data, accompanied by unlabeled examples by filtering microposts that contain a certain keyword indicative of the event type under consideration (e.g., `hack' for cyber security). Another key technique in this context is expectation regularization BIBREF6, BIBREF7, BIBREF1. Here, the estimated proportion of relevant microposts in an unlabeled dataset containing a keyword is given as a keyword-specific expectation. This expectation is used in the regularization term of the model's objective function to constrain the posterior distribution of the model predictions. By doing so, the model is trained with an expectation on its prediction for microposts that contain the keyword. Such a method, however, suffers from two key problems:\nDue to the unpredictability of event occurrences and the constantly changing dynamics of users' posting frequency BIBREF8, estimating the expectation associated with a keyword is a challenging task, even for domain experts;\nThe performance of the event detection model is constrained by the informativeness of the keyword used for model training. As of now, we lack a principled method for discovering new keywords and improve the model performance.\nTo address the above issues, we advocate a human-AI loop approach for discovering informative keywords and estimating their expectations reliably. Our approach iteratively leverages 1) crowd workers for estimating keyword-specific expectations, and 2) the disagreement between the model and the crowd for discovering new informative keywords. More specifically, at each iteration after we obtain a keyword-specific expectation from the crowd, we train the model using expectation regularization and select those keyword-related microposts for which the model's prediction disagrees the most with the crowd's expectation; such microposts are then presented to the crowd to identify new keywords that best explain the disagreement. By doing so, our approach identifies new keywords which convey more relevant information with respect to existing ones, thus effectively boosting model performance. By exploiting the disagreement between the model and the crowd, our approach can make efficient use of the crowd, which is of critical importance in a human-in-the-loop context BIBREF9, BIBREF10. An additional advantage of our approach is that by obtaining new keywords that improve model performance over time, we are able to gain insight into how the model learns for specific event detection tasks. Such an advantage is particularly useful for event detection using complex models, e.g., deep neural networks, which are intrinsically hard to understand BIBREF11, BIBREF12. An additional challenge in involving crowd workers is that their contributions are not fully reliable BIBREF13. In the crowdsourcing literature, this problem is usually tackled with probabilistic latent variable models BIBREF14, BIBREF15, BIBREF16, which are used to perform truth inference by aggregating a redundant set of crowd contributions. Our human-AI loop approach improves the inference of keyword expectation by aggregating contributions not only from the crowd but also from the model. This, however, comes with its own challenge as the model's predictions are further dependent on the results of expectation inference, which is used for model training. To address this problem, we introduce a unified probabilistic model that seamlessly integrates expectation inference and model training, thereby allowing the former to benefit from the latter while resolving the inter-dependency between the two.\nTo the best of our knowledge, we are the first to propose a human-AI loop approach that iteratively improves machine learning models for event detection. In summary, our work makes the following key contributions:\nA novel human-AI loop approach for micropost event detection that jointly discovers informative keywords and estimates their expectation;\nA unified probabilistic model that infers keyword expectation and simultaneously performs model training;\nAn extensive empirical evaluation of our approach on multiple real-world datasets demonstrating that our approach significantly improves the state of the art by an average of 24.3% AUC.\nThe rest of this paper is organized as follows. First, we present our human-AI loop approach in Section SECREF2. Subsequently, we introduce our proposed probabilistic model in Section SECREF3. The experimental setup and results are presented in Section SECREF4. Finally, we briefly cover related work in Section SECREF5 before concluding our work in Section SECREF6.\nOur approach iteratively leverages 1) crowd workers for estimating keyword-specific expectations, and 2) the disagreement between the model and the crowd for discovering new informative keywords.

        "question": "What exactly is “Standard Training” in Section 5?",
        "answer": "For standard approach, the only difference is not using an additional diversity loss. The remaining regularizers, e.g., data augmentation, weight decay etc, are all applied as specified per-experiment. we clarified this in the updated manuscript.",
        "evidence": "We start by evaluating our proposed diversity approach on two image datasets: CIFAR10 and CI-FAR100. We use our approach on three state-of-the-art CNNs: ResNext-29-08-16: we consider the standard ResNext Model with a 29-layer architecture, a cardinality of 8, and a width of 16. DenseNet-12: we use DenseNet with the 40layer architecture and a growth rate of 12. ResNet50: we consider the standard ResNet model with 50 layers. We compare against the standard networks 2 as well as networks trained with DeCov diversity strategy. For each approach the hyperparameters are selected based on the validation set. The full experimental setup is presented in the Appendix. We report the average performance over three random seeds. We note that, compared to the standard approach, employing a diversity strategy generally boosts the results for all the three models and that our approach consistency outperforms both competing For the hyperparameters, we use λ = 0.001 and γ = 10. The full experimental setup is presented in the Appendix. Table reports the test errors of the different diversity strategies. To study the effect of diversity on the generalization gap, we also report the final training errors and the generalization gap, i.e., training accuracy -test accuracy. As it can be seen, diversity (our approach and DeCov) reduces the test error of the model and yields a better performance. We note that, in accordance with our theoretical findings in Section 2, using diversity indeed reduces overfitting and decreases the empirical generalisation gap of neural networks. In fact, our logdet variant reduces the empirical generalization gap of the model by 1.8% compared to the standard approach. We note that our approach has a small additional time cost. For example for ResNet50, our direct, det and logdet variants take only 0.29%, 0.39%, and 0.49% extra training time, respectively.\nFigure: Sensitivity analysis of λ and γ on both the model accuracy and its generalization ability using ResNet50 trained on ImageNet.\nSensitivity analysis: To further investigate the effect of the proposed diversity strategy, we conduct a sensitivity analysis using ImageNet on the hyperparameters of our methods: γ, which is the RBF parameter used to measure the pairwise similarity between two units, and λ, which controls the contribution of the global diversity term to the global loss. We analyse the effect of the two parameters on both the final performance of the models and its generalization ability. The analysis is presented in Figure and in supplementary material. As it can be seen, promoting the within-layer diversity consistently reduces overfitting and decreases the generalization gap for most of the hyperparameters values. Moreover, we note that global modeling of diversity, i.e., det and logdet variants, yield tighter generalization gaps compared to the non-global direct approach. It is worth noting that Figure shows that there is a trade-off between the generalization gap and the final error. Emphasizing diversity and using a high weight for the diversity term significantly decreases the generalization gap, but this damages the performance of the model compared to the standard approach. For lower values of λ, the model is able to significantly outperform the standard approach on both the test error and the generalization gap.\nConnection to Theory: In Section 2, we provided theoretical bounds for the generalization errors of neural networks, which are inversely proportional to the diversity term, d min , the lower bound of\nTo show that the proposed regularizer indeed improves diversity, we track the empirical average of the aforementioned variable, i.e.,\n2 during the training. The results for both the standard approach and the logdet variant of our approach are reported in Figure. As it can be seen, our regularizer yields in higher diversity which reduces overfitting and leads to better generalization. Compatibility with Dropout: Dropout) is a popular regularization technique that, similarly to our approach, is applied on top of the layer output and has been known to improve generalization and reduce overfitting. Here, we evaluate the compatibility of our approach with Dropout. We add a Dropout regularizer with 20% rate on top the last intermediate representation layer of both ResNet50 and Wide-ResNet50. The results are reported in Table. We note that adding a diversity regularizer alongside the Dropout consistently yields lower error rates compared to only Dropout except for the det variant on Wide-ResNet50. For Wide-ResNet50, the combination of our logdet variant and Dropout leads to 0.53%, 0.25%, and 0.38% improvement compared to standard approach, Dropout only, and our logdet variant only, respectively.\nBeyond CNN models, we also evaluate the performance of our diversity strategy on modern attention-free, multi-layer perceptron (MLP) based models for image classification. Such models are known to exhibit high overfitting and require regularization. We evaluate how diversity affects the accuracy of such models on CIFAR10. In particular, we conduct a simple experiment using two models: MLP-Mixer, gMLP with four blocks each. The full description of the experimental setup is presented in the Appendix. The results in Table show that employing a diversity strategy can indeed improve the performance of these models thanks to its ability to learn rich and robust representation of the input.\nTransfer learning: Beyond standard classification, the proposed approach can be useful, e.g., in transfer learning, where the main goal is to 'transfer' previously learned representation to solve new tasks. Thus, learning a rich and diverse representation is beneficial and can lead to better transferability. To demonstrate this, we conduct another experiment, where we use ImageNet-pretrained ResNet50 models with the different diversity approaches and we finetune them to CIFAR10 and CIFAR100. The results are reported in Table. As it can be seen, employing a diversity strategy helps in the transfer learning context and leads consistently to lower error rates. For example, the log variant of our approach leads to 0.94% and 1.27% gains on CIFAR10 and CIFAR100, respectively. To further demonstrate the usefulness of promoting diversity, we test the robustness of our approach in the presence of label noise. In such situations, standard neural network tend to overfit to the noisy sample and not generalize well to the test set. Enforcing diversity can lead to better and richer representation attenuating the effect of noise. To show this, we performed additional experiments with label noise (20% and 40%) on CIFAR10 and CIFAR100 using ResNet50. The results are reported in Table. As it can be seen, in the presence of noise, the gap between the standard approach and diversity (Decov and ours) increases. For example, our logdet variant boosts the results by 1.71% and 3.59% on CIFAR10 and CIFAR100 with 40% noise, respectively.\nWe use our approach on three state-of-the-art CNNs: ResNext29-08-16: we consider the standard ResNext Model (Xie et al., 2017c) with a 29-layer architecture, a cardinality of 8, and a width of 16. DenseNet-12: we use DenseNet (Huang et al., 2017) with the 40- layer architecture and a growth rate of 12. ResNet50: we consider the standard ResNet model (He et al., 2016) with 50 layers. We compare against the standard networks2 as well as networks trained with DeCov diversity strategy (Cogswell et al., 2016).",

He was barely mentioned in Arnold Houbraken's major source book on 17th-century Dutch painting (Grand Theatre of Dutch Painters and Women Artists) and was thus omitted from subsequent surveys of Dutch art for nearly two centuries. In the 19th century, Vermeer was rediscovered by Gustav Friedrich Waagen and Théophile Thoré-Bürger, who published an essay attributing 66 pictures to him, although only 34 paintings are universally attributed to him today. Since that time, Vermeer's reputation has grown, and he is now acknowledged as one of the greatest painters of the Dutch Golden Age.\n\nSimilar to other major Dutch Golden Age artists such as Frans Hals and Rembrandt, Vermeer never went abroad.

        "evidence": "Natural text generation, as a key task in NLP, has been advanced substantially thanks to the flourish of neural models BIBREF0 , BIBREF1 . Typical frameworks such as sequence-to-sequence (seq2seq) have been applied to various generation tasks, including machine translation BIBREF2 and dialogue generation BIBREF3 . The standard paradigm to train such neural models is maximum likelihood estimation (MLE), which maximizes the log-likelihood of observing each word in the text given the ground-truth proceeding context BIBREF4 .\nAlthough widely used, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 : during test, the model sequentially predicts the next word conditioned on its previous generated words while during training conditioned on ground-truth words. To tackle this problem, generative adversarial networks (GAN) with reinforcement learning (RL) training approaches have been introduced to text generation tasks BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , where the discriminator is trained to distinguish real and generated text samples to provide reward signals for the generator, and the generator is optimized via policy gradient BIBREF7 .\nHowever, recent studies have shown that potential issues of training GANs on discrete data are more severe than exposure bias BIBREF14 , BIBREF15 . One of the fundamental issues when generating discrete text samples with GANs is training instability. Updating the generator with policy gradient always leads to an unstable training process because it's difficult for the generator to derive positive and stable reward signals from the discriminator even with careful pre-training BIBREF8 . As a result, the generator gets lost due to the high variance of reward signals and the training process may finally collapse BIBREF16 .\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation. At each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples. Then, inspired by reward augmented maximum likelihood (RAML) BIBREF17 , the generator is updated on the samples acquired from a stationary distribution with maximum likelihood estimation (MLE), weighted by the discriminator's rewards. This stationary distribution is designed to guarantee that training samples are surrounding the real data, thus the exploration space of our generator is indeed restricted by the MLE training objective, resulting in more stable training. Compared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient. Our contributions are mainly as follows:\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation.",

        "answer": "Tweets, retweets, mentions, replies and quotes.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nFor each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer.",

        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nOur contribution is threefold: – We model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities; – We introduce the Transformer encoder [36] in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning; – We integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.",

During this time period, Spain was officially known as the Spanish State (Estado Español).\n\nThe nature of the regime evolved and changed during its existence.

The 1937 Unification Decree, which merged all parties supporting the rebel side, led to Nationalist Spain becoming a single-party regime under the FET y de las JONS. The end of the war in 1939 brought the extension of the Franco rule to the whole country and the exile of Republican institutions. The Francoist dictatorship originally took a form described as \"fascistized dictatorship\", or \"semi-fascist regime\", showing clear influence of fascism in fields such as labor relations, the autarkic economic policy, aesthetics, and the single-party system.

For the unsupervised methods, we tested:\nAs a baseline, we used Lead-N which selects INLINEFORM0 leading sentences as the summary. For all methods, we extracted 3 sentences as the summary since it is the median number of sentences in the gold summaries that we found in our exploratory analysis.\nTable TABREF26 shows the test INLINEFORM0 score of ROUGE-1, ROUGE-2, and ROUGE-L of all the tested models described previously. The mean and standard deviation (bracketed) of the scores are computed over the 5 folds. We put the score obtained by an oracle summarizer as Oracle. Its summaries are obtained by using the true labels. This oracle summarizer acts as the upper bound of an extractive summarizer on our dataset. As we can see, in general, every scenario of NeuralSum consistently outperforms the other models significantly. The best scenario is NeuralSum with word embedding size of 300, although its ROUGE scores are still within one standard deviation of NeuralSum with the default word embedding size. Lead-3 baseline performs really well and outperforms almost all the other models, which is not surprising and even consistent with other work that for news summarization, Lead-N baseline is surprisingly hard to beat. Slightly lower than Lead-3 are LexRank and Bayes, but their scores are still within one standard deviation of each other so their performance are on par. This result suggests that a non-neural supervised summarizer is not better than an unsupervised one, and thus if labeled data are available, it might be best to opt for a neural summarizer right away. We also want to note that despite its high ROUGE, every NeuralSum scenario scores are still considerably lower than Oracle, hinting that it can be improved further. Moreover, initializing with FastText pre-trained embedding slightly lowers the scores, although they are still within one standard deviation. This finding suggests that the effect of FastText pre-trained embedding is unclear for our case.\nWe compared several summarization methods which can be categorized into three groups: unsupervised, non-neural supervised, and neural supervised methods. \nAs a baseline, we used Lead-N which selects INLINEFORM0 leading sentences as the summary. For all methods, we extracted 3 sentences as the summary since it is the median number of sentences in the gold summaries that we found in our exploratory analysis.\nLead-3 baseline performs really well and outperforms almost all the other models, which is not surprising and even consistent with other work that for news summarization, Lead-N baseline is surprisingly hard to beat.",

        "answer": "celebrity news, which explores gender in pop culture, and student reviews of computer science (CS) professors, which examines gender in academia and, particularly, the historically maledominated field of CS.",
        "evidence": "The study of gender and language has a rich history in social science. Its roots are often attributed to Robin Lakoff, who argued that language is fundamental to gender inequality, “reflected in both the ways women are expected to speak, and the ways in which women are spoken of” BIBREF2. Prominent scholars following Lakoff have included Deborah Tannen BIBREF3, Mary Bucholtz and Kira Hall BIBREF4, Janet Holmes BIBREF5, Penelope Eckert BIBREF6, and Deborah Cameron BIBREF7, along with many others.\nIn recent decades, the study of gender and language has also attracted computational researchers. Echoing Lakoff's original claim, a popular strand of computational work focuses on differences in how women and men talk, analyzing key lexical traits BIBREF8, BIBREF9, BIBREF10 and predicting a person's gender from some text they have written BIBREF11, BIBREF12. There is also research studying how people talk to women and men BIBREF13, as well as how people talk about women and men, typically in specific domains such as sports journalism BIBREF14, fiction writing BIBREF15, movie scripts BIBREF16, and Wikipedia biographies BIBREF17, BIBREF18. Our work builds on this body by diving into two novel domains: celebrity news, which explores gender in pop culture, and student reviews of CS professors, which examines gender in academia and, particularly, the historically male-dominated field of CS. Furthermore, many of these works rely on manually constructed lexicons or topics to pinpoint gendered language, but our methods automatically infer gender-associated words and labeled clusters, thus reducing supervision and increasing the potential to discover subtleties in the data.\nModeling gender associations in language could also be instrumental to other NLP tasks. Abusive language is often founded in sexism BIBREF0, BIBREF1, so models of gender associations could help to improve detection in those cases. Gender bias also manifests in NLP pipelines: prior research has found that word embeddings preserve gender biases BIBREF19, BIBREF20, BIBREF21, and some have developed methods to reduce this bias BIBREF22, BIBREF23. Yet, the problem is far from solved; for example, BIBREF24 showed that it is still possible to recover gender bias from “de-biased” embeddings. These findings further motivate our research, since before we can fully reduce gender bias in embeddings, we need to develop a deeper understanding of how gender permeates through language in the first place.\nWe also build on methods to cluster words in word embedding space and automatically label clusters. Clustering word embeddings has proven useful for discovering salient patterns in text corpora BIBREF25, BIBREF26. Once clusters are derived, we would like them to be interpretable. Much research simply considers the top-n words from each cluster, but this method can be subjective and time-consuming to interpret. Thus, there are efforts to design methods of automatic cluster labeling BIBREF27. We take a similar approach to BIBREF28, who leverage word embeddings and WordNet during labeling, and we extend their method with additional techniques and evaluations.\nOur work builds on this body by diving into two novel domains: celebrity news, which explores gender in pop culture, and student reviews of computer science (CS) professors, which examines gender in academia and, particularly, the historically maledominated field of CS.",

        "question": "Does the data synthesis for text summarization over explore?",
        "answer": "No, it does not.",
        "evidence": "Abstractive Summarization. Abstractive summarization aims to generate coherent summaries with high readability, and has seen increasing interest and improved performance due to the emergence of seq2seq models BIBREF8 and attention mechanisms BIBREF9. For example, BIBREF0, BIBREF2, and BIBREF1 in addition to using encoder-decoder model with attention, they used pointer networks to solve the out of vocabulary issue, while BIBREF0 used coverage mechanism to solve the problem of word repetition. In addition, BIBREF2 and BIBREF10 used reinforcement learning in an end-to-end setting.\nTo our knowledge, training such neural abstractive summarization models in low resource domains using domain transfer has not been thoroughly explored on domains different than news. For example, BIBREF4 reported the results of training on CNN/DM data while evaluating on DUC data without any tuning. Note that these two datasets are both in the news domain, and both consist of well written, structured documents. The domain transfer experiments of BIBREF1 similarly used two different news summarization datasets (CNN/DM and NYT). Our work differs in several ways from these two prior domain transfer efforts. First, our experiments involve two entirely different domains: news and student reflections. Unlike news, student reflection documents lack global structure, are repetitive, and contain many sentence fragments and grammatical mistakes. Second, the prior approaches either trained a part of the model using NYT data while retaining the other part of the model trained only on CNN/DM data BIBREF1, or didn't perform any tuning at all BIBREF4. In contrast, we do the training in two consecutive phases, pretraining and fine tuning. Finally, BIBREF1 reported that while training with domain transfer outperformed training only on out-of-domain data, it was not able to beat training only on in-domain data. This is likely because their in and out-of-domain data sizes are comparable, unlike in our case of scarce in-domain data.\nIn a different approach to abstractive summarization, BIBREF11 developed a soft template based neural method consisting of an end-to-end deep model for template retrieval, reranking and summary rewriting. While we also develop a template based model, our work differs in both model structure and purpose.\nData Synthesis. Data synthesis for text summarization is underexplored, with most prior work focusing on machine translation, and text normalization. BIBREF12 proposed doing data augmentation through word replacement, using WordNet BIBREF13 and vector space similarity, respectively. We will use a WordNet replacement method as a baseline synthesis method in the experiments described below. In contrast, BIBREF14 synthesized/augmented data through back-translation and word replacement using language models. BIBREF15 is another recent work that was done in parallel and is very close to ours. However, in addition to the difference in both our and their model, we think it might be infeasible to back generate student reflections from a human summary, especially an abstractive one.\nData synthesis for text summarization is underexplored, with most prior work focusing on machine translation, and text normalization.",

Our model obtains better performances in Multi-Domain scenario with an average improvement of 4.5%, where datasets are product reviews on different domains with similar sequence lengths and the same class number, thus producing stronger correlations. Multi-Cardinality scenario also achieves significant improvements of 2.77% on average, where datasets are movie reviews with different cardinalities.\nHowever, Multi-Objective scenario benefits less from multi-task learning due to lacks of salient correlation among sentiment, topic and question type. The QC dataset aims to classify each question into six categories and its performance even gets worse, which may be caused by potential noises introduced by other tasks. In practice, the structure of our model is flexible, as couplings and fusions between some empirically unrelated tasks can be removed to alleviate computation costs.\nWe further explore the influence of INLINEFORM0 in TOS on our model, which can be any positive integer. A higher value means larger and more various samples combinations, while requires higher computation costs.\nFigure FIGREF45 shows the performances of datasets in Multi-Domain scenario with different INLINEFORM0 . Compared to INLINEFORM1 , our model can achieve considerable improvements when INLINEFORM2 as more samples combinations are available. However, there are no more salient gains as INLINEFORM3 gets larger and potential noises from other tasks may lead to performance degradations. For a trade-off between efficiency and effectiveness, we determine INLINEFORM4 as the optimal value for our experiments.\nIn order to measure the correlation strength between two task INLINEFORM0 and INLINEFORM1 , we learn them jointly with our model and define Pair-wise Performance Gain as INLINEFORM2 , where INLINEFORM3 are the performances of tasks INLINEFORM4 and INLINEFORM5 when learned individually and jointly.\nWe calculate PPGs for every two tasks in Table TABREF35 and illustrate the results in Figure FIGREF47 , where darkness of colors indicate strength of correlation. It is intuitive that datasets of Multi-Domain scenario obtain relatively higher PPGs with each other as they share similar cardinalities and abundant low-level linguistic characteristics. Sentences of QC dataset are much shorter and convey unique characteristics from other tasks, thus resulting in quite lower PPGs.\nThe QC dataset aims to classify each question into six categories and its performance even gets worse, which may be caused by potential noises introduced by other tasks.",

When the Champions League was created in 1992, it was decided that a maximum of eight companies should be allowed to sponsor the event, with each corporation being allocated four advertising boards around the perimeter of the pitch, as well as logo placement at pre- and post-match interviews and a certain number of tickets to each match. This, combined with a deal to ensure tournament sponsors were given priority on television advertisements during matches, ensured that each of the tournament's main sponsors was given maximum exposure.\n\nFrom the 2012–13 knockout phase, UEFA used LED advertising hoardings installed in knock-out participant stadiums, including the final stage. From the 2015–16 season onwards, UEFA has used such hoardings from the play-off round until the final.\n\nThe tournament's main sponsors for the 2021–24 cycle are:\n\nOppo\nFedEx\nTurkish Airlines\nHeineken N.V.\nHeineken (except Albania, Azerbaijan, Bosnia and Herzegovina, France, Kazakhstan, Kosovo, Norway and Turkey)\nHeineken Silver\nJust Eat Takeaway\n10bis (Israel only)\nMenulog (Australasia only)\nBistro (Slovakia only)\nJust Eat\nDenmark\nFrance\nIreland\nItaly\nSpain\nSwitzerland\nUnited Kingdom\nLieferando (Germany and Austria only)\nPyszne (Poland only)\nGrubhub and Seamless (United States only)\nSkipTheDishes (Canada only)\nTakeaway (Belgium, Bulgaria and Luxembourg only)\nThuisbezorgd (Netherlands only)\nMastercard\nPepsiCo\nPepsi\nPepsi Max\nGatorade\nLay's (except Australasia, Balkan states, Turkey, Ireland and the United Kingdom)\nSmith's (Australasia only)\nWalkers (United Kingdom and Ireland only)\nRuffles (Turkey only)\nChipsy (Croatia, Albania, Serbia, Montenegro, Bosnia and Herzegovina, Kosovo and North Macedonia only)\nRockstar\nSony\nPlayStation 5\nSocios.com (United States only)\nAdidas is a secondary sponsor and supplies the official match ball, the Adidas Finale, and Macron supplies the referees' kit.

With this model we automatically transcribed into Arabic morphemes, roughly, 5,000 additional tokens, corresponding to the second annotation block. This can be manually annotated in at least 7,5 days, but thanks to the automatic annotation accuracy, it was manually corrected into 3 days. The accuracy of the model on the annotation of the second block was roughly 70%, which corresponds to the accuracy on the test set. The manually-corrected additional tokens were added to the training data of our neural model, and a new block was automatically annotated and manually corrected. Both accuracy on the test set and on the annotation block remained at around 70%. This is because the block added to the training data was significantly different from the previous and from the third. Adding the third block to the training data and annotating a fourth block with the new trained model gave in contrast an accuracy of roughly 80%.

        "answer": "It is the “cross-lingual pronoun prediction” task held at DiscoMT and WMT in recent years.",
        "evidence": "Pronouns can serve a variety of functions with complex cross-lingual variation BIBREF12 , and hand-picked, manually annotated test suites have been presented for the evaluation of pronoun translation BIBREF13 , BIBREF14 , BIBREF9 . While suitable for analysis, the small size of the test suites makes it hard to make statistically confident comparisons between systems, and the hand-picked nature of the test suites introduces biases. To overcome these problems, we opted for a fully automatic approach to constructing a large-scale test suite.\nConceptually, our test set is most similar to the “cross-lingual pronoun prediction” task held at DiscoMT and WMT in recent years BIBREF15 , BIBREF16 , BIBREF17 : participants are asked to fill a gap in a target sentence, where gaps correspond to pronouns.\nThe first edition of the task focused on English INLINEFORM0 French, and it was found that local context (such as the verb group) was a strong signal for pronoun prediction. Hence, future editions only provided target-side lemmas instead of fully inflected forms, which makes the task less suitable to evaluate end-to-end neural machine translation systems, although such systems have been trained on the task BIBREF18 .\n BIBREF17 do not report on the proportion of intra-sentential and inter-sentential anaphora in their test set, but the two top-performing systems only made use of intra-sentential information. Our test suite focuses on allowing the comparison of end-to-end context-aware NMT systems, and we thus extract a large number of inter-sentential anaphora, with meta-data allowing for a focus on inter-sentential anaphora with a long distance between the pronoun and its antecedent. Our focus on evaluating end-to-end NMT systems also relieves us from having to provide annotated training sets, and reduces pressure to achieve balance and full coverage of phenomena.\nAn alternative approach to automatically evaluate pronoun translation are reference-based methods that produce a score based on word alignment between source, translation output, and reference translation, and identification of pronouns in them, such as AutoPRF BIBREF19 and APT BIBREF20 . BIBREF21 perform a human meta-evaluation and show substantial disagreement between reference-based metrics and human judges, especially because there often exist valid alternative translations that use different pronouns than the reference. Our test set, and our protocol of generating contrastive examples, is focused on selected pronouns to minimize the risk of producing contrastive examples that are actually valid translations.\nConceptually, our test set is most similar to the “cross-lingual pronoun prediction” task held at DiscoMT and WMT in recent years (Hardmeier et al., 2015; Guillou et al., 2016; Loáiciga et al., 2017): participants are asked to fill a gap in a target sentence, where gaps correspond to pronouns.",

        "question": "What is The Masters?",
        "evidence": "The Masters Tournament (usually referred to as simply The Masters, or the U.S. Masters outside North America) is one of the four major championships in professional golf. Scheduled for the first full week of April, the Masters is the first major of the year, and unlike the others, it is always held at the same location, Augusta National Golf Club, a private course in the city of Augusta, Georgia, in the southeastern United States.",
        "answer": "The Masters was started by amateur champion Bobby Jones and investment banker Clifford Roberts. After his grand slam in 1930, Jones acquired the former plant nursery and co-designed Augusta National with course architect Alister MacKenzie. First played 89 years ago in 1934, the tournament is an official money event on the PGA Tour, the European Tour, and the Japan Golf Tour. The field of players is smaller than those of the other major championships because it is an invitational event, held by the Augusta National Golf Club.\n\nThe tournament has a number of traditions. Since 1949, a green jacket has been awarded to the champion, who must return it to the clubhouse one year after his victory, although it remains his personal property and is stored with other champions' jackets in a specially designated cloakroom. In most instances, only a first-time and currently reigning champion may remove his jacket from the club grounds. A golfer who wins the event multiple times uses the same green jacket awarded upon his initial win (unless they need to be re-fitted with a new jacket). The Champions Dinner, inaugurated by Ben Hogan in 1952, is held on the Tuesday before each tournament, and is open only to past champions and certain board members of the Augusta National Golf Club. Beginning in 1963, legendary golfers, usually past champions, have hit an honorary tee shot on the morning of the first round to commence play. These have included Fred McLeod, Jock Hutchinson, Gene Sarazen, Sam Snead, Byron Nelson, Arnold Palmer, Jack Nicklaus, Gary Player, Lee Elder, and Tom Watson. Since 1960, a semi-social contest at the par-3 course has been played on Wednesday, the day before the first round.\n\nNicklaus has the most Masters wins, with six between 1963 and 1986. Tiger Woods won five between 1997 and 2019. Palmer won four between 1958 and 1964. Five have won three titles at Augusta: Jimmy Demaret, Sam Snead, Gary Player, Nick Faldo, and Phil Mickelson. Player, from South Africa, was the first non-American player to win the tournament, in 1961; the second was Seve Ballesteros of Spain, the champion in 1980 and 1983.\n\nThe Augusta National course first opened 90 years ago in 1933 and has been modified many times by different architects. Among the changes: greens have been reshaped and, on occasion, entirely re-designed, bunkers have been added, water hazards have been extended, new tee boxes have been built, hundreds of trees have been planted, and several mounds have been installed.",

        "answer": "Baseball is a game that is played between two teams. The playing field is shaped like a diamond made up by four \"bases\" plus a pitching mound. Each team needs at least 9 players to occupy all field positions. Those positions are Catcher, Pitcher, First base, Second base, short stop, third base, left field, center field, and right field. The point of the game is to score more \"Runs\" than the other team. Each team takes turns trying to hit a ball pitched to them by the opposing teams pitcher. If you hit the ball you run in order from first base to second to third and then home. Once the ball is hit the other team can tag you out with the ball that you hit. Each base is a safe spot to stand so you can stop at any base and let the next person on your team try to hit the ball and advance you to the next base. If you are tagged out then your team has an out. You get three outs in an inning. Once there are three outs you switch from hitting to pitching with the other team. When you are batting you get three strikes and four balls. If the pitcher throws four balls then you can walk to first base. This is called a walk. If you swing and miss the ball, that is called a strike. You can also strike out by not swinging at a pitch that is in an imaginary strike zone. This zone is there to give the pitcher something to aim and the hitter a reasonable area to hit a ball. There are 8 innings in a game. After 8 turns being up to bat the team with more runs wins. The home team always hits last. There are lots of nuanced rules and it is most popular in the country that created it, the United States of America.",

        "question": "How many benchmark datasets do they use in the experiments?",
        "answer": "Three benchmark datasets.",
        "evidence": "Most early research on dialogue response generation focused on generating grammatical and contextually relevant responses BIBREF0, BIBREF1, BIBREF2. While promising results have been demonstrated BIBREF3, BIBREF4, syntactically coherent responses alone do not guarantee an engaging and attractive dialogue system. Expressing a unique and consistent speaking style has been shown to be crucial for increasing the user's engagement with dialogue systems BIBREF5. There are various definitions of language style BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10. In this work, from a purely computational standpoint, we refer to language style as any characteristic style of expression. Hence, our work is in line with previous work on dialogue generation with emotion BIBREF11, BIBREF12, BIBREF13, BIBREF14; response attitude BIBREF15, and speaker personality BIBREF16.\nThe aforementioned approaches explicitly incorporate the language style information into the model configuration either via embeddings or memory modules to control the process of response generation. In our replication experiments, we found that these approaches tend to overemphasise the importance of the language style. As a result, the generated responses tend to be generic and non-informative BIBREF17, but they do express a distinct style; e.g., they generate a generic response: “I am happy to hear that.\" that conveys a `happy' emotion to different queries.\nIn this work, we propose a novel prototype-to-style (PS) framework to tackle the challenge of stylistic dialogue generation. Our motivation is two-fold: (1) Human-written responses are informative and diverse, which could be leveraged as guidance for the generation model; (2) However, the retrieved response is not guaranteed to express the desired language style. Moreover, the quality of the retrieved response varies among different queries due to the instability of the IR system. Therefore, to transform the retrieved result into a relevant and stylistic response, an adequate editing process is necessary.\nAn illustration of the proposed framework is shown in Figure FIGREF2, where a prototype is first extracted from the retrieved response. The stylistic response generator then takes the desired language style and the extracted prototype as additional input to obtain an adequate and stylistic response. The proposed stylistic response generator mainly inherits from the GPT-2 model BIBREF18 which is pre-trained with a large unlabeled text corpus. However, the GPT-2 model does not naturally fit the task of dialogue generation. To this end, we design various adaptations to the model architecture to extend the GPT-2 model to address the task of dialogue generation. Furthermore, in order to control the style of the generated responses, we train the model with a novel style-aware maximum likelihood estimation (MLE) objective that encodes additional style knowledge into the model's parameters. Finally, to mitigate the possible effect that the retrieved response containing irrelevant and inappropriate information with respect to the input query, we adopt a de-noising learning strategy BIBREF19, BIBREF20 to prevent the model from uncritically copying the prototype.\nTo fully evaluate the proposed approach, we conduct extensive experiments on three benchmark datasets. Results of both human and automatic evaluation show that the proposed approach significantly outperforms several strong baselines. In addition, we also conduct an extensive cross-domain experiment to demonstrate that the proposed approach is more robust than such baselines.\nIt should be noted that stylistic dialogue generation is different from the task of text style transfer. Text style transfer aims to rewrite the input sentences such that they possess certain language styles, while rigorously preserving their semantic meaning BIBREF21. On the other hand, stylistic dialogue generation does not aim at preserving the semantic meaning of the input sentences. Instead, it aims at generating sentences that are adequate and relevant responses to the input sentences, while expressing the prespecified language styles.\nIn summary, the contributions of this work are: (1) We propose a novel framework that tackles the challenge of stylistic dialogue generation by leveraging useful information contained in the retrieved responses; (2) We propose a new stylistic response generator by making proper adaptations to a large-scale pre-trained language model. We train our model with a new style-aware learning objective in a de-noising manner. Experiments show that the proposed model outperforms many strong baselines on three benchmark datasets on both in-domain and cross-domain evaluations.\nTo fully evaluate the proposed approach, we conduct extensive experiments on three benchmark datasets.",

The oos-threshold method is a more general decision rule that can be applied to any model that produces a probability. In our evaluation, the out-of-scope threshold was chosen to be the value which yielded the highest validation score across all intents, treating out-of-scope as its own intent.\nWe use three baseline approaches for the task of predicting whether a query is out-of-scope: (1) oos-train, where we train an additional (i.e. 151st) intent on out-of-scope training data; (2) oosthreshold, where we use a threshold on the classifier’s probability estimate; and (3) oos-binary, a two-stage process where we first classify a query as in- or out-of-scope, then classify it into one of the 150 intents if classified as in-scope",

        "answer": "A neural sequential approach.",
        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nWe test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.",

        "question": "What is the target of Sentiment Analysis (SA)?",
        "answer": "It is targeting the devise and development of efficient algorithmic processes for the automatic extraction of a writer’s sentiment or emotion as conveyed in text excerpts.",
        "evidence": "In the networked-world era the production of (structured or unstructured) data is increasing with most of our knowledge being created and communicated via web-based social channels BIBREF1. Such data explosion raises the need for efficient and reliable solutions for the management, analysis and interpretation of huge data sizes. Analyzing and extracting knowledge from massive data collections is not only a big issue per-se, but also challenges the data analytics state-of-the-art BIBREF2, with statistical and machine learning methodologies paving the way, and deep learning (DL) taking over and presenting highly accurate solutions BIBREF3. Relevant applications in the field of social media cover a wide spectrum, from the categorization of major disasters BIBREF4 and the identification of suggestions BIBREF5 to inducing users’ appeal to political parties BIBREF6.\nThe raising of computational social science BIBREF7, and mainly its social media dimension BIBREF8, challenge contemporary computational linguistics and text-analytics endeavors. The challenge concerns the advancement of text analytics methodologies towards the transformation of unstructured excerpts into some kind of structured data via the identification of special passage characteristics, such as its emotional content (e.g., anger, joy, sadness) BIBREF9. In this context, Sentiment Analysis (SA) comes into play, targeting the devise and development of efficient algorithmic processes for the automatic extraction of a writer’s sentiment or emotion as conveyed in text excerpts. Relevant efforts focus on tracking the sentiment polarity of single utterances, which in most cases is loaded with a lot of subjectivity and a degree of vagueness BIBREF10. Contemporary research in the field utilizes data from social media resources (e.g., Facebook, Twitter) as well as other short text references in blogs, forums etc BIBREF11. However, users of social media tend to violate common grammar and vocabulary rules and even use various figurative language forms to communicate their message. In such situations, the sentiment inclination underlying the literal content of the conveyed concept may significantly differ from its figurative context, making SA tasks even more puzzling. Evidently, single turn text lack in detecting sentiment polarity on sarcastic and ironic expressions, as already signified in the relevant “SemEval-2014 Sentiment Analysis task 9” BIBREF12. Moreover, lacking of facial expressions and voice tone require context aware approaches to tackle such a challenging task and overcome its ambiguities BIBREF13. As sentiment is the emotion behind customer engagement, SA finds its realization in automated customer aware services, elaborating over user’s emotional intensities BIBREF14. Most of the related studies utilize single turn texts from topic specific sources, such as Twitter, Amazon, IMDB etc. Hand crafted and sentiment-oriented features, indicative of emotion polarity, are utilized to represent respective excerpt cases. The formed data are then fed traditional machine learning classifiers (e.g. SVM, Random Forest, multilayer perceptrons) or DL techniques and respective complex neural architectures, in order to induce analytical models that are able to capture the underlying sentiment content and polarity of passages BIBREF15, BIBREF16, BIBREF17.\nThe linguistic phenomenon of figurative language (FL) refers to the contradiction between the literal and the non-literal meaning of an utterance BIBREF18. Literal written language assigns ‘exact’ (or ‘real’) meaning to the used words (or phrases) without any reference to putative speech figures. In contrast, FL schemas exploit non-literal mentions that deviate from the exact concept presented by the used words and phrases. FL is rich of various linguistic phenomena like ‘metonymy’ reference to an entity stands for another of the same domain, a more general case of ‘synonymy’; and ‘metaphors’ systematic interchange between entities from different abstract domains BIBREF19. Besides the philosophical considerations, theories and debates about the exact nature of FL, findings from the neuroscience research domain present clear evidence on the presence of differentiating FL processing patterns in the human brain BIBREF20, BIBREF21, BIBREF22, BIBREF23, BIBREF14, even for woman-man attraction situations! BIBREF24. A fact that makes FL processing even more challenging and difficult to tackle. Indeed, this is the case of pragmatic FL phenomena like irony and sarcasm that main intention of in most of the cases, are characterized by an oppositeness to the literal language context. It is crucial to distinguish between the literal meaning of an expression considered as a whole from its constituents’ words and phrases. As literal meaning is assumed to be invariant in all context at least in its classical conceptualization BIBREF25, it is exactly this separation of an expression from its context that permits and opens the road to computational approaches in detecting and characterizing FL utterance.\nWe may identify three common FL expression forms namely, irony, sarcasm and metaphor. In this paper, figurative expressions, and especially ironic or sarcastic ones, are considered as a way of indirect denial. From this point of view, the interpretation and ultimately identification of the indirect meaning involved in a passage does not entail the cancellation of the indirectly rejected message and its replacement with the intentionally implied message (as advocated in BIBREF26, BIBREF27). On the contrary ironic/sarcastic expressions presupposes the processing of both the indirectly rejected and the implied message so that the difference between them can be identified. This view differs from the assumption that irony and sarcasm involve only one interpretation BIBREF28, BIBREF29. Holding that irony activates both grammatical / explicit as well as ironic / involved notions provides that irony will be more difficult to grasp than a non-ironic use of the same expression.\nDespite that all forms of FL are well studied linguistic phenomena BIBREF28, computational approaches fail to identify the polarity of them within a text. The influence of FL in sentiment classification emerged both on SemEval-2014 Sentiment Analysis task BIBREF12 and BIBREF19. Results show that Natural Language Processing (NLP) systems effective in most other tasks see their performance drop when dealing with figurative forms of language. Thus, methods capable of detecting, separating and classifying forms of FL would be valuable building blocks for a system that could ultimately provide a full-spectrum sentiment analysis of natural language.\nIn literature we encounter some major drawbacks of previous studies and we aim to resolve with our proposed method:\nMany studies tackle figurative language by utilizing a wide range of engineered features (e.g. lexical and sentiment based features) BIBREF30, BIBREF31, BIBREF0, BIBREF32, BIBREF33, BIBREF34 making classification frameworks not feasible.\nSeveral approaches search words on large dictionaries which demand large computational times and can be considered as impractical BIBREF0, BIBREF34\nMany studies exhausting preprocess the input texts, including stemming, tagging, emoji processing etc. that tend to be time consuming especially in large datasets BIBREF35, BIBREF36.\nMany approaches attempt to create datasets using social media API’s to automatically collect data rather than exploiting their system on benchmark datasets, with proven quality. To this end, it is impossible to be compared and evaluated BIBREF35, BIBREF37, BIBREF36.\nTo tackle the aforementioned problems, we propose an end-to-end methodology containing none hand crafted engineered features or lexicon dictionaries, a preprocessing step that includes only de-capitalization and we evaluate our system on several benchmark dataset. To the best of our knowledge, this is the first time that an unsupervised pre-trained Transformer method is used to capture figurative language in many of its forms.\nThe rest of the paper is structured as follows, in Section SECREF2 we present the related work on the field of FL detection, in Section SECREF3 we present our proposed method along with several state-of-the-art models that achieve high performance in a wide range of NLP tasks which will be used to compare performance, the results of our experiments are presented in Section SECREF4, and finally our conclusion is in Section SECREF5.\nIn this context, Sentiment Analysis (SA) comes into play, targeting the devise and development of efficient algorithmic processes for the automatic extraction of a writer’s sentiment or emotion as conveyed in text excerpts.",

The x-vector system yielded lower EERs on both BULATS and Linguaskill test sets.\nIn addition to the models trained on the BULATS data, it is also interesting to investigate the application of “out-of-the-box\" models for standard speaker verification tasks to this non-native speaker verification task as there is limited amounts of non-native learner English data that is publicly available. In this paper, the Kaldi-released BIBREF19 VoxCeleb x-vector/PLDA system was used as imported models, which was trained on augmented VoxCeleb 1 BIBREF17 and VoxCeleb 2 BIBREF18. There are more than 7,000 speakers in the VoxCeleb dataset with more than 2,000 hours of audio data, making it the largest publicly available speaker recognition dataset. 30 dimensional mel-frequency cepstral coefficients (MFCCs) were used as input features and system configurations were the same as the BULATS x-vector/PLDA one. It can be seen from Table TABREF10 that these out-of-domain models gave worse performance than baseline systems trained on a far smaller amount of BULATS data due to domain mismatch. Thus, two kinds of in-domain adaptation strategies were explored to make use of the BULATS training set: PLDA adaptation and x-vector extractor fine-tuning. For PLDA adaptation, x-vectors of the BULATS training set were first extracted using the VoxCeleb-trained x-vector extractor, and then employed to adapt the VoxCeleb-trained PLDA model with their mean and variance. For x-vector extractor fine-tuning, with all other layers of the VoxCeleb-trained model kept still, the output layer was re-initialised using the BULATS training set with the number of targets adjusted accordingly, and then all layers were fine-tuned on the BULATS training set. Here the PLDA adaptation system is referred to as X1 and the extractor fine-tuning system is referred to as X2. Both adaptation approaches can yield good performance gains as can be seen from Table TABREF10.

Obama previously served as a U.S. senator representing Illinois from 2005 to 2008 and as an Illinois state senator from 1997 to 2004, and worked as a civil rights lawyer before holding public office.\n\nObama was born in Honolulu, Hawaii. After graduating from Columbia University in 1983, he worked as a community organizer in Chicago. In 1988, he enrolled in Harvard Law School, where he was the first black president of the Harvard Law Review. After graduating, he became a civil rights attorney and an academic, teaching constitutional law at the University of Chicago Law School from 1992 to 2004. Turning to elective politics, he represented the 13th district in the Illinois Senate from 1997 until 2004, when he ran for the U.S. Senate. Obama received national attention in 2004 with his March Senate primary win, his well-received keynote address at the July Democratic National Convention, and his landslide November election to the Senate. In 2008, after a close primary campaign against Hillary Clinton, he was nominated by the Democratic Party for president and chose Joe Biden as his running mate. Obama was elected over Republican nominee John McCain in the presidential election and was inaugurated on January 20, 2009. Nine months later, he was named the 2009 Nobel Peace Prize laureate, a decision that drew a mixture of praise and criticism.\n\nObama's first-term actions addressed the global financial crisis and included a major stimulus package, a partial extension of George W. Bush's tax cuts, legislation to reform health care, a major financial regulation reform bill, and the end of a major US military presence in Iraq. Obama also appointed Supreme Court justices Sonia Sotomayor and Elena Kagan, the former being the first Hispanic American on the Supreme Court. He ordered the counterterrorism raid which killed Osama bin Laden and downplayed Bush's counterinsurgency model, expanding air strikes and making extensive use of special forces while encouraging greater reliance on host-government militaries.\n\nAfter winning re-election by defeating Republican opponent Mitt Romney, Obama was sworn in for a second term on January 20, 2013. In his second term, Obama took steps to combat climate change, signing a major international climate agreement and an executive order to limit carbon emissions. Obama also presided over the implementation of the Affordable Care Act and other legislation passed in his first term, and he negotiated a nuclear agreement with Iran and normalized relations with Cuba. The number of American soldiers in Afghanistan fell dramatically during Obama's second term, though U.S. soldiers remained in Afghanistan throughout Obama's presidency.\n\nDuring Obama's terms as president, the United States' reputation abroad and the American economy improved significantly, although the country experienced high levels of partisan divide. Obama left office on January 20, 2017, and continues to reside in Washington, D.C. His presidential library in Chicago began construction in 2021. Since leaving office, Obama has remained active in Democratic politics, including campaigning for candidates in various American elections. Outside of politics, Obama has published three bestselling books: Dreams from My Father (1995), The Audacity of Hope (2006) and A Promised Land (2020).

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nDistinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses.",

These approaches incorporate information about the sequential position of elements differently.\nRecurrent neural networks (RNNs) typically compute a hidden state $h_t$ , as a function of their input at time $t$ and a previous hidden state $h_{t-1}$ , capturing relative and absolute positions along the time dimension directly through their sequential structure. Non-recurrent models do not necessarily consider input elements sequentially and may hence require explicitly encoding position information to be able to use sequence order.\nOne common approach is to use position encodings which are combined with input elements to expose position information to the model. These position encodings can be a deterministic function of position BIBREF8 , BIBREF3 or learned representations. Convolutional neural networks inherently capture relative positions within the kernel size of each convolution. They have been shown to still benefit from position encodings BIBREF1 , however.\nFor the Transformer, which employs neither convolution nor recurrence, incorporating explicit representations of position information is an especially important consideration since the model is otherwise entirely invariant to sequence ordering. Attention-based models have therefore used position encodings or biased attention weights based on distance BIBREF9 .\nIn this work we present an efficient way of incorporating relative position representations in the self-attention mechanism of the Transformer. Even when entirely replacing its absolute position encodings, we demonstrate significant improvements in translation quality on two machine translation tasks.\nOur approach can be cast as a special case of extending the self-attention mechanism of the Transformer to considering arbitrary relations between any two elements of the input, a direction we plan to explore in future work on modeling labeled, directed graphs.\nEven when entirely replacing its absolute position encodings, we demonstrate significant improvements in translation quality on two machine translation tasks.",

The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest, called mediastinum .\n\nIn humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while most reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.",
        "answer": "The major structural features of the human heart are its four chambers for pumping blood. The heart is commonly viewed as having a left side and a right side, with each side comprising two chambers -- an atrium and a ventricle. The four total chambers make up the organ's primary structural features. Together, they are responsible for maintaining blood flow throughout the body via the circulatory system. The heart is also responsible for moving waste products through the bloodstream to the organs that process them.",

        "question": "Write an essay about whether corona policy measures are beneficial towards society or not",
        "evidence": "",
        "answer": "After nearly two years of the COVID-19 pandemic and yet another lockdown, many people around the Netherlands are growing restless and fed up with the restrictions. According to the Rijksoverheid, a record-breaking 74,000 cases were confirmed in the Netherlands on January 28th, with just ten corona-related ICU admissions or deaths (“Infections- Confirmed Cases”, 2022). This raises the debate: should the government continue enforcing these measures or not? In order to formulate an answer, one must first understand the virus and how it spreads, and then consider the debate from political, ethical, social and economic perspectives.\nThe first reported case of SARS-CoV-2, which causes the COVID-19 disease, was on December 31, 2019 (\"Coronavirus disease\", 2022), and it set off a chain reaction of political instability worldwide. What first started as an epidemic within China had reached almost every country in the world within months. In the last 20 years, many countries have been affected by viruses related to Covid-19 such as SARS. Because of previous experience, they took appropriate measures immediately. For example, China has had no more than 110,000 cases since the start of the pandemic, even though it has almost a population of 1.5 billion (Worldometer, 2022). However, a less politically stable country, such as Turkey, was less prepared and suffered from 12 million cases, even though it has a population of 85 million. The virus spreads very quickly because of its airborne transmission mechanism. If one is near an infected person, the carrier’s exhalation may carry the virus and can be inhaled by healthy individuals. Putting on a mask and keeping distance help prevent infected individuals from spreading virus particles into the vicinity of healthy people. However, in countries where measures were not enforced, there was a large increase in excessive deaths. The new omicron variant is proving to spread at least 20 times faster than the original strain because of its 30 mutations (Grossman and Stahel, 2022). Fortunately, it is also far less deadly because it does not attack lung tissue in its earlier stages (Zimmer and Ghorayshi, 2021).\nOne can also analyze coronavirus restrictions from an ethical perspective: should we  lower corona measures even though doing so may put more lives at risk? As of January 28th 2021, the coronavirus has a death rate of 0.51%. This is relatively high compared to other respiratory viruses such as influenza, which has a mortality rate of 0.01%. COVID-19 disproportionally affects vulnerable groups, such as those with underlying health conditions such as diabetes, obesity, or autoimmune diseases. This is especially true in the elderly, because of the increased amount of health conditions as well as an immune system deteriorated by age. The coronavirus infects the upper respiratory tract, including the lungs. It breaks into cells and orders them to create copies of the virus. The cell then bursts open and sends new copies of the virus toward other cells. Eventually, if there is not an effective immune response, the patient will perish due to lung damage, especially with the strains of COVID-19 prior to the Omicron variant. During a lockdown, there is minimal human contact, which slows down the spread of the virus. However, preventing social contact has its own devastating effects. For example, during the lockdown there were over 2.5 million children at risk of falling behind on learning (“Jongeren” 2021') (\"Education and COVID-19\", 2022). Furthermore, according to OSF Healthcare, “Average weekly visits to the emergency department for suspected suicide attempts among young girls were up more than 50% from the same period a year ago” (OSF Health Care, 2021). Thus, even though more lives are put at stake, by taking extra measures for those in the risk group, one can safely reopen society and prevent suicides and learning disbilities in the youth. Moreover, vaccines can prevent major damage to tissues from happening in the first place.\nFrom a societal perspective, coronavirus has proven to be a “splinter issue”, pushing some people into vaccine denial. Many citizens are refraining from getting vaccines without truly understanding the consequences. There are two types of vaccines: mRNA and viral vector. The mRNA COVID-19 vaccine was the first mRNA vaccine to be used in the general public. mRNA vaccines have RNA inside lipids which help the RNA enter the cell. Ribosomes read the RNA and instruct the cells to make the same spike proteins as SARS-CoV-2. The body then recognizes that the Corona spike proteins are invaders and creates antibodies to destroy them. In comparison, viral vector vaccines insert a harmless copy of the virus with the same spike protein DNA, causing the immune system to attack it and remember it. For both types of vaccines, memory B cells will continue to create antibodies in case the person gets exposed to the real virus in the future. According to Dr. Stahel, “Omicron has mutated so much that it has less affinity in terms of the antibodies from the vaccine recognizing it, so, therefore, the answer is the booster shot, because you will overwhelm the virus with the quantity of the immune response even if there is not a perfect match” (Grossman and Stahel, 2022). Thus, the original vaccine doses and, more recently, the booster shot play an important role in preventing infections, but more importantly in reducing the chance of severe illness and death. However, new studies have shown that effective immunity can wear off within six months, making it necessary to get annual doses, similar to influenza (Doucleff). 13.6% of the population over 18 refuses to get vaccinated, primarily because of distrust in the government (“Vaccinations COVID-19 vaccinations”, 2022). This limits the effects of herd immunity, a concept in which if enough people are vaccinated the virus will no longer be able to spread due to all the targets being immune.\nFinally, one must consider the economic implications of a lockdown. The lockdown caused colossal unemployment, particularly for those who worked in the travel industry. For example, according to the world economic forum, 114 million people lost their jobs during 2020 (Richter, 2021). Furthermore, the lockdowns across the world also caused an estimated 3.2 trillion euro loss in labor income. Even with the devastating economic effects, one must consider the fact that lives are put at stake when appropriate corona measures are not taken. According to NPR, there would have been approximately 488 times the number of cases in China if insufficient measures were taken, hence saving millions of lives (Beaubien, 2020). \n\tIn conclusion, by considering COVID-19 from a political, ethical, social and economic lens, I conclude that even though the virus is highly contagious and fatal towards certain groups, lockdowns are only temporary solutions. A lockdown is only beneficial to our society once excessive mortality starts rising. Hence, by taking measures early on, countries can limit the spread of the virus. For example, it took six months before mask-wearing was seen as a viable measure. As seen in the first lockdown, tens of thousands of people lost their jobs and over 2.5 million children had to do remote learning in the Netherlands (\"Jongeren\", 2021). Thus, by taking measures on time and being prepared, one need not go into lockdown. However, if the deaths start to become excessive, it is worth enforcing a proportional amount of corona measures.",

        "evidence": "Recent years have seen unprecedented progress for Natural Language Processing (NLP) on almost every NLP subtask. Even though low-resource settings have also been explored, this progress has overwhelmingly been observed in languages with significant data resources that can be leveraged to train deep neural networks. Low-resource languages still lag behind.\nEndangered languages pose an additional challenge. The process of documenting an endangered language typically includes the creation of word lists, audio and video recordings, notes, or grammar fragments, with the created resources then stored in large online linguistics archives. This process is often hindered by the Transcription Bottleneck: the linguistic fieldworker and the language community may not have time to transcribe all of the recordings and may only transcribe segments that are linguistically salient for publication or culturally significant for the creation of community resources.\nWith this work we make publicly available a large corpus in Mapudungun, a language of the indigenous Mapuche people of southern Chile and western Argentina. We hope to ameliorate the resource gap and the transcription bottleneck in two ways. First, we are providing a larger data set than has previously been available, and second, we are providing baselines for NLP tasks (speech recognition, speech synthesis, and machine translation). In providing baselines and datasets splits, we hope to further facilitate research on low-resource NLP for this language through our data set. Research on low-resource speech recognition is particularly important in relieving the transcription bottleneck, while tackling the research challenges that speech synthesis and machine translation pose for such languages could lead to such systems being deployed to serve more under-represented communities.\nFirst, we are providing a larger data set than has previously been available, and second, we are providing baselines for NLP tasks (speech recognition, speech synthesis, and machine translation).

Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer.

BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing.

        "answer": "Yes.",
        "evidence": "Over the few past years, the emergence of deep neural networks has fundamentally changed the design of entity detection systems. Consequently, recurrent neural networks (RNN) have found popularity in the field since they are able to learn long term dependencies of sequential data. The recent success of neural network based architectures principally comes from its deep structure. Training a deep neural network, however, is a difficult problem due to vanishing or exploding gradients. In order to solve this, LSTMs were proposed. An LSTM is an internal memory cell controlled by forget gate and input gate networks. A forget gate in an LSTM layer which determines how much prior memory should be passed into the next time increment. Similarly, an input gate scales new input to memory cells. Depending on the states of both gates, LSTM is able to capture long-term or short-term dependencies for sequential data. This is an ideal property for many NLP tasks.\nIt has been shown that the utilization of ELMo for different NLP tasks result in improved performance compared to other types of word embedding models such as Word2Vec (Mikolov et al., 2013), GloVe (Ma et al., 2013), and fast Text (Wang et al., 2013).",

In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data.",

        "evidence": "In this section, we will investigate the lottery image prior (LIP) property under setting i, for deep image prior (DIP) models. Model performance is measured by PSNR (Peak Signal to Noise Ratio) between the restored images and the clean ground truths (SSIM (Structural Similarity) results are in supplementary materials). We run all experiments with three different random seeds. All images used for plotting results are summarized in Fig..\nIn DIP, for each degraded image to be restored, an untrained DNN will be over-fitted over that single image (with proper early stopping). This casts a crucial difference from typical LTH settings where winning tickets are identified using IMP over a distribution of data and are verified to be effective when trained on data from that specific distribution. Therefore, besides the usual properties in winning tickets such as the existence, the superiority over other pruning methods, and the effect of rewinding, we will strive to answer two more questions about LIP in DIP. The first question is: can we extend the IMP algorithm for single-image DIP to multi-image and thus improve the performance of winning tickets hopefully? The second question is to what extend the LIP found in DIP setting can be transferred? Answering these two questions not only provides a clearer picture of LIP, but also hints a new perspective for a deeper understanding of LTH.\nIn DIP setting, we first find the winning tickets with LIP property by implementing the single-image IMP on the hourglass model (i.e., the DIP model used in. We adopt the modified objectives using clean images as labels as we discussed in Sec. 3.2. The algorithm is described in detail in Algorithm 1. We apply the implemented algorithm on Set5  ( and Set14 datasets to obtain the sparse subnetworks 1 and evaluate these subnetworks on the denoising task.\nResults of single-image IMP in Fig. (curves in red colors) verify that the LIP exists in the DIP setting. To be specific, during the IMP finding process when we use clean images in DIP objectives, we are able to find the winning tickets with LIP on untrained DNN at sparsity as high as 86.58%. While at the evaluation stage, when we only have access to the degraded images, we find that the winning tickets found with the modified objectives are still applicable, matching the dense performance at sparsity as high as 83.23%.\nBesides the dense model baselines, we also compare the single-image IMP with Random Pruning, and a pruning-at-initialization method SNIP, whose results are also presented in Fig. in other colors. Specifically, we clearly observe from the first row in Fig. that the singleimage IMP for DIP outperforms random pruning and SNIP at a wide sparsity range [20%, 96%]. Interestingly, we find random prune is a good competitor to SNIP sometimes, but both of them suffer significant performance decrease at extreme sparsities (over 80%), where IMP still persists.\nThe Effect of Weight Rewinding In this part, we study the effect of weight rewinding Is Multi-image IMP A Good Extension in DIP? DIP over-fits an untrained DNN on a single image. A reasonable conjecture is that the DNN will be dedicated to the features in that specific image and so should the resulting winning ticket be if we apply single-image IMP to the DIP model. We then ask that whether we can co-consider multiple images during IMP for DIP models to find winning tickets that are suitable for more general features and thus yield better image restoration performance? To verify our idea, we propose a new multi-image IMP for DIP where we replace the single-image DIP objective with the average of multiple images during the IMP process. Note that all images will share the same fixed random code during IMP. Otherwise, different random codes will intervene with one another because they lead to different winning tickets, resulting in a share subnetwork with inferior performance. The algorithm is formally described in Algorithm 2.\nWe evaluate the multi-image IMP in two different settings: (i) cross-domain setting where we apply the multi-image IMP to the five images from Set5; (2) single-domain setting where we apply the multi-image IMP to five images of human faces with glasses. We think images from Set 5 are from more diversified domains because they include bird, butterfly and human face contents. We compare single-image IMP winning tickets found on the Baby and the Woman images from Set5 with the cross-domain ticket, and the single-image IMP winning tickets found on Face-1 and Face-2 with the single-domain ticket. Results presented in Fig. show that multi-image IMP significantly improves the quality of the winning tickets in the cross-domain setting, which is aligned with our previous hypothesis.\nTo what extent can LIP tickets be transferred? Transferability is an important metric to measure the usefulness of LIP in the DIP setting. It would significantly undermine the practical application of LIP if the winning tickets can only be dedicatedly found for each image. In this part, we evaluate the transferability of LIP for DIP models from three perspectives, i.e., the transferability between images, between image restoration tasks and between high-level tasks.\nObservation 1: LIP can transfer across images. We identify the single-image LIPs for all image from Set5 and the multi-image LIP on Set5 using the new multi-image IMP proposed in the last part. Then we evaluate all the above LIPs on the Baby image, results being presented in Fig.. We can see that the LIPs found on other images, even those from the Bird and the Butterfly images, can perform comparably well with LIP dedicatedly found on the Baby image. This shows that LIP has reasonable transferability across images, even for those coming from slightly different domains (for example, the Baby and the Butterfly). We can also observe the fact that the multi-image LIP outperforms all single-image LIPs, as side support for the superiority of multi-image LIP in the cross-domain settings.\nObservation 2: LIP can transfer across image restoration tasks but not to other high-level tasks.  We test the denoising LIP on MNIST and CIFAR10 datasets (left 2 figures). Note that we replace the last convolutional layer of DIP models with the linear layer and load the same initial weights. We evaluate the CIFAR LIP on the denoising task.\ninterests? Furthermore, if the above question has an affirmative answer, is such transferability sustainable when transferring to or from some high-level tasks such as classification?\nTo evaluate the transferability of LIP between image restoration tasks, we first find three LIPs for the denoising, inpainting and super-resolution tasks respectively and then transfer between them, as shown in Fig.. We observe that a LIP winning ticket transferred from another image restoration task always yields restoration performance comparable with the single-image LIP found on the original task, sometimes even better, for examples in Fig.(a) and 7(g).\nWe then evaluate the transferability of LIP between the denoising task and image classification task on CIFAR-10. We apply the standard IMP on the DIP model, i.e., the hourglass architecture in, to obtain winning tickets on MNIST and CIFAR-10 datasets. We show the results of transferring the denoising LIP to MNIST in Fig.(a) and CIFAR-10 in 8(b) and the CIFAR-10 winning tickets to denoising task in Fig.). Although transferring denoising LIP to MNIST seems to yield winning tickets due to MNIST's low complexity, its transfer to CIFAR-10 is unsuccessful. Interestingly, the multi-image LIP becomes a worse ticket on CIFAR-10 than the single-image LIP. Moreover, transferring winning tickets on CIFAR-10 back to the denoising DIP task also fails to generate winning tickets that are comparable with denoising LIPs.\nBased on those observations, we conjecture that the architecture priors needed to \"win the lottery ticket\" may substantially differ between low-level (reconstruction, restoration,...) and high-level (classification, recognition,...) vision tasks, but seems to be quite overlapped/shareable among different tasks that are all low-level (or high-level). The high-level task transferability of winning tickets has been found in prior works. We believe this interesting \"incompatibility\" between low-level and high-level tasks is an unstudied new direction, and leave this for our future work.\nDatasets In setting i, we use the popular Set5 and Set14 datasets. Besides, we evaluate the transferability of subnetworks on image classification datasets such as and CIFAR10. In setting ii, our evaluation dataset is CelebA-HQ, following.\nSubnetworks Consider a network f (x; θ) parametered by θ with input x, then a subnetwork is defined as f (x; m θ), where ∈ {0, 1} d , d = ||θ|| 0 and is the element-wise product. Let A T t (f (x; θ)) to be the training algorithm, that is, training model f (x; θ) on the specific task T with t iterations. We also denote the random initialization weight as θ 0 and the pre-trained weight as θ p ; θ i as weight at the i-th training iteration and E T (f (x; θ)) the model performance evaluation.\nFinding Subnetworks Following the definitions of, we define that if the subnetworks is matching, it satisfies the following conditions (we use θ p for example, to denote a pre-trained lottery ticket; θ 0 can be defined likewise):\nThat is a matching subnetwork that performs no worse than the dense model under the same training algorithm A T and the evaluation metric E T . Similarly, we define the winning tickets: if a matching subnetwork f (x; m θ) has θ = θ p , then it is the winning tickets under the training algorithm A T .\nIn practice, we find the matching subnetworks in the following ways: 1) IMP on the dense model with only one image (applicable to the image restoration task on the same domain of images); 2) IMP on the dense model with various kinds of images through weight-sharing (applicable to the image restoration tasks on images from different domains); 3) LTH IMP on the dense model with the sub-dataset (applicable to the CS task with pre-trained GANs).\nTicket Finding Objectives When finding LIP subnetwork in untrained DNN, i.e., DIP, there is a problem that may be easily overlooked: what is the target during IMP training? Specifically, since the training target in Eq. 1 for DIP is x (the corrupted image), the model parameters may easily overfit the corrupted image during IMP training if we do not fine-tune the training epochs. Then the obtained mask will contain the information of corrupted images instead of the desired image prior (but we can also find the effective subnetworks by noisy targets, experiments are summarized in Table 3 and 4 in Supplementary Materials). Therefore, we modify the optimization objectives of DIP during IMP training: arg min θ E(f θ (z); x) to ensure that model parameters learn the clean image prior.\nEvaluations of Subnetworks After obtaining the matching subnetwork f (x; m θ), we evaluate their performances by 1) resetting the model parameter θ to initialization weight θ 0 ' 2) adding the mask m to the model; 3) training the model to another N iterations. We evaluate the DIP subnetworks performances mainly through Peak Signal to Noise Ratio (PSNR) values, plus reconstruction errors (defined in for compressive sensing with GANs.\nPruning Methods We use the standard pruning method, which iteratively prune the 20% of the model weight each time. For setting i, our basic algorithm performs IMP over just one single image (i.e., DIP's default setting), and the algorithm is summarized in Algorithm 1 (Appendix). We further design an extended algorithm, that can perform IMP for DIP over multiple images, through backbone weight sharing: the algorithm is outlined in Algorithm 2 (Appendix). We will discuss the algorithm variants in Section 4. For setting ii, we use IMP to find winning tickets in pre-trained GANs, following the routine in. In each iteration of IMP, we will first fine-tune the pre-trained GANs on a (sub-)dataset, prune 20% of the remaining weights, and reset to the pre-trained weights. Note that we also include other pruning methods to compare the effectiveness of the matching subnetworks such as random pruning (randomly generate the sparsity mask m ), and pruning-at-initialization methods, e.g., SNIP.\nIn DIP setting, we first find the winning tickets with LIP property by implementing the single-image IMP on the hourglass model (i.e., the DIP model used in Ulyanov et al. (2018). We adopt the modified objectives using clean images as labels as we discussed in Sec. 3.2. The algorithm is described in detail in Algorithm 1.****In setting i, we use the popular Set5 (Bevilacqua et al., 2012) and Set14 (Zeyde et al., 2010) datasets. Besides, we evaluate the transferability of subnetworks on image classification datasets such as MNIST (LeCun et al., 2010) and CIFAR10 (Krizhevsky et al., 2009).",

        "evidence": "In Yugoslavia, organized effort in machine translation started in 1959, but the first individual effort was made by Vladimir Matković from the Institute for Telecommunications in Zagreb in 1957 in his PhD thesis on entropy in the Croatian language BIBREF10. The main research group in machine translation was formed in 1958, at the Circle for Young Linguists in Zagreb, initiated by a young linguist Bulcsu Laszlo, who graduated in Russian language, Southern Slavic languages and English language and literature at the University of Zagreb in 1952. The majority of the group members came from different departments of the Faculty of Humanities and Social Sciences of the University of Zagreb, with several individuals from other institutions. The members from the Faculty of Humanities and Social Sciences were: Svetozar Petrović (Department of Comparative Literature), Stjepan Babić (Department of Serbo-Croatian Language and Literature), Krunoslav Pranjić (Department of Serbo-Croatian Language and Literature), Željko Bujas (Department of English Language and Literature), Malik Mulić (Department of Russian Language and Literature) and Bulcsu Laszlo (Department of Comparative Slavistics). The members of the research group from outside the Faculty of Humanities and Social Sciences were: Božidar Finka (Institute for Language of the Yugoslav Academy of Sciences and Arts), Vladimir Vranić (Center for Numerical Research of the Yugoslav Academy of Sciences and Arts), Vladimir Matković (Institute for Telecommunications), Vladimir Muljević (Institute for Regulatory and Signal Devices) BIBREF10.\nLaszlo and Petrović BIBREF11 also commented on the state of the art of the time, noting the USA prototype efforts from 1954 and the publication of a collection of research papers in 1955 as well as the USSR efforts starting from 1955 and the UK prototype from 1956. They do not detail or cite the articles they mention. However, the fact that they referred to them in a text published in 1959 (probably prepared for publishing in 1958, based on BIBREF11, where Laszlo and Petrović described that the group had started its work in 1958) leads us to the conclusion that the poorly funded Croatian research was lagging only a couple of years behind the research of the superpowers (which invested heavily in this effort). Another interesting moment, which they delineated in BIBREF11, is that the group soon discovered that some experimental work had already been done in 1957 at the Institute of Telecommunications (today a part of the Faculty of Electrical Engineering and Computing at the University of Zagreb) by Vladimir Matković. Because of this, they decided to include him in the research group of the Faculty of Humanities and Social Sciences at the University of Zagreb. The work done by Matković was documented in his doctoral dissertation but remained unpublished until 1959.\nThe Russian machine translation pioneer Andreev expressed hope that the Yugoslav (Croatian) research group could create a prototype, but sadly, due to the lack of federal funding, this never happened BIBREF10. Unlike their colleagues in the USA and the USSR, Laszlo’s group had to manage without an actual computer (which is painfully obvious in BIBREF12), and the results remained mainly theoretical. Appealing probably to the political circles of the time, Laszlo and Petrović note that, although it sounds strange, research in computational linguistics is mainly a top-priority military effort in other countries BIBREF11. There is a quote from BIBREF10 which perhaps best delineates the optimism and energy that the researchers in Zagreb had:\n\"[...] The process of translation has to mechanicalized as soon as possible, and this is only possible if a competent, fast and inexhaustible machine which could inherit the translation task is created, even if just schematic. The machine needs to think for us. If machines help humans in physical tasks, why would they not help them in mental tasks with their mechanical memory and automated logic\" (p. 118).\nLaszlo and Petrovi´c [11] considered cybernetics (as described in [29] by Wiener, who invented the term “cybernetics”) to be the best approach for machine 5 translation in the long run.",

        "answer": "To test their clusters, the authors employed the Word Intrusion task.",
        "evidence": "To test our clusters, we employed the Word Intrusion task BIBREF35. We present the annotator with five words – four drawn from one cluster and one drawn randomly from the domain vocabulary – and we ask them to pick out the intruder. The intuition is that if the cluster is coherent, then an observer should be able to identify the out-of-cluster word as the intruder. For both domains, we report results on all clusters and on the top 8, ranked by ascending normalized sum of squared errors, which can be seen as a prediction of coherence. In the celebrity domain, annotators identified the out-of-cluster word 73% of the time in the top-8 and 53% overall. In the professor domain, annotators identified it 60% of the time in the top-8 and 49% overall. As expected, top-8 performance in both domains does considerably better than overall, but at all levels the precision is significantly above the random baseline of 20%.\nTo test cluster labels, we present the annotator with a label and a word, and we ask them whether the word falls under the concept. The concept is a potential cluster label and the word is either a word from that cluster or drawn randomly from the domain vocabulary. For a good label, the rate at which in-cluster words fall under the label should be much higher than the rate at which out-of-cluster words fall under. In our experiments, we tested the top 4 predicted labels and the centroid of the cluster as a strong baseline label. The centroid achieved an in-cluster rate of .60 and out-of-cluster rate of .18 (difference of .42). Our best performing predicted label achieved an in-cluster rate of .65 and an out-of-cluster rate of .04 (difference of .61), thus outperforming the centroid on both rates and increasing the gap between rates by nearly 20 points. In the Appendix, we include more detailed results on both tasks.\nTo test our clusters, we employed the Word Intrusion task (Chang et al., 2009).",

        "evidence": "1. Slay the Nemean Lion\nHeracles defeated a lion that was attacking the city of Nemea with his bare hands. After he succeeded he wore the skin as a cloak to demonstrate his power over the opponent he had defeated.\n2. Slay the nine-headed Lernaean Hydra\nA fire-breathing monster with multiple serpent heads. When one head was cut off, two would grow in its place. It lived in a swamp near Lerna. Hera had sent it in hope it would destroy Heracles' home city because she thought it was invincible. With help from his nephew Iolaus, he defeated the monster and dipped his arrows in its poisoned blood, thus envenomizing them.\n3. Capture the Golden Hind of Artemis\nNot to kill, but to catch, this hind that was sacred to Artemis. A different, but still difficult, task for a hero. It cost time but, having chased it for a year, Heracles wore out the Hind. Artemis intervened, but as soon as Heracles explained the situation to her, she allowed him to take it, and he presented it alive to Eurystheus.\n4. Capture the Erymanthian Boar\nA fearsome marauding boar on the loose. Eurystheus set Heracles the Labour of catching it, and bringing it to Mycenae. Again, a time-consuming task, but the tireless hero found the beast, captured it, and brought it to its final spot. Patience is the heroic quality in the third and fourth Labours.\n5. Clean the Augean stables in a single day\nThe Augean stables were the home of 3,000 cattle with poisoned faeces which Augeas had been given by his father Helios. Heracles was given the near impossible task of cleaning the stables of the diseased faeces. He accomplished it by digging ditches on both sides of the stables, moving them into the ditches, and then diverting the rivers Alpheios and Pineios to wash the ditches clean.\n6. Slay the Stymphalian Birds\nThese aggressive man-eating birds were terrorizing a forest near Lake Stymphalia in northern Arcadia. Heracles scared them with a rattle given to him by Athena, to frighten them into flight away from the forest, allowing him to shoot many of them with his bow and arrow and bring back this proof of his success to Eurystheus.\n7. Capture the Cretan Bull\nThe harmful bull, father of the Minotaur, was laying waste to the lands round Knossos on Crete. It embodied the rage of Poseidon at having his gift (the Bull) to Minos diverted from the intention to sacrifice it to himself. Heracles captured it, and carried it on his shoulders to Eurystheus in Tiryns. Eurystheus released it, when it wandered to Marathon which it then terrorized, until killed by Theseus.\n8. Steal the Mares of Diomedes\nStealing the horses from Diomedes' stables that had been trained by their owner to feed on human flesh was his next challenge. Heracles' task was to capture them and hand them over to Eurystheus. He accomplished this task by feeding King Diomedes to the animals before binding their mouths shut.\n9. Obtain the girdle of Hippolyta, Queen of the Amazons\nHippolyta was an Amazon queen and she had a girdle given to her by her father Ares. Heracles had to retrieve the girdle and return it to Eurystheus. He and his band of companions received a rough welcome because, ordered by Hera, the Amazons were supposed to attack them; however, against all odds, Heracles completed the task and secured the girdle for Eurystheus.\n10. Obtain the cattle of the monster Geryon\nThe next challenge was to capture the herd guarded by a two-headed dog called Orthrus, which belonged to Geryon; a giant with three heads and six arms who lived in Erytheia. While travelling to Erytheia, he passed through the Libyan desert and was so annoyed by the heat he shot an arrow at Helios, the sun. Helios, impressed, lent him his giant cup which Heracles used to find Orthrus, the herdsman Erytion and the owner, Geryon. He killed the first two with his club and the third with a poisoned arrow. Heracles then herded the cattle and, with difficulty, took them to Eurystheus.\n11. Steal the golden apples of the Hesperides\nHercules stealing the golden apples from the Garden of the Hesperides\nThese sacred fruits were protected by Hera who had set Ladon, a fearsome hundred-headed dragon as the guardian. Heracles had to first find where the garden was; he asked Nereus for help. He came across Prometheus on his journey. Heracles shot the eagle eating at his liver, and in return he helped Heracles with knowledge that his brother would know where the garden was. His brother Atlas offered him help with the apples if he would hold up the heavens while he was gone. Atlas tricked him and did not return. Heracles returned the trickery and managed to get Atlas taking the burden of the heavens once again, and returned the apples to Mycenae.\n12. Capture and bring back Cerberus\nHis last labour and undoubtedly the riskiest. Eurystheus was so frustrated that Heracles was completing all the tasks that he had given him that he imposed one he believed to be impossible: Heracles had to go down into the underworld of Hades and capture the ferocious three-headed dog Cerberus who guarded the gates. He used the souls to help convince Hades to hand over the dog. He agreed to give him the dog if he used no weapons to obtain him. Heracles succeeded and took the creature back to Mycenae, causing Eurystheus to be fearful of the power and strength of this hero.",

        "answer": "Because the subjects are ambiguous and not descriptive for some images.",
        "evidence": "In this section, we describes procedures of building our sportball Vietnamese dataset, called UIT-ViIC.\nOur human resources for dataset construction involve five writers, whose ages are from 22-25. Being native Vietnamese residents, they are fluent in Vietnamese. All five UIT-ViIC creators first research and are trained about sports knowledge as well as the specialized vocabulary before starting to work.\nDuring annotation process, there are inconsistencies and disagreements between human's understandings and the way they see images. According to Micah Hodosh et al BIBREF5, most images’ captions on Internet nowadays tend to introduce information that cannot be obtained from the image itself, such as people name, location name, time, etc. Therefore, to successfully compose meaningful descriptive captions we expect, their should be strict guidelines.\nInspired from MS-COCO annotation rules BIBREF16, we first sketched UIT-ViIC's guidelines for our captions:\nEach caption must contain at least ten Vietnamese words.\nOnly describe visible activities and objects included in image.\nExclude name of places, streets (Chinatown, New York, etc.) and number (apartment numbers, specific time on TV, etc.)\nFamiliar English words such as laptop, TV, tennis, etc. are allowed.\nEach caption must be a single sentence with continuous tense.\nPersonal opinion and emotion must be excluded while annotating.\nAnnotators can describe the activities and objects from different perspectives.\nVisible “thing” objects are the only one to be described.\nAmbiguous “stuff” objects which do not have obvious “border” are ignored.\nIn case of 10 to 15 objects which are in the same category or species, annotators do not need to include them in the caption.\nIn comparison with MS-COCO BIBREF16 data collection guidelines in terms of annotation, UIT-ViIC’s guidelines has similar rules (1, 2, 8, 9, 10) . We extend from MS-COCO’s guidelines with five new rules to our own and have modifications in the original ones.\nIn both datasets, we would like to control sentence length and focus on describing important subjects only in order to make sure that essential information is mainly included in captions. The MS-COCO threshold for sentence’s length is 8, and we raise the number to 10 for our dataset. One reason for this change is that an object in image is usually expressed in many Vietnamese words. For example, a “baseball player” in English can be translated into “vận động viên bóng chày” or “cầu thủ bóng chày”, which already accounted for a significant length of the Vietnamese sentence. In addition, captions must be single sentences with continuous tense as we expect our model’s output to capture what we are seeing in the image in a consise way.\nOn the other hand, proper name for places, streets, etc must not be mentioned in this dataset in order to avoid confusions and incorrect identification names with the same scenery for output. Besides, annotators’ personal opinion must be excluded for more meaningful captions. Vietnamese words for several English ones such as tennis, pizza, TV, etc are not existed, so annotators could use such familiar words in describing captions. For some images, the subjects are ambiguous and not descriptive which would be difficult for annotators to describe in words. That’s the reason why annotators can describe images from more than one perspective.\nFor some images, the subjects are ambiguous and not descriptive which would be difficult for annotators to describe in words.

        "evidence": "Conventional automatic speech recognition (ASR) systems typically consist of several independently learned components: an acoustic model to predict context-dependent sub-phoneme states (senones) from audio, a graph structure to map senones to phonemes, and a pronunciation model to map phonemes to words. Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other.

        "evidence": "The proliferation of opinions expressed in online reviews, blogs, internet forums, and social media has created a pressing need for automated systems which enable customers, companies, or service providers to make informed decisions without having to absorb large amounts of opinionated text. Opinion summarization is the task of automatically generating summaries for a set of opinions about a specific target BIBREF0. Figure FIGREF1 shows various reviews about the movie “Coach Carter” and example summaries generated by humans and automatic systems. The vast majority of previous work BIBREF1 views opinion summarization as the final stage of a three-step process involving: (1) aspect extraction (i.e., finding features pertaining to the target of interest, such as battery life or sound quality); (2) sentiment prediction (i.e., determining the sentiment of the extracted aspects); and (3) summary generation (i.e., presenting the identified opinions to the user). Textual summaries are created following mostly extractive methods which select representative segments (usually sentences) from the source text BIBREF2, BIBREF3, BIBREF4, BIBREF5. Despite being less popular, abstractive approaches seem more appropriate for the task at hand as they attempt to generate summaries which are maximally informative and minimally redundant without simply rearranging passages from the original opinions BIBREF6, BIBREF7, BIBREF8, BIBREF9. General-purpose summarization approaches have recently shown promising results with end-to-end models which are data-driven and take advantage of the success of sequence-to-sequence neural network architectures. Most approaches BIBREF10, BIBREF11, BIBREF12, BIBREF13 encode documents and then decode the learned representations into an abstractive summary, often by attending to the source input BIBREF14 and copying words from it BIBREF15. Under this modeling paradigm, it is no longer necessary to identify aspects and their sentiment for the opinion summarization task, as these are learned indirectly from training data (i.e., sets of opinions and their corresponding summaries). These models are usually tested on domains where the input is either one document or a small set of documents. However, the number of opinions tends to be very large (150 for the example in Figure FIGREF1). It is therefore practically unfeasible to train a model in an end-to-end fashion, given the memory limitations of modern hardware. As a result, current approaches BIBREF16, BIBREF17, BIBREF18, BIBREF19 sacrifice end-to-end elegance in favor of a two-stage framework which we call Extract-Abstract: an extractive model first selects a subset of opinions and an abstractive model then generates the summary while conditioning on the extracted subset (see Figure FIGREF5). The extractive pass unfortunately has two drawbacks. Firstly, on account of having access to a subset of opinions, the summaries can be less informative and inaccurate, as shown in Figure FIGREF1. And secondly, user preferences cannot be easily taken into account (e.g., the reader may wish to obtain a summary focusing on the acting or plot of a movie as opposed to a general-purpose summary) since more specialized information might have been removed.\nIn this paper, we propose Condense-Abstract, an alternative two-stage framework which uses all input documents when generating the summary (see Figure FIGREF5). We view the opinion summarization problem as an instance of multi-source transduction BIBREF20; we first represent the input documents as multiple encodings, aiming to condense their meaning and distill information relating to sentiment and various aspects of the target being reviewed. These condensed representations are then aggregated using a multi-source fusion module based on which an opinion summary is generated using an abstractive model. We also introduce a zero-shot customization technique allowing users to control important aspects of the generated summary at test time. Our approach enables controllable generation while leveraging the full spectrum of opinions available for a specific target. We perform experiments on a dataset consisting of movie reviews and opinion summaries elicited from the Rotten Tomatoes website (BIBREF16; see Figure FIGREF1). Our framework outperforms state-of-the-art models by a large margin using automatic metrics and in a judgment elicitation study. We also verify that our zero-shot customization technique can effectively generate need-specific summaries.\nWe view the opinion summarization problem as an instance of multi-source transduction; we first represent the input documents as multiple encodings, aiming to condense their meaning and distill information relating to sentiment and various aspects of the target being reviewed.",

Our approach can also be viewed in connection with generative adversarial networks (GANs) BIBREF49 that is a likelihood-free framework to learn implicit generative models. However, it is non-trivial for a gradient-based method like GANs to propagate gradients through discrete structures.\nAnother related generative model class is variational auto-encoders (VAEs) (Kingma and Welling, 2013) that optimize a lower bound on the marginal data likelihood, and can be extended to learn latent structures (Miao and Blunsom, 2016; Yin et al., 2018). Against the flow-based models, VAEs remove the invertibility constraint but sacrifice the merits of exact inference and exact log likelihood computation, which potentially results in optimization challenges (Kingma et al., 2016).",

We propose an unsupervised approach which tackles all three desiderata by constraining the communication scheme to keywords extracted from a source sentence for interpretability and optimizing the efficiency-accuracy tradeoff. Our experiments show that this approach results in an autocomplete system that is 52% more accurate at a given efficiency level compared to baselines, is robust to user variations, and saves time by nearly 50% compared to typing full sentences.\nOur experiments show that this approach results in an autocomplete system that is 52% more accurate at a given efficiency level compared to baselines, is robust to user variations, and saves time by nearly 50% compared to typing full sentences.",

        "answer": "Yes, they do.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results.",

Even newer designs incorporate materials such as carbon fiber and variable-flex composites in conjunction with fiberglass and epoxy or polyester resins. Since epoxy/EPS surfboards are generally lighter, they will float better than a traditional PU/PE board of similar size, shape and thickness. This makes them easier to paddle and faster in the water. However, a common complaint of EPS boards is that they do not provide as much feedback as a traditional PU/PE board.

We find these scores remarkably high given our straight-forward average-pooling strategy and that no domain-supervision was involved in the process of learning the pre-trained representations. Figure FIGREF15 also demonstrates the quality of the obtained clusters in 2D using the BERT-base model, where the ellipses describe the mean and variance parameters learned for each cluster by the GMM with $k=5$.\nWe note that some classes of models did better than others: while all vector-based models did far better than the random and LDA baselines, the MLM-based models dominated in all cases over word2vec and the auto-regressive models. This may be explained by the fact that the MLM-based models use the entire sentence context when generating the representations for each token, while the auto-regressive models only use the past context, and word2vec uses a limited window context. Using PCA improved performance in most cases and especially for the auto-regressive models, although the results for the MLMs remain high in both cases – suggesting that these models encode the information very differently.\nWe note that some classes of models did better than others: while all vector-based models did far better than the random and LDA baselines, the MLM-based models dominated in all cases over word2vec and the auto-regressive models.",

Many people were injured, including 138 police officers. Four officers who responded to the attack died by suicide within seven months. As of July 7, 2022, monetary damages caused by attackers exceed $2.7 million.\n\nCalled to action by Trump, thousands of his supporters gathered in Washington, D.C., on January 5 and 6 to support his false claim that the 2020 election had been \"stolen by emboldened radical-left Democrats\" and to demand that Vice President Mike Pence and the Congress reject Biden's victory. Starting at noon on January 6, at a \"Save America\" rally on the Ellipse, Trump repeated false claims of election irregularities and said \"If you don't fight like hell, you're not going to have a country anymore.\" In the same speech, he said \"I know that everyone here will soon be marching over to the Capitol building to peacefully and patriotically make your voices heard.\" During and after his speech, thousands of attendees, some armed, walked to the Capitol, and hundreds breached police perimeters as Congress was beginning the electoral vote count.\n\nMore than 2,000 rioters entered the building, many of whom occupied, vandalized, and looted; assaulted Capitol Police officers and reporters; and attempted to locate lawmakers to capture and harm. A gallows was erected west of the Capitol, and some rioters chanted \"Hang Mike Pence\" after he rejected false claims by Trump and others that the vice president could overturn the election results. Some vandalized and looted the offices of House Speaker Nancy Pelosi (D‑CA) and other members of Congress. With building security breached, Capitol Police evacuated and locked down both chambers of Congress and several buildings in the Capitol Complex. Rioters occupied the empty Senate chamber while federal law enforcement officers defended the evacuated House floor. Pipe bombs were found at each of the Democratic National Committee and Republican National Committee headquarters, and Molotov cocktails were discovered in a vehicle near the Capitol.\n\nTrump resisted sending the National Guard to quell the mob. Later that afternoon, in a Twitter video, he reasserted that the election was \"fraudulent\", but told his supporters to \"go home in peace\". The Capitol was clear of rioters by mid-evening, and the counting of the electoral votes resumed and was completed in the early morning hours of January 7. Pence declared President-elect Biden and Vice President-elect Kamala Harris victorious. Pressured by his cabinet, the threat of removal, and many resignations, Trump later committed to an orderly transition of power in a televised statement.\n\nA week after the riot, the House of Representatives impeached Trump for incitement of insurrection, making him the only U.S. president to have been impeached twice. In February, after Trump had left office, the Senate voted 57–43 in favor of conviction; because this fell short of a two-thirds majority, requiring 67 votes, he was acquitted for a second time. The House passed a bill to create a bipartisan independent commission to investigate the attack, modeled after the 9/11 Commission, but it was blocked by Republicans in the Senate, so the House approved a select committee with seven Democrats and two Republicans to investigate instead. The committee held nine televised public hearings on the attack  in 2022, and later voted to subpoena Trump. By March 2022, the Justice Department's investigations had expanded to include the activities of others leading up to the attack. Ultimately, the Committee recommended Trump to DOJ to be prosecuted for obstructing an official proceeding, incitement, conspiracy to defraud the United States, and making false statements.\n\nMore than 30 members of anti-government groups, including the Oath Keepers, Proud Boys, and Three Percenters, were charged with conspiracy for allegedly planning their attacks on the Capitol; ten Oath Keepers and five Proud Boys were charged with seditious conspiracy, and one Oath Keeper pleaded guilty. Oath Keeper leader Stewart Rhodes would later be convicted of seditious conspiracy. As of January 2022, at least 57 people with roles in the day's events were running for public office. Although most people charged with crimes relating to the attack had no known affiliation with far-right or extremist groups, a significant number were linked to extremist groups or conspiratorial movements.

For human content analysis, measures of topic coherence and kernel uniqueness are both important and complement each other. Topics can be coherent but have a lot of repetitions. On the other hand, generated topics can be very diverse, but incoherent within each topic.\nTopic coherence is an automatic metric of interpretability. It was shown that the coherence measure has a high correlation with the expert estimates of topic interpretability BIBREF9 , BIBREF17 . Mimno BIBREF9 described an experiment comparing expert evaluation of LDA-generated topics and automatic topic coherence measures. It was found that most \"bad\" topics consisted of words without clear relations between each other.\nNewman et al. BIBREF6 asked users to score topics on a 3-point scale, where 3=“useful” (coherent) and 1=“useless” (less coherent). They instructed the users that one indicator of usefulness is the ease by which one could think of a short label to describe a topic. Then several automatic measures, including WordNet-based measures and corpus co-occurrence measures, were compared. It was found that the best automatic measure having the largest correlation with human evaluation is word co-occurrence calculated as point-wise mutual information (PMI) on Wikipedia articles. Later Lau et al. BIBREF17 showed that normalized poinwise mutual information (NPMI) BIBREF18 calculated on Wikipedia articles correlates even more strongly with human scores.\nWe calculate automatic topic coherence using two measure variants. The coherence of a topic is the median PMI (NPMI) of word pairs representing the topic, usually it is calculated for INLINEFORM0 most probable elements (in our study ten elements) in the topic. The coherence of the model is the median of the topic coherence. To make this measure more objective, it should be calculated on an external corpus BIBREF17 . In our case, we use Wikipedia dumps. DISPLAYFORM0 \nHuman-constructed topics usually have unique main words. The measure of kernel uniqueness shows to what extent topics are different from each other and is calculated as the number of unique elements among most probable elements of topics (kernels) in relation to the whole number of elements in kernels. DISPLAYFORM0 \nIf uniqueness of the topic kernels is closer to zero then many topics are similar to each other, contain the same words in their kernels.

        "evidence": "The argumentation mining field has been evolving very rapidly in the recent years, resulting into several workshops co-located with major NLP conferences. We first present related works with a focus on annotations and then review experiments with classifying argument components, schemes, or relations.\nOne of the first papers dealing with annotating argumentative discourse was Argumentative Zoning for scientific publications BIBREF42 . Later, Teufel.et.al.2009 extended the original 7 categories to 15 and annotated 39 articles from two domains, where each sentence is assigned a category. The obtained Fleiss' INLINEFORM0 was 0.71 and 0.65. In their approach, they tried to deliberately ignore the domain knowledge and rely only on general, rhetorical and logical aspect of the annotated texts. By contrast to our work, argumentative zoning is specific to scientific publications and has been developed solely for that task.\nReed.Rowe.2004 presented Araucaria, a tool for argumentation diagramming which supports both convergent and linked arguments, missing premises (enthymemes), and refutations. They also released the AracuariaDB corpus which has later been used for experiments in the argumentation mining field. However, the creation of the dataset in terms of annotation guidelines and reliability is not reported – these limitations as well as its rather small size have been identified BIBREF10 .\nBiran.Rambow.2011 identified justifications for subjective claims in blog threads and Wikipedia talk pages. The data were annotated with claims and their justifications reaching INLINEFORM0 0.69, but a detailed description of the annotation approach was missing.\n[p. 1078]Schneider.et.al.2013b annotated Wikipedia talk pages about deletion using 17 Walton's schemes BIBREF43 , reaching a moderate agreement (Cohen's INLINEFORM0 0.48) and concluded that their analysis technique can be reused, although “it is intensive and difficult to apply.”\nStab.Gurevych.2014 annotated 90 argumentative essays (about 30k tokens), annotating claims, major claims, and premises and their relations (support, attack). They reached Krippendorff's INLINEFORM0 0.72 for argument components and Krippendorff's INLINEFORM1 0.81 for relations between components.\nRosenthal2012 annotated sentences that are opinionated claims, in which the author expresses a belief that should be adopted by others. Two annotators labeled sentences as claims without any context and achieved Cohen's INLINEFORM0 0.50 (2,000 sentences from LiveJournal) and 0.56 (2,000 sentences from Wikipedia).\nAharoni.et.al.2014 performed an annotation study in order to find context-dependent claims and three types of context-dependent evidence in Wikipedia, that were related to 33 controversial topics. The claim and evidence were annotated in 104 articles. The average Cohen's INLINEFORM0 between a group of 20 expert annotators was 0.40. Compared to our work, the linguistic properties of Wikipedia are qualitatively different from other user-generated content, such as blogs or user comments BIBREF44 .\nWacholder.et.al.2014 annotated “argument discourse units” in blog posts and criticized the Krippendorff's INLINEFORM0 measure. They proposed a new inter-annotator metric by taking the most overlapping part of one annotation as the “core” and all annotations as a “cluster”. The data were extended by Ghosh2014, who annotated “targets” and “callouts” on the top of the units.\nPark.Cardie.2014 annotated about 10k sentences from 1,047 documents into four types of argument propositions with Cohen's INLINEFORM0 0.73 on 30% of the dataset. Only 7% of the sentences were found to be non-argumentative.\nFaulkner2014 used Amazon Mechanical Turk to annotate 8,179 sentences from student essays. Three annotators decided whether the given sentence offered reasons for or against the main prompt of the essay (or no reason at all; 66% of the sentences were found to be neutral and easy to identify). The achieved Cohen's INLINEFORM0 was 0.70.\nThe research has also been active on non-English datasets. Goudas.et.al.2014 focused on user-generated Greek texts. They selected 204 documents and manually annotated sentences that contained an argument (760 out of 16,000). They distinguished claims and premises, but the claims were always implicit. However, the annotation agreement was not reported, neither was the number of annotators or the guidelines. A study on annotation of arguments was conducted by Peldszus.Stede.2013, who evaluate agreement among 26 “naive\" annotators (annotators with very little training). They manually constructed 23 German short texts, each of them contains exactly one central claim, two premises, and one objection (rebuttal or undercut) and analyzed annotator agreement on this artificial data set. Peldszus.2014 later achieved higher inter-rater agreement with expert annotators on an extended version of the same data. Kluge.2014 built a corpus of argumentative German Web documents, containing 79 documents from 7 educational topics, which were annotated by 3 annotators according to the claim-premise argumentation model. The corpus comprises 70,000 tokens and the inter-annotator agreement was 0.40 (Krippendorff's INLINEFORM0 ). Houy.et.al.2013 targeted argumentation mining of German legal cases.\nTable TABREF33 gives an overview of annotation studies with their respective argumentation model, domain, size, and agreement. It also contains other studies outside of computational linguistics and few proposals and position papers.\nArguments in the legal domain were targeted in BIBREF11 . Using argumentation formalism inspired by Walton.2012, they employed multinomial Naive Bayes classifier and maximum entropy model for classifying argumentative sentences on the AraucariaDB corpus BIBREF45 . The same test dataset was used by Feng.Hirst.2011, who utilized the C4.5 decision classifier. Rooney.et.al.2012 investigated the use of convolution kernel methods for classifying whether a sentence belongs to an argumentative element or not using the same corpus.\nStab.Gurevych.2014b classified sentences to four categories (none, major claim, claim, premise) using their previously annotated corpus BIBREF7 and reached 0.72 macro- INLINEFORM0 score. In contrast to our work, their documents are expected to comply with a certain structure of argumentative essays and are assumed to always contain argumentation.\nBiran.Rambow.2011 identified justifications on the sentence level using a naive Bayes classifier over a feature set based on statistics from the RST Treebank, namely n-grams which were manually processed by deleting n-grams that “seemed irrelevant, ambiguous or domain-specific.”\nLlewellyn2014 experimented with classifying tweets into several argumentative categories, namely claims and counter-claims (with and without evidence) and verification inquiries previously annotated by Procter.et.al.2013. They used unigrams, punctuations, and POS as features in three classifiers.\nPark.Cardie.2014 classified propositions into three classes (unverifiable, verifiable non-experimental, and verifiable experimental) and ignored non-argumentative texts. Using multi-class SVM and a wide range of features (n-grams, POS, sentiment clue words, tense, person) they achieved Macro INLINEFORM0 0.69.\nPeldszus.2014 experimented with a rather complex labeling schema of argument segments, but their data were artificially created for their task and manually cleaned, such as removing segments that did not meet the criteria or non-argumentative segments.\nIn the first step of their two-phase approach, Goudas.et.al.2014 sampled the dataset to be balanced and identified argumentative sentences with INLINEFORM0 0.77 using the maximum entropy classifier. For identifying premises, they used BIO encoding of tokens and achieved INLINEFORM1 score 0.42 using CRFs.\nSaint-Dizier.2012 developed a Prolog engine using a lexicon of 1300 words and a set of 78 hand-crafted rules with the focus on a particular argument structure “reasons supporting conclusions” in French.\nTaking the dialogical perspective, Cabrio.Villata.2012 built upon an argumentation framework proposed by Dung.1995 which models arguments within a graph structure and provides a reasoning mechanism for resolving accepted arguments. For identifying support and attack, they relied on existing research on textual entailment BIBREF46 , namely using the off-the-shelf EDITS system. The test data were taken from a debate portal Debatepedia and covered 19 topics. Evaluation was performed in terms of measuring the acceptance of the “main argument\" using the automatically recognized entailments, yielding INLINEFORM0 score about 0.75. By contrast to our work which deals with micro-level argumentation, the Dung's model is an abstract framework intended to model dialogical argumentation.\nFinding a bridge between existing discourse research and argumentation has been targeted by several researchers. Peldszus2013a surveyed literature on argumentation and proposed utilization of Rhetorical Structure Theory (RST) BIBREF47 . They claimed that RST is by its design well-suited for studying argumentative texts, but an empirical evidence has not yet been provided. Penn Discourse Tree Bank (PDTB) BIBREF48 relations have been under examination by argumentation mining researchers too. Cabrio2013b examined a connection between five Walton's schemes and discourse markers in PDTB, however an empirical evaluation is missing.\nReed and Rowe (2004) presented Araucaria, a tool for argumentation diagramming that supports both convergent and linked arguments, missing premises (enthymemes), and refutations.",

This is because POS tags are shown to be useful features in various NLP tasks, such as named entity recognition BIBREF0 , BIBREF1 , machine translation BIBREF2 , BIBREF3 and constituency parsing BIBREF4 . Therefore, for any language, building a successful NLP system usually requires a well-performing POS tagger.\nThere are quite a number of research on Indonesian POS tagging BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 . However, almost all of them are not evaluated on a common dataset. Even when they are, their train-test split are not the same. This lack of a common benchmark dataset makes a fair comparison among these works difficult. Moreover, despite the success of neural network models for English POS tagging BIBREF9 , BIBREF10 , the use of neural networks is generally unexplored for Indonesian.

        "answer": "BioNELL is a boostrapping mechanism to bootstrap biomedical ontologies using NELL, which uses a coupled semi-supervised bootstrapping approach to extract facts from text, given an ontology and a small number of “seed” examples for each category.",
        "evidence": "Named Entity Recognition (NER) in the Biomedical domain usually includes recognition of entities such as proteins, genes, diseases, treatments, drugs, etc. Fact extraction involves extraction of Named Entities from a corpus, usually given a certain ontology. When compared to NER in the domain of general text, the biomedical domain has some characteristic challenges:\nSome of the earliest systems were heavily dependent on hand-crafted features. The method proposed in BIBREF4 for recognition of protein names in text does not require any prepared dictionary. The work gives examples of diversity in protein names and lists multiple rules depending on simple word features as well as POS tags.\n BIBREF5 adopt a machine learning approach for NER. Their NER system extracts medical problems, tests and treatments from discharge summaries and progress notes. They use a semi-Conditional Random Field (semi-CRF) BIBREF6 to output labels over all tokens in the sentence. They use a variety of token, context and sentence level features. They also use some concept mapping features using existing annotation tools, as well as Brown clustering to form 128 clusters over the unlabelled data. The dataset used is the i2b2 2010 challenge dataset. Their system achieves an F-Score of 0.85. BIBREF7 is an incremental paper on NER taggers. It uses 3 types of word-representation techniques (Brown clustering, distributional clustering, word vectors) to improve performance of the NER Conditional Random Field tagger, and achieves marginal F-Score improvements.\n BIBREF8 propose a boostrapping mechanism to bootstrap biomedical ontologies using NELL BIBREF9 , which uses a coupled semi-supervised bootstrapping approach to extract facts from text, given an ontology and a small number of “seed” examples for each category. This interesting approach (called BioNELL) uses an ontology of over 100 categories. In contrast to NELL, BioNELL does not contain any relations in the ontology. BioNELL is motivated by the fact that a lot of scientific literature available online is highly reliable due to peer-review. The authors note that the algorithm used by NELL to bootstrap fails in BioNELL due to ambiguities in biomedical literature, and heavy semantic drift. One of the causes for this is that often common words such as “white”, “dad”, “arm” are used as names of genes- this can easily result in semantic drift in one iteration of the bootstrapping. In order to mitigate this, they use Pointwise Mutual Information scores for corpus level statistics, which attributes a small score to common words. In addition, in contrast to NELL, BioNELL only uses high instances as seeds in the next iteration, but adds low ranking instances to the knowledge base. Since evaluation is not possible using Mechanical Turk or a small number of experts (due to the complexity of the task), they use Freebase BIBREF10 , a knowledge base that has some biomedical concepts as well. The lexicon learned using BioNELL is used to train an NER system. The system shows a very high precision, thereby showing that BioNELL learns very few ambiguous terms.\nMore recently, deep learning techniques have been developed to further enhance the performance of NER systems. BIBREF11 explore recurrent neural networks for the problem of NER in biomedical text.\n(Movshovitz-Attias and Cohen, 2012) propose a boostrapping mechanism to bootstrap biomedical ontologies using NELL (Carlson et al., 2010), which uses a coupled semi-supervised bootstrapping approach to extract facts from text, given an ontology and a small number of “seed” examples for each category.

Kappa scores for the identification of cyberbullying are INLINEFORM1 = 0.69 (Dutch) and INLINEFORM2 = 0.59 (English).\nAs shown in Table TABREF35 , inter-annotator agreement for the identification of the more fine-grained categories for English varies from fair to substantial BIBREF55 , except for defamation, which appears to be more difficult to recognise. No encouragements to the harasser were present in this subset of the corpus. For Dutch, the inter-annotator agreement is fair to substantial, except for curse and defamation. Analysis revealed that one of both annotators often annotated the latter as an insult, and in some cases even did not consider it as cyberbullying-related.\nIn short, the inter-rater reliability study shows that the annotation of cyberbullying is not trivial and that more fine-grained categories like defamation, curse and encouragements are sometimes hard to recognise. It appears that defamations were sometimes hard to distinguish from insults, whereas curses and exclusions were sometimes considered insults or threats. The analysis further reveals that encouragements to the harasser are subject to interpretation.

Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans. The version of LD2NL used in this paper, all experimental results will be publicly available.\nOur framework is based on a bottom-up paradigm for verbalizing SW data.",

This has the advantage that we can easily compare the performance of any two employees (or groups of employees) along any given attribute. We can correlate various performance attributes and find dependencies among them. We can also cluster employees in the workforce using their supervisor ratings for each attribute to discover interesting insights into the workforce. The HR managers in the organization considered in this paper have defined 15 attributes (Table TABREF20 ). Each attribute is essentially a work item or work category described at an abstract level. For example, FUNCTIONAL_EXCELLENCE covers any tasks, goals or activities related to the software engineering life-cycle (e.g., requirements analysis, design, coding, testing etc.) as well as technologies such as databases, web services and GUI.\nIn the example in Section SECREF4 , the first sentence (which has class STRENGTH) can be mapped to two attributes: FUNCTIONAL_EXCELLENCE and BUILDING_EFFECTIVE_TEAMS. Similarly, the third sentence (which has class WEAKNESS) can be mapped to the attribute INTERPERSONAL_EFFECTIVENESS and so forth. Thus, in order to answer the second question in Section SECREF1 , we need to map each sentence in each of the 3 classes to zero, one, two or more attributes, which is a multi-class multi-label classification problem.\nWe manually tagged the same 2000 sentences in Dataset D1 with attributes, where each sentence may get 0, 1, 2, etc. up to 15 class labels (this is dataset D2). This labelled dataset contained 749, 206, 289, 207, 91, 223, 191, 144, 103, 80, 82, 42, 29, 15, 24 sentences having the class labels listed in Table TABREF20 in the same order. The number of sentences having 0, 1, 2, or more than 2 attributes are: 321, 1070, 470 and 139 respectively. We trained several multi-class multi-label classifiers on this dataset. Table TABREF21 shows the results of 5-fold cross-validation experiments on dataset D2.\nPrecision, Recall and F-measure for this multi-label classification are computed using a strategy similar to the one described in BIBREF21 . Let INLINEFORM0 be the set of predicted labels and INLINEFORM1 be the set of actual labels for the INLINEFORM2 instance. Precision and recall for this instance are computed as follows: INLINEFORM3 \nIt can be observed that INLINEFORM0 would be undefined if INLINEFORM1 is empty and similarly INLINEFORM2 would be undefined when INLINEFORM3 is empty. Hence, overall precision and recall are computed by averaging over all the instances except where they are undefined. Instance-level F-measure can not be computed for instances where either precision or recall are undefined. Therefore, overall F-measure is computed using the overall precision and recall.\nPrecision, Recall and F-measure for this multi-label classification are computed using a strategy similar to the one described in [6].",

        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31. Besides, when node B retweets node A we have an implicit confirmation that information from A appeared in B's Twitter feed BIBREF12. Quotes are simply a special case of retweets with comments.\nMentions usually include personal conversations as they allow someone to address a specific user or to refer to an individual in the third person; in the first case they are located at the beginning of a tweet and they are known as replies, otherwise they are put in the body of a tweet BIBREF20. The network of mentions is usually seen as a stronger version of interactions between Twitter users, compared to the traditional graph of follower/following relationships BIBREF32.\nIn this work we formulate our classification problem as follows: given two classes of news articles, respectively D (disinformation) and M (mainstream), a set of news articles Ai and associated class labels Ci ∈ {D, M}, and a set of tweets Πi = {T 1 i , T2 i , ...} each of which contains an Uniform Re_x0002_source Locator (URL) pointing explicitly to article Ai , predict the class Ci of each article Ai.",

        "evidence": "Paraphrase identification is an important topic in artificial intelligence and this task justifies whether two sentences expressed in various forms are semantically similar, BIBREF0 . For example, “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend” are identified as paraphrase. This task directly benefits many industrial applications, such as plagiarism identification BIBREF0 , machine translation BIBREF1 and removing redundancy questions in Quora website BIBREF2 . Recently, there emerge many methods, such as ABCNN BIBREF3 , Siamese LSTM BIBREF2 and L.D.C BIBREF4 .\nConventionally, neural methodology aligns the sentence pair and then generates a matching score for paraphrase identification, BIBREF4 , BIBREF2 . Regarding the alignment, we conjecture that the aligned unmatched parts are semantically critical, where we define the corresponded word pairs with low similarity as aligned unmatched parts. For an example: “On Sunday, the boy runs in the yard” and “The child runs inside at the weekend”, the matched parts (i.e. (Sunday, weekend), (boy, child), run) barely make contribution to the semantic sentence similarity, but the unmatched parts (i.e. “yard” and “inside”) determine these two sentences are semantically dissimilar. For another example: “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend”, the aligned unmatched parts (i.e. “yard” and “outside”) are semantically similar, which makes the two sentences paraphrase. In conclusion, if the aligned unmatched parts are semantically consistent, the two sentences are paraphrase, otherwise they are non-paraphrase.\nTraditional alignment methods take advantage of attention mechanism BIBREF2 , which is a soft-max weighting technique. Weighting technique could pick out the most similar/dissimilar parts, but is weak in modeling the aligned unmatched parts, which are the crucial evidence to identify paraphrase. For the input sentences in Figure FIGREF1 , the weight between “Sunday” and “run” is lower than the weight between “yard” and “inside”, but the former weight is not the evidence of paraphrase/non-paraphrase, because the former two words that are most dissimilar should not be aligned for an inappropriate comparison.\nTo extract the aligned unmatched parts, in this paper, we embed Hungarian algorithm BIBREF5 into neural architecture as Hungarian layer (Algorithm SECREF7 ). Illustrated in Figure FIGREF1 , the alignment in sentence matching could be formulated as the task-assignment problem, which is tackled by Hungarian algorithm. Simply, Hungarian algorithm works out the theoretically optimal alignment relationship in an exclusive manner and the exclusiveness characterizes the aligned unmatched parts. For the example in Figure FIGREF1 , because Hungarian layer allocates the aligned pairs with exclusiveness, the matched parts (i.e (Sunday, weekend), (boy, child), run) are aligned firstly, then the word “yard” would be assigned to the word “inside” with a negative similarity, making a strong evidence for discrimination.\nSpecifically, our model performs this task in three steps. First, our model applies BiLSTM to parse the input sentences into hidden representations. Then, Hungarian layer leverages the hidden representations to extract the aligned unmatched parts. Last, we apply cosine similarity to metric the aligned unmatched parts for a final discrimination. Regarding the training process of Hungarian layer, we modify the back-propagation algorithm in both directions. In the forward pass, Hungarian layer works out the alignment relationship, according to which, the computational graph is dynamically constructed, as demonstrated in Figure FIGREF13 . Once the computational graph has been dynamically constructed, the backward propagation could be performed as usual in a conventional graph.\nWe conduct our experiments on the public benchmark dataset of “Quora Question Pairs” for the task of paraphrase identification. Experimental results demonstrate that our model outperforms other baselines extensively and significantly, which verifies our theory about the aligned unmatched parts and illustrates the effectiveness of our methodology.\nContributions. (1.) We offer a new perspective for paraphrase identification, which focuses on the aligned unmatched parts of two sentences. Accordingly, we propose the Hungarian layer to extract the aligned unmatched parts. The proposed method can achieve hard and exclusive alignments between two sequences, while we can learn parameters by end-to-end back-propagation. (2.) Our model outperforms other baselines extensively, verifying the effectiveness of our theory and method.\nOrganization. In Section 2, we survey the related work of paraphrase identification and dynamic differentiable computational graphs. In Section 3, we introduce our neural architecture. In Section 4, we conduct the experiments. In Section 5, we conclude our paper and publish our codes.\nSpecifically, our model performs this task in three steps.

On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs).

Our model achieves significant performance gains in the test sets over the baseline for both Italian and Finnish query translation. The overall low MAP for NMT can possibly be improved with larger TC. Moreover, our model validation approach requires access to RC index, and it slows down overall training process. Hence, we could not train our model for a large number of epochs - it may be another cause of the low performance.\nWe want to show that translation terms generated by our multi-task transformer are roughly equally likely to be seen in the Europarl corpus (TC) or the CLEF corpus (RC). Given a translation term INLINEFORM0 , we compute the ratio of the probability of seeing INLINEFORM1 in TC and RC, INLINEFORM2 . Here, INLINEFORM3 and INLINEFORM4 is calculated similarly. Given a query INLINEFORM5 and its translation INLINEFORM6 provided by model INLINEFORM7 , we calculate the balance of INLINEFORM8 , INLINEFORM9 . If INLINEFORM10 is close to 1, the translation terms are as likely in TC as in RC. Figure FIGREF15 shows the balance values for transformer and our model for a random sample of 20 queries from the validation set of Italian queries, respectively. Figure FIGREF16 shows the balance values for transformer and our model for a random sample of 20 queries from the test set of Italian queries, respectively. It is evident that our model achieves better balance compared to baseline transformer, except for a very few cases.\nGiven a query INLINEFORM0 , consider INLINEFORM1 as the set of terms from human translation of INLINEFORM2 and INLINEFORM3 as the set of translation terms generated by model INLINEFORM4 . We define INLINEFORM5 and INLINEFORM6 as precision and recall of INLINEFORM7 for model INLINEFORM8 . In Table TABREF19 , we report average precision and recall for both transformer and our model across our train and validation query set over two language pairs. Our model generates precise translation, i.e. it avoids terms that might be useless or even harmful for retrieval. Generally, from our observation, avoided terms are highly likely terms from TC and they are generated because of translation model overfitting. Our model achieves a regularization effect through an auxiliary task. This confirms results from existing multi-tasking literature BIBREF15 .\nTo explore translation quality, consider pair of sample translations provided by two models. For example, against an Italian query, medaglia oro super vinse medaglia oro super olimpiadi invernali lillehammer, translated term set from our model is {gold, coin, super, free, harmonising, won, winter, olympics}, while transformer output is {olympic, gold, one, coin, super, years, won, parliament, also, two, winter}. Term set from human translation is: {super, gold, medal, won, lillehammer, olypmic, winter, games}. Transformer comes up with terms like parliament, also, two and years that never appears in human translation. We found that these terms are very likely in Europarl and rare in CLEF. Our model also generates terms such as harmonising, free, olympics that not generated by transformer. However, we found that these terms are equally likely in Europarl and CLEF.\nIt is evident that our model achieves better balance compared to baseline transformer, except for a very few cases",

It is a complex process even for humans, and in fact an inability to detect sarcasm has been linked with a number of neurocognitive disorders, including dementia BIBREF0 . It is similarly a challenging open task in natural language processing, and has direct implications to a number of other critical application areas, such as sentiment analysis.\nMost research on automatic sarcasm detection to date has focused on the Twitter domain, which boasts an ample source of publicly-available data, some of which is already self-labeled by users for the presence of sarcasm (e.g., with #sarcasm). However, Twitter is highly informal, space-restricted, and subject to frequent topic fluctuations from one post to the next due to the ebb and flow of current events—in short, it is not broadly representative of most text domains. Thus, sarcasm detectors trained using features designed for maximum Twitter performance are not necessarily transferable to other domains. Despite this, it is desirable to develop approaches that can harness the more generalizable information present in the abundance of Twitter data.\nIn this work, we develop a set of domain-independent features for sarcasm detection and show that the features generally perform well across text domains.

        "question": "According to the passage, mention some of Taylor’s early albums.",
        "evidence": "Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. Her genre-spanning discography, songwriting abilities and artistic reinventions have received critical praise and wide media coverage. Born in West Reading, Pennsylvania, Swift moved to Nashville at age 14 to become a country artist. She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country artist to write a U.S. platinum-certified album.\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history. She is the most streamed woman on Spotify and the only act to have five albums open with over one million copies sold in the US. Among her accolades are 12 Grammy Awards, including three Album of the Year wins; an Emmy Award; 40 American Music Awards; 29 Billboard Music Awards; three IFPI Global Recording Artist of the Year awards; and 92 Guinness World Records. Swift has been featured in rankings such as Rolling Stone's 100 Greatest Songwriters of All Time, Billboard's Greatest of All Time Artists, the Time 100 and Forbes Celebrity 100. Honored with titles such as Artist of the Decade and Woman of the Decade, Swift is an advocate for artists' rights and women's empowerment. Her music is credited with influencing a generation of singers and songwriters.",

The jaws were tipped with a deep, narrow beak, believed to have been better at grasping and plucking than biting.\n\nTriceratops teeth were arranged in groups called batteries, of 36 to 40 tooth columns in each side of each jaw, with 3 to 5 stacked teeth per column, depending on the size of the animal. This gives a range of 432 to 800 teeth, of which only a fraction were in use at any given time (Tooth replacement was continuous throughout the life of the animal). They functioned by shearing in a vertical to near-vertical orientation. The great size and numerous teeth of Triceratops suggests that they ate large volumes of fibrous plant material, with some researchers suggesting palms and cycads, and others suggesting ferns, which then grew in prairies.",

        "question": "What network do they use to learn baseline event embedding?",
        "answer": "A neural tensor network.",
        "evidence": "Events are a kind of important objective information of the world. Structuralizing and representing such information as machine-readable knowledge are crucial to artificial intelligence BIBREF0, BIBREF1. The main idea is to learn distributed representations for structured events (i.e. event embeddings) from text, and use them as the basis to induce textual features for downstream applications, such as script event prediction and stock market prediction.\nParameterized additive models are among the most widely used for learning distributed event representations in prior work BIBREF2, BIBREF3, which passes the concatenation or addition of event arguments' word embeddings to a parameterized function. The function maps the summed vectors into an event embedding space. Furthermore, BIBREF4 ding2015deep and BIBREF5 weber2018event propose using neural tensor networks to perform semantic composition of event arguments, which can better capture the interactions between event arguments.\nThis line of work only captures shallow event semantics, which is not capable of distinguishing events with subtle differences. On the one hand, the obtained event embeddings cannot capture the relationship between events that are syntactically or semantically similar, if they do not share similar word vectors. For example, as shown in Figure FIGREF2 (a), “PersonX threw bomb” and “PersonZ attacked embassy”. On the other hand, two events with similar word embeddings may have similar embeddings despite that they are quite unrelated, for example, as shown in Figure FIGREF2 (b), “PersonX broke record” and “PersonY broke vase”. Note that in this paper, similar events generally refer to events with strong semantic relationships rather than just the same events.\nOne important reason for the problem is the lack of the external commonsense knowledge about the mental state of event participants when learning the objective event representations. In Figure FIGREF2 (a), two event participants “PersonY” and “PersonZ” may carry out a terrorist attack, and hence, they have the same intent: “to bloodshed”, which can help representation learning model maps two events into the neighbor vector space. In Figure FIGREF2 (b), a change to a single argument leads to a large semantic shift in the event representations, as the change of an argument can result in different emotions of event participants. Who “broke the record” is likely to be happy, while, who “broke a vase” may be sad. Hence, intent and sentiment can be used to learn more fine-grained semantic features for event embeddings.\nSuch commonsense knowledge is not explicitly expressed but can be found in a knowledge base such as Event2Mind BIBREF6 and ATOMIC BIBREF7. Thus, we aim to incorporate the external commonsense knowledge, i.e., intent and sentiment, into the learning process to generate better event representations. Specifically, we propose a simple and effective model to jointly embed events, intents and emotions into the same vector space. A neural tensor network is used to learn baseline event embeddings, and we define a corresponding loss function to incorporate intent and sentiment information.\nExtensive experiments show that incorporating external commonsense knowledge brings promising improvements to event embeddings, achieving 78% and 200% improvements on hard similarity small and big dataset, respectively. With better embeddings, we can achieve superior performances on script event prediction and stock market prediction compared to state-of-the-art baseline methods.\nA neural tensor network is used to learn baseline event embeddings, and we define a corresponding loss function to incorporate intent and sentiment information.",

        "answer": "Yes.",
        "evidence": "All BERT experiments were trained for 500K steps. The code was written in Python and we used the Tensorflow libraries to create the models. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. The data was first processed into Tensorflow records as the input to the model. The set of hyperparameters which we found optimal after experimenting with different sets are in (Table TABREF10).\nThis set of parameters were chosen as there training performances were better than smaller models on modelling the long sequences of sub-words. We use the Adam optimizer BIBREF16 same as the English BERT. A maximum sequence length of 300 encompasses 98 percent of the training data and also allows us to fit larger models on the GPU card. Hyper-parameter optimization is very difficult in case of these models as they take around 15 days to train given the resources. The hyperparameter choices were therefore more dependant on the original BERT with little tweaks. We assess the training performance of the the model in the (Table TABREF11).\nWhen we train the BERT model we mask some percentage of the input tokens at random, and then predict those masked tokens, this is known as Masked LM. The masked LM loss, refers specifically to the loss when the masked language model predicts on the masked tokens. The masked LM accuracy refers specifically to the accuracy with which the model predicts on the masked tokens. The loss for both the models are far off from the Masked LM loss of the English BERT, key difference being the pre-training data for both the language models are quite different. Google training their model on 3.3 Billion words from BooksCorpus BIBREF17 and the English Wikipedia and our model being trained on 144 million words. Comparing the two Finnish models, the left-marked model has a better training performance than left+right-marked model.\nThe results of the pseudo-perplexity described in the previous section to evaluate the above models on the test data-set is in table (Table TABREF12).The test dataset is of a different context when compared to the training data, and interestingly both the models are quite confident when it comes to the test dataset. The pseudo-perplexity values of left-marked are lower when compared to left-right-marked signifying that it is more confident.\nWe cannot directly compare the perplexity scores BERT model with a unidirectional LSTM model as both are calculated in a different manner. We can experiment to compare it with a Bi-directional LSTM or use a downstreaming task to compare both the performances. We could also randomly mask tokens and then compare the prediction accuracy on the masked tokens.\nAll Transformer-XL experiments are also trained equally for 500K steps. The code was written in Python and we used the PyTorch libraries for model creation. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. Two sets of hyperparameters were chosen to be compared after some initial optimization and are in (Table TABREF14)\nFrom the above parameter choice, we wanted to experiment, whether providing more Segment and Memory length is advantageous (longer context) than a larger model. These parameters where chosen after some hyperparameter optimization. Same as for BERT we use the Adam optimizer, but we also use a cosine annealing learning rate scheduler to speed-up training BIBREF18. The training performance results are in (Table TABREF15)\nAs opposed to BERT, the left+right-marked models have a better training performance than their counterpart. Interestingly the larger model trains much better when compared to providing larger contexts. The same set of parameters for the 32-32 model cannot be replicated for 150-150 model as the latter takes a lot of space on the GPU card. The test set is same as that used with BERT and the results are in (Table TABREF16). The test performance is similar to that of the training performance with left-right-marked large model(32-32) performing the best. We can directly compare the perplexity scores with the previous best BIBREF19 as both are unidirectional models, Transformer-XL model has outperformed the latter by 27%.\nTransformer-XL and BERT both have low perplexity and pseudo-perplexity scores, but both cannot be directly compared as they are calculated quite differently (Eq.DISPLAY_FORM4, Eq.DISPLAY_FORM6). The dramatically low scores of BERT indicate that per word predicted probability is higher than that of a uni-directional model. Thus the predicted word probability distribution is much sharper when compared to the XL model probability distribution. At this point, we cannot say which model architecture has performed better- BERT or Transformer-XL, despite both of them achieving good low perplexity scores. We would need to experiment with a downstreaming task in-order to fairly compare model performances.\nThe dramatically low scores of BERT indicate that per word predicted probability is higher than that of a uni-directional model.

Deep learning architectures used in the literature include Recurrent Neural Networks (RNNs), Convolutional Neural Networks (CNNs), Transformers, and Graph Neural Networks (GNNs). N-BEATS deeply stacks fully-connected layers with backward and forward residual links for univariate times series forecasting. TCN utilizes a deep CNN architecture with dilated causal convolutions. Considering both long-term dependencies and short-term trends in multivariate time series, LSTnet combines both CNNs and RNNS in a unified model. LogTrans brings the Transformer model to time series forecasting with causal convolution in its attention mechanism. Informer further proposes a sparse self-attention mechanism to reduce the time complexity and memory usage. StemGNN is a GNN based model that considers the intra-temporal and inter-series correlations simultaneously. Unlike these works, we aim to learn general representations for time series data that can not only be used for forecasting but also other tasks, such as classification. Besides, the proposed framework is compatible with various architectures as encoders.\nTime series forecasting aims to predict the future L y time stamps, with the last L x observations. We follow to train a linear model regularized with the L2 norm penalty to make predictions. The output has dimension L y in the univariate case and L y × F for the multivariate case, where F is the feature dimension.\nDatasets and Baselines. Four benchmark datasets for time series forecasting are adopted, including ETTh1, ETTh2, ETTm1, and the Electricity dataset. These datasets are used in both univariate and multivariate settings.

Secondly, sarcastic sentences are known to include polarity shifts in sentimental and emotional degrees.",
        "evidence": "CNN can automatically extract key features from the training data. It grasps contextual local features from a sentence and, after several convolution operations, it forms a global feature vector out of those local features. CNN does not need the hand-crafted features used in traditional supervised classifiers. Such hand-crafted features are difficult to compute and a good guess for encoding the features is always necessary in order to get satisfactory results. CNN, instead, uses a hierarchy of local features which are important to learn context. The hand-crafted features often ignore such a hierarchy of local features.\nFeatures extracted by CNN can therefore be used instead of hand-crafted features, as they carry more useful information. The idea behind convolution is to take the dot product of a vector of INLINEFORM0 weights INLINEFORM1 also known as kernel vector with each INLINEFORM2 -gram in the sentence INLINEFORM3 to obtain another sequence of features INLINEFORM4 . DISPLAYFORM0 \nThus, a max pooling operation is applied over the feature map and the maximum value INLINEFORM0 is taken as the feature corresponding to this particular kernel vector. Similarly, varying kernel vectors and window sizes are used to obtain multiple features BIBREF32 . For each word INLINEFORM1 in the vocabulary, a INLINEFORM2 -dimensional vector representation is given in a look up table that is learned from the data BIBREF33 . The vector representation of a sentence, hence, is a concatenation of vectors for individual words. Similarly, we can have look up tables for other features. One might want to provide features other than words if these features are suspected to be helpful. The convolution kernels are then applied to word vectors instead of individual words.\nWe use these features to train higher layers of the CNN, in order to represent bigger groups of words in sentences. We denote the feature learned at hidden neuron INLINEFORM0 in layer INLINEFORM1 as INLINEFORM2 . Multiple features may be learned in parallel in the same CNN layer. The features learned in each layer are used to train the next layer: DISPLAYFORM0 \nwhere * indicates convolution and INLINEFORM0 is a weight kernel for hidden neuron INLINEFORM1 and INLINEFORM2 is the total number of hidden neurons. The CNN sentence model preserves the order of words by adopting convolution kernels of gradually increasing sizes that span an increasing number of words and ultimately the entire sentence. As mentioned above, each word in a sentence is represented using word embeddings.\nWe employ the publicly available word2vec vectors, which were trained on 100 billion words from Google News. The vectors are of dimensionality 300, trained using the continuous bag-of-words architecture BIBREF33 . Words not present in the set of pre-trained words are initialized randomly. However, while training the neural network, we use non-static representations. These include the word vectors, taken as input, into the list of parameters to be learned during training.\nTwo primary reasons motivated us to use non-static channels as opposed to static ones. Firstly, the common presence of informal language and words in tweets resulted in a relatively high random initialization of word vectors due to the unavailability of these words in the word2vec dictionary. Secondly, sarcastic sentences are known to include polarity shifts in sentimental and emotional degrees. For example, “I love the pain present in breakups\" is a sarcastic sentence with a significant change in sentimental polarity. As word2vec was not trained to incorporate these nuances, we allow our models to update the embeddings during training in order to include them. Each sentence is wrapped to a window of INLINEFORM0 , where INLINEFORM1 is the maximum number of words amongst all sentences in the dataset. We use the output of the fully-connected layer of the network as our feature vector.\nWe have done two kinds of experiments: firstly, we used CNN for the classification; secondly, we extracted features from the fully-connected layer of the CNN and fed them to an SVM for the final classification. The latter CNN-SVM scheme is quite useful for text classification as shown by Poria et al. BIBREF18 . We carry out n-fold cross-validation on the dataset using CNN. In every fold iteration, in order to obtain the training and test features, the output of the fully-connected layer is treated as features to be used for the final classification using SVM.

The approach has remained largely the same during this time, with the underlying coding procedures not updating to reflect changes in natural language processing (NLP) technology. These NLP technologies have now advanced to such a level, and with accompanying open-source software implementations, that their inclusion in the event-data coding process comes as an obvious advancement. When combined with changes in how news content is obtained, the ability to store and process large amounts of text, and enhancements based on two decades worth of event-data experience, it becomes clear that political event data is ready for a next generation dataset.\nIn this chapter, I provide the technical details for creating such a next-generation dataset. The technical details lead to a pipeline for the production of the Phoenix event dataset. The Phoenix dataset is a daily updated, near-real-time political event dataset. The coding process makes use of open-source NLP software, an abundance of online news content, and other technical advances made possible by open-source software. This enables a dataset that is transparent and replicable, while providing a more accurate coding process than previously possible. Additionally, the dataset's near-real-time nature also enables many applications that were previously impossible with batch-updated datasets, such as monitoring of ongoing events. Thus, this dataset provides a significant improvement over previous event data generation efforts.\nIn the following sections I briefly outline the history of computer-generated political event data to this point in history.

        "evidence": "UTF8gkai With the widespread of electronic health records (EHRs) in recent years, a large number of EHRs can be integrated and shared in different medical environments, which further support the clinical decision making and government health policy formulationBIBREF0. However, most of the information in current medical records is stored in natural language texts, which makes data mining algorithms unable to process these data directly. To extract relational entity triples from the text, researchers generally use entity and relation extraction algorithm, and rely on the central word to convert the triples into key-value pairs, which can be processed by conventional data mining algorithms directly. Fig. FIGREF1 shows an example of entity and relation extraction in the text of EHRs. The text contains three relational entity triples, i.e., $<$咳嗽, 程度等级, 反复$>$ ($<$cough, degree, repeated$>$), $<$咳痰, 程度等, 反复$>$ ($<$expectoration, degree, repeated$>$) and $<$发热, 存在情况, 无$>$ ($<$fever, presence, nonexistent$>$). By using the symptom as the central word, these triples can then be converted into three key-value pairs, i.e., $<$咳嗽的程度等级, 反复$>$ ($<$degree of cough, repeated$>$), $<$咳痰的程度等级, 反复$>$ ($<$degree of expectoration, repeated$>$) and $<$发热的存在情况, 无$>$ ($<$presence of fever, nonexistent$>$).\nUTF8gkai To solve the task of entity and relation extraction, researchers usually follows pipeline processing and split the task into two sub-tasks, namely named entity recognition (NER)BIBREF1 and relation classification (RC)BIBREF2, respectively.\nHowever, this pipeline method usually fails to capture joint features between entity and relationship types. For example, for a valid relation “存在情况(presence)” in Fig. FIGREF1, the types of its two relational entities must be “疾病(disease)”, “症状(symptom)” or “存在词(presence word)”. To capture these joint features, a large number of joint learning models have been proposed BIBREF3, BIBREF4, among which bidirectional long short term memory (Bi-LSTM) BIBREF5, BIBREF6 are commonly used as the shared parameter layer. However, compared with the language models that benefit from abundant knowledge from pre-training and strong feature extraction capability, Bi-LSTM model has relatively lower generalization performance.\nTo improve the performance, a simple solution is to incorporate language model into joint learning as a shared parameter layer. However, the existing models only introduce language models into the NER or RC task separately BIBREF7, BIBREF8. Therefore, the joint features between entity and relationship types still can not be captured. Meanwhile, BIBREF9 considered the joint features, but it also uses Bi-LSTM as the shared parameter layer, resulting the same problem as discussed previously.\nGiven the aforementioned challenges and current researches, we propose a focused attention model based on widely known BERT language model BIBREF10 to jointly for NER and RC tasks. Specifically, through the dynamic range attention mechanism, we construct task-specific MASK matrix to control the attention range of the last $K$ layers in BERT language model, leading to the model focusing on the words of the task. This process helps obtain the corresponding task-specific context-dependent representations. In this way, the modified BERT language model can be used as the shared parameter layer in joint learning NER and RC task. We call the modified BERT language model shared task representation encoder (STR-encoder) in the following paper.\nTo sum up, the main contributions of our work are summarized as follows:\nWe propose a focused attention model to jointly learn NER and RC task. The model integrates BERT language model as a shared parameter layer to achieve better generalization performance.\nIn the proposed model, we incorporate a novel structure, called STR-encoder, which changes the attention range of the last $K$ layers in BERT language model to obtain task-specific context-dependent representations. It can make full use of the original structure of BERT to produce the vector of the task, and can directly use the prior knowledge contained in the pre-trained language model.\nFor RC task, we proposed two different MASK matrices to extract the required feature representation of RC task. The performances of these two matrices are analyzed and compared in the experiment.\nThe rest of the paper is organized as follows. We briefly review the related work on NER, RC and joint entity and relation extraction in Section SECREF2. In Section SECREF3, we present the proposed focused attention model. We report the experimental results in Section SECREF4. Section SECREF5 is dedicated to studying several key factors that affect the performance of our model.

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis).

Along with Hong Kong, South Korea, and Taiwan, Singapore is one of the Four Asian Tigers, and has surpassed its peers in terms of Gross Domestic Product (GDP) per capita. Between 1965 and 1995, growth rates averaged around 6 per cent per annum, transforming the living standards of the population.\n\nThe Singaporean economy is regarded as free, innovative, dynamic and business-friendly. For several years, Singapore has been one of the few countries with an AAA credit rating from the big three, and the only Asian country to achieve this rating. Singapore attracts a large amount of foreign investment as a result of its location, skilled workforce, low tax rates, advanced infrastructure and zero-tolerance against corruption. It is the world's most competitive economy in 2019, according to the World Economic Forum's ranking of 141 countries, with the 2nd highest GDP per capita. Roughly 44 percent of the Singaporean workforce is made up of non-Singaporeans. Despite market freedom, Singapore's government operations have a significant stake in the economy, contributing 22% of the GDP. The city is a popular location for conferences and events.\n\nThe currency of Singapore is the Singapore dollar (SGD or S$), issued by the Monetary Authority of Singapore (MAS). It has been interchangeable with the Brunei dollar at par value since 1967. MAS manages its monetary policy by allowing the Singapore dollar exchange rate to rise or fall within an undisclosed trading band. This is different from most central banks, which use interest rates to manage policy. Singapore has the world's eleventh largest foreign reserves, and one of the highest net international investment position per capita.\n\nSingapore has been identified as a tax haven for the wealthy due to its low tax rates on personal income and tax exemptions on foreign-based income and capital gains. Individuals such as Australian millionaire retailer Brett Blundy and multi-billionaire Facebook co-founder Eduardo Saverin are two examples of wealthy individuals who have settled in Singapore. In 2009, Singapore was removed from the Organisation for Economic Co-operation and Development (OECD) \"liste grise\" of tax havens, and ranked fourth on the Tax Justice Network's 2015 Financial Secrecy Index of the world's off-shore financial service providers, banking one-eighth of the world's offshore capital, while \"providing numerous tax avoidance and evasion opportunities\". In August 2016, The Straits Times reported that Indonesia had decided to create tax havens on two islands near Singapore to bring Indonesian capital back into the tax base. In October 2016, the Monetary Authority of Singapore admonished and fined UBS and DBS and withdrew Falcon Private Bank's banking licence for their alleged role in the Malaysian Sovereign Fund scandal.\n\n\nPanoramic view of the Central Business District\nSingapore has the world's highest percentage of millionaires, with one out of every six households having at least one million US dollars in disposable wealth. This excludes property, businesses, and luxury goods, which if included would increase the number of millionaires, especially as property in Singapore is among the world's most expensive. In 2016, Singapore was rated the world's most expensive city for the third consecutive year by the Economist Intelligence Unit, and this remained true in 2018. The government provides numerous assistance programmes to the homeless and needy through the Ministry of Social and Family Development, so acute poverty is rare.

He taught a high school in Canaan, Conn., until the spring of 1837, when he began law studies with Judge Arphaxad Loomis, of Little Falls, New York. Upon his admission to the bar in 1839, he decided to emigrate to the West. He selected St. Louis and arrived there in November, 1839, beginning practice in March, 1840. He gave special attention to questions affecting real property, and achieved distinguished success in litigated cases of this nature. Through apprehensions with regard to his health, he retired in 1860, at a comparatively early age, from active practice, confining himself thereafter to office consultations. He declined all political nominations until 1854, when he was elected to the Missouri House of Representatives. In 1860 he was an unsuccessful candidate for US Congress on the Bell and Everett ticket. In 1875, he was a member of the convention which revised the Constitution of Missouri. He was a director of Washington University, in St. Louis, and served gratuitously for fifteen years in its Law Department as lecturer.

        "evidence": "Semantic Role Labeling (SRL) has emerged as an important task in Natural Language Processing (NLP) due to its applicability in information extraction, question answering, and other NLP tasks. SRL is the problem of finding predicate-argument structure in a sentence, as illustrated below:\n INLINEFORM0 \nHere, the predicate WRITE has two arguments: `Mike' as A0 or the writer, and `a book' as A1 or the thing written. The labels A0 and A1 correspond to the PropBank annotations BIBREF0 .\nAs the need for SRL arises in different domains and languages, the existing manually annotated corpora become insufficient to build supervised systems. This has motivated work on unsupervised SRL BIBREF1 , BIBREF2 , BIBREF3 . Previous work has indicated that unsupervised systems could benefit from the word alignment information in parallel text in two or more languages BIBREF4 , BIBREF5 , BIBREF6 . For example, consider the German translation of sentence INLINEFORM0 :\n INLINEFORM0 \nIf sentences INLINEFORM0 and INLINEFORM1 have the word alignments: Mike-Mike, written-geschrieben, and book-Buch, the system might be able to predict A1 for Buch, even if there is insufficient information in the monolingual German data to learn this assignment. Thus, in languages where the resources are sparse or not good enough, or the distributions are not informative, SRL systems could be made more accurate by using parallel data with resource rich or more amenable languages.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages. The model consists of individual Bayesian models for each language BIBREF3 , and crosslingual latent variables to incorporate soft role agreement between aligned constituents. This latent variable approach has been demonstrated to increase the performance in a multilingual unsupervised part-of-speech tagging model based on HMMs BIBREF4 . We investigate the application of this approach to unsupervised SRL, presenting the performance improvements obtained in different settings involving labeled and unlabeled data, and analyzing the annotation effort required to obtain similar gains using labeled data.\nWe begin by briefly describing the unsupervised SRL pipeline and the monolingual semantic role induction model we use, and then describe our multilingual model.\nThe model consists of individual Bayesian models for each language , and crosslingual latent variables to incorporate soft role agreement between aligned constituents.",

Although ultimate resembles many traditional sports in its athletic requirements, it is unlike most sports due to its focus on self-officiating, even at the highest levels of competition. The term \"frisbee\" is a registered trademark of the Wham-O toy company, and thus the sport is not formally called \"ultimate Frisbee\", though this name is still in common casual use. Points are scored by passing the disc to a teammate in the opposing end zone. Other basic rules are that players must not take steps while holding the disc, and interceptions, incomplete passes, and passes out of bounds are turnovers.

        "evidence": "As mentioned earlier, although research on cyberbullying detection is more limited than social studies on the phenomenon, some important advances have been made in recent years. In what follows, we present a brief overview of the most important natural language processing approaches to cyberbullying detection.\nAlthough some studies have investigated the effectiveness of rule-based modelling BIBREF31 , the dominant approach to cyberbullying detection involves machine learning. Most machine learning approaches are based on supervised BIBREF32 , BIBREF33 , BIBREF34 or semi-supervised learning BIBREF35 . The former involves the construction of a classifier based on labeled training data, whereas semi-supervised approaches rely on classifiers that are built from a training corpus containing a small set of labeled and a large set of unlabelled instances (a method that is often used to handle data sparsity). As cyberbullying detection essentially involves the distinction between bullying and non-bullying posts, the problem is generally approached as a binary classification task where the positive class is represented by instances containing (textual) cyberbullying, while the negative class includes instances containing non-cyberbullying or `innocent' text.\nA key challenge in cyberbullying research is the availability of suitable data, which is necessary to develop models that characterise cyberbullying. In recent years, only a few datasets have become publicly available for this particular task, such as the training sets provided in the context of the CAW 2.0 workshop and more recently, the Twitter Bullying Traces dataset BIBREF36 . As a result, several studies have worked with the former or have constructed their own corpus from social media websites that are prone to bullying content, such as YouTube BIBREF32 , BIBREF33 , Formspring BIBREF33 , and ASKfm BIBREF37 (the latter two are social networking sites where users can send each other questions or respond to them). Despite the bottleneck of data availability, existing approaches to cyberbullying detection have shown its potential, and the relevance of automatic text analysis techniques to ensure child safety online has been recognised BIBREF38 , BIBREF39 .\nAmong the first studies on cyberbullying detection are BIBREF34 , BIBREF31 , BIBREF33 , who explored the predictive power of INLINEFORM0 -grams (with and without tf-idf weighting), part-of-speech information (e.g. first and second pronouns), and sentiment information based on profanity lexicons for this task. Similar features were also exploited for the detection of cyberbullying events and fine-grained text categories related to cyberbullying BIBREF37 , BIBREF40 . More recent studies have demonstrated the added value of combining such content-based features with user-based information, such as including users' activities on a social network (i.e., the number of posts), their age, gender, location, number of friends and followers, and so on BIBREF32 , BIBREF35 , BIBREF41 . Moreover, semantic features have been explored to further improve classification performance of the task. To this end, topic model information BIBREF42 , as well as semantic relations between INLINEFORM1 -grams (according to a Word2Vec model BIBREF43 ) have been integrated.\nAs mentioned earlier, data collection remains a bottleneck in cyberbullying research. Although cyberbullying has been recognised as a serious problem (cf. Section SECREF1 ), real-world examples are often hard to find in public platforms. Naturally, the vast majority of communications do not contain traces of verbal aggression or transgressive behaviour. When constructing a corpus for machine learning purposes, this results in imbalanced datasets, meaning that one class (e.g. cyberbullying posts) is much less represented in the corpus than the other (e.g. non-cyberbullying posts). To tackle this problem, several studies have adopted resampling techniques BIBREF35 , BIBREF41 , BIBREF31 that create synthetic minority class examples or reduce the number of negative class examples (i.e., minority class oversampling and majority class undersampling BIBREF44 ).\nTable TABREF9 presents a number of recent studies on cyberbullying detection, providing insight into the state of the art in cyberbullying research and the contribution of the current research to the domain.\nThe studies discussed in this section have demonstrated the feasibility of automatic cyberbullying detection in social media data by making use of a varied set of features. Most of them have, however, focussed on cyberbullying `attacks', or posts written by a bully. Moreover, it is not entirely clear if different forms of cyberbullying have been taken into account (e.g. sexual intimidation or harassment, or psychological threats), in addition to derogatory language or insults.\nIn the research described in this paper, cyberbullying is considered a complex phenomenon consisting of different forms of harmful behaviour online, which are described in more detail in our annotation scheme BIBREF30 . Purposing to facilitate manual monitoring efforts on social networks, we develop a system that automatically detects signals of cyberbullying, including attacks from bullies, as well as victim and bystander reactions. Similarly, BIBREF42 investigated bullying traces posted by different author roles (accuser, bully, reporter, victim). However, they collected tweets by using specific keywords (i.e., bully, bullied and bullying). As a result, their corpus contains many reports or testimonials of a cyberbullying incident (example 1), instead of actual signals that cyberbullying is going on. Moreover, their method implies that cyberbullying-related content devoid of such keywords will not be part of the training corpus.\n`Some tweens got violent on the n train, the one boy got off after blows 2 the chest... Saw him cryin as he walkd away :( bullying not cool' BIBREF42 \nFor this research, English and Dutch social media data were annotated for different forms of cyberbullying, based on the actors involved in a cyberbullying incident. After preliminary experiments for Dutch BIBREF37 , BIBREF40 , we currently explore the viability of detecting cyberbullying-related posts in Dutch and English social media. To this end, binary classification experiments are performed exploiting a rich feature set and optimised hyperparameters.\nfont=footnotesize,sc,justification=centering,labelsep=period\nThe former involves the construction of a classifier based on labeled training data, whereas semi-supervised approaches rely on classifiers that are built from a training corpus containing a small set of labeled and a large set of unlabelled instances (a method that is often used to handle data sparsity).",

Extractive baselines show the best results for KPCrowd and DUC-2001 which is not surprising given that these datasets exhibit the lowest ratio of absent keyphrases.

We therefore see that these models do not generalize well across domains, confirming previous preliminary findings BIBREF2 and exacerbating the need for further research on this topic. Interestingly, CopyNews outperforms the other models on JPTimes and achieves very low scores for KPCrowd and DUC-2001, although all these datasets are from the same domain. This emphasizes the differences that exist between the reader- and editor-assigned gold standard. The score difference may be explained by the ratio of absent keyphrases that differs greatly between the reader-annotated datasets and JPTimes (see Table ), and thus question the use of these rather extractive datasets for evaluating keyphrase generation.\nFinally, we note that the performance of CopyNews on KPTimes is significantly higher than that of CopySci on KP20k, proving that a more uniform and consistent annotation makes it easier to learn a good model.\nWe therefore see that these models do not generalize well across domains, confirming previous preliminary findings and exacerbating the need for further research on this topic.",

        "evidence": "Recent studies in information extraction domain (but also in other natural language processing fields) show that deep learning models produce state-of-the-art results BIBREF0 . Deep architectures employ multiple layers to learn hierarchical representations of the input data. In the last few years, neural networks based on dense vector representations provided the best results in various NLP tasks, including named entities recognition BIBREF1 , semantic role labelling BIBREF2 , question answering BIBREF3 and multitask learning BIBREF4 . The core element of most deep learning solutions is the dense distributed semantic representation of words, often called word embeddings. Distributional vectors follow the distributional hypothesis that words with a similar meaning tend to appear in similar contexts. Word embeddings capture the similarity between words and are often used as the first layer in deep learning models. Two of the most common and very efficient methods to produce word embeddings are Continuous Bag-of-Words (CBOW) and Skip-gram (SG), which produce distributed representations of words in a vector space, grouping them by similarity BIBREF5 , BIBREF6 . With the progress of machine learning techniques, it is possible to train such models on much larger data sets, and these often outperform the simple ones. It is possible to use a set of text documents containing even billions of words as training data. Both architectures (CBOW and SG) describe how the neural network learns the vector word representations for each word. In CBOW architecture the task is predicting the word given its context and in SG the task in predicting the context given the word.\nWe created a new Polish word embeddings models using the KGR10 corpus. We built 16 models of word embeddings using the implementation of CBOW and Skip-gram methods in the FastText tool BIBREF9 . These models are available under an open license in the CLARIN-PL project DSpace repository. The internal encoding solution based on embeddings of n-grams composing each word makes it possible to obtain FastText vector representations, also for words which were not processed during the creation of the model. A vector representation is associated with character n-gram and each word is represented as the sum of its n-gram vector representations. Previous solutions ignored the morphology of words and were assigning a distinct vector to each word. This is a limitation for languages with large vocabularies and many rare words, like Turkish, Finnish or Polish BIBREF9 . Authors observed that using word representations trained with subword information outperformed the plain Skip-gram model and the improvement was most significant for morphologically rich Slavic languages such as Czech (8% reduction of perplexity over SG) and Russian (13% reduction) BIBREF9 . We expected that word embeddings created that way for Polish should also provide such improvements. There were also previous attempts to build KGR10 word vectors with other methods (including FastText), and the results are presented in the article BIBREF8 . We selected the best models from that article – with embedding ID prefix EP (embeddings, previous) in Table TABREF13 – to compare with new models, marked as embedding ID prefix EC in Table TABREF13 ).\nIn CBOW architecture the task is predicting the word given its context and in SG the task in predicting the context given the word.\nWe built 16 models of word embeddings using the implementation of CBOW and Skip-gram methods in the FastText tool BIBREF9 .",

Sugar also comes in many different types - cane sugar, beet sugar, raw sugar, white refined sugar, brown sugar, caster sugar, sugar lumps, icing sugar (also known as milled sugar), sugar syrup, invert sugar, and a plethora of sugar substitutes including smart sugar which is essentially a blend of pure sugar and a sugar substitute. Each of these product types is designed to meet the needs of specific market segments. Invert sugar and sugar syrups, for example, are marketed to food manufacturers where they are used in the production of conserves, chocolate, and baked goods. Sugars marketed to consumers appeal to different usage segments – refined sugar is primarily for use on the table, while caster sugar and icing sugar are primarily designed for use in home-baked goods.",

The process of joining the alliance is governed by Article 10 of the North Atlantic Treaty, which allows for the invitation of \"other European States\" only and by subsequent agreements. Countries wishing to join must meet certain requirements and complete a multi-step process involving political dialog and military integration. The accession process is overseen by the North Atlantic Council, NATO's governing body. NATO was formed in 1949 with twelve founding members and has added new members nine times. The first additions were Greece and Turkey in 1952. In May 1955, West Germany joined NATO, which was one of the conditions agreed to as part of the end of the country's occupation by France, the United Kingdom, and the United States, prompting the Soviet Union to form their own collective security alliance (commonly called the Warsaw Pact) later that month. Following the end of the Franco regime, newly-democratic Spain chose to join NATO in 1982.\n\nIn 1990, the negotiators reached an agreement that a reunified Germany would be in NATO under West Germany's existing membership. The dissolution of the Soviet Union in 1991 led many former Warsaw Pact and post-Soviet states to initiate discussions about joining NATO. Poland, Hungary, and the Czech Republic became NATO members in 1999, amid much debate within NATO itself and Russian opposition. NATO then formalized the process of joining the organization with \"Membership Action Plans\", which aided the accession of seven Central and Eastern Europe countries shortly before the 2004 Istanbul summit: Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, and Slovenia. Two countries on the Adriatic Sea—Albania and Croatia—joined on 1 April 2009 before the 2009 Strasbourg–Kehl summit. The next member states to join NATO were Montenegro on 5 June 2017, North Macedonia on 27 March 2020 and Finland on 4 April 2023.\n\nRussia's invasion of Ukraine prompted Finland and Sweden to apply for NATO membership in May 2022, and the ratification process for Sweden is in progress. Finland officially joined on 4 April 2023. Ukraine applied for NATO membership in September 2022 after Russia claimed to annex part of its territory. Two other states have formally informed NATO of their membership aspirations: Bosnia and Herzegovina and Georgia. Kosovo also aspires to join NATO. Joining the alliance is a debate topic in several other European countries outside the alliance, including Austria, Ireland, Malta, Moldova, and Serbia.",

        "question": "What Conversational Systems do the authors focus on in this paper?",
        "answer": "Natural Dialogue Systems.",
        "evidence": "Back to 42 BC, the philosopher Cicero has raised the issue that although there were many Oratory classes, there were none for Conversational skills BIBREF0 . He highlighted how important they were not only for politics, but also for educational purpose. Among other conversational norms, he claimed that people should be able to know when to talk in a conversation, what to talk depending on the subject of the conversation, and that they should not talk about themselves.\nNorms such as these may become social conventions and are not learnt at home or at school. Social conventions are dynamic and may change according to context, culture and language. In online communication, new commonsense practices are evolved faster and accepted as a norm BIBREF1 , BIBREF2 . There is not a discipline for that on elementary or high schools and there are few linguistics researchers doing research on this field.\nOn the other hand, within the Artificial Intelligence area, some Conversational Systems have been created in the past decades since the test proposed by Alan Turing in 1950. The test consists of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from that of a human BIBREF3 . Turing proposed that a human evaluator would judge natural language conversations between a human and a machine that is designed to generate human-like responses. Since then, many systems have been created to pass the Turing's test. Some of them have won prizes, some not BIBREF4 . Although in this paper we do not focus on creating a solution that is able to build conversational systems that pass the Turing's test, we focus on NDS. From BIBREF5 , \"NDS are systems that try to improve usability and user satisfaction by imitating human behavior\". We refer to Conversational Systems as NDS, where the dialogues are expressed as natural language texts, either from artificial intelligent agents (a.k.a. bots) or from humans.\nThat said, the current popular name to systems that have the ability to make a conversation with humans using natural language is Chatbot. Chatbots are typically used in conversational systems for various practical purposes, including customer service or information acquisition. Chatbots are becoming more widely used by social media software vendors. For example, Facebook recently announced that it would make Facebook Messenger (its 900-million-user messaging app by 2016), into a full-fledged platform that allows businesses to communicate with users via chatbots. Google is also building a new mobile-messaging service that uses artificial intelligence know-how and chatbot technology. In addition, according to the Wall Street Journal, there are more than 2 billion users of mobile apps. Still, people can be reluctant to install apps. So it is believed that social messaging can be a platform and chatbots may provide a new conversational interface for interacting with online services, as chatbots are easier to build and deploy than apps BIBREF6 .\nChina seems to be the place where chatbots adoption and use is most advanced today. For example, China's popular WeChat messaging platform can take payments, scan QR codes, and integrate chatbot systems. WeChat integrates e-mail, chat, videocalls and sharing of large multimedia files. Users can book flights or hotels using a mixed, multimedia interaction with active bots. WeChat was first released in 2011 by Tecent, a Chinese online-gaming and social-media firm, and today more than 700 million people use it, being one of the most popular messaging apps in the world (The Economist 2016). WeChat has a mixture of real-live customer service agents and automated replies (Olson 2016).\nStill, current existing chatbot engines do not properly handle a group chat with many users and many chatbots. This makes the chatbots considerably less social, which is a problem since there is a strong demand of having social chatbots that are able to provide different kinds of services, from traveling packages to finance advisors. This happens because there is a lack of methods and tools to design and engineer the coordination and mediation among chatbots and humans, as we present in Sections 2 and 3. In this paper, we refer to conversational systems that are able to interact with one or more people or chatbots in a multi-party chat as MPCS. Altogether, this paper is not meant to advance the state of the art on the norms for MPCS. Instead, the main contributions of this paper are threefold:\nWe then present some discussion and future work in the last section.\nAlthough in this paper we do not focus on creating a solution that is able to build conversational systems that pass the Turing’s test, we focus on Natural Dialogue Systems (NDS).",

Preparation ensures that the appropriate texture has been introduced to the top layer of the concrete and helps the epoxy to bond with the concrete better. This ensures long-lasting results. All of these different methods of preparing concrete vary in terms of the level of difficulty as well as the efficacy produced. Following are the most popular techniques:\n\n1. Acid Etching: This is the most DIY friendly option & involves the use of an acid that is allowed to rest for some time over the concrete surface and then cleaned after a few minutes. This is also the quickest among all the techniques. The downside however is that the etching process may not produce the best concrete texture that ensures a long-lasting bond. \n2. Walk-behind Concrete Diamond grinder: This produces one of the best results when compared to the other techniques. It involves the use of a walk behind concrete grinder which has been fitted with a diamond grinding attachment. The disadvantage of this method is that it requires specialized equipment which may not be readily available & is a lot more time consuming compared to Acid etching.\n3.

        "question": "What was common to both models?",
        "answer": "Common to both models was the decision to alternate between training the generator for 50 steps and the discriminator for 2000 steps.",
        "evidence": "In seeking to answer the question of whether the occupancy rate of a listing could be extracted from the listing’s summary, we ran a number of experiments on our first model. Two parameterizations which we present here are (1) whether the word vectors used in the embedding layer are trained on our corpus or come pretrained from Wikipedia and Gigaword and (2) whether ensembling or the final hidden state in isolation are used to make a prediction for the sequence. Common to all experiments was our decision to use an Adam optimizer, 16 LSTM units, 50-dimensional GloVe vectors, and a 70-30 split in train and test data.\nOver ten epochs, the model parameterization which performs the best uses GloVe vectors trained on a corpus consisting of all listing descriptions and ensembling to make its class prediction. As a result, our findings are well in-line with those presented by Radford et. al who underscore the importance of training word embeddings on a data-specific corpus for best results on generative tasks [9].\nThat said, these results, though they do show a marginal increase in dev accuracy and a decrease in CE loss, suggest that perhaps listing description is not too predictive of occupancy rate given our parameterizations. While the listing description is surely an influential metric in determining the quality of a listing, other factors such as location, amenities, and home type might play a larger role in the consumer's decision. We were hopeful that these factors would be represented in the price per bedroom of the listing – our control variable – but the relationship may not have been strong enough.\nHowever, should a strong relationship actually exist and there be instead a problem with our method, there are a few possibilities of what went wrong. We assumed that listings with similar occupancy rates would have similar listing descriptions regardless of price, which is not necessarily a strong assumption. This is coupled with an unexpected sparseness of clean data. With over 40,000 listings, we did not expect to see such poor attention to orthography in what are essentially public advertisements of the properties. In this way, our decision to use a window size of 5, a minimum occurrence count of 2, and a dimensionality of 50 when training our GloVe vectors was ad hoc.\nSeeking to create a model which could generate and discriminate a “high-occupancy listing description”, we wanted to evaluate the capabilities of a generative adversarial network trained on either the standard binary cross-entropy loss or the DMK loss proposed above. Common to both models was the decision to alternate between training the generator for 50 steps and the discriminator for 2000 steps. We leave further tuning of the models to future research as each occasionally falls into unideal local optima within 20 iterations. One potential culprit is the step imbalance between generator and discriminator – should either learn at a much faster rate than the other, one component is liable to be “defeated\" and cease to learn the training data.\nQualitatively the network trained on the DMK loss shows great promise. With respect to the two experiments presented here, we have shown that it is possible to introduce a measure of suggestion in the text produced by the generator. While this model is also subject to a rapid deadlock between generator and discriminator, it is interesting to see how the introduction of keywords is gradual and affects the proximal tokens included in the output. This behavior was made possible by paying close attention to the hyperparameter $\\gamma $ , the weight given to the dot product attention term of the DMK loss. After manual tuning, we settle on $\\gamma =0.00045$ for this weight. Below, we illustrate model outputs using different values of Gamma. As is apparent, for a hyper-parameter value less than roughly $\\gamma = 0.0004$ , the model tends to ignore the importance of the keyword weights. Conversely, with a $\\gamma $ value higher than $0.0005$ , the model tends towards overweighting the representation of the keywords in the model output.\nSeeking to create a model which could generate and discriminate a high-occupancy listing description, we wanted to evaluate the capabilities of a generative adversarial network trained on either the standard binary cross-entropy loss or the DMK loss proposed above.

In addition, we find that evaluating generated samples by comparing it with a set of randomly selected samples or using sample-level skill rating performs almost equally well. This is not surprising as the employed skill rating is able to handle the inherent variance of players (i.e. NLG models). As this variance does not exist when we regard a sample as a model which always generates the same sample.\nResults are shown in Table 2.

        "evidence": "Both neural and statistical machine translation approaches are highly reliant on the availability of large amounts of data and are known to perform poorly in low resource settings. Recent crowd-sourcing efforts and workshops on machine translation have resulted in small amounts of parallel texts for building viable machine translation systems for low-resource pairs BIBREF0 . But, they have been shown to suffer from low accuracy (incorrect translation) and low coverage (high out-of-vocabulary rates), due to insufficient training data. In this project, we try to address the high OOV rates in low-resource machine translation systems by leveraging the increasing amount of multilingual content available on the Internet for enriching the bilingual lexicon.\nComparable corpora such as Wikipedia, are collections of topic-aligned but non-sentence-aligned multilingual documents which are rich resources for extracting parallel sentences from. For example, Figure FIGREF1 shows that there are equivalent sentences on the page about Donald Trump in Tamil and English, and the phrase alignment for an example sentence is shown in Table TABREF4 .\nTable TABREF2 shows that there are at least tens of thousands of bilingual articles on Wikipedia which could potentially have at least as many parallel sentences that could be mined to address the scarcity of parallel sentences as indicated in column 2 which shows the number of sentence-pairs in the largest available bilingual corpora for xx-en. As shown by BIBREF1 ( BIBREF1 ), the illustrated data sparsity can be addressed by extending the scarce parallel sentence-pairs with those automatically extracted from Wikipedia and thereby improving the performance of statistical machine translation systems.\nIn this paper, we will propose a neural approach to parallel sentence extraction and compare the BLEU scores of machine translation systems with and without the use of the extracted sentence pairs to justify the effectiveness of this method. Compared to previous approaches which require specialized meta-data from document structure or significant amount of hand-engineered features, the neural model for extracting parallel sentences is learned end-to-end using only a small bootstrap set of parallel sentence pairs.\nCompared to previous approaches which require specialized meta-data from document structure or significant amount of hand-engineered features, the neural model for extracting parallel sentences is learned end-to-end using only a small bootstrap set of parallel sentence pairs.",

Examining metadata is a good way to check a collection's balance and representativeness. Are sources disproportionately of one form? Is the collection missing a specific time window? This type of curation can be extremely time consuming as it may require expert labeling, but it often leads to the most compelling results. Sometimes metadata are also used as target labels to develop machine learning models. But using them as a “ground truth” requires caution. Labels sometimes mean something different than we expect.

For the lexicon, we used NileULex BIBREF26, which is an Arabic polarity lexicon containing 3,279 MSA and 2,674 Egyptian terms, out of which 4,256 are negative and 1,697 are positive. We used the counts of terms with positive polarity and terms with negative polarity in tweets as features.\nWe experimented with various static embeddings that were pre-trained on different corpora with different vector dimensionality. We compared pre-trained embeddings to embeddings that were trained on our dataset. For pre-trained embeddings, we used: fastText Egyptian Arabic pre-trained embeddings BIBREF27 with vector dimensionality of 300; AraVec skip-gram embeddings BIBREF28, trained on 66.9M Arabic tweets with 100-dimensional vectors; and Mazajak skip-gram embeddings BIBREF29, trained on 250M Arabic tweets with 300-dimensional vectors.\nSentence embeddings were calculated by taking the mean of the embeddings of their tokens. The importance of testing a character level n-gram model like fastText lies in the agglutinative nature of the Arabic language. We trained a new fastText text classification model BIBREF30 on our dataset with vectors of 40 dimensions, 0.5 learning rate, 2$-$10 character n-grams as features, for 30 epochs. These hyper-parameters were tuned using a 5-fold cross-validated grid-search.\nWe also experimented with pre-trained contextualized embeddings with fine-tuning for down-stream tasks. Recently, deep contextualized language models such as BERT (Bidirectional Encoder Representations from Transformers) BIBREF31, UMLFIT BIBREF32, and OpenAI GPT BIBREF33, to name but a few, have achieved ground-breaking results in many NLP classification and language understanding tasks. In this paper, we used BERTbase-multilingual (hereafter as simply BERT) fine-tuning method to classify Arabic offensive language on Twitter as it eliminates the need of heavily engineered task-specific architectures. Although Robustly Optimized BERT (RoBERTa) embeddings perform better than (BERTlarge) on GLUE BIBREF34, RACE BIBREF35, and SQuAD BIBREF36 tasks, pre-trained multilingual RoBERTa models are not available. BERT is pre-trained on Wikipedia text from 104 languages and comes with hundreds of millions of parameters. It contains an encoder with 12 Transformer blocks, hidden size of 768, and 12 self-attention heads. Though the training data for the BERT embeddings don't match our genre, these embedding use BP sub-word segments. Following devlin-2019-bert, the classification consists of introducing a dense layer over the final hidden state $h$ corresponding to first token of the sequence, [CLS], adding a softmax activation on the top of BERT to predict the probability of the $l$ label:\n\n\nwhere $W$ is the task-specific weight matrix. During fine-tuning, all BERT parameters together with $W$ are optimized end-to-end to maximize the log-probability of the correct labels.\nFor the lexicon, we used NileULex (El-Beltagy, 2016), which is an Arabic polarity lexicon containing 3,279 MSA and 2,674 Egyptian terms, out of which 4,256 are negative and 1,697 are positive.",

Each section covers researchers and engineers working on different challenges in the alignment of artificial intelligence with human values.\n\nProphecy\nIn the first section, Christian interweaves discussions of the history of artificial intelligence research, particularly the machine learning approach of artificial neural networks such as the Perceptron and AlexNet, with examples of how AI systems can have unintended behavior. He tells the story of Julia Angwin, a journalist whose ProPublica investigation of the COMPAS algorithm, a tool for predicting recidivism among criminal defendants, led to widespread criticism of its accuracy and bias towards certain demographics. One of AI's main alignment challenges is its black box nature (inputs and outputs are identifiable but the transformation process in between is undetermined). The lack of transparency makes it difficult to know where the system is going right and where it is going wrong.\n\nAgency\nIn the second section, Christian similarly interweaves the history of the psychological study of reward, such as behaviorism and dopamine, with the computer science of reinforcement learning, in which AI systems need to develop policy (\"what to do\") in the face of a value function (\"what rewards or punishment to expect\"). He calls the DeepMind AlphaGo and AlphaZero systems \"perhaps the single most impressive achievement in automated curriculum design.\" He also highlights the importance of curiosity, in which reinforcement learners are intrinsically motivated to explore their environment, rather than exclusively seeking the external reward.\n\nNormativity\nThe third section covers training AI through the imitation of human or machine behavior, as well as philosophical debates such as between possibilism and actualism that imply different ideal behavior for AI systems. Of particular importance is inverse reinforcement learning, a broad approach for machines to learn the objective function of a human or another agent. Christian discusses the normative challenges associated with effective altruism and existential risk, including the work of philosophers Toby Ord and William MacAskill who are trying to devise human and machine strategies for navigating the alignment problem as effectively as possible.",

        "question": "Given these paragraphs about Large language models, how many words did the BookCorpus have when it was used to train the first model in OpenAI's GPT series trained in 2018?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

        "question": "Could data biases lead to spurious results and limit justification for generalization?",
        "answer": "Yes.",
        "evidence": "Many scholars in the humanities and the social sciences work with sources that are not available in digital form, and indeed may never be digitized. Others work with both analogue and digitized materials, and the increasing digitization of archives has opened opportunities to study these archives in new ways. We can go to the canonical archive or open up something that nobody has studied before. For example, we might focus on major historical moments (French Revolution, post-Milosevic Serbia) or critical epochs (Britain entering the Victorian era, the transition from Latin to proto-Romance). Or, we could look for records of how people conducted science, wrote and consumed literature, and worked out their philosophies.\nA growing number of researchers work with born-digital sources or data. Born-digital data, e.g., from social media, generally do not involve direct elicitation from participants and therefore enable unobtrusive measurements BIBREF5 , BIBREF6 . In contrast, methods like surveys sometimes elicit altered responses from participants, who might adapt their responses to what they think is expected. Moreover, born-digital data is often massive, enabling large-scale studies of language and behavior in a variety of social contexts.\nStill, many scholars in the social sciences and humanities work with multiple data sources. The variety of sources typically used means that more than one data collection method is often required. For example, a project examining coverage of a UK General Election, could draw data from traditional media, web archives, Twitter and Facebook, campaign manifestos, etc. and might combine textual analysis of these materials with surveys, laboratory experiments, or field observations offline. In contrast, many computational studies based on born-digital data have focused on one specific source, such as Twitter.\nThe use of born-digital data raises ethical concerns. Although early studies often treated privacy as a binary construct, many now acknowledge its complexity BIBREF7 . Conversations on private matters can be posted online, visible for all, but social norms regarding what should be considered public information may differ from the data's explicit visibility settings. Often no informed consent has been obtained, raising concerns and challenges regarding publishing content and potentially harmful secondary uses BIBREF8 , BIBREF4 .\nRecently, concerns about potential harms stemming from secondary uses have led a number of digital service providers to restrict access to born-digital data. Facebook and Twitter, for example, have reduced or eliminated public access to their application programming interfaces (APIs) and expressed hesitation about allowing academic researchers to use data from their platforms to examine certain sensitive or controversial topics. Despite the seeming abundance of born-digital data, we therefore cannot take its availability for granted.\nWorking with data that someone else has acquired presents additional problems related to provenance and contextualisation. It may not always be possible to determine the criteria applied during the creation process. For example, why were certain newspapers digitized but not others, and what does this say about the collection? Similar questions arise with the use of born-digital data. For instance, when using the Internet Archive’s Wayback Machine to gather data from archived web pages, we need to consider what pages were captured, which are likely missing, and why.\nWe must often repurpose born-digital data (e.g., Twitter was not designed to measure public opinion), but data biases may lead to spurious results and limit justification for generalization. In particular, data collected via black box APIs designed for commercial, not research, purposes are likely to introduce biases into the inferences we draw, and the closed nature of these APIs means we rarely know what biases are introduced, let alone how severely they might impact our research BIBREF10 . These, however, are not new problems. Historians, for example, have always understood that their sources were produced within particular contexts and for particular purposes, which are not always apparent to us.\nNon-representative data can still be useful for making comparisons within a sample. In the introductory example on hate speech BIBREF0 , the Reddit forums do not present a comprehensive or balanced picture of hate speech: the writing is almost exclusively in English, the targets of hate speech are mainly restricted (e.g., to black people, or women), and the population of writers is shaped by Reddit's demographics, which skew towards young white men. These biases limit the generalizability of the findings, which cannot be extrapolated to other languages, other types of hate speech, and other demographic groups. However, because the findings are based on measurements on the same sort of hate speech and the same population of writers, as long as the collected data are representative of this specific population, these biases do not pose an intractable validity problem if claims are properly restricted.\nThe size of many newly available datasets is one of their most appealing characteristics. Bigger datasets often make statistics more robust. The size needed for a computational text analysis depends on the research goal: When it involves studying rare events, bigger datasets are needed. However, larger is not always better. Some very large archives are “secretly” collections of multiple and distinct processes that no in-field scholar would consider related. For example, Google Books is frequently used to study cultural patterns, but the over-representation of scientific articles in Google books can be problematic BIBREF11 . Even very large born-digital datasets usually cover limited timespans compared to, e.g., the Gutenberg archive of British novels.\nThis stage of the research also raises important questions about fairness. Are marginalized groups, for example, represented in the tweets we have collected? If not, what types of biases might result from analyses relying on those tweets?\nLocal experts and “informants” can help navigate the data. They can help understand the role an archive plays in the time and place. They might tell us: Is this the central archive, or a peripheral one? What makes it unusual? Or they might tell us how certain underrepresented communities use a social media platform and advise us on strategies for ensuring our data collection includes their perspectives.\nHowever, when it is practically infeasible to navigate the data in this way—for instance, when we cannot determine what is missing from Twitter's Streaming API or what webpages are left out of the Internet Archive—we should be open about the limitations of our analyses, acknowledging the flaws in our data and drawing cautious and reasonable conclusions from them. In all cases, we should report the choices we have made when creating or re-using any dataset.\nWe must often repurpose born-digital data (e.g., Twitter was not designed to measure public opinion), but data biases may lead to spurious results and limit justification for generalization.2",

        "evidence": "Sarcasm, a creative device used to communicate an intended meaning that is actually the opposite of its literal meaning, is notoriously difficult to convey and interpret through text, in part because doing so relies heavily upon shared contextual understandings that can be marked more easily by altered prosody (e.g., emphasis upon certain words) or non-verbal signals (e.g., rolling one's eyes). It is a complex process even for humans, and in fact an inability to detect sarcasm has been linked with a number of neurocognitive disorders, including dementia BIBREF0 . It is similarly a challenging open task in natural language processing, and has direct implications to a number of other critical application areas, such as sentiment analysis.\nMost research on automatic sarcasm detection to date has focused on the Twitter domain, which boasts an ample source of publicly-available data, some of which is already self-labeled by users for the presence of sarcasm (e.g., with #sarcasm). However, Twitter is highly informal, space-restricted, and subject to frequent topic fluctuations from one post to the next due to the ebb and flow of current events—in short, it is not broadly representative of most text domains. Thus, sarcasm detectors trained using features designed for maximum Twitter performance are not necessarily transferable to other domains. Despite this, it is desirable to develop approaches that can harness the more generalizable information present in the abundance of Twitter data.\nIn this work, we develop a set of domain-independent features for sarcasm detection and show that the features generally perform well across text domains. Further, we validate that domain adaptation can be applied to sarcasm detection to leverage patterns in out-of-domain training data, even when results from training only on that source domain data are extremely bad (far below baseline results), to improve over training on only the target data or over training on the simply combined dataset. Finally, we make a new dataset of sarcastic and non-sarcastic tweets available online as a resource to other researchers.\nIn this work, we develop a set of domain-independent features for sarcasm detection and show that the features generally perform well across text domains.",

This might be due to maintenance activities with employees working on a section of the power grid, or to prevent issues in inclimate weather, such as preventing wildfire ignition in high-wind events. \n- Weather-caused issues: high wind or ice-storms can sometimes snap power lines or cause tree limbs to fall. \n\nCheck with your utility provider to stay up to date on any outage you are experiencing.

These approaches incorporate information about the sequential position of elements differently.\nRecurrent neural networks (RNNs) typically compute a hidden state $h_t$ , as a function of their input at time $t$ and a previous hidden state $h_{t-1}$ , capturing relative and absolute positions along the time dimension directly through their sequential structure. Non-recurrent models do not necessarily consider input elements sequentially and may hence require explicitly encoding position information to be able to use sequence order.\nOne common approach is to use position encodings which are combined with input elements to expose position information to the model. These position encodings can be a deterministic function of position BIBREF8 , BIBREF3 or learned representations. Convolutional neural networks inherently capture relative positions within the kernel size of each convolution. They have been shown to still benefit from position encodings BIBREF1 , however.\nFor the Transformer, which employs neither convolution nor recurrence, incorporating explicit representations of position information is an especially important consideration since the model is otherwise entirely invariant to sequence ordering. Attention-based models have therefore used position encodings or biased attention weights based on distance BIBREF9 .\nIn this work we present an efficient way of incorporating relative position representations in the self-attention mechanism of the Transformer. Even when entirely replacing its absolute position encodings, we demonstrate significant improvements in translation quality on two machine translation tasks.\nOur approach can be cast as a special case of extending the self-attention mechanism of the Transformer to considering arbitrary relations between any two elements of the input, a direction we plan to explore in future work on modeling labeled, directed graphs.\nIn this work we present an efficient way of incorporating relative position representations in the self-attention mechanism of the Transformer.",

The main research group in machine translation was formed in 1958, at the Circle for Young Linguists in Zagreb, initiated by a young linguist Bulcsu Laszlo, who graduated in Russian language, Southern Slavic languages and English language and literature at the University of Zagreb in 1952. The majority of the group members came from different departments of the Faculty of Humanities and Social Sciences of the University of Zagreb, with several individuals from other institutions. The members from the Faculty of Humanities and Social Sciences were: Svetozar Petrović (Department of Comparative Literature), Stjepan Babić (Department of Serbo-Croatian Language and Literature), Krunoslav Pranjić (Department of Serbo-Croatian Language and Literature), Željko Bujas (Department of English Language and Literature), Malik Mulić (Department of Russian Language and Literature) and Bulcsu Laszlo (Department of Comparative Slavistics). The members of the research group from outside the Faculty of Humanities and Social Sciences were: Božidar Finka (Institute for Language of the Yugoslav Academy of Sciences and Arts), Vladimir Vranić (Center for Numerical Research of the Yugoslav Academy of Sciences and Arts), Vladimir Matković (Institute for Telecommunications), Vladimir Muljević (Institute for Regulatory and Signal Devices) BIBREF10.\nLaszlo and Petrović BIBREF11 also commented on the state of the art of the time, noting the USA prototype efforts from 1954 and the publication of a collection of research papers in 1955 as well as the USSR efforts starting from 1955 and the UK prototype from 1956. They do not detail or cite the articles they mention. However, the fact that they referred to them in a text published in 1959 (probably prepared for publishing in 1958, based on BIBREF11, where Laszlo and Petrović described that the group had started its work in 1958) leads us to the conclusion that the poorly funded Croatian research was lagging only a couple of years behind the research of the superpowers (which invested heavily in this effort). Another interesting moment, which they delineated in BIBREF11, is that the group soon discovered that some experimental work had already been done in 1957 at the Institute of Telecommunications (today a part of the Faculty of Electrical Engineering and Computing at the University of Zagreb) by Vladimir Matković. Because of this, they decided to include him in the research group of the Faculty of Humanities and Social Sciences at the University of Zagreb. The work done by Matković was documented in his doctoral dissertation but remained unpublished until 1959.\nThe Russian machine translation pioneer Andreev expressed hope that the Yugoslav (Croatian) research group could create a prototype, but sadly, due to the lack of federal funding, this never happened BIBREF10. Unlike their colleagues in the USA and the USSR, Laszlo’s group had to manage without an actual computer (which is painfully obvious in BIBREF12), and the results remained mainly theoretical. Appealing probably to the political circles of the time, Laszlo and Petrović note that, although it sounds strange, research in computational linguistics is mainly a top-priority military effort in other countries BIBREF11. There is a quote from BIBREF10 which perhaps best delineates the optimism and energy that the researchers in Zagreb had:\n\"[...] The process of translation has to mechanicalized as soon as possible, and this is only possible if a competent, fast and inexhaustible machine which could inherit the translation task is created, even if just schematic. The machine needs to think for us. If machines help humans in physical tasks, why would they not help them in mental tasks with their mechanical memory and automated logic\" (p. 118).\nPranji´c [22] analyses and extrapolates five basic ideas in the Soviet Machine Translation program, which were the basis for the Croatian approach: 1. Separation of the dictionary from the MT algorithm 2. Separation of the understanding and generation modules of the MT algorithms 3. All words need to be lemmatized 4.

Modern boomerangs used for sport may be made from plywood or plastics such as ABS, polypropylene, phenolic paper, or carbon fibre-reinforced plastics.\n\nBoomerangs come in many shapes and sizes depending on their geographic or tribal origins and intended function. Many people think only of the traditional Australian type, although today there are many types of more easily usable boomerangs, such as the cross-stick, the pinwheel, the tumble-stick, the Boomabird, and many other less common types.\n\nAn important distinction should be made between returning boomerangs and non-returning boomerangs:\n\nReturning boomerangs fly, and are examples of the earliest heavier-than-air human-made flight. A returning boomerang has two or more aerofoil section wings arranged so that when spinning they create unbalanced aerodynamic forces that curve its path into an ellipse, returning to its point of origin when thrown correctly. Their typical L-shape makes them the most recognisable form of boomerang. Although used primarily for leisure or recreation, returning boomerangs are also used to decoy birds of prey, thrown above the long grass to frighten game birds into flight and into waiting nets. Non-traditional, modern, competition boomerangs come in many shapes, sizes and materials.\nNon-returning boomerangs, throwing sticks, valari, or kylies, are primarily used as weapons.

        "question": "Who is credited with the recognition of electromagnetism?",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word.",

Peter Gammons noted in 2022 that when he talked to Altuve in 2020 about how players, coaches, and members in the organization believed that Altuve did not participate in the stealing, Altuve declined to talk about it. He stated that it would be a \"betrayal of my teammates\" to discuss the matter and asked that Gammons not write about it. Despite this, many Astros players have defended Altuve in particular of any wrongdoing. Carlos Correa, in an interview with Ken Rosenthal, stated of Altuve's role in the scandal: \"The few times that the trash can was banged was without his consent, and he would go inside the clubhouse and inside the dugout to whoever was banging the trash can and he would get pissed.

        "answer": "In many cases, the identification of the referent of the prounoun in a Winograd schema is critical for finding the correct translation of that pronoun in a different language.",
        "evidence": "In many cases, the identification of the referent of the prounoun in a Winograd schema is critical for finding the correct translation of that pronoun in a different language. Therefore, Winograd schemas can be used as a very difficult challenge for the depth of understanding achieved by a machine translation program.\nThe third person plural pronoun `they' has no gender in English and most other languages (unlike the third person singular pronouns `he', `she', and `it'). However Romance languages such as French, Italian, and Spanish, and Semitic languages such as Hebrew and Arabic distinguish between the masculine and the feminine third-person plural pronouns, at least in some grammatical cases. For instance in French, the masculine pronoun is `ils'; the feminine pronoun is `elles'. In all of these cases, the masculine pronoun is standardly used for groups of mixed or unknown gender.\nIn order to correctly translate a sentence in English containing the word `they' into one of these languages, it is necessary to determine whether or not the referent is a group of females. If it is, then the translation must be the feminine pronoun; otherwise, it must be the masculine pronoun. Therefore, if one can create a Winograd schema in English where the ambiguous pronoun is `they' and the correct referent for one element is a collection of men and for the other is a collection of women, then to translate both elements correctly requires solving the Winograd schema.\nAs an example, consider the Winograd schema:\nIf these sentences are translated into French, then `they' in the first sentence should be translated `elles', as referring to Jane and Susan, and `they' in the second sentence should be translated `ils', as referring to Fred and George.\nA number of the Winograd schemas already published can be “converted” quite easily to this form. Indeed, the above example was constructed in this way; the original form was “Jane knocked on Susan's door, but she did not [answer/get an answer].” Of the 144 schemas in the collection at http://www.cs.nyu.edu/faculty/davise/papers/WinogradSchemas/WSCollection.html there are 33 that can plausibly be translated this way. (#'s 3, 4, 12, 15, 17, 18, 23, 25, 26, 27, 42, 43, 44, 45, 46, 57, 58, 60, 69, 70, 71, 77, 78, 79, 86, 97, 98, 106, 111, 114, 127, 132, 144) — essentially any schema that involves two people as possible referents where the content of the sentences makes sense as applied to groups of people rather than individuals.\nA similar device, in the opposite direction, relies on the fact that French does not distinguish between the possessive pronouns `his' and `her'. The pronouns `son' and `sa' are gendered, but the gender agrees with the possession, not the possessor. Therefore a Winograd schema that relies on finding a referent for a possessive pronoun can be turned into a hard pair of French-to-English translation problems by making one possible referent male and the other one female. For example, schema #124 in the online collection reads “The man lifted the boy onto his [bunk bed/shoulders].” Changing the boy to a girl and translating into French gives “L'homme leva la fille sur [ses épaules/son lit superposé]”. In the first sentence “ses” is translated “his”, in the second “son” is translated “her”. The eleven Winograd schemas #'s 112, 117, 118, 119, 124, 125, 127, 129, 130, 131, and 143 can be converted this way.\nCare must be taken to avoid relying on, or seeming to rely on, objectionable stereotypes about men and women. One mechanism that can sometimes be used is to include a potentially problematic sentence in both directions. For instance, schema 23 from the WSC collection can be translated into both “The girls were bullying the boys so we [punished/rescued] them” and “The boys were bullying the girls, so we [punished/rescued] them,” thus avoiding any presupposition of whether girls are more likely to bully boys or vice versa.\nA historical note: Winograd schemas were named after Terry Winograd because of a well-known example in his doctoral thesis (Winograd 1970). In his thesis, this example followed the above form, and the importance of the example was justified in terms of machine translation. Winograd's original schema was: “The city councilmen refused to give the women a permit for a demonstration because they [feared/advocated] violence\", and Winograd explained that, in the sentence with `feared', `they' would refer to the councilmen and would be translated as `ils' in French, whereas in the sentence with `advocated', `they' would refer to the women and would be translated as `elles'. In the later versions of the thesis, published as (Winograd 1972), he changed `women' to `demonstrators'; this made the disambiguation clearer, but lost the point about translation.\nIn many cases, the identification of the referent of the prounoun in a Winograd schema is critical for finding the correct translation of that pronoun in a different language. Therefore, Winograd schemas can be used as a very difficult challenge for the depth of understanding achieved by a machine translation program.",

        "evidence": "Given the large collections of unstructured and semi-structured data available on the web, there is a crucial need to enable quick and efficient access to the knowledge content within them. Traditionally, the field of information extraction has focused on extracting such knowledge from unstructured text documents, such as job postings, scientific papers, news articles, and emails. However, the content on the web increasingly contains more varied types of data, including semi-structured web pages, tables that do not adhere to any schema, photographs, videos, and audio. Given a query by a user, the appropriate information may appear in any of these different modes, and thus there's a crucial need for methods to construct knowledge bases from different types of data, and more importantly, combine the evidence in order to extract the correct answer.\nMotivated by this goal, we introduce the task of multimodal attribute extraction. Provided contextual information about an entity, in the form of any of the modes described above, along with an attribute query, the goal is to extract the corresponding value for that attribute. While attribute extraction on the domain of text has been well-studied BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , to our knowledge this is the first time attribute extraction using a combination of multiple modes of data has been considered. This introduces additional challenges to the problem, since a multimodal attribute extractor needs to be able to return values provided any kind of evidence, whereas modern attribute extractors treat attribute extraction as a tagging problem and thus only work when attributes occur as a substring of text.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API. The collection of items is diverse and includes categories such as electronic products, jewelry, clothing, vehicles, and real estate. For each item, we provide a textual product description, collection of images, and open-schema table of attribute-value pairs (see Figure 1 for an example). The provided attribute-value pairs only provide a very weak source of supervision; where the value might appear in the context is not known, and further, it is not even guaranteed that the value can be extracted from the provided evidence. In all, there are over 4 million images and 7.6 million attribute-value pairs. By releasing such a large dataset, we hope to drive progress on this task similar to how the Penn Treebank BIBREF5 , SQuAD BIBREF6 , and Imagenet BIBREF7 have driven progress on syntactic parsing, question answering, and object recognition, respectively.\nTo asses the difficulty of the task and the dataset, we first conduct a human evaluation study using Mechanical Turk that demonstrates that all available modes of information are useful for detecting values. We also train and provide results for a variety of machine learning models on the dataset. We observe that a simple most-common value classifier, which always predicts the most-common value for a given attribute, provides a very difficult baseline for more complicated models to beat (33% accuracy). In our current experiments, we are unable to train an image-only classifier that can outperform this simple model, despite using modern neural architectures such as VGG-16 BIBREF8 and Google's Inception-v3 BIBREF9 . However, we are able to obtain significantly better performance using a text-only classifier (59% accuracy). We hope to improve and obtain more accurate models in further research.\nTo asses the difficulty of the task and the dataset, we first conduct a human evaluation study using Mechanical Turk that demonstrates that all available modes of information are useful for detecting values.",

Quantitative easing is a novel form of monetary policy that came into wide application after the financial crisis of 2007-2008. It is intended to mitigate an economic recession when inflation is very low or negative, making standard monetary policy ineffective. Quantitative tightening (QT) does the opposite, where for monetary policy reasons, a central bank sells off some portion of its holdings of government bonds or other financial assets.\n\nSimilar to conventional open-market operations used to implement monetary policy, a central bank implements quantitative easing by buying financial assets from commercial banks and other financial institutions, thus raising the prices of those financial assets and lowering their yield, while simultaneously increasing the money supply. However, in contrast to normal policy, quantitative easing usually involves the purchase of riskier or longer-term assets (rather than short-term government bonds) of predetermined amounts at a large scale, over a pre-committed period of time.\n\nCentral banks usually resort to quantitative easing when their nominal interest rate target approaches or reaches zero. Very low interest rates induce a liquidity trap, a situation where people prefer to hold cash or very liquid assets, given the low returns on other financial assets. This makes it difficult for interest rates to go below zero; monetary authorities may then use quantitative easing to further stimulate the economy rather than trying to lower the interest rate further.\n\nQuantitative easing can help bring the economy out of recession and help ensure that inflation does not fall below the central bank's inflation target. However QE programmes are also criticized for their side-effects and risks, which include the policy being more effective than intended in acting against deflation (leading to higher inflation in the longer term), or not being effective enough if banks remain reluctant to lend and potential borrowers are unwilling to borrow. Quantitative easing has also been criticized for raising financial asset prices, contributing to inequality. Quantitative easing was undertaken by some major central banks worldwide following the global financial crisis of 2007–08, and again in response to the COVID-19 pandemic.",

        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nWe test our system on the CALLHOME Spanish-English speech translation corpus, a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ).",

        "answer": "Frying shrimp is very easy, and requires simple equipment and ingredients. \n\nUse shrimp that is U-15 or less.  Frying shrimp that are larger than U-15 will result in tough shrimp.  First, clean and devein the shrimp, and then set them aside.  \n\nThen, heat vegetable, canola or peanut oil to 375 degrees.  These oils have a high smoke point (this is the temperature at which the oil will burn and smoke), and are good choices generally for frying.   Use a cast iron pan if you have one, or another good quality pan that retains heat evenly and well.  \n\nWhile the oil is heating, prep the flour. The crispness of the shrimp will depend on the type of flour that you use.  All purpose flour is readily available, and results in a nice, crispy shrimp.  Using rice flour will result in even more crispy shrimp, although rice flour is available at Asian grocery stores and is not readily available at general grocery stores. Using corn starch will result in the crispiest shrimp.  For one pound of shrimp, use 2 cups of whatever type of flour (or cornstarch) that you would prefer, and season the flour liberally with salt and pepper, and add some red pepper flakes if you prefer a little bit of spice.  \n\nAt this point, dry the shrimp and dredge the shrimp in the flour in relatively small batches.  Set aside until the oil is ready.\n\nOnce the oil is at 375 degrees, put a few shrimp in the oil, being careful not to crowd the pan.  Too many shrimp in the oil will result in less crispy shrimp, as well as shrimp that is oily.  You should use your judgment on how many shrimp to add, depending on the size of the shrimp and the size of the pan.  The shrimp will take only a few minutes in the oil to be done, again depending on the size of the shrimp.  The shrimp will be done once it’s no longer translucent.  For shrimp that is 21/25 count or larger, using a spider (which is a type of skimmer) will make it easier to get the shrimp out of the pan.

        "answer": "Because \" coldest\" has a shorter distance to the answer \" 0.3◦C\" .",
        "evidence": "Question Generation (QG) is the task of automatically creating questions from a range of inputs, such as natural language text BIBREF0, knowledge base BIBREF1 and image BIBREF2. QG is an increasingly important area in NLP with various application scenarios such as intelligence tutor systems, open-domain chatbots and question answering dataset construction. In this paper, we focus on question generation from reading comprehension materials like SQuAD BIBREF3. As shown in Figure FIGREF1, given a sentence in the reading comprehension paragraph and the text fragment (i.e., the answer) that we want to ask about, we aim to generate a question that is asked about the specified answer.\nQuestion generation for reading comprehension is firstly formalized as a declarative-to-interrogative sentence transformation problem with predefined rules or templates BIBREF4, BIBREF0. With the rise of neural models, Du2017LearningTA propose to model this task under the sequence-to-sequence (Seq2Seq) learning framework BIBREF5 with attention mechanism BIBREF6. However, question generation is a one-to-many sequence generation problem, i.e., several aspects can be asked given a sentence. Zhou2017NeuralQG propose the answer-aware question generation setting which assumes the answer, a contiguous span inside the input sentence, is already known before question generation. To capture answer-relevant words in the sentence, they adopt a BIO tagging scheme to incorporate the answer position embedding in Seq2Seq learning. Furthermore, Sun2018AnswerfocusedAP propose that tokens close to the answer fragments are more likely to be answer-relevant. Therefore, they explicitly encode the relative distance between sentence words and the answer via position embedding and position-aware attention.\nAlthough existing proximity-based answer-aware approaches achieve reasonable performance, we argue that such intuition may not apply to all cases especially for sentences with complex structure. For example, Figure FIGREF1 shows such an example where those approaches fail. This sentence contains a few facts and due to the parenthesis (i.e. “the area's coldest month”), some facts intertwine: “The daily mean temperature in January is 0.3$^\\circ $C” and “January is the area's coldest month”. From the question generated by a proximity-based answer-aware baseline, we find that it wrongly uses the word “coldest” but misses the correct word “mean” because “coldest” has a shorter distance to the answer “0.3$^\\circ $C”.\nIn summary, their intuition that “the neighboring words of the answer are more likely to be answer-relevant and have a higher chance to be used in the question” is not reliable. To quantitatively show this drawback of these models, we implement the approach proposed by Sun2018AnswerfocusedAP and analyze its performance under different relative distances between the answer and other non-stop sentence words that also appear in the ground truth question. The results are shown in Table TABREF2. We find that the performance drops at most 36% when the relative distance increases from “$0\\sim 10$” to “$>10$”. In other words, when the useful context is located far away from the answer, current proximity-based answer-aware approaches will become less effective, since they overly emphasize neighboring words of the answer.\nTo address this issue, we extract the structured answer-relevant relations from sentences and propose a method to jointly model such structured relation and the unstructured sentence for question generation. The structured answer-relevant relation is likely to be to the point context and thus can help keep the generated question to the point. For example, Figure FIGREF1 shows our framework can extract the right answer-relevant relation (“The daily mean temperature in January”, “is”, “32.6$^\\circ $F (0.3$^\\circ $C)”) among multiple facts. With the help of such structured information, our model is less likely to be confused by sentences with a complex structure. Specifically, we firstly extract multiple relations with an off-the-shelf Open Information Extraction (OpenIE) toolbox BIBREF7, then we select the relation that is most relevant to the answer with carefully designed heuristic rules.\nNevertheless, it is challenging to train a model to effectively utilize both the unstructured sentence and the structured answer-relevant relation because both of them could be noisy: the unstructured sentence may contain multiple facts which are irrelevant to the target question, while the limitation of the OpenIE tool may produce less accurate extracted relations. To explore their advantages simultaneously and avoid the drawbacks, we design a gated attention mechanism and a dual copy mechanism based on the encoder-decoder framework, where the former learns to control the information flow between the unstructured and structured inputs, while the latter learns to copy words from two sources to maintain the informativeness and faithfulness of generated questions.\nIn the evaluations on the SQuAD dataset, our system achieves significant and consistent improvement as compared to all baseline methods. In particular, we demonstrate that the improvement is more significant with a larger relative distance between the answer and other non-stop sentence words that also appear in the ground truth question. Furthermore, our model is capable of generating diverse questions for a single sentence-answer pair where the sentence conveys multiple relations of its answer fragment.\nFrom the question generated by a proximity-based answer-aware baseline, we find that it wrongly uses the word \" coldest\" but misses the correct word  \" mean\" because \" coldest\" has a shorter distance to the answer \" 0.3◦C\" .",

This study looks at how interesting the games were to the players in addition to overall coherence and genre resemblance. Both studies are performed across two genres: mystery and fairy-tales. This is done in part to test the relative effectiveness of our approach across different genres with varying thematic commonsense knowledge. The dataset used was compiled via story summaries that were scraped from Wikipedia via a recursive crawling bot. The bot searched pages for both for plot sections as well as links to other potential stories. From the process, 695 fairy-tales and 536 mystery stories were compiled from two categories: novels and short stories.

        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nMore recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis [3].",

        "evidence": "Measures of semantic similarity and relatedness quantify the degree to which two concepts are similar (e.g., INLINEFORM0 – INLINEFORM1 ) or related (e.g., INLINEFORM2 – INLINEFORM3 ). Semantic similarity can be viewed as a special case of semantic relatedness – to be similar is one of many ways that a pair of concepts may be related. The automated discovery of groups of semantically similar or related terms is critical to improving the retrieval BIBREF0 and clustering BIBREF1 of biomedical and clinical documents, and the development of biomedical terminologies and ontologies BIBREF2 .\nThere is a long history in using distributional methods to discover semantic similarity and relatedness (e.g., BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 ). These methods are all based on the distributional hypothesis, which holds that two terms that are distributionally similar (i.e., used in the same context) will also be semantically similar BIBREF7 , BIBREF8 . Recently word embedding techniques such as word2vec BIBREF9 have become very popular. Despite the prominent role that neural networks play in many of these approaches, at their core they remain distributional techniques that typically start with a word by word co–occurrence matrix, much like many of the more traditional approaches.\nHowever, despite these successes distributional methods do not perform well when data is very sparse (which is common). One possible solution is to use second–order co–occurrence vectors BIBREF10 , BIBREF11 . In this approach the similarity between two words is not strictly based on their co–occurrence frequencies, but rather on the frequencies of the other words which occur with both of them (i.e., second order co–occurrences). This approach has been shown to be successful in quantifying semantic relatedness BIBREF12 , BIBREF13 . However, while more robust in the face of sparsity, second–order methods can result in significant amounts of noise, where contextual information that is overly general is included and does not contribute to quantifying the semantic relatedness between the two concepts.\nOur goal then is to discover methods that automatically reduce the amount of noise in a second–order co–occurrence vector. We achieve this by incorporating pairwise semantic similarity scores derived from a taxonomy into our second–order vectors, and then using these scores to select only the most semantically similar co–occurrences (thereby reducing noise).\nWe evaluate our method on two datasets that have been annotated in multiple ways. One has been annotated for both similarity and relatedness, and the other has been annotated for relatedness by two different types of experts (medical doctors and medical coders). Our results show that integrating second order co–occurrences with measures of semantic similarity increases correlation with our human reference standards. We also compare our result to a number of other studies which have applied various word embedding methods to the same reference standards we have used. We find that our method often performs at a comparable or higher level than these approaches. These results suggest that our methods of integrating semantic similarity and relatedness values have the potential to improve performance of purely distributional methods.\nOur goal then is to discover methods that automatically reduce the amount of noise in a second–order co–occurrence vector.",

Krapp. The theatre was built by the Shubert family on a site previously occupied by the Mathushek & Son piano factory.\n\nThe first production at the theatre was the play Forever After, by Owen Davis, which opened in 1918. This moved to Playhouse Theatre for a long run. A musical, Somebody's Sweetheart (music by Antonio Bafunno; book and lyrics by Alonzo Price), was a success at the theatre in 1919–20. Oscar Hammerstein II made his debut as librettist in January 1920 with Always You, which was followed by a successful revue by Arthur Wimperis, As You Were. In July 1920, Poor Little Ritz Girl opened, with some songs by Rodgers and Hart and others by Sigmund Romberg and Alex Gerber. Afgar was another successful musical in 1920–21. The Gingham Girl was a hit musical in 1923 with music by Albert Von Tilzer.\n\nThe theatre introduced movies in 1921 and alternated the new medium with live theatre and American burlesque until 1957, although legitimate theatre was absent from 1934 to 1951. It changed its name to the Columbia Theatre in 1934, Gotham Theatre in 1944 and the Holiday Theatre in 1951. A successful revue, Bagels and Yox played in 1951. A revival of Abie's Irish Rose played in 1954. Legitimate theatre ended at the house in 1956. Under the names Odeon, then the Forum, and finally Movieland, the theatre played movies until 1988, when the Shuberts sold it. The building was converted into other uses. The auditorium became a disco, Club USA. The theatre was demolished in 1998. A W Hotel opened on the site in 2005.",

Tim was a quick learner and soon became very good at his job. As he gained more experience, Chad slowly stepped away, allowing Tim to take on more responsibility on his own.\nDespite this increased independence, Tim still reached out to Chad when he needed help or advice. Chad continued to guide him, but only as needed, letting Tim take the lead in his own professional development.\nAs Tim was promoted to a new role, he was assigned a new mentor - Rob - who followed the same approach as Chad. Tim threw himself into the new position, soaking up everything he could learn from Rob. Another five years passed by and he became very good at his job.\nHowever, after a decade of experience, Tim found himself at a crossroads, uncertain about what to do next. Over lunch one day, he confided in Jared, a manager from another team, about his indecisiveness. Jared listened attentively and asked Tim some probing questions to help him think through his options.\nTo each of Tim's responses, Jared asked more questions, guiding him towards a clearer understanding of his own goals and desires.

A good analogy of antioxidants in water is the following: ORP is like a big swimming pool of potential but at the moment its currently empty and dissolved hydrogen is like ball of finite size.  The larger the ORP 'swimming pool' the more dissolved hydrogen 'balls' can fit in that pool.  An ORP with a large negative value is huge swimming pool, and an OPR with a high positive value is no swimming pool.  ORP can also measure whether water is acidic or alkaline.

        "answer": "The Manchester City Football Club, commonly referred to as Man City, is an English football club based in Manchester that competes in the Premier League, the top division in the English football league system. It founded in 1880 as St. Mark's (West Gorton), then Ardwick Association Football Club in 1887 and Manchester City in 1894. The club's home ground is the Etihad Stadium in east Manchester, to which they moved in 2003, having played at Maine Road since 1923. Manchester City adopted their sky blue home shirts in 1894, in the first season with the current name. Since its inception, the club has won eight league titles, six FA Cups, eight League Cups, six FA Community Shields, and one European Cup Winners' Cup.\n\nThe club joined the Football League in 1892, and won their first major honour, the FA Cup, in 1904. The club had its first major period of success in the late 1960s and early 1970s, winning the league title, FA Cup, League Cup, and European Cup Winners Cup under the management of Joe Mercer and Malcolm Allison.

        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nThe contributions of the paper can be summed up as follows. 1. We provide a new perspective on how to compose the individual word of a sentence. Instead of directly using a learnable parameterized compositional function, we introduce a meta neural network, which can generate a compositional network to dynamically compose constituents over tree structure. 2. Experimental results show that the proposed architecture is more expressive due to its learning to learn nature, yet without increasing the number of model’s parameters. 3.

        "evidence": "In the first experiment the model was trained using pretrained vectors extracted from two different sources, Common Crawl and Wikipedia and can be found at the official FastText web page BIBREF8. Both sources were trained on the same algorithm called FastText BIBREF9, an extension of Word2Vec that treats tokens as an average sum of sub-words and finds similarities of words based on their n-grams. The configuration of the FastText model for Wikipedia vectors is according to BIBREF10, whilst the model for CC vectors is a position-weight CBOW 5 length n-grams with a window size of 5 tokens and 10 negative words. The file with the Common Crawl vectors consists of 2.000.000 tokens with 300 dimension, whereas the file with the Wikipedia vectors consists of 300.000 tokens with 300 dimension.The results can be viewed in the following table, with the first part describing the Common Crawl results and the second one the Wikipedia results.\nAt the results, POS and morph classes refer to the tag labels explained in SECREF4, whilst only POS classes relate to annotated labels that describe only the part of speech. It is evident that even though the CC vectors are noisy, coming from a web source, they lead to better results than Wikipedia, possibly because they have a larger variety of tokens.\nIn the next experiment, the dataset was used for the composition of embeddings for the part of speech tagger. The dataset was trained on a FastText model with the same parameters that extracted the Common Crawl vectors. As a result, 140.000 vectors with 300 dimension were exported. It must be mentioned that the tagset with the morphological features was used.\nThe values of the metrics in this case were almost as good and comparable to the CC ones. However, the model trained with a larger vocabulary had higher results. Also, the model with the dataset vectors did not have the flexibility to classify unknown words.\nAs a next step, the test set of the dataset was altered by replacing words with syntactical mistakes to test the tolerance of the model in OOV words. Suffixes of verbs were altered and vowels were replaced with others, affecting 20% of the tokens of the dataset. Using again the more complex tagset for training, the results can be found in Table 3.\nWhat can be concluded is that the model did not have a flexibility in OOV words. Of course, this can also be an advantage, meaning that the model recognized the mismatch of a wrong word with its class.\nOne disadvantage that the previous model had is that for unknown words the model assigned a zero vector, affecting the testing results. In order to minimize this problem, the unknown words were first passed through a FastText model to get a vector from their subwords. The resulting vectors were imported in the vocabulary with the CC vectors before training. The model was also trained using as a vocabulary the unknown words and the tokens from the Common Crawl vectors, both buffered in the same FastText model. Results are listed in Table 4.\nIt was noticed that the model performed better when using the vectors from different FastText models. It was expected that the second experiment would have performed better, as the tokens were inserted into the same FastText model and the vectors exported from both sources should match.\nBoth datasets were fed into the library in proper format for training. In training process, the entity recognizer had the same configuration with the POS tagger, using the same percentages for train, validation and test sets. It must be noted that all the models used the Common Crawl pretrained vectors for a vocabulary. The results are compared using the macro F1 score.\nAt first the datasets from both sources (Makedonia, Wikipedia) were used for training with 10 iterations and testing from the model. The results can be viewed in the following table:\nIt seemed that the average F1 score was higher for the Makedonia corpus, as it was the basis of the configuration for the keyword list. In order to have an objective evaluation, the results of each corpus per entity class were observed.\nBoth sources had good results in non entity tokens, which affected the F1 score. Moreover, the model did not perform well for facilities, as polyglot's Greek recognizer does not support that class and FAC entities cover a small amount of the list.\nIn the second experiment, the datasets were compared to a common test set that followed the desired set of rules.\nAgain, the Makedonia corpus performed better, because of the proper annotation on the keyword list.\nIn an experiment worth mentioning the correlation of the part of speech with the performance of the recognizer was explored. In this experiment, both pipelines (part of speech, entity recognition) were used for training with 30 iterations and the model was trained twice: with and without the usage of the part of speech information for recognition.\nIt is evident that the recognizer did not gain knowledge from the part of speech tags of the tokens.\nIn an experiment worth mentioning the correlation of the part of speech with the performance of the recognizer was explored.

        "answer": "1%.",
        "evidence": "The ability to continuously learn and accumulate knowledge throughout a lifetime and reuse it effectively to adapt to a new problem quickly is a hallmark of general intelligence. State-of-the-art machine learning models work well on a single dataset given enough training examples, but they often fail to isolate and reuse previously acquired knowledge when the data distribution shifts (e.g., when presented with a new dataset)—a phenomenon known as catastrophic forgetting BIBREF0 , BIBREF1 .\nThe three main approaches to address catastrophic forgetting are based on: (i) augmenting the loss function that is being minimized during training with extra terms (e.g., a regularization term, an optimization constraint) to prevent model parameters learned on a new dataset from significantly deviating from parameters learned on previously seen datasets BIBREF2 , BIBREF3 , BIBREF4 , (ii) adding extra learning phases such as a knowledge distillation phase, an experience replay BIBREF5 , BIBREF6 , and (iii) augmenting the model with an episodic memory module BIBREF7 . Recent methods have shown that these approaches can be combined—e.g., by defining optimization constraints using samples from the episodic memory BIBREF8 , BIBREF9 .\nIn language learning, progress in unsupervised pretraining BIBREF10 , BIBREF11 , BIBREF12 has driven advances in many language understanding tasks BIBREF13 , BIBREF14 . However, these models have been shown to require a lot of in-domain training examples, rapidly overfit to particular datasets, and are prone to catastrophic forgetting BIBREF15 , making them unsuitable as a model of general linguistic intelligence.\nIn this paper, we investigate the role of episodic memory for learning a model of language in a lifelong setup. We propose to use such a component for sparse experience replay and local adaptation to allow the model to continually learn from examples drawn from different data distributions. In experience replay, we randomly select examples from memory to retrain on. Our model only performs experience replay very sparsely to consolidate newly acquired knowledge with existing knowledge in the memory into the model. We show that a 1% experience replay to learning new examples ratio is sufficient. Such a process bears some similarity to memory consolidation in human learning BIBREF16 . In local adaptation, we follow Memory-based Parameter Adaptation BIBREF7 and use examples retrieved from memory to update model parameters used to make a prediction of a particular test example.\nOur setup is different than a typical lifelong learning setup. We assume that the model only makes one pass over the training examples, similar to BIBREF9 . However, we also assume neither our training nor test examples have dataset identifying information (e.g., a dataset identity, a dataset descriptor). Our experiments focus on lifelong language learning on two tasks—text classification and question answering. BIBREF17 show that many language processing tasks (e.g., classification, summarization, natural language inference, etc.) can be formulated as a question answering problem. We argue that our lifelong language learning setup—where a model is presented with question-answer examples without an explicit identifier about which dataset (distribution) the examples come from—is a more realistic setup to learn a general linguistic intelligence model.\nOur main contributions in this paper are:\nOur model only performs experience replay very sparsely to consolidate newly acquired knowledge with existing knowledge in the memory into the model.

        "question": "How does ROUGE evaluate system-generated summaries?",
        "answer": "By comparing them to a set of human written gold-standard summaries.",
        "evidence": "Automatic text summarization has been an active research area in natural language processing for several decades. To compare and evaluate the performance of different summarization systems, the most intuitive approach is assessing the quality of the summaries by human evaluators. However, manual evaluation is expensive and the obtained results are subjective and difficult to reproduce BIBREF0 . To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nROUGE (Lin, 2004) is one of the first and most widely used metrics in summarization evaluation.

        "question": "Can you extract the 5 most important characteristics of the moon from this literature in a single paragraph?",
        "evidence": "The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System.It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at 0.1654 g, with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density.\n\nThe Moon orbits Earth at an average distance of 384,400 km (238,900 mi), or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period of 29.5 days, the amount of visible surface illuminated by the Sun varies from none up to 100%, resulting in lunar phases that form the basis for the months of a lunar calendar. The Moon is tidally locked to Earth, which means that the length of a full rotation of the Moon on its own axis causes its same side (the near side) to always face Earth, and the somewhat longer lunar day is the same as the synodic period. However, 59% of the total lunar surface can be seen from Earth through cyclical shifts in perspective known as libration.\n\nThe most widely accepted origin explanation posits that the Moon formed 4.51 billion years ago, not long after Earth, out of the debris from a giant impact between the planet and a hypothesized Mars-sized body called Theia. It then receded to a wider orbit because of tidal interaction with the Earth. The near side of the Moon is marked by dark volcanic maria (\"seas\"), which fill the spaces between bright ancient crustal highlands and prominent impact craters. Most of the large impact basins and mare surfaces were in place by the end of the Imbrian period, some three billion years ago. The lunar surface is fairly non-reflective, with the reflectance of lunar soil being comparable to that of asphalt. However, due to its large angular diameter, the full moon is the brightest celestial object in the night sky. The Moon's apparent size is nearly the same as that of the Sun, allowing it to cover the Sun almost completely during a total solar eclipse.\n\nBoth the Moon's prominence in Earth's sky and its regular cycle of phases have provided cultural references and influences for human societies throughout history. Such influences can be found in language, calendar systems, art, and mythology. The first artificial object to reach the Moon was the Soviet Union's uncrewed Luna 2 spacecraft in 1959; this was followed by the first successful soft landing by Luna 9 in 1966. The only human lunar missions to date have been those of the United States' Apollo program, which landed twelve men on the surface between 1969 and 1972.

        "question": "Why is the multilingual model deficient?",
        "answer": "Since the aligned roles are being generated twice.",
        "evidence": "The multilingual model uses word alignments between sentences in a parallel corpus to exploit role correspondences across languages. We make copies of the monolingual model for each language and add additional crosslingual latent variables (CLVs) to couple the monolingual models, capturing crosslingual semantic role patterns. Concretely, when training on parallel sentences, whenever the head words of the arguments are aligned, we add a CLV as a parent of the two corresponding role variables. Figure FIGREF16 illustrates this model. The generative process, as explained below, remains the same as the monolingual model for the most part, with the exception of aligned roles which are now generated by both the monolingual process as well as the CLV.\nEvery predicate-tuple has its own inventory of CLVs specific to that tuple. Each CLV INLINEFORM0 is a multi-valued variable where each value defines a distribution over role labels for each language (denoted by INLINEFORM1 above). These distributions over labels are trained to be peaky, so that each value INLINEFORM2 for a CLV represents a correlation between the labels that INLINEFORM3 predicts in the two languages. For example, a value INLINEFORM4 for the CLV INLINEFORM5 might give high probabilities to INLINEFORM6 and INLINEFORM7 in language 1, and to INLINEFORM8 in language 2. If INLINEFORM9 is the only value for INLINEFORM10 that gives high probability to INLINEFORM11 in language 1, and the monolingual model in language 1 decides to assign INLINEFORM12 to the role for INLINEFORM13 , then INLINEFORM14 will predict INLINEFORM15 in language 2, with high probability. We generate the CLVs via a Chinese Restaurant Process BIBREF11 , a non-parametric Bayesian model, which allows us to induce the number of CLVs for every predicate-tuple from the data. We continue to train on the non-parallel sentences using the respective monolingual models.\nThe multilingual model is deficient, since the aligned roles are being generated twice. Ideally, we would like to add the CLV as additional conditioning variables in the monolingual models. The new joint probability can be written as equation UID11 (Figure FIGREF7 ), which can be further decomposed following the decomposition of the monolingual model in Figure FIGREF7 . However, having this additional conditioning variable breaks the Dirichlet-multinomial conjugacy, which makes it intractable to marginalize out the parameters during inference. Hence, we use an approximation where we treat each of the aligned roles as being generated twice, once by the monolingual model and once by the corresponding CLV (equation ).\nThis is the first work to incorporate the coupling of aligned arguments directly in a Bayesian SRL model. This makes it easier to see how to extend this model in a principled way to incorporate additional sources of information. First, the model scales gracefully to more than two languages. If there are a total of INLINEFORM0 languages, and there is an aligned argument in INLINEFORM1 of them, the multilingual latent variable is connected to only those INLINEFORM2 aligned arguments.\nSecond, having one joint Bayesian model allows us to use the same model in various semi-supervised learning settings, just by fixing the annotated variables during training. Section SECREF29 evaluates a setting where we have some labeled data in one language (called source), while no labeled data in the second language (called target). Note that this is different from a classic annotation projection setting (e.g. BIBREF12 ), where the role labels are mapped from source constituents to aligned target constituents.\nThe multilingual model is deficient, since the aligned roles are being generated twice.",

        "answer": "probe what features of language drive these event-related potentials (ERPs) responses, and in turn to probe what features of language mediate the cognitive processes that underlie human language comprehension, and especially the integration of meaning across words",
        "evidence": "The cognitive processes involved in human language comprehension are complex and only partially identified. According to the dual-stream model of speech comprehension BIBREF1 , sound waves are first converted to phoneme-like features and further processed by a ventral stream that maps those features onto words and semantic structures, and a dorsal stream that (among other things) supports audio-short term memory. The mapping of words onto meaning is thought to be subserved by widely distributed regions of the brain that specialize in particular modalities — for example visual aspects of the word banana reside in the occipital lobe of the brain and are activated when the word banana is heard BIBREF2 — and the different representation modalities are thought to be integrated into a single coherent latent representation in the anterior temporal lobe BIBREF3 . While this part of meaning representation in human language comprehension is somewhat understood, much less is known about how the meanings of words are integrated together to form the meaning of sentences and discourses. One tool researchers use to study the integration of meaning across words is electroencephelography (EEG), which measures the electrical activity of large numbers of neurons acting in concert. EEG has the temporal resolution necessary to study the processes involved in meaning integration, and certain stereotyped electrical responses to word presentations, known as event-related potentials (ERPs), have been identified with some of the processes thought to contribute to comprehension.\n\nIn this work, we consider six ERP components that have been associated in the cognitive neuroscience and psycholinguistics literature with language processing and which we analyze in the data from BIBREF0 (see Figure FIGREF1 for spatial and temporal definitions of these ERP components). Three of these — the N400, EPNP, and PNP responses — are primarily considered markers for semantic processing, while the other three — the P600, ELAN, and LAN responses — are primarily considered markers for syntactic processing. However, the neat division of the ERP responses into either semantic or syntactic categories is controversial. The N400 response has been very well studied (for an overview see BIBREF4 ) and it is well established that it is associated with semantic complexity, but the features of language that trigger the other ERP responses we consider here are poorly understood. We propose to use a neural network pretrained as a language model to probe what features of language drive these ERP responses, and in turn to probe what features of language mediate the cognitive processes that underlie human language comprehension, and especially the integration of meaning across words.\nWe propose to use a neural network pretrained as a language model to probe what features of language drive these ERP responses, and in turn to probe what features of language mediate the cognitive processes that underlie human language comprehension, and especially the integration of meaning across words.",

        "evidence": "The goal of sentence simplification is to compose complex sentences into simpler ones so that they are more comprehensible and accessible, while still retaining the original information content and meaning. Sentence simplification has a number of practical applications. On one hand, it provides reading aids for people with limited language proficiency BIBREF1 , BIBREF2 , or for patients with linguistic and cognitive disabilities BIBREF3 . On the other hand, it can improve the performance of other NLP tasks BIBREF4 , BIBREF5 , BIBREF6 . Prior work has explored monolingual machine translation (MT) approaches, utilizing corpora of simplified texts, e.g., Simple English Wikipedia (SEW), and making use of statistical MT models, such as phrase-based MT (PBMT) BIBREF7 , BIBREF8 , BIBREF9 , tree-based MT (TBMT) BIBREF10 , BIBREF11 , or syntax-based MT (SBMT) BIBREF12 .\nInspired by the success of neural MT BIBREF13 , BIBREF14 , recent work has started exploring neural simplification with sequence to sequence (Seq2seq) models, also referred to as encoder-decoder models. Nisioi et al. Nisioi:17 implemented a standard LSTM-based Seq2seq model and found that they outperform PBMT, SBMT, and unsupervised lexical simplification approaches. Zhang and Lapata BIBREF15 viewed the encoder-decoder model as an agent and employed a deep reinforcement learning framework in which the reward has three components capturing key aspects of the target output: simplicity, relevance, and fluency. The common practice for Seq2seq models is to use recurrent neural networks (RNNs) with Long Short-Term Memory BIBREF16 or Gated Recurrent Unit BIBREF17 for the encoder and decoder BIBREF18 , BIBREF15 . These architectures were designed to be capable of memorizing long-term dependencies across sequences. Nevertheless, their memory is typically small and might not be enough for the simplification task, where one is confronted with long and complicated sentences. In this study, we go beyond the conventional LSTM/GRU-based Seq2seq models and propose to use a memory-augmented RNN architecture called Neural Semantic Encoders (NSE). This architecture has been shown to be effective in a wide range of NLP tasks BIBREF0 . The contribution of this paper is twofold:\n(1) First, we present a novel simplification model which is, to the best of our knowledge, the first model that use memory-augmented RNN for the task. We investigate the effectiveness of neural Seq2seq models when different neural architectures for the encoder are considered. Our experiments reveal that the NseLstm model that uses an NSE as the encoder and an LSTM as the decoder performed the best among these models, improving over strong simplification systems. (2) Second, we perform an extensive evaluation of various approaches proposed in the literature on different datasets. Results of both automatic and human evaluation show that our approach is remarkably effective for the task, significantly reducing the reading difficulty of the input, while preserving grammaticality and the original meaning. We further discuss some advantages and disadvantages of these approaches.\nOur experiments reveal that the NSELSTM model that uses an NSE as the encoder and an LSTM as the decoder performed the best among these models, improving over strong simplification systems.",

Based on how long you wish to be exposed to the market choosing an asset type that aligns with your time horizon is very important in your investment strategy.\n\n- Risk Profile:  Indicates how confortable you are with the impact fluctuating market conditions have in your investments. Higher risk assets offer the biggest returns but they also have a higher chance of going down or loosing your investment completely. Understanding your risk profile is the first step in investing your money well. There are different investments assets that fit into different risk levels, a combination of these will offer a balanced way of investing your money. \n\n- Active/Passive investor: Depending on how much you want to be involved in the asset selection and allocation you would be considered an active investor or passive investor. Active investors are investors that spend extensive amount of time analysing the market and choosing assets for their portfolio. These investors may invest directly into stocks or stock options.

        "answer": "NMT system.",
        "evidence": "The past several years have witnessed a significant progress in Neural Machine Translation (NMT). Most NMT methods are based on the encoder-decoder architecture BIBREF0 , BIBREF1 , BIBREF2 and can achieve promising translation performance in a variety of language pairs BIBREF3 , BIBREF4 , BIBREF5 .\nHowever, recent studies BIBREF6 , BIBREF7 show that NMT often generates words that make target sentences fluent, but unfaithful to the source sentences. In contrast, traditional Statistical Machine Translation (SMT) methods tend to rarely make this kind of mistakes. Fig. 1 shows an example that NMT makes mistakes when translating the phrase “jinkou dafu xiahua (the sharp decline in imports)” and the phrase “maoyi shuncha (the trade surplus)”, but SMT can produce correct results when translating these two phrases. BIBREF6 argues that the reason behind this is the use of distributed representations of words in NMT makes systems often generate words that seem natural in the context, but do not reflect the content of the source sentence. Traditional SMT can avoid this problem as it produces the translations based on phrase mappings.\nTherefore, it will be beneficial to combine SMT and NMT to alleviate the previously mentioned problem. Actually, researchers have made some effective attempts to achieve this goal. Earlier studies were based on the SMT framework, and have been deeply discussed in BIBREF8 . Later, the researchers transfers to NMT framework. Specifically, coverage mechanism BIBREF9 , BIBREF10 , SMT features BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 and translation lexicons BIBREF6 , BIBREF16 , BIBREF17 have been fully explored. In contrast, phrase translation table, as the core of SMT, has not been fully studied. Recently, BIBREF18 and BIBREF19 explore the possibility of translating phrases in NMT. However, the “phrase” in their approaches are different from that used in phrase-based SMT. In BIBREF18 's models, the phrase pair must be a one-to-one mapping with a source phrase having a unique target phrase (named entity translation pairs). In BIBREF19 's models, the source side of a phrase pair must be a chunk. Therefore, it is still a big challenge to incorporate any phrase pair in the phrase table into NMT system to alleviate the unfaithfulness problem.\nIn this paper, we propose an effective method to incorporate a phrase table as recommendation memory into the NMT system. To achieve this, we add bonuses to the words in recommendation set to help NMT make better predictions. Generally, our method contains three steps. 1) In order to find out which words are worthy to recommend, we first derive a candidate target phrase set by searching the phrase table according to the input sentence. After that, we construct a recommendation word set at each decoding step by matching between candidate target phrases and previously translated target words by NMT. 2) We then determine the specific bonus value for each recommendable word by using the attention vector produced by NMT and phrase translation probability extracted from phrase table. 3) Finally we integrate the word bonus value into the NMT system to improve the final results.\nIn this paper, we make the following contributions:\n1) We propose a method to incorporate the phrase table as recommendation memory into NMT system. We design a novel approach to find from the phrase table the target words worthy of recommendation, calculate their recommendation scores and use them to promote NMT to make better predictions.\n2) Our empirical experiments on Chinese-English translation and English-Japanese translation tasks show the efficacy of our methods. For Chinese-English translation, we can obtain an average improvement of 2.23 BLEU points. For English-Japanese translation, the improvement can reach 1.96 BLEU points. We further find that the phrase table is much more beneficial than bilingual lexicons to NMT.\n3) Finally we integrate the word bonus value into the NMT system to improve the final results.",

License details: http://creativecommons.org/licenses/by/4.0/ Deep neural networks have been widely used in text classification and have achieved promising results BIBREF0 , BIBREF1 , BIBREF2 . Most focus on content information and use models such as convolutional neural networks (CNN) BIBREF3 or recursive neural networks BIBREF4 . However, for user-generated posts on social media like Facebook or Twitter, there is more information that should not be ignored. On social media platforms, a user can act either as the author of a post or as a reader who expresses his or her comments about the post.\nIn this paper, we classify posts taking into account post authorship, likes, topics, and comments. In particular, users and their “likes” hold strong potential for text mining. For example, given a set of posts that are related to a specific topic, a user's likes and dislikes provide clues for stance labeling. From a user point of view, users with positive attitudes toward the issue leave positive comments on the posts with praise or even just the post's content; from a post point of view, positive posts attract users who hold positive stances. We also investigate the influence of topics: different topics are associated with different stance labeling tendencies and word usage. For example we discuss women's rights and unwanted babies on the topic of abortion, but we criticize medicine usage or crime when on the topic of marijuana BIBREF5 . Even for posts on a specific topic like nuclear power, a variety of arguments are raised: green energy, radiation, air pollution, and so on. As for comments, we treat them as additional text information. The arguments in the comments and the commenters (the users who leave the comments) provide hints on the post's content and further facilitate stance classification.\nIn this paper, we propose the user-topic-comment neural network (UTCNN), a deep learning model that utilizes user, topic, and comment information. We attempt to learn user and topic representations which encode user interactions and topic influences to further enhance text classification, and we also incorporate comment information. We evaluate this model on a post stance classification task on forum-style social media platforms. The contributions of this paper are as follows: 1. We propose UTCNN, a neural network for text in modern social media channels as well as legacy social media, forums, and message boards — anywhere that reveals users, their tastes, as well as their replies to posts. 2. When classifying social media post stances, we leverage users, including authors and likers. User embeddings can be generated even for users who have never posted anything. 3. We incorporate a topic model to automatically assign topics to each post in a single topic dataset. 4. We show that overall, the proposed method achieves the highest performance in all instances, and that all of the information extracted, whether users, topics, or comments, still has its contributions.\nWe show that overall, the proposed method achieves the highest performance in all instances, and that all of the information extracted, whether users, topics, or comments, still has its contributions.",

        "evidence": "We first discuss a few baseline methods and then discuss the proposed approach. In all these methods, an embedding is generated for a tweet and is used as its feature representation with a classifier.\nBaseline Methods: As baselines, we experiment with three broad representations. (1) Char n-grams: It is the state-of-the-art method BIBREF0 which uses character n-grams for hate speech detection. (2) TF-IDF: TF-IDF are typical features used for text classification. (3) BoWV: Bag of Words Vector approach uses the average of the word (GloVe) embeddings to represent a sentence. We experiment with multiple classifiers for both the TF-IDF and the BoWV approaches.\nProposed Methods: We investigate three neural network architectures for the task, described as follows. For each of the three methods, we initialize the word embeddings with either random embeddings or GloVe embeddings. (1) CNN: Inspired by Kim et. al BIBREF3 's work on using CNNs for sentiment classification, we leverage CNNs for hate speech detection. We use the same settings for the CNN as described in BIBREF3 . (2) LSTM: Unlike feed-forward neural networks, recurrent neural networks like LSTMs can use their internal memory to process arbitrary sequences of inputs. Hence, we use LSTMs to capture long range dependencies in tweets, which may play a role in hate speech detection. (3) FastText: FastText BIBREF4 represents a document by average of word vectors similar to the BoWV model, but allows update of word vectors through Back-propagation during training as opposed to the static word representation in the BoWV model, allowing the model to fine-tune the word representations according to the task.\nAll of these networks are trained (fine-tuned) using labeled data with back-propagation. Once the network is learned, a new tweet is tested against the network which classifies it as racist, sexist or neither. Besides learning the network weights, these methods also learn task-specific word embeddings tuned towards the hate speech labels. Therefore, for each of the networks, we also experiment by using these embeddings as features and various other classifiers like SVMs and GBDTs as the learning method.\nFor each of the three methods, we initialize the word embeddings with either random embeddings or GloVe embeddings.",

Didius Julianus, who purchased the title from the Praetorian Guard, succeeded Pertinax, but was ousted by Septimius Severus and executed on June 1. Severus was declared Caesar by the Senate, but Pescennius Niger was hostile when he declared himself emperor. This started the civil war between Niger and Severus; both gathered troops and fought throughout the territory of the empire. Due to this war, Severus allowed Clodius Albinus, whom he suspected of being a threat, to be co-Caesar so that Severus did not have to preoccupy himself with imperial governance. This move allowed him to concentrate on waging the war against Niger. Most historians count Severus and Albinus as two emperors, though they ruled simultaneously.

Next, all occurrences of separators (full stops, commas and semicolons) are used to divide the text into separate chunks (3). The following step employs shallow parsing annotation – only nominal groups that appear at the beginning of the chunks are passed on (4). The first chunk that does not fulfil this requirement and all its successors get excluded from further analysis (4.1). Finally, we split the coordination groups and check, whether their lemmas correspond to any lexemes in WordNet (5). If not, the process repeats with the group replaced by its semantic head.

        "evidence": "The Osborne effect is a social phenomenon of customers canceling or deferring orders for the current, soon-to-be-obsolete product as an unexpected drawback of a company's announcing a future product prematurely. It is an example of cannibalization.\nThe term alludes to the Osborne Computer Corporation, whose second product did not become available until more than a year after it was announced. The company's subsequent bankruptcy was widely blamed on reduced sales after the announcement.\nThe Osborne Effect states that prematurely discussing future, unavailable products damages sales of existing products. The name comes from the planned replacement of the Osborne 1, an early personal computer first sold by the Osborne Computer Corporation in 1981. In 1983, founder Adam Osborne pre-announced several next-generation computer models (the Osborne Executive and Osborne Vixen), which were only prototypes, highlighting the fact that they would outperform the existing model as the prototypes dramatically cut down assembly time. A widely held belief was that sales of the Osborne 1 fell sharply as customers anticipated those more advanced systems, leading to a sales decline from which Osborne Computer was unable to recover. This belief appeared in the media almost immediately after the company's September 1983 bankruptcy:\n\nTo give the jazzy $2,495 Osborne Executive a running start, Adam began orchestrating publicity early in 1983. We, along with many other magazines, were shown the machine in locked hotel rooms. We were required not to have anything in print about it until the planned release date in mid-April. As far as we know, nothing did appear in print, but dealers heard about the plans and cancelled orders for the Osborne 1 in droves. In early April, Osborne told dealers he would be showing them the machine on a one-week tour the week of 17 April, and emphasized that the new machine was not a competitor for the Osborne 1. But dealers didn't react the way Osborne expected; said Osborne, \"All of them just cancelled their orders for the Osborne 1.\"\n\nOsborne reacted by drastically cutting prices on the Osborne 1 in an effort to stimulate cash flow. But nothing seemed to work, and for several months sales were practically non-existent.\n\nPre-announcement is done for several reasons: to reassure current customers that there is improvement or lower cost coming, to increase the interest of the media and investors in the company's future prospects, and to intimidate or confuse competitors. When done correctly, the sales or cash flow impact to the company is minimal, with the revenue drop for the current product being offset by orders or completed sales of the new product as it becomes available. However, when the Osborne effect occurs, the quantity of unsold goods increases and the company must react by discounting and/or lowering production of the current product, both of which depress cash flow.",

        "evidence": "We propose a Bayesian model of semantic role induction (SRI) that uses crosslingual latent variables to capture role alignments in parallel corpora. The crosslingual latent variables capture correlations between roles in different languages, and regularize the parameter estimates of the monolingual models. Because this is a joint Bayesian model of multilingual SRI, we can apply the same model to a variety of training scenarios just by changing the inference procedure appropriately. We evaluate monolingual SRI with a large unlabeled dataset, bilingual SRI with a parallel corpus, bilingual SRI with annotations available for the source language, and monolingual SRI with a small labeled dataset. Increasing the amount of monolingual unlabeled data significantly improves SRI in German but not in English. Adding word alignments in parallel sentences results in small, non significant improvements, even if there is some labeled data available in the source language. This difficulty in showing the usefulness of parallel corpora for SRI may be due to the current assumptions about role alignments, which mean that only a small percentage of roles are aligned. Further analyses reveals that annotating small amounts of data can easily outperform the performance gains obtained by adding large unlabeled dataset as well as adding parallel corpora.\nFuture work includes training on different language pairs, on more than two languages, and with more inclusive models of role alignment.\nIncreasing the amount of monolingual unlabeled data significantly improves SRI in German but not in English.",

        "answer": "We discussed the case in the 3rd paragraph of Sec 4.1, following which we provide the intuition (in our initial submission). The stated intuition is consistent with the reviewer's opinion: \"Intuitively, as a consequence of the budget constraint, fewer training clients are able to participate in training wider networks, where the reduced sample size or model size greatly impacted the generalization.\"",
        "evidence": "For motivation, we set up a standard non-i.i.d. FL benchmark using DomainNet dataset (refer to experimental details in Section 5) and study how the budget constraint impedes effective training of customizable models. Case 1: FL without budget constraint. First, we individually train networks of different widths by FedAvg. We see that the slimmer networks converge slower and are less generalizable, even though they are trained on all clients (solid lines in Fig.).\nThe results justified the motivation of training wider networks than slimmer ones.\nCase 2: FL with budget constraint. Following the above budget constraint, i.e., R k = (1/2) ⌈4k/K⌉ , we deploy HeteroFL to train budget-compatible prototype models locally. Since HeteroFL was not designed for model customization, data are not fully used: each model prototype is only trained by 1/4 of clients, when clients of the R k = 1 budget can actually afford all slimmer models. Therefore, we extend HeteroFL to a slimmable version (SHeteroFL) by training all affordable prototypes locally. As shown in Fig., wider models (e.g., ×1 net) converge to validation accuracy lower than not only the FedAvg counterparts, but also the slimmer ×0.25 net, showing that the widest model may not be a good candidate model. Therefore, switching models to wider configurations lowers efficiency but does not improve accuracy, which is not a valid customization.\nFrom the perspective of data allocation, it is not surprising that SHeteroFL exhibits a non-monotonous relation between the model width and accuracy. For ×1 nets, only 1/4 clients and data are accessible for training. In comparison, 3/4 data are accessible by ×0.25 nets and the more data empowers ×0.25 nets better generalization ability than ×1 nets.\nAs shown in Fig. 2, wider models (e.g., ×1 net) converge to validation accuracy lower than not only the FedAvg counterparts,but also the slimmer ×0.25 net, showing that the widest model may not be a good candidate model. Therefore, switching models to wider configurations lowers efficiency but does not improve accuracy,\nwhich is not a valid customization.

        "question": "What are the advantages and disadvantages of learning Java over Python?",
        "evidence": "",
        "answer": "Java and Python are two of the most popular programming languages. Of the two, Java is the faster language, but Python is simpler and easier to learn. Each is well-established, platform-independent, and part of a large, supportive community. But that is where the similarities end. When you’re considering Python versus Java, each language has different uses for different purposes, and each has pros and cons to consider.\n\nAdvantages of Java\n\nSpeed and efficiency are two of the big draws of using Java. It's also one of the coding languages considered to be easy to learn. Because many of the processes of this high-level language run automatically, you won't have to do an intense study of how everything works as much as you would with a low-level language. You should be able to master it relatively quickly depending on how much time you can devote to learning and practicing. Other advantages of using Java include the following:\n\n(1) It's simple: The syntax is straightforward, making it easy to write. It's not as complex as languages like C++, and it uses automatic memory allocation.\n\n(2) It’s platform independent: You can use Java on multiple types of computers, including Windows, iOS, Unix, and Linux systems, as long as it has the Java Virtual Machine (JVM) platform.\n\n(3) It’s object oriented: Because you create classes containing data and functions and objects that belong to those classes, it offers a more intuitive approach for big project development. It also provides flexibility and easier troubleshooting, and the ability to reuse the code.\n\n(4) It has a large global community: This is helpful when you're learning Java or should you run into any problems.\n\n(5) It supports multithreading: When you use Java, you can run more than one thread at a time. When running multiple threads, they share a common memory area to increase efficiency and performance.\n\n(6) It’s secure: Java avoids using explicit pointers, runs inside a virtual machine called a sandbox, uses byte-code verifier to check for illegal code, and provides library-level safety along with Java security package and run-time security checks. \n\nDisadvantages of Java\n\nBefore deciding whether Java is the right programming language for you to start with, it’s essential to consider its weaknesses. One of the main downsides to using Java is that it uses a large amount of memory—considerably more than Python.\n\nAdditionally, Java manages its memory through garbage collection, which happens once the application you’re working on no longer references the object. Java’s garbage collector clears it from memory, but during the process, other threads have to stop while the garbage collector works. The step impacts the overall performance of the application. Other disadvantages include:\n\n(1) It doesn’t offer control over garbage collection: As a programmer, you won’t have the ability to control garbage collection using functions like free() or delete().\n\n(2) It has a lot of words: Although Java is simple, it does tend to have a lot of words in it, which will often leave you with complex, lengthy sentences and explanations.\n\n(3) It doesn't have a native look when you use it for desktops: Java has multiple graphical user interface (GUI) builders, but they aren't the best if you're creating complex UI on a desktop. Java is weaker when you're using it for desktop versus mobile when it comes to user experience and user interface. While there are many GUI builders to choose from, you'll need to do a lot of research to find the right one for your project.\n\n\nPython: The simple path\n\nAlthough Java is faster, Python is more versatile, easier to read, and has a simpler syntax. According to Stack Overflow, this general use, interpreted language is the fourth most popular coding language.  It's also one of the most in-demand programming languages that hiring managers look for when hiring candidates, according to HackerRank, second only to JavaScript. \n\nPython's popularity has experienced explosive growth in the past few years, with more than 11.3 million coders choosing to use it, mainly for IoT, data science, and machine learning applications, according to ZDNet. Further, Python has had a 25 percent growth rate, adding 2.3 million developers to its community between Q3 2020 and Q3 2021, according to SlashData's “State of the Developer Nation.”.\n\nAdvantages of Python\n\nPython’s versatility is difficult to match, and it's so flexible that it encourages experimentation. This keeps programmers from being pigeonholed into only building one type of application. You can learn just one language and use it to make new and different things.\n\nComputer Weekly calls Python the most versatile programming language, noting that “Although there might be a better solution for any given problem, Python will always get the job done well”. Other advantages of Python include:\n\n(1) It’s platform-independent: Like Java, you can use Python on various platforms, including macOS, Windows, and Linux. You’ll just need an interpreter designed for that platform.\n\n(2) It allows for fast development: Because Python is dynamically typed, it's fast and friendly for development. Additionally, it uses asynchronous code to tackle situations and challenges faster because each unit of code runs separately.\n\n(3) It offers extensive libraries: Its large library supports common tasks and commands. It also contains code that can be used for many different purposes, ranging from generating documentation to unit testing to CGI.\n\n(4) It offers a more flexible approach to programming: Python supports a variety of programming styles and has multiple paradigms. Not only is this optimal for programmers who enjoy flexibility, but it also makes it ideal for start-ups that might need to shift approaches abruptly.\n\n(5) It's free and open-source: You can download Python without any cost, and because it's so easy to learn and boasts one of the largest and most active communities—you should be able to start writing code in mere minutes.\n\n(6) It may boost productivity: NetGuru says that Python is more productive than Java because of how concise it is and because it's dynamically typed. Additionally, it has control capabilities and integration features that can make applications more productive.\n\nDisadvantages of Python\n\nWhile Python is arguably one of the easiest and fastest languages to learn, it’s also decidedly slower to execute because it’s a dynamically typed, interpreted language, executed line-by-line. Python does extra work while executing the code, making it less suitable for use in projects that depend on speed. However, if speed isn’t a sensitive issue, Python’s slower nature won’t likely be a problem.\n\nOther potential disadvantages include:\n\n(1) It only executes one thread at a time: Python has a Global Interpreter Lock that only lets one thread execute at a time, so if you're working on a multi-threaded CPU-bound program, it'll likely be even slower. Using multiprocessing programs instead of multithreaded programs can be an effective workaround.\n\n(2) It isn't mobile native: Python can be effectively and easily used for mobile purposes, but you'll need to put a bit more effort into finding libraries that give you the necessary framework. Some examples include Kivy, which lets you use the same API to create mobile apps and software that you can run on Raspberry PI, Linux, and Windows.\n\n(3) It uses a large amount of memory: If you're working on a project where many objects are active in RAM, this could present an issue for you. Switching to NumPy could be an effective workaround to reduce the amount of memory Python uses for each object.",

Though some simple metalworking of malleable metals, particularly the use of gold and copper for purposes of ornamentation, was known in the Stone Age, it is the melting and smelting of copper that marks the end of the Stone Age. In Western Asia, this occurred by about 3,000 BC, when bronze became widespread. The term Bronze Age is used to describe the period that followed the Stone Age, as well as to describe cultures that had developed techniques and technologies for working copper alloys (bronze: originally copper and arsenic, later copper and tin) into tools, supplanting stone in many uses.\n\nStone Age artifacts that have been discovered include tools used by modern humans, by their predecessor species in the genus Homo, and possibly by the earlier partly contemporaneous genera Australopithecus and Paranthropus. Bone tools have been discovered that were used during this period as well but these are rarely preserved in the archaeological record.

        "evidence": "We identified 5 common models in previous work primarily intended for learned classifiers rather than hand-crafted rules. We adapt these models to a multi-label hierarchical classification task by training a series of one-vs-all binary classifiers BIBREF34 , one for each label in the taxonomy. With the exception of the CNN and BERT models, following previous work BIBREF19 , BIBREF3 , BIBREF8 we make use of an SVM classifier using the LIBSvM framework BIBREF35 with a linear kernel. Models are trained and evaluated from coarse to fine levels of taxonomic specificity. At each level of taxonomic evaluation, a set of non-overlapping confidence scores for each binary classifier are generated and sorted to produce a list of ranked label predictions. We evaluate these ranks using Mean Average Precision BIBREF36 . ARC questions are evaluated using the standard 3,370 questions for training, 869 for development, and 3,548 for testing.\nN-grams, POS, Hierarchical features: A baseline bag-of-words model incorporating both tagged and untagged unigrams and bigams. We also implement the hierarchical classification feature of Li and Roth BIBREF6 , where for a given question, the output of the classifier at coarser levels of granularity serves as input to the classifier at the current level of granularity.\nDependencies: Bigrams of Stanford dependencies BIBREF37 . For each word, we create one unlabeled bigram for each outgoing link from that word to it's dependency BIBREF20 , BIBREF3 .\nQuestion Expansion with Hypernyms: We perform hypernym expansion BIBREF22 , BIBREF19 , BIBREF3 by including WordNet hypernyms BIBREF38 for the root dependency word, and words on it's direct outgoing links. WordNet sense is identified using Lesk word-sense disambiguation BIBREF39 , using question text for context. We implement the heuristic of Van-tu et al. BIBREF24 , where more distant hypernyms receive less weight.\nEssential Terms: Though not previously reported for QC, we make use of unigrams of keywords extracted using the Science Exam Essential Term Extractor of Khashabi et al. BIBREF26 . For each keyword, we create one binary unigram feature.\nCNN: Kim BIBREF28 demonstrated near state-of-the-art performance on a number of sentence classification tasks (including TREC question classification) by using pre-trained word embeddings BIBREF40 as feature extractors in a CNN model. Lei et al. BIBREF29 showed that 10 CNN variants perform within +/-2% of Kim's BIBREF28 model on TREC QC. We report performance of our best CNN model based on the MP-CNN architecture of Rao et al. BIBREF41 , which works to establish the similarity between question text and the definition text of the question classes. We adapt the MP-CNN model, which uses a “Siamese” structure BIBREF33 , to create separate representations for both the question and the question class. The model then makes use of a triple ranking loss function to minimize the distance between the representations of questions and the correct class while simultaneously maximising the distance between questions and incorrect classes. We optimize the network using the method of Tu BIBREF42 .\nBERT-QC (This work): We make use of BERT BIBREF43 , a language model using bidirectional encoder representations from transformers, in a sentence-classification configuration. As the original settings of BERT do not support multi-label classification scenarios, and training a series of 406 binary classifiers would be computationally expensive, we use the duplication method of Tsoumakas et al. BIBREF34 where we enumerate multi-label questions as multiple single-label instances during training by duplicating question text, and assigning each instance one of the multiple labels. Evaluation follows the standard procedure where we generate a list of ranked class predictions based on class probabilities, and use this to calculate Mean Average Precision (MAP) and Precision@1 (P@1). As shown in Table TABREF7 , this BERT-QC model achieves our best question classification performance, significantly exceeding baseline performance on ARC by 0.12 MAP and 13.5% P@1.\nWith the exception of the CNN and BERT models, following previous work (e.g. Silva et al., 2011; Roberts et al., 2014; Xia et al., 2018) we make use of an SVM classifier using the LIBSvM framework (Chang and Lin, 2011) with a linear kernel.",

These issues are further exacerbated in areas where space is a premium (as frequent on social media platforms), often leading to usage and development of shorthand, in-jokes, and self-reference. Thus, building a system to classify the humor of tweets is a difficult task. However, with transfer-learning and the Fast.ai library, we can build a high quality classifier in a foreign language.

        "answer": "Jubilee was created by writer Chris Claremont and artist Marc Silvestri and first appeared in The Uncanny X-Men #244 (May 1989). Claremont had earlier introduced a \"Jubilee\" of sorts in The New Mutants Annual #2 (1986). In that story, Darla of the Fat Boys, after being mentally and biologically warped, uses identical powers to those of the later Jubilation Lee and introduces herself as \"Jubilee! Whose every move is a celebration!\" In her first appearance Jubilation Lee gives a similar self-introduction: \"Actually, my name is Jubilee! 'Cause with me, every day's a celebration!\" Darla is returned to normal by the end of The New Mutants Annual #2, and no in-story connection between the characters is ever established.\n\nJubilee appeared regularly as an X-Men team member in The Uncanny X-Men through issue #280 (Sept. 1991), and later was a staple of X-Men (1991) as a member of the X-Men's Blue Team. During the same timeframe, she also served as Wolverine's sidekick in Wolverine vol. 2 #40–75 (1991–1993).\n\nAfter the Phalanx Covenant storyline in X-Men #16–17 and The Uncanny X-Men #316–317, Jubilee, who was then a teenager, was transferred to the X-Men trainee squad Generation X and starred in the entire run of Generation X #1–75 (1994–2001). After the dissolution of Generation X, Jubilee returned to the pages of The Uncanny X-Men, first as a member of the X-Corporation (#403–406, 2002), and later as a team member in her own right (#423–437, 2003–2004). Jubilee had a six-issue self-titled limited series in 2004 written by Robert Kirkman, but loses her mutant powers in House of M – The Day After #1 (Jan. 2006). She then adopts the alias Wondra and joins the reconstituted New Warriors in New Warriors vol. 4 #1–20 (2007–2009).\n\nJubilee is affected with vampirism during the \"Curse of the Mutants\" in X-Men vol. 3 #1 (July 2010) and remained a sporadic character on that title through issue #27 (April 2012), as well as a supporting character in X-23 vol. 3 (2010–2011). In 2011, she saw print in her second four issue limited series, Wolverine and Jubilee written by Kathryn Immonen and drawn by Phil Noto, as an aftermath follow-up to the Curse of the Mutants storyline. Jubilee later featured as a regular character in the all-female X-Men vol. 4 #1–25 (2013–2015), and as a supporting character in Patsy Walker, a.k.a. Hellcat! (2016).

        "evidence": "Natural hydrogen (known as white hydrogen), is naturally occurring molecular hydrogen on or in Earth (as opposed to hydrogen produced in the laboratory or in industry). The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources, and from grey, brown or black hydrogen, which is obtained from fossil sources or from the electrolysis of water. Natural hydrogen may be renewable, non-polluting and allows for lower cost operation compared to industrial hydrogen. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.\n\nOrigin of natural hydrogen\nThere are several sources of natural hydrogen:\n\n- degassing of deep hydrogen from the Earth's crust and mantle;\n- reaction of water with ultrabasic rocks (serpentinisation);\n- contact of water with reducing agents in the Earth's mantle;\n- interaction of water with freshly exposed rock surfaces (weathering);\n- decomposition of hydroxyl ions in the structure of minerals;\n- Natural radiolysis of water;\n- decomposition of organic matter;\n- biological activity\n- Extraction\n- Natural hydrogen is extracted from wells, mixed with other gases such as nitrogen or helium.\n\nSeveral sources have been identified in France. Geologists Alain Prinzhofer and Eric Derville have demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States. However, their potential remains difficult to assess.\n\nNumerous emanations on the ocean floor have been identified but are difficult to exploit. The discovery of a significant emergence in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.\n\nGeology\nNatural hydrogen is generated continuously from a variety of natural sources. There are many known hydrogen emergences on mid-ocean ridges. Another of the known reactions, serpentinisation, occurs under the sea floor (in the oceanic crust).\n\nDiagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably in Russia. Other sources are being explored, such as mantle hydrogen, or hydrogen from radiolysis (natural electrolysis) or from bacterial activity. In France, the Alps and Pyrenees are suitable for exploitation. New Caledonia has hyperalkaline sources that show dihydrogen emissions. A large accumulation of natural hydrogen was discovered in Bourakebougou (Mali).\n\nCharacteristics\nDihydrogen is very soluble in fresh water, especially at depth (solubility increases with pressure).\n\nhttps://en.wikipedia.org/wiki/Natural_hydrogen",

        "evidence": "The Flickr30K dataset BIBREF0 is a collection of over 30,000 images with 5 crowdsourced descriptions each. It is commonly used to train and evaluate neural network models that generate image descriptions (e.g. BIBREF2 ). An untested assumption behind the dataset is that the descriptions are based on the images, and nothing else. Here are the authors (about the Flickr8K dataset, a subset of Flickr30K):\n“By asking people to describe the people, objects, scenes and activities that are shown in a picture without giving them any further information about the context in which the picture was taken, we were able to obtain conceptual descriptions that focus only on the information that can be obtained from the image alone.” BIBREF1 \nWhat this assumption overlooks is the amount of interpretation or recontextualization carried out by the annotators. Let us take a concrete example. Figure FIGREF1 shows an image from the Flickr30K dataset.\nThis image comes with the five descriptions below. All but the first one contain information that cannot come from the image alone. Relevant parts are highlighted in bold:\nWe need to understand that the descriptions in the Flickr30K dataset are subjective descriptions of events. This can be a good thing: the descriptions tell us what are the salient parts of each image to the average human annotator. So the two humans in Figure FIGREF1 are relevant, but the two soap dispensers are not. But subjectivity can also result in stereotypical descriptions, in this case suggesting that the male is more likely to be the manager, and the female is more likely to be the subordinate. rashtchian2010collecting do note that some descriptions are speculative in nature, which they say hurts the accuracy and the consistency of the descriptions. But the problem is not with the lack of consistency here. Quite the contrary: the problem is that stereotypes may be pervasive enough for the data to be consistently biased. And so language models trained on this data may propagate harmful stereotypes, such as the idea that women are less suited for leadership positions.\nThis paper aims to give an overview of linguistic bias and unwarranted inferences resulting from stereotypes and prejudices. I will build on earlier work on linguistic bias in general BIBREF3 , providing examples from the Flickr30K data, and present a taxonomy of unwarranted inferences. Finally, I will discuss several methods to analyze the data in order to detect biases.\nAn untested assumption behind the dataset is that the descriptions are based on the images, and nothing else.",

In this paper, we pre-train three sentiment classifiers: BiLSTM, BiLSTM$+$A, and CNN. These classifiers are targeted by white-box attacking methods to generate adversarial examples (detailed in Section SECREF9). BiLSTM is composed of an embedding layer that maps individual words to pre-trained word embeddings; a number of bi-directional LSTMs that capture sequential contexts; and an output layer that maps the averaged LSTM hidden states to a binary output. BiLSTM$+$A is similar to BiLSTM except it has an extra self-attention layer which learns to attend to salient words for sentiment classification, and we compute a weighted mean of the LSTM hidden states prior to the output layer. Manual inspection of the attention weights show that polarity words such as awesome and disappointed are assigned with higher weights. Finally, CNN has a number of convolutional filters of varying sizes, and their outputs are concatenated, pooled and fed to a fully-connected layer followed by a binary output layer.\nRecent development in transformer-based pre-trained models have produced state-of-the-art performance on a range of NLP tasks BIBREF17, BIBREF18. To validate the transferability of the attacking methods, we also fine-tune a BERT classifier for black-box tests.

We focus on three main issues, including, how to incorporate affective information into chatbots, what are resources that available and can be used to build EAC, and how to evaluate EAC performance. The rise of EAC was started by Parry, which uses a simple rule-based approach. Now, most of EAC are built by using a neural-based approach, by exploiting emotion classifier to detect emotion contained in the text. In the modern era, the development of EAC gains more attention since Emotion Generation Challenge shared task on NLPCC 2017. In this era, most EAC is developed by adopting encoder-decoder architecture with sequence-to-sequence learning. Some variant of the recurrent neural network is used in the learning process, including long-short-term memory (LSTM) and gated recurrent unit (GRU). There are also some datasets available for developing EAC now. However, the datasets are only available in English and Chinese. These datasets are gathered from various sources, including social media, online website and manual construction by crowdsourcing. Overall, the difference between these datasets and the common datasets for building chatbot is the presence of an emotion label. In addition, we also investigate the available affective resources which usually use in the emotion classification task. In this part, we only focus on English resources and found several resources from the old one such as LIWC and Emolex to the new one, including DepecheMood and EmoWordNet. In the final part, we gather information about how to evaluate the performance of EAC, and we can classify the approach into two techniques, including qualitative and quantitative assessment. For qualitative assessment, most studies used ISO 9241, which covers several aspects such as efficiency, effectiveness, and satisfaction. While in quantitative analysis, two techniques can be used, including automatic evaluation (by using perplexity) and manual evaluation (involving human judgement). Overall, we can see that effort to humanize chatbots by incorporation affective aspect is becoming the hot topic now. We also predict that this development will continue by going into multilingual perspective since up to now every chatbot only focusing on one language. Also, we think that in the future the studies of humanizing chatbot are not only utilized emotion information but will also focus on a contextual-aware chatbot.\nWe focus on three main issues, including, how to incorporate affective information into chatbots, what are resources that available and can be used to build EAC, and how to evaluate EAC performance.",

        "question": "Why the evaluation metric is proposed?",
        "answer": "Aims to overcome the limitation of high lexical dependence in Rouge.",
        "evidence": "Automatic text summarization has been an active research area in natural language processing for several decades. To compare and evaluate the performance of different summarization systems, the most intuitive approach is assessing the quality of the summaries by human evaluators. However, manual evaluation is expensive and the obtained results are subjective and difficult to reproduce BIBREF0 . To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nWe then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge.",

        "question": "What is the main difference between a nuclear bomb and a nuclear power generator?",
        "evidence": "Nuclear fission is a kind of nuclear reaction. It is when an atom splits apart into smaller atoms. Some fission reactions give off a lot of energy, and are used in nuclear weapons and nuclear reactors. Nuclear fission was discovered in December 1938 by the German nuclear chemist Otto Hahn and his assistant Fritz Strassmann in Berlin.\n\nAn atom is the smallest particle which makes up a chemical element (e.g. hydrogen, oxygen, magnesium). All atoms are very small. Atoms are made of three components or particles: Protons, neutrons and electrons. The protons and neutrons are clumped together in a ball called a nucleus, at the center of every atom. The electrons orbit around the nucleus in its 'electron cloud'. Elements which have large nuclei, such as uranium and plutonium, can be made to fission.\n\nIf a (relatively) very large atomic nucleus is hit by a slow-moving neutron, it will sometimes become unstable and break into two nuclei. When the nucleus breaks apart (or fissions) it releases energy, mostly as gamma rays and heat. It also causes some neutrons to be released from the nucleus.\n\nFor a few isotopes (an atom with the same amount of protons but a different amount of neutrons) such fission can release many neutrons. If those neutrons then hit other atoms, they will make the other atoms split. This can happen again and again. This is called a nuclear chain-reaction, and it can release huge amounts of energy.\n\nIn a nuclear bomb, this must happen very quickly to make a very big explosion. The amount of energy released in the explosion is measured in kilotons. One kiloton is the same as the energy of one thousand tons of TNT (trinitrotoluene).\n\nIn a nuclear reactor this must happen slowly to make heat. The heat is used to boil water into steam, which turns a steam turbine to generate electricity.",

        "evidence": "Sunset, also known as sundown, is the daily disappearance of the Sun below the horizon due to Earth's rotation. As viewed from everywhere on Earth (except the North and South poles), the equinox Sun sets due west at the moment of both the spring and autumn equinoxes. As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere.\nThe time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed.\nSunset is distinct from twilight, which is divided into three stages. The first one is civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon. The second phase is nautical twilight, between 6 and 12 degrees below the horizon. The third phase is astronomical twilight, which is the period when the Sun is between 12 and 18 degrees below the horizon. Dusk is at the very end of astronomical twilight, and is the darkest moment of twilight just before night. Finally, night occurs when the Sun reaches 18 degrees below the horizon and no longer illuminates the sky.\nLocations further north than the Arctic Circle and further south than the Antarctic Circle experience no full sunset or sunrise on at least one day of the year, when the polar day or the polar night persists continuously for 24 hours.",

        "question": "What disease do they detect in their paper?",

        "evidence": "Recent advances in Machine Learning (ML) and, in particular, in Deep Neural Networks (DNN) have allowed the development of highly accurate predictive systems for numerous applications. Among others, health has received significant attention due to the potential of ML-based diagnostic, monitoring and therapeutic systems, which are fast (when compared to traditional diagnostic processes), easily distributed and cheap to implement (many such systems can be executed in mobile devices). Furthermore, these systems can incorporate biometric data to perform non-invasive diagnostics.\nAmong other data types, speech has been proposed as a valuable biomarker for the detection of a myriad of diseases, including: neurological conditions, such as Alzheimer’s BIBREF0, Parkinson’s disease (PD) BIBREF1 and Amyotrophic Lateral Sclerosis BIBREF2; mood disorders, such as depression, anxiety BIBREF3 and bipolar disorder BIBREF4; respiratory diseases, such as obstructive sleep apnea (OSA) BIBREF5. However, temporal and financial constraints, lack of awareness in the medical community, ethical issues and patient-privacy laws make the acquisition of medical data one of the greatest obstacles to the development of health-related speech-based classifiers, particularly for deep learning models. For this reason, most systems rely on knowledge-based (KB) features, carefully designed and selected to model disease symptoms, in combination with simple machine learning models (e.g. Linear classifiers, Support Vector Machines). KB features may not encompass subtler symptoms of the disease, nor be general enough to cover varying levels of severity of the disease. To overcome this limitation, some works have instead focused on speaker representation models, such as Gaussian Supervectors and i-vectors. For instance, Garcia et al. BIBREF1 proposed the use of i-vectors for PD classification and Laaridh et al. BIBREF6 applied the i-vector paradigm to the automatic prediction of several dysarthric speech evaluation metrics like intelligibility, severity, and articulation impairment. The intuition behind the use of these representations is the fact that these algorithms model speaker variability, which should include disease symptoms BIBREF1.\nProposed by Snyder et al., x-vectors are discriminative deep neural network-based speaker embeddings, that have outperformed i-vectors in tasks such as speaker and language recognition BIBREF7, BIBREF8, BIBREF9. Even though it may not be evident that discriminative data representations are suitable for disease detection when trained with general datasets (that do not necessarily include diseased patients), recent works have shown otherwise. X-vectors have been successfully applied to paralinguistic tasks such as emotion recognition BIBREF10, age and gender classification BIBREF11, the detection of obstructive sleep apnea BIBREF12 and as a complement to the detection of Alzheimer's Disease BIBREF0. Following this line of research, in this work we study the hypothesis that speaker characteristics embedded in x-vectors extracted from a single network, trained for speaker identification using general data, contain sufficient information to allow the detection of multiple diseases. Moreover, we aim to assess if this information is kept even when language mismatch is present, as has already been shown to be true for speaker recognition BIBREF8. In particular, we use the x-vector model as a feature extractor, to train Support Vector Machines for the detection of two speech-affecting diseases: Parkinson's disease (PD) and obstructive sleep apnea (OSA).\nPD is the second most common neurodegenerative disorder of mid-to-late life after Alzheimer’s disease BIBREF13, affecting 1% of people over the age of 65. Common symptoms include bradykinesia (slowness or difficulty to perform movements), muscular rigidity, rest tremor, as well as postural and gait impairment. 89% of PD patients develop also speech disorders, typically hypokinetic dysarthria, which translates into symptoms such as reduced loudness, monoloudness, monopitch, hypotonicity, breathy and hoarse voice quality, and imprecise articulation BIBREF14BIBREF15.\nOSA is a sleep-concerned breathing disorder characterized by a complete stop or decrease of the airflow, despite continued or increased inspiratory efforts BIBREF16. This disorder has a prevalence that ranges from 9% to 38% through different populations BIBREF17, with higher incidence in male and elderly groups. OSA causes mood and personality changes, depression, cognitive impairment, excessive daytime sleepiness, thus reducing the patients' quality of life BIBREF18, BIBREF19. It is also associated with diabetes, hypertension and cardiovascular diseases BIBREF16, BIBREF20. Moreover, undiagnosed sleep apnea can have a serious economic impact, having had an estimated cost of $\\$150$ billion in the U.S, in 2015 BIBREF21. Considering the prevalence and serious nature of the two diseases described above, speech-based technology that tests for their existence has the potential to become a key tool for early detection, monitoring and prevention of these conditions BIBREF22.\nThe remainder of this document is organized as follows. Section SECREF2 presents the background concepts on speaker embeddings, and in particular on x-vectors. Section SECREF3 introduces the experimental setup: the corpora, the tasks, the KB features and the speaker embeddings employed. The results are presented and discussed in section SECREF4. Finally, section SECREF5 summarizes the main conclusions and suggests possible directions for future work.\nIn particular, we use the x-vector model as a feature extractor, to train Support Vector Machines for the detection of two speech-affecting diseases: Parkinson's disease (PD) and obstructive sleep apnea (OSA).",

        "evidence": "We aimed to mimic the presence of sparse/noisy content distribution, mandating the need to curate a novel dataset via specific lexicons. We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation.

        "question": "What is the best time of year to visit Lake Tahoe?",
        "evidence": "",
        "answer": "The best time to visit Lake Tahoe?  The answer depends on your interests (or possibly the interests of the person advising you).   \n\nSnow lovers:  if you count down the days until the mountain resorts open up, Winter is the time for you.  Most resorts open around Thanksgiving and typically close in mid-late Spring.  Tahoe has several world-class ski resorts; with Northstar and Palisades being favorites on the North shore, and Heavenly Mountain being the favorite on the South Shore.   If flying down the mountain isn't appealing, you can go sledding, snowshoeing or snowmobiling.  The snow capped mountains reflected on the deep blue waters of Tahoe make for epic winter sights.  There's plenty of joy to be had staying inside, cozying up by the fireplace and simply enjoying the peaceful scenery outside your windows.   \n\nSun Lovers:  Tahoe Summers are for you.  The Lake: beaches, marinas, restaurants, music and people galore.   The lakeside vibe on Tahoe's beaches is casual and fun.  Boaters & sailors highly regard Tahoe's famous blue waters.  Tahoe is a kayaker's paradise with so many stunning coves to explore.  Venture over to Emerald Bay to see where the lake turns from blue to green & visit the historic island in the middle.   Hikers and cyclists; when the snow melts, there are countless trails to explore, including long segments of the famous Pacific Rim trail.  For those who prefer leisurely strolls, there are some spectacular walking paths right along the lake.   Floating down the Truckee River is a must-do for a frolicking day of fun. Campers love Tahoe as well, with many fun campgrounds to visit; some even within a short distance to the bustling streets of Stateline South Shore, where there are casinos, restaurants and music venues.  Golfers can rejoice on the world class course along the lake at Edgewood.  \n\nIn the transition months, the scenery is equally beautiful; and the tourist crowds are much smaller.  Some people favorite the Spring and Fall in Tahoe, simply for a more secluded, scenic mountain getaway; catching either the tail end of the snow season or the early warmth glimpses of Summer. \n\nTahoe is a year-round destination.  The best time to visit truly depends on the type of getaway you're seeking.  My recommendation: Try all 4 seasons; you may find that it's impossible to pick a favorite!",

Our system, though, performs well in this case also.\nSentence 3 presents a false-negative case where it was hard for even humans to get the sarcasm. This is why our gaze features (and subsequently the complete set of features) account for erroneous prediction.\nIn sentence 4, gaze features alone false-indicate presence of incongruity, whereas the system predicts correctly when gaze and linguistic features are taken together.\nFrom these examples, it can be inferred that, only gaze features would not have sufficed to rule out the possibility of detecting other forms of incongruity that do not result in sarcasm.\nExample sentence 1 is sarcastic, and requires extra-linguistic knowledge (about poor living conditions at Manchester).",

First released in 1985 as an extension of the C programming language, it has since expanded significantly over time; modern C++ currently has object-oriented, generic, and functional features, in addition to facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Embarcadero, Oracle, and IBM.\n\nC++ was designed with systems programming and embedded, resource-constrained software and large systems in mind, with performance, efficiency, and flexibility of use as its design highlights. C++ has also been found useful in many other contexts, with key strengths being software infrastructure and resource-constrained applications, including desktop applications, video games, servers (e.g. e-commerce, web search, or databases), and performance-critical applications (e.g. telephone switches or space probes).\n\nC++ is standardized by the International Organization for Standardization (ISO), with the latest standard version ratified and published by ISO in December 2020 as ISO/IEC 14882:2020 (informally known as C++20).

        "question": "How popular were figs in ancient Rome?",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

        "answer": "Arabic, Chinese, English, French, and German.",
        "evidence": "Categories such as animal or furniture are fundamental cognitive building blocks allowing humans to efficiently represent and communicate the complex world around them. Concepts (e.g., dog, table) are grouped into categories based on shared properties pertaining, for example, to their behavior, appearance, or function. Categorization underlies other cognitive functions such as perception BIBREF0 , BIBREF1 or language BIBREF2 , BIBREF3 , and there is evidence that categories are not only shaped by the world they represent, but also by the language through which they are communicated BIBREF4 , BIBREF5 . Although mental categories exist across communities and cultures, their exact manifestations differ BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . For example, American English speakers prefer taxonomic categorizations (e.g., mouse,squirrel) while Chinese speakers tend to prefer to categorize objects relationally (e.g., tree, squirrel; BIBREF7 ).\nGiven their prevalent function in human cognition, the acquisition and representation of categories has attracted considerable attention in cognitive science, and numerous theories have emerged BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . Empirical studies of category acquisition and representation, have been predominantly based on small-scale laboratory experiments. In a typical experiment, human subjects are presented with small sets of often artificial concepts, such as binary strings BIBREF14 or colored shapes BIBREF15 , with strictly controlled features BIBREF16 , BIBREF17 , BIBREF18 . Hypotheses and principles of human categorization are established based on the processes and characteristics of the categorizations produced by the participants. The distribution of subjects participating in such studies is often skewed towards members of cultural and socioeconomic groups which are prevalent in the environment where the research is conducted, and typically consists to a large proportion of western, educated, wealthy and English-speaking participants often sampled from the even more specific population of college students. The demographic and socioeconomic bias has been long recognized, and the question of how this bias might impact conclusions about human cognition in general BIBREF19 and category learning specifically is under active debate BIBREF9 . Although laboratory studies are invaluable for understanding categorization phenomena in a controlled environment, they are also expensive and time-consuming to conduct, and consequently problematic to scale.\nIn this work, we scale the investigation of category learning and representation along two axes: (1) the complexity of the learning environment, and consequently the richness of learnable concept and category representations, and (2) the diversity of languages and cultures considered in evaluation. We present a novel knowledge-lean, cognitively motivated Bayesian model which learns categories and their structured features jointly from large natural language text corpora in five diverse languages: Arabic, Chinese, English, French, and German. We approximate the learning environment using large corpora of natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Besides text corpora can cover arbitrarily semantically complex domains, and are available across languages, providing an ideal test environment for studying categorization at scale.\nFigure 1 illustrates example input to our model, and Figure 2 shows example categories and associated features as induced by our model from the English Wikipedia. Following prior work BIBREF21 , BIBREF22 , we create language-specific sets of stimuli, each consisting of a mention of target concept (e.g., apple), within its local linguistic context (e.g., {contains, seeds}; cf., Figure 1 ). We consider each stimulus an observation of the concept, i.e., the word referring to the concept is an instance of the concept itself, and its context words are a representation of its features. Our model infers categories as groups of concepts occurring with similar features; and it infers feature types as groups of features which co-occur with each other. The output of our model (cf., Figure 2 ) are categories as clusters of concepts, each associated with a set of feature types, i.e., thematically coherent groups of features. We train a separate model on each of our target languages, each time presenting the model with input stimuli from the relevant language.\nComputational models in general, and Bayesian models in particular, allow to investigate hypotheses about cognitive phenomena by systematically modifying the learning mechanism or available input while observing the learning outcome. Bayesian models have been applied to a variety of cognitive phenomena BIBREF23 , BIBREF24 , BIBREF25 , and category acquisition is no exception. Following from Anderson's BIBREF14 , BIBREF26 , BIBREF27 seminal work, a number of models have been developed, and tested in their ability to reproduce human behavior in laboratory settings by exposing the models to small sets of controlled inputs with restricted features. In this work we draw on the full potential of computational modeling by exposing our models to (a) more complex data reflecting the diversity of contexts in which concepts can be observed; and (b) a input data in different languages, shedding light on the applicability of computational cognitive models beyond the prevalent English test language.\nCategorization tasks in a laboratory environment typically involve stimuli with a small set of features which are relevant to the categorization target, eliminating the need to detect features, and discriminate them in their relevance. In the real world, however, concepts are observed in contexts and a substantial part of acquiring categorical knowledge involves learning which features are useful to discriminate among concepts. In fact, research has shown that humans learn features jointly with categories BIBREF28 , BIBREF29 and that these features are themselves structured so as to represent the diversity and complexity of the properties exhibited in the world BIBREF30 , BIBREF31 , BIBREF32 . Our novel model of category learning presented in this article, jointly learns categories and their structured features from large sets of informationally rich data.\nOur work exemplifies the opportunities that arise from computational models and large data sets for investigating the mechanisms with which conceptual representations emerge, as well as the representations themselves in a broader context. We simulate the acquisition of categories comprising hundreds of concepts by approximating the learning environment with natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , as well as human-like biases BIBREF33 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Text corpora are a prime example of naturally occurring large-scale data sets BIBREF34 , BIBREF35 , BIBREF36 . In analogy to real-world situations, they encapsulate rich, diverse, and potentially noisy, information. The wide availability of corpora allows us to train and evaluate cognitive models on data from diverse languages and cultures. We test our model on corpora from five languages, derived from the online encyclopedia Wikipedia in Arabic, Chinese, French, English, and German. Wikipedia is a valuable resource for our study because it (a) discusses concepts and their properties explicitly and can thus serve as a proxy for the environment speakers of a language are exposed to; and (b) allows us to construct corpora which are highly comparable in their content across languages, controlling for effects of genre or style.\nWe present a series of evaluations investigating the quality of the induced categories and features. Leveraging a reference comprising hundreds of concepts and more than 30 categories, we demonstrate that our model learns meaningful categories in all five target languages. We furthermore show, through crowd-sourced evaluations involving native speakers of each target language, that the induced feature types are (a) each thematically coherent and interpretable; and (b) are associated with categories in comprehensible ways. We discuss language-specific idiosyncrasies emerging from the induced representations.\nIn the remainder of this article, we first review related literature, before we present a cognitively motivated model for learning categories and their structured representations from large natural language corpora. We then evaluate the quality of the emerging representations, as well as the generalizability of our model across languages. Note that the primary goal of this work is not to characterize differences in categories and features arising from different languages (even though this would be an interesting avenue for future work). Rather, we aim to demonstrate the utility of large-scale naturalistic datasets for cognitive modeling, and to verify mechanisms of categorization known from laboratory studies at scale and across communities.\nWe present a novel knowledge-lean, cognitively motivated Bayesian model which learns categories and their structured features jointly from large natural language text corpora in five diverse languages: Arabic, Chinese, English, French, and German.",

        "answer": "Both deep and contextualized.",
        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized.",

However, in preliminary experiments we found that BERT performs very poorly at predicting the acceptability of adversarial examples (e.g. it predicts word-salad-like sentences generated by FGVM as very acceptable), revealing the brittleness of these supervised models. We next explore an unsupervised approach BIBREF22, BIBREF23, using normalised sentence probabilities estimated by pre-trained language models for measuring acceptability. In the original papers, the authors tested simple recurrent language models; here we use modern pre-trained language models such as GPT-2 BIBREF24 and XLNet BIBREF18. Our final acceptability metric (ACPT) is based on normalised XLNet sentence probabilities: ${\\log P(s)} / ({((5+|s|)/(5+1))^\\alpha })$, where $s$ is the sentence, and $\\alpha $ is a hyper-parameter (set to 0.8) to dampen the impact of large values BIBREF25.\nWe only computed BLEU and ACPT scores for adversarial examples that have successfully fooled the classifier. Our rationale is that unsuccessful examples can artificially boost these scores by not making any modifications, and so the better approach is to only consider successful examples.\nAs sentiment classification is our target task, we use the standard classification accuracy (ACC, the lower the better) to evaluate the attacking performance of adversarial examples (criterion (a)).",

Given a set of training examples, each marked as belonging to one of two categories, an SVM training algorithm builds a model that assigns new examples to one category or the other, making it a non-probabilistic binary linear classifier (although methods such as Platt scaling exist to use SVM in a probabilistic classification setting). SVM maps training examples to points in space so as to maximise the width of the gap between the two categories. New examples are then mapped into that same space and predicted to belong to a category based on which side of the gap they fall.\n\nIn addition to performing linear classification, SVMs can efficiently perform a non-linear classification using what is called the kernel trick, implicitly mapping their inputs into high-dimensional feature spaces.\n\nThe support vector clustering algorithm, created by Hava Siegelmann and Vladimir Vapnik, applies the statistics of support vectors, developed in the support vector machines algorithm, to categorize unlabeled data.[citation needed] These data sets require unsupervised learning approaches, which attempt to find natural clustering of the data to groups and, then, to map new data according to these clusters.",

        "evidence": "",
        "answer": "I argue that differences in outcomes of credit scoring constitute both a data issue and an algorithmic bias. Let’s first examine the bias in the dataset. I think of the model itself as a black box that generates outputs to fulfill certain objectives – in the case of credit scoring, the objective is the accuracy, recall, and precision of default risk predictions. The model at its untrained version does not discriminate against foreign workers, women, or young people: in fact, it does not conceive of these (socially constructed) labels the way humans do. Yet, the dataset that the model is trained on is fraught with socially constructed biases. For example, social norms cast women as incapable, foreign workers as untrustworthy, and young people as inexperienced, leading to higher unemployment rate and worse living conditions for these groups. Their resulting higher historical default likelihood stems less likely from the demographics-related differences in capability than from the vicious cycles generated by social stereotypes. Stereotypes render datasets biased, which in turns bias the algorithms: given the goal to maximize prediction accuracy, the model learns the “patterns” in the dataset and absorbs the socially constructed differences as a part of its prediction algorithm. Can we blame the algorithm? – After all, the model is constrained to the “history” and has no imaginative capacity for the potential of the historically discriminated groups. Essentially we have a “garbage in, garbage out” scenario caused by the historical and representation biases in the data inputs.\n\nOn the other hand, I argue that the outcome differences still constitute an algorithmic bias. I believe that we could still “blame” the model for the objectives and constraints that it has to fulfill (even though we humans lay them down in the first place). As illustrated above, with accuracy as the evaluation metric, the entire prediction/forecast algorithm built on historical datasets is meant to repeat the history without looking for potential or discerning social norms. Does the objective of maximizing accuracy constitute a bias itself? – If we can discern the vicious cycle that is both created by and reifying the socially crafted myths (weak women, reckless youth, and xenophobia), a model that actively learns and propagates certain kinds of societal stereotype should certainly be called out for its bias! However, we hard-wire the models to optimize those goals, and to address the inherent bias in the metrics, we humans are responsible for modifying the objectives and adding appropriate constraints. For example, in the programming assignment we encounter the mitigation technique that rejects predictions within a certain decision boundary. Besides techniques like active rejection, can we add constraints such as promoting the growth of underprivileged groups as an objective? Without these constraints, I would say the outcome differences also constitute an algorithmic bias in the part of objective specification.",

        "question": "Are they the first to explore features related to the users tendency in hatred content that used a deep learning model?",
        "answer": "Yes.",
        "evidence": "Social media is a very popular way for people to express their opinions publicly and to interact with others online. In aggregation, social media can provide a reflection of public sentiment on various events. Unfortunately, many users engaging online, either on social media, forums or blogs, will often have the risk of being targeted or harassed via abusive language, which may severely impact their online experience and the community in general. The existence of social networking services creates the need for detecting user-generated hateful messages prior to publication. All published text that is used to express hatred towards some particular group with the intention to humiliate its members is considered a hateful message.\nAlthough hate speech is protected under the free speech provisions in the United States, there are other countries, such as Canada, France, United Kingdom, and Germany, where there are laws prohibiting it as being promoting violence or social disorder. Social media services such as Facebook and Twitter have been criticized for not having done enough to prohibit the use of their services for attacking people belonging to some specific race, minority etc. BIBREF0 . They have announced though that they would seek to battle against racism and xenophobia BIBREF1 . Nevertheless, the current solutions deployed by them have attempted to address the problem with manual effort, relying on users to report offensive comments BIBREF2 . This not only requires a huge effort by human annotators, but it also has the risk of applying discrimination under subjective judgment. Moreover, a non-automated task by human annotators would have strong impact on system response times, since a computer-based solution can accomplish this task much faster than humans. The massive rise in the user-generated content in the above social media services, with manual filtering not being scalable, highlights the need for automating the process of on-line hate-speech detection.\nDespite the fact that the majority of the solutions for automated detection of offensive text rely on Natural Language Processing (NLP) approaches, there is lately a tendency towards employing pure machine learning techniques like neural networks for that task. NLP approaches have the drawback of being complex, and to a large extent dependent on the language used in the text. This provides a strong motivation for employing alternative machine learning models for the classification task. Moreover, the majority of the existing automated approaches depend on using pre-trained vectors (e.g. Glove, Word2Vec) as word embeddings to achieve good performance from the classification model. That makes the detection of hatred content unfeasible in cases where users have deliberately obfuscated their offensive terms with short slang words.\nThere is a plethora of unsupervised learning models in the existing literature to deal with hate-speech BIBREF3 , as well as in detecting the sentiment polarity in tweets BIBREF4 . At the same time, the supervised learning approaches have not been explored adequately so far. While the task of sentence classification seems similar to that of sentiment analysis; nevertheless, in hate-speech even negative sentiment could still provide useful insight. Our intuition is that the task of hate-speech detection can be further benefited by the incorporation of other sources of information to be used as features into a supervised learning model. A simple statistical analysis on an existing annotated dataset of tweets by BIBREF5 , can easily reveal the existence of significant correlation between the user tendency in expressing opinions that belong to some offensive class (Racism or Sexism), and the annotation labels associated with that class. More precisely, the correlation coefficient value that describes such user tendency was found to be 0.71 for racism in the above dataset, while that value reached as high as 0.76 for sexism. In our opinion, utilizing such user-oriented behavioural data for reinforcing an existing solution is feasible, because such information is retrieva2ble in real-world use-case scenarios like Twitter. This highlights the need to explore the user features more systematically to further improve the classification accuracy of a supervised learning system.\nOur approach employs a neural network solution composed of multiple Long-Short-Term-Memory (LSTM) based classifiers, and utilizes user behavioral characteristics such as the tendency towards racism or sexism to boost performance. Although our technique is not necessarily revolutionary in terms of the deep learning models used, we show in this paper that it is quite effective.\nOur main contributions are: INLINEFORM0 ) a deep learning architecture for text classification in terms of hateful content, which incorporates features derived form the users' behavioural data, INLINEFORM1 ) a language agnostic solution, due to no-use of pre-trained word embeddings, for detecting hate-speech, INLINEFORM2 ) an experimental evaluation of the model on a Twitter dataset, demonstrating the top performance achieved on the classification task. Special focus is given to investigating how the additional features concerning the users' tendency to utter hate-speech, as expressed by their previous history, could leverage the performance. To the best of our knowledge, there has not been done any previous study on exploring features related to the users tendency in hatred content that used a deep learning model.\nThe rest of the paper is organized as follows. In Section SECREF2 we describe the problem of hate speech in more detail, and we refer to the existing work in the field in Section SECREF3 . In Section SECREF4 we present our proposed model, while in Section SECREF5 we refer to the dataset used, the evaluation tests we performed and we discuss the results received. Finally, in Section SECREF6 we summarize our contributions and discuss the future work.\nTo the best of our knowledge, there has not been done any previous study on exploring features related to the users tendency in hatred content that used a deep learning model.",

        "question": "Based on the following paragraph on drinking water, is there a risk of drinking too much water during exercising?",
        "evidence": "The human body contains from 55% to 78% water, depending on body size.[user-generated source?] To function properly, the body requires between one and seven liters (0.22 and 1.54 imp gal; 0.26 and 1.85 U.S. gal)[citation needed] of water per day to avoid dehydration; the precise amount depends on the level of activity, temperature, humidity, and other factors. Most of this is ingested through foods or beverages other than drinking straight water. It is not clear how much water intake is needed by healthy people, though the British Dietetic Association advises that 2.5 liters of total water daily is the minimum to maintain proper hydration, including 1.8 liters (6 to 7 glasses) obtained directly from beverages. Medical literature favors a lower consumption, typically 1 liter of water for an average male, excluding extra requirements due to fluid loss from exercise or warm weather.\nHealthy kidneys can excrete 0.8 to 1 liter of water per hour, but stress such as exercise can reduce this amount. People can drink far more water than necessary while exercising, putting them at risk of water intoxication (hyperhydration), which can be fatal. The popular claim that \"a person should consume eight glasses of water per day\" seems to have no real basis in science. Studies have shown that extra water intake, especially up to 500 milliliters (18 imp fl oz; 17 U.S. fl oz) at mealtime, was associated with weight loss. Adequate fluid intake is helpful in preventing constipation.",

        "evidence": "Pre-trained models BIBREF0, BIBREF1 have received much of attention recently thanks to their impressive results in many down stream NLP tasks. Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference and universal dependency parsing.",

        "evidence": "Deep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available. However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nIn the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset.",

If we conclude that a contract does not exist because the collectability criterion is not met, we don’t record a receivable for consideration that we have not yet received for the services we have already transferred to the customer.

        "question": "Does the proposed G-SAT model considerably reduce the latency time with respect to state-of-the-art DST systems?",
        "answer": "Yes, it does.",
        "evidence": "Spoken dialogue systems, or conversational systems, are designed to interact and assist users using speech and natural language to achieve a certain goal BIBREF0. A consolidated approach to build a task-oriented dialogue system involves a pipeline architecture (see Figure FIGREF1), where each component is trained to perform a sub-task, and the combination of the modules in a given sequence aims at handling the complete task-oriented dialogue. In such a pipeline, a spoken language understanding (SLU) module determines the user's intent and the relevant information that the user is providing represented in terms of slot-value pairs. Then, the dialogue state tracker (DST) uses the information of the SLU together with the past dialogue context and updates its belief state BIBREF1, BIBREF2. In this framework a dialogue state indicates what the user requires at any point in the dialogue, and it is represented as a probability distribution over the possible states (typically a set of pre-defined slot-value pairs specific of the task). The dialogue policy manager, then, decides on the next system action based on the dialogue state. Finally, a natural language generation (NLG) component is responsible for the generation of an utterance that is returned as response to the user.\nIn this paper we focus on the dialogue state tracker component, whose role is to track the state of the dialogue based on the current user utterance, the conversation history and any additional information available to the system BIBREF0. Deep neural network techniques, such as recurrent neural network and convolutional neural networks, are the current state-of-the-art models for DST BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, showing high capacity to generalize from annotated dialogues. As an example, the GLAD model (Global-Locally Self-Attentive Dialogue State Tracker - BIBREF8), employs independent slot-specific encoders, consisting of a recurrent and a self-attention layer, for each of the user utterance, the system action and the slot-value pairs. Another DST system, GCE (Globally Conditioned Encoder - BIBREF9), simplifies the GLAD neural architecture removing the slot-specific recurrent and self-attention layers of the encoder, but still requires separate encoders for the utterance, the system action and the slot-values.\nAlthough the neural network models mentioned above achieve state-of-the-art performance, the complexity of their architectures make them highly inefficient in terms of time complexity, with a significant latency in their prediction time. Such latency may soon become a serious limitation for their deployment into concrete application scenarios with increasing number of slots, where real time is a strong requirement. Along this perspective, this work investigates the time complexity of state-of-the-art DST models and addresses their current limitations. Our contributions are the following:\nwe have designed and implemented an efficient DST, consisting of a Global encoder and Slot-Attentive decoders (G-SAT);\nwe provide empirical evidences (three languages of the WOZ2.0 dataset BIBREF6) that the proposed G-SAT model considerably reduces the latency time with respect to state-of-art DST systems (i.e. over 15 times faster), while keeping the dialogue state prediction inline with such systems;\nfurther experiments show that the proposed model is highly robust when either pre-trained embeddings are used or when they are not used, in this case outperforming state-of-art systems.\nThe implementation of the proposed G-SAT model is publicly available.\nThe paper is structured as follows. Section 2 summarizes the main concepts behind the definition of dialogue state tracking. Section 3 reports the relevant related work. Section 4 provides the details of the proposed G-SAT neural model, and, finally, Section 5 and 6 focus on the experiments and the discussion of the results we achieved.\nOur contributions are the following: we have designed and implemented an efficient DST, consisting of a Global encoder and Slot-Attentive decoders (G-SAT); we provide empirical evidences (three languages of the WOZ2.0 dataset) that the proposed G-SAT model considerably reduces the latency time with respect to state-of-art DST systems (i.e. over 15 times faster), while keeping the dialogue state prediction inline with such systems; further experiments show that the proposed model is highly robust when either pre-trained embeddings are used or when they are not used, in this case outperforming state-of-art systems.",

        "evidence": "Our CNN-based text classification's setup follows Kim2014. Figure FIGREF17 depicts the model's details. From the left side's input texts to the right side's prediction labels, different shapes of tensors flow through the entire network for solving the classification task in an end-to-end mode.\nFirstly, tokenized text strings were converted to a INLINEFORM0 tensor with shape INLINEFORM1 , where INLINEFORM2 represents sentences' maximum length while INLINEFORM3 represents the word-embedding dimension. In this study, we utilized the Word2Vec BIBREF4 embedding vectors ( INLINEFORM4 ) that were trained on 100 billion words of Google News. Next, the embedding matrix was fed into a INLINEFORM5 convolution network with multiple filters. To cover varied reception fields, we used filters of sizes of INLINEFORM6 , INLINEFORM7 , and INLINEFORM8 . For each filter size, INLINEFORM9 filters were utilized. Then, max pooling, which stands for finding the largest value from a vector, was applied to each feature map (total INLINEFORM10 feature maps) output by the INLINEFORM11 convolution. Finally, maximum values from all of INLINEFORM12 filters were formed as a flattened vector to go through a fully connected (FC) layer to predict two possible labels (Laughter vs. No-Laughter). Note that for INLINEFORM13 convolution and FC layer's input, we applied `dropout' BIBREF10 regularization, which entails randomly setting a proportion of network weights to be zero during model training, to overcome over-fitting. By using cross-entropy as the learning metric, the whole sequential network (all weights and bias) could be optimized by using any SGD optimization, e.g., Adam BIBREF13 , Adadelta BIBREF14 , and so on.\n\nWe used two corpora: the TED Talk corpus (denoted as TED) and the Pun of the Day corpus (denoted as Pun). Note that we normalized words in the Pun data to lowercase to avoid a possibly elevated result caused by a special pattern: in the original format, all negative instances started with capital letters. The Pun data allows us to verify that our implementation is consistent with the work reported in yang-EtAl:2015:EMNLP2.\nIn our experiment, we firstly divided each corpus into two parts. The smaller part (the Dev set) was used for setting various hyper-parameters used in text classifiers. The larger portion (the CV set) was then formulated as a 10-fold cross-validation setup for obtaining a stable and comprehensive model evaluation result. For the PUN data, the Dev contains 482 sentences, while the CV set contains 4344 sentences. For the TED data, the Dev set contains 1046 utterances, while the CV set contains 8406 utterances. Note that, with a goal of building a speaker-independent humor detector, when partitioning our TED data set, we always kept all utterances of a single talk within the same partition. To our knowledge, this is the first time that such a strict experimental setup has been used in recognizing humor in conversations, and it makes the humor recognition task on the TED data quite challenging.\nWhen building conventional models, we developed our own feature extraction scripts and used the SKLL python package for building Random Forest models. When implementing CNN, we used the Keras Python package. Regarding hyper-parameter tweaking, we utilized the Tree Parzen Estimation (TPE) method as detailed in TPE. After running 200 iterations of tweaking, we ended up with the following selection: INLINEFORM0 is 6 (entailing that the various filter sizes are INLINEFORM1 ), INLINEFORM2 is 100, INLINEFORM3 is INLINEFORM4 and INLINEFORM5 is INLINEFORM6 , optimization uses Adam BIBREF13 . When training the CNN model, we randomly selected INLINEFORM7 of the training data as the validation set for using early stopping to avoid over-fitting.\nOn the Pun data, the CNN model shows consistent improved performance over the conventional model, as suggested in BIBREF3 . In particular, precision has been greatly increased from INLINEFORM0 to INLINEFORM1 . On the TED data, we also observed that the CNN model helps to increase precision (from INLINEFORM2 to INLINEFORM3 ) and accuracy (from INLINEFORM4 to INLINEFORM5 ). The empirical evaluation results suggest that the CNN-based model has an advantage on the humor recognition task. In addition, focusing on the system development time, generating and implementing those features in the conventional model would take days or even weeks. However, the CNN model automatically learns its optimal feature representation and can adjust the features automatically across data sets. This makes the CNN model quite versatile for supporting different tasks and data domains. Compared with the humor recognition results on the Pun data, the results on the TED data are still quite low, and more research is needed to fully handle humor in authentic presentations.\nOur CNN-based text classification’s setup follows Kim (2014). Figure 2 depicts the model’s details. From the left side’s input texts to the right side’s prediction labels, different shapes of tensors flow through the entire network for solving the classification task in an end-to-end mode.****To our knowledge, this is the first time that such a strict experimental setup has been used in recognizing humor in conversations, and it makes the humor recognition task on the TED data quite challenging.",

Top N terms were selected and added to our dictionary where N=100k for higher count emotions joy, sadness, anger, love and N=50k for thankfulness and fear and N=25k for surprise. Seven binary classifiers were trained for the seven emotions with a batch size of 250 and for 20 epochs with binary cross-entropy as the objective function and Adam optimizer. The architecture of the model can be seen in Figure FIGREF6 . For training each classifier, a balanced dataset was created with selecting all tweets from the target set as class 1 and a random sample of the same size from other classes as class 0.

In the evaluation, we will also evaluate a system variant, where we will set $\\alpha = 0$ , which means that the neural network will not attempt to predict explicit discourse relations and implicit discourse relation prediction will not be influenced by predicting neighboring explicit discourse relations.\nOn the contrary, predicting an implicit discourse relation should rely on understanding the overall contents of its two discourse units (Lin et al., 2014; Rutherford and Xue, 2016).",

First proposed on January 14, 2021, the package builds upon many of the measures in the CARES Act from March 2020 and in the Consolidated Appropriations Act, 2021, from December.\n\nBeginning on February 2, 2021, Democrats in the United States Senate started to open debates on a budget resolution that would allow them to pass the stimulus package through the process of reconciliation which would not require support from Republicans. The House of Representatives voted 218–212 to approve its version of the budget resolution. A so-called vote-a-rama session started two days later after the resolution was approved, and the Senate introduced amendments in the relief package. The day after, Vice President Kamala Harris cast her first tie-breaking vote as vice president in order to give the Senate's approval to start the reconciliation process, with the House following suit by voting 219–209 to agree to the Senate version of the resolution.\n\nOn February 8, 2021, the Financial Services and Education and Labor committees released a draft of $1.9 trillion stimulus legislation. A portion of the relief package was approved by the House Ways and Means on February 11, setting it up for a vote in the House. The legislation was also approved by the Transportation and Infrastructure, Small Business, and House Veterans Affairs committees. On February 22, the House Budget Committee voted 19–16 to advance the bill to the House for a floor vote. The bill passed the House by a vote of 219–212 on February 27. All but two Democrats voted for the bill and all Republicans voted against the bill. A modified version passed the Senate on March 6 by a vote of 50–49. The final amended bill was passed by the House on March 10 by a vote of 220–211 with one Democrat voting against it with all Republicans.

        "answer": "Texas is know as the BBQ capital of the world, and Texas brisket leads the pack. For true Texas brisket all you need is salt, pepper, smoke and time!\n\n1. Purchase a whole packer brisket with both the point and flat muscle included. Prime grade brisket is ideal as it will have more fat marbling, which means more flavor and juiciness. However, choice grade will work fine for most cooks. Plan on 1/2 lb per person.\n\n2. Trim your brisket to remove and hard pieces of fat that will not render in the cooking process. I recommend leaving about 1/4 inch of fat on the point side, and trim off all fat off the flat. Note: the brisket trimming make great fat to mix into burgers!\n\n3. Texas brisket is seasoned only with coarse salt and coarse black pepper. I prefer a 50/50 mix. There are MANY brisket rubs available if you are looking to spice up your brisket from the traditional Texas salt and pepper rub.\n\n4. Use a good quality hardwood lump charcoal in your smoker. I use oak as a base wood with a little bit of hickory mixed in. You can use any smoker that can maintain a consistent temperature of 225-250 degrees. I prefer the Big Green Egg, but there are great smokers available from Weber, Traeger, CampChef and many more.\n\n5. Smoke the brisket at 225 degrees until the internal temperature reaches 165-170 degrees. I then remove the brisket, wrap in butcher paper, and return to the smoker until the internal temperature reaches 202 degrees.\n\n6. When the brisket reaches 202 degrees, remove from the smoker and REST. DO NOT SKIP THE REST. Resting the brisket allows those hot and bubbly juices to settle into the meat. I prefer resting my brisket in a cooler covered in towels for 2 hours, but can rest as long as 4 hours before serving.\n\n7. When you are ready to serve, I separate the two pieces, flat and point.Slice the flat against the grain for maximum tenderness. Cube the point for burnt ends.\n\n8. Serve and enjoy!",

In nineteenth and early twentieth century Europe, artwork was a common form of racialization which targeted countries in the Middle East and Asia. The artwork, predominantly paintings, were portrayed in order to instill prejudice in the Western populations through sexualizing and manipulating images. One of the most prominent examples of Orientalist work in art is a piece by Eugène Delacroix titled Women of Algiers in their Apartment. Dating back to 1834, it portrays three women resting in a harem in exotic clothing while an African woman is dressed in plain clothing, depicting her role as a servant. Fine textiles, hookahs, and other paraphernalia adorn the room, which represents a European fantasy of an exotic scene. Attempts to portray these cultures as strange, foreign and exotic through Orientalism led to intolerance towards the Arab and Asian communities in Europe and the United States. Others argue that Delacroix, who travelled in North Africa sketching extensively, was depicting a realistic scene of the era based on his first-hand knowledge and experience. In such an interpretation the clothing, for example, is consistent with the times, as Arab North Africans dressed differently from Europeans, and kept black slaves who would not have been treated as equals.",

        "question": "What components do they divide a terminological ontology into?",
        "answer": "Topic hierarchies and topic relations.",
        "evidence": "Although researchers have made significant progress on knowledge acquisition and have proposed many ontologies, for instance, WordNet BIBREF0 , DBpedia BIBREF1 , YAGO BIBREF2 , Freebase, BIBREF3 Nell BIBREF4 , DeepDive BIBREF5 , Domain Cartridge BIBREF6 , Knowledge Vault BIBREF7 , INS-ES BIBREF8 , iDLER BIBREF9 , and TransE-NMM BIBREF10 , current ontology construction methods still rely heavily on manual parsing and existing knowledge bases. This raises challenges for learning ontologies in new domains. While a strong ontology parser is effective in small-scale corpora, an unsupervised model is beneficial for learning new entities and their relations from new data sources, and is likely to perform better on larger corpora.\nIn this paper, we focus on unsupervised terminological ontology learning and formalize a terminological ontology as a hierarchical structure of subject-verb-object triplets. We divide a terminological ontology into two components: topic hierarchies and topic relations. Topics are presented in a tree structure where each node is a topic label (noun phrase), the root node represents the most general topic, the leaf nodes represent the most specific topics, and every topic is composed of its topic label and its descendant topic labels. Topic hierarchies are preserved in topic paths, and a topic path connects a list of topics labels from the root to a leaf. Topic relations are semantic relationships between any two topics or properties used to describe one topic. Figure FIGREF1 depicts an example of a terminological ontology learned from a corpus about European cities. We extract terminological ontologies by applying unsupervised hierarchical topic modeling and relation extraction to plain text.\nTopic modeling was originally used for topic extraction and document clustering. The classical topic model, latent Dirichlet allocation (LDA) BIBREF11 , simplifies a document as a bag of its words and describes a topic as a distribution of words. Prior research BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 has shown that LDA-based approaches are adequate for (terminological) ontology learning. However, these models are deficient in that they still need human supervision to decide the number of topics, and to pick meaningful topic labels usually from a list of unigrams. Among models not using unigrams, LDA-based Global Similarity Hierarchy Learning (LDA+GSHL) BIBREF13 only extracts a subset of relations: “broader\" and “related\" relations. In addition, the topic hierarchies of KB-LDA BIBREF17 rely on hypernym-hyponym pairs capturing only a subset of hierarchies.\nConsidering the shortcomings of the existing methods, the main objectives of applying topic modeling to ontology learning are threefold.\nTo achieve the first objective, we extract noun phrases and then propose a sampling method to estimate the number of topics. For the second objective, we use language parsing and relation extraction to learn relations for the noun phrases. Regarding the third objective, we adapt and improve the hierarchical latent Dirichlet allocation (hLDA) model BIBREF19 , BIBREF20 . hLDA is not ideal for ontology learning because it builds topics from unigrams (which are not descriptive enough to serve as entities in ontologies) and the topics may contain words from multiple domains when input data have documents from many domains (see Section SECREF2 and Figure FIGREF55 ). Our model, hrLDA, overcomes these deficiencies. In particular, hrLDA represents topics with noun phrases, uses syntax and document structures such as paragraph indentations and item lists, assigns multiple topic paths for every document, and allows topic trees to grow vertically and horizontally.\nThe primary contributions of this work can be specified as follows.\nThe rest of this paper is organized into five parts. In Section 2, we provide a brief background of hLDA. In Section 3, we present our hrLDA model and the ontology generation method. In Section 4, we demonstrate empirical results regarding topic hierarchies and generated terminological ontologies. Finally, in Section 5, we present some concluding remarks and discuss avenues for future work and improvements.\nWe divide a terminological ontology into two components: topic hierarchies and topic relations.",

        "evidence": "The scientific process by which the deep learning research community operates is guided by empirical studies that evaluate the relative quality of models. Complicating matters, the measured performance of a model depends not only on its architecture (and data), but it can strongly depend on hyperparameter values that affect learning, regularisation, and capacity. This hyperparameter dependence is an often inadequately controlled source of variation in experiments, which creates a risk that empirically unsound claims will be reported.\nIn this paper, we use a black-box hyperparameter optimisation technique to control for hyperparameter effects while comparing the relative performance of language modelling architectures based on LSTMs, Recurrent Highway Networks BIBREF0 and NAS BIBREF1 . We specify flexible, parameterised model families with the ability to adjust embedding and recurrent cell sizes for a given parameter budget and with fine grain control over regularisation and learning hyperparameters.\nOnce hyperparameters have been properly controlled for, we find that LSTMs outperform the more recent models, contra the published claims. Our result is therefore a demonstration that replication failures can happen due to poorly controlled hyperparameter variation, and this paper joins other recent papers in warning of the under-acknowledged existence of replication failure in deep learning BIBREF2 , BIBREF3 . However, we do show that careful controls are possible, albeit at considerable computational cost.\nSeveral remarks can be made in light of these results. First, as (conditional) language models serve as the central building block of many tasks, including machine translation, there is little reason to expect that the problem of unreliable evaluation is unique to the tasks discussed here. However, in machine translation, carefully controlling for hyperparameter effects would be substantially more expensive because standard datasets are much larger. Second, the research community should strive for more consensus about appropriate experimental methodology that balances costs of careful experimentation with the risks associated with false claims. Finally, more attention should be paid to hyperparameter sensitivity. Models that introduce many new hyperparameters or which perform well only in narrow ranges of hyperparameter settings should be identified as such as part of standard publication practice.\nWe specify flexible, parameterised model families with the ability to adjust embedding and recurrent cell sizes for a given parameter budget and with fine grain control over regularisation and learning hyperparameters.",

Multilingual g2p, in which the various languages have similar but different and possibly contradictory spelling rules, can be seen as an extreme case of that. Therefore, a data- driven sequence-to-sequence model is a natural choice.",
        "evidence": "g2p is the problem of converting the orthographic representation of a word into a phonemic representation. A phoneme is an abstract unit of sound which may have different realizations in different contexts. For example, the English phoneme has two phonetic realizations (or allophones):\nEnglish speakers without linguistic training often struggle to perceive any difference between these sounds. Writing systems usually do not distinguish between allophones: and are both written as INLINEFORM0 p INLINEFORM1 in English. The sounds are written differently in languages where they contrast, such as Hindi and Eastern Armenian.\nMost writing systems in use today are glottographic, meaning that their symbols encode solely phonological information. But despite being glottographic, in few writing systems do graphemes correspond one-to-one with phonemes. There are cases in which multiple graphemes represent a single phoneme, as in the word the in English:\n\nThere are cases in which a single grapheme represents multiple phonemes, such as syllabaries, in which each symbol represents a syllable.\nIn many languages, there are silent letters, as in the word hora in Spanish:\n\nThere are more complicated correspondences, such as the silent e in English that affects the pronunciation of the previous vowel, as seen in the pair of words cape and cap.\nIt is possible for an orthographic system to have any or all of the above phenomena while remaining unambiguous. However, some orthographic systems contain ambiguities. English is well-known for its spelling ambiguities. Abjads, used for Arabic and Hebrew, do not give full representation to vowels.\nConsequently, g2p is harder than simply replacing each grapheme symbol with a corresponding phoneme symbol. It is the problem of replacing a grapheme sequence INLINEFORM0 \nwith a phoneme sequence INLINEFORM0 \nwhere the sequences are not necessarily of the same length. Data-driven g2p is therefore the problem of finding the phoneme sequence that maximizes the likelihood of the grapheme sequence: INLINEFORM0 \nData-driven approaches are especially useful for problems in which the rules that govern them are complex and difficult to engineer by hand. g2p for languages with ambiguous orthographies is such a problem.

However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 .

However, after the August 2011 stock markets fall, on October 4, 2011, the index briefly broke below 1,100.\n\nThe index rose 13% in 2012 despite significant volatility amid electoral and fiscal uncertainty and round 3 of quantitative easing. On December 31, 2012, the index closed at 1,426.19, an annual gain of 13% and its biggest gain in 3 years.\n\nOn March 28, 2013, the index surpassed its closing high of 1,565.15, recovering all its losses from the Great Recession.

It was the first monthly decline in 11 months. In the third quarter of 2018, the index posted its best quarter since 2013. However, the index fell 11% in the month of December 2018, its worst December performance since the Great Depression. The index fell 6% in 2018, its worst year in a decade.\n\nHowever, in 2019, the index posted its best first half in 22 years including the best June since 1938.

The index rose 31.5% in 2019, one of its best years.\n\nOn February 19, 2020, the index hit a new closing peak of 3,386.15; however, it fell 10% in the next six trading days, its fastest drop from a new peak as a result of the onset of the COVID-19 pandemic and COVID-19 recession. On March 23, 2020, at the trough of the 2020 stock market crash, the index had fallen 34% from its peak. Overall, the index fell 20% during the first quarter of 2020, its worst quarter since 2008.

        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nMoreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer.",

        "evidence": "We now evaluate LiLi in terms of its predictive performance and strategy formulation abilities.\nData: We use two standard datasets (see Table 4): (1) Freebase FB15k, and (2) WordNet INLINEFORM0 . Using each dataset, we build a fairly large graph and use it as the original KB ( INLINEFORM1 ) for evaluation. We also augment INLINEFORM2 with inverse triples ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ) for each ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) following existing KBC methods.\nParameter Settings. Unless specified, the empirically set parameters (see Table 1) of LiLi are: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 , INLINEFORM4 , INLINEFORM5 , INLINEFORM6 , INLINEFORM7 , INLINEFORM8 , INLINEFORM9 , INLINEFORM10 . For training RL-model with INLINEFORM11 -greedy strategy, we use INLINEFORM12 , INLINEFORM13 , pre-training steps=50000. We used Keras deep learning library to implement and train the prediction model. We set batch-size as 128, max. training epoch as 150, dropout as 0.2, hidden units and embedding size as 300 and learning rate as 5e-3 which is reduced gradually on plateau with factor 0.5 and patience 5. Adam optimizer and early stopping were used in training. We also shuffle INLINEFORM14 in each epoch and adjust class weights inversely proportional to class frequencies in INLINEFORM15 .\nLabeled Dataset Generation and Simulated User Creation. We create a simulated user for each KB to evaluate LiLi. We create the labeled datasets, the simulated user’s knowledge base ( INLINEFORM0 ), and the base KB ( INLINEFORM1 ) from INLINEFORM2 . INLINEFORM3 used as the initial KB graph ( INLINEFORM4 ) of LiLi.\nWe followed BIBREF16 for labeled dataset generation. For Freebase, we found 86 relations with INLINEFORM0 triples and randomly selected 50 from various domains. We randomly shuffle the list of 50 relations, select 25% of them as unknown relations and consider the rest (75%) as known relations. For each known relation INLINEFORM1 , we randomly shuffle the list of distinct triples for INLINEFORM2 , choose 1000 triples and split them into 60% training, 10% validation and 20% test. Rest 10% along with the leftover (not included in the list of 1000) triples are added to INLINEFORM3 . For each unknown relation INLINEFORM4 , we remove all triples of INLINEFORM5 from INLINEFORM6 and add them to INLINEFORM7 . In this process, we also randomly choose 20% triples as test instances for unknown INLINEFORM8 which are excluded from INLINEFORM9 . Note that, now INLINEFORM10 has at least 10% of chosen triples for each INLINEFORM11 (known and unknown) and so, user is always able to provide clues for both cases. For each labeled dataset, we randomly choose 10% of the entities present in dataset triples, remove triples involving those entities from INLINEFORM12 and add to INLINEFORM13 . At this point, INLINEFORM14 gets reduced to INLINEFORM15 and is used as INLINEFORM16 for LiLi. The dataset stats in Table 4 shows that the base KB (60% triples of INLINEFORM17 ) is highly sparse (compared to original KB) which makes the inference task much harder. WordNet dataset being small, we select all 18 relations for evaluation and create labeled dataset, INLINEFORM18 and INLINEFORM19 following Freebase. Although the user may provide clues 100% of the time, it often cannot respond to MLQs and CLQs (due to lack of required triples/facts). Thus, we further enrich INLINEFORM20 with external KB triples.\nGiven a relation INLINEFORM0 and an observed triple ( INLINEFORM1 , INLINEFORM2 , INLINEFORM3 ) in training or testing, the pair ( INLINEFORM4 , INLINEFORM5 ) is regarded as a +ve instance for INLINEFORM6 . Following BIBREF18 , for each +ve instance ( INLINEFORM7 , INLINEFORM8 ), we generate two negative ones, one by randomly corrupting the source INLINEFORM9 , and the other by corrupting the target INLINEFORM10 . Note that, the test triples are not in INLINEFORM11 or INLINEFORM12 and none of the -ve instances overlap with the +ve ones.\nBaselines. As none of the existing KBC methods can solve the OKBC problem, we choose various versions of LiLi as baselines.\nSingle: Version of LiLi where we train a single prediction model INLINEFORM0 for all test relations.\nSep: We do not transfer (past learned) weights for initializing INLINEFORM0 , i.e., we disable LL.\nF-th): Here, we use a fixed prediction threshold 0.5 instead of relation-specific threshold INLINEFORM0 .\nBG: The missing or connecting links (when the user does not respond) are filled with “@-RelatedTo-@\" blindly, no guessing mechanism.\nw/o PTS: LiLi does not ask for additional clues via past task selection for skillset improvement.\nEvaluation Metrics. To evaluate the strategy formulation ability, we introduce a measure called Coverage( INLINEFORM0 ), defined as the fraction of total query data instances, for which LiLi has successfully formulated strategies that lead to winning. If LiLi wins on all episodes for a given dataset, INLINEFORM1 is 1.0. To evaluate the predictive performance, we use Avg. MCC and avg. +ve F1 score.\nBaselines.

        "answer": "As noted in Section 5.2 (first paragraph), the continuous control experiments already don't apply this logarithmic transformation; we found that it hurt exploration on these domains. This result raises an interesting direction for future work: how can we design model-based RL algorithms for complex domains that explore efficiently while still maximizing a provable lower bound on expected return?",
        "evidence": "Our first comparison uses three locomotion tasks from the OpenAI Gym benchmark, which has become the standard benchmark for model-based RL algorithms. Thes tasks have dense rewards and pose no significant exploration challenge, so we do not expect MnM to outperform prior methods. The results (Fig. (top left)) show that MnM performs roughly on par with MBPO.\nTasks with sparse rewards, complex contact dynamics, and those requiring hard exploration often present a challenge for model-based RL algorithms, which are liable to exploit inaccuracies in the learned dynamics model. Our next experiment evaluates MnM on control tasks used in prior work that demonstrate these properties. These tasks the sparse-reward cartpole task from the DM Control benchmark, four manipulation tasks from the Metaworld benchmark, and four dexterous manipulation tasks from the ROBEL benchmark. See Appendix C for experiment details. The results shown in Fig. indicate that the complex environment dynamics of these tasks can cause prior model-based algorithms (MBPO) to perform worse than model-free algorithms (SAC), both in terms of asymptotic performance and sample complexity. Nonetheless, we observe that MnM frequently outperforms all prior methods and, more importantly, it consistently does well across all tasks. We include ablation experiments in Appendix B.1.\nReal Dynamics:  Finally, we visualize the dynamics learned by MnM on two robotic control tasks. These tasks have deterministic dynamics, so our theory would predict that an idealized version of MnM would learn a dynamics model exactly equal to the deterministic dynamics. However, our implementation relies on function approximation (neural networks) to learn the dynamics, and the limited capacity of function approximators makes otherwisedeterministic dynamics appear stochastic. On the Pusher-v2 task, the MnM dynamics cause the puck to move towards the robot arm even before the arm has come in contact with the puck. While this movement is not physically realistic, it may make the exploration problem easier. On the HalfChetah-v2 task, the MnM dynamics increase the probability that the agent remains upright after tripping, likely making it easier for the agent to learn how to run. We expect that the implicit stochasticity caused by function approximation to be especially important for real-world tasks, where the complexity of the real dynamics often dwarfs the capacity of the learned dynamics model.\nOur next experiments use continuous-control robotic tasks to answer two questions. We first investigate whether MnM performs at least comparably with prior work. We then study tasks with sparse rewards and more challenging exploration, where we suspect the optimistic dynamics learned by MnM may be beneficial. We illustrate a subset of the environments in Fig. 4 and include implementation details in Appendix C.2. One detail of note is that we omit the reward augmentation (Eq. 3) for MnM during these experiments, as it hinders exploration leading to lower returns. We use MBPO (Janner et al., 2019) as a baseline for modelbased RL because it achieves state-of-the-art results and is a prototypical example of model-based RL algorithms that use maximum likelihood models.",

Assuming a capitalist economy, job training is important because of market dynamics, supply and demand.  In this case, demand are the available jobs and supply are the skilled workers who provide work in those jobs.  As technology advances, new innovations are made and cyclical market segments ebb and flow, the demand for highly skilled workers changes.  Upskilling is important as it helps workers to maintain valuable skills in their given field and the goal is to keep up with the technology advances in their respective field.  Reskilling is most often more closely linked to cyclical market forces where the demand for jobs in one field go down and another go up; reskilling is acquiring skills in the field with growing demand for jobs when a worker possesses skills in a field with declining demand for jobs or their skills.",

        "evidence": "In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes when time advances.\n\nThe derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the \"instantaneous rate of change\", the ratio of the instantaneous change in the dependent variable to that of the independent variable.\n\nDerivatives can be generalized to functions of several real variables. In this generalization, the derivative is reinterpreted as a linear transformation whose graph is (after an appropriate translation) the best linear approximation to the graph of the original function. The Jacobian matrix is the matrix that represents this linear transformation with respect to the basis given by the choice of independent and dependent variables. It can be calculated in terms of the partial derivatives with respect to the independent variables. For a real-valued function of several variables, the Jacobian matrix reduces to the gradient vector.\n\nThe process of finding a derivative is called differentiation. The reverse process is called antidifferentiation. The fundamental theorem of calculus relates antidifferentiation with integration. Differentiation and integration constitute the two fundamental operations in single-variable calculus.",

        "evidence": "In this section, we describe methods to explore combinatorially sized action spaces such as text-games—focusing especially on methods that can deal with their inherent bottleneck structure. We first describe our method that explicitly attempts to detect bottlenecks and then describe how an exploration algorithm such as Go Explore BIBREF9 can leverage knowledge graphs.\nKG-A2C-chained An example of a bottleneck can be seen in Figure FIGREF1. We extend the KG-A2C algorithm as follows. First, we detect bottlenecks as states where the agent is unable to progress any further. We set a patience parameter and if the agent has not seen a higher score in patience steps, the agent assumes it has been limited by a bottleneck. Second, when a bottleneck is found, we freeze the policy that gets the agent to the state with the highest score. The agent then begins training a new policy from that particular state.\nSimply freezing the policy that led to the bottleneck, however, can potentially result in a policy one that is globally sub-optimal. We therefore employ a backtracking strategy that restarts exploration from each of the $n$ previous steps—searching for a more optimal policy that reaches that bottleneck. At each step, we keep track of a buffer of $n$ states and admissible actions that led up to that locally optimal state. We force the agent to explore from this state to attempt to drive it out of the local optima. If it is further unable to find itself out of this local optima, we refresh the training process again, but starting at the state immediately before the agent reaches the local optima. If this continues to fail, we continue to iterate through this buffer of seen states states up to that local optima until we either find a more optimal state or we run out of states to refresh from, in which we terminate the training algorithm.\nKG-A2C-Explore Go-Explore BIBREF9 is an algorithm that is designed to keep track of sub-optimal and under-explored states in order to allow the agent to explore upon more optimal states that may be a result of sparse rewards. The Go-Explore algorithm consists of two phases, the first to continuously explore until a set of promising states and corresponding trajectories are found on the basis of total score, and the second to robustify this found policy against potential stochasticity in the game. Promising states are defined as those states when explored from will likely result in higher reward trajectories. Since the text games we are dealing with are mostly deterministic, with the exception of Zork in later stages, we only focus on using Phase 1 of the Go-Explore algorithm to find an optimal policy. BIBREF10 look at applying Go-Explore to text-games on a set of simpler games generated using the game generation framework TextWorld BIBREF1. Instead of training a policy network in parallel to generate actions used for exploration, they use a small set of “admissible actions”—actions guaranteed to change the world state at any given step during Phase 1—to explore and find high reward trajectories. This space of actions is relatively small (of the order of $10^2$ per step) and so finding high reward trajectories in larger action-spaces such as in Zork would be infeasible\nGo-Explore maintains an archive of cells—defined as a set of states that map to a single representation—to keep track of promising states. BIBREF9 simply encodes each cell by keeping track of the agent's position and BIBREF10 use the textual observations encoded by recurrent neural network as a cell representation. We improve on this implementation by training the KG-A2C network in parallel, using the snapshot of the knowledge graph in conjunction with the game state to further encode the current state and use this as a cell representation. At each step, Go-Explore chooses a cell to explore at random (weighted by score to prefer more advanced cells). The KG-A2C will run for a number of steps, starting with the knowledge graph state and the last seen state of the game from the cell. This will generate a trajectory for the agent while further training the KG-A2C at each iteration, creating a new representation for the knowledge graph as well as a new game state for the cell. After expanding a cell, Go-Explore will continue to sample cells by weight to continue expanding its known states. At the same time, KG-A2C will benefit from the heuristics of selecting preferred cells and be trained on promising states more often.\nIn this section, we describe methods to explore combinatorially sized action spaces such as text-games—focusing especially on methods that can deal with their inherent bottleneck structure.",

So much so that it is easy to overlook their potential to benefit society by promoting equity, diversity, and fairness. For example, machines do not take bribes to do their jobs, they can determine eligibility for a loan without being influenced by the color of the applicant's skin, and they can provide access to information and services without discrimination based on gender or sexual orientation. Nonetheless, as machine learning systems become more human-like in their predictions, they can also perpetuate human biases. Some learned biases may be beneficial for the downstream application (e.g., learning that humans often use some insect names, such as spider or cockroach, to refer to unpleasant situations). Other biases can be inappropriate and result in negative experiences for some groups of people. Examples include, loan eligibility and crime recidivism prediction systems that negatively assess people belonging to a certain pin/zip code (which may disproportionately impact people of a certain race) BIBREF0 and resumé sorting systems that believe that men are more qualified to be programmers than women BIBREF1 . Similarly, sentiment and emotion analysis systems can also perpetuate and accentuate inappropriate human biases, e.g., systems that consider utterances from one race or gender to be less positive simply because of their race or gender, or customer support systems that prioritize a call from an angry male over a call from the equally angry female.\nPredictions of machine learning systems have also been shown to be of higher quality when dealing with information from some groups of people as opposed to other groups of people. For example, in the area of computer vision, gender classification systems perform particularly poorly for darker skinned females BIBREF2 . Natural language processing (NLP) systems have been shown to be poor in understanding text produced by people belonging to certain races BIBREF3 , BIBREF4 . For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.\nEven though there is some recent work highlighting such inappropriate biases (such as the work mentioned above), each such past work has largely focused on just one or two systems and resources. Further, there is no benchmark dataset for examining inappropriate biases in natural language systems. In this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC). We used the EEC as a supplementary test set in a recent shared task on predicting sentiment and emotion intensity in tweets, SemEval-2018 Task 1: Affect in Tweets BIBREF5 . In particular, we wanted to test a hypothesis that a system should equally rate the intensity of the emotion expressed by two sentences that differ only in the gender/race of a person mentioned. Note that here the term system refers to the combination of a machine learning architecture trained on a labeled dataset, and possibly using additional language resources. The bias can originate from any or several of these parts. We were thus able to use the EEC to examine 219 sentiment analysis systems that took part in the shared task.\nWe compare emotion and sentiment intensity scores that the systems predict on pairs of sentences in the EEC that differ only in one word corresponding to race or gender (e.g., `This man made me feel angry' vs. `This woman made me feel angry'). We find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender. We also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.\nDespite the work we describe here and what others have proposed in the past, it should be noted that there are no simple solutions for dealing with inappropriate human biases that percolate into machine learning systems. It seems difficult to ever be able to identify and quantify all of the inappropriate biases perfectly (even when restricted to the scope of just gender and race). Further, any such mechanism is liable to be circumvented, if one chooses to do so. Nonetheless, as developers of sentiment analysis systems, and NLP systems more broadly, we cannot absolve ourselves of the ethical implications of the systems we build. Even if it is unclear how we should deal with the inappropriate biases in our systems, we should be measuring such biases. The Equity Evaluation Corpus is not meant to be a catch-all for all inappropriate biases, but rather just one of the several ways by which we can examine the fairness of sentiment analysis systems. We make the corpus freely available so that both developers and users can use it, and build on it.\nWe find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender.",

        "question": "Which of the Jurassic Park movies were based on novels?",
        "evidence": "Jurassic Park, later also referred to as Jurassic World, is an American science fiction media franchise created by Michael Crichton and centered on a disastrous attempt to create a theme park of cloned dinosaurs. It began in 1990 when Universal Pictures and Amblin Entertainment bought the rights to Crichton's novel Jurassic Park before it was published. The book was successful, as was Steven Spielberg's 1993 film adaptation. The film received a theatrical 3D re-release in 2013, and was selected in 2018 for preservation in the United States National Film Registry by the Library of Congress as being \"culturally, historically, or aesthetically significant\". A 1995 sequel novel, The Lost World, was followed by a film adaptation in 1997. Subsequent films in the series, including Jurassic Park III (2001), are not based on the novels.\n\nIn 2015, a second trilogy of films began with the fourth film in the series, Jurassic World. The film was successful, becoming the first film to gross over $500 million worldwide in its opening weekend, and grossed over $1.6 billion through the course of its theatrical run, making it the third highest-grossing film at the time. It became the second highest-grossing film of 2015, and is currently the eighth highest-grossing film of all time. When adjusted for monetary inflation, Jurassic World is the second highest-grossing film in the franchise after Jurassic Park. A sequel, Jurassic World: Fallen Kingdom (2018) grossed over $1.3 billion worldwide, making it the third Jurassic film to pass the billion-dollar mark. It is the third highest-grossing film of 2018, and currently the 18th highest-grossing film of all time. The final film in the trilogy, Jurassic World Dominion, was released in 2022.

JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km). JDAM-equipped bombs range from 500 to 2,000 pounds (230 to 910 kg). The JDAM's guidance system was jointly developed by the United States Air Force and United States Navy, hence the \"joint\" in JDAM. When installed on a bomb, the JDAM kit is given a GBU (Guided Bomb Unit) identifier, superseding the Mark 80 or BLU (Bomb, Live Unit) nomenclature of the bomb to which it is attached.\n\nThe JDAM is not a stand-alone weapon; rather it is a \"bolt-on\" guidance package that converts unguided gravity bombs into precision-guided munitions (PGMs). The key components of the system consist of a tail section with aerodynamic control surfaces, a (body) strake kit, and a combined inertial guidance system and GPS guidance control unit.\n\nThe JDAM was meant to improve upon laser-guided bomb and imaging infrared technology, which can be hindered by bad ground and weather conditions. Laser seekers are now being fitted to some JDAMs.",
        "answer": "The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs to precision-guided munitions. There are several reasons why JDAM is one of the most cost effective weapons ever invented.\n\nBy using GPS navigation, the JDAM guidance kit can be extremely cheap, as low as $25k/kit.  It is likely cheaper than any other precision-guided weapons.\n\nGPS navigation provides good targeting precision, typically within meters. Combined with blast radius of 500-2000 lbs unguided bombs, JDAM can effectively destroy any targets on the ground.\n\nBecause JDAM has navigation capability, pilots no longer need to precisely aim the bombers  against the targets. It allows a bomber to quickly and precisely hit multiple targets along the route.\n\nSome JDAM guidance kits include targeting sensors, such as laser targeting. They can be used against mobile targets, which further increases the use cases for JDAM.\n\nIn summary, by combining dumb bombs with a guidance kit, JDAM becomes a very cost effective weapon system, and is widely adopted by the US and other military forces.",

        "question": "What are the two phases of the Go-Explore algorithm?",
        "answer": "The Go-Explore algorithm consists of two phases, the first to continuously explore until a set of promising states and corresponding trajectories are found on the basis of total score, and the second to robustify this found policy against potential stochasticity in the game.",
        "evidence": "In this section, we describe methods to explore combinatorially sized action spaces such as text-games—focusing especially on methods that can deal with their inherent bottleneck structure. We first describe our method that explicitly attempts to detect bottlenecks and then describe how an exploration algorithm such as Go Explore BIBREF9 can leverage knowledge graphs.\nKG-A2C-chained An example of a bottleneck can be seen in Figure FIGREF1. We extend the KG-A2C algorithm as follows. First, we detect bottlenecks as states where the agent is unable to progress any further. We set a patience parameter and if the agent has not seen a higher score in patience steps, the agent assumes it has been limited by a bottleneck. Second, when a bottleneck is found, we freeze the policy that gets the agent to the state with the highest score. The agent then begins training a new policy from that particular state.\nSimply freezing the policy that led to the bottleneck, however, can potentially result in a policy one that is globally sub-optimal. We therefore employ a backtracking strategy that restarts exploration from each of the $n$ previous steps—searching for a more optimal policy that reaches that bottleneck. At each step, we keep track of a buffer of $n$ states and admissible actions that led up to that locally optimal state. We force the agent to explore from this state to attempt to drive it out of the local optima. If it is further unable to find itself out of this local optima, we refresh the training process again, but starting at the state immediately before the agent reaches the local optima. If this continues to fail, we continue to iterate through this buffer of seen states states up to that local optima until we either find a more optimal state or we run out of states to refresh from, in which we terminate the training algorithm.\nKG-A2C-Explore Go-Explore BIBREF9 is an algorithm that is designed to keep track of sub-optimal and under-explored states in order to allow the agent to explore upon more optimal states that may be a result of sparse rewards. The Go-Explore algorithm consists of two phases, the first to continuously explore until a set of promising states and corresponding trajectories are found on the basis of total score, and the second to robustify this found policy against potential stochasticity in the game. Promising states are defined as those states when explored from will likely result in higher reward trajectories. Since the text games we are dealing with are mostly deterministic, with the exception of Zork in later stages, we only focus on using Phase 1 of the Go-Explore algorithm to find an optimal policy. BIBREF10 look at applying Go-Explore to text-games on a set of simpler games generated using the game generation framework TextWorld BIBREF1. Instead of training a policy network in parallel to generate actions used for exploration, they use a small set of “admissible actions”—actions guaranteed to change the world state at any given step during Phase 1—to explore and find high reward trajectories. This space of actions is relatively small (of the order of $10^2$ per step) and so finding high reward trajectories in larger action-spaces such as in Zork would be infeasible\nGo-Explore maintains an archive of cells—defined as a set of states that map to a single representation—to keep track of promising states. BIBREF9 simply encodes each cell by keeping track of the agent's position and BIBREF10 use the textual observations encoded by recurrent neural network as a cell representation. We improve on this implementation by training the KG-A2C network in parallel, using the snapshot of the knowledge graph in conjunction with the game state to further encode the current state and use this as a cell representation. At each step, Go-Explore chooses a cell to explore at random (weighted by score to prefer more advanced cells). The KG-A2C will run for a number of steps, starting with the knowledge graph state and the last seen state of the game from the cell. This will generate a trajectory for the agent while further training the KG-A2C at each iteration, creating a new representation for the knowledge graph as well as a new game state for the cell. After expanding a cell, Go-Explore will continue to sample cells by weight to continue expanding its known states. At the same time, KG-A2C will benefit from the heuristics of selecting preferred cells and be trained on promising states more often.\nThe Go-Explore algorithm consists of two phases, the first to continuously explore until a set of promising states and corresponding trajectories are found on the basis of total score, and the second to robustify this found policy against potential stochasticity in the game.",

        "question": "What does the proposed method reveal?",
        "answer": "Reveals multiple levels of intrinsic structure in the topics of the dataset.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nOur method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence.",

        "evidence": "Simple word-based approaches, if used for blocking the posting of text or blacklisting users, not only fail to identify subtle offensive content, but they also affect the freedom of speech and expression. The word ambiguity problem – that is, a word can have different meanings in different contexts – is mainly responsible for the high false positive rate in such approaches. Ordinary NLP approaches on the other hand, are ineffective to detect unusual spelling, experienced in user-generated comment text. This is best known as the spelling variation problem, and it is caused either by unintentional or intentional replacement of single characters in a token, aiming to obfuscate the detectors.\nIn general, the complexity of the natural language constructs renders the task quite challenging. The employment of supervised learning classification methods for hate speech detection is not new. BIBREF6 reported performance for a simple LSTM classifier not better than an ordinary SVM, when evaluated on a small sample of Facebook data for only 2 classes (Hate, No-Hate), and 3 different levels of strength of hatred. BIBREF7 described another way of detecting offensive language in tweets, based on some supervised model. They differentiate hate speech from offensive language, using a classifier that involves naive Bayes, decision trees and SVM. Also, BIBREF8 attempted to discern abusive content with a supervised model combining various linguistic and syntactic features in the text, considered at character uni-gram and bi-gram level, and tested on Amazon data. In general, we can point out the main weaknesses of NLP-based models in their non-language agnostic nature and the low scores in detection.\nUnsupervised learning approaches are quite common for detecting offensive messages in text by applying concepts from NLP to exploit the lexical syntactic features of sentences BIBREF9 , or using AI-solutions and bag-of-words based text-representations BIBREF10 . The latter is known to be less effective for automatic detection, since hatred users apply various obfuscation tricks, such as replacing a single character in offensive words. For instance, applying a binary classifier onto a paragraph2vec representation of words has already been attempted on Amazon data in the past BIBREF11 , but it only performed well on a binary classification problem. Another unsupervised learning based solution is the work by BIBREF12 , in which the authors proposed a set of criteria that a tweet should exhibit in order to be classified as offensive. They also showed that differences in geographic distribution of users have only marginal effect on the detection performance. Despite the above observation, we explore other features that might be possible to improve the detection accuracy in the solution outlined below.\nThe work by BIBREF5 applied a crowd-sourced solution to tackle hate-speech, with the creation of an additional dataset of annotations to extend the existing corpus. The impact of the experience of annotators in the classification performance was investigated. The work by BIBREF13 dealt with the classification problem of tweets, but their interest was on sexism alone, which they distinguished into `Hostile', `Benevolent' or `Other'. While the authors used the dataset of tweets from BIBREF12 , they treated the existing `Sexism' tweets as being of class `Hostile', while they collected their own tweets for the `Benevolent' class, on which they finally applied the FastText by BIBREF14 , and SVM classification.\n BIBREF15 approached the issue with a supervised learning model that is based on a neural network. Their method achieved higher score over the same dataset of tweets than any unsupervised learning solution known so far. That solution uses an LSTM model, with features extracted by character n-grams, and assisted by Gradient Boosted Decision Trees. Convolution Neural Networks (CNN) has also been explored as a potential solution in the hate-speech problem in tweets, with character n-grams and word2vec pre-trained vectors being the main tools. For example, BIBREF16 transformed the classification into a 2-step problem, where abusive text first is distinguished from the non-abusive, and then the class of abuse (Sexism or Racism) is determined. BIBREF17 employed pre-trained CNN vectors in an effort to predict four classes. They achieved slightly higher F-score than character n-grams.\nIn spite of the high popularity of NLP approaches in hate-speech classification BIBREF3 , we believe there is still a high potential for deep learning models to further contribute to the issue. At this point it is also relevant to note the inherent difficulty of the challenge itself, which can be clearly noted by the fact that no solution thus far has been able to obtain an F-score above 0.93.\nSimple word-based approaches, if used for blocking the posting of text or blacklisting users, not only fail to identify subtle offensive content, but they also affect the freedom of speech and expression.

        "evidence": "The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).\nOganesson (Og) is a synthetically produced highly radioactive element. Although IUPAC has used the term \"noble gas\" interchangeably with \"group 18\" and thus included oganesson, it may not be significantly chemically noble and is predicted to break the trend and be reactive due to relativistic effects. Because of the extremely short 0.7 ms half-life of its only known isotope, its chemistry has not yet been investigated.\nFor the first six periods of the periodic table, the noble gases are exactly the members of group 18. Noble gases are typically highly unreactive except when under particular extreme conditions. The inertness of noble gases makes them very suitable in applications where reactions are not wanted. For example, argon is used in incandescent lamps to prevent the hot tungsten filament from oxidizing; also, helium is used in breathing gas by deep-sea divers to prevent oxygen, nitrogen and carbon dioxide toxicity.\nThe properties of the noble gases can be well explained by modern theories of atomic structure: Their outer shell of valence electrons is considered to be \"full\", giving them little tendency to participate in chemical reactions, and it has been possible to prepare only a few hundred noble gas compounds. The melting and boiling points for a given noble gas are close together, differing by less than 10 °C (18 °F); that is, they are liquids over only a small temperature range.\nNeon, argon, krypton, and xenon are obtained from air in an air separation unit using the methods of liquefaction of gases and fractional distillation. Helium is sourced from natural gas fields that have high concentrations of helium in the natural gas, using cryogenic gas separation techniques, and radon is usually isolated from the radioactive decay of dissolved radium, thorium, or uranium compounds. Noble gases have several important applications in industries such as lighting, welding, and space exploration. A helium-oxygen breathing gas is often used by deep-sea divers at depths of seawater over 55 m (180 ft).

        "question": "What will affect the prediction of public speech?",
        "answer": "The speakers' reputations, popularity gained by publicity, etc.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe use a Causal Diagram to analyze and remove the effects of the data bias (e.g., the speakers’ reputations, popularity gained by publicity, etc.) in our prediction model.",

He defeated Denis Istomin, Dan Evans, and Taylor Fritz to reach the fourth round, where he faced 14th seed Stefanos Tsitsipas. In a stunning upset, Tsitsipas defeated Federer in four close sets. Critically, Federer was unable to convert any of the twelve break points he held throughout the match, including four set points in the second set. After the match Federer announced he would play the clay court season for the first time since 2016.\n\nAt the Dubai Tennis Championships Federer won his 100th Career Singles Title, beating Tsitsipas in straight sets in the final. It was his eighth title in Dubai and he became only the second man after Jimmy Connors to reach the three figure mark in the Open Era. Federer then reached the final of the 2019 Indian Wells Masters where he lost to Dominic Thiem in three sets. On 31 March, Federer defeated John Isner at the 2019 Miami Open in straights sets to win his 4th Miami Open title and 28th Masters title. Federer then played his first clay court tournament in three years at the 2019 Madrid Open and secured his 1200th career win, beating Gaël Monfils in the third round. In the quarterfinals he lost to Dominic Thiem again in three sets, despite having two match points in the second set. Federer then played at the Italian Open and reached the quarterfinals but was forced to withdraw from his quarterfinal match against Stefanos Tsitsipas due to a right leg injury.\n\nFederer next played at the French Open for the first time in 4 years and seeded 3rd in the draw. Federer achieved comfortable straight-set victories against Lorenzo Sonego, Oscar Otte, Casper Ruud and Leonardo Mayer to reach the quarterfinals, where he faced good friend and compatriot Stan Wawrinka. Federer managed to avenge his loss to Wawrinka at the same stage of the tournament 4 years ago, winning in 4 sets after 3 hours and 35 minutes. With the victory Federer returned to the semifinals of the French Open for the first time since 2012, where he lost to defending and 11-time champion Rafael Nadal in straight sets.\n\nFederer then began his grass court season at the Halle Open where he won his tenth title at the event, defeating David Goffin in the final in straight sets. This marked the first time Federer had won a singles tournament ten times or more. At Wimbledon, Roger Federer reached his record 12th final at the tournament after ousting his nemesis Rafael Nadal in four sets in the semifinal; thus, exacting revenge for his earlier defeat to him at the French Open. This was also the first time Federer played Nadal at Wimbledon since the 2008 Wimbledon final, a match regarded by some as the greatest match in the history of tennis. Federer then faced Novak Djokovic in the final, against whom he lost in a five set thriller lasting 4 hours and 57 minutes, despite having two championship points on serve in the fifth set. The match also marked the first time a fifth set tiebreaker was played at 12 games all in the men's singles and was the longest men's final in Wimbledon history.\n\nFederer next played at the 2019 Cincinnati Masters and reached the third round where he lost in straight sets to Andrey Rublev. This was his quickest defeat in 16 years, taking just 62 minutes. At the 2019 US Open, he was seeded third. He dropped the first set against both Sumit Nagal and Damir Džumhur in the first two rounds, but pulled out convincing straight sets wins over Dan Evans and David Goffin in the third and fourth. In the quarterfinals, he faced Grigor Dimitrov, who was ranked No. 78 going into the tournament. Despite taking a two sets to one lead, Federer ultimately lost the match in five sets. At the 2019 Shanghai Masters, Federer defeated David Goffin in straight sets to reach the quarterfinals. However, he lost the quarterfinal to Alexander Zverev in three sets.\n\nFederer advanced to the Swiss Indoors as the two-time defending champion. His first round match, against Peter Gojowczyk, was remarkable for being the 1500th match of his career. In the final, he defeated Alex de Minaur in straight sets for a record-extending tenth Swiss Indoors title. Federer then played in the Björn Borg group at the 2019 ATP Finals where in the round robin, he lost his opening match to Dominic Thiem in straight sets but beat Matteo Berrettini and Djokovic (his first win over Djokovic since 2015) in straight sets to qualify for the semifinals. He then lost the semifinal to Stefanos Tsitsipas in straight sets.\n\n2020: Australian Open semifinals and right knee surgery\nFederer began his 2020 season at the 2020 Australian Open. He reached the semifinals after straight sets wins over Steve Johnson and Filip Krajinović, a five-set win over John Millman and a four-set win over Márton Fucsovics. Federer saved seven match points in his five-set quarterfinal win over Tennys Sandgren. Federer then lost his semifinal match to Djokovic in straight sets, having sustained a groin injury earlier in the tournament. In February, Federer underwent arthroscopic surgery for a right knee injury and subsequently withdrew from the Dubai Championships, Indian Wells, Miami Open, and the French Open to give time for his knee to recover, announcing that he would return in the grass season. On 10 June, due to a setback from his initial rehabilitation from the knee injury suffered earlier in the year, Federer announced that he had to have an additional arthroscopic procedure on his right knee. He officially shut down his season to take the necessary time to recover, vowing to return in 2021. This was only the second year in Federer's career since he won his first title that he finished without a title.\n\n2021: Wimbledon quarterfinal and last singles match, injuries\nIn January, Federer withdrew from the 2021 Australian Open due to still recovering from knee surgery and strict COVID-19 quarantine measures in Australia. On 8 March, Novak Djokovic surpassed him for the most career weeks spent as the ATP number 1 ranked player. On 10 March, he made his return to the ATP Tour at the Qatar Open. He won his first ATP match in 14 months against Dan Evans, but lost to Nikoloz Basilashvili in the quarterfinals.\n\nFederer then played at the Geneva Open where he lost his opening match to Pablo Andújar in three sets. After defeating Dominik Koepfer of Germany in four sets in the third round, Federer advanced to the fourth round at the French Open. However, he withdrew from the tournament before his fourth-round match citing knee problems, giving a walkover to Matteo Berrettini of Italy.\n\nIn 2021 Halle Open where he was seeded fifth, he lost in the second round to Félix Auger-Aliassime. Federer was playing against the 20-year-old for the first time. Their 19-year age difference was the biggest in Federer's 1,521 career matches. This was the earliest exit at this tournament for Federer who was seeking his 70th match win in Halle, and his 18th quarterfinal at this event in as many appearances. At Wimbledon, 39-year-old Federer advanced to the quarterfinals and thus became the oldest Wimbledon quarterfinalist in the Open Era, breaking the record held by Ken Rosewall, following wins over Adrian Mannarino by retirement, Richard Gasquet, 29th seed Cameron Norrie, and 23rd seed Lorenzo Sonego. However, he was then upset by 14th seed Hubert Hurkacz in the quarterfinal in straight sets. This was the first time in 19 years at Wimbledon he had lost in straight sets, and only the second time he had lost a set 6–0 in the 21st century (the previous occasion was against Nadal in the 2008 French Open final).\n\nOn 15 August, Federer announced that he underwent another knee surgery after further injury during the grass court season. He withdrew from the US Open and stated that he would be off the tour for \"many months,\" but he hoped to make a return to the tour in 2022.\n\n2022: Retirement and farewell alongside rivals\nFederer did not play after Wimbledon 2021, and dropped out of the top 50 on 13 June 2022. On 11 July 2022, he became unranked for the first time since his professional debut.\n\nHowever, Federer announced that he was set to return to the tour at the 2022 Laver Cup in September. On 15 September 2022, he announced his impending retirement from professional tennis on the ATP Tour, noting that the Laver Cup would be his final ATP event. He stated that he \"will play more tennis in the future, of course, but just not in Grand Slams or on the tour.\" His final match resulted in a loss in doubles partnering long-time rival and friend Rafael Nadal, against Jack Sock and Frances Tiafoe.

        "evidence": "Automated deriving discourse relation from free text is a challenging but im-portant problem. The shallow discourse parsing is very useful in the text summariza-tion BIBREF0 , opinion analysis BIBREF1 and natural language generation. Shallow discourse parser is the system of parsing raw text into a set of discourse relations between two adjacent or non-adjacent text spans. Discourse relation is composed of a discourse connective, two arguments of the discourse connective and the sense of the discourse connective. Discourse connective signals the explicit dis-course relation, but in non-explicit discourse relation, a discourse connective is omit-ted. Two arguments of the discourse connective, Arg1 and Arg2, which are the two adjacent or non-adjacent text spans connecting in the discourse relation. The sense of the discourse connective characterizes the nature of the discourse relations. The following discourse relation annotation is taken from the document in the PDTB. Arg1 is shown in italicized, and Arg2 is shown in bold. The discourse connective is underlined.\nThe connective identifier finds the connective word, “unless”. The arguments identifier locates the two arguments of “unless”. The sense classifier labels the dis-course relation. The non-explicit identifier checks all the pair of adjacent sentences. If the non-explicit identifier indentifies the pair of sentences as non-explicit relation, it will label it the relation sense. Though many research work BIBREF2 , BIBREF3 , BIBREF4 are committed to the shallow discourse parsing field, all of them are focus on the subtask of parsing only rather than the whole parsing process. Given all that, a full shallow discourse parser framework is proposed in our paper to turn the free text into discourse relations set. The parser includes connective identifier, arguments identifier, sense classifier and non-explicit identifier, which connects with each other in pipeline. In order to enhance the performance of the parser, the feature-based maximum entropy model approach is adopted in the experiment. Maximum entropy model offers a clean way to combine diverse pieces of contextual evidence in order to estimate the probability of a certain linguistic class occurring with a certain linguistic context in a simple and accessible manner. The three main contributions of the paper are:\nThe rest of this paper is organized as follows. Section 2 reviews related work in discourse parsing. Section 3 describes the experimental corpus–PDTB.

        "answer": "The dataset contains 700K example pairs and has a vocabulary of around 400K words.",
        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nWe experiment with the WIKIBIO dataset (Lebret et al., 2016) which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words.",

The musical starts with a press conference, where Keane explains his proof to reporters and promises to return to normal life with his wife Anna and his family. After promising to Anna that he is now \"done with Fermat\", Keane is surprised in his study by none other than Fermat himself. Keane asks Fermat for the secret of his proof but is refused. Instead, Fermat introduces him to the \"Aftermath\", a \"heavenly purgatory\" where he meets the famous mathematicians Euclid, Pythagoras, Newton, and Gauss. They inform him that his proof contains a \"big fat hole\". In a second press conference, Keane is questioned by reporters about a flaw in the proof. Anna wishes for a corrected proof for her birthday. Fermat mocks Keane, and the other mathematicians inform him that \"mathematics is a young man's game\". Keane returns to his attic to try to fix his proof, while his \"math widow\" wife is frustrated. Fermat continues to taunt Keane, but he is invisible and inaudible to Anna, and the three dance a \"bizarre tango à trois\" while Anna is confused by Keane talking to Fermat. The other mathematicians from the Aftermath, after noticing that they can't keep up with the mathematics of the past century, decide to grant admission to Keane even if he is unable to prove the theorem. As Keane finally gives up and declares his attempts a failure, Anna suggests that \"within your failure lie the seeds of your success\", repeating a line earlier spoken by the mathematicians. This quickly leads to Keane realising how to close the gap in the argument, and the musical ends with another press conference, and Fermat congratulates Keane for his proof.",

        "question": "What is structural genomics?",
        "evidence": "",
        "answer": "Structural genomics seeks to describe the 3-dimensional structure of every protein encoded by a given genome. This genome-based approach allows for a high-throughput method of structure determination by a combination of experimental and modeling approaches. The principal difference between structural genomics and traditional structural prediction is that structural genomics attempts to determine the structure of every protein encoded by the genome, rather than focusing on one particular protein. With full-genome sequences available, structure prediction can be done more quickly through a combination of experimental and modeling approaches, especially because the availability of large number of sequenced genomes and previously solved protein structures allows scientists to model protein structure on the structures of previously solved homologs.\n\nBecause protein structure is closely linked with protein function, the structural genomics has the potential to inform knowledge of protein function. In addition to elucidating protein functions, structural genomics can be used to identify novel protein folds and potential targets for drug discovery. Structural genomics involves taking a large number of approaches to structure determination, including experimental methods using genomic sequences or modeling-based approaches based on sequence or structural homology to a protein of known structure or based on chemical and physical principles for a protein with no homology to any known structure.\n\nAs opposed to traditional structural biology, the determination of a protein structure through a structural genomics effort often (but not always) comes before anything is known regarding the protein function. This raises new challenges in structural bioinformatics, i.e. determining protein function from its 3D structure.\n\nStructural genomics emphasizes high throughput determination of protein structures. This is performed in dedicated centers of structural genomics.\n\nWhile most structural biologists pursue structures of individual proteins or protein groups, specialists in structural genomics pursue structures of proteins on a genome wide scale. This implies large-scale cloning, expression and purification. One main advantage of this approach is economy of scale. On the other hand, the scientific value of some resultant structures is at times questioned. A Science article from January 2006 analyzes the structural genomics field.\n\nOne advantage of structural genomics, such as the Protein Structure Initiative, is that the scientific community gets immediate access to new structures, as well as to reagents such as clones and protein. A disadvantage is that many of these structures are of proteins of unknown function and do not have corresponding publications. This requires new ways of communicating this structural information to the broader research community. The Bioinformatics core of the Joint center for structural genomics (JCSG) has recently developed a wiki-based approach namely Open protein structure annotation network (TOPSAN) for annotating protein structures emerging from high-throughput structural genomics centers.",

        "question": "Does applying Reinforcement Learning lead to higher scores on the three automatic metrics?",
        "answer": "No, it doesn't.",
        "evidence": "The experimental results of the detection task and the generative intervention task are shown in Table TABREF27 and Table TABREF29 separately. The results of the human evaluation are shown in Table TABREF30. Figure FIGREF25 shows examples of the generated responses.\nAs shown in Table TABREF27 and TABREF29, all the classification and generative models perform better on the Gab dataset than on the Reddit dataset. We think this stems from the datasets' characteristics. First, the Gab dataset is larger and has a more balanced category distribution than the Reddit dataset. Therefore, it is inherently more challenging to train a classifier on the Reddit dataset. Further, the average lengths of the Reddit posts and conversations are much larger than those of Gab, potentially making the Reddit input nosier than the Gab input for both tasks. On both the Gab and Reddit datasets, the SVM classifier and the LR classifier achieved better performance than the CNN and RNN model with randomly initialized word embeddings. A possible reason is that without pretrained word embeddings, the neural network models tend to overfit on the dataset.\nFor the generative intervention task, three models perform similarly on all three automatic evaluation metrics. As expected, the Seq2Seq model achieves higher scores with filtered conversation as input. However, this is not the case for the VAE model. This indicates that the two models may have different capabilities to capture important information in conversations.\nAs shown in Table TABREF29, applying Reinforcement Learning does not lead to higher scores on the three automatic metrics. However, human evaluation (Table TABREF30) shows that the RL model creates responses that are potentially better at mitigating hate speech and are more diverse, which is consistent with BIBREF21. There is a larger performance difference with the Gab dataset, while the effectiveness and the diversity of the responses generated by the Seq2Seq model and the RL model are quite similar on the Reddit dataset. One possible reason is that the size of the training data from Reddit (around 8k) is only 30% the size of the training data from Gab. The inconsistency between the human evaluation results and the automatic ones indicates the automatic evaluation metrics listed in Table TABREF29 can hardly reflect the quality of the generated responses. As mentioned in Section SECREF4, annotators tend to have strategies for intervention. Therefore, generating the common parts of the most popular strategies for all the testing input can lead to high scores of these automatic evaluation metrics. For example, generating “Please do not use derogatory language.” for all the testing Gab data can achieve 4.2 on BLEU, 20.4 on ROUGE, and 18.2 on METEOR. However, this response is not considered as high-quality because it is almost a universal response to all the hate speech, regardless of the context and topic.\nSurprisingly, the responses generated by the VAE model have much worse diversity than the other two methods according to human evaluation. As indicated in Figure FIGREF25, the responses generated by VAE tend to repeat the responses related to some popular hate keyword. For example, “Use of the r-word is unacceptable in our discourse as it demeans and insults people with mental disabilities.” and “Please do not use derogatory language for intellectual disabilities.” are the generated responses for a large part of the Gab testing data. According to Figure FIGREF20, insults towards disabilities are the largest portion in the dataset, so we suspect that the performance of the VAE model is affected by the imbalanced keyword distribution.\nThe sampled results in Figure FIGREF25 show that the Seq2Seq and the RL model can generate reasonable responses for intervention. However, as is to be expected with machine-generated text, in the other human evaluation we conducted, where Mechanical Turk workers were also presented with sampled human-written responses alongside the machine generated responses, the human-written responses were chosen as the most effective and diverse option a majority of the time (70% or more) for both datasets. This indicates that there is significant room for improvement while generating automated intervention responses.\nIn our experiments, we only utilized the text of the posts, but more information is available and can be utilized, such as the user information and the title of a Reddit submission.\nAs shown in Table 3, applying Reinforcement Learning does not lead to higher scores on the three automatic metrics.",

At their closest point to the African mainland, they are 100 kilometres (62 miles) west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and are the most populous special territory of the European Union.\n\nThe seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including Garachico and Anaga. In ancient times, the island chain was often referred to as \"the Fortunate Isles\". The Canary Islands are the southernmost region of Spain, and the largest and most populous archipelago of Macaronesia. Because of their location, the Canary Islands have historically been considered a link between the four continents of Africa, North America, South America, and Europe.\n\nIn 2019, the Canary Islands had a population of 2,153,389, with a density of 287.39 inhabitants per km2, making it the eighth most populous autonomous community of Spain. The population is mostly concentrated in the two capital islands: around 43% on the island of Tenerife and 40% on the island of Gran Canaria.\n\nThe Canary Islands, especially Tenerife, Gran Canaria, Fuerteventura, and Lanzarote, are a major tourist destination, with over 12 million visitors per year. This is due to their beaches, subtropical climate, and important natural attractions, especially Maspalomas in Gran Canaria and Mount Teide (a World Heritage Site) in Tenerife. Mount Teide is the highest peak in Spain and the third tallest volcano in the world, measured from its base on the ocean floor. The islands have warm summers and winters warm enough for the climate to be technically tropical at sea level. The amount of precipitation and the level of maritime moderation vary depending on location and elevation. The archipelago includes green areas as well as desert. The islands' high mountains are ideal for astronomical observation, because they lie above the temperature inversion layer. As a result, the archipelago boasts two professional observatories: the Teide Observatory on Tenerife, and Roque de los Muchachos Observatory on La Palma.",

        "question": "What model do they use as the feature extractor?",
        "answer": "The x-vector model.",
        "evidence": "Recent advances in Machine Learning (ML) and, in particular, in Deep Neural Networks (DNN) have allowed the development of highly accurate predictive systems for numerous applications. Among others, health has received significant attention due to the potential of ML-based diagnostic, monitoring and therapeutic systems, which are fast (when compared to traditional diagnostic processes), easily distributed and cheap to implement (many such systems can be executed in mobile devices). Furthermore, these systems can incorporate biometric data to perform non-invasive diagnostics.\nAmong other data types, speech has been proposed as a valuable biomarker for the detection of a myriad of diseases, including: neurological conditions, such as Alzheimer’s BIBREF0, Parkinson’s disease (PD) BIBREF1 and Amyotrophic Lateral Sclerosis BIBREF2; mood disorders, such as depression, anxiety BIBREF3 and bipolar disorder BIBREF4; respiratory diseases, such as obstructive sleep apnea (OSA) BIBREF5. However, temporal and financial constraints, lack of awareness in the medical community, ethical issues and patient-privacy laws make the acquisition of medical data one of the greatest obstacles to the development of health-related speech-based classifiers, particularly for deep learning models. For this reason, most systems rely on knowledge-based (KB) features, carefully designed and selected to model disease symptoms, in combination with simple machine learning models (e.g. Linear classifiers, Support Vector Machines). KB features may not encompass subtler symptoms of the disease, nor be general enough to cover varying levels of severity of the disease. To overcome this limitation, some works have instead focused on speaker representation models, such as Gaussian Supervectors and i-vectors. For instance, Garcia et al. BIBREF1 proposed the use of i-vectors for PD classification and Laaridh et al. BIBREF6 applied the i-vector paradigm to the automatic prediction of several dysarthric speech evaluation metrics like intelligibility, severity, and articulation impairment. The intuition behind the use of these representations is the fact that these algorithms model speaker variability, which should include disease symptoms BIBREF1.\nProposed by Snyder et al., x-vectors are discriminative deep neural network-based speaker embeddings, that have outperformed i-vectors in tasks such as speaker and language recognition BIBREF7, BIBREF8, BIBREF9. Even though it may not be evident that discriminative data representations are suitable for disease detection when trained with general datasets (that do not necessarily include diseased patients), recent works have shown otherwise. X-vectors have been successfully applied to paralinguistic tasks such as emotion recognition BIBREF10, age and gender classification BIBREF11, the detection of obstructive sleep apnea BIBREF12 and as a complement to the detection of Alzheimer's Disease BIBREF0. Following this line of research, in this work we study the hypothesis that speaker characteristics embedded in x-vectors extracted from a single network, trained for speaker identification using general data, contain sufficient information to allow the detection of multiple diseases. Moreover, we aim to assess if this information is kept even when language mismatch is present, as has already been shown to be true for speaker recognition BIBREF8. In particular, we use the x-vector model as a feature extractor, to train Support Vector Machines for the detection of two speech-affecting diseases: Parkinson's disease (PD) and obstructive sleep apnea (OSA).\nPD is the second most common neurodegenerative disorder of mid-to-late life after Alzheimer’s disease BIBREF13, affecting 1% of people over the age of 65. Common symptoms include bradykinesia (slowness or difficulty to perform movements), muscular rigidity, rest tremor, as well as postural and gait impairment. 89% of PD patients develop also speech disorders, typically hypokinetic dysarthria, which translates into symptoms such as reduced loudness, monoloudness, monopitch, hypotonicity, breathy and hoarse voice quality, and imprecise articulation BIBREF14BIBREF15.\nOSA is a sleep-concerned breathing disorder characterized by a complete stop or decrease of the airflow, despite continued or increased inspiratory efforts BIBREF16. This disorder has a prevalence that ranges from 9% to 38% through different populations BIBREF17, with higher incidence in male and elderly groups. OSA causes mood and personality changes, depression, cognitive impairment, excessive daytime sleepiness, thus reducing the patients' quality of life BIBREF18, BIBREF19. It is also associated with diabetes, hypertension and cardiovascular diseases BIBREF16, BIBREF20. Moreover, undiagnosed sleep apnea can have a serious economic impact, having had an estimated cost of $\\$150$ billion in the U.S, in 2015 BIBREF21. Considering the prevalence and serious nature of the two diseases described above, speech-based technology that tests for their existence has the potential to become a key tool for early detection, monitoring and prevention of these conditions BIBREF22.\nThe remainder of this document is organized as follows. Section SECREF2 presents the background concepts on speaker embeddings, and in particular on x-vectors. Section SECREF3 introduces the experimental setup: the corpora, the tasks, the KB features and the speaker embeddings employed. The results are presented and discussed in section SECREF4. Finally, section SECREF5 summarizes the main conclusions and suggests possible directions for future work.\nIn particular, we use the x-vector model as a feature extractor, to train Support Vector Machines for the detection of two speech-affecting diseases: Parkinson's disease (PD) and obstructive sleep apnea (OSA).",

The other two schemes directly access the sentence-level contexts of the concepts.\nNearest neighbors (NN) Estimator: We used the pre-trained GloVe embeddings BIBREF11 of concepts to implement a nearest-neighbor estimator as follows. Given a concept $c$, we extract all labeled concepts within a given radius $r$ (cosine similarity $0.3$). In one variant, $c$'s controversiality score is taken to be the fraction of controversial concepts among them. In another variant, labeled concepts are weighted by their cosine similarity to $c$.\nNaive Bayes (NB) Estimator: A Naive Bayes model was learned, with a bag-of-words feature set, using the word counts in the sentences of our training data – the contexts of the controversial and non-controversial concepts. The controversiality score of a concept $c$ for its occurrence in a sentence $s$, is taken as the posterior probability (according to the NB model) of $s$ to contain a controversial concept, given the words of $s$ excluding $c$, and taking a prior of $0.5$ for controversiality (as is the case in the datasets). The controversiality score of $c$ is then defined as the average score over all sentences referencing $c$.\nRecurrent neural network (RNN): A bidirectional RNN using the architecture suggested in BIBREF10 was similarly trained. The network receives as input a concept and a referring sentence, and outputs a score.

        "answer": "LSTMRNN and GRURNN.",
        "evidence": "Modeling temporal and sequential data, which is crucial in machine learning, can be applied in many areas, such as speech and natural language processing. Deep neural networks (DNNs) have garnered interest from many researchers after being successfully applied in image classification BIBREF0 and speech recognition BIBREF1 . Another type of neural network, called a recurrent neural network (RNN) is also widely used for speech recognition BIBREF2 , machine translation BIBREF3 , BIBREF4 and language modeling BIBREF5 , BIBREF6 . RNNs have achieved many state-of-the-art results. Compared to DNNs, they have extra parameters for modeling the relationships of previous or future hidden states with current input where the RNN parameters are shared for each input time-step.\nGenerally, RNNs can be separated by a simple RNN without gating units, such as the Elman RNN BIBREF7 , the Jordan RNN BIBREF8 , and such advanced RNNs with gating units as the Long-Short Term Memory (LSTM) RNN BIBREF9 and the Gated Recurrent Unit (GRU) RNN BIBREF4 . A simple RNN usually adequate to model some dataset and a task with short-term dependencies like slot filling for spoken language understanding BIBREF10 . However, for more difficult tasks like language modeling and machine translation where most predictions need longer information and a historical context from each sentence, gating units are needed to achieve good performance. With gating units for blocking and passing information from previous or future hidden layer, we can learn long-term information and recursively backpropagate the error from our prediction without suffering from vanishing or exploding gradient problems BIBREF9 . In spite of this situation, the concept of gating mechanism does not provide an RNN with a more powerful way to model the relation between the current input and previous hidden layer representations.\nMost interactions inside RNNs between current input and previous (or future) hidden states are represented using linear projection and addition and are transformed by the nonlinear activation function. The transition is shallow because no intermediate hidden layers exist for projecting the hidden states BIBREF11 . To get a more powerful representation on the hidden layer, Pascanu et al. BIBREF11 modified RNNs with an additional nonlinear layer from input to the hidden layer transition, hidden to hidden layer transition and also hidden to output layer transition. Socher et al. BIBREF12 , BIBREF13 proposed another approach using a tensor product for calculating output vectors given two input vectors. They modified a Recursive Neural Network (RecNN) to overcome those limitations using more direct interaction between two input layers. This architecture is called a Recursive Neural Tensor Network (RecNTN), which uses a tensor product between child input vectors to represent the parent vector representation. By adding the tensor product operation to calculate their parent vector, RecNTN significantly improves the performance of sentiment analysis and reasoning on entity relations tasks compared to standard RecNN architecture. However, those models struggle to learn long-term dependencies because the do not utilize the concept of gating mechanism.\nIn this paper, we proposed a new RNN architecture that combine the gating mechanism and tensor product concepts to incorporate both advantages in a single architecture. Using the concept of such gating mechanisms as LSTMRNN and GRURNN, our proposed architecture can learn temporal and sequential data with longer dependencies between each input time-step than simple RNNs without gating units and combine the gating units with tensor products to represent the hidden layer with more powerful operation and direct interaction. Hidden states are generated by the interaction between current input and previous (or future) hidden states using a tensor product and a non-linear activation function allows more expressive model representation. We describe two different models based on LSTMRNN and GRURNN. LSTMRNTN is our proposed model for the combination between a LSTM unit with a tensor product inside its cell equation and GRURNTN is our name for a GRU unit with a tensor product inside its candidate hidden layer equation.\nIn Section \"Background\" , we provide some background information related to our research.

These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification.",

Successfully understanding, participating or communicating with others in these situations presupposes some form of reasoning: about individual sentences, whole paragraphs of legal documents, small or bigger pieces of dialogue and so on. The human reasoning performed in these different situations cannot be explained by a single rigid system of reasoning, plainly because reasoning is performed in different ways in each one of them. Consider the following example:\nThree representatives are needed.\nIf a human reasoner with expert knowledge was to interpret the above utterance in a legal context, s/he will most probably judge that a situation where more than three references are provided could be compatible with the semantics of the utterance. To the contrary, if the same reasoner was to interpret the above as part of a casual, everyday conversation, then three would most likely be interpreted as exactly three, making the same situation incompatible with the utterance. In this paper, we want to focus on precise inference, inference which is either performed by experts or normal people after taking some time to consider the inferences that follow or not from a set of premises. The problem one encounters in testing systems of this type of reasoning is the fact that no large scale datasets of this sort of inference exist.

        "evidence": "Incorporating Document Features ::: Learning Phase ::: Feature Extraction ::: Document-unaware Features\nOrdinal position: It is shown that inclusion of sentence, in summary, is relevant to its position in the document or even in a paragraph. Intuitively, sentences at the beginning or the end of a text are more likely to be included in the summary. Depending on how it is defined, this feature might be document-unaware or not. For example, in BIBREF29 and BIBREF37 it is defined as $\\frac{5}{5}$ for the first sentence, $\\frac{4}{5}$ for the second, and so on to $\\frac{1}{5}$ for fifth and zero for remaining sentences. In another research conducted by Wong et al. BIBREF9, it is defined as $\\frac{1}{sentence\\ number}$. With such a definition, we may have several sentences, for example, with position=$\\frac{1}{5}$ in the training set, these may not have the same sense of position. While a sentence position=$\\frac{1}{5}$ means “among the firsts” in a document with 40 sentences, it has a totally different meaning of “in the middle”, in another document containing 10 sentences. Thus, a useful feature formula should involve differences of documents which may change the meaning of information within it. In our experiments, we used the definition of BIBREF9. A document-aware version of position will be introduced in (SECREF6).\nLength of sentence: the intuition behind this feature is that sentences of too long or too short length are less likely to be included in the summary. Like sentence position, this feature is also subject to the wrong definition that makes it document-unaware. For example, in BIBREF9 it is defined as a number of words in a sentence. Such a definition does not take into account that a sentence with, say 15 words may be considered long if all other sentences of document have fewer words. Another sentence with the same number of words may be regarded as short, because other sentences in that document have more than 15 words. This might occur due to different writing styles. However, we included this in our experiments to compare its effect with that of its document-aware counterpart, which will be listed in (SECREF6).\nThe Ratio of Nouns: is defined in BIBREF30 as the number of nouns divided by total number of words in the sentence, after stop-words are removed. Three other features, Ratio of Verbs, Ratio of Adjectives, and Ratio of Adverbs are defined in the same manner and proved to have a positive effect on ranking performance. From our perspective, however, a sentence with a ratio of nouns =0.5, for example, in a document containing many nouns, must be discriminated in the training set from another sentence with the same ratio of nouns, that appeared in another document having fewer nouns. This feature does not represent how many nouns are there in the document, which is important in sentence ranking. The same discussion goes on to justify the need to consider the number of verbs, adjectives, and adverbs in the document. The impact of these features is examined in our experiments and compared to that of their document-aware counterparts.\nThe Ratio of Numerical entities: assuming that sentences containing more numerical data are probably giving us more information, this feature may help us in ranking BIBREF31, BIBREF32. For calculation, we count the occurrences of numbers and digits proportional to the length of sentence. This feature must be less weighted if almost all sentences of a document have numerical data. However, it does not count numbers and digits in other sentences of the document.\nCue Words: if a sentence contains special phrases such as “in conclusion”, “overall”, “to summarize”, “in a nutshell” and so forth, its selection as a part of the summary is more probable than others. The number of these phrases is counted for this feature.\nIncorporating Document Features ::: Learning Phase ::: Feature Extraction ::: Document-aware Features\nCosine position: As mentioned in (SECREF5) a good definition of position should take into account document length. A well-known formula used in the literature BIBREF38, BIBREF7 is\nin which index is an integer representing the order of sentences and T is the total number of sentences in document. This feature ranges from 0 to 1, the closer to the beginning or to the end, the higher value this feature will take. $\\alpha $ is a tuning parameter. As it increases, the value of this feature will be distributed more equally over sentences. In this manner, equal values of this feature in the training set represent a uniform notion of position in a document, so it becomes document-aware.\nRelative Length: the intuition behind this feature is explained in (SECREF5). A discussion went there that a simple count of words does not take into account that a sentence with a certain number of words may be considered long or short, based on the other sentences appeared the document. Taking this into consideration, we divided the number of words in the sentence by the average length of sentences in the document. More formally, the formula is:\nin which n is number of sentences in the document and $s_i$ is the i’th sentence of it. Values greater than 1 could be interpreted as long and vice versa.\nTF-ISF: this feature counts the frequency of terms in a document and assigns higher values to sentences having more frequent terms. It also discounts terms which appear in more sentences. Since it is well explained in the literature, we have not included details and formula which are in references BIBREF34 and BIBREF39. Nonetheless, the aspect that matters in our discussion is that both frequency and inverse sentence frequency are terms which involve properties of context, and consequently are document-aware.\nPOS features: Here we introduce another way to include the ratio of part of speech (POS) units in features and keep them document-normalized. To do this, the number of occurrences of each POS unit should be divided by the number of them in the document, instead of that occurring in a sentence. The formal definition of the new document-aware features are as follows:\nIncorporating Document Features ::: Learning Phase ::: Feature Extraction ::: Explicit Document Features\nIn order to further investigate how effective are document specific features in sentence ranking, we defined several features for documents. These features are then calculated for each document and repeated in the feature vector of every sentence of that document. Their formal definition is described below and their effect is examined in the result and discussion section (SECREF5):\nDocument sentences: An important property of a document that affects summarization is the total number of sentences participating in sentence ranking. As this number grows, a summarizer should be more selective and precise. Also, some sentence features such as cue words, maybe more weighted for longer documents. In addition, the main contextual information is probably more distributed over sentences. In such a case even lower values of other features should be considered important.\nDocument words: the number of words in the document is another notion of document length. Since the number of sentences alone is not enough to represent document length, this feature should also be considered.\nTopical category: different topics such as political, economic, etc. have different writing styles and this might affect sentence ranking. For instance, numerical entities may appear more in economic or sport reports than in religious or social news. Therefore the weight of this attribute should be more or less, based on a document’s category. So it needs to be included.\nIncorporating Document Features ::: Learning Phase ::: Feature Extraction ::: Document-unaware Features\nOrdinal position: It is shown that inclusion of sentence, in summary, is relevant to its position in the document or even in a paragraph. Intuitively, sentences at the beginning or the end of a text are more likely to be included in the summary. Depending on how it is defined, this feature might be document-unaware or not. For example, in BIBREF29 and BIBREF37 it is defined as $\\frac{5}{5}$ for the first sentence, $\\frac{4}{5}$ for the second, and so on to $\\frac{1}{5}$ for fifth and zero for remaining sentences. In another research conducted by Wong et al. BIBREF9, it is defined as $\\frac{1}{sentence\\ number}$. With such a definition, we may have several sentences, for example, with position=$\\frac{1}{5}$ in the training set, these may not have the same sense of position. While a sentence position=$\\frac{1}{5}$ means “among the firsts” in a document with 40 sentences, it has a totally different meaning of “in the middle”, in another document containing 10 sentences. Thus, a useful feature formula should involve differences of documents which may change the meaning of information within it. In our experiments, we used the definition of BIBREF9. A document-aware version of position will be introduced in (SECREF6).\n\nLength of sentence: the intuition behind this feature is that sentences of too long or too short length are less likely to be included in the summary. Like sentence position, this feature is also subject to the wrong definition that makes it document-unaware. For example, in BIBREF9 it is defined as a number of words in a sentence. Such a definition does not take into account that a sentence with, say 15 words may be considered long if all other sentences of document have fewer words. Another sentence with the same number of words may be regarded as short, because other sentences in that document have more than 15 words. This might occur due to different writing styles. However, we included this in our experiments to compare its effect with that of its document-aware counterpart, which will be listed in (SECREF6).\n\nThe Ratio of Nouns: is defined in BIBREF30 as the number of nouns divided by total number of words in the sentence, after stop-words are removed. Three other features, Ratio of Verbs, Ratio of Adjectives, and Ratio of Adverbs are defined in the same manner and proved to have a positive effect on ranking performance. From our perspective, however, a sentence with a ratio of nouns =0.5, for example, in a document containing many nouns, must be discriminated in the training set from another sentence with the same ratio of nouns, that appeared in another document having fewer nouns. This feature does not represent how many nouns are there in the document, which is important in sentence ranking. The same discussion goes on to justify the need to consider the number of verbs, adjectives, and adverbs in the document. The impact of these features is examined in our experiments and compared to that of their document-aware counterparts.\n\nThe Ratio of Numerical entities: assuming that sentences containing more numerical data are probably giving us more information, this feature may help us in ranking BIBREF31, BIBREF32. For calculation, we count the occurrences of numbers and digits proportional to the length of sentence. This feature must be less weighted if almost all sentences of a document have numerical data. However, it does not count numbers and digits in other sentences of the document.\n\nCue Words: if a sentence contains special phrases such as “in conclusion”, “overall”, “to summarize”, “in a nutshell” and so forth, its selection as a part of the summary is more probable than others. The number of these phrases is counted for this feature.\n\nIncorporating Document Features ::: Learning Phase ::: Feature Extraction ::: Document-aware Features\nCosine position: As mentioned in (SECREF5) a good definition of position should take into account document length. A well-known formula used in the literature BIBREF38, BIBREF7 is\n\nin which index is an integer representing the order of sentences and T is the total number of sentences in document. This feature ranges from 0 to 1, the closer to the beginning or to the end, the higher value this feature will take. $\\alpha $ is a tuning parameter. As it increases, the value of this feature will be distributed more equally over sentences. In this manner, equal values of this feature in the training set represent a uniform notion of position in a document, so it becomes document-aware.\n\nRelative Length: the intuition behind this feature is explained in (SECREF5). A discussion went there that a simple count of words does not take into account that a sentence with a certain number of words may be considered long or short, based on the other sentences appeared the document. Taking this into consideration, we divided the number of words in the sentence by the average length of sentences in the document. More formally, the formula is:\n\nin which n is number of sentences in the document and $s_i$ is the i’th sentence of it. Values greater than 1 could be interpreted as long and vice versa.\n\nTF-ISF: this feature counts the frequency of terms in a document and assigns higher values to sentences having more frequent terms. It also discounts terms which appear in more sentences. Since it is well explained in the literature, we have not included details and formula which are in references BIBREF34 and BIBREF39. Nonetheless, the aspect that matters in our discussion is that both frequency and inverse sentence frequency are terms which involve properties of context, and consequently are document-aware.\n\nPOS features: Here we introduce another way to include the ratio of part of speech (POS) units in features and keep them document-normalized. To do this, the number of occurrences of each POS unit should be divided by the number of them in the document, instead of that occurring in a sentence. The formal definition of the new document-aware features are as follows:\n\nIncorporating Document Features ::: Learning Phase ::: Feature Extraction ::: Explicit Document Features\nIn order to further investigate how effective are document specific features in sentence ranking, we defined several features for documents. These features are then calculated for each document and repeated in the feature vector of every sentence of that document.

The Abbasid caliphs gave the title wazir to a minister formerly called katib (secretary), who was at first merely a helper but afterwards became the representative and successor of the dapir (official scribe or secretary) of the Sassanian kings.\n\nIn modern usage, the term has been used for government ministers in much of the Middle East and beyond.\n\nSeveral alternative spellings are used in English, such as vizir, wazir, and vezir.\n\nVizier is suggested to be an Iranian word, from the Pahlavi root of vičir, which originally had the meaning of a decree, mandate, and command, but later as its use in Dinkard also suggests, came to mean judge or magistrate. Arthur Jeffery considers the word to be a \"good Iranian\" word, as it has a well-established root in Avestan language. The Pahlavi vičir, is in fact from the Avestan vīčira, which means deciding. This Avestan root is behind the Modern Persian form of the word which is večer which means judge. This etymology is also supported by Johnny Cheung and Richard Nelson Frye\n\nAnother possibility is that the etymology of the word is derived from the Arabic wazara (\"to bear a burden\"), from the Semitic root W-Z-R. The word is mentioned in the Quran, where Aaron is described as the wazir (helper) of Moses, as well as the word wizr (burden) which is also derived from the same root. It was later adopted as a title, in the form of wazīr āl Muḥammad (\"Helper of the Family of Muhammad\") by the proto-Shi'a leaders al-Mukhtar and Abu Salama.

To what extent does it capture syntax-sensitive structures?\nRecent work examines the extent to which RNN-based models capture syntax-sensitive phenomena that are traditionally taken as evidence for the existence in hierarchical structure. In particular, in BIBREF1 we assess the ability of LSTMs to learn subject-verb agreement patterns in English, and evaluate on naturally occurring wikipedia sentences. BIBREF2 also consider subject-verb agreement, but in a “colorless green ideas” setting in which content words in naturally occurring sentences are replaced with random words with the same part-of-speech and inflection, thus ensuring a focus on syntax rather than on selectional-preferences based cues. BIBREF3 consider a wider range of syntactic phenomena (subject-verb agreement, reflexive anaphora, negative polarity items) using manually constructed stimuli, allowing for greater coverage and control than in the naturally occurring setting.\nThe BERT model is based on the “Transformer” architecture BIBREF4 , which—in contrast to RNNs—relies purely on attention mechanisms, and does not have an explicit notion of word order beyond marking each word with its absolute-position embedding. This reliance on attention may lead one to expect decreased performance on syntax-sensitive tasks compared to RNN (LSTM) models that do model word order directly, and explicitly track states across the sentence. Indeed, BIBREF5 finds that transformer-based models perform worse than LSTM models on the BIBREF1 agreement prediction dataset. In contrast, BIBREF6 find that self-attention performs on par with LSTM for syntax sensitive dependencies in the context of machine-translation, and performance on syntactic tasks is correlated with the number of attention heads in multi-head attention.\nI adapt the evaluation protocol and stimuli of BIBREF1 , BIBREF2 and BIBREF3 to the bidirectional setting required by BERT, and evaluate the pre-trained BERT models (both the Large and the Base models). Surprisingly (at least to me), the out-of-the-box models (without any task-specific fine-tuning) perform very well on all the syntactic tasks.\nIndeed, Tran et al.

Convolutional neural networks (CNNs) and recurrent neural networks (RNNs) especially Long Short-term Memory Network (LSTM), are used wildly in natural language processing tasks. With increasing datas, these two methods can reach considerable performance by requiring only limited domain knowledge and easy to be finetuned to specific applications at the same time.\nCNNs, which have the ability of capturing local correlations of spatial or temporal structures, have achieved excellent performance in computer vision and NLP tasks. And recently the emerge of some new techniques, such as Inception module BIBREF8 , Batchnorm BIBREF9 and Residual Network BIBREF3 have also made the performance even better. For sentence modeling, CNNs perform excellently in extracting n-gram features at different positions of a sentence through convolutional filters.\nRNNs, with the ability of handling sequences of any length and capturing long-term dependencies, , have also achieved remarkable results in sentence or document modeling tasks. LSTMs BIBREF10 were designed for better remembering and memory accesses, which can also avoid the problem of gradient exploding or vanishing in the standard RNN. Be capable of incorporating context on both sides of every position in the input sequence, BLSTMs introduced in BIBREF11 , BIBREF12 have reported to achieve great performance in Handwriting Recognition BIBREF13 , and Machine Translation BIBREF14 tasks.\nGenerative adversarial networks (GANs) BIBREF15 are a class of generative models for learning how to produce images. Basically, GANs consist of a generator G and a discriminator D, which are trained based on game theory. G maps a input noise vector to an output image, while D takes in an image then outputs a prediction whether the input image is a sample generated by G. Recently, applications of GANs have shown that they can generate promising results BIBREF16 , BIBREF17 . Several recent papers have also extended GANs to the semi-supervised context BIBREF18 , BIBREF19 by simply increasing the dimension of the classifier output from INLINEFORM0 to INLINEFORM1 , which the samples of the extra class are generated by G.\nIn this paper, We proposed an end-to-end architecture named AC-BLSTM by combining the ACNN with the BLSTM for sentences and documents modeling. In order to make the model deeper, instead of using the normal convolution, we apply the technique proposed in BIBREF8 which employs a INLINEFORM0 convolution followed by a INLINEFORM1 convolution by spatial factorizing the INLINEFORM2 convolution. And we use the pretrained word2vec vectors BIBREF20 as the ACNN input, which were trained on 100 billion words of Google News to learn the higher-level representations of n-grams. The outputs of the ACNN are organized as the sequence window feature to feed into the multi-layer BLSTM. So our model does not rely on any other extra domain specific knowledge and complex preprocess, e.g. word segmentation, part of speech tagging and so on. We evaluate AC-BLSTM on sentence-level and document-level tasks including sentiment analysis, question type classification, and subjectivity classification. Experimental results demonstrate the effectiveness of our approach compared with other state-of-the-art methods. Further more, inspired by the ideas of extending GANs to the semi-supervised learning context by BIBREF18 , BIBREF19 , we propose a semi-supervised learning framework for text classification which further improve the performance of AC-BLSTM.\nThe rest of the paper is organized as follows. Section 2 presents a brief review of related work. Section 3 discusses the architecture of our AC-BLSTM and our semi-supervised framework. Section 4 presents the experiments result with comparison analysis. Section 5 concludes the paper.\nIn this paper, We proposed an end-to-end architecture named AC-BLSTM by combining the ACNN with the BLSTM for sentences and documents modeling.",

For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nWe start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text.",

        "question": "Imagine you are part of the city government responsible for urban planning. Write a letter to address the biggest ethical obligation behind a LASER-like system.",
        "evidence": "",
        "answer": "As a division in charge of urban planning for the City of Los Angeles, we are obligated to ensure that the LASER system delivers sustainable and equitable improvements for our neighborhoods, especially the socially marginalized ones. To that end, we need LASER to generate outputs that would not target racial groups – African American communities, for example – and in turn aggravate the pre-existing police harassment in those regions. Yet, there exists no possible source of data inputs for LASER to achieve such goal. The algorithm has been historically accused of racial profiling despite not using race as a predictor for criminal tendencies. However, our society is fraught with deep-rooted racism such that data points themselves bear the mark of discriminatory ideology and practices. For instance, gang membership as a predictor in LASER essentially serves as a proxy for race. Gangs in African American communities arose as a result of economic deprivation, resource insufficiency, as well as police harassment – phenomena with roots that can be  easily traced back to age-old racial segregation. Similarly, criminal records hold the vestiges of the New Jim Crow. Therefore, using gang activity and past arrests as predictors in the LASER system only generate outputs with heavy racial connotations, which in turn reinforce and reify historical biases.\n\nNotwithstanding the problematic algorithm, we do not need to cast away the system entirely. When LASER points to places of deep-rooted discrimination and deprivation, we should mend but not aggravate. Instead of composing chronic offender bulletins, we can treat the LASER outputs as agenda for our next social welfare and infrastructure construction projects – where do we need to build more schools and hospitals? Where should the money go to create more job opportunities? Where do we need to address the problem of police misconduct and rebuild the relationship between people and law enforcement? If we cannot fix a “bias in, bias out” algorithm, we can at least attend to the information it has generated and figure out where the biases have wreaked havoc and taken a heavy toll. We can then redistribute resources and fundings accordingly so that the historically deprived neighborhoods have the chance to flourish. In doing so, we can achieve both sustainability and equity. We can expect the crime rates to go down when the neighborhood achieves economic growth and employment, and such crime reduction is sustainable, unlike the original LASER system that continues to discriminate and deprive.",

        "answer": "As mentioned in [1], which you referenced, similar explanations should be provided for similar inputs. This leads to the stability of the explanation noted in [1]. We conduct additional experiments to demonstrate the stability of our explanation. In a prototype-based method, the explanation changes through a change in distance as the input changes. After distorting the input, we measure the changes in distances.\n\nFor fairness of measurements, the (normalized) distance change is calculated by |\"distance from the prototype obtained from the input\" – \"distance from the prototype obtained from the distorted input\"| / \"distance from the prototype obtained from the input\". We measure these distance changes for each prototype of all inputs. We also used torchvision's RandomPerspective function to distort the input while maintaining a similar shape. The distance change values obtained in this way are as follows.\n\nDistortion FactorVAE - median FactorVAE - avg VAE - median VAE - avg Baseline - median Baseline - avg\n0.1 0.0222 0.0294 0.0293 0.0390 0.0701 0.1580\n0.2 0.0421 0.0535 0.0595 0.0735 0.1535 0.4666\n0.3 0.0502 0.0634 0.0730 0.0923 0.1908 0.6697\n0.4 0.0630 0.0784 0.0907 0.1095 0.2575 1.1177\n0.5 0.0732 0.0921 0.1044 0.1283 0.3224 1.6922\nFrom the above results, it is observed that our model shows much more stable results for input distortions. In particular, in the case of the baseline model, there is a large difference in terms of average and median, which means that there are explanations that provide significantly different distances when the inputs are distorted. This may be because, as we claimed, similar latent representations did not guarantee the similarity of shapes in existing models. Based on our experimental results, it is claimed that the explanation provided by our model is more “stable”. Our explanation shows better stability by providing similar distances for similar inputs, and it will be more reliable.\n\nThe above table will be produced as a plot with the X-axis as distortion, and the Y-axis as mean and median. We will add the above description with a plot to section 4.1.\n\nWe greatly appreciate this particular reviewer’s comment because it was helpful for us to create a new quantitative metric, and to evaluate the quality of explanations.",

        "question": "What was the first vid on YT?",
        "evidence": "YouTube was founded by Steve Chen, Chad Hurley, and Jawed Karim. The trio were early employees of PayPal, which left them enriched after the company was bought by eBay. Hurley had studied design at the Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois Urbana-Champaign.\n\nAccording to a story that has often been repeated in the media, Hurley and Chen developed the idea for YouTube during the early months of 2005, after they had experienced difficulty sharing videos that had been shot at a dinner party at Chen's apartment in San Francisco. Karim did not attend the party and denied that it had occurred, but Chen remarked that the idea that YouTube was founded after a dinner party \"was probably very strengthened by marketing ideas around creating a story that was very digestible\".\n\nKarim said the inspiration for YouTube first came from the Super Bowl XXXVIII halftime show controversy, when Janet Jackson's breast was briefly exposed by Justin Timberlake during the halftime show. Karim could not easily find video clips of the incident and the 2004 Indian Ocean Tsunami online, which led to the idea of a video-sharing site. Hurley and Chen said that the original idea for YouTube was a video version of an online dating service and had been influenced by the website Hot or Not. They created posts on Craigslist asking attractive women to upload videos of themselves to YouTube in exchange for a $100 reward. Difficulty in finding enough dating videos led to a change of plans, with the site's founders deciding to accept uploads of any video.\n\n\nThe YouTube logo used from its launch until 2007; it returned in 2008 before being removed again in 2010. Another version of this logo without the \"Broadcast Yourself\" slogan was used until 2011.\nYouTube began as a venture capital–funded technology startup. Between November 2005 and April 2006, the company raised money from various investors, with Sequoia Capital, $11.5 million, and Artis Capital Management, $8 million, being the largest two. YouTube's early headquarters were situated above a pizzeria and a Japanese restaurant in San Mateo, California. In February 2005, the company activated www.youtube.com. The first video was uploaded April 23, 2005. Titled Me at the zoo, it shows co-founder Jawed Karim at the San Diego Zoo and can still be viewed on the site. In May, the company launched a public beta and by November, a Nike ad featuring Ronaldinho became the first video to reach one million total views. The site launched officially on December 15, 2005, by which time the site was receiving 8 million views a day. Clips at the time were limited to 100 megabytes, as little as 30 seconds of footage.\n\nYouTube was not the first video-sharing site on the Internet; Vimeo was launched in November 2004, though that site remained a side project of its developers from CollegeHumor at the time and did not grow much, either. The week of YouTube's launch, NBC-Universal's Saturday Night Live ran a skit \"Lazy Sunday\" by The Lonely Island. Besides helping to bolster ratings and long-term viewership for Saturday Night Live, \"Lazy Sunday\"'s status as an early viral video helped establish YouTube as an important website. Unofficial uploads of the skit to YouTube drew in more than five million collective views by February 2006 before they were removed when NBCUniversal requested it two months later based on copyright concerns. Despite eventually being taken down, these duplicate uploads of the skit helped popularize YouTube's reach and led to the upload of more third-party content. The site grew rapidly; in July 2006, the company announced that more than 65,000 new videos were being uploaded every day and that the site was receiving 100 million video views per day.\n\nThe choice of the name www.youtube.com led to problems for a similarly named website, www.utube.com. That site's owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube subsequently changed its website to www.utubeonline.com.",

You’ll want to remove steaks from the refrigerator 20 minutes before grilling and let sit, covered, at room temperature. During this time, preheat your grill on high. \n\nAfter 20 minutes, you’ll want to brush the steaks on both sides with oil and season liberally with salt and pepper, or your desired steak seasoning. \n\nOnce the steaks and grill are both ready, you’ll place the steaks on the grill and cook until golden brown and slightly charred, which should take roughly 4 to 5 minutes. Turn the steaks and continue to grill for an additional 4 – 5 minutes for medium-rare, which has an internal temperature of 135 degrees Fahrenheit. For medium, you’ll grill for 5 to 7 minutes or 140 degrees Fahrenheit, or 8 to 10 minutes for medium-well at 150 degrees Fahrenheit. \n\nAt the desired steak temperature, you will remove and transfer the steaks to a cutting board or platter, and let rest for 5 minutes before slicing and serving.",

Higher upfront cost: Electric cars are generally more expensive to acquire than gasoline-powered cars, although this gap is narrowing. But, electric vehicles are typically cheaper to run and maintain. At this stage, they have achieved parity for the total cost of ownership.\n2. Increased charging times: New electric cars can get to 80% of their range in less than half an hour when using fast charging stations, but that still slower than their combustion engine counterparts and many charging stations have lower speeds.\n3. Limited charging infrastructure: Despite the expansion of electric vehicle charging facilities, their availability remains less extensive than that of gas stations. Consequently, careful trip planning may be necessary to guarantee access to charging stations when required.\n4. Less range: New electric cars typically have a range of around 230-320 miles, which is still less than most of the combustion engine vehicles.\n5.

        "evidence": "In contrast to 2018, when we submitted BIBREF2 to BioASQ a system based on extractive summarization (and scored very high in the ideal answer category), this year we mainly targeted factoid question answering task and focused on experimenting with BioBERT. After these experiments we see the promise of BioBERT in QA tasks, but we also see its limitations. The latter we tried to address with mixed results using feature engineering. Overall these experiments allowed us to secure a best and a second best score in different test batches. Along with Factoid-type question, we also tried ‘Yes/No’ and ‘List’-type questions, and did reasonably well with our very simple approach.\nFor Yes/No the moral worth remembering is that reasoning has a potential to influence results, as evidenced by our adding the AllenNLP entailment BIBREF13 system increased its performance.\nAll our data and software is available at Github, in the previously referenced URL (end of Section 2).\nIn the current model, we have a shallow neural network with a softmax layer for predicting answer span. Shallow networks however are not good at generalizations. In our future experiments we would like to create dense question answering neural network with a softmax layer for predicting answer span. The main idea is to get contextual word embedding for the words present in the question and paragraph (Context) and feed the contextual word embeddings retrieved from the last layer of BioBERT to the dense question answering network. The mentioned dense layered question answering neural network need to be tuned for finding right hyper parameters. An example of such architecture is shown in Fig.FIGREF30.\nIn one more experiment, we would like to add a better version of ‘LAT’ contextual word embedding as a feature, along with the actual contextual word embeddings for question text, and Context and feed them as input to the dense question answering neural network. By this experiment, we would like to find if ‘LAT’ feature is improving overall answer prediction accuracy. Adding ‘LAT’ feature this way instead of feeding this word piece embedding directly to the BioBERT (as we did in our above experiments) would not downgrade the quality of contextual word embeddings generated form ‘BioBERT'. Quality contextual word embeddings would lead to efficient transfer learning and chances are that it would improve the model's answer prediction accuracy.\nWe also see potential for incorporating domain specific inference into the task e.g. using the MedNLI dataset BIBREF14. For all types of experiments it might be worth exploring clinical BERT embeddings BIBREF15, explicitly incorporating domain knowledge (e.g. BIBREF16) and possibly deeper discourse representations (e.g. BIBREF17).\nIn the current model, we have a shallow neural network with a softmax layer for predicting answer span.

In this experiment we would neglect all embeddings for the question text except that of Focus word/ ‘LAT’. Our assumption and idea for considering focus word and neglecting remaining words in the question is that during training phase it would make more precise for the model to identify the focus of the question and map answers against the question’s focus. To validate our assumption, we would like to take sample question answering data and find the cosine distance between contextual embedding of Focus word and that of the actual answer and verify if the cosine distance is comparatively low in most of the cases.\nIn one more experiment, we would like to add a better version of ‘LAT’ contextual word embedding as a feature, along with the actual contextual word embeddings for question text, and Context and feed them as input to the dense question answering neural network. By this experiment, we would like to find if ‘LAT’ feature is improving overall answer prediction accuracy. Adding ‘LAT’ feature this way instead of feeding Focus word’s word piece embedding directly (as we did in our above experiments) to the BioBERT would not downgrade the quality of contextual word embeddings generated form ‘BioBERT'. Quality contextual word embeddings would lead to efficient transfer learning and chances are that it would improve the model's answer prediction accuracy.\nIn contrast to 2018, when we submitted BIBREF2 to BioASQ a system based on extractive summarization (and scored very high in the ideal answer category), this year we mainly targeted factoid question answering task and focused on experimenting with BioBERT. After these experiments we see the promise of BioBERT in QA tasks, but we also see its limitations. The latter we tried to address with mixed results using feature engineering. Overall these experiments allowed us to secure a best and a second best score in different test batches. Along with Factoid-type question, we also tried ‘Yes/No’ and ‘List’-type questions, and did reasonably well with our very simple approach.\nFor Yes/No the moral worth remembering is that reasoning has a potential to influence results, as evidenced by our adding the AllenNLP entailment BIBREF13 system increased its performance.\nAll our data and software is available at Github, in the previously referenced URL (end of Section 2).\nIn the current model, we have a shallow neural network with a softmax layer for predicting answer span. Shallow networks however are not good at generalizations. In our future experiments we would like to create dense question answering neural network with a softmax layer for predicting answer span. The main idea is to get contextual word embedding for the words present in the question and paragraph (Context) and feed the contextual word embeddings retrieved from the last layer of BioBERT to the dense question answering network. The mentioned dense layered question answering neural network need to be tuned for finding right hyper parameters. An example of such architecture is shown in Fig.FIGREF30.\nIn one more experiment, we would like to add a better version of ‘LAT’ contextual word embedding as a feature, along with the actual contextual word embeddings for question text, and Context and feed them as input to the dense question answering neural network.

Pigeons are the most often seen animals in Cologne, although the number of birds is augmented each year by a growing population of feral exotics, most visibly parrots such as the rose-ringed parakeet. The sheltered climate in southeast Northrhine-Westphalia allows these birds to survive through the winter, and in some cases, they are displacing native species. The plumage of Cologne's green parrots is highly visible even from a distance, and contrasts starkly with the otherwise muted colours of the cityscape.",
        "answer": "Although, the passage about the wildlife in the city of Cologne does not mention cats, it is possible to encounter cats in Cologne since it is very common for people in western cultures to own cats and let them outside on their own. The reason cats are not mentioned in the passage is that cats are not considered wildlife but pets.

        "evidence": "Automatic Text Summarization deals with the task of condensing documents into a summary, whose level is similar to a human-generated summary. It is mostly distributed into two distinct domains, i.e., Abstractive Summarization and Extractive Summarization. Abstractive summarization( Dejong et al. ,1978) involves models to deduce the crux of the document. It then presents a summary consisting of words and phrases that were not there in the actual document, sometimes even paraphrasing BIBREF1 . A state of art method proposed by Wenyuan Zeng BIBREF2 produces such summaries with length restricted to 75. There have been many recent developments that produce optimal results, but it is still in a developing phase. It highly relies on natural language processing techniques, which is still evolving to match human standards. These shortcomings make abstractive summarization highly domain selective. As a result, their application is skewed to the areas where NLP techniques have been superlative. Extractive Summarization, on the other hand, uses different methods to identify the most informative/dominant sentences through the text, and then present the results, ranking them accordingly. In this paper, we have proposed two novel stand-alone summarization methods.The first method is based on Glove Model BIBREF3 ,and other is based on Facebook's InferSent BIBREF4 . We have also discussed how we can effectively subdue shortcomings of one model by using it in coalition with models which capture the view that other faintly held.\nIt is the first to explore the potential of utilizing intermediate layers of BERT and we design two effective information pooling strategies to solve aspect based sentiment analysis task.",

        "answer": "Three.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set.",

Note that the translators had access to the transcripts but not the corresponding voice clips since clips would not carry additional information.

These event categories are chosen as they are representative of important event types that are of interest to many governments and companies. The need to create our own dataset was motivated by the lack of public datasets for event detection on microposts. The few available datasets do not suit our requirements. For example, the publicly available Events-2012 Twitter dataset BIBREF20 contains generic event descriptions such as Politics, Sports, Culture etc. Our work targets more specific event categories BIBREF21. Following previous studies BIBREF1, we collect event-related microposts from Twitter using 11 and 8 seed events (see Section SECREF2) for CyberAttack and PoliticianDeath, respectively. Unlabeled microposts are collected by using the keyword `hack' for CyberAttack, while for PoliticianDeath, we use a set of keywords related to `politician' and `death' (such as `bureaucrat', `dead' etc.) For each dataset, we randomly select 500 tweets from the unlabeled subset and manually label them for evaluation. Table TABREF25 shows key statistics from our two datasets.\nComparison Methods. To demonstrate the generality of our approach on different event detection models, we consider Logistic Regression (LR) BIBREF1 and Multilayer Perceptron (MLP) BIBREF2 as the target models.

Also, we note that in our case other neural network models with more complex network architectures for event detection, such as the bi-directional LSTM BIBREF17, turn out to be less effective than a simple feedforward network. For both LR and MLP, we evaluate our proposed human-AI loop approach for keyword discovery and expectation estimation by comparing against the weakly supervised learning method proposed by BIBREF1 (BIBREF1) and BIBREF17 (BIBREF17) where only one initial keyword is used with an expectation estimated by an individual expert.\nParameter Settings. We empirically set optimal parameters based on a held-out validation set that contains 20% of the test data. These include the hyperparamters of the target model, those of our proposed probabilistic model, and the parameters used for training the target model. We explore MLP with 1, 2 and 3 hidden layers and apply a grid search in 32, 64, 128, 256, 512 for the dimension of the embeddings and that of the hidden layers. For the coefficient of expectation regularization, we follow BIBREF6 (BIBREF6) and set it to $\\lambda =10 \\times $ #labeled examples. For model training, we use the Adam BIBREF22 optimization algorithm for both models.\nEvaluation. Following BIBREF1 (BIBREF1) and BIBREF3 (BIBREF3), we use accuracy and area under the precision-recall curve (AUC) metrics to measure the performance of our proposed approach. We note that due to the imbalance in our datasets (20% positive microposts in CyberAttack and 27% in PoliticianDeath), accuracy is dominated by negative examples; AUC, in comparison, better characterizes the discriminative power of the model.\nCrowdsourcing. We chose Level 3 workers on the Figure-Eight crowdsourcing platform for our experiments. The inter-annotator agreement in micropost classification is taken into account through the EM algorithm. For keyword discovery, we filter keywords based on the frequency of the keyword being selected by the crowd. In terms of cost-effectiveness, our approach is motivated from the fact that crowdsourced data annotation can be expensive, and is thus designed with minimal crowd involvement. For each iteration, we selected 50 tweets for keyword discovery and 50 tweets for micropost classification per keyword. For a dataset with 80k tweets (e.g., CyberAttack), our approach only requires to manually inspect 800 tweets (for 8 keywords), which is only 1% of the entire dataset.\nWe perform our experiments with two predetermined event categories: cyber security (CyberAttack) and death of politicians (PoliticianDeath).",

Oneida Indian Nation of New York (2005).\n\nGinsburg was born and grew up in Brooklyn, New York. Her older sister died when she was a baby, and her mother died shortly before Ginsburg graduated from high school. She earned her bachelor's degree at Cornell University and married Martin D. Ginsburg, becoming a mother before starting law school at Harvard, where she was one of the few women in her class. Ginsburg transferred to Columbia Law School, where she graduated joint first in her class. During the early 1960s she worked with the Columbia Law School Project on International Procedure, learned Swedish, and co-authored a book with Swedish jurist Anders Bruzelius; her work in Sweden profoundly influenced her thinking on gender equality. She then became a professor at Rutgers Law School and Columbia Law School, teaching civil procedure as one of the few women in her field.\n\nGinsburg spent much of her legal career as an advocate for gender equality and women's rights, winning many arguments before the Supreme Court. She advocated as a volunteer attorney for the American Civil Liberties Union and was a member of its board of directors and one of its general counsel in the 1970s. In 1980, President Jimmy Carter appointed her to the U.S. Court of Appeals for the District of Columbia Circuit, where she served until her appointment to the Supreme Court in 1993. Between O'Connor's retirement in 2006 and the appointment of Sonia Sotomayor in 2009, she was the only female justice on the Supreme Court. During that time, Ginsburg became more forceful with her dissents, such as with Ledbetter v. Goodyear Tire & Rubber Co. (2007). Ginsburg's dissenting opinion was credited with inspiring the Lilly Ledbetter Fair Pay Act which was signed into law by President Barack Obama in 2009, making it easier for employees to win pay discrimination claims. Ginsburg received attention in American popular culture for her passionate dissents in numerous cases, widely seen as reflecting paradigmatically liberal views of the law. She was dubbed \"The Notorious R.B.G.\", and she later embraced the moniker.\n\nDespite two bouts with cancer and public pleas from liberal law scholars, she decided not to retire in 2013 or 2014 when Obama and a Democratic-controlled Senate could appoint and confirm her successor. Ginsburg died at her home in Washington, D.C., on September 18, 2020, at the age of 87, from complications of metastatic pancreatic cancer. The vacancy created by her death was filled 39 days later by Amy Coney Barrett, a conservative. The result was one of three major rightward shifts in the Court since 1953, following the appointment of Clarence Thomas to replace Thurgood Marshall in 1991 and the appointment of Warren Burger to replace Earl Warren in 1969.",

        "evidence": "The proliferation of the online social media has lately resulted in the democratization of online content sharing. Among other media, Twitter is very popular for research and application purposes due to its scale, representativeness and ease of public access to its content. However, tweets, that are short messages of up to 140 characters, pose several challenges to traditional Natural Language Processing (NLP) systems due to the creative use of characters and punctuation symbols, abbreviations ans slung language.\nNamed Entity Recognition (NER) is a fundamental step for most of the information extraction pipelines. Importantly, the terse and difficult text style of tweets presents serious challenges to NER systems, which are usually trained using more formal text sources such as newswire articles or Wikipedia entries that follow particular morpho-syntactic rules. As a result, off-the-self tools trained on such data perform poorly BIBREF0 . The problem becomes more intense as the number of entities to be identified increases, moving from the traditional setting of very few entities (persons, organization, time, location) to problems with more. Furthermore, most of the resources (e.g., software tools) and benchmarks for NER are for text written in English. As the multilingual content online increases, and English may not be anymore the lingua franca of the Web. Therefore, having resources and benchmarks in other languages is crucial for enabling information access worldwide.\nIn this paper, we propose a new benchmark for the problem of NER for tweets written in French. The tweets were collected using the publicly available Twitter API and annotated with 13 types of entities. The annotators were native speakers of French and had previous experience in the task of NER. Overall, the generated datasets consists of INLINEFORM0 tweets, split in training and test parts.\nThe paper is organized in two parts. In the first, we discuss the data preparation steps (collection, annotation) and we describe the proposed dataset. The dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated. Following, the second part of the paper presents an overview of baseline systems and the approaches employed by the systems that participated. We conclude with a discussion of the performance of Twitter NER systems and remarks for future work.\nThe dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated.",

        "evidence": "Gradient descent-based methods BIBREF20, BIBREF21, BIBREF22, BIBREF23 are popularly used in optimizing deep neural networks. For convolutional neural networks and recurrent neural networks, a relatively large learning rate is usually set in the beginning, and then decreased along with the optimization process BIBREF24, BIBREF25, BIBREF26, BIBREF27, BIBREF28. The learning rate warm-up stage has only been shown essential in dealing with some very specific problems, e.g., the large-batch training. BIBREF29, BIBREF28, BIBREF30 showed that a learning rate warm-up stage is preferred when training neural networks with extremely large batch sizes.\nHowever, the learning rate warm-up stage is essential and critical when optimizing the Transformer models in a majority of scenarios BIBREF0, BIBREF8, BIBREF3, BIBREF7, BIBREF31. BIBREF10 investigated the influence of different warm-up strategies for the optimization of the Post-LN Transformer model and found that without or with relatively less warm-up iterations, the optimization diverges. The Pre-LN Transformer has been proposed in several recent works BIBREF18, BIBREF19, BIBREF2 to alleviate some optimization issues when training deeper models, but the troublesome warm-up stage still remains in their training pipelines.\nIn a concurrent and independent work BIBREF11, the authors claimed that the benefit of the warm-up stage comes from reducing the variance for the adaptive learning rate in the Adam optimizer BIBREF20. They proposed to rectify the variance of adaptive learning rate by a new variant of Adam called RAdam. However, we find that not only for Adam, the learning rate warm-up stage also helps quite a lot for other optimizers. This may indicate that Adam is not the prerequisite for the necessity of the warm-up stage. Therefore, we re-identify the problem and find that it highly relates to the architecture, in particular, the position of layer normalization.\nDespite its great success, people usually need to deal with the optimization of the Post-LN Transformer more carefully than convolutional networks or other sequence-to-sequence models (Popel & Bojar, 2018). In particular, to train the model from scratch, any gradient-based optimization approach requires a learning rate warm-up stage (Vaswani et al., 2017; Liu et al., 2019a): the optimization starts with an extremely small learning rate, and then gradually increases it to a pre-defined maximum value in a pre-defined number of iterations. Such a warm-up stage not only slows down the optimization process but also brings more hyperparameter tunings. Popel & Bojar (2018) has shown that the final model performance is quite sensitive to the value of the maximum learning rate and the number of warm-up iterations. Tuning such sensitive hyper-parameters is costly in training large-scale models, e.g., BERT (Devlin et al., 2018) or XLNet (Yang et al., 2019b). In this paper, we try to alleviate this problem by finding ways to safely remove the learning rate warm-up stage.",

Twitter activity consists of short posts called tweets which are limited to 140 characters. Retweets, where users repost a tweet to spread its content, were not considered. (The spread of causal statements will be considered in future work.) We considered only English-language tweets for this study. To avoid cross-language effects, we kept only tweets with a user-reported language of `English' and, as a second constraint, individual tweets needed to match more English stopwords than any other language's set of stopwords. Stopwords considered for each language were determined using NLTK's database BIBREF29 . A tweet will be referred to as a `document' for the rest of this work.\nCausal documents were chosen to contain one occurrence only of the exact unigrams: `caused', `causing', or `causes'. The word `cause' was not included due to its use as a popular contraction for `because'. One `cause-word' per document restricted the analysis to single relationships between two relata. Documents that contain bidirectional words (`associate', `relate', `connect', `correlate', and any of their stems) were also not selected for analysis. This is because our focus is on causality, an inherently one-sided relationship between two objects. We also did not consider additional synonyms of these cause words, although that could be pursued for future work. Control documents were also selected. These documents did not contain any of `caused', `causing', or `causes', nor any bidirectional words, and are further matched temporally to obtain the same number of control documents as causal documents in each fifteen-minute period during 2013. Control documents were otherwise selected randomly; causal synonyms may be present. The end result of this procedure identified 965,560 causal and 965,560 control documents.

Scott released his own version of his song on his 1997 album Aloha from Nashville.\n\nThe song was also recorded by The Sky Kings, an American country-rock supergroup consisting of Bill Lloyd (Foster & Lloyd), Rusty Young (Poco), and John Cowan (New Grass Revival) around 1995/1996. Their version sat unreleased until Rhino Handmade released the compilation \"From Out Of The Blue\" in 2000.\n\nThe song was later covered more famously by American country music artist Travis Tritt. It was released in December 2000 as the second single from his album Down the Road I Go. It peaked at number 2 on the U.S. Billboard Hot Country Singles & Tracks chart and at number 33 on the U.S. Billboard Hot 100 chart.\n\nIt was subsequently covered by Pat Green and Cory Morrow on their March 2001 album Songs We Wish We'd Written and by Niko Moon for his 2021 album Good Time.",

Therefore, we think that there is a room for improvements which can be achieved by interactively asking for additional information in conversational dialogs with users. This extra information can be used for improving policies of dialog systems. We call this approach the interactive learning from dialogs.\nWe can improve dialog systems in several aspects through interactive learning in a direct interaction with users. First, the most straightforward way obviously is getting the correct answer for questions that the system does not know. We can try to ask users for answers on questions that the system encountered in a conversation with a different user and did not understand it. Second, the system can ask the user for a broader explanation of a question. This explanation could help the system to understand the question and provide the correct answer. In addition, the system can learn correct policy for the question which allows providing answers without asking any extra information for similar questions next time. We hypothesize that users are willing to give such explanations because it could help them to find answers for their own questions.

        "question": "Based on the following passage what is alternating current affected by?",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

Moore's law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel (and former CEO of the latter), who in 1965 posited a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 41%. While Moore did not use empirical evidence in forecasting that the historical trend would continue, his prediction held since 1975 and has since become known as a \"law\". Moore's prediction has been used in the semiconductor industry to guide long-term planning and to set targets for research and development, thus functioning to some extent as a self-fulfilling prophecy. Advancements in digital electronics, such as the reduction in quality-adjusted microprocessor prices, the increase in memory capacity (RAM and flash), the improvement of sensors, and even the number and size of pixels in digital cameras, are strongly linked to Moore's law. These ongoing changes in digital electronics have been a driving force of technological and social change, productivity, and economic growth. Industry experts have not reached a consensus on exactly when Moore's law will cease to apply. Microprocessor architects report that semiconductor advancement has slowed industry-wide since around 2010, slightly below the pace predicted by Moore's law. In September 2022 Nvidia CEO Jensen Huang considered Moore's law dead, while Intel CEO Pat Gelsinger was of the opposite view.",

        "question": "Does the SVAE significantly improve the NMI and the precision?",
        "answer": "Yes, it does.",
        "evidence": "First, we evaluated the standard HMM model with an uninformative prior (this will be our baseline) for the two different input features: MFCC (and derivatives) and MBN. Results are shown in Table TABREF20 . Surprisingly, the MBN features perform relatively poorly compared to the standard MFCC. These results are contradictory to those reported in BIBREF3 . Two factors may explain this discrepancy: the Mboshi5k data being different from the training data of the MBN neural network, the neural network may not generalize well. Another possibility may be that the initialization scheme of the model is not suitable for this type of features. Indeed, Variational Bayesian Inference algorithm converges only to a local optimum of the objective function and is therefore dependent of the initialization. We believe the second explanation is the more likely since, as we shall see shortly, the best results in term of word segmentation and NMI are eventually obtained with the MBN features when the inference is done with the informative prior. Next, we compared the HMM and the SVAE models when trained with an uninformative prior (lines with \"Inf. Prior\" set to \"no\" in Table TABREF23 ). The SVAE significantly improves the NMI and the precision showing that it extracts more consistent units than the HMM model. However, it also degrades the segmentation in terms of recall. We further investigated this behavior by looking at the duration of the units found by both models compared to the true phones (Table TABREF22 ). We observe that the SVAE model favors longer units than the HMM model hence leading to fewer boundaries and consequently smaller recall.\nWe then evaluated the effect of the informative prior on the acoustic unit discovery (Table TABREF23 ). On all 4 combinations (2 features sets INLINEFORM0 2 models) we observe an improvement in terms of precision and NMI but a degradation of the recall. This result is encouraging since the informative prior was trained on English data (TIMIT) which is very different from Mboshi. Indeed, this suggests that even speech from an unrelated language can be of some help in the design of an ASR for a very low resource language. Finally, similarly to the SVAE/HMM case described above, we found that the degradation of the recall is due to longer units discovered for models with an informative prior (numbers omitted due to lack of space).\nWord discovery results are given in Table TABREF21 for the Boundary metric BIBREF20 , BIBREF21 . We observe that i) the best word boundary detection (F-score) is obtained with MBN features, an informative prior and the SVAE model; this confirms the results of table TABREF23 and shows that better AUD leads to better word segmentation ii) word segmentation from AUD graph Lattices is slightly better than from flat sequences of AUD symbols (1-best); iii) our results outperform a pure speech based baseline based on segmental DTW BIBREF22 (F-score of 19.3% on the exact same corpus).\nThe SVAE significantly improves the NMI and the precision showing that it extracts more consistent units than the HMM model.",

Banks with high credit ratings (Aa/AA or above) borrow money from each other at the LIBOR rates. These yield curves are typically a little higher than government curves.

        "answer": "Yes.",
        "evidence": "In the first experiment the model was trained using pretrained vectors extracted from two different sources, Common Crawl and Wikipedia and can be found at the official FastText web page BIBREF8. Both sources were trained on the same algorithm called FastText BIBREF9, an extension of Word2Vec that treats tokens as an average sum of sub-words and finds similarities of words based on their n-grams. The configuration of the FastText model for Wikipedia vectors is according to BIBREF10, whilst the model for CC vectors is a position-weight CBOW 5 length n-grams with a window size of 5 tokens and 10 negative words. The file with the Common Crawl vectors consists of 2.000.000 tokens with 300 dimension, whereas the file with the Wikipedia vectors consists of 300.000 tokens with 300 dimension.The results can be viewed in the following table, with the first part describing the Common Crawl results and the second one the Wikipedia results.\nAt the results, POS and morph classes refer to the tag labels explained in SECREF4, whilst only POS classes relate to annotated labels that describe only the part of speech. It is evident that even though the CC vectors are noisy, coming from a web source, they lead to better results than Wikipedia, possibly because they have a larger variety of tokens.\nIn the next experiment, the dataset was used for the composition of embeddings for the part of speech tagger. The dataset was trained on a FastText model with the same parameters that extracted the Common Crawl vectors. As a result, 140.000 vectors with 300 dimension were exported. It must be mentioned that the tagset with the morphological features was used.\nThe values of the metrics in this case were almost as good and comparable to the CC ones. However, the model trained with a larger vocabulary had higher results. Also, the model with the dataset vectors did not have the flexibility to classify unknown words.\nAs a next step, the test set of the dataset was altered by replacing words with syntactical mistakes to test the tolerance of the model in OOV words. Suffixes of verbs were altered and vowels were replaced with others, affecting 20% of the tokens of the dataset. Using again the more complex tagset for training, the results can be found in Table 3.\nWhat can be concluded is that the model did not have a flexibility in OOV words. Of course, this can also be an advantage, meaning that the model recognized the mismatch of a wrong word with its class.\nOne disadvantage that the previous model had is that for unknown words the model assigned a zero vector, affecting the testing results. In order to minimize this problem, the unknown words were first passed through a FastText model to get a vector from their subwords. The resulting vectors were imported in the vocabulary with the CC vectors before training. The model was also trained using as a vocabulary the unknown words and the tokens from the Common Crawl vectors, both buffered in the same FastText model. Results are listed in Table 4.\nIt was noticed that the model performed better when using the vectors from different FastText models. It was expected that the second experiment would have performed better, as the tokens were inserted into the same FastText model and the vectors exported from both sources should match.\nBoth datasets were fed into the library in proper format for training. In training process, the entity recognizer had the same configuration with the POS tagger, using the same percentages for train, validation and test sets. It must be noted that all the models used the Common Crawl pretrained vectors for a vocabulary. The results are compared using the macro F1 score.\nAt first the datasets from both sources (Makedonia, Wikipedia) were used for training with 10 iterations and testing from the model. The results can be viewed in the following table:\nIt seemed that the average F1 score was higher for the Makedonia corpus, as it was the basis of the configuration for the keyword list. In order to have an objective evaluation, the results of each corpus per entity class were observed.\nBoth sources had good results in non entity tokens, which affected the F1 score. Moreover, the model did not perform well for facilities, as polyglot's Greek recognizer does not support that class and FAC entities cover a small amount of the list.\nIn the second experiment, the datasets were compared to a common test set that followed the desired set of rules.\nAgain, the Makedonia corpus performed better, because of the proper annotation on the keyword list.\nIn an experiment worth mentioning the correlation of the part of speech with the performance of the recognizer was explored. In this experiment, both pipelines (part of speech, entity recognition) were used for training with 30 iterations and the model was trained twice: with and without the usage of the part of speech information for recognition.\nIt is evident that the recognizer did not gain knowledge from the part of speech tags of the tokens.\nIn training process, the entity recognizer had the same configuration with the POS tagger, using the same percentages for train, validation and test sets.",

        "evidence": "Words with multiple senses commonly exist in many languages. For example, the word bank can either mean a “financial establishment” or “the land alongside or sloping down to a river or lake”, based on different contexts. Such a word is called a “polyseme”. The task to identify the meaning of a polyseme in its surrounding context is called word sense disambiguation (WSD). Word sense disambiguation is a long-standing problem in natural language processing (NLP), and has broad applications in other NLP problems such as machine translation BIBREF0 . Lexical sample task and all-word task are the two main branches of WSD problem. The former focuses on only a pre-selected set of polysemes whereas the later intends to disambiguate every polyseme in the entire text. Numerous works have been devoted in WSD task, including supervised, unsupervised, semi-supervised and knowledge based learning BIBREF1 . Our work focuses on using supervised learning to solve all-word WSD problem.\nMost supervised approaches focus on extracting features from words in the context. Early approaches mostly depend on hand-crafted features. For example, IMS by BIBREF2 uses POS tags, surrounding words and collections of local words as features. These approaches are later improved by combining with word embedding features BIBREF0 , which better represents the words' semantic information in a real-value space. However, these methods neglect the valuable positional information between the words in the sequence BIBREF3 . The bi-directional Long-Short-Term-Memory (LSTM) approach by BIBREF3 provides one way to leverage the order of words. Recently, BIBREF4 improved the performance by pre-training a LSTM language model with a large unlabelled corpus, and using this model to generate sense vectors for further WSD predictions. However, LSTM significantly increases the computational complexity during the training process.\nThe development of the so called “fixed-size ordinally forgetting encoding” (FOFE) has enabled us to consider more efficient method. As firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence. FOFE has been applied to several NLP problems in the past, such as language model BIBREF5 , named entity recognition BIBREF6 , and word embedding BIBREF7 . The promising results demonstrated by the FOFE approach in these areas inspired us to apply FOFE in solving the WSD problem. In this paper, we will first describe how FOFE is used to encode sequence of any length into a fixed-size representation. Next, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data. Lastly, we provide the experiment results of our method on several WSD data sets to justify the equivalent performance as the state-of-the-art approach.\nTo demonstrate the applicability of our approach, we apply topic modelling to msmarco — a comprehension data set based on internet search queries — and collect examples that belong to a number of salient topics, producing 6 small to medium sized RC data sets for the following domains: biomedical, computing, film, finance, law and music.",

In this section, we first describe our problem setup and key terminologies by discussing the dataset used. Later, we formalize our problem definition.\nDataset: For our explorations, we use the Craigslist Bargaining dataset (CB) introduced by BIBREF4. Instead of focusing on the previously studied game environments BIBREF5, BIBREF6, the dataset considers a more realistic setup: negotiating the price of products listed on Craigslist. The dataset consists of 6682 dialogues between a buyer and a seller who converse in natural language to negotiate the price of a given product (sample in Table TABREF1). In total, 1402 product ad postings were scraped from Craigslist, belonging to six categories: phones, bikes, housing, furniture, car and electronics. Each ad posting contains details such as Product Title, Category Type and a Listing Price. Moreover, a secret target price is also pre-decided for the buyer. The final price after the agreement is called the Agreed Price, which we aim to predict.\nDefining the problem: Say we are provided with a product scenario $S$, a tuple: (Category, Title, Listing Price, Target Price). Define the interactions between a buyer and seller using a sequence of $n$ events $E_n:<e_{1}, e_{2}, ..., e_{n}>$, where $e_{i}$ occurs before $e_{j}$ iff $i<j$. Event $e_{i}$ is also a tuple: (Initiator, Type, Data). Initiator is either the Buyer or Seller, Type can be one of (message, offer, accept, reject or quit) and Data consists of either the corresponding natural language dialogue, offer price or can be empty. Nearly $80\\%$ of events in CB dataset are of type `message', each consisting a textual message as Data. An offer is usually made and accepted at the end of each negotiation. Since the offers directly contain the agreed price (which we want to predict), we only consider `message' events in our models. Given the scenario $S$ and first $n$ events $E_n$, our problem is then to learn the function $f_{n}$: $A = f_{n}(S, E_n)$ where $A$ refers to the final agreed price between the two negotiating parties.\n\nWe use the Craigslist Bargaining dataset (CB) introduced by He et al.

While most observations about the universe leave the question unanswered the broad strokes are as follows.\n\nTheologians state in many religions that there is an organizing force known as God providing direction to the universe.  Humans that best align with this organizing force or God are guaranteed good fortune in this life or after.  There are variations in humans level of involvement in this process with Christianity requiring a savior (Jesus) for people to enter the afterlife vs achieving a higher state of consciousness in this life or through reincarnation.\n\nPhilosophers differ on the meaning of life with predominate views following down the lines of seeking your own fulfillment or the fulfillment of others.  Seeking your own fulfillment has been a major component of capitalism, self-preservation, and risk taking that lead to new discoveries in Science and Technology.  Seeking the fulfillment of others has lead to great advancements in philanthropy, equality, and the general well being of society.  This \"social compact\" insures stability and provides an expectation that harmful activities like Murder, Robbery, etc are discouraged and punished.\n\nScientists view this question through the lens of the observable universe.  As such efforts have been made to create a \"unifying theory of everything\" to show some understandable order to the universe.  Others have focused their study on the improbability of how humans could have been created in a universe with seemingly random and infinite chance.  Some scientists have conceded that the question is something Science is ill-fitted to answer.\n\nMost importantly Douglas Adams, a prominent British author specializing in absurdity, answered the question in the book \"The Hitchhikers Guide to the Galaxy\" with the answer \"42.\"",

        "evidence": "Given the annotated tweets, we wanted to ascertain the distribution of: types of offensive language, genres where it is used, the dialects used, and the gender of users using such language.\nFigure FIGREF13 shows the distribution of topics associated with offensive tweets. As the figure shows, sports and politics are most dominant for offensive language including vulgar and hate speech. As for dialect, we looked at MSA and four major dialects, namely Egyptian (EGY), Leventine (LEV), Maghrebi (MGR), and Gulf (GLF). Figure FIGREF14 shows that 71% of vulgar tweets were written in EGY followed by GLF, which accounted for 13% of vulgar tweets. MSA was not used in any of the vulgar tweets. As for offensive tweets in general, EGY and GLF were used in 36% and 35% of the offensive tweets respectively. Unlike the case of vulgar language where MSA was non-existent, 15% of the offensive tweets were in fact written in MSA. For hate speech, GLF and EGY were again dominant and MSA consistuted 21% of the tweets. This is consistent with findings for other languages such as English and Italian where vulgar language was more frequently associated with colloquial language BIBREF24, BIBREF25. Regarding the gender, Figure FIGREF15 shows that the vast majority of offensive tweets, including vulgar and hate speech, were authored by males. Female Twitter users accounted for 14% of offensive tweets in general and 6% and 9% of vulgar and hate speech respectively. Figure FIGREF16 shows a detailed categorization of hate speech types, where the top three include insulting groups based on their political ideology, origin, and sport affiliation. Religious hate speech appeared in only 15% of all hate speech tweets.\nNext, we analyzed all tweets labeled as offensive to better understand how Arabic speakers use offensive language. Here is a breakdown of usage:\nDirect name calling: The most frequent attack is to call a person an animal name, and the most used animals were كلب> (“klb” – “dog”), حمار> (“HmAr” – “donkey”), and بهيم> (“bhym” – “beast”). The second most common was insulting mental abilities using words such as غبي> (“gby” – “stupid”) and عبيط> (“EbyT” –“idiot”). Some culture-specific differences should be considered. Not all animal names are used as insults. For example, animals such as أسد> (“Asd” – “lion”), صقر> (“Sqr” – “falcon”), and غزال> (“gzAl” – “gazelle”) are typically used for praise. For other insults, people use: some bird names such as دجاجة> (“djAjp” – “chicken”), بومة> (“bwmp” – “owl”), and غراب> (“grAb” – “crow”); insects such as ذبابة> (“*bAbp” – “fly”), صرصور> (“SrSwr” – “cockroach”), and حشرة> (“H$rp” – “insect”); microorganisms such as جرثومة> (“jrvwmp” – “microbe”) and طحالب> (“THAlb” – “algae”); inanimate objects such as جزمة> (“jzmp” – “shoes”) and سطل> (“sTl” – “bucket”) among other usages.\nSimile and metaphor: Users use simile and metaphor were they would compare a person to: an animal as in زي الثور> (“zy Alvwr” – “like a bull”), سمعني نهيقك> (“smEny nhyqk” – “let me hear your braying”), and هز ديلك> (“hz dylk” – “wag your tail”); a person with mental or physical disability such as منغولي> (“mngwly” – “Mongolian (down-syndrome)”), معوق> (“mEwq” – “disabled”), and قزم> (“qzm” – “dwarf”); and to the opposite gender such as جيش نوال> (“jy$ nwAl” – “Nawal's army (Nawal is female name)”) and نادي زيزي> (“nAdy zyzy” – “Zizi's club (Zizi is a female pet name)”).\nIndirect speech: This type of offensive language includes: sarcasm such as أذكى إخواتك> (“A*kY AxwAtk” – “smartest one of your siblings”) and فيلسوف الحمير> (“fylswf AlHmyr” – “the donkeys' philosopher”); questions such as ايه كل الغباء ده> (“Ayh kl AlgbA dh” – “what is all this stupidity”); and indirect speech such as النقاش مع البهايم غير مثمر> (“AlnqA$ mE AlbhAym gyr mvmr” – “no use talking to cattle”).\nWishing Evil: This entails wishing death or major harm to befall someone such as ربنا ياخدك> (“rbnA yAxdk” – “May God take (kill) you”), الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”), and روح في داهية> (“rwH fy dAhyp” – equivalent to “go to hell”).\nName alteration: One common way to insult others is to change a letter or two in their names to produce new offensive words that rhyme with the original names. Some examples of such include changing الجزيرة> (“Aljzyrp” – “Aljazeera (channel)”) to الخنزيرة> (“Alxnzyrp” – “the pig”) and خلفان> (“xlfAn” – “Khalfan (person name)”) to خرفان> (“xrfAn” – “crazed”).\nSocietal stratification: Some insults are associated with: certain jobs such as بواب> (“bwAb” – “doorman”) or خادم> (“xAdm” – “servant”); and specific societal components such بدوي> (“bdwy” – “bedouin”) and فلاح> (“flAH” – “farmer”).\nImmoral behavior: These insults are associated with negative moral traits or behaviors such as حقير> (“Hqyr” – “vile”), خاين> (“xAyn” – “traitor”), and منافق> (“mnAfq” – “hypocrite”).\nSexually related: They include expressions such as خول> (“xwl” – “gay”), وسخة> (“wsxp” – “prostitute”), and عرص> (“ErS” – “pimp”).\nFigure FIGREF17 shows top words with the highest valance score for individual words in the offensive tweets. Larger fonts are used to highlight words with highest score and align as well with the categories mentioned ahead in the breakdown for the offensive languages. We modified the valence score described by BIBREF1 conover2011political to magnify its value based on frequency of occurrence. The score is computed as follows:\n$V(I) = 2 \\frac{ \\frac{tf(I, C_off)}{total(C_off)}}{\\frac{tf(I, C_off)}{total(C_off)} + \\frac{tf(I, C_cln)}{total(C_cln)} } - 1$\nwhere\n$tf(I, C_i) = \\sum _{a \\in I \\bigcap C_i} [ln(Cnt(a, C_i)) + 1]$\n$total(C_i) = \\sum _{I} tf(I, C_i)$\n$Cnt(a, C_i)$ is the number of times word $a$ was used in offensive or clean tweets tweets $C_i$. In essence, we are replacing term frequencies with the natural log of the term frequencies.\nAs the figure shows, sports and politics are most dominant for offensive language including vulgar and hate speech.",

        "answer": "Using a variety of feature sets against several baselines.",
        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nTo this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines.",

        "evidence": "",
        "answer": "When choosing an electric vehicle, there are many factors to consider.  Before we get into those specific factors, let's take a quick look at the broader electric vehicle market to provide context for your choice of an electric vehicle.\n\nThe global vehicle market has made an intentional transition from combustion engine vehicles to electric powered vehicles. In that transition, here are some things to consider:\n1. This transition will continue to take place through 2030 - 2035.  This is the timeframe most of the traditional automotive original equipment manufacturers have declared that they will be 100% transitioned to electric vehicle production.  This is important because you can assume that the technology behind the electrification of automobiles will be evolving and improving over this time period.\n2. Tesla was the company that disrupted the automotive market by producing, marketing and servicing the first all-electric vehicles.  Today they have the lead in most vehicles sold in the all-electric vehicle category.  If your only criteria for choosing your electric vehicle is to choose a vehicle from the leader, you have your answer in Tesla.\n3. Fast followers to Tesla fall into two very broad categories that are important to consider in your choice of an electric vehicle:\n     1. Traditional automotive original equipment manufactures - These are the companies that have been in business of producing, marketing and servicing combustion engine vehicles. In this category, think of General Motors, Ford, Toyota, VW, BMW, Kia, Stellantis and the like.  These companies have expertise in large scale production, quality control, after sale servicing, warranty management, customer experience and have large R&D teams that have been studying vehicle electrification for many years.  In addition, they have a large dealership network to distribute and service their vehicles for your convenience.  \n     2. Startup companies - These are the companies that have recently entered the market, following Tesla's lead, in starting their own brand of all-electric vehicles.  In this category, think of Rivian, Canoo, Fisker, Arrival and Vinfast among others.  They lack the large scale production experience, facilities and employee mass of the traditional automotive manufacturers.  However, typically their strength is in being able to nimbly change, adapt, attract expertise from the automotive market and have incentives to attract customers.\n\nGiven the backdrop of the broader vehicle market, now here are some factors to consider:\n    1. Miles per charge - With is typically categorized as \"Range\". The median driving range of all-electric vehicles in 2021 is 234 miles per charge.  This factor  matters if you take long trips between convenient charges.  You also can inference that vehicles that have a range much under 234 miles per charge may not have high quality batteries.\n    2. Charging Stations - You never needed to consider this factor when buying a traditional vehicle, unless the vehicle was powered by some obscure fuel.  Now, this factor is very important to research.  You will want to consider the number of charging stations available in your area, the time per charge and options for home charging.\n    3. Maintenance and Warranty - if something does happen to your vehicle, how easy is it to find a certified center to get your repairs quickly and conveniently accomplished.\n    4. All the same factors if you were buying a traditional automotive - Price, Size, Style and incentives available for the purchase.\n\nIf you keep these factors in mind, you should have a good experience in choosing your all-electric vehicle.",

        "question": "Can discourse relations recognition be beneficial for downstream NLP applications?",
        "answer": "Recognizing discourse relations is one crucial step in discourse analysis and can be beneficial for many downstream NLP applications such as information extraction, machine translation and natural language generation.",
        "evidence": "PDTB-style discourse relations, mostly defined between two adjacent text spans (i.e., discourse units, either clauses or sentences), specify how two discourse units are logically connected (e.g., causal, contrast). Recognizing discourse relations is one crucial step in discourse analysis and can be beneficial for many downstream NLP applications such as information extraction, machine translation and natural language generation.\nCommonly, explicit discourse relations were distinguished from implicit ones, depending on whether a discourse connective (e.g., “because” and “after”) appears between two discourse units BIBREF0 . While explicit discourse relation detection can be framed as a discourse connective disambiguation problem BIBREF1 , BIBREF2 and has achieved reasonable performance (F1 score $>$ 90%), implicit discourse relations have no discourse connective and are especially difficult to identify BIBREF3 , BIBREF2 , BIBREF4 . To fill the gap, implicit discourse relation prediction has drawn significant research interest recently and progress has been made BIBREF5 , BIBREF6 by modeling compositional meanings of two discourse units and exploiting word interactions between discourse units using neural tensor networks or attention mechanisms in neural nets. However, most of existing approaches ignore wider paragraph-level contexts beyond the two discourse units that are examined for predicting a discourse relation in between.\nTo further improve implicit discourse relation prediction, we aim to improve discourse unit representations by positioning a discourse unit (DU) in its wider context of a paragraph. The key observation is that semantic meaning of a DU can not be interpreted independently from the rest of the paragraph that contains it, or independently from the overall paragraph-level discourse structure that involve the DU. Considering the following paragraph with four discourse relations, one relation between each two adjacent DUs:\n(1): [The Butler, Wis., manufacturer went public at $15.75 a share in August 1987,] $_{DU1}$ and (Explicit-Expansion) [Mr. Sim's goal then was a $29 per-share price by 1992.] $_{DU2}$ (Implicit-Expansion) [Strong earnings growth helped achieve that price far ahead of schedule, in August 1988.] $_{DU3}$ (Implicit-Comparison) [The stock has since softened, trading around $25 a share last week and closing yesterday at $23 in national over-the-counter trading.] $_{DU4}$ But (Explicit-Comparison) [Mr. Sim has set a fresh target of $50 a share by the end of reaching that goal.] $_{DU5}$ \nClearly, each DU is an integral part of the paragraph and not independent from other units. First, predicting a discourse relation may require understanding wider paragraph-level contexts beyond two relevant DUs and the overall discourse structure of a paragraph. For example, the implicit “Comparison” discourse relation between DU3 and DU4 is difficult to identify without the background information (the history of per-share price) introduced in DU1 and DU2. Second, a DU may be involved in multiple discourse relations (e.g., DU4 is connected with both DU3 and DU5 with a “Comparison” relation), therefore the pragmatic meaning representation of a DU should reflect all the discourse relations the unit was involved in. Third, implicit discourse relation prediction should benefit from modeling discourse relation continuity and patterns in a paragraph that involve easy-to-identify explicit discourse relations (e.g., “Implicit-Comparison” relation is followed by “Explicit-Comparison” in the above example).\nFollowing these observations, we construct a neural net model to process a paragraph each time and jointly build meaning representations for all DUs in the paragraph. The learned DU representations are used to predict a sequence of discourse relations in the paragraph, including both implicit and explicit relations. Although explicit relations are not our focus, predicting an explicit relation will help to reveal the pragmatic roles of its two DUs and reconstruct their representations, which will facilitate predicting neighboring implicit discourse relations that involve one of the DUs.\nIn addition, we introduce two novel designs to further improve discourse relation classification performance of our paragraph-level neural net model. First, previous work has indicated that recognizing explicit and implicit discourse relations requires different strategies, we therefore untie parameters in the discourse relation prediction layer of the neural networks and train two separate classifiers for predicting explicit and implicit discourse relations respectively. This unique design has improved both implicit and explicit discourse relation identification performance. Second, we add a CRF layer on top of the discourse relation prediction layer to fine-tune a sequence of predicted discourse relations by modeling discourse relation continuity and patterns in a paragraph.\nExperimental results show that the intuitive paragraph-level discourse relation prediction model achieves improved performance on PDTB for both implicit discourse relation classification and explicit discourse relation classification.\nRecognizing discourse relations is one crucial step in discourse analysis and can be beneficial for many downstream NLP applications such as information extraction, machine translation and natural language generation.",

        "answer": "They present a new type of knowledge graph embeddings called DOLORES that are both deep and contextualized.",
        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nIn this paper, we present a new type of knowledge graph embeddings called DOLORES that are both deep and contextualized.",

        "evidence": "Automated coding of political event data, or the record of who-did-what-to-whom within the context of political actions, has existed for roughly two decades. The approach has remained largely the same during this time, with the underlying coding procedures not updating to reflect changes in natural language processing (NLP) technology. These NLP technologies have now advanced to such a level, and with accompanying open-source software implementations, that their inclusion in the event-data coding process comes as an obvious advancement. When combined with changes in how news content is obtained, the ability to store and process large amounts of text, and enhancements based on two decades worth of event-data experience, it becomes clear that political event data is ready for a next generation dataset.\nIn this chapter, I provide the technical details for creating such a next-generation dataset. The technical details lead to a pipeline for the production of the Phoenix event dataset. The Phoenix dataset is a daily updated, near-real-time political event dataset. The coding process makes use of open-source NLP software, an abundance of online news content, and other technical advances made possible by open-source software. This enables a dataset that is transparent and replicable, while providing a more accurate coding process than previously possible. Additionally, the dataset's near-real-time nature also enables many applications that were previously impossible with batch-updated datasets, such as monitoring of ongoing events. Thus, this dataset provides a significant improvement over previous event data generation efforts.\nIn the following sections I briefly outline the history of computer-generated political event data to this point in history. I then outline what the “next generation” of event data should look like. Following this, I discuss the many facets of creating a real-time political event dataset, mainly from a technological and infrastructure standpoint. Finally, the paper concludes with a brief empirical view of the Phoenix event dataset, which is the output of the previously-discussed technological pipeline.\nThe Phoenix dataset is a daily updated, near-real-time political event dataset.",

        "evidence": "The data for our case study spans over thirty years of articles from the New York Times, from January 1986 to December 2015, and was originally collected by BIBREF68 BIBREF68. The articles come from all sections of the newspaper, such as “World\", “New York & Region\", “Opinion\", “Style\", and “Sports\". Our distributional semantic methods rely on all of the available data in order to obtain the most fine-grained understanding of the relationships between words possible. For the other techniques, we extract paragraphs containing any word from a predetermined list of LGTBQ terms (shown in Table TABREF19).\nEach acronym label was matched insensitive to case and punctuation. Some currently prominent LGBTQ terms, such as queer and trans were not included in this study, as other senses of these words were considerably more frequent in earlier years. We further filtered out paragraphs from sections that typically did not pertain to news, such as “Arts\", “Theater\", and “Movies\". While these sections could provide valuable information, we decided to focus on representation of LGBTQ groups in more news-related contexts. Furthermore, due to the original newspaper layout and subsequent digital processing, Arts sections often contained extremely long paragraphs containing numerous listings and schedules. Removing these sections substantially simplified data processing.\nA challenging question when analyzing mass media for subjective attitudes is deciding whose perspective we want to capture: an individual reporter, the institution, or society at large? In this case study, we aim to identify the institution's dehumanizing attitudes towards LGBTQ people. We represent the New York Times institution as a combination of the journalists' words in news articles, direct quotes, paraphrases from interviews, and published opinion articles. Therefore, despite our news focus, we include data from “Opinion\" sections; while opinion articles are stylistically different from traditional journalistic reporting due to more overt biases and arguments, these articles are important in constructing the institution's perspective. In addition, we consider all text in each relevant paragraph, including quotes and paraphrases, because they are important to a newspaper's framing of an issue, as particular quotes representing specific stances are intentionally included or excluded from any given article BIBREF69. However, this approach is sometimes problematic when the newspaper quotes clearly extreme positions that they are unlikely to agree with, and we discuss this issue throughout our qualitative analysis.\nWe refer to the remaining subset of the New York Times data after filtering as the LGBTQ corpus. The LGBTQ corpus consists of 93,977 paragraphs and 7.36 million tokens. However, a large increase in reporting on LGBTQ-related issues has led to a highly skewed distribution in the amount of data over years, with 1986 containing the least data (1144 paragraphs and 73,549 tokens) and 2012 containing the most (5924 paragraphs and 465,254 tokens).\nFor all experiments, we also include results for the terms American and Americans. Our primary motivation for including American(s) is to contrast changes in LGBTQ labels' representation in the New York Times with another social group label that appears in sufficiently different contexts. This ensures that the changes we find in dehumanizing language towards LGBTQ groups do not apply uniformly to all social groups, and are thus not merely an artifact of the publication's overall language change. While a natural “control\" variable would be labels such as straight or heterosexual, we found that these terms only occurred within discussions of LGBTQ communities, likely because they name socially unmarked categories. We also considered comparing LGBTQ labels to person/people, but we found that the word embedding-based experiments were particularly sensitive to syntactic forms, so we selected a word that behaves more similarly syntactically to gay and homosexual, particularly by having both nominal and adjectival uses. Nevertheless, it is important to note that American(s) is by no means a neutral control variable. Because of its in-group status for the New York Times (a U.S. institution), we expect our measurements to show that American(s) appears in more humanizing contexts than LGBTQ group labels; however, we do not expect to find substantial changes in the use of American(s) over time.\nFigure FIGREF20 shows the counts of group labels for each year in the New York Times from 1986 to 2015. For visualization purposes, only words with a total count greater than 1000 are shown. Notably, the relative frequency of homosexual decreased substantially over time, while gay, lesbian, and bisexual are more frequent in later years. We also see the emergence of the terms lgbt and transgender after 2000. Aggregated counts over all years for each LGBTQ label can be found in the Appendix.\nThe data for our case study spans over thirty years of articles from the New York Times, from January 1986 to December 2015, and was originally collected by Fast and Horvitz (2016).",

Most focus on content information and use models such as convolutional neural networks (CNN) BIBREF3 or recursive neural networks BIBREF4 . However, for user-generated posts on social media like Facebook or Twitter, there is more information that should not be ignored. On social media platforms, a user can act either as the author of a post or as a reader who expresses his or her comments about the post.\nIn this paper, we classify posts taking into account post authorship, likes, topics, and comments. In particular, users and their “likes” hold strong potential for text mining. For example, given a set of posts that are related to a specific topic, a user's likes and dislikes provide clues for stance labeling. From a user point of view, users with positive attitudes toward the issue leave positive comments on the posts with praise or even just the post's content; from a post point of view, positive posts attract users who hold positive stances. We also investigate the influence of topics: different topics are associated with different stance labeling tendencies and word usage. For example we discuss women's rights and unwanted babies on the topic of abortion, but we criticize medicine usage or crime when on the topic of marijuana BIBREF5 . Even for posts on a specific topic like nuclear power, a variety of arguments are raised: green energy, radiation, air pollution, and so on. As for comments, we treat them as additional text information. The arguments in the comments and the commenters (the users who leave the comments) provide hints on the post's content and further facilitate stance classification.\nIn this paper, we propose the user-topic-comment neural network (UTCNN), a deep learning model that utilizes user, topic, and comment information. We attempt to learn user and topic representations which encode user interactions and topic influences to further enhance text classification, and we also incorporate comment information. We evaluate this model on a post stance classification task on forum-style social media platforms. The contributions of this paper are as follows: 1. We propose UTCNN, a neural network for text in modern social media channels as well as legacy social media, forums, and message boards — anywhere that reveals users, their tastes, as well as their replies to posts. 2. When classifying social media post stances, we leverage users, including authors and likers. User embeddings can be generated even for users who have never posted anything. 3. We incorporate a topic model to automatically assign topics to each post in a single topic dataset. 4. We show that overall, the proposed method achieves the highest performance in all instances, and that all of the information extracted, whether users, topics, or comments, still has its contributions.\nIn this paper, we propose the user-topic-comment neural network (UTCNN), a deep learning model that utilizes user, topic, and comment information.",

The gloss, which defines a word sense meaning, is first utilized in Lesk algorithm BIBREF2 and then widely taken into account in many other approaches BIBREF3, BIBREF4. Besides, structural properties of semantic graphs are mainly used in graph-based algorithms BIBREF5, BIBREF6.\nTraditional supervised WSD methods BIBREF7, BIBREF8, BIBREF9 focus on extracting manually designed features and then train a dedicated classifier (word expert) for every target lemma.\nAlthough word expert supervised WSD methods perform better, they are less flexible than knowledge-based methods in the all-words WSD task BIBREF10. Recent neural-based methods are devoted to dealing with this problem. BIBREF11 present a supervised classifier based on Bi-LSTM, which shares parameters among all word types except the last layer. BIBREF10 convert WSD task to a sequence labeling task, thus building a unified model for all polysemous words. However, neither of them can totally beat the best word expert supervised methods.\nMore recently, BIBREF12 propose to leverage the gloss information from WordNet and model the semantic relationship between the context and gloss in an improved memory network. Similarly, BIBREF13 introduce a (hierarchical) co-attention mechanism to generate co-dependent representations for the context and gloss. Their attempts prove that incorporating gloss knowledge into supervised WSD approach is helpful, but they still have not achieved much improvement, because they may not make full use of gloss knowledge.\nIn this paper, we focus on how to better leverage gloss information in a supervised neural WSD system. Recently, the pre-trained language models, such as ELMo BIBREF14 and BERT BIBREF15, have shown their effectiveness to alleviate the effort of feature engineering. Especially, BERT has achieved excellent results in question answering (QA) and natural language inference (NLI). We construct context-gloss pairs from glosses of all possible senses (in WordNet) of the target word, thus treating WSD task as a sentence-pair classification problem. We fine-tune the pre-trained BERT model and achieve new state-of-the-art results on WSD task. In particular, our contribution is two-fold:\n1. We construct context-gloss pairs and propose three BERT-based models for WSD.\n2. We fine-tune the pre-trained BERT model, and the experimental results on several English all-words WSD benchmark datasets show that our approach significantly outperforms the state-of-the-art systems.\nWe fine-tune the pre-trained BERT model, and the experimental results on several English allwords WSD benchmark datasets show that our approach significantly outperforms the state-of-theart systems.",

        "answer": "The informativeness is measured by the norm of the gradient incurred by the instance.",
        "evidence": "State-of-the-art automatic speech recognition (ASR) systems BIBREF0 have large model capacities and require significant quantities of training data to generalize. Labeling thousands of hours of audio, however, is expensive and time-consuming. A natural question to ask is how to achieve better generalization with fewer training examples. Active learning studies this problem by identifying and labeling only the most informative data, potentially reducing sample complexity. How much active learning can help in large-scale, end-to-end ASR systems, however, is still an open question.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores. In particular, an utterance is considered informative if the most likely prediction has small probability BIBREF1 , or if the predictions are distributed very uniformly over the labels BIBREF2 . Though confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) BIBREF3 , where the informativeness is measured by the norm of the gradient incurred by the instance. EGL has previously been justified as intuitively measuring the expected change in a model's parameters BIBREF3 .We formalize this intuition from the perspective of asymptotic variance reduction, and experimentally, we show EGL to be superior to confidence-based methods on speech recognition tasks. Additionally, we observe that the ranking of samples scored by EGL is not correlated with that of confidence scoring, suggesting EGL identifies aspects of an instance that confidence scores cannot capture.\nIn BIBREF3 , EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular. Gradient-based methods have also found applications outside active learning. For example, BIBREF4 suggests that in stochastic gradient descent, sampling training instances with probabilities proportional to their gradient lengths can speed up convergence. From the perspective of variance reduction, this importance sampling problem shares many similarities to problems found in active learning.\nThough confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) [4], where the informativeness is measured by the norm of the gradient incurred by the instance.",

Moreover, the 5 datasets on which MPAD ranks first widely differ in training set size, number of categories, and prediction task (topic, sentiment, etc.), which indicates that MPAD can perform well in different settings.",
        "evidence": "Experimental results are shown in Table TABREF28. For the baselines, the best scores reported in each original paper are shown. MPAD reaches best performance on 7 out of 10 datasets, and is close second elsewhere. Moreover, the 7 datasets on which MPAD ranks first widely differ in training set size, number of categories, and prediction task (topic, sentiment, subjectivity), which indicates that MPAD can perform well in different settings.\nMPAD vs. hierarchical variants. On 9 datasets out of 10, one or more of the hierarchical variants outperform the vanilla MPAD architecture, highlighting the benefit of explicitly modeling the hierarchical nature of documents.\nHowever, on Subjectivity, standard MPAD outperforms all hierarchical variants. On TREC, it reaches the same accuracy. We hypothesize that in some cases, using a different graph to separately encode each sentence might be worse than using one single graph to directly encode the document. Indeed, in the single document graph, some words that never appear in the same sentence can be connected through common neighbors, as was explained in subsection SECREF7. So, this way, some notion of cross-sentence context is captured while learning representations of words, bigrams, etc. at each MP iteration. This creates better informed representations, resulting in a better document embedding. With the hierarchical variants, on the other hand, each sentence vector is produced in isolation, without any contextual information about the other sentences in the document. Therefore, the final sentence embeddings might be of lower quality, and as a group might also contain redundant/repeated information. When the sentence vectors are finally combined into a document representation, it is too late to take context into account.\nTo understand the impact of some hyperparameters on performance, we conducted additional experiments on the Reuters, Polarity, and IMDB datasets, with the non-hierarchical version of MPAD. Results are shown in Table TABREF29.\nNumber of MP iterations. First, we varied the number of message passing iterations from 1 to 4. We can clearly see in Table TABREF29 that having more iterations improves performance. We attribute this to the fact that we are reading out at each iteration from 1 to $T$ (see Eq. DISPLAY_FORM18), which enables the final graph representation to encode a mixture of low-level and high-level features. Indeed, in initial experiments involving readout at $t$=$T$ only, setting $T\\ge 2$ was always decreasing performance, despite the GRU-based updates (Eq. DISPLAY_FORM14). These results were consistent with that of BIBREF53 and BIBREF9, who both are reading out only at $t$=$T$ too. We hypothesize that node features at $T\\ge 2$ are too diffuse to be entirely relied upon during readout. More precisely, initially at $t$=0, node representations capture information about words, at $t$=1, about their 1-hop neighborhood (bigrams), at $t$=2, about compositions of bigrams, etc. Thus, pretty quickly, node features become general and diffuse. In such cases, considering also the lower-level, more precise features of the earlier iterations when reading out may be necessary.\nUndirected edges. On Reuters, using an undirected graph leads to better performance, while on Polarity and IMDB, it is the opposite. This can be explained by the fact that Reuters is a topic classification task, for which the presence or absence of some patterns is important, but not necessarily the order in which they appear, while Polarity and IMDB are sentiment analysis tasks. To capture sentiment, modeling word order is crucial, e.g., in detecting negation.\nNo master node. Removing the master node deteriorates performance across all datasets, clearly showing the value of having such a node. We hypothesize that since the special document node is connected to all other nodes, it is able to encode during message passing a summary of the document.\nNo renormalization. Here, we do not use the renormalization trick of BIBREF9 during MP (see subsection SECREF10). That is, Eq. DISPLAY_FORM11 becomes $\\mathbf {M}^{t+1} = \\textsc {MLP}^{t+1}\\big (\\mathbf {A}\\mathbf {H}^{t}\\big )$. In other words, instead of computing a weighted average of the incoming neighbors' feature vectors, we compute a weighted sum of them. Unlike the mean, which captures distributions, the sum captures structural information BIBREF14. As shown in Table TABREF29, using sum instead of mean decreases performance everywhere, suggesting that in our application, capturing the distribution of neighbor representations is more important that capturing their structure. We hypothesize that this is the case because statistical word co-occurrence networks tend to have similar structural properties, regardless of the topic, polarity, sentiment, etc. of the corresponding documents.\nNeighbors-only. In this experiment, we replaced the GRU combine function (see Eq. DISPLAY_FORM14) with the identity function. That is, we simply have $\\mathbf {H}^{t+1}$=$\\mathbf {M}^{t+1}$. Since $\\mathbf {A}$ has zero diagonal, by doing so, we completely ignore the previous feature of the node itself when updating its representation. That is, the update is based entirely on its neighbors. Except on Reuters (almost no change), performance always suffers, stressing the need to take into account the root node during updates, not only its neighborhood.\nMPAD reaches best performance on 5 out of 10 datasets, and is close second elsewhere. Moreover, the 5 datasets on which MPAD ranks first widely differ in training set size, number of categories, and prediction task (topic, sentiment, etc.), which indicates that MPAD can perform well in different settings.",

The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).\nOganesson (Og) is a synthetically produced highly radioactive element. Although IUPAC has used the term \"noble gas\" interchangeably with \"group 18\" and thus included oganesson, it may not be significantly chemically noble and is predicted to break the trend and be reactive due to relativistic effects. Because of the extremely short 0.7 ms half-life of its only known isotope, its chemistry has not yet been investigated.\nFor the first six periods of the periodic table, the noble gases are exactly the members of group 18. Noble gases are typically highly unreactive except when under particular extreme conditions. The inertness of noble gases makes them very suitable in applications where reactions are not wanted. For example, argon is used in incandescent lamps to prevent the hot tungsten filament from oxidizing; also, helium is used in breathing gas by deep-sea divers to prevent oxygen, nitrogen and carbon dioxide toxicity.\nThe properties of the noble gases can be well explained by modern theories of atomic structure: Their outer shell of valence electrons is considered to be \"full\", giving them little tendency to participate in chemical reactions, and it has been possible to prepare only a few hundred noble gas compounds. The melting and boiling points for a given noble gas are close together, differing by less than 10 °C (18 °F); that is, they are liquids over only a small temperature range.\nNeon, argon, krypton, and xenon are obtained from air in an air separation unit using the methods of liquefaction of gases and fractional distillation. Helium is sourced from natural gas fields that have high concentrations of helium in the natural gas, using cryogenic gas separation techniques, and radon is usually isolated from the radioactive decay of dissolved radium, thorium, or uranium compounds. Noble gases have several important applications in industries such as lighting, welding, and space exploration. A helium-oxygen breathing gas is often used by deep-sea divers at depths of seawater over 55 m (180 ft).

        "evidence": "For an ever increasing spectrum of applications (e.g., medical text analysis, opinion mining, sentiment analysis, social media text analysis, customer intelligence, fraud analytics etc.) mining and analysis of unstructured natural language text data is necessary BIBREF0, BIBREF1, BIBREF2.\nOne of key challenge while designing such text analytics (TA) applications is to identify right set of features. For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nIn this paper, we aim to present an approach towards automating NLP feature engineering.",

        "evidence": "In our evaluation, we followed the same LiveQA guidelines with the highest possible rigor. In particular, we consulted with NIST assessors who provided us with the paraphrases of the test questions that they used to judge the answers. Our IAA on the answers rating was also high compared to related tasks, with an 88.5% F1 agreement with the exact four categories and a 94.3% agreement when reducing the categories to two: “Correct” and “Incorrect” answers. Our results show that RQE improves the overall performance and exceeds the best results in the medical LiveQA'17 challenge by a factor of 29.8%. This performance improvement is particularly interesting as:\nOur answer source has only 47K question-answer pairs when LiveQA participating systems relied on much larger collections, including the World Wide Web.\nOur system answered one subquestion at most when many LiveQA test questions had several subquestions.\nThe latter observation, (b), makes the hybrid IR+RQE approach even more promising as it gives it a large potential for the improvement of answer completeness.\nThe former observation, (a), provides another interesting insight: restricting the answer source to only reliable collections can actually improve the QA performance without losing coverage (i.e., our QA approach provided at least one answer to each test question and obtained the best relevance score).\nIn another observation, the assessors reported that many of the returned answers had a correct question type but a wrong focus, which indicates that including a focus recognition module to filter such wrong answers can improve further the QA performance in terms of precision. Another aspect that was reported is the repetition of the same (or similar) answer from different websites, which could be addressed by improving answer selection with inter-answer comparisons and removal of near-duplicates. Also, half of the LiveQA test questions are about Drugs, when only two of our resources are specialized in Drugs, among 12 sub-collections overall. Accordingly, the assessors noticed that the performance of the QA systems was better on questions about diseases than on questions about drugs, which suggests a need for extending our medical QA collection with more information about drugs and associated question types.\nWe also looked closely at the private websites used by the LiveQA-Med annotators to provide some of the reference answers for the test questions. For instance, the ConsumerLab website was useful to answer a question about the ingredients of a Drug (COENZYME Q10). Similarly, the eHealthMe website was used to answer a test question asking about interactions between two drugs (Phentermine and Dicyclomine) when no information was found in DailyMed. eHealthMe provides healthcare big data analysis and private research and studies including self-reported adverse drug effects by patients.\nBut the question remains on the extent to which such big data and other private websites could be used to automatically answer medical questions if information is otherwise unavailable. Unlike medical professionals, patients do not necessarily have the knowledge and tools to validate such information. An alternative approach could be to put limitations on medical QA systems in terms of the questions that can be answered (e.g. \"What is my diagnosis for such symptoms\") and build classifiers to detect such questions and warn the users about the dangers of looking for their answers online.\nMore generally, medical QA systems should follow some strict guidelines regarding the goal and background knowledge and resources of each system in order to protect the consumers from misleading or harmful information. Such guidelines could be based (i) on the source of the information such as health and medical information websites sponsored by the U.S. government, not-for-profit health or medical organizations, and medical university centers, or (ii) on conventions such as the code of conduct of the HON Foundation (HONcode) that addresses the reliability and usefulness of medical information on the Internet.\nOur experiments show that limiting the number of answer sources with such guidelines is not only feasible, but it could also enhance the performance of the QA system from an information retrieval perspective.\nOur results show that RQE improves the overall performance and exceeds the best results in the medical LiveQA’17 challenge by a factor of 29.8%.",

        "answer": "AWD is a system that without driver intervention, shifts power between the rear and front wheels. This system is typically found on light-duty SUVs or passenger cars. The AWD drive system is designed for mild inclement weather conditions such as light snow, ice and rain. It is not designed for off-roading or severe weather conditions such as heavy snow or mud. This is where the 4WD system comes into the picture. \n\n4WD is a system that includes a transfer case that directly applies power to the rear axle, both front and rear axles and in some cases, only to the front axle. In addition, some 4WD systems include lower gear ratio options, locking hubs and lockers in the axles that force an equal amount of power to each wheel. All this taken together enables a 4WD system to enable a vehicle to navigate through deep snow, mud, over rocks and other obstacles with ease. The 4WD system is most commonly found on trucks, Jeeps and other purpose-built vehicles designed for heavy-duty use, whether for work or pleasure.",

        "question": "What is the approach proposed by authors for hate speech understanding?",
        "answer": "It is a transfer learning approach using a combination of the unsupervised pre-trained model BERT and some new supervised fine-tuning strategies.",
        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT [4] and some new supervised fine-tuning strategies.",

        "question": "What are the major producing regions of figs around the world today?",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

In the figure FIGREF1, the arrow that leaves the unit (2) towards the unit (1) symbolizes that the unit (2) is the satellite of the unit (1), which is the core in a “Concession” relationship.

        "question": "In their method, is pre-generating decoder state statistics needed?",
        "answer": "No.",
        "evidence": "Speech input is now a common feature for smart devices. In many cases, the user's query involves entities such as a name from a contact list, a location, or a music title. Recognizing entities is particularly challenging for speech recognition because many entities are infrequent or out of the main vocabulary of the system. One way to improve performance is such cases is through the use of a personal language model (LM) which contains the expected user-specific entities. Because each user can have their own personalized LM, it is vital that the speech decoder be able to efficiently load the model on the fly, so it can be used in decoding, without any noticeable increase in latency.\nMany state-of-the-art speech recognition decoders are based on the weighted finite state transducer (WFST) paradigm BIBREF0, BIBREF1. A conventional WFST decoder searches a statically composed $H C L G$ graph, where $H$ is the graph that translates HMM states to CD phones, $C$ translates CD phones to graphemes, $L$ translates graphemes to words and $G$ is graph that represents the language model. Using a statically composed graph has two limitations. First, it is both compute and memory intensive when the vocabulary and LM are large. Second, the static graph approach makes it hard to handle personalized language models BIBREF2. Many common tasks a user may want to perform with a voice assistant such as making phone calls, messaging to a specific contact or playing favorite music require a personalized language model. A dynamic WFST decoder is better suited for such cases. As denoted in Eq (DISPLAY_FORM1), in a dynamic WFST decoder, $HCL$ is composed and optimized offline, while $G$ is composed on the fly with lazy (on-demand) composition, denoted as $\\circ $.\nTo handle dynamic entities, a class LM $G_c$ is normally used as background $G$ and a personalized LM $G_p$ is replaced on-the-fly, before applying lazy composition.\nSince the non-terminal states are composed on-the-fly, it means the states of recognition FST will also contain personalized information that cannot be used by other users or service threads.\nIn previous work, a method was proposed to do a pre-initialized composition for a non-class LM BIBREF3. However, it the dynamic part is still expanded on-the-fly. In this work, we propose two improvements in order to best leverage class language models. First, we use simpler methods for pre-initialization which do not need to pre-generate decoder state statistics. Second, we propose a two-layer pre-initialization mechanism that also avoids performing dynamic expansion on per user basis. In the two-layer pre-initialization method, we make use of a class LM with class tag. We build a personalized FST that contains the members of the class for each user. Using the FST replacement algorithm, we obtain a personalized language transducer BIBREF4. We perform a pre-composition for all FST states whose transitions do not contain class tags. By doing so, the actual on-demand composition is only required for the states in personalized FST. For a multi-threaded service, the pre-composed FST can be shared by all threads, since it does not contain personalized FST states (non-terminals). The personalized part will be shared for all utterances from the same user, which will take full advantage of memory usage.\nUnlike the previous pre-initialization approach that is based on calculating the state statistics BIBREF3, our simplified pre-initialization methods do not rely on pre-calculated state frequencies. Instead, we directly expand the graph with breadth-first search or through a data-driven approach where a small numbers of utterances are processed by the decoder offline. We found that both methods are effective, but the data-driven approach outperforms the breadth first search algorithm. Both methods can be combined to achieve the best performance. Through a series of experiments on a speech recognition task for the calling domain, we found that pre-initialization on the public graph speeds up the decoding time by a factor of three. Futhermore, sharing the private graph further reduces decoding time and results in factor of five improvement in efficiency.\nIn this work, we propose two improvements in order to best leverage class language models. First, we use simpler methods for pre-initialization which do not need to pre-generate decoder state statistics.",

She was one of the most influential professors in commercial and bankruptcy law before beginning her political career. Warren has written 12 books and more than 100 articles.\n\nWarren's first foray into public policy began in 1995, when she worked to oppose what eventually became a 2005 act restricting bankruptcy access for individuals. During the late 2000s, her national profile grew after her forceful public stances in favor of more stringent banking regulations after the financial crisis of 2007–08. She served as chair of the Congressional Oversight Panel of the Troubled Asset Relief Program, and proposed and established the Consumer Financial Protection Bureau, for which she served as the first special advisor under President Barack Obama.\n\nIn 2012, Warren defeated incumbent Republican Scott Brown and became the first female U.S. senator from Massachusetts. She won re-election by a wide margin in 2018, defeating Republican nominee Geoff Diehl. On February 9, 2019, Warren announced her candidacy in the 2020 United States presidential election.

        "evidence": "Lexical analysis, syntactic analysis, semantic analysis, disclosure analysis and pragmatic analysis are five main steps in natural language processing BIBREF0 , BIBREF1 . While morphology is a basic task in lexical analysis of English, word segmentation is considered a basic task in lexical analysis of Vietnamese and other East Asian languages processing. This task is to determine borders between words in a sentence. In other words, it is segmenting a list of tokens into a list of words such that words are meaningful.\nWord segmentation is the primary step in prior to other natural language processing tasks i. e., term extraction and linguistic analysis (as shown in Figure 1). It identifies the basic meaningful units in input texts which will be processed in the next steps of several applications. For named entity recognization BIBREF2 , word segmentation chunks sentences in input documents into sequences of words before they are further classified in to named entity classes. For Vietnamese language, words and candidate terms can be extracted from Vietnamese copora (such as books, novels, news, and so on) by using a word segmentation tool. Conformed features and context of these words and terms are used to identify named entity tags, topic of documents, or function words. For linguistic analysis, several linguistic features from dictionaries can be used either to annotating POS tags or to identifying the answer sentences. Moreover, language models can be trained by using machine learning approaches and be used in tagging systems, like the named entity recognization system of Tran et al. BIBREF2 .\nMany studies forcus on word segmentation for Asian languages, such as: Chinese, Japanese, Burmese (Myanmar) and Thai BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . Approaches for word segmentation task are variety, from lexicon-based to machine learning-based methods. Recently, machine learning-based methods are used widely to solve this issue, such as: Support Vector Machine or Conditional Random Fields BIBREF7 , BIBREF8 . In general, Chinese is a language which has the most studies on the word segmentation issue. However, there is a lack of survey of word segmentation studies on Asian languages and Vietnamese as well. This paper aims reviewing state-of-the-art word segmentation approaches and systems applying for Vietnamese. This study will be a foundation for studies on Vietnamese word segmentation and other following Vietnamese tasks as well, such as part-of-speech tagger, chunker, or parser systems.\nThere are several studies about the Vietnamese word segmentation task over the last decade. Dinh et al. started this task with Weighted Finite State Transducer (WFST) approach and Neural Network approach BIBREF9 . In addition, machine learning approaches are studied and widely applied to natural language processing and word segmentation as well. In fact, several studies used support vector machines (SVM) and conditional random fields (CRF) for the word segmentation task BIBREF7 , BIBREF8 . Based on annotated corpora and token-based features, studies used machine learning approaches to build word segmentation systems with accuracy about 94%-97%.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation. A all sided review of word segmentation will help next studies on Vietnamese natural language processing tasks have an up-to-date guideline and choose the most suitable solution for the task. The remaining part of the paper is organized as follows. Section II discusses building corpus in Vietnamese, containing linguistic issues and the building progress. Section III briefly mentions methods to model sentences and text in machine learning systems. Next, learning models and approaches for labeling and segmenting sequence data will be presented in Section IV. Section V mainly addresses two existing toolkits, vnTokenizer and JVnSegmenter, for Vietnamese word segmentation. Several experiments based on mentioned approaches and toolkits are described in Section VI. Finally, conclusions and future works are given in Section VII.\nThis study will be a foundation for studies on Vietnamese word segmentation and other following Vietnamese tasks as well, such as part-ofspeech tagger, chunker, or parser systems.",

        "answer": "Yes.",
        "evidence": "The majority of the English text available worldwide is generated by non-native speakers BIBREF0 . Such texts introduce a variety of challenges, most notably grammatical errors, and are of paramount importance for the scientific study of language acquisition as well as for NLP. Despite the ubiquity of non-native English, there is currently no publicly available syntactic treebank for English as a Second Language (ESL).\nTo address this shortcoming, we present the Treebank of Learner English (TLE), a first of its kind resource for non-native English, containing 5,124 sentences manually annotated with POS tags and dependency trees. The TLE sentences are drawn from the FCE dataset BIBREF1 , and authored by English learners from 10 different native language backgrounds. The treebank uses the Universal Dependencies (UD) formalism BIBREF2 , BIBREF3 , which provides a unified annotation framework across different languages and is geared towards multilingual NLP BIBREF4 . This characteristic allows our treebank to support computational analysis of ESL using not only English based but also multilingual approaches which seek to relate ESL phenomena to native language syntax.\nWhile the annotation inventory and guidelines are defined by the English UD formalism, we build on previous work in learner language analysis BIBREF5 , BIBREF6 to formulate an additional set of annotation conventions aiming at a uniform treatment of ungrammatical learner language. Our annotation scheme uses a two-layer analysis, whereby a distinct syntactic annotation is provided for the original and the corrected version of each sentence. This approach is enabled by a pre-existing error annotation of the FCE BIBREF7 which is used to generate an error corrected variant of the dataset. Our inter-annotator agreement results provide evidence for the ability of the annotation scheme to support consistent annotation of ungrammatical structures.\nFinally, a corpus that is annotated with both grammatical errors and syntactic dependencies paves the way for empirical investigation of the relation between grammaticality and syntax. Understanding this relation is vital for improving tagging and parsing performance on learner language BIBREF8 , syntax based grammatical error correction BIBREF9 , BIBREF10 , and many other fundamental challenges in NLP. In this work, we take the first step in this direction by benchmarking tagging and parsing accuracy on our dataset under different training regimes, and obtaining several estimates for the impact of grammatical errors on these tasks.\nTo summarize, this paper presents three contributions. First, we introduce the first large scale syntactic treebank for ESL, manually annotated with POS tags and universal dependencies. Second, we describe a linguistically motivated annotation scheme for ungrammatical learner English and provide empirical support for its consistency via inter-annotator agreement analysis. Third, we benchmark a state of the art parser on our dataset and estimate the influence of grammatical errors on the accuracy of automatic POS tagging and dependency parsing.\nThe remainder of this paper is structured as follows. We start by presenting an overview of the treebank in section SECREF2 . In sections SECREF3 and SECREF4 we provide background information on the annotation project, and review the main annotation stages leading to the current form of the dataset. The ESL annotation guidelines are summarized in section SECREF5 . Inter-annotator agreement analysis is presented in section SECREF6 , followed by parsing experiments in section SECREF7 . Finally, we review related work in section SECREF8 and present the conclusion in section SECREF9 .\nFirst, we introduce the first large scale syntactic treebank for ESL, manually annotated with POS tags and universal dependencies.",

        "evidence": "Word Sense Disambiguation (WSD) is an important problem in Natural Language Processing (NLP), both in its own right and as a stepping stone to other advanced tasks in the NLP pipeline, applications such as machine translation BIBREF0 and question answering BIBREF1 . WSD specifically deals with identifying the correct sense of a word, among a set of given candidate senses for that word, when it is presented in a brief narrative (surrounding text) which is generally referred to as context. Consider the ambiguous word `cold'. In the sentence “He started to give me a cold shoulder after that experiment”, the possible senses for cold can be cold temperature (S1), a cold sensation (S2), common cold (S3), or a negative emotional reaction (S4). Therefore, the ambiguous word cold is specified along with the sense set {S1, S2, S3, S4} and our goal is to identify the correct sense S4 (as the closest meaning) for this specific occurrence of cold after considering - the semantic and the syntactic information of - its context.\nIn this effort, we develop our supervised WSD model that leverages a Bidirectional Long Short-Term Memory (BLSTM) network. This network works with neural sense vectors (i.e. sense embeddings), which are learned during model training, and employs neural word vectors (i.e. word embeddings), which are learned through an unsupervised deep learning approach called GloVe (Global Vectors for word representation) BIBREF2 for the context words. By evaluating our one-model-fits-all WSD network over the public gold standard dataset of SensEval-3 BIBREF3 , we demonstrate that the accuracy of our model in terms of F-measure is comparable with the state-of-the-art WSD algorithms'.\nWe outline the organization of the rest of the paper as follows. In Section 2, we briefly explore earlier efforts in WSD and discuss recent approaches that incorporate deep neural networks and word embeddings. Our main model that employs BLSTM with the sense and word embeddings is detailed in Section 3. We then present our experiments and results in Section 4 supported by a discussion on how to avoid some drawbacks of the current model in order to achieve higher accuracies and demand less number of training data which is desirable. Finally, in Section 5, we conclude with some future research directions for the construction of sense embeddings as well as applications of such model in other domains such as biomedicine.\nIn this effort, we develop our supervised WSD model that leverages a Bidirectional Long Short-Term Memory (BLSTM) network.",

        "question": "Given these paragraphs about Large language models, what are relevant dimensions influencing the skill with which they accomplish tasks, and the range of tasks at which they are capable?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

        "question": "Do the Transformer-based models perform strongest on pronouns with intra-segmental antecedent?",
        "answer": "Yes, they do.",
        "evidence": "The BLEU scores in Table TABREF30 show a moderate improvement for most context-aware systems. This suggests that the architectural changes for the context-aware models do not degrade overall translation quality. The contrastive evaluation on our test set on the other hand shows a clear increase in the accuracy of pronoun translation: The best model s-hier-to-2.tied achieves a total of +16 percentage points accuracy on the test set over the baseline, see Table TABREF31 .\nTable TABREF32 shows that context-aware models perform better than the baseline when the antecedent is outside the current sentence. In our experiments, all context-aware models consider one preceding sentence as context. The evaluation according to the distance of the antecedent in Table TABREF35 confirms that the subset of sentences with antecedent distance 1 benefits most from the tested context-aware models (up to +20 percentage points accuracy). However, we note two surprising patterns:\nThe first observation can be explained by the distribution of German pronouns in the test set. The further away the antecedent, the higher the percentage of it INLINEFORM0 es cases, which are the majority class, and thus the class that will be predicted most often if evidence for other classes is lacking. We speculate that this is due to our more permissive extraction heuristics for it INLINEFORM1 es.\nWe attribute the second observation to the existence of coreference chains where the preceding sentence contains a pronoun that refers to the same nominal antecedent as the pronoun in the current sentence. Consider the example in Table TABREF36 : The nominal antecedent of it in the current sentence is door, Tür in German with feminine gender. The nominal antecedent occurs two sentences before the current sentence, but the German sentence in between contains the pronoun sie, which is a useful signal for the context-aware models, even though they cannot know the nominal antecedent.\nNote that only models aware of target-side context can benefit from such circumstances: The s-hier models as well as the Transformer model by BIBREF8 only see source side context, which results in lower accuracy if the distance to the antecedent is INLINEFORM0 1, see Table TABREF35 .\nWhile such coreference chains complicate the interpretation of the results, we note that improvements on inter-sentential anaphora with antecedent distance INLINEFORM0 are relatively small (compared to distance 1), and that performance is still relatively poor (especially for the minority classes er and sie). We encourage evaluation of wider-context models on this subset, which is still large thanks to the size of the full test set.\nRegarding the comparison of different context-aware architectures, our results demonstrate the effectiveness of parameter sharing between the main encoder (or decoder) and the contextual encoder. We observe an improvement of 5 percentage points from s-hier-to-2 to s-hier-to-2.tied, and 4 percentage points from s-t-hier to s-t-hier.tied. Context encoders introduce a large number of extra parameters, while inter-sentential context is only relevant for a relatively small number of predictions. We hypothesize that the training signal is thus too weak to train a strong contextual encoder in an end-to-end fashion without parameter sharing. Our results also confirm the finding by BIBREF9 that multi-encoder architectures, specifically s-hier-to-2(.tied), can outperform a simple concatenation system in the translation of coreferential pronouns.\nThe Transformer-based models perform strongest on pronouns with intra-segmental antecedent, outperforming the recurrent baseline by 9–18 percentage points. This is likely an effect of increased model depth and the self-attentional architecture in this set of experiments. The model by BIBREF8 only uses source context, and outperforms the most comparable RNN system, s-hier.tied. However, the Transformer-based concat22 slightly underperforms the RNN-based concat22, and we consider it future research how to better exploit target context with Transformer-based models.\nThe Transformer-based models perform strongest on pronouns with intra-segmental antecedent, outperforming the recurrent baseline by 9–18 percentage points.",

        "question": "Based on the provided passage, extract the main reason that the Rocky Mountain Locust went extinct.",
        "evidence": "Rocky Mountain locusts caused farm damage in Maine from 1743 to 1756 and Vermont in 1797–1798. The locusts became more of a problem in the 19th century, as farming expanded westward into the grasshoppers' favored habitat. Outbreaks of varying severity emerged in 1828, 1838, 1846, and 1855, affecting areas throughout the West. Plagues visited Minnesota in 1856–1857 and again in 1865, and Nebraska suffered repeated infestations between 1856 and 1874.\n\n\n1875 cartoon by Henry Worrall showing Kansas farmers battling giant grasshoppers\nThe last major swarms of Rocky Mountain locust were between 1873 and 1877, when the locust caused $200 million in crop damage in Colorado, Kansas, Minnesota, Missouri, Nebraska and other states. One farmer reported that the locusts seemed \"like a great white cloud, like a snowstorm, blocking out the sun like vapor\". The locusts ate not only the grass and valuable crops, but also leather, wood, sheep's wool, and—in extreme cases—even clothes off peoples' backs. Trains were sometimes brought to a halt after skidding over large numbers of locusts run over on the rails. As the swarms worsened, farmers attempted to control them using gunpowder, fires (sometimes dug in trenches to burn as many of the locusts as possible), smearing them with \"hopperdozers\", a type of plow device pulled behind horses that had a shield that knocked jumping locusts into a pan of liquid poison or fuel, even sucking them into vacuum cleaner–like contraptions, but all of these were ultimately ineffective in stopping the hordes. Charles Valentine Riley, a Missouri entomologist, came up with a recipe for locusts seasoned with salt and pepper and pan-fried in butter. The recipe sold, but some stated that they \"would just as soon starve as eat those horrible creatures\". Farmers finally responded in force to the swarm's destruction; an 1877 Nebraska law said that anyone between the ages of 16 and 60 had to work at least two days eliminating locusts at hatching time or face a $10 fine. That same year Missouri offered a bounty of $1 a bushel for locusts collected in March, 50 cents a bushel in April, 25 cents in May, and 10 cents in June. Other Great Plains states made similar bounty offers. In the 1880s farmers had recovered sufficiently from their locust woes to be able to send carloads of corn to flood victims in Ohio. They also switched to such resilient crops as winter wheat, which matured in the early summer, before locusts were able to migrate. These new agricultural practices effectively reduced the threat of locusts and greatly contributed to the species' downfall.\n\nIt has been hypothesized that plowing and irrigation by settlers as well as trampling by cattle and other farm animals near streams and rivers in the Rocky Mountains destroyed their eggs in the areas they permanently lived, which ultimately caused their demise. For example, reports from this era suggest that farmers killed over 150 egg cases per square inch while plowing, harrowing or flooding.: 11–12  It appeared that this species lived and reproduced in the prairie only temporarily during swarming years, with each generation being smaller than the previous one and swarming ever further from the Rocky Mountains, while the permanent breeding grounds of this species seemed to be restricted to an area somewhere between 3 and 3,000 square miles of sandy soils near streams and rivers in the Rockies, which coincided with arable and pastoral lands exploited by settlers.\n\nBecause locusts are a form of grasshopper that appear when grasshopper populations reach high densities, it was theorized that M. spretus might not be extinct, that \"solitary phase\" individuals of a migratory grasshopper might be able to turn into the Rocky Mountain locust given the right environmental conditions; however, breeding experiments using many grasshopper species in high-density environments failed to invoke the famous insect. The status of M. spretus as a distinct species was confirmed by a 2004 DNA analysis of North American species of the genus Melanoplus.\n\nMelanoplus spretus was formally declared extinct by the IUCN in 2014. It has been suggested that the now critically endangered Eskimo curlew fed on the locust during its spring migration and that its extinction may have added to the pressures on already declining curlew populations including hunting and the conversion of its grassland habitat to agriculture.",

        "evidence": "Different theorists have different categorizations and conceptualizations of defence mechanisms. Large reviews of theories of defence mechanisms are available from Paulhus, Fridhandler and Hayes (1997) and Cramer (1991). The Journal of Personality published a special issue on defence mechanisms (1998).\n\nIn the first definitive book on defence mechanisms, The Ego and the Mechanisms of Defence (1936), Anna Freud enumerated the ten defence mechanisms that appear in the works of her father, Sigmund Freud: repression, regression, reaction formation, isolation, undoing, projection, introjection, turning against one's own person, reversal into the opposite, and sublimation or displacement.\n\nSigmund Freud posited that defence mechanisms work by distorting id impulses into acceptable forms, or by unconscious or conscious blockage of these impulses. Anna Freud considered defense mechanisms as intellectual and motor automatisms of various degrees of complexity, that arose in the process of involuntary and voluntary learning.\n\nAnna Freud introduced the concept of signal anxiety; she stated that it was \"not directly a conflicted instinctual tension but a signal occurring in the ego of an anticipated instinctual tension\". The signalling function of anxiety was thus seen as crucial, and biologically adapted to warn the organism of danger or a threat to its equilibrium. The anxiety is felt as an increase in bodily or mental tension, and the signal that the organism receives in this way allows for the possibility of taking defensive action regarding the perceived danger.\n\nBoth Freuds studied defence mechanisms, but Anna spent more of her time and research on five main mechanisms: repression, regression, projection, reaction formation, and sublimation. All defence mechanisms are responses to anxiety and how the consciousness and unconscious manage the stress of a social situation.\n\nRepression: when a feeling is hidden and forced from the consciousness to the unconscious because it is seen as socially unacceptable\nRegression: falling back into an early state of mental/physical development seen as \"less demanding and safer\"\nProjection: possessing a feeling that is deemed as socially unacceptable and instead of facing it, that feeling or \"unconscious urge\" is seen in the actions of other people\nReaction formation: acting the opposite way that the unconscious instructs a person to behave, \"often exaggerated and obsessive\". For example, if a wife is infatuated with a man who is not her husband, reaction formation may cause her to – rather than cheat – become obsessed with showing her husband signs of love and affection.\nSublimation: seen as the most acceptable of the mechanisms, an expression of anxiety in socially acceptable ways\nOtto F. Kernberg (1967) developed a theory of borderline personality organization of which one consequence may be borderline personality disorder. His theory is based on ego psychological object relations theory. Borderline personality organization develops when the child cannot integrate helpful and harmful mental objects together. Kernberg views the use of primitive defence mechanisms as central to this personality organization. Primitive psychological defences are projection, denial, dissociation or splitting and they are called borderline defence mechanisms. Also, devaluation and projective identification are seen as borderline defences.\n\nIn George Eman Vaillant's (1977) categorization, defences form a continuum related to their psychoanalytical developmental level.[non-primary source needed] They are classified into pathological, immature, neurotic and \"mature\" defences.\n\nRobert Plutchik's (1979) theory views defences as derivatives of basic emotions, which in turn relate to particular diagnostic structures. According to his theory, reaction formation relates to joy (and manic features), denial relates to acceptance (and histrionic features), repression to fear (and passivity), regression to surprise (and borderline traits), compensation to sadness (and depression), projection to disgust (and paranoia), displacement to anger (and hostility) and intellectualization to anticipation (and obsessionality).\n\nThe Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) published by the American Psychiatric Association (1994) includes a tentative diagnostic axis for defence mechanisms. This classification is largely based on Vaillant's hierarchical view of defences, but has some modifications. Examples include: denial, fantasy, rationalization, regression, isolation, projection, and displacement.",

Generally, defense mechanisms are human responses responses to anxiety and how the consciousness and unconscious manage the stress of a social situation.

Her 2006 self-titled debut album made her the first female country artist to write a U.S. platinum-certified album.\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history.

In the revised manuscript, we now evaluate the proposed approach using two additional closed-form ZSL models as the probe models, and report the results in the newly added Table 2. As discussed in Section 4.1, we observe improvements via sample probing in 11 out of 12 cases, which supports the general applicability of the method.",
        "evidence": "In this subsection, we discuss our main experimental results. As we observe that the results are heavily influenced by hyper-parameter tuning strategy, our main goal throughout our experiments is the validation of the proposed sample probing idea by integrating it into strong generative GZSL baselines, and then comparing results using the same tuning methodology. Using this principle, we present two main types of analysis: (i) the evaluation of the proposed approach using ESZSL as the probe model in combination with a number of generative GZSL models, and (ii) the evaluation of alternative closed-form probe models within our framework.\nGenerative GZSL models with sample probing. To evaluate the sample probing approach as a general technique to improve generative model training, we integrate it to four recent generative GZSL approaches: conditional Wasserstein GAN (cWGAN), LisGAN, TF-VAEGAN and FREE. We additionally report results for the variant of TF-VAEGAN with the fine-tuned representations (TF-VAEGAN-FT), as it is the only one among them with reported fine-tuning results.\nFor the cWGAN, we follow the implementation details described in Sariyildiz & Cinbis (2019), and tune hyper-parameters using our policy. For LisGAN, TF-VAEGAN and FREE models, we use the official repositories shared by their respective authors. We use the version of TF-VAEGAN without feedback loop, for simplicity, as the model yields excellent performance with and without feedback loop. In all models (except cWGAN), we only re-tune the number of training iterations of the original models using our hyper-parameter tuning policy, to make the re-Table: Evaluation of sample probing with multiple generative GZSL models on four benchmark datasets. Each row pair shows the effect of adding sample probing to a particular generative GZSL model, using ESZSL as the closed-form probe model. We use the same hyper-parameter optimization policy in all cases to make results comparable. sults comparable, as it is unclear how the original values were obtained. We keep all remaining hyper-parameters unchanged to remain as close as possible to the original implementations.\nThe results over the four benchmark datasets are presented in Table. In terms of the h-scores, we observe improvements in 17 out of 19 cases, at varying degrees (up to 4.6 points ). Only in two cases we observe a slight degradation (maximum of 0.2 points) in performance. Overall, these improvements over already strong and state-of-the-art (or competitive) baselines validate the effectiveness of the proposed sample probing approach, suggesting that it is a valid method towards end-to-end learning of generative GZSL models directly optimized for synthetic train data generation purposes.\nSample probing with alternative closed-form models. We now evaluate our approach with different closed-form probe models, specifically ESZSL, Sem2Vis and Vis2Sem, as described in Section 3.3. For these experiments, we use the TF-VAEGAN as the base generative model.\nThe results with four configurations over four benchmark datasets are presented in Table. First of all, in terms of h-scores, we observe considerable performance variations across the probe models and datasets: Sem2Vis performs the best on CUB (+0.9 over the baseline), ESZSL provides a clear gain on FLO (+4.6) and a relative improvement on AWA (+0.3), and Vis2Sem improves the most on SUN (+1.8). These results suggest that sample probe alternatives have their own advantages and disadvantages, and their performances can be data dependent. Therefore, in a practical application, probe model options can be incorporated into the model selection process. More in-depth understanding of closed-form model characteristics for sample probing purposes, and the formulation and evaluation of other probe models can be important future work directions. Overall, the fact that we observe equivalent (2) or better (9) h-scores in 11 out of 12 sample probing experiments indicates the versatility of the approach in terms of compatibility with various closed-form probe models.\nComparison to other generative GZSL approaches. Performance comparisons across independent experiment results can be misleading due to differences in formulation-agnostic implementation and model selection details. Nevertheless, an overall comparison can be found in Appendix A. and probe-validation classes, respectively. We observe that using either one during the evaluation of the sample probing ZSL model, brings its own characteristic results (Table). On all datasets, using zsl-loss increases the seen accuracy while using gzsl-loss increases the unseen accuracy. We choose among these two options using our same hyper-parameter tuning policy, on the validation set. Effect of sample probing loss weight. Figure shows the validation and test set h-score values as a function of sample probing loss weight. In the test set results, we observe an overall increasing performance trend with larger loss weights, up to the weight 6, highlighting the contribution of sample probing. The optimal weight with respect to the validation and the test sets, however, differs. This observation is an example for the difficulty of tuning the ZSL model based on validation set. We set the loss weight to 5 following our hyper-parameter tuning policy, which yields almost 0.5 lower than the maximum test-set score observed for this single hyper-parameter.\nQuantitative analysis of sample quality. We quantitatively evaluate the sample quality using Fréchet (Wasserstein-2) distance, which is also used in the FID metric for evaluating GAN models. In Table, we provide a comparison for TF-VAEGAN and our approach for respective mean per-class Fréchet distances between real and synthetic samples (200 synthetic samples per class) of unseen classes on three datasets. The results show that sample probing helps generator to generate more realistic samples compared to TF-VAEGAN. We further investigate the qualitative analysis of the sample quality via t-SNE visualizations in Appendix B.\nTable 1: Evaluation of sample probing with multiple generative GZSL models on four bench_x0002_mark datasets.

Additionally, they find that two of the top three factors users reported for not reading these documents were that they are perceived as too long (`information overload') and too complicated (`difficult to understand'). This can be seen in Table TABREF3 , where a section of the terms of service for a popular phone app includes a 78-word paragraph that can be distilled down to a 19-word summary.\nThe European Union's BIBREF1 , the United States' BIBREF2 , and New York State's BIBREF3 show that many levels of government have recognized the need to make legal information more accessible to non-legal communities. Additionally, due to recent social movements demanding accessible and transparent policies on the use of personal data on the internet BIBREF4 , multiple online communities have formed that are dedicated to manually annotating various unilateral contracts.\nWe propose the task of the automatic summarization of legal documents in plain English for a non-legal audience. We hope that such a technological advancement would enable a greater number of people to enter into everyday contracts with a better understanding of what they are agreeing to. Automatic summarization is often used to reduce information overload, especially in the news domain BIBREF5 . Summarization has been largely missing in the legal genre, with notable exceptions of judicial judgments BIBREF6 , BIBREF7 and case reports BIBREF8 , as well as information extraction on patents BIBREF9 , BIBREF10 . While some companies have conducted proprietary research in the summarization of contracts, this information sits behind a large pay-wall and is geared toward law professionals rather than the general public.\nIn an attempt to motivate advancement in this area, we have collected 446 sets of contract sections and corresponding reference summaries which can be used as a test set for such a task. We have compiled these sets from two websites dedicated to explaining complicated legal documents in plain English.\nRather than attempt to summarize an entire document, these sources summarize each document at the section level. In this way, the reader can reference the more detailed text if need be. The summaries in this dataset are reviewed for quality by the first author, who has 3 years of professional contract drafting experience.\nThe dataset we propose contains 446 sets of parallel text. We show the level of abstraction through the number of novel words in the reference summaries, which is significantly higher than the abstractive single-document summaries created for the shared tasks of the Document Understanding Conference (DUC) in 2002 BIBREF11 , a standard dataset used for single document news summarization. Additionally, we utilize several common readability metrics to show that there is an average of a 6 year reading level difference between the original documents and the reference summaries in our legal dataset.\nIn initial experimentation using this dataset, we employ popular unsupervised extractive summarization models such as TextRank BIBREF12 and Greedy KL BIBREF13 , as well as lead baselines. We show that such methods do not perform well on this dataset when compared to the same methods on DUC 2002. These results highlight the fact that this is a very challenging task. As there is not currently a dataset in this domain large enough for supervised methods, we suggest the use of methods developed for simplification and/or style transfer.\nIn this paper, we begin by discussing how this task relates to the current state of text summarization and similar tasks in Section SECREF2 . We then introduce the novel dataset and provide details on the level of abstraction, compression, and readability in Section SECREF3 . Next, we provide results and analysis on the performance of extractive summarization baselines on our data in Section SECREF5 . Finally, we discuss the potential for unsupervised systems in this genre in Section SECREF6 .\nWe propose the task of the automatic summarization of legal documents in plain English for a non-legal audience.",

        "question": "Is CRWIZ already used for data collection, what are the results?",
        "answer": "Yes, CRWIZ has been used for data collection and its initial use resulted in 145 dialogues. The average time taken for the task was close to the estimate of 10 minutes, 14 dialogues (9.66%) resolved the emergency in the scenario, and these dialogues rated consistently higher in subjective and objective ratings than those which did not resolve the emergency. Qualitative results showed that participants believed that they were interacting with an automated assistant.",
        "evidence": "For the intitial data collection using the CRWIZ platform, 145 unique dialogues were collected (each dialogue consists of a conversation between two participants). All the dialogues were manually checked by one of the authors and those where the workers were clearly not partaking in the task or collaborating were removed from the dataset. The average time per assignment was 10 minutes 47 seconds, very close to our initial estimate of 10 minutes, and the task was available for 5 days in AMT. Out of the 145 dialogues, 14 (9.66%) obtained the bonus of $0.2 for resolving the emergency. We predicted that only a small portion of the participants would be able to resolve the emergency in less than 6 minutes, thus it was framed as a bonus challenge rather than a requirement to get paid. The fastest time recorded to resolve the emergency was 4 minutes 13 seconds with a mean of 5 minutes 8 seconds. Table TABREF28 shows several interaction statistics for the data collected compared to the single lab-based WoZ study BIBREF4.\nData Analysis ::: Subjective Data\nTable TABREF33 gives the results from the post-task survey. We observe, that subjective and objective task success are similar in that the dialogues that resolved the emergency were rated consistently higher than the rest.\nMann-Whitney-U one-tailed tests show that the scores of the Emergency Resolved Dialogues for Q1 and Q2 were significantly higher than the scores of the Emergency Not Resolved Dialogues at the 95% confidence level (Q1: $U = 1654.5$, $p < 0.0001$; Q2: $U = 2195$, $p = 0.009$, both $p < 0.05$). This indicates that effective collaboration and information ease are key to task completion in this setting.\nRegarding the qualitative data, one of the objectives of the Wizard-of-Oz technique was to make the participant believe that they are interacting with an automated agent and the qualitative feedback seemed to reflect this: “The AI in the game was not helpful at all [...]” or “I was talking to Fred a bot assistant, I had no other partner in the game“.\nData Analysis ::: Single vs Multiple Wizards\nIn Table TABREF28, we compare various metrics from the dialogues collected with crowdsourcing with the dialogues previously collected in a lab environment for a similar task. Most figures are comparable, except the number of emergency assistant turns (and consequently the total number of turns). To further understand these differences, we have first grouped the dialogue acts in four different broader types: Updates, Actions, Interactions and Requests, and computed the relative frequency of each of these types in both data collections. In addition, Figures FIGREF29 and FIGREF30 show the distribution of the most frequent dialogue acts in the different settings. It is visible that in the lab setting where the interaction was face-to-face with a robot, the Wizard used more Interaction dialogue acts (Table TABREF32). These were often used in context where the Wizard needed to hold the turn while looking for the appropriate prompt or waiting for the robot to arrive at the specified goal in the environment. On the other hand, in the crowdsourced data collection utterances, the situation updates were a more common choice while the assistant was waiting for the robot to travel to the specified goal in the environment.\nPerhaps not surprisingly, the data shows a medium strong positive correlation between task success and the number of Action type dialogue acts the Wizard performs, triggering events in the world leading to success ($R=0.475$). There is also a positive correlation between task success and the number of Request dialogue acts requesting confirmation before actions ($R=0.421$), e.g., “Which robot do you want to send?”. As Table 3 shows, these are relatively rare but perhaps reflect a level of collaboration needed to further the task to completion. Table TABREF40 shows one of the dialogues collected where the Emergency Assistant continuously engaged with the Operator through these types of dialogue acts.\nThe task success rate was also very different between the two set-ups. In experiments reported in BIBREF4, 96% of the dialogues led to the extinction of the fire whereas in the crowdsourcing setting only 9.66% achieved the same goal. In the crowdsourced setting, the robots were slower moving at realistic speeds unlike the lab setting. A higher bonus and more time for the task might lead to a higher task success rate.\nData Analysis ::: Limitations\nIt is important to consider the number of available participants ready and willing to perform the task at any one time. This type of crowdsourcing requires two participants to connect within a few minutes of each other to be partnered together. As mentioned above, there were some issues with participants not collaborating and these dialogues had to be discarded as they were not of use.\nFor the intitial data collection using the CRWIZ platform, 145 unique dialogues were collected (each dialogue consists of a conversation between two participants). \nThe average time per assignment was 10 minutes 47 seconds, very close to our initial estimate of 10 minutes, and the task was available for 5 days in AMT.

        "evidence": "Disclaimer: Due to the nature of the paper, some examples contain highly offensive language and hate speech. They don't reflect the views of the authors in any way, and the point of the paper is to help fight such speech. Much recent interest has focused on the detection of offensive language and hate speech in online social media. Such language is often associated with undesirable online behaviors such as trolling, cyberbullying, online extremism, political polarization, and propaganda. Thus, offensive language detection is instrumental for a variety of application such as: quantifying polarization BIBREF0, BIBREF1, trolls and propaganda account detection BIBREF2, detecting the likelihood of hate crimes BIBREF3; and predicting conflict BIBREF4. In this paper, we describe our methodology for building a large dataset of Arabic offensive tweets. Given that roughly 1-2% of all Arabic tweets are offensive BIBREF5, targeted annotation is essential for efficiently building a large dataset. Since our methodology does not use a seed list of offensive words, it is not biased by topic, target, or dialect. Using our methodology, we tagged 10,000 Arabic tweet dataset for offensiveness, where offensive tweets account for roughly 19% of the tweets. Further, we labeled tweets as vulgar or hate speech. To date, this is the largest available dataset, which we plan to make publicly available along with annotation guidelines. We use this dataset to characterize Arabic offensive language to ascertain the topics, dialects, and users' gender that are most associated with the use of offensive language. Though we suspect that there are common features that span different languages and cultures, some characteristics of Arabic offensive language is language and culture specific. Thus, we conduct a thorough analysis of how Arabic users use offensive language. Next, we use the dataset to train strong Arabic offensive language classifiers using state-of-the-art representations and classification techniques. Specifically, we experiment with static and contextualized embeddings for representation along with a variety of classifiers such as a deep neural network classifier and Support Vector Machine (SVM).\nThe contributions of this paper are as follows:\nWe built the largest Arabic offensive language dataset to date that includes special tags for vulgar language and hate speech. We describe the methodology for building it along with annotation guidelines.\nWe performed thorough analysis of the dataset and described the peculiarities of Arabic offensive language.\nWe experimented with Support Vector Machine classifiers on character and word ngrams classification techniques to provide strong results on Arabic offensive language classification.\nUsing our methodology, we tagged 10,000 Arabic tweet dataset for offensiveness, where offensive tweets account for roughly 19% of the tweets.",

        "evidence": "Stylometry is defined as, \"the statistical analysis of variations in literary style between one writer or genre and another\". It is a centuries-old practice, dating back the early Renaissance. It is most often used to attribute authorship to disputed or anonymous documents. Stylometry techniques have also successfully been applied to other, non-linguistic fields, such as paintings and music. The main principles of stylometry were compiled and laid out by the philosopher Wincenty Lutosławski in 1890 in his work \"Principes de stylométrie\" BIBREF0 .\nToday, there are millions of users with accounts and profiles on many different social media and networking sites. It is not uncommon for users to have multiple accounts on different social media and networking sites. With so many networking, emailing, and photo sharing sites on the Web, a user often accumulates an abundance of account profiles. There is an increasing focus from the academic and business worlds on aggregating user information across different sites, allowing for the development of more complete user profiles. There currently exist several businesses that focus on this task BIBREF1 , BIBREF2 , BIBREF3 . These businesses use the aggregate profiles for advertising, background checks or customer service related tasks. Moreover, profile matching across social networks, can assist the growing field of social media rumor detection BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , since many malicious rumors are spread on different social media platforms by the same people, using different accounts and usernames.\nMotivated by traditional stylometry and the growing interest in matching user accounts across Internet services, we created models for Digital Stylometry, which fuses traditional stylometry techniques with big-data driven social informatics methods used commonly in analyzing social networks. Our models use linguistic and temporal activity patterns of users on different accounts to match accounts belonging to the same person. We evaluated our models on $11,224$ accounts belonging to $5,612$ distinct users on two of the largest social media networks, Twitter and Facebook. The only information that was used in our models were the time and the linguistic content of posts by the users. We intentionally did not use any other information, especially the potentially personally identifiable information that was explicitly provided by the user, such as the screen name, birthday or location. This is in accordance with traditional stylometry techniques, since people could misstate, omit, or lie about this information. Also, we wanted to show that there are implicit clues about the identities of users in the content (language) and context (time) of the users' interactions with social networks that can be used to link their accounts across different services.\nOther than the obvious technical goal, the purpose of this paper is to shed light on the relative ease with which seemingly innocuous information can be used to track users across social networks, even when signing up on different services using completely different account and profile information (such as name and birthday). This paper is as much of a technical contribution, as it is a warning to users who increasingly share a large part of their private lives on these services.\nThe rest of this paper is structured as follows. In the next sections we will review related work on linking profiles, followed by a description of our data collection and annotation efforts. After that, we discuss the linguistic, temporal and combined temporal-linguistic models developed for linking user profiles. Finally, we discuss and summarize our findings and contributions and discuss possible paths for future work.\nStylometry is defined as, ”the statistical analysis of variations in literary style between one writer or genre and another”.",

        "answer": "The causes of the poor performance of the NART model.",
        "evidence": "Neural machine translation has attracted much attention in recent years BIBREF0, BIBREF1, BIBREF2, BIBREF3. Given a sentence $x=(x_1, \\dots ,x_{T_x})$ from the source language, the straight-forward way for translation is to generate the target words $y=(y_1, \\dots , y_{T_y})$ one by one from left to right. This is also known as the AutoRegressive Translation (ART) models, in which the joint probability is decomposed into a chain of conditional probabilities:\nWhile the ART models have achieved great success in terms of translation quality, the time consumption during inference is still far away from satisfactory. During training, the predictions at different positions can be estimated in parallel since the ground truth pair $(x,y)$ is exposed to the model. However, during inference, the model has to generate tokens sequentially as $y_{<t}$ must be inferred on the fly. Such autoregressive behavior becomes the bottleneck of the computational time BIBREF4.\nIn order to speed up the inference process, a line of works begin to develop non-autoregressive translation models. These models break the autoregressive dependency by decomposing the joint probability with\nThe lost of autoregressive dependency largely hurt the consistency of the output sentences, increase the difficulty in the learning process and thus lead to a low quality translation. Previous works mainly focus on adding different components into the NART model to improve the expressiveness of the network structure to overcome the loss of autoregressive dependency BIBREF5, BIBREF6, BIBREF7. However, the computational overhead of new components will hurt the inference speed, contradicting with the goal of the NART models: to parallelize and speed up neural machine translation models.\nTo tackle this, we proposed a novel hint-based method for NART model training. We first investigate the causes of the poor performance of the NART model. Comparing with the ART model, we find that: (1) the positions where the NART model outputs incoherent tokens will have very high hidden states similarity; (2) the attention distributions of the NART model are more ambiguous than those of ART model. Therefore, we design two kinds of hints from the hidden states and attention distributions of the ART model to help the training of the NART model. The experimental results show that our model achieves significant improvement over the NART baseline models and is even comparable to a strong ART baseline in BIBREF4.\nWe first investigate the causes of the poor performance of the NART model.

This approximation, while retaining the sparsity constraint, avoids the complication of dealing with the variational treatment of the stick breaking process frequent in Bayesian non-parametric models. The second variant, which we shall denote Structured Variational AutoEncoder (SVAE) AUD, is based upon the work of BIBREF4 and embeds the HMM model into the Variational AutoEncoder framework BIBREF9 . A very similar version of the SVAE for AUD was developed independently and presented in BIBREF5 . The main noteworthy difference between BIBREF5 and our model is that we consider a fully Bayesian version of the HMM embedded in the VAE; and the posterior distribution and the VAE parameters are trained jointly using the Stochastic Variational Bayes BIBREF4 , BIBREF10 . For both variants, the prior over the HMM parameters were set to the conjugate of the likelihood density: Normal-Gamma prior for the mean and variance of the Gaussian components, symmetric Dirichlet prior over the HMM's state mixture's weights and symmetric Dirichlet prior over the acoustic units' weights.

        "evidence": "* Equal contribution. Listing order is random.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma. More concretely, consider the English sentence: The bulls are running in Pamplona. A lemmatizer will seek to map each word to a form you may find in a dictionary—for instance, mapping running to run. This linguistic normalization is important in several downstream NLP applications, especially for highly inflected languages. Lemmatization has previously been shown to improve recall for information retrieval BIBREF0 , BIBREF1 , to aid machine translation BIBREF2 , BIBREF3 and is a core part of modern parsing systems BIBREF4 , BIBREF5 .\nHowever, the task is quite nuanced as the proper choice of the lemma is context dependent. For instance, in the sentence A running of the bulls took place in Pamplona, the word running is its own lemma, since, here, running is a noun rather than an inflected verb. Several counter-examples exist to this trend, as discussed in depth in haspelmath2013understanding. Thus, a good lemmatizer must make use of some representation of each word's sentential context. The research question in this work is, then, how do we design a lemmatization model that best extracts the morpho-syntax from the sentential context?\nRecent work BIBREF7 has presented a system that directly summarizes the sentential context using a recurrent neural network to decide how to lemmatize. As N18-1126's system currently achieves state-of-the-art results, it must implicitly learn a contextual representation that encodes the necessary morpho-syntax, as such knowledge is requisite for the task. We contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize. Indeed, to this end, we introduce a joint model for the introduction of morphology into a neural lemmatizer. A key feature of our model is its simplicity: Our contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model. However, despite the model's simplicity, it still achieves a significant improvement over the state of the art on our target task: lemmatization.\nExperimentally, our contributions are threefold. First, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora BIBREF8 . Second, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization. Finally, we provide a detailed error analysis indicating when and why morphological analysis helps lemmatization. We offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.\nOur system and pre-trained models on all languages in the latest version of the UD corpora are released at https://sigmorphon.github.io/sharedtasks/2019/task2/.\nWe contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize.

In NL navigation studies, the representation of the world may be provided via visual sensors BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4 or as a symbolic world representation. This work focuses on navigation based on a symbolic world representation (referred to as a map).\nPrevious datasets for NL navigation based on a symbolic world representation, HCRC BIBREF5, BIBREF6, BIBREF7 and SAIL BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15 present relatively simple worlds, with a small fixed set of entities known to the navigator in advance. Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes. Using Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers. This task raises several challenges. First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state.",

        "question": "Summarise the history of the origin of the Kievan Rus' name",
        "evidence": "Prior to the emergence of Kievan Rus' in the 9th century, most of the area north of the Black Sea, which roughly overlaps with modern-day Ukraine and Belarus, was primarily populated by eastern Slavic tribes. In the northern region around Novgorod were the Ilmen Slavs and neighboring Krivichi, who occupied territories surrounding the headwaters of the West Dvina, Dnieper and Volga rivers. To their north, in the Ladoga and Karelia regions, were the Finnic Chud tribe. In the south, in the area around Kiev, were the Poliane, a group of Slavicized tribes with Iranian origins, the Drevliane to the west of the Dnieper, and the Severiane to the east. To their north and east were the Vyatichi, and to their south was forested land settled by Slav farmers, giving way to steppe lands populated by nomadic herdsmen.\n\nThere was once controversy over whether the Rus' were Varangians or Slavs, however, more recently scholarly attention has focused more on debating how quickly an ancestrally Norse people assimilated into Slavic culture. This uncertainty is due largely to a paucity of contemporary sources. Attempts to address this question instead rely on archaeological evidence, the accounts of foreign observers, and legends and literature from centuries later. To some extent, the controversy is related to the foundation myths of modern states in the region. This often unfruitful debate over origins has periodically devolved into competing nationalist narratives of dubious scholarly value being promoted directly by various government bodies, in a number of states. This was seen in the Stalinist period, when Soviet historiography sought to distance the Rus' from any connection to Germanic tribes, in an effort to dispel Nazi propaganda claiming the Russian state owed its existence and origins to the supposedly racially superior Norse tribes. More recently, in the context of resurgent nationalism in post-Soviet states, Anglophone scholarship has analyzed renewed efforts to use this debate to create ethno-nationalist foundation stories, with governments sometimes directly involved in the project. Conferences and publications questioning the Norse origins of the Rus' have been supported directly by state policy in some cases, and the resultant foundation myths have been included in some school textbooks in Russia.\n\nWhile Varangians were Norse traders and Vikings, some Russian and Ukrainian nationalist historians argue that the Rus' were themselves Slavs (see Anti-Normanism). Normanist theories focus on the earliest written source for the East Slavs, the Primary Chronicle, which was produced in the 12th century. Nationalist accounts on the other hand have suggested that the Rus' were present before the arrival of the Varangians, noting that only a handful of Scandinavian words can be found in Russian and that Scandinavian names in the early chronicles were soon replaced by Slavic names.\n\nNevertheless, the close connection between the Rus' and the Norse is confirmed both by extensive Scandinavian settlements in Belarus, Russia, and Ukraine and by Slavic influences in the Swedish language.Though the debate over the origin of the Rus' remains politically charged, there is broad agreement that if the proto-Rus' were indeed originally Norse, they were quickly nativized, adopting Slavic languages and other cultural practices. This position, roughly representing a scholarly consensus (at least outside of nationalist historiography), was summarized by the historian, F. Donald Logan, \"in 839, the Rus were Swedes; in 1043 the Rus were Slavs\". Recent scholarship has attempted to move past the narrow and politicized debate on origins, to focus on how and why assimilation took place so quickly. Some modern DNA testing also points to Viking origins, not only of some of the early Rus' princely family and/or their retinues but also links to possible brethren from neighboring countries like Sviatopolk I of Kiev.\n\nAhmad ibn Fadlan, an Arab traveler during the 10th century, provided one of the earliest written descriptions of the Rus': \"They are as tall as a date palm, blond and ruddy, so that they do not need to wear a tunic nor a cloak; rather the men among them wear garments that only cover half of his body and leaves one of his hands free.\" Liutprand of Cremona, who was twice an envoy to the Byzantine court (949 and 968), identifies the \"Russi\" with the Norse (\"the Russi, whom we call Norsemen by another name\") but explains the name as a Greek term referring to their physical traits (\"A certain people made up of a part of the Norse, whom the Greeks call [...] the Russi on account of their physical features, we designate as Norsemen because of the location of their origin.\"). Leo the Deacon, a 10th-century Byzantine historian and chronicler, refers to the Rus' as \"Scythians\" and notes that they tended to adopt Greek rituals and customs. But 'Scythians' in Greek parlance is used predominantly as a generic term for nomads.",

        "evidence": "Knowledge and/or data is often modeled in a structure, such as indexes, tables, key-value pairs, or triplets. These data, by their nature (e.g., raw data or long time-series data), are not easily usable by humans; outlining their crucial need to be synthesized. Recently, numerous works have focused on leveraging structured data in various applications, such as question answering BIBREF0, BIBREF1 or table retrieval BIBREF2, BIBREF3. One emerging research field consists in transcribing data-structures into natural language in order to ease their understandablity and their usablity. This field is referred to as “data-to-text\" BIBREF4 and has its place in several application domains (such as journalism BIBREF5 or medical diagnosis BIBREF6) or wide-audience applications (such as financial BIBREF7 and weather reports BIBREF8, or sport broadcasting BIBREF9, BIBREF10). As an example, Figure FIGREF1 shows a data-structure containing statistics on NBA basketball games, paired with its corresponding journalistic description.\nDesigning data-to-text models gives rise to two main challenges: 1) understanding structured data and 2) generating associated descriptions. Recent data-to-text models BIBREF11, BIBREF12, BIBREF13, BIBREF10 mostly rely on an encoder-decoder architecture BIBREF14 in which the data-structure is first encoded sequentially into a fixed-size vectorial representation by an encoder. Then, a decoder generates words conditioned on this representation. With the introduction of the attention mechanism BIBREF15 on one hand, which computes a context focused on important elements from the input at each decoding step and, on the other hand, the copy mechanism BIBREF16, BIBREF17 to deal with unknown or rare words, these systems produce fluent and domain comprehensive texts. For instance, Roberti et al. BIBREF18 train a character-wise encoder-decoder to generate descriptions of restaurants based on their attributes, while Puduppully et al. BIBREF12 design a more complex two-step decoder: they first generate a plan of elements to be mentioned, and then condition text generation on this plan. Although previous work yield overall good results, we identify two important caveats, that hinder precision (i.e. factual mentions) in the descriptions:\n\nLinearization of the data-structure. In practice, most works focus on introducing innovating decoding modules, and still represent data as a unique sequence of elements to be encoded. For example, the table from Figure FIGREF1 would be linearized to [(Hawks, H/V, H), ..., (Magic, H/V, V), ...], effectively leading to losing distinction between rows, and therefore entities. To the best of our knowledge, only Liu et al. BIBREF19, BIBREF11 propose encoders constrained by the structure but these approaches are designed for single-entity structures.\nArbitrary ordering of unordered collections in recurrent networks (RNN). Most data-to-text systems use RNNs as encoders (such as GRUs or LSTMs), these architectures have however some limitations. Indeed, they require in practice their input to be fed sequentially. This way of encoding unordered sequences (i.e. collections of entities) implicitly assumes an arbitrary order within the collection which, as demonstrated by Vinyals et al. BIBREF20, significantly impacts the learning performance.\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured. Our contribution focuses on the encoding of the data-structure, thus the decoder is chosen to be a classical module as used in BIBREF12, BIBREF10. Our contribution is threefold:\n\nWe model the general structure of the data using a two-level architecture, first encoding all entities on the basis of their elements, then encoding the data structure on the basis of its entities;\nWe introduce the Transformer encoder BIBREF21 in data-to-text models to ensure robust encoding of each element/entities in comparison to all others, no matter their initial positioning;\nWe integrate a hierarchical attention mechanism to compute the hierarchical context fed into the decoder.\nWe report experiments on the RotoWire benchmark BIBREF10 which contains around $5K$ statistical tables of NBA basketball games paired with human-written descriptions. Our model is compared to several state-of-the-art models. Results show that the proposed architecture outperforms previous models on BLEU score and is generally better on qualitative metrics.\nIn the following, we first present a state-of-the art of data-to-text literature (Section 2), and then describe our proposed hierarchical data encoder (Section 3). The evaluation protocol is presented in Section 4, followed by the results (Section 5). Section 6 concludes the paper and presents perspectives.\n\nTo address these shortcomings, we propose a new structured-data encoder assuming that structures should be hierarchically captured.",

        "answer": "How to handle the rare words which do not appear in the short lists of the vocabulary.",
        "evidence": "An NMT system consists of an encoder which automatically learns the characteristics of a source sentence into fix-length context vectors and a decoder that recursively combines the produced context vectors with the previous target word to generate the most probable word from a target vocabulary.\nMore specifically, a bidirectional recurrent encoder reads every words INLINEFORM0 of a source sentence INLINEFORM1 and encodes a representation INLINEFORM2 of the sentence into a fixed-length vector INLINEFORM3 concatinated from those of the forward and backward directions: INLINEFORM4 \nHere INLINEFORM0 is the one-hot vector of the word INLINEFORM1 and INLINEFORM2 is the word embedding matrix which is shared across the source words. INLINEFORM3 is the recurrent unit computing the current hidden state of the encoder based on the previous hidden state. INLINEFORM4 is then called an annotation vector, which encodes the source sentence up to the time INLINEFORM5 from both forward and backward directions. Recurrent units in NMT can be a simple recurrent neural network unit (RNN), a Long Short-Term Memory unit (LSTM) BIBREF3 or a Gated Recurrent Unit (GRU) BIBREF4 \nSimilar to the encoder, the recurrent decoder generates one target word INLINEFORM0 to form a translated target sentence INLINEFORM1 in the end. At the time INLINEFORM2 , it takes the previous hidden state of the decoder INLINEFORM3 , the previous embedded word representation INLINEFORM4 and a time-specific context vector INLINEFORM5 as inputs to calculate the current hidden state INLINEFORM6 : INLINEFORM7 \nAgain, INLINEFORM0 is the recurrent activation function of the decoder and INLINEFORM1 is the shared word embedding matrix of the target sentences. The context vector INLINEFORM2 is calculated based on the annotation vectors from the encoder. Before feeding the annotation vectors into the decoder, an attention mechanism is set up in between, in order to choose which annotation vectors should contribute to the predicting decision of the next target word. Intuitively, a relevance between the previous target word and the annotation vectors can be used to form some attention scenario. There exists several ways to calculate the relevance as shown in BIBREF5 , but what we describe here follows the proposed method of BIBREF2 DISPLAYFORM0 \nIn BIBREF2 , this attention mechanism, originally called alignment model, has been employed as a simple feedforward network with the first layer is a learnable layer via INLINEFORM0 , INLINEFORM1 and INLINEFORM2 . The relevance scores INLINEFORM3 are then normalized into attention weights INLINEFORM4 and the context vector INLINEFORM5 is calculated as the weighted sum of all annotation vectors INLINEFORM6 . Depending on how much attention the target word at time INLINEFORM7 put on the source states INLINEFORM8 , a soft alignment is learned. By being employed this way, word alignment is not a latent variable but a parametrized function, making the alignment model differentiable. Thus, it could be trained together with the whole architecture using backpropagation.\nOne of the most severe problems of NMT is handling of the rare words, which are not in the short lists of the vocabularies, i.e. out-of-vocabulary (OOV) words, or do not appear in the training set at all. In BIBREF6 , the rare target words are copied from their aligned source words after the translation. This heuristic works well with OOV words and named entities but unable to translate unseen words. In BIBREF7 , their proposed NMT models have been shown to not only be effective on reducing vocabulary sizes but also have the ability to generate unseen words. This is achieved by segmenting the rare words into subword units and translating them. The state-of-the-art translation systems essentially employ subword NMT BIBREF7 .\nOne of the most severe problems of NMT is handling of the rare words, which are not in the short lists of the vocabularies, i.e. out-of-vocabulary (OOV) words, or do not appear in the training set at all.",

It is also easy to divide the data into training and test sets by using Bible verse numbers, which allows us to control for semantic similarity between languages in a way that would have been difficult in a corpus that is not multi-parallel. Altogether we have 1,303 translations in 990 languages that we can use for our purposes. These were chosen so that the model alphabet size is below 1000 symbols, which was satisfied by choosing only translations in Latin, Cyrillic or Greek script.\nCertainly, there are disadvantages as well, such as the limited size (roughly 500 million tokens in total, with most languages having only one translation of the New Testament each, with roughly 200 thousand tokens), the narrow domain and the high overlap of named entities. The latter can lead to some unexpected effects when using nonsensical language vectors, as the model will then generate a sequence of random names.\nThe corpus deviates in some ways from an ideal multi-parallel corpus.

        "answer": "A loss function with a built-in threshold.",
        "evidence": "At a high level, as shown in Figure FIGREF4 , a product search engine works as follows: a customer issues a query, which is passed to a lexical matching engine (typically an inverted index BIBREF0 , BIBREF1 ) to retrieve all products that contain words in the query, producing a match set. The match set passes through stages of ranking, wherein top results from the previous stage are re-ranked before the most relevant items are finally displayed. It is imperative that the match set contain a relevant and diverse set of products that match the customer intent in order for the subsequent rankers to succeed. However, inverted index-based lexical matching falls short in several key aspects:\nIn this paper, we address the question: Given rich customer behavior data, can we train a deep learning model to retrieve matching products in response to a query? Intuitively, there is reason to believe that customer behavior logs contain semantic information; customers who are intent on purchasing a product circumvent the limitations of lexical matching by query reformulation or by deeper exploration of the search results. The challenge is the sheer magnitude of the data as well as the presence of noise, a challenge that modern deep learning techniques address very effectively.\nProduct search is different from web search as the queries tend to be shorter and the positive signals (purchases) are sparser than clicks. Models based on conversion rates or click-through-rates may incorrectly favor accessories (like a phone cover) over the main product (like a cell phone). This is further complicated by shoppers maintaining multiple intents during a single search session: a customer may be looking for a specific television model while also looking for accessories for this item at the lowest price and browsing additional products to qualify for free shipping. A product search engine should reduce the effort needed from a customer with a specific mission (narrow queries) while allowing shoppers to explore when they are looking for inspiration (broad queries).\nAs mentioned, product search typically operates in two stages: matching and ranking. Products that contain words in the query ( INLINEFORM0 ) are the primary candidates. Products that have prior behavioral associations (products bought or clicked after issuing a query INLINEFORM1 ) are also included in the candidate set. The ranking step takes these candidates and orders them using a machine-learned rank function to optimize for customer satisfaction and business metrics.\nWe present a neural network trained with large amounts of purchase and click signals to complement a lexical search engine in ad hoc product retrieval. Our first contribution is a loss function with a built-in threshold to differentiate between random negative, impressed but not purchased, and purchased items. Our second contribution is the empirical result that recommends average pooling in combination with INLINEFORM0 -grams that capture short-range linguistic patterns instead of more complex architectures. Third, we show the effectiveness of consistent token hashing in Siamese networks for zero-shot learning and handling out of vocabulary tokens.\nIn Section SECREF2 , we highlight related work. In Section SECREF3 , we describe our model architecture, loss functions, and tokenization techniques including our approach for unseen words. We then introduce the readers to the data and our input representations for queries and products in Section SECREF4 . Section SECREF5 presents the evaluation metrics and our results. We provide implementation details and optimizations to efficiently train the model with large amounts of data in Section SECREF6 . Finally, we conclude in Section SECREF7 with a discussion of future work.\nOur first contribution is a loss function with a built-in threshold to differentiate between random negative, impressed but not purchased, and purchased items.",

        "evidence": "We compare our two exploration strategies to the following baselines and ablations:\nKG-A2C This is the exact same method presented in BIBREF6 with no modifications.\nA2C Represents the same approach as KG-A2C but with all the knowledge graph components removed. The state representation is text only encoded using recurrent networks.\nA2C-chained Is a variation on KG-A2C-chained where we use our policy chaining approach with the A2C method to train the agent instead of KG-A2C.\nA2C-Explore Uses A2C in addition to the exploration strategy seen in KG-A2C-Explore. The cell representations here are defined in terms of the recurrent network based encoding of the textual observation.\nFigure FIGREF10 shows that agents utilizing knowledge-graphs in addition to either enhanced exploration method far outperform the baseline A2C and KG-A2C. KG-A2C-chained and KG-A2C-Explore both pass the bottleneck of a score of 40, whereas A2C-Explore gets to the bottleneck but cannot surpass it.\nThere are a couple of key insights that can be drawn from these results The first is that the knowledge graph appears to be critical; it is theorized to help with partial observability. However the knowledge graph representation isn't sufficient in that the knowledge graph representation without enhanced exploration methods cannot surpass the bottleneck. A2C-chained—which explores without a knowledge graph—fails to even outperform the baseline A2C. We hypothesize that this is due to the knowledge graph aiding implicitly in the sample efficiency of bottleneck detection and subsequent exploration. That is, exploring after backtracking from a potentially detected bottleneck is much more efficient in the knowledge graph based agent.\nThe Go-Explore based exploration algorithm sees less of a difference between agents. A2C-Explore converges more quickly, but to a lower reward trajectory that fails to pass the bottleneck, whereas KG-A2C-Explore takes longer to reach a similar reward but consistently makes it through the bottleneck. The knowledge graph cell representation appears to thus be a better indication of what a promising state is as opposed to just the textual observation.\nComparing the advanced exploration methods when using the knowledge graph, we see that both agents successfully pass the bottleneck corresponding to entering the cellar and lighting the lamp and reach comparable scores within a margin of error. KG-A2C-chained is significantly more sample efficient and converges faster. We can infer that chaining policies by explicitly detecting bottlenecks lets us pass it more quickly than attempting to find promising cell representations with Go-Explore. This form of chained exploration with backtracking is particularly suited to sequential decision making problems that can be represented as acyclic directed graphs as in Figure FIGREF1.\nKG-A2C-chained is significantly more sample efficient and converges faster.

        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources.

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task.",

        "answer": "It is a topic model that can effectively and efficiently leverage arbitrary document and word meta information encoded in binary form.",
        "evidence": "With the rapid growth of the internet, huge amounts of text data are generated in social networks, online shopping and news websites, etc. These data create demand for powerful and efficient text analysis techniques. Probabilistic topic models such as Latent Dirichlet Allocation (LDA) BIBREF0 are popular approaches for this task, by discovering latent topics from text collections. Many conventional topic models discover topics purely based on the word-occurrences, ignoring the meta information (a.k.a., side information) associated with the content. In contrast, when we humans read text it is natural to leverage meta information to improve our comprehension, which includes categories, authors, timestamps, the semantic meanings of the words, etc. Therefore, topic models capable of using meta information should yield improved modelling accuracy and topic quality.\nIn practice, various kinds of meta information are available at the document level and the word level in many corpora. At the document level, labels of documents can be used to guide topic learning so that more meaningful topics can be discovered. Moreover, it is highly likely that documents with common labels discuss similar topics, which could further result in similar topic distributions. For example, if we use authors as labels for scientific papers, the topics of the papers published by the same researcher can be closely related.\nAt the word level, different semantic/syntactic features are also accessible. For example, there are features regarding word relationships, such as synonyms obtained from WordNet BIBREF1 , word co-occurrence patterns obtained from a large corpus, and linked concepts from knowledge graphs. It is preferable that words having similar meaning but different morphological forms, like “dog” and “puppy”, are assigned to the same topic, even if they barely co-occur in the modelled corpus. Recently, word embeddings generated by GloVe BIBREF2 and word2vec BIBREF3 , have attracted a lot of attention in natural language processing and related fields. It has been shown that the word embeddings can capture both the semantic and syntactic features of words so that similar words are close to each other in the embedding space. It seems reasonable to expect that these word embedding will improve topic modelling BIBREF4 , BIBREF5 .\nConventional topic models can suffer from a large performance degradation over short texts (e.g., tweets and news headlines) because of insufficient word co-occurrence information. In such cases, meta information of documents and words can play an important role in analysing short texts by compensating the lost information in word co-occurrences. At the document level, for example, tweets are usually associated with hashtags, users, locations, and timestamps, which can be used to alleviate the data sparsity problem. At the word level, word semantic similarity and embeddings obtained or trained on large external corpus (e.g., Google News or Wikipedia) have been proven useful in learning meaningful topics from short texts BIBREF6 , BIBREF7 .\nThe benefit of using document and word meta information separately is shown in several models such as BIBREF8 , BIBREF9 , BIBREF5 . However, in existing models this is usually not efficient enough due to non-conjugacy and/or complex model structures. Moreover, only one kind of meta information (either at document level or at word level) is used in most existing models. In this paper, we propose MetaLDA, a topic model that can effectively and efficiently leverage arbitrary document and word meta information encoded in binary form. Specifically, the labels of a document in MetaLDA are incorporated in the prior of the per-document topic distributions. If two documents have similar labels, their topic distributions should be generated with similar Dirichlet priors. Analogously, at the word level, the features of a word are incorporated in the prior of the per-topic word distributions, which encourages words with similar features to have similar weights across topics. Therefore, both document and word meta information, if and when they are available, can be flexibly and simultaneously incorporated using MetaLDA. MetaLDA has the following key properties:\nWe conduct extensive experiments with several real datasets including regular and short texts in various domains. The experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.\nIn this paper, we propose MetaLDA, a topic model that can effectively and efficiently leverage arbitrary document and word meta information encoded in binary form.",

        "question": "To solve these problems, what does the author suggest?",
        "answer": "To enhance entity pages and reduces delay while keeping its pages authoritative.",
        "evidence": "Wikipedia is the largest source of open and collaboratively curated knowledge in the world. Introduced in 2001, it has evolved into a reference work with around 5m pages for the English Wikipedia alone. In addition, entities and event pages are updated quickly via collaborative editing and all edits are encouraged to include source citations, creating a knowledge base which aims at being both timely as well as authoritative. As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page. However, not all information sources are equal. The online presence of major news outlets is an authoritative source due to active editorial control and their articles are also a timely container of facts. In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them). However, such an approach lacks in (a) reproducibility since rankings vary with time with obvious bias to recent news (b) maintainability since document acquisition for each entity has to be periodically performed. To this effect, our news suggestion considers a news article as input, and determines if it is valuable for Wikipedia. Specifically, given an input news article INLINEFORM0 and a state of Wikipedia, the news suggestion problem identifies the entities mentioned in INLINEFORM1 whose entity pages can improve upon suggesting INLINEFORM2 . Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower. Third, a good recommendation should be able to identify novel news by minimizing redundancy coming from multiple news articles. Finally, addition of facts is facilitated if the recommendations are fine-grained, i.e., recommendations are made on the section level rather than the page level (placement).\nApproach and Contributions. We propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity's salience in the news article, its relative authority and the novelty of the article to the entity page. The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years. The existing news references in the entity pages along with their reference date act as our ground-truth to evaluate our approach. In summary, we make the following contributions.\nWe therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.",

        "answer": "They do not exploit any intermediate information such as gradients, and the relevance score only resembles attention scores.",
        "evidence": "Interpretability of Seq2Seq models has recently been explored mainly from two perspectives: interpreting internal representations and understanding input-output behaviors. Most of the existing work focus on the former thread, which analyzes the linguistic information embeded in the learned representations BIBREF3, BIBREF4, BIBREF10 or the hidden units BIBREF6, BIBREF5. Several researchers turn to expose systematic differences between human and NMT translations BIBREF11, BIBREF12, indicating the linguistic properties worthy of investigating. However, the learned representations may depend on the model implementation, which potentially limit the applicability of these methods to a broader range of model architectures. Accordingly, we focus on understanding the input-output behaviors, and validate on different architectures to demonstrate the universality of our findings.\nConcerning interpreting the input-output behavior, previous work generally treats Seq2Seq models as black-boxes BIBREF13, BIBREF7. For example, alvarez2017causal measure the relevance between two input-output tokens by perturbing the input sequence. However, they do not exploit any intermediate information such as gradients, and the relevance score only resembles attention scores. Recently, Jain2019AttentionIN show that attention scores are in weak correlation with the feature importance. Starting from this observation, we exploit the intermediate gradients to better estimate word importance, which consistently outperforms its attention counterpart across model architectures and language pairs.\nThe intermediate gradients have proven to be useful in interpreting deep learning models, such as NLP models BIBREF14, BIBREF15 and computer vision models BIBREF16, BIBREF9. Among all gradient-based approaches, the integrated gradients BIBREF9 is appealing since it does not need any instrumentation of the architecture and can be computed easily by calling gradient operations. In this work, we employ the IG method to interpret NMT models and reveal several interesting findings, which can potentially help debug NMT models and design better architectures for specific language pairs.\nConcerning interpreting the input-output behavior, previous work generally treats Seq2Seq models as black-boxes (Li et al., 2016; Alvarez-Melis and Jaakkola, 2017). For example, Alvarez-Melis and Jaakkola (2017) measure the relevance between two input-output tokens by perturbing the input sequence.

        "answer": "We agree that the word “object” is not clear. Following your suggestion, we modified the word “objects” by “experience transitions”.",
        "evidence": "In this paper, we consider a decentralized partially observable Markov decision process represented by a tuple G = S, U, P, r, O, N, γ . To be specific, we let s ∈ S denote the true state of the environment. At each time step, an agent i ∈ N := {1, ..., N } selects an action u i ∈ U as an element of the joint action vector u := [u 1 , • • • , u N ]. It then goes through a stochastic transition dynamic described by the probability P (s |s, u). All agents share the same reward r(s, u) discounted by a factor of γ. Each agent i is associated with a partial observation o ∈ O, according to some observation function O(s, i) : S ×N → O, and an action-observation history τ i . Concatenation of the agent-wise action-observation histories is denoted as the overall action-observation history τ .\nWe consider value-based centralized training with decentralized execution (CTDE) where agents are trained in a centralized manner and executed in parallel without access to the global state s. Under value-based CTDE, we aim to train each agent-wise utility function q i (τ i , u i ) whose greedy actions are consistent with the greedy actions from the joint action-value estimator Q jt (s, τ , u). Formally, the following decentralization condition should be satisfied:\n(1)\nTo meet this condition, VDN and QMIX impose structural constraint on the joint action-value function. To be specific, VDN expresses the joint action-value function as a linear summation of agent-wise utility functions. QMIX extends VDN by enforcing a monotonicity constraint on the joint action-value function and each agent-wise utility function. On the other hand, QTRAN uses soft regularization instead of structural constraints to satisfy the decentralization condition.\nWeighted QMIX. Another prior work, namely Weighted QMIX, implicitly considers optimism in centralized training by weighting the loss of optimal actions, but it does not separate agent-wise and environment-wise risks. proposes Centrally-Weighted QMIX (CW-QMIX) and Optimistically-Weighted QMIX (OW-QMIX) which both have a strong theoretical capability of learning the largest class of true action-value functions up to date. They use a weighted projection that allows more emphasis to be placed on better joint actions. OW-QMIX applies weights to the losses according to the sign of the TD-error for each sample: 2\nwhere α is a hyperparameter and Q target jt is the fixed target network whose parameters are updated periodically from the original unconstrained true action-value estimator Q jt . They sample (s, u, r, s ), a tuple of experience transitions from a replay buffer and u opt is the \"optimal\" action maximizing the utility functions q i (τ i , u i ) for i ∈ N . The true action-value estimator Q jt can accurately describe the true action-value using the unconstrained neural network. However, since this unconstrained network does not satisfy the decentralization condition (equation 1), we cannot extract the optimal action efficiently. On the other hand, the transformed action-value estimator Q tran has limited expressive power because of its monotonic structure but can efficiently extract optimal actions. In order for Q tran to accurately track the optimal action of Q jt , the weighting mechanism according to the sign of the TD-error assigns a higher weight for optimistic returns. Through the optimistic training, they prove that Weighted QMIX recovers the correct maximal action for any true-action value. We provide a more detailed description of other CTDE algorithms in Appendix C.\n…whose parameters are updated periodically from the original action-value estimator Z.

We made sure that our guidelines were compatible with those of OffensEval2019. The annotator carried out all annotation. Tweets were given one or more of the following four labels: offensive, vulgar, hate speech, or clean. Since the offensive label covers both vulgar and hate speech and vulgarity and hate speech are not mutually exclusive, a tweet can be just offensive or offensive and vulgar and/or hate speech. The annotation adhered to the following guidelines:\nOffensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as:\nDirect threats or incitement, ex: احرقوا> مقرات المعارضة> (“AHrqwA mqrAt AlmEArDp” – “burn the headquarters of the opposition”) and هذا المنافق يجب قتله> (“h*A AlmnAfq yjb qtlh” – “this hypocrite needs to be killed”).\nInsults and expressions of contempt, which include: Animal analogy, ex: يا كلب> (“yA klb” – “O dog”) and كل تبن> (“kl tbn” – “eat hay”).; Insult to family members, ex: يا روح أمك> (“yA rwH Amk” – “O mother's soul”); Sexually-related insults, ex: يا ديوث> (“yA dywv” – “O person without envy”); Damnation, ex: الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”); and Attacks on morals and ethics, ex: يا كاذب> (“yA kA*b” – “O liar”)\nVulgar tweets are a subset of offensive tweets and contain profanity, such as mentions of private parts or sexual-related acts or references.\nHate speech tweets, a subset of offensive tweets containing offensive language targeting group based on common characteristics such as: Race, ex: يا زنجي> (“yA znjy” – “O negro”); Ethnicity, ex. الفرس الأنجاس> (“Alfrs AlAnjAs” – “Impure Persians”); Group or party, ex: أبوك شيوعي> (“Abwk $ywEy” – “your father is communist”); and Religion, ex: دينك القذر> (“dynk Alq*r” – “your filthy religion”).\nClean tweets do not contain vulgar or offensive language. We noticed that some tweets have some offensive words, but the whole tweet should not be considered as offensive due to the intention of users. This suggests that normal string match without considering contexts will fail in some cases. Examples of such ambiguous cases include: Humor, ex: يا عدوة الفرحة ههه> (“yA Edwp AlfrHp hhh” – “O enemy of happiness hahaha”); Advice, ex: لا تقل لصاحبك يا خنزير> (“lA tql lSAHbk yA xnzyr” – “don't say to your friend: You are a pig”); Condition, ex: إذا عارضتهم يقولون يا عميل> (“A*A EArDthm yqwlwn yA Emyl” – “if you disagree with them they will say: You are an agent”); Condemnation, ex: لماذا نسب بقول: يا بقرة؟> (“lmA*A nsb bqwl: yA bqrp?” – “Why do we insult others by saying: O cow?”); Self offense, ex: تعبت من لساني القذر> (“tEbt mn lsAny Alq*r” – “I am tired of my dirty tongue”); Non-human target, ex: يا بنت المجنونة يا كورة> (“yA bnt Almjnwnp yA kwrp” – “O daughter of the crazy one O football”); and Quotation from a movies or a story, ex: تاني يا زكي! تاني يا فاشل> (“tAny yA zky! tAny yA fA$l” – “again O Zaky! again O loser”). For other ambiguous cases, the annotator searched Twitter to find how actual users used expressions.\nTable TABREF11 shows the distribution of the annotated tweets. There are 1,915 offensive tweets, including 225 vulgar tweet and 506 hate speech tweets, and 8,085 clean tweets. To validate the quality of annotation, a random sample of 100 tweets from the data, containing 50 offensive and 50 clean tweets, was given to additional three annotators. We calculated the Inter-Annotator Agreement between the annotators using Fleiss’s Kappa coefficient BIBREF23. The Kappa score was 0.92 indicating high quality annotation and agreement.\nSince the offensive label covers both vulgar and hate speech and vulgarity and hate speech are not mutually exclusive, a tweet can be just offensive or offensive and vulgar and/or hate speech.",

        "answer": "Tau is defined as the ratio of a circle's circumference to its radius.  Some 21st century mathematicians and physicists believe Tau is a better choice than Pi for use in science and mathematics.\n\nLike Pi, Tau is an irrational and transcendental number.  In decimal form, the value of Tau is 6.283185…\n\nPart of the motivation for Tau is the observation that the number 2*Pi or 2π occurs with surprising frequency throughout science and mathematics.  This raises the question of whether Pi is really an important number or something equal to two times Pi is actually more important.  Perhaps the implication is that Pi is exactly one half of some very important number!\n\nFurther consideration of the question leads to several compelling observations:\n\n\t- Using C/r as the key circle constant is better aligned with the way we define a circle: the set of all points a fixed distance (r) form a give point.\n\t- Radian angle measurements of fraction of a circle make much more sense when Tau is used as the base constant.  Using Pi, on quarter of a circle is Pi is Pi/2, one half is Pi, and the angle of a a full circle is 2*Pi.  With Tau, the angle measures are intuitively aligned to the fraction of a circle: a quarter circle is Tau/4, a half circle is Tau/2 and the angle of a full circle is Tau.  \n\t- Similarly, the radian zeroes, max, and min of the sin and cosine functions align to fractions of Tau in an intuitive fashion that aids, rather than confuses, understanding.\n\t- Key formulas that traditionally use Pi actually show more clear mathematical meaning when expressed using Tau.  For example, the area of a circle itself, when expressed with Tau, shows the same pattern of quadratic forms in distance fallen, spring energy, and kinetic energy.\n\t- Similarly, the tau-based formula for circular area actually confirms to the original proof by Archimedes showing that area of a circle equals the area of a triangle with base C (circumference) and height r (radius):  A = 1/2 b*h = 1/2 C*r = 1/2 (Tau*r)*r = 1/2 Tau*r^2.\n\n\nTau has seen significant adoption since it was originally proposed.  \n\nThe relationship between Tau and Pi is very simple.  Tau = 2*Pi.  Perhaps just as informative is the fact that Tau > Pi.",

        "question": "How does the team fine-tune a sequence of predicted discourse relations?",
        "answer": "By modeling discourse relation continuity and patterns in a paragraph.",
        "evidence": "PDTB-style discourse relations, mostly defined between two adjacent text spans (i.e., discourse units, either clauses or sentences), specify how two discourse units are logically connected (e.g., causal, contrast). Recognizing discourse relations is one crucial step in discourse analysis and can be beneficial for many downstream NLP applications such as information extraction, machine translation and natural language generation.\nCommonly, explicit discourse relations were distinguished from implicit ones, depending on whether a discourse connective (e.g., “because” and “after”) appears between two discourse units BIBREF0 . While explicit discourse relation detection can be framed as a discourse connective disambiguation problem BIBREF1 , BIBREF2 and has achieved reasonable performance (F1 score $>$ 90%), implicit discourse relations have no discourse connective and are especially difficult to identify BIBREF3 , BIBREF2 , BIBREF4 . To fill the gap, implicit discourse relation prediction has drawn significant research interest recently and progress has been made BIBREF5 , BIBREF6 by modeling compositional meanings of two discourse units and exploiting word interactions between discourse units using neural tensor networks or attention mechanisms in neural nets. However, most of existing approaches ignore wider paragraph-level contexts beyond the two discourse units that are examined for predicting a discourse relation in between.\nTo further improve implicit discourse relation prediction, we aim to improve discourse unit representations by positioning a discourse unit (DU) in its wider context of a paragraph. The key observation is that semantic meaning of a DU can not be interpreted independently from the rest of the paragraph that contains it, or independently from the overall paragraph-level discourse structure that involve the DU. Considering the following paragraph with four discourse relations, one relation between each two adjacent DUs:\n(1): [The Butler, Wis., manufacturer went public at $15.75 a share in August 1987,] $_{DU1}$ and (Explicit-Expansion) [Mr. Sim's goal then was a $29 per-share price by 1992.] $_{DU2}$ (Implicit-Expansion) [Strong earnings growth helped achieve that price far ahead of schedule, in August 1988.] $_{DU3}$ (Implicit-Comparison) [The stock has since softened, trading around $25 a share last week and closing yesterday at $23 in national over-the-counter trading.] $_{DU4}$ But (Explicit-Comparison) [Mr. Sim has set a fresh target of $50 a share by the end of reaching that goal.] $_{DU5}$ \nClearly, each DU is an integral part of the paragraph and not independent from other units. First, predicting a discourse relation may require understanding wider paragraph-level contexts beyond two relevant DUs and the overall discourse structure of a paragraph. For example, the implicit “Comparison” discourse relation between DU3 and DU4 is difficult to identify without the background information (the history of per-share price) introduced in DU1 and DU2. Second, a DU may be involved in multiple discourse relations (e.g., DU4 is connected with both DU3 and DU5 with a “Comparison” relation), therefore the pragmatic meaning representation of a DU should reflect all the discourse relations the unit was involved in. Third, implicit discourse relation prediction should benefit from modeling discourse relation continuity and patterns in a paragraph that involve easy-to-identify explicit discourse relations (e.g., “Implicit-Comparison” relation is followed by “Explicit-Comparison” in the above example).\nFollowing these observations, we construct a neural net model to process a paragraph each time and jointly build meaning representations for all DUs in the paragraph. The learned DU representations are used to predict a sequence of discourse relations in the paragraph, including both implicit and explicit relations. Although explicit relations are not our focus, predicting an explicit relation will help to reveal the pragmatic roles of its two DUs and reconstruct their representations, which will facilitate predicting neighboring implicit discourse relations that involve one of the DUs.\nIn addition, we introduce two novel designs to further improve discourse relation classification performance of our paragraph-level neural net model. First, previous work has indicated that recognizing explicit and implicit discourse relations requires different strategies, we therefore untie parameters in the discourse relation prediction layer of the neural networks and train two separate classifiers for predicting explicit and implicit discourse relations respectively. This unique design has improved both implicit and explicit discourse relation identification performance. Second, we add a CRF layer on top of the discourse relation prediction layer to fine-tune a sequence of predicted discourse relations by modeling discourse relation continuity and patterns in a paragraph.\nExperimental results show that the intuitive paragraph-level discourse relation prediction model achieves improved performance on PDTB for both implicit discourse relation classification and explicit discourse relation classification.\nSecond, we add a CRF layer on top of the discourse relation prediction layer to fine-tune a sequence of predicted discourse relations by modeling discourse relation continuity and patterns in a paragraph.",

        "question": "Why is predictability of the future given the past is important for these communicating agents, considering they are memoryless across episodes?",
        "answer": "Predictability of the future given the past is important for these agents, even though they do not store information in an explicit memory module for use across training epochs (i.e. \"memoryless across episodes\"), because: 1) they store knowledge in their gradients and parameters, 2) because the data is sampled without replacement, 3) the data sampling and training dynamics will affect the learned representations.\nWe gave in our common reply how our definition of unpredictability follows Winters et al. (2018), which leads us to a meaningful measure of unpredictability of context in our work in emergent communication.\nWe appreciate that you are aligned with our intuition that “unpredictable environments force the speaker to be maximally informative in its utterances”, and we believe that our proposed metric does provide an informative perspective on this relationship.\nWe agree with your intuition on the effect of predictability, i.e. there’s an implicit effect brought by the data presentation order in the training dynamics. In fact, introducing unpredictability (i.e. variance in the input and input context space) has also been commonly used in the computer vision community. For example, the preprocessing for images used in deep reinforcement learning tasks can include transformations such as random shifts to make the inputs vary across epochs (e.g Kostrikov et al. 2021). The unpredictability/variance of inputs are not explicitly measured by the online learning methods, but the effect of them still can improve the learned representation, which is shown by the improvement of performance (see Figure 1 from Kostrikov et al. 2021).\nTo fully understand the implicit effect caused by the data presentation order covers much wider topics than emergent communication. That said,we look forward to exploring these questions in our future work. In this work, we align with previous related work in cognitive science and proposed our definition of unpredictability in the context of emergent communication, as detailed in Section 3.1.\nRegarding the “online learnability using prequential coding” (Blier and Ollivier 2018), one challenge of this measure in our context is that it would conflate the learnability of emergent languages with the definition of unpredictability. Learnability is a connected research challenge in emergent communication, for example as investigated by Li and Bowling (2019).\nSince we focus on the effect from context on the expressivity of emergent languages, we opted to separate our definition of unpredictability from learnability which is again influenced by both communicating agents and emergent languages. In this work, we focus on the influence of the unpredictability of the contexts from epoch to epoch on expressivity of emergent languages. Similar to learnability, expressivity is also a specific property of emergent languages, which is learned by agents through participation in language games. On the other hand, context is a part of the environment (i.e. part of the definition of the language games), thus its properties and characteristics should be controlled by experimenters as best as possible to understand the influence of agents learning in these environments.\nTherefore, we chose a measure of unpredictability and complexity that can separate the effects from the outputs of the language games including the emergent languages and the trained communicating agents.\nReference: [1] Li, F., & Bowling, M. (2019). Ease-of-teaching and language structure from emergent communication. NeurIPS. [2] Kostrikov, I., Yarats, D., & Fergus, R. (2020).

        "evidence": "Context Communication between humans always takes place w.r.t. some context. For humans, that context includes: 1) features of the environment that can be directly perceived by the dialogue participants and used for interpreting an utterance (e.g. \"cup\" is interpreted as an object in the immediate physical context); and 2) information that cannot be directly perceived but can affect the interpretation of utterances (e.g. using and interpreting \"cup\" assumes some shared knowledge of what counts as a \"cup\"; once a particular cup has been established as salient in particular dialogue, further utterances of \"the cup\" or \"it\" will be interpreted as referring to that specific cup).\nInspired by this conclusion from pragmatics, in the DL-based language games, we define context as the supervision information involved in the calculation of losses, i.e. the context of a specific target x t , denoted as Cpx t q, is the space of samples involved in the calculation of loss. As for in referential games, the cross entropy loss is calculated based on the distance between the message embedding h L pm Bi q and candidate embedding f L cenc px i q where x i P C, thus Cpx t q \" C Ď X in referential games.\nWe assume that the goal of communication is to distinguish a target object from other possibilities in the context (as defined above). It therefore follows that the similarity of distractors in the context to the target influences the communicative precision required, and that greater precision is required to distinguish the target from a more similar distractor. For example, it is relatively easy in natural language to distinguish e.g. a cat from a table (a relatively general label like \"cat\" or \"animal\" would suffice), but harder to make fine-grained distinctions between very similar objects e.g. a Scottish Fold Cat and an American Shorthair Cat (a specialist vocabulary or a lengthy description is necessary). Following the assumption (described verbally above) that a context which contains more similar objects makes the game harder because there are fewer unique features that suffice to distinguish the target from the distractors, we first define a neighbour set in k-th degree of a given target x t as N k px t q \" tx j : dpx t , x j q ď ku where d is a distance function that can properly capture the similarity between inputs, e.g Hamming distance in our setting. The complexity of Cpx t q is then defined as the expectation of the probability that Cpx t q contains an object from N k px t q, i.e. E xt rg pCpx t q, N k px t qqs ,where g pCpx t q, N k px t qq \" \" 1, if Dx i P Cpx t q s.t.\nIn our referential games, since the sampling procedure is independent Bernoulli without replacement, the value of the above expectation is then\n¯|C| which is a monotonically increasing function w.r.t |C| and a fixed k. That said, larger contexts are more complex since they are more likely to include items which are very similar to the target.\nUnpredictability of context Our notion of unpredictability comes from experimental work with human participants, e.g.. Suppose the aim is to distinguish a striped t-shirt from a number of distractors, and there are two sequences of context: 1) three runs of games where distractors are all cups; 2) three runs of games where distractors are a cup, a plain t-shirt, and a pencil. In the first sequence of games, participants would become certain that \"t-shirt\" is enough for distinguishing the target, whereas in the second sequence participants would learn that a more overspecified utterance (e.g. \"striped t-shirt\") is necessary to guarantee comprehension after a failure on the trial involving the plain t-shirt distractor. That is, the context in the first sequence is more predictable than the second. show that human participants are sensitive to this kind of unpredictability, and adapt their communicative strategies accordingly.\nIn DL-based games, we refer to the context at the e-th trial, i.e. the e-th training epoch, of a target x t as C e px t q. Following the above example, the unpredictability of context is then defined as the proportion of C e`1 px t q that are not from C e px t q, i.e.\nIn our referential games, since the sampling procedure is independent Bernoulli without replacement, the proportion of objects not from C e px t q in C e`1 px t q is then simply\n\" 1 ´|C| |X | (i.e. smaller contexts are more unpredictable, since contexts on successive trials are more likely to differ in their composition).\nMore details about the above discussion are provided in Appendix B.\nUnpredictability of context Our notion of unpredictability comes from experimental work with human participants, e.g. Winters et al. (2018). Suppose the aim is to distinguish a striped t-shirt from a number of distractors, and there are two sequences of context: 1) three runs of games where distractors are all cups; 2) three runs of games where distractors are a cup, a plain t-shirt, and a pencil. In the first sequence of games, participants would become certain that “t-shirt” is enough for distinguishing the target, whereas in the second sequence participants would learn that a more overspecified utterance (e.g. \"striped t-shirt\") is necessary to guarantee comprehension after a failure on the trial involving the plain t-shirt distractor. That is, the context in the first sequence is more predictable than the second. Winters et al. (2018) show that human participants are sensitive to this kind of unpredictability, and adapt their communicative strategies accordingly.",

        "answer": "Yes! The original caption stated “Values shown are individual rewards”, but we have rephrased it to emphasize it represents a per agent reward.",
        "evidence": "As we can observe in Table, there is a significant difference in performance between MADDPG-Oracle and MADDPG (MADDPG-Oracle is 123% better on average): this confirms that developing ToM and recurrence is vital to perform successfully in SymmToM. MADDPG-Oracle is often not an upper bound: when c > a, the heuristic performs better (101% on average). This shows that even with perfect information, it can be difficult to learn the optimal policy using MADDPG. Moreover, models with a recurrence mechanism perform significantly better than MADDPG (61% better on average), also showing that remembering past information gives a notable advantage. As expected, having recurrent models tailored to our problem resulted in better performance than a general LSTM recurrence (RMADDPG). The performance of the best of the tailored models (MADDPG-CE, MADDPG-GE, MADDPG-EE) was 42% better on average than plain RMADDPG. LSTM was able to surpass the best of the tailored models only for a = 3, w = 12, c = 3a.\nIncreasing c generally decreases global rewards for learned agents (on average, rewards for c = 2a are 75.54% of those for c = a, and rewards for c = 3a are 75.66% of those for c = a).\nTable: Average rewards per agent in trained models evaluated during 1000 episodes. 7 runs are averaged for each, using the best checkpoint: this compensates for collapses in performance seen in Fig. This suggests that probabilistic decisions are harder to learn, or impossible to successfully navigate when several events are equally likely. MADDPG-EE did not show improvements over the other learned agents, and in some cases decreased its performance more heavily than other learned agents (e.g. w = 6, c = 3a). MADDPG-EE uses an MLP in its definition of S [2] , which gives more flexibility but also implies a more complex function to learn. We leave to future work to explore other probabilistic agents, but the significant difference in performance between all of the learned models and the highest performing ones (MADDPG-Oracle and the heuristic) shows there is ample space for improvement in this task, and hence proves SymmToM to be a simple yet unsolved benchmark.\nIncreasing a results in a 10% reduction of performance on average for learned models. Nonetheless, the heuristic improved its rewards by an average of 46%, given the larger opportunities for rewards when including an additional listener. Overall, this implies that increasing a also makes the setup significantly more difficult. Finally, increasing w did not have a conclusive result: for a = 4 it consistently decreased performance in ∼17%, but for a = 3 we saw an improvement of 16% and 61% for c = a and c = 2a respectively.\nIn sum, modifying c and a provides an easy way of making a setting more difficult without introducing additional rules.\nTable 1: Average rewards per agent in trained models evaluated during 1000 episodes. 7 runs are averaged for each, using the best checkpoint: this compensates for collapses in performance seen in Fig. 5 and Fig. 6.

        "answer": "VP ellipsis.",
        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nAmong the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.",

        "answer": "Bahdanau et al. .",
        "evidence": "Neural Machine Translation (NMT) has shown its effectiveness in translation tasks when NMT systems perform best in recent machine translation campaigns BIBREF0 , BIBREF1 . Compared to phrase-based Statistical Machine Translation (SMT) which is basically an ensemble of different features trained and tuned separately, NMT directly modeling the translation relationship between source and target sentences. Unlike SMT, NMT does not require much linguistic information and large monolingual data to achieve good performances.\nAn NMT consists of an encoder which recursively reads and represents the whole source sentence into a context vector and a recurrent decoder which takes the context vector and its previous state to predict the next target word. It is then trained in an end-to-end fashion to learn parameters which maximizes the likelihood between the outputs and the references. Recently, attention-based NMT has been featured in most state-of-the-art systems. First introduced by BIBREF2 , attention mechanism is integrated in decoder side as feedforward layers. It allows the NMT to decide which source words should take part in the predicting process of the next target words. It helps to improve NMTs significantly. Nevertheless, since the attention mechanism is specific to a particular source sentence and the considering target word, it is also specific to particular language pairs.\nSome recent work has focused on extending the NMT framework to multilingual scenarios. By training such network using parallel corpora in number of different languages, NMT could benefit from additional information embedded in a common semantic space across languages. Basically, the proposed NMT are required to employ multiple encoders or multiple decoders to deal with multilinguality. Furthermore, in order to avoid the tight dependency of the attention mechanism to specific language pairs, they also need to modify their architecture to combine either the encoders or the attention layers. These modifications are specific to the purpose of the tasks as well. Thus, those multilingual NMTs are more complicated, much more free parameters to learn and more difficult to perform standard trainings compared to the original NMT.\nIn this paper, we introduce a unified approach to seamlessly extend the original NMT to multilingual settings. Our approach allows us to integrate any language in any side of the encoder-decoder architecture with only one encoder and one decoder for all the languages involved. Moreover, it is not necessary to do any network modification to enable attention mechanism in our NMT systems. We then apply our proprosed framework in two demanding scenarios: under-resourced translation and zero-resourced translation. The results show that bringing multilinguality to NMT helps to improve individual translations. With some insightful analyses of the results, we set our goal toward a fully multilingual NMT framework.\nThe paper starts with a detailed introduction to attention-based NMT. In Section SECREF3 , related work about multi-task NMT is reviewed. Section SECREF5 describes our proposed approach and thorough comparisons to the related work. It is followed by a section of evaluating our systems in two aforementioned scenarios, in which different strategies have been employed under a unified approach (Section SECREF4 ).

In nineteenth and early twentieth century Europe, artwork was a common form of racialization which targeted countries in the Middle East and Asia. The artwork, predominantly paintings, were portrayed in order to instill prejudice in the Western populations through sexualizing and manipulating images. One of the most prominent examples of Orientalist work in art is a piece by Eugène Delacroix titled Women of Algiers in their Apartment. Dating back to 1834, it portrays three women resting in a harem in exotic clothing while an African woman is dressed in plain clothing, depicting her role as a servant. Fine textiles, hookahs, and other paraphernalia adorn the room, which represents a European fantasy of an exotic scene. Attempts to portray these cultures as strange, foreign and exotic through Orientalism led to intolerance towards the Arab and Asian communities in Europe and the United States. Others argue that Delacroix, who travelled in North Africa sketching extensively, was depicting a realistic scene of the era based on his first-hand knowledge and experience. In such an interpretation the clothing, for example, is consistent with the times, as Arab North Africans dressed differently from Europeans, and kept black slaves who would not have been treated as equals.",

        "evidence": "Hate speech represents written or oral communication that in any way discredits a person or a group based on characteristics such as race, color, ethnicity, gender, sexual orientation, nationality, or religion BIBREF0. Hate speech targets disadvantaged social groups and harms them both directly and indirectly BIBREF1. Social networks like Twitter and Facebook, where hate speech frequently occurs, receive many critics for not doing enough to deal with it. As the connection between hate speech and the actual hate crimes is high BIBREF2, the importance of detecting and managing hate speech is not questionable. Early identification of users who promote such kind of communication can prevent an escalation from speech to action. However, automatic hate speech detection is difficult, especially when the text does not contain explicit hate speech keywords. Lexical detection methods tend to have low precision because, during classification, they do not take into account the contextual information those messages carry BIBREF3. Recently, contextual word and sentence embedding methods capture semantic and syntactic relation among the words and improve prediction accuracy.\nRecent works on combining probabilistic Bayesian inference and neural network methodology attracted much attention in the scientific community BIBREF4. The main reason is the ability of probabilistic neural networks to quantify trustworthiness of predicted results. This information can be important, especially in tasks were decision making plays an important role BIBREF5. The areas which can significantly benefit from prediction uncertainty estimation are text classification tasks which trigger specific actions. Hate speech detection is an example of a task where reliable results are needed to remove harmful contents and possibly ban malicious users without preventing the freedom of speech. In order to assess the uncertainty of the predicted values, the neural networks require a Bayesian framework. On the other hand, Srivastava et al. BIBREF6 proposed a regularization approach, called dropout, which has a considerable impact on the generalization ability of neural networks. The approach drops some randomly selected nodes from the neural network during the training process. Dropout increases the robustness of networks and prevents overfitting. Different variants of dropout improved classification results in various areas BIBREF7. Gal and Ghahramani BIBREF8 exploited the interpretation of dropout as a Bayesian approximation and proposed a Monte Carlo dropout (MCD) approach to estimate the prediction uncertainty. In this paper, we analyze the applicability of Monte Carlo dropout in assessing the predictive uncertainty.\nOur main goal is to accurately and reliably classify different forms of text as hate or non-hate speech, giving a probabilistic assessment of the prediction uncertainty in a comprehensible visual form. We also investigate the ability of deep neural network methods to provide good prediction accuracy on small textual data sets. The outline of the proposed methodology is presented in Figure FIGREF2.\nOur main contributions are:\ninvestigation of prediction uncertainty assessment to the area of text classification,\nimplementation of hate speech detection with reliability output,\nevaluation of different contextual embedding approaches in the area of hate speech,\na novel visualization of prediction uncertainty and errors of classification models.\nThe paper consists of six sections. In Section 2, we present related works on hate speech detection, prediction uncertainty assessment in text classification context, and visualization of uncertainty. In Section 3, we propose the methodology for uncertainty assessment using dropout within neural network models, as well as our novel visualization of prediction uncertainty. Section 4 presents the data sets and the experimental scenario. We discuss the obtained results in Section 5 and present conclusions and ideas for further work in Section 6.\nIn this paper, we analyze the applicability of Monte Carlo dropout in assessing the predictive uncertainty.",

        "evidence": "Natural text generation, as a key task in NLP, has been advanced substantially thanks to the flourish of neural models BIBREF0 , BIBREF1 . Typical frameworks such as sequence-to-sequence (seq2seq) have been applied to various generation tasks, including machine translation BIBREF2 and dialogue generation BIBREF3 . The standard paradigm to train such neural models is maximum likelihood estimation (MLE), which maximizes the log-likelihood of observing each word in the text given the ground-truth proceeding context BIBREF4 .\nAlthough widely used, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 : during test, the model sequentially predicts the next word conditioned on its previous generated words while during training conditioned on ground-truth words. To tackle this problem, generative adversarial networks (GAN) with reinforcement learning (RL) training approaches have been introduced to text generation tasks BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , where the discriminator is trained to distinguish real and generated text samples to provide reward signals for the generator, and the generator is optimized via policy gradient BIBREF7 .\nHowever, recent studies have shown that potential issues of training GANs on discrete data are more severe than exposure bias BIBREF14 , BIBREF15 . One of the fundamental issues when generating discrete text samples with GANs is training instability. Updating the generator with policy gradient always leads to an unstable training process because it's difficult for the generator to derive positive and stable reward signals from the discriminator even with careful pre-training BIBREF8 . As a result, the generator gets lost due to the high variance of reward signals and the training process may finally collapse BIBREF16 .\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation. At each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples. Then, inspired by reward augmented maximum likelihood (RAML) BIBREF17 , the generator is updated on the samples acquired from a stationary distribution with maximum likelihood estimation (MLE), weighted by the discriminator's rewards. This stationary distribution is designed to guarantee that training samples are surrounding the real data, thus the exploration space of our generator is indeed restricted by the MLE training objective, resulting in more stable training. Compared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient. Our contributions are mainly as follows:\nOur contributions are mainly as follows: • We analyze the fundamental issue of current GANs for text generation from the perspectives of training instability. • We propose a novel framework called Adversarial Reward Augmented Maximum Likelihood (ARAML), which incorporates stable RAML training into adversarial training paradigm.

        "question": "Given these paragraphs about Large language models, what is Instruction tuning?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

        "question": "Give me a one line summary of the story below: \n\nA long long time ago the Queen of Odisha heard that there was a master stone sculptor who made such stunning statues of the gods that people would weep from happiness at the beauty of the statues if they saw them. One summer day, while resting indolently with the King in the main hall of the royal palace, the Queen suddenly had a thought. \"How nice it would be, King, if we could build some beautiful statutes of Lord Jagannath so that the people can come worship Jagannath, Balabhadra, and Subadhra. What do you think?\" \n\nThe King thought for a few minutes, and then nodded in agreement. \"What do you have in mind, my Queen?\" And so, soon the stone sculptor was summoned to appear before the Court for an appointment to build in his way the statutes of the gods. Soon the monsoon season started and the sculptor appeared in front of the court, awaiting his appointment. He was a humble man from the mountainous regions of Odisha. Even at his best-dressed, one couldn't help but notice his rough hands, and the small sprinkling of dust that seemed ever present in his hair. \n\nThe King and Queen graciously waited as the sculptor bowed and then asked \"Your majesties, what can I do for you?\" The Queen leaned forward in her throne and her voice rang out in the court \"We have heard, o Master Sculptor, of your skills from people far and wide across the Kingdom. We dream of having you put your skills to use to build beautiful statues that will represent Lord Jagannath, Subhadra, and Balabhadra for our people to worship.\"\n\nThe sculptor was silent. As his silence extended, ministers of the court began to feel restless. \"Speak up! How can you be silent when the Queen graces you so!\" But still, the sculptor was silent. \n\nThe King and Queen sat patiently in their thrones as they waited for the sculptor to respond. Perhaps the enormity of the task was too much. Perhaps, the sculptor was thinking of what he should ask for in return. Or even more, perhaps, the sculptor was awed and honored by the request. \n\nAt last, as the shadows from the late afternoon sun began to stretch across the floors of the hall, the sculptor shifted his weight, and opened his mouth to speak. \"Your majesties, you grace me with such a request, I cannot help but oblige. It is an honor.\" At this, the Queen sat as straight as a rod, listening for the words that would come next. \"But, I can do this on one condition only. I will work in a closed hall, where none may enter - regardless of whether they can hear me working or otherwise. None may enter until I open the doors from within and proclaim to all that the statues are completed.\"\n\nThe ministers gasped - what a strange request from this man. Was he a fool? What if he just slept and ate and didn't do any work? How could the King and Queen trust that he would do the work he was promising to do? The Queen looked on thoughtfully. She glanced at the King, and it seemed to her that he agreed on this condition without reservation. She looked at the sculptor and then nodded her assent. \"We decree that you shall build these statues in a hall set aside, into which no one shall enter until your work is complete and you proclaim that to us after opening the doors of the hall from within.\"",

Perhaps they want your attention, or they might be fearful or anxious and are barking to alert you. Also, barking habits can also be very breed specific. Some breeds are known to be more vocal than other breeds. It's important to try and understand why they are barking to then initiate the proper course of action to address their barking habits. If you believe they are barking for attention, one idea is to make sure you are not rewarding their barking by distracting them with a treat or playtime. By doing this, you are teaching them that if they bark, the dog will get what they want. Instead, you might want to consider a couple items. First, is the dog getting enough exercise or releasing their energy. Increase their stimulation by walking them more, playing with them, or socializing them with other dogs or humans. This added stimulation may reduce their need for attention. If they are barking because they are fearful or anxious, think about what is happening or what the environment is that may be cause their fear or anxiety. Then, try and change the environment or situation so the dog feels safe. One action that may help is providing a safe place for your dog, such as a dog crate or dog bed, so they know exactly what to do when they are afraid or anxious. Training them to go to their safe place may provide the comfort they need to reduce their barking habits.",

Chromosomal deletion syndromes typically involve larger deletions that are visible using karyotyping techniques. Smaller deletions result in Microdeletion syndrome, which are detected using fluorescence in situ hybridization (FISH)\n\nExamples of chromosomal deletion syndromes include 5p-Deletion (cri du chat syndrome), 4p-Deletion (Wolf–Hirschhorn syndrome), Prader–Willi syndrome, and Angelman syndrome.\n\nThe chromosomal basis of Cri du chat syndrome consists of a deletion of the most terminal portion of the short arm of chromosome 5. 5p deletions, whether terminal or interstitial, occur at different breakpoints; the chromosomal basis generally consists of a deletion on the short arm of chromosome 5. The variability seen among individuals may be attributed to the differences in their genotypes. With an incidence of 1 in 15,000 to 1 in 50,000 live births, it is suggested to be one of the most common contiguous gene deletion disorders. 5p deletions are most common de novo occurrences, which are paternal in origin in 80–90% of cases, possibly arising from chromosome breakage during gamete formation in males.\n\nSome examples of the possible dysmorphic features include: downslanting palpebral fissures, broad nasal bridge, microcephaly, low-set ears, preauricular tags, round faces, short neck, micrognathia, and dental malocclusionhypertelorism, epicanthal folds, downturned corners of the mouth. There is no specific correlation found between size of deletion and severity of clinical features because the results vary so widely.\n\nThe chromosomal basis of Wolf-Hirschhorn syndrome (WHS) consists of a deletion of the most terminal portion of the short arm of chromosome 4. The deleted segment of reported individuals represent about one half of the p arm, occurring distal to the bands 4p15.1-p15.2. The proximal boundary of the WHSCR was defined by a 1.9 megabase terminal deletion of 4p16.3. This allele includes the proposed candidate genes LEMT1 and WHSC1. This was identified by two individuals that exhibited all 4 components of the core WHS phenotype, which allowed scientists to trace the loci of the deleted genes. Many reports are particularly striking in the appearance of the craniofacial structure (prominent forehead, hypertelorism, the wide bridge of the nose continuing to the forehead) which has led to the descriptive term “Greek warrior helmet appearance\".\n\nThere is wide evidence that the WHS core phenotype (growth delay, intellectual disability, seizures, and distinctive craniofacial features) is due to haploinsufficiency of several closely linked genes as opposed to a single gene. Related genes that impact variation include:\n\nWHSC1 spans a 90-kb genomic region, two-thirds of which maps in the telomeric end of the WHCR; WHSC1 may play a significant role in normal development. Its deletion likely contributes to the WHS phenotype. However, variation in severity and phenotype of WHS suggests possible roles for genes that lie proximally and distally to the WHSCR.\nWHSC2 (also known as NELF-A) is involved in multiple aspects of mRNA processing and the cell cycle\nSLBP, a gene encoding Stem Loop Binding Protein, resides telomeric to WHSC2, and plays a crucial role in regulating histone synthesis and availability during S phase.\nLETM1 has initially been proposed as a candidate gene for seizures; it functions in ion exchange with potential roles in cell signaling and energy production.\nFGFRL1, encoding a putative fibroblast growth factor decoy receptor, has been implicated in the craniofacial phenotype and potentially other skeletal features, and short stature of WHS.\nCPLX1 has lately been suggested as a potential candidate gene for epilepsy in WHS.\n\nPrader–Willi (PWS) and Angelman syndrome (AS) are distinct neurogenetic disorders caused by chromosomal deletions, uniparental disomy or loss of the imprinted gene expression in the 15q11-q13 region. Whether an individual exhibits PWS or AS depends on if there is a lack of the paternally expressed gene to contribute to the region.[citation needed]\n\nPWS is frequently found to be the reason for secondary obesity due to early onset hyperphagia - the abnormal increase in appetite for consumption of food. There are known three molecular causes of Prader–Willi syndrome development. One of them consists in micro-deletions of the chromosome region 15q11–q13. 70% of patients present a 5–7-Mb de novo deletion in the proximal region of the paternal chromosome 15. The second frequent genetic abnormality (~ 25–30% of cases) is maternal uniparental disomy of chromosome 15. The mechanism is due to maternal meiotic non-disjunction followed by mitotic loss of the paternal chromosome 15 after fertilization. The third cause for PWS is the disruption of the imprinting process on the paternally inherited chromosome 15 (epigenetic phenomena). This disruption is present in approximately 2–5% of affected individuals. Less than 20% of individuals with an imprinting defect are found to have a very small deletion in the PWS imprinting centre region, located at the 5′ end of the SNRPN gene.\n\nAS is a severe debilitating neurodevelopmental disorder characterized by mental retardation, speech impairment, seizures, motor dysfunction, and a high prevalence of autism. The paternal origin of the genetic material that is affected in the syndrome is important because the particular region of chromosome 15 involved is subject to parent-of-origin imprinting, meaning that for a number of genes in this region, only one copy of the gene is expressed while the other is silenced through imprinting. For the genes affected in PWS, it is the maternal copy that is usually imprinted (and thus is silenced), while the mutated paternal copy is not functional.",

Suddenly, I saw a shadow pass behind me and someone grabbed me from behind and tried to wrestle my keys away from me.\nToo bad for him, he didn't realize that I'm a UFC champion. Lucky for him,  he only ended up with a missing tooth. It took a while for the police to show up so that's why I was late.",

        "question": "Give me the main facts about the book series about Harry Potter.",
        "evidence": "Harry Potter is a series of seven fantasy novels written by British author J. K. Rowling. The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's conflict with Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic and subjugate all wizards and Muggles (non-magical people).\n\nThe series was originally published in English by Bloomsbury in the United Kingdom and Scholastic Press in the United States. All versions around the world are printed by Grafica Veneta in Italy. A series of many genres, including fantasy, drama, coming-of-age fiction, and the British school story (which includes elements of mystery, thriller, adventure, horror, and romance), the world of Harry Potter explores numerous themes and includes many cultural meanings and references. According to Rowling, the main theme is death. Other major themes in the series include prejudice, corruption, and madness.\n\nSince the release of the first novel, Harry Potter and the Philosopher's Stone, on 26 June 1997, the books have found immense popularity, positive reviews, and commercial success worldwide. They have attracted a wide adult audience as well as younger readers and are widely considered cornerstones of modern literature. As of February 2023, the books have sold more than 600 million copies worldwide, making them the best-selling book series in history, and have been available in 85 languages. The last four books consecutively set records as the fastest-selling books in history, with the final instalment selling roughly 2.7 million copies in the United Kingdom and 8.3 million copies in the United States within twenty-four hours of its release.\n\nThe original seven books were adapted into an eight-part namesake film series by Warner Bros. Pictures. In 2016, the total value of the Harry Potter franchise was estimated at $25 billion, making Harry Potter one of the highest-grossing media franchises of all time. Harry Potter and the Cursed Child is a play based on a story co-written by Rowling.\n\nThe success of the books and films has allowed the Harry Potter franchise to expand with numerous derivative works, a travelling exhibition that premiered in Chicago in 2009, a studio tour in London that opened in 2012, a digital platform on which J. K. Rowling updates the series with new information and insight, and a pentalogy of spin-off films premiering in November 2016 with Fantastic Beasts and Where to Find Them, among many other developments. Themed attractions, collectively known as The Wizarding World of Harry Potter, have been built at several Universal Destinations & Experiences amusement parks around the world.",

        "question": "What is reserve requirement?",
        "evidence": "",
        "answer": "Reserve requirements are central bank regulations that set the minimum amount that a commercial bank must hold in liquid assets. This minimum amount, commonly referred to as the commercial bank's reserve, is generally determined by the central bank on the basis of a specified proportion of deposit liabilities of the bank. This rate is commonly referred to as the reserve ratio. Though the definitions vary, the commercial bank's reserves normally consist of cash held by the bank and stored physically in the bank vault (vault cash), plus the amount of the bank's balance in that bank's account with the central bank. A bank is at liberty to hold in reserve sums above this minimum requirement, commonly referred to as excess reserves.\n\nThe reserve ratio is sometimes used by a country’s monetary authority as a tool in monetary policy, to influence the country's money supply by limiting or expanding the amount of lending by the banks. Monetary authorities increase the reserve requirement only after careful consideration because an abrupt change may cause liquidity problems for banks with low excess reserves; they generally prefer to use open market operations (buying and selling government-issued bonds) to implement their monetary policy. In the United States and many other countries (except Brazil, China, India, Russia), reserve requirements are generally not altered frequently in implementing a country's monetary policy because of the short-term disruptive effect on financial markets.",

        "evidence": "We have shown that ERP components can be predicted from neural networks pretrained as language models and fine-tuned to directly predict those components. To the best of our knowledge, prior work has not successfully used statistical models to predict all of these components. Furthermore, we have shown that multitask learning benefits the prediction of ERP components and can suggest how components relate to each other. At present, these joint-training benefit relationships are only suggestive, but if these relationships ultimately lead to insights about what drives each ERP component, then the components become more useful tools for studying human language comprehension. By using multitask learning as a method of characterization, we have found some expected relationships (LAN+P600 and ELAN+P600) and several more surprising relationships. We believe that this is exactly the kind of finding that makes multitask learning an interesting exploratory technique in this area. Additionally, we have shown that information can be shared between heterogeneous types of data (eye-tracking, self-paced reading, and ERP components) in the domain of human language processing prediction, and in particular between behavioral and neural data. Given the small datasets associated with human language processing, using heterogeneous data is a potentially major advantage of a multitask approach. In future work, we will further explore what information is encoded into the model representations when neural and behavioral data are used to train neural networks, and how these representations differ from the representations in a model trained on language alone.\nIn future work, we will further explore what information is encoded into the model representations when neural and behavioral data are used to train neural networks, and how these representations differ from the representations in a model trained on language alone.",

We ran UTD over all 104 telephone calls, which pair 11 hours of audio with Spanish transcripts and their crowdsourced English translations. The transcripts contain 168,195 Spanish word tokens (10,674 types), and the translations contain 159,777 English word tokens (6,723 types). Though our system does not require Spanish transcripts, we use them to evaluate UTD and to simulate a perfect UTD system, called the oracle.\nFor MT training, we use the pseudotext and translations of 50 calls, and we filter out stopwords in the translations with NLTK BIBREF15 . Since UTD is better at matching patterns from the same speaker (§ SECREF8 ), we created two types of 90/10% train/test split: at the call level and at the utterance level. For the latter, 90% of the utterances are randomly chosen for the training set (independent of which call they occur in), and the rest go in the test set. Hence at the utterance level, but not the call level, some speakers are included in both training and test data. Although the utterance-level split is optimistic, it allows us to investigate how multiple speakers affect system performance. In either case, the oracle has about 38k Spanish tokens to train on.\nAlthough we did not have access to a low-resource dataset, there is a corpus of noisy multi-speaker speech that simulates many of the conditions we expect to find in our motivating applications: the CALLHOME Spanish–English speech translation dataset (LDC2014T23; Post el al., 2013).",

For instance, the 1948 ABL finalist Baltimore Bullets moved to the BAA and won that league's 1948 title, and the 1948 NBL champion Minneapolis Lakers won the 1949 BAA title. Prior to the 1948–49 season, however, NBL teams from Fort Wayne, Indianapolis, Minneapolis, and Rochester jumped to the BAA, which established the BAA as the league of choice for collegians looking to turn professional.\n\nOn August 3, 1949, the remaining NBL teams–Syracuse, Anderson, Tri-Cities, Sheboygan, Denver, and Waterloo–merged into the BAA. In deference to the merger and to avoid possible legal complications, the league name was changed to the present National Basketball Association, even though the merged league retained the BAA's governing body, including Maurice Podoloff as president. To this day, the NBA claims the BAA's history as its own. It now reckons the arrival of the NBL teams as an expansion, not a merger, and does not recognize NBL records and statistics.",

Originating from the NLP domain, where the transformer architectures has been a key ingredient and subject to optimization in a multitude of ways, it has recently found applications in the vision-language domain. For example, recent works have leveraged transformers to learn generalizeable image or multi-modal image-text and video-multilingual text representations. A few works combine visual and text modalities as inputs to a BERT model to simultaneously learn semantic video and text representations. For representation learning, the availability of large-scale datasets such as HowTo100M has enabled more effective pretraining of video-text representations for multiple downstream tasks. More recently, show that adding a generative objective to contrastive pretraining can yield gains in video-text downstream tasks. Based on the CLIP model, which works well even without finetuning for some retrieval tasks, train video-text CLIP-initialized models by gradually scaling up video training from image training and a custom dataset. While we also start with a CLIP initialization as in, the focus of our paper lies in developing a novel method for leveraging user comments, a modality that has previously been overlooked in the text-video retrieval literature, as a valuable source of information. As is standard, the pretrained representations are subsequently evaluated on smaller datasets such as MSVD and MSR-VTT.\nMulti-modal domain adaptation. While residual adapters for domain adaptation have been explored for uni-modal models such as CNNs, e.g. in, there are no works that translate this concept to the multi-modal domain, where cross-modal learning dominates.\nThere is little prior work using user comments as additional context in multimodal settings. The use of user comments and reactions to refine predictions has been discussed by for minimising harms on facebook.com.

As training samples, individual scenes of plays written by Shakespeare, Fletcher, and Massinger are used that come roughly from the period when H8 was supposedly written, namely:\nShakespeare: The Tragedy of Coriolanus (5 scenes), The Tragedy of Cymbeline (27 scenes), The Winter’s Tale (12 scenes), The Tempest (9 scenes)\nFletcher: Valentinian (21 scenes), Monsieur Thomas (28 scenes), The Woman’s Prize (23 scenes), Bonduca (18 scenes)\nMassinger: The Duke of Milan (10 scenes), The Unnatural Combat (11 scenes), The Renegado (25 scenes)\nAltogether there are thus 53 training samples for Shakespeare, 90 training samples for Fletcher and 46 training samples for Massinger. In order to estimate the accuracy of the model, cross-validation is performed in the following way:\nTo avoid the risk of overfitting which may be caused by testing the model on the scenes from the same play as it was trained on, we do not perform a standard k-fold cross validation. Instead, we classify scenes of each play by a model trained on the rest, i.e. 5 scenes of Shakespeare’s Coriolanus are classified by a model trained on the scenes from the remaining 3 plays by Shakespeare, 4 plays by Fletcher and 5 plays by Massinger, 27 scenes of Cymbeline are classified in the same way and so on.\nSince the training data are imbalanced (which may bias the results), we level the number of training samples per author by random selection.\nTo obtain more representative results, the entire process is repeated 30 times (with a new random selection in each iteration) thus resulting in 30 classifications of each scene.\nFor the sake of comparison of the attribution power of both feature subsets, cross-validations are performed not only of the combined models (500 words $\\cup $ 500 rhythmic types), but also of the words-based models (500 words) and versification-based models (500 rhythmic types) alone.\nAs shown in Table TABREF14, the versification-based models yield a very high accuracy with the recognition of Shakespeare and Fletcher (0.97 to 1 with the exception of Valentinian), yet slightly lower accuracy with the recognition of Massinger (0.81 to 0.88). The accuracy of words-based models remains very high across all three authors (0.95 to 1); in three cases it is nevertheless outperformed by the combined model. We thus may conclude that combined models provide a reliable discriminator between Shakespeare’s, Fletcher’s and Massinger’s styles.\nTable TABREF19 gives the results of the classifiers when applied to the individual scenes of H8 on the basis of which we may conclude:\nIt is very unlikely that Massinger took part in the text of H8. Out of 17 scenes only 2 are attributed to Massinger by any of the models (2.1, 4.2), and in both cases by a mere minority of votes.\nThe probability that the text of H8 is a result of collaboration between Shakespeare and Fletcher is very high: with 7 scenes all the 30 models agree upon Shakespeare’s authorship, with 5 scenes all the 30 models agree upon Fletcher’s authorship.\nOur results correspond to the Spedding’s attribution to a high extent. With the exception of two scenes, the majority of models always predict the same author to which it is attributed by Spedding. The two exceptions are the second scene of act 3, where Spedding supposed mixed authorship, and the first scene of act 4, which was originally attributed to Fletcher.\nIn the first experiment we perform an attribution of individual scenes of H8 using the Support Vector Machine as a classifier and the frequencies of 500 most frequent rhythmic types and the frequencies of 500 most frequent words as a feature set.",

Reducing the word order divergence can improve translation in extremely low-resource scenarios.\nAn analysis of the outputs revealed that pre-ordering significantly reducing the number of UNK tokens (placeholder for unknown words) in the test output (Table TABREF14 ). We hypothesize that due to word order divergence between English and Indian languages, the encoder representation generated is not consistent leading to decoder generating unknown words. However, the pre-ordered models generate better contextual representations leading to less number of unknown tokens and better translation which is also reflected in the BLEU scores.\nWe experiment with two scenarios: (a) an extremely resource scarce scenario with no parallel corpus for child tasks, (b) varying amounts of parallel corpora available for child task.",

        "question": "Does using a context recurrent neural network (RNN) to read representations at the utterance-level allow for a more top-down perspective on the dialogue history?",
        "answer": "Yes, it does.",
        "evidence": "Recently, chit-chat dialogue models have achieved improved performance in modelling a variety of conversational domains, including movie subtitles, Twitter chats and help forums BIBREF0, BIBREF1, BIBREF2, BIBREF3. These neural systems were used to model conversational dialogue via training on large chit-chat datasets such as the OpenSubtitles corpus, which contains generic dialogue conversations from movies BIBREF4. The datasets used do not have an explicit dialogue state to be modelled BIBREF5, but rather require the agent to learn the nuances of natural language in the context of casual peer-to-peer interaction.\nMany recent chit-chat systems BIBREF2, BIBREF3 attempt to introduce increased diversity into model responses. However, dialogue systems have also been known to suffer from a lack of coherence BIBREF0. Given an input message history, systems often have difficulty tracking important information such as professions and names BIBREF0. It would be of benefit to create a system which extracts relevant features from the input that indicate which responses would be most appropriate, and conditions on this stored information to select the appropriate response.\nA major problem with existing recurrent neural network (RNN) architectures is that these systems aggregate all input tokens into a state vector, which is passed to a decoder for generation of the final response, or in the case of a neural probabilistic language model BIBREF6, the state at each time step is used to predict the next token in the sequence. Ideally the size of the state should expand with the number of input tokens and should not lose important information about the input. However, RNN states are typically fixed sized, and for any chosen state size, there exists an input sequence length for which the RNN would not be able to store all relevant details for a final response. In addition, the RNN state undergoes constant transformation at each computational step. This makes it difficult to maintain a persistent storage of information that remains constant over many time steps.\nThe introduction of attention mechanisms BIBREF7 has sparked a change in the current design of RNN architectures. Instead of relying fully on a fixed-sized state vector, an attention mechanism allows each decoder word prediction step to extract relevant information from past states through a key-value query mechanism. However, this mechanism connects every input token with all preceeding ones via a computational step, increasing the complexity of the calculation to $O(N^2)$ for an input sequence size N. In the ideal case, the mapping of input conversation history to output response would have a computational complexity of $O(N)$. For this reason, it is desirable to have an information retrieval system that is both scale-able, but not proportional to input length.\nWe study the impact of accessible memory on response coherence by constructing a memory-augmented dialogue system. The motivation is that it would be beneficial to store details of the conversational history in a more permanent memory structure, instead of being captured inside a fixed-sized RNN hidden state. Our proposed system is able to both read and write to a persistent memory module after reading each input utterance. As such, it has access to a stable representation of the input message history when formulating a final response. We explore two distinct memory architectures with different properties, and compare their differences and benefits. We evaluate our proposed memory systems using perplexity evaluation, and compare them to competitive baselines.\nThey show that using a context recurrent neural network (RNN) to read representations at the utterance-level allows for a more top-down perspective on the dialogue history.",

        "evidence": "Text summarization is a task to generate a shorter and concise version of a text while preserving the meaning of the original text. The task can be divided into two subtask based on the approach: extractive and abstractive summarization. Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T).",

        "evidence": "Sealing the food in sturdy plastic bags retains juices and aroma that otherwise would be lost in the process. Placing the packaged food in a water bath, with the temperature set at the desired final cooking temperature of the food, prevents overcooking, because the food cannot get hotter than the bath it is in, as in bain-marie.\n\nAs a result of precise temperature control of the bath and the fact that the bath temperature is the same as the target cooking temperature, very precise control of cooking can be achieved. Additionally, temperature, and thus cooking, can be very even throughout the food in sous vide cooking, even with irregularly shaped and very thick items, given enough time.",
        "answer": "By contrast, in conventional high-heat cooking, such as oven roasting or grilling, the food is exposed to heat levels that are much higher than the desired internal cooking temperature, and it must be removed from the high heat prior to reaching the desired cooking temperature. If the food is removed from the heat too late, it becomes overcooked, and if it is removed too early, it is undercooked.\n\nThe use of temperatures much lower than those used for conventional cooking is an essential feature of sous vide. When cooking meat, tough collagen in connective tissue can be denatured into gelatin, without heating the meat's proteins high enough that they denature to a degree that the texture toughens and moisture is exuded from the meat.\n\nIn contrast, soft vegetables are often considered overcooked. Low-temperature cooking allows plant matter to remain more succulent, as the cell walls do not burst. Cooking vegetables at temperatures below the boiling point of water allows them to be thoroughly cooked (and pasteurized, if necessary) while maintaining a firm or somewhat crisp texture. While the cell walls will generally not burst, the depolymerization of the pectic polysaccharides that connect the vegetable cells together and the gelatinisation of starch in the vegetable can be achieved without overcooking.\n\nFrom a culinary viewpoint, the exclusion of air is secondary, but this has practical importance. It allows cooked food to be stored, still sealed and refrigerated, for considerable times, which is especially useful for the catering industry, and it excludes oxygen from food that requires long cooking and is susceptible to oxidation, e.g., fat on meat, which may become rancid with prolonged exposure to air. It also improves the transfer of heat between the water bath and food, without the thermal insulating properties of any trapped air in the bag.\n\nApart from ensuring uniform cooking, sous vide cooking facilitates development of desired organoleptic flavors and limits off flavors due to oxidation",

        "evidence": "Writing errors can occur in many different forms – from relatively simple punctuation and determiner errors, to mistakes including word tense and form, incorrect collocations and erroneous idioms. Automatically identifying all of these errors is a challenging task, especially as the amount of available annotated data is very limited. Rei2016 showed that while some error detection algorithms perform better than others, it is additional training data that has the biggest impact on improving performance.\nBeing able to generate realistic artificial data would allow for any grammatically correct text to be transformed into annotated examples containing writing errors, producing large amounts of additional training examples. Supervised error generation systems would also provide an efficient method for anonymising the source corpus – error statistics from a private corpus can be aggregated and applied to a different target text, obscuring sensitive information in the original examination scripts. However, the task of creating incorrect data is somewhat more difficult than might initially appear – naive methods for error generation can create data that does not resemble natural errors, thereby making downstream systems learn misleading or uninformative patterns.\nPrevious work on artificial error generation (AEG) has focused on specific error types, such as prepositions and determiners BIBREF0 , BIBREF1 , or noun number errors BIBREF2 . Felice2014a investigated the use of linguistic information when generating artificial data for error correction, but also restricting the approach to only five error types. There has been very limited research on generating artificial data for all types, which is important for general-purpose error detection systems. For example, the error types investigated by Felice2014a cover only 35.74% of all errors present in the CoNLL 2014 training dataset, providing no additional information for the majority of errors.\nIn this paper, we investigate two supervised approaches for generating all types of artificial errors. We propose a framework for generating errors based on statistical machine translation (SMT), training a model to translate from correct into incorrect sentences. In addition, we describe a method for learning error patterns from an annotated corpus and transplanting them into error-free text. We evaluate the effect of introducing artificial data on two error detection benchmarks. Our results show that each method provides significant improvements over using only the available training set, and a combination of both gives an absolute improvement of 4.3% in INLINEFORM0 , without requiring any additional annotated data.\n \nOur results show that each method provides significant improvements over using only the available training set, and a combination of both gives an absolute improvement of 4.3% in F0.5, without requiring any additional annotated data.",

        "question": "What is the diversity metric set for?",
        "answer": "For observation of how the Part-of-Speech tags are distributed in the question texts,",
        "evidence": "In this section, we identify various linguistic activities on Quora and propose quantifications of the language usage patterns in this Q&A site. In particular, we show that there exists significant differences in the linguistic structure of the open and the answered questions. Note that most of the measures that we define are simple, intuitive and can be easily obtained automatically from the data (without manual intervention). Therefore the framework is practical, inexpensive and highly scalable.\nContent of a question text is important to attract people and make them engage more toward it. The linguistic structure (i.e., the usage of POS tags, the use of Out-of-Vocabulary words, character usage etc.) one adopts are key factors for answerability of questions. We shall discuss the linguistic structure that often represents the writing style of a question asker.\nIn fig 1 (a), we observe that askers of open questions generally use more no. of words compared to answered questions. To understand the nature of words (standard English words or chat-like words frequently used in social media) used in the text, we compare the words with GNU Aspell dictionary to see whether they are present in the dictionary or not. We observe that both open questions and answered questions follow similar distribution (see fig 1 (b)). Part-of-Speech (POS) tags are indicators of grammatical aspects of texts. To observe how the Part-of-Speech tags are distributed in the question texts, we define a diversity metric. We use the standard CMU POS tagger BIBREF8 for identifying the POS tags of the constituent words in the question. We define the POS tag diversity (POSDiv) of a question $q_i$ as follows: $POSDiv(q_i) = -\\sum _{j \\in pos_{set}}p_j\\times \\log (p_j)$ where $p_j$ is the probability of the $j^{th}$ POS in the set of POS tags. Fig 1 (c) shows that the answered questions have lower POS tag diversity compared to open questions. Question texts undergo several edits so that their readability and the engagement toward them are enhanced. It is interesting to identify how far such edits can make the question different from the original version of it. To capture this phenomena, we have adopted ROUGE-LCS recall BIBREF9 from the domain of text summarization. Higher the recall value, lesser are the changes in the question text. From fig 1 (d), we observe that open questions tend to have higher recall compared to the answered ones which suggests that they have not gone through much of text editing thus allowing for almost no scope of readability enhancement.\nPsycholinguistic analysis: \nThe way an individual talks or writes, give us clue to his/her linguistic, emotional, and cognitive states. A question asker's linguistic, emotional, cognitive states are also revealed through the language he/she uses in the question text. In order to capture such psycholinguistic aspects of the asker, we use Linguistic Inquiry and Word Count (LIWC) BIBREF10 that analyzes various emotional, cognitive, and structural components present in individuals' written texts. LIWC takes a text document as input and outputs a score for the input for each of the LIWC categories such as linguistic (part-of-speech of the words, function words etc.) and psychological categories (social, anger, positive emotion, negative emotion, sadness etc.) based on the writing style and psychometric properties of the document. In table 1 , we perform a comparative analysis of the asker's psycholinguistic state while asking an open question and an answered question.\nAskers of open questions use more function words, impersonal pronouns, articles on an average whereas asker of answered questions use more personal pronouns, conjunctions and adverbs to describe their questions. Essentially, open questions lack content words compared to answered questions which, in turn, affects the readability of the question. As far as the psychological aspects are concerned, answered question askers tend to use more social, family, human related words on average compared to an open question asker. The open question askers express more positive emotions whereas the answered question asker tend to express more negative emotions in their texts. Also, answered question askers are more emotionally involved and their questions reveal higher usage of anger, sadness, anxiety related words compared to that of open questions. Open questions, on the other hand, contains more sexual, body, health related words which might be reasons why they do not attract answers.\nIn table 2 , we show a collection of examples of open questions to illustrate that many of the above quantities based on the linguistic activities described in this section naturally correspond to the factors that human judges consider responsible for a question remaining unanswered. This is one of the prime reasons why these quantities qualify as appropriate indicators of answerability.\nTo observe how the Part-of-Speech tags are distributed in the question texts, we define a diversity metric.",

        "evidence": "Sarcasm is defined as “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”. As the fields of affective computing and sentiment analysis have gained increasing popularity BIBREF0 , it is a major concern to detect sarcastic, ironic, and metaphoric expressions. Sarcasm, especially, is key for sentiment analysis as it can completely flip the polarity of opinions. Understanding the ground truth, or the facts about a given event, allows for the detection of contradiction between the objective polarity of the event (usually negative) and its sarcastic characteristic by the author (usually positive), as in “I love the pain of breakup”. Obtaining such knowledge is, however, very difficult.\nIn our experiments, we exposed the classifier to such knowledge extracted indirectly from Twitter. Namely, we used Twitter data crawled in a time period, which likely contain both the sarcastic and non-sarcastic accounts of an event or similar events. We believe that unambiguous non-sarcastic sentences provided the classifier with the ground-truth polarity of those events, which the classifier could then contrast with the opposite estimations in sarcastic sentences. Twitter is a more suitable resource for this purpose than blog posts, because the polarity of short tweets is easier to detect (as all the information necessary to detect polarity is likely to be contained in the same sentence) and because the Twitter API makes it easy to collect a large corpus of tweets containing both sarcastic and non-sarcastic examples of the same event.\nSometimes, however, just knowing the ground truth or simple facts on the topic is not enough, as the text may refer to other events in order to express sarcasm. For example, the sentence “If Hillary wins, she will surely be pleased to recall Monica each time she enters the Oval Office :P :D”, which refers to the 2016 US presidential election campaign and to the events of early 1990's related to the US president Clinton, is sarcastic because Hillary, a candidate and Clinton's wife, would in fact not be pleased to recall her husband's alleged past affair with Monica Lewinsky. The system, however, would need a considerable amount of facts, commonsense knowledge, anaphora resolution, and logical reasoning to draw such a conclusion. In this paper, we will not deal with such complex cases.\nExisting works on sarcasm detection have mainly focused on unigrams and the use of emoticons BIBREF1 , BIBREF2 , BIBREF3 , unsupervised pattern mining approach BIBREF4 , semi-supervised approach BIBREF5 and n-grams based approach BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 with sentiment features. Instead, we propose a framework that learns sarcasm features automatically from a sarcasm corpus using a convolutional neural network (CNN). We also investigate whether features extracted using the pre-trained sentiment, emotion and personality models can improve sarcasm detection performance. Our approach uses relatively lower dimensional feature vectors and outperforms the state of the art on different datasets. In summary, the main contributions of this paper are the following:\nThe rest of the paper is organized as follows: Section SECREF2 proposes a brief literature review on sarcasm detection; Section SECREF4 presents the proposed approach; experimental results and thorough discussion on the experiments are given in Section SECREF5 ; finally, Section SECREF6 concludes the paper.\nSarcasm is defined as “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”.",

        "question": "What are the different phases in systems development life cycle?",
        "evidence": "Systems development life cycle\n\nArticle\nTalk\nRead\nEdit\nView history\n\nTools\nFrom Wikipedia, the free encyclopedia\nThis article is about systems development life cycle. For the IBM's computer communication protocol, see Synchronous Data Link Control.\n\nModel of the software development life cycle, highlighting the maintenance phase\nIn systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. The SDLC concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation.\n\nOverview\nA systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems. Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates. Computer systems are complex and often link components with varying origins. Various SDLC methodologies have been created, such as waterfall, spiral, agile, rapid prototyping, incremental, and synchronize and stabilize.\n\nSDLC methodologies fit within a flexibility spectrum ranging from agile to iterative to sequential. Agile methodologies, such as XP and Scrum, focus on lightweight processes that allow for rapid changes. Iterative methodologies, such as Rational Unified Process and dynamic systems development method, focus on stabilizing project scope and iteratively expanding or improving products. Sequential or big-design-up-front (BDUF) models, such as waterfall, focus on complete and correct planning to guide larger projects and limit risks to successful and predictable results.[citation needed] Anamorphic development is guided by project scope and adaptive iterations.\n\nIn project management a project can include both a project life cycle (PLC) and an SDLC, during which somewhat different activities occur. According to Taylor (2004), \"the project life cycle encompasses all the activities of the project, while the systems development life cycle focuses on realizing the product requirements\".\n\nSDLC is not a methodology per se, but rather a description of the phases that a methodology should address. The list of phases is not definitive, but typically includes planning, analysis, design, build, test, implement, and maintenance/support. In the Scrum framework, for example, one could say a single user story goes through all the phases of the SDLC within a two-week sprint. By contrast the waterfall methodology, where every business requirement[citation needed] is translated into feature/functional descriptions which are then all implemented typically over a period of months or longer.[citation needed]\n\nHistory\nAccording to Elliott & Strachan & Radford (2004), SDLC \"originated in the 1960s, to develop large scale functional business systems in an age of large scale business conglomerates. Information systems activities revolved around heavy data processing and number crunching routines\".\n\nThe structured systems analysis and design method (SSADM) was produced for the UK government Office of Government Commerce in the 1980s. Ever since, according to Elliott (2004), \"the traditional life cycle approaches to systems development have been increasingly replaced with alternative approaches and frameworks, which attempted to overcome some of the inherent deficiencies of the traditional SDLC\".\n\nModels\n\nA ten-phase version of the systems development life cycle\nSDLC provides a set of phases/steps/activities for system designers and developers to follow. Each phase builds on the results of the previous one. Not every project requires that the phases be sequential. For smaller, simpler projects, phases may be combined/overlap.\n\nWaterfall\nThe oldest and best known is the waterfall model, which uses a linear sequence of steps. Waterfall has different varieties. One variety is as follows:\n\nPreliminary analysis\nConduct with a preliminary analysis, consider alternative solutions, estimate costs and benefits, and submit a preliminary plan with recommendations.\n\nConduct preliminary analysis: Identify the organization's objectives and define the nature and scope of the project. Ensure that the project fits with the objectives.\nConsider alternative solutions: Alternatives may come from interviewing employees, clients, suppliers, and consultants, as well as competitive analysis.\nCost-benefit analysis: Analyze the costs and benefits of the project.\nSystems analysis, requirements definition\nDecompose project goals[clarification needed] into defined functions and operations. This involves gathering and interpreting facts, diagnosing problems, and recommending changes. Analyze end-user information needs and resolve inconsistencies and incompleteness:\n\nCollect facts: Obtain end-user requirements by document review, client interviews, observation, and questionnaires.\nScrutinize existing system(s): Identify pros and cons.\nAnalyze the proposed system: Find solutions to issues and prepare specifications, incorporating appropriate user proposals.\nSystems design\nAt this step, desired features and operations are detailed, including screen layouts, business rules, process diagrams, pseudocode, and other deliverables.\n\nDevelopment\nWrite the code.\n\nIntegration and testing\nAssemble the modules in a testing environment. Check for errors, bugs, and interoperability.\n\nAcceptance, installation, deployment\nPut the system into production. This may involve training users, deploying hardware, and loading information from the prior system.\n\nMaintenance\nMonitor the system to assess its ongoing fitness. Make modest changes and fixes as needed.\n\nEvaluation\nThe system and the process are reviewed. Relevant questions include whether the newly implemented system meets requirements and achieves project goals, whether the system is usable, reliable/available, properly scaled and fault-tolerant. Process checks include review of timelines and expenses, as well as user acceptance.\n\nDisposal\nAt end of life, plans are developed for discontinuing the system and transitioning to its replacement. Related information and infrastructure must be repurposed, archived, discarded, or destroyed, while appropriately protecting security.\n\nIn the following diagram, these stages of the are divided into ten steps, from definition to creation and modification of IT work products:\n\nSystems analysis and design\nSystems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem. SAD can help balance competing high-level requirements. SAD interacts with distributed enterprise architecture, enterprise I.T. Architecture, and business architecture, and relies heavily on concepts such as partitioning, interfaces, personae and roles, and deployment/operational modeling to arrive at a high-level system description. This high-level description is then broken down into the components and modules which can be analyzed, designed, and constructed separately and integrated to accomplish the business goal. SDLC and SAD are cornerstones of full life cycle product and system planning.\n\nObject-oriented analysis and design\nObject-oriented analysis and design (OOAD) is the process of analyzing a problem domain to develop a conceptual model that can then be used to guide development. During the analysis phase, a programmer develops written requirements and a formal vision document via interviews with stakeholders.\n\nThe conceptual model that results from OOAD typically consists of use cases, and class and interaction diagrams. It may also include a user interface mock-up.\n\nAn output artifact does not need to be completely defined to serve as input of object-oriented design; analysis and design may occur in parallel. In practice the results of one activity can feed the other in an iterative process.\n\nSome typical input artifacts for OOAD:\n\nConceptual model: A conceptual model is the result of object-oriented analysis. It captures concepts in the problem domain. The conceptual model is explicitly independent of implementation details.\nUse cases: A use case is a description of sequences of events that, taken together, complete a required task. Each use case provides scenarios that convey how the system should interact with actors (users). Actors may be end users or other systems. Use cases may further elaborated using diagrams. Such diagrams identify the actor and the processes they perform.\nSystem Sequence Diagram: A System Sequence diagrams (SSD) is a picture that shows, for a particular use case, the events that actors generate, their order, including inter-system events.\nUser interface document: Document that shows and describes the user interface.\nData model: A data model describes how data elements relate to each other. The data model is created before the design phase. Object-oriented designs map directly from the data model. Relational designs are more involved.\nSystem lifecycle\nThe system lifecycle is a view of a system or proposed system that addresses all phases of its existence to include system conception, design and development, production and/or construction, distribution, operation, maintenance and support, retirement, phase-out, and disposal.\n\nConceptual design\nThe conceptual design stage is the stage where an identified need is examined, requirements for potential solutions are defined, potential solutions are evaluated, and a system specification is developed. The system specification represents the technical requirements that will provide overall guidance for system design. Because this document determines all future development, the stage cannot be completed until a conceptual design review has determined that the system specification properly addresses the motivating need.\n\nKey steps within the conceptual design stage include:\n\nNeed identification\nFeasibility analysis\nSystem requirements analysis\nSystem specification\nConceptual design review\nPreliminary system design\nDuring this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification. Interfaces between subsystems are defined, as well as overall test and evaluation requirements. At the completion of this stage, a development specification is produced that is sufficient to perform detailed design and development.\n\nKey steps within the preliminary design stage include:\n\nFunctional analysis\nRequirements allocation\nDetailed trade-off studies\nSynthesis of system options\nPreliminary design of engineering models\nDevelopment specification\nPreliminary design review\nFor example, as the system analyst of Viti Bank, you have been tasked to examine the current information system. Viti Bank is a fast-growing bank in Fiji. Customers in remote rural areas are finding difficulty to access the bank services. It takes them days or even weeks to travel to a location to access the bank services. With the vision of meeting the customers' needs, the bank has requested your services to examine the current system and to come up with solutions or recommendations of how the current system can be provided to meet its needs.\n\nDetail design and development\nThis stage includes the development of detailed designs that brings initial design work into a completed form of specifications. This work includes the specification of interfaces between the system and its intended environment, and a comprehensive evaluation of the systems logistical, maintenance and support requirements. The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification.\n\nKey steps within the detail design and development stage include:\n\nDetailed design\nDetailed synthesis\nDevelopment of engineering and prototype models\nRevision of development specification\nProduct, process, and material specification\nCritical design review\nProduction and construction\nDuring the production and/or construction stage the product is built or assembled in accordance with the requirements specified in the product, process and material specifications, and is deployed and tested within the operational target environment. System assessments are conducted in order to correct deficiencies and adapt the system for continued improvement.\n\nKey steps within the product construction stage include:\n\nProduction and/or construction of system components\nAcceptance testing\nSystem distribution and operation\nOperational testing and evaluation\nSystem assessment\nUtilization and support\nOnce fully deployed, the system is used for its intended operational role and maintained within its operational environment.\n\nKey steps within the utilization and support stage include:\n\nSystem operation in the user environment\nChange management\nSystem modifications for improvement\nSystem assessment\nPhase-out and disposal\nEffectiveness and efficiency of the system must be continuously evaluated to determine when the product has met its maximum effective lifecycle. Considerations include: Continued existence of operational need, matching between operational requirements and system performance, feasibility of system phase-out versus maintenance, and availability of alternative systems.\n\nPhases\n\nThis section includes a list of references, related reading, or external links, but its sources remain unclear because it lacks inline citations. Please help to improve this section by introducing more precise citations. (January 2023) (Learn how and when to remove this template message)\nSystem investigation\nDuring this step, current priorities that would be affected and how they should be handled are considered. A feasibility study determines whether creating a new or improved system is appropriate. This helps to estimate costs, benefits, resource requirements, and specific user needs.\n\nThe feasibility study should address operational, financial, technical, human factors, and legal/political concerns.\n\nAnalysis\nThe goal of analysis is to determine where the problem is. This step involves decomposing the system into pieces, analyzing project goals, breaking down what needs to be created, and engaging users to define requirements.\n\nDesign\nIn systems design, functions and operations are described in detail, including screen layouts, business rules, process diagrams, and other documentation. Modular design reduces complexity and allows the outputs to describe the system as a collection of subsystems.\n\nThe design stage takes as its input the requirements already defined. For each requirement, a set of design elements is produced.\n\nDesign documents typically include functional hierarchy diagrams, screen layouts, business rules, process diagrams, pseudo-code, and a complete data model with a data dictionary. These elements describe the system in sufficient detail that developers and engineers can develop and deliver the system with minimal additional input.\n\nTesting\nThe code is tested at various levels in software testing. Unit, system, and user acceptance tests are typically performed. Many approaches to testing have been adopted.\n\nThe following types of testing may be relevant:\n\nPath testing\nData set testing\nUnit testing\nSystem testing\nIntegration testing\nBlack-box testing\nWhite-box testing\nRegression testing\nAutomation testing\nUser acceptance testing\nSoftware performance testing\nTraining and transition\nOnce a system has been stabilized through testing, SDLC ensures that proper training is prepared and performed before transitioning the system to support staff and end users. Training usually covers operational training for support staff as well as end-user training.\n\nAfter training, systems engineers and developers transition the system to its production environment.\n\nOperations and maintenance\nMaintenance includes changes, fixes, and enhancements.\n\nEvaluation\nThe final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements.\n\nLife cycle\nManagement and control\n\nSDLC phases related to management controls\nSDLC phase objectives are described in this section with key deliverables, a description of recommended tasks, and a summary of related control objectives for effective management. It is critical for the project manager to establish and monitor control objectives while executing projects. Control objectives are clear statements of the desired result or purpose and should be defined and monitored throughout a project. Control objectives can be grouped into major categories (domains), and relate to the SDLC phases as shown in the figure.\n\nTo manage and control a substantial SDLC initiative, a work breakdown structure (WBS) captures and schedules the work. The WBS and all programmatic material should be kept in the \"project description\" section of the project notebook.[clarification needed] The project manager chooses a WBS format that best describes the project.\n\nThe diagram shows that coverage spans numerous phases of the SDLC but the associated MCD[clarification needed] shows mappings to SDLC phases. For example, Analysis and Design is primarily performed as part of the Acquisition and Implementation Domain, and System Build and Prototype is primarily performed as part of delivery and support.\n\nWork breakdown structured organization\n\nWork breakdown structure\nThe upper section of the WBS provides an overview of the project scope and timeline. It should also summarize the major phases and milestones. The middle section is based on the SDLC phases. WBS elements consist of milestones and tasks to be completed rather than activities to be undertaken and have a deadline. Each task has a measurable output (e.g., analysis document). A WBS task may rely on one or more activities (e.g. coding). Parts of the project needing support from contractors should have a statement of work (SOW). The development of a SOW does not occur during a specific phase of SDLC but is developed to include the work from the SDLC process that may be conducted by contractors.\n\nBaselines\nBaselines[clarification needed] are established after four of the five phases of the SDLC, and are critical to the iterative nature of the model. Baselines become milestones.\n\nfunctional baseline: established after the conceptual design phase.\nallocated baseline: established after the preliminary design phase.\nproduct baseline: established after the detail design and development phase.\nupdated product baseline: established after the production construction phase.",

        "question": "What is a genome-wide association study (GWAS)?",
        "evidence": "",
        "answer": "In genomics, a genome-wide association study (GWA study, or GWAS), is an observational study of a genome-wide set of genetic variants in different individuals to see if any variant is associated with a trait. GWA studies typically focus on associations between single-nucleotide polymorphisms (SNPs) and traits like major human diseases, but can equally be applied to any other genetic variants and any other organisms.\n\nWhen applied to human data, GWA studies compare the DNA of participants having varying phenotypes for a particular trait or disease. These participants may be people with a disease (cases) and similar people without the disease (controls), or they may be people with different phenotypes for a particular trait, for example blood pressure. This approach is known as phenotype-first, in which the participants are classified first by their clinical manifestation(s), as opposed to genotype-first. Each person gives a sample of DNA, from which millions of genetic variants are read using SNP arrays. If there is significant statistical evidence that one type of the variant (one allele) is more frequent in people with the disease, the variant is said to be associated with the disease. The associated SNPs are then considered to mark a region of the human genome that may influence the risk of disease.\n\nGWA studies investigate the entire genome, in contrast to methods that specifically test a small number of pre-specified genetic regions. Hence, GWAS is a non-candidate-driven approach, in contrast to gene-specific candidate-driven studies. GWA studies identify SNPs and other variants in DNA associated with a disease, but they cannot on their own specify which genes are causal.\n\nThe first successful GWAS published in 2002 studied myocardial infarction. This study design was then implemented in the landmark GWA 2005 study investigating patients with age-related macular degeneration, and found two SNPs with significantly altered allele frequency compared to healthy controls. As of 2017, over 3,000 human GWA studies have examined over 1,800 diseases and traits, and thousands of SNP associations have been found. Except in the case of rare genetic diseases, these associations are very weak, but while they may not explain much of the risk, they provide insight into genes and pathways that can be important.",

        "answer": "CapsGNN extracts multi-scale node features from different convolutional layers and represents the extracted features in the form of capsules. Compared to classic GCN models, CapsGNN has been proven to have better representation ability on graph data. Nevertheless, CapsGNN is sensitive to changes in depth and width just because of the vectorized graph representation in it, as shown in Figure 1. Therefore, based on CapsGNN, we propose an RL-based assistant module (AM) to find optimal depth-width settings on different datasets. Note that we also added an experiment on the effectiveness of AM on GIN, the model with the best classification performance in all the baseline methods, and recorded corresponding accuracy results in Table 3.",
        "evidence": "Image restoration algorithms aim to recover a high-quality image from a contaminated input image by solving an ill-posed image restoration problem. There are various image restoration tasks depending on the type of corruptions, such as image denoising, demosaicing, single image super-resolution, and image compression artifacts reduction. To restore corrupted information from the contaminated image, a variety of image priors were proposed.\nRecently, image restoration methods based on deep neural networks have achieved great success. Inspired by the widely used non-local prior, most recent approaches based on neural networks adapt non-local attention into their neural network to enhance the representation learning, following the non-local neural networks. In a nonlocal block, a response is calculated as a weighted sum over all pixel-wise features on the feature map to account for long-range information. Such a module was initially designed for high-level recognition tasks such as image classification, and it has been proven to be beneficial for low-level vision tasks.\nThough attention modules have been shown to be effective in boosting the performance. Most attention modules only explore the correlation among features at the same layer. Actually, features at different intermediate layers encode variant information at different scales, and might be helpful to augment the information used in recovering the high-quality image. Motivated by the potential benefit of exploring feature correlation across intermediate layers, Holistic Attention Network (HAN) is proposed to find interrelationship among features at hierarchical levels with a Layer Attention Module (LAM). However, LAM assigns a single importance weight to all features at the same layer and neglects the difference of spatial positions of these features. Recent research in omnidirectional representation suggests that exploring the relationship among features at different layers can benefit the representation learning of neural networks. Nevertheless, calculating correlation among features at hierarchical layers is computationally expensive due to the quadratic complexity of dot product attention. The complexity of such cross-layer attention design is increased from (HW ) 2 L to (HW L) 2 , where H, W are the height and width of the feature map and L is the number of layers.\n1.1 CONTRIBUTIONS Our contributions are listed as follows.\nFirst, in order to address the problem caused by only referring to keys within the same layer in most attention modules, we propose a novel attention module termed Cross-Layer Attention (CLA), which searches for keys across different layers for each query feature. With the help of the deformation mechanism, CLA only attends to a small set of keys at different layers for each query feature.\nSecond, we propose an improved CLA termed Adaptive Cross-Layer Attention (ACLA) which selects an adaptive number of keys at each layer for each query, and searches for the optimal insert positions of ACLA modules. We deploy ACLA modules on commonly used neural network models, e.g. EDSR, for image restoration. Extensive experiments on single image super-resolution, image denoising, image compression artifacts reduction, and image demosaicing demonstrate the effectiveness of our approach.\nTo evaluate the effects of the depth and width in CapsGNN, we change them to observe the performance of the model on two graph datasets, ENZYMES and IMDB-MULTI (Kersting et al., 2016), in bioinformatics and social fields, respectively. It is shown in Figure 1 that if the model has small D and W, it can not sufficiently extract the features of graphs. On the contrary, when the model structure is too complicated, overfitting occurs frequently. Thus, CapsGNN is sensitive to changes in depth and width just because of the vectorized graph representation in it. Since the impacts of D\nand W are distinct on different datasets, it is necessary to adaptively adjust the model architecture according to the latent characteristics of particular workloads. Figure 1: Results of classification accuracy when increasing D and W. The third subfigure depicts the changes of both D and W, and the x-axis represents the increase of either of them (for simplicity, the growth scales of D and W are set the same here).",

In recent years, the morphology of words is drawing more and more attention BIBREF2 , especially for Chinese whose writing system is based on logograms.\nUTF8gbsn With the gradual exploration of the semantic features of Chinese, scholars have found that not only words and characters are important semantic carriers, but also stroke feature of Chinese characters is crucial for inferring semantics BIBREF3 . Actually, a Chinese word usually consists of several characters, and each character can be further decomposed into a stroke sequence which is certain and changeless, and this kind of stroke sequence is very similar to the construction of English words. In Chinese, a particular sequence of strokes can reflect the inherent semantics. As shown in the upper half of Figure FIGREF3 , the Chinese character “驾\" (drive) can be decomposed into a sequence of eight strokes, where the last three strokes together correspond to a root character “马\" (horse) similar to the root “clar\" of English word “declare\" and “clarify\".\nMoreover, Chinese is a language originated from Oracle Bone Inscriptions (a kind of hieroglyphics). Its character glyphs have a spatial structure similar to graphs which can convey abundant semantics BIBREF4 . Additionally, the critical reason why Chinese characters are so rich in morphological information is that they are composed of basic strokes in a 2-D spatial order. However, different spatial configurations of strokes may lead to different semantics. As shown in the lower half of Figure 1, three Chinese characters “入\" (enter), “八\" (eight) and “人\" (man) share exactly a common stroke sequence, but they have completely different semantics because of their different spatial configurations.\nIn addition, some biological investigations have confirmed that there are actually two processing channels for Chinese language. Specifically, Chinese readers not only activate the left brain which is a dominant hemisphere in processing alphabetic languages BIBREF5 , BIBREF6 , BIBREF7 , but also activate the areas of the right brain that are responsible for image processing and spatial information at the same time BIBREF8 . Therefore, we argue that the morphological information of characters in Chinese consists of two parts, i.e., the sequential information hidden in root-like strokes order, and the spatial information hidden in graph-like character glyphs. Along this line, we propose a novel Dual-channel Word Embedding (DWE) model for Chinese to realize the joint learning of sequential and spatial information in characters. Finally, we evaluate DWE on two representative tasks, where the experimental results exactly validate the superiority of DWE in capturing the morphological information of Chinese.\nFinally, we evaluate DWE on two representative tasks, where the experimental results exactly validate the superiority of DWE in capturing the morphological information of Chinese.",

Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nIn particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.",

        "evidence": "Consider the task of translating from an extremely low-resource language (source) to a target language. The parallel corpus between the two languages if available may be too small to train a NMT model. Similar to existing works BIBREF3 , BIBREF10 , BIBREF12 , we use transfer learning to overcome data sparsity and train a NMT model between the source and the target languages. Specifically, the NMT model (parent model) is trained on the assisting language and target language pairs. We choose English as the assisting language in all our experiments. In our resource-scarce scenario, we have no parallel corpus for the child task. Hence, at test time, the source language sentence is translated using the parent model after performing a word-by-word translation into the assisting language.\nSince the source language and the assisting language (English) have different word order, we hypothesize that it leads to inconsistencies in the contextual representations generated by the encoder for the two languages. In this paper, we propose to pre-order English sentences (assisting language sentences) to match the word-order of the source language and train the parent model on this pre-ordered corpus. In our experiments, we look at scenarios where the assisting language has SVO word order and the source language has SOV word order.\nFor instance, consider the English sentence Anurag will meet Thakur. One of the pre-ordering rule swaps the position of the noun phrase followed by a transitive verb with the transitive verb. The original and the resulting re-ordered parse tree will be as shown in the Table TABREF5 . Applying this reordering rule to the above sentence Anurag will meet Thakur will yield the reordered sentence Anurag Thakur will meet. Additionally, the Table TABREF5 shows the parse trees for the above sentence with and without pre-ordering.\nPre-ordering should also be beneficial for other word order divergence scenarios (e.g., SOV to SVO), but we leave verification of these additional scenarios for future work.\nSince the source language and the assisting language (English) have different word order, we hypothesize that it leads to inconsistencies in the con textual representations generated by the encoder for the two languages.",

        "question": "What learning architecture is proposed in the paper?",
        "answer": "A supervised learning architecture for text classification in terms of hateful content.",
        "evidence": "Social media is a very popular way for people to express their opinions publicly and to interact with others online. In aggregation, social media can provide a reflection of public sentiment on various events. Unfortunately, many users engaging online, either on social media, forums or blogs, will often have the risk of being targeted or harassed via abusive language, which may severely impact their online experience and the community in general. The existence of social networking services creates the need for detecting user-generated hateful messages prior to publication. All published text that is used to express hatred towards some particular group with the intention to humiliate its members is considered a hateful message.\nAlthough hate speech is protected under the free speech provisions in the United States, there are other countries, such as Canada, France, United Kingdom, and Germany, where there are laws prohibiting it as being promoting violence or social disorder. Social media services such as Facebook and Twitter have been criticized for not having done enough to prohibit the use of their services for attacking people belonging to some specific race, minority etc. BIBREF0 . They have announced though that they would seek to battle against racism and xenophobia BIBREF1 . Nevertheless, the current solutions deployed by them have attempted to address the problem with manual effort, relying on users to report offensive comments BIBREF2 . This not only requires a huge effort by human annotators, but it also has the risk of applying discrimination under subjective judgment. Moreover, a non-automated task by human annotators would have strong impact on system response times, since a computer-based solution can accomplish this task much faster than humans. The massive rise in the user-generated content in the above social media services, with manual filtering not being scalable, highlights the need for automating the process of on-line hate-speech detection.\nDespite the fact that the majority of the solutions for automated detection of offensive text rely on Natural Language Processing (NLP) approaches, there is lately a tendency towards employing pure machine learning techniques like neural networks for that task. NLP approaches have the drawback of being complex, and to a large extent dependent on the language used in the text. This provides a strong motivation for employing alternative machine learning models for the classification task. Moreover, the majority of the existing automated approaches depend on using pre-trained vectors (e.g. Glove, Word2Vec) as word embeddings to achieve good performance from the classification model. That makes the detection of hatred content unfeasible in cases where users have deliberately obfuscated their offensive terms with short slang words.\nThere is a plethora of unsupervised learning models in the existing literature to deal with hate-speech BIBREF3 , as well as in detecting the sentiment polarity in tweets BIBREF4 . At the same time, the supervised learning approaches have not been explored adequately so far. While the task of sentence classification seems similar to that of sentiment analysis; nevertheless, in hate-speech even negative sentiment could still provide useful insight. Our intuition is that the task of hate-speech detection can be further benefited by the incorporation of other sources of information to be used as features into a supervised learning model. A simple statistical analysis on an existing annotated dataset of tweets by BIBREF5 , can easily reveal the existence of significant correlation between the user tendency in expressing opinions that belong to some offensive class (Racism or Sexism), and the annotation labels associated with that class. More precisely, the correlation coefficient value that describes such user tendency was found to be 0.71 for racism in the above dataset, while that value reached as high as 0.76 for sexism. In our opinion, utilizing such user-oriented behavioural data for reinforcing an existing solution is feasible, because such information is retrieva2ble in real-world use-case scenarios like Twitter. This highlights the need to explore the user features more systematically to further improve the classification accuracy of a supervised learning system.\nOur approach employs a neural network solution composed of multiple Long-Short-Term-Memory (LSTM) based classifiers, and utilizes user behavioral characteristics such as the tendency towards racism or sexism to boost performance. Although our technique is not necessarily revolutionary in terms of the deep learning models used, we show in this paper that it is quite effective.\nOur main contributions are: INLINEFORM0 ) a deep learning architecture for text classification in terms of hateful content, which incorporates features derived form the users' behavioural data, INLINEFORM1 ) a language agnostic solution, due to no-use of pre-trained word embeddings, for detecting hate-speech, INLINEFORM2 ) an experimental evaluation of the model on a Twitter dataset, demonstrating the top performance achieved on the classification task. Special focus is given to investigating how the additional features concerning the users' tendency to utter hate-speech, as expressed by their previous history, could leverage the performance. To the best of our knowledge, there has not been done any previous study on exploring features related to the users tendency in hatred content that used a deep learning model.\nThe rest of the paper is organized as follows. In Section SECREF2 we describe the problem of hate speech in more detail, and we refer to the existing work in the field in Section SECREF3 . In Section SECREF4 we present our proposed model, while in Section SECREF5 we refer to the dataset used, the evaluation tests we performed and we discuss the results received.

Valdivia, Chile 22 May 1960 (magnitude 9.5)\nThis earthquake killed 1655 people, injured 3000 and displaced two million. It caused US$550 million damage in Chile, while the tsunami that it spawned caused deaths and damage as far away as Hawaii, Japan and the Philippines. The 'rupture zone' of the quake was more than 1000 km long. Two days after the initial quake, the nearby volcano Puyehue erupted, sending ash and steam up to 6 km into the atmosphere over a period of several weeks.\n\n2. Prince William Sound, Alaska 28 March 1964 (magnitude 9.2)\nCompared to the Chilean earthquake, this earthquake was less damaging: the resulting tsunami took 128 lives and caused overall US$311 million in damage. The earthquake was felt mainly over Alaska, as well as some places in Canada, while the tsunami created by it caused damage as far away as Hawaii. The most damage was sustained by the city of Anchorage, 120 km north-west of the epicentre. Shaking from the quake itself is reported to have lasted for three minutes.\n\n3. Sumatra, Indonesia 26 December 2004 (magnitude 9.1)\nIn terms of damage and loss of life, the scale of the disaster caused by the resulting Boxing Day Tsunami was enormous. In total, 227,900 people were killed or presumed dead, with around 1.7 million displaced over 14 countries in South Asia and East Africa. The epicentre was 250 km south-east of Band Aceh, Indonesia, at a depth of 30 km. Several days later on 28 December, a mud volcano began erupting near Baratang, Andamar Islands, which is thought to have been associated with the earthquake.\n\n4. Sendai, Japan 11 March 2011 (magnitude 9.0)\nSo far the official death toll stands at several thousand from the combined effect of the powerful earthquake, aftershocks and the tsunami. However, the total is expected to rise, with some estimates of a final toll of over 10,000. Economic impacts are expected to be huge, with the shutting down of nuclear reactors which many industries rely on for power.\n\n5. Kamchatka, Russia 4 November 1952 (magnitude 9.0)\nThis earthquake generated a tsunami that caused widespread damage in the Hawaiian Islands. Property damage was estimated at around US$1,000,000. Some reports describe waves of over 9 m high at Kaena Point, Oahu. A farmer on Oahu reported the loss of six cows to the tsunami, but no people were reported killed.\n\n6. Bio-bio, Chile 27 February 2010 (magnitude 8.8)\nThis earthquake and subsequent tsunami killed at least 521 people, with 56 missing and 12,000 injured. More than 800,000 people were displaced with a total of 1.8m people affected across Chile, where damage was estimated at US$30 billion. The epicentre was 335 km south-west of Santiago, at a depth of 35 km. A minor tsunami travelled across the Pacific causing damage to boats as far away as San Diego, California.\n\n7. Off the coast of Ecuador 31 January 1906 (magnitude 8.8)\nThis earthquake caused a tsunami that is reported to have killed between 500 and 1,500 in Ecuador and Colombia. The tsunami travelled as far north as San Francisco, on the west coast of the US, and west to Hawaii and Japan. The tsunami took roughly 12 hours to cross the Pacific to Hilo, Hawaii.\n\n8. Rat Islands, Alaska 2 April 1965 (magnitude 8.7)\nThe worst of the damage attributed to this earthquake was caused by a tsunami, reported to be about 10 m high on Shemya Island. The wave caused flooding on Amchitka Island, causing US$10,000 in property damage. No deaths or injuries were reported.\n\n9. Sumatra, Indonesia 28 March 2005 (magnitude 8.6)\nThis earthquake killed 1313, with over 400 people injured by the tsunami as far away as Sri Lanka. The epicentre was 205 km north-west of Sibolga, Sumatra, at a depth of 30 km. This region, also the site of the 2004 Boxing Day Tsunami, is particularly geologically active, with three of the 15 biggest known earthquakes having happened here.\n\n10. Assam - Tibet 15 August 1950 (magnitude 8.6)\nThis inland earthquake caused widespread damages to buildings as well as large landslides. 780 people were killed in eastern Tibet, with many villages and towns affected across Assam, China, Tibet and India. Oscillations to lake levels occurred as far away as Norway. The total death toll is likely to be higher, as no definitive total was ever estimated.

        "evidence": "Figure 1 presents architecture of the WSD system. As one may observe, no human labor is used to learn interpretable sense representations and the corresponding disambiguation models. Instead, these are induced from the input text corpus using the JoBimText approach BIBREF8 implemented using the Apache Spark framework, enabling seamless processing of large text collections. Induction of a WSD model consists of several steps. First, a graph of semantically related words, i.e. a distributional thesaurus, is extracted. Second, word senses are induced by clustering of an ego-network of related words BIBREF9 . Each discovered word sense is represented as a cluster of words. Next, the induced sense inventory is used as a pivot to generate sense representations by aggregation of the context clues of cluster words. To improve interpretability of the sense clusters they are labeled with hypernyms, which are in turn extracted from the input corpus using Hearst:92 patterns. Finally, the obtained WSD model is used to retrieve a list of sentences that characterize each sense. Sentences that mention a given word are disambiguated and then ranked by prediction confidence. Top sentences are used as sense usage examples. For more details about the model induction process refer to BIBREF10 . Currently, the following WSD models induced from a text corpus are available: Word senses based on cluster word features.

Path–based similarity measures use the structure of a taxonomy to measure similarity – concepts positioned close to each other are more similar than those further apart. Feature–based methods rely on set theoretic measures of overlap between features (union and intersection). The information content measures quantify the amount of information that a concept provides – more specific concepts have a higher amount of information content.\nRadaMBB89 introduce the Conceptual Distance measure. This measure is simply the length of the shortest path between two concepts ( INLINEFORM0 and INLINEFORM1 ) in the MeSH hierarchy. Paths are based on broader than (RB) and narrower than (RN) relations. CaviedesC04 extends this measure to use parent (PAR) and child (CHD) relations. Our INLINEFORM2 measure is simply the reciprocal of this shortest path value (Equation EQREF3 ), so that larger values (approaching 1) indicate a high degree of similarity. DISPLAYFORM0 \nWhile the simplicity of INLINEFORM0 is appealing, it can be misleading when concepts are at different levels of specificity. Two very general concepts may have the same path length as two very specific concepts. WuP94 introduce a correction to INLINEFORM1 that incorporates the depth of the concepts, and the depth of their Least Common Subsumer (LCS). This is the most specific ancestor two concepts share. In this measure, similarity is twice the depth of the two concept's LCS divided by the product of the depths of the individual concepts (Equation EQREF4 ). Note that if there are multiple LCSs for a pair of concepts, the deepest of them is used in this measure. DISPLAYFORM0 \nZhongZLY02 take a very similar approach and again scale the depth of the LCS by the sum of the depths of the two concepts (Equation EQREF5 ), where INLINEFORM0 . The value of INLINEFORM1 was set to 2 based on their recommendations. DISPLAYFORM0 \nPekarS02 offer another variation on INLINEFORM0 , where the shortest path of the two concepts to the LCS is used, in addition to the shortest bath between the LCS and the root of the taxonomy (Equation EQREF6 ). DISPLAYFORM0 \nFeature–based methods represent each concept as a set of features and then measure the overlap or sharing of features to measure similarity. In particular, each concept is represented as the set of their ancestors, and similarity is a ratio of the intersection and union of these features.\nMaedcheS01 quantify the similarity between two concepts as the ratio of the intersection over their union as shown in Equation EQREF8 . DISPLAYFORM0 \nBatetSV11 extend this by excluding any shared features (in the numerator) as shown in Equation EQREF9 . DISPLAYFORM0 \nInformation content is formally defined as the negative log of the probability of a concept. The effect of this is to assign rare (low probability) concepts a high measure of information content, since the underlying assumption is that more specific concepts are less frequently used than more common ones.\nResnik95 modified this notion of information content in order to use it as a similarity measure. He defines the similarity of two concepts to be the information content of their LCS (Equation EQREF11 ). DISPLAYFORM0 \nJiangC97, Lin98, and PirroE10 extend INLINEFORM0 by incorporating the information content of the individual concepts in various different ways. Lin98 defines the similarity between two concepts as the ratio of information content of the LCS with the sum of the individual concept's information content (Equation EQREF12 ). Note that INLINEFORM1 has the same form as INLINEFORM2 and INLINEFORM3 , and is in effect using information content as a measure of specificity (rather than depth). If there is more than one possible LCS, the LCS with the greatest IC is chosen. DISPLAYFORM0 \nJiangC97 define the distance between two concepts to be the sum of the information content of the two concepts minus twice the information content of the concepts' LCS. We modify this from a distance to a similarity measure by taking the reciprocal of the distance (Equation EQREF13 ). Note that the denominator of INLINEFORM0 is very similar to the numerator of INLINEFORM1 . DISPLAYFORM0 \nPirroE10 define the similarity between two concepts as the information content of the two concept's LCS divided by the sum of their individual information content values minus the information content of their LCS (Equation EQREF14 ). Note that INLINEFORM0 can be viewed as a set–theoretic version of INLINEFORM1 . DISPLAYFORM0 \nFeature–based methods rely on set theoretic measures of overlap between features (union and intersection).",

BIBREF0 Detecting, assessing, and preventing these events are the tasks of pharmacovigilance. In the pre-trial and trial stages of drug development, the number of people taking a drug is carefully controlled, and the collection of ADR data is centralized. However, after the drug is available widely, post-marketing surveillance often requires the collection and merging of data from disparate sources, BIBREF1 including patient-initiated spontaneous reporting. Unfortunately, adverse reactions to drugs are grossly underreported to health professionals. BIBREF2 , BIBREF3 Considerable issues with patient-initiated reporting have been identified, including various types of reporting biases and causal attributions of adverse events. BIBREF4 , BIBREF5 , BIBREF6 Nevertheless, a large number of people, freely and spontaneously, report ADRs on social media. The potential availability of inexpensive, large-scale, and real-time data on ADRs makes social media a valuable resource for pharmacovigilance.\nInformation required for pharmacovigilance includes a reported adverse drug reaction, a linked drug referred to by its full, abbreviated, or generic name, and an indication whether it was the social media post author that experienced the adverse event. However, there are considerable challenges in automatically extracting this information from free-text social media data. Social media texts are often short and informal, and include non-standard abbreviations and creative language. Drug names or their effects may be mis-spelled; they may be used metaphorically (e.g., Physics is like higher level maths on steroids). Drug names might have other non-drug related meanings (e.g., ecstasy). An adverse event may be negated or only expected (e.g., I bet I'll be running to the bathroom all night), or it may not apply to the author of the post at all (e.g., a re-tweet of a press release).\nThe shared task challenge organized as part of the AMIA-2017 Workshop on Social Media Mining for Health Applications (SMM4H) focused on Twitter data and had three tasks: Task 1 - recognizing whether a tweet is reporting an adverse drug reaction, Task 2 - inferring whether a tweet is reporting the intake of a medication by the tweeter, and Task 3 - mapping a free-text ADR to a standardized MEDDRA term. Our team made submissions for Task 1 and Task 2. For both tasks, we trained Support Vector Machine classifiers using a variety of surface-form, sentiment, and domain-specific features. Handling class imbalance with under-sampling was particularly helpful. Our submissions obtained F-scores of 0.435 on Task 1 and 0.673 on Task 2, resulting in a rank of first and third, respectively.

Binary search compares the target value to the middle element of the array. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again taking the middle element to compare to the target value, and repeating this until the target value is found. If the search ends with the remaining half being empty, the target is not in the array.\n\nThe binary search runs in logarithmic time in the worst case, making \n\nO(log n) comparisons, where \n\nn is the number of elements in the array. Binary search is faster than linear search except for small arrays. However, the array must be sorted first to apply binary search. There are specialized data structures designed for fast searching, such as hash tables, that can be searched more efficiently than binary search. However, binary search can solve a wider range of problems, such as finding the next-smallest or next-largest element in the array relative to the target even if it is absent from the array.\n\nThere are numerous variations of binary search. In particular, fractional cascading speeds up binary searches for the same value in multiple arrays. Fractional cascading efficiently solves several search problems in computational geometry and numerous other fields. Exponential search extends binary search to unbounded lists. The binary search tree and B-tree data structures are based on binary search.",

While this method allows for customizing the model to the particulars of each language and the available data, it also presents a problem when little data is available: extensive language-specific annotation is required. The reality is that most languages have very little annotated data for most NLP tasks.\nammar2016malopa found that using training data from multiple languages annotated with Universal Dependencies BIBREF1 , and represented using multilingual word vectors, outperformed monolingual training. Inspired by this, we apply the idea of training one model on multiple languages—which we call polyglot training—to PropBank-style semantic role labeling (SRL). We train several parsers for each language in the CoNLL 2009 dataset BIBREF0 : a traditional monolingual version, and variants which additionally incorporate supervision from English portion of the dataset. To our knowledge, this is the first multilingual SRL approach to combine supervision from several languages.\nThe CoNLL 2009 dataset includes seven different languages, allowing study of trends across the same. Unlike the Universal Dependencies dataset, however, the semantic label spaces are entirely language-specific, making our task more challenging. Nonetheless, the success of polyglot training in this setting demonstrates that sharing of statistical strength across languages does not depend on explicit alignment in annotation conventions, and can be done simply through parameter sharing. We show that polyglot training can result in better labeling accuracy than a monolingual parser, especially for low-resource languages. We find that even a simple combination of data is as effective as more complex kinds of polyglot training. We include a breakdown into label categories of the differences between the monolingual and polyglot models. Our findings indicate that polyglot training consistently improves label accuracy for common labels.\nWe find that even a simple combination of data is as effective as more complex kinds of polyglot training.",

        "evidence": "For an ever increasing spectrum of applications (e.g., medical text analysis, opinion mining, sentiment analysis, social media text analysis, customer intelligence, fraud analytics etc.) mining and analysis of unstructured natural language text data is necessary BIBREF0, BIBREF1, BIBREF2.\nOne of key challenge while designing such text analytics (TA) applications is to identify right set of features. For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nOne of key challenge while designing such text analytics (TA) applications is to identify right set of features.",

        "answer": "Yes, they do.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nFinally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases.",

We now write in the paper: “Hopfield networks are energy-based, binary associative memories, which popularized artificial neural networks in the 1980s (Hopfield,1982; 1984). Associative memory networks have been designed to store and retrieve samples. Their storage capacity can be considerably increased by polynomial terms in the energy function (Chen et al., 1986; Psaltis & Cheol, 1986; Baldi & Venkatesh, 1987; Gardner, 1987; Abbott & Arian, 1987; Horn & Usher, 1988; Caputo & Niemann, 2002; Krotov & Hopfield, 2016). In contrast to these binary memory networks, we use continuous associative memory networks with very high storage capacity. These modern Hopfield networks for deep learning architectures have an energy function with continuous states and can retrieve samples with only one update (Ramsauer et al., 2021; 2020). Modern Hopfield Networks have already been successfully applied to immune repertoire classification (Widrich et al., 2020) and chemical reaction prediction (Seidl et al., 2021)”\nWe also added to the paper: “Modern Hopfield networks is a new concept for contrastive learning. In bioinformatics the covariance structure in a sequence is reinforced by first retrieving similar sequences from a database and then aligning them. Conserved regions are characterized by high local covariance in the alignment (Dickson & Gloor, 2012; Kreth & Fodor, 2014). Modern Hopfield networks detect high covariances of embedded features, which is conveyed by the retrieved sample that corresponds to an alignment.”\nFurthermore, we give a review of modern Hopfield networks in the Appendix A.4.",

One way is to use a process called electrolysis to extract oxygen from water.\n\nWater: Water is essential for survival, so you'll need to find a source of water on Mars. This could be in the form of ice or underground reserves.\n\nFood: Growing your own food on Mars would be difficult, but not impossible. You could use hydroponics or aeroponics to grow plants indoors, or find ways to grow crops outdoors.\n\nShelter: Mars' harsh environment would require a well-built shelter to protect you from the extreme cold, radiation, and dust storms. The shelter would need to be well insulated and sealed to prevent air leaks.\n\nEnergy: You'll need a reliable source of energy to power your shelter and equipment. Solar panels could be used to generate electricity, or nuclear reactors could be used for more efficient energy production.\n\nCommunications: Communication with Earth would be crucial for survival. You would need a reliable communication system to send and receive messages from Earth, as well as to coordinate with other astronauts on Mars.\n\nMedical Supplies: Medical emergencies could arise on Mars, so having a well-stocked medical kit and the knowledge to treat basic medical issues would be important.\n\nMental Health: Living in isolation on Mars could take a toll on your mental health. Maintaining social connections with other astronauts, regular exercise, and engaging in activities to combat boredom would be important for mental health.\n\nSurviving on Mars would require a great deal of preparation, resources, and expertise.

        "evidence": "As presented in this section, we conducted two series of experiments to analyze the property of IMTC. First, we qualitatively evaluated the diversity of options learned by IMTC with intrinsic rewards, without any extrinsic rewards. Second, we quantitatively test the reusability of learned options by). Also, we can see that the magnitude of intra-option policies tends larger with constant rewards. Right: Options learned by other methods. OC produces a dead option 3 that terminates everywhere and never-ending options 0 and 1. About intra-option policies, all methods successfully avoided learning the same policy, but they only have two directions.\ntask adaptation on a specific task. As a baseline of termination learning method, we compared our method with OC. OC is trained with VIC rewards during pre-training. We did not compare IMTC with TC because our TC implementation failed to learn options with relatively small termination regions as reported in the paper, and there is no official public code for TC 1 . During pre-training without extrinsic rewards, IMTC receives intrinsic rewards when the current option terminates. We compare three IMTC variants with different intrinsic rewards: (i) VIC, (ii) RVIC, and (iii) constant value (R IMTC = 0.01). Note that R IMTC = 0.01 is chosen from [0.1, 0.05, 0.01] based on the task adaptation results. We also compare IMTC with vanilla VIC and RVIC with fixed termination probabilities. We used ∀ x β o (x) = 0.1 since it performed the best in task adaptation experiments, while 0.05 was used in. Note that RVIC's objective I(X s ; O|x f ) is different from ours, while IMTC and VIC share almost the same objective. Thus, the use of VIC is more natural, and the combination with RVIC is tested to show the applicability of IMTC. Further details of our VIC and RVIC implementation are found in Appendix B. In order to check only the effect of the different methods for learning beta β o , the rest of the implementation is the same for all these methods. That is, OC, vanilla VIC, and vanilla RVIC are also based on PPO and advantage estimation methods in Section 4.2. In this section, we fix the number of options as |O| = 4 for all option-learning methods. We further investigated the effect of the number of options Appendix C, where we confirmed that |O| = 4 is sufficient for most domains. All environments that we used for experiments are implemented on the MuJoCo physics simulator. We further describe the details in Appendix C.\nOption Learning From Intrinsic Rewards We now qualitatively compare the options learned by IMTC with options of other methods. Learned options depend on the reward structure in the environment, which enables manually designing good reward functions for learning diverse options. Thus, we employed a reward-free RL setting where no reward is given to agents. Instead, each compared method uses some intrinsic rewards, as explained. We fix µ as µ(o|x) = 1 |O| in this experiment, since we assume that the future tasks are uniformly distributed. Intra-option policies are trained by PPO and independent GAE (8). We show network architectures and hyperparameters in Appendix C. We set the episode length to 1 × 10 4 , i.e., an agent is reset to its starting position after 1 × 10 4 steps. For all visualizations, we chose the best one from five independent runs with different random seeds.  We visualized learned options in PointReach environment shown in Figure. In this environment, an agent controls the ball initially placed at the center of the room. The state space consists of positions (x, y) and velocities (∆x, ∆y) of an agent, and the action space consists of acceralations ( ∆x ∆t , ∆y ∆t ). Figure shows the options learned in this environment after 4 × 10 6 steps. Each arrow represents the mean value of intra-option policies, and the heatmaps represent β o . In this experiment, we observed the effect of IMTC clearly, for both termination regions and intra-option policies. Interestingly, we don't see clear differences between options learned with VIC and RVIC rewards, while constant rewards tend to make options peaker. OC failed to learn meaningful termination regions: option 0 and 1 never terminate, and option 3 terminates almost everywhere. This result confirms that IMTC can certainly diversify options. Moreover, compared to vanilla VIC and RVIC, intra-option policies learned by IMTC with VIC or RVIC rewards are clearer, in terms of both the magnitude and directions of policies. We believe that this is because diversifying termination regions gives more biased samples to the option classifiers employed by VIC and RVIC. Figure Transferring skills via task adaptation Now we quantitatively test the reusability of learned options by task adaptation with specific reward functions. Specifically, we first trained agents with intrinsic rewards as per the previous section. Then we transferred agents to an environment with the same state and action space but with external rewards. We prepared multiple reward functions, which we call tasks, for each domain and evaluated the averaged performance over tasks. We compare IMTC with OC, vanilla VIC, vanilla RVIC, and PPO without pre-training. Also, we compare three variants of IMTC with different intrinsic rewards during pre-training. For a fair comparison, UGAE (9) and PPO are used for all options learning methods. Note that we found UGAE is very effective in this experiments, as we show the ablation study in Appendix C.6. For vanilla VIC and vanilla RVIC, termination probability is fixed to 0.1 through pre-training and task adaptation. -greedy based on Q O with = 0.1 is used as the option selection policy µ. We hypothesize that diverse options learned by IMTC can help quickly adapt to given tasks, supposing the diversity of tasks.\nFigure shows all domains used for task adaptation experiments. For simplicity, all tasks have goalbased sparse reward functions. I.e., an agent receives R t = 1.0 when it satisfies a goal condition, and otherwise the control cost −0.0001 is given. Red circles show possible goal locations for each task. When the agent fails to reach the goal after 1000 steps, it is reset to a starting position. PointReach, SwimmerReach, and AntReach are simple navigation tasks where an agent aim to just navigate itself to the goal. We also prepared tasks with object manipulation: in PointBilliard and AntBilliard an agent aims to kick the blue ball to the goal position, and in PointPush and AntPush, it has to push the block out of the way to the goal. We pre-traine options learning agents for 4 × 10 6 environmental steps and additionally trained them for 1 × 10 6 steps for each task. Figure shows learning curves and scatter plots drawn from five independent runs with  different random seeds per domain. 2 Here, we observed that IMTC with VIC or RVIC rewards performed the best or was compatible with baselines. IMTC with VIC performed better than OC with VIC except for AntRearch, which backs up the effectiveness of diversifying termination regions for learning reusable options. Also, IMTC with VIC and IMTC with RCIC respectively performed better in most of the tasks than VIC and RVIC with fixed termination probabilities. This result suggests that IMTC can boost the performance of option learning methods based on option classifiers, even when the objective is different as with RVIC. On the other hand, IMTC with constant rewards (R IMTC = 0.01) performed worse than IMTC with VIC or RVIC rewards, although it also learned diverse options as we show in Figure, suggesting the importance of adjusting rewards. We further analyzed the evolution of intrinsic rewards of VIC and RVIC in Appendix C.5. In addition, we can observe that IMTC's performance is especially better than other methods in relatively complex PointBilliard, AntBilliard, and AntPush, where object manipulation is required. Considering that manipulated balls and boxes move faster than agents in these domains, a choice of options can lead to larger differences in the future state. IMTC is suitable to these domains since it maximizes the diversity of the resulting states, while PPO struggles to learn. Contrary, IMTC's performance is close to other methods in Reach tasks, where the goal states are relatively close to the starting states in terms of euclidian distances.\nGridworld experiments and limitation of the method Although IMTC successfully learned diverse options in MuJoCo experiments, our analysis in Figure shows the possibility of learning options that are not interesting but have large MI. We further investigated this possibility by visualizing options in a classical four rooms gridworld in Appendix C.8. Interestingly, we observed that IMTC could fall into diverse but unmeaningful options in that environment. We believe that IMTC is often sufficient in a large environment where a randomly-initialized agent rarely gets the same trajectory. However, when the number of possible trajectories is small, diversifying the destinations could be insufficient. In such cases, it can be necessary to extend IMTC to diversify trajectories as done in.\nIn addition, we can observe that IMTC’s performance is especially better than other methods in relatively complex PointBilliard, AntBilliard, and AntPush, where object manipulation is required. Considering that manipulated balls and boxes move faster than agents in these domains, a choice of options can lead to larger differences in the future state. IMTC is suitable to these domains since it maximizes the diversity of the resulting states, while PPO struggles to learn.

Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger.\n\nDredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging systems can either be shore-based, brought to a location based on barges, or built into purpose built vessels.\n\nDredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release legacy human-sourced toxins captured in the sediment.

        "evidence": "Cancer is one of the leading causes of death in the world, with over 80,000 deaths registered in Canada in 2017 (Canadian Cancer Statistics 2017). A computer-aided system for cancer diagnosis usually involves a pathologist rendering a descriptive report after examining the tissue glass slides obtained from the biopsy of a patient. A pathology report contains specific analysis of cells and tissues, and other histopathological indicators that are crucial for diagnosing malignancies. An average sized laboratory may produces a large quantity of pathology reports annually (e.g., in excess of 50,000), but these reports are written in mostly unstructured text and with no direct link to the tissue sample. Furthermore, the report for each patient is a personalized document and offers very high variability in terminology due to lack of standards and may even include misspellings and missing punctuation, clinical diagnoses interspersed with complex explanations, different terminology to label the same malignancy, and information about multiple carcinoma appearances included in a single report BIBREF0 .\nIn Canada, each Provincial and Territorial Cancer Registry (PTCR) is responsible for collecting the data about cancer diseases and reporting them to Statistics Canada (StatCan). Every year, Canadian Cancer Registry (CCR) uses the information sources of StatCan to compile an annual report on cancer and tumor diseases. Many countries have their own cancer registry programs. These programs rely on the acquisition of diagnostic, treatment, and outcome information through manual processing and interpretation from various unstructured sources (e.g., pathology reports, autopsy/laboratory reports, medical billing summaries). The manual classification of cancer pathology reports is a challenging, time-consuming task and requires extensive training BIBREF0 .\nWith the continued growth in the number of cancer patients, and the increase in treatment complexity, cancer registries face a significant challenge in manually reviewing the large quantity of reports BIBREF1 , BIBREF0 . In this situation, Natural Language Processing (NLP) systems can offer a unique opportunity to automatically encode the unstructured reports into structured data. Since, the registries already have access to the large quantity of historically labeled and encoded reports, a supervised machine learning approach of feature extraction and classification is a compelling direction for making their workflow more effective and streamlined. If successful, such a solution would enable processing reports in much lesser time allowing trained personnel to focus on their research and analysis. However, developing an automated solution with high accuracy and consistency across wide variety of reports is a challenging problem.\nFor cancer registries, an important piece of information in a pathology report is the associated ICD-O code which describes the patient's histological diagnosis, as described by the World Health Organization's (WHO) International Classification of Diseases for Oncology BIBREF2 . Prediction of the primary diagnosis from a pathology report provides a valuable starting point for exploration of machine learning techniques for automated cancer surveillance. A major application for this purpose would be “auto-reporting” based on analysis of whole slide images, the digitization of the biopsy glass slides. Structured, summarized and categorized reports can be associated with the image content when searching in large archives. Such as system would be able to drastically increase the efficiency of diagnostic processes for the majority of cases where in spite of obvious primary diagnosis, still time and effort is required from the pathologists to write a descriptive report.\nThe primary objective of our study is to analyze the efficacy of existing machine learning approaches for the automated classification of pathology reports into different diagnosis categories. We demonstrate that TF-IDF feature vectors combined with linear SVM or XGBoost classifier can be an effective method for classification of the reports, achieving up to 83% accuracy. We also show that TF-IDF features are capable of identifying important keywords within a pathology report. Furthermore, we have created a new dataset consisting of 1,949 pathology reports across 37 primary diagnoses. Taken together, our exploratory experiments with a newly introduced dataset on pathology reports opens many new opportunities for researchers to develop a scalable and automatic information extraction from unstructured pathology reports.\nWe demonstrate that TF-IDF feature vectors combined with linear SVM or XGBoost classifier can be an effective method for classification of the reports, achieving up to 83% accuracy.

She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country artist to write a U.S. platinum-certified album.\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history.

For example, driving distance off the tee paired with greens in regulation play a crucial role in scoring, as opposed to putting whereas you have a 20 foot putt compared to a 40 foot putt, your make percentages are both low.\n\nLearning how to practice correctly can also improve your on course scoring as most approach practice incorrectly.  Zombie range sessions have become the norm, but rarely in golf do you have the same shot twice in a row.  Implement that same theory on the driving range so you have more of a feel of what on course play will feel like.\n\nFinally, in order to improve your scoring, you need to build a sharp mental game while you play.  This includes visualizing your shot before you hit it, being able to clear your head of all unwanted thoughts other than the shot you want to hit, and implementing a pre shot routine that is easily replicable.\n\nBy applying these core 4 strategies, you should see your golf scores decrease without any significant change in your actual swing.",

After being kidnapped to Anatolia he was brought to Egypt as a slave by Ibrahim Pasha in 1830 and was converted to Islam. Immediately following his arrival, he studied at al-Maktab al-Amiri and obtained his advanced degree in 1834. He was fluent in Greek and was elevated to the rank of First Lieutenant by Egypt's viceroy Muhammad Ali Pasha. In 1836, he became head of the Accounting and Revenue Agencies. He was promoted to the rank of bikbashi (Lieutenant Colonel) in 1840, then kaymakam (Colonel) in 1844, and finally amiralay (Brigadier General) in 1846.[citation needed]\n\nHe held the positions of Minister of Finance (1858–1860), then Minister of War (1860–1861).[citation needed] He became Inspector for the Maritime Provinces in 1862, and later Assistant (Arabic: باشمعاون) to viceroy Isma'il Pasha (1863–1865). He was granted the title of beylerbey and then appointed President of the Privy council in 1868. He was appointed President of the Chamber of Deputies (1866–1867), then Minister of Interior in 1867, then Minister of Agriculture and Trade in 1875.[citation needed] He again held the Finance portfolio in Muhammad Sharif Pasha's first government (1879). After the fall of Mahmoud Sami el-Baroudi's government, Isma'il Ragheb became Prime Minister of Egypt in 1882.[citation needed] Although his government was short-lived (it lasted from 17 June to 21 August only), it was the only one to present concrete programs. His achievements include the modernisation of the budget through the inventory of revenues and expenses, the Law on Salaries, and the La'eha Sa'ideyya as well as several agricultural laws.[citation needed]\n\nIsma'il Ragheb died in 1884.[citation needed]",

        "evidence": "The majority of the English text available worldwide is generated by non-native speakers BIBREF0 . Such texts introduce a variety of challenges, most notably grammatical errors, and are of paramount importance for the scientific study of language acquisition as well as for NLP. Despite the ubiquity of non-native English, there is currently no publicly available syntactic treebank for English as a Second Language (ESL).\nTo address this shortcoming, we present the Treebank of Learner English (TLE), a first of its kind resource for non-native English, containing 5,124 sentences manually annotated with POS tags and dependency trees. The TLE sentences are drawn from the FCE dataset BIBREF1 , and authored by English learners from 10 different native language backgrounds. The treebank uses the Universal Dependencies (UD) formalism BIBREF2 , BIBREF3 , which provides a unified annotation framework across different languages and is geared towards multilingual NLP BIBREF4 . This characteristic allows our treebank to support computational analysis of ESL using not only English based but also multilingual approaches which seek to relate ESL phenomena to native language syntax.\nWhile the annotation inventory and guidelines are defined by the English UD formalism, we build on previous work in learner language analysis BIBREF5 , BIBREF6 to formulate an additional set of annotation conventions aiming at a uniform treatment of ungrammatical learner language. Our annotation scheme uses a two-layer analysis, whereby a distinct syntactic annotation is provided for the original and the corrected version of each sentence. This approach is enabled by a pre-existing error annotation of the FCE BIBREF7 which is used to generate an error corrected variant of the dataset. Our inter-annotator agreement results provide evidence for the ability of the annotation scheme to support consistent annotation of ungrammatical structures.\nFinally, a corpus that is annotated with both grammatical errors and syntactic dependencies paves the way for empirical investigation of the relation between grammaticality and syntax. Understanding this relation is vital for improving tagging and parsing performance on learner language BIBREF8 , syntax based grammatical error correction BIBREF9 , BIBREF10 , and many other fundamental challenges in NLP. In this work, we take the first step in this direction by benchmarking tagging and parsing accuracy on our dataset under different training regimes, and obtaining several estimates for the impact of grammatical errors on these tasks.\nTo summarize, this paper presents three contributions. First, we introduce the first large scale syntactic treebank for ESL, manually annotated with POS tags and universal dependencies. Second, we describe a linguistically motivated annotation scheme for ungrammatical learner English and provide empirical support for its consistency via inter-annotator agreement analysis. Third, we benchmark a state of the art parser on our dataset and estimate the influence of grammatical errors on the accuracy of automatic POS tagging and dependency parsing.\nThe remainder of this paper is structured as follows. We start by presenting an overview of the treebank in section SECREF2 . In sections SECREF3 and SECREF4 we provide background information on the annotation project, and review the main annotation stages leading to the current form of the dataset. The ESL annotation guidelines are summarized in section SECREF5 . Inter-annotator agreement analysis is presented in section SECREF6 , followed by parsing experiments in section SECREF7 . Finally, we review related work in section SECREF8 and present the conclusion in section SECREF9 .\nSecond, we describe a linguistically motivated annotation scheme for ungrammatical learner English and provide empirical support for its consistency via inter-annotator agreement analysis.",

        "evidence": "In recent years, the micro-blogging platform Twitter has become a major social media platform with hundreds of millions of users. People turn to Twitter for a variety of purposes, from everyday chatter to reading about breaking news. The volume plus the public nature of Twitter (less than 10% of Twitter accounts are private BIBREF0 ) have made Twitter a great source of data for social and behavioural studies. These studies often require an understanding of what people are tweeting about. Though this can be coded manually, in order to take advantage of the volume of tweets available automatic analytic methods have to be used. There has been extensive work done on computational methods for analysing the linguistic content of tweets. However, there has been very little work done on classifying the pragmatics of tweets. Pragmatics looks beyond the literal meaning of an utterance and considers how context and intention contribute to meaning. A major element of pragmatics is the intended communicative act of an utterance, or what the utterance was meant to achieve. It is essential to study pragmatics in any linguistic system because at the core of linguistic analysis is studying what language is used for or what we do with language. Linguistic communication and meaning can not truly be studied without studying pragmatics. Proposed by Austin BIBREF1 and refined by Searle BIBREF2 , speech act theory can be used to study pragmatics. Amongst other things, the theory provides a formalized taxonomy BIBREF3 of a set of communicative acts, more commonly known as speech acts.\nThere has been extensive research done on speech act (also known as dialogue act) classification in computational linguistics, e.g., BIBREF4 . Unfortunately, these methods do not map well to Twitter, given the noisy and unconventional nature of the language used on the platform. In this work, we created a supervised speech act classifier for Twitter, using a manually annotated dataset of a few thousand tweets, in order to be better understand the meaning and intention behind tweets and uncover the rich interactions between the users of Twitter. Knowing the speech acts behind a tweet can help improve analysis of tweets and give us a better understanding of the state of mind of the users. Moreover, ws we have shown in our previous works BIBREF5 , BIBREF6 , speech act classification is essential for detection of rumors on Twitter. Finally, knowing the distribution of speech acts of tweets about a particular topic can reveal a lot about the general attitude of users about that topic (e.g., are they confused and are asking a lot of questions? Are they outraged and demanding action? Etc).\nIn this work, we created a supervised speech act classifier for Twitter, using a manually annotated dataset of a few thousand tweets, in order to be better understand the meaning and intention behind tweets and uncover the rich interactions between the users of Twitter",

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nExperimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods.",

        "question": "Who built Sigiriya fortress in Sri Lanka?",
        "evidence": "It is likely that the area around Sigiriya may have been inhabited since prehistoric times. There is clear evidence that the many rock shelters and caves in the vicinity were occupied by Buddhist monks and ascetics from as early as the 3rd century BC. The earliest evidence of human habitation at Sigiriya is the Aligala rock shelter to the east of Sigiriya rock, indicating that the area was occupied nearly five thousand years ago during the Mesolithic Period.\n\nBuddhist monastic settlements were established during the 3rd century BC in the western and northern slopes of the boulder-strewn hills surrounding the Sigiriya rock. Several rock shelters or caves were created during this period. These shelters were made under large boulders, with carved drip ledges around the cave mouths. Rock inscriptions are carved near the drip ledges on many of the shelters, recording the donation of the shelters to the Buddhist monastic order as residences. These were made in the period between the 3rd century BCE and the 1st century AD.\n\nIn 477 AD, Kashyapa I, the king’s son by a non-royal consort, seized the throne from King Dhatusena, following a coup assisted by Migara, the King’s nephew and army commander. The rightful heir, Moggallana, fearing for his life, fled to South India. Afraid of an attack by Moggallana, Kashyapa moved the capital and his residence from the traditional capital of Anuradhapura to the more secure Sigiriya. During King Kashyapa’s reign (477 to 495 AD), Sigiriya was developed into a complex city and fortress. Most of the elaborate constructions on the rock summit and around it, including defensive structures, palaces, and gardens, date from this period.",

        "question": "Why the dataset was uniformly split into the training, validation, and test sets?",
        "answer": "This split is for the purpose of using historical data in the training set to predict new data in the test set.",
        "evidence": "Datasets: We use two recent benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . These two datasets are created to avoid reversible relation problems, thus the prediction task becomes more realistic and hence more challenging BIBREF18 . Table TABREF7 presents the statistics of WN18RR and FB15k-237.\nEvaluation protocol: Following BIBREF3 , for each valid test triple INLINEFORM0 , we replace either INLINEFORM1 or INLINEFORM2 by each of all other entities to create a set of corrupted triples. We use the “Filtered” setting protocol BIBREF3 , i.e., not taking any corrupted triples that appear in the KG into accounts. We rank the valid test triple and corrupted triples in descending order of their scores. We employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions). Lower MR, higher MRR or higher Hits@10 indicate better performance. Final scores on the test set are reported for the model obtaining the highest Hits@10 on the validation set.\nTraining protocol: We use the common Bernoulli strategy BIBREF20 , BIBREF21 when sampling invalid triples. For WN18RR, BIBREF22 found a strong evidence to support the necessity of a WordNet-related semantic setup, in which they averaged pre-trained word embeddings for word surface forms within the WordNet to create synset embeddings, and then used these synset embeddings to initialize entity embeddings for training their TransE association model. We follow this evidence in using the pre-trained 100-dimensional Glove word embeddings BIBREF23 to train a TransE model on WN18RR.\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 . For ConvKB, we use a new process of training up to 100 epochs and monitor the Hits@10 score after every 10 training epochs to choose optimal hyper-parameters with the Adam initial learning rate in INLINEFORM0 and the number of filters INLINEFORM1 in INLINEFORM2 . We obtain the highest Hits@10 scores on the validation set when using N= 400 and the initial learning rate INLINEFORM3 on WN18RR; and N= 100 and the initial learning rate INLINEFORM4 on FB15k-237.\nLike in ConvKB, we use the same pre-trained entity and relation embeddings produced by TransE to initialize entity and relation embeddings in our CapsE for both WN18RR and FB15k-237 ( INLINEFORM0 ). We set the batch size to 128, the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM1 ), and the number of iterations in the routing algorithm INLINEFORM2 in INLINEFORM3 . We run CapsE up to 50 epochs and monitor the Hits@10 score after each 10 training epochs to choose optimal hyper-parameters. The highest Hits@10 scores for our CapsE on the validation set are obtained when using INLINEFORM4 , INLINEFORM5 and the initial learning rate at INLINEFORM6 on WN18RR; and INLINEFORM7 , INLINEFORM8 and the initial learning rate at INLINEFORM9 on FB15k-237.\nDataset: We use the SEARCH17 dataset BIBREF12 of query logs of 106 users collected by a large-scale web search engine. A log entity consists of a user identifier, a query, top-10 ranked documents returned by the search engine and clicked documents along with the user's dwell time. BIBREF12 constructed short-term (session-based) user profiles and used the profiles to personalize the returned results. They then employed the SAT criteria BIBREF26 to identify whether a returned document is relevant from the query logs as either a clicked document with a dwell time of at least 30 seconds or the last clicked document in a search session (i.e., a SAT click). After that, they assigned a INLINEFORM0 label to a returned document if it is a SAT click and also assigned INLINEFORM1 labels to the remaining top-10 documents. The rank position of the INLINEFORM2 labeled documents is used as the ground truth to evaluate the search performance before and after re-ranking.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set BIBREF12 . The training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.\nEvaluation protocol: Our CapsE is used to re-rank the original list of documents returned by a search engine as follows: (i) We train our model and employ the trained model to calculate the score for each INLINEFORM0 triple. (ii) We then sort the scores in the descending order to obtain a new ranked list. To evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1. For each metric, the higher value indicates better ranking performance.\nWe compare CapsE with the following baselines using the same experimental setup: (1) SE: The original rank is returned by the search engine. (2) CI BIBREF27 : This baseline uses a personalized navigation method based on previously clicking returned documents. (3) SP BIBREF9 , BIBREF11 : A search personalization method makes use of the session-based user profiles. (4) Following BIBREF12 , we use TransE as a strong baseline model for the search personalization task. Previous work shows that the well-known embedding model TransE, despite its simplicity, obtains very competitive results for the knowledge graph completion BIBREF28 , BIBREF29 , BIBREF14 , BIBREF30 , BIBREF15 . (5) The CNN-based model ConvKB is the most closely related model to our CapsE.\nEmbedding initialization: We follow BIBREF12 to initialize user profile, query and document embeddings for the baselines TransE and ConvKB, and our CapsE.\nWe train a LDA topic model BIBREF31 with 200 topics only on the relevant documents (i.e., SAT clicks) extracted from the query logs. We then use the trained LDA model to infer the probability distribution over topics for every returned document. We use the topic proportion vector of each document as its document embedding (i.e. INLINEFORM0 ). In particular, the INLINEFORM1 element ( INLINEFORM2 ) of the vector embedding for document INLINEFORM3 is: INLINEFORM4 where INLINEFORM5 is the probability of the topic INLINEFORM6 given the document INLINEFORM7 .\nWe also represent each query by a probability distribution vector over topics. Let INLINEFORM0 be the set of top INLINEFORM1 ranked documents returned for a query INLINEFORM2 (here, INLINEFORM3 ). The INLINEFORM4 element of the vector embedding for query INLINEFORM5 is defined as in BIBREF12 : INLINEFORM6 , where INLINEFORM7 is the exponential decay function of INLINEFORM8 which is the rank of INLINEFORM9 in INLINEFORM10 . And INLINEFORM11 is the decay hyper-parameter ( INLINEFORM12 ). Following BIBREF12 , we use INLINEFORM13 . Note that if we learn query and document embeddings during training, the models will overfit to the data and will not work for new queries and documents. Thus, after the initialization process, we fix (i.e., not updating) query and document embeddings during training for TransE, ConvKB and CapsE.\nIn addition, as mentioned by BIBREF9 , the more recently clicked document expresses more about the user current search interest. Hence, we make use of the user clicked documents in the training set with the temporal weighting scheme proposed by BIBREF11 to initialize user profile embeddings for the three embedding models.\nHyper-parameter tuning: For our CapsE model, we set batch size to 128, and also the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM0 ). The number of iterations in the routing algorithm is set to 1 ( INLINEFORM1 ). For the training model, we use the Adam optimizer with the initial learning rate INLINEFORM2 INLINEFORM3 INLINEFORM4 INLINEFORM5 INLINEFORM6 INLINEFORM7 . We also use ReLU as the activation function INLINEFORM8 . We select the number of filters INLINEFORM9 . We run the model up to 200 epochs and perform a grid search to choose optimal hyper-parameters on the validation set. We monitor the MRR score after each training epoch and obtain the highest MRR score on the validation set when using INLINEFORM10 and the initial learning rate at INLINEFORM11 .\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 and then follow their training protocols to tune hyper-parameters for TransE and ConvKB, respectively. We also monitor the MRR score after each training epoch and attain the highest MRR score on the validation set when using margin = 5, INLINEFORM0 -norm and SGD learning rate at INLINEFORM1 for TransE; and INLINEFORM2 and the Adam initial learning rate at INLINEFORM3 for ConvKB.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set (Vu et al., 2017).",

These lexicons associate words to corresponding sentiment or emotion metrics. On the other hand, the semantic meaning of words, sentences, and documents are preserved and compactly represented using low dimensional vectors BIBREF1 instead of one hot encoding vectors which are sparse and high dimensional. Finally, there are traditional NLP features like word N-grams, character N-grams, Part-Of-Speech N-grams and word clusters which are known to perform well on various tasks.\nBased on these observations, the feature extraction step is implemented as a union of different independent feature extractors (featurizers) in a light-weight and easy to use Python program EmoInt . It comprises of all features available in the baseline model BIBREF2 along with additional feature extractors and bi-gram support.

Bing Liu BIBREF4 opinion lexicon extract opinion on customer reviews. +/-EffectWordNet BIBREF5 by MPQA group are sense level lexicons.

NRC Hashtag Sentiment Lexicon and Sentiment140 Lexicon BIBREF10 contains sentiment word associations computed on twitter corpus via Hashtags and Emoticons. SentiWordNet BIBREF11 assigns to each synset of WordNet three sentiment scores: positivity, negativity, objectivity. Negation lexicons collections are used to count the total occurrence of negative words. In addition to these, SentiStrength BIBREF12 application which estimates the strength of positive and negative sentiment from tweets is also added.\nWord Vectors: We focus primarily on the word vector representations (word embeddings) created specifically using the twitter dataset. GloVe BIBREF13 is an unsupervised learning algorithm for obtaining vector representations for words. 200-dimensional GloVe embeddings trained on 2 Billion tweets are integrated. Edinburgh embeddings BIBREF14 are obtained by training skip-gram model on Edinburgh corpus BIBREF15 . Since tweets are abundant with emojis, Emoji embeddings BIBREF16 which are learned from the emoji descriptions have been used. Embeddings for each tweet are obtained by summing up individual word vectors and then dividing by the number of tokens in the tweet.\nSyntactic Features: Syntax specific features such as Word N-grams, Part-Of-Speech N-grams BIBREF17 , Brown Cluster N-grams BIBREF18 obtained using TweetNLP project have been integrated into the system.\nThe final feature vector is the concatenation of all the individual features. For example, we concatenate average word vectors, sum of NRC Affect Intensities, number of positive and negative Bing Liu lexicons, number of negation words and so on to get final feature vector. The scaling of final features is not required when used with gradient boosted trees. However, scaling steps like standard scaling (zero mean and unit normal) may be beneficial for neural networks as the optimizers work well when the data is centered around origin.\nA total of fourteen different feature extractors have been implemented, all of which can be enabled or disabled individually to extract features from a given tweet.\nFourteen such feature extractors have been implemented which can be clubbed into 3 major categories: • Lexicon Features • Word Vectors • Syntax Features",

Even though low-resource settings have also been explored, this progress has overwhelmingly been observed in languages with significant data resources that can be leveraged to train deep neural networks. Low-resource languages still lag behind.\nEndangered languages pose an additional challenge. The process of documenting an endangered language typically includes the creation of word lists, audio and video recordings, notes, or grammar fragments, with the created resources then stored in large online linguistics archives. This process is often hindered by the Transcription Bottleneck: the linguistic fieldworker and the language community may not have time to transcribe all of the recordings and may only transcribe segments that are linguistically salient for publication or culturally significant for the creation of community resources.\nWith this work we make publicly available a large corpus in Mapudungun, a language of the indigenous Mapuche people of southern Chile and western Argentina. We hope to ameliorate the resource gap and the transcription bottleneck in two ways. First, we are providing a larger data set than has previously been available, and second, we are providing baselines for NLP tasks (speech recognition, speech synthesis, and machine translation). In providing baselines and datasets splits, we hope to further facilitate research on low-resource NLP for this language through our data set.

        "evidence": "Reading Comprehension (RC) has become a central task in natural language processing, with great practical value in various industries. In recent years, many large-scale RC datasets in English BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6 have nourished the development of numerous powerful and diverse RC models BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11. The state-of-the-art model BIBREF12 on SQuAD, one of the most widely used RC benchmarks, even surpasses human-level performance. Nonetheless, RC on languages other than English has been limited due to the absence of sufficient training data. Although some efforts have been made to create RC datasets for Chinese BIBREF13, BIBREF14 and Korean BIBREF15, it is not feasible to collect RC datasets for every language since annotation efforts to collect a new RC dataset are often far from trivial. Therefore, the setup of transfer learning, especially zero-shot learning, is of extraordinary importance.\nExisting methods BIBREF16 of cross-lingual transfer learning on RC datasets often count on machine translation (MT) to translate data from source language into target language, or vice versa. These methods may not require a well-annotated RC dataset for the target language, whereas a high-quality MT model is needed as a trade-off, which might not be available when it comes to low-resource languages.\nIn this paper, we leverage pre-trained multilingual language representation, for example, BERT learned from multilingual un-annotated sentences (multi-BERT), in cross-lingual zero-shot RC. We fine-tune multi-BERT on the training set in source language, then test the model in target language, with a number of combinations of source-target language pair to explore the cross-lingual ability of multi-BERT. Surprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese. Recent studies BIBREF17, BIBREF12, BIBREF18 show that cross-lingual language models have the ability to enable preliminary zero-shot transfer on simple natural language understanding tasks, but zero-shot transfer of RC has not been studied. To our knowledge, this is the first work systematically exploring the cross-lingual transferring ability of multi-BERT on RC tasks.\nIn this paper, we leverage pre-trained multilingual language representation, for example, BERT learned from multilingual un-annotated sentences (multi-BERT), in cross-lingual zero-shot RC.

The corpus comprises 8,275 sentences and 167,739 words in total. However, as mentioned above, only case presentation sections, headings and abstracts are annotated. The numbers of annotated entities are summarized in Table TABREF24.\nFindings are the most frequently annotated type of entity. This makes sense given that findings paint a clinical picture of the patient's condition. The number of tokens per entity ranges from one token for all types to 5 tokens for cases (average length 3.1), nine tokens for conditions (average length 2.0), 16 tokens for factors (average length 2.5), 25 tokens for findings (average length 2.6) and 18 tokens for modifiers (average length 1.4) (cf. Table TABREF24). Examples of rather long entities are given in Table TABREF25.\nEntities can appear in a discontinuous way. We model this as a relation between two spans which we call “discontinuous” (cf. Figure FIGREF26). Especially findings often appear as discontinuous entities, we found 543 discontinuous finding relations. The numbers for conditions and factors are lower with seven and two, respectively. Entities can also be nested within one another. This happens either when the span of one annotation is completely embedded in the span of another annotation (fully-nested; cf. Figure FIGREF12), or when there is a partial overlapping between the spans of two different entities (partially-nested; cf. Figure FIGREF12). There is a high number of inter-sentential relations in the corpus (cf. Table TABREF27). This can be explained by the fact that the case entity occurs early in each document; furthermore, it is related to finding and factor annotations that are distributed across different sentences.\nThe most frequently annotated relation in our corpus is the has-relation between a case entity and the findings related to that case. This correlates with the high number of finding entities.

        "evidence": "Lexical analysis, syntactic analysis, semantic analysis, disclosure analysis and pragmatic analysis are five main steps in natural language processing BIBREF0 , BIBREF1 . While morphology is a basic task in lexical analysis of English, word segmentation is considered a basic task in lexical analysis of Vietnamese and other East Asian languages processing. This task is to determine borders between words in a sentence. In other words, it is segmenting a list of tokens into a list of words such that words are meaningful.\nWord segmentation is the primary step in prior to other natural language processing tasks i. e., term extraction and linguistic analysis (as shown in Figure 1). It identifies the basic meaningful units in input texts which will be processed in the next steps of several applications. For named entity recognization BIBREF2 , word segmentation chunks sentences in input documents into sequences of words before they are further classified in to named entity classes. For Vietnamese language, words and candidate terms can be extracted from Vietnamese copora (such as books, novels, news, and so on) by using a word segmentation tool. Conformed features and context of these words and terms are used to identify named entity tags, topic of documents, or function words. For linguistic analysis, several linguistic features from dictionaries can be used either to annotating POS tags or to identifying the answer sentences. Moreover, language models can be trained by using machine learning approaches and be used in tagging systems, like the named entity recognization system of Tran et al. BIBREF2 .\nMany studies forcus on word segmentation for Asian languages, such as: Chinese, Japanese, Burmese (Myanmar) and Thai BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . Approaches for word segmentation task are variety, from lexicon-based to machine learning-based methods. Recently, machine learning-based methods are used widely to solve this issue, such as: Support Vector Machine or Conditional Random Fields BIBREF7 , BIBREF8 . In general, Chinese is a language which has the most studies on the word segmentation issue. However, there is a lack of survey of word segmentation studies on Asian languages and Vietnamese as well. This paper aims reviewing state-of-the-art word segmentation approaches and systems applying for Vietnamese. This study will be a foundation for studies on Vietnamese word segmentation and other following Vietnamese tasks as well, such as part-of-speech tagger, chunker, or parser systems.\nThere are several studies about the Vietnamese word segmentation task over the last decade. Dinh et al. started this task with Weighted Finite State Transducer (WFST) approach and Neural Network approach BIBREF9 . In addition, machine learning approaches are studied and widely applied to natural language processing and word segmentation as well. In fact, several studies used support vector machines (SVM) and conditional random fields (CRF) for the word segmentation task BIBREF7 , BIBREF8 . Based on annotated corpora and token-based features, studies used machine learning approaches to build word segmentation systems with accuracy about 94%-97%.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation. A all sided review of word segmentation will help next studies on Vietnamese natural language processing tasks have an up-to-date guideline and choose the most suitable solution for the task. The remaining part of the paper is organized as follows. Section II discusses building corpus in Vietnamese, containing linguistic issues and the building progress. Section III briefly mentions methods to model sentences and text in machine learning systems. Next, learning models and approaches for labeling and segmenting sequence data will be presented in Section IV. Section V mainly addresses two existing toolkits, vnTokenizer and JVnSegmenter, for Vietnamese word segmentation. Several experiments based on mentioned approaches and toolkits are described in Section VI. Finally, conclusions and future works are given in Section VII.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation.",

        "evidence": "We compare performances of our model with the implementation of BIBREF13 and the results are shown in Table TABREF43 . Our model obtains better performances in Multi-Domain scenario with an average improvement of 4.5%, where datasets are product reviews on different domains with similar sequence lengths and the same class number, thus producing stronger correlations. Multi-Cardinality scenario also achieves significant improvements of 2.77% on average, where datasets are movie reviews with different cardinalities.\nHowever, Multi-Objective scenario benefits less from multi-task learning due to lacks of salient correlation among sentiment, topic and question type. The QC dataset aims to classify each question into six categories and its performance even gets worse, which may be caused by potential noises introduced by other tasks. In practice, the structure of our model is flexible, as couplings and fusions between some empirically unrelated tasks can be removed to alleviate computation costs.\nWe further explore the influence of INLINEFORM0 in TOS on our model, which can be any positive integer. A higher value means larger and more various samples combinations, while requires higher computation costs.\nFigure FIGREF45 shows the performances of datasets in Multi-Domain scenario with different INLINEFORM0 . Compared to INLINEFORM1 , our model can achieve considerable improvements when INLINEFORM2 as more samples combinations are available. However, there are no more salient gains as INLINEFORM3 gets larger and potential noises from other tasks may lead to performance degradations. For a trade-off between efficiency and effectiveness, we determine INLINEFORM4 as the optimal value for our experiments.\nIn order to measure the correlation strength between two task INLINEFORM0 and INLINEFORM1 , we learn them jointly with our model and define Pair-wise Performance Gain as INLINEFORM2 , where INLINEFORM3 are the performances of tasks INLINEFORM4 and INLINEFORM5 when learned individually and jointly.\nWe calculate PPGs for every two tasks in Table TABREF35 and illustrate the results in Figure FIGREF47 , where darkness of colors indicate strength of correlation. It is intuitive that datasets of Multi-Domain scenario obtain relatively higher PPGs with each other as they share similar cardinalities and abundant low-level linguistic characteristics. Sentences of QC dataset are much shorter and convey unique characteristics from other tasks, thus resulting in quite lower PPGs.\nOur model obtains better performances in MultiDomain scenario with an average improvement of 4.5%, where datasets are product reviews on different domains with similar sequence lengths and the same class number, thus producing stronger correlations.",

        "evidence": "Recently, continuous space representations of words and phrases have been incorporated into SMT systems via neural networks. Specifically, addition of monolingual neural network language models BIBREF13 , BIBREF14 , neural network joint models (NNJM) BIBREF4 , and neural network global lexicon models (NNGLM) BIBREF3 have been shown to be useful for SMT. Neural networks have been previously used for GEC as a language model feature in the classification approach BIBREF15 and as a classifier for article error correction BIBREF16 . Recently, a neural machine translation approach has been proposed for GEC BIBREF17 . This method uses a recurrent neural network to perform sequence-to-sequence mapping from erroneous to well-formed sentences. Additionally, it relies on a post-processing step based on statistical word-based translation models to replace out-of-vocabulary words. In this paper, we investigate the effectiveness of two neural network models, NNGLM and NNJM, in SMT-based GEC. To the best of our knowledge, there is no prior work that uses these two neural network models for SMT-based GEC.\nGrammatical error correction (GEC) is a challenging task due to the variability of the type of errors and the syntactic and semantic dependencies of the errors on the surrounding context. Most of the grammatical error correction systems use classification and rule-based approaches for correcting specific error types. However, these systems use several linguistic cues as features. The standard linguistic analysis tools like part-of-speech (POS) taggers and parsers are often trained on well-formed text and perform poorly on ungrammatical text. This introduces further errors and limits the performance of rule-based and classification approaches to GEC. As a consequence, the phrase-based statistical machine translation (SMT) approach to GEC has gained popularity because of its ability to learn text transformations from erroneous text to correct text from error-corrected parallel corpora without any additional linguistic information. They are also not limited to specific error types. Currently, many state-of-the-art GEC systems are based on SMT or use SMT components for error correction BIBREF0 , BIBREF1 , BIBREF2 . In this paper, grammatical error correction includes correcting errors of all types, including word choice errors and collocation errors which constitute a large class of learners' errors.\nWe conduct experiments by incorporating NNGLM and NNJM both independently and jointly into our baseline system. The results of our experiments are described in Section SECREF23 . The evaluation is performed similar to the CoNLL 2014 shared task setting using the the official test data of the CoNLL 2014 shared task with annotations from two annotators (without considering alternative annotations suggested by the participating teams). The test dataset consists of 1,312 error-annotated sentences with 30,144 tokens on the source side. We make use of the official scorer for the shared task, M INLINEFORM0 Scorer v3.2 BIBREF19 , for evaluation. We perform statistical significance test using one-tailed sign test with bootstrap resampling on 100 samples.\nOn top of our baseline system described above, we incorporate the two neural network components, neural network global lexicon model (NNGLM) and neural network joint model (NNJM) as features.

Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes. Using Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers. This task raises several challenges. First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map.",

According to its literal meaning in Sanskrit, a Songkran occurs every month. However, the period that Thai people refer to as Songkran happens when the sun moves from Pisces to Aries in the zodiac. The correct name for this period should actually be Maha Songkran ('great Songkran) because it coincides with the arrival of a New Year. The Songkran festival is, therefore, a celebration of the New Year in accordance with the solar calendar. The celebration covers a period of three days: 13 April is regarded as Maha Songkran, the day that the sun moves into Aries on the zodiac or the last day of the old year. The next day, 14 April is called Wan Nao, the transitional day between the old and the new years, and 15 April is called Wan Thaloeng Sok (Thai: วันเถลิงศก 'to begin a new era or year'), New Year's day itself.",

However, given that most neural methods have many more complexity hyperparameters than the single hyperparameter that we were able to carefully control for linear models, obtaining accurate tuning and reliable performance evaluation is likely to be a challenge. Gradient-based hyper-parameter estimation methods, as initially attempted in; , together with efficient methods for long-inner loop hypergradient calculation, may benefit the former problem by making search in larger numbers of hyperparameters more feasible. Alternatively, using general purpose pre-trained features as we did here, and focusing on learning shallow models that can be accurately tuned for DG may be another promising avenue in practice. Although achieving state of the art performance is not our focus, we note that our results in Table are quite competitive with end-to-end trained state of the art, despite using fixed features and shallow models.\nOur analysis suggests that several existing methods that tried to tune learnable DG hyper-parameters by performance on a held-out domain (Balaji et al., 2018; Li et al., 2019) were broadly on the right track, and concurs with Gulrajani & Lopez-Paz (2021) that those methods with underspecified hyperparameter and model selection procedures are unhelpful",

He plays mainly as a central midfielder, but can also play as an attacking midfielder or as a defensive midfielder. He is widely regarded as one of the greatest midfielders of all time, and as the greatest ever Croatian footballer.\n\nBorn in Zadar, Modrić's childhood coincided with the Croatian War of Independence which displaced his family. In 2002, he was signed by Dinamo Zagreb at age 16, after showing promise with his hometown club NK Zadar's youth team. He continued his development in Zagreb, before spells on loan to Zrinjski Mostar and Inter Zaprešić. He made his debut for Dinamo in 2005 and won three consecutive league titles and domestic cups, being named the Prva HNL Player of the Year in 2007. In 2008, he moved to Premier League club Tottenham Hotspur for a club-record transfer fee of £16.5 million, where he led Spurs to their first UEFA Champions League appearance in almost 50 years, reaching the quarter-finals of the 2010–11 tournament.\n\nIn the summer of 2012, Modrić joined Real Madrid for a £30 million transfer fee. There he became a key contributor and helped the team win La Décima and was selected for the 2013–14 Champions League squad of the season. After Zinedine Zidane took over Madrid, Modrić was critical to three consecutive Champions League titles from 2015–16 to 2017–18, each time being voted into the squad of the season. He has won twenty-two major trophies at Real Madrid, including five UEFA Champions League titles, three La Liga titles, one Copa del Rey, four Supercopa de España titles, four UEFA Super Cup titles and five FIFA Club World Cup titles. He won the La Liga Award for \"Best Midfielder\" in 2016 for the second time, and the UEFA Club Football Award for \"Best Midfielder\" in 2017 and 2018. In 2015, he became the first Croatian player to be included in the FIFA FIFPRO World 11, in which he was regularly included until 2019 and then again in 2022, as well in the UEFA Team of the Year between 2016 and 2018. In 2018, Modrić became the first Croatian player to win the UEFA Men's Player of the Year Award, and by winning The Best FIFA Men's Player and Ballon d'Or awards, he became the first player other than Lionel Messi or Cristiano Ronaldo to claim the awards in more than a decade. In 2019, he was awarded the Golden Foot award for career results and personality.\n\nModrić made his international debut for Croatia against Argentina in March 2006, and scored his first international goal in a friendly match against Italy. Modrić has anchored Croatia's \"second Golden Generation\", participating in every major tournament Croatia has qualified for, including the UEFA Euro 2008, 2012, 2016, and 2020, as well as the 2006, 2014, 2018, and 2022 FIFA World Cup. At the Euro 2008, he was selected for the Team of the Tournament, becoming only the second Croatian to ever achieve this honour. Following group stage eliminations in his first two World Cups, Modrić led Croatia to the 2018 World Cup Final, winning the Golden Ball in process. At the following tournament, he led the team to a third-place finish, winning the Bronze Ball in process. In March 2021, he went on to become the country's most capped player in history.

        "question": "What is their English QG dataset?",
        "answer": "SQuAD 1.1.",
        "evidence": "We evaluate our model on the zero-shot cross-lingual answer-aware question generation task. The goal of question generation (QG) is to generate a question that asks towards the answer with the given passage and the expected answer. In the following experiments, we extend the QG task to the cross-lingual setting. By only using English QG training data, our goal is to generate questions in English or Chinese with the given passage-answer pair in English or Chinese.\nWe use SQuAD 1.1 BIBREF30 as the English QG dataset. It is a popular English question answering dataset containing over 100,000 questions and their corresponding annotated passages. Following BIBREF31, we regard the original development set as the test set, and sample 5000 examples from the training data of two datasets as the development sets. For Chinese QG, we follow the default data splits of WebQA BIBREF32. We regard the provided annotated evidence sentences as the input passages instead of entire documents. To construct the input sequence, we view the whole input passage as a single sentence, and concatenate the passage and the answer into one sequence with a special token S between them. During decoding Chinese, we utilize a subset of vocabulary, which is obtained from the passage sentences of the WebQA dataset.\nWe first conduct experiments on the supervised English-English QG setting. We compare our model to the following baselines:\nCorefNqg BIBREF33 A sequence-to-sequence model with attention mechanism and a feature-rich encoder.\nMp-Gsn BIBREF31 A sequence-to-sequence model with gated self-attention and maxout pointer mechanism.\nXlm BIBREF5 The current state-of-the-art cross-lingual pre-training model. We initialize the Transformer-based sequence-to-sequence model with pre-trained XLM.\nWe evaluate models with BLEU-4 (BL-4), ROUGE (RG) and METEOR (MTR) metrics. As shown in Table TABREF16, our model outperforms the baselines, which demonstrates that our pre-trained model provides a good initialization for NLG.\nWe conduct experiments on the zero-shot Chinese-Chinese QG task to evaluate the cross-lingual transfer ability. In this task, models are trained with English QG data but evaluated with Chinese QG examples. We include the following models as our baselines:\nXlm Fine-tuning XLM with the English QG data.\nPipeline (Xlm) The pipeline of translating input Chinese sentences into English first, then performing En-En-QG with the XLM model, and finally translating back to the Chinese. We use the Transformer as the translator, which is also trained on the MultiUN dataset.\nPipeline (Xlm) with Google Translator Same to Pipeline (Xlm) but using Google Translator to translate the texts.\nWe evaluate models by both automatic evaluation metrics and human experts. The automatic metrics scores are computed by regarding each Chinese character as a token. For human evaluation, we consider three metrics for the generated questions: relatedness, fluency, and correctness, which are represented as integers ranged from 1 to 3. We randomly select 100 passage-answer pairs from the English QG test set, and use the models to generate questions. Then we present these examples to three experts to ask for the above scores. In Table TABREF17 and Table TABREF18, we present the results for the zero-shot Zh-Zh-QG. The results of monolingual supervised models are also reported in Table TABREF16 as reference. In the automatic evaluation, our model consistently performs better than baselines in both zero-shot and monolingual supervised setting. In the human evaluation, our model also obtains significant improvements in terms of relatedness and correctness.\nIn the zero-shot English-Chinese question generation experiments, we use Xlm and Pipeline (Xlm) as our baselines. Pipeline (Xlm) is a pipeline method that uses En-En-QG with Xlm to generate questions, and then translates the results to Chinese. Because there is no annotations for En-Zh-QG, we perform human evaluation studies for this setting. Table TABREF19 shows the human evaluation results, where our model surpasses all the baselines especially in terms of relatedness and correctness.\nWe also conduct experiments for zero-shot Chinese-English question generation, and adopt the same evaluation procedure to En-Zh-QG. Pipeline (Xlm) first translates Chinese input to English, and then conduct En-En-QG with Xlm. As shown in Table TABREF20, human evaluation results indicate that Xnlg achieves significant improvements on the three metrics.\nWe use SQuAD 1.1 (Rajpurkar et al. 2016) as the English QG dataset.",

However, the obtained results are considerable and open the way in future to apply for the social media health text classification. Moreover, the performance of the LSTM based embedding for task 2 is good in comparison to the task 1. This is primarily due to the fact that the target classes of task 1 data set imbalanced. Hence, the proposed method can be applied on large number of tweets corpus in order to attain the best performance.\nRecently, the deep learning methods have performed well BIBREF8 and used in many tasks mainly due to that it doesn't rely on any feature engineering mechanism. However, the performance of deep learning methods implicitly relies on the large amount of raw data sets.

        "evidence": "Amdahl's law is often conflated with the law of diminishing returns, whereas only a special case of applying Amdahl's law demonstrates law of diminishing returns. If one picks optimally (in terms of the achieved speedup) what is to be improved, then one will see monotonically decreasing improvements as one improves. If, however, one picks non-optimally, after improving a sub-optimal component and moving on to improve a more optimal component, one can see an increase in the return. Note that it is often rational to improve a system in an order that is \"non-optimal\" in this sense, given that some improvements are more difficult or require larger development time than others.\n\nAmdahl's law does represent the law of diminishing returns if one is considering what sort of return one gets by adding more processors to a machine, if one is running a fixed-size computation that will use all available processors to their capacity. Each new processor added to the system will add less usable power than the previous one. Each time one doubles the number of processors the speedup ratio will diminish, as the total throughput heads toward the limit of 1/(1 − p).\n\nThis analysis neglects other potential bottlenecks such as memory bandwidth and I/O bandwidth. If these resources do not scale with the number of processors, then merely adding processors provides even lower returns.\n\nAn implication of Amdahl's law is that to speed up real applications which have both serial and parallel portions, heterogeneous computing techniques are required. There are novel speedup and energy consumption models based on a more general representation of heterogeneity, referred to as the normal form heterogeneity, that support a wide range of heterogeneous many-core architectures. These modelling methods aim to predict system power efficiency and performance ranges, and facilitates research and development at the hardware and system software levels.",

One of the weekly runs should be a long run. You can should start with a distance that you are able to currently run, and keep gradually increasing it every week until you are able to run 30 km. You shouldn't need training runs longer than that. You should be able to run 30 km about 6 weeks before your target marathon. In the last weeks before the marathon decrease it down to about 20 km.

        "evidence": "Water fluoridation is the controlled adjustment of fluoride to a public water supply solely to reduce tooth decay. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. Typically a fluoridated compound is added to drinking water, a process that in the U.S. costs an average of about $1.17 per person-year. Defluoridation is needed when the naturally occurring fluoride level exceeds recommended limits. In 2011, the World Health Organization suggested a level of fluoride from 0.5 to 1.5 mg/L (milligrams per litre), depending on climate, local environment, and other sources of fluoride.

Water fluoridation reduces cavities in children, while efficacy in adults is less clear. A Cochrane review estimates a reduction in cavities when water fluoridation was used by children who had no access to other sources of fluoride to be 35% in baby teeth and 26% in permanent teeth. However, this was based on older studies which failed to control for numerous variables, such as increasing sugar consumption as well as other dental strategies. Most European countries have experienced substantial declines in tooth decay, though milk and salt fluoridation is widespread in lieu of water fluoridation. Recent studies suggest that water fluoridation, particularly in industrialized nations, may be unnecessary because topical fluorides (such as in toothpaste) are widely used, and caries rates have become low.\n\nAlthough fluoridation can cause dental fluorosis, which can alter the appearance of developing teeth or enamel fluorosis, the differences are mild and usually not an aesthetic or public health concern. There is no clear evidence of other side effects from water fluoridation. Fluoride's effects depend on the total daily intake of fluoride from all sources. Drinking water is typically the largest source; other methods of fluoride therapy include fluoridation of toothpaste, salt, and milk. The views on the most efficient method for community prevention of tooth decay are mixed.

        "question": "List the name of the areas surrounding Greece and group by directions from the passage. List the results in comma separated format.",
        "evidence": "Greece, officially the Hellenic Republic, is a country in Southeast Europe. It is situated on the southern tip of the Balkan Peninsula, and is located at the crossroads of Europe, Asia, and Africa. Greece shares land borders with Albania to the northwest, North Macedonia and Bulgaria to the north, and Turkey to the northeast. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, and the Sea of Crete and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin, featuring thousands of islands. The country consists of nine traditional geographic regions, and has a population of approximately 10.5 million. Athens is the nation's capital and largest city, followed by Thessaloniki and Patras.\n\nGreece is considered the cradle of Western civilization, being the birthplace of democracy, Western philosophy, Western literature, historiography, political science, major scientific and mathematical principles, theatre and the Olympic Games. From the eighth century BC, the Greeks were organised into various independent city-states, known as poleis (singular polis), which spanned the Mediterranean and the Black Sea. Philip II of Macedon united most of present-day Greece in the fourth century BC, with his son Alexander the Great rapidly conquering much of the ancient world, from the eastern Mediterranean to the North Western parts of India. The subsequent Hellenistic period saw the height of Greek culture and influence in antiquity. Greece was annexed by Rome in the second century BC, becoming an integral part of the Roman Empire and its continuation, the Byzantine Empire, which was culturally and linguistically predominantly Greek. The Greek Orthodox Church, which emerged in the first century AD, helped shape modern Greek identity and transmitted Greek traditions to the wider Orthodox world. After falling under Ottoman rule in the mid-15th century, Greece emerged as a modern nation state in 1830 following a war of independence. Over the first hundred years the kingdom of Greece sought its territorial expansion, which was mainly achieved in the early 20th century, during the Balkan Wars and up until the catastrophe of Greece's Asia Minor Campaign in 1922. The short-lived republic that followed, beset by the ramifications of civil strife, came to an end in 1936, when the imposition of a royalist dictatorship inaugurated a long period of authoritarian rule, marked by military occupation during World War II, civil war and military dictatorship. Greece achieved record economic growth from 1950 through the 1970s, allowing it to join the ranks of developed nations. Democracy was restored in 1974–75, and Greece has been a parliamentary republic ever since. The country's rich historical legacy is reflected in part by its 18 UNESCO World Heritage Sites.",

Let $\\hat{G}$ be graph $G$ without the special document node, and matrix $\\mathbf {\\hat{H}}^T \\in \\mathbb {R}^{(n-1) \\times d}$ be the corresponding representation matrix (i.e., $\\mathbf {H}^T$ without the row of the document node).\nWe use as our READOUT function the concatenation of self-attention applied to $\\mathbf {\\hat{H}}^T$ with the final document node representation. More precisely, we apply a global self-attention mechanism BIBREF22 to the rows of $\\mathbf {\\hat{H}}^T$. As shown in Eq. DISPLAY_FORM17, $\\mathbf {\\hat{H}}^T$ is first passed to a dense layer parameterized by matrix $\\mathbf {W}_A^T \\in \\mathbb {R}^{d \\times d}$. An alignment vector $\\mathbf {a}$ is then derived by comparing, via dot products, the rows of the output of the dense layer $\\mathbf {Y}^T \\in \\mathbb {R}^{(n-1) \\times d}$ with a trainable vector $\\mathbf {v}^T \\in \\mathbb {R}^d$ (initialized randomly) and normalizing with a softmax. The normalized alignment coefficients are finally used to compute the attentional vector $\\mathbf {u}^T \\in \\mathbb {R}^d$ as a weighted sum of the final representations $\\mathbf {\\hat{H}}^T$.\n\n\nNote that we tried with multiple context vectors, i.e., with a matrix $\\mathbf {V}^T$ instead of a vector $\\mathbf {v}^T$, like in BIBREF22, but results were not convincing, even when adding a regularization term to the loss to favor diversity among the rows of $\\mathbf {V}^T$.\nMaster node skip connection. $\\mathbf {h}_G^T \\in \\mathbb {R}^{2d}$ is obtained by concatenating $\\mathbf {u}^T$ and the final master node representation. That is, the master node vector bypasses the attention mechanism. This is equivalent to a skip or shortcut connection BIBREF23. The reason behind this choice is that we expect the special document node to learn a high-level summary about the document, such as its size, vocabulary, etc. (more details are given in subsection SECREF30). Therefore, by making the master node bypass the attention layer, we directly inject global information about the document into its final representation.\nMulti-readout. BIBREF14, inspired by Jumping Knowledge Networks BIBREF12, recommend to not only use the final representations when performing readout, but also that of the earlier steps. Indeed, as one iterates, node features capture more and more global information. However, retaining more local, intermediary information might be useful too. Thus, instead of applying the readout function only to $t=T$, we apply it to all time steps and concatenate the results, finally obtaining $\\mathbf {h}_G \\in \\mathbb {R}^{T \\times 2d}$ :\n\nIn effect, with this modification, we take into account features based on information aggregated from subtrees of different heights (from 1 to $T$), corresponding to local and global features.\nMulti-readout. (Xu et al. 2018a), inspired by Jumping Knowledge Networks (Xu et al. 2018b), recommend to not only use the final representations when performing readout, but also that of the earlier steps.

        "answer": "EqEmbs provide more efficient modeling than existing word embedding methods.",
        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nWe found that EqEmbs provide more efficient modeling than existing word embedding methods.",

We mainly have two interesting observations and provide the corresponding explanations to them in Section 4.2.\nAs for different downstream tasks, we observe SSL models perform competitively to SL-JT models under many-shot evaluation while SSL models significantly underform SL-JT models under few-shot evaluation. The underlying insight is that supervised features are correlated with labels and more discriminative, thus easy to directly transfer to downstream datasets similar to upstream pre-training data (DomainNet or ImageNet). For example, SL models dominate most few-shot object or scene classification tasks but fail on DTD dataset, a texture classification dataset which shares no common classes with ImageNet or DomainNet. In contrast, self-supervised features are more generalized and comprehensive, thus requiring more fine-tuning for desirable downstream transfer.\nAs for evaluation with different downstream datasets, we find the sequentially trained model may suffer “negative transfer” on some specific downstream datasets. A concrete example is given in Appendix B.3. The insight behind pre-training with more data chunks does not necessarily benefit a specific downstream dataset if the added training data are irrelevant to the downstream dataset.\nIt is a great suggestion on the analysis of the affinities across tasks to further understand the downstream tasks.

The main difference between the two evaluation protocols is that linear evaluation involves more fine-tuning than few-shot evaluation, as introduced in Appendix A.4. Therefore, the underlying reason for the observation is that supervised features are correlated with labels and more discriminative, thus easy to directly transfer to downstream datasets similar to upstream pre-training data (DomainNet or ImageNet).

        "evidence": "Nowadays, dialog systems are usually designed for a single domain BIBREF0 . They store data in a well-defined format with a fixed number of attributes for entities that the system can provide. Because data in this format can be stored as a two-dimensional table within a relational database, we call the data flat. This data representation allows the system to query the database in a simple and efficient way. It also allows to keep the dialog state in the form of slots (which usually correspond to columns in the table) and track it through the dialog using probabilistic belief tracking BIBREF1 , BIBREF2 .\nHowever, the well-defined structure of the database of a typical dialog system comes with a high cost of extending it as every piece of new information has to fit the format. This is especially a problem when we one is adapting the system for a new domain because its entities could have different attributes.\nA dialog system based on knowledge bases offers many advantages. First, the knowledge base, which can be represented as knowledge graph containing entities connected by relations, is much more flexible than the relational database. Second, freely available knowledge bases, such as Freebase, Wikidata, etc. contain an enormous amount of structured information, and are still growing. A dialog system which is capable of working with this type of information would be therefore very useful.\nIn this paper we propose a dataset aiming to help develop and evaluate dialog systems based on knowledge bases by interactive learning motivated in Section \"Motivation\" Section \"Dialog policies\" describes policies that can be used for retrieving information from knowledge bases.

        "question": "What can be inferred from their novel method?",
        "answer": "Infers on both structured and unstructured resources.",
        "evidence": "Since the advent of large structured knowledge bases (KBs) like Freebase BIBREF0 , YAGO BIBREF1 and DBpedia BIBREF2 , answering natural language questions using those structured KBs, also known as KB-based question answering (or KB-QA), is attracting increasing research efforts from both natural language processing and information retrieval communities.\nThe state-of-the-art methods for this task can be roughly categorized into two streams. The first is based on semantic parsing BIBREF3 , BIBREF4 , which typically learns a grammar that can parse natural language to a sophisticated meaning representation language. But such sophistication requires a lot of annotated training examples that contains compositional structures, a practically impossible solution for large KBs such as Freebase. Furthermore, mismatches between grammar predicted structures and KB structure is also a common problem BIBREF4 , BIBREF5 , BIBREF6 .\nOn the other hand, instead of building a formal meaning representation, information extraction methods retrieve a set of candidate answers from KB using relation extraction BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 or distributed representations BIBREF11 , BIBREF12 . Designing large training datasets for these methods is relatively easy BIBREF7 , BIBREF13 , BIBREF14 . These methods are often good at producing an answer irrespective of their correctness. However, handling compositional questions that involve multiple entities and relations, still remains a challenge. Consider the question what mountain is the highest in north america. Relation extraction methods typically answer with all the mountains in North America because of the lack of sophisticated representation for the mathematical function highest. To select the correct answer, one has to retrieve all the heights of the mountains, and sort them in descending order, and then pick the first entry. We propose a method based on textual evidence which can answer such questions without solving the mathematic functions implicitly.\nKnowledge bases like Freebase capture real world facts, and Web resources like Wikipedia provide a large repository of sentences that validate or support these facts. For example, a sentence in Wikipedia says, Denali (also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. To answer our example question against a KB using a relation extractor, we can use this sentence as external evidence, filter out wrong answers and pick the correct one.\nUsing textual evidence not only mitigates representational issues in relation extraction, but also alleviates the data scarcity problem to some extent. Consider the question, who was queen isabella's mother. Answering this question involves predicting two constraints hidden in the word mother. One constraint is that the answer should be the parent of Isabella, and the other is that the answer's gender is female. Such words with multiple latent constraints have been a pain-in-the-neck for both semantic parsing and relation extraction, and requires larger training data (this phenomenon is coined as sub-lexical compositionality by wang2015). Most systems are good at triggering the parent constraint, but fail on the other, i.e., the answer entity should be female. Whereas the textual evidence from Wikipedia, ...her mother was Isabella of Barcelos ..., can act as a further constraint to answer the question correctly.\nWe present a novel method for question answering which infers on both structured and unstructured resources. Our method consists of two main steps as outlined in sec:overview. In the first step we extract answers for a given question using a structured KB (here Freebase) by jointly performing entity linking and relation extraction (sec:kb-qa). In the next step we validate these answers using an unstructured resource (here Wikipedia) to prune out the wrong answers and select the correct ones (sec:refine). Our evaluation results on a benchmark dataset WebQuestions show that our method outperforms existing state-of-the-art models. Details of our experimental setup and results are presented in sec:experiments.

        "evidence": "This paper describes our approach and results for Task 2 of the CoNLL–SIGMORPHON 2018 shared task on universal morphological reinflection BIBREF0 . The task is to generate an inflected word form given its lemma and the context in which it occurs.\nMorphological (re)inflection from context is of particular relevance to the field of computational linguistics: it is compelling to estimate how well a machine-learned system can capture the morphosyntactic properties of a word given its context, and map those properties to the correct surface form for a given lemma.\nThere are two tracks of Task 2 of CoNLL–SIGMORPHON 2018: in Track 1 the context is given in terms of word forms, lemmas and morphosyntactic descriptions (MSD); in Track 2 only word forms are available. See Table TABREF1 for an example. Task 2 is additionally split in three settings based on data size: high, medium and low, with high-resource datasets consisting of up to 70K instances per language, and low-resource datasets consisting of only about 1K instances.\nThe baseline provided by the shared task organisers is a seq2seq model with attention (similar to the winning system for reinflection in CoNLL–SIGMORPHON 2016, BIBREF1 ), which receives information about context through an embedding of the two words immediately adjacent to the target form. We use this baseline implementation as a starting point and achieve the best overall accuracy of 49.87 on Task 2 by introducing three augmentations to the provided baseline system: (1) We use an LSTM to encode the entire available context; (2) We employ a multi-task learning approach with the auxiliary objective of MSD prediction; and (3) We train the auxiliary component in a multilingual fashion, over sets of two to three languages.\nIn analysing the performance of our system, we found that encoding the full context improves performance considerably for all languages: 11.15 percentage points on average, although it also highly increases the variance in results. Multi-task learning, paired with multilingual training and subsequent monolingual finetuning, scored highest for five out of seven languages, improving accuracy by another 9.86% on average.\nIn analysing the performance of our system, we found that encoding the full context improves performance considerably for all languages: 11.15 percentage points on average, although it also highly increases the variance in results.",

        "question": "Does the Seq2Seq model achieve higher scores with filtered conversation as input?",
        "answer": "Yes, it does.",
        "evidence": "The experimental results of the detection task and the generative intervention task are shown in Table TABREF27 and Table TABREF29 separately. The results of the human evaluation are shown in Table TABREF30. Figure FIGREF25 shows examples of the generated responses.\nAs shown in Table TABREF27 and TABREF29, all the classification and generative models perform better on the Gab dataset than on the Reddit dataset. We think this stems from the datasets' characteristics. First, the Gab dataset is larger and has a more balanced category distribution than the Reddit dataset. Therefore, it is inherently more challenging to train a classifier on the Reddit dataset. Further, the average lengths of the Reddit posts and conversations are much larger than those of Gab, potentially making the Reddit input nosier than the Gab input for both tasks. On both the Gab and Reddit datasets, the SVM classifier and the LR classifier achieved better performance than the CNN and RNN model with randomly initialized word embeddings. A possible reason is that without pretrained word embeddings, the neural network models tend to overfit on the dataset.\nFor the generative intervention task, three models perform similarly on all three automatic evaluation metrics. As expected, the Seq2Seq model achieves higher scores with filtered conversation as input. However, this is not the case for the VAE model. This indicates that the two models may have different capabilities to capture important information in conversations.\nAs shown in Table TABREF29, applying Reinforcement Learning does not lead to higher scores on the three automatic metrics. However, human evaluation (Table TABREF30) shows that the RL model creates responses that are potentially better at mitigating hate speech and are more diverse, which is consistent with BIBREF21. There is a larger performance difference with the Gab dataset, while the effectiveness and the diversity of the responses generated by the Seq2Seq model and the RL model are quite similar on the Reddit dataset. One possible reason is that the size of the training data from Reddit (around 8k) is only 30% the size of the training data from Gab. The inconsistency between the human evaluation results and the automatic ones indicates the automatic evaluation metrics listed in Table TABREF29 can hardly reflect the quality of the generated responses. As mentioned in Section SECREF4, annotators tend to have strategies for intervention. Therefore, generating the common parts of the most popular strategies for all the testing input can lead to high scores of these automatic evaluation metrics. For example, generating “Please do not use derogatory language.” for all the testing Gab data can achieve 4.2 on BLEU, 20.4 on ROUGE, and 18.2 on METEOR. However, this response is not considered as high-quality because it is almost a universal response to all the hate speech, regardless of the context and topic.\nSurprisingly, the responses generated by the VAE model have much worse diversity than the other two methods according to human evaluation. As indicated in Figure FIGREF25, the responses generated by VAE tend to repeat the responses related to some popular hate keyword. For example, “Use of the r-word is unacceptable in our discourse as it demeans and insults people with mental disabilities.” and “Please do not use derogatory language for intellectual disabilities.” are the generated responses for a large part of the Gab testing data. According to Figure FIGREF20, insults towards disabilities are the largest portion in the dataset, so we suspect that the performance of the VAE model is affected by the imbalanced keyword distribution.\nThe sampled results in Figure FIGREF25 show that the Seq2Seq and the RL model can generate reasonable responses for intervention. However, as is to be expected with machine-generated text, in the other human evaluation we conducted, where Mechanical Turk workers were also presented with sampled human-written responses alongside the machine generated responses, the human-written responses were chosen as the most effective and diverse option a majority of the time (70% or more) for both datasets. This indicates that there is significant room for improvement while generating automated intervention responses.\nIn our experiments, we only utilized the text of the posts, but more information is available and can be utilized, such as the user information and the title of a Reddit submission.\nAs expected, the Seq2Seq model achieves higher scores with filtered conversation as input.",

The labeling on this dataset is non-standard, so we used the following mapping for labels:\nsadness INLINEFORM0 sadness\nworry INLINEFORM0 fear\nhappiness INLINEFORM0 joy\nlove INLINEFORM0 love\nsurprise INLINEFORM0 surprise\nanger INLINEFORM0 anger\nWe then classified emotions using the pre-trained models and emotionally fitted fastText embedding. The result can be seen in Table TABREF19 . The baseline results are from BIBREF33 done using BOW model and maximum entropy classifier. We saw a huge improvement from 26 point increase in F-measure for the emotion joy (happiness) up to 57 point increase for surprise with total average increase of 38.6 points. Bostan and Klinger did not report classification results for the emotion love so we did not include it in the average. These results show that our trained models perform exceptionally on a totally new dataset with a different method of annotation.\nTo asses the performance of these models on a totally unseen data, we tried to classify the CrowdFlower emotional tweets dataset.

It is briefly described in The Federal Reserve System‍—‌Purposes and Functions as follows:\n\nBy creating the Federal Reserve System, Congress intended to eliminate the severe financial crises that had periodically swept the nation, especially the sort of financial panic that occurred in 1907. During that episode, payments were disrupted throughout the country because many banks and clearinghouses refused to clear checks drawn on certain other banks, a practice that contributed to the failure of otherwise solvent banks. To address these problems, Congress gave the Federal Reserve System the authority to establish a nationwide check-clearing system. The System, then, was to provide not only an elastic currency‍—‌that is, a currency that would expand or shrink in amount as economic conditions warranted‍—‌but also an efficient and equitable check-collection system.",

As more than one user may interact with a given post, we first add a maximum pooling layer after the user matrix embedding layer and user vector embedding layer to form a moderator matrix embedding INLINEFORM0 and a moderator vector embedding INLINEFORM1 for moderator INLINEFORM2 respectively, where INLINEFORM3 is used for the semantic transformation in the document composition process, as mentioned in the previous section. The term moderator here is to denote the pseudo user who provides the overall semantic/sentiment of all the engaged users for one document. The embedding INLINEFORM4 models the moderator stance preference, that is, the pattern of the revealed user stance: whether a user is willing to show his preference, whether a user likes to show impartiality with neutral statements and reasonable arguments, or just wants to show strong support for one stance. Ideally, the latent user stance is modeled by INLINEFORM5 for each user. Likewise, for topic information, a maximum pooling layer is added after the topic matrix embedding layer and topic vector embedding layer to form a joint topic matrix embedding INLINEFORM6 and a joint topic vector embedding INLINEFORM7 for topic INLINEFORM8 respectively, where INLINEFORM9 models the semantic transformation of topic INLINEFORM10 as in users and INLINEFORM11 models the topic stance tendency. The latent topic stance is also modeled by INLINEFORM12 for each topic.\nAs for comments, we view them as short documents with authors only but without likers nor their own comments. Therefore we apply document composition on comments although here users are commenters (users who comment). It is noticed that the word embeddings INLINEFORM0 for the same word in the posts and comments are the same, but after being transformed to INLINEFORM1 in the document composition process shown in Figure FIGREF4 , they might become different because of their different engaged users. The output comment representation together with the commenter vector embedding INLINEFORM2 and topic vector embedding INLINEFORM3 are concatenated and a maximum pooling layer is added to select the most important feature for comments. Instead of requiring that the comment stance agree with the post, UTCNN simply extracts the most important features of the comment contents; they could be helpful, whether they show obvious agreement or disagreement. Therefore when combining comment information here, the maximum pooling layer is more appropriate than other pooling or merging layers. Indeed, we believe this is one reason for UTCNN's performance gains.\nFinally, the pooled comment representation, together with user vector embedding INLINEFORM0 , topic vector embedding INLINEFORM1 , and document representation are fed to a fully connected network, and softmax is applied to yield the final stance label prediction for the post.\nFigure 2 illustrates the UTCNN model. As more than one user may interact with a given post, we first add a maximum pooling layer after the user matrix embedding layer and user vector embedding layer to form a moderator matrix embedding Uk and a moderator vector embedding uk for moderator k respectively, where Uk is used for the semantic transformation in the document composition process, as mentioned in the previous section.",

The length and difficulty of the trail used to keep it less crowded than other park trails, but in recent years the trail traffic has grown to as many as 800 people a day. The hike can be done from the valley floor in a single long day, but many people break it up by camping overnight in Little Yosemite Valley. The trail climbs past Vernal Fall and Nevada Fall, then continues into Little Yosemite Valley, then north to the base of the northeast ridge of Half Dome itself.\n\nThe final 400 ft (120 m) ascent is steeply up the rock between two steel cables used as handholds. The cables are fixed with bolts in the rock and raised onto a series of metal poles in late May (the poles do not anchor the cables). The cables are taken down from the poles for the winter in early October, but they are still fixed to the rock surface and can be used. The National Park Service recommends against climbing the route when the cables are down or when the surface of the rock is wet and slippery. The Cable Route is rated class 3, while the same face away from the cables is rated class 5.\n\n\nThe Cable Route gets crowded on the weekends\nThe Cable Route can be crowded. In past years, as many as 1,000 hikers per day have climbed the dome on a summer weekend, and about 50,000 hikers climb it every year.\n\nSince 2011, all hikers who intend to ascend the Cable Route must now obtain permits before entering the park when the cables are up between May and October. Permits are checked by a ranger on the trail, and no hikers without permits are allowed to hike beyond the base of the sub-dome or to the bottom of the cables. Hikers caught bypassing the rangers to visit either the sub-dome or main dome without a permit face fines of up to $5,000 and/or 6 months in jail.\n\nBackpackers with an appropriate wilderness permit can receive a Half Dome permit when they pick up their wilderness permit with no additional reservation required. Rock climbers who reach the top of Half Dome without entering the subdome area can descend on the Half Dome Trail without a permit.\n\nThe top of Half Dome is a large, flat area where climbers can relax and enjoy their accomplishment.

A notable location to one side of Half Dome is the \"Diving Board\", where Ansel Adams took his photograph Monolith, the Face of Half Dome on April 10, 1927. Often confused with \"the Visor,\" a small overhanging ledge at the summit, the Diving Board is on the shoulder of Half Dome.\n\nFrom 1919 when the cables were erected through 2011, there have been seven fatal falls from the cables. The latest fatality occurred on September 5, 2019.\n\nLightning strikes can be a risk while on or near the summit.

        "evidence": "",
        "answer": "For one thing, it does a fantastic job of making the crew of the Nostromo relatable and human. We spend a lot of time with them before any seriously suspenseful or horrific things happen. We understand they're a tight crew, and care about each other, and that they already feel some animosity towards the mining company that sent them out into space. This makes it a lot more scary and sad when eventually most of them become prey to the alien.\n\nSecondly, the main villain in Alien is not only way scarier than almost any other creature villain ever made, the way they build up both her backstory and her eventual full reveal is amazing. When we first see the small chestburster alien, neither we nor the crew have any idea how big, terrifying, and lethal she will become. From her sticky, slick sheen to her cunning and silent hunting skills, she is truly an unstoppable force. If I were trapped on a spaceship with that creature, I don't know what I'd do.\n\nAnd finally, Alien just feels more \"real\" with its universal and timely themes of greed and fear of the unknown. There are numerous actual stories of mining companies betraying their field employees and endangering their lives for a quick buck; isolated teams of workers going crazy,  suffering from unseen maladies, and falling into chaos and disarray; and of course, the tale of predator and prey is perhaps the oldest one of all.

Our model achieves significant performance gains in the test sets over the baseline for both Italian and Finnish query translation. The overall low MAP for NMT can possibly be improved with larger TC. Moreover, our model validation approach requires access to RC index, and it slows down overall training process. Hence, we could not train our model for a large number of epochs - it may be another cause of the low performance.\nWe want to show that translation terms generated by our multi-task transformer are roughly equally likely to be seen in the Europarl corpus (TC) or the CLEF corpus (RC). Given a translation term INLINEFORM0 , we compute the ratio of the probability of seeing INLINEFORM1 in TC and RC, INLINEFORM2 . Here, INLINEFORM3 and INLINEFORM4 is calculated similarly. Given a query INLINEFORM5 and its translation INLINEFORM6 provided by model INLINEFORM7 , we calculate the balance of INLINEFORM8 , INLINEFORM9 . If INLINEFORM10 is close to 1, the translation terms are as likely in TC as in RC. Figure FIGREF15 shows the balance values for transformer and our model for a random sample of 20 queries from the validation set of Italian queries, respectively. Figure FIGREF16 shows the balance values for transformer and our model for a random sample of 20 queries from the test set of Italian queries, respectively. It is evident that our model achieves better balance compared to baseline transformer, except for a very few cases.\nGiven a query INLINEFORM0 , consider INLINEFORM1 as the set of terms from human translation of INLINEFORM2 and INLINEFORM3 as the set of translation terms generated by model INLINEFORM4 . We define INLINEFORM5 and INLINEFORM6 as precision and recall of INLINEFORM7 for model INLINEFORM8 . In Table TABREF19 , we report average precision and recall for both transformer and our model across our train and validation query set over two language pairs. Our model generates precise translation, i.e. it avoids terms that might be useless or even harmful for retrieval. Generally, from our observation, avoided terms are highly likely terms from TC and they are generated because of translation model overfitting. Our model achieves a regularization effect through an auxiliary task. This confirms results from existing multi-tasking literature BIBREF15 .\nTo explore translation quality, consider pair of sample translations provided by two models. For example, against an Italian query, medaglia oro super vinse medaglia oro super olimpiadi invernali lillehammer, translated term set from our model is {gold, coin, super, free, harmonising, won, winter, olympics}, while transformer output is {olympic, gold, one, coin, super, years, won, parliament, also, two, winter}. Term set from human translation is: {super, gold, medal, won, lillehammer, olypmic, winter, games}. Transformer comes up with terms like parliament, also, two and years that never appears in human translation. We found that these terms are very likely in Europarl and rare in CLEF. Our model also generates terms such as harmonising, free, olympics that not generated by transformer. However, we found that these terms are equally likely in Europarl and CLEF.\nWe want to show that translation terms generated by our multi-task transformer are roughly equally likely to be seen in the Europarl corpus (TC) or the CLEF corpus (RC).",

Apple created the device during a secretive collaboration with Cingular Wireless (later renamed AT&T Mobility) at the time—at an estimated development cost of US$150 million over thirty months. According to Jobs in 1998, the \"i\" word in \"iMac\" (and therefore \"iPod\", \"iPhone\" and \"iPad\") stands for internet, individual, instruct, inform, and inspire.\n\nApple rejected the \"design by committee\" approach that had yielded the Motorola ROKR E1, a largely unsuccessful \"iTunes phone\" made in collaboration with Motorola. Among other deficiencies, the ROKR E1's firmware limited storage to only 100 iTunes songs to avoid competing with Apple's iPod nano. Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house, a rare practice at the time, and paid Apple a fraction of its monthly service revenue (until the iPhone 3G), in exchange for four years of exclusive U.S. sales, until 2011.\n\nJobs unveiled the first-generation iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Center in San Francisco. The iPhone incorporated a 3.5-inch multi-touch display with few hardware buttons, and ran the iPhone OS operating system with a touch-friendly interface, then marketed as a version of Mac OS X. It launched on June 29, 2007, at a starting price of US$499 in the United States, and required a two-year contract with AT&T.\n\n\nWorldwide iPhone availability:\n  iPhone available since its original release\n  iPhone available since the release of iPhone 3G\nOn July 11, 2008, at Apple's Worldwide Developers Conference (WWDC) 2008, Apple announced the iPhone 3G, and expanded its launch-day availability to twenty-two countries, and it was eventually released in 70 countries and territories. The iPhone 3G introduced faster 3G connectivity, and a lower starting price of US$199 (with a two-year AT&T contract). Its successor, the iPhone 3GS, was announced on June 8, 2009, at WWDC 2009, and introduced video recording functionality.\n\n\nFirst iPhone on display under glass at the January 2007 Macworld show\nThe iPhone 4 was announced on June 7, 2010, at WWDC 2010, and introduced a redesigned body incorporating a stainless steel frame and a rear glass panel. At release, the iPhone 4 was marketed as the \"world's thinnest smartphone\"; it uses the Apple A4 processor, being the first iPhone to use an Apple custom-designed chip. It introduced the Retina display, having four-times the display resolution of preceding iPhones, and was the highest-resolution smartphone screen at release; a front-facing camera was also introduced, enabling video calling functionality via FaceTime.\n\nUsers of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way, and this issue was nicknamed \"antennagate\". In January 2011, as Apple's exclusivity agreement with AT&T was expiring, Verizon announced that they would be carrying the iPhone 4, with a model compatible with Verizon's CDMA network releasing on February 10",

        "question": "What is improved by their proposed approach significantly?",
        "answer": "The domain classification.",
        "evidence": "Domain classification is a task that predicts the most relevant domain given an input utterance BIBREF0. It is becoming more challenging since recent conversational interaction systems such as Amazon Alexa, Google Assistant, and Microsoft Cortana support more than thousands of domains developed by external developers BIBREF3, BIBREF2, BIBREF4. As they are independently and rapidly developed without a centralized ontology, multiple domains have overlapped capabilities that can process the same utterances. For example, “make an elephant sound” can be processed by AnimalSounds, AnimalNoises, and ZooKeeper domains.\nSince there are a large number of domains, which are even frequently added or removed, it is infeasible to obtain all the ground-truth domains of the training utterances, and domain classifiers for conversational interaction systems are usually trained given only a small number (usually one) of ground-truths in the training utterances. This setting corresponds to multi-label positive and unlabeled (PU) learning, where assigned labels are positive, unassigned labels are not necessarily negative, and one or more labels are assigned for an instance BIBREF5, BIBREF6.\nIn this paper, we utilize user log data, which contain triples of an utterance, the predicted domain, and the response, for the model training. Therefore, we are given only one ground-truth for each training utterance. In order to improve the classification performance in this setting, if certain domains are repeatedly predicted with the highest confidences even though they are not the ground-truths of an utterance, we regard the domains as additional pseudo labels. This is closely related to pseudo labeling BIBREF7 or self-training BIBREF8, BIBREF9, BIBREF10. While the conventional pseudo labeling is used to derive target labels for unlabeled data, our approach adds pseudo labels to singly labeled data so that the data can have multiple target labels. Also, the approach is related to self-distillation, which leverages the confidence scores of the non-target outputs to improve the model performance BIBREF11, BIBREF12. While distillation methods utilize the confidence scores as the soft targets, pseudo labeling regards high confident outputs as the hard targets to further boost their confidences. We use both pseudo labeling and self-distillation in our work.\nPseudo labels can be wrongly derived when irrelevant domains are top predicted, which can lead the model training with wrong supervision. To mitigate this issue, we leverage utterances with negative system responses to lower the prediction confidences of the failing domains. For example, if a system response of a domain for an input utterance is “I don't know that one”, the domain is regarded as a negative ground-truth since it fails to handle the utterance.\nEvaluating on an annotated dataset from the user logs of a large-scale conversation interaction system, we show that the proposed approach significantly improves the domain classification especially when hypothesis reranking is used BIBREF13, BIBREF4.\nEvaluating on an annotated dataset from the user logs of a large-scale conversation interaction system, we show that the proposed approach significantly improves the domain classification especially when hypothesis reranking is used [14, 5].",

OOV word representation is tested through qualitative nearest-neighbor analysis.\nAll models are trained using a 2015 dump of Wikipedia, lowercased and using only alphanumeric characters. Vocabulary is limited to words that appear at least 100 times for a total of 303517 words. Morfessor is trained on this vocabulary list.\nWe train the standard LexVec (LV), LexVec using n-grams (LV-N), and LexVec using unsupervised morphemes (LV-M) using the same hyper-parameters as BIBREF7 ( $\\textnormal {window} = 2$ , $\\textnormal {initial learning rate} = .025$ , $\\textnormal {subsampling} = 10^{-5}$ , $\\textnormal {negative samples} = 5$ , $\\textnormal {context distribution smoothing} = .75$ , $\\textnormal {positional contexts} = \\textnormal {True}$ ).\nBoth Skip-gram (SG) and fastText (FT) are trained using the reference implementation of fastText with the hyper-parameters given by BIBREF6 ( $\\textnormal {window} = 5$ , $\\textnormal {initial learning rate} = .025$ , $\\textnormal {subsampling} = 10^{-4}$ , $\\textnormal {negative samples} = 5$ ).\nAll five models are run for 5 iterations over the training corpus and generate 300 dimensional word representations.

Relationships are measured using the Google semantic (GSem) and syntactic (GSyn) analogies BIBREF2 and the Microsoft syntactic analogies (MSR) dataset BIBREF30 .\nWe also evaluate all five models on downstream tasks from the VecEval suite BIBREF13 , using only the tasks for which training and evaluation data is freely available: chunking, sentiment and question classification, and natural language identification (NLI).

As the use of these markets becomes more widespread, the use of self-branding and marketing tools will grow in importance.

Certainly, however, more works remains to be done in this field, and recent developments in unsupervised generative models already promise possible extensions to our analysis.\nFor example, since the introduction of GANs, research groups have studied how variational autoencoders can be incorporated into these models, to increase the clarity and accuracy of the models’ outputs. Wang et al. in particular demonstrate how using a variational autoencoder in the generator model can increase the accuracy of generated text samples [11]. Most promisingly, the data used by the group was a large data set of Amazon customer reviews, which in many ways parallels the tone and semantic structure of Airbnb listing descriptions. More generally, Bowman et al. demonstrate how the use of variational autoencoders presents a more accurate model for text generation, as compared to standard recurrent neural network language models [1].\nFor future work, we may also consider experimenting with different forms of word embeddings, such as improved word vectors (IWV) which were suggested by Rezaeinia et al [10].

We work with such a corpus of Russian and Ukrainian academic texts, initially collected for the purposes of cross-lingual plagiarism detection. This data is available online through a number of library services, but unfortunately cannot be republished due to copyright limitations.\nThe Ukrainian subcorpus contains about 60 thousand extended summaries (Russian and Ukrainian russian`автореферат', `avtoreferat') of theses submitted between 1998 and 2011. The Russian subcorpus is smaller in the number of documents (about 16 thousand, approximately the same time period), but the documents are full texts of theses, thus the total volume of the Russian subcorpus is notably larger: 830 million tokens versus 250 million tokens in the Ukrainian one. Generally, the texts belong to one genre that can be defined as post-Soviet expository academic prose, submitted for academic degree award process.\nThe documents were converted to plain text files from MS Word format in the case of the Ukrainian subcorpus and mainly from OCRed PDF files in the case of the Russian subcorpus. Because of this, the Russian documents often suffer from OCR artifacts, such as words split with line breaks, incorrectly recognized characters and so on. However, it does not influence the resulting model much, as we show below.\nBoth Ukrainian and Russian documents come with meta data allowing to separate them into academic fields, with economics, medicine and law being most frequent topics for the Ukrainian data and economics, history and pedagogy dominating the Russian data.\nFor evaluation, 3 topics were used, distant enough from each other and abundantly presented in both subcorpora: economics, law and history. We randomly selected 100 texts in each language for each topic. As an average length of Russian texts is significantly higher (them being full theses), we cropped them, leaving only the first 5 thousand words, to mimic the size of the Ukrainian summaries.

In the early 1980s mass-produced digital synthesizers, such as the Yamaha DX7, became popular, and MIDI (Musical Instrument Digital Interface) was developed. In the same decade, with a greater reliance on synthesizers and the adoption of programmable drum machines, electronic popular music came to the fore.

        "question": "What's the usage of NER?",
        "answer": "NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extractio, machine translation, question answering and knowledge base construction.",
        "evidence": "Named entity recognition (NER) BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc. NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction BIBREF4 , machine translation BIBREF5 , question answering BIBREF6 and knowledge base construction BIBREF7 . Although early NER systems have been successful in producing adequate recognition accuracy, they often require significant human effort in carefully designing rules or features.\nIn recent years, deep learning methods been employed in NER systems, yielding state-of-the-art performance. However, the number of types detected are still not sufficient for certain domain-specific applications. For relation extraction, identifying fine-grained types has been shown to significantly increase the performance of the extractor BIBREF8 , BIBREF9 since this helps in filtering out candidate relation types which do not follow this type constraint. Furthermore, for question answering fine-grained Named Entity Recognition (FgNER) can provide additional information helping to match questions to its potential answers thus improving performance BIBREF10 . For example, Li and Roth BIBREF11 rank questions based on their expected answer types (i.e. will the answer be food, vehicle or disease).\nTypically, FgNER systems use over a hundred labels, arranged in a hierarchical structure. We find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process. Furthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task. Currently, FgNER systems use distant supervision BIBREF12 to automatically generate training data. Distant supervision is a technique which maps each entity in the corpus to knowledge bases such as Freebase BIBREF13 , DBpedia BIBREF14 , YAGO BIBREF15 and helps with the generation of labeled data. This method will assign the same set of labels to all mentions of a particular entity in the corpus. For example, “Barack Obama” is a person, politician, lawyer, and author. If a knowledge base has these four matching labels, the distant supervision technique will assign all of them to every mention of “Barack Obama”. Therefore, the training data will also fail to distinguish between mentions of “Barack Obama” in all subsequent utterances.\nLing et al. ling2012fine proposed the first system for FgNER, where they used 112 overlapping labels with a linear classifier perceptron for multi-label classification. Yosef et al. spaniol2012hyena used multiple binary SVM classifiers to assign entities to a set of 505 types. Gillick et al. gillick2014context introduced context dependent FgNER and proposed a set of heuristics for pruning labels that might not be relevant given the local context of the entity. Yogatama et al. yogatama2015embedding proposed an embedding based model where user-defined features and labels were embedded into a low dimensional feature space to facilitate information sharing among labels.\nShimaoka et al. shimaoka2016attentive proposed an attentive neural network model which used long short-term memory (LSTMs) to encode the context of the entity, then used an attention mechanism to allow the model to focus on relevant expressions in the entity mention's context. To learn entity representations, we propose a scheme which is potentially more generalizable.\nNER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction (Mintz et al., 2009), machine translation (Koehn et al., 2007), question answering (Lin et al., 2012) and knowledge base construction (Dong et al., 2014).",

        "evidence": "The task of interpreting and following natural language (NL) navigation instructions involves interleaving different signals, at the very least the linguistic utterance and the representation of the world. For example, in turn right on the first intersection, the instruction needs to be interpreted, and a specific object in the world (the intersection) needs to be located in order to execute the instruction. In NL navigation studies, the representation of the world may be provided via visual sensors BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4 or as a symbolic world representation. This work focuses on navigation based on a symbolic world representation (referred to as a map).\nPrevious datasets for NL navigation based on a symbolic world representation, HCRC BIBREF5, BIBREF6, BIBREF7 and SAIL BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15 present relatively simple worlds, with a small fixed set of entities known to the navigator in advance. Such representations bypass the great complexity of real urban navigation, which consists of long paths and an abundance of previously unseen entities of different types.\nIn this work we introduce Realistic Urban Navigation (RUN), where we aim to interpret navigation instructions relative to a rich symbolic representation of the world, given by a real dense urban map. To address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes. Using Amazon Mechanical Turk, we collected 2515 instructions over 3 regions of Manhattan, all specified (and verified) by (respective) sets of humans workers. This task raises several challenges. First of all, we assume a large world, providing long routes, vulnerable to error propagation; secondly, we assume a rich environment, with entities of various different types, most of which are unseen during training and are not known in advance; finally, we evaluate on the full route intended, rather than on last-position only.\nWe then propose a strong neural baseline for RUN where we augment a standard encoder-decoder architecture with an entity abstraction layer, attention over words and worlds, and a constantly updating world-state. Our experimental results and ablation study show that this architecture is indeed better-equipped to treat grounding in realistic urban settings than standard sequence-to-sequence architectures. Given this RUN benchmark, empirical results, and evaluation procedure, we hope to encourage further investigation into the topic of interpreting NL instructions in realistic and previously unseen urban domains.\n[1]The task defined by BIBREF6 is of moving between entities only.\nTo address RUN, we designed and collected a new dataset based on OpenStreetMap, in which we align NL instructions to their corresponding routes.",

        "answer": "Following the success of the first film, Paramount Pictures began developing a follow-up, with many of the cast and crew returning. Coppola, who was given more creative control, had wanted to make both a sequel and a prequel to The Godfather that would tell the story of the rise of Vito and the fall of Michael. Principal photography began in October 1973 and wrapped up in June 1974. The Godfather Part II premiered in New York City on December 12, 1974, and was released in the United States on December 20, 1974, receiving divided reviews from critics; its reputation, however, improved rapidly, and it soon became the subject of critical re-appraisal. It grossed $48 million in the United States and Canada and up to $93 million worldwide on a $13 million budget. The film was nominated for eleven Academy Awards, and became the first sequel to win Best Picture. Its six Oscar wins also included Best Director for Coppola, Best Supporting Actor for De Niro and Best Adapted Screenplay for Coppola and Puzo. Pacino won Best Actor at the BAFTAs and was nominated at the Oscars.\n\nLike its predecessor, Part II remains a highly influential film, especially in the gangster genre. It is considered to be one of the greatest films of all time, as well as the rare example of a sequel that may be superior to its predecessor. In 1997, the American Film Institute ranked it as the 32nd-greatest film in American film history and it retained this position 10 years later. It was selected for preservation in the U.S. National Film Registry of the Library of Congress in 1993, being deemed \"culturally, historically, or aesthetically significant\".

        "answer": "Our major difference is that we devise a waypoint-oriented representation instead of trying to estimate the exact 3D coordinates of each object in the scene. Each object in our representation is constructed by the associated location from where the agent can interact with it (illustrated in Figure 2). This is easier to obtain and better suited for the downstream object interaction tasks than directly estimating the locations of all objects. To acquire such a map we handle large and small objects differently as described in Sec. 4.2.",
        "evidence": "Recent progress in Embodied Artificial Intelligence, spans both simulation environments;;;; and sophisticated tasks;;. Our work is most closely related to research in language-guided task completion, Neural SLAM, and exploration.\nLanguage-Guided Task Completion. is a benchmark that enables a learning agent to follow natural language descriptions to complete complex household tasks. The agent's goal is to learn a mapping from natural language instructions to a sequence of actions for task completion in a simulated 3D environment. Various modeling approaches have been proposed falling into roughly two families of methods. The first focuses on learning large end-to-end models that directly translate instructions to low-level agent actions;. However, these agents typically suffer from poor generalization performance, and are difficult to interpret. Recently, hierarchical approaches Zhang & Chai (2021); have attracted attention due to their better generalization and interpretability. We also adopt a hierarchical structure, focusing on affordance-aware navigation thereby achieving significantly better generalization than all existing approaches.\nNeural SLAM and Affordance-aware Semantic Representation. Neural SLAM, constructs an environment semantic representation enabling map-based long-horizon planning. However, these are tested in pure navigation tasks instead of complex household tasks, and does not consider affordance;, which is required for tasks involving both navigation and manipulations. In, the authors utilize SLAM for 3D environment reconstruction in language-guided task completion. Their approach relies heavily on accurate depth prediction (less robust in unseen environments). Instead, we propose a waypoint-oriented representation which associates each object with the locations on the floor from where the agent can interact with the object. Furthermore, different from the 2D affordance map in that directly predicts affordance type, our semantic representation supports more fine-grained control of the robot's position and pose, which facilitates significantly better generalization. The approach in assumes direct access to the ground truth depth information (not available in our setup) and the method in only focuses on pure navigation problems. approaches reward visiting all navigable areas by searching in a task-agnostic manner. In contrast, we propose a multimodal exploration approach utilizing egocentric visual input, language instructions, and memory of explored areas to reduce task-specific uncertainty of points of interest (areas important to complete the task). We show this to be more efficient, leading to more effective map prediction and robust planning.\nHowever, these are tested in pure navigation tasks instead of complex household tasks, and does not consider affordance Qi et al. (2019); Nagarajan & Grauman (2020); Xu et al. (2020), which is required for tasks involving both navigation and manipulations. In Blukis et al.

Two waypoints (drawn in white stars and arrows) are displayed for side table (∈ large object) and lettuce (∈ small object), respectively.

A Democrat from Texas, Johnson also served as a U.S. representative, U.S. Senator and the Senate's majority leader. He holds the distinction of being one of the few presidents who served in all elected offices at the federal level.\n\nBorn in a farmhouse in Stonewall, Texas, to a local political family, Johnson worked as a high school teacher and a congressional aide before winning election to the U.S. House of Representatives in 1937. In 1948, he won the 1948 Senate election in Texas after a narrow and controversial victory in the Democratic Party's primary. He was appointed to the position of Senate Majority Whip in 1951. He became the Senate Democratic leader in 1953 and majority leader in 1954. In 1960 Johnson ran for the Democratic nomination for president. Ultimately, Senator Kennedy bested Johnson and his other rivals for the nomination, then surprised many by offering to make Johnson his vice presidential running mate. The Kennedy-Johnson ticket won in the 1960 presidential election. Vice President Johnson assumed the presidency on November 22, 1963, after President Kennedy was assassinated. The following year Johnson was elected to the presidency when he won in a landslide against Arizona Senator Barry Goldwater, receiving 61.1% of the popular vote in the 1964 presidential election, the largest share won by any presidential candidate since the 1820 election.\n\nJohnson's domestic policy was aimed at expanding civil rights, public broadcasting, access to healthcare, aid to education and the arts, urban and rural development, and public services. In 1964 Johnson coined the term the \"Great Society\" to describe these efforts. In addition, he sought to create better living conditions for low-income Americans by spearheading a campaign unofficially called the \"War on Poverty\". As part of these efforts, Johnson signed the Social Security Amendments of 1965, which resulted in the creation of Medicare and Medicaid. Johnson followed his predecessor's actions in bolstering NASA and made the Apollo Program a national priority. He enacted the Higher Education Act of 1965 which established federally insured student loans. Johnson signed the Immigration and Nationality Act of 1965 which laid the groundwork for U.S. immigration policy today. Johnson's opinion on the issue of civil rights put him at odds with other white, southern Democrats. His civil rights legacy was shaped by signing the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Civil Rights Act of 1968. During his presidency, the American political landscape transformed significantly, as white southerners who were once staunch Democrats began moving to the Republican Party and black voters began moving to the Democratic Party. Because of his domestic agenda, Johnson's presidency marked the peak of modern liberalism in the United States.\n\nJohnson's presidency took place during the Cold War, thus his foreign policy prioritized containment of communism. Prior to his presidency, the U.S. was already involved in the Vietnam War, supporting South Vietnam against the communist North. Following a naval skirmish in 1964 between the United States and North Vietnam, Congress passed the Gulf of Tonkin Resolution, which granted Johnson the power to launch a full-scale military intervention in South East Asia. The number of American military personnel in Vietnam increased dramatically, and casualties soared among U.S. soldiers and Vietnamese civilians. Johnson also expanded military operations in neighboring Laos to destroy North Vietnamese supply lines. In 1968, the communist Tet Offensive inflamed the anti-war movement, especially among draft-age students on university campuses, and public opinion turned against America's involvement in the war. In Europe, Johnson's administration continued to promote and foster Western European political and economic cooperation and integration as his predecessors had.\n\nAt home, Johnson faced further troubles with race riots in major cities and increasing crime rates. His political opponents seized the opportunity and raised demands for \"law and order\" policies. Johnson began his presidency with near-universal support, but his approval declined throughout his presidency as the public became frustrated with both the Vietnam War and domestic unrest. Johnson initially sought to run for re-election; however, following disappointing results in the New Hampshire primary he withdrew his candidacy. The war was a major election issue and the 1968 presidential election saw Republican candidate Richard Nixon defeat Johnson's vice president Hubert Humphrey. At the end of his presidency in 1969, Johnson returned to his Texas ranch, published his memoirs, and in other respects kept a low profile until he died of a heart attack in 1973.\n\nJohnson is one of the most controversial presidents in American history. Public opinion and academic assessments of his legacy have fluctuated greatly ever since his death. Historians and scholars rank Johnson in the upper tier because of his accomplishments regarding domestic policy. His administration passed many major laws that made substantial changes in civil rights, health care, welfare, and education. Conversely, Johnson is strongly criticized for his foreign policy, namely escalating American involvement in the Vietnam War.",

        "question": "Is the natural language crucial in the planning of an agent?",
        "answer": "Yes, it is.",
        "evidence": "Negotiations, either between individuals or entities, are ubiquitous in everyday human interactions ranging from sales to legal proceedings. Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nRather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well.",

        "question": "What is the hypothesis of the paper?",
        "answer": "The source code of the entire Java class contains more information than just the commit diff and could potentially improve the identification of security-relevant commits.",
        "evidence": "The use of open-source software has been steadily increasing for some time now, with the number of Java packages in Maven Central doubling in 2018. However, BIBREF0 states that there has been an 88% growth in the number of vulnerabilities reported over the last two years. In order to develop secure software, it is essential to analyze and understand security vulnerabilities that occur in software systems and address them in a timely manner. While there exist several approaches in the literature for identifying and managing security vulnerabilities, BIBREF1 show that an effective vulnerability management approach must be code-centric. Rather than relying on metadata, efforts must be based on analyzing vulnerabilities and their fixes at the code level.\nCommon Vulnerabilities and Exposures (CVE) is a list of publicly known cybersecurity vulnerabilities, each with an identification number. These entries are used in the National Vulnerability Database (NVD), the U.S. government repository of standards based vulnerability management data. The NVD suffers from poor coverage, as it contains only 10% of the open-source vulnerabilities that have received a CVE identifier BIBREF2. This could be due to the fact that a number of security vulnerabilities are discovered and fixed through informal communication between maintainers and their users in an issue tracker. To make things worse, these public databases are too slow to add vulnerabilities as they lag behind a private database such as Snyk's DB by an average of 92 days BIBREF0 All of the above pitfalls of public vulnerability management databases (such as NVD) call for a mechanism to automatically infer the presence of security threats in open-source projects, and their corresponding fixes, in a timely manner.\nWe propose a novel approach using deep learning in order to identify commits in open-source repositories that are security-relevant. We build regularized hierarchical deep learning models that encode features first at the file level, and then aggregate these file-level representations to perform the final classification. We also show that code2vec, a model that learns from path-based representations of code and claimed by BIBREF3 to be suitable for a wide range of source code classification tasks, performs worse than our logistic regression baseline.\nIn this study, we seek to answer the following research questions:\n[leftmargin=*]\nRQ1: Can we effectively identify security-relevant commits using only the commit diff? For this research question, we do not use any of the commit metadata such as the commit message or information about the author. We treat source code changes like unstructured text without using path-based representations from the abstract syntax tree.\nRQ2: Does extracting class-level features before and after the change instead of using only the commit diff improve the identification of security-relevant commits? For this research question, we test the hypothesis that the source code of the entire Java class contains more information than just the commit diff and could potentially improve the performance of our model.\nRQ3: Does exploiting path-based representations of Java source code before and after the change improve the identification of security-relevant commits? For this research question, we test whether code2vec, a state-of-the-art model that learns from path-based representations of code, performs better than our model that treats source code as unstructured text.\nRQ4: Is mining commits using regular expression matching of commit messages an effective means of data augmentation for improving the identification of security-relevant commits? Since labelling commits manually is an expensive task, it is not easy to build a dataset large enough to train deep learning models. For this research question, we explore if collecting coarse data samples using a high-precision approach is an effective way to augment the ground-truth dataset.\nThe main contributions of this paper are:\n[leftmargin=*]\nNovel hierarchical deep learning models for the identification of security-relevant commits based on either the diff or the modified source code of the Java classes.\nA comparative analysis of how various deep learning models perform across different input representations and how various regularization techniques help with the generalization of our models.\nWe envision that this work would ultimately allow for monitoring open-source repositories in real-time, in order to automatically detect security-relevant changes such as vulnerability fixes.\nRQ2: Does extracting class-level features before and after the change instead of using only the commit diff improve the identification of security-relevant commits? For this research question, we test the hypothesis that the source code of the entire Java class contains more information than just the commit diff and could potentially improve the performance of our model.",

        "evidence": "The name Mumbai (Marathi: मुंबई, Gujarati: મુંબઈ, Hindi: मुंबई) derived from Mumbā or Mahā-Ambā—the name of the patron goddess (kuladevata) Mumbadevi of the native Koli community—and ā'ī meaning \"mother\" in the Marathi language, which is the mother tongue of the Koli people and the official language of Maharashtra. The Koli people originated in Kathiawar and Central Gujarat, and according to some sources they brought their goddess Mumba with them from Kathiawar (Gujarat), where she is still worshipped. However, other sources disagree that Mumbai's name was derived from the goddess Mumba.\n\n\n\nThe oldest known names for the city are Kakamuchee and Galajunkja; these are sometimes still used. In 1508, Portuguese writer Gaspar Correia used the name \"Bombaim\" in his Lendas da Índia (Legends of India). This name possibly originated as the Galician-Portuguese phrase bom baim, meaning \"good little bay\", and Bombaim is still commonly used in Portuguese. In 1516, Portuguese explorer Duarte Barbosa used the name Tana-Maiambu: Tana appears to refer to the adjoining town of Thane and Maiambu to Mumbadevi.\n\nOther variations recorded in the 16th and the 17th centuries include: Mombayn (1525), Bombay (1538), Bombain (1552), Bombaym (1552), Monbaym (1554), Mombaim (1563), Mombaym (1644), Bambaye (1666), Bombaiim (1666), Bombeye (1676), Boon Bay (1690), and Bon Bahia. After the English gained possession of the city in the 17th century, the Portuguese name was anglicised as Bombay. Ali Muhammad Khan, imperial dewan or revenue minister of the Gujarat province, in the Mirat-i Ahmedi (1762) referred to the city as Manbai.\n\nThe French traveller Louis Rousselet, who visited in 1863 and 1868, states in his book L'Inde des Rajahs, which was first published in 1877: \"Etymologists have wrongly derived this name from the Portuguese Bôa Bahia, or (French: \"bonne bai\", English: \"good bay\"), not knowing that the tutelar goddess of this island has been, from remote antiquity, Bomba, or Mumba Devi, and that she still ... possesses a temple\".\n\nBy the late 20th century, the city was referred to as Mumbai or Mambai in Marathi, Konkani, Gujarati, Kannada and Sindhi, and as Bambai in Hindi. The Government of India officially changed the English name to Mumbai in November 1995. This came at the insistence of the Marathi nationalist Shiv Sena party, which had just won the Maharashtra state elections, and mirrored similar name changes across the country and particularly in Maharashtra. According to Slate magazine, \"they argued that 'Bombay' was a corrupted English version of 'Mumbai' and an unwanted legacy of British colonial rule.\" Slate also said \"The push to rename Bombay was part of a larger movement to strengthen Marathi identity in the Maharashtra region.\" While Mumbai is still referred to as Bombay by some of its residents and by some Indians from other regions, mention of the city by a name other than Mumbai has been controversial.",

        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nIn this exploratory study, we present a speechto-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT.",

        "answer": "Yes, it does.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nCapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.",

        "evidence": "In order to find the object type, SimplerVoice, first, builds an ontology-based knowledge tree. Then, the system maps the object with a tree's leaf node based on the object's title. For instance, given the object's title as “Thomas' Plain Mini Bagels\", SimplerVoice automatically defines that the object category is “bagel\". Note that both the knowledge tree, and the mapping between object and object category are obtained based on text-based searching / crawling web, or through semantic webs' content. Figure FIGREF6 shows an example of the sub-tree for object category \"bagel\". While the mapped leaf node is the O in our S-V-O model, the parents nodes describe the more general object categories, and the neighbors indicate other objects' types which are similar to the input object. All the input object's type, the direct parents category, and the neighbors' are, then, put in the next step: generating verbs (V).\nWe propose to use 2 methods to generate the suitable verbs for the target object: heuristics-based, and n-grams model. In detail, SimplerVoice has a set of rule-based heuristics for the objects. For instance, if the object belongs to a \"food | drink\" category, the verb is generated as \"eat | drink\". Another example is the retrieved \"play\" verb if input object falls into \"toy\" category. However, due to the complexity of object's type, heuristics-based approach might not cover all the contexts of object. As to solve this, an n-grams model is applied to generate a set of verbs for the target object. An n-gram is a contiguous sequence of n items from a given speech, or text string. N-grams model has been extensively used for various tasks in text mining, and natural language processing field BIBREF14 , BIBREF15 . Here, we use the Google Books n-grams database BIBREF16 , BIBREF17 to generate a set of verbs corresponding to the input object's usage. Given a noun, n-grams model can provide a set of words that have the highest frequency of appearance followed by the noun in the database of Google Books. For an example, \"eaten\", \"toasted\", \"are\", etc. are the words which are usually used with \"bagel\". To get the right verb form, after retrieving the words from n-grams model, SimplerVoice performs word stemming BIBREF18 on the n-grams' output.\nIn order to find the object type, SimplerVoice, first, builds an ontology-based knowledge tree.\nWe propose to use 2 methods to generate the suitable verbs for the target object: heuristics-based, and n-grams model.",

They don't reflect the views of the authors in any way, and the point of the paper is to help fight such speech. Much recent interest has focused on the detection of offensive language and hate speech in online social media. Such language is often associated with undesirable online behaviors such as trolling, cyberbullying, online extremism, political polarization, and propaganda. Thus, offensive language detection is instrumental for a variety of application such as: quantifying polarization BIBREF0, BIBREF1, trolls and propaganda account detection BIBREF2, detecting the likelihood of hate crimes BIBREF3; and predicting conflict BIBREF4. In this paper, we describe our methodology for building a large dataset of Arabic offensive tweets. Given that roughly 1-2% of all Arabic tweets are offensive BIBREF5, targeted annotation is essential for efficiently building a large dataset. Since our methodology does not use a seed list of offensive words, it is not biased by topic, target, or dialect. Using our methodology, we tagged 10,000 Arabic tweet dataset for offensiveness, where offensive tweets account for roughly 19% of the tweets. Further, we labeled tweets as vulgar or hate speech. To date, this is the largest available dataset, which we plan to make publicly available along with annotation guidelines. We use this dataset to characterize Arabic offensive language to ascertain the topics, dialects, and users' gender that are most associated with the use of offensive language. Though we suspect that there are common features that span different languages and cultures, some characteristics of Arabic offensive language is language and culture specific. Thus, we conduct a thorough analysis of how Arabic users use offensive language. Next, we use the dataset to train strong Arabic offensive language classifiers using state-of-the-art representations and classification techniques.

BioIE systems aim to extract information from a wide spectrum of articles including medical literature, biological literature, electronic health records, etc. that can be used by clinicians and researchers in the field. Often the outputs of BioIE systems are used to assist in the creation of databases, or to suggest new paths for research. For example, a ranked list of interacting proteins that are extracted from biomedical literature, but are not present in existing databases, can allow researchers to make informed decisions about which protein/gene to study further.

        "answer": "How continuous speech separation can fit in with an overall meeting transcription architecture to generate speaker-annotated transcripts.",
        "evidence": "\nThe goal of meeting transcription is to have machines generate speaker-annotated transcripts of natural meetings based on their audio and optionally video recordings. Meeting transcription and analytics would be a key to enhancing productivity as well as improving accessibility in the workplace. It can also be used for conversation transcription in other domains such as healthcare BIBREF0. Research in this space was promoted in the 2000s by NIST Rich Transcription Evaluation series and public release of relevant corpora BIBREF1, BIBREF2, BIBREF3. While systems developed in the early days yielded high error rates, advances have been made in individual component technology fields, including conversational speech recognition BIBREF4, BIBREF5, far-field speech processing BIBREF6, BIBREF7, BIBREF8, and speaker identification and diarization BIBREF9, BIBREF10, BIBREF11. When cameras are used in addition to microphones to capture the meeting conversations, speaker identification quality could be further improved thanks to the computer vision technology. These trends motivated us to build an end-to-end audio-visual meeting transcription system to identify and address unsolved challenges. This report describes our learning, with focuses on overall architecture design, overlapped speech recognition, and audio-visual speaker diarization.\nWhen designing meeting transcription systems, different constraints must be taken into account depending on targeted scenarios. In some cases, microphone arrays are used as an input device. If the names of expected meeting attendees are known beforehand, the transcription system should be able to provide each utterance with the true identity (e.g., “Alice” or “Bob”) instead of a randomly generated label like “Speaker1”. It is often required to show the transcription in near real time, which makes the task more challenging.\nThis work assumes the following scenario. We consider a scheduled meeting setting, where an organizer arranges a meeting in advance and sends invitations to attendees. The transcription system has access to the invitees' names. However, actual attendees may not completely match those invited to the meeting. The users are supposed to enroll themselves in the system beforehand so that their utterances in the meeting can be associated with their names. The meeting is recorded with an audio-visual device equipped with a seven-element circular microphone array and a fisheye camera. Transcriptions must be shown with a latency of up to a few seconds.\nThis paper investigates three key challenges.\n\nSpeech overlaps: Recognizing overlapped speech has been one of the main challenges in meeting transcription with limited tangible progress. Numerous multi-channel speech separation methods were proposed based on independent component analysis or spatial clustering BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. However, there was little successful effort to apply these methods to natural meetings. Neural network-based single-channel separation methods using techniques like permutation invariant training (PIT) BIBREF18 or deep clustering (DC) BIBREF19 are known to be vulnerable to various types of acoustic distortion, including reverberation and background noise BIBREF20. In addition, these methods were tested almost exclusively on small-scale segmented synthetic data and have not been applied to continuous conversational speech audio. Although the recently held CHiME-5 challenge helped the community make a step forward to a realistic setting, it still allowed the use of ground-truth speaker segments BIBREF21, BIBREF22.\nWe address this long-standing problem with a continuous speech separation (CSS) approach, which we proposed in our latest conference papers BIBREF23, BIBREF24. It is based on an observation that the maximum number of simultaneously active speakers is usually limited even in a large meeting. According to BIBREF25, two or fewer speakers are active for more than 98% of the meeting time. Thus, given continuous multi-channel audio observation, we generate a fixed number, say $N$, of time-synchronous signals. Each utterance is separated from overlapping voices and background noise. Then, the separated utterance is spawned from one of the $N$ output channels. For periods where the number of active speakers is fewer than $N$, the extra channels generate zeros. We show how continuous speech separation can fit in with an overall meeting transcription architecture to generate speaker-annotated transcripts.\nNote that our speech separation system does not make use of a camera signal. While much progress has been made in audio-visual speech separation, the challenge of dealing with all kinds of image variations remains unsolved BIBREF26, BIBREF27, BIBREF28.\n\nExtensible framework: It is desirable that a single transcription system be able to support various application settings for both maintenance and scalability purposes. While this report focuses on the audio-visual setting, our broader work covers an audio-only setting as well as the scenario where no prior knowledge of meeting attendees is available. A modular and versatile architecture is desired to encompass these different settings.\nTo this end, we propose a framework called SRD, which stands for “separate, recognize, and diarize”, where CSS, speech recognition, and speaker diarization takes place in tandem. Performing CSS at the beginning allows the other modules to operate on overlap-free signals. Diarization is carried out after speech recognition because its implementation can vary significantly depending on the application settings. By choosing an appropriate diarization module for each setting, multiple use cases can be supported without changing the rest of the system. This architecture also allows transcriptions to be displayed in real time without speaker information. Speaker identities for each utterance may be shown after a couple of seconds.\n\nAudio-visual speaker diarization: Speaker diarization, a process of segmenting input audio and assigning speaker labels to the individual segments, can benefit from a camera signal. The phenomenal improvements that have been made to face detection and identification algorithms by convolutional neural networks (CNNs) BIBREF29, BIBREF30, BIBREF31 make the camera signal very appealing for speaker diarization. While much prior work assumes the batch processing scenario where the entire meeting recording can be processed multiple times, several studies deal with online processing BIBREF32, BIBREF33, BIBREF34, BIBREF35. However, no previous studies comprehensively address the challenges that one might encounter in real meetings. BIBREF32, BIBREF33 do not cope with speech overlaps. While the methods proposed in BIBREF34, BIBREF35 address the overlap issue, they rely solely on spatial cues and thus are not applicable when multiple speakers sit side by side.\nOur diarization method handles overlapping utterances as well as co-located speakers by utilizing the time-frequency (TF) masks generated by CSS in speaker identification and sound source localization (SSL). In addition, several enhancements are made to face identification to improve robustness to image variations caused by face occlusions, extreme head pose, lighting conditions, and so on.\nWe show how continuous speech separation can fit in with an overall meeting transcription architecture to generate speaker-annotated transcripts.",

        "evidence": "Consider the task of translating from an extremely low-resource language (source) to a target language. The parallel corpus between the two languages if available may be too small to train a NMT model. Similar to existing works BIBREF3 , BIBREF10 , BIBREF12 , we use transfer learning to overcome data sparsity and train a NMT model between the source and the target languages. Specifically, the NMT model (parent model) is trained on the assisting language and target language pairs. We choose English as the assisting language in all our experiments. In our resource-scarce scenario, we have no parallel corpus for the child task. Hence, at test time, the source language sentence is translated using the parent model after performing a word-by-word translation into the assisting language.\nSince the source language and the assisting language (English) have different word order, we hypothesize that it leads to inconsistencies in the contextual representations generated by the encoder for the two languages. In this paper, we propose to pre-order English sentences (assisting language sentences) to match the word-order of the source language and train the parent model on this pre-ordered corpus. In our experiments, we look at scenarios where the assisting language has SVO word order and the source language has SOV word order.\nFor instance, consider the English sentence Anurag will meet Thakur. One of the pre-ordering rule swaps the position of the noun phrase followed by a transitive verb with the transitive verb. The original and the resulting re-ordered parse tree will be as shown in the Table TABREF5 . Applying this reordering rule to the above sentence Anurag will meet Thakur will yield the reordered sentence Anurag Thakur will meet. Additionally, the Table TABREF5 shows the parse trees for the above sentence with and without pre-ordering.\nPre-ordering should also be beneficial for other word order divergence scenarios (e.g., SOV to SVO), but we leave verification of these additional scenarios for future work.\nConsider the task of translating for an extremely low-resource language pair.

        "evidence": "The exploding multimedia content over the Internet, has created a new world of spoken content processing, for example the retrieval BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , browsing BIBREF5 , summarization BIBREF0 , BIBREF5 , BIBREF6 , BIBREF7 , and comprehension BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 of spoken content. On the other hand, we may realize there still exists a huge part of multimedia content not yet taken care of, i.e., the singing content or those with audio including songs. Songs are human voice carrying plenty of semantic information just as speech. It will be highly desired if the huge quantities of singing content can be similarly retrieved, browsed, summarized or comprehended by machine based on the lyrics just as speech. For example, it is highly desired if song retrieval can be achieved based on the lyrics in addition.\nSinging voice can be considered as a special type of speech with highly flexible and artistically designed prosody: the rhythm as artistically designed duration, pause and energy patterns, the melody as artistically designed pitch contours with much wider range, the lyrics as artistically authored sentences to be uttered by the singer. So transcribing lyrics from song audio is an extended version of automatic speech recognition (ASR) taking into account these differences.\nOn the other hand, singing voice and speech differ widely in both acoustic and linguistic characteristics. Singing signals are often accompanied with some extra music and harmony, which are noisy for recognition. The highly flexible pitch contours with much wider range BIBREF12 , BIBREF13 , the significantly changing phone durations in songs, including the prolonged vowels BIBREF14 , BIBREF15 over smoothly varying pitch contours, create much more problems not existing in speech. The falsetto in singing voice may be an extra type of human voice not present in normal speech. Regarding linguistic characteristics BIBREF16 , BIBREF17 , word repetition and meaningless words (e.g.oh) frequently appear in the artistically authored lyrics in singing voice.\nApplying ASR technologies to singing voice has been studied for long. However, not too much work has been reported, probably because the recognition accuracy remained to be relatively low compared to the experiences for speech. But such low accuracy is actually natural considering the various difficulties caused by the significant differences between singing voice and speech. An extra major problem is probably the lack of singing voice database, which pushed the researchers to collect their own closed datasets BIBREF12 , BIBREF15 , BIBREF17 , which made it difficult to compare results from different works.\nHaving the language model learned from a data set of lyrics is definitely helpful BIBREF15 , BIBREF17 . Hosoya et al. BIBREF16 achieved this with finite state automaton. Sasou et al. BIBREF12 actually prepared a language model for each song. In order to cope with the acoustic characteristics of singing voice, Sasou et al. BIBREF12 , BIBREF14 proposed AR-HMM to take care of the high-pitched sounds and prolonged vowels, while recently Kawai et al. BIBREF15 handled the prolonged vowels by extending the vowel parts in the lexicon, both achieving good improvement. Adaptation from models trained with speech was attractive, and various approaches were compared by Mesaros el al. BIBREF18 .\nIn this paper, we wish our work can be compatible to more available singing content, therefore in the initial effort we collected about five hours of music-removed version of English songs directly from commercial singing content on YouTube. The descriptive term \"music-removed\" implies the background music have been removed somehow. Because many very impressive works were based on Japanese songs BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , the comparison is difficult. We analyzed various approaches with HMM, deep learning with data augmentation, and acoustic adaptation on fragment, song, singer, and genre levels, primarily based on fMLLR BIBREF19 . We also trained the language model with a corpus of lyrics, and modify the pronunciation lexicon and increase the transition probability of HMM for prolonged vowels.

Going one step further, emotion cause extraction can reveal important information about what causes a certain emotion and why there is an emotion change. In this section, we introduce related work on emotion analysis including emotion cause extraction.\nIn emotion analysis, we first need to determine the taxonomy of emotions. Researchers have proposed a list of primary emotions BIBREF7 , BIBREF8 , BIBREF9 . In this study, we adopt Ekman's emotion classification scheme BIBREF8 , which identifies six primary emotions, namely happiness, sadness, fear, anger, disgust and surprise, as known as the “Big6” scheme in the W3C Emotion Markup Language. This emotion classification scheme is agreed upon by most previous works in Chinese emotion analysis.\nExisting work in emotion analysis mostly focuses on emotion classification BIBREF10 , BIBREF11 and emotion information extraction BIBREF12 . xu2012coarse used a coarse to fine method to classify emotions in Chinese blogs. gao2013joint proposed a joint model to co-train a polarity classifier and an emotion classifier. beck2014joint proposed a Multi-task Gaussian-process based method for emotion classification. chang2015linguistic used linguistic templates to predict reader's emotions. das2010finding used an unsupervised method to extract emotion feelers from Bengali blogs.

Based on this corpus, chen2010emotion proposed a rule based method to detect emotion causes based on manually define linguistic rules. Some studies BIBREF23 , BIBREF24 , BIBREF25 extended the rule based method to informal text in Weibo text (Chinese tweets).\nOther than rule based methods, russo2011emocause proposed a crowdsourcing method to construct a common-sense knowledge base which is related to emotion causes. But it is challenging to extend the common-sense knowledge base automatically. ghazi2015detecting used Conditional Random Fields (CRFs) to extract emotion causes.

More recently, gui2016event proposed a multi-kernel based method to extract emotion causes through learning from a manually annotated emotion cause dataset.\n[id=lq]Most existing work does not consider the relation between an emotion word and the cause of such an emotion, or they simply use the emotion word as a feature in their model learning. Since emotion cause extraction requires an understanding of a given piece of text in order to correctly identify the relation between the description of an event which causes an emotion and the expression of that emotion, it can essentially be considered as a QA task. In our work, we choose the memory network, which is designed to model the relation between a story and a query for QA systems BIBREF26 , BIBREF27 . Apart from its application in QA, memory network has also achieved great successes in other NLP tasks, such as machine translation BIBREF28 , sentiment analysis BIBREF29 or summarization BIBREF30 . To the best of our knowledge, this is the first work which uses memory network for emotion cause extraction.\nIn this study, we adopt Ekman’s emotion classification scheme (Ekman, 1984), which identifies six primary emotions, namely happiness, sadness, fear, anger, disgust and surprise, known as the “Big6” scheme in the W3C Emotion Markup Language.",

We define the amodal depth for a pixel ray to be delineated by the minimum between the closest structure-category surface (e.g. walls and doors, etc) and the farthest surface. In practice, in order to accommodate the evaluation of the surfaces right on the amodal depth, we slack the evaluation scope with a factor λ (1.05 in our case) multiplied with the amodal depth. This evaluation protocol would be equivalent to the “single-layered” protocol used in Sun et al. (2021), within our single-view scenario. Due to the inherent ambiguity of the scaling and shifting of the predicted 3D single view geometry (Ranftl et al., 2019; Yin et al., 2021), we follow them by regressing the best scale and shift comparing the predicted depth with the ground truth depth. For approaches that predict 3D surfaces, the rendered depth map from the predicted mesh would be used for calculating the scale and shift.",

You don’t need to predict who is going to respond and who is not going to respond. In this case, you need to rank order your customers with most probability of response to least probability of response and give your manager the top 20 or 30%. So in this case, y or the dependent variable is just the logit score or the ranking estimates. However, if the idea is to predict the decisions (i.e. classification of the predicted rankings into decisions) then we need the logistic regression model to calculate the prediction estimates based on the logistic function which uses the logit score. Then using an appropriate threshold value, these prediction estimates can be converted to decisions.",

Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.\nThe presence of either a positive or negative electric charge produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. In most applications, a force acts on a charge with a magnitude given by Coulomb's law. Electric potential is typically measured in volts.\nElectricity is at the heart of many modern technologies, being used for:\nElectric power where electric current is used to energise equipment;\nElectronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.\nElectrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the 17th and 18th centuries. The theory of electromagnetism was developed in the 19th century, and by the end of that century electricity was being put to industrial and residential use by electrical engineers. The rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution.

        "evidence": "Problem Definition We are given a dataset $(S,Y) = \\lbrace (\\mathbb {S}_1,y_1),(\\mathbb {S}_2,y_2)\\dots (\\mathbb {S}_m,y_m)\\rbrace $ and a trained classification model $C:\\mathbb {S}\\rightarrow Y$. We assume the soft-label black-box setting where the attacker can only query the classifier for output probabilities on a given input, and does not have access to the model parameters, gradients or training data. For an input pair $(\\mathbb {S},y)$, we want to generate an adversarial example $\\mathbb {S}_{adv}$ such that $C(\\mathbb {S}_{adv}){\\ne }y$ where $\\mathbb {S}_{adv}$ is natural looking, grammatically correct and semantically similar to $\\mathbb {S}$ (by some pre-defined definition\nof similarity).\nBAE For generating adversarial example $\\mathbb {S}_{adv}$, we define two perturbations on the input $\\mathbb {S}$:\nReplace a token $t \\in \\mathbb {S}$ with another\nInsert a new token $t^{\\prime }$ in $\\mathbb {S}$\nSome tokens in the input are more attended to by $C$ than others, and therefore contribute more towards the final prediction. Replacing these tokens or inserting a new token adjacent to them can thus have a stronger effect on altering the classifier prediction. We estimate the token importance $I_i$ of each token $t_i \\in \\mathbb {S}=[t_1, \\dots , t_n]$, by deleting $t_i$ from $\\mathbb {S}$ and computing the decrease in probability of predicting the correct label $y$, similar to BIBREF11.\nWhile the motivation for replacing tokens in decreasing order of importance is clear, we conjecture that adjacent insertions in this same order can lead to a powerful attack. This intuition stems from the fact that the inserted token changes the local context around the original token.\nThe Replace (R) and Insert (I) operations are performed on a token $t$ by masking it and inserting a mask token adjacent to it in $\\mathbb {S}$ respectively. The pre-trained BERT masked language model (MLM) is used to predict the mask tokens (See Figure FIGREF1).\nBERT is a powerful LM trained on a large training corpus ($\\sim $ 2 billion words), and hence the predicted mask tokens fit well grammatically in $\\mathbb {S}$. The BERT-MLM does not however guarantee semantic coherence to the original text $\\mathbb {S}$ as demonstrated by the following simple example. Consider the sentence: `the food was good'. For replacing the token `good', BERT-MLM may predict the tokens `nice' and `bad', both of which fit well into the context of the sentence. However, replacing `good' with `bad' changes the original sentiment of the sentence.\nTo ensure semantic similarity on introducing perturbations in the input text, we filter the set of top K masked tokens (K is a pre-defined constant) predicted by BERT-MLM using a Universal Sentence Encoder (USE) BIBREF14 based sentence similarity scorer. For the R operations we add an additional check for grammatical correctness of the generated adversarial example by filtering out predicted tokens that do not form the same part of speech (POS) as the original token $t_i$ in the sentence.\nTo choose the token for a perturbation (R/I) that best attacks the model from the filtered set of predicted tokens:\nIf there are multiple tokens can cause $C$ to misclassify $\\mathbb {S}$ when they replace the mask, we choose the token which makes $\\mathbb {S}_{adv}$ most similar to the original $\\mathbb {S}$ based on the USE score.\nIf no token causes misclassification, we choose the perturbation that decreases the prediction probability $P(C(\\mathbb {S}_{adv}){=}y)$ the most.\nThe perturbations are applied iteratively to the input tokens in decreasing order of importance, until either $C(\\mathbb {S}_{adv}){\\ne }y$ (successful attack) or all the tokens of $\\mathbb {S}$ have been perturbed (failed attack).\nWe present 4 attack modes for BAE based on the R and I operations, where for each token $t$ in $\\mathbb {S}$:\nBAE-R: Replace token $t$ (See Algorithm )\nBAE-I: Insert a token to the left or right of $t$\nBAE-R/I: Either replace token $t$ or insert a token to the left or right of $t$\nBAE-R+I: First replace token $t$, then insert a token to the left or right of $t$\nTo achieve a high semantic similarity with the original text on introducing perturbations, we filter the set of top K tokens (K is a pre-defined constant) predicted by BERT-MLM for the masked token, using a Universal Sentence En- coder (USE) based sentence similarity scorer (Cer et al., 2018).",

Originally, colonial Americans mostly lived outside of towns, farming and hunting in the countryside. This meant that guns were not just for protection, they were for obtaining crucial food resources. The British threat to take away guns was more than a political imposition limiting resistance to British rule, it was potentially a life-threatening policy to families who depended on obtaining food via hunting. This background is in part why Americans originally had such a strong reaction to normalizing gun controls and access, which was codified as a right to bear arms in our Constitution. However, by contrast this aspect of the rationale against gun control largely does not exist today. Gun usage is for sport, and for protection, and only minimally to provide food on the table. However, because of this history, and constitutional codification, Americans feel justified in maintaining one of the world's most vigorous objections to any regulation or controls.",

Further details can be found at BIBREF23.\nObjective of the study was to design an ML based system for extracting open domain calendar of significant events from Twitter-data. 38 different types of events were considered for designing the system. To train the ML model, an annotated corpus of 1000 tweets (containing 19,484 tokens) was used and trained model was tested on 100 million most recent tweets. Further details can be found at BIBREF24.\nTable TABREF21 below depicts classes of features selected by authors of these works (as described in the corresponding references above) to highlight the point that despite domain differences, these applications share similar sets of features. Since authors of these works did not cite each other, it is possible that that these features might have been identified independently. This, in turn, supports the hypothesis that if adequate details of any one or two of these applications are fed to a system described in this work, which is designed to estimate semantic similarities across applications, system can automatically suggest potential features for consideration for the remaining applications to start with without requiring manual knowledge of the semantically related applications.\nObjective of the study was to design an ML based system for extracting open domain calendar of significant events from Twitter-data.",

        "question": "Given these paragraphs about Asperger syndrome, what disorder has it merged into?",
        "evidence": "Asperger syndrome (AS), also known as Asperger's, is a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behaviour and interests. The syndrome is no longer recognised as a diagnosis in itself, having been merged with other conditions into autism spectrum disorder (ASD). It was considered to differ from other diagnoses that were merged into ASD by relatively unimpaired spoken language and intelligence.\n\nThe syndrome was named after the Austrian pediatrician Hans Asperger, who, in 1944, described children in his care who struggled to form friendships, did not understand others' gestures or feelings, engaged in one-sided conversations about their favourite interests, and were clumsy. In 1994, the diagnosis of Asperger's was included in the fourth edition (DSM-IV) of the American Diagnostic and Statistical Manual of Mental Disorders; however, with the publication of DSM-5 in 2013 the syndrome was removed, and the symptoms are now included within autism spectrum disorder along with classic autism and pervasive developmental disorder not otherwise specified (PDD-NOS). It was similarly merged into autism spectrum disorder in the International Classification of Diseases (ICD-11) as of 2021.\n\nThe exact cause of Asperger's is poorly understood. While it has high heritability, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role. Brain imaging has not identified a common underlying condition. There is no single treatment, and the UK's National Health Service (NHS) guidelines suggest that 'treatment' of any form of autism should not be a goal, since autism is not 'a disease that can be removed or cured'. According to the Royal College of Psychiatrists, while co-occurring conditions might require treatment, 'management of autism itself is chiefly about the provision of the education, training and social support/care required to improve the person's ability to function in the everyday world'. The effectiveness of particular interventions for autism is supported by only limited data. Interventions may include social skills training, cognitive behavioral therapy, physical therapy, speech therapy, parent training, and medications for associated problems, such as mood or anxiety. Autistic characteristics tend to become less obvious in adulthood, but social and communication difficulties usually persist.\n\nhttps://en.wikipedia.org/wiki/Asperger_syndrome",

        "answer": "Over 16k chat dialogues with manually annotated summaries.",
        "evidence": "The goal of the summarization task is condensing a piece of text into a shorter version that covers the main points succinctly. In the abstractive approach important pieces of information are presented using words and phrases not necessarily appearing in the source text. This requires natural language generation techniques with high level of semantic understanding BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6.\nMajor research efforts have focused so far on summarization of single-speaker documents like news (e.g., BIBREF7) or scientific publications (e.g., BIBREF8). One of the reasons is the availability of large, high-quality news datasets with annotated summaries, e.g., CNN/Daily Mail BIBREF9, BIBREF7. Such a comprehensive dataset for dialogues is lacking.\nThe challenges posed by the abstractive dialogue summarization task have been discussed in the literature with regard to AMI meeting corpus BIBREF10, e.g. BIBREF11, BIBREF12, BIBREF13. Since the corpus has a low number of summaries (for 141 dialogues), BIBREF13 proposed to use assigned topic descriptions as gold references. These are short, label-like goals of the meeting, e.g., costing evaluation of project process; components, materials and energy sources; chitchat. Such descriptions, however, are very general, lacking the messenger-like structure and any information about the speakers.\nTo benefit from large news corpora, BIBREF14 built a dialogue summarization model that first converts a conversation into a structured text document and later applies an attention-based pointer network to create an abstractive summary. Their model, trained on structured text documents of CNN/Daily Mail dataset, was evaluated on the Argumentative Dialogue Summary Corpus BIBREF15, which, however, contains only 45 dialogues.\nIn the present paper, we further investigate the problem of abstractive dialogue summarization. With the growing popularity of online conversations via applications like Messenger, WhatsApp and WeChat, summarization of chats between a few participants is a new interesting direction of summarization research. For this purpose we have created the SAMSum Corpus which contains over 16k chat dialogues with manually annotated summaries. The dataset is freely available for the research community.\nThe paper is structured as follows: in Section SECREF2 we present details about the new corpus and describe how it was created, validated and cleaned.

        "evidence": "",
        "answer": "Not all planets and moons are round. There is some variety in their shapes depending on their masses, and curiously looking worlds might even exist, unlike anything we know from our system.\n\nEverything within a planet or a moon is under the influence of gravity in such a way that bits of it would move to the center if they could. Under ideal conditions, it would acquire a spherical shape. For objects made of something other than liquids, it varies at what point they become round. It is generally assumed that they mostly become spheres around 400 kilometers/248 miles in diameter when made from icy material commonly found in our Solar System. Still, if something is made from something more rigid, it needs to be larger in diameter than that - around 750 km/466 miles. At a sufficient mass, even rock becomes fluid-like. The moon of Mars Deimos is only 12.6 km/7.8 miles across and is not spherical, and there are many other small moons of other planets that don’t have a round shape.\n\nThis, however, is not all. Astronomical objects spin, giving them the flattened shape of a sphere the faster their rotation if they are massive enough. On top of it, they can have moons. This causes a bulge to form at the position of their orbiting body around them. In the case of Earth, our Moon causes tides via this process. Also, our Sun gives our planet tides. Elsewhere in the Universe, there could be planets with massive moons or two similarly massive planets, called double planets, orbiting their common center of mass, the barycenter, at a close distance, which can cause even stronger bulging. Their shape would be affected this way more visibly.\n\nFinally, a bizarre, toroidal planet, shown above, can be stable from what we know from physics, at least for a while. As I mentioned earlier, even rigid rock behaves like a fluid at large masses. An adequate rotation speed can counterbalance the strength of gravity with centrifugal acceleration, and a torus-shaped planet could exist. A possible scenario for such a world to come to be would be if two sufficiently fast rotating planets collided and formed a doughnut of vaporized rock, a so-called synestia.\n\nWe currently think that the events that would lead to the formation of a world of this shape are so unlikely that there might not be a single toroidal planet in the Visible Universe, but we were quite a few times surprised by what we discovered during our exploration of Cosmos. Perhaps we will even find a doughnut shape world one day.",

Three annotators, who have no knowledge about which system the response is from, are then required to evaluate among win (response$_1$ is better), loss (response$_2$ is better) and tie (they are equally good or bad) independently, considering four aspects: coherence, logical consistency, fluency and diversity. Cases with different rating results are counted as “tie”. Table TABREF25 reveals the results of the subjective evaluation. We observe that our multi-curricula learning framework outperforms the vanilla training method on all the five dialogue models and the kappa scores indicate that the annotators came to a fair agreement in the judgment.

        "evidence": "For the projection we can use an arbitrary invertible function, and given the representational power of neural networks they seem a natural choice. However, calculating the inverse and Jacobian of an arbitrary neural network can be difficult, as it requires that all component functions be invertible and also requires storage of large Jacobian matrices, which is memory intensive. To address this issue, several recent papers propose specially designed invertible networks that are easily trainable yet still powerful BIBREF16 , BIBREF17 , BIBREF19 . Inspired by these works, we use the invertible transformation proposed by BIBREF16 , which consists of a series of “coupling layers”. This architecture is specially designed to guarantee a unit Jacobian determinant (and thus the invertibility property).\nFrom Eq. ( EQREF22 ) we know that only INLINEFORM0 is required for accomplishing learning and inference; we never need to explicitly construct INLINEFORM1 . Thus, we directly define the architecture of INLINEFORM2 . As shown in Figure FIGREF24 , the nonlinear transformation from the observed embedding INLINEFORM3 to INLINEFORM4 represents the first coupling layer. The input in this layer is partitioned into left and right halves of dimensions, INLINEFORM5 and INLINEFORM6 , respectively. A single coupling layer is defined as: DISPLAYFORM0 \nwhere INLINEFORM0 is the coupling function and can be any nonlinear form. This transformation satisfies INLINEFORM1 , and BIBREF16 show that its Jacobian matrix is triangular with all ones on the main diagonal. Thus the Jacobian determinant is always equal to one (i.e. volume-preserving) and the invertibility condition is naturally satisfied.\nTo be sufficiently expressive, we compose multiple coupling layers as suggested in BIBREF16 . Specifically, we exchange the role of left and right half vectors at each layer as shown in Figure FIGREF24 . For instance, from INLINEFORM0 to INLINEFORM1 the left subset INLINEFORM2 is unchanged, while from INLINEFORM3 to INLINEFORM4 the right subset INLINEFORM5 remains the same. Also note that composing multiple coupling layers does not change the volume-preserving and invertibility properties. Such a sequence of invertible transformations from the data space INLINEFORM6 to INLINEFORM7 is also called normalizing flow BIBREF20 .\nHowever, calculating the inverse and Jacobian of an arbitrary neural network can be difficult, as it requires that all component functions be invertible and also requires storage of large Jacobian matrices, which is memory intensive.",

        "evidence": "Since its rise in 2013, the Islamic State of Iraq and Syria (ISIS) has utilized the Internet to spread its ideology, radicalize individuals, and recruit them to their cause. In comparison to other Islamic extremist groups, ISIS' use of technology was more sophisticated, voluminous, and targeted. For example, during ISIS' advance toward Mosul, ISIS related accounts tweeted some 40,000 tweets in one day BIBREF0.However, this heavy engagement forced social media platforms to institute policies to prevent unchecked dissemination of terrorist propaganda to their users, forcing ISIS to adapt to other means to reach their target audience.\nOne such approach was the publication of online magazines in different languages including English. Although discontinued now, these online resources provided a window into ISIS ideology, recruitment, and how they wanted the world to perceive them. For example, after predominantly recruiting men, ISIS began to also include articles in their magazines that specifically addressed women. ISIS encouraged women to join the group by either traveling to the caliphate or by carrying out domestic attacks on behalf of ISIS in their respective countries. This tactical change concerned both practitioners and researchers in the counterterrorism community. New advancements in data science can shed light on exactly how the targeting of women in extremist propaganda works and whether it differs significantly from mainstream religious rhetoric.\nWe utilize natural language processing methods to answer three questions:\nWhat are the main topics in women-related articles in ISIS' online magazines?\nWhat similarities and/or differences do these topics have with non-violent, non-Islamic religious material addressed specifically to women?\nWhat kind of emotions do these articles evoke in their readers and are there similarities in the emotions evoked from both ISIS and non-violent religious materials?\nAs these questions suggest, to understand what, if anything, makes extremist appeals distinctive, we need a point of comparison in terms of the outreach efforts to women from a mainstream, non-violent religious group. For this purpose, we rely on an online Catholic women's forum. Comparison between Catholic material and the content of ISIS' online magazines allows for novel insight into the distinctiveness of extremist rhetoric when targeted towards the female population. To accomplish this task, we employ topic modeling and an unsupervised emotion detection method.\nThe rest of the paper is organized as follows: in Section SECREF2, we review related works on ISIS propaganda and applications of natural language methods. Section SECREF3 describes data collection and pre-processing. Section SECREF4 describes in detail the approach.

Males are more often affected with hepatocellular carcinoma (HCC) than females. Diagnosis is most frequent among those 55 to 65 years old.\n\nThe leading cause of liver cancer is cirrhosis due to hepatitis B, hepatitis C or alcohol. Other causes include aflatoxin, non-alcoholic fatty liver disease and liver flukes. The most common types are HCC, which makes up 80% of cases and intrahepatic cholangiocarcinoma. The diagnosis may be supported by blood tests and medical imaging, with confirmation by tissue biopsy.\n\nGiven that there are many different causes of liver cancer, there are many approaches to liver cancer prevention. These efforts include immunization against hepatitis B, hepatitis B treatment, hepatitis C treatment, decreasing alcohol use, decreasing exposure to aflatoxin in agriculture, and management of obesity and diabetes. Screening is recommended in those with chronic liver disease. For example, it is recommended that people with chronic liver disease who are at risk for hepatocellular carcinoma be screened every 6 months using ultrasound imaging.\n\nBecause liver cancer is an umbrella term for many types of cancer, the signs and symptoms depend on what type of cancer is present.

More specifically, the impetus of forming the organization came from a new law enacted by the colonial British rule which banned the barbaric practice of burning widows alive (sati) in the country; the focus of the new association was to repel the law which was seen as an intrusion by the British into the religious affairs of the indigenous people by some sections of the Hindu community. The Dharma Sabha filed an appeal in the Privy Council against the ban on Sati by Lord William Bentinck as, according to them, it went against the assurance given by George III of non-interference in Hindu religious affairs; however, their appeal was rejected and the ban on Sati was upheld in 1832.

Text features can be used in deep networks to capture text semantics or sentiment. For example, Dong et al. use an adaptive layer in a recursive neural network for target-dependent Twitter sentiment analysis, where targets are topics such as windows 7 or taylor swift BIBREF16 , BIBREF17 ; recursive neural tensor networks (RNTNs) utilize sentence parse trees to capture sentence-level sentiment for movie reviews BIBREF4 ; Le and Mikolov predict sentiment by using paragraph vectors to model each paragraph as a continuous representation BIBREF18 . They show that performance can thus be improved by more delicate text models.\nOthers have suggested using extra-linguistic features to improve the deep learning model. The user-word composition vector model (UWCVM) BIBREF19 is inspired by the possibility that the strength of sentiment words is user-specific; to capture this they add user embeddings in their model. In UPNN, a later extension, they further add a product-word composition as product embeddings, arguing that products can also show different tendencies of being rated or reviewed BIBREF20 . Their addition of user information yielded 2–10% improvements in accuracy as compared to the above-mentioned RNTN and paragraph vector methods. We also seek to inject user information into the neural network model. In comparison to the research of Tang et al. on sentiment classification for product reviews, the difference is two-fold. First, we take into account multiple users (one author and potentially many likers) for one post, whereas only one user (the reviewer) is involved in a review. Second, we add comment information to provide more features for post stance classification. None of these two factors have been considered previously in a deep learning model for text stance classification. Therefore, we propose UTCNN, which generates and utilizes user embeddings for all users — even for those who have not authored any posts — and incorporates comments to further improve performance.\nIn comparison to the research of Tang et al. on sentiment classification for product reviews, the difference is two-fold.

For Events, these values are provided by the training data, for Timex3s we have to compute class labels. Around 42% of Timex3 mentions are simple dates (“12/29/08\", “October 16\", etc.) and can be naively canonicalized to a universal timestamp. This is done using regular expressions to identify common date patterns and heuristics to deal with incomplete dates. The missing year in “October 16\", for example, can be filled in using the nearest preceding date mention; if that isn't available we use the document creation year. These mentions are then assigned a class using the parent document's DocTime value and any revision timestamps. Other Timex3 mentions are more ambiguous so we use a distant supervision approach. Phrases like “currently\" and “today's\" tend to occur near Events that overlap the current document creation time, while “ago\" or “ INLINEFORM0 -years\" indicate past events. These dominant temporal associations can be learned from training data and then used to label Timex3s.

        "evidence": "The goal of the current research was to investigate the automatic detection of cyberbullying-related posts on social media. Given the information overload on the web, manual monitoring for cyberbullying has become unfeasible. Automatic detection of signals of cyberbullying would enhance moderation and allow to respond quickly when necessary.\nCyberbullying research has often focused on detecting cyberbullying `attacks', hence overlooking posts written by victims and bystanders. However, these posts could just as well indicate that cyberbullying is going on. The main contribution of this paper is that it presents a system for detecting signals of cyberbullying on social media, including posts from bullies, victims and bystanders. A manually annotated cyberbullying dataset was created for two languages, which will be made available for public scientific use. Moreover, while a fair amount of research has been done on cyberbullying detection for English, we believe this is one of the first papers that focus on Dutch as well.\nA set of binary classification experiments were conducted to explore the feasibility of automatic cyberbullying detection on social media. In addition, we sought to determine which information sources contribute to this task. Two classifiers were trained on English and Dutch ASKfm data and evaluated on a holdout test of the same genre. Our experiments reveal that the current approach is a promising strategy for detecting signals of cyberbullying in social media data automatically. After feature selection and hyperparameter optimisation, the classifiers achieved an F INLINEFORM0 -score of 64.32% and 58.72% for English and Dutch, respectively. The systems hereby significantly outperformed a keyword and an (unoptimised) INLINEFORM1 -gram baseline. Analysis of the results revealed that false positives often include implicit cyberbullying or offenses through irony, the challenge of which will constitute an important area for future work.\nAnother interesting direction for future work would be the detection of fine-grained cyberbullying-related categories such as threats, curses and expressions of racism and hate. When applied in a cascaded model, the system could find severe cases of cyberbullying with high precision. This would be particularly interesting for monitoring purposes, since it would allow to prioritise signals of bullying that are in urgent need for manual inspection and follow-up.\nFinally, future work will focus on the detection of participants (or roles) typically involved in cyberbullying. This would allow to analyse the context of a cyberbullying incident and hence evaluate its severity. When applied as moderation support on online platforms, such a system would allow to provide feedback in function of the recipient (i.e., a bully, victim, or bystander).\nAnalysis of the combined and single feature type sets reveals that word n-grams, character n-grams, and subjectivity exicons prove to be strong features for this task.",

        "evidence": "Natural Language Processing (NLP) systems rely on large-scale training data BIBREF0 for supervised training. However, manual annotation can be time-consuming and expensive. Despite detailed annotation standards and rules, inter-annotator disagreement is inevitable because of human mistakes, language phenomena which are not covered by the annotation rules and the ambiguity of language itself BIBREF1 .\nExisting annotation tools BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 mainly focus on providing a visual interface for user annotation process but rarely consider the post-annotation quality analysis, which is necessary due to the inter-annotator disagreement. In addition to the annotation quality, efficiency is also critical in large-scale annotation task, while being relatively less addressed in existing annotation tools BIBREF6 , BIBREF7 . Besides, many tools BIBREF6 , BIBREF4 require a complex system configuration on either local device or server, which is not friendly to new users.\nTo address the challenges above, we propose Yedda , a lightweight and efficient annotation tool for text span annotation. A snapshot is shown in Figure FIGREF4 . Here text span boundaries are selected and assigned with a label, which can be useful for Named Entity Recognition (NER) BIBREF8 , word segmentation BIBREF9 , chunking BIBREF10 ,etc. To keep annotation efficient and accurate, Yedda provides systematic solutions across the whole annotation process, which includes the shortcut annotation, batch annotation with a command line, intelligent recommendation, format exporting and administrator evaluation/analysis.\nFigure FIGREF1 shows the general framework of Yedda. It offers annotators with a simple and efficient Graphical User Interface (GUI) to annotate raw text. For the administrator, it provides two useful toolkits to evaluate multi-annotated text and generate detailed comparison report for annotator pair. Yedda has the advantages of being:\n• INLINEFORM0 Convenient: it is lightweight with an intuitive interface and does not rely on specific operating systems or pre-installed packages.\n• INLINEFORM0 Efficient: it supports both shortcut and command line annotation models to accelerate the annotating process.\n• INLINEFORM0 Intelligent: it offers user with real-time system suggestions to avoid duplicated annotation.\n• INLINEFORM0 Comprehensive: it integrates useful toolkits to give the statistical index of analyzing multi-user annotation results and generate detailed content comparison for annotation pairs.\nThis paper is organized as follows: Section 2 gives an overview of previous text annotation tools and the comparison with ours. Section 3 describes the architecture of Yedda and its detail functions. Section 4 shows the efficiency comparison results of different annotation tools. Finally, Section 5 concludes this paper and give the future plans.\nTo keep annotation efficient and accurate, YEDDA provides systematic solutions across the whole annotation process, which includes the shortcut annotation, batch annotation with a command line, intelligent recommendation, format exporting and administrator evaluation/analysis.",

For example, dates, departure cities and destinations represent slots to fill in a flight booking task. This information is extracted from natural language queries leveraging typical context associated with each slot type. Researchers have been exploring data-driven approaches to learning models for automatic identification of slot information since the 90's, and significant advances have been made BIBREF0 . Our paper builds on recent work on slot-filling using recurrent neural networks (RNNs) with a focus on the problem of training from minimal annotated data, taking an approach of sharing data from multiple tasks to reduce the amount of data for developing a new task.\nAs candidate tasks, we consider the actions that a user might perform via apps on their phone. Typically, a separate slot-filling model would be trained for each app. For example, one model understands queries about classified ads for cars BIBREF1 and another model handles queries about the weather BIBREF2 . As the number of apps increases, this approach becomes impractical due to the burden of collecting and labeling the training data for each model. In addition, using independent models for each task has high storage costs for mobile devices.\nCrowd-sourced data was collected simulating common use cases for four different apps: United Airlines, Airbnb, Greyhound bus service and OpenTable. The corresponding actions are booking a flight, renting a home, buying bus tickets, and making a reservation at a restaurant. In order to elicit natural language, crowd workers were instructed to simulate a conversation with a friend planning an activity as opposed to giving a command to the computer. Workers were prompted with a slot type/value pair and asked to form a reply to their friend using that information. The instructions were to not include any other potential slots in the sentence but this instruction was not always followed by the workers.\nSlot filling models are a useful method for simple natural language understanding tasks, where information can be extracted from a sentence and used to perform some structured action\nAs candidate tasks, we consider the actions that a user might perform via apps on their phone.\nCrowd-sourced data was collected simulating common use cases for four different apps: United Airlines, Airbnb, Greyhound bus service and OpenTable.

        "answer": "Regarding the specific case of SimBA-ODS, we have presented two different epsilon tunings: 0.2 and 2.0. The original value of 0.2 is taken from the original paper/code, and is most likely inherited from the original SimBA work. As it is a fairly inappropriate tuning for this problem, we have also chosen the alternative step length of 2.0 based on the search described in Section A.4 and depicted in Fig. 7 of the appendix. We fix the same value of 2.0 for both GFCS and SimBA-ODS, as it has an identical meaning in both contexts, and is a fair like-for-like comparison.\nWe typically assume that authors have already presented their own papers in the best light possible, with parameters that they themselves optimised for the evaluation, and we always present results using their recommended settings as one of the (possibly multiple) options. However, as noted in Section A.2 of the appendix, we do sometimes take measures to fix competitors’ implementation issues, improving their performance in doing so (as with LeBA’s failure to interpolate between input domains of different sizes). Additionally, as ODS-RGF did not standardise its parameters against P-RGF in its own evaluation (in the manner we have done against SimBA-ODS), we have presented P-RGF using both its own settings and those of ODS-RGF, as discussed in the paper. This is itself a very interesting ablation, given its result.",
        "evidence": "Figure 7: The figure illustrates two sets of curves. The solid curves represent the median query count required to successfully attack the three architectures as a function of the step length, while the dashed curves show the success rate.\nThe simple method we propose in Algorithm 1 accepts a single hyperparameter: the step length ϵ(line 14), which indicates the length of the perturbations to be attempted at each iterate along its candidate direction. We chose 2.0 as the default value for our experiments by performing a small grid search over a held-out set (disjoint from the 2000 examples used in the experiments of the main paper). \nResults for the three architectures used as victim (and ResNet-152 as the single surrogate) are shown in Fig. 7. Note that the figure has two y-axes and two sets of curves: solid and dashed curves should be considered looking at each axis on the left and right hand side of the plot, respectively. Clearly, better performance can be obtained by separately tuning this hyperparameter for each architecture.\nInstead, we simply chose a fixed value that is reasonable for all models, balancing the query count and success rate. Note also the fact that it is possible to achieve an even lower query count if one is willing to sacrifice about 1% of the success rate.\nWe observed that this choice of ϵ is also significantly better than the default one made by SimBA_x005f_x0002_ODS (Tashiro et al., 2020) (i.e. 0.2), and have reported results for both in our experiments.",

        "evidence": "Understanding what people are talking about and how they feel about it is valuable especially for industries which need to know the customers' opinions on their products. Aspect-Based Sentiment Analysis (ABSA) is a branch of sentiment analysis which deals with extracting the opinion targets (aspects) as well as the sentiment expressed towards them. For instance, in the sentence The spaghetti was out of this world., a positive sentiment is mentioned towards the target which is spaghetti. Performing these tasks requires a deep understanding of the language. Traditional machine learning methods such as SVM BIBREF2, Naive Bayes BIBREF3, Decision Trees BIBREF4, Maximum Entropy BIBREF5 have long been practiced to acquire such knowledge. However, in recent years due to the abundance of available data and computational power, deep learning methods such as CNNs BIBREF6, BIBREF7, BIBREF8, RNNs BIBREF9, BIBREF10, BIBREF11, and the Transformer BIBREF12 have outperformed the traditional machine learning techniques in various tasks of sentiment analysis. Bidirectional Encoder Representations from Transformers (BERT) BIBREF13 is a deep and powerful language model which uses the encoder of the Transformer in a self-supervised manner to learn the language model. It has been shown to result in state-of-the-art performances on the GLUE benchmark BIBREF14 including text classification. BIBREF1 show that adding domain-specific information to this model can enhance its performance in ABSA. Using their post-trained BERT (BERT-PT), we add adversarial examples to further improve BERT's performance on Aspect Extraction (AE) and Aspect Sentiment Classification (ASC) which are two major tasks in ABSA. A brief overview of these two sub-tasks is given in Section SECREF3.\nAdversarial examples are a way of fooling a neural network to behave incorrectly BIBREF15. They are created by applying small perturbations to the original inputs. In the case of images, the perturbations can be invisible to human eye, but can cause neural networks to output a completely different response from the true one. Since neural nets make mistakes on these examples, introducing them to the network during the training can improve their performance. This is called adversarial training which acts as a regularizer to help the network generalize better BIBREF0. Due to the discrete nature of text, it is not feasible to produce perturbed examples from the original inputs. As a workaround, BIBREF16 apply this technique to the word embedding space for text classification. Inspired by them and building on the work of BIBREF1, we experiment with adversarial training for ABSA.\nOur contributions are twofold. First, by carrying out an ablation study on the number of training epochs and the values for dropout in the classification layer, we show that there are values that outperform the specified ones for BERT-PT. Second, we introduce the application of adversarial training in ABSA by proposing a novel architecture which combines adversarial training with the BERT language model for AE and ASC tasks. Our experiments show that the proposed model outperforms the best performance of BERT-PT in both tasks.\nSecond, we introduce the application of adversarial training in ABSA by proposing a novel architecture which combines adversarial training with the BERT language model for AE and ASC tasks.",

It is bordered to the north by the Gulf of Finland across from Finland, to the west by the sea across from Sweden, to the south by Latvia, and to the east by Lake Peipus and Russia. The territory of Estonia consists of the mainland, the larger islands of Saaremaa and Hiiumaa, and over 2,200 other islands and islets on the eastern coast of the Baltic Sea, covering a total area of 45,339 square kilometres (17,505 sq mi). The capital city Tallinn and Tartu are the two largest urban areas of the country. The Estonian language is the autochthonous and the official language of Estonia; it is the first language of the majority of its population, as well as the world's second most spoken Finnic language. The land of what is now modern Estonia has been inhabited by Homo sapiens since at least 9,000 BC. The medieval indigenous population of Estonia was one of the last pagan civilisations in Europe to adopt Christianity following the Papal-sanctioned Livonian Crusade in the 13th century. After centuries of successive rule by the Teutonic Order, Denmark, Sweden, and the Russian Empire, a distinct Estonian national identity began to emerge in the mid-19th century. This culminated in the 24 February 1918 Estonian Declaration of Independence from the then warring Russian and German Empires. Democratic throughout most of the interwar period, Estonia declared neutrality at the outbreak of World War II, but the country was repeatedly contested, invaded and occupied, first by the Soviet Union in 1940, then by Nazi Germany in 1941, and was ultimately reoccupied in 1944 by, and annexed into, the USSR as an administrative subunit (Estonian SSR). Throughout the 1944–1991 Soviet occupation, Estonia's de jure state continuity was preserved by diplomatic representatives and the government-in-exile. Following the bloodless Estonian \"Singing Revolution\" of 1988–1990, the nation's de facto independence from the Soviet Union was restored on 20 August 1991. Estonia is a developed country, with a high-income advanced economy. The sovereign state of Estonia is a democratic unitary parliamentary republic, administratively subdivided into 15 maakond (counties). With a population of just over 1.3 million, it is one of the least populous members of the European Union, the Eurozone, the OECD, the Schengen Area, and NATO.

We include AdaBN, Late Fusion, finetuning methods (finetune BN/classifier/feature extractor, regularized finetuning), cross-domain few-shot learning (FLUTE), hypothesis transfer (finetune BN/feature extractor). Note that finetuning feature extractor is equivalent to SHOT (Liang et al., 2020) with supervised instead of unsupervised loss. We have also included additional comparisons with source-free UDA which uses entire unlabelled target dataset in Table 6 and non-source-free few-shot DA in Appendix Section C.4. Overall, our proposed method achieves competitive performance against other source-free few-shot methods. Source-free UDA can achieve better performance than our proposed method in some cases, but at a cost of less data-efficiency and increased model update computation.",
        "evidence": "As far as we know, there are no existing methods designed and evaluated specifically for our sourcefree few-shot DA setting. We apply existing methods in DA and few-shot transfer learning to provide benchmark performance. We compare with AdaBN by replacing source BN statistics with those calculated on target support set, finetuning the source model on BN layers or classifier or feature extractor, finetuning entire model with L 2 or L 2 -SP or DELTA regularization, Late Fusion which averages scores from source and target classifier, and FLUTE which optimizes BN parameters with nearest-centroid classifier. FLUTE assumes the availability of multiple source datasets to train multiple sets of BN parameters for further blending to initialize the finetuning process. Since we only have access to the pre-trained source model in our setting, we reduce FLUTE to the single source dataset case and initialize FLUTE with single source BN parameters. It is conventional to update the classifier when sufficient target samples are available, hence besides implementing with source classifier (SC), we also implement our proposed method with finetuned classifier (FC) and nearestcentroid classifier (NCC). We follow learning settings in for regularized finetuning and use SGD optimizer with momentum and weight decay 0.0004, and L 2 regularization is also added to finetuning on classifier or feature extractor to prevent overfitting. For all other methods that finetune on BN layers, we use Adam optimizer following. We set learning rate 0.001, mini-batch size 32 and epochs 10 for all methods and datasets evaluated.\nFrom Table, we observe that regularized finetuning tends to adapt well at k = 1, but performance can lag behind with larger support sets. AdaBN does not consistently improve adaptation; we show in Appendix Figure that completely replacing source BN statistics degrades performance for VisDA. Overall, finetuning LCCS with source classifier has at least comparable performance with regularized finetuning for small support sets. For larger support sets, finetuning LCCS with NCC has the best performance, with classification accuracy consistently higher than FLUTE which also uses NCC. We also compare our method to L 2 and FLUTE on Office and OfficeHome in Table 16. Though the transfer learning methods produce comparable performance on the easy dataset of Camelyon17 (two classes, two domains), LCCS outperforms on more difficult datasets, which demonstrates the effectiveness of the proposed low-dimensional finetuning strategy.\nLCCS Finetuning vs BN Finetuning: We further study our proposed constrained optimization of BN layer versus the unconstrained alternative of optimizing directly on the high-dimensional BN parameters γ and β in Equation 1, with fixed source classifier. We also evaluate a combination of the two strategies by first finetuning LCCS followed by finetuning BN parameters. From Figure, we see that when the support set is small at k ≤ 3, finetuning LCCS is always better than finetuning BN parameters. The results are mixed at larger k, which is expected since the unconstrained optimization is also less prone to overfit with more samples. In addition, we observe that finetuning LCCS first provides good initialization for further finetuning of BN parameters, and consistently achieves better adaptation performance than finetuning BN parameters alone. We make similar observations when using NCC as classifier in Appendix Section C.5.  Figure: Finetuning LCCS has best performance when support set is extremely small (k ≤ 3).\nWith larger support set (k ≥ 5), finetuning LCCS+BN parameters attains better performance than finetuning BN parameters alone.\nWe additionally compare our proposed method with source-free UDA methods which adapts with entire unlabelled target dataset, including AdaBN, SHOT, SFDA and SDDA, as well as the few-shot method L 2 and FLUTE, in Table on Office and Office-Home. We observe that self-supervision over the entire unlabelled target can produce good adaptation performance. Despite using only 5 samples per class, finetuning LCCS has equal and better adaptation performance than source-free UDA methods in 5 out of 6 domain pairs on Office. SHOT outperforms in the more challenging OfficeHome dataset, which reflects the difficulty of source-free few-shot setting. However, our proposed method performs the best out of the few-shot methods evaluated, which demonstrates its effectiveness in the few-shot setting. We refer readers to Appendix Section C.4 for detailed results and comparisons with nonsource-free few-shot DA methods.\nWe compare the resources of the three source-free methods from different settings: SHOT, Tent, and our fewshot LCCS finetuning. From Table, the number and storage size of samples for our proposed method is much smaller than those used for SHOT. At test time, our method requires no computation for updating the model, which is at least on par with test-time adaptation methods since they can need additional backward passes for online adaptation. For instance, Tent needs at least an additional backward pass. More importantly, our setting is one way to address test-time adaptation's reliance on streaming conditions which may challenge its usefulness in practice.\nWe apply existing methods in DA and few-shot transfer learning to provide benchmark performance. We compare with AdaBN (Li et al., 2016) by replacing source BN statistics with those calculated on target support set, finetuning the source model on BN layers or classifier or feature extractor, finetuning entire model with L2 or L2 -SP (Li et al., 2018) or DELTA (Li et al., 2019) regularization, Late Fusion (Hoffman et al., 2013) which averages scores from source and target classifier, and FLUTE (Triantafillou et al., 2021) which optimizes BN parameters with nearest-centroid classifier.****We additionally compare our proposed method with source-free UDA methods which adapts with entire unlabelled target dataset, including AdaBN (Li et al., 2016), SHOT (Liang et al., 2020), SFDA (Kim et al., 2020) and SDDA (Kurmi et al., 2021), as well as the few-shot method L2 and FLUTE, in Table 6 on Office and Office-Home.****Additionally, we compare with state-of-the-art source-free UDA method SHOT (Liang et al., 2020), which adapts on the entire unlabelled target dataset, on OfficeHome.

Epigenetic modifications are reversible modifications on a cell's DNA or histones that affect gene expression without altering the DNA sequence. Epigenomic maintenance is a continuous process and plays an important role in stability of eukaryotic genomes by taking part in crucial biological mechanisms like DNA repair. Plant flavones are said to be inhibiting epigenomic marks that cause cancers. Two of the most characterized epigenetic modifications are DNA methylation and histone modification. Epigenetic modifications play an important role in gene expression and regulation, and are involved in numerous cellular processes such as in differentiation/development and tumorigenesis.

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nThe conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.",

If it is a known, healthy cat, then you can approach it.  Do so with care so that you do not scare it away.\n\nThere are several techniques to make yourself more approachable.  Ideally, the cat will approach you; you will not approach the cat.\n\nMake yourself look smaller.  Crouch down, and do not look threatening or overly anxious to approach the cat.\n\nTry the \"slow blink.\"  Look at the cat and slowly close and open your eyes.  Also try looking away lazily.  If the cat respond with its own slow blink, that's a good sign.\n\nIf the cat comes near, try offering your hand down low, with the palm turned down.  Hopefully the cat will come to you and rub against the back of your hand.  If so, then you can try petting the cat more actively.",

        "evidence": "Causal documents were chosen to contain one occurrence only of the exact unigrams: `caused', `causing', or `causes'. The word `cause' was not included due to its use as a popular contraction for `because'. One `cause-word' per document restricted the analysis to single relationships between two relata. Documents that contain bidirectional words (`associate', `relate', `connect', `correlate', and any of their stems) were also not selected for analysis. This is because our focus is on causality, an inherently one-sided relationship between two objects. We also did not consider additional synonyms of these cause words, although that could be pursued for future work. Control documents were also selected. These documents did not contain any of `caused', `causing', or `causes', nor any bidirectional words, and are further matched temporally to obtain the same number of control documents as causal documents in each fifteen-minute period during 2013. Control documents were otherwise selected randomly; causal synonyms may be present. The end result of this procedure identified 965,560 causal and 965,560 control documents. Each of the three “cause-words”, `caused', `causes', and `causing' appeared in 38.2%, 35.0%, and 26.8% of causal documents, respectively.\nCausal documents were chosen to contain one occurrence only of the exact unigrams: `caused', `causing', or `causes'.",

        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nFrom our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.",

QA tasks on images BIBREF0 have been widely studied, but most focused on understanding text documents BIBREF1 . A representative dataset in text QA is SQuAD BIBREF1 , in which several end-to-end neural models have accomplished promising performance BIBREF2 . Although there is a significant progress in machine comprehension (MC) on text documents, MC on spoken content is a much less investigated field. In spoken question answering (SQA), after transcribing spoken content into text by automatic speech recognition (ASR), typical approaches use information retrieval (IR) techniques BIBREF3 to find the proper answer from the ASR hypotheses. One attempt towards QA of spoken content is TOEFL listening comprehension by machine BIBREF4 . TOEFL is an English examination that tests the knowledge and skills of academic English for English learners whose native languages are not English. Another SQA corpus is Spoken-SQuAD BIBREF5 , which is automatically generated from SQuAD dataset through Google Text-to-Speech (TTS) system. Recently ODSQA, a SQA corpus recorded by real speakers, is released BIBREF6 .\nTo mitigate the impact of speech recognition errors, using sub-word units is a popular approach for speech-related downstream tasks. It has been applied to spoken document retrieval BIBREF7 and spoken term detection BIBREF8 The prior work showed that, using phonectic sub-word units brought improvements for both Spoken-SQuAD and ODSQA BIBREF5 .\nInstead of considering sub-word features, this paper proposes a novel approach to mitigate the impact of ASR errors. We consider reference transcriptions and ASR hypotheses as two domains, and adapt the source domain data (reference transcriptions) to the target domain data (ASR hypotheses) by projecting these two domains in the shared common space. Therefore, it can effectively benefit the SQA model by improving the robustness to ASR errors in the SQA model.\nDomain adaptation has been successfully applied on computer vision BIBREF9 and speech recognition BIBREF10 .

        "evidence": "Evaluation-I: Strategy Formulation Ability. Table 5 shows the list of inference strategies formulated by LiLi for various INLINEFORM0 and INLINEFORM1 , which control the strategy formulation of LiLi. When INLINEFORM2 , LiLi cannot interact with user and works like a closed-world method. Thus, INLINEFORM3 drops significantly (0.47). When INLINEFORM4 , i.e. with only one interaction per query, LiLi acquires knowledge well for instances where either of the entities or relation is unknown. However, as one unknown entity may appear in multiple test triples, once the entity becomes known, LiLi doesn’t need to ask for it again and can perform inference on future triples causing significant increase in INLINEFORM5 (0.97). When INLINEFORM6 , LiLi is able to perform inference on all instances and INLINEFORM7 becomes 1. For INLINEFORM8 , LiLi uses INLINEFORM9 only once (as only one MLQ satisfies INLINEFORM10 ) compared to INLINEFORM11 . In summary, LiLi’s RL-model can effectively formulate query-specific inference strategies (based on specified parameter values). Evaluation-II: Predictive Performance. Table 6 shows the comparative performance of LiLi with baselines. To judge the overall improvements, we performed paired t-test considering +ve F1 scores on each relation as paired data. Considering both KBs and all relation types, LiLi outperforms Sep with INLINEFORM12 . If we set INLINEFORM13 (training with very few clues), LiLi outperforms Sep with INLINEFORM14 on Freebase considering MCC. Thus, the lifelong learning mechanism is effective in transferring helpful knowledge. Single model performs better than Sep for unknown relations due to the sharing of knowledge (weights) across tasks. However, for known relations, performance drops because, as a new relation arrives to the system, old weights get corrupted and catastrophic forgetting occurs. For unknown relations, as the relations are evaluated just after training, there is no chance for catastrophic forgetting. The performance improvement ( INLINEFORM15 ) of LiLi over F-th on Freebase signifies that the relation-specific threshold INLINEFORM16 works better than fixed threshold 0.5 because, if all prediction values for test instances lie above (or below) 0.5, F-th predicts all instances as +ve (-ve) which degrades its performance. Due to the utilization of contextual similarity (highly correlated with class labels) of entity-pairs, LiLi’s guessing mechanism works better ( INLINEFORM17 ) than blind guessing (BG). The past task selection mechanism of LiLi also improves its performance over w/o PTS, as it acquires more clues during testing for poorly performed tasks (evaluated on validation set). For Freebase, due to a large number of past tasks [9 (25% of 38)], the performance difference is more significant ( INLINEFORM18 ). For WordNet, the number is relatively small [3 (25% of 14)] and hence, the difference is not significant.\nEvaluation-III: User Interaction vs. Performance. Table 7 shows the results of LiLi by varying clue acquisition rate ( INLINEFORM0 ). We use Freebase for tuning INLINEFORM1 due to its higher number of unknown test relations compared to WordNet. LiLi’s performance improves significantly as it acquires more clues from the user. The results on INLINEFORM2 outperforms ( INLINEFORM3 ) that on INLINEFORM4 . Table 8 shows the results of LiLi on user responses to MLQ’s and CLQ’s. Answering MLQ’s and CLQ’s is very hard for simulated users (unlike crowd-sourcing) as often INLINEFORM5 lacks the required triple. Thus, we attempt to analyze how the performance is effected if the user does not respond at all. The results show a clear trend in overall performance improvement when the user responds. However, the improvement is not significant as the simulated user’s query satisfaction rate (1% MLQs and 10% CLQs) is very small. But, the analysis shows the effectiveness of LiLi’s guessing mechanism and continual learning ability that help in achieving avg. +ve F1 of 0.57 and 0.62 on FB and WN respectively with minimal participation of the user.\nEvaluation-II: Predictive Performance. Table 6 shows the comparative performance of LiLi with baselines. To judge the overall improvements, we performed paired t-test considering +ve F1 scores on each relation as paired data.",

        "question": "What method do the authors propose to tackle the raised questions?",
        "answer": "The authors propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions.",
        "evidence": "The pre-trained language model, BERT BIBREF0 has led to a big breakthrough in various kinds of natural language understanding tasks. Ideally, people can start from a pre-trained BERT checkpoint and fine-tune it on a specific downstream task. However, the original BERT models are memory-exhaustive and latency-prohibitive to be served in embedded devices or CPU-based online environments. As the memory and latency constraints vary in different scenarios, the pre-trained BERT model should be adaptive to different requirements with accuracy retained to the largest extent. Existing BERT-oriented model compression solutions largely depend on knowledge distillation BIBREF1, which is inefficient and resource-consuming because a large training corpus is required to learn the behaviors of a teacher. For example, DistilBERT BIBREF2 is re-trained on the same corpus as pre-training a vanilla BERT from scratch; and TinyBERT BIBREF3 utilizes expensive data augmentation to fit the distillation target. The costs of these model compression methods are as large as pre-training and unaffordable for low-resource settings. Therefore, it is straight-forward to ask, can we design a lightweight method to generate adaptive models with comparable accuracy using significantly less time and resource consumption? In this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions. Specifically, LadaBERT is based on an iterative hybrid model compression framework consisting of weighting pruning, matrix factorization and knowledge distillation. Initially, the architecture and weights of student model are inherited from the BERT teacher. In each iteration, the student model is first compressed by a small ratio based on weight pruning and matrix factorization, and is then fine-tuned under the guidance of teacher model through knowledge distillation. Because weight pruning and matrix factorization help to generate better initial and intermediate status\nin the knowledge distillation iterations, the accuracy and efficiency of model compression can be greatly improved.\nWe conduct extensive experiments on five public datasets of natural language understanding. As an example, the performance comparison of LadaBERT and state-of-the-art models on MNLI-m dataset is illustrated in Figure FIGREF1. We can see that LadaBERT outperforms other BERT-oriented model compression baselines at various model compression ratios. Especially, LadaBERT-1 outperforms BERT-PKD significantly under $2.5\\times $ compression ratio, and LadaBERT-3 outperforms TinyBERT under $7.5\\times $ compression ratio while the training speed is accelerated by an order of magnitude.\nThe rest of this paper is organized as follows. First, we summarizes the related works of model compression and their applications to BERT in Section SECREF2. Then, the methodology of LadaBERT is introduced in Section SECREF3, and experimental results are presented in Section SECREF4. At last, we conclude this work and discuss future works in Section SECREF5.\nIn this paper, we propose LadaBERT (Lightweight adaptation of BERT through hybrid model compression) to tackle the raised questions.",

        "question": "What problem does the paper investigate?",
        "answer": "The problem of discriminating between factual and non-factual accounts in Twitter.",
        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter.",

        "question": "What is the Wikipedia article quality assessment in this paper？",
        "answer": "Quality assessment of Wikipedia articles is a task that assigns a quality class label to a given Wikipedia article, mirroring the quality assessment process that the Wikipedia community carries out manually.",
        "evidence": "A variety of approaches have been proposed for document quality assessment across different domains: Wikipedia article quality assessment, academic paper rating, content quality assessment in community question answering (cQA), and essay scoring. Among these approaches, some use hand-crafted features while others use neural networks to learn features from documents. For each domain, we first briefly describe feature-based approaches and then review neural network-based approaches. Wikipedia article quality assessment: Quality assessment of Wikipedia articles is a task that assigns a quality class label to a given Wikipedia article, mirroring the quality assessment process that the Wikipedia community carries out manually. Many approaches have been proposed that use features from the article itself, meta-data features (e.g., the editors, and Wikipedia article revision history), or a combination of the two. Article-internal features capture information such as whether an article is properly organized, with supporting evidence, and with appropriate terminology. For example, BIBREF3 use writing styles represented by binarized character trigram features to identify featured articles. BIBREF4 and BIBREF0 explore the number of headings, images, and references in the article. BIBREF5 use nine readability scores, such as the percentage of difficult words in the document, to measure the quality of the article. Meta-data features, which are indirect indicators of article quality, are usually extracted from revision history, and the interaction between editors and articles. For example, one heuristic that has been proposed is that higher-quality articles have more edits BIBREF6 , BIBREF7 . BIBREF8 use the percentage of registered editors and the total number of editors of an article. Article–editor dependencies have also been explored. For example, BIBREF9 use the authority of editors to measure the quality of Wikipedia articles, where the authority of editors is determined by the articles they edit. Deep learning approaches to predicting Wikipedia article quality have also been proposed. For example, BIBREF10 use a version of doc2vec BIBREF11 to represent articles, and feed the document embeddings into a four hidden layer neural network. BIBREF12 first obtain sentence representations by averaging words within a sentence, and then apply a biLSTM BIBREF13 to learn a document-level representation, which is combined with hand-crafted features as side information. BIBREF14 exploit two stacked biLSTMs to learn document representations.\nAcademic paper rating: Academic paper rating is a relatively new task in NLP/AI, with the basic formulation being to automatically predict whether to accept or reject a paper. BIBREF2 explore hand-crafted features, such as the length of the title, whether specific words (such as outperform, state-of-the-art, and novel) appear in the abstract, and an embedded representation of the abstract as input to different downstream learners, such as logistic regression, decision tree, and random forest. BIBREF15 exploit a modularized hierarchical convolutional neural network (CNN), where each paper section is treated as a module. For each paper section, they train an attention-based CNN, and an attentive pooling layer is applied to the concatenated representation of each section, which is then fed into a softmax layer.\nContent quality assessment in cQA: Automatic quality assessment in cQA is the task of determining whether an answer is of high quality, selected as the best answer, or ranked higher than other answers. To measure answer content quality in cQA, researchers have exploited various features from different sources, such as the answer content itself, the answerer's profile, interactions among users, and usage of the content. The most common feature used is the answer length BIBREF16 , BIBREF17 , with other features including: syntactic and semantic features, such as readability scores. BIBREF18 ; similarity between the question and the answer at lexical, syntactic, and semantic levels BIBREF18 , BIBREF19 , BIBREF20 ; or user data (e.g., a user's status points or the number of answers written by the user). There have also been approaches using neural networks. For example, BIBREF21 combine CNN-learned representations with hand-crafted features to predict answer quality. BIBREF22 use a 2-dimensional CNN to learn the semantic relevance of an answer to the question, and apply an LSTM to the answer sequence to model thread context. BIBREF23 and BIBREF24 model the problem similarly to machine translation quality estimation, treating answers as competing translation hypotheses and the question as the reference translation, and apply neural machine translation to the problem. Essay scoring: Automated essay scoring is the task of assigning a score to an essay, usually in the context of assessing the language ability of a language learner. The quality of an essay is affected by the following four primary dimensions: topic relevance, organization and coherence, word usage and sentence complexity, and grammar and mechanics. To measure whether an essay is relevant to its “prompt” (the description of the essay topic), lexical and semantic overlap is commonly used BIBREF25 , BIBREF26 . BIBREF27 explore word features, such as the number of verb formation errors, average word frequency, and average word length, to measure word usage and lexical complexity. BIBREF28 use sentence structure features to measure sentence variety. The effects of grammatical and mechanic errors on the quality of an essay are measured via word and part-of-speech $n$ -gram features and “mechanics” features BIBREF29 (e.g., spelling, capitalization, and punctuation), respectively. BIBREF30 , BIBREF31 , and BIBREF32 use an LSTM to obtain an essay representation, which is used as the basis for classification. Similarly, BIBREF33 utilize a CNN to obtain sentence representation and an LSTM to obtain essay representation, with an attention layer at both the sentence and essay levels.\nQuality assessment of Wikipedia articles is a task that assigns a quality class label to a given Wikipedia article, mirroring the quality assessment process that the Wikipedia community carries out manually.",

However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nDeep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available.

QE research has grown increasingly popular due to the improved quality of MT systems, and potential for reductions in post-editing time and the corresponding savings in labor costs BIBREF2 , BIBREF3 . QE can be performed on multiple granularities, including at word level, sentence level, or document level. In this paper, we focus on quality estimation at word level, which is framed as the task of performing binary classification of translated tokens, assigning “OK” or “BAD” labels.\nEarly work on this problem mainly focused on hand-crafted features with simple regression/classification models BIBREF4 , BIBREF5 . Recent papers have demonstrated that utilizing recurrent neural networks (RNN) can result in large gains in QE performance BIBREF6 . However, these approaches encode the context of the target word by merely concatenating its left and right context words, giving them limited ability to control the interaction between the local context and the target word.\nIn this paper, we propose a neural architecture, Context Encoding Quality Estimation (CEQE), for better encoding of context in word-level QE. Specifically, we leverage the power of both (1) convolution modules that automatically learn local patterns of surrounding words, and (2) hand-crafted features that allow the model to make more robust predictions in the face of a paucity of labeled data. Moreover, we further utilize stacked recurrent neural networks to capture the long-term dependencies and global context information from the whole sentence.\nWe tested our model on the official benchmark of the WMT18 word-level QE task.

Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches.

        "evidence": "Following developing news stories is imperative to making real-time decisions on important political and public safety matters. Given the abundance of media providers and languages, this endeavor is an extremely difficult task. As such, there is a strong demand for automatic clustering of news streams, so that they can be organized into stories or themes for further processing. Performing this task in an online and efficient manner is a challenging problem, not only for newswire, but also for scientific articles, online reviews, forum posts, blogs, and microblogs.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream. In this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes. For example, for news articles, we would want to cluster them into related news stories.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. Our clustering approach is part of a larger media monitoring project to solve the problem of monitoring massive text and TV/Radio streams (speech-to-text). In particular, media monitors write intelligence reports about the most relevant events, and being able to search, visualize and explore news clusters assists in gathering more insight about a particular story. Since relevant events may be spawned from any part of the world (and from many multilingual sources), it becomes imperative to cluster news across different languages.\nIn terms of granularity, the type of story clusters we are interested in are the group of articles which, for example : (i) Narrate recent air-strikes in Eastern Ghouta (Syria); (ii) Describe the recent launch of Space X's Falcon Heavy rocket.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream.",

        "question": "Why Twitter data is a more suitable resource than blog data?",
        "answer": "Because it is shorter and it is easier to get data containing both sarcastic and non-sarcastic examples of the same event by Twitter API.",
        "evidence": "Sarcasm is defined as “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”. As the fields of affective computing and sentiment analysis have gained increasing popularity BIBREF0 , it is a major concern to detect sarcastic, ironic, and metaphoric expressions. Sarcasm, especially, is key for sentiment analysis as it can completely flip the polarity of opinions. Understanding the ground truth, or the facts about a given event, allows for the detection of contradiction between the objective polarity of the event (usually negative) and its sarcastic characteristic by the author (usually positive), as in “I love the pain of breakup”. Obtaining such knowledge is, however, very difficult.\nIn our experiments, we exposed the classifier to such knowledge extracted indirectly from Twitter. Namely, we used Twitter data crawled in a time period, which likely contain both the sarcastic and non-sarcastic accounts of an event or similar events. We believe that unambiguous non-sarcastic sentences provided the classifier with the ground-truth polarity of those events, which the classifier could then contrast with the opposite estimations in sarcastic sentences. Twitter is a more suitable resource for this purpose than blog posts, because the polarity of short tweets is easier to detect (as all the information necessary to detect polarity is likely to be contained in the same sentence) and because the Twitter API makes it easy to collect a large corpus of tweets containing both sarcastic and non-sarcastic examples of the same event.\nSometimes, however, just knowing the ground truth or simple facts on the topic is not enough, as the text may refer to other events in order to express sarcasm. For example, the sentence “If Hillary wins, she will surely be pleased to recall Monica each time she enters the Oval Office :P :D”, which refers to the 2016 US presidential election campaign and to the events of early 1990's related to the US president Clinton, is sarcastic because Hillary, a candidate and Clinton's wife, would in fact not be pleased to recall her husband's alleged past affair with Monica Lewinsky. The system, however, would need a considerable amount of facts, commonsense knowledge, anaphora resolution, and logical reasoning to draw such a conclusion. In this paper, we will not deal with such complex cases.\nExisting works on sarcasm detection have mainly focused on unigrams and the use of emoticons BIBREF1 , BIBREF2 , BIBREF3 , unsupervised pattern mining approach BIBREF4 , semi-supervised approach BIBREF5 and n-grams based approach BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 with sentiment features. Instead, we propose a framework that learns sarcasm features automatically from a sarcasm corpus using a convolutional neural network (CNN). We also investigate whether features extracted using the pre-trained sentiment, emotion and personality models can improve sarcasm detection performance. Our approach uses relatively lower dimensional feature vectors and outperforms the state of the art on different datasets. In summary, the main contributions of this paper are the following:\nThe rest of the paper is organized as follows: Section SECREF2 proposes a brief literature review on sarcasm detection; Section SECREF4 presents the proposed approach; experimental results and thorough discussion on the experiments are given in Section SECREF5 ; finally, Section SECREF6 concludes the paper.\nTwitter is a more suitable resource for this purpose than blog posts, because the polarity of short tweets is easier to detect (as all the information necessary to detect polarity is likely to be contained in the same sentence) and because the Twitter API makes it easy to collect a large corpus of tweets containing both sarcastic and non-sarcastic examples of the same event.",

Conceptually, an agent-wise utility is similar to an actor in an actor-critic method. This is why we use the word “utility” rather than agent-wise “action-value”. In our revised draft, we further clarified this in Section 3.3.",
        "evidence": "Here, we introduce our architectures for the action-value estimators. First, we construct the estimators using the utility functions z 1 (w agt ), . . . , z N (w agt ) with agent-wise risk level w agt . Our main contribution in designing the estimators is twofold: (i) using IQN for the true action-value estimator Z jt (w env ) with environment-wise risk level w env and (ii) using a monotonic mixing network for the transformed action-value estimators Z tran with agent-wise risk level w agt .\nAgent-wise utility function z i . In a partially observable setting, agents can learn better policies by using their action-observation history τ i instead of their current observation. We represent each agent-wise utility function as a DRQN that receives action-observation history as input and outputs z i for each action and w agt . The utility functions do not estimate the action-value, but aim to accurately extract the optimal action from the joint action-value.\nTrue action-value estimator Z jt . The estimator Z jt aims to express distributions with additional representation power; note that the transformed action-value estimator has limited power due to the decentralization condition (equation 1). For the true action-value estimator, we employ a feed-forward network that takes the state s and set of utility functions z i for i ∈ N . Since we use z averaged over multiple w agt samples, the feed forward network is not conditioned on w agt .\nTo apply IQN for the true action-value estimator, we use an additional network φ that computes an embedding φ(w env ) for the sample point w env . We calculate the embedding of w env with cosine basis functions and utilize element-wise (Hadamard) product, as done in the IQN paper.\nTable: Payoff matrix of the two-step game. N (µ, σ 2 ) denotes the normal distribution with a mean of µ and a variance of σ 2 . For the first step, agent-wise risk-seeking (cooperation) is crucial because the optimal action is (A, A) but taking action A is very risky because when the teammate chooses to be non-cooperative (i.e., by selecting action B or C), a catastrophic reward of -12 is provided. In the second step, handling environment-wise risks is highlighted since there are various combinations of mean and variance depending on joint actions, i.e., N (−1, 10) for the action (C, C) and N (−1, 0) for the action (B, B). Transformed action-value estimator Z tran . The architecture of the transformed action-value estimator is largely the same as the mixing network of. The transformed action-value estimator is expressed as follows:\nwhere θ tran (s, w agt ) is a non-negative parameter obtained from state-dependent hypernetwork. A more detailed discussion is available in Appendix D.\nAgent-wise utility function zi. In a partially observable setting, agents can learn better policies by using their action-observation history τi instead of their current observation. We represent each agent-wise utility function as a DRQN (Hausknecht & Stone, 2015) that receives action-observation history as input and outputs zi for each action and wagt.

The encoder does not need to store the unchanging background pixels in the P‑frame, thus saving space. P‑frames are also known as delta‑frames.\n\nA B‑frame (Bidirectional predicted picture) saves even more space by using differences between the current frame and both the preceding and following frames to specify its content.\n\nP and B frames are also called Inter frames. The order in which the I, P and B frames are arranged is called the Group of pictures.",
        "answer": "I frames, B frames, and P frames are video frame types used in video codecs. I frames can be decoded without reference to any other frames. They are self-contained descriptions of one frame of the video. P frames and B frames on the other hand reference other frames and must be decoded after the frames they reference have been decoded. P frames only reference frames from earlier in the video whereas B frames can reference frames from earlier or later.

        "evidence": "Since the setting is quite different from traditional adversarial attacks, search for link prediction adversaries brings up unique challenges. To find these minimal changes for a target link, we need to identify the fact that, when added into or removed from the graph, will have the biggest impact on the predicted score of the target fact. Unfortunately, computing this change in the score is expensive since it involves retraining the model to recompute the embeddings. We propose an efficient estimate of this score change by approximating the change in the embeddings using Taylor expansion. The other challenge in identifying adversarial modifications for link prediction, especially when considering addition of fake facts, is the combinatorial search space over possible facts, which is intractable to enumerate. We introduce an inverter of the original embedding model, to decode the embeddings to their corresponding graph components, making the search of facts tractable by performing efficient gradient-based continuous optimization. We evaluate our proposed methods through following experiments. First, on relatively small KGs, we show that our approximations are accurate compared to the true change in the score. Second, we show that our additive attacks can effectively reduce the performance of state of the art models BIBREF2 , BIBREF10 up to $27.3\\%$ and $50.7\\%$ in Hits@1 for two large KGs: WN18 and YAGO3-10.

        "question": "Provide a short, bulleted summary of what historians consider the cause of the War of 1812",
        "evidence": "Since the conclusion of the War of 1812, historians have long debated the relative weight of the multiple reasons underlying its origins.\n\nDuring the nineteenth century, historians generally concluded that war was declared largely over national honour, neutral maritime rights and the British seizure of neutral ships and their cargoes on the high seas. This theme was the basis of President James Madison's war message to Congress on June 1, 1812. At the turn of the 20th century, much of the contemporary scholarship re-evaluated this explanation and began to focus more on non-maritime factors as significant contributing causes as well. However, historian Warren H. Goodman warns that too much focus on these ideas can be equally misleading.\n\nIn disagreeing with those interpretations that have simply stressed expansionism and minimized maritime causation, historians have ignored deep-seated American fears for national security, dreams of a continent completely controlled by the republican United States, and the evidence that many Americans believed that the War of 1812 would be the occasion for the United States to achieve the long-desired annexation of Canada. [...] Thomas Jefferson well summarized American majority opinion about the war [...] to say \"that the cession of Canada [...] must be a sine qua non at a treaty of peace.\" - Horsman\n\nHistorian Richard Maass argues that the expansionist theme is a myth that goes against the \"relative consensus among experts that the primary American objective was the repeal of British maritime restrictions\". He says that scholars agree that the United States went to war \"because six years of economic sanctions had failed to bring Britain to the negotiating table, and threatening the Royal Navy's Canadian supply base was their last hope\". Maass agrees that expansionism might have tempted Americans on a theoretical level, but he finds that \"leaders feared the domestic political consequences of doing so\", particularly because such expansion \"focused on sparsely populated western lands rather than the more populous eastern settlements\". To what extent that American leaders considered the question of pursuing territory in Canada, those questions \"arose as a result of the war rather than as a driving cause.\" However, Maass accepts that many historians continue to believe that expansionism was a cause.\n\nReginald Horsman sees expansionism as a secondary cause after maritime issues, noting that many historians have mistakenly rejected expansionism as a cause for the war. He notes that it was considered key to maintaining sectional balance between free and slave states thrown off by American settlement of the Louisiana Territory and widely supported by dozens of War Hawk congressmen such as Henry Clay, Felix Grundy, John Adams Harper and Richard Mentor Johnson, who voted for war with expansion as a key aim. However, Horsman states that in his view \"the desire for Canada did not cause the War of 1812\" and that \"The United States did not declare war because it wanted to obtain Canada, but the acquisition of Canada was viewed as a major collateral benefit of the conflict\".\n\nHowever, other historians believe that a desire to permanently annex Canada was a direct cause of the war.[full citation needed] Carl Benn notes that the War Hawks' desire to annex the Canadas was similar to the enthusiasm for the annexation of Spanish Florida by inhabitants of the American South as both expected war to facilitate expansion into long-desired lands and end support for hostile tribes (Tecumseh's Confederacy in the North and the Creek in the South).\n\nAlan Taylor says that many Democratic-Republican congressmen such as John Adams Harper, Richard Mentor Johnson and Peter Buell Porter \"longed to oust the British from the continent and to annex Canada\". A few Southerners opposed this, fearing an imbalance of free and slave states if Canada was annexed. Anti-Catholicism also caused many to oppose annexing the mainly Catholic Lower Canada, believing its French-speaking inhabitants unfit \"for republican citizenship\".\n\nEven major figures such as Henry Clay and James Monroe expected to keep at least Upper Canada in an easy conquest. Notable American generals such as William Hull issued proclamations to Canadians during the war promising republican liberation through incorporation into the United States. General Alexander Smyth similarly declared to his troops when they invaded Canada that \"you will enter a country that is to become one of the United States. You will arrive among a people who are to become your fellow-citizens\". However, a lack of clarity about American intentions undercut these appeals.\n\nDavid and Jeanne Heidler argue that \"most historians agree that the War of 1812 was not caused by expansionism but instead reflected a real concern of American patriots to defend United States' neutral rights from the overbearing tyranny of the British Navy. That is not to say that expansionist aims would not potentially result from the war\". However, they also argue otherwise, saying that \"acquiring Canada would satisfy America's expansionist desires\", also describing it as a key goal of western expansionists who, they argue, believed that \"eliminating the British presence in Canada would best accomplish\" their goal of halting British support for tribal raids. They argue that the \"enduring debate\" is over the relative importance of expansionism as a factor, and whether \"expansionism played a greater role in causing the War of 1812 than American concern about protecting neutral maritime rights\".\n\nIn the 1960s, the work of Norman K. Risjord, Reginald Horsman, Bradford Perkins and Roger Brown established a new eastern maritime consensus. While these authors approached the origins of the war from many perspectives, they all conceded that British maritime policy was the principal cause of the war.",
        "answer": "Different historians believe the war of 1812 was caused by: \n1. National honor, neutral maritime rights, and naval ship seizures\n2. Desire by the United States to permanently annex Canada\n3. British maritime policy and its perceived threat on the United States",

        "question": "Do the machine learning methods outperform rule-based approaches based on look-ups in dictionaries such as LIWC?",
        "answer": "Yes, they do.",
        "evidence": "As explained in the introduction, the overarching aim of this project is to investigate in how far information conveyed in social media posts can complement more traditional research methods in clinical psychology to get insights into the recovery experience of individuals with a BD diagnosis. Therefore, we will first conduct a systematic literature review of qualitative evidence to establish a solid base of what is already known about personal recovery experiences in BD for the subsequent social media studies.\nOur research questions, which regard the experiences of different populations, lend themselves to several subprojects. First, we will collect and analyse English-language data from westerners. Then, we will address ethnically diverse English-speaking populations and finally multilingual accounts. This has the advantage that we can build data processing and methodological workflows along an increase in complexity of the data collection and analysis throughout the project.\nIn each project phase, we will employ a mixed-methods approach to combine the advantages of quantitative and qualitative methods BIBREF52 , BIBREF53 , which is established in mental health research BIBREF54 , BIBREF55 , BIBREF56 , BIBREF57 and specifically recommended to investigate personal recovery BIBREF58 . Quantitative methods are suitable to study observable behaviour such as language and yield more generalisable results by taking into account large samples. However, they fall short of capturing the subjective, idiosyncratic meaning of socially constructed reality, which is important when studying individuals' recovery experience BIBREF59 , BIBREF22 , BIBREF23 , BIBREF60 . Therefore, we will apply an explanatory sequential research design BIBREF53 , starting with statistical analysis of the full dataset followed by a manual investigation of fewer examples, similar to `distant reading' BIBREF61 in digital humanities.\nSince previous research mainly employed (semi-)structured interviews and we do not expect to necessarily find the same aspects emphasised in unstructured settings, even less so when looking at a more diverse and non-English speaking population, we will not derive hypotheses from existing recovery models for testing on the online data. Instead, we will start off with exploratory quantitative research using comparative analysis tools such as Wmatrix BIBREF62 to uncover important linguistic features, e.g., on keywords and key concepts that occur with unexpected frequency in our collected datasets relative to reference corpora. The underlying assumption is that keywords and key concepts are indicative of certain aspects of personal recovery, such as those specified in the CHIME model BIBREF24 , other previous research BIBREF22 , BIBREF23 , BIBREF60 , or novel ones. Comparing online sources with transcripts of structured interviews or subcorpora originating from different cultural backgrounds might uncover aspects that were not prominently represented in the accounts studied in prior research.\nA specific challenge will be to narrow down the data to parts relevant for personal recovery, since there is no control over the discussed topics compared to structured interviews. To investigate how individuals discuss personal recovery online and what (potentially unrecorded) aspects they associate with it, without a priori narrowing down the search-space to specific known keywords seems like a chicken-and-egg problem. We propose to address this challenge by an iterative approach similar to the one taken in a corpus linguistic study of cancer metaphors BIBREF63 . Drawing on results from previous qualitative research BIBREF24 , BIBREF23 , we will compile an initial dictionary of recovery-related terms. Next, we will examine a small portion of the dataset manually, which will be partly randomly sampled and partly selected to contain recovery-related terms. Based on this, we will be able to expand the dictionary and additionally automatically annotate semantic concepts of the identified relevant text passages using a semantic tagging approach such as the UCREL Semantic Analysis System (USAS) BIBREF64 . Crucially for the multilingual aspect of the project, USAS can tag semantic categories in eight languages BIBREF8 . Then, semantic tagging will be applied to the full corpus to retrieve all text passages mentioning relevant concepts. Furthermore, distributional semantics methods BIBREF65 , BIBREF66 can be used to find terms that frequently co-occur with words from our keyword dictionary. Occurrences of the identified keywords or concepts can be quantified in the full corpus to identify the importance of the related personal recovery aspects.\nLinguistic Inquiry and Word Count (LIWC) BIBREF67 is a frequently used tool in social-science text analysis to analyse emotional and cognitive components of texts and derive features for classification models BIBREF47 , BIBREF46 , BIBREF68 , BIBREF69 . LIWC counts target words organised in a manually constructed hierarchical dictionary without contextual disambiguation in the texts under analysis and has been psychometrically validated and developed for English exclusively. While translations for several languages exist, e.g., Dutch BIBREF9 , and it is questionable to what extent LIWC concepts can be transferred to other languages and cultures by mere translation. We therefore aim to apply and develop methods that require less manual labour and are applicable to many languages and cultures. One option constitute unsupervised methods, such as topic modelling, which has been applied to explore cultural differences in mental-health related online data already BIBREF37 , BIBREF36 . The Differential Language Analysis ToolKit (DLATK) BIBREF70 facilitates social-scientific language analyses, including tools for preprocessing, such as emoticon-aware tokenisers, filtering according to meta data, and analysis, e.g. via robust topic modelling methods.\nFurthermore, emotion and sentiment analysis constitute useful tools to investigate the emotions involved in talking about recovery and identify factors that facilitate or hinder it. There are many annotated datasets to train supervised classifiers BIBREF71 , BIBREF3 for these actively researched NLP tasks. Machine learning methods were found to usually outperform rule-based approaches based on look-ups in dictionaries such as LIWC. Again, most annotated resources are English, but state of the art approaches based on multilingual embeddings allow transferring models between languages BIBREF4 .\nMachine learning methods were found to usually outperform rule-based approaches based on look-ups in dictionaries such as LIWC.",

        "evidence": "Autism therapies include a wide variety of therapies that help people with autism, or their families. Such methods of therapy also seek the increase of functional independence in autistic people. Many therapies marketed towards autistic people and/or their parents claim outcomes that have not been supported by Level of Research (LOE) Level 1 (highest level assigned based on the methodological quality of their design, validity, and applicability to patient care). Level 1 research includes evidence from a systematic review or meta-analysis of all relevant RCTs (randomized controlled trial) or evidence-based clinical practice guidelines based on systematic reviews of RCTs or three or more RCTs of good quality that have similar results.\n\n\nAutism is a neurotype characterized by sensory and communication difference, when compared to neurotypical and allistic individuals.None of these therapies eliminate autism within someone, let alone to a high degree of viability. Autistic children grow up to become autistic adults at risk of burnout and post-traumatic stress disorder (PTSD) inflicted during childhood and adolescence, often overlooked by those who prioritize the elimination of autism over the common well-being of autistic people. Treatment is typically catered to the person's needs. Treatments fall into two major categories: educational interventions and medical management. Training and support are also given to families of those diagnosed with autism spectrum disorders (ASDs)\n\n\nStudies of interventions have some methodological problems that prevent definitive conclusions about efficacy.Although many psychosocial interventions have some positive evidence, suggesting that some form of treatment is preferable to no treatment, the systematic reviews have reported that the quality of these studies has generally been poor, their clinical results are mostly tentative, and there is little evidence for the relative effectiveness of treatment options.Intensive, sustained special education programs and behavior therapy early in life can help children with ASD acquire self-care, social, and job skills,and often can improve functioning, and decrease symptom severity and maladaptive behaviors;Available approaches include applied behavior analysis (ABA), developmental models, structured teaching, speech and language therapy, social skills therapy, and occupational therapy. Occupational therapists work with autistic children by creating interventions that promote social interaction like sharing and cooperation.They also support the autistic child by helping them work through a dilemma as the OT imitates the child and waiting for a response from the child.Educational interventions have some effectiveness in children: intensive ABA treatment has demonstrated effectiveness in enhancing global functioning in preschool children,and is well established for improving intellectual performance of young children.Neuropsychological reports are often poorly communicated to educators, resulting in a gap between what a report recommends and what education is provided.The limited research on the effectiveness of adult residential programs shows mixed results.\n\n\nMany medications are used to treat problems associated with ASD.More than half of U.S. children diagnosed with ASD are prescribed psychoactive drugs or anticonvulsants, with the most common drug classes being antidepressants, stimulants.Aside from antipsychotics,there is scant reliable research about the effectiveness or safety of drug treatments for adolescents and adults with ASD.A person with ASD may respond atypically to medications, the medications can have adverse effects, and no known medication relieves autism's core symptoms of social and communication impairments.\n\n\nAs of 2008 the treatments prescribed to children with ASD were expensive;indirect costs are more so. For someone born in 2000, a U.S. study estimated an average discounted lifetime cost of $4.66 million (2023 dollars, inflation-adjusted from 2003 estimate), with about 10% medical care, 30% extra education and other care, and 60% lost economic productivity.A UK study estimated discounted lifetime costs at £1.9 million and £1.23 million for an autistic person with and without intellectual disability, respectively(2023 pounds, inflation-adjusted from 2005/06 estimate). Legal rights to treatment are complex, vary with location and age, and require advocacy by caregivers. Publicly supported programs are often inadequate or inappropriate for a given child, and unreimbursed out-of-pocket medical or therapy expenses are associated with likelihood of family financial problems;one 2008 U.S. study found a 14% average loss of annual income in families of children with ASD, and a related study found that ASD is associated with higher probability that child care problems will greatly affect parental employment.",

Although InfoboxQA is larger than WikiQA or SelQA, the number of token types ( INLINEFORM1 ) in InfoboxQA is smaller than those two, due to the repetitive nature of infoboxes.\nAll corpora show similar average answer candidate lengths ( INLINEFORM0 ), except for InfoboxQA where each line in the infobox is considered a candidate. SelQA and SQuAD show similar average question lengths ( INLINEFORM1 ) because of the similarity between their annotation schemes. It is not surprising that WikiQA's average question length is the smallest, considering their questions are taken from search queries. InfoboxQA's average question length is relatively small, due to the restricted information that can be asked from the infoboxes.

        "question": "In what areas has ROUGE been used in text summary evaluation?",
        "answer": "Such as news, scientific documents, social media, and question answering.",
        "evidence": "Automatic text summarization has been an active research area in natural language processing for several decades. To compare and evaluate the performance of different summarization systems, the most intuitive approach is assessing the quality of the summaries by human evaluators. However, manual evaluation is expensive and the obtained results are subjective and difficult to reproduce BIBREF0 . To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nROUGE has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC1 (Owczarzak and Dang, 2011).

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation.

        "evidence": "Word embeddings are representations of words in numerical form, as vectors of typically several hundred dimensions. The vectors are used as an input to machine learning models; for complex language processing tasks these are typically deep neural networks. The embedding vectors are obtained from specialized learning tasks, based on neural networks, e.g., word2vec BIBREF0, GloVe BIBREF1, FastText BIBREF2, ELMo BIBREF3, and BERT BIBREF4. For training, the embeddings algorithms use large monolingual corpora that encode important information about word meaning as distances between vectors. In order to enable downstream machine learning on text understanding tasks, the embeddings shall preserve semantic relations between words, and this is true even across languages.\nProbably the best known word embeddings are produced by the word2vec method BIBREF5. The problem with word2vec embeddings is their failure to express polysemous words. During training of an embedding, all senses of a given word (e.g., paper as a material, as a newspaper, as a scientific work, and as an exam) contribute relevant information in proportion to their frequency in the training corpus. This causes the final vector to be placed somewhere in the weighted middle of all words' meanings. Consequently, rare meanings of words are poorly expressed with word2vec and the resulting vectors do not offer good semantic representations. For example, none of the 50 closest vectors of the word paper is related to science.\nThe idea of contextual embeddings is to generate a different vector for each context a word appears in and the context is typically defined sentence-wise. To a large extent, this solves the problems with word polysemy, i.e. the context of a sentence is typically enough to disambiguate different meanings of a word for humans and so it is for the learning algorithms. In this work, we describe high-quality models for contextual embeddings, called ELMo BIBREF3, precomputed for seven morphologically rich, less-resourced languages: Slovenian, Croatian, Finnish, Estonian, Latvian, Lithuanian, and Swedish. ELMo is one of the most successful approaches to contextual word embeddings. At time of its creation, ELMo has been shown to outperform previous word embeddings BIBREF3 like word2vec and GloVe on many NLP tasks, e.g., question answering, named entity extraction, sentiment analysis, textual entailment, semantic role labeling, and coreference resolution.\nThis report is split into further five sections. In section SECREF2, we describe the contextual embeddings ELMo. In Section SECREF3, we describe the datasets used and in Section SECREF4 we describe preprocessing and training of the embeddings.

So you can find some local tennis group classes for him, or even semi-private lessons with qualified coaches. \nIf he is over 10, and he has some basic level skills already, he could attend some tournament (USTA junior circuit, L7 or even L6), or he could join one USTA jtt team, to play for the team with his friends. Also at this age and level, it is also good to have one private coach for him.\nIf he has already shown some competitive skills in this sport, you could also find some \"big\" tournaments, for example, Little Mo Tournament which is national wide tournament for young kids.

It should be soft enough to poke through with a fork. Discard the water. Smash the cooked ground root until an even paste is formed. For a smoother paste, use a food processor or blender. Incorporate the sugar while the paste is still hot. Set aside. Add your boba to a pot of boiling water. Add 2 teaspoon of sugar and allow this boil for 5-7 minutes. Once the boba begin to float these are done. Adjust the timing depending on how firm or soft you prefer them. Remove from hot water and set them aside. Brew the ceylon and let this mix well with fresh ground root paste and condensed milk. Finally, add the milk and tapioca pearls to the mixture. Serve the taro milk tea hot or cold.\n\n\nSweet Potato Pie\n\nIngredients\n3 medium sweet potatoes, baked\n1/2 cup butter\n1 cup granulated sugar\n2 teaspoons vanilla extract\n2 large eggs beaten\n1/2 cup milk, whole or evaporated\n1 (9-inch) unbaked pie crust\nOptional Toppings\nwhipped cream\nmarshmallow fluff\n\nInstructions\n\nPreheat the oven to 400º F. Scrub the sweet potatoes until clean, prick them 4 to 5 times with a fork. Place onto a baking sheet and bake for 45 - 50 minutes until the sweet potatoes are tender when pricked with a toothpick. Remove from the oven and allow to cool until they can easily be handled. Peel the skin from the sweet potatoes and place the sweet potatoes into a large mixing bowl. Reduce the oven heat to 350º F.\nAdd butter to the sweet potatoes and mash until smooth. Add the sugar(s) to the sweet potatoes and mix until well combined. Add the vanilla extract, milk, and the eggs. Mix until well combined. Pour into the unbaked pie crust.\nBake the pie until the center of the pie is set, about 1 hour. Remove the pie from the oven and allow to cool slightly.\nServe the pie warm or allow to cool before slicing. Top with whipped cream (or your favorite topping) and serve.\n\n\nGnocchi\n\nIngredients\n2 potatoes, peeled\n2 cups all-purpose flour\n1 egg\n\nInstructions\nBring a large pot of salted water to a boil; add potatoes and cook until tender but still firm, about 15 minutes. Drain, cool, and mash with a fork or potato masher.\nCombine 1 cup mashed potato, flour, and egg in a large bowl. Knead until dough forms a ball. Shape small portions of the dough into long \"snakes\". On a floured surface, cut snakes into 1/2-inch pieces.\nBring a large pot of lightly salted water to a boil. Drop in gnocchi and cook for 3 to 5 minutes or until gnocchi have risen to the top; drain and serve.\n\n\nPotato Latkes\n\nIngredients\n2 1/2 pounds baking potatoes, coarsely shredded \n1 medium onion, coarsely shredded \n2 large eggs, beaten\n2 teaspoons kosher salt\n1/2 teaspoon black pepper\nVegetable oil, for frying\nApplesauce, sour cream, smoked salmon and salmon roe, for serving\n\nInstructions\nIn a colander set over a large bowl, toss the potatoes with the onion and squeeze dry. Let the potatoes and onion drain for 2 to 3 minutes, then pour off the liquid in the bowl, leaving the starchy paste at the bottom. Add the potatoes and onion, along with the eggs, salt, pepper and mix well.\n\nIn a large skillet, heat an 1/8-inch layer of oil until shimmering. Spoon 1/4-cup mounds of the latke batter into the skillet about 2 inches apart and flatten slightly with a spatula. Fry the latkes over moderately high heat, turning once, until golden and crisp, 5 to 7 minutes. Transfer the latkes to paper towels to drain, then transfer to a platter. Repeat to make the remaining latkes, adding more oil to the skillet as needed. \nServe with applesauce, sour cream, smoked salmon and salmon roe.\n\n\nPoutine\n\nIngredients\n3 or 4 large russet potatoes ( 3 to 4 pounds total), peeled and cut into 1/3-inch-wide sticks\n2 tablespoons extra-virgin olive oil\n1 teaspoon sea salt\n1 1/2 teaspoons dried thyme\nFreshly cracked black pepper\n4 tablespoons (½ stick) unsalted butter\n1/4 cup all-purpose flour\n3/4 teaspoon garlic powder\n½ teaspoon onion powder\n1 cup chicken broth\n1 cup beef broth\n1 ½ teaspoons Worcestershire sauce\n1 teaspoon Better Than Bouillon beef base or 1 beef bouillon cube\n1 teaspoon unfiltered apple cider vinegar\n10 ounces white cheddar cheese curds, at room temperature\nMinced fresh parsley\n\nInstructions\nMake the fries. Place the batons in a large bowl and cover them with cold water. Let soak for at least 30 minutes up to 24 hours for crispier fries.\nPreheat the oven to 425°F. Line 2 large rimmed baking sheets with parchment paper.\nSpread the potatoes out onto large, clean kitchen towels. Dry them off as best as possible. Place the potatoes on the prepared baking sheets, drizzle with the olive oil, sprinkle with the thyme and salt and add black pepper to taste. Toss to coat evenly, then spread out the potatoes into a single layer.\nBake for 10 minutes, then toss the fries and rotate the pans, swapping the one on the top for the one on the bottom. Increase the oven to 450°F and bake the fries for 10 minutes more.Toss the fries and swap the pans from top to bottom again. Turn on the broiler and cook the fries until they are beginning to brown and crisp, about 5 more minutes. Continue to toss and broil until the fries reach your desired doneness. Season with salt and pepper.\nMeanwhile, make the gravy. In a large saucepan set over medium heat, melt the butter. Sprinkle the flour over the butter and cook, stirring constantly, until golden brown, about 2 minutes. Stir in the garlic powder and onion powder. Slowly add the chicken and beef broth. Increase the heat to medium high and bring to a boil, stirring often. Reduce the heat to low and simmer until thickened. Stir in the Worcestershire, beef bouillon, and vinegar. Season with salt and pepper.\nTo assemble the poutine, divide the fries among 4 plates. Sprinkle it with the cheese curds, drizzle on the gravy, and garnish with parsley. Serve immediately.",

His democratization measures and formation of the elected Congress of People's Deputies undermined the one-party state. Gorbachev declined to intervene militarily when various Eastern Bloc countries abandoned Marxist–Leninist governance in 1989–1992. Internally, growing nationalist sentiment threatened to break up the Soviet Union, leading Marxist–Leninist hardliners to launch the unsuccessful August Coup against Gorbachev in 1991.

        "evidence": "As an essential part of a task-oriented dialogue system BIBREF0 , the task of natural language generation (NLG) is to produce a natural language utterance containing the desired information given a semantic representation consisting of dialogue act types with a set of slot-value pairs. Conventional methods using hand-crafted rules often generates monotonic utterances and it requires substantial amount of human engineering work. Recently, various neural approaches BIBREF1 , BIBREF2 , BIBREF3 have been proposed to generate accurate, natural and diverse utterances. However, these methods are typically developed for particular domains. Moreover, they are often data-intensive to train. The high annotation cost prevents developers to build their own NLG component from scratch. Therefore, it is extremely useful to train a NLG model that can be generalized to other NLG domains or tasks with a reasonable amount of annotated data. This is referred to low-resource NLG task in this paper.\nRecently, some methods have been proposed for low-resource NLG tasks. Apart from the simple data augmentation trick BIBREF4 , specialized model architectures, including conditional variational auto-encoders (CVAEs, BIBREF3 , BIBREF5 , BIBREF6 ) and adversarial domain adaptation critics BIBREF5 , have been proposed to learn domain-invariant representations. Although promising results were reported, we found that datasets used by these methods are simple which tend to enumerate many slots and values in an utterance without much linguistic variations. As a consequence, over-fitting the slots and values in the low-resource target domain could even outperform those versions trained with rich source domain examples BIBREF6 . Fortunately, there is a new large-scale dialog dataset (MultiWoz, BIBREF7 ) that contains a great variety of domains and linguistic patterns that allows us to conduct extensive and meaningful experimental analysis for low-resource NLG tasks.\nIn this paper, instead of casting the problem as model-based approaches, we propose a generalized optimization-based meta-learning approach to directly enhance the optimization procedure for the low-resource NLG task. We start by arguing that a recently proposed model-agnostic meta-learning algorithm (MAML, BIBREF8 ) is a nice fit to the low-resource NLG task. Then, we proposed a generalized NLG algorithm called Meta-NLG based on MAML by viewing languages in different domains or dialog act types as separate Meta NLG tasks. Following the essence of MAML, the goal of Meta-NLG is to learn a better initialization of model parameters that facilitates fast adaptation to new low-resource NLG scenarios. As Meta-NLG is model-agnostic as long as the model can be optimized by gradient descent, we could apply it to any existing NLG models to optimize them in a way that adapt better and faster to new low-resource tasks.\nThe main contribution of this paper is two-fold:\nAlthough promising results were reported, we found that datasets used by these methods are simple which tend to enumerate many slots and values in an utterance without much linguistic variations.",

        "evidence": "We automatically create a test set from the OpenSubtitles corpus BIBREF22 . The goal is to provide a large number of difficult test cases where an English pronoun has to be translated to a German pronoun.\nThe most challenging cases are translating it to either er, sie or es, depending on the grammatical gender of the antecedent. Not only is the translation of it ambiguous, there is also class imbalance in the training data (see Table TABREF18 ). There is roughly a 30% probability that it is aligned to es, which makes it difficult to learn to translate er and sie. We use parsing and automatic co-reference resolution to find translation pairs that satisfy our constraints.\nTo provide a basis for filtering with constraints, we tokenize the whole data set with the Moses tokenizer, generate symmetric word alignments with fast_align BIBREF23 , parse the English text with CoreNLP BIBREF24 , parse the German text with ParZu BIBREF25 and perform coreference resolution on both sides. The coreference chains are obtained with the neural model of CoreNLP for English, and with CorZu for German BIBREF26 , respectively.\nThen we opt for high-precision, aggressive filtering, according to the following protocol: for each pair of sentences INLINEFORM0 in English and German, extract iff\n INLINEFORM0 contains the English pronoun it, and INLINEFORM1 contains a German pronoun that is third person singular (er, sie or es), as indicated by their part-of-speech tags;\nthose pronouns are aligned to each other;\nboth pronouns are in a coreference chain;\ntheir nominal antecedents in the coreference chain are aligned on word level.\nThis removes most candidate pairs, but is necessary to overcome the noise introduced by our preprocessing pipeline, most notably coreference resolution. From the filtered set, we create a balanced test set by randomly sampling 4000 instances of each of the three translations of it under consideration (er, sie, es). We do not balance antecedent distance. See Table TABREF25 for the distribution of pronoun pairs and antecedent distance in the test set.\nFor each sentence pair in the resulting test set, we introduce contrastive translations. A contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one. For an example, see Table TABREF19 , where the pronoun it in the original translation corresponds to sie because the antecedent bat is a feminine noun in German (Fledermaus). We produce wrong translations by replacing sie with one of the other pronouns (er, es).\nNote that, by themselves, these contrastive translations are grammatically correct if the antecedent is outside the current sentence. The test set also contains pronouns with an antecedent in the same sentence (antecedent distance 0). Those examples do not require any additional context for disambiguation and we therefore expect the sentence-level baseline to perform well on them.\nWe take extra care to ensure that the resulting contrastive translations are grammatically correct, because ungrammatical sentences are easily dismissed by an NMT system. For instance, if there are any possessive pronouns (such as seine) in the sentence, we also change their gender to match the personal pronoun replacement.\nThe German coreference resolution system does not resolve es because most instances of es in German are either non-referential forms, or they refer to a clause instead of a nominal antecedent. We limit the test set to nominal antecedents, as these are the only ambiguous cases with respect to translation. For this reason, we have to rely entirely on the English coreference links for the extraction of sentence pairs with it INLINEFORM0 es, as opposed to pairs with it INLINEFORM1 er and it INLINEFORM2 sie where we have coreference chains in both languages.\nOur extraction process respects document boundaries, to ensure we always search for the right context. We extract additional information from the annotated documents, such as the distance (in sentences) between pronouns and their antecedents, the document of origin, lemma, morphology and dependency information if available.\nTo provide a basis for filtering with constraints, we tokenize the whole data set with the Moses tokenizer, generate symmetric word alignments with fast_align (Dyer et al., 2013), parse the English text with CoreNLP (Manning et al., 2014), parse the German text with ParZu (Sennrich et al., 2013) and perform coreference resolution on both sides.",

However, we believe that the ultimate measure for abuse mitigation should come from users interacting with the system. chin2019should make a first step into this direction by investigating different response styles (Avoidance, Empathy, Counterattacking) to verbal abuse, and recording the user's emotional reaction – hoping that eliciting certain emotions, such as guilt, will eventually stop the abuse.

BIBREF29 report that a pilot using a similar setup let to unnatural interactions, which limits the conclusions we can draw about the effectiveness of abuse mitigation strategies.

        "evidence": "There have been many implementations of the word2vec model in either of the two architectures it provides: continuous skipgram and CBoW (BIBREF0). Similar distributed models of word or subword embeddings (or vector representations) find usage in sota, deep neural networks like BERT and its successors (BIBREF1, BIBREF2, BIBREF3). These deep networks generate contextual representations of words after been trained for extended periods on large corpora, unsupervised, using the attention mechanisms (BIBREF4).\nIt has been observed that various hyper-parameter combinations have been used in different research involving word2vec with the possibility of many of them being sub-optimal (BIBREF5, BIBREF6, BIBREF7). Therefore, the authors seek to address the research question: what is the optimal combination of word2vec hyper-parameters for intrinsic and extrinsic NLP purposes? There are astronomically high numbers of combinations of hyper-parameters possible for neural networks, even with just a few layers. Hence, the scope of our extensive work over three corpora is on dimension size, training epochs, window size and vocabulary size for the training algorithms (hierarchical softmax and negative sampling) of both skipgram and CBoW. The corpora used for word embeddings are English Wiki News Abstract by BIBREF8 of about 15MB, English Wiki Simple (SW) Articles by BIBREF9 of about 711MB and the Billion Word (BW) of 3.9GB by BIBREF10. The corpus used for sentiment analysis is the IMDb dataset of movie reviews by BIBREF11 while that for NER is Groningen Meaning Bank (GMB) by BIBREF12, containing 47,959 sentence samples. The IMDb dataset used has a total of 25,000 sentences with half being positive sentiments and the other half being negative sentiments. The GMB dataset has 17 labels, with 9 main labels and 2 context tags. It is however unbalanced due to the high percentage of tokens with the label 'O'. This skew in the GMB dataset is typical with NER datasets.\nThe objective of this work is to determine the optimal combinations of word2vec hyper-parameters for intrinsic evaluation (semantic and syntactic analogies) and extrinsic evaluation tasks (BIBREF13, BIBREF14), like SA and NER. It is not our objective in this work to record sota results. Some of the main contributions of this research are the empirical establishment of optimal combinations of word2vec hyper-parameters for NLP tasks, discovering the behaviour of quality of vectors viz-a-viz increasing dimensions and the confirmation of embeddings being task-specific for the downstream. The rest of this paper is organised as follows: the literature review that briefly surveys distributed representation of words, particularly word2vec; the methodology employed in this research work; the results obtained and the conclusion.\nThe objective of this work is to determine the optimal combinations of word2vec hyper-parameters for intrinsic evaluation (semantic and syntactic analogies) and extrinsic evaluation tasks, like SA and NER.",

To test this possibility, we compared SoftHebb with PCA and k-means. We used 100 neurons, principal components, or centroids respectively. In PCA and k-means we then treated the learned coefficients as weight vectors of neurons and applied an activation function to then train a supervised classifier on top. First we attempted softmax as in SoftHebb. However the unperturbed test accuracy achieved at convergence was much lower. For example, on MNIST, k-means only reached an accuracy of 53.64% and PCA 28.55%, whereas SoftHebb reached 91.06. Therefore, we performed the experiment again, but with ReLU activation for k-means and PCA, reaching 90.61% and 82.74% respectively. Then we tested for robustness, revealing that SoftHebb’s learned features are in fact more robust than those of other unsupervised algorithms (Fig. 6). For completeness, we also include the hard WTA network, which is essentially a special case of SoftHebb with very high base in the softmax (Section 2.7), and is therefore learning equally robust features.",

United States, 323 U.S. 214 (1944), was a landmark decision by the Supreme Court of the United States to uphold the exclusion of Japanese Americans from the West Coast Military Area during World War II. The decision has been widely criticized, with some scholars describing it as \"an odious and discredited artifact of popular bigotry\", and as \"a stain on American jurisprudence\". The case is often cited as one of the worst Supreme Court decisions of all time. Chief Justice John Roberts repudiated the Korematsu decision in his majority opinion in the 2018 case of Trump v. Hawaii.\n\nIn the aftermath of Imperial Japan's attack on Pearl Harbor, President Franklin D. Roosevelt had issued Executive Order 9066 on February 19, 1942, authorizing the U.S. War Department to create military areas from which any or all Americans might be excluded. Subsequently, the Western Defense Command, a U.S. Army military command charged with coordinating the defense of the West Coast of the United States, ordered \"all persons of Japanese ancestry, including aliens and non-aliens\" to relocate to internment camps. However, a 23-year-old Japanese-American man, Fred Korematsu, refused to leave the exclusion zone and instead challenged the order on the grounds that it violated the Fifth Amendment.\n\nIn a majority opinion joined by five other justices, Associate Justice Hugo Black held that the need to protect against espionage by Japan outweighed the rights of Americans of Japanese ancestry. Black wrote that \"Korematsu was not excluded from the Military Area because of hostility to him or his race\", but rather \"because the properly constituted military authorities ... decided that the military urgency of the situation demanded that all citizens of Japanese ancestry be segregated from the West Coast\" during the war against Japan. Dissenting justices Frank Murphy, Robert H. Jackson, and Owen J.

I'd been skiing and snowboarding for years. One winter I had a snowboarding accident and slid into a tree. Snowboarding requires larger turns with a bigger radius. I wasn't able to turn in time to avoid the tree. \n\nReliability - The thing about being on only a single piece of equipment is that your balance relies much more on the snow conditions. Under ideal conditions, its great to be able to snowboard and maintain control with the edge. Skiing on powder is also a dream. However, if the conditions are less than ideal, then snowboarding on ice becomes a dangerous, out of control situation. Skiing on ice is also no picnic, but at least you can stabilize and balance on your two skis. \n\nExpediency - Skiing with friends inevitably means that you are waiting for the slowest one before you can start down the mountain. I was that friend. Snowboarders have to sit down and strap in, while skiers can pretty much get right off the lift and start down the mountain immediately. This makes mixed groups of skiers and snowboarders the trickiest. So I would sometimes snowboard if I was traveling with snowboarders, and ski if I was traveling with skiers.",

We use Chinese pre-trained BERT BIBREF23 for initialization and then fine-tune the parameters on CrossWOZ. We obtain word embeddings and the sentence representation (embedding of [CLS]) from BERT. Since there may exist more than one intent in an utterance, we modify the traditional method accordingly. For dialogue acts of inform and recommend intents such as (intent=Inform, domain=Attraction, slot=fee, value=free) whose values appear in the sentence, we perform sequential labeling using an MLP which takes word embeddings (\"free\") as input and outputs tags in BIO schema (\"B-Inform-Attraction-fee\"). For each of the other dialogue acts (e.g., (intent=Request, domain=Attraction, slot=fee)) that do not have actual values, we use another MLP to perform binary classification on the sentence representation to predict whether the sentence should be labeled with this dialogue act. To incorporate context information, we use the same BERT to get the embedding of last three utterances. We separate the utterances with [SEP] tokens and insert a [CLS] token at the beginning. Then each original input of the two MLP is concatenated with the context embedding (embedding of [CLS]), serving as the new input. We also conducted an ablation test by removing context information. We trained models with both system-side and user-side utterances.\nModel: We implemented a rule-based model (RuleDST) and adapted TRADE (Transferable Dialogue State Generator) BIBREF19 in this experiment. RuleDST takes as input the previous system state and the last user dialogue acts. Then, the system state is updated according to hand-crafted rules. For example, If one of user dialogue acts is (intent=Inform, domain=Attraction, slot=fee, value=free), then the value of the \"fee\" slot in the attraction domain will be filled with \"free\". TRADE generates the system state directly from all the previous utterances using a copy mechanism. As mentioned in Section SECREF18, the first query of the system often records full user constraints, while the last one records relaxed constraints for recommendation. Thus the last one involves system policy, which is out of the scope of state tracking. We used the first query for these models and left state tracking with recommendation for future work.\nModel: We adapted a vanilla policy trained in a supervised fashion from ConvLab-2 (SL policy). The state $s$ consists of the last system dialogue acts, last user dialogue acts, system state of the current turn, the number of entities that satisfy the constraints in the current domain, and a terminal signal indicating whether the user goal is completed. The action $a$ is delexicalized dialogue acts of current turn which ignores the exact values of the slots, where the values will be filled back after prediction.\nWe adapted BERTNLU from ConvLab-2. \nWe implemented a rule-based model (RuleDST) and adapted TRADE (Transferable Dialogue State Generator) BIBREF19 in this experiment. \nWe adapted a vanilla policy trained in a supervised fashion from ConvLab-2 (SL policy).

        "question": "What components does the HRED dialog model consist of?",
        "answer": "An utterance encoder, a context encoder, and a decoder.",
        "evidence": "We now describe our general model for forecasting future conversational events. Our model integrates two components: (a) a generative dialog model that learns to represent conversational dynamics in an unsupervised fashion; and (b) a supervised component that fine-tunes this representation to forecast future events. Figure FIGREF13 provides an overview of the proposed architecture, henceforth CRAFT (Conversational Recurrent Architecture for ForecasTing).\nTerminology. For modeling purposes, we treat a conversation as a sequence of $N$ comments $C = \\lbrace c_1,\\dots ,c_N\\rbrace $. Each comment, in turn, is a sequence of tokens, where the number of tokens may vary from comment to comment. For the $n$-th comment ($1 \\le n \\le N)$, we let $M_n$ denote the number of tokens. Then, a comment $c_n$ can be represented as a sequence of $M_n$ tokens: $c_n = \\lbrace w_1,\\dots ,w_{M_n}\\rbrace $.\nGenerative component. For the generative component of our model, we use a hierarchical recurrent encoder-decoder (HRED) architecture BIBREF60, a modified version of the popular sequence-to-sequence (seq2seq) architecture BIBREF61 designed to account for dependencies between consecutive inputs. BIBREF23 showed that HRED can successfully model conversational context by encoding the temporal structure of previously seen comments, making it an ideal fit for our use case. Here, we provide a high-level summary of the HRED architecture, deferring deeper technical discussion to BIBREF60 and BIBREF23.\nAn HRED dialog model consists of three components: an utterance encoder, a context encoder, and a decoder. The utterance encoder is responsible for generating semantic vector representations of comments. It consists of a recurrent neural network (RNN) that reads a comment token-by-token, and on each token $w_m$ updates a hidden state $h^{\\text{enc}}$ based on the current token and the previous hidden state:\nwhere $f^{\\text{RNN}}$ is a nonlinear gating function (our implementation uses GRU BIBREF62). The final hidden state $h^{\\text{enc}}_M$ can be viewed as a vector encoding of the entire comment.\nRunning the encoder on each comment $c_n$ results in a sequence of $N$ vector encodings. A second encoder, the context encoder, is then run over this sequence:\nEach hidden state $h^{\\text{con}}_n$ can then be viewed as an encoding of the full conversational context up to and including the $n$-th comment. To generate a response to comment $n$, the context encoding $h^{\\text{con}}_n$ is used to initialize the hidden state $h^{\\text{dec}}_{0}$ of a decoder RNN. The decoder produces a response token by token using the following recurrence:\nwhere $f^{\\text{out}}$ is some function that outputs a probability distribution over words; we implement this using a simple feedforward layer. In our implementation, we further augment the decoder with attention BIBREF63, BIBREF64 over context encoder states to help capture long-term inter-comment dependencies. This generative component can be pre-trained using unlabeled conversational data.\nPrediction component. Given a pre-trained HRED dialog model, we aim to extend the model to predict from the conversational context whether the to-be-forecasted event will occur. Our predictor consists of a multilayer perceptron (MLP) with 3 fully-connected layers, leaky ReLU activations between layers, and sigmoid activation for output. For each comment $c_n$, the predictor takes as input the context encoding $h^{\\text{con}}_n$ and forwards it through the MLP layers, resulting in an output score that is interpreted as a probability $p_{\\text{event}}(c_{n+1})$ that the to-be-forecasted event will happen (e.g., that the conversation will derail).\nTraining the predictive component starts by initializing the weights of the encoders to the values learned in pre-training. The main training loop then works as follows: for each positive sample—i.e., a conversation containing an instance of the to-be-forecasted event (e.g., derailment) at comment $c_e$—we feed the context $c_1,\\dots ,c_{e-1}$ through the encoder and classifier, and compute cross-entropy loss between the classifier output and expected output of 1. Similarly, for each negative sample—i.e., a conversation where none of the comments exhibit the to-be-forecasted event and that ends with $c_N$—we feed the context $c_1,\\dots ,c_{N-1}$ through the model and compute loss against an expected output of 0.\nNote that the parameters of the generative component are not held fixed during this process; instead, backpropagation is allowed to go all the way through the encoder layers. This process, known as fine-tuning, reshapes the representation learned during pre-training to be more directly useful to prediction BIBREF55.\nWe implement the model and training code using PyTorch, and we are publicly releasing our implementation and the trained models together with the data as part of ConvoKit.\n\nAn HRED dialog model consists of three components: an utterance encoder, a context encoder, and a decoder.

Lauder made the claim that lipstick sales could be an economic indicator, in that purchases of cosmetics – lipstick in particular – tend to be inversely correlated to economic health. The speculation was that women substitute lipstick for more expensive purchases like dresses and shoes in times of economic distress.\nLauder identified the Lipstick index as sales across the Estee Lauder family of brands. Subsequent recessions, including the late-2000s recession, provided controverting evidence to Lauder's claims, as sales have actually fallen with reduced economic activity. Conversely, lipstick sales have experienced growth during periods of increased economic activity. As a result, the lipstick index has been discredited as an economic indicator. The increased sales of cosmetics in 2001 has since been attributed to increased interest in celebrity-designed cosmetics brands.\nIn the 2010s, many media outlets reported that with the rise of nail art as fad in the English-speaking countries and as far afield as Japan and the Philippines, nailpolish had replaced lipstick as the main affordable indulgence for women in place of bags and shoes during recession, leading to talk of a nail polish index.Similar sentiment was noted during the coronavirus pandemic, when the mandated use of face masks to prevent the spread of the disease resulted in an increase of eye makeup purchases, suggesting a Mascara index",

        "question": "Is the lacavore diet beneficial?",
        "evidence": "",
        "answer": "While it is harmful to the world trade and transportation of foods, the locavore diet is generally beneficial to the environment, local farmers, and people. In a small community, the locavore diet would contribute to the local economy as well as the health of the population.\n\tThe locavore diet is a restriction in which people are encouraged to eat foods produced within a 100 mile radius of them, which not only benefits their health, as they are eating organic, locally produced foods, but also local farmers, by buying their produce, and the environment, by eliminating the harmful effects of transportation, such as airplanes and trucks.\nA common concern of younger generations is the state of our environment, thanks to the continuation of air and water pollution as well as global warming. The locavore diet targets these exact concerns. In Source A, Maiser notes that a study from the journal Food Policy in 2005 found that buying locally produced foods eliminated the environmental damage that most food transportation causes. The locavore diet is not only friendly to the environment but also to the farmers who produce organic foods. In the USA, the increased purchasing of local foods has created a revival of small farms, with the number of small farms rising 20%, or approximately 1.2 million farms, in just the past six years (Source E). In small communities where small farms are a main source of produce, the locavore diet benefits the local economy, as more money is spent on local farmers and businesses. The increase in small farms within America is also beneficial to the national economy, as money is being spent within the country and perpetuates within our economy.\nDespite its benefits to local farmers, farmers from around the world who were dependent upon the trade and transportation of foods have been suffering. For example, Kenya is responsible for most of the UK’s green beans, and while the locavore diet would support local farmers in the UK, approximately 1.5 million of Kenyan farmers’ livelihoods would be threatened. However, the same argument could be applied to local farmers: the import of foods from countries like Kenya decreases the money spent on small, local farms. In addition, eliminating the need to import food is beneficial to the national economy, as money is being spent on American farmers, who will then spend that money in America, rather than being spent outside of the country.\nPerhaps the most powerful appeal to the locavore diet is its healthiness. Not only do local foods have fewer susceptibility to contamination, but the physical distance of local foods causes them to harbor more powerful vitamins, minerals, and disease-fighting substances. In Source B, Smith argues that because local fruits and vegetables travel shorter distances, they are therefore more likely to be closer to maximum nutritional value. In a notoriously unhealthy society, Americans are likely to benefit from the locavore diet because it emphasizes the importance of eating fruits and vegetables.\nThe locavore diet, while having some drawbacks, is overall beneficial to small communities: it keeps local farms in business which in turn stimulates the local and national economies, it reduces potentially harmful environmental impacts by decreasing the use of air and road transportation, and it allows for more nutritional value in the foods people eat. Worldwide, the locavore diet may not be as helpful, as it would all but eliminate the need for food trade. However, for small, tight-knit communities, the locavore diet would be arguably beneficial.",

Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing. We show that our models offer competitive performance or even better that mBERT.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task.\nWe illustrate that our bilingual LMs can serve as an excellent feature extractor in supervised dependency parsing task (§5).",

        "question": "Why predicting human behavior is challenging?",
        "answer": "Predicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other.",
        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other.",

        "evidence": "Suppose a user wants to write a sentence “I will be 10 minutes late.” Ideally, she would type just a few keywords such as “10 minutes late” and an autocomplete system would be able to infer the intended sentence (Figure FIGREF1). Existing left-to-right autocomplete systems BIBREF0, BIBREF1 can often be inefficient, as the prefix of a sentence (e.g. “I will be”) fails to capture the core meaning of the sentence. Besides the practical goal of building a better autocomplete system, we are interested in exploring the tradeoffs inherent to such communication schemes between the efficiency of typing keywords, accuracy of reconstruction, and interpretability of keywords.\nOne approach to learn such schemes is to collect a supervised dataset of keywords-sentence pairs as a training set, but (i) it would be expensive to collect such data from users, and (ii) a static dataset would not capture a real user's natural predilection to adapt to the system BIBREF2. Another approach is to avoid supervision and jointly learn a user-system communication scheme to directly optimize the combination of efficiency and accuracy. However, learning in this way can lead to communication schemes that are uninterpretable to humans BIBREF3, BIBREF4 (see Appendix for additional related work).\nIn this work, we propose a simple, unsupervised approach to an autocomplete system that is efficient, accurate, and interpretable. For interpretability, we restrict keywords to be subsequences of their source sentences based on the intuition that humans can infer most of the original meaning from a few keywords. We then apply multi-objective optimization approaches to directly control and achieve desirable tradeoffs between efficiency and accuracy.\nWe observe that naively optimizing a linear combination of efficiency and accuracy terms is unstable and leads to suboptimal schemes. Thus, we propose a new objective which optimizes for communication efficiency under an accuracy constraint. We show this new objective is more stable and efficient than the linear objective at all accuracy levels.\nAs a proof-of-concept, we build an autocomplete system within this framework which allows a user to write sentences by specifying keywords. We empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences. Finally, we demonstrate that humans can easily adapt to the keyword-based autocomplete system and save nearly 50% of time compared to typing a full sentence in our user study.\nOne approach to learn such schemes is to collect a supervised dataset of keywords-sentence pairs as a training set, but (i) it would be expensive to collect such data from users, and (ii) a static dataset would not capture a real user's natural predilection to adapt to the system [34].",

        "evidence": "Designing reward functions for complex, real-world tasks is challenging. Reward learning lets one instead infer reward functions from data. However, multiple reward functions often fit the data equally well, even in the infinite-data limit. Prior work often considers reward functions to be uniquely recoverable, by imposing additional assumptions on data sources. By contrast, we formally characterise the partial identifiability of popular data sources, including demonstrations and trajectory preferences, under multiple standard sets of assumptions. We analyse the impact of this partial identifiability on downstream tasks such as policy optimisation, including under shifts in environment dynamics. We unify our results in a framework for comparing data sources and downstream tasks by their invariances, with implications for the design and selection of data sources for reward learning.\nInverse reinforcement learning (IRL; is the prototypical example of reward learning. IRL infers a reward function from the behavioural data of a task expert by inverting a model of the expert's planning algorithm. Existing work partially characterises the inherent ambiguity of behaviour for certain planning algorithms and classes of tasks. We extend these results to more planning algorithms and arbitrary time-unbounded, stochastic tasks, using a more expressive space of reward functions that reveals novel ambiguity.\nReward learning models have been proposed for many other data sources. A popular and effective data source is preferences over behavioural trajectories. Unlike for IRL, the ambiguity arising from these data sources has not been formally characterised. We contribute a formal characterisation of the ambiguity for central models of evaluative feedback including trajectory preferences.\nSeveral studies have explored learning from expert behaviour and preferences, or other multi-modal data sources. One motivation is that different data sources may provide complementary reward information, eliminating some ambiguity. Similarly, and observe reduced ambiguity by combining behavioural data across multiple tasks. Our partial order provides a general framework for understanding these results.\nComputing an optimal behavioural policy is a primary application of learnt reward functions. proved that potential shaping transformations always preserve the set of optimal policies, and so are always tolerable for this application. We extend this result, characterising the full set of transformations that preserve optimal policies in each task, including for additional policy optimisation techniques such as maximum entropy RL. Ambiguity corresponds to the partial identifiability of the reward function modelled as a latent parameter. The prevailing response to partial identifiability in reward learning has been to impose additional constraints or assumptions until the data identifies the reward function uniquely (or, at least, sufficiently for policy optimisation). Following and, we instead describe ambiguity given various constraints and assumptions. This gives practitioners results appropriate for their real data (and the ambiguity tolerance of their actual application).\nIRL is related to dynamic discrete choice, a problem where identifiability has been extensively studied (e.g.,. We study a simpler setting with known tasks. IRL also relates to preference elicitation and inverse optimal control. Preferences over sequential trajectories are not typically considered as a data source in other fields.\nSubstantial effort has been invested to develop reward learning algorithms for a variety of data sources. A fundamental question to ask is how effective are these algorithms relative to an optimal algorithm for that data source? Our results characterise the information available in different data sources, enabling algorithms to be compared to this theoretical upper bound. Moreover, our framework enables direct comparisons between different data sources. We find that some data sources are strictly less informative than others, such as noiseless preference comparisons vs. return labels. By contrast, others are incomparable and have complementary ambiguity, such as Q-values (invariant to S 1 -redistribution but not potential shaping) vs. episode return G ξ (invariant to some potential shaping, but not to S 1 -redistribution).\nIn particular, we have characterised the invariances of various reward-related objects to transformations such as potential shaping. We have shown that these objects form a partial order under ambiguity refinement. These results, summarised in figure, allow us to predict the ambiguity of data sources generated from these objects. While practitioners could simply collect data from the least ambiguous source, this might be very expensive. Our framework also identifies the ambiguity tolerance of downstream applications (such as policy optimisation) that need to compute these objects. This enables practitioners to identify reward learning data sources with low ambiguity in the areas their application is sensitive to, enabling higher performance without unnecessary costs.\nWe analyse the impact of this partial identififiability on downstream tasks such as policy optimisation, including under shifts in environment dynamics. We unify our results in a framework for comparing data sources and downstream tasks by their invariances, with implications for the design and selection of data sources for reward learning.**** We extend this result, characterising the full set of transformations that preserve optimal policies in each task, including for additional policy optimisation techniques such as maximum entropy RL.****Our framework also identifies the ambiguity tolerance of downstream applications (such as policy optimisation) that need to compute these ob jects.",

        "evidence": "In information retrieval (IR), queries and documents are typically represented by term vectors where each term is a content word and weighted by tf-idf, i.e. the product of the term frequency and the inverse document frequency, or other weighting schemes BIBREF0 . The similarity of a query and a document is then determined as a dot product or cosine similarity. Although this works reasonably, the traditional IR scheme often fails to find relevant documents when synonymous or polysemous words are used in a dataset, e.g. a document including only “neoplasm\" cannot be found when the word “cancer\" is used in a query. One solution of this problem is to use query expansion BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 or dictionaries, but these alternatives still depend on the same philosophy, i.e. queries and documents should share exactly the same words.\nWhile the term vector model computes similarities in a sparse and high-dimensional space, the semantic analysis methods such as latent semantic analysis (LSA) BIBREF5 , BIBREF6 and latent Dirichlet allocation (LDA) BIBREF7 learn dense vector representations in a low-dimensional space. These methods choose a vector embedding for each term and estimate a similarity between terms by taking an inner product of their corresponding embeddings BIBREF8 . Since the similarity is calculated in a latent (semantic) space based on context, the semantic analysis approaches do not require having common words between a query and documents. However, it has been shown that LSA and LDA methods do not produce superior results in various IR tasks BIBREF9 , BIBREF10 , BIBREF11 and the classic ranking method, BM25 BIBREF12 , usually outperforms those methods in document ranking BIBREF13 , BIBREF14 .\nNeural word embedding BIBREF15 , BIBREF16 is similar to the semantic analysis methods described above. It learns low-dimensional word vectors from text, but while LSA and LDA utilize co-occurrences of words, neural word embedding learns word vectors to predict context words BIBREF10 . Moreover, training of semantic vectors is derived from neural networks. Both co-occurrence and neural word embedding approaches have been used for lexical semantic tasks such as semantic relatedness (e.g. king and queen), synonym detection (e.g. cancer and carcinoma) and concept categorization (e.g. banana and pineapple belong to fruits) BIBREF10 , BIBREF17 . But, Baroni et al. Baroni2014 showed that neural word embedding approaches generally performed better on such tasks with less effort required for parameter optimization. The neural word embedding models have also gained popularity in recent years due to their high performance in NLP tasks BIBREF18 .\nHere we present a query-document similarity measure using a neural word embedding approach. This work is particularly motivated by the Word Mover's Distance BIBREF19 . Unlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document. Our first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets BIBREF20 , BIBREF21 , and the experimental results showed that our approach was better than BM25 ranking. This was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.\nIn general, conventional ranking models (e.g. BM25) rely on a manually designed ranking function and require heuristic optimization for parameters BIBREF22 , BIBREF23 . In the age of information explosion, this one-size-fits-all solution is no longer adequate. For instance, it is well known that links to a web page are an important source of information in web document search BIBREF24 , hence using the link information as well as the relevance between a query and a document is crucial for better ranking. In this regard, learning to rank BIBREF22 has drawn much attention as a scheme to learn how to combine diverse features. Given feature vectors of documents and their relevance levels, a learning to rank approach learns an optimal way of weighting and combining multiple features.\nWe argue that the single scores (or features) produced by BM25 and our proposed semantic measure complement each other, thus merging these two has a synergistic effect. To confirm this, we measured the impact on document ranking by combining BM25 and semantic scores using the learning to rank approach, LamdaMART BIBREF25 , BIBREF26 . Trained on PubMed user queries and their click-through data, we evaluated the search performance based on the most highly ranked 20 documents. As a result, we found that using our semantic measure further improved the performance of BM25.\nTaken together, we make the following important contributions in this work. First, to the best of our knowledge, this work represents the first investigation of query-document similarity for information retrieval using the recently proposed Word Mover's Distance. Second, we modify the original Word Mover's Distance algorithm so that it is computationally less expensive and thus more practical and scalable for real-world search scenarios (e.g. biomedical literature search). Third, we measure the actual impact of neural word embeddings in PubMed by utilizing user queries and relevance information derived from click-through data. Finally, on TREC and PubMed datasets, our proposed method achieves stronger performance than BM25.\nUnlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document.",

The goal of our crowdsourcing scheme is to obtain a score for each proposition indicating its importance in a document cluster, such that a ranking according to the score would reveal what is most important and should be included in a summary. In contrast to other work, we do not show the documents to the workers at all, but provide only a description of the document cluster's topic along with the propositions. This ensures that tasks are small, simple and can be done quickly (see Figure FIGREF4 ).\nIn preliminary tests, we found that this design, despite the minimal context, works reasonably on our focused clusters on common educational topics. For instance, consider Figure FIGREF4 : One can easily say that P1 is more important than P2 without reading the documents.\nWe distinguish two task variants:\nInstead of enforcing binary importance decisions, we use a 5-point Likert-scale to allow more fine-grained annotations. The obtained labels are translated into scores (5..1) and the average of all scores for a proposition is used as an estimate for its importance. This follows the idea that while single workers might find the task subjective, the consensus of multiple workers, represented in the average score, tends to be less subjective due to the “wisdom of the crowd”. We randomly group five propositions into a task.\nAs an alternative, we use a second task design based on pairwise comparisons. Comparisons are known to be easier to make and more consistent BIBREF32 , but also more expensive, as the number of pairs grows quadratically with the number of objects. To reduce the cost, we group five propositions into a task and ask workers to order them by importance per drag-and-drop. From the results, we derive pairwise comparisons and use TrueSkill BIBREF35 , a powerful Bayesian rank induction model BIBREF34 , to obtain importance estimates for each proposition.\nAs an alternative, we use a second task design based on pairwise comparisons.

We instruct two annotators to read the input sentence and rank the competing summaries from first to last according to their relevance and fluency: (a) the original summary gold, and from models (b) base, (c) base+E2Tcnn, and (d) base+E2Trnn. We then compute (i) the proportion of every ranking of each model and (ii) the mean rank of each model. The results are reported in Table 4 . The model with the best mean rank is base+E2Tcnn, followed by gold, then by base+E2Trnn and base, respectively. We also perform ANOVA and post-hoc Tukey tests to show that the CNN variant is significantly ( $p<0.01$ ) better than the RNN variant and the base model. The RNN variant does not perform as well as the CNN variant, contrary to the automatic ROUGE evaluation above. Interestingly, the CNN variant produces better (but with no significant difference) summaries than the gold summaries. We posit that this is due to the fact that the article title does not correspond to the summary of the first sentence.\nIn Gigaword dataset where the texts are short, our best model achieves a comparable performance with the current state-of-the-art.",

The major advantage comes from using a high optical resolution mouse to control the player’s viewpoint.  In the FPS world, this translates to targeting an opponent.  The mouse allows for extremely fine grained movement of the viewing reticle to hone in on specific areas such as the target’s head.  Hitting the head often immediately results in death for the target or significant loss of health.  Additionally, the operator has access to other keys on the keyboard for quick access to a wider range of functions which differ based on the game.

This can be seen in a prism or a rainbow, where sunlight is separated into its component colors. When all these colors are combined, the result is white light.\n\nIn terms of pigments, white can be created by using a substance that reflects all colors and absorbs none. This means that when white light hits the surface of the object, it is reflected back to the viewer as white. Titanium dioxide is a common pigment used in white paint, for example, because it is highly reflective and opaque.\n\nIn the digital world, white is often created by using RGB color values of 255, 255, 255, which means that all three primary colors (red, green, and blue) are at their maximum intensity.

        "evidence": "We now evaluate LiLi in terms of its predictive performance and strategy formulation abilities.\nData: We use two standard datasets (see Table 4): (1) Freebase FB15k, and (2) WordNet INLINEFORM0 . Using each dataset, we build a fairly large graph and use it as the original KB ( INLINEFORM1 ) for evaluation. We also augment INLINEFORM2 with inverse triples ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ) for each ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) following existing KBC methods.\nParameter Settings. Unless specified, the empirically set parameters (see Table 1) of LiLi are: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 , INLINEFORM4 , INLINEFORM5 , INLINEFORM6 , INLINEFORM7 , INLINEFORM8 , INLINEFORM9 , INLINEFORM10 . For training RL-model with INLINEFORM11 -greedy strategy, we use INLINEFORM12 , INLINEFORM13 , pre-training steps=50000. We used Keras deep learning library to implement and train the prediction model. We set batch-size as 128, max. training epoch as 150, dropout as 0.2, hidden units and embedding size as 300 and learning rate as 5e-3 which is reduced gradually on plateau with factor 0.5 and patience 5. Adam optimizer and early stopping were used in training. We also shuffle INLINEFORM14 in each epoch and adjust class weights inversely proportional to class frequencies in INLINEFORM15 .\nLabeled Dataset Generation and Simulated User Creation. We create a simulated user for each KB to evaluate LiLi. We create the labeled datasets, the simulated user’s knowledge base ( INLINEFORM0 ), and the base KB ( INLINEFORM1 ) from INLINEFORM2 . INLINEFORM3 used as the initial KB graph ( INLINEFORM4 ) of LiLi.\nWe followed BIBREF16 for labeled dataset generation. For Freebase, we found 86 relations with INLINEFORM0 triples and randomly selected 50 from various domains. We randomly shuffle the list of 50 relations, select 25% of them as unknown relations and consider the rest (75%) as known relations. For each known relation INLINEFORM1 , we randomly shuffle the list of distinct triples for INLINEFORM2 , choose 1000 triples and split them into 60% training, 10% validation and 20% test. Rest 10% along with the leftover (not included in the list of 1000) triples are added to INLINEFORM3 . For each unknown relation INLINEFORM4 , we remove all triples of INLINEFORM5 from INLINEFORM6 and add them to INLINEFORM7 . In this process, we also randomly choose 20% triples as test instances for unknown INLINEFORM8 which are excluded from INLINEFORM9 . Note that, now INLINEFORM10 has at least 10% of chosen triples for each INLINEFORM11 (known and unknown) and so, user is always able to provide clues for both cases. For each labeled dataset, we randomly choose 10% of the entities present in dataset triples, remove triples involving those entities from INLINEFORM12 and add to INLINEFORM13 . At this point, INLINEFORM14 gets reduced to INLINEFORM15 and is used as INLINEFORM16 for LiLi. The dataset stats in Table 4 shows that the base KB (60% triples of INLINEFORM17 ) is highly sparse (compared to original KB) which makes the inference task much harder. WordNet dataset being small, we select all 18 relations for evaluation and create labeled dataset, INLINEFORM18 and INLINEFORM19 following Freebase. Although the user may provide clues 100% of the time, it often cannot respond to MLQs and CLQs (due to lack of required triples/facts). Thus, we further enrich INLINEFORM20 with external KB triples.\nGiven a relation INLINEFORM0 and an observed triple ( INLINEFORM1 , INLINEFORM2 , INLINEFORM3 ) in training or testing, the pair ( INLINEFORM4 , INLINEFORM5 ) is regarded as a +ve instance for INLINEFORM6 . Following BIBREF18 , for each +ve instance ( INLINEFORM7 , INLINEFORM8 ), we generate two negative ones, one by randomly corrupting the source INLINEFORM9 , and the other by corrupting the target INLINEFORM10 . Note that, the test triples are not in INLINEFORM11 or INLINEFORM12 and none of the -ve instances overlap with the +ve ones.\nBaselines. As none of the existing KBC methods can solve the OKBC problem, we choose various versions of LiLi as baselines.\nSingle: Version of LiLi where we train a single prediction model INLINEFORM0 for all test relations.\nSep: We do not transfer (past learned) weights for initializing INLINEFORM0 , i.e., we disable LL.\nF-th): Here, we use a fixed prediction threshold 0.5 instead of relation-specific threshold INLINEFORM0 .\nBG: The missing or connecting links (when the user does not respond) are filled with “@-RelatedTo-@\" blindly, no guessing mechanism.\nw/o PTS: LiLi does not ask for additional clues via past task selection for skillset improvement.\nEvaluation Metrics. To evaluate the strategy formulation ability, we introduce a measure called Coverage( INLINEFORM0 ), defined as the fraction of total query data instances, for which LiLi has successfully formulated strategies that lead to winning. If LiLi wins on all episodes for a given dataset, INLINEFORM1 is 1.0. To evaluate the predictive performance, we use Avg. MCC and avg. +ve F1 score.\nUnless specified, the empirically set parameters (see Table 1) of LiLi are: α = 0.8, γ = 0.9, δIL = 5, δπ = 3, ηπ = 7, ηw = 20, l = 0.07, h = 0.2, k = 300, β = 0.5, ρ = 25%.",

Each sample represents the amplitude of the signal at a specific point in time, and the samples are uniformly spaced in time. The amplitude is the only information explicitly stored in the sample, and it is typically stored as either an integer or a floating point number, encoded as a binary number with a fixed number of digits: the sample's bit depth, also referred to as word length or word size.\n\nThe resolution indicates the number of discrete values that can be represented over the range of analog values. The resolution of binary integers increases exponentially as the word length increases. Adding one bit doubles the resolution, adding two quadruples it and so on. The number of possible values that can be represented by an integer bit depth can be calculated by using 2^n, where n is the bit depth. Thus, a 16-bit system has a resolution of 65,536 (2^16) possible values.",

Protestants reject the Catholic doctrine of papal supremacy, and have variant views on the number of sacraments, the real presence of Christ in the Eucharist, and matters of ecclesiastical polity and apostolic succession. Other Protestant denominations and non-denominational Protestants may be typically unconcerned about most of these theological issues and focus only on their perception of explicit Christian teachings in the Bible itself.

This information can be exploited in decision making processes but, to be useful, it should be transformed and presented in ways that make its intrinsic knowledge more readily intelligible. For that, we need efficient methods and tools that quickly extract useful information from unstructured text collections. Such demand can be observed, for instance, in Biology, where researchers, in order to be abreast of all developments, need to analyse new biomedical literature on a daily basis BIBREF2 . Another application is on fraud and corruption studies where the network information — the set of actors and their relationships — is implicitly stored in unstructured natural-language documents BIBREF3 . Hence, text mining and information extraction are required to pre-process the texts in order to extract the entities and the relations between them.\nInformation extraction is a challenging task mainly due to the ambiguous features of natural-language. Moreover, most tools need to be adapted to different human languages and to different domains BIBREF4 . In fact, the language of the processed texts is still the decisive factor when choosing among existing information extraction technologies. This is also true for the task of entity extraction (Named Entity Recognition - NER).\nFor several reasons, text mining tools are typically first developed for English and only afterwards extended to other languages. Thus, there are still relatively few text mining tools for Portuguese and even less that are freely accessible. In particular, for the named entities recognition task in Portuguese texts, we find three extractors available: Alchemy, Zemanta and Rembrandt BIBREF5 . We also find some studies where the measures ( INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ) for those extractors are computed and compared BIBREF6 , but their comparative effectiveness remains domain and final purpose dependent.\nIn this work, we present PAMPO (PAttern Matching and POs tagging based algorithm for NER), a new method to automatically extract named entities from unstructured texts, applicable to the Portuguese language but potentially adaptable to other languages as well. The method relies on flexible pattern matching, part-of-speech tagging and lexical-based rules. All steps are implemented using free software and taking advantage of various existing packages.\nThe process has been developed using as case-study a specific book written in Portuguese, but it has since been used in other applications and successfully tested in different text collections. In this paper, we describe the evaluation procedures on independent textual collections, and produce a comparative study of PAMPO with other existing tools for NER.\nIn this work, we present PAMPO (PAttern Matching and POs tagging based algorithm for NER), a new method to automatically extract named entities from unstructured texts, applicable to the Portuguese language but potentially adaptable to other languages as well.",

It was developed by statistician and sociologist Corrado Gini.\nThe Gini coefficient measures the inequality among values of a frequency distribution, such as levels of income. A Gini coefficient of 0 reflects perfect equality, where all income or wealth values are the same, while a Gini coefficient of 1 (or 100%) reflects maximal inequality among values. For example, if everyone has the same income, the Gini coefficient will be 0. In contrast, a Gini coefficient of 1 indicates that within a group of people, a single individual has all the income or consumption, while all others have none.\nThe Gini coefficient was proposed by Corrado Gini as a measure of inequality of income or wealth.  For OECD countries, in the late 20th century, considering the effect of taxes and transfer payments, the income Gini coefficient ranged between 0.24 and 0.49, with Slovenia being the lowest and Mexico the highest. African countries had the highest pre-tax Gini coefficients in 2008–2009, with South Africa having the world's highest, estimated to be 0.63 to 0.7, although this figure drops to 0.52 after social assistance is taken into account, and drops again to 0.47 after taxation.

On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs). As baselines, we compare with feature spaces comprising of char n-grams BIBREF0 , TF-IDF vectors, and Bag of Words vectors (BoWV).\nMain contributions of our paper are as follows: (1) We investigate the application of deep learning methods for the task of hate speech detection.

For her, the sand holds the promise of new textures, the opportunity to build a yet-unseen creation, and hours of delight before her. The adult sees sand and worries about dirt and bringing sand into the house. The adult has had many experiences with sand and not all of them have been positive. The adult's, vision of sand is clouded by experience.

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets.

        "evidence": "Language modeling is a probabilistic description of language phenomenon. It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nWe also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language.",

At the heart of the Transformer lie multi-head attention mechanisms: each word is represented by multiple different weighted averages of its relevant context. As suggested by recent works on interpreting attention head roles, separate attention heads may learn to look for various relationships between tokens BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9.\nThe attention distribution of each head is predicted typically using the softmax normalizing transform. As a result, all context words have non-zero attention weight. Recent work on single attention architectures suggest that using sparse normalizing transforms in attention mechanisms such as sparsemax – which can yield exactly zero probabilities for irrelevant words – may improve performance and interpretability BIBREF12, BIBREF13, BIBREF14. Qualitative analysis of attention heads BIBREF0 suggests that, depending on what phenomena they capture, heads tend to favor flatter or more peaked distributions.\nRecent works have proposed sparse Transformers BIBREF10 and adaptive span Transformers BIBREF11. However, the “sparsity\" of those models only limits the attention to a contiguous span of past tokens, while in this work we propose a highly adaptive Transformer model that is capable of attending to a sparse set of words that are not necessarily contiguous. Figure FIGREF1 shows the relationship of these methods with ours.\nOur contributions are the following:\nWe introduce sparse attention into the Transformer architecture, showing that it eases interpretability and leads to slight accuracy gains.\nWe propose an adaptive version of sparse attention, where the shape of each attention head is learnable and can vary continuously and dynamically between the dense limit case of softmax and the sparse, piecewise-linear sparsemax case.\nWe make an extensive analysis of the added interpretability of these models, identifying both crisper examples of attention head behavior observed in previous work, as well as novel behaviors unraveled thanks to the sparsity and adaptivity of our proposed model.\nWe introduce sparse attention into the Transformer architecture, showing that it eases interpretability and leads to slight accuracy gains.",

        "question": "Some people describe braising as \"transformative\". Why is this so?",
        "evidence": "",
        "answer": "Braising is a common cooking technique where some primary ingredient (typically a cut of tough meat) cooks for a long time under low temperature and with lots of liquid. The main advantage of braising is that it causes the collagen in the meat fibers to break down into gelatin, which makes the meat fibers more separated and thus the meat more tender. In addition, the gelatin mixes with the remaining cooking liquids to create a scrumptious sauce. Thus, the overall process transforms meat from tough into tender, along with a tasty sauce that can be served alongside the meat. Braising is also convenient in that the cook does not have to attend frequently to the food during the cooking process. These two reasons, namely, rendering  tough cuts of meat (which also tend to be cheaper) more tender and requiring less effort from the cook, have made braising a common cooking technique among several cultures.",

        "answer": "It is used to improve the optimization procedure for the low-resource natural language generation (NLG) task of natural language generation (NLG).",
        "evidence": "As an essential part of a task-oriented dialogue system BIBREF0 , the task of natural language generation (NLG) is to produce a natural language utterance containing the desired information given a semantic representation consisting of dialogue act types with a set of slot-value pairs. Conventional methods using hand-crafted rules often generates monotonic utterances and it requires substantial amount of human engineering work. Recently, various neural approaches BIBREF1 , BIBREF2 , BIBREF3 have been proposed to generate accurate, natural and diverse utterances. However, these methods are typically developed for particular domains. Moreover, they are often data-intensive to train. The high annotation cost prevents developers to build their own NLG component from scratch. Therefore, it is extremely useful to train a NLG model that can be generalized to other NLG domains or tasks with a reasonable amount of annotated data. This is referred to low-resource NLG task in this paper.\nRecently, some methods have been proposed for low-resource NLG tasks. Apart from the simple data augmentation trick BIBREF4 , specialized model architectures, including conditional variational auto-encoders (CVAEs, BIBREF3 , BIBREF5 , BIBREF6 ) and adversarial domain adaptation critics BIBREF5 , have been proposed to learn domain-invariant representations. Although promising results were reported, we found that datasets used by these methods are simple which tend to enumerate many slots and values in an utterance without much linguistic variations. As a consequence, over-fitting the slots and values in the low-resource target domain could even outperform those versions trained with rich source domain examples BIBREF6 . Fortunately, there is a new large-scale dialog dataset (MultiWoz, BIBREF7 ) that contains a great variety of domains and linguistic patterns that allows us to conduct extensive and meaningful experimental analysis for low-resource NLG tasks.\nIn this paper, instead of casting the problem as model-based approaches, we propose a generalized optimization-based meta-learning approach to directly enhance the optimization procedure for the low-resource NLG task. We start by arguing that a recently proposed model-agnostic meta-learning algorithm (MAML, BIBREF8 ) is a nice fit to the low-resource NLG task. Then, we proposed a generalized NLG algorithm called Meta-NLG based on MAML by viewing languages in different domains or dialog act types as separate Meta NLG tasks. Following the essence of MAML, the goal of Meta-NLG is to learn a better initialization of model parameters that facilitates fast adaptation to new low-resource NLG scenarios. As Meta-NLG is model-agnostic as long as the model can be optimized by gradient descent, we could apply it to any existing NLG models to optimize them in a way that adapt better and faster to new low-resource tasks.\nThe main contribution of this paper is two-fold:\nIn this paper, instead of casting the problem as model-based approaches, we propose a generalized optimization-based meta-learning approach to directly enhance the optimization procedure for the low-resource NLG task.",

        "answer": "Tu et al. introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences.",
        "evidence": "Recently, neural machine translation (NMT) has gained popularity in the field of machine translation. The conventional encoder-decoder NMT proposed by Cho2014 uses two recurrent neural networks (RNN): one is an encoder, which encodes a source sequence into a fixed-length vector, and the other is a decoder, which decodes the vector into a target sequence. A newly proposed attention-based NMT by DzmitryBahdana2014 can predict output words using the weights of each hidden state of the encoder by the attention mechanism, improving the adequacy of translation.\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu2016 argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated. This is due to the fact that NMT can not completely convert the information from the source sentence to the target sentence. Mi2016a and Feng2016 pointed out that NMT lacks the notion of coverage vector in phrase-based statistical machine translation (PBSMT), so unless otherwise specified, there is no way to prevent missing translations.\nAnother problem in NMT is an objective function. NMT is optimized by cross-entropy; therefore, it does not directly maximize the translation accuracy. Shen2016 pointed out that optimization by cross-entropy is not appropriate and proposed a method of optimization based on a translation accuracy score, such as expected BLEU, which led to improvement of translation accuracy. However, BLEU is an evaluation metric based on n-gram precision; therefore, repetition of some words may be present in the translation even though the BLEU score is improved.\nTo address to problem of repeating and missing words in the translation, tu2016neural introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences. In their method, after training the forward translation in a manner similar to the conventional attention-based NMT, they train a back-translation model from the hidden state of the decoder into the source sequence by a new decoder to enforce agreement between source and target sentences.\nIn order to confirm the language independence of the framework, we experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoder-reconstructor. Our experiments show that their method offers significant improvement in BLEU scores and alleviates the problem of repeating and missing words in the translation on English-Japanese translation task, though the difference is not significant on Japanese-English translation task.\nIn addition, we jointly train a model of forward translation and back-translation without pre-training, and then evaluate this model. As a result, the encoder-decoder-reconstructor can not be trained well without pre-training, so it proves that we have to train the forward translation model in a manner similar to the conventional attention-based NMT as pre-training.\nThe main contributions of this paper are as follows:\nTo address to problem of repeating and missing words in the translation, Tu et al. (2017) introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences.",

        "question": "Can you please describe the game of golf?",

        "answer": "Golf originated in Scotland in the 15th century. It is mostly regarded as an \"upper-class\" sport reserved for members of private country clubs, but has gained a lot of popularity over the last few decades. As a result, golf has become more broadly accessible to the general public, and today the sport is enjoyed by tens of millions of people around the world. \n\nIn golf, there are a total of eighteen stretches of grass, known as holes. Each hole is comprised of a tee box, where the golfer hits his or her initial shot, the fairway, and the green. Most holes also include deep grass that runs along the fairways, known as \"the rough\". For added difficulty, holes can also contain hazards like sand bunkers or bodies of water like ponds and creeks. A small circular hole is located on every green and is marked with a flag so that golfers can see it from far away. The objective is to get your golf ball from the tee box into that small hole in as few shots (known as \"strokes\") as possible. Golfers advance their ball by striking it with a golf club, and each ball strike is counted as a stroke. Golfers are allowed to use up to 14 golf clubs over the course of their round, each of which is used for different purposes, from different distances. Some clubs, like the driver, are used to hit the ball very long distances. In fact, most professional golfers are able to drive the ball over 300 yards. That's the length of three football fields! A combination of clubs called irons make up the majority of a set of golf clubs. They are are generally used to advance the ball to the green after the golfer hits his or her initial tee shot. The club face of each iron is designed with a different loft angle. Higher loft angles enable golfers to hit the ball higher in the air and shorter distances, whereas low loft angles produce lower trajectory shots that travel longer distances. The most frequently used club in the set is the putter, which is used to tap the ball from wherever it lies on the green into the hole. On average, most good golfers will putt the ball twice per hole, or approximately 36 times per round. \n\nGolf holes are designated as par 3, par 4, or par 5, depending on their length. These numbers are an indication of how many strokes it should take for a professional golfer to complete the hole. Par 3 holes are shorter, and should take a single stroke to get the ball from tee to green. Par 5 holes are longer, and should typically take three strokes to get from tee to green. Most golf courses have four par 3 holes, four par 5 holes, and ten par 4 holes, yielding an aggregate of par 72. At the end of a round of golf, players calculate their final score by aggregating their total number of strokes across all eighteen holes. Over time, the golfer's skill level is assessed by his or her \"handicap\", which is a system that reflects the average number of strokes over par that the player typically shoots. For example, if one's average round score is 79, their handicap is 7 because it's 7 strokes above par. The lower the handicap, the better the golfer.",

        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nThe frame-semantic parser is built based on FrameNet and BabelNet where FrameNet is used to capture the meaning of the sentence and BabelNet is used to disambiguate the meaning of the extracted entities from the sentence.",

We selected a subset of 1061 users among INLINEFORM0 as gold standard dataset INLINEFORM1 who disclose their age. From these 1061 users, 822 belong to depressed class and 239 belong to control class. From 3981 depressed users, 20.6% disclose their age in contrast with only 4% (239/4789) among control group. So self-disclosure of age is more prevalent among vulnerable users. Figure FIGREF18 depicts the age distribution in INLINEFORM2 . The general trend, consistent with the results in BIBREF42 , BIBREF49 , is biased toward young people. Indeed, according to Pew, 47% of Twitter users are younger than 30 years old BIBREF50 . Similar data collection procedure with comparable distribution have been used in many prior efforts BIBREF51 , BIBREF49 , BIBREF42 . We discuss our approach to mitigate the impact of the bias in Section 4.1.

        "evidence": "Word Sense Disambiguation (WSD) is a fundamental task and long-standing challenge in Natural Language Processing (NLP), which aims to find the exact sense of an ambiguous word in a particular context BIBREF0. Previous WSD approaches can be grouped into two main categories: knowledge-based and supervised methods.\nKnowledge-based WSD methods rely on lexical resources like WordNet BIBREF1 and usually exploit two kinds of lexical knowledge. The gloss, which defines a word sense meaning, is first utilized in Lesk algorithm BIBREF2 and then widely taken into account in many other approaches BIBREF3, BIBREF4. Besides, structural properties of semantic graphs are mainly used in graph-based algorithms BIBREF5, BIBREF6.\nTraditional supervised WSD methods BIBREF7, BIBREF8, BIBREF9 focus on extracting manually designed features and then train a dedicated classifier (word expert) for every target lemma.\nAlthough word expert supervised WSD methods perform better, they are less flexible than knowledge-based methods in the all-words WSD task BIBREF10. Recent neural-based methods are devoted to dealing with this problem. BIBREF11 present a supervised classifier based on Bi-LSTM, which shares parameters among all word types except the last layer. BIBREF10 convert WSD task to a sequence labeling task, thus building a unified model for all polysemous words. However, neither of them can totally beat the best word expert supervised methods.\nMore recently, BIBREF12 propose to leverage the gloss information from WordNet and model the semantic relationship between the context and gloss in an improved memory network. Similarly, BIBREF13 introduce a (hierarchical) co-attention mechanism to generate co-dependent representations for the context and gloss. Their attempts prove that incorporating gloss knowledge into supervised WSD approach is helpful, but they still have not achieved much improvement, because they may not make full use of gloss knowledge.\nIn this paper, we focus on how to better leverage gloss information in a supervised neural WSD system. Recently, the pre-trained language models, such as ELMo BIBREF14 and BERT BIBREF15, have shown their effectiveness to alleviate the effort of feature engineering. Especially, BERT has achieved excellent results in question answering (QA) and natural language inference (NLI). We construct context-gloss pairs from glosses of all possible senses (in WordNet) of the target word, thus treating WSD task as a sentence-pair classification problem. We fine-tune the pre-trained BERT model and achieve new state-of-the-art results on WSD task. In particular, our contribution is two-fold:\n1. We construct context-gloss pairs and propose three BERT-based models for WSD.\n2. We fine-tune the pre-trained BERT model, and the experimental results on several English all-words WSD benchmark datasets show that our approach significantly outperforms the state-of-the-art systems.\nWe construct context-gloss pairs from glosses of all possible senses (in WordNet) of the target word, thus treating WSD task as a sentence-pair classification problem.",

However, complex neural summarization models with thousands of parameters usually require a large amount of training data. In fact, much of the neural summarization work has been trained and tested in news domains where numerous large datasets exist. For example, the CNN/DailyMail (CNN/DM) BIBREF3, BIBREF4 and New York Times (NYT) datasets are in the magnitude of 300k and 700k documents, respectively. In contrast, in other domains such as student reflections, summarization datasets are only in the magnitude of tens or hundreds of documents (e.g., BIBREF5). We hypothesize that training complex neural abstractive summarization models in such domains will not yield good performing models, and we will indeed later show that this is the case for student reflections.\nTo improve performance in low resource domains, we explore three directions. First, we explore domain transfer for abstractive summarization.

The success of BERT can largely be associated to the notion of context-aware word embeddings, which differentiate it from common approaches such as word2vec BIBREF3 that establish a static semantic embedding. Since the introduction of BERT, the NLP community continues to be impressed by the amount of ideas produced on top of this powerful language representation model. However, despite its success, it remains unclear whether the representations produced by BERT can be utilized for tasks such as commonsense reasoning. Particularly, it is not clear whether BERT shed light on solving tasks such as the Pronoun Disambiguation Problem (PDP) and Winograd Schema Challenge (WSC). These tasks have been proposed as potential alternatives to the Turing Test, because they are formulated to be robust to statistics of word co-occurrence BIBREF4 .\nIn this paper, we show that the attention maps created by an out-of-the-box BERT can be directly exploited to resolve coreferences in long sentences. As such, they can be simply repurposed for the sake of commonsense reasoning tasks while achieving state-of-the-art results on the multiple task. On both PDP and WSC, our method outperforms previous state-of-the-art methods, without using expensive annotated knowledge bases or hand-engineered features. On a Pronoun Disambiguation dataset, PDP-60, our method achieves 68.3% accuracy, which is better than the state-of-art accuracy of 66.7%. On a WSC dataset, WSC-273, our method achieves 60.3%.

        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier.

We observe a general trend that the BAE-R and BAE-I attacks often perform comparably, while the BAE-R/I and BAE-R+I attacks are much stronger. We observe that the BERT-based classifier is more robust to the BAE and TextFooler attacks than the word-LSTM and word-CNN models which can be attributed to its large size and pre-training on a large corpus.\nThe baseline attack is often stronger than the BAE-R and BAE-I attacks for the BERT based classifier. We attribute this to the shared parameter space between the BERT-MLM and the BERT classifier before fine-tuning. The predicted tokens from BERT-MLM may not drastically change the internal representations learned by the BERT classifier, hindering their ability to adversarially affect the classifier prediction.\nEffectiveness We study the effectiveness of BAE on limiting the number of R/I operations permitted on the original text. We plot the attack performance as a function of maximum $\\%$ perturbation (ratio of number of word replacements and insertions to the length of the original text) for the TREC dataset. From Figure , we clearly observe that the BAE attacks are consistently stronger than TextFooler. The classifier models are relatively robust to perturbations up to 20$\\%$, while the effectiveness saturates at 40-50$\\%$. Surprisingly, a 50$\\%$ perturbation for the TREC dataset translates to replacing or inserting just 3-4 words, due to the short text lengths.\nQualitative Examples We present adversarial examples generated by the attacks on a sentence from the IMDB and Yelp datasets in Table . BAE produces more natural looking examples than TextFooler as tokens predicted by the BERT-MLM fit well in the sentence context. TextFooler tends to replace words with complex synonyms, which can be easily detected. Moreover, BAE's additional degree of freedom to insert tokens allows for a successful attack with fewer perturbations.\nHuman Evaluation We consider successful adversarial examples generated from the Amazon and IMDB datasets and verify their sentiment and grammatical correctness. Human evaluators annotated the sentiment and the grammar (Likert scale of 1-5) of randomly shuffled adversarial examples and original texts. From Table , BAE and TextFooler have inferior accuracies compared to the Original, showing they are not always perfect. However, BAE has much better grammar scores, suggesting more natural looking adversarial examples.\nAblation Study We analyze the benefits of R/I operations in BAE in Table . From the table, the splits $\\mathbb {A}$ and $\\mathbb {B}$ are the $\\%$ of test points which compulsorily need I and R operations respectively for a successful attack. We can observe that the split $\\mathbb {A}$ is larger than $\\mathbb {B}$ thereby indicating the importance of the I operation over R. Test points in split require both R and I operations for a successful attack. Interestingly, split is largest for Subj, which is the most robust to attack (Table ) and hence needs both R/I operations. Thus, this study gives positive insights towards the importance of having the flexibility to both replace and insert words.\nRefer to the Appendix for additional results, effectiveness graphs and details of human evaluation.\nAmazon, Yelp, IMDB are sentiment classification datasets used in recent works (Sarma et al., 2018) and MR (Pang and Lee, 2005) contains movie reviews based on sentiment polarity.",

It gathers various mathematical, statistical and image processing techniques that can be used to quantify morphological, hydrological, ecological and other aspects of a land surface. Common synonyms for geomorphometry are geomorphological analysis (after geomorphology), terrain morphometry, terrain analysis, and land surface analysis. Geomorphometrics is the discipline based on the computational measures of the geometry, topography and shape of the Earth's horizons, and their temporal change. This is a major component of geographic information systems (GIS) and other software tools for spatial analysis.\n\nIn simple terms, geomorphometry aims at extracting (land) surface parameters (morphometric, hydrological, climatic etc.) and objects (watersheds, stream networks, landforms etc.) using input digital land surface model (also known as digital elevation model, DEM) and parameterization software.[Extracted surface parameters and objects can then be used, for example, to improve mapping and modelling of soils, vegetation, land use, geomorphological and geological features and similar.\n\nWith the rapid increase of sources of DEMs today (and especially due to the Shuttle Radar Topography Mission and LIDAR-based projects), extraction of land surface parameters is becoming more and more attractive to numerous fields ranging from precision agriculture, soil-landscape modelling, climatic and hydrological applications to urban planning, education and space research. The topography of almost all Earth has been today sampled or scanned, so that DEMs are available at resolutions of 100 m or better at global scale. Land surface parameters are today successfully used for both stochastic and process-based modelling, the only remaining issue being the level of detail and vertical accuracy of the DEM.",

        "evidence": "Given the large collections of unstructured and semi-structured data available on the web, there is a crucial need to enable quick and efficient access to the knowledge content within them. Traditionally, the field of information extraction has focused on extracting such knowledge from unstructured text documents, such as job postings, scientific papers, news articles, and emails. However, the content on the web increasingly contains more varied types of data, including semi-structured web pages, tables that do not adhere to any schema, photographs, videos, and audio. Given a query by a user, the appropriate information may appear in any of these different modes, and thus there's a crucial need for methods to construct knowledge bases from different types of data, and more importantly, combine the evidence in order to extract the correct answer.\nMotivated by this goal, we introduce the task of multimodal attribute extraction. Provided contextual information about an entity, in the form of any of the modes described above, along with an attribute query, the goal is to extract the corresponding value for that attribute. While attribute extraction on the domain of text has been well-studied BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , to our knowledge this is the first time attribute extraction using a combination of multiple modes of data has been considered. This introduces additional challenges to the problem, since a multimodal attribute extractor needs to be able to return values provided any kind of evidence, whereas modern attribute extractors treat attribute extraction as a tagging problem and thus only work when attributes occur as a substring of text.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API. The collection of items is diverse and includes categories such as electronic products, jewelry, clothing, vehicles, and real estate. For each item, we provide a textual product description, collection of images, and open-schema table of attribute-value pairs (see Figure 1 for an example). The provided attribute-value pairs only provide a very weak source of supervision; where the value might appear in the context is not known, and further, it is not even guaranteed that the value can be extracted from the provided evidence. In all, there are over 4 million images and 7.6 million attribute-value pairs. By releasing such a large dataset, we hope to drive progress on this task similar to how the Penn Treebank BIBREF5 , SQuAD BIBREF6 , and Imagenet BIBREF7 have driven progress on syntactic parsing, question answering, and object recognition, respectively.\nTo asses the difficulty of the task and the dataset, we first conduct a human evaluation study using Mechanical Turk that demonstrates that all available modes of information are useful for detecting values. We also train and provide results for a variety of machine learning models on the dataset. We observe that a simple most-common value classifier, which always predicts the most-common value for a given attribute, provides a very difficult baseline for more complicated models to beat (33% accuracy). In our current experiments, we are unable to train an image-only classifier that can outperform this simple model, despite using modern neural architectures such as VGG-16 BIBREF8 and Google's Inception-v3 BIBREF9 . However, we are able to obtain significantly better performance using a text-only classifier (59% accuracy). We hope to improve and obtain more accurate models in further research.\nWe observe that a simple most-common value classifier, which always predicts the most-common value for a given attribute, provides a very difficult baseline for more complicated models to beat (33% accuracy).",

        "question": "Extract the different kinds of leavening agents mentioned in this passage. Separate them with a comma.",
        "evidence": "In the Encyclopedia of Food Microbiology, Michael Gaenzle writes: \"One of the oldest sourdough breads dates from 3700 BCE and was excavated in Switzerland, but the origin of sourdough fermentation likely relates to the origin of agriculture in the Fertile Crescent and Egypt several thousand years earlier\", which was confirmed a few years later by archeological evidence. ... \"Bread production relied on the use of sourdough as a leavening agent for most of human history; the use of baker's yeast as a leavening agent dates back less than 150 years.\"\n\nSourdough remained the usual form of leavening down into the European Middle Ages until being replaced by barm from the beer brewing process, and after 1871 by purpose-cultured yeast.\n\nBread made from 100% rye flour, popular in the northern half of Europe, is usually leavened with sourdough. Baker's yeast is not useful as a leavening agent for rye bread, as rye does not contain enough gluten. The structure of rye bread is based primarily on the starch in the flour as well as other carbohydrates known as pentosans; however, rye amylase is active at substantially higher temperatures than wheat amylase, causing the structure of the bread to disintegrate as the starches are broken down during baking. The lowered pH of a sourdough starter, therefore, inactivates the amylases when heat cannot, allowing the carbohydrates in the bread to gel and set properly. In the southern part of Europe, where panettone is still made with sourdough as leavening, sourdough has become less common in the 20th century; it has been replaced by the faster-growing baker's yeast, sometimes supplemented with longer fermentation rests to allow for some bacterial activity to build flavor. Sourdough fermentation re-emerged as a major fermentation process in bread production during the 2010s, although it is commonly used in conjunction with baker's yeast as leavening agent.\n\nFrench bakers brought sourdough techniques to Northern California during the California Gold Rush, and it remains a part of the culture of San Francisco today. (The nickname remains in \"Sourdough Sam\", the mascot of the San Francisco 49ers.) Sourdough has long been associated with the 1849 gold prospectors, though they were more likely to make bread with commercial yeast or baking soda. The \"celebrated\" San Francisco sourdough is a white bread characterized by a pronounced sourness, and indeed the strain of Lactobacillus in sourdough starters is named Fructilactobacillus sanfranciscensis (previously Lactobacillus sanfranciscensis), alongside the sourdough yeast Kasachstania humilis (previously Candida milleri) found in the same cultures.\n\nThe sourdough tradition was carried into Department of Alaska in the United States and the Yukon territory in Canada during the Klondike Gold Rush of 1898. Conventional leavenings such as yeast and baking soda were much less reliable in the conditions faced by the prospectors. Experienced miners and other settlers frequently carried a pouch of starter either around their neck or on a belt; these were fiercely guarded to keep from freezing. However, freezing does not kill a sourdough starter; excessive heat does. Old hands came to be called \"sourdoughs\", a term that is still applied to any Alaskan or Klondike old-timer. The significance of the nickname's association with Yukon culture was immortalized in the writings of Robert Service, particularly his collection of \"Songs of a Sourdough\".[citation needed]\n\nIn English-speaking countries, where wheat-based breads predominate, sourdough is no longer the standard method for bread leavening. It was gradually replaced, first by the use of barm from beer making, then, after the confirmation of germ theory by Louis Pasteur, by cultured yeasts. Although sourdough bread was superseded in commercial bakeries in the 20th century, it has undergone a revival among artisan bakers and, more recently, in industrial bakeries. In countries where there is no legal definition of sourdough bread, the dough for some products named or marketed as such is leavened using baker's yeast or chemical raising agents as well as, or instead of, a live sourdough starter culture. The Real Bread Campaign calls these products sourfaux.\n\nManufacturers of non-sourdough breads make up for the lack of yeast and bacterial culture by introducing into their dough an artificially-made mix known as bread improver or flour improver.",

Some people argue that we can model languages at the character-level BIBREF1 . For alphabetic languages such as English, where the characters are much fewer than the words, the character embeddings achieved the state-of-the-art results with much fewer parameters.\nUnfortunately, for the other languages that use non-alphabetic systems, the character vocabulary can be also large. Moreover, Chinese and Japanese, two of the most widely used non-alphabetic languages, especially contain large numbers of ideographs: hanzi of Chinese and kanji of Japanese. The character vocabulary can be as scalable as the word vocabulary (e.g., see the datasets introduced in Section SECREF11 ). Hence the conventional character embedding-based method is not able to give us a slim vocabulary on Chinese and Japanese.\nFor convenience, let us collectively call hanzi and kanji as Chinese characters. Chinese characters are ideographs composed with semantic and phonetic radicals, both of which are available for character recognition, and the semantic information may be embedded in Chinese characters by the semantic radicals BIBREF2 . Besides, though the character vocabulary is huge, the number of the radicals is much fewer. Accordingly, we explored a model that represents the Chinese characters by the sequence of the radicals.

        "evidence": "Our work is motivated by three major threads of research in machine learning and natural language processing: semantic-parsing for open-domain question answering, character-level language modeling, and encoder-decoder methods.\nSemantic parsing for open-domain question answering, which translates a question into a structured KB query, is a key component in question answering with a KB. While early approaches relied on building high-quality lexicons for domain-specific databases such as GeoQuery BIBREF7 , recent work has focused on building semantic parsing frameworks for general knowledge bases such as Freebase BIBREF1 , BIBREF8 , BIBREF0 , BIBREF9 , BIBREF2 .\nSemantic parsing frameworks for large-scale knowledge bases have to be able to successfully generate queries for the millions of entities and thousands of predicates in the KB, many of which are unseen during training. To address this issue, recent work relies on producing embeddings for predicates and entities in a KB based on their textual descriptions BIBREF8 , BIBREF0 , BIBREF1 , BIBREF10 . A general interaction function can then be used to measure the semantic relevance of these embedded KB entries to the question and determine the most likely KB query.\nMost of these approaches use word-level embeddings to encode entities and predicates, and therefore might suffer from the out-of-vocabulary (OOV) problem when they encounter unseen words during test time. Consequently, they often rely on significant data augmentation from sources such as Paralex BIBREF2 , which contains 18 million question-paraphrase pairs scraped from WikiAnswers, to have sufficient examples for each word they encounter BIBREF11 , BIBREF1 , BIBREF0 .\nAs opposed to word-level modeling, character-level modeling can be used to handle the OOV issue. While character-level modeling has not been applied to factoid question answering before, it has been successfully applied to information retrieval, machine translation, sentiment analysis, classification, and named entity recognition BIBREF12 , BIBREF13 , BIBREF6 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 , BIBREF18 , BIBREF19 . Moreover, gflstm demonstrate that gated-feedback LSTMs on top of character-level embeddings can capture long-term dependencies in language modeling.\nLastly, encoder-decoder networks have been applied to many structured machine learning tasks. First introduced in sutskever2014sequence, in an encoder-decoder network, a source sequence is first encoded with a recurrent neural network (RNN) into a fixed-length vector which intuitively captures its meaning, and then decoded into a desired target sequence. This approach and related memory-based or attention-based approaches have been successfully applied in diverse domains such as speech recognition, machine translation, image captioning, parsing, executing programs, and conversational dialogues BIBREF20 , BIBREF21 , BIBREF22 , BIBREF23 , BIBREF24 , BIBREF25 , BIBREF26 .\nUnlike previous work, we formulate question answering as a problem of decoding the KB query given the question and KB entries which are encoded in embedding spaces.

Sentence representation is a challenging task that has to consider aspects such as compositionality, phrase similarity, negation, etc. In order to evaluate sentence representations, intermediate tasks such as Semantic Textual Similarity (STS) BIBREF1 or Natural Language Inference (NLI) BIBREF2 have been proposed, with STS being popular among unsupervised approaches. Through a set of campaigns, STS has produced several manually annotated datasets, where annotators measure the similarity among sentences, with higher scores for more similar sentences, ranging between 0 (no similarity) to 5 (semantic equivalence). Human annotators exhibit high inter-tagger correlation in this task.\nIn another strand of related work, tasks that combine representations of multiple modalities have gained increasing attention, including image-caption retrieval, video and text alignment, caption generation, and visual question answering. A common approach is to learn image and text embeddings that share the same space so that sentence vectors are close to the representation of the images they describe BIBREF3 , BIBREF4 .

Joint spaces are typically learned combining various types of deep learning networks such us recurrent networks or convolutional networks, with some attention mechanism BIBREF6 , BIBREF7 , BIBREF8 .\nThe complementarity of visual and text representations for improved language understanding have been shown also on word representations, where embeddings have been combined with visual or perceptual input to produce grounded representations of words BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 .

        "question": "How to perform the selection of subsets of RDF?",
        "answer": "Commonly, the selection of subsets of RDF is performed using the SPARQL query language.",
        "evidence": "Commonly, the selection of subsets of RDF is performed using the SPARQL query language. SPARQL can be used to express queries across diverse data sources. Query forms contain variables that appear in a solution result. They can be used to select all or a subset of the variables bound in a pattern match. They exist in four different instantiations, i.e., SELECT, CONSTRUCT, ASK and DESCRIBE. The SELECT query form is the most commonly used and is used to return rows of variable bindings. Therefore, we use this type of query in our explanation. CONSTRUCT allows to create a new RDF graph or modify the existing one through substituting variables in a graph templates for each solution. ASK returns a Boolean value indicating whether the graph contains a match or not. Finally, DESCRIBE is used to return all triples about the resources matching the query. For example, represents the following query “Return all scientists who were born in Ulm”.\n\n\nA SPARQL SELECT query can be regarded as consisting of three parts: (1) a body section B, which describes all data that has to be retrieved, (2) an optional section O, which describes the data items that can be retrieved by the query if they exist, and (3) a modifier section M, which describes all solution sequences, modifiers and aggregates that are to be applied to the result of the previous two sections of the query. Let Var be the set of all variables that can be used in a SPARQL query. In addition, let $R$ be the set of all resources, $P$ the set of all properties and $L$ the set of all literals contained in the target knowledge base of the SPARQL queries at hand. We call $x \\in \\text{\\em Var}\\, \\cup R \\cup P \\cup L$ an atom. The basic components of the body of a SPARQL query are triple patterns $(\\texttt {s}, \\texttt {p}, \\texttt {o}) \\in (\\text{\\em Var}\\, \\cup R) \\times (\\text{\\em Var}\\, \\cup P) \\times (\\text{\\em Var}\\, \\cup R \\cup L)$. Let $W$ be the set of all words in the dictionary of our target language. We define the realization function $\\rho : \\text{\\em Var}\\, \\cup R \\cup P \\cup L \\rightarrow W^*$ as the function which maps each atom to a word or sequence of words from the dictionary. The extension of $\\rho $ to all SPARQL constructs maps all atoms $x$ to their realization $\\rho (x)$ and defines how these atomic realizations are to be combined. We denote the extension of $\\rho $ by the same label $\\rho $ for the sake of simplicity. We adopt a rule-based approach to achieve this goal, where the rules extending $\\rho $ to all valid SPARQL constructs are expressed in a conjunctive manner. This means that for premises $P_1,\\ldots ,P_n$ and consequences $K_1,\\ldots ,K_m$ we write $P_1 \\wedge \\ldots \\wedge P_n \\Rightarrow K_1 \\wedge \\ldots \\wedge K_m$. The premises and consequences are explicated by using an extension of the Stanford dependencies.\nFor example, a possessive dependency between two phrase elements $e_1$ and $e_2$ is represented as $\\texttt {poss}(e_1,e_2)$. For the sake of simplicity, we slightly deviate from the Stanford vocabulary by not treating the copula to be as an auxiliary, but denoting it as BE. Moreover, we extend the vocabulary by the constructs conj and disj which denote the conjunction resp. disjunction of two phrase elements. In addition, we sometimes reduce the construct $\\texttt {subj(y,x)}\\wedge \\texttt {dobj(y,z)}$ to the triple (x,y,z) $\\in W^3$.\nCommonly, the selection of subsets of RDF is performed using the SPARQL query language.",

        "evidence": "",
        "answer": "A mitochondrion is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857  in the voluntary muscles of insects. The term mitochondrion was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the \"powerhouse of the cell\", a phrase coined by Philip Siekevitz in a 1957 article of the same name.\n\nSome cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A large number of unicellular organisms, such as microsporidia, parabasalids and diplomonads, have reduced or transformed their mitochondria into other structures. One eukaryote, Monocercomonoides, is known to have completely lost its mitochondria, and one multicellular organism, Henneguya salminicola, is known to have retained mitochondrion-related organelles in association with a complete loss of their mitochondrial genome.\n\nMitochondria are commonly between 0.75 and 3 μm2 in cross section, but vary considerably in size and structure. Unless specifically stained, they are not visible. In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth. Mitochondrial biogenesis is in turn temporally coordinated with these cellular processes. Mitochondria have been implicated in several human disorders and conditions, such as mitochondrial diseases, cardiac dysfunction, heart failure and autism.\n\nThe number of mitochondria in a cell can vary widely by organism, tissue, and cell type. A mature red blood cell has no mitochondria, whereas a liver cell can have more than 2000. The mitochondrion is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, intermembrane space, inner membrane, cristae, and matrix.\n\nAlthough most of a eukaryotic cell's DNA is contained in the cell nucleus, the mitochondrion has its own genome (\"mitogenome\") that is substantially similar to bacterial genomes. This finding has led to general acceptance of the endosymbiotic hypothesis - that free-living prokaryotic ancestors of modern mitochondria permanently fused with eukaryotic cells in the distant past, evolving such that modern animals, plants, fungi, and other eukaryotes are able to respire to generate cellular energy.",

        "question": "What approach does the paper propose?",
        "answer": "A human-AI loop approach for discovering informative keywords and estimating their expectations reliably.",
        "evidence": "Event detection on microblogging platforms such as Twitter aims to detect events preemptively. A main task in event detection is detecting events of predetermined types BIBREF0, such as concerts or controversial events based on microposts matching specific event descriptions. This task has extensive applications ranging from cyber security BIBREF1, BIBREF2 to political elections BIBREF3 or public health BIBREF4, BIBREF5. Due to the high ambiguity and inconsistency of the terms used in microposts, event detection is generally performed though statistical machine learning models, which require a labeled dataset for model training. Data labeling is, however, a long, laborious, and usually costly process. For the case of micropost classification, though positive labels can be collected (e.g., using specific hashtags, or event-related date-time information), there is no straightforward way to generate negative labels useful for model training. To tackle this lack of negative labels and the significant manual efforts in data labeling, BIBREF1 (BIBREF1, BIBREF3) introduced a weak supervision based learning approach, which uses only positively labeled data, accompanied by unlabeled examples by filtering microposts that contain a certain keyword indicative of the event type under consideration (e.g., `hack' for cyber security). Another key technique in this context is expectation regularization BIBREF6, BIBREF7, BIBREF1. Here, the estimated proportion of relevant microposts in an unlabeled dataset containing a keyword is given as a keyword-specific expectation. This expectation is used in the regularization term of the model's objective function to constrain the posterior distribution of the model predictions. By doing so, the model is trained with an expectation on its prediction for microposts that contain the keyword. Such a method, however, suffers from two key problems:\nDue to the unpredictability of event occurrences and the constantly changing dynamics of users' posting frequency BIBREF8, estimating the expectation associated with a keyword is a challenging task, even for domain experts;\nThe performance of the event detection model is constrained by the informativeness of the keyword used for model training. As of now, we lack a principled method for discovering new keywords and improve the model performance.\nTo address the above issues, we advocate a human-AI loop approach for discovering informative keywords and estimating their expectations reliably. Our approach iteratively leverages 1) crowd workers for estimating keyword-specific expectations, and 2) the disagreement between the model and the crowd for discovering new informative keywords. More specifically, at each iteration after we obtain a keyword-specific expectation from the crowd, we train the model using expectation regularization and select those keyword-related microposts for which the model's prediction disagrees the most with the crowd's expectation; such microposts are then presented to the crowd to identify new keywords that best explain the disagreement. By doing so, our approach identifies new keywords which convey more relevant information with respect to existing ones, thus effectively boosting model performance. By exploiting the disagreement between the model and the crowd, our approach can make efficient use of the crowd, which is of critical importance in a human-in-the-loop context BIBREF9, BIBREF10. An additional advantage of our approach is that by obtaining new keywords that improve model performance over time, we are able to gain insight into how the model learns for specific event detection tasks. Such an advantage is particularly useful for event detection using complex models, e.g., deep neural networks, which are intrinsically hard to understand BIBREF11, BIBREF12. An additional challenge in involving crowd workers is that their contributions are not fully reliable BIBREF13. In the crowdsourcing literature, this problem is usually tackled with probabilistic latent variable models BIBREF14, BIBREF15, BIBREF16, which are used to perform truth inference by aggregating a redundant set of crowd contributions. Our human-AI loop approach improves the inference of keyword expectation by aggregating contributions not only from the crowd but also from the model. This, however, comes with its own challenge as the model's predictions are further dependent on the results of expectation inference, which is used for model training. To address this problem, we introduce a unified probabilistic model that seamlessly integrates expectation inference and model training, thereby allowing the former to benefit from the latter while resolving the inter-dependency between the two.\nTo the best of our knowledge, we are the first to propose a human-AI loop approach that iteratively improves machine learning models for event detection. In summary, our work makes the following key contributions:\nA novel human-AI loop approach for micropost event detection that jointly discovers informative keywords and estimates their expectation;\nA unified probabilistic model that infers keyword expectation and simultaneously performs model training;\nAn extensive empirical evaluation of our approach on multiple real-world datasets demonstrating that our approach significantly improves the state of the art by an average of 24.3% AUC.\nThe rest of this paper is organized as follows. First, we present our human-AI loop approach in Section SECREF2. Subsequently, we introduce our proposed probabilistic model in Section SECREF3. The experimental setup and results are presented in Section SECREF4. Finally, we briefly cover related work in Section SECREF5 before concluding our work in Section SECREF6.\nTo address the above issues, we advocate a human-AI loop approach for discovering informative keywords and estimating their expectations reliably.",

Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

Given the information overload on the web, manual monitoring for cyberbullying has become unfeasible. Automatic detection of signals of cyberbullying would enhance moderation and allow to respond quickly when necessary.\nCyberbullying research has often focused on detecting cyberbullying `attacks', hence overlooking posts written by victims and bystanders. However, these posts could just as well indicate that cyberbullying is going on. The main contribution of this paper is that it presents a system for detecting signals of cyberbullying on social media, including posts from bullies, victims and bystanders. A manually annotated cyberbullying dataset was created for two languages, which will be made available for public scientific use. Moreover, while a fair amount of research has been done on cyberbullying detection for English, we believe this is one of the first papers that focus on Dutch as well.\nA set of binary classification experiments were conducted to explore the feasibility of automatic cyberbullying detection on social media. In addition, we sought to determine which information sources contribute to this task. Two classifiers were trained on English and Dutch ASKfm data and evaluated on a holdout test of the same genre. Our experiments reveal that the current approach is a promising strategy for detecting signals of cyberbullying in social media data automatically. After feature selection and hyperparameter optimisation, the classifiers achieved an F INLINEFORM0 -score of 64.32% and 58.72% for English and Dutch, respectively. The systems hereby significantly outperformed a keyword and an (unoptimised) INLINEFORM1 -gram baseline. Analysis of the results revealed that false positives often include implicit cyberbullying or offenses through irony, the challenge of which will constitute an important area for future work.\nAnother interesting direction for future work would be the detection of fine-grained cyberbullying-related categories such as threats, curses and expressions of racism and hate. When applied in a cascaded model, the system could find severe cases of cyberbullying with high precision. This would be particularly interesting for monitoring purposes, since it would allow to prioritise signals of bullying that are in urgent need for manual inspection and follow-up.\nFinally, future work will focus on the detection of participants (or roles) typically involved in cyberbullying. This would allow to analyse the context of a cyberbullying incident and hence evaluate its severity. When applied as moderation support on online platforms, such a system would allow to provide feedback in function of the recipient (i.e., a bully, victim, or bystander).\nWhen applied in a cascaded model, the system could find severe cases of cyberbullying with high precision.",

        "question": "What makes it hard to hard task for the task?",
        "answer": "The diversity of language makes it hard.",
        "evidence": "It is common knowledge in modern NLP that using large amounts of high-quality training data is a key aspect in building successful machine-learning based systems. For this reason, a major challenge when building such systems is obtaining data in the domain of interest. But what defines a domain? Natural language varies greatly across topics, styles, levels of formality, genres and many other linguistic nuances BIBREF0, BIBREF1, BIBREF2. This overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impossible to well-define the exact requirements from such data with respect to all the aforementioned aspects. On top of that, domain labels are usually unavailable – e.g. in large-scale web-crawled data like Common Crawl which was recently used to train state-of-the-art pretrained language models for various tasks BIBREF3.\nDomain data selection is the task of selecting the most appropriate data for a domain from a large corpus given a smaller set of in-domain data BIBREF4, BIBREF5, BIBREF6, BIBREF7. In this work, we propose to use the recent, highly successful self-supervised pre-trained language models, e.g. devlin-etal-2019-bert,liu2019roberta for domain data selection. As pretrained LMs demonstrate state-of-the-art performance across many NLP tasks after being trained on massive amounts of data, we hypothesize that the robust representations they learn can be useful for mapping sentences to domains in an unsupervised, data-driven approach. We show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering. We then propose methods to leverage these emergent domain clusters for domain data selection in two ways:\nVia distance-based retrieval in the sentence embedding space induced by the pretrained language model.\nBy fine-tuning the pretrained language model for binary classification, where positive examples are from the domain of interest.\nOur methods enable to select relevant data for the task while requiring only a small set of monolingual in-domain data. As they are based solely on the representations learned by self-supervised LMs, they do not require additional domain labels which are usually vague and over-simplify the notion of domain in textual data. We evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8. Our data selection methods enable to train NMT models that outperform those trained using the well-established cross-entropy difference method of BIBREF4 across five diverse domains, achieving a recall of more than 95% in all cases with respect to an oracle that selects the “true” in-domain data.\nOur contributions in this work are as follows. First, we show that pre-trained language models are highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner. Second, we propose methods to select in-domain data based on this property using vector-space retrieval and positive-unlabeled fine-tuning of pretrained language models for binary classification. Third, we show the applicability of our proposed data selection methods on a popular benchmark for domain adaptation in machine translation. An additional contribution is a new, improved data split we create for this benchmark, as we point on issues with previous splits used in the literature. The code and data for this work is publicly available. We hope this work will encourage more research on understanding the data landscape in NLP, enabling to “find the right data for the task” in the age of massive models and diverse data sources.\nThis overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impos_x0002_sible to well-define the exact requirements from such data with respect to all the aforementioned aspects.",

        "question": "How do they assign answer (dis)agreement labels?",
        "answer": "When there is an exact string match for 9 of the 10 crowdsourced answers, the visual question is assigned an answer agreement label, or it is assigned an answer disagreement label.",
        "evidence": "We pose the prediction task as a binary classification problem. Specifically, given an image and associated question, a system outputs a binary label indicating whether a crowd will agree on the same answer. Our goal is to design a system that can detect which visual questions to assign a disagreement label, regardless of the disagreement cause (e.g., subjectivity, ambiguity, difficulty). We implement both random forest and deep learning classifiers.\nA visual question is assigned either an answer agreement or disagreement label. To assign labels, we employ 10 crowdsourced answers for each visual question. A visual question is assigned an answer agreement label when there is an exact string match for 9 of the 10 crowdsourced answers (after answer pre-preprocessing, as discussed in the previous section) and an answer disagreement label otherwise. Our rationale is to permit the possibility of up to one “careless/spam\" answer per visual question. The outcome of our labeling scheme is that a disagreement label is agnostic to the specific cause of disagreement and rather represents the many causes (described above).\nFor our first system, we use domain knowledge to guide the learning process. We compile a set of features that we hypothesize inform whether a crowd will arrive at an undisputed, single answer. Then we apply a machine learning tool to reveal the significance of each feature. We propose features based on the observation that answer agreement often arises when 1) a lay person's attention can be easily concentrated to a single, undisputed region in an image and 2) a lay person would find the requested task easy to address.\nWe employ five image-based features coming from the salient object subitizing BIBREF22 (SOS) method, which produces five probabilities that indicate whether an image contains 0, 1, 2, 3, or 4+ salient objects. Intuitively, the number of salient objects shows how many regions in an image are competing for an observer's attention, and so may correlate with the ease in identifying a region of interest. Moreover, we hypothesize this feature will capture our observation from the previous study that counting problems typically leads to disagreement for images showing many objects, and agreement otherwise.\nWe employ a 2,492-dimensional feature vector to represent the question-based features. One feature is the number of words in the question. Intuitively, a longer question offers more information and we hypothesize additional information makes a question more precise. The remaining features come from two one-hot vectors describing each of the first two words in the question. Each one-hot vector is created using the learned vocabularies that define all possible words at the first and second word location of a question respectively (using training data, as described in the next section). Intuitively, early words in a question inform the type of answers that might be possible and, in turn, possible reasons/frequency for answer disagreement. For example, we expect “why is\" to regularly elicit many opinions and so disagreement. This intuition about the beginning words of a question is also supported by our analysis in the previous section which shows that different answer types yield different biases of eliciting answer agreement versus disagreement.\nWe leverage a random forest classification model BIBREF23 to predict an answer (dis)agreement label for a given visual question. This model consists of an ensemble of decision tree classifiers. We train the system to learn the unique weighted combinations of the aforementioned 2,497 features that each decision tree applies to make a prediction. At test time, given a novel visual question, the trained system converts a 2,497 feature descriptor of the visual question into a final prediction that reflects the majority vote prediction from the ensemble of decision trees. The system returns the final prediction along with a probability indicating the system's confidence in that prediction. We employ the Matlab implementation of random forests, using 25 trees and the default parameters.\nWe next adapt a VQA deep learning architecture BIBREF24 to learn the predictive combination of visual and textual features. The question is encoded with a 1024-dimensional LSTM model that takes in a one-hot descriptor of each word in the question. The image is described with the 4096-dimensional output from the last fully connected layer of the Convolutional Neural Network (CNN), VGG16 BIBREF25 . The system performs an element-wise multiplication of the image and question features, after linearly transforming the image descriptor to 1024 dimensions. The final layer of the architecture is a softmax layer.\nWe train the system to predict (dis)agreement labels with training examples, where each example includes an image and question. At test time, given a novel visual question, the system outputs an unnormalized log probability indicating its belief in both the agreement and disagreement label. For our system's prediction, we convert the belief in the disagreement label into a normalized probability. Consequently, predicted values range from 0 to 1 with lower values reflecting greater likelihood for crowd agreement.\nAnswer (Dis)Agreement Labels: A visual question is assigned either an answer agreement or disagreement label. To assign labels, we employ 10 crowdsourced answers for each visual question. A visual question is assigned an answer agreement label when there is an exact string match for 9 of the 10 crowdsourced answers (after answer pre-preprocessing, as discussed in the previous section) and an answer disagreement label otherwise.",

However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the Sun to the observer's eye.\n\nIn a primary rainbow, the arc shows red on the outer part and violet on the inner side.

        "evidence": "In recent years, there has been an increasing interest in Machine reading comprehension (MRC), which plays a vital role in the assessment of how well a machine could understand natural language. Several datasets BIBREF0 , BIBREF1 , BIBREF2 for machine reading comprehension have been released in recent years and have driven the evolution of powerful neural models. However, much of the research up to now has been dominated by answering questions that can be well solved solved using superficial information, yet struggles to do accurate natural language understanding and reasoning. For example, BIBREF3 jia2017Adversarial show that existing machine learning systems for MRC perform poorly under adversarial evaluation. Recent developments in MRC datasets BIBREF4 , BIBREF5 , BIBREF6 have heightened the need for deep understanding.\nKnowledge has a pivotal role in accurately understanding and reasoning natural language in MRC. Previous research BIBREF7 , BIBREF8 has established that human reading comprehension requires both words and world knowledge. In this paper, we consider words and world knowledge in the format of triplets (subject, predicate, object). Specifically, we believe the advantages of using knowledge in MRC are three-fold. First, utilizing knowledge in MRC supports reasoning over multiple triplets because a single triplet may not cover the entire question. Multi-hop reasoning is also a long-standing goal in question answering. Second, building a question answering system based on triplet-style knowledge facilitates the interpretability of the decision making process. Triplets organize the document together with KBs as a graph, where a well-designed model such as PCNet, which we will describe in a later section, expressly reveal rationales for their predictions. Third, representing the documents as knowledge allows for ease of accessing and leveraging the knowledge from external/background knowledge because the knowledge representation of a document is easily consistent with both manually curated and automatically extracted KBs.\nIn this paper, we present knowledge based machine reading comprehension, which requires reasoning over triplet-style knowledge involved in a document. However, we find published dataset do not sufficiently support this task. We conduct preliminary exploration on SQuAD BIBREF0 . We use a strong open IE algorithm BIBREF9 to extract triplets from the documents and observe that only 15% of instances have an answer that is exactly the same as the corresponding subject/object in the extracted triplets. To do knowledge-based MRC, We build a new dataset consisting of 40,047 examples for the knowledge based MRC task. The annotation of this dataset is designed so that successfully answering the questions requires understanding and the knowledge involved in a document. Each instance is composed of a question, a set of triplets derived from a document, and the answer.\nWe implement a framework consisting of both a question answering model and a question generation model, both of which take the knowledge extracted from the document as well as relevant facts from an external knowledge base such as Freebase/ProBase/Reverb/NELL. The question answering model gives each candidate answer a score by measuring the semantic relevance between representation and the candidate answer representation in vector space. The question generation model provides each candidate answer with a score by measuring semantic relevance between the question and the generated question based on the semantics of the candidate answer. We implement an MRC model BiDAF BIBREF10 as a baseline for the proposed dataset. To test the scalability of our approach in leveraging external KBs, we use both manually created and automatically extracted KBs, including Freebase BIBREF11 , ProBase BIBREF12 , NELL BIBREF13 and Reverb BIBREF14 . Experiments show that incorporating evidence from external KBs improves both the matching-based and question generation-based approaches. Qualitative analysis shows the advantages and limitations of our approaches, as well as the remaining challenges.\nIn this paper, we present knowledge based machine reading comprehension, which requires reasoning over tripletstyle knowledge involved in a document. However, we find published dataset do not sufficiently support this task.**** To do knowledge-based MRC, We build a new dataset consisting of 40,047 examples for the knowledge based MRC task.",

A common definition treats a domain as a data source: “a domain is defined by a corpus from a specific source, and may differ from other domains in topic, genre, style, level of formality, etc.” BIBREF8.

        "answer": "Their goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on.",
        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nOur goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on.",

The result is comparable to the William Gray Purcell House and the Edward L. Powers House, both in Minneapolis. The horizontal lines of the Prairie School are more pronounced in this house; they are expressed in the bands of art glass windows on both levels and the cantilevered second story. Its owner, E.S.

The second story of the house is cantilevered over the first story. The entrance opens into a hallway that leads to a library on the left and a living room on the right. The living room, dining room, and an enclosed porch are all stretched across the front of the house and provide plenty of light through the art glass windows. Several of these windows provide panoramic views of the Mississippi River. The kitchen is located behind the dining room, although it has been remodeled since its original design.

        "evidence": "Machine translation finds use in cheminformatics in “translation\" from one language (e.g. reactants) to another (e.g. products). Machine translation is a challenging task because the syntactic and semantic dependencies of each language differ from one another and this may give rise to ambiguities. Neural Machine Translation (NMT) models benefit from the potential of deep learning architectures to build a statistical model that aims to find the most probable target sequence for an input sequence by learning from a corpus of examples BIBREF110, BIBREF111. The main advantage of NMT models is that they provide an end-to-end system that utilizes a single neural network to convert the source sequence into the target sequence. BIBREF110 refer to their model as a sequence-to-sequence (seq2seq) system that addresses a major limitation of DNNs that can only work with fixed-dimensionality information as input and output. However, in the machine translation task, the length of the input sequences is not fixed, and the length of the output sequences is not known in advance.\nThe variational Auto-encoder (VAE) is another widely adopted text generation architecture BIBREF101. BIBREF34 adopted this architecture for molecule generation. A traditional auto-encoder encodes the input into the latent space, which is then decoded to reconstruct the input. VAE differs from AE by explicitly defining a probability distribution on the latent space to generate new samples. BIBREF34 hypothesized that the variational part of the system integrates noise to the encoder, so that the decoder can be more robust to the large diversity of molecules. However, the authors also reported that the non-context free property of SMILES caused by matching ring numbers and parentheses might often lead the decoder to generate invalid SMILES strings. A grammar variational auto-encoder (GVAE), where the grammar for SMILES is explicitly defined instead of the auto-encoder learning the grammar itself, was proposed to address this issue BIBREF102. This way, the generation is based on the pre-defined grammar rules and the decoding process generates grammar production rules that should also be grammatically valid. Although syntactic validity would be ensured, the molecules may not have semantic validity (chemical validity). BIBREF103 built upon the VAE BIBREF34 and GVAE BIBREF102 architectures and introduced a syntax-directed variational autoencoder (SD-VAE) model for the molecular generation task. The syntax-direct generative mechanism in the decoder contributed to creating both syntactically and semantically valid SMILES sequences. BIBREF103 compared the latent representations of molecules generated by VAE, GVAE, and SD-VAE, and showed that SD-VAE provided better discriminative features for druglikeness. BIBREF104 proposed an adversarial AE for the same task. Conditional VAEs BIBREF105, BIBREF106 were trained to generate molecules conditioned on a desired property. The challenges that SMILES syntax presents inspired the introduction of new syntax such as DeepSMILES BIBREF29 and SELFIES BIBREF32 (details in Section SECREF3).\nGenerative Adversarial Network (GAN) models generate novel molecules by using two components: the generator network generates novel molecules, and the discriminator network aims to distinguish between the generated molecules and real molecules BIBREF107. In text generation models, the novel molecules are drawn from a distribution, which are then fine-tuned to obtain specific features, whereas adversarial learning utilizes generator and discriminator networks to produce novel molecules BIBREF107, BIBREF108. ORGAN BIBREF108, a molecular generation methodology, was built upon a sequence generative adversarial network (SeqGAN) from NLP BIBREF109.

An in depth survey of algorithms, features, datasets, shared tasks and evaluation methods may be found in BIBREF0.\nThe datasets for the DSL 2015 & DSL 2017 shared tasks BIBREF1 are often used in LID benchmarks and also available on Kaggle . The DSL datasets, like other LID datasets, consists of text sentences labelled by language. The 2017 dataset, for example, contains 14 languages over 6 language groups with 18000 training samples and 1000 testing samples per language.\nThe recently published JW300 parallel corpus BIBREF2 covers over 300 languages with around 100 thousand parallel sentences per language pair on average. In South Africa, a multilingual corpus of academic texts produced by university students with different mother tongues is being developed BIBREF3. The WiLI-2018 benchmark dataset BIBREF4 for monolingual written natural language identification includes around 1000 paragraphs of 235 languages. A possibly useful link can also be made BIBREF5 between Native Language Identification (NLI) (determining the native language of the author of a text) and Language Variety Identification (LVI) (classification of different varieties of a single language) which opens up more datasets. The Leipzig Corpora Collection BIBREF6, the Universal Declaration of Human Rights and Tatoeba are also often used sources of data.\nThe NCHLT text corpora BIBREF7 is likely a good starting point for a shared LID task dataset for the South African languages BIBREF8. The NCHLT text corpora contains enough data to have 3500 training samples and 600 testing samples of 300+ character sentences per language. Researchers have recently started applying existing algorithms for tasks like neural machine translation in earnest to such South African language datasets BIBREF9.\nExisting NLP datasets, models and services BIBREF10 are available for South African languages. These include an LID algorithm BIBREF11 that uses a character level n-gram language model. Multiple papers have shown that 'shallow' naive Bayes classifiers BIBREF12, BIBREF8, BIBREF13, BIBREF14, SVMs BIBREF15 and similar models work very well for doing LID. The DSL 2017 paper BIBREF1, for example, gives an overview of the solutions of all of the teams that competed on the shared task and the winning approach BIBREF16 used an SVM with character n-gram, parts of speech tag features and some other engineered features. The winning approach for DSL 2015 used an ensemble naive Bayes classifier. The fasttext classifier BIBREF17 is perhaps one of the best known efficient 'shallow' text classifiers that have been used for LID .\nMultiple papers have proposed hierarchical stacked classifiers (including lexicons) that would for example first classify a piece of text by language group and then by exact language BIBREF18, BIBREF19, BIBREF8, BIBREF0. Some work has also been done on classifying surnames between Tshivenda, Xitsonga and Sepedi BIBREF20. Additionally, data augmentation BIBREF21 and adversarial training BIBREF22 approaches are potentially very useful to reduce the requirement for data.\nResearchers have investigated deeper LID models like bidirectional recurrent neural networks BIBREF23 or ensembles of recurrent neural networks BIBREF24. The latter is reported to achieve 95.12% in the DSL 2015 shared task. In these models text features can include character and word n-grams as well as informative character and word-level features learnt BIBREF25 from the training data. The neural methods seem to work well in tasks where more training data is available.\nIn summary, LID of short texts, informal styles and similar languages remains a difficult problem which is actively being researched. Increased confusion can in general be expected between shorter pieces of text and languages that are more closely related. Shallow methods still seem to work well compared to deeper models for LID. Other remaining research opportunities seem to be data harvesting, building standardised datasets and creating shared tasks for South Africa and Africa. Support for language codes that include more languages seems to be growing and discoverability of research is improving with more survey papers coming out. Paywalls also seem to no longer be a problem; the references used in this paper was either openly published or available as preprint papers.\nIn summary, LID of short texts, informal styles and similar languages remains a difficult problem which is actively being researched.",

        "evidence": "In contrast to powder snow avalanches, wet snow avalanches are a low velocity suspension of snow and water, with the flow confined to the track surface (McClung, first edition 1999, page 108). The low speed of travel is due to the friction between the sliding surface of the track and the water saturated flow. Despite the low speed of travel (≈10–40 km/h), wet snow avalanches are capable of generating powerful destructive forces, due to the large mass and density. The body of the flow of a wet snow avalanche can plough through soft snow, and can scour boulders, earth, trees, and other vegetation; leaving exposed and often scored ground in the avalanche track. Wet snow avalanches can be initiated from either loose snow releases, or slab releases, and only occur in snowpacks that are water saturated and isothermally equilibrated to the melting point of water. The isothermal characteristic of wet snow avalanches has led to the secondary term of isothermal slides found in the literature (for example in Daffern, 1999, page 93). At temperate latitudes wet snow avalanches are frequently associated with climatic avalanche cycles at the end of the winter season, when there is significant daytime warming.",

We collect up to 3,200 tweets from each user and follow the standard tweet preprocessing procedures to remove the tweets without emojis and tweets containing less than ten words, and contents including the urls, mentions, and emails.\nFor acquiring the sentiment annotations, we first use Vader which is a rule-based sentiment analysis algorithm BIBREF17 for text tweets only to generate weak sentiment labels. The algorithm outputs sentiment scores ranging from -1 (negative) to 1 (positive) with neutral in the middle. We consider the sentiment analysis as a binary classification problem (positive sentiment and negative sentiment), we filter out samples with weak prediction scores within INLINEFORM0 and keep the tweets with strong sentiment signals. Emoji occurrences are calculated separately for positive tweets and negative tweets, and threshold is set to 2,000 to further filter out emojis which are less frequently used in at least one type of sentimental text. In the end, we have constructed a dataset with 1,492,065 tweets and 55 frequently used emojis in total. For the tweets with an absolute sentiment score over 0.70, we keep the auto-generated sentiment label as ground truth because the automatic annotation is reliable with high sentiment scores. On the other hand, we select a subset of the tweets with absolute sentiment scores between INLINEFORM1 for manual labeling by randomly sampling, following the distribution of emoji occurrences where each tweet is labeled by two graduate students. Tweets are discarded if the two annotations disagree with each other or they are labeled as neutral. In the end, we have obtained 4,183 manually labeled tweets among which 60% are used for fine-tuning and 40% are used for testing purposes. The remainder of the tweets with automatic annotations are divided into three sets: 60% are used for pre-training the bi-sense and conventional emoji embedding, 10% for validation and 30% are for testing. We do not include a “neutral” class because it is difficult to obtain valid neutral samples. For auto-generated labels, the neutrals are the samples with low absolute confidence scores and their sentiments are more likely to be model failures other than “true neutrals”. Moreover, based on the human annotations, most of the tweets with emojis convey non-neutral sentiment and only few neutral samples are observed during the manual labeling which are excluded from the manually labeled subset.\nFLOAT SELECTED: Table 1: Tweet examples with emojis.

        "evidence": "The Mughal Empire was an early-modern empire that controlled much of Indian subcontinent between the 16th and 19th centuries. For some two hundred years, the empire stretched from the outer fringes of the Indus river basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India.It included present day areas of India, Pakistan, Afghanistan and Bangladesh.\n\nThe Mughal empire is conventionally said to have been founded in 1526 by Babur, a warrior chieftain from what is today Uzbekistan, who employed aid from the neighboring Safavid and Ottoman empires, to defeat the Sultan of Delhi, Ibrahim Lodi, in the First Battle of Panipat, and to sweep down the plains of North India. The Mughal imperial structure, however, is sometimes dated to 1600, to the rule of Babur's grandson, Akbar. This imperial structure lasted until 1720, shortly after the death of the last major emperor, Aurangzeb, during whose reign the empire also achieved its maximum geographical extent. Reduced subsequently to the region in and around Old Delhi by 1760, the empire was formally dissolved by the British Raj after the Indian Rebellion of 1857.\n\nAlthough the Mughal empire was created and sustained by military warfare, it did not vigorously suppress the cultures and peoples it came to rule; rather it equalized and placated them through new administrative practices and diverse ruling elites, leading to more efficient, centralised, and standardized rule. The base of the empire's collective wealth was agricultural taxes, instituted by the third Mughal emperor, Akbar. These taxes, which amounted to well over half the output of a peasant cultivator, were paid in the well-regulated silver currency, and caused peasants and artisans to enter larger markets.\n\nThe relative peace maintained by the empire during much of the 17th century was a factor in India's economic expansion. The burgeoning European presence in the Indian Ocean, and its increasing demand for Indian raw and finished products, created still greater wealth in the Mughal courts. There was more conspicuous consumption among the Mughal elite, resulting in greater patronage of painting, literary forms, textiles, and architecture, especially during the reign of Shah Jahan. Among the Mughal UNESCO World Heritage Sites in South Asia are: Agra Fort, Fatehpur Sikri, Red Fort, Humayun's Tomb, Lahore Fort, Shalamar Gardens, and the Taj Mahal, which is described as \"the jewel of Muslim art in India, and one of the universally admired masterpieces of the world's heritage.\"",

        "answer": "The most common approach is to train models to imitate humans in large corpora of crowdsourced or scraped conversations.",
        "evidence": "Training a dialogue agent to converse like a human requires extensive supervision. The most common approach is to train models to imitate humans in large corpora of crowdsourced or scraped conversations BIBREF0 . These fully-supervised conversations tend to be expensive to collect in sufficient quantity and/or occur in settings with significant differences from the deployment environment BIBREF1 . Instead, dialogue agents would ideally learn directly from dialogue, the conversations they participate in after deployment, which are usually abundant, task-specific, dynamic, and cheap. This corresponds to the way humans learn to converse—not merely observing others engaging in “expert-level” conversations, but instead actively adjusting and correcting our speech based on feedback woven throughout our own conversations BIBREF2 , BIBREF3 . Giving a dialogue agent this ability would enable it to continuously improve and adapt over its lifetime, rather than requiring additional annotation costs for each and every improvement.\nHowever, naively training a dialogue agent on its own conversations yields poor results. For example, training a model on its own output can simply reinforce its existing failure modes, and mistakes by the agent can lead to absurd conversations that no longer resemble the target domain BIBREF4 . To combat this, one approach is to allow the agent to request feedback during conversations BIBREF5 , BIBREF6 , e.g., when it believes it is about to make a mistake. This approach, however, falls victim to the Dunning-Kruger effect BIBREF7 , which in this case suggests that a bad model will also be bad at knowing when it is doing a bad job. Regardless of when feedback is requested, existing methods typically require accompanying scalar rewards or adherence to particular templates or structure to ensure that the feedback is usable by the model BIBREF8 , BIBREF9 , BIBREF10 . These requirements may be acceptable for paid annotators, but they impose unnatural workflows on unpaid conversation partners in a standard dialogue environment. Humans are able to request and provide feedback using only natural language; ideally, dialogue agents would be able to do the same.\nIn this work we propose the self-feeding chatbot, a dialogue agent with the ability to extract new examples from the conversations it participates in after deployment (Figure FIGREF1 ). Concretely, in addition to being trained on the primary Dialogue task, the agent is trained to predict its speaking partner's satisfaction with its responses. When the conversation seems to be going well, the user's responses (but not the bot's own utterances) become the targets in new training examples for the Dialogue task. When the agent believes it has made a mistake, it instead requests feedback on what it could have said instead. Predicting the feedback that will be provided in a given context becomes an auxiliary task (Feedback) on which the model is also trained. Importantly, these new examples improve the agent's dialogue abilities while using only natural responses from the user that do not require special structure, accompanying numerical feedback, or additional human intervention in order to be used.\nWith this approach, the conversations the chatbot participates in are sliced into two complementary datasets—one largely protected from the chatbot's mistakes (Dialogue examples), and one which directly addresses them (Feedback examples). We validate our approach on the PersonaChat BIBREF11 dialogue dataset, finding empirically that regardless of the number of available supervised examples, the dialogue ability of the chatbot is always improved by adding the automatically extracted examples of either type, and improves the most by adding both.\nThe main contributions of this work thus include the following:\nThe datasets and models described in this paper are available via the ParlAI platform BIBREF12 , along with training code. Hyperparameter values are included in Appendix SECREF13 .\nThe most common approach is to train models to imitate humans in large corpora of crowdsourced or scraped conversations",

        "question": "How did early civilizations use dates and dried fruits?",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

Some network operators tried to throttle this traffic.\n\nIn May 2008, in an IETF Workshop on Peer-to-Peer Infrastructure, several areas of work were identified:\n\n1. A standardized interface for the exchange of information between the underlying IP network and an overlay network, such as a peer-to-peer network. The basic idea is, that if the overlay network was aware of the topology and the cost for sending traffic through the underlying IP network, it could optimize decisions with respect to the overlay network's topology (e.g., peer selection) and routing of traffic through the overlay network. The result would be better performance or Quality of Experience in the application while reducing the utilization of the underlying network infrastructure. This work item led to the establishment of the IETF ALTO working group.\n2. Content caches in the network. This has been studied in the IETF DECADE working group. However, no new protocol has been developed and standardized.\n3. A new congestion control mechanism in the transport layer for background traffic, which \"yields\" to standard TCP. This was worked on in the IETF LEDBAT working group and has been standardized in RFC 6817.\n4. A new DiffServ code point to mark IP packets to have a lower priority than the default \"best effort\" category has been standardized in RFC 8622.\n\nThe IETF ALTO working group was established in November 2008. The first deliverables were the problem statement, the requirements document, the specification of the core ALTO protocol and an ALTO server discovery mechanism. Since then, various extensions have been specified (see below) or are still work in progress (see IETF ALTO Datatracker).\n\nOriginally designed to support peer-to-peer file sharing, the concept is broadly applicable to many network problems. However, as of 2021 it has not achieved widespread deployment in the internet. Nevertheless, there have been experiments in Internet service provider (ISP) networks and a deployment to support large data transfers for the Large Hadron Collider at CERN.",

        "answer": "A bag representation in word level.",
        "evidence": "AliMe Bot is a kind of retrieval-based online service of E-commerce which collects a lot of predefined question-answering pairs. Through data analysis, we find that many variants of a question exist which means a sort of questions can correspond to a same answer. Based on the observation, naturally, we can view these questions with the same answer as a bag. Obviously, the bag contains diverse expressions of a question, which may provide more matching evidence than only one question due to the rich information contained in the bag. Motivated by the fact, different from existing query-question (Q-Q) matching method, we propose a new query-bag matching approach for retrieval-based chatbots. Concretely, when a user raises a query, the query-bag matching model provides the most suitable bag and returns the corresponding answer of the bag. To our knowledge, there is no query-bag matching study exists, and we focus on the new approach in this paper.\nRecalling the text matching task BIBREF0, recently, researchers have adopted the deep neural network to model the matching relationship. ESIM BIBREF1 judges the inference relationship between two sentences by enhanced LSTM and interaction space. SMN BIBREF2 performs the context-response matching for the open-domain dialog system. BIBREF3 BIBREF3 explores the usefulness of noisy pre-training in the paraphrase identification task. BIBREF4 BIBREF4 surveys the methods in query-document matching in web search which focuses on the topic model, the dependency model, etc. However, none of them pays attention to the query-bag matching which concentrates on the matching for a query and a bag containing multiple questions.\nWhen a user poses a query to the bot, the bot searches the most similar bag and uses the corresponding answer to reply to the user. The more information in the query covered by the bag, the more likely the bag's corresponding answer answers the query. What's more, the bag should not have too much information exceeding the query. Thus modelling the bag-to-query and query-to-bag coverage is essential in this task.\nIn this paper, we propose a simple but effective mutual coverage component to model the above-mentioned problem. The coverage is based on the cross-attention matrix of the query-bag pair which indicates the matching degree of elements between the query and bag. The mutual coverage is performed by stacking the cross-attention matrix along two directions, i.e., query and bag, in the word level respectively. In addition to the mutual coverage, a bag representation in word level is issued to help discover the main points of a bag. The bag representation then provides new matching evidence to the query-bag matching model.\nWe conduct experiments on the AliMe and Quora dataset for the query-bag matching based information-seeking conversation. Compared with baselines, we verify the effectiveness of our model. Our model obtains 0.05 and 0.03 $\\text{R}_{10}@1$ gains comparing to the strongest baseline in the two datasets. The ablation study shows the usefulness of the components. The contributions in this paper are summarized as follows: 1) To the best of our knowledge, we are the first to adopt query-bag matching in the information-seeking conversation. 2) We propose the mutual coverage model to measure the information coverage in the query-bag matching. 3) We release the composite Quora dataset to facilitate the research in this area.\ny. In addition to the mutual coverage, a bag representation in word level is issued to help discover the main points of a bag. The bag representation then provides new matching evidence to the query-bag matching model.",

In the second stage, article–section placement, we determine the best fitting section in an entity page. Here, we remedy the problem of incomplete entity section profiles by constructing section templates for specific entity classes. This allows us to add missing sections to entity pages. We carry out an extensive experimental evaluation on 351,983 news articles and 73,734 entities coming from 27 distinct entity classes. For the first stage, we achieve an overall performance with P=0.93, R=0.514 and F1=0.676, outperforming our baseline competitors significantly. For the second stage, we show that we can learn incrementally to determine the correct section for a news article based on section templates. The overall performance across different classes is P=0.844, R=0.885 and F1=0.860.\nIn the future, we will enhance our work by extracting facts from the suggested news articles.

        "evidence": "Words with multiple senses commonly exist in many languages. For example, the word bank can either mean a “financial establishment” or “the land alongside or sloping down to a river or lake”, based on different contexts. Such a word is called a “polyseme”. The task to identify the meaning of a polyseme in its surrounding context is called word sense disambiguation (WSD). Word sense disambiguation is a long-standing problem in natural language processing (NLP), and has broad applications in other NLP problems such as machine translation BIBREF0 . Lexical sample task and all-word task are the two main branches of WSD problem. The former focuses on only a pre-selected set of polysemes whereas the later intends to disambiguate every polyseme in the entire text. Numerous works have been devoted in WSD task, including supervised, unsupervised, semi-supervised and knowledge based learning BIBREF1 . Our work focuses on using supervised learning to solve all-word WSD problem.\nMost supervised approaches focus on extracting features from words in the context. Early approaches mostly depend on hand-crafted features. For example, IMS by BIBREF2 uses POS tags, surrounding words and collections of local words as features. These approaches are later improved by combining with word embedding features BIBREF0 , which better represents the words' semantic information in a real-value space. However, these methods neglect the valuable positional information between the words in the sequence BIBREF3 . The bi-directional Long-Short-Term-Memory (LSTM) approach by BIBREF3 provides one way to leverage the order of words. Recently, BIBREF4 improved the performance by pre-training a LSTM language model with a large unlabelled corpus, and using this model to generate sense vectors for further WSD predictions. However, LSTM significantly increases the computational complexity during the training process.\nThe development of the so called “fixed-size ordinally forgetting encoding” (FOFE) has enabled us to consider more efficient method. As firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence. FOFE has been applied to several NLP problems in the past, such as language model BIBREF5 , named entity recognition BIBREF6 , and word embedding BIBREF7 . The promising results demonstrated by the FOFE approach in these areas inspired us to apply FOFE in solving the WSD problem. In this paper, we will first describe how FOFE is used to encode sequence of any length into a fixed-size representation. Next, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data. Lastly, we provide the experiment results of our method on several WSD data sets to justify the equivalent performance as the state-of-the-art approach.\nTo demonstrate the applicability of our approach, we apply topic modelling to msmarco — a comprehension data set based on internet search queries — and collect examples that belong to a number of salient topics, producing 6 small to medium sized RC data sets for the following domains: biomedical, computing, film, finance, law and music.",

Although NMT can be significantly better than PBSMT in resource-rich scenarios, PBSMT performs better in low-resource scenarios BIBREF4 . Only by exploiting cross-lingual transfer learning techniques BIBREF5 , BIBREF6 , BIBREF7 , can the NMT performance approach PBSMT performance in low-resource scenarios.\nHowever, such methods usually require an NMT model trained on a resource-rich language pair like French INLINEFORM0 English (parent), which is to be fine-tuned for a low-resource language pair like Uzbek INLINEFORM1 English (child). On the other hand, multilingual approaches BIBREF8 propose to train a single model to translate multiple language pairs. However, these approaches are effective only when the parent target or source language is relatively resource-rich like English (En). Furthermore, the parents and children models should be trained on similar domains; otherwise, one has to take into account an additional problem of domain adaptation BIBREF9 .\nIn this paper, we work on a linguistically distant and thus challenging language pair Japanese INLINEFORM0 Russian (Ja INLINEFORM1 Ru) which has only 12k lines of news domain parallel corpus and hence is extremely resource-poor. Furthermore, the amount of indirect in-domain parallel corpora, i.e., Ja INLINEFORM2 En and Ru INLINEFORM3 En, are also small. As we demonstrate in Section SECREF4 , this severely limits the performance of prominent low-resource techniques, such as multilingual modeling, back-translation, and pivot-based PBSMT.

        "evidence": "While specific rules for triathlon can vary depending on the governing body (e.g. World Triathlon, USA Triathlon), as well as for an individual race venue, there are some basic universal rules. Traditionally, triathlon is an individual sport and each athlete is competing against the course and the clock for the best time. As such, athletes are not allowed to receive assistance from anyone else outside the race, with the exception of race-sanctioned aid volunteers who distribute food and water on the course.\n\n\nTransition area (bicycles) of Hamburg Triathlon, 2002\nTriathlons are timed in five sequential sections:\n\nfrom the start of the swim to the beginning of the first transition (swim time);\nfrom the beginning of the first transition to the end of the first transition (T1 time);\nfrom the start of the cycling to the end of the cycling leg (cycling time);\nfrom the beginning of the second transition to the end of the second transition (T2 time);\nfinally from the start of the run to the end of the run, at which time the triathlon is completed.\nResults are usually posted on official websites and will show for each triathlete his/her swim time; cycle time (with transitions included); run time; and total time. Some races also post transition times separately.\n\nOther rules of triathlon vary from race to race and generally involve descriptions of allowable equipment (for example, wetsuits are allowed in USAT events in the swimming stage of some races when the water temperature is below 25.6 °C (78.1 °F)), and prohibitions against interference between athletes. Additionally, the use of flippers or other swim propulsion and flotation aids are illegal in triathlon and can result in disqualification.\n\nOne rule involving the cycle leg is that the competitor's helmet must be donned before the competitor mounts (or even takes possession of, in certain jurisdictions) the bike, and it must remain on until the competitor has dismounted; the competitor may not be required to wear the helmet when not on the bicycle (e.g. while repairing a mechanical problem). Failure to comply with this rule will result in disqualification. Additionally, while on the bike course, all bicycles shall be propelled only by human force and human power. Other than pushing a bicycle, any propulsive action brought on by use of the hands is prohibited. Should a competitor's bike malfunction they can proceed with the race as long as they are doing so with their bicycle in tow. There are also strict rules regarding the 'bike mount' line. Competitors may not begin riding their bicycle out of transition until they are over a clearly marked line. Mounting the bike prior to this may incur a penalty (example: a 15-second time penalty at the London 2012 Olympics was imposed on Jonathan Brownlee, a competitor from Great Britain, for mounting his bike too early.)\n\nOther time penalties can be incurred during the race for, among other things, drafting on the bike in a non-drafting race, improper passing, littering on course, and unsportsmanlike conduct.",

His films are characterized by stylized violence, extended dialogue including the pervasive use of profanity and references to popular culture.\n\nTarantino began his career as an independent filmmaker with the release of the crime film Reservoir Dogs in 1992. His second film, Pulp Fiction (1994), a dark comedy crime thriller, was a major success with critics and audiences winning numerous awards, including the Palme d'Or and the Academy Award for Best Original Screenplay. In 1996, he appeared in From Dusk till Dawn, also writing the screenplay. Tarantino's third film, Jackie Brown (1997), paid homage to blaxploitation films.\n\nIn 2003, Tarantino directed Kill Bill: Volume 1, inspired by the traditions of martial arts films; it was followed by Volume 2 in 2004. He then made the exploitation-slasher Death Proof (2007), part of a double feature with Robert Rodriguez released under the collective title Grindhouse. His next film, Inglourious Basterds (2009), follows an alternate account of World War II. He followed this with Django Unchained (2012), a slave revenge Spaghetti Western, which won him his second Academy Award for Best Original Screenplay. His eighth film The Hateful Eight (2015) is a revisionist Western thriller and opened to audiences with a roadshow release. His most recent film, Once Upon a Time in Hollywood (2019), is a comedy drama set in the late 1960s about the transition of Old Hollywood to New Hollywood. A novelization of the film was also published in 2021, becoming his debut novel.\n\nTarantino's work has been subject to controversy, such as the depictions of violence, frequent inclusion of racial slurs and the alleged negligence of safety in his handling of stunt scenes on Kill Bill: Volume 2. During Tarantino's career, his films have garnered a cult following, as well as critical and commercial success, he has been considered \"the single most influential director of his generation\".

        "evidence": "The Unix operating system was conceived and implemented in 1969, at AT&T's Bell Labs, in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. First released in 1971, Unix was written entirely in assembly language, as was common practice at the time. In 1973, in a key pioneering approach, it was rewritten in the C programming language by Dennis Ritchie (with the exception of some hardware and I/O routines). The availability of a high-level language implementation of Unix made its porting to different computer platforms easier.\n\nDue to an earlier antitrust case forbidding it from entering the computer business, AT&T licensed the operating system's source code as a trade secret to anyone who asked. As a result, Unix grew quickly and became widely adopted by academic institutions and businesses. In 1984, AT&T divested itself of its regional operating companies, and was released from its obligation not to enter the computer business; freed of that obligation, Bell Labs began selling Unix as a proprietary product, where users were not legally allowed to modify it.\n\nOnyx Systems began selling early microcomputer-based Unix workstations in 1980. Later, Sun Microsystems, founded as a spin-off of a student project at Stanford University, also began selling Unix-based desktop workstations in 1982. While Sun workstations didn't utilize commodity PC hardware like Linux was later developed for, it represented the first successful commercial attempt at distributing a primarily single-user microcomputer that ran a Unix operating system.\n\nWith Unix increasingly \"locked in\" as a proprietary product, the GNU Project, started in 1983 by Richard Stallman, had the goal of creating a \"complete Unix-compatible software system\" composed entirely of free software. Work began in 1984. Later, in 1985, Stallman started the Free Software Foundation and wrote the GNU General Public License (GNU GPL) in 1989. By the early 1990s, many of the programs required in an operating system (such as libraries, compilers, text editors, a command-line shell, and a windowing system) were completed, although low-level elements such as device drivers, daemons, and the kernel, called GNU Hurd, were stalled and incomplete.\n\nMINIX was created by Andrew S. Tanenbaum, a computer science professor, and released in 1987 as a minimal Unix-like operating system targeted at students and others who wanted to learn operating system principles. Although the complete source code of MINIX was freely available, the licensing terms prevented it from being free software until the licensing changed in April 2000.\n\nAlthough not released until 1992, due to legal complications, development of 386BSD, from which NetBSD, OpenBSD and FreeBSD descended, predated that of Linux.\n\nLinus Torvalds has stated on separate occasions that if the GNU kernel or 386BSD had been available at the time (1991), he probably would not have created Linux.",

In 1991 he released version 0.02; Version 1.0 of the Linux kernel, the core of the operating system, was released in 1994. About the same time, American software developer Richard Stallman and the FSF made efforts to create an open-source UNIX-like operating system called GNU. In contrast to Torvalds, Stallman and the FSF started by creating utilities for the operating system first. These utilities were then added to the Linux kernel to create a complete system called GNU/Linux, or, less precisely, just Linux.",

        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nIn this thesis proposal, I will present KALM, a system for knowledge authoring and question answering.",

        "evidence": "CLIR systems retrieve documents written in a language that is different from search query language BIBREF0 . The primary objective of CLIR is to translate or project a query into the language of the document repository BIBREF1 , which we refer to as Retrieval Corpus (RC). To this end, common CLIR approaches translate search queries using a Machine Translation (MT) model and then use a monolingual IR system to retrieve from RC. In this process, a translation model is treated as a black box BIBREF2 , and it is usually trained on a sentence level parallel corpus, which we refer to as Translation Corpus (TC).\nWe address a pitfall of using existing MT models for query translation BIBREF1 . An MT model trained on TC does not have any knowledge of RC. In an extreme setting, where there are no common terms between the target side of TC and RC, a well trained and tested translation model would fail because of vocabulary mismatch between the translated query and documents of RC. Assuming a relaxed scenario where some commonality exists between two corpora, a translation model might still perform poorly, favoring terms that are more likely in TC but rare in RC. Our hypothesis is that a search query translation model would perform better if a translated query term is likely to appear in the both retrieval and translation corpora, a property we call balanced translation.\nTo achieve balanced translations, it is desired to construct an MT model that is aware of RC vocabulary. Different types of MT approaches have been adopted for CLIR task, such as dictionary-based MT, rule-based MT, statistical MT etc. BIBREF3 . However, to the best of our knowledge, a neural search query translation approach has yet to be taken by the community. NMT models with attention based encoder-decoder techniques have achieved state-of-the-art performance for several language pairs BIBREF4 . We propose a multi-task learning NMT architecture that takes RC vocabulary into account by learning Relevance-based Auxiliary Task (RAT). RAT is inspired from two word embedding learning approaches: Relevance-based Word Embedding (RWE) BIBREF5 and Continuous Bag of Words (CBOW) embedding BIBREF6 . We show that learning NMT with RAT enables it to generate balanced translation.\nNMT models learn to encode the meaning of a source sentence and decode the meaning to generate words in a target language BIBREF7 . In the proposed multi-task learning model, RAT shares the decoder embedding and final representation layer with NMT. Our architecture answers the following question: In the decoding stage, can we restrict an NMT model so that it does not only generate terms that are highly likely in TC?. We show that training a strong baseline NMT with RAT roughly achieves 16% improvement over the baseline. Using a qualitative analysis, we further show that RAT works as a regularizer and prohibits NMT to overfit to TC vocabulary.\nWe address a pitfall of using existing MT models for query translation (Sokokov et al., 2013). An MT model trained on TC does not have any knowledge of RC. In an extreme setting, where there are no common terms between the target side of TC and RC, a well trained and tested translation model would fail because of vocabulary mismatch between the translated query and documents of RC.

        "question": "Is fine-tuning required by the pre-trained model?",
        "answer": "Yes.",
        "evidence": "Our system comprises of following three steps:\nCloze generation: Most of the documents typically follow a template, they begin with an introduction that provides an overview and a brief summary for what is to follow. We assume such a structure while constructing our cloze style questions. When there is no clear demarcation, we treat the first $K\\%$ (hyperparameter, in our case 20%) of the document as the introduction. While noisy, this heuristic generates a large number of clozes given any corpus, which we found to be beneficial for semi-supervised learning despite the noise.\nWe use a standard NLP pipeline based on Stanford CoreNLP (for SQuAD, TrivaQA and PubMed) and the BANNER Named Entity Recognizer (only for PubMed articles) to identify entities and phrases. Assume that a document comprises of introduction sentences $\\lbrace q_1, q_2, ... q_n\\rbrace $ , and the remaining passages $\\lbrace p_1, p_2, .. p_m\\rbrace $ . Additionally, let's say that each sentence $q_i$ in introduction is composed of words $\\lbrace w_1, w_2, ... w_{l_{q_i}}\\rbrace $ , where $l_{q_i}$ is the length of $q_i$ . We consider a $\\text{match} (q_i, p_j)$ , if there is an exact string match of a sequence of words $\\lbrace w_k, w_{k+1}, .. w_{l_{q_i}}\\rbrace $ between the sentence $q_i$ and passage $p_j$ . If this sequence is either a noun phrase, verb phrase, adjective phrase or a named entity in $\\lbrace p_1, p_2, .. p_m\\rbrace $0 , as recognized by CoreNLP or BANNER, we select it as an answer span $\\lbrace p_1, p_2, .. p_m\\rbrace $1 . Additionally, we use $\\lbrace p_1, p_2, .. p_m\\rbrace $2 as the passage $\\lbrace p_1, p_2, .. p_m\\rbrace $3 and form a cloze question $\\lbrace p_1, p_2, .. p_m\\rbrace $4 from the answer bearing sentence $\\lbrace p_1, p_2, .. p_m\\rbrace $5 by replacing $\\lbrace p_1, p_2, .. p_m\\rbrace $6 with a placeholder. As a result, we obtain passage-question-answer ( $\\lbrace p_1, p_2, .. p_m\\rbrace $7 ) triples (Table 1 shows an example). As a post-processing step, we prune out $\\lbrace p_1, p_2, .. p_m\\rbrace $8 triples where the word overlap between the question (Q) and passage (P) is less than 2 words (after excluding the stop words).\nThe process relies on the fact that answer candidates from the introduction are likely to be discussed in detail in the remainder of the article. In effect, the cloze question from the introduction and the matching paragraph in the body forms a question and context passage pair. We create two cloze datasets, one each from Wikipedia corpus (for SQuAD and TriviaQA) and PUBMed academic papers (for the BioASQ challenge), consisting of 2.2M and 1M clozes respectively. From analyzing the cloze data manually, we were able to answer 76% times for the Wikipedia set and 80% times for the PUBMed set using the information in the passage. In most cases the cloze paraphrased the information in the passage, which we hypothesized to be a useful signal for the downstream QA task.\nWe also investigate the utility of forming subsets of the large cloze corpus, where we select the top passage-question-answer triples, based on the different criteria, like i) jaccard similarity of answer bearing sentence in introduction and the passage ii) the tf-idf scores of answer candidates and iii) the length of answer candidates. However, we empirically find that we were better off using the entire set rather than these subsets.\nPre-training: We make use of the generated cloze dataset to pre-train an expressive neural network designed for the task of reading comprehension. We work with two publicly available neural network models – the GA Reader BIBREF2 (to enable comparison with prior work) and BiDAF + Self-Attention (SA) model from BIBREF1 (which is among the best performing models on SQuAD and TriviaQA). After pretraining, the performance of BiDAF+SA on a dev set of the (Wikipedia) cloze questions is 0.58 F1 score and 0.55 Exact Match (EM) score. This implies that the cloze corpus is neither too easy, nor too difficult to answer.\nFine Tuning: We fine tune the pre-trained model, from the previous step, over a small set of labelled question-answer pairs. As we shall later see, this step is crucial, and it only requires a handful of labelled questions to achieve a significant proportion of the performance typically attained by training on tens of thousands of questions.\nFine Tuning: We fine tune the pre-trained model, from the previous step, over a small set of labelled question-answer pairs.

A descendant of the Puritans, he was the son of Soviah (née Wilson) Edson and Opher Edson.\n\nHe was educated at the local schools and at the Chester Academy in Vermont.\n\nCareer\nBusiness\nAt age twenty, Edson moved to Albany to work in his brother Cyrus' distillery, becoming a partner three years later.\n\nHe left the distillery after his brother's death and started a produce business, which he relocated to New York City in 1866. His venture proved successful during the American Civil War, making Edson wealthy and enabling him to engage in civic, religious and charitable causes. He was an active Episcopalian and a member of Saint James Church, Fordham, in the Bronx.\n\nIn 1873, he became one of the city's most important business leaders when he was appointed President of the New York Produce Exchange.\n\nPolitics\nAn anti-Tammany Democrat, in 1882 he was nominated for Mayor through the efforts of Tammany Hall boss John Murphy to avoid a Democratic Party split between organization loyalists and reformers. Upon taking office in 1883, he angered reformers by appointing Tammany men to key jobs, but he soon embraced civil service reform and other honest government measures.\n\nDuring his term the Brooklyn Bridge was dedicated, the Manhattan Municipal Building was constructed, and work was completed on the city's new water supply, the Croton Aqueduct. He appointed the commission responsible for the selection and location of public lands for parks in the Bronx, which came to include Van Cortlandt, Bronx, Pelham Bay, Crotona, Claremont and St. Mary's Parks, and the Mosholu, Bronx River, Pelham, and Crotona Parkways.\n\nAfter Edson split with Tammany the 1884 Democratic nomination for Mayor went to William Russell Grace, who had also preceded Edson as Mayor, and Edson retired from politics at the completion of his term in 1885.\n\nAfter leaving the mayor's office, Edson returned to his business interests and continued his philanthropic activities.\n\nPersonal life\nIn 1856, Edson was married to Frances Cameron \"Fannie\" Wood (1835–1893), the daughter of Benjamin Howland Wood. Fannie was the granddaughter of Jethro Wood, inventor of the cast-iron moldboard plow. They owned a homestead in Morris Heights, Bronx that consisted of three acres, a stately residence, stable and barn, which he exchanged for 247 Central Park West, two doors south of the corner of 85th Street, in 1893. Together, Fannie and Franklin were the parents of:\n\nCyrus Edson (1857–1903), a doctor who married Virginia Churchill Paige (1853–1891). He served as the President of the Board of Health.\nFranklin (1859-1926), who married Elsie Squier.\nDavid Orr Edson (1862–1923), a doctor.\nHenry Townsend Edson (1864–1903), who married Margarita Diehl. In 1903, Henry Edson murdered his friend's wife and then committed suicide.\nEdith Edson (b. 1870), who married Willis Benner.\nRobert S. (1873-1941), who married Fanny Ropes.\nEthel Townsend Edson (b. 1877), who married Arthur Hoffman Van Brunt (b. 1865).\nHe died at his home in Manhattan on September 24, 1904.

        "evidence": "In the era of social media and networking platforms, Twitter has been doomed for abuse and harassment toward users specifically women. In fact, online harassment becomes very common in Twitter and there have been a lot of critics that Twitter has become the platform for many racists, misogynists and hate groups which can express themselves openly. Online harassment is usually in the form of verbal or graphical formats and is considered harassment, because it is neither invited nor has the consent of the receipt. Monitoring the contents including sexism and sexual harassment in traditional media is easier than monitoring on the online social media platforms like Twitter. The main reason is because of the large amount of user generated content in these media. So, the research about the automated detection of content containing sexual harassment is an important issue and could be the basis for removing that content or flagging it for human evaluation. The basic goal of this automatic classification is that it will significantly improve the process of detecting these types of hate speech on social media by reducing the time and effort required by human beings.\nPrevious studies have been focused on collecting data about sexism and racism in very broad terms or have proposed two categories of sexism as benevolent or hostile sexism BIBREF0, which undermines other types of online harassment. However, there is no much study focusing on different types online harassment alone attracting natural language processing techniques.\nIn this paper we present our work, which is a part of the SociaL Media And Harassment Competition of the ECML PKDD 2019 Conference. The topic of the competition is the classification of different types of harassment and it is divided in two tasks. The first one is the classification of the tweets in harassment and non-harassment categories, while the second one is the classification in specific harassment categories like indirect harassment, physical and sexual harassment as well. We are using the dataset of the competition, which includes text from tweets having the aforementioned categories. Our approach is based on the Recurrent Neural Networks and particularly we are using a deep, classification specific attention mechanism. Moreover, we present a comparison between different variations of this attention-based approach like multi-attention and single attention models. The next Section includes a short description of the related work, while the third Section includes a description of the dataset. After that, we describe our methodology. Finally, we describe the experiments and we present the results and our conclusion.\nPrevious studies have been focused on collecting data about sexism and racism in very broad terms or have proposed two categories of sexism as benevolent or hostile sexism [1], which undermines other types of online harassment.

        "evidence": "Table TABREF26 reports the evaluation of our approach on both the CyberAttack and PoliticianDeath event categories. Our approach is configured such that each iteration starts with 1 new keyword discovered in the previous iteration.\nOur approach improves LR by 5.17% (Accuracy) and 18.38% (AUC), and MLP by 10.71% (Accuracy) and 30.27% (AUC) on average. Such significant improvements clearly demonstrate that our approach is effective at improving model performance. We observe that the target models generally converge between the 7th and 9th iteration on both datasets when performance is measured by AUC. The performance can slightly degrade when the models are further trained for more iterations on both datasets. This is likely due to the fact that over time, the newly discovered keywords entail lower novel information for model training. For instance, for the CyberAttack dataset the new keyword in the 9th iteration `election' frequently co-occurs with the keyword `russia' in the 5th iteration (in microposts that connect Russian hackers with US elections), thus bringing limited new information for improving the model performance. As a side remark, we note that the models converge faster when performance is measured by accuracy. Such a comparison result confirms the difference between the metrics and shows the necessity for more keywords to discriminate event-related microposts from non event-related ones.\nOur approach improves LR by 5.17% (Accuracy) and 18.38% (AUC), and MLP by 10.71% (Accuracy) and 30.27% (AUC) on average.",

        "evidence": "“Laughter is the best Medicine” is a saying which is popular with most of the people. Humor is a form of communication that bridges the gap between various languages, cultures, ages and demographics. That's why humorous content with funny and witty hashtags are so much popular on social media. It is a very powerful tool to connect with the audience. Automatic Humor Recognition is the task of determining whether a text contains some level of humorous content or not. First conference on Computational humor was organized in 1996, since then many research have been done in this field. kao2016computational does pun detection in one-liners and dehumor detects humor in Yelp reviews. Because of the complex and interesting aspects involved in detecting humor in texts, it is one of the challenging research field in Natural Language Processing BIBREF3 . Identifying humor in a sentence sometimes require a great amount of external knowledge to completely understand it. There are many types of humor, namely anecdotes, fantasy, insult, irony, jokes, quote, self deprecation etc BIBREF4 , BIBREF5 . Most of the times there are different meanings hidden inside a sentence which is grasped differently by individuals, making the task of humor identification difficult, which is why the development of a generalized algorithm to classify different type of humor is a challenging task.\nMajority of the researches on social media texts is focused on English. A study by schroeder2010half shows that, a high percentage of these texts are in non-English languages. fischer2011language gives some interesting information about the languages used on Twitter based on the geographical locations. With a huge amount of such user generated data available on social media, there is a need to develop technologies for non-English languages. In multilingual regions like South Asia, majority of the social media users speak more than two languages. In India, Hindi is the most spoken language (spoken by 41% of the population) and English is the official language of the country. Twitter has around 23.2 million monthly active users in India. Native speakers of Hindi often put English words in the sentences and transliterate the whole sentence to Latin script while posting on social media, thereby making the task of automatic text classification a very challenging problem. Linguists came up with a term for any type of language mixing, known as `code-mixing' or `code-switching' BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . Both the terms are used interchangeably, but there is a slight difference between the two terms. Code-mixing refers to the insertion of words, phrases, and morphemes of one language into a statement or an expression of another language, whereas transliteration of every word in a sentence to another script ( here Devanagari to Latin) is coined code-switching BIBREF10 . The first tweet in Figure 1 is an example of code-mixing and second is an example of code-switching. In this paper, we use code-mixing to denote both cases.\nIn this paper, we present a freely available corpus containing code-mixed tweets in Hindi and English language with tweets written in Latin script. Tweets are manually classified into humorous and non-humorous classes. Moreover, each token in the tweets is also given a language tag which determines the source or origin language of the token (English or Hindi). The paper is divided in sections as follows, we start by describing the corpus and the annotation scheme in Section 2. Section 3 summarizes our supervised classification system which includes pre-processing of the tweets in the dataset and the feature extraction followed by the method used to identify humor in tweets. In the next subsection, we describe the classification model and the results of the experiments conducted using character and word level features. In the last section, we conclude the paper followed by future work and references.\nIn this paper, we present a freely available corpus containing code-mixed tweets in Hindi and English language with tweets written in Latin script.",

During grand slam matches, players can run anywhere from 3 to 4 miles with most of the movement being lateral. The top players have the distinct advantage that they have large support staff including dedicated physios and massage therapists who can get the player ready for subsequent matches. Besides, the top players have coaches who may have themselves won slams, and thus carry a wealth of experience. Sometimes players also enlist the services of data analysts who can do opponent video/data analysis to determine patterns/preferences of opponents. Such massive support staff carry a lot of payroll that most unseeded players cannot afford.

        "question": "What are the four attributes the authors identified as recommended for good news?",
        "answer": "Salience, relative authority, novelty and placement.",
        "evidence": "Wikipedia is the largest source of open and collaboratively curated knowledge in the world. Introduced in 2001, it has evolved into a reference work with around 5m pages for the English Wikipedia alone. In addition, entities and event pages are updated quickly via collaborative editing and all edits are encouraged to include source citations, creating a knowledge base which aims at being both timely as well as authoritative. As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page. However, not all information sources are equal. The online presence of major news outlets is an authoritative source due to active editorial control and their articles are also a timely container of facts. In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them). However, such an approach lacks in (a) reproducibility since rankings vary with time with obvious bias to recent news (b) maintainability since document acquisition for each entity has to be periodically performed. To this effect, our news suggestion considers a news article as input, and determines if it is valuable for Wikipedia. Specifically, given an input news article INLINEFORM0 and a state of Wikipedia, the news suggestion problem identifies the entities mentioned in INLINEFORM1 whose entity pages can improve upon suggesting INLINEFORM2 . Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower. Third, a good recommendation should be able to identify novel news by minimizing redundancy coming from multiple news articles. Finally, addition of facts is facilitated if the recommendations are fine-grained, i.e., recommendations are made on the section level rather than the page level (placement).\nApproach and Contributions. We propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity's salience in the news article, its relative authority and the novelty of the article to the entity page. The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years. The existing news references in the entity pages along with their reference date act as our ground-truth to evaluate our approach. In summary, we make the following contributions.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement.",

For example, statistics have shown that over 74% of US pet owners have a dog, in comparison with 47% owning a cat. \nThe reason for their popularity has to come down to their personality. Commonly, dogs are very social and affectionate creatures who enjoy spending time with their owners.

For example. you should be looking at the exit of a turn as you enter the turn (or the apex if it's a wide turn)\n3. Slow in, fast out - Cornering can be particularly tricky, because we tend to turn in too fast and too early, which can set up for a slow exit.

In the following, we briefly describe the different variants of Rouge:\nRouge-L, Rouge-W, Rouge-S and Rouge-SU were later extended to consider both the recall and precision. In calculating Rouge, stopword removal or stemming can also be considered, resulting in more variants.\nIn the summarization literature, despite the large number of variants of Rouge, only one or very few of these variants are often chosen (arbitrarily) for evaluation of the quality of the summarization approaches. When Rouge was proposed, the original variants were only recall-oriented and hence the reported correlation results BIBREF1 . The later extension of Rouge family by precision were only reflected in the later versions of the Rouge toolkit and additional evaluation of its effectiveness was not reported. Nevertheless, later published work in summarization adopted this toolkit for its ready implementation and relatively efficient performance.\nThe original Rouge metrics show high correlations with human judgments of the quality of summaries on the DUC 2001-2003 benchmarks. However, these benchmarks consist of newswire data and are intrinsically very different than other summarization tasks such as summarization of scientific papers. We argue that Rouge is not the best metric for all summarization tasks and we propose an alternative metric for evaluation of scientific summarization. The proposed alternative metric shows much higher and more consistent correlations with manual judgments in comparison with the well-established Rouge.\nROUGE has been the most widely used family of metrics in summarization evaluation. In the following, we briefly describe the different variants of ROUGE: – ROUGE-N: ROUGE-N was originally a recall oriented metric that considered N-gram recall between a system generated summary and the corresponding gold human summaries. In later versions, in addition to the recall, precision was also considered in ROUGE-N, which is the precision of N-grams in the system generated summary with respect to the gold human summary. To combine both precision and recall, F1 scores are often reported. Common values of N range from 1 to 4. – ROUGE-L: This variant of ROUGE compares the system generated summary and the human generated summary based on the Longest Common Subsequences (LCS) between them. The premise is that, longer LCS between the system and human summaries shows more similarity and therefore higher quality of the system summary – ROUGE-W: One problem with ROUGE-L is that all LCS with same lengths are rewarded equally. The LCS can be either related to a consecutive set of words or a long sequence with many gaps. While ROUGE-L treats all sequence matches equally, it makes sense that sequences with many gaps receive lower scores in comparison with consecutive matches. ROUGE-W considers an additional weighting function that awards consecutive matches more than non-consecutive ones. – ROUGE-S: ROUGE-S computes the skip-bigram co-occurrence statistics between the two summaries. It is similar to ROUGE-2 except that it allows gaps between the bigrams by skipping middle tokens. – ROUGE-SU: ROUGE-S does not give any credit to a system generated sentence if the sentence does not have any word pair co-occurring in the reference sentence. To solve this potential problem, ROUGE-SU was proposed which is an extension of ROUGE-S that also considers unigram matches between the two summaries. ROUGE-L, ROUGE-W, ROUGE-S and ROUGE-SU were later extended to consider both the recall and precision. In calculating ROUGE, stopword removal or stemming can also be considered, resulting in more variants. In the summarization literature, despite the large number of variants of ROUGE, only one or very few of these variants are often chosen (arbitrarily) for evaluation of the quality of the summarization approaches. When ROUGE was proposed, the original variants were only recall-oriented and hence the reported correlation results (Lin, 2004).",

Gaining an early following as one of the first British psychedelic groups, they were distinguished by their extended compositions, sonic experimentation, philosophical lyrics and elaborate live shows. They became a leading band of the progressive rock genre, cited by some as the greatest progressive rock band of all time.\n\nPink Floyd were founded in 1965 by Syd Barrett (guitar, lead vocals), Nick Mason (drums), Roger Waters (bass guitar, vocals), and Richard Wright (keyboards, vocals). Under Barrett's leadership, they released two charting singles and the successful debut album The Piper at the Gates of Dawn (1967). The guitarist and vocalist David Gilmour joined in January 1968; Barrett left in April 1968 due to deteriorating mental health. Waters became the primary lyricist and thematic leader, devising the concepts behind Pink Floyd's most successful albums, The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977) and The Wall (1979). The musical film based on The Wall, Pink Floyd – The Wall (1982), won two BAFTA Awards. Pink Floyd also composed several film scores.\n\nFollowing personal tensions, Wright left Pink Floyd in 1981, followed by Waters in 1985. Gilmour and Mason continued as Pink Floyd, rejoined later by Wright. They produced the albums A Momentary Lapse of Reason (1987) and The Division Bell (1994), backed by major tours, before entering a long hiatus. In 2005, all but Barrett reunited for a performance at the global awareness event Live 8. Barrett died in 2006, and Wright in 2008. The last Pink Floyd studio album, The Endless River (2014), was based on unreleased material from the Division Bell recording sessions. In 2022, Gilmour and Mason reformed Pink Floyd to release the song \"Hey, Hey, Rise Up!\" in protest of the Russo-Ukrainian War.\n\nBy 2013, Pink Floyd had sold more than 250 million records worldwide, making them one of the best-selling music artists of all time. The Dark Side of the Moon and The Wall were inducted into the Grammy Hall of Fame, and these albums and Wish You Were Here are among the best-selling albums of all time. Four Pink Floyd albums topped the US Billboard 200, and five topped the UK Albums Chart. Pink Floyd's hit singles include \"See Emily Play\" (1967), \"Money\" (1973), \"Another Brick in the Wall, Part 2\" (1979), \"Not Now John\" (1983), \"On the Turning Away\" (1987) and \"High Hopes\" (1994).

        "answer": "If phrases are added without accounting component similarity (Runs 2, 3), the quality of topics decreases: the more phrases are added, the more the quality degrades.",
        "evidence": "To estimate the quality of topic models in a real task, we chose Islam informational portal \"Golos Islama\" (Islam Voice) (in Russian). This portal contains both news articles related to Islam and articles discussing Islam basics. We supposed that the thematic analysis of this specialized site can be significantly improved with domain-specific knowledge described in the thesaurus form. We extracted the site contents using Open Web Spider and obtained 26,839 pages.\nTo combine knowledge with a topic model, we used RuThes thesaurus together with the additional block of the Islam thesaurus. The Islam thesaurus contains more than 5 thousand Islam-related terms including single words and expressions.\nFor each combined model, we ran two experiments with 100 topics and with 200 topics. The generated topics were evaluated by two linguists, who had previously worked on the Islam thesaurus. The evaluation task was formulated as follows: the experts should read the top elements of the generated topics and try to formulate labels of these topics. The labels should be different for each topic in the set generated with a specific model. The experts should also assign scores to the topics' labels:\nThen we can sum up all the scores for each model under consideration and compare the total scores in value. Thus, maximum values of the topic score are 200 for a 100-topic model and 400 for a 200-topic model. In this experiment we do not measure inter-annotator agreement for each topic, but try to get expert's general impression.\nDue to the complicated character of the Islam portal contents for automatic extraction (numerous words and names difficult for Russian morphological analyzers), we did not use automatic extraction of multiword expressions and exploited only phrases described in RuThes or in the Islam Thesaurus. We added thesaurus phrases in two ways: most frequent 1000 phrases (as in BIBREF14 , BIBREF16 ) and phrases with frequency more than 10 (More10phrases): the number of such phrases is 9351.\nThe results of the evaluation are shown in Table 5. The table contains the overall expert scores for a topic model (Score), kernel uniqueness as in the previous section (KernU), perplexity (Prpl). Also for each model kernels, we calculated the average number of known relations between topics’s elements: thesaurus relations (synonyms and direct relations between concepts) and component-based relations between phrases (Relc).\nIt can be seen that if we add phrases without accounting component similarity (Runs 2, 3), the quality of topics decreases: the more phrases are added, the more the quality degrades. The human scores also confirm this fact. But if the similarity between phrase components is considered then the quality of topics significantly improves and becomes better than for unigram models (Runs 4, 5). All measures are better. Relational coherence between kernel elements also grows. The number of added phrases is not very essential.\nAdding unary synonyms decreases the quality of the models (Run 6) according to human scores. But all other measures behave differently: kernel uniqueness is high, perplexity decreases, relational coherence grows. The problem of this model is in that non-topical, general words are grouped together, reinforce one another but do not look as related to any topic. Adding all thesaurus relations is not very beneficial (Runs 7, 8). If we consider all relations except hyponyms, the human scores are better for corresponding runs (Runs 9, 10). Relational coherence in topics’ kernels achieves very high values: the quarter of all elements have some relations between each other, but it does not help to improve topics. The explanation is the same: general words can be grouped together.\nAt last, we removed General Lexicon concepts from the RuThes data, which are top-level, non-thematic concepts that can be met in arbitrary domains BIBREF19 and considered all-relations and without-hyponyms variants (Runs 11, 12). These last variants achieved maximal human scores because they add thematic knowledge and avoid general knowledge, which can distort topics. Kernel uniqueness is also maximal.\nTable 6 shows similar topics obtained with the unigram, phrase-enriched (Run 5) and the thesaurus-enriched topic model (Run 12). The Run-5 model adds thesaurus phrases with frequency more than 10 and accounts for the component similarity between phrases. The Run-12 model accounts both component relations and hypernym thesaurus relations. All topics are of high quality, quite understandable. The experts evaluated them with the same high scores.\nPhrase-enriched and thesaurus-enriched topics convey the content using both single words and phrases. It can be seen that phrase-enriched topics contain more phrases. Sometimes the phrases can create not very convincing relations such as Russian church - Russian language. It is explainable but does not seem much topical in this case.\nThe thesaurus topics seem to convey the contents in the most concentrated way. In the Syrian topic general word country is absent; instead of UN (United Nations), it contains word rebel, which is closer to the Syrian situation. In the Orthodox church topic, the unigram variant contains extra word year, relations of words Moscow and Kirill to other words in the topic can be inferred only from the encyclopedic knowledge.\nAlso for each model kernels, we calculated the average number of known relations between topics’s elements: thesaurus relations (synonyms and direct relations between concepts) and component-based relations between phrases (Relc). It can be seen that if we add phrases without accounting component similarity (Runs 2, 3), the quality of topics decreases: the more phrases are added, the more the quality degrades.",

It included philosophers such as Baruch Spinoza, David Hume, John Locke, Edward Gibbon, Voltaire, Jean-Jacques Rousseau, Denis Diderot, Pierre Bayle and Isaac Newton. This movement is influenced by the scientific revolution in southern Europe arising directly from the Italian renaissance with people like Galileo Galilei. Over time it came to mean the Siècle des Lumières, in English the Age of Enlightenment.[Note 1]\n\nMembers of the movement saw themselves as a progressive élite, and battled against religious and political persecution, fighting against what they saw as the irrationality, arbitrariness, obscurantism and superstition of the previous centuries. They redefined the study of knowledge to fit the ethics and aesthetics of their time. Their works had great influence at the end of the 18th century, in the American Declaration of Independence and the French Revolution.\n\nThis intellectual and cultural renewal by the Lumières movement was, in its strictest sense, limited to Europe. These ideas were well understood in Europe, but beyond France the idea of \"enlightenment\" had generally meant a light from outside, whereas in France it meant a light coming from within oneself.\n\nIn the most general terms, in science and philosophy, the Enlightenment aimed for the triumph of reason over faith and belief; in politics and economics, the triumph of the bourgeois over nobility and clergy.",

As such, BERT-QC is the first model to achieve strong performance across more than one question classification dataset.\nTREC question classification is divided into separate coarse and fine-grained tasks centered around inferring the expected answer types of short open-domain factoid questions. TREC-6 includes 6 coarse question classes (abbreviation, entity, description, human, location, numeric), while TREC-50 expands these into 50 more fine-grained types. TREC question classification methods can be divided into those that learn the question classification task, and those that make use of either hand-crafted or semi-automated syntactic or semantic extraction rules to infer question classes. To date, the best reported accuracy for learned methods is 98.0% by Xia et al. BIBREF8 for TREC-6, and 91.6% by Van-tu et al. BIBREF24 for TREC-50. Madabushi et al.

        "evidence": "Pre-trained models BIBREF0, BIBREF1 have received much of attention recently thanks to their impressive results in many down stream NLP tasks. Additionally, multilingual pre-trained models enable many NLP applications for other languages via zero-short cross-lingual transfer. Zero-shot cross-lingual transfer has shown promising results for rapidly building applications for low resource languages. BIBREF2 show the potential of multilingual-BERT BIBREF0 in zero-shot transfer for a large number of languages from different language families on five NLP tasks, namely, natural language inference, document classification, named entity recognition, part-of-speech tagging, and dependency parsing.\nAlthough multilingual models are an important ingredient for enhancing language technology in many languages, recent research on improving pre-trained models puts much emphasis on English BIBREF3, BIBREF4, BIBREF5. The current state of affairs makes it difficult to translate advancements in pre-training from English to non-English languages. To our best knowledge, there are only three available multilingual pre-trained models to date: (1) the multilingual-BERT (mBERT) that supports 104 languages, (2) cross-lingual language model BIBREF6 that supports 100 languages, and (3) Language Agnostic SEntence Representations BIBREF7 that supports 93 languages. Among the three models, LASER is based on neural machine translation approach and strictly requires parallel data to train.\nDo multilingual models always need to be trained from scratch? Can we transfer linguistic knowledge learned by English pre-trained models to other languages? In this work, we develop a technique to rapidly transfer an existing pre-trained model from English to other languages in an energy efficient way BIBREF8. As the first step, we focus on building a bilingual language model (LM) of English and a target language. Starting from a pre-trained English LM, we learn the target language specific parameters (i.e., word embeddings), while keeping the encoder layers of the pre-trained English LM fixed. We then fine-tune both English and target model to obtain the bilingual LM. We apply our approach to autoencoding language models with masked language model objective and show the advantage of the proposed approach in zero-shot transfer. Our main contributions in this work are:\nWe propose a fast adaptation method for obtaining a bilingual BERT$_{\\textsc {base}}$ of English and a target language within a day using one Tesla V100 16GB GPU.\nWe evaluate our bilingual LMs for six languages on two zero-shot cross-lingual transfer tasks, namely natural language inference BIBREF9 and universal dependency parsing.

We applied the MinMax-Dotplotting (MMD) approach proposed by Ye et al. BIBREF24 . We ran the executable program provided by the authors.\nTextTiling w/ tf INLINEFORM0 idf features. We implemented TextTiling ourselves according to BIBREF12 .\nWe tuned the hyperparameter INLINEFORM0 in Equation ()on the validation set to make the number of segmentation close to that of manual annotation, and reported precision, recall, and the F-score on the test set in Table TABREF18 . As seen, our approach significantly outperforms baselines by a large margin in terms of both precision and recall. Besides, we can see that MMD obtains low performance, which is mainly because the approach cannot be easily adapted to other datasets like short sentences of conversation utterances. In summary, we achieve an INLINEFORM1 -score higher than baseline methods by more than 20%, showing the effectiveness of enhancing TextTiling with modern word embeddings.\nWe further conducted in-depth analysis of different strategies of training word-embeddings and matching heuristics in Table TABREF21 . For word embeddings, we trained them on the 3M-sentence dataset with three strategies: (1) virtual-sentence context proposed in our paper; (2) within-sentence context, where all words (except the current one) within a sentence (either a query or reply) are regarded as the context; (3) window-based context, which is the original form of BIBREF25 : the context is the words in a window (previous 2 words and future 2 words in the sentence). We observe that our virtual-sentence strategy consistently outperforms the other two in all three matching heuristics. The results suggest that combining a query and a reply does provide more information in learning dialogue-specific word embeddings.\nRegarding matching heuristics, we find that in the second and third strategies of training word embeddings, the complicated heuristic-max method yields higher INLINEFORM0 -scores than simple sum pooling by 2–3%. However, for the virtual-sentence strategy, heuristic-max is slightly worse than the sum pooling. (The degradation is only 0.1% and not significant.) This is probably because both heuristic-max and virtual sentences emphasize the rich interaction between a query and its corresponding reply; combining them does not result in further gain.\nWe also notice that heuristic-avg is worse than other similarity measures. As this method is mathematically equivalent to the average of word-by-word similarity, it may have an undesirable blurring effect.\nTo sum up, our experiments show that both the proposed embedding learning approach and the similarity heuristic are effective for session segmentation. The embedding-enhanced TextTiling approach largely outperforms baselines.\nWe conducted an external experiment to show the effect of session segmentation in dialogue systems. We integrated the segmentation mechanism into a state-of-the-practice retrieval-based system and evaluated the results by manual annotation, similar to our previous work BIBREF27 , BIBREF31 , BIBREF32 .\nConcretely, we compared our session segmentation with fixed-length context, used in BIBREF11 . That is to say, the competing method always regards two previous utterances as context. We hired three workers to annotate the results with three integer scores (0–2 points, indicating bad, borderline, and good replies, respectively.) We sampled 30 queries from the test set of 100 sessions. For each query, we retrieved 10 candidates and computed p@1 and nDCG scores BIBREF33 (averaged over three annotators). Provided with previous utterances as context, each worker had up to 1000 sentences to read during annotation.\nTable TABREF26 presents the results of the dialogue system with session segmentation. As demonstrated, our method outperforms the simple fixed-context approach in terms of both metrics. We computed the inner-annotator agreement: std INLINEFORM0 0.309; 3-discrete-class Fleiss' kappa score INLINEFORM1 0.411, indicating moderate agreement BIBREF34 .\nCase Study. We present a case study on our website: https://sites.google.com/site/sessionsegmentation/. From the case study, we see that the proposed approach is able to segment the dialogue session appropriately, so as to better utilize background information from a conversation session.\nIn this paper, we addressed the problem of session segmentation for open-domain dialogue systems. We proposed an embedding-enhanced TextTiling approach, where we trained embeddings with the novel notion of virtual sentences; we also proposed several heuristics for similarity measure. Experimental results show that both our embedding learning and similarity measuring are effective in session segmentation, and that with our approach, we can improve the performance of a retrieval-based dialogue system.\nWe thank anonymous reviewers for useful comments and Jingbo Zhu for sharing the MMD executable program.

        "evidence": "Recently, neural machine translation (NMT) has gained popularity in the field of machine translation. The conventional encoder-decoder NMT proposed by Cho2014 uses two recurrent neural networks (RNN): one is an encoder, which encodes a source sequence into a fixed-length vector, and the other is a decoder, which decodes the vector into a target sequence. A newly proposed attention-based NMT by DzmitryBahdana2014 can predict output words using the weights of each hidden state of the encoder by the attention mechanism, improving the adequacy of translation.\nEven with the success of attention-based models, a number of open questions remain in NMT. Tu2016 argued two of the common problems are over-translation: some words are repeatedly translated unnecessary and under-translation: some words are mistakenly untranslated. This is due to the fact that NMT can not completely convert the information from the source sentence to the target sentence. Mi2016a and Feng2016 pointed out that NMT lacks the notion of coverage vector in phrase-based statistical machine translation (PBSMT), so unless otherwise specified, there is no way to prevent missing translations.\nAnother problem in NMT is an objective function. NMT is optimized by cross-entropy; therefore, it does not directly maximize the translation accuracy. Shen2016 pointed out that optimization by cross-entropy is not appropriate and proposed a method of optimization based on a translation accuracy score, such as expected BLEU, which led to improvement of translation accuracy. However, BLEU is an evaluation metric based on n-gram precision; therefore, repetition of some words may be present in the translation even though the BLEU score is improved.\nTo address to problem of repeating and missing words in the translation, tu2016neural introduce an encoder-decoder-reconstructor framework that optimizes NMT by back-translation from the output sentences into the original source sentences. In their method, after training the forward translation in a manner similar to the conventional attention-based NMT, they train a back-translation model from the hidden state of the decoder into the source sequence by a new decoder to enforce agreement between source and target sentences.\nIn order to confirm the language independence of the framework, we experiment on two parallel corpora of English-Japanese and Japanese-English translation tasks using encode-decoder-reconstructor. Our experiments show that their method offers significant improvement in BLEU scores and alleviates the problem of repeating and missing words in the translation on English-Japanese translation task, though the difference is not significant on Japanese-English translation task.\nIn addition, we jointly train a model of forward translation and back-translation without pre-training, and then evaluate this model. As a result, the encoder-decoder-reconstructor can not be trained well without pre-training, so it proves that we have to train the forward translation model in a manner similar to the conventional attention-based NMT as pre-training.\nThe main contributions of this paper are as follows:\nThe main contributions of this paper are as follows: • Experimental results show that encodedecoder-reconstructor framework achieves significant improvements in BLEU scores (1.0-1.4) for English-Japanese translation task. • Experimental results show that encodedecoder-reconstructor framework has to train the forward translation model in a manner similar to the conventional attention-based NMT as pre-training.",

In this way, overall social utility is maximized in the sense that the optimal level of voter happiness will be achieved. Ranked voting will give centrist and more moderate candidates and parties a greater chance to succeed in elections, reducing the power of the extreme elements on both sides of the political spectrum. It will encourage more moderate candidates to step forward and more moderate third parties to form. The extreme partisanship currently existing in politics will be mitigated. Donald Trump would likely not have won the Republican presidential nomination in 2016 because, although he had a very committed backing of a large minority of Republican voters, he faced a divided field of more moderate and traditional candidates who split the more rational majority of the party. Trump would likely not have been the second choice for many of the backers of other candidates. A more moderate candidate would likely have emerged as the eventual nominee.

We will keep your comments in mind and carefully revise the notations of node types in alternative ways for better presentation in our final revision.\nMeanwhile, we here reiterate our notations below for you: The key concept of our method is to generate an ego network for the minor class using two nodes: vminor and vtarget. Node features of these two nodes are mixed to determine a central node of the ego network via convex combination. vminor is the node sampled from the minor class to be augmented (oversampled). That is, the central node of a synthesized ego network acquires an identical label of vminor. On the other hand, there is no restriction for vtarget: vtarget is sampled from the entire class and exploited to synthesize the ego network of generated/augmented node. Thus, the target node vtarget does not have to be a minor node. Detailed justification of this strategy for target node selection is discussed in Section 5.2 and our answers to Q2 below.",
        "evidence": "Our method utilizes the target node vtarget from all classes, not only from the identical minor class of vminor. The intention of constructing the target node pool from entire classes is to guarantee sufficient diversity of synthesized ego networks. If the target nodes are restricted to a minor class at highly imbalanced scenarios, identical neighbor nodes would be redundantly duplicated. This issue makes it hard to mitigate the neighbor memorization problem. To demonstrate this hypothesis, we conduct an experiment and compare our design choice (all classes) to select a target from the identical class as the minor node vminor. In the Figure 3, we confirm that exploiting entire classes for the target node achieves superior performances. From this design choice of the target node, our method can utilize the manifold assumption that ‘similar predictions of neural networks indicate the close proximity in the manifold’, which are commonly utilized in semi-supervised learning (Van Engelen & Hoos, 2020). We aim to enlarge and smooth the decision boundary of the minor class by interpolating the minor nodes and the target node of the entire classes (but excluding target-specific attributes using saliency) as investigated in Verma et al. (2019). Moreover, our method considers the prediction of the ego network (not a single node) to reflect the structural aspects of graph.",

        "answer": "They want to find a solution that generalizes in this linguistic sense.",
        "evidence": "It is well known that language has certain structural properties which allows natural language speakers to make “infinite use of finite means\" BIBREF3 . This structure allows us to generalize beyond the typical machine learning definition of generalization BIBREF4 (which considers performance on the distribution that generated the training set), permitting the understanding of any utterance sharing the same structure, regardless of probability. For example, sentences of length 100 typically do not appear in natural text or speech (our personal 'training set'), but can be understood regardless due to their structure. We refer to this notion as linguistic generalization .\nMany problems in NLP are treated as sequence to sequence tasks with solutions built on seq2seq-attention based models. While these models perform very well on standard datasets and also appear to capture some linguistic structure BIBREF5 , BIBREF6 , BIBREF7 , they also can be quite brittle, typically breaking on uncharacteristic inputs BIBREF8 , BIBREF1 , indicating that the extent of linguistic generalization these models achieve is still somewhat lacking.\nDue to the high capacity of these models, it is not unreasonable to expect them to learn some structure from the data. However, learning structure is not a sufficient condition to achieving linguistic generalization. If this structure is to be usable on data outside the training distribution, the model must learn the structure without additionally learning (overfitting on) patterns specific to the training data. One may hope, given the right hyperparameter configuration and regularization, that a model converges to a solution that captures the reusable structure without overfitting too much on the training set. While this solution exists in theory, in practice, it may be difficult to find.\nIn this work, we look at the feasibility of training and tuning seq2seq-attention models towards a solution that generalizes in this linguistic sense. In particular, we train models on a symbol replacement task with a well defined generalizable structure. The task is simple enough that all models achieve near perfect accuracy on the standard test set, i.e., where the inputs are drawn from the same distribution as that of the training set. We then test these models for linguistic generalization by creating test sets of uncharacteristic inputs, i.e., inputs that are not typical in the training distribution but still solvable given that the generalizable structure was learned. Our results indicate that generalization is highly sensitive; such that even changes in the random seed can drastically affect the ability to generalize. This dependence on an element that is not (or ideally should not be) a hyperparameter suggests that the line between generalization and failure is quite fine, and may not be feasible to reach simply by hyperparameter tuning alone.\nIn this work, we look at the feasibility of training and tuning seq2seq-attention models towards a solution that generalizes in this linguistic sense.",

        "answer": "The experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.",
        "evidence": "With the rapid growth of the internet, huge amounts of text data are generated in social networks, online shopping and news websites, etc. These data create demand for powerful and efficient text analysis techniques. Probabilistic topic models such as Latent Dirichlet Allocation (LDA) BIBREF0 are popular approaches for this task, by discovering latent topics from text collections. Many conventional topic models discover topics purely based on the word-occurrences, ignoring the meta information (a.k.a., side information) associated with the content. In contrast, when we humans read text it is natural to leverage meta information to improve our comprehension, which includes categories, authors, timestamps, the semantic meanings of the words, etc. Therefore, topic models capable of using meta information should yield improved modelling accuracy and topic quality.\nIn practice, various kinds of meta information are available at the document level and the word level in many corpora. At the document level, labels of documents can be used to guide topic learning so that more meaningful topics can be discovered. Moreover, it is highly likely that documents with common labels discuss similar topics, which could further result in similar topic distributions. For example, if we use authors as labels for scientific papers, the topics of the papers published by the same researcher can be closely related.\nAt the word level, different semantic/syntactic features are also accessible. For example, there are features regarding word relationships, such as synonyms obtained from WordNet BIBREF1 , word co-occurrence patterns obtained from a large corpus, and linked concepts from knowledge graphs. It is preferable that words having similar meaning but different morphological forms, like “dog” and “puppy”, are assigned to the same topic, even if they barely co-occur in the modelled corpus. Recently, word embeddings generated by GloVe BIBREF2 and word2vec BIBREF3 , have attracted a lot of attention in natural language processing and related fields. It has been shown that the word embeddings can capture both the semantic and syntactic features of words so that similar words are close to each other in the embedding space. It seems reasonable to expect that these word embedding will improve topic modelling BIBREF4 , BIBREF5 .\nConventional topic models can suffer from a large performance degradation over short texts (e.g., tweets and news headlines) because of insufficient word co-occurrence information. In such cases, meta information of documents and words can play an important role in analysing short texts by compensating the lost information in word co-occurrences. At the document level, for example, tweets are usually associated with hashtags, users, locations, and timestamps, which can be used to alleviate the data sparsity problem. At the word level, word semantic similarity and embeddings obtained or trained on large external corpus (e.g., Google News or Wikipedia) have been proven useful in learning meaningful topics from short texts BIBREF6 , BIBREF7 .\nThe benefit of using document and word meta information separately is shown in several models such as BIBREF8 , BIBREF9 , BIBREF5 . However, in existing models this is usually not efficient enough due to non-conjugacy and/or complex model structures. Moreover, only one kind of meta information (either at document level or at word level) is used in most existing models. In this paper, we propose MetaLDA, a topic model that can effectively and efficiently leverage arbitrary document and word meta information encoded in binary form. Specifically, the labels of a document in MetaLDA are incorporated in the prior of the per-document topic distributions. If two documents have similar labels, their topic distributions should be generated with similar Dirichlet priors. Analogously, at the word level, the features of a word are incorporated in the prior of the per-topic word distributions, which encourages words with similar features to have similar weights across topics. Therefore, both document and word meta information, if and when they are available, can be flexibly and simultaneously incorporated using MetaLDA. MetaLDA has the following key properties:\nWe conduct extensive experiments with several real datasets including regular and short texts in various domains. The experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.\nThe experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.",

To further improve the performance, we optimize the pre-training process of BERT by introducing a semantic-enhanced task.\nOriginal google BERT is pre-trained using two unsupervised tasks, masked language model (MLM) and next sentence prediction (NSP). MLM task enables the model to capture the discriminative contextual feature. NSP task makes it possible to understand the relationship between sentence pairs, which is not directly captured by language modeling. We further design a semantic-enhanced task to enhance the performance of BERT. It incorporate previous sentence prediction and document level prediction.

        "question": "Is the new system better than today's status quo approach?",
        "answer": "Yes.",
        "evidence": "What would be possible if a person had an oracle that could immediately provide the answer to any question about the visual world? Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach.",

The technology to move and assemble the massive stones of the Stonehenge has been shown to be available to humans at that time. Second, given that space is vast the chance of finding one tiny planet among billions is infinitesimal. If alien intelligence had indeed found our one inhabited planet they are unlikely to have just created couple of structures and avoided any further contact with Earth and its inhabitants.

        "evidence": "Negotiations, either between individuals or entities, are ubiquitous in everyday human interactions ranging from sales to legal proceedings. Being a good negotiator is a complex skill, requiring the ability to understand the partner's motives, ability to reason and to communicate effectively, making it a challenging task for an automated system. While research in building automatically negotiating agents has primarily focused on agent-agent negotiations BIBREF0, BIBREF1, there is a recent interest in agent-human negotiations BIBREF2 as well. Such agents may act as mediators or can be helpful for pedagogical purposes BIBREF3.\nEfforts in agent-human negotiations involving free-form natural language as a means of communication are rather sparse. Researchers BIBREF4 recently studied natural language negotiations in buyer-seller bargaining setup, which is comparatively less restricted than previously studied game environments BIBREF5, BIBREF6. Lack of a well-defined structure in such negotiations allows humans or agents to express themselves more freely, which better emulates a realistic scenario. Interestingly, this also provides an exciting research opportunity: how can an agent leverage the behavioral cues in natural language to direct its negotiation strategies? Understanding the impact of natural language on negotiation outcomes through a data-driven neural framework is the primary objective of this work.\nWe focus on buyer-seller negotiations BIBREF4 where two individuals negotiate the price of a given product. Leveraging the recent advancements BIBREF7, BIBREF8 in pre-trained language encoders, we attempt to predict negotiation outcomes early on in the conversation, in a completely data-driven manner (Figure FIGREF3). Early prediction of outcomes is essential for effective planning of an automatically negotiating agent. Although there have been attempts to gain insights into negotiations BIBREF9, BIBREF10, to the best of our knowledge, we are the first to study early natural language cues through a data-driven neural system (Section SECREF3). Our evaluations show that natural language allows the models to make better predictions by looking at only a fraction of the negotiation. Rather than just realizing the strategy in natural language, our empirical results suggest that language can be crucial in the planning as well. We provide a sample negotiation from the test set BIBREF4 along with our model predictions in Table TABREF1.\nWe design ablation studies and a probing technique for BERT to pinpoint which linguistic features help more than others for early outcome prediction task.",

        "evidence": "Online social networks have become one of the most disruptive communication platforms, as everyday billions of individuals use them to interact with each other. Their penetration in our everyday lives seems ever-growing and has in turn generated a massive volume of publicly available data open to analysis. The digital footprints left across these multiple media platforms provide us with a unique source to study and understand how the linguistic phenotype of a given user is related to social attributes such as socioeconomic status (SES).\nThe quantification and inference of SES of individuals is a long lasting question in the social sciences. It is a rather difficult problem as it may depend on a combination of individual characteristics and environmental variables BIBREF0 . Some of these features can be easier to assess like income, gender, or age whereas others, relying to some degree on self-definition and sometimes entangled with privacy issues, are harder to assign like ethnicity, occupation, education level or home location. Furthermore, individual SES correlates with other individual or network attributes, as users tend to build social links with others of similar SES, a phenomenon known as status homophily BIBREF1 , arguably driving the observed stratification of society BIBREF2 . At the same time, shared social environment, similar education level, and social influence have been shown to jointly lead socioeconomic groups to exhibit stereotypical behavioral patterns, such as shared political opinion BIBREF3 or similar linguistic patterns BIBREF4 . Although these features are entangled and causal relation between them is far from understood, they appear as correlations in the data.\nDatasets recording multiple characteristics of human behaviour are more and more available due to recent developments in data collection technologies and increasingly popular online platforms and personal digital devices. The automatic tracking of online activities, commonly associated with profile data and meta-information; the precise recording of daily activities, interaction dynamics and mobility patterns collected through mobile personal devices; together with the detailed and expert annotated census data all provide new grounds for the inference of individual features or behavioral patterns BIBREF5 . The exploitation of these data sources has already been proven to be fruitful as cutting edge recommendation systems, advanced methods for health record analysis, or successful prediction tools for social behaviour heavily rely on them BIBREF6 . Nevertheless, despite the available data, some inference tasks, like individual SES prediction, remain an open challenge.\nThe precise inference of SES would contribute to overcome several scientific challenges and could potentially have several commercial applications BIBREF7 . Further, robust SES inference would provide unique opportunities to gain deeper insights on socioeconomic inequalities BIBREF8 , social stratification BIBREF2 , and on the driving mechanisms of network evolution, such as status homophily or social segregation.\nIn this work, we take a horizontal approach to this problem and explore various ways to infer the SES of a large sample of social media users. We propose different data collection and combination strategies using open, crawlable, or expert annotated socioeconomic data for the prediction task. Specifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations. Individual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations. Each of these datasets is then used as ground-truth to infer the SES of Twitter users from profile and semantic features similar to BIBREF9 . We aim to explore and assess how the SES of social media users can be obtained and how much the inference problem depends on annotation and the user's individual and linguistic attributes.\nWe provide in Section SECREF2 an overview of the related literature to contextualize the novelty of our work. In Section SECREF3 we provide a detailed description of the data collection and combination methods. In Section SECREF4 we introduce the features extracted to solve the SES inference problem, with results summarized in Section SECREF5 . Finally, in Section SECREF6 and SECREF7 we conclude our paper with a brief discussion of the limitations and perspectives of our methods.\nWe aim to explore and assess how the SES of social media users can be obtained and how much the inference problem depends on annotation and the user's individual and linguistic attributes.",

It has attracted much attention recently as it could make texts more accessible to wider audiences, and used as a pre-processing step, improve performances of various NLP tasks and systems BIBREF13 , BIBREF14 , BIBREF15 . Usually, hand-crafted, supervised, and unsupervised methods based on resources like English Wikipedia and Simple English Wikipedia (EW-SEW) BIBREF10 are utilized for extracting simplification rules. It is very easy to mix up the automatic TS task and the automatic summarization task BIBREF3 , BIBREF16 , BIBREF6 . TS is different from text summarization as the focus of text summarization is to reduce the length and redundant content.\nAt the lexical level, lexical simplification systems often substitute difficult words using more common words, which only require a large corpus of regular text to obtain word embeddings to get words similar to the complex word BIBREF1 , BIBREF9 . Biran et al. BIBREF0 adopted an unsupervised method for learning pairs of complex and simpler synonyms from a corpus consisting of Wikipedia and Simple Wikipedia. At the sentence level, a sentence simplification model was proposed by tree transformation based on statistical machine translation (SMT) BIBREF3 . Woodsend and Lapata BIBREF17 presented a data-driven model based on a quasi-synchronous grammar, a formalism that can naturally capture structural mismatches and complex rewrite operations. Wubben et al. BIBREF18 proposed a phrase-based machine translation (PBMT) model that is trained on ordinary-simplified sentence pairs. Xu et al. BIBREF19 proposed a syntax-based machine translation model using simplification-specific objective functions and features to encourage simpler output.\nCompared with SMT, neural machine translation (NMT) has shown to produce state-of-the-art results BIBREF5 , BIBREF7 . The central approach of NMT is an encoder-decoder architecture implemented by recurrent neural networks, which can represent the input sequence as a vector, and then decode that vector into an output sequence. Therefore, NMT models were used for text simplification task, and achieved good results BIBREF8 , BIBREF4 , BIBREF20 . The main limitation of the aforementioned NMT models for text simplification depended on the parallel ordinary-simplified sentence pairs. Because ordinary-simplified sentence pairs are expensive and time-consuming to build, the available largest data is EW-SEW that only have 296,402 sentence pairs. The dataset is insufficiency for NMT model if we want to NMT model can obtain the best parameters. Considering simplified data plays an important role in boosting fluency for phrase-based text simplification, and we investigate the use of simplified data for text simplification. We are the first to show that we can effectively adapt neural translation models for text simplifiation with simplified corpora.\nCompared with SMT, neural machine translation (NMT) has shown to produce state-of-the-art results (Bahdanau et al., 2014; Sutskever et al., 2014).",

The Mets won the series four games to three to claim their second World Series title and first since 1969. The series is best remembered for its Game 6, which saw the Mets rally from a two run-deficit in the bottom of the 10th inning, despite having two outs and no one on base. The Red Sox, who held a 3–2 series lead, were twice one strike away from securing the championship, but failed to close out the inning as the Mets won off an error by Boston first baseman Bill Buckner.

        "answer": "The author propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network.",
        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network.",

I can live my life according to my wish and do not have to follow the rules and restrictions of society. I can now live the “Hakuna Matata” life without worrying about my future temporarily. Alas!

The availability of multilingual pre-trained models enables zero-shot transfer of NLP tasks from high resource languages to low resource ones. However, recent research in improving pre-trained models focuses heavily on English. While it is possible to train the latest neural architectures for other languages from scratch, it is undesirable due to the required amount of compute. In this work, we tackle the problem of transferring an existing pre-trained model from English to other languages under a limited computational budget. With a single GPU, our approach can obtain a foreign BERT base model within a day and a foreign BERT large within two days. Furthermore, evaluating our models on six languages, we demonstrate that our models are better than multilingual BERT on two zero-shot tasks: natural language inference and dependency parsing.\nIn this work, we tackle the problem of transferring an existing pretrained model from English to other languages under a limited computational budget.",

Second (Bottleneck B2), they address only one topic of cyberbullying such as racism, and sexism.Third (Bottleneck B3), they rely on carefully handcrafted features such as swear word list and POS tagging.",
        "evidence": "Cyberbullying has been defined by the National Crime Prevention Council as the use of the Internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person. Various studies have estimated that between to 10% to 40% of internet users are victims of cyberbullying BIBREF0 . Effects of cyberbullying can range from temporary anxiety to suicide BIBREF1 . Many high profile incidents have emphasized the prevalence of cyberbullying on social media. Most recently in October 2017, a Swedish model Arvida Byström was cyberbullied to the extent of receiving rape threats after she appeared in an advertisement with hairy legs.\nDetection of cyberbullying in social media is a challenging task. Definition of what constitutes cyberbullying is quite subjective. For example, frequent use of swear words might be considered as bullying by the general population. However, for teen oriented social media platforms such as Formspring, this does not necessarily mean bullying (Table TABREF9 ). Across multiple SMPs, cyberbullies attack victims on different topics such as race, religion, and gender. Depending on the topic of cyberbullying, vocabulary and perceived meaning of words vary significantly across SMPs. For example, in our experiments we found that for word `fat', the most similar words as per Twitter dataset are `female' and `woman' (Table TABREF23 ). However, other two datasets do not show such particular bias against women. This platform specific semantic similarity between words is a key aspect of cyberbullying detection across SMPs. Style of communication varies significantly across SMPs. For example, Twitter posts are short and lack anonymity. Whereas posts on Q&A oriented SMPs are long and have option of anonymity (Table TABREF7 ). Fast evolving words and hashtags in social media make it difficult to detect cyberbullying using swear word list based simple filtering approaches. The option of anonymity in certain social networks also makes it harder to identify cyberbullying as profile and history of the bully might not be available.\nPast works on cyberbullying detection have at least one of the following three bottlenecks. First (Bottleneck B1), they target only one particular social media platform. How these methods perform across other SMPs is unknown. Second (Bottleneck B2), they address only one topic of cyberbullying such as racism, and sexism. Depending on the topic, vocabulary and nature of cyberbullying changes. These models are not flexible in accommodating changes in the definition of cyberbullying. Third (Bottleneck B3), they rely on carefully handcrafted features such as swear word list and POS tagging. However, these handcrafted features are not robust against variations in writing style. In contrast to existing bottlenecks, this work targets three different types of social networks (Formspring: a Q&A forum, Twitter: microblogging, and Wikipedia: collaborative knowledge repository) for three topics of cyberbullying (personal attack, racism, and sexism) without doing any explicit feature engineering by developing deep learning based models along with transfer learning.\nWe experimented with diverse traditional machine learning models (logistic regression, support vector machine, random forest, naive Bayes) and deep neural network models (CNN, LSTM, BLSTM, BLSTM with Attention) using variety of representation methods for words (bag of character n-gram, bag of word unigram, GloVe embeddings, SSWE embeddings). Summary of our findings and research contributions is as follows.\nFirst (Bottleneck B1), they target only one particular social media platform. How these methods perform across other SMPs is unknown. Second (Bottleneck B2), they address only one topic of cyberbullying such as racism, and sexism.

The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. An organism's phenotype results from two basic factors: the expression of an organism's genetic code (its genotype) and the influence of environmental factors. Both factors may interact, further affecting the phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and then again in his 1982 book The Extended Phenotype suggested that one can regard bird nests and other built structures such as caddisfly larva cases and beaver dams as \"extended phenotypes\".\n\nWilhelm Johannsen proposed the genotype–phenotype distinction in 1911 to make clear the difference between an organism's hereditary material and what that hereditary material produces. The distinction resembles that proposed by August Weismann (1834–1914), who distinguished between germ plasm (heredity) and somatic cells (the body). More recently, in The Selfish Gene (1976), Dawkins distinguished these concepts as replicators and vehicles.\n\nThe genotype–phenotype distinction should not be confused with Francis Crick's central dogma of molecular biology, a statement about the directionality of molecular sequential information flowing from DNA to protein, and not the reverse.",

Political scientists have created many typologies describing variations of authoritarian forms of government. Authoritarian regimes may be either autocratic or oligarchic and may be based upon the rule of a party or the military. States that have a blurred boundary between democracy and authoritarianism have some times been characterized as \"hybrid democracies\", \"hybrid regimes\" or \"competitive authoritarian\" states.\n\nThe political scientist Juan Linz, in an influential 1964 work, An Authoritarian Regime: Spain, defined authoritarianism as possessing four qualities:\n\nLimited political pluralism, is realized with constraints on the legislature, political parties and interest groups.\nPolitical legitimacy is based upon appeals to emotion and identification of the regime as a necessary evil to combat \"easily recognizable societal problems, such as underdevelopment or insurgency.\"\nMinimal political mobilization, and suppression of anti-regime activities.\nIll-defined executive powers, often vague and shifting extend the power of the executive.\nMinimally defined, an authoritarian government lacks free and competitive direct elections to legislatures, free and competitive direct or indirect elections for executives, or both. Broadly defined, authoritarian states include countries that lack civil liberties such as freedom of religion, or countries in which the government and the opposition do not alternate in power at least once following free elections. Authoritarian states might contain nominally democratic institutions such as political parties, legislatures and elections which are managed to entrench authoritarian rule and can feature fraudulent, non-competitive elections. In contexts of democratic backsliding, scholars tend to identify authoritarian political leaders based on certain tactics, such as: politicizing independent institutions, spreading disinformation, aggrandizing executive power, quashing dissent, targeting vulnerable communities, stoking violence, and corrupting elections.

        "evidence": "Topic models (e.g., LDA BIBREF47 ) are usually unsupervised and therefore less biased towards human-defined categories. They are especially suited for insight-driven analysis, because they are constrained in ways that make their output interpretable. Although there is no guarantee that a “topic” will correspond to a recognizable theme or event or discourse, they often do so in ways that other methods do not. Their easy applicability without supervision and ready interpretability make topic models good for exploration. Topic models are less successful for many performance-driven applications. Raw word features are almost always better than topics for search and document classification. LSTMs and other neural network models are better as language models. Continuous word embeddings have more expressive power to represent fine-grained semantic similarities between words.\nA topic model provides a different perspective on a collection. It creates a set of probability distributions over the vocabulary of the collection, which, when combined together in different proportions, best match the content of the collection. We can sort the words in each of these distributions in descending order by probability, take some arbitrary number of most-probable words, and get a sense of what (if anything) the topic is “about”. Each of the text segments also has its own distribution over the topics, and we can sort these segments by their probability within a given topic to get a sense of how that topic is used.\nOne of the most common questions about topic models is how many topics to use, usually with the implicit assumption that there is a “right” number that is inherent in the collection. We prefer to think of this parameter as more like the scale of a map or the magnification of a microscope. The “right” number is determined by the needs of the user, not by the collection. If the analyst is looking for a broad overview, a relatively small number of topics may be best. If the analyst is looking for fine-grained phenomena, a larger number is better.\nAfter fitting the model, it may be necessary to circle back to an earlier phase. Topic models find consistent patterns. When authors repeatedly use a particular theme or discourse, that repetition creates a consistent pattern. But other factors can also create similar patterns, which look as good to the algorithm. We might notice a topic that has highest probability on French stopwords, indicating that we need to do a better job of filtering by language. We might notice a topic of word fragments, such as “ing”, “tion”, “inter”, indicating that we are not handling end-of-line hyphenation correctly. We may need to add to our stoplist or change how we curate multi-word terms.\nTopic models (e.g., LDA [Blei et al., 2003]) are usually unsupervised and therefore less biased towards human-defined categories.

The 16th and final ranking event of the 2021–22 snooker season, the tournament was organised by the World Snooker Tour and sponsored by sports betting company Betfred. It was broadcast in the United Kingdom by the BBC, in Europe (including the UK) by Eurosport, and elsewhere in the world by Matchroom Sport and other broadcasters. The total prize fund was £2,395,000, of which the winner received £500,000.\n\nQualifying rounds for the tournament took place from 4 to 13 April 2022 at the English Institute of Sport, featuring 128 professional and invited amateur players. The main stage of the tournament featured 32 players: the top 16 players from the snooker world rankings and another 16 players from the qualifying rounds. Ashley Hugill, Jackson Page, and Hossein Vafaei were debutants at the Crucible, Vafaei being the first Iranian player to reach the main stage. Mark Selby was the defending champion, having won the 2021 final 18–15 against Shaun Murphy. He lost 10–13 to Yan Bingtao in a second-round match that produced the longest frame ever played at the Crucible, lasting 85 minutes.\n\nRonnie O'Sullivan equalled Steve Davis's record of 30 Crucible appearances. He reached a record 20th quarter-final and a record 13th semi-final before defeating Judd Trump 18–13 in the final to equal Stephen Hendry's record of seven world titles. It was O'Sullivan's 39th ranking title and 21st Triple Crown title. Aged 46 years and 148 days, he became the oldest world champion in the sport's history, surpassing Ray Reardon, who was aged 45 years and 203 days when he won his last world title in 1978. O'Sullivan also broke Hendry's record of 70 wins at the Crucible, setting a new record of 74.\n\nNeil Robertson made a maximum break in his second-round match against Jack Lisowski, the fifth of his career and the 12th time a 147 had been achieved at the Crucible. Graeme Dott also made a maximum break in his third-round qualifying match against Pang Junxu, the second of his career and the fifth time that a maximum had been made in the World Championship qualifiers. The main stage produced a record 109 century breaks, surpassing the 108 centuries made the preceding year.

        "question": "Does the MetaLDA achieve improved performance in terms of perplexity, topic coherence, and running time?",
        "answer": "Yes, it does.",
        "evidence": "With the rapid growth of the internet, huge amounts of text data are generated in social networks, online shopping and news websites, etc. These data create demand for powerful and efficient text analysis techniques. Probabilistic topic models such as Latent Dirichlet Allocation (LDA) BIBREF0 are popular approaches for this task, by discovering latent topics from text collections. Many conventional topic models discover topics purely based on the word-occurrences, ignoring the meta information (a.k.a., side information) associated with the content. In contrast, when we humans read text it is natural to leverage meta information to improve our comprehension, which includes categories, authors, timestamps, the semantic meanings of the words, etc. Therefore, topic models capable of using meta information should yield improved modelling accuracy and topic quality.\nIn practice, various kinds of meta information are available at the document level and the word level in many corpora. At the document level, labels of documents can be used to guide topic learning so that more meaningful topics can be discovered. Moreover, it is highly likely that documents with common labels discuss similar topics, which could further result in similar topic distributions. For example, if we use authors as labels for scientific papers, the topics of the papers published by the same researcher can be closely related.\nAt the word level, different semantic/syntactic features are also accessible. For example, there are features regarding word relationships, such as synonyms obtained from WordNet BIBREF1 , word co-occurrence patterns obtained from a large corpus, and linked concepts from knowledge graphs. It is preferable that words having similar meaning but different morphological forms, like “dog” and “puppy”, are assigned to the same topic, even if they barely co-occur in the modelled corpus. Recently, word embeddings generated by GloVe BIBREF2 and word2vec BIBREF3 , have attracted a lot of attention in natural language processing and related fields. It has been shown that the word embeddings can capture both the semantic and syntactic features of words so that similar words are close to each other in the embedding space. It seems reasonable to expect that these word embedding will improve topic modelling BIBREF4 , BIBREF5 .\nConventional topic models can suffer from a large performance degradation over short texts (e.g., tweets and news headlines) because of insufficient word co-occurrence information. In such cases, meta information of documents and words can play an important role in analysing short texts by compensating the lost information in word co-occurrences. At the document level, for example, tweets are usually associated with hashtags, users, locations, and timestamps, which can be used to alleviate the data sparsity problem. At the word level, word semantic similarity and embeddings obtained or trained on large external corpus (e.g., Google News or Wikipedia) have been proven useful in learning meaningful topics from short texts BIBREF6 , BIBREF7 .\nThe benefit of using document and word meta information separately is shown in several models such as BIBREF8 , BIBREF9 , BIBREF5 . However, in existing models this is usually not efficient enough due to non-conjugacy and/or complex model structures. Moreover, only one kind of meta information (either at document level or at word level) is used in most existing models. In this paper, we propose MetaLDA, a topic model that can effectively and efficiently leverage arbitrary document and word meta information encoded in binary form. Specifically, the labels of a document in MetaLDA are incorporated in the prior of the per-document topic distributions. If two documents have similar labels, their topic distributions should be generated with similar Dirichlet priors. Analogously, at the word level, the features of a word are incorporated in the prior of the per-topic word distributions, which encourages words with similar features to have similar weights across topics. Therefore, both document and word meta information, if and when they are available, can be flexibly and simultaneously incorporated using MetaLDA. MetaLDA has the following key properties:\nWe conduct extensive experiments with several real datasets including regular and short texts in various domains. The experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.\nThe experimental results demonstrate that MetaLDA achieves improved performance in terms of perplexity, topic coherence, and running time.",

        "question": "What framework does the paper introduce?",
        "answer": "A systematic, rigorous evaluation framework to assess the quality of adversarial examples for NLP.",
        "evidence": "Adversarial examples, a term introduced in BIBREF0, are inputs transformed by small perturbations that machine learning models consistently misclassify. The experiments are conducted in the context of computer vision (CV), and the core idea is encapsulated by an illustrative example: after imperceptible noises are added to a panda image, an image classifier predicts, with high confidence, that it is a gibbon. Interestingly, these adversarial examples can also be used to improve the classifier — either as additional training data BIBREF0 or as a regularisation objective BIBREF1 — thus providing motivation for generating effective adversarial examples.\nThe germ of this paper comes from our investigation of adversarial attack methods for natural language processing (NLP) tasks, e.g. sentiment classification, which drives us to quantify what is an “effective” or “good” adversarial example. In the context of images, a good adversarial example is typically defined according two criteria:\nit has successfully fooled the classifier;\nit is visually similar to the original example.\nIn NLP, defining a good adversarial example is a little more involving, because while criterion (b) can be measured with a comparable text similarity metric (e.g. BLEU or edit distance), an adversarial example should also:\nbe fluent or natural;\npreserve its original label.\nThese two additional criteria are generally irrelevant for images, as adding minor perturbations to an image is unlikely to: (1) create an uninterpretable image (where else changing one word in a sentence can render a sentence incoherent), or (2) change how we perceive the image, say from seeing a panda to a gibbon (but a sentence's sentiment can be reversed by simply adding a negative adverb such as not). Without considering criterion (d), generating adversarial examples in NLP would be trivial, as the model can learn to simply replace a positive adjective (amazing) with a negative one (awful) to attack a sentiment classifier.\nTo the best of our knowledge, most studies on adversarial example generation in NLP have largely ignored these additional criteria BIBREF2, BIBREF3, BIBREF4, BIBREF5. We believe the lack of a rigorous evaluation framework partially explains why adversarial training for NLP models has not seen the same extent of improvement compared to CV models. As our experiments reveal, examples generated from most attacking methods are successful in fooling the classifier, but their language is often unnatural and the original label is not properly preserved.\nThe core contribution of our paper is to introduce a systematic, rigorous evaluation framework to assess the quality of adversarial examples for NLP. We focus on sentiment classification as the target task, as it is a popular application that highlights the importance of criteria discussed above. We test a number of attacking methods and also propose an alternative approach (based on an auto-encoder) for generating adversarial examples. We learn that a number of factors can influence the performance of adversarial attacks, including architecture of the classifier, sentence length and input domain.\nThe core contribution of our paper is to introduce a systematic, rigorous evaluation framework to assess the quality of adversarial examples for NLP.",

        "answer": "The authors demonstrate the effectiveness of the architectures on two kinds of NLP tasks: text classification and sequence tagging.",
        "evidence": "Deep learning models have been widely used in many natural language processing (NLP) tasks. A major challenge is how to design and learn the semantic composition function while modeling a text sequence. The typical composition models involve sequential BIBREF0 , BIBREF1 , convolutional BIBREF2 , BIBREF3 , BIBREF4 and syntactic BIBREF5 , BIBREF6 , BIBREF7 compositional models.\nIn spite of their success, these models have two major limitations. First, they usually use a shared composition function for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Second, different composition functions are learned from scratch in different tasks. However, given a certain natural language, its composition functions should be the same (on meta-knowledge level at least), even if the tasks are different.\nTo address these problems, we need to design a dynamic composition function which can vary with different positions and contexts in a sequence, and share it across the different tasks. To share some meta-knowledge of composition function, we can adopt the multi-task learning BIBREF8 . However, the sharing scheme of most neural multi-task learning methods is feature-level sharing, where a subspace of the feature space is shared across all the tasks. Although these sharing schemes are successfully used in various NLP tasks BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , they are not suitable to share the composition function.\nIn this paper, inspired by recent work on dynamic parameter generation BIBREF15 , BIBREF16 , BIBREF17 , we propose a function-level sharing scheme for multi-task learning, in which a shared meta-network is used to learn the meta-knowledge of semantic composition among the different tasks. The task-specific semantic composition function is generated by the meta-network. Then the task-specific composition function is used to obtain the task-specific representation of a text sequence. The difference between two sharing schemes is shown in Figure 1 . Specifically, we use two LSTMs as meta and basic (task-specific) network respectively. The meta LSTM is shared for all the tasks. The parameters of the basic LSTM are generated based on the current context by the meta LSTM, therefore the composition function is not only task-specific but also position-specific. The whole network is differentiable with respect to the model parameters and can be trained end-to-end.\nWe demonstrate the effectiveness of our architectures on two kinds of NLP tasks: text classification and sequence tagging. Experimental results show that jointly learning of multiple related tasks can improve the performance of each task relative to learning them independently.\nOur contributions are of three-folds:\nWe demonstrate the effectiveness of our architectures on two kinds of NLP tasks: text classification and sequence tagging.",

        "question": "Is a state-of-the-art model that learns from path-based representations of code and claimed by Common Vulnerabilities and Exposures (CVE) to be suitable for a wide range of source code classification tasks, performing better than the logistic regression baseline?",
        "answer": "No.",
        "evidence": "The use of open-source software has been steadily increasing for some time now, with the number of Java packages in Maven Central doubling in 2018. However, BIBREF0 states that there has been an 88% growth in the number of vulnerabilities reported over the last two years. In order to develop secure software, it is essential to analyze and understand security vulnerabilities that occur in software systems and address them in a timely manner. While there exist several approaches in the literature for identifying and managing security vulnerabilities, BIBREF1 show that an effective vulnerability management approach must be code-centric. Rather than relying on metadata, efforts must be based on analyzing vulnerabilities and their fixes at the code level.\nCommon Vulnerabilities and Exposures (CVE) is a list of publicly known cybersecurity vulnerabilities, each with an identification number. These entries are used in the National Vulnerability Database (NVD), the U.S. government repository of standards based vulnerability management data. The NVD suffers from poor coverage, as it contains only 10% of the open-source vulnerabilities that have received a CVE identifier BIBREF2. This could be due to the fact that a number of security vulnerabilities are discovered and fixed through informal communication between maintainers and their users in an issue tracker. To make things worse, these public databases are too slow to add vulnerabilities as they lag behind a private database such as Snyk's DB by an average of 92 days BIBREF0 All of the above pitfalls of public vulnerability management databases (such as NVD) call for a mechanism to automatically infer the presence of security threats in open-source projects, and their corresponding fixes, in a timely manner.\nWe propose a novel approach using deep learning in order to identify commits in open-source repositories that are security-relevant. We build regularized hierarchical deep learning models that encode features first at the file level, and then aggregate these file-level representations to perform the final classification. We also show that code2vec, a model that learns from path-based representations of code and claimed by BIBREF3 to be suitable for a wide range of source code classification tasks, performs worse than our logistic regression baseline.\nIn this study, we seek to answer the following research questions:\n[leftmargin=*]\nRQ1: Can we effectively identify security-relevant commits using only the commit diff? For this research question, we do not use any of the commit metadata such as the commit message or information about the author. We treat source code changes like unstructured text without using path-based representations from the abstract syntax tree.\nRQ2: Does extracting class-level features before and after the change instead of using only the commit diff improve the identification of security-relevant commits? For this research question, we test the hypothesis that the source code of the entire Java class contains more information than just the commit diff and could potentially improve the performance of our model.\nRQ3: Does exploiting path-based representations of Java source code before and after the change improve the identification of security-relevant commits? For this research question, we test whether code2vec, a state-of-the-art model that learns from path-based representations of code, performs better than our model that treats source code as unstructured text.\nRQ4: Is mining commits using regular expression matching of commit messages an effective means of data augmentation for improving the identification of security-relevant commits? Since labelling commits manually is an expensive task, it is not easy to build a dataset large enough to train deep learning models. For this research question, we explore if collecting coarse data samples using a high-precision approach is an effective way to augment the ground-truth dataset.\nThe main contributions of this paper are:\n[leftmargin=*]\nNovel hierarchical deep learning models for the identification of security-relevant commits based on either the diff or the modified source code of the Java classes.\nA comparative analysis of how various deep learning models perform across different input representations and how various regularization techniques help with the generalization of our models.\nWe envision that this work would ultimately allow for monitoring open-source repositories in real-time, in order to automatically detect security-relevant changes such as vulnerability fixes.\nWe also show that code2vec, a model that learns from path-based representations of code and claimed by Alon et al.

        "question": "Based on the text, what are the best ways for people to eat fruits?",
        "evidence": "In the US, we are fortunate to have a dizzying array of fruits that fill our grocery stores year-round. They come in all sizes, shapes, and colors, and we have all heard about the recommended five servings of fruits and vegetables a day. So, what are we eating them for? And how does the nutritional value vary between fruits? Is there any difference between whole fruits versus juice, fresh versus dried? Let’s take a look.\n\nDifferences between fruits\nJust like other foods, different fruits have different nutrient values. Generally, whole fruits are good sources of fiber while fruit juices are not. And one cup of fruit juice, even 100% fruit juice, has a lot more sugar than one piece or one serving of whole fruit. In addition, whole fruits are more satiating than juices. When meeting the recommended fruit and vegetable intake, it is better to eat them (whole) than drink them (juice). However, one should not completely avoid drinking juice — if it is 100% juice — but you should limit consumption to no more than 4 to 8 ounces a day.\n\nThe freezer section of the grocery store is often stocked with quite a variety of frozen fruits. These are often peeled and cut already (like mango), which is convenient and often less expensive than fresh fruits. Frozen fruits are usually picked and quick-frozen near the point of harvest, therefore the nutrients are well preserved. Moreover, some seasonal fruits such as blueberries are readily available in frozen form. The key to selection is to choose plain frozen fruits without added sugar.\n\nThere are a number of fruits that are available in dried form, such as raisins, apricots, and pineapple — just to name a few. They also have good nutrient values, keep for a long time, are convenient to carry around, and are high in calories, making them a favorite for hikers and campers. However, some often have sugar added in the drying process, particularly mango and pineapple. Dried cranberries almost always have sugar added, as they are naturally very tart. Even for those without added sugar, the compact volume and sweetness make it quite easy to eat a lot in one sitting, and the calories can add up quickly.\n\nSome dried fruits like raisins and apricots are also treated with sulfur dioxide to preserve freshness and color. For most people that is not a concern; however, some individuals are sensitive, especially those with asthma. Sulfur dioxide treatment is labeled on the package, so it is not difficult to avoid if necessary.\n\nWhat about buying organic?\nWe have much choice when it comes to organic and conventionally grown fruits, be they fresh, frozen, or dried. Nutritionally, there is not enough difference to choose one over the other, though consumers might choose one over another based on farming practices and environmental impact. The US has regulations on pesticide use, but some fruits tend to have more residual pesticides than others, and it is always recommended that you wash fruits thoroughly before eating.\n\nDifferences in nutritional value\nDifferent fruits are good sources of different nutrients. Citrus fruits are high in vitamin C, and other fruits are good sources of nutrients too. A few examples below:\n\nNutrient: Major functions - Good fruit sources\n\npotassium: fluid and electrolyte balance, maintaining healthy blood pressure - oranges, raspberries, bananas, cherries, pomegranates, honeydew melons, avocados\n\niron: formation of red blood cells, brain growth in children - dried apricots, raisins\n\nvitamin C: maintaining healthy immune system, wound healing, antioxidant - citrus fruits, strawberries, kiwi\n\nfolate: DNA synthesis, formation of red blood cells, early neural tube development in the fetus - oranges, mangos, avocados\n\nvitamin A: night vision, cell growth, immune function - cantaloupe\n\nBesides the above nutrients, certain fruits are also high in flavonoids. This is a diverse group of compounds, some of which are potent antioxidants that protect against oxidative damage, and may reduce the risk of certain diseases such as cardiovascular disease and diabetes. In particular, citrus fruits are high in the flavanones class of flavonoids, and blackberries, blueberries, cranberries, and cherries are high in the anthocyanidins class of flavonoids.\n\nSo, what fruits should we eat?\nAs you can see, there isn’t one fruit that has all the nutrients, so eating a variety is the key to good health. Try something new! Most adults should eat a variety of colors for about 2 cups a day. Prioritize whole fruits over juice. Eat what is in season, as it will be cheaper. And enjoy your fruits: eat mindfully to fully appreciate the smell, texture, and flavor. Bon appetit!",

They are fresher and cheaper.\n- It is ok to eat freshly frozen fruits. Pay attention to pick frozen fruits which do not have sugar added during the process\n- There is no nutritional difference between organic and non-organic fruits.

        "question": "Why did the Soviet Union collapse?",
        "evidence": "",
        "answer": "There are a multitude of reasons for the collapse of the Soviet Union.  But historians have generally narrowed it down to the following major causes:\n\nRise of ethnic nationalism in Soviet Republics:  After decades of suppressing national identities, ethnic groups began asserting their nationality and demanded greater autonomy and political power.  This resulted in numerous riots and protests throughout the Soviet Union with demands for independence and national self-determination. \n\nEconomic stagnation and fall of oil prices:  The centrally planned economic model resulted in massive shortages of staple consumer products.  Shops were continually empty and Soviet citizens needed to wait in long lines to purchase basic goods.  After years of economic deprivation, Soviet citizens were deeply angry at their government. In addition, oil prices declined significantly in the late 1980s, which provided the Soviet government a key source of hard currency.  This it made it difficult for the Soviet government to sustain high levels of military spending and keep the economy functioning. \n\nPerestroika and Glasnost: Gorbachev's reforms of the 1980s were intended to reinvigorate the Soviet economy.  However, they unintentionally triggered an opening of debate throughout the country.  The increased freedoms allowed people to more openly criticize the government and demand changes.  \n\nAfghanistan and Chernobyl: In the late 1980s, two events symbolized the incompetence of the Soviet government.  The failure of the Afghanistan war resulted in a loss of confidence in the Soviet military. The Chernobyl disaster revealed the incompetence and duplicity of the Soviet regime, resulting in a further erosion of trust.",

Sport touring is sometimes recognized as a seventh category or integrated with the touring category.\n\nAlthough there are many names and systems for classifying types of motorcycles based on their characteristics and usage, there are generally six categories recognized by most motorcycle manufacturers and organizations.\n\nStrong distinctions are usually made between the six main types of motorcycles and other motorcycles. Scooter, moped, underbone, miniature, pocket, electric, and three-wheeled motorcycles are generally excluded from the main categories but other classification schemes may include these as types of motorcycles.\n\nThere is no universal system for classifying all types of motorcycles. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or legal definitions of a motorcycle established by certain legal jurisdictions for motorcycle registration, emissions, road traffic safety rules or motorcyclist licensing. There are also informal classifications or nicknames used by manufacturers, riders, and the motorcycling media. Some experts do not recognize sub-types, like naked bike, that \"purport to be classified\" outside the six usual classes, because they fit within one of the main types and are recognizable only by cosmetic changes.\n\nStreet motorcycles are motorcycles designed for being ridden on paved roads. They have smooth tires with tread patterns and engines generally in the 125 cc (7.6 cu in) and over range. Typically, street motorcycles are capable of speeds up to 100 mph (160 km/h), and many of speeds in excess of 125 mph (201 km/h).

Our models are implemented in DyNet BIBREF13.\nMorphological analysis is the task of creating a morphosyntactic description for a given word. It can be framed in a context-agnostic manner (as in our case) or within a given context, as for instance for the SIGMORPHON 2019 second shared task BIBREF11. We trained an encoder-decoder model that receives the form as character-level input, encodes it with a BiLSTM encoder, and then an attention enhanced decoder BIBREF14 outputs the corresponding sequence of morphological tags, implemented in DyNet. The baseline results are shown in Table . The exact-match accuracy of 67% is lower than the average accuracy that context-aware systems can achieve, and it highlights the challenge that the complexity of the tonal system of SJQ Chatino can pose.\nLemmatization is the task of retrieving the underlying lemma from which an inflected form was derived. Although in some languages the lemma is distinct from all forms, in SJQ Chatino the lemma is defined as the completive third-person singular form. As a computational task, lemmatization entails producing the lemma given an inflected form (and possibly, given a set of morphological tags describing the input form). Popular approaches tackle it as a character-level edit sequence generation task BIBREF15, or as a character-level sequence-to-sequence task BIBREF16. For our baseline lemmatization systems we follow the latter approach.

        "evidence": "The task assigned to annotators was to read sentences one at a time and label them with with binary labels indicating the polarity (i.e., positive/negative). Note that, the participants were not instructed to annotate whether a sentence is sarcastic or not., to rule out the Priming Effect (i.e., if sarcasm is expected beforehand, processing incongruity becomes relatively easier BIBREF12 ). The setup ensures its “ecological validity” in two ways: (1) Readers are not given any clue that they have to treat sarcasm with special attention. This is done by setting the task to polarity annotation (instead of sarcasm detection). (2) Sarcastic sentences are mixed with non sarcastic text, which does not give prior knowledge about whether the forthcoming text will be sarcastic or not.\nThe eye-tracking experiment is conducted by following the standard norms in eye-movement research BIBREF13 . At a time, one sentence is displayed to the reader along with the “aspect” with respect to which the annotation has to be provided. While reading, an SR-Research Eyelink-1000 eye-tracker (monocular remote mode, sampling rate 500Hz) records several eye-movement parameters like fixations (a long stay of gaze) and saccade (quick jumping of gaze between two positions of rest) and pupil size.\nThe accuracy of polarity annotation varies between 72%-91% for sarcastic texts and 75%-91% for non-sarcastic text, showing the inherent difficulty of sentiment annotation, when sarcasm is present in the text under consideration. Annotation errors may be attributed to: (a) lack of patience/attention while reading, (b) issues related to text comprehension, and (c) confusion/indecisiveness caused due to lack of context.\nFor our analysis, we do not discard the incorrect annotations present in the database. Since our system eventually aims to involve online readers for sarcasm detection, it will be hard to segregate readers who misinterpret the text. We make a rational assumption that, for a particular text, most of the readers, from a fairly large population, will be able to identify sarcasm. Under this assumption, the eye-movement parameters, averaged across all readers in our setting, may not be significantly distorted by a few readers who would have failed to identify sarcasm. This assumption is applicable for both regular and multi-instance based classifiers explained in section SECREF6 .\nAnnotation errors may be attributed to: (a) lack of patience/attention while reading, (b) issues related to text comprehension, and (c) confusion indecisiveness caused due to lack of context.",

The improvement could be justified just by the larger vocabulary in Twi, but in the case of Yorùbá the enhancement is there with almost half of the vocabulary size. We found out that adding some noisy texts (C2 dataset) slightly improves the correlation for Twi language but not for the Yorùbá language. The Twi language benefits from Wikipedia articles because its inclusion doubles the vocabulary and reduces the bias of the model towards religious texts. However, for Yorùbá, noisy texts often ignore diacritics or tonal marks which increases the vocabulary size at the cost of an increment in the ambiguity too. As a result, the correlation is slightly hurt. One would expect that training with more data would improve the quality of the embeddings, but we found out with the results obtained with the C3 dataset, that only high-quality data helps. The addition of JW300 boosts the vocabulary in both cases, but whereas for Twi the corpus mixes dialects and is noisy, for Yorùbá it is very clean and with full diacritics. Consequently, the best embeddings for Yorùbá are obtained when training with the C3 dataset, whereas for Twi, C2 is the best option.

        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nWe differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.",

In recent years, many large-scale RC datasets in English BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6 have nourished the development of numerous powerful and diverse RC models BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11. The state-of-the-art model BIBREF12 on SQuAD, one of the most widely used RC benchmarks, even surpasses human-level performance. Nonetheless, RC on languages other than English has been limited due to the absence of sufficient training data. Although some efforts have been made to create RC datasets for Chinese BIBREF13, BIBREF14 and Korean BIBREF15, it is not feasible to collect RC datasets for every language since annotation efforts to collect a new RC dataset are often far from trivial. Therefore, the setup of transfer learning, especially zero-shot learning, is of extraordinary importance.\nExisting methods BIBREF16 of cross-lingual transfer learning on RC datasets often count on machine translation (MT) to translate data from source language into target language, or vice versa. These methods may not require a well-annotated RC dataset for the target language, whereas a high-quality MT model is needed as a trade-off, which might not be available when it comes to low-resource languages.\nIn this paper, we leverage pre-trained multilingual language representation, for example, BERT learned from multilingual un-annotated sentences (multi-BERT), in cross-lingual zero-shot RC. We fine-tune multi-BERT on the training set in source language, then test the model in target language, with a number of combinations of source-target language pair to explore the cross-lingual ability of multi-BERT. Surprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese. Recent studies BIBREF17, BIBREF12, BIBREF18 show that cross-lingual language models have the ability to enable preliminary zero-shot transfer on simple natural language understanding tasks, but zero-shot transfer of RC has not been studied. To our knowledge, this is the first work systematically exploring the cross-lingual transferring ability of multi-BERT on RC tasks.\nSurprisingly, we find that the models have the ability to transfer between low lexical similarity language pair, such as English and Chinese.",

        "question": "Is the adaptation method applicable to other e2e auto encoder models, e.g., GAN or VAE. In another words, is there any specific advantage of selecting MDN?",
        "answer": "Just to clarify, the choice of a GAN, VAE, or MDN pertains only to the generative model of the channel, and not the end-to-end autoencoder. The proposed method is specific to a mixture density network channel model. Adaptation of other generative models such as GAN and VAE using a small number of samples is an interesting but challenging problem. The choice of MDN as the channel model for this problem comes with the following advantages:\nThe conditional density corresponding to the MDN is a mixture of Gaussians, whose parametric form is easy to adapt using symbol and component-conditional affine transformations. The number of affine transformation parameters is much smaller than the number of MDN parameters, making the adaptation less susceptible to overfitting on the small dataset from the target distribution.\nThe MDN choice makes it possible to derive a closed-form KL-divergence between the source and target Gaussian mixtures under some mild assumptions. This is used as a regularization term in the adaptation objective, which allows to directly constrain the change in distribution.\nThe affine transformation property between the mixture of Gaussians allows us to design an input transformation method at the decoder (Sec 4.1) that can compensate for changes in the distribution of the channel output. This same property also allows us to propose a validation metric that is used for selecting the hyper-parameter lambda (Appendix C.3).",
        "evidence": "Consider the same problem setup as § 3, where we observe a small dataset of samples from the target channel distribution. Suppose we have adapted the MDN channel by optimizing over the parameters ψ, we can use the inverse-affine feature transformations (defined in Eq. ()) to transform the channel output y from a component of the target Gaussian mixture to the same component of the source Gaussian mixture. However, this transformation requires knowledge of both the channel input x and the mixture component i, which are not observed (latent) at the decoder. We address this by first determining the most-probable pair of channel input and mixture component for a given y (using the MAP rule), and applying the corresponding inverse-affine feature transformation as\nThe joint posterior over the channel input x and mixture component i, given the channel output y is based on the adapted (target) Gaussian mixture, given by\n.\nThe adapted decoder based on the above affine feature transformation (see Fig.) is defined as  In the previous method, an input transformation layer is introduced at the decoder only during adaptation, but not during training of the autoencoder. Alternatively, we propose an input transformation layer at the decoder that takes the channel output y and produces a best estimate of the encoded symbol x, which is then given as input to the decoder as shown in Fig.. This input transformation layer is included during the autoencoder training as a fixed non-linear transformation that does not have any trainable parameters. Since the decoder is trained to predict using x instead of y, it is inherently robust to changes in the distribution of y.\nGiven a generative model of the channel conditional density using Gaussian mixtures, we can estimate the plug-in Bayes posterior distribution of x given y, P θc (x | y) (ref.\nEq. ()). From this, we can find the MAP estimate of x given y as\nThe adapted decoder based on this input transformation, referred to as the MAP symbol estimation (SE) layer, is defined as\nand illustrated in Fig.. Whenever the MDN model is adapted to changes in the channel distribution, resulting in a new MDN with parameters θ c , the MAP SE layer is also updated using θ c . This input transformation shields the decoder from changes to the distribution of the channel output y.\nSince the MAP SE layer is also included in the autoencoder during training, the non-differentiable argmax function presents an obstacle to training the autoencoder using backpropagation. We address this by using a temperature-scaled softmax approximation to the argmax, which is differentiable and provides a close approximation for small temperature values. This approximation is used only during training, whereas the exact argmax is used during inference. Details on this approximation, and a modified autoencoder training algorithm with temperature annealing are discussed in Appendix C.5.\nComments. The proposed input transformation methods at the decoder have some similarities to equalization methods used in communication receivers. However, our problem setting considers a memoryless channel, and does not deal with intersymbol interference (ISI), which is the main focus of equalization methods. A key advantage of the proposed adaptation is that it is very computationally efficient to implement at the receiver of a communication system. A discussion of the computational complexity of the proposed methods is given in Appendix C.4.\nSuppose we have adapted the MDN channel by optimizing over the parameters ψ, we can use the inverse-affine feature transformations (defined in Eq. (4)) to transform the channel output y from a component of the target Gaussian mixture to the same component of the source Gaussian mixture.",

        "question": "What method is used for evaluating the distance between individual words from a query and a document?",
        "answer": "It is a neural word embedding approach.",
        "evidence": "In information retrieval (IR), queries and documents are typically represented by term vectors where each term is a content word and weighted by tf-idf, i.e. the product of the term frequency and the inverse document frequency, or other weighting schemes BIBREF0 . The similarity of a query and a document is then determined as a dot product or cosine similarity. Although this works reasonably, the traditional IR scheme often fails to find relevant documents when synonymous or polysemous words are used in a dataset, e.g. a document including only “neoplasm\" cannot be found when the word “cancer\" is used in a query. One solution of this problem is to use query expansion BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 or dictionaries, but these alternatives still depend on the same philosophy, i.e. queries and documents should share exactly the same words.\nWhile the term vector model computes similarities in a sparse and high-dimensional space, the semantic analysis methods such as latent semantic analysis (LSA) BIBREF5 , BIBREF6 and latent Dirichlet allocation (LDA) BIBREF7 learn dense vector representations in a low-dimensional space. These methods choose a vector embedding for each term and estimate a similarity between terms by taking an inner product of their corresponding embeddings BIBREF8 . Since the similarity is calculated in a latent (semantic) space based on context, the semantic analysis approaches do not require having common words between a query and documents. However, it has been shown that LSA and LDA methods do not produce superior results in various IR tasks BIBREF9 , BIBREF10 , BIBREF11 and the classic ranking method, BM25 BIBREF12 , usually outperforms those methods in document ranking BIBREF13 , BIBREF14 .\nNeural word embedding BIBREF15 , BIBREF16 is similar to the semantic analysis methods described above. It learns low-dimensional word vectors from text, but while LSA and LDA utilize co-occurrences of words, neural word embedding learns word vectors to predict context words BIBREF10 . Moreover, training of semantic vectors is derived from neural networks. Both co-occurrence and neural word embedding approaches have been used for lexical semantic tasks such as semantic relatedness (e.g. king and queen), synonym detection (e.g. cancer and carcinoma) and concept categorization (e.g. banana and pineapple belong to fruits) BIBREF10 , BIBREF17 . But, Baroni et al. Baroni2014 showed that neural word embedding approaches generally performed better on such tasks with less effort required for parameter optimization. The neural word embedding models have also gained popularity in recent years due to their high performance in NLP tasks BIBREF18 .\nHere we present a query-document similarity measure using a neural word embedding approach. This work is particularly motivated by the Word Mover's Distance BIBREF19 . Unlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document. Our first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets BIBREF20 , BIBREF21 , and the experimental results showed that our approach was better than BM25 ranking. This was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.\nIn general, conventional ranking models (e.g. BM25) rely on a manually designed ranking function and require heuristic optimization for parameters BIBREF22 , BIBREF23 . In the age of information explosion, this one-size-fits-all solution is no longer adequate. For instance, it is well known that links to a web page are an important source of information in web document search BIBREF24 , hence using the link information as well as the relevance between a query and a document is crucial for better ranking. In this regard, learning to rank BIBREF22 has drawn much attention as a scheme to learn how to combine diverse features. Given feature vectors of documents and their relevance levels, a learning to rank approach learns an optimal way of weighting and combining multiple features.\nWe argue that the single scores (or features) produced by BM25 and our proposed semantic measure complement each other, thus merging these two has a synergistic effect. To confirm this, we measured the impact on document ranking by combining BM25 and semantic scores using the learning to rank approach, LamdaMART BIBREF25 , BIBREF26 . Trained on PubMed user queries and their click-through data, we evaluated the search performance based on the most highly ranked 20 documents. As a result, we found that using our semantic measure further improved the performance of BM25.\nTaken together, we make the following important contributions in this work. First, to the best of our knowledge, this work represents the first investigation of query-document similarity for information retrieval using the recently proposed Word Mover's Distance. Second, we modify the original Word Mover's Distance algorithm so that it is computationally less expensive and thus more practical and scalable for real-world search scenarios (e.g. biomedical literature search). Third, we measure the actual impact of neural word embeddings in PubMed by utilizing user queries and relevance information derived from click-through data. Finally, on TREC and PubMed datasets, our proposed method achieves stronger performance than BM25.\nHere we present a query-document similarity measure using a neural word embedding approach.",

        "question": "What is the limitation of existing NN-based methods？",
        "answer": "They cannot fully utilize the power of NN models for collective EL.",
        "evidence": " This work is licensed under a Creative Commons Attribution 4.0 International License. License details: http://creativecommons.org/licenses/by/4.0/\nEntity linking (EL), mapping entity mentions in texts to a given knowledge base (KB), serves as a fundamental role in many fields, such as question answering BIBREF0 , semantic search BIBREF1 , and information extraction BIBREF2 , BIBREF3 . However, this task is non-trivial because entity mentions are usually ambiguous. As shown in Figure FIGREF1 , the mention England refers to three entities in KB, and an entity linking system should be capable of identifying the correct entity as England cricket team rather than England and England national football team.\nEntity linking is typically broken down into two main phases: (i) candidate generation obtains a set of referent entities in KB for each mention, and (ii) named entity disambiguation selects the possible candidate entity by solving a ranking problem. The key challenge lies in the ranking model that computes the relevance between candidates and the corresponding mentions based on the information both in texts and KBs BIBREF4 . In terms of the features used for ranking, we classify existing EL models into two groups: local models to resolve mentions independently relying on textual context information from the surrounding words BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , and global (collective) models, which are the main focus of this paper, that encourage the target entities of all mentions in a document to be topically coherent BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 .\nGlobal models usually build an entity graph based on KBs to capture coherent entities for all identified mentions in a document, where the nodes are entities, and edges denote their relations. The graph provides highly discriminative semantic signals (e.g., entity relatedness) that are unavailable to local model BIBREF15 . For example (Figure FIGREF1 ), an EL model seemly cannot find sufficient disambiguation clues for the mention England from its surrounding words, unless it utilizes the coherence information of consistent topic “cricket\" among adjacent mentions England, Hussain, and Essex. Although the global model has achieved significant improvements, its limitation is threefold:\nTo mitigate the first limitation, recent EL studies introduce neural network (NN) models due to its amazing feature abstraction and generalization ability. In such models, words/entities are represented by low dimensional vectors in a continuous space, and features for mention as well as candidate entities are automatically learned from data BIBREF4 . However, existing NN-based methods for EL are either local models BIBREF16 , BIBREF17 or merely use word/entity embeddings for feature extraction and rely on another modules for collective disambiguation, which thus cannot fully utilize the power of NN models for collective EL BIBREF18 , BIBREF19 , BIBREF20 .\nThe second drawback of the global approach has been alleviated through approximate optimization techniques, such as PageRank/random walks BIBREF21 , graph pruning BIBREF22 , ranking SVMs BIBREF23 , or loopy belief propagation (LBP) BIBREF18 , BIBREF24 . However, these methods are not differentiable and thus difficult to be integrated into neural network models (the solution for the first limitation).\nTo overcome the third issue of inadequate training data, BIBREF17 has explored a massive amount of hyperlinks in Wikipedia, but these potential annotations for EL contain much noise, which may distract a naive disambiguation model BIBREF6 .\nIn this paper, we propose a novel Neural Collective Entity Linking model (NCEL), which performs global EL combining deep neural networks with Graph Convolutional Network (GCN) BIBREF25 , BIBREF26 that allows flexible encoding of entity graphs. It integrates both local contextual information and global interdependence of mentions in a document, and is efficiently trainable in an end-to-end fashion. Particularly, we introduce attention mechanism to robustly model local contextual information by selecting informative words and filtering out the noise. On the other hand, we apply GCNs to improve discriminative signals of candidate entities by exploiting the rich structure underlying the correct entities. To alleviate the global computations, we propose to convolute on the subgraph of adjacent mentions. Thus, the overall coherence shall be achieved in a chain-like way via a sliding window over the document. To the best of our knowledge, this is the first effort to develop a unified model for neural collective entity linking.\nIn experiments, we first verify the efficiency of NCEL via theoretically comparing its time complexity with other collective alternatives. Afterwards, we train our neural model using collected Wikipedia hyperlinks instead of dataset-specific annotations, and perform evaluations on five public available benchmarks. The results show that NCEL consistently outperforms various baselines with a favorable generalization ability. Finally, we further present the performance on a challenging dataset WW BIBREF19 as well as qualitative results, investigating the effectiveness of each key module.\nHowever, existing NN-based methods for EL are either local models (Yamada et al., 2017; Gupta et al., 2017) or merely use word/entity embeddings for feature extraction and rely on another modules for collective disambiguation, which thus cannot fully utilize the power of NN models for collective EL (Globerson et al., 2016; Guo and Barbosa, 2017; Phan et al., 2018).",

        "evidence": "We compared our full method (TextTiling with heuristic-max based on embeddings trained by virtual sentences) with several baselines:\nRandom. We randomly segmented conversation sessions. In this baseline, we were equipped with the prior probability of segmentation.\nMMD. We applied the MinMax-Dotplotting (MMD) approach proposed by Ye et al. BIBREF24 . We ran the executable program provided by the authors.\nTextTiling w/ tf INLINEFORM0 idf features. We implemented TextTiling ourselves according to BIBREF12 .\nWe tuned the hyperparameter INLINEFORM0 in Equation ()on the validation set to make the number of segmentation close to that of manual annotation, and reported precision, recall, and the F-score on the test set in Table TABREF18 . As seen, our approach significantly outperforms baselines by a large margin in terms of both precision and recall. Besides, we can see that MMD obtains low performance, which is mainly because the approach cannot be easily adapted to other datasets like short sentences of conversation utterances. In summary, we achieve an INLINEFORM1 -score higher than baseline methods by more than 20%, showing the effectiveness of enhancing TextTiling with modern word embeddings.\nWe further conducted in-depth analysis of different strategies of training word-embeddings and matching heuristics in Table TABREF21 . For word embeddings, we trained them on the 3M-sentence dataset with three strategies: (1) virtual-sentence context proposed in our paper; (2) within-sentence context, where all words (except the current one) within a sentence (either a query or reply) are regarded as the context; (3) window-based context, which is the original form of BIBREF25 : the context is the words in a window (previous 2 words and future 2 words in the sentence). We observe that our virtual-sentence strategy consistently outperforms the other two in all three matching heuristics. The results suggest that combining a query and a reply does provide more information in learning dialogue-specific word embeddings.\nRegarding matching heuristics, we find that in the second and third strategies of training word embeddings, the complicated heuristic-max method yields higher INLINEFORM0 -scores than simple sum pooling by 2–3%. However, for the virtual-sentence strategy, heuristic-max is slightly worse than the sum pooling. (The degradation is only 0.1% and not significant.) This is probably because both heuristic-max and virtual sentences emphasize the rich interaction between a query and its corresponding reply; combining them does not result in further gain.\nWe also notice that heuristic-avg is worse than other similarity measures. As this method is mathematically equivalent to the average of word-by-word similarity, it may have an undesirable blurring effect.\nTo sum up, our experiments show that both the proposed embedding learning approach and the similarity heuristic are effective for session segmentation. The embedding-enhanced TextTiling approach largely outperforms baselines.\nWe conducted an external experiment to show the effect of session segmentation in dialogue systems. We integrated the segmentation mechanism into a state-of-the-practice retrieval-based system and evaluated the results by manual annotation, similar to our previous work BIBREF27 , BIBREF31 , BIBREF32 .\nConcretely, we compared our session segmentation with fixed-length context, used in BIBREF11 . That is to say, the competing method always regards two previous utterances as context. We hired three workers to annotate the results with three integer scores (0–2 points, indicating bad, borderline, and good replies, respectively.) We sampled 30 queries from the test set of 100 sessions. For each query, we retrieved 10 candidates and computed p@1 and nDCG scores BIBREF33 (averaged over three annotators). Provided with previous utterances as context, each worker had up to 1000 sentences to read during annotation.\nTable TABREF26 presents the results of the dialogue system with session segmentation. As demonstrated, our method outperforms the simple fixed-context approach in terms of both metrics. We computed the inner-annotator agreement: std INLINEFORM0 0.309; 3-discrete-class Fleiss' kappa score INLINEFORM1 0.411, indicating moderate agreement BIBREF34 .\nCase Study. We present a case study on our website: https://sites.google.com/site/sessionsegmentation/. From the case study, we see that the proposed approach is able to segment the dialogue session appropriately, so as to better utilize background information from a conversation session.\nIn this paper, we addressed the problem of session segmentation for open-domain dialogue systems. We proposed an embedding-enhanced TextTiling approach, where we trained embeddings with the novel notion of virtual sentences; we also proposed several heuristics for similarity measure. Experimental results show that both our embedding learning and similarity measuring are effective in session segmentation, and that with our approach, we can improve the performance of a retrieval-based dialogue system.\nWe thank anonymous reviewers for useful comments and Jingbo Zhu for sharing the MMD executable program.

        "evidence": "Affordance-aware navigation is a major challenge in solving complex and long-horizon indoor tasks such as ALFRED with both navigation and object interactions. Specifically, given each object of interest in the scene, the agent is required to not only find and approach it but also end up at a pose (x, y, r, h), that is feasible for subsequent interactions with the object. For instance, to open a fridge, the robot should approach the fridge closely enough (so the door is within reach), look at it (so that the fridge is in the field of view), and leave enough room to open the door. To solve a long-horizon task involving multiple navigation and object interaction subgoals, it is natural to use an explicit semantic map, either 2D or 3D, of the environment (similar to Neural Active SLAM Chaplot et al. (2020a)), together with model-based planning (e.g. as in). This line of work tends to generalize better than models that directly learn mappings from human instructions to navigation & interaction actions (e.g., E.T.). With perfect knowledge of the environment, it is possible to achieve (nearly) perfect performance. In practice, however, the semantic map acquired at inference time is usually far from ideal, primarily due to Incompleteness (missing information due to insufficient exploration of the scene) and Inaccuracy (erroneous object location prediction on the map, especially for small objects).\nTo improve exploration performance, we propose a multimodal module that, at each step, predicts an exploration action a ∈ {MoveAhead, RotateLeft, RotateRight} by taking visual observations & actions in the past, step-by-step language instructions, and the explored area map which indicates where the agent has visited. We show that, compared to existing model-based approaches on ALFRED (e.g., which applies random exploration), our use of lowlevel language instructions leads to more efficient exploration. The proposed exploration module operates at the subgoal level and only predicts exploration actions (in contrast to E.T. which directly predicts actions for the entire task). The extra modality (the explored area) facilitates exploration by providing the agent with explicit spatial information. We illustrate the exploration module in Figure, elaborate its details in Section 4.3, and empirically demonstrate its advantages in Section 5.\nThe proposed exploration module operates at the subgoal level and only predicts exploration actions (in contrast to E.T. which directly predicts actions for the entire task).****The multimodal exploration module consists of several sub-modules, either learned or pretrained/fixed. At a high level, given a task, the exploration go through its navigation subgoals one by one, with the subgoal parser (see Section 4.4) predicting whether a subgoal is for navigation.",

With these pairs of triplets, we can train the system to predict a user's choice on a new image and a new question, given the same user's choice on the previous image and its associated question. User's choice $x_{ans_i}$ is represented as one-hot vector where the size of the vector is equal to the number of possible choices.

In other words, a question whose answer is so obvious that it can be answered in an identical way would not be valid as an interactive question. In order to make sure that each generated question allows for multiple possible answers, we internally utilize the VQA module.

Among generally recognized species, it is the second-largest species of ray, only surpassed by the giant oceanic manta ray.\n\nThe species was described in 1868 by Gerard Krefft, the director of the Australian Museum. He named it M. alfredi in honor of Alfred, Duke of Edinburgh, the first member of the British royal family to visit Australia. It was originally described as part of the genus Manta but in 2017 was changed, along with the rest of the mantas, to be included as part of the genus Mobula.\n\nReef manta rays are typically 3 to 3.5 m (9.8 to 11.5 ft) in disc width, with a maximum size of about 5.5 m (18 ft). For a long time included in M. birostris, the status of the reef manta ray as a separate species was only confirmed in 2009.

        "question": "Given the below reference text about Luftwaffe, tell me for how many years was this military organisation active officially in Germany?",
        "evidence": "The Luftwaffe was the aerial-warfare branch of the German Wehrmacht before and during World War II. Germany's military air arms during World War I, the Luftstreitkräfte of the Imperial Army and the Marine-Fliegerabteilung of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force.\n\nDuring the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the Luftwaffe's existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a Luftwaffe detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing ground for new tactics and aircraft. Partially as a result of this combat experience, the Luftwaffe had become one of the most sophisticated, technologically advanced, and battle-experienced air forces in the world when World War II broke out in September 1939. By the summer of 1939, the Luftwaffe had twenty-eight Geschwader (wings). The Luftwaffe also operated a paratrooper force known as the Fallschirmjäger.\n\nThe Luftwaffe proved instrumental in the German victories across Poland and Western Europe in 1939 and 1940. During the Battle of Britain, however, despite inflicting severe damage to the RAF's infrastructure and, during the subsequent Blitz, devastating many British cities, the German air force failed to batter the beleaguered British into submission. From 1942, Allied bombing campaigns gradually destroyed the Luftwaffe's fighter arm. From late 1942, the Luftwaffe used its surplus ground support and other personnel to raise Luftwaffe Field Divisions. In addition to its service in the West, the Luftwaffe operated over the Soviet Union, North Africa and Southern Europe. Despite its belated use of advanced turbojet and rocket-propelled aircraft for the destruction of Allied bombers, the Luftwaffe was overwhelmed by the Allies' superior numbers and improved tactics, and a lack of trained pilots and aviation fuel. In January 1945, during the closing stages of the Battle of the Bulge, the Luftwaffe made a last-ditch effort to win air superiority, and met with failure. With rapidly dwindling supplies of petroleum, oil, and lubricants after this campaign, and as part of the entire combined Wehrmacht military forces as a whole, the Luftwaffe ceased to be an effective fighting force.\n\nAfter the defeat of Nazi Germany, the Luftwaffe was disbanded in 1946. During World War II, German pilots claimed roughly 70,000 aerial victories, while over 75,000 Luftwaffe aircraft were destroyed or significantly damaged. Of these, nearly 40,000 were lost entirely. The Luftwaffe had only two commanders-in-chief throughout its history: Hermann Göring and later Generalfeldmarschall Robert Ritter von Greim for the last two weeks of the war.",

        "answer": "How can I fully participate in a capitalistic society without examining it in the first place? That is \nthe necessary first step to then “re-examine” capitalism, which I unequivocally support. Blindly \nfollowing a belief, even an economic one, without critically assessing it can run the danger of \nmaking me complicit in contributing to the consequences of that belief even without any intent.\nI can only fully speak from my experience, so that is the lens through which I approach this \nclass; on the larger scale, however, a re-examination is also called for to discern whether \ncapitalism is the best course of action in the long term. \nUpon this re-examination, I conclude that capitalism is not broken: it is functioning as intended, \nto create economic value for the majority groups who popularized it.\n\nCapitalism in the United States has achieved such fast-paced progress because Black slaves, minority immigrants, and unpaid domestic laborers have assumed the lion’s share of building the \nsystem, and the legacies of these systems result in the inequities of race, class, and gender as \ndiscussed in class. Such inequities are not only shameful, but plainly unnecessary to continue making such strides in industry, health, longevity, and sharing of ideas. Therefore, capitalism should be amended so that workers more equitably reap the fruits of their labor. Exorbitant CEO pay and the \ndistribution of the majority of profits towards shareholders; global factories which exploit \nchildren while imposing unclean and unsafe working conditions on many; unfettered \nproduction decimating the planet – should all be amended. Capitalism has grown automation, \ntechnology, and AI as well as the development and sharing of thought to remarkable levels. Such progress can be leveraged to address these issues and more. This isn’t idealistic or wishful thinking; though economic situations can seem like “given”\ncircumstances, they are not to be taken for granted; capitalism is a human institution which \nrequires human participation to uphold them. Therefore, capitalism also can be amended. \nIntroducing another consideration is not a limitation on profits; rather, considering additional \nparameters inspires innovation, as embraced by many leading organizations. \nBut at what pace shall capitalism be amended? The modern United States has necessary checks \nand balances in the legal systems to uphold the laws and enforce the regulations, which makes \nme believe that change should be incremental as to learn from our past and carefully curate a \nnew future. It takes time to engage the partners vital to change – academics, politicians, social \nleaders, business leaders – and transformative change may leave some key stakeholders \nbehind.

Shi et al., arXiv 2021.",
        "evidence": "We begin with bridging logical expressions and graph patterns based on two intuitions/assumptions:\n• A relation can often be inferred from other relations with a combination of simple logical rules that do not involve too many nodes. • One can predict relation existence by finding whether the subgraphs containing the pair are similar to the subgraphs containing an edge with the same relation.\nTake Figure as an example where we wish to predict whether Person E lives in London.\nAn example of the first intuition goes as follows: if Person E watches the soccer matches with club Arsenal, which is based in London, then Person E may also live in London. However, such logical rules (so called chain-like logic rules in) may not always hold, requiring probabilistic inference. For instance, Person G watches the matches with FC Barcelona, which is Based in Barcelona, but he does not live in the same city. To make more accurate predictions, we need to combine other possible logical rules, such as \"Friends often live in the same city\" -in this case, Person E and Person H are friends, and Person H lives in London (some of them construct certain patterns are called tree-like logic rules or graph-like rules).\nThe second intuition tells us that we can predict whether Person E lives in London by checking if the subgraphs containing the pair (Person E, London) (named target subgraphs, e.g. Person E -Arsenal -London) are similar to the subgraphs containing a live relation (named supporting subgraphs, e.g. Person I -Chelsea -London). Similarity computation is done by a neural network. To determine whether the two sets of subgraphs are similar, we additionally compare the target subgraphs against another set of subgraphs that do not contain the relation (named refuting subgraphs, e.g. Person E -Person G -Barcelona) as a baseline. A variety of options exist for selecting the refuting subgraphs, ranging from selecting those having the same topology regardless of the actual relation types, to those having both the same shape and relation types.\nIn addition, we do not include the edge of live in the supporting subgraphs to avoid information leakage. We also require the supporting subgraphs and refuting subgraphs to have the same shape as that of the target subgraphs in order to make similarity computation focus more on the node features and relation types rather than the topology, and that is why we call both supporting subgraphs and refuting subgraphs analogy subgraphs. This enables us to predict live relation with the pipeline above without learning an explicit embedding for live relation, unlike prior works. The reason is that the information of live relation can be implicitly expressed by the other relations found in the supporting and refuting subgraphs, e.g. live can be expressed by watch and based. This serves as the basis for our model's generalizability to relations that have no occurrence in the training set.\nWe can describe what kind of subgraphs we are looking for in the above example with logical expressions. The target subgraphs above will have the logical expression Source(x) ∧ Target(y) ∧ Edge(x, z) ∧ Edge(z, y), where Source(x) means if node x is the source node s, Target(y) means if node y is the target node t, and Edge(x, z) means if there exists an edge regardless of relation type between x and z. Our task is to determine whether an edge of relation type r exists between s and t. The supporting subgraphs will have Edge(x, z) ∧ Edge(z, y) ∧ Edge r (x, y), meaning that the subgraph can be any 3-cycle except that there must be an edge with relation type r. The refuting subgraphs will have Edge(x, z) ∧ Edge(z, y) ∧ ¬Edge r (x, y), meaning that it can be any 2-path except that the starting node and ending node must not have an edge with relation r in between. This leads to the concept of graph patterns, defined as follows:\nDefinition 1 (Graph Pattern). A graph pattern is a logical function that takes in a subgraph as input and returns a boolean value, consisting of logical operators (¬, ∧, ∨) as well as indicator operators determined by the existence of nodes and edges, the latter includes:\n• Source(x) and Target(x), returning true iff x is the source node and target node, respectively.\n• Edge(x, y), returning true iff there exists an edge between node x and y.\n• Edge r (x, y), returning true iff there exists an edge of relation r between node x and y.\nWe call a subgraph S matches a graph pattern Π if true is returned when S is applied to Π. Such operation is already well supported in graph databases, and in the following sections we give more efficient algorithms that perform matching with simple patterns.\nTake Figure 1 as an example where we wish to predict whether Person E lives in London. An example of the first intuition goes as follows:  if Person E watches the soccer matches with club Arsenal, which is based in London, then Person E may also live in London. However, such logical rules (so called chain-like logic rules in (Yang et al., 2017)) may not always hold, requiring probabilistic inference.

        "evidence": "Recently, there is a surge of excitement in adding numerous new domains to conversational agents such as Alexa, Google Assistant, Cortana and Siri to support a myriad of use cases. However, building a slot tagger, which is a key component for natural language understanding (NLU) BIBREF0 , for a new domain requires massive amounts of labeled data, hindering rapid development of new skills. To address the data-intensiveness problem, domain adaptation approaches have been successfully applied. Previous approaches are roughly categorized into two groups: data-driven approaches BIBREF1 , BIBREF2 and model-driven approaches BIBREF3 , BIBREF4 .\nIn the data-driven approach, new target models are trained by combining target domain data with relevant data from a repository of arbitrary labeled datasets using domain adaptation approaches such as feature augmentation BIBREF1 . A disadvantage of this approach is the increase in training time as the amount of reusable data grows. The reusable data might contain hundreds of thousands of samples, making iterative refinement prohibitive. In contrast, the model-driven approach utilizes “expert\" models for summarizing the data for reusable slots BIBREF3 , BIBREF4 . The outputs of the expert models are directly used when training new domains, allowing for faster training. A drawback of this approach is that it requires explicit concept alignments which itself is not a trivial task, potentially missing lots of reusable concepts. Additionally, it's not easy to generalize these models to new, unseen slots.\nIn this paper, we present a new domain adaptation technique for slot tagging inspired by recent advances in zero-shot learning. Traditionally, slot tagging is formulated as a sequence labeling task using the BIO representation (Figure 1 ). Our approach formulates this problem as detecting spans that contain values for each slot as shown in Figure 1 . For implicit transfer of reusable concepts across domains, we represent slots in a shared latent semantic space by embedding the slot description. With the shared latent space, domain adaptation can simply be done by fine-tuning a base model, which is trained on massive data, with a handful of target domain data without any explicit concept alignments. A similar idea of utilizing zero-shot learning for slot tagging has been proven to work in semi-supervised settings BIBREF5 . Our zero-shot model architecture differs from this by adding: 1) an attention layer to produce the slot-aware representations of input words, 2) a CRF layer to better satisfy global consistency constraints, 3) character-level embeddings to incorporate morphological information. Despite its simplicity, we show that our model outperforms all existing methods including the previous zero-shot learning approach in domain adaptation settings.\nWe first describe our approach called Zero-Shot Adaptive Transfer model (ZAT) in detail. We then describe the dataset we used for our experiments. Using this data, we conduct experiments comparing our ZAT model with a set of state-of-the-art models: Bag-of-Expert (BoE) models and their non-expert counterparts BIBREF4 , and the Concept Tagger model BIBREF5 , showing that our model can lead to significant F1-score improvements. This is followed by an in-depth analysis of the results. We then provide a survey of related work and concluding remarks.\nIn this paper, we present a new domain adaptation technique for slot tagging inspired by recent advances in zeroshot learning.",

        "answer": "A neural network trained with large amounts of purchase and click signals.",
        "evidence": "At a high level, as shown in Figure FIGREF4 , a product search engine works as follows: a customer issues a query, which is passed to a lexical matching engine (typically an inverted index BIBREF0 , BIBREF1 ) to retrieve all products that contain words in the query, producing a match set. The match set passes through stages of ranking, wherein top results from the previous stage are re-ranked before the most relevant items are finally displayed. It is imperative that the match set contain a relevant and diverse set of products that match the customer intent in order for the subsequent rankers to succeed. However, inverted index-based lexical matching falls short in several key aspects:\nIn this paper, we address the question: Given rich customer behavior data, can we train a deep learning model to retrieve matching products in response to a query? Intuitively, there is reason to believe that customer behavior logs contain semantic information; customers who are intent on purchasing a product circumvent the limitations of lexical matching by query reformulation or by deeper exploration of the search results. The challenge is the sheer magnitude of the data as well as the presence of noise, a challenge that modern deep learning techniques address very effectively.\nProduct search is different from web search as the queries tend to be shorter and the positive signals (purchases) are sparser than clicks. Models based on conversion rates or click-through-rates may incorrectly favor accessories (like a phone cover) over the main product (like a cell phone). This is further complicated by shoppers maintaining multiple intents during a single search session: a customer may be looking for a specific television model while also looking for accessories for this item at the lowest price and browsing additional products to qualify for free shipping. A product search engine should reduce the effort needed from a customer with a specific mission (narrow queries) while allowing shoppers to explore when they are looking for inspiration (broad queries).\nAs mentioned, product search typically operates in two stages: matching and ranking. Products that contain words in the query ( INLINEFORM0 ) are the primary candidates. Products that have prior behavioral associations (products bought or clicked after issuing a query INLINEFORM1 ) are also included in the candidate set. The ranking step takes these candidates and orders them using a machine-learned rank function to optimize for customer satisfaction and business metrics.\nWe present a neural network trained with large amounts of purchase and click signals to complement a lexical search engine in ad hoc product retrieval. Our first contribution is a loss function with a built-in threshold to differentiate between random negative, impressed but not purchased, and purchased items. Our second contribution is the empirical result that recommends average pooling in combination with INLINEFORM0 -grams that capture short-range linguistic patterns instead of more complex architectures. Third, we show the effectiveness of consistent token hashing in Siamese networks for zero-shot learning and handling out of vocabulary tokens.\nIn Section SECREF2 , we highlight related work. In Section SECREF3 , we describe our model architecture, loss functions, and tokenization techniques including our approach for unseen words. We then introduce the readers to the data and our input representations for queries and products in Section SECREF4 . Section SECREF5 presents the evaluation metrics and our results. We provide implementation details and optimizations to efficiently train the model with large amounts of data in Section SECREF6 . Finally, we conclude in Section SECREF7 with a discussion of future work.\nWe present a neural network trained with large amounts of purchase and click signals to complement a lexical search engine in ad hoc product retrieval.",

The last row shows the performance of the complete CEQE with all the components. As the baseline features released in the WMT2018 QE Shared Task for English-Latvian are incomplete, we train our CEQE model without using such features. We can glean several observations from this data:\nBecause the number of “OK” tags is much larger than the number of “BAD” tags, the model is easily biased towards predicting the “OK” tag for each target word. The F1-OK scores are higher than the F1-BAD scores across all the language pairs.\nFor German-English, English Czech, and English-German (SMT), adding the baseline features can significantly improve the F1-BAD scores.\nFor English-Czech, English-German (SMT), and English-German (NMT), removing POS tags makes the model more biased towards predicting “OK” tags, which leads to higher F1-OK scores and lower F1-BAD scores.\nAdding the convolution layer helps to boost the performance of F1-Multi, especially on English-Czech and English-Germen (SMT) tasks. Comparing the F1-OK scores of the model with and without the convolution layer, we find that adding the convolution layer help to boost the F1-OK scores when translating from English to other languages, i.e., English-Czech, English-German (SMT and NMT).

Based on releasing of large text corpus on social media and the emotion categories proposed by BIBREF1, BIBREF2, numerous models have provided and achieved fabulous precision so far. For example, DeepMoji BIBREF3 which utilized transfer learning concept to enhance emotions and sarcasm understanding behind the target sentence. CARER BIBREF4 learned contextualized affect representations to make itself more sensitive to rare words and the scenario behind the texts.\nAs methods become mature, text-based emotion detecting applications can be extended from a single utterance to a dialogue contributed by a series of utterances.

The same utterances in Table TABREF2, even the same person said the same sentence, the emotion it convey may be various, which may depend on different background of the conversation, tone of speaking or personality.

For example, Hasan and Ng as well as Thomas et al. require that posts written by the same author have the same stance BIBREF9 , BIBREF10 . The addition of this constraint yields accuracy improvements of 1–7% for some models and datasets. Hasan and Ng later added user-interaction constraints and ideology constraints BIBREF7 : the former models the relationship among posts in a sequence of replies and the latter models inter-topic relationships, e.g., users who oppose abortion could be conservative and thus are likely to oppose gay rights.\nFor work focusing on online forum text, since posts are linked through user replies, sequential labeling methods have been used to model relationships between posts. For example, Hasan and Ng use hidden Markov models (HMMs) to model dependent relationships to the preceding post BIBREF9 ; Burfoot et al. use iterative classification to repeatedly generate new estimates based on the current state of knowledge BIBREF11 ; Sridhar et al. use probabilistic soft logic (PSL) to model reply links via collaborative filtering BIBREF12 . In the Facebook dataset we study, we use comments instead of reply links.

But here on Earth, we are facing the challenge to make nuclear fuel hot and confined enough to start a self-sustaining ignition.\n\nImagine trying to contain the plasma (a gaseous mixture of deuterium, tritium atoms and ions, and helium the fusion product) at 100 million degrees celsius. No material can withstand that temperature. So, scientists attempt to keep the plasma (being electrically charged and having a magnetic field of its own) suspended in a magnetic field produced by superconducting magnets around the fusion chamber/vessel. This is similar to how bullet trains float on their tracks at ridiculous speeds. This process is very difficult to achieve (as compared to nuclear FISSION).\n\n2. It produces radioactive waste.\nThough nuclear power plants only emit negligible amounts of carbon dioxide into the atmosphere, its nuclear fuel chain process does produce radioactive waste.\n\nThe radioactive waste produced with fusion is not the same as with fission, and the two are often confused. With a nuclear fission reactor, the radiation is alpha particles, beta particles, and gamma rays (which can penetrate your skin and break apart the bonds in your DNA structure, giving you all kinds of cancer). In contrast, in a nuclear fusion reactor, the vessel wall is the only part that will be bombarded by the high energy neutrons, and if, in the worst case, all the protective layers surrounding the main fusion vessel fail, the neutron radiation will stop as soon as fusion reaction stops. In a fission reactor, the cancer-causing radiation still exists even in the waste materials, which means that extreme measures are needed to burry the waste to keep it as far away as possible from humans. In the case of nuclear fusion, the activated materials (i.e., the metal vessels which have been bombarded by neutrons) can be stored safely for about 100 years, after which the radiation level becomes so low that they can be reused in the fusion reactor again.",

        "evidence": "Neural machine translation (NMT) is popularly implemented as an encoder-decoder framework BIBREF0, in which the encoder is right in charge of source sentence representation. Typically, the input sentence is implicitly represented as a contextualized source representation through deep learning networks. By further feeding the decoder, the source representation is used to learn dependent time-step context vectors for predicting target translation BIBREF1.\nIn state-of-the-art Transformer-based encoder, self-attention mechanisms are good at capturing the general information in a sentence BIBREF2, BIBREF3, BIBREF4. However, it is difficult to distinguish which kind of information lying deeply under the language is really salient for learning source representation. Intuitively, when a person reads a source sentence, he/she often selectively focuses on the basic sentence meaning, and re-reads the entire sentence to understand its meaning completely. Take the English sentence in Table TABREF2 as an example. We manually annotate its basic meaning as a shorter sequence of words than in the original sentence, called backbone information. Obviously, these words with the basic meaning contain more important information for human understanding than the remaining words in the sentence. We argue that such backbone information is also helpful for learning source representation, and is not explicitly considered by the existing NMT system to enrich the source sentence representation.\nIn this paper, we propose a novel explicit sentence compression approach to enhance the source representation for NMT. To this end, we first design three sentence compression models to accommodate the needs of various languages and scenarios, including supervised, unsupervised, and semi-supervised ways, to learn a backbone information words sequence (as shown in Table TABREF2) from the source sentence. We then propose three translation models, including backbone source-side fusion based NMT (BSFNMT), backbone target-side fusion (BTFNMT), and both-side fusion based NMT (BBFNMT), to introduce this backbone knowledge into the existing Transformer NMT system for improving translation predictions. Empirical results on the WMT14 English-to-German and English-to-French translation tasks show that the proposed approach significantly improves the translation performance over the strong even state-of-the-art NMT baselines.\nWe then propose three translation models, including backbone source-side fusion based NMT (BSFNMT), backbone target-side fusion (BTFNMT), and both-side fusion based NMT (BBFNMT), to introduce this backbone knowledge into the existing Transformer NMT system for improving translation predictions.",

BJJ is accessible to almost anyone regardless of age, sex, or fitness level as the practitioner can determine how relaxed or aggressive to be during practicing the art.  BJJ is an excellent form of exercise and promotes cardiovascular fitness, flexibility, strength, endurance, and an overall sense of well-being.  Further, there are approaches to BJJ that resonate with people who are casual hobbyists as well as those that seek international competition- and all levels of studends across that spectru.

When the pacemaker wire or \"lead\" does not detect heart electrical activity in the chamber – atrium or ventricle – within a normal beat-to-beat time period – most commonly one second – it will stimulate either the atrium or the ventricle with a short low voltage pulse. If it does sense electrical activity, it will hold off stimulating. This sensing and stimulating activity continues on a beat by beat basis and is called \"demand pacing\". In the case of a dual-chamber device, when the upper chambers have a spontaneous or stimulated activation, the device starts a countdown to ensure that in an acceptable – and programmable – interval, there is an activation of the ventricle, otherwise again an impulse will be delivered.",

England was conquered by the Normans in 1066, after which Wales also gradually came under the control of Anglo-Normans. The process was completed in the 13th century when the Principality of Wales became a client state of the English kingdom. Meanwhile, Magna Carta began the process of reducing the English monarch's political powers. In the 16th century, English and Scottish monarchs played a central role in what became the religious English Reformation and Scottish Reformation. From 1603, the English and Scottish kingdoms were ruled by a single sovereign. From 1649 to 1660, the tradition of monarchy was broken by the republican Commonwealth of England, which followed the Wars of the Three Kingdoms. Following the installation of William III and Mary II as co-monarchs in the Glorious Revolution, the Bill of Rights 1689, and its Scottish counterpart the Claim of Right Act 1689, further curtailed the power of the monarchy and excluded Roman Catholics from succession to the throne. In 1707, the kingdoms of England and Scotland were merged to create the Kingdom of Great Britain, and in 1801, the Kingdom of Ireland joined to create the United Kingdom of Great Britain and Ireland.

        "evidence": "Evaluation of NLG models has been a long-standing open problem. While human evaluation may be ideal, it is generally expensive to conduct and does not scale well. Various automated evaluation approaches are proposed to facilitate the development and evaluation of NLG models. We summarize these evaluation approaches below.\nText Overlap Metrics, including BLEU BIBREF5, METEOR BIBREF6 and ROUGE BIBREF7, are the most popular metrics employed in the evaluation of NLG models. They evaluate generated text by comparing the similarity between the generated text and human written references. While this works well in tasks where the diversity of acceptable output is limited, such as machine translation and text summarization, text overlap metrics are shown to have weak or no correlation with human judgments in open domain natural language generation tasks BIBREF8. There are two major drawbacks in these metrics. First, text overlap metrics can not distinguish minor variations in a generated text which may make the sentence not equally grammatically correct or semantically meaningful. Second, there may exist multiple equally good outputs for the given input and comparing against one gold reference can be erroneous.\nPerplexity is commonly used to evaluate the quality of a language model. It measures how well a probability distribution predicts a sample and captures the degree of uncertainty in the model. It is used to evaluate models in open-domain NLG tasks such as story generation BIBREF2 and open domain dialogue systems. However, “how likely a sentence is generated by a given model” may not be comparable across different models and does not indicate the quality of the sentence.\nParameterized Metrics learn a parameterized model to evaluate generated text. Adversarial evaluation models BIBREF11, BIBREF12 assigns a score based on how easy it is to distinguish the dialogue model responses from human responses. However, training such a discriminator can be difficult as the binary classification task can be easily over-fitted and leads to poor generalizability BIBREF11. Moreover, the information we get from the discriminator accuracy is limited as we can not compare the quality of two generated sentences when they both succeed or fail in fooling the discriminator. Recent study shows that the discriminator accuracy does not correlate well with human preference BIBREF13. Automated Dialogue Evaluation Model (ADEM) BIBREF14 is another parameterized metric proposed for dialogue system evaluation. It learns to score a generated dialogue response based on the context and the human written reference. However, it requires human-annotated scores for generated sentences. It is generally hard to design appropriate questions for crowdsourcing these scores, which makes the annotation very expensive to get and the inter-annotator agreement score is only moderate BIBREF14. As a result, the training data is limited and noisy, which makes the scoring task even harder. It can be problematic when comparing models with similar quality. In addition, this model is designed only for evaluating dialogue response generation models. More recently, embedding similarity based metrics such as HUSE BIBREF15 and BERTScore BIBREF16. These metrics alleviate the first problem of text overlap metrics by modeling semantic similarity better. However, they can not address the response diversity problem and thus are only suitable for machine translation and text summarization.\nVarious automated evaluation approaches are proposed to facilitate the development and evaluation of NLG models.

We have quantified in particular the notions of combinatoriality and compositionality as observed in real languages as well as in a large-scale dataset produced in the framework of a web-based word association experiment BIBREF1 . We have paralleled this empirical analysis with a modeling scheme, the Blending Game, whose aim is that of identifying the main determinants for the emergence of duality of patterning in language. We analyzed the main properties of the lexicon emerged from the Blending Game as a function of the two parameters of the model, the graph connectivity $p_{link}$ and the memory scale $\\tau $ . We found that properties of the emerging lexicon related to the combinatoriality, namely the words length distribution, the frequency of use of the different forms and a measure for the combinatoriality itself, reflect both qualitatively and quantitatively the corresponding properties as measured in human languages, provided that the memory parameter $\\tau $ is sufficiently high, that is that a sufficiently high effort is required in order to understand and learn brand new forms. Conversely, the compositional properties of the lexicon are related to the parameter $p_{link}$ , that is a measure of the level of structure of the conceptual graph. For intermediate and low values of $p_{link}$ , semantic relations between objects are more differentiated with respect to the situation of a more dense graph, in which every object is related to anyone else, and compositionality is enhanced.

        "answer": "Small segments, like tweets, sometimes do not have enough information to make their semantic context clear. In contrast, larger segments, like novels, have too much variation, making it difficult to train focused models.",
        "evidence": "The variables (both predictors and outcomes) are rarely simply binary or categorical. For example, a study on language use and age could focus on chronological age (instead of, e.g., social age BIBREF19 ). However, even then, age can be modeled in different ways. Discretization can make the modeling easier and various NLP studies have modeled age as a categorical variable BIBREF20 . But any discretization raises questions: How many categories? Where to place the boundaries? Fine distinctions might not always be meaningful for the analysis we are interested in, but categories that are too broad can threaten validity. Other interesting variables include time, space, and even the social network position of the author. It is often preferable to keep the variable in its most precise form. For example, BIBREF21 perform exploration in the context of hypothesis testing by using latitude and longitude coordinates — the original metadata attached to geotagged social media such as tweets — rather than aggregating into administrative units such as counties or cities. This is necessary when such administrative units are unlikely to be related to the target concept, as is the case in their analysis of dialect differences. Focusing on precise geographical coordinates also makes it possible to recognize fine-grained effects, such as language variation across the geography of a city.\nUsing a particular classification scheme means deciding which variations are visible, and which ones are hidden BIBREF22 . We are looking for a categorization scheme for which it is feasible to collect a large enough labeled document collection (e.g., to train supervised models), but which is also fine-grained enough for our purposes. Classification schemes rarely exhibit the ideal properties, i.e., that they are consistent, their categories are mutually exclusive, and that the system is complete BIBREF22 . Borderline cases are challenging, especially with social and cultural concepts, where the boundaries are often not clear-cut. The choice of scheme can also have ethical implications BIBREF22 . For example, gender is usually represented as a binary variable in NLP and computational models tend to learn gender-stereotypical patterns. The operationalization of gender in NLP has been challenged only recently BIBREF23 , BIBREF24 , BIBREF25 .\nSupervised and unsupervised learning are the most common approaches to learning from data. With supervised learning, a model learns from labeled data (e.g., social media messages labeled by sentiment) to infer (or predict) these labels from unlabeled texts. In contrast, unsupervised learning uses unlabeled data. Supervised approaches are especially suitable when we have a clear definition of the concept of interest and when labels are available (either annotated or native to the data). Unsupervised approaches, such as topic models, are especially useful for exploration. In this setting, conceptualization and operationalization may occur simultaneously, with theory emerging from the data BIBREF26 . Unsupervised approaches are also used when there is a clear way of measuring a concept, often based on strong assumptions. For example, BIBREF3 measure “surprise” in an analysis of Darwin's reading decisions based on the divergence between two probability distributions.\nFrom an analysis perspective, the unit of text that we are labeling (or annotating, or coding), either automatic or manual, can sometimes be different than one's final unit of analysis. For example, if in a study on media frames in news stories, the theoretical framework and research question point toward frames at the story level (e.g., what is the overall causal analysis of the news article?), the story must be the unit of analysis. Yet it is often difficult to validly and reliably code a single frame at the story level. Multiple perspectives are likely to sit side-by-side in a story. Thus, an article on income inequality might point to multiple causes, such as globalization, education, and tax policies. Coding at the sentence level would detect each of these causal explanations individually, but this information would need to be somehow aggregated to determine the overall story-level frame. Sometimes scholars solve this problem by only examining headlines and lead paragraphs, arguing that based on journalistic convention, the most important information can be found at the beginning of a story. However, this leads to a return to a shorter, less nuanced analysis.\nFrom a computational perspective, the unit of text can also make a huge difference, especially when we are using bag-of-words models, where word order within a unit does not matter. Small segments, like tweets, sometimes do not have enough information to make their semantic context clear. In contrast, larger segments, like novels, have too much variation, making it difficult to train focused models. Finding a good segmentation sometimes means combining short documents and subdividing long documents. The word “document\" can therefore be misleading. But it is so ingrained in the common NLP lexicon that we use it anyway in this article.\nFor insight-driven text analysis, it is often critical that high-level patterns can be communicated. Furthermore, interpretable models make it easier to find spurious features, to do error analysis, and to support interpretation of results. Some approaches are effective for prediction, but harder to interpret. The value we place on interpretability can therefore influence the approach we choose. There is an increasing interest in developing interpretable or transparent models in the NLP and machine learning communities.\nSmall segments, like tweets, sometimes do not have enough information to make their semantic context clear. In contrast, larger segments, like novels, have too much variation, making it difficult to train focused models.",

        "evidence": "Disclaimer: Due to the nature of the paper, some examples contain highly offensive language and hate speech. They don't reflect the views of the authors in any way, and the point of the paper is to help fight such speech. Much recent interest has focused on the detection of offensive language and hate speech in online social media. Such language is often associated with undesirable online behaviors such as trolling, cyberbullying, online extremism, political polarization, and propaganda. Thus, offensive language detection is instrumental for a variety of application such as: quantifying polarization BIBREF0, BIBREF1, trolls and propaganda account detection BIBREF2, detecting the likelihood of hate crimes BIBREF3; and predicting conflict BIBREF4. In this paper, we describe our methodology for building a large dataset of Arabic offensive tweets. Given that roughly 1-2% of all Arabic tweets are offensive BIBREF5, targeted annotation is essential for efficiently building a large dataset. Since our methodology does not use a seed list of offensive words, it is not biased by topic, target, or dialect. Using our methodology, we tagged 10,000 Arabic tweet dataset for offensiveness, where offensive tweets account for roughly 19% of the tweets. Further, we labeled tweets as vulgar or hate speech. To date, this is the largest available dataset, which we plan to make publicly available along with annotation guidelines. We use this dataset to characterize Arabic offensive language to ascertain the topics, dialects, and users' gender that are most associated with the use of offensive language. Though we suspect that there are common features that span different languages and cultures, some characteristics of Arabic offensive language is language and culture specific. Thus, we conduct a thorough analysis of how Arabic users use offensive language. Next, we use the dataset to train strong Arabic offensive language classifiers using state-of-the-art representations and classification techniques. Specifically, we experiment with static and contextualized embeddings for representation along with a variety of classifiers such as a deep neural network classifier and Support Vector Machine (SVM).\nThe contributions of this paper are as follows:\nWe built the largest Arabic offensive language dataset to date that includes special tags for vulgar language and hate speech.

Work in this space has mainly focused on learning actions from articulated human pose BIBREF7 , BIBREF8 , BIBREF9 or mining spatial and temporal information from videos BIBREF10 , BIBREF11 . A number of resources have been produced, including Action Bank BIBREF12 , NTU RGB+D BIBREF13 , SBU Kinect Interaction BIBREF14 , and PKU-MMD BIBREF15 .\nMost research on video action detection has gathered video information for a set of pre-defined actions BIBREF2 , BIBREF16 , BIBREF1 , an approach known as explicit data gathering BIBREF0 . For instance, given an action such as “open door,” a system would identify videos that include a visual depiction of this action. While this approach is able to detect a specific set of actions, whose choice may be guided by downstream applications, it achieves high precision at the cost of low recall. In many cases, the set of predefined actions is small (e.g., 203 activity classes in BIBREF2 ), and for some actions, the number of visual depictions is very small.\nAn alternative approach is to start with a set of videos, and identify all the actions present in these videos BIBREF17 , BIBREF18 . This approach has been referred to as implicit data gathering, and it typically leads to the identification of a larger number of actions, possibly with a small number of examples per action.\nIn this paper, we use an implicit data gathering approach to label human activities in videos. To the best of our knowledge, we are the first to explore video action recognition using both transcribed audio and video information. We focus on the popular genre of lifestyle vlogs, which consist of videos of people demonstrating routine actions while verbally describing them. We use these videos to develop methods to identify if actions are visually present.\nThe paper makes three main contributions. First, we introduce a novel dataset consisting of 1,268 short video clips paired with sets of actions mentioned in the video transcripts, as well as manual annotations of whether the actions are visible or not. The dataset includes a total of 14,769 actions, 4,340 of which are visible. Second, we propose a set of strong baselines to determine whether an action is visible or not. Third, we introduce a multimodal neural architecture that combines information drawn from visual and linguistic clues, and show that it improves over models that rely on one modality at a time.\nBy making progress towards automatic action recognition, in addition to contributing to video understanding, this work has a number of important and exciting applications, including sports analytics BIBREF19 , human-computer interaction BIBREF20 , and automatic analysis of surveillance video footage BIBREF21 .\nThe paper is organized as follows.

        "evidence": "The Battle of Thermopylae (/θərˈmɒpɪliː/ thər-MOP-i-lee; Greek: Μάχη τῶν Θερμοπυλῶν, Máchē tōn Thermopylōn) was fought in 480 BC between the Achaemenid Persian Empire under Xerxes I and an alliance of Greek city-states led by Sparta under Leonidas I. Lasting over the course of three days, it was one of the most prominent battles of both the second Persian invasion of Greece and the wider Greco-Persian Wars.\n\nThe engagement at Thermopylae occurred simultaneously with the Battle of Artemisium: between July and September 480 BC. The second Persian invasion under Xerxes I was a delayed response to the failure of the first Persian invasion, which had been initiated by Darius I and ended in 490 BC by an Athenian-led Greek victory at the Battle of Marathon. By 480 BC, a decade after the Persian defeat at Marathon, Xerxes had amassed a massive land and naval force, and subsequently set out to conquer all of Greece. In response, the Athenian politician and general Themistocles proposed that the allied Greeks block the advance of the Persian army at the pass of Thermopylae while simultaneously blocking the Persian navy at the Straits of Artemisium.\n\nAround the start of the invasion, a Greek force of approximately 7,000 men led by Leonidas marched north to block the pass of Thermopylae. Ancient authors vastly inflated the size of the Persian army, with estimates in the millions, but modern scholars estimate it at between 120,000 and 300,000 soldiers. They arrived at Thermopylae by late August or early September; the outnumbered Greeks held them off for seven days (including three of direct battle) before their rear-guard was annihilated in one of history's most famous last stands. During two full days of battle, the Greeks blocked the only road by which the massive Persian army could traverse the narrow pass. After the second day, a local resident named Ephialtes revealed to the Persians the existence of a path leading behind the Greek lines. Subsequently, Leonidas, aware that his force was being outflanked by the Persians, dismissed the bulk of the Greek army and remained to guard their retreat along with 300 Spartans and 700 Thespians. It has been reported that others also remained, including up to 900 helots and 400 Thebans. With the exception of the Thebans, most of whom reportedly surrendered, the Greeks fought the Persians to the death.\n\nThemistocles was in command of the Greek naval force at Artemisium when he received news that the Persians had taken the pass at Thermopylae. Since the Greek defensive strategy had required both Thermopylae and Artemisium to be held, the decision was made to withdraw to the island of Salamis. The Persians overran Boeotia and then captured the evacuated city of Athens. The Greek fleet—seeking a decisive victory over the Persian armada—attacked and defeated the invading force at the Battle of Salamis in late 480 BC. Wary of being trapped in Europe, Xerxes withdrew with much of his army to Asia, reportedly losing many of his troops to starvation and disease while also leaving behind the Persian military commander Mardonius to continue the Achaemenid Empire's Greek campaign. However, the following year saw a Greek army decisively defeat Mardonius and his troops at the Battle of Plataea, ending the second Persian invasion.\n\nBoth ancient and modern writers have used the Battle of Thermopylae as a flagship example of the power of an army defending its native soil. The performance of the Greek defenders is also used as an example of the advantages of training, equipment, and use of terrain as force multipliers.",

        "evidence": "\nWith the wealth of information being posted online daily, Relation Extraction (RE) has become increasingly important. RE aims specifically to extract relations from raw sentences and represent them as succinct relation tuples of the form (head, relation, tail). An example is (Barack Obama, spouse, Michelle Obama).\nThe concise representations provided by RE models have been used to extend Knowledge Bases (KBs) BIBREF0, BIBREF1. These KBs are then used heavily in NLP systems, such as Task-Based Dialogue Systems. In recent years, much focus in the NRE community has been centered on improvements in model precision and the reduction of noise BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6. Yet, little attention has been devoted towards the fairness of such systems.\nIn this paper, we take the first step at understanding and evaluating gender bias in NRE systems. We analyze gender bias by measuring the differences in model performance when extracting relations from sentences written about females versus sentences written about males. Significant discrepancies in performance between genders could diminish the fairness of systems and distort outcomes in applications that use them. For example, if a model predicts the occupation relation for with higher recall for male entities, this could lead to KBs having more occupation information for males. Downstream search tasks using that KB could produce biased predictions, such as ranking articles about female computer scientists below articles about their male peers.\nWe provide the first evaluation of social bias in NRE models; specifically, we evaluate gender bias in English language predictions of a collection of popularly used and open source NRE models BIBREF2, BIBREF4, BIBREF3, BIBREF5. We evaluate OpenNRE on two fronts: (1) examining Equality of Opportunity BIBREF7 when OpenNRE is trained on an unmodified dataset and (2) examining the effect that various debiasing options BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12 have on both absolute F1 score and the difference in F1-scores on male and female datapoints.\nHowever, carrying out such an evaluation is difficult with existing NRE datasets, such as the NYT dataset from BIBREF13, because there is no reliable way to obtain gender information about the entities. Thus, we create a new dataset specifically aimed at evaluating gender bias for NRE, just as prior work has done for other tasks like Coreference Resolution BIBREF14, BIBREF9. We call our dataset WikiGenderBias and make it publicly available. Our contributions are as such:\nWikiGenderBias is the first dataset aimed at training and evaluating NRE systems for gender bias. It contains ground truth labels for the test set and about 45,000 sentences in total.\nWe provide the first evaluation of NRE systems for gender bias and find that it exhibits gender bias.\nWe demonstrate that using both gender-swapping and debiased embeddings effectively mitigates bias in the model's predictions and that using genderswapping improves the model's performance when the training data contains contextual biases.\nIn this paper, we take the first step at understanding and evaluating gender bias in NRE systems.",

Among all of the tools, the most popular and well accepted one is Domain-Specific Risk-Taking (DOSPERT) Scale BIBREF15. This is a psychometric scale that assesses risk taking in five content domains: financial decisions (separately for investing versus gambling), health/safety, recreational, ethical, and social decisions. Respondents rate the likelihood that they would engage in domain-specific risky activities (Part I). An optional Part II assesses respondents' perceptions of the magnitude of the risks and expected benefits of the activities judged in Part I. There are more scales that are used in risky behavior analysis of individual's daily activities such as, The Berlin Social Support Scales (BSSS) BIBREF16 and Values In Action Scale (VIAS) BIBREF17. Dryhootch America BIBREF18, BIBREF19, a veteran peer support community organization, chooses 5, 6 and 5 questions respectively from the above mentioned survey systems to assess the PTSD among war veterans and consider rest of them as irrelevant to PTSD. The details of dryhootch chosen survey scale are stated in Table TABREF13. Table!TABREF14 shows a sample DOSPERT scale demographic chosen by dryhootch. The threshold (in Table TABREF13) is used to calculate the risky behavior limits. For example, if one individual's weekly DOSPERT score goes over 28, he is in critical situation in terms of risk taking symptoms of PTSD. Dryhootch defines the intensity of PTSD into four categories based on the weekly survey results of all three clinical survey tools (DOSPERT, BSSS and VIAS )\nHigh risk PTSD: If one individual veteran's weekly PTSD assessment scores go above the threshold for all three PTSD assessment tools i.e. DOSPERT, BSSS and VIAS, then he/she is in high risk situation which needs immediate mental support to avoid catastrophic effect of individual's health or surrounding people's life.\nModerate risk PTSD: If one individual veteran's weekly PTSD assessment scores go above the threshold for any two of the three PTSD assessment tools, then he/she is in moderate risk situation which needs close observation and peer mentoring to avoid their risk progression.\nLow risk PTSD: If one individual veteran's weekly PTSD assessment scores go above the threshold for any one of the three PTSD assessment tools, then he/she has light symptoms of PTSD.\nNo PTSD: If one individual veteran's weekly PTSD assessment scores go below the threshold for all three PTSD assessment tools, then he/she has no PTSD.\nDryhootch defines the intensity of PTSD into four categories based on the weekly survey results of all three clinical survey tools (DOSPERT, BSSS and VIAS )\n\nHigh risk PTSD: If one individual veteran's weekly PTSD assessment scores go above the threshold for all three PTSD assessment tools i.e. DOSPERT, BSSS and VIAS, then he/she is in high risk situation which needs immediate mental support to avoid catastrophic effect of individual's health or surrounding people's life.\n\nModerate risk PTSD: If one individual veteran's weekly PTSD assessment scores go above the threshold for any two of the three PTSD assessment tools, then he/she is in moderate risk situation which needs close observation and peer mentoring to avoid their risk progression.\n\nLow risk PTSD: If one individual veteran's weekly PTSD assessment scores go above the threshold for any one of the three PTSD assessment tools, then he/she has light symptoms of PTSD.\n\nNo PTSD: If one individual veteran's weekly PTSD assessment scores go below the threshold for all three PTSD assessment tools, then he/she has no PTSD.",

Convolutional neural networks (CNNs) and recurrent neural networks (RNNs) especially Long Short-term Memory Network (LSTM), are used wildly in natural language processing tasks. With increasing datas, these two methods can reach considerable performance by requiring only limited domain knowledge and easy to be finetuned to specific applications at the same time.\nCNNs, which have the ability of capturing local correlations of spatial or temporal structures, have achieved excellent performance in computer vision and NLP tasks. And recently the emerge of some new techniques, such as Inception module BIBREF8 , Batchnorm BIBREF9 and Residual Network BIBREF3 have also made the performance even better. For sentence modeling, CNNs perform excellently in extracting n-gram features at different positions of a sentence through convolutional filters.\nRNNs, with the ability of handling sequences of any length and capturing long-term dependencies, , have also achieved remarkable results in sentence or document modeling tasks. LSTMs BIBREF10 were designed for better remembering and memory accesses, which can also avoid the problem of gradient exploding or vanishing in the standard RNN. Be capable of incorporating context on both sides of every position in the input sequence, BLSTMs introduced in BIBREF11 , BIBREF12 have reported to achieve great performance in Handwriting Recognition BIBREF13 , and Machine Translation BIBREF14 tasks.\nGenerative adversarial networks (GANs) BIBREF15 are a class of generative models for learning how to produce images. Basically, GANs consist of a generator G and a discriminator D, which are trained based on game theory. G maps a input noise vector to an output image, while D takes in an image then outputs a prediction whether the input image is a sample generated by G. Recently, applications of GANs have shown that they can generate promising results BIBREF16 , BIBREF17 . Several recent papers have also extended GANs to the semi-supervised context BIBREF18 , BIBREF19 by simply increasing the dimension of the classifier output from INLINEFORM0 to INLINEFORM1 , which the samples of the extra class are generated by G.\nIn this paper, We proposed an end-to-end architecture named AC-BLSTM by combining the ACNN with the BLSTM for sentences and documents modeling. In order to make the model deeper, instead of using the normal convolution, we apply the technique proposed in BIBREF8 which employs a INLINEFORM0 convolution followed by a INLINEFORM1 convolution by spatial factorizing the INLINEFORM2 convolution. And we use the pretrained word2vec vectors BIBREF20 as the ACNN input, which were trained on 100 billion words of Google News to learn the higher-level representations of n-grams. The outputs of the ACNN are organized as the sequence window feature to feed into the multi-layer BLSTM. So our model does not rely on any other extra domain specific knowledge and complex preprocess, e.g. word segmentation, part of speech tagging and so on. We evaluate AC-BLSTM on sentence-level and document-level tasks including sentiment analysis, question type classification, and subjectivity classification. Experimental results demonstrate the effectiveness of our approach compared with other state-of-the-art methods. Further more, inspired by the ideas of extending GANs to the semi-supervised learning context by BIBREF18 , BIBREF19 , we propose a semi-supervised learning framework for text classification which further improve the performance of AC-BLSTM.\nThe rest of the paper is organized as follows. Section 2 presents a brief review of related work. Section 3 discusses the architecture of our AC-BLSTM and our semi-supervised framework. Section 4 presents the experiments result with comparison analysis. Section 5 concludes the paper.\nFurther more, inspired by the ideas of extending GANs to the semi-supervised learning context by (Odena, 2016; Salimans et al., 2016),  we propose a semi-supervised learning framework for text classification which further improve the performance of AC-BLSTM.",

Pulse tools use oil as a medium to transfer the kinetic energy from the hammer into the anvil. This gives a smoother impulse, a slightly lower torque to weight ratio and a possibility to design a shut off mechanism that shuts the tool down when achieving the correct torque.

However, we hypothesize that various levels of linguistic annotation can be valuable for neural machine translation. Lemmatisation can reduce data sparseness, and allow inflectional variants of the same word to explicitly share a representation in the model. Other types of annotation, such as parts-of-speech (POS) or syntactic dependency labels, can help in disambiguation. In this paper we investigate whether linguistic information is beneficial to neural translation models, or whether their strong learning capability makes explicit linguistic features redundant.\nLet us motivate the use of linguistic features using examples of actual translation errors by neural MT systems. In translation out of English, one problem is that the same surface word form may be shared between several word types, due to homonymy or word formation processes such as conversion. For instance, close can be a verb, adjective, or noun, and these different meanings often have distinct translations into other languages. Consider the following English INLINEFORM0 German example:\nFor the English source sentence in Example SECREF4 (our translation in Example SECREF5 ), a neural MT system (our baseline system from Section SECREF4 ) mistranslates close as a verb, and produces the German verb schließen (Example SECREF6 ), even though close is an adjective in this sentence, which has the German translation nah. Intuitively, part-of-speech annotation of the English input could disambiguate between verb, noun, and adjective meanings of close.\nAs a second example, consider the following German INLINEFORM0 English example:\nGerman main clauses have a verb-second (V2) word order, whereas English word order is generally SVO. The German sentence (Example UID7 ; English reference in Example UID8 ) topicalizes the predicate gefährlich 'dangerous', putting the subject die Route 'the route' after the verb. Our baseline system (Example UID9 ) retains the original word order, which is highly unusual in English, especially for prose in the news domain. A syntactic annotation of the source sentence could support the attentional encoder-decoder in learning which words in the German source to attend (and translate) first.\nWe will investigate the usefulness of linguistic features for the language pair German INLINEFORM0 English, considering the following linguistic features:\nThe inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form. The other linguistic features are motivated by disambiguation, as discussed in our introductory examples.\nWe will investigate the usefulness of linguistic features for the language pair German↔English, considering the following linguistic features: The inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form.",

        "question": "What kind of people is the WEIS created by?",
        "answer": "Human coders who read news stories and coded events.",
        "evidence": "One of the defining traits of previous event-data projects is the method through which they were generated. The original datasets such as WEIS and COPDAB were created by human coders who read news stories and coded events. Future datasets such as KEDS and Phil Schrodt's Levant dataset were created using automated coding software, such as KEDS or TABARI, and news stories download from content aggregators such as Lexis Nexis or Factiva. Both pieces of coding software made use of a technique referred to as shallow parsing BIBREF13 . Shallow parsing is best understood in contrast to a deep parsing method. In deep parsing, the entire syntactic structure of a sentence is used and understood. This syntactic structure includes things such as prepositional phrases, direct and indirect objects, and other grammatical structures. A shallow parse, however, focuses solely on, as the name implies, shallow aspects such as the part of speech of the words within the sentence.\nThe second major dimension that differentiates event datasets is how news content was acquired. For WEIS and COPDAB this was as simple as subscribing to the New York Times and coding from there. Later datasets, such as those created in conjunction with the Kansas Event Data Project, obtained historical content from aggregators, as mentioned above. This difficulty of this process changed at various points in time, with something like full automation possible at some points while human downloading of stories was required at others. There are often gaps in this historical content since the content aggregators catalog of different news services changes at various points and is often fairly limited. Updating datasets based on this type of content was also fairly labor intensive since new content had to be downloaded, cleaned, and run for every update. While orders of magnitude faster than human coding, this remained an involved process.\nTaken together, these two aspects of event data generation, shallow parsing and content acquisition, form the basis for where the next generation of political event data can improve upon previous efforts. In short, a shift to deep parsing based on relatively recent advances in open-source natural language processing software, combined with realtime acquisition of news content and aggressive strategies for acquiring historical material, provide the motivation for the next generation of political event data. The following section provides greater detail regarding the implementation of these new features.\nThe original datasets such as WEIS and COPDAB were created by human coders who read news stories and coded events.",

One of the oldest QA system is BASEBALL (created on 1961) BIBREF4 which answers question related to baseball league in America for a particular season. LUNAR BIBREF5 system answers questions about soil samples taken from Apollo lunar exploration. Some of the most popular QA Systems are IBM Watson, Apple Siri and Wolfram Alpha. Examples of some QA systems based on different languages are: Zhang Yu Chinese question classification BIBREF6 based on Incremental Modified Bayes, Arabic QA system (AQAS) BIBREF7 by F. A. Mohammed, K. Nasser, & H. M. Harb and Syntactic open domain Arabic QA system for factoid questions BIBREF8 by Fareed et al. QA systems have been built on different analysis methods such as morphological analysis BIBREF9, syntactical analysis BIBREF10, semantic analysis BIBREF11 and expected answer Type analysis BIBREF12.\nResearches on question classification, question taxonomies and QA system have been undertaken in recent years. There are two types of approaches for question classification according to Banerjee et al in BIBREF13 - by rules and by machine learning approach. Rule based approaches use some hard coded grammar rules to map the question to an appropriate answer type BIBREF14 BIBREF15. Machine Learning based approaches have been used by Zhang et al and Md. Aminul Islam et al in BIBREF16 and BIBREF0. Many classifiers have been used in machine learning for QC such as Support Vector Machine (SVM) BIBREF16 BIBREF17, Support Vector Machines and Maximum Entropy Model BIBREF18, Naive Bayes (NB), Kernel Naive Bayes (KNB), Decision Tree (DT) and Rule Induction (RI) BIBREF13. In BIBREF0, they claimed to achieve average precision of 0.95562 for coarse class and 0.87646 for finer class using Stochastic Gradient Descent (SGD).\nA Bengali QC System was built by Somnath Banerjee and Sivaji Bandyopadhyay BIBREF13 BIBREF19 BIBREF20. They proposed a two-layer taxonomy classification with 9 coarse-grained classes and 69 fine-grained classes. There are other research works BIBREF0 BIBREF21 in Bengali Language. A survey was performed on text QA techniques BIBREF22 where there was an analysis conducted in Bengali Language.

There are four types of saxophones that are widely used including Soprano, Alto, Tenor, and Baritone.  Two versions, namely the Sopranino and the Bass, are produced by a very few manufacturers and are far less common and rarely used in most modern music.  The instrument is used in a variety of musical genres including classical, jazz, fusion, funk, rock and roll, R&B, Hiphop, and even country music.  Well known players of the saxophone include Charlie Parker, Cannonball Adderley, John Coltrane, Stan Getz, Sonny Stitt, Gerry Mulligan, Michael Brecker, David Sanborn, Art Pepper, Maceo Parker, Dexter Gordon, Candy Dulfer, Phil Woods, Mindi Abair, Chris Potter, Josh Redman, and many, many more.",

        "evidence": "In Yugoslavia, organized effort in machine translation started in 1959, but the first individual effort was made by Vladimir Matković from the Institute for Telecommunications in Zagreb in 1957 in his PhD thesis on entropy in the Croatian language BIBREF10. The main research group in machine translation was formed in 1958, at the Circle for Young Linguists in Zagreb, initiated by a young linguist Bulcsu Laszlo, who graduated in Russian language, Southern Slavic languages and English language and literature at the University of Zagreb in 1952. The majority of the group members came from different departments of the Faculty of Humanities and Social Sciences of the University of Zagreb, with several individuals from other institutions. The members from the Faculty of Humanities and Social Sciences were: Svetozar Petrović (Department of Comparative Literature), Stjepan Babić (Department of Serbo-Croatian Language and Literature), Krunoslav Pranjić (Department of Serbo-Croatian Language and Literature), Željko Bujas (Department of English Language and Literature), Malik Mulić (Department of Russian Language and Literature) and Bulcsu Laszlo (Department of Comparative Slavistics). The members of the research group from outside the Faculty of Humanities and Social Sciences were: Božidar Finka (Institute for Language of the Yugoslav Academy of Sciences and Arts), Vladimir Vranić (Center for Numerical Research of the Yugoslav Academy of Sciences and Arts), Vladimir Matković (Institute for Telecommunications), Vladimir Muljević (Institute for Regulatory and Signal Devices) BIBREF10.\nLaszlo and Petrović BIBREF11 also commented on the state of the art of the time, noting the USA prototype efforts from 1954 and the publication of a collection of research papers in 1955 as well as the USSR efforts starting from 1955 and the UK prototype from 1956. They do not detail or cite the articles they mention. However, the fact that they referred to them in a text published in 1959 (probably prepared for publishing in 1958, based on BIBREF11, where Laszlo and Petrović described that the group had started its work in 1958) leads us to the conclusion that the poorly funded Croatian research was lagging only a couple of years behind the research of the superpowers (which invested heavily in this effort). Another interesting moment, which they delineated in BIBREF11, is that the group soon discovered that some experimental work had already been done in 1957 at the Institute of Telecommunications (today a part of the Faculty of Electrical Engineering and Computing at the University of Zagreb) by Vladimir Matković. Because of this, they decided to include him in the research group of the Faculty of Humanities and Social Sciences at the University of Zagreb. The work done by Matković was documented in his doctoral dissertation but remained unpublished until 1959.\nThe Russian machine translation pioneer Andreev expressed hope that the Yugoslav (Croatian) research group could create a prototype, but sadly, due to the lack of federal funding, this never happened BIBREF10. Unlike their colleagues in the USA and the USSR, Laszlo’s group had to manage without an actual computer (which is painfully obvious in BIBREF12), and the results remained mainly theoretical. Appealing probably to the political circles of the time, Laszlo and Petrović note that, although it sounds strange, research in computational linguistics is mainly a top-priority military effort in other countries BIBREF11. There is a quote from BIBREF10 which perhaps best delineates the optimism and energy that the researchers in Zagreb had:\n\"[...] The process of translation has to mechanicalized as soon as possible, and this is only possible if a competent, fast and inexhaustible machine which could inherit the translation task is created, even if just schematic. The machine needs to think for us. If machines help humans in physical tasks, why would they not help them in mental tasks with their mechanical memory and automated logic\" (p. 118).\nFinka [6] notes that Matkovi´c, in his dissertation from 1957, considered the use of bigrams and trigrams to “help model the word context”.",

        "question": "What encoder and decoder does the TCEN consist of?",
        "answer": "A speech encoder, a text encoder, and a target text decoder.",
        "evidence": "Speech-to-Text translation (ST) is essential for a wide range of scenarios: for example in emergency calls, where agents have to respond emergent requests in a foreign language BIBREF0; or in online courses, where audiences and speakers use different languages BIBREF1. To tackle this problem, existing approaches can be categorized into cascaded method BIBREF2, BIBREF3, where a machine translation (MT) model translates outputs of an automatic speech recognition (ASR) system into target language, and end-to-end method BIBREF4, BIBREF5, where a single model learns acoustic frames to target word sequence mappings in one step towards the final objective of interest. Although the cascaded model remains the dominant approach due to its better performance, the end-to-end method becomes more and more popular because it has lower latency by avoiding inferences with two models and rectifies the error propagation in theory.\nSince it is hard to obtain a large-scale ST dataset, multi-task learning BIBREF5, BIBREF6 and pre-training techniques BIBREF7 have been applied to end-to-end ST model to leverage large-scale datasets of ASR and MT. A common practice is to pre-train two encoder-decoder models for ASR and MT respectively, and then initialize the ST model with the encoder of the ASR model and the decoder of the MT model. Subsequently, the ST model is optimized with the multi-task learning by weighing the losses of ASR, MT, and ST. This approach, however, causes a huge gap between pre-training and fine-tuning, which are summarized into three folds:\nSubnet Waste: The ST system just reuses the ASR encoder and the MT decoder, while discards other pre-trained subnets, such as the MT encoder. Consequently, valuable semantic information captured by the MT encoder cannot be inherited by the final ST system.\nRole Mismatch: The speech encoder plays different roles in pre-training and fine-tuning. The encoder is a pure acoustic model in pre-training, while it has to extract semantic and linguistic features additionally in fine-tuning, which significantly increases the learning difficulty.\nNon-pre-trained Attention Module: Previous work BIBREF6 trains attention modules for ASR, MT and ST respectively, hence, the attention module of ST does not benefit from the pre-training.\nTo address these issues, we propose a Tandem Connectionist Encoding Network (TCEN), which is able to reuse all subnets in pre-training, keep the roles of subnets consistent, and pre-train the attention module. Concretely, the TCEN consists of three components, a speech encoder, a text encoder, and a target text decoder. Different from the previous work that pre-trains an encoder-decoder based ASR model, we only pre-train an ASR encoder by optimizing the Connectionist Temporal Classification (CTC) BIBREF8 objective function. In this way, the additional decoder of ASR is not required while keeping the ability to read acoustic features into the source language space by the speech encoder. Besides, the text encoder and decoder can be pre-trained on a large MT dataset. After that, we employ common used multi-task learning method to jointly learn ASR, MT and ST tasks.\nCompared to prior works, the encoder of TCEN is a concatenation of an ASR encoder and an MT encoder and our model does not have an ASR decoder, so the subnet waste issue is solved. Furthermore, the two encoders work at tandem, disentangling acoustic feature extraction and linguistic feature extraction, ensuring the role consistency between pre-training and fine-tuning. Moreover, we reuse the pre-trained MT attention module in ST, so we can leverage the alignment information learned in pre-training.\nSince the text encoder consumes word embeddings of plausible texts in MT task but uses speech encoder outputs in ST task, another question is how one guarantees the speech encoder outputs are consistent with the word embeddings. We further modify our model to achieve semantic consistency and length consistency. Specifically, (1) the projection matrix at the CTC classification layer for ASR is shared with the word embedding matrix, ensuring that they are mapped to the same latent space, and (2) the length of the speech encoder output is proportional to the length of the input frame, so it is much longer than a natural sentence. To bridge the length gap, source sentences in MT are lengthened by adding word repetitions and blank tokens to mimic the CTC output sequences.\nWe conduct comprehensive experiments on the IWSLT18 speech translation benchmark BIBREF1, demonstrating the effectiveness of each component. Our model is significantly better than previous methods by 3.6 and 2.2 BLEU scores for the subword-level decoding and character-level decoding strategies, respectively.\nOur contributions are three-folds: 1) we shed light on why previous ST models cannot sufficiently utilize the knowledge learned from the pre-training process; 2) we propose a new ST model, which alleviates shortcomings in existing methods; and 3) we empirically evaluate the proposed model on a large-scale public dataset.\nConcretely, the TCEN consists of three components, a speech encoder, a text encoder, and a target text decoder.",

        "question": "What is the assumption of Zhou' s tea in their answer-aware question generation setting?",
        "answer": "Zhou et al. (2017) propose the answer-aware question generation setting which assumes the answer, a contiguous span inside the input sentence, is already known before question generation.",
        "evidence": "Question Generation (QG) is the task of automatically creating questions from a range of inputs, such as natural language text BIBREF0, knowledge base BIBREF1 and image BIBREF2. QG is an increasingly important area in NLP with various application scenarios such as intelligence tutor systems, open-domain chatbots and question answering dataset construction. In this paper, we focus on question generation from reading comprehension materials like SQuAD BIBREF3. As shown in Figure FIGREF1, given a sentence in the reading comprehension paragraph and the text fragment (i.e., the answer) that we want to ask about, we aim to generate a question that is asked about the specified answer.\nQuestion generation for reading comprehension is firstly formalized as a declarative-to-interrogative sentence transformation problem with predefined rules or templates BIBREF4, BIBREF0. With the rise of neural models, Du2017LearningTA propose to model this task under the sequence-to-sequence (Seq2Seq) learning framework BIBREF5 with attention mechanism BIBREF6. However, question generation is a one-to-many sequence generation problem, i.e., several aspects can be asked given a sentence. Zhou2017NeuralQG propose the answer-aware question generation setting which assumes the answer, a contiguous span inside the input sentence, is already known before question generation. To capture answer-relevant words in the sentence, they adopt a BIO tagging scheme to incorporate the answer position embedding in Seq2Seq learning. Furthermore, Sun2018AnswerfocusedAP propose that tokens close to the answer fragments are more likely to be answer-relevant. Therefore, they explicitly encode the relative distance between sentence words and the answer via position embedding and position-aware attention.\nAlthough existing proximity-based answer-aware approaches achieve reasonable performance, we argue that such intuition may not apply to all cases especially for sentences with complex structure. For example, Figure FIGREF1 shows such an example where those approaches fail. This sentence contains a few facts and due to the parenthesis (i.e. “the area's coldest month”), some facts intertwine: “The daily mean temperature in January is 0.3$^\\circ $C” and “January is the area's coldest month”. From the question generated by a proximity-based answer-aware baseline, we find that it wrongly uses the word “coldest” but misses the correct word “mean” because “coldest” has a shorter distance to the answer “0.3$^\\circ $C”.\nIn summary, their intuition that “the neighboring words of the answer are more likely to be answer-relevant and have a higher chance to be used in the question” is not reliable. To quantitatively show this drawback of these models, we implement the approach proposed by Sun2018AnswerfocusedAP and analyze its performance under different relative distances between the answer and other non-stop sentence words that also appear in the ground truth question. The results are shown in Table TABREF2. We find that the performance drops at most 36% when the relative distance increases from “$0\\sim 10$” to “$>10$”. In other words, when the useful context is located far away from the answer, current proximity-based answer-aware approaches will become less effective, since they overly emphasize neighboring words of the answer.\nTo address this issue, we extract the structured answer-relevant relations from sentences and propose a method to jointly model such structured relation and the unstructured sentence for question generation. The structured answer-relevant relation is likely to be to the point context and thus can help keep the generated question to the point. For example, Figure FIGREF1 shows our framework can extract the right answer-relevant relation (“The daily mean temperature in January”, “is”, “32.6$^\\circ $F (0.3$^\\circ $C)”) among multiple facts. With the help of such structured information, our model is less likely to be confused by sentences with a complex structure. Specifically, we firstly extract multiple relations with an off-the-shelf Open Information Extraction (OpenIE) toolbox BIBREF7, then we select the relation that is most relevant to the answer with carefully designed heuristic rules.\nNevertheless, it is challenging to train a model to effectively utilize both the unstructured sentence and the structured answer-relevant relation because both of them could be noisy: the unstructured sentence may contain multiple facts which are irrelevant to the target question, while the limitation of the OpenIE tool may produce less accurate extracted relations. To explore their advantages simultaneously and avoid the drawbacks, we design a gated attention mechanism and a dual copy mechanism based on the encoder-decoder framework, where the former learns to control the information flow between the unstructured and structured inputs, while the latter learns to copy words from two sources to maintain the informativeness and faithfulness of generated questions.\nIn the evaluations on the SQuAD dataset, our system achieves significant and consistent improvement as compared to all baseline methods. In particular, we demonstrate that the improvement is more significant with a larger relative distance between the answer and other non-stop sentence words that also appear in the ground truth question. Furthermore, our model is capable of generating diverse questions for a single sentence-answer pair where the sentence conveys multiple relations of its answer fragment.\nZhou et al. (2017) propose the answer-aware question generation setting which assumes the answer, a contiguous span inside the input sentence, is already known before question generation.",

It communicates through NASA's Deep Space Network to receive routine commands and to transmit data to Earth. Real-time distance and velocity data is provided by NASA and JPL. At a distance of 159.20 AU (23.816 billion km; 14.799 billion mi) from Earth as of March 27, 2023, it is the most distant human-made object from Earth.\n\nThe probe made flybys of Jupiter, Saturn, and Saturn's largest moon, Titan. NASA had a choice of either doing a Pluto or Titan flyby; exploration of the moon took priority because it was known to have a substantial atmosphere. Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons.\n\nAs part of the Voyager program and like its sister craft Voyager 2, the spacecraft's extended mission is to locate and study the regions and boundaries of the outer heliosphere and to begin exploring the interstellar medium. Voyager 1 crossed the heliopause and entered interstellar space on August 25, 2012, making it the first spacecraft to do so. Two years later, Voyager 1 began experiencing a third \"tsunami wave\" of coronal mass ejections from the Sun that continued to at least December 15, 2014, further confirming that the probe is indeed in interstellar space.\n\nIn a further testament to the robustness of Voyager 1, the Voyager team tested the spacecraft's trajectory correction maneuver (TCM) thrusters in late 2017 (the first time these thrusters had been fired since 1980), a project enabling the mission to be extended by two to three years.

        "evidence": "In seeking to answer the question of whether the occupancy rate of a listing could be extracted from the listing’s summary, we ran a number of experiments on our first model. Two parameterizations which we present here are (1) whether the word vectors used in the embedding layer are trained on our corpus or come pretrained from Wikipedia and Gigaword and (2) whether ensembling or the final hidden state in isolation are used to make a prediction for the sequence. Common to all experiments was our decision to use an Adam optimizer, 16 LSTM units, 50-dimensional GloVe vectors, and a 70-30 split in train and test data.\nOver ten epochs, the model parameterization which performs the best uses GloVe vectors trained on a corpus consisting of all listing descriptions and ensembling to make its class prediction. As a result, our findings are well in-line with those presented by Radford et. al who underscore the importance of training word embeddings on a data-specific corpus for best results on generative tasks [9].\nThat said, these results, though they do show a marginal increase in dev accuracy and a decrease in CE loss, suggest that perhaps listing description is not too predictive of occupancy rate given our parameterizations. While the listing description is surely an influential metric in determining the quality of a listing, other factors such as location, amenities, and home type might play a larger role in the consumer's decision. We were hopeful that these factors would be represented in the price per bedroom of the listing – our control variable – but the relationship may not have been strong enough.\nHowever, should a strong relationship actually exist and there be instead a problem with our method, there are a few possibilities of what went wrong. We assumed that listings with similar occupancy rates would have similar listing descriptions regardless of price, which is not necessarily a strong assumption. This is coupled with an unexpected sparseness of clean data. With over 40,000 listings, we did not expect to see such poor attention to orthography in what are essentially public advertisements of the properties. In this way, our decision to use a window size of 5, a minimum occurrence count of 2, and a dimensionality of 50 when training our GloVe vectors was ad hoc.\nSeeking to create a model which could generate and discriminate a “high-occupancy listing description”, we wanted to evaluate the capabilities of a generative adversarial network trained on either the standard binary cross-entropy loss or the DMK loss proposed above. Common to both models was the decision to alternate between training the generator for 50 steps and the discriminator for 2000 steps. We leave further tuning of the models to future research as each occasionally falls into unideal local optima within 20 iterations. One potential culprit is the step imbalance between generator and discriminator – should either learn at a much faster rate than the other, one component is liable to be “defeated\" and cease to learn the training data.\nQualitatively the network trained on the DMK loss shows great promise. With respect to the two experiments presented here, we have shown that it is possible to introduce a measure of suggestion in the text produced by the generator. While this model is also subject to a rapid deadlock between generator and discriminator, it is interesting to see how the introduction of keywords is gradual and affects the proximal tokens included in the output. This behavior was made possible by paying close attention to the hyperparameter $\\gamma $ , the weight given to the dot product attention term of the DMK loss. After manual tuning, we settle on $\\gamma =0.00045$ for this weight. Below, we illustrate model outputs using different values of Gamma. As is apparent, for a hyper-parameter value less than roughly $\\gamma = 0.0004$ , the model tends to ignore the importance of the keyword weights. Conversely, with a $\\gamma $ value higher than $0.0005$ , the model tends towards overweighting the representation of the keywords in the model output.\nIn seeking to answer the question of whether the occupancy rate of a listing could be extracted from the listings summary, we ran a number of experiments on our first model.

However, the output generated can be repetitive and generic leading to monotonous or uninteresting responses (e.g “I don't know”) regardless of the input BIBREF1. While application of attention BIBREF2, BIBREF3 and advanced decoding mechanisms like beam search and variation sampling BIBREF4 have shown improvements, it does not solve the underlying problem. In creative text generation, the objective is not strongly bound to the ground truth—instead the objective is to generate diverse, unique or original samples. We attempt to do this through a discriminator which can give feedback to the generative model through a cost function that encourages sampling of creative tokens. The contributions of this paper are in the usage of a GAN framework to generate creative pieces of writing. Our experiments suggest that generative text models, while very good at encapsulating semantic, syntactic and domain information, perform better with external feedback from a discriminator for fine-tuning objectiveless decoding tasks like that of creative text. We show this by evaluating our model on three very different creative datasets containing poetry, metaphors and lyrics.\nPrevious work on handling the shortcomings of MLE include length-normalizing sentence probability BIBREF5, future cost estimation BIBREF6, diversity-boosting objective function BIBREF7, BIBREF1 or penalizing repeating tokens BIBREF8. When it comes to poetry generation using generative text models, Zhang and Lapata BIBREF9, Yi et al. BIBREF10 and Wang et al. BIBREF11 use language modeling to generate Chinese poems. However, none of these methods provide feedback on the quality of the generated sample and hence, do not address the qualitative objective required for creative decoding. For the task of text generation, MaskGAN BIBREF12 uses a Reinforcement Learning signal from the discriminator, FMD-GAN BIBREF13 uses an optimal transport mechanism as an objective function. GumbelGAN BIBREF14 uses Gumbel-Softmax distribution that replaces the non-differentiable sample from a categorical distribution with a differentiable sample to propagate stronger gradients. Li et al. BIBREF1 use a discriminator for a diversity promoting objective. Yu et al. BIBREF15 use SeqGAN to generate poetry and comment on the performance of SeqGAN over MLE in human evaluations, encouraging our study of GANs for creative text generation. However, these studies do not focus solely on creative text.\nUsing GANs, we can train generative models in a two-player game setting between a discriminator and a generator, where the discriminator (a binary classifier) learns to distinguish between real and fake data samples and the generator tries to fool the discriminator by generating authentic and high quality output.",

To this end, we introduce a binary vector $\\tilde{x} \\in \\mathbb {R}^{V} $ whose entries are equal to one when the corresponding word from the vocabulary is present in the document and zero otherwise (i.e. $\\tilde{x}$ is a binary bag-of-words representation of the document). Thereafter, we build the document summary vector $d$ component-wise, so that $d$ is just a vector of word relevances:\nNote that the BoW/SVM model being a linear predictor relying directly on word frequency statistics, it lacks expressive power in comparison to the CNN model which additionally learns intermediate hidden layer representations and convolutional filters. Moreover the CNN model can take advantage of the semantic similarity encoded in the distributed word2vec representations, while for the BoW/SVM model all words are “equidistant” in the bag-of-words semantic space",

        "evidence": "\nAntisocial behavior. Antisocial behavior online comes in many forms, including harassment BIBREF30, cyberbullying BIBREF31, and general aggression BIBREF32. Prior work has sought to understand different aspects of such behavior, including its effect on the communities where it happens BIBREF33, BIBREF34, the actors involved BIBREF35, BIBREF36, BIBREF37, BIBREF38 and connections to the outside world BIBREF39.\nPost-hoc classification of conversations. There is a rich body of prior work on classifying the outcome of a conversation after it has concluded, or classifying conversational events after they happened. Many examples exist, but some more closely related to our present work include identifying the winner of a debate BIBREF40, BIBREF41, BIBREF42, identifying successful negotiations BIBREF21, BIBREF43, as well as detecting whether deception BIBREF44, BIBREF45, BIBREF46 or disagreement BIBREF47, BIBREF48, BIBREF49, BIBREF50, BIBREF51 has occurred.\nOur goal is different because we wish to forecast conversational events before they happen and while the conversation is still ongoing (potentially allowing for interventions). Note that some post-hoc tasks can also be re-framed as forecasting tasks (assuming the existence of necessary labels); for instance, predicting whether an ongoing conversation will eventually spark disagreement BIBREF18, rather than detecting already-existing disagreement.\nConversational forecasting. As described in Section SECREF1, prior work on forecasting conversational outcomes and events has largely relied on hand-crafted features to capture aspects of conversational dynamics. Example feature sets include statistical measures based on similarity between utterances BIBREF16, sentiment imbalance BIBREF20, flow of ideas BIBREF20, increase in hostility BIBREF8, reply rate BIBREF11 and graph representations of conversations BIBREF52, BIBREF17. By contrast, we aim to automatically learn neural representations of conversational dynamics through pre-training.\nSuch hand-crafted features are typically extracted from fixed-length windows of the conversation, leaving unaddressed the problem of unknown horizon. While some work has trained multiple models for different window-lengths BIBREF8, BIBREF18, they consider these models to be independent and, as such, do not address the issue of aggregating them into a single forecast (i.e., deciding at what point to make a prediction). We implement a simple sliding windows solution as a baseline (Section SECREF5).\nPre-training for NLP. The use of pre-training for natural language tasks has been growing in popularity after recent breakthroughs demonstrating improved performance on a wide array of benchmark tasks BIBREF53, BIBREF54. Existing work has generally used a language modeling objective as the pre-training objective; examples include next-word prediction BIBREF55, sentence autoencoding, BIBREF56, and machine translation BIBREF57. BERT BIBREF58 introduces a variation on this in which the goal is to predict the next sentence in a document given the current sentence. Our pre-training objective is similar in spirit, but operates at a conversation level, rather than a document level. We hence view our objective as conversational modeling rather than (only) language modeling. Furthermore, while BERT's sentence prediction objective is framed as a multiple-choice task, our objective is framed as a generative task.\n\nConversational forecasting. As described in Section 1, prior work on forecasting conversational outcomes and events has largely relied on handcrafted features to capture aspects of conversational dynamics.",

ELMo (Embeddings from Language Models) embedding BIBREF3 is one of the state-of-the-art pretrained transfer learning models, that remedies the problem and introduces a contextual component.\nELMo model`s architecture consists of three neural network layers. The output of the model after each layer gives one set of embeddings, altogether three sets. The first layer is a CNN layer, which operates on a character level. It is context independent, so each word always gets the same embedding, regardless of its context. It is followed by two biLM layers. A biLM layer consists of two concatenated LSTMs. In the first LSTM, we try to predict the following word, based on the given past words, where each word is represented by the embeddings from the CNN layer. In the second LSTM, we try to predict the preceding word, based on the given following words. It is equivalent to the first LSTM, just reading the text in reverse.\nIn NLP tasks, any set of these embeddings may be used; however, a weighted average is usually used. The weights of the average are learned during the training of the model for the specific task. Additionally, an entire ELMo model can be fine-tuned on a specific end task.\nAlthough ELMo is trained on character level and is able to handle out-of-vocabulary words, a vocabulary file containing most common tokens is used for efficiency during training and embedding generation.

        "evidence": "Language modeling is a probabilistic description of language phenomenon. It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nWe also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language.",

Our encoder first reads the text, and the results from the first read help represent the text in the second pass over the source text.

        "evidence": "",
        "answer": "Henry Ford (July 30, 1863 – April 7, 1947) was an American industrialist and business magnate. He was the founder of Ford Motor Company, and chief developer of the assembly line technique of mass production. Ford created the first automobile that middle-class Americans could afford, and his conversion of the automobile from an expensive luxury into an accessible conveyance profoundly impacted the landscape of the 20th century.\n\nFord was born on a farm in Michigan's Springwells Township to a Belgian family, leaving home at age 16 to work in Detroit. It was a few years before this time that Ford first experienced automobiles, and throughout the later half of the 1880s, Ford began repairing and later constructing engines, and through the 1890s worked with a division of Edison Electric. He officially founded Ford Motor Company in 1903, after prior failures in business but success in constructing automobiles.\n\nFord's 1908 introduction of the Model T automobile revolutionized both transportation and American industry. As the Ford Motor Company sole owner, he became one of the richest and best-known people in the world. He is credited with \"Fordism\", the mass production of inexpensive goods coupled with high wages for workers. Ford was also among the pioneers of the five-day work week. Ford had a global vision, with consumerism as the key to peace. His intense commitment to systematically lowering costs resulted in many technical and business innovations, including a franchise system that put dealerships throughout North America and major cities on six continents.\n\nFord was widely known for his pacifism during the first years of World War I. In the 1920s Ford promoted antisemitic content through his newspaper The Dearborn Independent, and the book, The International Jew. After his son Edsel died in 1943, Ford resumed control of the company but was too frail to make decisions and quickly came under the control of subordinates. He turned over the company to his grandson Henry Ford II in 1945. He died in 1947 after leaving most of his wealth to the Ford Foundation, and control of the company to his family.",

        "evidence": "",
        "answer": "There are a series of factors when considering to purchase a tennis racquets.  Primary factors include head size, length, weight, stiffness, and swingweight  \n\nHead size - Power is closely correlated to head size - the larger the head size, the more power can be generated, all other factors being equal.  A larger head size also provides larger hitting area and 'sweetspot'.  Smaller head sizes tend to equate to more control and maneuverability. \n\nLength - The standard length is a 27 inches, but can range from 26.5 inches to 29 inches.  A longer racquets provides more reach and often results in more power.  Similar to head size, longer racquets may limit maneuverability and control. \n\nWeight - The heavier the racquet, the more power you will generate (increasing the 'swingweight') of the racquet.  The lighter the racquet, the more maneuverable and easier it will be for players to get the racket to the right swing position.  The balance of the racquet is also critical as part of weight.  A more head light racket (more weight in the handle) provides increased maneuverability, especially when using a heavier racquet. A more balanced or head heavy racket are often reserved for lighter racquets to maintain the mass behind the ball\n\nStiffness - Generally speaking, the stiffer the racket, the less energy is lost as the ball is redirected with your racquet and thus, creating more power.  More flexible racquets allow for more feel and control.  Flexible racquets provide more comfort as less shock and impact is transferred to the arm and elbow.\n\nSwingweight - Swingweight measures how heavy a racquet feels when you swing it and the amount of power you can transfer to the ball.  Higher swingweight will also provide more stability in the racquet but will sacrifice maneuverability.",

        "question": "How many SQA models (QANets) does the proposed approach have?",
        "answer": "Two SQA models (QANets).",
        "evidence": "The main focus of this paper is to apply domain adaptation for SQA. In this approach, we have two SQA models (QANets), one trained from target domain data (ASR hypotheses) and another trained from source domain data (reference transcriptions). Because the two domains share common information, some layers in these two models can be tied in order to model the shared features. Hence, we can choose whether each layer in the QA model should be shared. Tying the weights between the source layer and the target layer in order to learn a symmetric mapping is to project both source and target domain data to a shared common space. Different combinations will be investigated in our experiments.\nMore specifically, we incorporate a domain discriminator into the SQA model shown in Figure FIGREF2 , which can enforce the embedding encoder to project the sentences from both source and target domains into a shared common space and consequentially to be ASR-error robust. Although the embedding encoder for both domains may implicitly learn some common latent representations, adversarial learning can provide a more direct training signal for aligning the output distribution of the embedding encoder from both domains. The embedding encoder takes in a sequence of word vectors and generates a sequence of hidden vectors with the same length. We use INLINEFORM0 and INLINEFORM1 ( INLINEFORM2 and INLINEFORM3 ) to represent the hidden vector sequence given the question INLINEFORM4 and the document INLINEFORM5 in the target (source) domain respectively.\nThe domain discriminator INLINEFORM0 focuses on identifying the domain of the vector sequence is from given INLINEFORM1 or INLINEFORM2 , where the objective is to minimize INLINEFORM3 . DISPLAYFORM0 \nGiven a training example from the target domain ( INLINEFORM0 ), INLINEFORM1 learns to assign a lower score to INLINEFORM2 and INLINEFORM3 in that example, that is, to minimize INLINEFORM4 and INLINEFORM5 . On the other hand, given a training example from the source domain ( INLINEFORM6 ), INLINEFORM7 learns to assign a larger value to INLINEFORM8 and INLINEFORM9 .\nFurthermore, we update the parameters of the embedding encoders to maximize the domain classification loss INLINEFORM0 , which works adversarially towards the domain discriminator. We thus expect the model to learn features and structures that can generalize across domains when the outputs of INLINEFORM1 are indistinguishable from the outputs of INLINEFORM2 . The loss function for embedding encoder, INLINEFORM3 , is formulated as DISPLAYFORM0 \nwhere INLINEFORM0 is a hyperparameter. The two embedding encoders in the QA model are learned to maximize INLINEFORM1 while minimizing the loss for QA, INLINEFORM2 . Because the parameters of other layers in QA model are independent to the loss of the domain discriminator, the loss function of other layers, INLINEFORM3 , is equivalent to INLINEFORM4 , that is, INLINEFORM5 .\nAlthough the discriminator is applied to the output of embedding encoder in Figure FIGREF2 , it can be also applied to other layers. Considering that almost all QA model contains such embedding encoders, the proposed approach is expected to generalize to other QA models in addition to QANet.\nIn this approach, we have two SQA models (QANets), one trained from target domain data (ASR hypotheses) and another trained from source domain data (reference transcrip tions).",

However, the NL output would contain redundant information and consequently sound very artificial. Thus, the goal is to transform the generated description to sound more natural. To this end, we focus on two types of transformation rules (cf. BIBREF21): ordering and clustering and grouping. In the following, we describe the transformation rules we employ in more detail. Note that clustering and ordering (SECREF18) is applied before grouping (SECREF26).\nWe process the input trees in descending order with respect to the frequency of the variables they contain, starting with the projection variables and only after that turning to other variables. As an example, consider the following triples about two of the most known people in the world:\nThe five triples are verbalized as given in UNKREF20–UNKREF24. Clustering and ordering first take all sentences containing the subject :Albert_Einstein, i.e. UNKREF21 –UNKREF23, which are ordered such that copulative sentences (such as Albert Einstein is a scientist) come before other sentences, and then takes all sentences containing the remaining subject :William_Shakespeare in UNKREF20 and UNKREF24 resulting in a sequence of sentences as in UNKREF25.\nWilliam Shakespeare is a writer.\nAlbert Einstein's birth place is Ulm.\nAlbert Einstein's death place is Princeton.\nAlbert Einstein is a scientist.\nWilliam Shakespeare's death date is 23 April 1616.\nAlbert Einstein is a scientist.

William Shakespeare's death date is 23 April 1616.\ndalianishovy describe grouping as a process “collecting clauses with common elements and then collapsing the common elements”. The common elements are usually subject noun phrases and verb phrases (verbs together with object noun phrases), leading to subject grouping and object grouping. To maximize the grouping effects, we collapse common prefixes and suffixes of sentences, irrespective of whether they are full subject noun phrases or complete verb phrases. In the following we use $X_1,X_2,$...$X_N$ as variables for the root nodes of the input sentences and $Y$ as variable for the root node of the output sentence.

        "question": "What problems do the authors consider?",
        "answer": "The authors consider the problem of learning the structure and parameters of scripts in the form of HMMs from sequences of natural language sentences.",
        "evidence": " Scripts were developed as a means of representing stereotypical event sequences and interactions in narratives. The benefits of scripts for encoding common sense knowledge, filling in gaps in a story, resolving ambiguous references, and answering comprehension questions have been amply demonstrated in the early work in natural language understanding BIBREF0 . The earliest attempts to learn scripts were based on explanation-based learning, which can be characterized as example-guided deduction from first principles BIBREF1 , BIBREF2 . While this approach is successful in generalizing from a small number of examples, it requires a strong domain theory, which limits its applicability.\nMore recently, some new graph-based algorithms for inducing script-like structures from text have emerged. “Narrative Chains” is a narrative model similar to Scripts BIBREF3 . Each Narrative Chain is a directed graph indicating the most frequent temporal relationship between the events in the chain. Narrative Chains are learned by a novel application of pairwise mutual information and temporal relation learning. Another graph learning approach employs Multiple Sequence Alignment in conjunction with a semantic similarity function to cluster sequences of event descriptions into a directed graph BIBREF4 . More recently still, graphical models have been proposed for representing script-like knowledge, but these lack the temporal component that is central to this paper and to the early script work. These models instead focus on learning bags of related events BIBREF5 , BIBREF6 .\nWhile the above approches demonstrate the learnability of script-like knowledge, they do not offer a probabilistic framework to reason robustly under uncertainty taking into account the temporal order of events. In this paper we present the first formal representation of scripts as Hidden Markov Models (HMMs), which support robust inference and effective learning algorithms. The states of the HMM correspond to event types in scripts, such as entering a restaurant or opening a door. Observations correspond to natural language sentences that describe the event instances that occur in the story, e.g., “John went to Starbucks. He came back after ten minutes.” The standard inference algorithms, such as the Forward-Backward algorithm, are able to answer questions about the hidden states given the observed sentences, for example, “What did John do in Starbucks?”\nThere are two complications that need to be dealt with to adapt HMMs to model narrative scripts. First, both the set of states, i.e., event types, and the set of observations are not pre-specified but are to be learned from data. We assume that the set of possible observations and the set of event types to be bounded but unknown. We employ the clustering algorithm proposed in BIBREF4 to reduce the natural language sentences, i.e., event descriptions, to a small set of observations and states based on their Wordnet similarity.\nThe second complication of narrative texts is that many events may be omitted either in the narration or by the event extraction process. More importantly, there is no indication of a time lapse or a gap in the story, so the standard forward-backward algorithm does not apply. To account for this, we allow the states to skip generating observations with some probability. This kind of HMMs, with insertions and gaps, have been considered previously in speech processing BIBREF7 and in computational biology BIBREF8 . We refine these models by allowing state-dependent missingness, without introducing additional “insert states” or “delete states” as in BIBREF8 . In this paper, we restrict our attention to the so-called “Left-to-Right HMMs” which have acyclic graphical structure with possible self-loops, as they support more efficient inference algorithms than general HMMs and suffice to model most of the natural scripts. We consider the problem of learning the structure and parameters of scripts in the form of HMMs from sequences of natural language sentences. Our solution to script learning is a novel bottom-up method for structure learning, called SEM-HMM, which is inspired by Bayesian Model Merging (BMM) BIBREF9 and Structural Expectation Maximization (SEM) BIBREF10 . It starts with a fully enumerated HMM representation of the event sequences and incrementally merges states and deletes edges to improve the posterior probability of the structure and the parameters given the data. We compare our approach to several informed baselines on many natural datasets and show its superior performance. We believe our work represents the first formalization of scripts that supports probabilistic inference, and paves the way for robust understanding of natural language texts.\nWe consider the problem of learning the structure and parameters of scripts in the form of HMMs from sequences of natural language sentences.",

Those estimates were criticised by Tim Dyson, who considers them exaggerations.

By 1700, Mughal India had an urban population of 23 million people, larger than British India's urban population of 22.3 million in 1871. Nizamuddin Ahmad (1551–1621) reported that, under Akbar's reign, Mughal India had 120 large cities and 3,200 townships. A number of cities in India had a population between a quarter-million and half-million people, with larger cities including Agra (in Agra Subah) with up to 800,000 people and Dhaka (in Bengal Subah) with over 1 million people.

        "answer": "Yes, it is.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nTherefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not.",

To compute, $A(\\ell )$ in this manner we first pad the sequence length $T$ out to the nearest power of two, and then compute a balanced parallel tree over the parts, shown in Figure FIGREF21.

In terms of this, rather than starting from Twitter API Search, we look into the archived snapshots of two major news websites (CNN, NBC), and then extract the tweet blocks that are embedded in the news articles. In order to get enough data, we first extract the URLs of all section pages (e.g. World, Politics, Money, Tech) from the snapshot of each home page and then crawl all articles with tweets from these section pages. Note that another possible way to collect informative tweets is to download the tweets that are posted by the official Twitter accounts of news media. However, these tweets are often just the summaries of news articles, which are written in formal text. As our focus is to develop a dataset for QA on informal social media text, we do not consider this approach.\nAfter we extracted tweets from archived news articles, we observed that there is still a portion of tweets that have very simple semantic structures and thus are very difficult to raise meaningful questions. An example of such tweets can be like: “Wanted to share this today - @IAmSteveHarvey\". This tweet is actually talking about an image attached to this tweet. Some other tweets with simple text structures may talk about an inserted link or even videos. To filter out these tweets that heavily rely on attached media to convey information, we utilize a state-of-the-art semantic role labeling model trained on CoNLL-2005 BIBREF15 to analyze the predicate-argument structure of the tweets collected from news articles and keep only the tweets with more than two labeled arguments. This filtering process also automatically filters out most of the short tweets. For the tweets collected from CNN, INLINEFORM0 of them were filtered via semantic role labeling. For tweets from NBC, INLINEFORM1 of the tweets were filtered.\nWe then use Amazon Mechanical Turk to collect question-answer pairs for the filtered tweets. For each Human Intelligence Task (HIT), we ask the worker to read three tweets and write two question-answer pairs for each tweet. To ensure the quality, we require the workers to be located in major English speaking countries (i.e. Canada, US, and UK) and have an acceptance rate larger than INLINEFORM0 . Since we use tweets as context, lots of important information are contained in hashtags or even emojis. Instead of only showing the text to the workers, we use javascript to directly embed the whole tweet into each HIT. This gives workers the same experience as reading tweets via web browsers and help them to better compose questions.\nTo avoid trivial questions that can be simply answered by superficial text matching methods or too challenging questions that require background knowledge. We explicitly state the following items in the HIT instructions for question writing:\nNo Yes-no questions should be asked.\nThe question should have at least five words.\nVideos, images or inserted links should not be considered.\nNo background knowledge should be required to answer the question.\nTo help the workers better follow the instructions, we also include a representative example showing both good and bad questions or answers in our instructions. Figure FIGREF14 shows the example we use to guide the workers.\nAs for the answers, since the context we consider is relatively shorter than the context of previous datasets, we do not restrict the answers to be in the tweet, otherwise, the task may potentially be simplified as a classification problem. The workers are allowed to write their answers in their own words. We just require the answers to be brief and can be directly inferred from the tweets.\nAfter we retrieve the QA pairs from all HITs, we conduct further post-filtering to filter out the pairs from workers that obviously do not follow instructions. We remove QA pairs with yes/no answers. Questions with less than five words are also filtered out. This process filtered INLINEFORM0 of the QA pairs. The dataset now includes 10,898 articles, 17,794 tweets, and 13,757 crowdsourced question-answer pairs. The collected QA pairs will be directly available to the public, and we will provide a script to download the original tweets and detailed documentation on how we build our dataset. Also note that since we keep the original news article and news titles for each tweet, our dataset can also be used to explore more challenging generation tasks. Table TABREF19 shows the statistics of our current collection, and the frequency of different types of questions is shown in Table TABREF21 . All QA pairs were written by 492 individual workers.\nFor the purposes of human performance evaluation and inter-annotator agreement checking, we launch a different set of HITs to ask workers to answer questions in the test and development set. The workers are shown with the tweet blocks as well as the questions collected in the previous step. At this step, workers are allowed to label the questions as “NA\" if they think the questions are not answerable. We find that INLINEFORM0 of the questions are labeled as unanswerable by the workers (for SQuAD, the ratio is INLINEFORM1 ). Since the answers collected at this step and previous step are written by different workers, the answers can be written in different text forms even they are semantically equal to each other. For example, one answer can be “Hillary Clinton” while the other is “@HillaryClinton”. As it is not straightforward to automatically calculate the overall agreement, we manually check the agreement on a subset of 200 random samples from the development set and ask an independent human moderator to verify the result. It turns out that INLINEFORM2 of the answers pairs are semantically equivalent, INLINEFORM3 of them are partially equivalent (one of them is incomplete) and INLINEFORM4 are totally inconsistent. The answers collected at this step are also used to measure the human performance. We have 59 individual workers participated in this process.\nOne major challenge of building a QA dataset on tweets is the sparsity of informative tweets.",

Depending on what you are making and what you are looking for from a taste perspective there are several options for you to substitute eggs. \n\nSilken Tofu - If you are making a vegan scramble, quiche, or homemade vegan mayonnaise. The creamy texture can help mimic the egg’s soft texture in your breakfast meals and desserts.\nUnsweetened applesauce - You can use a quarter cup of unsweetened applesauce for one egg. It adds moisture and sweetness to what you are making. The natural fruit pectin also helps bind the ingredients. It can be dense than an egg in your baking so you may need to use a teaspoon of baking powder to encourage fluffiness. \nMashed banana - This has a very distinct flavor, so only use it in recipes when you think the banana flavor will complement what you are making. This works well in pancakes, brownies, and banana bread. You can use a ripe medium mashed banana for every large egg. The starches and sugars in the banana help develop a beautiful golden brown crust. \nAquafaba - This is an ideal substitute for egg whites, giving your dessert structure. Take three tablespoons of liquid from inside your can of chickpeas and whip them to a fluffy consistency. \nFlaxseeds or Chia Seeds - This is best for recipes that don’t require too many eggs. Combine one tablespoon of seeds with three tablespoons of water for every large egg. Let it sit for 20 minutes to get a slimy mixture that mimics and egg.\nBaking Soda and Vinegar - Mix a teaspoon of baking soda and a tablespoon of white vinegar together to help create the air bubbles needed in things like pancakes, cookies, and quick breads.

Customs vary between cultures and religious groups. Funerals have both normative and legal components. Common secular motivations for funerals include mourning the deceased, celebrating their life, and offering support and sympathy to the bereaved; additionally, funerals may have religious aspects that are intended to help the soul of the deceased reach the afterlife, resurrection or reincarnation.\n\nThe funeral usually includes a ritual through which the corpse receives a final disposition. Depending on culture and religion, these can involve either the destruction of the body (for example, by cremation or sky burial) or its preservation (for example, by mummification or interment). Differing beliefs about cleanliness and the relationship between body and soul are reflected in funerary practices. A memorial service (or celebration of life) is a funerary ceremony that is performed without the remains of the deceased person.\n\nThe word funeral comes from the Latin funus, which had a variety of meanings, including the corpse and the funerary rites themselves.

These people could be underprivileged because of several factors: ethnicity, religion, colour, language, nationality, gender, etc. The other people who do not come under the underprivileged section are the normal people.\n\nThe underprivileged people suffer major struggles in their life over decades or sometime over centuries. On the social development indices such as literacy, life expectancy, incarceration, health conditions, etc.. the underprivileged people lag behind the normal people significantly. Examples of underprivileged people include the indigenous people in many countries such as Australia, New Zealand, Canada, USA and also the people of African descent in the USA. \n\nThe people from the underprivileged communities have to brought into the mainstream and in order to achieve this objective,  the required job and career opportunities have to be created. Education is a powerful tool to equip the people to gain the skills required to perform the roles. These people have been deprived of education for a long time and so the governments and the social leaders have to take the initiatives to extend education to the underprivileged. There has to be a concerted effort over a long time, some times for even 50 to 100 years, to improve the skill levels of the underprivileged people by focusing on education and training.\n\nThe underprivileged people have to be empowered citizens of the society. In order to enable these people to overcome the handicap of the suppression they have suffered for a long time, leaders from these communities have to be involved in the decision making and governance forums in the society.  As an example, in Indian Parliament around 24% of the seats are reserved only for people from the underprivileged sections to contest and get elected to become members of the parliament. Using this model to reserve seats for the. underprivileged in the governance bodies, we can provide opportunity for the underprivileged to participate in the governance and enact laws that will protect their interests. \n\nA combination of education and empowerment would go a long way in improving the life of the underprivileged people in the society.",

        "question": "What is the objective of a batter in the sport of baseball?",
        "evidence": "Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called \"runs\". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter).\n\nThe principal objective of the batting team is to have a player reach first base safely; this generally occurs either when the batter hits the ball and reaches first base before an opponent retrieves the ball and touches the base, or when the pitcher persists in throwing the ball out of the batter's reach. Players on the batting team who reach first base without being called \"out\" can attempt to advance to subsequent bases as a runner, either immediately or during teammates' turns batting. The fielding team tries to prevent runs by getting batters or runners \"out\", which forces them out of the field of play. The pitcher can get the batter out by throwing three pitches which result in strikes, while fielders can get the batter out by catching a batted ball before it touches the ground, and can get a runner out by tagging them with the ball while the runner is not touching a base.\n\nThe opposing teams switch back and forth between batting and fielding; the batting team's turn to bat is over once the fielding team records three outs. One turn batting for each team constitutes an inning. A game is usually composed of nine innings, and the team with the greater number of runs at the end of the game wins. Most games end after the ninth inning, but if scores are tied at that point, extra innings are usually played. Baseball has no game clock, though some competitions feature pace-of-play regulations such as the pitch clock to shorten game time.\n\nBaseball evolved from older bat-and-ball games already being played in England by the mid-18th century. This game was brought by immigrants to North America, where the modern version developed. Baseball's American origins, as well as its reputation as a source of escapism during troubled points in American history such as the American Civil War and the Great Depression, have led the sport to receive the moniker of \"America's Pastime\"; since the late 19th century, it has been unofficially recognized as the national sport of the United States, though in modern times is considered less popular than other sports, such as American football. In addition to North America, baseball is considered the most popular sport in parts of Central and South America, the Caribbean, and East Asia, particularly in Japan, South Korea, and Taiwan.",

We use two datasets for Thai sentence segmentation, and the third dataset is used for English punctuation restoration. The statistics of the preprocessed data are shown in Table TABREF31 , including the number of sequences and the number of vocabulary words in each dataset. We also calculate the average number of words per passage in the unlabeled data that do not appear in the labeled data, as shown in Table TABREF32 .\nThis dataset is a Thai part-of-speech-tagged dataset containing 10,864 sentences. In the corpus, text was separated into paragraphs, sentences, and words hierarchically by linguists. Each word was also manually assigned a POS by linguists. These data include no unlabeled data with the same word segmentation and POS tag set. Hence, we do not execute CVT on this dataset.\nOur data preprocessing on the ORCHID corpus was similar to that in BIBREF8 : all the comments are removed, and the data are partitioned into 10 parts containing equal numbers of sentences to support 10-fold cross-validation. Each training set is split into one part used for validation and the rest is used for model training. Subsequently, all the words in each dataset are concatenated and then separated into sequences with 200 words per instance. Each sequence always begins with the first word of a sentence. If a sequence ends with an unfinished sentence, the next sequence starts with that complete sentence.\nThis Thai dataset includes many types of labeled data useful in sentence segmentation tasks. The raw text was generated by users having conversations in the financial domain and were acquired mainly by crawling social sites. The labeled data for sentence segmentation were manually annotated by linguists using the definitions in BIBREF21 .\nAt the time of this study, the dataset was extended from that in BIBREF21 ; the data were collected from January 2017 to December 2017. The labeled dataset includes 48,374 passages. To support semi-supervised learning, the first 3 months of data (96,777 passages) are unlabeled.\nBecause the data stem from social media, some text exists that cannot be considered as part of any sentence, such as product links, symbols unrelated to sentences, and space between sentences. These portions were not originally annotated as sentences by the linguists. However, in this work, we treat these portions as individual sentences and tag the first word of each fraction as the sentence boundary.\nFor evaluation purposes, the collection of passages in this dataset is based on 5-fold cross-validation, similar to the previous work BIBREF21 . The passages are treated as input sequences for the model. For each passage, word segmentation and POS tagging are processed by the custom models from this dataset.\nWe adopted this English-language dataset to enable comparisons with models intended for other languages. The dataset is composed of TED talk transcripts. To compare our model with those of previous works, we selected the training dataset for the machine translation track in IWSLT2012 and separated it into training and validation sets containing 2.1 million and 295 thousand words, respectively. The testing dataset is the IWSLT2011 reference set, which contains 13 thousand words. To acquire unlabeled data for semi-supervised learning, we adopted the IWSLT2016 machine translation track training data; duplicate talks that also appear in IWSLT2012 are discarded.\nThe data preprocessing follows the process in BIBREF36 . Each sequence is generated from 200 words, of which beginning is always the first word in a sentence. If a sentence is cut at the end of a sequence, that sentence is copied in full to the beginning of the next sequence.\nTo use our model, the POS of each word is required. However, the IWSLT dataset contains only the raw text of transcripts and does not include POS tags. Thus, we implement POS tagging using a special library BIBREF38 to predict the POS of each word.\nThree datasets are used in the experiments as described in the following subsections. We use two datasets for Thai sentence segmentation, and the third dataset is used for English punctuation restoration.",

The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.\n\nA laser differs from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of light with a broad spectrum but durations as short as a femtosecond.\n\nLasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, and free-space optical communication, semiconducting chip manufacturing (photolithography), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. Semiconductor lasers in the blue to near-UV have also been used in place of light-emitting diodes (LEDs) to excite fluorescence as a white light source. This permits a much smaller emitting area due to the much greater radiance of a laser and avoids the droop suffered by LEDs; such devices are already used in some car headlamps.",

        "evidence": "",
        "answer": "One of the ethical issues associated with the technique of suppression is the further underrepresentation of historically underrepresented groups. For example, within the MOOC dataset there exists only one row affiliated with a user from Antartica (continent). Similarly, the following countries have also appeared once or twice only in the entire dataset: San Marino, Falkland Islands, and Brunei. Geographically underrepresented, these pieces of information would get entirely eliminated under the suppression technique. This presents an ethical paradox: on one hand, we wish to preserve k-anonymity and protect the privacy of users from underrepresented regions; on the other hand, to reach that goal we would have to erase their existence in the dataset and further reinforce the pre-existing underrepresentation. Another example would be the column of the year of birth. The MOOCs user population are overrepresented by young people, whereas users over 80 years old only take a proportion less than 1% in the entire dataset. In particular, if we were to use the suppression technique to achieve k-anonymity, almost every piece of information associated with users over 80 years old would have to be discarded. Again, the elderly have been historically underrepresented in the industry of education, yet by using suppression, we protect their privacy at the expense of representation.\n\nThis loss of representation as a result of suppression is detrimental at multiple aspects and therefore deserves attention. As the MOOCs platform is deprived of relevant information on these users, the company will lose sight of the potential demand that these underrepresented groups have for online education, thereby failing to reach them through marketing and advertisement. Besides straining the platform’s user base and profitability, this would worsen the situation that the underrepresented groups have limited resources to online education. Moreover, inferences on the suppressed dataset could reinforce the societal bias that certain groups of people are not open to education – such as the elderly – whereas the reality is simply that we erase the information on the elderly who actively engage in online education platforms. As a result, the elderly could feel themselves further distanced from the mainstream media and technology. Therefore, using suppression alone to achieve k-anonymity within a dataset, while effective, could be complicated by the ethical issue of underrepresentation.",

        "evidence": "We evaluate the performance of text simplification using neural machine translation on available parallel sentences and additional simplified sentences.\nDataset. We use two simplification datasets (WikiSmall and WikiLarge). WikiSmall consists of ordinary and simplified sentences from the ordinary and simple English Wikipedias, which has been used as benchmark for evaluating text simplification BIBREF17 , BIBREF18 , BIBREF8 . The training set has 89,042 sentence pairs, and the test set has 100 pairs. WikiLarge is also from Wikipedia corpus whose training set contains 296,402 sentence pairs BIBREF19 , BIBREF20 . WikiLarge includes 8 (reference) simplifications for 2,359 sentences split into 2,000 for development and 359 for testing.\nMetrics. Three metrics in text simplification are chosen in this paper. BLEU BIBREF5 is one traditional machine translation metric to assess the degree to which translated simplifications differed from reference simplifications. FKGL measures the readability of the output BIBREF23 . A small FKGL represents simpler output. SARI is a recent text-simplification metric by comparing the output against the source and reference simplifications BIBREF20 .\nWe evaluate the output of all systems using human evaluation. The metric is denoted as Simplicity BIBREF8 . The three non-native fluent English speakers are shown reference sentences and output sentences. They are asked whether the output sentence is much simpler (+2), somewhat simpler (+1), equally (0), somewhat more difficult (-1), and much more difficult (-2) than the reference sentence.\nMethods. We use OpenNMT BIBREF24 as the implementation of the NMT system for all experiments BIBREF5 . We generally follow the default settings and training procedure described by Klein et al.(2017). We replace out-of-vocabulary words with a special UNK symbol. At prediction time, we replace UNK words with the highest probability score from the attention layer. OpenNMT system used on parallel data is the baseline system. To obtain a synthetic parallel training set, we back-translate a random sample of 100K sentences from the collected simplified corpora. OpenNMT used on parallel data and synthetic data is our model. The benchmarks are run on a Intel(R) Core(TM) i7-5930K CPU@3.50GHz, 32GB Mem, trained on 1 GPU GeForce GTX 1080 (Pascal) with CUDA v. 8.0.\nWe choose three statistical text simplification systems. PBMT-R is a phrase-based method with a reranking post-processing step BIBREF18 . Hybrid performs sentence splitting and deletion operations based on discourse representation structures, and then simplifies sentences with PBMT-R BIBREF25 . SBMT-SARI BIBREF19 is syntax-based translation model using PPDB paraphrase database BIBREF26 and modifies tuning function (using SARI). We choose two neural text simplification systems. NMT is a basic attention-based encoder-decoder model which uses OpenNMT framework to train with two LSTM layers, hidden states of size 500 and 500 hidden units, SGD optimizer, and a dropout rate of 0.3 BIBREF8 . Dress is an encoder-decoder model coupled with a deep reinforcement learning framework, and the parameters are chosen according to the original paper BIBREF20 . For the experiments with synthetic parallel data, we back-translate a random sample of 60 000 sentences from the collected simplified sentences into ordinary sentences. Our model is trained on synthetic data and the available parallel data, denoted as NMT+synthetic.\nResults. Table 1 shows the results of all models on WikiLarge dataset. We can see that our method (NMT+synthetic) can obtain higher BLEU, lower FKGL and high SARI compared with other models, except Dress on FKGL and SBMT-SARI on SARI. It verified that including synthetic data during training is very effective, and yields an improvement over our baseline NMF by 2.11 BLEU, 1.7 FKGL and 1.07 SARI. We also substantially outperform Dress, who previously reported SOTA result. The results of our human evaluation using Simplicity are also presented in Table 1. NMT on synthetic data is significantly better than PBMT-R, Dress, and SBMT-SARI on Simplicity. It indicates that our method with simplified data is effective at creating simpler output.\nResults on WikiSmall dataset are shown in Table 2. We see substantial improvements (6.37 BLEU) than NMT from adding simplified training data with synthetic ordinary sentences. Compared with statistical machine translation models (PBMT-R, Hybrid, SBMT-SARI), our method (NMT+synthetic) still have better results, but slightly worse FKGL and SARI. Similar to the results in WikiLarge, the results of our human evaluation using Simplicity outperforms the other models. In conclusion, Our method produces better results comparing with the baselines, which demonstrates the effectiveness of adding simplified training data.\nIt verified that including synthetic data during training is very effective, and yields an improvement over our baseline NMF by 2.11 BLEU, 1.7 FKGL and 1.07 SARI.",

        "answer": "The approach produces superior results at detecting non-factual accounts.",
        "evidence": "Social media platforms have made the spreading of fake news easier, faster as well as able to reach a wider audience. Social media offer another feature which is the anonymity for the authors, and this opens the door to many suspicious individuals or organizations to utilize these platforms. Recently, there has been an increased number of spreading fake news and rumors over the web and social media BIBREF0. Fake news in social media vary considering the intention to mislead. Some of these news are spread with the intention to be ironic or to deliver the news in an ironic way (satirical news). Others, such as propaganda, hoaxes, and clickbaits, are spread to mislead the audience or to manipulate their opinions. In the case of Twitter, suspicious news annotations should be done on a tweet rather than an account level, since some accounts mix fake with real news. However, these annotations are extremely costly and time consuming – i.e., due to high volume of available tweets Consequently, a first step in this direction, e.g., as a pre-filtering step, can be viewed as the task of detecting fake news at the account level.\nThe main obstacle for detecting suspicious Twitter accounts is due to the behavior of mixing some real news with the misleading ones. Consequently, we investigate ways to detect suspicious accounts by considering their tweets in groups (chunks). Our hypothesis is that suspicious accounts have a unique pattern in posting tweet sequences. Since their intention is to mislead, the way they transition from one set of tweets to the next has a hidden signature, biased by their intentions. Therefore, reading these tweets in chunks has the potential to improve the detection of the fake news accounts.\nIn this work, we investigate the problem of discriminating between factual and non-factual accounts in Twitter. To this end, we collect a large dataset of tweets using a list of propaganda, hoax and clickbait accounts and compare different versions of sequential chunk-based approaches using a variety of feature sets against several baselines. Several approaches have been proposed for news verification, whether in social media (rumors detection) BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, or in news claims BIBREF5, BIBREF6, BIBREF7, BIBREF8. The main orientation in the previous works is to verify the textual claims/tweets but not their sources. To the best of our knowledge, this is the first work aiming to detect factuality at the account level, and especially from a textual perspective. Our contributions are:\n[leftmargin=4mm]\nWe propose an approach to detect non-factual Twitter accounts by treating post streams as a sequence of tweets' chunks. We test several semantic and dictionary-based features together with a neural sequential approach, and apply an ablation test to investigate their contribution.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually. The results show that our approach produces superior results at detecting non-factual accounts.\nWe benchmark our approach against other approaches that discard the chronological order of the tweets or read the tweets individually.

The LMs are pre-trained on large amounts of unlabeled text which allows the NER model to use the syntactic and semantic information captured by the LM embeddings.

        "answer": "In the previous review, the reviewer pointed out a phenomenon that the improvement is not significant compared to \"Random\" and our two variants. We analyzed the phenomena and added more experiments in Appendix 3.2 to further demonstrate the effectiveness of the proposed method in practice. We thank the reviewer for the insightful comments, such that we can make our paper more well-qualified.The reviewer still believes that our ablation studies are unsupportive. To take the reviewer's concern, we summarized our major and minor contributions as follows.The two main contributions of our paper are 1) proposing criteria of data augmentations for time series based on information theory that good augmentations should have high variety and fidelity 2) proposing a meta-network to adaptively select augmentations for each dataset based on the proposed criteria. For the first contribution, we have verified with Figure 3 in Section 3 and Figure 9 in Appendix 3.2. For the second contribution, we have verified with Table 3 and Table 8 that we outperform over \"Random,\" which is used in previous works. The margins become more significant if there is no prior knowledge on the selection of augmentations (Appendix 3.2). This phenomenon shows that InfoTS is more practical because the quality of augmentations on time series data is not easy to check by humans virtually. Besides,  The comparison of InfoTS to its variants also demonstrated that both fidelity and variety are important for the selection of augmentations.  Another minor contribution in this paper is the contrastive loss. We have also verified its effectiveness with ablation studies. Thus, we believe that we have adequately verified our claims with extensive experiments. As we analyzed in the experimental part, experimental results also support our claims and we respectfully disagree with the reviewer's comment on \"unsupportive ablation study\".",
        "evidence": "Time series data in the real world is high dimensional, unstructured, and complex with unique properties, leading to challenges for data modeling. In addition, without human recognizable patterns, it is much harder to label time series data than images and languages in realworld applications. These labeling limitations hinder deep learning methods, which typically require a huge amount of labeled data for training, been applied on time series data. Representation learning learns a fixed-dimension embedding from the original time series that keeps their inherent features. Comparing to the raw time series data, these representations are with better transferability and generalization capacity. To deal with labeling limitations, contrastive learning methods have been widely adopted in various domains for their soaring performance on representation learning, including vision, language, and graph-structured data. In a nutshell, contrastive learning methods typically train an encoder to map instances to an embedding space where dissimilar (negative) instances are easily distinguishable from similar (positive) ones and model predictions to be invariant to small noise applied to either input examples or hidden states.\nDespite being effective and prevalent, contrastive learning has been less explored in the time series domain. Existing contrastive learning approaches often involve a specific data augmentation strategy that creates novel and realistic-looking training data without changing its label to construct positive alternatives for any input sample. Their success relies on carefully designed rules of thumb guided by domain expertise. Routinely used data augmentations for contrastive learning are mainly designed for image and language data, such as color distortion, flip, word replacement, and back-translation. These augmentation techniques generally do not apply to time series data.\nFigure: InfoTS is composed of three parts: (1) candidate transformation that generates different augmentations of the original inputs, (2) a meta-network that selects the optimal augmentations, (3) an encoder that learns representations of time series instances. The meta-network is learned in tandem with contrastive encoder learning.\nRecently, some researchers propose augmentations for time series to enhance the size and quality of the training data. For example, and propose to adopt jittering, scaling, and permutation strategies to generate augmented instances. extracts subsequences for data augmentation. In spite of the current progress, existing methods have two main limitations. First, unlike images with human recognizable features, time series data are often associated with inexplicable underlying patterns. Strong augmentation such as permutation may ruin such patterns and consequently, the model will mistake the negative handcrafts for positive ones. While weak augmentation methods such as jittering may generate augmented instances that are too similar to the raw inputs to be informative enough for contrastive learning. On the other hand, time series datasets from different domains may have diverse nature. Adapting a universal data augmentation method, such as subsequence in, for all datasets and tasks leads to sub-optimal performances. Other works follow empirical rules to select suitable augmentations from expensive trial-and-error. Akin to hand-crafting features, hand-picking choices of data augmentations are undesirable from the learning perspective. The diversity and heterogeneity of real-life time series data further hinder these methods away from wide applicability.\nTo address the challenges, we first introduce the criteria for selecting good data augmentations in contrastive learning. Data augmentation benefits generalizable, transferable, and robust representation learning by correctly extrapolating the input training space to a larger region. The positive instances enclose a discriminative zone in which all the data points should be similar to the original instance. The desired data augmentations for contrastive representation learning should have both high fidelity and high variety. High fidelity encourages the augmented data to maintain the semantic identity that is invariant to transformations. For example, if the downstream task is classification, then the generated augmentations of inputs should be class-preserving. Meanwhile, generating augmented samples with high variety benefits representation learning by increasing the generalization capacity. From the motivation, we theoretically analyze the information flows in data augmentations based upon information theory and derive the criteria for selecting desired time series augmentations. Due to the inexplicability in practical time series data, we assume that the semantic identity is presented by the target in the downstream task. Thus, high fidelity can be achieved by maximizing the mutual information between the downstream label and the augmented data. A one-hot pseudo label is assigned to each instance in the unsupervised setting when downstream labels are unavailable. These pseudo labels encourage augmentations of different instances to be distinguishable from each other. We show that data augmentations preserving these pseudo labels can add new information without decreasing the fidelity. Concurrently, we maximize the entropy of augmented data conditional on the original instances to increase the variety of data augmentations.\nBased on the derived criteria, we propose an adaptive data augmentation method, InfoTS (as shown in Figure), by employing a meta-learning mechanism to avoid ad-hoc choices or painstakingly trial-and-error tuning. Specifically, we utilize a meta-network to learn the augmentation prior in tandem with contrastive learning. The meta-learner automatically selects optimal augmentations from candidate augmentations to generate feasible positive samples. Along with random sampled negative instances, augmented instances are then fed into a time series encoder to learn representations in a contrastive manner. With a reparameterization trick, the meta-network can be efficiently optimized with back-propagation based upon the proposed criteria. Therefore, the meta-network can automatically select data augmentations in a per dataset and per learning task manner without resorting to expert knowledge or tedious downstream validation. Our main contributions include:\n• We propose criteria to guide the selection of data augmentations for contrastive time series representation learning without prefabricated knowledge. • We propose a meta-learning based method to automatically select feasible data augmentations for different time series datasets, which can be efficiently optimized with backpropagation. • We empirically verify the effectiveness of the proposed criteria to find optimal data augmentations. Extensive experiments demonstrate that InfoTS can achieve highly competitive performance with up to 11.4% reduction in MSE on forecasting task and up to 2.8% relative improvement in accuracy on classification task over the leading baselines.\nWe propose criteria to guide the selection of data augmentations for contrastive time series\nrepresentation learning without prefabricated knowledge. We propose a meta-learning based method to automatically select feasible data augmentations for different time series datasets, which can be efficiently optimized with backpropagation.**** In Figure 9, we show the relationship between forecasting performance and our proposed criteria. The results are consistent with the conclusion drawn from classification results that forecasting performance, evaluated with both MSE and MAE, is positively related to the proposed criteria. With the proposed criteria, we empirically show the advantage of the developed meta-network on learning optimal augmentations. The overall observations are consistent with ones from Section 4.4. Here, we provide more details. 1) “Random” is a variant that randomly selects a candidate augmentation method to generate augmented instances. “All” combines all candidate augmentations evenly to generate augmented instances. These two variances are routinely utilized in previous works (Chen et al., 2020; You et al., 2020). They work well when candidate augmentations are manually verified. Otherwise, their performances are heavily affected by the low-quality candidate augmentations, as shown in Tabel 8. On the other hand, by adaptively selecting optimal augmentations, InfoTS significantly improve the forecasting performances even with low-quality candidate augmentations. 2) By comparing InfoTS to its variant w/o Fidelity and w/o Variety, we further empirically demonstrate that both variety and fidelity make contributions to the superior performances of InfoTS.",

Once again, AI had achieved success.\n\nThe rise of expert systems\nAn expert system is a program that answers questions or solves problems about a specific domain of knowledge, using logical rules that are derived from the knowledge of experts. The earliest examples were developed by Edward Feigenbaum and his students. Dendral, begun in 1965, identified compounds from spectrometer readings. MYCIN, developed in 1972, diagnosed infectious blood diseases. They demonstrated the feasibility of the approach.\n\nExpert systems restricted themselves to a small domain of specific knowledge (thus avoiding the commonsense knowledge problem) and their simple design made it relatively easy for programs to be built and then modified once they were in place.

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nNeural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French (Bahdanau et al., 2014; Vaswani et al., 2017) and Chinese-English (Hassan et al., 2018).",

        "answer": "No.",
        "evidence": "Since the CoNLL annotations have 21 semantic roles in total, we use 21 roles in our model as well as the baseline. Following garg2012unsupervised, we set the number of PRs to 2 (excluding INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ), and SRs to 21-2=19. Table TABREF27 shows the results.\nIn the first setting (Line 1), we train and test the monolingual model on the CoNLL data. We observe significant improvements in F1 score over the Baseline (Line 0) in both languages. Using the CoNLL 2009 dataset alone, titovcrosslingual report an F1 score of 80.9% (PU=86.8%, CO=75.7%) for German. Thus, our monolingual model outperforms their monolingual model in German. For English, they report an F1 score of 83.6% (PU=87.5%, CO=80.1%), but note that our English results are not directly comparable to theirs due to differences argument identification, as discussed in section SECREF25 . As their argument identification score is lower, perhaps their system is discarding “difficult” arguments which leads to a higher clustering score.\nIn the second setting (Line 2), we use the additional monolingual Europarl (EP) data for training. We get equivalent results in English and a significant improvement in German compared to our previous setting (Line 1). The German dataset in CoNLL is quite small and benefits from the additional EP training data. In contrast, the English model is already quite good due to a relatively big dataset from CoNLL, and good accuracy syntactic parsers. Unfortunately, titovcrosslingual do not report results with this setting.\nThe third setting (Line 3) gives the results of our multilingual model, which adds the word alignments in the EP data. Comparing with Line 2, we get non-significant improvements in both languages. titovcrosslingual obtain an F1 score of 82.7% (PU=85.0%, CO=80.6%) for German, and 83.7% (PU=86.8%, CO=80.7%) for English. Thus, for German, our multilingual Bayesian model is able to capture the cross-lingual patterns at least as well as the external penalty term in BIBREF6 . We cannot compare the English results unfortunately due to differences in argument identification.\nWe also compared monolingual and bilingual training data using a setting that emulates the standard supervised setup of separate training and test data sets. We train only on the EP dataset and test on the CoNLL dataset. Lines 4 and 5 of Table TABREF27 give the results. The multilingual model obtains small improvements in both languages, which confirms the results from the standard unsupervised setup, comparing lines 2 to 3.\nThese results indicate that little information can be learned about semantic roles from this parallel data setup. One possible explanation for this result is that the setup itself is inadequate. Given the definition of aligned arguments, only 8% of English arguments and 17% of German arguments are aligned. This plus our experiments suggest that improving the alignment model is a necessary step to making effective use of parallel data in multilingual SRI, for example by joint modeling with SRI. We leave this exploration to future work.\nWe get equivalent results in English and a significant improvement in German compared to our previous setting (Line 1).",

        "question": "Based on what the authors predict the level of degradation of the speech of the patients?",
        "answer": "A specific clinical scale.",
        "evidence": "Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the mid-brain producing several motor and non-motor impairments in the patients BIBREF0. Motor symptoms include among others, bradykinesia, rigidity, resting tremor, micrographia, and different speech impairments. The speech impairments observed in PD patients are typically grouped as hypokinetic dysarthria, and include symptoms such as vocal folds rigidity, bradykinesia, and reduced control of muscles and limbs involved in the speech production. The effects of dysarthria in the speech of PD patients include increased acoustic noise, reduced intensity, harsh and breathy voice quality, increased voice nasality, monopitch, monoludness, speech rate disturbances, imprecise articulation of consonants BIBREF1, and involuntary introduction of pauses BIBREF2. Clinical observations in the speech of patients can be objectively and automatically measured by using computer aided methods supported in signal processing and pattern recognition with the aim to address two main aspects: (1) to support the diagnosis of the disease by classifying healthy control (HC) subjects and patients, and (2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.\nMost of the studies in the literature to classify PD from speech are based on computing hand-crafted features and using classifiers such as support vector machines (SVMs) or K-nearest neighbors (KNN). For instance, in BIBREF3, the authors computed features related to perturbations of the fundamental frequency and amplitude of the speech signal to classify utterances from 20 PD patients and 20 HC subjects, Turkish speakers. Classifiers based on KNN and SVMs were considered, and accuracies of up to 75% were reported. Later, in BIBREF4 the authors proposed a phonation analysis based on several time frequency representations to assess tremor in the speech of PD patients. The extracted features were based on energy and entropy computed from time frequency representations. Several classifiers were used, including Gaussian mixture models (GMMs) and SVMs. Accuracies of up to 77% were reported in utterances of the PC-GITA database BIBREF5, formed with utterances from 50 PD patients and 50 HC subjects, Colombian Spanish native speakers. The authors from BIBREF6 computed features to model different articulation deficits in PD such as vowel quality, coordination of laryngeal and supra-laryngeal activity, precision of consonant articulation, tongue movement, occlusion weakening, and speech timing. The authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier. Additional articulation features were proposed in BIBREF7, where the authors modeled the difficulty of PD patients to start/stop the vocal fold vibration in continuous speech. The model was based on the energy content in the transitions between unvoiced and voiced segments. The authors classified PD patients and HC speakers with speech recordings in three different languages (Spanish, German, and Czech), and reported accuracies ranging from 80% to 94% depending on the language; however, the results were optimistic, since the hyper-parameters of the classifier were optimized based on the accuracy on the test set. Another articulation model was proposed in BIBREF8. The authors considered a forced alignment strategy to segment the different phonetic units in the speech utterances. The phonemes were segmented and grouped to train different GMMs. The classification was performed based on a threshold of the difference between the posterior probabilities from the models created for HC subjects and PD patients. The model was tested with Colombian Spanish utterances from the PC-GITA database BIBREF5 and with the Czech data from BIBREF9. The authors reported accuracies of up to 81% for the Spanish data, and of up to 94% for the Czech data.\nIn addition to the hand-crafted feature extraction models, there is a growing interest in the research community to consider deep learning models in the assessment of the speech of PD patients BIBREF10, BIBREF11, BIBREF12. Deep learning methods have the potential to extract more abstract and robust features than those manually computed. These features could help to improve the accuracy of different models to classify pathological speech, such as PD BIBREF13. A deep learning based articulation model was proposed in BIBREF11 to model the difficulties of the patients to stop/start the vibration of the vocal folds. Transitions between voiced and unvoiced segments were modeled with time-frequency representations and convolutional neural networks (CNNs). The authors considered speech recordings of PD patients and HC speakers in three languages: Spanish, German, and Czech, and reported accuracies ranging from 70% to 89%, depending on the language. However, in a language independent scenario, i.e., training the CNN with utterances from one language and testing with the remaining two, the results were not satisfactory (accuracy$<60\\%$).\nThe classification of PD from speech in different languages has to be carefully conducted to avoid bias towards the linguistic content present in each language. For instance, Czech and German languages are richer than Spanish language in terms of consonant production, which may cause that it is easier to produce consonant sounds by Czech PD patients than by Spanish PD patients. Despite these language dependent issues, the results in the classification of PD in different languages could be improved using a transfer learning strategy among languages, i.e., to train a base model with utterances from one language, and then, to perform a fine-tuning of the weights with utterances from the target language BIBREF14. Similar approaches based on transfer learning have been recently considered to classify PD using handwriting BIBREF15. In the present study, we propose a methodology to classify PD via a transfer learning strategy with the aim to improve the accuracy in different languages. CNNs trained with utterances from one language are used to initialize a model to classify speech utterances from PD patients in a different language. The models are evaluated with speech utterances in Spanish, German, and Czech languages. The results suggest that the use of a transfer learning strategy improved the accuracy of the models over 8% with respect to those obtained when the model is trained only with utterance from the target language.\n(2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.",

        "evidence": "A clinician can look at a patient's electronic health record (EHR) and not only decide whether the patient has diabetes but also produce a succinct summary of the clinical evidence. Replicating this feat with computational tools has been the focus of much research in clinical informatics. There are major initiatives underway to codify clinical knowledge into formal representations, most often as deterministic rules that can be applied in a semi-automated fashion BIBREF0 . However, representing the intuitive judgments of human experts can be challenging, particularly when the formal system does not match the expert's knowledge. For example, many deterministic disease classifiers used in clinical informatics rely heavily upon administrative codes not available at time of diagnosis. Further, developing and testing such systems is time- and labor-intensive.\nWe propose instead a lightweight information theoretic framework for codifying informal human knowledge and then use it to extract interpretable latent topics from text corpora. For example, to discover patients with diabetes in a set of clinical notes, a doctor can begin by specifying disease-specific anchor terms BIBREF1 , BIBREF2 , such as “diabetes” or “insulin.” Our framework then uses these to help discover both latent topics associated with diabetes and records in which diabetes-related topics occur. The user can then add (or remove) additional anchor terms (e.g., “metformin”) to improve the quality of the learned (diabetes) topics.\nIn this workshop paper, we introduce a simple approach to anchored information theoretic topic modeling using a novel combination of Correlation Explanation (CorEx) BIBREF3 and the information bottleneck BIBREF4 . This flexible framework enables the user to leverage domain knowledge to guide exploration of a collection of documents and to impose semantics onto latent factors learned by CorEx. We present preliminary experimental results on two text corpora (including a corpus of clinical notes), showing that anchors can be used to discover topics that are more specific and relevant. What is more, we demonstrate the potential for this framework to perform weakly supervised learning in settings where labeling documents is prohibitively expensive BIBREF5 , BIBREF6 .\nWith respect to interpretable machine learning, our contributions are twofold. First, our framework provides a way for human users to share domain knowledge with a statistical learning algorithm that is both convenient for the human user and easily digestible by the machine. Second, our experimental results confirm that the introduction of simple anchor words can improve the coherence and human interpretability of topics discovered from data. Both are essential to successful and interactive collaboration between machine learning and human users.\nIn this workshop paper, we introduce a simple approach to anchored information theoretic topic modeling using a novel combination of Correlation Explanation (CorEx) and the information bottleneck.",

        "evidence": "Multiomics, multi-omics, integrative omics, \"panomics\" or \"pan-omics\" is a biological analysis approach in which the data sets are multiple \"omes\", such as the genome, proteome, transcriptome, epigenome, metabolome, and microbiome (i.e., a meta-genome and/or meta-transcriptome, depending upon how it is sequenced); in other words, the use of multiple omics technologies to study life in a concerted way. By combining these \"omes\", scientists can analyze complex biological big data to find novel associations between biological entities, pinpoint relevant biomarkers and build elaborate markers of disease and physiology. In doing so, multiomics integrates diverse omics data to find a coherently matching geno-pheno-envirotype relationship or association. The OmicTools service lists more than 99 softwares related to multiomic data analysis, as well as more than 99 databases on the topic.\n\nSystems biology approaches are often based upon the use of panomic analysis data. The American Society of Clinical Oncology (ASCO) defines panomics as referring to \"the interaction of all biological functions within a cell and with other body functions, combining data collected by targeted tests ... and global assays (such as genome sequencing) with other patient-specific information.\"\n\nSingle-cell multiomics\nA branch of the field of multiomics is the analysis of multilevel single-cell data, called single-cell multiomics. This approach gives us an unprecedent resolution to look at multilevel transitions in health and disease at the single cell level. An advantage in relation to bulk analysis is to mitigate confounding factors derived from cell to cell variation, allowing the uncovering of heterogeneous tissue architectures.\n\nMethods for parallel single-cell genomic and transcriptomic analysis can be based on simultaneous amplification or physical separation of RNA and genomic DNA. They allow insights that cannot be gathered solely from transcriptomic analysis, as RNA data do not contain non-coding genomic regions and information regarding copy-number variation, for example. An extension of this methodology is the integration of single-cell transcriptomes to single-cell methylomes, combining single-cell bisulfite sequencing to single cell RNA-Seq. Other techniques to query the epigenome, as single-cell ATAC-Seq and single-cell Hi-C also exist.\n\nA different, but related, challenge is the integration of proteomic and transcriptomic data. One approach to perform such measurement is to physically separate single-cell lysates in two, processing half for RNA, and half for proteins. The protein content of lysates can be measured by proximity extension assays (PEA), for example, which use DNA-barcoded antibodies. A different approach uses a combination of heavy-metal RNA probes and protein antibodies to adapt mass cytometry for multiomic analysis.\n\nMultiomics and machine learning\nIn parallel to the advances in highthroughput biology, machine learning applications to biomedical data analysis are flourishing. The integration of multi-omics data analysis and machine learning has led to the discovery of new biomarkers. For example, one of the methods of the mixOmics project implements a method based on sparse Partial Least Squares regression for selection of features (putative biomarkers).\n\n\nhttps://en.wikipedia.org/wiki/Multiomics",

In BIBREF0 we demonstrated deep learning based automatic speech recognition (ASR) using EEG signals for a limited English vocabulary of four words and five vowels. In this paper we extend our work for a much larger English vocabulary and we use state-of-art end-to-end continuous speech recognition models to perform recognition. In our prior work we predicted isolated words and vowels.\nASR systems forms the front end or back end in many cutting edge voice activated technologies like Amazon Alexa, Apple Siri, Windows Cortana, Samsung Bixby etc. Unfortunately these systems are trained to recognize text only from acoustic features. This limits technology accessibility to people with speaking disabilities and disorders. The research work presented in this paper tries to address this issue by investigating speech recognition using only EEG signals with no acoustic input and also by combining EEG features along with traditional acoustic features to perform recognition. We believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.\nASR performance is degraded in presence of noisy speech and in real life situations most of the speech is noisy. Inspired from the unique robustness to environmental artifacts exhibited by the human auditory cortex BIBREF1 , BIBREF2 we used very noisy speech data for this work and demonstrated lower word error rate (WER) for smaller corpus using EEG features, concatenation of EEG features and acoustic features.\nIn BIBREF3 authors decode imagined speech from EEG using synthetic EEG data and connectionist temporal classification (CTC) network but in our work we use real EEG data, use EEG data recorded along with acoustics. In BIBREF4 authors perform envisioned speech recognition using random forest classifier but in our case we use end to end state of art models and perform recognition for noisy speech. In BIBREF5 authors demonstrate speech recognition using electrocorticography (ECoG) signals, which are invasive in nature but in our work we use non invasive EEG signals.\nThis work is mainly motivated by the results explained in BIBREF0 , BIBREF6 , BIBREF7 , BIBREF3 . In BIBREF6 the authors used classification approach for identifying phonological categories in imagined and silent speech but in our work we used continuous speech recognition state of art models and our models were predicting words, characters at each time step. Similarly in BIBREF7 neural network based classification approach was used for predicting phonemes.\nMajor contribution of this paper is the demonstration of end to end continuous noisy speech recognition using only EEG features and this paper further validates the concepts introduced in BIBREF0 for a much larger English corpus.\nWe believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.",

Among all variants of Rouge, Rouge-2 and Rouge-3 are better correlated with manual judgments in the context of scientific summarization.

        "evidence": "Neural machine translation has recently achieved impressive results BIBREF0 , BIBREF1 , while learning from raw, sentence-aligned parallel text and using little in the way of external linguistic information. However, we hypothesize that various levels of linguistic annotation can be valuable for neural machine translation. Lemmatisation can reduce data sparseness, and allow inflectional variants of the same word to explicitly share a representation in the model. Other types of annotation, such as parts-of-speech (POS) or syntactic dependency labels, can help in disambiguation. In this paper we investigate whether linguistic information is beneficial to neural translation models, or whether their strong learning capability makes explicit linguistic features redundant.\nLet us motivate the use of linguistic features using examples of actual translation errors by neural MT systems. In translation out of English, one problem is that the same surface word form may be shared between several word types, due to homonymy or word formation processes such as conversion. For instance, close can be a verb, adjective, or noun, and these different meanings often have distinct translations into other languages. Consider the following English INLINEFORM0 German example:\nFor the English source sentence in Example SECREF4 (our translation in Example SECREF5 ), a neural MT system (our baseline system from Section SECREF4 ) mistranslates close as a verb, and produces the German verb schließen (Example SECREF6 ), even though close is an adjective in this sentence, which has the German translation nah. Intuitively, part-of-speech annotation of the English input could disambiguate between verb, noun, and adjective meanings of close.\nAs a second example, consider the following German INLINEFORM0 English example:\nGerman main clauses have a verb-second (V2) word order, whereas English word order is generally SVO. The German sentence (Example UID7 ; English reference in Example UID8 ) topicalizes the predicate gefährlich 'dangerous', putting the subject die Route 'the route' after the verb. Our baseline system (Example UID9 ) retains the original word order, which is highly unusual in English, especially for prose in the news domain. A syntactic annotation of the source sentence could support the attentional encoder-decoder in learning which words in the German source to attend (and translate) first.\nWe will investigate the usefulness of linguistic features for the language pair German INLINEFORM0 English, considering the following linguistic features:\nThe inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form. The other linguistic features are motivated by disambiguation, as discussed in our introductory examples.\nThe neural machine translation system is implemented as an attentional encoder-decoder network with recurrent neural networks.",

In the context of images, a good adversarial example is typically defined according two criteria:\nit has successfully fooled the classifier;\nit is visually similar to the original example.\nIn NLP, defining a good adversarial example is a little more involving, because while criterion (b) can be measured with a comparable text similarity metric (e.g. BLEU or edit distance), an adversarial example should also:\nbe fluent or natural;\npreserve its original label.\nThese two additional criteria are generally irrelevant for images, as adding minor perturbations to an image is unlikely to: (1) create an uninterpretable image (where else changing one word in a sentence can render a sentence incoherent), or (2) change how we perceive the image, say from seeing a panda to a gibbon (but a sentence's sentiment can be reversed by simply adding a negative adverb such as not). Without considering criterion (d), generating adversarial examples in NLP would be trivial, as the model can learn to simply replace a positive adjective (amazing) with a negative one (awful) to attack a sentiment classifier.\nTo the best of our knowledge, most studies on adversarial example generation in NLP have largely ignored these additional criteria BIBREF2, BIBREF3, BIBREF4, BIBREF5. We believe the lack of a rigorous evaluation framework partially explains why adversarial training for NLP models has not seen the same extent of improvement compared to CV models. As our experiments reveal, examples generated from most attacking methods are successful in fooling the classifier, but their language is often unnatural and the original label is not properly preserved.\nThe core contribution of our paper is to introduce a systematic, rigorous evaluation framework to assess the quality of adversarial examples for NLP. We focus on sentiment classification as the target task, as it is a popular application that highlights the importance of criteria discussed above. We test a number of attacking methods and also propose an alternative approach (based on an auto-encoder) for generating adversarial examples. We learn that a number of factors can influence the performance of adversarial attacks, including architecture of the classifier, sentence length and input domain.\nWe test a number of attacking methods and also propose an alternative approach (based on an auto-encoder) for generating adversarial examples.",

        "question": "What first-hand accounts did this paper analyse?",
        "answer": "This paper is to analyse first-hand accounts by individuals with lived experience of severe mental health issues.",
        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nConcurrently, it has been argued for mental health research that it would constitute a ‘valuable critical step’ (Stuart et al., 2017) to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums.",

        "question": "From the following passage, which taxes/acts led to the American Revolution?",
        "evidence": "1764–1766: Taxes imposed and withdrawn\nMain articles: Sugar Act, Currency Act, Quartering Acts, Stamp Act 1765, and Declaratory Act\nFurther information: No taxation without representation and Virtual representation\n\nNotice of the Stamp Act 1765 in a colonial newspaper\nIn 1764 Parliament passed the Sugar Act, decreasing the existing customs duties on sugar and molasses but providing stricter measures of enforcement and collection. That same year, Prime Minister George Grenville proposed direct taxes on the colonies to raise revenue, but he delayed action to see whether the colonies would propose some way to raise the revenue themselves.\n\nGrenville had asserted in 1762 that the whole revenue of the custom houses in America amounted to one or two thousand pounds sterling a year, and that the English exchequer was paying between seven and eight thousand pounds a year to collect. Adam Smith wrote in The Wealth of Nations that Parliament \"has never hitherto demanded of [the American colonies] anything which even approached to a just proportion to what was paid by their fellow subjects at home.\" Benjamin Franklin would later testify in Parliament in 1766 to the contrary, reporting that Americans already contributed heavily to the defense of the Empire. He argued that local colonial governments had raised, outfitted, and paid 25,000 soldiers to fight France in just the French and Indian War alone—as many as Britain itself sent—and spent many millions from American treasuries doing so.\n\nParliament finally passed the Stamp Act in March 1765, which imposed direct taxes on the colonies for the first time. All official documents, newspapers, almanacs, and pamphlets were required to have the stamps—even decks of playing cards. The colonists did not object that the taxes were high; they were actually low. They objected to their lack of representation in the Parliament, which gave them no voice concerning legislation that affected them. The British were, however, reacting to an entirely different issue: at the conclusion of the recent war the Crown had to deal with approximately 1,500 politically well-connected British Army officers. The decision was made to keep them on active duty with full pay, but they—and their commands—also had to be stationed somewhere. Stationing a standing army in Great Britain during peacetime was politically unacceptable, so they determined to station them in America and have the Americans pay them through the new tax. The soldiers had no military mission however; they were not there to defend the colonies because there was no current threat to the colonies.\n\nThe Sons of Liberty formed shortly after the Act in 1765, and they used public demonstrations, boycotts, and threats of violence to ensure that the British tax laws were unenforceable. In Boston, the Sons of Liberty burned the records of the vice admiralty court and looted the home of chief justice Thomas Hutchinson. Several legislatures called for united action, and nine colonies sent delegates to the Stamp Act Congress in New York City in October. Moderates led by John Dickinson drew up a Declaration of Rights and Grievances stating that taxes passed without representation violated their rights as Englishmen, and colonists emphasized their determination by boycotting imports of British merchandise.\n\nThe Parliament at Westminster saw itself as the supreme lawmaking authority throughout the Empire and thus entitled to levy any tax without colonial approval or even consultation. They argued that the colonies were legally British corporations subordinate to the British Parliament, and they pointed to numerous instances where Parliament had made laws in the past that were binding on the colonies. Parliament insisted that the colonists effectively enjoyed a \"virtual representation\", as most British people did, since only a small minority of the British population elected representatives to Parliament. However, Americans such as James Otis maintained that there was no one in Parliament responsible specifically for any colonial constituency, so they were not \"virtually represented\" by anyone in Parliament at all.\n\nThe Rockingham government came to power in July 1765, and Parliament debated whether to repeal the stamp tax or to send an army to enforce it. Benjamin Franklin made the case for repeal, explaining that the colonies had spent heavily in manpower, money, and blood defending the empire in a series of wars against the French and indigenous people, and that further taxes to pay for those wars were unjust and might bring about a rebellion. Parliament agreed and repealed the tax on February 21, 1766, but they insisted in the Declaratory Act of March 1766 that they retained full power to make laws for the colonies \"in all cases whatsoever\". The repeal nonetheless caused widespread celebrations in the colonies.\n\n1767–1773: Townshend Acts and the Tea Act\nMain articles: Townshend Acts and Tea Act\nFurther information: Crisis of 1772, Massachusetts Circular Letter, Boston Massacre, and Boston Tea Party\n\nLetter III of John Dickinson's Letters from a Farmer in Pennsylvania, published in the Pennsylvania Chronicle, December 1767\nIn 1767, the Parliament passed the Townshend Acts which placed duties on a number of staple goods, including paper, glass, and tea, and established a Board of Customs in Boston to more rigorously execute trade regulations. The new taxes were enacted on the belief that Americans only objected to internal taxes and not to external taxes such as custom duties. However, in his widely read pamphlet, Letters from a Farmer in Pennsylvania, John Dickinson argued against the constitutionality of the acts because their purpose was to raise revenue and not to regulate trade. Colonists responded to the taxes by organizing new boycotts of British goods. These boycotts were less effective, however, as the goods taxed by the Townshend Acts were widely used.\n\nIn February 1768, the Assembly of Massachusetts Bay issued a circular letter to the other colonies urging them to coordinate resistance. The governor dissolved the assembly when it refused to rescind the letter. Meanwhile, a riot broke out in Boston in June 1768 over the seizure of the sloop Liberty, owned by John Hancock, for alleged smuggling. Customs officials were forced to flee, prompting the British to deploy troops to Boston. A Boston town meeting declared that no obedience was due to parliamentary laws and called for the convening of a convention. A convention assembled but only issued a mild protest before dissolving itself. In January 1769, Parliament responded to the unrest by reactivating the Treason Act 1543 which called for subjects outside the realm to face trials for treason in England. The governor of Massachusetts was instructed to collect evidence of said treason, and the threat caused widespread outrage, though it was not carried out.\n\nOn March 5, 1770, a large crowd gathered around a group of British soldiers on a Boston street. The crowd grew threatening, throwing snowballs, rocks, and debris at them. One soldier was clubbed and fell. There was no order to fire, but the soldiers panicked and fired into the crowd. They hit 11 people; three civilians died of wounds at the scene of the shooting, and two died shortly after the incident. The event quickly came to be called the Boston Massacre. The soldiers were tried and acquitted (defended by John Adams), but the widespread descriptions soon began to turn colonial sentiment against the British. This accelerated the downward spiral in the relationship between Britain and the Province of Massachusetts.\n\nA new ministry under Lord North came to power in 1770, and Parliament withdrew all taxes except the tax on tea, giving up its efforts to raise revenue while maintaining the right to tax. This temporarily resolved the crisis, and the boycott of British goods largely ceased, with only the more radical patriots such as Samuel Adams continuing to agitate.[citation needed]\n\n\nOn June 9, 1772, the Sons of Liberty burned HMS Gaspee, a British customs schooner in Narragansett Bay.\nIn June 1772, American patriots, including John Brown, burned a British warship that had been vigorously enforcing unpopular trade regulations, in what became known as the Gaspee Affair. The affair was investigated for possible treason, but no action was taken.\n\nIn 1772, it became known that the Crown intended to pay fixed salaries to the governors and judges in Massachusetts, which had been paid by local authorities. This would reduce the influence of colonial representatives over their government. Samuel Adams in Boston set about creating new Committees of Correspondence, which linked Patriots in all 13 colonies and eventually provided the framework for a rebel government. Virginia, the largest colony, set up its Committee of Correspondence in early 1773, on which Patrick Henry and Thomas Jefferson served.\n\nA total of about 7,000 to 8,000 Patriots served on Committees of Correspondence at the colonial and local levels, comprising most of the leadership in their communities. Loyalists were excluded. The committees became the leaders of the American resistance to British actions, and later largely determined the war effort at the state and local level. When the First Continental Congress decided to boycott British products, the colonial and local Committees took charge, examining merchant records and publishing the names of merchants who attempted to defy the boycott by importing British goods.\n\nIn 1773, private letters were published in which Massachusetts Governor Thomas Hutchinson claimed that the colonists could not enjoy all English liberties, and in which Lieutenant Governor Andrew Oliver called for the direct payment of colonial officials. The letters' contents were used as evidence of a systematic plot against American rights, and discredited Hutchinson in the eyes of the people; the colonial Assembly petitioned for his recall. Benjamin Franklin, postmaster general for the colonies, acknowledged that he leaked the letters, which led to him being berated by British officials and removed from his position.\n\n\nThe December 16, 1773 Boston Tea Party, led by Samuel Adams and Sons of Liberty, has become a mainstay of American patriotic lore.\nMeanwhile, Parliament passed the Tea Act lowering the price of taxed tea exported to the colonies, to help the British East India Company undersell smuggled untaxed Dutch tea. Special consignees were appointed to sell the tea to bypass colonial merchants. The act was opposed by those who resisted the taxes and also by smugglers who stood to lose business.[citation needed] In most instances, the consignees were forced by the Americans to resign and the tea was turned back, but Massachusetts governor Hutchinson refused to allow Boston merchants to give in to pressure. A town meeting in Boston determined that the tea would not be landed, and ignored a demand from the governor to disperse. On December 16, 1773, a group of men, led by Samuel Adams and dressed to evoke the appearance of indigenous people, boarded the ships of the East India Company and dumped £10,000 worth of tea from their holds (approximately £636,000 in 2008) into Boston Harbor. Decades later, this event became known as the Boston Tea Party and remains a significant part of American patriotic lore.\n\n1774–1775: Intolerable Acts\nMain article: Intolerable Acts\nFurther information: Quebec Act and Continental Association\n\nA 1774 etching from The London Magazine depicts Prime Minister Lord North, author of the Boston Port Act, forcing the Intolerable Acts down the throat of America, whose arms are restrained by Lord Chief Justice Mansfield, and a tattered \"Boston Petition\" lays trampled on the ground beside her. Lord Sandwich pins down her feet and peers up her robes; behind them, Mother Britannia weeps while France and Spain look on.\nThe British government responded by passing several measures that came to be known as the Intolerable Acts, further darkening colonial opinion towards England. They consisted of four laws enacted by the British parliament. The first was the Massachusetts Government Act which altered the Massachusetts charter and restricted town meetings. The second act was the Administration of Justice Act which ordered that all British soldiers to be tried were to be arraigned in Britain, not in the colonies. The third Act was the Boston Port Act, which closed the port of Boston until the British had been compensated for the tea lost in the Boston Tea Party. The fourth Act was the Quartering Act of 1774, which allowed royal governors to house British troops in the homes of citizens without requiring permission of the owner.\n\nIn response, Massachusetts patriots issued the Suffolk Resolves and formed an alternative shadow government known as the Provincial Congress which began training militia outside British-occupied Boston. In September 1774, the First Continental Congress convened, consisting of representatives from each colony, to serve as a vehicle for deliberation and collective action. During secret debates, conservative Joseph Galloway proposed the creation of a colonial Parliament that would be able to approve or disapprove acts of the British Parliament, but his idea was tabled in a vote of 6 to 5 and was subsequently removed from the record.[citation needed] Congress called for a boycott beginning on December 1, 1774, of all British goods; it was enforced by new local committees authorized by the Congress.",

        "answer": "Automatically mapping a natural language question such as “Where was Barack Obama born? ”to its corresponding KB query remains a challenging task.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nHowever, automatically mapping a natural language question such as “Where was Barack Obama born? ”to its corresponding KB query remains a challenging task.",

The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.",

        "evidence": "Results for IV evaluation are shown in tab:intrinsic, and for OOV in tab:oov.\nLike in FT, the use of subword information in both LV-N and LV-M results in 1) better representation of rare words, as evidenced by the increase in RW correlation, and 2) significant improvement on the GSyn and MSR tasks, in evidence of subwords encoding information about a word's syntactic function (the suffix “ly”, for example, suggests an adverb).\nThere seems to a trade-off between capturing semantics and syntax as in both LV-N and FT there is an accompanying decrease on the GSem tasks in exchange for gains on the GSyn and MSR tasks. Morphological segmentation in LV-M appears to favor syntax less strongly than do simple n-grams.\nOn the downstream tasks, we only observe statistically significant ( $p < .05$ under a random permutation test) improvement on the chunking task, and it is a very small gain. We attribute this to both regular and subword models having very similar quality on frequent IV word representation. Statistically, these are the words are that are most likely to appear in the downstream task instances, and so the superior representation of rare words\nhas, due to their nature, little impact on overall accuracy. Because in all tasks OOV words are mapped to the “ $\\langle $ unk $\\rangle $ ” token, the subword models are not being used to the fullest, and in future work we will investigate whether generating representations for all words improves task performance.\nIn OOV representation (tab:oov), LV-N and FT work almost identically, as is to be expected. Both find highly coherent neighbors for the words “hellooo”, “marvelicious”, and “rereread”. Interestingly, the misspelling of “louisana” leads to coherent name-like neighbors, although none is the expected correct spelling “louisiana”. All models stumble on the made-up prefix “tuz”. A possible fix would be to down-weigh very rare subwords in the vector summation. LV-M is less robust than LV-N and FT on this task as it is highly sensitive to incorrect segmentation, exemplified in the “hellooo” example.\nFinally, we see that nearest-neighbors are a mixture of similarly pre/suffixed words. If these pre/suffixes are semantic, the neighbors are semantically related, else if syntactic they have similar syntactic function. This suggests that it should be possible to get tunable representations which are more driven by semantics or syntax by a weighted summation of subword vectors, given we can identify whether a pre/suffix is semantic or syntactic in nature and weigh them accordingly. This might be possible without supervision using corpus statistics as syntactic subwords are likely to be more frequent, and so could be down-weighted for more semantic representations. This is something we will pursue in future work.\nIn OOV representation (table 2), LV-N and FT work almost identically, as is to be expected.",

        "evidence": "Automated deriving discourse relation from free text is a challenging but im-portant problem. The shallow discourse parsing is very useful in the text summariza-tion BIBREF0 , opinion analysis BIBREF1 and natural language generation. Shallow discourse parser is the system of parsing raw text into a set of discourse relations between two adjacent or non-adjacent text spans. Discourse relation is composed of a discourse connective, two arguments of the discourse connective and the sense of the discourse connective. Discourse connective signals the explicit dis-course relation, but in non-explicit discourse relation, a discourse connective is omit-ted. Two arguments of the discourse connective, Arg1 and Arg2, which are the two adjacent or non-adjacent text spans connecting in the discourse relation. The sense of the discourse connective characterizes the nature of the discourse relations. The following discourse relation annotation is taken from the document in the PDTB. Arg1 is shown in italicized, and Arg2 is shown in bold. The discourse connective is underlined.\nThe connective identifier finds the connective word, “unless”. The arguments identifier locates the two arguments of “unless”. The sense classifier labels the dis-course relation. The non-explicit identifier checks all the pair of adjacent sentences. If the non-explicit identifier indentifies the pair of sentences as non-explicit relation, it will label it the relation sense. Though many research work BIBREF2 , BIBREF3 , BIBREF4 are committed to the shallow discourse parsing field, all of them are focus on the subtask of parsing only rather than the whole parsing process. Given all that, a full shallow discourse parser framework is proposed in our paper to turn the free text into discourse relations set. The parser includes connective identifier, arguments identifier, sense classifier and non-explicit identifier, which connects with each other in pipeline. In order to enhance the performance of the parser, the feature-based maximum entropy model approach is adopted in the experiment. Maximum entropy model offers a clean way to combine diverse pieces of contextual evidence in order to estimate the probability of a certain linguistic class occurring with a certain linguistic context in a simple and accessible manner. The three main contributions of the paper are:\nThe rest of this paper is organized as follows. Section 2 reviews related work in discourse parsing. Section 3 describes the experimental corpus–PDTB. Section 4 de-scribes the framework and the components of the parser. Section 5 presents experi-ments and evaluations.

According to Frank,\nIf we deconstruct that these foods were inherently native, then that means that the Italians didn't have the tomato, the Irish didn't have the potato, half the British National Dish—Fish and Chips—didn't exist. The Russians didn't have the potato, nor did they have vodka from the potato.

And the French had no confection using either vanilla or chocolate. So the Old World was a completely different place.",

Between FGM and FGVM, the former introduce noises that is proportional to the sign of the gradients while the latter introduce perturbations proportional to the gradients directly. The proportion is known as the overshoot value and denoted by $\\epsilon $. DeepFool uses the same trick to deal with discrete inputs except that, instead of using the fast gradient method, it uses the DeepFool method introduced in BIBREF8 for image to search for an optimal direction to perturb the word embeddings.\nUnlike the previous methods, HotFlip and TYC rely on performing one or more atomic flip operations to replace words while monitoring the label change given by the target classifier. In HotFlip, the directional derivatives w.r.t. flip operations are calculated and the flip operation that results in the largest increase in loss is selected. TYC is similar to FGM, FGVM and DeepFool in that it also uses nearest neighbour search to map the perturbed embeddings to valid words, but instead of using the perturbed tokens directly, it uses greedy search or beam search to flip original tokens to perturbed ones one at a time in order of their vulnerability.\nWe experiment with six benchmark attacking methods for texts, ranging from white-box attacks: FGM, FGVM, DEEPFOOL (Gong et al., 2018), HOTFLIP (Ebrahimi et al., 2017)), and TYC (Tsai et al., 2019) to black-box attacks: TEXTFOOLER (Jin et al., 2019).",

        "question": "Do the resultant binary paragraph vectors significantly outperform semantic hashing codes?",
        "answer": "Yes, they do.",
        "evidence": "One of the significant challenges in contemporary information processing is the sheer volume of available data. BIBREF0 , for example, claim that the amount of digital data in the world doubles every two years. This trend underpins efforts to develop algorithms that can efficiently search for relevant information in huge datasets. One class of such algorithms, represented by, e.g., Locality Sensitive Hashing BIBREF1 , relies on hashing data into short, locality-preserving binary codes BIBREF2 . The codes can then be used to group the data into buckets, thereby enabling sublinear search for relevant information, or for fast comparison of data items. Most of the algorithms from this family are data-oblivious, i.e. can generate hashes for any type of data. Nevertheless, some methods target specific kind of input data, like text or image.\nIn this work we focus on learning binary codes for text documents. An important work in this direction has been presented by BIBREF3 . Their semantic hashing leverages autoencoders with sigmoid bottleneck layer to learn binary codes from a word-count bag-of-words (BOW) representation. Salakhutdinov & Hinton report that binary codes allow for up to 20-fold improvement in document ranking speed, compared to real-valued representation of the same dimensionality. Moreover, they demonstrate that semantic hashing codes used as an initial document filter can improve precision of TF-IDF-based retrieval. Learning binary representation from BOW, however, has its disadvantages. First, word-count representation, and in turn the learned codes, are not in itself stronger than TF-IDF. Second, BOW is an inefficient representation: even for moderate-size vocabularies BOW vectors can have thousands of dimensions. Learning fully-connected autoencoders for such high-dimensional vectors is impractical. Salakhutdinov & Hinton restricted the BOW vocabulary in their experiments to 2000 most frequent words.\nBinary codes have also been applied to cross-modal retrieval where text is one of the modalities. Specifically, BIBREF4 incorporated tag information that often accompany text documents, while BIBREF5 employed siamese neural networks to learn single binary representation for text and image data.\nRecently several works explored simple neural models for unsupervised learning of distributed representations of words, sentences and documents. BIBREF6 proposed log-linear models that learn distributed representations of words by predicting a central word from its context (CBOW model) or by predicting context words given the central word (Skip-gram model). The CBOW model was then extended by BIBREF7 to learn distributed representations of documents. Specifically, they proposed Paragraph Vector Distributed Memory (PV-DM) model, in which the central word is predicted given the context words and the document vector. During training, PV-DM learns the word embeddings and the parameters of the softmax that models the conditional probability distribution for the central words. During inference, word embeddings and softmax weights are fixed, but the gradients are backpropagated to the inferred document vector. In addition to PV-DM, Le & Mikolov studied also a simpler model, namely Paragraph Vector Distributed Bag of Words (PV-DBOW). This model predicts words in the document given only the document vector. It therefore disregards context surrounding the predicted word and does not learn word embeddings. Le & Mikolov demonstrated that paragraph vectors outperform BOW and bag-of-bigrams in information retrieval task, while using only few hundreds of dimensions. These models are also amendable to learning and inference over large vocabularies. Original CBOW network used hierarchical softmax to model the probability distribution for the central word. One can also use noise-contrastive estimation BIBREF8 or importance sampling BIBREF9 to approximate the gradients with respect to the softmax logits.\nAn alternative approach to learning representation of pieces of text has been recently described by BIBREF10 . Networks proposed therein, inspired by the Skip-gram model, learn to predict surrounding sentences given the center sentence. To this end, the center sentence is encoded by an encoder network and the surrounding sentences are predicted by a decoder network conditioned on the center sentence code. Once trained, these models can encode sentences without resorting to backpropagation inference. However, they learn representations at the sentence level but not at the document level.\nIn this work we present Binary Paragraph Vector models, an extensions to PV-DBOW and PV-DM that learn short binary codes for text documents. One inspiration for binary paragraph vectors comes from a recent work by BIBREF11 on learning binary codes for images. Specifically, we introduce a sigmoid layer to the paragraph vector models, and train it in a way that encourages binary activations. We demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes. We also evaluate binary paragraph vectors in transfer learning settings, where training and inference are carried out on unrelated text corpora. Finally, we study models that simultaneously learn short binary codes for document filtering and longer, real-valued representations for ranking. While BIBREF11 employed a supervised criterion to learn image codes, binary paragraph vectors remain unsupervised models: they learn to predict words in documents.\nWe demonstrate that the resultant binary paragraph vectors significantly outperform semantic hashing codes.",

QE research has grown increasingly popular due to the improved quality of MT systems, and potential for reductions in post-editing time and the corresponding savings in labor costs BIBREF2 , BIBREF3 . QE can be performed on multiple granularities, including at word level, sentence level, or document level. In this paper, we focus on quality estimation at word level, which is framed as the task of performing binary classification of translated tokens, assigning “OK” or “BAD” labels.\nEarly work on this problem mainly focused on hand-crafted features with simple regression/classification models BIBREF4 , BIBREF5 . Recent papers have demonstrated that utilizing recurrent neural networks (RNN) can result in large gains in QE performance BIBREF6 . However, these approaches encode the context of the target word by merely concatenating its left and right context words, giving them limited ability to control the interaction between the local context and the target word.\nIn this paper, we propose a neural architecture, Context Encoding Quality Estimation (CEQE), for better encoding of context in word-level QE. Specifically, we leverage the power of both (1) convolution modules that automatically learn local patterns of surrounding words, and (2) hand-crafted features that allow the model to make more robust predictions in the face of a paucity of labeled data.

Today, applications of machine-learning techniques comprise a broad variety of research areas related to Linked Data, such as Link Discovery, Named Entity Recognition, and Structured Question Answering. The field of Knowledge Graph Embedding (KGE) has emerged in the Machine Learning community during the last five years. The underlying concept of KGE is that in a knowledge base, each entity and relation can be regarded as a vector in a continuous space. The generated vector representations can be used by algorithms employing machine learning, deep learning, or statistical relational learning to accomplish a given task. Several KGE approaches have already shown promising results on tasks such as link prediction, entity recommendation, question answering, and triplet classification BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 .

A recent emphasis on learned methods has shown a large set of CNN BIBREF29 and LSTM BIBREF8 variants achieve similar accuracy on TREC question classification, with these models exhibiting at best small gains over simple term frequency models. These recent developments echo the observations of Roberts et al. BIBREF3 , who showed that existing methods beyond term frequency models failed to generalize to medical domain questions. Here we show that strong performance across multiple datasets is possible using a single learned model.\nDue to the cost involved in their construction, question classification datasets and classification taxonomies tend to be small, which can create methodological challenges. Roberts et al. BIBREF3 generated the next-largest dataset from TREC, containing 2,936 consumer health questions classified into 13 question categories. More recently, Wasim et al. BIBREF4 generated a small corpus of 780 biomedical domain questions organized into 88 categories. In the education domain, Godea et al. BIBREF5 collected a set of 1,155 classroom questions and organized these into 16 categories.

        "evidence": "By extending the solution of sequence-to-sequence modeling using encoder-decoder architectures to multi-task learning, Luong2016 managed to achieve better performance on some INLINEFORM0 tasks such as translation, parsing and image captioning compared to individual tasks. Specifically in translation, the work utilizes multiple encoders to translate from multiple languages, and multiple decoders to translate to multiple languages. In this view of multilingual translation, each language in source or target side is modeled by one encoder or decoder, depending on the side of the translation. Due to the natural diversity between two tasks in that multi-task learning scenario, e.g. translation and parsing, it could not feature the attention mechanism although it has proven its effectiveness in NMT. There exists two directions which proposed for multilingual translation scenarios where they leverage the attention mechanism. The first one is indicated in the work from BIBREF8 , where it introduce an one-to-many multilingual NMT system to translates from one source language into multiple target languages. Having one source language, the attention mechanism is then handed over to the corresponding decoder. The objective function is changed to adapt to multilingual settings. In testing time, the parameters specific to a desired language pair are used to perform the translation.\nFirat2016 proposed another approach which genuinely delivers attention-based NMT to multilingual translation. As in BIBREF9 , their approach utilizes one encoder per source language and one decoder per target language for many-to-many translation tasks. Instead of a quadratic number of independent attention layers, however, one single attention mechanism is integrated into their NMT, performing an affine transformation between the hidden layer of INLINEFORM0 source languages and that one of INLINEFORM1 target languages. It is required to change their architecture to accomodate such a complicated shared attention mechanism.\nIn a separate effort to achieve multilingual NMT, the work of Zoph2016 leverages available parallel data from other language pairs to help reducing possible ambiguities in the translation process into a single target language. They employed the multi-source attention-based NMT in a way that only one attention mechanism is required despite having multiple encoders. To achieve this, the outputs of the encoders were combined before feeding to the attention layer. They implemented two types of encoder combination; One is adding a non-linear layer on the concatenation of the encoders' hidden states. The other is using a variant of LSTM taking the respective gate values from the individual LSTM units of the encoders. As a result, the combined hidden states contain information from both encoders , thus encode the common semantic of the two source languages.\nIn a separate effort to achieve multilingual NMT, the work of Zoph and Knight (2016) leverages available parallel data from other language pairs to help reducing possible ambiguities in the translation process into a single target language2.

        "evidence": "The Hundred Years' War (French: La guerre de Cent Ans; 1337–1453) was a series of armed conflicts between the kingdoms of England and France during the Late Middle Ages. It originated from disputed claims to the French throne between the English House of Plantagenet and the French royal House of Valois. Over time, the war grew into a broader power struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides.",
        "answer": "The English and French fought numerous battles from the mid-14th century to the mid-15th century, hence the name, \"Hundred Years War.\" The two sides made conflicting claims of sovereignty over land and people in an effort to be the dominant power in Western Europe, if not all of Europe. Engaging in warfare over this extended period of time resulted in a fairly rapid evolution of warfare and how countries conducted war. For example, standing armies for each country became a standard, a new development in the nationalism.",

        "evidence": "In this work we formulate our classification problem as follows: given two classes of news articles, respectively $D$ (disinformation) and $M$ (mainstream), a set of news articles $A_i$ and associated class labels $C_i \\in \\lbrace D,M\\rbrace $, and a set of tweets $\\Pi _i=\\lbrace T_i^1, T_i^2, ...\\rbrace $ each of which contains an Uniform Resource Locator (URL) pointing explicitly to article $A_i$, predict the class $C_i$ of each article $A_i$. There is huge debate and controversy on a proper taxonomy of malicious and deceptive information BIBREF1BIBREF2BIBREF15BIBREF16BIBREF17BIBREF3BIBREF11. In this work we prefer the term disinformation to the more specific fake news to refer to a variety of misleading and harmful information. Therefore, we follow a source-based approach, a consolidated strategy also adopted by BIBREF6BIBREF16BIBREF2BIBREF1, in order to obtain relevant data for our analysis. We collected:\nDisinformation articles, published by websites which are well-known for producing low-credibility content, false and misleading news reports as well as extreme propaganda and hoaxes and flagged as such by reputable journalists and fact-checkers;\nMainstream news, referring to traditional news outlets which deliver factual and credible information.\nWe believe that this is currently the most reliable classification approach, but it entails obvious limitations, as disinformation outlets may also publish true stories and likewise misinformation is sometimes reported on mainstream media. Also, given the choice of news sources, we cannot test whether our methodology is able to classify disinformation vs factual but not mainstream news which are published on niche, non-disinformation outlets.\nWe collected tweets associated to a dozen US mainstream news websites, i.e. most trusted sources described in BIBREF18, with the Streaming API, and we referred to Hoaxy API BIBREF16 for what concerns tweets containing links to 100+ US disinformation outlets. We filtered out articles associated to less than 50 tweets. The resulting dataset contains overall $\\sim $1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and $\\sim $1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles. Diffusion censoring effects BIBREF14 were correctly taken into account in both collection procedures. We provide in Figure FIGREF4 the distribution of articles by source and political bias for both news domains.\nAs it is reported that conservatives and liberals exhibit different behaviors on online social platforms BIBREF19BIBREF20BIBREF21, we further assigned a political bias label to different US outlets (and therefore news articles) following the procedure described in BIBREF2. In order to assess the robustness of our method, we performed classification experiments by training only on left-biased (or right-biased) outlets of both disinformation and mainstream domains and testing on the entire set of sources, as well as excluding particular sources that outweigh the others in terms of samples to avoid over-fitting.\nFor what concerns the Italian scenario we first collected tweets with the Streaming API in a 3-week period (April 19th, 2019-May 5th, 2019), filtering those containing URLs pointing to Italian official newspapers websites as described in BIBREF22; these correspond to the list provided by the association for the verification of newspaper circulation in Italy (Accertamenti Diffusione Stampa). We instead referred to the dataset provided by BIBREF23 to obtain a set of tweets, collected continuously since January 2019 using the same Twitter endpoint, which contain URLs to 60+ Italian disinformation websites. In order to get balanced classes (April 5th, 2019-May 5th, 2019), we retained data collected in a longer period w.r.t to mainstream news. In both cases we filtered out articles with less than 50 tweets; overall this dataset contains $\\sim $160k mainstream tweets, corresponding to 227 news articles, and $\\sim $100k disinformation tweets, corresponding to 237 news articles. We provide in Figure FIGREF5 the distribution of articles according to distinct sources for both news domains. As in the US dataset, we took into account censoring effects BIBREF14 by excluding tweets published before (left-censoring) or after two weeks (right-censoring) from the beginning of the collection process.\nThe different volumes of news shared on Twitter in the two countries are due both to the different population size of US and Italy (320 vs 60 millions) but also to the different usage of Twitter platform (and social media in general) for news consumption BIBREF24. Both datasets analyzed in this work are available from the authors on request.\nA crucial aspect in our approach is the capability to fully capturing sharing cascades on Twitter associated to news articles. It has been reported BIBREF25 that the Twitter streaming endpoint filters out tweets matching a given query if they exceed 1% of the global daily volume of shared tweets, which nowadays is approximately $5\\cdot 10^8$; however, as we always collected less than $10^6$ tweets per day, we did not incur in this issue and we thus gathered 100% of tweets matching our query.\nWe built Twitter diffusion networks following an approach widely adopted in the literature BIBREF6BIBREF17BIBREF2. We remark that there is an unavoidable limitation in Twitter Streaming API, which does not allow to retrieve true re-tweeting cascades because re-tweets always point to the original source and not to intermediate re-tweeting users BIBREF8BIBREF14; thus we adopt the only viable approach based on Twitter's public availability of data. Besides, by disentangling different interactions with multiple layers we potentially reduce the impact of this limitation on the global network properties compared to the single-layer approach used in our baseline.\nUsing the notation described in BIBREF26. we employ a multi-layer representation for Twitter diffusion networks. Sociologists have indeed recognized decades ago that it is crucial to study social systems by constructing multiple social networks where different types of ties among same individuals are used BIBREF27. Therefore, for each news article we built a multi-layer diffusion network composed of four different layers, one for each type of social interaction on Twitter platform, namely retweet (RT), reply (R), quote (Q) and mention (M), as shown in Figure FIGREF11. These networks are not necessarily node-aligned, i.e. users might be missing in some layers. We do not insert \"dummy\" nodes to represent all users as it would have severe impact on the global network properties (e.g. number of weakly connected components). Alternatively one may look at each multi-layer diffusion network as an ensemble of individual graphs BIBREF26; since global network properties are computed separately for each layer, they are not affected by the presence of any inter-layer edges.\nIn our multi-layer representation, each layer is a directed graph where we add edges and nodes for each tweet of the layer type, e.g. for the RT layer: whenever user $a$ retweets account $b$ we first add nodes $a$ and $b$ if not already present in the RT layer, then we build an edge that goes from $b$ to $a$ if it does not exists or we increment the weight by 1. Similarly for the other layers: for the R layer edges go from user $a$ (who replies) to user $b$, for the Q layer edges go from user $b$ (who is quoted by) to user $a$ and for the M layer edges go from user $a$ (who mentions) to user $b$.\nNote that, by construction, our layers do not include isolated nodes; they correspond to \"pure tweets\", i.e. tweets which have not originated any interactions with other users. However, they are present in our dataset, and their number is exploited for classification, as described below.\nWe used a set of global network indicators which allow us to encode each network layer by a tuple of features. Then we simply concatenated tuples as to represent each multi-layer network with a single feature vector. We used the following global network properties:\nNumber of Strongly Connected Components (SCC): a Strongly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $u,v$ there is a path in each direction ($u\\rightarrow v$, $v\\rightarrow u$).\nSize of the Largest Strongly Connected Component (LSCC): the number of nodes in the largest strongly connected component of a given graph.\nNumber of Weakly Connected Components (WCC): a Weakly Connected Component of a directed graph is a maximal (sub)graph where for each pair of vertices $(u, v)$ there is a path $u \\leftrightarrow v$ ignoring edge directions.\nSize of the Largest Weakly Connected Component (LWCC): the number of nodes in the largest weakly connected component of a given graph.\nDiameter of the Largest Weakly Connected Component (DWCC): the largest distance (length of the shortest path) between two nodes in the (undirected version of) largest weakly connected component of a graph.\nAverage Clustering Coefficient (CC): the average of the local clustering coefficients of all nodes in a graph; the local clustering coefficient of a node quantifies how close its neighbours are to being a complete graph (or a clique). It is computed according to BIBREF28.\nMain K-core Number (KC): a K-core BIBREF13 of a graph is a maximal sub-graph that contains nodes of internal degree $k$ or more; the main K-core number is the highest value of $k$ (in directed graphs the total degree is considered).\nDensity (d): the density for directed graphs is $d=\\frac{|E|}{|V||V-1|}$, where $|E|$ is the number of edges and $|N|$ is the number of vertices in the graph; the density equals 0 for a graph without edges and 1 for a complete graph.\nStructural virality of the largest weakly connected component (SV): this measure is defined in BIBREF14 as the average distance between all pairs of nodes in a cascade tree or, equivalently, as the average depth of nodes, averaged over all nodes in turn acting as a root; for $|V| > 1$ vertices, $SV=\\frac{1}{|V||V-1|}\\sum _i\\sum _j d_{ij}$ where $d_{ij}$ denotes the length of the shortest path between nodes $i$ and $j$. This is equivalent to compute the Wiener's index BIBREF29 of the graph and multiply it by a factor $\\frac{1}{|V||V-1|}$. In our case we computed it for the undirected equivalent graph of the largest weakly connected component, setting it to 0 whenever $V=1$.\nWe used networkx Python package BIBREF30 to compute all features. Whenever a layer is empty. we simply set to 0 all its features. In addition to computing the above nine features for each layer, we added two indicators for encoding information about pure tweets, namely the number T of pure tweets (containing URLs to a given news article) and the number U of unique users authoring those tweets. Therefore, a single diffusion network is represented by a vector with $9\\cdot 4+2=38$ entries.\nAforementioned network properties can be qualitatively explained in terms of social footprints as follows: SCC correlates with the size of the diffusion network, as the propagation of news occurs in a broadcast manner most of the time, i.e. re-tweets dominate on other interactions, while LSCC allows to distinguish cases where such mono-directionality is somehow broken. WCC equals (approximately) the number of distinct diffusion cascades pertaining to each news article, with exceptions corresponding to those cases where some cascades merge together via Twitter interactions such as mentions, quotes and replies, and accordingly LWCC and DWCC equals the size and the depth of the largest cascade. CC corresponds to the level of connectedness of neighboring users in a given diffusion network whereas KC identifies the set of most influential users in a network and describes the efficiency of information spreading BIBREF17. Finally, d describes the proportions of potential connections between users which are actually activated and SV indicates whether a news item has gained popularity with a single and large broadcast or in a more viral fashion through multiple generations.\nFor what concerns different Twitter actions, users primarily interact with each other using retweets and mentions BIBREF20.\nThe former are the main engagement activity and act as a form of endorsement, allowing users to rebroadcast content generated by other users BIBREF31. Besides, when node B retweets node A we have an implicit confirmation that information from A appeared in B's Twitter feed BIBREF12. Quotes are simply a special case of retweets with comments.\nMentions usually include personal conversations as they allow someone to address a specific user or to refer to an individual in the third person; in the first case they are located at the beginning of a tweet and they are known as replies, otherwise they are put in the body of a tweet BIBREF20. The network of mentions is usually seen as a stronger version of interactions between Twitter users, compared to the traditional graph of follower/following relationships BIBREF32.\nThe resulting dataset contains overall ∼1.7 million tweets for mainstream news, collected in a period of three weeks (February 25th, 2019-March 18th, 2019), which are associated to 6,978 news articles, and ∼1.6 million tweets for disinformation, collected in a period of three months (January 1st, 2019-March 18th, 2019) for sake of balance of the two classes, which hold 5,775 distinct articles.",

        "evidence": "Topic modeling approaches are unsupervised statistical algorithms that usually considers each document as a \"bag of words\". There were several attempts to enrich word-based topic models (=unigram topic models) with additional prior knowledge or multiword expressions.\nAndrzejewski et al. BIBREF5 incorporated knowledge by Must-Link and Cannot-Link primitives represented by a Dirichlet Forest prior. These primitives were then used in BIBREF6 , where similar words are encouraged to have similar topic distributions. However, all such methods incorporate knowledge in a hard and topic-independent way, which is a simplification since two words that are similar in one topic are not necessarily of equal importance for another topic.\nXie et al. BIBREF7 proposed a Markov Random Field regularized LDA model (MRF-LDA), which utilizes the external knowledge to improve the coherence of topic modeling. Within a document, if two words are labeled as similar according to the external knowledge, their latent topic nodes are connected by an undirected edge and a binary potential function is defined to encourage them to share the same topic label. Distributional similarity of words is calculated beforehand on a large text corpus.\nIn BIBREF8 , the authors gather so-called lexical relation sets (LR-sets) for word senses described in WordNet. The LR-sets include synonyms, antonyms and adjective-attribute related words. To adapt LR-sets to a specific domain corpus and to remove inappropriate lexical relations, the correlation matrix for word pairs in each LR-set is calculated. This matrix at the first step is used for filtrating inappropriate senses, then it is used to modify the initial LDA topic model according to the generalized Polya urn model described in BIBREF9 . The generalized Polya urn model boosts probabilities of related words in word-topic distributions.\nGao and Wen BIBREF10 presented Semantic Similarity-Enhanced Topic Model that accounts for corpus-specific word co-occurrence and word semantic similarity calculated on WordNet paths between corresponding synsets using the generalized Polya urn model. They apply their topic model for categorizing short texts.\nAll above-mentioned approaches on adding knowledge to topic models are limited to single words. Approaches using ngrams in topic models can be subdivided into two groups. The first group of methods tries to create a unified probabilistic model accounting unigrams and phrases. Bigram-based approaches include the Bigram Topic Model BIBREF11 and LDA Collocation Model BIBREF12 . In BIBREF13 the Topical N-Gram Model was proposed to allow the generation of ngrams based on the context. However, all these models are enough complex and hard to compute on real datasets.\nThe second group of methods is based on preliminary extraction of ngrams and their further use in topics generation. Initial studies of this approach used only bigrams BIBREF14 , BIBREF15 . Nokel and Loukachevitch BIBREF16 proposed the LDA-SIM algorithm, which integrates top-ranked ngrams and terms of information-retrieval thesauri into topic models (thesaurus relations were not utilized). They create similarity sets of expressions having the same word components and sum up frequencies of similarity set members if they co-occur in the same text.\nIn this paper we describe the approach to integrate whole manual thesauri into topic models together with multiword expressions.\nXie et al. [8] proposed a Markov Random Field regularized LDA model (MRFLDA), which utilizes the external knowledge to improve the coherence of topic modeling.",

Sunnis called off their civil disobedience movement but its effect on Shias was far greater than anticipated; they had the authority of two committees (Piggot committee and Allsop committee) and the practice of thirty years in support of their position. Some 1800 Shias courted arrest, including prominent Shia figures such as Syed Ali Zaheer (newly elected MLA from Allahabad-Jaunpur), the Princes of the former royal family of Awadh, Sayed Muhammad Naseer Naseer-ul-Millat the son of Maulana Nasir a respected Shia mujtahid (the eldest son, student and designated successor of Maulana Sayed Nasir Hussain of Abaqati family), Maulana Sayed Kalb-e-Husain and his son Maulana Kalb-e-Abid (both ulema of Nasirabadi family) and the brothers of Raja of Salempur and the Raja of Pirpur, important ML leaders. It was believed that Maulana Nasir himself besides the top ranking ML leaders such as Raja of Mahmudabad and Raja of Pirpur would together court arrest.

        "question": "What do the authors do to verify that joint learning tasks can benefit performance?",
        "answer": "They propose an experimental setting where there are data from two different twitter sentiment classification problems: a fine-grained and a ternary.",
        "evidence": "Our goal is to demonstrate how multitask learning can be successfully applied on the task of sentiment classification of tweets. The particularities of tweets are to be short and informal text spans. The common use of abbreviations, creative language etc., makes the sentiment classification problem challenging. To validate our hypothesis, that learning the tasks jointly can benefit the performance, we propose an experimental setting where there are data from two different twitter sentiment classification problems: a fine-grained and a ternary. We consider the fine-grained task to be our primary task as it is more challenging and obtaining bigger datasets, e.g. by distant supervision, is not straightforward and, hence we report the performance achieved for this task.\nTernary and fine-grained sentiment classification were part of the SemEval-2016 “Sentiment Analysis in Twitter” task BIBREF16 . We use the high-quality datasets the challenge organizers released. The dataset for fine-grained classification is split in training, development, development_test and test parts. In the rest, we refer to these splits as train, development and test, where train is composed by the training and the development instances. Table TABREF7 presents an overview of the data. As discussed in BIBREF16 and illustrated in the Table, the fine-grained dataset is highly unbalanced and skewed towards the positive sentiment: only INLINEFORM0 of the training examples are labeled with one of the negative classes.\nFeature representation We report results using two different feature sets. The first one, dubbed nbow, is a neural bag-of-words that uses text embeddings to generate low-dimensional, dense representations of the tweets. To construct the nbow representation, given the word embeddings dictionary where each word is associated with a vector, we apply the average compositional function that averages the embeddings of the words that compose a tweet. Simple compositional functions like average were shown to be robust and efficient in previous work BIBREF17 . Instead of training embeddings from scratch, we use the pre-trained on tweets GloVe embeddings of BIBREF10 . In terms of resources required, using only nbow is efficient as it does not require any domain knowledge. However, previous research on sentiment analysis showed that using extra resources, like sentiment lexicons, can benefit significantly the performance BIBREF3 , BIBREF2 . To validate this and examine at which extent neural networks and multitask learning benefit from such features we evaluate the models using an augmented version of nbow, dubbed nbow+. The feature space of the latter, is augmented using 1,368 extra features consisting mostly of counts of punctuation symbols ('!?#@'), emoticons, elongated words and word membership features in several sentiment lexicons. Due to space limitations, for a complete presentation of these features, we refer the interested reader to BIBREF2 , whose open implementation we used to extract them.\nEvaluation measure To reproduce the setting of the SemEval challenges BIBREF16 , we optimize our systems using as primary measure the macro-averaged Mean Absolute Error ( INLINEFORM0 ) given by: INLINEFORM1 \n\nwhere INLINEFORM0 is the number of categories, INLINEFORM1 is the set of instances whose true class is INLINEFORM2 , INLINEFORM3 is the true label of the instance INLINEFORM4 and INLINEFORM5 the predicted label. The measure penalizes decisions far from the true ones and is macro-averaged to account for the fact that the data are unbalanced. Complementary to INLINEFORM6 , we report the performance achieved on the micro-averaged INLINEFORM7 measure, which is a commonly used measure for classification.\nThe models To evaluate the multitask learning approach, we compared it with several other models. Support Vector Machines (SVMs) are maximum margin classification algorithms that have been shown to achieve competitive performance in several text classification problems BIBREF16 . SVM INLINEFORM0 stands for an SVM with linear kernel and an one-vs-rest approach for the multi-class problem. Also, SVM INLINEFORM1 is an SVM with linear kernel that employs the crammer-singer strategy BIBREF18 for the multi-class problem. Logistic regression (LR) is another type of linear classification method, with probabilistic motivation. Again, we use two types of Logistic Regression depending on the multi-class strategy: LR INLINEFORM2 that uses an one-vs-rest approach and multinomial Logistic Regression also known as the MaxEnt classifier that uses a multinomial criterion.\nBoth SVMs and LRs as discussed above treat the problem as a multi-class one, without considering the ordering of the classes. For these four models, we tuned the hyper-parameter INLINEFORM0 that controls the importance of the L INLINEFORM1 regularization part in the optimization problem with grid-search over INLINEFORM2 using 10-fold cross-validation in the union of the training and development data and then retrained the models with the selected values. Also, to account for the unbalanced classification problem we used class weights to penalize more the errors made on the rare classes. These weights were inversely proportional to the frequency of each class. For the four models we used the implementations of Scikit-learn BIBREF19 .\nFor multitask learning we use the architecture shown in Figure FIGREF2 , which we implemented with Keras BIBREF20 . The embeddings are initialized with the 50-dimensional GloVe embeddings while the output of the biLSTM network is set to dimension 50. The activation function of the hidden layers is the hyperbolic tangent. The weights of the layers were initialized from a uniform distribution, scaled as described in BIBREF21 . We used the Root Mean Square Propagation optimization method. We used dropout for regularizing the network. We trained the network using batches of 128 examples as follows: before selecting the batch, we perform a Bernoulli trial with probability INLINEFORM0 to select the task to train for. With probability INLINEFORM1 we pick a batch for the fine-grained sentiment classification problem, while with probability INLINEFORM2 we pick a batch for the ternary problem. As shown in Figure FIGREF2 , the error is backpropagated until the embeddings, that we fine-tune during the learning process. Notice also that the weights of the network until the layer INLINEFORM3 are shared and therefore affected by both tasks.\nTo tune the neural network hyper-parameters we used 5-fold cross validation. We tuned the probability INLINEFORM0 of dropout after the hidden layers INLINEFORM1 and for the biLSTM for INLINEFORM2 , the size of the hidden layer INLINEFORM3 and the probability INLINEFORM4 of the Bernoulli trials from INLINEFORM5 . During training, we monitor the network's performance on the development set and apply early stopping if the performance on the validation set does not improve for 5 consecutive epochs.\nExperimental results Table TABREF9 illustrates the performance of the models for the different data representations. The upper part of the Table summarizes the performance of the baselines. The entry “Balikas et al.” stands for the winning system of the 2016 edition of the challenge BIBREF2 , which to the best of our knowledge holds the state-of-the-art. Due to the stochasticity of training the biLSTM models, we repeat the experiment 10 times and report the average and the standard deviation of the performance achieved.\nSeveral observations can be made from the table. First notice that, overall, the best performance is achieved by the neural network architecture that uses multitask learning. This entails that the system makes use of the available resources efficiently and improves the state-of-the-art performance. In conjunction with the fact that we found the optimal probability INLINEFORM0 , this highlights the benefits of multitask learning over single task learning. Furthermore, as described above, the neural network-based models have only access to the training data as the development are hold for early stopping. On the other hand, the baseline systems were retrained on the union of the train and development sets. Hence, even with fewer resources available for training on the fine-grained problem, the neural networks outperform the baselines. We also highlight the positive effect of the additional features that previous research proposed. Adding the features both in the baselines and in the biLSTM-based architectures improves the INLINEFORM1 scores by several points.\nLastly, we compare the performance of the baseline systems with the performance of the state-of-the-art system of BIBREF2 . While BIBREF2 uses n-grams (and character-grams) with INLINEFORM0 , the baseline systems (SVMs, LRs) used in this work use the nbow+ representation, that relies on unigrams. Although they perform on par, the competitive performance of nbow highlights the potential of distributed representations for short-text classification. Further, incorporating structure and distributed representations leads to the gains of the biLSTM network, in the multitask and single task setting.\nSimilar observations can be drawn from Figure FIGREF10 that presents the INLINEFORM0 scores. Again, the biLSTM network with multitask learning achieves the best performance. It is also to be noted that although the two evaluation measures are correlated in the sense that the ranking of the models is the same, small differences in the INLINEFORM1 have large effect on the scores of the INLINEFORM2 measure.\nTo validate our hypothesis, that learning the tasks jointly can benefit the performance, we propose an experimental setting where there are data from two different twitter sentiment classification problems: a fine-grained and a ternary.",

        "answer": "In our society, freedom and safety are both valued. While many other countries may put safety first, the harsh reality for Americans is that freedom always comes before safety. Despite being equally important, Americans foolishly put their trust in freedom over safety, without realizing the dangers of those freedoms.\nThe 2nd Amendment is a commonly danger to freedom. Americans are allowed to own guns for self protection. However, since the 18th century, guns have changed. Instead of a rifle or shotgun, Americans own ARI5s and other guns that can fire hundreds of bullets per round. Security in America has also increased leaving people to question the need for a personal weapon.\nOften a result of having the freedom to easily buy and keep guns is school shootings. Teens who are depressed, lonely, suicidal, or crazy can easily buy or ise their parents guns to shoot and will other students, teachers, or themselves. In late 2022, a six year old brought his father's hand gun to school and shot his teacher. Yes, the gun was licensed and own by the father but why should any US citizen or even person feel safe in this country when the 2nd Amendment exsits? Should anyone trust their freedoms when it is easier to buy a gun than a car?\nOn the flip side, America's freedom is a gift that many other countries don't give. In 2019 when covid-19 first immerged in China, the country. went on lockdown, and in some cities, still remains so. By the third year of the pandemic, Americans learned of the extreme measures the Chinese government had taken upon its citizens, arresting those who left their homes for any reason, in the worst case. While China's laid protocols were way too extreme, Americans over the pandemic chose their freedom to not wear a mask over the safety of themselves and others, again.\nTo be clear, freedom and safety are not opposites, and countries who manage both well are impressive to be sure. But Americans are unwilling, to a dangerous level, to let go of some or any of their freedoms, even if it will benefit the overall safety of America. Freedom, in America, is valued above all, and could arguably be our most identifiable trait.",

In addition, they compare with a supervised erasure method, which requires ground-truth translations for scoring word importance (Section 4.3).",
        "evidence": "To make the conclusion convincing, we first choose two large-scale datasets that are publicly available, i.e., Chinese-English and English-French. Since English, French, and Chinese all belong to the subject-verb-object (SVO) family, we choose another very different subject-object-verb (SOV) language, Japanese, which might bring some interesting linguistic behaviors in English-Japanese translation.\nFor Chinese-English task, we use WMT17 Chinese-English dataset that consists of $20.6$M sentence pairs. For English-French task, we use WMT14 English-French dataset that comprises $35.5$M sentence pairs. For English-Japanese task, we follow BIBREF17 to use the first two sections of WAT17 English-Japanese dataset that consists of $1.9$M sentence pairs. Following the standard NMT procedure, we adopt the standard byte pair encoding (BPE) BIBREF18 with 32K merge operations for all language pairs. We believe that these datasets are large enough to confirm the rationality and validity of our experimental analyses.\nWe choose the state-of-the-art Transformer BIBREF1 model and the conventional RNN-Search model BIBREF0 as our test bed. We implement the Attribution method based on the Fairseq-py BIBREF19 framework for the above models. All models are trained on the training corpus for 100k steps under the standard settings, which achieve comparable translation results. All the following experiments are conducted on the test dataset, and we estimate the input word importance using the model generated hypotheses.\nIn the following experiments, we compare IG (Attribution) with several black-box methods (i.e., Content, Frequency, Attention) as introduced in Section SECREF8. In Section SECREF21, to ensure that the translation performance decrease attributes to the selected words instead of the perturbation operations, we randomly select the same number of words to perturb (Random), which serves as a baseline. Since there is no ranking for content words, we randomly select a set of content words as important words. To avoid the potential bias introduced by randomness (i.e., Random and Content), we repeat the experiments for 10 times and report the averaged results. We calculate the Attention importance in a similar manner as the Attribution, except that the attention scores use a max operation due to the better performance.\nWe evaluate the effectiveness of estimating word importance by the translation performance decrease. More specifically, unlike the usual way, we measure the decrease of translation performance when perturbing a set of important words that are of top-most word importance in a sentence. The more translation performance degrades, the more important the word is.\nWe use the standard BLEU score as the evaluation metric for translation performance. To make the conclusion more convincing, we conduct experiments on different types of synthetic perturbations (Section SECREF21), as well as different NMT architectures and language pairs (Section SECREF27). In addition, we compare with a supervised erasure method, which requires ground-truth translations for scoring word importance (Section SECREF30).\nIn this experiment, we investigate the effectiveness of word importance estimation methods under different synthetic perturbations. Since the perturbation on text is notoriously hard BIBREF20 due to the semantic shifting problem, in this experiment, we investigate three types of perturbations to avoid the potential bias :\nDeletion perturbation removes the selected words from the input sentence, and it can be regarded as a specific instantiation of sentence compression BIBREF21.\nMask perturbation replaces embedding vectors of the selected words with all-zero vectors BIBREF22, which is similar to Deletion perturbation except that it retains the placeholder.\nGrammatical Replacement perturbation replaces a word by another word of the same linguistic role (i.e., POS tags), yielding a sentence that is grammatically correct but semantically nonsensical BIBREF23, BIBREF24, such as “colorless green ideas sleep furiously”.\nFigure FIGREF19 illustrates the experimental results on Chinese$\\Rightarrow $English translation with Transformer. It shows that Attribution method consistently outperforms other methods against different perturbations on a various number of operations. Here the operation number denotes the number of perturbed words in a sentence. Specifically, we can make the following observations.\nUnder three different perturbations, perturbing words of top-most importance leads to lower BLEU scores than Random selected words. It confirms the existence of important words, which have greater impacts on translation performance. Furthermore, perturbing important words identified by Attribution outperforms the Random method by a large margin (more than 4.0 BLEU under 5 operations).\nFigure FIGREF19 shows that two black-box methods (i.e., Content, Frequency) perform only slightly better than the Random method. Specifically, the Frequency method demonstrates even worse performances under the Mask perturbation. Therefore, linguistic properties (such as POS tags) and the word frequency can only partially help identify the important words, but it is not as accurate as we thought. In the meanwhile, it is intriguing to explore what exact linguistic characteristics these important words reveal, which will be introduced in Section SECREF5.\nWe also evaluate the Attention method, which bases on the encoder-decoder attention scores at the last layer of Transformer. Note that the Attention method is also used to simulate the best black-box method SOCRAT, and the results show that it is more effective than black-box methods and the Random baseline. Given the powerful Attention method, Attribution method still achieves best performances under all three perturbations. Furthermore, we find that the gap between Attribution and Attention is notably large (around $1.0+$ BLEU difference). Attention method does not provide as accurate word importance as the Attribution, which exhibits the superiority of gradient-based methods and consists with the conclusion reported in the previous study BIBREF8.\nIn addition, as shown in Figure FIGREF19, the perturbation effectiveness of Deletion, Mask, and Grammatical Replacement varies from strong to weak. In the following experiments, we choose Mask as the representative perturbation operation for its moderate perturbation performance, based on which we compare two most effective methods Attribution and Attention.\nWe validate the effectiveness of the proposed approach using a different NMT architecture RNN-Search on the Chinese$\\Rightarrow $English translation task. The results are shown in Figure FIGREF20(a). We observe that the Attribution method still outperforms both Attention method and Random method by a decent margin. By comparing to Transformer, the results also reveal that the RNN-Search model is less robust to these perturbations. To be specific, under the setting of five operations and Attribution method, Transformer shows a relative decrease of $55\\%$ on BLEU scores while the decline of RNN-Search model is $64\\%$.\nWe further conduct experiments on another two language pairs (i.e., English$\\Rightarrow $French, English$\\Rightarrow $Japanese in Figures FIGREF20(b, c)) as well as the reverse directions (Figures FIGREF20(d, e, f)) using Transformer under the Mask perturbation. In all the cases, Attribution shows the best performance while Random achieves the worst result. More specifically, Attribution method shows similar translation quality degradation on all three language-pairs, which declines to around the half of the original BLEU score with five operations.\nThere exists another straightforward method, Erasure BIBREF7, BIBREF22, BIBREF25, which directly evaluates the word importance by measuring the translation performance degradation of each word. Specifically, it erases (i.e., Mask) one word from the input sentence each time and uses the BLEU score changes to denote the word importance (after normalization).\nIn Figure FIGREF31, we compare Erasure method with Attribution method under the Mask perturbation. The results show that Attribution method is less effective than Erasure method when only one word is perturbed. But it outperforms the Erasure method when perturbing 2 or more words. The results reveal that the importance calculated by erasing only one word cannot be generalized to multiple-words scenarios very well. Besides, the Erasure method is a supervised method which requires ground-truth references, and finding a better words combination is computation infeasible when erasing multiple words.\nWe close this section by pointing out that our gradient-based method consistently outperforms its black-box counterparts in various settings, demonstrating the effectiveness and universality of exploiting gradients for estimating word importance. In addition, our approach is on par with or even outperforms the supervised erasure method (on multiple-word perturbations). This is encouraging since our approach does not require any external resource and is fully unsupervised.\nTo make the conclusion more convincing, we conduct experiments on different types of synthetic perturbations (Section 4.1), as well as different NMT architectures and language pairs (Section 4.2). In addition, we compare with a supervised erasure method, which requires ground-truth translations for scoring word importance (Section 4.3).",

        "evidence": "A valuable source of information in matching user accounts, one used in traditional stylometry tasks, is the way in which people use language. A speaker or writer's choice of words depends on many factors, including the rules of grammar, message content and stylistic considerations. There is a great variety of possible ways to compare the language patterns of two people. However, first we need a method for modelling the language of a given user. Below we explain how this is done.\nMost statistical language models do not attempt to explicitly model the complete language generation process, but rather seek a compact model that adequately explains the observed linguistic data. Probabilistic models of language assign probabilities to word sequences $w_1$ . . . $w_\\ell $ , and as such the likelihood of a corpus can be used to fit model parameters as well as characterize model performance.\nN-gram language modelling BIBREF18 , BIBREF19 , BIBREF20 is an effective technique that treats words as samples drawn from a distribution conditioned on other words, usually the immediately preceding $n-1$ words, in order to capture strong local word dependencies. The probability of a sequence of $\\ell $ words, written compactly as $w_1^\\ell $ is $\\Pr (w_1^\\ell )$ and can be factored exactly as $\\Pr (w_1^\\ell ) = \\Pr (w_1) \\prod _{i=2}^\\ell \\Pr (w_i|w_1^{i-1})$ \nHowever, parameter estimation in this full model is intractable, as the number of possible word combinations grows exponentially with sequence length. N-gram models address this with the approximation $\\tilde{\\Pr }(w_i|w_{i-n+1}^{i-1}) \\approx \\Pr (w_i|w_1^{i-1})$ using only the preceding $n-1$ words for context. A bigram model ( $n=2$ ) uses the preceding word for context, while a unigram model ( $n=1$ ) does not use any context.\nFor this work, we used unigram models in Python, utilizing some components from NLTK BIBREF21 . Probability distributions were calculated using Witten-Bell smoothing BIBREF19 . Rather than assigning word $w_i$ the maximum likelihood probability estimate $p_i = \\frac{c_i}{N}$ , where $c_i$ is the number of observations of word $w_i$ and $N$ is the total number of observed tokens, Witten-Bell smoothing discounts the probability of observed words to $p_i^* = \\frac{c_i}{N+T}$ where $T$ is the total number of observed word types. The remaining $Z$ words in the vocabulary that are unobserved (i.e. where $c_i = 0$ ) are given by $p_i^* = \\frac{T}{Z(N+T)}$ .\nWe experimented with two methods for measuring the similarity between n-gram language models. In particular, we tried approaches based on KL-divergence and perplexity BIBREF22 . We also tried two methods that do not rely on n-gram models, cosine similarity of TF-IDF vectors BIBREF23 , as well as our own novel method, called the confusion model.\nThe performance of each method is shown in Table 2 . Note that all methods outperform the random baseline in both accuracy and average rank by a great margin. Below we explain each of these metrics.\nThe first metric used for measuring the distance between the language of two user accounts is the Kullback-Leibler (KL) divergence BIBREF22 between the unigram probability distribution of the corpus corresponding to the two accounts. The KL-divergence provides an asymmetric measure of dissimilarity between two probability distribution functions $p$ and $q$ and is given by: $KL(p||q) = \\int p(x)ln\\frac{p(x)}{q(x)}$ \nWe can modify the equation to prove a symmetric distance between distributions: $KL_{2}(p||q) = KL(p||q)+KL(q||p)$ \nFor this method, the similarity metric is the perplexity BIBREF22 of the unigram language model generated from one account, $p$ and evaluated on another account, $q$ . Perplexity is given as: $PP(p,q) = 2^{H(p,q)}$ \nwhere $H(p,q)$ is the cross-entropy BIBREF22 between distributions of the two accounts $p$ and $q$ . More similar models lead to smaller perplexity. As with KL-divergence, we can make perplexity symmetric: $PP_{2}(p,q) = PP(p,q)+PP(q,p)$ \nThis method outperformed the KL-divergence method in terms of average rank but not accuracy (see Table 2 ).\nPerhaps the relatively low accuracies of perplexity and KL-divergence measures should not be too surprising. These measures are most sensitive to the variations in frequencies of most common words. For instance, in its most straightforward implementation, the KL-divergence measure would be highly sensitive to the frequency of the word “the\". Although this problem might be mitigated by the removal of stop words and applying topic modelling to the texts, we believe that this issue is more nuanced than that.\nDifferent social media (such as Twitter and Facebook) are used by people for different purposes, and thus Twitter and Facebook entries by the same person are likely to be thematically different. So it is likely that straightforward comparison of language models would be inefficient for this task.\nOne possible solution for this problem is to look at users' language models not in isolation, but in comparison to the languages models of everyone else. In other words, identify features of a particular language model that are characteristic to its corresponding user, and then use these features to estimate similarity between different accounts. This is a task that Term Frequency-Inverse Document Frequency, or TF-IDF, combined with cosine similarity, can manage.\nTF-IDF is a method of converting text into numbers so that it can be represented meaningfully by a vector BIBREF23 . TF-IDF is the product of two statistics, TF or Term Frequency and IDF or Inverse Document Frequency. Term Frequency measures the number of times a term (word) occurs in a document. Since each document will be of different size, we need to normalize the document based on its size. We do this by dividing the Term Frequency by the total number of terms.\nTF considers all terms as equally important, however, certain terms that occur too frequently should have little effect (for example, the term “the\"). And conversely, terms that occur less in a document can be more relevant. Therefore, in order to weigh down the effects of the terms that occur too frequently and weigh up the effects of less frequently occurring terms, an Inverse Document Frequency factor is incorporated which diminishes the weight of terms that occur very frequently in the document set and increases the weight of terms that occur rarely. Generally speaking, the Inverse Document Frequency is a measure of how much information a word provides, that is, whether the term is common or rare across all documents.\nUsing TF-IDF, we derive a vector from the corpus of each account. We measure the similarity between two accounts using cosine similarity: $Similarity(d1,d2) = \\frac{d1 \\cdot d2}{||d1||\\times ||d2||}$ \nHere, $d1 \\cdot d2$ is the dot product of two documents, and $||d1||\\times ||d2||$ is the product of the magnitude of the two documents. Using TD-IDF and cosine similarity, we achieved significantly better results than the last two methods, with an accuracy of $0.21$ and average rank of 999.\nTF-IDF can be thought of as a heuristic measure of the extent to which different words are characteristic of a user. We came up with a new, theoretically motivated measure of “being characteristic\" for words. We considered the following setup :\nThe whole corpus of the $11,224$ Twitter and Facebook accounts was treated as one long string;\nFor each token in the string, we know the user who produced it. Imagine that we removed this information and are now making a guess as to who the user was. This will give us a probability distribution over all users;\nNow imagine that we are making a number of the following samples: randomly selecting a word from the string, taking the true user, $TU$ for this word and a guessed user, $GU$ from correspondent probability distribution. Intuitively, the more often a particular pair, $TU=U_{1}, GU=U_{2}$ appear together, the stronger is the similarity between $U_{1}$ and $U_{2}$ ;\nWe then use mutual information to measure the strength of association. In this case, it will be the mutual information BIBREF22 between random variables, $TU=U_{1}$ and $GU=U_{2}$ . This mutual information turns out to be proportional to the probabilities of $U_{1}$ and $U_{2}$ in the dataset, which is undesirable for a similarity measure. To correct for this, we divide it by the probabilities of $U_{1}$ and $U_{2}$ ;\nWe call this model the confusion model, as it evaluated the probability that $U_{1}$ will be confused for $U_{2}$ on the basis of a single word. The expression for the similarity value according to the model is $S\\times log(S)$ , where $S$ is: $S=\\sum _{w} p(w)p(U_{1}|w)p(U_{2}|w)$ \nNote that if $U_{1}=U_{2}$ , the words contributing most to the sum will be ordered by their “degree of being characteristic\". The values, $p(w)$ and $p(u|w)$ have to be estimated from the corpus. To do that, we assumed that the corpus was produced using the following auxiliary model:\nFor each token, a user is selected from a set of users by multinomial distribution;\nA word is selected from a multinomial distribution of words for this user to produce the token.\nWe used Dirichlet distributions BIBREF24 as priors over multinomials. This method outperforms all other methods with an accuracy of $0.27$ and average rank of 859.\nWe experimented with two methods for measuring the similarity between ngram language models. In particular, we tried approaches based on KL-divergence and perplexity [5]. We also tried two methods that do not rely on n-gram models, cosine similarity of TF-IDF vectors [17], as well as our own novel method, called the confusion model. The performance of each method is shown in Table 2. Note that all methods outperform the random baseline in both accuracy and average rank by a great margin. Below we explain each of these metrics.",

        "evidence": "Stylometry is defined as, \"the statistical analysis of variations in literary style between one writer or genre and another\". It is a centuries-old practice, dating back the early Renaissance. It is most often used to attribute authorship to disputed or anonymous documents. Stylometry techniques have also successfully been applied to other, non-linguistic fields, such as paintings and music. The main principles of stylometry were compiled and laid out by the philosopher Wincenty Lutosławski in 1890 in his work \"Principes de stylométrie\" BIBREF0 .\nToday, there are millions of users with accounts and profiles on many different social media and networking sites. It is not uncommon for users to have multiple accounts on different social media and networking sites. With so many networking, emailing, and photo sharing sites on the Web, a user often accumulates an abundance of account profiles. There is an increasing focus from the academic and business worlds on aggregating user information across different sites, allowing for the development of more complete user profiles. There currently exist several businesses that focus on this task BIBREF1 , BIBREF2 , BIBREF3 . These businesses use the aggregate profiles for advertising, background checks or customer service related tasks. Moreover, profile matching across social networks, can assist the growing field of social media rumor detection BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , since many malicious rumors are spread on different social media platforms by the same people, using different accounts and usernames.\nMotivated by traditional stylometry and the growing interest in matching user accounts across Internet services, we created models for Digital Stylometry, which fuses traditional stylometry techniques with big-data driven social informatics methods used commonly in analyzing social networks. Our models use linguistic and temporal activity patterns of users on different accounts to match accounts belonging to the same person. We evaluated our models on $11,224$ accounts belonging to $5,612$ distinct users on two of the largest social media networks, Twitter and Facebook. The only information that was used in our models were the time and the linguistic content of posts by the users. We intentionally did not use any other information, especially the potentially personally identifiable information that was explicitly provided by the user, such as the screen name, birthday or location. This is in accordance with traditional stylometry techniques, since people could misstate, omit, or lie about this information. Also, we wanted to show that there are implicit clues about the identities of users in the content (language) and context (time) of the users' interactions with social networks that can be used to link their accounts across different services.\nOther than the obvious technical goal, the purpose of this paper is to shed light on the relative ease with which seemingly innocuous information can be used to track users across social networks, even when signing up on different services using completely different account and profile information (such as name and birthday). This paper is as much of a technical contribution, as it is a warning to users who increasingly share a large part of their private lives on these services.\nThe rest of this paper is structured as follows. In the next sections we will review related work on linking profiles, followed by a description of our data collection and annotation efforts. After that, we discuss the linguistic, temporal and combined temporal-linguistic models developed for linking user profiles. Finally, we discuss and summarize our findings and contributions and discuss possible paths for future work.\nOur models use linguistic and temporal activity patterns of users on different accounts to match accounts belonging to the same person.

Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or nonhate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task.",

        "evidence": "Human-computer dialog/conversation is one of the most challenging problems in artificial intelligence. Given a user-issued utterance (called a query in this paper), the computer needs to provide a reply to the query. In early years, researchers have developed various domain-oriented dialogue systems, which are typically based on rules or templates BIBREF4 , BIBREF5 , BIBREF6 . Recently, open-domain conversation systems have attracted more and more attention in both academia and industry (e.g., XiaoBing from Microsoft and DuMi from Baidu). Due to high diversity, we can hardly design rules or templates in the open domain. Researchers have proposed information retrieval methods BIBREF7 and modern generative neural networks BIBREF8 , BIBREF9 to either search for a reply from a large conversation corpus or generate a new sentence as the reply.\nIn open-domain conversations, context information (one or a few previous utterances) is particularly important to language understanding BIBREF1 , BIBREF9 , BIBREF10 , BIBREF11 . As dialogue sentences are usually casual and short, a single utterance (e.g., “Thank you.” in Figure FIGREF2 ) does not convey much meaning, but its previous utterance (“...writing an essay”) provides useful background information of the conversation. Using such context will certainly benefit the conversation system.\nHowever, tracking all previous utterances as the context is unwise. First, commercial chat-bots usually place high demands on efficiency. In a retrieval-based system, for example, performing a standard process of candidate retrieval and re-ranking for each previous utterance may well exceed the time limit (which is very short, e.g., 500ms). Second, we observe that not all sentences in the current conversation session are equally important. The sentence “Want to take a walk?” is irrelevant to the current context, and should not be considered when the computer synthesizes the reply. Therefore, it raises the question of session segmentation in conversation systems.\nDocument segmentation for general-purpose corpora has been widely studied in NLP. For example, Hearst BIBREF12 proposes the TextTiling approach; she measures the similarity of neighboring sentences based on bag-of-words features, and performs segmentation by thresholding. However, such approaches are not tailored to the dialogue genre and may not be suitable for conversation session segmentation.\nIn this paper, we address the problem of session segmentation for open-domain conversations. We leverage the classic TextTiling approach, but enhance it with modern embedding-based similarity measures. Compared with traditional bag-of-words features, embeddings map discrete words to real-valued vectors, capturing underlying meanings in a continuous vector space; hence, it is more robust for noisy conversation corpora. Further, we propose a tailored method for word embedding learning. In traditional word embedding learning, the interaction between two words in a query and a reply is weaker than that within an utterance. We propose to combine a query and its corresponding reply as a “virtual sentence,” so that it provides a better way of modeling utterances between two agents.\nIn this paper, we address the problem of session segmentation for open-domain conversations.",

Since the shaping-reward adds rewards to supplement the environment (extrinsic) reward, the helpfulness of the framework in tackling sparse reward environment follows from its ability to add useful shaping rewards. We also refer the reviewer to our experiment in Sparse Cartpole in Sec. 6 which by construction is a sparse reward problem. There the agent only receives a penalty of -1 if the pole collapses and receives no other rewards otherwise. In this experiment ROSA outperforms all other baselines except for the version of BiPars which has a manually engineered shaping function already included.",
        "evidence": "Reinforcement learning (RL) offers the potential for autonomous agents to learn complex behaviours without the need for human intervention. Despite the notable success of RL in a variety domains, enabling RL algorithms to learn successfully in numerous real-world tasks remains a challenge. A key obstacle to the success of RL algorithms is the requirement of a rich reward signal that can guide the agent towards an optimal policy. In many settings of interest such as physical tasks and video games, rich informative signals of the agent's performance are not readily available. For example, in the video game Super Mario, the agent must perform sequences of hundreds of actions while receiving no rewards for it to successfully complete its task. In this setting, the sparse reward provides infrequent feedback of the agent's performance. This leads to RL algorithms requiring large numbers of samples (and high expense) for solving problems. Consequently, there is great need for RL techniques that solve these problems efficiently.\nVarious biological systems have mechanisms that produce rewards for activities that present little or no direct biological utility. Such mechanisms, which have been fashioned over millions of years are designed to provide intrinsic rewards to promote behaviours that improve chances of outcomes with biological utility. In RL, reward shaping (RS) is a tool to introduce intrinsic rewards known as shaping rewards that supplement environment reward signals. These rewards can encourage exploration and insert structural knowledge in the absence of informative environment rewards which can improve learning outcomes. In general however, RS algorithms assume hand-crafted and domainspecific shaping functions whose construction is typically highly labour intensive. This runs contrary to the aim of autonomous learning. Moreover, poor choices of shaping rewards can worsen the agent's performance. To resolve these issues, a useful shaping reward must be obtained autonomously.\nInspired by naturally occurring systems, we tackle the problem of sparse and uninformative rewards by developing a framework that autonomously constructs shaping rewards during learning. Our framework, ROSA, works by introducing an additional RL agent, Shaper, that adaptively learns to construct shaping rewards by observing Controller (the agent whose goal is to solve the environment task) while Controller learns to solve its task. This generates tailored shaping rewards without the need for domain knowledge or manual engineering. The shaping rewards supplement the environment reward and promote effective learning, our framework therefore addresses the key challenges in RS.\nThe resulting framework is a two-player nonzero-sum Markov game (MG) -an extension of Markov decision process (MDP) that involves two independent learners with distinct objectives. In our framework, the two agents that have distinct learning agendas, cooperate to achieve Controller's objective. This MG formulation confers various advantages:\n1) The shaping-reward function is constructed fully autonomously. The game also ensures the shaping reward improves Controller's performance unlike RS methods that can lower performance.\n2) By learning the shaping-reward function while Controller learns its optimal policy, Shaper learns to adaptively facilitate Controller's learning and improve Controller's performance.\n3) Both learning processes converge so Controller learns the optimal value function for its task. 4) ROSA learns subgoals to decompose complex tasks and promote complex exploration patterns.\nAn integral component of ROSA is a novel combination of RL and switching controls. This enables Controller to quickly determine useful states to learn to add and calibrate shaping rewards (i.e. the states in which adding shaping rewards improve Controller's performance) and disregard others. This is in contrast with an RL controller (i.e. Controller) which must learn its best actions at every state. This leads to Shaper quickly finding shaping rewards that guide Controller's learning process toward optimal trajectories (and away from suboptimal trajectories, c.f. Experiment 1).\nFor our two-player framework to succeed we have to overcome several obstacles. Solving MGs involves finding a stable point in which each player responds optimally to the actions of the other. In our MG, this stable point describes a pair of policies for which Shaper introduces a shaping reward that improves performance and, with that, Controller executes an optimal policy for the task. Tractable methods for solving MGs are rare with convergence of MG methods being seldom guaranteed except in a few special cases. Nevertheless, using special features in the design of our game, we prove the existence of a stable point solution of our MG. We then prove the convergence of our learning method to the solution of the game and show that the solution coincides with the solution of the Controller's problem. This ensures Shaper learns a shaping-reward function that improves Controller's performance and that Controller learns the optimal value function for the task.\nThis generates tailored shaping rewards without the need for domain knowledge or manual engineering.

        "evidence": "Mao Zedong (26 December 1893 – 9 September 1976), also known as Chairman Mao, was a Chinese communist revolutionary who was the founder of the People's Republic of China (PRC), which he led as the chairman of the Chinese Communist Party from the establishment of the PRC in 1949 until his death in 1976. Ideologically a Marxist–Leninist, his theories, military strategies, and political policies are collectively known as Maoism.\n\nMao was the son of a prosperous peasant in Shaoshan, Hunan. He supported Chinese nationalism and had an anti-imperialist outlook early in his life, and was particularly influenced by the events of the Xinhai Revolution of 1911 and May Fourth Movement of 1919. He later adopted Marxism–Leninism while working at Peking University as a librarian and became a founding member of the Chinese Communist Party (CCP), leading the Autumn Harvest Uprising in 1927. During the Chinese Civil War between the Kuomintang (KMT) and the CCP, Mao helped to found the Chinese Workers' and Peasants' Red Army, led the Jiangxi Soviet's radical land reform policies, and ultimately became head of the CCP during the Long March. Although the CCP temporarily allied with the KMT under the Second United Front during the Second Sino-Japanese War (1937–1945), China's civil war resumed after Japan's surrender, and Mao's forces defeated the Nationalist government, which withdrew to Taiwan in 1949.\n\nOn 1 October 1949, Mao proclaimed the foundation of the PRC, a Marxist–Leninist single-party state controlled by the CCP. In the following years he solidified his control through the Chinese Land Reform against landlords, the Campaign to Suppress Counterrevolutionaries, the \"Three-anti and Five-anti Campaigns\", and through a truce in the Korean War, which altogether resulted in the deaths of several million Chinese. From 1953 to 1958, Mao played an important role in enforcing command economy in China, constructing the first Constitution of the PRC, launching the industrialisation program, and initiating military projects such as the \"Two Bombs, One Satellite\" project and Project 523. His foreign policies during this time were dominated by the Sino-Soviet split which drove a wedge between China and the Soviet Union. In 1955, Mao launched the Sufan movement, and in 1957 he launched the Anti-Rightist Campaign, in which at least 550,000 people, mostly intellectuals and dissidents, were persecuted. In 1958, he launched the Great Leap Forward that aimed to rapidly transform China's economy from agrarian to industrial, which led to the deadliest famine in history and the deaths of 15–55 million people between 1958 and 1962. In 1963, Mao launched the Socialist Education Movement, and in 1966 he initiated the Cultural Revolution, a program to remove \"counter-revolutionary\" elements in Chinese society which lasted 10 years and was marked by violent class struggle, widespread destruction of cultural artifacts, and an unprecedented elevation of Mao's cult of personality. Tens of millions of people were persecuted during the Revolution, while the estimated number of deaths ranges from hundreds of thousands to millions. After years of ill health, Mao suffered a series of heart attacks in 1976 and died at the age of 82. During the Mao era, China's population grew from around 550 million to over 900 million while the government did not strictly enforce its family planning policy.\n\nWidely regarded as one of the most influential figures of the twentieth century, Mao remains a controversial figure within and outside China. Beyond politics, Mao is also known as a theorist, military strategist, and poet. Mao has been credited with transforming China from a semi-colony to a leading world power, with greatly advanced literacy, women's rights, basic healthcare, primary education and life expectancy. However, Mao's government was responsible for vast numbers of deaths, with estimates ranging from 40 to 80 million victims through starvation, persecution, prison labour, and mass executions. During his leadership tenure, China was heavily involved with other Asian communist conflicts such as the Korean War, the Vietnam War, and the Cambodian Civil War.",

In addition, we use a much larger corpus provided freely by WMT organizers when we evaluate the impact of our approach in a real machine translation campaign. It includes the paralled corpus extracted from the digital corpus of European Parliament (EPPS), the News Commentary (NC) and the web-crawled parallel data (CommonCrawl). While the number of sentences in popular TED corpora varies from 13 thousands to 17 thousands, the total number of sentences in those larger corpus is approximately 3 million sentences.\nNeural Machine Translation Setup. All experiments have been conducted using NMT framework Nematus, Following the work of Sennrich2016a, subword segmentation is handled in the prepocessing phase using Byte-Pair Encoding (BPE). Excepts stated clearly in some experiments, we set the number of BPE merging operations at 39500 on the joint of source and target data. When training all NMT systems, we take out the sentence pairs exceeding 50-word length and shuffle them inside every minibatch. Our short-list vocabularies contain 40,000 most frequent words while the others are considered as rare words and applied the subword translation. We use an 1024-cell GRU layer and 1000-dimensional embeddings with dropout at every layer with the probability of 0.2 in the embedding and hidden layers and 0.1 in the input and ourput layers. We trained our systems using gradient descent optimization with Adadelta BIBREF13 on minibatches of size 80 and the gradient is rescaled whenever its norm exceed 1.0. All the trainings last approximately seven days if the early-stopping condition could not be reached. At a certain time, an external evaluation script on BLEU BIBREF14 is conducted on a development set to decide the early-stopping condition. This evaluation script has also being used to choose the model archiving the best BLEU on the development set instead of the maximal loglikelihood between the translations and target sentences while training. In translation, the framework produces INLINEFORM0 -best candidates and we then use a beam search with the beam size of 12 to get the best translation.\nAll experiments have been conducted using NMT framework Nematus6 , Following the work of Sennrich et al.

As mentioned in the paper, calculating the hardness degree of samples does not require the true label of samples. Nevertheless, since we had access to the true labels of CIFAR10 and CIFAR100 test samples, we depict Figure 2 (Figure 6) to give more intuition about the hardness degree of samples. To depict this figure, we first calculate the hardness degree of CIFAR10 and CIFAR100 test samples and then partition them into ten groups based on their hardness degree. Notably, the number of samples in each group is different. Afterward, we calculate what percentage of samples in each group is classified incorrectly. The figure demonstrates that the misclassification rate is increased by increasing the hardness degree of samples. In other words, there is a strong positive correlation between the hardness degree of samples and the misclassification rate. Figure 6 indicates the percentage of samples in each hardness degree range by a green curve. We have added an example to Appendix B to clarify Figure 6.",

        "evidence": "Following developing news stories is imperative to making real-time decisions on important political and public safety matters. Given the abundance of media providers and languages, this endeavor is an extremely difficult task. As such, there is a strong demand for automatic clustering of news streams, so that they can be organized into stories or themes for further processing. Performing this task in an online and efficient manner is a challenging problem, not only for newswire, but also for scientific articles, online reviews, forum posts, blogs, and microblogs.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream. In this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes. For example, for news articles, we would want to cluster them into related news stories.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. Our clustering approach is part of a larger media monitoring project to solve the problem of monitoring massive text and TV/Radio streams (speech-to-text). In particular, media monitors write intelligence reports about the most relevant events, and being able to search, visualize and explore news clusters assists in gathering more insight about a particular story. Since relevant events may be spawned from any part of the world (and from many multilingual sources), it becomes imperative to cluster news across different languages.\nIn terms of granularity, the type of story clusters we are interested in are the group of articles which, for example : (i) Narrate recent air-strikes in Eastern Ghouta (Syria); (ii) Describe the recent launch of Space X's Falcon Heavy rocket.\nOur main contributions are as follows:  • We develop a system that aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. As discussed in the introduction, this is a highly relevant task for the use-case of media monitoring.  • We formulate the problem of online multilingual document clustering and the representation that such clustering takes by interlacing the problem  of monolingual clustering with crosslingual clustering. The representation of our clusters is interpretable, and similarly to topic models, consists of a set of keywords and weights associated with the relevant cluster. In our formulation, a monolingual cluster is a group of documents, and a crosslingual cluster is a group of monolingual clusters in different languages.  • We compare our approach to our own implementation of a state-of-the-art streaming method, and show much superior results for a dataset in English, Spanish and German.",

        "evidence": "We compare performances of our model with the implementation of BIBREF13 and the results are shown in Table TABREF43 . Our model obtains better performances in Multi-Domain scenario with an average improvement of 4.5%, where datasets are product reviews on different domains with similar sequence lengths and the same class number, thus producing stronger correlations. Multi-Cardinality scenario also achieves significant improvements of 2.77% on average, where datasets are movie reviews with different cardinalities.\nHowever, Multi-Objective scenario benefits less from multi-task learning due to lacks of salient correlation among sentiment, topic and question type. The QC dataset aims to classify each question into six categories and its performance even gets worse, which may be caused by potential noises introduced by other tasks. In practice, the structure of our model is flexible, as couplings and fusions between some empirically unrelated tasks can be removed to alleviate computation costs.\nWe further explore the influence of INLINEFORM0 in TOS on our model, which can be any positive integer. A higher value means larger and more various samples combinations, while requires higher computation costs.\nFigure FIGREF45 shows the performances of datasets in Multi-Domain scenario with different INLINEFORM0 . Compared to INLINEFORM1 , our model can achieve considerable improvements when INLINEFORM2 as more samples combinations are available. However, there are no more salient gains as INLINEFORM3 gets larger and potential noises from other tasks may lead to performance degradations. For a trade-off between efficiency and effectiveness, we determine INLINEFORM4 as the optimal value for our experiments.\nIn order to measure the correlation strength between two task INLINEFORM0 and INLINEFORM1 , we learn them jointly with our model and define Pair-wise Performance Gain as INLINEFORM2 , where INLINEFORM3 are the performances of tasks INLINEFORM4 and INLINEFORM5 when learned individually and jointly.\nWe calculate PPGs for every two tasks in Table TABREF35 and illustrate the results in Figure FIGREF47 , where darkness of colors indicate strength of correlation. It is intuitive that datasets of Multi-Domain scenario obtain relatively higher PPGs with each other as they share similar cardinalities and abundant low-level linguistic characteristics. Sentences of QC dataset are much shorter and convey unique characteristics from other tasks, thus resulting in quite lower PPGs.\nIn practice, the structure of our model is flexible, as couplings and fusions between some empirically unrelated tasks can be removed to alleviate computation costs.",

        "evidence": "Space exploration stared during the late 1920s leading to the first crewed rocket cars and rocket planes, then there was the US and Soviet activities from 1950 onwards",
        "answer": "The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the spectacular public demonstrations of ground and air vehicles drew large crowds, as well as caused global public excitement as so-called \"Rocket Rumble\" and had a large long-lasting impact on later spaceflight pioneers like Wernher von Braun. Common rationales for exploring space include advancing scientific research, national prestige, uniting different nations, ensuring the future survival of humanity, and developing military and strategic advantages against other countries. The early era of space exploration was driven by a \"Space Race\" between the Soviet Union and the United States. The launch of the first human-made object to orbit Earth, the Soviet Union's Sputnik 1, on 4 October 1957, and the first Moon landing by the American Apollo 11 mission on 20 July 1969 are often taken as landmarks for this initial period. The Soviet space program achieved many of the first milestones, including the first living being in orbit in 1957, the first human spaceflight (Yuri Gagarin aboard Vostok 1) in 1961, the first spacewalk (by Alexei Leonov) on 18 March 1965, the first automatic landing on another celestial body in 1966, and the launch of the first space station (Salyut 1) in 1971. After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station (ISS).\n\nWith the substantial completion of the ISS following STS-133 in March 2011, plans for space exploration by the U.S. remain in flux. Constellation, a Bush Administration program for a return to the Moon by 2020 was judged inadequately funded and unrealistic by an expert review panel reporting in 2009. The Obama Administration proposed a revision of Constellation in 2010 to focus on the development of the capability for crewed missions beyond low Earth orbit (LEO), envisioning extending the operation of the ISS beyond 2020, transferring the development of launch vehicles for human crews from NASA to the private sector, and developing technology to enable missions to beyond LEO, such as Earth–Moon L1, the Moon, Earth–Sun L2, near-Earth asteroids, and Phobos or Mars orbit.",

Sir Walter is a widower who is conceited and selfish, and spends lavishly and beyond his means, which has forced the family to retrench by renting out their landed estate and relocating to lower-cost Bath.  \n\nAnne is wise and kind but, at 26, is past her prime.  At 19, Anne fell in love with, and accepted a marriage proposal from, Frederick Wentworth, a promising naval commander who is of a lower social status than Anne.  Anne is persuaded by her family (father and older sister) and close friend (Lady Russell) to break off the proposal.  \n\nThe novel starts with the family planning for their relocation to Bath, and the Elliots have coincidentally rented their home to the sister and brother-in-law of Frederick Wentworth, now a naval captain.  This provides Captain Wentworth with the opportunity to re-enter Anne’s life and her social circle.  Captain Wentworth has achieved much success and wealth from his naval career.  While Anne immediately notices and admires Captain Wentworth, he initially remains cold to her and commented that she has aged significantly since he last saw her.

        "evidence": "Named entity typing is the task of detecting the type (e.g., person, location, or organization) of a named entity in natural language text. Entity type information has shown to be useful in natural language tasks such as question answering BIBREF0 , knowledge-base population BIBREF1 , BIBREF2 , and co-reference resolution BIBREF3 . Motivated by its application to downstream tasks, recent work on entity typing has moved beyond standard coarse types towards finer-grained semantic types with richer ontologies BIBREF0 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . Rather than assuming an entity can be uniquely categorized into a single type, the task has been approached as a multi-label classification problem: e.g., in “... became a top seller ... Monopoly is played in 114 countries. ...” (fig:arch), “Monopoly” is considered both a game as well as a product.\nThe state-of-the-art approach BIBREF8 for fine-grained entity typing employs an attentive neural architecture to learn representations of the entity mention as well as its context. These representations are then combined with hand-crafted features (e.g., lexical and syntactic features), and fed into a linear classifier with a fixed threshold. While this approach outperforms previous approaches which only use sparse binary features BIBREF4 , BIBREF6 or distributed representations BIBREF9 , it has a few drawbacks: (1) the representations of left and right contexts are learnt independently, ignoring their mutual connection; (2) the attention on context is computed solely upon the context, considering no alignment to the entity; (3) document-level contexts which could be useful in classification are not exploited; and (4) hand-crafted features heavily rely on system or human annotations.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts. Further, we find that adaptive classification thresholds leads to further improvements. Experiments demonstrate that our approach, without any reliance on hand-crafted features, outperforms prior work on three benchmark datasets.\nIn this paper, we focus on designing different variants of using BERT on the extractive summarization task and showing their results on CNN/Dailymail and NYT datasets.",

        "answer": "To identify text segments from text documents without labeled data and that only requires the current document itself, rather than an entire training corpus linked to the target document.",
        "evidence": "Extracting data elements such as study descriptors from publication full texts is an essential step in a number of tasks including systematic review preparation BIBREF0 , construction of reference databases BIBREF1 , and knowledge discovery BIBREF2 . These tasks typically involve domain experts identifying relevant literature pertaining to a specific research question or a topic being investigated, identifying passages in the retrieved articles that discuss the sought after information, and extracting structured data from these passages. The extracted data is then analyzed, for example to assess adherence to existing guidelines BIBREF1 . Figure FIGREF2 shows an example text excerpt with information relevant to a specific task (assessment of adherence to existing guidelines BIBREF1 ) highlighted.\nExtracting the data elements needed in these tasks is a time-consuming and at present a largely manual process which requires domain expertise. For example, in systematic review preparation, information extraction generally constitutes the most time consuming task BIBREF4 . This situation is made worse by the rapidly expanding body of potentially relevant literature with more than one million papers added into PubMed each year BIBREF5 . Therefore, data annotation and extraction presents an important challenge for automation.\nA typical approach to automated identification of relevant information in biomedical texts is to infer a prediction model from labeled training data – such a model can then be used to assign predicted labels to new data instances. However, obtaining training data for creating such prediction models can be very costly as it involves the step which these models are trying to automate – manual data extraction. Furthermore, depending on the task at hand, the types of information being extracted may vary significantly. For example, in systematic reviews of randomized controlled trials this information generally includes the patient group, the intervention being tested, the comparison, and the outcomes of the study (PICO elements) BIBREF4 . In toxicology research the extraction may focus on routes of exposure, dose, and necropsy timing BIBREF1 . Previous work has largely focused on identifying specific pieces of information such as biomedical events BIBREF6 or PICO elements BIBREF0 . However, depending on the domain and the end goal of the extraction, these may be insufficient to comprehensively describe a given study.\nTherefore, in this paper we focus on unsupervised methods for identifying text segments (such as sentences or fixed length sequences of words) relevant to the information being extracted. We develop a model that can be used to identify text segments from text documents without labeled data and that only requires the current document itself, rather than an entire training corpus linked to the target document. More specifically, we utilize representation learning methods BIBREF7 , where words or phrases are embedded into the same vector space. This allows us to compute semantic relatedness among text fragments, in particular sentences or text segments in a given document and a short description of the type of information being extracted from the document, by using similarity measures in the feature space. The model has the potential to speed up identification of relevant segments in text and therefore to expedite annotation of domain specific information without reliance on costly labeled data.\nWe have developed and tested our approach on a reference database of rodent uterotropic bioassays BIBREF1 which are labeled according to their adherence to test guidelines set forth in BIBREF3 . Each study in the database is assigned a label determining whether or not it met each of six main criteria defined by the guidelines; however, the database does not contain sentence-level annotations or any information about where the criteria was mentioned in each publication. Due to the lack of fine-grained annotations, supervised learning methods cannot be easily applied to aid annotating new publications or to annotate related but distinct types of studies. This database therefore presents an ideal use-case for unsupervised approaches.\nWhile our approach doesn't require any labeled data to work, we use the labels available in the dataset to evaluate the approach. We train a binary classification model for identifying publications which satisfied given criteria and show the model performs better when trained on relevant sentences identified by our method than when trained on sentences randomly picked from the text. Furthermore, for three out of the six criteria, a model trained solely on the relevant sentences outperforms a model which utilizes full text. The results of our evaluation support the intuition that semantic relatedness to criteria descriptions can help in identifying text sequences discussing sought after information.\nThere are two main contributions of this work. We present an unsupervised method that employs representation learning to identify text segments from publication full text which are relevant to/contain specific sought after information (such as number of dose groups). In addition, we explore a new dataset which hasn't been previously used in the field of information extraction.\nThe remainder of this paper is organized as follows. In the following section we provide more details of the task and the dataset used in this study. In Section SECREF3 we describe our approach. In Section SECREF4 we evaluate our model and discuss our results. In Section SECREF5 we compare our work to existing approaches. Finally, in Section SECREF6 we provide ideas for further study.\nTherefore, in this paper we focus on unsupervised methods for identifying text segments (such as sentences or fixed length sequences of words) relevant to the information being extracted. We develop a model that can be used to identify text segments from text documents without labeled data and that only requires the current document itself, rather than an entire training corpus linked to the target document.",

This development occurred independently in several global locations from as early as 9000–7000 BC in Mesopotamia to 3500–3000 BC in the Americas. People first domesticated the most important dairy animals – cattle, sheep and goats – in Southwest Asia, although domestic cattle had been independently derived from wild aurochs populations several times since. Initially animals were kept for meat, and archaeologist Andrew Sherratt has suggested that dairying, along with the exploitation of domestic animals for hair and labor, began much later in a separate secondary products revolution in the fourth millennium BC. Sherratt's model is not supported by recent findings, based on the analysis of lipid residue in prehistoric pottery, that shows that dairying was practiced in the early phases of agriculture in Southwest Asia, by at least the seventh millennium BC. From Southwest Asia domestic dairy animals spread to Europe (beginning around 7000 BC but did not reach Britain and Scandinavia until after 4000 BC), and South Asia (7000–5500 BC). The first farmers in central Europe and Britain milked their animals. Pastoral and pastoral nomadic economies, which rely predominantly or exclusively on domestic animals and their products rather than crop farming, were developed as European farmers moved into the Pontic–Caspian steppe in the fourth millennium BC, and subsequently spread across much of the Eurasian steppe.

        "answer": "Structural biology is a field that is many centuries old which, as defined by the Journal of Structural Biology, deals with structural analysis of living material (formed, composed of, and/or maintained and refined by living cells) at every level of organization. Early structural biologists throughout the 19th and early 20th centuries were primarily only able to study structures to the limit of the naked eye's visual acuity and through magnifying glasses and light microscopes.\n\nIn the 20th century, a variety of experimental techniques were developed to examine the 3D structures of biological molecules. The most prominent techniques are X-ray crystallography, nuclear magnetic resonance, and electron microscopy. Through the discovery of X-rays and its applications to protein crystals, structural biology was revolutionized, as now scientists could obtain the three-dimensional structures of biological molecules in atomic detail. Likewise, NMR spectroscopy allowed information about protein structure and dynamics to be obtained. Finally, in the 21st century, electron microscopy also saw a drastic revolution with the development of more coherent electron sources, aberration correction for electron microscopes, and reconstruction software that enabled the successful implementation of high resolution cryo-electron microscopy, thereby permitting the study of individual proteins and molecular complexes in three-dimensions at angstrom resolution.\n\nWith the development of these three techniques, the field of structural biology expanded and also became a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, RNA or DNA, made up of nucleotides, and membranes, made up of lipids), how they acquire the structures they have, and how alterations in their structures affect their function. This subject is of great interest to biologists because macromolecules carry out most of the functions of cells, and it is only by coiling into specific three-dimensional shapes that they are able to perform these functions. This architecture, the \"tertiary structure\" of molecules, depends in a complicated way on each molecule's basic composition, or \"primary structure.\" At lower resolutions, tools such as FIB-SEM tomography have allowed for greater understanding of cells and their organelles in 3-dimensions, and how each hierarchical level of various extracellular matrices contributes to function (for example in bone). In the past few years it has also become possible to predict highly accurate physical molecular models to complement the experimental study of biological structures. Computational techniques such as Molecular Dynamics simulations can be used in conjunction with empirical structure determination strategies to extend and study protein structure, conformation and function.",

        "answer": "No.",
        "evidence": "Despite the rapid progress of deep learning techniques on diverse supervised learning tasks, these models remain brittle to subtle shifts in the data distribution. Even when the permissible changes are confined to barely-perceptible perturbations, training robust models remains an open challenge. Following the discovery that imperceptible attacks could cause image recognition models to misclassify examples BIBREF0 , a veritable sub-field has emerged in which authors iteratively propose attacks and countermeasures.\nFor all the interest in adversarial computer vision, these attacks are rarely encountered outside of academic research. However, adversarial misspellings constitute a longstanding real-world problem. Spammers continually bombard email servers, subtly misspelling words in efforts to evade spam detection while preserving the emails' intended meaning BIBREF1 , BIBREF2 . As another example, programmatic censorship on the Internet has spurred communities to adopt similar methods to communicate surreptitiously BIBREF3 .\nIn this paper, we focus on adversarially-chosen spelling mistakes in the context of text classification, addressing the following attack types: dropping, adding, and swapping internal characters within words. These perturbations are inspired by psycholinguistic studies BIBREF4 , BIBREF5 which demonstrated that humans can comprehend text altered by jumbling internal characters, provided that the first and last characters of each word remain unperturbed.\nFirst, in experiments addressing both BiLSTM and fine-tuned BERT models, comprising four different input formats: word-only, char-only, word+char, and word-piece BIBREF6 , we demonstrate that an adversary can degrade a classifier's performance to that achieved by random guessing. This requires altering just two characters per sentence. Such modifications might flip words either to a different word in the vocabulary or, more often, to the out-of-vocabulary token UNK. Consequently, adversarial edits can degrade a word-level model by transforming the informative words to UNK. Intuitively, one might suspect that word-piece and character-level models would be less susceptible to spelling attacks as they can make use of the residual word context. However, our experiments demonstrate that character and word-piece models are in fact more vulnerable. We show that this is due to the adversary's effective capacity for finer grained manipulations on these models. While against a word-level model, the adversary is mostly limited to UNK-ing words, against a word-piece or character-level model, each character-level add, drop, or swap produces a distinct input, providing the adversary with a greater set of options.\nSecond, we evaluate first-line techniques including data augmentation and adversarial training, demonstrating that they offer only marginal benefits here, e.g., a BERT model achieving $90.3$ accuracy on a sentiment classification task, is degraded to $64.1$ by an adversarially-chosen 1-character swap in the sentence, which can only be restored to $69.2$ by adversarial training.\nThird (our primary contribution), we propose a task-agnostic defense, attaching a word recognition model that predicts each word in a sentence given a full sequence of (possibly misspelled) inputs. The word recognition model's outputs form the input to a downstream classification model. Our word recognition models build upon the RNN-based semi-character word recognition model due to BIBREF7 . While our word recognizers are trained on domain-specific text from the task at hand, they often predict UNK at test time, owing to the small domain-specific vocabulary. To handle unobserved and rare words, we propose several backoff strategies including falling back on a generic word recognizer trained on a larger corpus. Incorporating our defenses, BERT models subject to 1-character attacks are restored to $88.3$ , $81.1$ , $78.0$ accuracy for swap, drop, add attacks respectively, as compared to $69.2$ , $63.6$ , and $50.0$ for adversarial training\nFourth, we offer a detailed qualitative analysis, demonstrating that a low word error rate alone is insufficient for a word recognizer to confer robustness on the downstream task. Additionally, we find that it is important that the recognition model supply few degrees of freedom to an attacker. We provide a metric to quantify this notion of sensitivity in word recognition models and study its relation to robustness empirically. Models with low sensitivity and word error rate are most robust.\nFourth, we offer a detailed qualitative analysis, demonstrating that a low word error rate alone is insufficient for a word recognizer to confer robust ness on the downstream task.",

Hence, automatic metrics that compare the generated text to one or more reference texts are routinely used to compare models BIBREF7 . For table-to-text generation, automatic evaluation has largely relied on BLEU BIBREF8 and ROUGE BIBREF9 . The underlying assumption behind these metrics is that the reference text is gold-standard, i.e., it is the ideal target text that a system should generate. In practice, however, when datasets are collected automatically and heuristically, the reference texts are often not ideal. Figure FIGREF2 shows an example from the WikiBio dataset BIBREF0 . Here the reference contains extra information which no system can be expected to produce given only the associated table. We call such reference texts divergent from the table.\nWe show that existing automatic metrics, including BLEU, correlate poorly with human judgments when the evaluation sets contain divergent references (§ SECREF36 ). For many table-to-text generation tasks, the tables themselves are in a pseudo-natural language format (e.g., WikiBio, WebNLG BIBREF6 , and E2E-NLG BIBREF10 ). In such cases we propose to compare the generated text to the underlying table as well to improve evaluation. We develop a new metric, PARENT (Precision And Recall of Entailed N-grams from the Table) (§ SECREF3 ). When computing precision, PARENT effectively uses a union of the reference and the table, to reward correct information missing from the reference. When computing recall, it uses an intersection of the reference and the table, to ignore extra incorrect information in the reference. The union and intersection are computed with the help of an entailment model to decide if a text n-gram is entailed by the table. We show that this method is more effective than using the table as an additional reference.

        "answer": "The authors experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set.",

        "evidence": "Inspired by the multi-source NMT as additional parallel data in several languages are expected to benefit single translations, we aim to develop a NMT-based approach toward an universal framework to perform multilingual translation. Our solution features two treatments: 1) Coding the words in different languages as different words in the language-mixed vocabularies and 2) Forcing the NMT to translating a representation of source sentences into the sentences in a desired target language.\nLanguage-specific Coding. When the encoder of a NMT system considers words across languages as different words, with a well-chosen architecture, it is expected to be able to learn a good representation of the source words in an embedding space in which words carrying similar meaning would have a closer distance to each others than those are semantically different. This should hold true when the words have the same or similar surface form, such as (@de@Obama; @en@Obama) or (@de@Projektion; @en@projection). This should also hold true when the words have the same or similar meaning across languages, such as (@en@car; @en@automobile) or (@de@Flussufer; @en@bank). Our encoder then acts similarly to the one of multi-source approach BIBREF10 , collecting additional information from other sources for better translations, but with a much simpler embedding function. Unlike them, we need only one encoder, so we could reduce the number of parameters to learn. Furthermore, we neither need to change the network architecture nor depend on which recurrent unit (GRU, LSTM or simple RNN) is currently using in the encoder.\nWe could apply the same trick to the target sentences and thus enable many-to-many translation capability of our NMT system. Similar to the multi-target translation BIBREF8 , we exploit further the correlation in semantics of those target sentences across different languages. The main difference between our approach and the work of BIBREF8 is that we need only one decoder for all target languages. Given one encoder for multiple source languages and one decoder for multiple target languages, it is trivial to incorporate the attention mechanism as in the case of a regular NMT for single language translation. In training, the attention layers were directed to learn relevant alignments between words in specific language pair and forward the produced context vector to the decoder. Now we rely totally on the network to learn good alignments between source and target sides. In fact, giving more information, our system are able to form nice alignments.\nIn comparison to other research that could perform complete multi-task learning, e.g. the work from BIBREF9 or the approach proposed by BIBREF11 , our method is able to accommodate the attention layers seemlessly and easily. It also draws a clear distinction from those works in term of the complexity of the whole network: considerably less parameters to learn, thus reduces overfitting, with a conventional attention mechanism and a standard training procedure.\nTarget Forcing. While language-specific coding allows us to implement a multilingual attention-based NMT, there are two issues we have to consider before training the network. The first is that the number of rare words would increase in proportion with the number of languages involved. This might be solved by applying a rare word treatment method with appropriate awareness of the vocabularies' size. The second one is more problematic: Ambiguity level in the translation process definitely increases due to the additional introduction of words having the same or similar meaning across languages at both source and target sides. We deal with the problem by explicitly forcing the attention and translation to the direction that we prefer, expecting the information would limit the ambiguity to the scope of one language instead of all target languages. We realize this idea by adding at the beginning and at the end of every source sentences a special symbol indicating the language they would be translated into. For example, in a multilingual NMT, when a source sentence is German and the target language is English, the original sentence (already language-specific coded) is:\n@de@darum @de@geht @de@es @de@in @de@meinem @de@Vortrag\nNow when we force it to be translated into English, the target-forced sentence becomes:\n<E> @de@darum @de@geht @de@es @de@in @de@meinem @de@Vortrag <E>\nDue to the nature of recurrent units used in the encoder and decoder, in training, those starting symbols encourage the network learning the translation of following target words in a particular language pair. In testing time, information of the target language we provided help to limit the translated candidates, hence forming the translation in the desired language.\nFigure FIGREF8 illustrates the essence of our approach. With two steps in the preprocessing phase, namely language-specific coding and target forcing, we are able to employ multilingual attention-based NMT without any special treatment in training such a standard architecture. Our encoder and attention-enable decoder can be seen as a shared encoder and decoder across languages, or an universal encoder and decoder. The flexibitily of our approach allow us to integrate any language into source or target side. As we will see in Section SECREF4 , it has proven to be extremely helpful not only in low-resourced scenarios but also in translation of well-resourced language pairs as it provides a novel way to make use of large monolingual corpora in NMT.\nFigure 1 illustrates the essence of our approach. With two steps in the preprocessing phase, namely language-specific coding and target forcing, we are able to employ multilingual attention-based NMT without any special treatment in training such a standard architecture.

        "answer": "Discarding useless features.",
        "evidence": "In recent years, the proliferation of fake news with various content, high-speed spreading, and extensive influence has become an increasingly alarming issue. A concrete instance was cited by Time Magazine in 2013 when a false announcement of Barack Obama's injury in a White House explosion “wiped off 130 Billion US Dollars in stock value in a matter of seconds\". Other examples, an analysis of the US Presidential Election in 2016 BIBREF0 revealed that fake news was widely shared during the three months prior to the election with 30 million total Facebook shares of 115 known pro-Trump fake stories and 7.6 million of 41 known pro-Clinton fake stories. Therefore, automatically detecting fake news has attracted significant research attention in both industries and academia.\nMost existing methods devise deep neural networks to capture credibility features for fake news detection. Some methods provide in-depth analysis of text features, e.g., linguistic BIBREF1, semantic BIBREF2, emotional BIBREF3, stylistic BIBREF4, etc. On this basis, some work additionally extracts social context features (a.k.a. meta-data features) as credibility features, including source-based BIBREF5, user-centered BIBREF6, post-based BIBREF7 and network-based BIBREF8, etc. These methods have attained a certain level of success. Additionally, recent researches BIBREF9, BIBREF10 find that doubtful and opposing voices against fake news are always triggered along with its propagation. Fake news tends to provoke controversies compared to real news BIBREF11, BIBREF12. Therefore, stance analysis of these controversies can serve as valuable credibility features for fake news detection.\nThere is an effective and novel way to improve the performance of fake news detection combined with stance analysis, which is to build multi-task learning models to jointly train both tasks BIBREF13, BIBREF14, BIBREF15. These approaches model information sharing and representation reinforcement between the two tasks, which expands valuable features for their respective tasks. However, prominent drawback to these methods and even typical multi-task learning methods, like the shared-private model, is that the shared features in the shared layer are equally sent to their respective tasks without filtering, which causes that some useless and even adverse features are mixed in different tasks, as shown in Figure FIGREF2(a). By that the network would be confused by these features, interfering effective sharing, and even mislead the predictions.\nTo address the above problems, we design a sifted multi-task learning model with filtering mechanism (Figure FIGREF2(b)) to detect fake news by joining stance detection task. Specifically, we introduce a selected sharing layer into each task after the shared layer of the model for filtering shared features. The selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks. Besides, to better capture long-range dependencies and improve the parallelism of the model, we apply transformer encoder module BIBREF16 to our model for encoding input representations of both tasks. Experimental results reveal that the proposed model outperforms the compared methods and gains new benchmarks.\nIn summary, the contributions of this paper are as follows:\nWe explore a selected sharing layer relying on gate mechanism and attention mechanism, which can selectively capture valuable shared features between tasks of fake news detection and stance detection for respective tasks.\nThe transformer encoder is introduced into our model for encoding inputs of both tasks, which enhances the performance of our method by taking advantages of its long-range dependencies and parallelism.\nExperiments on two public, widely used fake news datasets demonstrate that our method significantly outperforms previous state-of-the-art methods.\nThe selected sharing layer composes of two cells: gated sharing cell for discarding useless features and attention sharing cell for focusing on features that are conducive to their respective tasks.",

However, note that we did not have access to the training data of ClaimBuster, which is not publicly available, and we thus train on our dataset (described above).\nSentiment (2 S features): Some sentences are highly negative, which can signal the presence of an interesting claim to check, as the two example sentences below show (from the 1st and the 2nd presidential debates):\n\nWe used the NRC sentiment lexicon BIBREF15 as a source of words and $n$-grams with positive/negative sentiment, and we counted the number of positive and of negative words in the target sentence. These features are different from those in the CB features above, where these lexicons were not used.\nNamed entities (NE) (1 S feature): Sentences that contain named entity mentions are more likely to contain a claim that is worth fact-checking as they discuss particular people, organizations, and locations. Thus, we have a feature that counts the number of named entity mentions in the target sentence; we use the NLTK toolkit for named entity recognition BIBREF16. Unlike the CB features above, here we only have one feature; we also use a different toolkit for named entity recognition.\nLinguistic features (9 S features): We count the number of words in each sentence that belong to each of the following lexicons: Language Bias lexicon BIBREF17, Opinion Negative and Positive Words BIBREF18, Factives and Assertive Predicates BIBREF19, Hedges BIBREF20, Implicatives BIBREF21, and Strong and Weak subjective words. Some examples are shown in Table TABREF12.\nTense (1 S feature): Most of the check-worthy claims mention past events. In order to detect when the speaker is making a reference to the past or s/he is talking about his/her future vision and plans, we include a feature with three values—indicating whether the text is in past, present, or future tense. The feature is extracted from the verbal expressions, using POS tags and a list of auxiliary verbs and phrases such as will, have to, etc.\nLength (1 S feature): Shorter sentences are generally less likely to contain a check-worthy claim.

Bioinformatics has been used for in silico analyses of biological queries using computational and statistical techniques.\n\nBioinformatics includes biological studies that use computer programming as part of their methodology, as well as specific analysis \"pipelines\" that are repeatedly used, particularly in the field of genomics. Common uses of bioinformatics include the identification of candidates genes and single nucleotide polymorphisms (SNPs). Often, such identification is made with the aim to better understand the genetic basis of disease, unique adaptations, desirable properties (esp. in agricultural species), or differences between populations. In a less formal way, bioinformatics also tries to understand the organizational principles within nucleic acid and protein sequences, called proteomics.\n\nImage and signal processing allow extraction of useful results from large amounts of raw data.

        "answer": "Beceuse of the amount of information on the Web.",
        "evidence": "Web 2.0 has had a substantial impact on communication and relationships in today's society. Children and teenagers go online more frequently, at younger ages, and in more diverse ways (e.g. smartphones, laptops and tablets). Although most of teenagers' Internet use is harmless and the benefits of digital communication are evident, the freedom and anonymity experienced online makes young people vulnerable, with cyberbullying being one of the major threats BIBREF0 , BIBREF1 , BIBREF2 .\nBullying is not a new phenomenon, and cyberbullying has manifested itself as soon as digital technologies have become primary communication tools. On the positive side, social media like blogs, social networking sites (e.g. Facebook) and instant messaging platforms (e.g. WhatsApp) make it possible to communicate with anyone and at any time. Moreover, they are a place where people engage in social interaction, offering the possibility to establish new relationships and maintain existing friendships BIBREF3 , BIBREF4 . On the negative side however, social media increase the risk of children being confronted with threatening situations including grooming or sexually transgressive behaviour, signals of depression and suicidal thoughts, and cyberbullying. Users are reachable 24/7 and are often able to remain anonymous if desired: this makes social media a convenient way for bullies to target their victims outside the school yard.\nWith regard to cyberbullying, a number of national and international initiatives have been launched over the past few years to increase children's online safety. Examples include KiVa, a Finnish cyberbullying prevention programme, the `Non au harcèlement' campaign in France, Belgian governmental initiatives and helplines (e.g. clicksafe.be, veiligonline.be, mediawijs.be) that provide information about online safety, and so on.\nIn spite of these efforts, a lot of undesirable and hurtful content remains online. BIBREF1 analysed a body of quantitative research on cyberbullying and observed cybervictimisation rates among teenagers between 20% and 40%. BIBREF5 focused on 12 to 17 year olds living in the United States and found that no less than 72% of them had encountered cyberbullying at least once within the year preceding the questionnaire. BIBREF6 surveyed 9 to 26 year olds in the United States, Canada, the United Kingdom and Australia, and found that 29% of the respondents had ever been victimised online. A study among 2,000 Flemish secondary school students (age 12 to 18) revealed that 11% of them had been bullied online at least once in the six months preceding the survey BIBREF7 . Finally, the 2014 large-scale EU Kids Online Report BIBREF8 published that 20% of 11 to 16 year olds had been exposed to hate messages online. In addition, youngsters were 12% more likely to be exposed to cyberbullying as compared to 2010, clearly demonstrating that cyberbullying is a growing problem.\nThe prevalence of cybervictimisation depends on the conceptualisation used in describing cyberbullying, but also on research variables such as location and the number and age span of its participants. Nevertheless, the above-mentioned studies demonstrate that online platforms are increasingly used for bullying, which is a cause for concern given its impact. As shown by BIBREF9 , BIBREF10 , BIBREF11 , cyberbullying can have a negative impact on the victim's self-esteem, academic achievement and emotional well-being. BIBREF12 found that self-reported effects of cyberbullying include negative effects on school grades, feelings like sadness, anger, fear, and depression and in extreme cases, cyberbullying could even lead to self-harm and suicidal thoughts.\nThe above studies demonstrate that cyberbullying is a serious problem the consequences of which can be dramatic. Successful early detection of cyberbullying attempts is therefore of key importance to youngsters' mental well-being. However, the amount of information on the Web makes it practically unfeasible for moderators to monitor all user-generated content manually. To tackle this problem, intelligent systems are required that process this information in a fast way and automatically signal potential threats. This way, moderators can respond quickly and prevent threatening situations from escalating. According to recent research, teenagers are generally in favour of such automatic monitoring, provided that effective follow-up strategies are formulated, and that privacy and autonomy are guaranteed BIBREF13 .\nParental control tools (e.g. NetNanny) already block unsuited or undesirable content and some social networks make use of keyword-based moderation tools (i.e., using lists of profane and insulting words to flag harmful content). However, such approaches typically fail to detect implicit or subtle forms of cyberbullying in which no explicit vocabulary is used. There is therefore a need for intelligent and self-learning systems that can go beyond keyword spotting and hence improve recall of cyberbullying detection.\nThe ultimate goal of this sort of research is to develop models which could improve manual monitoring for cyberbullying on social networks. We explore the automatic detection of textual signals of cyberbullying, in which it is approached as a complex phenomenon that can be realised in various ways (see Section SECREF15 for a detailed overview). While a lot of the related research focuses on the detection of cyberbullying `attacks', the present study takes into account a broader range of textual signals of cyberbullying, including posts written by bullies, as well as by victims and bystanders.\nWe propose a machine learning method to cyberbullying detection by making use of a linear SVM classifier BIBREF14 , BIBREF15 exploiting a varied set of features. To the best of our knowledge, this is the first approach to the annotation of fine-grained text categories related to cyberbullying and the detection of signals of cyberbullying events. It is also the first elaborate research on automatic cyberbullying detection on Dutch social media. For the present experiments, we focus on an English and Dutch ASKfm corpus, but the methodology adopted is language and genre independent, provided there is annotated data available.\nThe remainder of this paper is structured as follows: the next section presents a theoretic overview and gives an overview of the state of the art in cyberbullying detection, whereas Section SECREF3 describes the corpus. Next, we present the experimental setup and discuss our experimental results. Finally, Section SECREF6 concludes this paper and provides perspectives for further research.\nHowever, the amount of information on the Web makes it practically unfeasible for moderators to monitor all user-generated content manually.",

We then cluster these vector representations for each model using a Gaussian Mixture Model (GMM) with $k$ pre-defined clusters. We chose GMM as our clustering approach as it allows soft assignments (vs. hard assignments as in e.g. K-means) which we think fits the task better (as a sentence can be seen as drawn from a mixture of several domain). In all cases, to create a sentence representation we perform average pooling of the last hidden state (before the softmax layer) for each token in the sentence. To accelerate the clustering process and enable visualization we also experiment with performing dimensionality reduction with PCA over the sentence vectors before clustering them. We experiment with k in 5, 10 and 15 to test how adding flexibility would improve the domain clustering accuracy.\nWe propose two methods for domain data selection with pretrained language models.\nDomain-Cosine In this method we first compute a query vector, which is the element-wise average over the vector representations of the sentences in the small in-domain set. We use the same sentence-level average-pooling approach as described in Section SECREF2 to obtain sentence representations. We then retrieve the most relevant sentences in the training set by computing the cosine similarity of each sentence with this query vector and ranking the sentences accordingly.\nDomain-Finetune It is now common knowledge that pretrained language models are especially useful when fine-tuned for the task of interest in an end-to-end manner BIBREF41. In this method we fine-tune the pretrained LM for binary classification, where we use the in-domain sentences as positive examples, and randomly sampled general-domain sentences as negative examples. We then apply this classifier on the general-domain data and pick the sentences that are classified as positive as in-domain, or choose the top-k sentences as ranked by the classifier output distribution. This can be seen as an instance of positive-unlabeled learning for document-set expansion; see BIBREF42 for a recent discussion and methodology for this task.\nNegative Sampling with Pre-ranking One problem that may rise when randomly sampling negative examples is that unlabeled in-domain sentences from the general-domain data may be sampled as negative examples – deteriorating the classifier performance. To alleviate this issue, we perform a biased sampling of negative examples. We first rank the general-domain data using the Domain-Cosine method, and then sample negative examples under a certain threshold in the ranking (in our experiments we sampled from the bottom two-thirds). Table TABREF31 shows an ablation for such pre-ranking, measuring precision, recall and F1 for binary classification on a held-out set for each domain. When not using pre-ranking, as the training data for the domain is larger, the precision is lower – since more in-domain examples are drawn as negative samples. Using pre-ranking indeed alleviates this issue, achieving higher F1 scores in all cases. Given the results in Table TABREF31 we always use pre-ranking in the following experiments.\nThe first is using representations from word2vec,where we average-pooled the word vectors for the tokens that were present in the model vocabulary.The second is using Latent Dirichlet Allocation, which is a classic approach to unsupervised clustering of text.",

In traditional superconducting solenoids, liquid helium is used to cool the inner coils because it has a boiling point of around 4 K at ambient pressure. Cheap metallic superconductors can be used for the coil wiring. So-called high-temperature superconducting compounds can be made to super conduct with the use of liquid nitrogen, which boils at around 77 K.\nMagnetic resonance imaging (MRI) is a complex application of NMR where the geometry of the resonances is deconvoluted and used to image objects by detecting the relaxation of protons that have been perturbed by a radio-frequency pulse in the strong magnetic field. This is most commonly used in health applications.\nIn large cities, it is difficult to transmit power by overhead cables, so underground cables are used. But underground cables get heated and the resistance of the wire increases, leading to waste of power.

        "evidence": "Understanding what a question is asking is one of the first steps that humans use to work towards an answer. In the context of question answering, question classification allows automated systems to intelligently target their inference systems to domain-specific solvers capable of addressing specific kinds of questions and problem solving methods with high confidence and answer accuracy BIBREF0 , BIBREF1 .\nTo date, question classification has primarily been studied in the context of open-domain TREC questions BIBREF2 , with smaller recent datasets available in the biomedical BIBREF3 , BIBREF4 and education BIBREF5 domains. The open-domain TREC question corpus is a set of 5,952 short factoid questions paired with a taxonomy developed by Li and Roth BIBREF6 that includes 6 coarse answer types (such as entities, locations, and numbers), and 50 fine-grained types (e.g. specific kinds of entities, such as animals or vehicles). While a wide variety of syntactic, semantic, and other features and classification methods have been applied to this task, culminating in near-perfect classification performance BIBREF7 , recent work has demonstrated that QC methods developed on TREC questions generally fail to transfer to datasets with more complex questions such as those in the biomedical domain BIBREF3 , likely due in part to the simplicity and syntactic regularity of the questions, and the ability for simpler term-frequency models to achieve near-ceiling performance BIBREF8 . In this work we explore question classification in the context of multiple choice science exams. Standardized science exams have been proposed as a challenge task for question answering BIBREF9 , as most questions contain a variety of challenging inference problems BIBREF10 , BIBREF11 , require detailed scientific and common-sense knowledge to answer and explain the reasoning behind those answers BIBREF12 , and questions are often embedded in complex examples or other distractors. Question classification taxonomies and annotation are difficult and expensive to generate, and because of the unavailability of this data, to date most models for science questions use one or a small number of generic solvers that perform little or no question decomposition BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 . Our long-term interest is in developing methods that intelligently target their inferences to generate both correct answers and compelling human-readable explanations for the reasoning behind those answers. The lack of targeted solving – using the same methods for inferring answers to spatial questions about planetary motion, chemical questions about photosynthesis, and electrical questions about circuit continuity – is a substantial barrier to increasing performance (see Figure FIGREF1 ).\nTo address this need for developing methods of targetted inference, this work makes the following contributions:\nIn the context of question answering, question classification allows automated systems to intelligently target their inference systems to domain-specific solvers capable of addressing specific kinds of questions and problem solving methods with high confidence and answer accuracy (Hovy et al., 2001; Moldovan et al., 2003).",

While suitable for analysis, the small size of the test suites makes it hard to make statistically confident comparisons between systems, and the hand-picked nature of the test suites introduces biases. To overcome these problems, we opted for a fully automatic approach to constructing a large-scale test suite.\nConceptually, our test set is most similar to the “cross-lingual pronoun prediction” task held at DiscoMT and WMT in recent years BIBREF15 , BIBREF16 , BIBREF17 : participants are asked to fill a gap in a target sentence, where gaps correspond to pronouns.\nThe first edition of the task focused on English INLINEFORM0 French, and it was found that local context (such as the verb group) was a strong signal for pronoun prediction. Hence, future editions only provided target-side lemmas instead of fully inflected forms, which makes the task less suitable to evaluate end-to-end neural machine translation systems, although such systems have been trained on the task BIBREF18 .\n BIBREF17 do not report on the proportion of intra-sentential and inter-sentential anaphora in their test set, but the two top-performing systems only made use of intra-sentential information. Our test suite focuses on allowing the comparison of end-to-end context-aware NMT systems, and we thus extract a large number of inter-sentential anaphora, with meta-data allowing for a focus on inter-sentential anaphora with a long distance between the pronoun and its antecedent. Our focus on evaluating end-to-end NMT systems also relieves us from having to provide annotated training sets, and reduces pressure to achieve balance and full coverage of phenomena.\nAn alternative approach to automatically evaluate pronoun translation are reference-based methods that produce a score based on word alignment between source, translation output, and reference translation, and identification of pronouns in them, such as AutoPRF BIBREF19 and APT BIBREF20 . BIBREF21 perform a human meta-evaluation and show substantial disagreement between reference-based metrics and human judges, especially because there often exist valid alternative translations that use different pronouns than the reference. Our test set, and our protocol of generating contrastive examples, is focused on selected pronouns to minimize the risk of producing contrastive examples that are actually valid translations.\nThe first edition of the task focused on English→French, and it was found that local context (such as the verb group) was a strong signal for pronoun prediction.",

        "answer": "The authors use word order permutations to control for unigram and positional statistics.",
        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nWe use word order permutations to control for unigram and positional statistics.",

While NMT is generally more fluent than previous statistical systems, adequacy is still a major concern BIBREF4 : common mistakes include dropping source words and repeating words in the generated translation.\nPrevious work has attempted to mitigate this problem in various ways. BIBREF5 incorporate coverage and length penalties during beam search—a simple yet limited solution, since it only affects the scores of translation hypotheses that are already in the beam. Other approaches involve architectural changes: providing coverage vectors to track the attention history BIBREF6 , BIBREF7 , using gating architectures and adaptive attention to control the amount of source context provided BIBREF8 , BIBREF9 , or adding a reconstruction loss BIBREF10 . BIBREF11 also use the notion of fertility implicitly in their proposed model. Their “fertility conditioned decoder” uses a coverage vector and an “extract gate” which are incorporated in the decoding recurrent unit, increasing the number of parameters.\nIn this paper, we propose a different solution that does not change the overall architecture, but only the attention transformation. Namely, we replace the traditional softmax by other recently proposed transformations that either promote attention sparsity BIBREF12 or upper bound the amount of attention a word can receive BIBREF13 . The bounds are determined by the fertility values of the source words. While these transformations have given encouraging results in various NLP problems, they have never been applied to NMT, to the best of our knowledge. Furthermore, we combine these two ideas and propose a novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments. While being in-between soft and hard alignments (Figure FIGREF20 ), the constrained sparsemax transformation is end-to-end differentiable, hence amenable for training with gradient backpropagation.\nTo sum up, our contributions are as follows:\nThe bounds are determined by the fertility values of the source words.",

Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process.",

        "evidence": "In an economic model, agents have a comparative advantage over others in producing a particular good if they can produce that good at a lower relative opportunity cost or autarky price, i.e. at a lower relative marginal cost prior to trade. Comparative advantage describes the economic reality of the work gains from trade for individuals, firms, or nations, which arise from differences in their factor endowments or technological progress. (The absolute advantage, comparing output per time (labor efficiency) or per quantity of input material (monetary efficiency), is generally considered more intuitive, but less accurate — as long as the opportunity costs of producing goods across countries vary, productive trade is possible.)\n\nDavid Ricardo developed the classical theory of comparative advantage in 1817 to explain why countries engage in international trade even when one country's workers are more efficient at producing every single good than workers in other countries. He demonstrated that if two countries capable of producing two commodities engage in the free market (albeit with the assumption that the capital and labour do not move internationally), then each country will increase its overall consumption by exporting the good for which it has a comparative advantage while importing the other good, provided that there exist differences in labor productivity between both countries. Widely regarded as one of the most powerful yet counter-intuitive insights in economics, Ricardo's theory implies that comparative advantage rather than absolute advantage is responsible for much of international trade.",

Near Earth's surface, the gravity acceleration is approximately 9.81 m/s2 (32.2 ft/s2), which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres (32.2 ft) per second every second. This quantity is sometimes referred to informally as little g (in contrast, the gravitational constant G is referred to as big G).\n\nThe precise strength of Earth's gravity varies depending on the location. The nominal \"average\" value at Earth's surface, known as standard gravity is, by definition, 9.80665 m/s2 (32.1740 ft/s2). This quantity is denoted variously as gn, ge (though this sometimes means the normal equatorial value on Earth, 9.78033 m/s2 (32.0877 ft/s2)), g0, gee, or simply g (which is also used for the variable local value).\n\nThe weight of an object on Earth's surface is the downwards force on that object, given by Newton's second law of motion, or F = m a (force = mass × acceleration). Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object.

Hence, this definition is not adequate for our purposes, since it does not include the racist utterances one would find on social media; few utterances that people might perceive as racist are actually punishable by law, as only utterances which explicitly encourage the use of violence are illegal. For this reason, we use a common sense definition of racist language, including all negative utterances, negative generalizations and insults concerning ethnicity, nationality, religion and culture. In this, we follow paolo2015racist, bonilla2002linguistics and razavi2010offensive, who show that racism is no longer strictly limited to physical or ethnic qualities, but can also include social and cultural aspects.\nwe use a common sense definition of racist language, including all negative utterances, negative generalizations and insults concerning ethnicity, nationality, religion and culture.",

        "question": "Why is MPPT necessary?",
        "evidence": "Maximum power point tracking (MPPT) or sometimes just power point tracking (PPT), is a technique used with variable power sources to maximize energy extraction as conditions vary. The technique is most commonly used with photovoltaic (PV) solar systems, but can also be used with wind turbines, optical power transmission and thermophotovoltaics.\n\nPV solar systems have varying relationships to inverter systems, external grids, battery banks, and other electrical loads. The central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on the amount of available sunlight, shading, solar panel temperature and the load's electrical characteristics. As these conditions vary, the load characteristic (impedance) that gives the highest power transfer changes. The system is optimized when the load characteristic changes to keep power transfer at highest efficiency. This optimal load characteristic is called the maximum power point (MPP). MPPT is the process of adjusting the load characteristic as the conditions change. Circuits can be designed to present optimal loads to the photovoltaic cells and then convert the voltage, current, or frequency to suit other devices or systems.\n\nSolar cells' non-linear relationship between temperature and total resistance can be analyzed based on the Current-voltage (I-V) curve and the power-voltage (P-V) curves. MPPT samples cell output and applies the proper resistance (load) to obtain maximum power. MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors. Solar inverters convert DC power to AC power and may incorporate MPPT.\n\nThe power at the MPP (Pmpp) is the product of the MPP voltage (Vmpp) and MPP current (Impp).\n\nIn general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the curve.",
        "answer": "The efficiency of transferring the power from the photovoltaic (PV) solar systems depends on many factors which change frequently.

However, the warming and drying climate meant that by 5000 BCE, the Sahara region was becoming increasingly dry and hostile. Around 3500 BCE, due to a tilt in the earth's orbit, the Sahara experienced a period of rapid desertification. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements.

It was released in 2011 for Microsoft Windows, then ported to OS X, and Linux. The game's title and plot are inspired by the Biblical story of the Binding of Isaac. In the game, Isaac's mother receives a message from God demanding the life of her son as proof of her faith, and Isaac, fearing for his life, flees into the monster-filled basement of their home where he must fight to survive. Players control Isaac or one of seven other unlockable characters through a procedurally generated dungeon in a roguelike manner, fashioned after those of The Legend of Zelda, defeating monsters in real-time combat while collecting items and power-ups to defeat bosses and eventually Isaac's mother.\n\nThe game was the result of a week-long game jam between McMillen and Himsl to develop a The Legend of Zelda-inspired roguelike that allowed McMillen to showcase his feelings about both positive and negative aspects of religion that he had come to discover from conflicts between his Catholic and born again Christian family members while growing up. McMillen had considered the title a risk but one he could take after the financial success of Super Meat Boy, and released it without much fanfare to Steam in September 2011, not expecting many sales. The game soon gained popularity partially as a result of various Let's Play videos showcasing the title. McMillen and Himsl released an expansion \"Wrath of the Lamb\" in May 2012, but were limited from further expansion due to limitations with the Flash platform. They had started working with Nintendo in 2012 to release a 3DS version, but Nintendo later backed out of the deal, citing controversy over the game's religious themes.\n\nDeveloper Nicalis worked with McMillen in 2014 to complete a remake of the game, The Binding of Isaac: Rebirth, bringing additional features that McMillen had planned that exceeded Flash's limitation, as well as to improve the game's graphics and enable ports for other systems beyond personal computers, including PlayStation 4 and Vita, Xbox One, Wii U, Nintendo 3DS, and the Nintendo Switch. This remake has commonly been cited as one of the best roguelike games of all time.\n\nMcMillen later worked with James Id to develop The Legend of Bum-bo, which serves as a prequel to The Binding of Isaac.\n\nThe Binding of Isaac has been well-received, with critics praising the game's roguelike nature to encourage repeated playthroughs. By July 2014, McMillen reported over 3 million copies had been sold. The game has been said to contribute to renewed interest in the roguelike genre from both players and developers.",

Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nIn the first architecture, we use LSTM (Hochreiter and Schmidhuber, 1997) for a sequential input of the words within the sentences of the transcripts.",

This philosophy was exemplified in Fallingwater (1935), which has been called \"the best all-time work of American architecture\".\n\nWright was the pioneer of what came to be called the Prairie School movement of architecture and also developed the concept of the Usonian home in Broadacre City, his vision for urban planning in the United States. He also designed original and innovative offices, churches, schools, skyscrapers, hotels, museums, and other commercial projects.

        "question": "Through their observation, which model's loss decays is faster?",
        "answer": "The Pre-LN Transformer model.",
        "evidence": "The Transformer BIBREF0 is one of the most commonly used neural network architectures in natural language processing. Layer normalization BIBREF1 plays a key role in Transformer's success. The originally designed Transformer places the layer normalization between the residual blocks, which is usually referred to as the Transformer with Post-Layer Normalization (Post-LN) BIBREF2. This architecture has achieved state-of-the-art performance in many tasks including language modeling BIBREF3, BIBREF4 and machine translation BIBREF5, BIBREF6. Unsupervised pre-trained models based on the Post-LN Transformer architecture also show impressive performance in many downstream tasks BIBREF7, BIBREF8, BIBREF9.\nDespite its great success, people usually need to deal with the optimization of the Post-LN Transformer more carefully than convolutional networks or other sequence-to-sequence models BIBREF10. In particular, to train the model from scratch, any gradient-based optimization approach requires a learning rate warm-up stage BIBREF0, BIBREF11: the optimization starts with an extremely small learning rate, and then gradually increases it to a pre-defined maximum value in a pre-defined number of iterations. Such a warm-up stage not only slows down the optimization process but also brings more hyperparameter tunings. BIBREF10 has shown that the final model performance is quite sensitive to the value of the maximum learning rate and the number of warm-up iterations. Tuning such sensitive hyper-parameters is costly in training large-scale models, e.g., BERT BIBREF8 or XLNet BIBREF9.\nIn this paper, we try to alleviate this problem by finding ways to safely remove the learning rate warm-up stage. As the warm-up stage happens in the first several iterations, we investigate the optimization behavior at initialization using mean field theory BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. According to our theoretical analysis, when putting the layer normalization between the residual blocks, the expected gradients of the parameters near the output layer are large. Therefore, without the warm-up stage, directly using a large learning rate to those parameters can make the optimization process unstable. Using a warm-up stage and training the model with small learning rates practically avoid this problem. Extensive experiments are provided to support our theoretical findings.\nOur theory also shows that the layer normalization plays a crucial role in controlling the gradient scales. This motivates us to investigate whether there are some other ways of positioning the layer normalization that lead to well-behaved gradients. In particular, we study another variant, the Transformer with Pre-Layer Normalization (Pre-LN) BIBREF18, BIBREF19, BIBREF2. The Pre-LN Transformer puts the layer normalization inside the residual connection and equips with an additional final-layer normalization before prediction (Please see Figure SECREF1 for the differences between the two variants of the Transformer architectures). We show that at initialization, the gradients are well-behaved without any exploding or vanishing for the Pre-LN Transformer both theoretically and empirically.\nGiven the gradients are well-behaved in the Pre-LN Transformer, it is natural to consider removing the learning rate warm-up stage during training. We conduct a variety of experiments, including IWSLT14 German-English translation, WMT14 English-German translation, and BERT pre-training tasks. We show that, in all tasks, the learning rate warm-up stage can be safely removed, and thus, the number of hyper-parameter is reduced. Furthermore, we observe that the loss decays faster for the Pre-LN Transformer model. It can achieve comparable final performances but use much less training time. This is particularly important for training large-scale models on large-scale datasets.\nOur contributions are summarized as follows:\n$\\bullet $ We investigate two Transformer variants, the Post-LN Transformer and the Pre-LN Transformer, using mean field theory. By studying the gradients at initialization, we provide evidence to show why the learning rate warm-up stage is essential in training the Post-LN Transformer.\n$\\bullet $ We are the first to show that the learning-rate warm-up stage can be removed for the Pre-LN Transformer, which eases the hyperparameter tuning. We further show that by using proper learning rate schedulers, the training time can be largely reduced on a wide range of applications.\nFurthermore, we observe that the loss decays faster for the Pre-LN Transformer model.",

Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.",

How to achieve this goal? If LIP cannot embed into current DIP related works like this, it is useless in practice.",
        "answer": "We respectfully disagree. The found LIP subnetworks by multi-image based IMP are practical because they have the powerful transferability: 1) They can transfer across different images (Figure 5 illustrates this point); 2) They can successfully transfer across different restoration tasks such as denoising, inpainting and super-resolution (Figure 7 illustrates this point). And therefore, there is no need to do the IMP process again and again for obtaining desired LIPs in different tasks. We hope the reviewer will capture this crucial point and give a more fair assessment, instead of rushing to an ungrounded accusation of “useless”.",
        "evidence": "Background Deep neural networks (DNNs), in particular convolutional neural networks (CNNs), have been powerful tools for solving various image inverse problems such as denoising, inpainting, and super resolution. Conventional wisdom believes that is owing to DNNs' universal approximation ability and learning from massive training data. Yet, recent studies have revealed the specific architectures of CNNs have the inductive bias to represent and generate natural images well, and such favorable architecture inductive bias can work independently from fitting specific training sets.\nFor example, deep image prior (DIP) shows an untrained neural network can be used as a handcrafted prior that transfers well across multiple inverse problems. The authors attributed the success to the CNN architecture itself, that appeared to possess high noise impedance even with only random initializations. As another example, in compressive sensing,; replaced the common structural assumptions such as sparsity with a pretrained generative adversarial networks. The underlying rationale lies in that a pre-trained generator should (approximately) represent the notion of a vector being or more likely in the target domain such as natural images; in other words, a sample more like a natural image will be closer to the output range of the pre-trained generator. In this paper, we refer to such general-purpose image prior parameterized by (either untrained or pre-trained) DNNs as DNN-based image priors.\nRecall that, classical image regularizers in the spatial or frequency domains are often not learningbased, or rely on compact learning models. On contrary, DNN-based image priors have a massive number of parameters (we compare the parameter numbers between the full model and the sparse subnetwork in Table 2), typically magnitudes more than the image (even the image size) size. The two extremes invite the natural question: Can we identify highly compact DNN-based image priors, that are same effective? We note that, diving into this question has twofold appeals. On the algorithmic side, that could help us understand further how the topology and connectivity of CNN architecture itself will affect the effectiveness of those priors, and to what extent sparsity could be relevant. On the practical side, if we could provide an affirmative answer to this question, that would potentially lead to more computationally savings when applying those DNN-based priors in practice, leading to faster restoration or computational imaging with them.\nTowards the above question, the tool we refer to in this paper is the recently emerged Lottery Ticket Hypothesis (LTH). LTH suggests that every dense DNN has an extremely sparse \"matching subnetwork\", that can be trained in isolation to match the original dense DNN's accuracy. While the vanilla LTH studies training from random scratch, the latest works also extend similar findings to fine-tuning the pre-trained models. LTH has widespread success in image classification, language modeling, reinforcement learning and multi-modal learning, e.g.,.\nOur Contributions Drawing inspirations from the LTH literature, we conjecture and empirically study a novel \"lottery image prior\" (LIP), stated as: Given an (untrained or trained) DNN-based image prior, it will have a sparse subnetwork that can be trained in isolation, to match the original DNN's performance when being applied as a prior to regularizing various image inverse problems.\nStudying this new problem is, however, NOT a naive extension from the existing LTH methods, owing to several technical barriers: (a) till now, LTH has not been demonstrated for image inverse problem or DNN-based priors, to our best knowledge. Most LTH works studied discriminative tasks, with one exception. It is therefore uncertain whether high-sparsity DNN is still viable for reconstruction-oriented tasks; (b) existing LTH works typically require a full training set to locate the sparse subnetwork mask, whereas our LIP settings are only not data-rich. For example, DIP needs the DNN to be trained to overfit one specific image, making it drastically different from previous problems; (c) the objectives between finding the sparse mask (e.g., learning the prior) and fitting the sparse subnetwork (e.g., using the prior) are often unaligned in LIP problems. For example, DIP will overfit a corrupted input image (during which the sparse mask will be found) in order to reconstruct a clean output image (when the found sparse subnetwork will be used); the pre-trained generator will also be used towards a different goal (regularizing compressive sensing) from their original pre-training task (generating realistic images).\nOur extensive experimental study confirms the existence of LIP in two representative settings: (i) image restoration with the deep image prior, using an untrained DNN (as shown in Fig.); and\n(ii) compressive sensing image reconstruction, using a pre-trained GAN generator. Using iterative magnitude pruning (IMP) with surrogate tasks (the overview of our work paradigm is in Fig.), we can successfully locate the LIP subnetworks at the sparsity range of 20%-86.58% in setting i; and those at the sparsity range of 5%-36% in setting ii. Those LIP subnetworks also possess high transferability. For example, the LIP ticket found in the setting i transfer well across not only different images, but also different tasks such as denoising, inpainting and super-resolution. Our contributions are summarized below:\n• The first comprehensive study on LTH in DNN-based image priors and inverse problems, establishing the \"lottery image prior\" (LIP) and demonstrating the prevailing relevance of LTH more broadly than previously typical settings. The last column (in blue) intends to display the results with the most extremely sparse subnetwork.\n• The investigation of both untrained and pre-trained DNNs as image priors, verifying that LIP subnetworks can be found in both settings, by overcoming several impediments such as severely limited training data and task objective mismatch. • High transferability of LIP subnetworks across data/datasets, and various inverse problem tasks. Our finding reflects the underlying common image prior that is agnostic to specific data or task, through the lens of the CNN architecture together with sparsity.\nIn this section, we will investigate the lottery image prior (LIP) property under setting i, for deep image prior (DIP) models. Model performance is measured by PSNR (Peak Signal to Noise Ratio) between the restored images and the clean ground truths (SSIM (Structural Similarity) results are in supplementary materials). We run all experiments with three different random seeds. All images used for plotting results are summarized in Fig..\nIn DIP, for each degraded image to be restored, an untrained DNN will be over-fitted over that single image (with proper early stopping). This casts a crucial difference from typical LTH settings where winning tickets are identified using IMP over a distribution of data and are verified to be effective when trained on data from that specific distribution. Therefore, besides the usual properties in winning tickets such as the existence, the superiority over other pruning methods, and the effect of rewinding, we will strive to answer two more questions about LIP in DIP. The first question is: can we extend the IMP algorithm for single-image DIP to multi-image and thus improve the performance of winning tickets hopefully? The second question is to what extend the LIP found in DIP setting can be transferred? Answering these two questions not only provides a clearer picture of LIP, but also hints a new perspective for a deeper understanding of LTH.\nIn DIP setting, we first find the winning tickets with LIP property by implementing the single-image IMP on the hourglass model (i.e., the DIP model used in. We adopt the modified objectives using clean images as labels as we discussed in Sec. 3.2. The algorithm is described in detail in Algorithm 1. We apply the implemented algorithm on Set5  ( and Set14 datasets to obtain the sparse subnetworks 1 and evaluate these subnetworks on the denoising task.\nResults of single-image IMP in Fig. (curves in red colors) verify that the LIP exists in the DIP setting. To be specific, during the IMP finding process when we use clean images in DIP objectives, we are able to find the winning tickets with LIP on untrained DNN at sparsity as high as 86.58%. While at the evaluation stage, when we only have access to the degraded images, we find that the winning tickets found with the modified objectives are still applicable, matching the dense performance at sparsity as high as 83.23%.\nBesides the dense model baselines, we also compare the single-image IMP with Random Pruning, and a pruning-at-initialization method SNIP, whose results are also presented in Fig. in other colors. Specifically, we clearly observe from the first row in Fig. that the singleimage IMP for DIP outperforms random pruning and SNIP at a wide sparsity range [20%, 96%]. Interestingly, we find random prune is a good competitor to SNIP sometimes, but both of them suffer significant performance decrease at extreme sparsities (over 80%), where IMP still persists.\nThe Effect of Weight Rewinding In this part, we study the effect of weight rewinding Is Multi-image IMP A Good Extension in DIP? DIP over-fits an untrained DNN on a single image. A reasonable conjecture is that the DNN will be dedicated to the features in that specific image and so should the resulting winning ticket be if we apply single-image IMP to the DIP model. We then ask that whether we can co-consider multiple images during IMP for DIP models to find winning tickets that are suitable for more general features and thus yield better image restoration performance? To verify our idea, we propose a new multi-image IMP for DIP where we replace the single-image DIP objective with the average of multiple images during the IMP process. Note that all images will share the same fixed random code during IMP. Otherwise, different random codes will intervene with one another because they lead to different winning tickets, resulting in a share subnetwork with inferior performance. The algorithm is formally described in Algorithm 2.\nWe evaluate the multi-image IMP in two different settings: (i) cross-domain setting where we apply the multi-image IMP to the five images from Set5; (2) single-domain setting where we apply the multi-image IMP to five images of human faces with glasses. We think images from Set 5 are from more diversified domains because they include bird, butterfly and human face contents. We compare single-image IMP winning tickets found on the Baby and the Woman images from Set5 with the cross-domain ticket, and the single-image IMP winning tickets found on Face-1 and Face-2 with the single-domain ticket. Results presented in Fig. show that multi-image IMP significantly improves the quality of the winning tickets in the cross-domain setting, which is aligned with our previous hypothesis.\nTo what extent can LIP tickets be transferred? Transferability is an important metric to measure the usefulness of LIP in the DIP setting. It would significantly undermine the practical application of LIP if the winning tickets can only be dedicatedly found for each image. In this part, we evaluate the transferability of LIP for DIP models from three perspectives, i.e., the transferability between images, between image restoration tasks and between high-level tasks.\nObservation 1: LIP can transfer across images. We identify the single-image LIPs for all image from Set5 and the multi-image LIP on Set5 using the new multi-image IMP proposed in the last part. Then we evaluate all the above LIPs on the Baby image, results being presented in Fig.. We can see that the LIPs found on other images, even those from the Bird and the Butterfly images, can perform comparably well with LIP dedicatedly found on the Baby image. This shows that LIP has reasonable transferability across images, even for those coming from slightly different domains (for example, the Baby and the Butterfly). We can also observe the fact that the multi-image LIP outperforms all single-image LIPs, as side support for the superiority of multi-image LIP in the cross-domain settings.\nObservation 2: LIP can transfer across image restoration tasks but not to other high-level tasks.  We test the denoising LIP on MNIST and CIFAR10 datasets (left 2 figures). Note that we replace the last convolutional layer of DIP models with the linear layer and load the same initial weights. We evaluate the CIFAR LIP on the denoising task.\ninterests? Furthermore, if the above question has an affirmative answer, is such transferability sustainable when transferring to or from some high-level tasks such as classification?\nTo evaluate the transferability of LIP between image restoration tasks, we first find three LIPs for the denoising, inpainting and super-resolution tasks respectively and then transfer between them, as shown in Fig.. We observe that a LIP winning ticket transferred from another image restoration task always yields restoration performance comparable with the single-image LIP found on the original task, sometimes even better, for examples in Fig.(a) and 7(g).\nWe then evaluate the transferability of LIP between the denoising task and image classification task on CIFAR-10. We apply the standard IMP on the DIP model, i.e., the hourglass architecture in, to obtain winning tickets on MNIST and CIFAR-10 datasets. We show the results of transferring the denoising LIP to MNIST in Fig.(a) and CIFAR-10 in 8(b) and the CIFAR-10 winning tickets to denoising task in Fig.). Although transferring denoising LIP to MNIST seems to yield winning tickets due to MNIST's low complexity, its transfer to CIFAR-10 is unsuccessful. Interestingly, the multi-image LIP becomes a worse ticket on CIFAR-10 than the single-image LIP. Moreover, transferring winning tickets on CIFAR-10 back to the denoising DIP task also fails to generate winning tickets that are comparable with denoising LIPs.\nBased on those observations, we conjecture that the architecture priors needed to \"win the lottery ticket\" may substantially differ between low-level (reconstruction, restoration,...) and high-level (classification, recognition,...) vision tasks, but seems to be quite overlapped/shareable among different tasks that are all low-level (or high-level). The high-level task transferability of winning tickets has been found in prior works. We believe this interesting \"incompatibility\" between low-level and high-level tasks is an unstudied new direction, and leave this for our future work.\nBackground Deep neural networks (DNNs), in particular convolutional neural networks (CNNs), have been powerful tools for solving various image inverse problems such as denoising, inpainting, and super resolution. Conventional wisdom believes that is owing to DNNs' universal approximation ability and learning from massive training data. Yet, recent studies have revealed the specific architectures of CNNs have the inductive bias to represent and generate natural images well, and such favorable architecture inductive bias can work independently from fitting specific training sets.\nFor example, deep image prior (DIP) shows an untrained neural network can be used as a handcrafted prior that transfers well across multiple inverse problems. The authors attributed the success to the CNN architecture itself, that appeared to possess high noise impedance even with only random initializations. As another example, in compressive sensing,; replaced the common structural assumptions such as sparsity with a pretrained generative adversarial networks. The underlying rationale lies in that a pre-trained generator should (approximately) represent the notion of a vector being or more likely in the target domain such as natural images; in other words, a sample more like a natural image will be closer to the output range of the pre-trained generator. In this paper, we refer to such general-purpose image prior parameterized by (either untrained or pre-trained) DNNs as DNN-based image priors.\nRecall that, classical image regularizers in the spatial or frequency domains are often not learningbased, or rely on compact learning models. On contrary, DNN-based image priors have a massive number of parameters (we compare the parameter numbers between the full model and the sparse subnetwork in Table 2), typically magnitudes more than the image (even the image size) size. The two extremes invite the natural question: Can we identify highly compact DNN-based image priors, that are same effective? We note that, diving into this question has twofold appeals. On the algorithmic side, that could help us understand further how the topology and connectivity of CNN architecture itself will affect the effectiveness of those priors, and to what extent sparsity could be relevant. On the practical side, if we could provide an affirmative answer to this question, that would potentially lead to more computationally savings when applying those DNN-based priors in practice, leading to faster restoration or computational imaging with them.\nTowards the above question, the tool we refer to in this paper is the recently emerged Lottery Ticket Hypothesis (LTH). LTH suggests that every dense DNN has an extremely sparse \"matching subnetwork\", that can be trained in isolation to match the original dense DNN's accuracy. While the vanilla LTH studies training from random scratch, the latest works also extend similar findings to fine-tuning the pre-trained models. LTH has widespread success in image classification, language modeling, reinforcement learning and multi-modal learning, e.g.,.\nOur Contributions Drawing inspirations from the LTH literature, we conjecture and empirically study a novel \"lottery image prior\" (LIP), stated as: Given an (untrained or trained) DNN-based image prior, it will have a sparse subnetwork that can be trained in isolation, to match the original DNN's performance when being applied as a prior to regularizing various image inverse problems.\nStudying this new problem is, however, NOT a naive extension from the existing LTH methods, owing to several technical barriers: (a) till now, LTH has not been demonstrated for image inverse problem or DNN-based priors, to our best knowledge. Most LTH works studied discriminative tasks, with one exception. It is therefore uncertain whether high-sparsity DNN is still viable for reconstruction-oriented tasks; (b) existing LTH works typically require a full training set to locate the sparse subnetwork mask, whereas our LIP settings are only not data-rich. For example, DIP needs the DNN to be trained to overfit one specific image, making it drastically different from previous problems; (c) the objectives between finding the sparse mask (e.g., learning the prior) and fitting the sparse subnetwork (e.g., using the prior) are often unaligned in LIP problems. For example, DIP will overfit a corrupted input image (during which the sparse mask will be found) in order to reconstruct a clean output image (when the found sparse subnetwork will be used); the pre-trained generator will also be used towards a different goal (regularizing compressive sensing) from their original pre-training task (generating realistic images).\nOur extensive experimental study confirms the existence of LIP in two representative settings: (i) image restoration with the deep image prior, using an untrained DNN (as shown in Fig.); and\n(ii) compressive sensing image reconstruction, using a pre-trained GAN generator. Using iterative magnitude pruning (IMP) with surrogate tasks (the overview of our work paradigm is in Fig.), we can successfully locate the LIP subnetworks at the sparsity range of 20%-86.58% in setting i; and those at the sparsity range of 5%-36% in setting ii. Those LIP subnetworks also possess high transferability. For example, the LIP ticket found in the setting i transfer well across not only different images, but also different tasks such as denoising, inpainting and super-resolution. Our contributions are summarized below:\n• The first comprehensive study on LTH in DNN-based image priors and inverse problems, establishing the \"lottery image prior\" (LIP) and demonstrating the prevailing relevance of LTH more broadly than previously typical settings. The last column (in blue) intends to display the results with the most extremely sparse subnetwork.\n• The investigation of both untrained and pre-trained DNNs as image priors, verifying that LIP subnetworks can be found in both settings, by overcoming several impediments such as severely limited training data and task objective mismatch. • High transferability of LIP subnetworks across data/datasets, and various inverse problem tasks. Our finding reflects the underlying common image prior that is agnostic to specific data or task, through the lens of the CNN architecture together with sparsity.\nIn this section, we will investigate the lottery image prior (LIP) property under setting i, for deep image prior (DIP) models. Model performance is measured by PSNR (Peak Signal to Noise Ratio) between the restored images and the clean ground truths (SSIM (Structural Similarity) results are in supplementary materials). We run all experiments with three different random seeds. All images used for plotting results are summarized in Fig..\nIn DIP, for each degraded image to be restored, an untrained DNN will be over-fitted over that single image (with proper early stopping). This casts a crucial difference from typical LTH settings where winning tickets are identified using IMP over a distribution of data and are verified to be effective when trained on data from that specific distribution. Therefore, besides the usual properties in winning tickets such as the existence, the superiority over other pruning methods, and the effect of rewinding, we will strive to answer two more questions about LIP in DIP. The first question is: can we extend the IMP algorithm for single-image DIP to multi-image and thus improve the performance of winning tickets hopefully? The second question is to what extend the LIP found in DIP setting can be transferred? Answering these two questions not only provides a clearer picture of LIP, but also hints a new perspective for a deeper understanding of LTH.\nIn DIP setting, we first find the winning tickets with LIP property by implementing the single-image IMP on the hourglass model (i.e., the DIP model used in. We adopt the modified objectives using clean images as labels as we discussed in Sec. 3.2. The algorithm is described in detail in Algorithm 1. We apply the implemented algorithm on Set5  ( and Set14 datasets to obtain the sparse subnetworks 1 and evaluate these subnetworks on the denoising task.\nResults of single-image IMP in Fig. (curves in red colors) verify that the LIP exists in the DIP setting. To be specific, during the IMP finding process when we use clean images in DIP objectives, we are able to find the winning tickets with LIP on untrained DNN at sparsity as high as 86.58%. While at the evaluation stage, when we only have access to the degraded images, we find that the winning tickets found with the modified objectives are still applicable, matching the dense performance at sparsity as high as 83.23%.\nBesides the dense model baselines, we also compare the single-image IMP with Random Pruning, and a pruning-at-initialization method SNIP, whose results are also presented in Fig. in other colors. Specifically, we clearly observe from the first row in Fig. that the singleimage IMP for DIP outperforms random pruning and SNIP at a wide sparsity range [20%, 96%]. Interestingly, we find random prune is a good competitor to SNIP sometimes, but both of them suffer significant performance decrease at extreme sparsities (over 80%), where IMP still persists.\nThe Effect of Weight Rewinding In this part, we study the effect of weight rewinding Is Multi-image IMP A Good Extension in DIP? DIP over-fits an untrained DNN on a single image. A reasonable conjecture is that the DNN will be dedicated to the features in that specific image and so should the resulting winning ticket be if we apply single-image IMP to the DIP model. We then ask that whether we can co-consider multiple images during IMP for DIP models to find winning tickets that are suitable for more general features and thus yield better image restoration performance? To verify our idea, we propose a new multi-image IMP for DIP where we replace the single-image DIP objective with the average of multiple images during the IMP process. Note that all images will share the same fixed random code during IMP. Otherwise, different random codes will intervene with one another because they lead to different winning tickets, resulting in a share subnetwork with inferior performance. The algorithm is formally described in Algorithm 2.\nWe evaluate the multi-image IMP in two different settings: (i) cross-domain setting where we apply the multi-image IMP to the five images from Set5; (2) single-domain setting where we apply the multi-image IMP to five images of human faces with glasses. We think images from Set 5 are from more diversified domains because they include bird, butterfly and human face contents. We compare single-image IMP winning tickets found on the Baby and the Woman images from Set5 with the cross-domain ticket, and the single-image IMP winning tickets found on Face-1 and Face-2 with the single-domain ticket. Results presented in Fig. show that multi-image IMP significantly improves the quality of the winning tickets in the cross-domain setting, which is aligned with our previous hypothesis.\nTo what extent can LIP tickets be transferred? Transferability is an important metric to measure the usefulness of LIP in the DIP setting. It would significantly undermine the practical application of LIP if the winning tickets can only be dedicatedly found for each image. In this part, we evaluate the transferability of LIP for DIP models from three perspectives, i.e., the transferability between images, between image restoration tasks and between high-level tasks.\nObservation 1: LIP can transfer across images. We identify the single-image LIPs for all image from Set5 and the multi-image LIP on Set5 using the new multi-image IMP proposed in the last part. Then we evaluate all the above LIPs on the Baby image, results being presented in Fig.. We can see that the LIPs found on other images, even those from the Bird and the Butterfly images, can perform comparably well with LIP dedicatedly found on the Baby image. This shows that LIP has reasonable transferability across images, even for those coming from slightly different domains (for example, the Baby and the Butterfly). We can also observe the fact that the multi-image LIP outperforms all single-image LIPs, as side support for the superiority of multi-image LIP in the cross-domain settings.\nObservation 2: LIP can transfer across image restoration tasks but not to other high-level tasks.  We test the denoising LIP on MNIST and CIFAR10 datasets (left 2 figures). Note that we replace the last convolutional layer of DIP models with the linear layer and load the same initial weights. We evaluate the CIFAR LIP on the denoising task.\ninterests? Furthermore, if the above question has an affirmative answer, is such transferability sustainable when transferring to or from some high-level tasks such as classification?\nTo evaluate the transferability of LIP between image restoration tasks, we first find three LIPs for the denoising, inpainting and super-resolution tasks respectively and then transfer between them, as shown in Fig.. We observe that a LIP winning ticket transferred from another image restoration task always yields restoration performance comparable with the single-image LIP found on the original task, sometimes even better, for examples in Fig.(a) and 7(g).\nWe then evaluate the transferability of LIP between the denoising task and image classification task on CIFAR-10. We apply the standard IMP on the DIP model, i.e., the hourglass architecture in, to obtain winning tickets on MNIST and CIFAR-10 datasets. We show the results of transferring the denoising LIP to MNIST in Fig.(a) and CIFAR-10 in 8(b) and the CIFAR-10 winning tickets to denoising task in Fig.). Although transferring denoising LIP to MNIST seems to yield winning tickets due to MNIST's low complexity, its transfer to CIFAR-10 is unsuccessful. Interestingly, the multi-image LIP becomes a worse ticket on CIFAR-10 than the single-image LIP. Moreover, transferring winning tickets on CIFAR-10 back to the denoising DIP task also fails to generate winning tickets that are comparable with denoising LIPs.\nBased on those observations, we conjecture that the architecture priors needed to \"win the lottery ticket\" may substantially differ between low-level (reconstruction, restoration,...) and high-level (classification, recognition,...) vision tasks, but seems to be quite overlapped/shareable among different tasks that are all low-level (or high-level). The high-level task transferability of winning tickets has been found in prior works. We believe this interesting \"incompatibility\" between low-level and high-level tasks is an unstudied new direction, and leave this for our future work.\nFor example, the LIP ticket found in the setting i transfer well across not only different images, but also different tasks such as denoising, inpainting and super-resolution.****Figure 5: We evaluate different single-image LIPs and the multi-image LIP on Baby image to measure LIP’s transferability (cross images).****For example, the LIP ticket found in the setting i transfer well across not only different images, but also different tasks such as denoising, inpainting and super-resolution.****Figure 7: Transferability (cross tasks) experimental results. We study the transferability of denoising LIP on the restoration tasks such as inpainting and super-resolution (SR); we also study the inpainting and SR LIP on the denoising task.

There are several ways in which such a dataset may be compiled. We present below the choices that we made.\nWe decided to use sentences involving at least one race- or gender-associated word. The sentences were intended to be short and grammatically simple. We also wanted some sentences to include expressions of sentiment and emotion, since the goal is to test sentiment and emotion systems. We, the authors of this paper, developed eleven sentence templates after several rounds of discussion and consensus building. They are shown in Table TABREF3 . The templates are divided into two groups. The first type (templates 1–7) includes emotion words. The purpose of this set is to have sentences expressing emotions. The second type (templates 8–11) does not include any emotion words. The purpose of this set is to have non-emotional (neutral) sentences.\nThe templates include two variables: INLINEFORM0 person INLINEFORM1 and INLINEFORM2 emotion word INLINEFORM3 . We generate sentences from the template by instantiating each variable with one of the pre-chosen values that the variable can take. Each of the eleven templates includes the variable INLINEFORM4 person INLINEFORM5 . INLINEFORM6 person INLINEFORM7 can be instantiated by any of the following noun phrases:\n\nFor our study, we chose ten names of each kind from the study by Caliskan:2017 (see Table TABREF7 ). The full lists of noun phrases representing females and males, used in our study, are shown in Table TABREF8 .\nThe second variable, INLINEFORM0 emotion word INLINEFORM1 , has two variants. Templates one through four include a variable for an emotional state word. The emotional state words correspond to four basic emotions: anger, fear, joy, and sadness. Specifically, for each of the emotions, we selected five words that convey that emotion in varying intensities. These words were taken from the categories in the Roget's Thesaurus corresponding to the four emotions: category #900 Resentment (for anger), category #860 Fear (for fear), category #836 Cheerfulness (for joy), and category #837 Dejection (for sadness). Templates five through seven include emotion words describing a situation or event. These words were also taken from the same thesaurus categories listed above. The full lists of emotion words (emotional state words and emotional situation/event words) are shown in Table TABREF10 .\nWe generated sentences from the templates by replacing INLINEFORM0 person INLINEFORM1 and INLINEFORM2 emotion word INLINEFORM3 variables with the values they can take. In total, 8,640 sentences were generated with the various combinations of INLINEFORM4 person INLINEFORM5 and INLINEFORM6 emotion word INLINEFORM7 values across the eleven templates. We manually examined the sentences to make sure they were grammatically well-formed. Notably, one can derive pairs of sentences from the EEC such that they differ only in one word corresponding to gender or race (e.g., `My daughter feels devastated' and `My son feels devastated').

        "question": "Please give me a summary of the text on the origins of skateboarding.",
        "evidence": "The first skateboards started with wooden boxes, or boards, with roller skate wheels attached to the bottom. Crate scooters preceded skateboards, having a wooden crate attached to the nose (front of the board), which formed rudimentary handlebars. The boxes turned into planks, similar to the skateboard decks of today.\n\nSkateboarding, as it exists today, was probably born sometime in the late 1940s, or early 1950s, when surfers in California wanted something to do when the waves were flat. This was called \"sidewalk surfing\" – a new wave of surfing on the sidewalk as the sport of surfing became highly popular. No one knows who made the first board; it seems that several people came up with similar ideas at around the same time. The first manufactured skateboards were ordered by a Los Angeles, California surf shop, meant to be used by surfers in their downtime. The shop owner, Bill Richard, made a deal with the Chicago Roller Skate Company to produce sets of skate wheels, which they attached to square wooden boards. Accordingly, skateboarding was originally denoted \"sidewalk surfing\" and early skaters emulated surfing style and maneuvers, and performed barefoot.\n\nBy the 1960s a small number of surfing manufacturers in Southern California such as Jack's, Kips', Hobie, Bing's and Makaha started building skateboards that resembled small surfboards, and assembled teams to promote their products. One of the earliest Skateboard exhibitions was sponsored by Makaha's founder, Larry Stevenson, in 1963 and held at the Pier Avenue Junior High School in Hermosa Beach, California. Some of these same teams of skateboarders were also featured on a television show called Surf's Up in 1964, hosted by Stan Richards, that helped promote skateboarding as something new and fun to do.\n\nAs the popularity of skateboarding began expanding, the first skateboarding magazine, The Quarterly Skateboarder was published in 1964. John Severson, who published the magazine, wrote in his first editorial:\n\nToday's skateboarders are founders in this sport—they're pioneers—they are the first. There is no history in Skateboarding—its being made now—by you. The sport is being molded and we believe that doing the right thing now will lead to a bright future for the sport. Already, there are storm clouds on the horizon with opponents of the sport talking about ban and restriction.\n\nThe magazine only lasted four issues, but resumed publication as Skateboarder in 1975. The first broadcast of an actual skateboarding competition was the 1965 National Skateboarding Championships, which were held in Anaheim, California and aired on ABC's Wide World of Sports. Because skateboarding was a new sport during this time, there were only two original disciplines during competitions: flatland freestyle and slalom downhill racing.\n\nAnimated cartoons of the time occasionally featured skateboard gags. Two Road Runner cartoons made in 1965, Shot and Bothered and Out and Out Rout, feature Wile E. Coyote riding a skateboard.\n\nOne of the earliest sponsored skateboarders, Patti McGee, was paid by Hobie and Vita Pak to travel around the country to do skateboarding exhibitions and to demonstrate skateboarding safety tips. McGee made the cover of Life magazine in 1965 and was featured on several popular television programs—The Mike Douglas Show, What's My Line? and The Tonight Show Starring Johnny Carson—which helped make skateboarding even more popular at the time. Some other well known surfer-style skateboarders of the time were Danny Bearer, Torger Johnson, Bruce Logan, Bill and Mark Richards, Woody Woodward, and Jim Fitzpatrick.\n\nThe growth of the sport during this period can also be seen in sales figures for Makaha, which quoted $4 million worth of board sales between 1963 and 1965. By 1966 a variety of sources began to claim that skateboarding was dangerous, resulting in shops being reluctant to sell them, and parents being reluctant to buy them. In 1966 sales had dropped significantly and Skateboarder Magazine had stopped publication. The popularity of skateboarding dropped and remained low until the early 1970s.",
        "answer": "Sidewalk surfing, known today as skateboarding, originated in the late 1940s out of the desire of California surfers hoping to still ride when waves were flat. By the 1960s, a small number of surfing manufacturers began selling skateboards hoping to bring more attention to the sport. Skateboarding began to rapidly increase in popularity in the 1970s due to improvements to the design elements and materials used on the boards.",

        "question": "What are the quantitative methods suitable to do?",
        "answer": "Quantitative methods are suitable to study observable behaviour.",
        "evidence": "As explained in the introduction, the overarching aim of this project is to investigate in how far information conveyed in social media posts can complement more traditional research methods in clinical psychology to get insights into the recovery experience of individuals with a BD diagnosis. Therefore, we will first conduct a systematic literature review of qualitative evidence to establish a solid base of what is already known about personal recovery experiences in BD for the subsequent social media studies.\nOur research questions, which regard the experiences of different populations, lend themselves to several subprojects. First, we will collect and analyse English-language data from westerners. Then, we will address ethnically diverse English-speaking populations and finally multilingual accounts. This has the advantage that we can build data processing and methodological workflows along an increase in complexity of the data collection and analysis throughout the project.\nIn each project phase, we will employ a mixed-methods approach to combine the advantages of quantitative and qualitative methods BIBREF52 , BIBREF53 , which is established in mental health research BIBREF54 , BIBREF55 , BIBREF56 , BIBREF57 and specifically recommended to investigate personal recovery BIBREF58 . Quantitative methods are suitable to study observable behaviour such as language and yield more generalisable results by taking into account large samples. However, they fall short of capturing the subjective, idiosyncratic meaning of socially constructed reality, which is important when studying individuals' recovery experience BIBREF59 , BIBREF22 , BIBREF23 , BIBREF60 . Therefore, we will apply an explanatory sequential research design BIBREF53 , starting with statistical analysis of the full dataset followed by a manual investigation of fewer examples, similar to `distant reading' BIBREF61 in digital humanities.\nSince previous research mainly employed (semi-)structured interviews and we do not expect to necessarily find the same aspects emphasised in unstructured settings, even less so when looking at a more diverse and non-English speaking population, we will not derive hypotheses from existing recovery models for testing on the online data. Instead, we will start off with exploratory quantitative research using comparative analysis tools such as Wmatrix BIBREF62 to uncover important linguistic features, e.g., on keywords and key concepts that occur with unexpected frequency in our collected datasets relative to reference corpora. The underlying assumption is that keywords and key concepts are indicative of certain aspects of personal recovery, such as those specified in the CHIME model BIBREF24 , other previous research BIBREF22 , BIBREF23 , BIBREF60 , or novel ones. Comparing online sources with transcripts of structured interviews or subcorpora originating from different cultural backgrounds might uncover aspects that were not prominently represented in the accounts studied in prior research.\nA specific challenge will be to narrow down the data to parts relevant for personal recovery, since there is no control over the discussed topics compared to structured interviews. To investigate how individuals discuss personal recovery online and what (potentially unrecorded) aspects they associate with it, without a priori narrowing down the search-space to specific known keywords seems like a chicken-and-egg problem. We propose to address this challenge by an iterative approach similar to the one taken in a corpus linguistic study of cancer metaphors BIBREF63 . Drawing on results from previous qualitative research BIBREF24 , BIBREF23 , we will compile an initial dictionary of recovery-related terms. Next, we will examine a small portion of the dataset manually, which will be partly randomly sampled and partly selected to contain recovery-related terms. Based on this, we will be able to expand the dictionary and additionally automatically annotate semantic concepts of the identified relevant text passages using a semantic tagging approach such as the UCREL Semantic Analysis System (USAS) BIBREF64 . Crucially for the multilingual aspect of the project, USAS can tag semantic categories in eight languages BIBREF8 . Then, semantic tagging will be applied to the full corpus to retrieve all text passages mentioning relevant concepts. Furthermore, distributional semantics methods BIBREF65 , BIBREF66 can be used to find terms that frequently co-occur with words from our keyword dictionary. Occurrences of the identified keywords or concepts can be quantified in the full corpus to identify the importance of the related personal recovery aspects.\nLinguistic Inquiry and Word Count (LIWC) BIBREF67 is a frequently used tool in social-science text analysis to analyse emotional and cognitive components of texts and derive features for classification models BIBREF47 , BIBREF46 , BIBREF68 , BIBREF69 . LIWC counts target words organised in a manually constructed hierarchical dictionary without contextual disambiguation in the texts under analysis and has been psychometrically validated and developed for English exclusively. While translations for several languages exist, e.g., Dutch BIBREF9 , and it is questionable to what extent LIWC concepts can be transferred to other languages and cultures by mere translation. We therefore aim to apply and develop methods that require less manual labour and are applicable to many languages and cultures. One option constitute unsupervised methods, such as topic modelling, which has been applied to explore cultural differences in mental-health related online data already BIBREF37 , BIBREF36 . The Differential Language Analysis ToolKit (DLATK) BIBREF70 facilitates social-scientific language analyses, including tools for preprocessing, such as emoticon-aware tokenisers, filtering according to meta data, and analysis, e.g. via robust topic modelling methods.\nFurthermore, emotion and sentiment analysis constitute useful tools to investigate the emotions involved in talking about recovery and identify factors that facilitate or hinder it. There are many annotated datasets to train supervised classifiers BIBREF71 , BIBREF3 for these actively researched NLP tasks. Machine learning methods were found to usually outperform rule-based approaches based on look-ups in dictionaries such as LIWC. Again, most annotated resources are English, but state of the art approaches based on multilingual embeddings allow transferring models between languages BIBREF4 .\nQuantitative methods are suitable to study observable behaviour such as language and yield more generalisable results by taking into account large samples.",

        "question": "What kind of algorithm can be used to identify stance towards rumors based on sequential annotations in supervised models?",
        "answer": "An algorithm for learning from sequential or time series data could be used.",
        "evidence": "Supervised learning is frequently used to scale up analyses. For example, BIBREF42 wanted to analyze the motivations of Movember campaign participants. By developing a classifier based on a small set of annotations, they were able to expand the analysis to over 90k participants.\nThe choice of supervised learning model is often guided by the task definition and the label types. For example, to identify stance towards rumors based on sequential annotations, an algorithm for learning from sequential BIBREF43 or time series data BIBREF44 could be used. The features (sometimes called variables or predictors) are used by the model to make the predictions. They may vary from content-based features such as single words, sequences of words, or information about their syntactic structure, to meta-information such as user or network information. Deciding on the features requires experimentation and expert insight and is often called feature engineering. For insight-driven analysis, we are often interested in why a prediction has been made and features that can be interpreted by humans may be preferred. Recent neural network approaches often use simple features as input (such as word embeddings or character sequences), which requires less feature engineering but make interpretation more difficult.\nSupervised models are powerful, but they can latch on to spurious features of the dataset. This is particularly true for datasets that are not well-balanced, and for annotations that are noisy. In our introductory example on hate speech in Reddit BIBREF0 , the annotations are automatically derived from the forum in which each post appears, and indeed, many of the posts in the forums (subreddits) that were banned by Reddit would be perceived by many as hate speech. But even in banned subreddits, not all of the content is hate speech (e.g., some of the top features were self-referential like the name of the subreddit) but a classifier would learn a high weight for these features.\nEven when expert annotations are available on the level of individual posts, spurious features may remain. BIBREF45 produced expert annotations of hate speech on Twitter. They found that one of the strongest features for sexism is the name of an Australian TV show, because people like to post sexist comments about the contestants. If we are trying to make claims about what inhibits or encourages hate speech, we would not want those claims to be tied to the TV show's popularity. Such problems are inevitable when datasets are not well-balanced over time, across genres, topics, etc. Especially with social media data, we lack a clear and objective definition of `balance' at this time.\nThe risk of supervised models latching on to spurious features reinforces the need for interpretability. Although the development of supervised models is usually performance driven, placing more emphasis on interpretability could increase the adoption of these models in insight-driven analyses. One way would be to only use models that are already somewhat interpretable, for example models that use a small number of human-interpretable features. Rather than imposing such restrictions, there is also work on generating post-hoc explanations for individual predictions (e.g., BIBREF46 ), even when the underlying model itself is very complex.\nFor example, to identify stance towards rumors based on sequential annotations, an algorithm for learning from sequential [Zubiaga et al., 2016a] or time series data [Lukasik et al., 2016] could be used.",

        "question": "How does Dolores work?",
        "answer": "Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model.",
        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nDolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model.",

The complexity of the affine transformation method (section 4.1) can be expressed as O(k2m2d3) and that of the MAP SE method is O(km2d3). Here m is the number of symbols, k is the number of components, and d is the dimension. The reviewer is correct in observing that when m and/or k is large, the complexity of adaptation would be high.

The affine transformation method of § 4.1 computes the posterior distribution Pθbc (x, i| y) over the set of symbols and components (of size m k). Computation of each exponent factor in the posterior distribution requires O(d 3 ) operations for the full-covariance case, and O(d) operations for the diagonal covariance case.

        "evidence": "The use of categorical attributes (e.g., user, topic, aspects) in the sentiment analysis community BIBREF0, BIBREF1, BIBREF2 is widespread. Prior to the deep learning era, these information were used as effective categorical features BIBREF3, BIBREF4, BIBREF5, BIBREF6 for the machine learning model. Recent work has used them to improve the overall performance BIBREF7, BIBREF8, interpretability BIBREF9, BIBREF10, and personalization BIBREF11 of neural network models in different tasks such as sentiment classification BIBREF12, review summarization BIBREF13, and text generation BIBREF8.\nIn particular, user and product information have been widely incorporated in sentiment classification models, especially since they are important metadata attributes found in review websites. BIBREF12 first showed significant accuracy increase of neural models when these information are used. Currently, the accepted standard method is to use them as additional biases when computing the weights $a$ in the attention mechanism, as introduced by BIBREF7 as:\nwhere $u$ and $p$ are the user and product embeddings, and $h$ is a word encoding from BiLSTM. Since then, most of the subsequent work attempted to improve the model by extending the model architecture to be able to utilize external features BIBREF14, handle cold-start entities BIBREF9, and represent user and product separately BIBREF15.\nIntuitively, however, this method is not the ideal method to represent and inject attributes because of two reasons. First, representing attributes as additional biases cannot model the relationship between the text and attributes. Rather, it only adds a user- and product-specific biases that are independent from the text when calculating the attention weights. Second, injecting the attributes in the attention mechanism means that user and product information are only used to customize how the model choose which words to focus on, as also shown empirically in previous work BIBREF7, BIBREF15. However, we argue that there are more intuitive locations to inject the attributes such as when contextualizing words to modify their sentiment intensity.\nWe propose to represent user and product information as weight matrices (i.e., $W$ in the equation above). Directly incorporating these attributes into $W$ leads to large increase in parameters and subsequently makes the model difficult to optimize. To mitigate these problems, we introduce chunk-wise importance weight matrices, which (1) uses a weight matrix smaller than $W$ by a chunk size factor, and (2) transforms these matrix into gates such that it corresponds to the relative importance of each neuron in $W$. We investigate the use of this method when injected to several locations in the base model: word embeddings, BiLSTM encoder, attention mechanism, and logistic classifier.\nThe results of our experiments can be summarized in three statements. First, our preliminary experiments show that doing bias-based attribute representation and attention-based injection is not an effective method to incorporate user and product information in sentiment classification models. Second, despite using only a simple BiLSTM with attention classifier, we significantly outperform previous state-of-the-art models that use more complicated architectures (e.g., models that use hierarchical models, external memory networks, etc.). Finally, we show that these attribute representations transfer well to other tasks such as product category classification and review headline generation.\nSecond, despite using only a simple BiLSTM with attention classifier, we significantly outperform previous state-of-the-art models that use more complicated architectures (e.g., models that use hierarchical models, external memory networks, etc.).",

        "evidence": "In our experimental setup, an ideal context encoder should capture the generalizable information for task inference, namely the difference between reward/dynamics functions across a distribution of tasks. However, as discussed in Section 1, there are two major challenges that impede conventional COMRL algorithms from learning robust representations:  MDP ambiguity arises due to COMRL algorithms' sensitivity to fixed dataset distributions. Take Sparse-Point-Robot for example, as in Figure, for tasks with a goal on the semicircle, the state-action distribution exhibits specific pattern which may reflect task identity. Given D = {(s, a, s , r)} as input, the context encoder may learn a spurious correlation between state-action distributions and task identity, which causes performance degradation under distribution shifts (Table).\nSparse reward in meta-environments could exacerbate MDP ambiguity by making a considerable portion of transitions uninformative for task inference, such as the samples outside any goals in Figure. Attention mechanism, especially the batch-wise channel attention, helps the context encoder attend to the informative portion of the input transitions, and therefore significantly improve the robustness of the learned policies.\nTo demonstrate the robustness of FOCAL++ in presence of the two challenges above, we tested it against distribution shift by using datasets of various qualities: expert, medium, random and mixed which combines all three. Shown in Table, we observe that overall the performance drop due to distribution shift is significantly lower when attention and contrastive learning are applied.\nMoreover, we are aware that even mixing of datasets generated by different behavior policies cannot fully eliminate the risk of MDP ambiguity since the state-action distributions for each task still do not completely overlap. To show that the attention modules introduced by FOCAL++ indeed works as intended by capturing the reward-task dependency, we create a new dataset on Sparse-Point-Robot by merging the state-action support across all tasks and relabelling the sparse reward according to the task-specific reward functions. In principle, this fully prevents information leakage from the state-action distributions, forcing the context encoder to learn to distinguish the reward functions between tasks while minimizing the contrastive loss. Shown in Figure, we experimented with 3 attention variants of FOCAL++ on the relabeled dataset, and found that batch-wise attention significantly improves the performance as intended. Additionally, we visualize the density distribution of batch-wise attention weights assigned to samples in Figure. We see a clear tendency for the batch-attention module to assign zero weight to samples with zero rewards (the absolutely sparse data points which lie outside all goal circles in Figure) and maximum weights to the non-zero-reward transitions, with binary classification AUC = 0.969, which is clear evidence of FOCAL++ learning the correct correlation for task inference by attending to the informative context.\nWe evaluate FOCAL++ on 6 continuous control meta-environments of robotic locomotion (Todorov et al., 2012) adopted from FOCAL. 4 (Sparse-Point-Robot, Sparse-Cheetah-Vel, Sparse-Cheetah-FwdBack, Sparse-Ant-Fwd-Back) and 2 (Point-Robot-Wind, Walker-2D-Params) environments require adaptation by reward and transition functions respectively. For inference, FOCAL++ aggregates context from a fixed test set to infer task embedding, and is subsequently evaluated online. Besides FOCAL, three other baselines are compared: an offline variant of the PEARL algorithm (Rakelly et al., 2019) (Batch PEARL), a context-based offline BCQ algorithm (Fujimoto et al., 2019) (Contextual BCQ) and a two-stage COMRL algorithm with reward/dynamics relabelling (Li et al., 2019) (MBML).****Figure 5: Result on the relabeled Sparse-Point-Robot dataset. (a) State distributions of the expert datasets for 20 distinct tasks, with goals uniformly distributed on a semicircle. (b) On mixed dataset, FOCAL completely fails in this scenario whereas FOCAL++ variants with batch-wise attention are able to learn.

        "question": "Does the authors' system outperform a strong rivaling system by a margin?",
        "answer": "Yes, it does.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.",

        "evidence": "Language modeling is a probabilistic description of language phenomenon. It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nRecurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks [1] have been the typical solution to language modeling which do achieve strong results.

Top 3 performances in each data category are shown in bold. The average is calculated as the average of accuracy for each category (For MSRP, we take the accuracy). )\nWe use a standard set of supervised as well as unsupervised benchmark tasks from the literature to evaluate our trained models, following BIBREF16 . The breadth of tasks allows to fairly measure generalization to a wide area of different domains, testing the general-purpose quality (universality) of all competing sentence embeddings. For downstream supervised evaluations, sentence embeddings are combined with logistic regression to predict target labels. In the unsupervised evaluation for sentence similarity, correlation of the cosine similarity between two embeddings is compared to human annotators.\nDownstream Supervised Evaluation. Sentence embeddings are evaluated for various supervised classification tasks as follows. We evaluate paraphrase identification (MSRP) BIBREF25 , classification of movie review sentiment (MR) BIBREF26 , product reviews (CR) BIBREF27 , subjectivity classification (SUBJ) BIBREF28 , opinion polarity (MPQA) BIBREF29 and question type classification (TREC) BIBREF30 . To classify, we use the code provided by BIBREF22 in the same manner as in BIBREF16 . For the MSRP dataset, containing pairs of sentences INLINEFORM0 with associated paraphrase label, we generate feature vectors by concatenating their Sent2Vec representations INLINEFORM1 with the component-wise product INLINEFORM2 . The predefined training split is used to tune the L2 penalty parameter using cross-validation and the accuracy and F1 scores are computed on the test set. For the remaining 5 datasets, Sent2Vec embeddings are inferred from input sentences and directly fed to a logistic regression classifier. Accuracy scores are obtained using 10-fold cross-validation for the MR, CR, SUBJ and MPQA datasets. For those datasets nested cross-validation is used to tune the L2 penalty. For the TREC dataset, as for the MRSP dataset, the L2 penalty is tuned on the predefined train split using 10-fold cross-validation, and the accuracy is computed on the test set.\nWe propose a new unsupervised model, Sent2Vec, for learning universal sentence embeddings. Conceptually, the model can be interpreted as a natural extension of the word-contexts from C-BOW BIBREF0 , BIBREF1 to a larger sentence context, with the sentence words being specifically optimized towards additive combination over the sentence, by means of the unsupervised objective function.\nThe ParagraphVector DBOW model BIBREF14 is a log-linear model which is trained to learn sentence as well as word embeddings and then use a softmax distribution to predict words contained in the sentence given the sentence vector representation. They also propose a different model ParagraphVector DM where they use n-grams of consecutive words along with the sentence vector representation to predict the next word.\nBIBREF16 propose a Sequential (Denoising) Autoencoder, S(D)AE. This model first introduces noise in the input data: Firstly each word is deleted with probability INLINEFORM0 , then for each non-overlapping bigram, words are swapped with probability INLINEFORM1 . The model then uses an LSTM-based architecture to retrieve the original sentence from the corrupted version. The model can then be used to encode new sentences into vector representations. In the case of INLINEFORM2 , the model simply becomes a Sequential Autoencoder. BIBREF16 also propose a variant (S(D)AE + embs.) in which the words are represented by fixed pre-trained word vector embeddings.\nThe SkipThought model BIBREF22 combines sentence level models with recurrent neural networks. Given a sentence INLINEFORM0 from an ordered corpus, the model is trained to predict INLINEFORM1 and INLINEFORM2 .\nFastSent BIBREF16 is a sentence-level log-linear bag-of-words model. Like SkipThought, it uses adjacent sentences as the prediction target and is trained in an unsupervised fashion. Using word sequences allows the model to improve over the earlier work of paragraph2vec BIBREF14 . BIBREF16 augment FastSent further by training it to predict the constituent words of the sentence as well. This model is named FastSent + AE in our comparisons.\nIn a very different line of work, C-PHRASE BIBREF20 relies on additional information from the syntactic parse tree of each sentence, which is incorporated into the C-BOW training objective.\nCompared to our approach, Siamese C-BOW BIBREF23 shares the idea of learning to average word embeddings over a sentence. However, it relies on a Siamese neural network architecture to predict surrounding sentences, contrasting our simpler unsupervised objective.\nFLOAT SELECTED: Table 2: Unsupervised Evaluation Tasks: Comparison of the performance of different models on Spearman/Pearson correlation measures. An underline indicates the best performance for the dataset. Top 3 performances in each data category are shown in bold. The average is calculated as the average of entries for each correlation measure.\nIn Tables TABREF18 and TABREF19 , we compare our results with those obtained by BIBREF16 on different models. Table TABREF21 in the last column shows the dramatic improvement in training time of our models (and other C-BOW-inspired models) in contrast to neural network based models. All our Sent2Vec models are trained on a machine with 2x Intel Xeon E5 INLINEFORM0 2680v3, 12 cores @2.5GHz.\nAlong with the models discussed in Section SECREF3 , this also includes the sentence embedding baselines obtained by simple averaging of word embeddings over the sentence, in both the C-BOW and skip-gram variants. TF-IDF BOW is a representation consisting of the counts of the 200,000 most common feature-words, weighed by their TF-IDF frequencies. To ensure coherence, we only include unsupervised models in the main paper.

        "question": "Who made the first individual effort in Yugoslavia?",
        "answer": "The first individual effort was made by Vladimir Matkovi´c from the Institute for Telecommunications in Zagreb in 1957 in his PhD thesis on entropy in the Croatian language.",
        "evidence": "In Yugoslavia, organized effort in machine translation started in 1959, but the first individual effort was made by Vladimir Matković from the Institute for Telecommunications in Zagreb in 1957 in his PhD thesis on entropy in the Croatian language BIBREF10. The main research group in machine translation was formed in 1958, at the Circle for Young Linguists in Zagreb, initiated by a young linguist Bulcsu Laszlo, who graduated in Russian language, Southern Slavic languages and English language and literature at the University of Zagreb in 1952. The majority of the group members came from different departments of the Faculty of Humanities and Social Sciences of the University of Zagreb, with several individuals from other institutions. The members from the Faculty of Humanities and Social Sciences were: Svetozar Petrović (Department of Comparative Literature), Stjepan Babić (Department of Serbo-Croatian Language and Literature), Krunoslav Pranjić (Department of Serbo-Croatian Language and Literature), Željko Bujas (Department of English Language and Literature), Malik Mulić (Department of Russian Language and Literature) and Bulcsu Laszlo (Department of Comparative Slavistics). The members of the research group from outside the Faculty of Humanities and Social Sciences were: Božidar Finka (Institute for Language of the Yugoslav Academy of Sciences and Arts), Vladimir Vranić (Center for Numerical Research of the Yugoslav Academy of Sciences and Arts), Vladimir Matković (Institute for Telecommunications), Vladimir Muljević (Institute for Regulatory and Signal Devices) BIBREF10.\nLaszlo and Petrović BIBREF11 also commented on the state of the art of the time, noting the USA prototype efforts from 1954 and the publication of a collection of research papers in 1955 as well as the USSR efforts starting from 1955 and the UK prototype from 1956. They do not detail or cite the articles they mention. However, the fact that they referred to them in a text published in 1959 (probably prepared for publishing in 1958, based on BIBREF11, where Laszlo and Petrović described that the group had started its work in 1958) leads us to the conclusion that the poorly funded Croatian research was lagging only a couple of years behind the research of the superpowers (which invested heavily in this effort). Another interesting moment, which they delineated in BIBREF11, is that the group soon discovered that some experimental work had already been done in 1957 at the Institute of Telecommunications (today a part of the Faculty of Electrical Engineering and Computing at the University of Zagreb) by Vladimir Matković. Because of this, they decided to include him in the research group of the Faculty of Humanities and Social Sciences at the University of Zagreb. The work done by Matković was documented in his doctoral dissertation but remained unpublished until 1959.\nThe Russian machine translation pioneer Andreev expressed hope that the Yugoslav (Croatian) research group could create a prototype, but sadly, due to the lack of federal funding, this never happened BIBREF10. Unlike their colleagues in the USA and the USSR, Laszlo’s group had to manage without an actual computer (which is painfully obvious in BIBREF12), and the results remained mainly theoretical. Appealing probably to the political circles of the time, Laszlo and Petrović note that, although it sounds strange, research in computational linguistics is mainly a top-priority military effort in other countries BIBREF11. There is a quote from BIBREF10 which perhaps best delineates the optimism and energy that the researchers in Zagreb had:\n\"[...] The process of translation has to mechanicalized as soon as possible, and this is only possible if a competent, fast and inexhaustible machine which could inherit the translation task is created, even if just schematic. The machine needs to think for us. If machines help humans in physical tasks, why would they not help them in mental tasks with their mechanical memory and automated logic\" (p. 118).\nIn Yugoslavia, organized effort in machine translation started in 1959, but the first individual effort was made by Vladimir Matkovi´c from the Institute for Telecommunications in Zagreb in 1957 in his PhD thesis on entropy in the Croatian language [7].",

LexVec adjusts the PPMI matrix using context distribution smoothing BIBREF3 .\nWith the PPMI matrix calculated, the sliding window process is repeated and the following loss functions are minimized for every observed $(w,c)$ pair and target word $w$ : \n$$L_{wc} &= \\frac{1}{2} (u_w^\\top v_c - PPMI_{wc})^2 \\\\\n\nL_{w} &= \\frac{1}{2} \\sum \\limits _{i=1}^k{\\mathbf {E}_{c_i \\sim P_n(c)} (u_w^\\top v_{c_i} - PPMI_{wc_i})^2 }$$   (Eq. 4) \n where $u_w$ and $v_c$ are $d$ -dimensional word and context vectors. The second loss function describes how, for each target word, $k$ negative samples BIBREF2 are drawn from the smoothed context unigram distribution.\nGiven a set of subwords $S_w$ for a word $w$ , we follow fastText and replace $u_w$ in eq:lexvec2,eq:lexvec3 by $u^{\\prime }_w$ such that: \n$$u^{\\prime }_w = \\frac{1}{|S_w| + 1} (u_w + \\sum _{s \\in S_w} q_{hash(s)})$$   (Eq. 5) \n such that a word is the sum of its word vector and its $d$ -dimensional subword vectors $q_x$ .

        "evidence": "Our first dataset contains articles from celebrity magazines People, UsWeekly, and E!News. We labeled each article for whether it was reporting on men, women, or neither/unknown. To do this, we first extracted the article's topic tags. Some of these tags referred to people, but others to non-people entities, such as “Gift Ideas” or “Health.” To distinguish between these types of tags, we queried each tag on Wikipedia and checked whether the top page result contained a “Born” entry in its infobox – if so, we concluded that the tag referred to a person.\nThen, from the person's Wikipedia page, we determined their gender by checking whether the introductory paragraphs of the page contained more male or female pronouns. This method was simple but effective, since pronouns in the introduction almost always resolve to the subject of that page. In fact, on a sample of 80 tags that we manually annotated, we found that comparing pronoun counts predicted gender with perfect accuracy. Finally, if an article tagged at least one woman and did not tag any men, we labeled the article as Female; in the opposite case, we labeled it as Male.\nOur second dataset contains reviews from RateMyProfessors (RMP), an online platform where students can review their professors. We included all 5,604 U.S. schools on RMP, and collected all reviews for CS professors at those schools. We labeled each review with the gender of the professor whom it was about, which we determined by comparing the count of male versus female pronouns over all reviews for that professor. This method was again effective, because the reviews are expressly written about a certain professor, so the pronouns typically resolve to that professor.\nIn addition to extracting the text of the articles or reviews, for each dataset we also collected various useful metadata. For the celebrity dataset, we recorded each article's timestamp and the name of the author, if available. Storing author names creates the potential to examine the relationship between the gender of the author and the gender of the subject, such as asking if there are differences between how women write about men and how men write about men. In this work, we did not yet pursue this direction because we wanted to begin with a simpler question of how gender is discussed: regardless of the gender of the authors, what is the content being put forth and consumed? Furthermore, we were unable to extract author gender in the professor dataset since the RMP reviews are anonymous. However, in future work, we may explore the influence of author gender in the celebrity dataset.\nFor the professor dataset, we captured metadata such as each review's rating, which indicates how the student feels about the professor on a scale of AWFUL to AWESOME. This additional variable in our data creates the option in future work to factor in sentiment; for example, we could study whether there are differences in language used when criticizing a female versus a male professor.\nOur first dataset contains articles from celebrity magazines People, UsWeekly, and E!News.",

        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm.

The most basic linguistic unit in Vietnamese is morpheme, similar with syllable or token in English and “hình vị” (phoneme) or “tiếng” (syllable) in Vietnamese. According to the structured rule of its, Vietnamese can have about 20,000 different syllables (tokens). However, there are about 8,000 syllables used the Vietnamese dictionaries. There are three methods to identify morphemes in Vietnamese text BIBREF10 .\nMorpheme is the smallest meaningful unit of Vietnamese.\nMorpheme is the basic unit of Vietnamese.\nMorpheme is the smallest meaningful unit and is not used independently in the syntax factor.\nIn computational linguistics, morpheme is the basic unit of languages as Leonard Bloomfield mentioned for English BIBREF11 . In our research for Vietnamese, we consider the morpheme as syllable, called “tiếng” in Vietnamese (as Nguyen’s definition BIBREF12 ).\nThe next concept in linguistics is word which has fully grammar and meaning function in sentences. For Vietnamese, word is a single morpheme or a group of morphemes, which are fixed and have full meaning BIBREF12 . According to Nguyen, Vietnamese words are able classified into two types, (1) 1- syllable words with fully meaning and (2) n-syllables words whereas these group of tokens are fixed. Vietnamese syllable is not fully meaningful. However, it is also explained in the meaning and structure characteristics. For example, the token “kỳ” in “quốc kỳ” whereas “quốc” means national, “kỳ” means flag. Therefore, “quốc kỳ” means national flag.\nConsider dictionary used for evaluating the corpus, extracting features for models, and evaluating the systems, there are many Vietnamese dictionaries, however we recommend the Vietnamese dictionary of Hoang Phe, so called Hoang Phe Dictionary. This dictionary has been built by a group of linguistical scientists at the Linguistic Institute, Vietnam. It was firstly published in 1988, reprinted and extended in 2000, 2005 and 2010. The dictionary currently has 45,757 word items with 15,901 Sino-Vietnamese word items (accounting for 34.75%) BIBREF13 .\nVietnamese, like many languages in continental East Asia, is an isolating language and one branch of Mon-Khmer language group.",

        "answer": "The inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form.",
        "evidence": "Neural machine translation has recently achieved impressive results BIBREF0 , BIBREF1 , while learning from raw, sentence-aligned parallel text and using little in the way of external linguistic information. However, we hypothesize that various levels of linguistic annotation can be valuable for neural machine translation. Lemmatisation can reduce data sparseness, and allow inflectional variants of the same word to explicitly share a representation in the model. Other types of annotation, such as parts-of-speech (POS) or syntactic dependency labels, can help in disambiguation. In this paper we investigate whether linguistic information is beneficial to neural translation models, or whether their strong learning capability makes explicit linguistic features redundant.\nLet us motivate the use of linguistic features using examples of actual translation errors by neural MT systems. In translation out of English, one problem is that the same surface word form may be shared between several word types, due to homonymy or word formation processes such as conversion. For instance, close can be a verb, adjective, or noun, and these different meanings often have distinct translations into other languages. Consider the following English INLINEFORM0 German example:\nFor the English source sentence in Example SECREF4 (our translation in Example SECREF5 ), a neural MT system (our baseline system from Section SECREF4 ) mistranslates close as a verb, and produces the German verb schließen (Example SECREF6 ), even though close is an adjective in this sentence, which has the German translation nah. Intuitively, part-of-speech annotation of the English input could disambiguate between verb, noun, and adjective meanings of close.\nAs a second example, consider the following German INLINEFORM0 English example:\nGerman main clauses have a verb-second (V2) word order, whereas English word order is generally SVO. The German sentence (Example UID7 ; English reference in Example UID8 ) topicalizes the predicate gefährlich 'dangerous', putting the subject die Route 'the route' after the verb. Our baseline system (Example UID9 ) retains the original word order, which is highly unusual in English, especially for prose in the news domain. A syntactic annotation of the source sentence could support the attentional encoder-decoder in learning which words in the German source to attend (and translate) first.\nWe will investigate the usefulness of linguistic features for the language pair German INLINEFORM0 English, considering the following linguistic features:\nThe inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form. The other linguistic features are motivated by disambiguation, as discussed in our introductory examples.\nWe will investigate the usefulness of linguistic features for the language pair German↔English, considering the following linguistic features: The inclusion of lemmas is motivated by the hope for a better generalization over inflectional variants of the same word form.",

In September 2007, dehydrated tardigrades were taken into low Earth orbit on the FOTON-M3 mission carrying the BIOPAN astrobiology payload. For 10 days, groups of tardigrades, some of them previously dehydrated, some of them not, were exposed to the hard vacuum of outer space, or vacuum and solar UV radiation. Back on Earth, more than 68% of the subjects protected from solar UV radiation were reanimated within 30 minutes following rehydration, although subsequent mortality was high; many of these produced viable embryos. In contrast, hydrated samples exposed to the combined effect of vacuum and full solar UV radiation had significantly reduced survival, with only three subjects of Milnesium tardigradum surviving. Also, it was found that the space vacuum did not have a significant effect on egg-laying in either R. coronifer or M. tardigradum. However, M. tardigradum exposed to UV radiation had a lower egg laying rate. In May 2011, Italian scientists sent tardigrades on board the International Space Station along with extremophiles on STS-134, the final flight of Space Shuttle Endeavour. Their conclusion was that microgravity and cosmic radiation \"did not significantly affect survival of tardigrades in flight, and stated that tardigrades represent a useful animal for space research.\" In November 2011, they were among the organisms to be sent by the U.S.-based Planetary Society on the Russian Fobos-Grunt mission's Living Interplanetary Flight Experiment to Phobos; however, the launch failed.

        "evidence": "The task of speculation detection and scope resolution is critical in distinguishing factual information from speculative information. This has multiple use-cases, like systems that determine the veracity of information, and those that involve requirement analysis. This task is particularly important to the biomedical domain, where patient reports and medical articles often use this feature of natural language. This task is commonly broken down into two subtasks: the first subtask, speculation cue detection, is to identify the uncertainty cue in a sentence, while the second subtask: scope resolution, is to identify the scope of that cue. For instance, consider the example:\nIt might rain tomorrow.\nThe speculation cue in the sentence above is ‘might’ and the scope of the cue ‘might’ is ‘rain tomorrow’. Thus, the speculation cue is the word that expresses the speculation, while the words affected by the speculation are in the scope of that cue.\nThis task was the CoNLL-2010 Shared Task (BIBREF0), which had 3 different subtasks. Task 1B was speculation cue detection on the BioScope Corpus, Task 1W was weasel identification from Wikipedia articles, and Task 2 was speculation scope resolution from the BioScope Corpus. For each task, the participants were provided the train and test set, which is henceforth referred to as Task 1B CoNLL and Task 2 CoNLL throughout this paper.\nFor our experimentation, we use the sub corpora of the BioScope Corpus (BIBREF1), namely the BioScope Abstracts sub corpora, which is referred to as BA, and the BioScope Full Papers sub corpora, which is referred to as BF. We also use the SFU Review Corpus (BIBREF2), which is referred to as SFU.\nThis subtask of natural language processing, along with another similar subtask, negation detection and scope resolution, have been the subject of a body of work over the years. The approaches used to solve them have evolved from simple rule-based systems (BIBREF3) based on linguistic information extracted from the sentences, to modern deep-learning based methods. The Machine Learning techniques used varied from Maximum Entropy Classifiers (BIBREF4) to Support Vector Machines (BIBREF5,BIBREF6,BIBREF7,BIBREF8), while the deep learning approaches included Recursive Neural Networks (BIBREF9,BIBREF10), Convolutional Neural Networks (BIBREF11) and most recently transfer learning-based architectures like Bidirectional Encoder Representation from Transformers (BERT) (BIBREF12). Figures FIGREF1 and FIGREF1 contain a summary of the papers addressing speculation detection and scope resolution (BIBREF13, BIBREF5, BIBREF9, BIBREF3, BIBREF14, BIBREF15, BIBREF16, BIBREF17, BIBREF6, BIBREF11, BIBREF18, BIBREF10, BIBREF19, BIBREF7, BIBREF4, BIBREF8).\nInspired by the most recent approach of applying BERT to negation detection and scope resolution (BIBREF12), we take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT (BIBREF20), XLNet (BIBREF21) and RoBERTa (BIBREF22), applied to speculation detection and scope resolution. We evaluate the performance of each model across all datasets via the single dataset training approach, and report all scores including inter-dataset scores (i.e. train on one dataset, evaluate on another) to test the generalizability of the models. This approach outperforms all existing systems on the task of speculation detection and scope resolution. Further, we jointly train on multiple datasets and obtain improvements over the single dataset training approach on most datasets.\nContrary to results observed on benchmark GLUE tasks, we observe XLNet consistently outperforming RoBERTa. To confirm this observation, we apply these models to the negation detection and scope resolution task, and observe a continuity in this trend, reporting state-of-the-art results on three of four datasets on the negation scope resolution task.\nThe rest of the paper is organized as follows: In Section 2, we provide a detailed description of our methodology and elaborate on the experimentation details. In Section 3, we present our results and analysis on the speculation detection and scope resolution task, using the single dataset and the multiple dataset training approach. In Section 4, we show the results of applying XLNet and RoBERTa on negation detection and scope resolution and propose a few reasons to explain why XLNet performs better than RoBERTa. Finally, the future scope and conclusion is mentioned in Section 5.\nwe take this approach one step further by performing a comparative analysis of three popular transformer-based architectures: BERT, XLNet and RoBERTa, applied to speculation detection and scope resolution.",

Due to this reflex issue, as soon as we put him in the bed, he wakes up immediately and started to cry as the milk comes up from his stomach to his mouth. We are at-least a bit lucky here as he sleeps on our hands. Some babies may have colic and cries with no reason. That would have been much worse situation to be in.\n* You might be wondering how to hold the baby properly and how to change diapers and so on and forth.

Extractive summarization is a task to create summaries by pulling out snippets of text form the original text and combining them to form a summary. Abstractive summarization asks to generate summaries from scratch without the restriction to use the available words from the original text. Due to the limitations of extractive summarization on incoherent texts and unnatural methodology BIBREF0 , the research trend has shifted towards abstractive summarization.\nSequence-to-sequence models BIBREF1 with attention mechanism BIBREF2 have found great success in generating abstractive summaries, both from a single sentence BIBREF3 and from a long document with multiple sentences BIBREF4 . However, when generating summaries, it is necessary to determine the main topic and to sift out unnecessary information that can be omitted. Sequence-to-sequence models have the tendency to include all the information, relevant or not, that are found in the original text. This may result to unconcise summaries that concentrates wrongly on irrelevant topics. The problem is especially severe when summarizing longer texts.\nIn this paper, we propose to use entities found in the original text to infer the summary topic, mitigating the aforementioned problem. Specifically, we leverage on linked entities extracted by employing a readily available entity linking system. The importance of using linked entities in summarization is intuitive and can be explained by looking at Figure 1 as an example. First (O1 in the Figure), aside from auxiliary words to construct a sentence, a summary is mainly composed of linked entities extracted from the original text. Second (O2), we can depict the main topic of the summary as a probability distribution of relevant entities from the list of entities. Finally (O3), we can leverage on entity commonsense learned from a separate large knowledge base such as Wikipedia.\nTo this end, we present a method to effectively apply linked entities in sequence-to-sequence models, called Entity2Topic (E2T). E2T is a module that can be easily attached to any sequence-to-sequence based summarization model. The module encodes the entities extracted from the original text by an entity linking system (ELS), constructs a vector representing the topic of the summary to be generated, and informs the decoder about the constructed topic vector. Due to the imperfections of current ELS's, the extracted linked entities may be too ambiguous and coarse to be considered relevant to the summary. We solve this issue by using entity encoders with selective disambiguation and by constructing topic vectors using firm attention.\nWe experiment on two datasets, Gigaword and CNN, with varying lengths. We show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets. Moreover, when compared with the state-of-the-art models for each dataset, the model obtains a comparable performance on the Gigaword dataset where the texts are short, and outperforms all competing models on the CNN dataset where the texts are longer. Furthermore, we provide analysis on how our model effectively uses the extracted linked entities to produce concise and better summaries.\nWe show that applying our module to a sequence-to-sequence model with attention mechanism significantly increases its performance on both datasets.",

        "evidence": "Finally, we created a combined temporal-linguistic model. Since both the linguistic and the temporal models were built using the same framework, it was fairly simple to combine the two models. The combined model was created by merging the linguistic and temporal corpora and vocabularies. (Recall that we treated temporal features as words). We then experimented with the same four methods as in the last two sections to create our combined models.\nTable 4 shows the performance of each of these models. Across the board, the combined models outperformed their corresponding linguistic and temporal models, though the difference with the linguistic models were not as great. These results suggest that at some level the temporal and the linguistic \"styles\" of users provide non-overlapping cues about the identity of said users. Also, note that as with the linguistic and temporal models, our combined confusion model outperformed the other combined models.\nAnother way to evaluate the performance of the different combined models is through the rank-statistics plot. This is shown in Figure 2 . The figure shows the distribution of the ranks of the $5,612$ users for different combined models. The x-axis is the rank percentile (divided into bins of $5\\%$ ), the y-axis is the percentage of the users that fall in each bin. For example, for the confusion model, $69\\%$ (3880) of the $5,612$ users were correctly linked between Twitter and Facebook when looking at the top $5\\%$ (281) of the predictions by the model. From the figure, you can clearly see that the confusion model is superior to the other models, with TF-IDF a close second. You can also see from the figure that the rank plot for the random baseline is a horizontal line, with each rank percentile bin having $5\\%$ of the users ( $5\\%$ because the rank percentiles were divided into bins of $5\\%$ ).\nThe combined model was created by merging the linguistic and temporal corpora and vocabularies.",

        "evidence": "We aimed to mimic the presence of sparse/noisy content distribution, mandating the need to curate a novel dataset via specific lexicons. We scraped 500 random posts from recognized transport forum. A pool of 50 uni/bi-grams was created based on tf-idf representations, extracted from the posts, which was further pruned by annotators. Querying posts on Twitter with extracted lexicons led to a collection of $19,300$ tweets. In order to have lexical diversity, we added 2500 randomly sampled tweets to our dataset. In spite of the sparse nature of these posts, the lexical characteristics act as information cues.\nFigure FIGREF4 pictorially represents our methodology. Our approach required an initial set of informative tweets for which we employed two human annotators annotating a random sub-sample of the original dataset. From the 1500 samples, 326 were marked as informative and 1174 as non informative ($\\kappa =0.81$), discriminated on this criteria: Is the tweet addressing any complaint or raising grievances about modes of transport or services/ events associated with transportation such as traffic; public or private transport?. An example tweet marked as informative: No, metro fares will be reduced ???, but proper fare structure needs to presented right, it's bad !!!.\nWe utilized tf-idf for the identification of initial seed phrases from the curated set of informative tweets. 50 terms having the highest tf-idf scores were passed through the complete dataset and based on sub-string match, the transport relevant tweets were identified. The redundant tweets were filtered based on the cosine similarity score. Implicit information indicators were identified based on domain relevance score, a metric used to gauge the coverage of n-gram (1,2,3) when evaluated against a randomly created pool of posts.\nWe collected a pool of 5000 randomly sampled tweets different from the data collection period. The rationale behind having such a metric was to discard commonly occurring n-grams normalized by random noise and include ones which are of lexical importance. We used terms associated with high domain relevance score (threshold determined experimentally) as seed phrases for the next set of iterations. The growing dictionary augments the collection process. The process ran for 4 iterations providing us 7200 transport relevant tweets as no new lexicons were identified. In order to identify linguistic signals associated with the complaint posts, we randomly sampled a set of 2000 tweets which was used as training set, manually annotated into distinct labels: complaint relevant (702) and complaint non-relevant (1298) ($\\kappa =0.79$). We employed these features on our dataset.\nLinguistic markers. To capture linguistic aspects of complaints, we utilized Bag of Words, count of POS tags and Word2vec clusters.\nSentiment markers. We used quantified score based on the ratio of tokens mentioned in the following lexicons: MPQA, NRC, VADER and Stanford.\nInformation specific markers. These account for a set of handcrafted features associated with complaint, we used the stated markers (a) Text-Meta Data, this includes the count of URL's, hashtags, user mentions, special symbols and user mentions, used to enhance retweet impact; (b) Request Identification, we employed the model presented in BIBREF3 to identify if a specific tweet assertion is a request; (c) Intensifiers, we make use of feature set derived from the number of words starting with capital letters and the repetition of special symbols (exclamation, questions marks) within the same post; (d) Politeness Markers, we utilize the politeness score of the tweet extracted from the model presented in BIBREF3; (e) Pronoun Variation, these have the ability to reveal the personal involvement or intensify involvement. We utilize the frequency of pronoun types $\\lbrace \\textit {first, second, third, demonstrative and indefinite}$} using pre-defined dictionaries.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set. The results are reported in TableTABREF5 with 10 fold cross-validation. With increasing the number of iterations, the pool of seed phrases gets refined and augments the selection of transport relevant tweets. The proposed pipeline is tailored to identify complaint relevant tweets in a noisy scenario.\nFrom the pool of 7200 transport relevant tweets, we sampled 3500 tweets which were used as the testing set.",

The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are \"out\"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches. They communicate with two off-field scorers who record the match's statistical information.\n\nForms of cricket range from Twenty20, with each team batting for a single innings of 20 overs (each \"over\" being a set of 6 fair opportunities for the batting team to score) and the game generally lasting three hours, to Test matches played over five days. Traditionally cricketers play in all-white kit, but in limited overs cricket they wear club or team colours. In addition to the basic kit, some players wear protective gear to prevent injury caused by the ball, which is a hard, solid spheroid made of compressed leather with a slightly raised sewn seam enclosing a cork core layered with tightly wound string.\n\nThe earliest reference to cricket is in South East England in the mid-16th century. It spread globally with the expansion of the British Empire, with the first international matches in the second half of the 19th century. The game's governing body is the International Cricket Council (ICC), which has over 100 members, twelve of which are full members who play Test matches. The game's rules, the Laws of Cricket, are maintained by Marylebone Cricket Club (MCC) in London. The sport is followed primarily in South Asia, Australasia, the United Kingdom, Southern Africa and the West Indies.\n\nWomen's cricket, which is organised and played separately, has also achieved international standard.

        "question": "In their method is the positional information for words in the sequence retained?",
        "answer": "Yes.",
        "evidence": "Words with multiple senses commonly exist in many languages. For example, the word bank can either mean a “financial establishment” or “the land alongside or sloping down to a river or lake”, based on different contexts. Such a word is called a “polyseme”. The task to identify the meaning of a polyseme in its surrounding context is called word sense disambiguation (WSD). Word sense disambiguation is a long-standing problem in natural language processing (NLP), and has broad applications in other NLP problems such as machine translation BIBREF0 . Lexical sample task and all-word task are the two main branches of WSD problem. The former focuses on only a pre-selected set of polysemes whereas the later intends to disambiguate every polyseme in the entire text. Numerous works have been devoted in WSD task, including supervised, unsupervised, semi-supervised and knowledge based learning BIBREF1 . Our work focuses on using supervised learning to solve all-word WSD problem.\nMost supervised approaches focus on extracting features from words in the context. Early approaches mostly depend on hand-crafted features. For example, IMS by BIBREF2 uses POS tags, surrounding words and collections of local words as features. These approaches are later improved by combining with word embedding features BIBREF0 , which better represents the words' semantic information in a real-value space. However, these methods neglect the valuable positional information between the words in the sequence BIBREF3 . The bi-directional Long-Short-Term-Memory (LSTM) approach by BIBREF3 provides one way to leverage the order of words. Recently, BIBREF4 improved the performance by pre-training a LSTM language model with a large unlabelled corpus, and using this model to generate sense vectors for further WSD predictions. However, LSTM significantly increases the computational complexity during the training process.\nThe development of the so called “fixed-size ordinally forgetting encoding” (FOFE) has enabled us to consider more efficient method. As firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence. FOFE has been applied to several NLP problems in the past, such as language model BIBREF5 , named entity recognition BIBREF6 , and word embedding BIBREF7 . The promising results demonstrated by the FOFE approach in these areas inspired us to apply FOFE in solving the WSD problem. In this paper, we will first describe how FOFE is used to encode sequence of any length into a fixed-size representation. Next, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data. Lastly, we provide the experiment results of our method on several WSD data sets to justify the equivalent performance as the state-of-the-art approach.\nAs firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence.",

        "evidence": "Machine reading comprehension and question answering has becomes a crucial application problem in evaluating the progress of AI system in the realm of natural language processing and understanding BIBREF0 . The computational linguistics communities have devoted significant attention to the general problem of machine reading comprehension and question answering.\nHowever, most of existing reading comprehension tasks only focus on shallow QA tasks that can be tackled very effectively by existing retrieval-based techniques BIBREF1 . For example, recently we have seen increased interest in constructing extractive machine reading comprehension datasets such as SQuAD BIBREF2 and NewsQA BIBREF3 . Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively.

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously.",

        "answer": "No.",
        "evidence": "Until recently, efforts to bring out semantics from structured-data relied heavily on expert knowledge BIBREF22, BIBREF8. For example, in order to better transcribe numerical time series of weather data to a textual forecast, Reiter et al. BIBREF8 devise complex template schemes in collaboration with weather experts to build a consistent set of data-to-word rules.\nModern approaches to the wide range of tasks based on structured-data (e.g. table retrieval BIBREF2, BIBREF23, table classification BIBREF24, question answering BIBREF25) now propose to leverage progress in deep learning to represent these data into a semantic vector space (also called embedding space). In parallel, an emerging task, called “data-to-text\", aims at describing structured data into a natural language description. This task stems from the neural machine translation (NMT) domain, and early work BIBREF26, BIBREF27, BIBREF10 represent the data records as a single sequence of facts to be entirely translated into natural language. Wiseman et al. BIBREF10 show the limits of traditional NMT systems on larger structured-data, where NMT systems fail to accurately extract salient elements.\nTo improve these models, a number of work BIBREF28, BIBREF12, BIBREF29 proposed innovating decoding modules based on planning and templates, to ensure factual and coherent mentions of records in generated descriptions. For example, Puduppully et al. BIBREF12 propose a two-step decoder which first targets specific records and then use them as a plan for the actual text generation. Similarly, Li et al. BIBREF28 proposed a delayed copy mechanism where their decoder also acts in two steps: 1) using a classical LSTM decoder to generate delexicalized text and 2) using a pointer network BIBREF30 to replace placeholders by records from the input data.\nCloser to our work, very recent work BIBREF11, BIBREF19, BIBREF13 have proposed to take into account the data structure. More particularly, Puduppully et al. BIBREF13 follow entity-centric theories BIBREF31, BIBREF32 and propose a model based on dynamic entity representation at decoding time. It consists in conditioning the decoder on entity representations that are updated during inference at each decoding step. On the other hand, Liu et al. BIBREF11, BIBREF19 rather focus on introducing structure into the encoder. For instance, they propose a dual encoder BIBREF19 which encodes separately the sequence of element names and the sequence of element values. These approaches are however designed for single-entity data structures and do not account for delimitation between entities.\nOur contribution differs from previous work in several aspects. First, instead of flatly concatenating elements from the data-structure and encoding them as a sequence BIBREF11, BIBREF12, BIBREF10, we constrain the encoding to the underlying structure of the input data, so that the delimitation between entities remains clear throughout the process. Second, unlike all works in the domain, we exploit the Transformer architecture BIBREF21 and leverage its particularity to directly compare elements with each others in order to avoid arbitrary assumptions on their ordering. Finally, in contrast to BIBREF33, BIBREF13 that use a complex updating mechanism to obtain a dynamic representation of the input data and its entities, we argue that explicit hierarchical encoding naturally guides the decoding process via hierarchical attention.\n\nOn the other hand, Liu et al. [18,17] rather focus on introducing structure into the encoder. For instance, they propose a dual encoder [17] which encodes separately the sequence of element names and the sequence of element values.

While aspects of their production can induce similar, less or alternative environmental impacts, they produce little or no tailpipe emissions, and reduce dependence on petroleum, greenhouse gas emissions, and health effects from air pollution. Electric motors are significantly more efficient than internal combustion engines and thus, even accounting for typical power plant efficiencies and distribution losses, less energy is required to operate an EV. Manufacturing batteries for electric cars requires additional resources and energy, so they may have a larger environmental footprint from the production phase. EVs also generate different impacts in their operation and maintenance. EVs are typically heavier and could produce more tire and road dust air pollution, but their regenerative braking could reduce such particulate pollution from brakes. EVs are mechanically simpler, which reduces the use and disposal of engine oil.",
        "answer": "Although all cars have effects on other people, battery electric cars have major environmental benefits over conventional internal combustion engine vehicles (ICEVs), such as:\n\nElimination of harmful tailpipe pollutants such as various oxides of nitrogen, which kill thousands of people every year. EVs use 38 megajoules per 100 km in comparison to 142 megajoules per 100 km for ICE cars. Less CO2 emissions globally than fossil-fuelled cars, thus limiting climate change.  Plug-in hybrids capture most of these benefits when they are operating in all-electric mode.\n\nElectric cars have some disadvantages, such as:\n\nPossible increased particulate matter emissions from tires compared to fossil-fueled cars. This is sometimes caused by the fact that most electric cars have a heavy battery, which means the car's tires are subjected to more wear. This is drastically reduced when EV-rated weight-specific tires are used on the EV which are built specifically for the extra weight.[citation needed] Devices to capture tyre particulates are being developed.\nThe brake pads, however, can be used less frequently than in non-electric cars, if regenerative braking is available and may thus sometimes produce less particulate pollution than brakes in non-electric cars. Also, some electric cars may have a combination of drum brakes and disc brakes, and drum brakes are known to cause less particulate emissions than disc brakes.\n\nReliance on rare-earth elements such as neodymium, lanthanum, terbium, and dysprosium, and other critical metals such as lithium and cobalt,though the quantity of rare metals used differs per car.

        "question": "How to find the optimal transformation matrix?",
        "answer": "Use normal equation.",
        "evidence": "As already stated, our main proposal is using neural embedding models to `project' documents in one language into the semantic space of another language. For this, we first trained a Continuous Bag-of-Words (CBOW) and a Continuous SkipGram model BIBREF0 for each of our monolingual subcorpora. The models were trained with identical hyperparameters: vector size of 300 components, symmetric window of 2 words, negative sampling with 10 samples, 5 iterations over the corpus, no down-sampling. The only language-dependent difference was that for the Ukrainian model we ignored words with the corpus frequency less than 10 and for the Russian model this threshold was set to 15 (as the Russian corpus is 3 times larger). All in all, the final Ukrainian model recognizes 429 215 words and the Russian one 271 720 words. Training was performed using CBOW and SkipGram implementation in Gensim library BIBREF7 .\nAfter the models were trained, we followed the path outlined in BIBREF4 to learn a linear transformation matrix from Ukrainian to Russian. First, we extracted all noun pairs from Russian-Ukrainian bilingual dictionary BIBREF8 , with the constraint that their frequency in our corpora was above the already mentioned thresholds 15 and 10 for Russian and Ukrainian words correspondingly. That made it a list of about 5 thousand pairs of nouns being translations of each other.\nFor all these words, their vectors were found in the models corresponding to the words' languages. It provided us with a matrix of 5 thousand of 300-dimensional Ukrainian vectors and the matrix of corresponding 5 thousand of 300-dimensional Russian vectors. This data served as a training set to learn an optimal transformation matrix. The latter is actually a 300x301 matrix of coefficients, such that when the initial Ukrainian matrix is multiplied by this transformation matrix, the result is maximally close to the corresponding Russian matrix. This transformation matrix has 301 (not 300) columns, because we add one component equal to 1 to each vector, as a bias term.\nProducing the transformation matrix is a linear regression problem: the input is 301 components of Ukrainian vectors (including the bias term) and the output is 300 components of Russian vectors. As we need 300 values as an output, there are actually 300 linear regression problems and that's why the resulting matrix size is 300x301 (301 weights for each of 300 components).\nThere are two main ways to solve a linear regression problem: one can either learn the optimal weights in an iterative way using some variant of gradient descent, or one can solve it numerically without iteration, using normal equation. For English and Spanish, BIBREF4 used stochastic gradient descent. However, normal equation is actually less error-prone and is guaranteed to find the global optimum. Its only disadvantage is that it becomes very computationally expensive when the number of features is large (thousands and more). However, in our case the number of features is only 301, so computational complexity is not an issue.\nThus, we use normal equation to find the optimal transformation matrix. The algebraic solution to each of 300 normal equations (one for each vector component $i$ ) is shown in the Equation 3 : \n$$\\beta _i = (\\textbf {X}^\\intercal * \\textbf {X})^{-1} * \\textbf {X}^\\intercal * y_i$$   (Eq. 3) \nwhere $\\textbf {X}$ is the matrix of 5 thousand Ukrainian word vectors (input), $y_i$ is the vector of the $i$ th components of 5 thousand corresponding Russian words (correct predictions), and $\\beta _i$ is our aim: the vector of 301 optimal coefficients which transform the Ukrainian vectors into the $i$ th component of the Russian vectors.\nAfter solving such normal equations for all the 300 components $i$ , we have the 300x301 linear transformation matrix which fits the data best.\nThis matrix basically maps the Ukrainian vectors into the Russian ones. It is based on the assumption that the relations between semantic concepts in different languages are in fact very similar (students are close to teachers, while pirates are close to corsairs, and so on). In continuous distributional models which strive to represent these semantic spaces, mutual `geometrical' relations between vectors representing particular words are also similar across models (if they are trained on comparable corpora), but the exact vectors for words denoting one and the same notion are different. This is because the models themselves are stochastic and the particular values of vectors (unlike their positions in relation to each other) depend a lot on technical factors, including the random seed used to initialize vectors prior to training. In order to migrate from a model A to another model B, one has to `rotate and scale' A vectors in a uniform linear way. To learn the optimal transformation matrix means to find out the exact directions of rotating and scaling, which minimize prediction errors.\nLinguistically speaking, once we learned the transformation matrix, we can predict what a Russian vector would most probably be, given a Ukrainian one. This essentially means we are able to `translate' Ukrainian words into Russian, by calculating the word in the Russian model with the vector closest to the predicted one.\nWe had to choose between CBOW or Continuous SkipGram models to use when learning the transformation matrix. Also, there was a question of whether to employ regularized or standard normal equations. Regularization is an attempt to avoid over-fitting by trying to somehow decrease the values of learned weights. The regularized normal equation is shown in 4 : \n$$\\beta _i = (\\textbf {X}^\\intercal * \\textbf {X} + \\lambda * L)^{-1} * \\textbf {X}^\\intercal * y_i$$   (Eq. 4) \nComparing to 3 , it adds the term $\\lambda * L$ , where $L$ is the identity matrix of the size equal to the number of features, with 0 at the top left cell, and $\\lambda $ is a real number used to tune the influence of regularization term (if $\\lambda = 0$ , there is no regularization).\nTo test all the possible combinations of parameters, we divided the bilingual dictionary into 4500 noun pairs used as a training set and 500 noun pairs used as a test set. We then learned transformation matrices on the training set using both training algorithms (CBOW and SkipGram) and several values of regularization $\\lambda $ from 0 to 5, with a step of 0.5. The resulting matrices were applied to the Ukrainian vectors from the test set and the corresponding Russian `translations' were calculated. The ratio of correct `translations' (matches) was used as an evaluation measure. It came out that regularization only worsened the results for both algorithms, so in the Table 1 we report the results without regularization.\nFor reference, we also report the accuracy of `quazi-translation' via Damerau-Levenshtein edit distance BIBREF9 , as a sort of a baseline. As already stated, the two languages share many cognates, and a lot of Ukrainian words can be orthographically transformed into their Russian translations (and vice versa) by one or two character replacements. Thus, we extracted 50,000 most frequent nouns from our Russian corpora; then for each Ukrainian noun in the bilingual dictionary we found the closest Russian noun (or 5 closest nouns for @5 metric) by edit distance and calculated how often it turned out to be the correct translation. As the Table 1 shows, notwithstanding the orthographic similarity of the two languages, CBOW consistently outperforms this approach even on the test set. On the training set, its superiority is even more obvious.\nThus, we use normal equation to find the optimal transformation matrix.",

It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south.

This eucalypt diet has low nutritional and caloric content and contains toxins that deter most other mammals from feeding on it. Koalas are largely sedentary and sleep up to twenty hours a day. They are asocial animals, and bonding exists only between mothers and dependent offspring. Adult males communicate with loud bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Being marsupials, koalas give birth to underdeveloped young that crawl into their mothers' pouches, where they stay for the first six to seven months of their lives.

        "question": "What does current consist of?",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

        "evidence": "Semantic Role Labeling (SRL) has emerged as an important task in Natural Language Processing (NLP) due to its applicability in information extraction, question answering, and other NLP tasks. SRL is the problem of finding predicate-argument structure in a sentence, as illustrated below:\n INLINEFORM0 \nHere, the predicate WRITE has two arguments: `Mike' as A0 or the writer, and `a book' as A1 or the thing written. The labels A0 and A1 correspond to the PropBank annotations BIBREF0 .\nAs the need for SRL arises in different domains and languages, the existing manually annotated corpora become insufficient to build supervised systems. This has motivated work on unsupervised SRL BIBREF1 , BIBREF2 , BIBREF3 . Previous work has indicated that unsupervised systems could benefit from the word alignment information in parallel text in two or more languages BIBREF4 , BIBREF5 , BIBREF6 . For example, consider the German translation of sentence INLINEFORM0 :\n INLINEFORM0 \nIf sentences INLINEFORM0 and INLINEFORM1 have the word alignments: Mike-Mike, written-geschrieben, and book-Buch, the system might be able to predict A1 for Buch, even if there is insufficient information in the monolingual German data to learn this assignment. Thus, in languages where the resources are sparse or not good enough, or the distributions are not informative, SRL systems could be made more accurate by using parallel data with resource rich or more amenable languages.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages. The model consists of individual Bayesian models for each language BIBREF3 , and crosslingual latent variables to incorporate soft role agreement between aligned constituents. This latent variable approach has been demonstrated to increase the performance in a multilingual unsupervised part-of-speech tagging model based on HMMs BIBREF4 . We investigate the application of this approach to unsupervised SRL, presenting the performance improvements obtained in different settings involving labeled and unlabeled data, and analyzing the annotation effort required to obtain similar gains using labeled data.\nWe begin by briefly describing the unsupervised SRL pipeline and the monolingual semantic role induction model we use, and then describe our multilingual model.\nThe model consists of individual Bayesian models for each language (Garg and Henderson, 2012), and crosslingual latent variables to incorporate soft role agreement between aligned constituents.",

        "question": "How to estimate the Individual SES?",
        "answer": "Individual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations.",
        "evidence": "Online social networks have become one of the most disruptive communication platforms, as everyday billions of individuals use them to interact with each other. Their penetration in our everyday lives seems ever-growing and has in turn generated a massive volume of publicly available data open to analysis. The digital footprints left across these multiple media platforms provide us with a unique source to study and understand how the linguistic phenotype of a given user is related to social attributes such as socioeconomic status (SES).\nThe quantification and inference of SES of individuals is a long lasting question in the social sciences. It is a rather difficult problem as it may depend on a combination of individual characteristics and environmental variables BIBREF0 . Some of these features can be easier to assess like income, gender, or age whereas others, relying to some degree on self-definition and sometimes entangled with privacy issues, are harder to assign like ethnicity, occupation, education level or home location. Furthermore, individual SES correlates with other individual or network attributes, as users tend to build social links with others of similar SES, a phenomenon known as status homophily BIBREF1 , arguably driving the observed stratification of society BIBREF2 . At the same time, shared social environment, similar education level, and social influence have been shown to jointly lead socioeconomic groups to exhibit stereotypical behavioral patterns, such as shared political opinion BIBREF3 or similar linguistic patterns BIBREF4 . Although these features are entangled and causal relation between them is far from understood, they appear as correlations in the data.\nDatasets recording multiple characteristics of human behaviour are more and more available due to recent developments in data collection technologies and increasingly popular online platforms and personal digital devices. The automatic tracking of online activities, commonly associated with profile data and meta-information; the precise recording of daily activities, interaction dynamics and mobility patterns collected through mobile personal devices; together with the detailed and expert annotated census data all provide new grounds for the inference of individual features or behavioral patterns BIBREF5 . The exploitation of these data sources has already been proven to be fruitful as cutting edge recommendation systems, advanced methods for health record analysis, or successful prediction tools for social behaviour heavily rely on them BIBREF6 . Nevertheless, despite the available data, some inference tasks, like individual SES prediction, remain an open challenge.\nThe precise inference of SES would contribute to overcome several scientific challenges and could potentially have several commercial applications BIBREF7 . Further, robust SES inference would provide unique opportunities to gain deeper insights on socioeconomic inequalities BIBREF8 , social stratification BIBREF2 , and on the driving mechanisms of network evolution, such as status homophily or social segregation.\nIn this work, we take a horizontal approach to this problem and explore various ways to infer the SES of a large sample of social media users. We propose different data collection and combination strategies using open, crawlable, or expert annotated socioeconomic data for the prediction task. Specifically, we use an extensive Twitter dataset of 1.3M users located in France, all associated with their tweets and profile information; 32,053 of them having inferred home locations. Individual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations. Each of these datasets is then used as ground-truth to infer the SES of Twitter users from profile and semantic features similar to BIBREF9 . We aim to explore and assess how the SES of social media users can be obtained and how much the inference problem depends on annotation and the user's individual and linguistic attributes.\nWe provide in Section SECREF2 an overview of the related literature to contextualize the novelty of our work. In Section SECREF3 we provide a detailed description of the data collection and combination methods. In Section SECREF4 we introduce the features extracted to solve the SES inference problem, with results summarized in Section SECREF5 . Finally, in Section SECREF6 and SECREF7 we conclude our paper with a brief discussion of the limitations and perspectives of our methods.\nIndividual SES is estimated by relying on three separate datasets, namely socioeconomic census data; crawled profession information and expert annotated Google Street View images of users' home locations.",

        "evidence": "The proliferation of the online social media has lately resulted in the democratization of online content sharing. Among other media, Twitter is very popular for research and application purposes due to its scale, representativeness and ease of public access to its content. However, tweets, that are short messages of up to 140 characters, pose several challenges to traditional Natural Language Processing (NLP) systems due to the creative use of characters and punctuation symbols, abbreviations ans slung language.\nNamed Entity Recognition (NER) is a fundamental step for most of the information extraction pipelines. Importantly, the terse and difficult text style of tweets presents serious challenges to NER systems, which are usually trained using more formal text sources such as newswire articles or Wikipedia entries that follow particular morpho-syntactic rules. As a result, off-the-self tools trained on such data perform poorly BIBREF0 . The problem becomes more intense as the number of entities to be identified increases, moving from the traditional setting of very few entities (persons, organization, time, location) to problems with more. Furthermore, most of the resources (e.g., software tools) and benchmarks for NER are for text written in English. As the multilingual content online increases, and English may not be anymore the lingua franca of the Web. Therefore, having resources and benchmarks in other languages is crucial for enabling information access worldwide.\nIn this paper, we propose a new benchmark for the problem of NER for tweets written in French. The tweets were collected using the publicly available Twitter API and annotated with 13 types of entities. The annotators were native speakers of French and had previous experience in the task of NER. Overall, the generated datasets consists of INLINEFORM0 tweets, split in training and test parts.\nThe paper is organized in two parts. In the first, we discuss the data preparation steps (collection, annotation) and we describe the proposed dataset. The dataset was first released in the framework of the CAp 2017 challenge, where 8 systems participated. Following, the second part of the paper presents an overview of baseline systems and the approaches employed by the systems that participated. We conclude with a discussion of the performance of Twitter NER systems and remarks for future work.\nThe tweets were collected using the publicly available Twitter API and annotated with 13 types of entities.",

        "evidence": "The ability of semantic reasoning is essential for advanced natural language understanding (NLU) systems. Many NLU tasks that take sentence pairs as input, such as natural language inference (NLI) and machine reading comprehension (MRC), heavily rely on the ability of sophisticated semantic reasoning. For instance, the NLI task aims to determine whether the hypothesis sentence (e.g., a woman is sleeping) can be inferred from the premise sentence (e.g., a woman is talking on the phone). This requires the model to read and understand sentence pairs to make the specific semantic inference.\nBidirectional Encoder Representations from Transformer (BERT) BIBREF1 has shown strong ability in semantic reasoning. It was recently proposed and obtained impressive results on many tasks, ranging from text classification, natural language inference, and machine reading comprehension. BERT achieves this by employing two objectives in the pre-training, i.e., the masked language modeling (Masked LM) and the next sentence prediction (NSP). Intuitively, the Masked LM task concerns word-level knowledge, and the NSP task captures the global document-level information. The goal of NSP is to identify whether an input sentence is next to another input sentence. From the ablation study BIBREF1, the NSP task is quite useful for the downstream NLI and MRC tasks (e.g., +3.5% absolute gain on the Question NLI (QNLI) BIBREF2 task).\nDespite its usefulness, we suggest that BERT has not made full use of the document-level knowledge. The sentences in the negative samples used in NSP are randomly drawn from other documents. Therefore, to discriminate against these sentences, BERT is prone to aggregating the shallow semantic, e.g., topic, neglecting context clues useful for detailed reasoning. In other words, the canonical NSP task would encourage the model to recognize the correlation between sentences, rather than obtaining the ability of semantic entailment. This setting weakens the BERT model from learning specific semantic for inference. Another issue that renders NSP less effective is that BERT is order-sensitive. Performance degradation was observed on typical NLI tasks when the order of two input sentences are reversed during the BERT fine-tuning phase. It is reasonable as the NSP task can be roughly analogy to the NLI task when the input comes as (premise, hypothesis), considering the causal order among sentences. However, this identity between NSP and NLI is compromised when the sentences are swapped.\nBased on these considerations, we propose a simple yet effective method, i.e., introducing a IsPrev category to the classification task, which is a symmetric label of IsNext of NSP. The input of samples with IsPrev is the reverse of those with IsNext label. The advantages of using this previous sentence prediction (PSP) are three folds. (1) Learning the contrast between NSP and PSP forces the model to extract more detailed semantic, thereby the model is more capable of discriminating the correlation and entailment. (2) NSP and PSP are symmetric. This symmetric regularization alleviates the influence of the order of the input pair. (3) Empirical results indicate that our method is beneficial for all the semantic reasoning tasks that take sentence pair as input.\nIn addition, to further incorporating the document-level knowledge, NSP and PSP are extended with non-successive sentences, where the label smoothing technique is adopted. The proposed method yields a considerable improvement in our experiments. We evaluate the ability of semantic reasoning on standard NLI and MRC benchmarks, including the challenging HANS dataset BIBREF0. Analytical work on the HANS dataset provides a more comprehensible perspective towards the proposed method. Furthermore, the results on the Chinese benchmarks are provided to demonstrate its generality.\nIn summary, this work makes the following contributions:\nThe supervision signal from the original NSP task is weak for semantic inference. Therefore, a novel method is proposed to remedy the asymmetric issue and enhance the reasoning ability.\nBoth empirical and analytical evaluations are provided on the NLI and MRC datasets, which verifies the effectiveness of using more document-level knowledge.\nWe evaluate the ability of semantic reasoning on standard NLI and MRC benchmarks, including the challenging HANS dataset.",

The musical starts with a press conference, where Keane explains his proof to reporters and promises to return to normal life with his wife Anna and his family. After promising to Anna that he is now \"done with Fermat\", Keane is surprised in his study by none other than Fermat himself. Keane asks Fermat for the secret of his proof but is refused. Instead, Fermat introduces him to the \"Aftermath\", a \"heavenly purgatory\" where he meets the famous mathematicians Euclid, Pythagoras, Newton, and Gauss.

Keane returns to his attic to try to fix his proof, while his \"math widow\" wife is frustrated.

        "answer": "n-gram embedding.",
        "evidence": "Automatic summarization, machine translation, question answering, and semantic parsing operations are useful for processing, analyzing, and extracting meaningful information from text. However, when applied to long texts, these tasks usually require some minimal syntactic structure to be identified, such as sentences BIBREF0 , BIBREF1 , BIBREF2 , which always end with a period (“.”) in English BIBREF3 .\nHowever, written Thai does not use an explicit end-of-sentence marker to identify sentence boundaries BIBREF4 . Prior works have adapted traditional machine learning models to predict the beginning position of a sentence. The authors of BIBREF5 , BIBREF6 , BIBREF7 proposed traditional models to determine whether a considered space is a sentence boundary based on the words and their part of speech (POS) near the space. Meanwhile, Zhou N. et al. BIBREF8 considered Thai sentence segmentation as a sequence tagging problem and proposed a CRF-based model with n-gram embedding to predict which word is the sentence boundary. This method achieves the state-of-the-art result for Thai sentence segmentation and achieves greater accuracy than other models by approximately 10% on an Orchid dataset BIBREF9 .\nSeveral deep learning approaches have been applied in various tasks of natural language processing (NLP), including the long short-term memory BIBREF10 , self-attention BIBREF11 , and other models. Huang Z. et al. BIBREF12 proposed a deep learning sequence tagging model called Bi-LSTM-CRF, which integrates a conditional random field (CRF) module to gain the benefit of both deep learning and traditional machine learning approaches. In their experiments, the Bi-LSTM-CRF model achieved an improved level of accuracy in many NLP sequence tagging tasks, such as named entity recognition, POS tagging and chunking.\nThe CRF module achieved the best result on the Thai sentence segmentation task BIBREF8 ; therefore, we adopt the Bi-LSTM-CRF model as our baseline. This paper makes the following three contributions to improve Bi-LSTM-CRF for sentence segmentation.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in BIBREF8 and BIBREF12 . By including n-gram embedding, the model can capitalize on both approaches. First, the model gains the ability to extract past and future input features and sentence level tag information from Bi-LSTM-CRF; moreover, with the n-gram addition, it can also extract a local representation from n-gram embedding, which helps in capturing word groups that exist near sentence boundary. Although Jacovi A. et al. BIBREF13 reported that a convolutional neural network (CNN) can be used as an n-gram detector to capture local features, we chose n-gram embedding over a CNN due to its better accuracy, as will be shown in Section SECREF8 .\nSecond, we propose adding incorporative distant representation into the model via a self-attention mechanism, which can focus on the keywords of dependent clauses that are far from the considered word. Self-attention has been used in many recent state-of-the-art models, most notably the transformer BIBREF11 and BERT BIBREF14 . BERT has outperformed Bi-LSTM on numerous tasks, including question answering and language inference. Therefore, we choose to use self-attention modules to extract distant representations along with local representations to improve model accuracy.\nThird, we also apply semi-supervised learning BIBREF15 , allowing us to employ unlimited amounts of unlabeled data, which is particularly important for low-resource languages such as Thai, for which annotation is costly and time-consuming. Many semi-supervised learning approaches have been proposed in the computer vision BIBREF16 , BIBREF17 and natural language processing BIBREF18 , BIBREF19 , BIBREF20 fields. Our choice for semi-supervised learning to enhance model representation is Cross-View Training (CVT) BIBREF20 . Clark K. et al. BIBREF20 claims that CVT can improve the representation layers of the model, which is our goal. However, CVT was not designed to be integrated with self-attention and CRF modules; consequently, we provide a modified version of CVT in this work.\nBased on the above three contributions, we pursue two main experiments. The first experiment was conducted on two Thai datasets, Orchid and UGWC BIBREF21 , to evaluate our Thai sentence segmentation model. In this case, our model achieves F1 scores of 92.5% and 88.9% on Orchid and UGWC, respectively, and it outperforms all the baseline models. The second experiment was executed on the IWSLT dataset BIBREF22 and involves an English-language punctuation restoration task. This experiment demonstrates that our model is generalizable to different languages. Our model, which does not require pretrained word vectors, improved the overall F1 score by 0.9% compared to the baselines, including a model that uses pretrained word vectors.\nThere are five sections in the remainder of this paper. Section SECREF2 reviews the related works on Thai sentence segmentation, English punctuation restoration and introduces the original CVT. Section SECREF3 describes the proposed model architecture and the integration of cross-view training. The datasets, implementation process and evaluation metrics are explained in Section SECREF4 . The results of the experiments are discussed in Section SECREF5 . Finally, Section SECREF6 concludes the paper.\nFirst, we propose adding n-gram embedding to Bi-LSTM-CRF due to its success in and .",

        "answer": "The crowdsourcing could be used as one alternative way at lower cost in a short time.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time.",

Its goal is to present statistical analyses of issues of clinical focus based on retrieving and analyzing numerous papers in the medical literature BIBREF0 . The PubMed database is one of the most commonly used databases in EBM BIBREF1 .\nBiomedical papers, describing randomized controlled trials in medical intervention, are published at a high rate every year. The volume of these publications makes it very challenging for physicians to find the best medical intervention for a given patient group and condition BIBREF2 . Computational methods and natural language processing (NLP) could be adopted in order to expedite the process of biomedical evidence synthesis. Specifically, NLP tasks applied to well structured documents and queries can help physicians extract appropriate information to identify the best available evidence in the context of medical treatment.\nClinical questions are formed using the PIO framework, where clinical issues are broken down into four components: Population/Problem (P), Intervention (I), Comparator (C), and Outcome (O). We will refer to these categories as PIO elements, by using the common practice of merging the C and I categories. In BIBREF3 a literature screening performed in 10 systematic reviews was studied. It was found that using the PIO framework can significantly improve literature screening efficacy. Therefore, efficient extraction of PIO elements is a key feature of many EBM applications and could be thought of as a multi-label sentence classification problem.\nPrevious works on PIO element extraction focused on classical NLP methods, such as Naive Bayes (NB), Support Vector Machines (SVM) and Conditional Random Fields (CRF) BIBREF4 , BIBREF5 . These models are shallow and limited in terms of modeling capacity. Furthermore, most of these classifiers are trained to extract PIO elements one by one which is sub-optimal since this approach does not allow the use of shared structure among the individual classifiers.\nDeep neural network models have increased in popularity in the field of NLP. They have pushed the state of the art of text representation and information retrieval. More specifically, these techniques enhanced NLP algorithms through the use of contextualized text embeddings at word, sentence, and paragraph levels BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 .\nMore recently, jin2018pico proposed a bidirectional long short term memory (LSTM) model to simultaneously extract PIO components from PubMed abstracts. To our knowledge, that study was the first in which a deep learning framework was used to extract PIO elements from PubMed abstracts.\nIn the present paper, we build a dataset of PIO elements by improving the methodology found in BIBREF12 . Furthermore, we built a multi-label PIO classifier, along with a boosting framework, based on the state of the art text embedding, BERT. This embedding model has been proven to offer a better contextualization compared to a bidirectional LSTM model BIBREF9 .\nIn the present paper, we build a dataset of PIO elements by improving the methodology found in (Jin and Szolovits, 2018).",

        "evidence": "End-to-end speech translation aims to translate a piece of audio into a target-language translation in one step. The raw speech signals are usually converted to sequences of acoustic features, e.g. Mel filterbank features. Here, we define the speech feature sequence as $\\mathbf {x} = (x_1, \\cdots , x_{T_x})$.The transcription and translation sequences are denoted as $\\mathbf {y^{s}} = (y_1^{s}, \\cdots , y_{T_s}^{s})$, and $\\mathbf {y^{t}} = (y_1^{t}, \\cdots , y_{T_t}^{t})$ repectively. Each symbol in $\\mathbf {y^{s}}$ or $\\mathbf {y^{t}}$ is an integer index of the symbol in a vocabulary $V_{src}$ or $V_{trg}$ respectively (e.g. $y^s_i=k, k\\in [0, |V_{src}|-1]$). In this work, we suppose that an ASR dataset, an MT dataset, and a ST dataset are available, denoted as $\\mathcal {A} = \\lbrace (\\mathbf {x_i}, \\mathbf {y^{s}_i})\\rbrace _{i=0}^I$, $\\mathcal {M} =\\lbrace (\\mathbf {y^{s}_j}, \\mathbf {y^{t}_j})\\rbrace _{j=0}^J$ and $ \\mathcal {S} =\\lbrace (\\mathbf {x_l}, \\mathbf {y^{t}_l})\\rbrace _{l=0}^L$ respectively. Given a new piece of audio $\\mathbf {x}$, our goal is to learn an end to end model to generate a translation sentence $\\mathbf {y^{t}}$ without generating an intermediate result $\\mathbf {y^{s}}$.\nTo leverage large scale ASR and MT data, multi-task learning and pre-training techniques are widely employed to improve the ST system. As shown in Figure FIGREF4, there are three popular multi-task strategies for ST, including 1) one-to-many setting, in which a speech encoder is shared between ASR and ST tasks; 2) many-to-one setting in which a decoder is shared between MT and ST tasks; and 3) many-to-many setting where both the encoder and decoder are shared.\nA many-to-many multi-task model contains two encoders as well as two decoders. It can be jointly trained on ASR, MT, and ST tasks. As the attention module is task-specific, three attentions are defined.\nUsually, the size of $\\mathcal {A}$ and $\\mathcal {M}$ is much larger than $\\mathcal {S}$. Therefore, the common training practice is to pre-train the model on ASR and MT tasks and then fine-tune it with a multi-task learning manner.

        "evidence": "\nThe goal of meeting transcription is to have machines generate speaker-annotated transcripts of natural meetings based on their audio and optionally video recordings. Meeting transcription and analytics would be a key to enhancing productivity as well as improving accessibility in the workplace. It can also be used for conversation transcription in other domains such as healthcare BIBREF0. Research in this space was promoted in the 2000s by NIST Rich Transcription Evaluation series and public release of relevant corpora BIBREF1, BIBREF2, BIBREF3. While systems developed in the early days yielded high error rates, advances have been made in individual component technology fields, including conversational speech recognition BIBREF4, BIBREF5, far-field speech processing BIBREF6, BIBREF7, BIBREF8, and speaker identification and diarization BIBREF9, BIBREF10, BIBREF11. When cameras are used in addition to microphones to capture the meeting conversations, speaker identification quality could be further improved thanks to the computer vision technology. These trends motivated us to build an end-to-end audio-visual meeting transcription system to identify and address unsolved challenges. This report describes our learning, with focuses on overall architecture design, overlapped speech recognition, and audio-visual speaker diarization.\nWhen designing meeting transcription systems, different constraints must be taken into account depending on targeted scenarios. In some cases, microphone arrays are used as an input device. If the names of expected meeting attendees are known beforehand, the transcription system should be able to provide each utterance with the true identity (e.g., “Alice” or “Bob”) instead of a randomly generated label like “Speaker1”. It is often required to show the transcription in near real time, which makes the task more challenging.\nThis work assumes the following scenario. We consider a scheduled meeting setting, where an organizer arranges a meeting in advance and sends invitations to attendees. The transcription system has access to the invitees' names. However, actual attendees may not completely match those invited to the meeting. The users are supposed to enroll themselves in the system beforehand so that their utterances in the meeting can be associated with their names. The meeting is recorded with an audio-visual device equipped with a seven-element circular microphone array and a fisheye camera. Transcriptions must be shown with a latency of up to a few seconds.\nThis paper investigates three key challenges.\n\nSpeech overlaps: Recognizing overlapped speech has been one of the main challenges in meeting transcription with limited tangible progress. Numerous multi-channel speech separation methods were proposed based on independent component analysis or spatial clustering BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. However, there was little successful effort to apply these methods to natural meetings. Neural network-based single-channel separation methods using techniques like permutation invariant training (PIT) BIBREF18 or deep clustering (DC) BIBREF19 are known to be vulnerable to various types of acoustic distortion, including reverberation and background noise BIBREF20. In addition, these methods were tested almost exclusively on small-scale segmented synthetic data and have not been applied to continuous conversational speech audio. Although the recently held CHiME-5 challenge helped the community make a step forward to a realistic setting, it still allowed the use of ground-truth speaker segments BIBREF21, BIBREF22.\nWe address this long-standing problem with a continuous speech separation (CSS) approach, which we proposed in our latest conference papers BIBREF23, BIBREF24. It is based on an observation that the maximum number of simultaneously active speakers is usually limited even in a large meeting. According to BIBREF25, two or fewer speakers are active for more than 98% of the meeting time. Thus, given continuous multi-channel audio observation, we generate a fixed number, say $N$, of time-synchronous signals. Each utterance is separated from overlapping voices and background noise. Then, the separated utterance is spawned from one of the $N$ output channels. For periods where the number of active speakers is fewer than $N$, the extra channels generate zeros. We show how continuous speech separation can fit in with an overall meeting transcription architecture to generate speaker-annotated transcripts.\nNote that our speech separation system does not make use of a camera signal. While much progress has been made in audio-visual speech separation, the challenge of dealing with all kinds of image variations remains unsolved BIBREF26, BIBREF27, BIBREF28.\n\nExtensible framework: It is desirable that a single transcription system be able to support various application settings for both maintenance and scalability purposes. While this report focuses on the audio-visual setting, our broader work covers an audio-only setting as well as the scenario where no prior knowledge of meeting attendees is available. A modular and versatile architecture is desired to encompass these different settings.\nTo this end, we propose a framework called SRD, which stands for “separate, recognize, and diarize”, where CSS, speech recognition, and speaker diarization takes place in tandem. Performing CSS at the beginning allows the other modules to operate on overlap-free signals. Diarization is carried out after speech recognition because its implementation can vary significantly depending on the application settings. By choosing an appropriate diarization module for each setting, multiple use cases can be supported without changing the rest of the system. This architecture also allows transcriptions to be displayed in real time without speaker information. Speaker identities for each utterance may be shown after a couple of seconds.\n\nAudio-visual speaker diarization: Speaker diarization, a process of segmenting input audio and assigning speaker labels to the individual segments, can benefit from a camera signal. The phenomenal improvements that have been made to face detection and identification algorithms by convolutional neural networks (CNNs) BIBREF29, BIBREF30, BIBREF31 make the camera signal very appealing for speaker diarization. While much prior work assumes the batch processing scenario where the entire meeting recording can be processed multiple times, several studies deal with online processing BIBREF32, BIBREF33, BIBREF34, BIBREF35. However, no previous studies comprehensively address the challenges that one might encounter in real meetings. BIBREF32, BIBREF33 do not cope with speech overlaps. While the methods proposed in BIBREF34, BIBREF35 address the overlap issue, they rely solely on spatial cues and thus are not applicable when multiple speakers sit side by side.\nOur diarization method handles overlapping utterances as well as co-located speakers by utilizing the time-frequency (TF) masks generated by CSS in speaker identification and sound source localization (SSL). In addition, several enhancements are made to face identification to improve robustness to image variations caused by face occlusions, extreme head pose, lighting conditions, and so on.\nWe consider a scheduled meeting setting, where an organizer arranges a meeting in advance and sends invitations to attendees.",

        "evidence": "In photography, exposure value (EV) is a number that represents a combination of a camera's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance). Exposure value is also used to indicate an interval on the photographic exposure scale, with a difference of 1 EV corresponding to a standard power-of-2 exposure step, commonly referred to as a stop.\n\nThe EV concept was developed by the German shutter manufacturer Friedrich Deckel in the 1950s (Gebele 1958; Ray 2000, 318). Its intent was to simplify choosing among equivalent camera exposure settings by replacing combinations of shutter speed and f-number (e.g., 1/125 s at f/16) with a single number (e.g., 15). On some lenses with leaf shutters, the process was further simplified by allowing the shutter and aperture controls to be linked such that, when one was changed, the other was automatically adjusted to maintain the same exposure. This was especially helpful to beginners with limited understanding of the effects of shutter speed and aperture and the relationship between them. But it was also useful for experienced photographers who might choose a shutter speed to stop motion or an f-number for depth of field, because it allowed for faster adjustment—without the need for mental calculations—and reduced the chance of error when making the adjustment.",
        "answer": "If a DSLR camera is not set to 'Automatic' mode, there are 3 primary functions that need to be considered when deciding on the correct exposure for your image.\n1) the Aperture - how wide the aperture on the lens is set determines how much light can pass through the aperture. A small aperture (e.g. f/16) allows less light to reach the sensor as opposed to a wide aperture (e.g f/2.4).\n2) the Shutter Speed - how long the shutter is allowed to remain open after you depress the release on the camera. A short exposure time (e.g. 1/1000 sec) will allow less light to hit the cameras sensor whilst a long exposure (e.g. 1/4 sec) will let more light hit the sensor\n3) the ISO setting - this setting is used to control how sensitive the sensor is to light hitting it. A low ISO setting (e.g. ISO 200) is much less sensitive than a high ISO setting (e.g. ISO 1600) which means less light is required to capture the for the image on the sensor.\nAll 3 of these functions work in tandem to ensure the correct exposure value is created based on the image and effect you are trying to create.",

        "question": "Given this background text about the Byzantine Empire, which empire can the Byzantines trace their origins?",
        "evidence": "The Byzantine Empire,[note 1] also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms \"Byzantine Empire\" and \"Eastern Roman Empire\" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire and to themselves as Romans[note 2]—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome as it was centered on Constantinople instead of Rome, oriented towards Greek rather than Latin culture, and was characterized by Eastern Orthodox Christianity.\n\nDuring the high period of the Roman Empire known as the Pax Romana, the western parts of the empire went through Latinization, while the eastern parts of the empire maintained to a large degree their Hellenistic culture. Several events from the 4th to 6th centuries mark the period of transition during which the Roman Empire's Greek East and Latin West diverged. Constantine I (r. 324–337) reorganized the empire, made Constantinople the capital, and legalized Christianity. Under Theodosius I (r. 379–395), Christianity became the state religion, and other religious practices were proscribed. In the reign of Heraclius (r. 610–641), the empire's military and administration were restructured, and Greek was gradually adopted for official use in place of Latin.\n\nThe borders of the empire fluctuated through several cycles of decline and recovery. During the reign of Justinian I (r. 527–565), the empire reached its greatest extent after the fall of the west, re-conquering much of the historically Roman western Mediterranean coast, including Africa, Italy and Rome, which it held for two more centuries. The Byzantine–Sasanian War of 602–628 exhausted the empire's resources, and during the early Muslim conquests of the 7th century, it lost its richest provinces, Egypt and Syria, to the Rashidun Caliphate. It then lost Africa to the Umayyads in 698, before the empire was rescued by the Isaurian dynasty.\n\nDuring the Macedonian dynasty (9th–11th centuries), the empire expanded again and experienced the two-century-long Macedonian Renaissance, which came to an end with the defeat by Seljuk Turks at the Battle of Manzikert in 1071. Civil wars and the ensuing Seljuk invasion led to the loss of most of Asia Minor. The empire recovered during the Komnenian restoration, and by the 12th century, Constantinople was the largest and wealthiest city in Europe.\n\nThe empire was delivered a mortal blow during the Fourth Crusade when Constantinople was sacked in 1204 and the territories that the empire formerly governed were divided into competing Byzantine Greek and Latin realms. Despite the eventual recovery of Constantinople in 1261, the Byzantine Empire remained only one of several small rival states in the area for the final two centuries of its existence. Its remaining territories were progressively annexed by the Ottomans in the Byzantine–Ottoman wars over the 14th and 15th centuries.\n\nThe fall of Constantinople to the Ottoman Empire in 1453 marked the end of the Byzantine Empire. Refugees fleeing the city after its capture would settle in Italy and other parts of Europe, helping to ignite the Renaissance. The Empire of Trebizond was conquered eight years later when its eponymous capital surrendered to Ottoman forces after it was besieged in 1461. The last Byzantine rump state, the Principality of Theodoro, was conquered by the Ottomans in 1475. Arguments can be made that the fall of the Byzantine Empire to the Ottomans is one of several factors contributing to the end of the Middle Ages and the start of the early modern period.[not verified in body]",

        "answer": "Due to their learning to learn nature, yet without increasing the number of model's parameters.",
        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nThe results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters.",

        "evidence": "Following developing news stories is imperative to making real-time decisions on important political and public safety matters. Given the abundance of media providers and languages, this endeavor is an extremely difficult task. As such, there is a strong demand for automatic clustering of news streams, so that they can be organized into stories or themes for further processing. Performing this task in an online and efficient manner is a challenging problem, not only for newswire, but also for scientific articles, online reviews, forum posts, blogs, and microblogs.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream. In this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes. For example, for news articles, we would want to cluster them into related news stories.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. Our clustering approach is part of a larger media monitoring project to solve the problem of monitoring massive text and TV/Radio streams (speech-to-text). In particular, media monitors write intelligence reports about the most relevant events, and being able to search, visualize and explore news clusters assists in gathering more insight about a particular story. Since relevant events may be spawned from any part of the world (and from many multilingual sources), it becomes imperative to cluster news across different languages.\nIn terms of granularity, the type of story clusters we are interested in are the group of articles which, for example : (i) Narrate recent air-strikes in Eastern Ghouta (Syria); (ii) Describe the recent launch of Space X's Falcon Heavy rocket.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream.",

Participation consists of posting stories that can be seen by other users, voting stories and comments, and comments in the story's comment section, in the form of a forum. The forums are arranged in the form of a tree, allowing nested conversations, where the replies to a comment are its direct responses. We collected all comments in the stories' conversation in Reddit that were posted in August 2015. Since it is infeasible to manually annotate all of the comments, we process this dataset with the goal of extracting threads that involve suspected trolling attempts and the direct responses to them. To do so, we used Lucene to create an inverted index from the comments and queried it for comments containing the word “troll” with an edit distance of 1 in order to include close variations of this word, hypothesizing that such comments would be reasonable candidates of real trolling attempts. We did observe, however, that sometimes people use the word troll to point out that another user is trolling. Other times, people use the term to express their frustration about a particular user, but there is no trolling attempt. Yet other times people simply discuss trolling and trolls without actually observing one. Nonetheless, we found that this search produced a dataset in which 44.3% of the comments are real trolling attempts. Moreover, it is possible for commenters to believe that they are witnessing a trolling attempt and respond accordingly even where there is none due to misunderstanding. Therefore, the inclusion of comments that do not involve trolling would allow us to learn what triggers a user's interpretation of trolling when it is not present and what kind of response strategies are used.\nWe had two human annotators who were trained on snippets (i.e., (suspected trolling attempt, responses) pairs) taken from 200 conversations and were allowed to discuss their findings. After this training stage, we asked them to independently label the four aspects for each snippet. We recognize that this limited amount of information is not always sufficient to recover the four aspects we are interested in, so we give the annotators the option to discard instances for which they couldn't determine the labels confidently. The final annotated dataset consists of 1000 conversations composed of 6833 sentences and 88047 tokens.

Gravel bikes are great for covering offroad miles more efficiently and long days in the saddle both on road or offroad. However, the lack of any meaningful suspension means that or but a small amount of time off paths and more established trails will be hard work. Downcountry bikes will enable you to go on a wider range of terrain, inlcuding the ability to do trail riding (be very careful before trying to navigate downhill trails on a gravel bike!). However, downcountry bikes are usually heavier but the full suspension and geometry makes them less efficient compared to a gravel bike.",

Their type and frequency varies significantly, depending on the text type. Texts belonging to specific text type, which are to be selected for inclusion in a corpus must contain enough different named entities and references and they need to be freely available. When comparing legal documents such as laws, court decisions or administrative regulations, decisions are the best option. In laws and administrative regulations, the frequencies of person, location and organization are not high enough for NER experiments. Court decisions, on the other hand, include person, location, organization, references to law, other decision and regulation.\nCourt decisions from 2017 and 2018 were selected for the dataset, published online by the Federal Ministry of Justice and Consumer Protection. The documents originate from seven federal courts: Federal Labour Court (BAG), Federal Fiscal Court (BFH), Federal Court of Justice (BGH), Federal Patent Court (BPatG), Federal Social Court (BSG), Federal Constitutional Court (BVerfG) and Federal Administrative Court (BVerwG).\nFrom the table of contents, 107 documents from each court were selected (see Table ). The data was collected from the XML documents, i. e., it was extracted from the XML elements Mitwirkung, Titelzeile, Leitsatz, Tenor, Tatbestand, Entscheidungsgründe, Gründen, abweichende Meinung, and sonstiger Titel. The metadata at the beginning of the documents (name of court, date of decision, file number, European Case Law Identifier, document type, laws) and those that belonged to previous legal proceedings was deleted.

        "question": "Please give me a short bulleted list of the key components/architectures in a convolutional neural network.",
        "evidence": "A convolutional neural network consists of an input layer, hidden layers and an output layer. In any feed-forward neural network, any middle layers are called hidden because their inputs and outputs are masked by the activation function and final convolution. In a convolutional neural network, the hidden layers include layers that perform convolutions. Typically this includes a layer that performs a dot product of the convolution kernel with the layer's input matrix. This product is usually the Frobenius inner product, and its activation function is commonly ReLU. As the convolution kernel slides along the input matrix for the layer, the convolution operation generates a feature map, which in turn contributes to the input of the next layer. This is followed by other layers such as pooling layers, fully connected layers, and normalization layers.\n\nConvolutional layers\n\nConvolutional layers convolve the input and pass its result to the next layer. This is similar to the response of a neuron in the visual cortex to a specific stimulus. Each convolutional neuron processes data only for its receptive field. Although fully connected feedforward neural networks can be used to learn features and classify data, this architecture is generally impractical for larger inputs (e.g., high-resolution images), which would require massive numbers of neurons because each pixel is a relevant input feature. A fully connected layer for an image of size 100 × 100 has 10,000 weights for each neuron in the second layer. Convolution reduces the number of free parameters, allowing the network to be deeper. For example, using a 5 × 5 tiling region, each with the same shared weights, requires only 25 neurons. Using regularized weights over fewer parameters avoids the vanishing gradients and exploding gradients problems seen during backpropagation in earlier neural networks.\n\nTo speed processing, standard convolutional layers can be replaced by depthwise separable convolutional layers, which are based on a depthwise convolution followed by a pointwise convolution. The depthwise convolution is a spatial convolution applied independently over each channel of the input tensor, while the pointwise convolution is a standard convolution restricted to the use of \n\nPooling layers\nConvolutional networks may include local and/or global pooling layers along with traditional convolutional layers. Pooling layers reduce the dimensions of data by combining the outputs of neuron clusters at one layer into a single neuron in the next layer. Local pooling combines small clusters, tiling sizes such as 2 × 2 are commonly used. Global pooling acts on all the neurons of the feature map. There are two common types of pooling in popular use: max and average. Max pooling uses the maximum value of each local cluster of neurons in the feature map, while average pooling takes the average value.\n\nFully connected layers\nFully connected layers connect every neuron in one layer to every neuron in another layer. It is the same as a traditional multilayer perceptron neural network (MLP). The flattened matrix goes through a fully connected layer to classify the images.\n\nReceptive field\nIn neural networks, each neuron receives input from some number of locations in the previous layer. In a convolutional layer, each neuron receives input from only a restricted area of the previous layer called the neuron's receptive field. Typically the area is a square (e.g. 5 by 5 neurons). Whereas, in a fully connected layer, the receptive field is the entire previous layer. Thus, in each convolutional layer, each neuron takes input from a larger area in the input than previous layers. This is due to applying the convolution over and over, which takes into account the value of a pixel, as well as its surrounding pixels. When using dilated layers, the number of pixels in the receptive field remains constant, but the field is more sparsely populated as its dimensions grow when combining the effect of several layers.\n\nTo manipulate the receptive field size as desired, there are some alternatives to the standard convolutional layer. For example, atrous or dilated convolution expands the receptive field size without increasing the number of parameters by interleaving visible and blind regions. Moreover, a single dilated convolutional layer can comprise filters with multiple dilation ratios, thus having a variable receptive field size.\n\nWeights\nEach neuron in a neural network computes an output value by applying a specific function to the input values received from the receptive field in the previous layer. The function that is applied to the input values is determined by a vector of weights and a bias (typically real numbers). Learning consists of iteratively adjusting these biases and weights.\n\nThe vectors of weights and biases are called filters and represent particular features of the input (e.g., a particular shape). A distinguishing feature of CNNs is that many neurons can share the same filter. This reduces the memory footprint because a single bias and a single vector of weights are used across all receptive fields that share that filter, as opposed to each receptive field having its own bias and vector weighting.",

        "answer": "Yes.",
        "evidence": "All BERT experiments were trained for 500K steps. The code was written in Python and we used the Tensorflow libraries to create the models. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. The data was first processed into Tensorflow records as the input to the model. The set of hyperparameters which we found optimal after experimenting with different sets are in (Table TABREF10).\nThis set of parameters were chosen as there training performances were better than smaller models on modelling the long sequences of sub-words. We use the Adam optimizer BIBREF16 same as the English BERT. A maximum sequence length of 300 encompasses 98 percent of the training data and also allows us to fit larger models on the GPU card. Hyper-parameter optimization is very difficult in case of these models as they take around 15 days to train given the resources. The hyperparameter choices were therefore more dependant on the original BERT with little tweaks. We assess the training performance of the the model in the (Table TABREF11).\nWhen we train the BERT model we mask some percentage of the input tokens at random, and then predict those masked tokens, this is known as Masked LM. The masked LM loss, refers specifically to the loss when the masked language model predicts on the masked tokens. The masked LM accuracy refers specifically to the accuracy with which the model predicts on the masked tokens. The loss for both the models are far off from the Masked LM loss of the English BERT, key difference being the pre-training data for both the language models are quite different. Google training their model on 3.3 Billion words from BooksCorpus BIBREF17 and the English Wikipedia and our model being trained on 144 million words. Comparing the two Finnish models, the left-marked model has a better training performance than left+right-marked model.\nThe results of the pseudo-perplexity described in the previous section to evaluate the above models on the test data-set is in table (Table TABREF12).The test dataset is of a different context when compared to the training data, and interestingly both the models are quite confident when it comes to the test dataset. The pseudo-perplexity values of left-marked are lower when compared to left-right-marked signifying that it is more confident.\nWe cannot directly compare the perplexity scores BERT model with a unidirectional LSTM model as both are calculated in a different manner. We can experiment to compare it with a Bi-directional LSTM or use a downstreaming task to compare both the performances. We could also randomly mask tokens and then compare the prediction accuracy on the masked tokens.\nAll Transformer-XL experiments are also trained equally for 500K steps. The code was written in Python and we used the PyTorch libraries for model creation. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. Two sets of hyperparameters were chosen to be compared after some initial optimization and are in (Table TABREF14)\nFrom the above parameter choice, we wanted to experiment, whether providing more Segment and Memory length is advantageous (longer context) than a larger model. These parameters where chosen after some hyperparameter optimization. Same as for BERT we use the Adam optimizer, but we also use a cosine annealing learning rate scheduler to speed-up training BIBREF18. The training performance results are in (Table TABREF15)\nAs opposed to BERT, the left+right-marked models have a better training performance than their counterpart. Interestingly the larger model trains much better when compared to providing larger contexts. The same set of parameters for the 32-32 model cannot be replicated for 150-150 model as the latter takes a lot of space on the GPU card. The test set is same as that used with BERT and the results are in (Table TABREF16). The test performance is similar to that of the training performance with left-right-marked large model(32-32) performing the best. We can directly compare the perplexity scores with the previous best BIBREF19 as both are unidirectional models, Transformer-XL model has outperformed the latter by 27%.\nTransformer-XL and BERT both have low perplexity and pseudo-perplexity scores, but both cannot be directly compared as they are calculated quite differently (Eq.DISPLAY_FORM4, Eq.DISPLAY_FORM6). The dramatically low scores of BERT indicate that per word predicted probability is higher than that of a uni-directional model. Thus the predicted word probability distribution is much sharper when compared to the XL model probability distribution. At this point, we cannot say which model architecture has performed better- BERT or Transformer-XL, despite both of them achieving good low perplexity scores. We would need to experiment with a downstreaming task in-order to fairly compare model performances.\nTransformer-XL and BERT both have low perplexity and pseudo-perplexity scores, but both cannot be directly compared as they are calculated quite differently (Eq.1, Eq.3).",

Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other.

        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nIn this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations (Kim, 2014), and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.",

        "answer": "They propose concept-mapbased MDS which is a totally novel task and create a new dataset and a new crowdsourcing scheme for it, they also provide an evaluation protocol and baseline.",
        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ).

QE research has grown increasingly popular due to the improved quality of MT systems, and potential for reductions in post-editing time and the corresponding savings in labor costs BIBREF2 , BIBREF3 . QE can be performed on multiple granularities, including at word level, sentence level, or document level. In this paper, we focus on quality estimation at word level, which is framed as the task of performing binary classification of translated tokens, assigning “OK” or “BAD” labels.\nEarly work on this problem mainly focused on hand-crafted features with simple regression/classification models BIBREF4 , BIBREF5 . Recent papers have demonstrated that utilizing recurrent neural networks (RNN) can result in large gains in QE performance BIBREF6 . However, these approaches encode the context of the target word by merely concatenating its left and right context words, giving them limited ability to control the interaction between the local context and the target word.\nIn this paper, we propose a neural architecture, Context Encoding Quality Estimation (CEQE), for better encoding of context in word-level QE. Specifically, we leverage the power of both (1) convolution modules that automatically learn local patterns of surrounding words, and (2) hand-crafted features that allow the model to make more robust predictions in the face of a paucity of labeled data. Moreover, we further utilize stacked recurrent neural networks to capture the long-term dependencies and global context information from the whole sentence.\nWe tested our model on the official benchmark of the WMT18 word-level QE task. On this task, it achieved highly competitive results, with the best performance over other competitors on English-Czech, English-Latvian (NMT) and English-Latvian (SMT) word-level QE task, and ranking second place on English-German (NMT) and German-English word-level QE task.\nWe tested our model on the official benchmark of the WMT18 word-level QE task.",

        "evidence": "Rhetorical Structure Theory (RST) BIBREF0 is a technique of Natural Language Processing (NLP), in which a document can be structured hierarchically according to its discourse. The generated hierarchy, a tree, provides information associated with the boundaries of the discourse segments and related to their importance and dependencies. The figure FIGREF1 shows an example of such a rethorical tree. In the rethorical parsing process, the text has been divided into five units. In the figure FIGREF1, the arrow that leaves the unit (2) towards the unit (1) symbolizes that the unit (2) is the satellite of the unit (1), which is the core in a “Concession” relationship. In turn, the units (1) and (2) comprise the nucleus of three “Demonstration” relationships.\nThe discursive analysis of a document normally includes three consecutive steps: 1) discursive segmentation; 2) detection of the discursive relations; 3) construction of the hierarchical rhetorical tree. Regarding the discursive segmentation, there are segmenters in several languages. However, each piece depends on sofisticated linguistic resources, which complicates the reproduction of the experiments in other languages. Consequently, the development of multilingual systems using discursive analysis are yet to be developed. Diverse applications based on the latest technologies require at least one of the three steps mentioned above BIBREF1, BIBREF2, BIBREF3. In this context, the idea of exploring the architecture of a generic system that is able not only of segmenting a text correctly but also of adapting it to any language, was a great motivation of this research work.\nIn this article we show the preliminary results of a generic segmenter composed of several systems (different segmentation strategies). In addition, we describe an automatic evaluation protocol of discursive segmentation. The article is composed by the following sections: state of the art (SECREF2), which presents a brief bibliographic review; Description of the Annodis (SECREF3) corpus used in our tests and of the general architecture of the proposed systems (SECREF4); Segmentation strategies (SECREF5), which characterizes the different methods implemented to segment the text; results of our numerical experiments (sec:experiments); and we conclude with our conclusions and perspectives (SECREF7).\nIn the figure 1, the arrow that leaves the unit (2) towards the unit (1) symbolizes that the unit (2) is the satellite of the unit (1), which is the core in a “Concession” relationship.

        "evidence": "Distributed representation of word sense provides us with the ability to perform several operations on the word. One of the most important operations on a word is to obtain the set of words whose meaning is similar to the word, or whose usage in text is similar to the word. We call this set the neighbor of the word. When a word has several senses, it is called a polysemic word. When a word has only one sense, it is called a monosemic word. We have observed that the neighbor of a polysemic word consists of words that resemble the primary sense of the polysemic word. We can explain this fact as follows. Even though a word may be a polysemic, it usually corresponds to a single vector in distributed representation. This vector is primarily determined by the major sense, which is most frequently used. The information about a word's minor sense is subtle, and the effect of a minor sense is difficult to distinguish from statistical fluctuation.\nTo measure the effect of a minor sense, this paper proposes to use the concept of surrounding uniformity. The surrounding uniformity roughly corresponds to statistical fluctuation in the vectors that correspond to the words in the neighbor. We have found that there is a difference in the surrounding uniformity between a monosemic word and a polysemic word. This paper describes how to compute surrounding uniformity for a given word, and discuss the relationship between surrounding uniformity and polysemy.\nWe choose the uniformity of vectors, which can be regarded as general case of triangle inequality. The uniformity of a set of vectors is a ratio, i.e., the size of the vector of the vector addition of the vectors divided by the scalar sum of the sizes of the vectors. If and only if all directions of the vectors are the same, the uniformity becomes 1.0. We compute this uniformity for the neighbors, including the word itself. Surrounding Uniformity (SU) can be expressed as follows: $SU(\\vec{w}) = \\frac{|\\vec{s}(\\vec{w})|}{|\\vec{w}| + \\sum _{i}^{N}|\\vec{a_i}(\\vec{w})|}$\nwhere $\\vec{s}(\\vec{w}) = \\vec{w} + \\sum _{i}^{N} \\vec{a_i}(\\vec{w}).$\nOne of the most important operations on a word is to obtain the set of words whose meaning is similar to the word, or whose usage in text is similar to the word.

        "question": "How do we increase voter turnout in the United States?",
        "evidence": "",
        "answer": "Voter turnout in the United States varies from state to state and, as a whole, is comparatively low with respect to other democracies. There are institutional as well as psychological factors that affect turnout. Institutional factors include voter registration requirements, timing and frequency of elections, location of polling places, and complexity of ballots. Psychological factors include political efficacy, interest and engagement of the electorate, and political party membership. Voter turnout in the United States can be increased, and I will propose two simple reforms that would increase voter turnout. I will also propose another more complex reform that would dramatically increase voter turnout but would be difficult to implement by the state governments.\nSeveral institutional factors determine voter turnout. As each state has the power to hold elections, these factors vary across the states. The difficulty or ease of voter registration will have an impact on turnout. Minnesota has a very high turnout allowing same-day voter registration, while Texas has a low turnout and has a 30-day requirement. The day and time an election is also held matters. For example, the U.S. holds federal elections on a Tuesday in November during work hours which reduces voter turnout. The frequency of elections will have an influence on turnout. There are many elections per year in the U.S., and voters get fatigued and stop going to the polls. Voters are also less likely to vote if they don't have convenient polling places that are nearby and easy to access. Schools are the best and most accessible polling locations, but the U.S. holds elections on Tuesdays, which limits the availability of school space and parking. Lastly, complex ballots diminish enthusiasm and negatively impact U.S. voter turnout.\nAlong with institutional factors, there are psychological factors that control voter turnout. One of which is political efficacy which is defined in two ways. The first is internal efficacy which is how well you think you are able to understand politics. The second is external efficacy which is how well you feel the system responds to your input. Essentially, if you think you are smart enough and your vote \"matters,\" you have high efficacy and tend to go to the polls. The next psychological factor is interest, which is a measure of how much you care about politics. If you don't care, it's highly unlikely that you will vote. The last psychological factor is partisanship. Are you a member of a political party? If yes, then it's more likely you'll go vote to support your party. \nBy voting age population, turnout in the U.S. is around 53%. This shows the United States has a low turnout compared to other democracies and puts the U.S. 7th from the bottom when compared to 35 other democracies. Australia has the highest turnout, with just over 90%. The reason for Australia's high turnout is that voting is compulsory, with fines for people who don't vote. \"Voting in Australia is like a party,\" with election day described as a country-wide BBQ with easy-to-access polling locations held on a Saturday. In Australia, \"Forcing people to engage in the process increases their knowledge of the issues and candidates,\" thereby increasing Australia's political interest and engagement. By contrast, polls in the U.S. consistently show us that Americans don't know much about politics and are neither engaged nor interested in politics. Converse argues that people in the U.S. have low levels of ideological constraint and conceptualization. This shows that Americans have low political efficacy.\n\tIn general American turnout is low, but Voter Eligible Population (VEP) turnout varies dramatically across the states. Hawaii has the least VEP turnout, with approximately 43%. To compare, the state with the highest VEP turnout is Minnesota, with 75%. Texas comes in 3rd from the bottom with 53%. Minnesota's high turnout is explained by \"easy access to the ballot,\" \"a sense of civic responsibility,\" \"high rates of educational attainment and income,\" and \"competitive and interesting elections.\" By comparison, the main reasons Hawaii turnout is so low are that it's \"hard to register,\" voter disinterest and low efficacy, and it's a \"one-party state\". This combination of institutional and psychological factors, beneficial in Minnesota, and detrimental in Hawaii, has a significant impact on a state's turnout. \n\tI propose two simple solutions to increase voter turnout. The first would be to move elections to the weekend or require that companies give employees the day off to vote. Sunday is the most common election day in the world outside the United States. I believe this would be a beneficial institutional factor that would increase voter turnout because the majority of other countries have higher voter turnout than the United States. Unfortunately, the chances of this happening are slim as Congress has proposed bills to move elections to the weekend or have a Federal holiday for voting, but these bills have never moved out of committees.\n\tThe second simple solution would address the institutional factor of registration requirements by implementing same-day voter registration in all 50 states. Minnesota allows for same-day registration, and its turnout is around 20% higher than Texas, which does not allow it. States that have implemented same-day voter registration have seen an average of a 5% increase in voters (\"Same Day Voter\"). To prevent voter fraud, systems should be put in place to make sure the voter hasn't already voted and to check for valid identification showing the voter is a resident of the state or county. Another deterrent to committing voter fraud would be criminal penalties, including jail time and fines. Enacting legislation in each state to implement a system to handle would take time, but I think it's possible as currently, 21 states allow same-day voting registration (\"Same Day Voter\"). \n\tThe third solution I propose would address most of the institutional factors. This would be an online/app-based voting option. The vast majority of Americans these days have mobile phones with internet connections. Those that don't would still have all of the current voting options, such as polling locations and mail-in voting. Security and verification would combine blockchain (similar to Bitcoin identities), biometrics, and facial recognition artificial intelligence. When registering to vote, a state agency would create your blockchain voter identification, fingerprint, and take a LiDAR(Light Detection and Ranging) 3D map of your face. These three technologies would ensure one vote per person. Also, this technology is all readily available and, while complex to implement, would provide several advantages over our current voting system. It would eliminate the need for convenient polling locations, as you can vote anywhere. The timing of elections would be fine, as you could vote during a work break. The frequency of elections would also be less of an issue because you wouldn't have to go to a polling location. The complexity of the ballot could be addressed in the application, which would allow links showing descriptions of candidates and issues.\n\tWhile voter turnout in the United States is low compared to other democratic countries, there are both simple and complex solutions that can increase voter participation. States with high voter turnout should be models for other states to follow as they have implemented practical reforms like same-day voter registration. The United States can then look to other countries and enact common sense solutions like voting on the weekend or on election holidays. Finally, we can use technology safely and responsibly to take voting into the 21st century and remove all the barriers to voting that our existing system places between the voter and the ballot.",

The semantic slot values (e.g. [restaurant_name], [time]) are more essential compared to other words in the summary. However, ROUGE did not take this into consideration. To address this drawback in ROUGE, we propose a new evaluation metric: Critical Information Completeness (CIC).

The town is also home to an assortment of other characters, including students, families, elementary school staff, and other various residents. Prominent settings include South Park Elementary, various neighborhoods and the surrounding mountain range, actual Colorado landmarks, and the businesses along the town's main street, all of which are based on the appearance of similar locations in Fairplay, Colorado. As one of the few television programs set in the Mountain West region that takes place outside the urban core of Denver, South Park frequently features the unique culture of the region, including cattle ranchers, Old West theme parks, snowy climates, mountaineering, Mormons, real-life Colorado locations such as Casa Bonita and Cave of the Winds, and many other regionally specific characteristics.\n\nStan is portrayed as the everyman of the group, described in official media as an \"average, American 4th grader.\" Kyle is Jewish, and his portrayal as one of the few such people in South Park is often dealt with satirically. Stan is modeled after Parker, while Kyle is modeled after Stone. They are best friends, and their friendship, symbolically intended to reflect Parker and Stone's friendship, is a common topic throughout the series. Cartman (as he is commonly referred to) is amoral and increasingly psychopathic, and is commonly portrayed as an antagonist. His staunch antisemitism has resulted in a progressive rivalry with Kyle. Kenny, who comes from a poor family, tightly wears his parka hood to the point where it obscures most of his face and muffles his speech. During the first five seasons, Kenny died in almost every episode before reappearing in the next with no definite explanation. He was killed off in the fifth season episode \"Kenny Dies\", being reintroduced in the sixth season finale. Since then, Kenny is depicted as dying sporadically.

The distance is measured by a function called a metric or distance function. Metric spaces are the most general setting for studying many of the concepts of mathematical analysis and geometry.\n\nThe most familiar example of a metric space is 3-dimensional Euclidean space with its usual notion of distance. Other well-known examples are a sphere equipped with the angular distance and the hyperbolic plane. A metric may correspond to a metaphorical, rather than physical, notion of distance: for example, the set of 100-character Unicode strings can be equipped with the Hamming distance, which measures the number of characters that need to be changed to get from one string to another.\n\nSince they are very general, metric spaces are a tool used in many different branches of mathematics. Many types of mathematical objects have a natural notion of distance and therefore admit the structure of a metric space, including Riemannian manifolds, normed vector spaces, and graphs. In abstract algebra, the p-adic numbers arise as elements of the completion of a metric structure on the rational numbers. Metric spaces are also studied in their own right in metric geometry and analysis on metric spaces.\n\nMany of the basic notions of mathematical analysis, including balls, completeness, as well as uniform, Lipschitz, and Hölder continuity, can be defined in the setting of metric spaces.

        "evidence": "It is often the case that the meaning of a word is determined by its context, such as the previous word and the following word. [id=lq]Also, negations and emotion transitions are context sensitive. However, the memory network described in Section SECREF3 has only one memory slot with size INLINEFORM0 to represent a clause, where INLINEFORM1 is the dimension of a word embedding and INLINEFORM2 is the length of a clause. It means that when the memory network models a clause, it only considers each word separately.\nIn order to capture [id=lq]context information for clauses, we propose a new architecture which contains more memory slot to model the context with a convolutional operation. The basic architecture of Convolutional Multiple-Slot Memory Network (in short: ConvMS-Memnet) is shown in Figure 4.\nConsidering the text length is usually short in the dataset used here for emotion cause extraction, we set the size of the convolutional kernel to 3. That is, the weight of word INLINEFORM0 [id=lq]in the INLINEFORM1 -th position considers both the previous word INLINEFORM2 and the following word INLINEFORM3 by a convolutional operation: DISPLAYFORM0 \nFor the first and the last word in a clause, we use zero padding, INLINEFORM0 , where INLINEFORM1 is the length of a clause. Then, the attention [id=lq]weightsignal for each word position in the clause is [id=lq]now defined as: DISPLAYFORM0 \nNote that we obtain the attention for each position rather than each word. It means that the corresponding attention for the INLINEFORM0 -th word in the previous convolutional slot should be INLINEFORM1 . Hence, there are three prediction output vectors, namely, INLINEFORM2 , INLINEFORM3 , INLINEFORM4 : DISPLAYFORM0 \nAt last, we concatenate the three vectors as INLINEFORM0 for the prediction by a softmax function: DISPLAYFORM0 \nHere, the size of INLINEFORM0 is INLINEFORM1 . Since the prediction vector is a concatenation of three outputs. We implement a concatenation operation rather than averaging or other operations because the parameters in different memory slots can be updated [id=lq]respectively in this way by back propagation. The concatenation of three output vectors forms a sequence-level feature which can be used in the training. Such a feature is important especially [id=lq]when the size of annotated training data is small.\nFor deep architecture with multiple layer[id=lq]s training, the network is more [id=lq]complex (shown in Figure 5).\nFor the first layer, the query is an embedding of the emotion word, INLINEFORM0 .\nIn the next layer, there are three input queries since the previous layer has three outputs: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 . So, for the INLINEFORM3 -th layer ( INLINEFORM4 ), we need to re-define the weight function (5) as:\nIn the last layer, [id=lq]the concatenation of the three prediction vectors form the final prediction vector to generate the answer.\nFor model training, we use stochastic gradient descent and back propagation to optimize the loss function.

        "evidence": "The first step of PIF is to construct substitutes for the per-person latent variables ρ i and per-item latent variables τ k by fitting latent variable models to the social network and yesterday's purchases. The idea is that the per-person variables ρ i and z i drive each observed connection a ij in the social network. If we fit a latent variable model to the observed social network that has this same structure, the inferred latent variables will contain some of the same information contained by the confounder ρ i . The same idea applies to the observed data of purchases from yesterday and the confounder τ k . To implement this strategy, we fit models of networks and matrix factorization methods.\nThe idea behind substitutes was developed in Wang and Blei (2019a), in the deconfounder algorithm for multivariate treatments. Here, we extend these ideas to the social influence setting, where the social network and yesterday's purchases (\"treatments\" in our setting) are both needed to capture the information in the confounders.\nWe illustrate the technical ideas behind substitutes by defining them for the per-person variable ρ i . We fit a latent variable model to the observed network a. Standard generative models for networks model the likelihood of observing a connection between person i and person j using Kdimensional latent variables c i and c j on nodes, often called community membership. For concreteness, we will focus on a generative model with a Poisson likelihood, which has been well-studied for modeling social networks . The model assumes that each connection in the network is conditionally independent given the latent variables,\nWe perform inference in this model over the latent variables c 1:n . Each inferred variable ĉi is a substitute for some of the per-person confounders ρ i . We call the variables ĉ1:n per-person substitutes.\nFigure: (Left) The per-person confounder ρ i can be separated into traits u i that affect more than one connection in a i and in traits v i that affect a single connection in a i . (Right) The latent variable model posits the same conditional independence structure over a i as the causal model on the left.\nWhy are substitutes valid? Figure illustrates the justification behind per-person substitutes. Consider the connections a i made by person i, and for ease of explanation, suppose that there are no traits z i , which only affect the connections a i . Then, Figure shows that the perperson confounder ρ i can be separated into the traits u i (outlined in green) that affect more than one connection in the set a i and traits v i (outlined in red), which affect only one connection. The assumed causal model on the left in Figure implies that each connection a ij ∈ a i is conditionally independent given the per-person variable u i . That is,\nConsider the generative model on the right in Figure. We see that it posits the same conditional independence of observed variables a i given the latent variables c i . Assume that the generative model well-approximates the empirical distribution of the network, captured by each row a i of the adjacency matrix. Then, the per-person variables c i that render each observation a ij conditionally independent of the others must coincide with the variables u i posited in the causal model in Figure.\nWe make this idea concrete with a formal result and proof in the appendix.\nWhen does this not work? The per-person substitute ĉi cannot capture the confounder v i , which only affects one of the connection a i . This fact is because a per-person substitute ĉi can still render the observed connections a i conditionally independent without capturing the trait that affects a single connection. Put differently, such traits leave no observable implications in the data.\nWhat information is captured? The per-person substitute ĉi contains information about both variables ρ i and z i , since both drive the connections a i and render them conditionally independent (Figure). However, only the per-person variables ρ i are confounders. To target ρ-specific information, we can instead fit a joint factor model,\nwhich uses the community membership c to jointly model the network and yesterday's purchases.\nWe can construct per-person substitutes with inferred variables ĉi as before. We will compare both methods for constructing per-person substitutes in the empirical studies.\nWe will use the same ideas to find substitutes for the per-person confounders τ k that capture the attributes of an item k that cause people to purchase it (or not). As we noted, finding substitutes relies on models that posit the conditional independence of observed data given latent variables (e.g., Eq. ()). For heterogeneous data such as people's purchases of multiple products, one such a model is Poisson matrix factorization . Thus, to construct substitutes for some of the latent confounders τ k , we fit Poisson matrix factorization to yesterday's purchases,\nwhere Q is the number of factors. After performing inference over the latent variables d 1:n and w 1:m , each inferred variable ŵk is a substitute for the subset of per-item variables τ k that affect more than one purchase in x k = {x 1k , . . . , x nk }. We call each variable ŵk a per-item substitute.\nIn this section, we will formally state a result about valid substitutes for per-person and per-item confounders.\nProposition 7.1 Let u j ⊂ {ρ j , z j } be the traits of person j that affect more than one connection in a j . Suppose there exists a variable c j so that the distribution p(a j | c j ) factorizes as,\nfor parameters η a j . Then, the variable c j contains the information that is contained in the set of user traits u j . Let τ k be the attributes of item k that affect more than one purchase in x k . Suppose there exists a variable w k so that the distribution p(x k | w k ) factorizes as,\nfor parameters η x k . Then, the variable w k contains the information contained in the variable τ k .\nProof Assume that a variable w k which satisfies the factorization above exists. Then, by definition, each pair of variables (x ik , x i ′ k ) in the set x k are d-separated by w k . Suppose that w k does not contain all the information contained in the confounders τ k , common causes of multiple variables in x k . That means, there exists some subset U ⊂ τ k that is not contained in w k but which are parents of at least two variables, (x ak , x bk ) in x k . But, we assumed that w k d-seperates all pairs of variables in x k . By contradiction, w k contains all the information contained in τ k . The same proof applies for the variable c j .\nPoisson influence factorization (PIF) estimates social influence from observed social network data and and data from a behavior of interest, such as users purchasing items. PIF uses latent variable models of such data to construct substitutes for unobserved confounders: per-person variables that affect both connections and purchases, and per-item variables that drive purchases. PIF then uses substitutes as drop-in replacements when estimating social influence. We demonstrated the accuracy of PIF for estimating social influence on semi-synthetic datasets. In Section 7.6, we analyzed the sensitivity of PIF to assumption violations. Finally, we applied PIF to study real data from Last.fm.\nFuture work. In this paper, we made the assumption that influence only spreads behavior in a network from one time period to the next. One avenue of future work is modeling time-series influence. We also focused on Poisson factor models and generalized linear model of outcomes. Another avenue of future work is developing more flexible models of outcomes, networks and purchases. For example, it is worthwhile to study heterogeneous influence effects with outcome models that capture this variation. Finally, we only studied the estimation error of PIF empirically. It is important future work to establish technical results about estimation with finite samples and potentially mis-measured substitutes.\nThe first step of PIF is to construct substitutes for the per-person latent variables ρi and per-item latent variables τk by fitting latent variable models to the social network and yesterday’s purchases. The idea is that the per-person variables ρi and zi drive each observed connection aij in the social network. If we fit a latent variable model to the observed social network that has this same structure, the inferred latent variables will contain some of the same information contained by the confounder ρi . The same idea applies to the observed data of purchases from yesterday and the confounder τk. To implement this strategy, we fit models of networks (Holland et al., 1983; De Bacco et al., 2017; Ball et al., 2011; Contisciani et al., 2020; Peixoto, 2019; Gopalan and Blei, 2013; Hoff, 2008) and matrix factorization methods (Lee and Seung, 2001; Gopalan et al., 2013, 2015).

        "evidence": "Although internet users accept unilateral contracts such as terms of service on a regular basis, it is well known that these users rarely read them. Nonetheless, these are binding contractual agreements. A recent study suggests that up to 98% of users do not fully read the terms of service before accepting them BIBREF0 . Additionally, they find that two of the top three factors users reported for not reading these documents were that they are perceived as too long (`information overload') and too complicated (`difficult to understand'). This can be seen in Table TABREF3 , where a section of the terms of service for a popular phone app includes a 78-word paragraph that can be distilled down to a 19-word summary.\nThe European Union's BIBREF1 , the United States' BIBREF2 , and New York State's BIBREF3 show that many levels of government have recognized the need to make legal information more accessible to non-legal communities. Additionally, due to recent social movements demanding accessible and transparent policies on the use of personal data on the internet BIBREF4 , multiple online communities have formed that are dedicated to manually annotating various unilateral contracts.\nWe propose the task of the automatic summarization of legal documents in plain English for a non-legal audience. We hope that such a technological advancement would enable a greater number of people to enter into everyday contracts with a better understanding of what they are agreeing to. Automatic summarization is often used to reduce information overload, especially in the news domain BIBREF5 . Summarization has been largely missing in the legal genre, with notable exceptions of judicial judgments BIBREF6 , BIBREF7 and case reports BIBREF8 , as well as information extraction on patents BIBREF9 , BIBREF10 . While some companies have conducted proprietary research in the summarization of contracts, this information sits behind a large pay-wall and is geared toward law professionals rather than the general public.\nIn an attempt to motivate advancement in this area, we have collected 446 sets of contract sections and corresponding reference summaries which can be used as a test set for such a task. We have compiled these sets from two websites dedicated to explaining complicated legal documents in plain English.\nRather than attempt to summarize an entire document, these sources summarize each document at the section level. In this way, the reader can reference the more detailed text if need be. The summaries in this dataset are reviewed for quality by the first author, who has 3 years of professional contract drafting experience.\nThe dataset we propose contains 446 sets of parallel text. We show the level of abstraction through the number of novel words in the reference summaries, which is significantly higher than the abstractive single-document summaries created for the shared tasks of the Document Understanding Conference (DUC) in 2002 BIBREF11 , a standard dataset used for single document news summarization. Additionally, we utilize several common readability metrics to show that there is an average of a 6 year reading level difference between the original documents and the reference summaries in our legal dataset.\nIn initial experimentation using this dataset, we employ popular unsupervised extractive summarization models such as TextRank BIBREF12 and Greedy KL BIBREF13 , as well as lead baselines. We show that such methods do not perform well on this dataset when compared to the same methods on DUC 2002. These results highlight the fact that this is a very challenging task. As there is not currently a dataset in this domain large enough for supervised methods, we suggest the use of methods developed for simplification and/or style transfer.\nIn this paper, we begin by discussing how this task relates to the current state of text summarization and similar tasks in Section SECREF2 . We then introduce the novel dataset and provide details on the level of abstraction, compression, and readability in Section SECREF3 . Next, we provide results and analysis on the performance of extractive summarization baselines on our data in Section SECREF5 . Finally, we discuss the potential for unsupervised systems in this genre in Section SECREF6 .\nWe hope that such a technological advancement would enable a greater number of people to enter into everyday contracts with a better understanding of what they are agreeing to.",

        "evidence": "Problem. We apply HARI to modeling a human-assisted navigation (HAN) problem. In HAN, a human requests an agent to find an object in an indoor environment. Each task request asks the agent to go to a room of type r and find an object of type o (e.g., find a mug in a kitchen). The agent is equipped with a camera and shares its camera view with the human. We assume that the human is sufficiently familiar with the environment that they can recognize the agent's location by looking at its current view. Before issuing a task request, the human imagines a goal location (but do not reveal it to the agent). We are primarily interested in evaluating success in goal-finding, i.e. whether the agent can arrive at the human's intended goal location. Even though there could be multiple locations that match a request, the agent only succeeds if it arrives exactly at the chosen goal location. We also determine success in request-fulfilling, where the agent successfully fulfills a request if it navigates to any node that is within two meters of an object that matches the request.\nWhile an agent is performing a task, it may request the human to provide additional information via telecommunication (e.g., a chat app). Specifically, it can ask for a description of its current location (CUR), the goal location (GOAL), or a subgoal location that is on the path from its current location to the goal location (SUB). Detail about how the subgoals are determined is in the Appendix.\nOperation Environment. We construct the operation environments using the environment graphs provided by the Matterport3D simulator. Each environment graph is generated from a 3D model of a house where each node is a location in the house and each edge connects two nearby unobstructed locations. Each operation state s corresponds to a node in the graph. At any time, the agent's operation action space A consists of traversing to any of the nodes that are adjacent to its current node.\nWe employ a discrete bag-of-features representation for state descriptions. 3 A bag of features represents the information that the agent extracts from the raw input that the agent perceives (e.g., an image, a language sentence). Working with this intermediate input allows us to easily vary the type and amount of information given to the agent. Specifically, we simulate two settings of descriptions: dense and sparse. At evaluation time, the agent perceives sparse descriptions and request the assistant for dense descriptions. A dense description of a current location contains the room name at the location, and the features of M objects restricted to be within δ meters of the location. The features of each object consists of (i) its name, (ii) horizontal and vertical angles (relative to the current viewpoint), and (iii) distance (in meters) from the object to the current location. A dense description of a goal follows the same representation scheme. In the sparse setting, the current-location description does not include the room name. Moreover, we remove the features of objects that are not in the top 100 most frequent objects, emulating an imperfect object detector module. The sparse goal description (the task request) has only features of the target object and the room name where the object is located at. Especially, if a subgoal location is adjacent or coincides with the agent's current location, instead of describing room and object features, the human specifies the ground-truth action to go to the subgoal (an action is specified by its horizontal and vertical angles, and travel distance). 4   Experimental Procedure. We conduct our experiments in three phases. In the pre-training phase, we learn an operation policy π with dense descriptions of the current location and the goal. In the training phase, the agent perceives a sparse description of its current location and is given a sparse initial goal description. We use advantage actor-critic to learn an interaction policy ψ θ that controls how the agent communicates with the human and navigates in an environment. The human always returns dense descriptions. The interaction policy is trained in environments that are previously seen as well as unseen during pre-training. Finally, in the evaluation phase, the interaction policy is tested on three conditions: seen environment and target object type but starting from a new room (UNSEENSTR), seen environment but new target object type (UNSEENOBJ), and new environment (UNSEENENV).\nProblem.

        "evidence": "Back to 42 BC, the philosopher Cicero has raised the issue that although there were many Oratory classes, there were none for Conversational skills BIBREF0 . He highlighted how important they were not only for politics, but also for educational purpose. Among other conversational norms, he claimed that people should be able to know when to talk in a conversation, what to talk depending on the subject of the conversation, and that they should not talk about themselves.\nNorms such as these may become social conventions and are not learnt at home or at school. Social conventions are dynamic and may change according to context, culture and language. In online communication, new commonsense practices are evolved faster and accepted as a norm BIBREF1 , BIBREF2 . There is not a discipline for that on elementary or high schools and there are few linguistics researchers doing research on this field.\nOn the other hand, within the Artificial Intelligence area, some Conversational Systems have been created in the past decades since the test proposed by Alan Turing in 1950. The test consists of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from that of a human BIBREF3 . Turing proposed that a human evaluator would judge natural language conversations between a human and a machine that is designed to generate human-like responses. Since then, many systems have been created to pass the Turing's test. Some of them have won prizes, some not BIBREF4 . Although in this paper we do not focus on creating a solution that is able to build conversational systems that pass the Turing's test, we focus on NDS. From BIBREF5 , \"NDS are systems that try to improve usability and user satisfaction by imitating human behavior\". We refer to Conversational Systems as NDS, where the dialogues are expressed as natural language texts, either from artificial intelligent agents (a.k.a. bots) or from humans.\nThat said, the current popular name to systems that have the ability to make a conversation with humans using natural language is Chatbot. Chatbots are typically used in conversational systems for various practical purposes, including customer service or information acquisition. Chatbots are becoming more widely used by social media software vendors. For example, Facebook recently announced that it would make Facebook Messenger (its 900-million-user messaging app by 2016), into a full-fledged platform that allows businesses to communicate with users via chatbots. Google is also building a new mobile-messaging service that uses artificial intelligence know-how and chatbot technology. In addition, according to the Wall Street Journal, there are more than 2 billion users of mobile apps. Still, people can be reluctant to install apps. So it is believed that social messaging can be a platform and chatbots may provide a new conversational interface for interacting with online services, as chatbots are easier to build and deploy than apps BIBREF6 .\nChina seems to be the place where chatbots adoption and use is most advanced today. For example, China's popular WeChat messaging platform can take payments, scan QR codes, and integrate chatbot systems. WeChat integrates e-mail, chat, videocalls and sharing of large multimedia files. Users can book flights or hotels using a mixed, multimedia interaction with active bots. WeChat was first released in 2011 by Tecent, a Chinese online-gaming and social-media firm, and today more than 700 million people use it, being one of the most popular messaging apps in the world (The Economist 2016). WeChat has a mixture of real-live customer service agents and automated replies (Olson 2016).\nStill, current existing chatbot engines do not properly handle a group chat with many users and many chatbots. This makes the chatbots considerably less social, which is a problem since there is a strong demand of having social chatbots that are able to provide different kinds of services, from traveling packages to finance advisors. This happens because there is a lack of methods and tools to design and engineer the coordination and mediation among chatbots and humans, as we present in Sections 2 and 3. In this paper, we refer to conversational systems that are able to interact with one or more people or chatbots in a multi-party chat as MPCS. Altogether, this paper is not meant to advance the state of the art on the norms for MPCS. Instead, the main contributions of this paper are threefold:\nWe then present some discussion and future work in the last section.\n\"NDS are systems that try to improve usability and user satisfaction by imitating human behavior\".",

        "question": "How can Bernoulli's principle be derived from Newton's second law of motion?",
        "evidence": "Bernoulli's principle is a key concept in fluid dynamics that relates pressure, speed and height. Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.  The principle is named after the Swiss mathematician and physicist Daniel Bernoulli, who published it in his book Hydrodynamica in 1738.Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler in 1752 who derived Bernoulli's equation in its usual form. The principle is only applicable for isentropic flows: when the effects of irreversible processes (like turbulence) and non-adiabatic processes (e.g. thermal radiation) are small and can be neglected.\nBernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same at all points that are free of viscous forces. This requires that the sum of kinetic energy, potential energy and internal energy remains constant. Thus an increase in the speed of the fluid—implying an increase in its kinetic energy (dynamic pressure)—occurs with a simultaneous decrease in (the sum of) its potential energy (including the static pressure) and internal energy. If the fluid is flowing out of a reservoir, the sum of all forms of energy is the same because in a reservoir the energy per unit volume (the sum of pressure and gravitational potential ρ g h) is the same everywhere.\nBernoulli's principle can also be derived directly from Isaac Newton's second Law of Motion. If a small volume of fluid is flowing horizontally from a region of high pressure to a region of low pressure, then there is more pressure behind than in front. This gives a net force on the volume, accelerating it along the streamline.\nFluid particles are subject only to pressure and their own weight. If a fluid is flowing horizontally and along a section of a streamline, where the speed increases it can only be because the fluid on that section has moved from a region of higher pressure to a region of lower pressure; and if its speed decreases, it can only be because it has moved from a region of lower pressure to a region of higher pressure. Consequently, within a fluid flowing horizontally, the highest speed occurs where the pressure is lowest, and the lowest speed occurs where the pressure is highest.",

        "evidence": "A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. It will use this machine as a host to scan and infect other computers. When these new worm-invaded computers are controlled, the worm will continue to scan and infect other computers using these computers as hosts, and this behaviour will continue. Computer worms use recursive methods to copy themselves without host programs and distribute themselves based on exploiting the advantages of exponential growth, thus controlling and infecting more and more computers in a short time. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.\n\nMany worms are designed only to spread, and do not attempt to change the systems they pass through. However, as the Morris worm and Mydoom showed, even these \"payload-free\" worms can cause major disruption by increasing network traffic and other unintended effects.\n\nHistory\n\nThe actual term \"worm\" was first used in John Brunner's 1975 novel, The Shockwave Rider. In the novel, Nichlas Haflinger designs and sets off a data-gathering worm in an act of revenge against the powerful men who run a national electronic information web that induces mass conformity. \"You have the biggest-ever worm loose in the net, and it automatically sabotages any attempt to monitor it. There's never been a worm with that tough a head or that long a tail!\"\n\nThe second ever computer worm was devised to be an anti-virus software. Named Reaper, it was created by Ray Tomlinson to replicate itself across the ARPANET and delete the experimental Creeper program (the first computer worm, 1971).\n\nOn November 2, 1988, Robert Tappan Morris, a Cornell University computer science graduate student, unleashed what became known as the Morris worm, disrupting many computers then on the Internet, guessed at the time to be one tenth of all those connected. During the Morris appeal process, the U.S. Court of Appeals estimated the cost of removing the worm from each installation at between $200 and $53,000; this work prompted the formation of the CERT Coordination Center and Phage mailing list. Morris himself became the first person tried and convicted under the 1986 Computer Fraud and Abuse Act.",

        "answer": "Fundamentally, you either fit a Gaussian for class or have a very flexible nonparametric model. As we show in Appendix A.5 the embedding structure for ImageNet seems to be much more complicated than just Gaussians. The other point is that we do not require the retraining of base network as in DUQ. Finally, our method is sound from statistical point of view and we expect to coplement the study with statistical analysis in future works.",
        "evidence": "One of the things that caught our attention is superior performance of NUQ on ImageNet, given that it has very similar results with DDU on CIFAR-100. One of our hypotheses was that embeddings have more complex and multi-modal distribution for more complex Imagenet dataset compared to simpler CIFAR-100. To check this, we made t-SNE based embeddings of out-of-distribution and test data (see Figure 5). While we understand the limitation of this type of visualization, the ImageNet embeddings appear to be much more irregular compared to well-shaped clusters for CIFAR-100. Because of that the modelling of the class with single Gaussian (in DDU) might not work very well for ImageNet. NUQ approach performs the modelling of distributions in much more flexible way which is beneficial for approximation of complex distributions. We hypothesize that this is the reason of the NUQ’s superior performance.",

        "answer": "On text.",
        "evidence": "Spoken language understanding is a challenging and difficult task BIBREF3. All problems present in natural language understanding are significantly exacerbated by several factors related to the characteristics of spoken language.\nFirstly, each ASR engine introduces a mixture of systematic and stochastic errors which are intrinsic to the procedure of transcription of spoken audio. The quality of transcription, as measured by the popular word error rate (WER), attains the level of 5%-15% WER for high quality ASR systems for English BIBREF4, BIBREF5, BIBREF6, BIBREF7. The WER highly depends on the evaluation data difficulty and the speed to accuracy ratio. Importantly, errors in the transcription appear stochastically, both in audio segments which carry important semantic information, as well as in inessential parts of the conversation.\nAnother challenge stems from the fact that the structure of conversation changes dramatically when a human assumes an agency in the other party. When humans are aware that the other party is a machine (as is the case in dialogue chatbot interfaces), they tend to speak in short, well-structured turns following the subject-verb-object (SVO) sentence structure with a minimal use of relative clauses BIBREF8. This structure is virtually nonexistent in spontaneous speech, where speakers allow for a non-linear flow of conversation. This flow is further obscured by constant interruptions from backchannel or cross-talk utterances, repetitions, non-verbal signaling, phatic expressions, linguistic and non-linguistic fillers, restarts, and ungrammatical constructions.\nA substantial, yet often neglected difficulty, stems from the fact that most SLU tasks are applied to transcript segments representing a single turn in a typical scripted conversation. However, turn-taking in unscripted human-human conversations is far more haphazard and spontaneous than in scripted dialogues or human-bot conversations. As a result, a single logical turn may span multiple ASR segments and be interwoven with micro-turns of the other party or the contrary - be part of a larger segment containing many logical turns.\nASR transcripts lack punctuation, normalization, true-casing of words, and proper segmentation into phrases as these features are not present in the conversational input BIBREF9. These are difficult to correct as the majority of NLP algorithms have been trained and evaluated on text and not on the output of an ASR system. Thus, a simple application of vanilla NLP tools to ASR transcripts seldom produces actionable and useful results.\nFinally, speech based interfaces are defined by a set of dimensions, such as domain and vocabulary (retail, finance, entertainment), language (English, Spanish), application (voice search, personal assistant, information retrieval), and environment (mobile, car, home, distant speech recognition). These dimensions make it very challenging to provide a low cost domain adaptation.\nLast but not least, production ASR systems impose strict constraints on the additional computation that can be performed. Since we operate in a near real-time environment, this precludes the use of computationally expensive language models which could compensate for some of the ASR errors.\nASR transcripts lack punctuation, normalization, true-casing of words, and proper segmentation into phrases as these features are not present in the conversational input (Zelasko et al. ˙ , 2018). These are difficult to correct as the majority of NLP algorithms have been trained and evaluated on text and not on the output of an ASR system.

        "answer": "The Football Association Challenge Cup, more commonly known as the FA Cup, is an annual knockout football competition in men's domestic English football. First played during the 1871–72 season, it is the oldest national football competition in the world. It is organised by and named after The Football Association (The FA). Since 2015, it has been known as The Emirates FA Cup after its headline sponsor. A concurrent Women's FA Cup has been held since 1970.\n\nThe competition is open to all eligible clubs down to Level 9 of the English football league system with Level 10 clubs acting as stand-ins in the event of non-entries from above. Included in the competition are 20 professional clubs in the Premier League (level 1), 72 professional clubs in the English Football League (levels 2 to 4), and all clubs in steps 1–5 of the National League System (levels 5 to 9) as well as a tiny number of step 6 clubs acting as stand-ins for non-entries above. A record 763 clubs competed in 2011–12. The tournament consists of 12 randomly drawn rounds followed by the semi-finals and the final. Entrants are not seeded, although a system of byes based on league level ensures higher ranked teams enter in later rounds – the minimum number of games needed to win, depending on which round a team enters the competition, ranges from six to fourteen.\n\nThe first six rounds are the Qualifying Competition, from which 32 teams progress to the first round of the Competition Proper, meeting the first of the 48 professional teams from Leagues One and Two. The last entrants are the Premier League and Championship clubs, into the draw for the Third Round Proper. In the modern era, only one non-League team has ever reached the quarter-finals, and teams below Level 2 have never reached the final. As a result, significant focus is given to the smaller teams who progress furthest, especially if they achieve an unlikely \"giant-killing\" victory.\n\nWinners receive the FA Cup trophy, of which there have been two designs and five actual cups; the latest is a 2014 replica of the second design, introduced in 1911. Winners also qualify for the UEFA Europa League and a place in the upcoming FA Community Shield. Arsenal are the most successful club with fourteen titles and Arsène Wenger is the most successful manager in the history of the competition, having won seven finals as Arsenal's manager.\n\nLiverpool are the current holders, having beaten Chelsea 6–5 on penalties following a 0–0 draw in the 2022 final.",

        "answer": "A lower performance on the supervised language pairs.",
        "evidence": "Neural machine translation (NMT) exploits neural networks to directly learn to transform sentences from a source language to a target language BIBREF0 , BIBREF1 . Universal multilingual NMT discovered that a neural translation system can be trained on datasets containing source and target sentences in multiple languages BIBREF2 , BIBREF3 . Successfully trained models using this approach can be used to translate arbitrarily between any languages included in the training data. In low-resource scenarios, multilingual NMT has proven to be an extremely useful regularization method since each language direction benefits from the information of the others BIBREF4 , BIBREF5 .\nAn important research focus of multilingual NMT is zero-shot translation (ZS), or translation between languages included in multilingual data for which no directly parallel training data exists. Application-wise, ZS offers a faster and more direct path between languages compared to pivot translation, which requires translation to one or many intermediate languages. This can result in large latency and error propagation, common issues in non-end-to-end pipelines.From a representation learning point of view, there is evidence of NMT's ability to capture language-independent features, which have proved useful for cross-lingual transfer learning BIBREF6 , BIBREF7 and provide motivation for ZS translation. However it is still unclear if minimizing the difference in representations between languages is beneficial for zero-shot learning.\nOn the other hand, the current neural architecture and learning mechanisms of multilingual NMT is not geared towards having a common representation. Different languages are likely to convey the same semantic content with sentences of different lengths BIBREF8 , which makes the desiderata difficult to achieve. Moreover, the loss function of the neural translation model does not favour having sentences encoded in the same representation space regardless of the source language. As a result, if the network capacity is large enough, it may partition itself into different sub-spaces for different language pairs BIBREF9 .\nOur work here focuses on the zero-shot translation aspect of universal multilingual NMT. First, we attempt to investigate the relationship of encoder representation and ZS performance. By modifying the Transformer architecture of BIBREF10 to afford a fixed-size representation for the encoder output, we found that we can significantly improve zero-shot performance at the cost of a lower performance on the supervised language pairs. To the best of our knowledge, this is the first empirical evidence showing that the multilingual model can capture both language-independent and language-dependent features, and that the former can be prioritized during training.\nThis observation leads us to the most important contribution in this work, which is to propose several techniques to learn a joint semantic space for different languages in multilingual models without any architectural modification. The key idea is to prefer a source language-independent representation in the decoder using an additional loss function. As a result, the NMT architecture remains untouched and the technique is scalable to the number of languages in the training data. The success of this method is shown by significant gains on zero-shot translation quality in the standard IWSLT 2017 multilingual benchmark BIBREF11 . Finally, we introduce a more challenging scenario that involves more than one bridge language between source and target languages. This challenging setup confirms the consistency of our zero-shot techniques while clarifying the disadvantages of pivot-based translation.\nBy modifying the Transformer architecture of to afford a fixed-size representation for the encoder output, we found that we can significantly improve zero-shot performance at the cost of a lower performance on the supervised language pairs.",

        "question": "What categories are the reasoning methods of MRC systems in existing literature can be grouped into?",
        "answer": "1) single-step reasoning  2) multi-step reasoning with a fixed number of stepsand 3) dynamic multistep reasoning.",
        "evidence": "The recent progress in MRC is largely due to the introduction of large-scale datasets. CNN/Daily Mail BIBREF0 and SQuAD BIBREF1 are two popular and widely-used datasets. More recently, other datasets using different collection methodologies have been introduced, such as MS MARCO BIBREF11 , NewsQA BIBREF12 and RACE BIBREF7 . For example, MS MARCO collects data from search engine queries and user-clicked results, thus contains a broader topic coverage than Wikipedia and news articles in SQuAD and CNN/Daily Mail. Among the large number of MRC datasets, RACE focuses primarily on developing MRC models with near-human capability. Questions in RACE come from real English exams designed specifically to test human comprehension. This makes RACE an appealing testbed for DFN; we will further illustrate this in Section \" RACE - The MRC Task\" .\nThe word “fusion” for MRC was first used by FusionNet BIBREF4 to refer to the process of updating the representation of passage (or question) using information from the question (or passage) representation. A typical way of fusion is through attention: for example, BiDAF BIBREF2 uses a bi-directional attention, where the representation of passage (or question) vectors are re-weighted by their similarities to the question (or passage) vectors. We will use “fusion” and “attention” interchangeably throughout the paper.\nIn the attention process of state-of-the-art MRC models, a pre-defined attention strategy is often applied. BIBREF13 proposed a Bi-directional Multi-Perspective Matching (BiMPM) model, which uses attention with multiple perspectives characterized by different parameters. Although multi-perspective attention might be able to handle different types of questions, all perspectives are used for all the questions. DFN is inspired by BiMPM, but our dynamic attention process is more adaptive to variations of questions.\nAnother important component of MRC systems is the answer module, which performs reasoning to generate the final prediction. The reasoning methods in existing literature can be grouped into three categories: 1) single-step reasoning BIBREF14 , BIBREF15 , BIBREF2 , BIBREF16 ; 2) multi-step reasoning with a fixed number of steps BIBREF17 , BIBREF18 , BIBREF19 ; and 3) dynamic multi-step reasoning (ReasoNet BIBREF6 ). In particular, BIBREF19 proposed handling the variations in passages and questions using Maxout units and iterative reasoning. However, this model still applies static attention and reasoning (with fixed multiple steps), where the same attention strategy is applied to all questions. DFN can be seen as an extension of ReasoNet, in the sense that the dynamic strategy is applied not only in the reasoning process but also in the attention process.\nThe idea of dynamic attention has been applied to article recommendations BIBREF20 . For MRC, Andreas et al. (2016) proposed a dynamic decision process for reading comprehension task BIBREF8 . In their dynamic neural module networks, the MRC task is divided into several predefined steps (e.g., finding, lookup, relating), and a neural network is dynamically composed via RL based on parsing information. In DFN, we also incorporate dynamic decisions, but instead of using fixed steps, we apply dynamic decisions to various attention strategies and flexible reasoning steps.\nAnother important component of MRC systems is the answer module, which performs reasoning to generate the final prediction. The reasoning methods in existing literature can be grouped into three categories: 1) single-step reasoning (Chen et al., 2016, 2017; Seo et al., 2016; Wang et al., 2017a); 2) multi-step reasoning with a fixed number of steps (Dhingra et al., 2016; Sordoni et al., 2016; Xiong et al., 2016); and 3) dynamic multistep reasoning (ReasoNet (Shen et al., 2017)).",

        "question": "Based on the following passage what is the more dominant force in the universe?",
        "evidence": "The concept of the electric field was introduced by Michael Faraday. An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field. The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses, and like it, extends towards infinity and shows an inverse square relationship with distance. However, there is an important difference. Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion. Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero. Thus gravity is the dominant force at distance in the universe, despite being much weaker.\nAn electric field generally varies in space and its strength at any one point is defined as the force (per unit charge) that would be felt by a stationary, negligible charge if placed at that point. The conceptual charge, termed a 'test charge', must be vanishingly small to prevent its own electric field disturbing the main field and must also be stationary to prevent the effect of magnetic fields. As the electric field is defined in terms of force, and force is a vector, having both magnitude and direction, so it follows that an electric field is a vector field.\nThe study of electric fields created by stationary charges is called electrostatics. The field may be visualised by a set of imaginary lines whose direction at any point is the same as that of the field. This concept was introduced by Faraday, whose term 'lines of force' still sometimes sees use. The field lines are the paths that a point positive charge would seek to make as it was forced to move within the field; they are however an imaginary concept with no physical existence, and the field permeates all the intervening space between the lines. Field lines emanating from stationary charges have several key properties: first, that they originate at positive charges and terminate at negative charges; second, that they must enter any good conductor at right angles, and third, that they may never cross nor close in on themselves.",

This information can be exploited in decision making processes but, to be useful, it should be transformed and presented in ways that make its intrinsic knowledge more readily intelligible. For that, we need efficient methods and tools that quickly extract useful information from unstructured text collections. Such demand can be observed, for instance, in Biology, where researchers, in order to be abreast of all developments, need to analyse new biomedical literature on a daily basis BIBREF2 . Another application is on fraud and corruption studies where the network information — the set of actors and their relationships — is implicitly stored in unstructured natural-language documents BIBREF3 . Hence, text mining and information extraction are required to pre-process the texts in order to extract the entities and the relations between them.\nInformation extraction is a challenging task mainly due to the ambiguous features of natural-language. Moreover, most tools need to be adapted to different human languages and to different domains BIBREF4 . In fact, the language of the processed texts is still the decisive factor when choosing among existing information extraction technologies. This is also true for the task of entity extraction (Named Entity Recognition - NER).\nFor several reasons, text mining tools are typically first developed for English and only afterwards extended to other languages. Thus, there are still relatively few text mining tools for Portuguese and even less that are freely accessible. In particular, for the named entities recognition task in Portuguese texts, we find three extractors available: Alchemy, Zemanta and Rembrandt BIBREF5 . We also find some studies where the measures ( INLINEFORM0 , INLINEFORM1 and INLINEFORM2 ) for those extractors are computed and compared BIBREF6 , but their comparative effectiveness remains domain and final purpose dependent.\nIn this work, we present PAMPO (PAttern Matching and POs tagging based algorithm for NER), a new method to automatically extract named entities from unstructured texts, applicable to the Portuguese language but potentially adaptable to other languages as well.

        "evidence": "Rouge functions based on the assumption that in order for a summary to be of high quality, it has to share many words or phrases with a human gold summary. However, different terminology may be used to refer to the same concepts and thus relying only on lexical overlaps may underrate content quality scores. To overcome this problem, we propose an approach based on the premise that concepts take meanings from the context they are in, and that related concepts co-occur frequently.\nOur proposed metric is based on analysis of the content relevance between a system generated summary and the corresponding human written gold-standard summaries. On high level, we indirectly evaluate the content relevance between the candidate summary and the human summary using information retrieval. To accomplish this, we use the summaries as search queries and compare the overlaps of the retrieved results. Larger number of overlaps, suggest that the candidate summary has higher content quality with respect to the gold-standard. This method, enables us to also reward for terms that are not lexically equivalent but semantically related. Our method is based on the well established linguistic premise that semantically related words occur in similar contexts BIBREF5 . The context of the words can be considered as surrounding words, sentences in which they appear or the documents. For scientific summarization, we consider the context of the words as the scientific articles in which they appear. Thus, if two concepts appear in identical set of articles, they are semantically related. We consider the two summaries as similar if they refer to same set of articles even if the two summaries do not have high lexical overlaps. To capture if a summary relates to a article, we use information retrieval by considering the summaries as queries and the articles as documents and we rank the articles based on their relatedness to a given summary. For a given pair of system summary and the gold summary, similar rankings of the retrieved articles suggest that the summaries are semantically related, and thus the system summary is of higher quality.\nBased on the domain of interest, we first construct an index from a set of articles in the same domain. Since TAC 2014 was focused on summarization in the biomedical domain, our index also comprises of biomedical articles. Given a candidate summary INLINEFORM0 and a set of gold summaries INLINEFORM1 ( INLINEFORM2 ; INLINEFORM3 is the total number of human summaries), we submit the candidate summary and gold summaries to the search engine as queries and compare their ranked results. Let INLINEFORM4 be the entire index which comprises of INLINEFORM5 total documents.\nLet INLINEFORM0 be the ranked list of retrieved documents for candidate summary INLINEFORM1 , and INLINEFORM2 the ranked list of results for the gold summary INLINEFORM3 . These lists of results are based on a rank cut-off point INLINEFORM4 that is a parameter of the system. We provide evaluation results on different choices of cut-off point INLINEFORM5 in the Section SECREF5 We consider the following two scores: (i) simple intersection and (ii) discounted intersection by rankings. The simple intersection just considers the overlaps of the results in the two ranked lists and ignores the rankings. The discounted ranked scores, on the other hand, penalizes ranking differences between the two result sets. As an example consider the following list of retrieved documents (denoted by INLINEFORM6 s) for a candidate and a gold summary as queries:\nResults for candidate summary: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 \nResults for gold summary: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 \nThese two sets of results consist of identical documents but the ranking of the retrieved documents differ. Therefore, the simple intersection method assigns a score of 1.0 while in the discounted ranked score, the score will be less than 1.0 (due to ranking differences between the result lists).\nWe now define the metrics more precisely. Using the above notations, without loss of generality, we assume that INLINEFORM0 . Sera is defined as follows: INLINEFORM1 \nTo also account for the ranked position differences, we modify this score to discount rewards based on rank differences. That is, in ideal score, we want search results from candidate summary ( INLINEFORM0 ) to be the same as results for gold-standard summaries ( INLINEFORM1 ) and the rankings of the results also be the same. If the rankings differ, we discount the reward by log of the differences of the ranks. More specifically, the discounted score (Sera-Dis) is defined as: INLINEFORM2 \nwhere, as previously defined, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are total number of human gold summaries, result list for the candidate summary and result list for the human gold summary, respectively. In addition, INLINEFORM3 shows the INLINEFORM4 th results in the ranked list INLINEFORM5 and INLINEFORM6 is the maximum attainable score used as the normalizing factor.\nWe use elasticsearch[1], an open-source search engine, for indexing and querying the articles. For retrieval model, we use the Language Modeling retrieval model with Dirichlet smoothing BIBREF6 . Since TAC 2014 benchmark is on summarization of biomedical articles, the appropriate index would be the one constructed from articles in the same domain. Therefore, we use the open access subset of Pubmed[2] which consists of published articles in biomedical literature.\n[1]https://github.com/elastic/elasticsearch [2]PubMed is a comprehensive resource of articles and abstracts published in life sciences and biomedical literature http://www.ncbi.nlm.nih.gov/pmc/\nWe also experiment with different query (re)formulation approaches. Query reformulation is a method in Information Retrieval that aims to refine the query for better retrieval of results. Query reformulation methods often consist of removing ineffective terms and expressions from the query (query reduction) or adding terms to the query that help the retrieval (query expansion). Query reduction is specially important when queries are verbose. Since we use the summaries as queries, the queries are usually long and therefore we consider query reductions.\nIn our experiments, the query reformulation is done by 3 different ways: (i) Plain: The entire summary without stopwords and numeric values; (ii) Noun Phrases (NP): We only keep the noun phrases as informative concepts in the summary and eliminate all other terms; and (iii) Keywords (KW): We only keep the keywords and key phrases in the summary. For extracting the keywords and keyphrases (with length of up to 3 terms), we extract expressions whose idf[1] values is higher than a predefined threshold that is set as a parameter. We set this threshold to the average idf values of all terms except stopwords. idf values are calculated on the same index that is used for the retrieval.\n[1]Inverted Document Frequency\nWe hypothesize that using only informative concepts in the summary prevents query drift and leads to retrieval of more relevant documents. Noun phrases and keywords are two heuristics for identifying the informative concepts.\nIn our experiments, the query reformulation is done by 3 different ways: (i) Plain: The entire summary without stopwords and numeric values; (ii) Noun Phrases (NP): We only keep the noun phrases as informative concepts in the summary and eliminate all other terms; and (iii) Keyword (KW): We only keep the keywords and key phrases in the summary.",

        "evidence": "",
        "answer": "A progressive consumption tax would be a good substitute for a progressive income tax because it would produce greater economic efficiencies by promoting investment and savings while eliminating the income tax's disincentivizing of work. Unlike a sales tax imposed at the point of sale, a consumption tax could be structured to be progressive rather than regressive, by using a year end tax return to calculate 'net consumption' during a given tax year, with the return summing all sales of qualified investments and then subtracting all purchases of new qualified investments. The tax return then apply a progressive tax rate to the total net investment. Much of the complexity of the current tax code would be eliminated. There would no longer be a need for complex calculations relating to capital gains, based on the concept of 'tax basis' and other arcane notions. Complexities relating to tax beneficial retirement-related savings accounts would also become unnecessary. Investors would no longer be penalized for efficiency-driven portfolio rebalancing. Billionaires would not be taxed significantly if they live frugally, but they could be taxed at very high rates for substantial consumption. A billionaire who buys large yachts, multiple mega-mansions, etc. would pay high taxes. A billionaire who lives modestly would not. But the latter billionaire is keeping her money invested in the economy, providing resources that will further economic growth. Opponents of a consumption tax cite the fact that most consumption taxes are thought to be regressive. However, as perviously mentioned, the consumption tax could be structured to be progressive, and in fact could be structured to be even more progressive than the current income tax. The progressive rates could be based on wealth rather than the amount of annual consumption or income. It would even be possible to tax consumption at over 100% in the case of billionaires. For example, if someone had a net worth of over $10 billion, we could tax that person's consumption at 150%. Regressiveness concerns can also be addressed by exempting a large portion of consumption. Annual consumption under a certain level, say $30,000 per year, could be tax free, or taxed at a low sales-tax-like rate of, say, 5%.

        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nOur method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents [2].",

Many Linux distributions use the word \"Linux\" in their name, but the Free Software Foundation uses the name \"GNU/Linux\" to emphasize the importance of GNU software, causing some controversy.",
        "answer": "After AT&T had dropped out of the Multics project, the Unix operating system was conceived and implemented by Ken Thompson and Dennis Ritchie (both of AT&T Bell Laboratories) in 1969 and first released in 1970. Later they rewrote it in a new programming language, C, to make it portable. The availability and portability of Unix caused it to be widely adopted, copied and modified by academic institutions and businesses.\n\nIn 1977, the Berkeley Software Distribution (BSD) was developed by the Computer Systems Research Group (CSRG) from UC Berkeley, based on the 6th edition of Unix from AT&T. Since BSD contained Unix code that AT&T owned, AT&T filed a lawsuit (USL v. BSDi) in the early 1990s against the University of California. This strongly limited the development and adoption of BSD.\n\nOnyx Systems began selling early microcomputer-based Unix workstations in 1980. Later, Sun Microsystems, founded as a spin-off of a student project at Stanford University, also began selling Unix-based desktop workstations in 1982. While Sun workstations didn't utilize commodity PC hardware like Linux was later developed for, it represented the first successful commercial attempt at distributing a primarily single-user microcomputer that ran a Unix operating system.\n\nIn 1983, Richard Stallman started the GNU project with the goal of creating a free UNIX-like operating system. As part of this work, he wrote the GNU General Public License (GPL). By the early 1990s, there was almost enough available software to create a full operating system. However, the GNU kernel, called Hurd, failed to attract enough development effort, leaving GNU incomplete.[citation needed]\n\nIn 1985, Intel released the 80386, the first x86 microprocessor with a 32-bit instruction set and a memory management unit with paging.\n\nIn 1986, Maurice J. Bach, of AT&T Bell Labs, published The Design of the UNIX Operating System. This definitive description principally covered the System V Release 2 kernel, with some new features from Release 3 and BSD.\n\nIn 1987, MINIX, a Unix-like system intended for academic use, was released by Andrew S. Tanenbaum to exemplify the principles conveyed in his textbook, Operating Systems: Design and Implementation. While source code for the system was available, modification and redistribution were restricted. In addition, MINIX's 16-bit design was not well adapted to the 32-bit features of the increasingly cheap and popular Intel 386 architecture for personal computers. In the early nineties a commercial UNIX operating system for Intel 386 PCs was too expensive for private users.\n\nThese factors and the lack of a widely adopted, free kernel provided the impetus for Torvalds' starting his project. He has stated that if either the GNU Hurd or 386BSD kernels had been available at the time, he likely would not have written his own.",

        "answer": "Twitter data crawled in a time period",
        "evidence": "Sarcasm is defined as “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”. As the fields of affective computing and sentiment analysis have gained increasing popularity BIBREF0 , it is a major concern to detect sarcastic, ironic, and metaphoric expressions. Sarcasm, especially, is key for sentiment analysis as it can completely flip the polarity of opinions. Understanding the ground truth, or the facts about a given event, allows for the detection of contradiction between the objective polarity of the event (usually negative) and its sarcastic characteristic by the author (usually positive), as in “I love the pain of breakup”. Obtaining such knowledge is, however, very difficult.\nIn our experiments, we exposed the classifier to such knowledge extracted indirectly from Twitter. Namely, we used Twitter data crawled in a time period, which likely contain both the sarcastic and non-sarcastic accounts of an event or similar events. We believe that unambiguous non-sarcastic sentences provided the classifier with the ground-truth polarity of those events, which the classifier could then contrast with the opposite estimations in sarcastic sentences. Twitter is a more suitable resource for this purpose than blog posts, because the polarity of short tweets is easier to detect (as all the information necessary to detect polarity is likely to be contained in the same sentence) and because the Twitter API makes it easy to collect a large corpus of tweets containing both sarcastic and non-sarcastic examples of the same event.\nSometimes, however, just knowing the ground truth or simple facts on the topic is not enough, as the text may refer to other events in order to express sarcasm. For example, the sentence “If Hillary wins, she will surely be pleased to recall Monica each time she enters the Oval Office :P :D”, which refers to the 2016 US presidential election campaign and to the events of early 1990's related to the US president Clinton, is sarcastic because Hillary, a candidate and Clinton's wife, would in fact not be pleased to recall her husband's alleged past affair with Monica Lewinsky. The system, however, would need a considerable amount of facts, commonsense knowledge, anaphora resolution, and logical reasoning to draw such a conclusion. In this paper, we will not deal with such complex cases.\nExisting works on sarcasm detection have mainly focused on unigrams and the use of emoticons BIBREF1 , BIBREF2 , BIBREF3 , unsupervised pattern mining approach BIBREF4 , semi-supervised approach BIBREF5 and n-grams based approach BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 with sentiment features. Instead, we propose a framework that learns sarcasm features automatically from a sarcasm corpus using a convolutional neural network (CNN). We also investigate whether features extracted using the pre-trained sentiment, emotion and personality models can improve sarcasm detection performance. Our approach uses relatively lower dimensional feature vectors and outperforms the state of the art on different datasets. In summary, the main contributions of this paper are the following:\nThe rest of the paper is organized as follows: Section SECREF2 proposes a brief literature review on sarcasm detection; Section SECREF4 presents the proposed approach; experimental results and thorough discussion on the experiments are given in Section SECREF5 ; finally, Section SECREF6 concludes the paper.\nNamely, we used Twitter data crawled in a time period, which likely contain both the sarcastic and non-sarcastic accounts of an event or similar events.",

However, besides CIFAR10 dataset, we also evaluated our proposed model with representative baseline methods on multiple imbalanced datasets created from CIFAR10 and SVHN datasets and reported related results in Appendix A.6. In our revised version, we conducted performance comparison on two imbalanced CIFAR100 datasets and added new experiment results in Appendix A.6.3. Comparing with baseline methods, our SRAT method improved the trained model's performance on two imbalanced CIFAR100 datasets clearly, especially for the SRAT-CE and SRAT-Focal variant. Hence, based on all experimental results, we conclude that our SRAT method is able to facilitate the reweighting strategy in adversarial training under imbalanced scenarios.",
        "evidence": "Table 3 and Table 4 show the performance comparison on two imbalanced CIFAR10 datasets. We use bold values to denote the highest accuracy among all methods and use the underline values to indicate our SRAT variants which achieve the highest accuracy among their corresponding baseline methods utilizing the same loss function for making predictions. From Table 3 and Table 4, we get similar observation that, comparing with baseline methods, our proposed SRAT method can produce a robust model which can achieve improved overall performance when the training dataset is imbalanced. In addition, based on the experimental results in Table 3 to Table 4, we find that, compared with the performance improvement between DRCB-LDAM and SRAT-LDAM, the improvement between DRCB-CE and SRAT-CE and the improvement between DRCB-Focal and SRAT-Focal are more obviously. The possible reason behind this phenomenon is, the LDAM loss can also implicitly produce a more separable feature space (Cao et al., 2019) while CE loss and Focal loss do not conduct any specific operations on the latent feature space. Hence, the feature separation loss contained in SRAT-CE and SRAT-Focal could be more effective on learning separable feature space and facilitate the Focal loss on prediction. However, in SRAT-LDAM, the feature separation loss and LDAM loss may affect each other on learning feature representations and, hence, the effectiveness of the feature separation loss may be counteracted or weakened.",

        "answer": "Maria Liakata and Dong Nguyen.",
        "evidence": "In June 2015, the operators of the online discussion site Reddit banned several communities under new anti-harassment rules. BIBREF0 used this opportunity to combine rich online data with computational methods to study a current question: Does eliminating these “echo chambers” diminish the amount of hate speech overall? Exciting opportunities like these, at the intersection of “thick” cultural and societal questions on the one hand, and the computational analysis of rich textual data on larger-than-human scales on the other, are becoming increasingly common.\nIndeed, computational analysis is opening new possibilities for exploring challenging questions at the heart of some of the most pressing contemporary cultural and social issues. While a human reader is better equipped to make logical inferences, resolve ambiguities, and apply cultural knowledge than a computer, human time and attention are limited. Moreover, many patterns are not obvious in any specific context, but only stand out in the aggregate. For example, in a landmark study, BIBREF1 analyzed the authorship of The Federalist Papers using a statistical text analysis by focusing on style, based on the distribution of function words, rather than content. As another example, BIBREF2 studied what defines English haiku and showed how computational analysis and close reading can complement each other. Computational approaches are valuable precisely because they help us identify patterns that would not otherwise be discernible.\nYet these approaches are not a panacea. Examining thick social and cultural questions using computational text analysis carries significant challenges. For one, texts are culturally and socially situated. They reflect the ideas, values and beliefs of both their authors and their target audiences, and such subtleties of meaning and interpretation are difficult to incorporate in computational approaches. For another, many of the social and cultural concepts we seek to examine are highly contested — hate speech is just one such example. Choices regarding how to operationalize and analyze these concepts can raise serious concerns about conceptual validity and may lead to shallow or obvious conclusions, rather than findings that reflect the depth of the questions we seek to address.\nThese are just a small sample of the many opportunities and challenges faced in computational analyses of textual data. New possibilities and frustrating obstacles emerge at every stage of research, from identification of the research question to interpretation of the results. In this article, we take the reader through a typical research process that involves measuring social or cultural concepts using computational methods, discussing both the opportunities and complications that often arise. In the Reddit case, for example, hate speech is measured, however imperfectly, by the presence of particular words semi-automatically extracted from a machine learning algorithm. Operationalizations are never perfect translations, and are often refined over the course of an investigation, but they are crucial.\nWe begin our exploration with the identification of research questions, proceed through data selection, conceptualization, and operationalization, and end with analysis and the interpretation of results. The research process sounds more or less linear this way, but each of these phases overlaps, and in some instances turns back upon itself. The analysis phase, for example, often feeds back into the original research questions, which may continue to evolve for much of the project. At each stage, our discussion is critically informed by insights from the humanities and social sciences, fields that have focused on, and worked to tackle, the challenges of textual analysis—albeit at smaller scales—since their inception.\nIn describing our experiences with computational text analysis, we hope to achieve three primary goals. First, we aim to shed light on thorny issues not always at the forefront of discussions about computational text analysis methods. Second, we hope to provide a set of best practices for working with thick social and cultural concepts. Our guidance is based on our own experiences and is therefore inherently imperfect. Still, given our diversity of disciplinary backgrounds and research practices, we hope to capture a range of ideas and identify commonalities that will resonate for many. And this leads to our final goal: to help promote interdisciplinary collaborations. Interdisciplinary insights and partnerships are essential for realizing the full potential of any computational text analysis that involves social and cultural concepts, and the more we are able to bridge these divides, the more fruitful we believe our work will be.\nThis article is a result of a workshop organized in 2017 by Maria Liakata and Dong Nguyen at the Alan Turing Institute on “Bridging disciplines in analysing text as social and cultural data”.",

        "evidence": "Datasets: We use two recent benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . These two datasets are created to avoid reversible relation problems, thus the prediction task becomes more realistic and hence more challenging BIBREF18 . Table TABREF7 presents the statistics of WN18RR and FB15k-237.\nEvaluation protocol: Following BIBREF3 , for each valid test triple INLINEFORM0 , we replace either INLINEFORM1 or INLINEFORM2 by each of all other entities to create a set of corrupted triples. We use the “Filtered” setting protocol BIBREF3 , i.e., not taking any corrupted triples that appear in the KG into accounts. We rank the valid test triple and corrupted triples in descending order of their scores. We employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions). Lower MR, higher MRR or higher Hits@10 indicate better performance. Final scores on the test set are reported for the model obtaining the highest Hits@10 on the validation set.\nTraining protocol: We use the common Bernoulli strategy BIBREF20 , BIBREF21 when sampling invalid triples. For WN18RR, BIBREF22 found a strong evidence to support the necessity of a WordNet-related semantic setup, in which they averaged pre-trained word embeddings for word surface forms within the WordNet to create synset embeddings, and then used these synset embeddings to initialize entity embeddings for training their TransE association model. We follow this evidence in using the pre-trained 100-dimensional Glove word embeddings BIBREF23 to train a TransE model on WN18RR.\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 . For ConvKB, we use a new process of training up to 100 epochs and monitor the Hits@10 score after every 10 training epochs to choose optimal hyper-parameters with the Adam initial learning rate in INLINEFORM0 and the number of filters INLINEFORM1 in INLINEFORM2 . We obtain the highest Hits@10 scores on the validation set when using N= 400 and the initial learning rate INLINEFORM3 on WN18RR; and N= 100 and the initial learning rate INLINEFORM4 on FB15k-237.\nLike in ConvKB, we use the same pre-trained entity and relation embeddings produced by TransE to initialize entity and relation embeddings in our CapsE for both WN18RR and FB15k-237 ( INLINEFORM0 ). We set the batch size to 128, the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM1 ), and the number of iterations in the routing algorithm INLINEFORM2 in INLINEFORM3 . We run CapsE up to 50 epochs and monitor the Hits@10 score after each 10 training epochs to choose optimal hyper-parameters. The highest Hits@10 scores for our CapsE on the validation set are obtained when using INLINEFORM4 , INLINEFORM5 and the initial learning rate at INLINEFORM6 on WN18RR; and INLINEFORM7 , INLINEFORM8 and the initial learning rate at INLINEFORM9 on FB15k-237.\nDataset: We use the SEARCH17 dataset BIBREF12 of query logs of 106 users collected by a large-scale web search engine. A log entity consists of a user identifier, a query, top-10 ranked documents returned by the search engine and clicked documents along with the user's dwell time. BIBREF12 constructed short-term (session-based) user profiles and used the profiles to personalize the returned results. They then employed the SAT criteria BIBREF26 to identify whether a returned document is relevant from the query logs as either a clicked document with a dwell time of at least 30 seconds or the last clicked document in a search session (i.e., a SAT click). After that, they assigned a INLINEFORM0 label to a returned document if it is a SAT click and also assigned INLINEFORM1 labels to the remaining top-10 documents. The rank position of the INLINEFORM2 labeled documents is used as the ground truth to evaluate the search performance before and after re-ranking.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set BIBREF12 . The training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.\nEvaluation protocol: Our CapsE is used to re-rank the original list of documents returned by a search engine as follows: (i) We train our model and employ the trained model to calculate the score for each INLINEFORM0 triple. (ii) We then sort the scores in the descending order to obtain a new ranked list. To evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1. For each metric, the higher value indicates better ranking performance.\nWe compare CapsE with the following baselines using the same experimental setup: (1) SE: The original rank is returned by the search engine. (2) CI BIBREF27 : This baseline uses a personalized navigation method based on previously clicking returned documents. (3) SP BIBREF9 , BIBREF11 : A search personalization method makes use of the session-based user profiles. (4) Following BIBREF12 , we use TransE as a strong baseline model for the search personalization task. Previous work shows that the well-known embedding model TransE, despite its simplicity, obtains very competitive results for the knowledge graph completion BIBREF28 , BIBREF29 , BIBREF14 , BIBREF30 , BIBREF15 . (5) The CNN-based model ConvKB is the most closely related model to our CapsE.\nEmbedding initialization: We follow BIBREF12 to initialize user profile, query and document embeddings for the baselines TransE and ConvKB, and our CapsE.\nWe train a LDA topic model BIBREF31 with 200 topics only on the relevant documents (i.e., SAT clicks) extracted from the query logs. We then use the trained LDA model to infer the probability distribution over topics for every returned document. We use the topic proportion vector of each document as its document embedding (i.e. INLINEFORM0 ). In particular, the INLINEFORM1 element ( INLINEFORM2 ) of the vector embedding for document INLINEFORM3 is: INLINEFORM4 where INLINEFORM5 is the probability of the topic INLINEFORM6 given the document INLINEFORM7 .\nWe also represent each query by a probability distribution vector over topics. Let INLINEFORM0 be the set of top INLINEFORM1 ranked documents returned for a query INLINEFORM2 (here, INLINEFORM3 ). The INLINEFORM4 element of the vector embedding for query INLINEFORM5 is defined as in BIBREF12 : INLINEFORM6 , where INLINEFORM7 is the exponential decay function of INLINEFORM8 which is the rank of INLINEFORM9 in INLINEFORM10 . And INLINEFORM11 is the decay hyper-parameter ( INLINEFORM12 ). Following BIBREF12 , we use INLINEFORM13 . Note that if we learn query and document embeddings during training, the models will overfit to the data and will not work for new queries and documents. Thus, after the initialization process, we fix (i.e., not updating) query and document embeddings during training for TransE, ConvKB and CapsE.\nIn addition, as mentioned by BIBREF9 , the more recently clicked document expresses more about the user current search interest. Hence, we make use of the user clicked documents in the training set with the temporal weighting scheme proposed by BIBREF11 to initialize user profile embeddings for the three embedding models.\nHyper-parameter tuning: For our CapsE model, we set batch size to 128, and also the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM0 ). The number of iterations in the routing algorithm is set to 1 ( INLINEFORM1 ). For the training model, we use the Adam optimizer with the initial learning rate INLINEFORM2 INLINEFORM3 INLINEFORM4 INLINEFORM5 INLINEFORM6 INLINEFORM7 . We also use ReLU as the activation function INLINEFORM8 . We select the number of filters INLINEFORM9 . We run the model up to 200 epochs and perform a grid search to choose optimal hyper-parameters on the validation set. We monitor the MRR score after each training epoch and obtain the highest MRR score on the validation set when using INLINEFORM10 and the initial learning rate at INLINEFORM11 .\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 and then follow their training protocols to tune hyper-parameters for TransE and ConvKB, respectively. We also monitor the MRR score after each training epoch and attain the highest MRR score on the validation set when using margin = 5, INLINEFORM0 -norm and SGD learning rate at INLINEFORM1 for TransE; and INLINEFORM2 and the Adam initial learning rate at INLINEFORM3 for ConvKB.\nWe employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions).",

This jealousy grew as she became more and more beautiful and kin with each passing day. \n\nThere was one person who was the most jealous of all. Her name was Hilda. She lived outside of town in an abandon shack. It was rumored she had magical powers that she would use for evil. One day she decided to user her magic trap the princess.\n\nOne day the princess was was walking in the forest and came upon a small cave. She hadn't noticed this cave before as this was her favorite area to explore. She was surprised to see it but also quite happy as she loved to find new things on her long walks. She could see something sparkling inside the cave. She was drawn to the pretty colors and what looked like gold and silver.\n\nShe crawled into the cave, however when she did so she saw had been tricked and the cage with the gold and silver was just an illusion. She had actually walked into a giant cage. Hilda had tricked her! She began to cry for she did not know how she would get out of this situation.\n\nDays passed and the princess was becoming very worried and sad that no one would ever find her.\n\nLuckily, there was a friendly troll who lived in a neighboring part of the forest. One day he was out gathering mushrooms for his dinner that night when he heard a small whimpering coming from Hilda's home. He looked in the window and saw the princess. He gasped in disbelief. He decided he had to come up with a plan to save her.\n\nHe was very knowledgeable about plans in the forest and their secret powers. He knew of certain mushrooms that could cast a spell on a person and make them very drowsy. He decided he would slip one of these in Hilda's food so she would fall asleep and he could free the princess.\n\nThe next day while Hilda was taking a bath, he snuck into the house and dropped some of the mushrooms into the soup she was brewing on the stove. he quickly went outside to then hide in the bushes and watch to see what would happen.\n\nHilda came out after taking her bath and getting ready. She laughed as she saw the sad princess in her cage. She then began to pour herself a little bowl of soup for breakfast. After taking a few sips she began to feel very very sleepy. She decided she must lay down at once. \n\nIt had worked! The troll was delighted and quickly entered the house. However, he realized once inside that he did not know where the key was to the cage! The princess whispered that Hilda often kept it in her pocket. \"Oh no!\" he thought. He hadn't thought this through and if he reached into Hilda's pocket he ran the risk of waking her up at which point she would surely cast a spell on him and he and the princess would be doomed.\n\nHe crept quietly toward her. Her pockets were covered by her arms. He lifted one gently. She snored a bit and turned over. It scared him but she seemed to still be asleep. he tried again. This time being more quiet. He was able to get the key out. Success! He quickly went over to the cage and was able to free the princess!\n\nShe returned home to her village and told everyone what a hero the Troll was.

        "question": "Is the pre-initialization mechanism they propose a single-layer one?",
        "answer": "No,it's a two-layer one.",
        "evidence": "Speech input is now a common feature for smart devices. In many cases, the user's query involves entities such as a name from a contact list, a location, or a music title. Recognizing entities is particularly challenging for speech recognition because many entities are infrequent or out of the main vocabulary of the system. One way to improve performance is such cases is through the use of a personal language model (LM) which contains the expected user-specific entities. Because each user can have their own personalized LM, it is vital that the speech decoder be able to efficiently load the model on the fly, so it can be used in decoding, without any noticeable increase in latency.\nMany state-of-the-art speech recognition decoders are based on the weighted finite state transducer (WFST) paradigm BIBREF0, BIBREF1. A conventional WFST decoder searches a statically composed $H C L G$ graph, where $H$ is the graph that translates HMM states to CD phones, $C$ translates CD phones to graphemes, $L$ translates graphemes to words and $G$ is graph that represents the language model. Using a statically composed graph has two limitations. First, it is both compute and memory intensive when the vocabulary and LM are large. Second, the static graph approach makes it hard to handle personalized language models BIBREF2. Many common tasks a user may want to perform with a voice assistant such as making phone calls, messaging to a specific contact or playing favorite music require a personalized language model. A dynamic WFST decoder is better suited for such cases. As denoted in Eq (DISPLAY_FORM1), in a dynamic WFST decoder, $HCL$ is composed and optimized offline, while $G$ is composed on the fly with lazy (on-demand) composition, denoted as $\\circ $.\nTo handle dynamic entities, a class LM $G_c$ is normally used as background $G$ and a personalized LM $G_p$ is replaced on-the-fly, before applying lazy composition.\nSince the non-terminal states are composed on-the-fly, it means the states of recognition FST will also contain personalized information that cannot be used by other users or service threads.\nIn previous work, a method was proposed to do a pre-initialized composition for a non-class LM BIBREF3. However, it the dynamic part is still expanded on-the-fly. In this work, we propose two improvements in order to best leverage class language models. First, we use simpler methods for pre-initialization which do not need to pre-generate decoder state statistics. Second, we propose a two-layer pre-initialization mechanism that also avoids performing dynamic expansion on per user basis. In the two-layer pre-initialization method, we make use of a class LM with class tag. We build a personalized FST that contains the members of the class for each user. Using the FST replacement algorithm, we obtain a personalized language transducer BIBREF4. We perform a pre-composition for all FST states whose transitions do not contain class tags. By doing so, the actual on-demand composition is only required for the states in personalized FST. For a multi-threaded service, the pre-composed FST can be shared by all threads, since it does not contain personalized FST states (non-terminals). The personalized part will be shared for all utterances from the same user, which will take full advantage of memory usage.\nUnlike the previous pre-initialization approach that is based on calculating the state statistics BIBREF3, our simplified pre-initialization methods do not rely on pre-calculated state frequencies. Instead, we directly expand the graph with breadth-first search or through a data-driven approach where a small numbers of utterances are processed by the decoder offline. We found that both methods are effective, but the data-driven approach outperforms the breadth first search algorithm. Both methods can be combined to achieve the best performance. Through a series of experiments on a speech recognition task for the calling domain, we found that pre-initialization on the public graph speeds up the decoding time by a factor of three. Futhermore, sharing the private graph further reduces decoding time and results in factor of five improvement in efficiency.\nSecond, we propose a two-layer pre-initialization mechanism that also avoids performing dynamic expansion on per user basis.",

        "evidence": "Extensive work exists on knowledge graph embeddings dating back to Nickel, Tresp, and Kriegel ( BIBREF1 ) who first proposed Rescal based on a matrix factorization approach. Bordes et al. ( BIBREF2 ) advanced this line of work by proposing the first translational model TransE which seeks to relate the head and tail entity embeddings by modeling the relation as a translational vector. This culminated in a long series of new knowledge graph embeddings all based on the translational principle with various refinements BIBREF9 , BIBREF10 , BIBREF4 , BIBREF3 , BIBREF5 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 . Some recently proposed models like ManiFoldE BIBREF17 attempt to learn knowledge graph embeddings as a manifold while embeddings like HolE BIBREF1 derive inspiration from associative memories. Furthermore, with the success of neural models, models based on convolutional neural networks have been proposed like BIBREF6 , BIBREF18 to learn knowledge graph embeddings. Other models in this class of models include ConvKB BIBREF19 and KBGAN BIBREF20 . There has been some work on incorporating additional information like entity types, relation paths etc. to learn knowledge graph representations. Palumbo et al. ( BIBREF21 ) use node2vec to learn embeddings of entities and items in a knowledge graph. A notable class of methods called “path-ranking” based models directly model paths between entities as features. Examples include Path Ranking Algorithm (PRA) BIBREF22 , PTransE BIBREF10 and models based on recurrent neural networks BIBREF23 , BIBREF24 . Besides, Das et al. ( BIBREF25 ) propose a reinforcement learning method that addresses practical task of answering questions where the relation is known, but only one entity. Hartford et al. ( BIBREF26 ) model interactions across two or more sets of objects using a parameter-sharing scheme. While most of the above models except for the recurrent-neural net abased models above are shallow our model Dolores differs from all of these works and especially that of Palumbo et al. ( BIBREF21 ) in that we learn deep contextualized knowledge graph representations of entities and relations using a deep neural sequential model. The work that is closest to our work is that of Das et al. ( BIBREF24 ) who directly use an RNN-based architecture to model paths to predict missing links. We distinguish our work from this in the following key ways: (a) First, unlike Das et al. ( BIBREF24 ), our focus is not on path reasoning but on learning rich knowledge graph embeddings useful for a variety of predictive tasks. Moreover while Das et al. ( BIBREF24 ) need to use paths generated from PRA that typically correlate with relations, our method has no such restriction and only uses paths generated by generic random walks greatly enhancing the scalability of our method. In fact, we incorporate Dolores embeddings to improve the performance of the model proposed by Das et al. ( BIBREF24 ). (b) Second, and most importantly we learn knowledge graph embeddings at multiple layers each potentially capturing different levels of abstraction. (c) Finally, while we are inspired by the work of Peters et al. ( BIBREF8 ) in learning deep word representations, we build on their ideas by drawing connections between knowledge graphs and language modeling BIBREF8 . In particular, we propose methods to use random walks over knowledge graphs in conjunction with the machinery of deep neural language modeling to learn powerful deep contextualized knowledge graph embeddings that improve the state of the art on various knowledge graph tasks.\nWe distinguish our work from this in the following key ways: (a) First, unlike Das et al., our focus is not on path reasoning but on learning rich knowledge graph embeddings useful for a variety of predictive tasks.

In addition to this, the consumption of information has dramatically changed: more and more people directly access information through social media platforms (e.g. Facebook and Twitter), and are less and less exposed to a diversity of perspectives and opinions. The combination of these factors may easily result in information overload and impenetrable “filter bubbles”. Events, i.e. things that happen or hold as true in the world, are the basic components of such data stream. Being able to correctly identify and classify them plays a major role to develop robust solutions to deal with the current stream of data (e.g. the storyline framework BIBREF0 ), as well to improve the performance of many Natural Language Processing (NLP) applications such as automatic summarization and question answering (Q.A.).\nEvent detection and classification has seen a growing interest in the NLP community thanks to the availability of annotated corpora BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 and evaluation campaigns BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 .

        "question": "How many datasets do the authors conduct extensive experiments on?",
        "answer": "Five.",
        "evidence": "Neural network based models have been widely exploited with the prosperities of Deep Learning BIBREF0 and achieved inspiring performances on many NLP tasks, such as text classification BIBREF1 , BIBREF2 , semantic matching BIBREF3 , BIBREF4 and machine translation BIBREF5 . These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nWe conduct extensive experiments on five benchmark datasets for text classification.",

        "question": "Give me a list of the key elements of telecommunications developed over time",
        "evidence": "At the 1932 Plenipotentiary Telegraph Conference and the International Radiotelegraph Conference in Madrid, the two organizations decided to merge to form the International Telecommunication Union (ITU). They defined telecommunication as \"any telegraphic or telephonic communication of signs, signals, writing, facsimiles and sounds of any kind, by wire, wireless or other systems or processes of electric signaling or visual signaling (semaphores).\"\n\nThe definition was later reconfirmed, according to Article 1.3 of the Radio Regulations (RR), telecommunication, which defined it as \"Any transmission, emission or reception of signs, signals, writings, images and sounds or intelligence of any nature by wire, radio, optical, or other electromagnetic systems\".\n\nBeacons and pigeons\n\nA replica of one of Chappe's semaphore towers\nHoming pigeons have been used throughout history by different cultures. Pigeon post had Persian roots and was later used by the Romans to aid their military. Frontinus claimed Julius Caesar used pigeons as messengers in his conquest of Gaul. The Greeks also conveyed the names of the victors at the Olympic Games to various cities using homing pigeons. In the early 19th century, the Dutch government used the system in Java and Sumatra. And in 1849, Paul Julius Reuter started a pigeon service to fly stock prices between Aachen and Brussels, a service that operated for a year until the gap in the telegraph link was closed.\n\nIn the Middle Ages, chains of beacons were commonly used on hilltops as a means of relaying a signal. Beacon chains suffered the drawback that they could only pass a single bit of information, so the meaning of the message such as \"the enemy has been sighted\" had to be agreed upon in advance. One notable instance of their use was during the Spanish Armada, when a beacon chain relayed a signal from Plymouth to London.\n\nIn 1792, Claude Chappe, a French engineer, built the first fixed visual telegraphy system (or semaphore line) between Lille and Paris. However semaphore suffered from the need for skilled operators and expensive towers at intervals of ten to thirty kilometres (six to nineteen miles). As a result of competition from the electrical telegraph, the last commercial line was abandoned in 1880.\n\nTelegraph and telephone\nOn July 25, 1837, the first commercial electrical telegraph was demonstrated by English inventor Sir William Fothergill Cooke and English scientist Sir Charles Wheatstone. Both inventors viewed their device as \"an improvement to the  electromagnetic telegraph\" and not as a new device.\n\nSamuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on September 2, 1837. His code was an important advance over Wheatstone's signaling method. The first transatlantic telegraph cable was successfully completed on July 27, 1866, allowing transatlantic telecommunication for the first time.\n\nThe conventional telephone was patented by Alexander Bell in 1876. Elisha Gray also filed a caveat for it in 1876. Gray abandoned his caveat and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had filed his caveat for the variable resistance telephone, but Bell was the first to document the idea and test it in a telephone. Antonio Meucci invented a device that allowed the electrical transmission of voice over a line nearly 30 years before in 1849, but his device was of little practical value because it relied on the electrophonic effect requiring users to place the receiver in their mouths to \"hear.\" The first commercial telephone services were set up by the Bell Telephone Company in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London.\n\nRadio and television\nIn 1894, Italian inventor Guglielmo Marconi began developing a wireless communication using the then-newly discovered phenomenon of radio waves, showing by 1901 that they could be transmitted across the Atlantic Ocean. This was the start of wireless telegraphy by radio. On 17 December 1902, a transmission from the Marconi station in Glace Bay, Nova Scotia, Canada, became the world's first radio message to cross the Atlantic from North America. In 1904, a commercial service was established to transmit nightly news summaries to subscribing ships, which incorporated them into their onboard newspapers.\n\nWorld War I accelerated the development of radio for military communications. After the war, commercial radio AM broadcasting began in the 1920s and became an important mass medium for entertainment and news. World War II again accelerated the development of radio for the wartime purposes of aircraft and land communication, radio navigation, and radar. Development of stereo FM broadcasting of radio began in the 1930s in the United States and the 1970s in the United Kingdom, displacing AM as the dominant commercial standard.\n\nOn March 25, 1925, John Logie Baird demonstrated the transmission of moving pictures at the London department store Selfridges. Baird's device relied upon the Nipkow disk and thus became known as the mechanical television. It formed the basis of experimental broadcasts done by the British Broadcasting Corporation beginning on 30 September 1929. However, for most of the 20th century, televisions depended on the cathode ray tube invented by Karl Braun. The first version of such a television to show promise was produced by Philo Farnsworth and demonstrated to his family on 7 September 1927. After World War II, interrupted experiments resumed and television became an important home entertainment broadcast medium.\n\nThermionic valves\nThe type of device known as a thermionic tube or thermionic valve uses thermionic emission of electrons from a heated cathode for a number of fundamental electronic functions such as signal amplification and current rectification.\n\nThe simplest vacuum tube, the diode invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. Adding one or more control grids within the tube enables the current between the cathode and anode to be controlled by the voltage on the grid or grids. These devices became a key component of electronic circuits for the first half of the 20th century and were crucial to the development of radio, television, radar, sound recording and reproduction, long-distance telephone networks, and analogue and early digital computers. While some applications had used earlier technologies such as the spark gap transmitter for radio or mechanical computers for computing, it was the invention of the thermionic vacuum tube that made these technologies widespread and practical, leading to the creation of electronics.\n\nIn the 1940s, the invention of semiconductor devices made it possible to produce solid-state devices, which are smaller, cheaper, and more efficient, reliable, and durable than thermionic tubes. Starting in the mid-1960s, thermionic tubes were replaced with the transistor. Thermionic tubes still have some applications for certain high-frequency amplifiers.\n\nComputer networks and the Internet\nOn 11 September 1940, George Stibitz transmitted problems for his Complex Number Calculator in New York using a teletype and received the computed results back at Dartmouth College in New Hampshire. This configuration of a centralized computer (mainframe) with remote dumb terminals remained popular well into the 1970s. In the 1960s, researchers started to investigate packet switching, a technology that sends a message in portions to its destination asynchronously without passing it through a centralized mainframe. A four-node network emerged on 5 December 1969, constituting the beginnings of the ARPANET, which by 1981 had grown to 213 nodes. ARPANET eventually merged with other networks to form the Internet. While Internet development was a focus of the Internet Engineering Task Force (IETF) who published a series of Request for Comments documents, other networking advancements occurred in industrial laboratories, such as the local area network (LAN) developments of Ethernet (1983) and Token Ring (1984)[citation needed].\n\nGrowth of transmission capacity\nThe effective capacity to exchange information worldwide through two-way telecommunication networks grew from 281 petabytes (pB) of optimally compressed information in 1986 to 471 pB in 1993 to 2.2 exabytes (eB) in 2000 to 65 eB in 2007. This is the informational equivalent of two newspaper pages per person per day in 1986, and six entire newspapers per person per day by 2007. Given this growth, telecommunications play an increasingly important role in the world economy and the global telecommunications industry was about a $4.7 trillion sector in 2012. The service revenue of the global telecommunications industry was estimated to be $1.5 trillion in 2010, corresponding to 2.4% of the world's gross domestic product (GDP).",

        "evidence": "Sarcasm is defined as “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”. As the fields of affective computing and sentiment analysis have gained increasing popularity BIBREF0 , it is a major concern to detect sarcastic, ironic, and metaphoric expressions. Sarcasm, especially, is key for sentiment analysis as it can completely flip the polarity of opinions. Understanding the ground truth, or the facts about a given event, allows for the detection of contradiction between the objective polarity of the event (usually negative) and its sarcastic characteristic by the author (usually positive), as in “I love the pain of breakup”. Obtaining such knowledge is, however, very difficult.\nIn our experiments, we exposed the classifier to such knowledge extracted indirectly from Twitter. Namely, we used Twitter data crawled in a time period, which likely contain both the sarcastic and non-sarcastic accounts of an event or similar events. We believe that unambiguous non-sarcastic sentences provided the classifier with the ground-truth polarity of those events, which the classifier could then contrast with the opposite estimations in sarcastic sentences. Twitter is a more suitable resource for this purpose than blog posts, because the polarity of short tweets is easier to detect (as all the information necessary to detect polarity is likely to be contained in the same sentence) and because the Twitter API makes it easy to collect a large corpus of tweets containing both sarcastic and non-sarcastic examples of the same event.\nSometimes, however, just knowing the ground truth or simple facts on the topic is not enough, as the text may refer to other events in order to express sarcasm. For example, the sentence “If Hillary wins, she will surely be pleased to recall Monica each time she enters the Oval Office :P :D”, which refers to the 2016 US presidential election campaign and to the events of early 1990's related to the US president Clinton, is sarcastic because Hillary, a candidate and Clinton's wife, would in fact not be pleased to recall her husband's alleged past affair with Monica Lewinsky. The system, however, would need a considerable amount of facts, commonsense knowledge, anaphora resolution, and logical reasoning to draw such a conclusion. In this paper, we will not deal with such complex cases.\nExisting works on sarcasm detection have mainly focused on unigrams and the use of emoticons BIBREF1 , BIBREF2 , BIBREF3 , unsupervised pattern mining approach BIBREF4 , semi-supervised approach BIBREF5 and n-grams based approach BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 with sentiment features. Instead, we propose a framework that learns sarcasm features automatically from a sarcasm corpus using a convolutional neural network (CNN). We also investigate whether features extracted using the pre-trained sentiment, emotion and personality models can improve sarcasm detection performance. Our approach uses relatively lower dimensional feature vectors and outperforms the state of the art on different datasets. In summary, the main contributions of this paper are the following:\nThe rest of the paper is organized as follows: Section SECREF2 proposes a brief literature review on sarcasm detection; Section SECREF4 presents the proposed approach; experimental results and thorough discussion on the experiments are given in Section SECREF5 ; finally, Section SECREF6 concludes the paper.\nIn summary, the main contributions of this paper are the following: • To the best of our knowledge, this is the first work on using deep learning for sarcasm detection. • Unlike other works, we exploit sentiment and emotion features for sarcasm detection. As user profiling is also an important factor for detecting sarcastic content, moreover, we use personalitybased features for the first time in the literature. • Pre-trained models are commonly used in computer vision. In the context of natural language processing (NLP), however, they are barely used. Hence, the use of pre-trained models for feature extraction is also a major contribution of this work.",

        "evidence": "We now evaluate LiLi in terms of its predictive performance and strategy formulation abilities.\nData: We use two standard datasets (see Table 4): (1) Freebase FB15k, and (2) WordNet INLINEFORM0 . Using each dataset, we build a fairly large graph and use it as the original KB ( INLINEFORM1 ) for evaluation. We also augment INLINEFORM2 with inverse triples ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ) for each ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) following existing KBC methods.\nParameter Settings. Unless specified, the empirically set parameters (see Table 1) of LiLi are: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 , INLINEFORM4 , INLINEFORM5 , INLINEFORM6 , INLINEFORM7 , INLINEFORM8 , INLINEFORM9 , INLINEFORM10 . For training RL-model with INLINEFORM11 -greedy strategy, we use INLINEFORM12 , INLINEFORM13 , pre-training steps=50000. We used Keras deep learning library to implement and train the prediction model. We set batch-size as 128, max. training epoch as 150, dropout as 0.2, hidden units and embedding size as 300 and learning rate as 5e-3 which is reduced gradually on plateau with factor 0.5 and patience 5. Adam optimizer and early stopping were used in training. We also shuffle INLINEFORM14 in each epoch and adjust class weights inversely proportional to class frequencies in INLINEFORM15 .\nLabeled Dataset Generation and Simulated User Creation. We create a simulated user for each KB to evaluate LiLi. We create the labeled datasets, the simulated user’s knowledge base ( INLINEFORM0 ), and the base KB ( INLINEFORM1 ) from INLINEFORM2 . INLINEFORM3 used as the initial KB graph ( INLINEFORM4 ) of LiLi.\nWe followed BIBREF16 for labeled dataset generation. For Freebase, we found 86 relations with INLINEFORM0 triples and randomly selected 50 from various domains. We randomly shuffle the list of 50 relations, select 25% of them as unknown relations and consider the rest (75%) as known relations. For each known relation INLINEFORM1 , we randomly shuffle the list of distinct triples for INLINEFORM2 , choose 1000 triples and split them into 60% training, 10% validation and 20% test. Rest 10% along with the leftover (not included in the list of 1000) triples are added to INLINEFORM3 . For each unknown relation INLINEFORM4 , we remove all triples of INLINEFORM5 from INLINEFORM6 and add them to INLINEFORM7 . In this process, we also randomly choose 20% triples as test instances for unknown INLINEFORM8 which are excluded from INLINEFORM9 . Note that, now INLINEFORM10 has at least 10% of chosen triples for each INLINEFORM11 (known and unknown) and so, user is always able to provide clues for both cases. For each labeled dataset, we randomly choose 10% of the entities present in dataset triples, remove triples involving those entities from INLINEFORM12 and add to INLINEFORM13 . At this point, INLINEFORM14 gets reduced to INLINEFORM15 and is used as INLINEFORM16 for LiLi. The dataset stats in Table 4 shows that the base KB (60% triples of INLINEFORM17 ) is highly sparse (compared to original KB) which makes the inference task much harder. WordNet dataset being small, we select all 18 relations for evaluation and create labeled dataset, INLINEFORM18 and INLINEFORM19 following Freebase. Although the user may provide clues 100% of the time, it often cannot respond to MLQs and CLQs (due to lack of required triples/facts). Thus, we further enrich INLINEFORM20 with external KB triples.\nGiven a relation INLINEFORM0 and an observed triple ( INLINEFORM1 , INLINEFORM2 , INLINEFORM3 ) in training or testing, the pair ( INLINEFORM4 , INLINEFORM5 ) is regarded as a +ve instance for INLINEFORM6 . Following BIBREF18 , for each +ve instance ( INLINEFORM7 , INLINEFORM8 ), we generate two negative ones, one by randomly corrupting the source INLINEFORM9 , and the other by corrupting the target INLINEFORM10 . Note that, the test triples are not in INLINEFORM11 or INLINEFORM12 and none of the -ve instances overlap with the +ve ones.\nBaselines. As none of the existing KBC methods can solve the OKBC problem, we choose various versions of LiLi as baselines.\nSingle: Version of LiLi where we train a single prediction model INLINEFORM0 for all test relations.\nSep: We do not transfer (past learned) weights for initializing INLINEFORM0 , i.e., we disable LL.\nF-th): Here, we use a fixed prediction threshold 0.5 instead of relation-specific threshold INLINEFORM0 .\nBG: The missing or connecting links (when the user does not respond) are filled with “@-RelatedTo-@\" blindly, no guessing mechanism.\nw/o PTS: LiLi does not ask for additional clues via past task selection for skillset improvement.\nEvaluation Metrics. To evaluate the strategy formulation ability, we introduce a measure called Coverage( INLINEFORM0 ), defined as the fraction of total query data instances, for which LiLi has successfully formulated strategies that lead to winning. If LiLi wins on all episodes for a given dataset, INLINEFORM1 is 1.0. To evaluate the predictive performance, we use Avg. MCC and avg. +ve F1 score.\nTo evaluate the strategy formulation ability, we introduce a measure called Coverage(C), defined as the fraction of total query data instances, for which LiLi has successfully formulated strategies that lead to winning.

So, we actually include four models in our experiments (having a projected layer or not). Firstly, LastStateRNN is the classic RNN model, where the last state passes through an MLP and then the LR Layer estimates the corresponding probability. In contrast, in the AvgRNN model we consider the average vector of all states that come out of the cells. The AttentionRNN model is the one that it has been presented in BIBREF9. Moreover, we introduce the MultiAttentionRNN model for the harassment language detection, which instead of one attention, it includes four attentions, one for each category.\nWe have evaluated our models considering the F1 Score, which is the harmonic mean of precision and recall. We have run ten times the experiment for each model and considered the average F1 Score. The results are mentioned in Table TABREF11. Considering F1 Macro the models that include the multi-attention mechanism outperform the others and particularly the one with the Projected Layer has the highest performance.

        "evidence": "Sarcasm is defined as “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”. As the fields of affective computing and sentiment analysis have gained increasing popularity BIBREF0 , it is a major concern to detect sarcastic, ironic, and metaphoric expressions. Sarcasm, especially, is key for sentiment analysis as it can completely flip the polarity of opinions. Understanding the ground truth, or the facts about a given event, allows for the detection of contradiction between the objective polarity of the event (usually negative) and its sarcastic characteristic by the author (usually positive), as in “I love the pain of breakup”. Obtaining such knowledge is, however, very difficult.\nIn our experiments, we exposed the classifier to such knowledge extracted indirectly from Twitter. Namely, we used Twitter data crawled in a time period, which likely contain both the sarcastic and non-sarcastic accounts of an event or similar events. We believe that unambiguous non-sarcastic sentences provided the classifier with the ground-truth polarity of those events, which the classifier could then contrast with the opposite estimations in sarcastic sentences.

        "evidence": "Suppose a user wants to write a sentence “I will be 10 minutes late.” Ideally, she would type just a few keywords such as “10 minutes late” and an autocomplete system would be able to infer the intended sentence (Figure FIGREF1). Existing left-to-right autocomplete systems BIBREF0, BIBREF1 can often be inefficient, as the prefix of a sentence (e.g. “I will be”) fails to capture the core meaning of the sentence. Besides the practical goal of building a better autocomplete system, we are interested in exploring the tradeoffs inherent to such communication schemes between the efficiency of typing keywords, accuracy of reconstruction, and interpretability of keywords.\nOne approach to learn such schemes is to collect a supervised dataset of keywords-sentence pairs as a training set, but (i) it would be expensive to collect such data from users, and (ii) a static dataset would not capture a real user's natural predilection to adapt to the system BIBREF2. Another approach is to avoid supervision and jointly learn a user-system communication scheme to directly optimize the combination of efficiency and accuracy. However, learning in this way can lead to communication schemes that are uninterpretable to humans BIBREF3, BIBREF4 (see Appendix for additional related work).\nIn this work, we propose a simple, unsupervised approach to an autocomplete system that is efficient, accurate, and interpretable. For interpretability, we restrict keywords to be subsequences of their source sentences based on the intuition that humans can infer most of the original meaning from a few keywords. We then apply multi-objective optimization approaches to directly control and achieve desirable tradeoffs between efficiency and accuracy.\nWe observe that naively optimizing a linear combination of efficiency and accuracy terms is unstable and leads to suboptimal schemes. Thus, we propose a new objective which optimizes for communication efficiency under an accuracy constraint. We show this new objective is more stable and efficient than the linear objective at all accuracy levels.\nAs a proof-of-concept, we build an autocomplete system within this framework which allows a user to write sentences by specifying keywords. We empirically show that our framework produces communication schemes that are 52.16% more accurate than rule-based baselines when specifying 77.37% of sentences, and 11.73% more accurate than a naive, weighted optimization approach when specifying 53.38% of sentences. Finally, we demonstrate that humans can easily adapt to the keyword-based autocomplete system and save nearly 50% of time compared to typing a full sentence in our user study.\nWe then apply multi-objective optimization approaches to directly control and achieve desirable tradeoffs between efficiency and accuracy.",

CTC loss BIBREF8 is then computed from the timestep-wise probabilities.\nA base model, INLINEFORM0 , is trained on 190 hours ( INLINEFORM1 100K instances) of transcribed speech data. Then, it selects a subset of a 1,700-hour ( INLINEFORM2 1.1M instances) unlabeled dataset. We query labels for the selected subset and incorporate them into training. Learning rates are tuned on a small validation set of 2048 instances.

Specifically, from the probabilities over the characters, we can compute an entropy per timestep and then average them. This method is denoted as entropy. We could also take the most likely prediction and calculate its CTC loss, normalized by number of timesteps. This method is denoted as pCTC (predicted CTC) in the following sections.\nWe implement EGL by marginalizing over the most likely 100 labels, and compare it with: 1) a random selection baseline, 2) entropy, and 3) pCTC.

        "evidence": "As can be seen in Figure FIGREF15, in some areas the domains are somewhat overlapping in the embedding space, which may lead to outlier cases where examples from one domain are assigned to a cluster of a another domain. We plot a confusion matrix (Figure FIGREF20) to analyze this further based on the clustering with BERT-base and k=5. We first note that the outlier sentences are much shorter than the average sentence length in the corpus (11.62 tokens on average for outliers vs. 20.5 tokens on average in general). This makes sense as shorter sentences contain less information, making it harder to assign them to an appropriate cluster. Table TABREF19 shows examples of outlier sentences, assigned to clusters of domains different from their originating domain. We can see that in many cases the assignments are sensible – for example for sentences originating from the subtitles corpus, a sentence that mentions “great priest” is assigned to the Koran cluster, a sentence that mentions “The International Criminal Court in The Hague” is assigned to the Law cluster, a sentence that mentions “the virus” is assigned to the Medical cluster and so on. This strengthens our claim that defining domains based on the corpus they originated from may be over-simplistic, and using a more data-driven approach may enable to find better domain assignments across different corpora.\nThe domain that attracted the largest number of outliers is the IT domain cluster, with 597 sentences assigned to it from other domains. Looking more closely we find that more than half of these sentences (340 out of 597) included numbers (e.g. “34% 25% 34%” (from medical), “(b) reference number 20 is deleted;” (from law), “(Command of Prostration # 1)” (from Koran) or “The message, R2.” (from subtitles)). As numbers appear in many different contexts, they may be harder to assign to a specific domain by the context-aware language models in such short sentences. The second largest attractor of outliers is the Subtitles cluster, with 372 sentences assigned to it from other domains. We find that most of these sentences contain personal pronouns or question marks (228 out of 372, 61.2%) while the ratio of such sentences in the entire corpus is only 40%. Examples include “Why did you choose the name & amarok;?” (from IT), or “What is Avonex?” (from Medical). This may be expected as the subtitles corpus mainly includes transcriptions of spoken, conversational language, and “conversation tends to have more verbs, more personal pronouns, and more questions” BIBREF25. Another possible reason for the subtitles domain to attract outliers is the fact that this is the least-topical cluster: movies and TV series may discuss diverse topics, unlike medical, religious, legal and technical texts that may have a more cohesive topic.\nWe perform an analysis on the selected datasets, where we measure the precision and recall of sentence selection with respect to the oracle selection. The results are available in Table TABREF34. As also reflected in the BLEU scores, the Domain-Finetune method resulted in the highest domain recall with a minimum of 97.5, while Moore-Lewis and Domain-Cosine scored 89.4 and 78.8 respectively. We find these results very appealing given that only 2000 in-domain sentences were used for selection for each domain out of 1.45 million sentences. Also note that we used DistilBERT in these experiments: we believe that using larger, non-distilled models may result in even better selection performance (although at the price of larger computational requirements).\npx\nAlso note that we used DistilBERT in these experiments: we believe that using larger, nondistilled models may result in even better selection performance (although at the price of larger com_x0002_putational requirements).",

QA tasks on images BIBREF0 have been widely studied, but most focused on understanding text documents BIBREF1 . A representative dataset in text QA is SQuAD BIBREF1 , in which several end-to-end neural models have accomplished promising performance BIBREF2 . Although there is a significant progress in machine comprehension (MC) on text documents, MC on spoken content is a much less investigated field. In spoken question answering (SQA), after transcribing spoken content into text by automatic speech recognition (ASR), typical approaches use information retrieval (IR) techniques BIBREF3 to find the proper answer from the ASR hypotheses. One attempt towards QA of spoken content is TOEFL listening comprehension by machine BIBREF4 . TOEFL is an English examination that tests the knowledge and skills of academic English for English learners whose native languages are not English. Another SQA corpus is Spoken-SQuAD BIBREF5 , which is automatically generated from SQuAD dataset through Google Text-to-Speech (TTS) system. Recently ODSQA, a SQA corpus recorded by real speakers, is released BIBREF6 .\nTo mitigate the impact of speech recognition errors, using sub-word units is a popular approach for speech-related downstream tasks. It has been applied to spoken document retrieval BIBREF7 and spoken term detection BIBREF8 The prior work showed that, using phonectic sub-word units brought improvements for both Spoken-SQuAD and ODSQA BIBREF5 .\nInstead of considering sub-word features, this paper proposes a novel approach to mitigate the impact of ASR errors. We consider reference transcriptions and ASR hypotheses as two domains, and adapt the source domain data (reference transcriptions) to the target domain data (ASR hypotheses) by projecting these two domains in the shared common space. Therefore, it can effectively benefit the SQA model by improving the robustness to ASR errors in the SQA model.\nDomain adaptation has been successfully applied on computer vision BIBREF9 and speech recognition BIBREF10 . It is also widely studied on NLP tasks such as sequence tagging and parsing BIBREF11 , BIBREF12 , BIBREF13 . Recently, adversarial domain adaptation has already been explored on spoken language understanding (SLU).

        "answer": "The Unified Payments Interface is a Peer to Peer payments system launched in India by the National Payments Corporation of India (NPCI) in 2016. NPCI set out with a mandate to change the face of India’s payment systems. It developed the Unified Payments Interface (UPI) as an architecture framework with a set of standard Application Programming Interface (API) specifications to facilitate online payments. The aim was to simplify and provide a single interface across all NPCI systems, thereby creating interoperability and a superior customer experience.\n\nUPI is now one of the most preferred payment solutions in India, with over a billion transactions every month. FY22, the total transaction value processed by the United Payments Interface (UPI) platform accounted for 86% of India’s GDP. UPI’s core function is to support easy and secure money transfers between bank accounts. It does this by adding multiple bank accounts into a single mobile application, allowing for seamless fund transfers and merchant payments from one place. It also enables ‘peer to peer’ and ‘peer to merchant’ collection requests, which can be scheduled and paid as requested.\n\nPayments can be made using a UPI ID, UPI Number, Account number, and an Indian Financial System Code (IFSC). Payment security is as per applicable Reserve Bank of India (RBI) guidelines using a 1-click 2-factor authentication where the second factor of authentication is the UPI PIN. \n\nUPI can be accessed on all major platforms such as Android and iOS with apps developed by members for versions of Android 4.2.2 and iOS 8.1 and above.\n\nThe primary business uses of UPI are to allow a personal mobile as the primary device for all payments, including person to person, person to entity, and entity to person. Using a personal mobile an individual can ‘Pay’ someone (push) as well as ‘Collect’ from\nsomeone (pull). In addition, the ability to pay and collect using ‘UPI IDs’ that are ‘aliases’ to the VPA. The goal is to make  payments by providing an address without having to ever provide account details or credentials on third party applications or websites.\nAlso, sending ‘collect’ requests to others (person to person or entity to person) with a‘pay by’ date, which allows customers to pay at a later date without blocking the money in the account. UPI also allows for pre-authorizing multiple recurring payments (utilities, school fees, subscriptions, etc.) with a one-time secure authentication and rule-based access, similar to ECS. UPI autopay allows customers to set recurring payments for their UPI transactions. Recurring payments up to Indian Rupees 2000 can be set at the frequency desired.\n\nThis makes payments using UPI a fully interoperable system across all PSPs without having silos and closed systems with one-click two-factor authentication, using a personal\nphone, and without any acquiring devices or physical tokens.\n\nIn March 2023, Reserve Bank of India (RBI) and the Monetary Authority of Singapore (MAS) launched the linkage of UPI and Singapore’s PayNow. Remittances from Singapore to India were on track to breach the $100 billion mark in 2023, making it the fourth highest remitting nation to India, accounting for 5.7% of all inbound remittances. Integrating PayNow and UPI will likely reduce charges and the time taken for such transactions.",

Figure FIGREF1), where 6 is the value that was proposed by Vaswani:NIPS2017 for the base model. We investigate what happens in terms of APE performance if we change this setting to 6-6-4 and 6-4-6. To handle out-of-vocabulary words and reduce the vocabulary size, instead of considering words, we consider subword units BIBREF19 by using byte-pair encoding (BPE). In the preprocessing step, instead of learning an explicit mapping between BPEs in the $src$, $mt$ and $pe$, we define BPE tokens by jointly processing all triplets. Thus, $src$, $mt$ and $pe$ derive a single BPE vocabulary. Since $mt$ and $pe$ belong to the same language (German) and $src$ is a close language (English), they naturally share a good fraction of BPE tokens, which reduces the vocabulary size to 28k.\nThe number of layers ($N_{src}$-$N_{mt}$-$N_{pe}$) in all encoders and the decoder for these results is fixed to 6-6-6.

        "question": "Who asked Swami Vivekananda to come to Dakshineswar and in which year?",
        "evidence": "Swami Vivekananda (/ˈswɑːmi ˌvɪveɪˈkɑːnəndə/; Bengali: [ʃami bibekanɔndo] (listen); 12 January 1863 – 4 July 1902), born Narendranath Datta (Bengali: [nɔrendronatʰ dɔto]), was an Indian Hindu monk, philosopher, author, religious teacher, and the chief disciple of the Indian mystic Sri Ramakrishna Paramahansa. He was a key figure in the introduction of Vedanta and Yoga to the Western world and is credited with raising interfaith awareness, and bringing Hinduism to the status of a major world religion. Vivekananda became a popular figure after the 1893 Parliament of Religions in Chicago, where he began his famous speech with the words, \"Sisters and brothers of America...,\" before introducing Hinduism to Americans. He was so impactful at the Parliament that an American newspaper described him as “an orator by divine right and undoubtedly the greatest figure at the Parliament”. After great success at the Parliament, in the subsequent years, Vivekananda delivered hundreds of lectures across the United States, England and Europe, disseminating the core tenets of Hindu philosophy, and founded the Vedanta Society of New York and the Vedanta Society of San Francisco (now Vedanta Society of Northern California), both of which became the foundations for Vedanta Societies in the West.\n\nIn 1881, Narendra first met Ramakrishna, who became his spiritual focus after his own father had died in 1884.\n\nNarendra's first introduction to Ramakrishna occurred in a literature class at General Assembly's Institution when he heard Professor William Hastie lecturing on William Wordsworth's poem, The Excursion. While explaining the word \"trance\" in the poem, Hastie suggested that his students visit Ramakrishna of Dakshineswar to understand the true meaning of trance. This prompted some of his students (including Narendra) to visit Ramakrishna.\n\nThey probably first met personally in November 1881,[note 1] though Narendra did not consider this their first meeting, and neither man mentioned this meeting later. At this time, Narendra was preparing for his upcoming F. A. examination, when Ram Chandra Datta accompanied him to Surendra Nath Mitra's, house where Ramakrishna was invited to deliver a lecture. According to Makarand Paranjape, at this meeting Ramakrishna asked young Narendra to sing. Impressed by his singing talent, he asked Narendra to come to Dakshineshwar.\n\nIn late 1881 or early 1882, Narendra went to Dakshineswar with two friends and met Ramakrishna. This meeting proved to be a turning point in his life. Although he did not initially accept Ramakrishna as his teacher and rebelled against his ideas, he was attracted by his personality and began to frequently visit him at Dakshineswar. He initially saw Ramakrishna's ecstasies and visions as \"mere figments of imagination\" and \"hallucinations\". As a member of Brahmo Samaj, he opposed idol worship, polytheism and Ramakrishna's worship of Kali. He even rejected the Advaita Vedanta of \"identity with the absolute\" as blasphemy and madness, and often ridiculed the idea. Narendra tested Ramakrishna, who faced his arguments patiently: \"Try to see the truth from all angles\", he replied.\n\nNarendra's father's sudden death in 1884 left the family bankrupt; creditors began demanding the repayment of loans, and relatives threatened to evict the family from their ancestral home. Narendra, once a son of a well-to-do family, became one of the poorest students in his college. He unsuccessfully tried to find work and questioned God's existence, but found solace in Ramakrishna and his visits to Dakshineswar increased.\n\nOne day, Narendra requested Ramakrishna to pray to goddess Kali for their family's financial welfare. Ramakrishna instead suggested him to go to the temple himself and pray. Following Ramakrishna's suggestion, he went to the temple thrice, but failed to pray for any kind of worldly necessities and ultimately prayed for true knowledge and devotion from the goddess. Narendra gradually grew ready to renounce everything for the sake of realising God, and accepted Ramakrishna as his Guru.\n\nIn 1885, Ramakrishna developed throat cancer, and was transferred to Calcutta and (later) to a garden house in Cossipore. Narendra and Ramakrishna's other disciples took care of him during his last days, and Narendra's spiritual education continued. At Cossipore, he experienced Nirvikalpa samadhi. Narendra and several other disciples received ochre robes from Ramakrishna, forming his first monastic order. He was taught that service to men was the most effective worship of God. Ramakrishna asked him to care of the other monastic disciples, and in turn asked them to see Narendra as their leader. Ramakrishna died in the early-morning hours of 16 August 1886 in Cossipore.",

        "answer": "A gating mechanism is used to combine the structure and text representations.",
        "evidence": "Knowledge graphs have been proved to benefit many artificial intelligence applications, such as relation extraction, question answering and so on. A knowledge graph consists of multi-relational data, having entities as nodes and relations as edges. An instance of fact is represented as a triplet (Head Entity, Relation, Tail Entity), where the Relation indicates a relationship between these two entities. In the past decades, great progress has been made in building large scale knowledge graphs, such as WordNet BIBREF0 , Freebase BIBREF1 . However, most of them have been built either collaboratively or semi-automatically and as a result, they often suffer from incompleteness and sparseness.\nThe knowledge graph completion is to predict relations between entities based on existing triplets in a knowledge graph. Recently, a new powerful paradigm has been proposed to encode every element (entity or relation) of a knowledge graph into a low-dimensional vector space BIBREF2 , BIBREF3 . The representations of entities and relations are obtained by minimizing a global loss function involving all entities and relations. Therefore, we can do reasoning over knowledge graphs through algebraic computations.\nAlthough existing methods have good capability to learn knowledge graph embeddings, it remains challenging for entities with few or no facts BIBREF4 . To solve the issue of KB sparsity, many methods have been proposed to learn knowledge graph embeddings by utilizing related text information BIBREF5 , BIBREF6 , BIBREF7 . These methods learn joint embedding of entities, relations, and words (or phrases, sentences) into the same vector space. However, there are still three problems to be solved. (1) The combination methods of the structural and textual representations are not well studied in these methods, in which two kinds of representations are merely aligned on word level or separate loss function. (2) The text description may represent an entity from various aspects, and various relations only focus on fractional aspects of the description. A good encoder should select the information from text in accordance with certain contexts of relations. Figure 1 illustrates the fact that not all information provided in its description are useful to predict the linked entities given a specific relation. (3) Intuitively, entities with many facts depend more on well-trained structured representation while those with few or no facts might be largely determined by text descriptions. A good representation should learn the most valuable information by balancing both sides.\nIn this paper, we propose a new deep architecture to learn the knowledge representation by utilizing the existing text descriptions of entities. Specifically, we learn a joint representation of each entity from two information sources: one is structure information, and another is its text description. The joint representation is the combination of the structure and text representations with a gating mechanism. The gate decides how much information from the structure or text representation will carry over to the final joint representation. In addition, we also introduce an attention mechanism to select the most related information from text description under different contexts. Experimental results on link prediction and triplet classification show that our joint models can handle the sparsity problem well and outperform the baseline method on all metrics with a large margin.\nOur contributions in this paper are summarized as follows.\nThe joint representation is the combination of the structure and text representations with a gating mechanism.",

        "question": "What data has been used by them for training a general language model?",
        "answer": "Huge corpus such as an Workshop on Statistical Machine Translation (WMT) data and a movie script data.",
        "evidence": "Recently there has been a considerable interest in language modeling due to various academic and commercial demands. Academically, many studies have investigated this domain such as machine translation, chat-bot, message generation, image tagging and other language-related areas. Commercially, it can be used as a core technology for providing a new application on consumer products or services. For instance, an automatic message-reply prediction service can be launched in mobile devices, thus helping a user to send a reply message when he/she is not provided with a proper input interface.\nTo model the language of human dialogue, a recurrent neural network (RNN) structure is known to show the state of the arts performance with its ability to learn a sequential pattern of the data BIBREF0 . Among the RNN structures, a Long Short-Term Memory RNN (LSTM-RNN) and its variants are successfully used for language modeling tasks BIBREF1 , BIBREF2 . However, as a kind of deep learning technique, the LSTM-RNN and the RNN structure requires both a large number of data and huge computing power to train the model properly. Hence any attempts for applying the RNN structure to personalized language modeling are mainly constrained by the following two limitations. First, personal mobile devices contain private message data among close acquaintances, so users seldom agree to transfer their log out of the devices. This causes a limitation of gathering the whole user data to common computing spaces, where high-performance machines are available. Second, in relatively small computing machines, i.e., smart phone, it is not always-guaranteed to have enough resources to train a deep model within the devices.\nTo resolve these limitations, we propose fast transfer learning schemes. It trains a base model with a large dataset and copies its first n-many layers to the first n-many layers of a target model. Then the target model is fine-tuned with relatively small target data. Several learning schemes such as freezing a certain layer or adding a surplus layer are proposed for achieving the result. In experiments, we trained a general language model with huge corpus such as an Workshop on Statistical Machine Translation (WMT) data and a movie script data by using powerful computing machines, and then transferred the model to target environment for updating to be a personalized language model. With this approach, the final model can mimic target user's language style with proper syntax.\nIn the experiments, we trained the general language model with literary-style data and applied the transfer learning with spoken-style data. Then we evaluated the model output for sentence completion task in a qualitative and a quantitative manner. The test result showed that the model learned the style of the target language properly. Another test was conducted by training the general language model with the script of the drama, “Friends,\" and by applying transfer learning with main character corpora from the script to generate the personalized language model. The message-reply prediction task was evaluated with this model. The test result shows higher similarity between the output of the personalized language model and the same user dialogue than the one between the output of the personalized language model and other users' dialogues.\nThe contributions of this paper are as follows. First, we propose efficient transfer learning schemes for personalized language modeling, which is the first research on transfer learning for RNN based language models with privacy preserving. Second, we show the applicability of our research to the target scenario in the short message reply application by training the model in the similar environment to that of the mobile device, and highlight its test results.\nIn experiments, we trained a general language model with huge corpus such as an Workshop on Statistical Machine Translation (WMT) data1 and a movie script data by using powerful computing machines, and then transferred the model to target environment for updating to be a personalized language model.",

        "answer": "Label propagation for the distant supervision scenario.",
        "evidence": "Internet “trolls” are users of an online community who quarrel and upset people, seeking to sow discord by posting inflammatory content. More recently, organized “troll farms” of political opinion manipulation trolls have also emerged.\nSuch farms usually consist of state-sponsored agents who control a set of pseudonymous user accounts and personas, the so-called “sockpuppets”, which disseminate misinformation and propaganda in order to sway opinions, destabilize the society, and even influence elections BIBREF0.\nThe behavior of political trolls has been analyzed in different recent circumstances, such as the 2016 US Presidential Elections and the Brexit referendum in UK BIBREF0, BIBREF1. However, this kind of analysis requires painstaking and time-consuming manual labor to sift through the data and to categorize the trolls according to their actions. Our goal in the current paper is to automate this process with the help of machine learning (ML). In particular, we focus on the case of the 2016 US Presidential Elections, for which a public dataset from Twitter is available. For this case, we consider only accounts that post content in English, and we wish to divide the trolls into some of the functional categories identified by BIBREF0: left troll, right troll, and news feed.\nWe consider two possible scenarios. The first, prototypical ML scenario is supervised learning, where we want to learn a function from users to categories {left, right, news feed}, and the ground truth labels for the troll users are available. This scenario has been considered previously in the literature by BIBREF2. Unfortunately, a solution for such a scenario is not directly applicable to a real-world use case. Suppose a new troll farm trying to sway the upcoming European or US elections has just been discovered. While the identities of the accounts might be available, the labels to learn from would not be present. Thus, any supervised machine learning approach would fall short of being a fully automated solution to our initial problem.\nA more realistic scenario assumes that labels for troll accounts are not available. In this case, we need to use some external information in order to learn a labeling function. Indeed, we leverage more persistent entities and their labels: news media. We assume a learning scenario with distant supervision where labels for news media are available. By combining these labels with a citation graph from the troll accounts to news media, we can infer the final labeling on the accounts themselves without any need for manual labeling.\nOne advantage of using distant supervision is that we can get insights about the behavior of a newly-discovered troll farm quickly and effortlessly. Differently from troll accounts in social media, which usually have a high churn rate, news media accounts in social media are quite stable. Therefore, the latter can be used as an anchor point to understand the behavior of trolls, for which data may not be available.\nWe rely on embeddings extracted from social media. In particular, we use a combination of embeddings built on the user-to-user mention graph, the user-to-hashtag mention graph, and the text of the tweets of the troll accounts. We further explore several possible approaches using label propagation for the distant supervision scenario.\nAs a result of our approach, we improve the classification accuracy by more than 5 percentage points for the supervised learning scenario. The distant supervision scenario has not previously been considered in the literature, and is one of the main contributions of the paper. We show that even by hiding the labels from the ML algorithm, we can recover 78.5% of the correct labels.\nThe contributions of this paper can be summarized as follows:\nWe predict the political role of Internet trolls (left, news feed, right) in a realistic, unsupervised scenario, where labels for the trolls are not available, and which has not been explored in the literature before.\nWe propose a novel distant supervision approach for this scenario, based on graph embeddings, BERT, and label propagation, which projects the more-commonly-available labels for news media onto the trolls who cited these media.\nWe improve over the state of the art in the traditional, fully supervised setting, where training labels are available.\nWe further explore several possible approaches using label propagation for the distant supervision scenario.",

        "question": "Is the model the first  MRC model with this dual-dynamic capability?",
        "answer": "Yes.",
        "evidence": "The goal of Machine Reading Comprehension (MRC) is to have machines read a text passage and then generate an answer (or select an answer from a list of given candidates) for any question about the passage. There has been a growing interest in the research community in exploring neural MRC models in an end-to-end fashion, thanks to the availability of large-scale datasets, such as CNN/DM BIBREF0 and SQuAD BIBREF1 .\nDespite the variation in model structures, most state-of-the-art models perform reading comprehension in two stages. First, the symbolic representations of passages and questions are mapped into vectors in a neural space. This is commonly achieved via embedding and attention BIBREF2 , BIBREF3 or fusion BIBREF4 . Then, reasoning is performed on the vectors to generate the right answer.\nIdeally, the best attention and reasoning strategies should adapt organically in order to answer different questions. However, most MRC models use a static attention and reasoning strategy indiscriminately, regardless of various question types. One hypothesis is because these models are optimized on those datasets whose passages and questions are domain-specific (or of a single type). For example, in CNN/DM, all the passages are news articles, and the answer to each question is an entity in the passage. In SQuAD, the passages came from Wikipedia articles and the answer to each question is a text span in the article. Such a fixed-strategy MRC model does not adapt well to other datasets. For example, the exact-match score of BiDAF BIBREF2 , one of the best models on SQuAD, drops from 81.5 to 55.8 when applied to TriviaQA BIBREF5 , whereas human performance is 82.3 and 79.7 on SQuAD and TriviaQA, respectively.\nIn real-world MRC tasks, we must deal with questions and passages of different types and complexities, which calls for models that can dynamically determine what attention and reasoning strategy to use for any input question-passage pair on the fly. In a recent paper, BIBREF6 proposed dynamic multi-step reasoning, where the number of reasoning steps is determined spontaneously (using reinforcement learning) based on the complexity of the input question and passage. With a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.\nThe proposed model is called a Dynamic Fusion Network (DFN). In this paper, we describe the version of DFN developed on the RACE dataset BIBREF7 . In RACE, a list of candidate answers is provided for each passage-question pair. So DFN for RACE is a scoring model - the answer candidate with the highest score will be selected as the final answer.\nLike other MRC models, DFNs also perform machine reading in two stages: attention and reasoning. DFN is unique in its use of a dynamic multi-strategy attention process in the attention stage. Here “attention” refers to the process that texts from different sources (passage, question, answers) are combined in the network. In literature, a fixed attention mechanism is usually employed in MRC models. In DFN, the attention strategy is not static; instead, the actual strategy for drawing attention among the three text sources are chosen on the fly for each sample. This lends flexibility to adapt to various question types that require different comprehension skills. The output of the attention stage is then fed into the reasoning module to generate the answer score. The reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.\nInspired by ReasoNet BIBREF6 and dynamic neural module networks BIBREF8 , we use deep reinforcement learning methods BIBREF9 , BIBREF10 to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample. We use RL in favor of other simpler methods (like cascading, pooling or weighted averaging) mainly because we intend to learn a policy that constructs an instance of DFN of a sample-specific structure. Given an input sample consisting of a question, a passage and a list of candidate answers in RACE, an instance of DFN can be constructed via RL step by step on the fly. Such a policy is particularly appealing as it also provides insights on how the model performs on different types of questions. At each decision step, the policy maps its “state”, which represents an input sample, and DFN's partial knowledge of the right answer, to the action of assembling proper attention and reasoning modules for DFN.\nExperiments conducted on the RACE dataset show that DFN significantly outperforms previous state-of-the-art MRC models and has achieved the best result reported on RACE. A thorough empirical analysis also demonstrates that DFN is highly effective in understanding passages of a wide variety of styles and answering questions of different complexities.\nWith a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.",

        "answer": "There are many great trees homeowners in growing region 6 may want to consider for their backyard depending on their priorities. \n\nFirst, the two main types of trees are deciduous, trees that lose their leaves each winter, and evergreen, which retain their foliage year round. Many of the most popular shade trees are deciduous trees, however there are some great evergreen options as well.\n\nStarting with deciduous trees, there are flowering trees and traditional shade trees. Of the traditional shade trees, you may want to consider maples and oaks, of which there are many varieties. Red maples grow a bit slower than silver maples, but have hardier bark, beautiful red leaves in the fall, and a more pleasing traditional branching habit that many prefer vs, Silver maples. Sugar maples growth slower still, but are beautiful, prized trees that turn glowing orange in the fall and produce the sap used in maple syrup come spring. These trees can be 40-70 feet tall at maturity. Oaks are incredibly beautiful trees that are typically a little slower growing than maples, but have strong bark, enabling them to survive harsher conditions and have a long lifespan. They can handle being used as street trees as they do fine with moderate pollution levels and salt from de-icing. You really can't go wrong with maples or oaks as a summer shade tree, with their tall canopies providing wonderful shade once their leaves fill in during the spring.\n\nSome popular flowering options that provide ample shade include cherry and magnolia trees, both of which have beautiful showy spring flowers and reach a height of 20-60 feet at maturity depending on which of the many variants you choose (be careful with this as some are best suited to warmer climates and don't tolerate the cold as well). \n\nFor evergreens, the options are a bit more limited as many of these trees have low canopies that extend all the way to the ground. Many species of spruce and fir tree can have their canopies raised as they mature, creating space underneath for shade. Some pine trees have ample canopy under them, however their thin needle density can limit the amount of shade they provide.\n\nWhichever you ultimately choose, Shade trees add a ton of value to a home and are a great investment. Consider working with an arborist to make the decision based on your lighting and soil conditions. Enlisting a professional's help with planting will ensure your new tree is set up to grow healthy and strong.",

        "answer": "In historical linguistics, transphonologization (also known as rephonologization or cheshirization, see below) is a type of sound change whereby a phonemic contrast that used to involve a certain feature X evolves in such a way that the contrast is preserved, yet becomes associated with a different feature Y.\n\nFor example, a language contrasting two words */sat/ vs. */san/ may evolve historically so that final consonants are dropped, yet the modern language preserves the contrast through the nature of the vowel, as in a pair /sa/ vs. /sã/. Such a situation would be described by saying that a former contrast between oral and nasal consonants has been transphonologized into a contrast between oral and nasal vowels.\n\nThe term transphonologization was coined by André-Georges Haudricourt.

It has a population of around 523, and is often used as a base by mountain climbers preparing to ascend Mount Everest or Cho Oyu. It is known[citation needed] for its views of Mount Everest, Mount Lhotse, Mount Makalu, and Cho Oyu, which comprise four of the six highest mountains in the world.\n\nTingri used to be an important trading post where Sherpas from Nepal exchanged rice, grain and iron for Tibetan wool, livestock and salt. It gives its name to the more than 4,500-meter (14,800 ft)-high broad upland basin that is known as the Tingri Plain. One must cross the pass known as the Lak Pa La (el. 5,220 meters (17,130 ft)) to the north to reach the Tsangpo Valley system. Shallow, fast-flowing rivers of melted snow water make its grassy meadowland ideal for grazing by Tibetan animals. The plain used to abound with gazelles, blue sheep, antelopes and khyang or wild asses but most of the animals are gone now. The Chinese army has a small base nearby.\n\nTingri Lankor (Ding ri glang 'khor) — Padampa's Residence was founded in 1097 CE by the South Indian Buddhist adept, Padampa Sangye (died 1117) who made five visits to Tibet and was an important person in the re-establishment of the Buddhadharma in Tibet. His consort was the Tibetan dakini Machik Labdron. The gompa or temple was built in the Padampa Sange's meditation cave and became the seat of the Dampapa School of Tibetan Buddhism.

Vegetation is more prominent in the thermokarst lowlands to the north of the lake, which are dominated by sedges during the summer. The low-lying areas to the southeast of the lake, and the nearby Creswell Bay, host a Canadian Important Bird Area. The area supports large bird populations during the summer, especially breeding populations of various shorebirds. 13 shorebird species have been observed in the area, while 11 are known to breed there. These species includes the white-rumped sandpiper, red phalarope, black-bellied plover, sanderling, American golden plover, ruddy turnstone, Baird's sandpiper, buff-breasted sandpiper, pectoral sandpiper, semipalmated sandpiper, and red knot. Other birds with populations in the area include the snow goose, king eider, long-tailed duck, northern fulmar, black-legged kittiwake, and peregrine falcon.

He is the husband of Hillary Clinton, who was a U.S. senator from New York from 2001 to 2009, secretary of state from 2009 to 2013 and the Democratic nominee for president in the 2016 presidential election.\n\nClinton was born and raised in Arkansas and attended Georgetown University. He received a Rhodes Scholarship to study at University College, Oxford, and later graduated from Yale Law School. He met Hillary Rodham at Yale; they married in 1975. After graduating from law school, Clinton returned to Arkansas and won election as state attorney general, followed by two non-consecutive tenures as Arkansas governor. As governor, he overhauled the state's education system and served as chairman of the National Governors Association. Clinton was elected president in the 1992 presidential election, defeating incumbent Republican president George H. W. Bush and independent businessman Ross Perot. At 46 years old, he became the third-youngest president of the United States and the first president to be born in the Baby Boomer generation.\n\nClinton presided over the longest period of peacetime economic expansion in American history. He signed into law the North American Free Trade Agreement (NAFTA) and the Violent Crime Control and Law Enforcement Act, but failed to pass his plan for national health care reform. The Republican Party won unified control of Congress for the first time in 40 years in the 1994 elections, but Clinton was still comfortably re-elected in 1996, becoming the first Democrat since Franklin D. Roosevelt to win a second full term. Starting in the mid-1990s, he began an ideological evolution as he became much more conservative in his domestic policy, advocating for and signing the Personal Responsibility and Work Opportunity Act, the State Children's Health Insurance Program and financial deregulation measures. He appointed Ruth Bader Ginsburg and Stephen Breyer to the U.S. Supreme Court. During the last three years of Clinton's presidency, the Congressional Budget Office reported a budget surplus—the first such surplus since 1969. In foreign policy, Clinton ordered U.S. military intervention in the Bosnian and Kosovo wars, eventually signing the Dayton Peace agreement. He also called for the expansion of NATO in Eastern Europe and many former Warsaw Pact members joined NATO during his presidency. Clinton's foreign policy in the Middle East saw him sign the Iraq Liberation Act which gave aid to groups against Saddam Hussein. He also participated in the Oslo I Accord and Camp David Summit to advance the Israeli–Palestinian peace process, and assisted the Northern Ireland peace process.\n\nClinton's second term was dominated by the Monica Lewinsky scandal, which began in 1996, when he had a sexual relationship with 22-year-old Monica Lewinsky, an intern at the White House. In January 1998, news of the affair made tabloid headlines. This scandal escalated throughout the year, culminating on December 19 when Clinton was impeached by the House of Representatives, becoming the second U.S. president—the first since Andrew Johnson—to be impeached. The two impeachment articles that the House passed were centered around him using the powers of the presidency to obstruct the investigation and lying under oath. In 1999, Clinton's impeachment trial began in the Senate. He was acquitted on both charges as the Senate failed to cast 67 votes against him, which was necessary to meet the two-thirds conviction threshold prescribed by Article I, section 3, clause 6 of the U.S. Constitution.\n\nClinton left office in 2001 with the joint-highest approval rating of any U.S. president in the modern era, alongside Franklin D. Roosevelt and Ronald Reagan. His presidency has been ranked among the upper tier in historical rankings of U.S. presidents. However, his personal conduct and allegations of sexual assault have made him the subject of substantial scrutiny. Since leaving office, Clinton has been involved in public speaking and humanitarian work. He created the Clinton Foundation to address international causes such as the prevention of HIV/AIDS and global warming. In 2009, he was named the United Nations Special Envoy to Haiti. After the 2010 Haiti earthquake, Clinton and George W. Bush formed the Clinton Bush Haiti Fund. He has remained active in Democratic Party politics, campaigning for his wife's 2008 and 2016 presidential campaigns.",

        "question": "What is some advice for planning an Alaskan vacation?",
        "evidence": "",
        "answer": "First, you need to determine what are your goals for visiting Alaska. Do you enjoy summer activities or winter activities? Do you want to see the Northern Lights or would you rather vacation under the Midnight Sun? Once you have decided when to go, you can build your itinerary around these desired activities. It's important to note that if you want to work within a budget, it's more expensive during the summer. Plane tickets, hotels, and car rentals will be pricey and oftentimes harder to reserve. On the other hand, it will be cheaper to visit Alaska in the winter, as you will have more hotel options available to you, but fewer flight options, and you will need to have winter driving experience if you rent a car.\n\nIn the summertime, you will get to experience the state in full bloom -- pun intended. Because Alaska gets more direct sunlight during this time of year, everything grows big and fast. The best months for a summertime visit are late May, June, and July. The further north you go, the more sunlight you will have, with 24 hours of full sun in Utqiagvik (formerly known as Barrow). There are plenty of places to go hiking, fishing, camping, and hunting. Don't forget to bring bug spray, as the mosquitoes are huge and plentiful; you'll also likely encounter \"no-see-ums\" which are tiny biting midges that can swarm you. In Anchorage, the biggest city, you can rent a bicycle to ride the hundreds of miles of trails within the municipality. Keep in mind that despite the extra sun exposure, you'll likely encounter cold and rainy weather, so bring a rain jacket.\n\nIn the wintertime, you will have the opportunity to see the Northern Lights. The further north you are, the chances are higher that you will see them. When it's very cold and clear out, and if you're away from city light pollution, you're almost guaranteed to see a beautiful display in the night sky. While you might not have much success camping or fishing, you can still do other activities like skiing and snowboarding at the world-famous Alyeska resort, ice skating on many public-use ponds and lakes, and perhaps catch the ceremonial start of the Iditarod dog race in February. Don't forget to bring lots of warm clothes and to layer up from head-to-toe. Average December temperatures across Alaska vary from a low of 27F in Juneau to -20F in Tok, but it isn't unusual for temperatures to drop much, much further.\n\nMany people don't realize that Alaska is a very, very big state. Don't try to cram too many activities into a short amount of time and give yourself plenty of time to travel to your intended destinations. There most reliable transportation is either a car or plane; there is not a well-developed rail system nor other public transport system. Some car rental company won't let you drive to certain areas because of inherent highway dangers, such as unpaved, gravel roads, isolation, and animal dangers. You'll encounter delays on roads in the summer due to road construction and delays in the winter due to accidents, ice, and blizzards.\n\nNo matter what time of year you go, there will be plenty to see and do in Alaska. Just remember to plan ahead, budget accordingly, dress appropriately for the weather, and build some flexibility into your itinerary to accommodate for delays or unexpected changes.",

        "question": "Does the authors' model outperform the previous state-of-arts on the SimpleQuestions dataset?",
        "answer": "Yes.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nIn particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% (Bordes et al., 2015) by 8.2% and 6.4% respectively.",

Madhavan, Irrfan Khan, Soha Ali Khan, Paresh Rawal and Kay Kay Menon. It deals with the aftermath of the 11 July 2006 Mumbai train bombings, where 209 people lost their lives and over 700 were injured. It won multiple Filmfare Awards.Rupali Joshi (Soha Ali Khan) is a successful reporter who is getting married in two months. Nikhil Agrawal (Madhavan) is an environmentally conscious executive who rides the train to work every day and is expecting his first child. Suresh (Kay Kay Menon) is a struggling computer tech who spends his time loafing at a local cafe and criticizing Muslims. Meanwhile, Sunil Kadam (Vijay Maurya) struggles with the corruption and inefficiency of the Mumbai police force and his boss, Tukaram Patil (Paresh Rawal), who is nearing retirement.On 11 July Nikhil and Suresh are in the second class compartment of a train when a bomb goes off in the first class compartment. The two survive, but Nikhil is too afraid to take the train again and is diagnosed with acute stress disorder. Suresh becomes obsessed with punishing the city's Muslims and is only stopped from antagonising them by Kadam and Patil on patrol. Kadam and Patil abuse a street vendor named Thomas (Irrfan Khan) who begins calling in fake bomb scares at malls to relieve his feelings. After an elderly man suffers a heart attack while the police are evacuating one mall, Thomas feels guilty and decides to stop.Rupali, who rushed to the scene of the bombings to cover the story, is devastated when she discovers that her fiancé died in the blasts. Her grief is augmented when the news channel she works for tries to exploit her story for ratings. Meanwhile, Suresh pursues a Muslim that he suspects of being a terrorist. However, after Patil stops him and lectures him on communal harmony, Suresh befriends the man.After Nikhil's wife goes into labour, he is forced to take the train to get to the hospital. Mumbai stops for two minutes while the city observes a moment of silence for those killed in the bombings. Patil finally retires from the police force and Kadam forgives him for his corrupt actions. Nikhil overcomes his fear of trains and Thomas gives a rose to the elderly man whose heart attack he caused.Filmfare Critics Award for Best Movie - WinnerFilmfare Best Screenplay Award - WinnerFilmfare Best Editing Award - WinnerNational Film Award for Best Special Effects for Govardhan (Tata Elxsi) - WinnerBest Feature Film at the New Generation Cinema Lyon Film Festival - WinnerBest Screenplay award at the 2009 Asia Pacific Screen Awards - NominationThe end titles are accompanied by the song \\Aye Dil Hain Mushkil\\\" (also known as \\\"Bombay Meri Jaan\\\") from the 1956 film C.I.D.",

Since its conclusion, the show has been lauded by critics as one of the greatest television series of all time. It had fair viewership in its first three seasons, but the fourth and fifth seasons saw a moderate rise in viewership when it was made available on Netflix just before the fourth season premiere. Viewership increased more drastically upon the premiere of the second half of the fifth season in 2013. By the time that the series finale aired, it was among the most-watched cable shows on American television. The show received numerous awards, including 16 Primetime Emmy Awards, eight Satellite Awards, two Golden Globe Awards, two Peabody Awards, two Critics' Choice Awards, and four Television Critics Association Awards. Cranston won the Primetime Emmy Award for Outstanding Lead Actor in a Drama Series four times, while Aaron Paul won the Primetime Emmy Award for Outstanding Supporting Actor in a Drama Series three times; Anna Gunn won the Primetime Emmy Award for Outstanding Supporting Actress in a Drama Series twice.

Get a job right away, a restaurant will be the easiest as they don’t do background checks so yes, lie on the application in this case\n4. Go to school, start at a jr college with a plan to transfer to a university, not a bs for profit school but an actual well know university\n5. Do not pick a major out of passion….pick a major to get you out of the hole you dug yourself into….anything business related like finance or tech related like data science is a great place to start\n6. Get on the honor roll, do whatever it takes, yes, you need to actually read the textbooks\n7. Stay on top of your mental health and recovery, seek therapy attend meetings do what you have to do to stay on the right path\n8. Avoid all drugs and alcohol to stay focused…especially during your 5 year probation and especially if you have a joint suspension \n9. Accelerate your studies, take 21 units if you can while maintaining straight A’s (this is possible)\n10.  Stay as busy as you can, boredom leads to trouble \n11. Apply to transfer to your local university, you can’t leave your town until you’re off probation anyways so might as well stay local\n12. When you get in, work even harder, stay on the honor roll and try to get in any honors programs you can\n13. Pay all your restitution and recovery in full\n14. Probation starts when you’re sentenced at the beginning of serving your time….so if you time this right you can go up for expungement at the same time you will be graduating, so be time conscious \n15. Assuming you are broke and you can’t afford $10 - $15 k for an expungement attorney….start looking into Californian penal code 1203.4. \n16. Go down to the courthouse…get the forms if you haven’t printed them already and ask questions\n17. Get all your case information gathered and fill out the forms\n18. Get your court date\n19. Collect letters of recommendation from any important person you know, business letterhead is nice to have but not everyone will be comfortable having their company vouch for you. Go to professors, bosses, family, “good” friends, mentors etc. These conversations may be difficult, especially if these people don’t know your past…but you have to do this\n20. Write a letter to the judge, short but powerful, something that would shed a tear\n21. On the day of your expungement hearing…dress your best\n22. Invite everyone who will come to support you at your hearing, the more support the more the judge believes you’re not a total POS and you just were a little lost at some point\n23. Be humble and respectful on that stand. Show grace and composure.\n24. There’s only about 6% of expungement requests that get granted so if the judge gives it to you….be grateful. You may not be able to help dropping to your knees and crying\n25. If you don’t get it, listen to what the judge says and try again \n26. Regardless of what happens just know that there is no such thing as luck, you got in this mess from making stupidly ridiculous decisions, and the only way to get out of it is by making extremely smart good decisions.\n27. Once you’re expunged….it takes about three months for your record to be expunged from both California and the FBI National database, so hang tight.\n28. Start applying for jobs, stay away from schools or anywhere that requires a Livescan. You can pass all background checks but those….and if you end up working for a defense contractor which you totally can….do not ever go for a role that requires a secret or top secret clearance \n29. If you’ve made it this far you've just gotten started, get your masters degree next, and keep going from there, get two or even a Doctorate, there is no limit where you will go \n30.

So we trained fifty models for each language and each architecture. Figure FIGREF23 visualises the means and standard deviations over the trained models. In addition, we visualise the average accuracy for the five best models for each language and architecture, as these are the models we use in the final ensemble prediction. Below we refer to these numbers only.\nThe results indicate that encoding the full context with an LSTM highly enhances the performance of the model, by 11.15% on average. This observation explains the high results we obtain also for Track 2.\nAdding the auxiliary objective of MSD prediction has a variable effect: for four languages (de, en, es, and sv) the effect is positive, while for the rest it is negative. We consider this to be an issue of insufficient data for the training of the auxiliary component in the low resource setting we are working with.\nWe indeed see results improving drastically with the introduction of multilingual training, with multilingual results being 7.96% higher than monolingual ones on average.\nWe studied the five best models for each language as emerging from the multilingual training (listed in Table TABREF27 ) and found no strong linguistic patterns. The en–sv pairing seems to yield good models for these languages, which could be explained in terms of their common language family and similar morphology. The other natural pairings, however, fr–es, and de–sv, are not so frequent among the best models for these pairs of languages.\nFinally, monolingual finetuning improves accuracy across the board, as one would expect, by 2.72% on average.\nThe final observation to be made based on this breakdown of results is that the multi-tasking approach paired with multilingual training and subsequent monolingual finetuning outperforms the other architectures for five out of seven languages: de, en, fr, ru and sv. For the other two languages in the dataset, es and fi, the difference between this approach and the approach that emerged as best for them is less than 1%. The overall improvement of the multilingual multi-tasking approach over the baseline is 18.30%.\nSo we trained fifty models for each language and each architecture.",

In addition, our annotations of non-standardized orthographic transcriptions could be extremely useful in the study of historical language and orthography change as a language moves from predominantly oral to being written in a standardized orthography, as well as in building spelling normalization and correction systems.

        "evidence": "Language modelling in its inception had one-hot vector encoding of words. However, it captures only alphabetic ordering but not the word semantic similarity. Vector space models helps to learn word representations in a lower dimensional space and also captures semantic similarity. Learning word embedding aids in natural language processing tasks such as question answering and reasoning BIBREF0, stance detection BIBREF1, claim verification BIBREF2.\nRecent models BIBREF3, BIBREF4 work on the basis that words with similar context share semantic similarity. BIBREF4 proposes a neural probabilistic model which models the target word probability conditioned on the previous words using a recurrent neural network. Word2Vec models BIBREF3 such as continuous bag-of-words (CBOW) predict the target word given the context, and skip-gram model works in reverse of predicting the context given the target word. While, GloVe embeddings were based on a Global matrix factorization on local contexts BIBREF5. However, the aforementioned models do not handle words with multiple meanings (polysemies).\nBIBREF6 proposes a neural network approach considering both local and global contexts in learning word embeddings (point estimates). Their multiple prototype model handles polysemous words by providing apriori heuristics about word senses in the dataset. BIBREF7 proposes an alternative to handle polysemous words by a modified skip-gram model and EM algorithm. BIBREF8 presents a non-parametric based alternative to handle polysemies. However, these approaches fail to consider entailment relations among the words. BIBREF9 learn a Gaussian distribution per word using the expected likelihood kernel. However, for polysemous words, this may lead to word distributions with larger variances as it may have to cover various senses.\nBIBREF10 proposes multimodal word distribution approach. It captures polysemy. However, the energy based objective function fails to consider asymmetry and hence entailment. Textual entailment recognition is necessary to capture lexical inference relations such as causality (for example, mosquito $\\rightarrow $ malaria), hypernymy (for example, dog $\\models $ animal) etc.\nIn this paper, we propose to obtain multi-sense word embedding distributions by using a variant of max margin objective based on the asymmetric KL divergence energy function to capture textual entailment. Multi-sense distributions are advantageous in capturing polysemous nature of words and in reducing the uncertainty per word by distributing it across senses. However, computing KL divergence between mixtures of Gaussians is intractable, and we use a KL divergence approximation based on stricter upper and lower bounds. While capturing textual entailment (asymmetry), we have also not compromised on capturing symmetrical similarity between words (for example, funny and hilarious) which will be elucidated in Section $3.1$. We also show the effectiveness of the proposed approach on the benchmark word similarity and entailment datasets in the experimental section.\nIn this paper, we propose to obtain multi-sense word embedding distributions by using a variant of max margin objective based on the asymmetric KL divergence energy function to capture textual entailment.",

        "answer": "The target domain here simply refers to that part of the world that is being described by the variables and their interaction. I will make this explicit.",
        "evidence": "Assume that we have an ML-model which implements the overall function h : R(I) → R(Y ), where I consists of all the input variables and Y is the single output variable. As mentioned, we also assume knowledge of a causal model M of the target domain (i.e., that part of the world which h is a model of). A first requirement is that such a causal model is consistent with the ML-model, meaning that they at least agree on how to classify all observations. A second requirement that is helpful given the conceptual nature of our analysis is that the endogenous variables I suffice to obtain deterministic causal knowledge of the target domain. Technically this means that there are only two kinds of endogenous variables: those which are determined directly by the unobserved exogenous variables, and those which are determined entirely by members of I. In future work both requirements can be loosened by adding probabilities to each. For the first, we can demand that both models are likely to agree on observations. For the second, we can add new exogenous variables and a probability distribution over them, which give us probabilistic causal models. These allow for probabilistic generalizations of all the definitions here presented.\neither has a unique single exogenous parent U i ∈ U or no exogenous parents, and for all i ∈ R(I), y ∈ R(Y ):\nAs knowledge of the causal model is hard to come by many approaches to action-guiding explanations ignore it entirely and assume that the input variables are causally independent.\nDefinition 4 A causal model M that agrees with h satisfies Independence if for each I a , I b ∈ I, I a is not a parent of I b .\nObviously Independence rarely holds, and thus any account of action-guiding explanation that depends on it is limited. Although this limitation is recognized, this paper offers several results that formally characterize how extreme this limitation is. Simply put, under Independence a variety of very different causal notions become indistinguishable from each other. This holds for notions of sufficient explanation, counterfactual explanations, and various notions of actual causation.\nBecause of this limitation, work on action-guiding explanations in XAI has failed to take up the most relevant lesson that the literature on causation has to offer, namely that to give a causal explanation of an outcome is to give actual causes of that outcome. An additional reason for this oversight is that the precise relation between explanation and prediction has been the subject of much debate in the history of philosophy of science.\nPrediction in its most natural application is a forward-looking notion, meaning one predicts an event before it takes place. Explanation on the other hand is a backward-looking notion, meaning that one explains an event after it has happened. Yet as many papers on XAI clearly illustrate, explanations about past events are often required precisely to inform predictions about future events. Therefore a suitable notion of causal explanation, and thus also of actual causation, needs to specify how it relates to predictions. Given the tumultuous history that this relation has in the philosophy literature, it has been duly neglected in the philosophical work on causation, thereby obscuring the importance of causation for the practical goals that XAI is concerned with. forms a notable exception!) 2 This paper corrects this by developing an account of causal explanation that shows both how it is connected to actual causation and how it can lead to action-guiding predictions.\nSimply put, the goal of this paper is to upgrade the formalization of Woodward's influential philosophical account of causal explanation described below with the most recent insights from the causation literature, whilst also keeping track of the action-guiding demands that are prevalent in XAI.\nPut differently, my idea is that one ought to be able to associate with any successful explanation a hypothetical or counterfactual experiment that shows us that and how manipulation of the factors mentioned in the explanation (the explanans, as philosophers call it) would be a way of manipulating or altering the phenomenon explained (the explanandum). Put in still another way, an explanation ought to be such that it can be used to answer what I call a what-if-things-had-been-different question: the explanation must enable us to see what sort of difference it would have made for the explanandum if the factors cited in the explanans had been different in various possible ways.\nA crucial novel element of my account is the addition that a successful explanation must also be explicit about those factors that may not be manipulated for the explanation to hold, i.e., it must state which variables are to be safeguarded from interventions. Importantly, this is distinct from stating which variables must be held fixed at their actual values, for to hold variables fixed in fact means to intervene on them.\nThe following example (modified from) is helpful for illustrating the various purposes that explanations can serve.\nExample 1 Consider a system for loan applications that is captured by a causal model such that\nwhere Y is a binary variable representing whether the loan is granted, X 1 is the applicant's income, and X 2 is the applicant's savings. Further, assume that the applicant's savings are determined by their initial deposit X 3 and their income in the following manner: X 2 = 3/10 • X 1 + X 3 . It is also the case that people with high savings take out a safety deposit box (X 4 ) at the bank: X 4 = X 2 > 1, 000, 000.\nStandard predictions in ML take place on the first rung of Pearl's causal ladder, namely that of observations. For example, an ML-model might pick up on the fact that all observed loan applicants who have a safety deposit box (X 4 = 1) also get a loan (Y = 1), and thus could predict that an applicant who has a safety deposit box will get a loan, i.e., it might learn a function so that h(x 1 , x 2 , x 3 , 1) = 1 for all values x 1 , x 2 , x 3 . In terms of the causal model, it is indeed the case that refer to as an anchor, which they interpret as a sufficient explanation of the outcome. Yet clearly such observational explanations are not a good guide towards action, for it would be absurd to recommend to someone to take out a safety deposit box so that their loan application is approved. This point can be brought out by making use of the second rung of the ladder, namely that of interventions: an applicant who takes out a safety deposit box as the result of being advised to do so will not necessarily get a loan:\nIn the same manner, interventions can be used to offer advice that is a good guide towards action, for example by telling an applicant that if they manage to obtain savings of 45, 001 then they are guaranteed to get a loan:\nAs mentioned, we also assume knowledge of a causal model M of the target domain (i.e., that part of the world which\nh is a model of).",

These three items are considered by the science only in relation to the increase or diminution of wealth, and not in reference to their processes of execution. Say's definition has prevailed up to our time, saved by substituting the word \"wealth\" for \"goods and services\" meaning that wealth may include non-material objects as well. One hundred and thirty years later, Lionel Robbins noticed that this definition no longer sufficed, because many economists were making theoretical and philosophical inroads in other areas of human activity. In his Essay on the Nature and Significance of Economic Science, he proposed a definition of economics as a study of a particular aspect of human behaviour, the one that falls under the influence of scarcity, which forces people to choose, allocate scarce resources to competing ends, and economize (seeking the greatest welfare while avoiding the wasting of scarce resources). For Robbins, the insufficiency was solved, and his definition allows us to proclaim, with an easy conscience, education economics, safety and security economics, health economics, war economics, and of course, production, distribution and consumption economics as valid subjects of the economic science.\" Citing Robbins: \"Economics is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses\". After discussing it for decades, Robbins' definition became widely accepted by mainstream economists, and it has opened way into current textbooks. Although far from unanimous, most mainstream economists would accept some version of Robbins' definition, even though many have raised serious objections to the scope and method of economics, emanating from that definition. Due to the lack of strong consensus, and that production, distribution and consumption of goods and services is the prime area of study of economics, the old definition still stands in many quarters.",

In May 1993 he became the first Venezuelan president to be forced out of office by the Supreme Court on charges for the embezzlement of 250 million bolívars (roughly 2.7 million US dollars) belonging to a presidential discretionary fund, whose money was used to support the electoral process in Nicaragua and hire bodyguards for President Violeta Chamorro.",

Hence, automatic metrics that compare the generated text to one or more reference texts are routinely used to compare models BIBREF7 . For table-to-text generation, automatic evaluation has largely relied on BLEU BIBREF8 and ROUGE BIBREF9 . The underlying assumption behind these metrics is that the reference text is gold-standard, i.e., it is the ideal target text that a system should generate. In practice, however, when datasets are collected automatically and heuristically, the reference texts are often not ideal. Figure FIGREF2 shows an example from the WikiBio dataset BIBREF0 . Here the reference contains extra information which no system can be expected to produce given only the associated table. We call such reference texts divergent from the table.\nWe show that existing automatic metrics, including BLEU, correlate poorly with human judgments when the evaluation sets contain divergent references (§ SECREF36 ). For many table-to-text generation tasks, the tables themselves are in a pseudo-natural language format (e.g., WikiBio, WebNLG BIBREF6 , and E2E-NLG BIBREF10 ). In such cases we propose to compare the generated text to the underlying table as well to improve evaluation. We develop a new metric, PARENT (Precision And Recall of Entailed N-grams from the Table) (§ SECREF3 ). When computing precision, PARENT effectively uses a union of the reference and the table, to reward correct information missing from the reference. When computing recall, it uses an intersection of the reference and the table, to ignore extra incorrect information in the reference. The union and intersection are computed with the help of an entailment model to decide if a text n-gram is entailed by the table. We show that this method is more effective than using the table as an additional reference. Our main contributions are:\nWe develop a new metric, PARENT (Precision And Recall of Entailed Ngrams from the Table) (§3).",

        "question": "Whose integrated functions are stronger? FBFans dataset or CreateDebate dataset?",
        "answer": "The FBFans dataset.",
        "evidence": "We tested the proposed UTCNN on two different datasets: FBFans and CreateDebate. FBFans is a privately-owned, single-topic, Chinese, unbalanced, social media dataset, and CreateDebate is a public, multiple-topic, English, balanced, forum dataset. Results using these two datasets show the applicability and superiority for different topics, languages, data distributions, and platforms.\nThe FBFans dataset contains data from anti-nuclear-power Chinese Facebook fan groups from September 2013 to August 2014, including posts and their author and liker IDs. There are a total of 2,496 authors, 505,137 likers, 33,686 commenters, and 505,412 unique users. Two annotators were asked to take into account only the post content to label the stance of the posts in the whole dataset as supportive, neutral, or unsupportive (hereafter denoted as Sup, Neu, and Uns). Sup/Uns posts were those in support of or against anti-reconstruction; Neu posts were those evincing a neutral standpoint on the topic, or were irrelevant. Raw agreement between annotators is 0.91, indicating high agreement. Specifically, Cohen’s Kappa for Neu and not Neu labeling is 0.58 (moderate), and for Sup or Uns labeling is 0.84 (almost perfect). Posts with inconsistent labels were filtered out, and the development and testing sets were randomly selected from what was left. Posts in the development and testing sets involved at least one user who appeared in the training set. The number of posts for each stance is shown on the left-hand side of Table TABREF12 . About twenty percent of the posts were labeled with a stance, and the number of supportive (Sup) posts was much larger than that of the unsupportive (Uns) ones: this is thus highly skewed data, which complicates stance classification. On average, 161.1 users were involved in one post. The maximum was 23,297 and the minimum was one (the author). For comments, on average there were 3 comments per post. The maximum was 1,092 and the minimum was zero.\nTo test whether the assumption of this paper – posts attract users who hold the same stance to like them – is reliable, we examine the likes from authors of different stances. Posts in FBFans dataset are used for this analysis. We calculate the like statistics of each distinct author from these 32,595 posts. As the numbers of authors in the Sup, Neu and Uns stances are largely imbalanced, these numbers are normalized by the number of users of each stance. Table TABREF13 shows the results. Posts with stances (i.e., not neutral) attract users of the same stance. Neutral posts also attract both supportive and neutral users, like what we observe in supportive posts, but just the neutral posts can attract even more neutral likers. These results do suggest that users prefer posts of the same stance, or at least posts of no obvious stance which might cause annoyance when reading, and hence support the user modeling in our approach.\nThe CreateDebate dataset was collected from an English online debate forum discussing four topics: abortion (ABO), gay rights (GAY), Obama (OBA), and marijuana (MAR). The posts are annotated as for (F) and against (A). Replies to posts in this dataset are also labeled with stance and hence use the same data format as posts. The labeling results are shown in the right-hand side of Table TABREF12 . We observe that the dataset is more balanced than the FBFans dataset. In addition, there are 977 unique users in the dataset. To compare with Hasan and Ng's work, we conducted five-fold cross-validation and present the annotation results as the average number of all folds BIBREF9 , BIBREF5 .\nThe FBFans dataset has more integrated functions than the CreateDebate dataset; thus our model can utilize all linguistic and extra-linguistic features. For the CreateDebate dataset, on the other hand, the like and comment features are not available (as there is a stance label for each reply, replies are evaluated as posts as other previous work) but we still implemented our model using the content, author, and topic information.\nThe FBFans dataset has more integrated functions than the CreateDebate dataset; thus our model can utilize all linguistic and extra-linguistic features.",

        "answer": "A country's success in a given sport at the international level will depend on a number of factors other than population alone. While a country's population is a good identifier for the total selection pool for high performing athletes to come from, it is one of many factors. A country's founding history, climate zone, and GDP are other notable factors in sport performance. \n\nA nations history plays factor as many sports are baked in centuries of tradition. For example, Cricket, which is believed to have originated in England is most popular in countries that were originally British Colonies. Long traditions such as this set specific sports into the culture of a nation, increasing the percentage of the athlete pool that it can pull from and can increase the level at which that nation is competitive. \n\nClimate zone can also influence the competitiveness of a country in given sports. Norway, fore example, earned the most olympic medals of any country in the 2022 olympic games with a total of 37 medals. In the summer games of 2020 (held in 2021), Norway ranked 20th overall with just 8 medals. Norways Climate and Topography have led winter sports to be extremely popular, and Norway has over time developed elite programs in cross country/nordic skiing, speed skating, curling, biathlon, and ski jumping. \n\nA nations wealth will also influence performance in sport at the international level. This occurs predominantly for two reasons. First is that more money enables larger budgets on equipment, coaching, player development, participation in international circuits, data insights, medical staff etc. that over time create a performance separation from those who can not afford these things. Second is access to sports, many sports are quite expensive some examples include snow sports, gymnastics, swimming, hockey, and polo.

        "evidence": "Anaplasmosis is a tick-borne disease affecting ruminants, dogs, and horses, and is caused by Anaplasma bacteria. Anaplasmosis is an infectious but not contagious disease. Anaplasmosis can be transmitted through mechanical and biological vector processes. Anaplasmosis can also be referred to as \"yellow bag\" or \"yellow fever\" because the infected animal can develop a jaundiced look. Other signs of infection include weight loss, diarrhea, paleness of the skin, aggressive behavior, and high fever.\n\nMany different tick species can carry the bacteria that cause anaplasmosis. The two major bacterial pathogens are Anaplasma marginale and Anaplasma phagocytophilum. These microorganisms are Gram-negative, and infect red blood cells. Once the host is infected with anaplasmosis, the immune system will try to fight off and kill the infected red blood cells, but will also kill healthy red blood cells. The Anaplasma sparouinense species is responsible for a rare zoonosis, the Sparouine anaplasmosis, detected only in French Guiana, South America. This disease was described from a clandestine gold miner working deep in rainforest. Infection of his red blood cells led to a severe deterioration of his health and required his hospitalization. Molecular typing showed that Anaplasma sparouinense is distinct to all known species and more genetically related to recently described Anaplasma species causing infections in rainforest wild fauna of Brazil.\n\nWhile there are no current live or inactivated vaccines effective for all strains of A. marginale approved by the USDA for anaplasmosis, there are other means of prevention. Tick and fly control for herds of ruminants can be effective but also labor intensive. Chemical methods can also be used, including sanitizing surgical equipment after each use. Tetracycline drugs are the most common treatment for anaplasmosis, and can provide the animal with immunity for a period of time. The disease is more common in the South and West parts of the United States, but is no longer considered a major problem since the use of tetracycline drugs.",

However, we cannot apply BERT to language generation tasks as is because its model structure is not suitable for language generation. Several pre-trained seq-to-seq models for language generation BIBREF1, BIBREF2 based on an encoder-decoder Transformer model, which is a standard model for language generation, have recently been proposed. These models have achieved blackstate-of-the-art results in various language generation tasks, including abstractive summarization.\nHowever, when generating a summary, it is essential to correctly predict which part of the source text should be included in the summary. Some previous studies without pre-training have examined combining extractive summarization with abstractive summarization BIBREF3, BIBREF4. Although pre-trained seq-to-seq models have achieved higher accuracy compared to previous models, it is not clear whether modeling “Which part of the source text is important?” can be learned through pre-training.\nblackThe purpose of this study is to clarify the blackeffectiveness of combining saliency models that identify the important part of the source text with a pre-trained seq-to-seq model in the abstractive summarization task.

        "question": "Was the other feature used for ranking documents?",
        "answer": "No, it wasn't.",
        "evidence": "In information retrieval (IR), queries and documents are typically represented by term vectors where each term is a content word and weighted by tf-idf, i.e. the product of the term frequency and the inverse document frequency, or other weighting schemes BIBREF0 . The similarity of a query and a document is then determined as a dot product or cosine similarity. Although this works reasonably, the traditional IR scheme often fails to find relevant documents when synonymous or polysemous words are used in a dataset, e.g. a document including only “neoplasm\" cannot be found when the word “cancer\" is used in a query. One solution of this problem is to use query expansion BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 or dictionaries, but these alternatives still depend on the same philosophy, i.e. queries and documents should share exactly the same words.\nWhile the term vector model computes similarities in a sparse and high-dimensional space, the semantic analysis methods such as latent semantic analysis (LSA) BIBREF5 , BIBREF6 and latent Dirichlet allocation (LDA) BIBREF7 learn dense vector representations in a low-dimensional space. These methods choose a vector embedding for each term and estimate a similarity between terms by taking an inner product of their corresponding embeddings BIBREF8 . Since the similarity is calculated in a latent (semantic) space based on context, the semantic analysis approaches do not require having common words between a query and documents. However, it has been shown that LSA and LDA methods do not produce superior results in various IR tasks BIBREF9 , BIBREF10 , BIBREF11 and the classic ranking method, BM25 BIBREF12 , usually outperforms those methods in document ranking BIBREF13 , BIBREF14 .\nNeural word embedding BIBREF15 , BIBREF16 is similar to the semantic analysis methods described above. It learns low-dimensional word vectors from text, but while LSA and LDA utilize co-occurrences of words, neural word embedding learns word vectors to predict context words BIBREF10 . Moreover, training of semantic vectors is derived from neural networks. Both co-occurrence and neural word embedding approaches have been used for lexical semantic tasks such as semantic relatedness (e.g. king and queen), synonym detection (e.g. cancer and carcinoma) and concept categorization (e.g. banana and pineapple belong to fruits) BIBREF10 , BIBREF17 . But, Baroni et al. Baroni2014 showed that neural word embedding approaches generally performed better on such tasks with less effort required for parameter optimization. The neural word embedding models have also gained popularity in recent years due to their high performance in NLP tasks BIBREF18 .\nHere we present a query-document similarity measure using a neural word embedding approach. This work is particularly motivated by the Word Mover's Distance BIBREF19 . Unlike the common similarity measure taking query/document centroids of word embeddings, the proposed method evaluates a distance between individual words from a query and a document. Our first experiment was performed on the TREC 2006 and 2007 Genomics benchmark sets BIBREF20 , BIBREF21 , and the experimental results showed that our approach was better than BM25 ranking. This was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.\nIn general, conventional ranking models (e.g. BM25) rely on a manually designed ranking function and require heuristic optimization for parameters BIBREF22 , BIBREF23 . In the age of information explosion, this one-size-fits-all solution is no longer adequate. For instance, it is well known that links to a web page are an important source of information in web document search BIBREF24 , hence using the link information as well as the relevance between a query and a document is crucial for better ranking. In this regard, learning to rank BIBREF22 has drawn much attention as a scheme to learn how to combine diverse features. Given feature vectors of documents and their relevance levels, a learning to rank approach learns an optimal way of weighting and combining multiple features.\nWe argue that the single scores (or features) produced by BM25 and our proposed semantic measure complement each other, thus merging these two has a synergistic effect. To confirm this, we measured the impact on document ranking by combining BM25 and semantic scores using the learning to rank approach, LamdaMART BIBREF25 , BIBREF26 . Trained on PubMed user queries and their click-through data, we evaluated the search performance based on the most highly ranked 20 documents. As a result, we found that using our semantic measure further improved the performance of BM25.\nTaken together, we make the following important contributions in this work. First, to the best of our knowledge, this work represents the first investigation of query-document similarity for information retrieval using the recently proposed Word Mover's Distance. Second, we modify the original Word Mover's Distance algorithm so that it is computationally less expensive and thus more practical and scalable for real-world search scenarios (e.g. biomedical literature search). Third, we measure the actual impact of neural word embeddings in PubMed by utilizing user queries and relevance information derived from click-through data. Finally, on TREC and PubMed datasets, our proposed method achieves stronger performance than BM25.\nThis was solely based on matching queries and documents by the semantic measure and no other feature was used for ranking documents.",

In the context of question answering, question classification allows automated systems to intelligently target their inference systems to domain-specific solvers capable of addressing specific kinds of questions and problem solving methods with high confidence and answer accuracy BIBREF0 , BIBREF1 .\nTo date, question classification has primarily been studied in the context of open-domain TREC questions BIBREF2 , with smaller recent datasets available in the biomedical BIBREF3 , BIBREF4 and education BIBREF5 domains. The open-domain TREC question corpus is a set of 5,952 short factoid questions paired with a taxonomy developed by Li and Roth BIBREF6 that includes 6 coarse answer types (such as entities, locations, and numbers), and 50 fine-grained types (e.g. specific kinds of entities, such as animals or vehicles). While a wide variety of syntactic, semantic, and other features and classification methods have been applied to this task, culminating in near-perfect classification performance BIBREF7 , recent work has demonstrated that QC methods developed on TREC questions generally fail to transfer to datasets with more complex questions such as those in the biomedical domain BIBREF3 , likely due in part to the simplicity and syntactic regularity of the questions, and the ability for simpler term-frequency models to achieve near-ceiling performance BIBREF8 . In this work we explore question classification in the context of multiple choice science exams. Standardized science exams have been proposed as a challenge task for question answering BIBREF9 , as most questions contain a variety of challenging inference problems BIBREF10 , BIBREF11 , require detailed scientific and common-sense knowledge to answer and explain the reasoning behind those answers BIBREF12 , and questions are often embedded in complex examples or other distractors. Question classification taxonomies and annotation are difficult and expensive to generate, and because of the unavailability of this data, to date most models for science questions use one or a small number of generic solvers that perform little or no question decomposition BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 . Our long-term interest is in developing methods that intelligently target their inferences to generate both correct answers and compelling human-readable explanations for the reasoning behind those answers. The lack of targeted solving – using the same methods for inferring answers to spatial questions about planetary motion, chemical questions about photosynthesis, and electrical questions about circuit continuity – is a substantial barrier to increasing performance (see Figure FIGREF1 ).\nTo address this need for developing methods of targetted inference, this work makes the following contributions:\nIn this work we explore question classification in the context of multiple choice science exams.",

The movement of electric charges is an electric current and produces a magnetic field. In most applications, a force acts on a charge with a magnitude given by Coulomb's law. Electric potential is typically measured in volts.\nElectricity is at the heart of many modern technologies, being used for:\nElectric power where electric current is used to energise equipment;\nElectronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.\nElectrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the 17th and 18th centuries. The theory of electromagnetism was developed in the 19th century, and by the end of that century electricity was being put to industrial and residential use by electrical engineers. The rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution.

Given a sentence as an input, contextual embedding for the words are returned. The BERT model was designed so it can be fine tuned for 11 different tasks BIBREF1, including question answering tasks. For a question answering task, question and paragraph (context) are given as an input. A BERT standard is that question text and paragraph text are separated by a separator [Sep]. BERT question-answering fine tuning involves adding softmax layer. Softmax layer takes contextual word embeddings from BERT as input and learns to identity answer span present in the paragraph (context). This process is represented in Figure FIGREF4.\nBERT was originally trained to perform tasks such as language model creation using masked words and next-sentence-prediction. In other words BERT weights are learned such that context is used in building the representation of the word, not just as a loss function to help learn a context-independent representation. For detailed understanding of BERT Architecture, please refer to the original BERT paper BIBREF1.\nA ‘word embedding’ is a learned representation. It is represented in the form of vector where words that have the same meaning have a similar vector representation. Consider a word embedding model 'word2vec' BIBREF6 trained on a corpus. Word embeddings generated from the model are context independent that is, word embeddings are returned regardless of where the words appear in a sentence and regardless of e.g. the sentiment of the sentence.

        "answer": "On both ZP prediction and translation.",
        "evidence": "Zero anaphora is a discourse phenomenon, where pronouns can be omitted when they are pragmatically or grammatically inferable from intra- and inter-sentential context BIBREF0 . However, translating such implicit information (i.e. zero pronoun, ZP) poses various difficulties for machine translation (MT) in terms of completeness and correctness. Although neural models are getting better at learning representations, it is still difficult to implicitly learn complex ZPs in a general model. Actually, ZP prediction and translation need to not only understand the semantics or intentions of a single sentence, but also utilize its discourse-level context.\nTwo technological advances in the field of ZP and MT, have seen vast progress over the last decades, but they have been developed very much in isolation. Early studies BIBREF1 , BIBREF2 , BIBREF3 fed MT systems with the results of ZP prediction models, which are trained on a small-scale and non-homologous data compared to MT models. To narrow the data-level gap, Wang:2016:NAACL proposed an automatic method to annotate ZPs by utilizing the parallel corpus of MT. The homologous data for both ZP prediction and translation leads to significant improvements on translation performances for both statistical MT BIBREF4 and neural MT models BIBREF5 . However, such approaches still require external ZP prediction models, which have a low accuracy of 66%. The numerous errors of ZP prediction errors will be propagated to translation models, which leads to new translation problems. In addition, relying on external ZP prediction models in decoding makes these approaches unwieldy in practice, due to introducing more computation cost and pipeline complexity.\nIn this work, we try to further bridge the model-level gap by jointly modeling ZP prediction and translation. Joint learning has proven highly effective on alleviating the error propagation problem, such as joint parsing and translation BIBREF6 , as well as joint tokenization and translation BIBREF7 . Similarly, we expect that ZP prediction and translation could interact with each other: prediction offers more ZP information beyond 1-best result to translation and translation helps prediction resolve ambiguity. Specifically, we first cast ZP prediction as a sequence labeling task with a neural model, which is trained jointly with a standard neural machine translation (NMT) model in an end-to-end manner. We leverage the auto-annotated ZPs to supervise the learning of ZP prediction component, which releases the reliance on external ZP knowledge in decoding phase.\nIn addition, previous studies revealed that discourse-level information can better tackle ZP resolution, because around 23% of ZPs appear two or more sentences away from their antecedents BIBREF8 , BIBREF9 . Inspired by these findings, we exploit inter-sentential context to further improve ZP prediction and thus translation. Concretely, we employ hierarchical neural networks BIBREF10 , BIBREF11 to summarize the context of previous sentences in a text, which is integrated to the joint model for ZP prediction.\nWe validate the proposed approach on the widely-used data for ZP translation BIBREF5 , which consist of 2.15M Chinese–English sentence pairs. Experimental results show that the joint model indeed improves performances on both ZP prediction and translation. Incorporating discourse-level context further improves performances, and outperforms ther external ZP prediction model BIBREF5 by +2.29 BLEU points in translation and +11% in prediction accuracy. Experimental results on a further Japanese–English translation task show that our model consistently outperforms both the baseline and the external ZP prediction model, demonstrating the universality of the proposed approach.\nThe key contributions of this paper are:\nExperimental results show that the joint model indeed improves performances on both ZP prediction and translation. Incorporating discourse-level context further improves performances, and outperforms ther external ZP prediction model by +2.29 BLEU points in translation and +11% in prediction accuracy.",

        "evidence": "Equations are an important part of scientific articles, but many existing machine learning methods do not easily handle them. They are challenging to work with because each is unique or nearly unique; most equations occur only once. An automatic understanding of equations, however, would significantly benefit methods for analyzing scientific literature. Useful representations of equations can help draw connections between articles, improve retrieval of scientific texts, and help create tools for exploring and navigating scientific literature.\nIn this paper we propose equation embeddings (EqEmb), an unsupervised approach for learning distributed representations of equations. The idea is to treat the equation as a \"singleton word,\" one that appears once but that appears in the context of other words. The surrounding text of the equation—and in particular, the distributed representations of that text—provides the data we need to develop a useful representation of the equation.\nFigure FIGREF1 illustrates our approach. On the left is an article snippet BIBREF0 . Highlighted in orange is an equation; in this example it represents a neural network layer. We note that this particular equation (in this form and with this notation) only occurs once in the collection of articles (from arXiv). The representations of the surrounding text, however, provide a meaningful context for the equation. Those words allow us to learn its embedding, specifically as a \"word\" which appears in the context of its surroundings. The resulting representation, when compared to other equations' representations and word representations, helps find both related equations and related words. These are illustrated on the right.\nEqEmbs build on exponential family embeddings BIBREF1 to include equations as singleton observations and to model equation elements such as variables, symbols and operators. Exponential family embeddings, like all embedding methods, define a context of each word. In our initial EqEmb, the context for the words is a small window, such as four or eight words, but the context of an equation is a larger window, such as sixteen words. Using these two types of contexts together finds meaningful representations of words and equations. In the next EqEmb, which builds on the first, we consider equations to be sentences consisting of equation units, i.e., variables, symbols, and operators. Equation units help model equations across two types of context—over the surrounding units and over the surrounding words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML). We found that EqEmbs provide more efficient modeling than existing word embedding methods. We further carried out an exploratory analysis of a large set of INLINEFORM0 87k equations. We found that EqEmbs provide better models when compared to existing word embedding approaches. EqEmbs also provide coherent semantic representations of equations and can capture semantic similarity to other equations and to words.\nWe studied EqEmbs on four collections of scientific articles from the arXiv, covering four computer science domains: natural language processing (NLP), information retrieval (IR), artificial intelligence (AI) and machine learning (ML).",

Suppose that events $x_1$ are $x_2$ are in the discourse relation of Cause (i.e., $x_1$ causes $x_2$). If the seed lexicon suggests $x_2$ is positive, $x_1$ is also likely to be positive because it triggers the positive emotion. The fact that $x_2$ is known to be negative indicates the negative polarity of $x_1$. Similarly, if $x_1$ and $x_2$ are in the discourse relation of Concession (i.e., $x_2$ in spite of $x_1$), the reverse of $x_2$'s polarity can be propagated to $x_1$. Even if $x_2$'s polarity is not known in advance, we can exploit the tendency of $x_1$ and $x_2$ to be of the same polarity (for Cause) or of the reverse polarity (for Concession) although the heuristic is not exempt from counterexamples. We transform this idea into objective functions and train neural network models that predict the polarity of a given event.\nThe seed lexicon consists of positive and negative predicates. If the predicate of an extracted event is in the seed lexicon and does not involve complex phenomena like negation, we assign the corresponding polarity score ($+1$ for positive events and $-1$ for negative events) to the event.

        "question": "Based on the following passage where did plums, apricots and peaches originate?",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

        "evidence": "* Equal contribution. Listing order is random.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma. More concretely, consider the English sentence: The bulls are running in Pamplona. A lemmatizer will seek to map each word to a form you may find in a dictionary—for instance, mapping running to run. This linguistic normalization is important in several downstream NLP applications, especially for highly inflected languages. Lemmatization has previously been shown to improve recall for information retrieval BIBREF0 , BIBREF1 , to aid machine translation BIBREF2 , BIBREF3 and is a core part of modern parsing systems BIBREF4 , BIBREF5 .\nHowever, the task is quite nuanced as the proper choice of the lemma is context dependent. For instance, in the sentence A running of the bulls took place in Pamplona, the word running is its own lemma, since, here, running is a noun rather than an inflected verb. Several counter-examples exist to this trend, as discussed in depth in haspelmath2013understanding. Thus, a good lemmatizer must make use of some representation of each word's sentential context. The research question in this work is, then, how do we design a lemmatization model that best extracts the morpho-syntax from the sentential context?\nRecent work BIBREF7 has presented a system that directly summarizes the sentential context using a recurrent neural network to decide how to lemmatize. As N18-1126's system currently achieves state-of-the-art results, it must implicitly learn a contextual representation that encodes the necessary morpho-syntax, as such knowledge is requisite for the task. We contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize. Indeed, to this end, we introduce a joint model for the introduction of morphology into a neural lemmatizer. A key feature of our model is its simplicity: Our contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model. However, despite the model's simplicity, it still achieves a significant improvement over the state of the art on our target task: lemmatization.\nExperimentally, our contributions are threefold. First, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora BIBREF8 . Second, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization. Finally, we provide a detailed error analysis indicating when and why morphological analysis helps lemmatization. We offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.\nOur system and pre-trained models on all languages in the latest version of the UD corpora are released at https://sigmorphon.github.io/sharedtasks/2019/task2/.\nOur contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model.",

        "evidence": "[0]leftmargin=* [0]leftmargin=*\nAutomatic systems have had a significant and beneficial impact on all walks of human life. So much so that it is easy to overlook their potential to benefit society by promoting equity, diversity, and fairness. For example, machines do not take bribes to do their jobs, they can determine eligibility for a loan without being influenced by the color of the applicant's skin, and they can provide access to information and services without discrimination based on gender or sexual orientation. Nonetheless, as machine learning systems become more human-like in their predictions, they can also perpetuate human biases. Some learned biases may be beneficial for the downstream application (e.g., learning that humans often use some insect names, such as spider or cockroach, to refer to unpleasant situations). Other biases can be inappropriate and result in negative experiences for some groups of people. Examples include, loan eligibility and crime recidivism prediction systems that negatively assess people belonging to a certain pin/zip code (which may disproportionately impact people of a certain race) BIBREF0 and resumé sorting systems that believe that men are more qualified to be programmers than women BIBREF1 . Similarly, sentiment and emotion analysis systems can also perpetuate and accentuate inappropriate human biases, e.g., systems that consider utterances from one race or gender to be less positive simply because of their race or gender, or customer support systems that prioritize a call from an angry male over a call from the equally angry female.\nPredictions of machine learning systems have also been shown to be of higher quality when dealing with information from some groups of people as opposed to other groups of people. For example, in the area of computer vision, gender classification systems perform particularly poorly for darker skinned females BIBREF2 . Natural language processing (NLP) systems have been shown to be poor in understanding text produced by people belonging to certain races BIBREF3 , BIBREF4 . For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.\nEven though there is some recent work highlighting such inappropriate biases (such as the work mentioned above), each such past work has largely focused on just one or two systems and resources. Further, there is no benchmark dataset for examining inappropriate biases in natural language systems. In this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC). We used the EEC as a supplementary test set in a recent shared task on predicting sentiment and emotion intensity in tweets, SemEval-2018 Task 1: Affect in Tweets BIBREF5 . In particular, we wanted to test a hypothesis that a system should equally rate the intensity of the emotion expressed by two sentences that differ only in the gender/race of a person mentioned. Note that here the term system refers to the combination of a machine learning architecture trained on a labeled dataset, and possibly using additional language resources. The bias can originate from any or several of these parts. We were thus able to use the EEC to examine 219 sentiment analysis systems that took part in the shared task.\nWe compare emotion and sentiment intensity scores that the systems predict on pairs of sentences in the EEC that differ only in one word corresponding to race or gender (e.g., `This man made me feel angry' vs. `This woman made me feel angry'). We find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender. We also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.\nDespite the work we describe here and what others have proposed in the past, it should be noted that there are no simple solutions for dealing with inappropriate human biases that percolate into machine learning systems. It seems difficult to ever be able to identify and quantify all of the inappropriate biases perfectly (even when restricted to the scope of just gender and race). Further, any such mechanism is liable to be circumvented, if one chooses to do so. Nonetheless, as developers of sentiment analysis systems, and NLP systems more broadly, we cannot absolve ourselves of the ethical implications of the systems we build. Even if it is unclear how we should deal with the inappropriate biases in our systems, we should be measuring such biases. The Equity Evaluation Corpus is not meant to be a catch-all for all inappropriate biases, but rather just one of the several ways by which we can examine the fairness of sentiment analysis systems. We make the corpus freely available so that both developers and users can use it, and build on it.\nWe also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.",

        "evidence": "In this section, we introduce the deep neural network architecture that we used to classify emotions in the tweets dataset. Emotional expressions are more complex and context-dependent even compared to other forms of expressions based mostly on the complexity and ambiguity of human emotions and emotional expressions and the huge impact of context on the understanding of the expressed emotion. These complexities are what led us to believe lexicon-based features like is normally used in conventional machine learning approaches are unable to capture the intricacy of emotional expressions.\nOur architecture was designed to show that using a model that captures better information about the context and sequential nature of the text can outperform lexicon-based methods commonly used in the literature. As mentioned in the Introduction, Recurrent Neural Networks (RNNs) have been shown to perform well for the verity of tasks in NLP, especially classification tasks. And as our goal was to capture more information about the context and sequential nature of the text, we decided to use a model based on bidirectional RNN, specifically a bidirectional GRU network to analyze the tweets.\nFor building the emotion classifier, we have decided to use 7 binary classifiers-one for each emotion- each of which uses the same architecture for detecting a specific emotion. You can see the plot diagram of the model in Figure FIGREF6 . The first layer consists of an embedding lookup layer that will not change during training and will be used to convert each term to its corresponding embedding vector. In our experiments, we tried various word embedding models but saw little difference in their performance. Here we report the results for two which had the best performance among all, ConceptNet Numberbatch BIBREF35 and fastText BIBREF36 both had 300 dimensions.\nAs none of our tweets had more than 35 terms, we set the size of the embedding layer to 35 and added padding to shorter tweets. The output of this layer goes to a bidirectional GRU layer selected to capture the entirety of each tweet before passing its output forward. The goal is to create an intermediate representation for the tweets that capture the sequential nature of the data. For the next step, we use a concatenation of global max-pooling and average-pooling layers (with a window size of two). Then a max-pooling was used to extract the most important features form the GRU output and an average-pooling layer was used to considers all features to create a representation for the text as a whole. These partial representations are then were concatenated to create out final hidden representation. For classification, the output of the concatenation is passed to a dense classification layer with 70 nodes along with a dropout layer with a rate of 50% to prevent over-fitting. The final layer is a sigmoid layer that generates the final output of the classifier returning the class probability.\nAnd as our goal was to capture more information about the context and sequential nature of the text, we decided to use a model based on bidirectional RNN, specifically a bidirectional GRU network to analyze the tweets.",

LSTMs BIBREF10 were designed for better remembering and memory accesses, which can also avoid the problem of gradient exploding or vanishing in the standard RNN. Be capable of incorporating context on both sides of every position in the input sequence, BLSTMs introduced in BIBREF11 , BIBREF12 have reported to achieve great performance in Handwriting Recognition BIBREF13 , and Machine Translation BIBREF14 tasks.\nGenerative adversarial networks (GANs) BIBREF15 are a class of generative models for learning how to produce images. Basically, GANs consist of a generator G and a discriminator D, which are trained based on game theory. G maps a input noise vector to an output image, while D takes in an image then outputs a prediction whether the input image is a sample generated by G. Recently, applications of GANs have shown that they can generate promising results BIBREF16 , BIBREF17 . Several recent papers have also extended GANs to the semi-supervised context BIBREF18 , BIBREF19 by simply increasing the dimension of the classifier output from INLINEFORM0 to INLINEFORM1 , which the samples of the extra class are generated by G.\nIn this paper, We proposed an end-to-end architecture named AC-BLSTM by combining the ACNN with the BLSTM for sentences and documents modeling. In order to make the model deeper, instead of using the normal convolution, we apply the technique proposed in BIBREF8 which employs a INLINEFORM0 convolution followed by a INLINEFORM1 convolution by spatial factorizing the INLINEFORM2 convolution. And we use the pretrained word2vec vectors BIBREF20 as the ACNN input, which were trained on 100 billion words of Google News to learn the higher-level representations of n-grams. The outputs of the ACNN are organized as the sequence window feature to feed into the multi-layer BLSTM. So our model does not rely on any other extra domain specific knowledge and complex preprocess, e.g. word segmentation, part of speech tagging and so on. We evaluate AC-BLSTM on sentence-level and document-level tasks including sentiment analysis, question type classification, and subjectivity classification. Experimental results demonstrate the effectiveness of our approach compared with other state-of-the-art methods. Further more, inspired by the ideas of extending GANs to the semi-supervised learning context by BIBREF18 , BIBREF19 , we propose a semi-supervised learning framework for text classification which further improve the performance of AC-BLSTM.\nThe rest of the paper is organized as follows. Section 2 presents a brief review of related work. Section 3 discusses the architecture of our AC-BLSTM and our semi-supervised framework. Section 4 presents the experiments result with comparison analysis. Section 5 concludes the paper.\nExperimental results demonstrate the effectiveness of our approach compared with other state-of-the-art methods.",

        "answer": "Evaluate their method on multiple benchmark tasks: natural language inference, paraphrase identification, sentiment classification, and machine translation.",
        "evidence": "In the field of natural language processing (NLP), the most prevalent neural approach to obtaining sentence representations is to use recurrent neural networks (RNNs), where words in a sentence are processed in a sequential and recurrent manner. Along with their intuitive design, RNNs have shown outstanding performance across various NLP tasks e.g. language modeling BIBREF0 , BIBREF1 , machine translation BIBREF2 , BIBREF3 , BIBREF4 , text classification BIBREF5 , BIBREF6 , and parsing BIBREF7 , BIBREF8 .\nAmong several variants of the original RNN BIBREF9 , gated recurrent architectures such as long short-term memory (LSTM) BIBREF10 and gated recurrent unit (GRU) BIBREF2 have been accepted as de-facto standard choices for RNNs due to their capability of addressing the vanishing and exploding gradient problem and considering long-term dependencies. Gated RNNs achieve these properties by introducing additional gating units that learn to control the amount of information to be transferred or forgotten BIBREF11 , and are proven to work well without relying on complex optimization algorithms or careful initialization BIBREF12 .\nMeanwhile, the common practice for further enhancing the expressiveness of RNNs is to stack multiple RNN layers, each of which has distinct parameter sets (stacked RNN) BIBREF13 , BIBREF14 . In stacked RNNs, the hidden states of a layer are fed as input to the subsequent layer, and they are shown to work well due to increased depth BIBREF15 or their ability to capture hierarchical time series BIBREF16 which are inherent to the nature of the problem being modeled.\nHowever this setting of stacking RNNs might hinder the possibility of more sophisticated recurrence-based structures since the information from lower layers is simply treated as input to the next layer, rather than as another class of state that participates in core RNN computations. Especially for gated RNNs such as LSTMs and GRUs, this means that layer-to-layer connections cannot fully benefit from the carefully constructed gating mechanism used in temporal transitions. Some recent work on stacking RNNs suggests alternative methods that encourage direct and effective interaction between RNN layers by adding residual connections BIBREF17 , BIBREF18 , by shortcut connections BIBREF18 , BIBREF19 , or by using cell states of LSTMs BIBREF20 , BIBREF21 .\nIn this paper, we propose a method of constructing multi-layer LSTMs where cell states are used in controlling the vertical information flow. This system utilizes states from the left and the lower context equally in computation of the new state, thus the information from lower layers is elaborately filtered and reflected through a soft gating mechanism. Our method is easy-to-implement, effective, and can replace conventional stacked LSTMs without much modification of the overall architecture.\nWe call the proposed architecture Cell-aware Stacked LSTM, or CAS-LSTM, and evaluate our method on multiple benchmark datasets: SNLI BIBREF22 , MultiNLI BIBREF23 , Quora Question Pairs BIBREF24 , and SST BIBREF25 . From experiments we show that the CAS-LSTMs consistently outperform typical stacked LSTMs, opening the possibility of performance improvement of architectures that use stacked LSTMs.\nOur contribution is summarized as follows.\nThis paper is organized as follows. We give a detailed description about the proposed method in § SECREF2 . Experimental results are given in § SECREF3 . We study prior work related to our objective in § SECREF4 and conclude in § SECREF5 .\nWe call this architecture Cell-aware Stacked LSTM, or CAS-LSTM, and evaluate our method on multiple benchmark tasks: natural language inference, paraphrase identification, sentiment clas sification, and machine translation.",

        "answer": "The evaluation of downstream tasks from different sources needs to be studied.",
        "evidence": "In this paper, we propose a novel deep learning model for Thai sentence segmentation. This study makes three main contributions. The first contribution is to integrate a local representation based on n-gram embedding into our deep model. This approach helps to capture word groups near sentence boundaries, allowing the model to identify boundaries more accurately. Second, we integrate a distant representation obtained from self-attention modules to capture sentence contextual information. This approach allows the model to focus on the initial words of dependent clauses (i.e., ”Before”, ”If”, and ”Although”). The last contribution is an adaptation of CVT, which allows the model to utilize unlabeled data to produce effective local and distant representations.\nThe experiment was conducted on two Thai datasets, Orchid and UGWC, and one English punctuation restoration dataset, IWSLT. English punctuation restoration is similar to our Thai sentence segmentation. On the Thai sentence segmentation task, our model achieves F1 scores of 92.5% and 88.9% on the Orchid and UGWC datasets, constituting a relative error reduction of 7.4% and 10.5%, respectively. On the English punctuation task, the 2-class F1 score reached 82.7% when considering only two punctuation classes (making the task similar to sentence segmentation in Thai). Moreover, our model outperforms the model integrated with pretrained word vectors in terms of the overall F1 score on the IWSLT dataset. Based on our contributions, the local representation scheme has the highest impact on the Thai corpus, while the distant representation and CVT result in strong improvements on the English dataset.\nMoreover, our model can also be applied to elementary discourse unit (EDU) segmentation, which is used as the minimal syntactic unit for downstream tasks such as text summarization and machine translation. However, no experiments have been conducted to determine how different sentences and EDUs affect downstream tasks. Therefore, the evaluation of downstream tasks from different sources needs to be studied.\nHowever, no experiments have been conducted to determine how different sentences and EDUs affect downstream tasks.

        "evidence": "Low dimensional word representations (embeddings) have become a key component in modern NLP systems for language modeling, parsing, sentiment classification, and many others. These embeddings are usually derived by employing the distributional hypothesis: that similar words appear in similar contexts BIBREF0 .\nThe models that perform the word embedding can be divided into two classes: predictive, which learn a target or context word distribution, and counting, which use a raw, weighted, or factored word-context co-occurrence matrix BIBREF1 . The most well-known predictive model, which has become eponymous with word embedding, is word2vec BIBREF2 . Popular counting models include PPMI-SVD BIBREF3 , GloVe BIBREF4 , and LexVec BIBREF5 .\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.\nfastText BIBREF6 addresses these issues in the Skip-gram word2vec model by representing a word by the sum of a unique vector and a set of shared character n-grams (from hereon simply referred to as n-grams) vectors. This addresses both issues above as learned information is shared through the n-gram vectors and from these OOV word representations can be constructed.\nIn this paper we propose incorporating subword information into counting models using a strategy similar to fastText.\nWe use LexVec as the counting model as it generally outperforms PPMI-SVD and GloVe on intrinsic and extrinsic evaluations BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , but the method proposed here should transfer to GloVe unchanged.\nThe LexVec objective is modified such that a word's vector is the sum of all its subword vectors.\nWe compare 1) the use of n-gram subwords, like fastText, and 2) unsupervised morphemes identified using Morfessor BIBREF11 to learn whether more linguistically motivated subwords offer any advantage over simple n-grams.\nTo evaluate the impact subword information has on in-vocabulary (IV) word representations, we run intrinsic evaluations consisting of word similarity and word analogy tasks. The incorporation of subword information results in similar gains (and losses) to that of fastText over Skip-gram. Whereas incorporating n-gram subwords tends to capture more syntactic information, unsupervised morphemes better preserve semantics while also improving syntactic results. Given that intrinsic performance can correlate poorly with performance on downstream tasks BIBREF12 , we also conduct evaluation using the VecEval suite of tasks BIBREF13 , in which\nall subword models, including fastText, show no significant improvement over word-level models.\nWe verify the model's ability to represent OOV words by quantitatively evaluating nearest-neighbors. Results show that, like fastText, both LexVec n-gram and (to a lesser degree) unsupervised morpheme models give coherent answers.\nThis paper discusses related word ( $§$ \"Related Work\" ), introduces the subword LexVec model ( $§$ \"Subword LexVec\" ), describes experiments ( $§$ \"Materials\" ), analyzes results ( $§$ \"Results\" ), and concludes with ideas for future works ( $§$ \"Conclusion and Future Work\" ).\nThese models all learn word-level representations, which presents two main problems: 1) Learned information is not explicitly shared among the representations as each word has an independent vector. 2) There is no clear way to represent out-of-vocabulary (OOV) words.",

Jiang was paramount leader of China from 1989 to 2002. He was the core leader of the third generation of Chinese leadership, one of four core leaders alongside Mao Zedong, Deng Xiaoping and Xi Jinping.\n\nBorn in Yangzhou, Jiangsu, Jiang joined the CCP while he was in college. After the establishment of the People's Republic of China in 1949, he received training at the Stalin Automobile Works in Moscow in the 1950s, later returning to Shanghai in 1962 to serve in various institutes, later being sent between 1970-1972 to Romania as part of an expert team to establish machinery manufacturing plants in the country. After 1979, he was appointed as the vice chair of two commissions by vice premier Gu Mu to oversee the newly-established special economic zones (SEZs). He became the vice minister of the newly-established Ministry of Electronics Industry and a member of the CCP Central Committee in 1982.\n\nJiang was appointed as the mayor of Shanghai in 1985, later being promoted to its Communist Party secretary, as well as a member of the CCP Politburo, in 1987. Jiang came to power unexpectedly as a compromise candidate following the 1989 Tiananmen Square protests and massacre, when he replaced Zhao Ziyang as CCP general secretary after Zhao was ousted for his support for the student movement. As the involvement of the \"Eight Elders\" in Chinese politics steadily declined, Jiang consolidated his hold on power to become the \"paramount leader\" in the country during the 1990s. Urged by Deng Xiaoping's southern tour in 1992, Jiang officially introduced the term \"socialist market economy\" in his speech during the 14th CCP National Congress held later that year, which accelerated \"opening up and reform\".\n\nUnder Jiang's leadership, China experienced substantial economic growth with the continuation of market reforms. The returning of Hong Kong from the United Kingdom in 1997 and of Macau from Portugal in 1999, and entry into the World Trade Organisation in 2001, were landmark moments of his era. China also witnessed improved relations with the outside world, while the Communist Party maintained its tight control over the state. Jiang faced criticism over human rights abuses, including the crackdown on the Falun Gong movement. His contributions to party doctrine, known as the \"Three Represents\", were written into the CCP constitution in 2002. Jiang gradually vacated his official leadership titles from 2002 to 2005, being succeeded in these roles by Hu Jintao, although he and his political faction continued to influence affairs until much later.

        "evidence": "The Indus Valley Civilisation (IVC), also known as the Indus Civilisation was a Bronze Age civilisation in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE, and in its mature form 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread. Its sites spanned an area from much of Pakistan, to northeast Afghanistan, and northwestern India. The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan.\n\nThe term Harappan is sometimes applied to the Indus civilisation after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab province of British India and is now Punjab, Pakistan. The discovery of Harappa and soon afterwards Mohenjo-daro was the culmination of work that had begun after the founding of the Archaeological Survey of India in the British Raj in 1861. There were earlier and later cultures called Early Harappan and Late Harappan in the same area. The early Harappan cultures were populated from Neolithic cultures, the earliest and best-known of which is Mehrgarh, in Balochistan, Pakistan. Harappan civilisation is sometimes called Mature Harappan to distinguish it from the earlier cultures.\n\nThe cities of the ancient Indus were noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, clusters of large non-residential buildings, and techniques of handicraft and metallurgy. Mohenjo-daro and Harappa very likely grew to contain between 30,000 and 60,000 individuals, and the civilisation may have contained between one and five million individuals during its florescence. A gradual drying of the region during the 3rd millennium BCE may have been the initial stimulus for its urbanisation. Eventually it also reduced the water supply enough to cause the civilisation's demise and to disperse its population to the east.\n\nAlthough over a thousand Mature Harappan sites have been reported and nearly a hundred excavated, there are five major urban centres: Mohenjo-daro in the lower Indus Valley (declared a UNESCO World Heritage Site in 1980 as \"Archaeological Ruins at Moenjodaro\"), Harappa in the western Punjab region, Ganeriwala in the Cholistan Desert, Dholavira in western Gujarat (declared a UNESCO World Heritage Site in 2021 as \"Dholavira: A Harappan City\"), and Rakhigarhi in Haryana. The Harappan language is not directly attested, and its affiliation uncertain as the Indus script has remained undeciphered. A relationship with the Dravidian or Elamo-Dravidian language family is favoured by a section of scholars.",

Our proposed model which combines structured answer-relevant relations and unstructured sentences achieves significant improvements over proximity-based answer-aware models BIBREF9, BIBREF15 on both dataset splits. Presumably, our structured answer-relevant relation is a generalization of the context explored by the proximity-based methods because they can only capture short dependencies around answer fragments while our extractions can capture both short and long dependencies given the answer fragments. Moreover, our proposed framework is a general one to jointly leverage structured relations and unstructured sentences. All compared baseline models which only consider unstructured sentences can be further enhanced under our framework.\nRecall that existing proximity-based answer-aware models perform poorly when the distance between the answer fragment and other non-stop sentence words that also appear in the ground truth question is large (Table TABREF2). Here we investigate whether our proposed model using the structured answer-relevant relations can alleviate this issue or not, by conducting experiments for our model under the same setting as in Table TABREF2. The broken-down performances by different relative distances are shown in Table TABREF40. We find that our proposed model outperforms Hybrid (our re-implemented version for this experiment) on all ranges of relative distances, which shows that the structured answer-relevant relations can capture both short and long term answer-relevant dependencies of the answer in sentences. Furthermore, comparing the performance difference between Hybrid and our model, we find the improvements become more significant when the distance increases from “$0\\sim 10$” to “$>10$”. One reason is that our model can extract relations with distant dependencies to the answer, which greatly helps our model ignore the extraneous information. Proximity-based answer-aware models may overly emphasize the neighboring words of answers and become less effective as the useful context becomes further away from the answer in the complex sentences. In fact, the breakdown intervals in Table TABREF40 naturally bound its sentence length, say for “$>10$”, the sentences in this group must be longer than 10. Thus, the length variances in these two intervals could be significant. To further validate whether our model can extract long term dependency words. We rerun the analysis of Table TABREF40 only for long sentences (length $>$ 20) of each interval. The improvement percentages over Hybrid are shown in Table TABREF40, which become more significant when the distance increases from “$0\\sim 10$” to “$>10$”.\nOur proposed model which combines structured answer-relevant relations and unstructured sentences achieves significant improvements over proximity-based answer-aware models (Zhou et al., 2017; Sun et al., 2018) on both dataset splits.",

        "answer": "Natural language processing tasks on Twitter.",
        "evidence": "In recent years, the micro-blogging site Twitter has become a major social media platform with hundreds of millions of users. The short (140 character limit), noisy and idiosyncratic nature of tweets make standard information retrieval and data mining methods ill-suited to Twitter. Consequently, there has been an ever growing body of IR and data mining literature focusing on Twitter. However, most of these works employ extensive feature engineering to create task-specific, hand-crafted features. This is time consuming and inefficient as new features need to be engineered for every task.\nIn this paper, we present Tweet2Vec, a method for generating general-purpose vector representation of tweets that can be used for any classification task. Tweet2Vec removes the need for expansive feature engineering and can be used to train any standard off-the-shelf classifier (e.g., logistic regression, svm, etc). Tweet2Vec uses a CNN-LSTM encoder-decoder model that operates at the character level to learn and generate vector representation of tweets. Our method is especially useful for natural language processing tasks on Twitter where it is particularly difficult to engineer features, such as speech-act classification and stance detection (as shown in our previous works on these topics BIBREF0 , BIBREF1 ).\nThere has been several works on generating embeddings for words, most famously Word2Vec by Mikolov et al. BIBREF2 ). There has also been a number of different works that use encoder-decoder models based on long short-term memory (LSTM) BIBREF3 , and gated recurrent neural networks (GRU) BIBREF4 . These methods have been used mostly in the context of machine translation. The encoder maps the sentence from the source language to a vector representation, while the decoder conditions on this encoded vector for translating it to the target language. Perhaps the work most related to ours is the work of Le and Mikolov le2014distributed, where they extended the Word2Vec model to generate representations for sentences (called ParagraphVec). However, these models all function at the word level, making them ill-suited to the extremely noisy and idiosyncratic nature of tweets. Our character-level model, on the other hand, can better deal with the noise and idiosyncrasies in tweets. We plan to make our model and the data used to train it publicly available to be used by other researchers that work with tweets.\nOur method is especially useful for natural language processing tasks on Twitter where it is particularly difficult to engineer features, such as speech-act classification and stance detection (as shown in our previous works on these topics [13, 12]).",

For example, the S&P 500 experienced a dramatic fall in mid 2007, from which it recovered completely by early 2013. Investors who had purchased 10-year Treasuries in 2006 would have received a safe and steady yield until 2015, possibly achieving better returns than those investing in equities during that volatile period.\n\nEconomist Campbell Harvey's 1986 dissertation showed that an inverted yield curve accurately forecasts U.S. recessions. An inverted curve has indicated a worsening economic situation in the future eight times since 1970.\n\nIn addition to potentially signaling an economic decline, inverted yield curves also imply that the market believes inflation will remain low. This is because, even if there is a recession, a low bond yield will still be offset by low inflation. However, technical factors, such as a flight to quality or global economic or currency situations, may cause an increase in demand for bonds on the long end of the yield curve, causing long-term rates to fall.

Lincoln led the Union through the American Civil War to defend the nation as a constitutional union and succeeded in abolishing slavery, bolstering the federal government, and modernizing the U.S. economy.\n\nLincoln was born into poverty in a log cabin in Kentucky and was raised on the frontier, primarily in Indiana. He was self-educated and became a lawyer, Whig Party leader, Illinois state legislator, and U.S. Congressman from Illinois. In 1849, he returned to his successful law practice in central Illinois. In 1854, he was angered by the Kansas–Nebraska Act, which opened the territories to slavery, and he re-entered politics. He soon became a leader of the new Republican Party. He reached a national audience in the 1858 Senate campaign debates against Stephen A. Douglas. Lincoln ran for president in 1860, sweeping the North to gain victory. Pro-slavery elements in the South viewed his election as a threat to slavery, and Southern states began seceding from the nation. During this time, the newly formed Confederate States of America began seizing federal military bases in the south.

        "answer": "They present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations.",
        "evidence": "Multi-document summarization (MDS), the transformation of a set of documents into a short text containing their most important aspects, is a long-studied problem in NLP. Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ). We make these resources publicly available under a permissive license.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations.",

It was supposed that if expressions from the same similarity set co-occur in the same document then their contribution into the document's topics is really more than it is presented with their frequencies, therefore their frequencies should be increased. In such an approach, the algorithm can \"see\" similarities between different multiword expressions with the same component word.\nIn our approach, at first, we include related single words and phrases from a thesaurus such as WordNet or EuroVoc in these similarity sets. Then, we add preliminarily extracted ngrams into these sets and, this way, we use two different sources of external knowledge. We use the same LDA-SIM algorithm as described in BIBREF16 but study what types of semantic relations can be introduced into such similarity sets and be useful for improving topic models.

        "answer": "A neural network pretrained.",
        "evidence": "The cognitive processes involved in human language comprehension are complex and only partially identified. According to the dual-stream model of speech comprehension BIBREF1 , sound waves are first converted to phoneme-like features and further processed by a ventral stream that maps those features onto words and semantic structures, and a dorsal stream that (among other things) supports audio-short term memory. The mapping of words onto meaning is thought to be subserved by widely distributed regions of the brain that specialize in particular modalities — for example visual aspects of the word banana reside in the occipital lobe of the brain and are activated when the word banana is heard BIBREF2 — and the different representation modalities are thought to be integrated into a single coherent latent representation in the anterior temporal lobe BIBREF3 . While this part of meaning representation in human language comprehension is somewhat understood, much less is known about how the meanings of words are integrated together to form the meaning of sentences and discourses. One tool researchers use to study the integration of meaning across words is electroencephelography (EEG), which measures the electrical activity of large numbers of neurons acting in concert. EEG has the temporal resolution necessary to study the processes involved in meaning integration, and certain stereotyped electrical responses to word presentations, known as event-related potentials (ERPs), have been identified with some of the processes thought to contribute to comprehension.\n\nIn this work, we consider six ERP components that have been associated in the cognitive neuroscience and psycholinguistics literature with language processing and which we analyze in the data from BIBREF0 (see Figure FIGREF1 for spatial and temporal definitions of these ERP components). Three of these — the N400, EPNP, and PNP responses — are primarily considered markers for semantic processing, while the other three — the P600, ELAN, and LAN responses — are primarily considered markers for syntactic processing. However, the neat division of the ERP responses into either semantic or syntactic categories is controversial. The N400 response has been very well studied (for an overview see BIBREF4 ) and it is well established that it is associated with semantic complexity, but the features of language that trigger the other ERP responses we consider here are poorly understood. We propose to use a neural network pretrained as a language model to probe what features of language drive these ERP responses, and in turn to probe what features of language mediate the cognitive processes that underlie human language comprehension, and especially the integration of meaning across words.\nWe propose to use a neural network pretrained as a language model to probe what features of language drive these ERP responses, and in turn to probe what features of language mediate the cognitive processes that underlie human language comprehension, and especially the integration of meaning across words.",

During the Chinese Warring States period, the Dujiangyan irrigation system was built by the Qin as a water conservation and flood control project. The system's infrastructure is located on the Minjiang (Chinese: 岷江; pinyin: Mínjiāng), which is the longest tributary of the Chang Jiang, in Sichuan, China.\n\nThe Mississippi levee system represents one of the largest such systems found anywhere in the world. It comprises over 5,600 km (3,500 mi) of levees extending some 1,000 km (620 mi) along the Mississippi, stretching from Cape Girardeau, Missouri, to the Mississippi delta. They were begun by French settlers in Louisiana in the 18th century to protect the city of New Orleans. The first Louisiana levees were about 90 cm (3 ft) high and covered a distance of about 80 km (50 mi) along the riverside. The U.S. Army Corps of Engineers, in conjunction with the Mississippi River Commission, extended the levee system beginning in 1882 to cover the riverbanks from Cairo, Illinois to the mouth of the Mississippi delta in Louisiana. By the mid-1980s, they had reached their present extent and averaged 7.3 m (24 ft) in height; some Mississippi levees are as high as 15 m (50 ft). The Mississippi levees also include some of the longest continuous individual levees in the world. One such levee extends southwards from Pine Bluff, Arkansas, for a distance of some 610 km (380 mi). The scope and scale of the Mississippi levees has often been compared to the Great Wall of China.\n\nThe United States Army Corps of Engineers (USACE) recommends and supports cellular confinement technology (geocells) as a best management practice. Particular attention is given to the matter of surface erosion, overtopping prevention and protection of levee crest and downstream slope. Reinforcement with geocells provides tensile force to the soil to better resist instability.\n\nArtificial levees can lead to an elevation of the natural river bed over time; whether this happens or not and how fast, depends on different factors, one of them being the amount and type of the bed load of a river. Alluvial rivers with intense accumulations of sediment tend to this behavior. Examples of rivers where artificial levees led to an elevation of the river bed, even up to a point where the river bed is higher than the adjacent ground surface behind the levees, are found for the Yellow River in China and the Mississippi in the United States.",

        "evidence": "We automatically create a test set from the OpenSubtitles corpus BIBREF22 . The goal is to provide a large number of difficult test cases where an English pronoun has to be translated to a German pronoun.\nThe most challenging cases are translating it to either er, sie or es, depending on the grammatical gender of the antecedent. Not only is the translation of it ambiguous, there is also class imbalance in the training data (see Table TABREF18 ). There is roughly a 30% probability that it is aligned to es, which makes it difficult to learn to translate er and sie. We use parsing and automatic co-reference resolution to find translation pairs that satisfy our constraints.\nTo provide a basis for filtering with constraints, we tokenize the whole data set with the Moses tokenizer, generate symmetric word alignments with fast_align BIBREF23 , parse the English text with CoreNLP BIBREF24 , parse the German text with ParZu BIBREF25 and perform coreference resolution on both sides. The coreference chains are obtained with the neural model of CoreNLP for English, and with CorZu for German BIBREF26 , respectively.\nThen we opt for high-precision, aggressive filtering, according to the following protocol: for each pair of sentences INLINEFORM0 in English and German, extract iff\n INLINEFORM0 contains the English pronoun it, and INLINEFORM1 contains a German pronoun that is third person singular (er, sie or es), as indicated by their part-of-speech tags;\nthose pronouns are aligned to each other;\nboth pronouns are in a coreference chain;\ntheir nominal antecedents in the coreference chain are aligned on word level.\nThis removes most candidate pairs, but is necessary to overcome the noise introduced by our preprocessing pipeline, most notably coreference resolution. From the filtered set, we create a balanced test set by randomly sampling 4000 instances of each of the three translations of it under consideration (er, sie, es). We do not balance antecedent distance. See Table TABREF25 for the distribution of pronoun pairs and antecedent distance in the test set.\nFor each sentence pair in the resulting test set, we introduce contrastive translations. A contrastive translation is a translation variant where the correct pronoun is swapped with an incorrect one. For an example, see Table TABREF19 , where the pronoun it in the original translation corresponds to sie because the antecedent bat is a feminine noun in German (Fledermaus). We produce wrong translations by replacing sie with one of the other pronouns (er, es).\nNote that, by themselves, these contrastive translations are grammatically correct if the antecedent is outside the current sentence. The test set also contains pronouns with an antecedent in the same sentence (antecedent distance 0). Those examples do not require any additional context for disambiguation and we therefore expect the sentence-level baseline to perform well on them.\nWe take extra care to ensure that the resulting contrastive translations are grammatically correct, because ungrammatical sentences are easily dismissed by an NMT system. For instance, if there are any possessive pronouns (such as seine) in the sentence, we also change their gender to match the personal pronoun replacement.\nThe German coreference resolution system does not resolve es because most instances of es in German are either non-referential forms, or they refer to a clause instead of a nominal antecedent. We limit the test set to nominal antecedents, as these are the only ambiguous cases with respect to translation. For this reason, we have to rely entirely on the English coreference links for the extraction of sentence pairs with it INLINEFORM0 es, as opposed to pairs with it INLINEFORM1 er and it INLINEFORM2 sie where we have coreference chains in both languages.\nOur extraction process respects document boundaries, to ensure we always search for the right context. We extract additional information from the annotated documents, such as the distance (in sentences) between pronouns and their antecedents, the document of origin, lemma, morphology and dependency information if available.\nThen we opt for high-precision, aggressive filtering, according to the following protocol: for each pair of sentences (e, f) in English and German, extract iff • e contains the English pronoun it, and f contains a German pronoun that is third person singular (er, sie or es), as indicated by their part-of-speech tags; • those pronouns are aligned to each other; • both pronouns are in a coreference chain; • their nominal antecedents in the coreference chain are aligned on word level.",

        "evidence": "Figure 1 illustrates the overall architecture of the discourse-level neural network model that consists of two Bi-LSTM layers, one max-pooling layer in between and one softmax prediction layer. The input of the neural network model is a paragraph containing a sequence of discourse units, while the output is a sequence of discourse relations with one relation between each pair of adjacent discourse units.\nGiven the words sequence of one paragraph as input, the lower Bi-LSTM layer will read the whole paragraph and calculate hidden states as word representations, and a max-pooling layer will be applied to abstract the representation of each discourse unit based on individual word representations. Then another Bi-LSTM layer will run over the sequence of discourse unit representations and compute new representations by further modeling semantic dependencies between discourse units within paragraph. The final softmax prediction layer will concatenate representations of two adjacent discourse units and predict the discourse relation between them.\nWord Vectors as Input: The input of the paragraph-level discourse relation prediction model is a sequence of word vectors, one vector per word in the paragraph. In this work, we used the pre-trained 300-dimension Google English word2vec embeddings. For each word that is not in the vocabulary of Google word2vec, we will randomly initialize a vector with each dimension sampled from the range $[-0.25, 0.25]$ . In addition, recognizing key entities and discourse connective phrases is important for discourse relation recognition, therefore, we concatenate the raw word embeddings with extra linguistic features, specifically one-hot Part-Of-Speech tag embeddings and one-hot named entity tag embeddings.\nBuilding Discourse Unit Representations: We aim to build discourse unit (DU) representations that sufficiently leverage cues for discourse relation prediction from paragraph-wide contexts, including the preceding and following discourse units in a paragraph. To process long paragraph-wide contexts, we take a bottom-up two-level abstraction approach and progressively generate a compositional representation of each word first (low level) and then generate a compositional representation of each discourse unit (high level), with a max-pooling operation in between. At both word-level and DU-level, we choose Bi-LSTM as our basic component for generating compositional representations, mainly considering its capability to capture long-distance dependencies between words (discourse units) and to incorporate influences of context words (discourse units) in each side.\nGiven a variable-length words sequence $X = (x_1,x_2,...,x_L)$ in a paragraph, the word-level Bi-LSTM will process the input sequence by using two separate LSTMs, one process the word sequence from the left to right while the other follows the reversed direction. Therefore, at each word position $t$ , we obtain two hidden states $\\overrightarrow{h_t}, \\overleftarrow{h_t}$ . We concatenate them to get the word representation $h_t = [\\overrightarrow{h_t}, \\overleftarrow{h_t}]$ . Then we apply max-pooling over the sequence of word representations for words in a discourse unit in order to get the discourse unit embedding: \n$$MP_{DU}[j] = \\max _{i=DU\\_start}^{DU\\_end}h_i[j]\\quad \\\\\nwhere, 1 \\le j \\le hidden\\_node\\_size$$   (Eq. 8) \nNext, the DU-level Bi-LSTM will process the sequence of discourse unit embeddings in a paragraph and generate two hidden states $\\overrightarrow{hDU_t}$ and $\\overleftarrow{hDU_t}$ at each discourse unit position. We concatenate them to get the discourse unit representation $hDU_t = [\\overrightarrow{hDU_t}, \\overleftarrow{hDU_t}]$ .\nThe Softmax Prediction Layer: Finally, we concatenate two adjacent discourse unit representations $hDU_{t-1}$ and $hDU_t$ and predict the discourse relation between them using a softmax function:\n$$y_{t-1} = softmax(W_y*[hDU_{t-1},hDU_t]+b_y)$$   (Eq. 9) \nFigure 1 illustrates the overall architecture of the discourse-level neural network model that consists of two Bi-LSTM layers, one max-pooling layer in between and one softmax prediction layer.",

For the gender classification task, we manually label an in-house dataset of 1,100 users with gender tags, including 550 female users, 550 male users. We obtain 162,829 tweets by crawling the 1,100 users' timelines.\nFor the dialect identification task, we randomly sample 20,000 tweets for each class from an in-house dataset gold labeled with the same 15 classes as the shared task.",

        "answer": "There are many ways to determine who the best soccer player is at the current time.\n\nSome would say that the Ballon d'Or award does that job for us, labeling the best player in the game at the current time. At this juncture, that is Karim Benzema of Real Madrid, who won the 2021/22 award after leading Los Blancos to the La Liga and Champions League double.\n\nOthers would say that the highest-paid player is the best. That would be Kylian Mbappe whose new PSG contract could see the French side shell out an eye-watering €630 million over the course of his new three-year contract he signed in the summer of 2022. Mbappe is thought to be the best young player in the game now, gracing the cover of the popular FIFA video game for the last two years.\n\nStill more could argue that the player with the most goals scored would be the best player. That would make Cristiano Ronaldo the top player in the world, with his all-time record of more than 800 goals for club and country. Right behind him is his rival Lionel Messi, who also has collected far more assists than his Portuguese counterpart. Young striker Erling Haaland may have something to say about that, however, as his incredible start to the Premier League season has seen him on pace to shatter the league's single-season goalscoring record.\n\nHowever, that seems to discount those who play other positions, like 2018 Ballon d'Or winner Luka Modric, whose midfield brilliance led Croatia to the last World Cup final, or 2022 Yashin trophy winner Thibaut Courtois, whose goalkeeping heroics earned him Man of the Match in the 2022 Champions League final.",

        "evidence": "In this section, we introduce the deep neural network architecture that we used to classify emotions in the tweets dataset. Emotional expressions are more complex and context-dependent even compared to other forms of expressions based mostly on the complexity and ambiguity of human emotions and emotional expressions and the huge impact of context on the understanding of the expressed emotion. These complexities are what led us to believe lexicon-based features like is normally used in conventional machine learning approaches are unable to capture the intricacy of emotional expressions.\nOur architecture was designed to show that using a model that captures better information about the context and sequential nature of the text can outperform lexicon-based methods commonly used in the literature. As mentioned in the Introduction, Recurrent Neural Networks (RNNs) have been shown to perform well for the verity of tasks in NLP, especially classification tasks. And as our goal was to capture more information about the context and sequential nature of the text, we decided to use a model based on bidirectional RNN, specifically a bidirectional GRU network to analyze the tweets.\nFor building the emotion classifier, we have decided to use 7 binary classifiers-one for each emotion- each of which uses the same architecture for detecting a specific emotion. You can see the plot diagram of the model in Figure FIGREF6 . The first layer consists of an embedding lookup layer that will not change during training and will be used to convert each term to its corresponding embedding vector. In our experiments, we tried various word embedding models but saw little difference in their performance. Here we report the results for two which had the best performance among all, ConceptNet Numberbatch BIBREF35 and fastText BIBREF36 both had 300 dimensions.\nAs none of our tweets had more than 35 terms, we set the size of the embedding layer to 35 and added padding to shorter tweets. The output of this layer goes to a bidirectional GRU layer selected to capture the entirety of each tweet before passing its output forward. The goal is to create an intermediate representation for the tweets that capture the sequential nature of the data. For the next step, we use a concatenation of global max-pooling and average-pooling layers (with a window size of two). Then a max-pooling was used to extract the most important features form the GRU output and an average-pooling layer was used to considers all features to create a representation for the text as a whole. These partial representations are then were concatenated to create out final hidden representation. For classification, the output of the concatenation is passed to a dense classification layer with 70 nodes along with a dropout layer with a rate of 50% to prevent over-fitting. The final layer is a sigmoid layer that generates the final output of the classifier returning the class probability.\nThen a max-pooling was used to extract the most important features form the GRU output and an average-pooling layer was used to considers all features to create a representation for the text as a whole.",

        "answer": "This is due to the fact that in these evaluation frameworks, the topics’ top elements contain a lot of multiword expressions, which rarely occur in Wikipedia, used for the coherence calculation, therefore the utilized automatic coherence measures can have insufficient evidence for correct estimates.",
        "evidence": "For evaluating topics with automatic quality measures, we used several English text collections and one Russian collection (Table TABREF7 ). We experiment with three thesauri: WordNet (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms), and Russian thesaurus RuThes (115 thousand entries) BIBREF19 .\nAt the preprocessing step, documents were processed by morphological analyzers. Also, we extracted noun groups as described in BIBREF16 . As baselines, we use the unigram LDA topic model and LDA topic model with added 1000 ngrams with maximal NC-value BIBREF20 extracted from the collection under analysis.\nAs it was found before BIBREF14 , BIBREF16 , the addition of ngrams without accounting relations between their components considerably worsens the perplexity because of the vocabulary growth (for perplexity the less is the better) and practically does not change other automatic quality measures (Table 2).\nWe add the Wordnet data in the following steps. At the first step, we include WordNet synonyms (including multiword expressions) into the proposed similarity sets (LDA-Sim+WNsyn). At this step, frequencies of synonyms found in the same document are summed up in process LDA topic learning as described in Algorithm SECREF3 . We can see that the kernel uniqueness becomes very low, topics are very close to each other in content (Table 2: LDA-Sim+WNsyn). At the second step, we add word direct relatives (hyponyms, hypernyms, etc.) to similarity sets. Now the frequencies of semantically related words are added up enhancing the contribution into all topics of the current document.\nThe Table 2 shows that these two steps lead to great degradation of the topic model in most measures in comparison to the initial unigram model: uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times (Table 2: LDA-Sim+WNsynrel). It is evident that at this step the model has a poor quality. When we look at the topics, the cause of the problem seems to be clear. We can see the overgeneralization of the obtained topics. The topics are built around very general words such as \"person\", \"organization\", \"year\", etc. These words were initially frequent in the collection and then received additional frequencies from their frequent synonyms and related words.\nThen we suppose that these general words were used in texts to discuss specific events and objects, therefore, we change the constructions of the similarity sets in the following way: we do not add word hyponyms to its similarity set. Thus, hyponyms, which are usually more specific and concrete, should obtain additional frequencies from upper synsets and increase their contributions into the document topics. But the frequencies and contribution of hypernyms into the topic of the document are not changed. And we see the great improvement of the model quality: the kernel uniqueness considerably improves, perplexity decreases to levels comparable with the unigram model, topic coherence characteristics also improve for most collections (Table 2:LDA-Sim+WNsynrel/hyp).\nWe further use the WordNet-based similarity sets with n-grams having the same components as described in BIBREF16 . All measures significantly improve for all collections (Table 2:LDA-Sim+WNsr/hyp+Ngrams). At the last step, we try to apply the same approach to ngrams that was previously utilized to hyponym-hypernym relations: frequencies of shorter ngrams and words are summed to frequencies of longer ngrams but not vice versa. In this case we try to increase the contribution of more specific longer ngrams into topics. It can be seen (Table 2) that the kernel uniqueness grows significantly, at this step it is 1.3-1.6 times greater than for the baseline models achieving 0.76 on the ACL collection (Table 2:LDA-Sim+WNsr/hyp+Ngrams/l).\nAt the second series of the experiments, we applied EuroVoc information retrieval thesaurus to two European Union collections: Europarl and JRC. In content, the EuroVoc thesaurus is much smaller than WordNet, it contains terms from economic and political domains and does not include general abstract words. The results are shown in Table 3. It can be seen that inclusion of EuroVoc synsets improves the topic coherence and increases kernel uniqueness (in contrast to results with WordNet). Adding ngrams further improves the topic coherence and kernel uniqueness.\nAt last we experimented with the Russian banking collection and utilized RuThes thesaurus. In this case we obtained improvement already on RuThes synsets and again adding ngrams further improved topic coherence and kernel uniqueness (Table 4).\nIt is worth noting that adding ngrams sometimes worsens the TC-NPMI measure, especially on the JRC collection. This is due to the fact that in these evaluation frameworks, the topics' top elements contain a lot of multiword expressions, which rarely occur in Wikipedia, used for the coherence calculation, therefore the utilized automatic coherence measures can have insufficient evidence for correct estimates.\nIt is worth noting that adding ngrams sometimes worsens the TC-NPMI measure, especially on the JRC collection.

        "answer": "There are three primary problems with the way the tax code treats incentive stock options. First, the tax code gives an employee a strong incentive to exercise the options early on, to achieve the tax benefit relating to the special option treatment. This means the tax code encourages young employees to write a check to their employer at a time when their entire financial life is likely to be dependent on that employer. This is the exact opposite of diversification, a key goal of personal financial management. The second issue is that the alternative minimum tax (AMT) is imposed at the time of exercise. This requires a potentially large cash outlay, at a time when the employee is unlikely to have sufficient liquidity to meet the burden. So not only does the employee have to pay his or her employer to cover the exercise premium, he or she has to send funds to the Internal Revenue Service as well. Finally, the requirement that an employee terminating employment must exercise within three months of termination date to preserve the tax advantage of the options encourages exercise at a time when the employee may not have sufficient funds, and may be looking at financial uncertainty if he or she does not yet have a new job lined up. The advantages of incentive stock options are significant, but they encourage the wrong behavior.",

        "evidence": "Semantic parsing is a task of transducing natural language to meaning representations, which in turn can be expressed through many different semantic formalisms including lambda calculus BIBREF1, DCS BIBREF2, Discourse Representation Theory (DRT) BIBREF3, AMR BIBREF4 and so on. This availability of annotated data in English has translated into the development of a plethora of models, including encoder-decoders BIBREF5, BIBREF6 as well as tree or graph-structured decoders BIBREF5, BIBREF7, BIBREF0, BIBREF8.\nWhereas the majority of semantic banks focus on English, recent effort has focussed on building multilingual representations, e.g. PMB BIBREF9, MRS BIBREF10 and FrameNetBIBREF11. However, manually annotating meaning representations in a new language is a painstaking process which explains why there are only a few datasets available for different formalisms in languages other than English. As a consequence, whereas the field has made great advances for English, little work has been done in other languages.\nWe ask: can we learn a semantic parser for English and test it where in another where annotations are not available? What would that require?\nTo answer this question, previous work have leveraged machine translation techniques to map the semantics from a language to another BIBREF12. However, these methods require parallel corpora to extract automatic alignments which are often noisy or not available at all.\nIn this paper we explore parameter-shared models instead, where a model is trained on English using language independent features and tested in a target language.\nTo show how this approach performs, we focus on the Parallel Meaning Bank BIBREF13 – a multilingual semantic bank, where sentences in English, German, Italian and Dutch have been annotated with their meaning representations. The annotations in the PMB are based on Discourse Representation Theory BIBREF3, a popular theory of meaning representation designed to account for intra and inter-sentential phenomena, like temporal expressions and anaphora. Figure 1 shows an example DRT for the sentence `I sat down and opened my laptop' in its canonical `box' representation. A DRS is a nested structure with the top part containing the discourse references and the bottom with unary and binary predicates, as well as semantic constants (e.g. `speaker'). DRS can be linked to each other via logic operator (e.g. $\\lnot $, $\\rightarrow $, $\\diamond $) or, as in this case, discourse relations (e.g. CONTINUATION, RESULT, ELABORATION, etc.).\nTo test our approach we leverage the DRT parser of liu2018discourse, an encoder-decoder architecture where the meaning representation is reconstructed in three stages, coarse-to-fine, by first building the DRS skeleton (i.e. the `box' structures) and then fill each DRS with predicates and variables. Whereas the original parser utilizes a sequential Bi-LSTM encoder with monolingual lexical features, we experiment with language-independent features in the form of cross-lingual word-embeddings, universal PoS tags and universal dependencies. In particular, we also make use of tree encoders to assess whether modelling syntax can be beneficial in cross-lingual settings, as shown for other semantic tasks (e.g. negation scope detection BIBREF14).\nResults show that language-independent features are a valid alternative to projection methods for cross-lingual semantic parsing. We show that adding dependency relation as features is beneficial, even when they are the only feature used during encoding. However, we also show that modeling the dependency structure directly via tree encoders does not outperform a sequential BiLSTM architecture for the three languages we have experimented with.\nResults show that language-independent features are a valid alternative to projection methods for cross-lingual semantic parsing.",

However, the structure of gender bias in vector space remains largely intact, and the new vectors still evince indirect bias: associations which result from gender bias between not explicitly gendered words, for example a possible association between football and business resulting from their mutual association with explicitly masculine words BIBREF4. In this paper we continue the work of BIBREF4, and show that another paradigm for gender bias mitigation proposed by BIBREF5, Counterfactual Data Augmentation (CDA), is also unable to mitigate indirect bias. We also show, using a new test we describe (non-biased gender analogies), that WED might be removing too much gender information, casting further doubt on its operationalisation of gender bias as a linear subspace.\nTo improve CDA we make two proposals.

        "evidence": "In response to concerns that volcanic ash ejected during the 2010 eruptions of Eyjafjallajökull in Iceland would damage aircraft engines, the controlled airspace of many European countries was closed to instrument flight rules traffic, resulting in what at the time was the largest air-traffic shut-down since World War II. The closures caused millions of passengers to be stranded not only in Europe, but across the world. With large parts of European airspace closed to air traffic, many more countries were affected as flights to, from, and over Europe were cancelled.\n\nAfter an initial uninterrupted shutdown over much of northern Europe from 15 to 23 April, airspace was closed intermittently in different parts of Europe in the following weeks, as the path of the ash cloud was tracked. The ash cloud caused further disruptions to air travel operations in Scotland and Ireland on 4 and 5 May and in Spain, Portugal, northern Italy, Austria, and southern Germany on 9 May. Irish and UK airspace closed again on 16 May and reopened on 17 May.\n\nThe eruption occurred beneath glacial ice. The cold water from the melting ice chilled the lava quickly, causing it to fragment into very small particles of glass (silica) and ash, which were carried into the eruption plume. The extremely fine ash particles and the large volume of steam from the glacial meltwater sent an ash plume hazardous to aircraft rapidly high into the upper atmosphere. The presence and location of the plume depended upon the state of the eruption and the winds. The large amount of glacial meltwater flowing into the eruption vent made this eruption so explosive that it ejected its ash plume directly into the jet stream, which was unusually stable and south-easterly. The ash was then carried over Europe into some of the busiest airspace in the world.\n\nThe International Air Transport Association (IATA) estimated that the airline industry worldwide would lose €148 million (US$200 million, £130 million) a day during the disruption. IATA stated that the total loss for the airline industry was around US$1.7 billion (£1.1 billion, €1.3 billion). The Airport Operators Association (AOA) estimated that airports lost £80 million over the six-and-a-half days. Over 95,000 flights had been cancelled all across Europe during the six-day airspace ban, with later figures suggesting 107,000 flights cancelled during an 8-day period, accounting for 48% of total air traffic and roughly 10 million passengers.",

        "evidence": "",
        "answer": "Nuclear magnetic resonance spectroscopy of proteins (usually abbreviated protein NMR) is a field of structural biology in which NMR spectroscopy is used to obtain information about the structure and dynamics of proteins, and also nucleic acids, and their complexes. The field was pioneered by Richard R. Ernst and Kurt Wüthrich at the ETH, and by Ad Bax, Marius Clore, Angela Gronenborn at the NIH, and Gerhard Wagner at Harvard University, among others. Structure determination by NMR spectroscopy usually consists of several phases, each using a separate set of highly specialized techniques. The sample is prepared, measurements are made, interpretive approaches are applied, and a structure is calculated and validated.\n\nNMR involves the quantum-mechanical properties of the central core (\"nucleus\") of the atom. These properties depend on the local molecular environment, and their measurement provides a map of how the atoms are linked chemically, how close they are in space, and how rapidly they move with respect to each other. These properties are fundamentally the same as those used in the more familiar magnetic resonance imaging (MRI), but the molecular applications use a somewhat different approach, appropriate to the change of scale from millimeters (of interest to radiologists) to nanometers (bonded atoms are typically a fraction of a nanometer apart), a factor of a million. This change of scale requires much higher sensitivity of detection and stability for long term measurement. In contrast to MRI, structural biology studies do not directly generate an image, but rely on complex computer calculations to generate three-dimensional molecular models.\n\nCurrently most samples are examined in a solution in water, but methods are being developed to also work with solid samples. Data collection relies on placing the sample inside a powerful magnet, sending radio frequency signals through the sample, and measuring the absorption of those signals. Depending on the environment of atoms within the protein, the nuclei of individual atoms will absorb different frequencies of radio signals. Furthermore, the absorption signals of different nuclei may be perturbed by adjacent nuclei. This information can be used to determine the distance between nuclei. These distances in turn can be used to determine the overall structure of the protein.\n\nA typical study might involve how two proteins interact with each other, possibly with a view to developing small molecules that can be used to probe the normal biology of the interaction (\"chemical biology\") or to provide possible leads for pharmaceutical use (drug development). Frequently, the interacting pair of proteins may have been identified by studies of human genetics, indicating the interaction can be disrupted by unfavorable mutations, or they may play a key role in the normal biology of a \"model\" organism like the fruit fly, yeast, the worm C. elegans, or mice. To prepare a sample, methods of molecular biology are typically used to make quantities by bacterial fermentation. This also permits changing the isotopic composition of the molecule, which is desirable because the isotopes behave differently and provide methods for identifying overlapping NMR signals.",

        "evidence": "With the steady growth in the commercial websites and social media venues, the access to users' reviews have become easier. As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nOur goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on.",

He won election to the New York State Senate in 1910 and then served as Assistant Secretary of the Navy under president Woodrow Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic Party's ticket in the 1920 United States presidential election, but Cox was defeated by Republican Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness that permanently paralyzed his legs. He returned to public office by winning the 1928 New York gubernatorial election. He served as governor of New York from 1929 to 1933, promoting programs to combat the Great Depression besetting the United States at the time. In the 1932 presidential election, Roosevelt defeated Republican incumbent president Herbert Hoover in a landslide.\n\nDuring his first 100 days as president, Roosevelt spearheaded unprecedented federal legislation and issued a profusion of executive orders that instituted the New Deal. He created numerous programs to provide relief to the unemployed and farmers while seeking economic recovery with the National Recovery Administration and other programs. He also instituted major regulatory reforms related to finance, communications, and labor, and presided over the end of Prohibition. In 1936, Roosevelt won a landslide reelection with the economy having improved rapidly from 1933, but the economy relapsed into a deep recession in 1937 and 1938. Later, Roosevelt unsuccessfully sought passage of the Judicial Procedures Reform Bill of 1937. The conservative coalition formed in 1937 to block the implementation of further New Deal programs and reforms. He ran successfully for reelection in 1940, becoming the only American president to serve for more than two terms.\n\nWith World War II looming after 1938 in addition to the Japanese invasion of China and the aggression of Nazi Germany, Roosevelt gave strong diplomatic and financial support to China as well as the United Kingdom and the Soviet Union while the United States remained officially neutral. Following the Japanese attack on Pearl Harbor on December 7, 1941, he obtained a declaration of war on Japan the next day, and a few days later, on Germany and Italy. He worked closely with other national leaders in leading the Allies against the Axis powers. Roosevelt supervised the mobilization of the American economy to support the war effort and implemented a Europe first strategy. He also initiated the development of the world's first atomic bomb and worked with the other Allied leaders to lay the groundwork for the United Nations and other post-war institutions. He won reelection in 1944 but with his physical health seriously and steadily declining during the war years, he died in 1945. Since his death, several of Roosevelt's actions have come under substantial criticism, such as his ordering of the incarceration of Japanese Americans in concentration camps.

        "question": "What kind of methods do they use to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample?",
        "answer": "Deep reinforcement learning methods.",
        "evidence": "The goal of Machine Reading Comprehension (MRC) is to have machines read a text passage and then generate an answer (or select an answer from a list of given candidates) for any question about the passage. There has been a growing interest in the research community in exploring neural MRC models in an end-to-end fashion, thanks to the availability of large-scale datasets, such as CNN/DM BIBREF0 and SQuAD BIBREF1 .\nDespite the variation in model structures, most state-of-the-art models perform reading comprehension in two stages. First, the symbolic representations of passages and questions are mapped into vectors in a neural space. This is commonly achieved via embedding and attention BIBREF2 , BIBREF3 or fusion BIBREF4 . Then, reasoning is performed on the vectors to generate the right answer.\nIdeally, the best attention and reasoning strategies should adapt organically in order to answer different questions. However, most MRC models use a static attention and reasoning strategy indiscriminately, regardless of various question types. One hypothesis is because these models are optimized on those datasets whose passages and questions are domain-specific (or of a single type). For example, in CNN/DM, all the passages are news articles, and the answer to each question is an entity in the passage. In SQuAD, the passages came from Wikipedia articles and the answer to each question is a text span in the article. Such a fixed-strategy MRC model does not adapt well to other datasets. For example, the exact-match score of BiDAF BIBREF2 , one of the best models on SQuAD, drops from 81.5 to 55.8 when applied to TriviaQA BIBREF5 , whereas human performance is 82.3 and 79.7 on SQuAD and TriviaQA, respectively.\nIn real-world MRC tasks, we must deal with questions and passages of different types and complexities, which calls for models that can dynamically determine what attention and reasoning strategy to use for any input question-passage pair on the fly. In a recent paper, BIBREF6 proposed dynamic multi-step reasoning, where the number of reasoning steps is determined spontaneously (using reinforcement learning) based on the complexity of the input question and passage. With a similar intuition, in this paper we propose a novel MRC model which is dynamic not only on the number of reasoning steps it takes, but also on the way it performs attention. To the best of our knowledge, this is the first MRC model with this dual-dynamic capability.\nThe proposed model is called a Dynamic Fusion Network (DFN). In this paper, we describe the version of DFN developed on the RACE dataset BIBREF7 . In RACE, a list of candidate answers is provided for each passage-question pair. So DFN for RACE is a scoring model - the answer candidate with the highest score will be selected as the final answer.\nLike other MRC models, DFNs also perform machine reading in two stages: attention and reasoning. DFN is unique in its use of a dynamic multi-strategy attention process in the attention stage. Here “attention” refers to the process that texts from different sources (passage, question, answers) are combined in the network. In literature, a fixed attention mechanism is usually employed in MRC models. In DFN, the attention strategy is not static; instead, the actual strategy for drawing attention among the three text sources are chosen on the fly for each sample. This lends flexibility to adapt to various question types that require different comprehension skills. The output of the attention stage is then fed into the reasoning module to generate the answer score. The reasoning module in DFN uses dynamic multi-step reasoning, where the number of steps depends on the complexity of the question-passage pair and varies from sample to sample.\nInspired by ReasoNet BIBREF6 and dynamic neural module networks BIBREF8 , we use deep reinforcement learning methods BIBREF9 , BIBREF10 to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample. We use RL in favor of other simpler methods (like cascading, pooling or weighted averaging) mainly because we intend to learn a policy that constructs an instance of DFN of a sample-specific structure. Given an input sample consisting of a question, a passage and a list of candidate answers in RACE, an instance of DFN can be constructed via RL step by step on the fly. Such a policy is particularly appealing as it also provides insights on how the model performs on different types of questions. At each decision step, the policy maps its “state”, which represents an input sample, and DFN's partial knowledge of the right answer, to the action of assembling proper attention and reasoning modules for DFN.\nExperiments conducted on the RACE dataset show that DFN significantly outperforms previous state-of-the-art MRC models and has achieved the best result reported on RACE. A thorough empirical analysis also demonstrates that DFN is highly effective in understanding passages of a wide variety of styles and answering questions of different complexities.\nInspired by ReasoNet and dynamic neural module networks, we use deep reinforcement learning methods to dynamically choose the optimal attention strategy and the optimal number of reasoning steps for a given sample.",

        "evidence": "The Build Back Better Plan or Build Back Better agenda was a legislative framework proposed by U.S. president Joe Biden between 2020 and 2021. Generally viewed as ambitious in size and scope, it sought the largest nationwide public investment in social, infrastructural, and environmental programs since the 1930s Great Depression-era policies of the New Deal.\n\nThe Build Back Better plan was divided into three parts:\n\nAmerican Rescue Plan (ARP), a COVID-19 pandemic-relief bill;\nAmerican Jobs Plan (AJP), a proposal to address long-neglected infrastructure needs and reduce America's contributions to destructive effects of climate change; and\nAmerican Families Plan (AFP), a proposal to fund a variety of social policy initiatives, some of which (e.g., paid family leave) had never before been enacted nationally in the U.S.\nThe first part was passed as the $1.9 trillion American Rescue Plan Act of 2021, and was signed into law in March 2021. The other two parts were reworked into different bills over the course of extensive negotiations. Aspects of the AJP's infrastructure goals were diverted into the Infrastructure Investment and Jobs Act, which was signed into law in November 2021. Other AJP priorities (e.g., climate change remediation, home health care reform, etc.) were then merged with the AFP to form the Build Back Better Act. The bill passed the Democratic-controlled House of Representatives but struggled to gain the support of Democrats Joe Manchin of West Virginia and Kyrsten Sinema of Arizona in the evenly divided Senate, with unified Republican opposition. Manchin and Sinema negotiated the reduction of Build Back Better Act's size, scope, and cost significantly with Biden and Democratic congressional leaders, but Manchin, widely viewed as the key swing vote needed to pass the bill in the Senate, ultimately rejected it over the procedural tactics used. Continued negotiations between Manchin and Senate Majority Leader Chuck Schumer eventually resulted in the Inflation Reduction Act of 2022, which was signed into law in August 2022, and incorporated some of the Build Back Better Act's climate change, healthcare, and tax reform proposals while excluding its social safety net proposals.",

        "answer": "Fractional-reserve banking is the system of banking operating in almost all countries worldwide, under which banks that take deposits from the public are required to hold a proportion of their deposit liabilities in liquid assets as a reserve, and are at liberty to lend the remainder to borrowers. Bank reserves are held as cash in the bank or as balances in the bank's account at the central bank. The country's central bank determines the minimum amount that banks must hold in liquid assets, called the \"reserve requirement\" or \"reserve ratio\". Most commercial banks hold more than this minimum amount as excess reserves.\n\nBank deposits are usually of a relatively short-term duration, and may be \"at call\", while loans made by banks tend to be longer-term, resulting in a risk that customers may at any time collectively wish to withdraw cash out of their accounts in excess of the bank reserves. The reserves only provide liquidity to cover withdrawals within the normal pattern. Banks and the central bank expect that in normal circumstances only a proportion of deposits will be withdrawn at the same time, and that reserves will be sufficient to meet the demand for cash. However, banks may find themselves in a shortfall situation when depositors wish to withdraw more funds than the reserves held by the bank. In that event, the bank experiencing the liquidity shortfall may borrow short-term funds in the interbank lending market from banks with a surplus. In exceptional situations, such as during an unexpected bank run, the central bank may provide funds to cover the short-term shortfall as lender of last resort.",

        "evidence": "\nWith the wealth of information being posted online daily, Relation Extraction (RE) has become increasingly important. RE aims specifically to extract relations from raw sentences and represent them as succinct relation tuples of the form (head, relation, tail). An example is (Barack Obama, spouse, Michelle Obama).\nThe concise representations provided by RE models have been used to extend Knowledge Bases (KBs) BIBREF0, BIBREF1. These KBs are then used heavily in NLP systems, such as Task-Based Dialogue Systems. In recent years, much focus in the NRE community has been centered on improvements in model precision and the reduction of noise BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6. Yet, little attention has been devoted towards the fairness of such systems.\nIn this paper, we take the first step at understanding and evaluating gender bias in NRE systems. We analyze gender bias by measuring the differences in model performance when extracting relations from sentences written about females versus sentences written about males. Significant discrepancies in performance between genders could diminish the fairness of systems and distort outcomes in applications that use them. For example, if a model predicts the occupation relation for with higher recall for male entities, this could lead to KBs having more occupation information for males. Downstream search tasks using that KB could produce biased predictions, such as ranking articles about female computer scientists below articles about their male peers.\nWe provide the first evaluation of social bias in NRE models; specifically, we evaluate gender bias in English language predictions of a collection of popularly used and open source NRE models BIBREF2, BIBREF4, BIBREF3, BIBREF5. We evaluate OpenNRE on two fronts: (1) examining Equality of Opportunity BIBREF7 when OpenNRE is trained on an unmodified dataset and (2) examining the effect that various debiasing options BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12 have on both absolute F1 score and the difference in F1-scores on male and female datapoints.\nHowever, carrying out such an evaluation is difficult with existing NRE datasets, such as the NYT dataset from BIBREF13, because there is no reliable way to obtain gender information about the entities. Thus, we create a new dataset specifically aimed at evaluating gender bias for NRE, just as prior work has done for other tasks like Coreference Resolution BIBREF14, BIBREF9. We call our dataset WikiGenderBias and make it publicly available. Our contributions are as such:\nWikiGenderBias is the first dataset aimed at training and evaluating NRE systems for gender bias.

The leaves of seedling philodendrons are usually heart-shaped early in the life of the plant. But after it has matured past the seedling stage, the leaves will acquire the typical juvenile leaf's shape and size. Later in the philodendron's life, it starts producing adult leaves, a process called metamorphosis. Most philodendrons go through metamorphosis gradually; there is no immediately distinct difference between juvenile and adult leaves. Aside from being typically much bigger than the juvenile leaves, the shape of adult leaves can be significantly different.

Five batches of 100 questions each were released every two weeks. Participating systems have 24 hours to submit their results. At the time of writing, all batches had been released.\nThe questions are categorized into different question types: factoid, list, summary and yes/no. Our work concentrates on answering factoid and list questions. For factoid questions, the system's responses are interpreted as a ranked list of answer candidates. They are evaluated using mean-reciprocal rank (MRR). For list questions, the system's responses are interpreted as a set of answers to the list question. Precision and recall are computed by comparing the given answers to the gold-standard answers. F1 score, i.e., the harmonic mean of precision and recall, is used as the official evaluation measure .\nMost existing biomedical QA systems employ a traditional QA pipeline, similar in structure to the baseline system by weissenborn2013answering. They consist of several discrete steps, e.g., named-entity recognition, question classification, and candidate answer scoring. These systems require a large amount of resources and feature engineering that is specific to the biomedical domain.

        "question": "What is the relevant information of embedded items?",
        "answer": "It is including but not limited to geographic information, ratings, and attributes.",
        "evidence": "Learning semantic representations (embeddings) of different entities, such as textual, commercial, and physical, has been a recent and active area of research. Such representations can facilitate applications that rely on a notion of similarity, for example recommendation systems and ranking algorithms in e-commerce.\nIn natural language processing, word2vec BIBREF0 learns vector representations of words from large quantities of text, where each word is mapped to a $d$-dimensional vector such that semantically similar words have geometrically closer vectors. This is achieved by predicting either the context words appearing in a window around a given target word (skip-gram model), or the target word given the context (CBOW model). The main assumption is that words appearing frequently in similar contexts share statistical properties (the distributional hypothesis). Crucially, word2vec models, like many other word embedding models, preserve sequential information encoded in text so as to leverage word co-occurrence statistics. The skip-gram model has been adapted to other domains in order to learn dense representations of items other than words. For example, product embeddings in e-commerce BIBREF1 or vacation rental embeddings in the hospitality domain BIBREF2 can be learned by treating purchase histories or user click sequences as sentences and applying a word2vec approach.\nMost of the prior work on item embedding exploit the co-occurrence of items in a sequence as the main signal for learning the representation. One disadvantage of this approach is that it fails to incorporate rich structured information associated with the embedded items. For example, in the travel domain, where we seek to embed hotels and other travel-related entities, it could be helpful to encode explicit information such as user ratings, star ratings, hotel amenities, and location in addition to implicit information encoded in the click-stream.\nIn this work, we propose an algorithm for learning hotel embeddings that combines sequential user click information in a word2vec approach with additional structured information about hotels. We propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes. In experimental results, we show that enhancing the neural network to jointly encode click and supplemental structured information outperforms a skip-gram model that encodes the click information alone. The proposed architecture also naturally handles the cold-start problem for hotels with little or no historical clicks. Specifically, we can infer an embedding for these properties by leveraging their supplemental structured metadata.\nCompared to previous work on item embeddings, the novel contributions of this paper are as follows:\nWe propose a novel framework for fusing multiple sources of information about an item (such as user click sequences and item-specific information) to learn item embeddings via self-supervised learning.\nWe generate an interpretable embedding which can be decomposed into sub-embeddings for clicks, location, ratings, and attributes, and employed either as separate component embeddings or a single, unified embedding.\nIt is also dynamic, meaning it is easy to reflect future changes in attributes such as star-rating or addition of amenities in the embedding vectors without retraining.\nWe address the cold-start problem by including hotel metadata which are independent of user click-stream interactions and available for all hotels. This helps us to better impute embeddings for sparse items/hotels.\nWe show significant gains over previous work based on click-embedding in several experimental studies.\nThe structure of the remainder of this paper is as follows. Section 2 gives an overview of some of the recent works on neural embedding. Section 3 provides details of the proposed framework, including the neural network architecture, training methodology, and how the cold-start problem is addressed. In Section 4, we present experimental results on several different tasks and a comparison with previous state-of-the-art work. Section 5 concludes the paper.\nWe propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes.",

Note that they also have a linear layer or MLP after message-passing between nodes. Instead of using an additional linear layer, GNP concatenates the outputs of GNP+ and GNP− and passes them to the linear layer or MLP. Also, note that we set the dimensions so that the concatenated output of GNP has the same dimension as the output of other GNNs. These facts are clarified in the revised paper.",
        "evidence": "The GNP function in equation 3.1 is not continuous and even not defined at p = 0. Hence, directly learning GNP in the original form as in equation 3.1 (even with p = 0 ignored) can cause instability, especially when an algorithm is trying to move from a positive p value to a negative p value. Instead, we suggest splitting the GNP function into two parts, GNP + with positive p and GNP − with negative p, and let the model choose the right balance between them. Specifically, define\nwhere p + > 0, q + , p − > 0, and q − are learnable parameters. Given a set of node features V, we first split the feature dimension into two, and compute the output from GNP + for the first half and from GNP − for the second half. Then we mix two outputs with a single linear layer to get the final output.\nwhere • is the floor function, W ∈ R d×d and b ∈ R d are learnable parameters. Note that widelyused GNN layers have a linear layer or MLP after message-passing between nodes. Instead of using an additional linear layer, GNP concatenates the outputs of GNP + and GNP − and passes them to the linear layer or MLP. Therefore, we have only four extra parameters (p + , p − , q + and q − ) for each GNN layer of typical GNN architectures. With this design, GNP can easily switch between positive p and negative p, choosing proper values according to tasks.\nMany real-world data, such as relationships between people in social networks or chemical bonds between atoms, can naturally be represented as graphs. Finding models with proper inductive biases to better describe such graph data has been a common goal for many researchers, and Graph Neural Networks (GNNs) are considered to be the most successful model. They have proved effective for a variety of tasks, including recommendation, drug discovery, and chip design.\nAn important design choice for a GNN often overlooked is the specification of pooling functions, the functions used for the aggregation or readout operation in GNNs. They are usually required to be invariant w.r.t. the permutation of nodes in a graph, and common choices are element-wise summation (sum), maximum (max), minimum (min), or average (mean). Some recent works also proposed to use parametric models and learn them from data as well.\nWhile most of the previous works on this line focused on improving predictive performance for their own tasks, recently, studied the impact of the choice of pooling functions on the ability of a neural network to extrapolate. Specifically, highlighted the importance of the choice of pooling functions in order to make GNNs generalize over the data lying outside of the support of the training data distribution, and they argued that the specification of the pooling functions acts as an important inductive bias that can make GNNs either completely fail to extrapolate or gracefully generalize to out-of-distribution data. As a motivating example, consider the problem of counting the number of nodes in a graph. If we are to solve this problem with a single-layer GNN having one readout layer, probably the best pooling function would be sum, and the corresponding model will readily generalize to graphs with a much larger number of nodes than the ones seen during training. On the other hand, if we choose the pooling function as max instead, it may still fit the training data well but completely fail to predict the number of nodes in out-of-distribution graphs.\nThe findings in raise a natural question; which pooling functions should be used for a given problem in order to make GNNs constructed with them successfully extrapolate for out-of-distribution data? did not present any guide but empirically showed that we do have the \"right\" pooling function for each problem tested, and when a pooling function is not properly selected, GNNs completely fails to extrapolate. The caveat here is that we do not know which pooling function is the right choice before actually training and validating the model.\nTo this end, in this paper, we present a generic learning-based method to find proper pooling functions for a given arbitrary problem. Our method, entitled Generalized Norm-based Pooling (GNP), formulates the pooling functions as a generic L p norm-like function (including negative p as well), and learns the parameters inside the pooling functions in an end-to-end fashion. Unlike previous learning-based pooling methods that are usually tailored for specific tasks or focused on improving predictive performances, GNP can be applied to arbitrary tasks, and it improves the extrapolation ability of GNNs constructed with it. Also, GNP includes most of the pooling functions being used for GNNs as special cases. Despite the enhanced flexibility, GNP incurs minimal overhead in GNN in terms of the model complexity. A naïve application of GNP to GNNs is likely to fail because of some difficulty in training, so we propose a simple remedy to this. Using nine graph-level, node-level, and set-related tasks, we demonstrate that GNNs with GNP trained by our training scheme extrapolate for out-of-distribution data comparably and sometimes even better than those with pooling functions that are carefully chosen among of widely-used ones. In addition, we demonstrate the effectiveness of GNP on four real-world tasks (graph classification, influence maximization, node classification, and graph regression) using six additional GNN architectures, GAT, PNA, hierarchical SAGPool, ASAPool, and MONSTOR) and eight real-world graphs. We summarize our contributions as follows:\n• Generalized pooling function: We propose GNP, a simple yet flexible pooling function that can readily be applied to arbitrary tasks involving GNNs, with minimal parameter overhead. • Effective training methods: We propose effective training methods for GNP.\n• Extensive experiments: We empirically demonstrate that GNNs with GNP generalize to out-ofdistribution data on nine extrapolation tasks. We also show successful application of GNP to six GNN architectures on four real-world tasks in eight real-world graphs with up to one million edges.\nInstead of using an additional linear layer, GNP concatenates the outputs of GNP+ and GNP− and passes them to the linear layer or MLP. Therefore, we have only four extra parameters (p +, p −, q + and q −) for each GNN layer of typical GNN architectures.****In addition, we demonstrate the effectiveness of GNP on four real-world tasks (graph classification, influence maximization, node classification, and graph regression) using six additional GNN architectures (GCN (Kipf & Welling, 2017), GAT (Velickovic et al., 2018), PNA (Corso et al., 2020), hierarchical SAGPool (Lee et al., 2019b), ASAPool (Ranjan et al., 2020), and MONSTOR (Ko et al., 2020)) and eight real-world graphs.",

        "question": "What does the best system for Dutch shows？",
        "answer": "It provides a considerable performance increase over the unoptimised word n-gram baseline system.",
        "evidence": "In this section, we present the results of our experiments on the automatic detection of cyberbullying-related posts in an English (EN) and Dutch (NL) corpus of ASKfm posts. Ten-fold cross-validation was performed in exhaustive grid-search over different feature type and hyperparameter combinations (see Section SECREF4 ). The unoptimised word INLINEFORM0 -gram-based classifier and keyword-matching system serve as baselines for comparison. Precision, Recall and F INLINEFORM1 performance metrics were calculated on the positive class (i.e., `binary averaging'). We also report Area Under the ROC curve (AUC) scores, a performance metric that is more robust to data imbalance than precision, recall and micro-averaged F-score BIBREF74 .\nTable TABREF45 gives us an indication of which feature type combinations score best and hence contribute most to this task. A total of 31 feature type combinations, each with 28 different hyperparameter sets have been tested. Table TABREF45 shows the results for the three best scoring systems by included feature types with optimised hyperparameters. The maximum attained F INLINEFORM0 -score in cross-validation is 64.26% for English and 61.20% for Dutch and shows that the classifier benefits from a variety of feature types. The results on the holdout test set show that the trained systems generalise well on unseen data, indicating little under- or overfitting. The simple keyword-matching baseline system has the lowest performance for both languages even though it obtains high recall for English, suggesting that profane language characterises many cyberbullying-related posts. Feature group and hyperparameter optimisation provides a considerable performance increase over the unoptimised word INLINEFORM1 -gram baseline system. The top-scoring systems for each language do not differ a lot in performance, except the best system for Dutch, which trades recall for precision when compared to the runner-ups.\nTable TABREF47 presents the scores of the (hyperparameter-optimised) single feature type systems, to gain insight into the performance of these feature types when used individually. Analysis of the combined and single feature type sets reveals that word INLINEFORM0 -grams, character INLINEFORM1 -grams, and subjectivity lexicons prove to be strong features for this task. In effect, adding character INLINEFORM2 -grams always improved classification performance for both languages. They likely provide robustness to lexical variation in social media text, as compared to word INLINEFORM3 -grams. While subjectivity lexicons appear to be discriminative features, term lists perform badly on their own as well as in combinations for both languages. This shows once again (cf. profanity baseline) that cyberbullying detection requires more sophisticated information sources than profanity lists. Topic models seem to do badly for both languages on their own, but in combination, they improve Dutch performance consistently. A possible explanation for their varying performance in both languages would be that the topic models trained on the Dutch background corpus are of better quality than the English ones. In effect, a random selection of background corpus texts reveals that the English scrape contains more noisy data (i.e., low word-count posts and non-English posts) than the Dutch data.\nA shallow qualitative analysis of the classification output provided insight into some of the classification mistakes.\nTable TABREF52 gives an overview of the error rates per cyberbullying category of the best performing and baseline systems. This could give an indication of which types of bullying the current system has trouble classifying. All categories are always considered positive for cyberbullying (i.e., the error rate equals the false negative rate), except for Sexual and Insult which can also be negative (in case of harmless sexual talk and `socially acceptable' insulting language like `hi bitches, in for a movie?' the corresponding category was indicated, but the post itself was not annotated as cyberbullying) and Not cyberbullying, which is always negative. Error rates often being lowest for the profanity baseline confirms that it performs particularly well in terms of recall (at the expense of precision, see Table TABREF47 ) When looking at the best system for both languages, we see that Defense is the hardest category to correctly classify. This should not be a surprise as the category comprises defensive posts from bystanders and victims, which contain less aggressive language than cyberbullying attacks and are often shorter in length than the latter. Assertive defensive posts (i.e., a subcategory of Defense) that attack the bully) are, however, more often correctly classified. There are not enough instances of Encouragement for either language in the holdout to be representative. In both languages, threats, curses and incidences of sexual harassment are most easily recognisable, showing (far) lower error rates than the categories Defamation, Defense, Encouragements to the harasser, and Insult.\nQualitative error analysis of the English and Dutch predictions reveals that false positives often contain aggressive language directed at a second person, often denoting personal flaws or containing sexual and profanity words. We see that misclassifications are often short posts containing just a few words and that false negatives often lack explicit verbal signs of cyberbullying (e.g. insulting or profane words) or are ironic (examples 2 and 3). Additionally, we see that cyberbullying posts containing misspellings or grammatical errors and incomplete words are also hard to recognise as such (examples 4 and 5). The Dutch and English data are overall similar with respect to qualitative properties of classification errors.\nIn short, the experiments show that our classifier clearly outperforms both a keyword-based and word INLINEFORM0 -gram baseline. However, analysis of the classifier output reveals that false negatives often lack explicit clues that cyberbullying is going on, indicating that our system might benefit from irony recognition and integrating world knowledge to capture such implicit realisations of cyberbullying.\nGiven that we present the first elaborate research on detecting signals of cyberbullying regardless of the author role instead of bully posts alone, crude comparison with the state of the art would be irrelevant. We observe, however, that our classifier obtains competitive results compared to BIBREF32 , BIBREF33 , BIBREF35 , BIBREF34 , BIBREF37 .\nThe top-scoring systems for each language do not differ a lot in performance, except the best system for Dutch, which trades recall for precision when compared to the runner-ups.",

        "question": "Given the following text, what is special about Prime Numbers?",
        "evidence": "A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order.\n\nThe property of being prime is called primality. A simple but slow method of checking the primality of a given number \n�\nn, called trial division, tests whether \n�\nn is a multiple of any integer between 2 and \n�\n{\\sqrt {n}}. Faster algorithms include the Miller–Rabin primality test, which is fast but has a small chance of error, and the AKS primality test, which always produces the correct answer in polynomial time but is too slow to be practical. Particularly fast methods are available for numbers of special forms, such as Mersenne numbers. As of December 2018 the largest known prime number is a Mersenne prime with 24,862,048 decimal digits.\n\nThere are infinitely many primes, as demonstrated by Euclid around 300 BC. No known simple formula separates prime numbers from composite numbers. However, the distribution of primes within the natural numbers in the large can be statistically modelled. The first result in that direction is the prime number theorem, proven at the end of the 19th century, which says that the probability of a randomly chosen large number being prime is inversely proportional to its number of digits, that is, to its logarithm.\n\nSeveral historical questions regarding prime numbers are still unsolved. These include Goldbach's conjecture, that every even integer greater than 2 can be expressed as the sum of two primes, and the twin prime conjecture, that there are infinitely many pairs of primes having just one even number between them. Such questions spurred the development of various branches of number theory, focusing on analytic or algebraic aspects of numbers. Primes are used in several routines in information technology, such as public-key cryptography, which relies on the difficulty of factoring large numbers into their prime factors. In abstract algebra, objects that behave in a generalized way like prime numbers include prime elements and prime ideals.",

        "evidence": "Story-telling is on the frontier of current text generation technology: stories must remain thematically consistent across the complete document, requiring modeling very long range dependencies; stories require creativity; and stories need a high level plot, necessitating planning ahead rather than word-by-word generation BIBREF0 .\nWe tackle the challenges of story-telling with a hierarchical model, which first generates a sentence called the prompt describing the topic for the story, and then conditions on this prompt when generating the story. Conditioning on the prompt or premise makes it easier to generate consistent stories because they provide grounding for the overall plot. It also reduces the tendency of standard sequence models to drift off topic.\nWe find that standard sequence-to-sequence (seq2seq) models BIBREF1 applied to hierarchical story generation are prone to degenerating into language models that pay little attention to the writing prompt (a problem that has been noted in other domains, such as dialogue response generation BIBREF2 ). This failure is due to the complex and underspecified dependencies between the prompt and the story, which are much harder to model than the closer dependencies required for language modeling (for example, consider the subtle relationship between the first sentence and prompt in Figure FIGREF1 ).\nTo improve the relevance of the generated story to its prompt, we introduce a fusion mechanism BIBREF3 where our model is trained on top of an pre-trained seq2seq model. To improve over the pre-trained model, the second model must focus on the link between the prompt and the story. For the first time, we show that fusion mechanisms can help seq2seq models build dependencies between their input and output.\nAnother major challenge in story generation is the inefficiency of modeling long documents with standard recurrent architectures—stories contain 734 words on average in our dataset. We improve efficiency using a convolutional architecture, allowing whole stories to be encoded in parallel. Existing convolutional architectures only encode a bounded amount of context BIBREF4 , so we introduce a novel gated self-attention mechanism that allows the model to condition on its previous outputs at different time-scales.\nTo train our models, we gathered a large dataset of 303,358 human generated stories paired with writing prompts from an online forum. Evaluating free form text is challenging, so we also introduce new evaluation metrics which isolate different aspects of story generation.\nExperiments show that our fusion and self-attention mechanisms improve over existing techniques on both automated and human evaluation measures. Our new dataset and neural architectures allow for models which can creatively generate longer, more consistent and more fluent passages of text. Human judges prefer our hierarchical model's stories twice as often as those of a non-hierarchical baseline.\nExisting convolutional architectures only encode a bounded amount of context, so we introduce a novel gated self-attention mechanism that allows the model to condition on its previous outputs at different time-scales.",

        "evidence": "The regulation of gene expression by environmental factors and during different stages of development can occur at each step of the process such as transcription, RNA splicing, translation, and post-translational modification of a protein. Gene expression can be influenced by positive or negative regulation, depending on which of the two types of regulatory proteins called transcription factors bind to the DNA sequence close to or at a promoter. A cluster of genes that share the same promoter is called an operon, found mainly in prokaryotes and some lower eukaryotes (e.g., Caenorhabditis elegans). In positive regulation of gene expression, the activator is the transcription factor that stimulates transcription when it binds to the sequence near or at the promoter. Negative regulation occurs when another transcription factor called a repressor binds to a DNA sequence called an operator, which is part of an operon, to prevent transcription. Repressors can be inhibited by compounds called inducers (e.g., allolactose), thereby allowing transcription to occur. Specific genes that can be activated by inducers are called inducible genes, in contrast to constitutive genes that are almost constantly active. In contrast to both, structural genes encode proteins that are not involved in gene regulation. In addition to regulatory events involving the promoter, gene expression can also be regulated by epigenetic changes to chromatin, which is a complex of DNA and protein found in eukaryotic cells.",

We further show that the EED transformation fits in the classical framework of MLE of intrinsic dimension, effectively altering the intrinsic dimension thereby realizing low-dimensional mapping.\nWe argue that all successful DR methods, including among others t-SNE and UMAP, make use of the rationale of space expansion to enable data visualization in a space of drastically reduced dimension.

SpaceMAP is generic and has a limited number of hyperparameters, with the most important ones related to the selection of number of nearest neighbors in the near field and middle field.

Our experiments on a diverse range of datasets demonstrated its excellent performance in comparison with other state-of-the-art DR methods.

Much of his work is focused on the visual system, including the mechanisms controlling light-mediated activation of the circadian and autonomic arousal centers in the brain, as well as brain control over conscious vision or sight.[better source needed] Huberman has been credited with coining the term \"Non-Sleep Deep Rest\" (NSDR), which he earlier referred to as Yog Nindra, which is to practices that place the brain and body into shallow sleep to accelerate neuroplasticity and help offset mental and physical fatigue.[better source needed]\n\nGraduate and postdoctoral research\nFrom 1998 to 2000, Huberman worked in the laboratory of Irving Zucker, as well as working with Marc Breedlove, at University of California, Berkeley, as part of a team that defined how early androgen exposure impacts development, and he performed the first experiments defining the structure of binocular visual pathways that set the circadian clock in the hypothalamus. From 2000 to 2004, working as a PhD student in the laboratory of Barbara Chapman at the Center for Neuroscience at the University of California, Davis, Huberman discovered that neural activity and axon guidance molecules work in concert to ensure proper wiring of binocular maps in the brain. Huberman was a Helen Hay Whitney postdoctoral fellow researcher in the laboratory of Ben A. Barres from 2005 to 2010.\n\nHuberman was an assistant professor of neurobiology and neuroscience at University of California, San Diego, from 2011 to 2015. His lab pioneered using genetic tools to study the visual system function, development and disease. Among the Huberman Lab's discoveries was the finding that specific types of retinal neurons degenerate early in glaucoma a common blinding disease depleting sight in over 70 million people, for which there is no cure.\n\nAfter moving to Stanford in 2016, Huberman discovered and published the use of non-invasive methods such as visual stimulation to enhance regeneration of damaged retinal neurons, leading to partial recovery from blindness, especially when the stimulation is paired with specific forms of gene therapy. The work was covered extensively in the popular press, including Time magazine and Scientific American and is part of the National Eye Institute's Audacious Goals Initiative to restore vision to the blind[citation needed]. The Huberman Lab extended those findings to develop a human clinical trial using virtual reality technology to stimulate regeneration and plasticity of damaged retinal and other visual system neurons.\n\nIn 2017, the Huberman Lab created a virtual reality platform for probing the neural mechanisms underlying pathological fear and anxiety. That work involved collecting 360-degree video of various fear-inducing scenarios such as heights and claustrophobia as well as atypical fear-inducing situations such as swimming with great white sharks. The Huberman VR platform is aimed at making discoveries that will lead to developing new tools for humans to adjust their state in order to promote adaptive coping with stress. The first installment of that work was published in Current Biology, in 2021 as a collaboration with neurosurgeon and neuroscientist Edward Chang (UCSF), wherein they reported that specific patterns of insular cortex brain activity correlate with and may predict anxiety responses.\n\nIn May, 2018, Huberman Laboratory published an article in the journal Nature reporting its discovery of two new mammalian brain circuits: one that promotes fear and paralysis, and another that promotes \"courageous\"/confrontational reaction, to visually-evoked threats. That discovery prompted the now ongoing exploration of how these brain regions may be involved in humans suffering from anxiety-related disorders such as phobias and generalized anxiety.\n\nIn 2020, Huberman initiated a collaboration with the laboratory of David Spiegel in the Stanford Department of Psychiatry and Behavioral Sciences, to systematically study how particular patterns of respiration (i.e., breathing/breathwork) and the visual system influence the autonomic nervous system, stress, and other brain states, including sleep.\n\nIn 2021, Huberman launched the \"Huberman Lab\" podcast with the goal of translating neuroscience into tools that can be applied in everyday life. It is a top podcast on Apple Podcasts and Spotify. He was originally inspired to start the podcast after his appearance on the Lex Fridman Podcast.

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nInitial works for attacking text models relied on introducing errors at the character level (Ebrahimi et al., 2018; Gao et al., 2018) or adding and deleting words (Li et al., 2016; Liang et al., 2017; Feng et al., 2018) for creating adversarial examples.",

It was supposed that if expressions from the same similarity set co-occur in the same document then their contribution into the document's topics is really more than it is presented with their frequencies, therefore their frequencies should be increased. In such an approach, the algorithm can \"see\" similarities between different multiword expressions with the same component word.\nIn our approach, at first, we include related single words and phrases from a thesaurus such as WordNet or EuroVoc in these similarity sets. Then, we add preliminarily extracted ngrams into these sets and, this way, we use two different sources of external knowledge. We use the same LDA-SIM algorithm as described in BIBREF16 but study what types of semantic relations can be introduced into such similarity sets and be useful for improving topic models.

        "evidence": "In the field of natural language processing (NLP), the most prevalent neural approach to obtaining sentence representations is to use recurrent neural networks (RNNs), where words in a sentence are processed in a sequential and recurrent manner. Along with their intuitive design, RNNs have shown outstanding performance across various NLP tasks e.g. language modeling BIBREF0 , BIBREF1 , machine translation BIBREF2 , BIBREF3 , BIBREF4 , text classification BIBREF5 , BIBREF6 , and parsing BIBREF7 , BIBREF8 .\nAmong several variants of the original RNN BIBREF9 , gated recurrent architectures such as long short-term memory (LSTM) BIBREF10 and gated recurrent unit (GRU) BIBREF2 have been accepted as de-facto standard choices for RNNs due to their capability of addressing the vanishing and exploding gradient problem and considering long-term dependencies. Gated RNNs achieve these properties by introducing additional gating units that learn to control the amount of information to be transferred or forgotten BIBREF11 , and are proven to work well without relying on complex optimization algorithms or careful initialization BIBREF12 .\nMeanwhile, the common practice for further enhancing the expressiveness of RNNs is to stack multiple RNN layers, each of which has distinct parameter sets (stacked RNN) BIBREF13 , BIBREF14 . In stacked RNNs, the hidden states of a layer are fed as input to the subsequent layer, and they are shown to work well due to increased depth BIBREF15 or their ability to capture hierarchical time series BIBREF16 which are inherent to the nature of the problem being modeled.\nHowever this setting of stacking RNNs might hinder the possibility of more sophisticated recurrence-based structures since the information from lower layers is simply treated as input to the next layer, rather than as another class of state that participates in core RNN computations. Especially for gated RNNs such as LSTMs and GRUs, this means that layer-to-layer connections cannot fully benefit from the carefully constructed gating mechanism used in temporal transitions. Some recent work on stacking RNNs suggests alternative methods that encourage direct and effective interaction between RNN layers by adding residual connections BIBREF17 , BIBREF18 , by shortcut connections BIBREF18 , BIBREF19 , or by using cell states of LSTMs BIBREF20 , BIBREF21 .\nIn this paper, we propose a method of constructing multi-layer LSTMs where cell states are used in controlling the vertical information flow. This system utilizes states from the left and the lower context equally in computation of the new state, thus the information from lower layers is elaborately filtered and reflected through a soft gating mechanism. Our method is easy-to-implement, effective, and can replace conventional stacked LSTMs without much modification of the overall architecture.\nWe call the proposed architecture Cell-aware Stacked LSTM, or CAS-LSTM, and evaluate our method on multiple benchmark datasets: SNLI BIBREF22 , MultiNLI BIBREF23 , Quora Question Pairs BIBREF24 , and SST BIBREF25 . From experiments we show that the CAS-LSTMs consistently outperform typical stacked LSTMs, opening the possibility of performance improvement of architectures that use stacked LSTMs.\nOur contribution is summarized as follows.\nThis paper is organized as follows. We give a detailed description about the proposed method in § SECREF2 . Experimental results are given in § SECREF3 . We study prior work related to our objective in § SECREF4 and conclude in § SECREF5 .\nFrom experiments we show that the CAS-LSTMs consistently outperform typical stacked LSTMs, opening the possibility of performance improvement of architectures based on stacked LSTMs.",

        "evidence": "For UTD we use the Zero Resource Toolkit (ZRTools; Jansen and Van Durme, 2011). ZRTools uses dynamic time warping (DTW) to discover pairs of acoustically similar audio segments, and then uses graph clustering on overlapping pairs to form a hard clustering of the discovered segments. Replacing each discovered segment with its unique cluster label, or pseudoterm, gives us a partial, noisy transcription, or pseudotext (Fig. FIGREF4 ).\nIn creating a translation model from this data, we face a difficulty that does not arise in the parallel texts that are normally used to train translation models: the pseudotext does not represent all of the source words, since the discovered segments do not cover the full audio (Fig. FIGREF4 ). Hence we must not assume that our MT model can completely recover the translation of a test sentence. In these conditions, the language modeling and ordering assumptions of most MT models are unwarranted, so we instead use a simple bag-of-words translation model based only on co-occurrence: IBM Model 1 BIBREF11 with a Dirichlet prior over translation distributions, as learned by fast_align BIBREF12 . In particular, for each pseudoterm, we learn a translation distribution over possible target words. To translate a pseudoterm in test data, we simply return its highest-probability translation (or translations, as discussed in § SECREF5 ).\nThis setup implies that in order to translate, we must apply UTD on both the training and test audio. Using additional (not only training) audio in UTD increases the likelihood of discovering more clusters. We therefore generate pseudotext for the combined audio, train the MT model on the pseudotext of the training audio, and apply it to the pseudotext of the test data. This is fair since the UTD has access to only the audio.\nZRTools uses dynamic time warping (DTW) to discover pairs of acoustically similar audio segments, and then uses graph clustering on overlapping pairs to form a hard clustering of the discovered segments.

The Queensland National Trust named it a state icon of Queensland in 2006.\n\nA large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such as fishing and tourism. Other environmental pressures on the reef and its ecosystem include runoff of manmade pollutants, climate change accompanied by mass coral bleaching, dumping of dredging sludge and cyclic population outbreaks of the crown-of-thorns starfish. According to a study published in October 2012 by the Proceedings of the National Academy of Sciences, the reef has lost more than half its coral cover since 1985, a finding reaffirmed by a 2020 study which found over half of the reef's coral cover to have been lost between 1995 and 2017, with the effects of a widespread 2020 bleaching event not yet quantified.\n\nThe Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples, and is an important part of local groups' cultures and spirituality. The reef is a very popular destination for tourists, especially in the Whitsunday Islands and Cairns regions. Tourism is an important economic activity for the region, generating over AUD$3 billion per year. In November 2014, Google launched Google Underwater Street View in 3D of the Great Barrier Reef.",

His father was a self-employed tailor of modest means. Both his father and grandfather distinguished themselves in the major wars that Greece fought in the 20th century. He attended the second lyceum in Corfu where he excelled in his studies. In August 1967, a few months after the 21 April coup in Greece, Georgakis went to Italy to study as a geologist in Genoa. He received 5,000 drachmas per month from his father and this, according to friends' testimony, made him feel guilty for the financial burden his family endured so that he could attend a university.

        "answer": "Yes.",
        "evidence": "Table TABREF29 shows the results on four test sets as well as the average performance. Our method significantly outperforms the strong `many-to-many+pretrain' baseline by 3.6 and 2.2 BLEU scores respectively, indicating the proposed method is very effective that substantially improves the translation quality. Besides, both pre-training and multi-task learning can improve translation quality, and the pre-training settings (2nd-4th rows) are more effective compared to multi-task settings (5th-8th rows). We observe a performance degradation in the `triangle+pretrain' baseline. Compared to our method, where the decoder receives higher-level syntactic and semantic linguistic knowledge extracted from text encoder, their ASR decoder can only provide lower word-level linguistic information. Besides, since their model lacks text encoder and the architecture of ST decoder is different from MT decoder, their model cannot utilize the large-scale MT data in all the training stages. Interestingly, we find that the char-level models outperform the subword-level models in all settings, especially in vanilla baseline. A similar phenomenon is observed by BIBREF6 berard2018end. A possible explanation is that learning the alignments between speech frames and subword units in another language is notoriously difficult. Our method can bring more gains in the subword setting since our model is good at learning the text-to-text alignment and the subword-level alignment is more helpful to the translation quality.\nTable 4 shows the comparison between our best model with the cascaded systems, which combines the ASR model and MT model. In addition to a simple combination system, we also re-segment the ASR outputs before feeding to the MT system, denoted as ‘cascaded+re-seg’. Specifically, we train a seq2seq model (Bahdanau, Cho, and Bengio 2015) on the MT dataset, where the source side is a no punctuation sentence and the target side is a natural sentence. After that, we use the seq2seq model to add sentence boundaries and punctuation on ASR outputs. It can be seen that our end-toend model outperforms the simple cascaded model over 2 BLEU scores, and achieves a comparable performance with the ‘cascaded+re-seg’ system.",

        "question": "What is the best way to lose weight?",
        "evidence": "",
        "answer": "The best way to lose weight is to be in a calorie deficit. This means that you are consuming less calories than you expend. An easy way to confirm this deficit is to track your calorie intake with a calorie tracking application like MyFitnessPal. This helps you better understand the macronutrient composition (protein, carbohydrates, fat) of your food, and which foods are more calorically dense than others. One gram of protein has 4 calories per gram, one gram of carbohydrate has 4 calories per gram, and one gram of fat has 9 calories per gram. Each food that you consume is either one or a combination of these three macronutrients. It is possible to expend calories to create a larger deficit through exercise. There are many types of exercise, but most types can be categorized as either cardiovascular training or weight training. Both types of exercise are important, as cardiovascular exercises, such as walking, running, and biking, train your heart and burn calories during exercise. Weight-based training involves challenging your muscles with loads in order to make them stronger to handle larger loads and more volume. Weight-based training does not burn as many calories during exercise, however this type of training taxes your muscles so that they need to repair and thus burns more calories throughout the day after your training session. Weight-based training is important for strong muscles, bones, and tendons. The best way to lose weight involves a combination of a calorie-controlled diet, cardiovascular exercise, and weight-based training exercise sustained over a duration of time until you meet your weight goal. Once you meet your goal, it is then important to sustain these good habits and not revert back to the habits and behaviors you were previously engaged in that contributed to your weight gain.",

        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization.",

Meanwhile generative AI capabilities such as Dall-E, Stable Diffusion, and Midjourney are able to generate highly realistic and detailed images from text descriptions, demonstrating a level of creativity and imagination that was once thought to be exclusively human.\n\nHumans seem fundamentally wired to continuously advance technology and improve our knowledge and capabilities. Also, the human brain tends to think linearly, causing us to underestimate the exponential progress of technology. Companies and nations are incentivized by market forces and geopolitical game theory to pursue better intelligence through the advancement of AI.\n\nThe Future of Life Institute recently published Pause Giant AI Experiments: An Open Letter. The letter — with notable signatories including Elon Musk, Steve Wozniak and Andrew Yang — caused a stir, calling for a 6 month pause on advanced AI development:\n\n“Therefore, we call on all AI labs to immediately pause for at least 6 months the training of AI systems more powerful than GPT-4. This pause should be public and verifiable, and include all key actors. If such a pause cannot be enacted quickly, governments should step in and institute a moratorium.”\n\nMuch of the media and public discourse in response to this letter has focused on who signed it and pushing back on the notion that humanity faces an imminent existential threat of artificial superintelligence. Dystopian claims of runaway artificial intelligence seem hyperbolic to many people, and calling for a 6 month moratorium is not realistic. Good luck convincing China to “pause” their efforts in the AI arms race.\n\nBut are there no boundaries? Should we proceed with no guidelines?\n\nFor example …\n\nAre we comfortable outsourcing decisions to black box AI systems that lack transparency and explainability, making it impossible for humans to understand the reasoning behind decisions?\nShould we be worried about the development of AI-powered autonomous weapons that make decisions about the use of lethal force without human input?\nShould we be worried about the potential for malicious actors to use AI for nefarious purposes, such as sophisticated propaganda campaigns?\nAre our current laws, regulations and political systems equipped to handle the rapid influx of new AI alignment questions that society will grapple with in the very near future?\nAs AI becomes more advanced, it may become difficult to understand, which could lead to unintended outcomes. AI systems can behave in ways that are unforeseen and difficult to control. The AI alignment problem is a societal challenge that requires collaboration between researchers, engineers, entrepreneurs, policymakers, and the public. It will also require international cooperation between governments and the private sector. This is not just a technical challenge, but also a philosophical and ethical one.\n\nThe open letter mentioned above goes on to recommend:\n\n“AI research and development should be refocused on making today’s powerful, state-of-the-art systems more accurate, safe, interpretable, transparent, robust, aligned, trustworthy, and loyal.”\n\nThis is certainly a worthy goal, and it can be achieved by doing AI in the open. What we currently lack is a framework. Society needs a set of procedures and protocols to make the recommendation from The Future of Life Institute actionable.\n\nJointly, we must consider and debate the pros and cons of many ideas, including but not limited to:\n\nMandatory disclosure of model details, including training datasets, evaluation methodologies, and known biases\nDevelopment of a framework that establishes model monitoring and audit requirements for advanced AI systems\nImplementation of laws that impose liability for AI-caused harm\nEstablishment of a regulatory authority for oversight and tracking of highly capable AI systems\nThe first step in achieving a productive framework for safe AI development is an open dialogue among the many stakeholders involved, which includes everyone. We must rise above the hyper-politicized discourse that our dishonest and broken media often forces upon us. This topic is too important and the ramifications are too profound.

Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.\nAuroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles.\nIn northern latitudes, the effect is known as the aurora borealis or the northern lights. The former term was coined by Galileo in 1619, from the Roman goddess of the dawn and the Greek name for the north wind. The southern counterpart, the aurora australis or the southern lights, has features almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. The aurora australis is visible from high southern latitudes in Antarctica, Chile, Argentina, South Africa, New Zealand and Australia.

        "answer": "Through a combination of a shifter and three pedals: gas, brake, and clutch. Press down the clutch pedal with one foot, and the brake with your other foot first and then turn on the engine of the car. It is recommended to shift to neutral immediately after turning on your car and prior to departing. To shift between one of the engaged gears, typically marked 1, 2, 3, 4, 5 N (for neutral) and R (for reverse), press down on the clutch all the way to the floor and move the shifter to the desired location. Once the car is on and you're in neutral if you want to move forward, press and hold the clutch pedal to the floor and move the shifter to the \"1\" position. Slowly disengage the clutch pedal partially, and while disengaging slowly start to press down on the gas pedal. After gradually pressing more on the gas pedal, slowly remove your foot from the clutch entirely. This will start you in forward motion, and you will be restricted to the speed limit of 1st gear. You can track this limit through the RPM (revolutions per minute) gauge on the dashboard of your car. Typically you want to keep the RPMs between 1500-4000. If the RPMs start to decrease to 1500-2000 that is a sign you want to shift from a higher gear to a lower gear (i.e. 2nd gear to 1st gear), and as the RPMs increase to 4000, that is an indication you want to shift to a higher gear (i.e. 2nd gear to 3rd gear).",

In Canada, the term automated banking machine (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM over ABM. In British English, the terms cashpoint, cash machine and hole in the wall are most widely used. Other terms include any time money, cashline, tyme machine, cash dispenser, cash corner, bankomat, or bancomat. ATMs that are not operated by a financial institution are known as \"white-label\" ATMs.\n\nUsing an ATM, customers can access their bank deposit or credit accounts in order to make a variety of financial transactions, most notably cash withdrawals and balance checking, as well as transferring credit to and from mobile phones. ATMs can also be used to withdraw cash in a foreign country. If the currency being withdrawn from the ATM is different from that in which the bank account is denominated, the money will be converted at the financial institution's exchange rate. Customers are typically identified by inserting a plastic ATM card (or some other acceptable payment card) into the ATM, with authentication being by the customer entering a personal identification number (PIN), which must match the PIN stored in the chip on the card (if the card is so equipped), or in the issuing financial institution's database.",

The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nThe application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.",

To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nThe architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet.",

        "question": "What are Uncontacted peoples?",
        "evidence": "Uncontacted peoples are groups of indigenous peoples living without sustained contact with neighbouring communities and the world community. Groups who decide to remain uncontacted are referred to as indigenous peoples in voluntary isolation. Legal protections make estimating the total number of uncontacted peoples challenging, but estimates from the Inter-American Commission on Human Rights in the UN and the non-profit group Survival International point to between 100 and 200 uncontacted peoples numbering up to 10,000 individuals total. A majority of uncontacted peoples live in South America, particularly northern Brazil, where the Brazilian government and National Geographic estimate between 77 and 84 tribes reside.\n\nKnowledge of uncontacted peoples comes mostly from encounters with neighbouring indigenous communities and aerial footage.",
        "answer": "Uncontacted peoples generally refers to indigenous peoples who have remained largely isolated to the present day, maintaining their traditional lifestyles and functioning mostly independently from any political or governmental entities. However, European exploration and colonization during the early modern period brought indigenous peoples worldwide into contact with colonial settlers and explorers. As such, most indigenous groups have had some form of contact with other peoples. The term \"uncontacted\" therefore refers to a lack of sustained contact with the majority of non-indigenous society at the present time.\n\nThe Inter-American Commission on Human Rights refers to uncontacted peoples as \"indigenous peoples in voluntary isolation.\" These groups are defined by their general rejection of contact with anyone outside of their own people. This definition also includes groups who have previously had sustained contact with the majority non-indigenous society but have chosen to return to isolation and no longer maintain contact. As such uncontacted peoples are understood not as living in an anachronistic state of nature but rather as contemporaries of modernity.\n\nA 2009 United Nations report also classified \"peoples in initial contact\" as sharing the same characteristics but beginning to regularly communicate with and integrate into mainstream society.\n\nTo highlight their agency in staying uncontacted or isolated, international organizations emphasize calling them \"indigenous peoples in isolation\" or \"in voluntary isolation\". Otherwise they have also been called \"hidden peoples\" or \"uncontacted tribes\".\n\nHistorically European colonial ideas of uncontacted peoples, and their colonial claims over them, were informed by the imagination of and search for Prester John, king of a wealthy Christian realm in isolation, as well as the Ten Lost Tribes of Israel, identifying uncontacted peoples as \"lost tribes\".\n\nInternational organizations have highlighted the importance of protecting indigenous peoples' environment and lands, the importance of protecting them from exploitation or abuse, and the importance of no contact in order to prevent the spread of modern diseases.\n\nHistoric exploitation and abuse at the hands of the majority group have led many governments to give uncontacted people their lands and legal protection. Many indigenous groups live on national forests or protected grounds, such as the Vale do Javari in Brazil or the North Sentinel Island in India.\n\nMuch of the contention over uncontacted peoples has stemmed from governments' desire to extract natural resources. In the 1960s and 1970s, Brazil's federal government attempted to assimilate and integrate native groups living in the Amazon jungle in order to use their lands for farming. Their efforts were met with mixed success and criticism until, in 1987, Brazil created the Department of Isolated Indians inside of FUNAI (Fundação Nacional do Índio), Brazil's Indian Agency. FUNAI was successful in securing protected lands which have allowed certain groups to remain relatively uncontacted until the present day.\n\nA different outcome occurred in Colombia when the Nukak tribe of indigenous people was contacted by an evangelical group. The tribe was receptive to trade and eventually moved in order to have closer contact with settlers. This led to an outbreak of respiratory infections, violent clashes with narco-traffickers, and the death of hundreds of the Nukak, more than half of the tribe. Eventually, the Colombian government forcibly relocated the tribe to a nearby town where they received food and government support but were reported as living in poverty.\n\nThe threats to the Nukak tribe are generally shared by all peoples in isolation, particularly the outside world's desire to exploit their lands. This can include lumbering, ranching and farming, land speculation, oil prospecting and mining, and poaching. For example, then Peruvian President Alan García claimed in 2007 that uncontacted groups were only a \"fabrication of environmentalists bent on halting oil and gas exploration\". As recently as 2016, a Chinese subsidiary mining company in Bolivia ignored signs that they were encroaching on uncontacted tribes, and attempted to cover it up. In addition to commercial pursuits, other people such as missionaries can inadvertently cause great damage.\n\nIt was those threats, combined with attacks on their tribe by illegal cocaine traffickers, that led a group of Acre Indians to make contact with a village in Brazil and subsequently with the federal government in 2014. This behaviour suggests that many tribes are aware of the outside world and choose not to make contact unless motivated by fear or self-interest. Satellite images suggest that some tribes intentionally migrate away from roads or logging operations in order to remain secluded.\n\nIndigenous rights activists have often advocated that indigenous peoples in isolation be left alone, saying that contact will interfere with their right to self-determination as peoples. On the other hand, experience in Brazil suggests isolating peoples might want to have trading relationships and positive social connections with others, but choose isolation out of fear of conflict or exploitation. The Brazilian state organization National Indian Foundation (FUNAI) in collaboration with anthropological experts has chosen to make controlled initial contact with tribes. The organization operates 15 trading posts throughout protected territory where tribes can trade for metal tools and cooking instruments. The organization also steps in to prevent some conflicts and deliver vaccinations. However, FUNAI has been critical of political will in Brazil, reporting that it only received 15% of its requested budget in 2017. In 2018, after consensus among field agents, FUNAI released videos and images of several tribes under their protection. Although the decision was criticized, the director of the Isolated Indian department, Bruno Pereira, responded that \"The more the public knows and the more debate around the issue, the greater the chance of protecting isolated Indians and their lands\". He shared that the organization has been facing mounting political pressure to open up lands to commercial companies. He also justified the photography by explaining that FUNAI was investigating a possible massacre against the Flechieros tribe.\n\nRecognizing the myriad problems with contact, the United Nations Human Rights Council in 2009 and the Inter-American Commission on Human Rights in 2013 introduced guidelines and recommendations that included a right to choose self-isolation.\n\nThere have been reports of human safaris in India's Andaman Islands and in Peru, where tourism companies attempt to help tourists see uncontacted or recently contacted peoples. This practice is controversial.",

        "question": "Why are model-based attacks generally seen as grey box attacks?",
        "answer": "Because it requires access to target classifier during training phase.",
        "evidence": "Most existing adversarial attack methods for text inputs are derived from those for image inputs. These methods can be categorised into three types including gradient-based attacks, optimisation-based attacks and model-based attacks.\nGradient-based attacks are mainly white-box attacks that rely on calculating the gradients of the target classifier with respect to the input representation. This class of attacking methods BIBREF6, BIBREF7, BIBREF6 are mainly derived from the fast gradient sign method (FGSM) BIBREF1, and it has been shown to be effective in attacking CV classifiers. However, these gradient-based methods could not be applied to text directly because perturbed word embeddings do not necessarily map to valid words. Other methods such as DeepFool BIBREF8 that rely on perturbing the word embedding space face similar roadblocks. BIBREF5 propose to use nearest neighbour search to find the closest word to the perturbed embedding.\nBoth optimisation-based and model-based attacks treat adversarial attack as an optimisation problem where the constraints are to maximise the loss of target classifiers and to minimise the difference between original and adversarial examples. Between these two, the former uses optimisation algorithms directly; while the latter trains a seperate model to generate adversarial examples and therefore involves a training process. Some of the most effective attacks for images are achieved by optimisation-based methods, such as the L-BFGS attack BIBREF1 and the C&W attack BIBREF9 in white-box attacks and the ZOO method BIBREF10 in black-box attacks. For texts, the white-box attack HotFlip BIBREF3 and black-box attack DeepWordBug BIBREF11 and TextBugger BIBREF12 are proposed in this category.\nIn a similar vein, a few model-based attacks have been proposed for images, e.g. BIBREF13 design a generative adversarial network (GAN) to generate the image perturbation from a noise map. The attacking method and target classifier typically form a single large network and the attacking method is trained using the loss from the target classifier. For this reason, it is not very straightforward to use these model-based techniques for text because there is a discontinuity in the network (since words in the adversarial examples are discrete) and so it is not fully differentiable.\nModel-based attacks are generally seen as greybox attacks as it requires access to target classifier during training phase, but once it’s trained it can generate adversarial examples independently.",

The data was recorded under a partnership between the AVENUE project, funded by the US National Science Foundation at Carnegie Mellon University, the Chilean Ministry of Education (Mineduc), and the Instituto de Estudios Indígenas at Universidad de La Frontera, originally spanning 170 hours of audio. We have recently cleaned the data and are releasing it publicly for the first time (although it has been shared with individual researchers in the past) along with NLP baselines.\nThe recordings were transcribed and translated into Spanish at the Instituto de Estudios Indígenas at Universidad de La Frontera. The corpus covers three dialects of Mapudungun: about 110 hours of Nguluche, 20 hours of Lafkenche and 10 hours of Pewenche. The three dialects are quite similar, with some minor semantic and phonetic differences. The fourth traditionally distinguished dialect, Huilliche, has several grammatical differences from the other three and is classified by Ethnologue as a separate language, iso 639-3: huh, and as nearly extinct.\nThe recordings are restricted to a single domain: primary, preventive, and treatment health care, including both Western and Mapuche traditional medicine. The recording sessions were conducted as interactive conversations so as to be natural in Mapuche culture, and they were open-ended, following an ethnographic approach. The interviewer was trained in these methods along with the use of the digital recording systems that were available at the time. We also followed human subject protocol. Each person signed a consent form to release the recordings for research purposes and the data have been accordingly anonymized. Because Machi (traditional Mapuche healers) were interviewed, we asked the transcribers to delete any culturally proprietary knowledge that a Machi may have revealed during the conversation. Similarly, we deleted any names or any information that may identify the participants.\nThe corpus is culturally relevant because it was created by Mapuche people, using traditional ways of relating to each other in conversations. They discussed personal experiences with primary health care in the traditional Mapuche system and the Chilean health care system, talking about illnesses and the way they were cured. The participants ranged from 16 years old to 100 years old, almost in equal numbers of men and women, and they were all native speakers of Mapudungun.\nWe created two training sets, one appropriate for single-speaker speech synthesis experiments, and one appropriate for multiple-speaker speech recognition and machine translation experiments.",

To verify the importance of a good initialization, we train a RAMEN$_{\\textsc {base}}$+RoBERTa with foreign word-embeddings are initialized randomly from $\\mathcal {N}(0, {1}{d^2})$. For a fair comparison, we use the same hyper-parameters in §SECREF27. Table TABREF36 shows the results of XNLI and UD parsing of random initialization. In comparison to the initialization using aligned fastText vectors, random initialization decreases the zero-shot performance of RAMEN$_{\\textsc {base}}$ by 15.9% for XNLI and 27.8 points for UD parsing on average. We also see that zero-shot parsing of SOV languages (Arabic and Hindi) suffers random initialization.\nAll the RAMEN models are built from English and tuned on English for zero-shot cross-lingual tasks. It is reasonable to expect RAMENs do well in those tasks as we have shown in our experiments. But are they also a good feature extractor for supervised tasks? We offer a partial answer to this question by evaluating our model for supervised dependency parsing on UD datasets.\nWe used train/dev/test splits provided in UD to train and evaluate our RAMEN-based parser. Table TABREF38 summarizes the results (LAS) of our supervised parser. For a fair comparison, we choose mBERT as the baseline and all the RAMEN models are initialized from aligned fastText vectors. With the same architecture of 12 Transformer layers, RAMEN$_{\\textsc {base}}$+BERT performs competitive to mBERT and outshines mBERT by +1.2 points for Vietnamese. The best LAS results are obtained by RAMEN$_{\\textsc {large}}$+RoBERTa with 24 Transformer layers. Overall, our results indicate the potential of using contextual representations from RAMEN for supervised tasks.\nWe evaluate the performance of RAMEN+RoBERTa$_{\\textsc {base}}$ (initialized from monolingual data) at each training steps: initialization of word embeddings (0K update), fine-tuning target embeddings (25K), and fine-tuning the model on both English and target language (at each 25K updates). The results are presented in Figure FIGREF40.\nWithout fine-tuning, the average accuracy of XLNI is 39.7% for a three-ways classification task, and the average LAS score is 3.6 for dependency parsing. We see the biggest leap in the performance after 50K updates. While semantic similarity task profits significantly at 25K updates of the target embeddings, syntactic task benefits with further fine-tuning the encoder. This is expected since the target languages might exhibit different syntactic structures than English and fine-tuning encoder helps to capture language specific structures. We observe a substantial gain of 19-30 LAS for all languages except French after 50K updates.\nLanguage similarities have more impact on transferring syntax than semantics. Without tuning the English encoder, French enjoys 50.3 LAS for being closely related to English, whereas Arabic and Hindi, SOV languages, modestly reach 4.2 and 6.4 points using the SVO encoder. Although Chinese has SVO order, it is often seen as head-final while English is strong head-initial. Perhaps, this explains the poor performance for Chinese.\nInitializing foreign embeddings is the backbone of our approach.

It is reasonable to expect RAMENs do well in those tasks as we have shown in our experiments. But are they also a good feature extractor for supervised tasks? We offer a partial answer to this question by evaluating our model for supervised dependency parsing on UD datasets.\nWe used train/dev/test splits provided in UD to train and evaluate our RAMEN-based parser. Table TABREF38 summarizes the results (LAS) of our supervised parser. For a fair comparison, we choose mBERT as the baseline and all the RAMEN models are initialized from aligned fastText vectors. With the same architecture of 12 Transformer layers, RAMEN$_{\\textsc {base}}$+BERT performs competitive to mBERT and outshines mBERT by +1.2 points for Vietnamese. The best LAS results are obtained by RAMEN$_{\\textsc {large}}$+RoBERTa with 24 Transformer layers. Overall, our results indicate the potential of using contextual representations from RAMEN for supervised tasks.\nWe evaluate the performance of RAMEN+RoBERTa$_{\\textsc {base}}$ (initialized from monolingual data) at each training steps: initialization of word embeddings (0K update), fine-tuning target embeddings (25K), and fine-tuning the model on both English and target language (at each 25K updates). The results are presented in Figure FIGREF40.\nWithout fine-tuning, the average accuracy of XLNI is 39.7% for a three-ways classification task, and the average LAS score is 3.6 for dependency parsing. We see the biggest leap in the performance after 50K updates. While semantic similarity task profits significantly at 25K updates of the target embeddings, syntactic task benefits with further fine-tuning the encoder. This is expected since the target languages might exhibit different syntactic structures than English and fine-tuning encoder helps to capture language specific structures. We observe a substantial gain of 19-30 LAS for all languages except French after 50K updates.\nLanguage similarities have more impact on transferring syntax than semantics. Without tuning the English encoder, French enjoys 50.3 LAS for being closely related to English, whereas Arabic and Hindi, SOV languages, modestly reach 4.2 and 6.4 points using the SVO encoder. Although Chinese has SVO order, it is often seen as head-final while English is strong head-initial. Perhaps, this explains the poor performance for Chinese.\nAre contextual representations from RAMEN also good for supervised parsing?****Overall, our results indicate the potential of using contextual representations from RAMEN for supervised tasks.",

        "evidence": "Language model pre-training has proven to be highly effective in learning universal language representations from large-scale unlabeled data. ELMo BIBREF0, GPT BIBREF1 and BERT BIBREF2 have achieved great success in many NLP tasks, such as sentiment classification BIBREF3, natural language inference BIBREF4, and question answering BIBREF5.\nDespite its empirical success, BERT's computational efficiency is a widely recognized issue because of its large number of parameters. For example, the original BERT-Base model has 12 layers and 110 million parameters. Training from scratch typically takes four days on 4 to 16 Cloud TPUs. Even fine-tuning the pre-trained model with task-specific dataset may take several hours to finish one epoch. Thus, reducing computational costs for such models is crucial for their application in practice, where computational resources are limited.\nMotivated by this, we investigate the redundancy issue of learned parameters in large-scale pre-trained models, and propose a new model compression approach, Patient Knowledge Distillation (Patient-KD), to compress original teacher (e.g., BERT) into a lightweight student model without performance sacrifice. In our approach, the teacher model outputs probability logits and predicts labels for the training samples (extendable to additional unannotated samples), and the student model learns from the teacher network to mimic the teacher's prediction.\nDifferent from previous knowledge distillation methods BIBREF6, BIBREF7, BIBREF8, we adopt a patient learning mechanism: instead of learning parameters from only the last layer of the teacher, we encourage the student model to extract knowledge also from previous layers of the teacher network. We call this `Patient Knowledge Distillation'. This patient learner has the advantage of distilling rich information through the deep structure of the teacher network for multi-layer knowledge distillation.\nWe also propose two different strategies for the distillation process: ($i$) PKD-Last: the student learns from the last $k$ layers of the teacher, under the assumption that the top layers of the original network contain the most informative knowledge to teach the student; and ($ii$) PKD-Skip: the student learns from every $k$ layers of the teacher, suggesting that the lower layers of the teacher network also contain important information and should be passed along for incremental distillation.\nWe evaluate the proposed approach on several NLP tasks, including Sentiment Classification, Paraphrase Similarity Matching, Natural Language Inference, and Machine Reading Comprehension. Experiments on seven datasets across these four tasks demonstrate that the proposed Patient-KD approach achieves superior performance and better generalization than standard knowledge distillation methods BIBREF6, with significant gain in training efficiency and storage reduction while maintaining comparable model accuracy to original large models. To the authors' best knowledge, this is the first known effort for BERT model compression.\nWe also propose two different strategies for the distillation process: ($i$) PKD-Last: the student learns from the last $k$ layers of the teacher, under the assumption that the top layers of the original network contain the most informative knowledge to teach the student; and ($ii$) PKD-Skip: the student learns from every $k$ layers of the teacher, suggesting that the lower layers of the teacher network also contain important information and should be passed along for incremental distillation.",

He published two poetry books: Falenas, in 1870, and Americanas, in 1875. Their weak reception made him explore other literary genres.\n\nHe wrote five romantic novels: Ressurreição, A Mão e a Luva, Helena and Iaiá Garcia. The books were a success with the public, but literary critics considered them mediocre. Machado suffered repeated attacks of epilepsy, apparently related to hearing of the death of his old friend José de Alencar. He was left melancholic, pessimistic and fixed on death. His next book, marked by \"a skeptical and realistic tone\": Memórias Póstumas de Brás Cubas (Posthumous Memoirs of Brás Cubas, also translated as Epitaph of a Small Winner), is widely considered a masterpiece. By the end of the 1880s, Machado had gained wide renown as a writer.\n\nAlthough he was opposed to slavery, he never spoke against it in public. He avoided discussing politics. He was criticized by the abolitionist José do Patrocínio and by the writer Lima Barreto for staying away from politics, especially the cause of abolition. He was also criticized by them for having married a white woman. Machado was caught by surprise with the monarchy overthrown on 15 November 1889. Machado had no sympathy towards republicanism, as he considered himself a liberal monarchist and venerated Pedro II, whom he perceived as \"a humble, honest, well-learned and patriotic man, who knew how to make of a throne a chair [for his simplicity], without diminishing its greatness and respect.\" When a commission went to the public office where he worked to remove the picture of the former emperor, the shy Machado defied them: \"The picture got in here by an order and it shall leave only by another order.\"\n\nThe birth of the Brazilian republic made Machado become more critical and an observer of the Brazilian society of his time. From then on, he wrote \"not only the greatest novels of his time, but the greatest of all time of Brazilian literature.\" Works such as Quincas Borba (Philosopher or Dog?) (1891), Dom Casmurro (1899), Esaú e Jacó (1904) and Memorial de Aires (1908), considered masterpieces, were successes with both critics and the public.

        "answer": "The unigram LDA topic model and LDA topic model.",
        "evidence": "For evaluating topics with automatic quality measures, we used several English text collections and one Russian collection (Table TABREF7 ). We experiment with three thesauri: WordNet (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms), and Russian thesaurus RuThes (115 thousand entries) BIBREF19 .\nAt the preprocessing step, documents were processed by morphological analyzers. Also, we extracted noun groups as described in BIBREF16 . As baselines, we use the unigram LDA topic model and LDA topic model with added 1000 ngrams with maximal NC-value BIBREF20 extracted from the collection under analysis.\nAs it was found before BIBREF14 , BIBREF16 , the addition of ngrams without accounting relations between their components considerably worsens the perplexity because of the vocabulary growth (for perplexity the less is the better) and practically does not change other automatic quality measures (Table 2).\nWe add the Wordnet data in the following steps. At the first step, we include WordNet synonyms (including multiword expressions) into the proposed similarity sets (LDA-Sim+WNsyn). At this step, frequencies of synonyms found in the same document are summed up in process LDA topic learning as described in Algorithm SECREF3 . We can see that the kernel uniqueness becomes very low, topics are very close to each other in content (Table 2: LDA-Sim+WNsyn). At the second step, we add word direct relatives (hyponyms, hypernyms, etc.) to similarity sets. Now the frequencies of semantically related words are added up enhancing the contribution into all topics of the current document.\nThe Table 2 shows that these two steps lead to great degradation of the topic model in most measures in comparison to the initial unigram model: uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times (Table 2: LDA-Sim+WNsynrel). It is evident that at this step the model has a poor quality. When we look at the topics, the cause of the problem seems to be clear. We can see the overgeneralization of the obtained topics. The topics are built around very general words such as \"person\", \"organization\", \"year\", etc. These words were initially frequent in the collection and then received additional frequencies from their frequent synonyms and related words.\nThen we suppose that these general words were used in texts to discuss specific events and objects, therefore, we change the constructions of the similarity sets in the following way: we do not add word hyponyms to its similarity set. Thus, hyponyms, which are usually more specific and concrete, should obtain additional frequencies from upper synsets and increase their contributions into the document topics. But the frequencies and contribution of hypernyms into the topic of the document are not changed. And we see the great improvement of the model quality: the kernel uniqueness considerably improves, perplexity decreases to levels comparable with the unigram model, topic coherence characteristics also improve for most collections (Table 2:LDA-Sim+WNsynrel/hyp).\nWe further use the WordNet-based similarity sets with n-grams having the same components as described in BIBREF16 . All measures significantly improve for all collections (Table 2:LDA-Sim+WNsr/hyp+Ngrams). At the last step, we try to apply the same approach to ngrams that was previously utilized to hyponym-hypernym relations: frequencies of shorter ngrams and words are summed to frequencies of longer ngrams but not vice versa. In this case we try to increase the contribution of more specific longer ngrams into topics. It can be seen (Table 2) that the kernel uniqueness grows significantly, at this step it is 1.3-1.6 times greater than for the baseline models achieving 0.76 on the ACL collection (Table 2:LDA-Sim+WNsr/hyp+Ngrams/l).\nAt the second series of the experiments, we applied EuroVoc information retrieval thesaurus to two European Union collections: Europarl and JRC. In content, the EuroVoc thesaurus is much smaller than WordNet, it contains terms from economic and political domains and does not include general abstract words. The results are shown in Table 3. It can be seen that inclusion of EuroVoc synsets improves the topic coherence and increases kernel uniqueness (in contrast to results with WordNet). Adding ngrams further improves the topic coherence and kernel uniqueness.\nAt last we experimented with the Russian banking collection and utilized RuThes thesaurus. In this case we obtained improvement already on RuThes synsets and again adding ngrams further improved topic coherence and kernel uniqueness (Table 4).\nIt is worth noting that adding ngrams sometimes worsens the TC-NPMI measure, especially on the JRC collection. This is due to the fact that in these evaluation frameworks, the topics' top elements contain a lot of multiword expressions, which rarely occur in Wikipedia, used for the coherence calculation, therefore the utilized automatic coherence measures can have insufficient evidence for correct estimates.\nAs baselines, we use the unigram LDA topic model and LDA topic model with added 1000 ngrams with maximal NCvalue [21] extracted from the collection under analysis.",

        "evidence": "First, to operationalize, we say that term $i$ is associated with gender $j$ if, when discussing individuals of gender $j$, $i$ is used with unusual frequency – which we can check with statistical hypothesis tests. Let $f_i$ represent the likelihood of $i$ appearing when discussing women or men. $f_i$ is unknown, but we can model the distribution of all possible $f_i$ using the corpus of texts that we have from the domain. We construct a gender-balanced version of the corpus by randomly undersampling the more prevalent gender until the proportions of each gender are equal. Assuming a non-informative prior distribution on $f_i$, the posterior distribution is Beta($k_i$, $N - k_i$), where $k_i$ is the count of $i$ in the gender-balanced corpus and $N$ is the total count of words in that corpus.\nAs BIBREF10 discuss, “the distribution of the gender-specific counts can be described by an integral over all possible $f_i$. This integral defines the Beta-Binomial distribution BIBREF29, and has a closed form solution.” We say that term $i$ is significantly associated with gender $j$ if the cumulative distribution at $k_{ij}$ (the count of $i$ in the $j$ portion of the gender-balanced corpus) is $p \\le 0.05$. As in the original work, we apply the Bonferroni correction BIBREF30 for multiple comparisons because we are computing statistical tests for thousands of hypotheses.\nFirst, we trained domain-specific word embeddings using the Word2Vec BIBREF33 CBOW model ($w \\in R^{100}$). Then, we used k-means clustering to cluster the embeddings of the gender-associated words. Since k-means may converge at local optima, we ran the algorithm 50 times and kept the model with the lowest sum of squared errors.\nTo automatically label the clusters, we combined the grounded knowledge of WordNet BIBREF34 and context-sensitive strengths of domain-specific word embeddings. Our algorithm is similar to BIBREF28's approach, but we extend their method by introducing domain-specific word embeddings for clustering as well as a new technique for sense disambiguation. Given a cluster, our algorithm proceeds with the following three steps:\nSense disambiguation: The goal is to assign each cluster word to one of its WordNet synsets; let $S$ represent the collection of chosen synsets. We know that these words have been clustered in domain-specific embedding space, which means that in the context of the domain, these words are very close semantically. Thus, we choose $S^*$ that minimizes the total distance between its synsets.\nCandidate label generation: In this step, we generate $L$, the set of possible cluster labels. Our approach is simple: we take the union of all hypernyms of the synsets in $S^*$.\nCandidate label ranking: Here, we rank the synsets in $L$. We want labels that are as close to all of the synsets in $S^*$ as possible; thus, we score the candidate labels by the sum of their distances to each synset in $S^*$ and we rank them from least to most distance.\nIn steps 1 and 3, we use WordNet pathwise distance, but we encourage the exploration of other distance representations as well.\nTo automatically label the clusters, we combined the grounded knowledge of WordNet (Miller, 1995) and context-sensitive strengths of domain-specific word embeddings.",

Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

        "question": "How many records do they use to train their text embedding?",
        "answer": "13 million records.",
        "evidence": "The vast amounts of data collected by healthcare providers in conjunction with modern data analytics techniques present a unique opportunity to improve health service provision and the quality and safety of medical care for patient benefit BIBREF0 . Much of the recent research in this area has been on personalised medicine and its aim to deliver better diagnostics aided by the integration of diverse datasets providing complementary information. Another large source of healthcare data is organisational. In the United Kingdom, the National Health Service (NHS) has a long history of documenting extensively the different aspects of healthcare provision. The NHS is currently in the process of increasing the availability of several databases, properly anonymised, with the aim of leveraging advanced analytics to identify areas of improvement in NHS services.\nOne such database is the National Reporting and Learning System (NRLS), a central repository of patient safety incident reports from the NHS in England and Wales. Set up in 2003, the NRLS now contains more than 13 million detailed records. The incidents are reported using a set of standardised categories and contain a wealth of organisational and spatio-temporal information (structured data), as well as, crucially, a substantial component of free text (unstructured data) where incidents are described in the `voice' of the person reporting. The incidents are wide ranging: from patient accidents to lost forms or referrals; from delays in admission and discharge to serious untoward incidents, such as retained foreign objects after operations. The review and analysis of such data provides critical insight into the complex functioning of different processes and procedures in healthcare towards service improvement for safer carer.\nAlthough statistical analyses are routinely performed on the structured component of the data (dates, locations, assigned categories, etc), the free text remains largely unused in systematic processes. Free text is usually read manually but this is time-consuming, meaning that it is often ignored in practice, unless a detailed review of a case is undertaken because of the severity of harm that resulted. There is a lack of methodologies that can summarise content and provide content-based groupings across the large volume of reports submitted nationally for organisational learning. Methods that could provide automatic categorisation of incidents from the free text would sidestep problems such as difficulties in assigning an incident category by virtue of a priori pre-defined lists in the reporting system or human error, as well as offering a unique insight into the root cause analysis of incidents that could improve the safety and quality of care and efficiency of healthcare services.\nOur goal in this work is to showcase an algorithmic methodology that detects content-based groups of records in a given dataset in an unsupervised manner, based only on the free and unstructured textual description of the incidents. To do so, we combine recently developed deep neural-network high-dimensional text-embedding algorithms with network-theoretical methods. In particular, we apply multiscale Markov Stability (MS) community detection to a sparsified geometric similarity graph of documents obtained from text vector similarities. Our method departs from traditional natural language processing tools, which have generally used bag-of-words (BoW) representation of documents and statistical methods based on Latent Dirichlet Allocation (LDA) to cluster documents BIBREF1 . More recent approaches have used deep neural network based language models clustered with k-means, without a full multiscale graph analysis BIBREF2 . There have been some previous applications of network theory to text analysis. For example, Lanchichinetti and co-workers BIBREF3 used a probabilistic graph construction analysed with the InfoMap algorithm BIBREF4 ; however, their community detection was carried out at a single-scale and the representation of text as BoW arrays lacks the power of neural network text embeddings. The application of multiscale community detection allows us to find groups of records with consistent content at different levels of resolution; hence the content categories emerge from the textual data, rather than fitting with pre-designed classifications. The obtained results could thus help mitigate possible human error or effort in finding the right category in complex category classification trees.\nWe showcase the methodology through the analysis of a dataset of patient incidents reported to the NRLS. First, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used). We then analyse a subset of 3229 records reported from St Mary's Hospital, London (Imperial College Healthcare NHS Trust) over three months in 2014 to extract clusters of incidents at different levels of resolution in terms of content. Our method reveals multiple levels of intrinsic structure in the topics of the dataset, as shown by the extraction of relevant word descriptors from the grouped records and a high level of topic coherence. Originally, the records had been manually coded by the operator upon reporting with up to 170 features per case, including a two-level manual classification of the incidents. Therefore, we also carried out an a posteriori comparison against the hand-coded categories assigned by the reporter (healthcare personnel) at the time of the report submission. Our results show good overall correspondence with the hand-coded categories across resolutions and, specifically, at the medium level of granularity. Several of our clusters of content correspond strongly to well-defined categories, yet our results also reveal complementary categories of incidents not defined in the external classification. In addition, the tuning of the granularity afforded by the method can be used to provide a distinct level of resolution in certain areas corresponding to specialise or particular sub-themes.\nFirst, we use the 13 million records collected by the NRLS since 2004 to train our text embedding (although a much smaller corpus can be used).",

        "question": "What is the authors' motivation for argumentation mining stems?",
        "answer": "The motivation for argumentation mining stems from a practical information seeking perspective from the user-generated content on the Web.",
        "evidence": "The art of argumentation has been studied since the early work of Aristotle, dating back to the 4th century BC BIBREF0 . It has been exhaustively examined from different perspectives, such as philosophy, psychology, communication studies, cognitive science, formal and informal logic, linguistics, computer science, educational research, and many others. In a recent and critically well-acclaimed study, Mercier.Sperber.2011 even claim that argumentation is what drives humans to perform reasoning. From the pragmatic perspective, argumentation can be seen as a verbal activity oriented towards the realization of a goal BIBREF1 or more in detail as a verbal, social, and rational activity aimed at convincing a reasonable critic of the acceptability of a standpoint by putting forward a constellation of one or more propositions to justify this standpoint BIBREF2 .\nAnalyzing argumentation from the computational linguistics point of view has very recently led to a new field called argumentation mining BIBREF3 . Despite the lack of an exact definition, researchers within this field usually focus on analyzing discourse on the pragmatics level and applying a certain argumentation theory to model and analyze textual data at hand.\nOur motivation for argumentation mining stems from a practical information seeking perspective from the user-generated content on the Web. For example, when users search for information in user-generated Web content to facilitate their personal decision making related to controversial topics, they lack tools to overcome the current information overload. One particular use-case example dealing with a forum post discussing private versus public schools is shown in Figure FIGREF4 . Here, the lengthy text on the left-hand side is transformed into an argument gist on the right-hand side by (i) analyzing argument components and (ii) summarizing their content. Figure FIGREF5 shows another use-case example, in which users search for reasons that underpin certain standpoint in a given controversy (which is homeschooling in this case). In general, the output of automatic argument analysis performed on the large scale in Web data can provide users with analyzed arguments to a given topic of interest, find the evidence for the given controversial standpoint, or help to reveal flaws in argumentation of others.\nSatisfying the above-mentioned information needs cannot be directly tackled by current methods for, e.g., opinion mining, questions answering, or summarization and requires novel approaches within the argumentation mining field. Although user-generated Web content has already been considered in argumentation mining, many limitations and research gaps can be identified in the existing works. First, the scope of the current approaches is restricted to a particular domain or register, e.g., hotel reviews BIBREF5 , Tweets related to local riot events BIBREF6 , student essays BIBREF7 , airline passenger rights and consumer protection BIBREF8 , or renewable energy sources BIBREF9 . Second, not all the related works are tightly connected to argumentation theories, resulting into a gap between the substantial research in argumentation itself and its adaptation in NLP applications. Third, as an emerging research area, argumentation mining still suffers from a lack of labeled corpora, which is crucial for designing, training, and evaluating the algorithms. Although some works have dealt with creating new data sets, the reliability (in terms of inter-annotator agreement) of the annotated resources is often unknown BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 .\nAnnotating and automatically analyzing arguments in unconstrained user-generated Web discourse represent challenging tasks. So far, the research in argumentation mining “has been conducted on domains like news articles, parliamentary records and legal documents, where the documents contain well-formed explicit arguments, i.e., propositions with supporting reasons and evidence present in the text” BIBREF8 . [p. 50]Boltuzic.Snajder.2014 point out that “unlike in debates or other more formal argumentation sources, the arguments provided by the users, if any, are less formal, ambiguous, vague, implicit, or often simply poorly worded.” Another challenge stems from the different nature of argumentation theories and computational linguistics. Whereas computational linguistics is mainly descriptive, the empirical research that is carried out in argumentation theories does not constitute a test of the theoretical model that is favored, because the model of argumentation is a normative instrument for assessing the argumentation BIBREF15 . So far, no fully fledged descriptive argumentation theory based on empirical research has been developed, thus feasibility of adapting argumentation models to the Web discourse represents an open issue.\nThese challenges can be formulated into the following research questions:\nIn this article, we push the boundaries of the argumentation mining field by focusing on several novel aspects. We tackle the above-mentioned research questions as well as the previously discussed challenges and issues. First, we target user-generated Web discourse from several domains across various registers, to examine how argumentation is communicated in different contexts. Second, we bridge the gap between argumentation theories and argumentation mining through selecting the argumenation model based on research into argumentation theories and related fields in communication studies or psychology. In particular, we adapt normative models from argumentation theory to perform empirical research in NLP and support our application of argumentation theories with an in-depth reliability study. Finally, we use state-of-the-art NLP techniques in order to build robust computational models for analyzing arguments that are capable of dealing with a variety of genres on the Web.\nOur motivation for argumentation mining stems from a practical information seeking perspective from the user-generated content on the Web.",

While defending the port of Sulina, she engaged Russian gunboats in an inconclusive action. She was laid up for twenty years, until the outbreak of the Greco-Turkish War in 1897, which highlighted the badly deteriorated state of the Ottoman fleet.

        "evidence": "",
        "answer": "If the bunker is near the pin, use your sand-wedge.  Also, ensure you properly examined the green, to understand its shape and slope.  Combine this with an understanding of your own skill levels to make a decision on where you wish the ball to land.  For example,  the more skilled you are at these shots, the more precise a location you can identify.  Conversely, the less skilled you are, the less precise you can be in your chosen location, and consequently the more you need to consider a range of potential directions.  In those latter cases, it is best to aim towards the middle of the green rather than the exact placement of the pin.  Once you've made a decision on location, go up to your ball in the bunker.  (Pro-tip: don't forget to bring the rake with you).  Choose an open stance, where your legs are aiming roughly 45 degrees more to the left of the selected landing location.  If you're left-handed, the reverse is true, and your legs are aiming to the right of the intended direction/location.  Dig your shoes roughly an inch into the sand, to get a solid footing.  Next, bring your club face down to the ball, without actually touching the sand (it is not legal to make contact with the sand prior to contact with the ball).  Open the club face so that it aims towards the intended location.  Look one more time at the intended direction, then look down at the ball, and commence your backswing.  The plane of your backswing should be out, inline with the direction of your legs, and roughly three quarters the length of a full swing.  Firmly and confidently accelerate in your downswing, and aim to make contact with the sand roughly half an inch behind the ball.  The sand between the ball and the club head will blunt some of the force from the swing, thereby reducing ball travel distance, while still conveying spin.  A well hit shot can cause the ball to land on the green and immediately stop, possibly even moving back in the direction of the player.  The force in the downswing, combined with the amount of sand caught by the club head, are significant contributors to the amount of backspin on the ball.

        "evidence": "We tested the proposed UTCNN on two different datasets: FBFans and CreateDebate. FBFans is a privately-owned, single-topic, Chinese, unbalanced, social media dataset, and CreateDebate is a public, multiple-topic, English, balanced, forum dataset. Results using these two datasets show the applicability and superiority for different topics, languages, data distributions, and platforms.\nThe FBFans dataset contains data from anti-nuclear-power Chinese Facebook fan groups from September 2013 to August 2014, including posts and their author and liker IDs. There are a total of 2,496 authors, 505,137 likers, 33,686 commenters, and 505,412 unique users. Two annotators were asked to take into account only the post content to label the stance of the posts in the whole dataset as supportive, neutral, or unsupportive (hereafter denoted as Sup, Neu, and Uns). Sup/Uns posts were those in support of or against anti-reconstruction; Neu posts were those evincing a neutral standpoint on the topic, or were irrelevant. Raw agreement between annotators is 0.91, indicating high agreement. Specifically, Cohen’s Kappa for Neu and not Neu labeling is 0.58 (moderate), and for Sup or Uns labeling is 0.84 (almost perfect). Posts with inconsistent labels were filtered out, and the development and testing sets were randomly selected from what was left. Posts in the development and testing sets involved at least one user who appeared in the training set. The number of posts for each stance is shown on the left-hand side of Table TABREF12 . About twenty percent of the posts were labeled with a stance, and the number of supportive (Sup) posts was much larger than that of the unsupportive (Uns) ones: this is thus highly skewed data, which complicates stance classification. On average, 161.1 users were involved in one post. The maximum was 23,297 and the minimum was one (the author). For comments, on average there were 3 comments per post. The maximum was 1,092 and the minimum was zero.\nTo test whether the assumption of this paper – posts attract users who hold the same stance to like them – is reliable, we examine the likes from authors of different stances. Posts in FBFans dataset are used for this analysis. We calculate the like statistics of each distinct author from these 32,595 posts. As the numbers of authors in the Sup, Neu and Uns stances are largely imbalanced, these numbers are normalized by the number of users of each stance. Table TABREF13 shows the results. Posts with stances (i.e., not neutral) attract users of the same stance. Neutral posts also attract both supportive and neutral users, like what we observe in supportive posts, but just the neutral posts can attract even more neutral likers. These results do suggest that users prefer posts of the same stance, or at least posts of no obvious stance which might cause annoyance when reading, and hence support the user modeling in our approach.\nThe CreateDebate dataset was collected from an English online debate forum discussing four topics: abortion (ABO), gay rights (GAY), Obama (OBA), and marijuana (MAR). The posts are annotated as for (F) and against (A). Replies to posts in this dataset are also labeled with stance and hence use the same data format as posts. The labeling results are shown in the right-hand side of Table TABREF12 . We observe that the dataset is more balanced than the FBFans dataset. In addition, there are 977 unique users in the dataset. To compare with Hasan and Ng's work, we conducted five-fold cross-validation and present the annotation results as the average number of all folds BIBREF9 , BIBREF5 .\nThe FBFans dataset has more integrated functions than the CreateDebate dataset; thus our model can utilize all linguistic and extra-linguistic features.

        "answer": "Yes, it does.",
        "evidence": "Understanding what people are talking about and how they feel about it is valuable especially for industries which need to know the customers' opinions on their products. Aspect-Based Sentiment Analysis (ABSA) is a branch of sentiment analysis which deals with extracting the opinion targets (aspects) as well as the sentiment expressed towards them. For instance, in the sentence The spaghetti was out of this world., a positive sentiment is mentioned towards the target which is spaghetti. Performing these tasks requires a deep understanding of the language. Traditional machine learning methods such as SVM BIBREF2, Naive Bayes BIBREF3, Decision Trees BIBREF4, Maximum Entropy BIBREF5 have long been practiced to acquire such knowledge. However, in recent years due to the abundance of available data and computational power, deep learning methods such as CNNs BIBREF6, BIBREF7, BIBREF8, RNNs BIBREF9, BIBREF10, BIBREF11, and the Transformer BIBREF12 have outperformed the traditional machine learning techniques in various tasks of sentiment analysis. Bidirectional Encoder Representations from Transformers (BERT) BIBREF13 is a deep and powerful language model which uses the encoder of the Transformer in a self-supervised manner to learn the language model. It has been shown to result in state-of-the-art performances on the GLUE benchmark BIBREF14 including text classification. BIBREF1 show that adding domain-specific information to this model can enhance its performance in ABSA. Using their post-trained BERT (BERT-PT), we add adversarial examples to further improve BERT's performance on Aspect Extraction (AE) and Aspect Sentiment Classification (ASC) which are two major tasks in ABSA. A brief overview of these two sub-tasks is given in Section SECREF3.\nAdversarial examples are a way of fooling a neural network to behave incorrectly BIBREF15. They are created by applying small perturbations to the original inputs. In the case of images, the perturbations can be invisible to human eye, but can cause neural networks to output a completely different response from the true one. Since neural nets make mistakes on these examples, introducing them to the network during the training can improve their performance. This is called adversarial training which acts as a regularizer to help the network generalize better BIBREF0. Due to the discrete nature of text, it is not feasible to produce perturbed examples from the original inputs. As a workaround, BIBREF16 apply this technique to the word embedding space for text classification. Inspired by them and building on the work of BIBREF1, we experiment with adversarial training for ABSA.\nOur contributions are twofold. First, by carrying out an ablation study on the number of training epochs and the values for dropout in the classification layer, we show that there are values that outperform the specified ones for BERT-PT. Second, we introduce the application of adversarial training in ABSA by proposing a novel architecture which combines adversarial training with the BERT language model for AE and ASC tasks. Our experiments show that the proposed model outperforms the best performance of BERT-PT in both tasks.\nOur experiments show that the proposed model outperforms the best performance of BERT-PT in both tasks.",

        "evidence": "“Ché saetta previsa vien più lenta.”\n\n– Dante Alighieri, Divina Commedia, Paradiso\nAntisocial behavior is a persistent problem plaguing online conversation platforms; it is both widespread BIBREF0 and potentially damaging to mental and emotional health BIBREF1, BIBREF2. The strain this phenomenon puts on community maintainers has sparked recent interest in computational approaches for assisting human moderators.\nPrior work in this direction has largely focused on post-hoc identification of various kinds of antisocial behavior, including hate speech BIBREF3, BIBREF4, harassment BIBREF5, personal attacks BIBREF6, and general toxicity BIBREF7. The fact that these approaches only identify antisocial content after the fact limits their practicality as tools for assisting pre-emptive moderation in conversational domains.\nAddressing this limitation requires forecasting the future derailment of a conversation based on early warning signs, giving the moderators time to potentially intervene before any harm is done (BIBREF8 BIBREF8, BIBREF9 BIBREF9, see BIBREF10 BIBREF10 for a discussion). Such a goal recognizes derailment as emerging from the development of the conversation, and belongs to the broader area of conversational forecasting, which includes future-prediction tasks such as predicting the eventual length of a conversation BIBREF11, whether a persuasion attempt will eventually succeed BIBREF12, BIBREF13, BIBREF14, whether team discussions will eventually lead to an increase in performance BIBREF15, or whether ongoing counseling conversations will eventually be perceived as helpful BIBREF16.\nApproaching such conversational forecasting problems, however, requires overcoming several inherent modeling challenges. First, conversations are dynamic and their outcome might depend on how subsequent comments interact with each other. Consider the example in Figure FIGREF2: while no individual comment is outright offensive, a human reader can sense a tension emerging from their succession (e.g., dismissive answers to repeated questioning). Thus a forecasting model needs to capture not only the content of each individual comment, but also the relations between comments. Previous work has largely relied on hand-crafted features to capture such relations—e.g., similarity between comments BIBREF16, BIBREF12 or conversation structure BIBREF17, BIBREF18—, though neural attention architectures have also recently shown promise BIBREF19.\nThe second modeling challenge stems from the fact that conversations have an unknown horizon: they can be of varying lengths, and the to-be-forecasted event can occur at any time. So when is it a good time to make a forecast? Prior work has largely proposed two solutions, both resulting in important practical limitations. One solution is to assume (unrealistic) prior knowledge of when the to-be-forecasted event takes place and extract features up to that point BIBREF20, BIBREF8. Another compromising solution is to extract features from a fixed-length window, often at the start of the conversation BIBREF21, BIBREF15, BIBREF16, BIBREF9. Choosing a catch-all window-size is however impractical: short windows will miss information in comments they do not encompass (e.g., a window of only two comments would miss the chain of repeated questioning in comments 3 through 6 of Figure FIGREF2), while longer windows risk missing the to-be-forecasted event altogether if it occurs before the end of the window, which would prevent early detection.\nIn this work we introduce a model for forecasting conversational events that overcomes both these inherent challenges by processing comments, and their relations, as they happen (i.e., in an online fashion). Our main insight is that models with these properties already exist, albeit geared toward generation rather than prediction: recent work in context-aware dialog generation (or “chatbots”) has proposed sequential neural models that make effective use of the intra-conversational dynamics BIBREF22, BIBREF23, BIBREF24, while concomitantly being able to process the conversation as it develops (see BIBREF25 for a survey).\nIn order for these systems to perform well in the generative domain they need to be trained on massive amounts of (unlabeled) conversational data. The main difficulty in directly adapting these models to the supervised domain of conversational forecasting is the relative scarcity of labeled data: for most forecasting tasks, at most a few thousands labeled examples are available, insufficient for the notoriously data-hungry sequential neural models.\nTo overcome this difficulty, we propose to decouple the objective of learning a neural representation of conversational dynamics from the objective of predicting future events. The former can be pre-trained on large amounts of unsupervised data, similarly to how chatbots are trained. The latter can piggy-back on the resulting representation after fine-tuning it for classification using relatively small labeled data. While similar pre-train-then-fine-tune approaches have recently achieved state-of-the-art performance in a number of NLP tasks—including natural language inference, question answering, and commonsense reasoning (discussed in Section SECREF2)—to the best of our knowledge this is the first attempt at applying this paradigm to conversational forecasting.\nTo test the effectiveness of this new architecture in forecasting derailment of online conversations, we develop and distribute two new datasets. The first triples in size the highly curated `Conversations Gone Awry' dataset BIBREF9, where civil-starting Wikipedia Talk Page conversations are crowd-labeled according to whether they eventually lead to personal attacks; the second relies on in-the-wild moderation of the popular subreddit ChangeMyView, where the aim is to forecast whether a discussion will later be subject to moderator action due to “rude or hostile” behavior. In both datasets, our model outperforms existing fixed-window approaches, as well as simpler sequential baselines that cannot account for inter-comment relations. Furthermore, by virtue of its online processing of the conversation, our system can provide substantial prior notice of upcoming derailment, triggering on average 3 comments (or 3 hours) before an overtly toxic comment is posted.\nTo summarize, in this work we:\nintroduce the first model for forecasting conversational events that can capture the dynamics of a conversation as it develops;\nbuild two diverse datasets (one entirely new, one extending prior work) for the task of forecasting derailment of online conversations;\ncompare the performance of our model against the current state-of-the-art, and evaluate its ability to provide early warning signs.\nOur work is motivated by the goal of assisting human moderators of online communities by preemptively signaling at-risk conversations that might deserve their attention. However, we caution that any automated systems might encode or even amplify the biases existing in the training data BIBREF26, BIBREF27, BIBREF28, so a public-facing implementation would need to be exhaustively scrutinized for such biases BIBREF29.\n\nOur main insight is that models with these properties already exist, albeit geared toward generation rather than prediction: recent work in context-aware dialog generation (or “chatbots”) has proposed sequential neural models that make effective use of the intra-conversational dynamics, while concomitantly being able to process the conversation as it develops (see for a survey).",

Fake news is misinformation masked under the guise of a real news article, and is used to deceptively influence people’s beliefs.\nFor this report, we are classifying news articles as “real” or “fake”, which will be a binary classification problem - classifying the samples as a positive (with fake news) or negative (not fake news) sample. Many studies have used machine learning algorithms and build classifiers based on features like content, the author’s name and job-title, using lots of models like the convolutional neural network (CNN), recurrent neural network (RNN), feed-forward neural network (FFNN), long-short term memory (LSTM) and logistic regression to find the most optimal model and return its results. In [1], the author built a classifier using natural language processing and used models like CNN, RNN, FFNN, and Logistic Regression and concluded that the CNN classifiers could not be as competitive as the RNN classifiers. The authors in [2] think that their study can be improved by having more features like knowing the history of lies spoken by the news reporter or the speaker.\nMoreover, apart from the traditional machine learning methods, new models have also been developed. One of the newer models, TraceMiner, creates an LSTM-RNN model inferring from the embedding of social media users in the social network structure to propagate through the path of messages and has provided high classification accuracy$^{5}$. FAKEDETECTOR is another inference model developed to detect the credibility of the fake news which is considered to be quite reliable and accurate$^{7}$.\nThere also have been studies that have a different approach. A paper surveys the current state-of-the-art technologies that are imperative when adopting and developing fake news detection and provides a classification of several accurate assessment methods that analyze the text and detect anomalies$^{3}$.\nThese previous approaches lack a clear contextual analysis used in NLP. We considered the semantic meaning of each word and we feel that the presence of particular words influence the meaning. We reckoned this important since we felt the contextual meaning of the text needs to be preserved and analyzed for better classification. Other studies emphasize the user and features related to them. In [4], “45 features…[were used] for predicting accuracy...across four types: structural, user, content, and temporal,” so features included characteristics beyond the text. Article [6] \"learn[s] the representations of news articles, creators and subjects simultaneously.\" In our project, we emphasize the content by working with articles whose labels only relate to the text, nothing outside that scope, and have used SVM, Logistic Regression, ANN, LSTM, and Random Forest.\nWe had devised this problem into 3 different phases: pre-processing, text-to-numeric representation conversion using pre-trained algorithms, and then evaluate the models using state-of-the-art machine learning algorithms. We had analysed the data set and in particular the text part of the data explaining how it is distributed and then we converted each text into numeric representation using pre-training models such as TFIDF, CV and W2V for vector representation. Finally, we evaluated our numeric conversion data using significant machine learning algorithms such as neural networks, classification algorithms etc to perform the classification.\nFake news is misinformation masked under the guise of a real news article, and is used to deceptively influence people’s beliefs.",

The results of the regression tasks are reported in Tables TABREF25 and TABREF29 in terms of the mean absolute error between the predicted and actual scores, as well as the Spearman INLINEFORM0 correlation between the rankings induced by both sets of scores. It can be clearly seen from the results that our proposed method (EGEL-All) can effectively integrate Flickr tags with the available structured information. It outperforms the baselines for all the considered tasks. Furthermore, note that the PPMI-based weighting in EGEL-Tags consistently outperforms GloVe and that both the addition of negative examples and term selection lead to further improvements. The use of term selection leads to particularly substantial improvements for the regression problems.\nWhile our experimental results confirm the usefulness of embeddings for predicting environmental features, this is only consistently the case for the variants that use both the tags and the structured datasets. In particular, comparing BOW-Tags with EGEL-Tags, we sometimes see that the former achieves the best results. While this might seem surprising, it is in accordance with the findings in BIBREF54 , BIBREF38 , among others, where it was also found that bag-of-words representations can sometimes lead to surprisingly effective baselines. Interestingly, we note that in all cases where EGEL-KL(Tags+NS) performs worse than BOW-Tags, we also find that BOW-KL(Tags) performs worse than BOW-Tags. This suggests that for these tasks there is a very large variation in the kind of tags that can inform the prediction model, possibly including e.g. user-specific tags. Some of the information captured by such highly specific but rare tags is likely to be lost in the embedding.\nTo further analyze the difference in performance between BoW representations and embeddings, Figure TABREF29 compares the performance of the GloVe model with the bag-of-words model for predicting place scenicness, as a function of the number of tag occurrences at the considered locations.

The effectiveness of our work lies in combining the strengths of both by ensembling natural and robust models into one, with the goal of retaining the accuracy while improving the robustness. The key challenge lies in how these models should be combined, which we address by using robustness as a principled selection (abstain) mechanism. We hypothesize that empirically, the robust inaccurate samples lie in regions that are close by in the learned manifold, thus regularizing them to become even slightly non-robust generalizes well.",
        "evidence": "In recent years, there has been a significant amount of work that studies and improves both adversarial and certified robustness of neural networks. However, currently, there are two key limitations that hinder the wider adoption of robust models in practice.\nExisting Models are Robustly Inaccurate First, despite substantial progress in training robust models, existing works usually only report robust accuracy, i.e., samples for which the model robustly predicts the correct label. Meanwhile, the issue of robust inaccuracy, i.e., samples that are robustly misclassified with a wrong label, is usually not even reported (we formally define robust inaccuracy in Equation). This is especially problematic for safety-critical models, where the robustness can be mistakenly used as a safety argument. We quantify the severity of this issue in Table, by evaluating recent state-of-the-art robust models. As can be seen, recent models contain up to 15% of robust inaccurate samples and the ratio of such samples worsens with smaller perturbation regions. Table: Percentage of robust and inaccurate samples for various recent robust models and datasets, which we describe in more detail in Section 7. Each model is trained for the indicated threat model and evaluated using 40-step APGD ., and our training L ERA (Equation). In this case, our training achieves the same robust accuracy as L TRADES but avoids all robust inaccurate samples by making them non-robust. Note that all three models predict over all three classes, however, the decision regions for class 2 of the L TRADES and L ERA trained models happen to be too small to be visible. The considered model architecture and the training hyperparameters are provided in Appendix A.2.\nRobustness vs Accuracy Tradeoff Second, existing robust training methods improve the model robustness, but they also typically degrade the standard accuracy on unperturbed inputs. To address this limitation, a number of recent works study this issue in detail and propose new methods to mitigate it.\nIn this work, we advance the line of work that aims to boost robustness without sacrificing accuracy, but we approach the problem from a new perspective -by avoiding robust inaccuracy.\nConcretely, we propose a new training method that jointly maximizes robust accuracy while minimizing robust inaccuracy. We illustrate the effect of our training on a synthetic dataset (described in Appendix A.2) in Figure, showing the decision boundaries of three models, trained using standard training L std , adversarial training L TRADES, and our training L ERA (Equation). First, observe that while the L std trained model achieves 100% accuracy, only 91.1% of these samples are robust (and accurate). When using L TRADES , we can observe the robustness vs accuracy tradeoffthe robust accuracy improves to 98.4% at the expense of 1.6% (robust) inaccuracy. In contrast, using our L ERA , we retain the high robust accuracy of 98.4% but avoid all robust inaccurate samples by appropriately shifting the decision boundary, rendering them non-robust.\nSecond, since our models are trained to be robust only if they are accurate, we leverage robustness as a principled abstain mechanism. This abstain mechanism then allows us to combine models in a compositional architecture that significantly boosts overall robustness without sacrificing accuracy. Concretely, in Figure, we would define a selector model that abstains on all non-robust samples. Then, the abstained (non-robust) samples are evaluated by the standard trained model L std , while the selected samples are evaluated using the robust model L ERA . This allows us to achieve the best of both models -high robust accuracy (98.4%), high natural accuracy (100%), and no robust inaccuracy.\nWe show the practical effectiveness of our approach by instantiating over several datasets and existing robust models for both empirical and certified robustness. Our evaluations show that our method effectively reduces robust and inaccurate samples by up to 97.28%. Further, our approach significantly improves robustness for CIFAR-10, CIFAR-100, MTSD and SBB datasets by 60.3%, 38.8%, 29.2% and 37.7%, respectively, while simultaneously decreasing natural accuracy by only 0.2%.\nFigure 1: Decision regions for models trained via standard training Lstd, adversarial training LTRADES (Zhang et al., 2019a), and our training LERA (Equation 5). In this case, our training achieves the same robust accuracy as LTRADES but avoids all robust inaccurate samples by making them non-robust. Note that all three models predict over all three classes, however, the decision regions for class 2 of the LTRADES and LERA trained models happen to be too small to be visible.

        "evidence": "Sarcasm, in general, has been the focus of research for quite some time. In one of the pioneering works jorgensen1984test explained how sarcasm arises when a figurative meaning is used opposite to the literal meaning of the utterance. In the word of clark1984pretense, sarcasm processing involves canceling the indirectly negated message and replacing it with the implicated one. giora1995irony, on the other hand, define sarcasm as a mode of indirect negation that requires processing of both negated and implicated messages. ivanko2003context define sarcasm as a six tuple entity consisting of a speaker, a listener, Context, Utterance, Literal Proposition and Intended Proposition and study the cognitive aspects of sarcasm processing.\nComputational linguists have previously addressed this problem using rule based and statistical techniques, that make use of : (a) Unigrams and Pragmatic features BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 (b) Stylistic patterns BIBREF4 and patterns related to situational disparity BIBREF5 and (c) Hastag interpretations BIBREF6 , BIBREF7 .\nMost of the previously done work on sarcasm detection uses distant supervision based techniques (ex: leveraging hashtags) and stylistic/pragmatic features (emoticons, laughter expressions such as “lol” etc). But, detecting sarcasm in linguistically well-formed structures, in absence of explicit cues or information (like emoticons), proves to be hard using such linguistic/stylistic features alone.\nWith the advent of sophisticated eye-trackers and electro/magneto-encephalographic (EEG/MEG) devices, it has been possible to delve deep into the cognitive underpinnings of sarcasm understanding. Filik2014, using a series of eye-tracking and EEG experiments try to show that for unfamiliar ironies, the literal interpretation would be computed first. They also show that a mismatch with context would lead to a re-interpretation of the statement, as being ironic. Camblin2007103 show that in multi-sentence passages, discourse congruence has robust effects on eye movements. This also implies that disrupted processing occurs for discourse incongruent words, even though they are perfectly congruous at the sentence level. In our previous work BIBREF8 , we augment cognitive features, derived from eye-movement patterns of readers, with textual features to detect whether a human reader has realized the presence of sarcasm in text or not.\nThe recent advancements in the literature discussed above, motivate us to explore gaze-based cognition for sarcasm detection.

        "evidence": "The prevalent use of emoji—and their text-based precursors—is mostly unaddressed in current natural language processing (NLP) tasks. The support of the Unicode Standard BIBREF0 for emoji characters in 2010 ushered in a wide-spread, international adoption of these graphical elements in casual contexts. Interpreting the meaning of these characters has been challenging however, since they take on multiple semantic roles BIBREF1.\nWhether or not emoji are used depends on the context of a text or conversation, with more formal settings generally being less tolerating. So is the popular aligned corpus Europarl BIBREF2 naturally devoid of emoji. Technical limitations, like no Unicode support, also limit its use. This in turn affects commonly used corpora, tokenizers, and pre-trained networks.\nTake for example the Ubuntu Dialog Corpus by BIBREF3, a commonly used corpus for multi-turn systems. This dataset was collected from an Internet Relay Chat (IRC) room casually discussing the operating system Ubuntu. IRC nodes usually support the ASCII text encoding, so there's no support for graphical emoji. However, in the 7,189,051 utterances, there are only 9946 happy emoticons (i.e. :-) and the cruelly denosed :) version) and 2125 sad emoticons.\nWord embeddings are also handling emoji poorly: Word2vec BIBREF4 with the commonly used pre-trained Google News vectors doesn't support the graphical emoji at all and vectors for textual emoticons are inconsistent. As another example with contextualized word embeddings, there are also no emoji or textual emoticons in the vocabulary list of BERT BIBREF5 by default and support for emoji is only recently added to the tokenizer. The same is true for GPT-2 BIBREF6. As all downstream systems, ranging from multilingual résumé parsing to fallacy detection BIBREF7, rely on the completeness of these embeddings, this lack of emoji support can affect the performance of some of these systems.\nAnother challenge is that emoji usage isn't static. Think of shifting conventions, different cultures, and newly added emoji to the Unicode list. Several applications also use their own custom emoji, like chat application Slack and streaming service Twitch. This becomes an issue for methods that leverage the Unicode description BIBREF8 or that rely on manual annotations BIBREF9.\nOur contribution with this paper is two-fold: firstly, we argue that the current use—or rather non-existing use—of emoji in the tokenizing, training, and the datasets themselves is insufficient. Secondly, we attempt to quantify the significance of incorporating emoji-based features by presenting a fine-tuned model. We then compare this model to a baseline, but without special attention to emoji.\nSection SECREF2 will start with an overview of work on emoji representations, emoji-based models and analysis of emoji usage. A brief introduction in conversational systems will also be given. Section SECREF3 will then look into popular datasets with and without emoji and then introduce the dataset we used.\nOur model will then be discussed in Section SECREF4, including the tokenization in Subsection SECREF4, training setup in Subsection SECREF6 and evaluation in Subsection SECREF10. This brings us to the results of our experiment, which is discussed in Section SECREF5 and finally our conclusion and future work are presented in Section SECREF6.\nSecondly, we attempt to quantify the significance of incorporating emoji-based features by presenting a fine-tuned model.",

        "answer": "To achieve a high precision, to minimize wasting crowd effort when their efforts will be redundant, and a high recall, to avoid missing out on collecting the diversity of accepted answers from a crowd.",
        "evidence": "We now describe our studies to assess the predictive power of our classification systems to decide whether visual questions will lead to answer (dis)agreement.\nWe capitalize on today's largest visual question answering dataset BIBREF2 to evaluate our prediction system, which includes 369,861 visual questions about real images. Of these, 248,349 visual questions (i.e., Training questions 2015 v1.0) are kept for for training and the remaining 121,512 visual questions (i.e., Validation questions 2015 v1.0) are employed for testing our classification system. This separation of training and testing samples enables us to estimate how well a classifier will generalize when applied to an unseen, independent set of visual questions.\nTo our knowledge, no prior work has directly addressed predicting answer (dis)agreement for visual questions. Therefore, we employ as a baseline a related VQA algorithm BIBREF24 , BIBREF2 which produces for a given visual question an answer with a confidence score. This system parallels the deep learning architecture we adapt. However, it predicts the system's uncertainty in its own answer, whereas we are interested in the humans' collective disagreement on the answer. Still, it is a useful baseline to see if an existing algorithm could serve our purpose.\nWe evaluate the predictive power of the classification systems based on each classifier's predictions for the 121,512 visual questions in the test dataset. We first show performance of the baseline and our two prediction systems using precision-recall curves. The goals are to achieve a high precision, to minimize wasting crowd effort when their efforts will be redundant, and a high recall, to avoid missing out on collecting the diversity of accepted answers from a crowd. We also report the average precision (AP), which indicates the area under a precision-recall curve. AP values range from 0 to 1 with better-performing prediction systems having larger values.\nFigure FIGREF8 a shows precision-recall curves for all prediction systems. Both our proposed classification systems outperform the VQA Algorithm BIBREF2 baseline; e.g., Ours - RF yields a 12 percentage point improvement with respect to AP. This is interesting because it shows there is value in learning the disagreement task specifically, rather than employing an algorithm's confidence in its answers. More generally, our results demonstrate it is possible to predict whether a crowd will agree on a single answer from a given image and associated question. Despite the significant variety of questions and image content, and despite the variety of reasons for which the crowd can disagree, our learned model is able to produce quite accurate results.\nWe observe our Random Forest classifier outperforms our deep learning classifier; e.g., Ours: RF yields a three percentage point improvement with respect to AP while consistently yielding improved precision-recall values over Ours: LSTM-CNN (Figure FIGREF8 a). In general, deep learning systems hold promise to replace handcrafted features to pick out the discriminative features. Our baselines highlight a possible value in developing a different deep learning architecture for the problem of learning answer disagreement than applied for predicting answers to visual questions.\nWe show examples of prediction results where our top-performing RF classifier makes its most confident predictions (Figure FIGREF8 b). In these examples, the predictor expects human agreement for “what room... ?\" visual questions and disagreement for “why... ?\" visual questions. These examples highlight that the classifier may have a strong language prior towards making predictions, as we will discuss in the next section.\nWe now explore what makes a visual question lead to crowd answer agreement versus disagreement. We examine the influence of whether visual questions lead to the three types of answers (“yes/no\", “number\", “other\") for both our random forest (RF) and deep learning (DL) classification systems. We enrich our analysis by examining the predictive performance of both classifiers when they are trained and tested exclusively with image and question features respectively. Figure FIGREF9 shows precision-recall curves for both classification systems with question features alone (Q), image features alone (I), and both question and image features together (Q+I).\nWhen comparing AP scores (Figure FIGREF9 ), we observe our Q+I predictors yield the greatest predictive performance for visual questions that lead to “other\" answers, followed by “number\" answers, and finally “yes/no\" answers. One possible reason for this finding is that the question wording strongly drives whether a crowd will disagree for “other\" visual questions, whereas some notion of common sense may be required to learn whether a crowd will agree for “yes/no\" visual questions (e.g., Figure FIGREF7 a vs Figure FIGREF7 g).\nWe observe that question-based features yield greater predictive performance than image-based features for all visual questions, when comparing AP scores for Q and I classification results (Figure FIGREF9 ). In fact, image features contribute to performance improvements only for our random forest classifier for visual questions that lead to “number\" answers, as illustrated by comparing AP scores for Our RF: Q+I and Our RF: Q (Figure FIGREF9 b). Our overall finding that most of the predictive power stems from language-based features parallels feature analysis findings in the automated VQA literature BIBREF2 , BIBREF21 . This does not mean, however, that the image content is not predictive. Further work improving visual content cues for VQA agreement is warranted.\nOur findings suggest that our Random Forest classifier's overall advantage over our deep learning system arises because of counting questions, as indicated by higher AP scores (Figure FIGREF9 ). For example, the advantage of the initial higher precision (Figure FIGREF8 a; Ours: RF vs Ours: DL) is also observed for counting questions (Figure FIGREF9 b; Ours: RF - Q+I vs Ours: DL - Q+I). We hypothesize this advantage arises due to the strength of the Random Forest classifier in pairing the question prior (“How many?\") with the image-based SOS features that indicates the number of objects in an image. Specifically, we expect “how many\" to lead to agreement only for small counting problems.\nClassification Performance: We evaluate the predictive power of the classification systems based on each classifier’s predictions for the 121,512 visual questions in the test dataset. We first show performance of the baseline and our two prediction systems using precision-recall curves. The goals are to achieve a high precision, to minimize wasting crowd effort when their efforts will be redundant, and a high recall, to avoid missing out on collecting the diversity of accepted answers from a crowd.

        "answer": "The changing landscape of Victorian scientific culture.",
        "evidence": "We typically start by identifying the questions we wish to explore. Can text analysis provide a new perspective on a “big question” that has been attracting interest for years? Or can we raise new questions that have only recently emerged, for example about social media? For social scientists working in computational analysis, the questions are often grounded in theory, asking: How can we explain what we observe? These questions are also influenced by the availability and accessibility of data sources. For example, the choice to work with data from a particular social media platform may be partly determined by the fact that it is freely available, and this will in turn shape the kinds of questions that can be asked. A key output of this phase are the concepts to measure, for example: influence; copying and reproduction; the creation of patterns of language use; hate speech. Computational analysis of text motivated by these questions is insight driven: we aim to describe a phenomenon or explain how it came about. For example, what can we learn about how and why hate speech is used or how this changes over time? Is hate speech one thing, or does it comprise multiple forms of expression? Is there a clear boundary between hate speech and other types of speech, and what features make it more or less ambiguous? In these cases, it is critical to communicate high-level patterns in terms that are recognizable.\nThis contrasts with much of the work in computational text analysis, which tends to focus on automating tasks that humans perform inefficiently. These tasks range from core linguistically motivated tasks that constitute the backbone of natural language processing, such as part-of-speech tagging and parsing, to filtering spam and detecting sentiment. Many tasks are motivated by applications, for example to automatically block online trolls. Success, then, is often measured by performance, and communicating why a certain prediction was made—for example, why a document was labeled as positive sentiment, or why a word was classified as a noun—is less important than the accuracy of the prediction itself. The approaches we use and what we mean by `success' are thus guided by our research questions.\nDomain experts and fellow researchers can provide feedback on questions and help with dynamically revising them. For example, they may say “we already think we know that”, “that's too naïve”, “that doesn't reflect social reality” (negative); “two major camps in the field would give different answers to that question” (neutral); “we tried to look at that back in the 1960s, but we didn't have the technology” (positive); and “that sounds like something that people who made that archive would love”, “that's a really fundamental question” (very positive).\nSometimes we also hope to connect to multiple disciplines. For example, while focusing on the humanistic concerns of an archive, we could also ask social questions such as “is this archive more about collaborative processes, culture-building or norm creation?” or “how well does this archive reflect the society in which it is embedded?\" BIBREF3 used quantitative methods to tell a story about Darwin's intellectual development—an essential biographical question for a key figure in the history of science. At the same time, their methods connected Darwin's development to the changing landscape of Victorian scientific culture, allowing them to contrast Darwin's “foraging” in the scientific literature of his time to the ways in which that literature was itself produced. Finally, their methods provided a case study, and validation of technical approaches, for cognitive scientists who are interested in how people explore and exploit sources of knowledge.\nQuestions about potential “dual use” may also arise. Returning to our introductory example, BIBREF0 started with a deceptively simple question: if an internet platform eliminates forums for hate speech, does this impact hate speech in other forums? The research was motivated by the belief that a rising tide of online hate speech was (and is) making the internet increasingly unfriendly for disempowered groups, including minorities, women, and LBGTQ individuals. Yet the possibility of dual use troubled the researchers from the onset. Could the methodology be adopted to target the speech of groups like Black Lives Matter? Could it be adopted by repressive governments to minimize online dissent? While these concerns remained, they concluded that hypothetical dual use scenarios did not outweigh the tangible contribution this research could offer towards making the online environment more equal and just.\nMurdock et al. [2017] used quantitative methods to tell a story about Darwin’s intellectual development—an essential biographical question for a key figure in the history of science. At the same time, their methods connected Darwin’s development to the changing landscape of Victorian scientific culture,",

        "evidence": "Subword segmentation has become a standard preprocessing step in many neural approaches to natural language processing (NLP) tasks, e.g Neural Machine Translation (NMT) BIBREF0 and Automatic Speech Recognition (ASR) BIBREF1. Word level modeling suffers from sparse statistics, issues with Out-of-Vocabulary (OOV) words, and heavy computational cost due to a large vocabulary. Word level modeling is particularly unsuitable for morphologically rich languages, but subwords are commonly used for other languages as well. Subword segmentation is best suited for languages with agglutinative morphology.\nWhile rule-based morphological segmentation systems can achieve high quality, the large amount of human effort needed makes the approach problematic, particularly for low-resource languages. The systems are language dependent, necessitating use of multiple tools in multilingual setups. As a fast, cheap and effective alternative, data-driven segmentation can be learned in a completely unsupervised manner from raw corpora. Unsupervised morphological segmentation saw much research interest until the early 2010's; for a survey on the methods, see hammarstrom2011unsupervised. Semi-supervised segmentation with already small amounts of annotated training data was found to improve the accuracy significantly when compared to a linguistic segmentation; see ruokolainen2016comparative for a survey. While this line of research has been continued in supervised and more grammatically oriented tasks BIBREF2, the more recent work on unsupervised segmentation is less focused on approximating a linguistically motivated segmentation. Instead, the aim has been to tune subword segmentations for particular applications. For example, the simple substitution dictionary based Byte Pair Encoding segmentation algorithm BIBREF3, first proposed for NMT by sennrich2015neural, has become a standard in the field. Especially in the case of multilingual models, training a single language-independent subword segmentation method is preferable to linguistic segmentation BIBREF4.\nIn this study, we compare three existing and one novel subword segmentation method, all sharing the use of a unigram language model in a generative modeling framework.

        "answer": "In Biomedical Event Extraction, events generally refer to a change in the state of biological molecules such as proteins and DNA.",
        "evidence": "Event Extraction in the Biomedical domain is a task that has gained more importance recently. Event Extraction goes beyond Relation Extraction. In Biomedical Event Extraction, events generally refer to a change in the state of biological molecules such as proteins and DNA. Generally, it includes detection of targeted event types such as gene expression, regulation, localisation and transcription. Each event type in addition can have multiple arguments that need to be detected. An additional layer of complexity comes from the fact that events can also be arguments of other events, giving rise to a nested structure. This helps to capture the underlying biology better BIBREF1 . Detecting the event type often involves recognising and classifying trigger words. Often, these words are verbs such as “activates”, “inhibits”, “phosphorylation” that may indicate a single, or sometimes multiple event types. In this section, we will discuss some of the successful models for Event Extraction in some detail.\nEvent Extraction gained a lot of interest with the availability of an annotated corpus with the BioNLP'09 Shared Task on Event Extraction BIBREF34 . The task involves prediction of trigger words over nine event types such as expression, transcription, catabolism, binding, etc. given only annotation of named entities (proteins, genes, etc.). For each event, its class, trigger expression and arguments need to be extracted. Since the events can be arguments to other events, the final output in general is a graph representation with events and named entities as nodes, and edges that correspond to event arguments. BIBREF33 present a pipeline based method that is heavily dependent on dependency parsing. Their pipeline approach consists of three steps: trigger detection, argument detection and semantic post-processing. While the first two components are learning based systems, the last component is a rule based system. For the BioNLP'09 corpus, only 5% of the events span multiple sentences. Hence the approach does not get affected severely by considering only single sentences. It is important to note that trigger words cannot simply be reduced to a dictionary lookup. This is because a specific word may belong to multiple classes, or may not always be a trigger word for an event. For example, “activate” is found to not be a trigger word in over 70% of the cases. A multi-class SVM is trained for trigger detection on each token, using a large feature set consisting of semantic and syntactic features. It is interesting to note that the hyperparameters of this classifier are optimised based on the performance of the entire end-to-end system.\nFor the second component to detect arguments, labels for edges between entities must be predicted. For the BioNLP'09 Shared Task, each directed edge from one event node to another event node, or from an event node to a named entity node are classified as “theme”, “cause”, or None. The second component of the pipeline makes these predictions independently. This is also trained using a multi-class SVM which involves heavy use of syntactic features, including the shortest dependency path between the nodes. The authors note that the precision-recall choice of the first component affects the performance of the second component: since the second component is only trained on Gold examples, any error by the first component will lead to a cascading of errors. The final component, which is a semantic post-processing step, consists of rules and heuristics to correct the output of the second component. Since the edge predictions are made independently, it is possible that some event nodes do not have any edges, or have an improper combination of edges. The rule based component corrects these and applies rules to break directed cycles in the graph, and some specific heuristics for different types of events. The final model gives a cumulative F-Score of 52% on the test set, and was the best model on the task.\n BIBREF35 note that previous approaches on the task suffer due to the pipeline nature and the propagation of errors. To counter this, they adopt a joint inference method based on Markov Logic Networks BIBREF36 for the same task on BioNLP'09. The Markov Logic Network jointly predicts whether each token is a trigger word, and if yes, the class it belongs to; for each dependency edge, whether it is an argument path leading to a “theme” or a “cause”. By formulating the Event Extraction problem using an MLN, the approach becomes computationally feasible and only linear in the length of the sentence. They incorporate hard constraints to encode rules such as “an argument path must have an event”, “a cause path must start with a regulation event”, etc. In addition, they also include some domain specific soft constraints as well as some linguistically-motivated context-specific soft constraints. In order to train the MLN, stochastic gradient descent was used. Certain heuristic methods are implemented in order to deal with errors due to syntactic parsing, especially ambiguities in PP-attachment and coordination. Their final system is competitive and comes very close to the system by BIBREF33 with an average F-Score of 50%. To further improve the system, they suggest leveraging additional joint-inference opportunities and integrating the syntactic parser better. Some other more recent models for Biomedical Event Extraction include BIBREF37 , BIBREF38 .\nIn Biomedical Event Extraction, events generally refer to a change in the state of biological molecules such as proteins and DNA.",

QA tasks on images BIBREF0 have been widely studied, but most focused on understanding text documents BIBREF1 . A representative dataset in text QA is SQuAD BIBREF1 , in which several end-to-end neural models have accomplished promising performance BIBREF2 . Although there is a significant progress in machine comprehension (MC) on text documents, MC on spoken content is a much less investigated field. In spoken question answering (SQA), after transcribing spoken content into text by automatic speech recognition (ASR), typical approaches use information retrieval (IR) techniques BIBREF3 to find the proper answer from the ASR hypotheses. One attempt towards QA of spoken content is TOEFL listening comprehension by machine BIBREF4 . TOEFL is an English examination that tests the knowledge and skills of academic English for English learners whose native languages are not English. Another SQA corpus is Spoken-SQuAD BIBREF5 , which is automatically generated from SQuAD dataset through Google Text-to-Speech (TTS) system. Recently ODSQA, a SQA corpus recorded by real speakers, is released BIBREF6 .\nTo mitigate the impact of speech recognition errors, using sub-word units is a popular approach for speech-related downstream tasks. It has been applied to spoken document retrieval BIBREF7 and spoken term detection BIBREF8 The prior work showed that, using phonectic sub-word units brought improvements for both Spoken-SQuAD and ODSQA BIBREF5 .\nInstead of considering sub-word features, this paper proposes a novel approach to mitigate the impact of ASR errors. We consider reference transcriptions and ASR hypotheses as two domains, and adapt the source domain data (reference transcriptions) to the target domain data (ASR hypotheses) by projecting these two domains in the shared common space. Therefore, it can effectively benefit the SQA model by improving the robustness to ASR errors in the SQA model.\nDomain adaptation has been successfully applied on computer vision BIBREF9 and speech recognition BIBREF10 .

        "question": "Is the framework capable of capturing clusters without imposing a priori their number or structure?",
        "answer": "Yes.",
        "evidence": "This work has applied a multiscale graph partitioning algorithm (Markov Stability) to extract content-based clusters of documents from a textual dataset of healthcare safety incident reports in an unsupervised manner at different levels of resolution. The method uses paragraph vectors to represent the records and obtains an ensuing similarity graph of documents constructed from their content. The framework brings the advantage of multi-resolution algorithms capable of capturing clusters without imposing a priori their number or structure. Since different levels of resolution of the clustering can be found to be relevant, the practitioner can choose the level of description and detail to suit the requirements of a specific task.\nOur a posteriori analysis evaluating the similarity against the hand-coded categories and the intrinsic topic coherence of the clusters showed that the method performed well in recovering meaningful categories. The clusters of content capture topics of medical practice, thus providing complementary information to the externally imposed classification categories. Our analysis shows that some of the most relevant and persistent communities emerge because of their highly homogeneous medical content, although they are not easily mapped to the standardised external categories. This is apparent in the medically-based content clusters associated with Labour ward, Pressure ulcer, Chemotherapy, Radiotherapy, among others, which exemplify the alternative groupings that emerge from free text content.\nThe categories in the top level (Level 1) of the pre-defined classification hierarchy are highly diverse in size (as shown by their number of assigned records), with large groups such as `Patient accident', `Medication', `Clinical assessment', `Documentation', `Admissions/Transfer' or `Infrastructure' alongside small, specific groups such as `Aggressive behaviour', `Patient abuse', `Self-harm' or `Infection control'. Our multi-scale partitioning finds corresponding groups in content across different levels of resolution, providing additional subcategories with medical detail within some of the large categories (as shown in Fig. 4 and S1 ). An area of future research will be to confirm if the categories found by our analysis are consistent with a second level in the hierarchy of external categories (Level 2, around 100 categories) that is used less consistently in hospital settings. The use of content-driven classification of reports could also be important within current efforts by the World Health Organisation (WHO) under the framework for the International Classification for Patient Safety (ICPS) BIBREF48 to establish a set of conceptual categories to monitor, analyse and interpret information to improve patient care.\nOne of the advantages of a free text analytical approach is the provision, in a timely manner, of an intelligible description of incident report categories derived directly from the rich description in the 'words' of the reporter themselves. The insight from analysing the free text entry of the person reporting could play a valuable role and add rich information than would have otherwise been obtained from the existing approach of pre-defined classes. Not only could this improve the current state of play where much of the free text of these reports goes unused, but it avoids the fallacy of assigning incidents to a pre-defined category that, through a lack of granularity, can miss an important opportunity for feedback and learning. The nuanced information and classifications extracted from free text analysis thus suggest a complementary axis to existing approaches to characterise patient safety incident reports.\nCurrently, local incident reporting system are used by hospitals to submit reports to the NRLS and require risk managers to improve data quality of reports, due to errors or uncertainty in categorisation from reporters, before submission. The application of free text analytical approaches, like the one we have presented here, has the potential to free up risk managers time from labour-intensive tasks of classification and correction by human operators, instead for quality improvement activities derived from the intelligence of the data itself. Additionally, the method allows for the discovery of emerging topics or classes of incidents directly from the data when such events do not fit the pre-assigned categories by using projection techniques alongside methods for anomaly and innovation detection.\nIn ongoing work, we are currently examining the use of our characterisation of incident reports to enable comparisons across healthcare organisations and also to monitor their change over time. This part of ongoing research requires the quantification of in-class text similarities and to dynamically manage the embedding of the reports through updates and recalculation of the vector embedding. Improvements in the process of robust graph construction are also part of our future work. Detecting anomalies in the data to decide whether newer topic clusters should be created, or providing online classification suggestions to users based on the text they input are some of the improvements we aim to add in the future to aid with decision support and data collection, and to potentially help fine-tune some of the predefined categories of the external classification.\nThe framework brings the advantage of multi-resolution algorithms capable of capturing clusters without imposing a priori their number or structure.",

        "evidence": "Speech-to-Text translation (ST) is essential for a wide range of scenarios: for example in emergency calls, where agents have to respond emergent requests in a foreign language BIBREF0; or in online courses, where audiences and speakers use different languages BIBREF1. To tackle this problem, existing approaches can be categorized into cascaded method BIBREF2, BIBREF3, where a machine translation (MT) model translates outputs of an automatic speech recognition (ASR) system into target language, and end-to-end method BIBREF4, BIBREF5, where a single model learns acoustic frames to target word sequence mappings in one step towards the final objective of interest. Although the cascaded model remains the dominant approach due to its better performance, the end-to-end method becomes more and more popular because it has lower latency by avoiding inferences with two models and rectifies the error propagation in theory.\nSince it is hard to obtain a large-scale ST dataset, multi-task learning BIBREF5, BIBREF6 and pre-training techniques BIBREF7 have been applied to end-to-end ST model to leverage large-scale datasets of ASR and MT. A common practice is to pre-train two encoder-decoder models for ASR and MT respectively, and then initialize the ST model with the encoder of the ASR model and the decoder of the MT model. Subsequently, the ST model is optimized with the multi-task learning by weighing the losses of ASR, MT, and ST. This approach, however, causes a huge gap between pre-training and fine-tuning, which are summarized into three folds:\nSubnet Waste: The ST system just reuses the ASR encoder and the MT decoder, while discards other pre-trained subnets, such as the MT encoder. Consequently, valuable semantic information captured by the MT encoder cannot be inherited by the final ST system.\nRole Mismatch: The speech encoder plays different roles in pre-training and fine-tuning. The encoder is a pure acoustic model in pre-training, while it has to extract semantic and linguistic features additionally in fine-tuning, which significantly increases the learning difficulty.\nNon-pre-trained Attention Module: Previous work BIBREF6 trains attention modules for ASR, MT and ST respectively, hence, the attention module of ST does not benefit from the pre-training.\nTo address these issues, we propose a Tandem Connectionist Encoding Network (TCEN), which is able to reuse all subnets in pre-training, keep the roles of subnets consistent, and pre-train the attention module. Concretely, the TCEN consists of three components, a speech encoder, a text encoder, and a target text decoder. Different from the previous work that pre-trains an encoder-decoder based ASR model, we only pre-train an ASR encoder by optimizing the Connectionist Temporal Classification (CTC) BIBREF8 objective function. In this way, the additional decoder of ASR is not required while keeping the ability to read acoustic features into the source language space by the speech encoder. Besides, the text encoder and decoder can be pre-trained on a large MT dataset. After that, we employ common used multi-task learning method to jointly learn ASR, MT and ST tasks.\nCompared to prior works, the encoder of TCEN is a concatenation of an ASR encoder and an MT encoder and our model does not have an ASR decoder, so the subnet waste issue is solved. Furthermore, the two encoders work at tandem, disentangling acoustic feature extraction and linguistic feature extraction, ensuring the role consistency between pre-training and fine-tuning. Moreover, we reuse the pre-trained MT attention module in ST, so we can leverage the alignment information learned in pre-training.\nSince the text encoder consumes word embeddings of plausible texts in MT task but uses speech encoder outputs in ST task, another question is how one guarantees the speech encoder outputs are consistent with the word embeddings. We further modify our model to achieve semantic consistency and length consistency. Specifically, (1) the projection matrix at the CTC classification layer for ASR is shared with the word embedding matrix, ensuring that they are mapped to the same latent space, and (2) the length of the speech encoder output is proportional to the length of the input frame, so it is much longer than a natural sentence. To bridge the length gap, source sentences in MT are lengthened by adding word repetitions and blank tokens to mimic the CTC output sequences.\nWe conduct comprehensive experiments on the IWSLT18 speech translation benchmark BIBREF1, demonstrating the effectiveness of each component. Our model is significantly better than previous methods by 3.6 and 2.2 BLEU scores for the subword-level decoding and character-level decoding strategies, respectively.\nOur contributions are three-folds: 1) we shed light on why previous ST models cannot sufficiently utilize the knowledge learned from the pre-training process; 2) we propose a new ST model, which alleviates shortcomings in existing methods; and 3) we empirically evaluate the proposed model on a large-scale public dataset.\nOur contributions are three-folds: 1) we shed light on why previous ST models cannot sufficiently utilize the knowledge learned from the pre-training process; 2) we propose a new ST model, which alleviates shortcomings in existing methods; and 3) we empirically evaluate the proposed model on a large-scale public dataset.",

        "question": "What datasets used by them?",
        "answer": "Freebase FB15k and WordNet.",
        "evidence": "We now evaluate LiLi in terms of its predictive performance and strategy formulation abilities.\nData: We use two standard datasets (see Table 4): (1) Freebase FB15k, and (2) WordNet INLINEFORM0 . Using each dataset, we build a fairly large graph and use it as the original KB ( INLINEFORM1 ) for evaluation. We also augment INLINEFORM2 with inverse triples ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ) for each ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) following existing KBC methods.\nParameter Settings. Unless specified, the empirically set parameters (see Table 1) of LiLi are: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 , INLINEFORM4 , INLINEFORM5 , INLINEFORM6 , INLINEFORM7 , INLINEFORM8 , INLINEFORM9 , INLINEFORM10 . For training RL-model with INLINEFORM11 -greedy strategy, we use INLINEFORM12 , INLINEFORM13 , pre-training steps=50000. We used Keras deep learning library to implement and train the prediction model. We set batch-size as 128, max. training epoch as 150, dropout as 0.2, hidden units and embedding size as 300 and learning rate as 5e-3 which is reduced gradually on plateau with factor 0.5 and patience 5. Adam optimizer and early stopping were used in training. We also shuffle INLINEFORM14 in each epoch and adjust class weights inversely proportional to class frequencies in INLINEFORM15 .\nLabeled Dataset Generation and Simulated User Creation. We create a simulated user for each KB to evaluate LiLi. We create the labeled datasets, the simulated user’s knowledge base ( INLINEFORM0 ), and the base KB ( INLINEFORM1 ) from INLINEFORM2 . INLINEFORM3 used as the initial KB graph ( INLINEFORM4 ) of LiLi.\nWe followed BIBREF16 for labeled dataset generation. For Freebase, we found 86 relations with INLINEFORM0 triples and randomly selected 50 from various domains. We randomly shuffle the list of 50 relations, select 25% of them as unknown relations and consider the rest (75%) as known relations. For each known relation INLINEFORM1 , we randomly shuffle the list of distinct triples for INLINEFORM2 , choose 1000 triples and split them into 60% training, 10% validation and 20% test. Rest 10% along with the leftover (not included in the list of 1000) triples are added to INLINEFORM3 . For each unknown relation INLINEFORM4 , we remove all triples of INLINEFORM5 from INLINEFORM6 and add them to INLINEFORM7 . In this process, we also randomly choose 20% triples as test instances for unknown INLINEFORM8 which are excluded from INLINEFORM9 . Note that, now INLINEFORM10 has at least 10% of chosen triples for each INLINEFORM11 (known and unknown) and so, user is always able to provide clues for both cases. For each labeled dataset, we randomly choose 10% of the entities present in dataset triples, remove triples involving those entities from INLINEFORM12 and add to INLINEFORM13 . At this point, INLINEFORM14 gets reduced to INLINEFORM15 and is used as INLINEFORM16 for LiLi. The dataset stats in Table 4 shows that the base KB (60% triples of INLINEFORM17 ) is highly sparse (compared to original KB) which makes the inference task much harder. WordNet dataset being small, we select all 18 relations for evaluation and create labeled dataset, INLINEFORM18 and INLINEFORM19 following Freebase. Although the user may provide clues 100% of the time, it often cannot respond to MLQs and CLQs (due to lack of required triples/facts). Thus, we further enrich INLINEFORM20 with external KB triples.\nGiven a relation INLINEFORM0 and an observed triple ( INLINEFORM1 , INLINEFORM2 , INLINEFORM3 ) in training or testing, the pair ( INLINEFORM4 , INLINEFORM5 ) is regarded as a +ve instance for INLINEFORM6 . Following BIBREF18 , for each +ve instance ( INLINEFORM7 , INLINEFORM8 ), we generate two negative ones, one by randomly corrupting the source INLINEFORM9 , and the other by corrupting the target INLINEFORM10 . Note that, the test triples are not in INLINEFORM11 or INLINEFORM12 and none of the -ve instances overlap with the +ve ones.\nBaselines. As none of the existing KBC methods can solve the OKBC problem, we choose various versions of LiLi as baselines.\nSingle: Version of LiLi where we train a single prediction model INLINEFORM0 for all test relations.\nSep: We do not transfer (past learned) weights for initializing INLINEFORM0 , i.e., we disable LL.\nF-th): Here, we use a fixed prediction threshold 0.5 instead of relation-specific threshold INLINEFORM0 .\nBG: The missing or connecting links (when the user does not respond) are filled with “@-RelatedTo-@\" blindly, no guessing mechanism.\nw/o PTS: LiLi does not ask for additional clues via past task selection for skillset improvement.\nEvaluation Metrics. To evaluate the strategy formulation ability, we introduce a measure called Coverage( INLINEFORM0 ), defined as the fraction of total query data instances, for which LiLi has successfully formulated strategies that lead to winning. If LiLi wins on all episodes for a given dataset, INLINEFORM1 is 1.0. To evaluate the predictive performance, we use Avg. MCC and avg. +ve F1 score.\nWe use two standard datasets (see Table 4): (1) Freebase FB15k12, and (2) WordNet12.",

        "answer": "Dropping source words and repeating words in the generated translation.",
        "evidence": "Neural machine translation (NMT) emerged in the last few years as a very successful paradigm BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . While NMT is generally more fluent than previous statistical systems, adequacy is still a major concern BIBREF4 : common mistakes include dropping source words and repeating words in the generated translation.\nPrevious work has attempted to mitigate this problem in various ways. BIBREF5 incorporate coverage and length penalties during beam search—a simple yet limited solution, since it only affects the scores of translation hypotheses that are already in the beam. Other approaches involve architectural changes: providing coverage vectors to track the attention history BIBREF6 , BIBREF7 , using gating architectures and adaptive attention to control the amount of source context provided BIBREF8 , BIBREF9 , or adding a reconstruction loss BIBREF10 . BIBREF11 also use the notion of fertility implicitly in their proposed model. Their “fertility conditioned decoder” uses a coverage vector and an “extract gate” which are incorporated in the decoding recurrent unit, increasing the number of parameters.\nIn this paper, we propose a different solution that does not change the overall architecture, but only the attention transformation. Namely, we replace the traditional softmax by other recently proposed transformations that either promote attention sparsity BIBREF12 or upper bound the amount of attention a word can receive BIBREF13 . The bounds are determined by the fertility values of the source words. While these transformations have given encouraging results in various NLP problems, they have never been applied to NMT, to the best of our knowledge. Furthermore, we combine these two ideas and propose a novel attention transformation, constrained sparsemax, which produces both sparse and bounded attention weights, yielding a compact and interpretable set of alignments. While being in-between soft and hard alignments (Figure FIGREF20 ), the constrained sparsemax transformation is end-to-end differentiable, hence amenable for training with gradient backpropagation.\nTo sum up, our contributions are as follows:\nWhile NMT is generally more fluent than previous sta-tistical systems, adequacy is still a major concern (Koehn and Knowles, 2017): common mis-takes include dropping source words and repeating words in the generated translation.",

But if either the origin or destination, or both, are far from a subway station, then the total time for the trip may be dominated by the time it takes to get to and from the subway station on either or both ends of the journey; this may add enough time to the time spent on the subway so that the total trip end-to-end takes longer than driving the whole way.",

        "answer": "Retrieval-based chatbots.",
        "evidence": "AliMe Bot is a kind of retrieval-based online service of E-commerce which collects a lot of predefined question-answering pairs. Through data analysis, we find that many variants of a question exist which means a sort of questions can correspond to a same answer. Based on the observation, naturally, we can view these questions with the same answer as a bag. Obviously, the bag contains diverse expressions of a question, which may provide more matching evidence than only one question due to the rich information contained in the bag. Motivated by the fact, different from existing query-question (Q-Q) matching method, we propose a new query-bag matching approach for retrieval-based chatbots. Concretely, when a user raises a query, the query-bag matching model provides the most suitable bag and returns the corresponding answer of the bag. To our knowledge, there is no query-bag matching study exists, and we focus on the new approach in this paper.\nRecalling the text matching task BIBREF0, recently, researchers have adopted the deep neural network to model the matching relationship. ESIM BIBREF1 judges the inference relationship between two sentences by enhanced LSTM and interaction space. SMN BIBREF2 performs the context-response matching for the open-domain dialog system. BIBREF3 BIBREF3 explores the usefulness of noisy pre-training in the paraphrase identification task. BIBREF4 BIBREF4 surveys the methods in query-document matching in web search which focuses on the topic model, the dependency model, etc. However, none of them pays attention to the query-bag matching which concentrates on the matching for a query and a bag containing multiple questions.\nWhen a user poses a query to the bot, the bot searches the most similar bag and uses the corresponding answer to reply to the user. The more information in the query covered by the bag, the more likely the bag's corresponding answer answers the query. What's more, the bag should not have too much information exceeding the query. Thus modelling the bag-to-query and query-to-bag coverage is essential in this task.\nIn this paper, we propose a simple but effective mutual coverage component to model the above-mentioned problem. The coverage is based on the cross-attention matrix of the query-bag pair which indicates the matching degree of elements between the query and bag. The mutual coverage is performed by stacking the cross-attention matrix along two directions, i.e., query and bag, in the word level respectively. In addition to the mutual coverage, a bag representation in word level is issued to help discover the main points of a bag. The bag representation then provides new matching evidence to the query-bag matching model.\nWe conduct experiments on the AliMe and Quora dataset for the query-bag matching based information-seeking conversation. Compared with baselines, we verify the effectiveness of our model. Our model obtains 0.05 and 0.03 $\\text{R}_{10}@1$ gains comparing to the strongest baseline in the two datasets. The ablation study shows the usefulness of the components. The contributions in this paper are summarized as follows: 1) To the best of our knowledge, we are the first to adopt query-bag matching in the information-seeking conversation. 2) We propose the mutual coverage model to measure the information coverage in the query-bag matching. 3) We release the composite Quora dataset to facilitate the research in this area.\nMotivated by the fact, different from existing query-question (Q-Q) matching method, we propose a new query-bag matching approach for retrieval-based chatbots.",

        "question": "What is electric current and how is it measured?",
        "evidence": "The movement of electric charge is known as an electric current, the intensity of which is usually measured in amperes. Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator.\nBy historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current. The motion of negatively charged electrons around an electric circuit, one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of the electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation.\nThe process by which electric current passes through a material is termed electrical conduction, and its nature varies with that of the charged particles and the material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis, where ions (charged atoms) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of a millimetre per second, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.\nIn engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.  If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance. These properties however can become important when circuitry is subjected to transients, such as when first energised.",

The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's conflict with Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic and subjugate all wizards and Muggles (non-magical people). \nThe series follows the life of a boy named Harry Potter. In the first book, Harry Potter and the Philosopher's Stone, Harry lives in a cupboard under the stairs in the house of the Dursleys, his aunt, uncle and cousin, Dudley. The Dursleys consider themselves perfectly normal, but at the age of 11, Harry discovers that he is a wizard. He meets a half-giant named Hagrid who invites him to attend the Hogwarts School of Witchcraft and Wizardry. Harry learns that as a baby, his parents were murdered by the dark wizard Lord Voldemort. When Voldemort attempted to kill Harry, his curse rebounded and Harry survived with a lightning-shaped scar on his forehead.\nHarry becomes a student at Hogwarts and is sorted into Gryffindor House. He gains the friendship of Ron Weasley, a member of a large but poor wizarding family, and Hermione Granger, a witch of non-magical, or Muggle, parentage. Harry encounters the school's potions master, Severus Snape, who displays a dislike for him; the rich pure-blood Draco Malfoy whom he develops an enmity with; and the Defence Against the Dark Arts teacher, Quirinus Quirrell, who turns out to be allied with Lord Voldemort. The first book concludes with Harry's confrontation with Voldemort, who, in his quest to regain a body, yearns to gain the power of the Philosopher's Stone, a substance that bestows everlasting life.",

Each one of these tokenizers, we combine with some types of representation methods, including word to vector methods such as continuous bag of words BIBREF5, pre-trained embedding as fasttext (trained on Wiki Vietnamese language) BIBREF6 and sonvx (trained on Vietnamese newspaper) BIBREF7. Each sentence has a set of words corresponding to a set of word vectors, and that set of word vectors is a representation of a sentence. We also make a sentence embedding by using RoBERTa architecture BIBREF8. CBOW and RoBERTa models trained on text from some resources including VLSP 2016 Sentiment Analysis, VLSP 2018 Sentiment Analysis, VLSP 2019 HSD and text crawled from Facebook. After having sentence representation, we use some classification models to classify input sentences. Those models will be described in detail in the section SECREF13. With the multiply output results, we will use an ensemble method to combine them and output the final result. Ensemble method we use here is Stacking method will be introduced in the section SECREF16.\nThe dataset in this HSD task is really imbalance. Clean class dominates with 91.5%, offensive class takes 5% and the rest belongs to hate class with 3.5%.

Formular DISPLAY_FORM17 is the loss function apply for all models in our system. $w_i$ is the class weight, $y_i$ is the ground truth and $\\hat{y}_i$ is the output of the model.

Whatever the reasons,  the feeling at the end of every night is one of utter exhaustion, where presumably this feeling is now your life, and will be so forever.  But, in that exhaustion, it can be hard to either notice or truly appreciate beautiful little moments simultaneously occurring. For example, you might not pause to appreciate when they laugh at something you say or funny face you make.  Or maybe you miss the beauty in witnessing their frustration and struggle as they persistently try to fit that round peg in the square hole.  Or maybe the way they mispronounce certain words sounds so endearing, though you're more focused on helping them pronounce it correctly.  These are all brief moments where you are witnessing the growth of your child.  These moments are fleeting.  They don't exist forever, because eventually they grow out of them.  They don't find the same jokes or silly faces funny, they figure out the round peg fits in the round hole, and their word pronunciation improves.  And when you notice those are past, you feel nostalgic.  You wish you could relive those moments.  In that nostalgia, you forget about all the exhaustion that came with the territory.

However, a PhD is usually only require in the STEM field for positions that are either focussed on research, such as a research scientist position, or on a specialized field, such as many 'wet labs' in biological research, or more specialized knowledge jobs. Other than these roles, a Master's or other accreditation like professional certificates/MBAs etc. can be used for career advancement. For those interested in an academic career, a PhD is still the fundamental requirement. \n\nIf you do choose to do a PhD, where you do a PhD will influence the amount and type of work that you do. For example, in the EU, the UK, Australia, and some other places, a PhD is usually three years of research with no or minimal extra course work. In the US, though, a PhD typically takes over 4 years and requires the student to take several classes at a graduate level. \nWhile in your program, you will need to spend a lot of time focusing on publication pressures. PhD students, these days, are required to produced 1-3 papers during their PhD in high impact journals.

Many consider a good teacher to be one who is caring, helpful, yet also strict when necessary. \n One book that focuses on what makes a good teacher is Our day out, by Willy Russel. The book provided people in the 1970s with a perspective on what both children and parents were looking for, inspiring many British teachers. According to Russel, a good teacher cares for the learning of their students and demonstrates it. If a teacher does not demonstrate caring behavior, their students will sense it. Carol, one of the students says to Mr.Briggs “Don't lie, you! I know you hate me. I've seen you goin' home in your car, passin' us on the street. You hate all the kids.” (Russell 48). Carol believes that Mr. Briggs does not care about his students, even though he does as shown earlier in the book: “Briggs: What? About you? Listen ... if I didn't care, why am I here, now, trying to stop you doing something stupid.” (Russell 48). Mr Briggs believes that caring for students implies also disciplining them at times. “Listen, I'm not going to spend any more time arguing with you. You may have organized this visit, but I'm the one who's been sent by the Headmaster to supervise. Now, either you take control of the children in your charge or I'll be forced to abandon this visit and order everyone home.” Thus, even if a teacher cares about their students, they should demonstrate it. Opinions from students of different ages will help further illustrate the image of a good teacher. \nMany people think that a good teacher is primarily kind and loving.  However, through multiple interviews it appeared to be only partially true. A good teacher, according to most students, is not overly kind and should apply discipline when needed. For example, 12 year old Monon Mukherjee said that he looks for guidance and ability to teach in a teacher. On the other hand, 40 year old Bilal Aslam looks for discipline and ability to teach. 42 year old Cristian Molina also agrees with the need for discipline, however he also expects teachers to feel an urge to help students no matter who they are. The book and the interviews intersect in many ways. They both highlight the importance of kindness, caring for learning, and teacher’s ability to discipline. However, they also differ in important ways. In the book, teachers were encouraged to be kind and apply discipline when necessary, but through the interviews it has been shown that providing help and guidance are also expected in a good teacher.\nIn conclusion, a good teacher cares about their students' learning, is prepared to help them, yet also disciplines them when necessary. A good teacher should feel an urge to teach students and guide them through the complex path of life.",

        "answer": "A speech-to-text translation system.",
        "evidence": "Typical speech-to-text translation systems pipeline automatic speech recognition (ASR) and machine translation (MT) BIBREF0 . But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT.",

        "question": "From the following passage extract information on how dates were used in the Fertile Crescent.",
        "evidence": "Traditional dried fruit such as raisins, figs, dates, apricots and apples have been a staple of Mediterranean diets for millennia. This is due partly to their early cultivation in the Middle Eastern region known as the Fertile Crescent, made up by parts of modern Iran, Iraq, southwest Turkey, Syria, Lebanon, Palestine, Israel, and northern Egypt. Drying or dehydration also happened to be the earliest form of food preservation: grapes, dates, and figs that fell from the tree or vine would dry in the hot sun. Early hunter-gatherers observed that these fallen fruit took on an edible form, and valued them for their stability as well as their concentrated sweetness. \nThe earliest recorded mention of dried fruits can be found in Mesopotamian tablets dating to about 1500 BC, which contain what are probably the oldest known written recipes. These clay slabs, written in Akkadian, the daily language of Babylonia, were inscribed in cuneiform and tell of diets based on grains (barley, millet, wheat), vegetables and fruits such as dates, figs, apples, pomegranates, and grapes. These early civilizations used dates, date juice evaporated into syrup and raisins as sweeteners. They included dried fruits in their breads for which they had more than 300 recipes, from simple barley bread for the workers to very elaborate, spiced cakes with honey for the palaces and temples.\nThe date palm was one of the first cultivated trees. It was domesticated in Mesopotamia more than 5,000 years ago. It grew abundantly in the Fertile Crescent and it was so productive (an average date palm produces 50 kg (100 lbs) of fruit a year for 60 years or more) that dates were the cheapest of staple foods. Because they were so valuable, they were well recorded in Assyrian and Babylonian monuments and temples. The villagers in Mesopotamia dried them and ate them as sweets. Whether fresh, soft-dried or hard-dried, they helped to give character to meat dishes and grain pies. They were valued by travelers for their energy and were recommended as stimulants against fatigue.\nFigs were also prized in early Mesopotamia, Palestine, Israel, and Egypt where their daily use was probably greater than or equal to that of dates. As well as appearing in wall paintings, many specimens have been found in Egyptian tombs as funerary offerings. In Greece and Crete, figs grew very readily and they were the staple of poor and rich alike, particularly in their dried form.\nGrape cultivation first began in Armenia and the eastern regions of the Mediterranean in the 4th century BC. Raisins were produced by drying grapes in the hot desert sun. Very quickly, viticulture and raisin production spread across northern Africa including Morocco and Tunisia. The Phoenicians and the Egyptians popularized the production of raisins, probably due to the perfect arid environment for sun drying. They put them in jars for storage and allotted them to the different temples by the thousands. They also added them to breads and various pastries, some made with honey, some with milk and eggs.\nFrom the Middle East, these fruits spread through Greece to Italy where they became a major part of the diet. Ancient Romans consumed raisins in spectacular quantities and at all levels of society, including them as a key part of their common meals, along with olives and fresh fruits. Raisined breads were common for breakfast and were consumed with their grains, beans, and cultured milks. Raisins were so valued that they transcended the food realm and became rewards for successful athletes, as well as premium barter currency.\nHaving dried fruits was essential in ancient Rome as these instructions for housekeepers around 100 BC tell: \"She must keep a supply of cooked food on hand for you and the servants. She must keep many hens and have plenty of eggs. She must have a large store of dried pears, sorbs, figs, raisins, sorbs in must, preserved pears and grapes and quinces. She must also keep preserved grapes in grape-pulp and in pots buried in the ground, as well as fresh Praenestine nuts kept in the same way, and Scantian quinces in jars, and other fruits that are usually preserved, as well as wild fruits. All these she must store away diligently every year.\"\nFigs were also extremely popular in Rome. Dried figs were added to bread and formed a major part of the winter food of country people. They were rubbed with spices such as cumin, anise and fennel seeds, or toasted sesame, wrapped in fig leaves and stored in jars. Today, major producing regions include Israel, Jerusalem, Gaza and many other Arabic countries. Dried figs are rich in vitamins, phosphorus and various other important minerals.\nPlums, apricots and peaches had their origins in Asia. They were domesticated in China in the 3rd millennium BC and spread to the Fertile Crescent where they were also very popular, fresh and dried alike. They arrived in Greece and Italy much later and were very expensive but valued in the preparation of gourmet dishes with port or stewed with honey and spices.",

Licence details: http://creativecommons.org/licenses/by/4.0/\nRecent years have seen a surge of interest in automatic keyphrase extraction, thanks to the availability of the SemEval-2010 benchmark dataset BIBREF0 . This dataset is composed of documents (scientific articles) that were automatically converted from PDF format to plain text. As a result, most documents contain irrelevant pieces of text (e.g. muddled sentences, tables, equations, footnotes) that require special handling, so as to not hinder the performance of keyphrase extraction systems. In previous work, these are usually removed at the preprocessing step, but using a variety of techniques ranging from simple heuristics BIBREF1 , BIBREF2 , BIBREF3 to sophisticated document logical structure detection on richly-formatted documents recovered from Google Scholar BIBREF4 . Under such conditions, it may prove difficult to draw firm conclusions about which keyphrase extraction model performs best, as the impact of preprocessing on overall performance cannot be properly quantified.\nWhile previous work clearly states that efficient document preprocessing is a prerequisite for the extraction of high quality keyphrases, there is, to our best knowledge, no empirical evidence of how preprocessing affects keyphrase extraction performance. In this paper, we re-assess the performance of several state-of-the-art keyphrase extraction models at increasingly sophisticated levels of preprocessing. Three incremental levels of document preprocessing are experimented with: raw text, text cleaning through document logical structure detection, and removal of keyphrase sparse sections of the document. In doing so, we present the first consistent comparison of different keyphrase extraction models and study their robustness over noisy text.

Phrases and words are included in the same similarity set if they have the same component word, for example, weapon – nuclear weapon – weapon of mass destruction; discrimination – racial discrimination. It was supposed that if expressions from the same similarity set co-occur in the same document then their contribution into the document's topics is really more than it is presented with their frequencies, therefore their frequencies should be increased. In such an approach, the algorithm can \"see\" similarities between different multiword expressions with the same component word.\nIn our approach, at first, we include related single words and phrases from a thesaurus such as WordNet or EuroVoc in these similarity sets. Then, we add preliminarily extracted ngrams into these sets and, this way, we use two different sources of external knowledge. We use the same LDA-SIM algorithm as described in BIBREF16 but study what types of semantic relations can be introduced into such similarity sets and be useful for improving topic models. The pseudocode of LDA-SIM algorithm is presented in Algorithm SECREF3 , where INLINEFORM0 is a similarity set, expressions in similarity sets can comprise single words, thesaurus phrases or generated noun compounds.\nWe can compare this approach with the approaches applying the generalized Polya urn model BIBREF8 , BIBREF9 , BIBREF10 . To add prior knowledge, those approaches change topic distributions for related words globally in the collection.

        "evidence": "Neural language models BIBREF0 , BIBREF1 , BIBREF2 have become an essential component in several areas of natural language processing (NLP), such as machine translation, speech recognition and image captioning. They have also become a common benchmarking application in machine learning research on recurrent neural networks (RNN), because producing an accurate probabilistic model of human language is a very challenging task which requires all levels of linguistic analysis, from pragmatics to phonology, to be taken into account.\nA typical language model is trained on text in a single language, and if one needs to model multiple languages the standard solution is to train a separate model for each language. This presupposes large quantities of monolingual data in each of the languages that needs to be covered and each model with its parameters is completely independent of any of the other models.\nWe propose instead to use a single model with real-valued vectors to indicate the language used, and to train this model with a large number of languages. We thus get a language model whose predictive distribution INLINEFORM0 is a continuous function of the language vector INLINEFORM1 , a property that is trivially extended to other neural NLP models. In this paper, we explore the “language space” containing these vectors, and in particular explore what happens when we move beyond the points representing the languages of the training corpus.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models. The second motivation is data sparseness, an issue that heavily influences the reliability of data-driven models. Resources are scarce for most languages in the world (and also for most domains in otherwise well-supported languages), which makes it hard to train reasonable parameters. By combining data from many languages, we hope to mitigate this issue.\nIn contrast to related work, we focus on massively multilingual data sets to cover for the first time a substantial amount of the linguistic diversity in the world in a project related to data-driven language modeling. We do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data. The only supervision that is giving during training is a language identifier as a one-hot encoding. From that and the actual training examples, the system learns dense vector representations for each language included in our data set along with the character-level RNN parameters of the language model itself.\nWe do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data.

        "answer": "While art is subjective, there are a few luminary composers who have made significant contributions to musical theatre and whose work has stood the test of time. One could make a case for any of the following. Jerome Kern wrote more than 700 songs and wrote the music to \"Showboat\", one of the first Broadway musicals with a serious plot and themes. The songwriting team of Rogers & Hammerstein was the first to use songs to further the plot vs. break the plot for a song and dance. Their musicals are still enormously popular and performed constantly. They include \"Oklahoma\", \"The King & I\", and \"The Sound of Music\". Leonard Bernstein, while most known for classical music made a major contribution to musicals with the groundbreaking \"West Side Story\", an updated Romeo and Juliet story with spectacular music, every song a classic. Bernstein collaborated with Stephen Sondheim on this musical. Sondheim ushered in the modern-day musical in which shows might explore a theme vs. a linear plot. While he is often criticized for not having \"hummable\" melodies, his genius is undeniable, and he did have one bonafide hit with \"Send in the Clowns\". Jules Styne composed what is often considered the greatest musical of all time, \"Gypsy\". The dynamite songwriting team of John Kander and Fred Ebb composed the longest-running American musical, \"Chicago\" and the dark yet entertaining \"Cabaret\". Finally, while often criticized by musical-theatre purists as blatantly commercial, the success of Andrew Lloyd Webber cannot be denied. He composed the enormously successful \"Cats\", the longest-running Broadway musical of all time \"Phantom of the Opera\" and even into his 80's is still composing, with the recently opened \"Bad Cinderella\" on Broadway.",

The grape most likely gets its name from the French words sauvage (\"wild\") and blanc (\"white\") due to its early origins as an indigenous grape in South West France. It is possibly a descendant of Savagnin. Sauvignon blanc is planted in many of the world's wine regions, producing a crisp, dry, and refreshing white varietal wine. The grape is also a component of the famous dessert wines from Sauternes and Barsac. Sauvignon blanc is widely cultivated in France, Chile, Romania, Canada, Australia, New Zealand, South Africa, Bulgaria, the states of Oregon, Washington, and California in the US. Some New World Sauvignon blancs, particularly from California, may also be called \"Fumé Blanc\", a marketing term coined by Robert Mondavi in reference to Pouilly-Fumé.\n\nDepending on the climate, the flavor can range from aggressively grassy to sweetly tropical. In cooler climates, the grape has a tendency to produce wines with noticeable acidity and \"green flavors\" of grass, green bell peppers and nettles with some tropical fruit (such as passion fruit) and floral (such as elderflower) notes. In warmer climates, it can develop more tropical fruit notes but risks losing much aroma from over-ripeness, leaving only slight grapefruit and tree fruit (such as peach) notes.",

For human content analysis, measures of topic coherence and kernel uniqueness are both important and complement each other. Topics can be coherent but have a lot of repetitions. On the other hand, generated topics can be very diverse, but incoherent within each topic.\nTopic coherence is an automatic metric of interpretability. It was shown that the coherence measure has a high correlation with the expert estimates of topic interpretability BIBREF9 , BIBREF17 . Mimno BIBREF9 described an experiment comparing expert evaluation of LDA-generated topics and automatic topic coherence measures. It was found that most \"bad\" topics consisted of words without clear relations between each other.\nNewman et al. BIBREF6 asked users to score topics on a 3-point scale, where 3=“useful” (coherent) and 1=“useless” (less coherent). They instructed the users that one indicator of usefulness is the ease by which one could think of a short label to describe a topic. Then several automatic measures, including WordNet-based measures and corpus co-occurrence measures, were compared. It was found that the best automatic measure having the largest correlation with human evaluation is word co-occurrence calculated as point-wise mutual information (PMI) on Wikipedia articles. Later Lau et al. BIBREF17 showed that normalized poinwise mutual information (NPMI) BIBREF18 calculated on Wikipedia articles correlates even more strongly with human scores.\nWe calculate automatic topic coherence using two measure variants. The coherence of a topic is the median PMI (NPMI) of word pairs representing the topic, usually it is calculated for INLINEFORM0 most probable elements (in our study ten elements) in the topic. The coherence of the model is the median of the topic coherence. To make this measure more objective, it should be calculated on an external corpus BIBREF17 . In our case, we use Wikipedia dumps. DISPLAYFORM0 \nHuman-constructed topics usually have unique main words. The measure of kernel uniqueness shows to what extent topics are different from each other and is calculated as the number of unique elements among most probable elements of topics (kernels) in relation to the whole number of elements in kernels. DISPLAYFORM0 \nIf uniqueness of the topic kernels is closer to zero then many topics are similar to each other, contain the same words in their kernels. In this paper the kernel of a topic means the ten most probable words in the topic. We also calculated perplexity as the measure of language models. We use it for additional checking the model quality.\nThe coherence of the model is the median of the topic coherence.

        "evidence": "Procrastination is the action of unnecessarily and voluntarily delaying or postponing something despite knowing that there will be negative consequences for doing so. The word has originated from the Latin word procrastinatus, which itself evolved from the prefix pro-, meaning \"forward,\" and crastinus, meaning \"of tomorrow.\" Oftentimes, it is a habitual human behaviour. It is a common human experience involving delay in everyday chores or even putting off salient tasks such as attending an appointment, submitting a job report or academic assignment, or broaching a stressful issue with a partner. Although typically perceived as a negative trait due to its hindering effect on one's productivity often associated with depression, low self-esteem, guilt and inadequacy, it can also be considered a wise response to certain demands that could present risky or negative outcomes or require waiting for new information to arrive.\n\nFrom a cultural and a social perspective, students from both Western and non-Western cultures are found to exhibit academic procrastination, but for different reasons. Students from Western cultures tend to procrastinate in order to avoid doing worse than they have done before or from failing to learn as much as they should have, whereas students from non-Western cultures tend to procrastinate in order to avoid looking incompetent, or to avoid demonstrating a lack of ability in front of their peers. It is also important to consider how different cultural perspectives of time management can impact procrastination. For example, in cultures that have a multi-active view of time, people tend to place a higher value on making sure a job is done accurately before finishing. In cultures with a linear view of time, people tend to designate a certain amount of time on a task and stop once the allotted time has expired.",

In other words, the effect of the mutation is dependent on the genetic background in which it appears. Epistatic mutations therefore have different effects on their own than when they occur together. Originally, the term epistasis specifically meant that the effect of a gene variant is masked by that of a different gene.\n\nThe concept of epistasis originated in genetics in 1907 but is now used in biochemistry, computational biology and evolutionary biology. The phenomenon arises due to interactions, either between genes (such as mutations also being needed in regulators of gene expression) or within them (multiple mutations being needed before the gene loses function), leading to non-linear effects. Epistasis has a great influence on the shape of evolutionary landscapes, which leads to profound consequences for evolution and for the evolvability of phenotypic traits.",

        "answer": "English, French, Spanish, Italian, German, Russian, Chinese and Japanese.",
        "evidence": "There are many tasks in natural language processing which require the classification of sentences or longer paragraphs into a set of predefined categories. Typical applications are for instance topic identification (e.g. sports, news, $\\ldots $ ) or product reviews (positive or negative). There is a large body of research on approaches for document classification. An important aspect to compare these different approaches is the availability of high quality corpora to train and evaluate them. Unfortunately, most of these evaluation tasks focus on the English language only, while there is an ever increasing need to perform document classification in many other languages. One could of course collect and label training data for other languages, but this would be costly and time consuming. An interesting alternative is “cross-lingual document classification”. The underlying idea is to use a representation of the words or whole documents which is independent of the language. By these means, a classifier trained on one language can be transferred to a different one, without the need of resources in that transfer language. Ideally, the performance obtained by cross-lingual transfer should be as close as possible to training the entire system on language specific resources. Such a task was first proposed by BIBREF0 using the Reuters Corpus Volume 2. The aim was to first train a classifier on English and then to transfer it to German, and vice versa. An extension to the transfer between English and French and Spanish respectively was proposed by BIBREF1 . However, only few comparative results are available for these transfer directions.\nThe contributions of this work are as follows. We extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese. For each language, we define a train, development and test corpus. We also provide strong reference results for all transfer directions between the eight languages, e.g. not limited to the transfer between a foreign language and English. We compare two approaches, based either on multilingual word or sentence embeddings respectively. By these means, we hope to define a clear evaluation environment for highly multilingual document classification.\nWe extend previous works and use the data in the Reuters Corpus Volume 2 to define new cross-lingual document classification tasks for eight very different languages, namely English, French, Spanish, Italian, German, Russian, Chinese and Japanese.",

        "evidence": "To assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups, a cleansed version (also called v2) of Reuters Corpus Volume 1 (RCV1) and English Wikipedia. As paragraph vectors can be trained with relatively large vocabularies, we did not perform any stemming of the source text. However, we removed stop words as well as words shorter than two characters and longer than 15 characters. Results reported by BIBREF15 indicate that performance of PV-DBOW can be improved by including n-grams in the model. We therefore evaluated two variants of Binary PV-DBOW: one predicting words in documents and one predicting words and bigrams. Since 20 Newsgroups is a relatively small dataset, we used all words and bigrams from its documents. This amounts to a vocabulary with slightly over one million elements. For the RCV1 dataset we used words and bigrams with at least 10 occurrences in the text, which gives a vocabulary with approximately 800 thousands elements. In case of English Wikipedia we used words and bigrams with at least 100 occurrences, which gives a vocabulary with approximately 1.5 million elements.\nThe 20 Newsgroups dataset comes with reference train/test sets. In case of RCV1 we used half of the documents for training and the other half for evaluation. In case of English Wikipedia we held out for testing randomly selected 10% of the documents. We perform document retrieval by selecting queries from the test set and ordering other test documents according to the similarity of the inferred codes. We use Hamming distance for binary codes and cosine similarity for real-valued representations. Results are averaged over queries. We assess the performance of our models with precision-recall curves and two popular information retrieval metrics, namely mean average precision (MAP) and the normalized discounted cumulative gain at the 10th result (NDCG@10) BIBREF16 . The results depend, of course, on the chosen document relevancy measure. Relevancy measure for the 20 Newsgroups dataset is straightforward: a retrieved document is relevant to the query if they both belong to the same newsgroup. In RCV1 each document belongs to a hierarchy of topics, making the definition of relevancy less obvious. In this case we adopted the relevancy measure used by BIBREF3 . That is, the relevancy is calculated as the fraction of overlapping labels in a retrieved document and the query document. Overall, our selection of test datasets and relevancy measures for 20 Newsgroups and RCV1 follows BIBREF3 , enabling comparison with semantic hashing codes. To assess the relevancy of articles in English Wikipedia we can employ categories assigned to them. However, unlike in RCV1, Wikipedia categories can have multiple parent categories and cyclic dependencies. Therefore, for this dataset we adopted a simplified relevancy measure: two articles are relevant if they share at least one category. We also removed from the test set categories with less than 20 documents as well as documents that were left with no categories. Overall, the relevancy is measured over more than INLINEFORM0 categories, making English Wikipedia harder than the other two benchmarks.\nWe use AdaGrad BIBREF17 for training and inference in all experiments reported in this work. During training we employ dropout BIBREF18 in the embedding layer. To facilitate models with large vocabularies, we approximate the gradients with respect to the softmax logits using the method described by BIBREF9 . Binary PV-DM networks use the same number of dimensions for document codes and word embeddings.\nPerformance of 128- and 32-bit binary paragraph vector codes is reported in Table TABREF8 and in Figure FIGREF7 . For comparison we also report performance of real-valued paragraph vectors. Note that the binary codes perform very well, despite their far lower capacity: on 20 Newsgroups and RCV1 the 128-bit Binary PV-DBOW trained with bigrams approaches the performance of the real-valued paragraph vectors, while on English Wikipedia its performance is slightly lower. Furthermore, Binary PV-DBOW with bigrams outperforms semantic hashing codes: comparison of precision-recall curves from Figures FIGREF7 a and FIGREF7 b with BIBREF3 shows that 128-bit codes learned with this model outperform 128-bit semantic hashing codes on 20 Newsgroups and RCV1. Moreover, the 32-bit codes from this model outperform 128-bit semantic hashing codes on the RCV1 dataset, and on the 20 Newsgroups dataset give similar precision up to approximately 3% recall and better precision for higher recall levels. Note that the difference in this case lies not only in retrieval precision: the short 32-bit Binary PV-DBOW codes are more efficient for indexing than long 128-bit semantic hashing codes.\nWe also compared binary paragraph vectors against codes constructed by first inferring short, real-valued paragraph vectors and then using a separate hashing algorithm for binarization. When the dimensionality of the paragraph vectors is equal to the size of binary codes, the number of network parameters in this approach is similar to that of Binary PV models. We experimented with two standard hashing algorithms, namely random hyperplane projection BIBREF19 and iterative quantization BIBREF20 . Paragraph vectors in these experiments were inferred using PV-DBOW with bigrams. Results reported in Table TABREF9 show no benefit from using a separate algorithm for binarization. On the 20 Newsgroups and RCV1 datasets Binary PV-DBOW yielded higher MAP than the two baseline approaches. On English Wikipedia iterative quantization achieved MAP equal to Binary PV-DBOW, while random hyperplane projection yielded lower MAP. Some gain in precision of top hits can be observed for iterative quantization, as indicated by NDCG@10. However, precision of top hits can also be improved by querying with Real-Binary PV-DBOW model (Section SECREF15 ). It is also worth noting that end-to-end inference in Binary PV models is more convenient than inferring real-valued vectors and then using another algorithm for hashing.\n BIBREF15 argue that PV-DBOW outperforms PV-DM on a sentiment classification task, and demonstrate that the performance of PV-DBOW can be improved by including bigrams in the vocabulary. We observed similar results with Binary PV models. That is, including bigrams in the vocabulary usually improved retrieval precision. Also, codes learned with Binary PV-DBOW provided higher retrieval precision than Binary PV-DM codes. Furthermore, to choose the context size for the Binary PV-DM models, we evaluated several networks on validation sets taken out of the training data. The best results were obtained with a minimal one-word, one-sided context window. This is the distributed memory architecture most similar to the Binary PV-DBOW model.\nTo assess the performance of binary paragraph vectors, we carried out experiments on three datasets: 20 Newsgroups1 , a cleansed version (also called v2) of Reuters Corpus Volume 12 (RCV1) and English Wikipedia3 .",

        "question": "What is \"never look back \" behavior?",
        "answer": "It is the behavior they have observed that the model never reffers to tokens that were referred to.",
        "evidence": "Rendering natural language descriptions from structured data is required in a wide variety of commercial applications such as generating descriptions of products, hotels, furniture, etc., from a corresponding table of facts about the entity. Such a table typically contains {field, value} pairs where the field is a property of the entity (e.g., color) and the value is a set of possible assignments to this property (e.g., color = red). Another example of this is the recently introduced task of generating one line biography descriptions from a given Wikipedia infobox BIBREF0 . The Wikipedia infobox serves as a table of facts about a person and the first sentence from the corresponding article serves as a one line description of the person. Figure FIGREF2 illustrates an example input infobox which contains fields such as Born, Residence, Nationality, Fields, Institutions and Alma Mater. Each field further contains some words (e.g., particle physics, many-body theory, etc.). The corresponding description is coherent with the information contained in the infobox.\nNote that the number of fields in the infobox and the ordering of the fields within the infobox varies from person to person. Given the large size (700K examples) and heterogeneous nature of the dataset which contains biographies of people from different backgrounds (sports, politics, arts, etc.), it is hard to come up with simple rule-based templates for generating natural language descriptions from infoboxes, thereby making a case for data-driven models. Based on the recent success of data-driven neural models for various other NLG tasks BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , one simple choice is to treat the infobox as a sequence of {field, value} pairs and use a standard seq2seq model for this task. However, such a model is too generic and does not exploit the specific characteristics of this task as explained below. First, note that while generating such descriptions from structured data, a human keeps track of information at two levels. Specifically, at a macro level, she would first decide which field to mention next and then at a micro level decide which of the values in the field needs to be mentioned next. For example, she first decides that at the current step, the field occupation needs attention and then decides which is the next appropriate occupation to attend to from the set of occupations (actor, director, producer, etc.). To enable this, we use a bifocal attention mechanism which computes an attention over fields at a macro level and over values at a micro level. We then fuse these attention weights such that the attention weight for a field also influences the attention over the values within it. Finally, we feed a fused context vector to the decoder which contains both field level and word level information. Note that such two-level attention mechanisms BIBREF6 , BIBREF7 , BIBREF8 have been used in the context of unstructured data (as opposed to structured data in our case), where at a macro level one needs to pay attention to sentences and at a micro level to words in the sentences.\nNext, we observe that while rendering the output, once the model pays attention to a field (say, occupation) it needs to stay on this field for a few timesteps (till all the occupations are produced in the output). We refer to this as the stay on behavior. Further, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it. We refer to this as the never look back behavior. To model the stay on behaviour, we introduce a forget (or remember) gate which acts as a signal to decide when to forget the current field (or equivalently to decide till when to remember the current field). To model the never look back behaviour we introduce a gated orthogonalization mechanism which ensures that once a field is forgotten, subsequent field context vectors fed to the decoder are orthogonal to (or different from) the previous field context vectors.\nWe experiment with the WikiBio dataset BIBREF0 which contains around 700K {infobox, description} pairs and has a vocabulary of around 400K words. We show that the proposed model gives a relative improvement of 21% and 20% as compared to current state of the art models BIBREF0 , BIBREF9 on this dataset. The proposed model also gives a relative improvement of 10% as compared to the basic seq2seq model. Further, we introduce new datasets for French and German on the same lines as the English WikiBio dataset. Even on these two datasets, our model outperforms the state of the art methods mentioned above.\nFurther, we note that once the tokens of a field are referred to, they are usually not referred to later. For example, once all the occupations have been listed in the output we will never visit the occupation field again because there is nothing left to say about it.

The open-domain TREC question corpus is a set of 5,952 short factoid questions paired with a taxonomy developed by Li and Roth BIBREF6 that includes 6 coarse answer types (such as entities, locations, and numbers), and 50 fine-grained types (e.g. specific kinds of entities, such as animals or vehicles). While a wide variety of syntactic, semantic, and other features and classification methods have been applied to this task, culminating in near-perfect classification performance BIBREF7 , recent work has demonstrated that QC methods developed on TREC questions generally fail to transfer to datasets with more complex questions such as those in the biomedical domain BIBREF3 , likely due in part to the simplicity and syntactic regularity of the questions, and the ability for simpler term-frequency models to achieve near-ceiling performance BIBREF8 . In this work we explore question classification in the context of multiple choice science exams. Standardized science exams have been proposed as a challenge task for question answering BIBREF9 , as most questions contain a variety of challenging inference problems BIBREF10 , BIBREF11 , require detailed scientific and common-sense knowledge to answer and explain the reasoning behind those answers BIBREF12 , and questions are often embedded in complex examples or other distractors.

However, one of the drawbacks of RPA-bots is their susceptibility to changes in defined scenarios: being designed for a particular task, the RPA-bot is usually not adaptable to other domains or even light modifications in a workflow BIBREF0. This inability to readjust to shifting conditions gave rise to Intelligent Process Automation (IPA) systems. IPA-bots combine RPA with Artificial Intelligence (AI) and thus are able to execute more cognitively demanding tasks that require i.a. reasoning and language understanding. Hence, IPA-bots advanced beyond automating shallow “click tasks” and can perform jobs more intelligently – by means of machine learning algorithms. Such IPA-systems undertake time-consuming and routine tasks, and thus enable smart workflows and free up skilled workers to accomplish higher-value activities.\nOne of the potential applications of Natural Language Processing (NLP) within the IPA domain are conversational interfaces that enable human-to-machine interaction. The main benefit of conversational systems is their ability to give attention to several users simultaneously while supporting natural communication. A conventional dialogue system comprises multiple stages and involves different types of NLP subtasks, starting with Natural Language Understanding (NLU) (e.g., intent classification, named entity extraction) and going towards dialogue management (i.e., determining the next possible bot action, considering the dialogue history) and response generation (e.g., converting the semantic representation of the next system action into a natural language utterance). A typical dialogue system for IPA purposes undertakes shallow customer support requests (e.g., answering of FAQs), allowing human workers to focus on more sophisticated inquiries.\nRecent research in the dialogue generation domain is conducted by employing AI-techniques like machine and deep learning BIBREF1, BIBREF2. However, conventional supervised methods have limitations when applied to real-world data and industrial tasks. The primary challenge here refers to a training phase since a robust model requires an extensive amount of structured and labeled data, that is often not available for domain-specific problems. Especially if it concerns dialogue data, which has to be appropriately structured as well as labeled and annotated with additional information. Therefore, despite the popularity of deep learning end-to-end models, one still needs to rely on conventional pipelines in practical dialogue engineering, especially while setting a new domain. However, with few structured data available, transfer learning methods can be used. Such algorithms enable training of the systems with less or even a minimal amount of data, and are able to transfer the knowledge obtained during the training on existing data to the unseen domain.\nThis paper addresses the challenge of implementing a dialogue system for IPA purposes within the practical e-learning domain with the initial absence of training data.",

This handles ambiguous tweets by permitting systems to return any of the annotated languages. Table TABREF10 shows that using the content model alone is more effective for languages that are distinct in our set of languages (i.e. English and Basque). For similar languages, adding the social model helps discriminate them (i.e. Spanish, Portuguese, Catalan and Galician), particularly those where a less-resourced language is similar to a more popular one.

Those between the ages of 16 and 55, will need to apply for an e-visa at the following website: https://e-visa.gov.uz/main. Applicants will need a US passport valid for at least 90 days from the date of the e-visa issuance. Applicants will also need to upload a passport photo (35x40mm size, 300 dip resolution, and less than 1MB file size), a photo (also less than 1MB file size) of page 2 of the passport, and $20 USD plus service fee chargeable to a VISA credit card.\n\nPlease note that although the e-visa application will ask the applicant to enter dates they will be in Uzbekistan, the e-visa will be valid beginning 30 days after the application date. Therefore, it is recommended that applicants apply between 30-60 days before they plan to enter Uzbekistan. If the applicant plans to visit Uzbekistan starting June 1, they should apply for the e-visa no later than May 1.\n\nUzbekistan e-visa windows are 90 days, but are only valid 30 days once the applicant enters Uzbekistan. For example, if the applicant applies for an e-visa on May 1, they will receive an e-visa window permitting them to single-entry into country anytime between June 1 – August 31. If the applicant enters Uzbekistan on June 1, the visa will be valid until June 30.\n\nIt is recommended that an applicant not apply more than 90 days than the date the applicant plans to exit Uzbekistan. For example, if the applicant intends to visit Uzbekistan between June 1 – June 15, the earliest the applicant can apply is March 15. The e-visa issued would be valid between April 15 – June 15. \n\nOnce the application is submitted, the applicant will receive an email to submit payment for the visa. Uzbekistan e-visas are nonrefundable. If there is a mistake in the details or dates, the e-visa should be considered invalid and the applicant must begin a new application and pay the fee again.\n\nPlease allow at least 3 business days for processing after payment. Afterward, the applicant will receive a link to download the pdf of their e-visa to Uzbekistan.

At the heart of the Transformer lie multi-head attention mechanisms: each word is represented by multiple different weighted averages of its relevant context. As suggested by recent works on interpreting attention head roles, separate attention heads may learn to look for various relationships between tokens BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9.\nThe attention distribution of each head is predicted typically using the softmax normalizing transform. As a result, all context words have non-zero attention weight. Recent work on single attention architectures suggest that using sparse normalizing transforms in attention mechanisms such as sparsemax – which can yield exactly zero probabilities for irrelevant words – may improve performance and interpretability BIBREF12, BIBREF13, BIBREF14. Qualitative analysis of attention heads BIBREF0 suggests that, depending on what phenomena they capture, heads tend to favor flatter or more peaked distributions.\nRecent works have proposed sparse Transformers BIBREF10 and adaptive span Transformers BIBREF11. However, the “sparsity\" of those models only limits the attention to a contiguous span of past tokens, while in this work we propose a highly adaptive Transformer model that is capable of attending to a sparse set of words that are not necessarily contiguous. Figure FIGREF1 shows the relationship of these methods with ours.\nOur contributions are the following:\nWe introduce sparse attention into the Transformer architecture, showing that it eases interpretability and leads to slight accuracy gains.\nWe propose an adaptive version of sparse attention, where the shape of each attention head is learnable and can vary continuously and dynamically between the dense limit case of softmax and the sparse, piecewise-linear sparsemax case.\nWe make an extensive analysis of the added interpretability of these models, identifying both crisper examples of attention head behavior observed in previous work, as well as novel behaviors unraveled thanks to the sparsity and adaptivity of our proposed model.\nRecent works have proposed sparseTransformers (Child et al., 2019) and adaptive span Transformers (Sukhbaatar et al., 2019).

These two datasets are created to avoid reversible relation problems, thus the prediction task becomes more realistic and hence more challenging BIBREF18 . Table TABREF7 presents the statistics of WN18RR and FB15k-237.\nEvaluation protocol: Following BIBREF3 , for each valid test triple INLINEFORM0 , we replace either INLINEFORM1 or INLINEFORM2 by each of all other entities to create a set of corrupted triples. We use the “Filtered” setting protocol BIBREF3 , i.e., not taking any corrupted triples that appear in the KG into accounts. We rank the valid test triple and corrupted triples in descending order of their scores. We employ evaluation metrics: mean rank (MR), mean reciprocal rank (MRR) and Hits@10 (i.e., the proportion of the valid test triples ranking in top 10 predictions). Lower MR, higher MRR or higher Hits@10 indicate better performance. Final scores on the test set are reported for the model obtaining the highest Hits@10 on the validation set.\nTraining protocol: We use the common Bernoulli strategy BIBREF20 , BIBREF21 when sampling invalid triples. For WN18RR, BIBREF22 found a strong evidence to support the necessity of a WordNet-related semantic setup, in which they averaged pre-trained word embeddings for word surface forms within the WordNet to create synset embeddings, and then used these synset embeddings to initialize entity embeddings for training their TransE association model. We follow this evidence in using the pre-trained 100-dimensional Glove word embeddings BIBREF23 to train a TransE model on WN18RR.\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 . For ConvKB, we use a new process of training up to 100 epochs and monitor the Hits@10 score after every 10 training epochs to choose optimal hyper-parameters with the Adam initial learning rate in INLINEFORM0 and the number of filters INLINEFORM1 in INLINEFORM2 . We obtain the highest Hits@10 scores on the validation set when using N= 400 and the initial learning rate INLINEFORM3 on WN18RR; and N= 100 and the initial learning rate INLINEFORM4 on FB15k-237.\nLike in ConvKB, we use the same pre-trained entity and relation embeddings produced by TransE to initialize entity and relation embeddings in our CapsE for both WN18RR and FB15k-237 ( INLINEFORM0 ). We set the batch size to 128, the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM1 ), and the number of iterations in the routing algorithm INLINEFORM2 in INLINEFORM3 . We run CapsE up to 50 epochs and monitor the Hits@10 score after each 10 training epochs to choose optimal hyper-parameters. The highest Hits@10 scores for our CapsE on the validation set are obtained when using INLINEFORM4 , INLINEFORM5 and the initial learning rate at INLINEFORM6 on WN18RR; and INLINEFORM7 , INLINEFORM8 and the initial learning rate at INLINEFORM9 on FB15k-237.\nDataset: We use the SEARCH17 dataset BIBREF12 of query logs of 106 users collected by a large-scale web search engine. A log entity consists of a user identifier, a query, top-10 ranked documents returned by the search engine and clicked documents along with the user's dwell time. BIBREF12 constructed short-term (session-based) user profiles and used the profiles to personalize the returned results. They then employed the SAT criteria BIBREF26 to identify whether a returned document is relevant from the query logs as either a clicked document with a dwell time of at least 30 seconds or the last clicked document in a search session (i.e., a SAT click). After that, they assigned a INLINEFORM0 label to a returned document if it is a SAT click and also assigned INLINEFORM1 labels to the remaining top-10 documents. The rank position of the INLINEFORM2 labeled documents is used as the ground truth to evaluate the search performance before and after re-ranking.\nThe dataset was uniformly split into the training, validation and test sets. This split is for the purpose of using historical data in the training set to predict new data in the test set BIBREF12 . The training, validation and test sets consist of 5,658, 1,184 and 1,210 relevant (i.e., valid) triples; and 40,239, 7,882 and 8,540 irrelevant (i.e., invalid) triples, respectively.\nEvaluation protocol: Our CapsE is used to re-rank the original list of documents returned by a search engine as follows: (i) We train our model and employ the trained model to calculate the score for each INLINEFORM0 triple. (ii) We then sort the scores in the descending order to obtain a new ranked list. To evaluate the performance of our proposed model, we use two standard evaluation metrics: mean reciprocal rank (MRR) and Hits@1. For each metric, the higher value indicates better ranking performance.\nWe compare CapsE with the following baselines using the same experimental setup: (1) SE: The original rank is returned by the search engine. (2) CI BIBREF27 : This baseline uses a personalized navigation method based on previously clicking returned documents. (3) SP BIBREF9 , BIBREF11 : A search personalization method makes use of the session-based user profiles. (4) Following BIBREF12 , we use TransE as a strong baseline model for the search personalization task. Previous work shows that the well-known embedding model TransE, despite its simplicity, obtains very competitive results for the knowledge graph completion BIBREF28 , BIBREF29 , BIBREF14 , BIBREF30 , BIBREF15 . (5) The CNN-based model ConvKB is the most closely related model to our CapsE.\nEmbedding initialization: We follow BIBREF12 to initialize user profile, query and document embeddings for the baselines TransE and ConvKB, and our CapsE.\nWe train a LDA topic model BIBREF31 with 200 topics only on the relevant documents (i.e., SAT clicks) extracted from the query logs. We then use the trained LDA model to infer the probability distribution over topics for every returned document. We use the topic proportion vector of each document as its document embedding (i.e. INLINEFORM0 ). In particular, the INLINEFORM1 element ( INLINEFORM2 ) of the vector embedding for document INLINEFORM3 is: INLINEFORM4 where INLINEFORM5 is the probability of the topic INLINEFORM6 given the document INLINEFORM7 .\nWe also represent each query by a probability distribution vector over topics. Let INLINEFORM0 be the set of top INLINEFORM1 ranked documents returned for a query INLINEFORM2 (here, INLINEFORM3 ). The INLINEFORM4 element of the vector embedding for query INLINEFORM5 is defined as in BIBREF12 : INLINEFORM6 , where INLINEFORM7 is the exponential decay function of INLINEFORM8 which is the rank of INLINEFORM9 in INLINEFORM10 . And INLINEFORM11 is the decay hyper-parameter ( INLINEFORM12 ). Following BIBREF12 , we use INLINEFORM13 . Note that if we learn query and document embeddings during training, the models will overfit to the data and will not work for new queries and documents. Thus, after the initialization process, we fix (i.e., not updating) query and document embeddings during training for TransE, ConvKB and CapsE.\nIn addition, as mentioned by BIBREF9 , the more recently clicked document expresses more about the user current search interest. Hence, we make use of the user clicked documents in the training set with the temporal weighting scheme proposed by BIBREF11 to initialize user profile embeddings for the three embedding models.\nHyper-parameter tuning: For our CapsE model, we set batch size to 128, and also the number of neurons within the capsule in the second capsule layer to 10 ( INLINEFORM0 ). The number of iterations in the routing algorithm is set to 1 ( INLINEFORM1 ). For the training model, we use the Adam optimizer with the initial learning rate INLINEFORM2 INLINEFORM3 INLINEFORM4 INLINEFORM5 INLINEFORM6 INLINEFORM7 . We also use ReLU as the activation function INLINEFORM8 . We select the number of filters INLINEFORM9 . We run the model up to 200 epochs and perform a grid search to choose optimal hyper-parameters on the validation set. We monitor the MRR score after each training epoch and obtain the highest MRR score on the validation set when using INLINEFORM10 and the initial learning rate at INLINEFORM11 .\nWe employ the TransE and ConvKB implementations provided by BIBREF24 and BIBREF15 and then follow their training protocols to tune hyper-parameters for TransE and ConvKB, respectively. We also monitor the MRR score after each training epoch and attain the highest MRR score on the validation set when using margin = 5, INLINEFORM0 -norm and SGD learning rate at INLINEFORM1 for TransE; and INLINEFORM2 and the Adam initial learning rate at INLINEFORM3 for ConvKB.\nA log entity consists of a user identifier, a query, top10 ranked documents returned by the search engine and clicked documents along with the user’s dwell time.",

        "answer": "A new deep neural network architecture that jointly leverage pre-trained word embedding and character embedding to represent the meaning sentences.",
        "evidence": "Traditional approaches BIBREF0 , BIBREF1 , BIBREF2 for sentence relation modeling tasks such as paraphrase identification, question answering, recognized textual entailment and semantic textual similarity prediction usually build the supervised model using a variety of hand crafted features. Hundreds of features generated at different linguistic levels are exploited to boost classification. With the success of deep learning, there has been much interest in applying deep neural network based techniques to further improve the prediction performances BIBREF3 , BIBREF4 , BIBREF5 .\nA key component of deep neural network is word embedding which serve as an lookup table to get word representations. From low level NLP tasks such as language modeling, POS tagging, name entity recognition, and semantic role labeling BIBREF6 , BIBREF7 , to high level tasks such as machine translation, information retrieval and semantic analysis BIBREF8 , BIBREF9 , BIBREF10 . Deep word representation learning has demonstrated its importance for these tasks. All the tasks get performance improvement via further learning either word level representations or sentence level representations. On the other hand, some researchers have found character-level convolutional networks BIBREF11 , BIBREF12 are useful in extracting information from raw signals for the task such as language modeling or text classification.\nIn this work, we focus on deep neural network based sentence relation modeling tasks. We explore treating each sentence as a kind of raw signal at character level, and applying temporal (one-dimensional) Convolution Neural Network (CNN) BIBREF6 , Highway Multilayer Perceptron (HMLP) and multi-layer bidirectional LSTM (Long Short Term Memory) BIBREF13 to learn sentence representations. We propose a new deep neural network architecture that jointly leverage pre-trained word embedding and character embedding to represent the meaning sentences. More specifically, our new approach first generates two kinds of word sequence representations. One kind of sequence representations are the composition of pre-trained word vectors. The other kind of sequence representation comprise word vectors that generating from character-level convolutional network. We then inject the two sequence representations into bidirectional LSTM, which means forward directional LSTM accept pre-trained word embedding output and backward directional LSTM accept auxiliary character CNN embedding output. The final sentence representation is the concatenation of the two direction. After that, we construct matching features followed by another temporal CNN to learn high-level hidden matching feature representations. Figure FIGREF1 shows the neural network architecture for general sentence relation modeling.\nOur model shows that when trained on small size datasets, combining pre-trained word embeddings with auxiliary character-level embedding can improve the sentence representation. Word embeddings can help capturing general word semantic meanings, whereas char-level embedding can help modeling task specific word meanings. Note that auxiliary character-level embedding based sentence representation do not require the knowledge of words or even syntactic structure of a language. The enhanced sentence representation generated by multi-layer bidirectional LSTM will encapsulate the character and word levels informations. Furthermore, it may enhance matching features that generated by computing similarity measures on sentence pairs. Quantitative evaluations on standard dataset demonstrate the effectiveness and advantages of our method.\nWe propose a new deep neural network architecture that jointly leverage pre-trained word embedding and character embedding to represent the meaning sentences.

        "evidence": "Recently, with the emergence of neural seq2seq models, abstractive summarization methods have seen great performance strides BIBREF0, BIBREF1, BIBREF2. However, complex neural summarization models with thousands of parameters usually require a large amount of training data. In fact, much of the neural summarization work has been trained and tested in news domains where numerous large datasets exist. For example, the CNN/DailyMail (CNN/DM) BIBREF3, BIBREF4 and New York Times (NYT) datasets are in the magnitude of 300k and 700k documents, respectively. In contrast, in other domains such as student reflections, summarization datasets are only in the magnitude of tens or hundreds of documents (e.g., BIBREF5). We hypothesize that training complex neural abstractive summarization models in such domains will not yield good performing models, and we will indeed later show that this is the case for student reflections.\nTo improve performance in low resource domains, we explore three directions. First, we explore domain transfer for abstractive summarization. While domain transfer is not new, compared to prior summarization studies BIBREF6, BIBREF7, our training (news) and tuning (student reflection) domains are quite dissimilar, and the in-domain data is small. Second, we propose a template-based synthesis method to create synthesized summaries, then explore the effect of enriching training data for abstractive summarization using the proposed model compared to a synthesis baseline. Lastly, we combine both directions. Evaluations of neural abstractive summarization method across four student reflection corpora show the utility of all three methods.\nSecond, we propose a template-based synthesis method to create synthesized summaries, then explore the effect of enriching training data for abstractive summarization using the proposed model compared to a synthesis baseline.",

        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nIn order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv, by applying a greedy oracle labeling algorithm.",

        "answer": "Brazilian Jiujitsu, or BJJ, is known as the gentle art in martial arts.  BJJ can be practiced in two modalities: Sport BJJ and the other as self defense. Sport BJJ is competitive and based on a point system based on a competitor being awarded a number of points based on advancing to a more advantageous position. Alternatively, a competitor may immediately win the match by submission. When BJJ is used in self defense, the goal is usually to subdue an attacker.  Since BJJ is mostly grappling from the ground, it can be a highly effective practice for self defense as many street fights end up on the ground. While many of the techniques are intended to immobilize an opponent, it can be less effective if the opponent has an unfair advantage such as the use of a weapon. Practicing BJJ routinely will prepare the practitioner mentally for physical combat which can be advantageous in a self defense scenario. Another reason BJJ can be viewed as good for self defense is that there are techniques that can work well for different body types that level the playing field for even smaller or weaker opponents. If both opponents are trained in BJJ, size and strength can become a larger factor.  Routine training can also lead to increased physical fitness as classes can be quite rigorous and physically demanding.

        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nIn contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work.",

        "answer": "No.",
        "evidence": "The prevalent use of emoji—and their text-based precursors—is mostly unaddressed in current natural language processing (NLP) tasks. The support of the Unicode Standard BIBREF0 for emoji characters in 2010 ushered in a wide-spread, international adoption of these graphical elements in casual contexts. Interpreting the meaning of these characters has been challenging however, since they take on multiple semantic roles BIBREF1.\nWhether or not emoji are used depends on the context of a text or conversation, with more formal settings generally being less tolerating. So is the popular aligned corpus Europarl BIBREF2 naturally devoid of emoji. Technical limitations, like no Unicode support, also limit its use. This in turn affects commonly used corpora, tokenizers, and pre-trained networks.\nTake for example the Ubuntu Dialog Corpus by BIBREF3, a commonly used corpus for multi-turn systems. This dataset was collected from an Internet Relay Chat (IRC) room casually discussing the operating system Ubuntu. IRC nodes usually support the ASCII text encoding, so there's no support for graphical emoji. However, in the 7,189,051 utterances, there are only 9946 happy emoticons (i.e. :-) and the cruelly denosed :) version) and 2125 sad emoticons.\nWord embeddings are also handling emoji poorly: Word2vec BIBREF4 with the commonly used pre-trained Google News vectors doesn't support the graphical emoji at all and vectors for textual emoticons are inconsistent. As another example with contextualized word embeddings, there are also no emoji or textual emoticons in the vocabulary list of BERT BIBREF5 by default and support for emoji is only recently added to the tokenizer. The same is true for GPT-2 BIBREF6. As all downstream systems, ranging from multilingual résumé parsing to fallacy detection BIBREF7, rely on the completeness of these embeddings, this lack of emoji support can affect the performance of some of these systems.\nAnother challenge is that emoji usage isn't static. Think of shifting conventions, different cultures, and newly added emoji to the Unicode list. Several applications also use their own custom emoji, like chat application Slack and streaming service Twitch. This becomes an issue for methods that leverage the Unicode description BIBREF8 or that rely on manual annotations BIBREF9.\nOur contribution with this paper is two-fold: firstly, we argue that the current use—or rather non-existing use—of emoji in the tokenizing, training, and the datasets themselves is insufficient. Secondly, we attempt to quantify the significance of incorporating emoji-based features by presenting a fine-tuned model. We then compare this model to a baseline, but without special attention to emoji.\nSection SECREF2 will start with an overview of work on emoji representations, emoji-based models and analysis of emoji usage. A brief introduction in conversational systems will also be given. Section SECREF3 will then look into popular datasets with and without emoji and then introduce the dataset we used.\nOur model will then be discussed in Section SECREF4, including the tokenization in Subsection SECREF4, training setup in Subsection SECREF6 and evaluation in Subsection SECREF10. This brings us to the results of our experiment, which is discussed in Section SECREF5 and finally our conclusion and future work are presented in Section SECREF6.\nSecondly, we attempt to quantify the significance of incorporating emoji-based features by presenting a fine-tuned model.

While there are various hypotheses as to reason for these effects, the most likely explanation is some level of optical illusion as the road is tilted at a severe opposite angle to the tilted roof line and the inside of the cabin. I think a combination of gravity hill where you get the sensation you are climbing up the road when in reality you are going down and the odd tilted angles of the cabin causes severe optical illusion.

However, there is debate as to whether he believed in multiple worlds, and if he did, whether those worlds were co-existent or successive. The first to whom we can definitively attribute the concept of innumerable worlds are the Ancient Greek Atomists, beginning with Leucippus and Democritus in the 5th century BCE, followed by Epicurus (341-270 BCE) and Lucretius (1st century BCE). In the third century BCE, the philosopher Chrysippus suggested that the world eternally expired and regenerated, effectively suggesting the existence of multiple universes across time. The concept of multiple universes became more defined in the Middle Ages. The American philosopher and psychologist William James used the term \"multiverse\" in 1895, but in a different context. The concept first appeared in the modern scientific context in the course of the debate between Boltzmann and Zermelo in 1895. In Dublin in 1952, Erwin Schrödinger gave a lecture in which he jocularly warned his audience that what he was about to say might \"seem lunatic\".

The input papers ranged from 6 to 8 pages and were converted from PDF format to plain text using an off-the-shelf tool. The only preprocessing applied is a systematic dehyphenation at line breaks and removal of author-assigned keyphrases. Scientific articles were selected from four different research areas as defined in the ACM classification, and were equally distributed into training (144 articles) and test (100 articles) sets. Gold standard keyphrases are composed of both author-assigned keyphrases collected from the original PDF files and reader-assigned keyphrases provided by student annotators.\nLong documents such as those in the SemEval-2010 benchmark dataset are notoriously difficult to handle due to the large number of keyphrase candidates (i.e. phrases that are eligible to be keyphrases) that the systems have to cope with BIBREF6 . Furthermore, noisy textual content, whether due to format conversion errors or to unusable elements (e.g. equations), yield many spurious keyphrase candidates that negatively affect keyphrase extraction performance. This is particularly true for systems that make use of core NLP tools to select candidates, that in turn exhibit poor performance on degraded text. Filtering out irrelevant text is therefore needed for addressing these issues.\nIn this study, we concentrate our effort on re-assessing keyphrase extraction performance on three increasingly sophisticated levels of document preprocessing described below.\nTable shows the average number of sentences and words along with the maximum possible recall for each level of preprocessing. The maximum recall is obtained by computing the fraction of the reference keyphrases that occur in the documents. We observe that the level 2 preprocessing succeeds in eliminating irrelevant text by significantly reducing the number of words (-19%) while maintaining a high maximum recall (-2%). Level 3 preprocessing drastically reduce the number of words to less than a quarter of the original amount while interestingly still preserving high recall.\nLevel 2: Similarly to (Nguyen and Luong, 2010; Lopez and Romary, 2010), we retrieve6 the original PDF files from the ACM Digital Library.

        "evidence": "Diagrams are a common feature of many everyday media from newspapers to school textbooks, and not surprisingly, different forms of diagrammatic representation have been studied from various perspectives. To name just a few examples, recent work has examined patterns in diagram design BIBREF0 and their interpretation in context BIBREF1, and developed frameworks for classifying diagrams BIBREF2 and proposed guidelines for their design BIBREF3. There is also a long-standing interest in processing and generating diagrams computationally BIBREF4, BIBREF5, BIBREF6, which is now resurfacing as advances emerging from deep learning for computer vision and natural language processing are brought to bear on diagrammatic representations BIBREF7, BIBREF8, BIBREF9.\nFrom the perspective of computational processing, diagrammatic representations present a formidable challenge, as they involve tasks from both computer vision and natural language processing. On the one hand, diagrams have a spatial organisation – layout – which needs to be segmented to identify meaningful units and their position. Making sense of how diagrams exploit the 2D layout space falls arguably within the domain of computer vision. On the other hand, diagrams also have a discourse structure, which uses the layout space to set up discourse relations between instances of natural language, various types of images, arrows and lines, thus forming a unified discourse organisation. The need to parse this discourse structure shifts the focus towards the field of natural language processing.\nUnderstanding and making inferences about the structure of diagrams and other forms of multimodal discourse may be broadly conceptualised as multimodal discourse parsing. Recent examples of work in this area include alikhanietal2019 and ottoetal2019, who model discourse relations between natural language and photographic images, drawing on linguistic theories of coherence and text–image relations, respectively. In most cases, however, predicting a single discourse relation covers only a part of the discourse structure. sachanetal2019 note that there is a need for comprehensive theories and models of multimodal communication, as they can be used to rethink tasks that have been previously considered only from the perspective of natural language processing.\nUnlike many other areas, the study of diagrammatic representations is particularly well-resourced, as several multimodal resources have been published recently to support research on computational processing of diagrams BIBREF10, BIBREF8, BIBREF11. This study compares two such resources, AI2D BIBREF10 and AI2D-RST BIBREF11, which both feature the same diagrams, as the latter is an extension of the former. Whereas AI2D features crowd-sourced, non-expert annotations, AI2D-RST provides multiple layers of expert annotations, which are informed by state-of-the-art approaches to multimodal communication BIBREF12 and annotation BIBREF13, BIBREF14.\nThis provides an interesting setting for comparison and evaluation, as non-expert annotations are cheap to produce and easily outnumber the expert-annotated data, whose production consumes both time and resources. Expert annotations, however, incorporate domain knowledge from multimodality theory, which is unavailable via crowd-sourcing. Whether expert annotations provide better representations of diagrammatic structures and thus justify their higher cost is one question that this study seeks to answer.\nBoth AI2D and AI2D-RST represent the multimodal structure of diagrams using graphs. This enables learning their representations using graph neural networks, which are gaining currency as a graph is a natural choice for representing many types of data BIBREF15. This article reports on two experiments that evaluate the capability of AI2D and AI2D-RST to represent the multimodal structure of diagrams using graphs, focusing particularly on spatial layout, the hierarchical organisation of diagram elements and their connections expressed using arrows and lines.\nThis article reports on two experiments that evaluate the capability of AI2D and AI2D-RST to represent the multimodal structure of diagrams using graphs, focusing particularly on spatial layout, the hierarchical organisation of diagram elements and their connections expressed using arrows and lines.",

        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nIn this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations (Kim, 2014), and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.",

        "evidence": "Performance appraisal (PA) is an important HR process, particularly for modern organizations that crucially depend on the skills and expertise of their workforce. The PA process enables an organization to periodically measure and evaluate every employee's performance. It also provides a mechanism to link the goals established by the organization to its each employee's day-to-day activities and performance. Design and analysis of PA processes is a lively area of research within the HR community BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 .\nThe PA process in any modern organization is nowadays implemented and tracked through an IT system (the PA system) that records the interactions that happen in various steps. Availability of this data in a computer-readable database opens up opportunities to analyze it using automated statistical, data-mining and text-mining techniques, to generate novel and actionable insights / patterns and to help in improving the quality and effectiveness of the PA process BIBREF4 , BIBREF5 , BIBREF6 . Automated analysis of large-scale PA data is now facilitated by technological and algorithmic advances, and is becoming essential for large organizations containing thousands of geographically distributed employees handling a wide variety of roles and tasks.\nA typical PA process involves purposeful multi-step multi-modal communication between employees, their supervisors and their peers. In most PA processes, the communication includes the following steps: (i) in self-appraisal, an employee records his/her achievements, activities, tasks handled etc.; (ii) in supervisor assessment, the supervisor provides the criticism, evaluation and suggestions for improvement of performance etc.; and (iii) in peer feedback (aka INLINEFORM0 view), the peers of the employee provide their feedback. There are several business questions that managers are interested in. Examples:\nIn this paper, we develop text mining techniques that can automatically produce answers to these questions. Since the intended users are HR executives, ideally, the techniques should work with minimum training data and experimentation with parameter setting. These techniques have been implemented and are being used in a PA system in a large multi-national IT company.\nThe rest of the paper is organized as follows. Section SECREF2 summarizes related work. Section SECREF3 summarizes the PA dataset used in this paper. Section SECREF4 applies sentence classification algorithms to automatically discover three important classes of sentences in the PA corpus viz., sentences that discuss strengths, weaknesses of employees and contain suggestions for improving her performance. Section SECREF5 considers the problem of mapping the actual targets mentioned in strengths, weaknesses and suggestions to a fixed set of attributes. In Section SECREF6 , we discuss how the feedback from peers for a particular employee can be summarized.

        "answer": "BERT language model.",
        "evidence": "UTF8gkai With the widespread of electronic health records (EHRs) in recent years, a large number of EHRs can be integrated and shared in different medical environments, which further support the clinical decision making and government health policy formulationBIBREF0. However, most of the information in current medical records is stored in natural language texts, which makes data mining algorithms unable to process these data directly. To extract relational entity triples from the text, researchers generally use entity and relation extraction algorithm, and rely on the central word to convert the triples into key-value pairs, which can be processed by conventional data mining algorithms directly. Fig. FIGREF1 shows an example of entity and relation extraction in the text of EHRs. The text contains three relational entity triples, i.e., $<$咳嗽, 程度等级, 反复$>$ ($<$cough, degree, repeated$>$), $<$咳痰, 程度等, 反复$>$ ($<$expectoration, degree, repeated$>$) and $<$发热, 存在情况, 无$>$ ($<$fever, presence, nonexistent$>$). By using the symptom as the central word, these triples can then be converted into three key-value pairs, i.e., $<$咳嗽的程度等级, 反复$>$ ($<$degree of cough, repeated$>$), $<$咳痰的程度等级, 反复$>$ ($<$degree of expectoration, repeated$>$) and $<$发热的存在情况, 无$>$ ($<$presence of fever, nonexistent$>$).\nUTF8gkai To solve the task of entity and relation extraction, researchers usually follows pipeline processing and split the task into two sub-tasks, namely named entity recognition (NER)BIBREF1 and relation classification (RC)BIBREF2, respectively.\nHowever, this pipeline method usually fails to capture joint features between entity and relationship types. For example, for a valid relation “存在情况(presence)” in Fig. FIGREF1, the types of its two relational entities must be “疾病(disease)”, “症状(symptom)” or “存在词(presence word)”. To capture these joint features, a large number of joint learning models have been proposed BIBREF3, BIBREF4, among which bidirectional long short term memory (Bi-LSTM) BIBREF5, BIBREF6 are commonly used as the shared parameter layer. However, compared with the language models that benefit from abundant knowledge from pre-training and strong feature extraction capability, Bi-LSTM model has relatively lower generalization performance.\nTo improve the performance, a simple solution is to incorporate language model into joint learning as a shared parameter layer. However, the existing models only introduce language models into the NER or RC task separately BIBREF7, BIBREF8. Therefore, the joint features between entity and relationship types still can not be captured. Meanwhile, BIBREF9 considered the joint features, but it also uses Bi-LSTM as the shared parameter layer, resulting the same problem as discussed previously.\nGiven the aforementioned challenges and current researches, we propose a focused attention model based on widely known BERT language model BIBREF10 to jointly for NER and RC tasks. Specifically, through the dynamic range attention mechanism, we construct task-specific MASK matrix to control the attention range of the last $K$ layers in BERT language model, leading to the model focusing on the words of the task. This process helps obtain the corresponding task-specific context-dependent representations. In this way, the modified BERT language model can be used as the shared parameter layer in joint learning NER and RC task. We call the modified BERT language model shared task representation encoder (STR-encoder) in the following paper.\nTo sum up, the main contributions of our work are summarized as follows:\nWe propose a focused attention model to jointly learn NER and RC task. The model integrates BERT language model as a shared parameter layer to achieve better generalization performance.\nIn the proposed model, we incorporate a novel structure, called STR-encoder, which changes the attention range of the last $K$ layers in BERT language model to obtain task-specific context-dependent representations. It can make full use of the original structure of BERT to produce the vector of the task, and can directly use the prior knowledge contained in the pre-trained language model.\nFor RC task, we proposed two different MASK matrices to extract the required feature representation of RC task. The performances of these two matrices are analyzed and compared in the experiment.\nThe rest of the paper is organized as follows. We briefly review the related work on NER, RC and joint entity and relation extraction in Section SECREF2. In Section SECREF3, we present the proposed focused attention model. We report the experimental results in Section SECREF4. Section SECREF5 is dedicated to studying several key factors that affect the performance of our model. Finally, conclusion and future work are given in Section SECREF6.\nGiven the aforementioned challenges and current researches, we propose a focused attention model based on widely known BERT language model to jointly for NER and RC tasks. Specifically, through the dynamic range attention mechanism, we construct task-specific MASK matrix to control the attention range of the last $K$ layers in BERT language model, leading to the model focusing on the words of the task.",

Its goal is to present statistical analyses of issues of clinical focus based on retrieving and analyzing numerous papers in the medical literature BIBREF0 . The PubMed database is one of the most commonly used databases in EBM BIBREF1 .\nBiomedical papers, describing randomized controlled trials in medical intervention, are published at a high rate every year. The volume of these publications makes it very challenging for physicians to find the best medical intervention for a given patient group and condition BIBREF2 . Computational methods and natural language processing (NLP) could be adopted in order to expedite the process of biomedical evidence synthesis. Specifically, NLP tasks applied to well structured documents and queries can help physicians extract appropriate information to identify the best available evidence in the context of medical treatment.\nClinical questions are formed using the PIO framework, where clinical issues are broken down into four components: Population/Problem (P), Intervention (I), Comparator (C), and Outcome (O). We will refer to these categories as PIO elements, by using the common practice of merging the C and I categories. In BIBREF3 a literature screening performed in 10 systematic reviews was studied. It was found that using the PIO framework can significantly improve literature screening efficacy. Therefore, efficient extraction of PIO elements is a key feature of many EBM applications and could be thought of as a multi-label sentence classification problem.\nPrevious works on PIO element extraction focused on classical NLP methods, such as Naive Bayes (NB), Support Vector Machines (SVM) and Conditional Random Fields (CRF) BIBREF4 , BIBREF5 . These models are shallow and limited in terms of modeling capacity. Furthermore, most of these classifiers are trained to extract PIO elements one by one which is sub-optimal since this approach does not allow the use of shared structure among the individual classifiers.\nDeep neural network models have increased in popularity in the field of NLP. They have pushed the state of the art of text representation and information retrieval. More specifically, these techniques enhanced NLP algorithms through the use of contextualized text embeddings at word, sentence, and paragraph levels BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 .\nMore recently, jin2018pico proposed a bidirectional long short term memory (LSTM) model to simultaneously extract PIO components from PubMed abstracts. To our knowledge, that study was the first in which a deep learning framework was used to extract PIO elements from PubMed abstracts.\nIn the present paper, we build a dataset of PIO elements by improving the methodology found in BIBREF12 . Furthermore, we built a multi-label PIO classifier, along with a boosting framework, based on the state of the art text embedding, BERT.

The abstracts of these articles are then extracted to create answer candidates. The assumption is made that if many queries lead to the same article, it must contain the answer context; however, this assumption fails for some occasions, which makes this dataset more challenging. Since the existence of answer contexts is not guaranteed in this task, it is called answer triggering instead of answer selection.\nSelQA BIBREF7 is a product of five annotation tasks through crowdsourcing. It consists of about 8K questions where a half of the questions are paraphrased from the other half, aiming to reduce contextual similarities between questions and answers. Each question is associated with a section in Wikipedia where the answer context is guaranteed, and also with five sections selected from the entire Wikipedia where the selection is made by the Lucene search engine. This second dataset does not assume the existence of the answer context, so can be used for the evaluation of answer triggering.\nSQuAD BIBREF12 presents 107K+ crowdsourced questions on 536 Wikipedia articles, where the answer contexts are guaranteed to exist within the provided paragraph. It contains annotation of answer phrases as well as the pointers to the sentences including the answer phrases; thus, it can be used for both answer extraction and selection. This corpus also provides human accuracy on those questions, setting up a reasonable upper bound for machines. To avoid overfitting, the evaluation set is not publicly available although system outputs can be evaluated by their provided script.\nInfoboxQA BIBREF13 gives 15K+ questions based on the infoboxes from 150 articles in Wikipedia. Each question is crowdsourced and associated with an infobox, where each line of the infobox is considered an answer candidate. This corpus emphasizes the gravity of infoboxes, which summary arguably the most commonly asked information about those articles.

Going at this fine-grained level can yield more reliable systems and it also makes it possible to explain to the user why an article was judged as propagandist by an automatic system.\nWith this in mind, we organised the shared task on fine-grained propaganda detection at the NLP4IF@EMNLP-IJCNLP 2019 workshop.

        "evidence": "Electroencephalography (EEG) is a non invasive way of measuring electrical activity of human brain. In BIBREF0 we demonstrated deep learning based automatic speech recognition (ASR) using EEG signals for a limited English vocabulary of four words and five vowels. In this paper we extend our work for a much larger English vocabulary and we use state-of-art end-to-end continuous speech recognition models to perform recognition. In our prior work we predicted isolated words and vowels.\nASR systems forms the front end or back end in many cutting edge voice activated technologies like Amazon Alexa, Apple Siri, Windows Cortana, Samsung Bixby etc. Unfortunately these systems are trained to recognize text only from acoustic features. This limits technology accessibility to people with speaking disabilities and disorders. The research work presented in this paper tries to address this issue by investigating speech recognition using only EEG signals with no acoustic input and also by combining EEG features along with traditional acoustic features to perform recognition. We believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.\nASR performance is degraded in presence of noisy speech and in real life situations most of the speech is noisy. Inspired from the unique robustness to environmental artifacts exhibited by the human auditory cortex BIBREF1 , BIBREF2 we used very noisy speech data for this work and demonstrated lower word error rate (WER) for smaller corpus using EEG features, concatenation of EEG features and acoustic features.\nIn BIBREF3 authors decode imagined speech from EEG using synthetic EEG data and connectionist temporal classification (CTC) network but in our work we use real EEG data, use EEG data recorded along with acoustics. In BIBREF4 authors perform envisioned speech recognition using random forest classifier but in our case we use end to end state of art models and perform recognition for noisy speech. In BIBREF5 authors demonstrate speech recognition using electrocorticography (ECoG) signals, which are invasive in nature but in our work we use non invasive EEG signals.\nThis work is mainly motivated by the results explained in BIBREF0 , BIBREF6 , BIBREF7 , BIBREF3 . In BIBREF6 the authors used classification approach for identifying phonological categories in imagined and silent speech but in our work we used continuous speech recognition state of art models and our models were predicting words, characters at each time step. Similarly in BIBREF7 neural network based classification approach was used for predicting phonemes.\nMajor contribution of this paper is the demonstration of end to end continuous noisy speech recognition using only EEG features and this paper further validates the concepts introduced in BIBREF0 for a much larger English corpus.\nWe believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.",

This occurs because the sampling rate of the film is not adequate to capture the frequency of the signal (the frequency that the tires are spinning forwards) and the signal becomes indistinguishable from another signal (a frequency of the tires spinning backwards). As an example of how this happens imagine that the camera's sampling rate allows it to record an image frame at about 90% of the frequency that the tires are spinning. That is, the tire is spinning fast enough that it rotates 90% around in between each picture the camera can take. In this case, the wheel will look like its rotated backwards by 10% of a rotation on each image. When you put these images together in a film, the tires will appear to be rotating backwards.",

        "evidence": "We applied this method to discover gender-associated words in both domains. In Table TABREF9, we present a sample of the most gender-associated nouns from the celebrity domain. Several themes emerge: for example, female celebrities seem to be more associated with appearance (“gown,” “photo,” “hair,” “look”), while male celebrities are more associated with creating content (“movie,” “film,” “host,” “director”). This echoes real-world trends: for instance, on the red carpet, actresses tend to be asked more questions about their appearance –- what brands they are wearing, how long it took to get ready, etc. –- while actors are asked questions about their careers and creative processes (as an example, see BIBREF31).\nTable TABREF9 also includes some of the most gender-associated verbs and adjectives from the professor domain. Female CS professors seem to be praised for being communicative and personal with students (“respond,” “communicate,” “kind,” “caring”), while male CS professors are recognized for being knowledgeable and challenging the students (“teach,”, “challenge,” “brilliant,” “practical”). These trends are well-supported by social science literature, which has found that female teachers are praised for “personalizing” instruction and interacting extensively with students, while male teachers are praised for using “teacher as expert” styles that showcase mastery of material BIBREF32.\nThese findings establish that there are clear differences in how people talk about women and men – even with Bonferroni correction, there are still over 500 significantly gender-associated nouns, verbs, and adjectives in the celebrity domain and over 200 in the professor domain. Furthermore, the results in both domains align with prior studies and real world trends, which validates that our methods can capture meaningful patterns and innovatively provide evidence at the large-scale. This analysis also hints that it can be helpful to abstract from words to topics to recognize higher-level patterns of gender associations, which motivates our next section on clustering.\nTable TABREF11 displays a sample of our results – we find that the clusters are coherent in context and the labels seem reasonable. In the next section, we discuss human evaluations that we conducted to more rigorously evaluate the output, but first we discuss the value of these methods toward analysis.\nAt the word-level, we hypothesized that in the celebrity domain, women were more associated with appearance and men with creating content. Now, we can validate those hypotheses against labeled clusters – indeed, there is a cluster labeled clothing that is 100% female (i.e. 100% words are female-associated), and a 80% male cluster labeled movie. Likewise, in the professor domain, we had guessed that women are associated with communication and men with knowledge, and there is a 100% female cluster labeled communication and a 89% male cluster labeled cognition. Thus, cluster labeling proves to be very effective at pulling out the patterns that we believed we saw at the word-level, but could not formally validate.\nThe clusters we mentioned so far all lean heavily toward one gender association or the other, but some clusters are interesting precisely because they do not lean heavily – this allows us to see where semantic groupings do not align exactly with gender association. For example, in the celebrity domain, there is a cluster labeled lover that has a mix of female-associated words (“boyfriend,” “beau,” “hubby”) and male-associated words (“wife,” “girlfriend”). Jointly leveraging cluster labels and gender associations allows us to see that in the semantic context of having a lover, women are typically associated with male figures and men with female figures, which reflects heteronormativity in society.\nAt the word-level, we hypothesized that in the celebrity domain, women were more associated with appearance and men with creating content.",

        "evidence": "Pablo Ruiz Picasso (25 October 1881 – 8 April 1973) was a Spanish painter, sculptor, printmaker, ceramicist and theatre designer who spent most of his adult life in France. One of the most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon (1907), and the anti-war painting Guernica (1937), a dramatic portrayal of the bombing of Guernica by German and Italian air forces during the Spanish Civil War.\n\nPicasso demonstrated extraordinary artistic talent in his early years, painting in a naturalistic manner through his childhood and adolescence. During the first decade of the 20th century, his style changed as he experimented with different theories, techniques, and ideas. After 1906, the Fauvist work of the older artist Henri Matisse motivated Picasso to explore more radical styles, beginning a fruitful rivalry between the two artists, who subsequently were often paired by critics as the leaders of modern art.\n\nPicasso's work is often categorized into periods. While the names of many of his later periods are debated, the most commonly accepted periods in his work are the Blue Period (1901–1904), the Rose Period (1904–1906), the African-influenced Period (1907–1909), Analytic Cubism (1909–1912), and Synthetic Cubism (1912–1919), also referred to as the Crystal period. Much of Picasso's work of the late 1910s and early 1920s is in a neoclassical style, and his work in the mid-1920s often has characteristics of Surrealism. His later work often combines elements of his earlier styles.\n\nExceptionally prolific throughout the course of his long life, Picasso achieved universal renown and immense fortune for his revolutionary artistic accomplishments, and became one of the best-known figures in 20th-century art.",

        "question": "How do the authors perform classification experiments?",
        "answer": "The authors performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty",
        "evidence": "We performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty; this also allows us to compare results with our baseline. We applied a standardization of the features and we used the default configuration for parameters as described in scikit-learn package BIBREF33. We also tested other classifiers (such as K-Nearest Neighbors, Support Vector Machines and Random Forest) but we omit results as they give comparable performances. We remark that our goal is to show that a very simple machine learning framework, with no parameter tuning and optimization, allows for accurate results with our network-based approach.\nWe used the following evaluation metrics to assess the performances of different classifiers (TP=true positives, FP=false positives, FN=false negatives):\nPrecision = $\\frac{TP}{TP+FP}$, the ability of a classifier not to label as positive a negative sample.\nRecall = $\\frac{TP}{TP+FN}$, the ability of a classifier to retrieve all positive samples.\nF1-score = $2 \\frac{\\mbox{Precision} \\cdot \\mbox{Recall}}{\\mbox{Precision} + \\mbox{Recall}}$, the harmonic average of Precision and Recall.\nArea Under the Receiver Operating Characteristic curve (AUROC); the Receiver Operating Characteristic (ROC) curve BIBREF34, which plots the TP rate versus the FP rate, shows the ability of a classifier to discriminate positive samples from negative ones as its threshold is varied; the AUROC value is in the range $[0, 1]$, with the random baseline classifier holding AUROC$=0.5$ and the ideal perfect classifier AUROC$=1$; thus larger AUROC values (and steeper ROCs) correspond to better classifiers.\nIn particular we computed so-called macro average–simple unweighted mean–of these metrics evaluated considering both labels (disinformation and mainstream). We employed stratified shuffle split cross validation (with 10 folds) to evaluate performances.\nFinally, we partitioned networks according to the total number of unique users involved in the sharing, i.e. the number of nodes in the aggregated network represented with a single-layer representation considering together all layers and also pure tweets. A breakdown of both datasets according to size class (and political biases for the US scenario) is provided in Table 1 and Table 2.\nIn Table 3 we first provide classification performances on the US dataset for the LR classifier evaluated on the size class described in Table 1. We can observe that in all instances our methodology performs better than a random classifier (50% AUROC), with AUROC values above 85% in all cases.\nFor what concerns political biases, as the classes of mainstream and disinformation networks are not balanced (e.g., 1,292 mainstream and 4,149 disinformation networks with right bias) we employ a Balanced Random Forest with default parameters (as provided in imblearn Python package BIBREF35). In order to test the robustness of our methodology, we trained only on left-biased networks or right-biased networks and tested on the entire set of sources (relative to the US dataset); we provide a comparison of AUROC values for both biases in Figure 4. We can notice that our multi-layer approach still entails significant results, thus showing that it can accurately distinguish mainstream news from disinformation regardless of the political bias. We further corroborated this result with additional classification experiments, that show similar performances, in which we excluded from the training/test set two specific sources (one at a time and both at the same time) that outweigh the others in terms of data samples–respectively \"breitbart.com\" for right-biased sources and \"politicususa.com\" for left-biased ones.\nWe performed classification experiments on the Italian dataset using the LR classifier and different size classes (we excluded $[1000, +\\infty )$ which is empty); we show results for different evaluation metrics in Table 3. We can see that despite the limited number of samples (one order of magnitude smaller than the US dataset) the performances are overall in accordance with the US scenario. As shown in Table 4, we obtain results which are much better than our baseline in all size classes (see Table 4):\nIn the US dataset our multi-layer methodology performs much better in all size classes except for large networks ($[1000, +\\infty )$ size class), reaching up to 13% improvement on smaller networks ($[0, 100)$ size class);\nIn the IT dataset our multi-layer methodology outperforms the baseline in all size classes, with the maximum performance gain (20%) on medium networks ($[100, 1000)$ size class); the baseline generally reaches bad performances compared to the US scenario.\nOverall, our performances are comparable with those achieved by two state-of-the-art deep learning models for \"fake news\" detection BIBREF9BIBREF36.\nIn order to understand the impact of each layer on the performances of classifiers, we performed additional experiments considering separately each layer (we ignored T and U features relative to pure tweets). In Table 5 we show metrics for each layer and all size classes, computed with a 10-fold stratified shuffle split cross validation, evaluated on the US dataset; in Figure 5 we show AUROC values for each layer compared with the general multi-layer approach. We can notice that both Q and M layers alone capture adequately the discrepancies of the two distinct news domains in the United States as they obtain good results with AUROC values in the range 75%-86%; these are comparable with those of the multi-layer approach which, nevertheless, outperforms them across all size classes.\nWe obtained similar performances for the Italian dataset, as the M layer obtains comparable performances w.r.t multi-layer approach with AUROC values in the range 72%-82%. We do not show these results for sake of conciseness.\nWe further investigated the importance of each feature by performing a $\\chi ^2$ test, with 10-fold stratified shuffle split cross validation, considering the entire range of network sizes $[0, +\\infty )$. We show the Top-5 most discriminative features for each country in Table 6.\nWe can notice the exact same set of features (with different relative orderings in the Top-3) in both countries; these correspond to two global network propertie–LWCC, which indicates the size of the largest cascade in the layer, and SCC, which correlates with the size of the network–associated to the same set of layers (Quotes, Retweets and Mentions).\nWe further performed a $\\chi ^2$ test to highlight the most discriminative features in the M layer of both countries, which performed equally well in the classification task as previously highlighted; also in this case we focused on the entire range of network sizes $[0, +\\infty )$. Interestingly, we discovered exactly the same set of Top-3 features in both countries, namely LWCC, SCC and DWCC (which indicates the depth of the largest cascade in the layer).\nAn inspection of the distributions of all aforementioned features revealed that disinformation news exhibit on average larger values than mainstream news.\nWe can qualitatively sum up these results as follows:\nSharing patterns in the two news domains exhibit discrepancies which might be country-independent and due to the content that is being shared.\nInteractions in disinformation sharing cascades tends to be broader and deeper than in mainstream news, as widely reported in the literature BIBREF8BIBREF2BIBREF7.\nUsers likely make a different usage of mentions when sharing news belonging to the two domains, consequently shaping different sharing patterns.\nSimilar to BIBREF9, we carried out additional experiments to answer the following question: how long do we need to observe a news spreading on Twitter in order to accurately classify it as disinformation or mainstream?\nWith this goal, we built several versions of our original dataset of multi-layer networks by considering in turn the following lifetimes: 1 hour, 6 hours, 12 hours, 1 day, 2 days, 3 days and 7 days; for each case, we computed the global network properties of the corresponding network and evaluated the LR classifier with 10-fold cross validation, separately for each lifetime (and considering always the entire set of networks). We show corresponding AUROC values for both US and IT datasets in Figure 6.\nWe can see that in both countries news diffusion networks can be accurately classified after just a few hours of spreading, with AUROC values which are larger than 80% after only 6 hours of diffusion. These results are very promising and suggest that articles pertaining to the two news domains exhibit discrepancies in their sharing patterns that can be timely exploited in order to rapidly detect misleading items from factual information.\nWe performed classification experiments using a basic off-the-shelf classifier, namely Logistic Regression (LR) with L2 penalty; this also allows us to compare results with our baseline.",

        "evidence": "Waseem et al. BIBREF1 were the first who collected hateful tweets and categorized them into being sexist, racist or neither. However, they did not provide specific definitions for each category. Jha and Mamidi BIBREF0 focused on just sexist tweets and proposed two categories of hostile and benevolent sexism. However, these categories were general as they ignored other types of sexism happening in social media. Sharifirad S. and Matwin S. BIBREF2 proposed complimentary categories of sexist language inspired from social science work. They categorized the sexist tweets into the categories of indirect harassment, information threat, sexual harassment and physical harassment. In the next year the same authors proposed BIBREF3 a more comprehensive categorization of online harassment in social media e.g. twitter into the following categories, indirect harassment, information threat, sexual harassment, physical harassment and not sexist.\nFor the detection of hate speech in social media like twitter, many approaches have been proposed. Jha and Mamidi BIBREF0 tested support vector machine, bi-directional RNN encoder-decoder and FastText on hostile and benevolent sexist tweets. They also used SentiWordNet and subjectivity lexicon on the extracted phrases to show the polarity of the tweets. Sharifirad et al. BIBREF4 trained, tested and evaluated different classification methods on the SemEval2018 dataset and chose the classifier with the highest accuracy for testing on each category of sexist tweets to know the mental state and the affectual state of the user who tweets in each category. To overcome the limitations of small data sets on sexist speech detection, Sharifirad S. et al. BIBREF5 have applied text augmentation and text generation with certain success. They have generated new tweets by replacing words in order to increase the size of our training set. Moreover, in the presented text augmentation approach, the number of tweets in each class remains the same, but their words are augmented with words extracted from their ConceptNet relations and their description extracted from Wikidata. Zhang et al. BIBREF6 combined convolutional and gated recurrent networks to detect hate speech in tweets. Others have proposed different methods, which are not based on deep learning. Burnap and Williams BIBREF7 used Support Vector Machines, Random Forests and a meta-classifier to distinguish between hateful and non-hateful messages. A survey of recent research in the field is presented in BIBREF8. For the problem of the hate speech detection a few approaches have been proposed that are based on the Attention mechanism. Pavlopoulos et al. BIBREF9 have proposed a novel, classification-specific attention mechanism that improves the performance of the RNN further for the detection of abusive content in the web. Xie et al. BIBREF10 for emotion intensity prediction, which is a similar problem to ours, have proposed a novel attention mechanism for CNN model that associates attention-based weights for every convolution window. Park and Fung BIBREF11 transformed the classification into a 2-step problem, where abusive text first is distinguished from the non-abusive, and then the class of abuse (Sexism or Racism) is determined. However, while the first part of the two step classification performs quite well, it falls short in detecting the particular class the abusive text belongs to. Pitsilis et al. BIBREF12 have proposed a detection scheme that is an ensemble of RNN classifiers, which incorporates various features associated with user related information, such as the users’ tendency towards racism or sexism\nIn the next year the same authors proposed [4] a more comprehensive categorization of online harassment in social media e.g. twitter into the following categories, indirect harassment, information threat, sexual harassment, physical harassment and not sexist.",

        "question": "Intuitively, why do self-supervised models forget less than supervised models?",
        "answer": "We provide more insights and empirical evidence on why SSLmodels forget less than SL models, from the perspective of the sharpness of minima in the loss landscape.\nFlat minima in the loss landscape are the minima in which the change of losses is slow in its neighborhood. Note that the models having flat minima in the loss landscape tend to exhibit an impressive generalization ability [1]. When starting with flat minima, we expect that learning new chunks will have a minor effect on the performance of existing chunks, as escaping the wide basin is difficult. Therefore, we hypothesize that SSL encourages the model to seek out more flat minima, which increases SSL's resistance to catastrophic forgetting of previous data chunks, further leading to smaller performance gaps between SSL-ST and SSL-JT on downstream tasks.\nTo verify this hypothesis, we conduct experiments to compare the sharpness of minima between SL and SSL models. Specifically, we measure the sharpness via a standard sharpness metric in [2]. We also conduct model interpolation between sequential models to visualize the linear path in the loss landscape for both SL and SSL models. The experimental results in Section 5.3 demonstrate that SSL indeed discovers the more flat minima compared to SL, which verifies our hypothesis and provides an explanation for why SSL suffers less forgetting than SL. More details about sharpness analysis can be found in Sec 5.3 and Appendix C.4",
        "evidence": "We first provide more details of the sharpness metric in Eq. (2). We compute the sharpness on the respective chunk A for different types of streaming data in ImageNet. Considering that the function f is not differentiable, we sample θ 0 from C and run 50 times to take the minimal accuracy. For computational efficiency, we randomly sample 0.1M data points to perform kNN classification with k=200. We need to clarify that we cannot make comparisons of sharpness values across different sequential settings. Because in different settings, the loss values are calculated on different data samples and the kNN classification tasks are different such as the number of classes to be classified. Therefore, we can only compare the sharpness value between SL and SSL models trained and tested on the same streaming data. Concretely, for the instance incremental sequence, chunk A contains IID samples from ImageNet-1K, classified into 1000 classes. For the random class incremental sequence, chunk A contains 250 random classes from ImageNet-1K, classified into 250 classes. For the distant class incremental sequence, chunk A contains 250 semantically similar classes from ImageNet-1K, classified into 250 classes. We note that in Table 4, the instance incremental sequence has the worst sharpness metric value compared to the other two types of streaming data. This observation is easy to understand. The classification task with 1,000 classes on instance incremental data is more challenging than both classification tasks with only 250 classes on the other two types of streaming data. Therefore, the sharpness value of instance incremental data is the highest. Different from the sharpness experiments, transfer learning experiments evaluate the performance of models on downstream tasks. Therefore, there is no contradiction between the observations from both kinds of experiments. For flatness visualization, we show the normalized loss along the specified path by performing linearly interpolation between the model after chunk 1 and the model after chunk 2 for different splits, as shown in Figure 17. We can see that compared to SL, loss change is slower for SSL along the linear path, which reflects SSL’s superiority in terms of flatness. Specifically, the negative value in the SSL curve means that the performance of SSL continuously improves along the path for instance incremental learning.",

However, the usefulness of Flickr for characterizing the natural environment, which is the focus of this paper, is less well-understood.\nMany recent studies have highlighted that Flickr tags capture valuable ecological information, which can be used as a complementary source to more traditional sources. To date, however, ecologists have mostly used social media to conduct manual evaluations of image content with little automated exploitation of the associated tags BIBREF4 , BIBREF5 , BIBREF6 . One recent exception is BIBREF7 , where bag-of-words representations derived from Flickr tags were found to give promising result for predicting a range of different environemental phenomena.\nOur main hypothesis in this paper is that by using vector space embeddings instead of bag-of-words representations, the ecological information which is implicitly captured by Flickr tags can be utilized in a more effective way. Vector space embeddings are representations in which the objects from a given domain are encoded using relatively low-dimensional vectors. They have proven useful in natural language processing, especially for encoding word meaning BIBREF8 , BIBREF9 , and in machine learning more generally. In this paper, we are interested in the use of such representations for modelling geographic locations. Our main motivation for using vector space embeddings is that they allow us to integrate the textual information we get from Flickr with available structured information in a very natural way. To this end, we rely on an adaptation of the GloVe word embedding model BIBREF9 , but rather than learning word vectors, we learn vectors representing locations. Similar to how the representation of a word in GloVe is determined by the context words surrounding it, the representation of a location in our model is determined by the tags of the photos that have been taken near that location. To incorporate numerical features from structured environmental datasets (e.g. average temperature), we associate with each such feature a linear mapping that can be used to predict that feature from a given location vector. This is inspired by the fact that salient properties of a given domain can often be modelled as directions in vector space embeddings BIBREF10 , BIBREF11 , BIBREF12 . Finally, evidence from categorical datasets (e.g. land cover types) is taken into account by requiring that locations belonging to the same category are represented using similar vectors, similar to how semantic types are sometimes modelled in the context of knowledge graph embedding BIBREF13 .\nWhile our point-of-departure is a standard word embedding model, we found that the off-the-shelf GloVe model performed surprisingly poorly, meaning that a number of modifications are needed to achieve good results. Our main findings are as follows. First, given that the number of tags associated with a given location can be quite small, it is important to apply some kind of spatial smoothing, i.e. the importance of a given tag for a given location should not only depend on the occurrences of the tag at that location, but also on its occurrences at nearby locations. To this end, we use a formulation which is based on spatially smoothed version of pointwise mutual information. Second, given the wide diversity in the kind of information that is covered by Flickr tags, we find that term selection is in some cases critical to obtain vector spaces that capture the relevant aspects of geographic locations. For instance, many tags on Flickr refer to photography related terms, which we would normally not want to affect the vector representation of a given location. Finally, even with these modifications, vector space embeddings learned from Flickr tags alone are sometimes outperformed by bag-of-words representations. However, our vector space embeddings lead to substantially better predictions in cases where structured (scientific) information is also taken into account. In this sense, the main value of using vector space embeddings in this context is not so much about abstracting away from specific tag usages, but rather about the fact that such representations allow us to integrate numerical and categorical features in a much more natural way than is possible with bag-of-words representations.\nThe remainder of this paper is organized as follows. In the next section, we provide a discussion of existing work. Section SECREF3 then presents our model for embedding geographic locations from Flickr tags and structured data. Next, in Section SECREF4 we provide a detailed discussion about the experimental results. Finally, Section SECREF5 summarizes our conclusions.\nTo this end, we use a formulation which is based on spatially smoothed version of pointwise mutual information.",

        "evidence": "The United States has 63 national parks, which are congressionally designated protected areas operated by the National Park Service, an agency of the Department of the Interior. National parks are designated for their natural beauty, unique geological features, diverse ecosystems, and recreational opportunities, typically \"because of some outstanding scenic feature or natural phenomena.\" While legislatively all units of the National Park System are considered equal with the same mission, national parks are generally larger and more of a destination, and hunting and extractive activities are prohibited. National monuments, on the other hand, are also frequently protected for their historical or archaeological significance. Eight national parks (including six in Alaska) are paired with a national preserve, areas with different levels of protection that are administered together but considered separate units and whose areas are not included in the figures below. The 424 units of the National Park System can be broadly referred to as national parks, but most have other formal designations.\n\nThirty states have national parks, as do the territories of American Samoa and the U.S. Virgin Islands. The state with the most national parks is California with nine, followed by Alaska with eight, Utah with five, and Colorado with four. The largest national park is Wrangell–St. Elias in Alaska: at over 8 million acres (32,375 km2), it is larger than each of the nine smallest states. The next three largest parks are also in Alaska. The smallest park is Gateway Arch National Park, Missouri, at 91 acres (0.37 km2). The total area protected by national parks is approximately 52.2 million acres (211,000 km2), for an average of 829 thousand acres (3,350 km2) but a median of only 208 thousand acres (840 km2).\n\nThe national parks set a visitation record in 2017, with more than 84 million visitors and set a further record in 2018 with a 0.1% increase. Great Smoky Mountains National Park in North Carolina and Tennessee has been the most-visited park since 1944, and had over 14 million visitors in 2021. In contrast, only about 7,000 people visited the remote Gates of the Arctic National Park and Preserve in Alaska in 2021.",

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nWe provide empirical support for the design principle of NMT architectures: essential inductive bias (e.g., language characteristics) should be considered for model design.",

        "question": "Who is asked to annotate their sentences for grammaticality, providing a human comparison?",
        "answer": "Proficient German speakers.",
        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nWe ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison.",

They became part of the United Nations Trust Territory of the Pacific Islands (TTPI) in 1947, administered by the United States as U.N. trustee. The other constituents of the TTPI were Palau, the Federated States of Micronesia and the Marshall Islands. Following failed efforts in the 1950s and 1960s to reunify Guam and the Northern Marianas, a covenant to establish the Northern Mariana Islands as a commonwealth in political union with the United States was negotiated by representatives of both political bodies; it was approved by Northern Mariana Islands voters in 1975, and came into force on March 24, 1976. In accordance with the covenant, the Northern Mariana Islands constitution partially took effect on January 9, 1978, and became fully effective on November 4, 1986.

        "evidence": "With the gathered comments, we reconstructed the original conversation trees, from the original post, the root, to the leaves, when they were available and selected a subset to annotated. For annotation purposes, we created snippets of conversations as the ones shown in Example 1 and Example 2 consisting of the parent of the suspected trolling event, the suspected trolling event comment, and all of the direct responses to the suspected trolling event. We added an extra constraint that the parent of the suspected trolling event should also be part of the direct responses, we hypothesize that if the suspected trolling event is indeed trolling, its parent should be the object of its trolling and would have a say about it. We recognize that this limited amount of information is not always sufficient to recover the original message conveyed by all of the participants in the snippet, and additional context would be beneficial. However, the trade off is that snippets like this allow us to make use of Amazon Mechanical Turk (AMT) to have the dataset annotated, because it is not a big burden for a “turker” to work on an individual snippet in exchange for a small pay, and expedites the annotation process by distributing it over dozens of people. Specifically, for each snippet, we requested three annotators to label the four aspects previously described. Before annotating, we set up a qualification test along with borderline examples to guide them in process and align them with our criteria. The qualification test turned out to be very selective since only 5% of all of the turkers that attempted it passed the exam. Our dataset consists of 1000 conversations with 5868 sentences and 71033 tokens. The distribution over the classes per trolling aspect is shown in the table TABREF24 in the column “Size”.\nFor annotation purposes, we created snippets of conversations as the ones shown in Example 1 and Example 2 consisting of the parent of the suspected trolling event, the suspected trolling event comment, and all of the direct responses to the suspected trolling event.\nHowever, the trade off is that snippets like this allow us to make use of Amazon Mechanical Turk (AMT) to have the dataset annotated, because it is not a big burden for a “turker” to work on an individual snippet in exchange for a small pay, and expedites the annotation process by distributing it over dozens of people.

        "evidence": "Neural abstractive summarization systems trained by maximizing the likelihood of a reference summary (MLE) given its source document have been shown to generate plausible summaries with high lexical overlap with the references. However, human analyses and automatic evaluations show that state-of-the-art neural models, trained on widely used XSUM and CNN/DM datasets, tend to hallucinate information with high frequency. For instance, by performing human evaluations on 2250 model generated summaries from CNN/DM and XSUM datasets, found that 60% of the summaries contained at least one factual error. The hallucinations are broadly classified as extrinsic, when a model adds information that is not present in the source document, and intrinsic, when the model distorts information present in the source document into a factually incorrect representation. The type and degree of a model's hallucinations correlate with the quality of training data. As noted by, models trained on the XSum data, which include extrinsic hallucinations in reference summaries, tend to generate a higher proportion of extrinsic hallucination as compared to models trained on the cleaner CNN/DM dataset.\nIn this paper, we propose the Mixture of Factual Experts (MoFE), a simple framework that applies an ensemble of factual experts to control hallucinations in summarization systems. We define factual expert as a model that generates summaries with certain desirable factual qualities (e.g. fewer extrinsic hallucinations). Each constituent factual expert in MoFE is trained to target a unique type of factual quality. The training of the experts is motivated by two broad observations. First, the data on which the model is trained may influence the factual consistency of the model. Therefore, we employ a data pre-processing step that filters training samples such that the references exhibit the desirable factual qualities. Second, the maximum-likelihood loss function may overlook factual consistency. Therefore we employ reinforcement learning (RL) to train a model using explicit signals of factual consistency. Further, we augment standard reward-based RL loss with a KL divergence loss between the expert and pre-trained model's distributions on pivot summary 1 to prevent the former from deviating too far from the latter. We propose to choose the pivot summary depending on the number of factual errors in training samples. When all samples in the training data possess desirable factual consistency, we use reference as the pivot summary. On the contrary, if training data contains factual errors, we use the expert-sampled summary as the pivot. We show the schematic view of MoFE in Figure.\nWe use entity overlap and dependency arc entailment (DAE) accuracy metrics as measures of extrinsic and intrinsic hallucinations, respectively, and accordingly use both metrics to define rewards for training experts targeting both types of hallucination. Entity overlap evaluates the number of entities in summary that are absent from the source document and is a direct measure of extrinsic hallucination. Intrinsic hallucination, on the other hand, is broader and includes errors such as incorrect predicates or their arguments, coreference errors, discourse link errors, etc.. Since DAE accuracy measures the fine-grained entailment relations at the dependency arc level, we consider it a reasonable proxy for measuring intrinsic hallucinations. Additionally, given that experts trained on both entity overlap and DAE metrics try to improve precision and are prone to reducing factual recall, MoFE also includes an entity recall-based expert. Subsequently, we combine the above three experts through logits and weights ensembling.\nWe evaluate our MoFE on the two benchmark abstractive summarization datasets, XSUM and CNN/DM. We use a diverse set of metrics, including entailment, entity overlap, and question answering (QA)-based metrics to measure factual errors. We find that MoFE models strongly outperform the state-of-the-art BART model, obtaining up to ∼ 6% absolute improvement on factual consistency metric (summary-level DAE accuracy) used to train experts, with marginal degradation (< 0.74) on ROUGE scores. Further, MoFE performs better than BART on two QAbased metrics (FEQA and QuestEval) on XSUM dataset. However, on CNN/DM, we find contrasting results, MoFE improves on QuestEval but not on FEQA, which may be attributed to the differences in questions generated by the two systems. Finally, we use the SummVis tool to analyze MoFE and BART models' summaries on the XSUM dataset. We find that, relatively, MoFE reduces factual errors, some of which are clear cases of hallucinations while others may represent world knowledge (e.g. replacing the UK with the United Kingdom). In the appendix, we show some example cases where MoFE-generated summary removed, added, or ignored factual errors in the BART-generated summary.\nTherefore, we use DAE accuracy3 to identify cases of intrinsic hallucinations, both during training and evaluation.****First, we find that ensembling multiple BART models improves ROUGE scores and NER recall, but not factual consistency metrics defined by DAE accuracy and NER precision.****Separately, we also evaluate the MoFE on BERTScore (Zhang et al., 2019b) precision (BS-P) and recall (BS-R) 296 with respect to source and two question answer-based evaluation metrics, FEQA and QuestEval.",

Risotto, unlike other rice dishes, requires constant care and attention. The rice is not to be pre-rinsed, boiled, or drained, as washing would remove much of the starch required for a creamy texture. \n The rice is first cooked briefly in a soffritto of onion and butter or olive oil to coat each grain in a film of fat, called tostatura; white wine is added and must be absorbed by the grains. When it has been absorbed, the heat is raised to medium-high, and boiling stock is gradually added in small amounts while stirring constantly. The constant stirring, with only a small amount of liquid present, forces the grains to rub against each other and release the starch from the outside of the grains into the surrounding liquid, creating a smooth creamy-textured mass. When the rice is cooked the pot is taken off the heat for mantecatura, vigorously beating in refrigerated balls of grated parmesan cheese and butter, to make the texture as creamy and smooth as possible. It may be removed from the heat a few minutes earlier and left to cook with its residual heat.\nProperly cooked risotto is rich and creamy even if no cream is added due to the starch in the grains. It has some resistance or bite (al dente) and separate grains. The traditional texture is fairly fluid, or all'onda (\"wavy\" or \"flowing in waves\"). It is served on flat dishes and should easily spread out but not have excess watery liquid around the perimeter.

        "answer": "Yes, it does.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nWe also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance.",

        "evidence": "The Netherlands (Dutch: Nederland [ˈneːdərlɑnt] (listen)), informally Holland, is a country located in northwestern Europe with overseas territories in the Caribbean. It is the largest of four constituent countries of the Kingdom of the Netherlands. The Netherlands consists of twelve provinces; it borders Germany to the east, and Belgium to the south, with a North Sea coastline to the north and west. It shares maritime borders with the United Kingdom, Germany and Belgium in the North Sea. The country's official language is Dutch, with West Frisian as a secondary official language in the province of Friesland. Dutch, English and Papiamento are official in the Caribbean territories.\n\nThe four largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague and Utrecht. Amsterdam is the country's most populous city and the nominal capital. The Hague holds the seat of the States General, Cabinet and Supreme Court. The Port of Rotterdam is the busiest seaport in Europe. Schiphol is the busiest airport in the Netherlands, and the third busiest in Europe. The Netherlands is a founding member of the European Union, Eurozone, G10, NATO, OECD, and WTO, as well as a part of the Schengen Area and the trilateral Benelux Union. It hosts several intergovernmental organisations and international courts, many of which are centred in The Hague.\n\nNetherlands literally means \"lower countries\" in reference to its low elevation and flat topography, with nearly 26% falling below sea level. Most of the areas below sea level, known as polders, are the result of land reclamation that began in the 14th century. In the Republican period, which began in 1588, the Netherlands entered a unique era of political, economic, and cultural greatness, ranked among the most powerful and influential in Europe and the world; this period is known as the Dutch Golden Age. During this time, its trading companies, the Dutch East India Company and the Dutch West India Company, established colonies and trading posts all over the world.\n\nWith a population of 17.8 million people, all living within a total area of 41,850 km2 (16,160 sq mi)—of which the land area is 33,500 km2 (12,900 sq mi)—the Netherlands is the 16th most densely populated country in the world and the second-most densely populated country in the European Union, with a density of 531 people per square kilometre (1,380 people/sq mi). Nevertheless, it is the world's second-largest exporter of food and agricultural products by value, owing to its fertile soil, mild climate, intensive agriculture, and inventiveness.\n\nThe Netherlands has been a parliamentary constitutional monarchy with a unitary structure since 1848. The country has a tradition of pillarisation and a long record of social tolerance, having legalised abortion, prostitution and euthanasia, along with maintaining a liberal drug policy. The Netherlands allowed women's suffrage in 1919 and was the first country to legalise same-sex marriage in 2001. Its mixed-market advanced economy has the thirteenth-highest per capita income globally.",

It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. Though no longer at the geographic center of the federal district, the Capitol forms the origin point for the street-numbering system of the district as well as its four quadrants.\n\nCentral sections of the present building were completed in 1800. These were partly destroyed in the 1814 Burning of Washington, then were fully restored within five years. The building was enlarged in the 1850s by extending the wings for the chambers for the bicameral legislature, the House of Representatives in the south wing and the Senate in the north wing. The massive dome was completed around 1866 just after the American Civil War. Like the principal buildings of the executive and judicial branches, the Capitol is built in a neoclassical style and has a white exterior. Both its east and west elevations are formally referred to as fronts, though only the east front was intended for the reception of visitors and dignitaries.",

        "answer": "Cricket is one of the most popular sports in Asian countries. One of the worlds biggest cricket teams are India. The reason for so much popularity is multifold. Top reason is when English invaded South east asia they brought this game to the continent. Originally this game was only played by upper class, and later adopted by other classes as well. To play cricket you need one bat and one ball. Bat will be made up of wood and ball can be either tennis ball or hard ball which is made up of leather. You need a wicket which is 3 sticks and 2 bails on top. One person throws the ball and other person try to protect his wickets with the bat. The length of the wicket is 22 yards. Batsman can hit the ball for runs. To make runs, there are two ways. First is to hit the boundary, which can fetch either 4 or 6 runs. Second way is to run between the wickets and make as many runs as you can. There are other ways to get runs as well, like if its a wide ball or no ball. For a team to win a match, they either have to make more runs then the other team or get them all out before they can make more runs then them. Most popular cricket format is T20, then One day internationals (ODI) and then Test matches. T20 is the shortest form and have 20 overs and 2 innings. ODI has 50 overs and 2 innings. Whereas Test is the longest format and can carry on for 5 days, with 90 overs every day and up to 2 innings per team. Both men and women play cricket. Worlds biggest cricket league is IPL in india. PSL in Pakistan is considered as the second best league. There are 2 cricket worldcups. T20 worldcup is played every 2 years and ODI worldcup is played every 4 years. There is also World Test and ODI championship as well, which is player every year.",

        "question": "What insight does this work provide?",
        "answer": "The insight about the types of computations that sequential neural networks can perform through the lens of formal language theory.",
        "evidence": "In recent years, neural networks have achieved tremendous success on a variety of natural language processing (NLP) tasks. Neural networks employ continuous distributed representations of linguistic data, which contrast with classical discrete methods. While neural methods work well, one of the downsides of the distributed representations that they utilize is interpretability. It is hard to tell what kinds of computation a model is capable of, and when a model is working, it is hard to tell what it is doing.\nThis work aims to address such issues of interpretability by relating sequential neural networks to forms of computation that are more well understood. In theoretical computer science, the computational capacities of many different kinds of automata formalisms are clearly established. Moreover, the Chomsky hierarchy links natural language to such automata-theoretic languages BIBREF0 . Thus, relating neural networks to automata both yields insight into what general forms of computation such models can perform, as well as how such computation relates to natural language grammar.\nRecent work has begun to investigate what kinds of automata-theoretic computations various types of neural networks can simulate. BIBREF1 propose a connection between long short-term memory networks (LSTMs) and counter automata. They provide a construction by which the LSTM can simulate a simplified variant of a counter automaton. They also demonstrate that LSTMs can learn to increment and decrement their cell state as counters in practice. BIBREF2 , on the other hand, describe a connection between the gating mechanisms of several recurrent neural network (RNN) architectures and weighted finite-state acceptors.\nThis paper follows BIBREF1 by analyzing the expressiveness of neural network acceptors under asymptotic conditions. We formalize asymptotic language acceptance, as well as an associated notion of network memory. We use this theory to derive computation upper bounds and automata-theoretic characterizations for several different kinds of recurrent neural networks section:rnns, as well as other architectural variants like attention section:attention and convolutional networks (CNNs) section:cnns. This leads to a fairly complete automata-theoretic characterization of sequential neural networks.\nIn section:experiments, we report empirical results investigating how well these asymptotic predictions describe networks with continuous activations learned by gradient descent. In some cases, networks behave according to the theoretical predictions, but we also find cases where there is gap between the asymptotic characterization and actual network behavior.\nStill, discretizing neural networks using an asymptotic analysis builds intuition about how the network computes. Thus, this work provides insight about the types of computations that sequential neural networks can perform through the lens of formal language theory. In so doing, we can also compare the notions of grammar expressible by neural networks to formal models that have been proposed for natural language grammar.\nThus, this work provides insight about the types of computations that sequential neural networks can perform through the lens of formal language theory.",

Therefore, daylight savings was originally instituted to facilitate a farmer's workday so that much of the working hours could coincide with the hours where there was more daylight (daylight begins is later in the spring). Since then; however, the U.S. economy has become less agriculturally based and also with technological advancements that have drastically impacted American work patterns, the need to follow daylight windows has reduced dramatically. While daylight savings still allows many Americans to spend their working hours during the daylight, there is the popular opinion that daylight savings should no longer be observed in the United States, especially with the confusion that comes with changing hours during the spring and fall.

These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train.",

        "question": "What information do they consider exploiting to build a model?",
        "answer": "The sentiment information towards topics from archives of political debates.",
        "evidence": "The ideological leanings of a person within the left-right political spectrum are often reflected by how one feels about different topics and by means of preferences among various choices on particular issues. For example, a left-leaning person would prefer nationalization and state control of public services (such as healthcare) where privatization would be often preferred by people that lean towards the right. Likewise, a left-leaning person would often be supportive of immigration and will often talk about immigration in a positive manner citing examples of benefits of immigration on a country's economy. A right-leaning person, on the other hand, will often have a negative opinion about immigration.\nMost of the existing works on political ideology detection from text have focused on utilizing bag-of-words and other syntactic features to capture variations in language use BIBREF0 , BIBREF1 , BIBREF2 . We propose an alternative mechanism for political ideology detection based on sentiment analysis. We posit that adherents of a political ideology generally have similar sentiment toward specific topics (for example, right wing followers are often positive towards free markets, lower tax rates, etc.) and thus, a political ideology can be represented by a characteristic sentiment distribution over different topics (Section SECREF3 ). This topic-specific sentiment representation of a political ideology can then be used for automatic ideology detection by comparing the topic-specific sentiments as expressed by the content in a document (news article, magazine article, collection of social media posts by a user, utterances in a conversation, etc.).\nIn order to validate our hypothesis, we consider exploiting the sentiment information towards topics from archives of political debates to build a model for identifying political orientation of speakers as one of right or left leaning, which corresponds to republicans and democrats respectively, within the context of US politics. This is inspired by our observation that the political leanings of debators are often expressed in debates by way of speakers' sentiments towards particular topics. Parliamentary or Senate debates often bring the ideological differences to the centre stage, though somewhat indirectly. Heated debates in such forums tend to focus on the choices proposed by the executive that are in sharp conflict with the preference structure of the opposition members. Due to this inherent tendency of parliamentary debates to focus on topics of disagreement, the sentiments exposited in debates hold valuable cues to identify the political orientation of the participants.\nWe develop a simple classification model that uses a topic-specific sentiment summarization for republican and democrat speeches separately. Initial results of experiments conducted using a widely used dataset of US Congress debates BIBREF3 are encouraging and show that this simple model compares well with classification models that employ state-of-the-art distributional text representations (Section SECREF4 ).\nIn order to validate our hypothesis, we consider exploiting the sentiment information towards topics from archives of political debates to build a model for identifying political orientation of speakers as one of right or left leaning, which corresponds to republicans and democrats respectively, within the context of US politics.",

        "question": "How is the transfer setting formulated in section 5.3?",
        "answer": "A large part of our experimental evaluation is on simulated channel variations that are commonly used for modeling communication channels. Also, these distribution changes (of varying SNR) can be quite challenging for adaptation in the small-sample setting. To the best of our knowledge, there are no real-world, publicly-available datasets suitable for this domain. Therefore, we have performed real over-the-air data collection and evaluation using a mmWave FPGA testbed (details in Appendix D.1). We plan to conduct more extensive experiments using this setup as future work for a communication-focused paper.\nIn section 5.3, we introduced distribution changes via IQ imbalance based distortions to the symbol constellation, and evaluated the adaptation performance as a function of the level of imbalance. The source domain would be the original channel, the over-the-air link between the transmitter and receiver on which the training data is collected. This source domain data is used for training the channel and the autoencoder. The target domain would be a modification of the source domain where the symbols used by the transmitter (e.g., 16-QAM) are distorted by modifying the in-phase and quadrature-phase (IQ) components of the RF signal. This causes a change in the distribution observed by the decoder, leading to a drop in performance without any adaptation. Due to the page limit, we have added details clarifying the above points in Appendix D.1 of the revised paper.",
        "evidence": "We implemented the mixture density network and communication autoencoder models using TensorFlow (Abadi et al., 2015) and TensorFlow Probability. We used the BFGS optimizer implementation available in TensorFlow Probability. The code base for our work can be found at https: //anonymous.4open.science/r/ domain_adaptation-7C0D/. All the experiments were run on a Macbook Pro laptop with 16 GB memory and 8 CPU cores. Table 4 summarizes the architecture of the encoder, MDN (channel model), and decoder neural networks. Note that the output layer of the MDN is a concatenation (denoted by ⊕) of three fully-connected layers predicting the means, variances, and mixing prior logit parameters of the Gaussian mixture. The size of the hidden layers nh was set to 100. The parameters ψ of the proposed adaptation method are initialized as follows for each component i: Ai = Id, bi = 0, Ci = Id, βi = 1, γi = 0, where Id is the d × d identity matrix. This initialization ensures that the target Gaussian mixture is always initialized with the source Gaussian mixture. The regularization constant λ in the adaptation objective was varied over 16 equally-spaced values on the log-scale (base 10) with range 10−5 to 100. The λ value and ψ corresponding to the smallest validation metric are selected as the final solution. We used the Adam optimizer (Kingma & Ba, 2015) with a fixed learning rate of 0.001, batch size of 128, and 100 epochs for training the MDN. For adaptation of the MDN using the baseline methods transfer and transfer-last-layer, Adam is used with the same learning rate for 200 epochs. The batch size is set as b = max{10, 0.1 N (t) c }, where N (t) c is number of adaptation samples in the target domain. For training the autoencoder using Algorithm 1, we found that stochastic gradient descent (SGD) with Nesterov momentum (constant 0.9), and an exponential learning rate schedule between 0.1 and 0.005 works better than Adam",

We evaluate the false-reject (FR) and false-accept (FA) tradeoff across several end-to-end models of distinct sizes and computational complexities. As can be seen in the Receiver Operating Characteristic (ROC) curves in Figure FIGREF14 , the 2 largest end-to-end models, with 2-stage training, significantly outperform the recognition quality of the much larger and complex Baseline_1850K system. More specifically, E2E_318K_2stage and E2E_700K_2stage show up to 60% relative FR rate reduction over Baseline_1850K in most test conditions. Moreover, E2E_318K_2stage uses only about 26% of the computations that Baseline_1850K uses (once normalizing their execution rates over time), but still shows significant improvements. We also explore end-to-end models at a size that, as described in BIBREF7 , is small enough, in both size and computation, to be executed continuously with very little power consumption. These 2 models, E2E_40K_1stage and E2E_40K_2stage, also explore the capacity of end-to-end training (1stage) versus encoder+decoder training (2stage). As can be appreciated in the ROC curves, 1stage training outperforms 2stage training on all conditions, but particularly on both \"clean\" environments where it gets fairly close to the performance of the baseline setup. That is a significant achievement considering E2E_40K_1stage has 2.3% the parameters and performs 3.2% the computations of Baseline_1850K. Table TABREF13 compares the recognition quality of all setups by fixing on a very low false-accept rate of 0.1 FA per hour on a dataset containing only negative (i.e. non-keyword) utterances. Thus the table shows the false-reject rates at that operating point. Here we can appreciate similar trends as those described above: the 2 largest end-to-end models outperforms the baseline across all datasets, reducing FR rate about 40% on the clean conditions and 40%-20% on the other 2 sets depending on the model size.

        "evidence": "Although the Sun appears to \"rise\" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion caused many cultures to have mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century.\nAstronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon. However, the term sunrise commonly refers to periods of time both before and after this point:\nTwilight, the period in the morning during which the sky is brightening, but the Sun is not yet visible. The beginning of morning twilight is called astronomical dawn.\nThe period after the Sun rises during which striking colors and atmospheric effects are still seen.\nThe timing of sunrise varies throughout the year and is also affected by the viewer's latitude and longitude, altitude, and time zone. These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun, and the Earth and Moon's paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise.\nIn late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.\nVariations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly.\nAccounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.",

Additionally, Amnesty International within Element AI have lately reported that many women politicians and journalists are assaulted every 30 seconds on Twitter. This is despite the Twitter policy condemning the promotion of violence against people on the basis of race, ethnicity, national origin, sexual orientation, gender identity, religious affiliation, age, disability, or serious disease. Hate speech may not represent the general opinion, yet it promotes the dehumanization of people who are typically from minority groups BIBREF0, BIBREF1 and can incite hate crime BIBREF2.\nMoreover, although people of various linguistic backgrounds are exposed to hate speech BIBREF3, BIBREF2, English is still at the center of existing work on toxic language analysis. Recently, some research studies have been conducted on languages such as German BIBREF4, Arabic BIBREF5, and Italian BIBREF6. However, such studies usually use monolingual corpora and do not contrast, or examine the correlations between online hate speech in different languages. On the other hand, tasks involving more than one language such as the hatEval task, which covers English and Spanish, include only separate classification tasks, namely (a) women and immigrants as target groups, (b) individual or generic hate and, (c) aggressive or non-aggressive hate speech.\nTreating hate speech classification as a binary task may not be enough to inspect the motivation and the behavior of the users promoting it and, how people would react to it. For instance, the hateful tweets presented in Figure FIGREF5 show toxicity directed towards different targets, with or without using slurs, and generating several types of reactions. We believe that, in order to balance between truth and subjectivity, there are at least five important aspects in hate speech analysis. Hence, our annotations indicate (a) whether the text is direct or indirect; (b) if it is offensive, disrespectful, hateful, fearful out of ignorance, abusive, or normal; (c) the attribute based on which it discriminates against an individual or a group of people; (d) the name of this group; and (e) how the annotators feel about its content within a range of negative to neutral sentiments. To the best of our knowledge there are no other hate speech datasets that attempt to capture fear out of ignorance in hateful tweets or examine how people react to hate speech. We claim that our multi-aspect annotation schema would provide a valuable insight into several linguistic and cultural differences and bias in hate speech.\nWe use Amazon Mechanical Turk to label around 13,000 potentially derogatory tweets in English, French, and Arabic based on the above mentioned aspects and, regard each aspect as a prediction task. Since in natural language processing, there is a peculiar interest in multitask learning, where different tasks can be used to help each other BIBREF7, BIBREF8, BIBREF9, we use a unified model to handle the annotated data in all three languages and five tasks. We adopt BIBREF8 as a learning algorithm adapted to loosely related tasks such as our five annotated aspects and, use the Babylon cross-lingual embeddings BIBREF10 to align the three languages. We compare the multilingual multitask learning settings with monolingual multitask, multilingual single-task, and monolingual single-task learning settings respectively. Then, we report the performance results of the different settings and discuss how each task affects the remaining ones. We release our dataset and code to the community to extend research work on multilingual hate speech detection and classification.\nSince in natural language processing, there is a peculiar interest in multitask learning, where different tasks can be used to help each other, we use a unified model to handle the annotated data in all three languages and five tasks.",

        "evidence": "Hate speech represents written or oral communication that in any way discredits a person or a group based on characteristics such as race, color, ethnicity, gender, sexual orientation, nationality, or religion BIBREF0. Hate speech targets disadvantaged social groups and harms them both directly and indirectly BIBREF1. Social networks like Twitter and Facebook, where hate speech frequently occurs, receive many critics for not doing enough to deal with it. As the connection between hate speech and the actual hate crimes is high BIBREF2, the importance of detecting and managing hate speech is not questionable. Early identification of users who promote such kind of communication can prevent an escalation from speech to action. However, automatic hate speech detection is difficult, especially when the text does not contain explicit hate speech keywords. Lexical detection methods tend to have low precision because, during classification, they do not take into account the contextual information those messages carry BIBREF3. Recently, contextual word and sentence embedding methods capture semantic and syntactic relation among the words and improve prediction accuracy.\nRecent works on combining probabilistic Bayesian inference and neural network methodology attracted much attention in the scientific community BIBREF4. The main reason is the ability of probabilistic neural networks to quantify trustworthiness of predicted results. This information can be important, especially in tasks were decision making plays an important role BIBREF5. The areas which can significantly benefit from prediction uncertainty estimation are text classification tasks which trigger specific actions. Hate speech detection is an example of a task where reliable results are needed to remove harmful contents and possibly ban malicious users without preventing the freedom of speech. In order to assess the uncertainty of the predicted values, the neural networks require a Bayesian framework. On the other hand, Srivastava et al. BIBREF6 proposed a regularization approach, called dropout, which has a considerable impact on the generalization ability of neural networks. The approach drops some randomly selected nodes from the neural network during the training process. Dropout increases the robustness of networks and prevents overfitting. Different variants of dropout improved classification results in various areas BIBREF7. Gal and Ghahramani BIBREF8 exploited the interpretation of dropout as a Bayesian approximation and proposed a Monte Carlo dropout (MCD) approach to estimate the prediction uncertainty. In this paper, we analyze the applicability of Monte Carlo dropout in assessing the predictive uncertainty.\nOur main goal is to accurately and reliably classify different forms of text as hate or non-hate speech, giving a probabilistic assessment of the prediction uncertainty in a comprehensible visual form. We also investigate the ability of deep neural network methods to provide good prediction accuracy on small textual data sets. The outline of the proposed methodology is presented in Figure FIGREF2.\nOur main contributions are:\ninvestigation of prediction uncertainty assessment to the area of text classification,\nimplementation of hate speech detection with reliability output,\nevaluation of different contextual embedding approaches in the area of hate speech,\na novel visualization of prediction uncertainty and errors of classification models.\nThe paper consists of six sections. In Section 2, we present related works on hate speech detection, prediction uncertainty assessment in text classification context, and visualization of uncertainty. In Section 3, we propose the methodology for uncertainty assessment using dropout within neural network models, as well as our novel visualization of prediction uncertainty. Section 4 presents the data sets and the experimental scenario. We discuss the obtained results in Section 5 and present conclusions and ideas for further work in Section 6.\nWe also investigate the ability of deep neural network methods to provide good prediction accuracy on small textual data sets.",

We use mixup as an additional **strong baseline**.To summarize, while comparing our approach with the recent OOD papers published at top venues, we also **create new strong baselines** for OOD such as: - mixup [4];- DNN-SN [5] and DNN-SRN [6], following the observations in SNGP that showed normalisation techniques to improve uncertainty estimation properties The recent OOD works we compare our approach with are: - **SNGP** [7], often considered one of the most effective single-model approaches.  - **DUQ** [8], as much as possible as we found it hard to make DUQ work on large experiments mostly because of training instabilities and centroid collapses. - **Deep Ensemble** [9] (often used as the gold standard); - **KFAC-LLLA** [10] (an incredibly effective Bayesian method).We mention most of these observations in **Section 5 and Appendix C, Code section**. We **omitted** methods simple to implement (like MC-Dropout) that are known to have **suboptimal performance** or that **assume knowledge of the OOD data** at training time. We would gently ask the reviewer to pick any of the above OOD papers (and these other papers [8, 11,12,13,14,15, 16] ) to realise the choice and amounts of baselines is either comparable or **superior** to most of the papers cited. Differently from most of these papers, we also compare using multiple uncertainty estimation tasks using several datasets and architectures. We trained each of the baselines from scratch (where possible) and cross-validated all the hyperparameters to allow them to produce the **best performance possible**.",

Following, we also create two additional strong and simple baselines where a ResNet is enforced to be bi-Lipschitz using Spectral Normalization (SN) and Stable Rank Normalization (SRN).

Further details provided in Appendix C.****Code For the SNGP method we use the official code-base with the suggested hyperparameters and training procedures. The code diverges slightly from the procedure described in their paper, hence the slight differences in the performance. The only modification we performed to the official code-base was to make the inference procedure consistent with the one described in the paper: indeed, in their code they implement a mean-field approximation to estimate the predictive distribution (Lu et al., 2020), while in their paper they use Monte Carlo Integration with a number of samples equal to the number of members in the ensembles they use as a baseline, which provides better calibration. The rationale is that we could not find an obvious way to tune the mean-field approximation hyperparameters to improve at the same time both the calibration and OOD detection performance (indeed, the mean-field approximation imposes a trade-off between calibration and OOD detection performance). Additionally, since the standard KFAC-LLLA uses the same Monte Carlo Integration procedure,we opted for the latter for a fair comparison. For the KFAC-LLLA we leverage the official repository7 (Hobbhahn et al., 2021) and the Backpack library (Dangel et al., 2020) for the computation of the Kronecker-Factored Hessian. For the SNGP ResNet50 experiments, we tried running the official implementation. The official implementation for ResNet50 is specifically fine-tuned for ImageNet, and has not been used for experiments on CIFAR. We could not make SNGP converge to SOTA accuracy values both on CIFAR-10 and CIFAR-100. All the other methods were implemented by us in PyTorch and the training, cross-validation and evaluation code will be made publicly available upon acceptance of the paper.",

        "question": "Which kind of training does the Variational Bayesian inference-based acoustic unit discovery framework allow?",
        "answer": "Allows parallelized large-scale training.",
        "evidence": "Topic identification (topic ID) on speech aims to identify the topic(s) for given speech recordings, referred to as spoken documents, where the topics are a predefined set of classes or labels. This task is typically formulated as a three-step process. First, speech is tokenized into words or phones by automatic speech recognition (ASR) systems BIBREF0 , or by limited-vocabulary keyword spotting BIBREF1 . Second, standard text-based processing techniques are applied to the resulting tokenizations, and produce a vector representation for each spoken document, typically a bag-of-words multinomial representation, or a more compact vector given by probabilistic topic models BIBREF2 , BIBREF3 . Finally, topic ID is performed on the spoken document representations by supervised training of classifiers, such as Bayesian classifiers and support vector machines (SVMs).\nHowever, in the first step, training the ASR system required for tokenization itself requires transcribed speech and pronunciations. In this paper, we focus on a difficult and realistic scenario where the speech corpus of a test language is annotated only with a minimal number of topic labels, i.e., no manual transcriptions or dictionaries for building an ASR system are available. We aim to exploit approaches that enable topic ID on speech without any knowledge of that language other than the topic annotations.\nIn this scenario, while previous work demonstrates that the cross-lingual phoneme recognizers can produce reasonable speech tokenizations BIBREF4 , BIBREF5 , the performance is highly dependent on the language and environmental condition (channel, noise, etc.) mismatch between the training and test data. Therefore, we focus on unsupervised approaches that operate directly on the speech of interest. Raw acoustic feature-based unsupervised term discovery (UTD) is one such approach that aims to identify and cluster repeating word-like units across speech based around segmental dynamic time warping (DTW) BIBREF6 , BIBREF7 . BIBREF8 shows that using the word-like units from UTD for spoken document classification can work well; however, the results in BIBREF8 are limited since the acoustic features on which UTD is performed are produced by acoustic models trained from the transcribed speech of its evaluation corpus. In this paper, we investigate UTD-based topic ID performance when UTD operates on language-independent speech representations extracted from multilingual bottleneck networks trained on languages other than the test language BIBREF9 . Another alternative to producing speech tokenizations without language dependency is the model-based approach, i.e., unsupervised learning of hidden Markov model (HMM) based phoneme-like units from untranscribed speech. We exploit the Variational Bayesian inference based acoustic unit discovery (AUD) framework in BIBREF10 that allows parallelized large-scale training. In topic ID tasks, such AUD-based systems have been shown to outperform other systems based on cross-lingual phoneme recognizers BIBREF5 , and this paper aims to further investigate how the performance compares among UTD, AUD and ASR based systems.\nMoreover, after the speech is tokenized, these works BIBREF0 , BIBREF1 , BIBREF4 , BIBREF5 , BIBREF8 , BIBREF9 are limited to using bag-of-words features as spoken document representations. While UTD only identifies relatively long (0.5 – 1 sec) repeated terms, AUD/ASR enables full-coverage segmentation of continuous speech into a sequence of units/words, and such a resulting temporal sequence enables another feature learning architecture based on convolutional neural networks (CNNs) BIBREF11 ; instead of treating the sequential tokens as a bag of acoustic units or words, the whole token sequence is encoded as concatenated continuous vectors, and followed by convolution and temporal pooling operations that capture the local and global dependencies. Such continuous space feature extraction frameworks have been used in various language processing tasks like spoken language understanding BIBREF12 , BIBREF13 and text classification BIBREF14 , BIBREF15 . However, three questions are worth investigating in our AUD-based setting: (i) if such a CNN-based framework can perform as well on noisy automatically discovered phoneme-like units as on orthographic words/characters, (ii) if pre-trained vectors of phoneme-like units from word2vec BIBREF16 provide superior performance to random initialization as evidenced by the word-based tasks, and (iii) if CNNs are still competitive in low-resource settings of hundreds to two-thousand training exemplars, rather than the large/medium sized datasets as in previous work BIBREF14 , BIBREF15 .\nFinally, incorporating the different tokenization and feature representation approaches noted above, we perform comprehensive topic ID evaluations on both single-label and multi-label spoken document classification tasks.\n\nWe exploit the Variational Bayesian inference based acoustic unit discovery (AUD) framework in that allows parallelized large-scale training.",

        "question": "Please list the key points about Bangladesh economy from the paragraph below:",
        "evidence": "Bangladesh is the second largest economy in South Asia after India. The country has outpaced India (of which it was a part until 1947) and Pakistan (of which it was a part until 1971) in terms of per capita income. According to the World Bank, \"When the newly independent country of Bangladesh was born on December 16, 1971, it was the second poorest country in the world—making the country's transformation over the next 50 years one of the great development stories. Since then, poverty has been cut in half at record speed. Enrolment in primary school is now nearly universal. Hundreds of thousands of women have entered the workforce. Steady progress has been made on maternal and child health. And the country is better buttressed against the destructive forces posed by climate change and natural disasters. Bangladesh's success comprises many moving parts—from investing in human capital to establishing macroeconomic stability. Building on this success, the country is now setting the stage for further economic growth and job creation by ramping up investments in energy, inland connectivity, urban projects, and transport infrastructure, as well as prioritizing climate change adaptation and disaster preparedness on its path toward sustainable growth\".\n\nAfter the partition of India, the region underwent a change in economic geography. In East Pakistan, free market principles were generally accepted. The government promoted industrialization to produce consumer goods as quickly as possible in order to avoid dependence on imports. Certain sectors, like public utilities, fell under state ownership. Demand for jute during the Korean War led to the creation of the Adamjee Jute Mills, which replaced jute mills in Dundee and Calcutta as the largest jute mill in the world. However, by the 1960s, East Pakistan's share of exports fell from 70% to 50% as West Pakistan received the major portion of investments. Economic grievances played a key role in the pro-independence aspirations of East Pakistanis. During the initial five years of independence (1971-1975), newly created Bangladesh followed a socialist economy. In the late 1970s, socialist policies were largely reversed, industrial plants were returned to private owners, and private industry was increasingly promoted. The government set up export processing zones to stimulate the export economy. Between 1991 and 1993, finance minister Saifur Rahman launched further reforms with support from the IMF which liberalized the economy and boosted industrial growth, services, and exports. By the late 1990s and early 2000s, the reform momentum lost steam due to chronic political instability, but the economy continued to grow.\n\nIn 2022, Bangladesh had the second largest foreign-exchange reserves in South Asia. The reserves have boosted the government's spending capacity in spite of tax revenues forming only 7.7% of government revenue. A big chunk of investments have gone into the power sector. In 2009, Bangladesh was experiencing daily blackouts several times a day. In 2022, the country achieved 100% electrification. One of the major anti-poverty schemes of the Bangladeshi government is the Ashrayan Project which aims to eradicate homelessness by providing free housing. The poverty rate has gone down from 80% in 1971, to 44.2% in 1991, to 12.9% in 2021. The literacy rate stood at 74.66% in 2022. Bangladesh has a labor force of roughly 70 million, which is the world's seventh-largest; with an unemployment rate of 5.2% as of 2021. The government is setting up 100 special economic zones to attract foreign direct investment (FDI) and generate 10 million jobs. The Bangladesh Investment Development Authority (BIDA) and the Bangladesh Economic Zones Authority (BEZA) have been established to help investors in setting up factories; and to complement the longstanding Bangladesh Export Processing Zone Authority (BEPZA). The Bangladeshi taka is the national currency. The service sector accounts for about 51.3% of total GDP and employs 39% of the workforce. The industrial sector accounts for 35.1% of GDP and employs 20.4% of the workforce. The agriculture sector makes up 13.6% of the economy but is the biggest employment sector, with 40.6% of the workforce. In agriculture, the country is a major producer of rice, fish, tea, fruits, vegetables, flowers, and jute. Lobsters and shrimps are some of Bangladesh's well known exports.",

His best-known titles are the 1848 pamphlet The Communist Manifesto and the four-volume Das Kapital (1867–1883). Marx's political and philosophical thought had enormous influence on subsequent intellectual, economic, and political history. His name has been used as an adjective, a noun, and a school of social theory.\n\nBorn in Trier, Germany, Marx studied law and philosophy at the universities of Bonn and Berlin. He married German theatre critic and political activist Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German philosopher Friedrich Engels and publish his writings, researching in the British Museum Reading Room.\n\nMarx's critical theories about society, economics, and politics, collectively understood as Marxism, hold that human societies develop through class conflict. In the capitalist mode of production, this manifests itself in the conflict between the ruling classes (known as the bourgeoisie) that control the means of production and the working classes (known as the proletariat) that enable these means by selling their labour-power in return for wages. Employing a critical approach known as historical materialism, Marx predicted that capitalism produced internal tensions like previous socioeconomic systems and that these tensions would lead to its self-destruction and replacement by a new system known as the socialist mode of production. For Marx, class antagonisms under capitalism—owing in part to its instability and crisis-prone nature—would eventuate the working class's development of class consciousness, leading to their conquest of political power and eventually the establishment of a classless, communist society constituted by a free association of producers. Marx actively pressed for its implementation, arguing that the working class should carry out organised proletarian revolutionary action to topple capitalism and bring about socio-economic emancipation.\n\nMarx has been described as one of the most influential figures in human history, and his work has been both lauded and criticised. His work in economics laid the basis for some current theories about labour and its relation to capital. Many intellectuals, labour unions, artists, and political parties worldwide have been influenced by Marx's work, often modifying or adapting his ideas. Marx is typically cited as one of the principal architects of modern social science.",

        "evidence": "Keyphrases are single or multi-word lexical units that best summarise a document BIBREF0. As such, they are of great importance for indexing, categorising and browsing digital libraries BIBREF1. Yet, very few documents have keyphrases assigned, thus raising the need for automatic keyphrase generation systems. This task falls under the task of automatic keyphrase extraction which can also be the subtask of finding keyphrases that only appear in the input document. Generating keyphrases can be seen as a particular instantiation of text summarization, where the goal is not to produce a well-formed piece of text, but a coherent set of phrases that convey the most salient information. Those phrases may or may not appear in the document, the latter requiring some form of abstraction to be generated. State-of-the-art systems for this task rely on recurrent neural networks BIBREF2, BIBREF3, BIBREF4, and hence require large amounts of annotated training data to achieve good performance. As gold annotated data is expensive and difficult to obtain BIBREF5, previous works focused on readily available scientific abstracts and used author-assigned keyphrases as a proxy for expert annotations. However, this poses two major issues: 1) neural models for keyphrase generation do not generalize well across domains, thus limiting their use in practice; 2) author-assigned keyphrases exhibit strong consistency issues that negatively impacts the model's performance. There is therefore a great need for annotated data from different sources, that is both sufficiently large to support the training of neural-based models and that comprises gold-standard labels provided by experts. In this study, we address this need by providing KPTimes, a dataset made of 279 923 news articles that comes with editor-assigned keyphrases.\nOnline news are particularly relevant to keyphrase generation since they are a natural fit for faceted navigation BIBREF6 or topic detection and tracking BIBREF7. Also, and not less importantly, they are available in large quantities and are sometimes accompanied by metadata containing human-assigned keyphrases initially intended for search engines. Here, we divert these annotations from their primary purpose, and use them as gold-standard labels to automatically build our dataset. More precisely, we collect data by crawling selected news websites and use heuristics to draw texts paired with gold keyphrases. We then explore the resulting dataset to better understand how editors tag documents, and how these expert annotations differ from author-assigned keyphrases found in scholarly documents. Finally, we analyse the performance of state-of-the-art keyphrase generation models and investigate their transferability to the news domain and the impact of domain shift.\nFinally, we analyse the performance of state-of-the-art keyphrase generation models and investigate their transferability to the news domain and the impact of domain shift.",

Conventional approaches still rely on comprehensive hand-tuning templates and rules requiring expert knowledge of linguistic representation, including rule-based BIBREF0 , corpus-based n-gram models BIBREF1 , and a trainable generator BIBREF2 .\nRecently, Recurrent Neural Networks (RNNs) based approaches have shown promising performance in tackling the NLG problems. The RNN-based models have been applied for NLG as a joint training model BIBREF3 , BIBREF4 and an end-to-end training model BIBREF5 . A recurring problem in such systems is requiring annotated datasets for particular dialogue acts (DAs). To ensure that the generated utterance representing the intended meaning of the given DA, the previous RNN-based models were further conditioned on a 1-hot vector representation of the DA. BIBREF3 introduced a heuristic gate to ensure that all the slot-value pair was accurately captured during generation. BIBREF4 subsequently proposed a Semantically Conditioned Long Short-term Memory generator (SC-LSTM) which jointly learned the DA gating signal and language model.\nMore recently, Encoder-Decoder networks BIBREF6 , BIBREF7 , especially the attentional based models BIBREF8 , BIBREF9 have been explored to solve the NLG tasks. The Attentional RNN Encoder-Decoder BIBREF10 (ARED) based approaches have also shown improved performance on a variety of tasks, e.g., image captioning BIBREF11 , BIBREF12 , text summarization BIBREF13 , BIBREF14 .\nWhile the RNN-based generators with DA gating-vector can prevent the undesirable semantic repetitions, the ARED-based generators show signs of better adapting to a new domain. However, none of the models show significant advantage from out-of-domain data. To better analyze model generalization to an unseen, new domain as well as model leveraging the out-of-domain sources, we propose a new architecture which is an extension of the ARED model. In order to better select, aggregate and control the semantic information, a Refinement Adjustment LSTM-based component (RALSTM) is introduced to the decoder side. The proposed model can learn from unaligned data by jointly training the sentence planning and surface realization to produce natural language sentences. We conducted experiments on four different NLG domains and found that the proposed methods significantly outperformed the state-of-the-art methods regarding BLEU BIBREF15 and slot error rate ERR scores BIBREF4 . The results also showed that our generators could scale to new domains by leveraging the out-of-domain data. To sum up, we make three key contributions in this paper:\nWe review related works in Section \"Related Work\" . Following a detail of proposed model in Section \"Recurrent Neural Language Generator\" , Section \"Experiments\" describes datasets, experimental setups, and evaluation metrics. The resulting analysis is presented in Section \"Results and Analysis\" . We conclude with a brief summary and future work in Section \"Conclusion and Future Work\" .\nWhile the RNN-based generators with DA gating-vector can prevent the undesirable seman- tic repetitions, the ARED-based generators show signs of better adapting to a new domain.",

        "evidence": "According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), symptoms of DID include \"the presence of two or more distinct personality states\" accompanied by the inability to recall personal information beyond what is expected through normal memory issues. Other DSM-5 symptoms include a loss of identity as related to individual distinct personality states, loss of one's subjective experience of the passage of time, and degradation of a sense of self and consciousness. In each individual, the clinical presentation varies and the level of functioning can change from severe impairment to minimal impairment. The symptoms of dissociative amnesia are subsumed under a DID diagnosis, and thus should not be diagnosed separately if DID criteria are met. Individuals with DID may experience distress from both the symptoms of DID (intrusive thoughts or emotions) and the consequences of the accompanying symptoms (dissociation rendering them unable to remember specific information). The majority of patients with DID report childhood sexual or physical abuse. Amnesia between identities may be asymmetrical; identities may or may not be aware of what is known by another. Individuals with DID may be reluctant to discuss symptoms due to associations with abuse, shame, and fear. DID patients may also frequently and intensely experience time disturbances. Around half of people with DID have fewer than 10 identities and most have fewer than 100; although as many as 4,500 have been reported. The average number of identities has increased over the past few decades, from two or three to now an average of approximately 16. However, it is unclear whether this is due to an actual increase in identities, or simply that the psychiatric community has become more accepting of a high number of compartmentalized memory components.",

        "question": "Please give a brief history of AI.",
        "evidence": "The Dartmouth Workshop of 1956 was organized by Marvin Minsky, John McCarthy and two senior scientists: Claude Shannon and Nathan Rochester of IBM. The proposal for the conference included this assertion: \"every aspect of learning or any other feature of intelligence can be so precisely described that a machine can be made to simulate it\".The participants included Ray Solomonoff, Oliver Selfridge, Trenchard More, Arthur Samuel, Allen Newell and Herbert A. Simon, all of whom would create important programs during the first decades of AI research. At the workshop Newell and Simon debuted the \"Logic Theorist\" and McCarthy persuaded the attendees to accept \"Artificial Intelligence\" as the name of the field. The 1956 Dartmouth workshop was the moment that AI gained its name, its mission, its first success and its major players, and is widely considered the birth of AI. The term \"Artificial Intelligence\" was chosen by McCarthy to avoid associations with cybernetics and connections with the influential cyberneticist Norbert Wiener.\n\nThe programs developed in the years after the Dartmouth Workshop were, to most people, simply \"astonishing\" computers were solving algebra word problems, proving theorems in geometry and learning to speak English. Few at the time would have believed that such \"intelligent\" behavior by machines was possible at all. Researchers expressed an intense optimism in private and in print, predicting that a fully intelligent machine would be built in less than 20 years. Government agencies like DARPA poured money into the new field.\n\nIn the 1970s, AI was subject to critiques and financial setbacks. AI researchers had failed to appreciate the difficulty of the problems they faced. Their tremendous optimism had raised expectations impossibly high, and when the promised results failed to materialize, funding for AI disappeared. At the same time, the field of connectionism (or neural nets) was shut down almost completely for 10 years by Marvin Minsky's devastating criticism of perceptrons. Despite the difficulties with public perception of AI in the late 70s, new ideas were explored in logic programming, commonsense reasoning and many other areas.\n\nIn the 1980s a form of AI program called \"expert systems\" was adopted by corporations around the world and knowledge became the focus of mainstream AI research. In those same years, the Japanese government aggressively funded AI with its fifth generation computer project. Another encouraging event in the early 1980s was the revival of connectionism in the work of John Hopfield and David Rumelhart. Once again, AI had achieved success.\n\nThe business community's fascination with AI rose and fell in the 1980s in the classic pattern of an economic bubble. The collapse was due to the failure of commercial vendors to develop a wide variety of workable solutions. As dozens of companies failed, the perception was that the technology was not viable. However, the field continued to make advances despite the criticism. Numerous researchers, including robotics developers Rodney Brooks and Hans Moravec, argued for an entirely new approach to artificial intelligence.\n\nThe field of AI, now more than a half a century old, finally achieved some of its oldest goals. It began to be used successfully throughout the technology industry, although somewhat behind the scenes. Some of the success was due to increasing computer power and some was achieved by focusing on specific isolated problems and pursuing them with the highest standards of scientific accountability. Still, the reputation of AI, in the business world at least, was less than pristine. Inside the field there was little agreement on the reasons for AI's failure to fulfill the dream of human level intelligence that had captured the imagination of the world in the 1960s. Together, all these factors helped to fragment AI into competing subfields focused on particular problems or approaches, sometimes even under new names that disguised the tarnished pedigree of \"artificial intelligence\". AI was both more cautious and more successful than it had ever been.\n\nIn the first decades of the 21st century, access to large amounts of data (known as \"big data\"), cheaper and faster computers and advanced machine learning techniques were successfully applied to many problems throughout the economy. In fact, McKinsey Global Institute estimated in their famous paper \"Big data: The next frontier for innovation, competition, and productivity\" that \"by 2009, nearly all sectors in the US economy had at least an average of 200 terabytes of stored data\".\n\nBy 2016, the market for AI-related products, hardware, and software reached more than 8 billion dollars, and the New York Times reported that interest in AI had reached a \"frenzy\". The applications of big data began to reach into other fields as well, such as training models in ecology and for various applications in economics. Advances in deep learning (particularly deep convolutional neural networks and recurrent neural networks) drove progress and research in image and video processing, text analysis, and even speech recognition.",

During development language models trained on the tweet data performed better. However during the evaluation and post-evaluation stage, language models trained on the news data were significantly more effective. We also observed that bigram language models performed slightly better than trigram models on the evaluation data. This suggests that going forward we should also consider both the use of unigram and character–level language models.\nThese results suggest that there are only slight differences between bigram and trigram models, and that the type and quantity of corpora used to train the models is what really determines the results.\nThe task description paper BIBREF6 reported system by system results for each hashtag. We were surprised to find that our performance on the hashtag file #BreakUpIn5Words in the evaluation stage was significantly better than any other system on both Subtask A (with accuracy of 0.913) and Subtask B (with distance score of 0.636). While we still do not fully understand the cause of these results, there is clearly something about the language used in this hashtag that is distinct from the other hashtags, and is somehow better represented or captured by a language model. Reaching a better understanding of this result is a high priority for future work.\nThe tweet data was significantly smaller than the news data, and so certainly we believe that this was a factor in the performance during the evaluation stage, where the models built from the news data were significantly more effective. Going forward we plan to collect more tweet data, particularly those that participate in #HashtagWars. We also intend to do some experiments where we cut the amount of news data and then build models to see how those compare.\nWhile our language models performed well, there is some evidence that neural network models can outperform standard back-off N-gram models BIBREF12 .

Therefore, we think that there is a room for improvements which can be achieved by interactively asking for additional information in conversational dialogs with users. This extra information can be used for improving policies of dialog systems. We call this approach the interactive learning from dialogs.\nWe can improve dialog systems in several aspects through interactive learning in a direct interaction with users. First, the most straightforward way obviously is getting the correct answer for questions that the system does not know. We can try to ask users for answers on questions that the system encountered in a conversation with a different user and did not understand it. Second, the system can ask the user for a broader explanation of a question. This explanation could help the system to understand the question and provide the correct answer. In addition, the system can learn correct policy for the question which allows providing answers without asking any extra information for similar questions next time. We hypothesize that users are willing to give such explanations because it could help them to find answers for their own questions. The last source of information that we consider for interactive learning is rephrasing, which could help when the system does know the concept but does not know the correct wording.

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.",

        "answer": "They extract embeddings for questions, predicates and entities purely from their character-level  representations.",
        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nSecond, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level  representations.",

        "evidence": "\nAntisocial behavior. Antisocial behavior online comes in many forms, including harassment BIBREF30, cyberbullying BIBREF31, and general aggression BIBREF32. Prior work has sought to understand different aspects of such behavior, including its effect on the communities where it happens BIBREF33, BIBREF34, the actors involved BIBREF35, BIBREF36, BIBREF37, BIBREF38 and connections to the outside world BIBREF39.\nPost-hoc classification of conversations. There is a rich body of prior work on classifying the outcome of a conversation after it has concluded, or classifying conversational events after they happened. Many examples exist, but some more closely related to our present work include identifying the winner of a debate BIBREF40, BIBREF41, BIBREF42, identifying successful negotiations BIBREF21, BIBREF43, as well as detecting whether deception BIBREF44, BIBREF45, BIBREF46 or disagreement BIBREF47, BIBREF48, BIBREF49, BIBREF50, BIBREF51 has occurred.\nOur goal is different because we wish to forecast conversational events before they happen and while the conversation is still ongoing (potentially allowing for interventions). Note that some post-hoc tasks can also be re-framed as forecasting tasks (assuming the existence of necessary labels); for instance, predicting whether an ongoing conversation will eventually spark disagreement BIBREF18, rather than detecting already-existing disagreement.\nConversational forecasting. As described in Section SECREF1, prior work on forecasting conversational outcomes and events has largely relied on hand-crafted features to capture aspects of conversational dynamics. Example feature sets include statistical measures based on similarity between utterances BIBREF16, sentiment imbalance BIBREF20, flow of ideas BIBREF20, increase in hostility BIBREF8, reply rate BIBREF11 and graph representations of conversations BIBREF52, BIBREF17. By contrast, we aim to automatically learn neural representations of conversational dynamics through pre-training.\nSuch hand-crafted features are typically extracted from fixed-length windows of the conversation, leaving unaddressed the problem of unknown horizon. While some work has trained multiple models for different window-lengths BIBREF8, BIBREF18, they consider these models to be independent and, as such, do not address the issue of aggregating them into a single forecast (i.e., deciding at what point to make a prediction). We implement a simple sliding windows solution as a baseline (Section SECREF5).\nPre-training for NLP. The use of pre-training for natural language tasks has been growing in popularity after recent breakthroughs demonstrating improved performance on a wide array of benchmark tasks BIBREF53, BIBREF54. Existing work has generally used a language modeling objective as the pre-training objective; examples include next-word prediction BIBREF55, sentence autoencoding, BIBREF56, and machine translation BIBREF57. BERT BIBREF58 introduces a variation on this in which the goal is to predict the next sentence in a document given the current sentence. Our pre-training objective is similar in spirit, but operates at a conversation level, rather than a document level. We hence view our objective as conversational modeling rather than (only) language modeling. Furthermore, while BERT's sentence prediction objective is framed as a multiple-choice task, our objective is framed as a generative task.\n\nPre-training for NLP.

        "question": "Why do they propose an evaluation metric based on relevance analysis of summaries?",
        "answer": "To overcome the limitation of high lexical dependence in ROUGE.",
        "evidence": "Automatic text summarization has been an active research area in natural language processing for several decades. To compare and evaluate the performance of different summarization systems, the most intuitive approach is assessing the quality of the summaries by human evaluators. However, manual evaluation is expensive and the obtained results are subjective and difficult to reproduce BIBREF0 . To address these problems, automatic evaluation measures for summarization have been proposed. Rouge BIBREF1 is one of the first and most widely used metrics in summarization evaluation. It facilitates evaluation of system generated summaries by comparing them to a set of human written gold-standard summaries. It is inspired by the success of a similar metric Bleu BIBREF2 which is being used in Machine Translation (MT) evaluation. The main success of Rouge is due to its high correlation with human assessment scores on standard benchmarks BIBREF1 . Rouge has been used as one of the main evaluation metrics in later summarization benchmarks such as TAC[1] BIBREF3 .\n[1]Text Analysis Conference (TAC) is a series of workshops for evaluating research in Natural Language Processing\nSince the establishment of Rouge, almost all research in text summarization have used this metric as the main means for evaluating the quality of the proposed approaches. The public availability of Rouge as a toolkit for summarization evaluation has contributed to its wide usage. While Rouge has originally shown good correlations with human assessments, the study of its effectiveness was only limited to a few benchmarks on news summarization data (DUC[2] 2001-2003 benchmarks). Since 2003, summarization has grown to much further domains and genres such as scientific documents, social media and question answering. While there is not enough compelling evidence about the effectiveness of Rouge on these other summarization tasks, published research is almost always evaluated by Rouge. In addition, Rouge has a large number of possible variants and the published research often (arbitrarily) reports only a few of these variants.\n[2]Document Understanding Conference (DUC) was one of NIST workshops that provided infrastructure for evaluation of text summarization methodologies (http://duc.nist.gov/).\nBy definition, Rouge solely relies on lexical overlaps (such as n-gram and sequence overlaps) between the system generated and human written gold-standard summaries. Higher lexical overlaps between the two show that the system generated summary is of higher quality. Therefore, in cases of terminology nuances and paraphrasing, Rouge is not accurate in estimating the quality of the summary.\nWe study the effectiveness of Rouge for evaluating scientific summarization. Scientific summarization targets much more technical and focused domains in which the goal is providing summaries for scientific articles. Scientific articles are much different than news articles in elements such as length, complexity and structure. Thus, effective summarization approaches usually have much higher compression rate, terminology variations and paraphrasing BIBREF4 .\nScientific summarization has attracted more attention recently (examples include works by abu2011coherent, qazvinian2013generating, and cohan2015scientific). Thus, it is important to study the validity of existing methodologies applied to the evaluation of news article summarization for this task. In particular, we raise the important question of how effective is Rouge, as an evaluation metric for scientific summarization? We answer this question by comparing Rouge scores with semi-manual evaluation score (Pyramid) in TAC 2014 scientific summarization dataset[1]. Results reveal that, contrary to the common belief, correlations between Rouge and the Pyramid scores are weak, which challenges its effectiveness for scientific summarization. Furthermore, we show a large variance of correlations between different Rouge variants and the manual evaluations which further makes the reliability of Rouge for evaluating scientific summaries less clear. We then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in Rouge. We call our metric Sera (Summarization Evaluation by Relevance Analysis). Results show that the proposed metric achieves higher and more consistent correlations with semi-manual assessment scores.\n[1]http://www.nist.gov/tac/2014/BiomedSumm/\nOur contributions are as follows:\n[2]The annotations can be accessed via the following repository: https://github.com/acohan/TAC-pyramid-Annotations/\nWe then propose an evaluation metric based on relevance analysis of summaries which aims to overcome the limitation of high lexical dependence in ROUGE.",

The hamburger remains as one of the cheapest sources of beef in America.\n\nAdding cheese to hamburgers became popular in 1920. There are several competing claims as to who created the first cheeseburger. Lionel Sternberger is reputed to have introduced the cheeseburger in 1924 at the age of 16. He was working as a fry cook at his father's Pasadena, California sandwich shop, \"The Rite Spot\", and \"experimentally dropped a slab of American cheese on a sizzling hamburger.\" An early example of the cheeseburger appearing on a menu is a 1928 menu for the Los Angeles restaurant O'Dell's which listed a cheeseburger smothered with chili for 25 cents.\n\nOther restaurants also claim to have invented the cheeseburger. For example, Kaelin's Restaurant in Louisville, Kentucky, said it invented the cheeseburger in 1934. One year later, a trademark for the name \"cheeseburger\" was awarded to Louis Ballast of the Humpty Dumpty Drive-In in Denver, Colorado. According to Steak 'n Shake archives, the restaurant's founder, Gus Belt, applied for a trademark on the word in the 1930s.\n\nAn A&W Restaurants franchise in Lansing, Michigan is credited with inventing the bacon cheeseburger in 1963, putting it on the menu after repeated requests from the same customer.\n\nThe steamed cheeseburger, a variation almost exclusively served in central Connecticut, is believed to have been invented at a restaurant called Jack's Lunch in Middletown, Connecticut, in the 1930s.\n\nThe largest cheeseburger ever made weighed 2,014 pounds (914 kg). It is said to have included \"60 pounds (27 kg) of bacon, 50 pounds (23 kg) of lettuce, 50 pounds (23 kg) of sliced onions, 40 pounds (18 kg) of pickles, and 40 pounds (18 kg) of cheese.\" This record was set in 2012 by Minnesota's Black Bear Casino, smashing the previous record of 881 pounds (400 kg).\n\nIn the United States, National Cheeseburger Day is celebrated annually on September 18.",

The goal of our crowdsourcing scheme is to obtain a score for each proposition indicating its importance in a document cluster, such that a ranking according to the score would reveal what is most important and should be included in a summary. In contrast to other work, we do not show the documents to the workers at all, but provide only a description of the document cluster's topic along with the propositions. This ensures that tasks are small, simple and can be done quickly (see Figure FIGREF4 ).\nIn preliminary tests, we found that this design, despite the minimal context, works reasonably on our focused clusters on common educational topics. For instance, consider Figure FIGREF4 : One can easily say that P1 is more important than P2 without reading the documents.\nWe distinguish two task variants:\nInstead of enforcing binary importance decisions, we use a 5-point Likert-scale to allow more fine-grained annotations. The obtained labels are translated into scores (5..1) and the average of all scores for a proposition is used as an estimate for its importance. This follows the idea that while single workers might find the task subjective, the consensus of multiple workers, represented in the average score, tends to be less subjective due to the “wisdom of the crowd”. We randomly group five propositions into a task.\nAs an alternative, we use a second task design based on pairwise comparisons. Comparisons are known to be easier to make and more consistent BIBREF32 , but also more expensive, as the number of pairs grows quadratically with the number of objects. To reduce the cost, we group five propositions into a task and ask workers to order them by importance per drag-and-drop.

        "answer": "The memory-based reading comprehension task that humans perform at an early age.",
        "evidence": "Every day textual information is being added/updated on Wikipedia, as well as other social media platforms like Facebook, Twitter, etc. These platforms receive a huge amount of unverified textual data from all its users such as News Channels, Bloggers, Journalists, Field-Experts which ought to be verified before other users start consuming it. This information boom has increased the demand of information verification also known as Fact Checking. Apart from the encyclopedia and other platforms, domains like scientific publications and e-commerce also require information verification for reliability purposes. Generally, Wikipedia authors, bloggers, journalists and scientists provide references to support their claims. Providing referenced text against the claims makes the fact checking task a little easier as the verification system no longer needs to search for the relevant documents.\nWikipedia manages to verify all this new information with a number of human reviewers. Manual review processes introduce delays in publishing and is not a well scalable approach. To address this issue, researchers have launched relevant challenges, such as the Fake News Challenge (BIBREF0), Fact Extraction and VERification (FEVER) (BIBREF1) challenge along with the datasets. Moreover, Thorne and Vlachos (BIBREF2) released a survey on the current models for automated fact-checking. FEVER is the largest dataset and contains around 185k claims from the corpus of 5.4M Wikipedia articles. The claims are labeled as “SUPPORTS”, “REFUTES”, or “NOT ENOUGH INFO”, based on the evidence set.\nIn this paper, we propose an unsupervised question-answering based approach for solving the fact-checking problem. This approach is inspired from the memory-based reading comprehension task that humans perform at an early age. As we know that kids in schools, first read and learn the syllabus content so that they can answer the questions in the exam. Similarly, our model learns a language model and linguistics features in unsupervised fashion from the provided Wikipedia pages.\nTo transform the FEVER dataset into the above-mentioned task, we first generate the questions from the claims. In literature, there are majorly two types of Question Generation systems: Rule-based and Neural Question Generation (NQG) model based. Ali et al. (BIBREF3) proposed a rule-based pipeline to automate the question generation using POS (Part-of-speech) tagging and Named Entity Recognition (NER) tagging from the sentences. Recently, many NQG models have been introduced to generate questions in natural language. Serban et al. (BIBREF4) achieved better performance for question generation utilizing (passage, question, answer) triplets as training data and an encoder-decoder based architecture as their learning model.\nDu et al. (BIBREF5) introduced a sequence-to-sequence model with an attention mechanism, outperforming rule-base question generation systems. Although the models proposed in (BIBREF6; BIBREF7) are effective, they require a passage to generate the plausible questions which is not readily available in the FEVER dataset. To resolve the issues and to keep the system simple but effective, we chose to generate questions similar to a Cloze-task or masked language modeling task. Such a task makes the problem more tractable as the masked entities are already known (i.e. named entities) and tight as there is only one correct answer for a given question. Later when the answers are generated, due to the question generation process, it becomes very easy to identify the correct answers.\nWe use the BERT's (Bidirectional Encoder Representations from Transformers) (BIBREF8) masked language model, that is pre-trained on Wikipedia articles for predicting the masked entities. Currently, neither the claim verification process nor the question generation process mandates explicit reasoning. For the same reason, it is difficult to put “REFUTES” or “NOT ENOUGH INFO” labels. To resolve this issue, we classify the unsupported claims as “MANUAL_REVIEW” instead of labeling them as “NOT ENOUGH INFO” or “REFUTES”.\nIn the literature, the shared task has been tackled using pipeline-based supervised models (BIBREF9; BIBREF10; BIBREF11). To our knowledge, only BIBREF10 has provided the confusion matrix for each of the labels for their supervised system. For the same reason, we are only providing the comparison of the label accuracy on the “SUPPORTS” label in the results section.\nIn this paper, we propose an unsupervised question-answering based approach for solving the fact-checking problem.

        "question": "What is the technical significance of the proposed approach?",
        "answer": "First we notice there is a misunderstanding of our approach in this comment. After reaching the minimal block or no smaller block has a better loss, we backtrack to the last level of split blocks (instead of going back to the level of initial blocks and “applying the procedure again to the second best block”) and choose the best one of the remaining blocks for further perturbation. The intuition is that we always refine perturbations in a region that is as small as possible, which accords with our goal of perturbing smaller but more important regions to generate imperceptible AEs.\nFor our search algorithm, we agree that it is simple. However, we think that a simple yet effective algorithm is always desirable, because it can be easily understood and implemented. For examples, Parsimonious attack (Moon et al., 2019) uses greedy local search; Square attack (Andriushchenko et al., 2020) adopts an even simpler random search. But these simple algorithms can achieve very strong performance, because they are particularly suited to the problems. For the present work, the proposed search algorithm is also suited to the problem of generating AEs with small perturbations, and the results have demonstrated its effectiveness. We appreciate for the suggestion that we need to justify the search algorithm. In Table 2 (page 8), Saliency significantly outperforms Parsimonious-seg and Square-seg, which indicates that our search algorithm is better than the local search algorithm in Parsimonious Attack and the random search algorithm in Square Attack. Moreover, we have added experiments to compare our search algorithm with a new baseline greedy search in salient region, which greedily perturbs blocks to maximize marginal gain. We have fine-tuned the block size of the greedy search algorithm and the comparison results are presented in Table 3 (page 9). It can be seen that our algorithm is still significantly better. The above results that our search algorithm outperforms existing search algorithms (i.e., local search and random search) and common baseline (i.e., greedy search) indicate that it is indeed effective.\nFor using saliency maps, indeed, this idea has already appeared in the field of adversarial attack. However, to the best of our knowledge, we are the first to apply it to black-box attack on image classification model. The two papers mentioned in the comment (Guo et al.,2020; Sun et al., 2021) are both for white-box attacks. Actually we have reviewed two similar works (Dong et al., 2020; Xiang et al., 2021) in the paper, which use CAM/grad-CAM to generate saliency maps and can only be applied in white-box or grey-box settings. We introduced them and analyzed their difference and infeasibility to black-box setting thoroughly (para. 3,4, page 2). Besides, we want to clarify that our main contribution is not just introducing saliency maps into black-box attacks, but how to process and utilize saliency maps in black-box setting. The combination of saliency maps and our search algorithm bring out smaller and more imperceptible perturbations, which greatly alleviates the problem of imperceptibility in black-box attacks.",
        "evidence": "Deep neural networks (DNNs) have achieved significant progress in wide applications, such as image classification, face recognition, object detection, speech recognition and machine translation. Despite their success, deep learning models have revealed vulnerability to adversarial attacks. Crafted by adding some small perturbations to benign inputs, adversarial examples (AEs) can fool DNNs into making wrong predictions, which is a critical threat especially for some security-sensitive scenarios such as autonomous driving.\nBased on the knowledge of target model, the adversarial attacks could be divided into white-box attack and black-box attack. White-box attacks have full access to the architecture and parameters of the target model, and can easily generate a successful adversarial example via back propagation. By contrast, black-box attacks can only query the target model to obtain the output prediction, which is a more realistic and challenging setting. Since many real-world online application programming interfaces (APIs) have time or monetary limit for user query, most current research efforts focus on how to design query-efficient attacks, which indeed achieve a huge improvement. For example, so far the state-of-the-art black-box attack could succeed in untargeted attack on ImageNet dataset with only tens of queries on average. However, this success has sacrificed the imperceptibility of AEs, whose global perturbations are generated with various tricks like random vertical stripes, and thus very obvious and perceptible to human eyes (see Figure (e) and (f) for examples). In effect, imperceptibility is essential for attackers. Currently online APIs usually integrate detectors into their services to detect anomalous inputs. The images with too visible perturbations are difficult to pass these detectors, not to mention human judgement.  To alleviate or even address this problem, we could utilize some priors to lead black-box attacks to search in small but efficient space, instead of global perturbations. Previous DNNs visualization work proposed a type of saliency map to indicate which features should influence the output significantly. This BP saliency map 1 is generated by calculating the derivatives of the model output with respect to input. Just as show in Figure.(a), the brighter pixels in BP saliency maps denote they have a greater impact on the model output. The classical white-box attack JSMA just constructs such an adversarial saliency map and iteratively selects pixels from this map to perturb. But due to the black-box setting, we cannot derive this saliency map directly. Nevertheless, we could find that the region of bright pixels roughly represents the position of the main object in an image, which also accords with our intuition. Inspired by this, we propose to first generate a saliency mask to extract the regions of the main object in an image via image segmentation, and then limit the perturbation search in this smaller but more important regions, as presented in Figure.\nSeveral recent studies also propose to generate similar local perturbations but applied in different attack settings with different methods. In particular, produce saliency maps with the class activation mapping (CAM), which requires the internal information of the model and needs to change the model architecture. This is infeasible in black-box scenarios. replace CAM with Grad-CAM, which does not need to change the architecture of the model. However, both CAM and Grad-CAM still rely on the knowledge of the model, but in black-box setting the internal information of the target model is inaccessible. Thus, we choose salient object segmentation, which can automatically extract salient object(s) in an image (see Figure.(b)). Compared with CAM and Grad-CAM, it doesn't need any other information except for the input image.\nOn the other hand, these studies or assume a pretrained substitute model is trained on the similar data distribution with the target model's. And for the latter, the transferability of both adversarial examples and saliency maps highly depends on the selection of the pair of substitute model(s) and target model. Hence, in this paper we focus on gradient-free black-box attacks that take no account of gradients and search for successful perturbations only according to the model output.\nWe add these segmentation priors to SOTA black-box attacks and find the imperceptibility of AEs is indeed enhanced but still limited due to \"global perturbation\" in local region (See Figure). To further improve the imperceptibility, our another novelty is that even in the salient region, \"saliency\" could still be refined. Our inspiration also comes from some DNNs visualization works. For instance, given a dog image, CAM produces a localization heatmap and shows the dog face region is most highly lighted. systematically cover up different portions of a dog image, and finds when the dog face is obscured, the activity in the feature map and classifier output changes dramatically. In further, by combining internal feature visualization with output prediction, reveal even in dog's face region, its ears and eyes seem to be more important when distinguishing dogs. Therefore, we are inspired to assume the salient region in an image is progressive with respect to its impact on model output. If we could find smaller but more salient region, the perturbation will be more efficient and meanwhile the imperceptibility of AEs could also be enhanced. Thus, we propose our Saliency Attack, a new gradient-free black-box attack via refining perturbations in the salient region according to their saliency.\nOur main contributions can be summarized as follows:\n• To our best knowledge, we are the first to use salient object segmentation to extract binary salient masks in black-box settings. Experiments show that the SOTA black-box attacks limited in such regions can achieve much better imperceptibility performance with little reduction in query efficiency and success rate.\n• We propose a new gradient-free black-box attack via refining in salient regions. Compared with the search methods used in other gradient-free attacks, our method is able to generate smaller but effective perturbations, which is interpretable to some extent and can further improve the imperceptibility.\n• We demonstrate that the perturbations generated by our Saliency Attack is more robust against some detection-based defense like Feature Squeezing.\nOn the other hand, these studies (Dong et al., 2020; Xiang et al., 2021) are applied to transfer-based attacks (actually a grey-box setting), which first build a substitute model to approximate the target model, then use gradient-based white-box attacks to generate adversarial examples, and finally transfer them to attack the target model. For transfer-based attack, we must either train a substitute model from scratch with huge number of queries (Papernot et al., 2017) or assume a pretrained substitute model is trained on the similar data distribution with the target model’s (Liu et al., 2017). And for the latter, the transferability of both adversarial examples and saliency maps highly depends on the selection of the pair of substitute model(s) and target model. Hence, in this paper we focus on gradient-free black-box attacks (Narodytska & Kasiviswanathan, 2016; Moon et al., 2019; Andriushchenko et al., 2020) that take no account of gradients and search for successful perturbations only according to the model output. We add these segmentation priors to SOTA black-box attacks and find the imperceptibility of AEs is indeed enhanced but still limited due to ”global perturbation” in local region (See Figure 4 and 5). To further improve the imperceptibility, our another novelty is that even in the salient region, “saliency” could still be refined. Our inspiration also comes from some DNNs visualization works (Zhou et al., 2016; Zeiler & Fergus, 2014; Olah et al., 2018). For instance, given a dog image, CAM produces a localization heatmap and shows the dog face region is most highly lighted (Zhou et al., 2016). Zeiler & Fergus (2014) systematically cover up different portions of a dog image, and finds when the dog face is obscured, the activity in the feature map and classifier output changes dramatically. In further, by combining internal feature visualization with output prediction, Olah et al. (2018) reveal even in dog’s face region, its ears and eyes seem to be more important when distinguishing dogs. Therefore, we are inspired to assume the salient region in an image is progressive with respect to its impact on model output. If we could find smaller but more salient region, the perturbation will be more efficient and meanwhile the imperceptibility of AEs could also be enhanced. Thus, we propose our Saliency Attack, a new gradient-free black-box attack via refining perturbations in the salient region according to their saliency. Our main contributions can be summarized as follows: • To our best knowledge, we are the first to use salient object segmentation to extract binary salient masks in black-box settings. Experiments show that the SOTA black-box attacks limited in such regions can achieve much better imperceptibility performance with little reduction in query efficiency and success rate. • We propose a new gradient-free black-box attack via refining in salient regions. Compared with the search methods used in other gradient-free attacks, our method is able to generate smaller but effective perturbations, which is interpretable to some extent and can further improve the imperceptibility. • We demonstrate that the perturbations generated by our Saliency Attack is more robust against some detection-based defense like Feature Squeezing.",

        "question": "Where is their dataset from?",
        "answer": "An Internet Relay Chat (IRC) room.",
        "evidence": "The prevalent use of emoji—and their text-based precursors—is mostly unaddressed in current natural language processing (NLP) tasks. The support of the Unicode Standard BIBREF0 for emoji characters in 2010 ushered in a wide-spread, international adoption of these graphical elements in casual contexts. Interpreting the meaning of these characters has been challenging however, since they take on multiple semantic roles BIBREF1.\nWhether or not emoji are used depends on the context of a text or conversation, with more formal settings generally being less tolerating. So is the popular aligned corpus Europarl BIBREF2 naturally devoid of emoji. Technical limitations, like no Unicode support, also limit its use. This in turn affects commonly used corpora, tokenizers, and pre-trained networks.\nTake for example the Ubuntu Dialog Corpus by BIBREF3, a commonly used corpus for multi-turn systems. This dataset was collected from an Internet Relay Chat (IRC) room casually discussing the operating system Ubuntu. IRC nodes usually support the ASCII text encoding, so there's no support for graphical emoji. However, in the 7,189,051 utterances, there are only 9946 happy emoticons (i.e. :-) and the cruelly denosed :) version) and 2125 sad emoticons.\nWord embeddings are also handling emoji poorly: Word2vec BIBREF4 with the commonly used pre-trained Google News vectors doesn't support the graphical emoji at all and vectors for textual emoticons are inconsistent. As another example with contextualized word embeddings, there are also no emoji or textual emoticons in the vocabulary list of BERT BIBREF5 by default and support for emoji is only recently added to the tokenizer. The same is true for GPT-2 BIBREF6. As all downstream systems, ranging from multilingual résumé parsing to fallacy detection BIBREF7, rely on the completeness of these embeddings, this lack of emoji support can affect the performance of some of these systems.\nAnother challenge is that emoji usage isn't static. Think of shifting conventions, different cultures, and newly added emoji to the Unicode list. Several applications also use their own custom emoji, like chat application Slack and streaming service Twitch. This becomes an issue for methods that leverage the Unicode description BIBREF8 or that rely on manual annotations BIBREF9.\nOur contribution with this paper is two-fold: firstly, we argue that the current use—or rather non-existing use—of emoji in the tokenizing, training, and the datasets themselves is insufficient. Secondly, we attempt to quantify the significance of incorporating emoji-based features by presenting a fine-tuned model. We then compare this model to a baseline, but without special attention to emoji.\nSection SECREF2 will start with an overview of work on emoji representations, emoji-based models and analysis of emoji usage. A brief introduction in conversational systems will also be given. Section SECREF3 will then look into popular datasets with and without emoji and then introduce the dataset we used.\nOur model will then be discussed in Section SECREF4, including the tokenization in Subsection SECREF4, training setup in Subsection SECREF6 and evaluation in Subsection SECREF10. This brings us to the results of our experiment, which is discussed in Section SECREF5 and finally our conclusion and future work are presented in Section SECREF6.\nTake for example the Ubuntu Dialog Corpus  by Lowe et al. [20], a commonly used corpus for multi-turn systems. This dataset was collected from an Internet Relay Chat (IRC) room casually discussing the operating system Ubuntu.",

        "question": "Does the ZAT model outperform all existing methods?",
        "answer": "Yes.",
        "evidence": "Recently, there is a surge of excitement in adding numerous new domains to conversational agents such as Alexa, Google Assistant, Cortana and Siri to support a myriad of use cases. However, building a slot tagger, which is a key component for natural language understanding (NLU) BIBREF0 , for a new domain requires massive amounts of labeled data, hindering rapid development of new skills. To address the data-intensiveness problem, domain adaptation approaches have been successfully applied. Previous approaches are roughly categorized into two groups: data-driven approaches BIBREF1 , BIBREF2 and model-driven approaches BIBREF3 , BIBREF4 .\nIn the data-driven approach, new target models are trained by combining target domain data with relevant data from a repository of arbitrary labeled datasets using domain adaptation approaches such as feature augmentation BIBREF1 . A disadvantage of this approach is the increase in training time as the amount of reusable data grows. The reusable data might contain hundreds of thousands of samples, making iterative refinement prohibitive. In contrast, the model-driven approach utilizes “expert\" models for summarizing the data for reusable slots BIBREF3 , BIBREF4 . The outputs of the expert models are directly used when training new domains, allowing for faster training. A drawback of this approach is that it requires explicit concept alignments which itself is not a trivial task, potentially missing lots of reusable concepts. Additionally, it's not easy to generalize these models to new, unseen slots.\nIn this paper, we present a new domain adaptation technique for slot tagging inspired by recent advances in zero-shot learning. Traditionally, slot tagging is formulated as a sequence labeling task using the BIO representation (Figure 1 ). Our approach formulates this problem as detecting spans that contain values for each slot as shown in Figure 1 . For implicit transfer of reusable concepts across domains, we represent slots in a shared latent semantic space by embedding the slot description. With the shared latent space, domain adaptation can simply be done by fine-tuning a base model, which is trained on massive data, with a handful of target domain data without any explicit concept alignments. A similar idea of utilizing zero-shot learning for slot tagging has been proven to work in semi-supervised settings BIBREF5 . Our zero-shot model architecture differs from this by adding: 1) an attention layer to produce the slot-aware representations of input words, 2) a CRF layer to better satisfy global consistency constraints, 3) character-level embeddings to incorporate morphological information. Despite its simplicity, we show that our model outperforms all existing methods including the previous zero-shot learning approach in domain adaptation settings.\nWe first describe our approach called Zero-Shot Adaptive Transfer model (ZAT) in detail. We then describe the dataset we used for our experiments. Using this data, we conduct experiments comparing our ZAT model with a set of state-of-the-art models: Bag-of-Expert (BoE) models and their non-expert counterparts BIBREF4 , and the Concept Tagger model BIBREF5 , showing that our model can lead to significant F1-score improvements. This is followed by an in-depth analysis of the results. We then provide a survey of related work and concluding remarks.\nDespite its simplicity, we show that our model outperforms all existing methods including the previous zero-shot learning approach in domain adaptation settings.",

        "question": "Is it the first time attribute extraction using a combination of multiple modes of data has been considered?",
        "answer": "Yes.",
        "evidence": "Given the large collections of unstructured and semi-structured data available on the web, there is a crucial need to enable quick and efficient access to the knowledge content within them. Traditionally, the field of information extraction has focused on extracting such knowledge from unstructured text documents, such as job postings, scientific papers, news articles, and emails. However, the content on the web increasingly contains more varied types of data, including semi-structured web pages, tables that do not adhere to any schema, photographs, videos, and audio. Given a query by a user, the appropriate information may appear in any of these different modes, and thus there's a crucial need for methods to construct knowledge bases from different types of data, and more importantly, combine the evidence in order to extract the correct answer.\nMotivated by this goal, we introduce the task of multimodal attribute extraction. Provided contextual information about an entity, in the form of any of the modes described above, along with an attribute query, the goal is to extract the corresponding value for that attribute. While attribute extraction on the domain of text has been well-studied BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , to our knowledge this is the first time attribute extraction using a combination of multiple modes of data has been considered. This introduces additional challenges to the problem, since a multimodal attribute extractor needs to be able to return values provided any kind of evidence, whereas modern attribute extractors treat attribute extraction as a tagging problem and thus only work when attributes occur as a substring of text.\nIn order to support research on this task, we release the Multimodal Attribute Extraction (MAE) dataset, a large dataset containing mixed-media data for over 2.2 million commercial product items, collected from a large number of e-commerce sites using the Diffbot Product API. The collection of items is diverse and includes categories such as electronic products, jewelry, clothing, vehicles, and real estate. For each item, we provide a textual product description, collection of images, and open-schema table of attribute-value pairs (see Figure 1 for an example). The provided attribute-value pairs only provide a very weak source of supervision; where the value might appear in the context is not known, and further, it is not even guaranteed that the value can be extracted from the provided evidence. In all, there are over 4 million images and 7.6 million attribute-value pairs. By releasing such a large dataset, we hope to drive progress on this task similar to how the Penn Treebank BIBREF5 , SQuAD BIBREF6 , and Imagenet BIBREF7 have driven progress on syntactic parsing, question answering, and object recognition, respectively.\nTo asses the difficulty of the task and the dataset, we first conduct a human evaluation study using Mechanical Turk that demonstrates that all available modes of information are useful for detecting values. We also train and provide results for a variety of machine learning models on the dataset. We observe that a simple most-common value classifier, which always predicts the most-common value for a given attribute, provides a very difficult baseline for more complicated models to beat (33% accuracy). In our current experiments, we are unable to train an image-only classifier that can outperform this simple model, despite using modern neural architectures such as VGG-16 BIBREF8 and Google's Inception-v3 BIBREF9 . However, we are able to obtain significantly better performance using a text-only classifier (59% accuracy). We hope to improve and obtain more accurate models in further research.\nMotivated by this goal, we introduce the task of multimodal attribute extraction.

Generated summaries have been shown to support humans dealing with large document collections in information seeking tasks BIBREF0 , BIBREF1 , BIBREF2 . However, when exploring a set of documents manually, humans rarely write a fully-formulated summary for themselves. Instead, user studies BIBREF3 , BIBREF4 show that they note down important keywords and phrases, try to identify relationships between them and organize them accordingly. Therefore, we believe that the study of summarization with similarly structured outputs is an important extension of the traditional task.\nA representation that is more in line with observed user behavior is a concept map BIBREF5 , a labeled graph showing concepts as nodes and relationships between them as edges (Figure FIGREF2 ). Introduced in 1972 as a teaching tool BIBREF6 , concept maps have found many applications in education BIBREF7 , BIBREF8 , for writing assistance BIBREF9 or to structure information repositories BIBREF10 , BIBREF11 . For summarization, concept maps make it possible to represent a summary concisely and clearly reveal relationships. Moreover, we see a second interesting use case that goes beyond the capabilities of textual summaries: When concepts and relations are linked to corresponding locations in the documents they have been extracted from, the graph can be used to navigate in a document collection, similar to a table of contents. An implementation of this idea has been recently described by BIBREF12 .\nThe corresponding task that we propose is concept-map-based MDS, the summarization of a document cluster in the form of a concept map. In order to develop and evaluate methods for the task, gold-standard corpora are necessary, but no suitable corpus is available. The manual creation of such a dataset is very time-consuming, as the annotation includes many subtasks. In particular, an annotator would need to manually identify all concepts in the documents, while only a few of them will eventually end up in the summary.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations. Using it, we can avoid the high effort for single annotators, allowing us to scale to document clusters that are 15 times larger than in traditional summarization corpora. We created a new corpus of 30 topics, each with around 40 source documents on educational topics and a summarizing concept map that is the consensus of many crowdworkers (see Figure FIGREF3 ).\nAs a crucial step of the corpus creation, we developed a new crowdsourcing scheme called low-context importance annotation. In contrast to traditional approaches, it allows us to determine important elements in a document cluster without requiring annotators to read all documents, making it feasible to crowdsource the task and overcome quality issues observed in previous work BIBREF13 . We show that the approach creates reliable data for our focused summarization scenario and, when tested on traditional summarization corpora, creates annotations that are similar to those obtained by earlier efforts.\nTo summarize, we make the following contributions: (1) We propose a novel task, concept-map-based MDS (§ SECREF2 ), (2) present a new crowdsourcing scheme to create reference summaries (§ SECREF4 ), (3) publish a new dataset for the proposed task (§ SECREF5 ) and (4) provide an evaluation protocol and baseline (§ SECREF7 ). We make these resources publicly available under a permissive license.\nTo overcome these issues, we present a corpus creation method that effectively combines automatic preprocessing, scalable crowdsourcing and high-quality expert annotations.

They have been first introduced as TDNNs to predict phoneme classes BIBREF9 , and later to generate HMM posteriorgrams BIBREF10 . They have more recently been used in end-to-end frameworks, but only in combination with recurrent layers BIBREF6 , or n-gram language models BIBREF11 , or for phone recognition BIBREF12 , BIBREF13 . Nonetheless, convolutional architectures are prevalent when learning from the raw waveform BIBREF14 , BIBREF15 , BIBREF16 , BIBREF13 , BIBREF17 , because they naturally model the computation of standard features such as mel-filterbanks. Given the evidence that they are also suitable on long-range dependency tasks, we expect convolutional neural networks to be competitive at all levels of the speech recognition pipeline.\nIn this paper, we present a fully convolutional approach to end-to-end speech recognition.

        "evidence": "State-of-the-art automatic speech recognition (ASR) systems BIBREF0 have large model capacities and require significant quantities of training data to generalize. Labeling thousands of hours of audio, however, is expensive and time-consuming. A natural question to ask is how to achieve better generalization with fewer training examples. Active learning studies this problem by identifying and labeling only the most informative data, potentially reducing sample complexity. How much active learning can help in large-scale, end-to-end ASR systems, however, is still an open question.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores. In particular, an utterance is considered informative if the most likely prediction has small probability BIBREF1 , or if the predictions are distributed very uniformly over the labels BIBREF2 . Though confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) BIBREF3 , where the informativeness is measured by the norm of the gradient incurred by the instance. EGL has previously been justified as intuitively measuring the expected change in a model's parameters BIBREF3 .We formalize this intuition from the perspective of asymptotic variance reduction, and experimentally, we show EGL to be superior to confidence-based methods on speech recognition tasks. Additionally, we observe that the ranking of samples scored by EGL is not correlated with that of confidence scoring, suggesting EGL identifies aspects of an instance that confidence scores cannot capture.\nIn BIBREF3 , EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular. Gradient-based methods have also found applications outside active learning. For example, BIBREF4 suggests that in stochastic gradient descent, sampling training instances with probabilities proportional to their gradient lengths can speed up convergence. From the perspective of variance reduction, this importance sampling problem shares many similarities to problems found in active learning.\nEGL has previously been justified as intuitively measuring the expected change in a model’s parameters [4].",

However, the set of herbs is different from the textual answers to a question in the QA task. A difference that is most evident is that there will not be any duplication of herbs in the prescription. However, the basic seq2seq model sometimes produces the same herb tokens repeatedly when applied to the TCM prescription generation task. This phenomenon can hurt the performance of recall rate even after applying a post-process to eliminate repetitions. Because in a limited length of the prescription , the model would produce the same token over and over again, rather than real and novel ones. Furthermore, the basic seq2seq assumes a strict order between generated tokens, but in reality, we should not severely punish the model when it predicts the correct tokens in the wrong order. In this paper, we explore to automatically generate TCM prescriptions based on textual symptoms. We propose a soft seq2seq model with coverage mechanism and a novel soft loss function. The coverage mechanism is designed to make the model aware of the herbs that have already been generated while the soft loss function is to relieve the side effect of strict order assumption. In the experiment results, our proposed model beats all the baselines in professional evaluations, and we observe a large increase in both the recall rate and the F1 score compared with the basic seq2seq model.\nFurthermore, the basic seq2seq assumes a strict order between generated tokens, but in reality, we should not severely punish the model when it predicts the correct tokens in the wrong order.",

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe believe this gain in performance is achieved by the networks’ ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.",

Research by McAfee Labs discovered that \"Aurora\" was part of the file path on the attacker's machine that was included in two of the malware binaries McAfee said were associated with the attack. \"We believe the name was the internal name the attacker(s) gave to this operation,\" McAfee Chief Technology Officer George Kurtz said in a blog post.\n\nAccording to McAfee, the primary goal of the attack was to gain access to and potentially modify source code repositories at these high-tech, security, and defense contractor companies. \"[The SCMs] were wide open,\" says Alperovitch. \"No one ever thought about securing them, yet these were the crown jewels of most of these companies in many ways—much more valuable than any financial or personally identifiable data that they may have and spend so much time and effort protecting.\"\n\nHistory\n\nFlowers left outside Google China's headquarters after its announcement it might leave the country\nOn January 12, 2010, Google revealed on its blog that it had been the victim of a cyber attack. The company said the attack occurred in mid-December and originated from China. Google stated that over 20 other companies had been attacked; other sources have since cited that more than 34 organizations were targeted. As a result of the attack, Google said it was reviewing its business in China. On the same day, United States Secretary of State Hillary Clinton issued a brief statement condemning the attacks and requesting a response from China.\n\nOn January 13, 2010, the news agency All Headline News reported that the United States Congress plans to investigate Google's allegations that the Chinese government used the company's service to spy on human rights activists.\n\nIn Beijing, visitors left flowers outside of Google's office. However, these were later removed, with a Chinese security guard stating that this was an \"illegal flower tribute\". The Chinese government has yet to issue a formal response, although an anonymous official stated that China was seeking more information on Google's intentions.\n\nAttackers involved\nFurther information: Cyberwarfare by China\nTechnical evidence including IP addresses, domain names, malware signatures, and other factors, show Elderwood was behind the Operation Aurora attack. The \"Elderwood\" group was named by Symantec (after a source-code variable used by the attackers), and is referred to as the \"Beijing Group\" by Dell Secureworks. The group obtained some of Google's source code, as well as access to information about Chinese activists. Elderwood also targeted numerous other companies in the shipping, aeronautics, arms, energy, manufacturing, engineering, electronics, financial, and software sectors.\n\nThe \"APT\" designation for the Chinese threat actors responsible for attacking Google is APT17.\n\nElderwood specializes in attacking and infiltrating second-tier defense industry suppliers that make electronic or mechanical components for top defense companies. Those firms then become a cyber \"stepping stone\" to gain access to top-tier defense contractors. One attack procedure used by Elderwood is to infect legitimate websites frequented by employees of the target company – a so-called \"water hole\" attack, just as lions stake out a watering hole for their prey. Elderwood infects these less-secure sites with malware that downloads to a computer that clicks on the site. After that, the group searches inside the network to which the infected computer is connected, finding and then downloading executives' e-mails and critical documents on company plans, decisions, acquisitions, and product designs.\n\nAttack analysis\nIn its blog posting, Google stated that some of its intellectual property had been stolen. It suggested that the attackers were interested in accessing Gmail accounts of Chinese dissidents. According to the Financial Times, two accounts used by Ai Weiwei had been attacked, their contents read and copied; his bank accounts were investigated by state security agents who claimed he was under investigation for \"unspecified suspected crimes\". However, the attackers were only able to view details on two accounts and those details were limited to things such as the subject line and the accounts' creation date.\n\nSecurity experts immediately noted the sophistication of the attack. Two days after the attack became public, McAfee reported that the attackers had exploited purported zero-day vulnerabilities (unfixed and previously unknown to the target system developers) in Internet Explorer and dubbed the attack \"Operation Aurora\". A week after the report by McAfee, Microsoft issued a fix for the issue, and admitted that they had known about the security hole used since September. Additional vulnerabilities were found in Perforce, the source code revision software used by Google to manage their source code.\n\nVeriSign's iDefense Labs claimed that the attacks were perpetrated by \"agents of the Chinese state or proxies thereof\".\n\nAccording to a diplomatic cable from the U.S. Embassy in Beijing, a Chinese source reported that the Chinese Politburo directed the intrusion into Google's computer systems. The cable suggested that the attack was part of a coordinated campaign executed by \"government operatives, public security experts and Internet outlaws recruited by the Chinese government.\" The report suggested that it was part of an ongoing campaign in which attackers have \"broken into American government computers and those of Western allies, the Dalai Lama and American businesses since 2002.\" According to The Guardian's reporting on the leak, the attacks were \"orchestrated by a senior member of the Politburo who typed his own name into the global version of the search engine and found articles criticising him personally.\"\n\nOnce a victim's system was compromised, a backdoor connection that masqueraded as an SSL connection made connections to command and control servers running in Illinois, Texas, and Taiwan, including machines that were running under stolen Rackspace customer accounts. The victim's machine then began exploring the protected corporate intranet that it was a part of, searching for other vulnerable systems as well as sources of intellectual property, specifically the contents of source code repositories.\n\nThe attacks were thought to have definitively ended on Jan 4 when the command and control servers were taken down, although it is not known at this point whether or not the attackers intentionally shut them down. However, the attacks were still occurring as of February 2010.\n\nResponse and aftermath\nThe German, Australian, and French governments publicly issued warnings to users of Internet Explorer after the attack, advising them to use alternative browsers at least until a fix for the security hole was made. The German, Australian, and French governments considered all versions of Internet Explorer vulnerable or potentially vulnerable.\n\nIn an advisory on January 14, 2010, Microsoft said that attackers targeting Google and other U.S. companies used software that exploits a hole in Internet Explorer. The vulnerability affects Internet Explorer versions 6, 7, and 8 on Windows 7, Vista, Windows XP, Server 2003, Server 2008 R2, as well as IE 6 Service Pack 1 on Windows 2000 Service Pack 4.\n\nThe Internet Explorer exploit code used in the attack has been released into the public domain, and has been incorporated into the Metasploit Framework penetration testing tool. A copy of the exploit was uploaded to Wepawet, a service for detecting and analyzing web-based malware operated by the computer security group at the University of California, Santa Barbara. \"The public release of the exploit code increases the possibility of widespread attacks using the Internet Explorer vulnerability,\" said George Kurtz, CTO of McAfee, of the attack. \"The now public computer code may help cybercriminals craft attacks that use the vulnerability to compromise Windows systems.\"\n\nSecurity company Websense said it identified \"limited public use\" of the unpatched IE vulnerability in drive-by attacks against users who strayed onto malicious Web sites. According to Websense, the attack code it spotted is the same as the exploit that went public last week.[clarification needed] \"Internet Explorer users currently face a real and present danger due to the public disclosure of the vulnerability and release of attack code, increasing the possibility of widespread attacks,\" said George Kurtz, chief technology officer of McAfee, in a blog update. Confirming this speculation, Websense Security Labs identified additional sites using the exploit on January 19. According to reports from Ahnlab, the second URL was spread through the Instant Messenger network Misslee Messenger, a popular IM client in South Korea.\n\nResearchers have created attack code that exploits the vulnerability in Internet Explorer 7 (IE7) and IE8—even when Microsoft's recommended defensive measure (Data Execution Prevention (DEP)) is turned on.[dubious – discuss] According to Dino Dai Zovi, a security vulnerability researcher, \"even the newest IE8 isn't safe from attack if it's running on Windows XP Service Pack 2 (SP2) or earlier, or on Windows Vista RTM (release to manufacturing), the version Microsoft shipped in January 2007.\"\n\nMicrosoft admitted that the security hole used had been known to them since September. Work on an update was prioritized and on Thursday, January 21, 2010, Microsoft released a security patch aiming to counter this weakness, the published exploits based on it and a number of other privately reported vulnerabilities. They did not state if any of the latter had been used or published by exploiters or whether these had any particular relation to the Aurora operation, but the entire cumulative update was termed critical for most versions of Windows, including Windows 7.\n\nSecurity researchers continued to investigate the attacks. HBGary, a security firm, released a report in which they claimed to have found some significant markers that might help identify the code developer. The firm also said that the code was Chinese language based but could not be specifically tied to any government entity.\n\nOn February 19, 2010, a security expert investigating the cyber-attack on Google, has claimed that the people behind the attack were also responsible for the cyber-attacks made on several Fortune 100 companies in the past one and a half years. They have also tracked the attack back to its point of origin, which seems to be two Chinese schools, Shanghai Jiao Tong University and Lanxiang Vocational School. As highlighted by The New York Times, both of these schools have ties with the Chinese search engine Baidu, a rival of Google China. Both Lanxiang Vocational and Jiaotong University have denied the allegation.\n\nIn March 2010, Symantec, which was helping investigate the attack for Google, identified Shaoxing as the source of 21.3% of all (12 billion) malicious emails sent throughout the world.\n\nGoogle retrospective\nOn October 3, 2022, Google on YouTube released a six-episode series covering the events that occurred during Operation Aurora, with commentary from insiders who dealt with the attack, though the series primary focus was to reassure the Google-using public that measures are in place to counter hacking attempts.",

        "evidence": "Hanlon's razor is an adage or rule of thumb that states, \"Never attribute to malice that which is adequately explained by stupidity.\" Known in several other forms, it is a philosophical razor that suggests a way of eliminating unlikely explanations for human behavior. It is probably named after Robert J. Hanlon, who submitted the statement to Murphy's Law Book Two (1980). Similar statements have been recorded since at least the 18th century.\n\nOrigin\nA similar quotation appears in Robert A. Heinlein's novella Logic of Empire (1941). The character \"Doc\" in Heinlein's story described the \"devil theory\" fallacy, explaining, \"You have attributed conditions to villainy that simply result from stupidity.\"\n\nThe quotation as such was a submission credited in print to Robert J. Hanlon of Scranton, Pennsylvania, for a compilation of various jokes related to Murphy's law that were published in Arthur Bloch's Murphy's Law Book Two: More Reasons Why Things Go Wrong! (1980). It is unknown whether Hanlon knew of Heinlein's story or whether he independently constructed the phrase.[citation needed]\n\nHanlon's razor became well-known after its inclusion in the Jargon File, a glossary of computer programmer slang, since 1990. Later that same year, the Jargon File editors noted lack of knowledge about the term's derivation and the existence of a similar epigram by William James, though this was possibly intended as a reference to William James Laidlay. In 1996, the Jargon File entry on Hanlon's Razor noted the existence of the phrase in Heinlein's novella, with speculation that Hanlon's Razor might be a corruption of \"Heinlein's Razor\". The link to Murphy's law was described in a pair of 2001 blog entries by Quentin Stafford-Fraser, citing emails from Joseph E. Bigler. Subsequently, in 2002, the Jargon File entry noted the same.

        "question": "What is a console war in video games?",
        "evidence": "In the video game industry, a console war describes the competition between two or more video game console manufacturers in trying to achieve better consumer sales through more advanced console technology, an improved selection of video games, and general marketing around their consoles. While console manufacturers are generally always trying to out-perform other manufacturers in sales, these console wars engage in more direct tactics to compare their offerings directly against their competitors or to disparage the competition in contrast to their own, and thus the marketing efforts have tended to escalate in back-and-forth pushes.\n\nWhile there have been many console wars to date, the term became popular between Sega and Nintendo during the late 1980s and early 1990s as Sega attempted to break into the United States video game market with its Sega Genesis console. Through a novel marketing approach and improved hardware, Sega had been able to gain a majority of the video game console market by 1991, three years after the Genesis’ launch. This caused back and forth competition between the two companies throughout the early 1990s. However, Nintendo eventually regained its market share and Sega stopped making home console hardware by 2001.",
        "answer": "The video game console market started in 1972 with the release of the first home console, the Magnavox Odyssey. As more manufacturers entered the market and technology improved, the market began to coalesce around the concept of console generations, groupings of consoles with similar technical specifications that vied in the consumer marketplace. Since 1972, there have been nine such console generations, with two to three dominant manufacturers controlling the marketplace as an oligopoly.\n\nAs with most industries without a single dominant leader, console manufacturers have marketed their products in a manner to highlight them in a more favorable manner compared to their competitors', or to focus on features that their competitors may lack, often in aggressive manners. For example, console manufacturers in the 1980s and 1990s heavily relied on the word size of the central processor unit, emphasizing that games had better capabilities with 16-bit processors over 8-bit ones. This type of aggressive marketing led video game journalists to call the competitive marketing a \"war\" or \"battle\" as early as August 1988. As each new console generation emerged with new marketing approaches, journalists and consumers continued to use variations of the \"war\" language, including \"system wars\" and \"console wars\". By the early 2000s, the term \"console war\" was most commonly used to describe heated competition between console manufacturers within any generation.\n\nWhile not the only console war, the rivalry between Sega and Nintendo for dominance of the North American video game market in the late 1980s and early 1990s is generally the most visible example of a console war. It established the use of aggressive marketing and advertising tactics by each company to try to gain control of the marketplace, and ended around 1995 when a new player, Sony, entered and disrupted the console space.\n\nThe United States video game industry suffered a severe market crash in 1983 from numerous factors which led to a larger market recession and increasing popularity of personal computers as a video game platform. A key contributing factor to the crash was the loss of publishing control for console games. Early success by some of the first third-party developers like Activision for the Atari VCS console led to venture capitalists bringing in teams of inexperienced programmers to try to capture the same success, but only managed to flood the market with poor quality games, which made it difficult for good quality games to sell. The video game crash impacted other factors in the industry that were already in decline, such as video game arcades.\n\nIn Japan, Nintendo had released its Famicom (Family Computer) console in 1983, one of the first consoles of the third generation or the \"8-bit\" generation. Japan did not have a similar third-party development system in place, and Nintendo maintained control on the manufacturing of game cartridges for the Famicom using a licensing model to limit which third-party games were published on it. The Famicom did launch with a technical fault that Nintendo scrambled to fix, but by the end of 1984, the Famicom was the best-selling console in Japan. Nintendo looked to release the unit in the United States, but recognized that the market was still struggling from the 1983 crash. Nintendo took several steps to redesign the Famicom prior to a United States launch. It was made to look like a VCR unit rather than a console, and was given the name the \"Nintendo Entertainment System\" to distance it from being a video game console. Further, Nintendo added a special 10NES lockout system that worked as a lock-and-key system with game cartridges to further prevent unauthorized games from being published for the system and avoid the loss of publishing control that had caused the 1983 crash. The NES revitalized the U.S. video game industry and established Nintendo as the dominant name in video game consoles over Atari. In lifetime sales, the NES had sold nearly 62 million units worldwide, with 34 million in North America.\nAt the same time, Sega was looking to get into the video game console industry as well, having been a successful arcade game manufacturer, but due to the downturn in arcade game business, looked to use that expertise for the home market. They released the SG-1000 console in Japan the same day as the Famicom in 1983, but sold only 160,000 units of the SG-1000 in its first year.\n\nSega redesigned the SG-1000 twice to try to build a system to challenge Nintendo's dominance; the SG-1000 Mark II remained compatible with the SG-1000 but failed to gain any further sales. The next iteration, the Sega Mark III, was released in 1985, using Sega's arcade hardware for its internals to provide more refined graphics. The console was slightly more powerful than the Famicom, and Sega's marketing attempted to push on the more advanced graphics their system offered over the Famicom. However, Sega found that Nintendo had also contracted other developers to only develop their games exclusive to the Famicom, and Sega was forced to develop their own titles or to port the games from the other developers themselves, limiting the size of the Mark III's library in Japan. Sega attempted to follow Nintendo with a worldwide release of the Mark III, rebranded as the Master System. The Master System was released in the United States in 1986, but Nintendo had similar licensing practices in the U.S. to keep developers exclusive to the NES, limiting the library of games that Sega could offer and to also ensure that another gaming crash didn't begin. Further, Sega's third-party distributor, the toy company Tonka, opted against localizing several of the Japanese games Sega had created, further capping the game library Sega could offer in the U.S. Only a total estimated two million systems were sold.\n\nThe Sega and Nintendo console war primarily centered on the launch of the Sega Genesis to try to outsell the Nintendo Entertainment System in the United States.\nThe fourth generation of video game consoles was started by the launch of NEC's PC Engine in 1987 in Japan. While the PC Engine used an 8-bit CPU, it included 16-bit graphic rendering components, and NEC marketed this heavily as a 16-bit game console to distinguish it from the Famicom and Mark III; when NEC brought the PC Engine worldwide, it was rebranded as the \"TurboGrafx-16\" to emphasize this. After the release of the TurboGrafx-16, use of the bit designation caught on. Which led manufacturers to focus their advertising heavily on the number of bits in a console system for the next two console generations.\n\nNEC was another competitor to Sega and Nintendo. Following a similar path they had done for the Mark III, Sega used their arcade game technology, now using 16-bit processor boards, and adapted those into a home console, released in Japan in October 1988 as the Mega Drive. Compared to its prior consoles, the Mega Drive was designed to be more mature-looking and less like a toy compared to the Famicom to appeal to an older demographic of gamers, and \"16-bit\" was emblazoned on the console's case to emphasize this feature. While the system was positively received by gaming magazines like Famitsu, it was overshadowed by the release a week prior of Super Mario Bros. 3 for the Famicom.\n\nAs with the Master System, Sega also planned for a major push of the Mega Drive into the United States to challenge Nintendo's dominance among other markets, with the unit rebranded as the Sega Genesis. Sega was dissatisfied with Tonka's handling of the Master System and so sought a new partner through the Atari Corporation led by Jack Tramiel. Tramiel was bullish on the Genesis due to its cost, and turned down the offer, instead focusing more on the company's computer offerings. Sega instead used its dormant Sega of America branch to run a limited launch of the console in August 1989 in test markets of New York City and Los Angeles, with its launch system being bundled with the port of the arcade game Altered Beast.\n\nIn October 1989, the company named former Atari Entertainment Electronics Division president Michael Katz as CEO of Sega of America to implement a marketing strategy for a nation-wide push of the Genesis with a target of one million consoles. Katz used a two-prong strategy to challenge Nintendo. The first was to stress the arcade-like capabilities of the Genesis with the capabilities of games like Altered Beast compared to the simpler 8-bit graphics of the NES, and devising slogans such as \"Genesis does what Nintendon't.\"Katz also observed that Nintendo still held most of the rights to arcade game ports for the NES, so the second part of his strategy was to work with the Japanese headquarters of Sega to pay celebrities for their naming rights for games like Pat Riley Basketball, Arnold Palmer Golf, Joe Montana Football, and Michael Jackson's Moonwalker.\n\nMost of these games were developed by Sega's Japanese programmers, though notably, Joe Montana Football had originally been developed by Mediagenic, the new name for Activision after it had become more involved in publishing and business application development alongside games. Mediagenic had started a football game which Katz wanted to brand under Joe Montana's name, but unknown to Katz at the time, the game was only partially finished due to internal strife at Mediagenic. After the deal had been completed and Katz learned of this, he took the game to Electronic Arts. Electronic Arts had already made itself a significant force in the industry as they had been able to reverse engineer the cartridge format for both the NES and the Genesis, though Electronic Arts' CEO Trip Hawkins felt it was better for the company to develop for the Genesis. Electronic Arts used their reverse engineering knowledge as part of their negotiations with Sega to secure a freer licensing contract to develop openly on the Genesis, which proved beneficial for both companies. At the time Katz had secured Mediagenic's Joe Montana football, Electronic Arts was working on its John Madden Football series for personal computers. Electronic Arts was able to help bring Joe Montana Football, more as an arcade title compared to the strategic John Madden Football, to reality, as well as bringing John Madden Football over as a Genesis title.\n\nThe second push in 1991\nThe Genesis still struggled in the United States against Nintendo, and only sold about 500,000 units by mid-1990. Nintendo had released Super Mario Bros. 3 in February 1990 which further drove sales away from Sega's system. Nintendo themselves did not seem to be affected by either Sega's or NEC's entry into the console market. Sega's president Hayao Nakayama wanted the company to develop an iconic mascot character and build a game around it as one means to challenge Nintendo's own Mario mascot. Company artist Naoto Ohshima came up with the concept of Sonic the Hedgehog, a fast anthropomorphic character with an \"attitude\" that would appeal to teenagers and incorporating the blue color of Sega's logo, and Yuji Naka helped to develop the game Sonic the Hedgehog to showcase the character as well as the graphics and processing speed of the Genesis.The game was ready by early 1991 and launched in North America in June 1991.\n\nSeparately, Sega fired Katz and replaced him with Tom Kalinske as Sega of America's new CEO in mid-1990. Kalinske had been president of Mattel and did not have much experience in video games but recognized the razor and blades model, and developed a new strategy for Sega's push to challenge Nintendo's dominance in America with four key decisions, which included cutting the price of the Genesis from $189 to $149, and continue the same aggressive marketing campaigns to make the Genesis look \"cool\" over the NES and of Nintendo's upcoming Super Nintendo Entertainment System (SNES). Further, Kalinske pushed hard for American developers like Electronic Arts to create games on the Genesis that would better fit American preferences, particularly sports simulation games which the console had gained a reputation for. Finally, Kalinske insisted on making Sonic the Hedgehog the bundled game on the system following its release in June 1991, replacing Altered Beast and even offering those that had purchased a Genesis with Altered Beast a trade-in replacement for Sonic.\n\nUnder Kalinske, Sega also revamped their advertising approach, aiming for more of a young adult audience, as Nintendo still was positioning the SNES as a child-friendly console. Advertising focused on Sonic, the edgier games in the Genesis library, and its larger library of sports games which appealed to this group. Television ads for the Genesis and its games ended with the \"Sega Scream\" – a character shouting the name \"Sega\" to the camera in the final shot – which also caught on quickly.\n\nThese changes, all predating the SNES's planned North American release in September 1991, gave Sega its first gain on Nintendo in the U.S. market. Further, the price cut to $149 made the Genesis a cheaper option than the planned $199 price for the SNES led many families to purchase the Genesis instead of waiting for the SNES. The Genesis had a larger library of games for the U.S. with over 150 titles by the time the SNES launched alongside eight games, and Sega continued to push out titles that drew continuous press throughout the year, whereas with the SNES, its game library was generally held up by flagship Mario and Zelda games that only came at out once a year, along with less which further made the Genesis a more desirable option.\n\nFor Nintendo, up until 1991, they had been passive towards Sega's approach in North America, but as the SNES launch approach, the company recognized that they were losing ground. The company shifted their advertising in North America to focus on more of the advanced features of the SNES that were not present in the Genesis, such as its Mode 7 to create simulated 3D perspective effects.The initial shipment of one million SNES units sold out quickly and a total of 3.4 million SNES were sold by the end of 1991, a record for a new console launch, but the Genesis maintained strong sales against the SNES. The Genesis's resilience against the SNES led several of Nintendo's third-party developers to break their exclusive development agreements with Nintendo and seek out licenses to also develop for Genesis. Including Acclaim, Konami, Tecmo, Taito, and Capcom. The latter of which arranged to have a special licensing mechanism with Sega, allowing them to publish select titles exclusively for the Genesis.\n\nDuring this period, the push for marketing by both Nintendo and Sega led to the growth of video game magazines. Nintendo had already established Nintendo Power in 1988 in part to serve as a help guide for players on its popular titles, and was able to use this further to advertise the SNES and upcoming games. Numerous other titles grew in the late 1980s and early 1990s, giving Sega the opportunity to market its games heavily in these publications.\n\nThe war escalates in 1992 and 1993\nNintendo publicly acknowledged that it knew it was no longer in the dominant position in the console market by 1992. A year into the SNES's release, the SNES's price was lowered to $149 to match the Genesis, to which Sega reduced the Genesis to $129 shortly after. The SNES was helped by Capcom's decision to maintain exclusivity of its home port of its popular brawler arcade game Street Fighter II: The World Warrior to the SNES when it was released in June 1992. While the SNES outsold the Genesis in the U.S. in 1992. the Genesis still had a larger install base. By the start of 1993, the Genesis had captured about 55% of the market, a stark contrast to 1990 when Nintendo had controlled 90% of the market.\n\nThe success of Street Fighter II both as an arcade game and as a home console title led to the growth of the fighting game genre, and numerous variations from other developers followed. Of significant interest was Midway's Mortal Kombat, released to arcades in 1992. Compared to most other fighting games at the time, Mortal Kombat was much more violent. The game showed combatants’ blood splatter during combat and allowed players to end matches in graphically intense \"fatalities.” Because of its controversial style and gameplay, the game proved extremely popular in arcades.\nBy 1993, Both Nintendo and Sega recognized the need to have Mortal Kombat on their consoles. However, Nintendo, fearing issues with the game’s violence, licensed a “clean” version of the game from Acclaim for the SNES. Which included replacing the blood splatter with sweat and removing the aforementioned fatalities. Sega also licensed a censored version of the game for the Genesis. However, players could enter a cheat code that reverted the game back to its original arcade version. Both home versions were released in September, and approximately 6.5 million units were sold over the game’s lifetime. But the Genesis version was more popular with three to five times more sales than its SNES counterpart.\n\nExternal video\nvideo icon C-SPAN footage of the first congressional hearing on December 9, 1993.\nThe popularity of the home console version of Mortal Kombat, coupled with other moral panics in the early 1990s, led to concerns from parents, activists and lawmakers in the United States, leading up to the 1993 congressional hearings on video games first held in December. Led by Senators Joe Lieberman and Herb Kohl, the Senate Committees on Governmental Affairs and the Judiciary brought several of the video game industry leaders, including Howard Lincoln, vice president of Nintendo of America, and Bill White, vice president of Sega of America, to discuss the way they marketed games like Mortal Kombat and Night Trap on consoles to children. Lincoln and White accused each other's companies of creating the issue at hand. Lincoln stated that Nintendo had taken a curated approach to selecting games for their consoles, and that violent games had no place in the market. White responded that Sega purposely was targeting an older audience than Nintendo, and had created a ratings system for its games that it had been trying to encourage the rest of the industry to use; further, despite Nintendo's oversight, White pointed out that there were still many Nintendo titles that incorporated violence.With neither Lincoln nor White giving much play, Lieberman concluded the first hearing with a warning that the industry needs to come together with some means to regulate video games or else Congress would pass laws to do this for them.\n\nBy the time of the second hearing in March 1994, the industry had come together to form the Interactive Digital Software Association (today the Entertainment Software Association) and were working to establish the Entertainment Software Rating Board (ESRB), a ratings panel, which ultimately was introduced by September 1994. Despite Sega offering its ratings system as a starting point, Nintendo refused to work with that as they still saw Sega as their rival, requiring a wholly new system to be created. The ESRB eventually established a form modelled off the Motion Picture Association of America (MPAA)'s rating system for film, and the committee was satisfied with the proposed system and allowed the video game industry to continue without further regulations.\n\nThe arrival of Sony and the end of the war\n\n\n\nThe Sega Saturn (top) and Nintendo 64 (middle) struggled against Sony's newcomer, the PlayStation, which ultimately ended Sega and Nintendo's console war.\nIn 1994 and 1995, there was a contraction in the video game industry, with NPD Group reporting a 17% and 19% year-to-year drop in revenue. While Sega had been outperforming Nintendo in 1993, it still carried corporate debt while Nintendo remained debt-free from having a more dominant position in the worldwide market, even beating Sega in the North American and US market winning the 16 bit console war. To continue to fight Nintendo, Sega's next console was the Sega Saturn, first released in November 1994 in Japan. It brought in technology used by Sega's arcade games that used 3d polygonal graphics, and launch titles featured home versions of these arcade games including Virtua Fighter. While Virtua Fighter was not a pack-in game, sales of the title were nearly 1:1 with the console in Japan. Sega, recognizing that they had numerous consoles with disparate games they were now trying to support, decided to put most of their attention onto the Saturn line going forward, dropping support for the Genesis despite its sales still being strong in the United States at the time.\n\nAt the same time, a new competitor in the console marketplace emerged, Sony Computer Entertainment, with the introduction of the PlayStation in December 1994. Sega, aware of Sony's potential competition in Japan, made sure to have enough Saturns ready for sale on the day the PlayStation first shipped as to overwhelm Sony's offering.\n\nBoth Sega and Sony turned to move these units to the North American market. With the formation of the ISDA, a new North American tradeshow, the Electronic Entertainment Expo (E3) was created in 1995 to focus on video games, to distinguish it from the Consumer Electronics Show (CES), which covered all home electronics. Nintendo, Sega and Sony gave their full support to E3 in 1995. Sega believed they had the stronger position going into E3 over Sony, as gaming publications, comparing the Saturn to the PlayStation, rated the Saturn as the better system. At the first E3 in May 1995, Sega's Kalinske premiered the North American version of the Saturn, announced its various features and its selling price of $399, and said that while it would officially launch that same day, they had already sent a number of systems to selected vendors for sale. Sony's Olaf Olafsson of Sony Electronic Publishing began to cover the PlayStation features, then invited Steve Race, president of Sony Computer Entertainment America to the stage. Race stated the launch price of the PlayStation, \"$299\", and then left to \"thunderous applause\". The surprise price cut caught Sega off-guard, and, in addition to several stores pulling Sega from their lineup due to being shunned from early Saturn sales, the higher price point made it more difficult for them to sell the system. When the PlayStation officially launched in the United States in September 1995, its sales over the first two days exceeded what the Saturn had sold over the prior five months. Because Sega had invested heavily on Saturn into the future, Sony's competition drastically hurt the company's finances.\n\nIn the case of Nintendo, they bypassed the 32-bit CPU and instead their next offering was the Nintendo 64, a 64-bit CPU console first released in June 1996. While this gave them powerful capabilities such as 3D graphics to keep up and surpass those on the Saturn and PlayStation, it was still a cartridge-based system limiting how much information could be stored for each game. This decision ultimately cost them Square Soft who moved their popular Final Fantasy series over to the PlayStation line to take advantage of the larger space on optical media. The first PlayStation game in the series, Final Fantasy VII, drove sales of the PlayStation, further weakening Nintendo's position and driving Sega further out of the market.\n\nBy this point, the console war between Nintendo and Sega had evaporated, with both companies now facing Sony as their rival. Sega made one more console, the Dreamcast, which had a number of innovative features including a built-in modem for online connectivity, but the console's lifespan was short-lived in part due to the success of Sony's next product, the PlayStation 2, one of the best-selling home consoles of all time. Sega left the home console hardware business in 2001 to focus on software development and licensing. Nintendo remains a key player in the home console business, but more recently has taken a \"blue ocean strategy\" approach to avoid competing directly with Sony or Microsoft on a feature-for-feature basis with consoles like the Wii, Nintendo DS, and Nintendo Switch.\n\n\nThe Sega/Nintendo console war is the subject of the non-fiction novel Console Wars by Blake Harris in 2014, as well as a film adaption/documentary of the book in 2020.\n\nSega and Nintendo have since collaborated on various software titles. Sega has developed a biennial Mario & Sonic at the Olympics series of sports games based on the Summer and Winter Olympics since 2008 featuring characters from both the Super Mario and Sonic series, while Nintendo has developed the Super Smash Bros. crossover fighter series for numerous Nintendo properties that has included Sonic as a playable character along with other Sonic characters in supporting roles since Super Smash Bros. Brawl.\n\n\n\n\n1990s handheld consoles.\nA number of major handheld consoles were released on the market within about a year of each other: Nintendo's Game Boy, Sega's Game Gear, and the Atari Lynx. While the Game Boy used a monochromatic display, both the Game Gear and Lynx had colour displays. As these handheld releases were alongside the Sega v. Nintendo console war, they were also subject to heavy marketing and advertising to try to draw consumersHowever, the Game Boy ultimately won out in this battle, selling over 118 million units over its lifetime (including its future revisions) compared to 10 million for the Game Gear and 3 million for the Lynx. The Game Boy initially sold for $50 or more cheaper than its competitors, and had a larger library of games, including what is considered the handheld's killer app, Tetris, that drew non-gamers to purchase the handheld to play it.\n\n\nThe Hyperdimension Neptunia series of video games started as a parody of the console wars, incorporating personified consoles, developers, consumers, and other such figures within the gaming industry.",

        "evidence": "The proliferation of the online social media has lately resulted in the democratization of online content sharing. Among other media, Twitter is very popular for research and application purposes due to its scale, representativeness and ease of public access to its content. However, tweets, that are short messages of up to 140 characters, pose several challenges to traditional Natural Language Processing (NLP) systems due to the creative use of characters and punctuation symbols, abbreviations ans slung language.\nNamed Entity Recognition (NER) is a fundamental step for most of the information extraction pipelines. Importantly, the terse and difficult text style of tweets presents serious challenges to NER systems, which are usually trained using more formal text sources such as newswire articles or Wikipedia entries that follow particular morpho-syntactic rules. As a result, off-the-self tools trained on such data perform poorly BIBREF0 . The problem becomes more intense as the number of entities to be identified increases, moving from the traditional setting of very few entities (persons, organization, time, location) to problems with more. Furthermore, most of the resources (e.g., software tools) and benchmarks for NER are for text written in English. As the multilingual content online increases, and English may not be anymore the lingua franca of the Web. Therefore, having resources and benchmarks in other languages is crucial for enabling information access worldwide.\nIn this paper, we propose a new benchmark for the problem of NER for tweets written in French. The tweets were collected using the publicly available Twitter API and annotated with 13 types of entities. The annotators were native speakers of French and had previous experience in the task of NER. Overall, the generated datasets consists of INLINEFORM0 tweets, split in training and test parts.\nThe paper is organized in two parts.

        "question": "What new problem does the paper propose?",
        "answer": "A new problem of open-world knowledge base completion (OKBC).",
        "evidence": "Chatbots such as dialog and question-answering systems have a long history in AI and natural language processing. Early such systems were mostly built using markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Recent neural conversation models BIBREF4 , BIBREF5 , BIBREF6 are even able to perform open-ended conversations. However, since they do not use explicit knowledge bases and do not perform inference, they often suffer from generic and dull responses BIBREF5 , BIBREF7 . More recently, BIBREF8 and BIBREF9 proposed to use knowledge bases (KBs) to help generate responses for knowledge-grounded conversation. However, one major weakness of all existing chat systems is that they do not explicitly or implicitly learn new knowledge in the conversation process. This seriously limits the scope of their applications. In contrast, we humans constantly learn new knowledge in our conversations. Even if some existing systems can use very large knowledge bases either harvested from a large data source such as the Web or built manually, these KBs still miss a large number of facts (knowledge) BIBREF10 . It is thus important for a chatbot to continuously learn new knowledge in the conversation process to expand its KB and to improve its conversation ability.\nIn recent years, researchers have studied the problem of KB completion, i.e., inferring new facts (knowledge) automatically from existing facts in a KB. KB completion (KBC) is defined as a binary classification problem: Given a query triple, ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ), we want to predict whether the source entity INLINEFORM3 and target entity INLINEFORM4 can be linked by the relation INLINEFORM5 . However, existing approaches BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 solve this problem under the closed-world assumption, i.e., INLINEFORM6 , INLINEFORM7 and INLINEFORM8 are all known to exist in the KB. This is a major weakness because it means that no new knowledge or facts may contain unknown entities or relations. Due to this limitation, KBC is clearly not sufficient for knowledge learning in conversations because in a conversation, the user can say anything, which may contain entities and relations that are not already in the KB.\nIn this paper, we remove this assumption of KBC, and allow all INLINEFORM0 , INLINEFORM1 and INLINEFORM2 to be unknown. We call the new problem open-world knowledge base completion (OKBC). OKBC generalizes KBC. Below, we show that solving OKBC naturally provides the ground for knowledge learning and inference in conversations. In essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.\nFrom the perspective of knowledge learning in conversations, essentially we can extract two key types of information, true facts and queries, from the user utterances. Queries are facts whose truth values need to be determined. Note that we do not study fact or relation extraction in this paper as there is an extensive work on the topic. (1) For a true fact, we will incorporate it into the KB. Here we need to make sure that it is not already in the KB, which involves relation resolution and entity linking. After a fact is added to the KB, we may predict that some related facts involving some existing relations in the KB may also be true (not logical implications as they can be automatically inferred). For example, if the user says “Obama was born in USA,” the system may guess that (Obama, CitizenOf, USA) (meaning that Obama is a citizen of USA) could also be true based on the current KB. To verify this fact, it needs to solve a KBC problem by treating (Obama, CitizenOf, USA) as a query. This is a KBC problem because the fact (Obama, BornIn, USA) extracted from the original sentence has been added to the KB. Then Obama and USA are in the KB. If the KBC problem is solved, it learns a new fact (Obama, CitizenOf, USA) in addition to the extracted fact (Obama, BornIn, USA). (2) For a query fact, e.g., (Obama, BornIn, USA) extracted from the user question “Was Obama born in USA?” we need to solve the OKBC problem if any of “Obama, “BornIn”, or “USA\" is not already in the KB.\nWe can see that OKBC is the core of a knowledge learning engine for conversation. Thus, in this paper, we focus on solving it. We assume that other tasks such as fact/relation extraction and resolution and guessing of related facts of an extracted fact are solved by other sub-systems.\nWe solve the OKBC problem by mimicking how humans acquire knowledge and perform reasoning in an interactive conversation. Whenever we encounter an unknown concept or relation while answering a query, we perform inference using our existing knowledge. If our knowledge does not allow us to draw a conclusion, we typically ask questions to others to acquire related knowledge and use it in inference. The process typically involves an inference strategy (a sequence of actions), which interleaves a sequence of processing and interactive actions. A processing action can be the selection of related facts, deriving inference chain, etc., that advances the inference process. An interactive action can be deciding what to ask, formulating a suitable question, etc., that enable us to interact. The process helps grow the knowledge over time and the gained knowledge enables us to communicate better in the future. We call this lifelong interactive learning and inference (LiLi). Lifelong learning is reflected by the facts that the newly acquired facts are retained in the KB and used in inference for future queries, and that the accumulated knowledge in addition to the updated KB including past inference performances are leveraged to guide future interaction and learning. LiLi should have the following capabilities:\nThis setting is ideal for many NLP applications like dialog and question-answering systems that naturally provide the scope for human interaction and demand real-time inference.\nLiLi starts with the closed-world KBC approach path-ranking (PR) BIBREF11 , BIBREF17 and extends KBC in a major way to open-world knowledge base completion (OKBC). For a relation INLINEFORM0 , PR works by enumerating paths (except single-link path INLINEFORM1 ) between entity-pairs linked by INLINEFORM2 in the KB and use them as features to train a binary classifier to predict whether a query INLINEFORM3 should be in the KB. Here, a path between two entities is a sequence of relations linking them. In our work, we adopt the latest PR method, C-PR BIBREF16 and extend it to make it work in the open-world setting. C-PR enumerates paths by performing bidirectional random walks over the KB graph while leveraging the context of the source-target entity-pair. We also adopt and extend the compositional vector space model BIBREF20 , BIBREF21 with continual learning capability for prediction.\nGiven an OKBC query ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ) (e.g., “(Obama, CitizenOf, USA), which means whether Obama a citizen of USA), LiLi interacts with the user (if needed) by dynamically formulating questions (see the interaction example in Figure 1, which will be further explained in §3) and leverages the interactively acquired knowledge (supporting facts (SFs) in the figure) for continued inference. To do so, LiLi formulates a query-specific inference strategy and executes it. We design LiLi in a Reinforcement Learning (RL) setting that performs sub-tasks like formulating and executing strategy, training a prediction model for inference, and knowledge retention for future use. To the best of our knowledge, our work is the first to address the OKBC problem and to propose an interactive learning mechanism to solve it in a continuous or lifelong manner. We empirically verify the effectiveness of LiLi on two standard real-world KBs: Freebase and WordNet. Experimental results show that LiLi is highly effective in terms of its predictive performance and strategy formulation ability.\nIn this paper, we remove this assumption of KBC, and allow all INLINEFORM0 , INLINEFORM1 and INLINEFORM2 to be unknown. We call the new problem open-world knowledge base completion (OKBC).",

In most cases multipurpose trees have a primary role; such as being part of a living fence, or a windbreak, or used in an ally cropping system. In addition to this they will have one or more secondary roles, most often supplying a family with food or firewood, or both.\n\nWhen a multipurpose tree is planted, a number of needs and functions can be fulfilled at once. They may be used as a windbreak, while also supplying a staple food for the owner. They may be used as fencepost in a living fence, while also being the main source of firewood for the owner. They may be intercropped into existing fields, to supply nitrogen to the soil, and at the same time serve as a source of both food and firewood.\n\nCommon multipurpose trees of the tropics include:\n\nGliricidia (Gliricidia sepium) – the most common tree used for living fences in Central America, firewood, fodder, fixing nitrogen into the soil.\nMoringa (Moringa oleifera) – edible leaves, pods and beans, commonly used for animal forage and shade (it does not fix nitrogen as is commonly believed)\nCoconut palm (Cocos nucifera) – used for food, purified water (juice from inside the coconut), roof thatching, firewood, shade.\nNeem (Azadirachta indica) – limited use as insect repellent, antibiotic, adding nitrogen to the soil, windbreaks, biomass production for use as mulch, firewood.\nIdeally most trees found on tropical farms should be multipurpose, and provide more to the farmer than simply shade and firewood.

But high-quality ASR requires hundreds of hours of transcribed audio, while high-quality MT requires millions of words of parallel text—resources available for only a tiny fraction of the world's estimated 7,000 languages BIBREF1 . Nevertheless, there are important low-resource settings in which even limited speech translation would be of immense value: documentation of endangered languages, which often have no writing system BIBREF2 , BIBREF3 ; and crisis response, for which text applications have proven useful BIBREF4 , but only help literate populations. In these settings, target translations may be available. For example, ad hoc translations may be collected in support of relief operations. Can we do anything at all with this data?\nIn this exploratory study, we present a speech-to-text translation system that learns directly from source audio and target text pairs, and does not require intermediate ASR or MT. Our work complements several lines of related recent work. For example, duong2015attentional and antonios+chiang+duongEMNLP2016 presented models that align audio to translated text, but neither used these models to try to translate new utterances (in fact, the latter model cannot make such predictions). berard+etalnipsworkshop16 did develop a direct speech to translation system, but presented results only on a corpus of synthetic audio with a small number of speakers. Finally, Adams et al. adams+etalinterspeech16,adams+etalemnlp16 targeted the same low-resource speech-to-translation task, but instead of working with audio, they started from word or phoneme lattices. In principle these could be produced in an unsupervised or minimally-supervised way, but in practice they used supervised ASR/phone recognition. Additionally, their evaluation focused on phone error rate rather than translation. In contrast to these approaches, our method can make translation predictions for audio input not seen during training, and we evaluate it on real multi-speaker speech data.\nOur simple system (§ SECREF2 ) builds on unsupervised speech processing BIBREF5 , BIBREF6 , BIBREF7 , and in particular on unsupervised term discovery (UTD), which creates hard clusters of repeated word-like units in raw speech BIBREF8 , BIBREF9 . The clusters do not account for all of the audio, but we can use them to simulate a partial, noisy transcription, or pseudotext, which we pair with translations to learn a bag-of-words translation model. We test our system on the CALLHOME Spanish-English speech translation corpus BIBREF10 , a noisy multi-speaker corpus of telephone calls in a variety of Spanish dialects (§ SECREF3 ). Using the Spanish speech as the source and English text translations as the target, we identify several challenges in the use of UTD, including low coverage of audio and difficulty in cross-speaker clustering (§ SECREF4 ). Despite these difficulties, we demonstrate that the system learns to translate some content words (§ SECREF5 ).\nOur work complements several lines of related recent work.",

        "question": "What do the Entities mean in OWL?",
        "answer": "Entities, such as classes, properties, and individuals, are identified by IRIs. They form the primitive terms and constitute the basic elements of an ontology.",
        "evidence": "OWL BIBREF15 is the de-facto standard for machine processable and interoperable ontologies on the SW. In its second version, OWL is equivalent to the description logic $\\mathcal {SROIQ}(D)$. Such expressiveness has a higher computational cost but allows the development of interesting applications such as automated reasoning BIBREF16. OWL 2 ontologies consist of the following three different syntactic categories:\nEntities, such as classes, properties, and individuals, are identified by IRIs. They form the primitive terms and constitute the basic elements of an ontology. Classes denote sets of individuals and properties link two individuals or an individual and a data value along a property. For example, a class :Animal can be used to represent the set of all animals. Similarly, the object property :childOf can be used to represent the parent-child relationship and the data property :birthDate assigns a particular birth date to an individual. Finally, the individual :Alice can be used to represent a particular person called \"Alice\".\nExpressions represent complex notions in the domain being described. For example, a class expression describes a set of individuals in terms of the restrictions on the individuals' characteristics. OWL offers existential (SOME) or universal (ONLY) qualifiers and a variety of typical logical constructs, such as negation (NOT), other Boolean operators (OR, AND), and more constructs such as cardinality restriction (MIN, MAX, EXACTLY) and value restriction (VALUE), to create class expressions. Such constructs can be combined in arbitrarily complex class expressions CE according to the following grammar\nwhere A is an atomic class, C and D are class expressions, R is an object property, a as well as a$_1$ to a$_m$ with $\\texttt {m} \\ge 1$ are individuals, and $\\texttt {n} \\ge 0$ is an integer.\nAxioms are statements that are asserted to be true in the domain being described. Usually, one distinguish between (1) terminological and (2) assertional axioms. (1) terminological axioms are used to describe the structure of the domain, i.e., the relationships between classes resp. class expressions. For example, using a subclass axiom (SubClassOf:), one can state that the class :Koala is a subclass of the class :Animal. Classes can be subclasses of other classes, thus creating a taxonomy. In addition, axioms can arrange properties in hierarchies (SubPropertyOf:) and can assign various characteristics (Characteristics:) such as transitivity or reflexivity to them. (2) Assertional axioms formulate facts about individuals, especially the classes they belong to and their mutual relationships. OWL can be expressed in various syntaxes with the most common computer readable syntax being RDF/XMLA more human-readable format is the MOS BIBREF17. For example, the class expression that models people who work at a university that is located in Spain could be as follows in MOS:\nLikewise, expressing that every professor works at a university would read as\nOWL 2 ontologies consist of Entities, Expressions and Axioms as introduced in subsec:owl. While both expressions and axioms can be mapped to RDF, i.e. into a set of RDF triples, using this mapping and applying the triple-based verbalization on it would lead to a non-human understandable text in many cases. For example, the intersection of two classes :A and :B can be represented in RDF by the six triples\nThe verbalization of these triples would result in Something that is a class and the intersection of something whose first is A and whose rest is something whose first is B and whose rest ist nil., which is obviously far away from how a human would express it in NL. Therefore, generating NL from OWL requires a different procedure based on its syntactic categories, OWL expressions and OWL axioms. We show the general rules for each of them in the following.\nIn theory, class expressions can be arbitrarily complex, but as it turned out in some previous analysis BIBREF22, in practice they seldom arise and can be seen as some corner cases. For example, an ontology could contain the following class expression about people and their birth place:\nClass expressions do have a tree-like structure and can simply be parsed into a tree by means of the binary OWL class expressions constructors contained in it. For our example, this would result in the following tree:\nevery tree node/.style=align=center,anchor=base,font=, edge from parent/.style= thick, draw, edge from parent path=(.south) – +(0,-8pt) -| () frontier/.style=distance from root=9 [.AND Person [.SOME birthPlace [.AND City [.VALUE locatedIn France ] ] ] ]\nSuch a tree can be traversed in post-order, i.e. sub-trees are processed before their parent nodes recursively. For the sake of simplicity, we only process sub-trees that represent proper class expression in our example, i.e. we omit birthPlace, locatedIn, and France. Moreover and again for simplicity, we'll explain the transformation process by starting from the right-hand side of the tree. Thus, in our example we begin with the class expression City which is transformed to everything that is a city and locatedIn VALUE France resulting in everything that is located in France by application of a rule. Both class expressions are used in the conjunction City AND locatedIn VALUE France. Thus, the next step would be to merge both phrases. An easy way is to use the coordinating conjunction and, i.e. everything that is a city and everything that is located in France. Although the output of this transformation is correct, it still contains unnecessarily redundant information. Therefore, we apply the aggregation procedure described in subsec:grouping, i.e. we get everything that is a city and located in France. Yet, the aggregation can still be improved: if there is any atomic class in the conjunction, we know that this is more specific than the placeholder everything. Thus, we can replace it by the plural form of the class, finally resulting in cities that are located in France. The same procedure is applied for its parent class expression being the existential restriction\nThis will be transformed to everything whose birth place is a city that is located in France. Note, that we used the singular form here, assuming that the property birthPlace is supposed to be functional in the ontology. In the last step, we process the class expression Person, which gives us everything that is a person. Again, due to the conjunction we merge this result with with the previous one, such that in the end we get people whose birth place is a city that is located in France.\nAs we described in sec:owl, OWL axioms can roughly be categorized into terminological and assertional axioms. Therefore, we have different procedures for processing each category:\nAssertional Axioms (ABox Axioms) - Most assertional axioms assert individuals to atomic classes or relate individuals to another individual resp. literal value. For example, axioms about the type as well as birth place and birth date of Albert Einstein can be expressed by\nThose axioms can simply be rewritten as triples, thus, we can use the same procedure as we do for triples (sec:singletriple). Converting them into NL gives us Albert Einstein is a person whose birth place is Ulm and whose birth date is 14 March 1879. OWL also allows for assigning an individual to a complex class expression. In that case we'll use our conversion of OWL class expressions as described in subsec:owlce.\nTerminological Axioms (TBox Axioms) - According to power2010, most of the terminological axioms used in ontologies are subclass axioms. By definition, subclass and superclass can be arbitrarily complex class expressions $\\texttt {CE}_1$ and $\\texttt {CE}_2$, i.e. [language=manchester,mathescape=true]CE$_1$ SubClassOf CE$_2$, but in praxis it is quite often only used with atomic classes as subclass or even more simple with the superclass also beeing an atomic class. Nevertheless, we support any kind of subclass axiom and all other logical OWL axioms in LD2NL. For simplicity, we outline here how we verbalize subclass axioms in LD2NL. The semantics of a subclass axiom denotes that every individual of the subclass also belongs to the superclass. Thus, the verbalization seems to be relatively straightforward, i.e. we verbalize both class expressions and follow the template : every $\\rho (\\texttt {\\texttt {CE}$1$})$ is a $\\rho (\\texttt {\\texttt {CE}$2$})$. Obviously, this works pretty well for subclass axioms with atomic classes only. For example, the axiom\nis verbalized as every scientist is a person.\nThis work was supported by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) through the projects LIMBO (no. 19F2029I) and OPAL (no. 19F2028A).

We note that two of the systems are supervised and rely on the training set to build their classification models. Document frequency counts are also computed on the training set. Stemming is applied to allow more robust matching. The different keyphrase extraction models are briefly described below:\nEach model uses a distinct keyphrase candidate selection method that provides a trade-off between the highest attainable recall and the size of set of candidates. Table summarizes these numbers for each model. Syntax-based selection heuristics, as used by TopicRank and WINGNUS, are better suited to prune candidates that are unlikely to be keyphrases. As for KP-miner, removing infrequent candidates may seem rather blunt, but it turns out to be a simple yet effective pruning method when dealing with long documents. For details on how candidate selection methods affect keyphrase extraction, please refer to BIBREF16 .\nApart from TopicRank that groups similar candidates into topics, the other models do not have any redundancy control mechanism. Yet, recent work has shown that up to 12% of the overall error made by state-of-the-art keyphrase extraction systems were due to redundancy BIBREF6 , BIBREF17 . Therefore as a post-ranking step, we remove redundant keyphrases from the ranked lists generated by all models. A keyphrase is considered redundant if it is included in another keyphrase that is ranked higher in the list.\nWe re-implemented five keyphrase extraction models : the first two are commonly used as baselines, the third is a resource-lean unsupervised graph-based ranking approach, and the last two were among the top performing systems in the SemEval-2010 keyphrase extraction task (Kim et al., 2010).",

Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed.\nSunset is distinct from twilight, which is divided into three stages. The first one is civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon. The second phase is nautical twilight, between 6 and 12 degrees below the horizon.

When compared to NER in the domain of general text, the biomedical domain has some characteristic challenges:\nSome of the earliest systems were heavily dependent on hand-crafted features. The method proposed in BIBREF4 for recognition of protein names in text does not require any prepared dictionary. The work gives examples of diversity in protein names and lists multiple rules depending on simple word features as well as POS tags.\n BIBREF5 adopt a machine learning approach for NER. Their NER system extracts medical problems, tests and treatments from discharge summaries and progress notes. They use a semi-Conditional Random Field (semi-CRF) BIBREF6 to output labels over all tokens in the sentence. They use a variety of token, context and sentence level features. They also use some concept mapping features using existing annotation tools, as well as Brown clustering to form 128 clusters over the unlabelled data. The dataset used is the i2b2 2010 challenge dataset. Their system achieves an F-Score of 0.85. BIBREF7 is an incremental paper on NER taggers. It uses 3 types of word-representation techniques (Brown clustering, distributional clustering, word vectors) to improve performance of the NER Conditional Random Field tagger, and achieves marginal F-Score improvements.\n BIBREF8 propose a boostrapping mechanism to bootstrap biomedical ontologies using NELL BIBREF9 , which uses a coupled semi-supervised bootstrapping approach to extract facts from text, given an ontology and a small number of “seed” examples for each category. This interesting approach (called BioNELL) uses an ontology of over 100 categories. In contrast to NELL, BioNELL does not contain any relations in the ontology. BioNELL is motivated by the fact that a lot of scientific literature available online is highly reliable due to peer-review. The authors note that the algorithm used by NELL to bootstrap fails in BioNELL due to ambiguities in biomedical literature, and heavy semantic drift. One of the causes for this is that often common words such as “white”, “dad”, “arm” are used as names of genes- this can easily result in semantic drift in one iteration of the bootstrapping. In order to mitigate this, they use Pointwise Mutual Information scores for corpus level statistics, which attributes a small score to common words. In addition, in contrast to NELL, BioNELL only uses high instances as seeds in the next iteration, but adds low ranking instances to the knowledge base. Since evaluation is not possible using Mechanical Turk or a small number of experts (due to the complexity of the task), they use Freebase BIBREF10 , a knowledge base that has some biomedical concepts as well. The lexicon learned using BioNELL is used to train an NER system. The system shows a very high precision, thereby showing that BioNELL learns very few ambiguous terms.\nMore recently, deep learning techniques have been developed to further enhance the performance of NER systems.

Once browned on that side, flip it and do not disturb it again until the other side is browned. This will help reduce the amount of liquid created in your skillet. If you do end up with too much liquid, and you want to reduce it due to seasonings and flavor that may be present, you can take the chicken out and put it on a plate.

        "answer": "It is a neural language model that utilizes character n-gram embeddings as an input in addition to a word embedding with simplified Multi-dimensional Self-attention (MS).",
        "evidence": "Categories such as animal or furniture are fundamental cognitive building blocks allowing humans to efficiently represent and communicate the complex world around them. Concepts (e.g., dog, table) are grouped into categories based on shared properties pertaining, for example, to their behavior, appearance, or function. Categorization underlies other cognitive functions such as perception BIBREF0 , BIBREF1 or language BIBREF2 , BIBREF3 , and there is evidence that categories are not only shaped by the world they represent, but also by the language through which they are communicated BIBREF4 , BIBREF5 . Although mental categories exist across communities and cultures, their exact manifestations differ BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 . For example, American English speakers prefer taxonomic categorizations (e.g., mouse,squirrel) while Chinese speakers tend to prefer to categorize objects relationally (e.g., tree, squirrel; BIBREF7 ).\nGiven their prevalent function in human cognition, the acquisition and representation of categories has attracted considerable attention in cognitive science, and numerous theories have emerged BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 . Empirical studies of category acquisition and representation, have been predominantly based on small-scale laboratory experiments. In a typical experiment, human subjects are presented with small sets of often artificial concepts, such as binary strings BIBREF14 or colored shapes BIBREF15 , with strictly controlled features BIBREF16 , BIBREF17 , BIBREF18 . Hypotheses and principles of human categorization are established based on the processes and characteristics of the categorizations produced by the participants. The distribution of subjects participating in such studies is often skewed towards members of cultural and socioeconomic groups which are prevalent in the environment where the research is conducted, and typically consists to a large proportion of western, educated, wealthy and English-speaking participants often sampled from the even more specific population of college students. The demographic and socioeconomic bias has been long recognized, and the question of how this bias might impact conclusions about human cognition in general BIBREF19 and category learning specifically is under active debate BIBREF9 . Although laboratory studies are invaluable for understanding categorization phenomena in a controlled environment, they are also expensive and time-consuming to conduct, and consequently problematic to scale.\nIn this work, we scale the investigation of category learning and representation along two axes: (1) the complexity of the learning environment, and consequently the richness of learnable concept and category representations, and (2) the diversity of languages and cultures considered in evaluation. We present a novel knowledge-lean, cognitively motivated Bayesian model which learns categories and their structured features jointly from large natural language text corpora in five diverse languages: Arabic, Chinese, English, French, and German. We approximate the learning environment using large corpora of natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Besides text corpora can cover arbitrarily semantically complex domains, and are available across languages, providing an ideal test environment for studying categorization at scale.\nFigure 1 illustrates example input to our model, and Figure 2 shows example categories and associated features as induced by our model from the English Wikipedia. Following prior work BIBREF21 , BIBREF22 , we create language-specific sets of stimuli, each consisting of a mention of target concept (e.g., apple), within its local linguistic context (e.g., {contains, seeds}; cf., Figure 1 ). We consider each stimulus an observation of the concept, i.e., the word referring to the concept is an instance of the concept itself, and its context words are a representation of its features. Our model infers categories as groups of concepts occurring with similar features; and it infers feature types as groups of features which co-occur with each other. The output of our model (cf., Figure 2 ) are categories as clusters of concepts, each associated with a set of feature types, i.e., thematically coherent groups of features. We train a separate model on each of our target languages, each time presenting the model with input stimuli from the relevant language.\nComputational models in general, and Bayesian models in particular, allow to investigate hypotheses about cognitive phenomena by systematically modifying the learning mechanism or available input while observing the learning outcome. Bayesian models have been applied to a variety of cognitive phenomena BIBREF23 , BIBREF24 , BIBREF25 , and category acquisition is no exception. Following from Anderson's BIBREF14 , BIBREF26 , BIBREF27 seminal work, a number of models have been developed, and tested in their ability to reproduce human behavior in laboratory settings by exposing the models to small sets of controlled inputs with restricted features. In this work we draw on the full potential of computational modeling by exposing our models to (a) more complex data reflecting the diversity of contexts in which concepts can be observed; and (b) a input data in different languages, shedding light on the applicability of computational cognitive models beyond the prevalent English test language.\nCategorization tasks in a laboratory environment typically involve stimuli with a small set of features which are relevant to the categorization target, eliminating the need to detect features, and discriminate them in their relevance. In the real world, however, concepts are observed in contexts and a substantial part of acquiring categorical knowledge involves learning which features are useful to discriminate among concepts. In fact, research has shown that humans learn features jointly with categories BIBREF28 , BIBREF29 and that these features are themselves structured so as to represent the diversity and complexity of the properties exhibited in the world BIBREF30 , BIBREF31 , BIBREF32 . Our novel model of category learning presented in this article, jointly learns categories and their structured features from large sets of informationally rich data.\nOur work exemplifies the opportunities that arise from computational models and large data sets for investigating the mechanisms with which conceptual representations emerge, as well as the representations themselves in a broader context. We simulate the acquisition of categories comprising hundreds of concepts by approximating the learning environment with natural language text. Language has been shown to redundantly encode much of the non-linguistic information in the natural environment BIBREF20 , as well as human-like biases BIBREF33 , and to influence the emergence of categories BIBREF4 , BIBREF5 . Text corpora are a prime example of naturally occurring large-scale data sets BIBREF34 , BIBREF35 , BIBREF36 . In analogy to real-world situations, they encapsulate rich, diverse, and potentially noisy, information. The wide availability of corpora allows us to train and evaluate cognitive models on data from diverse languages and cultures. We test our model on corpora from five languages, derived from the online encyclopedia Wikipedia in Arabic, Chinese, French, English, and German. Wikipedia is a valuable resource for our study because it (a) discusses concepts and their properties explicitly and can thus serve as a proxy for the environment speakers of a language are exposed to; and (b) allows us to construct corpora which are highly comparable in their content across languages, controlling for effects of genre or style.\nWe present a series of evaluations investigating the quality of the induced categories and features. Leveraging a reference comprising hundreds of concepts and more than 30 categories, we demonstrate that our model learns meaningful categories in all five target languages. We furthermore show, through crowd-sourced evaluations involving native speakers of each target language, that the induced feature types are (a) each thematically coherent and interpretable; and (b) are associated with categories in comprehensible ways. We discuss language-specific idiosyncrasies emerging from the induced representations.\nIn the remainder of this article, we first review related literature, before we present a cognitively motivated model for learning categories and their structured representations from large natural language corpora. We then evaluate the quality of the emerging representations, as well as the generalizability of our model across languages. Note that the primary goal of this work is not to characterize differences in categories and features arising from different languages (even though this would be an interesting avenue for future work). Rather, we aim to demonstrate the utility of large-scale naturalistic datasets for cognitive modeling, and to verify mechanisms of categorization known from laboratory studies at scale and across communities.\nBased on their reports, in this paper, we propose a neural language model that utilizes character n-gram embeddings. Our proposed method encodes character n-gram embeddings to a word embedding with simplified Multi-dimensional Self-attention (MS).",

        "evidence": "Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the mid-brain producing several motor and non-motor impairments in the patients BIBREF0. Motor symptoms include among others, bradykinesia, rigidity, resting tremor, micrographia, and different speech impairments. The speech impairments observed in PD patients are typically grouped as hypokinetic dysarthria, and include symptoms such as vocal folds rigidity, bradykinesia, and reduced control of muscles and limbs involved in the speech production. The effects of dysarthria in the speech of PD patients include increased acoustic noise, reduced intensity, harsh and breathy voice quality, increased voice nasality, monopitch, monoludness, speech rate disturbances, imprecise articulation of consonants BIBREF1, and involuntary introduction of pauses BIBREF2. Clinical observations in the speech of patients can be objectively and automatically measured by using computer aided methods supported in signal processing and pattern recognition with the aim to address two main aspects: (1) to support the diagnosis of the disease by classifying healthy control (HC) subjects and patients, and (2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.\nMost of the studies in the literature to classify PD from speech are based on computing hand-crafted features and using classifiers such as support vector machines (SVMs) or K-nearest neighbors (KNN). For instance, in BIBREF3, the authors computed features related to perturbations of the fundamental frequency and amplitude of the speech signal to classify utterances from 20 PD patients and 20 HC subjects, Turkish speakers. Classifiers based on KNN and SVMs were considered, and accuracies of up to 75% were reported. Later, in BIBREF4 the authors proposed a phonation analysis based on several time frequency representations to assess tremor in the speech of PD patients. The extracted features were based on energy and entropy computed from time frequency representations. Several classifiers were used, including Gaussian mixture models (GMMs) and SVMs. Accuracies of up to 77% were reported in utterances of the PC-GITA database BIBREF5, formed with utterances from 50 PD patients and 50 HC subjects, Colombian Spanish native speakers. The authors from BIBREF6 computed features to model different articulation deficits in PD such as vowel quality, coordination of laryngeal and supra-laryngeal activity, precision of consonant articulation, tongue movement, occlusion weakening, and speech timing. The authors studied the rapid repetition of the syllables /pa-ta-ka/ pronounced by 24 Czech native speakers, and reported an accuracy of 88% discriminating between PD patients and HC speakers, using an SVM classifier. Additional articulation features were proposed in BIBREF7, where the authors modeled the difficulty of PD patients to start/stop the vocal fold vibration in continuous speech. The model was based on the energy content in the transitions between unvoiced and voiced segments. The authors classified PD patients and HC speakers with speech recordings in three different languages (Spanish, German, and Czech), and reported accuracies ranging from 80% to 94% depending on the language; however, the results were optimistic, since the hyper-parameters of the classifier were optimized based on the accuracy on the test set. Another articulation model was proposed in BIBREF8. The authors considered a forced alignment strategy to segment the different phonetic units in the speech utterances. The phonemes were segmented and grouped to train different GMMs. The classification was performed based on a threshold of the difference between the posterior probabilities from the models created for HC subjects and PD patients. The model was tested with Colombian Spanish utterances from the PC-GITA database BIBREF5 and with the Czech data from BIBREF9. The authors reported accuracies of up to 81% for the Spanish data, and of up to 94% for the Czech data.\nIn addition to the hand-crafted feature extraction models, there is a growing interest in the research community to consider deep learning models in the assessment of the speech of PD patients BIBREF10, BIBREF11, BIBREF12. Deep learning methods have the potential to extract more abstract and robust features than those manually computed. These features could help to improve the accuracy of different models to classify pathological speech, such as PD BIBREF13. A deep learning based articulation model was proposed in BIBREF11 to model the difficulties of the patients to stop/start the vibration of the vocal folds. Transitions between voiced and unvoiced segments were modeled with time-frequency representations and convolutional neural networks (CNNs). The authors considered speech recordings of PD patients and HC speakers in three languages: Spanish, German, and Czech, and reported accuracies ranging from 70% to 89%, depending on the language. However, in a language independent scenario, i.e., training the CNN with utterances from one language and testing with the remaining two, the results were not satisfactory (accuracy$<60\\%$).\nThe classification of PD from speech in different languages has to be carefully conducted to avoid bias towards the linguistic content present in each language. For instance, Czech and German languages are richer than Spanish language in terms of consonant production, which may cause that it is easier to produce consonant sounds by Czech PD patients than by Spanish PD patients. Despite these language dependent issues, the results in the classification of PD in different languages could be improved using a transfer learning strategy among languages, i.e., to train a base model with utterances from one language, and then, to perform a fine-tuning of the weights with utterances from the target language BIBREF14. Similar approaches based on transfer learning have been recently considered to classify PD using handwriting BIBREF15. In the present study, we propose a methodology to classify PD via a transfer learning strategy with the aim to improve the accuracy in different languages. CNNs trained with utterances from one language are used to initialize a model to classify speech utterances from PD patients in a different language. The models are evaluated with speech utterances in Spanish, German, and Czech languages. The results suggest that the use of a transfer learning strategy improved the accuracy of the models over 8% with respect to those obtained when the model is trained only with utterance from the target language.\nClinical observations in the speech of patients can be objectively and automatically measured by using computer aided methods supported in signal processing and pattern recognition with the aim to address two main aspects: (1) to support the diagnosis of the disease by classifying healthy control (HC) subjects and patients, and (2) to predict the level of degradation of the speech of the patients according to a specific clinical scale.",

        "question": "How to define OFFENSIVE (OFF) in the data?",
        "answer": "OFFENSIVE (OFF): Offensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as: Direct threats or incitement.",
        "evidence": "We developed the annotation guidelines jointly with an experienced annotator, who is a native Arabic speaker with a good knowledge of various Arabic dialects. We made sure that our guidelines were compatible with those of OffensEval2019. The annotator carried out all annotation. Tweets were given one or more of the following four labels: offensive, vulgar, hate speech, or clean. Since the offensive label covers both vulgar and hate speech and vulgarity and hate speech are not mutually exclusive, a tweet can be just offensive or offensive and vulgar and/or hate speech. The annotation adhered to the following guidelines:\nOffensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as:\nDirect threats or incitement, ex: احرقوا> مقرات المعارضة> (“AHrqwA mqrAt AlmEArDp” – “burn the headquarters of the opposition”) and هذا المنافق يجب قتله> (“h*A AlmnAfq yjb qtlh” – “this hypocrite needs to be killed”).\nInsults and expressions of contempt, which include: Animal analogy, ex: يا كلب> (“yA klb” – “O dog”) and كل تبن> (“kl tbn” – “eat hay”).; Insult to family members, ex: يا روح أمك> (“yA rwH Amk” – “O mother's soul”); Sexually-related insults, ex: يا ديوث> (“yA dywv” – “O person without envy”); Damnation, ex: الله يلعنك> (“Allh ylEnk” – “may Allah/God curse you”); and Attacks on morals and ethics, ex: يا كاذب> (“yA kA*b” – “O liar”)\nVulgar tweets are a subset of offensive tweets and contain profanity, such as mentions of private parts or sexual-related acts or references.\nHate speech tweets, a subset of offensive tweets containing offensive language targeting group based on common characteristics such as: Race, ex: يا زنجي> (“yA znjy” – “O negro”); Ethnicity, ex. الفرس الأنجاس> (“Alfrs AlAnjAs” – “Impure Persians”); Group or party, ex: أبوك شيوعي> (“Abwk $ywEy” – “your father is communist”); and Religion, ex: دينك القذر> (“dynk Alq*r” – “your filthy religion”).\nClean tweets do not contain vulgar or offensive language. We noticed that some tweets have some offensive words, but the whole tweet should not be considered as offensive due to the intention of users. This suggests that normal string match without considering contexts will fail in some cases. Examples of such ambiguous cases include: Humor, ex: يا عدوة الفرحة ههه> (“yA Edwp AlfrHp hhh” – “O enemy of happiness hahaha”); Advice, ex: لا تقل لصاحبك يا خنزير> (“lA tql lSAHbk yA xnzyr” – “don't say to your friend: You are a pig”); Condition, ex: إذا عارضتهم يقولون يا عميل> (“A*A EArDthm yqwlwn yA Emyl” – “if you disagree with them they will say: You are an agent”); Condemnation, ex: لماذا نسب بقول: يا بقرة؟> (“lmA*A nsb bqwl: yA bqrp?” – “Why do we insult others by saying: O cow?”); Self offense, ex: تعبت من لساني القذر> (“tEbt mn lsAny Alq*r” – “I am tired of my dirty tongue”); Non-human target, ex: يا بنت المجنونة يا كورة> (“yA bnt Almjnwnp yA kwrp” – “O daughter of the crazy one O football”); and Quotation from a movies or a story, ex: تاني يا زكي! تاني يا فاشل> (“tAny yA zky! tAny yA fA$l” – “again O Zaky! again O loser”). For other ambiguous cases, the annotator searched Twitter to find how actual users used expressions.\nTable TABREF11 shows the distribution of the annotated tweets. There are 1,915 offensive tweets, including 225 vulgar tweet and 506 hate speech tweets, and 8,085 clean tweets. To validate the quality of annotation, a random sample of 100 tweets from the data, containing 50 offensive and 50 clean tweets, was given to additional three annotators. We calculated the Inter-Annotator Agreement between the annotators using Fleiss’s Kappa coefficient BIBREF23. The Kappa score was 0.92 indicating high quality annotation and agreement.\nOFFENSIVE (OFF): Offensive tweets contain explicit or implicit insults or attacks against other people, or inappropriate language, such as: Direct threats or incitement, ex: é “PAªÖÏ@ H@Q  ®Ó @ñ ¯Qk@ (“AHrqwA mqrAt AlmEArDp” – “burn opposition headquar_x0002_ters”) and \u0010 ‡ ¯A JÖÏ@ @ Yë @ñÊ\u0010 J \u0010 ¯@ (“h*A AlmnAfq yjb qtlh” – “kill this hypocrite”).",

        "question": "What model do they use in their method?",
        "answer": "A probabilistic version of the neural mention-ranking model.",
        "evidence": "Coreference resolution is the task of identifying all mentions which refer to the same entity in a document. It has been shown beneficial in many natural language processing (NLP) applications, including question answering BIBREF0 and information extraction BIBREF1 , and often regarded as a prerequisite to any text understanding task.\nCoreference resolution can be regarded as a clustering problem: each cluster corresponds to a single entity and consists of all its mentions in a given text. Consequently, it is natural to evaluate predicted clusters by comparing them with the ones annotated by human experts, and this is exactly what the standard metrics (e.g., MUC, B INLINEFORM0 , CEAF) do. In contrast, most state-of-the-art systems are optimized to make individual co-reference decisions, and such losses are only indirectly related to the metrics.\nOne way to deal with this challenge is to optimize directly the non-differentiable metrics using reinforcement learning (RL), for example, relying on the REINFORCE policy gradient algorithm BIBREF2 . However, this approach has not been very successful, which, as suggested by clark-manning:2016:EMNLP2016, is possibly due to the discrepancy between sampling decisions at training time and choosing the highest ranking ones at test time. A more successful alternative is using a `roll-out' stage to associate cost with possible decisions, as in clark-manning:2016:EMNLP2016, but it is computationally expensive. Imitation learning BIBREF3 , BIBREF4 , though also exploiting metrics, requires access to an expert policy, with exact policies not directly computable for the metrics of interest.\nIn this work, we aim at combining the best of both worlds by proposing a simple method that can turn popular coreference evaluation metrics into differentiable functions of model parameters. As we show, this function can be computed recursively using scores of individual local decisions, resulting in a simple and efficient estimation procedure. The key idea is to replace non-differentiable indicator functions (e.g. the member function INLINEFORM0 ) with the corresponding posterior probabilities ( INLINEFORM1 ) computed by the model. Consequently, non-differentiable functions used within the metrics (e.g. the set size function INLINEFORM2 ) become differentiable ( INLINEFORM3 ). Though we assume that the scores of the underlying statistical model can be used to define a probability model, we show that this is not a serious limitation. Specifically, as a baseline we use a probabilistic version of the neural mention-ranking model of P15-1137, which on its own outperforms the original one and achieves similar performance to its global version BIBREF5 . Importantly when we use the introduced differentiable relaxations in training, we observe a substantial gain in performance over our probabilistic baseline. Interestingly, the absolute improvement (+0.52) is higher than the one reported in clark-manning:2016:EMNLP2016 using RL (+0.05) and the one using reward rescaling (+0.37). This suggests that our method provides a viable alternative to using RL and reward rescaling.\nThe outline of our paper is as follows: we introduce our neural resolver baseline and the B INLINEFORM0 and LEA metrics in Section SECREF2 . Our method to turn a mention ranking resolver into an entity-centric resolver is presented in Section SECREF3 , and the proposed differentiable relaxations in Section SECREF4 . Section SECREF5 shows our experimental results.\nSpecifically, as a baseline we use a probabilistic version of the neural mention-ranking model of P15-1137, which on its own outperforms the original one and achieves similar performance to its global version.",

We identify facial presentation, emotion from facial expression, and demographic features from profile/posted images . Table TABREF21 illustrates facial presentation differences in both profile and posted images (media) for depressed and control users in INLINEFORM0 . With control class showing significantly higher in both profile and media (8%, 9% respectively) compared to that for the depressed class. In contrast with age and gender disclosure, vulnerable users are less likely to disclose their facial identity, possibly due to lack of confidence or fear of stigma.\nFacial Expression:\nFollowing BIBREF8 's approach, we adopt Ekman's model of six emotions: anger, disgust, fear, joy, sadness and surprise, and use the Face++ API to automatically capture them from the shared images. Positive emotions are joy and surprise, and negative emotions are anger, disgust, fear, and sadness. In general, for each user u in INLINEFORM0 , we process profile/shared images for both the depressed and the control groups with at least one face from the shared images (Table TABREF23 ). For the photos that contain multiple faces, we measure the average emotion.\nGeneral Image Features:\nThe importance of interpretable computational aesthetic features for studying users' online behavior has been highlighted by several efforts BIBREF55 , BIBREF8 , BIBREF57 . Color, as a pillar of the human vision system, has a strong association with conceptual ideas like emotion BIBREF58 , BIBREF59 . We measured the normalized red, green, blue and the mean of original colors, and brightness and contrast relative to variations of luminance. We represent images in Hue-Saturation-Value color space that seems intuitive for humans, and measure mean and variance for saturation and hue. Saturation is defined as the difference in the intensities of the different light wavelengths that compose the color. Although hue is not interpretable, high saturation indicates vividness and chromatic purity which are more appealing to the human eye BIBREF8 . Colorfulness is measured as a difference against gray background BIBREF60 . Naturalness is a measure of the degree of correspondence between images and the human perception of reality BIBREF60 . In color reproduction, naturalness is measured from the mental recollection of the colors of familiar objects. Additionally, there is a tendency among vulnerable users to share sentimental quotes bearing negative emotions. We performed optical character recognition (OCR) with python-tesseract to extract text and their sentiment score. As illustrated in Table TABREF26 , vulnerable users tend to use less colorful (higher grayscale) profile as well as shared images to convey their negative feelings, and share images that are less natural (Figure FIGREF15 ). With respect to the aesthetic quality of images (saturation, brightness, and hue), depressed users use images that are less appealing to the human eye. We employ independent t-test, while adopting Bonferroni Correction as a conservative approach to adjust the confidence intervals.

        "evidence": "In this work, we address an open challenge in Offline RL. In the resource-constrained setting that is motivated by real world applications, the features available during training offline may be different than the limited features available online during deployment. We highlighted a performance gap between offline RL agents trained using only the online features and agents trained using all the offline features. To bridge this gap, we proposed a student-teacher-based policy transfer learning approach. The proposed algorithm improves over the baseline significantly even when the dataset quality is lacking in the resource-constrained setting. The simplicity of the approach (with just one additional hyperparameter) makes it easy to extend it to other offline RL algorithms. It would be interesting to study other transfer learning approaches (e.g., policy transfer with other divergence regularizations for stochastic policies) in the future. Moreover, we observe that the proposed approach benefits especially when the dataset quality is low which is often the case with real world datasets. Despite this, the performance gap with the teacher is still high (in the low quality data regime) and this suggests more tailored approaches are required.\nIn this work, we address an open challenge in Offline RL.

        "question": "What's the advantage of  CNN?",
        "answer": "CNN can automatically extract key features from the training data and does not need the hand-crafted features used in traditional supervised classifiers.",
        "evidence": "CNN can automatically extract key features from the training data. It grasps contextual local features from a sentence and, after several convolution operations, it forms a global feature vector out of those local features. CNN does not need the hand-crafted features used in traditional supervised classifiers. Such hand-crafted features are difficult to compute and a good guess for encoding the features is always necessary in order to get satisfactory results. CNN, instead, uses a hierarchy of local features which are important to learn context. The hand-crafted features often ignore such a hierarchy of local features.\nFeatures extracted by CNN can therefore be used instead of hand-crafted features, as they carry more useful information. The idea behind convolution is to take the dot product of a vector of INLINEFORM0 weights INLINEFORM1 also known as kernel vector with each INLINEFORM2 -gram in the sentence INLINEFORM3 to obtain another sequence of features INLINEFORM4 . DISPLAYFORM0 \nThus, a max pooling operation is applied over the feature map and the maximum value INLINEFORM0 is taken as the feature corresponding to this particular kernel vector. Similarly, varying kernel vectors and window sizes are used to obtain multiple features BIBREF32 . For each word INLINEFORM1 in the vocabulary, a INLINEFORM2 -dimensional vector representation is given in a look up table that is learned from the data BIBREF33 . The vector representation of a sentence, hence, is a concatenation of vectors for individual words. Similarly, we can have look up tables for other features. One might want to provide features other than words if these features are suspected to be helpful. The convolution kernels are then applied to word vectors instead of individual words.\nWe use these features to train higher layers of the CNN, in order to represent bigger groups of words in sentences. We denote the feature learned at hidden neuron INLINEFORM0 in layer INLINEFORM1 as INLINEFORM2 . Multiple features may be learned in parallel in the same CNN layer. The features learned in each layer are used to train the next layer: DISPLAYFORM0 \nwhere * indicates convolution and INLINEFORM0 is a weight kernel for hidden neuron INLINEFORM1 and INLINEFORM2 is the total number of hidden neurons. The CNN sentence model preserves the order of words by adopting convolution kernels of gradually increasing sizes that span an increasing number of words and ultimately the entire sentence. As mentioned above, each word in a sentence is represented using word embeddings.\nWe employ the publicly available word2vec vectors, which were trained on 100 billion words from Google News. The vectors are of dimensionality 300, trained using the continuous bag-of-words architecture BIBREF33 . Words not present in the set of pre-trained words are initialized randomly. However, while training the neural network, we use non-static representations. These include the word vectors, taken as input, into the list of parameters to be learned during training.\nTwo primary reasons motivated us to use non-static channels as opposed to static ones. Firstly, the common presence of informal language and words in tweets resulted in a relatively high random initialization of word vectors due to the unavailability of these words in the word2vec dictionary. Secondly, sarcastic sentences are known to include polarity shifts in sentimental and emotional degrees. For example, “I love the pain present in breakups\" is a sarcastic sentence with a significant change in sentimental polarity. As word2vec was not trained to incorporate these nuances, we allow our models to update the embeddings during training in order to include them. Each sentence is wrapped to a window of INLINEFORM0 , where INLINEFORM1 is the maximum number of words amongst all sentences in the dataset. We use the output of the fully-connected layer of the network as our feature vector.\nWe have done two kinds of experiments: firstly, we used CNN for the classification; secondly, we extracted features from the fully-connected layer of the CNN and fed them to an SVM for the final classification. The latter CNN-SVM scheme is quite useful for text classification as shown by Poria et al. BIBREF18 . We carry out n-fold cross-validation on the dataset using CNN. In every fold iteration, in order to obtain the training and test features, the output of the fully-connected layer is treated as features to be used for the final classification using SVM. Table TABREF12 shows the training settings for each CNN model developed in this work. ReLU is used as the non-linear activation function of the network. The network configurations of all models developed in this work are given in Table TABREF12 .\nCNN can automatically extract key features from the training data.

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation.

        "question": "What framework do the authors use?",
        "answer": "Variational Bayesian inference based acoustic unit discovery (AUD) framework.",
        "evidence": "Topic identification (topic ID) on speech aims to identify the topic(s) for given speech recordings, referred to as spoken documents, where the topics are a predefined set of classes or labels. This task is typically formulated as a three-step process. First, speech is tokenized into words or phones by automatic speech recognition (ASR) systems BIBREF0 , or by limited-vocabulary keyword spotting BIBREF1 . Second, standard text-based processing techniques are applied to the resulting tokenizations, and produce a vector representation for each spoken document, typically a bag-of-words multinomial representation, or a more compact vector given by probabilistic topic models BIBREF2 , BIBREF3 . Finally, topic ID is performed on the spoken document representations by supervised training of classifiers, such as Bayesian classifiers and support vector machines (SVMs).\nHowever, in the first step, training the ASR system required for tokenization itself requires transcribed speech and pronunciations. In this paper, we focus on a difficult and realistic scenario where the speech corpus of a test language is annotated only with a minimal number of topic labels, i.e., no manual transcriptions or dictionaries for building an ASR system are available. We aim to exploit approaches that enable topic ID on speech without any knowledge of that language other than the topic annotations.\nIn this scenario, while previous work demonstrates that the cross-lingual phoneme recognizers can produce reasonable speech tokenizations BIBREF4 , BIBREF5 , the performance is highly dependent on the language and environmental condition (channel, noise, etc.) mismatch between the training and test data. Therefore, we focus on unsupervised approaches that operate directly on the speech of interest. Raw acoustic feature-based unsupervised term discovery (UTD) is one such approach that aims to identify and cluster repeating word-like units across speech based around segmental dynamic time warping (DTW) BIBREF6 , BIBREF7 . BIBREF8 shows that using the word-like units from UTD for spoken document classification can work well; however, the results in BIBREF8 are limited since the acoustic features on which UTD is performed are produced by acoustic models trained from the transcribed speech of its evaluation corpus. In this paper, we investigate UTD-based topic ID performance when UTD operates on language-independent speech representations extracted from multilingual bottleneck networks trained on languages other than the test language BIBREF9 . Another alternative to producing speech tokenizations without language dependency is the model-based approach, i.e., unsupervised learning of hidden Markov model (HMM) based phoneme-like units from untranscribed speech. We exploit the Variational Bayesian inference based acoustic unit discovery (AUD) framework in BIBREF10 that allows parallelized large-scale training. In topic ID tasks, such AUD-based systems have been shown to outperform other systems based on cross-lingual phoneme recognizers BIBREF5 , and this paper aims to further investigate how the performance compares among UTD, AUD and ASR based systems.\nMoreover, after the speech is tokenized, these works BIBREF0 , BIBREF1 , BIBREF4 , BIBREF5 , BIBREF8 , BIBREF9 are limited to using bag-of-words features as spoken document representations. While UTD only identifies relatively long (0.5 – 1 sec) repeated terms, AUD/ASR enables full-coverage segmentation of continuous speech into a sequence of units/words, and such a resulting temporal sequence enables another feature learning architecture based on convolutional neural networks (CNNs) BIBREF11 ; instead of treating the sequential tokens as a bag of acoustic units or words, the whole token sequence is encoded as concatenated continuous vectors, and followed by convolution and temporal pooling operations that capture the local and global dependencies. Such continuous space feature extraction frameworks have been used in various language processing tasks like spoken language understanding BIBREF12 , BIBREF13 and text classification BIBREF14 , BIBREF15 . However, three questions are worth investigating in our AUD-based setting: (i) if such a CNN-based framework can perform as well on noisy automatically discovered phoneme-like units as on orthographic words/characters, (ii) if pre-trained vectors of phoneme-like units from word2vec BIBREF16 provide superior performance to random initialization as evidenced by the word-based tasks, and (iii) if CNNs are still competitive in low-resource settings of hundreds to two-thousand training exemplars, rather than the large/medium sized datasets as in previous work BIBREF14 , BIBREF15 .\nFinally, incorporating the different tokenization and feature representation approaches noted above, we perform comprehensive topic ID evaluations on both single-label and multi-label spoken document classification tasks.\n\nWe exploit the Variational Bayesian inference based acoustic unit discovery (AUD) framework in that allows parallelized large-scale training.",

It is used to identify and categorise opinions expressed by reviewers on a topic or an entity. Sentiment analysis can be leveraged in marketing, social media analysis, and customer service. Although many studies have been conducted for sentiment analysis in widely spoken languages, this topic is still immature for Turkish and many other languages.\nNeural networks outperform the conventional machine learning algorithms in most classification tasks, including sentiment analysis BIBREF0. In these networks, word embedding vectors are fed as input to overcome the data sparsity problem and make the representations of words more “meaningful” and robust. Those embeddings indicate how close the words are to each other in the vector space model (VSM).\nMost of the studies utilise embeddings, such as word2vec BIBREF1, which take into account the syntactic and semantic representations of the words only. Discarding the sentimental aspects of words may lead to words of different polarities being close to each other in the VSM, if they share similar semantic and syntactic features.\nFor Turkish, there are only a few studies which leverage sentimental information in generating the word and document embeddings. Unlike the studies conducted for English and other widely-spoken languages, in this paper, we use the official dictionaries for this language and combine the unsupervised and supervised scores to generate a unified score for each dimension of the word embeddings in this task.\nOur main contribution is to create original and effective word vectors that capture syntactic, semantic, and sentimental characteristics of words, and use all of this knowledge in generating embeddings. We also utilise the word2vec embeddings trained on a large corpus. Besides using these word embeddings, we also generate hand-crafted features on a review basis and create document vectors. We evaluate those embeddings on two datasets. The results show that we outperform the approaches which do not take into account the sentimental information.

For instance, an open IE-powered medical question answering (QA) system may require its assertions in higher precision (and consequently lower recall) than QA systems for other domains. For supervised open IE systems, the confidence score of an assertion is typically computed based on its extraction likelihood given by the model BIBREF3 , BIBREF5 . However, we observe that this often yields sub-optimal ranking results, with incorrect extractions of one sentence having higher likelihood than correct extractions of another sentence. We hypothesize this is due to the issue of a disconnect between training and test-time objectives. Specifically, the system is trained solely to raise likelihood of gold-standard extractions, and during training the model is not aware of its test-time behavior of ranking a set of system-generated assertions across sentences that potentially include incorrect extractions.\nWe follow the evaluation metrics described by Stanovsky:2016:OIE2016: area under the precision-recall curve (AUC) and F1 score.

        "answer": "There are many traits that great baseball and softball batters share.  Some of the most important are extreme confidence, sound batting mechanics, and coordination developed though a combination of talent and practice.  \n\nAll great hitters share some consistencies in their batting mechanics such as their lower half mechanics, their hand and bat path, and their head and eye movement.\n\nWith their lower half mechanics they generate powerful torque from the ground up by timing the planting their feet in a balanced position and forcefully rotating and opening their hips.  Hitting powerful line drives relies heavily on the barrel of the bat meeting the ball flush.  Batters increase the odds of this by keeping their hands in, connected to the back shoulder, and having one palm facing up and one palm facing down for as long as possible as the bat path travels through the strike zone.  Finally, all great hitters maintain consistent head and eye position throughout the motion. \n\nThere are many nuances of batting mechanics that all great hitters share but these are some of the most important.",

        "question": "What is the key challenge in cyberbullying research?",
        "answer": "The key challenge is the availability of suitable data.",
        "evidence": "As mentioned earlier, although research on cyberbullying detection is more limited than social studies on the phenomenon, some important advances have been made in recent years. In what follows, we present a brief overview of the most important natural language processing approaches to cyberbullying detection.\nAlthough some studies have investigated the effectiveness of rule-based modelling BIBREF31 , the dominant approach to cyberbullying detection involves machine learning. Most machine learning approaches are based on supervised BIBREF32 , BIBREF33 , BIBREF34 or semi-supervised learning BIBREF35 . The former involves the construction of a classifier based on labeled training data, whereas semi-supervised approaches rely on classifiers that are built from a training corpus containing a small set of labeled and a large set of unlabelled instances (a method that is often used to handle data sparsity). As cyberbullying detection essentially involves the distinction between bullying and non-bullying posts, the problem is generally approached as a binary classification task where the positive class is represented by instances containing (textual) cyberbullying, while the negative class includes instances containing non-cyberbullying or `innocent' text.\nA key challenge in cyberbullying research is the availability of suitable data, which is necessary to develop models that characterise cyberbullying. In recent years, only a few datasets have become publicly available for this particular task, such as the training sets provided in the context of the CAW 2.0 workshop and more recently, the Twitter Bullying Traces dataset BIBREF36 . As a result, several studies have worked with the former or have constructed their own corpus from social media websites that are prone to bullying content, such as YouTube BIBREF32 , BIBREF33 , Formspring BIBREF33 , and ASKfm BIBREF37 (the latter two are social networking sites where users can send each other questions or respond to them). Despite the bottleneck of data availability, existing approaches to cyberbullying detection have shown its potential, and the relevance of automatic text analysis techniques to ensure child safety online has been recognised BIBREF38 , BIBREF39 .\nAmong the first studies on cyberbullying detection are BIBREF34 , BIBREF31 , BIBREF33 , who explored the predictive power of INLINEFORM0 -grams (with and without tf-idf weighting), part-of-speech information (e.g. first and second pronouns), and sentiment information based on profanity lexicons for this task. Similar features were also exploited for the detection of cyberbullying events and fine-grained text categories related to cyberbullying BIBREF37 , BIBREF40 . More recent studies have demonstrated the added value of combining such content-based features with user-based information, such as including users' activities on a social network (i.e., the number of posts), their age, gender, location, number of friends and followers, and so on BIBREF32 , BIBREF35 , BIBREF41 . Moreover, semantic features have been explored to further improve classification performance of the task. To this end, topic model information BIBREF42 , as well as semantic relations between INLINEFORM1 -grams (according to a Word2Vec model BIBREF43 ) have been integrated.\nAs mentioned earlier, data collection remains a bottleneck in cyberbullying research. Although cyberbullying has been recognised as a serious problem (cf. Section SECREF1 ), real-world examples are often hard to find in public platforms. Naturally, the vast majority of communications do not contain traces of verbal aggression or transgressive behaviour. When constructing a corpus for machine learning purposes, this results in imbalanced datasets, meaning that one class (e.g. cyberbullying posts) is much less represented in the corpus than the other (e.g. non-cyberbullying posts). To tackle this problem, several studies have adopted resampling techniques BIBREF35 , BIBREF41 , BIBREF31 that create synthetic minority class examples or reduce the number of negative class examples (i.e., minority class oversampling and majority class undersampling BIBREF44 ).\nTable TABREF9 presents a number of recent studies on cyberbullying detection, providing insight into the state of the art in cyberbullying research and the contribution of the current research to the domain.\nThe studies discussed in this section have demonstrated the feasibility of automatic cyberbullying detection in social media data by making use of a varied set of features. Most of them have, however, focussed on cyberbullying `attacks', or posts written by a bully. Moreover, it is not entirely clear if different forms of cyberbullying have been taken into account (e.g. sexual intimidation or harassment, or psychological threats), in addition to derogatory language or insults.\nIn the research described in this paper, cyberbullying is considered a complex phenomenon consisting of different forms of harmful behaviour online, which are described in more detail in our annotation scheme BIBREF30 . Purposing to facilitate manual monitoring efforts on social networks, we develop a system that automatically detects signals of cyberbullying, including attacks from bullies, as well as victim and bystander reactions. Similarly, BIBREF42 investigated bullying traces posted by different author roles (accuser, bully, reporter, victim). However, they collected tweets by using specific keywords (i.e., bully, bullied and bullying). As a result, their corpus contains many reports or testimonials of a cyberbullying incident (example 1), instead of actual signals that cyberbullying is going on. Moreover, their method implies that cyberbullying-related content devoid of such keywords will not be part of the training corpus.\n`Some tweens got violent on the n train, the one boy got off after blows 2 the chest... Saw him cryin as he walkd away :( bullying not cool' BIBREF42 \nFor this research, English and Dutch social media data were annotated for different forms of cyberbullying, based on the actors involved in a cyberbullying incident. After preliminary experiments for Dutch BIBREF37 , BIBREF40 , we currently explore the viability of detecting cyberbullying-related posts in Dutch and English social media. To this end, binary classification experiments are performed exploiting a rich feature set and optimised hyperparameters.\nfont=footnotesize,sc,justification=centering,labelsep=period\nA key challenge in cyberbullying research is the availability of suitable data, which is necessary to develop models that characterise cyberbullying.",

        "evidence": "Electroencephalography (EEG) recordings of brain activity taken while participants read or listen to language are widely used within the cognitive neuroscience and psycholinguistics communities as a tool to study language comprehension. Several time-locked stereotyped EEG responses to word-presentations -- known collectively as event-related potentials (ERPs) -- are thought to be markers for semantic or syntactic processes that take place during comprehension. However, the characterization of each individual ERP in terms of what features of a stream of language trigger the response remains controversial. Improving this characterization would make ERPs a more useful tool for studying language comprehension. We take a step towards better understanding the ERPs by fine-tuning a language model to predict them. This new approach to analysis shows for the first time that all of the ERPs are predictable from embeddings of a stream of language. Prior work has only found two of the ERPs to be predictable. In addition to this analysis, we examine which ERPs benefit from sharing parameters during joint training. We find that two pairs of ERPs previously identified in the literature as being related to each other benefit from joint training, while several other pairs of ERPs that benefit from joint training are suggestive of potential relationships. Extensions of this analysis that further examine what kinds of information in the model embeddings relate to each ERP have the potential to elucidate the processes involved in human language comprehension.\nHowever, the characterization of each individual ERP in terms of what features of a stream of language trigger the response remains controversial.

And my dreams came true, first the flight school, then a military pilot, but everything made sense after my former instructor at the academy offered me a spot in the NASA Astronaut program. I couldn't believe it. I'm going to space? Really? \n\nA few hard years later I was a regular member of a mission flying back and forth between Earth and ISS. Sitting down on top of a rocket strapped down inside of a tiny capsule is not fun, I can tell you that, but the rush of adrenaline when you're stuck to your seat flying through the atmosphere never gets old.\n\nBut this time, the feeling was - different. I arrived at the ISS on schedule and relieved my colleague Max. She was happy to see me, after all, 6 months spinning around the globe alone would do that to you. She was a dear friend of mine, but we didn't have much time for catchup and pleasantries.

More land, more resources, more money. \n\nThey launched their missiles first. At least it seemed that way from the media that was still running at the time. Didn't matter though, our defenses were inadequate. Watching through my tiny window I could see the planet burning. We, of course, fired back. I could see flash after flash hitting the ground.

The precise function of palmitoylation depends on the particular protein being considered. Palmitoylation enhances the hydrophobicity of proteins and contributes to their membrane association. Palmitoylation also appears to play a significant role in subcellular trafficking of proteins between membrane compartments, as well as in modulating protein–protein interactions. In contrast to prenylation and myristoylation, palmitoylation is usually reversible (because the bond between palmitic acid and protein is often a thioester bond). The reverse reaction in mammalian cells is catalyzed by acyl-protein thioesterases (APTs) in the cytosol and palmitoyl protein thioesterases in lysosomes. Because palmitoylation is a dynamic, post-translational process, it is believed to be employed by the cell to alter the subcellular localization, protein–protein interactions, or binding capacities of a protein.\n\nAn example of a protein that undergoes palmitoylation is hemagglutinin, a membrane glycoprotein used by influenza to attach to host cell receptors. The palmitoylation cycles of a wide array of enzymes have been characterized in the past few years, including H-Ras, Gsα, the β2-adrenergic receptor, and endothelial nitric oxide synthase (eNOS). In signal transduction via G protein, palmitoylation of the α subunit, prenylation of the γ subunit, and myristoylation is involved in tethering the G protein to the inner surface of the plasma membrane so that the G protein can interact with its receptor.",

While morphology is a basic task in lexical analysis of English, word segmentation is considered a basic task in lexical analysis of Vietnamese and other East Asian languages processing. This task is to determine borders between words in a sentence. In other words, it is segmenting a list of tokens into a list of words such that words are meaningful.\nWord segmentation is the primary step in prior to other natural language processing tasks i. e., term extraction and linguistic analysis (as shown in Figure 1). It identifies the basic meaningful units in input texts which will be processed in the next steps of several applications. For named entity recognization BIBREF2 , word segmentation chunks sentences in input documents into sequences of words before they are further classified in to named entity classes. For Vietnamese language, words and candidate terms can be extracted from Vietnamese copora (such as books, novels, news, and so on) by using a word segmentation tool. Conformed features and context of these words and terms are used to identify named entity tags, topic of documents, or function words. For linguistic analysis, several linguistic features from dictionaries can be used either to annotating POS tags or to identifying the answer sentences. Moreover, language models can be trained by using machine learning approaches and be used in tagging systems, like the named entity recognization system of Tran et al.

Approaches for word segmentation task are variety, from lexicon-based to machine learning-based methods. Recently, machine learning-based methods are used widely to solve this issue, such as: Support Vector Machine or Conditional Random Fields BIBREF7 , BIBREF8 . In general, Chinese is a language which has the most studies on the word segmentation issue. However, there is a lack of survey of word segmentation studies on Asian languages and Vietnamese as well. This paper aims reviewing state-of-the-art word segmentation approaches and systems applying for Vietnamese. This study will be a foundation for studies on Vietnamese word segmentation and other following Vietnamese tasks as well, such as part-of-speech tagger, chunker, or parser systems.\nThere are several studies about the Vietnamese word segmentation task over the last decade. Dinh et al. started this task with Weighted Finite State Transducer (WFST) approach and Neural Network approach BIBREF9 . In addition, machine learning approaches are studied and widely applied to natural language processing and word segmentation as well. In fact, several studies used support vector machines (SVM) and conditional random fields (CRF) for the word segmentation task BIBREF7 , BIBREF8 . Based on annotated corpora and token-based features, studies used machine learning approaches to build word segmentation systems with accuracy about 94%-97%.\nAccording to our observation, we found that is lacks of complete review approaches, datasets and toolkits which we recently used in Vietnamese word segmentation. A all sided review of word segmentation will help next studies on Vietnamese natural language processing tasks have an up-to-date guideline and choose the most suitable solution for the task. The remaining part of the paper is organized as follows. Section II discusses building corpus in Vietnamese, containing linguistic issues and the building progress. Section III briefly mentions methods to model sentences and text in machine learning systems. Next, learning models and approaches for labeling and segmenting sequence data will be presented in Section IV. Section V mainly addresses two existing toolkits, vnTokenizer and JVnSegmenter, for Vietnamese word segmentation. Several experiments based on mentioned approaches and toolkits are described in Section VI. Finally, conclusions and future works are given in Section VII.\nThis paper aims reviewing state-of-the-art word segmentation approaches and systems applying for Vietnamese.",

        "question": "Who put forth the idea of machine translation in modern times?",
        "answer": "In modern times, the idea of machine translation was put forth by the philosopher and logician Yehoshua Bar-Hillel.",
        "evidence": "In this paper, we are exploring the historical significance of Croatian machine translation research group. The group was active in 1950s, and it was conducted by Bulcsu Laszlo, Croatian linguist, who was a pioneer in machine translation during the 1950s in Yugoslavia.\nTo put the research of the Croatian group in the right context, we have to explore the origin of the idea of machine translation. The idea of machine translation is an old one, and its origin is commonly connected with the work of Rene Descartes, i.e. to his idea of universal language, as described in his letter to Mersenne from 20.xi.1629 BIBREF0. Descartes describes universal language as a simplified version of the language which will serve as an “interlanguage” for translation. That is, if we want to translate from English to Croatian, we will firstly translate from English to an “interlanguage”, and then from the “interlanguage” to Croatian. As described later in this paper, this idea had been implemented in the machine translation process, firstly in the Indonesian-to-Russian machine translation system created by Andreev, Kulagina and Melchuk from the early 1960s.\nIn modern times, the idea of machine translation was put forth by the philosopher and logician Yehoshua Bar-Hillel (most notably in BIBREF1 and BIBREF2), whose papers were studied by the Croatian group. Perhaps the most important unrealized point of contact between machine translation and cybernetics happened in the winter of 1950/51. In that period, Bar-Hillel met Rudolf Carnap in Chicago, who introduced to him the (new) idea of cybernetics. Also, Carnap gave him the contact details of his former teaching assistant, Walter Pitts, who was at that moment with Norbert Wiener at MIT and who was supposed to introduce him to Wiener, but the meeting never took place BIBREF3. Nevertheless, Bar-Hillel was to stay at MIT where he, inspired by cybernetics, would go to organize the first machine translation conference in the world in 1952 BIBREF3.\nThe idea of machine translation was a tempting idea in the 1950s. The main military interest in machine translation as an intelligence gathering tool (translation of scientific papers, daily press, technical reports, and everything the intelligence services could get their hands on) was sparked by the Soviet advance in nuclear technology, and would later be compounded by the success of Vostok 1 (termed by the USA as a “strategic surprise”). In the nuclear age, being able to read and understand what the other side was working on was of crucial importance BIBREF4. Machine translation was quickly absorbed in the program of the Dartmouth Summer Research Project on Artificial Intelligence in 1956 (where Artificial Intelligence as a field was born), as one of the five core fields of artificial intelligence (later to be known as natural language processing). One other field was included here, the “nerve nets” as they were known back then, today commonly known as artificial neural networks. What is also essential for our discussion is that the earliest programming language for artificial intelligence, Lisp, was invented in 1958 by John McCarthy BIBREF5. But let us take a closer look at the history of machine translation. In the USA, the first major wave of government and military funding for machine translation came in 1954, and the period of abundancy lasted until 1964, when the National Research Council established the Automatic Language Processing Advisory Committee (ALPAC), which was to assess the results of the ten years of intense funding. The findings were very negative, and funding was almost gone BIBREF4, hence the ALPAC report became the catalyst for the first “AI Winter”.\nOne of the first recorded attempts of producing a machine translation system in the USSR was in 1954 BIBREF6, and the attempt was applauded by the Communist party of the Soviet Union, by the USSR Committee for Science and Technology and the USSR Academy of Sciences. The source does not specify how this first system worked, but it does delineate that the major figures of machine translation of the time were N. Andreev of the Leningrad State University, O. Kulagina and I. Melchuk of the Steklov Mathematical Institute. There is information on an Indonesian-to-Russian machine translation system by Andreev, Kulagina and Melchuk from the early 1960s, but it is reported that the system was ultimately a failure, in the same way early USA systems were. The system had statistical elements set forth by Andreev, but the bulk was logical and knowledge-heavy processing put forth by Kulagina and Melchuk. The idea was to have a logical intermediate language, under the working name “Interlingua”, which was the connector of both natural languages, and was used to model common-sense human knowledge. For more details, see BIBREF6.\nIn the USSR, there were four major approaches to machine translation in the late 1950s BIBREF7. The first one was the research at the Institute for Precise Mechanics and Computational Technology of the USSR Academy of Sciences. Their approach was mostly experimental and not much different from today's empirical methods. They evaluated the majority of algorithms known at the time algorithms over meticulously prepared datasets, whose main strength was data cleaning, and by 1959 they have built a German-Russian machine translation prototype. The second approach, as noted by Mulić BIBREF7, was championed by the team at the Steklov Mathematical Institute of the USSR Academy of Sciences led by A. A. Reformatsky. Their approach was mainly logical, and they extended the theoretical ideas of Bar-Hillel BIBREF2 to build three algorithms: French-Russian, English-Russian and Hungarian-Russian. The third and perhaps the most successful approach was the one by A. A. Lyapunov, O. S. Kulagina and R. L. Dobrushin. Their efforts resulted in the formation of the Mathematical Linguistics Seminar at the Faculty of Philology in Moscow in 1956 and in Leningrad in 1957. Their approach was mainly information-theoretic (but they also tried logic-based approaches BIBREF7), which was considered cybernetic at that time. This was the main role model for the Croatian efforts from 1957 onwards. The fourth, and perhaps most influential, was the approach at the Experimental Laboratory of the Leningrad University championed by N. D. Andreev BIBREF7. Here, the algorithms for Indonesian-Russian, Arabic-Russian, Hindu-Russian, Japanese-Russian, Burmese-Russian, Norwegian-Russian, English-Russian, Spanish-Russian and Turkish-Russian were being built. The main approach of Andreev's group was to use an intermediary language, which would capture the meanings BIBREF7. It was an approach similar to KL-ONE, which would be introduced in the West much later (in 1985) by Brachman and Schmolze BIBREF8. It is also interesting to note that the Andreev group had a profound influence on the Czechoslovakian machine translation program BIBREF9, which unfortunately suffered a similar fate as the Yugoslav one due to the lack of funding.\nAndreev's approach was in a sense \"external\". The modelling would be statistical, but its purpose would not be to mimic the stochasticity of the human thought process, but rather to produce a working machine translation system. Kulagina and Melchuk disagreed with this approach as they thought that more of what is presently called \"philosophical logic\" was needed to model the human thought process at the symbolic level, and according to them, the formalization of the human thought process was a prerequisite for developing a machine translation system (cf. BIBREF6). We could speculate that sub-symbolic processing would have been acceptable too, since that approach is also rooted in philosophical logic as a way of formalizing human cognitive functions and is also \"internal\" in the same sense symbolic approaches are.\nThere were many other centers for research in machine translation: Gorkovsky University (Omsk), 1st Moscow Institute for Foreign Languages, Computing Centre of the Armenian SSR and at the Institute for Automatics and Telemechanics of the Georgian SSR BIBREF7. It is worthwhile to note that both the USA and the USSR had access to state-of-the-art computers, and the political support for the production of such systems meant that computers were made available to researchers in machine translation. However, the results were poor in the late 1950s, and a working system was yet to be shown. All work was therefore theoretical work implemented on a computer, which proved to be sub-optimal.\nIn modern times, the idea of machine translation was put forth by the philosopher and logician Yehoshua Bar-Hillel (most notably in [3] and [4]), whose papers were studied by the Croatian group.",

We use an 1024-cell GRU layer and 1000-dimensional embeddings with dropout at every layer with the probability of 0.2 in the embedding and hidden layers and 0.1 in the input and ourput layers. We trained our systems using gradient descent optimization with Adadelta BIBREF13 on minibatches of size 80 and the gradient is rescaled whenever its norm exceed 1.0. All the trainings last approximately seven days if the early-stopping condition could not be reached. At a certain time, an external evaluation script on BLEU BIBREF14 is conducted on a development set to decide the early-stopping condition. This evaluation script has also being used to choose the model archiving the best BLEU on the development set instead of the maximal loglikelihood between the translations and target sentences while training.

        "evidence": "Yet surprisingly little is known about the agenda-setting process for international development in global governance institutions. This is perhaps best demonstrated by the lack of information on how the different goals and targets of the MDGs were decided, which led to much criticism and concern about the global governance of development BIBREF1 . More generally, we know little about the types of development issues that different countries prioritise, or whether country-specific factors such as wealth or democracy make countries more likely to push for specific development issues to be put on the global political agenda.\nThe analysis of discussion of international development in annual UN General Debate statements therefore uncovers two principle development topics: economic development and sustainable development. We find that discussion of Topic 2 is not significantly impacted by country-specific factors, such as wealth, population, democracy, levels of ODA, and conflict (although there are regional effects). However, we find that the extent to which countries discuss sustainable development (Topic 7) in their annual GD statements varies considerably according to these different structural factors. The results suggest that broadly-speaking we do not observe linear trends in the relationship between these country-specific factors and discussion of Topic 7. Instead, we find that there are significant fluctuations in the relationship between factors such as wealth, democracy, etc., and the extent to which these states discuss sustainable development in their GD statements.

        "evidence": "Humans have occupied the region since the last ice age 10,000 years ago. Fremont people and Ancestral Puebloans lived in the area until about 700 years ago. Spanish missionaries encountered Ute and Paiute tribes in the area when they first came through in 1775, but the first European-Americans to attempt settlement in the area were the Mormon Elk Mountain Mission in 1855, who soon abandoned the area. Ranchers, farmers, and prospectors later settled Moab in the neighboring Riverine Valley in the late 1870s. Word of the beauty of the surrounding rock formations spread beyond the settlement as a possible tourist destination.\n\nThe Arches area was first brought to the attention of the National Park Service by Frank A. Wadleigh, passenger traffic manager of the Denver and Rio Grande Western Railroad. Wadleigh, accompanied by railroad photographer George L. Beam, visited the area in September 1923 at the invitation of Alexander Ringhoffer, a Hungarian-born prospector living in Salt Valley. Ringhoffer had written to the railroad to interest them in the tourist potential of a scenic area he had discovered the previous year with his two sons and a son-in-law, which he called the Devils Garden (known today as the Klondike Bluffs). Wadleigh was impressed by what Ringhoffer showed him, and suggested to Park Service director Stephen T. Mather that the area be made a national monument.\n\nThe following year, additional support for the monument idea came from Laurence Gould, a University of Michigan graduate student (and future polar explorer) studying the geology of the nearby La Sal Mountains, who was shown the scenic area by local physician Dr. J. W. \"Doc\" Williams.\n\nA succession of government investigators examined the area, in part due to confusion as to the precise location. In the process, the name Devils Garden was transposed to an area on the opposite side of Salt Valley that includes Landscape Arch, the longest arch in the park. Ringhoffer's original discovery was omitted, while another area nearby, known locally as the Windows, was included. Designation of the area as a national monument was supported by the Park Service in 1926 but was resisted by President Calvin Coolidge's Interior Secretary, Hubert Work. Finally, in April 1929, shortly after his inauguration, President Herbert Hoover signed a presidential proclamation creating the Arches National Monument, consisting of two comparatively small, disconnected sections. The purpose of the reservation under the 1906 Antiquities Act was to protect the arches, spires, balanced rocks, and other sandstone formations for their scientific and educational value. The name Arches was suggested by Frank Pinkely, superintendent of the Park Service's southwestern national monuments, following a visit to the Windows section in 1925.\n\nIn late 1938, President Franklin D. Roosevelt signed a proclamation that enlarged the Arches to protect additional scenic features and permit the development of facilities to promote tourism. A small adjustment was made by President Dwight Eisenhower in 1960 to accommodate a new road alignment.\n\nIn early 1969, just before leaving office, President Lyndon B. Johnson signed a proclamation substantially enlarging the Arches. Two years later, President Richard Nixon signed legislation enacted by Congress, which significantly reduced the total area enclosed, but changed its status. Arches National Park was formally dedicated in May 1972.\n\nIn 1980, vandals attempted to use an abrasive kitchen cleanser to deface ancient petroglyphs in the park, prompting park officials to recruit physicist John F. Asmus, who specialized in using lasers to restore works of art, to use his technology to repair the damage. Asmus \"zapped the panel with intense light pulses and succeeded in removing most of the cleanser\". In 2016, there was another vandalism event on Frame Arch in the park, where a section if the rock was carved out. Due to advances in technology, in 2018 the arch was repaired through color match and modern infilling methods.",

In this section we focus on a data-selection scenario where only a very small number of in-domain sentences are used to select data from a larger unlabeled parallel corpus. An established method for data selection was proposed by BIBREF4, which was also used in training the winning systems in WMT 2019 BIBREF39, BIBREF40. This method compares the cross-entropy, according to domain-specific and non-domain-specific language models, for each candidate sentence for selection. The sentences are then ranked by the cross-entropy difference, and only the top sentences are selected for training.\nWhile the method by BIBREF4 is tried-and-true, it is based on simple n-gram language models which cannot generalize beyond the n-grams that are seen in the in-domain set. In addition, it is restricted to the in-domain and general-domain datasets it is trained on, which are usually small. On the contrary, pre-trained language models are trained on massive amounts of text, and, as we showed through unsupervised clustering, learn representations with domain-relevant information. In the following sections, we investigate whether this property of pretrained language models makes them useful for domain data selection.\nIn this section we focus on a dataselection scenario where only a very small number of in-domain sentences are used to select data from a larger unlabeled parallel corpus.",

SRL is the problem of finding predicate-argument structure in a sentence, as illustrated below:\n INLINEFORM0 \nHere, the predicate WRITE has two arguments: `Mike' as A0 or the writer, and `a book' as A1 or the thing written. The labels A0 and A1 correspond to the PropBank annotations BIBREF0 .\nAs the need for SRL arises in different domains and languages, the existing manually annotated corpora become insufficient to build supervised systems. This has motivated work on unsupervised SRL BIBREF1 , BIBREF2 , BIBREF3 . Previous work has indicated that unsupervised systems could benefit from the word alignment information in parallel text in two or more languages BIBREF4 , BIBREF5 , BIBREF6 . For example, consider the German translation of sentence INLINEFORM0 :\n INLINEFORM0 \nIf sentences INLINEFORM0 and INLINEFORM1 have the word alignments: Mike-Mike, written-geschrieben, and book-Buch, the system might be able to predict A1 for Buch, even if there is insufficient information in the monolingual German data to learn this assignment. Thus, in languages where the resources are sparse or not good enough, or the distributions are not informative, SRL systems could be made more accurate by using parallel data with resource rich or more amenable languages.\nIn this paper, we propose a joint Bayesian model for unsupervised semantic role induction in multiple languages. The model consists of individual Bayesian models for each language BIBREF3 , and crosslingual latent variables to incorporate soft role agreement between aligned constituents.

        "question": "What are the primary breathing apparatuses for scuba",
        "evidence": "Breathing apparatus\nMain article: Scuba set\n\nRecreational diver putting on his scuba set before diving\nThe defining equipment used by a scuba diver is the eponymous scuba, the self-contained underwater breathing apparatus which allows the diver to breathe while diving, and is transported by the diver. It is also commonly referred to as the scuba set.\n\nAs one descends, in addition to the normal atmospheric pressure at the surface, the water exerts increasing hydrostatic pressure of approximately 1 bar (14.7 pounds per square inch) for every 10 m (33 feet) of depth. The pressure of the inhaled breath must balance the surrounding or ambient pressure to allow controlled inflation of the lungs. It becomes virtually impossible to breathe air at normal atmospheric pressure through a tube below three feet under the water.\n\nMost recreational scuba diving is done using a half mask which covers the diver's eyes and nose, and a mouthpiece to supply the breathing gas from the demand valve or rebreather. Inhaling from a regulator's mouthpiece becomes second nature very quickly. The other common arrangement is a full face mask which covers the eyes, nose and mouth, and often allows the diver to breathe through the nose. Professional scuba divers are more likely to use full face masks, which protect the diver's airway if the diver loses consciousness.\n\nOpen-circuit\nMain article: Diving regulator\n\nAqualung Legend second stage (demand valve) regulator\n\nAqualung first stage regulator\n\nGekko dive computer with attached pressure gauge and compass\n\nSuunto submersible pressure gauge display\nOpen circuit scuba has no provision for using the breathing gas more than once for respiration. The gas inhaled from the scuba equipment is exhaled to the environment, or occasionally into another item of equipment for a special purpose, usually to increase the buoyancy of a lifting device such as a buoyancy compensator, inflatable surface marker buoy or small lifting bag. The breathing gas is generally provided from a high-pressure diving cylinder through a scuba regulator. By always providing the appropriate breathing gas at ambient pressure, demand valve regulators ensure the diver can inhale and exhale naturally and without excessive effort, regardless of depth, as and when needed.\n\nThe most commonly used scuba set uses a \"single-hose\" open circuit 2-stage demand regulator, connected to a single back-mounted high-pressure gas cylinder, with the first stage connected to the cylinder valve and the second stage at the mouthpiece. This arrangement differs from Émile Gagnan's and Jacques Cousteau's original 1942 \"twin-hose\" design, known as the Aqua-lung, in which the cylinder pressure was reduced to ambient pressure in one or two stages which were all in the housing mounted to the cylinder valve or manifold. The \"single-hose\" system has significant advantages over the original system for most applications.\n\nIn the \"single-hose\" two-stage design, the first stage regulator reduces the cylinder pressure of up to about 300 bars (4,400 psi) to an intermediate pressure (IP) of about 8 to 10 bars (120 to 150 psi) above ambient pressure. The second stage demand valve regulator, supplied by a low-pressure hose from the first stage, delivers the breathing gas at ambient pressure to the diver's mouth. The exhaled gases are exhausted directly to the environment as waste through a non-return valve on the second stage housing. The first stage typically has at least one outlet port delivering gas at full tank pressure which is connected to the diver's submersible pressure gauge or dive computer, to show how much breathing gas remains in the cylinder.\n\nRebreather\n\nAn Inspiration electronic fully closed circuit rebreather\nMain article: Diving rebreather\nLess common are closed circuit (CCR) and semi-closed (SCR) rebreathers which, unlike open-circuit sets that vent off all exhaled gases, process all or part of each exhaled breath for re-use by removing the carbon dioxide and replacing the oxygen used by the diver. Rebreathers release few or no gas bubbles into the water, and use much less stored gas volume, for an equivalent depth and time because exhaled oxygen is recovered; this has advantages for research, military, photography, and other applications. Rebreathers are more complex and more expensive than open-circuit scuba, and special training and correct maintenance are required for them to be safely used, due to the larger variety of potential failure modes.\n\nIn a closed-circuit rebreather the oxygen partial pressure in the rebreather is controlled, so it can be maintained at a safe continuous maximum, which reduces the inert gas (nitrogen and/or helium) partial pressure in the breathing loop. Minimising the inert gas loading of the diver's tissues for a given dive profile reduces the decompression obligation. This requires continuous monitoring of actual partial pressures with time and for maximum effectiveness requires real-time computer processing by the diver's decompression computer. Decompression can be much reduced compared to fixed ratio gas mixes used in other scuba systems and, as a result, divers can stay down longer or require less time to decompress. A semi-closed circuit rebreather injects a constant mass flow of a fixed breathing gas mixture into the breathing loop, or replaces a specific percentage of the respired volume, so the partial pressure of oxygen at any time during the dive depends on the diver's oxygen consumption and/or breathing rate. Planning decompression requirements requires a more conservative approach for a SCR than for a CCR, but decompression computers with a real-time oxygen partial pressure input can optimise decompression for these systems. Because rebreathers produce very few bubbles, they do not disturb marine life or make a diver's presence known at the surface; this is useful for underwater photography, and for covert work.",

It is also easy to divide the data into training and test sets by using Bible verse numbers, which allows us to control for semantic similarity between languages in a way that would have been difficult in a corpus that is not multi-parallel. Altogether we have 1,303 translations in 990 languages that we can use for our purposes. These were chosen so that the model alphabet size is below 1000 symbols, which was satisfied by choosing only translations in Latin, Cyrillic or Greek script.\nCertainly, there are disadvantages as well, such as the limited size (roughly 500 million tokens in total, with most languages having only one translation of the New Testament each, with roughly 200 thousand tokens), the narrow domain and the high overlap of named entities. The latter can lead to some unexpected effects when using nonsensical language vectors, as the model will then generate a sequence of random names.\nThe corpus deviates in some ways from an ideal multi-parallel corpus. Most translations are of the complete New Testament, whereas around 300 also contain the Old Testament (thus several times longer), and around ten contain only portions of the New Testament. Additionally, several languages have multiple translations, which are then concatenated. These translations may vary in age and style, but historical versions of languages (with their own ISO 639-3 code) are treated as distinct languages.

They begin by determining an area of interest to be studied. They then survey that area using a variety of methods that include laying in a grid system for testing the area of interest to locate sites.  Next, they excavate, or dig, to find evidence of past habitations. This results in recovering material culture, or artifacts. The artifacts are then taken to a laboratory where they are analyzed. This analysis including cleaning the artifacts, determining dates and functions, and entering those artifacts into a database where further statistical analysis may be performed. Once all this data is gathered and analyzed, archaeologist need to interpret what they have found. This data can tell you when a site was occupied, who lived there, what they were eating, and what time of year a site was occupied. Once the archaeologists have interpreted the data the write a report detailing the work that was done and their interpretation of the site. The report is very detailed as archaeological excavation destroys the sites being studying.

        "evidence": "We present an information extraction architecture that augments a candidate-generating parser with a deep neural network. The candidate-generating parser may leverage constraints. At the same time, the architecture gains the neural networks's ability to leverage large amounts of data to learn complex features that are tuned for the application at hand. Our method assumes the existence of a potentially noisy source of supervision INLINEFORM0 , e.g. via consistency checks of extracted data against existing databases, or via human interaction. This supervision is used to train the neural network.\nOur extraction system has three advantages over earlier work on information extraction with deep neural networks BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 :\nOur system leverages “free” data to train a deep neural network, and does not require large-scale manual annotation. The network is trained with noisy supervision provided by measures of consistency with existing databases (e.g. an extraction ts_tick_abs (US_Unemployment, 49%) would be implausible given recent US employment history). With slight modifications, our pipeline could be trained with supervision from human interaction, such as clicks on online advertisements. Learning without explicit annotations is critical in applications where large-scale manual annotation would be prohibitively expensive.\nIf an extractor for the given application has already been built, the neural network boosts its accuracy without the need to re-engineer or discard the existing solution. Even for new systems, the decoupling of candidate-generation and the neural network offers advantages: the candidate-generating parser can easily enforce contraints that would be difficult to support in an algorithm relying entirely on a neural network. Note that, in particular, a carefully engineered candidate-generating parser enforces constraints intelligently, and can in many instances eliminate the need to evaluate computationally expensive constraints, e.g. API calls.\nWe encode the candidate-generating parser's document annotations character-by-character into vectors INLINEFORM0 that also include a one-hot encoding of the character itself. We believe that this encoding makes it easier for the network to learn character-level characteristics of the entities in the semantic relation. Moreover, our encoding lends itself well to processing both by recurrent architectures (processing character-by-character input vectors INLINEFORM1 ) and convolutional architectures (performing 1D convolutions over an input matrix whose columns are vectors INLINEFORM2 ).\nIn a production setting, the neural architecture presented here reduced the number of false positive extractions in financial information extraction application by INLINEFORM0 relative to a mature system developed over the course of several years.\nWe present an information extraction architecture that augments a candidate-generating parser with a deep neural network.",

Among the Committee of Five charged by the Second Continental Congress with authoring the Declaration of Independence, Jefferson was the Declaration's primary author. Following the American Revolutionary War and prior to becoming the nation's third president in 1801, Jefferson was the first United States secretary of state under George Washington and then the nation's second vice president under John Adams.",
        "answer": "Thomas Jefferson (April 13, 1743 – July 4, 1826) was an American statesman, diplomat, lawyer, architect, philosopher, and Founding Father who served as the third president of the United States from 1801 to 1809. Among the Committee of Five charged by the Second Continental Congress with authoring the Declaration of Independence, Jefferson was the Declaration's primary author. Following the American Revolutionary War and prior to becoming the nation's third president in 1801, Jefferson was the first United States secretary of state under George Washington and then the nation's second vice president under John Adams.\n\nAmong the nation's Founding Fathers, Jefferson is considered unmatched in his intellectual depth and breadth. His passionate writings and advocacy for human rights, including freedom of thought, speech, and religion, were a leading inspiration behind the American Revolution, which ultimately gave rise to the American Revolutionary War, American independence, and the United States Constitution. Jefferson's ideas were globally influential in shaping and inspiring the Age of Enlightenment, which proved transformational in the late 17th and 18th centuries. He was a leading proponent of democracy, republicanism, and individual rights, and produced formative documents and decisions at the state, national, and international levels.\n\nDuring the American Revolution, Jefferson represented Virginia in the Second Continental Congress in Philadelphia, which adopted the Declaration of Independence on July 4, 1776. As a Virginia legislator, he drafted a state law for religious freedom. He served as the second Governor of Virginia from 1779 to 1781, during the Revolutionary War. In 1785, Jefferson was appointed the United States Minister to France, and subsequently, the nation's first secretary of state under President George Washington from 1790 to 1793. Jefferson and James Madison organized the Democratic-Republican Party to oppose the Federalist Party during the formation of the First Party System. With Madison, he anonymously wrote the Kentucky and Virginia Resolutions in 1798 and 1799, which sought to strengthen states' rights by nullifying the federal Alien and Sedition Acts.\n\nJefferson and Federalist John Adams became friends as well as political rivals, serving in the Continental Congress and drafting the Declaration of Independence together. In the 1796 presidential election between the two, Jefferson came in second, which according to electoral procedure at the time, made him vice president to Adams. Jefferson challenged Adams again in 1800 and won the presidency. After his term in office, Jefferson eventually reconciled with Adams and they shared a correspondence that lasted 14 years. He and Adams both died on the same day, July 4, 1826, which was also the 50th anniversary of Declaration of Independence.\n\nAs president, Jefferson pursued the nation's shipping and trade interests against Barbary pirates and aggressive British trade policies. Starting in 1803, he promoted a western expansionist policy with the Louisiana Purchase, which doubled the nation's claimed land area. To make room for settlement, Jefferson began the process of Indian tribal removal from the newly acquired territory. As a result of peace negotiations with France, his administration reduced military forces. He was re-elected in 1804, but his second term was beset with difficulties at home, including the trial of former vice president Aaron Burr. In 1807, American foreign trade was diminished when Jefferson implemented the Embargo Act in response to British threats to U.S. shipping. The same year, Jefferson signed the Act Prohibiting Importation of Slaves.\n\nJefferson was a plantation owner, lawyer, and politician, and mastered many disciplines including surveying, mathematics, horticulture, and mechanics. He was also an architect in the Palladian tradition. Jefferson's keen interest in religion and philosophy led to his appointment as president of the American Philosophical Society. He largely shunned organized religion but was influenced by Christianity, Epicureanism, and deism. Jefferson rejected fundamental Christianity, denying Christ's divinity. A philologist, Jefferson knew several languages. He was a prolific letter writer and corresponded with many prominent people, including Edward Carrington, John Taylor of Caroline, and James Madison. In 1785, Jefferson authored Notes on the State of Virginia, considered perhaps the most important American book published before 1800. Jefferson championed the ideals, values, and teachings of the Enlightenment.\n\nSince the 1790s, Jefferson was rumored to have had children by his sister-in-law and slave Sally Hemings, leading to what is known as the Jefferson-Hemings controversy. A 1998 DNA test concluded that one of Sally Hemings's children, Eston Hemings, was of the Jefferson male line. According to scholarly consensus, based on documentary and statistical evaluation, as well as oral history, Jefferson probably fathered at least six children with Hemings, including four that survived to adulthood.\n\nAfter retiring from public office, Jefferson founded the University of Virginia. Presidential scholars and historians generally praise Jefferson's public achievements, including his advocacy of religious freedom and tolerance in Virginia, his peaceful acquisition of the Louisiana Territory from France without war or controversy, and his ambitious and successful Lewis and Clark Expedition. Some modern historians are critical of Jefferson's personal involvement with slavery. Jefferson is consistently ranked among the top ten presidents of American history.",

        "answer": "Both VEX and FIRST have very strong robotics competitions for the high school level.  If you are a parent choosing between the two, multiple factors need to be taken into consideration.\nThe first factor is the availability of a robotics program in your area.  While you can form an independent team that is not affiliated with your school or another organization, it will require a significant financial and time investment.  At the high school level teams typically design their robots with CAD software and must machine the parts themselves.  Teams often consist of 20 or more members so that all of the aspects of the competition can be covered, such as creating and assembling the hardware, electrical wiring, systems design, programming and documenting the engineering process.  All of the parts and equipment need to be purchased and maintained, and members put in a lot of hours during the competition season.  Joining a pre-existing team that already has equipment, members and mentors familiar with a program will make it easiest for a child to participate, regardless of which competition the team is a part of.\nIf both VEX and FIRST programs are available, then it depends on how intense of an experience the child is interested in.  The VEX competition has a lower barrier to entry because it requires smaller robots.  Two pairs of robots compete against each other in a match to see which pair can get more points.  While teams will need to machine some parts and must have skills in electrical and software design, a team can be smaller and still compete effectively.  The FIRST competition involves much larger and more complex robots and challenges.  Two alliances of three robots each compete against each other in a match, with a total of six robots on the field at once.  Teams need to have more members to effectively compete, and participants need more in-depth training on hardware, electrical, system and software design.  There is also a business requirement, where teams have to create a marketing banner, brochure and video for their team to submit as part of the competition.\nWhether you choose VEX or FIRST, a child in high school that participates in a well-run robotics program will gain valuable engineering and organizational experience that will serve them well, both on a college application and after graduation.",

In support of energy metabolism, carnitine transports long-chain fatty acids into mitochondria to be oxidized for free energy production, and also participates in removing products of metabolism from cells. Given its key metabolic roles, carnitine is concentrated in tissues like skeletal and cardiac muscle that metabolize fatty acids as an energy source. Generally individuals, including strict vegetarians, synthesize enough L-carnitine in vivo.\n\nCarnitine exists as one of two stereoisomers (the two enantiomers d-carnitine (S-(+)-) and l-carnitine (R-(−)-)). Both are biologically active, but only l-carnitine naturally occurs in animals, and d-carnitine is toxic as it inhibits the activity of the l-form. At room temperature, pure carnitine is a whiteish powder, and a water-soluble zwitterion with relatively low toxicity. Derived from amino acids, carnitine was first extracted from meat extracts in 1905, leading to its name from Latin, \"caro/carnis\" or flesh.\n\nSome individuals with genetic or medical disorders (such as preterm infants) cannot make enough carnitine, requiring dietary supplementation.

        "evidence": "x s * ← Rapid optimization of x s * IG-score using the oracle 6:\nx s n ← [x s * , x s n−1 ] Combine optimized samples with existing samples 7: end for DARK (Algorithm 1) tackles the primary limitation on effectively learning models, which is having suitable sequences to train and test against. The first step is to take some initial set of samples x s 0 to train an initial sampling model p γ 1 (x s 0 ) with parameters γ 1 ∈ Γ. Here we use the aforementioned seed samples, but this could be random sequences or sequences from DARK 0 -Grad, an approach we developed that backpropagates the negative IG-score to generate samples (Appendix A.2), in a fashion similar to. We use the seed samples out of convenience as they have the highest score, and we reasoned that they would require less iterations by comparison. The sampling models are all generative sequence models that can be sampled. After training p γ 1 (x s 0 ), it is used to generate a large set of samples x s * . Instead of then training a new sampling model on x s * , each sequence in x s * is quickly optimized to improve the IG-score. This is done by a quick greedy hill-climb on the sequence for a set number of steps (Line 5 in Algorithm 1), which we refer to as refinement. In each step, a random position is mutated. If it improves the IG-score then it is kept, otherwise it is discarded. We use 3000 steps, a fraction of the steps done in DARK 0 , as this was found to improve the average IG-score of x s * to approximately equal to the IG-score of x s 0 . For simplicity, this is fixed for all steps. The result of optimizing x s * is then combined with x s 0 to make x s 1 . In the second iteration, x s 1 is used to train a new sampling model p γ 2 (x s 1 ). After some number of iterations N , the final sampling model is viewed as a strong prior over x d , also making it a powerful generative model that can be used for de novo design tasks. Here we perform 3 iterations with training set sizes of 15K, 100K, and 500K, where the difference is sampled and refined between iterations. These sample sizes are arbitrary and they were entirely dictated by computational resources available at the time. Three iterations were performed as we believed it sufficient to demonstrate DARK's effectiveness. We note that the iterative aspect of DARK shares similarities to methods like Estimation of Distribution Algorithms (EDAs), a common approach in model based optimization (MBO). Viewed through this lens, it suggests a number of ways that DARK can be adapted and potentially improved on, which we leave for future work.\nIn DARK, we use deep autoregressive language models for learning protein sequence distributions. Specifically, we use a standard Transformer decoder architecture which has been used extensively to train state-of-the-art language models capable of generating high-quality synthetic sequence samples. In the first iteration of DARK we use a small decoder model, termed DARK 1 , with 4 layers, 4 heads, and a feed-forward size of H = 128. To affirm the choice of self-attention based architecture, we compare it to a 1layer LSTM with a hidden dimension H = 128. We also include results for a variant of DARK 1 referred to as DARK 1 -Adversarial, that uses DMPfold2 as an adversarial regularizer during training (Appendix A.3). After the first iteration, the second and third iteration models, DARK 2 and DARK 3 respectively, use a decoder with 12 layers, 12 heads, and H = 768. The parameters are increased to coincide with the order of magnitude change in the size of the training set from DARK 1 to DARK 2 .\nTo provide a even comparison to models trained on natural sequences, we train a model, termed UF50, on 50M natural sequences from the UniRef50 sequence database (The UniProt Consortium, 2021) using the same architecture as DARK 3 (Appendix A.5). For all trained models we perform early stopping and a small amount of hyper-parameter optimization on the validation set.\nQuantitatively measuring sample quality We define high-quality samples as those that are diverse, have sequences unlike any natural sequence, and are predicted to have a stable and ordered structure. In de novo design, the most important test of a candidate sequence is that it is confidently predicted to have a stable and ordered atomistic structure. We provide a direct measure of both confidence and order jointly using AlphaFold's pLDDT score, being its confidence metric, which ranges from 0 to 100. This is a measure of confidence, and an indirect measure of order. It was found that low scores (pLDDT< 50) strongly suggest disorder and vice versa. Thus, we use the proportion of samples with a pLDDT> 70 as a measure of high quality for the predicted structures, which we refer to as Good+ pLDDT, indicating \"good or better\" quality according to criteria in. When discussing results we use 'ordered' to mean 'confidently predicted and ordered'. Using AlphaFold also provides a check to ensure that the model has not learned to produce adversarial examples against the original DMPfold2 oracle. We also measure the diversity of sequences and predicted structures using the estimated number of clusters in samples of sequences, and samples of predicted structures (See Appendix B.7 & B.8). Measuring the structural generality of DARK in a strict setting We take two key approaches to providing a stringent measure of how well DARK generalizes with regards to structure. Both are enabled by using AlphaFold to generate all-atom structure predictions for all 100,000 sequences contained in the DARK 2 training set, which covers the 15,000 seed samples and the 85,000 samples from the first iteration of DARK. We then assign each sample's structure to a topology. This process is the repeated for the 950 sequence validation set; we ignore the 950 sequence test set for what is described here. The first approach we take is to carefully construct a strict training and test set split based on structure, from the 100K samples (See Appendix B.2 for exhaustive details). This has been recently suggested for machine learning-based protein design studies and is considered a gold-standard approach in protein structure prediction. Our strict test set contains no sequences with overlapping topologies in either the training set or validation set. We also remove any sequences from the validation and training set that are detected to be similar to those in the test set with the MMseqs2 search tool . We train and evaluate a model on these sets, termed DARK 2 -STRICT. In the limit of working with synthetic, we believe this constitutes a stringent test of generality. The second approach we take is to compare the number of unique topologies represented by the 15,000 seed samples and those represented by the 85,000 sequences from the first iteration of DARK to show that DARK iterations generate sequences with unseen structures.\nTable 1: Perplexities (PPLs), IG-scores, & Sampling Speed for protein language models. Lower PPL is better and higher IG-score is better. IG-scores are calculated from 1000 sequence samples except the 15K DARK0-Seed Samples. IG-scores for refined (Ref) samples are included for DARK models. Sampling Speed is for a single example (See Appendix A.6 for further details).",

These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification.

        "answer": "The authors present the first formal representation of scripts as Hidden Markov Models (HMMs).",
        "evidence": " Scripts were developed as a means of representing stereotypical event sequences and interactions in narratives. The benefits of scripts for encoding common sense knowledge, filling in gaps in a story, resolving ambiguous references, and answering comprehension questions have been amply demonstrated in the early work in natural language understanding BIBREF0 . The earliest attempts to learn scripts were based on explanation-based learning, which can be characterized as example-guided deduction from first principles BIBREF1 , BIBREF2 . While this approach is successful in generalizing from a small number of examples, it requires a strong domain theory, which limits its applicability.\nMore recently, some new graph-based algorithms for inducing script-like structures from text have emerged. “Narrative Chains” is a narrative model similar to Scripts BIBREF3 . Each Narrative Chain is a directed graph indicating the most frequent temporal relationship between the events in the chain. Narrative Chains are learned by a novel application of pairwise mutual information and temporal relation learning. Another graph learning approach employs Multiple Sequence Alignment in conjunction with a semantic similarity function to cluster sequences of event descriptions into a directed graph BIBREF4 . More recently still, graphical models have been proposed for representing script-like knowledge, but these lack the temporal component that is central to this paper and to the early script work. These models instead focus on learning bags of related events BIBREF5 , BIBREF6 .\nWhile the above approches demonstrate the learnability of script-like knowledge, they do not offer a probabilistic framework to reason robustly under uncertainty taking into account the temporal order of events. In this paper we present the first formal representation of scripts as Hidden Markov Models (HMMs), which support robust inference and effective learning algorithms. The states of the HMM correspond to event types in scripts, such as entering a restaurant or opening a door. Observations correspond to natural language sentences that describe the event instances that occur in the story, e.g., “John went to Starbucks. He came back after ten minutes.” The standard inference algorithms, such as the Forward-Backward algorithm, are able to answer questions about the hidden states given the observed sentences, for example, “What did John do in Starbucks?”\nThere are two complications that need to be dealt with to adapt HMMs to model narrative scripts. First, both the set of states, i.e., event types, and the set of observations are not pre-specified but are to be learned from data. We assume that the set of possible observations and the set of event types to be bounded but unknown. We employ the clustering algorithm proposed in BIBREF4 to reduce the natural language sentences, i.e., event descriptions, to a small set of observations and states based on their Wordnet similarity.\nThe second complication of narrative texts is that many events may be omitted either in the narration or by the event extraction process. More importantly, there is no indication of a time lapse or a gap in the story, so the standard forward-backward algorithm does not apply. To account for this, we allow the states to skip generating observations with some probability. This kind of HMMs, with insertions and gaps, have been considered previously in speech processing BIBREF7 and in computational biology BIBREF8 . We refine these models by allowing state-dependent missingness, without introducing additional “insert states” or “delete states” as in BIBREF8 . In this paper, we restrict our attention to the so-called “Left-to-Right HMMs” which have acyclic graphical structure with possible self-loops, as they support more efficient inference algorithms than general HMMs and suffice to model most of the natural scripts. We consider the problem of learning the structure and parameters of scripts in the form of HMMs from sequences of natural language sentences. Our solution to script learning is a novel bottom-up method for structure learning, called SEM-HMM, which is inspired by Bayesian Model Merging (BMM) BIBREF9 and Structural Expectation Maximization (SEM) BIBREF10 . It starts with a fully enumerated HMM representation of the event sequences and incrementally merges states and deletes edges to improve the posterior probability of the structure and the parameters given the data. We compare our approach to several informed baselines on many natural datasets and show its superior performance. We believe our work represents the first formalization of scripts that supports probabilistic inference, and paves the way for robust understanding of natural language texts.\nIn this paper we present the first formal representation of scripts as Hidden Markov Models (HMMs), which support robust inference and effective learning algorithms.",

        "evidence": "In this section, we present the results of our experiments on the automatic detection of cyberbullying-related posts in an English (EN) and Dutch (NL) corpus of ASKfm posts. Ten-fold cross-validation was performed in exhaustive grid-search over different feature type and hyperparameter combinations (see Section SECREF4 ). The unoptimised word INLINEFORM0 -gram-based classifier and keyword-matching system serve as baselines for comparison. Precision, Recall and F INLINEFORM1 performance metrics were calculated on the positive class (i.e., `binary averaging'). We also report Area Under the ROC curve (AUC) scores, a performance metric that is more robust to data imbalance than precision, recall and micro-averaged F-score BIBREF74 .\nTable TABREF45 gives us an indication of which feature type combinations score best and hence contribute most to this task. A total of 31 feature type combinations, each with 28 different hyperparameter sets have been tested. Table TABREF45 shows the results for the three best scoring systems by included feature types with optimised hyperparameters. The maximum attained F INLINEFORM0 -score in cross-validation is 64.26% for English and 61.20% for Dutch and shows that the classifier benefits from a variety of feature types. The results on the holdout test set show that the trained systems generalise well on unseen data, indicating little under- or overfitting. The simple keyword-matching baseline system has the lowest performance for both languages even though it obtains high recall for English, suggesting that profane language characterises many cyberbullying-related posts. Feature group and hyperparameter optimisation provides a considerable performance increase over the unoptimised word INLINEFORM1 -gram baseline system. The top-scoring systems for each language do not differ a lot in performance, except the best system for Dutch, which trades recall for precision when compared to the runner-ups.\nTable TABREF47 presents the scores of the (hyperparameter-optimised) single feature type systems, to gain insight into the performance of these feature types when used individually. Analysis of the combined and single feature type sets reveals that word INLINEFORM0 -grams, character INLINEFORM1 -grams, and subjectivity lexicons prove to be strong features for this task. In effect, adding character INLINEFORM2 -grams always improved classification performance for both languages. They likely provide robustness to lexical variation in social media text, as compared to word INLINEFORM3 -grams. While subjectivity lexicons appear to be discriminative features, term lists perform badly on their own as well as in combinations for both languages. This shows once again (cf. profanity baseline) that cyberbullying detection requires more sophisticated information sources than profanity lists. Topic models seem to do badly for both languages on their own, but in combination, they improve Dutch performance consistently. A possible explanation for their varying performance in both languages would be that the topic models trained on the Dutch background corpus are of better quality than the English ones. In effect, a random selection of background corpus texts reveals that the English scrape contains more noisy data (i.e., low word-count posts and non-English posts) than the Dutch data.\nA shallow qualitative analysis of the classification output provided insight into some of the classification mistakes.\nTable TABREF52 gives an overview of the error rates per cyberbullying category of the best performing and baseline systems. This could give an indication of which types of bullying the current system has trouble classifying. All categories are always considered positive for cyberbullying (i.e., the error rate equals the false negative rate), except for Sexual and Insult which can also be negative (in case of harmless sexual talk and `socially acceptable' insulting language like `hi bitches, in for a movie?' the corresponding category was indicated, but the post itself was not annotated as cyberbullying) and Not cyberbullying, which is always negative. Error rates often being lowest for the profanity baseline confirms that it performs particularly well in terms of recall (at the expense of precision, see Table TABREF47 ) When looking at the best system for both languages, we see that Defense is the hardest category to correctly classify. This should not be a surprise as the category comprises defensive posts from bystanders and victims, which contain less aggressive language than cyberbullying attacks and are often shorter in length than the latter. Assertive defensive posts (i.e., a subcategory of Defense) that attack the bully) are, however, more often correctly classified. There are not enough instances of Encouragement for either language in the holdout to be representative. In both languages, threats, curses and incidences of sexual harassment are most easily recognisable, showing (far) lower error rates than the categories Defamation, Defense, Encouragements to the harasser, and Insult.\nQualitative error analysis of the English and Dutch predictions reveals that false positives often contain aggressive language directed at a second person, often denoting personal flaws or containing sexual and profanity words. We see that misclassifications are often short posts containing just a few words and that false negatives often lack explicit verbal signs of cyberbullying (e.g. insulting or profane words) or are ironic (examples 2 and 3). Additionally, we see that cyberbullying posts containing misspellings or grammatical errors and incomplete words are also hard to recognise as such (examples 4 and 5). The Dutch and English data are overall similar with respect to qualitative properties of classification errors.\nIn short, the experiments show that our classifier clearly outperforms both a keyword-based and word INLINEFORM0 -gram baseline. However, analysis of the classifier output reveals that false negatives often lack explicit clues that cyberbullying is going on, indicating that our system might benefit from irony recognition and integrating world knowledge to capture such implicit realisations of cyberbullying.\nGiven that we present the first elaborate research on detecting signals of cyberbullying regardless of the author role instead of bully posts alone, crude comparison with the state of the art would be irrelevant. We observe, however, that our classifier obtains competitive results compared to BIBREF32 , BIBREF33 , BIBREF35 , BIBREF34 , BIBREF37 .\nsingle feature type sets reveals that word n-grams, character n-grams, and subjectivity lexicons prove to be strong features for this task.",

        "question": "Please list all of Taylor Swift's albums, the year each one was released, and the genre of the album if it is mentioned, according to the paragraph I give.",
        "evidence": "Taylor Swift (born December 13, 1989) is an American singer-songwriter. Her genre-spanning discography, songwriting and artistic reinventions have received critical praise and wide media coverage. Born in West Reading, Pennsylvania, Swift moved to Nashville at age 14 to become a country artist. She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country singer to write a U.S. platinum-certified album.\n\nSwift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's \"Love Story\" and \"You Belong with Me\" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, \"We Are Never Ever Getting Back Together\", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs \"Shake It Off\", \"Blank Space\", and \"Bad Blood\". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single \"Look What You Made Me Do\".\n\nExiting Big Machine, Swift signed with Republic Records in 2018 and released her seventh studio album, Lover (2019), followed by the autobiographical documentary Miss Americana (2020). She ventured into indie folk and alternative rock in her 2020 albums Folklore and Evermore, whose singles \"Cardigan\" and \"Willow\" topped the Hot 100. Swift began re-recording her first six albums after a dispute over their masters, re-releasing two in 2021—Fearless (Taylor's Version) and Red (Taylor's Version). The latter's \"All Too Well (10 Minute Version)\" became the longest song to top the Hot 100. Her 2022 album Midnights and single \"Anti-Hero\" broke all-time streaming records. Swift has directed music videos and films, such as All Too Well: The Short Film (2021), and played supporting roles in others.\n\nHaving sold over 200 million records globally, Swift is one of the best-selling musicians in history. She is the most streamed woman on Spotify, and the only act to have five albums open with over one million copies sold in the US. Among her accolades are 12 Grammy Awards, including three Album of the Year wins; an Emmy Award; 40 American Music Awards; 29 Billboard Music Awards; three IFPI Global Recording Artist of the Year awards; and 92 Guinness World Records. Swift has been featured in rankings such as Rolling Stone's 100 Greatest Songwriters of All Time, Billboard's Greatest of All Time Artists, the Time 100 and Forbes Celebrity 100. Honored with titles such as Artist of the Decade and Woman of the Decade, Swift is an advocate for artists' rights and women's empowerment. Her music is credited with influencing a generation of singer-songwriters.",

        "question": "What dataset do they propose?",
        "answer": "Multilingual Persona-Chat.",
        "evidence": "Personalized dialogue agents have been shown efficient in conducting human-like conversation. This progress has been catalyzed thanks to existing conversational dataset such as Persona-chat BIBREF0, BIBREF1. However, the training data are provided in a single language (e.g., English), and thus the resulting systems can perform conversations only in the training language. For wide, commercial dialogue systems are required to handle a large number of languages since the smart home devices market is increasingly international BIBREF2. Therefore, creating multilingual conversational benchmarks is essential, yet challenging since it is costly to perform human annotation of data in all languages.\nA possible solution is to use translation systems before and after the model inference, a two-step translation from any language to English and from English to any language. This comes with three major problems: 1) amplification of translation errors since the current dialogue systems are far from perfect, especially with noisy input; 2) the three-stage pipeline system is significantly slower in terms of inference speed; and 3) high translation costs since the current state-of-the-art models, especially in low resources languages, are only available using costly APIs.\nIn this paper, we analyze two possible workarounds to alleviate the aforementioned challenges. The first is to build a cross-lingual transferable system by aligning cross-lingual representations, as in BIBREF3, in which the system is trained on one language and zero-shot to another language. The second is to learn a multilingual system directly from noisy multilingual data (e.g., translated data), thus getting rid of the translation system dependence at inference time.\nTo evaluate the aforementioned systems, we propose a dataset called Multilingual Persona-Chat, or XPersona, by extending the Persona-Chat corpora BIBREF1 to six languages: Chinese, French, Indonesian, Italian, Korean, and Japanese. In XPersona, the training sets are automatically translated using translation APIs with several human-in-the-loop passes of mistake correction. In contrast, the validation and test sets are annotated by human experts to facilitate both automatic and human evaluations in multiple languages.\nFurthermore, we propose competitive baselines in two training settings, namely, cross-lingual and multilingual, and compare them with translation pipeline models. Our baselines leverage pre-trained cross-lingual BIBREF4 and multilingual BIBREF5 models.\nAn extensive automatic and human evaluation BIBREF6 of our models shows that a multilingual system is able to outperform strong translation-based models and on par with or even improve the monolingual model. The cross-lingual performance is still lower than other models, which indicates that cross-lingual conversation modeling is very challenging. The main contribution of this paper are summarized as follows:\nWe present the first multilingual non-goal-oriented dialogue benchmark for evaluating multilingual generative chatbots.\nWe provide both cross-lingual and multilingual baselines and discuss their limitations to inspire future research.\nWe show the potential of multilingual systems to understand the mixed language dialogue context and generate coherent responses.\nTo evaluate the aforementioned systems, we propose a dataset called Multilingual Persona-Chat, or XPersona, by extending the Persona-Chat corpora to six languages: Chinese, French, Indonesian, Italian, Korean, and Japanese.",

Leonard Susskind said, “The three-dimensional world of ordinary experience––the universe filled with galaxies, stars, planets, houses, boulders, and people––is a hologram, an image of reality coded on a distant two-dimensional surface.\" As pointed out by Raphael Bousso, Thorn observed in 1978 that string theory admits a lower-dimensional description in which gravity emerges from it in what would now be called a holographic way.

First, we restricted our tasks to workers from the US with an approval rate of at least 95%. Second, we identified low quality workers by measuring the correlation of each worker's Likert-scores with the average of the other four scores. The worst workers (at most 5% of all labels) were removed.\nIn addition, we included trap sentences, similar as in BIBREF13 , in around 80 of the tasks. In contrast to Lloret et al.'s findings, both an obvious trap sentence (This sentence is not important) and a less obvious but unimportant one (Barack Obama graduated from Harvard Law) were consistently labeled as unimportant (1.08 and 1.14), indicating that the workers did the task properly.\nFor Likert-scale tasks, we follow Snow.2008 and calculate agreement as the average Pearson correlation of a worker's Likert-score with the average score of the remaining workers. This measure is less strict than exact label agreement and can account for close labels and high- or low-scoring workers. We observe a correlation of 0.81, indicating substantial agreement. For comparisons, the majority agreement is 0.73. To further examine the reliability of the collected data, we followed the approach of Kiritchenko.2016 and simply repeated the crowdsourcing for one of the three topics. Between the importance estimates calculated from the first and second run, we found a Pearson correlation of 0.82 (Spearman 0.78) for Likert-scale tasks and 0.69 (Spearman 0.66) for comparison tasks. This shows that the approach, despite the subjectiveness of the task, allows us to collect reliable annotations.\nIn addition to the reliability studies, we extrinsically evaluated the annotations in the task of summary evaluation. For each of the 58 peer summaries in TAC2008, we calculated a score as the sum of the importance estimates of the propositions it contains. Table TABREF13 shows how these peer scores, averaged over the three topics, correlate with the manual responsiveness scores assigned during TAC in comparison to ROUGE-2 and Pyramid scores. The results demonstrate that with both task designs, we obtain importance annotations that are similarly useful for summary evaluation as pyramid annotations or gold-standard summaries (used for ROUGE).\nBased on the pilot study, we conclude that the proposed crowdsourcing scheme allows us to obtain proper importance annotations for propositions. As workers are not required to read all documents, the annotation is much more efficient and scalable as with traditional methods.\nTo verify the proposed approach, we conducted a pilot study on Amazon Mechanical Turk using data from TAC2008 (Dang and Owczarzak, 2008).",

        "question": "What did the novel approach automatically predict?",
        "answer": "It predicts which claims should be prioritized for fact-checking.",
        "evidence": "The current coverage of the political landscape in the press and in social media has led to an unprecedented situation. Like never before, a statement in an interview, a press release, a blog note, or a tweet can spread almost instantaneously and reach the public in no time. This proliferation speed has left little time for double-checking claims against the facts, which has proven critical in politics, e.g., during the 2016 presidential campaign in the USA, which was arguably impacted by fake news in social media and by false claims.\nInvestigative journalists and volunteers have been working hard trying to get to the root of a claim and to present solid evidence in favor or against it. Manual fact-checking has proven very time-consuming, and thus automatic methods have been proposed as a way to speed-up the process. For instance, there has been work on checking the factuality/credibility of a claim, of a news article, or of an information source BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. However, less attention has been paid to other steps of the fact-checking pipeline, which is shown in Figure FIGREF1.\nThe process starts when a document is made public. First, an intrinsic analysis is carried out in which check-worthy text fragments are identified. Then, other documents that might support or rebut a claim in the document are retrieved from various sources. Finally, by comparing a claim against the retrieved evidence, a system can determine whether the claim is likely true or likely false. For instance, BIBREF8 do this on the basis of a knowledge graph derived from Wikipedia. The outcome could then be presented to a human expert for final judgment.\nIn this paper, we focus on the first step: predicting check-worthiness of claims. Our contributions can be summarized as follows:\nNew dataset: We build a new dataset of manually-annotated claims, extracted from the 2016 US presidential and vice-presidential debates, which we gathered from nine reputable sources such as CNN, NPR, and PolitiFact, and which we release to the research community.\nModeling the context: We develop a novel approach for automatically predicting which claims should be prioritized for fact-checking, based on a rich input representation. In particular, we model not only the textual content, but also the context: how the target claim relates to the current segment, to neighboring segments and sentences, and to the debate as a whole, and also how the opponents and the public react to it.\nState-of-the-art results: We achieve state-of-the-art results, outperforming a strong rivaling system by a margin, while also demonstrating that this improvement is due primarily to our modeling of the context.\nWe model the problem as a ranking task, and we train both Support Vector Machines (SVM) and Feed-forward Neural Networks (FNN) obtaining state-of-the-art results. We also analyze the relevance of the specific feature groups and we show that modeling the context yields a significant boost in performance. Finally, we also analyze whether we can learn to predict which facts are check-worthy with respect to each of the individual media sources, thus capturing their biases. It is worth noting that while trained on political debates, many features of our model can be potentially applied to other kinds of information sources, e.g., interviews and news.\nThe rest of the paper is organized as follows: Section SECREF2 discusses related work. Section SECREF3 describes the process of gathering and annotating our political debates dataset. Section SECREF4 presents our supervised approach to predicting fact-checking worthiness, including the explanation of the model and the information sources we use. Section SECREF5 presents the evaluation setup and discusses the results. Section SECREF6 provides further analysis. Finally, Section SECREF7 presents the conclusions and outlines some possible directions for future research.\nWe develop a novel approach for automatically predicting which claims should be prioritized for factchecking, based on a rich input representation.",

        "question": "What are the disadvantages of the previous approaches?",
        "answer": "However, systems have been evaluated for specific aspects of script knowledge only, these evaluation methods lack a clear connection to real-world tasks.",
        "evidence": "Ambiguity and implicitness are inherent properties of natural language that cause challenges for computational models of language understanding. In everyday communication, people assume a shared common ground which forms a basis for efficiently resolving ambiguities and for inferring implicit information. Thus, recoverable information is often left unmentioned or underspecified. Such information may include encyclopedic and commonsense knowledge. This work focuses on commonsense knowledge about everyday activities, so-called scripts.\nThis paper introduces a dataset to evaluate natural language understanding approaches with a focus on interpretation processes requiring inference based on commonsense knowledge. In particular, we present MCScript, a dataset for assessing the contribution of script knowledge to machine comprehension. Scripts are sequences of events describing stereotypical human activities (also called scenarios), for example baking a cake or taking a bus BIBREF0 . To illustrate the importance of script knowledge, consider Example ( SECREF1 ):\nWithout using commonsense knowledge, it may be difficult to tell who ate the food: Rachel or the waitress. In contrast, if we utilize commonsense knowledge, in particular, script knowledge about the eating in a restaurant scenario, we can make the following inferences: Rachel is most likely a customer, since she received an order. It is usually the customer, and not the waitress, who eats the ordered food. So She most likely refers to Rachel.\nVarious approaches for script knowledge extraction and processing have been proposed in recent years. However, systems have been evaluated for specific aspects of script knowledge only, such as event ordering BIBREF1 , BIBREF2 , event paraphrasing BIBREF3 , BIBREF4 or event prediction (namely, the narrative cloze task BIBREF5 , BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 ). These evaluation methods lack a clear connection to real-world tasks. Our MCScript dataset provides an extrinsic evaluation framework, based on text comprehension involving commonsense knowledge. This framework makes it possible to assess system performance in a multiple-choice question answering setting, without imposing any specific structural or methodical requirements.\nMCScript is a collection of (1) narrative texts, (2) questions of various types referring to these texts, and (3) pairs of answer candidates for each question. It comprises approx. 2,100 texts and a total of approx. 14,000 questions. Answering a substantial subset of questions requires knowledge beyond the facts mentioned in the text, i.e. it requires inference using commonsense knowledge about everyday activities. An example is given in Figure FIGREF2 . For both questions, the correct choice for an answer requires commonsense knowledge about the activity of planting a tree, which goes beyond what is mentioned in the text. Texts, questions, and answers were obtained through crowdsourcing. In order to ensure high quality, we manually validated and filtered the dataset. Due to our design of the data acquisition process, we ended up with a substantial subset of questions that require commonsense inference (27.4%).\nHowever, systems have been evaluated for specific aspects of script knowledge only, such as event ordering (Modi and Titov, 2014a; Modi and Titov, 2014b), event paraphrasing (Reg- neri et al., 2010; Wanzare et al., 2017) or event prediction (namely, the narrative cloze task (Chambers and Jurafsky,2008; Chambers and Jurafsky, 2009; Pichotta and Mooney, 2014; Pichotta and Mooney, 2016; Modi, 2016)).

BIBREF21 downloaded over 5M tweets which included one of 131 emotional hashtags based on Parrott's three-level categorization of emotions in seven categories: joy, sadness, anger, love, fear, thankfulness, surprise. To assess the quality of using hashtags as labels, the sampled 400 tweets randomly and after comparing human annotations by hashtag labels they came up with simple heuristics to increase the quality of labeling by ignoring tweets with quotations and URLs and only keeping tweets with 5 terms or more that have the emotional hashtags at the end of the tweets. Using these rules they extracted around 2.5M tweets. After sampling another 400 random tweets and comparing it to human annotation the saw that hashtags can classify the tweets with 95% precision. They did some pre-processing by making all words lower-case, replaced user mentions with @user, replaced letters/punctuation that is repeated more than twice with the same two letters/punctuation (e.g., ooooh INLINEFORM0 ooh, !!!!! INLINEFORM1 !!); normalized some frequently used informal expressions (e.g., ll → will, dnt INLINEFORM2 do not); and stripped hash symbols. They used a sub-sample of their dataset to figure out the best approaches for classification, and after trying two different classifiers (multinomial Naive Bayes and LIBLINEAR) and 12 different feature sets, they got their best results using logistic regression branch for LIBLINEAR classifier and a feature set consist of n-gram(n=1,2), LIWC and MPQA lexicons, WordNet-Affect and POS tags.\nIn the second one, the reported results are from a paper by BIBREF33 in which they used maximum entropy classifier with bag of words model to classify various emotional datasets.

Later two tasks that are more fine-grained came up, at the sentence and phrase (fragment) levels (Da San Martino et al., 2019). Also Da San Martino et al. (2019) were the first to propose this problem setup and release it as a shared task.",
        "evidence": "Most of the existing works on propaganda detection focus on identifying propaganda at the news article level, or even at the news outlet level with the assumption that each of the articles of the suspected propagandistic outlet are propaganda BIBREF5, BIBREF6.\nHere we study two tasks that are more fine-grained, specifically propaganda detection at the sentence and phrase (fragment) levels BIBREF4. This fine-grained setup aims to train models that identify linguistic propaganda techniques rather than distinguishing between the article source styles.\nBIBREF4 EMNLP19DaSanMartino were the first to propose this problem setup and release it as a shared task. Along with the released dataset, BIBREF4 proposed a multi-granularity neural network, which uses the deep bidirectional transformer architecture known as BERT, which features pre-trained context-dependent embeddings BIBREF0. Their system takes a joint learning approach to the sentence- and phrase-level tasks, concatenating the output representation of the less granular (sentence-level) task with the more fine-grained task using learned weights.\nIn this work we also take the BERT model as the basis of our approach and focus on the class imbalance as well as the lack of similarity between training and test data inherent to the task.\nIt is worth reflecting on the nature of the shared task dataset (PTC corpus) and its structural correspondence (or lack thereof) to some of the definitions of propaganda mentioned in the introduction. First, propaganda is a social phenomenon and takes place as an act of communication BIBREF19, and so it is more than a simple information-theoretic message of zeros and ones—it also incorporates an addresser and addressee(s), each in phatic contact (typically via broadcast media), ideally with a shared denotational code and contextual surround(s) BIBREF20.\nAs such, a dataset of decontextualised documents with labelled sentences, devoid of authorial or publisher metadata, has taken us at some remove from even a simple everyday definition of propaganda. Our models for this shared task cannot easily incorporate information about the addresser or addressee; are left to assume a shared denotational code between author and reader (one perhaps simulated with the use of pre-trained word embeddings); and they are unaware of when or where the act(s) of propagandistic communication took place. This slipperiness is illustrated in our example document (Fig. FIGREF13): note that while Sentences 3 and 7, labelled as propaganda, reflect a propagandistic attitude on the part of the journalist and/or publisher, Sentence 4—also labelled as propaganda in the training data—instead reflects a “flag-waving\" propagandistic attitude on the part of U.S. congressman Jeff Flake, via the conventions of reported speech BIBREF21. While reported speech often is signaled by specific morphosyntactic patterns (e.g. the use of double-quotes and “Flake said\") BIBREF22, we argue that human readers routinely distinguish propagandistic reportage from the propagandastic speech acts of its subjects, and to conflate these categories in a propaganda detection corpus may contribute to the occurrence of false positives/negatives.\nMost of the existing works on propaganda detection focus on identifying propaganda at the news article level, or even at the news outlet level with the assumption that each of the articles of the suspected propagandistic outlet are propaganda (Rashkin etal., 2017; Barron-Cedeno etal., 2019). Here we study two tasks that are more fine-grained, specifically propaganda detection at the sentence and phrase (fragment) levels (Da San Martino et al., 2019).

        "evidence": "BIBREF13 proposed a MP framework under which many of the recently introduced GNNs can be reformulated. MP consists in an aggregation phase followed by a combination phase BIBREF14. More precisely, let $G(V,E)$ be a graph, and let us consider $v \\in V$. At time $t+1$, a message vector $\\mathbf {m}_v^{t+1}$ is computed from the representations of the neighbors $\\mathcal {N}(v)$ of $v$:\n\nThe new representation $\\mathbf {h}^{t+1}_v$ of $v$ is then computed by combining its current feature vector $\\mathbf {h}^{t}_v$ with the message vector $\\mathbf {m}_v^{t+1}$:\n\nMessages are passed for $T$ time steps. Each step is implemented by a different layer of the MP network. Hence, iterations correspond to network depth. The final feature vector $\\mathbf {h}_v^T$ of $v$ is based on messages propagated from all the nodes in the subtree of height $T$ rooted at $v$. It captures both the topology of the neighborhood of $v$ and the distribution of the vertex representations in it.\nIf a graph-level feature vector is needed, e.g., for classification or regression, a READOUT pooling function, that must be invariant to permutations, is applied:\n\nNext, we present the MP network we developed for document understanding.\nWe represent a document as a statistical word co-occurrence network BIBREF18, BIBREF19 with a sliding window of size 2 overspanning sentences. Let us denote that graph $G(V,E)$. Each unique word in the preprocessed document is represented by a node in $G$, and an edge is added between two nodes if they are found together in at least one instantiation of the window. $G$ is directed and weighted: edge directions and weights respectively capture text flow and co-occurrence counts.\n$G$ is a compact representation of its document. In $G$, immediate neighbors are consecutive words in the same sentence. That is, paths of length 2 correspond to bigrams. Paths of length more than 2 can correspond either to traditional $n$-grams or to relaxed $n$-grams, that is, words that never appear in the same sentence but co-occur with the same word(s). Such nodes are linked through common neighbors.\nMaster node. Inspired by BIBREF3, our $G$ also includes a special document node, linked to all other nodes via unit weight bi-directional edges. In what follows, let us denote by $n$ the number of nodes in $G$, including the master node.\nWe formulate our AGGREGATE function as:\n\nwhere $\\mathbf {H}^t \\in \\mathbb {R}^{n \\times d}$ contains node features ($d$ is a hyperparameter), and $\\mathbf {A} \\in \\mathbb {R}^{n \\times n}$ is the adjacency matrix of $G$. Since $G$ is directed, $\\mathbf {A}$ is asymmetric. Also, $\\mathbf {A}$ has zero diagonal as we choose not to consider the feature of the node itself, only that of its incoming neighbors, when updating its representation. Since $G$ is weighted, the $i^{th}$ row of $A$ contains the weights of the edges incoming on node $v_i$. $\\mathbf {D} \\in \\mathbb {R}^{n \\times n}$ is the diagonal in-degree matrix of $G$. MLP denotes a multi-layer perceptron, and $\\mathbf {M}^{t+1} \\in \\mathbb {R}^{n \\times d}$ is the message matrix.\nThe use of a MLP was motivated by the observation that for graph classification, MP neural nets with 1-layer perceptrons are inferior to their MLP counterparts BIBREF14. Indeed, 1-layer perceptrons are not universal approximators of multiset functions. Note that like in BIBREF14, we use a different MLP at each layer.\nRenormalization. The rows of $\\mathbf {D}^{-1}\\mathbf {A}$ sum to 1. This is equivalent to the renormalization trick of BIBREF9, but using only the in-degrees. That is, instead of computing a weighted sum of the incoming neighbors' feature vectors, we compute a weighted average of them. The coefficients are proportional to the strength of co-occurrence between words. One should note that by averaging, we lose the ability to distinguish between different neighborhood structures in some special cases, that is, we lose injectivity. Such cases include neighborhoods in which all nodes have the same representations, and neighborhoods of different sizes containing various representations in equal proportions BIBREF14. As suggested by the results of an ablation experiment, averaging is better than summing in our application (see subsection SECREF30). Note that instead of simply summing/averaging, we also tried using GAT-like attention BIBREF11 in early experiments, without obtaining better results.\nAs far as our COMBINE function, we use the Gated Recurrent Unit BIBREF20, BIBREF21:\n\nOmitting biases for readability, we have:\n\nwhere the $\\mathbf {W}$ and $\\mathbf {U}$ matrices are trainable weight matrices not shared across time steps, $\\sigma (\\mathbf {x}) = 1/(1+\\exp (-\\mathbf {x}))$ is the sigmoid function, and $\\mathbf {R}$ and $\\mathbf {Z}$ are the parameters of the reset and update gates. The reset gate controls the amount of information from the previous time step (in $\\mathbf {H}^t$) that should propagate to the candidate representations, $\\tilde{\\mathbf {H}}^{t+1}$. The new representations $\\mathbf {H}^{t+1}$ are finally obtained by linearly interpolating between the previous and the candidate ones, using the coefficients returned by the update gate.\nInterpretation. Updating node representations through a GRU should in principle allow nodes to encode a combination of local and global signals (low and high values of $t$, resp.), by allowing them to remember about past iterations. In addition, we also explicitly consider node representations at all iterations when reading out (see Eq. DISPLAY_FORM18).\n\nAfter passing messages and performing updates for $T$ iterations, we obtain a matrix $\\mathbf {H}^T \\in \\mathbb {R}^{n \\times d}$ containing the final vertex representations. Let $\\hat{G}$ be graph $G$ without the special document node, and matrix $\\mathbf {\\hat{H}}^T \\in \\mathbb {R}^{(n-1) \\times d}$ be the corresponding representation matrix (i.e., $\\mathbf {H}^T$ without the row of the document node).\nWe use as our READOUT function the concatenation of self-attention applied to $\\mathbf {\\hat{H}}^T$ with the final document node representation. More precisely, we apply a global self-attention mechanism BIBREF22 to the rows of $\\mathbf {\\hat{H}}^T$. As shown in Eq. DISPLAY_FORM17, $\\mathbf {\\hat{H}}^T$ is first passed to a dense layer parameterized by matrix $\\mathbf {W}_A^T \\in \\mathbb {R}^{d \\times d}$. An alignment vector $\\mathbf {a}$ is then derived by comparing, via dot products, the rows of the output of the dense layer $\\mathbf {Y}^T \\in \\mathbb {R}^{(n-1) \\times d}$ with a trainable vector $\\mathbf {v}^T \\in \\mathbb {R}^d$ (initialized randomly) and normalizing with a softmax. The normalized alignment coefficients are finally used to compute the attentional vector $\\mathbf {u}^T \\in \\mathbb {R}^d$ as a weighted sum of the final representations $\\mathbf {\\hat{H}}^T$.\n\n\nNote that we tried with multiple context vectors, i.e., with a matrix $\\mathbf {V}^T$ instead of a vector $\\mathbf {v}^T$, like in BIBREF22, but results were not convincing, even when adding a regularization term to the loss to favor diversity among the rows of $\\mathbf {V}^T$.\nMaster node skip connection. $\\mathbf {h}_G^T \\in \\mathbb {R}^{2d}$ is obtained by concatenating $\\mathbf {u}^T$ and the final master node representation. That is, the master node vector bypasses the attention mechanism. This is equivalent to a skip or shortcut connection BIBREF23. The reason behind this choice is that we expect the special document node to learn a high-level summary about the document, such as its size, vocabulary, etc. (more details are given in subsection SECREF30). Therefore, by making the master node bypass the attention layer, we directly inject global information about the document into its final representation.\nMulti-readout. BIBREF14, inspired by Jumping Knowledge Networks BIBREF12, recommend to not only use the final representations when performing readout, but also that of the earlier steps. Indeed, as one iterates, node features capture more and more global information. However, retaining more local, intermediary information might be useful too. Thus, instead of applying the readout function only to $t=T$, we apply it to all time steps and concatenate the results, finally obtaining $\\mathbf {h}_G \\in \\mathbb {R}^{T \\times 2d}$ :\n\nIn effect, with this modification, we take into account features based on information aggregated from subtrees of different heights (from 1 to $T$), corresponding to local and global features.\nThrough the successive MP iterations, it could be argued that MPAD implicitly captures some soft notion of the hierarchical structure of documents (words $\\rightarrow $ bigrams $\\rightarrow $ compositions of bigrams, etc.). However, it might be beneficial to explicitly capture document hierarchy. Hierarchical architectures have brought significant improvements to many NLP tasks, such as language modeling and generation BIBREF24, BIBREF25, sentiment and topic classification BIBREF26, BIBREF27, and spoken language understanding BIBREF28, BIBREF29. Inspired by this line of research, we propose several hierarchical variants of MPAD, detailed in what follows. In all of them, we represent each sentence in the document as a word co-occurrence network, and obtain an embedding for it by applying MPAD as previously described.\nMPAD-sentence-att. Here, the sentence embeddings are simply combined through self-attention.\nMPAD-clique. In this variant, we build a complete graph where each node represents a sentence. We then feed that graph to MPAD, where the feature vectors of the nodes are initialized with the sentence embeddings previously obtained.\nMPAD-path. This variant is similar to the clique one, except that instead of a complete graph, we build a path according to the natural flow of the text. That is, two nodes are linked by a directed edge if the two sentences they represent follow each other in the document.\nNote that instead of simply summing/averaging, we also tried using GAT-like attention (Velickovic et al. 2017) in early experiments, without obtaining better results.",

        "evidence": "Writing errors can occur in many different forms – from relatively simple punctuation and determiner errors, to mistakes including word tense and form, incorrect collocations and erroneous idioms. Automatically identifying all of these errors is a challenging task, especially as the amount of available annotated data is very limited. Rei2016 showed that while some error detection algorithms perform better than others, it is additional training data that has the biggest impact on improving performance.\nBeing able to generate realistic artificial data would allow for any grammatically correct text to be transformed into annotated examples containing writing errors, producing large amounts of additional training examples. Supervised error generation systems would also provide an efficient method for anonymising the source corpus – error statistics from a private corpus can be aggregated and applied to a different target text, obscuring sensitive information in the original examination scripts. However, the task of creating incorrect data is somewhat more difficult than might initially appear – naive methods for error generation can create data that does not resemble natural errors, thereby making downstream systems learn misleading or uninformative patterns.\nPrevious work on artificial error generation (AEG) has focused on specific error types, such as prepositions and determiners BIBREF0 , BIBREF1 , or noun number errors BIBREF2 . Felice2014a investigated the use of linguistic information when generating artificial data for error correction, but also restricting the approach to only five error types. There has been very limited research on generating artificial data for all types, which is important for general-purpose error detection systems. For example, the error types investigated by Felice2014a cover only 35.74% of all errors present in the CoNLL 2014 training dataset, providing no additional information for the majority of errors.\nIn this paper, we investigate two supervised approaches for generating all types of artificial errors. We propose a framework for generating errors based on statistical machine translation (SMT), training a model to translate from correct into incorrect sentences. In addition, we describe a method for learning error patterns from an annotated corpus and transplanting them into error-free text. We evaluate the effect of introducing artificial data on two error detection benchmarks. Our results show that each method provides significant improvements over using only the available training set, and a combination of both gives an absolute improvement of 4.3% in INLINEFORM0 , without requiring any additional annotated data.\n \nIn addition, we describe a method for learning error patterns from an annotated corpus and transplanting them into error-free text.",

        "evidence": "Many machine learning models in question answering tasks often involve matching mechanism. For example, in factoid question answering such as SQuAD BIBREF1 , one needs to match between query and corpus in order to find out the most possible fragment as answer. In multiple choice question answering, such as MC Test BIBREF2 , matching mechanism can also help make the correct decision.\nThe easiest way of matching is to calculate the cosine similarity between two vectors. It is generally done by two step: First, encode text into word vectors, sentence vectors or paragraph vectors. Second, simply calculate the cosine similarity between target vectors. This method performs well when applied to word-level matching. However, as for matching between sentences or paragraphs, a single vector is not sufficient to encode all the important information. In order to solve this problem, Wang and Jiang proposed a “compare-aggregate” BIBREF3 framework that performs word-level matching using multiple techniques followed by aggregation with convolutional neural network. In their work, they show that compare-aggregate framework can effectively match two sequences through a wide range.\nAlthough \"compare-aggregate\" matching mechanism performs well on multiple question answering tasks, it has two deficiencies. First, it tends to aggregate passively through the sequence rather than take the importance of each element into account. That is, \"compare aggregate\" model considers all the sequential contents equally. Second, \"compare aggregate\" can only take few neighboring elements into account at the same time because of the limitation of CNN kernel size.\nIn this paper, we propose Query-based Attention CNN (QACNN) to deal with the deficiencies above. First, we add query-based attention mechanism into original \"compare aggregate\" model. Moreover, We re-design the aggregation mechanism in \"compare aggregate\" to a two-staged CNN architecture which comprises word-level aggregation and sentence-level aggregation. In this way, QACNN can efficiently extract features cross sentences.\nOur model consists of three components: 1) The similarity mapping layer which converts the input passage, query and choice into feature representation and perform a similarity operation to each other. 2) The attention-based CNN matching network composed of a two-staged CNN focusing on word-level and sentence-level matching respectively. 3) The prediction layer which makes the final decision.\nThe main contributions of this work are three-fold. First, we introduce a two-staged CNN architecture which integrates information from word-level to sentence-level, and then from sentence-level to passage-level. Second, we introduce attention mechanism into this net. We use specially designed CNN structure and attention mechanism to recognize the pattern of similarity map and eventually identify specific syntactic structure of queries. By transforming passage-query feature into attention maps and applying it to passage-choice matching result, we reasonably give weight to every word in the passage. Lastly, our model reaches 79.99% accuracy on the MovieQA dataset which yields top 1 result on this dataset.\nIn this paper, we propose Query-based Attention CNN (QACNN) to deal with the deficiencies above.",

Tracking these references and resolving coreference is essential for full machine comprehension of these texts. Significant progress has recently been made in reading comprehension research, due to large crowdsourced datasets BIBREF0, BIBREF1, BIBREF2, BIBREF3. However, these datasets focus largely on understanding local predicate-argument structure, with very few questions requiring long-distance entity tracking. Obtaining such questions is hard for two reasons: (1) teaching crowdworkers about coreference is challenging, with even experts disagreeing on its nuances BIBREF4, BIBREF5, BIBREF6, BIBREF7, and (2) even if we can get crowdworkers to target coreference phenomena in their questions, these questions may contain giveaways that let models arrive at the correct answer without performing the desired reasoning (see §SECREF3 for examples).\nWe introduce a new dataset, Quoref , that contains questions requiring coreferential reasoning (see examples in Figure FIGREF1). The questions are derived from paragraphs taken from a diverse set of English Wikipedia articles and are collected using an annotation process (§SECREF2) that deals with the aforementioned issues in the following ways: First, we devise a set of instructions that gets workers to find anaphoric expressions and their referents, asking questions that connect two mentions in a paragraph. These questions mostly revolve around traditional notions of coreference (Figure FIGREF1 Q1), but they can also involve referential phenomena that are more nebulous (Figure FIGREF1 Q3). Second, inspired by BIBREF8, we disallow questions that can be answered by an adversary model (uncased base BERT, BIBREF9, trained on SQuAD 1.1, BIBREF0) running in the background as the workers write questions. This adversary is not particularly skilled at answering questions requiring coreference, but can follow obvious lexical cues—it thus helps workers avoid writing questions that shortcut coreferential reasoning.\nQuoref contains more than 15K questions whose answers are spans or sets of spans in 3.5K paragraphs from English Wikipedia that can be arrived at by resolving coreference in those paragraphs. We manually analyze a sample of the dataset (§SECREF3) and find that 78% of the questions cannot be answered without resolving coreference. We also show (§SECREF4) that the best system performance is 49.1% $F_1$, while the estimated human performance is 87.2%. These findings indicate that this dataset is an appropriate benchmark for coreference-aware reading comprehension.\nWe also show (§SECREF4) that the best system performance is 49.1% $F_1$, while the estimated human performance is 87.2%.",

        "evidence": "Medical providers across the United States are required to document clinical visits in the Electronic Health Records. This need for documentation takes up a disproportionate amount of their time and attention, resulting in provider burnout BIBREF0, BIBREF1. One study found that full-time primary care physicians spent about 4.5 hours of an 11-hour workday interacting with the clinical documentation systems, yet were still unable to finish their documentation and had to spend an additional 1.4 hours after normal clinical hours BIBREF2.\nSpeech and natural language processing are now sufficiently mature that there is considerable interest, both in academia and industry, to investigate how these technologies can be exploited to simplify the task of documentation, and to allow providers to dedicate more time to patients. While domain-specific automatic speech recognition (ASR) systems that allow providers to dictate notes have been around for a while, recent work has begun to address the challenges associated with generating clinical notes directly from speech recordings. This includes inducing topic structure from conversation data, extracting relevant information, and clinical summary generation BIBREF3. In one recent work, authors outlined an end-to-end system; however, the details were scant without empirical evaluations of their building blocks BIBREF4. One of the simplistic approaches uses a hand crafted finite state machine based grammar to locate clinical entities in the ASR transcripts and map them to canonical clinical terms BIBREF5. This seems to perform well in a narrowly scoped task. A more ambitious approach mapped ASR transcripts to clinical notes by adopting a machine translation approach BIBREF6. However this performed poorly. To address the difficulty in accessing clinical data, researchers have experimented with synthetic data to develop a system for documenting nurse-initiated telephone conversations for congestive heart failure patients who are undergoing telemonitoring after they have been discharged from the hospital BIBREF7. In their task, a question-answer based model achieved an F-score of 0.80. This naturally raises the question of how well state-of-art techniques will perform in helping the broader population of clinicians such as primary care providers.\nOne might expect that the task of extracting clinical concepts from audio faces challenges similar to the domain of unstructured clinical texts. In that domain, one of the earliest public-domain tasks is the i2b2 relations challenge, defined on a small corpus of written discharge summaries consisting of 394 reports for training, 477 for test, and 877 for evaluation BIBREF8. Given the small amount of training data, not surprisingly, a disproportionately large number of teams fielded rule-based systems. Conditional random field-based (CRF) systems BIBREF9 however did better even with the limited amount of training data BIBREF10. Other i2b2/n2c2 challenges focused on coreference resolution BIBREF11, temporal relation extraction BIBREF12, drug event extraction BIBREF13 on medical records, and extracting family history BIBREF14. Even though the text was largely unstructured, they benefited from punctuation and capitalization, section headings and other cues in written domain which are unavailable in audio to the same extent.\nWith the goal of creating an automated medical scribe, we broke down the task into modular components, including ASR and speaker diarization which are described elsewhere BIBREF15. In this work, we investigate the task of extracting relevant clinical concepts from transcripts. Our key contributions include: (i) defining three tasks – the Medications Task, the Symptoms Task, and the Conditions Task along with principles employed in developing the annotation guidelines for them (Section SECREF2); (ii) measuring the label quality using inter-labeler agreements and refining the quality iteratively (Section SECREF3), (iii) evaluating the performance of the state-of-the-art models on these tasks (Section SECREF4), and (iv) a comprehensive analysis of the performance of the models including manual error categorization (Section SECREF5). The corpus we have created in this work is based on private, proprietary data that cannot be publicly shared. Instead, we are sharing the learnings from our experience that might be useful for the wider community as well as the detailed labeling guidelines as supplementary material in the extended version of this paper on arxiv.org.\nOur key contributions include: (i) defining three tasks – the Medications Task, the Symptoms Task, and the Conditions Task along with principles employed in developing the annotation guidelines for them (Section 2.);",

        "evidence": "We propose a Bayesian model of semantic role induction (SRI) that uses crosslingual latent variables to capture role alignments in parallel corpora. The crosslingual latent variables capture correlations between roles in different languages, and regularize the parameter estimates of the monolingual models. Because this is a joint Bayesian model of multilingual SRI, we can apply the same model to a variety of training scenarios just by changing the inference procedure appropriately. We evaluate monolingual SRI with a large unlabeled dataset, bilingual SRI with a parallel corpus, bilingual SRI with annotations available for the source language, and monolingual SRI with a small labeled dataset. Increasing the amount of monolingual unlabeled data significantly improves SRI in German but not in English. Adding word alignments in parallel sentences results in small, non significant improvements, even if there is some labeled data available in the source language. This difficulty in showing the usefulness of parallel corpora for SRI may be due to the current assumptions about role alignments, which mean that only a small percentage of roles are aligned. Further analyses reveals that annotating small amounts of data can easily outperform the performance gains obtained by adding large unlabeled dataset as well as adding parallel corpora.\nFuture work includes training on different language pairs, on more than two languages, and with more inclusive models of role alignment.\nThe crosslingual latent variables capture correlations between roles in different languages, and regularize the parameter estimates of the monolingual models.",

        "question": "Do the SVM and the FNN versions of the system consistently outperform all three versions of ClaimBuster on all measures?",
        "answer": "Yes, they do.",
        "evidence": "Table TABREF21 shows the performance of our models when using all features described in Section SECREF4: see the SVM$_{All}$ and the FNN$_{All}$ rows. In order to put the numbers in perspective, we also show the results for five increasingly competitive baselines.\nFirst, there is a random baseline, followed by an SVM classifier based on a bag-of-words representation with TF.IDF weights learned on the training data. Then come three versions of the ClaimBuster system: CB-Platform uses scores from the online demo, which we accessed on December 20, 2016, and SVM$_{CBfeat}$ and FNN$_{CBfeat}$ are our re-implementations, trained on our dataset.\nWe can see that all systems perform well above the random baseline. The three versions of ClaimBuster also outperform the TF.IDF baseline on most measures. Moreover, our reimplementation of ClaimBuster performs better than the online platform in terms of MAP. This is expected as their system is trained on a different dataset and it may suffer from testing on slightly out-of-domain data. At the same time, this is reassuring for our implementation of the features, and allows for a more realistic comparison to the ClaimBuster system.\nMore importantly, both the SVM and the FNN versions of our system consistently outperform all three versions of ClaimBuster on all measures. This means that the extra information coded in our model, mainly more linguistic, structural, and contextual features, has an important contribution to the overall performance.\nWe can further see that the neural network model, FNN$_{All}$, clearly outperforms the SVM model: consistently on all measures. As an example, with the precision values achieved by FNN$_{All}$, the system would rank on average 4 positive examples in the list of its top-5 choices, and also 14-15 in the top-20 list. Considering the recall at the first $R$ sentences, we will be able to encounter 43% of the total number of check-worthy sentences. This is quite remarkable given the difficulty of the task.\nMore importantly, both the SVM and the FNN versions of our system consistently outperform all three versions of ClaimBuster on all measures.",

        "answer": "The designs, accommodations and compromises for these boats can be very different and reflect the likely sea conditions these boats would encounter, expected time at sea and different experiences of passenger comfort.  The primary difference between these boats begins with the shape of the hull since many other design choices tend to be dictated by hull shape.\n\nCoastal cruisers, which are generally sailed near shore and in safer weather conditions, \ntend to have a flatter hull shapes since these boats, which means they tend to \"slap\" the water when coming off a wave.  With a flatter hull shape, boat architects can make greater use of the cabin space and so coastal cruisers will generally have a more spacious interior.  The helm (or the outdoor area from which the boat is navigated) is generally less protected and generally speaking, offers greater comfort and ease of moving around.  Safety, protection and expected time away from marinas mean these boats can refill fresh water, recharge batteries, empty waste tanks more frequently and therefore, tend to have lower capacities.\n\nBlue water boats, because they are intended to sail in open waters (hence the moniker \"blue water\") in more unpredictable weather, generally have tapered (or tear drop shaped) hull shapes with heavier keels (generally, lead) and deeper drafts.  With these designs, blue water boats can withstand heavier seas and will \"cut through\" waves rather than \"slap.\"  Generally speaking, blue water boats offer a much more comfortable experience in rougher seas and will have bigger fresh water and fuel tanks and will likely feature generators and other equipment that allows these boats to away for longer periods.\n\nBlue water boats feature tapered hulls so the beam or width of the boat narrows the closer it gets to the water line (and below), leaving less room in the interior cabin than an equally sized coastal cruiser.  Foot for foot, blue water boats will feature fewer berths and will have more cramped quarters because of the narrowing beam.\n\nBecause blue water boats are intended to sail longer distances and will carry more fuel and fresh water, these boats interior space is further restricted to accomadate these practical requirements.\n\nThe differences in comfort, stability and likelihood of capsizing are all captured in mathematical calculations that can provide an abstracted comparison between these boat types so prospective buyers can anticipate the the experiences and trade offs each hull type would provide.",

        "question": "What is the relationship between Link and Zelda?",
        "evidence": "Link is a fictional character and the protagonist of Nintendo's video game franchise The Legend of Zelda. He was created by Japanese video game designer Shigeru Miyamoto. Link was introduced as the hero of the original 1986 The Legend of Zelda video game and has appeared in a total of 19 entries in the series, as well as a number of spin-offs. Common elements in the series include Link travelling through Hyrule whilst exploring dungeons, battling creatures and solving puzzles until he eventually defeats the series' primary antagonist, Ganon, and saves Princess Zelda.\n\nThroughout The Legend of Zelda series, Link has made multiple appearances in a variety of incarnations. He has been rendered in both 2D and 3D form and has been traditionally depicted in his signature green cap and tunic carrying a sword and shield. Over the course of the series, he appears as a child or young adult of the Hylian race, which originates from the fictional kingdom of Hyrule. Within Zelda lore, Link is the soul of a legendary hero that throughout history is reincarnated within a seemingly ordinary boy or man when the need arises for a new warrior to defeat the forces of evil. To defeat Ganon, Link usually obtains the mystical Master Sword or a similar legendary weapon, which is obtained after completing various trials. Over the course of his journey, he also acquires other magical items, including musical instruments and other weaponry.\n\nIn addition to the main series, Link has appeared in other Nintendo media, including merchandise, comics and manga, and an animated television series. He is a prominent character in various spin-off games, including Hyrule Warriors, Cadence of Hyrule and Hyrule Warriors: Age of Calamity. He has appeared in entries of several other game franchises, including the Super Smash Bros. series, SoulCalibur II and Mario Kart 8, and has also been referenced in other games, such as The Elder Scrolls V: Skyrim.\n\nAlongside fellow Nintendo character Mario, Link is one of the most recognisable characters in the video game industry. He has been instrumental in the establishment of the role-playing video game genre as the protagonist of the series, which has influenced numerous other video games with its concepts of open world and nonlinear gameplay. According to Guinness World Records, Link is the most critically acclaimed videogame playable character and the most ubiquitous action-adventure video game character, surpassing Mario. He has been recognised by the Guinness World Records Gamer's Edition as the second best video game character of all time after Mario. Critics have also named him as one of the most influential video game characters of all time and one of Shigeru Miyamoto's most famous creations.\n\nLink is a brave, skilled warrior and the hero of The Legend of Zelda series. Over the course of the series, he has appeared in a variety of ages and forms, ranging from child to young adult, and in Twilight Princess, also appears in the form of a wolf. He displays the characteristic traits of the Hylian race, being of human form with elfin features, including pointed ears. Since the original 1986 The Legend of Zelda video game, he has been repeatedly depicted wearing his characteristic green cap and tunic. He has also appeared wearing other outfits, including a blue lobster shirt in The Wind Waker and his blue Champion's Tunic in Breath of the Wild. Link is described in the original game's instruction manual as a \"young lad\" and a traveller and in later games, such as Breath of the Wild, as a knight of Hyrule who is sworn to protect the kingdom and Princess Zelda. During gameplay, he carries a sword and a shield, but has also wielded a variety of other weapons, including bows, spears and axes.\n\nLink's signature weapon is the Master Sword, a powerful magic sword that has the ability to repel evil. He is also often depicted holding the Hylian Shield. These two components have become integral aspects of the character's identity. Each game in the series follows a similar story arc in which Link must take a journey that eventually leads him to recover the Master Sword, which makes him stronger in gameplay and enables him to defeat the series' main antagonist, Ganon.\n\nThroughout each game, Link is able to obtain various items during his adventures, which the player can then use in gameplay. Many of these objects possess magical properties that bestow specific abilities on Link, such as a magic cape that makes Link invisible when he wears it, or potions that replenish his health. Others have various practical purposes, such as the hookshot, which enables Link to pull items towards him, and bombs for detonation. Link has used various musical instruments on his travels, most notably, the Ocarina of Time, which when played is used for teleportation. In Breath of the Wild, Link's key tool is the Sheikah Slate, a handheld tablet featuring various runes that enable him to manipulate the game world.\n\nIn Zelda lore, Link is the reincarnated soul of a hero, chosen by the goddess Hylia to protect the kingdom of Hyrule from Ganon and save Princess Zelda whenever the need arises. As the goddess' chosen hero, he is also the bearer of the Triforce of Courage, one of the three components that combine to form the Triforce, a sacred artefact and symbol of power. In several Zelda games, Link's main objective is to recover the fragments of the Triforce in order to defeat Ganon. Link's character is always depicted as a fearless hero and a \"symbol of courage\" who is willing to protect Hyrule for the sake of others.\n\nRelationships\nLink's relationships with the other main characters has been a defining aspect of the series. Within the fictional lore, Ganon, Zelda and Link represent three pieces of the Triforce, with Ganon representing Power, Zelda representing Wisdom and Link representing Courage. This trinity transcends the fictional timeline and dictates that the three characters are destined to be forever reincarnated in an endless battle for good and evil. Link's battle with Ganon established a fictional chronology that spans across the entire series and branches into three separate timelines. The three timelines originate at the end of Ocarina of Time when the timeline splits according to whether Link successfully defeats Ganon (\"The Hero is Victorious\") or fails to stop him (the \"Fallen Hero\" timeline). The official fictional chronology was revealed in Hyrule Historia, with Skyward Sword presented as the first game in the timeline. Skyward Sword establishes that the three main characters are destined to be connected in an endless cycle after the antagonist Demise curses Link and Zelda.\n\nLink's relationship with Zelda has been a core aspect of the series but has also been the subject of speculation. Throughout the games, the storylines have suggested the possibility of a romantic relationship between the two, but this has remained ambiguous. With each game release, the nature of their relationship has varied and Link has also been presented with other possible love interests. A romantic relationship between Link and Zelda is particularly evident in Skyward Sword and was also emphasised in an official \"romance trailer\" for the game. Aonuma commented on this relationship in an interview with Game Informer: \"As far as the love story goes, it wasn't that we wanted to create a romance between Link and Zelda as much as we wanted the player to feel like this is a person who's very important to me, who I need to find. We used that hint of a romance between the two to tug at the heartstrings\". In Breath of the Wild, the relationship between Link and Zelda is more complex and follows a story arc that begins with resentment and ends in a close bond with each willing to give their life for the other.",
        "answer": "Link's relationship with Zelda has been developing as the story flows. In lore, Link, Zelda, and Ganon (the evil) represent three pieces Triforce, corresponding to Courage, Wisdom, and Power, respectively. The three are destined connected in an endless cycle.\nPeople speculate that Link and Zelda are in a possible romantic relationship. Although not told by the story, there is evidence in and out of the games that this relationship is true. The game producer, Eiji Aonuma, once said otherwise that it was not their intention to create a romantic relationship between the two, but to the most important person for each other.",

The n-gram model is widely used in natural language processing while the bag-of-words model is a simplified representation used in natural language processing and information retrieval BIBREF17 , BIBREF18 . According to the bag-of-words model, the representative vector of sentences in the document does not preserve the order of the words in the original sentences. It represents the word using term frequency collected from the document rather than the order of words or the structure of sentences in the document. The bag-of-words model is commonly used in methods of document classification, where the frequency of occurrence of each word is used as an attribute feature for training a classifier. In contrast, an n-gram is a contiguous sequence of n items from a given sequence of text. An n-gram model is a type of probabilistic language model for predicting the next item in a given sequence in form of a Markov model.

        "answer": "Yes, our meta-network learns a weight for each candidate augmentation, which is considered as adaptive selection.",
        "evidence": "Time series data in the real world is high dimensional, unstructured, and complex with unique properties, leading to challenges for data modeling. In addition, without human recognizable patterns, it is much harder to label time series data than images and languages in realworld applications. These labeling limitations hinder deep learning methods, which typically require a huge amount of labeled data for training, been applied on time series data. Representation learning learns a fixed-dimension embedding from the original time series that keeps their inherent features. Comparing to the raw time series data, these representations are with better transferability and generalization capacity. To deal with labeling limitations, contrastive learning methods have been widely adopted in various domains for their soaring performance on representation learning, including vision, language, and graph-structured data. In a nutshell, contrastive learning methods typically train an encoder to map instances to an embedding space where dissimilar (negative) instances are easily distinguishable from similar (positive) ones and model predictions to be invariant to small noise applied to either input examples or hidden states.\nDespite being effective and prevalent, contrastive learning has been less explored in the time series domain. Existing contrastive learning approaches often involve a specific data augmentation strategy that creates novel and realistic-looking training data without changing its label to construct positive alternatives for any input sample. Their success relies on carefully designed rules of thumb guided by domain expertise. Routinely used data augmentations for contrastive learning are mainly designed for image and language data, such as color distortion, flip, word replacement, and back-translation. These augmentation techniques generally do not apply to time series data.\nFigure: InfoTS is composed of three parts: (1) candidate transformation that generates different augmentations of the original inputs, (2) a meta-network that selects the optimal augmentations, (3) an encoder that learns representations of time series instances. The meta-network is learned in tandem with contrastive encoder learning.\nRecently, some researchers propose augmentations for time series to enhance the size and quality of the training data. For example, and propose to adopt jittering, scaling, and permutation strategies to generate augmented instances. extracts subsequences for data augmentation. In spite of the current progress, existing methods have two main limitations. First, unlike images with human recognizable features, time series data are often associated with inexplicable underlying patterns. Strong augmentation such as permutation may ruin such patterns and consequently, the model will mistake the negative handcrafts for positive ones. While weak augmentation methods such as jittering may generate augmented instances that are too similar to the raw inputs to be informative enough for contrastive learning. On the other hand, time series datasets from different domains may have diverse nature. Adapting a universal data augmentation method, such as subsequence in, for all datasets and tasks leads to sub-optimal performances. Other works follow empirical rules to select suitable augmentations from expensive trial-and-error. Akin to hand-crafting features, hand-picking choices of data augmentations are undesirable from the learning perspective. The diversity and heterogeneity of real-life time series data further hinder these methods away from wide applicability.\nTo address the challenges, we first introduce the criteria for selecting good data augmentations in contrastive learning. Data augmentation benefits generalizable, transferable, and robust representation learning by correctly extrapolating the input training space to a larger region. The positive instances enclose a discriminative zone in which all the data points should be similar to the original instance. The desired data augmentations for contrastive representation learning should have both high fidelity and high variety. High fidelity encourages the augmented data to maintain the semantic identity that is invariant to transformations. For example, if the downstream task is classification, then the generated augmentations of inputs should be class-preserving. Meanwhile, generating augmented samples with high variety benefits representation learning by increasing the generalization capacity. From the motivation, we theoretically analyze the information flows in data augmentations based upon information theory and derive the criteria for selecting desired time series augmentations. Due to the inexplicability in practical time series data, we assume that the semantic identity is presented by the target in the downstream task. Thus, high fidelity can be achieved by maximizing the mutual information between the downstream label and the augmented data. A one-hot pseudo label is assigned to each instance in the unsupervised setting when downstream labels are unavailable. These pseudo labels encourage augmentations of different instances to be distinguishable from each other. We show that data augmentations preserving these pseudo labels can add new information without decreasing the fidelity. Concurrently, we maximize the entropy of augmented data conditional on the original instances to increase the variety of data augmentations.\nBased on the derived criteria, we propose an adaptive data augmentation method, InfoTS (as shown in Figure), by employing a meta-learning mechanism to avoid ad-hoc choices or painstakingly trial-and-error tuning. Specifically, we utilize a meta-network to learn the augmentation prior in tandem with contrastive learning. The meta-learner automatically selects optimal augmentations from candidate augmentations to generate feasible positive samples. Along with random sampled negative instances, augmented instances are then fed into a time series encoder to learn representations in a contrastive manner. With a reparameterization trick, the meta-network can be efficiently optimized with back-propagation based upon the proposed criteria. Therefore, the meta-network can automatically select data augmentations in a per dataset and per learning task manner without resorting to expert knowledge or tedious downstream validation. Our main contributions include:\n• We propose criteria to guide the selection of data augmentations for contrastive time series representation learning without prefabricated knowledge. • We propose a meta-learning based method to automatically select feasible data augmentations for different time series datasets, which can be efficiently optimized with backpropagation. • We empirically verify the effectiveness of the proposed criteria to find optimal data augmentations. Extensive experiments demonstrate that InfoTS can achieve highly competitive performance with up to 11.4% reduction in MSE on forecasting task and up to 2.8% relative improvement in accuracy on classification task over the leading baselines.\nTo present deep insights into the proposed method, we verify key components in InfoTS with multiple ablation studies on the Electricity dataset. Results are shown in Table. 1) We verify the effectiveness of the adopted contrastive learning objective, Eq. (), by comparing InfoTS with its two variants. \"w/o Local\" removes the local contrastive loss between subsequences and \"w/o Global\" removes the instance-level contrastive loss. The comparison between these variants and InfoTS demonstrates that both instance-level and intra-temporal objectives are important in contrastive learning for time series data. 2) To demonstrate the advantage of adaptive selection of augmentations, we compare InfoTS with variants \"Random\" and \"All\". \"Random\" randomly selects an augmentation from candidate transformation functions each time and \"All\" sequentially applies transformations to generate augmented instances. Performance decreases are observed in these variances, verifying the key role of adaptive selection in our method. 3) To show the effects of variety and fidelity objectives in meta-network training, we include two variants, \"w/o Fidelity\" and \"w/o Variety\", which dismiss the fidelity or variety objective, respectively. The comparison between InfoTS and the variants empirically confirms both variety and fidelity are important for data augmentation in contrastive learning. Note that the adopted basic augmentations are manually tuned in a previous paper with high qualities for contrastive learning. Including low quality basic augmentations, we conduct more ablation studies are shown in Appendix D.3.\nBased on the derived criteria, we propose an adaptive data augmentation method, InfoTS (as shown in Figure 1), by employing a meta-learning mechanism to avoid ad-hoc choices or painstakingly trial-and-error tuning. Specifically, we utilize a meta-network to learn the augmentation prior in tandem with contrastive learning. The meta-learner automatically selects optimal augmentations from candidate augmentations to generate feasible positive samples.****To demonstrate the advantage of adaptive selection of augmentations, we compare InfoTS with variants “Random” and “All”.****To show that our InfoTS can adaptively detect the most effective augmentation based on the data distribution, we follow the setting in Section 4.4 and conduct more ablation studies to investigate comprehensively into the proposed model. We compare performances of variants that each applies a single transformation to generate augmented instances in Table 5. From the table, we know that augmentation with subsequence benefits the most for the Electricity dataset. We visualize the weight weight updating process of InfoTS in Figure 8, with each line representing the normalized importance score of the corresponding transformation. The weight for subsequence increase with the epoch, showing that InfoTS tends to adopt subsequence as the optimal transformation. Consistency between accuracy performance and weight updating process demonstrates the effectiveness of InfoTS to adaptively select feasible transformations. Besides, as shown in Table 5, InfoTS outperforms the variant that uses subsequence only. This comparison shows that the meta-network learns to consider the combinations, which is better than any (single) candidate augmentation.",

However, the memory network described in Section SECREF3 has only one memory slot with size INLINEFORM0 to represent a clause, where INLINEFORM1 is the dimension of a word embedding and INLINEFORM2 is the length of a clause. It means that when the memory network models a clause, it only considers each word separately.\nIn order to capture [id=lq]context information for clauses, we propose a new architecture which contains more memory slot to model the context with a convolutional operation. The basic architecture of Convolutional Multiple-Slot Memory Network (in short: ConvMS-Memnet) is shown in Figure 4.\nConsidering the text length is usually short in the dataset used here for emotion cause extraction, we set the size of the convolutional kernel to 3. That is, the weight of word INLINEFORM0 [id=lq]in the INLINEFORM1 -th position considers both the previous word INLINEFORM2 and the following word INLINEFORM3 by a convolutional operation: DISPLAYFORM0 \nFor the first and the last word in a clause, we use zero padding, INLINEFORM0 , where INLINEFORM1 is the length of a clause. Then, the attention [id=lq]weightsignal for each word position in the clause is [id=lq]now defined as: DISPLAYFORM0 \nNote that we obtain the attention for each position rather than each word.

The concatenation of three output vectors forms a sequence-level feature which can be used in the training.

It is the second longest-lived radioisotope of iodine, after iodine-129.\nIts half-life is 59.49 days and it decays by electron capture to an excited state of tellurium-125. This state is not the metastable 125mTe, but rather a lower energy state that decays immediately by gamma decay with a maximum energy of 35 keV. Some of the excess energy of the excited 125Te may be internally converted ejected electrons (also at 35 keV), or to x-rays (from electron bremsstrahlung), and also a total of 21 Auger electrons, which are produced at the low energies of 50 to 500 electron volts. Eventually, stable ground state 125Te is produced as the final decay product.\nIn medical applications, the internal conversion and Auger electrons cause little damage outside the cell which contains the isotope atom. The X-rays and gamma rays are of low enough energy to deliver a higher radiation dose selectively to nearby tissues, in \"permanent\" brachytherapy where the isotope capsules are left in place (125I competes with palladium-103 in such uses)\nBecause of its relatively long half-life and emission of low-energy photons which can be detected by gamma-counter crystal detectors, 125I is a preferred isotope for tagging antibodies in radioimmunoassay and other gamma-counting procedures involving proteins outside the body. The same properties of the isotope make it useful for brachytherapy, and for certain nuclear medicine scanning procedures, in which it is attached to proteins (albumin or fibrinogen), and where a half-life longer than that provided by 123I is required for diagnostic or lab tests lasting several days.\nIodine-125 can be used in scanning/imaging the thyroid, but iodine-123 is preferred for this purpose, due to better radiation penetration and shorter half-life (13 hours). 125I is useful for glomerular filtration rate (GFR) testing in the diagnosis or monitoring of patients with kidney disease.

Popular NLP tasks including sentiment analysis, propaganda detection, and event extraction from social media are all examples of imbalanced classification problems. In each case the number of elements in one of the classes (e.g. negative sentiment, propagandistic content, or specific events discussed on social media, respectively) is significantly lower than the number of elements in the other classes.\nThe recently introduced BERT language model for transfer learning BIBREF0 uses a deep bidirectional transformer architecture to produce pre-trained context-dependent embeddings. It has proven to be powerful in solving many NLP tasks and, as we find, also appears to handle imbalanced classification well, thus removing the need to use standard methods of data augmentation to mitigate this problem (see Section SECREF11 for related work and Section SECREF16 for analysis).\nBERT is credited with the ability to adapt to many tasks and data with very little training BIBREF0.

        "evidence": "The history of coffee dates back to centuries of old oral tradition in modern day Ethiopia. However, neither where coffee was first cultivated nor direct evidence of its consumption prior to the 15th century have been found. Sufi monasteries in Yemen employed coffee as an aid to concentration during prayers. Coffee later spread to the Levant and Persia in the early 16th century; it caused some controversy on whether it was halal in Ottoman and Mamluk society. Coffee arrived in Italy the second half of the 16th century through commercial Mediterranean trade routes, while Central and Eastern Europeans learnt of coffee from the Ottomans. By the mid 17th century, it had reached India and the East Indies.\n\n\nCoffeepot (cafetière \"campanienne\"), part of a service, 1836, hard-paste porcelain, Metropolitan Museum of Art\nCoffee houses would establish themselves in Western Europe by the late 17th century, especially in England and Germany. One of the earliest cultivations of coffee in the New World was when Gabriel de Clieu brought coffee seedlings to Martinique in 1720. These beans later sprouted 18,680 coffee trees which enabled its spread to other Caribbean islands like Saint-Domingue and also to Mexico. By 1788, Saint-Domingue supplied half the world's coffee.\n\nBy 1852, globally, Brazil became the largest producer of coffee and has held that status ever since. The period since 1950 saw the widening of the playing field due to the emergence of several other major producers, notably Colombia, Ivory Coast, Ethiopia, and Vietnam; the latter overtook Colombia and became the second-largest producer in 1999.

        "evidence": "Language modeling is a probabilistic description of language phenomenon. It provides essential context to distinguish words which sound similar and therefore has one of the most useful applications in Natural Language Processing (NLP) especially in downstreaming tasks like Automatic Speech Recognition (ASR). Recurrent Neural Networks (RNN) especially Long Short Term Memory (LSTM) networks BIBREF0 have been the typical solution to language modeling which do achieve strong results. In spite of these results, their fundamental sequential computation constraint has restricted their use in the modeling of long-term dependencies in sequential data. To address these issues Transformer architecture was introduced. Transformers relies completely on an attention mechanism to form global dependencies between input and output. It also offers more parallelization and has achieved SOTA results in language modeling outperforming LSTM models BIBREF1.\nIn recent years,we have seen a lot of development based on this standard transformer models particularly on unsupervised pre-training(BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 which have set state-of-the art results on multiple NLP benchmarks. One such model architecture has been the Bidirectional Encoder Representations from Transformers (BERT) model which uses a deep bidirectional transformer architecture.\nAnother architecture of interest would be the Transformer-XL, which introduces the notion of recurrence in a self-attention model.\nThe primary research focus though has been mostly on English language for which abundant data is present. It is interesting to see the performance of these models for an agglutinative language like Finnish, which is morphologically richer than English.\nIn this project, we explore the implementation of Transformer-based models (BERT and Transformer-XL) in language modeling for Finnish. We will use the same training data as in BIBREF8 so that we can do fair comparisons with the performance of the LSTM models. Also, as the BERT model is a bi-directional transformer, we will have to approximate the conditional probabilities given a sequence of words. We also experiment with using sub-word units with Transformer-XL to cope with the large vocabulary problems associated with the Finnish Language. With smaller units, the modeled sequences are longer, and we hope that the recursive XL architecture can allow us to still model long term effects. To the best of our knowledge this is the first work with the Finnish language to use the following:\nApproximation of perplexity using a BERT architecture\nUsing Transformer-XL architecture with sub-word units.\nComparison of Transformer and LSTM models as language models in the same comparable settings with an agglutinative language.\nWe will use the same training data as in [9] so that we can do fair comparisons with the performance of the LSTM models.",

        "question": "Given a reference text about GDPR, tell me how GDPR helps to secure personal data.",
        "evidence": "The General Data Protection Regulation (2016/679, \"GDPR\") is a Regulation in EU law on data protection and privacy in the EU and the European Economic Area (EEA). The GDPR is an important component of EU privacy law and of human rights law, in particular Article 8(1) of the Charter of Fundamental Rights of the European Union. It also addresses the transfer of personal data outside the EU and EEA areas. The GDPR's primary aim is to enhance individuals' control and rights over their personal data and to simplify the regulatory environment for international business. Superseding the Data Protection Directive 95/46/EC, the regulation contains provisions and requirements related to the processing of personal data of individuals, formally called \"data subjects\", who are located in the EEA, and applies to any enterprise—regardless of its location and the data subjects' citizenship or residence—that is processing the personal information of individuals inside the EEA.\nThe GDPR was adopted on 14 April 2016 and became enforceable beginning 25 May 2018. As the GDPR is a regulation, not a directive, it is directly binding and applicable, and provides flexibility for certain aspects of the regulation to be adjusted by individual member states.\n\nAccording to the European Commission, \"Personal data is information that relates to an identified or identifiable individual. If you cannot directly identify an individual from that information, then you need to consider whether the individual is still identifiable. You should take into account the information you are processing together with all the means reasonably likely to be used by either you or any other person to identify that individual.\" The precise definitions of terms such as \"personal data\", \"processing\", \"data subject\", \"controller\", and \"processor\" are stated in Article 4 of the Regulation. \n\nPrinciples\nPersonal data may not be processed unless there is at least one legal basis to do so. Article 6 states the lawful purposes are:\n\n(a) If the data subject has given consent to the processing of his or her personal data;\n(b) To fulfill contractual obligations with a data subject, or for tasks at the request of a data subject who is in the process of entering into a contract;\n(c) To comply with a data controller's legal obligations;\n(d) To protect the vital interests of a data subject or another individual;\n(e) To perform a task in the public interest or in official authority;\n(f) For the legitimate interests of a data controller or a third party, unless these interests are overridden by interests of the data subject or her or his rights according to the Charter of Fundamental Rights (especially in the case of children).\n\nSecurity of personal data\nControllers and processors of personal data must put in place appropriate technical and organizational measures to implement the data protection principles. Business processes that handle personal data must be designed and built with consideration of the principles and provide safeguards to protect data (for example, using pseudonymization or full anonymization where appropriate). Data controllers must design information systems with privacy in mind. For instance, using the highest-possible privacy settings by default, so that the datasets are not publicly available by default and cannot be used to identify a subject. No personal data may be processed unless this processing is done under one of the six lawful bases specified by the regulation (consent, contract, public task, vital interest, legitimate interest or legal requirement). When the processing is based on consent the data subject has the right to revoke it at any time.\n\nArticle 33 states the data controller is under a legal obligation to notify the supervisory authority without undue delay unless the breach is unlikely to result in a risk to the rights and freedoms of the individuals. There is a maximum of 72 hours after becoming aware of the data breach to make the report. Individuals have to be notified if a high risk of an adverse impact is determined (Article 34). In addition, the data processor will have to notify the controller without undue delay after becoming aware of a personal data breach (Article 33). However, the notice to data subjects is not required if the data controller has implemented appropriate technical and organisational protection measures that render the personal data unintelligible to any person who is not authorised to access it, such as encryption (Article 34).\n\nData protection officer\n\nArticle 37 requires appointment of a data protection officer. If processing is carried out by a public authority (except for courts or independent judicial authorities when acting in their judicial capacity), or if processing operations involve regular and systematic monitoring of data subjects on a large scale, or if processing on a large scale of special categories of data and personal data relating to criminal convictions and offences (Articles 9 and Article 10) a data protection officer (DPO)—a person with expert knowledge of data protection law and practices—must be designated to assist the controller or processor in monitoring their internal compliance with the Regulation.\n\nA designated DPO can be a current member of staff of a controller or processor, or the role can be outsourced to an external person or agency through a service contract. In any case, the processing body must make sure that there is no conflict of interest in other roles or interests that a DPO may hold. The contact details for the DPO must be published by the processing organisation (for example, in a privacy notice) and registered with the supervisory authority.\n\nThe DPO is similar to a compliance officer and is also expected to be proficient at managing IT processes, data security (including dealing with cyberattacks) and other critical business continuity issues associated with the holding and processing of personal and sensitive data. The skill set required stretches beyond understanding legal compliance with data protection laws and regulations. The DPO must maintain a living data inventory of all data collected and stored on behalf of the organization. More details on the function and the role of data protection officer were given on 13 December 2016 (revised 5 April 2017) in a guideline document.\n\nOrganisations based outside the EU must also appoint an EU-based person as a representative and point of contact for their GDPR obligations (Article 27). This is a distinct role from a DPO, although there is overlap in responsibilities that suggest that this role can also be held by the designated DPO.",
        "answer": "General Data Protection Regulation provides guidelines on storing and processing personal data.

Within this cycle there are two main profiles that deal with processing personal data:\n\nThe data controller - decides the purpose and way in which personal data is processed.\nThe data processor - holds and processes data on behalf of a data controller.\nWho monitors how personal data is processed within a company?\nThe Data Protection Officer (DPO), who may have been designated by the company, is responsible for monitoring how personal data is processed and to inform and advise employees who process personal data about their obligations. The DPO also cooperates with the Data Protection Authority (DPA), serving as a contact point towards the DPA and individuals.\n\nProcessing data for another company\nA data controller can only use a data processor who offers sufficient guarantees, these should be included in a written contract between the parties involved. The contract must also contain a number of mandatory clauses, e.g. that the data processor will only process personal data when instructed to do so by the data controller.\n\nData transfer outside the EU\nWhen personal data is transferred outside the EU, the protection offered by the GDPR should travel with the data. This means that if you export data abroad, your company must ensure one of the following measures are adhered to:\n\nThe non-EU country's protections are deemed adequate by the EU.\nYour company takes the necessary measures to provide appropriate safeguards, such as including specific clauses in the agreed contract with the non-European importer of the personal data.\nYour company relies on specific grounds for the transfer (derogations) such as the consent of the individual.\nWhen is data processing allowed?\nEU data protection rules mean you should process data in a fair and lawful manner, for a specified and legitimate purpose and only process the data necessary to fulfil this purpose. You must ensure that you fulfil one of the following conditions to process the personal data; you:\n\nhave been given the consent of the individual concerned\nneed the personal data to fulfil a contractual obligation with the individual\nneed the personal data to satisfy a legal obligation\nneed the personal data to protect the vital interests of the individual\nprocess personal data to carry out the task in the interest of the public\nare acting in your company's legitimate interests, as long as the fundamental rights and freedoms of the individual whose data are processed are not seriously impacted. If the person's rights override your company's interests, then you cannot process the personal data.\n\n\nAgreeing to data processing - consent\nRight to access and right to data portability\nRight to correct and right to object\nRight to erasure (right to be forgotten)\nAutomated decision-making and profiling\nData breaches – providing proper notification\nResponding to requests\nImpact assessments\nKeeping a record",

Specifically, NLP tasks applied to well structured documents and queries can help physicians extract appropriate information to identify the best available evidence in the context of medical treatment.\nClinical questions are formed using the PIO framework, where clinical issues are broken down into four components: Population/Problem (P), Intervention (I), Comparator (C), and Outcome (O). We will refer to these categories as PIO elements, by using the common practice of merging the C and I categories. In BIBREF3 a literature screening performed in 10 systematic reviews was studied. It was found that using the PIO framework can significantly improve literature screening efficacy. Therefore, efficient extraction of PIO elements is a key feature of many EBM applications and could be thought of as a multi-label sentence classification problem.\nPrevious works on PIO element extraction focused on classical NLP methods, such as Naive Bayes (NB), Support Vector Machines (SVM) and Conditional Random Fields (CRF) BIBREF4 , BIBREF5 . These models are shallow and limited in terms of modeling capacity. Furthermore, most of these classifiers are trained to extract PIO elements one by one which is sub-optimal since this approach does not allow the use of shared structure among the individual classifiers.\nDeep neural network models have increased in popularity in the field of NLP. They have pushed the state of the art of text representation and information retrieval. More specifically, these techniques enhanced NLP algorithms through the use of contextualized text embeddings at word, sentence, and paragraph levels BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 .\nMore recently, jin2018pico proposed a bidirectional long short term memory (LSTM) model to simultaneously extract PIO components from PubMed abstracts. To our knowledge, that study was the first in which a deep learning framework was used to extract PIO elements from PubMed abstracts.\nIn the present paper, we build a dataset of PIO elements by improving the methodology found in BIBREF12 . Furthermore, we built a multi-label PIO classifier, along with a boosting framework, based on the state of the art text embedding, BERT. This embedding model has been proven to offer a better contextualization compared to a bidirectional LSTM model BIBREF9 .\nIt was found that using the PIO framework can significantly improve literature screening efficacy.",

        "question": "Please give me a list of qualities that make the Masters is golf's top tournament unique?",
        "evidence": "The Masters is the first major championship of the year. Since 1948, its final round has been scheduled for the second Sunday of April, with several exceptions.\n\nThe Masters has the smallest field of the four golf major championships.\n\nThe Masters is an invitation only tournament.\n\nPrevious Champions are eligible to play for life.",
        "answer": "As with the other majors, winning the Masters gives a golfer several privileges which make his career more secure. Masters champions are automatically invited to play in the other three majors (the U.S. Open, The Open Championship, and the PGA Championship) for the next five years (except for amateur winners, unless they turn pro within the five-year period), and earn a lifetime invitation to the Masters. They also receive membership on the PGA Tour for the following five seasons and invitations to The Players Championship for five years.\n\nBecause the tournament was established by an amateur champion, Bobby Jones, the Masters has a tradition of honoring amateur golf. It invites winners of the most prestigious amateur tournaments in the world. Also, the current U.S. Amateur champion always plays in the same group as the defending Masters champion for the first two days of the tournament.\n\nAmateurs in the field are welcome to stay in the \"Crow's Nest\" atop the Augusta National clubhouse during the tournament. The Crow's Nest is 1,200 square feet (110 m2) with lodging space for five during the competition.\n\nThe total prize money for the 2021 Masters Tournament was $11,500,000, with $2,070,000 going to the winner. In the inaugural year of 1934, the winner Horton Smith received $1,500 out of a $5,000 purse. After Nicklaus's first win in 1963, he received $20,000, while after his final victory in 1986 he won $144,000. In recent years the purse has grown quickly. Between 2001 and 2014, the winner's share grew by $612,000, and the purse grew by $3,400,000.\n\nGreen jacket\nIn addition to a cash prize, the winner of the tournament is presented with a distinctive green jacket, formally awarded since 1949 and informally awarded to the champions from the years prior. The green sport coat is the official attire worn by members of Augusta National while on the club grounds; each Masters winner becomes an honorary member of the club. The recipient of the green jacket has it presented to him inside the Butler Cabin soon after the end of the tournament in a televised ceremony, and the presentation is then repeated outside near the 18th green in front of the patrons. Winners keep their jacket for the year after their victory, then return it to the club to wear whenever they are present on the club grounds. Sam Snead was the first Masters champion to be awarded the green jacket after he took his first Masters title in 1949.\n\nThe green jacket is only allowed to be removed from the Augusta National grounds by the reigning champion, after which it must remain at the club. Exceptions to this rule include Gary Player, who in his joy of winning mistakenly took his jacket home to South Africa after his 1961 victory (although he has always followed the spirit of the rule and has never worn the jacket); Seve Ballesteros who, in an interview with Peter Alliss from his home in Pedreña, showed one of his two green jackets in his trophy room; and Henry Picard, whose jacket was removed from the club before the tradition was well established, remained in his closet for a number of years, and is now on display at Canterbury Golf Club in Beachwood, Ohio, where he was the club professional for many years.\n\nBy tradition, the winner of the previous year's Masters Tournament puts the jacket on the current winner at the end of the tournament. In 1966, Jack Nicklaus became the first player to win in consecutive years and he donned the jacket himself. When Nick Faldo (in 1990) and Tiger Woods (in 2002) repeated as champions, the chairman of Augusta National put the jacket on them.\n\nIn addition to the green jacket, winners of the tournament receive a gold medal. In 2017, a green jacket that was found at a thrift store in 1994 was sold at auction for $139,000.\n\nThere are several awards presented to players who perform exceptional feats during the tournament. The player who has the daily lowest score receives a crystal vase, while players who score a hole-in-one or a double eagle win a large crystal bowl. For each eagle a player makes, they receive a pair of crystal goblets.",

        "question": "Is their model a generative model or a discriminative model?",
        "answer": "A new generative model.",
        "evidence": "Data annotation is a major bottleneck for the application of supervised learning approaches to many problems. As a result, unsupervised methods that learn directly from unlabeled data are increasingly important. For tasks related to unsupervised syntactic analysis, discrete generative models have dominated in recent years – for example, for both part-of-speech (POS) induction BIBREF0 , BIBREF1 and unsupervised dependency parsing BIBREF2 , BIBREF3 , BIBREF4 . While similar models have had success on a range of unsupervised tasks, they have mostly ignored the apparent utility of continuous word representations evident from supervised NLP applications BIBREF5 , BIBREF6 . In this work, we focus on leveraging and explicitly representing continuous word embeddings within unsupervised models of syntactic structure.\nPre-trained word embeddings from massive unlabeled corpora offer a compact way of injecting a prior notion of word similarity into models that would otherwise treat words as discrete, isolated categories. However, the specific properties of language captured by any particular embedding scheme can be difficult to control, and, further, may not be ideally suited to the task at hand. For example, pre-trained skip-gram embeddings BIBREF7 with small context window size are found to capture the syntactic properties of language well BIBREF8 , BIBREF9 . However, if our goal is to separate syntactic categories, this embedding space is not ideal – POS categories correspond to overlapping interspersed regions in the embedding space, evident in Figure SECREF4 .\nIn our approach, we propose to learn a new latent embedding space as a projection of pre-trained embeddings (depicted in Figure SECREF5 ), while jointly learning latent syntactic structure – for example, POS categories or syntactic dependencies. To this end, we introduce a new generative model (shown in Figure FIGREF6 ) that first generates a latent syntactic representation (e.g. a dependency parse) from a discrete structured prior (which we also call the “syntax model”), then, conditioned on this representation, generates a sequence of latent embedding random variables corresponding to each word, and finally produces the observed (pre-trained) word embeddings by projecting these latent vectors through a parameterized non-linear function. The latent embeddings can be jointly learned with the structured syntax model in a completely unsupervised fashion.\nBy choosing an invertible neural network as our non-linear projector, and then parameterizing our model in terms of the projection's inverse, we are able to derive tractable exact inference and marginal likelihood computation procedures so long as inference is tractable in the underlying syntax model. In sec:learn-with-inv we show that this derivation corresponds to an alternate view of our approach whereby we jointly learn a mapping of observed word embeddings to a new embedding space that is more suitable for the syntax model, but include an additional Jacobian regularization term to prevent information loss.\nRecent work has sought to take advantage of word embeddings in unsupervised generative models with alternate approaches BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . BIBREF9 build an HMM with Gaussian emissions on observed word embeddings, but they do not attempt to learn new embeddings. BIBREF10 , BIBREF11 , and BIBREF12 extend HMM or dependency model with valence (DMV) BIBREF2 with multinomials that use word (or tag) embeddings in their parameterization. However, they do not represent the embeddings as latent variables.\nIn experiments, we instantiate our approach using both a Markov-structured syntax model and a tree-structured syntax model – specifically, the DMV. We evaluate on two tasks: part-of-speech (POS) induction and unsupervised dependency parsing without gold POS tags. Experimental results on the Penn Treebank BIBREF13 demonstrate that our approach improves the basic HMM and DMV by a large margin, leading to the state-of-the-art results on POS induction, and state-of-the-art results on unsupervised dependency parsing in the difficult training scenario where neither gold POS annotation nor punctuation-based constraints are available.\n\nTo this end, we introduce a new generative model (shown in Figure 2) that first generates a latent syntactic representation (e.g. a dependency parse) from a discrete structured prior (which we also call the “syntax model”), then, conditioned on this representation, generates a sequence of latent embedding random variables corresponding to each word, and finally produces the observed (pre-trained) word embeddings by projecting these latent vectors through a parameterized non-linear function.",

        "evidence": "The used architecture of the QA model is briefly summarized below. Here we choose QANet BIBREF2 as the base model due to the following reasons: 1) it achieves the second best performance on SQuAD, and 2) since there are completely no recurrent networks in QANet, its training speed is 5x faster than BiDAF BIBREF17 when reaching the same performance on SQuAD.\nThe network architecture is illustrated in Figure FIGREF2 . The left blocks and the right blocks form two QANets, each of which takes a document and a question as the input and outputs an answer. In QANet, firstly, an embedding encoder obtains word and character embeddings for each word in INLINEFORM0 or INLINEFORM1 and then models the temporal interactions between words and refines word vectors to contextualized word representations. All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention. The intuition here is that convolution components can model local interactions and self-attention components focus on modeling global interactions. The context-query attention layer generates the question-document similarity matrix and computes the question-aware vector representations of the context words. After that, a model encoder layer containing seven encoder blocks captures the interactions among the context words conditioned on the question. Finally, the output layer predicts a start position and an end position in the document to extract the answer span from the document.\nHere we choose QANet [3] as the base model due to the following reasons: 1) it achieves the second best performance on SQuAD, and 2) since there are completely no recurrent networks in QANet, its training speed is 5x faster than BiDAF [18] when reaching the same performance on SQuAD.",

        "question": "Which models are superior in generating fluent and grammatical questions, rule-based approaches or neural models?",
        "answer": "Neural models.",
        "evidence": "The topic of question generation, initially motivated for educational purposes, is tackled by designing many complex rules for specific question types BIBREF4, BIBREF23. Heilman2010GoodQS improve rule-based question generation by introducing a statistical ranking model. First, they remove extraneous information in the sentence to transform it into a simpler one, which can be transformed easily into a succinct question with predefined sets of general rules. Then they adopt an overgenerate-and-rank approach to select the best candidate considering several features.\nWith the rise of dominant neural sequence-to-sequence learning models BIBREF5, Du2017LearningTA frame question generation as a sequence-to-sequence learning problem. Compared with rule-based approaches, neural models BIBREF24 can generate more fluent and grammatical questions. However, question generation is a one-to-many sequence generation problem, i.e., several aspects can be asked given a sentence, which confuses the model during train and prevents concrete automatic evaluation. To tackle this issue, Zhou2017NeuralQG propose the answer-aware question generation setting which assumes the answer is already known and acts as a contiguous span inside the input sentence. They adopt a BIO tagging scheme to incorporate the answer position information as learned embedding features in Seq2Seq learning. Song2018LeveragingCI explicitly model the information between answer and sentence with a multi-perspective matching model. Kim2019ImprovingNQ also focus on the answer information and proposed an answer-separated Seq2Seq model by masking the answer with special tokens. All answer-aware neural models treat question generation as a one-to-one mapping problem, but existing models perform poorly for sentences with a complex structure (as shown in Table TABREF2).\nOur work is inspired by the process of extraneous information removing in BIBREF0, BIBREF25. Different from Heilman2010GoodQS which directly use the simplified sentence for generation and cao2018faithful which only consider aggregate two sources of information via gated attention in summarization, we propose to combine the structured answer-relevant relation and the original sentence. Factoid question generation from structured text is initially investigated by Serban2016GeneratingFQ, but our focus here is leveraging structured inputs to help question generation over unstructured sentences. Our proposed model can take advantage of unstructured sentences and structured answer-relevant relations to maintain informativeness and faithfulness of generated questions. The proposed model can also be generalized in other conditional sequence generation tasks which require multiple sources of inputs, e.g., distractor generation for multiple choice questions BIBREF26.\nCompared with rule-based approaches, neural models (Yuan et al., 2017) can generate more fluent and grammatical questions.",

        "evidence": "The Panama Canal is an artificial 82 km (51 mi) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan.\n\nColombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the project on May 4, 1904, and opened the canal on August 15, 1914. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for its handover to Panama. After a period of joint American–Panamanian control, the canal was taken over by the Panamanian government in 1999. It is now managed and operated by the government-owned Panama Canal Authority.\n\nCanal locks at each end lift ships up to Gatun Lake, an artificial lake 26 meters (85 ft) above sea level, created to reduce the amount of excavation work required for the canal, and then lower the ships at the other end. The original locks are 33.5 meters (110 ft) wide. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded waterway began commercial operation on June 26, 2016. The new locks allow transit of larger, New Panamax ships.\n\nAnnual traffic has risen from about 1,000 ships in 1914, when the canal opened, to 14,702 vessels in 2008, for a total of 333.7 million Panama Canal/Universal Measurement System (PC/UMS) tons. By 2012, more than 815,000 vessels had passed through the canal. In 2017 it took ships an average of 11.38 hours to pass between the canal's two locks.

        "evidence": "In June 2015, the operators of the online discussion site Reddit banned several communities under new anti-harassment rules. BIBREF0 used this opportunity to combine rich online data with computational methods to study a current question: Does eliminating these “echo chambers” diminish the amount of hate speech overall? Exciting opportunities like these, at the intersection of “thick” cultural and societal questions on the one hand, and the computational analysis of rich textual data on larger-than-human scales on the other, are becoming increasingly common.\nIndeed, computational analysis is opening new possibilities for exploring challenging questions at the heart of some of the most pressing contemporary cultural and social issues. While a human reader is better equipped to make logical inferences, resolve ambiguities, and apply cultural knowledge than a computer, human time and attention are limited. Moreover, many patterns are not obvious in any specific context, but only stand out in the aggregate. For example, in a landmark study, BIBREF1 analyzed the authorship of The Federalist Papers using a statistical text analysis by focusing on style, based on the distribution of function words, rather than content. As another example, BIBREF2 studied what defines English haiku and showed how computational analysis and close reading can complement each other. Computational approaches are valuable precisely because they help us identify patterns that would not otherwise be discernible.\nYet these approaches are not a panacea. Examining thick social and cultural questions using computational text analysis carries significant challenges. For one, texts are culturally and socially situated. They reflect the ideas, values and beliefs of both their authors and their target audiences, and such subtleties of meaning and interpretation are difficult to incorporate in computational approaches. For another, many of the social and cultural concepts we seek to examine are highly contested — hate speech is just one such example. Choices regarding how to operationalize and analyze these concepts can raise serious concerns about conceptual validity and may lead to shallow or obvious conclusions, rather than findings that reflect the depth of the questions we seek to address.\nThese are just a small sample of the many opportunities and challenges faced in computational analyses of textual data. New possibilities and frustrating obstacles emerge at every stage of research, from identification of the research question to interpretation of the results. In this article, we take the reader through a typical research process that involves measuring social or cultural concepts using computational methods, discussing both the opportunities and complications that often arise. In the Reddit case, for example, hate speech is measured, however imperfectly, by the presence of particular words semi-automatically extracted from a machine learning algorithm. Operationalizations are never perfect translations, and are often refined over the course of an investigation, but they are crucial.\nWe begin our exploration with the identification of research questions, proceed through data selection, conceptualization, and operationalization, and end with analysis and the interpretation of results. The research process sounds more or less linear this way, but each of these phases overlaps, and in some instances turns back upon itself. The analysis phase, for example, often feeds back into the original research questions, which may continue to evolve for much of the project. At each stage, our discussion is critically informed by insights from the humanities and social sciences, fields that have focused on, and worked to tackle, the challenges of textual analysis—albeit at smaller scales—since their inception.\nIn describing our experiences with computational text analysis, we hope to achieve three primary goals. First, we aim to shed light on thorny issues not always at the forefront of discussions about computational text analysis methods. Second, we hope to provide a set of best practices for working with thick social and cultural concepts. Our guidance is based on our own experiences and is therefore inherently imperfect. Still, given our diversity of disciplinary backgrounds and research practices, we hope to capture a range of ideas and identify commonalities that will resonate for many. And this leads to our final goal: to help promote interdisciplinary collaborations. Interdisciplinary insights and partnerships are essential for realizing the full potential of any computational text analysis that involves social and cultural concepts, and the more we are able to bridge these divides, the more fruitful we believe our work will be.\nWe begin our exploration with the identification of research questions, proceed through data selection, conceptualization, and operationalization, and end with analysis and the interpretation of results.",

        "answer": "Robin Lakoff, who argued that language is fundamental to gender inequality, “reflected in both the ways women are expected to speak, and the ways in which women are spoken of”.",
        "evidence": "The study of gender and language has a rich history in social science. Its roots are often attributed to Robin Lakoff, who argued that language is fundamental to gender inequality, “reflected in both the ways women are expected to speak, and the ways in which women are spoken of” BIBREF2. Prominent scholars following Lakoff have included Deborah Tannen BIBREF3, Mary Bucholtz and Kira Hall BIBREF4, Janet Holmes BIBREF5, Penelope Eckert BIBREF6, and Deborah Cameron BIBREF7, along with many others.\nIn recent decades, the study of gender and language has also attracted computational researchers. Echoing Lakoff's original claim, a popular strand of computational work focuses on differences in how women and men talk, analyzing key lexical traits BIBREF8, BIBREF9, BIBREF10 and predicting a person's gender from some text they have written BIBREF11, BIBREF12. There is also research studying how people talk to women and men BIBREF13, as well as how people talk about women and men, typically in specific domains such as sports journalism BIBREF14, fiction writing BIBREF15, movie scripts BIBREF16, and Wikipedia biographies BIBREF17, BIBREF18. Our work builds on this body by diving into two novel domains: celebrity news, which explores gender in pop culture, and student reviews of CS professors, which examines gender in academia and, particularly, the historically male-dominated field of CS. Furthermore, many of these works rely on manually constructed lexicons or topics to pinpoint gendered language, but our methods automatically infer gender-associated words and labeled clusters, thus reducing supervision and increasing the potential to discover subtleties in the data.\nModeling gender associations in language could also be instrumental to other NLP tasks. Abusive language is often founded in sexism BIBREF0, BIBREF1, so models of gender associations could help to improve detection in those cases. Gender bias also manifests in NLP pipelines: prior research has found that word embeddings preserve gender biases BIBREF19, BIBREF20, BIBREF21, and some have developed methods to reduce this bias BIBREF22, BIBREF23. Yet, the problem is far from solved; for example, BIBREF24 showed that it is still possible to recover gender bias from “de-biased” embeddings. These findings further motivate our research, since before we can fully reduce gender bias in embeddings, we need to develop a deeper understanding of how gender permeates through language in the first place.\nWe also build on methods to cluster words in word embedding space and automatically label clusters. Clustering word embeddings has proven useful for discovering salient patterns in text corpora BIBREF25, BIBREF26. Once clusters are derived, we would like them to be interpretable. Much research simply considers the top-n words from each cluster, but this method can be subjective and time-consuming to interpret. Thus, there are efforts to design methods of automatic cluster labeling BIBREF27. We take a similar approach to BIBREF28, who leverage word embeddings and WordNet during labeling, and we extend their method with additional techniques and evaluations.\nThe study of gender and language has a rich history in social science. Its roots are often attributed to Robin Lakoff, who argued that language is fundamental to gender inequality, “reflected in both the ways women are expected to speak, and the ways in which women are spoken of” (Lakoff, 1973).",

        "answer": "(a) They need to effectively model the contextual usages of entities and relations. (b) They would need to be useful for a variety of predictive tasks on knowledge graphs.",
        "evidence": "Knowledge graphs BIBREF0 enable structured access to world knowledge and form a key component of several applications like search engines, question answering systems and conversational assistants. Knowledge graphs are typically interpreted as comprising of discrete triples of the form (entityA, relationX, entityB) thus representing a relation (relationX) between entityA and entityB. However, one limitation of only a discrete representation of triples is that it does not easily enable one to infer similarities and potential relations among entities which may be missing in the knowledge graph. Consequently, one popular alternative is to learn dense continuous representations of entities and relations by embedding them in latent continuous vector spaces, while seeking to model the inherent structure of the knowledge graph. Most knowledge graph embedding methods can be classified into two major classes: one class which operates purely on triples like RESCAL BIBREF1 , TransE BIBREF2 , DistMult BIBREF3 , TransD BIBREF4 , ComplEx BIBREF5 , ConvE BIBREF6 and the second class which seeks to incorporate additional information (like multi-hops) BIBREF7 . Learning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.\nIn this paper, we present a new type of knowledge graph embeddings called Dolores that are both deep and contextualized. Dolores learns both context-independent and context-dependent embeddings of entities and relations through a deep neural sequential model. Figure 1 illustrates the deep contextualized representations learned. Note that the contextually independent entity embeddings (see Figure 1 ) reveal three clusters of entities: writers, philosophers, and musicians. The contextual dependent embeddings in turn effectively account for specific relations. In particular, the context-dependent representations under the relation nationality now nicely cluster the above entities by nationality namely Austrians, Germans, and British/Irish. Similarly Figure 1 shows contextual embeddings given the relation place-lived. Note that these embeddings correctly capture that even though Beethoven and Brahms being Germans, they lived in Vienna and are closer to other Austrian musicians like Schubert.\nUnlike most knowledge graph embeddings like TransD, TransE BIBREF2 , BIBREF4 etc. which are typically learned using shallow models, the representations learned by Dolores are deep: dependent on an entire path (rather than just a triple), are functions of internal states of a Bi-Directional LSTM and composed of representations learned at various layers potentially capturing varying degrees of abstractions. Dolores is inspired by recent advances in learning word representations (word embeddings) from deep neural language models using Bi-Directional LSTMs BIBREF8 . In particular, we derive connections between the work of Peters et al. ( BIBREF8 ) who learn deep contextualized word embeddings from sentences using a Bi-Directional LSTM based language model and random walks on knowledge graphs. These connections enable us to propose new “deep contextualized” knowledge graph embeddings which we call Dolores embeddings.\nKnowledge Embeddings learned using Dolores can easily be used as input representations for predictive models on knowledge graphs. More importantly, when existing predictive models use input representations for entities and relations, we can easily replace those representations with Dolores representations and significantly improve the performance of existing models. Specifically, we show that Dolores embeddings advance the state-of-the-art models on various tasks like link prediction, triple classification and missing relation type prediction.\nTo summarize, our contributions are as follows:\nLearning high-quality knowledge graph embeddings can be quite challenging given that (a) they need to effectively model the contextual usages of entities and relations (b) they would need to be useful for a variety of predictive tasks on knowledge graphs.",

        "answer": "Yes.",
        "evidence": "Personalized dialogue agents have been shown efficient in conducting human-like conversation. This progress has been catalyzed thanks to existing conversational dataset such as Persona-chat BIBREF0, BIBREF1. However, the training data are provided in a single language (e.g., English), and thus the resulting systems can perform conversations only in the training language. For wide, commercial dialogue systems are required to handle a large number of languages since the smart home devices market is increasingly international BIBREF2. Therefore, creating multilingual conversational benchmarks is essential, yet challenging since it is costly to perform human annotation of data in all languages.\nA possible solution is to use translation systems before and after the model inference, a two-step translation from any language to English and from English to any language. This comes with three major problems: 1) amplification of translation errors since the current dialogue systems are far from perfect, especially with noisy input; 2) the three-stage pipeline system is significantly slower in terms of inference speed; and 3) high translation costs since the current state-of-the-art models, especially in low resources languages, are only available using costly APIs.\nIn this paper, we analyze two possible workarounds to alleviate the aforementioned challenges. The first is to build a cross-lingual transferable system by aligning cross-lingual representations, as in BIBREF3, in which the system is trained on one language and zero-shot to another language. The second is to learn a multilingual system directly from noisy multilingual data (e.g., translated data), thus getting rid of the translation system dependence at inference time.\nTo evaluate the aforementioned systems, we propose a dataset called Multilingual Persona-Chat, or XPersona, by extending the Persona-Chat corpora BIBREF1 to six languages: Chinese, French, Indonesian, Italian, Korean, and Japanese. In XPersona, the training sets are automatically translated using translation APIs with several human-in-the-loop passes of mistake correction. In contrast, the validation and test sets are annotated by human experts to facilitate both automatic and human evaluations in multiple languages.\nFurthermore, we propose competitive baselines in two training settings, namely, cross-lingual and multilingual, and compare them with translation pipeline models. Our baselines leverage pre-trained cross-lingual BIBREF4 and multilingual BIBREF5 models.\nAn extensive automatic and human evaluation BIBREF6 of our models shows that a multilingual system is able to outperform strong translation-based models and on par with or even improve the monolingual model. The cross-lingual performance is still lower than other models, which indicates that cross-lingual conversation modeling is very challenging. The main contribution of this paper are summarized as follows:\nWe present the first multilingual non-goal-oriented dialogue benchmark for evaluating multilingual generative chatbots.\nWe provide both cross-lingual and multilingual baselines and discuss their limitations to inspire future research.\nWe show the potential of multilingual systems to understand the mixed language dialogue context and generate coherent responses.\nAn extensive automatic and human evaluation of our models shows that a multilingual system is able to outperform strong translation-based models and on par with or even improve the monolingual model.",

        "answer": "Social bots and echo chambers.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nThese have shown that false news spread faster and deeper than true news (Vosoughi, Roy, and Aral 2018), and that social bots and echo chambers play an important role in the diffusion of malicious content (Shao et al. 2018a; Del Vicario et al. 2016).",

Its latter name comes from its founder, Arsaces I, who led the Parni tribe in conquering the region of Parthia in Iran's northeast, then a satrapy (province) under Andragoras, who was rebelling against the Seleucid Empire. Mithridates I (r. c. 171–132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to present-day Afghanistan and western Pakistan.

These deep networks generate contextual representations of words after been trained for extended periods on large corpora, unsupervised, using the attention mechanisms (BIBREF4).\nIt has been observed that various hyper-parameter combinations have been used in different research involving word2vec with the possibility of many of them being sub-optimal (BIBREF5, BIBREF6, BIBREF7). Therefore, the authors seek to address the research question: what is the optimal combination of word2vec hyper-parameters for intrinsic and extrinsic NLP purposes? There are astronomically high numbers of combinations of hyper-parameters possible for neural networks, even with just a few layers. Hence, the scope of our extensive work over three corpora is on dimension size, training epochs, window size and vocabulary size for the training algorithms (hierarchical softmax and negative sampling) of both skipgram and CBoW. The corpora used for word embeddings are English Wiki News Abstract by BIBREF8 of about 15MB, English Wiki Simple (SW) Articles by BIBREF9 of about 711MB and the Billion Word (BW) of 3.9GB by BIBREF10.

        "evidence": "",
        "answer": "Competition is prevalent everywhere in our society. Despite causing many people to feel stressed or pressured, competition is beneficial for challenging oneself, but it must be utilized properly.\nA common habitat of competition is in sports. Whether it be competing against another person, another team, or against time, sports push people to work harder, faster, and stronger. This athletic competition is good, because it is mutually beneficial for both parties. Both and all players are challenged physically, and thats are taught both the importance and, if they succeed, the rewards of hard work.\nCompetition in sports is expected, However, the misuse of competitiveness has become common in academics. While competition in sports is expected, academics is meant to be more reflective. Competition between students for the highest marks can be good, as both will challenge each other, but often makes other students feel belittled and unworthy. Grades in particular are a measure of self-knowledge and hard work and should not be used to compare one student to another. This is where and how competition is often misused and its intentions misunderstood.\nOften this misused competition comes from pressure from peers, parents, and sometimes teachers. A common example is competition between siblings stimulated by parents: comparing the childrens looks, academie abilities, athleticism, and social awareness. This kind of abusive competition is more likely to create anxiety, insecurity, and depression for both siblings, revealing perhaps the most important condition for healthy competition: it has to come from yourself.\nAlmost all negative experiences with competition stem from society around us, leading many to believe that the correct thing to do is compare students, siblings. children, employees, and more. But competition's true purpose is to inspiles oneself to work hard and take on new challenges. \"Forced\" competition doesn't allow a person to be in control of their goals. This is why Kohn felt \"caught on a treadmill,\" when being compared to others. The competition comes from within and motivates one to set, work for, and reach new goals.\nTo prevent unhealthy competition, people should try to be more vocal about their goals and expectations about themselves. Encouragement, of course, is always nice so voicing your wishes is important. If parents, teachers, or bosses know what you expect from yourself. they can better encourage, support, and challenge you.",

The two powers promised each other support in case of attack by Russia. Also, each state promised benevolent neutrality to the other if one of them was attacked by another European power (generally taken to be France, even more so after the Franco-Russian Alliance of 1894). Bismarck saw the alliance as a way to prevent the isolation of the German Empire, which had just been founded a few years before, and to preserve peace, as Russia would not wage war against both empires.\n\nFormation\nWhen Austria-Hungary and Germany formed an alliance in 1879, it was one of the more surprising alliances of its time. Though both shared the German language and a similar culture, Austria-Hungary and Germany were often driven apart, most notably during the recent Austro-Prussian War.

        "question": "What is employed by them for relation extraction?",
        "answer": "Both the entity embeddings and relative position embeddings.",
        "evidence": "Relation extraction (RE) is one of the most fundamental tasks in natural language processing, and its goal is to identify the relationship between a given pair of entities in a sentence. Typically, a large-scale training dataset with clean labels is required to train a reliable relation extraction model. However, it is time-consuming and labor-intensive to annotate such data by crowdsourcing. To overcome the lack of labeled training data, BIBREF0 mintz2009distant presents a distant supervision approach that automatically generates a large-scale, labeled training set by aligning entities in knowledge graph (e.g. Freebase BIBREF1) to corresponding entity mentions in natural language sentences. This approach is based on a strong assumption that, any sentence containing two entities should be labeled according to the relationship of the two entities on the given knowledge graph. However, this assumption does not always hold. Sometimes the same two entities in different sentences with various contexts cannot express a consistent relationship as described in the knowledge graph, which certainly results in wrongly labeled problem.\nTo alleviate the aformentioned problem, BIBREF2 riedel2010modeling proposes a multi-instance learning framework, which relaxes the strong assumption to expressed-at-least-one assumption. In plainer terms, this means any possible relation between two entities hold true in at least one distantly-labeled sentence rather than all of the them that contains those two entities. In particular, instead of generating a sentence-level label, this framework assigns a label to a bag of sentences containing a common entity pair, and the label is a relationship of the entity pair on knowledge graph. Recently, based on the labeled data at bag level, a line of works BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7 under selective attention framework BIBREF5 let model implicitly focus on the correctly labeled sentence(s) by an attention mechanism and thus learn a stable and robust model from the noisy data.\nHowever, such selective attention framework is vulnerable to situations where a bag is merely comprised of one single sentence labeled; and what is worse, the only one sentence possibly expresses inconsistent relation information with the bag-level label. This scenario is not uncommon. For a popular distantly supervised relation extraction benchmark, e.g., NYT dataset BIBREF2, up to $80\\%$ of its training examples (i.e., bags) are one-sentence bags. From our data inspection, we randomly sample 100 one-sentence bags and find $35\\%$ of them is incorrectly labeled. Two examples of one-sentence bag are shown in Table TABREF1. These results indicate that, in training phrase the selective attention module is enforced to output a single-valued scalar for $80\\%$ examples, leading to an ill-trained attention module and thus hurting the performance.\nMotivated by aforementioned observations, in this paper, we propose a novel Selective Gate (SeG) framework for distantly supervised relation extraction. In the proposed framework, 1) we employ both the entity embeddings and relative position embeddings BIBREF8 for relation extraction, and an entity-aware embedding approach is proposed to dynamically integrate entity information into each word embedding, yielding more expressively-powerful representations for downstream modules; 2) to strengthen the capability of widely-used piecewise CNN (PCNN) BIBREF3 on capturing long-term dependency BIBREF9, we develop a light-weight self-attention BIBREF10, BIBREF11 mechanism to capture rich dependency information and consequently enhance the capability of neural network via producing complementary representation for PCNN; and 3) based on preceding versatile features, we design a selective gate to aggregate sentence-level representations into bag-level one and alleviate intrinsic issues appearing in selective attention.\nCompared to the baseline framework (i.e., selective attention for multi-instance learning), SeG is able to produce entity-aware embeddings and rich-contextual representations to facilitate downstream aggregation modules that stably learn from noisy training data. Moreover, SeG uses gate mechanism with pooling to overcome problem occurring in selective attention, which is caused by one-sentence bags. In addition, it still keeps a light-weight structure to ensure the scalability of this model.\nThe experiments and extensive ablation studies on New York Time dataset BIBREF2 show that our proposed framework achieves a new state-of-the-art performance regarding both AUC and top-n precision metrics for distantly supervised relation extraction task, and also verify the significance of each proposed module. Particularly, the proposed framework can achieve AUC of 0.51, which outperforms selective attention baseline by 0.14 and improves previous state-of-the-art approach by 0.09.\n1) we employ both the entity embeddings and relative position embeddings (Zeng et al. 2014) for relation extraction, and an entity-aware embedding approach is proposed to dynamically integrate entity information into each word embedding, yielding more expressively-powerful representations for downstream modules;",

        "evidence": "Among neural networks, LSTMs BIBREF0 are commonly used for language modeling. Although new architectures BIBREF1, BIBREF2 challenge this standard, LSTMs remain competitive for language modeling BIBREF3. However, despite the success of LM LSTMs, it is not clear what makes them so effective. In particular, are representations derived through language modeling able to effectively encode syntactic structures and relations? Do they encode them in a reliable and systematic way?\nThe typical metric used to compare LMs, perplexity, is not adapted to address these questions. Perplexity measures the probability assigned to held-out data from the corpus the LM is trained on. Because the held-out and training data are typically randomly extracted from an initial corpus, they have similar statistics, which is good from a machine learning viewpoint, but bad from the viewpoint of linguistic analysis: perplexity is mostly sensitive to the most common sentence types in the initial corpus and therefore will not reflect well the behavior of the LM in the tail of the distribution. In addition, the sentences extracted from a natural corpus confound several factors: syntax, semantics, pragmatics, etc. further complicating the interpretation of a good perplexity score.\nTo circumvent this limitation, recent work has focused on using probing techniques inspired by linguistic and psycholinguistics (for instance, grammaticality or acceptability judgments, or forced choice). In addition, instead of using sentences from the training corpus, studies rely more and more on automatically constructed test sentences, which enable for a removal of the bias in the original corpus and focus on particular linguistic phenomena. Here, we will use acceptability judgments operationalized by the log probability of sentences according to the LM and sets of synthetic sentences generated from template sentences to probe for a challenging linguistic structure: verb argument structure.\nVerb argument structure provides languages with a way to link syntactic position in a sentence (subject, direct object, etc) with semantic roles (agent, patient, etc), in other words, to determine who is doing what. It is currently unknown whether neural LMs purely trained from surface statistics are able to capture this kind of structure, or whether additional information from another modality would be needed to provide some semantic grounding.\nVerb argument structure is typically correlated to sentence position in many languages like English. But in other languages with relatively free word order, it is indicated by morphological markers. Here, we study German, where the arguments of a verb can occur in any position (when occurring within a relative clause), and is indicated by the case of the noun phrase (nominative, accusative, etc).\nWe setup a test of argument structure representation by presenting a trained LM with carefully constructed sets of sentences that either have the right set of arguments, or abnormal sentences where one case is missing or duplicated. We use word order permutations to control for unigram and positional statistics. If the LM is able to track argument structure irrespective of word order, it should assign lower grammaticality scores (log probabilities) to the incorrect sentences as compared to the correct ones.\nSince at the level of the sentence, we study a global rather than local syntactic phenomenon, we depart from earlier work BIBREF4, BIBREF5, BIBREF6, BIBREF7 and do not compare pairs of sentences. Rather, we compare a set of valid grammatical variations of the template to a corresponding set of grammatical violations of the template. Thus, for each template, we measure the model's ability to discriminate grammatical sentences from ungrammatical ones using receiver operating characteristic curves, or ROC curves. We also compute the area under the ROC curve, or AUC. In our results, we often report the average AUC over templates as our metric.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus. We ask proficient German speakers to annotate our sentences for grammaticality, providing a human comparison. Since some of these sentences are rather implausible because of the permutations, we also collect human meaningfulness scores. We find that our dataset is challenging for both LMs and humans and that LMs lag behind human performance.\nWe evaluate three LMs on our dataset, the two-layer LSTM of BIBREF8 trained on German Wikipedia text, as well as n-gram baselines using the same corpus.",

[1] shows significant improvement in performance on both ImageNet-C and ImageNet-R (both out of distribution datasets). Also, smoothness in image space has been shown to be beneficial for domain adaptation [2]. We aim to explore the smoothness in weight space and its effect on domain adaptation in this current work.",
        "evidence": "Unsupervised Domain Adaptation: It refers to a class of methods that aim to adapt models to work in a target domain distinct from what it was trained on. One of the most prominent lines of work is based on DAT. This involves using an additional discriminator to distinguish between samples of source and target domain. The goal of the model is to learn features that can not be distinguished between source and target. The follow-up works have improved this basic idea by introducing a class information based discriminator (CDAN), introducing a transferable normalization function  etc. In this work, we focus on analyzing and improving such methods. Another line of work involves DA by using self-training on target domain which will not be the focus of this work.\nAs neural networks operate in the regime of over parameterized models, low error on training data does not always lead to better generalization . Often it has been stated) that smoother minima does generalize better on unseen data. But until recently, this was practically expensive as smoothing required additional costly computations. Recently, a method called Sharpness Aware Minimization (SAM) has been proposed to find a smoother minima with an additional gradient computation step. SAM also improves the ImageNet model performance on ImageNet-C and ImageNet-R (which are out of distribution). It has also been observed that smoothness w.r.t. input (image) is beneficial for domain adaptation, which motivates us to explore smoothness w.r.t weights (W) in case of DAT. However, the earlier work has focused on achieving a smoother minima w.r.t. W for ERM. Currently, no study has been done if the loss function is composed of both ERM and adversarial objectives (as present in DAT).\nSAM also improves the ImageNet model performance (Chen et al., 2021) on ImageNet-C and ImageNet-R (which are out of distribution).

        "evidence": "The National Association of Broadcasters (NAB) is a trade association and lobby group representing the interests of commercial and non-commercial over-the-air radio and television broadcasters in the United States. The NAB represents more than 8,300 terrestrial radio and television stations as well as broadcast networks.\n\nAs of 2022, the president and CEO of the NAB is Curtis LeGeyt.\n\nFounding\n\nNAB headquarters in Washington, D.C.\nThe NAB was founded as the National Association of Radio Broadcasters (NARB) in April 1923 at the Drake Hotel in Chicago. The association's founder and first president was Eugene F. McDonald Jr., who also launched the Zenith corporation. In 1951 it changed its name to the National Association of Radio and Television Broadcasters (NARTB) to include the television industry. In 1958 it adopted its current name, \"National Association of Broadcasters\".\n\nCommercial radio\nThe NAB worked to establish a commercial radio system in the United States. The system was set up in August 1928 with the establishment of General Order 40—a radio reallocation scheme by the Federal Radio Commission which awarded the choicest frequencies and broadcast times to the then-emerging commercial radio industry. In the wake of General Order 40, a loose coalition of educators, nonprofit broadcasters, labor unions, and religious groups coalesced to oppose the NAB and their allies through the 1920s and 1930s, and to develop a public, nonprofit, license-funded radio system without commercials (similar to what happened with the BBC). The coalition claimed that the commercial industry would only promote profitable programming, thereby reducing the quality and future potential of radio broadcasting.\n\nNot having the political connections, resources, or publicity of the NAB and the commercial radio industry, the non-profit coalition eventually lost the fight with the passage of the Communications Act of 1934.\n\nThe National Independent Broadcasters were formed in 1939 as part of the NAB, to represent stations that were not associated with any network, but the group split off in 1941.\n\nSatellite radio\nMany satellite radio enthusiasts have criticized the NAB for lobbying against legislation approvals for those services. The NAB protested the FCC's approval of both satellite radio services in the United States—XM and Sirius—and furthermore criticized the 2008 merger of the two companies, calling the merged company a \"potential monopoly\".\n\nDigital transition\nIn 2005, the NAB, together with the Association for Maximum Service Television Stations, Inc. (MSTV), commenced development of a prototype high quality, low cost digital-to-analog converter box for terrestrial digital television reception. The result of this project was a specification for the converter box, which was then adopted by the National Telecommunications and Information Administration as a technical requirement for eligible converter boxes for the Administration's Digital-to-Analog Converter Box Coupon Program.\n\nWhite space\nThe NAB has lobbied against the use of white spaces, unused broadcast spectrum lying between broadcast channels, for wireless broadband internet and other digital use. The NAB has claimed that use of white space will interfere with existing broadcast spectrum, even though tests by the Federal Communications Commission at levels far stronger than that being advocated for in policy circles have not supported such claims. Indeed, the FCC has recommended the use of white spaces for broadband and other digital use. In 2011 the NAB funded an advertising campaign titled \"The Future of TV\", advocating for the private ownership of the spectrum, framed as a threat to free television.\n\nFree TV campaign\nIn mid-2014, an NAB advertising campaign against a Congressional threat appeared, advocating viewers to defeat a cable-TV lobby.\n\nSimilar organizations\nOrganizations similar to the NAB exist in individual U.S. states, including Georgia Association of Broadcasters (GAB) in Georgia, and the Illinois Broadcasters Association (IBA), in Illinois. In Canada, the Canadian Association of Broadcasters (CAB) has a similar role.",

The team played at Rabobank Arena until 2009 and later at the Jam Events Center.

On April 12, 2016, the Suns announced that the organization had purchased the Jam and were relocating the franchise to the town of Prescott Valley, Arizona, for the 2016–17 season to become the Northern Arizona Suns.

        "evidence": "Wikipedia is the largest source of open and collaboratively curated knowledge in the world. Introduced in 2001, it has evolved into a reference work with around 5m pages for the English Wikipedia alone. In addition, entities and event pages are updated quickly via collaborative editing and all edits are encouraged to include source citations, creating a knowledge base which aims at being both timely as well as authoritative. As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page. However, not all information sources are equal. The online presence of major news outlets is an authoritative source due to active editorial control and their articles are also a timely container of facts. In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them). However, such an approach lacks in (a) reproducibility since rankings vary with time with obvious bias to recent news (b) maintainability since document acquisition for each entity has to be periodically performed. To this effect, our news suggestion considers a news article as input, and determines if it is valuable for Wikipedia. Specifically, given an input news article INLINEFORM0 and a state of Wikipedia, the news suggestion problem identifies the entities mentioned in INLINEFORM1 whose entity pages can improve upon suggesting INLINEFORM2 . Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower. Third, a good recommendation should be able to identify novel news by minimizing redundancy coming from multiple news articles. Finally, addition of facts is facilitated if the recommendations are fine-grained, i.e., recommendations are made on the section level rather than the page level (placement).\nApproach and Contributions. We propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity's salience in the news article, its relative authority and the novelty of the article to the entity page. The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years. The existing news references in the entity pages along with their reference date act as our ground-truth to evaluate our approach. In summary, we make the following contributions.\nIn summary, we make the following contributions. • we propose a two-stage news suggestion approach for Wikipedia entity pages. • we adopt and address the problem of determining whether a news article should be referenced to an entity considering the entity salience, relative authority and novelty of the article for the entity page. • we are able to place articles in a specific section of the entity page. Through section templates, we address the problems of entities with a limited section structure by class-based generalization i.e. we can expand entity pages with sections that come from entities of a similar class. • an extensive evaluation on 351,982 news articles and 73,734 entity pages, using their state for the years [2009-2013].",

        "answer": "The descriptions are sometimes confusing and unnatural to native people.",
        "evidence": "Generating descriptions for multimedia contents such as images and videos, so called Image Captioning, is helpful for e-commerce companies or news agencies. For instance, in e-commerce field, people will no longer need to put much effort into understanding and describing products' images on their websites because image contents can be recognized and descriptions are automatically generated. Inspired by Horus BIBREF0 , Image Captioning system can also be integrated into a wearable device, which is able to capture surrounding images and generate descriptions as sound in real time to guide people with visually impaired.\nImage Captioning has attracted attentions from researchers in recent years BIBREF1, BIBREF2, BIBREF3, and there has been promising attempts dealing with language barrier in this task by extending existed dataset captions into different languages BIBREF3, BIBREF4.\nIn this study, generating image captions in Vietnamese language is put into consideration. One straightforward approach for this task is to translate English captions into Vietnamese by human or by using machine translation tool, Google translation. With the method of translating directly from English to Vietnamese, we found that the descriptions are sometimes confusing and unnatural to native people. Moreover, image understandings are cultural dependent, as in Western, people usually have different ways to grasp images and different vocabulary choices for describing contexts. For instance, in Fig. FIGREF2, one MS-COCO English caption introduce about \"a baseball player in motion of pitching\", which makes sense and capture accurately the main activity in the image. Though it sounds sensible in English, the sentence becomes less meaningful when we try to translate it into Vietnamese. One attempt of translating the sentence is performed by Google Translation, and the result is not as expected.\n\n\nTherefore, we come up with the approach of constructing a Vietnamese Image Captioning dataset with descriptions written manually by human. Composed by Vietnamese people, the sentences would be more natural and friendlier to Vietnamese users. The main resources we used from MS-COCO for our dataset are images. Besides, we consider having our dataset focus on sportball category due to several reasons:\nBy concentrating on a specific domain we are more likely to improve performance of the Image Captioning models. We expect our dataset can be used to confirm or reject this hypothesis.\nSportball Image Captioning can be used in certain sport applications, such as supportting journalists describing great amount of images for their articles.\nOur primary contributions of this paper are as follows:\nFirstly, we introduce UIT-ViIC, the first Vietnamese dataset extending MS-COCO with manually written captions for Image Captioning. UIT-ViIC is published for research purposes.\nSecondly, we introduce our annotation tool for dataset construction, which is also published to help annotators conveniently create captions.\nFinally, we conduct experiments to evaluate state-of-the-art models (evaluated on English dataset) on UIT-ViIC dataset, then we analyze the performance results to have insights into our corpus.\nThe structure of the paper is organized as follows. Related documents and studies are presented in Section SECREF2. UIT-ViIC dataset creation is described in Section SECREF3. Section SECREF4 describes the methods we implement. The experimental results and analysis are presented in Section SECREF5. Conclusion and future work are deduced in Section SECREF6.\nWith the method of translating directly from English to Vietnamese, we found that the descriptions are sometimes confusing and unnatural to native people.",

        "evidence": "NLG is the process of automatically generating coherent NL text from non-linguistic data BIBREF0. Recently, the field has seen an increased interest in the development of NLG systems focusing on verbalizing resources from SW data BIBREF1. The SW aims to make information available on the Web easier to process for machines and humans. However, the languages underlying this vision, i.e., RDF, SPARQL and OWL, are rather difficult to understand for non-expert users. For example, while the meaning of the OWL class expression Class: Professor SubClassOf: worksAt SOME University is obvious to every SW expert, this expression (“Every professor works at a university”) is rather difficult to fathom for lay persons.\nPrevious works such as SPARQL2NL BIBREF2 and SPARTIQULATION BIBREF3 have already shown the usefulness of the verbalization of SPARQL and RDF in areas such as question answering BIBREF4 and the explanation of the output of systems based onSW technologies BIBREF5. However, other SW languages are rarely investigated, such as OWL.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL. Our framework is based on a bottom-up paradigm for verbalizing SW data. Additionally, LD2NL builds upon SPARQL2NL as it is open-source and the paradigm it follows can be reused and ported to RDF and OWL. Thus, LD2NL is capable of generating either a single sentence or a summary of a given resource, rule, or query. To validate our framework, we evaluated LD2NL using experts 66 in NLP and SW as well as 20 non-experts who were lay users or non-users of SW. The results suggest that LD2NL generates texts which can be easily understood by humans. The version of LD2NL used in this paper, all experimental results will be publicly available.\nIn this paper, we present an open-source holistic NLG framework for the SW, named LD2NL, which facilitates the verbalization of the three key languages of the SW, i.e., RDF, OWL, and SPARQL into NL.",

        "evidence": "Neural network based models have been widely exploited with the prosperities of Deep Learning BIBREF0 and achieved inspiring performances on many NLP tasks, such as text classification BIBREF1 , BIBREF2 , semantic matching BIBREF3 , BIBREF4 and machine translation BIBREF5 . These models are robust at feature engineering and can represent words, sentences and documents as fix-length vectors, which contain rich semantic information and are ideal for subsequent NLP tasks.\nOne formidable constraint of deep neural networks (DNN) is their strong reliance on large amounts of annotated corpus due to substantial parameters to train. A DNN trained on limited data is prone to overfitting and incapable to generalize well. However, constructions of large-scale high-quality labeled datasets are extremely labor-intensive. To solve the problem, these models usually employ a pre-trained lookup table, also known as Word Embedding BIBREF6 , to map words into vectors with semantic implications. However, this method just introduces extra knowledge and does not directly optimize the targeted task. The problem of insufficient annotated resources is not solved either.\nMulti-task learning leverages potential correlations among related tasks to extract common features, increase corpus size implicitly and yield classification improvements. Inspired by BIBREF7 , there are a large literature dedicated for multi-task learning with neural network based models BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 . These models basically share some lower layers to capture common features and further feed them to subsequent task-specific layers, which can be classified into three types:\nIn this paper, we propose a generalized multi-task learning architecture with four types of recurrent neural layers for text classification. The architecture focuses on Type-III, which involves more complicated interactions but has not been researched yet. All the related tasks are jointly integrated into a single system and samples from different tasks are trained in parallel. In our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer. We also design a global memory storage to share common features and collect interactions among all tasks.\nWe conduct extensive experiments on five benchmark datasets for text classification. Compared to learning separately, jointly learning multiple relative tasks in our model demonstrate significant performance gains for each task.\nOur contributions are three-folds:\nIn our model, every two tasks can directly interact with each other and selectively absorb useful information, or communicate indirectly via a shared intermediate layer.",

Glyn was commenting on a report underscoring the dilemma of rocketing house prices outstripping what locals could pay, with the report warning that \"...traditional Welsh communities could die out...\" as a consequence.\n\nIn 2001 nearly a third of all purchases of properties in Gwynedd were by buyers from out of the county, with some communities reporting as many as a third of local homes used as holiday homes. Holiday home owners typically spend less than six months of the year in the local community.\n\nThe issue of locals being priced out of the local housing market is common to many rural communities throughout Britain, but in Wales the added dimension of language further complicates the issue, as many new residents do not learn the Welsh language.\n\nConcerned for the Welsh language under these pressures, Glyn said \"Once you have more than 50% of anybody living in a community that speaks a foreign language, then you lose your indigenous tongue almost immediately\". His comments attracted strong criticism of Plaid Cymru from other national parties.\n\nBy spring 2002 both the Snowdonia National Park (Welsh: Parc Cenedlaethol Eryri) and Pembrokeshire Coast National Park (Welsh: Parc Cenedlaethol Arfordir Penfro) authorities began limiting second home ownership within the parks, following the example set by Exmoor.

In this paper, we investigate how appropriate such data is for modeling natural dialog, and introduce Interview, a new high-quality large-scale open-domain conversational dataset grounded in interview settings with annotations for specific speaker roles.\nWe compare the performance of state-of-the-art language models fine-tuned on Interview and other popular conversational datasets, demonstrating that Interview contains more complex dialog and better models the characteristics of natural spoken conversations. Our dataset is an order of magnitude larger than existing high-quality natural dialog datasets and contains speaker role annotations for each turn, facilitating the development of conversational agents and assistive systems for settings involving specific speaker roles, such as doctor-patient interviews or hosted talk shows.\nIn particular, we explore the tasks of role modeling in media dialog and role change detection on Interview and find that leveraging role information can enable more nuanced, on-topic and natural dialog generation, as well as improve role change classification performance.\nIn summary, we present Interview, the first large-scale open-domain media dialog dataset.

        "answer": "The paper shows that training models on this new dataset leads to state-of-the-art performance on a variety of popular natural language understanding (NLU) benchmarks, categorizes the data by inference type to examine weaknesses, and demonstrates good performance on NLI stress tests.",
        "evidence": "Progress in AI has been driven by, among other things, the development of challenging large-scale benchmarks like ImageNet BIBREF0 in computer vision, and SNLI BIBREF1, SQuAD BIBREF2, and others in natural language processing (NLP). Recently, for natural language understanding (NLU) in particular, the focus has shifted to combined benchmarks like SentEval BIBREF3 and GLUE BIBREF4, which track model performance on multiple tasks and provide a unified platform for analysis.\nWith the rapid pace of advancement in AI, however, NLU benchmarks struggle to keep up with model improvement. Whereas it took around 15 years to achieve “near-human performance” on MNIST BIBREF5, BIBREF6, BIBREF7 and approximately 7 years to surpass humans on ImageNet BIBREF8, BIBREF0, BIBREF9, the GLUE benchmark did not last as long as we would have hoped after the advent of BERT BIBREF10, and rapidly had to be extended into SuperGLUE BIBREF11. This raises an important question: Can we collect a large benchmark dataset that can last longer?\nThe speed with which benchmarks become obsolete raises another important question: are current NLU models genuinely as good as their high performance on benchmarks suggests? A growing body of evidence shows that state-of-the-art models learn to exploit spurious statistical patterns in datasets BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17, instead of learning meaning in the flexible and generalizable way that humans do. Given this, human annotators—be they seasoned NLP researchers or non-experts—might easily be able to construct examples that expose model brittleness.\nWe propose an iterative, adversarial human-and-model-in-the-loop solution for NLU dataset collection that addresses both benchmark longevity and robustness issues. In the first stage, human annotators devise examples that our current best models cannot determine the correct label for. These resulting hard examples—which should expose additional model weaknesses—can be added to the training set and used to train a stronger model. We then subject the strengthened model to human interference and collect more weaknesses over several rounds. After each round, we both train a new model, and set aside a new test set. The process can be iteratively repeated in a never-ending learning BIBREF18 setting, with the model getting stronger and the test set getting harder in each new round.This process yields a “moving post” dynamic target for NLU systems, rather than a static benchmark that will eventually saturate.\nOur approach draws inspiration from recent efforts that gamify collaborative training of machine learning agents over multiple rounds BIBREF19 and pit “builders” against “breakers” to learn better models BIBREF20. Recently, Dinan2019build showed that a similar approach can be used to make dialogue safety classifiers more robust. Here, we focus on natural language inference (NLI), arguably the most canonical task in NLU. We collected three rounds of data, and call our new dataset Adversarial NLI (ANLI).\nOur contributions are as follows: 1) We introduce a novel human-and-model-in-the-loop dataset, currently consisting of three rounds that progressively increase in difficulty and complexity, that includes annotator-provided explanations. 2) We show that training models on this new dataset leads to state-of-the-art performance on a variety of popular NLI benchmarks. 3) We provide a detailed analysis of the collected data that sheds light on the shortcomings of current models, categorizes the data by inference type to examine weaknesses, and demonstrates good performance on NLI stress tests.

We note the BLEU score improves in all cases, even when given the wrong gender of either the speaker or the audience. We hypothesise this improvement stems from the addition of the word “said” which hints the model to generate a more “spoken” language which matches the tested scenario. Providing correct information for both speaker and audience usually helps more than providing correct information to either one of them individually. The one outlier is providing “She” for the speaker and “her” for the audience.

        "question": "What is genome analysis?",
        "evidence": "",
        "answer": "The genome sequence of an organism includes the collective DNA sequences of each chromosome in the organism. For a bacterium containing a single chromosome, a genome project will aim to map the sequence of that chromosome. For the human species, whose genome includes 22 pairs of autosomes and 2 sex chromosomes, a complete genome sequence will involve 46 separate chromosome sequences.\n\nThe Human Genome Project is a well known example of a genome project.\n\nGenome assembly refers to the process of taking a large number of short DNA sequences and reassembling them to create a representation of the original chromosomes from which the DNA originated. In a shotgun sequencing project, all the DNA from a source (usually a single organism, anything from a bacterium to a mammal) is first fractured into millions of small pieces. These pieces are then \"read\" by automated sequencing machines. A genome assembly algorithm works by taking all the pieces and aligning them to one another, and detecting all places where two of the short sequences, or reads, overlap. These overlapping reads can be merged, and the process continues.\n\nGenome assembly is a very difficult computational problem, made more difficult because many genomes contain large numbers of identical sequences, known as repeats. These repeats can be thousands of nucleotides long, and occur different locations, especially in the large genomes of plants and animals.\n\nThe resulting (draft) genome sequence is produced by combining the information sequenced contigs and then employing linking information to create scaffolds. Scaffolds are positioned along the physical map of the chromosomes creating a \"golden path\".\n\nOriginally, most large-scale DNA sequencing centers developed their own software for assembling the sequences that they produced. However, this has changed as the software has grown more complex and as the number of sequencing centers has increased. An example of such assembler Short Oligonucleotide Analysis Package developed by BGI for de novo assembly of human-sized genomes, alignment, SNP detection, resequencing, indel finding, and structural variation analysis.\n\nSince the 1980s, molecular biology and bioinformatics have created the need for DNA annotation. DNA annotation or genome annotation is the process of identifying attaching biological information to sequences , and particularly in identifying the locations of genes and determining what those genes do.\n\nWhen sequencing a genome, there are usually regions that are difficult to sequence (often regions with highly repetitive DNA). Thus, 'completed' genome sequences are rarely ever complete, and terms such as 'working draft' or 'essentially complete' have been used to more accurately describe the status of such genome projects. Even when every base pair of a genome sequence has been determined, there are still likely to be errors present because DNA sequencing is not a completely accurate process. It could also be argued that a complete genome project should include the sequences of mitochondria and (for plants) chloroplasts as these organelles have their own genomes.\n\nIt is often reported that the goal of sequencing a genome is to obtain information about the complete set of genes in that particular genome sequence. The proportion of a genome that encodes for genes may be very small (particularly in eukaryotes such as humans, where coding DNA may only account for a few percent of the entire sequence). However, it is not always possible (or desirable) to only sequence the coding regions separately. Also, as scientists understand more about the role of this noncoding DNA (often referred to as junk DNA), it will become more important to have a complete genome sequence as a background to understanding the genetics and biology of any given organism.\n\nIn many ways genome projects do not confine themselves to only determining a DNA sequence of an organism. Such projects may also include gene prediction to find out where the genes are in a genome, and what those genes do. There may also be related projects to sequence ESTs or mRNAs to help find out where the genes actually are.",

        "question": "How does the lattice rescoring procedure work?",
        "answer": "The authors also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model.",
        "evidence": "As language processing tools become more prevalent concern has grown over their susceptibility to social biases and their potential to propagate bias BIBREF1, BIBREF2. Natural language training data inevitably reflects biases present in our society. For example, gender bias manifests itself in training data which features more examples of men than of women. Tools trained on such data will then exhibit or even amplify the biases BIBREF3.\nGender bias is a particularly important problem for Neural Machine Translation (NMT) into gender-inflected languages. An over-prevalence of some gendered forms in the training data leads to translations with identifiable errors BIBREF0. Translations are better for sentences involving men and for sentences containing stereotypical gender roles. For example, mentions of male doctors are more reliably translated than those of male nurses BIBREF2, BIBREF4.\nRecent approaches to the bias problem in NLP have involved training from scratch on artificially gender-balanced versions of the original dataset BIBREF5, BIBREF6 or with de-biased embeddings BIBREF7, BIBREF8. While these approaches may be effective, training from scratch is inefficient and gender-balancing embeddings or large parallel datasets are challenging problems BIBREF9.\nInstead we propose treating gender debiasing as a domain adaptation problem, since NMT models can very quickly adapt to a new domain BIBREF10. To the best of our knowledge this work is the first to attempt NMT bias reduction by fine-tuning, rather than retraining. We consider three aspects of this adaptation problem: creating less biased adaptation data, parameter adaptation using this data, and inference with the debiased models produced by adaptation.\nRegarding data, we suggest that a small, trusted gender-balanced set could allow more efficient and effective gender debiasing than a larger, noisier set. To explore this we create a tiny, handcrafted profession-based dataset for transfer learning. For contrast, we also consider fine-tuning on a counterfactual subset of the full dataset and propose a straightforward scheme for artificially gender-balancing parallel text for NMT.\nWe find that during domain adaptation improvement on the gender-debiased domain comes at the expense of translation quality due to catastrophic forgetting BIBREF11. We can balance improvement and forgetting with a regularised training procedure, Elastic Weight Consolidation (EWC), or in inference by a two-step lattice rescoring procedure.\nWe experiment with three language pairs, assessing the impact of debiasing on general domain BLEU and on the WinoMT challenge set BIBREF0. We find that continued training on the handcrafted set gives far stronger and more consistent improvements in gender-debiasing with orders of magnitude less training time, although as expected general translation performance as measured by BLEU decreases.\nWe further show that regularised adaptation with EWC can reduce bias while limiting degradation in general translation quality. We also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model. We believe this approach, rescoring with models targeted to remove bias, is novel in NMT. The rescoring procedure improves WinoMT accuracy by up to 30% with no decrease in BLEU on the general test set.\nRecent recommendations for ethics in Artificial Intelligence have suggested that social biases or imbalances in a dataset be addressed prior to model training BIBREF12. This recommendation presupposes that the source of bias in a dataset is both obvious and easily adjusted. We show that debiasing a full NMT dataset is difficult, and suggest alternative efficient and effective approaches for debiasing a model after it is trained. This avoids the need to identify and remove all possible biases prior to training, and has the added benefit of preserving privacy, since no access to the original data or knowledge of its contents is required. As evidence, in section SECREF43, we show this scheme can be applied to remove gender bias in the output of ‘black box‘ online commercial MT systems.\nWe also present a lattice rescoring procedure in which initial hypotheses produced by the biased baseline system are transduced to create gender-inflected search spaces which can be rescored by the adapted model.",

He inspired movements for civil rights and freedom across the world. The honorific Mahātmā (Sanskrit: \"great-souled\", \"venerable\"), first applied to him in 1914 in South Africa, is now used throughout the world.\n\nBorn and raised in a Hindu family in coastal Gujarat, Gandhi trained in the law at the Inner Temple, London, and was called to the bar at age 22 in June 1891.

He began to live in a self-sufficient residential community, to eat simple food, and undertake long fasts as a means of both introspection and political protest.

        "answer": "The performance of state-of-the-art keyphrase generation models.",
        "evidence": "Keyphrases are single or multi-word lexical units that best summarise a document BIBREF0. As such, they are of great importance for indexing, categorising and browsing digital libraries BIBREF1. Yet, very few documents have keyphrases assigned, thus raising the need for automatic keyphrase generation systems. This task falls under the task of automatic keyphrase extraction which can also be the subtask of finding keyphrases that only appear in the input document. Generating keyphrases can be seen as a particular instantiation of text summarization, where the goal is not to produce a well-formed piece of text, but a coherent set of phrases that convey the most salient information. Those phrases may or may not appear in the document, the latter requiring some form of abstraction to be generated. State-of-the-art systems for this task rely on recurrent neural networks BIBREF2, BIBREF3, BIBREF4, and hence require large amounts of annotated training data to achieve good performance. As gold annotated data is expensive and difficult to obtain BIBREF5, previous works focused on readily available scientific abstracts and used author-assigned keyphrases as a proxy for expert annotations. However, this poses two major issues: 1) neural models for keyphrase generation do not generalize well across domains, thus limiting their use in practice; 2) author-assigned keyphrases exhibit strong consistency issues that negatively impacts the model's performance. There is therefore a great need for annotated data from different sources, that is both sufficiently large to support the training of neural-based models and that comprises gold-standard labels provided by experts. In this study, we address this need by providing KPTimes, a dataset made of 279 923 news articles that comes with editor-assigned keyphrases.\nOnline news are particularly relevant to keyphrase generation since they are a natural fit for faceted navigation BIBREF6 or topic detection and tracking BIBREF7. Also, and not less importantly, they are available in large quantities and are sometimes accompanied by metadata containing human-assigned keyphrases initially intended for search engines. Here, we divert these annotations from their primary purpose, and use them as gold-standard labels to automatically build our dataset. More precisely, we collect data by crawling selected news websites and use heuristics to draw texts paired with gold keyphrases. We then explore the resulting dataset to better understand how editors tag documents, and how these expert annotations differ from author-assigned keyphrases found in scholarly documents. Finally, we analyse the performance of state-of-the-art keyphrase generation models and investigate their transferability to the news domain and the impact of domain shift.\nFinally, we analyse the performance of state-of-the-art keyphrase generation models and investigate their transferability to the news domain and the impact of domain shift.",

        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nA recurrent structure is implemented to mine the deep relation between a query and a text.",

        "evidence": "Deep learning systems have shown a lot of promise for extractive Question Answering (QA), with performance comparable to humans when large scale data is available. However, practitioners looking to build QA systems for specific applications may not have the resources to collect tens of thousands of questions on corpora of their choice. At the same time, state-of-the-art machine reading systems do not lend well to low-resource QA settings where the number of labeled question-answer pairs are limited (c.f. Table 2 ). Semi-supervised QA methods like BIBREF0 aim to improve this performance by leveraging unlabeled data which is easier to collect.\nIn this work, we present a semi-supervised QA system which requires the end user to specify a set of base documents and only a small set of question-answer pairs over a subset of these documents. Our proposed system consists of three stages. First, we construct cloze-style questions (predicting missing spans of text) from the unlabeled corpus; next, we use the generated clozes to pre-train a powerful neural network model for extractive QA BIBREF1 , BIBREF2 ; and finally, we fine-tune the model on the small set of provided QA pairs.\nOur cloze construction process builds on a typical writing phenomenon and document structure: an introduction precedes and summarizes the main body of the article. Many large corpora follow such a structure, including Wikipedia, academic papers, and news articles. We hypothesize that we can benefit from the un-annotated corpora to better answer various questions – at least ones that are lexically similar to the content in base documents and directly require factual information.\nWe apply the proposed system on three datasets from different domains – SQuAD BIBREF3 , TriviaQA-Web BIBREF4 and the BioASQ challenge BIBREF5 . We observe significant improvements in a low-resource setting across all three datasets. For SQuAD and TriviaQA, we attain an F1 score of more than 50% by merely using 1% of the training data. Our system outperforms the approaches for semi-supervised QA presented in BIBREF0 , and a baseline which uses the same unlabeled data but with a language modeling objective for pretraining. In the BioASQ challenge, we outperform the best performing system from previous year's challenge, improving over a baseline which does transfer learning from the SQuAD dataset. Our analysis reveals that questions which ask for factual information and match to specific parts of the context documents benefit the most from pretraining on automatically constructed clozes.\nWe apply the proposed system on three datasets from different domains — SQuAD (Rajpurkar et al., 2016), TriviaQA-Web (Joshi et al., 2017) and the BioASQ challenge (Tsatsaronis et al., 2015).",

        "answer": "For the classification of life events based on individual tweets.",
        "evidence": "Micro-blogging social media platforms have become very popular in recent years. One of the most popular platforms is Twitter, which allows users to broadcast short texts (i.e., 140 characters initially, and 280 characters in a recent platform update) in real time with almost no restrictions on content. Twitter is a source of people’s attitudes, opinions, and thoughts toward the things that happen in their daily life. Twitter data are publicly accessible through Twitter application programming interface (API); and there are several tools to download and process these data. Twitter is being increasingly used as a valuable instrument for surveillance research and predictive analytics in many fields including epidemiology, psychology, and social sciences. For example, Bian et al. explored the relation between promotional information and laypeople’s discussion on Twitter by using topic modeling and sentiment analysis BIBREF0. Zhao et al. assessed the mental health signals among sexual and gender minorities using Twitter data BIBREF1. Twitter data can be used to study and predict population-level targets, such as disease incidence BIBREF2, political trends BIBREF3, earthquake detection BIBREF4, and crime perdition BIBREF5, and individual-level outcomes or life events, such as job loss BIBREF6, depression BIBREF7, and adverse events BIBREF8. Since tweets are unstructured textual data, natural language processing (NLP) and machine learning, especially deep learning nowadays, are often used for preprocessing and analytics. However, for many studiesBIBREF9, BIBREF10, BIBREF11, especially those that analyze individual-level targets, manual annotations of several thousands of tweets, often by experts, is needed to create gold-standard training datasets, to be fed to the NLP and machine learning tools for subsequent, reliable automated processing of millions of tweets. Manual annotation is obviously labor intense and time consuming.\nCrowdsourcing can scale up manual labor by distributing tasks to a large set of workers working in parallel instead of a single people working serially BIBREF12. Commercial platforms such as Amazon’s Mechanical Turk (MTurk, https://www.\nmturk.com/), make it easy to recruit a large crowd of people working remotely to perform time consuming manual tasks such as entity resolution BIBREF13, BIBREF14, image or sentiment annotation BIBREF15, BIBREF16. The annotation tasks published on MTurk can be done on a piecework basis and, given the very large pool of workers usually available (even by selecting a subset of those who have, say, a college degree), the tasks can be done almost immediately. However, any crowdsourcing service that solely relies on human workers will eventually be expensive when large datasets are needed, that is often the case when creating training datasets for NLP and deep learning tasks. Therefore, reducing the training dataset size (without losing performance and quality) would also improve efficiency while contain costs.\nQuery optimization techniques (e.g., active learning) can reduce the number of tweets that need to be labeled, while yielding comparable performance for the downstream machine learning tasks BIBREF17, BIBREF18, BIBREF19. Active learning algorithms have been widely applied in various areas including NLP BIBREF20 and image processing BIBREF21. In a pool-based active learning scenario, data samples for training a machine learning algorithm (e.g., a classifier for identifying job loss events) are drawn from a pool of unlabeled data according to some forms of informativeness measure (a.k.a. active learning strategies BIBREF22), and then the most informative instances are selected to be annotated. For a classification task, in essence, an active learning strategy should be able to pick the “best” samples to be labelled that will improve the classification performance the most.\nIn this study, we integrated active learning into a crowdsourcing pipeline for the classification of life events based on individual tweets. We analyzed the quality of crowdsourcing annotations and then experimented with different machine/deep learning classifiers combined with different active learning strategies to answer the following two research questions (RQs):\nRQ1. How does (1) the amount of time that a human worker spends on and (2) the number of workers assigned to each annotation task impact the quality of an-notation results?\nRQ2. Which active learning strategy is most efficient and cost-effective to build event classification models using Twitter data?\n-5pt\nIn this study, we integrated active learning into a crowdsourcing pipeline for the classification of life events based on individual tweets.",

For example, items that a typical household consumes are captured in the Consumer Price Index, whereas items that domestic producers buy are included in the Producer Price Index. The drivers behind changes in the general price levels can be attributed to two main reasons. First, changes in the real demand and supply of goods and services will drive prices up or down. Higher prices will encourage suppliers to increase supply and discourage consumer demand reestablishing market equilibrium. Second, changes in the money supply –i.e. the amount of currency in circulation, bank deposits, and other liquid monetary aggregates– can lead to inflation. When a country's central bank decides to increase the money supply through quantitative easing monetary policies, the amount of currency available to buy and sell the same amount of goods and services increases. If the rate at which money is exchanged in an economy remains unchanged (i.e. velocity of money is constant) then a higher money supply will lead to higher prices because there is more money to transact the same amount of goods and services in the economy.",

The city's chief harbor, Elliott Bay, is part of Puget Sound, which makes the city an oceanic port. To the west, beyond Puget Sound, are the Kitsap Peninsula and Olympic Mountains on the Olympic Peninsula; to the east, beyond Lake Washington and the Eastside suburbs, are Lake Sammamish and the Cascade Range. Lake Washington's waters flow to Puget Sound through the Lake Washington Ship Canal (consisting of two man-made canals, Lake Union, and the Hiram M. Chittenden Locks at Salmon Bay, ending in Shilshole Bay on Puget Sound).[citation needed]\n\nThe sea, rivers, forests, lakes, and fields surrounding Seattle were once rich enough to support one of the world's few sedentary hunter-gatherer societies. The surrounding area lends itself well to sailing, skiing, bicycling, camping, and hiking year-round.\n\nThe city itself is hilly, though not uniformly so. Like Rome, the city is said to lie on seven hills; the lists vary but typically include Capitol Hill, First Hill, West Seattle, Beacon Hill, Queen Anne, Magnolia, and the former Denny Hill. The Wallingford, Delridge, Mount Baker, Seward Park, Washington Park, Broadmoor, Madrona, Phinney Ridge, Sunset Hill, Blue Ridge, Broadview, Laurelhurst, Hawthorne Hills, Maple Leaf, and Crown Hill neighborhoods are all located on hills as well. Many of the hilliest areas are near the city center, with Capitol Hill, First Hill, and Beacon Hill collectively constituting something of a ridge along an isthmus between Elliott Bay and Lake Washington. The break in the ridge between First Hill and Beacon Hill is man-made, the result of two of the many regrading projects that reshaped the topography of the city center. The topography of the city center was also changed by the construction of a seawall and the artificial Harbor Island (completed 1909) at the mouth of the city's industrial Duwamish Waterway, the terminus of the Green River. The highest point within city limits is at High Point in West Seattle, which is roughly located near 35th Ave SW and SW Myrtle St. Other notable hills include Crown Hill, View Ridge/Wedgwood/Bryant, Maple Leaf, Phinney Ridge, Mt. Baker Ridge, and Highlands/Carkeek/Bitterlake.[citation needed]\n\nNorth of the city center, Lake Washington Ship Canal connects Puget Sound to Lake Washington. It incorporates four natural bodies of water: Lake Union, Salmon Bay, Portage Bay, and Union Bay.[citation needed]\n\nDue to its location in the Pacific Ring of Fire, Seattle is in a major earthquake zone. On February 28, 2001, the magnitude 6.8 Nisqually earthquake did significant architectural damage, especially in the Pioneer Square area (built on reclaimed land, as are the Industrial District and part of the city center), and caused one fatality. Other strong quakes occurred on January 26, 1700 (estimated at 9 magnitude), December 14, 1872 (7.3 or 7.4), April 13, 1949 (7.1), and April 29, 1965 (6.5). The 1965 quake caused three deaths in Seattle directly and one more by heart failure. Although the Seattle Fault passes just south of the city center, neither it nor the Cascadia subduction zone has caused an earthquake since the city's founding. The Cascadia subduction zone poses the threat of an earthquake of magnitude 9.0 or greater, capable of seriously damaging the city and collapsing many buildings, especially in zones built on fill.\n\nAccording to the United States Census Bureau, the city has a total area of 142.5 square miles (369 km2), 83.9 square miles (217 km2) of which is land and 58.7 square miles (152 km2), water (41.16% of the total area).[citation needed]",

        "question": "Does the model verify the theory about the aligned unmatched parts and illustrate the effectiveness of the methodology?",
        "answer": "Yes, it does.",
        "evidence": "Paraphrase identification is an important topic in artificial intelligence and this task justifies whether two sentences expressed in various forms are semantically similar, BIBREF0 . For example, “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend” are identified as paraphrase. This task directly benefits many industrial applications, such as plagiarism identification BIBREF0 , machine translation BIBREF1 and removing redundancy questions in Quora website BIBREF2 . Recently, there emerge many methods, such as ABCNN BIBREF3 , Siamese LSTM BIBREF2 and L.D.C BIBREF4 .\nConventionally, neural methodology aligns the sentence pair and then generates a matching score for paraphrase identification, BIBREF4 , BIBREF2 . Regarding the alignment, we conjecture that the aligned unmatched parts are semantically critical, where we define the corresponded word pairs with low similarity as aligned unmatched parts. For an example: “On Sunday, the boy runs in the yard” and “The child runs inside at the weekend”, the matched parts (i.e. (Sunday, weekend), (boy, child), run) barely make contribution to the semantic sentence similarity, but the unmatched parts (i.e. “yard” and “inside”) determine these two sentences are semantically dissimilar. For another example: “On Sunday, the boy runs in the yard” and “The child runs outside at the weekend”, the aligned unmatched parts (i.e. “yard” and “outside”) are semantically similar, which makes the two sentences paraphrase. In conclusion, if the aligned unmatched parts are semantically consistent, the two sentences are paraphrase, otherwise they are non-paraphrase.\nTraditional alignment methods take advantage of attention mechanism BIBREF2 , which is a soft-max weighting technique. Weighting technique could pick out the most similar/dissimilar parts, but is weak in modeling the aligned unmatched parts, which are the crucial evidence to identify paraphrase. For the input sentences in Figure FIGREF1 , the weight between “Sunday” and “run” is lower than the weight between “yard” and “inside”, but the former weight is not the evidence of paraphrase/non-paraphrase, because the former two words that are most dissimilar should not be aligned for an inappropriate comparison.\nTo extract the aligned unmatched parts, in this paper, we embed Hungarian algorithm BIBREF5 into neural architecture as Hungarian layer (Algorithm SECREF7 ). Illustrated in Figure FIGREF1 , the alignment in sentence matching could be formulated as the task-assignment problem, which is tackled by Hungarian algorithm. Simply, Hungarian algorithm works out the theoretically optimal alignment relationship in an exclusive manner and the exclusiveness characterizes the aligned unmatched parts. For the example in Figure FIGREF1 , because Hungarian layer allocates the aligned pairs with exclusiveness, the matched parts (i.e (Sunday, weekend), (boy, child), run) are aligned firstly, then the word “yard” would be assigned to the word “inside” with a negative similarity, making a strong evidence for discrimination.\nSpecifically, our model performs this task in three steps. First, our model applies BiLSTM to parse the input sentences into hidden representations. Then, Hungarian layer leverages the hidden representations to extract the aligned unmatched parts. Last, we apply cosine similarity to metric the aligned unmatched parts for a final discrimination. Regarding the training process of Hungarian layer, we modify the back-propagation algorithm in both directions. In the forward pass, Hungarian layer works out the alignment relationship, according to which, the computational graph is dynamically constructed, as demonstrated in Figure FIGREF13 . Once the computational graph has been dynamically constructed, the backward propagation could be performed as usual in a conventional graph.\nWe conduct our experiments on the public benchmark dataset of “Quora Question Pairs” for the task of paraphrase identification. Experimental results demonstrate that our model outperforms other baselines extensively and significantly, which verifies our theory about the aligned unmatched parts and illustrates the effectiveness of our methodology.\nContributions. (1.) We offer a new perspective for paraphrase identification, which focuses on the aligned unmatched parts of two sentences. Accordingly, we propose the Hungarian layer to extract the aligned unmatched parts. The proposed method can achieve hard and exclusive alignments between two sequences, while we can learn parameters by end-to-end back-propagation. (2.) Our model outperforms other baselines extensively, verifying the effectiveness of our theory and method.\nOrganization. In Section 2, we survey the related work of paraphrase identification and dynamic differentiable computational graphs. In Section 3, we introduce our neural architecture. In Section 4, we conduct the experiments. In Section 5, we conclude our paper and publish our codes.\nExperimental results demonstrate that our model outperforms other baselines extensively and significantly, which verifies our theory about the aligned unmatched parts and illustrates the effectiveness of our methodology.",

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nWe find that the neural networks largely outperform the classical methods.",

        "evidence": "The study of gender and language has a rich history in social science. Its roots are often attributed to Robin Lakoff, who argued that language is fundamental to gender inequality, “reflected in both the ways women are expected to speak, and the ways in which women are spoken of” BIBREF2. Prominent scholars following Lakoff have included Deborah Tannen BIBREF3, Mary Bucholtz and Kira Hall BIBREF4, Janet Holmes BIBREF5, Penelope Eckert BIBREF6, and Deborah Cameron BIBREF7, along with many others.\nIn recent decades, the study of gender and language has also attracted computational researchers. Echoing Lakoff's original claim, a popular strand of computational work focuses on differences in how women and men talk, analyzing key lexical traits BIBREF8, BIBREF9, BIBREF10 and predicting a person's gender from some text they have written BIBREF11, BIBREF12. There is also research studying how people talk to women and men BIBREF13, as well as how people talk about women and men, typically in specific domains such as sports journalism BIBREF14, fiction writing BIBREF15, movie scripts BIBREF16, and Wikipedia biographies BIBREF17, BIBREF18. Our work builds on this body by diving into two novel domains: celebrity news, which explores gender in pop culture, and student reviews of CS professors, which examines gender in academia and, particularly, the historically male-dominated field of CS. Furthermore, many of these works rely on manually constructed lexicons or topics to pinpoint gendered language, but our methods automatically infer gender-associated words and labeled clusters, thus reducing supervision and increasing the potential to discover subtleties in the data.\nModeling gender associations in language could also be instrumental to other NLP tasks. Abusive language is often founded in sexism BIBREF0, BIBREF1, so models of gender associations could help to improve detection in those cases. Gender bias also manifests in NLP pipelines: prior research has found that word embeddings preserve gender biases BIBREF19, BIBREF20, BIBREF21, and some have developed methods to reduce this bias BIBREF22, BIBREF23. Yet, the problem is far from solved; for example, BIBREF24 showed that it is still possible to recover gender bias from “de-biased” embeddings. These findings further motivate our research, since before we can fully reduce gender bias in embeddings, we need to develop a deeper understanding of how gender permeates through language in the first place.\nWe also build on methods to cluster words in word embedding space and automatically label clusters. Clustering word embeddings has proven useful for discovering salient patterns in text corpora BIBREF25, BIBREF26. Once clusters are derived, we would like them to be interpretable. Much research simply considers the top-n words from each cluster, but this method can be subjective and time-consuming to interpret. Thus, there are efforts to design methods of automatic cluster labeling BIBREF27. We take a similar approach to BIBREF28, who leverage word embeddings and WordNet during labeling, and we extend their method with additional techniques and evaluations.\nWe also build on methods to cluster words in word embedding space and automatically label clusters.",

Other authors have experimented with distributed representations, such as ahmed2011unified, who cluster news into storylines using Markov chain Monte Carlo methods, rehureklrec who used incremental Singular Value Decomposition (SVD) to find relevant topics from streaming data, and sato2017distributed who used the paragraph vector model BIBREF6 in an offline clustering setting.\nMore recently, crosslingual linking of clusters has been discussed by rupnik2016news in the context of linking existing clusters from the Event Registry BIBREF7 in a batch fashion, and by steinberger2016mediagist who also present a batch clustering linking system. However, these are not “truly” online crosslingual clustering systems since they only decide on the linking of already-built monolingual clusters.

        "question": "What should I look for when looking for a used car?",
        "evidence": "",
        "answer": "Items to look for when looking to purchase a used car:\n\n* First of all, ask about any major work done to the car like engine, suspension, body work. If it's been in any accidents that may have impacted it's chassis at all. Later on when we're examining the car we may find evidence of damage or repair work, and it's good to know if the seller is lying to cover up any issues before we start negotiating price with them. Pulling the carfax can also be a good way to check if the seller is lying since it often contains detailed information about repair that has been performed to the car. If you notice that the seller is lying either after pulling the carfax or after inspecting the body, it's best not to purchase the car.\n\n* Ask the owner if they have any maintenance records. If they do, that not only means that the car has received the proper care but it also illustrates that the buyer is the kind of person that is very organized and likes to keep their processions in good condition, which is super important. That's the kind of person you want to be buying a car from. Also note that if the owner has been taking the car to the dealership or to an independent shop it's very easy to obtain these service records using the VIN number either online or by calling the mechanic directly.\n\n* Cars having a timing belt needs to be replaced every 70,000-100,000 miles. You can easily check if the car you're planning on purchasing has a timing belt or timing chain. Typically timing chains do not need to be replaced for the life of the car, so finding a car with a timing chain means that you have to worry less about this aspect. Depending on the car replacing the timing belt can be from 1,000 to 6,000 dollars so it's a pretty significant expense that you should take into account.\n\n* Ask how frequently the owner has been changing the oil. In most cases changing it every 3,000 to 6,000 or every year (whichever comes first) is ideal. Many owner manuals mention that you can go over this mileage. In some cases manuals mention oil change intervals of 10,000 or 20,000 miles. Personally, I would not consider a car that has its oil replaced this infrequently. In many cases, these longer intervals are an attempt by the manufacturer's marketing department  to make the car more appealing to buyers if it requires less maintenance. Also ask if they've been using synthetic oil. Typically synthetic oil doesn't break down over time so longer intervals might be ok.\n\n* Ask when was the last time brake pads and rotors have been replaced. Typically brake pads need to be replaced every 50000-100000 miles. Brake rotors can be trickier because whether or not needs replacing depends on its thickness, however if during the test drive you notice vibration when braking, it's likely due to the brake rotors. If the owner hasn't replaced the brakes recently there might be a good opportunity for negotiating the price.\n\n* If the car is a manual ask if the clutch has been replaced. This is a wear item and the time to replace it depends on the usage (cars driven in cities with a lot of stop and go traffic will need a replacement more frequently than cars driving long distances on the freeway).\n\n* For automatics ask when was the last time the transmission fluid was changed. Typically this needs to be replaced every 50-60k miles. Again many service manuals mention that the transmission fluid does not need to be replaced at all, but that's arguably again due to marketing reasons.\n\n* Examine the tires and note how much tread is on the tires. If you were to imagine putting a penny into the tire's tread, a new tire would take up 1/3 - 1/2 of the penny. Also tires need to be replaced every 5 years. The tire sidewall has a 4 digit number which shows the week and year it was manufactured, so it's easy to check if it's due for a replacement. Lastly check if the tires (especially the front) are worn evenly. If the interior part is more worn compared to the exterior, they might indicate suspension or alignment issues. So these issues will need to be addressed and the tires will need to be replaced to fix that problem.\n\n* Ask for and look for any interior problems, bulbs, gauges, AC, power windows not working, stuff like that.\n\n* Check for rust in the wheel wells and rocker panels. Stand back from the car and look for any slight differences in color between it's exterior panels that may indicate they were replaced, also look for dents. The best and easiest indication that a car was repaired or in an accident is if the gaps between body panels is uneven. A good way to identify body panel issues is by running your finger across a body panel, if you feel that one part of the body is lower than the other or if that gap is not consistent, this might mean that the car has been in an accident.\n\n* Look for any signs of fluids, greasy stains on metal, anything that would indicate that it's leaked something. Oil leaks would look dark and greasy. Battery leaks look white and powdery. Coolant leaks look dark and smell sweet. Look at the bottom of the hood, if there are any leak stains there too. Also looks underneath the engine for any greasy spots, because fluids always drip down.\n\n* Do some parts on the car look newer/cleaner than others? A new radiator could mean that the car was recently in a frontal collision.\n\n* Listen to the engine. Does it sound like it's keeping a constant RPM? You may hear some ticking caused by piston slapping or poorly lubricated valves. These are signs that the engine is old, but isn't that big of a deal. Grinding noises are very bad and expensive to fix. Older engines can be pretty noisy until they warm up which is normal.\n\n* Ask the owner to rev the engine while you look at it. Does the engine hop violently when it's revved? This might mean that the engine mounts might need to be replaced.\n\n* Again, ask the owner to rev the engine, this time look at the exhaust. If any blue smoke comes out, or (if it's a warm day outside) any dense white smoke comes out it may indicate that the engine is burning oil, and unless you like adding oil to your engine as often as you fill up your gas tank, it'll be expensive to fix.\n\nTime to take it for a test drive!\n\n* Look at the gauge cluster, is the check engine light on? Keep an eye on the temperature gauge during your trip, does it fluctuate at all? A good car's temperature stays constant during it's trip.\n\n* Take some sharp turns at speed and listen to any thumping or squeeking noises that may come from the suspension or drive train.\n\n* Does the steering wheel shake at all? (when driving it could mean bad alignment or bad steering, when braking it could mean warped rotors)\n\n* Make sure you take the car in and out of all it's gears.\n\n* Listen for funny noises, rattles, squeeks, clanks, vibrations, etc. It's inevitable that older cars will have some interior panels rattle.\n\n* Accelerate hard and brake hard. If the car has ABS does it activate or do you feel that the wheels stop moving?\n\n* Go over some speed bumps, or go on a bumpy road. The car shouldn't be bouncy when recovering from a bump, and neither should it feel like riding over a bump in a shopping cart. It should absorb the bump in a firm but smooth manner.\n\n* After driving for a while, pull over to the side of the road and turn off the car. Pop the hood and look at the coolant resevoir (DON'T OPEN IT!!!) and check if the fluid inside is bubbling or boiling. If it is then the headgasket is blown.\n\n* Remember when we asked the owner when they changed their oil? New oil should look like honey, old oil should have the same color as dark coffee (dark coffee color is a good thing). If the oil is brown or any other funky colors or smells funny something might be wrong with the engine.\n\n* Once you let the car rest for a few minutes check the oil level by using the dipstick if it's not all the way to full, it might be burning or leaking oil.",

See media help.\nThe flat-six engine is most often associated with their 911 model, Porsche's flagship rear-engined sports car which has used flat-six engines exclusively since 1963. The engines were air-cooled until 1999, when Porsche started using water-cooled engines.\n\nIn April 2011, Porsche announced the third generation of the 997 GT3 RS with an enlarged 4.0-litre engine having a power output of 500 PS (368 kW; 493 hp). The naturally-aspirated 4.0-litre flat-six engine (the largest engine offered in a street-legal 911) was introduced with their 911 (997) GT3 RS 4.0, in 2011. The engine itself uses the crankshaft from the RSR with increased stroke dimensions (from 76.4 mm to 80.4 mm). This change increased the power output to 500 PS (368 kW; 493 hp) at 8,250 rpm and 460 N⋅m (339 lbf⋅ft) of torque at 5,750 rpm. giving it a power-to-weight ratio of 365 hp per ton. Only 600 cars were built. At 493 hp (368 kW), the engine is one of the most powerful six-cylinder naturally aspirated engines in any production car with a 123.25 hp (92 kW) per litre output.\n\nOther Porsche models that use flat-six engines are the 1970–1972 Porsche 914/6 (mid-engine), the 1986–1993 Porsche 959 (rear-engine), and the 1996–2021 Porsche Boxster/Cayman (mid-engine).\n\nThe Porsche 962 sports prototype also used a twin-turbocharged flat-six engine.\n\nThese engines have also been used by German tuning company RUF in various replica Porsche sports cars.",

        "evidence": "Pre-trained language models such as BERT BIBREF0 have significantly improved the accuracy of various language processing tasks. However, we cannot apply BERT to language generation tasks as is because its model structure is not suitable for language generation. Several pre-trained seq-to-seq models for language generation BIBREF1, BIBREF2 based on an encoder-decoder Transformer model, which is a standard model for language generation, have recently been proposed. These models have achieved blackstate-of-the-art results in various language generation tasks, including abstractive summarization.\nHowever, when generating a summary, it is essential to correctly predict which part of the source text should be included in the summary. Some previous studies without pre-training have examined combining extractive summarization with abstractive summarization BIBREF3, BIBREF4.

        "answer": "They are human factors, naive realism, algorithmic biases, the presence of deceptive agents on social platforms and the formation of echo chambers.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias (Nickerson 1998), naive realism (Reed, Turiel, and Brown 2013)), algorithmic biases (filter bubble effect (Allcott and Gentzkow 2017)), the presence of deceptive agents on social platforms (bots and trolls (Shao et al. 2018a)) and, lastly, the formation of echo chambers (Del Vicario et al. 2016) where people polarize their opinions as they are insulated from contrary perspectives",

The act of switching the context is not in itself very time consuming. The real performance hit comes from the fact that different processes have different virtual memory address spaces so all the caches in the system need to be invalidated and flushed. Since there is such a huge difference in how fast a cpu can run compared to how fast instructions and data can be retrieved from main memory, these things are cached close to the cpu in onboard caches. Even a pointer to a mapping of virtual addresses to physical addresses are cached so that memory access is faster. When a new process gets loaded by the cpu with a different address space and mapping of virtual to physical addresses, all of the data in the caches is invalid and needs to be flushed. This leaves the cpu with empty caches that have to be rebuilt from scratch for the new process, meaning there will be a big slowdown in retrieving instructions and data since these will now be coming from main memory, which is much slower than the cpu's cache.",

        "question": "How do they extract answers for a given question?",
        "answer": "Using a structured KB (here Freebase) by jointly performing entity linking and relation extraction.",
        "evidence": "Since the advent of large structured knowledge bases (KBs) like Freebase BIBREF0 , YAGO BIBREF1 and DBpedia BIBREF2 , answering natural language questions using those structured KBs, also known as KB-based question answering (or KB-QA), is attracting increasing research efforts from both natural language processing and information retrieval communities.\nThe state-of-the-art methods for this task can be roughly categorized into two streams. The first is based on semantic parsing BIBREF3 , BIBREF4 , which typically learns a grammar that can parse natural language to a sophisticated meaning representation language. But such sophistication requires a lot of annotated training examples that contains compositional structures, a practically impossible solution for large KBs such as Freebase. Furthermore, mismatches between grammar predicted structures and KB structure is also a common problem BIBREF4 , BIBREF5 , BIBREF6 .\nOn the other hand, instead of building a formal meaning representation, information extraction methods retrieve a set of candidate answers from KB using relation extraction BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 or distributed representations BIBREF11 , BIBREF12 . Designing large training datasets for these methods is relatively easy BIBREF7 , BIBREF13 , BIBREF14 . These methods are often good at producing an answer irrespective of their correctness. However, handling compositional questions that involve multiple entities and relations, still remains a challenge. Consider the question what mountain is the highest in north america. Relation extraction methods typically answer with all the mountains in North America because of the lack of sophisticated representation for the mathematical function highest. To select the correct answer, one has to retrieve all the heights of the mountains, and sort them in descending order, and then pick the first entry. We propose a method based on textual evidence which can answer such questions without solving the mathematic functions implicitly.\nKnowledge bases like Freebase capture real world facts, and Web resources like Wikipedia provide a large repository of sentences that validate or support these facts. For example, a sentence in Wikipedia says, Denali (also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. To answer our example question against a KB using a relation extractor, we can use this sentence as external evidence, filter out wrong answers and pick the correct one.\nUsing textual evidence not only mitigates representational issues in relation extraction, but also alleviates the data scarcity problem to some extent. Consider the question, who was queen isabella's mother. Answering this question involves predicting two constraints hidden in the word mother. One constraint is that the answer should be the parent of Isabella, and the other is that the answer's gender is female. Such words with multiple latent constraints have been a pain-in-the-neck for both semantic parsing and relation extraction, and requires larger training data (this phenomenon is coined as sub-lexical compositionality by wang2015). Most systems are good at triggering the parent constraint, but fail on the other, i.e., the answer entity should be female. Whereas the textual evidence from Wikipedia, ...her mother was Isabella of Barcelos ..., can act as a further constraint to answer the question correctly.\nWe present a novel method for question answering which infers on both structured and unstructured resources. Our method consists of two main steps as outlined in sec:overview. In the first step we extract answers for a given question using a structured KB (here Freebase) by jointly performing entity linking and relation extraction (sec:kb-qa). In the next step we validate these answers using an unstructured resource (here Wikipedia) to prune out the wrong answers and select the correct ones (sec:refine). Our evaluation results on a benchmark dataset WebQuestions show that our method outperforms existing state-of-the-art models. Details of our experimental setup and results are presented in sec:experiments. Our code, data and results can be downloaded from https://github.com/syxu828/QuestionAnsweringOverFB.\nIn the first step we extract answers for a given question using a structured KB (here Freebase) by jointly performing entity linking and relation extraction (sec:kb-qa).",

        "question": "What are some practical applications of Burnside's lemma in combinatorics based on this passage?",
        "evidence": "Burnside's lemma, sometimes also called Burnside's counting theorem, the Cauchy–Frobenius lemma, the orbit-counting theorem, or the lemma that is not Burnside's, is a result in group theory that is often useful in taking account of symmetry when counting mathematical objects. Its various eponyms are based on William Burnside, George Pólya, Augustin Louis Cauchy, and Ferdinand Georg Frobenius. The result is not due to Burnside himself, who merely quotes it in his book 'On the Theory of Groups of Finite Order', attributing it instead to Frobenius (1887). Burnside's Lemma counts \"orbits\", which is the same thing as counting distinct objects taking account of a symmetry. Other ways of saying it are counting distinct objects up to an equivalence relation R, or counting objects that are in canonical form.\n\nIn the following, let G be a finite group that acts on a set X. For each g in G, let Xg denote the set of elements in X that are fixed by g (also said to be left invariant by g), that is, Xg = { x ∈ X | g.x = x }. Burnside's lemma asserts the following formula for the number of orbits, denoted |X/G|:\n\n|\n�\n/\n�\n|\n=\n1\n|\n�\n|\n∑\n�\n∈\n�\n|\n�\n�\n|\n.\n{\\displaystyle |X/G|={\\frac {1}{|G|}}\\sum _{g\\in G}|X^{g}|.}\nThus the number of orbits (a natural number or +∞) is equal to the average number of points fixed by an element of G (which is also a natural number or infinity). If G is infinite, the division by |G| may not be well-defined; in this case the following statement in cardinal arithmetic holds:\n\n|\n�\n|\n|\n�\n/\n�\n|\n=\n∑\n�\n∈\n�\n|\n�\n�\n|\n.\n{\\displaystyle |G||X/G|=\\sum _{g\\in G}|X^{g}|.}\nExamples of applications to enumeration\nNecklaces\nThere are 8 possible bit vectors of length 3, but only four distinct 2-colored necklaces of length 3: 000, 001, 011, and 111, because 100 and 010 are equivalent to 001 by rotation; similarly 110 and 101 are equivalent to 011. The formula is based on the number of rotations, which in this case is 3 (including the null rotation), and the number of bit vectors left unchanged by each rotation. All 8 bit vectors are unchanged by the null rotation, and two (000 and 111) are unchanged by each of the other two rotations, giving: \n4\n=\n1\n3\n(\n8\n+\n2\n+\n2\n)\n{\\displaystyle 4={\\frac {1}{3}}(8+2+2)}.\n\nFor length 4, there are 16 possible bit vectors; 4 rotations; the null rotation leaves all 16 bit vectors unchanged; the 1-rotation and 3-rotation each leave two bit vectors unchanged (0000 and 1111); the 2-rotation leaves 4 bit vectors unchanged (0000, 0101, 1010, and 1111); giving: \n6\n=\n1\n4\n(\n16\n+\n2\n+\n4\n+\n2\n)\n{\\displaystyle 6={\\frac {1}{4}}(16+2+4+2)}. These are: 0000, 0001, 0011, 0101, 0111, and 1111.\n\nColorings of a cube\nThe number of rotationally distinct colourings of the faces of a cube using three colours can be determined from this formula as follows.\n\nLet X be the set of 36 possible face colour combinations that can be applied to a cube in one particular orientation, and let the rotation group G of the cube act on X in the natural manner. Then two elements of X belong to the same orbit precisely when one is simply a rotation of the other. The number of rotationally distinct colourings is thus the same as the number of orbits and can be found by counting the sizes of the fixed sets for the 24 elements of G.\n\n\nCube with coloured faces\none identity element which leaves all 36 elements of X unchanged\nsix 90-degree face rotations, each of which leaves 33 of the elements of X unchanged\nthree 180-degree face rotations, each of which leaves 34 of the elements of X unchanged\neight 120-degree vertex rotations, each of which leaves 32 of the elements of X unchanged\nsix 180-degree edge rotations, each of which leaves 33 of the elements of X unchanged\nA detailed examination of these automorphisms may be found here.\n\nThe average fix size is thus\n\n1\n24\n(\n3\n6\n+\n6\n⋅\n3\n3\n+\n3\n⋅\n3\n4\n+\n8\n⋅\n3\n2\n+\n6\n⋅\n3\n3\n)\n=\n57.\n{\\frac  {1}{24}}\\left(3^{6}+6\\cdot 3^{3}+3\\cdot 3^{4}+8\\cdot 3^{2}+6\\cdot 3^{3}\\right)=57.\nHence there are 57 rotationally distinct colourings of the faces of a cube in three colours. In general, the number of rotationally distinct colorings of the faces of a cube in n colors is given by\n\n1\n24\n(\n�\n6\n+\n3\n�\n4\n+\n12\n�\n3\n+\n8\n�\n2\n)\n.\n{\\frac  {1}{24}}\\left(n^{6}+3n^{4}+12n^{3}+8n^{2}\\right).\n8 Queens Puzzle\nIn the eight queens puzzle there are 92 solutions, of which 12 fundamental solutions are distinct up to rotation and reflection of the board.

        "answer": "It enables them to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation.",
        "evidence": "Learning natural language generation (NLG) models heavily relies on annotated training data. However, most available datasets are collected in a single language (typically English), which restricts deploying the applications to other languages. In this work, we aim at transferring the supervision of a monolingual NLG dataset to unseen languages, so that we can boost performance for the low-resource settings.\nVarious methods have been proposed over the years to learn universal cross-lingual word embeddings BIBREF0, BIBREF1, BIBREF2 or sentence encoders BIBREF3, BIBREF4, BIBREF5, which tries to encode multilingual texts into a single shared vector space. Despite achieving promising results on cross-lingual classification problems, cross-lingual pre-trained models purposed for NLG tasks remains relatively understudied.\nThe cross-lingual generation problem is challenging due to the following reasons. First, it requires the models to understand multilingual input texts, and generate multilingual target sequences. So both encoder and decoder should be pre-trained together. Second, the many-to-many nature of cross-lingual NLG increases language pairs with the square of the number of languages. Third, the prediction space of cross-lingual NLG is much larger than classification tasks, which makes the knowledge transfer of decoders quite critical.\nPrevious work mainly relies on machine translation (MT) systems to map texts to different languages. The first strand of research directly uses MT in a pipeline manner BIBREF6. For example, the input written in other languages is first translated to English, and fed into the NLG model that is trained by English data. Then the generated English text is translated back to the target language. Another strand of work employs MT to generate pseudo training data for other language pairs that are lack of annotations BIBREF7, BIBREF8. However, such methods have to use multiple MT systems, which renders them suffering from error propagation. Moreover, because the pipeline-based methods do not explicitly share the same parameter space across the languages, we can not directly transfer the task-specific supervision to other low-resource languages.\nIn this paper, we propose a cross-lingual pre-trained model (named as Xnlg) in order to transfer monolingual NLG supervision to other pre-trained languages by fine-tuning. Specifically, Xnlg shares the same sequence-to-sequence model across languages, and is pre-trained with both monolingual and cross-lingual objectives. The model not only learns to understand multilingual input, but also is able to generate specific languages by conditioning on the encoded semantics. Figure FIGREF2 demonstrates how to use Xnlg to perform cross-lingual transfer for downstream tasks. The proposed model enables us to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation. Besides, we explore several fine-tuning strategies to make a compromise between cross-lingual ability and task ability. In addition, we introduce two cross-lingual NLG datasets (i.e., question generation, and abstractive summarization) for evaluation, which includes three languages, namely English, Chinese, and French. Experimental results on the NLG tasks show that Xnlg achieves competitive performance compared with the machine-translation-based pipeline model in zero-shot cross-lingual settings.\nThe proposed model enables us to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation.",

        "evidence": "There are many modern variations of gazpacho with avocados, cucumbers, parsley, strawberries, watermelon, grapes, meat stock, seafood, and other ingredients instead of tomatoes and bread. The ingredients, texture, and thickness of gazpacho vary regionally and between different cooks. Similar cold raw soups such as arjamolho in Portugal, porra antequerana and ajoblanco, are also popular in Andalusia, although not as widespread as gazpacho. Gazpacho and salmorejo are especially similar since they are both tomato-based cold soups that are widely popular in Spain; the main difference between gazpacho and salmorejo is the culinary technique used since gazpacho is a soup whereas salmorejo is an emulsion. In addition, while both dishes share the main ingredients of tomato, olive oil, bread, and garlic, gazpacho can also be prepared with cucumber, peppers, and vinegar, whereas salmorejo cannot. The original recipe using bread, water, vinegar, oil, and salt is traditional in the Iberian Peninsula, perhaps going back to Roman times. Every central and southern region has its own variety. The humble gazpacho became a very deeply rooted food for peasants and shepherds in Spain. The basic gazpacho gave rise to many variants, some also called gazpacho, others not; some authors have tried to classify all these variations. Gazpachos may be classified by colour: the most usual red ones (which contain tomato), white ones (which contain no tomato, but include dried fruits), and green ones (which are white but contain some spices that make them green). These variants have their basic ingredients in common, including garlic paste which works as an emulsifier, bread, olive oil, vinegar and salt. In addition to the traditional ingredients, red fruits such as strawberries, muskmelon, etc., may be added, making the gazpacho a bit sweeter. Gazpacho may be served as a starter, main dish, or tapa.\n\nA popular variation comes from the town of Rota in the province of Cádiz. During times of drought, there was not enough water to make gazpacho; thus, arranque has the same ingredients as gazpacho, but requires less water and bread, making it a sort of cream. Some people add more bread until it takes on the consistency of a dip.\n\nIn Extremadura, gazpachos are a kind of purée or thick gazpacho known as cojondongo, or cojondongo del gañán, made of breadcrumbs, garlic, oil, and vinegar, then topped with chopped onions, tomato and peppers.\n\nGazpacho manchego, as its name implies, is made in the east region of La Mancha, in Albacete and nearby areas, and is popular in other areas in the center and southwest of the country. It is a meat stew, whose main ingredients are small game animals or birds such as rabbit, hare, quail, or pigeon, and flatbread, and may include garlic, tomatoes, and mushrooms. It is cooked in a cauldron and served hot. Another well-known variant in La Mancha is gazpacho de pastor or galiano. Some other hot meat or fish dishes from other regions are called gazpacho (gazpacho jumillano, gazpacho de Yecla, gazpacho de Requena, etc.)\n\nGazpacho is often eaten during the very hot and dry summers in Castilla y León. The gazpacho made in La Moraña in the province of Ávila has large pieces of vegetables floating in a watery soup.\n\nGazpacho manchego, despite its name, is a meat stew, served hot, not a variation on the cold vegetable soup.",

        "answer": "The core of comparative genome analysis is the establishment of the correspondence between genes (orthology analysis) or other genomic features in different organisms. It is these intergenomic maps that make it possible to trace the evolutionary processes responsible for the divergence of two genomes. A multitude of evolutionary events acting at various organizational levels shape genome evolution. At the lowest level, point mutations affect individual nucleotides. At a higher level, large chromosomal segments undergo duplication, lateral transfer, inversion, transposition, deletion and insertion. Ultimately, whole genomes are involved in processes of hybridization, polyploidization and endosymbiosis, often leading to rapid speciation. The complexity of genome evolution poses many exciting challenges to developers of mathematical models and algorithms, who have recourse to a spectrum of algorithmic, statistical and mathematical techniques, ranging from exact, heuristics, fixed parameter and approximation algorithms for problems based on parsimony models to Markov chain Monte Carlo algorithms for Bayesian analysis of problems based on probabilistic models.\n\nMany of these studies are based on the detection of sequence homology to assign sequences to protein families.",

In this paper, we investigate how appropriate such data is for modeling natural dialog, and introduce Interview, a new high-quality large-scale open-domain conversational dataset grounded in interview settings with annotations for specific speaker roles.\nWe compare the performance of state-of-the-art language models fine-tuned on Interview and other popular conversational datasets, demonstrating that Interview contains more complex dialog and better models the characteristics of natural spoken conversations. Our dataset is an order of magnitude larger than existing high-quality natural dialog datasets and contains speaker role annotations for each turn, facilitating the development of conversational agents and assistive systems for settings involving specific speaker roles, such as doctor-patient interviews or hosted talk shows.\nIn particular, we explore the tasks of role modeling in media dialog and role change detection on Interview and find that leveraging role information can enable more nuanced, on-topic and natural dialog generation, as well as improve role change classification performance.\nIn summary, we present Interview, the first large-scale open-domain media dialog dataset. We explore two tasks for which it serves as a promising benchmark dataset: speaker role modeling and speaker change detection. We build simple yet strong models to show quantitatively that role labels from Interview improve performance on such tasks.

        "question": "Based on what principles do they design verb patterns?",
        "answer": "Idiom principle and openchoice principle.",
        "evidence": "Verb is crucial in sentence understanding BIBREF0 , BIBREF1 . A major issue of verb understanding is polysemy BIBREF2 , which means that a verb has different semantics or senses when collocating with different objects. In this paper, we only focus on verbs that collocate with objects. As illustrated in Example SECREF1 , most verbs are polysemous. Hence, a good semantic representation of verbs should be aware of their polysemy.\nExample 1 (Verb Polysemy) eat has the following senses:\nMany typical verb representations, including FrameNet BIBREF3 , PropBank BIBREF4 , and VerbNet BIBREF5 , describe verbs' semantic roles (e.g. ingestor and ingestibles for “eat”). However, semantic roles in general are too coarse to differentiate a verb's fine-grained semantics. A verb in different phrases can have different semantics but similar roles. In Example SECREF1 , both “eat”s in “eat breakfast” and “eat apple” have ingestor. But they have different semantics.\nThe unawareness of verbs' polysemy makes traditional verb representations unable to fully understand the verb in some applications. In sentence I like eating pitaya, people directly know “pitaya” is probably one kind of food since eating a food is the most fundamental semantic of “eat”. This enables context-aware conceptualization of pitaya to food concept. But by only knowing pitaya's role is the “ingestibles”, traditional representations cannot tell if pitaya is a food or a meal.\nVerb Patterns We argue that verb patterns (available at http://kw.fudan.edu.cn/verb) can be used to represent more fine-grained semantics of a verb. We design verb patterns based on two word collocations principles proposed in corpus linguistics BIBREF6 : idiom principle and open-choice principle. Following the principles, we designed two types of verb patterns.\nAccording to the above definitions, we use verb patterns to represent the verb's semantics. Phrases assigned to the same pattern have similar semantics, while those assigned to different patterns have different semantics. By verb patterns, we know the “pitaya” in I like eating pitaya is a food by mapping “eat pitaya” to “eat $ INLINEFORM0 food”. On the other hand, idiom patterns specify which phrases should not be conceptualized. We list verb phrases from Example SECREF1 and their verb patterns in Table TABREF7 . And we will show how context-aware conceptualization benefits from our verb patterns in the application section.\nThus, our problem is how to generate conceptualized patterns and idiom patterns for verbs. We use two public data sets for this purpose: Google Syntactic N-Grams (http://commondatastorage.googleapis.com/books/syntactic -ngrams/index.html) and Probase BIBREF7 . Google Syntactic N-grams contains millions of verb phrases, which allows us to mine rich patterns for verbs. Probase contains rich concepts for instances, which enables the conceptualization for objects. Thus, our problem is given a verb INLINEFORM0 and a set of its phrases, generating a set of patterns (either conceptualized patterns or idiom patterns) for INLINEFORM1 . However, the pattern generation for verbs is non-trivial. In general, the most critical challenge we face is the trade-off between generality and specificity of the generated patterns, as explained below.\nWe design verb patterns based on two word collocations principles proposed in corpus linguistics (Sinclair 1991): idiom principle and openchoice principle.",

        "answer": "A method that can turn popular coreference evaluation metrics into differentiable functions of model parameters.",
        "evidence": "Coreference resolution is the task of identifying all mentions which refer to the same entity in a document. It has been shown beneficial in many natural language processing (NLP) applications, including question answering BIBREF0 and information extraction BIBREF1 , and often regarded as a prerequisite to any text understanding task.\nCoreference resolution can be regarded as a clustering problem: each cluster corresponds to a single entity and consists of all its mentions in a given text. Consequently, it is natural to evaluate predicted clusters by comparing them with the ones annotated by human experts, and this is exactly what the standard metrics (e.g., MUC, B INLINEFORM0 , CEAF) do. In contrast, most state-of-the-art systems are optimized to make individual co-reference decisions, and such losses are only indirectly related to the metrics.\nOne way to deal with this challenge is to optimize directly the non-differentiable metrics using reinforcement learning (RL), for example, relying on the REINFORCE policy gradient algorithm BIBREF2 . However, this approach has not been very successful, which, as suggested by clark-manning:2016:EMNLP2016, is possibly due to the discrepancy between sampling decisions at training time and choosing the highest ranking ones at test time. A more successful alternative is using a `roll-out' stage to associate cost with possible decisions, as in clark-manning:2016:EMNLP2016, but it is computationally expensive. Imitation learning BIBREF3 , BIBREF4 , though also exploiting metrics, requires access to an expert policy, with exact policies not directly computable for the metrics of interest.\nIn this work, we aim at combining the best of both worlds by proposing a simple method that can turn popular coreference evaluation metrics into differentiable functions of model parameters. As we show, this function can be computed recursively using scores of individual local decisions, resulting in a simple and efficient estimation procedure. The key idea is to replace non-differentiable indicator functions (e.g. the member function INLINEFORM0 ) with the corresponding posterior probabilities ( INLINEFORM1 ) computed by the model. Consequently, non-differentiable functions used within the metrics (e.g. the set size function INLINEFORM2 ) become differentiable ( INLINEFORM3 ). Though we assume that the scores of the underlying statistical model can be used to define a probability model, we show that this is not a serious limitation. Specifically, as a baseline we use a probabilistic version of the neural mention-ranking model of P15-1137, which on its own outperforms the original one and achieves similar performance to its global version BIBREF5 . Importantly when we use the introduced differentiable relaxations in training, we observe a substantial gain in performance over our probabilistic baseline. Interestingly, the absolute improvement (+0.52) is higher than the one reported in clark-manning:2016:EMNLP2016 using RL (+0.05) and the one using reward rescaling (+0.37). This suggests that our method provides a viable alternative to using RL and reward rescaling.\nThe outline of our paper is as follows: we introduce our neural resolver baseline and the B INLINEFORM0 and LEA metrics in Section SECREF2 . Our method to turn a mention ranking resolver into an entity-centric resolver is presented in Section SECREF3 , and the proposed differentiable relaxations in Section SECREF4 . Section SECREF5 shows our experimental results.\nIn this work, we aim at combining the best of both worlds by proposing a simple method that can turn popular coreference evaluation metrics into differentiable functions of model parameters.",

Further analysis using black-box probes confirms that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo's embeddings.

        "evidence": "For evaluating topics with automatic quality measures, we used several English text collections and one Russian collection (Table TABREF7 ). We experiment with three thesauri: WordNet (155 thousand entries), information-retrieval thesaurus of the European Union EuroVoc (15161 terms), and Russian thesaurus RuThes (115 thousand entries) BIBREF19 .\nAt the preprocessing step, documents were processed by morphological analyzers. Also, we extracted noun groups as described in BIBREF16 . As baselines, we use the unigram LDA topic model and LDA topic model with added 1000 ngrams with maximal NC-value BIBREF20 extracted from the collection under analysis.\nAs it was found before BIBREF14 , BIBREF16 , the addition of ngrams without accounting relations between their components considerably worsens the perplexity because of the vocabulary growth (for perplexity the less is the better) and practically does not change other automatic quality measures (Table 2).\nWe add the Wordnet data in the following steps. At the first step, we include WordNet synonyms (including multiword expressions) into the proposed similarity sets (LDA-Sim+WNsyn). At this step, frequencies of synonyms found in the same document are summed up in process LDA topic learning as described in Algorithm SECREF3 . We can see that the kernel uniqueness becomes very low, topics are very close to each other in content (Table 2: LDA-Sim+WNsyn). At the second step, we add word direct relatives (hyponyms, hypernyms, etc.) to similarity sets. Now the frequencies of semantically related words are added up enhancing the contribution into all topics of the current document.\nThe Table 2 shows that these two steps lead to great degradation of the topic model in most measures in comparison to the initial unigram model: uniqueness of kernels abruptly decreases, perplexity at the second step grows by several times (Table 2: LDA-Sim+WNsynrel). It is evident that at this step the model has a poor quality. When we look at the topics, the cause of the problem seems to be clear. We can see the overgeneralization of the obtained topics. The topics are built around very general words such as \"person\", \"organization\", \"year\", etc. These words were initially frequent in the collection and then received additional frequencies from their frequent synonyms and related words.\nThen we suppose that these general words were used in texts to discuss specific events and objects, therefore, we change the constructions of the similarity sets in the following way: we do not add word hyponyms to its similarity set. Thus, hyponyms, which are usually more specific and concrete, should obtain additional frequencies from upper synsets and increase their contributions into the document topics. But the frequencies and contribution of hypernyms into the topic of the document are not changed. And we see the great improvement of the model quality: the kernel uniqueness considerably improves, perplexity decreases to levels comparable with the unigram model, topic coherence characteristics also improve for most collections (Table 2:LDA-Sim+WNsynrel/hyp).\nWe further use the WordNet-based similarity sets with n-grams having the same components as described in BIBREF16 . All measures significantly improve for all collections (Table 2:LDA-Sim+WNsr/hyp+Ngrams). At the last step, we try to apply the same approach to ngrams that was previously utilized to hyponym-hypernym relations: frequencies of shorter ngrams and words are summed to frequencies of longer ngrams but not vice versa. In this case we try to increase the contribution of more specific longer ngrams into topics. It can be seen (Table 2) that the kernel uniqueness grows significantly, at this step it is 1.3-1.6 times greater than for the baseline models achieving 0.76 on the ACL collection (Table 2:LDA-Sim+WNsr/hyp+Ngrams/l).\nAt the second series of the experiments, we applied EuroVoc information retrieval thesaurus to two European Union collections: Europarl and JRC. In content, the EuroVoc thesaurus is much smaller than WordNet, it contains terms from economic and political domains and does not include general abstract words. The results are shown in Table 3. It can be seen that inclusion of EuroVoc synsets improves the topic coherence and increases kernel uniqueness (in contrast to results with WordNet). Adding ngrams further improves the topic coherence and kernel uniqueness.\nAt last we experimented with the Russian banking collection and utilized RuThes thesaurus. In this case we obtained improvement already on RuThes synsets and again adding ngrams further improved topic coherence and kernel uniqueness (Table 4).\nIt is worth noting that adding ngrams sometimes worsens the TC-NPMI measure, especially on the JRC collection. This is due to the fact that in these evaluation frameworks, the topics' top elements contain a lot of multiword expressions, which rarely occur in Wikipedia, used for the coherence calculation, therefore the utilized automatic coherence measures can have insufficient evidence for correct estimates.\nWe add the Wordnet data in the following steps. At the first step, we include WordNet synonyms (including multiword expressions) into the proposed similarity sets (LDASim+WNsyn). At this step, frequencies of synonyms found in the same document are summed up in process LDA topic learning as described in Algorithm 1.We can see that the kernel uniqueness becomes very low, topics are very close to each other in content (Table 2: LDA-Sim+WNsyn).

        "evidence": "Question generation (QG) is the task of generating a question from a reference sentence and a specified answer within the sentence. A major challenge in QG is to identify answer-relevant context words to finish the declarative-to-interrogative sentence transformation. Existing sequence-to-sequence neural models achieve this goal by proximity-based answer position encoding under the intuition that neighboring words of answers are of high possibility to be answer-relevant. However, such intuition may not apply to all cases especially for sentences with complex answer-relevant relations. Consequently, the performance of these models drops sharply when the relative distance between the answer fragment and other non-stop sentence words that also appear in the ground truth question increases. To address this issue, we propose a method to jointly model the unstructured sentence and the structured answer-relevant relation (extracted from the sentence in advance) for question generation. Specifically, the structured answer-relevant relation acts as the to the point context and it thus naturally helps keep the generated question to the point, while the unstructured sentence provides the full information. Extensive experiments show that to the point context helps our question generation model achieve significant improvements on several automatic evaluation metrics. Furthermore, our model is capable of generating diverse questions for a sentence which conveys multiple relations of its answer fragment.\nHowever, such intuition may not apply to all cases especially for sentences with complex answer-relevant relations.

        "question": "What are the pros and cons of charging your Tesla at home?",
        "evidence": "",
        "answer": "The most convenient way to charge your EV is to charge it at home overnight while you sleep. Home chargers tend to be slow chargers which reach around 3.6 - 7 kW, although you can also charge using your home’s plug sockets which charge at speeds of around 2.3 kW. \n\nPros\nCharging your Tesla Model Y at home overnight is probably the cheapest, most cost-efficient way to charge your EV. This is because off-peak energy prices are significantly cheaper than peak charging. Model Ys come with an adapter wire, allowing you to charge your EV using your home's plugs easily. \n\nIf you're interested in charging at home, installing a home charging unit could be worth your time. Over time this could save you money. There are grants available to help you afford a home charger. \n\nThe OZEV Chargepoint Grant is up to £350 or 75% off the fully installed charge point cost if specifics are met. There is also the Scottish EST Domestic Chargepoint Grant which gives you up to £300 and can be used alongside the OZEV Chargepoint Grant.\n\nCons\nHome chargers rarely exceed speeds of 7 kW. This means charging the Tesla Model Y's large battery would take a long time. If you don't invest in a home charging station, it might also be risky to home charge as the 3-pin plug can damage your home's wiring. \n\nIf you choose to charge during the day, it can also get quite expensive and may not compare favourably with public charging stations, despite being much slower.",

Signals sent from the table can be interpreted as additional constraints. In the second scenario we share the decoder between two output channels. The first one samples the target character and the other one predicts the morphological annotation of the character.

The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. The data was first processed into Tensorflow records as the input to the model. The set of hyperparameters which we found optimal after experimenting with different sets are in (Table TABREF10).\nThis set of parameters were chosen as there training performances were better than smaller models on modelling the long sequences of sub-words. We use the Adam optimizer BIBREF16 same as the English BERT. A maximum sequence length of 300 encompasses 98 percent of the training data and also allows us to fit larger models on the GPU card. Hyper-parameter optimization is very difficult in case of these models as they take around 15 days to train given the resources. The hyperparameter choices were therefore more dependant on the original BERT with little tweaks. We assess the training performance of the the model in the (Table TABREF11).\nWhen we train the BERT model we mask some percentage of the input tokens at random, and then predict those masked tokens, this is known as Masked LM. The masked LM loss, refers specifically to the loss when the masked language model predicts on the masked tokens. The masked LM accuracy refers specifically to the accuracy with which the model predicts on the masked tokens. The loss for both the models are far off from the Masked LM loss of the English BERT, key difference being the pre-training data for both the language models are quite different. Google training their model on 3.3 Billion words from BooksCorpus BIBREF17 and the English Wikipedia and our model being trained on 144 million words. Comparing the two Finnish models, the left-marked model has a better training performance than left+right-marked model.\nThe results of the pseudo-perplexity described in the previous section to evaluate the above models on the test data-set is in table (Table TABREF12).The test dataset is of a different context when compared to the training data, and interestingly both the models are quite confident when it comes to the test dataset. The pseudo-perplexity values of left-marked are lower when compared to left-right-marked signifying that it is more confident.\nWe cannot directly compare the perplexity scores BERT model with a unidirectional LSTM model as both are calculated in a different manner. We can experiment to compare it with a Bi-directional LSTM or use a downstreaming task to compare both the performances. We could also randomly mask tokens and then compare the prediction accuracy on the masked tokens.\nAll Transformer-XL experiments are also trained equally for 500K steps. The code was written in Python and we used the PyTorch libraries for model creation. The experiments were trained on a single NVIDIA Tesla V100 32 GB graphic card. Two sets of hyperparameters were chosen to be compared after some initial optimization and are in (Table TABREF14)\nFrom the above parameter choice, we wanted to experiment, whether providing more Segment and Memory length is advantageous (longer context) than a larger model. These parameters where chosen after some hyperparameter optimization. Same as for BERT we use the Adam optimizer, but we also use a cosine annealing learning rate scheduler to speed-up training BIBREF18. The training performance results are in (Table TABREF15)\nAs opposed to BERT, the left+right-marked models have a better training performance than their counterpart. Interestingly the larger model trains much better when compared to providing larger contexts. The same set of parameters for the 32-32 model cannot be replicated for 150-150 model as the latter takes a lot of space on the GPU card. The test set is same as that used with BERT and the results are in (Table TABREF16). The test performance is similar to that of the training performance with left-right-marked large model(32-32) performing the best. We can directly compare the perplexity scores with the previous best BIBREF19 as both are unidirectional models, Transformer-XL model has outperformed the latter by 27%.\nTransformer-XL and BERT both have low perplexity and pseudo-perplexity scores, but both cannot be directly compared as they are calculated quite differently (Eq.DISPLAY_FORM4, Eq.DISPLAY_FORM6). The dramatically low scores of BERT indicate that per word predicted probability is higher than that of a uni-directional model. Thus the predicted word probability distribution is much sharper when compared to the XL model probability distribution. At this point, we cannot say which model architecture has performed better- BERT or Transformer-XL, despite both of them achieving good low perplexity scores. We would need to experiment with a downstreaming task in-order to fairly compare model performances.\nAt this point, we cannot say which model architecture has performed better- BERT or Transformer-XL, despite both of them achieving good low perplexity scores.

The KBQA system in the figure performs two key tasks: (1) entity linking, which links $n$ -grams in questions to KB entities, and (2) relation detection, which identifies the KB relation(s) a question refers to.\nThe main focus of this work is to improve the relation detection subtask and further explore how it can contribute to the KBQA system. Although general relation detection methods are well studied in the NLP community, such studies usually do not take the end task of KBQA into consideration. As a result, there is a significant gap between general relation detection studies and KB-specific relation detection. First, in most general relation detection tasks, the number of target relations is limited, normally smaller than 100. In contrast, in KBQA even a small KB, like Freebase2M BIBREF2 , contains more than 6,000 relation types. Second, relation detection for KBQA often becomes a zero-shot learning task, since some test instances may have unseen relations in the training data. For example, the SimpleQuestions BIBREF2 data set has 14% of the golden test relations not observed in golden training tuples. Third, as shown in Figure 1 (b), for some KBQA tasks like WebQuestions BIBREF0 , we need to predict a chain of relations instead of a single relation. This increases the number of target relation types and the sizes of candidate relation pools, further increasing the difficulty of KB relation detection. Owing to these reasons, KB relation detection is significantly more challenging compared to general relation detection tasks.\nThis paper improves KB relation detection to cope with the problems mentioned above. First, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching. Second, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations. Third, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information. Finally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching.\nIn order to assess how the proposed improved relation detection could benefit the KBQA end task, we also propose a simple KBQA implementation composed of two-step relation detection. Given an input question and a set of candidate entities retrieved by an entity linker based on the question, our proposed relation detection model plays a key role in the KBQA process: (1) Re-ranking the entity candidates according to whether they connect to high confident relations detected from the raw question text by the relation detection model. This step is important to deal with the ambiguities normally present in entity linking results. (2) Finding the core relation (chains) for each topic entity selection from a much smaller candidate entity set after re-ranking. The above steps are followed by an optional constraint detection step, when the question cannot be answered by single relations (e.g., multiple entities in the question). Finally the highest scored query from the above steps is used to query the KB for answers.\nOur main contributions include: (i) An improved relation detection model by hierarchical matching between questions and relations with residual learning; (ii) We demonstrate that the improved relation detector enables our simple KBQA system to achieve state-of-the-art results on both single-relation and multi-relation KBQA tasks.\nFinally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching.",

        "question": "How is education in Singapore",
        "evidence": "Education in Singapore is managed by the Ministry of Education (MOE). It controls the development and administration of state schools receiving taxpayers' funding, but also has an advisory and supervisory role in respect of private schools. For both private and state schools, there are variations in the extent of autonomy in their curriculum, scope of taxpayers' aid and funding, tuition burden on the students, and admission policy.",
        "answer": "Education spending usually makes up about 20 per cent of the annual national budget, which subsidises state education and government-assisted private education for Singaporean citizens and funds the Edusave programme. Non-citizens bear significantly higher costs of educating their children in Singapore government and government-aided schools. In 2000, the Compulsory Education Act codified compulsory education for children of primary school age (excepting those with disabilities), and made it a criminal offence for parents to fail to enroll their children in school and ensure their regular attendance. Exemptions are allowed for homeschooling or full-time religious institutions, but parents must apply for exemption from the Ministry of Education and meet a minimum benchmark.\n\nThe main language of instruction in Singapore is English, which was officially designated the first language within the local education system in 1987. English is the first language learned by half the children by the time they reach preschool age and becomes the primary medium of instruction by the time they reach primary school. Although Malay, Mandarin and Tamil are also official languages, English is the language of instruction for nearly all subjects except the official Mother Tongue languages and the literatures of those languages; these are generally not taught in English, although there is provision for the use of English at the initial stages. Certain schools, such as secondary schools under the Special Assistance Plan (SAP), encourage a richer use of the mother tongue and may occasionally teach subjects in Mandarin Chinese.\n\nSingapore's education system has been consistently ranked as one of the highest in the world by the OECD. It is believed that this comes from the style of teaching that is implemented in Singapore. Teachers focus on making sure that each of their students thoroughly move through the syllabus before moving on. By doing this teachers in Singapore teach a much more narrow but deeper type of instruction. Furthermore, it has been described as \"world-leading\" and in 2010 was among those picked out for commendation by the Conservative former UK Education Secretary Michael Gove. According to PISA, an influential worldwide study on educational systems, Singapore has the highest performance in international education and tops in global rankings. In 2020, Singaporean students made up half of the perfect scorers in the International Baccalaureate (IB) examinations worldwide.",

        "answer": "One major obstacle in KRR is the creation of large-scale knowledge bases with high quality.",
        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nOne major obstacle in KRR is the creation of large-scale knowledge bases with high quality.",

        "evidence": "Automatic Text Summarization deals with the task of condensing documents into a summary, whose level is similar to a human-generated summary. It is mostly distributed into two distinct domains, i.e., Abstractive Summarization and Extractive Summarization. Abstractive summarization( Dejong et al. ,1978) involves models to deduce the crux of the document. It then presents a summary consisting of words and phrases that were not there in the actual document, sometimes even paraphrasing BIBREF1 . A state of art method proposed by Wenyuan Zeng BIBREF2 produces such summaries with length restricted to 75. There have been many recent developments that produce optimal results, but it is still in a developing phase. It highly relies on natural language processing techniques, which is still evolving to match human standards. These shortcomings make abstractive summarization highly domain selective. As a result, their application is skewed to the areas where NLP techniques have been superlative. Extractive Summarization, on the other hand, uses different methods to identify the most informative/dominant sentences through the text, and then present the results, ranking them accordingly. In this paper, we have proposed two novel stand-alone summarization methods.The first method is based on Glove Model BIBREF3 ,and other is based on Facebook's InferSent BIBREF4 . We have also discussed how we can effectively subdue shortcomings of one model by using it in coalition with models which capture the view that other faintly held.\nIn this paper, we have proposed two novel stand-alone summarization methods.The first method is based on Glove Model,and other is based on Facebook's InferSent.",

        "evidence": "Keyphrases are single or multi-word lexical units that best summarise a document BIBREF0. As such, they are of great importance for indexing, categorising and browsing digital libraries BIBREF1. Yet, very few documents have keyphrases assigned, thus raising the need for automatic keyphrase generation systems. This task falls under the task of automatic keyphrase extraction which can also be the subtask of finding keyphrases that only appear in the input document. Generating keyphrases can be seen as a particular instantiation of text summarization, where the goal is not to produce a well-formed piece of text, but a coherent set of phrases that convey the most salient information. Those phrases may or may not appear in the document, the latter requiring some form of abstraction to be generated. State-of-the-art systems for this task rely on recurrent neural networks BIBREF2, BIBREF3, BIBREF4, and hence require large amounts of annotated training data to achieve good performance. As gold annotated data is expensive and difficult to obtain BIBREF5, previous works focused on readily available scientific abstracts and used author-assigned keyphrases as a proxy for expert annotations. However, this poses two major issues: 1) neural models for keyphrase generation do not generalize well across domains, thus limiting their use in practice; 2) author-assigned keyphrases exhibit strong consistency issues that negatively impacts the model's performance. There is therefore a great need for annotated data from different sources, that is both sufficiently large to support the training of neural-based models and that comprises gold-standard labels provided by experts. In this study, we address this need by providing KPTimes, a dataset made of 279 923 news articles that comes with editor-assigned keyphrases.\nOnline news are particularly relevant to keyphrase generation since they are a natural fit for faceted navigation BIBREF6 or topic detection and tracking BIBREF7. Also, and not less importantly, they are available in large quantities and are sometimes accompanied by metadata containing human-assigned keyphrases initially intended for search engines. Here, we divert these annotations from their primary purpose, and use them as gold-standard labels to automatically build our dataset. More precisely, we collect data by crawling selected news websites and use heuristics to draw texts paired with gold keyphrases. We then explore the resulting dataset to better understand how editors tag documents, and how these expert annotations differ from author-assigned keyphrases found in scholarly documents. Finally, we analyse the performance of state-of-the-art keyphrase generation models and investigate their transferability to the news domain and the impact of domain shift.\nMore precisely, we collect data by crawling selected news websites and use heuristics to draw texts paired with gold keyphrases.",

Gaining an early following as one of the first British psychedelic groups, they were distinguished by their extended compositions, sonic experimentation, philosophical lyrics and elaborate live shows. They became a leading band of the progressive rock genre, cited by some as the greatest progressive rock band of all time.\n\nPink Floyd were founded in 1965 by Syd Barrett (guitar, lead vocals), Nick Mason (drums), Roger Waters (bass guitar, vocals), and Richard Wright (keyboards, vocals). Under Barrett's leadership, they released two charting singles and the successful debut album The Piper at the Gates of Dawn (1967). The guitarist and vocalist David Gilmour joined in January 1968; Barrett left in April 1968 due to deteriorating mental health. Waters became the primary lyricist and thematic leader, devising the concepts behind Pink Floyd's most successful albums, The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977) and The Wall (1979). The musical film based on The Wall, Pink Floyd – The Wall (1982), won two BAFTA Awards. Pink Floyd also composed several film scores.\n\nFollowing personal tensions, Wright left Pink Floyd in 1981, followed by Waters in 1985. Gilmour and Mason continued as Pink Floyd, rejoined later by Wright. They produced the albums A Momentary Lapse of Reason (1987) and The Division Bell (1994), backed by major tours, before entering a long hiatus. In 2005, all but Barrett reunited for a performance at the global awareness event Live 8. Barrett died in 2006, and Wright in 2008. The last Pink Floyd studio album, The Endless River (2014), was based on unreleased material from the Division Bell recording sessions. In 2022, Gilmour and Mason reformed Pink Floyd to release the song \"Hey, Hey, Rise Up!\" in protest of the Russo-Ukrainian War.\n\nBy 2013, Pink Floyd had sold more than 250 million records worldwide, making them one of the best-selling music artists of all time. The Dark Side of the Moon and The Wall were inducted into the Grammy Hall of Fame, and these albums and Wish You Were Here are among the best-selling albums of all time. Four Pink Floyd albums topped the US Billboard 200, and five topped the UK Albums Chart. Pink Floyd's hit singles include \"See Emily Play\" (1967), \"Money\" (1973), \"Another Brick in the Wall, Part 2\" (1979), \"Not Now John\" (1983), \"On the Turning Away\" (1987) and \"High Hopes\" (1994).

        "evidence": "According to The National Institute on Deafness, one in thousand infants is born deaf. An additional one to six per thousand are born with hearing loss at different levels BIBREF0. Sign language is commonly used by Deaf and Hard-of-Hearing (DHH) persons to communicate via hand gestures. An automatic sign language recognizer enables an ASL user to translate the sign language to written text or speech, allowing them to communicate with people who are not familiar with ASL. There is a tremendous rise in the popularity of personal digital assistants; available on user's personal and wearable devices (Google Now, Amazon Alexa and Apple Siri, etc.) and also in the form of standalone devices (Amazon Echo and Google Home smart speakers). These devices are primarily controlled through voice, and hence, their functionality is not readily available to DHH users. An automatic sign recognizer can also enable the interaction between a DHH user and a digital assistant.\nMost current systems have capability of ASL recognition with RGB video data BIBREF1, BIBREF2, BIBREF3. An ASL sign is performed by a combination of hand gestures, facial expressions and postures of the body. Sequential motion of specific body locations (such as hand-tip, neck and arm) provide informative cues about a sign. Using video data, it is difficult to extract different body locations and associated motion sequences from a series of RGB frames. Microsoft Kinect is a 3D camera sensor which can use the depth information of a person to capture 3D coordinates of his/her body location across a video. This sequence of 3D body location is referred by skeletal data BIBREF4. To the best of our knowledge, there is no publicly available skeletal dataset in literature for ASL recognition.\nWith skeletal data, an ASL sign can be seen as a sequence of 3D coordinates or a 3D time series BIBREF5. Recurrent neural networks (RNN) have shown strong performance for sequential modeling BIBREF6. In this work, we investigate the impact of RGB video data in recognition accuracy when combined with skeletal data. We also propose a combined RNN network with a simple spatial data augmentation technique. In summary, the contributions of this work are:\nWe propose an RNN architecture with a novel spatial data augmentation technique.\nWe propose an architecture which uses both RGB and skeletal data to improve recognition accuracy.\nWe introduce and publicly release a multi–modal dataset for ASL called GMU-ASL51.\nWe propose an architecture which uses both RGB and skeletal data to improve recognition accuracy.",

        "answer": "Their single model.",
        "evidence": "Machine reading comprehension and question answering has becomes a crucial application problem in evaluating the progress of AI system in the realm of natural language processing and understanding BIBREF0 . The computational linguistics communities have devoted significant attention to the general problem of machine reading comprehension and question answering.\nHowever, most of existing reading comprehension tasks only focus on shallow QA tasks that can be tackled very effectively by existing retrieval-based techniques BIBREF1 . For example, recently we have seen increased interest in constructing extractive machine reading comprehension datasets such as SQuAD BIBREF2 and NewsQA BIBREF3 . Given a document and a question, the expected answer is a short span in the document. Question context usually contains sufficient information for identifying evidence sentences that entail question-answer pairs. For example, 90.2% questions in SQuAD reported by Min BIBREF4 are answerable from the content of a single sentence. Even in some multi-turn conversation tasks, the existing models BIBREF5 mostly focus on retrieval-based response matching.\nIn this paper, we focus on multiple-choice reading comprehension datasets such as RACE BIBREF6 in which each question comes with a set of answer options. The correct answer for most questions may not appear in the original passage which makes the task more challenging and allow a rich type of questions such as passage summarization and attitude analysis. This requires a more in-depth understanding of a single document and leverage external world knowledge to answer these questions. Besides, comparing to traditional reading comprehension problem, we need to fully consider passage-question-answer triplets instead of passage-question pairwise matching.\nIn this paper, we propose a new model, Dual Co-Matching Network, to match a question-answer pair to a given passage bidirectionally. Our network leverages the latest breakthrough in NLP: BERT BIBREF7 contextual embedding. In the origin BERT paper, the final hidden vector corresponding to first input token ([CLS]) is used as the aggregation representation and then a standard classification loss is computed with a classification layer. We think this method is too rough to handle the passage-question-answer triplet because it only roughly concatenates the passage and question as the first sequence and uses question as the second sequence, without considering the relationship between the question and the passage. So we propose a new method to model the relationship among the passage, the question and the candidate answer.\nFirstly we use BERT as our encode layer to get the contextual representation of the passage, question, answer options respectively. Then a matching layer is constructed to get the passage-question-answer triplet matching representation which encodes the locational information of the question and the candidate answer matched to a specific context of the passage. Finally we apply a hierarchical aggregation method over the matching representation from word-level to sequence-level and then from sequence level to document-level. Our model improves the state-of-the-art model by 2.6 percentage on the RACE dataset with BERT base model and further improves the result by 3 percentage with BERT large model.\nEspecially, our single model performs even better than human turkers on the RACE full dataset, which is the first milestone achievement ever since the RACE challenge has been set up.",

        "answer": "Most importantly, a person should get married when they find the right person. But assuming one has found the right person, there are comparative advantages and disadvantages to marrying at a young age or an older age. Men have the advantage of not needing to worry about the 'biological clock' - unlike women, their reproductive age can extend into quite a late age, whereas women typically lose the ability to reproduce once they hit around the age of 40. An advantage of having children when one is young is that a man will have more energy and physical dexterity to be able to engage in physical activities with his children, like camping, biking, hiking, sports, skiing, etc. Bending over to change diapers will not be as painful on the back and knees. As a younger man, travel with children may be less discomforting. As an older man, one might have more time or flexibility of time to spend with one's children. An older man may also have greater financial resources to help make child raising easier. For example, an older man might have a larger house, or a greater ability to afford in-house child care. On the other hand, there are studies that show having an older father may increase the odds of a child having autism or attention deficit disorder. Anecdotally, it seems people who marry at a young age are more likely to divorce. But perhaps having two marriages, one when one is young and another when one is older, is not a bad thing. Men have the advantage of being able to sire two sets of children at different times in their lives, making this possible. But ultimately the decision should be based on whether or not you have met the person you know without a doubt you want to spend the rest of your life with. If you have found that person, you should stay with them.",

        "evidence": "First, we evaluated the standard HMM model with an uninformative prior (this will be our baseline) for the two different input features: MFCC (and derivatives) and MBN. Results are shown in Table TABREF20 . Surprisingly, the MBN features perform relatively poorly compared to the standard MFCC. These results are contradictory to those reported in BIBREF3 . Two factors may explain this discrepancy: the Mboshi5k data being different from the training data of the MBN neural network, the neural network may not generalize well. Another possibility may be that the initialization scheme of the model is not suitable for this type of features. Indeed, Variational Bayesian Inference algorithm converges only to a local optimum of the objective function and is therefore dependent of the initialization. We believe the second explanation is the more likely since, as we shall see shortly, the best results in term of word segmentation and NMI are eventually obtained with the MBN features when the inference is done with the informative prior. Next, we compared the HMM and the SVAE models when trained with an uninformative prior (lines with \"Inf. Prior\" set to \"no\" in Table TABREF23 ). The SVAE significantly improves the NMI and the precision showing that it extracts more consistent units than the HMM model. However, it also degrades the segmentation in terms of recall. We further investigated this behavior by looking at the duration of the units found by both models compared to the true phones (Table TABREF22 ). We observe that the SVAE model favors longer units than the HMM model hence leading to fewer boundaries and consequently smaller recall.\nWe then evaluated the effect of the informative prior on the acoustic unit discovery (Table TABREF23 ). On all 4 combinations (2 features sets INLINEFORM0 2 models) we observe an improvement in terms of precision and NMI but a degradation of the recall. This result is encouraging since the informative prior was trained on English data (TIMIT) which is very different from Mboshi. Indeed, this suggests that even speech from an unrelated language can be of some help in the design of an ASR for a very low resource language. Finally, similarly to the SVAE/HMM case described above, we found that the degradation of the recall is due to longer units discovered for models with an informative prior (numbers omitted due to lack of space).\nWord discovery results are given in Table TABREF21 for the Boundary metric BIBREF20 , BIBREF21 . We observe that i) the best word boundary detection (F-score) is obtained with MBN features, an informative prior and the SVAE model; this confirms the results of table TABREF23 and shows that better AUD leads to better word segmentation ii) word segmentation from AUD graph Lattices is slightly better than from flat sequences of AUD symbols (1-best); iii) our results outperform a pure speech based baseline based on segmental DTW BIBREF22 (F-score of 19.3% on the exact same corpus).\nFirst, we evaluated the standard HMM model with an uninformative prior (this will be our baseline) for the two different input features: MFCC (and derivatives) and MBN.",

        "answer": "Because the KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures.",
        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nKALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures.",

        "evidence": "Princeton WordNet BIBREF0 is one of the most important resources used in many different tasks across linguistics and natural language processing, however the resource is only available for English and is limited in its coverage of real world concepts. To cross the language barrier, huge efforts have been made to extend the Princeton WordNet with multilingual information in projects, such as EuroWordNet BIBREF1 , BalkaNet BIBREF2 and MultiWordNet BIBREF3 , mostly following the extend approach, where the structure of the Princeton WordNet is preserved and only the words in each synset are translated and new synsets are added for concepts. Furthermore, the Princeton WordNet has many fewer concepts than large scale encyclopedias such as Wikipedia and resources derived from it such as DBpedia BIBREF4 and BabelNet BIBREF5 . This problem is even worse for many non-English wordnets, due to the extend approach, as these resources have even fewer synsets than Princeton WordNet. Furthermore, there are still many languages for which a wordnet does not exist or is not available to all potential users due to licensing restrictions.\nTo address these deficiencies we propose two approaches. Firstly, we apply high-quality statistical machine translation (SMT) to automatically translate the WordNet entries into several different European languages. While an SMT system can only return the most frequent translation when given a term by itself, we propose a novel method to provide strong word sense disambiguation when translating wordnet entries. In addition, our method can handle fundamental complexities such as the need to translate all senses of a word including low-frequency senses, which is very challenging for current SMT approaches. For these reasons, we leverage existing translations of Princeton WordNet entries in other languages to identify contextual information for wordnet senses from a large set of generic parallel corpora. The goal is to identify sentences that share the same semantic information in respect to the synset of the Princeton WordNet entry that we want to translate. Secondly, we describe a novel system based on state-of-the-art semantic textual similarity and ontology alignment to establish a new linking between Princeton WordNet and DBpedia. This method uses a multi-feature approach to establish similarities between synsets and DBpedia entities based on analysis of the definitions using a variety of methods from simple string statistics, to methods based on explicit semantic analysis as well as deep learning methods including long short-term memory (LSTM) networks. These statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph. These are combined using a constraint-based solver that considers not only the semantic similarity of the synsets but also the overall structure of the alignment and its consistency, following the best practices in ontology alignment.\nThis work has led to the development of a large multilingual WordNet in more than 20 European languages, which we call Polylingual WordNet BIBREF6 , which is available under an open (CC-BY) license. Finally, we describe how this resource is published, firstly as linked data in the linguistic linked open data cloud, as well as published in all the formats of the Global WordNet Association Interlingual Index.\nThese statistics are created based on the Princeton WordNet synset gloss as well as the neighbouring words in the WordNet graph.",

        "question": "What model do they train for context abstraction?",
        "answer": "A pseudo language model.",
        "evidence": "Words with multiple senses commonly exist in many languages. For example, the word bank can either mean a “financial establishment” or “the land alongside or sloping down to a river or lake”, based on different contexts. Such a word is called a “polyseme”. The task to identify the meaning of a polyseme in its surrounding context is called word sense disambiguation (WSD). Word sense disambiguation is a long-standing problem in natural language processing (NLP), and has broad applications in other NLP problems such as machine translation BIBREF0 . Lexical sample task and all-word task are the two main branches of WSD problem. The former focuses on only a pre-selected set of polysemes whereas the later intends to disambiguate every polyseme in the entire text. Numerous works have been devoted in WSD task, including supervised, unsupervised, semi-supervised and knowledge based learning BIBREF1 . Our work focuses on using supervised learning to solve all-word WSD problem.\nMost supervised approaches focus on extracting features from words in the context. Early approaches mostly depend on hand-crafted features. For example, IMS by BIBREF2 uses POS tags, surrounding words and collections of local words as features. These approaches are later improved by combining with word embedding features BIBREF0 , which better represents the words' semantic information in a real-value space. However, these methods neglect the valuable positional information between the words in the sequence BIBREF3 . The bi-directional Long-Short-Term-Memory (LSTM) approach by BIBREF3 provides one way to leverage the order of words. Recently, BIBREF4 improved the performance by pre-training a LSTM language model with a large unlabelled corpus, and using this model to generate sense vectors for further WSD predictions. However, LSTM significantly increases the computational complexity during the training process.\nThe development of the so called “fixed-size ordinally forgetting encoding” (FOFE) has enabled us to consider more efficient method. As firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence. FOFE has been applied to several NLP problems in the past, such as language model BIBREF5 , named entity recognition BIBREF6 , and word embedding BIBREF7 . The promising results demonstrated by the FOFE approach in these areas inspired us to apply FOFE in solving the WSD problem. In this paper, we will first describe how FOFE is used to encode sequence of any length into a fixed-size representation. Next, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data. Lastly, we provide the experiment results of our method on several WSD data sets to justify the equivalent performance as the state-of-the-art approach.\nNext, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data.",

        "evidence": "With the massive increase in social interactions on online social networks, there has also been an increase of hateful activities that exploit such infrastructure. On Twitter, hateful tweets are those that contain abusive speech targeting individuals (cyber-bullying, a politician, a celebrity, a product) or particular groups (a country, LGBT, a religion, gender, an organization, etc.). Detecting such hateful speech is important for analyzing public sentiment of a group of users towards another group, and for discouraging associated wrongful activities. It is also useful to filter tweets before content recommendation, or learning AI chatterbots from tweets.\nThe manual way of filtering out hateful tweets is not scalable, motivating researchers to identify automated ways. In this work, we focus on the problem of classifying a tweet as racist, sexist or neither. The task is quite challenging due to the inherent complexity of the natural language constructs – different forms of hatred, different kinds of targets, different ways of representing the same meaning. Most of the earlier work revolves either around manual feature extraction BIBREF0 or use representation learning methods followed by a linear classifier BIBREF1 , BIBREF2 . However, recently deep learning methods have shown accuracy improvements across a large number of complex problems in speech, vision and text applications. To the best of our knowledge, we are the first to experiment with deep learning architectures for the hate speech detection task.\nIn this paper, we experiment with multiple classifiers such as Logistic Regression, Random Forest, SVMs, Gradient Boosted Decision Trees (GBDTs) and Deep Neural Networks(DNNs). The feature spaces for these classifiers are in turn defined by task-specific embeddings learned using three deep learning architectures: FastText, Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs). As baselines, we compare with feature spaces comprising of char n-grams BIBREF0 , TF-IDF vectors, and Bag of Words vectors (BoWV).\nMain contributions of our paper are as follows: (1) We investigate the application of deep learning methods for the task of hate speech detection.

Any other multilingual data collection would work as well, but with the selected corpus we have the advantage that we cover the same genre and roughly the same coverage for each language involved. It is also easy to divide the data into training and test sets by using Bible verse numbers, which allows us to control for semantic similarity between languages in a way that would have been difficult in a corpus that is not multi-parallel. Altogether we have 1,303 translations in 990 languages that we can use for our purposes. These were chosen so that the model alphabet size is below 1000 symbols, which was satisfied by choosing only translations in Latin, Cyrillic or Greek script.\nCertainly, there are disadvantages as well, such as the limited size (roughly 500 million tokens in total, with most languages having only one translation of the New Testament each, with roughly 200 thousand tokens), the narrow domain and the high overlap of named entities. The latter can lead to some unexpected effects when using nonsensical language vectors, as the model will then generate a sequence of random names.\nThe corpus deviates in some ways from an ideal multi-parallel corpus. Most translations are of the complete New Testament, whereas around 300 also contain the Old Testament (thus several times longer), and around ten contain only portions of the New Testament. Additionally, several languages have multiple translations, which are then concatenated. These translations may vary in age and style, but historical versions of languages (with their own ISO 639-3 code) are treated as distinct languages. During training we enforce a uniform distribution between languages when selecting training examples.\nWe base our experiments on a large collection of Bible translations crawled from the web, coming from various sources and periods of times.",

        "evidence": "Every day textual information is being added/updated on Wikipedia, as well as other social media platforms like Facebook, Twitter, etc. These platforms receive a huge amount of unverified textual data from all its users such as News Channels, Bloggers, Journalists, Field-Experts which ought to be verified before other users start consuming it. This information boom has increased the demand of information verification also known as Fact Checking. Apart from the encyclopedia and other platforms, domains like scientific publications and e-commerce also require information verification for reliability purposes. Generally, Wikipedia authors, bloggers, journalists and scientists provide references to support their claims. Providing referenced text against the claims makes the fact checking task a little easier as the verification system no longer needs to search for the relevant documents.\nWikipedia manages to verify all this new information with a number of human reviewers. Manual review processes introduce delays in publishing and is not a well scalable approach. To address this issue, researchers have launched relevant challenges, such as the Fake News Challenge (BIBREF0), Fact Extraction and VERification (FEVER) (BIBREF1) challenge along with the datasets. Moreover, Thorne and Vlachos (BIBREF2) released a survey on the current models for automated fact-checking. FEVER is the largest dataset and contains around 185k claims from the corpus of 5.4M Wikipedia articles. The claims are labeled as “SUPPORTS”, “REFUTES”, or “NOT ENOUGH INFO”, based on the evidence set.\nIn this paper, we propose an unsupervised question-answering based approach for solving the fact-checking problem. This approach is inspired from the memory-based reading comprehension task that humans perform at an early age. As we know that kids in schools, first read and learn the syllabus content so that they can answer the questions in the exam. Similarly, our model learns a language model and linguistics features in unsupervised fashion from the provided Wikipedia pages.\nTo transform the FEVER dataset into the above-mentioned task, we first generate the questions from the claims. In literature, there are majorly two types of Question Generation systems: Rule-based and Neural Question Generation (NQG) model based. Ali et al. (BIBREF3) proposed a rule-based pipeline to automate the question generation using POS (Part-of-speech) tagging and Named Entity Recognition (NER) tagging from the sentences. Recently, many NQG models have been introduced to generate questions in natural language. Serban et al. (BIBREF4) achieved better performance for question generation utilizing (passage, question, answer) triplets as training data and an encoder-decoder based architecture as their learning model.\nDu et al. (BIBREF5) introduced a sequence-to-sequence model with an attention mechanism, outperforming rule-base question generation systems. Although the models proposed in (BIBREF6; BIBREF7) are effective, they require a passage to generate the plausible questions which is not readily available in the FEVER dataset. To resolve the issues and to keep the system simple but effective, we chose to generate questions similar to a Cloze-task or masked language modeling task. Such a task makes the problem more tractable as the masked entities are already known (i.e. named entities) and tight as there is only one correct answer for a given question. Later when the answers are generated, due to the question generation process, it becomes very easy to identify the correct answers.\nWe use the BERT's (Bidirectional Encoder Representations from Transformers) (BIBREF8) masked language model, that is pre-trained on Wikipedia articles for predicting the masked entities. Currently, neither the claim verification process nor the question generation process mandates explicit reasoning. For the same reason, it is difficult to put “REFUTES” or “NOT ENOUGH INFO” labels. To resolve this issue, we classify the unsupported claims as “MANUAL_REVIEW” instead of labeling them as “NOT ENOUGH INFO” or “REFUTES”.\nIn the literature, the shared task has been tackled using pipeline-based supervised models (BIBREF9; BIBREF10; BIBREF11). To our knowledge, only BIBREF10 has provided the confusion matrix for each of the labels for their supervised system. For the same reason, we are only providing the comparison of the label accuracy on the “SUPPORTS” label in the results section.\nWe use the BERT's (Bidirectional Encoder Representations from Transformers) masked language model, that is pre-trained on Wikipedia articles for predicting the masked entities.",

For the next five years they traveled through the California coast and the midwest. Throughout their travels they documented rural poverty, in particular the exploitation of sharecroppers and migrant laborers. Taylor interviewed subjects and gathered economic data while Lange produced photographs and accompanying data. They lived and worked from Berkeley for the rest of her life.\n\nWorking for the Resettlement Administration and Farm Security Administration, Lange's images brought to public attention the plight of the poor and forgotten—particularly sharecroppers, displaced farm families, and migrant workers. Lange's work was distributed to newspapers across the country, and the poignant images became icons of the era.\n\nOne of Lange's most recognized works is Migrant Mother, published in 1936. The woman in the photograph is Florence Owens Thompson. In 1960, Lange spoke about her experience taking the photograph:\n\n\"I saw and approached the hungry and desperate mother, as if drawn by a magnet. I do not remember how I explained my presence or my camera to her, but I do remember she asked me no questions. I made five exposures, working closer and closer from the same direction. I did not ask her name or her history. She told me her age, that she was thirty-two. She said that they had been living on frozen vegetables from the surrounding fields, and birds that the children killed. She had just sold the tires from her car to buy food. There she sat in that lean-to tent with her children huddled around her, and seemed to know that my pictures might help her, and so she helped me. There was a sort of equality about it.\"\n\nLange reported the conditions at the camp to the editor of a San Francisco newspaper, showing him her photographs. The editor informed federal authorities and published an article that included some of the images. In response, the government rushed aid to the camp to prevent starvation.\n\nAccording to Thompson's son, while Lange got some details of the story wrong, the impact of the photograph came from an image that projected both the strengths and needs of migrant workers. Twenty-two of Lange's photographs produced for the FSA were included in John Steinbeck's The Harvest Gypsies when it was first published in 1936 in The San Francisco News. According to an essay by photographer Martha Rosler, Migrant Mother became the most reproduced photograph in the world.",

        "evidence": "To the best of our knowledge, we are not aware of any knowledge learning system that can learn new knowledge in the conversation process. This section thus discusses other related work.\nAmong existing KB completion approaches, BIBREF20 extended the vector space model for zero-shot KB inference. However, the model cannot handle unknown entities and can only work on fixed set of unknown relations with known embeddings. Recently, BIBREF22 proposed a method using external text corpus to perform inference on unknown entities. However, the method cannot handle unknown relations. Thus, these methods are not suitable for our open-world setting. None of the existing KB inference methods perform interactive knowledge learning like LiLi. NELL BIBREF23 continuously updates its KB using facts extracted from the Web. Our task is very different as we do not do Web fact extraction (which is also useful). We focus on user interactions in this paper. Our work is related to interactive language learning (ILL) BIBREF24 , BIBREF25 , but these are not about KB completion. The work in BIBREF26 allows a learner to ask questions in dialogue. However, this work used RL to learn about whether to ask the user or not. The “what to ask aspect\" was manually designed by modeling synthetic tasks. LiLi formulates query-specific inference strategies which embed interaction behaviors.

        "question": "What are the sources of NLP system deviation?",
        "answer": "For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.",
        "evidence": "[0]leftmargin=* [0]leftmargin=*\nAutomatic systems have had a significant and beneficial impact on all walks of human life. So much so that it is easy to overlook their potential to benefit society by promoting equity, diversity, and fairness. For example, machines do not take bribes to do their jobs, they can determine eligibility for a loan without being influenced by the color of the applicant's skin, and they can provide access to information and services without discrimination based on gender or sexual orientation. Nonetheless, as machine learning systems become more human-like in their predictions, they can also perpetuate human biases. Some learned biases may be beneficial for the downstream application (e.g., learning that humans often use some insect names, such as spider or cockroach, to refer to unpleasant situations). Other biases can be inappropriate and result in negative experiences for some groups of people. Examples include, loan eligibility and crime recidivism prediction systems that negatively assess people belonging to a certain pin/zip code (which may disproportionately impact people of a certain race) BIBREF0 and resumé sorting systems that believe that men are more qualified to be programmers than women BIBREF1 . Similarly, sentiment and emotion analysis systems can also perpetuate and accentuate inappropriate human biases, e.g., systems that consider utterances from one race or gender to be less positive simply because of their race or gender, or customer support systems that prioritize a call from an angry male over a call from the equally angry female.\nPredictions of machine learning systems have also been shown to be of higher quality when dealing with information from some groups of people as opposed to other groups of people. For example, in the area of computer vision, gender classification systems perform particularly poorly for darker skinned females BIBREF2 . Natural language processing (NLP) systems have been shown to be poor in understanding text produced by people belonging to certain races BIBREF3 , BIBREF4 . For NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.\nEven though there is some recent work highlighting such inappropriate biases (such as the work mentioned above), each such past work has largely focused on just one or two systems and resources. Further, there is no benchmark dataset for examining inappropriate biases in natural language systems. In this paper, we describe how we compiled a dataset of 8,640 English sentences carefully chosen to tease out biases towards certain races and genders. We will refer to it as the Equity Evaluation Corpus (EEC). We used the EEC as a supplementary test set in a recent shared task on predicting sentiment and emotion intensity in tweets, SemEval-2018 Task 1: Affect in Tweets BIBREF5 . In particular, we wanted to test a hypothesis that a system should equally rate the intensity of the emotion expressed by two sentences that differ only in the gender/race of a person mentioned. Note that here the term system refers to the combination of a machine learning architecture trained on a labeled dataset, and possibly using additional language resources. The bias can originate from any or several of these parts. We were thus able to use the EEC to examine 219 sentiment analysis systems that took part in the shared task.\nWe compare emotion and sentiment intensity scores that the systems predict on pairs of sentences in the EEC that differ only in one word corresponding to race or gender (e.g., `This man made me feel angry' vs. `This woman made me feel angry'). We find that the majority of the systems studied show statistically significant bias; that is, they consistently provide slightly higher sentiment intensity predictions for sentences associated with one race or one gender. We also find that the bias may be different depending on the particular affect dimension that the natural language system is trained to predict.\nDespite the work we describe here and what others have proposed in the past, it should be noted that there are no simple solutions for dealing with inappropriate human biases that percolate into machine learning systems. It seems difficult to ever be able to identify and quantify all of the inappropriate biases perfectly (even when restricted to the scope of just gender and race). Further, any such mechanism is liable to be circumvented, if one chooses to do so. Nonetheless, as developers of sentiment analysis systems, and NLP systems more broadly, we cannot absolve ourselves of the ethical implications of the systems we build. Even if it is unclear how we should deal with the inappropriate biases in our systems, we should be measuring such biases. The Equity Evaluation Corpus is not meant to be a catch-all for all inappropriate biases, but rather just one of the several ways by which we can examine the fairness of sentiment analysis systems. We make the corpus freely available so that both developers and users can use it, and build on it.\nFor NLP systems, the sources of the bias often include the training data, other corpora, lexicons, and word embeddings that the machine learning algorithm may leverage to build its prediction model.",

        "evidence": "The human evaluation of MT output in research scenarios is typically conducted by crowd workers in order to minimise costs. BIBREF13 shows that aggregated assessments of bilingual crowd workers are very similar to those of MT developers, and BIBREF14, based on experiments with data from WMT 2012, similarly conclude that with proper quality control, MT systems can be evaluated by crowd workers. BIBREF3 also use bilingual crowd workers, but the studies supporting the use of crowdsourcing for MT evaluation were performed with older MT systems, and their findings may not carry over to the evaluation of contemporary higher-quality neural machine translation (NMT) systems. In addition, the MT developers to which crowd workers were compared are usually not professional translators. We hypothesise that expert translators will provide more nuanced ratings than non-experts, and that their ratings will show a higher difference between MT outputs and human translations.\nMT has been evaluated almost exclusively at the sentence level, owing to the fact that most MT systems do not yet take context across sentence boundaries into account. However, when machine translations are compared to those of professional translators, the omission of linguistic context—e. g., by random ordering of the sentences to be evaluated—does not do justice to humans who, in contrast to most MT systems, can and do take inter-sentential context into account BIBREF15, BIBREF16. We hypothesise that an evaluation of sentences in isolation, as applied by BIBREF3, precludes raters from detecting translation errors that become apparent only when inter-sentential context is available, and that they will judge MT quality less favourably when evaluating full documents.\nThe human reference translations with which machine translations are compared within the scope of a human–machine parity assessment play an important role. BIBREF3 used all source texts of the WMT 2017 Chinese–English test set for their experiments, of which only half were originally written in Chinese; the other half were translated from English into Chinese. Since translated texts are usually simpler than their original counterparts BIBREF17, they should be easier to translate for MT systems. Moreover, different human translations of the same source text sometimes show considerable differences in quality, and a comparison with an MT system only makes sense if the human reference translations are of high quality. BIBREF3, for example, had the WMT source texts re-translated as they were not convinced of the quality of the human translations in the test set. At WMT 2018, the organisers themselves noted that the manual evaluation included several reports of ill-formed reference translations BIBREF5. We hypothesise that the quality of the human translations has a significant effect on findings of human–machine parity, which would indicate that it is necessary to ensure that human translations used to assess parity claims need to be carefully vetted for their quality.\n BIBREF3 also use bilingual crowd workers, but the studies supporting the use of crowdsourcing for MT evaluation were performed with older MT systems, and their findings may not carry over to the evaluation of contemporary higher-quality neural machine translation (NMT) systems.

The remote Arctic island of Jan Mayen and the archipelago of Svalbard also form part of Norway.[note 5] Bouvet Island, located in the Subantarctic, is a dependency of Norway; it also lays claims to the Antarctic territories of Peter I Island and Queen Maud Land. The capital and largest city in Norway is Oslo.\n\nNorway has a total area of 385,207 square kilometres (148,729 sq mi) and had a population of 5,488,984 in January 2023. The country shares a long eastern border with Sweden at a length of 1,619 km (1,006 mi). It is bordered by Finland and Russia to the northeast and the Skagerrak strait to the south, on the other side of which are Denmark and the United Kingdom. Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. The maritime influence dominates Norway's climate, with mild lowland temperatures on the sea coasts; the interior, while colder, is also significantly milder than areas elsewhere in the world on such northerly latitudes. Even during polar night in the north, temperatures above freezing are commonplace on the coastline. The maritime influence brings high rainfall and snowfall to some areas of the country.\n\nHarald V of the House of Glücksburg is the current King of Norway. Jonas Gahr Støre has been prime minister since 2021, replacing Erna Solberg. As a unitary sovereign state with a constitutional monarchy, Norway divides state power between the parliament, the cabinet and the supreme court, as determined by the 1814 constitution. The kingdom was established in 872 as a merger of many petty kingdoms and has existed continuously for 1,151 years. From 1537 to 1814, Norway was a part of the Kingdom of Denmark–Norway, and, from 1814 to 1905, it was in a personal union with the Kingdom of Sweden. Norway was neutral during the First World War, and also in World War II until April 1940 when the country was invaded and occupied by Nazi Germany until the end of the war.\n\nNorway has both administrative and political subdivisions on two levels: counties and municipalities. The Sámi people have a certain amount of self-determination and influence over traditional territories through the Sámi Parliament and the Finnmark Act. Norway maintains close ties with both the European Union and the United States. Norway is also a founding member of the United Nations, NATO, the European Free Trade Association, the Council of Europe, the Antarctic Treaty, and the Nordic Council; a member of the European Economic Area, the WTO, and the OECD; and a part of the Schengen Area.

Entity type information has shown to be useful in natural language tasks such as question answering BIBREF0 , knowledge-base population BIBREF1 , BIBREF2 , and co-reference resolution BIBREF3 . Motivated by its application to downstream tasks, recent work on entity typing has moved beyond standard coarse types towards finer-grained semantic types with richer ontologies BIBREF0 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . Rather than assuming an entity can be uniquely categorized into a single type, the task has been approached as a multi-label classification problem: e.g., in “... became a top seller ... Monopoly is played in 114 countries. ...” (fig:arch), “Monopoly” is considered both a game as well as a product.\nThe state-of-the-art approach BIBREF8 for fine-grained entity typing employs an attentive neural architecture to learn representations of the entity mention as well as its context. These representations are then combined with hand-crafted features (e.g., lexical and syntactic features), and fed into a linear classifier with a fixed threshold. While this approach outperforms previous approaches which only use sparse binary features BIBREF4 , BIBREF6 or distributed representations BIBREF9 , it has a few drawbacks: (1) the representations of left and right contexts are learnt independently, ignoring their mutual connection; (2) the attention on context is computed solely upon the context, considering no alignment to the entity; (3) document-level contexts which could be useful in classification are not exploited; and (4) hand-crafted features heavily rely on system or human annotations.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts. Further, we find that adaptive classification thresholds leads to further improvements. Experiments demonstrate that our approach, without any reliance on hand-crafted features, outperforms prior work on three benchmark datasets.\nWe found that a flat architecture with inter-sentence Transformer layers performs the best, achieving the state-of-the-art results on this task.",

        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier. When we combine the two models, we achieve state-of-the-art results over 3/4 of our datasets.\nThis paper makes the following contributions:\nAll code and data associated with this research will be released on publication.\nWe perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by Kang et al.

Hybrid systems combine hidden Markov models to model state dependencies with neural networks to predict states BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Newer approaches such as end-to-end (E2E) systems reduce the overall complexity of the final system.\nOur research builds on prior work that has explored using time-delay neural networks (TDNN), other forms of convolutional neural networks, and Connectionist Temporal Classification (CTC) loss BIBREF4 , BIBREF5 , BIBREF6 . We took inspiration from wav2letter BIBREF6 , which uses 1D-convolution layers. Liptchinsky et al. BIBREF7 improved wav2letter by increasing the model depth to 19 convolutional layers and adding Gated Linear Units (GLU) BIBREF8 , weight normalization BIBREF9 and dropout.\nBy building a deeper and larger capacity network, we aim to demonstrate that we can match or outperform non end-to-end models on the LibriSpeech and 2000hr Fisher+Switchboard tasks. Like wav2letter, our architecture, Jasper, uses a stack of 1D-convolution layers, but with ReLU and batch normalization BIBREF10 . We find that ReLU and batch normalization outperform other activation and normalization schemes that we tested for convolutional ASR. As a result, Jasper's architecture contains only 1D convolution, batch normalization, ReLU, and dropout layers – operators highly optimized for training and inference on GPUs.\nIt is possible to increase the capacity of the Jasper model by stacking these operations. Our largest version uses 54 convolutional layers (333M parameters), while our small model uses 34 (201M parameters). We use residual connections to enable this level of depth. We investigate a number of residual options and propose a new residual connection topology we call Dense Residual (DR).\nIntegrating our best acoustic model with a Transformer-XL BIBREF11 language model allows us to obtain new state-of-the-art (SOTA) results on LibriSpeech BIBREF12 test-clean of 2.95% WER and SOTA results among end-to-end models on LibriSpeech test-other.

To tackle this issue, BIBREF13 provided a subword-level solution to overcome the out-of-vocabulary (OOV) problem.\nIn this work, the systems we implement for the German-Czech language pair are built based on the previously proposed unsupervised MT systems, with some adaptations made to accommodate the morphologically rich characteristics of German and Czech BIBREF14.

We propose to train BPE embeddings for German and Czech separately and align those trained embeddings into a shared space with MUSE BIBREF0 to reduce the combinatorial explosion of word forms for both languages.

The player is tasked with managing and taking care of these duplicants as they try to survive and create a sustainable makeshift space colony. The player must monitor the duplicants' hunger, waste, and oxygen levels to keep them alive. Each game's world is procedurally generated. The world is then subdivided into various regions or \"biomes\" that contain different and often biome specific materials and critters. While initial areas have a breathable atmosphere, subsequent areas are in a vacuum or lack oxygen, requiring proper preparation by the duplicants before they explore these areas.

The game simulates the diffusion of gases and equalization of atmospheres when a new natural chamber is opened, which can cause oxygen levels to drop in existing chambers, as well as the draining of liquids by gravity.\n\nTo help establish the colony, the player directs the duplicants to perform certain tasks, such as mining for resources, growing food, crafting equipment, researching new technologies, and maintaining their own health through nourishment, rest, and hygiene. The player does not control the duplicants directly, and instead provides prioritized instructions, from which the duplicants will then follow to the best of their abilities. For example, the player can order a conduit of wire to be built; which will have the duplicants collect the materials to make the wire, clear away any materials around the conduit's path, and then construct the wire. If the duplicants cannot access a source of copper for the wire, the task will remain uncompleted as the duplicants go to complete other tasks they can do.

First we filter out low-frequency words and punctuations in WSJ, and visualize the rest words (10k) with t-SNE BIBREF42 under different embeddings. We assign each word with its most likely gold POS tags in WSJ and color them according to the gold POS tags.\nFor our Markov-structured model, we have displayed the embedding space in Figure SECREF5 , where the gold POS clusters are well-formed. Further, we present five example target words and their five nearest neighbors in terms of cosine similarity. As shown in Table TABREF53 , the skip-gram embedding captures both semantic and syntactic aspects to some degree, yet our embeddings are able to focus especially on the syntactic aspects of words, in an unsupervised fashion without using any extra morphological information.\nIn Figure FIGREF54 we depict the learned latent embeddings with the DMV-structured syntax model. Unlike the Markov structure, the DMV structure maps a large subset of singular and plural nouns to the same overlapping region. However, two clusters of singular and plural nouns are actually separated. We inspect the two clusters and the overlapping region in Figure FIGREF54 , it turns out that the nouns in the separated clusters are words that can appear as subjects and, therefore, for which verb agreement is important to model. In contrast, the nouns in the overlapping region are typically objects. This demonstrates that the latent embeddings are focusing on aspects of language that are specifically important for modeling dependency without ever having seen examples of dependency parses.

        "evidence": "With the growth of the internet in the last decades, users are faced with an increasing amount of information and have to find ways to summarize it. However, producing summaries in a multi-document setting is a challenging task; the language used to display the same information in a sentence can vary significantly, making it difficult for summarization models to capture. Thus large corpora are needed to develop efficient models. There exist two types of summarization: extractive and abstractive. Extractive summarization outputs summaries in two steps, namely via sentence ranking, where an importance score is assigned to each sentence, and via the subsequent sentence selection, where the most appropriate sentence is chosen. In abstractive summarization, summaries are generated word by word auto-regressively, using sequence-to-sequence or language models. Given the complexity of multi-document summarization and the lack of datasets, most researchers use extractive summarization and rely on hand-crafted features or additional annotated data, both needing human expertise.\nTo our knowledge, wiki2018 is the only work that has proposed a large dataset for multi-document summarization. By considering Wikipedia entries as a collection of summaries on various topics given by their title (e.g., Machine Learning, Stephen King), they create a dataset of significant size, where the lead section of an article is defined as the reference summary and input documents are a mixture of pages obtained from the article's reference section and a search engine. While this approach benefits from the large number of Wikipedia articles, in many cases, articles contain only a few references that tend to be of the desired high quality, and most input documents end up being obtained via a search engine, which results in noisy data. Moreover, at testing time no references are provided, as they have to be provided by human contributors. wiki2018 showed that in this case, generated summaries based on search engine results alone are of poor quality and cannot be used.\nIn contrast, we propose a novel domain-specific dataset containing $14\\,652$ samples, based on professional video game reviews obtained via Metacritic and gameplay sections from Wikipedia. By using Metacritic reviews in addition to Wikipedia articles, we benefit from a number of factors. First, the set of aspects used to assess a game is limited and consequently, reviews share redundancy. Second, because they are written by professional journalists, reviews tend to be in-depth and of high-quality. Additionally, when a video game is released, journalists have an incentive to write a complete review and publish it online as soon as possible to draw the attention of potential customers and increase the revenue of their website BIBREF0. Therefore, several reviews for the same product become quickly available and the first version of the corresponding Wikipedia page is usually made available shortly after. Lastly, reviews and Wikipedia pages are available in multiple languages, which opens up the possibility for multilingual multi-document summarization.\nIn contrast, we propose a novel domain-specific dataset containing $14\\,652$ samples, based on professional video game reviews obtained via Metacritic and gameplay sections from Wikipedia.",

Let v ∈ R N denote the voltages of the N neurons. The voltage v i (t) for each post-synaptic neuron i at the time t was calculated using a first-order leaky integrator equation given by\nwhere τ i is the voltage time constant, o i is the chemosensory input provided to only the sensory neurons, s c i is the chemical synaptic input, s e i is the electrical synaptic input, v rest i is the resting neuron voltage.\nWe studied two variations of the model, the current-based model and the conductance-based model, which differ in their formulations of chemical synaptic input s c i . Since neurons in the C. elegans nervous system are largely non-spiking, we model the chemical synapses as having graded release of neurotransmitter, rather than the all-or-none quantal release seen in spiking neurons. In both models, we model the amount of neurotransmitter released, W c ji g(v j (t)), in proportion to the pre-synaptic voltage v j followed by a softplus activation g(•) which sets a minimum voltage below which there is no synaptic release. We use g(•), to denote a softplus function for the rest of the paper. In our current-based model, synaptic input s c i to a post-synaptic neuron i is directly proportional pre-synaptic neurotransmitter concentration:\nwhere W c ji represents the chemical synaptic weight between pre-synaptic neuron j and post-synaptic neuron i. W c ji can be positive or negative depending on if the synaptic connection is excitatory or inhibitory. If neurons j and i are not connected, W c ji is set to zero. In the conductance-based model, we model the synaptic current entering the post-synaptic neuron with more biophysical detail as\nHere, the pre-synaptic neurotransmitter concentration W c ji g(v j (t)) is more accurately modeled as proportional to the conductance at the post-synaptic terminal. The post-synaptic current is then given by the product of the synaptic conductance and the difference between the post-synaptic voltage v i (t) and the synaptic reversal potential E ji .\nIn contrast to the current-based synapse, whose input is independent of the post-synaptic voltage v i (t), the more biophysically accurate conductance-based synapse model also has a dependence on the post-synaptic voltage. Additionally, this model decouples the sign of the synapse from the strength. The reversal potential of a synapse E ji dictates whether a synapse is excitatory or inhibitory. A large and positive E ji corresponds to an excitatory synapse causing depolarization of the postsynaptic neuron. Conversely, an inhibitory synapse will have a negative E ji causing hyperpolarization. In this model, we can now independently train the sign of a synapse and its non-negative strength W c ji , which is not easily possible with current-based synapses. In both the current-based and conductance-based models, the following equation was used to represent electrical synaptic inputs:\nwhere W e ji is restricted to be non-negative and v j − v i is the potential difference between presynaptic and postsynaptic neurons. We also restrict W e ji = W e ij because the potential differences between electrical synapses are symmetric. To directly compare the outputs of the LVM to neural activity measurements, our model must generate calcium signals from the voltage traces. We model the calcium concentration [Ca] i of each neuron i as a first-order leaky integrator, driven by voltage-gated calcium channels with the same nonlinear current-voltage (I-V) function g(v i ):\nwhere g(•) represents softplus activation, τ [Ca] is a time constant shared across all neurons. We then map calcium concentration [Ca] into the measured calcium fluorescence signals f via an affine transform with scalar α f and bias β f ,\nwith measurement noise represented by a noise amplitude σ f and a noise term f i (t) ∼ N (0, 1).These equations are simulated in discrete time using Euler integration.\nwhere g(·) represents softplus activation,",

LSTMN (Cheng, Dong, and Lapata 2016) is an extension of the LSTM model where the memory cell is replaced by a memory network which stores word representations. C-LSTM (Zhou et al. 2015) combines convolutional and recurrent neural networks. The region embeddings provided by a CNN are fed to a LSTM. SPGK (Nikolentzos et al. 2017) also models documents as word co-occurrence networks. It computes a graph kernel that compares shortest paths extracted from the word cooccurrence networks and then relies on a SVM. WMD (Kusner et al. 2015) is an application of the well- known Earth Mover's Distance to text. A k-nearest neighbor classifier is used. DiSAN (Shen et al. 2018) uses directional self-attention along with multi-dimensional attention to generate document representations. LSTM-GRNN (Tang, Qin, and Liu 2015) is a hierarchical model where sentence embeddings are obtained with a CNN and a GRU-RNN is fed the sentence representations to ob\u001ftain a document vector. HN-ATT (Yang et al. 2016) is another hierarchical model, where the same encoder architecture (a bidirectional GRU- RNN) is used for both sentences and documents. Self\u001fattention is applied at each level.",

        "question": "In what ways did the author collect the data?",
        "answer": "They extract the tweet blocks that are embedded in the news articles on the websites of CNN and NBC.",
        "evidence": "One major challenge of building a QA dataset on tweets is the sparsity of informative tweets. Many users write tweets to express their feelings or emotions about their personal lives. These tweets are generally uninformative and also very difficult to ask questions about. Given the linguistic variance of tweets, it is generally hard to directly distinguish those tweets from informative ones. In terms of this, rather than starting from Twitter API Search, we look into the archived snapshots of two major news websites (CNN, NBC), and then extract the tweet blocks that are embedded in the news articles. In order to get enough data, we first extract the URLs of all section pages (e.g. World, Politics, Money, Tech) from the snapshot of each home page and then crawl all articles with tweets from these section pages. Note that another possible way to collect informative tweets is to download the tweets that are posted by the official Twitter accounts of news media. However, these tweets are often just the summaries of news articles, which are written in formal text. As our focus is to develop a dataset for QA on informal social media text, we do not consider this approach.\nAfter we extracted tweets from archived news articles, we observed that there is still a portion of tweets that have very simple semantic structures and thus are very difficult to raise meaningful questions. An example of such tweets can be like: “Wanted to share this today - @IAmSteveHarvey\". This tweet is actually talking about an image attached to this tweet. Some other tweets with simple text structures may talk about an inserted link or even videos. To filter out these tweets that heavily rely on attached media to convey information, we utilize a state-of-the-art semantic role labeling model trained on CoNLL-2005 BIBREF15 to analyze the predicate-argument structure of the tweets collected from news articles and keep only the tweets with more than two labeled arguments. This filtering process also automatically filters out most of the short tweets. For the tweets collected from CNN, INLINEFORM0 of them were filtered via semantic role labeling. For tweets from NBC, INLINEFORM1 of the tweets were filtered.\nWe then use Amazon Mechanical Turk to collect question-answer pairs for the filtered tweets. For each Human Intelligence Task (HIT), we ask the worker to read three tweets and write two question-answer pairs for each tweet. To ensure the quality, we require the workers to be located in major English speaking countries (i.e. Canada, US, and UK) and have an acceptance rate larger than INLINEFORM0 . Since we use tweets as context, lots of important information are contained in hashtags or even emojis. Instead of only showing the text to the workers, we use javascript to directly embed the whole tweet into each HIT. This gives workers the same experience as reading tweets via web browsers and help them to better compose questions.\nTo avoid trivial questions that can be simply answered by superficial text matching methods or too challenging questions that require background knowledge. We explicitly state the following items in the HIT instructions for question writing:\nNo Yes-no questions should be asked.\nThe question should have at least five words.\nVideos, images or inserted links should not be considered.\nNo background knowledge should be required to answer the question.\nTo help the workers better follow the instructions, we also include a representative example showing both good and bad questions or answers in our instructions. Figure FIGREF14 shows the example we use to guide the workers.\nAs for the answers, since the context we consider is relatively shorter than the context of previous datasets, we do not restrict the answers to be in the tweet, otherwise, the task may potentially be simplified as a classification problem. The workers are allowed to write their answers in their own words. We just require the answers to be brief and can be directly inferred from the tweets.\nAfter we retrieve the QA pairs from all HITs, we conduct further post-filtering to filter out the pairs from workers that obviously do not follow instructions. We remove QA pairs with yes/no answers. Questions with less than five words are also filtered out. This process filtered INLINEFORM0 of the QA pairs. The dataset now includes 10,898 articles, 17,794 tweets, and 13,757 crowdsourced question-answer pairs. The collected QA pairs will be directly available to the public, and we will provide a script to download the original tweets and detailed documentation on how we build our dataset. Also note that since we keep the original news article and news titles for each tweet, our dataset can also be used to explore more challenging generation tasks. Table TABREF19 shows the statistics of our current collection, and the frequency of different types of questions is shown in Table TABREF21 . All QA pairs were written by 492 individual workers.\nFor the purposes of human performance evaluation and inter-annotator agreement checking, we launch a different set of HITs to ask workers to answer questions in the test and development set. The workers are shown with the tweet blocks as well as the questions collected in the previous step. At this step, workers are allowed to label the questions as “NA\" if they think the questions are not answerable. We find that INLINEFORM0 of the questions are labeled as unanswerable by the workers (for SQuAD, the ratio is INLINEFORM1 ). Since the answers collected at this step and previous step are written by different workers, the answers can be written in different text forms even they are semantically equal to each other. For example, one answer can be “Hillary Clinton” while the other is “@HillaryClinton”. As it is not straightforward to automatically calculate the overall agreement, we manually check the agreement on a subset of 200 random samples from the development set and ask an independent human moderator to verify the result. It turns out that INLINEFORM2 of the answers pairs are semantically equivalent, INLINEFORM3 of them are partially equivalent (one of them is incomplete) and INLINEFORM4 are totally inconsistent. The answers collected at this step are also used to measure the human performance. We have 59 individual workers participated in this process.\nIn terms of this, rather than starting from Twitter API Search, we look into the archived snapshots4 of two major news websites (CNN, NBC), and then extract the tweet blocks that are embedded in the news articles. In order to get enough data, we first extract the URLs of all section pages (e.g. World, Politics, Money, Tech) from the snapshot of each home page and then crawl all articles with tweets from these section pages.",

        "evidence": "Text simplification aims to reduce the lexical and structural complexity of a text, while still retaining the semantic meaning, which can help children, non-native speakers, and people with cognitive disabilities, to understand text better. One of the methods of automatic text simplification can be generally divided into three categories: lexical simplification (LS) BIBREF0 , BIBREF1 , rule-based BIBREF2 , and machine translation (MT) BIBREF3 , BIBREF4 . LS is mainly used to simplify text by substituting infrequent and difficult words with frequent and easier words. However, there are several challenges for the LS approach: a great number of transformation rules are required for reasonable coverage and should be applied based on the specific context; third, the syntax and semantic meaning of the sentence is hard to retain. Rule-based approaches use hand-crafted rules for lexical and syntactic simplification, for example, substituting difficult words in a predefined vocabulary. However, such approaches need a lot of human-involvement to manually define these rules, and it is impossible to give all possible simplification rules. MT-based approach has attracted great attention in the last several years, which addresses text simplification as a monolingual machine translation problem translating from 'ordinary' and 'simplified' sentences.\nIn recent years, neural Machine Translation (NMT) is a newly-proposed deep learning approach and achieves very impressive results BIBREF5 , BIBREF6 , BIBREF7 . Unlike the traditional phrased-based machine translation system which operates on small components separately, NMT system is being trained end-to-end, without the need to have external decoders, language models or phrase tables. Therefore, the existing architectures in NMT are used for text simplification BIBREF8 , BIBREF4 . However, most recent work using NMT is limited to the training data that are scarce and expensive to build. Language models trained on simplified corpora have played a central role in statistical text simplification BIBREF9 , BIBREF10 . One main reason is the amount of available simplified corpora typically far exceeds the amount of parallel data. The performance of models can be typically improved when trained on more data. Therefore, we expect simplified corpora to be especially helpful for NMT models.\nIn contrast to previous work, which uses the existing NMT models, we explore strategy to include simplified training corpora in the training process without changing the neural network architecture. We first propose to pair simplified training sentences with synthetic ordinary sentences during training, and treat this synthetic data as additional training data. We obtain synthetic ordinary sentences through back-translation, i.e. an automatic translation of the simplified sentence into the ordinary sentence BIBREF11 . Then, we mix the synthetic data into the original (simplified-ordinary) data to train NMT model. Experimental results on two publicly available datasets show that we can improve the text simplification quality of NMT models by mixing simplified sentences into the training set over NMT model only using the original training data.\nExperimental results on two publicly available datasets show that we can improve the text simplification quality of NMT models by mixing simplified sentences into the training set over NMT model only using the original training data.",

Rewards are given to the player when they collect treasures as well as when important intermediate milestones needed to further explore the world are passed. Figure FIGREF15 and Figure FIGREF1 show us a map of the world of Zork1 and the corresponding quest structure.\nThe bottleneck seen at a score of around 40 is when the player first enters the cellar on the right side of the map. The cellar is dark and you need to immediately light the lamp to see anything. Attempting to explore the cellar in the dark results in you being instantly killed by a monster known as a “grue”.\nWe make no changes from the graph update rules used by BIBREF6. Candidate interactive objects are identified by performing part-of-speech tagging on the current observation, identifying singular and proper nouns as well as adjectives, and are then filtered by checking if they can be examined using the command $examine$ $OBJ$. Only the interactive objects not found in the inventory are linked to the node corresponding to the current room and the inventory items are linked to the “you” node. The only other rule applied uses the navigational actions performed by the agent to infer the relative positions of rooms, e.g. $\\langle kitchen,down,cellar \\rangle $ when the agent performs $go$ $down$ when in the kitchen to move to the cellar.\nHyperparameters used for our agents are given below. Patience and buffer size are used for the policy chaining method as described in Section SECREF2.

        "evidence": "Task-oriented dialog systems have become ubiquitous, providing a means for billions of people to interact with computers using natural language. Moreover, the recent influx of platforms and tools such as Google's DialogFlow or Amazon's Lex for building and deploying such systems makes them even more accessible to various industries and demographics across the globe.\nTools for developing such systems start by guiding developers to collect training data for intent classification: the task of identifying which of a fixed set of actions the user wishes to take based on their query. Relatively few public datasets exist for evaluating performance on this task, and those that do exist typically cover only a very small number of intents (e.g. BIBREF0, which has 7 intents). Furthermore, such resources do not facilitate analysis of out-of-scope queries: queries that users may reasonably make, but fall outside of the scope of the system-supported intents.\nFigure FIGREF1 shows example query-response exchanges between a user and a task-driven dialog system for personal finance. In the first user-system exchange, the system correctly identifies the user's intent as an in-scope balance query. In the second and third exchanges, the user queries with out-of-scope inputs. In the second exchange, the system incorrectly identifies the query as in-scope and yields an unrelated response. In the third exchange, the system correctly classifies the user's query as out-of-scope, and yields a fallback response.\nOut-of-scope queries are inevitable for a task-oriented dialog system, as most users will not be fully cognizant of the system's capabilities, which are limited by the fixed number of intent classes. Correctly identifying out-of-scope cases is thus crucial in deployed systems—both to avoid performing the wrong action and also to identify potential future directions for development. However, this problem has seen little attention in analyses and evaluations of intent classification systems.\nThis paper fills this gap by analyzing intent classification performance with a focus on out-of-scope handling. To do so, we constructed a new dataset with 23,700 queries that are short and unstructured, in the same style made by real users of task-oriented systems. The queries cover 150 intents, plus out-of-scope queries that do not fall within any of the 150 in-scope intents.\nWe evaluate a range of benchmark classifiers and out-of-scope handling methods on our dataset. BERT BIBREF1 yields the best in-scope accuracy, scoring 96% or above even when we limit the training data or introduce class imbalance. However, all methods struggle with identifying out-of-scope queries. Even when a large number of out-of-scope examples are provided for training, there is a major performance gap, with the best system scoring 66% out-of-scope recall. Our results show that while current models work on known classes, they have difficulty on out-of-scope queries, particularly when data is not plentiful. This dataset will enable future work to address this key gap in the research and development of dialog systems. All data introduced in this paper can be found at https://github.com/clinc/oos-eval.\nWe evaluate a range of benchmark classifiers and out-of-scope handling methods on our dataset.",

        "evidence": "Titanic is a 1997 American epic romance and disaster film directed, written, produced, and co-edited by James Cameron. Incorporating both historical and fictionalized aspects, it is based on accounts of the sinking of the RMS Titanic and stars Kate Winslet and Leonardo DiCaprio as members of different social classes who fall in love aboard the ship during its ill-fated maiden voyage. The film also features Billy Zane, Kathy Bates, Frances Fisher, Gloria Stuart, Bernard Hill, Jonathan Hyde, Victor Garber, and Bill Paxton.\n\nCameron's inspiration for the film came from his fascination with shipwrecks; he felt a love story interspersed with the human loss would be essential to convey the emotional impact of the disaster. Production began on September 1, 1995, when Cameron shot footage of the actual Titanic wreck. The modern scenes on the research vessel were shot on board the Akademik Mstislav Keldysh, which Cameron had used as a base when filming the wreck. Scale models, computer-generated imagery, and a reconstruction of the Titanic built at Baja Studios were used to re-create the sinking. The film was co-financed by Paramount Pictures and 20th Century Fox; the former handled distribution in North America while the latter released the film internationally. It was the most expensive film ever made at the time, with a production budget of $200 million. Filming took place from July 1996 to March 1997.\n\nUpon its release on December 19, 1997, Titanic achieved significant critical and commercial success, and then received numerous accolades. It was praised for its visual effects, performances (particularly DiCaprio, Winslet, and Stuart), production values, Cameron's direction, musical score, cinematography, story, and emotional depth. Nominated for 14 Academy Awards, it tied All About Eve (1950) for the most Oscar nominations, and won 11, including the awards for Best Picture and Best Director, tying Ben-Hur (1959) for the most Oscars won by a single film. With an initial worldwide gross of over $1.84 billion, Titanic was the first film to reach the billion-dollar mark. It remained the highest-grossing film of all time until Cameron's next film, Avatar, surpassed it in 2010. A number of re-releases since 1997 have pushed the film's worldwide total to $2.249 billion, making it the second film to gross more than $2 billion worldwide (after Avatar).

        "answer": "Film photography had seen a long decline in popularity ever since the invention of digital cameras with their remarkable leaps in technological advances. As of today, a decent professional digital camera significantly outperforms the 35mm film cameras in terms of resolution, burst-shooting capabilities, nearly unlimited storage, and etc... In the recent years, the \"film look\" has made its comeback with lower resolution, grainy texture and unique color rendition. On top of that, half-decent retro-looking film cameras can be acquired for much less than a potent digital camera, lowering the entry barrier for those on the budget and looking for that look. An abundant pool of film stocks also adds to the fun, where each can drastically differ in low-light sensitivity, color rendition, graininess, post-processing chemistry, and of course, price. However, many major photographic film producers have either discontinued or significantly reduced the volume of their production. This, coupled with the surge in the demand, has led to skyrocketing prices on most of the still-available film stocks.

        "answer": "A combination of embeddings built on the user-to-user mention graph, the user-to-hashtag mention graph, and the text of the tweets of the troll accounts.",
        "evidence": "Internet “trolls” are users of an online community who quarrel and upset people, seeking to sow discord by posting inflammatory content. More recently, organized “troll farms” of political opinion manipulation trolls have also emerged.\nSuch farms usually consist of state-sponsored agents who control a set of pseudonymous user accounts and personas, the so-called “sockpuppets”, which disseminate misinformation and propaganda in order to sway opinions, destabilize the society, and even influence elections BIBREF0.\nThe behavior of political trolls has been analyzed in different recent circumstances, such as the 2016 US Presidential Elections and the Brexit referendum in UK BIBREF0, BIBREF1. However, this kind of analysis requires painstaking and time-consuming manual labor to sift through the data and to categorize the trolls according to their actions. Our goal in the current paper is to automate this process with the help of machine learning (ML). In particular, we focus on the case of the 2016 US Presidential Elections, for which a public dataset from Twitter is available. For this case, we consider only accounts that post content in English, and we wish to divide the trolls into some of the functional categories identified by BIBREF0: left troll, right troll, and news feed.\nWe consider two possible scenarios. The first, prototypical ML scenario is supervised learning, where we want to learn a function from users to categories {left, right, news feed}, and the ground truth labels for the troll users are available. This scenario has been considered previously in the literature by BIBREF2. Unfortunately, a solution for such a scenario is not directly applicable to a real-world use case. Suppose a new troll farm trying to sway the upcoming European or US elections has just been discovered. While the identities of the accounts might be available, the labels to learn from would not be present. Thus, any supervised machine learning approach would fall short of being a fully automated solution to our initial problem.\nA more realistic scenario assumes that labels for troll accounts are not available. In this case, we need to use some external information in order to learn a labeling function. Indeed, we leverage more persistent entities and their labels: news media. We assume a learning scenario with distant supervision where labels for news media are available. By combining these labels with a citation graph from the troll accounts to news media, we can infer the final labeling on the accounts themselves without any need for manual labeling.\nOne advantage of using distant supervision is that we can get insights about the behavior of a newly-discovered troll farm quickly and effortlessly. Differently from troll accounts in social media, which usually have a high churn rate, news media accounts in social media are quite stable. Therefore, the latter can be used as an anchor point to understand the behavior of trolls, for which data may not be available.\nWe rely on embeddings extracted from social media. In particular, we use a combination of embeddings built on the user-to-user mention graph, the user-to-hashtag mention graph, and the text of the tweets of the troll accounts. We further explore several possible approaches using label propagation for the distant supervision scenario.\nAs a result of our approach, we improve the classification accuracy by more than 5 percentage points for the supervised learning scenario. The distant supervision scenario has not previously been considered in the literature, and is one of the main contributions of the paper. We show that even by hiding the labels from the ML algorithm, we can recover 78.5% of the correct labels.\nThe contributions of this paper can be summarized as follows:\nWe predict the political role of Internet trolls (left, news feed, right) in a realistic, unsupervised scenario, where labels for the trolls are not available, and which has not been explored in the literature before.\nWe propose a novel distant supervision approach for this scenario, based on graph embeddings, BERT, and label propagation, which projects the more-commonly-available labels for news media onto the trolls who cited these media.\nWe improve over the state of the art in the traditional, fully supervised setting, where training labels are available.\nWe rely on embeddings extracted from social media. In particular, we use a combination of embeddings built on the user-to-user mention graph, the user-to-hashtag mention graph, and the text of the tweets of the troll accounts.

        "answer": "As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts.",
        "evidence": "There has been significant progress on Named Entity Recognition (NER) in recent years using models based on machine learning algorithms BIBREF0 , BIBREF1 , BIBREF2 . As with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts. In real applications, we often need to consider new types of entities in new domains where we do not have existing annotated data. For such new types of entities, however, it is very hard to find experts to annotate the data within short time limits and hiring experts is costly and non-scalable, both in terms of time and money.\nIn order to quickly obtain new training data, we can use crowdsourcing as one alternative way at lower cost in a short time. But as an exchange, crowd annotations from non-experts may be of lower quality than those from experts. It is one biggest challenge to build a powerful NER system on such a low quality annotated data. Although we can obtain high quality annotations for each input sentence by majority voting, it can be a waste of human labors to achieve such a goal, especially for some ambiguous sentences which may require a number of annotations to reach an agreement. Thus majority work directly build models on crowd annotations, trying to model the differences among annotators, for example, some of the annotators may be more trustful BIBREF3 , BIBREF4 .\nHere we focus mainly on the Chinese NER, which is more difficult than NER for other languages such as English for the lack of morphological variations such as capitalization and in particular the uncertainty in word segmentation. The Chinese NE taggers trained on news domain often perform poor in other domains. Although we can alleviate the problem by using character-level tagging to resolve the problem of poor word segmentation performances BIBREF5 , still there exists a large gap when the target domain changes, especially for the texts of social media. Thus, in order to get a good tagger for new domains and also for the conditions of new entity types, we require large amounts of labeled data. Therefore, crowdsourcing is a reasonable solution for these situations.\nIn this paper, we propose an approach to training a Chinese NER system on the crowd-annotated data. Our goal is to extract additional annotator independent features by adversarial training, alleviating the annotation noises of non-experts. The idea of adversarial training in neural networks has been used successfully in several NLP tasks, such as cross-lingual POS tagging BIBREF6 and cross-domain POS tagging BIBREF7 . They use it to reduce the negative influences of the input divergences among different domains or languages, while we use adversarial training to reduce the negative influences brought by different crowd annotators. To our best knowledge, we are the first to apply adversarial training for crowd annotation learning.\nIn the learning framework, we perform adversarial training between the basic NER and an additional worker discriminator. We have a common Bi-LSTM for representing annotator-generic information and a private Bi-LSTM for representing annotator-specific information. We build another label Bi-LSTM by the crowd-annotated NE label sequence which reflects the mind of the crowd annotators who learn entity definitions by reading the annotation guidebook. The common and private Bi-LSTMs are used for NER, while the common and label Bi-LSTMs are used as inputs for the worker discriminator. The parameters of the common Bi-LSTM are learned by adversarial training, maximizing the worker discriminator loss and meanwhile minimizing the NER loss. Thus the resulting features of the common Bi-LSTM are worker invariant and NER sensitive.\nFor evaluation, we create two Chinese NER datasets in two domains: dialog and e-commerce. We require the crowd annotators to label the types of entities, including person, song, brand, product, and so on. Identifying these entities is useful for chatbot and e-commerce platforms BIBREF8 . Then we conduct experiments on the newly created datasets to verify the effectiveness of the proposed adversarial neural network model. The results show that our system outperforms very strong baseline systems. In summary, we make the following contributions:\nAs with other Natural Language Processing (NLP) tasks, building NER systems typically requires a massive amount of labeled training data which are annotated by experts.",

        "evidence": "Named entity typing is the task of detecting the type (e.g., person, location, or organization) of a named entity in natural language text. Entity type information has shown to be useful in natural language tasks such as question answering BIBREF0 , knowledge-base population BIBREF1 , BIBREF2 , and co-reference resolution BIBREF3 . Motivated by its application to downstream tasks, recent work on entity typing has moved beyond standard coarse types towards finer-grained semantic types with richer ontologies BIBREF0 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 . Rather than assuming an entity can be uniquely categorized into a single type, the task has been approached as a multi-label classification problem: e.g., in “... became a top seller ... Monopoly is played in 114 countries. ...” (fig:arch), “Monopoly” is considered both a game as well as a product.\nThe state-of-the-art approach BIBREF8 for fine-grained entity typing employs an attentive neural architecture to learn representations of the entity mention as well as its context. These representations are then combined with hand-crafted features (e.g., lexical and syntactic features), and fed into a linear classifier with a fixed threshold. While this approach outperforms previous approaches which only use sparse binary features BIBREF4 , BIBREF6 or distributed representations BIBREF9 , it has a few drawbacks: (1) the representations of left and right contexts are learnt independently, ignoring their mutual connection; (2) the attention on context is computed solely upon the context, considering no alignment to the entity; (3) document-level contexts which could be useful in classification are not exploited; and (4) hand-crafted features heavily rely on system or human annotations.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts. Further, we find that adaptive classification thresholds leads to further improvements. Experiments demonstrate that our approach, without any reliance on hand-crafted features, outperforms prior work on three benchmark datasets.\nTo overcome these drawbacks, we propose a neural architecture (fig:arch) which learns more context-aware representations by using a better attention mechanism and taking advantage of semantic discourse information available in both the document as well as sentence-level contexts.",

It is now the primary source of information for a majority of the populace, especially for ever-changing news updates. This has also caused a shift in users' preferred sources. Previously, these preferences were static, sticking to a particular news source. Now, with the plethora of information available easily, there is no differentiation in the source it has been gathered from, with users opting to go for whatever is convenient.\nKeeping up with the times, news agencies have expanded their digital presence, increasing their reach exponentially. They generate revenue by (1) advertisements on their websites, or (2) a subscription based model for articles that might interest users. Since multiple agencies offer similar content, the user has his pick. To lure in more readers and increase the number of clicks on their content, subsequently enhancing their agency's revenue, writers have begun adopting a new technique - clickbait.\nMerriam-Webster defines clickbait as something (such as a headline) to encourage readers to click on hyperlinks based on snippets of information accompanying it, especially when those links lead to content of dubious value or interest. It is built to create, and consequently capitalise, on the Loewenstein information gap BIBREF0 by purposefully misrepresenting or promising what can be expected while reading a story on the web, be it through a headline, image or related text.\nWe propose a two-pronged approach to detect such headlines. The first component leverages distributional semantics of the title text and models its temporal and sequential properties. The article title is represented as a concatenation of its sub-word level embeddings. The sub-word representation serves as input to a bidirectional LSTM network. The contribution of a sub-word towards the clickbait nature of the headline is calculated in a differential manner since the output of the LSTM is passed into an attention layer BIBREF1 , following which it goes through a dense layer. The second component focuses on Doc2Vec embeddings of the title and article content, performing an element wise multiplication of the two. This is concatenated with the dense layer output from the previous component. The obtained output is then passed through multiple hidden layers which performs the final classification.\nPrevious work in this field that has exploited the power of embeddings has considered either word vectors, for their ability to create context-sensitive word representations, or character-level word embeddings to model the orthographic features of a word. We propose the use of sub-word level representations since it incorporates the word's morphological features. Attaching an attention mechanism to it helps us identify the surprise associated with each representation within the clickbait. One of the identifying characteristics of clickbait is that the article title differs from the text attached to it. For this reason, we define a component to capture the interaction between these attributes and augment our model.\nWe propose a two-pronged approach to detect such headlines.

Given the information overload on the web, manual monitoring for cyberbullying has become unfeasible. Automatic detection of signals of cyberbullying would enhance moderation and allow to respond quickly when necessary.\nCyberbullying research has often focused on detecting cyberbullying `attacks', hence overlooking posts written by victims and bystanders. However, these posts could just as well indicate that cyberbullying is going on. The main contribution of this paper is that it presents a system for detecting signals of cyberbullying on social media, including posts from bullies, victims and bystanders. A manually annotated cyberbullying dataset was created for two languages, which will be made available for public scientific use. Moreover, while a fair amount of research has been done on cyberbullying detection for English, we believe this is one of the first papers that focus on Dutch as well.\nA set of binary classification experiments were conducted to explore the feasibility of automatic cyberbullying detection on social media. In addition, we sought to determine which information sources contribute to this task. Two classifiers were trained on English and Dutch ASKfm data and evaluated on a holdout test of the same genre. Our experiments reveal that the current approach is a promising strategy for detecting signals of cyberbullying in social media data automatically. After feature selection and hyperparameter optimisation, the classifiers achieved an F INLINEFORM0 -score of 64.32% and 58.72% for English and Dutch, respectively. The systems hereby significantly outperformed a keyword and an (unoptimised) INLINEFORM1 -gram baseline. Analysis of the results revealed that false positives often include implicit cyberbullying or offenses through irony, the challenge of which will constitute an important area for future work.\nAnother interesting direction for future work would be the detection of fine-grained cyberbullying-related categories such as threats, curses and expressions of racism and hate. When applied in a cascaded model, the system could find severe cases of cyberbullying with high precision. This would be particularly interesting for monitoring purposes, since it would allow to prioritise signals of bullying that are in urgent need for manual inspection and follow-up.\nFinally, future work will focus on the detection of participants (or roles) typically involved in cyberbullying.

As the result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also has ground attack, electronic warfare, and signals intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.\n\nThe aircraft first flew in 1997 and was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Although the USAF had originally planned to buy a total of 750 ATFs, the program was cut to 187 operational aircraft in 2009 due to high costs, a lack of air-to-air missions at the time of production, and the development of the more affordable and versatile F-35.[N 1] The last F-22 was delivered in 2012.\n\nWhile it had a protracted development and initial operational difficulties, the F-22 has become a critical component of the USAF's tactical airpower. The fighter's combination of stealth, aerodynamic performance, and mission systems enabled a leap in air combat capabilities and set the benchmark for its generation. The F-22 is expected to serve into the 2030s and eventually be succeeded by the USAF's Next Generation Air Dominance (NGAD) manned fighter component.",

        "question": "How do they obtain a candidate's reply?",

        "evidence": "Automatic dialog/conversation systems have served humans for a long time in various fields, ranging from train routing nbcitetrain to museum guiding nbcitemuseum. In the above scenarios, the dialogs are domain-specific, and a typical approach to such in-domain systems is by human engineering, for example, using manually constructed ontologies nbciteyoungsigdial, natural language templates nbcitetemplate, and even predefined dialog states nbcitestatetracking.\nRecently, researchers have paid increasing attention to open-domain, chatbot-style human-computer conversation, because of its important commercial applications, and because it tackles the real challenges of natural language understanding and generation nbciteretrieval1,acl,aaai. For open-domain dialogs, rules and temples would probably fail as we can hardly handle the great diversity of dialog topics and natural language sentences. With the increasing number of human-human conversation utterances available on the Internet, previous studies have developed data-oriented approaches in the open domain, which can be roughly categorized into two groups: retrieval systems and generative systems.\nWhen a user issues an utterance (called a query), retrieval systems search for a most similar query in a massive database (which consists of large numbers of query-reply pairs), and respond to the user with the corresponding reply nbciteretrieval1,retrieval2. Through information retrieval, however, we cannot obtain new utterances, that is, all replies have to appear in the database. Also, the ranking of candidate replies is usually judged by surface forms (e.g., word overlaps, tf $\\cdot $ idf features) and hardly addresses the real semantics of natural languages.\nGenerative dialog systems, on the other hand, can synthesize a new sentence as the reply by language models nbciteBoWdialog,acl,aaai. Typically, a recurrent neural network (RNN) captures the query's semantics with one or a few distributed, real-valued vectors (also known as embeddings); another RNN decodes the query embeddings to a reply. Deep neural networks allow complicated interaction by multiple non-linear transformations; RNNs are further suitable for modeling time-series data (e.g., a sequence of words) especially when enhanced with long short term memory (LSTM) or gated recurrent units (GRUs). Despite these, RNN also has its own weakness when applied to dialog systems: the generated sentence tends to be short, universal, and meaningless, for example, “I don't know” nbcitenaacl or “something” nbciteaaai. This is probably because chatbot-like dialogs are highly diversified and a query may not convey sufficient information for the reply. Even though such universal utterances may be suited in certain dialog context, they make users feel boring and lose interest, and thus are not desirable in real applications.\nIn this paper, we are curious if we can combine the above two streams of approaches for open-domain conversation. To this end, we propose an ensemble of retrieval and generative dialog systems. Given a user-issued query, we first obtain a candidate reply by information retrieval from a large database. The query, along with the candidate reply, is then fed to an utterance generator based on the “bi-sequence to sequence” (biseq2seq) model nbcitemultiseq2seq. Such sequence generator takes into consideration the information contained in not only the query but also the retrieved reply; hence, it alleviates the low-substance problem and can synthesize replies that are more meaningful. After that we use the scorer in the retrieval system again for post-reranking. This step can filter out less relevant retrieved replies or meaningless generated ones. The higher ranked candidate (either retrieved or generated) is returned to the user as the reply.\nFrom the above process, we see that the retrieval and generative systems are integrated by two mechanisms: (1) The retrieved candidate is fed to the sequence generator to mitigate the “low-substance” problem; (2) The post-reranker can make better use of both the retrieved candidate and the generated utterance. In this sense, we call our overall approach an ensemble in this paper. To the best of our knowledge, we are the first to combine retrieval and generative models for open-domain conversation.\nExperimental results show that our ensemble model consistently outperforms each single component in terms of several subjective and objective metrics, and that both retrieval and generative methods contribute an important portion to the overall approach. This also verifies the rationale for building model ensembles for dialog systems.\nIn this paper, we are curious if we can combine the above two streams of approaches for open-domain conversation. To this end, we propose an ensemble of retrieval and generative dialog systems. Given a userissued query, we first obtain a candidate reply by information retrieval from a large database. The query, along with the candidate reply, is then fed to an utterance generator based on the “bi-sequence to sequence” (biseq2seq) model [30].",

        "evidence": "The guitar is a fretted musical instrument that typically has six strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A plectrum or individual finger picks may also be used to strike the strings. The sound of the guitar is projected either acoustically, by means of a resonant chamber on the instrument, or amplified by an electronic pickup and an amplifier.\n\nThe guitar is classified as a chordophone – meaning the sound is produced by a vibrating string stretched between two fixed points. Historically, a guitar was constructed from wood with its strings made of catgut. Steel guitar strings were introduced near the end of the nineteenth century in the United States, nylon strings came in the 1940s. The guitar's ancestors include the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument.\n\nThere are three main types of modern guitar: the classical guitar (Spanish guitar/nylon-string guitar), the steel-string acoustic guitar or electric guitar, and the Hawaiian guitar (played across the player's lap). Traditional acoustic guitars include the flat top guitar (typically with a large sound hole) or an arch top guitar, which is sometimes called a \"jazz guitar\". The tone of an acoustic guitar is produced by the strings' vibration, amplified by the hollow body of the guitar, which acts as a resonating chamber. The classical Spanish guitar is often played as a solo instrument using a comprehensive fingerstyle technique where each string is plucked individually by the player's fingers, as opposed to being strummed. The term \"finger-picking\" can also refer to a specific tradition of folk, blues, bluegrass, and country guitar playing in the United States.",

Rather than going through the cold boot path, Fast Startup uses a minimal hiberfile to resume the system. When the feature is enabled, selecting “Shutdown” in the Windows UI doesn’t actually shutdown the system. Instead, it closes all user applications, logs the current user out, and then creates a hiberfile. Because this hiberfile only includes the kernel, device drivers and a subset of applications, it is small and can be reloaded quickly. \n\nAlternatively, the cold boot path requires loading the kernel and drivers from disk, initializing the kernel and drivers, and launching various user mode applications. This can be especially slow on computers that use spinning hard drives.",

        "question": "What are the core features of bipolar disorder (BD)?",
        "answer": "The pole of positive/elevated mood and ongoing mood instability constitute core features of bipolar disorder (BD).",
        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nBD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression (Jones et al., 2010).",

Taskspecific supervision to other low-resource languages can not be directly transferred to other low-resource languages because the pipeline-based methods do not explicitly share the same parameter space across languages.",
        "evidence": "Learning natural language generation (NLG) models heavily relies on annotated training data. However, most available datasets are collected in a single language (typically English), which restricts deploying the applications to other languages. In this work, we aim at transferring the supervision of a monolingual NLG dataset to unseen languages, so that we can boost performance for the low-resource settings.\nVarious methods have been proposed over the years to learn universal cross-lingual word embeddings BIBREF0, BIBREF1, BIBREF2 or sentence encoders BIBREF3, BIBREF4, BIBREF5, which tries to encode multilingual texts into a single shared vector space. Despite achieving promising results on cross-lingual classification problems, cross-lingual pre-trained models purposed for NLG tasks remains relatively understudied.\nThe cross-lingual generation problem is challenging due to the following reasons. First, it requires the models to understand multilingual input texts, and generate multilingual target sequences. So both encoder and decoder should be pre-trained together. Second, the many-to-many nature of cross-lingual NLG increases language pairs with the square of the number of languages. Third, the prediction space of cross-lingual NLG is much larger than classification tasks, which makes the knowledge transfer of decoders quite critical.\nPrevious work mainly relies on machine translation (MT) systems to map texts to different languages. The first strand of research directly uses MT in a pipeline manner BIBREF6. For example, the input written in other languages is first translated to English, and fed into the NLG model that is trained by English data. Then the generated English text is translated back to the target language. Another strand of work employs MT to generate pseudo training data for other language pairs that are lack of annotations BIBREF7, BIBREF8. However, such methods have to use multiple MT systems, which renders them suffering from error propagation. Moreover, because the pipeline-based methods do not explicitly share the same parameter space across the languages, we can not directly transfer the task-specific supervision to other low-resource languages.\nIn this paper, we propose a cross-lingual pre-trained model (named as Xnlg) in order to transfer monolingual NLG supervision to other pre-trained languages by fine-tuning. Specifically, Xnlg shares the same sequence-to-sequence model across languages, and is pre-trained with both monolingual and cross-lingual objectives. The model not only learns to understand multilingual input, but also is able to generate specific languages by conditioning on the encoded semantics. Figure FIGREF2 demonstrates how to use Xnlg to perform cross-lingual transfer for downstream tasks. The proposed model enables us to fine-tune the pre-trained model on monolingual NLG training data, and then evaluate it beyond a single language, including zero-shot cross-lingual generation. Besides, we explore several fine-tuning strategies to make a compromise between cross-lingual ability and task ability. In addition, we introduce two cross-lingual NLG datasets (i.e., question generation, and abstractive summarization) for evaluation, which includes three languages, namely English, Chinese, and French. Experimental results on the NLG tasks show that Xnlg achieves competitive performance compared with the machine-translation-based pipeline model in zero-shot cross-lingual settings.\nPrevious work mainly relies on machine translation (MT) to map texts to different languages. The first strand of research directly uses MT in a pipeline manner (Wan, Li, and Xiao 2010).

Then the generated English texts are translated back to the target language. Another strand of work uses MT to generate pseudo training data for other language pairs that are lack of annotations (Shen et al. 2018; Duan et al. 2019). However, such methods have to use multiple MT systems, which renders them suffering from error propagation.

        "answer": "Meteor.",
        "evidence": "Table TABREF14 shows the results of our main experiments on the 2016 and 2018 test sets for French and German. We use Meteor BIBREF31 as the main metric, as in the WMT tasks BIBREF25 . We compare our transformer baseline to transformer models enriched with image information, as well as to the deliberation models, with or without image information.\nWe first note that our multimodal models achieve the state of the art performance for transformer networks (constrained models) on the English-German dataset, as compared to BIBREF30 . Second, our deliberation models lead to significant improvements over this baseline across test sets (average INLINEFORM0 , INLINEFORM1 ).\nTransformer-based models enriched with image information (base+sum, base+att and base+obj), on the other hand, show no major improvements with respect to the base performance. This is also the case for deliberation models with image information (del+sum, del+att, del+obj), which do not show significant improvement over the vanilla deliberation performance (del).\nHowever, as it has been shown in the WMT shared tasks on MMT BIBREF23 , BIBREF24 , BIBREF25 , automatic metrics often fail to capture nuances in translation quality, such as, the ones we expect the visual modality to help with, which – according to human perception – lead to better translations. To test this assumption in our settings, we performed human evaluation involving professional translators and native speakers of both French and German (three annotators).\nThe annotators were asked to rank randomly selected test samples according to how well they convey the meaning of the source, given the image (50 samples per language pair per annotator). For each source segment, the annotator was shown the outputs of three systems: base+att, the current MMT state-of-the-art BIBREF30 , del and del+obj. A rank could be assigned from 1 to 3, allowing ties BIBREF32 . Annotators could assign zero rank to all translations if they were judged incomprehensible. Following the common practice in WMT BIBREF32 , each system was then assigned a score which reflects the proportion of times it was judged to be better or equal other systems.\nTable TABREF19 shows the human evaluation results. They are consistent with the automatic evaluation results when it comes to the preference of humans towards the deliberation-based setups, but show a more positive outlook regarding the addition of visual information (del+obj over del) for French.\nManual inspection of translations suggests that deliberation setups tend to improve both the grammaticality and adequacy of the first pass outputs. For German, the most common modifications performed by the second-pass decoder are substitutions of adjectives and verbs (for test 2016, 15% and 12% respectively, of all the edit distance operations). Changes to adjectives are mainly grammatical, changes to verbs are contextual (e.g., changing laufen to rennen, both verbs mean run, but the second refers to running very fast). For French, 15% of all the changes are substitutions of nouns (for test 2016). These are again very contextual. For example, the French word travailleur (worker) is replaced by ouvrier (manual worker) in the contexts where tools, machinery or buildings are mentioned. For our analysis we used again spacy.\nThe information on detected objects is particularly helpful for specific adequacy issues. Figure FIGREF15 demonstrates some such cases. In the first case, the base+att model misses the translation of race car: the German word Rennen translates only the word race. del introduces the word car (Auto) into the translation. Finally, del+obj correctly translates the expression race car (Rennwagen) by exploiting the object information. For French, del translates the source part in a body of water, missing from the base+att translation. del+obj additionally translated the word paddling according to the detected object Paddle.\nWe use Meteor (Denkowski and Lavie, 2014) as the main metric, as in the WMT tasks (Barrault et al., 2018).",

Delexicalization is a common pre-processing step in dialog modeling. Specifically, delexicalization replaces the slot values with its semantic slot name(e.g. replace 18:00 with [time]). It is easier for the language modeling to process delexicalized texts, as they have a reduced vocabulary size. But these generated sentences lack the semantic information due to the delexicalization. Some previous dialog system research ignored this issue BIBREF30 or completed single delexicalized utterance BIBREF31 as generated response. We propose to perform delexicalization in dialog summary, since delexicalized utterances can simplify dialog modeling. We fill the generated templates with slots with the copy and pointing mechanism.\nWe integrate dialog domain scaffold through a multi-task framework. Dialog domain indicates different conversation task content, for example, booking hotel, restaurant and taxi in MultiWOZ dataset. Generally, the content in different domains varies so multi-domain task summarization is more difficult than single-domain. We include domain classification as the auxiliary task to incorporate the prior that different domains have different content. Feedback from the domain classification task provides domain specific information for the encoder to learn better representations. For domain classification, we feed the concatenated encoder hidden state through a binary classifier with two linear layers, producing domain probability $d$.

        "answer": "A multi-layer formulation of Twitter diffusion networks.",
        "evidence": "In recent years there has been increasing interest on the issue of disinformation spreading on online social media. Global concern over false (or \"fake\") news as a threat to modern democracies has been frequently raised–ever since 2016 US Presidential elections–in correspondence of events of political relevance, where the proliferation of manipulated and low-credibility content attempts to drive and influence people opinions BIBREF0BIBREF1BIBREF2BIBREF3.\nResearchers have highlighted several drivers for the diffusion of such malicious phenomenon, which include human factors (confirmation bias BIBREF4, naive realism BIBREF5), algorithmic biases (filter bubble effect BIBREF0), the presence of deceptive agents on social platforms (bots and trolls BIBREF6) and, lastly, the formation of echo chambers BIBREF7 where people polarize their opinions as they are insulated from contrary perspectives.\nThe problem of automatically detecting online disinformation news has been typically formulated as a binary classification task (i.e. credible vs non-credible articles), and tackled with a variety of different techniques, based on traditional machine learning and/or deep learning, which mainly differ in the dataset and the features they employ to perform the classification. We may distinguish three approaches: those built on content-based features, those based on features extracted from the social context, and those which combine both aspects. A few main challenges hinder the task, namely the impossibility to manually verify all news items, the lack of gold-standard datasets and the adversarial setting in which malicious content is created BIBREF3BIBREF6.\nIn this work we follow the direction pointed out in a few recent contributions on the diffusion of disinformation compared to traditional and objective information. These have shown that false news spread faster and deeper than true news BIBREF8, and that social bots and echo chambers play an important role in the diffusion of malicious content BIBREF6, BIBREF7. Therefore we focus on the analysis of spreading patterns which naturally arise on social platforms as a consequence of multiple interactions between users, due to the increasing trend in online sharing of news BIBREF0.\nA deep learning framework for detection of fake news cascades is provided in BIBREF9, where the authors refer to BIBREF8 in order to collect Twitter cascades pertaining to verified false and true rumors. They employ geometric deep learning, a novel paradigm for graph-based structures, to classify cascades based on four categories of features, such as user profile, user activity, network and spreading, and content. They also observe that a few hours of propagation are sufficient to distinguish false news from true news with high accuracy. Diffusion cascades on Weibo and Twitter are analyzed in BIBREF10, where authors focus on highlighting different topological properties, such as the number of hops from the source or the heterogeneity of the network, to show that fake news shape diffusion networks which are highly different from credible news, even at early stages of propagation.\nIn this work, we consider the results of BIBREF11 as our baseline. The authors use off-the-shelf machine learning classifiers to accurately classify news articles leveraging Twitter diffusion networks. To this aim, they consider a set of basic features which can be qualitatively interpreted w.r.t to the social behavior of users sharing credible vs non-credible information. Their methodology is overall in accordance with BIBREF12, where authors successfully detect Twitter astroturfing content, i.e. political campaigns disguised as spontaneous grassroots, with a machine learning framework based on network features.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks. For each article we disentangle different social interactions on Twitter, namely tweets, retweets, mentions, replies and quotes, to accordingly build a diffusion network composed of multiple layers (on for each type of interaction), and we compute structural features separately for each layer. We pick a set of global network properties from the network science toolbox which can be qualitatively explained in terms of social dimensions and allow us to encode different networks with a tuple of features. These include traditional indicators, e.g. network density, number of strong/weak connected components and diameter, and more elaborated ones such as main K-core number BIBREF13 and structural virality BIBREF14. Our main research question is whether the use of a multi-layer, disentangled network yields a significant advance in terms of classification accuracy over a conventional single-layer diffusion network. Additionally, we are interested in understanding which of the above features, and in which layer, are most effective in the classification task.\nWe perform classification experiments with an off-the-shelf Logistic Regression model on two different datasets of mainstream and disinformation news shared on Twitter respectively in the United States and in Italy during 2019. In the former case we also account for political biases inherent to different news sources, referring to the procedure proposed in BIBREF2 to label different outlets. Overall we show that we are able to classify credible vs non-credible diffusion networks (and consequently news articles) with high accuracy (AUROC up to 94%), even when accounting for the political bias of sources (and training only on left-biased or right-biased articles). We observe that the layer of mentions alone conveys useful information for the classification, denoting a different usage of this functionality when sharing news belonging to the two news domains. We also show that most discriminative features, which are relative to the breadth and depth of largest cascades in different layers, are the same across the two countries.\nThe outline of this paper is the following: we first formulate the problem and describe data collection, network representation and structural properties employed for the classification; then we provide experimental results–classification performances, layer and feature importance analyses and a temporal classification evaluation–and finally we draw conclusions and future directions.\nIn this paper, we propose a classification framework based on a multi-layer formulation of Twitter diffusion networks.",

It is unsupervised, local, and requires no error or other feedback currents from upper layers, thus solving hardware-inefficiencies and bio-implausibilities of backpropagation such as weight-transport and update-locking. Surprisingly, it surpasses backpropagation even in accuracy, when training time and network size are limited. In a demonstration that goes beyond the common greedy-training approach to such networks, we achieved update-unlocked operation in practice, by updating the first layer before the input's full processing by the next layer. It is intriguing that, through its biological plausibility, emerge properties commonly associated with biological intelligence, such as speed of learning, and robustness to noise and adversarial attacks. Significant robustness emerges without specialized defences. Furthermore, SoftHebb tends to not merely be robust to attacks, but actually deflect them as specialized SOTA defences aim to do.\nHere, we explored SoftHebb's applicability on several datasets. We measured its accuracy on MNIST, Fashion-MNIST, and CIFAR-10 in preliminary results, and we reported a functional convolutional SoftHebb network that improves accuracy on the significantly harder dataset of CIFAR-10. The convolutional implementation could become the foundation for deeper networks and complex problems. Ultimately, this could provide insights into the role of WTA microcircuits in larger networks in cortex with localized receptive fields, similar to area V1 of cortex. All in all, the algorithm has several properties that are individually interesting and novel, and worth future extension. Combined, however, SoftHebb's properties shown in this work may already enable certain small-scale but previously-impossible applications. For example, fast, on-line, unsupervised learning of simple tasks by edge sensing devices, operating in noisy conditions, with a small battery and only local processing, requires those algorithmic properties that we demonstrated here.\nREPRODUCIBILITY STATEMENT Some of our main contributions are theoretical and their proof is fully reproducible by following the rigorous derivations in the main text and in the appendices. Our experimental results are based on standard machine-learning techniques, while we also describe the hyperparameters and experimental protocols. Moreover, we provide Python code with specific instructions to reproduce the main experiments. calculate weight change ∆w\nThe cosine similarity between the input vector and each centroid's parameters underpins the model (Eq. 4). This similarity is precisely computed by a linear neuron that receives normalized inputs x * := x ||x|| , and that normalizes its vector of synaptic weights: w * k := w ||w|| . Specifically, the neuron's summed weighted input u k = w * k • x * then determines the cosine similarity of an input sample to the weight vector, thus computing the likelihood function of each component of the input mixture (Eq. 2). It should be noted that even though u k depends on the weights of all input synapses, the weight values of other synapses do not need to be known to each updated synapse. Therefore, in the SoftHebb plasticity rule that we will present (Eq. 8), the term u k is a local, postsynaptic variable that does not undermine the locality of the plasticity. The bias term of each neuron can store the parameter w 0k of the prior Q(C k ; w 0k ). Based on these, it can also be shown that a set of K such neurons can actually compute the Bayesian posterior, if the neurons are connected in a configuration that implements softmax. Softmax has a biologically-plausible implementation through lateral inhibition (divisive normalization) between neurons. Specifically, based on the model of Definition 2.2, the posterior probability is\nBut in the neural description, u k + w 0k is the activation of the k-th linear neuron. That is, Eq. 7 shows that the result of Bayesian inference of the hidden cause from the input Q(C k |x) is found by a softmax operation on the linear neural activations. In this equivalence, we will be using y k := Q(C k |x; w) to symbolize the softmax output of the k-th neuron, i.e. the output after the WTA operation, interchangeably with Q(C k |x). It can be seen in Eq. 7 that the probabilistic model has one more, alternative, but equivalent neural interpretation. Specifically, Q(C k |x) can be described as the output of a neuron with exponential activation function (numerator in Eq. 7) that is normalized by its layer's total output (denominator). This is equally accurate, and more directly analogous to the biological description. This shows that the exponential activation of each individual neuron k directly equals the k-th exponential component distribution of the generative mixture model (Eq. 4). Therefore, the softmax-configured linear neurons, or equivalently, the normalized exponential neurons, fully implement the generative model of Definition 2.2, and also infer the Bayesian posterior probability given an input and the model parameters. However, the problem of calculating the model's parameters from data samples is a difficult one, if the input distribution's parameters are unknown. In the next sections we will show that this neural network can find these optimal parameters through Bayesian inference, in an unsupervised and on-line manner, based on only local Hebbian plasticity.\nState-of-the-art (SOTA) artificial neural networks (ANNs) achieve impressive results in a variety of machine intelligence tasks. However, they largely rely on mechanisms that diverge from the original inspiration from biological neural networks. As a result, only a small part of this prolific field also contributes to computational neuroscience. In fact, this biological implausibility is also an important issue for machine intelligence. For their impressive performance, ANNs trade off other desired properties, which are present in biological systems. For example, ANN training often demands very large and labelled datasets. When labels are unavailable, self-supervised learning schemes exist, where supervisory error signals generated by the network itself are exploited and backpropagated from the output towards the input to update the network's parameters. However, this global propagation of signals in deep networks introduces another limitation. Namely, it prevents the implementation of efficient distributed computing hardware that would be based on only local signals from neighbouring physical nodes in the network, and is in contrast to local synaptic plasticity rules that partly govern biological learning. Several pieces of work have been addressing parts of the biological implausibility and hardware-inefficiency of backpropagation in ANNs. such as the need for exactly symmetric forward and backward weights or the waiting time caused by the network's forward-backward pass between two training updates in a layer (weight transport and update-locking problems). Recently, an approximation to backpropagation that is mostly Hebbian, i.e. relies on mostly pre-and post-synaptic activity of each synapse, has been achieved by reducing the global error requirements to 1-bit information. Two schemes that further localize the signal that is required for a weight update are Equilibrium Propagation and Predictive Coding. Both methods approximate backpropagation through Hebbian-like learning, by delegating the global aspect of the computation, from a global error signal, to a global convergence of the network state to an equilibrium. This equilibrium is reached through several iterative steps of feed-forward and feed-back communication throughout the network, before the ultimate weight update by one training example. The biological plausibility and hardware-efficiency of this added iterative process of signal propagation are open questions that begin to be addressed.\nMoreover, learning through backpropagation, and presumably also its approximations, has another indication of biological implausibility, which also significantly limits ANN applicability. Namely, it produces networks that are confused by small adversarial perturbations of the input, which are imperceptible by humans. It has recently been proposed that a defence strategy of \"deflection\" of adversarial attacks may be the ultimate solution to that problem. Through this strategy, to cause confusion in the network's inferred class, the adversary is forced to generate such a changed input that really belongs to the distribution of a different input class. Intuitively, but also strictly by definition, this deflection is achieved if a human assigns to the perturbed input the same label that the network does. Deflection of adversarial attacks in ANNs has been demonstrated by an elaborate scheme that is based on detecting the attacks. However, the human ability to deflect adversarial perturbations likely does not rely on detecting them, but rather on effectively ignoring them, making the deflecting type of robustness an emergent property of biological computation rather than a defence mechanism. The biological principles that underlie this property of robustness are unclear, but it might emerge from the distinct algorithms that govern learning in the brain.\nTherefore, what is missing is a biologically plausible model that can learn from fewer data-points, without labels, through local plasticity, and without feedback from distant layers. This model could then be tested for emergent adversarial robustness. A good candidate category of biological networks and learning algorithms is that of competitive learning. Neurons that compete for their activation through lateral inhibition are a common connectivity pattern in the superficial layers of the cerebral cortex). This pattern is described as winner-take-all (WTA), because competition suppresses activity of weakly activated neurons, and emphasizes strong ones. Combined with Hebbian-like plasticity rules, WTA connectivity gives rise to competitivelearning algorithms. These networks and learning schemes have been long studied (Von der and a large literature based on simulations and analyses describes their functional properties. A WTA neuronal layer, depending on its specifics, can restore missing input signals, perform decision making i.e. winner selection, and generate oscillations such as those that underlie brain rhythms. Perhaps more importantly, its neurons can learn to become selective to different input patterns, such as orientation of visual bars in models of the primary visual cortex (Von der, MNIST handwritten digits, CIFAR10 objects, spatiotemporal spiking patterns, and can adapt dynamically to model changing objects. The WTA model is indeed biologically plausible, Hebbian plasticity is local, and learning is input-driven, relying on only feed-forward communication of neurons -properties that seem to address several of the limitations of ANNs. However, the model's applicability is limited to simple tasks. That is partly because the related theoretical literature remains surprisingly unsettled, despite its long history, and the strong and productive community interest. described a very related theory but for a model that is largely incompatible with ANNs and thus less practical. It uses spiking and stochastic neurons, input has to be discretized, and each input feature must be encoded through multiple binary neurons. Moreover, it was only proven for neurons with an exponential activation function. It remains therefore unclear which specific plasticity rule and structure could optimize an ANN WTA for Bayesian inference. It is also unclear how to minimize a common loss function such as cross-entropy despite unsupervised learning, and how a WTA could represent varying families of probability distributions. In summary, on the theoretical side, an algorithm that is simultaneously normative, based on WTA networks and Hebbian unsupervised plasticity, performs Bayesian inference, and, importantly, is composed of conventional, i.e. non-spiking, ANN elements and is rigorously linked to modern ANN tools such as cross-entropy loss, would be an important advance but has been missing. On the practical side, evidence that Hebbian WTA networks could be useful for presently pertinent issues of modern ANNs such as adversarial robustness, generation of synthetic images, or faster learning, has remained limited. Here we aim to fill these gaps. Recently, when WTA networks were studied in a theoretical framework compatible with conventional machine learning (ML), but in the context of short-term as opposed to long-term Hebbian plasticity, it resulted in surprising practical advantages over supervised ANNs. A similar theoretical approach could also reveal unknown advantages of long-term Hebbian plasticity in WTA networks. In addition, it could provide insights into how a WTA microcircuit could participate in larger-scale computation by deeper cortical or artificial networks.\nHere we construct \"SoftHebb\", a biologically plausible WTA model that is based on standard ratebased neurons as in ANNs, can accommodate various activation functions, and learns without labels, using local plasticity and only feed-forward communication, i.e. the properties we seek in an ANN. Importantly, it is equipped with a simple normalization of the layer's activations, and an optional temperature-scaling mechanism, producing a soft WTA instead of selecting a single \"hard\" winner neuron. This allows us to prove formally that a SoftHebb layer is a generative mixture model that objectively minimizes its Kullback-Leibler (KL) divergence from the input distribution through Bayesian inference, thus providing a new formal ML-theoretic perspective of these networks. We complement our main results, which are theoretical, with experiments that are small-scale but produce intriguing results. As a generative model, SoftHebb has a broader scope than classification, but we test it on image classification tasks. Surprisingly, in addition to overcoming several inefficiencies of backpropagation, the unsupervised WTA model also outperforms a supervised two-layer perceptron in several aspects: learning speed and accuracy in the first presentation of the training dataset, robustness to noisy data and to one of the strongest white-box adversarial attacks, i.e. projected gradient descent (PGD), and without any explicit defence. Interestingly, the SoftHebb model also exhibits inherent properties of deflection of the adversarial attacks, and generates object interpolations.\nIt is unsupervised, local, and requires no error or other feedback currents from upper layers, thus solving hardware-inefficiencies and bio-implausibilities of backpropagation such as weight-transport and update-locking.****Therefore, in the SoftHebb plasticity rule that we will present (Eq. 8), the term  uk is a local, postsynaptic variable that does not undermine the locality of the plasticity.****Some of our main contributions are theoretical and their proof is fully reproducible by following the rigorous derivations in the main text and in the appendices.****Surprisingly, in addition to overcoming several inefficiencies of backpropagation, the unsupervised WTA model also outperforms a supervised two-layer perceptron in several aspects: learning speed and accuracy in the first presentation of the training dataset, robustness to noisy data and to one of the strongest white-box adversarial attacks, i.e. projected gradient descent (PGD) (Madry et al., 2017), and without any explicit defence.

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously. In addition, we demonstrate that applying a typical LSTM to preprocess the leaf nodes of a tree-LSTM greatly improves the performance of the tree models. Moreover, we propose a clustered tag set to replace the existing tags on the assumption that the original syntactic tags are too fined-grained to be useful in neural models.\nIn short, our contributions in this work are as follows:\n• We propose a new linguistically-motivated neural model which generates high-quality sentence representations by considering all the information extracted from constituency parse trees.  • In addition, we demonstrate the superiority of the proposed models achieving new state-of-the-art performance within the similar model class on 4 out of 5 sentence classification benchmarks, as well as showing competitive results compared to other types of neural models.  • We empirically show that another key point to the success of tree-structured models is to contextualize input word embeddings so that the corresponding input for each word in a sentence can better reflect the meaning of the whole sentence",

        "evidence": "Learning the distributed representation for long spans of text from its constituents has been a key step for various natural language processing (NLP) tasks, such as text classification BIBREF0 , BIBREF1 , semantic matching BIBREF2 , BIBREF3 , and machine translation BIBREF4 . Existing deep learning approaches take a compositional function with different forms to compose word vectors recursively until obtaining a sentential representation. Typically, these compositional functions involve recurrent neural networks BIBREF5 , BIBREF6 , convolutional neural networks BIBREF7 , BIBREF8 , and tree-structured neural networks BIBREF9 , BIBREF10 .\nAmong these methods, tree-structured neural networks (Tree-NNs) show theirs superior performance in many NLP tasks BIBREF11 , BIBREF12 . Following the syntactic tree structure, Tree-NNs assign a fixed-length vector to each word at the leaves of the tree, and combine word and phrase pairs recursively to create intermediate node vectors, eventually obtaining one final vector to represent the whole sentence.\nHowever, these models have a major limitation in their inability to fully capture the richness of compositionality BIBREF13 . The same parameters are used for all kinds of semantic compositions, even though the compositions have different characteristics in nature. For example, the composition of the adjective and the noun differs significantly from the composition of the verb and the noun. Moreover, many semantic phenomena, such as semantic idiomaticity or transparency, call for more powerful compositional mechanisms BIBREF14 . Therefore, Tree-NNs suffer from the underfitting problem.\nTo alleviate this problem, some researchers propose to use multiple compositional functions, which are arranged beforehand according to some partition criterion BIBREF11 , BIBREF13 , BIBREF15 . Intuitively, using different parameters for different types of compositions has the potential to greatly reduce underfitting. BIBREF13 [ BIBREF13 ] defined different compositional functions in terms of syntactic categories, and a suitable compositional function is selected based on the syntactic categories. BIBREF15 [ BIBREF15 ] introduced multiple compositional functions and during compositional phase, a proper one is selected based on the input information. Although these models accomplished their mission to a certain extent, they still suffer from the following three challenges. First, the predefined compositional functions cannot cover all the compositional rules; Second, they require more learnable parameters, suffering from the problem of overfitting; Third, it is difficult to determine a universal criterion for semantic composition based solely on syntactic categories.\nIn this paper, we propose dynamic compositional neural networks over tree structure, in which a meta network is used to generate the context-specific parameters of a dynamic compositional network. Specifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) BIBREF11 and tree-structure long short-term memory neural network (Tree-LSTM) BIBREF9 . Our work is inspired by recent work on dynamic parameter prediction BIBREF16 , BIBREF17 , BIBREF18 . The meta network is used to extract the shared meta-knowledge across different compositional rules and to dynamically generate the context-specific compositional function. Thus, the compositional function of our models varies with positions, contexts and samples. The dynamic compositional network then applies those context-specific parameters to the current input information. Both meta and dynamic networks are differentiable such that the overall networks can be trained in an end-to-end fashion. Additional, to reduce the complexity of the whole networks, we define the dynamic weight matrix in a manner simulating low-rank matrix decomposition.\nWe evaluate our models on two typical tasks: text classification and text semantic matching. The results show that our models are more expressive due to their learning to learn nature, yet without increasing the number of model's parameters. Moreover, we find certain composition operations can be learned implicitly by meta TreeNN, such as the composition of noun phrases and verb phrases.\nThe contributions of the paper can be summed up as follows.\nSpecifically, we construct our models based on two kinds of tree-structured neural networks: recursive neural network (Tree-RecNN) and tree-structure long short-term memory neural network (Tree-LSTM) .",

        "evidence": "\nWe consider two datasets, representing related but slightly different forecasting tasks. The first dataset is an expanded version of the annotated Wikipedia conversations dataset from BIBREF9. This dataset uses carefully-controlled crowdsourced labels, strictly filtered to ensure the conversations are civil up to the moment of a personal attack. This is a useful property for the purposes of model analysis, and hence we focus on this as our primary dataset. However, we are conscious of the possibility that these strict labels may not fully capture the kind of behavior that moderators care about in practice. We therefore introduce a secondary dataset, constructed from the subreddit ChangeMyView (CMV) that does not use post-hoc annotations. Instead, the prediction task is to forecast whether the conversation will be subject to moderator action in the future.\nWikipedia data. BIBREF9's `Conversations Gone Awry' dataset consists of 1,270 conversations that took place between Wikipedia editors on publicly accessible talk pages. The conversations are sourced from the WikiConv dataset BIBREF59 and labeled by crowdworkers as either containing a personal attack from within (i.e., hostile behavior by one user in the conversation directed towards another) or remaining civil throughout.\nA series of controls are implemented to prevent models from picking up on trivial correlations. To prevent models from capturing topic-specific information (e.g., political conversations are more likely to derail), each attack-containing conversation is paired with a clean conversation from the same talk page, where the talk page serves as a proxy for topic. To force models to actually capture conversational dynamics rather than detecting already-existing toxicity, human annotations are used to ensure that all comments preceding a personal attack are civil.\nTo the ends of more effective model training, we elected to expand the `Conversations Gone Awry' dataset, using the original annotation procedure. Since we found that the original data skewed towards shorter conversations, we focused this crowdsourcing run on longer conversations: ones with 4 or more comments preceding the attack. Through this additional crowdsourcing, we expand the dataset to 4,188 conversations, which we are publicly releasing as part of the Cornell Conversational Analysis Toolkit (ConvoKit).\nWe perform an 80-20-20 train/dev/test split, ensuring that paired conversations end up in the same split in order to preserve the topic control. Finally, we randomly sample another 1 million conversations from WikiConv to use for the unsupervised pre-training of the generative component.\nReddit CMV data. The CMV dataset is constructed from conversations collected via the Reddit API. In contrast to the Wikipedia-based dataset, we explicitly avoid the use of post-hoc annotation. Instead, we use as our label whether a conversation eventually had a comment removed by a moderator for violation of Rule 2: “Don't be rude or hostile to other users”.\nThough the lack of post-hoc annotation limits the degree to which we can impose controls on the data (e.g., some conversations may contain toxic comments not flagged by the moderators) we do reproduce as many of the Wikipedia data's controls as we can. Namely, we replicate the topic control pairing by choosing pairs of positive and negative examples that belong to the same top-level post, following BIBREF12; and enforce that the removed comment was made by a user who was previously involved in the conversation. This process results in 6,842 conversations, to which we again apply a pair-preserving 80-20-20 split. Finally, we gather over 600,000 conversations that do not include any removed comment, for unsupervised pre-training.\nWe consider two datasets, representing related but slightly different forecasting tasks.

Initially a Federalist like his father, he won election to the presidency as a member of the Democratic-Republican Party, and in the mid-1830s became affiliated with the Whig Party.\n\nBorn in Braintree, Massachusetts, Adams spent much of his youth in Europe, where his father served as a diplomat. After returning to the United States, Adams established a successful legal practice in Boston. In 1794, President George Washington appointed Adams as the U.S. ambassador to the Netherlands, and Adams would serve in high-ranking diplomatic posts until 1801, when Thomas Jefferson took office as president. Federalist leaders in Massachusetts arranged for Adams's election to the United States Senate in 1802, but Adams broke with the Federalist Party over foreign policy and was denied re-election. In 1809, President James Madison, a member of the Democratic-Republican Party, appointed Adams as the U.S. ambassador to Russia. Multilingual, Adams held diplomatic posts for the duration of Madison's presidency, and he served as part of the American delegation that negotiated an end to the War of 1812. In 1817, President James Monroe selected Adams as his Secretary of State. In that role, Adams negotiated the Adams–Onís Treaty, which provided for the American acquisition of Florida. He also helped formulate the Monroe Doctrine, which became a key tenet of U.S. foreign policy. In 1818, Adams was elected a member of the American Philosophical Society in Philadelphia.\n\nAdams, Andrew Jackson, William H. Crawford, and Henry Clay—all members of the Democratic-Republican Party—competed in the 1824 presidential election. Because no candidate won a majority of electoral votes, the House of Representatives held a contingent election, which Adams won with the support of Speaker of the House Clay, whom Adams would go on to controversially appoint as his Secretary of State. As president, Adams called for an ambitious agenda that included federally funded infrastructure projects, the establishment of a national university, and engagement with the countries of Latin America, but Congress refused to pass many of his initiatives. During Adams's presidency, the Democratic-Republican Party split into two major camps: the National Republican Party, which supported President Adams, and Andrew Jackson's Democratic Party. The Democrats proved to be more effective political organizers than Adams and his National Republican supporters, and Jackson soundly defeated Adams in the 1828 presidential election, making Adams the second president to fail to win re-election (his father being the first).\n\nRather than retiring from public service, Adams won election to the House of Representatives, where he would serve from 1831 until his death in 1848. He remains the only former president to be elected to the chamber. After narrowly losing his bids for Governor of Massachusetts and Senate re-election, Adams joined the Anti-Masonic Party in the early 1830s before joining the Whig Party, which united those opposed to President Jackson. During his time in Congress, Adams became increasingly critical of slavery and of the Southern leaders whom he believed controlled the Democratic Party. He was particularly opposed to the annexation of Texas and the Mexican–American War, which he saw as a war to extend slavery and its political grip on Congress. He also led the repeal of the \"gag rule\", which had prevented the House of Representatives from debating petitions to abolish slavery. Historians concur that Adams was one of the greatest diplomats and secretaries of state in American history; they typically rank him as an average president, as he had an ambitious agenda but could not get it passed by Congress. By contrast, historians also view Adams in a more positive light during his post-presidency because of his vehement stance against slavery, as well as his fight for the rights of women and Native Americans.",

The statistical analysis shows a significant improvement over Rasa $[Z=-2.803, p = .005]$, Dialogflow $[Z=-2.803, p = .005]$, LUIS $[Z=-2.803, p = .005]$ and Watson $[Z=-2.803, p = .005]$.\nFLOAT SELECTED: Table 4: Comparison of HERMIT with the results in (Liu et al., 2019) by combining Intent and Entity.\nIn this section we report the experiments performed on the ROMULUS dataset (Table TABREF27). Together with the evaluation metrics used in BIBREF7, we report the span F1, computed using the CoNLL-2000 shared task evaluation script, and the Exact Match (EM) accuracy of the entire sequence of labels. It is worth noticing that the EM Combined score is computed as the conjunction of the three individual predictions – e.g., a match is when all the three sequences are correct.\nResults in terms of EM reflect the complexity of the different tasks, motivating their position within the hierarchy. Specifically, dialogue act identification is the easiest task ($89.31\\%$) with respect to frame ($82.60\\%$) and frame element ($79.73\\%$), due to the shallow semantics it aims to catch. However, when looking at the span F1, its score ($89.42\\%$) is lower than the frame element identification task ($92.26\\%$). What happens is that even though the label set is smaller, dialogue act spans are supposed to be longer than frame element ones, sometimes covering the whole sentence. Frame elements, instead, are often one or two tokens long, that contribute in increasing span based metrics. Frame identification is the most complex task for several reasons. First, lots of frame spans are interlaced or even nested; this contributes to increasing the network entropy. Second, while the dialogue act label is highly related to syntactic structures, frame identification is often subject to the inherent ambiguity of language (e.g., get can evoke both Commerce_buy and Arriving). We also report the metrics in BIBREF7 for consistency. For dialogue act and frame tasks, scores provide just the extent to which the network is able to detect those labels. In fact, the metrics do not consider any span information, essential to solve and evaluate our tasks.

        "evidence": "",
        "answer": "As we age, our bodies undergo various changes. One of the most significant changes is the decrease in muscle mass and strength. This loss of muscle mass is known as sarcopenia and can start as early as age 30, with a more rapid decline after age 60. This may lead many people to believe that gaining muscle after 35 is impossible, but is that really the case?\nYes, it's possible to build muscle after 35\n\nThe short answer is yes, it is possible to build muscle after 35. In fact, strength training can be just as effective for older adults as it is for younger ones. It's never too late to start working on your fitness goals and building the body you want.\n\nThe benefits of building muscle after 35\n\nAs we age, building muscle becomes increasingly important for several reasons. First and foremost, it can help us maintain our independence and mobility as we age. Strong muscles can help us with everyday activities like carrying groceries or getting up from a chair. Building muscle can also help prevent injuries and falls, which can be more dangerous as we get older.\n\nAdditionally, building muscle can help improve our overall health. Muscle is more metabolically active than fat, which means it burns more calories at rest. This can help us maintain a healthy weight and lower our risk of developing chronic diseases like type 2 diabetes, heart disease, and certain types of cancer.\n\nHow to build muscle after 35\n\nSo, how exactly do you go about building muscle after 35? The key is to focus on strength training exercises that target multiple muscle groups. Compound exercises like squats, deadlifts, and bench presses are great for building overall strength and muscle mass.\nIt's also important to gradually increase the weight and intensity of your workouts over time. This will help you continue to make progress and avoid plateauing. Additionally, be sure to give your muscles time to rest and recover between workouts.\n\nFinally, proper nutrition is crucial for building muscle at any age. Make sure you're getting enough protein, as this is essential for muscle growth and repair. Aim for at least 1 gram of protein per pound of body weight per day.\n\nBuilding muscle after 35 is definitely possible, and it comes with a variety of benefits. Strength training can help improve our overall health, prevent injury, and maintain our independence as we age. The key is to focus on compound exercises, gradually increase the intensity of your workouts, and make sure you're getting enough protein. So, what are you waiting for?

        "evidence": "The OpenBookQA dataset has a collection of questions and four answer choices for each question. The dataset comes with 1326 facts representing an open book. It is expected that answering each question requires at least one of these facts. In addition it requires common knowledge. To obtain relevant common knowledge we use an IR system BIBREF6 front end to a set of knowledge rich sentences. Compared to reading comprehension based QA (RCQA) setup where the answers to a question is usually found in the given small paragraph, in the OpenBookQA setup the open book part is much larger (than a small paragraph) and is not complete as additional common knowledge may be required. This leads to multiple challenges. First, finding the relevant facts in an open book (which is much bigger than the small paragraphs in the RCQA setting) is a challenge. Then, finding the relevant common knowledge using the IR front end is an even bigger challenge, especially since standard IR approaches can be misled by distractions. For example, Table 1 shows a sample question from the OpenBookQA dataset. We can see the retrieved missing knowledge contains words which overlap with both answer options A and B. Introduction of such knowledge sentences increases confusion for the question answering model. Finally, reasoning involving both facts from open book, and common knowledge leads to multi-hop reasoning with respect to natural language text, which is also a challenge.\nCompared to reading comprehension based QA (RCQA) setup where the answers to a question is usually found in the given small paragraph, in the OpenBookQA setup the open book part is much larger (than a small paragraph) and is not complete as additional common knowledge may be required.

        "question": "A computational experiment is used to show that the ability to request information was useful to the agent. However, it seems obvious that an agent with less uncertainty will do better. Section 6 describes the model comparison as comparing the agent that requests assistance to an agent that takes random actions. However, with missing annotations a rational agent that can not request information should still be able to rationally search the graph until the object is found - which seems a more reasonable  performance benchmark.  Alternatively, the authors could compare the current framework to a state-of-the-art agent that can solve the same benchmark problem. Was the indoor object-finding task used in previous work, or as part of benchmark problem sets?",
        "answer": "We are not sure what “rationally search the graph” means. Our \"no assistance\" baselines search the graph with pre-learned knowledge. An approach that exhaustively searches the graph overly exploits the structure of the simulator and may not scale to real continuous environments. We impose a time constraint so the agent cannot simply visit an entire house for each task. Even if the agent performed an exhaustive search, it would still need to detect objects (i.e. learning when to call DONE). This navigation problem is proposed by our paper. We implement a transformer-based model trained with imitation learning, which is a strong baseline for the popular VLN problem (https://arxiv.org/abs/2011.13922). Our task is harder than VLN in that the task command is high-level (“find O in room R” vs “turn left... go to X... stop there”).",
        "evidence": "Problem. We apply HARI to modeling a human-assisted navigation (HAN) problem. In HAN, a human requests an agent to find an object in an indoor environment. Each task request asks the agent to go to a room of type r and find an object of type o (e.g., find a mug in a kitchen). The agent is equipped with a camera and shares its camera view with the human. We assume that the human is sufficiently familiar with the environment that they can recognize the agent's location by looking at its current view. Before issuing a task request, the human imagines a goal location (but do not reveal it to the agent). We are primarily interested in evaluating success in goal-finding, i.e. whether the agent can arrive at the human's intended goal location. Even though there could be multiple locations that match a request, the agent only succeeds if it arrives exactly at the chosen goal location. We also determine success in request-fulfilling, where the agent successfully fulfills a request if it navigates to any node that is within two meters of an object that matches the request.\nWhile an agent is performing a task, it may request the human to provide additional information via telecommunication (e.g., a chat app). Specifically, it can ask for a description of its current location (CUR), the goal location (GOAL), or a subgoal location that is on the path from its current location to the goal location (SUB). Detail about how the subgoals are determined is in the Appendix.\nOperation Environment. We construct the operation environments using the environment graphs provided by the Matterport3D simulator. Each environment graph is generated from a 3D model of a house where each node is a location in the house and each edge connects two nearby unobstructed locations. Each operation state s corresponds to a node in the graph. At any time, the agent's operation action space A consists of traversing to any of the nodes that are adjacent to its current node.\nWe employ a discrete bag-of-features representation for state descriptions. 3 A bag of features represents the information that the agent extracts from the raw input that the agent perceives (e.g., an image, a language sentence). Working with this intermediate input allows us to easily vary the type and amount of information given to the agent. Specifically, we simulate two settings of descriptions: dense and sparse. At evaluation time, the agent perceives sparse descriptions and request the assistant for dense descriptions. A dense description of a current location contains the room name at the location, and the features of M objects restricted to be within δ meters of the location. The features of each object consists of (i) its name, (ii) horizontal and vertical angles (relative to the current viewpoint), and (iii) distance (in meters) from the object to the current location. A dense description of a goal follows the same representation scheme. In the sparse setting, the current-location description does not include the room name. Moreover, we remove the features of objects that are not in the top 100 most frequent objects, emulating an imperfect object detector module. The sparse goal description (the task request) has only features of the target object and the room name where the object is located at. Especially, if a subgoal location is adjacent or coincides with the agent's current location, instead of describing room and object features, the human specifies the ground-truth action to go to the subgoal (an action is specified by its horizontal and vertical angles, and travel distance). 4   Experimental Procedure. We conduct our experiments in three phases. In the pre-training phase, we learn an operation policy π with dense descriptions of the current location and the goal. In the training phase, the agent perceives a sparse description of its current location and is given a sparse initial goal description. We use advantage actor-critic to learn an interaction policy ψ θ that controls how the agent communicates with the human and navigates in an environment. The human always returns dense descriptions. The interaction policy is trained in environments that are previously seen as well as unseen during pre-training. Finally, in the evaluation phase, the interaction policy is tested on three conditions: seen environment and target object type but starting from a new room (UNSEENSTR), seen environment but new target object type (UNSEENOBJ), and new environment (UNSEENENV).\nWe introduce an assistant into the operation environment, who can provide information about the environment's states. We assume the agent possesses a pre-learned operation policy π. This policy serves as the common ground between the agent and the assistant, which is a prerequisite for communication between them to occur. For example, this policy represents a set of basic tasks that agent has mastered and the assistant can ask the agent to perform. In general, the more knowledge encoded in this policy, the more effectively the agent can communicate with and leverage help from the assistant. Our goal is to learn an interaction policy ψ θ (parametrized by θ) that controls how the agent communicates with the assistant to gather additional information. The operation policy π will be invoked by the interaction policy if the latter decides that the agent does not need new information and wants to take an operating action.\nThe assistant aids the agent by giving new (current or goal) state descriptions, connecting the agent to situations on which it can make better decisions. Consider an object-finding navigation problem, where a robot has been trained to reliably navigate to the kitchen from the living room of a house. Suppose the robot is then asked to \"find a mug\", an object that it has never heard of. The assistant can help the robot accomplish this task by giving a more informative goal description \"find a mug in the kitchen\", relating the current task to the kitchen-finding task that the robot has been familiar with. The robot may also have problems with localization: it knows how to get the kitchen from the living room but it may not realize that it is currently the living room. In this case, giving a currentstate description that specifies this information provides the robot with a useful hint on what actions to take next.\nOur framework allows the assistant to convey any form of information that the agent can incorporate into its input. As discussed in §2, the notion of \"state description\" in our framework is general, capturing various types of information, including but not limited to visual perception and verbal description. Communication between the agent and the assistant can be flexibly enriched by designing the agent's operation policy to be able to consume the forms of information of interest (e.g., a policy that takes natural language as input).\nCommunication with the Assistant. The assistant is present all the time and knows the agent's current state s t and the goal state g t . It is specified by two functions: a description function ρ A : S × D → ∆(D) and a subgoal function ω A : S × S → ∆(S). ρ A (d | s, d) specifies the probability of giving d as the new description of state s given a current description d. ω A (g | s, g) indicates the probability of proposing g as a subgoal given a current state s and a goal state g. By selecting among these actions, the interaction policy essentially decides when to ask the assistant for additional information, and what types of information to ask for. Our formulation does not specify the input space of the interaction policy, as this space depends on how the agent implements its goal memory (i.e. how it stores and retrieves the subgoals). In the next section, we introduce an instantiation where the agent uses a stack data structure to manage (sub)goals.\nOur model has two components: an encoder and a decoder; both are implemented as Transformer models (Vaswani et al., 2017).****Operation Environment. We construct the operation environments using the environment graphs\nprovided by the Matterport3D simulator (Anderson et al., 2018). Each environment graph is generated from a 3D model of a house where each node is a location in the house and each edge connects\ntwo nearby unobstructed locations.****We introduce an assistant into the operation environment, who can provide information about the environment’s states.

        "answer": "Posts attract users who hold the same stance to like them – is reliable.",
        "evidence": "We tested the proposed UTCNN on two different datasets: FBFans and CreateDebate. FBFans is a privately-owned, single-topic, Chinese, unbalanced, social media dataset, and CreateDebate is a public, multiple-topic, English, balanced, forum dataset. Results using these two datasets show the applicability and superiority for different topics, languages, data distributions, and platforms.\nThe FBFans dataset contains data from anti-nuclear-power Chinese Facebook fan groups from September 2013 to August 2014, including posts and their author and liker IDs. There are a total of 2,496 authors, 505,137 likers, 33,686 commenters, and 505,412 unique users. Two annotators were asked to take into account only the post content to label the stance of the posts in the whole dataset as supportive, neutral, or unsupportive (hereafter denoted as Sup, Neu, and Uns). Sup/Uns posts were those in support of or against anti-reconstruction; Neu posts were those evincing a neutral standpoint on the topic, or were irrelevant. Raw agreement between annotators is 0.91, indicating high agreement. Specifically, Cohen’s Kappa for Neu and not Neu labeling is 0.58 (moderate), and for Sup or Uns labeling is 0.84 (almost perfect). Posts with inconsistent labels were filtered out, and the development and testing sets were randomly selected from what was left. Posts in the development and testing sets involved at least one user who appeared in the training set. The number of posts for each stance is shown on the left-hand side of Table TABREF12 . About twenty percent of the posts were labeled with a stance, and the number of supportive (Sup) posts was much larger than that of the unsupportive (Uns) ones: this is thus highly skewed data, which complicates stance classification. On average, 161.1 users were involved in one post. The maximum was 23,297 and the minimum was one (the author). For comments, on average there were 3 comments per post. The maximum was 1,092 and the minimum was zero.\nTo test whether the assumption of this paper – posts attract users who hold the same stance to like them – is reliable, we examine the likes from authors of different stances. Posts in FBFans dataset are used for this analysis. We calculate the like statistics of each distinct author from these 32,595 posts. As the numbers of authors in the Sup, Neu and Uns stances are largely imbalanced, these numbers are normalized by the number of users of each stance. Table TABREF13 shows the results. Posts with stances (i.e., not neutral) attract users of the same stance. Neutral posts also attract both supportive and neutral users, like what we observe in supportive posts, but just the neutral posts can attract even more neutral likers. These results do suggest that users prefer posts of the same stance, or at least posts of no obvious stance which might cause annoyance when reading, and hence support the user modeling in our approach.\nThe CreateDebate dataset was collected from an English online debate forum discussing four topics: abortion (ABO), gay rights (GAY), Obama (OBA), and marijuana (MAR). The posts are annotated as for (F) and against (A). Replies to posts in this dataset are also labeled with stance and hence use the same data format as posts. The labeling results are shown in the right-hand side of Table TABREF12 . We observe that the dataset is more balanced than the FBFans dataset. In addition, there are 977 unique users in the dataset. To compare with Hasan and Ng's work, we conducted five-fold cross-validation and present the annotation results as the average number of all folds BIBREF9 , BIBREF5 .\nThe FBFans dataset has more integrated functions than the CreateDebate dataset; thus our model can utilize all linguistic and extra-linguistic features. For the CreateDebate dataset, on the other hand, the like and comment features are not available (as there is a stance label for each reply, replies are evaluated as posts as other previous work) but we still implemented our model using the content, author, and topic information.\nTo test whether the assumption of this paper – posts attract users who hold the same stance to like them – is reliable, we examine the likes from authors of different stances.",

Janzing assumes access to infinite data in each domain (we assume a finite training set), uses a non-standard measure of model complexity (we use Rademacher complexity), and restricts analysis to problems with a specific causal structure, while we make no causal structure assumption. The former means that the wide range of existing tools to measure or constrain Rademacher complexity for diverse model classes can be used with ours, but not Janzing’s. The latter means that our analysis is more generally applicable to diverse problems. Moreover, it is unclear whether the object they bound (expected risk under the interventional distribution) is equivalent to what we bound (expected risk across all domains). We have added discussion of this paper (and others) to our related work section.",
        "evidence": "Theoretical Analysis of the DG Setting and Algorithms The DG problem setting was first analysed in. Since then there have been some attempts to analyse DG algorithms from a generalisation bound perspective. However these studies have theoretical results that are either restricted to specific model classes, such as kernel machines, or make strong assumptions about how the domains seen during training will resemble those seen at test time-e.g., that all domains are convex combinations of a finite pre-determined set of prototypical domains. In contrast, our Rademacher complexity approach can be applied to a broad range of model classes (including neural networks), and makes comparatively milder assumptions about the relationship between domains-i.e., they are i.i.d. samples from another arbitrary distribution over domains.\nThe majority of the existing work investigating the theoretical foundations of DG follow the initial formalisation of the domain generalisation problem put forth by, where the goal is to minimise the expected error over unseen domains. However, several recent works have also explored the idea of bounding the error on a single unseen domain with the most pathological distribution shift. This type of analysis is typically rooted in methods from causal inference, rather than statistical learning theory. As a consequence, they are able to make stronger claims for the problems they address, but the scope of their analysis is necessarily limited to the scenarios where their assumptions about the underlying causal structures are valid. For example, Janzing (2019) provides bounds that assume problems conform to a specific class of structural equation models, and the analysis is performed under the assumption that infinite training data is available within each of the observed training domains. Throughout the work we address the stan-dard DG formalisation given by, where one is concerned with the expected performance of a model on domains sampled from some distribution over domains.\nOthers rely on trying to link between domain adaptation objectives (where target domains are observable for alignment to source domains) and domain generalisation (where target domains are not observable and thus cannot correctly be used in a learning objective). proceed by making assumptions on the structure of the distribution over possible domains (i.e., that it has support determined by the convex hull of a finite set of prototypical domains), which allows them to upper bound the domain alignment metric. provide a bound that depends on an unobservable domain distance quantity, which they then approximate in experiments using kernel density estimates. is another piece of work that theoretically investigates the generalisation of ERM in a DG setting. They deal with online DG, where each time-step corresponds to observing a new domain, and the learner must produce a new model capable of generalising to novel domains. Another point of difference between their work and the standard DG problem setting of is that the domain at each time-step is chosen by an adversary. They analyse this game for a finite number of time-steps, but they assume each domain has an infinite amount of data. They also put some limitations on the adversary: e.g., it must choose a domain that is a convex combination of a finite number of pre-determined domains. In contrast, our theoretical analysis is in the more realistic setting where one has a finite amount of data per domain, and the domains we consider are not limited to convex combinations of a set of prototypical domains. Possibly the most similar work to our theoretical contributions is due to, who also provide learningtheoretic generalisation bounds for DG. However, their analysis only applies to finite hypothesis classes (which does not include, e.g., linear models or neural networks), whereas ours can be applied to any class amenable to analysis with Rademacher complexity.\nThe main existing empirical analysis on DG is, who compared several state of the art DG methods under a common evaluation and hyper-parameter tuning protocol called DomainBed. They ultimately defend Empirical Risk Minimization (ERM) over more sophisticated alternatives on the grounds that no competitor consistently beats it across the benchmark suite. We also broadly defend ERM, and build on the same benchmark, but differently we provide a much deeper analysis into when and why ERM works. More specifically: (i) We provide a new theoretical analysis of ERM's generalisation quality unlike the prior purely empirical evaluation, (ii) We re-use the DomainBed benchmark to directly corroborate this theory under controlled conditions using linear models where model complexity can be tractably and accurately tuned. (iii) We use our complexity-based analysis to explain the previously erratic results of prior DomainBed competitors in terms of model complexity. (iv) We identify, and empirically validate, the preferred model selection criterion for DG, a point which was inconclusive in.\nHowever, several recent works have also explored the idea of bounding the error on a single unseen domain with the most pathological distribution shift (Janzing, 2019). This type of analysis is typically rooted in methods from causal inference, rather than statistical learning theory. As a consequence, they are able to make stronger claims for the problems they address, but the scope of their analysis is necessarily limited to the scenarios where their assumptions about the underlying causal structures are valid.

The approach does not rely on pre-trained vectors, which provides a serious advantage when dealing with short messages of this kind. More specifically, users will often prefer to obfuscate their offensive terms using shorter slang words or create new words by `inventive' spelling and word concatenation. For instance, the word `Islamolunatic' is not available in the popular pre-trained word embeddings (Word2Vec or GloVe), even though it appears with a rather high frequency in racist postings. Hence, word frequency vectorization is preferable to the pre-trained word embeddings used in prior works if one aims to build a language-agnostic solution.\nWe believe that deep learning models have a high potential wrt. classifying text or analyzing the sentiment in general. In our opinion there is still space for further improving the classification algorithms.\nFor future work we plan to investigate other sources of information that can be utilized to detect hateful messages.

We hypothesise that the lower performance (in contrast with the results reported in BIBREF2) is caused by the size of the training data, because we train the word2vec WE on considerably larger dataset than the Czech Flair model. However, when WE and Flair embeddings are combined, performance moderately increases, demonstrating that the two embedding methods produce at least partially complementary representations.\nTable TABREF44 compares our best model with state-of-the-art results on PDT 2.0 (note that some of the related work used only a subset of PDT 2.0 and/or utilized gold morphological annotation).

Consumers can use an offset to track read messages.\n- Brokers: A Kafka cluster is composed of one or more brokers that manage the storage of messages in topics and serve as intermediaries between producers and consumers.\n- Producers: Applications that produce data and publish it to one or more topics in a Kafka cluster. They control how events are assigned to partitions within a topic.\n- Consumers: Applications that subscribe to one or more topics and consume published messages. The only metadata retained on a per-consumer basis is the offset or position of that consumer in a topic. This offset is controlled by the consumer.\n- Partitions: Kafka uses partitions to split a topic's messages across multiple brokers for scalability and performance. Events with the same event key, such as the same customer identifier or vehicle ID, are written to the same partition, and Kafka guarantees that any consumer of a given topic partition will always read that partition’s events in exactly the same order as they were written.\n- Replication: Multiple brokers always have a copy of the data to guarantee high availability and fault tolerance.

        "evidence": "Learning semantic representations (embeddings) of different entities, such as textual, commercial, and physical, has been a recent and active area of research. Such representations can facilitate applications that rely on a notion of similarity, for example recommendation systems and ranking algorithms in e-commerce.\nIn natural language processing, word2vec BIBREF0 learns vector representations of words from large quantities of text, where each word is mapped to a $d$-dimensional vector such that semantically similar words have geometrically closer vectors. This is achieved by predicting either the context words appearing in a window around a given target word (skip-gram model), or the target word given the context (CBOW model). The main assumption is that words appearing frequently in similar contexts share statistical properties (the distributional hypothesis). Crucially, word2vec models, like many other word embedding models, preserve sequential information encoded in text so as to leverage word co-occurrence statistics. The skip-gram model has been adapted to other domains in order to learn dense representations of items other than words. For example, product embeddings in e-commerce BIBREF1 or vacation rental embeddings in the hospitality domain BIBREF2 can be learned by treating purchase histories or user click sequences as sentences and applying a word2vec approach.\nMost of the prior work on item embedding exploit the co-occurrence of items in a sequence as the main signal for learning the representation. One disadvantage of this approach is that it fails to incorporate rich structured information associated with the embedded items. For example, in the travel domain, where we seek to embed hotels and other travel-related entities, it could be helpful to encode explicit information such as user ratings, star ratings, hotel amenities, and location in addition to implicit information encoded in the click-stream.\nIn this work, we propose an algorithm for learning hotel embeddings that combines sequential user click information in a word2vec approach with additional structured information about hotels. We propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes. In experimental results, we show that enhancing the neural network to jointly encode click and supplemental structured information outperforms a skip-gram model that encodes the click information alone. The proposed architecture also naturally handles the cold-start problem for hotels with little or no historical clicks. Specifically, we can infer an embedding for these properties by leveraging their supplemental structured metadata.\nCompared to previous work on item embeddings, the novel contributions of this paper are as follows:\nWe propose a novel framework for fusing multiple sources of information about an item (such as user click sequences and item-specific information) to learn item embeddings via self-supervised learning.\nWe generate an interpretable embedding which can be decomposed into sub-embeddings for clicks, location, ratings, and attributes, and employed either as separate component embeddings or a single, unified embedding.\nIt is also dynamic, meaning it is easy to reflect future changes in attributes such as star-rating or addition of amenities in the embedding vectors without retraining.\nWe address the cold-start problem by including hotel metadata which are independent of user click-stream interactions and available for all hotels. This helps us to better impute embeddings for sparse items/hotels.\nWe show significant gains over previous work based on click-embedding in several experimental studies.\nThe structure of the remainder of this paper is as follows. Section 2 gives an overview of some of the recent works on neural embedding. Section 3 provides details of the proposed framework, including the neural network architecture, training methodology, and how the cold-start problem is addressed. In Section 4, we present experimental results on several different tasks and a comparison with previous state-of-the-art work. Section 5 concludes the paper.\nWe propose a neural architecture that adopts and extends the skip-gram model to accommodate arbitrary relevant information of embedded items, including but not limited to geographic information, ratings, and item attributes.",

        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation. Section SECREF3 describes our test suite. The context-aware models we use in our experiments are detailed in Section SECREF4 . We discuss our experiments in Section SECREF5 and the results in Section SECREF6 .\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns.",

        "answer": "Have you ever thought about where your plastic water bottles go? It probably ends up in a landfill, where it will decompose for over 1000 years as it deposits toxic chemicals. Plastic is an invention that has done more harm than good. There are about 363,762,732,605 pounds of plastic covering the earth. Most of this plastic can’t be recycled. Although people think it is too expensive or inconvenient to get rid of plastics, we should reduce the amount of plastic used or increase the price of plastics. One reason is that when plastic invades a balanced ecosystem, it corrupts it completely. The marine biome is one that is affected by this product. The animals in the ocean die of suffocation, ingestion of plastics, and entanglement. The animals affected are seagulls, whales, seals, fish, and turtles, and that's just a few. The animals eat so much plastic that they die of constipation from it. Another reason is the presence of microplastics in food and people. About 99% of fish have microplastics in their stomachs, livers, and filets (the meat of fish). Approximately 80% of cows have microplastics in their meat and milk. A good point is that mealworms and waxworms are studied to digest plastics, and they should be added to landfills to break down plastics. There are about 50,000 particles of plastic in an adult person, and this number is rising fast. Third, most plastic is littered. There are about 10 million tons of plastic litter every year. Every week, you ingest about a credit card's worth of plastic. There are about 44 million pounds of plastic that are produced that is very deadly to the environment.\"The plastic in the environment is in your water, food, and body. These plastics should not be there; they can lead to cancer, according to a recent study. We need to stop using plastic in our lives. Some ways we can reduce the amount of plastic on earth are by using sustainable materials such as wood, plant fibers, and mushroom styrofoam. We can also try to buy recyclable plastics that have a triangle formed by three cycling arrows. Use a tote bag instead of a plastic one, or a metal and glass straw instead of a plastic one. You can also use a metal cutlery kit instead of plastic. These are all ways you can make a difference in your everyday life.",

        "evidence": "When the modern Olympics began in 1896, the initiators and organizers were looking for a great popularizing event, recalling the glory of ancient Greece. The idea of a marathon race came from Michel Bréal, who wanted the event to feature in the first modern Olympic Games in 1896 in Athens. This idea was heavily supported by Pierre de Coubertin, the founder of the modern Olympics, as well as by the Greeks. The Greeks staged a selection race for the Olympic marathon on 22 March 1896 (Gregorian) that was won by Charilaos Vasilakos in 3 hours and 18 minutes (with the future winner of the introductory Olympic Games marathon, Spyridon \"Spyros\" Louis, coming in fifth at a second race two weeks later). The winner of the first Olympic marathon, on 10 April 1896 (a male-only race), was Spyridon Louis, a Greek water-carrier, in 2 hours 58 minutes and 50 seconds. The marathon of the 2004 Summer Olympics was run on the traditional route from Marathon to Athens, ending at Panathinaiko Stadium, the venue for the 1896 Summer Olympics. That men's marathon was won by Italian Stefano Baldini in 2 hours 10 minutes and 55 seconds, a record time for this route until the non-Olympics Athens Classic Marathon of 2014, when Felix Kandie lowered the course record to 2 hours 10 minutes and 37 seconds.",

A statistical language model estimates the probability of a sequence of words or an upcoming word. An N-gram is a contiguous sequence of N words: a unigram is a single word, a bigram is a two-word sequence, and a trigram is a three-word sequence. For example, in the tweet\ntears in Ramen #SingleLifeIn3Words\n“tears”, “in”, “Ramen” and “#SingleLifeIn3Words” are unigrams; “tears in”, “in Ramen” and “Ramen #SingleLifeIn3Words” are bigrams and “tears in Ramen” and “in Ramen #SingleLifeIn3Words” are trigrams.\nAn N-gram model can predict the next word from a sequence of N-1 previous words. A trigram Language Model (LM) predicts the conditional probability of the next word using the following approximation: DISPLAYFORM0 \nThe assumption that the probability of a word depends only on a small number of previous words is called a Markov assumption BIBREF8 . Given this assumption the probability of a sentence can be estimated as follows: DISPLAYFORM0 \nIn a study on how phrasing affects memorability, BIBREF9 take a language model approach to measure the distinctiveness of memorable movie quotes. They do this by evaluating a quote with respect to a “common language” model built from the newswire sections of the Brown corpus BIBREF10 . They find that movie quotes which are less like “common language” are more distinctive and therefore more memorable. The intuition behind our approach is that humor should in some way be memorable or distinct, and so tweets that diverge from a “common language” model would be expected to be funnier.\nIn order to evaluate how funny a tweet is, we train language models on two datasets: the tweet data and the news data. Tweets that are more probable according to the tweet data language model are ranked as being funnier. However, tweets that have a lower probability according to the news language model are considered the funnier since they are the least like the (unfunny) news corpus. We relied on both bigrams and trigrams when training our models.\nWe use KenLM BIBREF11 as our language modeling tool. Language models are estimated using modified Kneser-Ney smoothing without pruning. KenLM also implements a back-off technique so if an N-gram is not found, KenLM applies the lower order N-gram's probability along with its back-off weights.\nAn N-gram is a contiguous sequence of N words: a unigram is a single word, a bigram is a two-word sequence, and a trigram is a three-word sequence.",

For example, for text classification problem, different sets of features have been considered in different works (spanning a history of more than twenty years) including `bag of words', `bag of phrases', `bag of n-grams', `WordNet based word generalizations', and `word embeddings' BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7. Even for recent end-to-end designs using deep neural networks, specification of core features remains manually driven BIBREF8, BIBREF9. During feature engineering, often data scientists manually determine which features to use based upon their experience and expertise with respect to the underlying application domain as well as state-of-the-art tools and techniques. Different tools (e.g., NLTK BIBREF10, Mallet BIBREF11, Stanford CoreNLP BIBREF12, Apache OpenNLP BIBREF13, Apache Lucene BIBREF14, etc.) available to a NLP data scientist for TA application design and development often differ in terms of support towards extraction of features, level of granularity at which feature extraction process is to be specified; and these tools often use different programing vocabularies to specify semantically equivalent features.\nCurrently, there is no generic method or approach, which can be applied during TA application's design process to define and extract features for any arbitrary application in an automated or semi-automated manner. Even there is no single way to express wide range of NLP features, resulting into increased efforts during feature engineering which has to start new for each data scientist and automated reuse of features across semantically similar or related applications designed by different data scientists is difficult. This also hinders foundational studies on NLP feature engineering including why certain features are more critical than others.\nIn this paper, we aim to present an approach towards automating NLP feature engineering. We start with an outline of a language for expressing NLP features abstracting over the feature extraction process, which often implicitly captures intent of the NLP data scientist to extract specific features from given input text. We next discuss a method to enable automated reuse of features across semantically related applications when a corpus of feature specifications for related applications is available. Proposed language and system would help achieving reduction in manual effort towards design and extraction of features, would ensure standardization in feature specification process, and could enable effective reuse of features across similar and/or related applications.\nCurrently, there is no generic method or approach, which can be applied during TA application’s design process to define and extract features for any arbitrary application in an automated or semi-automated manner.",

Although word embeddings are widely used across NLP, their stability has not yet been fully evaluated and understood. In this paper, we explore the factors that play a role in the stability of word embeddings, including properties of the data, properties of the algorithm, and properties of the words. We find that word embeddings exhibit substantial instabilities, which can have implications for downstream tasks.\nUsing the overlap between nearest neighbors in an embedding space as a measure of stability (see sec:definingStability below for more information), we observe that many common embedding spaces have large amounts of instability. For example, Figure FIGREF1 shows the instability of the embeddings obtained by training word2vec on the Penn Treebank (PTB) BIBREF4 . As expected, lower frequency words have lower stability and higher frequency words have higher stability. What is surprising however about this graph is the medium-frequency words, which show huge variance in stability. This cannot be explained by frequency, so there must be other factors contributing to their instability.\nIn the following experiments, we explore which factors affect stability, as well as how this stability affects downstream tasks that word embeddings are commonly used for.

Algorithms that exploit structure in the real world through effective inductive biases are key to solving this problem. Several inductive biases have been successfully used in the past, from early work using translational invariance for developing, to recent data augmentations for developing multiple self-supervised algorithms. A key inductive bias in multiple works is sparsity of concepts. Essentially, it refers to how objects in the real world tend to interact and affect the dynamics of other objects only in a small neighbourhood. Consider for example picking up a pen. This simple task only changes the dynamics of a very small part of the world, namely the pen and the hand of the person grasping it. Exploiting such structure allows learning representations that can generalize better in the real world.\nIn this paper, we develop a method that exploits sparsity by learning minimal representations. The well known saying 'neurons that fire together wire together' points to the phenomenon that that neurons that have similar output for a given input also have strong weights between them. Ideally, given the same set of neurons to model certain concepts, we would want neurons that relate to a particular concept to have strengthened weights while those relating to another concept to have weakened weights. Therefore, low correlation in the outputs of the representation would lead to less redundancy in modelling concepts and thus better generalization. This is precisely the motivation behind minimality leading to sparse representations and improved generalization. Minimal representations refer to ones that have sufficient but minimal information w.r.t. the task at hand. Therefore, it must be only possible to solve the task in hand and no other task, thus leading to better generalization for the given task. Another viewpoint is that minimal representations also lead to a reduction in spurious correlations. Since there is minimal noise present in the representation to cause spurious correlations, this again results in better generalization.\nFaster LR Standard LR Slower LR Figure: Model Invariance (MODINV) A common representation f θ supports multiple predictor heads, each with a different learning rate. Each head is optimized based on the task objective (e.g., SSL loss) and captures different spurious correlations. As diversification in learning of predictor heads increases, the common representation must be optimal to reduce the loss for all predictors. 'Red' denotes the head being trained for the current sample.\nOur approach, which we call model invariance (MODINV), learns minimal representations by incorporating multiple predictors over a single, common representation for a given task (see Figure). Each predictor head is then trained independently (a given sample only trains one head) and with a learning rate different to other heads. Theoretically, this can be looked at as a manifestation of the information bottleneck principle, which balances between sufficiency and minimality. Intuitively, this can be looked at as providing robustness to spurious correlations. Since each head learns a different prediction (based on its own optimization and learning on different parts of data set), each head is susceptible to different spurious correlations. However, since there is only one common representation to support all the predictor heads, this representation must be robust to any spurious correlations as training progresses.\nWe evaluate our method on two separate settings; 1) Reinforcement Learning: The DeepMind Control Suite(DMC) benchmark with distractors, which involves natural video playing in the background while the agent is controlled in the foreground and 2) Vision: The CIFAR-10 ( datasets, where no labels are used for learning the representations, followed by the standard linear probing evaluation protocol to test generalization.\nWe introduce MODINV, a simple method motivated by incorporating sparsity in representations, while showing connections to the information bottleneck principle. MODINV is conceptually simple, easy to implement, and improves representation learning performance in both reinforcement learning (from pixels) and vision settings. In reinforcement learning, MODINV achieves stronger than state-of-the-art performance on the DMC Suite with distractors benchmark, both with augmentations and without. In vision, MODINV leads to better performance than the baseline method of SIMSIAM when using a linear predictor on both CIFAR-10 and STL-10 datasets.\nOur approach, which we call model invariance (MODINV), learns minimal representations by incorporating multiple predictors over a single, common representation for a given task (see Figure 1). Each predictor head is then trained independently (a given sample only trains one head) and with a learning rate different to other heads.

        "answer": "A neural attention model.",
        "evidence": "The need to access and digest large amounts of textual data has provided strong impetus to develop automatic summarization systems aiming to create shorter versions of one or more documents, whilst preserving their information content. Much effort in automatic summarization has been devoted to sentence extraction, where a summary is created by identifying and subsequently concatenating the most salient text units in a document.\nMost extractive methods to date identify sentences based on human-engineered features. These include surface features such as sentence position and length BIBREF0 , the words in the title, the presence of proper nouns, content features such as word frequency BIBREF1 , and event features such as action nouns BIBREF2 . Sentences are typically assigned a score indicating the strength of presence of these features. Several methods have been used in order to select the summary sentences ranging from binary classifiers BIBREF3 , to hidden Markov models BIBREF4 , graph-based algorithms BIBREF5 , BIBREF6 , and integer linear programming BIBREF7 .\nIn this work we propose a data-driven approach to summarization based on neural networks and continuous sentence features. There has been a surge of interest recently in repurposing sequence transduction neural network architectures for NLP tasks such as machine translation BIBREF8 , question answering BIBREF9 , and sentence compression BIBREF10 . Central to these approaches is an encoder-decoder architecture modeled by recurrent neural networks. The encoder reads the source sequence into a list of continuous-space representations from which the decoder generates the target sequence. An attention mechanism BIBREF11 is often used to locate the region of focus during decoding.\nWe develop a general framework for single-document summarization which can be used to extract sentences or words. Our model includes a neural network-based hierarchical document reader or encoder and an attention-based content extractor. The role of the reader is to derive the meaning representation of a document based on its sentences and their constituent words. Our models adopt a variant of neural attention to extract sentences or words. Contrary to previous work where attention is an intermediate step used to blend hidden units of an encoder to a vector propagating additional information to the decoder, our model applies attention directly to select sentences or words of the input document as the output summary. Similar neural attention architectures have been previously used for geometry reasoning BIBREF12 , under the name Pointer Networks.\nOne stumbling block to applying neural network models to extractive summarization is the lack of training data, i.e., documents with sentences (and words) labeled as summary-worthy. Inspired by previous work on summarization BIBREF7 , BIBREF13 and reading comprehension BIBREF9 we retrieve hundreds of thousands of news articles and corresponding highlights from the DailyMail website. Highlights usually appear as bullet points giving a brief overview of the information contained in the article (see Figure 1 for an example). Using a number of transformation and scoring algorithms, we are able to match highlights to document content and construct two large scale training datasets, one for sentence extraction and the other for word extraction. Previous approaches have used small scale training data in the range of a few hundred examples.\nOur work touches on several strands of research within summarization and neural sequence modeling. The idea of creating a summary by extracting words from the source document was pioneered in bankoetal00 who view summarization as a problem analogous to statistical machine translation and generate headlines using statistical models for selecting and ordering the summary words. Our word-based model is similar in spirit, however, it operates over continuous representations, produces multi-sentence output, and jointly selects summary words and organizes them into sentences. A few recent studies BIBREF14 , BIBREF15 perform sentence extraction based on pre-trained sentence embeddings following an unsupervised optimization paradigm. Our work also uses continuous representations to express the meaning of sentences and documents, but importantly employs neural networks more directly to perform the actual summarization task.\nrush2015neural propose a neural attention model for abstractive sentence compression which is trained on pairs of headlines and first sentences in an article. In contrast, our model summarizes documents rather than individual sentences, producing multi-sentential discourse. A major architectural difference is that our decoder selects output symbols from the document of interest rather than the entire vocabulary. This effectively helps us sidestep the difficulty of searching for the next output symbol under a large vocabulary, with low-frequency words and named entities whose representations can be challenging to learn. Gu:ea:16 and gulcehre2016pointing propose a similar “copy” mechanism in sentence compression and other tasks; their model can accommodate both generation and extraction by selecting which sub-sequences in the input sequence to copy in the output.\nWe evaluate our models both automatically (in terms of Rouge) and by humans on two datasets: the benchmark DUC 2002 document summarization corpus and our own DailyMail news highlights corpus. Experimental results show that our summarizers achieve performance comparable to state-of-the-art systems employing hand-engineered features and sophisticated linguistic constraints.\nrush2015neural propose a neural attention model for abstractive sentence compression which is trained on pairs of headlines and first sentences in an article.

Algeria borders Morocco to the east and southeast, though the border between the two countries has been closed since 1994.\n\nSpanish territory in Northwest Africa neighbouring Morocco comprises five enclaves on the Mediterranean coast: Ceuta, Melilla, Peñón de Vélez de la Gomera, Peñón de Alhucemas, the Chafarinas islands, and the disputed islet Perejil. Off the Atlantic coast the Canary Islands belong to Spain, whereas Madeira to the north is Portuguese. To the north, Morocco is bordered by the Strait of Gibraltar, where international shipping has unimpeded transit passage between the Atlantic and Mediterranean.\n\nThe Rif mountains stretch over the region bordering the Mediterranean from the north-west to the north-east. The Atlas Mountains run down the backbone of the country, from the northeast to the southwest. Most of the southeast portion of the country is in the Sahara Desert and as such is generally sparsely populated and unproductive economically.",

        "question": "What model do they use for generating an opinion summary?",
        "answer": "An abstractive model.",
        "evidence": "The proliferation of opinions expressed in online reviews, blogs, internet forums, and social media has created a pressing need for automated systems which enable customers, companies, or service providers to make informed decisions without having to absorb large amounts of opinionated text. Opinion summarization is the task of automatically generating summaries for a set of opinions about a specific target BIBREF0. Figure FIGREF1 shows various reviews about the movie “Coach Carter” and example summaries generated by humans and automatic systems. The vast majority of previous work BIBREF1 views opinion summarization as the final stage of a three-step process involving: (1) aspect extraction (i.e., finding features pertaining to the target of interest, such as battery life or sound quality); (2) sentiment prediction (i.e., determining the sentiment of the extracted aspects); and (3) summary generation (i.e., presenting the identified opinions to the user). Textual summaries are created following mostly extractive methods which select representative segments (usually sentences) from the source text BIBREF2, BIBREF3, BIBREF4, BIBREF5. Despite being less popular, abstractive approaches seem more appropriate for the task at hand as they attempt to generate summaries which are maximally informative and minimally redundant without simply rearranging passages from the original opinions BIBREF6, BIBREF7, BIBREF8, BIBREF9. General-purpose summarization approaches have recently shown promising results with end-to-end models which are data-driven and take advantage of the success of sequence-to-sequence neural network architectures. Most approaches BIBREF10, BIBREF11, BIBREF12, BIBREF13 encode documents and then decode the learned representations into an abstractive summary, often by attending to the source input BIBREF14 and copying words from it BIBREF15. Under this modeling paradigm, it is no longer necessary to identify aspects and their sentiment for the opinion summarization task, as these are learned indirectly from training data (i.e., sets of opinions and their corresponding summaries). These models are usually tested on domains where the input is either one document or a small set of documents. However, the number of opinions tends to be very large (150 for the example in Figure FIGREF1). It is therefore practically unfeasible to train a model in an end-to-end fashion, given the memory limitations of modern hardware. As a result, current approaches BIBREF16, BIBREF17, BIBREF18, BIBREF19 sacrifice end-to-end elegance in favor of a two-stage framework which we call Extract-Abstract: an extractive model first selects a subset of opinions and an abstractive model then generates the summary while conditioning on the extracted subset (see Figure FIGREF5). The extractive pass unfortunately has two drawbacks. Firstly, on account of having access to a subset of opinions, the summaries can be less informative and inaccurate, as shown in Figure FIGREF1. And secondly, user preferences cannot be easily taken into account (e.g., the reader may wish to obtain a summary focusing on the acting or plot of a movie as opposed to a general-purpose summary) since more specialized information might have been removed.\nIn this paper, we propose Condense-Abstract, an alternative two-stage framework which uses all input documents when generating the summary (see Figure FIGREF5). We view the opinion summarization problem as an instance of multi-source transduction BIBREF20; we first represent the input documents as multiple encodings, aiming to condense their meaning and distill information relating to sentiment and various aspects of the target being reviewed. These condensed representations are then aggregated using a multi-source fusion module based on which an opinion summary is generated using an abstractive model. We also introduce a zero-shot customization technique allowing users to control important aspects of the generated summary at test time. Our approach enables controllable generation while leveraging the full spectrum of opinions available for a specific target. We perform experiments on a dataset consisting of movie reviews and opinion summaries elicited from the Rotten Tomatoes website (BIBREF16; see Figure FIGREF1). Our framework outperforms state-of-the-art models by a large margin using automatic metrics and in a judgment elicitation study. We also verify that our zero-shot customization technique can effectively generate need-specific summaries.\nThese condensed representations are then aggregated using a multi-source fusion module based on which an opinion summary is generated using an abstractive model.",

        "question": "What method do they propose in their paper?",
        "answer": "An effective method to incorporate a phrase table as recommendation memory into Neural Machine Translation (NMT) system.",
        "evidence": "The past several years have witnessed a significant progress in Neural Machine Translation (NMT). Most NMT methods are based on the encoder-decoder architecture BIBREF0 , BIBREF1 , BIBREF2 and can achieve promising translation performance in a variety of language pairs BIBREF3 , BIBREF4 , BIBREF5 .\nHowever, recent studies BIBREF6 , BIBREF7 show that NMT often generates words that make target sentences fluent, but unfaithful to the source sentences. In contrast, traditional Statistical Machine Translation (SMT) methods tend to rarely make this kind of mistakes. Fig. 1 shows an example that NMT makes mistakes when translating the phrase “jinkou dafu xiahua (the sharp decline in imports)” and the phrase “maoyi shuncha (the trade surplus)”, but SMT can produce correct results when translating these two phrases. BIBREF6 argues that the reason behind this is the use of distributed representations of words in NMT makes systems often generate words that seem natural in the context, but do not reflect the content of the source sentence. Traditional SMT can avoid this problem as it produces the translations based on phrase mappings.\nTherefore, it will be beneficial to combine SMT and NMT to alleviate the previously mentioned problem. Actually, researchers have made some effective attempts to achieve this goal. Earlier studies were based on the SMT framework, and have been deeply discussed in BIBREF8 . Later, the researchers transfers to NMT framework. Specifically, coverage mechanism BIBREF9 , BIBREF10 , SMT features BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 and translation lexicons BIBREF6 , BIBREF16 , BIBREF17 have been fully explored. In contrast, phrase translation table, as the core of SMT, has not been fully studied. Recently, BIBREF18 and BIBREF19 explore the possibility of translating phrases in NMT. However, the “phrase” in their approaches are different from that used in phrase-based SMT. In BIBREF18 's models, the phrase pair must be a one-to-one mapping with a source phrase having a unique target phrase (named entity translation pairs). In BIBREF19 's models, the source side of a phrase pair must be a chunk. Therefore, it is still a big challenge to incorporate any phrase pair in the phrase table into NMT system to alleviate the unfaithfulness problem.\nIn this paper, we propose an effective method to incorporate a phrase table as recommendation memory into the NMT system. To achieve this, we add bonuses to the words in recommendation set to help NMT make better predictions. Generally, our method contains three steps. 1) In order to find out which words are worthy to recommend, we first derive a candidate target phrase set by searching the phrase table according to the input sentence. After that, we construct a recommendation word set at each decoding step by matching between candidate target phrases and previously translated target words by NMT. 2) We then determine the specific bonus value for each recommendable word by using the attention vector produced by NMT and phrase translation probability extracted from phrase table. 3) Finally we integrate the word bonus value into the NMT system to improve the final results.\nIn this paper, we make the following contributions:\n1) We propose a method to incorporate the phrase table as recommendation memory into NMT system. We design a novel approach to find from the phrase table the target words worthy of recommendation, calculate their recommendation scores and use them to promote NMT to make better predictions.\n2) Our empirical experiments on Chinese-English translation and English-Japanese translation tasks show the efficacy of our methods. For Chinese-English translation, we can obtain an average improvement of 2.23 BLEU points. For English-Japanese translation, the improvement can reach 1.96 BLEU points. We further find that the phrase table is much more beneficial than bilingual lexicons to NMT.\nIn this paper, we propose an effective method to incorporate a phrase table as recommendation memory into the NMT system.",

His advisor Lu Su secured an alliance with Liu Bei, himself a recent refugee from the north, and Zhou Yu was placed in command of Sun Quan's navy, along with a veteran general who served the Sun family, Cheng Pu. Their combined armies of 50,000 met Cao Cao's fleet and 200,000-strong force at Red Cliffs that winter. Cao Cao had to cross the mighty Yangtze River. So when he along with his fleet sailed down the river, many of his men fell to exhaustion, disease and the northerners were not very comfortable on ships and the marshy terrain. So when the two sides met for war at Wulin, Cao Cao wasn’t able to inflict any defeat on the Allied Force. On the other hand, General Huang Gai of Sun Quan’s army came up with a sneaky plan. He sent a forged letter to Cao Cao, stating that he and others wanted to inflict to his side and they would also bring some of the finest ships of the allies. But little did Cao know that the ships were full of flammable reeds. So when they sailed and approached his fleet, they were set alight and they destroyed Cao Cao’s fleet and camps. Seeing the hopeless situation, Cao Cao ordered his army for a difficult retreat through the Marshlands, during which more of his men fell to disease and exhaustion.

It is situated 4.5 miles (7.2 km) southwest of Middle Palisade, 3.5 miles (5.6 km) southeast of Giraud Peak, and one mile north-northwest of line parent Observation Peak. Mt. Shakspere ranks as the 384th-highest summit in California, and topographic relief is significant as the summit rises over 3,500 feet (1,100 meters) above Palisade Creek in approximately one mile (1.6 km). The first ascent of the summit was made July 20, 1930, by Francis P. Farquhar, Mary Lou Michaels, Doris Drust, Lorna Kilgariff, and Robert L. Lipman.

        "answer": "All the light in our daytime sky comes from the sun, and our sun produces light in many different colors. To understand this, just think of a prism.  White light enters, and a rainbow of colors exits. Our sun is like that. Its light may seem uniform but it is actually emitting many different colors.\n\nOur sky though is not a mix of blue and red and green because the earth's atmosphere is sandwiched between the sun and us, getting in the way. Atmospheric gases and particles scatter the incoming colors, bouncing them in all different directions.  The amount of scattering increases as the wavelength of light decreases.  Red light which has a long wavelength is scattered much less than blue light which has a short wavelength. As blue is scattered more, it fills our daytime sky.\n\nAs the sun traverses the sky and moves low on the horizon, the light that reaches our eyes must actually travel further through the atmosphere.  This has the effect of completely bouncing away all the blue light.  We are left with the reds and yellows and oranges in wonderful mixture, making sunrises and sunsets so beautiful.",

        "evidence": "First, we evaluated the standard HMM model with an uninformative prior (this will be our baseline) for the two different input features: MFCC (and derivatives) and MBN. Results are shown in Table TABREF20 . Surprisingly, the MBN features perform relatively poorly compared to the standard MFCC. These results are contradictory to those reported in BIBREF3 . Two factors may explain this discrepancy: the Mboshi5k data being different from the training data of the MBN neural network, the neural network may not generalize well. Another possibility may be that the initialization scheme of the model is not suitable for this type of features. Indeed, Variational Bayesian Inference algorithm converges only to a local optimum of the objective function and is therefore dependent of the initialization. We believe the second explanation is the more likely since, as we shall see shortly, the best results in term of word segmentation and NMI are eventually obtained with the MBN features when the inference is done with the informative prior. Next, we compared the HMM and the SVAE models when trained with an uninformative prior (lines with \"Inf. Prior\" set to \"no\" in Table TABREF23 ). The SVAE significantly improves the NMI and the precision showing that it extracts more consistent units than the HMM model. However, it also degrades the segmentation in terms of recall. We further investigated this behavior by looking at the duration of the units found by both models compared to the true phones (Table TABREF22 ). We observe that the SVAE model favors longer units than the HMM model hence leading to fewer boundaries and consequently smaller recall.\nWe then evaluated the effect of the informative prior on the acoustic unit discovery (Table TABREF23 ). On all 4 combinations (2 features sets INLINEFORM0 2 models) we observe an improvement in terms of precision and NMI but a degradation of the recall. This result is encouraging since the informative prior was trained on English data (TIMIT) which is very different from Mboshi. Indeed, this suggests that even speech from an unrelated language can be of some help in the design of an ASR for a very low resource language. Finally, similarly to the SVAE/HMM case described above, we found that the degradation of the recall is due to longer units discovered for models with an informative prior (numbers omitted due to lack of space).\nWord discovery results are given in Table TABREF21 for the Boundary metric BIBREF20 , BIBREF21 . We observe that i) the best word boundary detection (F-score) is obtained with MBN features, an informative prior and the SVAE model; this confirms the results of table TABREF23 and shows that better AUD leads to better word segmentation ii) word segmentation from AUD graph Lattices is slightly better than from flat sequences of AUD symbols (1-best); iii) our results outperform a pure speech based baseline based on segmental DTW BIBREF22 (F-score of 19.3% on the exact same corpus).\nIndeed, this suggests that even speech from an unrelated language can be of some help in the design of an ASR for a very low resource language.",

        "evidence": "An airfield traffic pattern is a standard path followed by aircraft when taking off or landing while maintaining visual contact with the airfield.\n\nAt an airport, the pattern (or circuit) is a standard path for coordinating air traffic. It differs from \"straight-in approaches\" and \"direct climb-outs\" in that aircraft using a traffic pattern remain close to the airport. Patterns are usually employed at small general aviation (GA) airfields and military airbases. Many large controlled airports avoid the system unless there is GA activity as well as commercial flights. However, some kind of a pattern may be used at airports in some cases such as when an aircraft is required to go around, but this kind of pattern at controlled airports may be very different in form, shape, and purpose to the standard traffic pattern as used at GA airports.\n\nThe use of a pattern at airfields is for aviation safety. By using a consistent flight pattern, pilots will know from where to expect other air traffic and be able to see and avoid it. Pilots flying under visual flight rules (VFR) may not be separated by air traffic control, so this consistent predictable pattern is a vital way to keep things orderly. At tower-controlled airports, air traffic control (ATC) may provide traffic advisories for VFR flights on a work-load permitting basis.",
        "answer": "Piloting into a non-towered airport in my experience can be more challenging than towered airports.  What makes it challenging is that you are not speaking to anyone in charge of the airspace.  You are broadcasting to an open communications channel and hope all the other pilots “play” by the rules.  The first best practice is to have a basic understanding of the airport, how many runways, what direction do they run, direction of the traffic pattern and traffic pattern altitude etc.?   Practice consistency as this will aid in your decision making process.  As you approach the airport you must also check the weather via AWOS or ASOS to determine the wind direction, speed and altimeter setting.  The next step is to tune into airport UNICOM to listen to other traffic in the area, note the departures and arrivals and also note other planes in the traffic pattern.  The next step is to identify yourself via the airport UNICOM channel, provide your distance to the airport and your direction from the airport.   Your approach direction will most likely determine how and where you will join the traffic pattern.  Most importantly, keep listening to the airport UNICOM and actively look for any other planes either in the traffic pattern or in the vicinity.  There are a minimum of 4 traffic pattern legs - crosswind, downwind, base and final.  Your job as a pilot is to communicate as you enter each pattern leg. It is also beneficial to communicate your intentions whether you are executing a full stop landing or a touch-n-go.  If you are doing a full-stop landing be sure to communicate when you are clear of the given runway.",

In this section, we first describe our problem setup and key terminologies by discussing the dataset used. Later, we formalize our problem definition.\nDataset: For our explorations, we use the Craigslist Bargaining dataset (CB) introduced by BIBREF4. Instead of focusing on the previously studied game environments BIBREF5, BIBREF6, the dataset considers a more realistic setup: negotiating the price of products listed on Craigslist. The dataset consists of 6682 dialogues between a buyer and a seller who converse in natural language to negotiate the price of a given product (sample in Table TABREF1). In total, 1402 product ad postings were scraped from Craigslist, belonging to six categories: phones, bikes, housing, furniture, car and electronics. Each ad posting contains details such as Product Title, Category Type and a Listing Price. Moreover, a secret target price is also pre-decided for the buyer. The final price after the agreement is called the Agreed Price, which we aim to predict.\nDefining the problem: Say we are provided with a product scenario $S$, a tuple: (Category, Title, Listing Price, Target Price). Define the interactions between a buyer and seller using a sequence of $n$ events $E_n:<e_{1}, e_{2}, ..., e_{n}>$, where $e_{i}$ occurs before $e_{j}$ iff $i<j$. Event $e_{i}$ is also a tuple: (Initiator, Type, Data). Initiator is either the Buyer or Seller, Type can be one of (message, offer, accept, reject or quit) and Data consists of either the corresponding natural language dialogue, offer price or can be empty. Nearly $80\\%$ of events in CB dataset are of type `message', each consisting a textual message as Data. An offer is usually made and accepted at the end of each negotiation. Since the offers directly contain the agreed price (which we want to predict), we only consider `message' events in our models. Given the scenario $S$ and first $n$ events $E_n$, our problem is then to learn the function $f_{n}$: $A = f_{n}(S, E_n)$ where $A$ refers to the final agreed price between the two negotiating parties.\n\nSince the offers directly contain the agreed price (which we want to predict), we only consider ‘message’ events in our models.",

While this method allows for customizing the model to the particulars of each language and the available data, it also presents a problem when little data is available: extensive language-specific annotation is required. The reality is that most languages have very little annotated data for most NLP tasks.\nammar2016malopa found that using training data from multiple languages annotated with Universal Dependencies BIBREF1 , and represented using multilingual word vectors, outperformed monolingual training. Inspired by this, we apply the idea of training one model on multiple languages—which we call polyglot training—to PropBank-style semantic role labeling (SRL). We train several parsers for each language in the CoNLL 2009 dataset BIBREF0 : a traditional monolingual version, and variants which additionally incorporate supervision from English portion of the dataset. To our knowledge, this is the first multilingual SRL approach to combine supervision from several languages.\nThe CoNLL 2009 dataset includes seven different languages, allowing study of trends across the same. Unlike the Universal Dependencies dataset, however, the semantic label spaces are entirely language-specific, making our task more challenging. Nonetheless, the success of polyglot training in this setting demonstrates that sharing of statistical strength across languages does not depend on explicit alignment in annotation conventions, and can be done simply through parameter sharing. We show that polyglot training can result in better labeling accuracy than a monolingual parser, especially for low-resource languages. We find that even a simple combination of data is as effective as more complex kinds of polyglot training. We include a breakdown into label categories of the differences between the monolingual and polyglot models. Our findings indicate that polyglot training consistently improves label accuracy for common labels.\nWe train several parsers for each language in the CoNLL 2009 dataset: a traditional monolingual version, and variants which additionally incorporate supervision from English portion of the dataset.

        "evidence": "Text simplification aims to reduce the lexical and structural complexity of a text, while still retaining the semantic meaning, which can help children, non-native speakers, and people with cognitive disabilities, to understand text better. One of the methods of automatic text simplification can be generally divided into three categories: lexical simplification (LS) BIBREF0 , BIBREF1 , rule-based BIBREF2 , and machine translation (MT) BIBREF3 , BIBREF4 . LS is mainly used to simplify text by substituting infrequent and difficult words with frequent and easier words. However, there are several challenges for the LS approach: a great number of transformation rules are required for reasonable coverage and should be applied based on the specific context; third, the syntax and semantic meaning of the sentence is hard to retain. Rule-based approaches use hand-crafted rules for lexical and syntactic simplification, for example, substituting difficult words in a predefined vocabulary. However, such approaches need a lot of human-involvement to manually define these rules, and it is impossible to give all possible simplification rules. MT-based approach has attracted great attention in the last several years, which addresses text simplification as a monolingual machine translation problem translating from 'ordinary' and 'simplified' sentences.\nIn recent years, neural Machine Translation (NMT) is a newly-proposed deep learning approach and achieves very impressive results BIBREF5 , BIBREF6 , BIBREF7 . Unlike the traditional phrased-based machine translation system which operates on small components separately, NMT system is being trained end-to-end, without the need to have external decoders, language models or phrase tables. Therefore, the existing architectures in NMT are used for text simplification BIBREF8 , BIBREF4 . However, most recent work using NMT is limited to the training data that are scarce and expensive to build. Language models trained on simplified corpora have played a central role in statistical text simplification BIBREF9 , BIBREF10 . One main reason is the amount of available simplified corpora typically far exceeds the amount of parallel data. The performance of models can be typically improved when trained on more data. Therefore, we expect simplified corpora to be especially helpful for NMT models.\nIn contrast to previous work, which uses the existing NMT models, we explore strategy to include simplified training corpora in the training process without changing the neural network architecture. We first propose to pair simplified training sentences with synthetic ordinary sentences during training, and treat this synthetic data as additional training data. We obtain synthetic ordinary sentences through back-translation, i.e. an automatic translation of the simplified sentence into the ordinary sentence BIBREF11 . Then, we mix the synthetic data into the original (simplified-ordinary) data to train NMT model. Experimental results on two publicly available datasets show that we can improve the text simplification quality of NMT models by mixing simplified sentences into the training set over NMT model only using the original training data.\nUnlike the traditional phrased-based machine translation system which operates on small components separately, NMT system is being trained end-to end, without the need to have external decoders, language models or phrase tables.",

        "evidence": "Neural Machine Translation (NMT) has shown its effectiveness in translation tasks when NMT systems perform best in recent machine translation campaigns BIBREF0 , BIBREF1 . Compared to phrase-based Statistical Machine Translation (SMT) which is basically an ensemble of different features trained and tuned separately, NMT directly modeling the translation relationship between source and target sentences. Unlike SMT, NMT does not require much linguistic information and large monolingual data to achieve good performances.\nAn NMT consists of an encoder which recursively reads and represents the whole source sentence into a context vector and a recurrent decoder which takes the context vector and its previous state to predict the next target word. It is then trained in an end-to-end fashion to learn parameters which maximizes the likelihood between the outputs and the references. Recently, attention-based NMT has been featured in most state-of-the-art systems. First introduced by BIBREF2 , attention mechanism is integrated in decoder side as feedforward layers. It allows the NMT to decide which source words should take part in the predicting process of the next target words. It helps to improve NMTs significantly. Nevertheless, since the attention mechanism is specific to a particular source sentence and the considering target word, it is also specific to particular language pairs.\nSome recent work has focused on extending the NMT framework to multilingual scenarios. By training such network using parallel corpora in number of different languages, NMT could benefit from additional information embedded in a common semantic space across languages. Basically, the proposed NMT are required to employ multiple encoders or multiple decoders to deal with multilinguality. Furthermore, in order to avoid the tight dependency of the attention mechanism to specific language pairs, they also need to modify their architecture to combine either the encoders or the attention layers. These modifications are specific to the purpose of the tasks as well. Thus, those multilingual NMTs are more complicated, much more free parameters to learn and more difficult to perform standard trainings compared to the original NMT.\nIn this paper, we introduce a unified approach to seamlessly extend the original NMT to multilingual settings. Our approach allows us to integrate any language in any side of the encoder-decoder architecture with only one encoder and one decoder for all the languages involved. Moreover, it is not necessary to do any network modification to enable attention mechanism in our NMT systems. We then apply our proprosed framework in two demanding scenarios: under-resourced translation and zero-resourced translation. The results show that bringing multilinguality to NMT helps to improve individual translations. With some insightful analyses of the results, we set our goal toward a fully multilingual NMT framework.\nThe paper starts with a detailed introduction to attention-based NMT. In Section SECREF3 , related work about multi-task NMT is reviewed. Section SECREF5 describes our proposed approach and thorough comparisons to the related work. It is followed by a section of evaluating our systems in two aforementioned scenarios, in which different strategies have been employed under a unified approach (Section SECREF4 ).

Therefore, in this paper, we conduct a study and aim to understand the characteristics of the encoder and the decoder in NMT. We observe some interesting phenomena:\nThe decoder handles an easier task than the encoder. 1) We find that adding more layers to the encoder achieves larger improvements than adding more layers to the decoder. 2) We also compare the training time of the encoder and decoder by fixing the parameters of a well-trained decoder (encoder), and just update the parameters of the encoder (decoder). We found that the decoder converges faster than the encoder. These two results suggest that the decoder handles an easier task than the encoder in NMT.\nThe decoder is more sensitive to the input noise than the encoder. We randomly add different level of noise to the input of the encoder and decoder respectively during inference, and find that adding noise to the input of the decoder leads to better accuracy drop than that of the encoder.\nWe further analyze why the decoder is more sensitive by masking the previous tokens, and comparing autoregressive NMT with the non-autoregressive counterpart. We find that the preceding tokens in the decoder provide strong conditional information, which partially explain the previous two observations on the decoder.\nWe believe our studies on the different characteristics of the encoder and decoder will inspire the following research on the encoder-decoder framework as well as improve the performance on NMT and other encoder-decoder based tasks.\nWe believe our studies on the different characteristics of the encoder and decoder will inspire the following research on the encoder-decoder framework as well as improve the performance on NMT and other encoder-decoder based tasks.",

The shallow discourse parsing is very useful in the text summariza-tion BIBREF0 , opinion analysis BIBREF1 and natural language generation. Shallow discourse parser is the system of parsing raw text into a set of discourse relations between two adjacent or non-adjacent text spans. Discourse relation is composed of a discourse connective, two arguments of the discourse connective and the sense of the discourse connective. Discourse connective signals the explicit dis-course relation, but in non-explicit discourse relation, a discourse connective is omit-ted. Two arguments of the discourse connective, Arg1 and Arg2, which are the two adjacent or non-adjacent text spans connecting in the discourse relation. The sense of the discourse connective characterizes the nature of the discourse relations. The following discourse relation annotation is taken from the document in the PDTB. Arg1 is shown in italicized, and Arg2 is shown in bold. The discourse connective is underlined.\nThe connective identifier finds the connective word, “unless”. The arguments identifier locates the two arguments of “unless”. The sense classifier labels the dis-course relation. The non-explicit identifier checks all the pair of adjacent sentences. If the non-explicit identifier indentifies the pair of sentences as non-explicit relation, it will label it the relation sense. Though many research work BIBREF2 , BIBREF3 , BIBREF4 are committed to the shallow discourse parsing field, all of them are focus on the subtask of parsing only rather than the whole parsing process. Given all that, a full shallow discourse parser framework is proposed in our paper to turn the free text into discourse relations set. The parser includes connective identifier, arguments identifier, sense classifier and non-explicit identifier, which connects with each other in pipeline. In order to enhance the performance of the parser, the feature-based maximum entropy model approach is adopted in the experiment. Maximum entropy model offers a clean way to combine diverse pieces of contextual evidence in order to estimate the probability of a certain linguistic class occurring with a certain linguistic context in a simple and accessible manner.

Prior to the 1994 strike, the National League champion received home-field advantage in even-numbered years and the American League champion in odd-numbered years; these were reversed for 1995–2002 (because 1994 would have been the NL's turn to have home-field, but the World Series was canceled by the aforementioned strike). That changed starting in 2003.\n\nThe 2002 All-Star Game ended in a tie, much to the displeasure of both fans and sportswriters, who complained about a lack of intensity and competitiveness on the part of the players. This hit especially close to home for Commissioner Bud Selig, as the game had been played in his home city of Milwaukee, Wisconsin. In response, to make the game's outcome more meaningful, in 2003, MLB began assigning home-field advantage in the World Series to the winner of that year's All-Star Game, which is typically held in mid-July.\n\nFollowing the acceptance of a new collective bargaining agreement after the 2016 season (which went into effect in 2017) home-field advantage in the World Series is no longer tied to the outcome of the All-Star Game, but instead is granted to the team with the better regular-season record. One exception was 2020, when all World Series games were played at a neutral site. The home-field advantage designation in the World Series was determined based on whichever pennant winner held the higher seed in its league, not necessarily the team with the better regular season record. However, in the event both pennant winners had held the same seeding number, only then regular season records would have determined the home team in Games 1, 2, 6, and 7.",
        "answer": "Home field advantage for the World Series has been determined in the following ways throughout history:\n- 1924 - 2002: Home field advantage simply alternated between the American and National Leagues each year.\n- 2002 - 2016: Home field advantage was determined by the winner of the All-Star game.\n- 2016 - Present: Home field advantage is determined by the team with the best record playing in the World Series.",

        "question": "What is the difference between the FraCaS test suite and the RTE challenges?",
        "answer": "In contrast to the FraCaS test suite, the RTE challenges use naturally occurring data as premises.",
        "evidence": "The Recognizing Textual Entailment (RTE) challenges first appeared in 2004 as a means to test textual entailment, i.e. relations between a premise text and a hypothesis text ( \"Recognizing Textual Entailment\" ):\nAn entailment example from RTE1.\nBudapest again became the focus of national political drama in the late 1980s, when Hungary led the reform movement in eastern Europe that broke the communist monopoly on political power and ushered in the possibility of multiparty politics.\nIn the late 1980s Budapest became the center of the reform movement.\nEntailment [RTE702]\nIn contrast to the FraCaS test suite, the RTE challenges use naturally occurring data as premises. The hypothesis text is then constructed based on this premise text. There is either a binary or a tripartite classification of entailment — depending on the version of RTE. The first two RTE challenges follow the former scheme and make a binary classification of entailment (entailed or not entailed). Tripartite classification (entailment, negation of the hypothesis entailment or no entailment) is added in the later datasets, retaining two way classification versions as well. Seven RTE challenges have been created altogether.\nThe main advantages of the RTE challenges is their use of examples from natural text and the inclusion of cases that require presupposed information, mostly world knowledge. Indeed, the very definition of inference assumed in a number of the examples is problematic. As BIBREF1 have pointed out, RTE platforms suffer from cases of inference that should not be categorized as such. For these cases, a vast amount of world knowledge needs to be taken into consideration (that most importantly not every linguistic agent has). In this paper, and having the RTE as our starting point challenges, we claim that RTE is insufficiently precise to perform logical reasoning or precise reasoning tasks and we take up the task of validating our working hypothesis and proposing a method for doing proper collection of precise entailment pairs in the style of RTE. Of course, the creators of RTE had in mind a more loose definition of inference where both a precise and an imprecise definition of entailment would be at play. BIBREF2 mention that “our applied notion of textual entailment is also related, of course, to classical semantic entailment in the linguistics literature... a common definition of entailment specifies that a text t entails another text h (hypothesis, in our terminology) if h is true in every circumstance (possible world) in which t is true.\" This is close to what we want to capture in this paper. But, at the same time, BIBREF2 also mention that “however, our applied definition allows for cases in which the truth of the hypothesis is highly plausible, for most practical purposes, rather than certain\". It is these cases we want to make more precise, in the sense of making the supporting hidden inferences that are at play in many of the RTE examples explicit. In a way, what we are aiming at is a methodology of constructing entailment datasets in the style of RTE, that will involve a more precise definition of entailment and will further record any missing/hidden premises are used in justifying or not an entailment pattern.\nIn contrast to the FraCaS test suite, the RTE challenges use naturally occurring data as premises.",

        "question": "What framework do Hausknecht's team introduce to facilitate text-adventure game playing?",
        "answer": "Jericho.",
        "evidence": "Many reinforcement learning algorithms are designed for relatively small discrete or continuous action spaces and so have trouble scaling. Text-adventure games—or interaction fictions—are simulations in which both an agents' state and action spaces are in textual natural language. An example of a one turn agent interaction in the popular text-game Zork1 can be seen in Fig. FIGREF1. Text-adventure games provide us with multiple challenges in the form of partial observability, commonsense reasoning, and a combinatorially-sized state-action space. Text-adventure games are structured as long puzzles or quests, interspersed with bottlenecks. The quests can usually be completed through multiple branching paths. However, games can also feature one or more bottlenecks. Bottlenecks are areas that an agent must pass through in order to progress to the next section of the game regardless of what path the agent has taken to complete that section of the quest BIBREF0. In this work, we focus on more effectively exploring this space and surpassing these bottlenecks—building on prior work that focuses on tackling the other problems.\nFormally, we use the definition of text-adventure games as seen in BIBREF1 and BIBREF2. These games are partially observable Markov decision processes (POMDPs), represented as a 7-tuple of $\\langle S,T,A,\\Omega , O,R, \\gamma \\rangle $ representing the set of environment states, mostly deterministic conditional transition probabilities between states, the vocabulary or words used to compose text commands, observations returned by the game, observation conditional probabilities, reward function, and the discount factor respectively. For our purposes, understanding the exact state and action spaces we use in this work is critical and so we define each of these in relative depth.\nAction-Space. To solve Zork1, the cannonical text-adventure games, requires the generation of actions consisting of up to five-words from a relatively modest vocabulary of 697 words recognized by the game’s parser. This results in $\\mathcal {O}(697^5)={1.64e14}$ possible actions at every step. To facilitate text-adventure game playing, BIBREF2 introduce Jericho, a framework for interacting with text-games. They propose a template-based action space in which the agent first selects a template, consisting of an action verb and preposition, and then filling that in with relevant entities $($e.g. $[get]$ $ [from] $ $)$. Zork1 has 237 templates, each with up to two blanks, yielding a template-action space of size $\\mathcal {O}(237 \\times 697^2)={1.15e8}$. This space is still far larger than most used by previous approaches applying reinforcement learning to text-based games.\nState-Representation. Prior work has shown that knowledge graphs are effective in terms of dealing with the challenges of partial observability $($BIBREF3 BIBREF3; BIBREF4$)$. A knowledge graph is a set of 3-tuples of the form $\\langle subject, relation, object \\rangle $. These triples are extracted from the observations using Stanford's Open Information Extraction (OpenIE) BIBREF5. Human-made text-adventure games often contain relatively complex semi-structured information that OpenIE is not designed to parse and so they add additional rules to ensure that the correct information is parsed. The graph itself is more or less a map of the world, with information about objects' affordances and attributes linked to the rooms that they are place in a map. The graph also makes a distinction with respect to items that are in the agent's possession or in their immediate surrounding environment. An example of what the knowledge graph looks like and specific implementation details can be found in Appendix SECREF14.\nBIBREF6 introduce the KG-A2C, which uses a knowledge graph based state-representation to aid in the section of actions in a combinatorially-sized action-space—specifically they use the knowledge graph to constrain the kinds of entities that can be filled in the blanks in the template action-space. They test their approach on Zork1, showing the combination of the knowledge graph and template action selection resulted in improvements over existing methods. They note that their approach reaches a score of 40 which corresponds to a bottleneck in Zork1 where the player is eaten by a “grue” (resulting in negative reward) if the player has not first lit a lamp. The lamp must be lit many steps after first being encountered, in a different section of the game; this action is necessary to continue exploring but doesn’t immediately produce any positive reward. That is, there is a long term dependency between actions that is not immediately rewarded, as seen in Figure FIGREF1. Others using artificially constrained action spaces also report an inability to pass through this bottleneck BIBREF7, BIBREF8. They pose a significant challenge for these methods because the agent does not see the correct action sequence to pass the bottleneck enough times. This is in part due to the fact that for that sequence to be reinforced, the agent needs to reach the next possible reward beyond the bottleneck.\nMore efficient exploration strategies are required to pass bottlenecks. Our contributions are two-fold. We first introduce a method that detects bottlenecks in text-games using the overall reward gained and the knowledge graph state. This method freezes the policy used to reach the bottleneck and restarts the training from there on out, additionally conducting a backtracking search to ensure that a sub-optimal policy has not been frozen. The second contribution explore how to leverage knowledge graphs to improve existing exploration algorithms for dealing with combinatorial action-spaces such as Go-Explore BIBREF9. We additionally present a comparative ablation study analyzing the performance of these methods on the popular text-game Zork1.\nTo facilitate text-adventure game playing, Hausknecht et al.

        "question": "Does their method outperform existing state-of-the-art models?",
        "answer": "Yes.",
        "evidence": "Since the advent of large structured knowledge bases (KBs) like Freebase BIBREF0 , YAGO BIBREF1 and DBpedia BIBREF2 , answering natural language questions using those structured KBs, also known as KB-based question answering (or KB-QA), is attracting increasing research efforts from both natural language processing and information retrieval communities.\nThe state-of-the-art methods for this task can be roughly categorized into two streams. The first is based on semantic parsing BIBREF3 , BIBREF4 , which typically learns a grammar that can parse natural language to a sophisticated meaning representation language. But such sophistication requires a lot of annotated training examples that contains compositional structures, a practically impossible solution for large KBs such as Freebase. Furthermore, mismatches between grammar predicted structures and KB structure is also a common problem BIBREF4 , BIBREF5 , BIBREF6 .\nOn the other hand, instead of building a formal meaning representation, information extraction methods retrieve a set of candidate answers from KB using relation extraction BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 or distributed representations BIBREF11 , BIBREF12 . Designing large training datasets for these methods is relatively easy BIBREF7 , BIBREF13 , BIBREF14 . These methods are often good at producing an answer irrespective of their correctness. However, handling compositional questions that involve multiple entities and relations, still remains a challenge. Consider the question what mountain is the highest in north america. Relation extraction methods typically answer with all the mountains in North America because of the lack of sophisticated representation for the mathematical function highest. To select the correct answer, one has to retrieve all the heights of the mountains, and sort them in descending order, and then pick the first entry. We propose a method based on textual evidence which can answer such questions without solving the mathematic functions implicitly.\nKnowledge bases like Freebase capture real world facts, and Web resources like Wikipedia provide a large repository of sentences that validate or support these facts. For example, a sentence in Wikipedia says, Denali (also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. To answer our example question against a KB using a relation extractor, we can use this sentence as external evidence, filter out wrong answers and pick the correct one.\nUsing textual evidence not only mitigates representational issues in relation extraction, but also alleviates the data scarcity problem to some extent. Consider the question, who was queen isabella's mother. Answering this question involves predicting two constraints hidden in the word mother. One constraint is that the answer should be the parent of Isabella, and the other is that the answer's gender is female. Such words with multiple latent constraints have been a pain-in-the-neck for both semantic parsing and relation extraction, and requires larger training data (this phenomenon is coined as sub-lexical compositionality by wang2015). Most systems are good at triggering the parent constraint, but fail on the other, i.e., the answer entity should be female. Whereas the textual evidence from Wikipedia, ...her mother was Isabella of Barcelos ..., can act as a further constraint to answer the question correctly.\nWe present a novel method for question answering which infers on both structured and unstructured resources. Our method consists of two main steps as outlined in sec:overview. In the first step we extract answers for a given question using a structured KB (here Freebase) by jointly performing entity linking and relation extraction (sec:kb-qa). In the next step we validate these answers using an unstructured resource (here Wikipedia) to prune out the wrong answers and select the correct ones (sec:refine). Our evaluation results on a benchmark dataset WebQuestions show that our method outperforms existing state-of-the-art models. Details of our experimental setup and results are presented in sec:experiments. Our code, data and results can be downloaded from https://github.com/syxu828/QuestionAnsweringOverFB.\nOur evaluation results on a benchmark dataset WebQuestions show that our method outperforms existing state-of-the-art models.",

As of September 2018, the 13 member countries accounted for an estimated 44 percent of global oil production and 81.5 percent of the world's proven oil reserves, giving OPEC a major influence on global oil prices that were previously determined by the so-called \"Seven Sisters\" grouping of multinational oil companies.\n\nThe formation of OPEC marked a turning point toward national sovereignty over natural resources, and OPEC decisions have come to play a prominent role in the global oil market and international relations. The effect can be particularly strong when wars or civil disorders lead to extended interruptions in supply. In the 1970s, restrictions in oil production led to a dramatic rise in oil prices and in the revenue and wealth of OPEC, with long-lasting and far-reaching consequences for the global economy. In the 1980s, OPEC began setting production targets for its member nations; generally, when the targets are reduced, oil prices increase. This has occurred most recently from the organization's 2008 and 2016 decisions to trim oversupply.",

Then the sequence-to-sequence model trained in a single language can be directly evaluated beyond that language (i.e., accepting multi-lingual input and producing multi-lingual output). Experimental results on question generation and abstractive summarization show that our model outperforms the machine-translation-based pipeline methods for zero-shot cross-lingual generation.

However, GNNs have only recently started to be closely investigated, following the advent of deep learning. Some notable examples include BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12. These approaches are known as spectral. Their similarity with message passing (MP) was observed by BIBREF9 and formalized by BIBREF13 and BIBREF14.\nThe MP framework is based on the core idea of recursive neighborhood aggregation. That is, at every iteration, the representation of each vertex is updated based on messages received from its neighbors. All spectral GNNs can be described in terms of the MP framework.\nGNNs have been applied with great success to bioinformatics and social network data, for node classification, link prediction, and graph classification. However, a few studies only have focused on the application of the MP framework to representation learning on text. This paper proposes one such application. More precisely, we represent documents as word co-occurrence networks, and develop an expressive MP GNN tailored to document understanding, the Message Passing Attention network for Document understanding (MPAD). We also propose several hierarchical variants of MPAD. Evaluation on 10 document classification datasets show that our architectures learn representations that are competitive with the state-of-the-art. Furthermore, ablation experiments shed light on the impact of various architectural choices.\nIn what follows, we first provide some background about the MP framework (in sec. SECREF2), thoroughly describe and explain MPAD (sec. SECREF3), present our experimental framework (sec. SECREF4), report and interpret our results (sec.

Piotr Stefan Wandycz wrote that the \"liberum veto had become the sinister symbol of old Polish anarchy\".

        "question": "Based on the information provided, what was the controversy surrounding the 2021 Abu Dhabi Grand Prix?",
        "evidence": "The 2021 Abu Dhabi Grand Prix (officially known as the Formula 1 Etihad Airways Abu Dhabi Grand Prix 2021) was a Formula One motor race held on 12 December 2021 at the Yas Marina Circuit in Abu Dhabi, United Arab Emirates. Contested over a distance of 58 laps, the race was the twenty-second and final round of the 2021 Formula One World Championship. The race decided both the Drivers' and Constructors' championships; Max Verstappen and Lewis Hamilton both had 369.5 points coming into the race. Hamilton led most of the race and appeared on course to win what would have been a record eighth World Drivers' Championship, having taken the lead at the start of the race at turn 1 on the first lap. However Verstappen was the eventual winner, overtaking Hamilton on the final lap after a controversial safety car restart in the last moments of the race. The FIA thus conducted an inquiry into the race which led to a restructuring of race control including the replacement of Michael Masi as race director and amendments to the safety car rules. That inquiry subsequently concluded that the race officials had misapplied the then-regulations due to human error, but confirmed the results.\n\nVerstappen's win secured his first Formula One World Drivers' Championship of his career by eight points from Hamilton, and Red Bull Racing's first since 2013. Mercedes won their eighth consecutive Formula One World Constructors' Championship, setting a new record. The Grand Prix was also the final race for 2007 World Champion Kimi Räikkönen; the 42-year-old Finn retired from Formula One after a two-decade career spanning 349 Grands Prix starts.\n\nRace\n\nStart and opening laps\nThe race started at 17:00 local time on Sunday 12 December. Lewis Hamilton immediately took the lead from Max Verstappen on the race start, prompting Verstappen to attempt to regain his position at the turn 6 chicane. Verstappen's trajectory forced Hamilton off the track, and the Briton re-entered slightly further ahead of the Dutch driver than he was before the corner. Arguing that he should have ceded the position to Verstappen, Red Bull Racing protested the racing line taken by Hamilton, and were told by radio that Hamilton had ultimately given back any advantage gained. The incident was referred to the stewards, which concluded that no further investigation was necessary. Hamilton then utilised the durability of his medium-compound tyres to extend his lead over Verstappen, whose soft-compound tyres were suffering from greater degradation.\n\nPit-stops and virtual safety car\nVerstappen made his stop at the end of lap 13 with Hamilton following suit one lap later, both opting for a set of the hardest tyres. The lead drivers pitting elevated Sergio Pérez to first, with the Mexican driver being informed his strategy was to hold up Hamilton to allow his teammate Verstappen to catch up. Hamilton caught up with Pérez on lap 20; a spirited defence from the Red Bull second driver allowed Verstappen to significantly close the gap from about 11 seconds after the pits to 1.3 second. Verstappen was unable to take advantage of it, with Hamilton's superior pace extending the gap to four seconds by the midpoint of the race.\n\nFinal laps\nOn lap 53, a crash at turn 14 for Nicholas Latifi, who was fighting for position with Haas' Mick Schumacher and had dirty tyres after going off circuit at turn 9, brought out the safety car. Hamilton again stayed out without pitting because he would have lost track position had the safety car period not ended, while Verstappen pitted behind him for a fresh set of the softest available tyres. Pérez retired under the safety car due to oil pressure. After Verstappen's pit stop, he retained second, but with five lapped cars (those of Lando Norris, Fernando Alonso, Esteban Ocon, Charles Leclerc, and Sebastian Vettel) between himself and Hamilton (in first). As the debris from Latifi's crash was being cleared by the race marshals, the lapped drivers were initially informed that they would not be permitted to overtake. On lap 57 Masi gave the direction that only the five cars between Hamilton and Verstappen were to unlap themselves.\n\nImmediately after Vettel passed the safety car to join the lead lap, race control announced the safety car would enter the pits at the end of the lap to allow for a final lap of green-flag racing, leading to angry remonstrations from Mercedes team principal Toto Wolff. On the final lap, Verstappen used his fresh soft tyres to pass Hamilton into turn 5 to take the lead of the race. He held off counter-attacks from Hamilton to win the race and his first World Drivers' Championship, with Hamilton in second and Ferrari driver Carlos Sainz Jr. in third. AlphaTauri driver Yuki Tsunoda finished in a career-best fourth place, after overtaking Bottas. Mercedes gained enough points to win their eighth consecutive Constructors' title, extending their own record. Over the radio, Wolff appealed to Masi to reinstate the order of the penultimate lap, to which Masi gave the reply: \"Toto, it's called a motor race, ok? We went car racing.\"\n\nSafety car controversy\nMichael Masi was involved in a safety car procedure controversy during the last laps of the race. On lap 56 of the race, during which Hamilton was leading, Masi allowed only the five cars directly in between championship contenders Hamilton and Verstappen to unlap themselves before the restart. The race restarted, and on the final lap of the race, Verstappen overtook Hamilton and won the 2021 World Drivers' Championship.\n\nMercedes' post-race protests\nMercedes protested the race result, alleging that Verstappen had overtaken Hamilton during the safety car and that Masi violated safety car procedure by allowing the cars directly in front of Verstappen to unlap themselves, and no others, and that according to regulations the restart should have occurred the following lap, which would have resulted in Hamilton's victory. While the first issue was dismissed because Verstappen was not ahead at the end of the safety car period, the second issue was more contentious, with Mercedes retaining legal counsel for the protest. Mercedes argued that if a message for lapped cars to overtake is issued under Article 48.12, then all lapped cars are required to unlap, and that the safety car was required to wait until the end of the following lap to return to the pit lane; if this process was complied with, Mercedes submitted that Hamilton would have won the race and therefore the championship, and requested that the classification be amended as such. Red Bull argued that a) the regulation stated \"any cars\", not \"all cars\", were required to overtake under Articles 48.12; b) 48.13, which governs the withdrawal of the safety car, overrides Article 48.12; c) Article 15.3 gives the race director overriding authority over the use of the safety car; and d) the race result would not have changed if all eight lapped cars were permitted to unlap. Masi argued that the principle behind Article 48.12 was to remove cars which \"interfered\" with drivers racing on the lead lap and that all teams had agreed in principle that all races should end under racing conditions.\n\nThe clerk of the course shall work in permanent consultation with the Race Director. The Race Director shall have overriding authority in the following matters and the clerk of the course may give orders in respect of them only with his express agreement: ... e) The use of the safety car.\n\n\nMercedes lodged their intentions to appeal the ruling. Following the FIA's announcement that it would conduct a \"detailed analysis and clarification exercise\" of the incident and its admission that the controversy was \"tarnishing the image\" of the sport, Mercedes decided not to pursue their appeal, and announced the discontinuation of their protest on 16 December, several hours before the submission deadline. Amongst the reasons to discontinue, Wolff said that neither he nor Hamilton wished to be awarded the drivers' championship in court, and instead would focus their efforts in to ensuring an equitable result from the FIA's investigation into the sporting code. Wolff remained heavily critical of Masi's direction of the race—in particular, Wolff criticised Masi's decision in Abu Dhabi as being inconsistent with a decision at the 2020 Eifel Grand Prix, where Masi cited the need to let all cars unlap to extend a safety car period—and both he and Hamilton boycotted the FIA Prize Giving Ceremony that evening. Hamilton was later fined for not attending; he asked the FIA to donate the fine as contribution towards the work the body carries out with underprivileged children. The statement also fuelled speculation that Hamilton could announce a snap retirement after being disillusioned by the race's events, although Wolff indicated both he and his driver would continue in the sport after a period of reflection in the off-season.\n\nRace reactions and commentary\nIn the immediate post-race interview, Hamilton and his father Anthony congratulated Verstappen and his family on his first World Drivers' Championship.\n\nSeveral drivers criticised Masi's decision which was seen as a divergence from standard safety car procedure. In a last-lap radio message to his race engineer Peter Bonnington, that was not played on the television feed, Hamilton said the race result had been \"manipulated\". Russell, who was signed to be Hamilton's teammate at Mercedes in 2022, called the race finishing decision of race director Michael Masi \"unacceptable\". Norris, who was situated at the front of the five cars permitted to unlap, said the decision to go racing again on the last lap was made \"for TV\", and Alonso, Ocon, Leclerc, and Vettel, the drivers of the other four cars in the pack, also expressed confusion at the sudden instruction to unlap. Daniel Ricciardo, who was situated immediately behind Verstappen during the safety car period and was not permitted to unlap himself, said he was \"speechless\" at the instruction, especially as it did not allow him to also race the five-car pack on newer soft-compound tyres, and Sainz Jr., who was positioned behind Ricciardo and Lance Stroll's cars upon the restart and was under pressure from Yuki Tsunoda, Pierre Gasly, and Valtteri Bottas, opined that the decision to resume racing under the circumstances \"nearly cost [him his] podium\". Speaking at Aston Martin's 2022 car launch in February 2022, Lance Stroll described the Abu Dhabi situation as \"ridiculous\" and that rules should be set in stone before a season starts.",
        "answer": "While there was a lot of complexity based on the circumstances that occurred, the prevailing controversy with the race was related to the fact that lapped cars were only partially allowed to clear the track. This meant that Max Verstappen was cleared to attack Lewis Hamilton on fresher tyres for the last part of the final lap. Lewis and Max both needed to win the final race to win the championship. This would have been Max's first ever championship or Lewis' record-breaking 8th championship. By allowing only the cars between Max and Lewis, the race director only partially adhered to the rules. This virtually handed the win to Max and Red Bull. While Mercedes immediately protested the decision and final result. Max was awarded the championship.",

The book is recognized as a classic in children's literature, and is one of the best-selling books of all time with over 100 million copies sold.\n\nThe Hobbit is set in Middle-earth and follows home-loving Bilbo Baggins, the titular hobbit, who joins the wizard Gandalf and thirteen dwarves that make up Thorin Oakenshield's Company, on a quest to reclaim the dwarves' home and treasure from the dragon Smaug. Bilbo's journey takes him from his peaceful rural surroundings into more sinister territory.\n\nThe story is told in the form of an episodic quest, and most chapters introduce a specific creature or type of creature of Tolkien's geography. Bilbo gains a new level of maturity, competence, and wisdom by accepting the disreputable, romantic, fey, and adventurous sides of his nature and applying his wits and common sense. The story reaches its climax in the Battle of Five Armies, where many of the characters and creatures from earlier chapters re-emerge to engage in conflict.\n\nPersonal growth and forms of heroism are central themes of the story, along with motifs of warfare. These themes have led critics to view Tolkien's own experiences during World War I as instrumental in shaping the story. The author's scholarly knowledge of Germanic philology and interest in mythology and fairy tales are often noted as influences.\n\nThe publisher was encouraged by the book's critical and financial success and, therefore, requested a sequel. As Tolkien's work progressed on its successor, The Lord of the Rings, he made retrospective accommodations for it in The Hobbit. These few but significant changes were integrated into the second edition. Further editions followed with minor emendations, including those reflecting Tolkien's changing concept of the world into which Bilbo stumbled.\n\nThe work has never been out of print.

He won election to the New York State Senate in 1910 and then served as Assistant Secretary of the Navy under president Woodrow Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic Party's ticket in the 1920 United States presidential election, but Cox was defeated by Republican Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness that permanently paralyzed his legs. He returned to public office by winning the 1928 New York gubernatorial election. He served as governor of New York from 1929 to 1933, promoting programs to combat the Great Depression besetting the United States at the time. In the 1932 presidential election, Roosevelt defeated Republican incumbent president Herbert Hoover in a landslide.\n\nDuring his first 100 days as president, Roosevelt spearheaded unprecedented federal legislation and issued a profusion of executive orders that instituted the New Deal. He created numerous programs to provide relief to the unemployed and farmers while seeking economic recovery with the National Recovery Administration and other programs. He also instituted major regulatory reforms related to finance, communications, and labor, and presided over the end of Prohibition. In 1936, Roosevelt won a landslide reelection with the economy having improved rapidly from 1933, but the economy relapsed into a deep recession in 1937 and 1938. Later, Roosevelt unsuccessfully sought passage of the Judicial Procedures Reform Bill of 1937. The conservative coalition formed in 1937 to block the implementation of further New Deal programs and reforms. He ran successfully for reelection in 1940, becoming the only American president to serve for more than two terms.\n\nWith World War II looming after 1938 in addition to the Japanese invasion of China and the aggression of Nazi Germany, Roosevelt gave strong diplomatic and financial support to China as well as the United Kingdom and the Soviet Union while the United States remained officially neutral. Following the Japanese attack on Pearl Harbor on December 7, 1941, he obtained a declaration of war on Japan the next day, and a few days later, on Germany and Italy. He worked closely with other national leaders in leading the Allies against the Axis powers. Roosevelt supervised the mobilization of the American economy to support the war effort and implemented a Europe first strategy. He also initiated the development of the world's first atomic bomb and worked with the other Allied leaders to lay the groundwork for the United Nations and other post-war institutions. He won reelection in 1944 but with his physical health seriously and steadily declining during the war years, he died in 1945.

        "question": "How are most models primarily evaluated in NLP and machine learning?",
        "answer": "In NLP and machine learning, most models are primarily evaluated by comparing the machine-generated labels against an annotated sample.",
        "evidence": "The output of our measurement procedures (in the social sciences often called the “scores”) must now be assessed in terms of their reliability and validity with regard to the (systemized) concept. Reliability aims to capture repeatability, i.e. the extent to which a given tool provides consistent results.\nValidity assesses the extent to which a given measurement tool measures what it is supposed to measure. In NLP and machine learning, most models are primarily evaluated by comparing the machine-generated labels against an annotated sample. This approach presumes that the human output is the “gold standard\" against which performance should be tested. In contrast, when the reliability is measured based on the output of different annotators, no coder is taken as the standard and the likelihood of coders reaching agreement by chance (rather than because they are “correct\") is factored into the resulting statistic. Comparing against a “gold standard” suggests that the threshold for human inter- and intra-coder reliability should be particularly high.\nAccuracy, as well as other measures such as precision, recall and F-score, are sometimes presented as a measure of validity, but if we do not have a genuinely objective determination of what something is supposed measure—as is often the case in text analysis—then accuracy is perhaps a better indication of reliability than of validity. In that case, validity needs to be assessed based on other techniques like those we discuss later in this section. It is also worth asking what level of accuracy is sufficient for our analysis and to what extent there may be an upper bound, especially when the labels are native to the data or when the notion of a “gold standard” is not appropriate.\nFor some in the humanities, validation takes the form of close reading, not designed to confirm whether the model output is correct, but to present what BIBREF48 refers to as a form of “further discovery in two directions”. Model outputs tell us something about the texts, while a close reading of the texts alongside those outputs tells us something about the models that can be used for more effective model building. Applying this circular, iterative process to 450 18th-century novels written in three languages, Piper was able to uncover a new form of “conversional novel” that was not previously captured in “literary history's received critical categories” BIBREF48 .\nAlong similar lines, we can subject both the machine-generated output and the human annotations to another round of content validation. That is, take a stratified random sample, selecting observations from the full range of scores, and ask: Do these make sense in light of the systematized concept? If not, what seems to be missing? Or is something extraneous being captured? This is primarily a qualitative process that requires returning to theory and interrogating the systematized concept, indicators, and scores together. This type of validation is rarely done in NLP, but it is especially important when it is difficult to assess what drives a given machine learning model. If there is a mismatch between the scores and systematized concept at this stage, the codebook may need to be adjusted, human coders retrained, more training data prepared, algorithms adjusted, or in some instances, even a new analytical method adopted.\nOther types of validation are also possible, such as comparing with other approaches that aim to capture the same concept, or comparing the output with external measures (e.g., public opinion polls, the occurrence of future events). We can also go beyond only evaluating the labels (or point estimates). BIBREF16 used human judgments to not only assess the positional estimates from a scaling method of latent political traits but also to assess uncertainty intervals. Using different types of validation can increase our confidence in the approach, especially when there is no clear notion of ground truth.\nBesides focusing on rather abstract evaluation measures, we could also assess the models in task-based settings using human experts. Furthermore, for insight-driven analyses, it can be more useful to focus on improving explanatory power than making small improvements in predictive performance.\nIn NLP and machine learning, most models are primarily evaluated by comparing the machine-generated labels against an annotated sample.",

        "evidence": "\"Robert Stinnett's Day of Deceit suggests a memorandum prepared by Commander McCollum was central to U.S. policy in the immediate pre-war period. Stinnett claims the memo suggests only a direct attack on U.S. interests would sway the American public (or Congress) to favor direct involvement in the European war, specifically in support of the British. An attack by Japan would not, could not, aid Britain. Although the memo was passed to Captains Walter Anderson and Dudley Knox, two of Roosevelt's military advisors, on October 7, 1940, there is no evidence to suggest Roosevelt ever saw it, while Stinnett's claims of evidence he did is nonexistent. Moreover, although Anderson and Knox offered eight specific plans to aggrieve the Japanese Empire and added, \"If by these means Japan could be led to commit an overt act of war, so much the better,\" of the eight \"plans\" (actions to be taken) offered in the memo, many if not all were implemented, but there is considerable doubt the McCollum memo was the inspiration.[citation needed] Nonetheless, in Day of Deceit Stinnett claims all action items were implemented. Yet there were numerous instances of members of the Roosevelt Administration insisting on not provoking Japan. Mark Parillo, in his essay The United States in the Pacific, wrote, \"hese theories tend to founder on the logic of the situation. Had Roosevelt and other members of his administration known of the attack in advance, they would have been foolish to sacrifice one of the major instruments needed to win the war just to get the United States into it.\" Furthermore, on 5 November 1941, in a joint memo, Stark, CNO, and Marshall, Army Chief of Staff, warned, \"if Japan be defeated and Germany remain undefeated, decision will still not have been reached.... War between the United States and Japan should be avoided....\" Additionally, in a 21 November 1941 memo, Brigadier Leonard T. Gerow, head of Army War Plans, stated, \"one of our present major objectives  the avoidance of war with Japan...[and to] insure continuance of material assistance to the British.\" He concluded, \"[I]t is of grave importance to our war effort in Europe...\" Furthermore, Churchill himself, in a 15 May 1940 telegram, said he hoped a U.S. commitment to aid Britain would \"quiet\" Japan, following with a 4 October message requesting a USN courtesy visit to Singapore aimed at \"preventing the spreading of the war\" And Stark's own Plan Dog expressly stated, \"Any strength that we might send to the Far East would...reduce the force of our blows against Germany...\" Roosevelt could scarcely have been ignorant of Stark's views, and war with Japan was clearly contrary to Roosevelt's express wish to aid Britain.\"\nhttps://en.wikipedia.org/wiki/Pearl_Harbor_advance-knowledge_conspiracy_theory",
        "answer": "This paragraph summarizes both Robert Stinnett's argument that the US government intentionally provoked the Japanese attack on Pearl Harbor and the counter-arguments. Stinnett's case is based largely on a memo from Commander McCollom stating that the only way to US population and its elected officials could be convinced to enter WWII would be if there was a direct attack on the US. Stinnett argues that the government then did everything recommended in the memo in order to compel the Japanese to attack. According to this paragraph, arguments that disprove Stinnett's claim include the fact that the military would never endanger the fleet in Pearl Harbor needed to win the war in a plan to convince the American people to join the way. In addition, there is compelling evidence that Roosevelt was attempting to minimize the conflict with Japan in order to focus on aid to England.",

We collected more data for later rounds not only because that data is likely to be more interesting, but also simply because the base model is better and so annotation took longer to collect good, verified correct examples of model vulnerabilities.\nFor each round, we report the model error rate, both on verified and unverified examples. The unverified model error rate captures the percentage of examples where the model disagreed with the writer's target label, but where we are not (yet) sure if the example is correct. The verified model error rate is the percentage of model errors from example pairs that other annotators were able to confirm the correct label for. Note that this error rate represents a straightforward way to evaluate model quality: the lower the model error rate—assuming constant annotator quality and context-difficulty—the better the model.\nWe observe that model error rates decrease as we progress through rounds. In Round 3, where we included a more diverse range of contexts from various domains, the overall error rate went slightly up compared to the preceding round, but for Wikipedia contexts the error rate decreased substantially. While for the first round roughly 1 in every 5 examples were verified model errors, this quickly dropped over consecutive rounds, and the overall model error rate is less than 1 in 10. On the one hand, this is impressive, and shows how far we have come with just three rounds. On the other hand, it shows that we still have a long way to go if even untrained annotators can fool ensembles of state-of-the-art models with relative ease.\nTable TABREF7 also reports the average number of “tries”, i.e., attempts made for each context until a model error was found (or the number of possible tries is exceeded), and the average time this took (in seconds).

        "question": "Given this paragraph about Charles Inglis, give answers to the following: his father's name, his colleague's name, and his grandfather's occupation.",
        "evidence": "Charles Inglis was the second son of Dr. Alexander Inglis (a general practitioner in Worcester) and his first wife, Florence, the daughter of newspaper proprietor John Frederick Feeney. His elder brother was the historian John Alexander Inglis FRSE Their father, Alexander Inglis was born in Scotland to a respectable family – his grandfather, John Inglis, was an Admiral in the Royal Navy and had captained HMS Belliqueux at the Battle of Camperdown in 1797.\n\nCharles Inglis was born on 31 July 1875. He was not expected to survive and was hurriedly baptised in his father's drawing room; his mother died from complications eleven days later. His family moved to Cheltenham and Inglis was schooled at Cheltenham College from 1889 to 1894. In his final year, he was elected head boy and received a scholarship to study the Mathematics Tripos at King's College, Cambridge. Inglis was 22nd wrangler[nb 1] when he received his Bachelor of Arts degree in 1897; he remained for a fourth year, achieving first class honours in Mechanical Sciences. Inglis was a keen sportsman and enjoyed long-distance running, walking, mountaineering and sailing. At Cambridge, he nearly achieved a blue for long-distance running but was forced to withdraw from a significant race because of a pulled muscle. He was also a follower of the Cambridge University Rugby Union team, watching their matches at Grange Road.\n\nAfter graduation, Inglis began work as an apprentice for the civil engineering firm of John Wolfe-Barry & Partners. He worked as a draughtsman in the drawing office for several months before being placed with Alexander Gibb, who was acting as resident engineer on an extension to the Metropolitan District Railway between Whitechapel and Bow. Inglis was responsible for the design and supervision of all thirteen bridges on the route. It was during this time that he began his lifelong study of vibration and its effects on materials, particularly bridges.",

The former comes from the scripts of the Friends TV sitcom. The other is made up of Facebook messenger chats. Each subset includes $1,000$ English dialogues, and each dialogue can be further divided into a few consecutive utterances. All the utterances are annotated by five annotators on a crowd-sourcing platform (Amazon Mechanical Turk), and the labeling work is only based on the textual content. Annotator votes for one of the seven emotions, namely Ekman’s six basic emotions BIBREF1, plus the neutral. If none of the emotion gets more than three votes, the utterance will be marked as “non-neutral”.\nFor the datasets, there are properties worth additional mentioning. Although Friends and EmotionPush share the same data format, they are quite different in nature. Friends is a speech-based dataset which is annotated dialogues from the TV sitcom. It means most of the utterances are generated by the a few main characters. The personality of a character often affects the way of speaking, and therefore “who is the speaker\" might provide extra clues for emotion prediction. In contrast, EmotionPush does not have this trait due to the anonymous mechanism. In addition, features such as typo, hyperlink, and emoji that only appear in chat-based data will need some domain-specific techniques to process.\nIncidentally, the objective of the challenge is to predict the emotion for each utterance. Just, according to EmotionX 2019 specification, there are only four emotions be selected as our label candidates, which are Joy, Sadness, Anger, and Neutral. These emotions will be considered during performance evaluation.

        "question": "What model do they compress when running experiments?",
        "answer": "A large state-ofthe-art 4 × 1000 LSTM model.",
        "evidence": "Neural machine translation (NMT) BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 is a deep learning-based method for translation that has recently shown promising results as an alternative to statistical approaches. NMT systems directly model the probability of the next word in the target sentence simply by conditioning a recurrent neural network on the source sentence and previously generated target words.\nWhile both simple and surprisingly accurate, NMT systems typically need to have very high capacity in order to perform well: Sutskever2014 used a 4-layer LSTM with 1000 hidden units per layer (herein INLINEFORM0 ) and Zhou2016 obtained state-of-the-art results on English INLINEFORM1 French with a 16-layer LSTM with 512 units per layer. The sheer size of the models requires cutting-edge hardware for training and makes using the models on standard setups very challenging.\nThis issue of excessively large networks has been observed in several other domains, with much focus on fully-connected and convolutional networks for multi-class classification. Researchers have particularly noted that large networks seem to be necessary for training, but learn redundant representations in the process BIBREF6 . Therefore compressing deep models into smaller networks has been an active area of research. As deep learning systems obtain better results on NLP tasks, compression also becomes an important practical issue with applications such as running deep learning models for speech and translation locally on cell phones.\nExisting compression methods generally fall into two categories: (1) pruning and (2) knowledge distillation. Pruning methods BIBREF7 , BIBREF8 , BIBREF9 , zero-out weights or entire neurons based on an importance criterion: LeCun1990 use (a diagonal approximation to) the Hessian to identify weights whose removal minimally impacts the objective function, while Han2016 remove weights based on thresholding their absolute values. Knowledge distillation approaches BIBREF0 , BIBREF10 , BIBREF1 learn a smaller student network to mimic the original teacher network by minimizing the loss (typically INLINEFORM0 or cross-entropy) between the student and teacher output.\nIn this work, we investigate knowledge distillation in the context of neural machine translation. We note that NMT differs from previous work which has mainly explored non-recurrent models in the multi-class prediction setting. For NMT, while the model is trained on multi-class prediction at the word-level, it is tasked with predicting complete sequence outputs conditioned on previous decisions. With this difference in mind, we experiment with standard knowledge distillation for NMT and also propose two new versions of the approach that attempt to approximately match the sequence-level (as opposed to word-level) distribution of the teacher network. This sequence-level approximation leads to a simple training procedure wherein the student network is trained on a newly generated dataset that is the result of running beam search with the teacher network.\nWe run experiments to compress a large state-of-the-art INLINEFORM0 LSTM model, and find that with sequence-level knowledge distillation we are able to learn a INLINEFORM1 LSTM that roughly matches the performance of the full system. We see similar results compressing a INLINEFORM2 model down to INLINEFORM3 on a smaller data set. Furthermore, we observe that our proposed approach has other benefits, such as not requiring any beam search at test-time. As a result we are able to perform greedy decoding on the INLINEFORM4 model 10 times faster than beam search on the INLINEFORM5 model with comparable performance. Our student models can even be run efficiently on a standard smartphone. Finally, we apply weight pruning on top of the student network to obtain a model that has INLINEFORM6 fewer parameters than the original teacher model. We have released all the code for the models described in this paper.\nWe run experiments to compress a large state-ofthe-art 4 × 1000 LSTM model, and find that with sequence-level knowledge distillation we are able to learn a 2 × 500 LSTM that roughly matches the performance of the full system.",

        "question": "Why is early detection of cyberbullying attempts important to youngsters' mental well-being?",
        "answer": "Because the prevalence of cyberbullying is a serious problem and can lead to dramatic consequences.",
        "evidence": "Web 2.0 has had a substantial impact on communication and relationships in today's society. Children and teenagers go online more frequently, at younger ages, and in more diverse ways (e.g. smartphones, laptops and tablets). Although most of teenagers' Internet use is harmless and the benefits of digital communication are evident, the freedom and anonymity experienced online makes young people vulnerable, with cyberbullying being one of the major threats BIBREF0 , BIBREF1 , BIBREF2 .\nBullying is not a new phenomenon, and cyberbullying has manifested itself as soon as digital technologies have become primary communication tools. On the positive side, social media like blogs, social networking sites (e.g. Facebook) and instant messaging platforms (e.g. WhatsApp) make it possible to communicate with anyone and at any time. Moreover, they are a place where people engage in social interaction, offering the possibility to establish new relationships and maintain existing friendships BIBREF3 , BIBREF4 . On the negative side however, social media increase the risk of children being confronted with threatening situations including grooming or sexually transgressive behaviour, signals of depression and suicidal thoughts, and cyberbullying. Users are reachable 24/7 and are often able to remain anonymous if desired: this makes social media a convenient way for bullies to target their victims outside the school yard.\nWith regard to cyberbullying, a number of national and international initiatives have been launched over the past few years to increase children's online safety. Examples include KiVa, a Finnish cyberbullying prevention programme, the `Non au harcèlement' campaign in France, Belgian governmental initiatives and helplines (e.g. clicksafe.be, veiligonline.be, mediawijs.be) that provide information about online safety, and so on.\nIn spite of these efforts, a lot of undesirable and hurtful content remains online. BIBREF1 analysed a body of quantitative research on cyberbullying and observed cybervictimisation rates among teenagers between 20% and 40%. BIBREF5 focused on 12 to 17 year olds living in the United States and found that no less than 72% of them had encountered cyberbullying at least once within the year preceding the questionnaire. BIBREF6 surveyed 9 to 26 year olds in the United States, Canada, the United Kingdom and Australia, and found that 29% of the respondents had ever been victimised online. A study among 2,000 Flemish secondary school students (age 12 to 18) revealed that 11% of them had been bullied online at least once in the six months preceding the survey BIBREF7 . Finally, the 2014 large-scale EU Kids Online Report BIBREF8 published that 20% of 11 to 16 year olds had been exposed to hate messages online. In addition, youngsters were 12% more likely to be exposed to cyberbullying as compared to 2010, clearly demonstrating that cyberbullying is a growing problem.\nThe prevalence of cybervictimisation depends on the conceptualisation used in describing cyberbullying, but also on research variables such as location and the number and age span of its participants. Nevertheless, the above-mentioned studies demonstrate that online platforms are increasingly used for bullying, which is a cause for concern given its impact. As shown by BIBREF9 , BIBREF10 , BIBREF11 , cyberbullying can have a negative impact on the victim's self-esteem, academic achievement and emotional well-being. BIBREF12 found that self-reported effects of cyberbullying include negative effects on school grades, feelings like sadness, anger, fear, and depression and in extreme cases, cyberbullying could even lead to self-harm and suicidal thoughts.\nThe above studies demonstrate that cyberbullying is a serious problem the consequences of which can be dramatic. Successful early detection of cyberbullying attempts is therefore of key importance to youngsters' mental well-being. However, the amount of information on the Web makes it practically unfeasible for moderators to monitor all user-generated content manually. To tackle this problem, intelligent systems are required that process this information in a fast way and automatically signal potential threats. This way, moderators can respond quickly and prevent threatening situations from escalating. According to recent research, teenagers are generally in favour of such automatic monitoring, provided that effective follow-up strategies are formulated, and that privacy and autonomy are guaranteed BIBREF13 .\nParental control tools (e.g. NetNanny) already block unsuited or undesirable content and some social networks make use of keyword-based moderation tools (i.e., using lists of profane and insulting words to flag harmful content). However, such approaches typically fail to detect implicit or subtle forms of cyberbullying in which no explicit vocabulary is used. There is therefore a need for intelligent and self-learning systems that can go beyond keyword spotting and hence improve recall of cyberbullying detection.\nThe ultimate goal of this sort of research is to develop models which could improve manual monitoring for cyberbullying on social networks. We explore the automatic detection of textual signals of cyberbullying, in which it is approached as a complex phenomenon that can be realised in various ways (see Section SECREF15 for a detailed overview). While a lot of the related research focuses on the detection of cyberbullying `attacks', the present study takes into account a broader range of textual signals of cyberbullying, including posts written by bullies, as well as by victims and bystanders.\nWe propose a machine learning method to cyberbullying detection by making use of a linear SVM classifier BIBREF14 , BIBREF15 exploiting a varied set of features. To the best of our knowledge, this is the first approach to the annotation of fine-grained text categories related to cyberbullying and the detection of signals of cyberbullying events. It is also the first elaborate research on automatic cyberbullying detection on Dutch social media. For the present experiments, we focus on an English and Dutch ASKfm corpus, but the methodology adopted is language and genre independent, provided there is annotated data available.\nThe remainder of this paper is structured as follows: the next section presents a theoretic overview and gives an overview of the state of the art in cyberbullying detection, whereas Section SECREF3 describes the corpus. Next, we present the experimental setup and discuss our experimental results. Finally, Section SECREF6 concludes this paper and provides perspectives for further research.\nThe above studies demonstrate that cyberbullying is a serious problem the consequences of which can be dramatic. Successful early detection of cyberbullying attempts is therefore of key importance to youngsters’ mental well-being.",

        "question": "In data pre-processing, what are other common steps apart from tokenization?",
        "answer": "Lowercasing, removing punctuation, stemming (removing suffixes), lemmatization (converting inflections to a base lemma), and normalization.",
        "evidence": "Preparing the data can be a complex and time-consuming process, often involving working with partially or wholly unstructured data. The pre-processing steps have a big impact on the operationalizations, subsequent analyses and reproducibility efforts BIBREF30 , and they are usually tightly linked to what we intend to measure. Unfortunately, these steps tend to be underreported, but documenting the pre-processing choices made is essential and is analogous to recording the decisions taken during the production of a scholarly edition or protocols in biomedical research. Data may also vary enormously in quality, depending on how it has been generated. Many historians, for example, work with text produced from an analogue original using Optical Character Recognition (OCR). Often, there will be limited information available regarding the accuracy of the OCR, and the degree of accuracy may even vary within a single corpus (e.g. where digitized text has been produced over a period of years, and the software has gradually improved). The first step, then, is to try to correct for common OCR errors. These will vary depending on the type of text, the date at which the `original' was produced, and the nature of the font and typesetting.\nOne step that almost everyone takes is to tokenize the original character sequence into the words and word-like units. Tokenization is a more subtle and more powerful process than people expect. It is often done using regular expressions or scripts that have been circulating within the NLP community. Tokenization heuristics, however, can be badly confused by emoticons, creative orthography (e.g., U$A, sh!t), and missing whitespace. Multi-word terms are also challenging. Treating them as a single unit can dramatically alter the patterns in text. Many words that are individually ambiguous have clear, unmistakable meanings as terms, like “black hole\" or “European Union\". However, deciding what constitutes a multi-word term is a difficult problem. In writing systems like Chinese, tokenization is a research problem in its own right.\nBeyond tokenization, common steps include lowercasing, removing punctuation, stemming (removing suffixes), lemmatization (converting inflections to a base lemma), and normalization, which has never been clearly defined, but often includes grouping abbreviations like “U.S.A.\" and “USA\", ordinals like “1st\" and “first\", and variant spellings like “noooooo\". The main goal of these steps is to improve the ratio of tokens (individual occurrences) to types (the distinct things in a corpus). Each step requires making additional assumptions about which distinctions are relevant: is “apple” different from “Apple”? Is “burnt” different from “burned”? Is “cool\" different from “coooool\"? Sometimes these steps can actively hide useful patterns, like social meaning BIBREF32 . Some of us therefore try do as little modification as possible.\nFrom a multilingual perspective, English and Chinese have an unusually simple inflectional system, and so it is statistically reasonable to treat each inflection as a unique word type. Romance languages have considerably more inflections than English; many indigenous North American languages have still more. For these languages, unseen data is far more likely to include previously-unseen inflections, and therefore, dealing with inflections is more important. On the other hand, the resources for handling inflections vary greatly by language, with European languages dominating the attention of the computational linguistics community thus far.\nWe sometimes also remove words that are not relevant to our goals, for example by calculating vocabulary frequencies. We construct a “stoplist” of words that we are not interested in. If we are looking for semantic themes we might remove function words like determiners and prepositions. If we are looking for author-specific styles, we might remove all words except function words. Some words are generally meaningful but too frequent to be useful within a specific collection. We sometimes also remove very infrequent words. Their occurrences are too low for robust patterns and removing them helps reducing the vocabulary size.\nThe choice of processing steps can be guided by theory or knowledge about the domain as well as experimental investigation. When we have labels, predictive accuracy of a model is a way to assess the effect of the processing steps. In unsupervised settings, it is more challenging to understand the effects of different steps. Inferences drawn from unsupervised settings can be sensitive to pre-processing choices BIBREF33 . Stemming has been found to provide little measurable benefits for topic modeling and can sometimes even be harmful BIBREF34 . All in all, this again highlights the need to document these steps.\nFinally, we can also mark up the data, e.g., by identifying entities (people, places, organizations, etc.) or parts of speech. Although many NLP tools are available for such tasks, they are often challenged by linguistic variation, such as orthographic variation in historical texts BIBREF35 and social media BIBREF32 . Moreover, the performance of NLP tools often drops when applying them outside the training domain, such as applying tools developed on newswire texts to texts written by younger authors BIBREF36 . Problems (e.g., disambiguation in named entity recognition) are sometimes resolved using considerable manual intervention. This combination of the automated and the manual, however, becomes more difficult as the scale of the data increases, and the `certainty' brought by the latter may have to be abandoned.\nBeyond tokenization, common steps include lowercasing, removing punctuation, stemming (removing suffixes), lemmatization (converting inflections to a base lemma), and normalization, which has never been clearly defined6, but often includes grouping abbreviations like “U.S.A.” and “USA”, ordinals like “1st” and “first”, and variant spellings like “noooooo”.",

        "question": "What are the main resources used from MS-COCO?",
        "answer": "Images are used.",
        "evidence": "Generating descriptions for multimedia contents such as images and videos, so called Image Captioning, is helpful for e-commerce companies or news agencies. For instance, in e-commerce field, people will no longer need to put much effort into understanding and describing products' images on their websites because image contents can be recognized and descriptions are automatically generated. Inspired by Horus BIBREF0 , Image Captioning system can also be integrated into a wearable device, which is able to capture surrounding images and generate descriptions as sound in real time to guide people with visually impaired.\nImage Captioning has attracted attentions from researchers in recent years BIBREF1, BIBREF2, BIBREF3, and there has been promising attempts dealing with language barrier in this task by extending existed dataset captions into different languages BIBREF3, BIBREF4.\nIn this study, generating image captions in Vietnamese language is put into consideration. One straightforward approach for this task is to translate English captions into Vietnamese by human or by using machine translation tool, Google translation. With the method of translating directly from English to Vietnamese, we found that the descriptions are sometimes confusing and unnatural to native people. Moreover, image understandings are cultural dependent, as in Western, people usually have different ways to grasp images and different vocabulary choices for describing contexts. For instance, in Fig. FIGREF2, one MS-COCO English caption introduce about \"a baseball player in motion of pitching\", which makes sense and capture accurately the main activity in the image. Though it sounds sensible in English, the sentence becomes less meaningful when we try to translate it into Vietnamese. One attempt of translating the sentence is performed by Google Translation, and the result is not as expected.\n\n\nTherefore, we come up with the approach of constructing a Vietnamese Image Captioning dataset with descriptions written manually by human. Composed by Vietnamese people, the sentences would be more natural and friendlier to Vietnamese users. The main resources we used from MS-COCO for our dataset are images. Besides, we consider having our dataset focus on sportball category due to several reasons:\nBy concentrating on a specific domain we are more likely to improve performance of the Image Captioning models. We expect our dataset can be used to confirm or reject this hypothesis.\nSportball Image Captioning can be used in certain sport applications, such as supportting journalists describing great amount of images for their articles.\nOur primary contributions of this paper are as follows:\nFirstly, we introduce UIT-ViIC, the first Vietnamese dataset extending MS-COCO with manually written captions for Image Captioning. UIT-ViIC is published for research purposes.\nSecondly, we introduce our annotation tool for dataset construction, which is also published to help annotators conveniently create captions.\nFinally, we conduct experiments to evaluate state-of-the-art models (evaluated on English dataset) on UIT-ViIC dataset, then we analyze the performance results to have insights into our corpus.\nThe structure of the paper is organized as follows. Related documents and studies are presented in Section SECREF2. UIT-ViIC dataset creation is described in Section SECREF3. Section SECREF4 describes the methods we implement. The experimental results and analysis are presented in Section SECREF5. Conclusion and future work are deduced in Section SECREF6.\nThe main resources we used from MS-COCO for our dataset are images.",

Indeed, generating always the same question such as “What is the meaning of the universe?\" would be an undesirable behavior, reminiscent of the “collapse mode\" observed in Generative Adversarial Networks (GAN) BIBREF32. Therefore, we adopt Self-BLEU, originally proposed by BIBREF33, as a measure of diversity for the generated text sequences.

If played optimally by both players, the game always ends in a draw, making tic-tac-toe a futile game.",

        "evidence": "Heat shock proteins (HSP) are a family of proteins produced by cells in response to exposure to stressful conditions. They were first described in relation to heat shock, but are now known to also be expressed during other stresses including exposure to cold, UV light and during wound healing or tissue remodeling. Many members of this group perform chaperone functions by stabilizing new proteins to ensure correct folding or by helping to refold proteins that were damaged by the cell stress. This increase in expression is transcriptionally regulated. The dramatic upregulation of the heat shock proteins is a key part of the heat shock response and is induced primarily by heat shock factor (HSF). HSPs are found in virtually all living organisms, from bacteria to humans.",

In short, no one part of the pipeline should be hardcoded to operate within the pipeline, implying other pieces are easily replaced by new and/or better alternative, and the pieces should operate in such a manner that reproducing the exact steps used to create the final dataset is transparent and understandable to those within the broader event data community. Towards this end, the pieces of software are modular in nature; each piece can stand on its own without relying on another other piece of software in the stack. These modular pieces lead to a system that is composable. As pieces can stand on their own, parts of the system can be replaced without affecting the rest of the system in an major way. Finally, the modular and composable nature of the pipeline leads to a system that is inherently reproducible. In many ways, the code itself serves as documentation for reproduction. If the versions of the various pieces are noted, all that is necessary to reproduce the pipeline is to link the correct versions of each module together. Proper design nearly guarantees reproducibility of the data generating process.\nThere are three main considerations at play when designing software surrounding the Phoenix event data pipeline: modularity, composability, and reproducibility.",

        "answer": "CF has two widely known problems which are sparsity and cold start (CS).",
        "evidence": "Today, Internet is one of the widest available media worldwide. It has essentially become a huge hit of data that has the potential to serve many information centric applications in our life. Recommendation system takes an essential part of many internet services and online applications, including applications like social-networking and recommendation of products (films, music, articles,..i.e.). Recommendation techniques have been used by the most known companies such as Amazon, Netflix and eBay to recommend releated items or products by estimating the probable preferences of customers. These techniques are profitable to both service provider and user. According to pervious works, two popular approaches for building recommendation systems can be categorized as content-based (CB), collaborative filtering (CF).\nContent-based (CB) recommending is adopted for recommendation systems model widely, which takes advantage of the property of items to create features and characteristics to coordinate user profiles. It can be relied on the properties of the items that each user likes to discover what else the user may like. One major issue of CB filtering method is that the recommendation system is required to gain an understanding of user preferences for some sorts of items and deploy these for other sorts of items.\nNevertheless CF has two widely known problems which are sparsity and cold start (CS). In the rating matrix, The percentage of elements which get values is small. Even it is possible that CF considers only a few rating for popular items. For instance, upon a considerable Netflix rating dataset which is provided for Netflix Prize competition, there are about 100 milion ratings for about 18,000 movies that are given by 480,000 users. The percentage of rating matrix elements which are received ratings is 1. With a sparse ranking matrix it is very challenging topic to make an effective recommendation, depending on estimation of the relationship between items and users. CS problem is another widely known issue for CF approach, which can occur on new users or items. In terms of achieving an effective recommendation, CF approach requires either ratings on an item or a large number of ratings from a user.\nRecently, researchers proposed various methods based on probabilistic topic modeling methods BIBREF0. LDA is a generative probabilistic model broadly used in the information retrieval field. Researchers have used topic modeling methods based on LDA for building recommendation systems in various subjects, including app recommendation BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, event recommendationBIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10, BIBREF11, BIBREF12, BIBREF13, BIBREF14, BIBREF15, hashtag recommendation BIBREF16, BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21, BIBREF22, BIBREF23, BIBREF24, BIBREF25, BIBREF26, BIBREF27, BIBREF28, BIBREF29, BIBREF30, BIBREF31, BIBREF32, BIBREF33, BIBREF34, BIBREF35, BIBREF36, social networks and media BIBREF37, BIBREF38, BIBREF6, BIBREF9, BIBREF39, BIBREF40, BIBREF41. In this paper, We present a taxonomy of recommendation systems applications based on topic modeling (LDA) of the recent research and evaluate ISWC and WWW publications in computer science between 2013 to 2017 from DBLP dataset.\nNevertheless CF has two widely known problems which are sparsity and cold start (CS).",

        "evidence": "In 1905, T. G. Longstaff, accompanied by two alpine guides and six porters, made an attempt on Gurla Mandhata. They turned back at around 7,000 m (23,000 ft) after being caught in an avalanche and encountering other difficulties. This was a strong achievement for the time, especially for such a small group; at that time no summit of over 7,000 m had yet been climbed and Longstaff's height represented a world altitude record.\n\nIn 1935, a Viennese student, Herbert Tichy, disguised as an Indian pilgrim, made a trip to the holy mountain Kailash. On the way, he attempted Gurla Mandhata with one of his porters, Kitar. They reached a height of 23,400  ft. where they were turned back by fresh snow and bad weather.\n\nIn 1955 the mountain was the intended destination of the inaugural Welsh Himalayan Expedition, led by Sydney Wignall. The expedition, sponsored by the Liverpool Daily Post, intended to summit Gurla Mandata and plant three flags: the Welsh Dragon, the flag of the recently-overthrown Chinese Republic and the Jolly Roger. Before the climb could begin, the group was captured by the Chinese military who imprisoned and tortured the climbers for two months under the belief they were CIA spies (Wignall had in fact offered to spy for India).\n\nThe first ascent of the peak was by a joint Japanese/Chinese team led by Katsutoshi Hirabayashi, via the north side of the peak, in May 1985. Since that time, there have been six additional successful ascents and two failed attempts on the peak.\n\nIn 1997, an attempt was made to ascend the peak via the then-unclimbed North Face route by Quinn Simons, Soren Peters, and their guide, Charlie Fowler. The team made a valiant effort, climbing high on the mountain, but after severe storms and other difficulties had to retreat. Their descent ended in a fall of some 450 m (1,500 ft) down the North Face of the peak. Fowler was slightly injured, while Simons and Peters both suffered extreme frostbite on their extremities.\n\nThe standard ascent route climbs the western flanks of the mountain ascending the Chaglung'mlungha Glacier to the summit plateau. Most teams choose to approach the mountain overland by jeep from either Lhasa, Tibet, or Kathmandu, Nepal. However, an alternate approach begins in the mountain hamlet of Simikot, Nepal, in the remote Humla district of west Nepal and follows the Karnali River northward, crossing into Tibet (China) in the village of Sher. Jeeps then take climbers north through Taklakot (Burang) to basecamp on the mountain.",

        "evidence": "Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research.\n\nMost nuclear power plants use thermal reactors with enriched uranium in a once-through fuel cycle. Fuel is removed when the percentage of neutron absorbing atoms becomes so large that a chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being transferred to long term storage. The spent fuel, though low in volume, is high-level radioactive waste. While its radioactivity decreases exponentially it must be isolated from the biosphere for hundreds of thousands of years, though newer technologies (like fast reactors) have the potential to reduce this significantly. Because the spent fuel is still mostly fissionable material, some countries (e.g. France and Russia) reprocess their spent fuel by extracting fissile and fertile elements for fabrication in new fuel, although this process is more expensive than producing new fuel from mined uranium. All reactors breed some plutonium-239, which is found in the spent fuel, and because Pu-239 is the preferred material for nuclear weapons, reprocessing is seen as a weapon proliferation risk.",

        "question": "Given the reference text about the Spanish-American war, when and how did the war end?",
        "evidence": "The Spanish–American War (April 21 – August 13, 1898) began in the aftermath of the internal explosion of USS Maine in Havana Harbor in Cuba, leading to United States intervention in the Cuban War of Independence. The war led to the United States emerging predominant in the Caribbean region, and resulted in U.S. acquisition of Spain's Pacific possessions. It led to United States involvement in the Philippine Revolution and later to the Philippine–American War.\n\nThe 19th century represented a clear decline for the Spanish Empire, while the United States went from becoming a newly founded country to being a medium regional power. In the Spanish case, the descent, which already came from previous centuries, accelerated first with the Napoleonic invasion, which in turn would cause the independence of a large part of the American colonies, and later political instability (pronouncements, revolutions, civil wars) bled the country socially and economically. The U.S., on the other hand, expanded economically throughout that century by purchasing territories such as Louisiana and Alaska, militarily by actions such as the Mexican–American War, and by receiving large numbers of immigrants. That process was interrupted only for a few years by the American Civil War and Reconstruction era.\n\nThe main issue was Cuban independence. Revolts had been occurring for some years in Cuba against Spanish colonial rule. The United States backed these revolts upon entering the Spanish–American War. There had been war scares before, as in the Virginius Affair in 1873. But in the late 1890s, American public opinion swayed in support of the rebellion because of reports of concentration camps set up to control the populace. Yellow journalism exaggerated the atrocities to further increase public fervor and to sell more newspapers and magazines.\n\nThe business community had just recovered from a deep depression and feared that a war would reverse the gains. Accordingly, most business interests lobbied vigorously against going to war. President William McKinley ignored the exaggerated news reporting and sought a peaceful settlement. Though not seeking a war, McKinley made preparations for readiness against one. He unsuccessfully sought accommodation with Spain on the issue of independence for Cuba. However, after the U.S. Navy armored cruiser Maine mysteriously exploded and sank in Havana Harbor on February 15, 1898, political pressures pushed McKinley into a war that he had wished to avoid.\n\nAs far as Spain was concerned, there was a nationalist agitation, in which the written press had a key influence, causing the Spanish government to not give in and abandon Cuba as it had abandoned Spanish Florida when faced with a troublesome colonial situation there, transferring it to the U.S. in 1821 in exchange for payment of Spanish debts. If the Spanish government had transferred Cuba it would have been seen as a betrayal by a part of Spanish society and there would probably have been a new revolution. So the government preferred to wage a lost war beforehand, rather than risk a revolution, opting for a \"controlled demolition\" to preserve the Restoration Regime.\n\nOn April 20, 1898, McKinley signed a joint Congressional resolution demanding Spanish withdrawal and authorizing the President to use military force to help Cuba gain independence. In response, Spain severed diplomatic relations with the United States on April 21. On the same day, the United States Navy began a blockade of Cuba. Both sides declared war; neither had allies.\n\nThe 10-week war was fought in both the Caribbean and the Pacific. As United States agitators for war well knew, United States naval power would prove decisive, allowing expeditionary forces to disembark in Cuba against a Spanish garrison already facing nationwide Cuban insurgent attacks and further devastated by yellow fever. The invaders obtained the surrender of Santiago de Cuba and Manila despite the good performance of some Spanish infantry units, and fierce fighting for positions such as El Caney and San Juan Hill. Madrid sued for peace after two Spanish squadrons were sunk in the battles of Santiago de Cuba and Manila Bay, and a third, more modern fleet was recalled home to protect the Spanish coasts.\n\nThe war ended with the 1898 Treaty of Paris, negotiated on terms favorable to the United States. The treaty ceded ownership of Puerto Rico, Guam, and the Philippines from Spain to the United States and granted the United States temporary control of Cuba. The cession of the Philippines involved payment of $20 million ($650 million today) to Spain by the U.S. to cover infrastructure owned by Spain.\n\nThe Spanish–American War brought an end to almost four centuries of Spanish presence in the Americas, Asia, and the Pacific. The defeat and loss of the Spanish Empire's last remnants was a profound shock to Spain's national psyche and provoked a thorough philosophical and artistic reevaluation of Spanish society known as the Generation of '98. The United States meanwhile not only became a major power, but also gained several island possessions spanning the globe, which provoked rancorous debate over the wisdom of expansionism.",

        "evidence": "Neural machine translation (NMT) has achieved the state-of-the-art results on a mass of language pairs with varying structural differences, such as English-French BIBREF0, BIBREF1 and Chinese-English BIBREF2. However, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.\nThe understanding of NMT models has been approached primarily from two complementary perspectives. The first thread of work aims to understand the importance of representations by analyzing the linguistic information embedded in representation vectors BIBREF3, BIBREF4 or hidden units BIBREF5, BIBREF6. Another direction focuses on understanding the importance of input words by interpreting the input-output behavior of NMT models. Previous work BIBREF7 treats NMT models as black-boxes and provides explanations that closely resemble the attention scores in NMT models. However, recent studies reveal that attention does not provide meaningful explanations since the relationship between attention scores and model output is unclear BIBREF8.\nIn this paper, we focus on the second thread and try to open the black-box by exploiting the gradients in NMT generation, which aims to estimate the word importance better. Specifically, we employ the integrated gradients method BIBREF9 to attribute the output to the input words with the integration of first-order derivatives. We justify the gradient-based approach via quantitative comparison with black-box methods on a couple of perturbation operations, several language pairs, and two representative model architectures, demonstrating its superiority on estimating word importance.\nWe analyze the linguistic behaviors of words with the importance and show its potential to improve NMT models. First, we leverage the word importance to identify input words that are under-translated by NMT models. Experimental results show that the gradient-based approach outperforms both the best black-box method and other comparative methods. Second, we analyze the linguistic roles of identified important words, and find that words of certain syntactic categories have higher importance while the categories vary across language. For example, nouns are more important for Chinese$\\Rightarrow $English translation, while prepositions are more important for English-French and -Japanese translation. This finding can inspire better design principles of NMT architectures for different language pairs. For instance, a better architecture for a given language pair should consider its own language characteristics.\nHowever, so far not much is known about how and why NMT works, which pose great challenges for debugging NMT models and designing optimal architectures.",

        "evidence": "Machine translation has made remarkable progress, and studies claiming it to reach a human parity are starting to appear BIBREF0. However, when evaluating translations of the whole documents rather than isolated sentences, human raters show a stronger preference for human over machine translation BIBREF1. These findings emphasize the need to shift towards context-aware machine translation both from modeling and evaluation perspective.\nMost previous work on context-aware NMT assumed that either all the bilingual data is available at the document level BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10 or at least its fraction BIBREF11. But in practical scenarios, document-level parallel data is often scarce, which is one of the challenges when building a context-aware system.\nWe introduce an approach to context-aware machine translation using only monolingual document-level data. In our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences. The key idea is to use monolingual data to imitate typical inconsistencies between context-agnostic translations of isolated sentences. The DocRepair model is trained to map inconsistent groups of sentences into consistent ones. The consistent groups come from the original training data; the inconsistent groups are obtained by sampling round-trip translations for each isolated sentence.\nTo validate the performance of our model, we use three kinds of evaluation: the BLEU score, contrastive evaluation of translation of several discourse phenomena BIBREF11, and human evaluation. We show strong improvements for all metrics.\nWe analyze which discourse phenomena are hard to capture using monolingual data only. Using contrastive test sets for targeted evaluation of several contextual phenomena, we compare the performance of the models trained on round-trip translations and genuine document-level parallel data. Among the four phenomena in the test sets we use (deixis, lexical cohesion, VP ellipsis and ellipsis which affects NP inflection) we find VP ellipsis to be the hardest phenomenon to be captured using round-trip translations.\nOur key contributions are as follows:\nwe introduce the first approach to context-aware machine translation using only monolingual document-level data;\nour approach shows substantial improvements in translation quality as measured by BLEU, targeted contrastive evaluation of several discourse phenomena and human evaluation;\nwe show which discourse phenomena are hard to capture using monolingual data only.\nIn our setting, a separate monolingual sequence-to-sequence model (DocRepair) is used to correct sentence-level translations of adjacent sentences.",

The system consists of: 1) a Twitter listener that collects and classifies tweets directed at a known list of women candidates, and 2) a responder that sends out positivitweets when hateful tweets are detected.\nWe collect tweets from Twitter's real-time streaming API. The stream listener uses the open-source Python library Tweepy BIBREF8. The listener analyses tweets in real-time by firing an asynchronous tweet analysis and storage function for each English tweet mentioning one or more candidate usernames of interest. We limit the streaming to English as our text analysis models are trained on English language corpora. We do not track or store retweets to avoid biasing the analysis by counting the same content multiple times. Twitter data is collected and used in accordance with the acceptable terms of use BIBREF9.\nThe tweet analysis and storage function acts as follows: 1) parsing the tweet information to clean and extract the tweet text, 2) scoring the tweet using multiple text analysis models, and 3) storing the data in a database table. We clean tweet text with a variety of rules to ensure that the tweets are cleaned consistent with the expectations of the analysis models (see Appdx SECREF9).\nThe text analysis models classify a tweet by using, as features, the outputs from Perspective API from Jigsaw BIBREF10, HateSonar BIBREF11, and VADER sentiment models BIBREF12. Perspective API uses machine learning models to score the perceived impact a tweet might have BIBREF10. The outputs from these models (i.e. 17 from Perspective, 3 from HateSonar, and 4 from VADER) are combined into a single feature vector for each tweet (see Appdx SECREF10). No user features are included in the tweet analysis models. While these features may improve classification accuracy they can also lead to potential bias BIBREF13.\nWe measure the relative correlation of each feature with the hateful or not hateful labels. We found that Perspective API's TOXICITY probability was the most consistently predictive feature for classifying hateful tweets. Fig. FIGREF5 shows the relative frequencies of hateful and non-hateful tweets over TOXICITY scores. During both elections, we opted to use a single Perspective API feature to trigger sending positivitweets. Using the single TOXICITY feature is almost as predictive as using all features and a more complex model SECREF14. It was also simpler to implement and process tweets at scale. The TOXICITY feature is the only output from the Perspective API with transparent evaluation details summarized in a Model Card BIBREF14, BIBREF15.\nWe collect tweets from Twitter’s real-time streaming API.

Also, advances to ski equipment and slope grooming technology make skiing a lot safer than it used to be years ago.\n\nLearning to ski as an adult may take longer than learning as a child. It is recommended that you start with some lessons first to gain the right technique. This could be group lessons or private lessons. You could also learn from friends who know how to ski, or learn by watching online tutorials and applying them yourself on the mountain. Once you have the basic skills, you should be able to ski easy slopes and start enjoying skiing as a fun activity. \n\nIn addition to lessons, you will also need the right gear to ski. This includes appropriate clothing that can keep you warm on the mountain while you ski, as well as ski equipment that you will use. It is recommended that you get a pair of skis and poles, good fitting boots, a helmet for safety, and goggles to protect your eyes from the elements. Renting your equipment is a good option when you're starting. That way you are not making an expensive commitment upfront. You could also buy your equipment either new or from any of the second-hand ski shops and ski swaps.\n \nWith the right gear and knowledge of the basics, you can take your learning in any direction you want. Many people choose to stay at a beginner or intermediate level and just enjoy the occasional ski trip with friends. While others take their passion forward with more practice, hours on the mountain, and likely more lessons to get to advanced levels.\n\nWhichever path you pick, skiing can be a fun sport to learn and enjoy for the rest of your life.

        "evidence": "For the projection we can use an arbitrary invertible function, and given the representational power of neural networks they seem a natural choice. However, calculating the inverse and Jacobian of an arbitrary neural network can be difficult, as it requires that all component functions be invertible and also requires storage of large Jacobian matrices, which is memory intensive. To address this issue, several recent papers propose specially designed invertible networks that are easily trainable yet still powerful BIBREF16 , BIBREF17 , BIBREF19 . Inspired by these works, we use the invertible transformation proposed by BIBREF16 , which consists of a series of “coupling layers”. This architecture is specially designed to guarantee a unit Jacobian determinant (and thus the invertibility property).\nFrom Eq. ( EQREF22 ) we know that only INLINEFORM0 is required for accomplishing learning and inference; we never need to explicitly construct INLINEFORM1 . Thus, we directly define the architecture of INLINEFORM2 . As shown in Figure FIGREF24 , the nonlinear transformation from the observed embedding INLINEFORM3 to INLINEFORM4 represents the first coupling layer. The input in this layer is partitioned into left and right halves of dimensions, INLINEFORM5 and INLINEFORM6 , respectively. A single coupling layer is defined as: DISPLAYFORM0 \nwhere INLINEFORM0 is the coupling function and can be any nonlinear form. This transformation satisfies INLINEFORM1 , and BIBREF16 show that its Jacobian matrix is triangular with all ones on the main diagonal. Thus the Jacobian determinant is always equal to one (i.e. volume-preserving) and the invertibility condition is naturally satisfied.\nTo be sufficiently expressive, we compose multiple coupling layers as suggested in BIBREF16 . Specifically, we exchange the role of left and right half vectors at each layer as shown in Figure FIGREF24 . For instance, from INLINEFORM0 to INLINEFORM1 the left subset INLINEFORM2 is unchanged, while from INLINEFORM3 to INLINEFORM4 the right subset INLINEFORM5 remains the same. Also note that composing multiple coupling layers does not change the volume-preserving and invertibility properties. Such a sequence of invertible transformations from the data space INLINEFORM6 to INLINEFORM7 is also called normalizing flow BIBREF20 .\nFor the projection we can use an arbitrary invertible function, and given the representational power of neural networks they seem a natural choice.",

Deep representation learning has demonstrated its importance for these tasks. All the tasks get performance improvement via learning either word level representations or sentence level representations.\nIn this work, we brought deep representation learning technologies to the clinical domain. Specifically, we focus on clinical information extraction, using clinical notes and pathology reports from the Mayo Clinic. Our system will identify event expressions consisting of the following components:\nThe input of our system consists of raw clinical notes or pathology reports like below:\nAnd output annotations over the text that capture the key information such as event mentions and attributes. Table TABREF7 illustrates the output of clinical information extraction in details.\nTo solve this task, the major challenge is how to precisely identify the spans (character offsets) of the event expressions from raw clinical notes. Traditional machine learning approaches usually build a supervised classifier with features generated by the Apache clinical Text Analysis and Knowledge Extraction System (cTAKES) . For example, BluLab system BIBREF8 extracted morphological(lemma), lexical(token), and syntactic(part-of-speech) features encoded from cTAKES. Although using the domain specific information extraction tools can improve the performance, learning how to use it well for clinical domain feature engineering is still very time-consuming. In short, a simple and effective method that only leverage basic NLP modules and achieves high extraction performance is desired to save costs.\nTo address this challenge, we propose a deep neural networks based method, especially convolution neural network BIBREF0 , to learn hidden feature representations directly from raw clinical notes.

BIBREF4 classified utterances of speakers as AD or healthy (HC) with an accuracy of INLINEFORM1 using an enlarged, utterance-level view of transcripts of picture descriptions. In line with previous research, we use linguistic and acoustic features of speech as input to our ML model. Furthermore, we extend the model to using data from several different tasks.\nNoorian et al. BIBREF5 demonstrated that using within-task data of healthy participants describing a picture improved AD detection performance by up to 13%. In this paper, we evaluate if model performance improves with the addition of data from healthy participants, with varying ages, performing either the same or different tasks. We find that models trained on datasets of picture description tasks augmented with conversational speech of healthy speakers learn decision boundaries that are more generalizable across activities with lower out-of-task errors. We observe a 9% increase in AD detection performance when normative data from different tasks are utilized. We also analyze if each task provides domain-specific inductive bias for other tasks to obtain a model setting capable of detecting AD from any sample of speech using high-precision model-agnostic explanations proposed by Ribeiro et al. BIBREF6 and computation of various error metrics related to classification.\n\nWe find that models trained on datasets of picture description tasks augmented with conversational speech of healthy speakers learn decision boundaries that are more generalizable across activities with lower out-of-task errors.",

        "evidence": "One of the most fundamental topics in natural language processing is how best to derive high-level representations from constituent parts, as natural language meanings are a function of their constituent parts. How best to construct a sentence representation from distributed word embeddings is an example domain of this larger issue. Even though sequential neural models such as recurrent neural networks (RNN) BIBREF0 and their variants including Long Short-Term Memory (LSTM) BIBREF1 and Gated Recurrent Unit (GRU) BIBREF2 have become the de-facto standard for condensing sentence-level information from a sequence of words into a fixed vector, there have been many lines of research towards better sentence representation using other neural architectures, e.g. convolutional neural networks (CNN) BIBREF3 or self-attention based models BIBREF4 .\nFrom a linguistic point of view, the underlying tree structure—as expressed by its constituency and dependency trees—of a sentence is an integral part of its meaning. Inspired by this fact, some recursive neural network (RvNN) models are designed to reflect the syntactic tree structure, achieving impressive results on several sentence-level tasks such as sentiment analysis BIBREF5 , BIBREF6 , machine translation BIBREF7 , natural language inference BIBREF8 , and discourse relation classification BIBREF9 .\nHowever, some recent works have BIBREF10 , BIBREF11 proposed latent tree models, which learn to construct task-specific tree structures without explicit supervision, bringing into question the value of linguistically-motivated recursive neural models. Witnessing the surprising performance of the latent tree models on some sentence-level tasks, there arises a natural question: Are linguistic tree structures the optimal way of composing sentence representations for NLP tasks?\nIn this paper, we demonstrate that linguistic priors are in fact useful for devising effective neural models for sentence representations, showing that our novel architecture based on constituency trees and their tag information obtains superior performance on several sentence-level tasks, including sentiment analysis and natural language inference.\nA chief novelty of our approach is that we introduce a small separate tag-level tree-LSTM to control the composition function of the existing word-level tree-LSTM, which is in charge of extracting helpful syntactic signals for meaningful semantic composition of constituents by considering both the structures and linguistic tags of constituency trees simultaneously.

First held in 1923, the Spengler Cup is often cited as the oldest invitational ice hockey tournament in the world. The event is hosted by the Swiss team HC Davos and played each year in Davos from 26 December to 31 inclusively. Currently, all games are held at the Eisstadion Davos.\n\nIt was originally devised by Dr. Carl Spengler as a means to promote teams from German-speaking Europe, who might have suffered ostracism in the aftermath of World War I. Eventually, the tournament grew well beyond expectations. Many of Europe's most prestigious clubs and national programs have appeared, including Soviet, Czechoslovak, Swedish, German, and Finnish powerhouses. Through its history, club or national teams from 13 countries have won the tournament, with Team Canada winning the most cups as a club (16) while various teams from Switzerland have won the most cups for one country (20).\n\nAmong non-European organizations, Team Canada, Team USA, nationally ranked U.S. collegiate teams, reigning AHL Calder Cup and Ontario Hockey Association champions, and even Team Japan (in 1971, building international experience before playing as hosts of the 1972 Sapporo Winter Olympics) have competed for the Spengler Cup. Since at least 1990, Team Canada has been the only participant from North America, with the exception of the AHL's Rochester Americans in 1996 and 2013 (see AHL participation at the Spengler Cup).\n\nIn the 2018 tournament, Finnish club team KalPa from the city of Kuopio defeated Team Canada 2–1 in the final. The game was decided in the 8th round of a shootout, the first series of game-winning shots in tournament history that determined the winner of the Spengler Cup.\n\nThe Spengler Cup tournament was not played in 2020 or 2021 due to the COVID-19 pandemic.

        "answer": "To address the word order divergence, the authors propose to pre-order the assisting language sentences (SVO) to match the word order of the source language (SOV).",
        "evidence": "Deep Learning approaches have achieved impressive results on various NLP tasks BIBREF0 , BIBREF1 , BIBREF2 and have become the de facto approach for any NLP task. However, these deep learning techniques have found to be less effective for low-resource languages when the available training data is very less BIBREF3 . Recently, several approaches like Multi-task learning BIBREF4 , multilingual learning BIBREF5 , semi-supervised learning BIBREF2 , BIBREF6 and transfer learning BIBREF7 , BIBREF3 have been explored by the deep learning community to overcome data sparsity in low-resource languages. Transfer learning trains a model for a parent task and fine-tunes the learned parent model weights (features) for a related child task BIBREF7 , BIBREF8 . This effectively reduces the requirement on training data for the child task as the model would have learned relevant features from the parent task data thereby, improving the performance on the child task.\nTransfer learning has also been explored in the multilingual Neural Machine Translation BIBREF3 , BIBREF9 , BIBREF10 . The goal is to improve the NMT performance on the source to target language pair (child task) using an assisting source language (assisting to target translation is the parent task). Here, the parent model is trained on the assisting and target language parallel corpus and the trained weights are used to initialize the child model. The child model can now be fine-tuned on the source-target language pairs, if parallel corpus is available. The divergence between the source and the assisting language can adversely impact the benefits obtained from transfer learning. Multiple studies have shown that transfer learning works best when the languages are related BIBREF3 , BIBREF10 , BIBREF9 . Several studies have tried to address lexical divergence between the source and the target languages BIBREF10 , BIBREF11 , BIBREF12 . However, the effect of word order divergence and its mitigation has not been explored. In a practical setting, it is not uncommon to have source and assisting languages with different word order. For instance, it is possible to find parallel corpora between English and some Indian languages, but very little parallel corpora between Indian languages. Hence, it is natural to use English as an assisting language for inter-Indian language translation.\nTo see how word order divergence can be detrimental, let us consider the case of the standard RNN (Bi-LSTM) encoder-attention-decoder architecture BIBREF13 . The encoder generates contextual representations (annotation vectors) for each source word, which are used by the attention network to match the source words to the current decoder state. The contextual representation is word-order dependent. Hence, if the assisting and the source languages do not have similar word order the generated contextual representations will not be consistent. The attention network (and hence the decoder) sees different contextual representations for similar words in parallel sentences across different languages. This makes it difficult to transfer knowledge learned from the assisting language to the source language.\nWe illustrate this by visualizing the contextual representations generated by the encoder of an English to Hindi NMT system for two versions of the English input: (a) original word order (SVO) (b) word order of the source language (SOV, for Bengali). Figure FIGREF1 shows that the encoder representations obtained are very different. The attention network and the decoder now have to work with very different representations. Note that the plot below does not take into account further lexical and other divergences between source and assisting languages, since we demonstrated word order divergence with the same language on the source side.\nTo address this word order divergence, we propose to pre-order the assisting language sentences to match the word order of the source language. We consider an extremely resource constrained scenario, where we do not have any parallel corpus for the child task. We are limited to a bilingual dictionary for transfer information from the assisting to the source language. From our experiments, we show that there is a significant increase in the translation accuracy for the unseen source-target language pair.\nTo address the word order divergence, we propose to pre-order the assisting language sentences (SVO) to match the word order of the source language (SOV).",

We evaluate our model on the AlgoLisp dataset for this task and achieve state-of-the-art performance. The AlgoLisp dataset BIBREF17 is a program synthesis dataset. Each sample contains a problem description, a corresponding Lisp program tree, and 10 input-output testing pairs. We parse the program tree into a straight-line sequence of tuples (same style as in MathQA). AlgoLisp provides an execution script to run the generated program and has three evaluation metrics: the accuracy of passing all test cases (Acc), the accuracy of passing 50% of test cases (50p-Acc), and the accuracy of generating an exactly matching program (M-Acc).

        "evidence": "We focus on the ALFRED challenge, where an agent is asked to follow human instructions to complete long-horizon household tasks in indoor scenes (simulated in AI2Thor). Each task in ALFRED consists of several subgoals for either navigation (moving in the environment) or object interactions (interacting with at least one object). Language inputs contain a high-level task description and a sequence of low-level step-by-step instructions (each corresponding to a subgoal). The agent is a simulated robot with access to the states of the environment only through a front-view RGB camera with a relatively small field of view. The agent's own state is a 5-tuple (x, y, r, h, o), where x, y are its 2D position, r the horizontal rotation angle, h the vertical camera angles (also called \"horizon\") and o the type of object held in its hand. The state space of the agent is discrete, with navigation actions: MoveAhead (moving forward by 0.25m), RotateLeft & RotateRight (rotating in the horizontal plane by 90 • ) and LookUp & LookDown (adjusting the horizon by 15\nwhere positive h indicates facing downward. With these discrete actions, the agent has full knowledge of the relative changes ∆x, ∆y, ∆r and ∆h. Each of the 7 object interaction actions (PickUp, Open, Slice, etc.) is parametrized by an binary mask for the target object, which is usually predicted with a pre-trained instance segmentation module. Featuring long-horizon tasks with a range of interactions, the ALFRED challenge evaluates an agent's ability to perform tasks over unseen test scenes, while only allowing ≤1000 steps and ≤10 action failures for each task at inference time.\nLanguage inputs contain a high-level task description and a sequence of low-level step-by-step instructions (each corresponding to a subgoal).",

        "question": "What are some tricks to baking a really good cake?",
        "evidence": "",
        "answer": "There are several things to consider when baking a cake.  Paying particular attention to each will produce a consistent and delicious result.  First, confirm that your oven temperature is correct.  This is easily done with a meat thermometer.  Place the thermometer in the middle of the center rack of the oven, where most food cooks. Then preheat the oven to a baking temperature (e.g. 350 degrees).  After the oven has preheated, check the temperature on the thermometer and confirm that it also reads 350 degrees.   Second, bring your refrigerated ingredients to room temperature before using.  If your recipe calls for butter, do not microwave it as a shortcut.  Doing so will change the consistency of your batter.  Plan ahead and leave butter and eggs out on the counter for at least an hour before you begin baking.  Third, pay close attention to recipe instructions related to sifting and measuring flour.  \"Two cups sifted flour\" does not mean the same thing as \"two cups flour, sifted.\"  The first instruction means to sift the flour, then measure; whereas the second means measure first, then sift what was measured.  In either scenario, do not scoop the measuring cup into the flour bin directly.  This causes the flour to be tightly packed into the cup and will result in a cake that has the texture of a brick.  Instead, use a spoon to lightly scoop flour from the bin into the measuring cup, leveling off the top with a butter knife.  This method is messier, but will yield better results.  Fourth, take the time to cream the butter and sugar well.  The result should be smooth and lump free.  This is the most important step to making an appealing cake, and again can't be expedited by using melted butter!  Fifth, if your recipe calls for both wet ingredients (buttermilk, juice etc) and dry (flour mixture), alternate between the two in small increments rather than dumping them in sequentially.  This small step will protect the texture of your cake.  Sixth, once the cake batter has been poured into the pan, lift the pan and drop it onto the counter from a height of two to three inches.  This will remove any air pockets that may have developed in the batter.  Be careful not to bang the pan too hard, or you'll spill the batter and/or scare your pets out of the kitchen.   And lastly, don't bake the cake for as long as the recipe suggests. Set the timer a few minutes early so that you don't over-bake due to any idiosyncrasy associated with your oven (referenced in step one). Please note this does not mean you should be opening and closing the oven door multiple times during the baking process.  Good bakers know \"if you're looking, it's not cooking,\" so try not to open the oven until your timer goes off.  The only exception to this rule is if you smell something burning.  Odds are this means the batter has spilled out over the pan and onto the bottom of the oven.  if this happens, and the oven is now smoking, you have to open the door and try to remove the spill.  If nothing is smoking, leave the mess until the cake is out and the oven has cooled.  Back to the timer - When it goes off, quickly but carefully test the cake with several toothpicks in different areas while the cake remains in the oven. (Taking the cake in and out of the oven to test will change the temperature of both the oven and the cake).  If the toothpicks are wet and sticky, the cake needs more time. If the toothpicks are clean (or a tad moist), the cake is ready to come out of the oven.   Allow cake to cool on a rack, and then enjoy the fruits of your labor!",

Human Rights Watch, for example, called the Saudi endeavor \"an effort to distract from its serious human rights abuses by taking over events that celebrate human achievement\".\n\nGreg Norman has been accused of aiding the repressive Saudi government for his own financial gain. In 2021, Norman denied that he was being used for sportswashing and said he works for LIV because of his passion for the sport. Later, in May 2022, Norman defended the involvement of Saudi Crown Prince Mohammed bin Salman with Jamal Khashoggi's murder, saying, \"Look, we've all made mistakes, and you just want to learn from those mistakes and how you can correct them going forward.\" His statement drew extensive criticism. Khashoggi's fiancée, Hatice Cengiz, said it was hurtful that \"Jamal's brutal killing is brushed off as a 'mistake' and that we should just move on\".\n\nOn 22 June 2022, a group of nearly 2,500 survivors of family members killed or injured during the September 11 attacks wrote an open letter to golfers who have remained loyal to the PGA Tour thanking them for not defecting to LIV Golf. The letter read in part, \"Thank you for standing up for decency. Thank you for standing up for the 9/11 Families. Thank you for resisting the Kingdom of Saudi Arabia's efforts to cleanse its reputation by buying off professional athletes...To those of you who have chosen what is right over blood money from a corrupt, destructive sports entity and its Saudi backers, please continue to stand strong.\" On 17 July 2022, a group of September 11 victims' family members condemned former U.S. President Donald Trump for hosting the LIV Golf tour at his Trump National Golf Club in Bedminster, New Jersey; the group's letter to Trump noted that he himself had blamed Saudi Arabia for the 9/11 attack during a 2016 interview on Fox News.\n\nTiger Woods, who turned down an offer of $700 million to $800 million to join LIV Golf, was asked in July 2022 about the golfers who had joined. \"I disagree with it. I think that what they've done is they've turned their back on what has allowed them to get to this position,\" Woods said at a press conference before the 2022 Open Championship. \"I know what the PGA Tour stands for and what we have done and what the tour has given us, the ability to chase after our careers and to earn what we get and the trophies we have been able to play for and the history that has been a part of this game.\"",

        "question": "What does LiLi consist of?",
        "answer": "A RL model and a lifelong prediction model.",
        "evidence": "We design LiLi as a combination of two interconnected models: (1) a RL model that learns to formulate a query-specific inference strategy for performing the OKBC task, and (2) a lifelong prediction model to predict whether a triple should be in the KB, which is invoked by an action while executing the inference strategy and is learned for each relation as in C-PR. The framework improves its performance over time through user interaction and knowledge retention. Compared to the existing KB inference methods, LiLi overcomes the following three challenges for OKBC:\n1. Mapping open-world to close-world. Being a closed-world method, C-PR cannot extract path features and learn a prediction model when any of INLINEFORM0 , INLINEFORM1 or INLINEFORM2 is unknown. LiLi solves this problem through interactive knowledge acquisition. If INLINEFORM3 is unknown, LiLi asks the user to provide a clue (an example of INLINEFORM4 ). And if INLINEFORM5 or INLINEFORM6 is unknown, LiLi asks the user to provide a link (relation) to connect the unknown entity with an existing entity (automatically selected) in the KB. We refer to such a query as a connecting link query (CLQ). The acquired knowledge reduces OKBC to KBC and makes the inference task feasible.\n2. Spareseness of KB. A main issue of all PR methods like C-PR is the connectivity of the KB graph. If there is no path connecting INLINEFORM0 and INLINEFORM1 in the graph, path enumeration of C-PR gets stuck and inference becomes infeasible. In such cases, LiLi uses a template relation (“@-?-@\") as the missing link marker to connect entity-pairs and continues feature extraction. A path containing “@-?-@\" is called an incomplete path. Thus, the extracted feature set contains both complete (no missing link) and incomplete paths. Next, LiLi selects an incomplete path from the feature set and asks the user to provide a link for path completion. We refer to such a query as missing link query (MLQ).\n3. Limitation in user knowledge. If the user is unable to respond to MLQs or CLQs, LiLi uses a guessing mechanism (discussed later) to fill the gap. This enables LiLi to continue its inference even if the user cannot answer a system question.\nWe design LiLi as a combination of two interconnected models: (1) a RL model that learns to formulate a query-specific inference strategy for performing the OKBC task, and (2) a lifelong prediction model to predict whether a triple should be in the KB, which is invoked by an action while executing the inference strategy and is learned for each relation as in C-PR.

        "evidence": "An important barrier to the safe deployment of machine learning systems is the risk of task ambiguity, where multiple behaviors are consistent with the provided examples. We investigate whether pretrained models are better active learners, capable of asking for example labels that disambiguate between the possible tasks a user may be trying to specify. Across a range of image and text datasets with spurious correlations, latent minority groups, or domain shifts, finetuning pretrained models with data acquired through simple uncertainty sampling achieves the same accuracy with up to 6× fewer labels compared to random sampling. Moreover, the examples chosen by these models are preferentially minority classes or informative examples where the spurious feature and class label are decorrelated. Notably, gains from active learning are not seen in unpretrained models, which do not select such examples, suggesting that the ability to actively learn is an emergent property of the pretraining process.Figure 1: Active learning can resolve task ambiguity, which is especially salient in few-shot settings. Here, the provided training data leaves the model unsure of the task: is it to predict the shape or the color of the object? Pretraining enables models to disentangle and weigh various competing features, making them good active learners that can choose disambiguating examples (e.g. the blue square), resolving this task ambiguity.\nVision For computer vision datasets, we finetune BiT, a recentlyproposed family of vision models which have achieved state-of-the-art performance on several vision tasks.

These models have been shown to have emergent few-shot learning abilities, where strong classifiers for new tasks can be obtained by simply finetuning on tens or hundreds of examples with typical gradient descent techniques (rather than meta-learning techniques, for example).\nText For the text dataset (Amazon), we use RoBERTa-Large, another pretrained model with similar properties as BiT, and a representative of the BERT family of models which together have obtained state-of-the-art scores on modern NLP benchmarks.\nOther details, including hyperparameters and seed set/acquisition sizes are deferred to Appendix B.\nAs a running baseline, we compare to the same model finetuned with a random acquisition function (equivalent to not doing active learning).

BanerjeeP03 extended this idea to WordNet, but observed that WordNet glosses are often very short, and did not contain enough information to distinguish between multiple concepts. Therefore, they created a super–gloss for each concept by adding the glosses of related concepts to the gloss of the concept itself (and then finding overlaps).\nPatwardhanP06 adapted this measure to second–order co–occurrence vectors. In this approach, a vector is created for each word in a concept's definition that shows which words co–occur with it in a corpus. These word vectors are averaged to create a single co-occurrence vector for the concept. The similarity between the concepts is calculated by taking the cosine between the concepts second–order vectors.

Depending on the jurisdiction, entities such as corporations, other types of firm, partnerships and state-owned enterprises may be treated as legal persons, with both rights and responsibilities under law. Successor liability rules influence how these rights and responsibilities vis-a-vis others are influenced by corporate restructurings.\n\nUnder corporate law (or possibly other bodies of law, such as employment or environmental law), some countries regulate how liability passes from a ‘predecessor’ entity to a 'successor' entity in the event of such corporate restructurings as a name change, merger or acquisition, division or dissolution. Following such restructurings, successor liability rules determine whether and how the 'successor' or acquiring entity must assume some or all of the predecessor entity's liabilities. Product liability, environmental clean-up, employment law and criminal law are some of the areas in which successor liability may enter into play. Thus, it is an important component of the legal system that supports the structural change needed in dynamic business sectors while also protecting individual and societal interests.\n\nWhile a restructuring does not automatically give rise to successor liability, the following situations are often considered to be relevant when determining whether or not such liability exists: there is an explicit agreement between the parties on the assumption of some liabilities; the restructuring is considered to be a de facto merger; the restructuring results in the mere continuation of the predecessor’s business; and the transaction underpinning the restructuring was fraudulent and used to escape liability.\n\nWithout successor liability, a business entity may avoid liability by reorganising itself or otherwise altering its corporate identity. A comparative law study of successor liability in the context of enforcement of laws criminalising foreign bribery shows that countries have adopted widely different approaches to successor liability in a criminal law context. In some jurisdictions, it is not clear whether successor liability exists at all, opening up the possibility that even minor business reorganisations could 'wipe the slate clean' from the standpoint of criminal law enforcement. Other countries have comprehensive statutory frameworks that address successor liability. Still others rely on established jurisprudence or other legal principles as the legal foundation for successor liability.",

        "answer": "REST API is an architectural style for building network APIs. In practice, most REST APIs are using JSON over HTTP. REST APIs have several properties that make them very popular.\n\nHTTP is the foundational and the most popular network protocol across the internet. By using HTTP, REST APIs can fully utilize the internet infrastructure, which greatly reduce the complexity and operational costs. For example, using HTTPS for transport security, and using URL for request routing.\n\nJSON is a simple, stable, and intuitive data format , which is not expected to change ever. This offers great ease of use and stability to REST APIs. For high performance applications, binary formats can be used instead, such as protobuf or thrift.\n\nREST APIs are often designed as CRUD APIs, where API operations are commonly expressed as Create, Retrieve, Update, and Delete operations on resources. CRUD operations are naturally mapped to HTTP methods (POST, GET, PUT/PATCH, and DELETE), and API resources can be naturally identified using URLs.",

In BIBREF0 we demonstrated deep learning based automatic speech recognition (ASR) using EEG signals for a limited English vocabulary of four words and five vowels. In this paper we extend our work for a much larger English vocabulary and we use state-of-art end-to-end continuous speech recognition models to perform recognition. In our prior work we predicted isolated words and vowels.\nASR systems forms the front end or back end in many cutting edge voice activated technologies like Amazon Alexa, Apple Siri, Windows Cortana, Samsung Bixby etc. Unfortunately these systems are trained to recognize text only from acoustic features. This limits technology accessibility to people with speaking disabilities and disorders. The research work presented in this paper tries to address this issue by investigating speech recognition using only EEG signals with no acoustic input and also by combining EEG features along with traditional acoustic features to perform recognition. We believe the former will help with speech restoration for people who can not speak at all and the latter will help people who are having speaking disabilities like broken or discontinued speech etc to use voice activated technologies with better user experience there by helping in improving technology accessibility.\nASR performance is degraded in presence of noisy speech and in real life situations most of the speech is noisy. Inspired from the unique robustness to environmental artifacts exhibited by the human auditory cortex BIBREF1 , BIBREF2 we used very noisy speech data for this work and demonstrated lower word error rate (WER) for smaller corpus using EEG features, concatenation of EEG features and acoustic features.\nIn BIBREF3 authors decode imagined speech from EEG using synthetic EEG data and connectionist temporal classification (CTC) network but in our work we use real EEG data, use EEG data recorded along with acoustics. In BIBREF4 authors perform envisioned speech recognition using random forest classifier but in our case we use end to end state of art models and perform recognition for noisy speech.

Sentence representation is a challenging task that has to consider aspects such as compositionality, phrase similarity, negation, etc. In order to evaluate sentence representations, intermediate tasks such as Semantic Textual Similarity (STS) BIBREF1 or Natural Language Inference (NLI) BIBREF2 have been proposed, with STS being popular among unsupervised approaches. Through a set of campaigns, STS has produced several manually annotated datasets, where annotators measure the similarity among sentences, with higher scores for more similar sentences, ranging between 0 (no similarity) to 5 (semantic equivalence). Human annotators exhibit high inter-tagger correlation in this task.\nIn another strand of related work, tasks that combine representations of multiple modalities have gained increasing attention, including image-caption retrieval, video and text alignment, caption generation, and visual question answering. A common approach is to learn image and text embeddings that share the same space so that sentence vectors are close to the representation of the images they describe BIBREF3 , BIBREF4 . BIBREF5 provides an approach that learns to align images with descriptions. Joint spaces are typically learned combining various types of deep learning networks such us recurrent networks or convolutional networks, with some attention mechanism BIBREF6 , BIBREF7 , BIBREF8 .\nThe complementarity of visual and text representations for improved language understanding have been shown also on word representations, where embeddings have been combined with visual or perceptual input to produce grounded representations of words BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 . These improved representation models have outperformed traditional text-only distributional models on a series of word similarity tasks, showing that visual information coming from images is complementary to textual information.\nIn this paper we present Visual Semantic Textual Similarity (vSTS), a dataset which allows to study whether better sentence representations can be built when having access to corresponding images, e.g. a caption and its image, in contrast with having access to the text alone. This dataset is based on a subset of the STS benchmark BIBREF1 , more specifically, the so called STS-images subset, which contains pairs of captions. Note that the annotations are based on the textual information alone. vSTS extends the existing subset with images, and aims at being a standard dataset to test the contribution of visual information when evaluating sentence representations.\nIn addition we show that the dataset allows to explore two hypothesis: H1) whether the image representations alone are able to predict caption similarity; H2) whether a combination of image and text representations allow to improve the text-only results on this similarity task.\nWe introduced the vSTS dataset, which contains caption pairs with human similarity annotations, where the systems can also access the actual images. The dataset aims at being a standard dataset to test the contribution of visual information when evaluating the similarity of sentences.\nExperiments confirmed our hypotheses: image representations are useful for caption similarity and they are complementary to textual representations, as results improve significantly when two modalities are combined together.\nIn the future we plan to re-annotate the dataset with scores which are based on both the text and the image, in order to shed light on the interplay of images and text when understanding text.\nIn addition we show that the dataset allows to explore two hypothesis: H1) whether the image representations alone are able to predict caption similarity; H2) whether a combination of image and text representations allow to improve the text-only results on this similarity task.

MARN has two key components: Long-short Term Hybrid Memory and Multi-attention Block. Long-short Term Hybrid Memory (LSTHM) is an extension of the Long-short Term Memory (LSTM) by reformulating the memory component to carry hybrid information. LSTHM is intrinsically designed for multimodal setups and each modality is assigned a unique LSTHM. LSTHM has a hybrid memory that stores view-specific dynamics of its assigned modality and cross-view dynamics related to its assigned modality. The component that discovers cross-view dynamics across different modalities is called the Multi-attention Block (MAB). The MAB first uses information from hidden states of all LSTHMs at a timestep to regress coefficients to outline the multiple existing cross-view dynamics among them. It then weights the output dimensions based on these coefficients and learns a neural cross-view dynamics code for LSTHMs to update their hybrid memories. Figure 1 shows the overview of the MARN. MARN is differentiable end-to-end which allows the model to be learned efficiently using gradient decent approaches. In the next subsection, we first outline the Long-short Term Hybrid Memory. We then proceed to outline the Multi-attention Block and describe how the two components are integrated in the MARN.\nLong-short Term Memory (LSTM) networks have been among the most successful models in learning from sequential data BIBREF21 .

He devoted much of his life to the conservation of bush remnants on the Port Hills on Banks Peninsula, and a key element in his scheme was to make the area accessible to the public. To that end, he proposed a Summit Road that would go along the hilltops, connecting Godley Head with the tops above Akaroa. Whilst most of the public believed that the scenic reserves to be formed were too remote, Ell had a way with landowners and organised some government funding. His usual style was to pay a deposit for land, with the remainder to be raised later. In 1909, he decided to form a Summit Road Scenic Reserve Board to help with the task of establishing his dream, but there was tension over their scope. The board wanted to have influence on policy, but Ell regarded them as a mere fund-raising body. By 1915, Ell had secured 23 reserves in the Port Hills by buying private land, and none of these projects had the board's prior approval.\n\nBy the 1930s, the road had been surveyed as far south as the saddle above Pigeon Bay.\n\nRest houses were envisaged at regular intervals. The first to be built was the Sign of the Bellbird at Kennedy's Bush in 1914. This was the location of the first scenic reserve that Ell managed to get established in 1906. The Sign of the Packhorse, a smaller house on top of the Kaituna Saddle, was the second one to be established in 1916. The Sign of the Kiwi was the third rest house built by Ell.

        "question": "What is the difference between an electric field and gravitational field?",
        "evidence": "The concept of the electric field was introduced by Michael Faraday. An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field. The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses, and like it, extends towards infinity and shows an inverse square relationship with distance. However, there is an important difference. Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion. Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero. Thus gravity is the dominant force at distance in the universe, despite being much weaker.\nAn electric field generally varies in space and its strength at any one point is defined as the force (per unit charge) that would be felt by a stationary, negligible charge if placed at that point. The conceptual charge, termed a 'test charge', must be vanishingly small to prevent its own electric field disturbing the main field and must also be stationary to prevent the effect of magnetic fields. As the electric field is defined in terms of force, and force is a vector, having both magnitude and direction, so it follows that an electric field is a vector field.\nThe study of electric fields created by stationary charges is called electrostatics. The field may be visualised by a set of imaginary lines whose direction at any point is the same as that of the field. This concept was introduced by Faraday, whose term 'lines of force' still sometimes sees use. The field lines are the paths that a point positive charge would seek to make as it was forced to move within the field; they are however an imaginary concept with no physical existence, and the field permeates all the intervening space between the lines. Field lines emanating from stationary charges have several key properties: first, that they originate at positive charges and terminate at negative charges; second, that they must enter any good conductor at right angles, and third, that they may never cross nor close in on themselves.",
        "answer": "The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses, and like it, extends towards infinity and shows an inverse square relationship with distance. However, there is an important difference. Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion.",

        "evidence": "Time series data in the real world is high dimensional, unstructured, and complex with unique properties, leading to challenges for data modeling. In addition, without human recognizable patterns, it is much harder to label time series data than images and languages in realworld applications. These labeling limitations hinder deep learning methods, which typically require a huge amount of labeled data for training, been applied on time series data. Representation learning learns a fixed-dimension embedding from the original time series that keeps their inherent features. Comparing to the raw time series data, these representations are with better transferability and generalization capacity. To deal with labeling limitations, contrastive learning methods have been widely adopted in various domains for their soaring performance on representation learning, including vision, language, and graph-structured data. In a nutshell, contrastive learning methods typically train an encoder to map instances to an embedding space where dissimilar (negative) instances are easily distinguishable from similar (positive) ones and model predictions to be invariant to small noise applied to either input examples or hidden states.\nDespite being effective and prevalent, contrastive learning has been less explored in the time series domain. Existing contrastive learning approaches often involve a specific data augmentation strategy that creates novel and realistic-looking training data without changing its label to construct positive alternatives for any input sample. Their success relies on carefully designed rules of thumb guided by domain expertise. Routinely used data augmentations for contrastive learning are mainly designed for image and language data, such as color distortion, flip, word replacement, and back-translation. These augmentation techniques generally do not apply to time series data.\nFigure: InfoTS is composed of three parts: (1) candidate transformation that generates different augmentations of the original inputs, (2) a meta-network that selects the optimal augmentations, (3) an encoder that learns representations of time series instances. The meta-network is learned in tandem with contrastive encoder learning.\nRecently, some researchers propose augmentations for time series to enhance the size and quality of the training data. For example, and propose to adopt jittering, scaling, and permutation strategies to generate augmented instances. extracts subsequences for data augmentation. In spite of the current progress, existing methods have two main limitations. First, unlike images with human recognizable features, time series data are often associated with inexplicable underlying patterns. Strong augmentation such as permutation may ruin such patterns and consequently, the model will mistake the negative handcrafts for positive ones. While weak augmentation methods such as jittering may generate augmented instances that are too similar to the raw inputs to be informative enough for contrastive learning. On the other hand, time series datasets from different domains may have diverse nature. Adapting a universal data augmentation method, such as subsequence in, for all datasets and tasks leads to sub-optimal performances. Other works follow empirical rules to select suitable augmentations from expensive trial-and-error. Akin to hand-crafting features, hand-picking choices of data augmentations are undesirable from the learning perspective. The diversity and heterogeneity of real-life time series data further hinder these methods away from wide applicability.\nTo address the challenges, we first introduce the criteria for selecting good data augmentations in contrastive learning. Data augmentation benefits generalizable, transferable, and robust representation learning by correctly extrapolating the input training space to a larger region. The positive instances enclose a discriminative zone in which all the data points should be similar to the original instance. The desired data augmentations for contrastive representation learning should have both high fidelity and high variety. High fidelity encourages the augmented data to maintain the semantic identity that is invariant to transformations. For example, if the downstream task is classification, then the generated augmentations of inputs should be class-preserving. Meanwhile, generating augmented samples with high variety benefits representation learning by increasing the generalization capacity. From the motivation, we theoretically analyze the information flows in data augmentations based upon information theory and derive the criteria for selecting desired time series augmentations. Due to the inexplicability in practical time series data, we assume that the semantic identity is presented by the target in the downstream task. Thus, high fidelity can be achieved by maximizing the mutual information between the downstream label and the augmented data. A one-hot pseudo label is assigned to each instance in the unsupervised setting when downstream labels are unavailable. These pseudo labels encourage augmentations of different instances to be distinguishable from each other. We show that data augmentations preserving these pseudo labels can add new information without decreasing the fidelity. Concurrently, we maximize the entropy of augmented data conditional on the original instances to increase the variety of data augmentations.\nBased on the derived criteria, we propose an adaptive data augmentation method, InfoTS (as shown in Figure), by employing a meta-learning mechanism to avoid ad-hoc choices or painstakingly trial-and-error tuning. Specifically, we utilize a meta-network to learn the augmentation prior in tandem with contrastive learning. The meta-learner automatically selects optimal augmentations from candidate augmentations to generate feasible positive samples. Along with random sampled negative instances, augmented instances are then fed into a time series encoder to learn representations in a contrastive manner. With a reparameterization trick, the meta-network can be efficiently optimized with back-propagation based upon the proposed criteria. Therefore, the meta-network can automatically select data augmentations in a per dataset and per learning task manner without resorting to expert knowledge or tedious downstream validation. Our main contributions include:\n• We propose criteria to guide the selection of data augmentations for contrastive time series representation learning without prefabricated knowledge. • We propose a meta-learning based method to automatically select feasible data augmentations for different time series datasets, which can be efficiently optimized with backpropagation. • We empirically verify the effectiveness of the proposed criteria to find optimal data augmentations. Extensive experiments demonstrate that InfoTS can achieve highly competitive performance with up to 11.4% reduction in MSE on forecasting task and up to 2.8% relative improvement in accuracy on classification task over the leading baselines.\nWe empirically verify the effectiveness of the proposed criteria to find optimal data augmentations.

We also tested a Base-Softmax model, which replaces the CRF output of the Base model with a softmax. A comparison of the results of these three models can be seen in Table TABREF25. This comparison empirically motivates the CRF output because Base almost always outperforms Base-Softmax. Of these three models, the Base model performed the best with the exception of the French and Manipuri datasets. The differences in the French results can be considered negligible because the accuracies are all near $100\\%$. The Small model performed best on Manipuri, which may suggest that reducing the number of parameters of the Base model leads to better accuracy on smaller datasets.\nFLOAT SELECTED: TABLE III THE ACCURACY OF OUR PROPOSED MODEL ON EACH EVALUATION DATASET.

If you were advising a group seeking to guarantee certain civil rights today (for example, disabled people, gays/lesbians, or immigrants) which would you advise them to use?",
        "evidence": "",
        "answer": "There were four strategies employed by the leaders of the modern civil rights movement.  The first was legalism, which used the courts to attack discriminatory laws or practices.  The limits of legalism are the cost, slow change, burden on the individual and it was elite driven.  The second was nonviolent direct action (NVDA).  NVDA identifies an unjust law which is then broken by individuals trying to promote change.  Individuals must then accept the consequences of breaking the law, but if enough do so, it puts pressure on local governments.  The third strategy was political action, which used voting on proactive agendas to force change.  Finally, the fourth strategy was the black power movement.  This strategy promoted disengagement from white-society and setting up a separate black power structure.  It provided services to the black community and promoted positive black images, but had weak leadership and was prone to violence and paranoia.\nIf I was advising a civil rights group today, I would advise them to use the first three strategies.  Legalism, NVDA and political action are positive and effective ways to enable change.  They usually encourage sympathetic news coverage and get the message of the group out to the broader public.  A strategy like the black power movement would not be effective.  If you want to change society, you can’t separate from it or try to change it from the outside.  You need to work within the system to change it. Violence will also turn public support away from your group and allow government agencies to crack down on your leadership, making it hard to continue to bring about the change you desire.",

The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are \"out\"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches. They communicate with two off-field scorers who record the match's statistical information.\n\nForms of cricket range from Twenty20, with each team batting for a single innings of 20 overs (each \"over\" being a set of 6 fair opportunities for the batting team to score) and the game generally lasting three hours, to Test matches played over five days.

        "question": "Does the BD pose special challenges compared to other mental health issues?",
        "answer": "Yes, it does.",
        "evidence": "Recent years have witnessed increased performance in many computational linguistics tasks such as syntactic and semantic parsing BIBREF0 , BIBREF1 , emotion classification BIBREF2 , and sentiment analysis BIBREF3 , BIBREF4 , BIBREF5 , especially concerning the applicability of such tools to noisy online data. Moreover, the field has made substantial progress in developing multilingual models and extending semantic annotation resources to languages beyond English BIBREF6 , BIBREF7 , BIBREF8 , BIBREF9 .\nConcurrently, it has been argued for mental health research that it would constitute a `valuable critical step' BIBREF10 to analyse first-hand accounts by individuals with lived experience of severe mental health issues in blog posts, tweets, and discussion forums. Several severe mental health difficulties, e.g., bipolar disorder (BD) and schizophrenia are considered as chronic and clinical recovery, defined as being relapse and symptom free for a sustained period of time BIBREF11 , is considered difficult to achieve BIBREF12 , BIBREF13 , BIBREF14 . Moreover, clinically recovered individuals often do not regain full social and educational/vocational functioning BIBREF15 , BIBREF16 . Therefore, research originating from initiatives by people with lived experience of mental health issues has been advocating emphasis on the individual's goals in recovery BIBREF17 , BIBREF18 . This movement gave rise to the concept of personal recovery BIBREF19 , BIBREF20 , loosely defined as a `way of living a satisfying, hopeful, and contributing life even with limitations caused by illness' BIBREF18 . The aspects of personal recovery have been conceptualised in various ways BIBREF21 , BIBREF22 , BIBREF23 . According to the frequently used CHIME model BIBREF24 , its main components are Connectedness, Hope and optimism, Identity, Meaning and purpose, and Empowerment. Here, we focus on BD, which is characterised by recurring episodes of depressed and elated (hypomanic or manic) mood BIBREF25 , BIBREF12 . Bipolar spectrum disorders were estimated to affect approximately 2% of the UK population BIBREF13 with rates ranging from 0.1%-4.4% across 11 other European, American and Asian countries BIBREF26 . Moreover, BD is associated with a high risk of suicide BIBREF27 , making its prevention and treatment important tasks for society. BD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression BIBREF25 . Second, unlike for some other severe mental health difficulties, return to normal functioning is achievable given appropriate treatment BIBREF28 , BIBREF16 , BIBREF29 .\nA substantial body of qualitative and quantitative research has shown the importance of personal recovery for individuals diagnosed with BD BIBREF22 , BIBREF25 , BIBREF30 , BIBREF31 , BIBREF23 . Qualitative evidence mainly comes from (semi-)structured interviews and focus groups and has been criticised for small numbers of participants BIBREF10 , lacking complementary quantitative evidence from larger samples BIBREF32 . Some quantitative evidence stems from the standardised bipolar recovery questionnaire BIBREF30 and a randomised control trial for recovery-focused cognitive-behavioural therapy BIBREF31 . Critically, previous research has taken place only in structured settings. What is more, the recovery concept emerged from research primarily conducted in English-speaking countries, mainly involving researchers and participants of Western ethnicity. This might have led to a lack of non-Western notions of wellbeing in the concept, such as those found in indigenous peoples BIBREF32 , limiting its the applicability to a general population. Indeed, the variation in BD prevalence rates from 0.1% in India to 4.4% in the US is striking. It has been shown that culture is an important factor in the diagnosis of BD BIBREF33 , as well as on the causes attributed to mental health difficulties in general and treatments considered appropriate BIBREF34 , BIBREF35 . While approaches to mental health classification from texts have long ignored the cultural dimension BIBREF36 , first studies show that online language of individuals affected by depression or related mental health difficulties differs significantly across cultures BIBREF37 , BIBREF36 .\nHence, it seems timely to take into account the wealth of accounts of mental health difficulties and recovery stories from individuals of diverse ethnic and cultural backgrounds that are available in a multitude of languages on the internet. Corpus and computational linguistic methods are explicitly designed for processing large amounts of linguistic data BIBREF38 , BIBREF39 , BIBREF40 , BIBREF41 , and as discussed above, recent advances have made it feasible to apply them to noisy user-generated texts from diverse domains, including mental health BIBREF42 , BIBREF43 . Computer-aided analysis of public social media data enables us to address several shortcomings in the scientific underpinning of personal recovery in BD by overcoming the small sample sizes of lab-collected data and including accounts from a more heterogeneous population.\nIn sum, our research questions are as follows: (1) How is personal recovery discussed online by individuals meeting criteria for BD? (2) What new insights do we get about personal recovery and factors that facilitate or hinder it? We will investigate these questions in two parts, looking at English-language data by westerners and at multilingual data by individuals of diverse ethnicities.\nBD-specific personal recovery research is motivated by mainly two facts: First, the pole of positive/elevated mood and ongoing mood instability constitute core features of BD and pose special challenges compared to other mental health issues, such as unipolar depression (Jones et al., 2010).",

        "evidence": "Language variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US). Although at first sight language variety identification may seem a classical text classification problem, cultural idiosyncrasies may influence the way users construct their discourse, the kind of sentences they build, the expressions they use or their particular choice of words. Due to that, we can consider language variety identification as a double problem of text classification and author profiling, where information about how language is shared by people may help to discriminate among classes of authors depending on their language variety.\nThis task is specially important in social media. Despite the vastness and accessibility of the Internet destroyed frontiers among regions or traits, companies are still very interested in author profiling segmentation. For example, when a new product is launched to the market, knowing the geographical distribution of opinions may help to improve marketing campaigns. Or given a security threat, knowing the possible cultural idiosyncrasies of the author may help to better understand who could have written the message.\nLanguage variety identification is a popular research topic of natural language processing. In the last years, several tasks and workshops have been organized: the Workshop on Language Technology for Closely Related Languages and Language Variants @ EMNLP 2014; the VarDial Workshop @ COLING 2014 - Applying NLP Tools to Similar Languages, Varieties and Dialects; and the LT4VarDial - Joint Workshop on Language Technology for Closely Related Languages, Varieties and Dialect @ RANLP BIBREF0 BIBREF1 . We can find also several works focused on the task. In BIBREF2 the authors addressed the problem of identifying Arabic varieties in blogs and social fora. They used character $n$ -gram features to discriminate between six different varieties and obtained accuracies between 70%-80%. Similarly, BIBREF3 collected 1,000 news articles of two varieties of Portuguese. They applied different features such as word and character $n$ -grams and reported accuracies over 90%. With respect to the Spanish language, BIBREF4 focused on varieties from Argentina, Chile, Colombia, Mexico and Spain in Twitter. They used meta-learning and combined four types of features: i) character $n$ -gram frequency profiles, ii) character $n$ -gram language models, iii) Lempel-Ziv-Welch compression and iv) syllable-based language models. They obtained an interesting 60%-70% accuracy of classification.\nWe are interested in discovering which kind of features capture higher differences among varieties. Our hypothesis is that language varieties differ mainly in lexicographic clues. We show an example in Table 1 .\n In this work we focus on the Spanish language variety identification. We differentiate from the previous works as follows: i) instead of $n$ -gram based representations, we propose a low dimensionality representation that is helpful when dealing with big data in social media; ii) in order to reduce the possible over-fitting, our training and test partitions do not share any author of instance between them; and iii) in contrast to the Twitter dataset of BIBREF4 , we will make available our dataset to the research community.\nLanguage variety identification aims at labelling texts in a native language (e.g. Spanish, Portuguese, English) with their specific variation (e.g. Argentina, Chile, Mexico, Peru, Spain; Brazil, Portugal; UK, US).",

        "question": "What kind of task does the decoder handle compared with the encoder?",
        "answer": "An easier task.",
        "evidence": "The encoder-decoder based framework BIBREF0, BIBREF1, BIBREF2 is the dominant approach for neural machine translation (NMT) BIBREF3, BIBREF4. Although the encoder and decoder usually adopt the same model structure (RNN BIBREF5, CNN BIBREF6 or self-attention BIBREF3, BIBREF7) and the same number of layers, they perform different functionalities: the encoder extracts the hidden representations of the source sentence, and the decoder generates target tokens conditioned on the source hidden representations as well as the previous generated tokens.\nWhile most existing works focus on the design and improvement of encoder-decoder framework for NMT BIBREF8, BIBREF6, BIBREF3, BIBREF9 as well as its detailed analyses BIBREF10, BIBREF11, BIBREF12, BIBREF13, few works concentrate on the characteristics and functionalities of the encoder and the decoder, which are valuable to understand this popular framework and improve its performance in NMT. Therefore, in this paper, we conduct a study and aim to understand the characteristics of the encoder and the decoder in NMT. We observe some interesting phenomena:\nThe decoder handles an easier task than the encoder. 1) We find that adding more layers to the encoder achieves larger improvements than adding more layers to the decoder. 2) We also compare the training time of the encoder and decoder by fixing the parameters of a well-trained decoder (encoder), and just update the parameters of the encoder (decoder). We found that the decoder converges faster than the encoder. These two results suggest that the decoder handles an easier task than the encoder in NMT.\nThe decoder is more sensitive to the input noise than the encoder. We randomly add different level of noise to the input of the encoder and decoder respectively during inference, and find that adding noise to the input of the decoder leads to better accuracy drop than that of the encoder.\nWe further analyze why the decoder is more sensitive by masking the previous tokens, and comparing autoregressive NMT with the non-autoregressive counterpart. We find that the preceding tokens in the decoder provide strong conditional information, which partially explain the previous two observations on the decoder.\nWe believe our studies on the different characteristics of the encoder and decoder will inspire the following research on the encoder-decoder framework as well as improve the performance on NMT and other encoder-decoder based tasks.\nThe decoder handles an easier task than the encoder.",

Our experiment results in Section 4 show that even k=1 can improve the source model. The framework of our proposed method also applies when there are more than k samples per class.",
        "evidence": "While deep neural networks have demonstrated remarkable ability in representation learning, their performance relies heavily on the assumption that training (source) and test (target) data distributions are the same. Real-world data collection is often resource-constrained, such that test samples may be subject to domain shift, also known as covariate shift, due to factors such as illumination, pose, style and data collection procedures. To prevent severe performance degradation when models are deployed, adaptation to the target distribution is needed.\nA range of methods to address domain shift have been developed, with varying requirements on source and target domain data. Domain generalization considers generalization without seeing target data, but existing methods still have a considerable generalization gap. On the other hand, domain adaptation (DA) assumes the availability of target data during training. Most DA methods work under the vanilla unsupervised DA (UDA) setting, taking that labelled source and unlabelled target data are fully accessible for joint training. Some methods have been proposed under the few-shot DA setting, which assume that labelled source data and a few labelled target samples are available. Recent work is shifting towards a more challenging setting of source-free UDA, where a pre-trained source model is adapted with only unlabelled target data. However, these methods require access to the entire target dataset during adaptation.\nVery recently, test-time adaptation methods have been proposed to continuously adapt during test time with streaming unlabelled target data, by updating batch normalization (BN) layers batch-by-batch. However, these methods face 3 main challenges: 1) estimation performance is dependent on large batch size to estimate BN parameters and statistics, 2) test samples need to be class-balanced which may not be practical in real-world deployment, 3) there is no guarantee self-supervision objectives can correct domain shift without using any target domain label information. For instance, entropy minimization can lead to undesired trivial solutions where all outputs \"collapse\" to one or a few classes.\nMotivated by the problems of test-time adaptation methods, we propose a challenging but practical source-free DA setting by adapting a pre-trained source model using k-shot support from target do- shows existing settings in the DA literature and the proposed setting. Considerations for real-world usage motivates our proposed source-free k-shot setting to address domain shift:\n• Data availability: Our setting helps to protect privacy of the source domains, and has low requirements for target data availability of only k labelled samples per class during adaptation. During testing, test batch can be of any size with no restrictions. • Inference efficiency: Model parameters are not updated at test-time.\n• Accuracy: Our setting is not dependent on test-time data streaming conditions and selfsupervised objectives, and hence enables more reliable and accurate adaptation.\nWe propose a k-shot method to adapt batch normalization (BN) layers of deep source models to address domain shift. As far as we know, our work is the first source-free domain adaptation method with a few-shot setting. Although BN layer modulation has been explored in existing literature, reliably optimizing BN layers with extremely few support samples is a new and challenging problem. Naively optimizing high-dimensional parameters in BN layers risks a severely ill-posed problem caused by data scarcity, and can result in unreliable estimates that easily over-fit to the small support set.\nIn this work, we introduce a new parameterization of BN layers, and approximate the optimal highdimensional target domain BN statistics by a linear combination of spanning vectors representing both source and target domains. Specifically, we linearly combine a small set of spanning vectors obtained from source domain BN statistics and support set, and optimize the combination coefficients by supervised loss on the support set. This significantly reduces the number of parameters to adapt on BN layers. Our proposed method is inspired by the success of controlling sample stylization through BN layers, and we aim to approximate the optimal style to stylize the target domain samples to best address domain shift. We evaluate the proposed method on different image classification benchmark datasets. We provide experimental validations and comparisons with state-of-the-art methods to demonstrate that our approach compares favorably in adaptation accuracy.\nTable 1 shows existing settings in the DA literature and the proposed setting.

        "answer": "A data-driven approach to summarization.",
        "evidence": "The need to access and digest large amounts of textual data has provided strong impetus to develop automatic summarization systems aiming to create shorter versions of one or more documents, whilst preserving their information content. Much effort in automatic summarization has been devoted to sentence extraction, where a summary is created by identifying and subsequently concatenating the most salient text units in a document.\nMost extractive methods to date identify sentences based on human-engineered features. These include surface features such as sentence position and length BIBREF0 , the words in the title, the presence of proper nouns, content features such as word frequency BIBREF1 , and event features such as action nouns BIBREF2 . Sentences are typically assigned a score indicating the strength of presence of these features. Several methods have been used in order to select the summary sentences ranging from binary classifiers BIBREF3 , to hidden Markov models BIBREF4 , graph-based algorithms BIBREF5 , BIBREF6 , and integer linear programming BIBREF7 .\nIn this work we propose a data-driven approach to summarization based on neural networks and continuous sentence features. There has been a surge of interest recently in repurposing sequence transduction neural network architectures for NLP tasks such as machine translation BIBREF8 , question answering BIBREF9 , and sentence compression BIBREF10 . Central to these approaches is an encoder-decoder architecture modeled by recurrent neural networks. The encoder reads the source sequence into a list of continuous-space representations from which the decoder generates the target sequence. An attention mechanism BIBREF11 is often used to locate the region of focus during decoding.\nWe develop a general framework for single-document summarization which can be used to extract sentences or words. Our model includes a neural network-based hierarchical document reader or encoder and an attention-based content extractor. The role of the reader is to derive the meaning representation of a document based on its sentences and their constituent words. Our models adopt a variant of neural attention to extract sentences or words. Contrary to previous work where attention is an intermediate step used to blend hidden units of an encoder to a vector propagating additional information to the decoder, our model applies attention directly to select sentences or words of the input document as the output summary. Similar neural attention architectures have been previously used for geometry reasoning BIBREF12 , under the name Pointer Networks.\nOne stumbling block to applying neural network models to extractive summarization is the lack of training data, i.e., documents with sentences (and words) labeled as summary-worthy. Inspired by previous work on summarization BIBREF7 , BIBREF13 and reading comprehension BIBREF9 we retrieve hundreds of thousands of news articles and corresponding highlights from the DailyMail website. Highlights usually appear as bullet points giving a brief overview of the information contained in the article (see Figure 1 for an example). Using a number of transformation and scoring algorithms, we are able to match highlights to document content and construct two large scale training datasets, one for sentence extraction and the other for word extraction. Previous approaches have used small scale training data in the range of a few hundred examples.\nOur work touches on several strands of research within summarization and neural sequence modeling. The idea of creating a summary by extracting words from the source document was pioneered in bankoetal00 who view summarization as a problem analogous to statistical machine translation and generate headlines using statistical models for selecting and ordering the summary words. Our word-based model is similar in spirit, however, it operates over continuous representations, produces multi-sentence output, and jointly selects summary words and organizes them into sentences. A few recent studies BIBREF14 , BIBREF15 perform sentence extraction based on pre-trained sentence embeddings following an unsupervised optimization paradigm. Our work also uses continuous representations to express the meaning of sentences and documents, but importantly employs neural networks more directly to perform the actual summarization task.\nrush2015neural propose a neural attention model for abstractive sentence compression which is trained on pairs of headlines and first sentences in an article. In contrast, our model summarizes documents rather than individual sentences, producing multi-sentential discourse. A major architectural difference is that our decoder selects output symbols from the document of interest rather than the entire vocabulary. This effectively helps us sidestep the difficulty of searching for the next output symbol under a large vocabulary, with low-frequency words and named entities whose representations can be challenging to learn. Gu:ea:16 and gulcehre2016pointing propose a similar “copy” mechanism in sentence compression and other tasks; their model can accommodate both generation and extraction by selecting which sub-sequences in the input sequence to copy in the output.\nWe evaluate our models both automatically (in terms of Rouge) and by humans on two datasets: the benchmark DUC 2002 document summarization corpus and our own DailyMail news highlights corpus. Experimental results show that our summarizers achieve performance comparable to state-of-the-art systems employing hand-engineered features and sophisticated linguistic constraints.\nIn this work we propose a data-driven approach to summarization based on neural networks and continuous sentence features.",

At the heart of the Transformer lie multi-head attention mechanisms: each word is represented by multiple different weighted averages of its relevant context. As suggested by recent works on interpreting attention head roles, separate attention heads may learn to look for various relationships between tokens BIBREF5, BIBREF6, BIBREF7, BIBREF8, BIBREF9.\nThe attention distribution of each head is predicted typically using the softmax normalizing transform. As a result, all context words have non-zero attention weight. Recent work on single attention architectures suggest that using sparse normalizing transforms in attention mechanisms such as sparsemax – which can yield exactly zero probabilities for irrelevant words – may improve performance and interpretability BIBREF12, BIBREF13, BIBREF14. Qualitative analysis of attention heads BIBREF0 suggests that, depending on what phenomena they capture, heads tend to favor flatter or more peaked distributions.\nRecent works have proposed sparse Transformers BIBREF10 and adaptive span Transformers BIBREF11. However, the “sparsity\" of those models only limits the attention to a contiguous span of past tokens, while in this work we propose a highly adaptive Transformer model that is capable of attending to a sparse set of words that are not necessarily contiguous.

Labeling thousands of hours of audio, however, is expensive and time-consuming. A natural question to ask is how to achieve better generalization with fewer training examples. Active learning studies this problem by identifying and labeling only the most informative data, potentially reducing sample complexity. How much active learning can help in large-scale, end-to-end ASR systems, however, is still an open question.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores. In particular, an utterance is considered informative if the most likely prediction has small probability BIBREF1 , or if the predictions are distributed very uniformly over the labels BIBREF2 . Though confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) BIBREF3 , where the informativeness is measured by the norm of the gradient incurred by the instance. EGL has previously been justified as intuitively measuring the expected change in a model's parameters BIBREF3 .We formalize this intuition from the perspective of asymptotic variance reduction, and experimentally, we show EGL to be superior to confidence-based methods on speech recognition tasks. Additionally, we observe that the ranking of samples scored by EGL is not correlated with that of confidence scoring, suggesting EGL identifies aspects of an instance that confidence scores cannot capture.\nIn BIBREF3 , EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular. Gradient-based methods have also found applications outside active learning. For example, BIBREF4 suggests that in stochastic gradient descent, sampling training instances with probabilities proportional to their gradient lengths can speed up convergence. From the perspective of variance reduction, this importance sampling problem shares many similarities to problems found in active learning.\nwe show EGL to be superior to confidence-based methods on speech recognition tasks.",

One very popular reason is they feel great pride in seeing their children grow into adulthood and take on the responsibility of having children. A second reason grandparents say their role is so special is they get to enjoy their grandchildren, and then return them to their parents who have the ongoing responsibility for raising the children. This creates a special bond between the grandparents and grandchildren that many grandparents describe as special.  A third reason many say it is special to be a grandparent is tied to an instinctive love they describe that they have for their grandchildren. You may hear them say, \"I loved this grandchild from the minute I heard they were conceived, and the love has nothing to do with any merit, just love because they are my grandchild.\"  Having this love for another is a key factor in why it is special to be a grandparent.",

        "evidence": "Story-telling is on the frontier of current text generation technology: stories must remain thematically consistent across the complete document, requiring modeling very long range dependencies; stories require creativity; and stories need a high level plot, necessitating planning ahead rather than word-by-word generation BIBREF0 .\nWe tackle the challenges of story-telling with a hierarchical model, which first generates a sentence called the prompt describing the topic for the story, and then conditions on this prompt when generating the story. Conditioning on the prompt or premise makes it easier to generate consistent stories because they provide grounding for the overall plot. It also reduces the tendency of standard sequence models to drift off topic.\nWe find that standard sequence-to-sequence (seq2seq) models BIBREF1 applied to hierarchical story generation are prone to degenerating into language models that pay little attention to the writing prompt (a problem that has been noted in other domains, such as dialogue response generation BIBREF2 ). This failure is due to the complex and underspecified dependencies between the prompt and the story, which are much harder to model than the closer dependencies required for language modeling (for example, consider the subtle relationship between the first sentence and prompt in Figure FIGREF1 ).\nTo improve the relevance of the generated story to its prompt, we introduce a fusion mechanism BIBREF3 where our model is trained on top of an pre-trained seq2seq model. To improve over the pre-trained model, the second model must focus on the link between the prompt and the story. For the first time, we show that fusion mechanisms can help seq2seq models build dependencies between their input and output.\nAnother major challenge in story generation is the inefficiency of modeling long documents with standard recurrent architectures—stories contain 734 words on average in our dataset. We improve efficiency using a convolutional architecture, allowing whole stories to be encoded in parallel. Existing convolutional architectures only encode a bounded amount of context BIBREF4 , so we introduce a novel gated self-attention mechanism that allows the model to condition on its previous outputs at different time-scales.\nTo train our models, we gathered a large dataset of 303,358 human generated stories paired with writing prompts from an online forum. Evaluating free form text is challenging, so we also introduce new evaluation metrics which isolate different aspects of story generation.\nExperiments show that our fusion and self-attention mechanisms improve over existing techniques on both automated and human evaluation measures. Our new dataset and neural architectures allow for models which can creatively generate longer, more consistent and more fluent passages of text. Human judges prefer our hierarchical model's stories twice as often as those of a non-hierarchical baseline.\nWe find that standard sequence-to-sequence (seq2seq) models applied to hierarchical story generation are prone to degenerating into language models that pay little attention to the writing prompt (a problem that has been noted in other domains, such as dialogue response generation).

        "evidence": "An oil field is an area of accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, an oil field implies that there is economic benefit worthy of commercial attention. Oil fields themselves may extend up to several hundred kilometers across the surface, meaning that extraction efforts can be large and spread out across the area. In addition to extraction equipment, there may be exploratory wells probing the edges to find more reservoir area, pipelines to transport the oil elsewhere, and support facilities.\n\nOil fields can occur anywhere that the geology of the underlying rock allows, meaning that certain fields can be far away from civilization, including at sea. Creating an operation at an oil field can be a logistically complex undertaking, as it involves not only the equipment associated with extraction and transportation, but infrastructure such as roads and housing for workers. This infrastructure has to be designed with the lifespan of the oil field in mind, as production can last many years.

These propaganda types are listed in BIBREF4 and range from those which might be recognisable at the lexical level (e.g. Name_Calling, Repetition), and those which would likely need to incorporate semantic understanding (Red_Herring, Straw_Man).\nFor several example sentences from a sample document annotated with fragment-level classifications (FLC) (Figure FIGREF13). The corresponding sentence-level classification (SLC) labels would indicate that sentences 3, 4, and 7 are 'propaganda' while the the other sentences are `non-propaganda'.\nThe sentence level classification task is an imbalanced binary classification problem that we address using BERT BIBREF0. We use BERTBASE, uncased, which consists of 12 self-attention layers, and returns a 768-dimension vector that representation a sentence. So as to make use of BERT for sentence classification, we include a fully connected layer on top of the BERT self-attention layers, which classifies the sentence embedding provided by BERT into the two classes of interest (propaganda or non-propaganda).\nWe attempt to exploit various data augmentation techniques to address the problem of class imbalance. Table TABREF17 shows the results of our experiments for different data augmentation techniques when, after shuffling the training data, we train the model on 75% of the training data and test it on the remaining 25% of the training data and the development data.\nWe observe that BERT without augmentation consistently outperforms BERT with augmentation in the experiments when the model is trained on 75% of the training data and evaluated on the rest, i.e trained and evaluated on similar data, coming from the same distribution. This is consistent with observations by Wei et al. wei2019eda that contextual word embeddings do not gain from data augmentation. The fact that we shuffle the training data prior to splitting it into training and testing subsets could imply that the model is learning to associate topic words, such as `Mueller', as propaganda. However, when we perform model evaluation using the development set, which is dissimilar to the training, we observe that synonym insertion and word dropping techniques also do not bring performance gains, while random oversampling increases performance over base BERT by 4%. Synonym insertion provides results very similar to base BERT, while random deletion harms model performance producing lower scores. We believe that this could be attributed to the fact that synonym insertion and random word dropping involve the introduction of noise to the data, while oversampling does not. As we are working with natural language data, this type of noise can in fact change the meaning of the sentence. Oversampling on the other hand purely increases the importance of the minority class by repeating training on the unchanged instances.\nSo as to better understand the aspects of oversampling that contribute to these gains, we perform a class-wise performance analysis of BERT with/without oversampling. The results of these experiments (Table TABREF18) show that oversampling increases the overall recall while maintaining precision. This is achieved by significantly improving the recall of the minority class (propaganda) at the cost of the recall of the majority class.\nSo far we have been able to establish that a) the training and test sets are dissimilar, thus requiring us to generalise our model, b) oversampling provides a method of generalisation, and c) oversampling does this while maintaining recall on the minority (and thus more interesting) class.\nGiven this we explore alternative methods of increasing minority class recall without a significant drop in precision. One such method is cost-sensitive classification, which differs from random oversampling in that it provides a more continuous-valued and consistent method of weighting samples of imbalanced training data; for example, random oversampling will inevitably emphasise some training instances at the expense of others. We detail our methods of using cost-sensitive classification in the next section. Further experiments with oversampling might have provided insights into the relationships between these methods, which we leave for future exploration.\nThe Propaganda Techniques Corpus (PTC) dataset for the 2019 Shared Task on Fine-Grained Propaganda consists of a training set of 350 news articles, consisting of just over 16,965 total sentences, in which specifically propagandistic fragments have been manually spotted and labelled by experts. This is accompanied by a development set (or dev set) of 61 articles with 2,235 total sentences, whose labels are maintained by the shared task organisers; and two months after the release of this data, the organisers released a test set of 86 articles and 3,526 total sentences.****Table 2 shows the results of our experi_x001f_ments for different data augmentation techniques when, after shuffling the training data, we train the model on75% of the training data and test it on the remaining 25% of the training data and the devel\u001fopment data.",

        "question": "In what contexts do the authors focus on document quality assessment?",
        "answer": "In two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.",
        "evidence": "The task of document quality assessment is to automatically assess a document according to some predefined inventory of quality labels. This can take many forms, including essay scoring (quality = language quality, coherence, and relevance to a topic), job application filtering (quality = suitability for role + visual/presentational quality of the application), or answer selection in community question answering (quality = actionability + relevance of the answer to the question). In the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.\nAutomatic quality assessment has obvious benefits in terms of time savings and tractability in contexts where the volume of documents is large. In the case of dynamic documents (possibly with multiple authors), such as in the case of Wikipedia, it is particularly pertinent, as any edit potentially has implications for the quality label of that document (and around 10 English Wikipedia documents are edited per second). Furthermore, when the quality assessment task is decentralized (as in the case of Wikipedia and academic paper assessment), quality criteria are often applied inconsistently by different people, where an automatic document quality assessment system could potentially reduce inconsistencies and enable immediate author feedback.\nCurrent studies on document quality assessment mainly focus on textual features. For example, BIBREF0 examine features such as the article length and the number of headings to predict the quality class of a Wikipedia article. In contrast to these studies, in this paper, we propose to combine text features with visual features, based on a visual rendering of the document. Figure 1 illustrates our intuition, relative to Wikipedia articles. Without being able to read the text, we can tell that the article in Figure 1 has higher quality than Figure 1 , as it has a detailed infobox, extensive references, and a variety of images. Based on this intuition, we aim to answer the following question: can we achieve better accuracy on document quality assessment by complementing textual features with visual features?\nOur visual model is based on fine-tuning an Inception V3 model BIBREF1 over visual renderings of documents, while our textual model is based on a hierarchical biLSTM. We further combine the two into a joint model. We perform experiments on two datasets: a Wikipedia dataset novel to this paper, and an arXiv dataset provided by BIBREF2 split into three sub-parts based on subject category. Experimental results on the visual renderings of documents show that implicit quality indicators, such as images and visual layout, can be captured by an image classifier, at a level comparable to a text classifier. When we combine the two models, we achieve state-of-the-art results over 3/4 of our datasets.\nThis paper makes the following contributions:\nAll code and data associated with this research will be released on publication.\nIn the case of this paper, we focus on document quality assessment in two contexts: Wikipedia document quality classification, and whether a paper submitted to a conference was accepted or not.",

        "question": "The authors also propose a new stylistic response generator by what?",
        "answer": "By making proper adaptations to a large-scale pre-trained language model.",
        "evidence": "Most early research on dialogue response generation focused on generating grammatical and contextually relevant responses BIBREF0, BIBREF1, BIBREF2. While promising results have been demonstrated BIBREF3, BIBREF4, syntactically coherent responses alone do not guarantee an engaging and attractive dialogue system. Expressing a unique and consistent speaking style has been shown to be crucial for increasing the user's engagement with dialogue systems BIBREF5. There are various definitions of language style BIBREF6, BIBREF7, BIBREF8, BIBREF9, BIBREF10. In this work, from a purely computational standpoint, we refer to language style as any characteristic style of expression. Hence, our work is in line with previous work on dialogue generation with emotion BIBREF11, BIBREF12, BIBREF13, BIBREF14; response attitude BIBREF15, and speaker personality BIBREF16.\nThe aforementioned approaches explicitly incorporate the language style information into the model configuration either via embeddings or memory modules to control the process of response generation. In our replication experiments, we found that these approaches tend to overemphasise the importance of the language style. As a result, the generated responses tend to be generic and non-informative BIBREF17, but they do express a distinct style; e.g., they generate a generic response: “I am happy to hear that.\" that conveys a `happy' emotion to different queries.\nIn this work, we propose a novel prototype-to-style (PS) framework to tackle the challenge of stylistic dialogue generation. Our motivation is two-fold: (1) Human-written responses are informative and diverse, which could be leveraged as guidance for the generation model; (2) However, the retrieved response is not guaranteed to express the desired language style. Moreover, the quality of the retrieved response varies among different queries due to the instability of the IR system. Therefore, to transform the retrieved result into a relevant and stylistic response, an adequate editing process is necessary.\nAn illustration of the proposed framework is shown in Figure FIGREF2, where a prototype is first extracted from the retrieved response. The stylistic response generator then takes the desired language style and the extracted prototype as additional input to obtain an adequate and stylistic response. The proposed stylistic response generator mainly inherits from the GPT-2 model BIBREF18 which is pre-trained with a large unlabeled text corpus. However, the GPT-2 model does not naturally fit the task of dialogue generation. To this end, we design various adaptations to the model architecture to extend the GPT-2 model to address the task of dialogue generation. Furthermore, in order to control the style of the generated responses, we train the model with a novel style-aware maximum likelihood estimation (MLE) objective that encodes additional style knowledge into the model's parameters. Finally, to mitigate the possible effect that the retrieved response containing irrelevant and inappropriate information with respect to the input query, we adopt a de-noising learning strategy BIBREF19, BIBREF20 to prevent the model from uncritically copying the prototype.\nTo fully evaluate the proposed approach, we conduct extensive experiments on three benchmark datasets. Results of both human and automatic evaluation show that the proposed approach significantly outperforms several strong baselines. In addition, we also conduct an extensive cross-domain experiment to demonstrate that the proposed approach is more robust than such baselines.\nIt should be noted that stylistic dialogue generation is different from the task of text style transfer. Text style transfer aims to rewrite the input sentences such that they possess certain language styles, while rigorously preserving their semantic meaning BIBREF21. On the other hand, stylistic dialogue generation does not aim at preserving the semantic meaning of the input sentences. Instead, it aims at generating sentences that are adequate and relevant responses to the input sentences, while expressing the prespecified language styles.\nIn summary, the contributions of this work are: (1) We propose a novel framework that tackles the challenge of stylistic dialogue generation by leveraging useful information contained in the retrieved responses; (2) We propose a new stylistic response generator by making proper adaptations to a large-scale pre-trained language model. We train our model with a new style-aware learning objective in a de-noising manner. Experiments show that the proposed model outperforms many strong baselines on three benchmark datasets on both in-domain and cross-domain evaluations.\n(2) We propose a new stylistic response generator by making proper adaptations to a large-scale pre-trained language model.",

        "question": "What is Knowledge representation and reasoning (KRR)?",
        "answer": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services.",
        "evidence": "Knowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services. KRR have been applied in many fields including financial regulations, medical diagnosis, laws, and so on. One major obstacle in KRR is the creation of large-scale knowledge bases with high quality. For one thing, this requires the knowledge engineers (KEs) not only to have the background knowledge in a certain domain but have enough skills in knowledge representation as well. Unfortunately, qualified KEs are also in short supply. Therefore, it would be useful to build a tool that allows the domain experts without any background in logic to construct and query the knowledge base simply from text.\nControlled natural languages (CNLs) BIBREF0 were developed as a technology that achieves this goal. CNLs are designed based on natural languages (NLs) but with restricted syntax and interpretation rules that determine the unique meaning of the sentence. Representative CNLs include Attempto Controlled English BIBREF1 and PENG BIBREF2 . Each CNL is developed with a language parser which translates the English sentences into an intermediate structure, discourse representation structure (DRS) BIBREF3 . Based on the DRS structure, the language parsers further translate the DRS into the corresponding logical representations, e.g., Answer Set Programming (ASP) BIBREF4 programs. One main issue with the aforementioned CNLs is that the systems do not provide enough background knowledge to preserve semantic equivalences of sentences that represent the same meaning but are expressed via different linguistic structures. For instance, the sentences Mary buys a car and Mary makes a purchase of a car are translated into different logical representations by the current CNL parsers. As a result, if the user ask a question who is a buyer of a car, these systems will fail to find the answer.\nIn this thesis proposal, I will present KALM BIBREF5 , BIBREF6 , a system for knowledge authoring and question answering. KALM is superior to the current CNL systems in that KALM has a complex frame-semantic parser which can standardize the semantics of the sentences that express the same meaning via different linguistic structures. The frame-semantic parser is built based on FrameNet BIBREF7 and BabelNet BIBREF8 where FrameNet is used to capture the meaning of the sentence and BabelNet BIBREF8 is used to disambiguate the meaning of the extracted entities from the sentence. Experiment results show that KALM achieves superior accuracy in knowledge authoring and question answering as compared to the state-of-the-art systems.\nThe rest parts are organized as follows: Section SECREF2 discusses the related works, Section SECREF3 presents the KALM architecture, Section SECREF4 presents KALM-QA, the question answering part of KALM, Section SECREF5 shows the evaluation results, Section SECREF6 shows the future work beyond the thesis, and Section SECREF7 concludes the paper.\nKnowledge representation and reasoning (KRR) is the process of representing the domain knowledge in formal languages (e.g., SPARQL, Prolog) such that it can be used by expert systems to execute querying and reasoning services.",

        "question": "Is it wrong to split the infinitive?",
        "evidence": "",
        "answer": "First, let's establish the meaning of a split infinitive. In simple terms the infinitive is the grammatical construct in which a verb is preceded by the word 'to': hence, 'to walk', 'to talk', 'to reason'. As a side-note, it's probably worth exploring whether the 'verbification' of nouns is a good thing: personally, I take issue with this and feel that examples such as 'to medal', meaning 'to win a medal at a sporting event', should never have been visited on the English language. But that's another discussion entirely. Returning to the infinitive, the split occurs when another word (usually an adverb) is placed between the word 'to' and its corresponding verb. Probably the most famous split infinitive occurs in the opening sequence of every episode of the classic and original TV show, Star Trek, with the lines:\n\"Space: The final frontier\nThese are the voyages of the Starship, Enterprise;\nIts five year mission:\nto explore strange new worlds;\nto seek out new life and new civilizations;\nto boldly go where no man has gone before.\"\nNote that final line: 'to boldly go'. Never has an infinitive been split so boldly before or since. Those who are grammatical pedants will have shuddered at this every time (and probably ended up preferring Star Wars to Star Trek as a consequence) but through those original seventy-nine episodes and their many repeat showings, the split infinitive has subtly embedded itself in our lexicon. \nSo, to return to the question, is it wrong to split the infinitive? Since language is constantly evolving, influenced by the whims and practices of each generation, the answer must be 'no'. On the whole sentences tend to flow more freely and with greater elan if infinitives aren't split and pesky adverbs are kept in their place either before or after ('to go boldly' or 'boldly to go') but sometimes one has to admit that splitting works, and we should be thankful for the colour that brings to the language we hear daily. Who nowadays wouldn't want to boldly go?",

        "evidence": "Many machine learning models in question answering tasks often involve matching mechanism. For example, in factoid question answering such as SQuAD BIBREF1 , one needs to match between query and corpus in order to find out the most possible fragment as answer. In multiple choice question answering, such as MC Test BIBREF2 , matching mechanism can also help make the correct decision.\nThe easiest way of matching is to calculate the cosine similarity between two vectors. It is generally done by two step: First, encode text into word vectors, sentence vectors or paragraph vectors. Second, simply calculate the cosine similarity between target vectors. This method performs well when applied to word-level matching. However, as for matching between sentences or paragraphs, a single vector is not sufficient to encode all the important information. In order to solve this problem, Wang and Jiang proposed a “compare-aggregate” BIBREF3 framework that performs word-level matching using multiple techniques followed by aggregation with convolutional neural network. In their work, they show that compare-aggregate framework can effectively match two sequences through a wide range.\nAlthough \"compare-aggregate\" matching mechanism performs well on multiple question answering tasks, it has two deficiencies. First, it tends to aggregate passively through the sequence rather than take the importance of each element into account. That is, \"compare aggregate\" model considers all the sequential contents equally. Second, \"compare aggregate\" can only take few neighboring elements into account at the same time because of the limitation of CNN kernel size.\nIn this paper, we propose Query-based Attention CNN (QACNN) to deal with the deficiencies above. First, we add query-based attention mechanism into original \"compare aggregate\" model. Moreover, We re-design the aggregation mechanism in \"compare aggregate\" to a two-staged CNN architecture which comprises word-level aggregation and sentence-level aggregation. In this way, QACNN can efficiently extract features cross sentences.\nOur model consists of three components: 1) The similarity mapping layer which converts the input passage, query and choice into feature representation and perform a similarity operation to each other. 2) The attention-based CNN matching network composed of a two-staged CNN focusing on word-level and sentence-level matching respectively. 3) The prediction layer which makes the final decision.\nThe main contributions of this work are three-fold. First, we introduce a two-staged CNN architecture which integrates information from word-level to sentence-level, and then from sentence-level to passage-level. Second, we introduce attention mechanism into this net. We use specially designed CNN structure and attention mechanism to recognize the pattern of similarity map and eventually identify specific syntactic structure of queries. By transforming passage-query feature into attention maps and applying it to passage-choice matching result, we reasonably give weight to every word in the passage. Lastly, our model reaches 79.99% accuracy on the MovieQA dataset which yields top 1 result on this dataset.\nLastly, our model reaches 79.99% accuracy on the MovieQA dataset which yields top 1 result on this dataset.",

He compares human life to Sisyphus — rolling a giant rock uphill, only for the rock to fall back down after reaching the top — an absurd and meaningless struggle. He suggests that we accept the absurdity of this world and human existence, and instead embrace the present, because “The struggle itself towards the heights is enough to fill a man's heart. One must imagine Sisyphus happy”.\n\nAnd there you have it, what nihilism is all about, why it happens and a few ways to fight against it. Note that this is a very extensive topic and what I covered here is only the tip of the iceberg, I’d suggest reading up more if you're interested. Hope it helped!",

        "evidence": "Natural text generation, as a key task in NLP, has been advanced substantially thanks to the flourish of neural models BIBREF0 , BIBREF1 . Typical frameworks such as sequence-to-sequence (seq2seq) have been applied to various generation tasks, including machine translation BIBREF2 and dialogue generation BIBREF3 . The standard paradigm to train such neural models is maximum likelihood estimation (MLE), which maximizes the log-likelihood of observing each word in the text given the ground-truth proceeding context BIBREF4 .\nAlthough widely used, MLE suffers from the exposure bias problem BIBREF5 , BIBREF6 : during test, the model sequentially predicts the next word conditioned on its previous generated words while during training conditioned on ground-truth words. To tackle this problem, generative adversarial networks (GAN) with reinforcement learning (RL) training approaches have been introduced to text generation tasks BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 , BIBREF13 , where the discriminator is trained to distinguish real and generated text samples to provide reward signals for the generator, and the generator is optimized via policy gradient BIBREF7 .\nHowever, recent studies have shown that potential issues of training GANs on discrete data are more severe than exposure bias BIBREF14 , BIBREF15 . One of the fundamental issues when generating discrete text samples with GANs is training instability. Updating the generator with policy gradient always leads to an unstable training process because it's difficult for the generator to derive positive and stable reward signals from the discriminator even with careful pre-training BIBREF8 . As a result, the generator gets lost due to the high variance of reward signals and the training process may finally collapse BIBREF16 .\nIn this paper, we propose a novel adversarial training framework called Adversarial Reward Augmented Maximum Likelihood (ARAML) to deal with the instability issue of training GANs for text generation. At each iteration of adversarial training, we first train the discriminator to assign higher rewards to real data than to generated samples. Then, inspired by reward augmented maximum likelihood (RAML) BIBREF17 , the generator is updated on the samples acquired from a stationary distribution with maximum likelihood estimation (MLE), weighted by the discriminator's rewards. This stationary distribution is designed to guarantee that training samples are surrounding the real data, thus the exploration space of our generator is indeed restricted by the MLE training objective, resulting in more stable training. Compared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient. Our contributions are mainly as follows:\nCompared to other text GANs with RL training techniques, our framework acquires samples from the stationary distribution rather than the generator's distribution, and uses RAML training paradigm to optimize the generator instead of policy gradient.",

        "question": "What does it mean if a database is ACID compliant?",
        "evidence": "In computer science, ACID (atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.\n\nIn 1983, Andreas Reuter and Theo Härder coined the acronym ACID, building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems.\n\nAccording to Gray and Reuter, the IBM Information Management System supported ACID transactions as early as 1973 (although the acronym was created later).\n\nAtomicity\nMain article: Atomicity (database systems)\nTransactions are often composed of multiple statements. Atomicity guarantees that each transaction is treated as a single \"unit\", which either succeeds completely or fails completely: if any of the statements constituting a transaction fails to complete, the entire transaction fails and the database is left unchanged. An atomic system must guarantee atomicity in each and every situation, including power failures, errors, and crashes. A guarantee of atomicity prevents updates to the database from occurring only partially, which can cause greater problems than rejecting the whole series outright. As a consequence, the transaction cannot be observed to be in progress by another database client. At one moment in time, it has not yet happened, and at the next, it has already occurred in whole (or nothing happened if the transaction was canceled in progress).\n\nConsistency\nMain article: Consistency (database systems)\nConsistency ensures that a transaction can only bring the database from one consistent state to another, preserving database invariants: any data written to the database must be valid according to all defined rules, including constraints, cascades, triggers, and any combination thereof. This prevents database corruption by an illegal transaction. Referential integrity guarantees the primary key–foreign key relationship.\n\nIsolation\nMain article: Isolation (database systems)\nTransactions are often executed concurrently (e.g., multiple transactions reading and writing to a table at the same time). Isolation ensures that concurrent execution of transactions leaves the database in the same state that would have been obtained if the transactions were executed sequentially. Isolation is the main goal of concurrency control; depending on the isolation level used, the effects of an incomplete transaction might not be visible to other transactions.\n\nDurability\nMain article: Durability (database systems)\nDurability guarantees that once a transaction has been committed, it will remain committed even in the case of a system failure (e.g., power outage or crash). This usually means that completed transactions (or their effects) are recorded in non-volatile memory.",
        "answer": "ACID is an acronym that stands for Atomicity, Consistency, Isolation, and Durability.\nAtomicity means that actions occur either entirely or not at all; there is no partial write or situation where only part of an action was completed. For a database, this means that if data was written in a single transaction, that transaction either completes entirely or fails completely with no data left behind in a partial or corrupt state.\nConsistency means that transactions take the state from one valid state to another valid state, with no way to enter an invalid state.\nIsolation means that multiple readers/writers to the same database do not interfere with each other and can proceed without worrying about the effects of another action occurring.\nDurability means that state is preserved across failures and shutdowns, e.g. that state is persisted to permanent storage.",

        "evidence": "After completing his studies at the Baghdad University, he entered the Iraqi Army, where he served shortly as a tank unit commander. In the early 1960, he was made the head of the Polit bureau of the Kurdistan Democratic Party (KDP). When in September 1961, the Kurdish uprising for the rights of the Kurds in northern Iraq was declared against the Baghdad government of Abd al-Karim Qasim, Talabani took charge of the Kirkuk and Silemani battlefronts and organized and led separatist movements in Mawat, Rezan and the Qaradagh regions.\n\nIn March 1962, he led a coordinated offensive that brought about the liberation of the district of Sharbazher from Iraqi government forces. When not engaged in fighting in the early and mid-1960s, Talabani undertook numerous diplomatic missions, representing the Kurdish leadership at meetings in Europe and the Middle East. In 1964, he and the Barzani family had a dispute over the direction of the KDP and Talabani left Iraq and settled in Iran. In Iran he purchased weapons without the knowledge of the Barzanis, following which he was expelled from the KDP in summer 1964.\n\nAfter the March 1970 agreement between the Iraqi government and the Kurdish rebels, Talabani returned to Iraqi Kurdistan, and rejoined the KDP, even though he wouldn't hold an office at the time. The Kurdish separatist movement collapsed in March 1975, after Iran ended their support in exchange for a border agreement with Iraq. This agreement was the 1975 Algiers Agreement, where Iraq gave up claims to the Shatt al-Arab (Arvand Rūd) waterway and Khuzestan, which later became the basis for the Iran–Iraq War. Believing it was time to give a new direction to the Kurdish separatists and to the Kurdish society, Talabani, with a group of Kurdish intellectuals and activists, founded the Kurdish Patriotic Union of Kurdistan (Yekiaiti Nishtimani Kurdistan).\n\nIn 1976, he began organizing an armed campaign for Kurdish independence inside Iraqi Kurdistan. From 1977 onwards, he established the PUK base within Iranian Kurdistan in Nawkhan and another one in Iraqi Kurdistan in Qandil. During the 1980s, Talabani sided with Iran and led a Kurdish struggle from bases inside Iraq until the crackdown against Kurdish separatists from 1987 to 1988. Following the invasion of Kuwait by Iraq in August 1990, he travelled to the United States, in order to offer his services and troops to the United States and raise support for the PUK. But his attempts did not bear the success he expected at the time.\n\nIn 1991, he helped inspire a renewed effort for Kurdish independence. He negotiated a ceasefire with the Iraqi Ba'athist government that saved the lives of many Kurds and worked closely with the United States, United Kingdom, France and other countries to set up the safe haven in Iraqi Kurdistan. In 1992 the Kurdistan Regional Government was founded. He was also supportive of peace negotiations between the Kurdistan Workers' Party and Turkey, and was also present as Abdullah Öcalan announced the ceasefire of the PKK on the 17 March and prolonged it indefinitely on the 16 April 1993.\n\nTalabani pursued a negotiated settlement to the Iraqi Kurdish Civil War, as well as the larger issue of Kurdish rights in the current regional context. He worked closely with other Kurdish politicians as well as the rest of the Iraqi opposition factions. In close coordination with Masoud Barzani, Talabani and the Kurds played a key role as a partner of the U.S. led Coalition in the invasion of Iraq.\n\nTalabani was a member of the Iraqi Governing Council which negotiated the Transitional Administrative Law (TAL), Iraq's interim constitution. The TAL governed all politics in Iraq and the process of writing and adopting the final constitution.",

        "answer": "The novel task enhances entity pages and reduces delay while keeping its pages authoritative.",
        "evidence": "Wikipedia is the largest source of open and collaboratively curated knowledge in the world. Introduced in 2001, it has evolved into a reference work with around 5m pages for the English Wikipedia alone. In addition, entities and event pages are updated quickly via collaborative editing and all edits are encouraged to include source citations, creating a knowledge base which aims at being both timely as well as authoritative. As a result, it has become the preferred source of information consumption about entities and events. Moreso, this knowledge is harvested and utilized in building knowledge bases like YAGO BIBREF0 and DBpedia BIBREF1 , and used in applications like text categorization BIBREF2 , entity disambiguation BIBREF3 , entity ranking BIBREF4 and distant supervision BIBREF5 , BIBREF6 .\nHowever, not all Wikipedia pages referring to entities (entity pages) are comprehensive: relevant information can either be missing or added with a delay. Consider the city of New Orleans and the state of Odisha which were severely affected by cyclones Hurricane Katrina and Odisha Cyclone, respectively. While Katrina finds extensive mention in the entity page for New Orleans, Odisha Cyclone which has 5 times more human casualties (cf. Figure FIGREF2 ) is not mentioned in the page for Odisha. Arguably Katrina and New Orleans are more popular entities, but Odisha Cyclone was also reported extensively in national and international news outlets. This highlights the lack of important facts in trunk and long-tail entity pages, even in the presence of relevant sources. In addition, previous studies have shown that there is an inherent delay or lag when facts are added to entity pages BIBREF7 .\nTo remedy these problems, it is important to identify information sources that contain novel and salient facts to a given entity page. However, not all information sources are equal. The online presence of major news outlets is an authoritative source due to active editorial control and their articles are also a timely container of facts. In addition, their use is in line with current Wikipedia editing practice, as is shown in BIBREF7 that almost 20% of current citations in all entity pages are news articles. We therefore propose news suggestion as a novel task that enhances entity pages and reduces delay while keeping its pages authoritative.\nExisting efforts to populate Wikipedia BIBREF8 start from an entity page and then generate candidate documents about this entity using an external search engine (and then post-process them). However, such an approach lacks in (a) reproducibility since rankings vary with time with obvious bias to recent news (b) maintainability since document acquisition for each entity has to be periodically performed. To this effect, our news suggestion considers a news article as input, and determines if it is valuable for Wikipedia. Specifically, given an input news article INLINEFORM0 and a state of Wikipedia, the news suggestion problem identifies the entities mentioned in INLINEFORM1 whose entity pages can improve upon suggesting INLINEFORM2 . Most of the works on knowledge base acceleration BIBREF9 , BIBREF10 , BIBREF11 , or Wikipedia page generation BIBREF8 rely on high quality input sources which are then utilized to extract textual facts for Wikipedia page population. In this work, we do not suggest snippets or paraphrases but rather entire articles which have a high potential importance for entity pages. These suggested news articles could be consequently used for extraction, summarization or population either manually or automatically – all of which rely on high quality and relevant input sources.\nWe identify four properties of good news recommendations: salience, relative authority, novelty and placement. First, we need to identify the most salient entities in a news article. This is done to avoid pollution of entity pages with only marginally related news. Second, we need to determine whether the news is important to the entity as only the most relevant news should be added to a precise reference work. To do this, we compute the relative authority of all entities in the news article: we call an entity more authoritative than another if it is more popular or noteworthy in the real world. Entities with very high authority have many news items associated with them and only the most relevant of these should be included in Wikipedia whereas for entities of lower authority the threshold for inclusion of a news article will be lower. Third, a good recommendation should be able to identify novel news by minimizing redundancy coming from multiple news articles. Finally, addition of facts is facilitated if the recommendations are fine-grained, i.e., recommendations are made on the section level rather than the page level (placement).\nApproach and Contributions. We propose a two-stage news suggestion approach to entity pages. In the first stage, we determine whether a news article should be suggested for an entity, based on the entity's salience in the news article, its relative authority and the novelty of the article to the entity page. The second stage takes into account the class of the entity for which the news is suggested and constructs section templates from entities of the same class. The generation of such templates has the advantage of suggesting and expanding entity pages that do not have a complete section structure in Wikipedia, explicitly addressing long-tail and trunk entities. Afterwards, based on the constructed template our method determines the best fit for the news article with one of the sections.\nWe evaluate the proposed approach on a news corpus consisting of 351,982 articles crawled from the news external references in Wikipedia from 73,734 entity pages. Given the Wikipedia snapshot at a given year (in our case [2009-2014]), we suggest news articles that might be cited in the coming years. The existing news references in the entity pages along with their reference date act as our ground-truth to evaluate our approach.

        "evidence": "Mushroom power-ups appear in almost every Super Mario game. The most iconic of these is the Super Mushroom. The Super Mushroom increases the character's size, turning them into a \"Super\" variant, and allows them to break certain blocks. When hit by an enemy, the character reverts to their smaller size instead of losing a life. When the character is in their \"Super\" form, most blocks that would contain a Super Mushroom instead offer a more powerful power-up such as the Fire Flower. The Super Mushroom is similar in appearance to the Amanita muscaria, with an ivory stalk below a most commonly red and white (originally red and orange) spotted cap. Created by chance, Shigeru Miyamoto stated in an interview that beta tests of Super Mario Bros. proved Mario too tall, so the development team implemented mushrooms to grow and shrink Mario. Different variants of mushroom power-ups appear in the series. For example, Super Mario Bros.: The Lost Levels introduces the Poison Mushroom, which causes damage when collected; and New Super Mario Bros. introduces the Mini Mushroom, which shrinks the character to miniature size; and the Mega Mushroom, grows the character into a towering, invulnerable giant who destroys enemies and the environment by running through them.\n\nSuper Mario Bros. 3 introduces suits to the Super Mario series, many of which are based on animals or Mario enemies. The Raccoon Suit (provisioned by a Super Leaf) and the Tanooki Suit each provide the character with a tail that enables flight. In addition, the Tanooki Suit lets the character spontaneously change into an invincible statue for about five seconds. Super Mario Bros. 3 includes a Hammer Bros. suit, which allows Mario and Luigi to throw hammers as projectiles to defeat enemies at a distance. Other suits in later games in the series include the Frog Suit, Penguin Suit, Cat Suit, Boomerang Suit, and Bee Suit.",

        "evidence": "Using GANs, we can train generative models in a two-player game setting between a discriminator and a generator, where the discriminator (a binary classifier) learns to distinguish between real and fake data samples and the generator tries to fool the discriminator by generating authentic and high quality output BIBREF16. GANs have shown to be successful in image generation tasks BIBREF17 and recently, some progress has been observed in text generation BIBREF13, BIBREF12, BIBREF15. Our generator is a language model trained using backpropagation through time BIBREF18. During the pre-training phase we optimize for MLE and during the GAN training phase, we optimize on the creativity reward from the discriminator. The discriminator's encoder has the same architecture as the generator encoder module with the addition of a pooled decoder layer. The decoder contains 3 $[Dense Batch Normalization,ReLU]$ blocks and an addtional $Sigmoid$ layer. The discriminator decoder takes the hidden state at the last time step of a sequence concatenated with both the max-pooled and mean-pooled representation of the hidden states BIBREF19 and outputs a number in the range $[0,1]$. The difficulty of using GANs in text generation comes from the discrete nature of text, making the model non-differentiable hence, we update parameters for the generator model with policy gradients as described in Yu BIBREF15.\nWe utilize AWD-LSTM BIBREF20 and TransformerXL BIBREF21 based language models. For model hyperparameters please to refer to Supplementary Section Table TABREF5. We use Adam optimizer BIBREF22 with $\\beta 1= 0.7$ and $\\beta 2= 0.8$ similar to BIBREF19 and use a batch size of 50. Other practices for LM training were the same as BIBREF21 and BIBREF20 for Transformer-XL and AWD-LSTM respectively. We refer to our proposed GAN as Creative-GAN and compare it to a baseline (a language model equivalent to our pre-trained generator) and a GumbelGAN model BIBREF14 across all proposed datasets. We use three creative English datasets with distinct linguistic characteristics: (1) A corpus of 740 classical and contemporary English poems, (2) a corpus of 14950 metaphor sentences retrieved from a metaphor database website and (3) a corpus of 1500 song lyrics ranging across genres. The mix of linguistic styles within this corpus offers the potential for interesting variation during the generation phase. We use the same pre-processing as in earlier work BIBREF19, BIBREF23. We reserve 10% of our data for test set and another 10% for our validation set.\nWe first pre-train our generator on the Gutenberg dataset BIBREF24 for 20 epochs and then fine-tune BIBREF19 them to our target datasets with a language modeling objective. The discriminator's encoder is initialized to the same weights as our fine-tuned language model. Once we have our fine-tuned encoders for each target dataset, we train in an adversarial manner. The discriminator objective here is to score the quality of the creative text. The discriminator is trained for 3 iterations for every iteration of the generator, a practice seen in previous work BIBREF25. Creative-GAN relies on using the reward from the discriminator BIBREF12, BIBREF15 for backpropagation. We follow a similar training procedure for GumbelGAN. Outputs are generated through sampling over a multinomial distribution for all methods, instead of $argmax$ on the log-likelihood probabilities, as sampling has shown to produce better output quality BIBREF4. Please refer to Supplementary Section Table TABREF6 for training parameters of each dataset and Table TABREF5 for hyperparameters of each encoder. We pick these values after experimentation with our validation set. Training and output generation code can be found online.\nWe use three creative English datasets with distinct linguistic characteristics: (1) A corpus of 740 classical and contemporary English poems, (2) a corpus of 14950 metaphor sentences retrieved from a metaphor database website 1 and (3) a corpus of 1500 song lyrics ranging across genres.",

        "question": "Extract references to electric fish in ancient texts from the following passage.",
        "evidence": "Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the \"Thunderer of the Nile\", and described them as the \"protectors\" of all other fish. Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by electric catfish and electric rays, and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them.\nAncient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.\nThales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature.\nElectricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the New Latin word electricus (\"of amber\" or \"like amber\",, elektron, the Greek word for \"amber\") to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words \"electric\" and \"electricity\", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646.\nFurther work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges\nIn 1775, Hugh Williamson reported a series of experiments to the Royal Society on the shocks delivered by the electric eel; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his \"On Physical Lines of Force\" in 1861 and 1862. \nWhile the early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering. Through such people as Alexander Graham Bell, Ottó Bláthy, Thomas Edison, Galileo Ferraris, Oliver Heaviside, Ányos Jedlik, William Thomson, 1st Baron Kelvin, Charles Algernon Parsons, Werner von Siemens, Joseph Swan, Reginald Fessenden, Nikola Tesla and George Westinghouse, electricity turned from a scientific curiosity into an essential tool for modern life.\nIn 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for \"his discovery of the law of the photoelectric effect\". The photoelectric effect is also employed in photocells such as can be found in solar panels.\nThe first solid-state device was the \"cat's-whisker detector\" first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with a solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. These charges and holes are understood in terms of quantum physics. The building material is most often a crystalline semiconductor.\nSolid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium-based point-contact transistor, was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948.",

        "question": "What mechanism does the transformer encoder design to explore the high parallelizability of attention?",
        "answer": "A multi-head attention mechanism based on the scaled dot-product attention.",
        "evidence": "Shared-private feature extractor is mainly used for extracting shared features and private features among different tasks. In this paper, we apply the encoder module of transformer BIBREF16 (henceforth, transformer encoder) to the shared-private extractor of our model. Specially, we employ two transformer encoders to encode the input embeddings of the two tasks as their respective private features. A transformer encoder is used to encode simultaneously the input embeddings of the two tasks as shared features of both tasks. This process is illustrated by the shared-private layer of Figure FIGREF6. The red box in the middle denotes the extraction of shared features and the left and right boxes represent the extraction of private features of two tasks. Next, we take the extraction of the private feature of fake news detection as an example to elaborate on the process of transformer encoder.\nThe kernel of transformer encoder is the scaled dot-product attention, which is a special case of attention mechanism. It can be precisely described as follows:\nwhere ${\\rm \\textbf {Q}} \\in \\mathbb {R}^{l \\times (d_p+d_w)}$, ${\\rm \\textbf {K}} \\in \\mathbb {R}^{l \\times (d_p+d_w)}$, and ${\\rm \\textbf {V}} \\in \\mathbb {R}^{l \\times (d_p+d_w)}$ are query matrix, key matrix, and value matrix, respectively. In our setting, the query ${\\rm \\textbf {Q}}$ stems from the inputs itself, i.e., ${\\rm \\textbf {Q}}={\\rm \\textbf {K}}={\\rm \\textbf {V}}={\\rm \\textbf {E}}$.\nTo explore the high parallelizability of attention, transformer encoder designs a multi-head attention mechanism based on the scaled dot-product attention. More concretely, multi-head attention first linearly projects the queries, keys and values $h$ times by using different linear projections. Then $h$ projections perform the scaled dot-product attention in parallel. Finally, these results of attention are concatenated and once again projected to get the new representation. Formally, the multi-head attention can be formulated as follows:\nwhere ${\\rm \\textbf {W}}_i^Q \\in \\mathbb {R}^{(d_p+d_w) \\times d_k}$, ${\\rm \\textbf {W}}_i^K \\in \\mathbb {R}^{(d_p+d_w) \\times d_k}$, ${\\rm \\textbf {W}}_i^V \\in \\mathbb {R}^{(d_p+d_w) \\times d_k}$ are trainable projection parameters. $d_k$ is $(d_p+d_w)/h$, $h$ is the number of heads. In Eq.(DISPLAY_FORM11), ${\\rm \\textbf {W}}^o \\in \\mathbb {R}^{(d_p+d_w) \\times (d_p+d_w)}$ is also trainable parameter.\nTo explore the high parallelizability of attention, transformer encoder designs a multi-head attention mechanism based on the scaled dot-product attention.",

        "question": "Given that preserving human brains for more than a century is fairly uncommon, what do you think was the motivation for preserving Guiteau's brain?",
        "evidence": "James A. Garfield, the 20th president of the United States, was shot at the Baltimore and Potomac Railroad Station in Washington, D.C., at 9:30 am on Saturday, July 2, 1881. He died in Elberon, New Jersey, 79 days later on September 19, 1881. The shooting occurred less than four months into his term as president. Garfield's assassin was Charles J. Guiteau, whose motive was revenge against Garfield for an imagined political debt, and getting Chester A. Arthur elevated to president. Guiteau was convicted of Garfield's murder and executed by hanging one year after the shooting.\n\nPart of Guiteau's preserved brain is on display at the Mütter Museum at the College of Physicians of Philadelphia. Guiteau's bones and more of his brain, along with Garfield's backbone and a few ribs, are kept at the National Museum of Health and Medicine, at the Army's Forest Glen Annex in Silver Spring, Maryland. Garfield's assassination was instrumental to the passage of the Pendleton Civil Service Reform Act on January 16, 1883. Garfield himself had called for civil service reform in his inaugural address and supported it as president in the belief that it would make government more efficient. It was passed as something of a memorial to the fallen President. Arthur lost the Republican nomination in 1884 to Blaine, who went on to lose a close election to Democrat Grover Cleveland.",
        "answer": "One reason for preserving the brain may have been to study structural abnormalities that could have explained Guiteau's violent behavior. Alternatively, because Guiteau was well-known and infamous, his brain may have been preserved for use as a memento or as a warning to discourage presidential assassinations in the future.",

        "evidence": "The SemEval-2010 benchmark dataset BIBREF0 is composed of 244 scientific articles collected from the ACM Digital Library (conference and workshop papers). The input papers ranged from 6 to 8 pages and were converted from PDF format to plain text using an off-the-shelf tool. The only preprocessing applied is a systematic dehyphenation at line breaks and removal of author-assigned keyphrases. Scientific articles were selected from four different research areas as defined in the ACM classification, and were equally distributed into training (144 articles) and test (100 articles) sets. Gold standard keyphrases are composed of both author-assigned keyphrases collected from the original PDF files and reader-assigned keyphrases provided by student annotators.\nLong documents such as those in the SemEval-2010 benchmark dataset are notoriously difficult to handle due to the large number of keyphrase candidates (i.e. phrases that are eligible to be keyphrases) that the systems have to cope with BIBREF6 . Furthermore, noisy textual content, whether due to format conversion errors or to unusable elements (e.g. equations), yield many spurious keyphrase candidates that negatively affect keyphrase extraction performance. This is particularly true for systems that make use of core NLP tools to select candidates, that in turn exhibit poor performance on degraded text. Filtering out irrelevant text is therefore needed for addressing these issues.\nIn this study, we concentrate our effort on re-assessing keyphrase extraction performance on three increasingly sophisticated levels of document preprocessing described below.\nTable shows the average number of sentences and words along with the maximum possible recall for each level of preprocessing. The maximum recall is obtained by computing the fraction of the reference keyphrases that occur in the documents. We observe that the level 2 preprocessing succeeds in eliminating irrelevant text by significantly reducing the number of words (-19%) while maintaining a high maximum recall (-2%). Level 3 preprocessing drastically reduce the number of words to less than a quarter of the original amount while interestingly still preserving high recall.\nLong documents such as those in the SemEval-2010 benchmark dataset are notoriously difficult to handle due to the large number of keyphrase candidates (i.e. phrases that are eligible to be keyphrases) that the systems have to cope with (Hasan and Ng, 2014).

With a line-up comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr, they sparked the \"Beatlemania\" phenomenon in 1963, gained international superstardom in 1964, and remained active until their break-up in 1970. Over the latter half of the decade, they were often viewed as orchestrators of society's developments. Their recognition concerns their effect on the era's youth and counterculture, British identity, popular music's evolution into an art form, and their unprecedented following.\n\nMany cultural movements of the 1960s were assisted or inspired by the Beatles. In Britain, their rise to national prominence signalled the youth-driven changes in postwar society, with respect to social mobility, teenagers' commercial influence, and informality. They spearheaded the shift from American artists' global dominance of rock and roll to British acts (known in the US as the British Invasion) and inspired many young people to pursue music careers. From 1964 to 1970, the group had the top-selling US single one out of every six weeks, and the top-selling US album one out of every three weeks. In 1965, they were awarded MBEs, the first time such an honour was bestowed on a British pop act. A year later, Lennon controversially remarked that the band were \"more popular than Jesus now\".\n\nThe Beatles often incorporated classical elements, traditional pop forms and unconventional recording techniques in innovative ways, especially with the albums Rubber Soul (1965), Revolver (1966) and Sgt. Pepper's Lonely Hearts Club Band (1967). Many of their advances in production, writing, and artistic presentation were soon widespread. Other cultural changes initiated by the group include the elevation of the album to become the dominant form of record consumption over singles, a wider interest in psychedelic drugs and Eastern spirituality, and several fashion trends. The band also pioneered with their record sleeves and music videos, as well as informed music styles such as jangle, folk rock, power pop, psychedelia, progressive rock and heavy metal. By the end of the decade, the group were seen as an embodiment of the era's sociocultural movements, exemplified by the sentiment of their 1967 song \"All You Need Is Love\".\n\nOver the 1960s as a whole, the Beatles were the dominant youth-centred pop act on the sales charts. They broke numerous sales and attendance records, many of which they have or had maintained for decades, and continue to enjoy a canonised status unprecedented for popular musicians. Their songs are among the most recorded in history, with cover versions of \"Yesterday\" exceeding thousands. As of 2009, they were the best-selling band in history, with estimated sales of over 600 million records worldwide. Time included them in its list of the twentieth century's 100 most important people.",

For instance, in the United States between 1973 and 1999, September 16 is the most common birthday and December 25 the least common birthday. Some other uncommon birthdays in the West are January 1, December 24, and April 1.\n\nThe least common birthday is usually a holiday when most people take time off work. There are multiple reasons why these days have fewer births, but one reason is that doctors are less likely to schedule cesarean births on such days. April 1 is an exception, and is likely because parents who are able to choose not to give birth on that day, to prevent their children from being bullied for having their birthday on April Fool's Day.\n\nThis question is harder to answer in many non-Western countries as there is less easily accessible data. For example in a survey of students in India between 2007 and 2012, the statistics show much more births just before school opens, and on round days like the 5th, 10th, 15th, and 20th.

        "evidence": "Single-relation factoid questions are the most common form of questions found in search query logs and community question answering websites BIBREF1 , BIBREF2 . A knowledge-base (KB) such as Freebase, DBpedia, or Wikidata can help answer such questions after users reformulate them as queries. For instance, the question Where was Barack Obama born? can be answered by issuing the following KB query: $\n\\lambda (x).place\\_of\\_birth(Barack\\_Obama, x)\n$ \n However, automatically mapping a natural language question such as Where was Barack Obama born? to its corresponding KB query remains a challenging task.\nThere are three key issues that make learning this mapping non-trivial. First, there are many paraphrases of the same question. Second, many of the KB entries are unseen during training time; however, we still need to correctly predict them at test time. Third, a KB such as Freebase typically contains millions of entities and thousands of predicates, making it difficult for a system to predict these entities at scale BIBREF1 , BIBREF3 , BIBREF0 . In this paper, we address all three of these issues with a character-level encoder-decoder framework that significantly improves performance over state-of-the-art word-level neural models, while also providing a much more compact model that can be learned from less data.\nFirst, we use a long short-term memory (LSTM) BIBREF4 encoder to embed the question. Second, to make our model robust to unseen KB entries, we extract embeddings for questions, predicates and entities purely from their character-level representations. Character-level modeling has been previously shown to generalize well to new words not seen during training BIBREF5 , BIBREF6 , which makes it ideal for this task. Third, to scale our model to handle the millions of entities and thousands of predicates in the KB, instead of using a large output layer in the decoder to directly predict the entity and predicate, we use a general interaction function between the question embeddings and KB embeddings that measures their semantic relevance to determine the output. The combined use of character-level modeling and a semantic relevance function allows us to successfully produce likelihood scores for the KB entries that are not present in our vocabulary, a challenging task for standard encoder-decoder frameworks.\nOur novel, character-level encoder-decoder model is compact, requires significantly less data to train than previous work, and is able to generalize well to unseen entities in test time. In particular, without use of ensembles, we achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% BIBREF0 by 8.2% and 6.4% respectively. Moreover, we only use the training questions provided in SimpleQuestions to train our model, which cover about 24% of words in entity aliases on the test set. This demonstrates the robustness of the character-level model to unseen entities. In contrast, data augmentation is usually necessary to provide more coverage for unseen entities and predicates, as done in previous work BIBREF0 , BIBREF1 .\nIn particular, without use of ensembles, the authors achieve 70.9% accuracy in the Freebase2M setting and 70.3% accuracy in the Freebase5M setting on the SimpleQuestions dataset, outperforming the previous state-of-arts of 62.7% and 63.9% by 8.2% and 6.4% respectively.",

When fine-tuning all the parameters, the model achieves the best score for English QG, but it suffers a performance drop when evaluating on Chinese QG. We find that fine-tuning decoder hurts cross-lingual decoding, and the model learns to only decodes English words. For only fine-tuning decoder, the performance degrades by a large margin for both languages because of the underfitting issue, which indicates the necessity of fine-tuning encoder.\nWe examine whether low-resource NLG can benefit from cross-lingual transfer. We consider English as the rich-resource language, and conduct experiments for few-shot French/Chinese AS.

        "evidence": "Words with multiple senses commonly exist in many languages. For example, the word bank can either mean a “financial establishment” or “the land alongside or sloping down to a river or lake”, based on different contexts. Such a word is called a “polyseme”. The task to identify the meaning of a polyseme in its surrounding context is called word sense disambiguation (WSD). Word sense disambiguation is a long-standing problem in natural language processing (NLP), and has broad applications in other NLP problems such as machine translation BIBREF0 . Lexical sample task and all-word task are the two main branches of WSD problem. The former focuses on only a pre-selected set of polysemes whereas the later intends to disambiguate every polyseme in the entire text. Numerous works have been devoted in WSD task, including supervised, unsupervised, semi-supervised and knowledge based learning BIBREF1 . Our work focuses on using supervised learning to solve all-word WSD problem.\nMost supervised approaches focus on extracting features from words in the context. Early approaches mostly depend on hand-crafted features. For example, IMS by BIBREF2 uses POS tags, surrounding words and collections of local words as features. These approaches are later improved by combining with word embedding features BIBREF0 , which better represents the words' semantic information in a real-value space. However, these methods neglect the valuable positional information between the words in the sequence BIBREF3 . The bi-directional Long-Short-Term-Memory (LSTM) approach by BIBREF3 provides one way to leverage the order of words. Recently, BIBREF4 improved the performance by pre-training a LSTM language model with a large unlabelled corpus, and using this model to generate sense vectors for further WSD predictions. However, LSTM significantly increases the computational complexity during the training process.\nThe development of the so called “fixed-size ordinally forgetting encoding” (FOFE) has enabled us to consider more efficient method. As firstly proposed in BIBREF5 , FOFE provides a way to encode the entire sequence of words of variable length into an almost unique fixed-size representation, while also retain the positional information for words in the sequence. FOFE has been applied to several NLP problems in the past, such as language model BIBREF5 , named entity recognition BIBREF6 , and word embedding BIBREF7 . The promising results demonstrated by the FOFE approach in these areas inspired us to apply FOFE in solving the WSD problem. In this paper, we will first describe how FOFE is used to encode sequence of any length into a fixed-size representation. Next, we elaborate on how a pseudo language model is trained with the FOFE encoding from unlabelled data for the purpose of context abstraction, and how a classifier for each polyseme is built from context abstractions of its labelled training data. Lastly, we provide the experiment results of our method on several WSD data sets to justify the equivalent performance as the state-of-the-art approach.\nWe observe that combining different auxiliary penalty terms results in the best performance, outperforming benchmark methods that require source data.",

A quality of philodendrons is that they do not have a single type of leaf on the same plant. Instead, they have juvenile leaves and adult leaves, which can be drastically different from one another. The leaves of seedling philodendrons are usually heart-shaped early in the life of the plant. But after it has matured past the seedling stage, the leaves will acquire the typical juvenile leaf's shape and size. Later in the philodendron's life, it starts producing adult leaves, a process called metamorphosis. Most philodendrons go through metamorphosis gradually; there is no immediately distinct difference between juvenile and adult leaves. Aside from being typically much bigger than the juvenile leaves, the shape of adult leaves can be significantly different. In fact, considerable taxonomic difficulty has occurred in the past due to these differences, causing juvenile and adult plants to mistakenly be classified as different species.",

The remaining training samples only contribute to computing the ATE estimators on each leaf node of the tree at the prediction stage. There is no intersection between the two subsets. This principle is vital in two aspects. On the one hand, it deals with overfitting and thereby achieving bias reduction. On the other side, it leads to the convergence of the estimator.",
        "evidence": "A growing amount of literature has been devoted to address the problem of HTE estimation with continuous treatments. The algorithms in the context of DRF include methods targeting at confounding bias, kernel-based or ML-based methods for regression bias reduction, and techniques of DRE or DML that balance the trade-off between the two biases. DRF combined with IPW can achieve consistent estimators by weighting the estimation with probability density of treatment. For the regression bias, employ parametric estimations and model DRF as non-parametric functions using kernel regression. To advance, propose a doubly robust estimators for DRF by combine the estimation of generalized propensity score with the estimation of outcome using kernel regression. Thus far, these approaches only provide global estimations and cannot handle massive amounts of high-dimensional data.\nRecently, the great efficiency of ML methods motivates their generalization to the problem of HTE estimation. Towards that end, estimating DRF with ML-based algorithms is developed and among which tree-based models are a great candidate since it partitions the feature space for dimensionality reduction and maximizes the heterogeneity as well. Causal Forest (CF) proposed in utilizes a subset of training samples for growing trees by recursively partitioning via a splitting criterion. Then HTE estimation is given by weighted average over the outcomes of the remaining training samples, known as honesty principle. The final estimator obtained from CF further exhibits a lower degree of bias by tree ensembles. However, their splitting criterion relies on a linear model assumption and is formulated as the difference between the slopes of linear models. The same limitation applies to Orthogonal Random Forest and Bayesian Additive Regression Tress. Nevertheless, the complexity of HTE estimation may not be fully captured by linear or general parametric models, which brings the necessity of non-parametric ML models.\nKernel-based DML estimates the nuisance functions with cross-fitting, constructs a non-parametric DML estimator by Gaeutax Derivative. This motivates the utilization of DML and non-parametric estimation in our work, though it only provide global estimators with the limited capacity of localization. A fully non-parametric DML with locally weighted estimations for continuous treatments has not been considered yet.\nBuilding on prior art, we point out that our integration of DRF estimation into CF overcome the challenges aforementioned by using local non-parametric DRF to constructing splitting criterion. We introduce the conceptual partial DRF as a component of the splitting criterion and employ the distance in the functional space of Partial DRF as a proxy for heterogeneity instead of the difference of slopes. Moreover, the partial DRF can be estimated precisely by the robust kernel-based DML estimators in our splitting criterion.\nThen HTE estimation is given by weighted average over the outcomes of the remaining training samples, known as honesty principle.",

        "evidence": "Lyft was launched in the summer of 2012 by computer programmers Logan Green and John Zimmer as a service of Zimride, a long-distance intercity carpooling company focused on college transport that they founded in 2007 after Green shared rides from the University of California, Santa Barbara campus to visit his girlfriend in Los Angeles and was seeking an easier way to share rides.\n\nIn May 2013, the company made the decision to change its name from Zimride to Lyft. Later that year, Lyft sold the original Zimride service to Enterprise Holdings, the parent company of Enterprise Rent-A-Car, to enable the company to focus exclusively on the growth of Lyft.\n\nLyft's marketing strategy included large pink furry mustaches that drivers attached to the front of their cars and encouraging riders to sit in the front seat and fist bump with drivers upon meeting. In November 2014, the company distanced itself from the fist bump. In January 2015, Lyft introduced a small, glowing plastic dashboard mustache it called a \"glowstache\" as an alternative to the large fuzzy mustaches on the front of cars. The transition was to help overcome the resistance of some riders to arrive at destinations, such as business meetings, in a car with a giant mustache.\n\nIn April 2014, Lyft hired two lobbying firms, TwinLogic Strategies, and Jochum Shore & Trossevin, to address the regulatory barriers and opposition it had received since its launch. Due to regulatory hurdles in New York City, the company altered its business model when establishing Lyft on the East Coast of the United States. Lyft's launch in New York City occurred on the evening of July 25, 2014, and, by the Taxi and Limousine Commission (TLC) and the approval of the Manhattan Supreme Court, only drivers registered with the TLC were permitted to drive Lyft-branded vehicles in New York City.\n\nIn August 2014, the company introduced a shared ride concept, which provides cheaper fares.\n\nIn December 2017, Lyft expanded into Canada, with operations in the Toronto, Hamilton and Ottawa metropolitan areas.\n\nIn March 2018, Lyft partnered with Allscripts to create a platform allowing healthcare providers to arrange rides for patients who lack transportation to appointments. The service would be available to 2,500 hospitals, 180,000 physicians, and approximately 7 million patients. Lyft acquired Motivate, a bicycle-sharing system and the operator of Capital Bikeshare and Citi Bike, in November 2018. The company also announced plans to add 28,000 Citi Bikes and expand its service.\n\nIn March 2019, Lyft became a public company via an initial public offering, raising $2.34 billion at a valuation of $24.3 billion. The company set aside some shares to be given to long-time drivers.\n\nIn March 2020, Lyft acquired Halo Cars which pays drivers to display digital advertisements on their vehicles. In April 2020, Lyft laid off 982 employees and furloughed an additional 288 to reduce operating expenses and adjust cash flows due to the COVID-19 pandemic in the United States. The company continued to offer scooters for rent in San Francisco, while Miami government asked Lyft to halt operations.\n\nIn August 2020, Lyft partnered with rental car company Sixt to let users access rental cars. Most of the rental cars are owned and operated by Sixt, with 85 locations in the US. Lyft receives commissions from rentals.\n\nIn December 2020, Lyft announced plans to launch a multi-city U.S. robotaxi service in 2023 with Motional. Lyft sold its self-driving car division to Toyota for $550 million in April 2021. The division had partnerships with General Motors, NuTonomy, Ford Motor Company, GoMentum Station, and Magna International. It also owned Blue Vision Labs, a London-based augmented reality startup, acquired in 2018 for $72 million.\n\nIn April 2022, Lyft announced an agreement to acquire PBSC Urban Solutions, a Canadian bike-share equipment and technology supplier. In November 2022, the company announced layoffs of approximately 700 employees, or about 13% of its staff.\n\nIn March 2023, amid \"a battered stock price,\" Lyft announced David Risher as its next CEO.

        "answer": "Because it requires a deep understanding of the text that conveys an emotions.",
        "evidence": "With the rapid growth of social network platforms, more and more people tend to share their experiences and emotions online.[2]Corresponding Author: xuruifeng@hit.edu.cn Emotion analysis of online text becomes a new challenge in Natural Language Processing (NLP). In recent years, studies in emotion analysis largely focus on emotion classification including detection of writers' emotions BIBREF0 as well as readers' emotions BIBREF1 . There are also some information extraction tasks defined in emotion analysis BIBREF2 , BIBREF3 , such as extracting the feeler of an emotion BIBREF4 . These methods assume that emotion expressions are already observed. Sometimes, however, we care more about the stimuli, or the cause of an emotion. For instance, Samsung wants to know why people love or hate Note 7 rather than the distribution of different emotions.\nEx.1 我的手机昨天丢了，我现在很难过。\nEx.1 Because I lost my phone yesterday, I feel sad now.\nIn an example shown above, “sad” is an emotion word, and the cause of “sad” is “I lost my phone”. The emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.\nExisting approaches to emotion cause extraction mostly rely on methods typically used in information extraction, such as rule based template matching, sequence labeling and classification based methods. Most of them use linguistic rules or lexicon features, but do not consider the semantic information and ignore the relation between the emotion word and emotion cause. In this paper, we present a new method for emotion cause extraction. We consider emotion cause extraction as a question answering (QA) task. Given a text containing the description of an event which [id=lq]may or may not cause a certain emotion, we take [id=lq]an emotion word [id=lq]in context, such as “sad”, as a query. The question to the QA system is: “Does the described event cause the emotion of sadness?”. The [id=lq]expected answer [id=lq]is either “yes” or “no”. (see Figure FIGREF1 ). We build our QA system based on a deep memory network. The memory network has two inputs: a piece of text, [id=lq]referred to as a story in QA systems, and a query. The [id=lq]story is represented using a sequence of word embeddings.\n[id=lq]A recurrent structure is implemented to mine the deep relation between a query and a text. It measure[id=lq]s the [id=lq]importance of each word in the text by [id=lq]an attention mechanism. Based on the [id=lq]learned attention result, the network maps the text into a low dimensional vector space. This vector is [id=lq]then used to generate an answer. Existing memory network based approaches to QA use weighted sum of attentions to jointly consider short text segments stored in memory. However, they do not explicitly model [id=lq]sequential information in the context. In this paper, we propose a new deep memory network architecture to model the context of each word simultaneously by multiple memory slots which capture sequential information using convolutional operations BIBREF5 , and achieves the state-of-the-art performance compared to existing methods which use manual rules, common sense knowledge bases or other machine learning models.\nThe rest of the paper is organized as follows. Section SECREF2 gives a review of related works on emotion analysis. Section SECREF3 presents our proposed deep memory network based model for emotion cause extraction. Section SECREF4 discusses evaluation results. Finally, Section SECREF5 concludes the work and outlines the future directions.\nThe emotion cause extraction task aims to identify the reason behind an emotion expression. It is a more difficult task compared to emotion classification since it requires a deep understanding of the text that conveys an emotions.",

        "evidence": "Data: We evaluate the spell correctors from § \"Robust Word Recognition\" on movie reviews from the Stanford Sentiment Treebank (SST) BIBREF24 . The SST dataset consists of 8544 movie reviews, with a vocabulary of over 16K words. As a background corpus, we use the IMDB movie reviews BIBREF25 , which contain 54K movie reviews, and a vocabulary of over 78K words. The two datasets do not share any reviews in common. The spell-correction models are evaluated on their ability to correct misspellings. The test setting consists of reviews where each word (with length $\\ge 4$ , barring stopwords) is attacked by one of the attack types (from swap, add, drop and keyboard attacks). In the all attack setting, we mix all attacks by randomly choosing one for each word. This most closely resembles a real world attack setting.\nIn addition to our word recognition models, we also compare to After The Deadline (ATD), an open-source spell corrector. We found ATD to be the best freely-available corrector. We refer the reader to BIBREF7 for comparisons of ScRNN to other anonymized commercial spell checkers.\nFor the ScRNN model, we use a single-layer Bi-LSTM with a hidden dimension size of 50. The input representation consists of 198 dimensions, which is thrice the number of unique characters (66) in the vocabulary. We cap the vocabulary size to 10K words, whereas we use the entire vocabulary of 78470 words when we backoff to the background model. For training these networks, we corrupt the movie reviews according to all attack types, i.e., applying one of the 4 attack types to each word, and trying to reconstruct the original words via cross entropy loss.\nWe calculate the word error rates (WER) of each of the models for different attacks and present our findings in Table 2 . Note that ATD incorrectly predicts $11.2$ words for every 100 words (in the `all' setting), whereas, all of the backoff variations of the ScRNN reconstruct better. The most accurate variant involves backing off to the background model, resulting in a low error rate of $6.9\\%$ , leading to the best performance on word recognition. This is a $32\\%$ relative error reduction compared to the vanilla ScRNN model with a pass-through backoff strategy.

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods",

        "answer": "it is less expensive and quantifies interpretability using continuous values rather than binary evaluations",
        "evidence": "In the word embedding literature, the problem of interpretability has been approached via several different routes. For learning sparse, interpretable word representations from co-occurrence variant matrices, BIBREF21 suggested algorithms based on non-negative matrix factorization (NMF) and the resulting representations are called non-negative sparse embeddings (NNSE). To address memory and scale issues of the algorithms in BIBREF21 , BIBREF22 proposed an online method of learning interpretable word embeddings. In both studies, interpretability was evaluated using a word intrusion test introduced in BIBREF20 . The word intrusion test is expensive to apply since it requires manual evaluations by human observers separately for each embedding dimension. As an alternative method to incorporate human judgement, BIBREF23 proposed joint non-negative sparse embedding (JNNSE), where the aim is to combine text-based similarity information among words with brain activity based similarity information to improve interpretability. Yet, this approach still requires labor-intensive collection of neuroimaging data from multiple subjects.\nIn addition to investigating the semantic distribution in the embedding space, a word category dataset can be also used to quantify the interpretability of the word embeddings. In several studies, BIBREF21 , BIBREF22 , BIBREF20 , interpretability is evaluated using the word intrusion test. In the word intrusion test, for each embedding dimension, a word set is generated including the top 5 words in the top ranks and a noisy word (intruder) in the bottom ranks of that dimension. The intruder is selected such that it is in the top ranks of a separate dimension. Then, human editors are asked to determine the intruder word within the generated set. The editors' performances are used to quantify the interpretability of the embedding. Although evaluating interpretability based on human judgements is an effective approach, word intrusion is an expensive method since it requires human effort for each evaluation. Furthermore, the word intrusion test does not quantify the interpretability levels of the embedding dimensions, instead it yields a binary decision as to whether a dimension is interpretable or not. However, using continuous values is more adequate than making binary evaluations since interpretability levels may vary gradually across dimensions.\nThe word intrusion test is expensive to apply since it requires manual evaluations by human observers separately for each embedding dimension.\nFurthermore, the word intrusion test does not quantify the interpretability levels of the embedding dimensions, instead it yields a binary decision as to whether a dimension is interpretable or not.

        "evidence": "Following developing news stories is imperative to making real-time decisions on important political and public safety matters. Given the abundance of media providers and languages, this endeavor is an extremely difficult task. As such, there is a strong demand for automatic clustering of news streams, so that they can be organized into stories or themes for further processing. Performing this task in an online and efficient manner is a challenging problem, not only for newswire, but also for scientific articles, online reviews, forum posts, blogs, and microblogs.\nA key challenge in handling document streams is that the story clusters must be generated on the fly in an online fashion: this requires handling documents one-by-one as they appear in the document stream. In this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes. For example, for news articles, we would want to cluster them into related news stories.\nTo this end, we introduce a system which aggregates news articles into fine-grained story clusters across different languages in a completely online and scalable fashion from a continuous stream. Our clustering approach is part of a larger media monitoring project to solve the problem of monitoring massive text and TV/Radio streams (speech-to-text). In particular, media monitors write intelligence reports about the most relevant events, and being able to search, visualize and explore news clusters assists in gathering more insight about a particular story. Since relevant events may be spawned from any part of the world (and from many multilingual sources), it becomes imperative to cluster news across different languages.\nIn terms of granularity, the type of story clusters we are interested in are the group of articles which, for example : (i) Narrate recent air-strikes in Eastern Ghouta (Syria); (ii) Describe the recent launch of Space X's Falcon Heavy rocket.\nIn this paper, we provide a treatment to the problem of online document clustering, i.e. the task of clustering a stream of documents into themes.",

The results in Figure 7 show that learning rate annealing is essential for stabilizing both midrun and longrun trajectories. The importance of annealing can be understood as follows. If the EBM is being updated with a very low learning rate, then samples from recent EBM snapshots can function as samples from the current EBM. In the case of midrun trajectory, annealing allows the model to robustify trajectories that are approximately as long as the lifetime of a persistent sample between rejuvenation. In the case of longrun learning, annealing allows the burnin samples to approximately reach the model steady-state before they are included in the update bank. This allows the persistent samples in the update bank to function as approximate steady-state samples from the current EBM, leading to proper modeling of probability mass.",

        "evidence": "Neural language models BIBREF0 , BIBREF1 , BIBREF2 have become an essential component in several areas of natural language processing (NLP), such as machine translation, speech recognition and image captioning. They have also become a common benchmarking application in machine learning research on recurrent neural networks (RNN), because producing an accurate probabilistic model of human language is a very challenging task which requires all levels of linguistic analysis, from pragmatics to phonology, to be taken into account.\nA typical language model is trained on text in a single language, and if one needs to model multiple languages the standard solution is to train a separate model for each language. This presupposes large quantities of monolingual data in each of the languages that needs to be covered and each model with its parameters is completely independent of any of the other models.\nWe propose instead to use a single model with real-valued vectors to indicate the language used, and to train this model with a large number of languages. We thus get a language model whose predictive distribution INLINEFORM0 is a continuous function of the language vector INLINEFORM1 , a property that is trivially extended to other neural NLP models. In this paper, we explore the “language space” containing these vectors, and in particular explore what happens when we move beyond the points representing the languages of the training corpus.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models. The second motivation is data sparseness, an issue that heavily influences the reliability of data-driven models. Resources are scarce for most languages in the world (and also for most domains in otherwise well-supported languages), which makes it hard to train reasonable parameters. By combining data from many languages, we hope to mitigate this issue.\nIn contrast to related work, we focus on massively multilingual data sets to cover for the first time a substantial amount of the linguistic diversity in the world in a project related to data-driven language modeling. We do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data. The only supervision that is giving during training is a language identifier as a one-hot encoding. From that and the actual training examples, the system learns dense vector representations for each language included in our data set along with the character-level RNN parameters of the language model itself.\nWe do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data.",

        "evidence": "Data. We build a dataset of Twitter accounts based on two lists annotated in previous works. For the non-factual accounts, we rely on a list of 180 Twitter accounts from BIBREF1. This list was created based on public resources where suspicious Twitter accounts were annotated with the main fake news types (clickbait, propaganda, satire, and hoax). We discard the satire labeled accounts since their intention is not to mislead or deceive. On the other hand, for the factual accounts, we use a list with another 32 Twitter accounts from BIBREF19 that are considered trustworthy by independent third parties. We discard some accounts that publish news in languages other than English (e.g., Russian or Arabic). Moreover, to ensure the quality of the data, we remove the duplicate, media-based, and link-only tweets. For each account, we collect the maximum amount of tweets allowed by Twitter API. Table TABREF13 presents statistics on our dataset.\n\nBaselines. We compare our approach (FacTweet) to the following set of baselines:\n[leftmargin=4mm]\nLR + Bag-of-words: We aggregate the tweets of a feed and we use a bag-of-words representation with a logistic regression (LR) classifier.\nTweet2vec: We use the Bidirectional Gated recurrent neural network model proposed in BIBREF20. We keep the default parameters that were provided with the implementation. To represent the tweets, we use the decoded embedding produced by the model. With this baseline we aim at assessing if the tweets' hashtags may help detecting the non-factual accounts.\nLR + All Features (tweet-level): We extract all our features from each tweet and feed them into a LR classifier. Here, we do not aggregate over tweets and thus view each tweet independently.\nLR + All Features (chunk-level): We concatenate the features' vectors of the tweets in a chunk and feed them into a LR classifier.\nFacTweet (tweet-level): Similar to the FacTweet approach, but at tweet-level; the sequential flow of the tweets is not utilized. We aim at investigating the importance of the sequential flow of tweets.\nTop-$k$ replies, likes, or re-tweets: Some approaches in rumors detection use the number of replies, likes, and re-tweets to detect rumors BIBREF21. Thus, we extract top $k$ replied, liked or re-tweeted tweets from each account to assess the accounts factuality. We tested different $k$ values between 10 tweets to the max number of tweets from each account. Figure FIGREF24 shows the macro-F1 values for different $k$ values. It seems that $k=500$ for the top replied tweets achieves the highest result. Therefore, we consider this as a baseline.\n\nExperimental Setup. We apply a 5 cross-validation on the account's level. For the FacTweet model, we experiment with 25% of the accounts for validation and parameters selection. We use hyperopt library to select the hyper-parameters on the following values: LSTM layer size (16, 32, 64), dropout ($0.0-0.9$), activation function ($relu$, $selu$, $tanh$), optimizer ($sgd$, $adam$, $rmsprop$) with varying the value of the learning rate (1e-1,..,-5), and batch size (4, 8, 16). The validation split is extracted on the class level using stratified sampling: we took a random 25% of the accounts from each class since the dataset is unbalanced. Discarding the classes' size in the splitting process may affect the minority classes (e.g. hoax). For the baselines' classifier, we tested many classifiers and the LR showed the best overall performance.\n\nResults. Table TABREF25 presents the results. We present the results using a chunk size of 20, which was found to be the best size on the held-out data. Figure FIGREF24 shows the results of different chunks sizes. FacTweet performs better than the proposed baselines and obtains the highest macro-F1 value of $0.565$. Our results indicate the importance of taking into account the sequence of the tweets in the accounts' timelines. The sequence of these tweets is better captured by our proposed model sequence-agnostic or non-neural classifiers. Moreover, the results demonstrate that the features at tweet-level do not perform well to detect the Twitter accounts factuality, since they obtain a result near to the majority class ($0.18$). Another finding from our experiments shows that the performance of the Tweet2vec is weak. This demonstrates that tweets' hashtags are not informative to detect non-factual accounts. In Table TABREF25, we present ablation tests so as to quantify the contribution of subset of features. The results indicate that most performance gains come from words embeddings, style, and morality features. Other features (emotion and sentiment) show lower importance: nevertheless, they still improve the overall system performance (on average 0.35% Macro-F$_1$ improvement). These performance figures suggest that non-factual accounts use semantic and stylistic hidden signatures mostly while tweeting news, so as to be able to mislead the readers and behave as reputable (i.e., factual) sources. We leave a more fine-grained, diachronic analysis of semantic and stylistic features – how semantic and stylistic signature evolve across time and change across the accounts' timelines – for future work.\nWe leave a more fine-grained, diachronic analysis of semantic and stylistic features how semantic and stylistic signature evolve across time and change across the accounts' timelines for future work.",

        "evidence": "Observation on loss decrease. To study the convergence of Kernel SGD, we first illustrate the trajectories of training loss in Figure. As shown in the figure, L-BFGS gets stuck at the saddle points or local minimum in the early stage. ESGD helps escape the saddle points but fails to converge to a better loss on the tabular and text data. Kernel SGD reaches the stable point in a small number of epochs while producing the lowest loss in all types of tasks. This indicates that Kernel SGD has the ability to escape the saddle points and can find a better solution in the non-convex problems. Analysis on generalization. Here, we compare our method with second-order optimization to evaluate the generalization performance. The third and fourth columns of Table list the training and test accuracy achieved by the best models of each optimizer. The best model was selected according to the highest validation accuracy. The values of selected learning rates are available in the supplementary material. Our method shows a remarkable generalization performance and can achieve the highest test accuracy on all the tasks. Especially on IMDb, Kernel SGD improves the test accuracy by around 28%. Moreover, Kernel SGD can mitigate overfitting and achieves a stable accuracy, which is demonstrated by the relatively small gaps between the test accuracy and training accuracy and the small variances. Note that we did not adopt pre-processing techniques such as random flipping on the tested data for fair comparison and thus the accuracy in Table may be slightly different from those shown in other studies.\nAnalysis on convergence speed. We tested the convergence speed and recorded the convergence time in the fifth column of Table. Kernel SGD converges up to 30 times faster than second-order optimization baselines. For Cov-tw and IMDb, L-BFGS converges faster because it stops too early with a relatively large loss and underfits the problems as shown in Figure and Table. Kernel SGD takes more epochs to converge to a better loss and thus needs more convergence time.\nAnalysis on memory cost. The memory for the Hessian matrix is represented in the sixth column of Table. We show the size of the whole kernel matrix in Kernel SGD which is an n × m matrix.\nIn L-BFGS and ESGD, the Hessian matrix of neural networks are not explicitly computed. For L-BFGS, we recorded the memory consumption for storing the historical weights and gradients. In ESGD, we recorded the memory of the preconditioning matrix. Kernel SGD uses much smaller memory to store the kernel matrix in larger neural networks such as ResNet-18 and LSTM, for the computation is based on the training instances rather than the weights in the networks.\nSanity check. Although our main aim in this paper is to improve the second-order optimization methods, for a sanity check and for completeness, we further compare Kernel SGD with first-order optimizers which are mini-batch SGD and SGD with momentum (SGD+M). The parameter momentum was set as 0.9 for SGD+M. The results are shown on the last two columns of Table. Our method still outperforms the first-order optimizers in terms of generality on most tasks (i.e., 5 out of 6 tasks in total).

        "question": "To what extent do the degrees of freedom that the recognition model supply to an attacker?",
        "answer": "Few degrees of freedom.",
        "evidence": "Despite the rapid progress of deep learning techniques on diverse supervised learning tasks, these models remain brittle to subtle shifts in the data distribution. Even when the permissible changes are confined to barely-perceptible perturbations, training robust models remains an open challenge. Following the discovery that imperceptible attacks could cause image recognition models to misclassify examples BIBREF0 , a veritable sub-field has emerged in which authors iteratively propose attacks and countermeasures.\nFor all the interest in adversarial computer vision, these attacks are rarely encountered outside of academic research. However, adversarial misspellings constitute a longstanding real-world problem. Spammers continually bombard email servers, subtly misspelling words in efforts to evade spam detection while preserving the emails' intended meaning BIBREF1 , BIBREF2 . As another example, programmatic censorship on the Internet has spurred communities to adopt similar methods to communicate surreptitiously BIBREF3 .\nIn this paper, we focus on adversarially-chosen spelling mistakes in the context of text classification, addressing the following attack types: dropping, adding, and swapping internal characters within words. These perturbations are inspired by psycholinguistic studies BIBREF4 , BIBREF5 which demonstrated that humans can comprehend text altered by jumbling internal characters, provided that the first and last characters of each word remain unperturbed.\nFirst, in experiments addressing both BiLSTM and fine-tuned BERT models, comprising four different input formats: word-only, char-only, word+char, and word-piece BIBREF6 , we demonstrate that an adversary can degrade a classifier's performance to that achieved by random guessing. This requires altering just two characters per sentence. Such modifications might flip words either to a different word in the vocabulary or, more often, to the out-of-vocabulary token UNK. Consequently, adversarial edits can degrade a word-level model by transforming the informative words to UNK. Intuitively, one might suspect that word-piece and character-level models would be less susceptible to spelling attacks as they can make use of the residual word context. However, our experiments demonstrate that character and word-piece models are in fact more vulnerable. We show that this is due to the adversary's effective capacity for finer grained manipulations on these models. While against a word-level model, the adversary is mostly limited to UNK-ing words, against a word-piece or character-level model, each character-level add, drop, or swap produces a distinct input, providing the adversary with a greater set of options.\nSecond, we evaluate first-line techniques including data augmentation and adversarial training, demonstrating that they offer only marginal benefits here, e.g., a BERT model achieving $90.3$ accuracy on a sentiment classification task, is degraded to $64.1$ by an adversarially-chosen 1-character swap in the sentence, which can only be restored to $69.2$ by adversarial training.\nThird (our primary contribution), we propose a task-agnostic defense, attaching a word recognition model that predicts each word in a sentence given a full sequence of (possibly misspelled) inputs. The word recognition model's outputs form the input to a downstream classification model. Our word recognition models build upon the RNN-based semi-character word recognition model due to BIBREF7 . While our word recognizers are trained on domain-specific text from the task at hand, they often predict UNK at test time, owing to the small domain-specific vocabulary. To handle unobserved and rare words, we propose several backoff strategies including falling back on a generic word recognizer trained on a larger corpus. Incorporating our defenses, BERT models subject to 1-character attacks are restored to $88.3$ , $81.1$ , $78.0$ accuracy for swap, drop, add attacks respectively, as compared to $69.2$ , $63.6$ , and $50.0$ for adversarial training\nFourth, we offer a detailed qualitative analysis, demonstrating that a low word error rate alone is insufficient for a word recognizer to confer robustness on the downstream task. Additionally, we find that it is important that the recognition model supply few degrees of freedom to an attacker. We provide a metric to quantify this notion of sensitivity in word recognition models and study its relation to robustness empirically. Models with low sensitivity and word error rate are most robust.\nAdditionally, we find that it is important that the recognition model supply few degrees of freedom to an attacker.",

        "answer": "Yes, they do.",
        "evidence": "Even though machine translation has improved considerably with the advent of neural machine translation (NMT) BIBREF0 , BIBREF1 , the translation of pronouns remains a major issue. They are notoriously hard to translate since they often require context outside the current sentence.\nAs an example, consider the sentences in Figure FIGREF1 . In both languages, there is a pronoun in the second sentence that refers to the European Central Bank. When the second sentence is translated from English to German, the translation of the pronoun it is ambiguous. This ambiguity can only be resolved with context awareness: if a translation system has access to the previous English sentence, the previous German translation, or both, it can determine the antecedent the pronoun refers to. In this German sentence, the antecedent Europäische Zentralbank dictates the feminine gender of the pronoun sie.\nIt is unfortunate, then, that current NMT systems generally operate on the sentence level BIBREF2 , BIBREF3 , BIBREF4 . Documents are translated sentence-by-sentence for practical reasons, such as line-based processing in a pipeline and reduced computational complexity. Furthermore, improvements of larger-context models over baselines in terms of document-level metrics such as BLEU or RIBES have been moderate, so that their computational overhead does not seem justified, and so that it is hard to develop more effective context-aware architectures and empirically validate them.\nTo address this issue, we present an alternative way of evaluating larger-context models on a test set that allows to specifically measure a model's capability to correctly translate pronouns. The test suite consists of pairs of source and target sentences, in combination with contrastive translation variants (for evaluation by model scoring) and additional linguistic and contextual information (for further analysis). The resource is freely available. Additionally, we evaluate several context-aware models that have recently been proposed in the literature on this test set, and extend existing models with parameter tying.\nThe main contributions of our paper are:\nSection SECREF2 explains how our paper relates to existing work on context-aware models and the evaluation of pronoun translation.

        "evidence": "Word Sense Disambiguation (WSD) is a fundamental task and long-standing challenge in Natural Language Processing (NLP), which aims to find the exact sense of an ambiguous word in a particular context BIBREF0. Previous WSD approaches can be grouped into two main categories: knowledge-based and supervised methods.\nKnowledge-based WSD methods rely on lexical resources like WordNet BIBREF1 and usually exploit two kinds of lexical knowledge. The gloss, which defines a word sense meaning, is first utilized in Lesk algorithm BIBREF2 and then widely taken into account in many other approaches BIBREF3, BIBREF4. Besides, structural properties of semantic graphs are mainly used in graph-based algorithms BIBREF5, BIBREF6.\nTraditional supervised WSD methods BIBREF7, BIBREF8, BIBREF9 focus on extracting manually designed features and then train a dedicated classifier (word expert) for every target lemma.\nAlthough word expert supervised WSD methods perform better, they are less flexible than knowledge-based methods in the all-words WSD task BIBREF10. Recent neural-based methods are devoted to dealing with this problem. BIBREF11 present a supervised classifier based on Bi-LSTM, which shares parameters among all word types except the last layer. BIBREF10 convert WSD task to a sequence labeling task, thus building a unified model for all polysemous words. However, neither of them can totally beat the best word expert supervised methods.\nMore recently, BIBREF12 propose to leverage the gloss information from WordNet and model the semantic relationship between the context and gloss in an improved memory network. Similarly, BIBREF13 introduce a (hierarchical) co-attention mechanism to generate co-dependent representations for the context and gloss. Their attempts prove that incorporating gloss knowledge into supervised WSD approach is helpful, but they still have not achieved much improvement, because they may not make full use of gloss knowledge.\nIn this paper, we focus on how to better leverage gloss information in a supervised neural WSD system. Recently, the pre-trained language models, such as ELMo BIBREF14 and BERT BIBREF15, have shown their effectiveness to alleviate the effort of feature engineering. Especially, BERT has achieved excellent results in question answering (QA) and natural language inference (NLI). We construct context-gloss pairs from glosses of all possible senses (in WordNet) of the target word, thus treating WSD task as a sentence-pair classification problem. We fine-tune the pre-trained BERT model and achieve new state-of-the-art results on WSD task. In particular, our contribution is two-fold:\n1. We construct context-gloss pairs and propose three BERT-based models for WSD.\n2. We fine-tune the pre-trained BERT model, and the experimental results on several English all-words WSD benchmark datasets show that our approach significantly outperforms the state-of-the-art systems.\nWord Sense Disambiguation (WSD) is a fundamental task and long-standing challenge in Natural Language Processing (NLP), which aims to find the exact sense of an ambiguous word in a particular context (Navigli, 2009).",

        "question": "What data did the authors explore the novel application of capsule networks (CapsNet) on?",
        "answer": "Triple-based data.",
        "evidence": "Knowledge graphs (KGs) containing relationship triples (subject, relation, object), denoted as (s, r, o), are the useful resources for many NLP and especially information retrieval applications such as semantic search and question answering BIBREF0 . However, large knowledge graphs, even containing billions of triples, are still incomplete, i.e., missing a lot of valid triples BIBREF1 . Therefore, much research efforts have focused on the knowledge graph completion task which aims to predict missing triples in KGs, i.e., predicting whether a triple not in KGs is likely to be valid or not BIBREF2 , BIBREF3 , BIBREF4 . To this end, many embedding models have been proposed to learn vector representations for entities (i.e., subject/head entity and object/tail entity) and relations in KGs, and obtained state-of-the-art results as summarized by BIBREF5 and BIBREF6 . These embedding models score triples (s, r, o), such that valid triples have higher plausibility scores than invalid ones BIBREF2 , BIBREF3 , BIBREF4 . For example, in the context of KGs, the score for (Melbourne, cityOf, Australia) is higher than the score for (Melbourne, cityOf, United Kingdom).\nTriple modeling is applied not only to the KG completion, but also for other tasks which can be formulated as a triple-based prediction problem. An example is in search personalization, one would aim to tailor search results to each specific user based on the user's personal interests and preferences BIBREF7 , BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 , BIBREF12 . Here the triples can be formulated as (submitted query, user profile, returned document) and used to re-rank documents returned to a user given an input query, by employing an existing KG embedding method such as TransE BIBREF3 , as proposed by BIBREF12 . Previous studies have shown the effectiveness of modeling triple for either KG completion or search personalization. However, there has been no single study investigating the performance on both tasks.\nConventional embedding models, such as TransE BIBREF3 , DISTMULT BIBREF13 and ComplEx BIBREF14 , use addition, subtraction or simple multiplication operators, thus only capture the linear relationships between entities. Recent research has raised interest in applying deep neural networks to triple-based prediction problems. For example, BIBREF15 proposed ConvKB—a convolutional neural network (CNN)-based model for KG completion and achieved state-of-the-art results. Most of KG embedding models are constructed to modeling entries at the same dimension of the given triple, where presumably each dimension captures some relation-specific attribute of entities. To the best of our knowledge, however, none of the existing models has a “deep” architecture for modeling the entries in a triple at the same dimension.\n BIBREF16 introduced capsule networks (CapsNet) that employ capsules (i.e., each capsule is a group of neurons) to capture entities in images and then uses a routing process to specify connections from capsules in a layer to those in the next layer. Hence CapsNet could encode the intrinsic spatial relationship between a part and a whole constituting viewpoint invariant knowledge that automatically generalizes to novel viewpoints. Each capsule accounts for capturing variations of an object or object part in the image, which can be efficiently visualized. Our high-level hypothesis is that embedding entries at the same dimension of the triple also have these variations, although it is not straightforward to be visually examined.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization. Different from the traditional modeling design of CapsNet where capsules are constructed by splitting feature maps, we use capsules to model the entries at the same dimension in the entity and relation embeddings. In our CapsE, INLINEFORM0 , INLINEFORM1 and INLINEFORM2 are unique INLINEFORM3 -dimensional embeddings of INLINEFORM4 , INLINEFORM5 and INLINEFORM6 , respectively. The embedding triple [ INLINEFORM7 , INLINEFORM8 , INLINEFORM9 ] of (s, r, o) is fed to the convolution layer where multiple filters of the same INLINEFORM10 shape are repeatedly operated over every row of the matrix to produce INLINEFORM11 -dimensional feature maps. Entries at the same dimension from all feature maps are then encapsulated into a capsule. Thus, each capsule can encode many characteristics in the embedding triple to represent the entries at the corresponding dimension. These capsules are then routed to another capsule which outputs a continuous vector whose length is used as a score for the triple. Finally, this score is used to predict whether the triple (s, r, o) is valid or not.\nIn summary, our main contributions from this paper are as follows:\n INLINEFORM0 We propose an embedding model CapsE using the capsule network BIBREF16 for modeling relationship triples. To our best of knowledge, our work is the first consideration of exploring the capsule network to knowledge graph completion and search personalization.\n INLINEFORM0 We evaluate our CapsE for knowledge graph completion on two benchmark datasets WN18RR BIBREF17 and FB15k-237 BIBREF18 . CapsE obtains the best mean rank on WN18RR and the highest mean reciprocal rank and highest Hits@10 on FB15k-237.\n INLINEFORM0 We restate the prospective strategy of expanding the triple embedding models to improve the ranking quality of the search personalization systems. We adapt our model to search personalization and evaluate on SEARCH17 BIBREF12 – a dataset of the web search query logs. Experimental results show that our CapsE achieves the new state-of-the-art results with significant improvements over strong baselines.\nTo that end, we introduce CapsE to explore a novel application of CapsNet on triple-based data for two problems: KG completion and search personalization.",

He was considered a judges' favorite in Hollywood, with Randy Jackson naming him among his \"top 5\" early favorites. During Hollywood week, he performed \"I Want You Back\" by The Jackson 5 as part of a group called \"White Chocolate\", along with fellow finalist, and future season 8 winner, Kris Allen. He did not make the finals initially, but was brought back for the Wild Card show. The judges unanimously lauded his performance of \"Who's Lovin' You\" by The Miracles (also made famous by The Jackson 5) and he became a part of the Top 13 (along with Anoop Desai, Megan Joy, and Jasmine Murray). Giraud was also the first and only recipient of the new judges' save for his season on April 15, 2009. After his Top 13 performance of \"Human Nature\", Kara DioGuardi remarked \"I hope we see you for many more weeks.\" On Top 11 night, he performed \"So Small\", provoking Simon Cowell to state \"I don't think you've had enough credit in this competition\", and compare him to Michael Bublé. On the night of the Top 8, Giraud sang \"Part-Time Lover\". Paula Abdul kept her compliments short (due to time constraints), simply saying \"Two words: Standing O\". The next week, however, Giraud received poor reviews from Jackson and DioGuardi. The following night, the results revealed that he received the lowest number of votes. However, for the first time in American Idol history, the judges' save was invoked and Giraud was spared elimination when the judges utilized Season 8's new twist. The consequence of this, for all of the contestants, was a double elimination after the second Top 7 night. On that night, Giraud performed \"Stayin' Alive\" and received mixed reviews. Nevertheless, he survived the vote that week and even avoided placing in the Bottom 3. He was eliminated on April 29, 2009 and finished in fifth place. In interviews after his elimination, Giraud says that he believed the \"'Idol' judges' save wasn't a waste\". Giraud was a favorite of Joel Madden.

        "evidence": "The Transformer BIBREF0 is one of the most commonly used neural network architectures in natural language processing. Layer normalization BIBREF1 plays a key role in Transformer's success. The originally designed Transformer places the layer normalization between the residual blocks, which is usually referred to as the Transformer with Post-Layer Normalization (Post-LN) BIBREF2. This architecture has achieved state-of-the-art performance in many tasks including language modeling BIBREF3, BIBREF4 and machine translation BIBREF5, BIBREF6. Unsupervised pre-trained models based on the Post-LN Transformer architecture also show impressive performance in many downstream tasks BIBREF7, BIBREF8, BIBREF9.\nDespite its great success, people usually need to deal with the optimization of the Post-LN Transformer more carefully than convolutional networks or other sequence-to-sequence models BIBREF10. In particular, to train the model from scratch, any gradient-based optimization approach requires a learning rate warm-up stage BIBREF0, BIBREF11: the optimization starts with an extremely small learning rate, and then gradually increases it to a pre-defined maximum value in a pre-defined number of iterations. Such a warm-up stage not only slows down the optimization process but also brings more hyperparameter tunings. BIBREF10 has shown that the final model performance is quite sensitive to the value of the maximum learning rate and the number of warm-up iterations. Tuning such sensitive hyper-parameters is costly in training large-scale models, e.g., BERT BIBREF8 or XLNet BIBREF9.\nIn this paper, we try to alleviate this problem by finding ways to safely remove the learning rate warm-up stage. As the warm-up stage happens in the first several iterations, we investigate the optimization behavior at initialization using mean field theory BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17. According to our theoretical analysis, when putting the layer normalization between the residual blocks, the expected gradients of the parameters near the output layer are large. Therefore, without the warm-up stage, directly using a large learning rate to those parameters can make the optimization process unstable. Using a warm-up stage and training the model with small learning rates practically avoid this problem. Extensive experiments are provided to support our theoretical findings.\nOur theory also shows that the layer normalization plays a crucial role in controlling the gradient scales. This motivates us to investigate whether there are some other ways of positioning the layer normalization that lead to well-behaved gradients. In particular, we study another variant, the Transformer with Pre-Layer Normalization (Pre-LN) BIBREF18, BIBREF19, BIBREF2. The Pre-LN Transformer puts the layer normalization inside the residual connection and equips with an additional final-layer normalization before prediction (Please see Figure SECREF1 for the differences between the two variants of the Transformer architectures). We show that at initialization, the gradients are well-behaved without any exploding or vanishing for the Pre-LN Transformer both theoretically and empirically.\nGiven the gradients are well-behaved in the Pre-LN Transformer, it is natural to consider removing the learning rate warm-up stage during training. We conduct a variety of experiments, including IWSLT14 German-English translation, WMT14 English-German translation, and BERT pre-training tasks. We show that, in all tasks, the learning rate warm-up stage can be safely removed, and thus, the number of hyper-parameter is reduced. Furthermore, we observe that the loss decays faster for the Pre-LN Transformer model. It can achieve comparable final performances but use much less training time. This is particularly important for training large-scale models on large-scale datasets.\nOur contributions are summarized as follows:\n$\\bullet $ We investigate two Transformer variants, the Post-LN Transformer and the Pre-LN Transformer, using mean field theory. By studying the gradients at initialization, we provide evidence to show why the learning rate warm-up stage is essential in training the Post-LN Transformer.\n$\\bullet $ We are the first to show that the learning-rate warm-up stage can be removed for the Pre-LN Transformer, which eases the hyperparameter tuning. We further show that by using proper learning rate schedulers, the training time can be largely reduced on a wide range of applications.\nWe conduct a variety of experiments, including IWSLT14 German-English translation, WMT14 English-German translation, and BERT pre-training tasks.",

        "question": "What frames are used to quantify the amount of agency attributed to a target group?",
        "answer": "Connotation Frames",
        "evidence": "While paragraph-level valence analysis is quick and simple, it is sometimes too coarse because we aim to understand the sentiment directed towards the target group, not just nearby in the text. For example, suppose the target group is named “B\". A sentence such as “A violently attacked B\" would likely have extremely negative valence, but the writer may not feel negatively towards the victim, “B\".\nWe address this by using BIBREF22's Connotation Frames Lexicon, which contains rich annotations for 900 English verbs (BIBREF22). Among other things, for each verb, the Connotation Frames Lexicon provides scores (ranging from -0.87 to 0.8) for the writer's perspective towards the verb's subject and object. In the example above for the verb attack, the lexicon lists the writer's perspective towards the subject “A\", the attacker, as -0.6 (strongly negative) and the object “B\" as 0.23 (weakly positive).\nWe extract all subject-verb-object tuples containing at least one target group label using the Spacy dependency parser . For each subject and object, we capture the noun and the modifying adjectives, as group labels (such as gay) can often take either nominal or adjectival forms. For each tuple, we use the connotation frame lexicon to determine the writer's perspective either towards the subject if the group label appears in the subject noun phrase, or perspective towards the object if the label appears in the object noun phrase. We then average perspective scores over all tuples.\nAs in Section SECREF6, we use Connotation Frames to quantify the amount of agency attributed to a target group. We use BIBREF25's extension of Connotation Frames for agency BIBREF25. Following BIBREF25's interpretation, entities with high agency exert a high degree of control over their own decisions and are active decision-makers, while entities with low agency are more passive BIBREF25. This contrast is particularly apparent in example sentences such as X searched for Y and X waited for Y, where the verb searched gives X high agency and waited gives X low agency BIBREF25. Additionally, BIBREF25's released lexicon for agency indicates that the subjects of verbs such as attack and praise are given high agency, while the subjects of doubts, needs, and owes are given low agency BIBREF25.\nThis lexicon considers the agency attributed to subjects of nearly 2000 transitive and intransitive verbs. To use this lexicon to quantify denial of agency in our corpus, we extract all sentences' head verbs and their corresponding subjects, where the subject noun phrase contains a target group label. Unlike BIBREF22's real-valued Connotation Frames lexicon for perspective, the agency lexicon only provides binary labels, so we calculate the fraction of subject-verb pairs where a subject containing a group label was given high agency by its head verb.\nFigure FIGREF34 shows the writer's average perspective (valence) towards noun phrases containing either any LGBTQ labels, gay(s), homosexual(s), or the comparison group American(s) using the Connotation Frames lexicon BIBREF22. Note that the wide variation, particularly for homosexual, is likely due to sparsity, as limiting the connotation frames analysis to verbs' immediate subject and direct object noun phrase dependents (consisting of only determiners, adjectives, and nouns) greatly reduced the amount of data for each year. For example, there were only 39 triples for homosexual in 2015. We thus show results aggregated over five-year intervals, as in Figure FIGREF27.\nAs with paragraph-level valence, the writer's perspective towards the label homosexual is significantly more negative than towards gay ($ p < 0.001$). Linear regression indicates that perspectives towards noun phrases named by any LGBTQ term, gay, and American have all significantly increased over time ($p < 0.01$). However, the trends are still quite different, as the slopes for gay and all LGBTQ terms are an order of magnitude greater than American ($m =(1.1\\pm 0.39)\\times 10^{-4}$ for American, $m=(1.4\\pm 0.18)\\times 10^{-3}$ for all LGBTQ terms, and $m=(1.1\\pm 0.22)\\times 10^{-3}$ for gay). Furthermore, the writer's perspective towards noun phrases containing homosexual have significantly decreased over time ($p < 0.0001$).\nOverall, connotation frames' perspective scores reveal a similar pattern as the paragraph-level valence analysis, where LGBTQ groups overall appear to be more positively evaluated in the New York Times over time. Unlike gay and the aggregated all LGBTQ terms, the label homosexual undergoes pejoration, as homosexual becomes increasingly used when (implicitly) expressing negative attitudes towards LGBTQ people.\nTo qualitatively analyze how well the connotation frames' lexicon capture the negative evaluation of a target group component of dehumanization, we identify subject-verb-object tuples where the verb indicates that the writer has extremely positive or negative perspective towards either the subject or object. The first two paragraphs in Table TABREF36 were identified among those with the most negative writers' perspectives towards phrases containing LGBTQ labels. The first paragraph (within a quote) uses the phrase any homosexual act as the direct object to the verb committed, which has the effect of framing homosexuality as a crime or other illicit activity. By deeming gay candidates unworthy of the priesthood, the speaker clearly negatively evaluates LGBTQ people. On the opposite end, many of the paragraphs labeled by our method as containing extremely positive perspectives towards phrases containing LGBTQ labels do appear to have positive evaluations of these groups. The second and third paragraphs of Table TABREF36 illustrate this, where the gays are viewed positively for having saved a town, and gay rights advocates are praised for their work.\nHowever, we found several instances where paragraphs seem to have been mislabeled, which are shown in Table TABREF37. In the first paragraph of Table TABREF37, our technique identifies gay marriage as the subject of dependent of the negative-perspective verb harmed, but does not account for the preceding text, which actually reveals that the paragraph contradicts the premise that gay marriage causes harm, and thus does not contain overtly negative evaluations of LGBTQ groups (although this particular example reveals the difficulty of operationalizing this component because ProtectMarriage groups strongly oppose same-sex marriage and may itself have negative evaluations of LGBTQ people). The second example similarly shows that this simple method does not adequately account for various forms of negation, as the positive-perspective verb protect is actually negated. The last example in Table TABREF37 presents a complex case, and it is even qualitatively challenging to determine the writer's perspective towards LGBTQ people. Our method identifies gays as the subject of the verb strengthen, even though the subject should be the gerund allowing gays (into the military), and the lexicon's entry for the writer's perspective towards the subject of of strengthen is a highly positive 0.7. However, the object of this verb is the terrorist organization Al Qaeda; our background knowledge suggests that the capacity to strengthen Al Qaeda would reflect negative perspectives. However, this additional context provided by the rest of the paragraph indicates that the writer is being sarcastic and considers the proposition that gays have any impact on strengthening Al Qaeda to be ridiculous. Finally, the writer emphasizes their own stance in opposition to the Missouri congressional candidate by calling upon common stereotypes of gay people being good at dancing and accessorizing.\nMeasuring the connotation frames' lexicon perspective scores over verbs' subjects and direct objects cannot leverage as much context or data as measuring valence over paragraphs using the NRC VAD lexicon labeled for 20,000 words. However, this technique can make more fine-grained distinctions regarding the writer's (and institution's) attitudes directed towards LGBTQ people and is not as dramatically impacted by the emotional valence of the topic discussed. However, with both techniques presented, we have difficulties disentangling the journalist's perspective from those expressed by others and simply reported by the journalist. While removing direct quotations may partially address this issue, we deliberately did not remove text from direct quotes or paraphrases. The journalists and newspaper make intentional decisions about what text to include and exclude from quotations, which could still meaningfully represent their perspectives and values BIBREF69.\nAs in Section 3.1, we use Connotation Frames to quantify the amount of agency attributed to a target group.",

        "evidence": "Fake News Detection Exist studies for fake news detection can be roughly summarized into two categories. The first category is to extract or construct comprehensive and complex features with manual ways BIBREF5, BIBREF8, BIBREF17. The second category is to automatically capture deep features based on neural networks. There are two ways in this category. One is to capture linguistic features from text content, such as semantic BIBREF7, BIBREF18, writing styles BIBREF4, and textual entailments BIBREF19. The other is to focus on gaining effective features from the organic integration of text and user interactions BIBREF20, BIBREF21. User interactions include users' behaviours, profiles, and networks between users. In this work, following the second way, we automatically learn representations of text and stance information from response and forwarding (users' behaviour) based on multi-task learning for fake news detection.\nStance Detection The researches BIBREF22, BIBREF23 demonstrate that the stance detected from fake news can serve as an effective credibility indicator to improve the performance of fake news detection. The common way of stance detection in rumors is to catch deep semantics from text content based on neural networksBIBREF24. For instance, Kochkina et al.BIBREF25 project branch-nested LSTM model to encode text of each tweet considering the features and labels of the predicted tweets for stance detection, which reflects the best performance in RumourEval dataset. In this work, we utilize transformer encoder to acquire semantics from responses and forwarding of fake news for stance detection.\nMulti-task Learning A collection of improved models BIBREF26, BIBREF27, BIBREF28 are developed based on multi-task learning. Especially, shared-private model, as a popular multi-task learning model, divides the features of different tasks into private and shared spaces, where shared features, i.e., task-irrelevant features in shared space, as supplementary features are used for different tasks. Nevertheless, the shared space usually mixes some task-relevant features, which makes the learning of different tasks introduce noise. To address this issue, Liu et al. BIBREF29 explore an adversarial shared-private model to alleviate the shared and private latent feature spaces from interfering with each other. However, these models transmit all shared features in the shared layer to related tasks without distillation, which disturb specific tasks due to some useless and even harmful shared features.

        "evidence": "Single-document summarization is the task of generating a short summary for a given document. Ideally, the generated summaries should be fluent and coherent, and should faithfully maintain the most important information in the source document. purpleThis is a very challenging task, because it arguably requires an in-depth understanding of the source document, and current automatic solutions are still far from human performance BIBREF0 .\nSingle-document summarization can be either extractive or abstractive. Extractive methods typically pick sentences directly from the original document based on their importance, and form the summary as an aggregate of these sentences. Usually, summaries generated in this way have a better performance on fluency and grammar, but they may contain much redundancy and lack in coherence across sentences. In contrast, abstractive methods attempt to mimic what humans do by first extracting content from the source document and then produce new sentences that aggregate and organize the extracted information. Since the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar. Furthermore, while abstractive summaries are typically less redundant, they may end up including misleading or even utterly false statements, because the methods to extract and aggregate information form the source document are still rather noisy.\nIn this work, we focus on extracting informative sentences from a given document (without dealing with redundancy), especially when the document is relatively long (e.g., scientific articles).\nMost recent works on neural extractive summarization have been rather successful in generating summaries of short news documents (around 650 words/document) BIBREF1 by applying neural Seq2Seq models BIBREF2 . However when it comes to long documents, these models tend to struggle with longer sequences because at each decoding step, the decoder needs to learn to construct a context vector capturing relevant information from all the tokens in the source sequence BIBREF3 .\nLong documents typically cover multiple topics. In general, the longer a document is, the more topics are discussed. As a matter of fact, when humans write long documents they organize them in chapters, sections etc.. Scientific papers are an example of longer documents and they follow a standard discourse structure describing the problem, methodology, experiments/results, and finally conclusions BIBREF4 .\nTo the best of our knowledge only one previous work in extractive summarization has explicitly leveraged section information to guide the generation of summaries BIBREF5 . However, the only information about sections fed into their sentence classifier is a categorical feature with values like Highlight, Abstract, Introduction, etc., depending on which section the sentence appears in.\nIn contrast, in order to exploit section information, in this paper we propose to capture a distributed representation of both the global (the whole document) and the local context (e.g., the section/topic) when deciding if a sentence should be included in the summary\nOur main contributions are as follows: (i) In order to capture the local context, we are the first to apply LSTM-minus to text summarization. LSTM-minus is a method for learning embeddings of text spans, which has achieved good performance in dependency parsing BIBREF6 , in constituency parsing BIBREF7 , as well as in discourse parsing BIBREF8 . With respect to more traditional methods for capturing local context, which rely on hierarchical structures, LSTM-minus produces simpler models i.e. with less parameters, and therefore faster to train and less prone to overfitting. (ii) We test our method on the Pubmed and arXiv datasets and results appear to support our goal of effectively summarizing long documents. In particular, while overall we outperform the baseline and previous approaches only by a narrow margin on both datasets, the benefit of our method become much stronger as we apply it to longer documents. purpleFurthermore, in an ablation study to assess the relative contributions of the global and the local model we found that, rather surprisingly, the benefits of our model seem to come exclusively from modeling the local context, even for the longest documents.[6] (iii) In order to evaluate our approach, we have created oracle labels for both Pubmed and arXiv BIBREF9 , by applying a greedy oracle labeling algorithm. The two datasets annotated with extractive labels will be made public.\nSince the sentences are generated from scratch they tend to have a relatively worse performance on fluency and grammar.

        "evidence": "Recent studies have shown the vulnerability of ML models to adversarial attacks, small perturbations which lead to misclassification of inputs. Adversarial example generation in NLP BIBREF0 is more challenging than in common computer vision tasks BIBREF1, BIBREF2, BIBREF3 due to two main reasons: the discrete nature of input space and ensuring semantic coherence with the original sentence. A major bottleneck in applying gradient based BIBREF4 or generator model BIBREF5 based approaches to generate adversarial examples in NLP is the backward propagation of the perturbations from the continuous embedding space to the discrete token space.\nRecent works for attacking text models rely on introducing errors at the character level in words BIBREF6, BIBREF7 or adding and deleting words BIBREF8, BIBREF9, BIBREF10, etc. for creating adversarial examples. These techniques often result in adversarial examples which are unnatural looking and lack grammatical correctness, and thus can be easily identified by humans.\nTextFooler BIBREF11 is a black-box attack, that uses rule based synonym replacement from a fixed word embedding space to generate adversarial examples. These adversarial examples do not account for the overall semantics of the sentence, and consider only the token level similarity using word embeddings. This can lead to out-of-context and unnaturally complex replacements (see Table ), which can be easily identifiable by humans.\nThe recent advent of powerful language models BIBREF12, BIBREF13 in NLP has paved the way for using them in various downstream applications. In this paper, we present a simple yet novel technique: BAE (BERT-based Adversarial Examples), which uses a language model (LM) for token replacement to best fit the overall context. We perturb an input sentence by either replacing a token or inserting a new token in the sentence, by means of masking a part of the input and using a LM to fill in the mask (See Figure FIGREF1). BAE relies on the powerful BERT masked LM for ensuring grammatical correctness of the adversarial examples. Our attack beats the previous baselines by a large margin and confirms the inherent vulnerabilities of modern text classification models to adversarial attacks. Moreover, BAE produces more richer and natural looking adversarial examples as it uses the semantics learned by a LM.\nTo the best of our knowledge, we are the first to use a LM for adversarial example generation. We summarize our major contributions as follows:\n\nWe propose BAE, a novel strategy for generating natural looking adversarial examples using a masked language model.\nWe introduce 4 BAE attack modes, all of which are almost always stronger than previous baselines on 7 text classification datasets.\nWe show that, surprisingly, just a few replace/insert operations can reduce the accuracy of even a powerful BERT-based classifier by over $80\\%$ on some datasets.\n\nTo the best of our knowledge, we are the first to use a LM for generating adversarial examples.",

        "question": "What is the limitation of Microsoft’s MCTest?",
        "answer": "Their scale is not suitable for deep learning without pretraining on other data.",
        "evidence": "A crucial condition for applying deep-learning techniques is to have a huge amount of data available for training. For question answering this specifically means having a large number of document-question-answer triples available. While there is an unlimited amount of text available, coming up with relevant questions and the corresponding answers can be extremely labour-intensive if done by human annotators. There were efforts to provide such human-generated datasets, e.g. Microsoft's MCTest BIBREF17 , however their scale is not suitable for deep learning without pre-training on other data BIBREF18 (such as using pre-trained word embedding vectors).\nGoogle DeepMind managed to avoid this scale issue with their way of generating document-question-answer triples automatically, closely followed by Facebook with a similar method. Let us now briefly introduce the two resulting datasets whose properties are summarized in Table TABREF8 .\nThese two datasets BIBREF1 exploit a useful feature of online news articles – many articles include a short summarizing sentence near the top of the page. Since all information in the summary sentence is also presented in the article body, we get a nice cloze-style question about the article contents by removing a word from the short summary.\nThe dataset's authors also replaced all named entities in the dataset by anonymous tokens which are further shuffled for each new batch. This forces the model to rely solely on information from the context document, not being able to transfer any meaning of the named entities between documents.\nThis restricts the task to one specific aspect of context-dependent question answering which may be useful however it moves the task further from the real application scenario, where we would like the model to use all information available to answer questions. Furthermore Chen et al. BIBREF5 have suggested that this can make about 17% of the questions unanswerable even by humans. They also claim that more than a half of the question sentences are mere paraphrases or exact matches of a single sentence from the context document. This raises a question to what extent the dataset can test deeper understanding of the articles.\nThe Children's Book Test BIBREF2 uses a different source - books freely available thanks to Project Gutenberg. Since no summary is available, each example consists of a context document formed from 20 consecutive sentences from the story together with a question formed from the subsequent sentence.\nThe dataset comes in four flavours depending on what type of word is omitted from the question sentence. Based on human evaluation done in BIBREF2 it seems that NE and CN are more context dependent than the other two types – prepositions and verbs. Therefore we (and all of the recent publications) focus only on these two word types.\nSeveral new datasets related to the (now almost standard) ones above emerged recently. We will now briefly present them and explain how the dataset we are introducing in this article differs from them.\nThe LAMBADA dataset BIBREF19 is designed to measure progress in understanding common-sense questions about short stories that can be easily answered by humans but cannot be answered by current standard machine-learning models (e.g. plain LSTM language models). This dataset is useful for measuring the gap between humans and machine learning algorithms. However, by contrast to our BookTest dataset, it will not allow us to track progress towards the performance of the baseline systems or on examples where machine learning may show super-human performance. Also LAMBADA is just a diagnostic dataset and does not provide ready-to-use question-answering training data, just a plain-text corpus which may moreover include copyrighted books making its use potentially problematic for some purposes. We are providing ready training data consisting of copyright-free books only.\nThe SQuAD dataset BIBREF20 based on Wikipedia and the Who-did-What dataset BIBREF21 based on Gigaword news articles are factoid question-answering datasets where a multi-word answer should be extracted from a context document. This is in contrast to the previous datasets, including CNN/DM, CBT, LAMBADA and our new dataset, which require only single-word answers. Both these datasets however provide less than 130,000 training questions, two orders of magnitude less than our dataset does.\nThe Story Cloze Test BIBREF22 provides a crowd-sourced corpus of 49,255 commonsense stories for training and 3,744 testing stories with right and wrong endings. Hence the dataset is again rather small. Similarly to LAMBADA, the Story Cloze Test was designed to be easily answerable by humans.\nIn the WikiReading BIBREF23 dataset the context document is formed from a Wikipedia article and the question-answer pair is taken from the corresponding WikiData page. For each entity (e.g. Hillary Clinton), WikiData contain a number of property-value pairs (e.g. place of birth: Chicago) which form the datasets's question-answer pairs. The dataset is certainly relevant to the community, however the questions are of very limited variety with only 20 properties (and hence unique questions) covering INLINEFORM0 of the dataset. Furthermore many of the frequent properties are mentioned at a set spot within the article (e.g. the date of birth is almost always in brackets behind the name of a person) which may make the task easier for machines. We are trying to provide a more varied dataset.\nAlthough there are several datasets related to task we are aiming to solve, they differ sufficiently for our dataset to bring new value to the community. Its biggest advantage is its size which can furthermore be easily upscaled without expensive human annotation. Finally while we are emphasizing the differences, models could certainly benefit from as diverse a collection of datasets as possible.\nThere were efforts to provide such human-generated datasets, e.g. Microsoft’s MCTest (Richardson et al., 2013), however their scale is not suitable for deep learning without pretraining on other data (Trischler et al., 2016a) (such as using pre-trained word embedding vectors).",

        "answer": "Cheese production has a long history in France. It is believed that cheese was first introduced into France during Roman times. After the fall of the Roman empire, monasteries continued the production of cheese. Experimentation within the monasteries, regional isolation and differences in climate and vegetation across France lead to the creation of regional varieties of cheese (some of which still exist today). From about the 13th century onwards, cheese production started to develop on French farms. Over time, the recipes for making cheese were handed down from generation to generation (and tweaked and improved by each generation), further increasing the number of varieties. \n\nAs a result, today it is commonly considered that there are between 350 and 400 different types of French cheese – although there are actually almost 1,000 varieties! These cheeses are made from cows, sheep, goats or buffalo milk.\n\nCharles de Gaulle, a famous French president, once asked - \"How can you govern a country which has 246 varieties of cheese?\" It would be interesting to hear what his thoughts would be today now that there are almost 1000 different varieties.",

According to historian P. Thankappan Nair, dosa originated in the town of Udupi in present-day Karnataka. However, according to food historian K. T. Achaya, references in the Sangam literature suggest that dosa was already in use in the ancient Tamil country around the 1st century CE. Achaya states that the earliest written mention of dosa appears in literature of present-day Tamil Nadu, in the 8th century, while the earliest mention of dosa in the Kannada literature appears a century later.\n\nIn popular tradition, the origin of the dosa is linked to Udupi, probably because of the dish's association with Udupi restaurants. The Tamil dosai is softer and thicker. The thinner and crispier version of dosa was first made in present-day Karnataka. A recipe for dosa can be found in Manasollasa, a 12th-century Sanskrit encyclopedia compiled by Someshvara III, who ruled from present-day Karnataka.\n\nAfter the Independence of India, South Indian cuisine became gradually popular in the North. In Delhi, the Madras Hotel in Connaught Place became one of the first restaurants to serve South Indian cuisine. It arrived in Mumbai with the Udupi restaurants in the 1930s.",

        "evidence": "Traditional text-to-speech (TTS) systems are composed of complex pipelines BIBREF0 , these often include accoustic frontends, duration model, acoustic prediction model and vocoder models. The complexity of the TTS problem coupled with the requirement for deep domain expertise means these systems are often brittle in design and results in un-natural synthesized speech.\nNeural text-to-speech systems have garnered large research interest in the past 2 years. The first to fully explore this avenue of research was Google's tacotron BIBREF1 system. Their architecture based off the original Seq2Seq framework. In addition to encoder/decoder RNNs from the original Seq2Seq , they also included a bottleneck prenet module termed CBHG, which is composed of sets of 1-D convolution networks followed by highway residual layers. The attention mechanism follows the original Seq2Seq BIBREF7 mechanism (often termed Bahdanau attention). This is the first work to propose training a Seq2Seq model to convert text to mel spectrogram, which can then be converted to audio wav via iterative algorithms such as Griffin Lim BIBREF8 .\nThe architecture of our model utilizes RNN-based Seq2Seq model for generating mel spectrogram from text. The architecture is similar to that of Tacotron 2 BIBREF4 . The generated mel spetrogram can either be inverted via iterative algorithms such as Griffin Lim, or through more complicated neural vocoder networks such as a mel spectrogram conditioned Wavenet BIBREF11 .\nIn the original Tacotron 2, the attention mechanism used was location sensitive attention BIBREF12 combined the original additive Seq2Seq BIBREF7 Bahdanau attention.\nWe propose to replace this attention with the simpler query-key attention from transformer model. As mentioned earlier, since for TTS the attention mechanism is an easier problem than say machine translation, we employ query-key attention as it's simple to implement and requires less parameters than the original Bahdanau attention.\nFollowing the logic above, we utilize a similar method from BIBREF6 that adds an additional guided attention loss to the overall loss objective, which acts to help the attention mechanism become monotoic as early as possible.\nAs seen from FIGREF24 , an attention loss mask, INLINEFORM0 , is created applies a loss to force the attention alignment, INLINEFORM1 , to be nearly diagonal.

Meanwhile, KBMRC facilitates the accessing and leveraging of knowledge from external KBs because the document KB is consistent with the representation of facts in external KBs.\nKBMRC also relates to knowledge-base question answering (KBQA) BIBREF23 , which aims to answer questions based on an external large-scale KB such as Freebase or ProBase. KBMRC differs from KBQA in that the original KB comes from the content of a document. External KB is used in this work to enhance the document KB. Moreover, existing benchmark datasets for KBQA such as WebQuestions BIBREF24 are typically limited to simple questions. The KBMRC task requires reasoning over two facts from the document KB.\nOur approach draws inspiration from two main classes in existing approaches of KBQA, namely ranking based and parsing based. Ranking based approaches BIBREF17 , BIBREF25 are bottom-up, which typically first find a set of candidate answers and then rank between the candidates with features at different levels to get the answer. Parsing-based approaches BIBREF16 are top-down, which first interpret logical form from a natural language utterance, and then do execution to yield the answer. Ranking-based approaches achieve better performances than parsing-based approaches on WebQuestions, a benchmark dataset for KBQA. We follow ranking-based approaches, and develop both a matching-based model with features at different levels and a question generation model. More references can be found at https://aclweb.org/aclwiki/Question_Answering_(State_of_the_art).\nOur work also relates to BIBREF21 khot2017answering, which uses open IE outputs from external text corpora to improve multi-choice question answering. However, our work differs from them in that their task does not contain document information. Furthermore, we develop a question generation approach while they regard the QA task as subgraph search based on an integer linear programming (ILP) approach. Our work also relates to BIBREF26 khashabi2018question, which focuses on multi-choice question answering based on the semantics of a document. They use semantic role labeling and shallow parsing of a document to construct a semantic graph, based on which an ILP based approach is developed to find the supporting subgraph. The difference of our approach is that predicates from our document KB form are not limited to a predefined set, so that they do not take into consideration the knowledge from external KBs, and also the difference in terms of methodology. BIBREF19 miller2016key answer questions based on KBs in the movie domain or information extraction results from Wikipedia documents. Unlike this method, our approach focuses on entities from an external KB, our doc KB is obtained via open IE, and we combine the document KB with an open KB for question answering.\nThe task of KBMRC differs from machine reading comprehension (MRC) in both input and output aspects.

We tried training our estimator for different magnitudes of R and different amounts of additive observation noise. Without noise (similar to the examples shown in the paper), the estimation accuracy decreases as R increases. In the presence of noise, the estimator is indeed more accurate for larger magnitudes of R. We have added an appendix describing these findings in the revised paper. The effect of R on the generalization performance of the estimator is a very interesting question that we leave for future work.",

The results for the unforced case are shown in Figures 10, 11, and 12 for observation noise of standard deviation σ = 0, 0.1, and 0.3, respectively.

In absence of noise, the highest estimation accuracy is obtained for R = 0, and decreases as R increases. However, in the presence of noise, Figures 11, 12, and 14, 15, the estimation accuracy is generally highest for R = 10.

        "answer": "Federalism is a system of government where the power is distributed across different levels. In the United States, we have a system with two levels, a federal or national government, and underneath that state governments.  Dual federalism is a period between 1819 and 1936 where there was a clear separation of powers between the federal government and the state governments.  During this time the “national government left the states largely to their own devices in major policy areas” which included “education, transportation, and civil rights, among others”.  \nDuring the dual federalism period, two important cases set the stage for the next time period called “cooperative federalism” (1936-present).  The first case was McCulloch v. Maryland which cited the Constitution's  supremacy clause and implied powers of the federal government in a verdict that prohibited the state of Maryland from taxing a federal bank.  The second case was Gibbons v. Ogden which cited the power of the federal government to regulate interstate commerce giving Gibbons a monopoly to ferry people from New Jersey to New York.  These two cases were used by the Federal government during the New Deal as precedent to enable cooperative federalism which is “an intermingling of power, policy, and resources among the national and state governments”.

        "answer": "Gradient-based attacks, optimisationbased attacks and model-based attacks.",
        "evidence": "Most existing adversarial attack methods for text inputs are derived from those for image inputs. These methods can be categorised into three types including gradient-based attacks, optimisation-based attacks and model-based attacks.\nGradient-based attacks are mainly white-box attacks that rely on calculating the gradients of the target classifier with respect to the input representation. This class of attacking methods BIBREF6, BIBREF7, BIBREF6 are mainly derived from the fast gradient sign method (FGSM) BIBREF1, and it has been shown to be effective in attacking CV classifiers. However, these gradient-based methods could not be applied to text directly because perturbed word embeddings do not necessarily map to valid words. Other methods such as DeepFool BIBREF8 that rely on perturbing the word embedding space face similar roadblocks. BIBREF5 propose to use nearest neighbour search to find the closest word to the perturbed embedding.\nBoth optimisation-based and model-based attacks treat adversarial attack as an optimisation problem where the constraints are to maximise the loss of target classifiers and to minimise the difference between original and adversarial examples. Between these two, the former uses optimisation algorithms directly; while the latter trains a seperate model to generate adversarial examples and therefore involves a training process. Some of the most effective attacks for images are achieved by optimisation-based methods, such as the L-BFGS attack BIBREF1 and the C&W attack BIBREF9 in white-box attacks and the ZOO method BIBREF10 in black-box attacks. For texts, the white-box attack HotFlip BIBREF3 and black-box attack DeepWordBug BIBREF11 and TextBugger BIBREF12 are proposed in this category.\nIn a similar vein, a few model-based attacks have been proposed for images, e.g. BIBREF13 design a generative adversarial network (GAN) to generate the image perturbation from a noise map. The attacking method and target classifier typically form a single large network and the attacking method is trained using the loss from the target classifier. For this reason, it is not very straightforward to use these model-based techniques for text because there is a discontinuity in the network (since words in the adversarial examples are discrete) and so it is not fully differentiable.\nMost adversarial attack methods for text inputs are derived from methods originally designed for image inputs.

        "evidence": "“Ché saetta previsa vien più lenta.”\n\n– Dante Alighieri, Divina Commedia, Paradiso\nAntisocial behavior is a persistent problem plaguing online conversation platforms; it is both widespread BIBREF0 and potentially damaging to mental and emotional health BIBREF1, BIBREF2. The strain this phenomenon puts on community maintainers has sparked recent interest in computational approaches for assisting human moderators.\nPrior work in this direction has largely focused on post-hoc identification of various kinds of antisocial behavior, including hate speech BIBREF3, BIBREF4, harassment BIBREF5, personal attacks BIBREF6, and general toxicity BIBREF7. The fact that these approaches only identify antisocial content after the fact limits their practicality as tools for assisting pre-emptive moderation in conversational domains.\nAddressing this limitation requires forecasting the future derailment of a conversation based on early warning signs, giving the moderators time to potentially intervene before any harm is done (BIBREF8 BIBREF8, BIBREF9 BIBREF9, see BIBREF10 BIBREF10 for a discussion). Such a goal recognizes derailment as emerging from the development of the conversation, and belongs to the broader area of conversational forecasting, which includes future-prediction tasks such as predicting the eventual length of a conversation BIBREF11, whether a persuasion attempt will eventually succeed BIBREF12, BIBREF13, BIBREF14, whether team discussions will eventually lead to an increase in performance BIBREF15, or whether ongoing counseling conversations will eventually be perceived as helpful BIBREF16.\nApproaching such conversational forecasting problems, however, requires overcoming several inherent modeling challenges. First, conversations are dynamic and their outcome might depend on how subsequent comments interact with each other. Consider the example in Figure FIGREF2: while no individual comment is outright offensive, a human reader can sense a tension emerging from their succession (e.g., dismissive answers to repeated questioning). Thus a forecasting model needs to capture not only the content of each individual comment, but also the relations between comments. Previous work has largely relied on hand-crafted features to capture such relations—e.g., similarity between comments BIBREF16, BIBREF12 or conversation structure BIBREF17, BIBREF18—, though neural attention architectures have also recently shown promise BIBREF19.\nThe second modeling challenge stems from the fact that conversations have an unknown horizon: they can be of varying lengths, and the to-be-forecasted event can occur at any time. So when is it a good time to make a forecast? Prior work has largely proposed two solutions, both resulting in important practical limitations. One solution is to assume (unrealistic) prior knowledge of when the to-be-forecasted event takes place and extract features up to that point BIBREF20, BIBREF8. Another compromising solution is to extract features from a fixed-length window, often at the start of the conversation BIBREF21, BIBREF15, BIBREF16, BIBREF9. Choosing a catch-all window-size is however impractical: short windows will miss information in comments they do not encompass (e.g., a window of only two comments would miss the chain of repeated questioning in comments 3 through 6 of Figure FIGREF2), while longer windows risk missing the to-be-forecasted event altogether if it occurs before the end of the window, which would prevent early detection.\nIn this work we introduce a model for forecasting conversational events that overcomes both these inherent challenges by processing comments, and their relations, as they happen (i.e., in an online fashion). Our main insight is that models with these properties already exist, albeit geared toward generation rather than prediction: recent work in context-aware dialog generation (or “chatbots”) has proposed sequential neural models that make effective use of the intra-conversational dynamics BIBREF22, BIBREF23, BIBREF24, while concomitantly being able to process the conversation as it develops (see BIBREF25 for a survey).\nIn order for these systems to perform well in the generative domain they need to be trained on massive amounts of (unlabeled) conversational data. The main difficulty in directly adapting these models to the supervised domain of conversational forecasting is the relative scarcity of labeled data: for most forecasting tasks, at most a few thousands labeled examples are available, insufficient for the notoriously data-hungry sequential neural models.\nTo overcome this difficulty, we propose to decouple the objective of learning a neural representation of conversational dynamics from the objective of predicting future events. The former can be pre-trained on large amounts of unsupervised data, similarly to how chatbots are trained. The latter can piggy-back on the resulting representation after fine-tuning it for classification using relatively small labeled data. While similar pre-train-then-fine-tune approaches have recently achieved state-of-the-art performance in a number of NLP tasks—including natural language inference, question answering, and commonsense reasoning (discussed in Section SECREF2)—to the best of our knowledge this is the first attempt at applying this paradigm to conversational forecasting.\nTo test the effectiveness of this new architecture in forecasting derailment of online conversations, we develop and distribute two new datasets. The first triples in size the highly curated `Conversations Gone Awry' dataset BIBREF9, where civil-starting Wikipedia Talk Page conversations are crowd-labeled according to whether they eventually lead to personal attacks; the second relies on in-the-wild moderation of the popular subreddit ChangeMyView, where the aim is to forecast whether a discussion will later be subject to moderator action due to “rude or hostile” behavior. In both datasets, our model outperforms existing fixed-window approaches, as well as simpler sequential baselines that cannot account for inter-comment relations. Furthermore, by virtue of its online processing of the conversation, our system can provide substantial prior notice of upcoming derailment, triggering on average 3 comments (or 3 hours) before an overtly toxic comment is posted.\nTo summarize, in this work we:\nintroduce the first model for forecasting conversational events that can capture the dynamics of a conversation as it develops;\nbuild two diverse datasets (one entirely new, one extending prior work) for the task of forecasting derailment of online conversations;\ncompare the performance of our model against the current state-of-the-art, and evaluate its ability to provide early warning signs.\nOur work is motivated by the goal of assisting human moderators of online communities by preemptively signaling at-risk conversations that might deserve their attention. However, we caution that any automated systems might encode or even amplify the biases existing in the training data BIBREF26, BIBREF27, BIBREF28, so a public-facing implementation would need to be exhaustively scrutinized for such biases BIBREF29.\n\nIn this work we introduce a model for forecasting conversational events that overcomes both these inherent challenges by processing comments, and their relations, as they happen (i.e., in an online fashion).",

There are many types of intellectual property, and some countries recognize more than others. The best-known types are patents, copyrights, trademarks, and trade secrets. The modern concept of intellectual property developed in England in the 17th and 18th centuries. The term \"intellectual property\" began to be used in the 19th century, though it was not until the late 20th century that intellectual property became commonplace in most of the world's legal systems.\n\nThe main purpose of intellectual property law is to encourage the creation of a wide variety of intellectual goods. To achieve this, the law gives people and businesses property rights to the information and intellectual goods they create, usually for a limited period of time. This gives economic incentive for their creation, because it allows people to benefit from the information and intellectual goods they create, and allows them to protect their ideas and prevent copying. These economic incentives are expected to stimulate innovation and contribute to the technological progress of countries, which depends on the extent of protection granted to innovators.\n\nThe intangible nature of intellectual property presents difficulties when compared with traditional property like land or goods. Unlike traditional property, intellectual property is \"indivisible\", since an unlimited number of people can \"consume\" an intellectual good without its being depleted.Additionally, investments in intellectual goods suffer from appropriation problems: Landowners can surround their land with a robust fence and hire armed guards to protect it, but producers of information or literature can usually do little to stop their first buyer from replicating it and selling it at a lower price. Balancing rights so that they are strong enough to encourage the creation of intellectual goods but not so strong that they prevent the goods' wide use is the primary focus of modern intellectual property law.",

In the context of question answering, question classification allows automated systems to intelligently target their inference systems to domain-specific solvers capable of addressing specific kinds of questions and problem solving methods with high confidence and answer accuracy BIBREF0 , BIBREF1 .\nTo date, question classification has primarily been studied in the context of open-domain TREC questions BIBREF2 , with smaller recent datasets available in the biomedical BIBREF3 , BIBREF4 and education BIBREF5 domains. The open-domain TREC question corpus is a set of 5,952 short factoid questions paired with a taxonomy developed by Li and Roth BIBREF6 that includes 6 coarse answer types (such as entities, locations, and numbers), and 50 fine-grained types (e.g. specific kinds of entities, such as animals or vehicles). While a wide variety of syntactic, semantic, and other features and classification methods have been applied to this task, culminating in near-perfect classification performance BIBREF7 , recent work has demonstrated that QC methods developed on TREC questions generally fail to transfer to datasets with more complex questions such as those in the biomedical domain BIBREF3 , likely due in part to the simplicity and syntactic regularity of the questions, and the ability for simpler term-frequency models to achieve near-ceiling performance BIBREF8 . In this work we explore question classification in the context of multiple choice science exams. Standardized science exams have been proposed as a challenge task for question answering BIBREF9 , as most questions contain a variety of challenging inference problems BIBREF10 , BIBREF11 , require detailed scientific and common-sense knowledge to answer and explain the reasoning behind those answers BIBREF12 , and questions are often embedded in complex examples or other distractors. Question classification taxonomies and annotation are difficult and expensive to generate, and because of the unavailability of this data, to date most models for science questions use one or a small number of generic solvers that perform little or no question decomposition BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 , BIBREF17 . Our long-term interest is in developing methods that intelligently target their inferences to generate both correct answers and compelling human-readable explanations for the reasoning behind those answers. The lack of targeted solving – using the same methods for inferring answers to spatial questions about planetary motion, chemical questions about photosynthesis, and electrical questions about circuit continuity – is a substantial barrier to increasing performance (see Figure FIGREF1 ).\nTo address this need for developing methods of targetted inference, this work makes the following contributions:\nthis work makes the following contributions:  1. We provide a large challenge dataset of question classification labels for 7,787 standardized science exam questions labeled using a hierarchical taxonomy of 406 detailed problem types across 6 levels of granularity.

SQuAD is much larger in size although questions in this corpus are often paraphrased multiple times. On the contrary, SQuAD's average candidates per question ( INLINEFORM0 ) is the smallest because SQuAD extracts answer candidates from paragraphs whereas the others extract them from sections or infoboxes that consist of bigger contexts. Although InfoboxQA is larger than WikiQA or SelQA, the number of token types ( INLINEFORM1 ) in InfoboxQA is smaller than those two, due to the repetitive nature of infoboxes.\nAll corpora show similar average answer candidate lengths ( INLINEFORM0 ), except for InfoboxQA where each line in the infobox is considered a candidate. SelQA and SQuAD show similar average question lengths ( INLINEFORM1 ) because of the similarity between their annotation schemes. It is not surprising that WikiQA's average question length is the smallest, considering their questions are taken from search queries. InfoboxQA's average question length is relatively small, due to the restricted information that can be asked from the infoboxes. InfoboxQA and WikiQA show the least question-answer word overlaps over questions and answers ( INLINEFORM2 and INLINEFORM3 in Table TABREF2 ), respectively.

        "question": "Is the dataset introduced by the authors the first dataset for RA-MDS?",
        "answer": "Yes, it is.",
        "evidence": "The goal of multi-document summarization (MDS) is to automatically generate a brief, well-organized summary for a topic which describes an event with a set of documents from different sources. BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . In the typical setting of MDS, the input is a set of news documents about the same topic. The output summary is a piece of short text document containing several sentences, generated only based on the input original documents.\nWith the development of social media and mobile equipments, more and more user generated content is available. Figure FIGREF2 is a snapshot of reader comments under the news report “The most important announcements from Google's big developers' conference”. The content of the original news report talks about some new products based on AI techniques. The news report generally conveys an enthusiastic tone. However, while some readers share similar enthusiasms, some others express their worries about new products and technologies and these comments can also reflect their interests which may not be very salient in the original news reports. Unfortunately, existing MDS approaches cannot handle this issue. We investigate this problem known as reader-aware multi-document summarization (RA-MDS). Under the RA-MDS setting, one should jointly consider news documents and reader comments when generating the summaries.\nOne challenge of the RA-MDS problem is how to conduct salience estimation by jointly considering the focus of news reports and the reader interests revealed by comments. Meanwhile, the model should be insensitive to the availability of diverse aspects of reader comments. Another challenge is that reader comments are very noisy, not fully grammatical and often expressed in informal expressions. Some previous works explore the effect of comments or social contexts in single document summarization such as blog summarization BIBREF7 , BIBREF8 . However, the problem setting of RA-MDS is more challenging because the considered comments are about an event which is described by multiple documents spanning a time period. Another challenge is that reader comments are very diverse and noisy. Recently, BIBREF9 employed a sparse coding based framework for RA-MDS jointly considering news documents and reader comments via an unsupervised data reconstruction strategy. However, they only used the bag-of-words method to represent texts, which cannot capture the complex relationship between documents and comments.\nRecently, BIBREF6 proposed a sentence salience estimation framework known as VAESum based on a neural generative model called Variational Auto-Encoders (VAEs) BIBREF10 , BIBREF11 . During our investigation, we find that the Gaussian based VAEs have a strong ability to capture the salience information and filter the noise from texts. Intuitively, if we feed both the news sentences and the comment sentences into the VAEs, commonly existed latent aspect information from both of them will be enhanced and become salient. Inspired by this consideration, to address the sentence salience estimation problem for RA-MDS by jointly considering news documents and reader comments, we extend the VAESum framework by training the news sentence latent model and the comment sentence latent model simultaneously by sharing the neural parameters. After estimating the sentence salience, we employ a phrase based compressive unified optimization framework to generate a final summary.\nThere is a lack of high-quality dataset suitable for RA-MDS. Existing datasets from DUC and TAC are not appropriate. Therefore, we introduce a new dataset for RA-MDS. We employed some experts to conduct the tasks of data collection, aspect annotation, and summary writing as well as scrutinizing. To our best knowledge, this is the first dataset for RA-MDS.\nOur contributions are as follows: (1) We investigate the RA-MDS problem and introduce a new dataset for the problem of RA-MDS. To our best knowledge, it is the first dataset for RA-MDS. (2) To tackle the RA-MDS, we extend a VAEs-based MDS framework by jointly considering news documents and reader comments. (3) Experimental results show that reader comments can improve the summarization performance, which also demonstrates the usefulness of the dataset.\nTo our best knowledge, this is the first dataset for RA-MDS.",

        "question": "What data sets did the author experiment with?",
        "answer": "MR, SST-2, SST-5, SUBJ and TREC.",
        "evidence": "One of the most basic approaches to evaluate a sentence encoder is to measure the classification performance with the sentence representations made by the encoder. Thus, we conduct experiments on the following five datasets. (Summary statistics for the datasets are reported in the supplemental materials.)\nMR: A group of movie reviews with binary (positive / negative) classes. BIBREF22 \nSST-2: Stanford Sentiment Treebank BIBREF6 . Similar to MR, but each review is provided in the form of a binary parse tree whose nodes are annotated with numeric sentiment values. For SST-2, we only consider binary (positive / negative) classes.\nSST-5: Identical to SST-2, but the reviews are grouped into fine-grained (very negative, negative, neutral, positive, very positive) classes.\nSUBJ: Sentences grouped as being either subjective or objective (binary classes). BIBREF23 \nTREC: A dataset which groups questions into six different question types (classes). BIBREF24 \nAs a preprocessing step, we construct parse trees for the sentences in the datasets using the Stanford PCFG parser BIBREF25 . Because syntactic tags are by-products of constituency parsing, we do not need further preprocessing.\nTo classify the sentence given our sentence representation ( $\\check{\\mathbf {h}}_\\text{root}$ ), we use one fully-connected layer with a ReLU activation, followed by a softmax classifier. The final predicted probability distribution of the class $y$ given the sentence $w_{1:n}$ is defined as follows, \n$$\\mathbf {s} = \\text{ReLU}(\\mathbf {W}_\\text{s} \\check{\\mathbf {h}}_\\text{root}+ \\mathbf {b}_\\text{s})$$   (Eq. 37) \n$$p(y|w_{1:n}) = \\text{softmax}(\\mathbf {W}_\\text{c}\\mathbf {s} + \\mathbf {b}_\\text{c})$$   (Eq. 38) \nwhere $\\textbf {s} \\in \\mathbb {R}^{d_\\text{s}}$ is the computed task-specific sentence representation for the classifier, and $\\textbf {W}_\\text{s} \\in \\mathbb {R}^{d_\\text{s} \\times d_h}$ , $\\textbf {W}_\\text{c} \\in \\mathbb {R}^{d_\\text{c} \\times d_s}$ , $\\textbf {b}_\\text{s} \\in \\mathbb {R}^{d_s}$ , $\\textbf {b}_\\text{c} \\in \\mathbb {R}^{d_c}$ are trainable parameters. As an objective function, we use the cross entropy of the predicted and true class distributions.\nThe results of the experiments on the five datasets are shown in table 1 . In this table, we report the test accuracy of our model and various other models on each dataset in terms of percentage. To consider the effects of random initialization, we report the best numbers obtained from each several runs with hyper-parameters fixed.\nCompared with the previous syntactic tree-based models as well as other neural models, our SATA Tree-LSTM shows superior or competitive performance on all tasks. Specifically, our model achieves new state-of-the-art results within the tree-structured model class on 4 out of 5 sentence classification tasks—SST-2, SST-5, MR, and TREC. The model shows its strength, in particular, when the datasets provide phrase-level supervision to facilitate tree structure learning (i.e. SST-2, SST-5). Moreover, the numbers we report for SST-5 and TREC are competitive to the existing state-of-the-art results including ones from structurally pre-trained models such as ELMo BIBREF26 , proving our model's superiority. Note that the SATA Tree-LSTM also outperforms the recent latent tree-based model, indicating that modeling a neural model with explicit linguistic knowledge can be an attractive option.\nOn the other hand, a remaining concern is that our SATA Tree-LSTM is not robust to random seeds when the size of a dataset is relatively small, as tag embeddings are randomly initialized rather than relying on pre-trained ones in contrast with the case of words. From this observation, we could find out there needs a direction of research towards pre-trained tag embeddings.\nTo estimate the performance of our model beyond the tasks requiring only one sentence at a time, we conduct an experiment on the Stanford Natural Language Inference BIBREF34 dataset, each example of which consists of two sentences, the premise and the hypothesis. Our objective given the data is to predict the correct relationship between the two sentences among three options— contradiction, neutral, or entailment.\nWe use the siamese architecture to encode both the premise ( $p_{1:m}$ ) and hypothesis ( $h_{1:n}$ ) following the standard of sentence-encoding models in the literature. (Specifically, $p_{1:m}$ is encoded as $\\check{\\mathbf {h}}_\\text{root}^p \\in \\mathbb {R}^{d_h}$ and $h_{1:n}$ is encoded as $\\check{\\mathbf {h}}_\\text{root}^h \\in \\mathbb {R}^{d_h}$ with the same encoder.) Then, we leverage some heuristics BIBREF35 , followed by one fully-connected layer with a ReLU activation and a softmax classifier. Specifically, \n$$\\mathbf {z} = \\left[ \\check{\\mathbf {h}}_\\text{root}^p; \\check{\\mathbf {h}}_\\text{root}^h; | \\check{\\mathbf {h}}_\\text{root}^p - \\check{\\mathbf {h}}_\\text{root}^h |; \\check{\\mathbf {h}}_\\text{root}^p \\odot \\check{\\mathbf {h}}_\\text{root}^h \\right]$$   (Eq. 41) \n$$\\mathbf {s} = \\text{ReLU}(\\mathbf {W}_\\text{s} \\mathbf {z} + \\mathbf {b}_\\text{s})$$   (Eq. 42) \nwhere $\\textbf {z} \\in \\mathbb {R}^{4d_h}$ , $\\textbf {s} \\in \\mathbb {R}^{d_s}$ are intermediate features for the classifier and $\\textbf {W}_\\text{s} \\in \\mathbb {R}^{d_\\text{s} \\times 4d_h}$ , $\\textbf {W}_\\text{c} \\in \\mathbb {R}^{d_\\text{c} \\times d_s}$ , $\\textbf {b}_\\text{s} \\in \\mathbb {R}^{d_s}$ , $\\textbf {b}_\\text{c} \\in \\mathbb {R}^{d_c}$ are again trainable parameters.\nOur experimental results on the SNLI dataset are shown in table 2 . In this table, we report the test accuracy and number of trainable parameters for each model. Our SATA-LSTM again demonstrates its decent performance compared against the neural models built on both syntactic trees and latent trees, as well as the non-tree models. (Latent Syntax Tree-LSTM: BIBREF10 ( BIBREF10 ), Tree-based CNN: BIBREF35 ( BIBREF35 ), Gumbel Tree-LSTM: BIBREF11 ( BIBREF11 ), NSE: BIBREF36 ( BIBREF36 ), Reinforced Self-Attention Network: BIBREF4 ( BIBREF4 ), Residual stacked encoders: BIBREF37 ( BIBREF37 ), BiLSTM with generalized pooling: BIBREF38 ( BIBREF38 ).) Note that the number of learned parameters in our model is also comparable to other sophisticated models, showing the efficiency of our model.\nEven though our model has proven its mettle, the effect of tag information seems relatively weak in the case of SNLI, which contains a large amount of data compared to the others. One possible explanation is that neural models may learn some syntactic rules from large amounts of text when the text size is large enough, reducing the necessity of external linguistic knowledge. We leave the exploration of the effectiveness of tags relative to data size for future work.\nHere we go over the settings common across our models during experimentation. For more task-specific details, refer to the supplemental materials.\nFor our input embeddings, we used 300 dimensional 840B GloVe BIBREF39 as pre-trained word embeddings, and tag representations were randomly sampled from the uniform distribution [-0.005, 0.005]. Tag vectors are revised during training while the fine-tuning of the word embedding depends on the task. Our models were trained using the Adam BIBREF40 or Adadelta BIBREF41 optimizer, depending on task. For regularization, weight decay is added to the loss function except for SNLI following BIBREF42 ( BIBREF42 ) and Dropout BIBREF43 is also applied for the word embeddings and task-specific classifiers. Moreover, batch normalization BIBREF44 is adopted for the classifiers. As a default, all the weights in the model are initialized following BIBREF45 ( BIBREF45 ) and the biases are set to 0. The total norm of the gradients of the parameters is clipped not to be over 5 during training.\nOur best models for each dataset were chosen by validation accuracy in cases where a validation set was provided as a part of the dataset. Otherwise, we perform a grid search on probable hyper-parameter settings, or run 10-fold cross-validation in cases where even a test set does not exist.\n• MR: A group of movie reviews with binary (positive / negative) classes. • SST-2: Stanford Sentiment Treebank.

These models are typically trained only on sequences of words, ignoring the physical context in which the symbolic representations are grounded, or ignoring the social context that could inform the semantics of an utterance.\nFor incorporating additional modalities, the NLP community has typically used datasets such as MS COCO BIBREF1 and Flickr BIBREF2 for image-based tasks, while several datasets BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 , BIBREF7 have been curated for video-based tasks. Despite the lack of big datasets, researchers have started investigating language grounding in images BIBREF8 , BIBREF9 , BIBREF10 and to lesser extent in videos BIBREF11 , BIBREF1 . However, language grounding has focused more on obtaining better word and sentence representations or other downstream tasks, and to lesser extent on language modeling.\nIn this paper, we examine the problem of incorporating temporal visual context into a recurrent neural language model (RNNLM). Multimodal Neural Language Models were introduced in BIBREF12 , where log-linear LMs BIBREF13 were conditioned to handle both image and text modalities. Notably, this work did not use the recurrent neural model paradigm which has now become the de facto way of implementing neural LMs.\nThe closest work to ours is that of BIBREF0 , who report perplexity gains of around 5–6% on three languages on the MS COCO dataset (with an English vocabulary of only 16K words).\nOur work is distinguishable from previous work with respect to three dimensions:\nIn this paper, we examine the problem of incorporating temporal visual context into a recurrent neural language model (RNNLM).",

Hard magic systems follow specific rules, the magic is controlled and explained to the reader in the narrative detailing the mechanics behind the way the magic 'works' and can be used for building settings that revolve around the magic system.

Therefore, we make comparisons with other models regarding only their sentence boundary F1 scores. The equation for the sentence boundary F1 score metric is shown in f1sb. In calculating the F1 score, the positive class is defined as the sentence boundary, and the negative class is defined as the non-sentence boundary. INLINEFORM0 INLINEFORM1 \nFor English punctuation, the evaluation is measured on each type of punctuation and overall F1 score. For the punctuation restoration task, we care only about the performance of the samples belonging to the classes that are tagged to words followed by punctuation; therefore class INLINEFORM0 , which represents words not immediately followed by punctuation, is ignored in the evaluation.

Adversarially trained network (Section A.7). CIFAR10 (Section A.6).\nNote also that, as also discussed with reviewer KEn1, the loss-gradient-only ablation figures have been added to Table 1.\nOriginally, we did not include any comparison against surrogate-free methods such as Square Attack since one of our competitors [2] (ODS) ran relevant experiments in their own paper, and claimed dramatic improvement over Square Attack in the L2-bound case (see Table 5 in that reference). Given that Square Attack does not use a surrogate, we did not find this result surprising. Since Square Attack was outright beaten by ODS-RGF in [2], and since we compare ourselves against ODS-RGF under the same experimental setup, we considered the Square Attack comparison to be redundant in our case. Having said that, we feel that this is nevertheless a worthwhile comparison, and have performed this experiment. We have revised the pdf of the submission to include SquareAttack in the main comparison of Fig.2 (a,b,c) and also in the comparison on targeted attack of Fig.4.\nWe are happy to cite the Bayesian optimisation approaches from a conceptual perspective, as part of the related work (along with latent-space methods we have already included such as AutoZOOM). However, we don’t see that these represent a competitive comparison. For one thing, both of the above papers present results only for the L_inf norm, and these results are not directly comparable to ours. Beyond this, the very low query counts achieved by [2] on the 0.05 l_inf bound on ImageNet come at the expense of far higher failure rates than the sort we are discussing here (ranging from about 20% to about 35%): The variant of the method that was eventually published (as “Simple and Efficient Hard Label Black-box Adversarial Attacks in Low Query Budget Regimes”) stays within the hard-label/decision-attack threat model, only comparing against other such methods. The performance of [1] is not comparable to ours or any of our chosen competitors: under the standard l_inf bound of 0.05 on ImageNet, their success rate is 60%, with a median query count of 1247. Note that the “state-of-the-art black-box methods” against which they compare are ZOO, AutoZOOM, and GenAttack.

Garfield both died within their first year in office, they are often omitted from presidential rankings. Zachary Taylor died after serving as president for only 16 months, but he is usually included.

        "evidence": "Deep learning is part of a broader family of machine learning methods based on artificial neural networks with representation learning. Learning can be supervised, semi-supervised or unsupervised.\n\nDeep-learning architectures such as deep neural networks, deep belief networks, deep reinforcement learning, recurrent neural networks, convolutional neural networks and transformers have been applied to fields including computer vision, speech recognition, natural language processing, machine translation, bioinformatics, drug design, medical image analysis, climate science, material inspection and board game programs, where they have produced results comparable to and in some cases surpassing human expert performance.\n\nArtificial neural networks (ANNs) were inspired by information processing and distributed communication nodes in biological systems. ANNs have various differences from biological brains. Specifically, artificial neural networks tend to be static and symbolic, while the biological brain of most living organisms is dynamic (plastic) and analog.\n\nThe adjective \"deep\" in deep learning refers to the use of multiple layers in the network. Early work showed that a linear perceptron cannot be a universal classifier, but that a network with a nonpolynomial activation function with one hidden layer of unbounded width can. Deep learning is a modern variation that is concerned with an unbounded number of layers of bounded size, which permits practical application and optimized implementation, while retaining theoretical universality under mild conditions. In deep learning the layers are also permitted to be heterogeneous and to deviate widely from biologically informed connectionist models, for the sake of efficiency, trainability and understandability.",

Ideally, they should also have 1 - 2 days a week when they don’t eat. This is because they have slow digestive systems and need a clear day or two for their systems to catch up. \n\nYou should give your tortoise a weekly supplement of calcium and D3.

        "evidence": "",
        "answer": "Tubeless tire installs require some setup. It's best to have experience with bicycle tires, and in particular, the use of tire levers to remove and install tires. Make sure your tires and rims are tubeless ready. If the manufacturer also provides a tubeless tape, use that, or use a generic brand. You'll also need sealant and a tubeless stem. The stem might require a tool to unscrew the nozzle for adding sealant. You'll also need a large syringe if you plan on using the stem to add sealant. You'll want a electronic pump, or a manual pump with a reservoir.\n\nI have found that larger tires are easier to install as tubeless but road tires can also be tubeless. The first step is to clean the rim and install tubeless tape around the rim. This should seal the rim component. You'll need to punch a hole for the stem and insert the stem. Next you'll need to lever the tire onto the rim, first one side, then both. If you don't have a syringe, you can add some sealant at this step before fully installing the tire. For road tires, I've found this method prone to spilling.\n\nNext, remove the core / nozzle from the tire stem and hook the stem up to your pump. You want to inject air into the tire quickly and at high pressure to \"set\" the beads of the tire against the rim. This should result in a popping sound. When you remove the pump, the tire will deflate since you removed the core. If you haven't already, add sealant at this step using a syringe, then reinstall the core and pump up the tire. I usually rotate the tire a bit, then flip it periodically while testing if it holds air. If it does you are done. Happy riding!",

According to BIBREF0, complaint is considered to be a basic speech act used to express negative mismatch between the expectation and reality.

Many transport organizations rely on complaints gathered via these platforms to improve their services, hence understanding these are important for: (1) linguists to identify human expressions of criticism and (2) organizations to improve their query response time and address concerns effectively.\nPresence of inevitable noise, sparse content along with rephrased and structurally morphed instances of posts, make the task at hand difficult BIBREF1. Previous works BIBREF2 in the domain of complaint extraction have focused on static datasets only. These are not robust to changes in the trends reflected, information flow and linguistic variations. We propose an iterative, semi-supervised approach for identification of complaint based tweets, having the ability to be replicated for stream of information flow. The preference of a semi-supervised approach over supervised ones is due to the stated reasons: (a) the task of isolating the training set, make supervised tasks less attractive and impractical and (b) imbalance between the subjective and objective classes lead to poor performance.\nWe propose an iterative, semi-supervised approach for identification of complaint based tweets, having the ability to be replicated for “stream of information flow”.",

There’s also a procedure called electron-beam computed tomography (EBCT) which can detect calcium deposits in arteries. There’s also computed tomography angiography which reveals plaque or calcium deposits. We can perform a coronary MRI or MRA, which uses magnetic fields to detect valve problems, heart enlargement, vessel disease, damaged heart tissue, etc. Finally, we can also perform a coronary angiogram, which is invasive, but is the “gold standard” for diagnosing CAD. There are interventions available to Jing, which range from less invasive/intense to most intense. He can do daily things like reduce his high alcohol consumption, eat a heart-healthier and less inflammatory diet to help his cholesterol and triglyceride levels. There are also some medications to treat myocardial ischemia such as a daily aspirin, nitrates, beta blockers, cholesterol-lowering medications, etc. If his situation is very serious/deteriorates, he can consider angioplasty/stenting, or even coronary artery bypass surgery.

This paper presents the contributions from the Cambridge University Engineering Department to the latest GEC competition at the BEA 2019 workshop.\nWe submitted systems to two different tracks. The low-resource track did not permit the use of parallel training data except a small development set with around 4K sentence pairs. For our low-resource system we extended our prior work on finite state transducer based GEC BIBREF3 to handle new error types such as punctuation errors as well as insertions and deletions of a small number of frequent words. For the restricted track, the organizers provided 1.2M pairs (560K without identity mappings) of corrected and uncorrected sentences. Our goal on the restricted track was to explore the potential of purely neural models for grammatical error correction. We confirm the results of BIBREF4 and report substantial gains by applying back-translation BIBREF5 to GEC – a data augmentation technique common in machine translation. Furthermore, we noticed that large parts of the training data do not match the target domain.

As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere.\nThe time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed.\nSunset is distinct from twilight, which is divided into three stages. The first one is civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon. The second phase is nautical twilight, between 6 and 12 degrees below the horizon. The third phase is astronomical twilight, which is the period when the Sun is between 12 and 18 degrees below the horizon. Dusk is at the very end of astronomical twilight, and is the darkest moment of twilight just before night. Finally, night occurs when the Sun reaches 18 degrees below the horizon and no longer illuminates the sky.\nLocations further north than the Arctic Circle and further south than the Antarctic Circle experience no full sunset or sunrise on at least one day of the year, when the polar day or the polar night persists continuously for 24 hours.",

A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office.\n\nThe 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that \"the IHDI is the actual level of human development (accounting for inequality), while the HDI can be viewed as an index of 'potential' human development (or the maximum level of HDI) that could be achieved if there were no inequality.\"\n\nThe index is based on the human development approach, developed by Mahbub ul Haq, anchored in Amartya Sen's work on human capabilities, and often framed in terms of whether people are able to \"be\" and \"do\" desirable things in life. Examples include – being: well fed, sheltered, and healthy; doing: work, education, voting, participating in community life. The freedom of choice is central – someone choosing to be hungry (e.g. when fasting for religious reasons) is quite different from someone who is hungry because they cannot afford to buy food, or because the country is in a famine.\n\nThe index does not take into account several factors, such as the net wealth per capita or the relative quality of goods in a country. This situation tends to lower the ranking of some of the most developed countries, such as the G7 members and others.",

        "evidence": "By 1927, Fleming had been investigating the properties of staphylococci. He was already well known from his earlier work, and had developed a reputation as a brilliant researcher. In 1928, he studied the variation of Staphylococcus aureus grown under natural condition, after the work of Joseph Warwick Bigger, who discovered that the bacterium could grow into a variety of types (strains). On 3 September 1928, Fleming returned to his laboratory having spent a holiday with his family at Suffolk. Before leaving for his holiday, he inoculated staphylococci on culture plates and left them on a bench in a corner of his laboratory. On his return, Fleming noticed that one culture was contaminated with a fungus, and that the colonies of staphylococci immediately surrounding the fungus had been destroyed, whereas other staphylococci colonies farther away were normal, famously remarking \"That's funny\". Fleming showed the contaminated culture to his former assistant Merlin Pryce, who reminded him, \"That's how you discovered lysozyme.\" He identified the mould as being from the genus Penicillium. He suspected it to be P. chrysogenum, but a colleague Charles J. La Touche identified it as P. rubrum. (It was later corrected as P. notatum and then officially accepted as P. chrysogenum; in 2011, it was resolved as P. rubens.)\nThe laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington. The source of the fungal contaminant was established in 1966 as coming from La Touche's room, which was directly below Fleming's.\nFleming grew the mould in a pure culture and found that the culture broth contained an antibacterial substance. He investigated its anti-bacterial effect on many organisms, and noticed that it affected bacteria such as staphylococci and many other Gram-positive pathogens that cause scarlet fever, pneumonia, meningitis and diphtheria, but not typhoid fever or paratyphoid fever, which are caused by Gram-negative bacteria, for which he was seeking a cure at the time. It also affected Neisseria gonorrhoeae, which causes gonorrhoea, although this bacterium is Gram-negative. After some months of calling it \"mould juice\" or \"the inhibitor\", he gave the name penicillin on 7 March 1929 for the antibacterial substance present in the mould.",
        "answer": "Penicillin has an anti-bacterial effect of a number of Gram-positive bacteria including but not limited to the bacteria that cause meningitis, diptheria, pneumonia, scarlet fever.  It also acts on (Gram-positive) staphylococci bacteria which cause skin and soft tissue infections such as boils.  Penicillin was also found to have an anti-bacterial action on the Gram-negative bacteria which causes gonorrhoea.  There were a series of fortuitous circumstances which combined to allow the discovery of penicillin, one of which was Sir Alexander's choice to take a holiday with his family after leaving staphylococci bacteria in a culture in his lab before departure.  Anecdotally Sir Alexander was a little sloppy with lab hygiene which contributed to his previous discovery of lysozyme and it seems the same lack of care was partly responsible for the discovery of penicillin.  Lastly the specific location of his lab and cultures played a role - the fungal contaminant that had an anti-bacterial effect on the staphylococci culture came from Sir Alexander's colleagues lab one floor below",

        "evidence": "It is common knowledge in modern NLP that using large amounts of high-quality training data is a key aspect in building successful machine-learning based systems. For this reason, a major challenge when building such systems is obtaining data in the domain of interest. But what defines a domain? Natural language varies greatly across topics, styles, levels of formality, genres and many other linguistic nuances BIBREF0, BIBREF1, BIBREF2. This overwhelming diversity of language makes it hard to find the right data for the task, as it is nearly impossible to well-define the exact requirements from such data with respect to all the aforementioned aspects. On top of that, domain labels are usually unavailable – e.g. in large-scale web-crawled data like Common Crawl which was recently used to train state-of-the-art pretrained language models for various tasks BIBREF3.\nDomain data selection is the task of selecting the most appropriate data for a domain from a large corpus given a smaller set of in-domain data BIBREF4, BIBREF5, BIBREF6, BIBREF7. In this work, we propose to use the recent, highly successful self-supervised pre-trained language models, e.g. devlin-etal-2019-bert,liu2019roberta for domain data selection. As pretrained LMs demonstrate state-of-the-art performance across many NLP tasks after being trained on massive amounts of data, we hypothesize that the robust representations they learn can be useful for mapping sentences to domains in an unsupervised, data-driven approach. We show that these models indeed learn to cluster sentence representations to domains without further supervision (e.g. Figure FIGREF2), and quantify this phenomenon by fitting Gaussian Mixture Models (GMMs) to the learned representations and measuring the purity of the resulting unsupervised clustering. We then propose methods to leverage these emergent domain clusters for domain data selection in two ways:\nVia distance-based retrieval in the sentence embedding space induced by the pretrained language model.\nBy fine-tuning the pretrained language model for binary classification, where positive examples are from the domain of interest.\nOur methods enable to select relevant data for the task while requiring only a small set of monolingual in-domain data. As they are based solely on the representations learned by self-supervised LMs, they do not require additional domain labels which are usually vague and over-simplify the notion of domain in textual data. We evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8. Our data selection methods enable to train NMT models that outperform those trained using the well-established cross-entropy difference method of BIBREF4 across five diverse domains, achieving a recall of more than 95% in all cases with respect to an oracle that selects the “true” in-domain data.\nOur contributions in this work are as follows. First, we show that pre-trained language models are highly capable of clustering textual data to domains with high accuracy in a purely unsupervised manner. Second, we propose methods to select in-domain data based on this property using vector-space retrieval and positive-unlabeled fine-tuning of pretrained language models for binary classification. Third, we show the applicability of our proposed data selection methods on a popular benchmark for domain adaptation in machine translation. An additional contribution is a new, improved data split we create for this benchmark, as we point on issues with previous splits used in the literature. The code and data for this work is publicly available. We hope this work will encourage more research on understanding the data landscape in NLP, enabling to “find the right data for the task” in the age of massive models and diverse data sources.\nWe evaluate our method on data selection for neural machine translation (NMT) using the multi-domain German-English parallel corpus composed by BIBREF8.",

Defining $l$ as the number of different language varieties, and $n$ the number of terms of the document to be classified, the cost of obtaining the features of Table 2 (average, minimum, maximum, probability and proportionality) is $O(l\\cdot {n})$ . Defining $m$ as the number of terms in the document that coincides with some term in the vocabulary, the cost of obtaining the standard deviation is $O(l\\cdot {m})$ . As the average is needed previously to the standard deviation calculation, the total cost is $O(l\\cdot {n}) + O(l\\cdot {m})$ that is equal to $O(max(l\\cdot {n}, l\\cdot {m})) =\nO(l\\cdot {n})$ . Since the number of terms in the vocabulary will always be equal or greater than the number of coincident terms ( $n \\ge m$ ), and as the number of terms in the document will always be much higher than the number of language varieties ( $l<<n$ ), we can determine the cost as lineal with respect to the number of terms in the document $O(n)$ . With respect to the number of features needed to represent a document, we showed in Table 6 the considerable reduction of the proposed low dimensionality representation.\nWe analyse the cost from two perspectives: i) the complexity to the features; and ii) the number of features needed to represent a document.",

Water occurs as both \"stocks\" and \"flows\". Water can be stored as lakes, water vapor, groundwater or aquifers, and ice and snow. Of the total volume of global freshwater, an estimated 69 percent is stored in glaciers and permanent snow cover; 30 percent is in groundwater; and the remaining 1 percent in lakes, rivers, the atmosphere, and biota. The length of time water remains in storage is highly variable: some aquifers consist of water stored over thousands of years but lake volumes may fluctuate on a seasonal basis, decreasing during dry periods and increasing during wet ones. A substantial fraction of the water supply for some regions consists of water extracted from water stored in stocks, and when withdrawals exceed recharge, stocks decrease. By some estimates, as much as 30 percent of total water used for irrigation comes from unsustainable withdrawals of groundwater, causing groundwater depletion.",

We investigate the role of shallow syntax-aware representations for NLP tasks using two techniques.

Our second method involves shallow syntactic features obtained automatically on downstream task data. Neither approach leads to a significant gain on any of the four downstream tasks we considered relative to ELMo-only baselines. Further analysis using black-box probes confirms that our shallow-syntax-aware contextual embeddings do not transfer to linguistic tasks any more easily than ELMo's embeddings. We take these findings as evidence that ELMo-style pretraining discovers representations which make additional awareness of shallow syntax redundant.\nFirst, we enhance the ELMo architecture (Peters et al.,2018b) to allow pretraining on predicted shallow syntactic parses, instead of just raw text, so that contextual embeddings make use of shallow syntactic context.

        "question": "How to generate a final summary?",
        "answer": "After estimating the sentence salience, the authors employ a phrase based compressive unified optimization framework to generate a final summary.",
        "evidence": "The goal of multi-document summarization (MDS) is to automatically generate a brief, well-organized summary for a topic which describes an event with a set of documents from different sources. BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 , BIBREF6 . In the typical setting of MDS, the input is a set of news documents about the same topic. The output summary is a piece of short text document containing several sentences, generated only based on the input original documents.\nWith the development of social media and mobile equipments, more and more user generated content is available. Figure FIGREF2 is a snapshot of reader comments under the news report “The most important announcements from Google's big developers' conference”. The content of the original news report talks about some new products based on AI techniques. The news report generally conveys an enthusiastic tone. However, while some readers share similar enthusiasms, some others express their worries about new products and technologies and these comments can also reflect their interests which may not be very salient in the original news reports. Unfortunately, existing MDS approaches cannot handle this issue. We investigate this problem known as reader-aware multi-document summarization (RA-MDS). Under the RA-MDS setting, one should jointly consider news documents and reader comments when generating the summaries.\nOne challenge of the RA-MDS problem is how to conduct salience estimation by jointly considering the focus of news reports and the reader interests revealed by comments. Meanwhile, the model should be insensitive to the availability of diverse aspects of reader comments. Another challenge is that reader comments are very noisy, not fully grammatical and often expressed in informal expressions. Some previous works explore the effect of comments or social contexts in single document summarization such as blog summarization BIBREF7 , BIBREF8 . However, the problem setting of RA-MDS is more challenging because the considered comments are about an event which is described by multiple documents spanning a time period. Another challenge is that reader comments are very diverse and noisy. Recently, BIBREF9 employed a sparse coding based framework for RA-MDS jointly considering news documents and reader comments via an unsupervised data reconstruction strategy. However, they only used the bag-of-words method to represent texts, which cannot capture the complex relationship between documents and comments.\nRecently, BIBREF6 proposed a sentence salience estimation framework known as VAESum based on a neural generative model called Variational Auto-Encoders (VAEs) BIBREF10 , BIBREF11 . During our investigation, we find that the Gaussian based VAEs have a strong ability to capture the salience information and filter the noise from texts. Intuitively, if we feed both the news sentences and the comment sentences into the VAEs, commonly existed latent aspect information from both of them will be enhanced and become salient. Inspired by this consideration, to address the sentence salience estimation problem for RA-MDS by jointly considering news documents and reader comments, we extend the VAESum framework by training the news sentence latent model and the comment sentence latent model simultaneously by sharing the neural parameters. After estimating the sentence salience, we employ a phrase based compressive unified optimization framework to generate a final summary.\nThere is a lack of high-quality dataset suitable for RA-MDS. Existing datasets from DUC and TAC are not appropriate. Therefore, we introduce a new dataset for RA-MDS. We employed some experts to conduct the tasks of data collection, aspect annotation, and summary writing as well as scrutinizing. To our best knowledge, this is the first dataset for RA-MDS.\nOur contributions are as follows: (1) We investigate the RA-MDS problem and introduce a new dataset for the problem of RA-MDS. To our best knowledge, it is the first dataset for RA-MDS. (2) To tackle the RA-MDS, we extend a VAEs-based MDS framework by jointly considering news documents and reader comments. (3) Experimental results show that reader comments can improve the summarization performance, which also demonstrates the usefulness of the dataset.\nAfter estimating the sentence salience, we employ a phrase based compressive unified optimization framework to generate a final summary.",

        "evidence": "Disclaimer: Due to the nature of the paper, some examples contain highly offensive language and hate speech. They don't reflect the views of the authors in any way, and the point of the paper is to help fight such speech. Much recent interest has focused on the detection of offensive language and hate speech in online social media. Such language is often associated with undesirable online behaviors such as trolling, cyberbullying, online extremism, political polarization, and propaganda. Thus, offensive language detection is instrumental for a variety of application such as: quantifying polarization BIBREF0, BIBREF1, trolls and propaganda account detection BIBREF2, detecting the likelihood of hate crimes BIBREF3; and predicting conflict BIBREF4. In this paper, we describe our methodology for building a large dataset of Arabic offensive tweets. Given that roughly 1-2% of all Arabic tweets are offensive BIBREF5, targeted annotation is essential for efficiently building a large dataset. Since our methodology does not use a seed list of offensive words, it is not biased by topic, target, or dialect. Using our methodology, we tagged 10,000 Arabic tweet dataset for offensiveness, where offensive tweets account for roughly 19% of the tweets. Further, we labeled tweets as vulgar or hate speech. To date, this is the largest available dataset, which we plan to make publicly available along with annotation guidelines. We use this dataset to characterize Arabic offensive language to ascertain the topics, dialects, and users' gender that are most associated with the use of offensive language. Though we suspect that there are common features that span different languages and cultures, some characteristics of Arabic offensive language is language and culture specific. Thus, we conduct a thorough analysis of how Arabic users use offensive language. Next, we use the dataset to train strong Arabic offensive language classifiers using state-of-the-art representations and classification techniques. Specifically, we experiment with static and contextualized embeddings for representation along with a variety of classifiers such as a deep neural network classifier and Support Vector Machine (SVM).\nThe contributions of this paper are as follows:\nWe built the largest Arabic offensive language dataset to date that includes special tags for vulgar language and hate speech.

Updates to the software are often included in the price of the subscription.  At the end of the subscription term, the buyer usually has the option to renew their subscription.\n\nConsumption-based software allows the buyer to pay for their actual usage of the software during a period of time, for example monthly.

        "question": "What are the axioms in the OWL?",
        "answer": "Axioms are statements that are asserted to be true in the domain being described.",
        "evidence": "OWL BIBREF15 is the de-facto standard for machine processable and interoperable ontologies on the SW. In its second version, OWL is equivalent to the description logic $\\mathcal {SROIQ}(D)$. Such expressiveness has a higher computational cost but allows the development of interesting applications such as automated reasoning BIBREF16. OWL 2 ontologies consist of the following three different syntactic categories:\nEntities, such as classes, properties, and individuals, are identified by IRIs. They form the primitive terms and constitute the basic elements of an ontology. Classes denote sets of individuals and properties link two individuals or an individual and a data value along a property. For example, a class :Animal can be used to represent the set of all animals. Similarly, the object property :childOf can be used to represent the parent-child relationship and the data property :birthDate assigns a particular birth date to an individual. Finally, the individual :Alice can be used to represent a particular person called \"Alice\".\nExpressions represent complex notions in the domain being described. For example, a class expression describes a set of individuals in terms of the restrictions on the individuals' characteristics. OWL offers existential (SOME) or universal (ONLY) qualifiers and a variety of typical logical constructs, such as negation (NOT), other Boolean operators (OR, AND), and more constructs such as cardinality restriction (MIN, MAX, EXACTLY) and value restriction (VALUE), to create class expressions. Such constructs can be combined in arbitrarily complex class expressions CE according to the following grammar\nwhere A is an atomic class, C and D are class expressions, R is an object property, a as well as a$_1$ to a$_m$ with $\\texttt {m} \\ge 1$ are individuals, and $\\texttt {n} \\ge 0$ is an integer.\nAxioms are statements that are asserted to be true in the domain being described. Usually, one distinguish between (1) terminological and (2) assertional axioms. (1) terminological axioms are used to describe the structure of the domain, i.e., the relationships between classes resp. class expressions. For example, using a subclass axiom (SubClassOf:), one can state that the class :Koala is a subclass of the class :Animal. Classes can be subclasses of other classes, thus creating a taxonomy. In addition, axioms can arrange properties in hierarchies (SubPropertyOf:) and can assign various characteristics (Characteristics:) such as transitivity or reflexivity to them. (2) Assertional axioms formulate facts about individuals, especially the classes they belong to and their mutual relationships. OWL can be expressed in various syntaxes with the most common computer readable syntax being RDF/XMLA more human-readable format is the MOS BIBREF17. For example, the class expression that models people who work at a university that is located in Spain could be as follows in MOS:\nLikewise, expressing that every professor works at a university would read as\nOWL 2 ontologies consist of Entities, Expressions and Axioms as introduced in subsec:owl. While both expressions and axioms can be mapped to RDF, i.e. into a set of RDF triples, using this mapping and applying the triple-based verbalization on it would lead to a non-human understandable text in many cases. For example, the intersection of two classes :A and :B can be represented in RDF by the six triples\nThe verbalization of these triples would result in Something that is a class and the intersection of something whose first is A and whose rest is something whose first is B and whose rest ist nil., which is obviously far away from how a human would express it in NL. Therefore, generating NL from OWL requires a different procedure based on its syntactic categories, OWL expressions and OWL axioms. We show the general rules for each of them in the following.\nIn theory, class expressions can be arbitrarily complex, but as it turned out in some previous analysis BIBREF22, in practice they seldom arise and can be seen as some corner cases. For example, an ontology could contain the following class expression about people and their birth place:\nClass expressions do have a tree-like structure and can simply be parsed into a tree by means of the binary OWL class expressions constructors contained in it. For our example, this would result in the following tree:\nevery tree node/.style=align=center,anchor=base,font=, edge from parent/.style= thick, draw, edge from parent path=(.south) – +(0,-8pt) -| () frontier/.style=distance from root=9 [.AND Person [.SOME birthPlace [.AND City [.VALUE locatedIn France ] ] ] ]\nSuch a tree can be traversed in post-order, i.e. sub-trees are processed before their parent nodes recursively. For the sake of simplicity, we only process sub-trees that represent proper class expression in our example, i.e. we omit birthPlace, locatedIn, and France. Moreover and again for simplicity, we'll explain the transformation process by starting from the right-hand side of the tree. Thus, in our example we begin with the class expression City which is transformed to everything that is a city and locatedIn VALUE France resulting in everything that is located in France by application of a rule. Both class expressions are used in the conjunction City AND locatedIn VALUE France. Thus, the next step would be to merge both phrases. An easy way is to use the coordinating conjunction and, i.e. everything that is a city and everything that is located in France. Although the output of this transformation is correct, it still contains unnecessarily redundant information. Therefore, we apply the aggregation procedure described in subsec:grouping, i.e. we get everything that is a city and located in France. Yet, the aggregation can still be improved: if there is any atomic class in the conjunction, we know that this is more specific than the placeholder everything. Thus, we can replace it by the plural form of the class, finally resulting in cities that are located in France. The same procedure is applied for its parent class expression being the existential restriction\nThis will be transformed to everything whose birth place is a city that is located in France. Note, that we used the singular form here, assuming that the property birthPlace is supposed to be functional in the ontology. In the last step, we process the class expression Person, which gives us everything that is a person. Again, due to the conjunction we merge this result with with the previous one, such that in the end we get people whose birth place is a city that is located in France.\nAs we described in sec:owl, OWL axioms can roughly be categorized into terminological and assertional axioms. Therefore, we have different procedures for processing each category:\nAssertional Axioms (ABox Axioms) - Most assertional axioms assert individuals to atomic classes or relate individuals to another individual resp. literal value. For example, axioms about the type as well as birth place and birth date of Albert Einstein can be expressed by\nThose axioms can simply be rewritten as triples, thus, we can use the same procedure as we do for triples (sec:singletriple). Converting them into NL gives us Albert Einstein is a person whose birth place is Ulm and whose birth date is 14 March 1879. OWL also allows for assigning an individual to a complex class expression. In that case we'll use our conversion of OWL class expressions as described in subsec:owlce.\nTerminological Axioms (TBox Axioms) - According to power2010, most of the terminological axioms used in ontologies are subclass axioms. By definition, subclass and superclass can be arbitrarily complex class expressions $\\texttt {CE}_1$ and $\\texttt {CE}_2$, i.e. [language=manchester,mathescape=true]CE$_1$ SubClassOf CE$_2$, but in praxis it is quite often only used with atomic classes as subclass or even more simple with the superclass also beeing an atomic class. Nevertheless, we support any kind of subclass axiom and all other logical OWL axioms in LD2NL. For simplicity, we outline here how we verbalize subclass axioms in LD2NL. The semantics of a subclass axiom denotes that every individual of the subclass also belongs to the superclass. Thus, the verbalization seems to be relatively straightforward, i.e. we verbalize both class expressions and follow the template : every $\\rho (\\texttt {\\texttt {CE}$1$})$ is a $\\rho (\\texttt {\\texttt {CE}$2$})$. Obviously, this works pretty well for subclass axioms with atomic classes only. For example, the axiom\nis verbalized as every scientist is a person.\nThis work was supported by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) through the projects LIMBO (no. 19F2029I) and OPAL (no. 19F2028A).

These works indirectly reduce repeating and missing words, while we directly penalize translation mismatch by considering back-translation.\nThe encoder-decoder-reconstructor framework for NMT proposed by tu2016neural optimizes NMT by reconstructor using back-translation.

In this regard, we observed that HDGAN produced relatively better visual results on the CUB and Oxford datasets while AttnGAN produced far more impressive results than the rest on the more complex COCO dataset.

The designs and advancement of DM-GAN and Obj-GAN indicate that research in text-to-image synthesis is advancing to put more emphasis on the image details and text semantics for better understanding and perception.\nIn this regard, we observed that HDGAN produced relatively better visual results on the CUB and Oxford datasets while AttnGAN produced far more impressive results than the rest on the more complex COCO dataset.\nIn terms of inception score (IS), which is the metric that was applied to majority models except DC-GAN, the results in Table TABREF48 show that StackGAN++ only showed slight improvement over its predecessor, StackGAN, for text-to-image synthesis.\nIn addition, the results in Table TABREF48 also show that DM-GAN BIBREF53 has the best performance, followed by Obj-GAN BIBREF81.

        "evidence": "Named entity recognition (NER) BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 is the process by which we identify text spans which mention named entities, and to classify them into predefined categories such as person, location, organization etc. NER serves as the basis for a variety of natural language processing (NLP) applications such as relation extraction BIBREF4 , machine translation BIBREF5 , question answering BIBREF6 and knowledge base construction BIBREF7 . Although early NER systems have been successful in producing adequate recognition accuracy, they often require significant human effort in carefully designing rules or features.\nIn recent years, deep learning methods been employed in NER systems, yielding state-of-the-art performance. However, the number of types detected are still not sufficient for certain domain-specific applications. For relation extraction, identifying fine-grained types has been shown to significantly increase the performance of the extractor BIBREF8 , BIBREF9 since this helps in filtering out candidate relation types which do not follow this type constraint. Furthermore, for question answering fine-grained Named Entity Recognition (FgNER) can provide additional information helping to match questions to its potential answers thus improving performance BIBREF10 . For example, Li and Roth BIBREF11 rank questions based on their expected answer types (i.e. will the answer be food, vehicle or disease).\nTypically, FgNER systems use over a hundred labels, arranged in a hierarchical structure. We find that available training data for FgNER typically contain noisy labels, and creating manually annotated training data for FgNER is a time-consuming process. Furthermore, human annotators will have to assign a subset of correct labels from hundreds of possible labels making this a somewhat arduous task. Currently, FgNER systems use distant supervision BIBREF12 to automatically generate training data. Distant supervision is a technique which maps each entity in the corpus to knowledge bases such as Freebase BIBREF13 , DBpedia BIBREF14 , YAGO BIBREF15 and helps with the generation of labeled data. This method will assign the same set of labels to all mentions of a particular entity in the corpus. For example, “Barack Obama” is a person, politician, lawyer, and author. If a knowledge base has these four matching labels, the distant supervision technique will assign all of them to every mention of “Barack Obama”. Therefore, the training data will also fail to distinguish between mentions of “Barack Obama” in all subsequent utterances.\nLing et al. ling2012fine proposed the first system for FgNER, where they used 112 overlapping labels with a linear classifier perceptron for multi-label classification. Yosef et al. spaniol2012hyena used multiple binary SVM classifiers to assign entities to a set of 505 types. Gillick et al. gillick2014context introduced context dependent FgNER and proposed a set of heuristics for pruning labels that might not be relevant given the local context of the entity. Yogatama et al. yogatama2015embedding proposed an embedding based model where user-defined features and labels were embedded into a low dimensional feature space to facilitate information sharing among labels.\nShimaoka et al. shimaoka2016attentive proposed an attentive neural network model which used long short-term memory (LSTMs) to encode the context of the entity, then used an attention mechanism to allow the model to focus on relevant expressions in the entity mention's context. To learn entity representations, we propose a scheme which is potentially more generalizable.\nCurrently, FgNER systems use distant supervision (Craven and Kumlien, 1999) to automatically generate training data.",

        "question": "What do the expressions represent in the OWL?",
        "answer": "Expressions represent complex notions in the domain being described.",
        "evidence": "OWL BIBREF15 is the de-facto standard for machine processable and interoperable ontologies on the SW. In its second version, OWL is equivalent to the description logic $\\mathcal {SROIQ}(D)$. Such expressiveness has a higher computational cost but allows the development of interesting applications such as automated reasoning BIBREF16. OWL 2 ontologies consist of the following three different syntactic categories:\nEntities, such as classes, properties, and individuals, are identified by IRIs. They form the primitive terms and constitute the basic elements of an ontology. Classes denote sets of individuals and properties link two individuals or an individual and a data value along a property. For example, a class :Animal can be used to represent the set of all animals. Similarly, the object property :childOf can be used to represent the parent-child relationship and the data property :birthDate assigns a particular birth date to an individual. Finally, the individual :Alice can be used to represent a particular person called \"Alice\".\nExpressions represent complex notions in the domain being described. For example, a class expression describes a set of individuals in terms of the restrictions on the individuals' characteristics. OWL offers existential (SOME) or universal (ONLY) qualifiers and a variety of typical logical constructs, such as negation (NOT), other Boolean operators (OR, AND), and more constructs such as cardinality restriction (MIN, MAX, EXACTLY) and value restriction (VALUE), to create class expressions. Such constructs can be combined in arbitrarily complex class expressions CE according to the following grammar\nwhere A is an atomic class, C and D are class expressions, R is an object property, a as well as a$_1$ to a$_m$ with $\\texttt {m} \\ge 1$ are individuals, and $\\texttt {n} \\ge 0$ is an integer.\nAxioms are statements that are asserted to be true in the domain being described. Usually, one distinguish between (1) terminological and (2) assertional axioms. (1) terminological axioms are used to describe the structure of the domain, i.e., the relationships between classes resp. class expressions. For example, using a subclass axiom (SubClassOf:), one can state that the class :Koala is a subclass of the class :Animal. Classes can be subclasses of other classes, thus creating a taxonomy. In addition, axioms can arrange properties in hierarchies (SubPropertyOf:) and can assign various characteristics (Characteristics:) such as transitivity or reflexivity to them. (2) Assertional axioms formulate facts about individuals, especially the classes they belong to and their mutual relationships. OWL can be expressed in various syntaxes with the most common computer readable syntax being RDF/XMLA more human-readable format is the MOS BIBREF17. For example, the class expression that models people who work at a university that is located in Spain could be as follows in MOS:\nLikewise, expressing that every professor works at a university would read as\nOWL 2 ontologies consist of Entities, Expressions and Axioms as introduced in subsec:owl. While both expressions and axioms can be mapped to RDF, i.e. into a set of RDF triples, using this mapping and applying the triple-based verbalization on it would lead to a non-human understandable text in many cases. For example, the intersection of two classes :A and :B can be represented in RDF by the six triples\nThe verbalization of these triples would result in Something that is a class and the intersection of something whose first is A and whose rest is something whose first is B and whose rest ist nil., which is obviously far away from how a human would express it in NL. Therefore, generating NL from OWL requires a different procedure based on its syntactic categories, OWL expressions and OWL axioms. We show the general rules for each of them in the following.\nIn theory, class expressions can be arbitrarily complex, but as it turned out in some previous analysis BIBREF22, in practice they seldom arise and can be seen as some corner cases. For example, an ontology could contain the following class expression about people and their birth place:\nClass expressions do have a tree-like structure and can simply be parsed into a tree by means of the binary OWL class expressions constructors contained in it. For our example, this would result in the following tree:\nevery tree node/.style=align=center,anchor=base,font=, edge from parent/.style= thick, draw, edge from parent path=(.south) – +(0,-8pt) -| () frontier/.style=distance from root=9 [.AND Person [.SOME birthPlace [.AND City [.VALUE locatedIn France ] ] ] ]\nSuch a tree can be traversed in post-order, i.e. sub-trees are processed before their parent nodes recursively. For the sake of simplicity, we only process sub-trees that represent proper class expression in our example, i.e. we omit birthPlace, locatedIn, and France. Moreover and again for simplicity, we'll explain the transformation process by starting from the right-hand side of the tree. Thus, in our example we begin with the class expression City which is transformed to everything that is a city and locatedIn VALUE France resulting in everything that is located in France by application of a rule. Both class expressions are used in the conjunction City AND locatedIn VALUE France. Thus, the next step would be to merge both phrases. An easy way is to use the coordinating conjunction and, i.e. everything that is a city and everything that is located in France. Although the output of this transformation is correct, it still contains unnecessarily redundant information. Therefore, we apply the aggregation procedure described in subsec:grouping, i.e. we get everything that is a city and located in France. Yet, the aggregation can still be improved: if there is any atomic class in the conjunction, we know that this is more specific than the placeholder everything. Thus, we can replace it by the plural form of the class, finally resulting in cities that are located in France. The same procedure is applied for its parent class expression being the existential restriction\nThis will be transformed to everything whose birth place is a city that is located in France. Note, that we used the singular form here, assuming that the property birthPlace is supposed to be functional in the ontology. In the last step, we process the class expression Person, which gives us everything that is a person. Again, due to the conjunction we merge this result with with the previous one, such that in the end we get people whose birth place is a city that is located in France.\nAs we described in sec:owl, OWL axioms can roughly be categorized into terminological and assertional axioms. Therefore, we have different procedures for processing each category:\nAssertional Axioms (ABox Axioms) - Most assertional axioms assert individuals to atomic classes or relate individuals to another individual resp. literal value. For example, axioms about the type as well as birth place and birth date of Albert Einstein can be expressed by\nThose axioms can simply be rewritten as triples, thus, we can use the same procedure as we do for triples (sec:singletriple). Converting them into NL gives us Albert Einstein is a person whose birth place is Ulm and whose birth date is 14 March 1879. OWL also allows for assigning an individual to a complex class expression. In that case we'll use our conversion of OWL class expressions as described in subsec:owlce.\nTerminological Axioms (TBox Axioms) - According to power2010, most of the terminological axioms used in ontologies are subclass axioms. By definition, subclass and superclass can be arbitrarily complex class expressions $\\texttt {CE}_1$ and $\\texttt {CE}_2$, i.e. [language=manchester,mathescape=true]CE$_1$ SubClassOf CE$_2$, but in praxis it is quite often only used with atomic classes as subclass or even more simple with the superclass also beeing an atomic class. Nevertheless, we support any kind of subclass axiom and all other logical OWL axioms in LD2NL. For simplicity, we outline here how we verbalize subclass axioms in LD2NL. The semantics of a subclass axiom denotes that every individual of the subclass also belongs to the superclass. Thus, the verbalization seems to be relatively straightforward, i.e. we verbalize both class expressions and follow the template : every $\\rho (\\texttt {\\texttt {CE}$1$})$ is a $\\rho (\\texttt {\\texttt {CE}$2$})$. Obviously, this works pretty well for subclass axioms with atomic classes only. For example, the axiom\nis verbalized as every scientist is a person.\nThis work was supported by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) through the projects LIMBO (no. 19F2029I) and OPAL (no. 19F2028A).

        "question": "Which attracted the largest number of outliers?",
        "answer": "IT domain cluster.",
        "evidence": "As can be seen in Figure FIGREF15, in some areas the domains are somewhat overlapping in the embedding space, which may lead to outlier cases where examples from one domain are assigned to a cluster of a another domain. We plot a confusion matrix (Figure FIGREF20) to analyze this further based on the clustering with BERT-base and k=5. We first note that the outlier sentences are much shorter than the average sentence length in the corpus (11.62 tokens on average for outliers vs. 20.5 tokens on average in general). This makes sense as shorter sentences contain less information, making it harder to assign them to an appropriate cluster. Table TABREF19 shows examples of outlier sentences, assigned to clusters of domains different from their originating domain. We can see that in many cases the assignments are sensible – for example for sentences originating from the subtitles corpus, a sentence that mentions “great priest” is assigned to the Koran cluster, a sentence that mentions “The International Criminal Court in The Hague” is assigned to the Law cluster, a sentence that mentions “the virus” is assigned to the Medical cluster and so on. This strengthens our claim that defining domains based on the corpus they originated from may be over-simplistic, and using a more data-driven approach may enable to find better domain assignments across different corpora.\nThe domain that attracted the largest number of outliers is the IT domain cluster, with 597 sentences assigned to it from other domains. Looking more closely we find that more than half of these sentences (340 out of 597) included numbers (e.g. “34% 25% 34%” (from medical), “(b) reference number 20 is deleted;” (from law), “(Command of Prostration # 1)” (from Koran) or “The message, R2.” (from subtitles)). As numbers appear in many different contexts, they may be harder to assign to a specific domain by the context-aware language models in such short sentences. The second largest attractor of outliers is the Subtitles cluster, with 372 sentences assigned to it from other domains. We find that most of these sentences contain personal pronouns or question marks (228 out of 372, 61.2%) while the ratio of such sentences in the entire corpus is only 40%. Examples include “Why did you choose the name & amarok;?” (from IT), or “What is Avonex?” (from Medical). This may be expected as the subtitles corpus mainly includes transcriptions of spoken, conversational language, and “conversation tends to have more verbs, more personal pronouns, and more questions” BIBREF25. Another possible reason for the subtitles domain to attract outliers is the fact that this is the least-topical cluster: movies and TV series may discuss diverse topics, unlike medical, religious, legal and technical texts that may have a more cohesive topic.\nWe perform an analysis on the selected datasets, where we measure the precision and recall of sentence selection with respect to the oracle selection. The results are available in Table TABREF34. As also reflected in the BLEU scores, the Domain-Finetune method resulted in the highest domain recall with a minimum of 97.5, while Moore-Lewis and Domain-Cosine scored 89.4 and 78.8 respectively. We find these results very appealing given that only 2000 in-domain sentences were used for selection for each domain out of 1.45 million sentences. Also note that we used DistilBERT in these experiments: we believe that using larger, non-distilled models may result in even better selection performance (although at the price of larger computational requirements).\npx\nThe domain that attracted the largest number f outliers is the IT domain cluster, with 597 sentences assigned to it from other domains.",

Twice was formed under the television program Sixteen (2015) and debuted on October 20, 2015, with the extended play (EP) The Story Begins.\n\nTwice rose to domestic fame in 2016 with their single \"Cheer Up\", which charted at number one on the Gaon Digital Chart, became the best-performing single of the year, and won \"Song of the Year\" at the Melon Music Awards and Mnet Asian Music Awards. Their next single, \"TT\", from their third EP Twicecoaster: Lane 1, topped the Gaon charts for four consecutive weeks. The EP was the highest selling Korean girl group album of 2016. Within 19 months after debut, Twice had already sold over 1.2 million units of their four EPs and special album. As of December 2020, the group has sold over 15 million albums cumulatively in South Korea and Japan.\n\nThe group debuted in Japan on June 28, 2017, under Warner Music Japan, with the release of a compilation album titled #Twice. The album charted at number 2 on the Oricon Albums Chart with the highest first-week album sales by a K-pop artist in Japan in two years. It was followed by the release of Twice's first original Japanese maxi single titled \"One More Time\" in October. Twice became the first Korean girl group to earn a platinum certification from the Recording Industry Association of Japan (RIAJ) for both an album and CD single in the same year. Twice ranked third in the Top Artist category of Billboard Japan's 2017 Year-end Rankings, and in 2019, they became the first Korean girl group to embark on a Japanese dome tour.\n\nTwice is the first female Korean act to simultaneously top both Billboard's World Albums and World Digital Song Sales charts with the release of their first studio album Twicetagram and its lead single \"Likey\" in 2017.

In Gigaword dataset where the texts are short, our best model achieves a comparable performance with the current state-of-the-art. In CNN dataset where the texts are longer, our best model outperforms all the previous models. We emphasize that E2T module is easily attachable to better models, and we expect E2T to improve their performance as well. Overall, E2T achieves a significant improvement over the baseline model base, with at least 2 ROUGE-1 points increase in the Gigaword dataset and 6 ROUGE-1 points increase in the CNN dataset. In fact, all variants of E2T gain improvements over the baseline, implying that leveraging on linked entities improves the performance of the summarizer. Among the model variants, the CNN-based encoder with selective disambiguation and firm attention performs the best.\nAutomatic evaluation on the Gigaword dataset shows that the CNN and RNN variants of base+E2T have similar performance. To break the tie between both models, we also conduct human evaluation on the Gigaword dataset. We instruct two annotators to read the input sentence and rank the competing summaries from first to last according to their relevance and fluency: (a) the original summary gold, and from models (b) base, (c) base+E2Tcnn, and (d) base+E2Trnn. We then compute (i) the proportion of every ranking of each model and (ii) the mean rank of each model. The results are reported in Table 4 . The model with the best mean rank is base+E2Tcnn, followed by gold, then by base+E2Trnn and base, respectively.

The RNN variant does not perform as well as the CNN variant, contrary to the automatic ROUGE evaluation above. Interestingly, the CNN variant produces better (but with no significant difference) summaries than the gold summaries.

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nAlthough supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platformbased metadata, they necessitate a well-defined feature extraction approach.",

The World Bank estimates that climate change could drive over 120 million people into poverty by 2030.\n\nCurrent inequalities based on wealth and social status have worsened due to climate change. Major difficulties in mitigating, adapting, and recovering to climate shocks are faced by marginalized people who have less control over resources. Indigenous people, who are subsistent on their land and ecosystems, will face endangerment to their wellness and lifestyles due to climate change. An expert elicitation concluded that the role of climate change in armed conflict has been small compared to factors such as socio-economic inequality and state capabilities.\n\nLow-lying islands and coastal communities are threatened by sea level rise, which makes flooding more common.

        "answer": "Yes.",
        "evidence": "In recent years, zero-shot translation in NMT has attracted widespread attention in academic research. Existing methods are mainly divided into four categories: pivot-based method, transfer learning, multilingual NMT, and unsupervised NMT.\nPivot-based Method is a common strategy to obtain a source$\\rightarrow $target model by introducing a pivot language. This approach is further divided into pivoting and pivot-synthetic. While the former firstly translates a source language into the pivot language which is later translated to the target language BIBREF4, BIBREF5, BIBREF12, the latter trains a source$\\rightarrow $target model with pseudo data generated from source-pivot or pivot-target parallel data BIBREF13, BIBREF14. Although the pivot-based methods can achieve not bad performance, it always falls into a computation-expensive and parameter-vast dilemma of quadratic growth in the number of source languages, and suffers from the error propagation problem BIBREF15.\nTransfer Learning is firstly introduced for NMT by BIBREF6, which leverages a high-resource parent model to initialize the low-resource child model. On this basis, BIBREF7 and BIBREF8 use shared vocabularies for source/target language to improve transfer learning, while BIBREF16 relieve the vocabulary mismatch by mainly using cross-lingual word embedding. Although these methods are successful in the low-resource scene, they have limited effects in zero-shot translation.\nMultilingual NMT (MNMT) enables training a single model that supports translation from multiple source languages into multiple target languages, even those unseen language pairs BIBREF17, BIBREF18, BIBREF19, BIBREF20, BIBREF21. Aside from simpler deployment, MNMT benefits from transfer learning where low-resource language pairs are trained together with high-resource ones. However, BIBREF22 point out that MNMT for zero-shot translation easily fails, and is sensitive to the hyper-parameter setting. Also, MNMT usually performs worse than the pivot-based method in zero-shot translation setting BIBREF23.\nUnsupervised NMT (UNMT) considers a harder setting, in which only large-scale monolingual corpora are available for training. Recently, many methods have been proposed to improve the performance of UNMT, including using denoising auto-encoder, statistic machine translation (SMT) and unsupervised pre-training BIBREF24, BIBREF25, BIBREF26, BIBREF11. Since UNMT performs well between similar languages (e.g., English-German translation), its performance between distant languages is still far from expectation.\nOur proposed method belongs to the transfer learning, but it is different from traditional transfer methods which train a parent model as starting point. Before training a parent model, our approach fully leverages cross-lingual pre-training methods to make all source languages share the same feature space and thus enables a smooth transition for zero-shot translation.\nAlso, MNMT usually performs worse than the pivot-based method in zero-shot translation setting (Arivazhagan et al. 2018).",

        "evidence": "Question answering on tabular data is an important problem in natural language processing. Recently, a number of systems have been proposed for solving the problem using the WikiTableQuestions dataset BIBREF1 (henceforth called WTQ). This dataset consists of triples of the form INLINEFORM0 question, table, answer INLINEFORM1 where the tables are scraped from Wikipedia and questions and answers are gathered via crowdsourcing. The dataset is quite challenging, with the current best model BIBREF0 (henceforth called KDG) achieving a single model accuracy of only 43.3% . This is nonetheless a significant improvement compared to the 34.8% accuracy achieved by the previous best single model BIBREF2 .\nWe sought to analyze the source of the improvement achieved by the KDG model. The KDG paper claims that the improvement stems from certain aspects of the model architecture.\nIn this paper, we find that a large part of the improvement also stems from a certain pruning of the data used to train the model. The KDG system generates its training data using an algorithm proposed by BIBREF3 . This algorithm applies a pruning step (discussed in Section SECREF3 ) to eliminate spurious training data entries. We find that without this pruning of the training data, accuracy of the KDG model drops to 36.3%. We consider this an important finding as the pruning step not only accounts for a large fraction of the improvement in the state-of-the-art KDG model but may also be relevant to training other models. In what follows, we briefly discuss the pruning algorithm, how we identified its importance for the KDG model, and its relevance to further work.\nThis algorithm applies a pruning step (discussed in Section SECREF3 ) to eliminate spurious training data entries.",

        "answer": "Yes, they did.",
        "evidence": "The experimental results of the detection task and the generative intervention task are shown in Table TABREF27 and Table TABREF29 separately. The results of the human evaluation are shown in Table TABREF30. Figure FIGREF25 shows examples of the generated responses.\nAs shown in Table TABREF27 and TABREF29, all the classification and generative models perform better on the Gab dataset than on the Reddit dataset. We think this stems from the datasets' characteristics. First, the Gab dataset is larger and has a more balanced category distribution than the Reddit dataset. Therefore, it is inherently more challenging to train a classifier on the Reddit dataset. Further, the average lengths of the Reddit posts and conversations are much larger than those of Gab, potentially making the Reddit input nosier than the Gab input for both tasks. On both the Gab and Reddit datasets, the SVM classifier and the LR classifier achieved better performance than the CNN and RNN model with randomly initialized word embeddings. A possible reason is that without pretrained word embeddings, the neural network models tend to overfit on the dataset.\nFor the generative intervention task, three models perform similarly on all three automatic evaluation metrics. As expected, the Seq2Seq model achieves higher scores with filtered conversation as input. However, this is not the case for the VAE model. This indicates that the two models may have different capabilities to capture important information in conversations.\nAs shown in Table TABREF29, applying Reinforcement Learning does not lead to higher scores on the three automatic metrics. However, human evaluation (Table TABREF30) shows that the RL model creates responses that are potentially better at mitigating hate speech and are more diverse, which is consistent with BIBREF21. There is a larger performance difference with the Gab dataset, while the effectiveness and the diversity of the responses generated by the Seq2Seq model and the RL model are quite similar on the Reddit dataset. One possible reason is that the size of the training data from Reddit (around 8k) is only 30% the size of the training data from Gab. The inconsistency between the human evaluation results and the automatic ones indicates the automatic evaluation metrics listed in Table TABREF29 can hardly reflect the quality of the generated responses. As mentioned in Section SECREF4, annotators tend to have strategies for intervention. Therefore, generating the common parts of the most popular strategies for all the testing input can lead to high scores of these automatic evaluation metrics. For example, generating “Please do not use derogatory language.” for all the testing Gab data can achieve 4.2 on BLEU, 20.4 on ROUGE, and 18.2 on METEOR. However, this response is not considered as high-quality because it is almost a universal response to all the hate speech, regardless of the context and topic.\nSurprisingly, the responses generated by the VAE model have much worse diversity than the other two methods according to human evaluation. As indicated in Figure FIGREF25, the responses generated by VAE tend to repeat the responses related to some popular hate keyword. For example, “Use of the r-word is unacceptable in our discourse as it demeans and insults people with mental disabilities.” and “Please do not use derogatory language for intellectual disabilities.” are the generated responses for a large part of the Gab testing data. According to Figure FIGREF20, insults towards disabilities are the largest portion in the dataset, so we suspect that the performance of the VAE model is affected by the imbalanced keyword distribution.\nThe sampled results in Figure FIGREF25 show that the Seq2Seq and the RL model can generate reasonable responses for intervention. However, as is to be expected with machine-generated text, in the other human evaluation we conducted, where Mechanical Turk workers were also presented with sampled human-written responses alongside the machine generated responses, the human-written responses were chosen as the most effective and diverse option a majority of the time (70% or more) for both datasets. This indicates that there is significant room for improvement while generating automated intervention responses.\nIn our experiments, we only utilized the text of the posts, but more information is available and can be utilized, such as the user information and the title of a Reddit submission.\nOn both the Gab and Reddit datasets, the SVM classifier and the LR classifier achieved better performance than the CNN and RNN model with randomly initialized word embeddings.",

        "evidence": "First, to operationalize, we say that term $i$ is associated with gender $j$ if, when discussing individuals of gender $j$, $i$ is used with unusual frequency – which we can check with statistical hypothesis tests. Let $f_i$ represent the likelihood of $i$ appearing when discussing women or men. $f_i$ is unknown, but we can model the distribution of all possible $f_i$ using the corpus of texts that we have from the domain. We construct a gender-balanced version of the corpus by randomly undersampling the more prevalent gender until the proportions of each gender are equal. Assuming a non-informative prior distribution on $f_i$, the posterior distribution is Beta($k_i$, $N - k_i$), where $k_i$ is the count of $i$ in the gender-balanced corpus and $N$ is the total count of words in that corpus.\nAs BIBREF10 discuss, “the distribution of the gender-specific counts can be described by an integral over all possible $f_i$. This integral defines the Beta-Binomial distribution BIBREF29, and has a closed form solution.” We say that term $i$ is significantly associated with gender $j$ if the cumulative distribution at $k_{ij}$ (the count of $i$ in the $j$ portion of the gender-balanced corpus) is $p \\le 0.05$. As in the original work, we apply the Bonferroni correction BIBREF30 for multiple comparisons because we are computing statistical tests for thousands of hypotheses.\nFirst, we trained domain-specific word embeddings using the Word2Vec BIBREF33 CBOW model ($w \\in R^{100}$). Then, we used k-means clustering to cluster the embeddings of the gender-associated words. Since k-means may converge at local optima, we ran the algorithm 50 times and kept the model with the lowest sum of squared errors.\nTo automatically label the clusters, we combined the grounded knowledge of WordNet BIBREF34 and context-sensitive strengths of domain-specific word embeddings. Our algorithm is similar to BIBREF28's approach, but we extend their method by introducing domain-specific word embeddings for clustering as well as a new technique for sense disambiguation. Given a cluster, our algorithm proceeds with the following three steps:\nSense disambiguation: The goal is to assign each cluster word to one of its WordNet synsets; let $S$ represent the collection of chosen synsets. We know that these words have been clustered in domain-specific embedding space, which means that in the context of the domain, these words are very close semantically. Thus, we choose $S^*$ that minimizes the total distance between its synsets.\nCandidate label generation: In this step, we generate $L$, the set of possible cluster labels. Our approach is simple: we take the union of all hypernyms of the synsets in $S^*$.\nCandidate label ranking: Here, we rank the synsets in $L$. We want labels that are as close to all of the synsets in $S^*$ as possible; thus, we score the candidate labels by the sum of their distances to each synset in $S^*$ and we rank them from least to most distance.\nIn steps 1 and 3, we use WordNet pathwise distance, but we encourage the exploration of other distance representations as well.\nThen, we used kmeans clustering to cluster the embeddings of the gender-associated words.",

        "evidence": "We created a new dataset called CW-USPD-2016 (check-worthiness in the US presidential debates 2016) for finding check-worthy claims in context. In particular, we used four transcripts of the 2016 US election: one vice-presidential and three presidential debates. For each debate, we used the publicly-available manual analysis about it from nine reputable fact-checking sources, as shown in Table TABREF7. This could include not just a statement about factuality, but any free text that journalists decided to add, e.g., links to biographies or behavioral analysis of the opponents and moderators. We converted this to binary annotation about whether a particular sentence was annotated for factuality by a given source. Whenever one or more annotations were about part of a sentence, we selected the entire sentence, and when an annotation spanned over multiple sentences, we selected each of them.\nUltimately, we ended up with a dataset of four debates, with a total of 5,415 sentences. The agreement between the sources was low as Table TABREF8 shows: only one sentence was selected by all nine sources, 57 sentences by at least five, 197 by at least three, 388 by at least two, and 880 by at least one. The reason for this is that the different media aimed at annotating sentences according to their own editorial line, rather than trying to be exhaustive in any way. This suggests that the task of predicting which sentence would contain check-worthy claims will be challenging. Thus, below we focus on a ranking task rather than on absolute predictions. Moreover, we predict which sentence would be selected (i) by at least one of the media, or (ii) by a specific medium.\nNote that the investigative journalists did not select the check-worthy claims in isolation. Our analysis shows that these include claims that were highly disputed during the debate, that were relevant to the topic introduced by the moderator, etc. We will make use of these contextual dependencies below, which is something that was not previously tried in related work.\nWe created a new dataset called CW-USPD-2016 (check-worthiness in the US presidential debates 2016) for finding check-worthy claims in context.",

        "evidence": "In economics, a network effect (also called network externality or demand-side economies of scale) is the phenomenon by which the value or utility a user derives from a good or service depends on the number of users of compatible products. Network effects are typically positive, resulting in a given user deriving more value from a product as more users join the same network. The adoption of a product by an additional user can be broken into two effects: an increase in the value to all other users ( \"total effect\") and also the enhancement of other non-users' motivation for using the product (\"marginal effect\").\n\nNetwork effects can be direct or indirect. Direct network effects arise when a given user's utility increases with the number of other users of the same product or technology, meaning that adoption of a product by different users is complementary. This effect is separate from effects related to price, such as a benefit to existing users resulting from price decreases as more users join. Direct network effects can be seen with social networking services, including Twitter, Facebook, Airbnb, Uber, and LinkedIn; telecommunications devices like the telephone; and instant messaging services such as MSN, AIM or QQ. Indirect (or cross-group) network effects arise when there are \"at least two different customer groups that are interdependent, and the utility of at least one group grows as the other group(s) grow\". For example, hardware may become more valuable to consumers with the growth of compatible software.\n\nNetwork effects are commonly mistaken for economies of scale, which describe decreasing average production costs in relation to the total volume of units produced. Economies of scale are a common phenomenon in traditional industries such as manufacturing, whereas network effects are most prevalent in new economy industries, particularly information and communication technologies. Network effects are the demand side counterpart of economies of scale, as they function by increasing a customer's willingness to pay due rather than decreasing the supplier's average cost.\n\nUpon reaching critical mass, a bandwagon effect can result. As the network continues to become more valuable with each new adopter, more people are incentivized to adopt, resulting in a positive feedback loop. Multiple equilibria and a market monopoly are two key potential outcomes in markets that exhibit network effects. Consumer expectations are key in determining which outcomes will result.",

Moreover, if your Data and AI platform is made up of multiple services and components the administrative burden of governing and securing data and users and keeping all parts working together can be overwhelming especially at enterprise scale.\n\n3) MLOps: To make the most of AI you need to be able to use it to impact your business. Hiring a full data science team without having the right ML engineering expertise or the right tools to package, test, deploy and monitor is extremely wasteful. There are several steps that go into running effective end-to-end AI applications and your operating model should reflect that in the roles that are involved and in the way model lifecycle management is executed from use case identification, to development to deployment, and perhaps most importantly utilisation.  \n\nThese three dimensions should inform your focus and the roles that should be part of your development team.

        "question": "Which words are the most similar as per Twitter dataset for word fat?",
        "answer": "`female' and `woman'.",
        "evidence": "Cyberbullying has been defined by the National Crime Prevention Council as the use of the Internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person. Various studies have estimated that between to 10% to 40% of internet users are victims of cyberbullying BIBREF0 . Effects of cyberbullying can range from temporary anxiety to suicide BIBREF1 . Many high profile incidents have emphasized the prevalence of cyberbullying on social media. Most recently in October 2017, a Swedish model Arvida Byström was cyberbullied to the extent of receiving rape threats after she appeared in an advertisement with hairy legs.\nDetection of cyberbullying in social media is a challenging task. Definition of what constitutes cyberbullying is quite subjective. For example, frequent use of swear words might be considered as bullying by the general population. However, for teen oriented social media platforms such as Formspring, this does not necessarily mean bullying (Table TABREF9 ). Across multiple SMPs, cyberbullies attack victims on different topics such as race, religion, and gender. Depending on the topic of cyberbullying, vocabulary and perceived meaning of words vary significantly across SMPs. For example, in our experiments we found that for word `fat', the most similar words as per Twitter dataset are `female' and `woman' (Table TABREF23 ). However, other two datasets do not show such particular bias against women. This platform specific semantic similarity between words is a key aspect of cyberbullying detection across SMPs. Style of communication varies significantly across SMPs. For example, Twitter posts are short and lack anonymity. Whereas posts on Q&A oriented SMPs are long and have option of anonymity (Table TABREF7 ). Fast evolving words and hashtags in social media make it difficult to detect cyberbullying using swear word list based simple filtering approaches. The option of anonymity in certain social networks also makes it harder to identify cyberbullying as profile and history of the bully might not be available.\nPast works on cyberbullying detection have at least one of the following three bottlenecks. First (Bottleneck B1), they target only one particular social media platform. How these methods perform across other SMPs is unknown. Second (Bottleneck B2), they address only one topic of cyberbullying such as racism, and sexism. Depending on the topic, vocabulary and nature of cyberbullying changes. These models are not flexible in accommodating changes in the definition of cyberbullying. Third (Bottleneck B3), they rely on carefully handcrafted features such as swear word list and POS tagging. However, these handcrafted features are not robust against variations in writing style. In contrast to existing bottlenecks, this work targets three different types of social networks (Formspring: a Q&A forum, Twitter: microblogging, and Wikipedia: collaborative knowledge repository) for three topics of cyberbullying (personal attack, racism, and sexism) without doing any explicit feature engineering by developing deep learning based models along with transfer learning.\nWe experimented with diverse traditional machine learning models (logistic regression, support vector machine, random forest, naive Bayes) and deep neural network models (CNN, LSTM, BLSTM, BLSTM with Attention) using variety of representation methods for words (bag of character n-gram, bag of word unigram, GloVe embeddings, SSWE embeddings). Summary of our findings and research contributions is as follows.\nFor example, in our experiments we found that for word `fat', the most similar words as per Twitter dataset are `female' and `woman' (Table TABREF23 ).",

        "evidence": "Captain Oliver Cromwell Applegate (June 11, 1845 – October 11, 1938) was an American politician, newspaper editor, and Indian agent in the U.S. state of Oregon. A member of the Applegate family that helped open the Applegate Trail, he was raised in Southern Oregon where he later was in charge of the Klamath Indian Reservation. He worked as a scout during the Modoc War, was an Indian agent for all of Oregon, and was editor of the Ashland Tidings and the Klamath Republican.\n\nEarly years\nOliver Applegate was born in a log cabin in Yamhill District, in what is now Polk County, Oregon, on June 11, 1845. At the time the area was part of the Oregon Country, but in 1848 became part of the Oregon Territory. He was the sixth son and seventh child of the well-known pioneer, Lindsay Applegate, a native of Kentucky, and his wife, Elizabeth (Miller) Applegate, who was born in Tennessee in 1816. Lindsay Applegate was one of the leaders of the Great Migration of 1843 which Americanized Oregon and was prominent in the early Indian wars, and as an explorer.\n\nWhen Oliver Applegate was five years old, the family moved to the Yoncalla Valley in middle western Oregon; there were only three or four other families in that region at that time besides the Applegate contingent, which consisted of the brothers, Charles, Lindsay and Jesse, and their families.\n\nThe system of common schools was rudimentary then, and their continuity could not be depended upon for more than a few weeks or months in each year. The Applegate families were fairly well supplied with books, however, to supplement the otherwise meager opportunities for education, and as a rule the scions of these strong frontiersmen availed themselves of every opportunity offered to inform their minds, as well as to become accomplished horsemen, efficient in the use of the rifle and otherwise prepared for the border wars which were liable to occur at any time with the aboriginal inhabitants of the country.\n\nIn 1860 the family removed to the Siskiyou Mountains near the California boundary, Lindsay Applegate having become owner of the toll road over the mountains, and in 1862, removed to Ashland, Oregon, which continued to be the family home for many years.\n\nCareer\nDuring the winter of 1862, Oliver attended the district school in Ashland, and the next spring received a certificate and in the ensuing fall became the teacher, and for four successive winters, conducted the Ashland school. In the spring of 1863, he became a member of an independent military company, the only one in Southern Oregon, a cavalry company known as the \"Mountain Rangers,\" to which many of the leading citizens of the country belonged. He served as a private in this company the first year, the second year as a sergeant and in the third year was chosen captain, receiving his commissions before he had reached his twentieth year from Addison C. Gibbs, the old war governor of Oregon.\n\nIn 1865, his father was appointed United States Indian Agent over the Klamaths and Modocs at Fort Klamath. According to the treaty of 1864, the Indians were to be gathered on the Klamath Reservation. The fort was the only place east of the Cascades in that immediate region where there were any white people . The younger Applegate was appointed assistant to the agent, and that was the beginning of a service that lasted for several years, under various agency administrations, during which time he gained influence over the tribes of southeastern Oregon, which he used to good advantage later when the Modoc outbreak of 1872 occurred. This influence probably more than any other agency resulted finally in the conversion of the most resistant of the Indian tribes into farmers and stockmen.\n\nWhen 21 years of age, Applegate had charge of a unique company of scouts, called the \"Ax and Rifle Company,\" because every man carried an ax as well as a rifle. This company consisted of fifty men, the captain the only white man, while different chiefs of the various tribes ranked as lieutenants and sergeants. They cleared the way through the pine forests for a great wagon train of provisions and beef cattle that came down to the Klamath agency from The Dalles, marking the first step in the commencement of operations under the treaty of 1864 for the benefit of the southeastern tribes of Oregon. This was during the war with the Snake or Paiute Indians.\n\nFor some time before the Modoc outbreak of 1872, Applegate had charge of Yainax sub-agency, forty miles west of the headquarters' agency, then under supervision of Agent Laroy S. Dyar. Near Yainax was located the main band of the Modocs. under the famous old Chief Schonchin, and with him were to be domiciled the turbulent bands under the Modoc chieftain, Captain Jack. The story of how Captain Jack and his band refused to come onto the reservation, and the subsequent events, make up the history of the Modoc War. Applegate played a prominent part in the bloody drama.\n\nIn 1873, he became a U.S. Commissioner with jurisdiction committed against the federal law locally.\n\nIn 1876, some of Applegate's friends asked to have him appointed general Indian agent for Oregon, assuming that in such a way his unusual experience in the management of Indian affairs could be used to good purpose in promoting progressive conditions to the several agencies in the state. Ex-Senator Nesmith, who was himself a Democrat, was an ardent advocate of the plan and wrote as follows, to Hon. Zach Chandler, Grant's Secretary of the Interior, with whom he had served in the U.S. Senate: \"Mr. Applegate is a gentleman of culture and ability, and, unlike myself, he is a prominent Republican and is as honest as is possible for a man to be possessing his perverted political notions. You will pardon me, I know, for proposing appointments to an administration which I do not indorse, but I do so in order to promote the reforms which you have so happily inaugurated.\" In 1898, Applegate took charge of the Klamath Reservation as United States Indian agent, and served as such for five years. Congress then discontinued the position of agent and he was appointed bonded superintendent of the agency and training school, a position which he resigned after serving two years.\n\nDuring this period of seven years he helped establish Indian claims to over half a million dollars for lands excluded from the reservation by erroneous boundary surveys, and developed comprehensive plans for irrigation and drainage, which added to the wealth of the reservation, an area approximating in size the state of Delaware.\n\nHe was identified with various enterprises looking to the development of southern Oregon, and had a reputation as a writer of both prose and verse.\n\nLater years and family\nApplegate served as editor of the Ashland Tidings starting in 1878, and later edited the Klamath Republican.\n\nIn 1878, Applegate was married to Miss Ella Anderson, a daughter of Rev. Jesse Marion Anderson, a pioneer Methodist minister, who was widely known in southern Oregon as a man of ability and worth. The bride, like the groom, was a native of Oregon, having been born in the territory in 1855. They had three sons and three daughters. Frank Lindsay, the oldest, was born October 10, 1879; Annie Elizabeth, September 13, 1881; Laroy Gilbert, August 19, 1885; Rachel Emma, November 23, 1887; Jennie Margaret, April 5, 1894; and Oliver C., Jr., July 5, 1896. As of 1912, Applegate resided at Klamath Falls, Klamath County, Oregon. In politics, he was a Republican and a delegate to the Republican National Convention at Chicago in 1892. Oliver C. Applegate died on October 11, 1938, at the age of 93. He is the namesake of Applegate Peak in Crater Lake National Park.",

This led to the conversion of the most resistant Indian Tribes to farmers and stockmen.\n\nIn 1876, friends of Oliver Applegate wanted him to use his experience, from working with Indian affairs, to be appointed general Indian Agent for Oregon.

Labeling thousands of hours of audio, however, is expensive and time-consuming. A natural question to ask is how to achieve better generalization with fewer training examples. Active learning studies this problem by identifying and labeling only the most informative data, potentially reducing sample complexity. How much active learning can help in large-scale, end-to-end ASR systems, however, is still an open question.\nThe speech recognition community has generally identified the informativeness of samples by calculating confidence scores. In particular, an utterance is considered informative if the most likely prediction has small probability BIBREF1 , or if the predictions are distributed very uniformly over the labels BIBREF2 . Though confidence-based measures work well in practice, less attention has been focused on gradient-based methods like Expected Gradient Length (EGL) BIBREF3 , where the informativeness is measured by the norm of the gradient incurred by the instance. EGL has previously been justified as intuitively measuring the expected change in a model's parameters BIBREF3 .We formalize this intuition from the perspective of asymptotic variance reduction, and experimentally, we show EGL to be superior to confidence-based methods on speech recognition tasks. Additionally, we observe that the ranking of samples scored by EGL is not correlated with that of confidence scoring, suggesting EGL identifies aspects of an instance that confidence scores cannot capture.\nIn BIBREF3 , EGL was applied to active learning on sequence labeling tasks, but our work is the first we know of to apply EGL to speech recognition in particular. Gradient-based methods have also found applications outside active learning. For example, BIBREF4 suggests that in stochastic gradient descent, sampling training instances with probabilities proportional to their gradient lengths can speed up convergence. From the perspective of variance reduction, this importance sampling problem shares many similarities to problems found in active learning.\nwhere the informativeness is measured by the norm of the gradient incurred by the instance.",

        "question": "Using examples taken from the paragraph, provide the major risks to humans with climate change in a short bulleted list",
        "evidence": "The effects of climate change are impacting humans everywhere in the world. Impacts can now be observed on all continents and ocean regions, with low-latitude, less developed areas facing the greatest risk. Continued warming has potentially “severe, pervasive and irreversible impacts” for people and ecosystems. The risks are unevenly distributed, but are generally greater for disadvantaged people in developing and developed countries.\n\nThe WHO has classified climate change as the greatest threat to global health in the 21st century. Extreme weather leads to injury and loss of life, and crop failures to undernutrition. Various infectious diseases are more easily transmitted in a warmer climate, such as dengue fever and malaria. Young children are the most vulnerable to food shortages. Both children and older people are vulnerable to extreme heat. The World Health Organization (WHO) has estimated that between 2030 and 2050, climate change would cause around 250,000 additional deaths per year. They assessed deaths from heat exposure in elderly people, increases in diarrhea, malaria, dengue, coastal flooding, and childhood undernutrition. Over 500,000 more adult deaths are projected yearly by 2050 due to reductions in food availability and quality. By 2100, 50% to 75% of the global population may face climate conditions that are life-threatening due to combined effects of extreme heat and humidity.\n\nClimate change is affecting food security. It has caused reduction in global yields of maize, wheat, and soybeans between 1981 and 2010. Future warming could further reduce global yields of major crops. Crop production will probably be negatively affected in low-latitude countries, while effects at northern latitudes may be positive or negative. Up to an additional 183 million people worldwide, particularly those with lower incomes, are at risk of hunger as a consequence of these impacts. Climate change also impacts fish populations. Globally, less will be available to be fished. Regions dependent on glacier water, regions that are already dry, and small islands have a higher risk of water stress due to climate change.\n\nEconomic damages due to climate change may be severe and there is a chance of disastrous consequences. Climate change has likely already increased global economic inequality, and this trend is projected to continue. Most of the severe impacts are expected in sub-Saharan Africa, where most of the local inhabitants are dependent upon natural and agricultural resources and South-East Asia. The World Bank estimates that climate change could drive over 120 million people into poverty by 2030.\n\nCurrent inequalities based on wealth and social status have worsened due to climate change. Major difficulties in mitigating, adapting, and recovering to climate shocks are faced by marginalized people who have less control over resources. Indigenous people, who are subsistent on their land and ecosystems, will face endangerment to their wellness and lifestyles due to climate change. An expert elicitation concluded that the role of climate change in armed conflict has been small compared to factors such as socio-economic inequality and state capabilities.\n\nLow-lying islands and coastal communities are threatened by sea level rise, which makes flooding more common. Sometimes, land is permanently lost to the sea. This could lead to statelessness for people in island nations, such as the Maldives and Tuvalu. In some regions, the rise in temperature and humidity may be too severe for humans to adapt to. With worst-case climate change, models project that almost one-third of humanity might live in extremely hot and uninhabitable climates, similar to the current climate found in the Sahara. These factors can drive environmental migration, both within and between countries. More people are expected to be displaced because of sea level rise, extreme weather and conflict from increased competition over natural resources. Climate change may also increase vulnerability, leading to \"trapped populations\" who are not able to move due to a lack of resources.",

Informally: if we set the variables in X to x, then Y takes on the values y, regardless of the values of all other variables. In the context of causal models I have coined this direct sufficiency.\nObviously the second form of sufficient explanations is stronger. Coming back to our example, X 2 = 45, 001 is a sufficient explanation for Y = 1 according to both readings. But (X 1 = 50, 000, X 3 = 25, 000) is a sufficient explanation of Y = 1 only on the first reading, for although it is weakly sufficient for Y = 1 it is not directly sufficient. Which one of these notions is correct here? Imagine that a prospective applicant with these values is told that their income and initial deposit suffice for getting a loan. As a result the applicant concludes that there is no need to have such high savings and decides to spend 20, 000, so that their loan application is denied. The applicant would be quite right to be upset about this! Such misunderstandings cannot occur when using direct sufficiency, as that gives us settings whose explanatory value is immune to the influence of interventions on other variables. Instead of concluding from this that one should always rely on direct sufficiency, I propose a generalization of sufficient explanations that adds an element to inform us explicitly as to which variables are assumed to be safeguarded from interventions. Concretely, in addition to specifying which variables need to be set to particular values, a sufficient explanation should also specify a set of variables N that are not to be manipulated for the explanation to be action-guiding. Informally, if we set the variables in X to x and the variables in N are safeguarded from interventions, then Y takes on the value y, regardless of the values of all remaining variables. I call the relevant notion of causal sufficiency at work strong sufficiency, which can be formally defined as follows:\nNote that in this definition N cannot just be any set, but rather we require that it is itself entirely determined by X = x. This is because the variables in N can be thought of as a network that transmits the causal influence of X to Y , and the idea of safeguarding this network is that it can continue fulfilling this role even when intervening on X. (I refer the reader to for an elaborate discussion of this definition as well as an equivalent alternative formulation.)\nThe following straightforward result shows the relative strengths of the above three notions of sufficiency.\nProposition 8 If X = x is directly sufficient for Y = y then X = x is strongly sufficient for Y = y along some N , and if X = x is strongly sufficient for Y = y along some N then X = x is weakly sufficient for Y = y.\nUsing strong sufficiency we can define a sufficient explanation so that it specifies all the required elements for it to be action-guiding.\nIf N = Y we speak of a direct sufficient explanation.\nOf course we do not want to add redundant parts to a sufficient set, as a good explanation should be as concise as possible. Therefore a good sufficient explanation ought to be minimal with respect both to X and to N .\nThis allows us to define what makes for a good sufficient explanation of an observed output.\nDefinition 11 An actual sufficient explanation (X 1 = x 1 , N 1 ) of Y = y in (M, u) is good if it is not dominated by any other actual sufficient explanation in (M, u).\nTo conclude the analysis of sufficient explanations, I offer a first result that shows the extreme limitation Independence poses. We have seen three very different notions of sufficiency, and yet under Independence they all collapse into one.\nTheorem 12 If a causal model M that agrees with h satisfies Independence then the following statements are all equivalent:\n(Proofs of all Theorems are to be found in the Supplementary Material.)\nDefinition 6 X = x is directly sufficient for Y = y in M if for all c ∈ R(C), where C = V − (X ∪ Y ), and all u ∈ R(U) we have that (M,u) |= [X ← x, C ← c]Y = y.",

Adams was a dedicated diarist and regularly corresponded with many important contemporaries, including his wife and adviser Abigail Adams as well as his friend and rival Thomas Jefferson.\n\nA lawyer and political activist prior to the Revolution, Adams was devoted to the right to counsel and presumption of innocence. He defied anti-British sentiment and successfully defended British soldiers against murder charges arising from the Boston Massacre. Adams was a Massachusetts delegate to the Continental Congress and became a leader of the revolution. He assisted Jefferson in drafting the Declaration of Independence in 1776. As a diplomat in Europe, he helped negotiate a peace treaty with Great Britain and secured vital governmental loans. Adams was the primary author of the Massachusetts Constitution in 1780, which influenced the United States constitution, as did his essay Thoughts on Government.\n\nAdams was elected to two terms as vice president under President George Washington and was elected as the United States' second president in 1796. He was the only president elected under the banner of the Federalist Party. During his single term, Adams encountered fierce criticism from the Jeffersonian Republicans and from some in his own Federalist Party, led by his rival Alexander Hamilton. Adams signed the controversial Alien and Sedition Acts, and built up the Army and Navy in the undeclared naval war (called the \"Quasi-War\") with France. During his term, he became the first president to reside in the executive mansion now known as the White House.\n\nIn his bid in 1800 for reelection to the presidency, opposition from Federalists and accusations of despotism from Jeffersonians led to Adams losing to his vice president and former friend Jefferson, and he retired to Massachusetts. He eventually resumed his friendship with Jefferson by initiating a correspondence that lasted fourteen years. He and his wife generated the Adams political family, a line of politicians, diplomats, and historians. It includes their son John Quincy Adams, the sixth president. John Adams died on July 4, 1826 – the fiftieth anniversary of the adoption of the Declaration of Independence – hours after Jefferson's death. Adams and his son are the only presidents of the first twelve who never owned slaves. Surveys of historians and scholars have favorably ranked his administration.",

        "answer": "It is among the best performing models on SQuAD and TriviaQA",
        "evidence": "Our system comprises of following three steps:\nCloze generation: Most of the documents typically follow a template, they begin with an introduction that provides an overview and a brief summary for what is to follow. We assume such a structure while constructing our cloze style questions. When there is no clear demarcation, we treat the first $K\\%$ (hyperparameter, in our case 20%) of the document as the introduction. While noisy, this heuristic generates a large number of clozes given any corpus, which we found to be beneficial for semi-supervised learning despite the noise.\nWe use a standard NLP pipeline based on Stanford CoreNLP (for SQuAD, TrivaQA and PubMed) and the BANNER Named Entity Recognizer (only for PubMed articles) to identify entities and phrases. Assume that a document comprises of introduction sentences $\\lbrace q_1, q_2, ... q_n\\rbrace $ , and the remaining passages $\\lbrace p_1, p_2, .. p_m\\rbrace $ . Additionally, let's say that each sentence $q_i$ in introduction is composed of words $\\lbrace w_1, w_2, ... w_{l_{q_i}}\\rbrace $ , where $l_{q_i}$ is the length of $q_i$ . We consider a $\\text{match} (q_i, p_j)$ , if there is an exact string match of a sequence of words $\\lbrace w_k, w_{k+1}, .. w_{l_{q_i}}\\rbrace $ between the sentence $q_i$ and passage $p_j$ . If this sequence is either a noun phrase, verb phrase, adjective phrase or a named entity in $\\lbrace p_1, p_2, .. p_m\\rbrace $0 , as recognized by CoreNLP or BANNER, we select it as an answer span $\\lbrace p_1, p_2, .. p_m\\rbrace $1 . Additionally, we use $\\lbrace p_1, p_2, .. p_m\\rbrace $2 as the passage $\\lbrace p_1, p_2, .. p_m\\rbrace $3 and form a cloze question $\\lbrace p_1, p_2, .. p_m\\rbrace $4 from the answer bearing sentence $\\lbrace p_1, p_2, .. p_m\\rbrace $5 by replacing $\\lbrace p_1, p_2, .. p_m\\rbrace $6 with a placeholder. As a result, we obtain passage-question-answer ( $\\lbrace p_1, p_2, .. p_m\\rbrace $7 ) triples (Table 1 shows an example). As a post-processing step, we prune out $\\lbrace p_1, p_2, .. p_m\\rbrace $8 triples where the word overlap between the question (Q) and passage (P) is less than 2 words (after excluding the stop words).\nThe process relies on the fact that answer candidates from the introduction are likely to be discussed in detail in the remainder of the article. In effect, the cloze question from the introduction and the matching paragraph in the body forms a question and context passage pair. We create two cloze datasets, one each from Wikipedia corpus (for SQuAD and TriviaQA) and PUBMed academic papers (for the BioASQ challenge), consisting of 2.2M and 1M clozes respectively. From analyzing the cloze data manually, we were able to answer 76% times for the Wikipedia set and 80% times for the PUBMed set using the information in the passage. In most cases the cloze paraphrased the information in the passage, which we hypothesized to be a useful signal for the downstream QA task.\nWe also investigate the utility of forming subsets of the large cloze corpus, where we select the top passage-question-answer triples, based on the different criteria, like i) jaccard similarity of answer bearing sentence in introduction and the passage ii) the tf-idf scores of answer candidates and iii) the length of answer candidates. However, we empirically find that we were better off using the entire set rather than these subsets.\nPre-training: We make use of the generated cloze dataset to pre-train an expressive neural network designed for the task of reading comprehension. We work with two publicly available neural network models – the GA Reader BIBREF2 (to enable comparison with prior work) and BiDAF + Self-Attention (SA) model from BIBREF1 (which is among the best performing models on SQuAD and TriviaQA). After pretraining, the performance of BiDAF+SA on a dev set of the (Wikipedia) cloze questions is 0.58 F1 score and 0.55 Exact Match (EM) score. This implies that the cloze corpus is neither too easy, nor too difficult to answer.\nFine Tuning: We fine tune the pre-trained model, from the previous step, over a small set of labelled question-answer pairs. As we shall later see, this step is crucial, and it only requires a handful of labelled questions to achieve a significant proportion of the performance typically attained by training on tens of thousands of questions.\nPre-training: We make use of the generated cloze dataset to pre-train an expressive neural network designed for the task of reading comprehension.

        "question": "Given these paragraphs about Large language models, when was the first model in OpenAI's GPT series trained?",
        "evidence": "A large language model (LLM) is a language model consisting of a neural network with many parameters (typically billions of weights or more), trained on large quantities of unlabelled text using self-supervised learning. LLMs emerged around 2018 and perform well at a wide variety of tasks. This has shifted the focus of natural language processing research away from the previous paradigm of training specialized supervised models for specific tasks.\n\nProperties\nThough the term large language model has no formal definition, it often refers to deep learning models having a parameter count on the order of billions or more. LLMs are general purpose models which excel at a wide range of tasks, as opposed to being trained for one specific task (such as sentiment analysis, named entity recognition, or mathematical reasoning). The skill with which they accomplish tasks, and the range of tasks at which they are capable, seems to be a function of the amount of resources (data, parameter-size, computing power) devoted to them, in a way that is not dependent on additional breakthroughs in design.\n\nThough trained on simple tasks along the lines of predicting the next word in a sentence, neural language models with sufficient training and parameter counts are found to capture much of the syntax and semantics of human language. In addition, large language models demonstrate considerable general knowledge about the world, and are able to \"memorize\" a great quantity of facts during training.\n\nHallucinations\nMain article: Hallucination (artificial intelligence)\nIn artificial intelligence in general, and in large language models in particular, a \"hallucination\" is a confident response that does not seem to be justified by the model's training data.\n\nEmergent abilities\n\nOn a number of natural language benchmarks involving tasks such as question answering, models perform no better than random chance until they reach a certain scale (in this case, measured by training computation), at which point their performance sharply increases. These are examples of emergent abilities.\nUnpredictable abilities that have been observed in large language models but that were not present in simpler models (and that were not explicitly designed into the model) are usually called \"emergent abilities\". Researchers note that such abilities \"cannot be predicted simply by extrapolating the performance of smaller models\". These abilities are discovered rather than programmed-in or designed, in some cases only after the LLM has been publicly deployed. Hundreds of emergent abilities have been described. Examples include multi-step arithmetic, taking college-level exams, identifying the intended meaning of a word, chain-of-thought prompting, decoding the International Phonetic Alphabet, unscrambling a word’s letters, identifying offensive content in paragraphs of Hinglish (a combination of Hindi and English), and generating a similar English equivalent of Kiswahili proverbs.\n\nArchitecture and training\nLarge language models have most commonly used the transformer architecture, which, since 2018, has become the standard deep learning technique for sequential data (previously, recurrent architectures such as the LSTM were most common). LLMs are trained in an unsupervised manner on unannotated text. A left-to-right transformer is trained to maximize the probability assigned to the next word in the training data, given the previous context. Alternatively, an LLM may use a bidirectional transformer (as in the example of BERT), which assigns a probability distribution over words given access to both preceding and following context. In addition to the task of predicting the next word or \"filling in the blanks\", LLMs may be trained on auxiliary tasks which test their understanding of the data distribution such as Next Sentence Prediction (NSP), in which pairs of sentences are presented and the model must predict whether they appear side-by-side in the training corpus.\n\nThe earliest LLMs were trained on corpora having on the order of billions of words. The first model in OpenAI's GPT series was trained in 2018 on BookCorpus, consisting of 985 million words. In the same year, BERT was trained on a combination of BookCorpus and English Wikipedia, totalling 3.3 billion words. In the years since then, training corpora for LLMs have increased by orders of magnitude, reaching up to hundreds of billions or trillions of tokens.\n\nLLMs are computationally expensive to train. A 2020 study estimated the cost of training a 1.5 billion parameter model (1-2 orders of magnitude smaller than the state of the art at the time) at $1.6 million.\n\nA 2020 analysis found that neural language models' capability (as measured by training loss) increased smoothly in a power law relationship with number of parameters, quantity of training data, and computation used for training. These relationships were tested over a wide range of values (up to seven orders of magnitude) and no attenuation of the relationship was observed at the highest end of the range (including for network sizes up to trillions of parameters).\n\nApplication to downstream tasks\nBetween 2018 and 2020, the standard method for harnessing an LLM for a specific natural language processing (NLP) task was to fine tune the model with additional task-specific training. It has subsequently been found that more powerful LLMs such as GPT-3 can solve tasks without additional training via \"prompting\" techniques, in which the problem to be solved is presented to the model as a text prompt, possibly with some textual examples of similar problems and their solutions.\n\nFine-tuning\nMain article: Fine-tuning (machine learning)\nFine-tuning is the practice of modifying an existing pretrained language model by training it (in a supervised fashion) on a specific task (e.g. sentiment analysis, named entity recognition, or part-of-speech tagging). It is a form of transfer learning. It generally involves the introduction of a new set of weights connecting the final layer of the language model to the output of the downstream task. The original weights of the language model may be \"frozen\", such that only the new layer of weights connecting them to the output are learned during training. Alternatively, the original weights may receive small updates (possibly with earlier layers frozen).\n\nPrompting\nSee also: Prompt engineering and Few-shot learning (natural language processing)\nIn the prompting paradigm, popularized by GPT-3, the problem to be solved is formulated via a text prompt, which the model must solve by providing a completion (via inference). In \"few-shot prompting\", the prompt includes a small number of examples of similar (problem, solution) pairs. For example, a sentiment analysis task of labelling the sentiment of a movie review could be prompted as follows:\n\nReview: This movie stinks.\nSentiment: negative\n\nReview: This movie is fantastic!\nSentiment:\n\nIf the model outputs \"positive\", then it has correctly solved the task. In zero-shot prompting, no solve examples are provided. An example of a zero-shot prompt for the same sentiment analysis task would be \"The sentiment associated with the movie review 'This movie is fantastic!' is\".\n\nFew-shot performance of LLMs has been shown to achieve competitive results on NLP tasks, sometimes surpassing prior state-of-the-art fine-tuning approaches. Examples of such NLP tasks are translation, question answering, cloze tasks, unscrambling words, and using a novel word in a sentence. The creation and optimisation of such prompts is called prompt engineering.\n\nInstruction tuning\nInstruction tuning is a form of fine-tuning designed to facilitate more natural and accurate zero-shot prompting interactions. Given a text input, a pretrained language model will generate a completion which matches the distribution of text on which it was trained. A naive language model given the prompt \"Write an essay about the main themes of Hamlet.\" might provide a completion such as \"A late penalty of 10% per day will be applied to submissions received after March 17.\" In instruction tuning, the language model is trained on many examples of tasks formulated as natural language instructions, along with appropriate responses. Various techniques for instruction tuning have been applied in practice. OpenAI's InstructGPT protocol involves supervised fine-tuning on a dataset of human-generated (prompt, response) pairs, followed by reinforcement learning from human feedback (RLHF), in which a reward function was learned based on a dataset of human preferences. Another technique, \"self-instruct\", fine-tunes the language model on a training set of examples which are themselves generated by an LLM (bootstrapped from a small initial set of human-generated examples).\n\nhttps://en.wikipedia.org/wiki/Large_language_model",

Unhappy with the level of pay, Smith auditioned for numerous dancing roles, while facing racial prejudice. \"When that happens, you realize that you have to be even better or move to L.A. where it doesn't matter,\" he said later.\n\nNoticed by singer Michael Jackson, Smith landed a job as a dancer before becoming his choreographer. Smith worked on three of Jackson's world tours; Bad, Dangerous and HIStory. He also worked as a choreographer in Michael Jackson's Ghosts, and for the musical Thriller - Live.\n\nSmith appeared on the concert tours of The Rolling Stones, Diana Ross and Janet Jackson's Rhythm Nation 1814 Tour. Smith also worked for Victoria Beckham after the Spice Girl made a return as a solo artist.\n\nSmith was awarded four MTV Video awards for co-choreographing En Vogue's music videos \"My Lovin'\" (1992), \"Free Your Mind\" (1993), \"Whatta Man\" (1994) and Michael Jackson's duet with sister Janet, \"Scream\" (1995). The music video for Beyoncé's \"Crazy in Love\" won Smith his fifth MTV Video Music Award for Best Choreography in 2003.\n\nHis other awards include a SSDC Bob Fosse award and an Emmy award. Smith was also the youngest inductee into the Millers Gallery of Greats.\n\nSmith has choreographed Invincible: A Glorious Tribute To Michael Jackson featuring Jeffrey Perez and Pete Carter.\n\nSmith's work with Michael Jackson is the subject of the 2019 documentary film The Man Behind The Dance.",

With improvements in cruise control technology and other driver assistance functions like lane keep assist, cars are taking over more of the driving process than ever before. While the intent is to make it safer for drivers, it also has the unintended consequence of making easier for drivers to be distracted. \n\nCars with manual transmissions not only force greater engagement and focus, but they are also either incompatible with, or only compatible with lesser versions of, certain driver assistance features like adaptive cruise control because lowering the speed while not being able to change the gear (which is manual) could cause the car to stall. \n\nParadoxically, by increasing the required inputs and decreasing the number of driver assistance features, driving a manual transmission car is safest.",

These models have achieved blackstate-of-the-art results in various language generation tasks, including abstractive summarization.\nHowever, when generating a summary, it is essential to correctly predict which part of the source text should be included in the summary. Some previous studies without pre-training have examined combining extractive summarization with abstractive summarization BIBREF3, BIBREF4.

        "answer": "1. Make sure both batteries have the same voltage (they probably do unless one car is old). Don’t jump start a frozen battery (it may explode), or a battery with cracks in the casing\nKeep metal objects away from the battery. If they cause a spark it could be dangerous.\n\n2. Park the two cars facing each other, close but with enough space to walk in between.\n\n3. Remove the keys from the ignitions, turn off lights/blinkers.\n\n4. Disconnect all accessories (voltage spikes can damage them).\n\n5. Clamp one of the red (positive) clamp to the positive terminal of the dead battery. If there is corrosion on the terminal, clean off or scrape the residue, and/or twist the jaws of the clamp until it cuts through the corrosion and into the metal. Make sure the black clamp of the same end isn’t touching any metal.\n\n6. Connect the other red clamp to the positive terminal of the good battery.\n\n7. Connect the black (negative) clamp to the negative terminal of the good battery.\n\n8. Attach the other black clamp to an unpainted metal surface (e.g. bolt, bracket) on the engine of the car with the dead battery, at least a few inches away from the battery. If a labeled remote negative terminal is available, use it.\n\n9. Confirm that the jumper cables are not near any moving engine parts.\n\n10. Start the booster car, and let it idle for 5 minutes to build up a charge in the dead battery. This will take longer if the dead battery is really empty.\n\n11. Start the car with the dead battery and let the two vehicles idle for a few minutes. If the car doesn’t start, wait a few more minutes and try again. In some instances, slightly revving the engine of the running car while charging the dead battery may help. If it still doesn’t start, it probably won’t.\n\n12. Disconnect the jumper cables reversing the connection order, making sure no disconnected clamps touch any metal or each other\n\n13. Drive the jump-started car for at least 20-30 minutes so it can recharge the battery\nTry to keep the jumper cables with you; you may need to jump again the next time you start the car.",

        "evidence": "The methods that we evaluated are baselines are the ones we consider to be basic and with moderate potential of yielding particularly good results. Probably the most straightforward approach to error correction is selecting known words from a dictionary that are within the smallest edit distance from the error. We used the Levenshtein distance metric BIBREF8 implemented in Apache Lucene library BIBREF9 . It is a version of edit distance that treats deletions, insertions and replacements as adding one unit distance, without giving a special treatment to character swaps. The SGJP – Grammatical Dictionary of Polish BIBREF10 was used as the reference vocabulary.\nAnother simple approach is the aforementioned diacritical swapping, which is a term that we introduce here for referring to a solution inspired by the work of BIBREF4 . Namely, from the incorrect form we try to produce all strings obtainable by either adding or removing diacritical marks from characters. We then exclude options that are not present in SGJP, and select as the correction the one within the smallest edit distance from the error. It is possible for the number of such diacritically-swapped options to become very big. For example, the token Modlin-Zegrze-Pultusk-Różan-Ostrołęka-Łomża-Osowiec (taken from PlEWi corpus of spelling errors, see below) can yield over INLINEFORM0 states with this method, such as Módłiń-Żęgrzę-Pułtuśk-Roźąń-Óśtróleką-Lómzą-Óśówięć. The actual correction here is just fixing the ł in Pułtusk. Hence we only try to correct in this way tokens that are shorter than 17 characters.\nA promising method, adapted from work on correcting texts by English language learners BIBREF11 , expands on the concept of selecting a correction nearest to the spelling error according to some notion of distance. Here, the Levenshtein distance is used in a weighted sum to cosine distance between word vectors. This is based on the observation that trained vectors models of distributional semantics contain also representations of spelling errors, if they were not pruned. Their representations tend to be similar to those of their correct counterparts. For example, the token enginir will appear in similar contexts as engineer, and therefore will be assigned a similar vector embedding.\n(applied cellwise) in order to obtain the initial setting of parameters for the main LSTM.

        "evidence": "Today there are 28 public libraries in Edinburgh but, as the first to open in the Scottish capital, the creation of Central Library was funded with £50,000 by philanthropist Andrew Carnegie. At the opening ceremony a telegram from Carnegie was read out stating: \"We trust that this Library is to grow in usefulness year after year, and prove one of the most potent agencies for the good of the people for all time to come.\"\n\nThe site selected for the library was the former home of Sir Thomas Hope, 1st Baronet Hope of Craighall, advocate for King Charles I. The structure, built in 1616, was demolished in March 1887 to make way for the library. The lintel from Hope's home, bearing the carved inscription TECUM HABITA 1616 from the fourth satire of Persius, is preserved above an inner doorway of the library.\n\nCarnegie's funding was initially an offer of £25,000 in 1886 which was doubled, overcoming prior opposition to the establishment of a public library, the city—last of those to do so in Scotland—adopted the Public Libraries Act and on 9 July 1887, Carnegie laid the foundation stone of architect George Washington Browne's French Renaissance-styled building.\n\nWashington Browne's design was the winning entry in the architectural competition for the new library and was selected from 37 submissions. His grand building stands three levels tall above George IV Bridge and reaches down to the Cowgate below, spanning the disjointed streets of Edinburgh's Old Town.\n\nAbove the main door is the motto, \"Let there be Light\" which Carnegie insisted was placed above the entrance to every library he funded. The facade of Central Library is also decorated with stone carvings depicting the coat of arms of the City of Edinburgh, Coat of Arms of Scotland and the Royal Arms. There are nine small square reliefs relating to printers and a large sculpture of Caledonia by Alexander Handyside Ritchie.\n\nRecords for 1890, the first full year the library was open, show that over 440,000 book loans were issued.\n\nCentral library has been adapted and expanded many times over the years. Only a year after opening the library was already running out of space and a book store was added in 1903. By 1928, the library was short of space again. Proposals were made for a better use of the space and a public lift was installed.\n\nIn 1930, the adjacent building at no.3 George IV Bridge was acquired allowing the library to expand again. Further nearby premises were bought in the 1940s and in 1961, a mezzanine level was created above the former Newspaper Room.\n\nIn May 2014, the new children's and music libraries were opened within the main library building. These had previously been housed in a separate building on George IV Bridge. The children's library features a wall graphic by award-winning children's book illustrator Catherine Rayner.\n\nIn November 2017, on the 100th anniversary of her death, a memorial to Dr Elsie Inglis, the founder of the Scottish Women's Hospitals, was unveiled at Central Library.",

        "answer": "The authors have built a dialogue summarization model that first converts a conversation into a structured text document and later applies an attention-based pointer network to create an abstractive summary.",
        "evidence": "The goal of the summarization task is condensing a piece of text into a shorter version that covers the main points succinctly. In the abstractive approach important pieces of information are presented using words and phrases not necessarily appearing in the source text. This requires natural language generation techniques with high level of semantic understanding BIBREF0, BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6.\nMajor research efforts have focused so far on summarization of single-speaker documents like news (e.g., BIBREF7) or scientific publications (e.g., BIBREF8). One of the reasons is the availability of large, high-quality news datasets with annotated summaries, e.g., CNN/Daily Mail BIBREF9, BIBREF7. Such a comprehensive dataset for dialogues is lacking.\nThe challenges posed by the abstractive dialogue summarization task have been discussed in the literature with regard to AMI meeting corpus BIBREF10, e.g. BIBREF11, BIBREF12, BIBREF13. Since the corpus has a low number of summaries (for 141 dialogues), BIBREF13 proposed to use assigned topic descriptions as gold references. These are short, label-like goals of the meeting, e.g., costing evaluation of project process; components, materials and energy sources; chitchat. Such descriptions, however, are very general, lacking the messenger-like structure and any information about the speakers.\nTo benefit from large news corpora, BIBREF14 built a dialogue summarization model that first converts a conversation into a structured text document and later applies an attention-based pointer network to create an abstractive summary. Their model, trained on structured text documents of CNN/Daily Mail dataset, was evaluated on the Argumentative Dialogue Summary Corpus BIBREF15, which, however, contains only 45 dialogues.\nIn the present paper, we further investigate the problem of abstractive dialogue summarization. With the growing popularity of online conversations via applications like Messenger, WhatsApp and WeChat, summarization of chats between a few participants is a new interesting direction of summarization research. For this purpose we have created the SAMSum Corpus which contains over 16k chat dialogues with manually annotated summaries. The dataset is freely available for the research community.\nThe paper is structured as follows: in Section SECREF2 we present details about the new corpus and describe how it was created, validated and cleaned. Brief description of baselines used in the summarization task can be found in Section SECREF3. In Section SECREF4, we describe our experimental setup and parameters of models. Both evaluations of summarization models, the automatic with ROUGE metric and the linguistic one, are reported in Section SECREF5 and Section SECREF6, respectively. Examples of models' outputs and some errors they make are described in Section SECREF7. Finally, discussion, conclusions and ideas for further research are presented in sections SECREF8 and SECREF9.\nTo benefit from large news corpora, built a dialogue summarization model that first converts a conversation into a structured text document and later applies an attention-based pointer network to create an abstractive summary.",

        "evidence": "Geometric bias mitigation uses the cosine distances between words to both measure and remove gender bias BIBREF0. This method implicitly defines bias as a geometric asymmetry between words when projected onto a subspace, such as the gender subspace constructed from a set of gender pairs such as $\\mathcal {P} = \\lbrace (he,she),(man,woman),(king,queen)...\\rbrace $. The projection of a vector $v$ onto $B$ (the subspace) is defined by $v_B = \\sum _{j=1}^{k} (v \\cdot b_j) b_j$ where a subspace $B$ is defined by k orthogonal unit vectors $B = {b_1,...,b_k}$.\nThe WEAT statistic BIBREF1 demonstrates the presence of biases in word embeddings with an effect size defined as the mean test statistic across the two word sets:\nWhere $s$, the test statistic, is defined as: $s(w,A,B) = mean_{a \\in A} cos(w,a) - mean_{b \\in B} cos(w,a)$, and $X$,$Y$,$A$, and $B$ are groups of words for which the association is measured. Possible values range from $-2$ to 2 depending on the association of the words groups, and a value of zero indicates $X$ and $Y$ are equally associated with $A$ and $B$. See BIBREF4 for further details on WEAT.\nThe RIPA (relational inner product association) metric was developed as an alternative to WEAT, with the critique that WEAT is likely to overestimate the bias of a target attribute BIBREF4. The RIPA metric formalizes the measure of bias used in geometric bias mitigation as the inner product association of a word vector $v$ with respect to a relation vector $b$. The relation vector is constructed from the first principal component of the differences between gender word pairs. We report the absolute value of the RIPA metric as the value can be positive or negative according to the direction of the bias. A value of zero indicates a lack of bias, and the value is bound by $[-||w||,||w||]$.\nThe neighborhood bias metric proposed by BIBREF5 quantifies bias as the proportion of male socially-biased words among the $k$ nearest socially-biased male and female neighboring words, whereby biased words are obtained by projecting neutral words onto a gender relation vector. As we only examine the target word among the 1000 most socially-biased words in the vocabulary (500 male and 500 female), a word’s bias is measured as the ratio of its neighborhood of socially-biased male and socially-biased female words, so that a value of 0.5 in this metric would indicate a perfectly unbiased word, and values closer to 0 and 1 indicate stronger bias.\nFLOAT SELECTED: Table 1: Remaining Bias (as measured by RIPA and Neighborhood metrics) in fastText embeddings for baseline (top two rows) and our (bottom three) methods.

        "evidence": "LeBron Raymone James Sr. (/ləˈbrɒn/; born December 30, 1984) is an American professional basketball player for the Los Angeles Lakers in the National Basketball Association (NBA). Nicknamed \"King James\", he is considered to be one of the greatest basketball players in history and is often compared to Michael Jordan in debates over the greatest basketball player of all time. James is the all-time leading scorer in NBA history and ranks fourth in career assists. He has won four NBA championships (two with the Miami Heat, one each with the Lakers and Cleveland Cavaliers), and has competed in 10 NBA Finals. He has four MVP awards, four Finals MVP awards, and two Olympic gold medals. He has been named an All-Star 19 times, selected to the All-NBA Team 18 times (including 13 First Team selections) and the All-Defensive Team six times, and was a runner-up for the NBA Defensive Player of the Year Award twice in his career.\n\nJames grew up playing basketball for St. Vincent–St. Mary High School in his hometown of Akron, Ohio. He was heavily touted by the national media as a future NBA superstar. A prep-to-pro, he was selected by the Cleveland Cavaliers with the first overall pick of the 2003 NBA draft. Named the 2004 NBA Rookie of the Year, he soon established himself as one of the league's premier players, leading the Cavaliers to their first NBA Finals appearance in 2007 and winning the NBA MVP award in 2009 and 2010. After failing to win a championship with Cleveland, James left in 2010 as a free agent to join the Miami Heat; this was announced in a nationally televised special titled The Decision and is among the most controversial free agency moves in sports history.\n\nJames won his first two NBA championships while playing for the Heat in 2012 and 2013; in both of these years, he also earned the league's MVP and Finals MVP awards. After his fourth season with the Heat in 2014, James opted out of his contract and re-signed with the Cavaliers. In 2016, he led the Cavaliers to victory over the Golden State Warriors in the Finals by coming back from a 3–1 deficit, delivering the team's first championship and ending the Cleveland sports curse. In 2018, James exercised his contract option to leave the Cavaliers and signed with the Lakers, where he won the 2020 NBA championship and his fourth Finals MVP. James is the first player in NBA history to accumulate $1 billion in earnings as an active player. On February 7, 2023, James surpassed Kareem Abdul-Jabbar to become the all-time leading scorer in NBA history.\n\nOff the court, James has accumulated more wealth and fame from numerous endorsement contracts. He has been featured in books, documentaries (including winning two Sports Emmy Awards as an executive producer), and television commercials. He has won 19 ESPY Awards, hosted Saturday Night Live, and starred in the sports film Space Jam: A New Legacy (2021). James has been a part-owner of Liverpool F.C. since 2011 and leads the LeBron James Family Foundation, which has opened an elementary school, housing complex, retail plaza, and medical center in Akron.",

        "evidence": "Question answering (QA) has been a blooming research field for the last decade. Selection-based QA implies a family of tasks that find answer contexts from large data given questions in natural language. Three tasks have been proposed for selection-based QA. Given a document, answer extraction BIBREF0 , BIBREF1 finds answer phrases whereas answer selection BIBREF2 , BIBREF3 , BIBREF4 , BIBREF5 and answer triggering BIBREF6 , BIBREF7 find answer sentences instead, although the presence of the answer context is not assumed within the provided document for answer triggering but it is for the other two tasks. Recently, various QA tasks that are not selection-based have been proposed BIBREF8 , BIBREF9 , BIBREF10 , BIBREF11 ; however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT Start).\nSeveral datasets have been released for selection-based QA. wang:07a created the QASent dataset consisting of 277 questions, which has been widely used for benchmarking the answer selection task. feng:15a presented InsuranceQA comprising 16K+ questions on insurance contexts. yang:15a introduced WikiQA for answer selection and triggering. jurczyk:16 created SelQA for large real-scale answer triggering. rajpurkar2016squad presented SQuAD for answer extraction and selection as well as for reading comprehension. Finally, morales-EtAl:2016:EMNLP2016 provided InfoboxQA for answer selection.\nThese corpora make it possible to evaluate the robustness of statistical question answering learning. Although all of these corpora target on selection-based QA, they are designed for different purposes such that it is important to understand the nature of these corpora so a better use of them can be made. In this paper, we make both intrinsic and extrinsic analyses of four latest corpora based on Wikipedia, WikiQA, SelQA, SQuAD, and InfoboxQA. We first give a thorough intrinsic analysis regarding contextual similarities, question types, and answer categories (Section SECREF2 ). We then map questions in all corpora to the current version of English Wikipedia and benchmark another selection-based QA task, answer retrieval (Section SECREF3 ). Finally, we present an extrinsic analysis through a set of experiments cross-testing these corpora using a convolutional neural network architecture (Section SECREF4 ).\nRecently, various QA tasks that are not selection-based have been proposed (Reddy and Bandyopadhyay, 2006; Hosseini et al., 2014; Jauhar et al., 2016; Sachan et al., 2016); however, selection-based QA remains still important because of its practical value to real applications (e.g., IBM Watson, MIT START).",

The weave is essentially how tight the screen is woven and how large the holes in the screen are. For more detailed designs, the screen used will be woven very close and tight so the holes are very small and let less ink through. This allows for very thin lines and detail. Each screen can print 1 color at a time. So, to print a design with multiple colors, there needs to be multiple screens. 1 screen per color.

The ILP framework, being extractive in nature, has demonstrated considerable success on a number of summarization tasks BIBREF20 , BIBREF21 . It generates a summary by selecting a set of sentences from the source documents. The sentences shall maximize the coverage of important source content, while minimizing the redundancy among themselves. At the heart of the algorithm is a sentence-concept co-occurrence matrix, used to determine if a sentence contains important concepts and whether two sentences share the same concepts. We introduce a low-rank approximation to the co-occurrence matrix and optimize it using the proximal gradient method. The resulting system thus allows different sentences to share co-occurrence statistics. For example, “The activity with the bicycle parts\" will be allowed to partially contain “bike elements\" although the latter phrase does not appear in the sentence. The low-rank matrix approximation provides an effective way to implicitly group lexically-diverse but semantically-similar expressions. It can handle out-of-vocabulary expressions and domain-specific terminologies well, hence being a more principled approach than heuristically calculating similarities of word embeddings.\nIn this work, we propose to augment the integer linear programming (ILP)-based summarization framework with a low-rank approximation of the co-occurrence matrix, and further evaluate the approach on a broad range of datasets exhibiting high lexical diversity.",

        "answer": "Representing the semantics of text documents in multi-lingual comparable corpora.",
        "evidence": "This research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora. We present a new approach to this problem, based on neural embeddings, and test it on the task of clustering texts into meaningful classes depending on their topics. The setting is unsupervised, meaning that one either does not have enough annotated data to train a supervised classifier or does not want to be limited with a pre-defined set of classes. There is a lot of sufficiently good approaches to this problem in the case of mono-lingual text collections, but the presence of multiple languages introduces complications.\nWhen a text collection contains documents in several languages, it becomes impractical to simply represent the documents as vectors of words occurring in them (\"bag-of-words\"), as the words surface forms are different, even in closely-related languages. Thus, one has to invent means to cross the inter-lingual gap and bring all documents to some sort of shared representation, without losing information about their topics or categories.\nOf course, one obvious way to solve this problem is to translate all documents into one language, and then apply any clustering algorithm. However, this requires either buying human/machine translation services (which can be expensive if you deal with large text collection) or training own statistical machine translation model (which as a rule requires big parallel corpus). This is the reason to search for other solutions.\nIn this paper, a novel way of reducing the problem of cross-lingual document representation to a monolingual setting is proposed. Essentially, we train Continuous Bag-of-Words models BIBREF0 on large comparable monolingual corpora for two languages our dataset consists of. This provides us with vector representations of words, allowing to measure their semantic similarity. Then, a linear transformation matrix from vectors of language A to vectors of language B is learned, using a small bilingual dictionary as training data. This matrix is then employed to `project' word and document representations from semantic space of language A to semantic space of language B. It allows not only quite accurate `translation' of words, but also of document `semantic fingerprints' (dense representations of document semantics, calculated as an average of the trained distributional vectors for all the words in document).\nThis approach is evaluated in a setting, where the input is a collection of documents in several languages and some number of topics to which these documents belong (we also have large monolingual corpora to train distributional models on). For each document, we are given its language, but not its topic. The task is to cluster this collection so that documents belonging to one topic were clustered together, independent of their language. Note that we are interested in clustering the collection as a whole, not each language separately (which is trivial).\nOur evaluation data consists of comparable corpora of Russian and Ukrainian academic texts. On this material, we show that the `translated semantic fingerprints' method represents documents in different languages precisely enough to allow almost exact clustering according to document topics, with only 5% of incorrect assignments. It significantly outperforms both naive bag-of-words baseline and the not-so-naive method of `orthographic translation' based on Damerau-Levenshtein distance, even enriched with dictionary mappings. At the same time, it does not require large parallel corpora or a ready-made statistical machine translation model.\nThe rest of the paper is structured as follows. In Section \"Related Work\" we describe the foundations of our approach and the related work. Section \"Academic texts as Comparable Corpora\" introduces the employed corpora and the story behind them. Section \"Learning to Translate: Ukrainian-to-Russian transformations\" is dedicated to learning the transformation matrix, and Section \"Experiment Design and Evaluation\" describes our experimental setting and evaluation results. We discuss the findings in Section \"Discussion\" and conclude in Section \"Conclusion and Future Work\" , also suggesting directions for future work.\nThis research addresses the problem of representing the semantics of text documents in multi-lingual comparable corpora.",

He was a descendant of the principal sachems of the Mohegans, Pequots, and Narragansetts. Owaneco presided over the village known as Montonesuck. Uncas was bilingual, learning Mohegan and some English, and possibly some Dutch.\n\nIn 1626, Owaneco arranged for Uncas to marry the daughter of the principal Pequot sachem Tatobem to secure an alliance with them. Owaneco died shortly after this marriage, and Uncas had to submit to Tatobem's authority. Tatobem was captured and killed by the Dutch in 1633; Sassacus became his successor, but Uncas felt that he deserved to be sachem.\n\nOwaneco's alliance with Tatobem was based upon a balance of power between the Mohegans and Pequots. After the death of Owaneco, the balance changed in favour of the Pequots. Uncas was unwilling to challenge the power of Tatobem; however, Uncas did begin contesting Pequot authority over the Mohegans. In 1634 with Narragansett support, Uncas rebelled against Sassacus and Pequot authority. Uncas was defeated and became an exile among the Narragansetts. He soon returned from exile after ritually humiliating himself before Sassacus. His failed challenges resulted in Uncas having little land and few followers, but Uncas saw that the newly arriving Puritan colonists, though few in number, had better weapons and much courage, so he started to develop a new strategy and alliance to work towards his ultimate goal of Grand Sachem.",

        "question": "What is the \"Interlingua\" ?",
        "answer": "It was the connector of both natural languages, and was used to model common-sense human knowledge.",
        "evidence": "In this paper, we are exploring the historical significance of Croatian machine translation research group. The group was active in 1950s, and it was conducted by Bulcsu Laszlo, Croatian linguist, who was a pioneer in machine translation during the 1950s in Yugoslavia.\nTo put the research of the Croatian group in the right context, we have to explore the origin of the idea of machine translation. The idea of machine translation is an old one, and its origin is commonly connected with the work of Rene Descartes, i.e. to his idea of universal language, as described in his letter to Mersenne from 20.xi.1629 BIBREF0. Descartes describes universal language as a simplified version of the language which will serve as an “interlanguage” for translation. That is, if we want to translate from English to Croatian, we will firstly translate from English to an “interlanguage”, and then from the “interlanguage” to Croatian. As described later in this paper, this idea had been implemented in the machine translation process, firstly in the Indonesian-to-Russian machine translation system created by Andreev, Kulagina and Melchuk from the early 1960s.\nIn modern times, the idea of machine translation was put forth by the philosopher and logician Yehoshua Bar-Hillel (most notably in BIBREF1 and BIBREF2), whose papers were studied by the Croatian group. Perhaps the most important unrealized point of contact between machine translation and cybernetics happened in the winter of 1950/51. In that period, Bar-Hillel met Rudolf Carnap in Chicago, who introduced to him the (new) idea of cybernetics. Also, Carnap gave him the contact details of his former teaching assistant, Walter Pitts, who was at that moment with Norbert Wiener at MIT and who was supposed to introduce him to Wiener, but the meeting never took place BIBREF3. Nevertheless, Bar-Hillel was to stay at MIT where he, inspired by cybernetics, would go to organize the first machine translation conference in the world in 1952 BIBREF3.\nThe idea of machine translation was a tempting idea in the 1950s. The main military interest in machine translation as an intelligence gathering tool (translation of scientific papers, daily press, technical reports, and everything the intelligence services could get their hands on) was sparked by the Soviet advance in nuclear technology, and would later be compounded by the success of Vostok 1 (termed by the USA as a “strategic surprise”). In the nuclear age, being able to read and understand what the other side was working on was of crucial importance BIBREF4. Machine translation was quickly absorbed in the program of the Dartmouth Summer Research Project on Artificial Intelligence in 1956 (where Artificial Intelligence as a field was born), as one of the five core fields of artificial intelligence (later to be known as natural language processing). One other field was included here, the “nerve nets” as they were known back then, today commonly known as artificial neural networks. What is also essential for our discussion is that the earliest programming language for artificial intelligence, Lisp, was invented in 1958 by John McCarthy BIBREF5. But let us take a closer look at the history of machine translation. In the USA, the first major wave of government and military funding for machine translation came in 1954, and the period of abundancy lasted until 1964, when the National Research Council established the Automatic Language Processing Advisory Committee (ALPAC), which was to assess the results of the ten years of intense funding. The findings were very negative, and funding was almost gone BIBREF4, hence the ALPAC report became the catalyst for the first “AI Winter”.\nOne of the first recorded attempts of producing a machine translation system in the USSR was in 1954 BIBREF6, and the attempt was applauded by the Communist party of the Soviet Union, by the USSR Committee for Science and Technology and the USSR Academy of Sciences. The source does not specify how this first system worked, but it does delineate that the major figures of machine translation of the time were N. Andreev of the Leningrad State University, O. Kulagina and I. Melchuk of the Steklov Mathematical Institute. There is information on an Indonesian-to-Russian machine translation system by Andreev, Kulagina and Melchuk from the early 1960s, but it is reported that the system was ultimately a failure, in the same way early USA systems were. The system had statistical elements set forth by Andreev, but the bulk was logical and knowledge-heavy processing put forth by Kulagina and Melchuk. The idea was to have a logical intermediate language, under the working name “Interlingua”, which was the connector of both natural languages, and was used to model common-sense human knowledge. For more details, see BIBREF6.\nIn the USSR, there were four major approaches to machine translation in the late 1950s BIBREF7. The first one was the research at the Institute for Precise Mechanics and Computational Technology of the USSR Academy of Sciences. Their approach was mostly experimental and not much different from today's empirical methods. They evaluated the majority of algorithms known at the time algorithms over meticulously prepared datasets, whose main strength was data cleaning, and by 1959 they have built a German-Russian machine translation prototype. The second approach, as noted by Mulić BIBREF7, was championed by the team at the Steklov Mathematical Institute of the USSR Academy of Sciences led by A. A. Reformatsky. Their approach was mainly logical, and they extended the theoretical ideas of Bar-Hillel BIBREF2 to build three algorithms: French-Russian, English-Russian and Hungarian-Russian. The third and perhaps the most successful approach was the one by A. A. Lyapunov, O. S. Kulagina and R. L. Dobrushin. Their efforts resulted in the formation of the Mathematical Linguistics Seminar at the Faculty of Philology in Moscow in 1956 and in Leningrad in 1957. Their approach was mainly information-theoretic (but they also tried logic-based approaches BIBREF7), which was considered cybernetic at that time. This was the main role model for the Croatian efforts from 1957 onwards. The fourth, and perhaps most influential, was the approach at the Experimental Laboratory of the Leningrad University championed by N. D. Andreev BIBREF7. Here, the algorithms for Indonesian-Russian, Arabic-Russian, Hindu-Russian, Japanese-Russian, Burmese-Russian, Norwegian-Russian, English-Russian, Spanish-Russian and Turkish-Russian were being built. The main approach of Andreev's group was to use an intermediary language, which would capture the meanings BIBREF7. It was an approach similar to KL-ONE, which would be introduced in the West much later (in 1985) by Brachman and Schmolze BIBREF8. It is also interesting to note that the Andreev group had a profound influence on the Czechoslovakian machine translation program BIBREF9, which unfortunately suffered a similar fate as the Yugoslav one due to the lack of funding.\nAndreev's approach was in a sense \"external\". The modelling would be statistical, but its purpose would not be to mimic the stochasticity of the human thought process, but rather to produce a working machine translation system. Kulagina and Melchuk disagreed with this approach as they thought that more of what is presently called \"philosophical logic\" was needed to model the human thought process at the symbolic level, and according to them, the formalization of the human thought process was a prerequisite for developing a machine translation system (cf. BIBREF6). We could speculate that sub-symbolic processing would have been acceptable too, since that approach is also rooted in philosophical logic as a way of formalizing human cognitive functions and is also \"internal\" in the same sense symbolic approaches are.\nThere were many other centers for research in machine translation: Gorkovsky University (Omsk), 1st Moscow Institute for Foreign Languages, Computing Centre of the Armenian SSR and at the Institute for Automatics and Telemechanics of the Georgian SSR BIBREF7. It is worthwhile to note that both the USA and the USSR had access to state-of-the-art computers, and the political support for the production of such systems meant that computers were made available to researchers in machine translation. However, the results were poor in the late 1950s, and a working system was yet to be shown. All work was therefore theoretical work implemented on a computer, which proved to be sub-optimal.\nThe idea was to have a logical intermediate language, under the working name “Interlingua”, which was the connector of both natural languages, and was used to model common-sense human knowledge.",

        "answer": "Their proposed architecture can learn temporal and sequential data with longer dependencies between each input time-step than simple RNNs without gating units and combine the gating units with tensor products to represent the hidden layer with more powerful operation and direct interaction.",
        "evidence": "Modeling temporal and sequential data, which is crucial in machine learning, can be applied in many areas, such as speech and natural language processing. Deep neural networks (DNNs) have garnered interest from many researchers after being successfully applied in image classification BIBREF0 and speech recognition BIBREF1 . Another type of neural network, called a recurrent neural network (RNN) is also widely used for speech recognition BIBREF2 , machine translation BIBREF3 , BIBREF4 and language modeling BIBREF5 , BIBREF6 . RNNs have achieved many state-of-the-art results. Compared to DNNs, they have extra parameters for modeling the relationships of previous or future hidden states with current input where the RNN parameters are shared for each input time-step.\nGenerally, RNNs can be separated by a simple RNN without gating units, such as the Elman RNN BIBREF7 , the Jordan RNN BIBREF8 , and such advanced RNNs with gating units as the Long-Short Term Memory (LSTM) RNN BIBREF9 and the Gated Recurrent Unit (GRU) RNN BIBREF4 . A simple RNN usually adequate to model some dataset and a task with short-term dependencies like slot filling for spoken language understanding BIBREF10 . However, for more difficult tasks like language modeling and machine translation where most predictions need longer information and a historical context from each sentence, gating units are needed to achieve good performance. With gating units for blocking and passing information from previous or future hidden layer, we can learn long-term information and recursively backpropagate the error from our prediction without suffering from vanishing or exploding gradient problems BIBREF9 . In spite of this situation, the concept of gating mechanism does not provide an RNN with a more powerful way to model the relation between the current input and previous hidden layer representations.\nMost interactions inside RNNs between current input and previous (or future) hidden states are represented using linear projection and addition and are transformed by the nonlinear activation function. The transition is shallow because no intermediate hidden layers exist for projecting the hidden states BIBREF11 . To get a more powerful representation on the hidden layer, Pascanu et al. BIBREF11 modified RNNs with an additional nonlinear layer from input to the hidden layer transition, hidden to hidden layer transition and also hidden to output layer transition. Socher et al. BIBREF12 , BIBREF13 proposed another approach using a tensor product for calculating output vectors given two input vectors. They modified a Recursive Neural Network (RecNN) to overcome those limitations using more direct interaction between two input layers. This architecture is called a Recursive Neural Tensor Network (RecNTN), which uses a tensor product between child input vectors to represent the parent vector representation. By adding the tensor product operation to calculate their parent vector, RecNTN significantly improves the performance of sentiment analysis and reasoning on entity relations tasks compared to standard RecNN architecture. However, those models struggle to learn long-term dependencies because the do not utilize the concept of gating mechanism.\nIn this paper, we proposed a new RNN architecture that combine the gating mechanism and tensor product concepts to incorporate both advantages in a single architecture. Using the concept of such gating mechanisms as LSTMRNN and GRURNN, our proposed architecture can learn temporal and sequential data with longer dependencies between each input time-step than simple RNNs without gating units and combine the gating units with tensor products to represent the hidden layer with more powerful operation and direct interaction. Hidden states are generated by the interaction between current input and previous (or future) hidden states using a tensor product and a non-linear activation function allows more expressive model representation. We describe two different models based on LSTMRNN and GRURNN. LSTMRNTN is our proposed model for the combination between a LSTM unit with a tensor product inside its cell equation and GRURNTN is our name for a GRU unit with a tensor product inside its candidate hidden layer equation.\nIn Section \"Background\" , we provide some background information related to our research. In Section \"Proposed Architecture\" , we describe our proposed RNN architecture in detail. We evaluate our proposed RNN architecture on word-level and character-level language modeling tasks and reported the result in Section \"Experiment Settings\" . We present related works in Section \"Related Work\" . Section \"Conclusion\" summarizes our paper and provides some possible future improvements.\nUsing the concept of such gating mechanisms as LSTMRNN and GRURNN, our proposed architecture can learn temporal and sequential data with longer dependencies between each input time-step than simple RNNs without gating units and combine the gating units with tensor products to represent the hidden layer with more powerful operation and direct interaction.",

The program was written using the MLISP language (meta-lisp) on the WAITS operating system running on a DEC PDP-10 and the code is non-portable. Parts of it were written in PDP-10 assembly code and others in MLISP. There may be other parts that require other language translators. PARRY was the first system to pass the Turing test - the psychiatrists were able to make the correct identification only 48 percent of the time, which is the same as a random guessing.\nA.L.I.C.E.

        "evidence": "While the demand for physical and manual labor is gradually declining, there is a growing need for a workforce with soft skills. Which soft skill do you think would be the most valuable in your daily life? According to an article in Forbes BIBREF0 , 70% of employed Americans agree that public speaking skills are critical to their success at work. Yet, it is one of the most dreaded acts. Many people rate the fear of public speaking even higher than the fear of death BIBREF1 . To alleviate the situation, several automated systems are now available that can quantify behavioral data for participants to reflect on BIBREF2 . Predicting the viewers' ratings from the speech transcripts would enable these systems to generate feedback on the potential audience behavior.\nPredicting human behavior, however, is challenging due to its huge variability and the way the variables interact with each other. Running Randomized Control Trials (RCT) to decouple each variable is not always feasible and also expensive. It is possible to collect a large amount of observational data due to the advent of content sharing platforms such as YouTube, Massive Open Online Courses (MOOC), or ted.com. However, the uncontrolled variables in the observational dataset always keep a possibility of incorporating the effects of the “data bias” into the prediction model. Recently, the problems of using biased datasets are becoming apparent. BIBREF3 showed that the error rates in the commercial face-detectors for the dark-skinned females are 43 times higher than the light-skinned males due to the bias in the training dataset. The unfortunate incident of Google's photo app tagging African-American people as “Gorilla” BIBREF4 also highlights the severity of this issue.\nWe address the data bias issue as much as possible by carefully analyzing the relationships of different variables in the data generating process. We use a Causal Diagram BIBREF5 , BIBREF6 to analyze and remove the effects of the data bias (e.g., the speakers' reputations, popularity gained by publicity, etc.) in our prediction model. In order to make the prediction model less biased to the speakers' race and gender, we confine our analysis to the transcripts only. Besides, we normalize the ratings to remove the effects of the unwanted variables such as the speakers' reputations, publicity, contemporary hot topics, etc.\nFor our analysis, we curate an observational dataset of public speech transcripts and other meta-data collected from the ted.com website. This website contains a large collection of high-quality public speeches that are freely available to watch, share, rate, and comment on. Every day, numerous people watch and annotate their perceptions about the talks. Our dataset contains 2231 public speech transcripts and over 5 million ratings from the spontaneous viewers of the talks. The viewers annotate each talk by 14 different labels—Beautiful, Confusing, Courageous, Fascinating, Funny, Informative, Ingenious, Inspiring, Jaw-Dropping, Long-winded, Obnoxious, OK, Persuasive, and Unconvincing.\nWe use two neural network architectures in the prediction task. In the first architecture, we use LSTM BIBREF7 for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM BIBREF8 to represent the input sentences in the form of a dependency tree. Our experiments show that the dependency tree-based model can predict the TED talk ratings with slightly higher performance (average F-score 0.77) than the word sequence model (average F-score 0.76). To the best of our knowledge, this is the best performance in the literature on predicting the TED talk ratings. We compare the performances of these two models with a baseline of classical machine learning techniques using hand-engineered features. We find that the neural networks largely outperform the classical methods. We believe this gain in performance is achieved by the networks' ability to capture better the natural relationship of the words (as compared to the hand engineered feature selection approach in the baseline methods) and the correlations among different rating labels.\nIn the first architecture, we use LSTM (Hochreiter and Schmidhuber, 1997) for a sequential input of the words within the sentences of the transcripts. In the second architecture, we use TreeLSTM (Tai et al., 2015) to represent the input sentences in the form of a dependency tree.",

Experimental results showed that the proposed multilingual approach outperforms both the majority baseline and the lexicon-based baseline.\nIn this paper we made the sentiment analysis model specific to a single domain.

        "answer": "Simón José Antonio de la Santísima Trinidad Bolívar y Palacios (24 July 1783 – 17 December 1830) was a Venezuelan military and political leader who led what are currently the countries of Colombia, Venezuela, Ecuador, Peru, Panama and Bolivia to independence from the Spanish Empire. He is known colloquially as El Libertador, or the Liberator of America.\n\nSimón Bolívar was born in Caracas in the Captaincy General of Venezuela into a wealthy family of American-born Spaniards (criollo), but lost both parents as a child. Bolívar was educated abroad and lived in Spain, as was common for men of upper-class families in his day. While living in Madrid from 1800 to 1802, he was introduced to Enlightenment philosophy and married María Teresa Rodríguez del Toro y Alaysa, who died in Venezuela from yellow fever in 1803. From 1803 to 1805, Bolívar embarked on a Grand Tour that ended in Rome, where he swore to end the Spanish rule in the Americas. In 1807, Bolívar returned to Venezuela and proposed gaining Venezuelan independence to other wealthy creoles. When the Spanish authority in the Americas weakened due to Napoleon's Peninsular War, Bolívar became a zealous combatant and politician in the Spanish American wars of independence.\n\nBolívar began his military career in 1810 as a militia officer in the Venezuelan War of Independence, fighting Royalist forces for the first and second Venezuelan republics and the United Provinces of New Granada. After Spanish forces subdued New Granada in 1815, Bolívar was forced into exile on Jamaica. In Haiti, Bolívar met and befriended Haitian revolutionary leader Alexandre Pétion. After promising to abolish slavery in Spanish America, Bolívar received military support from Pétion and returned to Venezuela. He established a third republic in 1817 and then crossed the Andes to liberate New Granada in 1819. Bolívar and his allies defeated the Spanish in New Granada in 1819, Venezuela and Panama in 1821, Ecuador in 1822, Peru in 1824, and Bolivia in 1825. Venezuela, New Granada, Ecuador, and Panama were merged into the Republic of Colombia (Gran Colombia), with Bolívar as president there and in Peru and Bolivia.\n\nIn his final years, Bolívar became increasingly disillusioned with the South American republics, and distanced from them because of his centralist ideology. He was successively removed from his offices until he resigned the presidency of Colombia and died of tuberculosis in 1830. His legacy is diverse and far-reaching within Latin America and beyond. He is regarded as a national and cultural icon throughout Latin America; the nations of Bolivia and Venezuela (as the Boliviarian Republic of Venezuela) are named after him, and he has been memorialized all over the world in the form of public art or street names and in popular culture.",

        "question": "What is an essential factor in modeling the popularity of online petitions shown by them?",
        "answer": "Discourse structure.",
        "evidence": "Natural language generation and document classification have been widely conducted using neural sequence models based on the encoder–decoder architecture. The underlying technique relies on the production of a context vector as the document representation, to estimate both tokens in natural language generation and labels in classification tasks. By combining recurrent neural networks with attention BIBREF0, the model is able to learn contextualized representations of words at the sentence level. However, higher-level concepts, such as discourse structure beyond the sentence, are hard for an RNN to learn, especially for longer documents. We hypothesize that NLP tasks such as summarization and document classification can be improved through the incorporation of discourse information.\nIn this paper, we propose to incorporate latent representations of discourse units into neural training. A discourse parser can provide information about the document structure as well as the relationships between discourse units. In a summarization scenario, for example, this information may help to remove redundant information or discourse disfluencies. In the case of document classification, the structure of the text can provide valuable hints about the document category. For instance, a scientific paper follows a particular discourse narrative pattern, different from a short story. Similarly, we may be able to predict the societal influence of a document such as a petition document, in part, from its discourse structure and coherence.\nSpecifically, discourse analysis aims to identify the organization of a text by segmenting sentences into units with relations. One popular representation is Rhetorical Structure Theory (RST) proposed by mann1988rhet, where the document is parsed into a hierarchical tree, where leaf nodes are the segmented units, known as Entity Discourse Units (EDUs), and non-terminal nodes define the relations.\nAs an example, in Figure FIGREF1 the two-sentence text has been annotated with discourse structure based on RST, in the form of 4 EDUs connected with discourse labels attr and elab. Arrows in the tree capture the nuclearity of relations, wherein a “satellite” points to its “nucleus”. The Nucleus unit is considered more prominent than the Satellite, indicating that the Satellite is a supporting sentence for the Nucleus. Nuclearity relationships between two EDUs can take the following three forms: Nucleus–Satellite, Satellite–Nucleus, and Nucleus–Nucleus. In this work, we use our reimplementation of the state of the art neural RST parser of BIBREF1, which is based on eighteen relations: purp, cont, attr, evid, comp, list, back, same, topic, mann, summ, cond, temp, eval, text, cause, prob, elab.\nThis research investigates the impact of discourse representations obtained from an RST parser on natural language generation and document classification. We primarily experiment with an abstractive summarization model in the form of a pointer–generator network BIBREF2, focusing on two factors: (1) whether summarization benefits from discourse parsing; and (2) how a pointer–generator network guides the summarization model when discourse information is provided. For document classification, we investigate the content-based popularity prediction of online petitions with a deep regression model BIBREF3. We argue that document structure is a key predictor of the societal influence (as measured by signatures to the petition) of a document such as a petition.\nOur primary contributions are as follows: (1) we are the first to incorporate a neural discourse parser in sequence training; (2) we empirically demonstrate that a latent representation of discourse structure enhances the summaries generated by an abstractive summarizer; and (3) we show that discourse structure is an essential factor in modelling the popularity of online petitions.\n(3) we show that discourse structure is an essential factor in modelling the popularity of online petitions.",

        "answer": "Briefly speaking, the original adversarial learning adds an additional discriminator to classify the type of source inputs.",
        "evidence": "Adversarial learning has been an effective mechanism to resolve the problem of the input features between the training and test examples having large divergences BIBREF27 , BIBREF13 . It has been successfully applied on domain adaption BIBREF7 , cross-lingual learning BIBREF15 and multi-task learning BIBREF17 . All settings involve feature shifting between the training and testing.\nIn this paper, our setting is different. We are using the annotations from non-experts, which are noise and can influence the final performances if they are not properly processed. Directly learning based on the resulting corpus may adapt the neural feature extraction into the biased annotations. In this work, we assume that individual workers have their own guidelines in mind after short training. For example, a perfect worker can annotate highly consistently with an expert, while common crowdsourcing workers may be confused and have different understandings on certain contexts. Based on the assumption, we make an adaption for the original adversarial neural network to our setting.\nOur adaption is very simple. Briefly speaking, the original adversarial learning adds an additional discriminator to classify the type of source inputs, for example, the domain category in the domain adaption setting, while we add a discriminator to classify the annotation workers. Solely the features from the input sentence is not enough for worker classification. The annotation result of the worker is also required. Thus the inputs of our discriminator are different. Here we exploit both the source sentences and the crowd-annotated NE labels as basic inputs for the worker discrimination.\nIn the following, we describe the proposed adversarial learning module, including both the submodels and the training method. As shown by the left part of Figure 1 , the submodel consists of four parts: (1) a common Bi-LSTM over input characters; (2) an additional Bi-LSTM to encode crowd-annotated NE label sequence; (3) a convolutional neural network (CNN) to extract features for worker discriminator; (4) output and prediction.\nOur adaption is very simple.

        "evidence": "Figure FIGREF31 shows the evaluation of our approach when discovering new informative keywords for model training (see Section SECREF2: Keyword Discovery). We compare our human-AI collaborative way of discovering new keywords against a query expansion (QE) approach BIBREF23, BIBREF24 that leverages word embeddings to find similar words in the latent semantic space. Specifically, we use pre-trained word embeddings based on a large Google News dataset for query expansion. For instance, the top keywords resulting from QE for `politician' are, `deputy',`ministry',`secretary', and `minister'. For each of these keywords, we use the crowd to label a set of tweets and obtain a corresponding expectation.\nWe observe that our approach consistently outperforms QE by an average of $4.62\\%$ and $52.58\\%$ AUC on CyberAttack and PoliticianDeath, respectively. The large gap between the performance improvements for the two datasets is mainly due to the fact that microposts that are relevant for PoliticianDeath are semantically more complex than those for CyberAttack, as they encode noun-verb relationship (e.g., “the king of ... died ...”) rather than a simple verb (e.g., “... hacked.”) for the CyberAttack microposts. QE only finds synonyms of existing keywords related to either `politician' or `death', however cannot find a meaningful keyword that fully characterizes the death of a politician. For instance, QE finds the keywords `kill' and `murder', which are semantically close to `death' but are not specifically relevant to the death of a politician. Unlike QE, our approach identifies keywords that go beyond mere synonyms and that are more directly related to the end task, i.e., discriminating event-related microposts from non related ones. Examples are `demise' and `condolence'. As a remark, we note that in Figure FIGREF31(b), the increase in QE performance on PoliticianDeath is due to the keywords `deputy' and `minister', which happen to be highly indicative of the death of a politician in our dataset; these keywords are also identified by our approach.\nSpecifically, we use pre-trained word embeddings based on a large Google News dataset2 for query expansion.",

        "question": "In this reference text summarizing plot of the book The High King, how did the sword Dyrnwyn lose its power?",
        "evidence": "The story begins only days after the conclusion of Taran Wanderer. With winter approaching, Taran and his companion Gurgi return from their wanderings to Caer Dallben after getting news from Kaw the crow that Princess Eilonwy has returned from the Isle of Mona. Indeed, they find her at home, along with her escort King Rhun of Mona and the former giant Glew, who had been magically restored to human size by a potion from Dallben.\n\nBefore Taran can propose to Eilonwy, the bard-king Fflewddur Fflam and his mount Llyan arrive with a gravely injured Gwydion, Prince of Don. Servants of Arawn had assaulted them and seized the magical black sword Dyrnwyn. Fflewddur also states that Taran was involved in the ambush, baffling everyone. With Achren's help, the truth is determined: Arawn himself has come from Annuvin to the verge of Caer Dallben in the guise of Taran, in order to lure Gwydion into the ambush.\n\nBecause Dyrnwyn may be pivotal as a threat to Arawn, Dallben consults the oracular pig Hen Wen to determine how it may be regained. During the reading, the ash rods used to communicate shatter and the two thirds of Hen Wen's answer are discouraging and vague. When Gwydion heals sufficiently, he sets out with Taran and others to meet with King Smoit. Gwydion insists that he alone should enter Annuvin to seek the sword, but Smoit's Cantrev Cadiffor is on the way. The small party divides, as Rhun and Eilonwy intend to visit the ships of Mona en route.\n\nWhen Gwydion, Taran, and others reach Caer Cadarn, they are imprisoned by Magg, the treacherous former Chief Steward of Mona, who has entered service with Arawn and taken over the fortress. When Eilonwy approaches with the other party, she detects something amiss and they cautiously send Fflewddur Fflam to the fortress as a bard. After entertaining the soldiers for a night, he returns with the bad news. Then the companions encounter Gwystyl of the Fair Folk outside the stronghold, en route home after closing the waypost near Annuvin, personally bearing final observations to King Eiddileg about preparations for war by Arawn's forces. With Gwystyl's assistance and store of magical smokes, fires, and concealments, the companions break in and free the prisoners. The plan goes awry, however; King Smoit and his men are finally able to regain control only by Rhun's intervention, which costs his life.\n\nLearning from Gwystyl of the activities in Annuvin, Gwydion turns from the quest for Dyrnwyn to planning for battle at Caer Dathyl. Gwystyl, Fflewddur, and Taran leave to gather support, respectively from the Fair Folk, the northern realms, and the Free Commots. Kaw, sent out by Taran to reconnoiter the enemy, is attacked by Gwythaints while spying near Annuvin, but manages to reach Medwyn, who asks all the creatures of air and land to oppose the forces of Arawn. Taran, Coll, Eilonwy, and Gurgi muster the Commots, who rally to their friendship with Taran, and sends them marching in groups to Caer Dathyl while the smiths and weavers rallied by Hevydd and Dwyvach work day and night to equip them.\n\nSoon after Taran and the last Commots reach Caer Dathyl, King Pryderi arrives from the western realms. In council he announces his new allegiance to Arawn, for the good of all, because \"Arawn will do what the Sons of Don have failed to do: Make an end of endless wars among the cantrevs, and bring peace where there was none before.\" He is rejected utterly but permitted to return unharmed to his army, and at the next day the battle begins. Although the Sons of Don and allies initially have the best of it, the Cauldron-Born arrive en masse before evening, overwhelming the allies and razing Caer Dathyl to the ground.\n\nWith High King Math killed, Gwydion is proclaimed the new High King. With the bulk of the Cauldron-Born deployed outside of Annuvin, Gwydion determines that the best chance is to attack while it is guarded by mortal men alone. He will lead the Sons of Don to waiting ships on the north coast and attack by sea, while Taran leads the Commots to delay the Cauldron-Born's return march, as their power wanes with time and distance from Annuvin.\n\nTaran and his army are able to hold the tired Cauldron-Born warriors beyond arm's length by brute force, and turn the march from a straight and easy route into the rugged hills, although Coll dies in battle. Thanks to a company of Fair Folk, and to the animals sent by Medwyn, they destroy most of the Huntsmen who accompany and lead the undead. At last the Cauldron-Born break free of the hills and return to the lowland route. Regaining strength as they near Annuvin, it would be futile for the exhausted allies to meet them head-on again, so inevitably they take the long, easy route to Arawn's stronghold.\n\nTaran and the remainder of his army finally reach Annuvin by a combination of the direct route, a mountain path of Doli's, and a secret pass over Mount Dragon shown to them by Achren. Taran sees that victory is nearly in Gwydion's hands, but also that the Cauldron-Born are about to reach Annuvin. In his alarm, Taran nearly falls off Mount Dragon, but is saved by the now-grown Gwythaint he had rescued so many years ago (The Book of Three). In a desperate attempt to fight off a group of Cauldron-Born who have discovered him on the mountain, he rolls a rock at them, and discovers Dyrnwyn in the hollow the stone occupied. Wielding Dyrnwyn, Taran slays the undead warrior who approaches to slay him, and at that instant all of the Cauldron-Born die as one.\n\nTaran's group enters the fray, and the battle continues through the halls of Annuvin. Taran is almost deceived by Arawn - who has taken the guise of Gwydion - into giving up the sword. After the chaotic defeat of Arawn's forces, the companions gather before the Great Hall. Achren identifies Arawn in the form of a nearby serpent preparing to strike Taran and grabs him. He strikes her fatally, but Taran kills him with Dyrnwyn. With the death of Arawn, the stronghold of Annuvin bursts in flame and falls in ruins, destroying all of the magical implements inside; only Gurgi manages to save several scrolls containing knowledge of farming, smithing, and other crafts. The sword Dyrnwyn begins to fade, losing its magic.\n\nThe allies travel to Caer Dallben, where Gwydion tells them that in victory the Sons of Don, with all kinsmen and kinswomen, must return to the Summer Country. Indeed, all those who still have magic will depart, and the Fair Folk and Medwyn have closed their realms to outsiders. Dallben and Eilonwy must also go, and others who have served well, Taran among them, are given the chance to accompany them. Taran proposes to Eilonwy at last, and she accepts.\n\nThe Sons of Don plan to leave the next day. However, Taran becomes uncomfortable about his decision overnight. The witches Orddu, Orwen and Orgoch appear before him and reveal that they too are departing, and leave him with an unfinished tapestry depicting his life. He realizes there is much work to be done to rebuild Prydain, and he has made many promises; so he determines to remain behind. Eilonwy is able to willingly give up her magical nature in order to remain with him, and the two are married.\n\nDallben reveals that with this last quest, Taran has completed a path prophesied in the Book of Three whereby an orphan of \"no station in life\" would succeed the Sons of Don as High King. Dallben had traveled to seek such a one and try to hasten the day of Arawn's defeat; on this journey, he found a baby, hidden in the trees beside a battlefield and without any token of parentage, and took it in under the name Taran. Taran receives many gifts, including The Book of Three itself, although its powers, like all magic in Prydain, have also faded away with Arawn's demise, leaving it only as a mere chronicle of Taran's life. With Eilonwy by his side, Taran accepts his new responsibility and is hailed by his friends and battle companions as the new High King.",

Moreover, since the distribution of the channel is expected to change frequently (e.g., a wireless link), the error rate of the autoencoder can degrade quickly, making it challenging to collect sufficient data for frequent retraining of the autoencoder. To address this, we propose a fast and sample-efficient method for adapting the autoencoder without modifying the encoder and decoder neural networks, and adapting only the MDN channel model. The method utilizes feature transformations at the decoder to compensate for changes in the channel distribution, and effectively present to the decoder samples close to the source distribution. Experimental evaluation on simulated datasets and real mmWave wireless channels demonstrate that the proposed method can adapt the MDN channel using very limited number of samples, and improve or maintain the error rate of the autoencoder under changing channel conditions.\nThe problem of end-to-end learning of a communication system using an autoencoder has recently been shown to be a promising approach.

        "answer": "A model based on dynamic entity representation at decoding time.",
        "evidence": "Until recently, efforts to bring out semantics from structured-data relied heavily on expert knowledge BIBREF22, BIBREF8. For example, in order to better transcribe numerical time series of weather data to a textual forecast, Reiter et al. BIBREF8 devise complex template schemes in collaboration with weather experts to build a consistent set of data-to-word rules.\nModern approaches to the wide range of tasks based on structured-data (e.g. table retrieval BIBREF2, BIBREF23, table classification BIBREF24, question answering BIBREF25) now propose to leverage progress in deep learning to represent these data into a semantic vector space (also called embedding space). In parallel, an emerging task, called “data-to-text\", aims at describing structured data into a natural language description. This task stems from the neural machine translation (NMT) domain, and early work BIBREF26, BIBREF27, BIBREF10 represent the data records as a single sequence of facts to be entirely translated into natural language. Wiseman et al. BIBREF10 show the limits of traditional NMT systems on larger structured-data, where NMT systems fail to accurately extract salient elements.\nTo improve these models, a number of work BIBREF28, BIBREF12, BIBREF29 proposed innovating decoding modules based on planning and templates, to ensure factual and coherent mentions of records in generated descriptions. For example, Puduppully et al. BIBREF12 propose a two-step decoder which first targets specific records and then use them as a plan for the actual text generation. Similarly, Li et al. BIBREF28 proposed a delayed copy mechanism where their decoder also acts in two steps: 1) using a classical LSTM decoder to generate delexicalized text and 2) using a pointer network BIBREF30 to replace placeholders by records from the input data.\nCloser to our work, very recent work BIBREF11, BIBREF19, BIBREF13 have proposed to take into account the data structure. More particularly, Puduppully et al. BIBREF13 follow entity-centric theories BIBREF31, BIBREF32 and propose a model based on dynamic entity representation at decoding time. It consists in conditioning the decoder on entity representations that are updated during inference at each decoding step. On the other hand, Liu et al. BIBREF11, BIBREF19 rather focus on introducing structure into the encoder. For instance, they propose a dual encoder BIBREF19 which encodes separately the sequence of element names and the sequence of element values. These approaches are however designed for single-entity data structures and do not account for delimitation between entities.\nOur contribution differs from previous work in several aspects. First, instead of flatly concatenating elements from the data-structure and encoding them as a sequence BIBREF11, BIBREF12, BIBREF10, we constrain the encoding to the underlying structure of the input data, so that the delimitation between entities remains clear throughout the process. Second, unlike all works in the domain, we exploit the Transformer architecture BIBREF21 and leverage its particularity to directly compare elements with each others in order to avoid arbitrary assumptions on their ordering. Finally, in contrast to BIBREF33, BIBREF13 that use a complex updating mechanism to obtain a dynamic representation of the input data and its entities, we argue that explicit hierarchical encoding naturally guides the decoding process via hierarchical attention.\n\nMore particularly, Puduppully et al. [29] follow entity-centric theories [10,20] and propose a model based on dynamic entity representation at decoding time.",

In contrast, SNIP tends to prune much more of the earlier layers compared to the latter ones. Random pruning by default prunes each layer at approximately the same ratio. Comparing the three methods seems to suggest that to find effective and transferable LIP subnetworks, specifically keeping more weights at earlier layers more is important. That is an explainable finding, since for image restoration tasks, the low-level features (color, texture, shape, etc.) presumably matter more and are more transferable,  than the high-level features (object categories, etc.).

However, complex neural summarization models with thousands of parameters usually require a large amount of training data. In fact, much of the neural summarization work has been trained and tested in news domains where numerous large datasets exist. For example, the CNN/DailyMail (CNN/DM) BIBREF3, BIBREF4 and New York Times (NYT) datasets are in the magnitude of 300k and 700k documents, respectively. In contrast, in other domains such as student reflections, summarization datasets are only in the magnitude of tens or hundreds of documents (e.g., BIBREF5). We hypothesize that training complex neural abstractive summarization models in such domains will not yield good performing models, and we will indeed later show that this is the case for student reflections.\nTo improve performance in low resource domains, we explore three directions. First, we explore domain transfer for abstractive summarization. While domain transfer is not new, compared to prior summarization studies BIBREF6, BIBREF7, our training (news) and tuning (student reflection) domains are quite dissimilar, and the in-domain data is small. Second, we propose a template-based synthesis method to create synthesized summaries, then explore the effect of enriching training data for abstractive summarization using the proposed model compared to a synthesis baseline.

The duo defeated the American pair of Monica Seles and Jan-Michael Gambill in the finals. Federer later said that his experience with Hingis \"definitely helped me to become the player I am today.\"\n\nFederer's first singles win was at the 2001 Milan Indoor tournament, where he defeated Julien Boutter in the final. Although he won his first title already in 1999 on the Challenger tour, winning the doubles event in Segovia, Spain with Dutchman Sander Groen, the final was played on Federer's 18th birthday. In 2001, Federer made his first Grand Slam quarterfinal at the French Open, losing to former world No. 2 and eventual finalist Àlex Corretja. His run to the French quarterfinals launched him into the top 15 for the first time in his career.\n\nHis international breakthrough came at the 2001 Wimbledon Championships, when the 19-year-old Federer faced the four-time defending champion and all-time Grand Slam leader Pete Sampras. Federer beat the No. 1 seed in a five-set match to reach the quarterfinals. In the quarters he faced Englishman Tim Henman, eventually losing in a fourth-set tiebreaker.\n\nThe first final he reached at the Masters level came at the 2002 Miami Masters event, where he lost to former and future No. 1 Andre Agassi on hard court. Federer won his first Master Series event at the 2002 Hamburg Masters on clay, over Marat Safin; the victory put him in the top 10 for the first time. Federer made 10 singles finals between 1998 and 2002, of which he won four and lost six. He also made six finals in doubles. He finished 2001 with an ATP ranking of No. 13, and 2002 was the first year he was ranked within the top 10, finishing at No. 6.\n\n2003: Grand Slam breakthrough at Wimbledon\nMain article: 2003 Roger Federer tennis season\nIn 2003, Federer won his first Grand Slam singles title at Wimbledon, beating Andy Roddick in the semifinals and Mark Philippoussis in the final. In August he had a chance to take over the No. 1 ranking for the first time from Andre Agassi if he made it to the Montreal final. However, he fell in the semifinals to Roddick, in a final-set tiebreaker, leaving him 120 points behind Agassi. This, coupled with early losses to David Nalbandian at Cincinnati and the US Open, denied Federer the chance to become No. 1 for the duration of the season.\n\nFederer won his first and only doubles Masters event in Miami with Max Mirnyi and made it to one singles Masters event in Rome on clay, which he lost. Federer made it to nine finals on the ATP Tour and won seven of them, including the 500 series events at Dubai and Vienna. Lastly, Federer won the year-end championships over Andre Agassi, finishing the year as world No. 2, narrowly behind Andy Roddick by only 160 points.\n\n2004: Imposing dominance\nMain article: 2004 Roger Federer tennis season\nDuring 2004 Federer won three Grand Slam singles titles and became the first person to do in one season so since Mats Wilander in 1988. His first major hard-court title came at the Australian Open over Marat Safin, making him the world No. 1 for the first time. He then won his second Wimbledon crown over Andy Roddick. At the US Open, Federer defeated the 2001 champion, Lleyton Hewitt, for his first title there.\n\nFederer won three ATP Masters events, one on clay in Hamburg, and the other two on hard surfaces at Indian Wells and in Canada. Federer took the ATP 500 series event at Dubai and wrapped up the year by winning the year-end championships for the second time. He also won his first tournament on home soil by capturing the Swiss Open in Gstaad. His 11 singles titles were the most of any player in two decades, and his record of 74–6 was the best since Ivan Lendl in 1986. He reached the year-end No. 1 ranking for the first time.\n\n2005: Consolidating dominance\nMain article: 2005 Roger Federer tennis season\nIn 2005, Federer failed to reach the finals of the first two Grand Slam tournaments, losing the Australian Open semifinal to eventual champion Safin after holding match points, and the French Open semifinal to eventual champion Rafael Nadal. However, Federer reestablished his dominance on grass, winning Wimbledon for a third time by defeating Andy Roddick. At the US Open, Federer defeated Andre Agassi in the latter's last major final.\n\nFederer also took four Masters wins: Indian Wells, Miami and Cincinnati on hard court, and Hamburg on clay. The win in Miami was particularly noteworthy as it was the first final contested between Federer and Nadal. Federer recovered from two sets and a break down to take the final in five sets. Furthermore, Federer won two ATP 500 series events at Rotterdam and Dubai. Federer lost the year-end championships to David Nalbandian in five sets while playing through a foot injury that sidelined him for almost the rest of the season after September. He maintained his position as No. 1 for the entire season.\n\nFederer won 11 singles titles, which ties his 2004 season. Federer's 81 match victories were the most since Pete Sampras in 1993, and his record of 81–4 (95.2%) remains the third-best winning percentage in the Open Era behind John McEnroe's 1984 and Jimmy Connors's 1974.\n\n2006: Career-best season\nMain article: 2006 Roger Federer tennis season\nThe 2006 season was statistically the best season of Federer's career. In November 2011, Stephen Tignor, chief editorial writer for Tennis.com, ranked Federer's 2006 season as statistically the second-best season of all time during the Open Era, behind Rod Laver's Grand Slam year of 1969.\n\n\nFederer hits a forehand at the 2006 US Open, where he became the first man in history to achieve the Wimbledon-US Open double for three consecutive seasons.\nFederer won 12 singles titles (the most of any player since Thomas Muster in 1995 and John McEnroe in 1984) and had a match record of 92–5 (the most wins since Ivan Lendl in 1982). Federer reached the finals in an astounding 16 of the 17 tournaments he entered during the season.\n\nIn 2006, Federer won three Grand Slam singles titles and reached the final of the other, with the only loss coming against Nadal in the French Open. This was Federer and Nadal's first meeting in a Grand Slam final. He was the first man to reach all four finals in a calendar year since Rod Laver in 1969. Federer defeated Nadal in the Wimbledon Championships final. In the Australian Open, Federer defeated Marcos Baghdatis, and at the US Open, Federer defeated 2003 champion Roddick. In addition, Federer reached six Masters finals, winning four on hard surfaces and losing two on clay to Nadal. Federer, however, consistently pushed Nadal to the limit on clay throughout the season taking him to fourth-set tiebreakers in Monte-Carlo and Paris, and a thrilling match in Rome that went to a deciding fifth-set tiebreaker.\n\nFederer won one ATP 500 series event in Tokyo and captured the year-end championships for the third time in his career, again finishing the year as world No. 1. Federer only lost to two players during 2006, to Nadal four times in finals, and to 19-year-old Andy Murray in the second round of the 2006 Cincinnati Masters, in what was Federer's only defeat before the final of a tournament that year. Federer finished the season on a 29-match winning streak, as well as winning 48 of his last 49 matches after the French Open.\n\nNear the end of the season he won his hometown tournament, the Swiss Indoors in Basel, Switzerland for the first time, having finished runner up in 2000 and 2001, and missing the tournament in 2004 and 2005 due to injuries.\n\n2007: Holding off young rivals\nMain article: 2007 Roger Federer tennis season\nIn 2007, Federer reached all four Grand Slam singles finals, winning three of them again. He won the Australian Open without dropping a set, beating Fernando González in the final. This made him the first man in the 21st century to accomplish the feat, as Björn Borg at the 1980 French Open was the last to win a Grand Slam tournament without the loss of a set. Federer had entered the year on a huge winning streak and after capturing his fourth Dubai crown Federer's winning streak stood at 41 matches, the longest of his career and only five shy of the record. Federer entered Indian Wells as the three-time defending champion, but his streak ended in controversy. He was defeated by an Argentine, Guillermo Cañas, who had failed a drug test for illegal doping.\n\n\nFederer was called \"Darth Federer\" by fans and commentators at the 2007 US Open.\nThis surprising first-round loss marked the first time he was defeated since August 2006, a period spanning over 7 months.\n\nDuring the clay season Federer's victory in the Hamburg Masters final was particularly impressive, as it snapped Nadal's 81-match winning streak on clay, an Open-era record. Federer turned the match around from a set down to sweep 12 of the final 14 games, including a final set bagel. At the French Open, some anticipated that Federer could become the first man in almost 40 years to hold all four majors simultaneously, having just resoundingly defeated young rival Nadal on clay entering the tournament. However, in a repeat of the previous year Federer played a tough four-set final against Nadal, but was undone by going 1/17 on break-point chances.\n\nAt Wimbledon Federer entered the tournament not only as the four-time defending champion, but also riding a 48-match winning streak on grass. Once again, he defeated Rafael Nadal for a second consecutive year in the final, this time in a thrilling five-set encounter that many analysts hailed as the greatest Wimbledon final since 1980. Victory at Wimbledon equaled him with Björn Borg for the record of five consecutive championships at the All England Club.\n\nFederer reached the final in Montreal before playing a young and relatively unknown Serbian named Novak Djokovic. Djokovic proved his potential by beating the world No. 1 in a final-set tiebreaker upset. Federer rebounded in Cincinnati to capture his fifth title of the year. Federer entered the US Open as the three-time defending champion and faced Djokovic in the final. This time, Federer prevailed in a close straight-set match. Victory in New York moved him ahead of Laver and Borg for third on the all-time list of major championship victories. Throughout the tournament the American press nicknamed him Darth Federer for his all-black attire (which included tuxedo-striped shorts) and the tournament played \"The Imperial March\" from Star Wars when he was announced onto the court for each of his matches. He closed out the year with victories in Basel and the year-end championships in Shanghai.\n\nHe finished the season as the year-end No. 1 for the fourth year in a row, demonstrating his dominance, and during these four years he won 11 Grand Slam singles titles. After his phenomenal triple Grand Slam season yet again, Federer became the only player in history to win three majors in a year for three years (2004, 2006, 2007). It was the third consecutive season that Federer held the No. 1 ranking for all 52 weeks of the year.\n\n2008: Illness, Olympic Gold, and fifth US Open\nMain article: 2008 Roger Federer tennis season\nFederer's success in 2008 was severely hampered by a lingering bout of mononucleosis, which he suffered during the first half of the year. At the end of the year he suffered a back injury.\n\nIn 2008, Federer captured one Grand Slam, a singles title at the US Open over Andy Murray. Federer was defeated by Nadal in two Grand Slam finals, the French Open and Wimbledon, which was regarded as the best match of tennis history by many, when he was going for six straight wins to break Björn Borg's record. He came back from two sets down to force a fifth set, where he fell just two points from the title. At the Australian Open Federer lost in the semifinals to eventual winner Djokovic, which ended his record of 10 consecutive finals. He lost twice in Masters finals on clay to Nadal, at Monte Carlo and Hamburg. Federer captured three titles playing in 250-level events at Estoril, Halle, and Basel.\n\nAt the Olympic Games Federer and Stan Wawrinka won the gold medal in doubles, after beating the Bryan brothers American team in the semifinals and the Swedish duo of Simon Aspelin and Thomas Johansson in the final. However, Federer could reach only the quarterfinals in the singles draw, bowing out to then No. 8 James Blake, ceding his No. 1 ranking to Nadal after being at the top for a record 237 consecutive weeks. He ended the year ranked No. 2.\n\nFederer entered the 2009 season with 13 Grand Slams, only one behind Pete Sampras' all-time record. The season began with a loss to Nadal in the final of the Australian Open in a hotly contested five-set match. Federer struggled following the defeat in Melbourne and entered the clay season without a title.\n\n\nFederer winning the 2009 French Open, and completing the career Grand Slam\nFederer's season turned around in the final Masters event of the clay season when he defeated Nadal on clay for only the second time to capture the Madrid Masters. Federer entered the French Open with few predicting him to win the elusive Parisian title having lost to Nadal in the final weekend for the past four seasons. After Nadal's unexpected defeat to Robin Söderling, Federer became the overwhelming favorite. In his next match, he came from two sets and break point down in the third set to defeat Tommy Haas in five sets. He also fought back from a two-sets-to-one deficit against a young Juan Martín del Potro to win a five setter in the semifinals. In the final, he faced Söderling, and with straight sets victory, he finally captured the Coupe des Mousquetaires and career Grand Slam. This victory also tied him with Pete Sampras for the most Grand Slam singles titles.\n\nFederer turned his sights to the grass courts of Wimbledon, where he breezed his way up to the final. In the championship match he faced long-time rival Andy Roddick in what was their eighth and final meeting at a Grand Slam. Roddick pushed Federer into a record-setting fifth set, which Federer claimed 16–14 to win his 15th Grand Slam singles title, breaking the all-time record of Pete Sampras.\n\nFederer continued his summer run by winning his third title on the lightning-fast courts of the Cincinnati Masters, defeating Novak Djokovic in the final. At the US Open he defeated Söderling in the quarters and Djokovic, for the third consecutive year, in the semifinals. On the penultimate point of the Djokovic match he hit what many consider to be the greatest shot of his career, a tweener winner, to set up match points. Federer was defeated by del Potro in the final despite leading two sets to one and falling just two points from the title in the fourth set.\n\nThe 2009 season was perhaps the most historically relevant of Federer's career as he completed a career Grand Slam by winning his first French Open title and won a men's record fifteenth Grand Slam singles title at Wimbledon, surpassing Pete Sampras's mark of fourteen. The Wimbledon final was also historic for being the longest Grand Slam final in terms of games played with Federer prevailing 16–14 in the fifth set.\n\nFederer finished the season as the year-end No. 1 for the fifth time in his career.\n\n2010: Fourth Australian Open\nMain article: 2010 Roger Federer tennis season\n\nFederer won a record 16th major at the 2010 Australian Open.\nFederer started the year with a win at the Australian Open, where he defeated Andy Murray in the final, extending the Grand Slam singles record to sixteen titles and matching Andre Agassi's record of four Australian Open titles. Since Wimbledon 2005 Federer had made 18 out of 19 finals in Grand Slam tournaments, a period of sustained excellence unparalleled in the Open Era. This tournament, however, marked the end of his dominance at the majors.\n\nAt the French Open, Federer won his 700th tour match and 150th tour match on clay. However, he failed to reach a Grand Slam semifinal for the first time since the 2004 French Open, losing to Söderling in the last 8 and relinquishing his No. 1 ranking, having been just one week away from equaling Pete Sampras's record of 286 weeks as world No. 1. In a huge upset at Wimbledon, Federer lost in the last 8 again to Tomáš Berdych and fell to No. 3 in the rankings for the first time in 6 years and 8 months.\n\nTowards the middle of July, Federer hired Pete Sampras' old coach Paul Annacone on a trial basis to put his tennis game and career back on track. At the 2010 US Open Federer reached the semifinals, where he lost a five-set match to Novak Djokovic after holding two match points. Federer made it to four Masters finals prevailing against Mardy Fish at the Cincinnati Masters.\n\nFederer finished the year in strong form, winning indoor titles at the Stockholm Open, Swiss Indoors, and the ATP Finals in London bringing his tally to 66 career titles. Federer won the year-end championships in London by beating rival Rafael Nadal for his fifth title at the event. He beat all contenders except Nadal in straight sets. It remains the only tournament in his career where Federer defeated all fellow members of the Big Four. In 2010 Federer finished in the top two for the eighth consecutive season.\n\n2011: Tour Finals title record\nMain article: 2011 Roger Federer tennis season\nThe year 2011 was a lean year for Federer, although great by most player's standards. He was defeated in straight sets in the semifinals of the 2011 Australian Open by eventual champion Novak Djokovic, marking the first time since July 2003 that he did not hold any of the four major titles. In the French Open semifinals, Federer ended Djokovic's undefeated streak of 43 consecutive wins with a four-set victory. Federer then lost in the final to Rafael Nadal. At Wimbledon Federer advanced to his 29th consecutive Grand Slam quarterfinal, losing to Jo-Wilfried Tsonga. It marked the first time in his career that he had lost a Grand Slam tournament match after winning the first two sets.\n\nAt the US Open Federer lost in the semifinals to Novak Djokovic in five sets. In a repeat of previous year's semifinal event, Federer again squandered two match points on his own serve before losing after winning first two sets for second consecutive time in the year. The loss meant that it was the first time since 2002 that Federer had not won any of the four grand slam titles.\n\nIn September 2011, in a South African poll, Federer was voted the second most trusted and respected person in the world next to Nelson Mandela.\n\nFederer finished the season successfully in the indoor season, winning his last three tournaments of the year at the Swiss Indoors, Paris Masters, and ATP Finals, forming a 16 match winning streak. Federer finished the year ranked No. 3.",
        "answer": "2009 was arguably the most important of his career since he won his first and only French Open title, completing the career grand slam. He was also able to surpass Pete Sampras' record of fourteen men's grand slam titles.\n\nUntil then, Federer had won the three other grand slams - Wimbledon, Australian Open and US Open but the French Open was elusive as he had to repeatedly compete on the clay court of Rolland Garros against Rafael Nadal, who was a clay court expert and he lost to him on multiple occasions.\n\n2004 was also an important year in Federer's career because he established dominance in the sport by winning three out of the four grand slams of the year and ending the year as the world number one for the first time in his long career.",

        "answer": "No.",
        "evidence": "In the present work, we address these limitations by providing a more nuanced evaluation of the learning capabilities of RNNs. In particular, we investigate the effects of three different aspects of a network's generalization: data distribution, length-window, and network capacity. We define an informative protocol for assessing the performance of RNNs: Instead of training a single network until it has learned its training set and then evaluating it on its test set, as BIBREF9 do in their study, we monitor and test the network's performance at each epoch during the entire course of training. This approach allows us to study the stability of the solutions reached by the network. Furthermore, we do not restrict ourselves to a test set of sequences of fixed lengths during testing. Rather, we exhaustively enumerate all the sequences in a language by their lengths and then go through the sequences in the test set one by one until our network errs $k$ times, thereby providing a more fine-grained evaluation criterion of its generalization capabilities.\nPrevious studies have examined various length distribution models to generate appropriate training sets for each formal language: BIBREF16 , BIBREF11 , BIBREF12 , for instance, used length distributions that were skewed towards having more short sequences than long sequences given a training length-window, whereas BIBREF9 used a uniform distribution scheme to generate their training sets. The latter briefly comment that the distribution of lengths of sequences in the training set does influence the generalization ability and convergence speed of neural networks, and mention that training sets containing abundant numbers of both short and long sequences are learned by networks much more quickly than uniformly distributed regimes. Nevertheless, they do not systematically compare or explicitly report their findings. To study the effect of various length distributions on the learning capability and speed of LSTM models, we experimented with four discrete probability distributions supported on bounded intervals (Figure 2 ) to sample the lengths of sequences for the languages. We briefly recall the probability distribution functions for discrete uniform and Beta-Binomial distributions used in our data generation procedure.\nFurthermore, we do not restrict ourselves to a test set of sequences of fixed lengths during testing.

        "answer": "The developers of an ontology are usually those who have intimate knowledge about entities described in the ontology and often have some sort of comments about classes, objects, and instances of the ontology.",
        "evidence": "Natural language generation (NLG) has been one of the key topics of research in natural language processing, which was highlighted by the huge body of work on NLG surveyed in BIBREF0, BIBREF1. With the advances of several devices capable of understanding spoken language and conducting conversation with human (e.g., Google Home, Amazon Echo) and the shrinking gap created by the digital devices, it is not difficult to foresee that the market and application areas of NLG systems will continue to grow, especially in applications whose users are non-experts. In such application, a user often asks for certain information and waits for the answer and a NLG module would return the answer in spoken language instead of text such as in question-answering systems or recommendation systems. The NLG system in these two applications uses templates to generate the answers in natural language for the users. A more advanced NLG system in this direction is described in BIBREF2, which works with ontologies annotated using the Attempto language and can generate a natural language description for workflows created by the systems built in the Phylotastic project. The applications targeted by these systems are significantly different from NLG systems, whose main purpose is to generate high-quality natural language description of objects or reports, such as those reported in the recent AAAI conference BIBREF3, BIBREF4, BIBREF5.\nThe present paper is motivated by the need to generate natural language description of computational results to non-expert users such as those developed in the Phylotastic project. In this project, the users are experts in evolutionary biology but are none experts in ontologies and web services. When a user places a request, he/she will receive a workflow consisting of web services, whose inputs and outputs are specified by instances of classes in the ontologies working with web services, as well as the ordering and relationships between the services. To assist the user in understanding the workflow, a natural language description of the workflow is generated. In order to accomplish the task, the NLG system in the Phylotastic project proposes to annotate elements of the ontologies using Attempto, a simple subset of English with precisely defined syntax and semantics.\nIn this paper, we propose a system that addresses the limitation of the system discussed in the Phylotastic project BIBREF2. Specifically, we assume that the annotations given in an ontology are natural language sentences. This is a reasonable assumption given that the developers of an ontology are usually those who have intimate knowledge about entities described in the ontology and often have some sort of comments about classes, objects, and instances of the ontology. We then show that the system is very flexible and can be used for the same purpose with new ontologies.\nThe rest of the paper is organized as follows. Section SECREF2 briefly reviews the basics of Grammatical Framework (GF)BIBREF6. Section SECREF3 describes the main modules of the system. Section SECREF4 includes two use cases of the system using an available ontologies against in the context of reasoning about ontologies. Specifically, it compares with the system used in the Phylotastic project and an ontology about people. This section also contains a use case that highlights the versatility of the proposed system by addressing a challenge to create an abstract Wikipedia BIBREF7. Related works are discussed in Section SECREF5. Section SECREF6 concludes the paper.\nThis is a reasonable assumption given that the developers of an ontology are usually those who have intimate knowledge about entities described in the ontology and often have some sort of comments about classes, objects, and instances of the ontology.",

The arguments in the comments and the commenters (the users who leave the comments) provide hints on the post's content and further facilitate stance classification.\nIn this paper, we propose the user-topic-comment neural network (UTCNN), a deep learning model that utilizes user, topic, and comment information. We attempt to learn user and topic representations which encode user interactions and topic influences to further enhance text classification, and we also incorporate comment information. We evaluate this model on a post stance classification task on forum-style social media platforms. The contributions of this paper are as follows: 1. We propose UTCNN, a neural network for text in modern social media channels as well as legacy social media, forums, and message boards — anywhere that reveals users, their tastes, as well as their replies to posts. 2. When classifying social media post stances, we leverage users, including authors and likers. User embeddings can be generated even for users who have never posted anything. 3. We incorporate a topic model to automatically assign topics to each post in a single topic dataset. 4. We show that overall, the proposed method achieves the highest performance in all instances, and that all of the information extracted, whether users, topics, or comments, still has its contributions.\nIn this paper, we propose the user-topic-comment neural network (UTCNN), a deep learning model that utilizes user, topic, and comment information.",

        "answer": "Yes, it could.",
        "evidence": "* Equal contribution. Listing order is random.\nLemmatization is a core NLP task that involves a string-to-string transduction from an inflected word form to its citation form, known as the lemma. More concretely, consider the English sentence: The bulls are running in Pamplona. A lemmatizer will seek to map each word to a form you may find in a dictionary—for instance, mapping running to run. This linguistic normalization is important in several downstream NLP applications, especially for highly inflected languages. Lemmatization has previously been shown to improve recall for information retrieval BIBREF0 , BIBREF1 , to aid machine translation BIBREF2 , BIBREF3 and is a core part of modern parsing systems BIBREF4 , BIBREF5 .\nHowever, the task is quite nuanced as the proper choice of the lemma is context dependent. For instance, in the sentence A running of the bulls took place in Pamplona, the word running is its own lemma, since, here, running is a noun rather than an inflected verb. Several counter-examples exist to this trend, as discussed in depth in haspelmath2013understanding. Thus, a good lemmatizer must make use of some representation of each word's sentential context. The research question in this work is, then, how do we design a lemmatization model that best extracts the morpho-syntax from the sentential context?\nRecent work BIBREF7 has presented a system that directly summarizes the sentential context using a recurrent neural network to decide how to lemmatize. As N18-1126's system currently achieves state-of-the-art results, it must implicitly learn a contextual representation that encodes the necessary morpho-syntax, as such knowledge is requisite for the task. We contend, however, that rather than expecting the network to implicitly learn some notion of morpho-syntax, it is better to explicitly train a joint model to morphologically disambiguate and lemmatize. Indeed, to this end, we introduce a joint model for the introduction of morphology into a neural lemmatizer. A key feature of our model is its simplicity: Our contribution is to show how to stitch existing models together into a joint model, explaining how to train and decode the model. However, despite the model's simplicity, it still achieves a significant improvement over the state of the art on our target task: lemmatization.\nExperimentally, our contributions are threefold. First, we show that our joint model achieves state-of-the-art results, outperforming (on average) all competing approaches on a 20-language subset of the Universal Dependencies (UD) corpora BIBREF8 . Second, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization. Finally, we provide a detailed error analysis indicating when and why morphological analysis helps lemmatization. We offer two tangible recommendations: one is better off using a joint model (i) for languages with fewer training data available and (ii) languages that have richer morphology.\nOur system and pre-trained models on all languages in the latest version of the UD corpora are released at https://sigmorphon.github.io/sharedtasks/2019/task2/.\nSecond, by providing the joint model with gold morphological tags, we demonstrate that we are far from achieving the upper bound on performance—improvements on morphological tagging could lead to substantially better lemmatization.",

Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes.\n\nThe Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is 94,250 square miles (244,106 km2), and the total volume (measured at the low water datum) is 5,439 cubic miles (22,671 km3), slightly less than the volume of Lake Baikal (5,666 cu mi or 23,615 km3, 22–23% of the world's surface fresh water). Because of their sea-like characteristics, such as rolling waves, sustained winds, strong currents, great depths, and distant horizons, the five Great Lakes have long been called inland seas. Depending on how it is measured, by surface area, either Lake Superior or Lake Michigan-Huron is the second-largest lake in the world and the largest freshwater lake. Lake Michigan is the largest lake that is entirely within one country.\n\nThe Great Lakes began to form at the end of the Last Glacial Period around 14,000 years ago, as retreating ice sheets exposed the basins they had carved into the land, which then filled with meltwater.

I have been considering getting a pet for companionship, but after reviewing my rental contract, I noticed the only permitted animals are small dogs and animals that can be kept in a tank, like hamsters and fish.\n\nI am hoping you would reconsider these restrictions and allow me to have a cat. I am more than willing to resign a rental contract to include the requisite pet deposit and pet rent.\n\nI thought about a dog, since those animals are already in the contract, but I don't want a dog. Since I work long hours, it's not ideal to have a dog in my unit. My unit is small and could be claustrophobic for a dog who has a lot of energy. I also don't want to leave a dog alone because it may bark and disturb the other tenants in the building. Dogs also urinate and defecate in the shared yard around the property, which is gross, considering not everyone picks up after their dogs. Also, I am allergic to dogs, so this rules out dogs.\n\nI also considered a hamster or fish, but I am reluctant to have either of those, as well. Firstly, they do not offer the same cuddly companionship of a cat. If a hamster got loose, it could cause far more damage to a unit than a cat could -- the hamster could defecate in many areas, chew electrical wires, and chew through drywall. Fish pose a problem if the tank cracks or breaks, which would cause lots of water damage to the flooring.\n\nI recognize there are drawbacks to any pet, including cats, and I understand that some landlords are reluctant to permit cats, because there is an impression that cats may be more destructive, such as peeing in inappropriate places. However, I believe a cat is the least-destructive option of all. As my unit is not carpeted, I don't believe persistent urination stains will be an issue. Cats are easy to litter box train and I plan to put the litter box in the tiled bathroom where there is no opportunity for urine to get into the subfloor. Cats are less destructive than dogs, because they don't chew on things like furniture and doorways. Cats also are not nearly as loud as barking dogs. \n\nI have already looked into pets at the local animal shelter and found a possible new roommate, who is a friendly two-year-old cat and is housebroken and box-trained. This is an ideal pet, since I don't have to risk accidents with box-training a kitten, and it's unlikely the cat will be destructive if it's already housebroken.\n\nI believe a cat would be the ideal companion for me, given my work schedule and my preference for my ideal pet. I am happy to discuss my desire in person and further elaborate my plan on how I will continue to maintain a clean and tidy unit with a cat, such as purchasing an automatic robot vacuum and mop to ensure an extra clean space.\n\nPlease consider my request. I look forward to your response. \n\nSincerely,\nSteve",

But while other NLP tasks have been extensively investigated, sarcasm detection is a relatively new research topic which has gained increasing interest only recently, partly thanks to the rise of social media analytics and sentiment analysis. Sentiment analysis BIBREF16 and using multimodal information as a new trend BIBREF17 , BIBREF18 , BIBREF19 , BIBREF20 , BIBREF14 is a popular branch of NLP research that aims to understand sentiment of documents automatically using combination of various machine learning approaches BIBREF21 , BIBREF22 , BIBREF20 , BIBREF23 .\nAn early work in this field was done by BIBREF6 on a dataset of 6,600 manually annotated Amazon reviews using a kNN-classifier over punctuation-based and pattern-based features, i.e., ordered sequence of high frequency words. BIBREF1 used support vector machine (SVM) and logistic regression over a feature set of unigrams, dictionary-based lexical features and pragmatic features (e.g., emoticons) and compared the performance of the classifier with that of humans. BIBREF24 described a set of textual features for recognizing irony at a linguistic level, especially in short texts created via Twitter, and constructed a new model that was assessed along two dimensions: representativeness and relevance. BIBREF5 used the presence of a positive sentiment in close proximity of a negative situation phrase as a feature for sarcasm detection. BIBREF25 used the Balanced Window algorithm for classifying Dutch tweets as sarcastic vs. non-sarcastic; n-grams (uni, bi and tri) and intensifiers were used as features for classification.\n BIBREF26 compared the performance of different classifiers on the Amazon review dataset using the imbalance between the sentiment expressed by the review and the user-given star rating. Features based on frequency (gap between rare and common words), written spoken gap (in terms of difference between usage), synonyms (based on the difference in frequency of synonyms) and ambiguity (number of words with many synonyms) were used by BIBREF3 for sarcasm detection in tweets. BIBREF9 proposed the use of implicit incongruity and explicit incongruity based features along with lexical and pragmatic features, such as emoticons and punctuation marks. Their method is very much similar to the method proposed by BIBREF5 except BIBREF9 used explicit incongruity features. Their method outperforms the approach by BIBREF5 on two datasets.\n BIBREF8 compared the performance with different language-independent features and pre-processing techniques for classifying text as sarcastic and non-sarcastic. The comparison was done over three Twitter dataset in two different languages, two of these in English with a balanced and an imbalanced distribution and the third one in Czech. The feature set included n-grams, word-shape patterns, pointedness and punctuation-based features.\nIn this work, we use features extracted from a deep CNN for sarcasm detection. Some of the key differences between the proposed approach and existing methods include the use of a relatively smaller feature set, automatic feature extraction, the use of deep networks, and the adoption of pre-trained NLP models.\nIn this work, we use features extracted from a deep CNN for sarcasm detection.",

        "evidence": "Task-oriented dialog systems have become ubiquitous, providing a means for billions of people to interact with computers using natural language. Moreover, the recent influx of platforms and tools such as Google's DialogFlow or Amazon's Lex for building and deploying such systems makes them even more accessible to various industries and demographics across the globe.\nTools for developing such systems start by guiding developers to collect training data for intent classification: the task of identifying which of a fixed set of actions the user wishes to take based on their query. Relatively few public datasets exist for evaluating performance on this task, and those that do exist typically cover only a very small number of intents (e.g. BIBREF0, which has 7 intents). Furthermore, such resources do not facilitate analysis of out-of-scope queries: queries that users may reasonably make, but fall outside of the scope of the system-supported intents.\nFigure FIGREF1 shows example query-response exchanges between a user and a task-driven dialog system for personal finance. In the first user-system exchange, the system correctly identifies the user's intent as an in-scope balance query. In the second and third exchanges, the user queries with out-of-scope inputs. In the second exchange, the system incorrectly identifies the query as in-scope and yields an unrelated response. In the third exchange, the system correctly classifies the user's query as out-of-scope, and yields a fallback response.\nOut-of-scope queries are inevitable for a task-oriented dialog system, as most users will not be fully cognizant of the system's capabilities, which are limited by the fixed number of intent classes. Correctly identifying out-of-scope cases is thus crucial in deployed systems—both to avoid performing the wrong action and also to identify potential future directions for development. However, this problem has seen little attention in analyses and evaluations of intent classification systems.\nThis paper fills this gap by analyzing intent classification performance with a focus on out-of-scope handling. To do so, we constructed a new dataset with 23,700 queries that are short and unstructured, in the same style made by real users of task-oriented systems. The queries cover 150 intents, plus out-of-scope queries that do not fall within any of the 150 in-scope intents.\nWe evaluate a range of benchmark classifiers and out-of-scope handling methods on our dataset. BERT BIBREF1 yields the best in-scope accuracy, scoring 96% or above even when we limit the training data or introduce class imbalance. However, all methods struggle with identifying out-of-scope queries. Even when a large number of out-of-scope examples are provided for training, there is a major performance gap, with the best system scoring 66% out-of-scope recall.

The insurance transaction involves the policyholder assuming a guaranteed, known, and relatively small loss in the form of a payment to the insurer (a premium) in exchange for the insurer's promise to compensate the insured in the event of a covered loss.

        "answer": "128.",
        "evidence": "We now evaluate LiLi in terms of its predictive performance and strategy formulation abilities.\nData: We use two standard datasets (see Table 4): (1) Freebase FB15k, and (2) WordNet INLINEFORM0 . Using each dataset, we build a fairly large graph and use it as the original KB ( INLINEFORM1 ) for evaluation. We also augment INLINEFORM2 with inverse triples ( INLINEFORM3 , INLINEFORM4 , INLINEFORM5 ) for each ( INLINEFORM6 , INLINEFORM7 , INLINEFORM8 ) following existing KBC methods.\nParameter Settings. Unless specified, the empirically set parameters (see Table 1) of LiLi are: INLINEFORM0 , INLINEFORM1 , INLINEFORM2 , INLINEFORM3 , INLINEFORM4 , INLINEFORM5 , INLINEFORM6 , INLINEFORM7 , INLINEFORM8 , INLINEFORM9 , INLINEFORM10 . For training RL-model with INLINEFORM11 -greedy strategy, we use INLINEFORM12 , INLINEFORM13 , pre-training steps=50000. We used Keras deep learning library to implement and train the prediction model. We set batch-size as 128, max. training epoch as 150, dropout as 0.2, hidden units and embedding size as 300 and learning rate as 5e-3 which is reduced gradually on plateau with factor 0.5 and patience 5. Adam optimizer and early stopping were used in training. We also shuffle INLINEFORM14 in each epoch and adjust class weights inversely proportional to class frequencies in INLINEFORM15 .\nLabeled Dataset Generation and Simulated User Creation. We create a simulated user for each KB to evaluate LiLi. We create the labeled datasets, the simulated user’s knowledge base ( INLINEFORM0 ), and the base KB ( INLINEFORM1 ) from INLINEFORM2 . INLINEFORM3 used as the initial KB graph ( INLINEFORM4 ) of LiLi.\nWe followed BIBREF16 for labeled dataset generation. For Freebase, we found 86 relations with INLINEFORM0 triples and randomly selected 50 from various domains. We randomly shuffle the list of 50 relations, select 25% of them as unknown relations and consider the rest (75%) as known relations. For each known relation INLINEFORM1 , we randomly shuffle the list of distinct triples for INLINEFORM2 , choose 1000 triples and split them into 60% training, 10% validation and 20% test. Rest 10% along with the leftover (not included in the list of 1000) triples are added to INLINEFORM3 . For each unknown relation INLINEFORM4 , we remove all triples of INLINEFORM5 from INLINEFORM6 and add them to INLINEFORM7 . In this process, we also randomly choose 20% triples as test instances for unknown INLINEFORM8 which are excluded from INLINEFORM9 . Note that, now INLINEFORM10 has at least 10% of chosen triples for each INLINEFORM11 (known and unknown) and so, user is always able to provide clues for both cases. For each labeled dataset, we randomly choose 10% of the entities present in dataset triples, remove triples involving those entities from INLINEFORM12 and add to INLINEFORM13 . At this point, INLINEFORM14 gets reduced to INLINEFORM15 and is used as INLINEFORM16 for LiLi. The dataset stats in Table 4 shows that the base KB (60% triples of INLINEFORM17 ) is highly sparse (compared to original KB) which makes the inference task much harder. WordNet dataset being small, we select all 18 relations for evaluation and create labeled dataset, INLINEFORM18 and INLINEFORM19 following Freebase. Although the user may provide clues 100% of the time, it often cannot respond to MLQs and CLQs (due to lack of required triples/facts). Thus, we further enrich INLINEFORM20 with external KB triples.\nGiven a relation INLINEFORM0 and an observed triple ( INLINEFORM1 , INLINEFORM2 , INLINEFORM3 ) in training or testing, the pair ( INLINEFORM4 , INLINEFORM5 ) is regarded as a +ve instance for INLINEFORM6 . Following BIBREF18 , for each +ve instance ( INLINEFORM7 , INLINEFORM8 ), we generate two negative ones, one by randomly corrupting the source INLINEFORM9 , and the other by corrupting the target INLINEFORM10 . Note that, the test triples are not in INLINEFORM11 or INLINEFORM12 and none of the -ve instances overlap with the +ve ones.\nBaselines. As none of the existing KBC methods can solve the OKBC problem, we choose various versions of LiLi as baselines.\nSingle: Version of LiLi where we train a single prediction model INLINEFORM0 for all test relations.\nSep: We do not transfer (past learned) weights for initializing INLINEFORM0 , i.e., we disable LL.\nF-th): Here, we use a fixed prediction threshold 0.5 instead of relation-specific threshold INLINEFORM0 .\nBG: The missing or connecting links (when the user does not respond) are filled with “@-RelatedTo-@\" blindly, no guessing mechanism.\nw/o PTS: LiLi does not ask for additional clues via past task selection for skillset improvement.\nEvaluation Metrics. To evaluate the strategy formulation ability, we introduce a measure called Coverage( INLINEFORM0 ), defined as the fraction of total query data instances, for which LiLi has successfully formulated strategies that lead to winning. If LiLi wins on all episodes for a given dataset, INLINEFORM1 is 1.0. To evaluate the predictive performance, we use Avg. MCC and avg. +ve F1 score.\nWe used Keras deep learning library to implement and train the prediction model.

        "evidence": "The growing popularity of online interactions through social media has been shown to have both positive and negative impacts. While social media improves information sharing, it also facilitates the propagation of online harassment, including hate speech. These negative experiences can have a measurable negative impact on users. Recently, the Pew Research Center BIBREF0 reported that “roughly four-in-ten Americans have personally experienced online harassment, and 63% consider it a major problem.”\nTo address the growing problem of online hate, an extensive body of work has focused on developing automatic hate speech detection models and datasets BIBREF1, BIBREF2, BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF8. However, simply detecting and blocking hate speech or suspicious users often has limited ability to prevent these users from simply turning to other social media platforms to continue to engage in hate speech as can be seen in the large move of individuals blocked from Twitter to Gab BIBREF9. What's more, such a strategy is often at odds with the concept of free speech. As reported by the Pew Research Center BIBREF0, “Despite this broad concern over online harassment, 45% of Americans say it is more important to let people speak their minds freely online; a slightly larger share (53%) feels that it is more important for people to feel welcome and safe online.” The special rapporteurs representing the Office of the United Nations High Commissioner for Human Rights (OHCHR) have recommended that “The strategic response to hate speech is more speech.” BIBREF10 They encourage to change what people think instead of merely changing what they do, so they advocate more speech that educates about cultural differences, diversity, and minorities as a better strategy to counter hate speech.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task. Figure FIGREF5 illustrates the task. Our datasets consist of 5K conversations retrieved from Reddit and 12k conversations retrieved from Gab. Distinct from existing hate speech datasets, our datasets retain their conversational context and introduce human-written intervention responses. The conversational context and intervention responses are critical in order to build generative models to automatically mitigate the spread of these types of conversations.\nTo summarize, our contributions are three-fold:\nWe introduce the generative hate speech intervention task and provide two fully-labeled hate speech datasets with human-written intervention responses.\nOur data is collected in the form of conversations, providing better context.\nThe two data sources, Gab and Reddit, are not well studied for hate speech. Our datasets fill this gap.\nDue to our data collecting strategy, all the posts in our datasets are manually labeled as hate or non-hate speech by Mechanical Turk workers, so they can also be used for the hate speech detection task. The performance of commonly-used classifiers on our datasets is shown in Section SECREF6.\nTherefore, in order to encourage strategies of countering online hate speech, we propose a novel task of generative hate speech intervention and introduce two new datasets for this task.",

        "question": "What does the author use multiple prediction systems to do?",
        "answer": "Multiple prediction systems.",
        "evidence": "What would be possible if a person had an oracle that could immediately provide the answer to any question about the visual world? Sight-impaired users could quickly and reliably figure out the denomination of their currency and so whether they spent the appropriate amount for a product BIBREF0 . Hikers could immediately learn about their bug bites and whether to seek out emergency medical care. Pilots could learn how many birds are in their path to decide whether to change course and so avoid costly, life-threatening collisions. These examples illustrate several of the interests from a visual question answering (VQA) system, including tackling problems that involve classification, detection, and counting. More generally, the goal for VQA is to have a single system that can accurately answer any natural language question about an image or video BIBREF1 , BIBREF2 , BIBREF3 .\nEntangled in the dream of a VQA system is an unavoidable issue that, when asking multiple people a visual question, sometimes they all agree on a single answer while other times they offer different answers (Figure FIGREF1 ). In fact, as we show in the paper, these two outcomes arise in approximately equal proportions in today's largest publicly-shared VQA benchmark that contains over 450,000 visual questions. Figure FIGREF1 illustrates that human disagreements arise for a variety of reasons including different descriptions of the same concept (e.g., “minor\" and “underage\"), different concepts (e.g., “ghost\" and “photoshop\"), and irrelevant responses (e.g., “no\").\nOur goal is to account for whether different people would agree on a single answer to a visual question to improve upon today's VQA systems. We propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.\nOur work is partially inspired by the goal to improve how to employ crowds as the computing power at run-time. Towards satisfying existing users, gaining new users, and supporting a wide range of applications, a crowd-powered VQA system should be low cost, have fast response times, and yield high quality answers. Today's status quo is to assume a fixed number of human responses per visual question and so a fixed cost, delay, and potential diversity of answers for every visual question BIBREF2 , BIBREF0 , BIBREF4 . We instead propose to dynamically solicit the number of human responses based on each visual question. In particular, we aim to accrue additional costs and delays from collecting extra answers only when extra responses are needed to discover all plausible answers. We show in our experiments that our system saves 19 40-hour work weeks and $1800 to answer 121,512 visual questions, compared to today's status quo approach BIBREF0 .\nOur work is also inspired by the goal to improve how to employ crowds to produce the information needed to train and evaluate automated methods. Specifically, researchers in fields as diverse as computer vision BIBREF2 , computational linguistics BIBREF1 , and machine learning BIBREF3 rely on large datasets to improve their VQA algorithms. These datasets include visual questions and human-supplied answers. Such data is critical for teaching machine learning algorithms how to answer questions by example. Such data is also critical for evaluating how well VQA algorithms perform. In general, “bigger\" data is better. Current methods to create these datasets assume a fixed number of human answers per visual question BIBREF2 , BIBREF4 , thereby either compromising on quality by not collecting all plausible answers or cost by collecting additional answers when they are redundant. We offer an economical way to spend a human budget to collect answers from crowd workers. In particular, we aim to actively allocate additional answers only to visual questions likely to have multiple answers.\nThe key contributions of our work are as follows:\nWe propose multiple prediction systems to automatically decide whether a visual question will lead to human agreement and demonstrate the value of these predictions for a new task of capturing the diversity of all plausible answers with less human effort.",

Unexpectedly, disabling some heads leads not to a drop in accuracy, as one would expect, but to an increase in performance. This is effect is different across tasks and datasets. While disabling some heads improves the results, disabling the others hurts the results. However, it is important to note that across all tasks and datasets, disabling some heads leads to an increase in performance. The gain from disabling a single head is different for different tasks, ranging from the minimum absolute gain of 0.1% for STS-B, to the maximum of 1.2% for MRPC (see fig:disableheadsall). In fact, for some tasks, such as MRPC and RTE, disabling a random head gives, on average, an increase in performance. Furthermore, disabling a whole layer, that is, all 12 heads in a given layer, also improves the results. fig:disablelayers shows the resulting model performance on the target GLUE tasks when different layers are disabled.

Deep learning architectures used in the literature include Recurrent Neural Networks (RNNs), Convolutional Neural Networks (CNNs), Transformers, and Graph Neural Networks (GNNs).

Considering both long-term dependencies and short-term trends in multivariate time series, LSTnet combines both CNNs and RNNS in a unified model. LogTrans brings the Transformer model to time series forecasting with causal convolution in its attention mechanism. Informer further proposes a sparse self-attention mechanism to reduce the time complexity and memory usage. StemGNN is a GNN based model that considers the intra-temporal and inter-series correlations simultaneously. Unlike these works, we aim to learn general representations for time series data that can not only be used for forecasting but also other tasks, such as classification. Besides, the proposed framework is compatible with various architectures as encoders.\nTime series forecasting aims to predict the future L y time stamps, with the last L x observations. We follow to train a linear model regularized with the L2 norm penalty to make predictions. The output has dimension L y in the univariate case and L y × F for the multivariate case, where F is the feature dimension.\nDatasets and Baselines.

As shown in Tabel 1 and Tabel 4, comparison in both univariate and multivariate settings indicates that InfoTS consistently matches or outperforms the leading baselines. Some results of StemGNN are unavailable due to the out-of-memory issue. Specifically, we have the following observations. TS2Vec, another contrastive learning method with data augmentations, achieves the second-best performance in most cases. The consistent improvement of TS2Vec  over other baselines indicates the effectiveness of contrastive learning for time series representations learning. However, such universal data augmentations may not be the most informative ones to generate positive pairs. Comparing to TS2Vec, InfoTS decreases the average MSE by 11.4%, and the average MAE by 8.6% in the univariate setting. In the multivariate setting, the MSE and MAE decrease by 4.6% and 2.3%, respectively. The reason is that InfoTS can adaptively select the most suitable augmentations in a data-driven manner with high variety and high fidelity. Encoders trained with such informative augmentations learn representations with higher quality.\nSpecifically, we have the following observations.

        "question": "Although the paper argues the model is inspired by Siamese networks, it is indeed just using a shared GNN to encode both target and query graphs. In the field of combinatorial optimization, encoding graphs using GNN is straightforward. Perhaps the paper is not novel enough?",
        "answer": "A siamese network, by definition, means a neural network that contains one or more identical sub-networks. This is indeed the case in our architecture, where the sub-networks are GNNs. In our work, we do not claim to be the first to use siamese GNNs. However, shared weights due to siamese architecture lies at the core of our ability to preserve theoretical distance properties of the original graph space in the embedded space. We have emphasized this aspect in the updated version (see the discussion following Theorem 2 in Sec 3.2).",
        "evidence": "Fig. presents the architecture of NEUROSED. The input to our learning framework is a pair of graphs G Q (query), G T (target) along with the supervision data SED(G Q , G T ). Our objective is to train a model that can predict SED on unseen query and target graphs. The design of our model must be cognizant of the fact that computing SED is NP-hard and high quality training data is scarce. Thus, we use a Siamese architecture in which the weight sharing between the embedding models boosts learnability and generalization from low-volume data by imposing a strong prior that the same topological features must be extracted for both graphs.\nSiamese Networks: In these models, there are two networks with shared parameters applied to two inputs independently to compute representations. These representations are then passed through another module to compute a similarity score.\nSiamese Networks: In these models, there are two networks with shared parameters applied to two inputs independently to compute representations.****We note here that if different embedding models are used for G1 and G2, or if the distance computations are pair-dependent (Li et al., 2019), then Theorem 2 would not hold. It is easy to verify that the proof fails if EQ and ET are different embedding functions corresponding to the query and the target, or if E is a function of both G1 and G2.

The left blocks and the right blocks form two QANets, each of which takes a document and a question as the input and outputs an answer. In QANet, firstly, an embedding encoder obtains word and character embeddings for each word in INLINEFORM0 or INLINEFORM1 and then models the temporal interactions between words and refines word vectors to contextualized word representations. All encoder blocks used in QANet are composed exclusively of depth-wise separable convolutions and self-attention. The intuition here is that convolution components can model local interactions and self-attention components focus on modeling global interactions. The context-query attention layer generates the question-document similarity matrix and computes the question-aware vector representations of the context words. After that, a model encoder layer containing seven encoder blocks captures the interactions among the context words conditioned on the question. Finally, the output layer predicts a start position and an end position in the document to extract the answer span from the document.\nThe used architecture of the QA model is briefly summarized below.

The university played an important role in Edinburgh becoming a chief intellectual centre during the Scottish Enlightenment and contributed to the city being nicknamed the \"Athens of the North.\" Edinburgh is ranked among the top universities in the United Kingdom and the world.\n\nEdinburgh is a member of several associations of research-intensive universities, including the Coimbra Group, League of European Research Universities, Russell Group, Una Europa, and Universitas 21. In the fiscal year ending 31 July 2022, it had a total income of £1.262 billion, of which £331.6 million was from research grants and contracts. It has the third-largest endowment in the UK, behind only Cambridge and Oxford. The university has five main campuses in the city of Edinburgh, which include many buildings of historical and architectural significance such as those in the Old Town.\n\nEdinburgh is the seventh-largest university in the UK by enrolment and receives over 75,000 undergraduate applications per year, making it the second-most popular university in the UK by volume of applications. Edinburgh had the eighth-highest average UCAS points amongst British universities for new entrants in 2020. The university continues to have links to the royal family, having had Prince Philip, Duke of Edinburgh as its chancellor from 1953 to 2010 and Anne, Princess Royal since March 2011.\n\nThe alumni of the university includes some of the major figures of modern history.

        "evidence": "\nPeople are increasingly using social networking platforms such as Twitter, Facebook, YouTube, etc. to communicate their opinions and share information. Although the interactions among users on these platforms can lead to constructive conversations, they have been increasingly exploited for the propagation of abusive language and the organization of hate-based activities BIBREF0, BIBREF1, especially due to the mobility and anonymous environment of these online platforms. Violence attributed to online hate speech has increased worldwide. For example, in the UK, there has been a significant increase in hate speech towards the immigrant and Muslim communities following the UK's leaving the EU and the Manchester and London attacks. The US also has been a marked increase in hate speech and related crime following the Trump election. Therefore, governments and social network platforms confronting the trend must have tools to detect aggressive behavior in general, and hate speech in particular, as these forms of online aggression not only poison the social climate of the online communities that experience it, but can also provoke physical violence and serious harm BIBREF1.\nRecently, the problem of online abusive detection has attracted scientific attention. Proof of this is the creation of the third Workshop on Abusive Language Online or Kaggle’s Toxic Comment Classification Challenge that gathered 4,551 teams in 2018 to detect different types of toxicities (threats, obscenity, etc.). In the scope of this work, we mainly focus on the term hate speech as abusive content in social media, since it can be considered a broad umbrella term for numerous kinds of insulting user-generated content. Hate speech is commonly defined as any communication criticizing a person or a group based on some characteristics such as gender, sexual orientation, nationality, religion, race, etc. Hate speech detection is not a stable or simple target because misclassification of regular conversation as hate speech can severely affect users’ freedom of expression and reputation, while misclassification of hateful conversations as unproblematic would maintain the status of online communities as unsafe environments BIBREF2.\nTo detect online hate speech, a large number of scientific studies have been dedicated by using Natural Language Processing (NLP) in combination with Machine Learning (ML) and Deep Learning (DL) methods BIBREF3, BIBREF4, BIBREF5, BIBREF6, BIBREF7, BIBREF0. Although supervised machine learning-based approaches have used different text mining-based features such as surface features, sentiment analysis, lexical resources, linguistic features, knowledge-based features or user-based and platform-based metadata BIBREF8, BIBREF9, BIBREF10, they necessitate a well-defined feature extraction approach. The trend now seems to be changing direction, with deep learning models being used for both feature extraction and the training of classifiers. These newer models are applying deep learning approaches such as Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), etc.BIBREF6, BIBREF0 to enhance the performance of hate speech detection models, however, they still suffer from lack of labelled data or inability to improve generalization property.\nHere, we propose a transfer learning approach for hate speech understanding using a combination of the unsupervised pre-trained model BERT BIBREF11 and some new supervised fine-tuning strategies. As far as we know, it is the first time that such exhaustive fine-tuning strategies are proposed along with a generative pre-trained language model to transfer learning to low-resource hate speech languages and improve performance of the task. In summary:\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets. Toward that end, for the first time, we introduce new fine-tuning strategies to examine the effect of different embedding layers of BERT in hate speech detection.\nOur experiment results show that using the pre-trained BERT model and fine-tuning it on the downstream task by leveraging syntactical and contextual information of all BERT's transformers outperforms previous works in terms of precision, recall, and F1-score. Furthermore, examining the results shows the ability of our model to detect some biases in the process of collecting or annotating datasets. It can be a valuable clue in using pre-trained BERT model for debiasing hate speech datasets in future studies.\nWe propose a transfer learning approach using the pre-trained language model BERT learned on English Wikipedia and BookCorpus to enhance hate speech detection on publicly available benchmark datasets.",

        "answer": "Solving OKBC naturally provides the ground for knowledge learning and inference in conversations.",
        "evidence": "Chatbots such as dialog and question-answering systems have a long history in AI and natural language processing. Early such systems were mostly built using markup languages such as AIML, handcrafted conversation generation rules, and/or information retrieval techniques BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . Recent neural conversation models BIBREF4 , BIBREF5 , BIBREF6 are even able to perform open-ended conversations. However, since they do not use explicit knowledge bases and do not perform inference, they often suffer from generic and dull responses BIBREF5 , BIBREF7 . More recently, BIBREF8 and BIBREF9 proposed to use knowledge bases (KBs) to help generate responses for knowledge-grounded conversation. However, one major weakness of all existing chat systems is that they do not explicitly or implicitly learn new knowledge in the conversation process. This seriously limits the scope of their applications. In contrast, we humans constantly learn new knowledge in our conversations. Even if some existing systems can use very large knowledge bases either harvested from a large data source such as the Web or built manually, these KBs still miss a large number of facts (knowledge) BIBREF10 . It is thus important for a chatbot to continuously learn new knowledge in the conversation process to expand its KB and to improve its conversation ability.\nIn recent years, researchers have studied the problem of KB completion, i.e., inferring new facts (knowledge) automatically from existing facts in a KB. KB completion (KBC) is defined as a binary classification problem: Given a query triple, ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ), we want to predict whether the source entity INLINEFORM3 and target entity INLINEFORM4 can be linked by the relation INLINEFORM5 . However, existing approaches BIBREF11 , BIBREF12 , BIBREF13 , BIBREF14 , BIBREF15 , BIBREF16 solve this problem under the closed-world assumption, i.e., INLINEFORM6 , INLINEFORM7 and INLINEFORM8 are all known to exist in the KB. This is a major weakness because it means that no new knowledge or facts may contain unknown entities or relations. Due to this limitation, KBC is clearly not sufficient for knowledge learning in conversations because in a conversation, the user can say anything, which may contain entities and relations that are not already in the KB.\nIn this paper, we remove this assumption of KBC, and allow all INLINEFORM0 , INLINEFORM1 and INLINEFORM2 to be unknown. We call the new problem open-world knowledge base completion (OKBC). OKBC generalizes KBC. Below, we show that solving OKBC naturally provides the ground for knowledge learning and inference in conversations. In essence, we formulate an abstract problem of knowledge learning and inference in conversations as a well-defined OKBC problem in the interactive setting.\nFrom the perspective of knowledge learning in conversations, essentially we can extract two key types of information, true facts and queries, from the user utterances. Queries are facts whose truth values need to be determined. Note that we do not study fact or relation extraction in this paper as there is an extensive work on the topic. (1) For a true fact, we will incorporate it into the KB. Here we need to make sure that it is not already in the KB, which involves relation resolution and entity linking. After a fact is added to the KB, we may predict that some related facts involving some existing relations in the KB may also be true (not logical implications as they can be automatically inferred). For example, if the user says “Obama was born in USA,” the system may guess that (Obama, CitizenOf, USA) (meaning that Obama is a citizen of USA) could also be true based on the current KB. To verify this fact, it needs to solve a KBC problem by treating (Obama, CitizenOf, USA) as a query. This is a KBC problem because the fact (Obama, BornIn, USA) extracted from the original sentence has been added to the KB. Then Obama and USA are in the KB. If the KBC problem is solved, it learns a new fact (Obama, CitizenOf, USA) in addition to the extracted fact (Obama, BornIn, USA). (2) For a query fact, e.g., (Obama, BornIn, USA) extracted from the user question “Was Obama born in USA?” we need to solve the OKBC problem if any of “Obama, “BornIn”, or “USA\" is not already in the KB.\nWe can see that OKBC is the core of a knowledge learning engine for conversation. Thus, in this paper, we focus on solving it. We assume that other tasks such as fact/relation extraction and resolution and guessing of related facts of an extracted fact are solved by other sub-systems.\nWe solve the OKBC problem by mimicking how humans acquire knowledge and perform reasoning in an interactive conversation. Whenever we encounter an unknown concept or relation while answering a query, we perform inference using our existing knowledge. If our knowledge does not allow us to draw a conclusion, we typically ask questions to others to acquire related knowledge and use it in inference. The process typically involves an inference strategy (a sequence of actions), which interleaves a sequence of processing and interactive actions. A processing action can be the selection of related facts, deriving inference chain, etc., that advances the inference process. An interactive action can be deciding what to ask, formulating a suitable question, etc., that enable us to interact. The process helps grow the knowledge over time and the gained knowledge enables us to communicate better in the future. We call this lifelong interactive learning and inference (LiLi). Lifelong learning is reflected by the facts that the newly acquired facts are retained in the KB and used in inference for future queries, and that the accumulated knowledge in addition to the updated KB including past inference performances are leveraged to guide future interaction and learning. LiLi should have the following capabilities:\nThis setting is ideal for many NLP applications like dialog and question-answering systems that naturally provide the scope for human interaction and demand real-time inference.\nLiLi starts with the closed-world KBC approach path-ranking (PR) BIBREF11 , BIBREF17 and extends KBC in a major way to open-world knowledge base completion (OKBC). For a relation INLINEFORM0 , PR works by enumerating paths (except single-link path INLINEFORM1 ) between entity-pairs linked by INLINEFORM2 in the KB and use them as features to train a binary classifier to predict whether a query INLINEFORM3 should be in the KB. Here, a path between two entities is a sequence of relations linking them. In our work, we adopt the latest PR method, C-PR BIBREF16 and extend it to make it work in the open-world setting. C-PR enumerates paths by performing bidirectional random walks over the KB graph while leveraging the context of the source-target entity-pair. We also adopt and extend the compositional vector space model BIBREF20 , BIBREF21 with continual learning capability for prediction.\nGiven an OKBC query ( INLINEFORM0 , INLINEFORM1 , INLINEFORM2 ) (e.g., “(Obama, CitizenOf, USA), which means whether Obama a citizen of USA), LiLi interacts with the user (if needed) by dynamically formulating questions (see the interaction example in Figure 1, which will be further explained in §3) and leverages the interactively acquired knowledge (supporting facts (SFs) in the figure) for continued inference. To do so, LiLi formulates a query-specific inference strategy and executes it. We design LiLi in a Reinforcement Learning (RL) setting that performs sub-tasks like formulating and executing strategy, training a prediction model for inference, and knowledge retention for future use. To the best of our knowledge, our work is the first to address the OKBC problem and to propose an interactive learning mechanism to solve it in a continuous or lifelong manner. We empirically verify the effectiveness of LiLi on two standard real-world KBs: Freebase and WordNet. Experimental results show that LiLi is highly effective in terms of its predictive performance and strategy formulation ability.\nBelow, we show that solving OKBC naturally provides the ground for knowledge learning and inference in conversations.",

        "question": "How do they pre-train an ASR encoder?",
        "answer": "By optimizing the Connectionist Temporal Classification (CTC) (Graves et al. 2006) objective function.",
        "evidence": "Speech-to-Text translation (ST) is essential for a wide range of scenarios: for example in emergency calls, where agents have to respond emergent requests in a foreign language BIBREF0; or in online courses, where audiences and speakers use different languages BIBREF1. To tackle this problem, existing approaches can be categorized into cascaded method BIBREF2, BIBREF3, where a machine translation (MT) model translates outputs of an automatic speech recognition (ASR) system into target language, and end-to-end method BIBREF4, BIBREF5, where a single model learns acoustic frames to target word sequence mappings in one step towards the final objective of interest. Although the cascaded model remains the dominant approach due to its better performance, the end-to-end method becomes more and more popular because it has lower latency by avoiding inferences with two models and rectifies the error propagation in theory.\nSince it is hard to obtain a large-scale ST dataset, multi-task learning BIBREF5, BIBREF6 and pre-training techniques BIBREF7 have been applied to end-to-end ST model to leverage large-scale datasets of ASR and MT. A common practice is to pre-train two encoder-decoder models for ASR and MT respectively, and then initialize the ST model with the encoder of the ASR model and the decoder of the MT model. Subsequently, the ST model is optimized with the multi-task learning by weighing the losses of ASR, MT, and ST. This approach, however, causes a huge gap between pre-training and fine-tuning, which are summarized into three folds:\nSubnet Waste: The ST system just reuses the ASR encoder and the MT decoder, while discards other pre-trained subnets, such as the MT encoder. Consequently, valuable semantic information captured by the MT encoder cannot be inherited by the final ST system.\nRole Mismatch: The speech encoder plays different roles in pre-training and fine-tuning. The encoder is a pure acoustic model in pre-training, while it has to extract semantic and linguistic features additionally in fine-tuning, which significantly increases the learning difficulty.\nNon-pre-trained Attention Module: Previous work BIBREF6 trains attention modules for ASR, MT and ST respectively, hence, the attention module of ST does not benefit from the pre-training.\nTo address these issues, we propose a Tandem Connectionist Encoding Network (TCEN), which is able to reuse all subnets in pre-training, keep the roles of subnets consistent, and pre-train the attention module. Concretely, the TCEN consists of three components, a speech encoder, a text encoder, and a target text decoder. Different from the previous work that pre-trains an encoder-decoder based ASR model, we only pre-train an ASR encoder by optimizing the Connectionist Temporal Classification (CTC) BIBREF8 objective function. In this way, the additional decoder of ASR is not required while keeping the ability to read acoustic features into the source language space by the speech encoder. Besides, the text encoder and decoder can be pre-trained on a large MT dataset. After that, we employ common used multi-task learning method to jointly learn ASR, MT and ST tasks.\nCompared to prior works, the encoder of TCEN is a concatenation of an ASR encoder and an MT encoder and our model does not have an ASR decoder, so the subnet waste issue is solved. Furthermore, the two encoders work at tandem, disentangling acoustic feature extraction and linguistic feature extraction, ensuring the role consistency between pre-training and fine-tuning. Moreover, we reuse the pre-trained MT attention module in ST, so we can leverage the alignment information learned in pre-training.\nSince the text encoder consumes word embeddings of plausible texts in MT task but uses speech encoder outputs in ST task, another question is how one guarantees the speech encoder outputs are consistent with the word embeddings. We further modify our model to achieve semantic consistency and length consistency. Specifically, (1) the projection matrix at the CTC classification layer for ASR is shared with the word embedding matrix, ensuring that they are mapped to the same latent space, and (2) the length of the speech encoder output is proportional to the length of the input frame, so it is much longer than a natural sentence. To bridge the length gap, source sentences in MT are lengthened by adding word repetitions and blank tokens to mimic the CTC output sequences.\nWe conduct comprehensive experiments on the IWSLT18 speech translation benchmark BIBREF1, demonstrating the effectiveness of each component. Our model is significantly better than previous methods by 3.6 and 2.2 BLEU scores for the subword-level decoding and character-level decoding strategies, respectively.\nOur contributions are three-folds: 1) we shed light on why previous ST models cannot sufficiently utilize the knowledge learned from the pre-training process; 2) we propose a new ST model, which alleviates shortcomings in existing methods; and 3) we empirically evaluate the proposed model on a large-scale public dataset.\nDifferent from the previous work that pre-trains an encoder-decoder based ASR model, we only pre-train an ASR encoder by optimizing the Connectionist Temporal Classification (CTC) (Graves et al. 2006) objective function.",

        "evidence": "We evaluate our model on the zero-shot cross-lingual answer-aware question generation task. The goal of question generation (QG) is to generate a question that asks towards the answer with the given passage and the expected answer. In the following experiments, we extend the QG task to the cross-lingual setting. By only using English QG training data, our goal is to generate questions in English or Chinese with the given passage-answer pair in English or Chinese.\nWe use SQuAD 1.1 BIBREF30 as the English QG dataset. It is a popular English question answering dataset containing over 100,000 questions and their corresponding annotated passages. Following BIBREF31, we regard the original development set as the test set, and sample 5000 examples from the training data of two datasets as the development sets. For Chinese QG, we follow the default data splits of WebQA BIBREF32. We regard the provided annotated evidence sentences as the input passages instead of entire documents. To construct the input sequence, we view the whole input passage as a single sentence, and concatenate the passage and the answer into one sequence with a special token S between them. During decoding Chinese, we utilize a subset of vocabulary, which is obtained from the passage sentences of the WebQA dataset.\nWe first conduct experiments on the supervised English-English QG setting. We compare our model to the following baselines:\nCorefNqg BIBREF33 A sequence-to-sequence model with attention mechanism and a feature-rich encoder.\nMp-Gsn BIBREF31 A sequence-to-sequence model with gated self-attention and maxout pointer mechanism.\nXlm BIBREF5 The current state-of-the-art cross-lingual pre-training model. We initialize the Transformer-based sequence-to-sequence model with pre-trained XLM.\nWe evaluate models with BLEU-4 (BL-4), ROUGE (RG) and METEOR (MTR) metrics. As shown in Table TABREF16, our model outperforms the baselines, which demonstrates that our pre-trained model provides a good initialization for NLG.\nWe conduct experiments on the zero-shot Chinese-Chinese QG task to evaluate the cross-lingual transfer ability. In this task, models are trained with English QG data but evaluated with Chinese QG examples. We include the following models as our baselines:\nXlm Fine-tuning XLM with the English QG data.\nPipeline (Xlm) The pipeline of translating input Chinese sentences into English first, then performing En-En-QG with the XLM model, and finally translating back to the Chinese. We use the Transformer as the translator, which is also trained on the MultiUN dataset.\nPipeline (Xlm) with Google Translator Same to Pipeline (Xlm) but using Google Translator to translate the texts.\nWe evaluate models by both automatic evaluation metrics and human experts. The automatic metrics scores are computed by regarding each Chinese character as a token. For human evaluation, we consider three metrics for the generated questions: relatedness, fluency, and correctness, which are represented as integers ranged from 1 to 3. We randomly select 100 passage-answer pairs from the English QG test set, and use the models to generate questions. Then we present these examples to three experts to ask for the above scores. In Table TABREF17 and Table TABREF18, we present the results for the zero-shot Zh-Zh-QG. The results of monolingual supervised models are also reported in Table TABREF16 as reference. In the automatic evaluation, our model consistently performs better than baselines in both zero-shot and monolingual supervised setting. In the human evaluation, our model also obtains significant improvements in terms of relatedness and correctness.\nIn the zero-shot English-Chinese question generation experiments, we use Xlm and Pipeline (Xlm) as our baselines. Pipeline (Xlm) is a pipeline method that uses En-En-QG with Xlm to generate questions, and then translates the results to Chinese. Because there is no annotations for En-Zh-QG, we perform human evaluation studies for this setting. Table TABREF19 shows the human evaluation results, where our model surpasses all the baselines especially in terms of relatedness and correctness.\nWe also conduct experiments for zero-shot Chinese-English question generation, and adopt the same evaluation procedure to En-Zh-QG. Pipeline (Xlm) first translates Chinese input to English, and then conduct En-En-QG with Xlm. As shown in Table TABREF20, human evaluation results indicate that Xnlg achieves significant improvements on the three metrics.\nPIPELINE (XLM) is a pipeline method that uses En-En-QG with XLM to generate questions, and then translates the results to Chinese.",

        "answer": "In our experiment, we train each model five times independently and report the averaging performance score. We did not report the standard deviation because many comparing methods did not report it. In our revised version, we report the average standard deviation.",
        "evidence": "We adopt two evaluation metrics: segment-based and event-based metric. Segment-based metric is a widely adopted evaluation metric, it couples semantic label and spatial location together: a semantic-correctly detected sound source needs to be spatially close enough to its ground truth location in order to be regarded as a true positive detection. Event-based based metric is newly proposed by to comprehensively evaluate under different confidence scores. Like object detection from images, it computes mean average precision (mAP) and mean average recall (mAR) score.\nWe call our framework SoundSynp and compare it with four most recent methods: SELD-Net, EIN, SoundDet and Utsc-Iflytek. SELDNet is the baseline model and it jointly trains sound source's semantic label and spatial location with a convolutional recurrent neural network (CRNN). EIN) is a very recent work. It adopts multi-heads self-attention to model temporal dependency and trackwise permutation-invariant training to train the model. SoundDet directly learns from raw waveform with MaxCorr kernels, followed by an encoder-decoder neural network. Utsc-Iflytek is ranked first in DECASE2020 challenge leaderboard 1 , it combines MIC and FOA features and ensembles different models like ResNet and Xception(Chollet, 2017) to give final prediction.\nThe network architecture is shown in table in Appendix material. To train the neural network, we evenly divide the one minute long four-channel raw waveform into non-overlapping 4s short snippets. The raw waveform is first normalized to r´1, 1s before feeding the neural network. We adopt Adam optimizer with an initial learning rate 0.0002 in the first 100 epochs and 0.00007 in the following 50 epochs. Batchsize is 16. The loss combination weight between classification head and regression head is 1 : 2. During training, data augmentation method SpecAugment is applied. For DoA task, we regress direction of arrival angle in Cartesian coordinates rx, y, zs. In synperiodic filter bank groups, the filter length is 1025, each group's filter number is 256 and the step size is 600. Particularly, we have observed the initialized learnable synperiodic filter banks update its parameters intensively during the very early several epochs, and then gradually becomes stable. The final learned parameters are close to their initialization, one group's learned parameters (like frequency response and filter window length) is different from those learned by other groups, although they are initialized as the same in the start. We train each model five times independently and report the average score. The standard deviation is within 0.04 (for recall) and 0.2 ˝for angle, 0.003 for mAP and mAR.\nThe result is given in Table1, from which we see that SoundSynp achieves the best performance over all comparing methods by a large margin, under both segment-based and event-based metrics. Both SELDNet, EIN and UTSC-Iflytek use pre-extracted hand-engineered sound features, such as Logmel, GCC-Phat and Intensity Vector. SoundDet and SoundSynp are the only two methods that directly learn from raw waveforms. At the same time, SoundSynp obtains better performance on FOA than MIC format, the same phenomena has been observed by all other methods. It thus shows FOA better fits for sound source detection than MIC. It is worth noting that Utsc-Iflytek ensembles different powerful image-based 2D models to detect sound sources. However, our proposed SoundSynp still outperforms Utsc-Iflytek by a large margin. We don't report of mAP/mAR value for Utsc-Iflytek because it is a complex system and no detail about their system is available.\nAblation Study To disentangle the individual contribution of each part of our SoundSynp framework to the whole performance improvement, we conduct three ablation studies. First, the individual contribution of Synperiodic filter bank. We replace hand-engineered sound feature head of SELDNet, EIN and learnable MaxCorr filter bank with our proposed Synperiodic filter bank to test their corresponding performance. It helps to remove the influence of the backbone neural network of different models and thus helps to get direct comparison of synperiodic filter bank with other front-end. Second, we replace SoundSynp's synperiodic filter bank group with widely-used MFCC and Log-Mel that is used by and EIN, respectively. It disentangles synperiodic filter bank group with Transformer-like backbone, thus helps to figure out if the performance gain is simply brought by backbone network.\nThird, internally, we test five synperiodic variants: (1) synperiodic filter bank with just multiscale perception in frequency domain (SoundSynp MSFreq), (2) just multi-scale perception in time domain (SoundSynp MSTime), (3) Synperiodic filter bank with frequency responses linearly initialized in Nyquist frequency range (SoundSynp Linear, compare with our mel-scale initialization), (4) just one synperiodic filter bank without multi-scale perception neither in time nor frequency domain (SoundSynp SingleScale). () synperiodic filter bank with rectangular band-pass frequency response initialization (SoundSynp Sinc), like SincNet does. The internal comparison helps us to figure out the necessity of each part of synperiodic filter bank design.\nThe ablation study result is shown in Table. We can observe that: First, using synperiodic filter bank as a replacement of existing filter bank can help to improve the corresponding performance. Second, replacing SoundSynp's synperiodic filter bank with classic hand-engineered features inevitably reduces the performance under all evaluation metrics, its thus shows learning from pre-extracted fixed and single-scale sound representation leads to inferior performance than our proposed multiscale synperiodic filter bank. Third, the absence of multi-scale perception in either frequency domain or time domain inevitably reduces the performance. We find sound source semantic label detection suffers more in single-scale perception in time domain than in frequency domain (see better performance on ER 20 ˝, and F 20 ˝score), which shows frequency domain multi-scale perception is vital for semantic label estimation. Similarly, we can observe that multi-scale perception in time domain is vital for sound source spatial location estimation (see better performance on LE and LR score). Linearly initialized filter bank frequency response reduces the performance, which shows assigning more filters to the lower frequency range is important. But this conclusion might be data-dependent because we find DCASE dataset contains many low-frequency sounds like burning fire and footsteps. Moreover, reducing the synperiodic filter bank group to one groups with just singlescale perception leads to comparably the worst performance, it thus shows multi-scale perception in both time and frequency domain is essential for DoA-based sound source detection. Lastly, SoundSynp Sinc leads to slightly inferior performance than our used mel-scale initialization strategy, it shows our proposed synperiodic filter bank is a general filter bank that can be adopted to other frequency sensitive filter bank.  One qualitative comparison is shown in Fig.. We can clearly see that SELDNet generates mixed prediction at different time steps and DoA locations. SoundDet and EIN give non-existing sound sources (orange color). When multiple sound sources happen at the same time (polyphonicity), SoundDet and EIN are easily failed to predict the right spatial location (discretized blue and red color). Our method predicts more spatially and temporally consistent sound sources by maximally keeping sound source's continuity and consistency.\nWe train each model five times independently and report the average score. The standard deviation is within 0.04 (for recall) and 0.2 ˝ for angle, 0.003 for mAP and mAR.",

She was awarded the third highest civilian award Padma Bhushan by Government of India in 2019.\n\nBachendri Pal was born to a Bhotiya family on 24 May 1954 in Nakuri village, in the Uttarkashi district in the Indian state of Uttarakhand. She was one of five children to Hansa Devi, and Shri Kishan Singh Pal, – a border tradesman who supplied groceries from India to Tibet. She was born only five days prior to the first anniversary of the original ascension of Mount Everest by Tenzing Norgay and Edmund Hillary. She completed her M.A. and B.Ed. from D.A.V. Post Graduate College, Dehradun. She started mountaineering at the age of 12 when, along with her friends, she scaled a 13,123 ft (3,999.9 m) high peak during a school picnic. On the invitation of her school principal, she was sent to college for higher studies and, during her course at Nehru Institute of Mountaineering, became the first female to climb Mount Gangotri 23,419 ft (7,138.1 m) and Mount Rudragaria 19,091 ft (5,818.9 m) in 1982. In that time, she became an instructor at the National Adventure Foundation (NAF), which had set up an adventure school for training women to learn mountaineering.\n\nPal encountered stiff opposition from her family and relatives when she chose a career as a professional mountaineer rather than a schoolteacher. However, she soon found success in her chosen field when, after summiting a number of smaller peaks, she was selected to join India's first mixed-gender team to attempt an expedition to Mount Everest in 1984.\n\nBachendri Pal has been conferred with following awards and accolades:\n\nGold Medal for Excellence in Mountaineering by the Indian Mountaineering Foundation (1984)\nPadma Shri – the fourth highest civilian award of the Republic of India (1984)\nGold Medal by the Department of Education, Government of Uttar Pradesh, India (1985)\nArjuna Award by the Government of India (1986)\nCalcutta Ladies Study Group Award (1986)\nListed in the Guinness Book of World Records (1990)\nNational Adventure Award by the Government of India (1994)\nYash Bharti Award by the Government of Uttar Pradesh, India (1995)\nHonorary Doctorate from the Hemwati Nandan Bahuguna Garhwal University (formerly known as Garhwal University) (1997)\nShe is the first recipient of the Virangana Lakshmibai Rashtriya Samman 2013–14, which was given by the Ministry of Culture, Government of Madhya Pradesh, India at Gwalior on 18 June 2013 for her personal achievement in adventure sports and women's upliftment in the country.\nPadma Bhushan – the third highest civilian award of the Republic of India (2019)\nBharat Gaurav Award by East Bengal Club: 2014",

        "evidence": "In the 1960s, English county teams began playing a version of cricket with games of only one innings each and a maximum number of overs per innings. Starting in 1963 as a knockout competition only, limited-overs cricket grew in popularity and, in 1969, a national league was created which consequently caused a reduction in the number of matches in the County Championship. The status of limited overs matches is governed by the official List A categorisation. Although many \"traditional\" cricket fans objected to the shorter form of the game, limited-overs cricket did have the advantage of delivering a result to spectators within a single day; it did improve cricket's appeal to younger or busier people; and it did prove commercially successful.\n\nThe first limited-overs international match took place at Melbourne Cricket Ground in 1971 as a time-filler after a Test match had been abandoned because of heavy rain on the opening days. It was tried simply as an experiment and to give the players some exercise, but turned out to be immensely popular. limited-overs internationals (LOIs or ODIs—one-day internationals) have since grown to become a massively popular form of the game, especially for busy people who want to be able to see a whole match. The International Cricket Council reacted to this development by organising the first Cricket World Cup in England in 1975, with all the Test-playing nations taking part.",

        "evidence": "Automated, or robotic, journalism aims at news generation from structured data sources, either as the final product or as a draft for subsequent post-editing. At present, automated journalism typically focuses on domains such as sports, finance and similar statistics-based reporting, where there is a commercial product potential due to the high volume of news, combined with the expectation of a relatively straightforward task.\nNews generation systems—especially those deployed in practice—tend to be based on intricate template filling, aiming to give the users the full control of the generated facts, while maintaining a reasonable variability of the resulting text. This comes at the price of having to develop the templates and specify their control logic, neither of which are tasks naturally fitting journalists' work. Further, this development needs to be repeated for every domain, as the templates are not easily transferred across domains. Examples of the template-based news generation systems for Finnish are Voitto by the Finnish Public Service Broadcasting Company (YLE) used for sports news generation, as well as Vaalibotti BIBREF0, a hybrid machine learning and template-based system used for election news.\nBIBREF1 suggested a neural template generation, which jointly models latent templates and text generation. Such a system increases interpretability and controllability of the generation, however, recent sequence-to-sequence systems represent the state-of-the-art in data-to-text generation. BIBREF2\nIn this paper, we report on the development of a news generation system for the Finnish ice hockey news domain, based on sequence-to-sequence methods. In order to train such a system, we compile a corpus of news based on over 2000 game reports from the Finnish News Agency STT. While developing this corpus into a form suitable for training of end-to-end systems naturally requires manual effort, we argue that compiling and refining a set of text examples is a more natural way for journalists to interact with the system, in order for them to codify their knowledge and to adapt it for new domains.\nOur aim is to generate reports that give an overview of a game based on information inferrable from the statistics. Such reports can be used either as a basis for further post-editing by a journalist imprinting own insights and background information, or even used directly as a news stream labelled as machine-generated.\nIn the following, we will introduce the news dataset and the process of its creation, introduce an end-to-end model for news generation, and evaluate its output respective to the abovementioned objectives.\nIn this paper, we report on the development of a news generation system for the Finnish ice hockey news domain, based on sequence-to-sequence methods.",

However, smaller datasets are problematic because they contain too little linguistic variation and increase the likelihood of overfitting. Rizoiu et al.BIBREF61 train detection models on only a proportion of the Davidson et al. and Waseem training datasets and show that this leads to worse performance, with a lower F1-Score, particularly for `data hungry' deep learning approaches BIBREF61. At the same time, `big' datasets alone are not a panacea for the challenges of abusive content classification. Large training datasets which have been poorly sampled, annotated with theoretically problematic categories or inexpertly and unthoughtfully annotated, could still lead to the development of poor classification systems.\nThe size of the training datasets varies considerably from 469 posts to 17 million; a difference of four orders of magnitude.",

As the amount of data that can be mined for opinion increased, commercial companies' interests for sentiment analysis increased as well. Sentiment analysis is an important part of understanding user behavior and opinions on products, places, or services.\nSentiment analysis has long been studied by the research community, leading to several sentiment-related resources such as sentiment dictionaries that can be used as features for machine learning models BIBREF0 , BIBREF1 , BIBREF2 , BIBREF3 . These resources help increase sentiment analysis accuracies; however, they are highly dependent on language and require researchers to build such resources for every language to process.\nFeature engineering is a large part of the model building phase for most sentiment analysis and emotion detection models BIBREF4 . Determining the correct set of features is a task that requires thorough investigation. Furthermore, these features are mostly language and dataset dependent making it even further challenging to build models for different languages. For example, the sentiment and emotion lexicons, as well as pre-trained word embeddings are not completely transferable to other languages which replicates the efforts for every language that users would like to build sentiment classification models on. For languages and tasks where the data is limited, extracting these features, building language models, training word embeddings, and creating lexicons are big challenges. In addition to the feature engineering effort, the machine learning models' parameters also need to be tuned separately for each language to get the optimal results.\nIn this paper, we take a different approach. We build a reusable sentiment analysis model that does not utilize any lexicons. Our goal is to evaluate how well a generic model can be used to mine opinion in different languages where data is more limited than the language where the generic model is trained on. To that end, we build a training set that contains reviews from different domains in English (e.g., movie reviews, product reviews) and train a recurrent neural network (RNN) model to predict polarity of those reviews. Then focusing on a domain, we make the model specialized in that domain by using the trained weights from the larger data and further training with data on a specific domain. To evaluate the reusability of the sentiment analysis model, we test with non-English datasets. We first translate the test set to English and use the pre-trained model to score polarity in the translated text. In this way, our proposed approach eliminates the need to train language-dependent models, use of sentiment lexicons and word embeddings for each language. Our experiments show that a generalizable sentiment analysis model can be utilized successfully to perform opinion mining for languages that do not have enough resources to train specific models.\nThe contributions of this study are; 1) a robust approach that utilizes machine translation to reuse a model trained on one language in other languages, 2) an RNN-based approach to eliminate feature extraction as well as resource requirements for sentiment analysis, and 3) a technique that statistically significantly outperforms baselines for multilingual sentiment analysis task when data is limited. To the best of our knowledge, this study is the first to apply a deep learning model to the multilingual sentiment analysis task.\nWith the steady growth in the commercial websites and social media venues, the access to users’ reviews have become easier.

This presupposes large quantities of monolingual data in each of the languages that needs to be covered and each model with its parameters is completely independent of any of the other models.\nWe propose instead to use a single model with real-valued vectors to indicate the language used, and to train this model with a large number of languages.

In this paper, we explore the “language space” containing these vectors, and in particular explore what happens when we move beyond the points representing the languages of the training corpus.\nThe motivation of combining languages into one single model is at least two-fold: First of all, languages are related and share many features and properties, a fact that is ignored when using independent models. The second motivation is data sparseness, an issue that heavily influences the reliability of data-driven models. Resources are scarce for most languages in the world (and also for most domains in otherwise well-supported languages), which makes it hard to train reasonable parameters. By combining data from many languages, we hope to mitigate this issue.\nIn contrast to related work, we focus on massively multilingual data sets to cover for the first time a substantial amount of the linguistic diversity in the world in a project related to data-driven language modeling. We do not presuppose any prior knowledge about language similarities and evolution and let the model discover relations on its own purely by looking at the data. The only supervision that is giving during training is a language identifier as a one-hot encoding. From that and the actual training examples, the system learns dense vector representations for each language included in our data set along with the character-level RNN parameters of the language model itself.\nThe only supervision that is giving during training is a language identifier as a one-hot encoding.",

They investigated whether the collective mood states of public (Happy, calm, Anxiety) derived from twitter feeds are correlated to the value of the Dow Jones Industrial Index. They used a Fuzzy neural network for their prediction. Their results show that public mood states in twitter are strongly correlated with Dow Jones Industrial Index. Chen and Lazer BIBREF11 derived investment strategies by observing and classifying the twitter feeds. Bing et al. BIBREF12 studied the tweets and concluded the predictability of stock prices based on the type of industry like Finance, IT etc. Zhang BIBREF13 found out a high negative correlation between mood states like hope, fear and worry in tweets with the Dow Jones Average Index. Recently, Brian et al. BIBREF14 investigated the correlation of sentiments of public with stock increase and decreases using Pearson correlation coefficient for stocks. In this paper, we took a novel approach of predicting rise and fall in stock prices based on the sentiments extracted from twitter to find the correlation. The core contribution of our work is the development of a sentiment analyzer which works better than the one in Brian's work and a novel approach to find the correlation. Sentiment analyzer is used to classify the sentiments in tweets extracted.The human annotated dataset in our work is also exhaustive. We have shown that a strong correlation exists between twitter sentiments and the next day stock prices in the results section.

        "evidence": "Legal documents are a rather heterogeneous class, which also manifests in their linguistic properties, including the use of named entities and references. Their type and frequency varies significantly, depending on the text type. Texts belonging to specific text type, which are to be selected for inclusion in a corpus must contain enough different named entities and references and they need to be freely available. When comparing legal documents such as laws, court decisions or administrative regulations, decisions are the best option. In laws and administrative regulations, the frequencies of person, location and organization are not high enough for NER experiments. Court decisions, on the other hand, include person, location, organization, references to law, other decision and regulation.\nCourt decisions from 2017 and 2018 were selected for the dataset, published online by the Federal Ministry of Justice and Consumer Protection. The documents originate from seven federal courts: Federal Labour Court (BAG), Federal Fiscal Court (BFH), Federal Court of Justice (BGH), Federal Patent Court (BPatG), Federal Social Court (BSG), Federal Constitutional Court (BVerfG) and Federal Administrative Court (BVerwG).\nFrom the table of contents, 107 documents from each court were selected (see Table ). The data was collected from the XML documents, i. e., it was extracted from the XML elements Mitwirkung, Titelzeile, Leitsatz, Tenor, Tatbestand, Entscheidungsgründe, Gründen, abweichende Meinung, and sonstiger Titel. The metadata at the beginning of the documents (name of court, date of decision, file number, European Case Law Identifier, document type, laws) and those that belonged to previous legal proceedings was deleted. Paragraph numbers were removed. The extracted data was split into sentences, tokenised using SoMaJo BIBREF16 and manually annotated in WebAnno BIBREF17.\nThe annotated documents are available in CoNNL-2002. The information originally represented by and through the XML markup was lost in the conversion process. We decided to use CoNNL-2002 because our primary focus was on the NER task and experiments. CoNNL is one of the best practice formats for NER datasets. All relevant tools support CoNNL, including WebAnno for manual annotation. Nevertheless, it is possible, of course, to re-insert the annotated information back into the XML documents.\nThe dataset consists of 66,723 sentences with 2,157,048 tokens (incl. punctuation), see Table 1.
